Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a processing module and processing equipment using the processing module. Background Technology

[0002] In processing equipment such as laser processing equipment and 3D printing equipment, it is usually necessary to set up a distance detection mechanism to detect the distance between the processing head and the processing surface, or the thickness of the workpiece.

[0003] However, the distance detection mechanism in the processing equipment of the related technology is easily affected by its production errors and assembly tolerances, resulting in low detection accuracy and affecting the accuracy of distance detection between the processing head and the processing surface. Utility Model Content

[0004] The main objective of this application is to provide a processing module and processing equipment, which aims to improve the accuracy of detecting the distance between the processing head and the processing surface or the thickness of the workpiece.

[0008] The magnet module is movable relative to the magnetic induction element along a first direction. The magnetic induction element is used to detect the magnetic field signal provided by the magnet module, so as to determine whether the distance detection mechanism is triggered based on the detected change signal of the magnetic field.

[0009] In some embodiments, the processing head has a receiving cavity, and both the magnetic induction element and the magnet module are at least partially disposed within the receiving cavity.

[0010] In some embodiments, the processing head includes a first structure and a second structure, wherein the second structure is movably connected to the first structure along a first direction and together with the first structure forms the receiving cavity;

[0011] Both the magnetic induction element and the magnet module are completely disposed within the receiving cavity and are respectively fixed to the first structure and the second structure.

[0012] In some embodiments, the first structure has a first space, the second structure has a second space, and the first space and the second space are sequentially arranged and connected in the first direction to form the receiving cavity;

[0013] At least a portion of one of the magnetic induction element and the magnet module is fixedly inserted into the second space, while the other is disposed in the first space.

[0015] And / or, the second space is a threaded hole, and the magnet module is threadedly connected to the second space.

[0016] In some embodiments, the magnet module includes a carrier and a magnetic body, with one end of the carrier fixedly inserted into the second space;

[0017] The magnetic element is mounted on the end of the carrier facing the magnetic induction element and is used to provide a magnetic field signal.

[0018] In some embodiments, the support member includes a rod portion and a base portion, one end of the rod portion is fixedly inserted into the second space, and the other end extends into the first space, the base portion is connected to the rod portion located in the first space, and the magnetic component is installed on the base portion;

[0019] And / or, the carrier is provided with a fixing groove, and the magnet is installed in the fixing groove.

[0020] In some embodiments, the first structure includes a laser head body, a protective lens module, and a circuit board, and the second structure is an air nozzle; the circuit board is disposed between the laser head body and the protective lens module, the protective lens module and the circuit board enclose the first space, and the magnetic induction element is mounted on the circuit board;

[0021] Alternatively, the first structure includes a printhead body, a heating module, and a circuit board, and the second structure is a nozzle; the circuit board is disposed between the printhead body and the heating module, the heating module and the circuit board enclose the first space, and the magnetic induction element is mounted on the circuit board.

[0022] In some embodiments, the first structure further includes a first sealing gasket, which is disposed between the laser head body and the circuit board, or between the print head body and the circuit board;

[0023] And / or, the first structure further includes a second sealing gasket, which is disposed between the protective mirror module and the circuit board, or between the heating module and the circuit board.

[0024] In some embodiments, the second structure and the first structure are spaced apart and magnetically connected in the first direction, and the processing module further includes a first elastic element disposed between the first structure and the second structure.

[0025] In some embodiments, the second structure is provided with a channel that extends through opposite sides of the second structure in the first direction; the first elastic member is an annular structure and is disposed around the channel opening near one end of the first structure.

[0026] The first elastic member includes a body portion and a protrusion portion. The body portion is disposed around the channel, and the protrusion portion protrudes from the side of the body portion facing the first structure and contacts the first structure.

[0027] In some embodiments, the second structure has an abutting protrusion on the side opposite to the first structure. The abutting protrusion abuts against the processing surface so that the abutting protrusion is subjected to force and drives the magnet module to move relative to the magnetic induction element in a first direction.

[0028] In some embodiments, one of the magnetic induction element and the magnet module is completely disposed within the receiving cavity, and the other is movable within the receiving cavity along a first direction and extends partially through the processing head to the outside of the receiving cavity to abut against the processing surface, so that the other moves relative to the first under the force of the processing surface.

