Description

Technical Field

[0002] Processing equipment, such as 3D printers, (laser) cutters, and laser engravers, can provide printing, cutting, and engraving capabilities, enabling the manufacture of complex items that are impossible with traditional manufacturing techniques (such as injection molding or manual assembly). In the specific implementation of processing, slicing software can be provided to the processing equipment. Instructions can be sent from the slicing software to the processing equipment, or copied to the processing equipment via storage devices such as USB drives. The processing equipment can then execute these instructions to provide a series of steps in the manufacturing process. Currently, the print head, laser head, and cutter head are relatively independently configured. When different processing methods are required, the print head, laser head, and cutter head need to be disassembled and reassembled separately, a cumbersome process involving multiple disassemblies and reassemblies.

[0084] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0085] Please see Figure 1 and Figure 2 This application provides a processing device, including a first component 100, a second component 200, a guide component 300, and a processing platform 400. In some feasible embodiments, the processing device is a gantry structure (e.g., Figure 1As shown, the guide 300 is supported by two vertical columns along the Z-axis. The guide 300 can move up and down along the Z-axis, and the first device 100 can move along the guide 300 in the Y-axis direction and along the machining platform 400 in the X-axis direction. Optionally, the machining equipment can be a corexy structure, with the guide supported by a frame on the machining equipment. The first device can move along the guide in the XY plane under the drive of a belt. The machining platform is connected to a Z-axis lead screw to achieve movement in the Z-axis direction. For example, the guide can be at least one of a Y-axis linear guide, a carbon rod, and an X-axis optical axis. Optionally, the machining equipment can also be a cantilever structure, with the guide supported by one Z-axis column. The guide can move up and down along the Z-axis, and the first device can move along the guide in the Y-axis direction and along the machining platform in the X-axis direction.

[0086] It should be understood Figure 1 This is merely an illustration and does not limit the structural type of the processing equipment. In this application, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. "Connection" includes detachable and non-detachable connections. For example, a fixed connection can include detachable fixed connections and non-detachable fixed connections, a rotating connection can include detachable rotating connections and non-detachable rotating connections, and a sliding connection can include detachable sliding connections and non-detachable sliding connections. A connection can also be a direct connection or an indirect connection through a component. For example, a detachable fixed connection refers to a connection where the positional relationship between at least two connected objects can be fixed in the installed state; similar examples include rotating connections and sliding connections.

[0087] In some feasible embodiments, the processing platform 400 serves as a platform for processing the first device 100 and the second device 200. The guide member 300 supports the first device 100 and the second device 200. The first device 100 is slidably connected to the guide member 300, and during processing, the first device 100 can slide linearly along the Y-axis direction of the guide member 300 or slide in the XY plane via a belt. The guide member 300 is movably connected to the frame of the processing platform 400, and the guide member 300 can move relative to the frame of the processing platform 400 along the X-axis direction and also along the Z-axis direction. This allows the first device 100 to move along the X-axis direction relative to the frame of the processing platform 400, and also allows the first device 100 to move up and down along the Z-axis direction relative to the frame of the processing platform 400, following the movement of the guide member 300. The sliding of the first device 100 along the Y-axis direction of the guide 300, the movement of the first device 100 along the X-axis direction following the guide 300, and the up-and-down movement of the first device 100 along the Z-axis direction following the guide 300 can be coordinated by a stepper motor and a transmission system. This allows the stepper motor to drive the first device 100 to move precisely in three-dimensional space via a lead screw, ensuring that the material processed by the first device 100 is shaped according to the designed trajectory.

[0088] Please see Figure 3 and Figure 4 The first device 100 is provided with a mounting part 115, and the second device 200 is provided with a connecting part 215. The first device 100 and the second device 200 are connected by the cooperation of the mounting part 115 and the connecting part 215. There are various ways in which the mounting part 115 and the connecting part 215 are cooperated. For example, the mounting part 115 and the connecting part 215 can be cooperated by a snap-fit ​​part and a limiting groove. The limiting groove is provided in the mounting part 115, and the snap-fit ​​part is provided in the connecting part 215. The snap-fit ​​part extends into the limiting groove, so that the connecting part 215 clamps the mounting part 115, thereby connecting the first device 100 and the second device 200. For example, the connecting portion 215 is provided with a corresponding protrusion as a snap-fit ​​portion. The second device 200 can be slidably installed onto the first device 100 from top to bottom. The snap-fit ​​portion on the connecting portion 215 of the second device 200 extends into the limiting groove provided on the mounting portion 115 of the first device 100, thus snapping the connecting portion 215 of the second device 200 onto the mounting portion 115 of the first device 100, thereby connecting the second device 200 and the first device 100. This facilitates the installation and removal of the first device 100 and the second device 200, improving the installation efficiency of the first device 100 and the second device 200. Optionally, the second device 200 can be installed onto the first device 100 by snap-fit ​​clamping; or the second device 200 can be hung on the first device 100 by magnetic attraction.

[0089] Please see Figure 5 and Figure 6 The mounting portion 115 is provided with a first limiting groove 120 and a second limiting groove 130 spaced apart. The mounting portion 115 is provided with a first protruding rib 122 and a second protruding rib 132 spaced apart. The first protruding rib 122 and the second protruding rib 132 are provided on the surface of the main body of the first device 100 facing the second device 200. A first inclined surface 124 is formed on the side of the first protruding rib 122 facing away from the second protruding rib 132, and a second inclined surface 134 is formed on the side of the second protruding rib 132 facing away from the first protruding rib 122. The first inclined surface 124 and the surface of the main body of the first device 100 facing the second device 200 form the first limiting groove 120, and the second inclined surface 134 and the surface of the main body of the first device 100 facing the second device 200 form the second limiting groove 130. The connecting portion 215 is provided with a first latching portion 220 and a second latching portion 230, which are spaced apart from the first latching portion 220. The side of the first latching portion 220 facing the second latching portion 230 has a third inclined surface 224, which contacts the first inclined surface 124. The side of the second latching portion 230 facing the first latching portion 220 has a fourth inclined surface 234, which contacts the second inclined surface 134. The first latching portion 220 is used to extend into the first limiting groove 120; the second latching portion 230 is used to extend into the second limiting groove 130. After the first latching portion 220 and the second latching portion 230 extend into the first limiting groove 120 and the second limiting groove 130 respectively, the connecting portion 215 is fastened onto the mounting portion 115, thereby connecting the second device 200 and the first device 100. The first latching part 220 and the first limiting groove 120 are in contact through the third inclined surface 224 and the first inclined surface 124, ensuring the precise positioning of the first latching part 220 and the first limiting groove 120. The second latching part 230 and the second limiting groove 130 are in contact through the fourth inclined surface 234 and the second inclined surface 134, ensuring the precise positioning of the second latching part 230 and the second limiting groove 130, thereby ensuring the precise positioning of the second device 200 and the first device 100.

[0090] The mounting portion 115 has a plurality of first reinforcing ribs 126 on the side of the first rib 122 facing away from the first inclined surface 124, and a plurality of second reinforcing ribs 132 on the side of the second rib facing away from the second inclined surface 134. The plurality of first reinforcing ribs 126 are disposed on the surface of the first device 100 facing the second device 200, and one end of each first reinforcing rib 126 perpendicular to the surface of the first device 100 facing the second device 200 is connected to the side of the first rib 122 facing away from the first inclined surface 124. The first reinforcing ribs 126 and the second reinforcing ribs 136 strengthen the connection between the first rib 122 and the surface of the first device 100, dispersing the stress on the first rib 122 when it bears an object, and improving the strength and rigidity of the first rib 122 without increasing the overall wall thickness. Multiple second reinforcing ribs 136 are disposed on the surface of the first device 100 facing the second device 200. One end of each second reinforcing rib 136, perpendicular to the surface of the first device 100 facing the second device 200, is connected to the side of the second rib 132 facing away from the first inclined surface 124. The multiple second reinforcing ribs 136 strengthen the connection between the second rib 132 and the surface of the first device 100, dispersing the stress experienced by the second rib 132 when bearing an object, and improving the strength and rigidity of the second rib 132 without increasing the overall wall thickness. The support of the first reinforcing ribs 126 and the second reinforcing ribs 136 increases the load-bearing capacity of the mounting portion 115, enabling the mounting portion 115 to better resist deformation and reducing the risk of the first device 100 and the second device 200 detaching during processing and production.

[0091] The first limiting groove 120 and the second limiting groove 130 are arranged along the depth direction of the first device 100, and both the first limiting groove 120 and the second limiting groove 130 extend along the height direction of the first device 100. The depth direction of the first device 100 is the Y-axis direction, and the height direction of the first device is the Z-axis direction. The first limiting groove 120 and the second limiting groove 130 are arranged along the height direction of the first device 100, so that when the second device 200 is connected to the first device 100, the connecting part 215 slides into the mounting part 115 from top to bottom by the gravity of the second device 200 itself, so that the first locking part 220 and the second locking part 230 slide smoothly into the first limiting groove 120 and the second limiting groove 130. The operation is simple and convenient, and the installation efficiency is improved.

[0092] Please see Figure 5 and Figure 6The mounting portion 115 further includes a first support rib 121 and a second support rib 131 disposed on the surface of the main body of the first device 100 facing the second device 200. The first support rib 121 is connected to the first protruding rib 122, and the second support rib 131 is connected to the second protruding rib 132. The connecting portion 215 includes a boss 262 disposed on the surface of the main body of the second device 200 facing the first device 100. For example, the first support rib 121 may be a reinforcing rib of the first reinforcing rib 126 that contacts the boss 262, and the second support rib 131 may be a reinforcing rib of the second reinforcing rib 136 that contacts the boss 262. The first support rib 121 and the second support rib 131 together support the boss 262. The first support rib 121 is disposed at the end of the first protruding rib 122 facing the top surface of the first device 100, and the second support rib 131 is disposed at the end of the second protruding rib 132 facing the top surface of the first device 100. After the first snap-fit ​​portion 220 and the second snap-fit ​​portion 230 of the connecting portion 215 extend into the first limiting groove 120 and the second limiting groove 130, the boss 262 of the connecting portion 215 rests on the first support rib 121 and the second support rib 131. At this time, the second snap-fit ​​portion 230 and the first snap-fit ​​portion 220 no longer extend into the second limiting groove 130 and the first limiting groove 120. The mounting portion 115 supports the connecting portion 215 through the first support rib 121, the second support rib 131, the first protruding rib 122 and the second protruding rib 132, the first reinforcing rib 126 and the second reinforcing rib 136, and positions the connecting portion 215 by supporting the connecting portion 215 through the first support rib 121 and the second support rib 131. The mounting portion 115 of the first device 100 and the connecting portion 215 of the second device 200 are connected by extending into the first limiting groove 120 and the second limiting groove 130 through the first snap-fit ​​portion 220 and the second snap-fit ​​portion 230. The boss 262 of the connecting portion 215 is supported by the first support rib 121 and the second support rib 131 of the mounting portion 115, thereby realizing the snap-fit ​​connection between the first device 100 and the second device 200, reducing the risk of the first device 100 and the second device 200 falling off during processing and production on the processing equipment, and improving the installation and positioning efficiency between the first device 100 and the second device 200.

[0093] Please see Figure 6The connecting portion 215 also includes a locking member 250. The locking member 250, together with the first latching portion 220 and the second latching portion 230, is used to clamp the mounting portion 115 of the first device 100, so that the second device 200 is connected to the first device 100. The first latching portion 220 and the second latching portion 230 are spaced apart on the surface of the second device 200 facing the first device 100. The first latching portion 220 is fixedly connected to the main body of the second device 200, and the second latching portion 230 is movably connected to the main body of the second device 200. The first latching portion 220 and the second latching portion 230 are located at the two side edges of the second device 200, facilitating the insertion of the first latching portion 220 into the first limiting groove 120 and the second latching portion 230 into the second limiting groove 130. The second latching portion 230 is movably connected to the main body of the second device 200, allowing the second latching portion 230 to be detached from the main body of the second device 200. When removing the second device 200 from the first device 100, you can either slide out the first latching part 220 and the second latching part 230, or you can remove the second latching part 230 and then remove the second device 200. Alternatively, you can loosen the locking member 250 on the connecting part 215 to increase the distance between the first latching part 220 and the second latching part 230, thereby removing the second device from the first device. The first latching portion 220 and the second latching portion 230 extend into the first limiting groove 120 and the second limiting groove 130, respectively. The boss 262 of the connecting portion 215 rests on the first support rib 121 and the second support rib 131 of the mounting portion 115. The locking member 250 on the connecting portion 215 locks / presses the second latching portion 230. By reducing the distance between the first latching portion 220 and the second latching portion 230, the stress between the first latching portion 220 and the first limiting groove 120 and the second latching portion 230 and the second limiting groove 130 is increased. This further secures the connecting portion 215 of the second device 200 onto the mounting portion 115 of the first device 100, reducing the risk of the first device 100 and the second device 200 falling off during processing and production on the processing equipment.

