[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figures 1 to 4 As shown, an embodiment of the present invention provides a PCB processing device, wherein the PCB processing device can be a drilling machine, a forming machine or a drilling and gonging machine, etc. The PCB processing device includes a main body, a rubber tapping device 1 and a positioning device 2, the main body includes a spindle device 3 and a processing table 4, the spindle device 3 is arranged above the processing table 4, and the positioning device 2 is arranged on the spindle device 3; the processing table 4 has a processing station and a rubber tapping station, the spindle device 3 can be moved to the processing station, and the rubber tapping device 1 is arranged at the rubber tapping station; After the spindle device 3 completes the processing of the PCB board 5 at the processing station, the rubber tapping device 1 can tap the PCB board 5. In some embodiments, the rubber tapping device 1 can move to tap the PCB board 5. In the present embodiment, the PCB board 5 can be moved to the rubber tapping station, for example, the PCB board 5 is transferred to the rubber tapping station by the mobile platform on the processing table 4, and then the rubber tapping device 1 taps the PCB board 5 located at the rubber tapping station. The position of the rubber tapping station is not limited, and the rubber tapping station can be located on either side of the processing station, as long as the PCB board 5 can be moved from the processing station to the rubber tapping station. The spindle device 3 can switch between the processing station and the non-processing station. When the spindle device 3 moves to the processing station, the PCB board 5 in the processing station can be processed, and the PCB board 5 after the processing is completed can be moved to the rubber tapping station. The rubber tapping device 1 can switch between the rubber tapping state and the non-tapping state. When the rubber tapping device 1 switches to the rubber tapping state, the tape on the PCB board 5 of the rubber tapping station can be cut. Along the first direction, the processing station and the rubber tapping station are arranged in sequence, and the processing station is suitable for placing the PCB board 5. The first direction is the conveying direction of the conveying device 6. The PCB board 5 is stacked in sequence by a pad, a PCB board and an aluminum plate, and then connected in series by a positioning pin 51, and then the aluminum sheet on the surface and the bottom pad are adhered together by an adhesive tape to form a combined plate. The spindle device 3 and the rubber tapping device 1 are both electrically connected to the control system, and the control system controls the movement of the spindle device 3 and the rubber tapping device 1. The control system is a PLC or other type of control board. The spindle device 3 includes a motor, a spindle body, a drill needle and a presser foot. The drill needle is installed on the spindle body and passes through the inner hole of the presser foot. The motor is electrically connected to the control system, and the rotation of the spindle body is driven by the rotation of the motor. By integrating the rubber tapping device 1 with the processing table 4, the demand for additional rubber tapping equipment is reduced, thereby reducing the overall equipment investment cost. The PCB board 5 can be quickly moved to the rubber tapping station after completing the processing, reducing the waiting time and the transfer time, thereby speeding up the entire production process. At the same time, processing and tapping operations on the same equipment can ensure that the position and direction of the PCB board 5 remain consistent, reduce errors that may occur during the transfer process, and improve processing accuracy. Figure 1 In the figure, X represents the first direction, Y represents the second direction, and Z represents the third direction.

[0024] In one embodiment, the PCB processing equipment further comprises a positioning member withdrawal device 2, the positioning member withdrawal device 2 is connected to the spindle device 3, the processing table 4 is provided with a receiving hole, and the PCB board 5 is provided with a positioning pin 51, and the positioning member withdrawal device 2 can abut the positioning pin 51 of the PCB board 5 and push the positioning pin 51 into the receiving hole. In this embodiment, the integrated design of the positioning member withdrawal device 2 and the spindle device 3 allows for rapid switching between the processing and rubber tapping processes, reducing the transfer time of the PCB board 5 between different processes. Processing and positioning member withdrawal operations are performed on the same equipment, which can ensure that the position and direction of the PCB board remain consistent, reduce errors that may occur during the transfer process, and improve processing accuracy. The positioning member device 2 can switch between the positioning member withdrawal station and the non-positioning member withdrawal station. When the positioning member withdrawal device 2 moves to the positioning member withdrawal station, the positioning member withdrawal device 2 can abut the positioning pin 51 of the PCB board 5. Among them, the processing station and the locating member withdrawal station do not overlap each other. When the PCB board 5 is processed and the locating member withdrawal process is performed, the spindle device 3 can move in the X, Y, and Z directions so that the spindle device 3 can move to the processing station and the non-processing station. At the same time, the movement of the spindle device 3 can drive the locating member withdrawal device 2 set on the spindle device 3 to move to the locating member withdrawal station and the non-locating member withdrawal station. The mechanism for driving the spindle device 3 to move can be a gantry hammock, a mechanical arm or other driving mechanism. In this embodiment, the locating member withdrawal device 2 can be electrically connected to the control system, or it can not be electrically connected to the control system. When the locating member withdrawal device 2 is not electrically connected to the control device, the control system controls the spindle device 3 to drive the locating member withdrawal device 2 to move to the locating member withdrawal station so that the locating member withdrawal device 2 abuts against the locating pin 51 of the PCB board 5, and then the control system controls the spindle device 3 to move downward along the Z direction so that the locating member withdrawal device 2 pushes the locating pin 51 into the receiving hole. When the positioning member withdrawal device 2 is electrically connected to the control system, the control system controls the spindle device 3 to drive the positioning member withdrawal machine 2 to move to the positioning member withdrawal position so that the positioning member withdrawal device 2 abuts against the positioning pin 51 of the PCB board 5, and then the control system controls the output end of the positioning member withdrawal device 2 to move downward along the Z direction, so that the positioning member withdrawal device 2 pushes the positioning pin 51 into the receiving hole. At the same time, the spindle device 3 and the positioning member withdrawal device 2 both have a processing position and an avoidance position. When processing is performed, the spindle device 3 is located at the processing position, and the positioning member withdrawal device 2 is located at the avoidance position. When the positioning member withdrawal process is performed, the spindle device 3 is located at the avoidance position, and the positioning member withdrawal device 2 is located at the processing position, which can prevent the positioning member withdrawal device 2 from interfering with and colliding with the PCB board 5 during processing; and during the positioning member withdrawal process, the spindle device 3 is prevented from interfering with and colliding with the PCB board 5, wherein the avoidance position can be achieved by setting a hollow structure on the processing table 4. When the PCB board 5 requires multiple processing, the processing station of the present application includes multiple coordinate values. When the PCB board 5 has multiple positioning pins 51, the positioning member withdrawal station includes multiple coordinate values.In addition, the processing table 4 also has a positioning member withdrawal station, which can overlap with the processing station or be located at a different position from the processing station.