[0030] The distance detection mechanism further includes a second elastic element, which is disposed within the accommodating cavity and acts on the magnet module;

[0031] The second elastic element is used to drive the magnet module to move and reset when the force on the processed surface is removed.

[0032] This application also proposes a processing apparatus, comprising:

[0033] The housing has a processing cavity;

[0034] Track device, the track device being disposed within the housing; and

[0035] The processing module described above is located on the track device and can be driven to move by the track device.

[0036] The processing module of this application includes a distance detection mechanism comprising a magnetic induction element and a magnet module. The magnetic induction element features high sensitivity and high resolution, enabling it to detect even weak changes in magnetic field signals. Simultaneously, the magnet module is configured to move relative to the magnetic induction element along a first direction. When the processing head moves relative to the processing surface, and the magnet module is directly or indirectly abutted by the processing surface, the magnetic field around the magnetic induction element changes and can be detected by the magnetic induction element, thus triggering the distance detection mechanism and generating a signal indicating that the movement has reached its position. This allows for further determination of the relative distance between the processing head and the processing surface based on the relative movement distance. During this triggering process, since the detection mechanism determines whether the distance detection mechanism is triggered by detecting changes in the magnetic field, or in other words, whether the magnet module has moved, the triggering of the distance detection mechanism is less susceptible to its own production errors and assembly tolerances, ensuring that the processing head is triggered to detect the movement when the magnet module moves. Therefore, the structural design of the processing module in this solution improves the detection accuracy of the distance detection mechanism, thereby enhancing the accuracy of detecting the distance between the processing head and the processing surface. In this scheme, the magnetic induction element and the magnet module are arranged at relative intervals along the first direction, so that the two can be aligned and the magnetic induction element is fully located in the magnetic field formed by the magnet module, so as to more accurately detect the magnetic field signal formed by the magnet module and further improve the detection accuracy of the distance detection mechanism.

[0044] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] 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.

[0047] 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.

[0048] Furthermore, the use of terms such as "first" and "second" 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 those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0049] In processing equipment such as laser processing equipment and 3D printing equipment, a distance detection mechanism is typically required to detect the distance between the processing head and the processing surface. In related technologies, the distance detection mechanism includes a detector and a photoelectric sensor. The process of detecting the distance between the processing head and the processing surface can be as follows: the processing head is driven to move closer to the processing surface; after moving a certain distance, the detector comes into contact with the processing surface and is abutted, causing it to move closer to the photoelectric sensor; then, after the detector has moved a preset distance, it is sensed by the photoelectric sensor, triggering a detection signal for the processing head to stop moving. Thus, by subtracting the preset movement distance of the detector from the original movement distance, the distance between the detector and the processing surface can be represented; simultaneously, the distance between the processing head and the processing surface can be calculated using the preset distance relationship between the processing head and the detector.

[0050] However, in practical applications, it has been found that the detector and photoelectric sensor in the distance detection mechanism inevitably have manufacturing errors and assembly tolerances. This causes a discrepancy between the actual movement distance of the detector and its preset movement distance as it is abutted by the machining surface. Therefore, triggering the distance detection mechanism by detecting whether the detector has moved into position can easily lead to inaccurate triggering timing and low detection accuracy, thus affecting the accuracy of distance detection between the machining head and the machining surface.

[0051] Therefore, based on the above considerations, in order to address the problem that distance detection mechanisms in processing equipment in related technologies are easily affected by production errors and assembly tolerances, resulting in low detection accuracy and affecting the accuracy of distance detection between the processing head and the processing surface, this application proposes a novel processing module. This novel processing module sets the distance detection mechanism to include a magnetic induction element and a magnet module, so that the magnetic induction element detects whether the magnetic field changes to determine whether the distance detection mechanism has been triggered. The determination method is upgraded from judging whether the movement has moved into place to judging whether movement has occurred, thereby avoiding the influence of production errors and assembly tolerances.