[0094] A connecting portion 215 is disposed at a first segment 260 and a second segment 261 that are fixedly connected to the main body of the second device 200. The first segment 260 and the second segment 261 are spaced apart and both extend into the second limiting groove 130. A second snap-fit ​​portion 230 is located between the first segment 260 and the second segment 261. The first segment 260 and the second segment 261 are fixedly connected to the main body of the second device 200. The side of the first segment 260 and the second segment 261 facing the first snap-fit ​​portion 220 also has a fourth inclined surface 234, which contacts the second inclined surface 134. The first segment 260 and the second segment 261 are disposed at both ends of the second snap-fit ​​portion 230. When the second device 200 is connected to the first device 100, the first segment 260 and the second segment 261, together with the second snap-fit ​​portion 230, extend into the second limiting groove 130. When the second snap-fit ​​part 230 is disassembled at the connecting part 215, the first segment 260 and the second segment 261 extend into the second limiting groove 130, preventing the second device 200 from falling off the first device 100 and ensuring the safety of the installation work. In addition, the second segment 261 ensures that when the first device 100 and the second device 200 are connected, there is a partial overlap between the second snap-fit ​​part 230 and the second protrusion 132, preventing the second snap-fit ​​part 230 from getting stuck in the second protrusion 132 / second limiting groove 130 when it is released, which would cause the second device 200 to get stuck when disassembling from the first device 100.

[0095] The locking member 250 is fixedly connected to the main body of the second device 200. The locking member 250 is used to press against the second latching part 230 so that the second latching part 230 and the first latching part 220 clamp the mounting part 115. After the first latching part 220 and the second latching part 230 extend into the first limiting groove 120 and the second limiting groove 130 for clamping, the locking member 250 presses against the second latching part 230, reducing the gap between the second latching part 230 and the second limiting groove 130, and between the first latching part 220 and the first limiting groove 120. This increases the force between the second latching part 230 and the second limiting groove 130, and between the first latching part 220 and the first limiting groove 120, making the clamping of the mounting part 115 by the first latching part 220 and the second latching part 230 more secure, reducing the risk of falling off during production and processing, and improving the safety factor of the processing equipment.

[0096] Please see Figure 7An elastic element 253 connects the second latching portion 230 and the main body of the second device 200. The locking element 250 includes a fixing bolt 251 and a cam wrench 252. The fixing bolt 251 passes through the second latching portion 230 and is fixedly connected to the main body of the second device 200. The cam wrench 252 is hinged to the fixing bolt 251 and presses against the surface of the second latching portion 230 facing away from the elastic element 253. The elastic element 253 between the second latching portion 230 and the second device 200 cooperates with the locking element 250 to clamp the second latching portion 230 and the first latching portion 220 with the second limiting groove 130 and the first limiting groove 120. When the cam wrench 252 is lifted, the elastic element 253 is in a relaxed state, and the elastic element 253 between the locking element 250 and the second device 200 does not generate clamping force at this time. After the cam wrench 252 is pressed down, it positions and fixes the fixing bolt 251. The fixing bolt 251 of the locking member 250 presses against the elastic member 253 between the second locking part 230 and the second device 200. The elastic member 253 is in a compressed state, which makes the second locking part 230 and the second limiting groove 130 pressed together. This increases the stress between the first locking part 220 and the first limiting groove 120, and between the second locking part 230 and the second limiting groove 130. As a result, the locking member 250, together with the first locking part 220 and the second locking part 230, clamps the hanging part 115. This makes the clamping of the first locking part 220 and the second locking part 230 on the hanging part 115 more secure, reduces the risk of falling off during production and processing, and improves the safety factor of the processing equipment.

[0097] The surface of the cam wrench 252 facing away from the second latching portion 230 is marked. The processing equipment is also equipped with a first camera for photographing the mark. The first camera photographs the mark, which can be a graphic shape, such as multiple circular icons, square icons, triangular icons, or even a QR code shape. This application does not limit the specific implementation of the mark. By analyzing the mark, the raised and lowered states of the cam wrench 252 of the locking member 250 are determined to determine whether the locking member 250 is locked. The mark can improve the accuracy of identification. When the locking member 250 is not locked before processing or when the locking member 250 is not locked during processing, an alarm is triggered. In this application, the first camera is set on the first device 100 or the second device 200, or the first camera is set on the chassis / frame of the processing equipment. During or after the processing equipment begins processing, a first camera takes a picture of the cam wrench 252. A processor within the processing equipment analyzes the image captured by the first camera. After taking a picture of the cam wrench 252, the first camera transmits the image to the processor. The processor identifies the markings on the cam wrench 252 captured by the first camera. When the cam wrench 252 is detected as being in a depressed state, it determines that the locking member 250 is engaged with the second latching part 230. The processor then transmits a motion command to the first device 100 via the first cable 111. The first device 100 transmits the motion command to the second device 200, and both devices begin operation. When the cam wrench 252 is detected as being in a raised state, it determines that the locking member 250 is not engaged with the second latching part 230. The processor then issues an alarm to remind the operator to engage the locking member 250. By using the markings on the cam wrench 252 captured by the first camera to determine the engagement status of the locking member 250, the safety of the processing equipment during production is improved.

[0098] Please see Figure 5 and Figure 6The first device 100 includes a reference positioning element, and the second device 200 includes a positioning alignment element. When the second device 200 is connected to the first device 100, the reference positioning element and the positioning alignment element have a preset positional relationship. The reference positioning element on the first device 100 and the positioning alignment element on the second device 200 are used to help position the mounting portion 115 of the first device 100 and the connecting portion 215 of the second device 200. The preset positional relationship between the reference positioning element and the positioning alignment element is used to determine the position when the mounting portion 115 of the first device 100 is connected to the connecting portion 215 of the second device 200, thereby determining whether the second device 200 is installed in place. When the first device 100 and the second device 200 are connected, the reference positioning element and the positioning alignment element are aligned, improving the alignment accuracy of the mounting portion 115 and the connecting portion 215, thereby improving the installation accuracy of the first device 100 and the second device 200. For example, in this application, the reference positioning member includes a positioning recess 117 disposed on the surface of the first device 100 facing the second device 200, and the positioning alignment member includes a positioning protrusion 217 on the surface of the second device 200 facing the first device 100. When the first device 100 is connected to the second device 200, the first engaging portion 220 and the second engaging portion 230 of the connecting portion 215 extend into the first limiting groove 120 and the second limiting groove 130, and the positioning protrusion 217 on the second device 200 engages with the positioning recess 117 on the first device 100, ensuring the preset relationship between the reference positioning member and the positioning alignment member. The positions of the positioning protrusion 217 and the positioning recess 117 can be adjusted according to the actual state. For example, the positioning protrusion 217 can be disposed between the first engaging portion 220 and the second engaging portion 230, and the positioning recess 117 can be disposed between the first limiting groove 120 and the second limiting groove 130. After the positioning protrusion 217 and the positioning recess 117 are aligned, the first device 100 and the second device 200 can be installed, which improves the installation accuracy of the first device 100 and the second device 200, facilitates the installation of the first device 100 and the second device 200, and improves production efficiency.

[0099] For some feasible implementation methods, please refer to Figure 5 The reference positioning element of the first device 100 may include a first cooling fan 103, which is used to blow air onto the 3D print head. For example, the hot end of the 3D print head includes a nozzle and heat sink fins. The first cooling fan 103 blows air onto the heat sink fins to help dissipate heat from the hot end. The first cooling fan 103 is mounted on one side of the nozzle 140. During the 3D printing process, the printing material is heated and melted by the hot end, and then extruded through the nozzle 140 for printing. The first cooling fan 103 of the reference positioning element blows air onto the heat sink fins to help dissipate heat from the hot end.

[0100] After the printing material is extruded from the nozzle 140 onto the processing platform 400, it can be cooled rapidly to prevent the material from deforming before curing. The printed product cools rapidly to prevent the material from sagging or deforming, thus improving the printing quality.

[0101] Please see Figure 6 The positioning and alignment component of the second device 200 also includes the lower surface 203 of the connecting portion 215, which is aligned with the upper edge of the first cooling fan 103 on the side away from the processing platform 400. When the second device 200 is connected to the first device 100, the first latching portion 220 and the second latching portion 230 of the connecting portion 215 extend into the first limiting groove 120 and the second limiting groove 130, and the lower surface 203 of the connecting portion 215 is aligned with the upper edge of the first cooling fan 103 on the side away from the processing plane, thus aligning the first device 100 and the second device 200. By identifying whether the lower surface 203 of the connecting portion 215 is aligned with the upper edge of the first cooling fan 103 on the side away from the processing plane, it is determined whether the second device 200 is installed in place.

[0102] One of the first device 100 and the second device 200 is a 3D printing head, and the other is a mounting component. The 3D printing head includes a hot end for heating the printing material, and the mounting component includes a connector or a laser head with an output laser. The connector is used to connect a cutter assembly or a pen holder, and the pen holder is used to connect a drawing pen. When the first device 100 is a 3D printing head, the second device 200 is a mounting component. When the second device 200 is a 3D printing head, the first device 100 is a mounting component. When the first device 100 is a 3D printing head and the second device 200 is a mounting component, a laser head can be connected to the 3D printing head, and a connector can also be connected to the 3D printing head. The connector is used to connect the cutter assembly and the pen holder, and the pen holder is used to connect a drawing pen. The type of mounting component on the 3D printing head can be switched. For example, when a laser head is already connected to the 3D printing head, the laser head can be detached and replaced with a connector that can connect to a cutter assembly or a pen holder. When the 3D printing head is already connected to a connector for attaching a cutter assembly or pen holder, this connector can be detached and replaced with a laser head. The hot end of the 3D printing head, used to heat the printing material, extrudes the material through a nozzle. The printing material can be a heat- and melt-friendly plastic filament, such as polylactic acid or acrylonitrile-butadiene-styrene copolymer. The nozzle diameter can be 0.2mm, 0.4mm, or 0.8mm, etc. The printing material contained within the 3D printing head can be of multiple colors and with different properties, not just one type.

[0103] In some feasible implementations, when the 3D printing head is connected to the laser head, after the 3D printing head has finished printing the product or during the printing process, the laser head performs laser engraving on the 3D printed product / part of the product. The high energy density of the laser beam causes the material surface to heat up rapidly, melt, or vaporize, thereby forming the desired pattern or text. This reduces the steps of first installing the 3D printing head, then disassembling it, and then installing the laser head, improving production efficiency. Alternatively, the processing consumables for the laser head, such as acrylic sheets, wood, metal, glass, stainless steel, and rock, can be placed on the processing platform, allowing the laser head to process products other than 3D printed products. The processing equipment of this application can achieve 3D printing independently, laser engraving / cutting independently, or both simultaneously. By sharing the same set of motion devices, such as guide rods / processing platforms, between the laser head and the 3D printing head, various processing methods can be achieved, such as printing, engraving / cutting, printing while engraving / cutting, or printing first and then engraving / cutting, providing multiple possibilities for complex product manufacturing, further improving production efficiency, and reducing costs.

[0104] Sculpting refers to the process of altering the appearance of a material without completely penetrating it. It involves removing portions of a material through carving, engraving, or other methods to create a desired shape, pattern, or design. Examples include carving fine lines and patterns on a material's surface using a carving knife, or engraving text or images on a material's surface using a laser beam.

[0105] Cutting refers to altering the appearance, properties, and / or state of a material by means of mechanical force, heat, water, or chemical methods, separating the material into two or more parts. Cutting can include, for example, through-cutting, bleaching, curing, burning, etc. Examples include mechanical cutting, thermal cutting, water cutting, or chemical cutting.

[0106] When the 3D printing head is connected to the connector, and the connector is connected to the cutter assembly, the cutter assembly is used to cut the 3D printed product / part of the product after printing or during the printing process, removing excess parts of the 3D printed product. Alternatively, the cutter assembly can perform secondary processing on the 3D printed product, cutting it into the required shape. The cutter assembly can be made of high-hardness materials, such as tool steel and hard alloys. The cutter head in the cutter assembly is detachable and can be of various types, such as disc cutter type, pointed cutter type, etc., providing a variety of different cutting methods. Alternatively, the processing consumables of the cutter assembly, such as wood, paper, plastic, leather, metal sheets such as foil, fabric, etc., can be placed on the processing platform, and the cutter assembly can process products other than 3D printed products. The processing equipment of this application can realize 3D printing alone, cutting alone, or both. Cutting can cut some flammable materials such as paper and plastic, compared to laser cutting.

[0107] When the 3D printing head connects to a connector, and the connector connects to a pen holder, the pen can be used for drawing and design on the 3D printed product / part of the product. The pen has an adjustable tip and ink to achieve different drawing effects and precision. The pen is detachably connected to the pen holder, allowing for multi-colored drawing by changing different colored pens, and different pen effects by changing different types of pens. In this application, the connector is compatible with the connection of the cutter assembly and the pen holder. By sharing the same motion device, such as the guide rod / processing platform, with the 3D printing head, various processing methods can be achieved. Furthermore, the connector can connect to cutter assemblies with different cutter types and to pens of different colors / types, allowing for a wide variety of processing methods and greatly enriching the processing forms and efficiency of the processing equipment.

[0108] Optionally, after the 3D print head finishes printing, the product can be further processed using a mounting device. For example, a laser head can perform laser engraving on the product, a cutting assembly can cut it, or a pen can draw patterns on it. This avoids the repeated installation and removal of the 3D print head, laser head, cutting assembly, and pen holder, thus improving the production efficiency of the processing equipment.

