[0086] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0087] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0089] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0090] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0091] The embodiment of the present application provides a method for disassembling a chuck 20 of a circuit board processing device 100, such as Figure 1 and Figure 2 As shown, the circuit board processing equipment 100 includes a body 40, the body 40 is provided with a spindle 30 and a replacement device 10, and the spindle 30 is provided with a chuck 20, as shown in FIG. Figure 10 As shown, the replacement device 10 includes a replacement assembly 13, which is provided with grooves or protrusions, and the chuck 20 is provided with corresponding protrusions or grooves. The replacement device 10 also includes a third mounting plate 15 for mounting the replacement device 10 on the machine body 40.

[0092] like Figure 12 and Figures 3 to 7 As shown, the method of disassembling the chuck 20 includes:

[0093] S1 : Control the changing device to move below the main shaft 30 or control the main shaft 30 to move above the changing device 10 .

[0094] S2: Control the main shaft 30 to descend, and control the replacement component 13 to rise until the protrusion of the chuck 20 extends into the groove of the replacement component 13 or the protrusion of the replacement component 13 extends into the groove of the chuck 20.

[0095] In this step, the protrusion can extend into the groove, so that the replacement component 13 drives the chuck 20 to rotate through the cooperation of the protrusion and the groove. Specifically, when the replacement component 13 is provided with a groove, the chuck 20 is correspondingly provided with a protrusion, and when the replacement component 13 is provided with a protrusion, the chuck 20 is correspondingly provided with a groove.

[0096] S3: Control the replacement assembly 13 to drive the chuck 20 to rotate so as to remove the chuck 20 from the spindle 30.

[0097] In this embodiment, the replacement device 10 is used to disassemble the chuck 20 without the need for direct operator intervention, resulting in rapid and efficient disassembly, ensuring worker safety and saving human resources. Furthermore, the disassembly process of the replacement device 10 is standardized, improving the quality and reliability of the disassembly operation.

[0098] Specifically, the circuit board processing equipment 100 may be a molding machine, etc.

[0099] The main shaft 30 may be provided with screws or other connecting parts, and the chuck 20 may be provided with threaded holes, so that the main shaft 30 and the chuck 20 can be firmly connected by the cooperation between the screws and the threaded holes. Figure 10 As shown, the replacement assembly 13 also includes a guide pin 132, which is installed in the groove or protrusion of the operating part 131 and is used to cooperate with the guide hole on the protrusion or groove of the chuck 20. When the operating part 131 contacts the chuck 20, the guide pin 132 can extend into the guide hole on the chuck 20, guiding the protrusion to cooperate smoothly with the groove, thereby playing a role in positioning and guiding the chuck 20. More specifically, as shown in FIG. Figure 11 As shown, the operating portion 131 is provided with a mounting hole 131 b for mounting the guide pin 132 , and the mounting hole 131 b is provided at the center of the groove 131 a .

[0100] In a specific embodiment, Figure 10 As shown, the replacement device 10 also includes a first drive component 11 and a second drive component 12, and the replacement component 13 includes an operating part 131. The groove or protrusion of the replacement component 13 is provided on the operating part 131. Among them, the first drive component 11 can drive the replacement component 13 to move, and the second drive component 12 can drive the operating part 131 to rotate. The cross-section of the groove and the protrusion is polygonal, so that when the groove and the protrusion cooperate, the protrusion cannot rotate relative to the groove, so that when one of the operating part 131 and the chuck 20 is provided with a protrusion and the other is provided with a groove, the operating part 131 can drive the chuck 20 to rotate by its own rotation. Specifically, as shown in FIG. Figure 11 As shown, the operating portion 131 may be provided with a groove 131 a having a hexagonal cross section, and the chuck 20 may be provided with a protrusion having a hexagonal cross section correspondingly.

[0101] As a way to implement Figure 10 As shown, the first drive assembly 11 includes a cylinder 111 and a second mounting plate 112. The cylinder 111 includes a piston rod 111a, a cylinder body 111b, and a guide rod 111c. The piston rod 111a is connected to the second mounting plate 112. At least a portion of the replacement assembly 13 is disposed on the second mounting plate 112. The cylinder 111 can drive the second mounting plate 112 to move via the piston rod 111a, thereby moving the replacement assembly 13. The guide rod 111c is connected to the second mounting plate 112, and a linear guide component (linear bearing or linear bushing) mounted on the cylinder body 111b enables the piston rod 111a to move up and down stably. The cylinder 111 also includes an air circuit interface 111d, through which gas is introduced to drive the piston rod 111a to move.