[0052] In addition, it should be noted that the processing equipment used in the processing module proposed in this application can be laser processing equipment (such as laser engraving machine or laser welding machine), 3D printing equipment, cutting machine, or multi-processing equipment (such as laser and cutting multi-processing equipment). This application limits the type of processing equipment.

[0053] The structure of the processing module proposed in this application will be explained below:

[0054] Please refer to Figure 1 In one embodiment of this application, the processing module 100 proposed in this application includes a processing head 10 and a distance detection mechanism 30; the distance detection mechanism 30 includes a magnetic induction element 31 and a magnet module 33, both of which are disposed on the processing head 10 and are spaced apart from each other in a first direction; the magnet module 33 is movable relative to the magnetic induction element 31 in the first direction, and the magnetic induction element 31 is used to detect the magnetic field signal provided by the magnet module 33, so as to determine whether the distance detection mechanism 30 is triggered based on the detected change signal of the magnetic field.

[0055] The processing head 10 can be used to process a workpiece. The processing head 10 can be configured according to the type of processing equipment. For example, when the processing equipment is a laser processing equipment as described above, the processing head 10 can be a laser head for emitting a laser processing beam; when the processing equipment is a 3D printing equipment as described above, the processing head 10 can be a print head for extruding material. In some embodiments, when the processing equipment is an inkjet printing equipment, the processing head 10 can also be an inkjet print head.

[0056] The distance detection mechanism 30 can provide a magnetic field via a magnet module 33. The magnet module 33 can include a magnetic body 34 and a support member 35, as described below. The magnetic body 34 is a device made of magnetic material to provide a magnetic field. Alternatively, a portion of the magnet module 33 can be formed as a device capable of providing a magnetic field. The magnetic body 34 can be of any shape, such as a cylinder, a block, or a plate. Of course, in some embodiments, the magnet module 33 may only include the magnetic body 34. Alternatively, the entire magnet module 33 can be formed as a device capable of providing a magnetic field.

[0057] The magnetic induction element 31 can be used to detect the magnetic field signal provided by the magnet module 33, wherein the magnetic field signal includes the magnetic field strength and / or magnetic field direction. The magnetic induction element 31 can be a magnetic chip such as a 3D Hall sensor, or a common Hall sensor, or an induction coil sensor, or a fluxgate sensor, etc., capable of sensing magnetic fields. Because the magnetic induction element 31 has a magnetic field sensing element and a signal processor, it can detect external magnetic field signals through the magnetic field sensing element, and receive the signal output by the magnetic field sensing element through the signal processor, and perform a series of processes such as amplification, filtering, and analog-to-digital conversion to convert the weak magnetic field signal into an electrical signal that can be recognized and processed by subsequent circuits or devices. Therefore, the magnetic induction element 31 has the characteristics of high sensitivity and high resolution, enabling it to detect changes in weak magnetic field signals when the magnet module 33 moves relative to the magnetic induction element 31. The magnet module 33 can move relative to the magnetic induction element 31 along a first direction. This includes situations where the magnetic induction element 31 is fixedly mounted on the processing head 10, and the magnet module 33 is directly mounted on the processing head 10 along the first direction, or where the portion of the processing head 10 used to mount the magnet module 33 moves along the first direction. Alternatively, it can also include situations where the magnet module 33 is fixedly mounted on the processing head 10, and the magnetic induction element 31 is directly mounted on the processing head 10 along the first direction, or where the portion of the processing head 10 used to mount the magnetic induction element 31 moves along the first direction. In other words, when the processing head 10 moves close to the processing surface for distance measurement, either the magnetic induction element 31 or the magnet module 33 can be directly or indirectly abutted and moved by the processing surface, thus changing the distance between them. Furthermore, the first direction can be the arrangement direction of the processing head 10 and the processing surface. For example, when the processing module 100 is in normal use and installation, and the processing head 10 is above the processing surface, the magnetic induction element 31 can be positioned above the magnet module 33, or the magnet module 33 can be positioned above the magnetic induction element 31. Of course, the processing head 10 and the processing surface can also be arranged horizontally. The first direction can also be horizontal. Therefore, this application does not limit the type of the first direction. Furthermore, the distance detection mechanism 30 is mounted on the processing head 10, and can be positioned on the outside of the processing head 10 for maintenance and replacement. Alternatively, it can be at least partially positioned on the inside of the processing head 10.