[0109] Please see Figure 2The first device 100 has a first socket 112 and a second socket 110. The first socket 112 is used to connect to a power supply or control module via a first cable 111 to supply power to the first device 100 or to transmit motion commands to the first device 100. The second socket 110 is used to connect to a second device 200 via a second cable 210 to supply power to the second device 200 and to transmit motion commands. The first socket 112 and the second socket 110 are spaced apart. The first cable 111 can be a power cable, connecting the first device 100 and the power supply, with the power supply providing power to the first device 100 through the first cable 111. The second cable 210 can also be a power cable, connecting the first device 100 and the second device 200, enabling the first device 100 to supply power to the second device 200 or the second device 200 to draw power from the power supply through the first device 100. The second cable 210 can also be a communication line. The second device 200 can communicate with the first device 100 or, through the first device 100, with the processor of the processing equipment to transmit the status of the second device 200 to the first device 100 / processor of the processing equipment, receive information / instructions from the first device 100, or receive information / instructions from the processor of the processing equipment. For example, the first device 100 transmits motion instructions from an external controller to the second device 200 to control the movement of the connector on the second device 200. For instance, when the second device 200 is a mount connected to a connector or laser head, it controls the cutting motion of the cutter assembly, the drawing motion of the pen, and the laser engraving motion of the laser head. Both the first cable 111 and the second cable 210 are provided with protective sleeves of a certain rigidity to support the first cable 111 and the second cable 210, so that there is a sufficient gap between the first cable 111 and the second cable 210 and the top surface of the first device 100 and the second device 200. This avoids the first cable 111 and the second cable 210 from directly contacting the top surface of the first device 100 and the second device 200 and causing overheating, and also avoids the first cable 111 and the second cable 210 from falling on the first device 100 and the second device 200 and interfering with the movement of the first device 100 and the second device 200.

[0110] For some feasible implementation methods, please refer to Figure 2A cable protection drag chain is provided around the first cable 111, and the cable protection drag chain bends the first cable 111 toward the first device 100 to connect to the first socket 112. This bending connection of the first cable 111 ensures that the first device 100 has sufficient travel in the XY plane. The second socket 110 is located on the other side of the first device 100, and the socket 218 in the second device 200 that connects to the second cable is located on the same side as the second socket 110. For example, socket 218 and the second socket 110 are located on the same side of the first socket 112. When the second cable 210 is located at the bend of the first cable 111 facing the other side of the second device 200, during the process of the first device 100 driving the second device 200, the first cable 111 is dragged and moves together with the first device 100. The first cable 111 is always located to the right of the second cable 210. That is, when the second device 200 is mounted on the first device 100, the second cable 210 connecting the second device 200 and the first device 100 does not cross the first cable 111 that needs to draw power from the power source / communicate with the control module. The connection of the second cable 210 does not interfere with the movement of the first cable 111 and the first device, which can simultaneously ensure the smooth movement and communication of the first device 100 and the second device 200. There is also a certain gap between the first cable 111 and the second cable 210. During the process of the first device 100 driving the second device 200, the first cable 111 and the second cable 210 will not cross or entangle, avoiding interference between the first cable 111 and the second cable 210 during the processing and printing process of the processing equipment. The cable protection cable chain is made of metal materials, such as stainless steel and aluminum alloy. The cable protection cable chain is installed around the first cable 111 to prevent the first device 100 from wearing and twisting the first cable 111 during processing, thereby extending the service life of the first cable 111.

[0111] Please see Figure 5 The 3D printing head includes a sensor 114, and a magnet is provided on the mount. The sensor 114 is used to detect the presence or absence of the mount. The 3D printing head detects the magnet on the mount through the sensor 114 to determine whether the mount is attached to the 3D printing head. When the sensor 114 detects the magnet, it indicates that the 3D printing head is equipped with the mount. At this time, the processing equipment can perform 3D printing operations and also process the 3D printed product. The action commands required by the mount can be transmitted to the mount through the 3D printing head to control the processing of the mount, or the movement of the 3D printing head can be directly controlled. Since the mount is connected to the 3D printing head, the mount will move with the 3D printing head. The relative positional relationship between the two can be calibrated to achieve control of the mount. When the sensor 114 does not detect the magnet, it indicates that the 3D printing head is not equipped with the mount. At this time, the processing equipment can only perform 3D printing operations.

[0112] The 3D print head includes a magnetic cutting device 127 for cutting the printing material. During printing, the 3D print head connects to the printing material, and the hot end of the 3D print head heats and melts the printing material. The melted printing material is then extruded through the nozzle 140 for printing. If the 3D print head needs to change materials during the printing process, it can cut the printing material using the cutting device 127. The 3D print head can also cut or trim the printing material using the cutting device 127 after the printing is complete. For example, if it is necessary to trim an unfinished product during printing, the cutting device 127 can be used to cut the printing material. After the printing is complete, when the processing equipment needs to perform other functions, such as laser engraving, cutting, or drawing patterns, the cutting device 127 can be used to cut the printing material. The cutting device 127 includes a magnetic cutter head. The material of the cutter head is selected according to the specific application scenario and requirements. For example, when the cutting device 127 needs to cut continuously for a long time, a stainless steel or carbide cutter head is used; when cost reduction is required, a carbon steel cutter head is used.

[0113] Sensor 114 can be located near the cutting device 127 and is also used to detect the position of the cutting device 127. The cutting device 127 includes a magnetic cutter head. When the cutting device 127 performs a cutting action, sensor 114 determines the state of the cutting device by detecting the position of the cutter head, such as detecting the position of the cutter head to determine whether the cutting is successful, or to determine whether the cutting device 127 has successfully reset. When sensor 114 detects that the cutting device 127 has not reset, it will issue a prompt. For example, when sensor 114 detects that the cutting device 127 has not reset, the control panel screen of the processing equipment will display a corresponding prompt to inform the operator that the cutting device 127 has not reset. Alternatively, when the first device 100 receives a motion command to perform processing, sensor 114 detects whether the position of the cutting device 127 is processing according to a predetermined trajectory. When the motion trajectory of the cutting device 127 detected by sensor 114 does not match the motion trajectory required by the actual motion command, the control panel screen of the processing equipment will display a corresponding prompt to inform the operator that the motion trajectory of the cutting device 127 is incorrect.

[0114] In some feasible implementations, the magnets on the laser head and the connector have opposite magnetic properties. The mount can be either a laser head or a connector. The magnetic poles of the magnet facing the sensing surface of the laser head and the magnet facing the sensing surface of the connector have opposite magnetic properties, allowing the sensor 114 of the 3D printing head to distinguish between the laser head and the connector. For example, when the magnetic pole of the magnet facing the sensing surface of the laser head is the N pole, the magnetic pole of the magnet facing the sensing surface of the connector is the S pole. When the sensor 114 detects that the magnetic pole of the magnet facing the sensing surface is the N pole, it indicates that the mount connected to the 3D printing head is the laser head; when the sensor 114 detects that the magnetic pole of the magnet facing the sensing surface is the S pole, the mount connected to the 3D printing head is the connector.

[0115] Please see Figure 8 When the second device 200 is a laser head 201, the exit of the 3D printing head nozzle 140 is lower than the lower surface of the laser head 201. When the 3D printing head is printing, the printing material is heated and melted by the hot end, then extruded through the nozzle 140 for printing. The lower exit of the nozzle 140 ensures that the 3D printing head will not be obstructed even with the laser head 201 installed, avoiding motion interference from the laser head 201. The exit of the nozzle 140 is 1mm-2mm lower than the lower surface of the laser head 201. In this application, the exit of the 3D printing head nozzle 140 is 1.6mm lower than the lower surface of the laser head 201, allowing the processing equipment to perform laser engraving simultaneously with 3D printing, meeting the scenario of simultaneous printing and engraving. Simultaneously, the laser head 201 does not obstruct the 3D printing head's printing, avoiding motion interference from the laser head 201.

[0116] Please see Figure 9 When the second device is a connector 500, the connector 500 connects to a cutting assembly or a pen holder for connecting a pen. The cutting head of the cutting assembly or the pen tip of the pen is lower than the nozzle 140 of the 3D printing head. When processing the product, the cutting head of the cutting assembly or the pen tip of the pen must directly contact the product for processing. The cutting head of the cutting assembly or the pen tip of the pen must be lower than the nozzle 140 of the 3D printing head to ensure that the processing equipment can perform cutting or drawing. At the same time, the 3D printing head will not obstruct the operation of the cutting head of the cutting assembly or the pen tip of the pen, avoiding motion interference between the 3D printing head and the cutting head / pen tip. In some feasible embodiments, the cutting head / pen tip can be retracted in the working device of the 3D printing head to avoid interference between the cutting head / pen tip and the movement of the 3D printing head. When cutting / drawing is required, the cutting head / pen tip is exposed for processing, and the processing equipment can still achieve 3D printing and cutting / drawing.

[0117] Please see Figure 10The connector 500 has a through hole 509 for the cutter assembly 502 or the pen holder 503 to pass through. The cutter assembly 502 is provided with a magnet 504, or the pen holder 503 has a magnet 512 at one end extending into the connector 500. The connector 500 also has a cavity 507, within which a floating seat 505 is disposed, slidingly contacting the inner wall of the cavity 507. The floating seat 505 is detachably connected to the cutter assembly 502 or the pen holder 503. The floating seat 505 allows the cutter assembly 502 or the pen holder 503 to move up and down along the Z-axis. For example, during the 3D printing process, the cutter assembly 502 or the pen holder 503 can move upward along the Z-axis, thereby not interfering with the operation of the 3D printing head. When the cutter assembly 502 or the pen holder 503 is connected to the pen, the floating seat 505 ensures that the cutter head or pen head and the object to be processed are non-rigidly connected when the cutter head or pen head of the cutter assembly 502 or the pen head of the pen contact the object to be processed.

[0118] A floating elastic element 506 is provided inside the cavity 507. A floating seat 505 is connected to the floating elastic element 506 in the axial direction of the through hole 509. A sensor 114 on the connector is located near the cutter assembly magnet 504 or the pen holder magnet 512 to detect whether the connector 500 is connected to the cutter assembly 502 or the pen holder 503. The floating seat 505 is fixedly connected to the cutter assembly 502 or the pen holder 503. The floating seat 505 is connected to the floating elastic element 506 in the cavity in the axial direction of the through hole 509, allowing the cutter assembly 502 or the pen holder 503 to move up and down relative to the connector 500 along the Z-axis.

[0119] Sensor 114 can also be disposed on the main board 508 of connector 500. Main board 508 is mounted near magnet 504 on cutter assembly or magnet 512 on pen holder. In this application, sensor 114 is a Hall sensor or eddy current coil capable of identifying magnet 504 on cutter assembly or magnet 512 on pen holder. In some feasible embodiments, the magnetic polarities of magnet 504 on cutter assembly and magnet on pen holder are different. Then, Hall sensor or eddy current coil can detect the magnetic polarity of magnet 504 on cutter assembly or magnet 512 on pen holder to determine whether connector 500 is connected to cutter assembly 502 or pen holder 503. A Hall sensor or eddy current coil can detect the magnetic field strength of the magnet 504 on the cutter assembly or the magnet 512 on the pen holder. This magnetic field strength is positively correlated with the distance between the magnet 504 on the cutter assembly or the magnet 512 on the pen holder and the Hall sensor or eddy current coil. The Hall sensor or eddy current coil can determine whether the cutter assembly 502 or the pen holder 503 is properly installed based on the magnetic field strength. Optionally, the Hall sensor or eddy current coil can also determine the movement trajectory of the cutter assembly 502 or the pen holder 503, thereby determining whether the cutter assembly 502 or the pen holder 503 moves along a specified trajectory. The sensor 114 is mounted on the main board 508, reducing the need for a separate mounting plate for the sensor 114, simplifying the mechanical structure, and reducing installation space and production costs.

[0120] Please see Figure 11 The cutting assembly 502 includes a blade head 511 and a blade holder 510, with a pen holder 503 for attaching a pen. A magnet 504 is provided on the blade holder 510 of the cutting assembly 502. The blade head 511 and blade holder 510 of the cutting assembly 502 can be an integral structure, or they can be separate structures. When the blade holder 510 and blade head 511 are separate structures, the blade head 511 is first inserted into the blade holder 510, and then the blade holder 510 is connected to the connector 500. The blade head 511 is detachably connected to the blade holder 510, and various different cutting methods can be achieved by replacing the blade head 511.

[0121] Please see Figure 12A magnet 512 is provided at one end of the pen holder 503. The magnet 512 on the pen holder 503 and the magnet 504 on the cutter assembly 502 have opposite magnetic properties. The sensor 114 is also used to determine whether the connector 500 is connected to the cutter assembly 502 or the pen holder 503 by identifying the magnetic properties of the magnet on the connector 500. For example, the magnetic pole of the magnet 504 on the cutter assembly 502 facing the sensor 114 is the N pole, and the magnetic pole of the magnet 512 on the pen holder 503 facing the sensor 114 is the S pole. When the sensor 114 detects the N pole, it determines that the connector 500 is connected to the cutter assembly 502; when the sensor 114 detects the S pole, it determines that the connector 500 is connected to the pen holder 503. Sensor 114 determines whether the 3D printing head is equipped with a cutter assembly 502 or a connected pen holder 503 by sensing the magnetic polarity of the magnet 504 on the cutter assembly or the magnet 512 on the pen holder, so that the processing movement between the 3D printing head and the cutter assembly 502 or pen holder 503 is better matched, and damage to the product is avoided by the 3D printing head and the cutter assembly 502 or pen holder 503.