[0102] As a way to implement Figure 10As shown, the second drive assembly 12 includes a motor 121 and a reducer 122, and the operating portion 131 is connected to the output shaft of the reducer 122, thereby enabling the second drive assembly 12 to drive the operating portion 131 to rotate. The motor 121 and the reducer 122 cooperate to output a large torque, ensuring that the replacement device 10 can remove or install the chuck 20. At least a portion of the second drive assembly 12 is disposed within the inner cavity of the cylinder 111b, thereby reducing the volume of the replacement device 10. The second drive assembly 12 can also be implemented directly using a motor capable of outputting a large torque, or using a torque-adjustable rotation unit such as a pneumatic or hydraulic unit.

[0103] like Figure 13 As shown, S2: controlling the replacement component 13 to rise until the protrusion of the chuck 20 extends into the groove of the replacement component 13 or the protrusion of the replacement component 13 extends into the groove of the chuck 20, the method for removing the chuck 20 includes:

[0104] S21 : Control the first driving assembly 11 to drive the replacement assembly 13 to rise and abut against the chuck 20 .

[0105] In this step, since the cross-sections of the groove and the protrusion are polygonal, when the replacement component 13 rises and abuts the chuck 20, the sides of the protrusion do not correspond to the sides of the groove and cannot extend into the groove.

[0106] S22 : Control the second driving component 12 to rotate the operating portion 131 with the first torque, so that the protrusion of the chuck 20 extends into the groove of the replacement component 13 or the protrusion of the replacement component 13 extends into the groove of the chuck 20 .

[0107] In this step, when the second drive assembly 12 drives the operating portion 131 to rotate with the first torque, the operating portion 131 rotates slowly. When the edges of the protrusions correspond to the edges of the grooves, the protrusions extend into the grooves, thereby driving the chuck 20 to rotate when the operating portion 131 rotates. Specifically, the magnitude of the first torque is preferably 0.6 to 0.8 N·m.

[0108] In addition, the replacement assembly 13 also includes a cover plate 133, which is mounted on the first drive assembly 11. The cover plate 133 is provided with a first through-hole 133a, through which the operating portion 131 passes. The diameter of the first through-hole 133a is larger than the diameter of the operating portion 131, allowing the operating portion 131 to move relative to the cover plate 133. The lower surface of the cover plate 133 is also provided with a receiving groove 133b. The replacement assembly 13 also includes a first mounting plate 134 located below the cover plate 133. At least a portion of the first mounting plate 134 can be mounted in the receiving groove 133b. The first mounting plate 134 is provided with a second through-hole 134a, through which the operating portion 131 passes. When the first mounting plate 134 is installed in the receiving groove 133b, a gap exists between the circumferential edge of the first mounting plate 134 and the sidewall of the receiving groove 133b, allowing the first mounting plate 134 to move relative to the cover plate 133 to accommodate assembly errors. This allows the protrusion to mate with the groove even when the replacement device 10 deviates slightly from the position directly below the spindle 30, thereby improving the reliability of the replacement device 10. Specifically, the receiving groove 133b and the first mounting plate 134 can be rectangular, circular, or other shapes.

[0109] In a specific embodiment, Figure 10 As shown, the replacement device 10 further includes a sensor 141 and a controller. The sensor 141 is installed on the first drive assembly 11, and the controller is set on the body 40. The sensor 141 can sense the cover plate 133 when the cover plate 133 drops to the lowest point to determine whether the protrusion and the groove are matched. Figure 8 and Figure 9 As shown, in Figure 8 The middle cover 133 is at the lowest point. Figure 9 The middle cover plate 133 rises under the drive of the first driving assembly 11 .

[0110] If the protrusion of the chuck 20 fails to extend into the groove of the replacement component 13 or the protrusion of the replacement component 13 fails to extend into the groove of the chuck 20, the sensor 141 detects the replacement component 13 and generates an error message and sends it to the controller.