[0058] The processing module 100 of this application's technical solution includes a distance detection mechanism 30 comprising a magnetic induction element 31 and a magnet module 33. The magnetic induction element 31 possesses high sensitivity and high resolution, enabling it to detect even weak changes in magnetic field signals. Simultaneously, the magnet module 33 is configured to move relative to the magnetic induction element 31 along a first direction. Therefore, when the processing head 10 moves relative to the processing surface, and the magnet module 33 is directly or indirectly abutted and driven by the processing surface, the magnetic field around the magnetic induction element 31 changes and can be detected by the magnetic induction element 31, thus determining that the distance detection mechanism 30 has been triggered, generating a signal indicating that it has moved to the correct position, thereby determining the relative distance between the processing head 10 and the processing surface. During this triggering process, since the detection mechanism determines whether the distance detection mechanism 30 has been triggered by detecting whether the magnetic field has changed, or in other words, whether the magnet module 33 has moved, the triggering of the distance detection mechanism 30 is less susceptible to its own production errors and assembly tolerances, ensuring that the processing head 10 is triggered to detect the signal indicating that it has moved to the correct position when the magnet module 33 moves. Therefore, the structural design of the processing module 100 in this solution can improve the detection accuracy of the distance detection mechanism 30, thereby improving the accuracy of detecting the distance between the processing head 10 and the processing surface. Furthermore, the distance detection mechanism 30 in this solution also arranges the magnetic induction element 31 and the magnet module 33 at relative intervals along the first direction, allowing them to be aligned and ensuring that the magnetic induction element 31 is fully positioned within the magnetic field formed by the magnet module 33. This facilitates more accurate detection of the magnetic field signal formed by the magnet module 33, further improving the detection accuracy of the distance detection mechanism 30.

[0059] Please refer to Figure 1 and Figure 2 In one embodiment of this application, a receiving cavity 10a is provided inside the processing head 10, and the magnetic induction element 31 and the magnet module 33 are at least partially disposed inside the receiving cavity 10a.

[0060] In this embodiment, when the first direction is the vertical direction as described above, the receiving cavity 10a can be located on one side of the centerline of the processing head 10 in the vertical direction, so that there is sufficient space near the edge of the processing head 10 to install and arrange the distance detection mechanism 30. Furthermore, by at least partially housing both the magnetic induction element 31 and the magnet module 33 within the receiving cavity 10a, the compactness of the distance detection mechanism 30's distribution on the processing head 10 can be improved, thereby reducing the volume of the processing head 10, improving its aesthetic appearance, and reducing the possibility of the distance detection mechanism 30 being damaged by foreign objects.

[0061] Please refer to Figure 1In one embodiment of this application, the processing head 10 may include a first structure 11 and a second structure 15. The second structure 15 is movably connected to the first structure 11 along a first direction and together with the first structure 11 forms a receiving cavity 10a. The magnetic induction element 31 and the magnet module 33 are both completely disposed within the receiving cavity 10a and are respectively fixed to the first structure 11 and the second structure 13. Since the second structure 15 can move relative to the first structure 11 along the first direction, when both the magnetic induction element 31 and the magnet module 33 are completely disposed within the receiving cavity 10a, the movement of the second structure 15 can also drive the magnetic induction element 31 or the magnet module 33 mounted on the second structure 15 to move.

[0062] Please refer to Figure 1 When the processing head 10 is a laser head as described above, the first structure 11 may include a laser head body 11A, a protective lens module 13A, and a circuit board 14. The laser head body 11A, circuit board 14, and protective lens module 13A are arranged sequentially along a first direction. The second structure 15 may be an air nozzle 15A. The air nozzle 15A, protective lens module 13A, and circuit board 14 enclose a receiving cavity 10a. The magnetic induction element 31 is mounted on the circuit board 14 to improve the convenience of electrical and mechanical connection to the magnetic induction element 31.