[0122] The sensor 114 is fixed relative to the connector 500, while the cutter assembly 502 or pen holder 503 is movably mounted on the connector 500. The sensor 114 also detects the magnetic field strength of the magnet 504 on the cutter assembly or the magnet 512 on the pen holder to determine the position of the cutter assembly 502 or the pen holder 503. When the pen connected to the cutter assembly 502 or the pen holder 503 processes the product, the magnetic field strength of the magnet 504 on the cutter assembly 502 changes with the movement of the cutter assembly 502, and the magnetic field strength of the magnet 504 on the pen holder 503 changes with the movement of the pen. The sensor 114 detects and records the magnetic field strength of the magnet 504 on the cutter assembly or the magnet 512 on the pen holder, and determines the positional change of the cutter assembly 502 or the pen holder 503 based on the change in the magnetic field strength of the magnet 504 on the cutter assembly 502 or the magnet 504 on the pen holder 503, thereby determining the movement trajectory of the cutter assembly 502 or the pen.

[0123] In this application, both the cutter assembly 502 and the pen holder 503 are cylindrical, which facilitates their insertion into the connector 500, shortens the installation time, and improves work efficiency. The magnet 504 on the cutter assembly or the magnet 512 on the pen holder can be annular and positioned at one end of the cutter assembly 502 or the pen holder 503. When the cutter assembly 502 or the pen holder 503 is connected to the connector 500, the sensor 114 can detect the magnet 504 on the cutter assembly or the magnet 512 on the pen holder without needing to adjust its position, facilitating the sensor 114's identification of the magnet 504 on the cutter assembly 502 or the magnet 512 on the pen holder 503.

[0124] When the first device 100 is a 3D printing head and the second device 200 is a connector 500, the magnetic polarities of the magnet 504 on the cutter assembly or the magnet 512 on the pen holder connected to the connector 500 are different. The sensor 114 determines whether the connector 500 is connected to the cutter assembly 502 or the pen holder 503 by sensing the magnetic polarity of the magnet 504 on the cutter assembly or the magnet 512 on the pen holder, so that the movement of the 3D printing head and the connector 500 is matched, thus improving the matching degree between the 3D printing head and the connector 500 during processing and production. In this application, the structure and position of the sensor 114 and the magnet on the connector 500 are relatively simple. The sensor 114 is set on the mainboard 508, saving installation space and reducing production costs.

[0125] Please see Figure 13 The laser head 201 includes a second cooling fan 274, a heat sink 280, an air collecting nozzle 245, an air duct channel 272, an engraving laser 273, a housing 270, and a concentrator 240. The housing 270 is connected to the concentrator 240. The heat sink 280 and the second cooling fan 274 are housed within the housing 270. The heat sink 280 and the engraving laser 273 are positioned between the second cooling fan 274 and the concentrator 240, with the heat sink 280 contacting the engraving laser 273. The housing 270 protects the internal structure of the laser head 201. The concentrator 240 concentrates airflow, using this concentrated airflow to blow away smoke / debris generated during laser engraving from the working area, preventing this smoke from entering the laser head and affecting the laser engraving process. The concentrator 240 also provides mounting locations for other components of the laser head 201. The heat sink 280 and the second cooling fan 274 dissipate heat from the engraving laser 273; the second cooling fan 274 blows air towards the heat sink 280 to accelerate heat dissipation. In this application, the heat sink 280 contacts the engraving laser 273, and the heat from the engraving laser 273 can be directly conducted to the heat sink 280. The heat sink 280 and the engraving laser 273 can be connected via a metal heat-conducting plate 276, allowing the heat generated by the engraving laser 273 to be transferred to the heat sink 280 through the metal heat-conducting plate 276, increasing the heat dissipation area of ​​the engraving laser and accelerating its heat dissipation rate. A second cooling fan 274 is positioned above the heat sink 280 and the engraving laser 273. When the laser head 201 starts working, the engraving laser 273 is emitted through the laser exit port to perform laser engraving on the product to be processed. At this time, the heat generated by the engraving laser 273 is transferred to the heat sink 280 through the metal heat-conducting plate 276. The second cooling fan 274 blows air onto the heat sink 281, and the air blown by the second cooling fan 274 passes through the heat sink 280 and is discharged from the outlet of the air shroud 240, transferring the heat from the heat sink 280 away.

[0126] The air duct channel 272 is located on the other side of the engraving laser 273 away from the heat sink 280. An air pump is connected to it. When the engraving laser 273 is working, the air pump connected to the air duct channel 272 works, forming a downward airflow in the air duct channel 272. The airflow blows the smoke / debris generated by the laser engraving away from the working area through the air collecting nozzle 245, preventing the smoke / debris from entering the engraving laser and the laser head and affecting the laser engraving.

[0127] Please see Figure 14 When the second device 200 is a laser head 201, the processing equipment is also equipped with an air pipe 211. The second device 200 is equipped with an air pipe connector 219. One end of the air pipe 211 is connected to the air pipe connector 219 along the cable protection drag chain, and the other end of the air pipe 211 is used to connect to an air pump. The air pipe 211 is used to connect the external air pump and the air pipe channel 272 inside the laser head 201. When the laser head 201 performs laser engraving, the external air pump works, and blows the smoke generated by laser engraving away from the working area through the air pipe 211, the air pipe channel 272, and the air collecting nozzle 245, preventing this smoke from entering the engraving laser and affecting the laser engraving. The laser head 201 can engrave accurately. In this application, the air pipe 211 is made of a highly flexible material, such as polyurethane and polyethylene, so that when the air pipe 211 is connected to the air pipe connector 219 along the cable protection drag chain of the first cable 111, the air pipe 211 can bend with the bending of the first cable 111, improving the neatness of the internal pipeline of the processing equipment. When the second device 200 is the cutter assembly 502, the air pipe 211 can also be used to connect the air pipe channel 272 inside the cutter assembly 502 to transmit compressed air and blow the waste generated after the cutter assembly 502 cuts the product away from the processing area to avoid the waste from affecting the cutting process.

[0128] Please see Figure 14 In the second device 200, the connector 218 for connecting the second cable and the air hose connector 219 are arranged horizontally along the depth direction of the second device 200, which is the Y-axis direction. The air hose connector 219 and the second connector 110 are located on the same side of the cable protection drag chain. The air hose connector 219 of the second device 200 is located in the direction from the first connector 112 extending from the first device 100 to the second device 200, allowing the air hose 211 to extend directly along the cable protection drag chain of the first cable 111 to the second device 200. Simultaneously, the connector 218 for connecting the second cable and the air hose connector 219 in the second device 200 are arranged horizontally along the depth direction of the second device 200. The second cable 210 is located on the side of the air hose 211 that bends towards the first device 100. During the process of the first device 100 driving the second device 200, the air hose 211 and the second cable 210 will not cross or become entangled, avoiding motion interference between the first cable 111 and the second cable 210 during processing and printing in the processing equipment.

[0129] Please see Figure 15 The connector 218 for connecting the second cable and the endotracheal connector 219 in the second device 200 can also be arranged front-to-back along the length of the second device 200, which is the X-axis direction. The second device 200 is mounted on the first device along the Y-axis direction, with the connector 218 and the endotracheal connector 219 positioned left-to-right relative to the direction in which the second device is mounted on the first device. The endotracheal connector 219 has a bend, which is a flexible, rotatable endotracheal connector. The connector 218 for connecting the second cable and the endotracheal connector 219 in the second device 200 can be arranged front-to-back along the length of the second device 200, and the endotracheal connector 219 and the second connector 110 are located on the same side. The endotracheal connector 219 is located on the side of the connector 218 of the second device 200 that connects the second cable, facing the second connector 110. In the X-axis direction, the endotracheal connector 219 and the connector 218 of the second device 200 are on the same straight line. The overall height of the air hose connector 219 is lower than that of the second cable 210. When the air hose 211 is connected to the air hose connector 219 on the second device 200 along the cable protection cable chain, the height of the air hose 211 is reduced, thereby reducing the overall height of the first device 100 and the second device 200, and reducing the storage space required for the first device 100 and the second device 200 to be installed in the processing equipment. The bendable air hose connector controls the bend of the air hose when it enters the second device 200, so that there is a certain gap between the air hose 211 and the top surfaces of the first device 100 and the second device, avoiding interference between the air hose 211 and the first device 100 and the second device 200 during operation. At the same time, the rotatable bendable air hose connector allows the air hose 211 to rotate within a certain range, ensuring that there is sufficient adjustment space when the air hose 211 is connected to the second device 200 along the cable protection cable chain. The direction of the elbow opening of the air hose connector 219 is adjusted according to the installation. For example, the elbow opening faces the direction from the second cable 210 to the first cable 111, and one end of the air hose 211 is connected to the air hose connector 219 along the cable protection cable chain. When the air hose 211 is connected along the cable protection cable chain, the elbow opening of the air hose connector 219 faces the Y-axis direction, so that when the air hose 211 is connected to the air hose connector 219 from above the first socket 112 along the cable protection cable chain, the air hose 211 and the second cable 210 will not cross or entangle, thus avoiding motion interference. The elbow of the air hose connector 219 adopts a compression fitting installation. When the air hose 211 is connected to the elbow of the air hose connector 219, the air hose 211 is directly fitted onto the elbow, which facilitates the installation and removal of the air hose 211.

[0130] A funnel-shaped air collector 245 is positioned below the engraving laser 273. One end of the air pipe channel 272 connects to the air pipe 211 for connecting to the air pump, while the other end connects to the air collector 245. During laser engraving, the air pump, air pipe 211, air pipe channel 272, and air collector 245 work together. The air pump outputs airflow, which, after passing through the air pipe 211 and air pipe channel 272, creates positive pressure at the air collector 245, blowing away the smoke / debris generated during laser engraving from the working area. This prevents the smoke / debris from entering the engraving laser 273 and laser head 201, thus affecting the quality of the laser engraving. The air collector 245 can employ a multi-hole design, evenly distributing airflow through multiple small holes to ensure that smoke is more effectively blown away from the working area. The air collector 245 can be made of metal, such as stainless steel or aluminum alloy, to ensure its durability and corrosion resistance.

[0131] Please see Figure 13 A protective mirror 275 is provided between the gas collector 245 and the engraving laser 273. Dust, smoke, and debris generated during laser engraving by the laser head 201 may adhere to the optical components of the engraving laser 273, such as lenses and mirrors, leading to reduced laser beam transmission efficiency or even damage to the optical components. The protective mirror 275, located between the gas collector 245 and the engraving laser 273, acts as the first line of defense, preventing these contaminants from entering the optical system. The protective mirror 275 is made of high-strength, wear-resistant materials, such as quartz glass or sapphire glass. In this application, when the laser head 201 is not equipped with the air duct channel 272, the air blown by the second cooling fan 274 can also be used to create positive pressure at the laser exit port, preventing debris generated during laser engraving from adhering to the protective mirror 275 and extending the service life of the protective mirror 275.

[0132] Please see Figure 13The gas collecting nozzle 245 includes a hollow fixing part 246 and a hollow protrusion 247. The fixing part 246 is connected to the protrusion 247. The fixing part 246 of the gas collecting nozzle 245 is connected to the air concentrator 240 via a pipe thread, wherein the fixing part 246 has an external thread, and the air concentrator 240 has an internal thread. The gas collecting nozzle 245 can be removed from the air concentrator 240, thereby removing the entire gas collecting nozzle 245 from the laser head 201. The air concentrator 240 absorbs part of the height of the gas collecting nozzle, reducing the overall height of the laser head. In this application, the dimension of the gas collecting nozzle 245 along the height direction is between 17.19mm and 21.01mm, and the gas collecting nozzle 245 is completely housed in the air concentrator 240. For example, the engraving laser uses an engraving laser with a focal length of 40mm, that is, the distance from the laser exit port of the engraving laser 273 to the surface of the processed product is 40mm. The distance from the focal point of the engraving laser 273 to the bottom surface of the nozzle 140 of the 3D printing head is 20.9mm, which can meet various scenarios where the laser is not planar, such as printing bowls or plates with large curved surfaces. In this case, the distance from the engraving laser outlet to the bottom surface of the nozzle 140 of the 3D printing head is 19.1mm. Within this 19.1mm height dimension, an air collector 245 needs to be installed. Adding the 1.6mm margin that the nozzle 140 of the 3D printing head has below the bottom surface of the laser head 201, the air collector 245, with a size between 17.19mm and 21.01mm, will not interfere with the movement of the 3D printing head while not exceeding the height dimension.

[0133] Please see Figure 8 A second camera 104 is provided on the 3D printing head, and a line laser is provided on the laser head 201. The emission direction of the line laser forms an angle with the optical axis of the second camera 104, and the axial direction of the optical axis of the second camera 104 is parallel to the height direction of the laser head 201. In this application, a line laser head 204 is provided on one side of the laser head 201. The line laser head 204 emits an oblique line laser, and the focal point of the oblique line laser falls within the field of view of the second camera 104. The second camera 104 is used to measure the height between the 3D printing head and the processing platform 400. The focal length of the line laser is at the same height as the focal point of the engraving laser 273, so that after the height between the 3D printing head and the processing platform 400 is measured, the engraving laser 273 quickly moves to the height to be engraved without requiring the laser head 201 to prepare again. This improves the working efficiency of the processing equipment and avoids repeated raising and lowering of the laser head 201 or the processing platform 400.