[0111] In this embodiment, during the process of the replacement component 13 rising, if the operating part 131 deviates too much from the main shaft 30, the operating part 131 or the guide pin 132 will abut against a part other than the protrusion or groove on the chuck 20, or even the operating part 131 as a whole deviates from the chuck 20 and abuts against the body 40 of the circuit board processing equipment 100, resulting in the guide pin 132 being unable to extend into the guide hole and the protrusion being unable to extend into the groove, so that the replacement device 10 cannot operate the chuck 20. At this time, the replacement component 13 cannot rise normally, and the sensor 141 senses that the cover 133 stays at the lowest point for a long time, and generates an error message and sends it to the controller. The controller issues an alarm or transmits an error message to the on-site staff, prompting the on-site staff that there is an abnormality in the replacement device 10 so that it can be dealt with in time to prevent damage to the circuit board processing equipment 100.

[0112] In addition, the sensing object of the sensor can also be set to other components of the replacement component 13 or components that move up and down with the replacement component 13. The replacement device 10 also includes a mounting base 142, and the sensor 141 can be mounted on the first driving component 11 through the mounting base 142.

[0113] In a specific embodiment, Figure 13 As shown, S3: controlling the replacement component 13 to drive the chuck 20 to rotate to remove the chuck 20 from the spindle 30 specifically includes:

[0114] S31 : Controlling the second driving assembly 12 to drive the operating part 131 to rotate by a first preset angle or a first preset duration with a second torque.

[0115] In this step, since the chuck 20 and the spindle 30 are locked, a relatively large torque is required to rotate the chuck 20 relative to the spindle 30. Therefore, the second torque is preferably 2.5 to 3.5 N·m. The first preset angle or first preset duration is determined based on the angle or duration required to loosen the chuck 20.

[0116] S32: Control the second driving assembly 12 to drive the operating part 131 to rotate by a second preset angle or a second preset time period with a third torque, wherein the third torque is smaller than the second torque.

[0117] In this step, after the chuck 20 rotates through a certain angle, the chuck 20 and the spindle 30 are no longer in a locked state, but the chuck 20 has not yet separated from the spindle 30. At this time, if the chuck 20 is still driven to rotate with the second torque, the spindle 30 may be worn or damaged due to excessive force acting on the spindle 30. Therefore, after the chuck 20 rotates through the first preset angle, driving the chuck 20 with the third torque can reduce the force applied by the chuck 20 on the spindle 30, reduce the wear on the spindle 30 caused by chuck replacement, and extend the life of the spindle 30. The magnitude of the third torque is preferably 1.0 to 2.0 N·m. The second preset angle or second preset duration is determined by the angle or duration required for the chuck 20 to rotate from being loosened to completely disconnected from the spindle 30 (i.e., the chuck 20 and the spindle 30 are no longer threaded, but at least a portion of the connector is still located in the threaded hole of the chuck).

[0118] S33 : Control the first driving assembly 11 to drive the replacement assembly 13 to descend so as to separate the chuck 20 from the spindle 30 .

[0119] In this step, after the chuck 20 rotates the first preset angle and the second preset angle respectively or after the chuck 20 rotates the first preset time length and the second preset time length, the chuck 20 and the spindle 30 are disconnected. At this time, the replacement component 13 is directly driven to carry the chuck 20 downward to separate the chuck 20 from the spindle 30, thereby realizing the removal of the chuck 20 from the spindle 30.

[0120] In a specific embodiment, the thrust applied by the first drive component 11 to the replacement component 13 is greater than the gravity of the replacement component 13 and less than the sum of the gravity of the replacement component 13 and the chuck 20, so that the replacement component 13 can move with the chuck 20 and keep the groove of the replacement component 13 matched with the protrusion of the chuck 20 or the protrusion of the replacement component 13 matched with the groove of the chuck 20.

[0121] In this embodiment, when the thrust applied by the first drive component 11 to the replacement component 13 is greater than the gravity of the replacement component 13, the replacement component 13 has a tendency to rise, and the protrusion and the groove are in an extruded state. At the same time, when the thrust applied by the first drive component 11 to the replacement component 13 is less than the sum of the gravity of the replacement component 13 and the chuck 20, as the locking state of the chuck 20 and the main shaft 30 is released, the replacement component 13 slowly descends as the chuck 20 is continuously removed, thereby preventing the excessive force between the chuck 20 and the main shaft 30 from wearing the main shaft 30.