[0063] The laser head body 11A may include a housing 11A1 and a laser (not shown) and a focusing lens 11A3 disposed within the housing 11A1. The focusing lens 11A3 is used to focus the laser beam emitted by the laser to enhance the energy of the laser beam. A circuit board 14 may be connected to the housing 11A1 and may have a passage hole corresponding to the focusing lens 11A3 for the laser beam to pass through. The protective lens module 13A may include a base 13A1 connected to the housing 11A1 and a protective lens 13A3 disposed within the base 13A1. The protective lens 13A3 and the focusing lens 11A3 are arranged at a relative interval to prevent dust and other particles from affecting the focusing lens 11A3. The air nozzle 15A may have a channel 15b corresponding to the protective lens 13A3 for the laser beam to pass through. Meanwhile, the channel 15b can be connected to an air supply device (e.g., a jet gun or blower) so that, under the blowing action of the air supply device, the outlet of the channel 15b in the nozzle 15A can blow air toward the processing surface. The airflow from the outlet of the channel 15b in the nozzle 15A disperses the dust generated during processing, allowing the processing head 10 to perform accurate processing. On the other hand, it can also serve a heat dissipation function during processing. Furthermore, when the first direction is vertical as described above, the distance detection mechanism 30 can be positioned on one side of the focusing lens 11A3 and the channel 15b in the horizontal direction for clearance installation. Additionally, it should be noted that the first structure 11 can also consist only of the laser head body 11A and the protective mirror module 13A, with the nozzle 15A, protective mirror module 13A, and laser head body 11A forming a receiving cavity 10a. Alternatively, the nozzle 15A and protective mirror module 13A can form the receiving cavity 10a.

[0064] Additionally, when processing head 10 is a print head as described above, please refer to... Figure 3 The first structure 11 includes a printhead body 11B, a heating module 13B, and a circuit board 14. The printhead body 11B, circuit board 14, and heating module 13B are arranged sequentially along a first direction. The second structure 15 can be a nozzle 15B. The printhead body 11B may include a housing 11B1 and a traction assembly 11B3 disposed within the housing. The traction assembly 11B3 may include a motor and traction wheels that can be driven to rotate by the motor, so that external consumables are continuously transported to the heating module 13B when the two opposing traction wheels rotate. The circuit board 14 may have passage holes for the consumables to pass through. The heating module 13B may include a mounting base 13B1 and a heating element 13B3, such as an electric heating tube or electric heating wire, disposed within the mounting base 13B1, so that the consumables can be heated and melted when they are transported into the heating module 13B. The nozzle 15B may be provided with a channel 15b that communicates with the heating module 13B, so that the molten consumables can enter and then be extruded from the outlet of the channel 15b in the nozzle 15B.

[0065] Please refer to Figure 1 or Figure 3 The first structure 11 may further include a first sealing gasket 50, which is disposed between the laser head body 11A and the circuit board 14, or between the print head body 11B and the circuit board 14. This allows the first sealing gasket 50 to seal between the laser head body 11A and the circuit board 14, or between the print head body 11B and the circuit board 14. Similarly, the first structure 11 may further include a second sealing gasket 70, which is disposed between the protective mirror module 13A and the circuit board 14, or between the heating module 13B and the circuit board 14. This allows the second sealing gasket 70 to seal between the protective mirror module 13A and the circuit board 14, or between the heating module 13B and the circuit board 14. Furthermore, when circuit 14 is mounted by being clamped between laser head body 11A and protective mirror module 13A, or by print head body 11B and heating module 13B, the first sealing gasket 50 and the second sealing gasket 70 can further buffer the circuit board 14 from its sealing function, thereby reducing the possibility of damage to the circuit board 14. The first sealing gasket 50 and the second sealing gasket 70 can be made of silicone or rubber to provide good elasticity and improve the sealing effect.

[0066] Additionally, it should be noted that in other embodiments, the first structure 11 and the second structure 15 may also be two parts of the overall outer shell of the processing head 10. This application does not limit the specific objects of the first structure 11 and the second structure 15, as long as they are several different parts of the processing head 10.

[0067] Please refer to Figure 1 In one embodiment of this application, the first structure 11 is provided with a first space 13a, the second structure 15 is provided with a second space 15a, the first space 13a and the second structure 13 are arranged sequentially and connected in a first direction to form a receiving cavity 10a; at least a portion of one of the magnetic induction element 31 and the magnet module 33 is fixedly inserted into the second space 15a, and the other is provided in the first space 13a.