[0134] Please see Figure 16The laser head 201 includes a PCB board 205 with components mounted on it. The PCB board 205 is placed along the height of the heat sink 280, with the side of the PCB board 205 containing the components facing the heat sink 280. The heat sink 280 has a limiting groove to accommodate the height of the components. A limiting groove is also provided on the side of the heat sink 280 facing away from the engraving laser 273 to limit the position of the PCB board 205, thus fixing the PCB board 205 to the heat sink 280. Simultaneously, the heat generated by the components on the PCB board 205 during operation is transferred to the heat sink 280 via the limiting groove for dissipation. Placing the components on the PCB board 205 facing the heat sink 280 avoids the components, especially electrolytic capacitors, occupying the width of the laser head. This is particularly beneficial in high-power engraving laser applications where the laser die requires significant space, allowing the laser head 201 to maintain a compact structure, making it lightweight and easy to control.

[0135] In this application, the PCB board 205 containing the components may be equipped with a light strip with multiple LEDs. The light strip is used to indicate the working status of the laser head 201 through light signals. For example, a red light strip indicates that the laser head 201 is connected to the power supply, a yellow light strip indicates that the laser head 201 is in standby mode, a green light strip indicates that the laser head 201 is in working mode, and an off light strip indicates that the laser head 201 is not connected to the power supply.

[0136] Please see Figure 16 Multiple heat sinks 281 are spaced apart on the heat sink 280, and multiple air ducts 282 are formed between the spaced heat sinks 281 and the air duct 240. The spaced space between the multiple heat sinks 281 on the heat sink 280 forms the air duct 282 of the heat sink 280. The air ducts 282 and heat sinks 281 on the heat sink 280 are a compact integrated structure, reducing the production cost of the second device 200. The heat sinks 281 are made of high thermal conductivity materials, such as aluminum, copper, or aluminum alloy, so that heat can be quickly transferred from the engraving laser 273 to the surface of the heat sink 281. The air ducts 282 formed by the spaced heat sinks 281 are connected to the air duct 240, so that the upper and lower air inside the laser head 201 housing 270 can be convected. The second cooling fan 274 blows air onto the heat sinks 281, accelerating the airflow on the surface of the heat sinks 281, increasing air turbulence, and improving the convective heat dissipation efficiency.

[0137] Please see Figure 8The air-concentrating shield 240 gradually narrows away from the engraving laser 273. After the inlet of the air-concentrating shield 240 connects with the air duct 282, the air duct 282 guides the airflow to exit from the outlet of the air-concentrating shield 240 away from the engraving laser 273. At the narrowing point of the air-concentrating shield 240, the outlet surface and the side surface of the air-concentrating shield 240 form an obtuse angle, making the air-concentrating shield 240 more focused on the airflow. After the inlet of the air-concentrating shield 240 connects with the air duct 282, the air duct 282 guides the airflow to exit from the outlet of the air-concentrating shield 240 away from the engraving laser 273. The cross-sectional area at the outlet of the air-concentrating shield 240 is smaller than that at the inlet, increasing the airflow velocity and improving the heat dissipation efficiency of the laser head 201.

[0138] Please see Figure 17 The wind concentrator 240 includes an air nozzle mounting part 241, a cover body 242, and a sensor mounting part 243. The air nozzle mounting part 241 is connected to the cover body 242, and the sensor mounting part 243 is connected to the air nozzle mounting part 241. A sensor is provided on the sensor mounting part 243. The air nozzle mounting part 241 is used to connect an air nozzle 245. The cover body 242 surrounds the air nozzle mounting part 241 and is connected to it. The cover body 242 is connected to the housing 270. The cover body 242 gradually narrows in the direction away from the engraving laser 273. The inner surface of the cover body 242 forms an angle with the wind concentrator 240. For example, the angle between the inner surface of the cover body 242 and the height direction of the wind concentrator 240 is between 30° and 38°, making the wind concentrator 240 more focused on airflow. The air collecting nozzle mounting part 241 of the air collecting cover 240 is used to connect the air collecting nozzle 245, so that the air collecting nozzle 245 is positioned with the air collecting cover 240, and at the same time, it ensures that the engraving laser 273 can be emitted from the air collecting nozzle 245 to perform laser engraving on the product.

[0139] The sensor mounted on the sensor mounting section 243 is used to detect the distance between the laser head 201 and the processed product. The processing equipment adjusts the processing distance between the laser head 201 and the processed product by analyzing the distance detected by the sensor from the gas collector mounting section 241 to the processed product. In this application, the sensor mounted on the sensor mounting section 243 is an infrared sensor for detecting distance. The sensor mounted on the sensor mounting section 243 also includes sensors for detecting temperature and flame. These sensors detect the temperature generated by the laser head 201 during processing. When the temperature generated by the laser head 201 during processing exceeds the safe temperature, the second device 200 is controlled to suspend operation. When the sensor detects that the flame temperature generated during processing exceeds the safe value, the second device 200 is controlled to suspend operation. In this application, the sensors for detecting temperature and flame are NTC (Negative Temperature Coefficient) sensors, and the NTC sensors are mounted on the sensor mounting section 243 of the gas collector shroud 240. During processing with laser head 201, the NTC sensor detects the temperature of the lower surface of laser head 201 and transmits the temperature value to the processor. When the temperature exceeds the set value, the processor controls laser head 201 to pause operation. If a flame is generated by laser head 201 during processing, the NTC sensor detects the flame temperature. When the NTC sensor detects that the flame temperature exceeds the safe value, it transmits a signal to the processor, which then controls laser head 201 to pause operation. The processor is located inside laser head 201 or within the processing equipment.

[0140] The cover 242 is connected to the housing 270, integrating the air-concentrating cover 240 with the housing 270, thus protecting the equipment inside the laser head 201 together. The cover 242 gradually narrows away from the engraving laser 273, making the cross-sectional area at the outlet of the air-concentrating cover 240 smaller than that at the inlet. At the narrowing point of the air-concentrating cover 240, the smaller cross-sectional area at the outlet increases the airflow velocity and improves the heat dissipation efficiency of the laser head. At the narrowing point of the air-concentrating cover 240, the outlet surface and the side surface of the air-concentrating cover 240 form an obtuse angle, making the air-concentrating cover 240 more focused on airflow.

[0141] Please see Figure 18 The processing equipment provided in this application determines the mounting status or type of the mounting component by identifying the magnetic polarity of the magnet on the mounting component. The steps include:

[0142] Step S101: Obtain the magnetic polarity of the magnet in the second device 200 attached to the first device 100; wherein the magnetic polarity of the magnet on the laser head 201 is different from that of the magnet on the connector 500. The first device 100 is equipped with a sensor, and the second device 200 is equipped with a magnet. The sensor identifies the magnetic polarity of the magnet in the second device 200 attached to the first device 100. In this application, when the first device 100 is a 3D printing head, the second device 200 is either the laser head 201 or the connector 500. The magnetic polarity of the magnet on the laser head 201 is different from that of the magnet on the connector 500. The sensor determines whether the magnet attached to the 3D printing head is the connector 500 or the laser head 201 by identifying the magnetic polarity of the magnet in the second device 200.

[0143] Step S102: Based on the magnetic polarity of the magnet in the second device 200, at least one of the mounting state and type of the second device 200 is obtained. The sensor on the first device 100 determines the mounting state and type of the second device 200 mounted on the first device 100 by sensing the magnetic pole of the magnet on the second device 200 facing the sensor. For example, if the magnet on the connector 500 has a north pole facing the sensor, and the magnet on the laser head 201 has a south pole facing the sensor, when the sensor detects the north pole, it is determined that the first device 100 is mounted on the connector 500; when the sensor detects the south pole, it is determined that the first device 100 is mounted on the laser head 201. The sensor determines whether the second device 200 is connected to the laser head 201 or the connector 500 by identifying the magnetic polarity of the magnet. This determines the actions that the second device 200 and the first device 100 can perform. For example, when the sensor determines that the first device 100 is connected to the laser head 201, laser engraving can be performed on the product processed by the first device 100 after processing. When the sensor determines that the first device 100 is connected to the connector 500, cutting or pattern drawing can be performed on the product processed by the first device 100 after processing. This improves the matching degree between the first device 100 and the second device 200 and avoids damage to the product caused by the mismatch between the first device 100 and the second device 200.

[0144] When the sensor detects that the first device 100 is connected to the connector 500, the connector 500 is connected to a pen and a cutter assembly 502. The pen is connected to the connector via a pen holder, which has a magnet 512, and the cutter assembly 502 has a magnet 504. The magnet 512 on the pen holder and the magnet 504 on the cutter assembly 502 have different magnetic polarities. The first device determines whether the second device connected to it is the pen or the cutter assembly 502 by detecting the magnetic polarity of the magnet 512 on the pen holder or the magnet 504 on the cutter assembly 502.

[0145] Please see Figure 19 In the processing equipment provided in this application, the first device 100 obtains the identity information of the second device 200 through the second cable 210, and determines whether the first device 100 is equipped with a laser head 201 or a connector 500. The steps include:

[0146] Step S111: Obtain the identity information of the second device 200 via cable; the identity information includes a first identifier of the laser head 201 or a second identifier of the connector 500. When the second device 200 is attached to the first device 100, the first device 100 and the second device 200 communicate via the second cable 210. The second device 200 is connected to either the laser head 201 or the connector 500. The laser head 201 and the connector 500 have corresponding identifiers. The identifier corresponding to the laser head 201 is the first identifier, and the identifier corresponding to the connector 500 is the second identifier. The identity information of the second device 200 includes the first identifier of the laser head 201 and the second identifier of the connector 500. The first device 100 obtains the identity information of the second device 200 via the second cable 210, identifies the identifiers in the identity information, and determines whether the second device 200 is connected to the connector 500 or the laser head 201. The first device 100 can also transmit motion commands to the second device 200 via the second cable to control the movement of the second device 200. When the second device 200 is connected to the first device 100, the first device 100 can also supply power to the second device 200 through the second cable 210.

[0147] Step S112: Based on the identity information, the second device 200 is identified as either the laser head 201 or the connector 500. The first device 100 obtains the identity information of the second device 200 through a cable and identifies the first identifier and the second identifier in the second device 200. When the first device 100 identifies the first identifier, it determines that the second device 200 connected to the first device 100 is the laser head 201; when the first device 100 identifies the second identifier, it determines that the second device 200 connected to the first device 100 is the connector 500; when the first device 100 does not identify the first identifier and the second identifier, it determines that the first device 100 is not connected to either the laser head 201 or the connector 500. The first device 100 determines whether the first device 100 is equipped with a laser head 201 or a connector 500 by obtaining the identity information of the second device 200 through the second cable 210, and then determines the type of processing that the first device 100 and the second device 200 can perform. For example, the first device 100 is a 3D printing head, and the second device 200 is either a laser head 201 or a connector 500. The 3D printing head obtains and identifies the identity information of the second device 200 through the second cable 210.

[0148] When the 3D print head confirms that it is equipped with the laser head 201, after the 3D print head has finished printing the product or during the printing process, the laser head 201 performs laser engraving on the 3D printed product / part of the product. The high energy density of the laser beam causes the material surface to heat up rapidly, melt, or vaporize, thereby forming the desired pattern or text. This reduces the steps of first installing the 3D print head, then removing the 3D print head, and then installing the laser head 201, thus improving production efficiency. Alternatively, the processing consumables of the laser head 201, such as acrylic sheets, wood, metal, glass, stainless steel, rock, etc., can be placed on the processing platform, and the laser head 201 can process products other than 3D printed products. The processing equipment of this application can realize 3D printing alone, laser engraving / cutting alone, or both 3D printing and laser engraving / cutting. By sharing the same motion mechanism, such as guide rods / processing platforms, with the laser head 201 and the 3D printing head, various processing methods can be achieved, such as printing, engraving / cutting, printing while engraving / cutting, and printing first and then engraving / cutting. This provides multiple possibilities for the manufacturing of complex products, further improving production efficiency and reducing costs.

[0149] When the 3D printing head is confirmed to be mounted with connector 500, and connector 500 is connected to the cutter assembly, the cutter assembly is used to cut the 3D printed product / part of the product after printing or during the printing process, removing excess parts of the 3D printed product. Alternatively, the cutter assembly can perform secondary processing on the 3D printed product, cutting it into the required shape. The cutter assembly can be made of high-hardness materials, such as tool steel and hard alloys. The cutter head in the cutter assembly is detachable and can have various types, such as disc cutter type and pointed cutter type, providing various different cutting methods. Alternatively, the processing consumables of the cutter assembly, such as wood, paper, plastic, leather, metal sheets (such as foil), and fabric, can be placed on the processing platform, and the cutter assembly can process products other than 3D printed products. The processing equipment of this application can realize 3D printing alone, 3D cutting alone, or both. Compared with laser cutting, 3D cutting can cut some flammable materials such as paper and plastic.