[0122] In a specific embodiment, the circuit board processing equipment 100 is provided with a detection component, which can be provided on the main spindle 30 to detect whether the chuck 20 is installed on the main spindle 30 .

[0123] like Figure 13As shown, S1: before controlling the replacement device 10 to move below the spindle 30 or controlling the spindle 30 to move above the replacement device 10, the method for disassembling the chuck 20 includes:

[0124] S0: The detection component is controlled to detect whether the chuck 20 is installed on the main shaft 30.

[0125] If the chuck 20 is mounted on the main spindle 30 , then S1 : control the changing device 10 to move to the bottom of the main spindle 30 or control the main spindle 30 to move to the top of the changing device 10 .

[0126] If the chuck 20 is not installed on the spindle 30 , S4 : the step of removing the chuck 20 is stopped.

[0127] In this embodiment, before performing the step of removing the chuck 20, detecting whether the chuck 20 is installed on the main shaft 30 by a detection part can prevent the operation of removing the chuck 20 from being performed when the chuck 20 is not installed on the main shaft 30, thereby preventing the replacement device 10 from working abnormally, making the circuit board processing equipment 100 more intelligent, and improving the reliability of the circuit board processing equipment 100 in removing the chuck 20.

[0128] The embodiment of the present application also provides a method for installing the chuck 20 of the circuit board processing equipment 100, such as Figure 1 and Figure 2 As shown, the circuit board processing equipment 100 includes a body 40, a spindle 30, a chuck 20 and a replacement device 10. The spindle 30 and the replacement device 10 are arranged on the body 40. The spindle 30 is provided with a connecting piece, and the chuck 20 is provided with a mounting hole adapted to the connecting piece.

[0129] like Figure 14 As shown, the method of installing the chuck 20 includes:

[0130] P1: Control the replacement device provided with the collet 20 to move to the bottom of the main spindle 30 or control the main spindle 30 to move to the top of the replacement device 10 provided with the collet 20 .

[0131] P2: Control the main shaft 30 to descend so that the connecting piece fits with the mounting hole.

[0132] In this step, the main shaft 30 is lowered so that the connecting piece of the main shaft 30 for connecting with the chuck 20 extends into the mounting hole of the chuck 20 .

[0133] P3: Control the replacement device to drive the chuck 20 to rotate and install the chuck 20 on the spindle 30.

[0134] In this step, both the connecting piece and the mounting hole are provided with threads, and the chuck 20 and the main shaft 30 can be locked by the chuck 20 .

[0135] In this embodiment, the installation of the chuck 20 is achieved by replacing the device 10. On the one hand, it ensures that the locking degree of the chuck 20 and the spindle 30 is the same each time the chuck 20 is installed, thereby preventing the spindle 30 from being damaged due to the chuck 20 being installed too tightly or the processing performance of the circuit board processing equipment 100 from being affected by the chuck 20 being installed too loosely. On the other hand, there is no need to manually replace the chuck 20, the replacement speed is fast, the efficiency is high, and manpower is saved.

[0136] In a specific embodiment, Figure 10 As shown, the changing device 10 comprises a second drive assembly 12 .

[0137] like Figure 15 As shown, P3: Control the replacement device 10 to drive the chuck 20 to rotate. When the chuck 20 is installed on the spindle 30, the method of installing the chuck 20 includes:

[0138] P31 : Control the second driving assembly 12 to drive the chuck 20 to rotate by a third preset angle or for a third preset time using a fourth torque, so that the chuck 20 is installed on the spindle 30 .

[0139] In this embodiment, the chuck 20 is driven by the second drive assembly 12 to rotate by a third preset angle or for a third preset duration to ensure that the chuck 20 is locked with the spindle 30. The magnitude of the fourth torque can be 0.6 to 1.5 N·m, preferably 1.0 N·m, to ensure that the torque applied to the chuck 20 is sufficient to lock the chuck 20 with the spindle 30 without damaging the spindle 30.