[0068] In this embodiment, one of the magnetic induction element 31 and the magnet module 33 is inserted and installed through the second space 15a. This simplifies the connection structure of the magnetic induction element 31 and the magnet module 33 on the second structure 15, increases the contact area between them and improves the stability of the installation of the magnetic induction element 31 and the magnet module 33 on the second structure 15, and also improves the compactness of the distribution between the magnetic induction element 31 and the magnet module 33 and the second structure 15. In this configuration, when the magnetic induction element 31 is mounted on the circuit board 14 of the first structure 11 as described above, the protective mirror module 13A and the circuit board 14 enclose a first space 10a, or the protective mirror module 13A, the circuit board 14, and the second sealing gasket 70 enclose a first space 10a; alternatively, the heating module 13B and the circuit board 14 enclose a first space 10a, or the heating module 13B, the circuit board 14, and the second sealing gasket 70 enclose a first space 10a; and the magnet module 33 can be inserted and installed in the second space 15a. Furthermore, on the projection surface in the first direction, the projected area of ​​the second space 15a can be smaller than the projected area of ​​the first space 13a, so that the cross-section of the portion of the magnet module 33 inserted and installed in the second space 15a can be set relatively small, thereby improving the convenience of connecting the magnet module 33 and the second structure 15. Of course, in other embodiments, on the projection surface in the first direction, the projected area of ​​the second space 15a can also be equal to the projected area of ​​the first space 13a.

[0069] In some embodiments, the second space 15a can be a threaded hole. The magnet module 33 and the second space 15a are threadedly connected to further simplify the connection structure of the magnet module 33 and improve the stability of the installation. The second space 15a can only penetrate the side of the second structure 15 facing the first structure 11, or it can further penetrate the side of the second structure 15 facing away from the first structure 13. In addition, in some embodiments, the magnet module 33 and the second space 15a can also be connected by a snap-fit ​​connection or an interference fit connection. Alternatively, in some embodiments, the magnet module 33 can be directly connected to the surface of the second structure 15.

[0070] Please refer to the reference. Figure 1 or Figure 3 In one embodiment of this application, the magnet module 30 may include a magnetic body 34 and a carrier 35. One end of the carrier 35 is fixedly inserted into the second space 15a. The magnetic body 34 is mounted on the end of the carrier 35 facing the magnetic induction element 31 and is used to provide a magnetic field signal. The carrier 35 facilitates connection and cooperation with the second space 15a, and the connection with the second space 15a does not easily damage the structure of the magnetic body 34 itself.

[0071] In some embodiments, the support member 35 may include a base portion 351 and a rod portion 353, one end of the rod portion 353 is fixedly inserted into the second space 15a, and the other end extends into the first space 13a; the base portion 351 is connected to the rod portion 353 located in the first space 13a, and the magnetic member 34 is installed on the base portion 351.

[0072] In this embodiment, on the projection plane in the first direction, the projection of the rod portion 353 can be located inside the projection of the base portion 351. This allows the base portion 351, with its larger cross-section, to provide a sufficiently large mounting position for the magnetic body 34, while the rod portion 353, with its smaller cross-section, can improve the compactness of the connection between the second space 15a on the second structure 15. Furthermore, a step can be formed at the connection between the base portion 351 and the rod portion 353. This allows the step to abut and limit the contact between the support member 35 and the side of the second structure 15 facing the first structure 11 when the support member 35 is installed into the second space 15a on the second structure 15.

[0073] In some embodiments, the base portion 351 may be provided with a fixing groove 351a, and the magnetic body 34 is installed in the fixing groove 351a. By providing a fixing groove 351a on the base portion 351, the magnetic body 34 can be adapted to be installed. This eliminates the need for a connecting structure on the magnetic body 34, thereby improving the convenience of installing the magnetic body 34 and ensuring that the structure of the magnetic body 34 itself is not easily damaged. Of course, in other embodiments, the magnetic body 34 can also be fixed to the surface of the base portion 351 by means of bonding or other methods. In addition, in some embodiments, the carrier 35 may only include the base portion 351 or the rod portion 353.