[0150] When the 3D printing head is confirmed to be equipped with connector 500, and the connector is connected to the pen holder, the pen can be used for drawing and design on the 3D printed product / part of the product. The pen has an adjustable tip and ink to achieve different drawing effects and precision. The pen is detachably connected to the pen holder, allowing for multi-colored drawing by changing different colored pens, and different pen effects by changing different types of pens. In this application, the connector is compatible with the connection of the cutter assembly and the pen holder. By sharing the same motion device, such as the guide rod / processing platform, with the 3D printing head, various processing methods can be achieved. Furthermore, the connector can connect to cutter assemblies with different cutter types and pens of different colors / types, allowing for a wide variety of processing methods and greatly enriching the processing forms and efficiency of the processing equipment.

[0151] Optionally, after the 3D print head finishes printing the product, it can be further processed using a mounting component. For example, the laser head 201 can perform laser engraving on the 3D print head, the cutting assembly can cut the 3D print head, or a pen can draw patterns on the 3D print head. This avoids the repeated installation and removal of the 3D print head, laser head 201, cutting assembly, and pen holder, thus improving the production efficiency of the processing equipment.

[0152] Please see Figure 20 The method steps for the first device to determine whether the second device attached to the first device is connected to the pen or the cutter assembly by detecting the magnetic polarity of the magnet on the pen holder or the cutter assembly include:

[0153] Step S121: If the second device is a connector, detect the magnetic polarity of the magnet connected to the connector.

[0154] Step S122: Based on the magnetic polarity of the magnet connected to the connector, it is determined that the connector is connected to a pen or cutter assembly.

[0155] When the second device is a connector, a cutter assembly or a pen is connected to the connector via a pen holder. Both the pen holder and the cutter assembly have magnets. The magnetic polarity of the magnet on the pen holder facing the sensor of the first device is opposite to the magnetic polarity of the magnet on the cutter assembly facing the sensor of the first device. The first device determines whether the connector is connected to the pen holder or the cutter assembly by detecting the magnetic polarity of the magnets in the connector. For example, the magnet on the pen holder has a north pole (N) facing the sensor, and the magnet on the cutter assembly has a south pole (S). When the sensor detects the north pole, the connector is connected to the pen; when the sensor detects the south pole, the connector is connected to the cutter assembly. The first device detects whether the connector is connected to the pen or the cutter assembly by the magnetic polarity of the magnets in the connector. When the first device is equipped with a pen, the pen can be used for drawing and design on the 3D printed product / part of the product. The pen has an adjustable tip and ink to achieve different drawing effects and precision. The paintbrush is detachably connected to a pen holder, allowing for colorful painting by changing different colors and achieving different effects by switching brush types. When the first device is equipped with a cutter assembly, the cutter assembly is used to cut the 3D-printed product / part of the product after printing or during the printing process, removing excess parts. Alternatively, the cutter assembly can perform secondary processing on the 3D-printed product, cutting it into the desired shape. The cutter assembly can be made of high-hardness materials, such as tool steel and hard alloys. The cutter head is detachable and can be of various types, such as disc cutters and pointed cutters, providing multiple cutting methods. Alternatively, materials such as wood, paper, plastic, leather, metal sheets (e.g., foil), and fabric can be placed on the processing platform, allowing the cutter assembly to process products other than 3D-printed ones. In this application, the connector can be compatible with the connection of the cutter assembly and the pen holder. By sharing the same set of motion devices, such as guide rods / processing platforms, with the 3D printing head, a variety of different processing methods can be realized. The connector can also connect to cutter assemblies with different cutter types and to pens of different colors / types, which can be combined to create a variety of processing methods, greatly enriching the processing forms and processing efficiency of the processing equipment.

[0156] For some feasible implementation methods, please refer to Figure 21 The mechanical connection between the first and second devices can be determined by detecting the magnetic field strength of the magnet. The steps may include:

[0157] Step S131: Detect the magnetic field strength of the magnet in the second device. In this application, the magnetic field strength of the magnet in the second device is detected by a sensor in the first device. For example, the sensor in the first device is a Hall effect sensor / eddy current coil. Exemplarily, the Hall effect sensor is placed in the magnetic field generated by the magnet, energized, and the voltage difference across the Hall sensor is measured. The magnetic field strength is calculated based on the Hall coefficient and the current.

[0158] Step S132: If the magnetic field strength of the magnet in the second device is greater than a first preset threshold, it is determined that the mechanical connection of the second device is normal. When the mechanical connection between the second device and the first device is normal, the distance from the sensor of the first device to the magnet of the second device is less than the magnetic field range of the magnet, and the closer the magnet is to the sensor, the greater the magnetic field strength detected by the sensor. The magnetic field range of the magnet corresponds to the first preset threshold. When the magnetic field strength of the magnet in the second device detected by the sensor is greater than the first preset threshold, it indicates that the sensor of the first device is located within the magnetic field range of the magnet in the second device, the sensor of the first device can normally sense the magnetic field strength of the magnet in the second device, and the mechanical connection between the second device and the first device is normal.

[0159] Step S133: If the magnetic field strength of the magnet in the second device is less than or equal to a first preset threshold, a mechanical connection abnormality is determined in the second device. When the mechanical connection between the second device and the first device is abnormal, the distance from the sensor of the first device to the magnet of the second device exceeds the magnetic field range of the magnet, and the farther the magnet is from the sensor, the smaller the magnetic field strength detected by the sensor. The magnetic field range of the magnet corresponds to the first preset threshold. When the magnetic field strength of the magnet in the second device detected by the sensor is less than or equal to the first preset threshold, it indicates that the sensor of the first device is located at or outside the magnetic field range of the magnet of the second device, and the sensor of the first device cannot normally sense the magnetic field strength of the magnet of the second device, indicating a mechanical connection abnormality between the second device and the first device.

[0160] The sensor in the first device detects the magnetic field strength of the magnet in the second device to determine if the mechanical connection between the two devices is normal, thus determining whether the second device is properly mounted on the first device. The sensor is located near the magnet in the second device. The first and second devices only need to sense the magnetic field strength of the magnet to determine the mounting status of the second device, improving the working efficiency of both devices. The first device uses the sensor to detect the magnetic field strength of the magnet to determine whether the second device is correctly mounted on it, improving the security of the connection between the two devices. For example, the first device can be a 3D printing head, and the second device can be a laser head or a connector; in this case, the laser head or connector is mounted on the 3D printing head. Alternatively, the first device can be a laser head or a connector, and the second device can be a 3D printing head; in this case, the 3D printing head is mounted on the laser head or connector.

[0161] Please see Figure 22 The method for identifying mounting information provided in this application is also used to detect whether the electrical connection between the first device and the second device is normal. The steps for detecting whether the electrical connection between the first device and the second device is normal include:

[0162] Step S141: Obtain the communication frequency between the first device and the second device. In this application, the first device can obtain the communication frequency of the second device via a cable. For example, the first device sends a signal to the second device via the cable, and after receiving the signal, the second device returns a processing signal and reacts to the signal sent by the first device. The first device calculates the time of the second device's return of the processing signal and its reaction to determine whether the electrical connection between the first and second devices is normal. Optionally, the second device can also send a signal to the first device, and then the second device receives a response from the first device. For example, the second device sends a signal to the first device via a cable, and after receiving the signal, the first device returns a processing signal and reacts to the signal sent by the second device. The second device calculates the time of the first device's return of the processing signal and its reaction to determine whether the electrical connection between the first and second devices is normal.

[0163] Step S142: If the communication frequency between the first device and the second device is greater than the target value, then the electrical connection of the second device is considered normal. The communication frequency of the second device corresponds to a target value. When the speed at which the second device returns a processing signal to the first device and responds to the signal sent by the first device is greater than the target value, it indicates that the second device can correctly and timely respond to the signal sent by the first device, and the first device determines that the electrical connection of the second device is normal. Optionally, when the speed at which the first device returns a processing signal to the second device and responds to the signal sent by the second device is greater than the target value, it indicates that the first device can correctly and timely respond to the signal sent by the second device, and the second device determines that the electrical connection of the first device is normal.

[0164] Step S143: If the communication frequency between the first device and the second device is less than or equal to a target value, the electrical connection of the second device is determined to be abnormal. The communication frequency of the second device corresponds to a target value. When the speed at which the second device returns a processing signal to the first device and responds to a signal sent by the first device is less than or equal to the target value, it indicates that the second device cannot correctly and timely respond to the signal sent by the first device, and the first device determines that the electrical connection of the second device is abnormal. Optionally, when the speed at which the first device returns a processing signal to the second device and responds to a signal sent by the second device is less than or equal to the target value, it indicates that the first device can correctly and timely respond to the signal sent by the second device, and the second device determines that the electrical connection of the first device is normal.

[0165] The first device detects the communication frequency of the second device to determine if communication between them is normal, and then determines if their electrical connection is normal. When the electrical connection is normal, the first device proceeds to the next step, controlling the second device to process the product. If the electrical connection is abnormal, the first device issues a warning, reminding the operator to check the cable connection between them. Alternatively, the second device detects the communication frequency of the first device to determine if communication between them is normal, and then determines if their electrical connection is normal. When the electrical connection is normal, the second device proceeds to the next step, controlling the first device to process the product. If the electrical connection is abnormal, the second device issues a warning, reminding the operator to check the cable connection between them.

[0166] If the mechanical and electrical connections of the second device are normal, the system retrieves information on whether the mechanical and electrical connections of the second device were normal in the previous detection. A normal mechanical connection is defined as the magnetic field strength of the magnet of the second device being greater than a first preset threshold; a normal electrical connection is defined as the communication frequency of the second device being greater than a target value. The system also retrieves information on whether the electrical connection status of the second device is abnormal, both currently and before a second preset time. If the mechanical and electrical connections of the second device were abnormal in the previous detection, the system controls the second device to enter initialization mode.

[0167] After the second device is connected to the first device, the first device detects the magnetic field strength of the second device's magnet using a sensor and acquires the communication frequency of the second device via a cable. When the magnetic field strength of the second device's magnet is greater than a first preset threshold and the communication frequency of the second device is greater than a target value, it is determined that the mechanical and electrical connections between the second and first devices are normal, indicating that the second device is currently connected normally to the first device. If the second device is confirmed to be normally connected to the first device, the first device acquires the magnetic field strength of the magnet previously detected by the second device and the communication frequency previously detected by the second device. When the magnetic field strength of the magnet previously detected by the second device is less than or equal to the first preset threshold and the communication frequency previously detected by the second device is less than or equal to the target value, it is determined that the previous connection between the second and first devices was abnormal. Currently, the mechanical and electrical connections between the first and second devices are normal. The previous situation where the mechanical and electrical connections between the first and second devices were abnormal indicates that the second device was first installed on the first device, and the connection between the second and first devices is normal. The second device can process the product, or the second device can perform secondary processing on the product / part of the product processed by the first device. At this time, the control of the second device enters the initialization, so that all data in the system are restored to the initial value, and the second device is aligned with its position on the equipment coordinates of the processing equipment.

[0168] In the event of an abnormal mechanical or electrical connection of the second device, the system retrieves information on whether the mechanical and electrical connections of the second device were normal in the previous detection. A normal mechanical connection is defined as the magnetic field strength of the magnet of the second device exceeding a first preset threshold; a normal electrical connection is defined as the communication frequency of the second device exceeding a target value. If the mechanical and electrical connections of the second device were normal in the previous detection, the system determines that the second device has been removed from the first device.

[0169] After the second device is connected to the first device, the first device detects the magnetic field strength of the second device's magnet through a sensor and acquires the communication frequency of the second device through a cable. When the magnetic field strength of the second device's magnet is less than or equal to a first preset threshold and the communication frequency of the second device is less than or equal to a target value, it is determined that the mechanical and electrical connections between the second and first devices are abnormal, indicating that the second device is not currently properly connected to the first device. If the second device is determined to be not properly connected to the first device, the first device acquires the magnetic field strength of the magnet previously detected by the second device and the communication frequency previously detected by the second device. When the magnetic field strength of the magnet previously detected by the second device is greater than the first preset threshold and the communication frequency previously detected by the second device is greater than the target value, it is determined that the previous connection between the second and first devices was normal. Since the current mechanical and electrical connections between the first and second devices are abnormal, while the previous mechanical and electrical connections were normal, it indicates that the mounting state of the second device and the first device is a process of installation to removal, and it is determined that the second device has been removed from the first device.

[0170] During each processing iteration, the magnetic field strength of the second device's magnet and the communication frequency of the second device, detected by the first device, are stored in the system's database. The first device retrieves data from the database to confirm the previous mechanical and electrical connection status of the second device. If the current mechanical and electrical connections of the second device are normal, but the previous mechanical and electrical connections were abnormal, it is determined that the second device is now properly connected to the first device. At this point, the second device is initialized, preparing for a new secondary processing iteration. If the current mechanical and electrical connections of the second device are abnormal, and the previous mechanical and electrical connections were also abnormal, it is determined that the second device is detached from the first device. By analyzing the current and previous states of the magnetic field strength and communication frequency of the second device's magnet, the first device determines the current mounting status of the second device with the first device, improving the matching degree between the two devices and also increasing the working efficiency of both devices.