[0140] In a specific embodiment, the thrust applied by the first drive component 11 to the replacement component 13 is greater than the sum of the gravity of the replacement component 13 and the chuck 20, so that the replacement component 13 can move with the chuck 20, keeping the groove of the replacement component 13 matched with the protrusion of the chuck 20 or the protrusion of the replacement component 13 matched with the groove of the chuck 20.

[0141] In this embodiment, when the thrust applied by the first drive assembly 11 to the replacement assembly 13 is greater than the combined weight of the replacement assembly 13 and the chuck 20, the replacement assembly 13 can carry the chuck 20 upward, thereby causing the protrusion and the groove to engage in a squeezed state, thereby facilitating the installation of the chuck 20 on the spindle 30. At the same time, the chuck 20 continuously rises during the installation process, and the replacement assembly 13 can slowly rise along with the installation process of the chuck 20, thereby ensuring the reliability of the replacement assembly 13 in installing the chuck 20.

[0142] In a specific embodiment, a detection member is provided on the main shaft 30 . The detection member can be provided on the main shaft 30 to detect whether the chuck 20 is installed on the main shaft 30 .

[0143] like Figure 15As shown, P1: before controlling the replacement device 10 provided with the chuck 20 to move to the bottom of the spindle 30 or the spindle 30 to move to the top of the replacement device 10 provided with the chuck 20, the method for installing the chuck 20 includes:

[0144] P0: The control detection component detects whether the chuck 20 is installed on the spindle 30;

[0145] If the chuck 20 is installed on the spindle 30, then P4: stop the step of installing the chuck 20;

[0146] If the chuck 20 is not installed on the spindle 30 , then P1 : control the replacement device 10 provided with the chuck 20 to move to the bottom of the spindle 30 or the spindle 30 to move to the top of the replacement device 10 provided with the chuck 20 .

[0147] In this embodiment, before performing the step of installing the chuck 20, detecting whether the chuck 20 is installed on the main shaft 30 by using a detection part can prevent the operation of installing the chuck 20 from being performed when the chuck 20 is already installed on the main shaft 30, thereby preventing the replacement device 10 from working abnormally, making the circuit board processing equipment 100 more intelligent, and improving the reliability of the circuit board processing equipment 100 in installing the chuck 20.

[0148] In addition, the circuit board processing equipment 100 can continuously perform the steps of removing the collet 20 and installing the collet 20, thereby realizing the replacement of the collet 20 of the circuit board processing equipment 100. Specifically, after the collet 20 is removed from the spindle 30, the replacement device 10 carries the removed collet 20 and moves to the edge of the machine body 40 (such as Figure 1 As shown), a worker or other mechanism removes the disassembled chuck 20 from the replacement device 10, and then places a new chuck 20 or a maintained chuck 20 on the replacement device 10. The replacement device 10 carries the chuck 20 and moves to the bottom of the spindle 30 for installation (as shown). Figure 3 As shown), thereby achieving the replacement of the chuck 20. In addition, as Figure 8 As shown, the guide pin 132 installed in the mounting hole 131b protrudes from the upper surface of the operating part 131, so that the guide pin 132 can extend into the interior of the chuck 20 with a longer length, making it difficult for the chuck 20 to separate from the replacement component 13 during the movement with the replacement component 13, preventing the chuck 20 from falling from the replacement component 13 and being damaged, thereby improving the reliability of the replacement device 10 during the replacement operation.

[0149] In a specific embodiment, Figure 1 and Figure 2 As shown, a plurality of spindles 30 and a plurality of replacement devices 10 are provided on the machine body, and the plurality of replacement devices 10 can remove a plurality of chucks 20 .

[0150] In this embodiment, if Figure 1 and Figure 2 As shown, multiple spindles 30 are provided on a machine body 40, each of which is equipped with a chuck 20. This can improve the processing speed of the circuit board processing equipment 100. Multiple replacement devices 10 are provided corresponding to the multiple spindles 30, allowing the replacement devices 10 to replace multiple chucks 20, reducing the time required to replace chucks 20, thereby reducing the downtime of the circuit board processing equipment 100 and improving the production efficiency of the circuit board processing equipment 100. In addition, the replacement device 10 can also replace one or more chucks 20 individually depending on the condition of the chuck 20.