[0074] Please refer to Figure 1 In one embodiment of this application, the second structure 15 and the first structure 11 are spaced apart and magnetically connected in a first direction. The processing module 100 also includes a first elastic member 90, which is disposed between the first structure 11 and the second structure 15.

[0075] In this embodiment, the first structure 11 and the second structure 15 are spaced apart, and a first elastic member 90 is provided between them. This allows the second structure 15 to abut against the processing surface when the processing head 10 moves a detection distance closer to the processing surface, causing the second structure 15 to be squeezed and move, thereby indirectly moving the magnet module 33 mounted on the second structure 15. Simultaneously, the first elastic member 90 can also automatically reset the second structure 15 after it separates from the processing surface, allowing for normal distance detection in the next operation. Furthermore, the magnetic connection between the second structure 15 and the first structure 11 simplifies the connection and minimizes the impact on the movement of the second structure 15. The second structure 15 and the first structure 11 can be equipped with magnets that attract each other, or one can have a magnet and the other a metal that can be attracted by a magnet. Additionally, when the processing module 100 is a laser head as described above, the first elastic member 90 can be positioned between the protective lens module 13A and the air nozzle 15A. When the processing module 100 is a printhead as described above, the first elastic element 90 can be disposed between the heating module 13B and the nozzle 15B.

[0076] In some embodiments, please refer to Figure 1 The first elastic member 90 can be a ring-shaped structure and is disposed around the channel 15b of the second structure 15 near the opening of the channel 15b at one end of the first structure 11. The first elastic member 90 can be made of soft rubber so that it can not only move and reset the second structure 15, but also allow the second structure 15 to move relative to the first structure 11 instead of being rigidly connected, and also provide a sealing effect between the second structure 15 and the first structure 11. This achieves at least three functions with one structure, thereby simplifying the structural design of the processing head 10. The first elastic member 90 can include a body portion 91 and a protrusion portion 93. The body portion 91 is disposed around the channel 15b, and the protrusion portion 93 protrudes from the side of the body portion 91 facing the first structure 11 and contacts the first structure 11. In this way, the body portion 91 can be easily connected to the second structure 15, while the protrusion portion 93 can be compressed and deformed to achieve the mobility of the second structure 15 in the first direction and the sealing between the first structure 11 and the second structure 15. Of course, in some embodiments, the first elastic element 90 may also serve as a reset element on its own. The second elastic element 90 may be a spring or a sheet.

[0077] Additionally, it should be noted that when the processing head 10 is the print head as described above, the temperature is relatively high because the first structure 15 in the print head includes a heating module 13B. Therefore, when the second structure 15 is movably connected to the first structure 11, the first elastic element 90 can be made of a high-temperature resistant material, such as fluororubber or silicone rubber.

[0078] Please refer to Figure 1 In one embodiment of this application, the second structure 15 is provided with an abutment protrusion 151 on the side opposite to the first structure 11.

[0079] In this embodiment, the abutment protrusion 151 can be located at the lowest position of the processing head 10. The abutment protrusion 151 facilitates early contact with the processing surface, improving distance detection efficiency. At the same time, it can also reduce the possibility of damage to the second structure 15. The abutment protrusion 151 can be a cylindrical structure, and a rounded corner can be provided at the end away from the second structure 15 to reduce the possibility of damage to the processing surface.

[0080] Please refer to Figure 2 In one embodiment of this application, the second structure 15 may also be fixedly connected to the first structure 11. Specifically, it may be connected by any connection method such as screw connection or snap connection. This application does not limit the connection method between the first structure 11 and the second structure 15.

[0081] One of the magnetic induction element 31 and the magnet module 33 is completely disposed within the receiving cavity 10a, while the other is movable within the receiving cavity 10a along the first direction and partially extends through the processing head 10 to the outside of the receiving cavity 10a to abut against the processing surface. Thus, the connection between the second structure 15 and the first structure 11 is less affected by the movable arrangement of one of the magnetic induction element 31 and the magnet module 33, thereby facilitating the sealing effect between the second structure 15 and the first structure 13.