[0171] After the first and second devices are properly connected, either the first or second device stores data about the second device's operation, including its initialization sequence. The first device analyzes the second device's initialization sequence to determine whether initialization of the second device is necessary. Please refer to [link to relevant documentation]. Figure 23 The steps for the first device to determine whether the second device needs initialization include:

[0172] Step S151: Obtain the initialization sequence of the second device. The initialization sequence of the second device can be stored in the second device itself or in the first device. The initialization sequence of the second device includes setting the working position of the second device, the working angle of the second device, and the working state of the components in the second device. For example, when the second device is a laser head, the initialization sequence includes the position of the laser head from the processing platform; when the second device is a cutting assembly, the initialization sequence includes the angle of the cutting head; when the second device is a pen, the initialization sequence includes the ink flow rate of the pen.

[0173] Step S152: Determine whether the memory stores an initialization flag corresponding to the initialization sequence. The memory can be located in the first device or the second device. In this application, the memory is located in the first device. The first device obtains the initialization sequence of the second device via a cable and determines whether there is a data group in the memory with the same value as the initialization sequence of the second device. If there is a data group in the memory with the same value as the initialization sequence of the second device, it is considered that the memory stores an initialization flag corresponding to the initialization sequence. If there is no data group in the memory with the same value as the initialization sequence of the second device, it is considered that the memory does not store an initialization flag corresponding to the initialization sequence.

[0174] Step S153: If yes, then the second device does not need to be initialized. If the data group in the memory has an initialization flag corresponding to the initialization sequence of the second device, it is determined that the second device has been initialized in this working cycle, and the first device does not need to initialize the second device, thus avoiding clearing the working data record of the second device.

[0175] Step S154: If not, the second device is initialized. If the data group in the memory does not have an initialization flag corresponding to the initialization sequence of the second device, it is determined that the second device has not been initialized in this working cycle. The first device initializes the second device, transforming the working data of the second device into initial values, so that the second device is ready to perform new secondary processing.

[0176] After the first device is connected to the second device, the initialization sequence of the second device is obtained, and the memory is checked for an initialization flag corresponding to the initialization sequence. This determines whether the second device should be initialized, avoiding the problem of re-initialization when the second device has already been initialized. It also prevents the second device from being repeatedly initialized and damaging the working data records, thus improving work efficiency.

[0177] The mounting status and type information of the second device are presented via voice announcement or visual display. The type of the second device detected by the first device through its sensors, the mounting status determined by the first device through its sensors detecting the magnetic field strength of the second device's magnet, and the connection status determined by the first device through its cable-based communication frequency are all presented via voice announcement or visual display. The device used for voice announcement can be a speaker, which can be installed on either the first or second device. The device used for visual display can be a display screen or a window display of the control module that controls the movement of the first and second devices. The presentation of the mounting status and type information of the second device via voice announcement or visual display can include various formats; for example, the voice announcement may state that the first device is equipped with a laser head, that the mechanical connection between the laser head and the first device is normal, that the electrical connection between the laser head and the first device is normal, and that the laser head has been initialized. Through voice broadcast or visual presentation, it is easy to know the type of the second device attached to the first device and whether the second device is correctly attached to the first device. There is no need to retrieve data from the storage device for inspection. The operation is simple and convenient, and the voice broadcast or visual presentation is timely, which shortens the operator's operation time and improves the operator's work efficiency.

[0178] Please see Figure 24 Another method for use in processing equipment provided in this application includes the following steps:

[0179] Step S201: Obtain the identity information of the second device. The identity information includes a first identifier set on the laser head, a second identifier set on the connector, or a third identifier set on the print head. When the second device is attached to the first device, it is also connected to the first device via a cable, and the first and second devices communicate with each other via the cable. When the first device is a print head, the second device includes a laser head or a connector. The laser head and connector are respectively marked with an identifier; the identifier for the laser head is the first identifier, and the identifier for the connector is the second identifier. The identity information of the second device includes either the first identifier of the laser head or the second identifier of the connector. The print head obtains the identity information of the second device via the cable, identifies the identifier within the identity information, and determines whether the second device is connected to a connector, a laser head, or a print head. The first device can also transmit motion commands to the second device via the cable to control the movement of the second device. When the second device is attached to the first device, the first device can also supply power to the second device via the cable. When the first device is a laser head or connector, the second device is a print head, and the identifier corresponding to the print head is a third identifier. The identification information of the second device includes the third identifier of the print head. The laser head or connector obtains the identification information of the second device through a cable, identifies the identifier within the identification information, and determines that the second device is connected to the print head. In this application, it can be a print head sliding connection guide or a laser head / connector sliding connection guide.

[0180] Step S202: Based on the identity information, obtain at least one of the mounting status information and type information of the second device. The first device obtains the identity information of the second device through a cable and identifies the first identifier, second identifier, and third identifier in the second device. When the first device identifies the first identifier, it determines that the second device mounted on the first device is a laser head; when the first device identifies the second identifier, it determines that the second device mounted on the first device is a connector; when the first device identifies the third identifier, it determines that the second device mounted on the first device is a print head.

[0181] The first device uses the identification information of the second device obtained through the cable to determine whether the first device is equipped with a laser head, a connector, or a print head. This allows it to determine the type of processing that can be performed by both devices. For example, if the first device is a 3D print head and the second device is a laser head or a connector, the 3D print head obtains and identifies the second device's identification information through the cable. When the 3D print head determines that it is equipped with a laser head, it can laser-engrave the 3D-printed product / partial product after printing or during the printing process. Alternatively, the laser head can place processing consumables such as acrylic sheets, wood, metal, glass, stainless steel, or rock on a processing platform, allowing it to process products other than 3D-printed products. When the 3D print head determines that it is equipped with a connector, and the connector is connected to a cutting assembly, the cutting assembly is used to cut the 3D-printed product / partial product after printing or during the printing process, removing any excess parts. Alternatively, the cutting assembly can perform secondary processing on the 3D-printed product, cutting it into the desired shape. When the 3D printing head determines that the connector is attached, and the connector connects to the pen holder, the pen can be used for drawing and design on the 3D-printed product / part of the product. The pen has an adjustable tip and ink to achieve different drawing effects and precision. The pen is detachably connected to the pen holder, allowing for multi-colored drawing by changing different colored pens, and different pen effects by changing different types of pens.

[0182] The first device acquires the identity information of the second device through a cable and determines the type of the second device attached to the first device based on the identity information, making the movements of the first and second devices more matched, reducing the number of times the laser head and connector are repeatedly installed and removed, and improving production efficiency and work efficiency.

[0183] Optionally, in some feasible implementations, the laser head includes laser heads with various powers, each with different identification information. For example, the laser head may have powers of 10W, 40W, etc., with different powers corresponding to different identification information. Step S202 reveals that the second device mounted on the first device is a laser head, but its power is unknown. In application scenarios with laser heads of various processing powers, implementing this application allows the identification information of the second device to be obtained via cable. By analyzing the obtained identification information, the first device determines the power of the laser head mounted on it based on the identification information, further improving processing accuracy and increasing automation. When the first device is a 3D printing head, the 3D printing head determines the extent to which the laser head can perform secondary processing on the 3D printed product / part of the product based on the different powers of the laser head, resulting in a higher degree of matching between the 3D printing head and the laser head, and improving the working efficiency of both.

[0184] Optionally, in some feasible implementations, when the first device is a 3D printing head and the second device is a connector, the connector is connected to a pen and a cutting assembly. The pen is connected to the connector via a pen holder, wherein the pen holder has a magnet, and the cutting assembly has a magnet, the magnetic polarities of the magnet on the pen holder and the magnet on the cutting assembly being different. The first device determines whether the second device attached to the first device is connected to a pen or a cutting assembly by detecting the magnetic polarity of the magnet on the pen holder or the cutting assembly.

[0185] The brush is connected to the connector via a brush holder, which has a magnet and the cutter assembly has a magnet. The magnets on the brush holder and the cutter assembly have different magnetic polarities.

[0186] Please see Figure 25 When determining that the second device connected to the first device is a connector, the first device determines whether the second device attached to the first device is connected to a pen or a cutter assembly by detecting the magnetic polarity of the magnet on the pen holder or cutter assembly. The method includes the following steps:

[0187] Step S211: If the second device is a connector, detect the magnetic polarity connected to the connector.

[0188] Step S212: Based on the magnetic polarity of the connector, it is determined whether the connector is connected to a pen or cutter assembly.

[0189] When the second device is a connector, a cutter assembly or a pen is connected to the connector via a pen holder. Both the pen holder and the cutter assembly have magnets. The magnetic polarity of the magnet on the pen holder facing the sensor of the first device is opposite to the magnetic polarity of the magnet on the cutter assembly facing the sensor of the first device. The first device determines whether the connector is connected to the pen holder or the cutter assembly by detecting the magnetic polarity of the magnets in the connector. For example, the magnet on the pen holder has a north pole (N) facing the sensor, and the magnet on the cutter assembly has a south pole (S). When the sensor detects the north pole, the connector is connected to the pen; when the sensor detects the south pole, the connector is connected to the cutter assembly. The first device detects whether the connector is connected to the pen or the cutter assembly by the magnetic polarity of the magnets in the connector. When the first device is equipped with a pen, the pen can be used for drawing and design on the 3D printed product / part of the product. The pen has an adjustable tip and ink to achieve different drawing effects and precision. The paintbrush is detachably connected to a pen holder, allowing for colorful painting by changing different colors and achieving different effects by switching brush types. When the first device is equipped with a cutter assembly, the cutter assembly is used to cut the 3D-printed product / part of the product after printing or during the printing process, removing excess parts. Alternatively, the cutter assembly can perform secondary processing on the 3D-printed product, cutting it into the desired shape. The cutter assembly can be made of high-hardness materials, such as tool steel and hard alloys. The cutter head is detachable and can be of various types, such as disc cutters and pointed cutters, providing multiple cutting methods. Alternatively, materials such as wood, paper, plastic, leather, metal sheets (e.g., foil), and fabric can be placed on the processing platform, allowing the cutter assembly to process products other than 3D-printed ones. In this application, the connector can be compatible with the connection of the cutter assembly and the pen holder. By sharing the same set of motion devices, such as guide rods / processing platforms, with the 3D printing head, a variety of different processing methods can be realized. The connector can also connect to cutter assemblies with different cutter types and to pens of different colors / types, which can be combined to create a variety of processing methods, greatly enriching the processing forms and processing efficiency of the processing equipment.

[0190] Optionally, in some feasible implementations, the first device includes a 3D printing head equipped with a sensor, and the second device includes a laser head or connector equipped with a magnet, wherein the magnet on the laser head and the magnetic poles on the connector have different polarities. When the laser head or connector is attached to the 3D printing head, the sensor on the 3D printing head identifies the presence or absence of the magnet on the second device to determine whether the second device is attached to the 3D printing head. When the sensor on the 3D printing head detects that a connector or laser head is attached to the second device, the sensor on the 3D printing head identifies the polarity of the magnet on the second device facing the sensor to determine whether a laser head or a connector is attached to the 3D printing head. The sensor can determine the attachment status and type of the second device simply by identifying the magnetic pole polarity of the magnet, simplifying the mechanical structure of the processing equipment and improving the production efficiency and working efficiency of the processing equipment.

[0191] Please see Figure 26 The method for identifying mount status or type provided in this application includes the following steps:

[0192] Step S221: Obtain the magnetic polarity of the magnet in the second device. A sensor on the 3D printing head identifies the magnetic polarity of the magnet in the second device attached to the 3D printing head. The sensor can be a Hall sensor or an eddy current coil. In this application, the magnet on the laser head has a different magnetic polarity than the magnet on the connector head. The sensor determines whether the connector head or the laser head is attached to the 3D printing head by identifying the magnetic polarity of the magnet in the second device.

[0193] Step S222: Based on the magnetic polarity of the magnet, at least one of the mounting state and type of the laser head or the connector is obtained. A sensor on the 3D printing head determines at least one of the mounting state and type of the second device mounted on the 3D printing head by sensing the polarity of the magnet on the second device facing the sensor. For example, if the magnet on the connector has a north pole (N) facing the sensor, and the magnet on the laser head has a south pole (S), when the sensor detects the north pole, it is determined that the device mounted on the 3D printing head is a connector; when the sensor detects the south pole, it is determined that the device mounted on the 3D printing head is a laser head. The sensor determines whether the second device is connected to a laser head or a connector by identifying the magnetic polarity of the magnet, and determines the actions that the second device and the first device can perform. For example, when the sensor determines that the 3D printing head is connected to a laser head, it can directly perform laser engraving / cutting on the product to be processed, or perform laser engraving on the product processed by the 3D printing head after processing. When the sensor determines that the 3D printing head is connected to a connector, it can directly cut / draw patterns on the product to be processed, or cut or draw patterns on the product processed by the 3D printing head after processing. This improves the matching degree between the 3D printing head and the connector / laser head, and avoids damage to the product caused by mismatch between the 3D printing head and the connector / laser head.

[0194] Optionally, the sensors on the 3D printing head can determine whether the second device is mounted by sensing the magnetic polarity of the magnet in the second device. For example, if the sensor detects a magnetic field, it can determine that the second device is mounted. Further, in some optional embodiments, if the sensors on the 3D printing head detect that the magnetic pole in the second device is N (northeast), it can determine that the connector is mounted; if the sensors on the 3D printing head detect that the magnetic pole in the second device is S (south), it can determine that the laser head is mounted.