[0082] Please refer to Figure 2 or Figure 3 The end of the rod portion 353 of the carrier 35 in the magnet module 33 away from the slot opening of the fixing groove 351a can be movably inserted into the second space 15a and pass through the second space 15a to the outside of the second structure 15, so that the end of the rod portion 353 away from the seat portion 351 can be located at the lowest position of the processing head 10.

[0083] In this embodiment, the rod portion 353 is movably inserted into the second space 15a, which simplifies the movable installation structure between the rod portion 353 and the second structure 15, thereby improving the convenience of moving and installing the rod portion 353. Furthermore, the second space 15a also guides the movement of the rod portion 353, improving the stability of its movement and the accuracy of triggering the distance detection mechanism 30. Further, by extending one end of the rod portion 353 through the second space 15a to the outside of the second structure 15, it is convenient that when the processing head 10 moves towards the processing surface, the rod portion 353 can first contact the processing surface, thus triggering the distance detection mechanism 30 promptly and effectively. Alternatively, a groove can be provided on the second structure 15, and a slider can be provided on the rod portion 353, with the slider sliding in conjunction with the groove to achieve the sliding installation of the rod portion 353 on the second structure 15.

[0084] In some embodiments, the second space 15a can be a light aperture, and the distance detection mechanism 30 further includes a second elastic member 37. The second elastic member 37 is disposed in the second space 15a and located between the magnet module 33 and the second module. The second elastic member 37 is used to drive the magnet module 33 to move and reset when the external force is removed from the magnet module 33 that extends to the outside of the receiving cavity 10a.

[0085] The hole, that is, the hole wall of the second space 15a, is smooth and has no threads. The second elastic element 37 can be a spring, or of course, a sheet, a silicone ring, etc.

[0086] In this embodiment, by providing a second elastic element 37, during the distance detection process where the processing head 10 approaches the processing surface, the rod portion 353 contacts the processing surface and is abutted and driven, pressing against the second elastic element 37, causing the second elastic element 37 to form a deformation elastic force. After the processing head 10 completes the distance detection, the rod portion 353 separates from the processing surface and can be automatically reset under the drive of the deformation elastic force of the second elastic element 37, so that the distance detection mechanism 30 can be used normally next time.

[0087] Please refer to Figure 2 or Figure 3 In one embodiment of this application, the rod portion 353 located in the second space 15a is provided with a first limiting protrusion 3531, and the second structure 15 is provided with a second limiting protrusion 15a1 in the second space 15a; the second elastic member 37 is sleeved on the rod portion 353, and the two ends of the second elastic member 37 are respectively connected to the first limiting protrusion 3531 and the second limiting protrusion 15a1.

[0088] In this embodiment, the second elastic member 37 is sleeved and installed on the outside of the rod body 353, which can improve the compactness of the distance detection mechanism 30 and guide the direction of the elastic force of the second elastic member 37. The first limiting protrusion 3531 and the second limiting protrusion 15a1 can facilitate the connection between the connecting position and the second elastic member 37. The first limiting protrusion 3531 can be arranged around the circumference of the rod body 353 to form a ring structure, and the second limiting protrusion 15a1 can also be arranged around the circumference of the second space 15a to form a ring structure, so as to facilitate effective and stable contact with the first elastic member 37. Of course, in other embodiments, the first limiting protrusion 3531 and the second limiting protrusion 15a1 can also be a block structure or an arc-shaped plate structure. In addition, the second elastic member 37 can also be disposed between the second limiting protrusion 15a1 and the seat body 351.

The processing module 100 may be installed on the track device 300. The track device 300 may include a first track device 301 and a second track device 302 connected to the first track device 301.

[0091] At least two first track devices 301 can be provided and arranged intersectingly to drive the processing module 100 to move in two intersecting horizontal directions, namely, the second direction and the third direction intersecting the first direction as shown in the figure. The track device 301 can be a pulley drive (i.e., a combination of pulleys and belts) or a sprocket drive (i.e., a combination of sprockets and chains). This application does not limit the drive method of the track device 301, as long as it can drive the processing module 100.