[0195] Optionally, in some feasible embodiments, one of the first device and the second device is provided with a sensor, and the other is provided with a magnet. For example, the first device is provided with a sensor, and the second device is provided with a magnet, or the first device is provided with a magnet, and the second device is provided with a sensor. For some feasible embodiments, please refer to... Figure 27 Based on the magnetic polarity of the magnet in the second device, at least one of the mounting state and type of the second device is obtained, the steps of which include:

[0196] Step S231: Detect the magnetic field strength of the magnet in the second device or the first device. In this application, the magnetic field strength of the magnet in the second device is detected by a sensor in the first device, or the magnetic field strength of the magnet in the first device is detected by a sensor in the second device. For example, the sensor in the first device is a Hall effect sensor. The Hall effect sensor is placed in the magnetic field generated by the magnet, energized, and the voltage difference across the Hall sensor is measured. The magnetic field strength is calculated based on the Hall coefficient and the current.

[0197] Step S232: If the magnetic field strength of the magnet of the second device or the first device is greater than a first preset threshold, it is determined that the mechanical connection between the second device and the first device is normal. For example, when the mechanical connection between the second device and the first device is normal, the distance from the sensor of the first device to the magnet of the second device is less than the magnetic field range of the magnet, and the closer the magnet is to the sensor, the greater the magnetic field strength detected by the sensor. The magnetic field range of the magnet corresponds to the first preset threshold. When the magnetic field strength of the magnet of the second device detected by the sensor is greater than the first preset threshold, it indicates that the sensor of the first device is located within the magnetic field range of the magnet of the second device, the sensor of the first device can normally sense the magnetic field strength of the magnet of the second device, and the mechanical connection between the second device and the first device is normal.

[0198] Step S233: If the magnetic field strength of the magnet of the second device or the first device is less than or equal to a first preset threshold, it is determined that the mechanical connection between the second device and the first device is abnormal. For example, when the mechanical connection between the second device and the first device is abnormal, the distance from the sensor of the first device to the magnet of the second device exceeds the magnetic field range of the magnet, and the farther the magnet is from the sensor, the smaller the magnetic field strength detected by the sensor. The magnetic field range of the magnet corresponds to the first preset threshold. When the magnetic field strength of the magnet of the second device detected by the sensor is less than or equal to the first preset threshold, it indicates that the sensor of the first device is located at or outside the magnetic field range of the magnet of the second device, and the sensor of the first device cannot normally sense the magnetic field strength of the magnet of the second device, indicating that the mechanical connection between the second device and the first device is abnormal.

[0199] The sensor in the first device detects the magnetic field strength of the magnet in the second device to determine if the mechanical connection between the two devices is normal, thus determining whether the second device is properly mounted on the first device. The sensor is located near the magnet in the second device. The first device uses the sensor to detect the magnetic field strength of the magnet to determine if the second device is correctly mounted, improving the security of the connection between the two devices. For example, the first device can be a 3D printing head, and the second device can be a laser head or a connector; in this case, the laser head or connector is mounted on the 3D printing head. Alternatively, the first device can be a laser head or a connector, and the second device can be a 3D printing head; in this case, the 3D printing head is mounted on the laser head or a connector.

[0200] In some feasible embodiments, the processing equipment may further include a third device, which is detachably connected to the first device as a second device. Unlike the second device, the third device is not connected to the first device via a cable. Both the third and second devices have magnets, but the magnets in the second and third devices are different. Therefore, the polarity of the magnets connected to the first device can be used to determine whether the first device is connected to the second or third device. In this application, the third device can be a passive processing device, which is compatible with the installation of passive processing devices without cable connections onto the first device, enriching the processing methods and simplifying the installation process.

[0201] Please see Figure 28 The method for processing equipment provided in this application is also used to detect whether the electrical connection between the first device and the second device is normal. The steps for detecting whether the electrical connection between the first device and the second device is normal include:

[0202] Step S241: Obtain the communication frequency between the first device and the second device. In this application, the first device obtains the communication frequency of the second device via a cable, sends a signal to the second device via the cable, and after receiving the signal, the second device returns a processing signal and responds to the signal sent by the first device. The first device calculates the time between the second device's return of the processing signal and its response to determine whether the electrical connection between the first and second devices is normal. Optionally, the second device can also send a signal to the first device, and then the second device receives a response from the first device. For example, the second device sends a signal to the first device via a cable, the first device receives the signal, returns a processing signal, and responds to the signal sent by the second device. The second device calculates the time between the first device's return of the processing signal and its response to determine whether the electrical connection between the first and second devices is normal.

[0203] Step S242: If the communication frequency between the first device and the second device is greater than the target value, then the electrical connection between the first device and the second device is considered normal. The communication frequency of the second device corresponds to a target value. When the speed at which the second device returns a processing signal to the first device and responds to the signal sent by the first device is greater than the target value, it indicates that the second device can correctly and timely respond to the signal sent by the first device, and the first device determines that the electrical connection between the second device and the second device is normal. Optionally, when the speed at which the first device returns a processing signal to the second device and responds to the signal sent by the second device is greater than the target value, it indicates that the first device can correctly and timely respond to the signal sent by the second device, and the second device determines that the electrical connection between the first device and the second device is normal.

[0204] Step S243: If the communication frequency between the first device and the second device is less than or equal to a target value, an electrical connection abnormality between the first device and the second device is determined. The communication frequency of the second device corresponds to a target value. When the speed at which the second device returns a processing signal to the first device and responds to a signal sent by the first device is less than or equal to the target value, it indicates that the second device cannot correctly and timely respond to the signal sent by the first device, and the first device determines that the electrical connection between the second device is abnormal. Optionally, if the speed at which the first device returns a processing signal to the second device and responds to a signal sent by the second device is less than or equal to the target value, it indicates that the first device can correctly and timely respond to the signal sent by the second device, and the second device determines that the electrical connection between the first device and the second device is normal.

[0205] The first device detects the communication frequency between itself and the second device to determine if their communication is normal, and then checks the electrical connection between them. If the connection is normal, the first device proceeds to the next step, controlling the second device to perform secondary processing on the product. If the connection is abnormal, the first device issues a warning, reminding the operator to check the cable connection between them. Alternatively, the second device detects the communication frequency of the first device to determine if their communication is normal, and then checks the electrical connection. If the connection is normal, the second device proceeds to the next step, controlling the first device to process the product. If the connection is abnormal, the second device issues a warning, reminding the operator to check the cable connection between them.

[0206] If the mechanical connection between the first device and the second device is normal, and the electrical connection between the first device and the second device is normal, the system obtains whether the mechanical connection and electrical connection between the first device and the second device were normal in the previous test. The mechanical connection is normal when the magnetic field strength of the magnet of the first device or the second device is greater than a first preset threshold. The electrical connection is normal when the communication frequency between the first device and the second device is greater than a target value. If the mechanical connection and electrical connection between the first device and the second device were abnormal in the previous test, the system controls the second device attached to the first device to enter initialization or controls the first device attached to the second device to enter initialization.

[0207] After the second device is connected to the first device, the first device detects the magnetic field strength of the second device's magnet using a sensor. The first device also acquires the communication frequency of the second device via a cable. When the magnetic field strength of the second device's magnet is greater than a first preset threshold and the communication frequency between the first and second devices is greater than a target value, it is determined that the mechanical and electrical connections between the second and first devices are normal, indicating that the second device is currently connected normally to the first device. If the second device is confirmed to be electrically connected normally to the first device, the first device acquires the magnetic field strength of the magnet previously detected by the second device and the previously detected communication frequency between the first and second devices. When the magnetic field strength of the magnet previously detected by the second device is less than or equal to the first preset threshold, and the previously detected communication frequency between the first and second devices is less than or equal to the target value, it is determined that the previous connection between the second and first devices was abnormal. Currently, the mechanical and electrical connections between the first and second devices are normal, whereas the previous connection was abnormal. This indicates that the second device is being installed on the first device for the first time, and the connection is normal. The second device can process the product, or it can perform secondary processing on the product / part of the product processed by the first device. In this case, the second device is controlled to enter initialization, restoring all data in the system to their initial values ​​and aligning the second device with its position on the equipment coordinates of the processing equipment. Optionally, the situation where the mechanical and electrical connections between the first and second devices are normal, whereas the previous connection was abnormal, indicates that the first device is being installed on the second device for the first time, and the connection is normal. The first device can process the product, or it can perform secondary processing on the product / part of the product processed by the second device. In this case, the first device is controlled to enter initialization, restoring all data in the system to their initial values ​​and aligning the first device with its position on the equipment coordinates of the processing equipment.

[0208] In the event of an abnormal mechanical connection or an abnormal electrical connection between the first and second devices, the system retrieves whether the mechanical and electrical connections between the first and second devices were normal in the previous test. A normal mechanical connection is defined as the magnetic field strength of the magnet of the second device being greater than a first preset threshold; a normal electrical connection is defined as the communication frequency between the first and second devices being greater than a target value. If the mechanical and electrical connections of the second device were normal in the previous test, it is determined that the second device has been removed from the first device.

[0209] After the second device is connected to the first device, the first device detects the magnetic field strength of the second device's magnet through a sensor. The first device also acquires the communication frequency between the first and second devices via a cable. When the magnetic field strength of the second device's magnet is less than or equal to a first preset threshold and the communication frequency between the first and second devices is less than or equal to a target value, it is determined that both the mechanical and electrical connections between the second and first devices are abnormal, indicating that the second device is not currently properly connected to the first device. If the second device is determined to be not properly connected to the first device, the first device acquires the magnetic field strength of the magnet previously detected by the second device and the previously detected communication frequency between the first and second devices. When the magnetic field strength of the magnet previously detected by the second device is greater than the first preset threshold and the previously detected communication frequency between the first and second devices is greater than the target value, it is determined that the previous connection between the second and first devices was normal. Since both the mechanical and electrical connections between the first and second devices are currently abnormal, but the previous connections were normal, it indicates that the mounting state of the second and first devices is a process of installation to removal, thus determining whether the second device is removed from the first device or the first device is removed from the second device.

[0210] During each processing iteration, the magnetic field strength values ​​of the magnets of either the first or second device, detected by the first device, and the communication frequency between them are stored in the system's database. For example, the first device retrieves data from the database to confirm the previous mechanical and electrical connection status of the second device. If the current mechanical and electrical connections of the second device are normal, but the previous connections were abnormal, it is determined that the second device is now properly connected to the first device. At this point, the second device is initialized to prepare for the next processing iteration. If the current mechanical and electrical connections of the second device are abnormal, and the previous connections were also abnormal, it is determined that the second device is detached from the first device. By analyzing the current and previous magnetic field strength and communication frequency status of the second device's magnets, the first device determines the current mounting status of the second device with the first device, improving the matching degree between the two devices and also increasing their working efficiency.

[0211] After the first and second devices are properly connected, either the first or second device stores data about the second device's operation, including its initialization sequence. The first device analyzes the second device's initialization sequence to determine whether initialization of the second device is necessary. Please refer to [link to relevant documentation]. Figure 29 The steps for the first device to determine whether the second device needs initialization include:

[0212] Step S251: Obtain the initialization sequence of the second device. The initialization sequence of the second device can be stored in the second device itself or in the first device. The initialization sequence of the second device includes setting the working position of the second device, the working angle of the second device, and the working state of the components in the second device. For example, when the second device is a laser head, the initialization sequence includes the position of the laser head from the processing platform; when the second device is a cutting assembly, the initialization sequence includes the angle of the cutting head; when the second device is a pen, the initialization sequence includes the ink flow rate of the pen.

[0213] Step S252: Determine whether the memory stores an initialization flag corresponding to the initialization sequence. The memory can be located in the first device or the second device. In this application, the memory is located in the first device. The first device obtains the initialization sequence of the second device via a cable and determines whether there is a data group in the memory with the same value as the initialization sequence of the second device. If there is a data group in the memory with the same value as the initialization sequence of the second device, it is considered that the memory stores an initialization flag corresponding to the initialization sequence. If there is no data group in the memory with the same value as the initialization sequence of the second device, it is considered that the memory does not store an initialization flag corresponding to the initialization sequence.

[0214] Step S253: If yes, then the second device does not need to be initialized. If the data group in the memory has an initialization flag corresponding to the initialization sequence of the second device, it is determined that the second device has been initialized in this working cycle, and the first device does not need to initialize the second device, thus avoiding clearing the working data record of the second device.

[0215] Step S254: If not, the second device is initialized. If the data group in the memory does not have an initialization flag corresponding to the initialization sequence of the second device, it is determined that the second device has not been initialized in this working cycle. The first device initializes the second device, converting the working data of the second device into initial values, so that the second device is ready to perform new secondary processing.

[0216] After the first device is connected to the second device, the initialization sequence of the second device is obtained, and the memory is checked for an initialization flag corresponding to the initialization sequence. This determines whether the second device should be initialized, avoiding the problem of re-initialization when the second device has already been initialized. It also avoids the problem of the second device being repeatedly initialized and damaging the working data records, thus improving work efficiency.

[0217] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0218] Furthermore, the use of terms such as "first," "second," etc., in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0219] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0220] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.

[0221] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