[0025] In one embodiment, the locating member withdrawal device 2 includes a first drive assembly 21 and a pin 22. The first drive assembly 21 is arranged on the spindle device 3, and the pin 22 is installed at the output end of the first drive assembly 21. The first drive assembly 21 can drive the pin 22 to push the locating pin 51 of the PCB board 5 into the receiving hole. In this embodiment, the first drive assembly 21 is electrically connected to the control system. When the locating member withdrawal process is performed, the control system controls the spindle device 3 to move, drive the locating member withdrawal device 2 to move to the locating member withdrawal station, and the position of the spindle device 3 remains unchanged. Then, the control system controls the output end of the locating member withdrawal device 2 to drive the locating member device to push the locating pin 51 into the receiving hole. During the locating member withdrawal process, this can prevent the spindle device 3 from colliding with the PCB board 5, thereby increasing the stability of the device of the present application. The first drive assembly 21 is arranged at the lower end of the side wall of the spindle device 3. The first drive assembly 21 can be a cylinder, a motor screw or other structures.

[0026] In one embodiment, the ejector pin 22 is spaced apart from the spindle device 3. In this embodiment, the axis of the ejector pin 22 is parallel to the axis of the spindle device 3, so that the movement direction of the ejector pin 22 and the movement direction of the spindle device 3 can be ensured to be consistent, and the movement trajectory of the ejector pin 22 can be easily controlled. When one of the ejector pins 22 and the spindle device 3 is located in the processing position, the spacing arrangement of the ejector pin 22 and the spindle device 3 can facilitate the other of the two to be located in the avoidance position.

[0027] In one embodiment, the ejector pin has an extended state and a retracted state, and the first driving component 21 can drive the ejector pin 22 to switch between the extended state and the retracted state. When the ejector pin 22 is in the extended state, the outer end of the ejector pin 22 extends to the outside of the end of the spindle device 3 close to the processing table 4, and when the ejector pin 22 is in the retracted state, the outer end of the ejector pin 22 retracts to the inside of the end of the spindle device 3 close to the processing table 4. In this embodiment, when the first driving component 21 is a cylinder, the cylinder body of the cylinder is arranged on the spindle device 3, the axis of the piston rod of the cylinder is parallel to the axis of the spindle device 3, the ejector pin 22 is arranged at the outer end of the piston rod of the cylinder, and the axis of the ejector pin coincides with the axis of the piston rod. When the positioning part withdrawal process is performed, the piston rod of the cylinder is extended, and the ejector pin 22 is in an extended state, so that the outer end of the ejector pin 22 extends to a distance outside the lower end surface of the spindle device 3 (the end close to the processing table 4) in the Z direction, so that when the ejector pin 22 pushes the positioning pin 51, the spindle device 3 is still located above the PCB board 5, which can prevent the spindle device 3 from colliding with the PCB board 5; when processing is performed, the piston rod of the cylinder is retracted, and the ejector pin 22 is in a retracted state, so that the outer end of the ejector pin 22 is retracted in the Z direction to a distance inside the lower end surface of the spindle device 3, so that when the spindle device 3 processes the PCB board 5, the ejector pin 22 is located above the PCB board 5, which can prevent the ejector pin 22 from hitting the PCB board 5.

[0028] In one embodiment, the PCB processing equipment further includes a conveying device 6, which is located at one end of the processing table 4, and the conveying device 6 is at least used to convey the PCB board 5 along the processing table 4. In this embodiment, along the first direction, the conveying device 6 can be located at any end of the processing table 4, and the conveying device 6 conveys the PCB board 5 along the first direction. The rubber tapping device 1 is movably connected to the processing table 4 along the second direction. The first direction is not parallel to the second direction and does not overlap. The first direction is the conveying direction of the conveying device 6. The processing table 4 has a processing station, a positioning member withdrawal station and a rubber tapping station. During processing, the conveying device 6 conveys the PCB board 5 to the processing station, and when the positioning member is withdrawn, the conveying device 6 conveys the PCB board 5 to the positioning member withdrawal station. When tapping, the conveying device 6 conveys the PCB board 5 to the rubber tapping station, wherein the processing station, the positioning member withdrawal station and the rubber tapping station are independent of each other, and may overlap or not overlap. The conveying device 6 can be located at any end of the processing table 4, wherein one mode is that, along the first direction, the rubber tapping station is behind the positioner withdrawal station, and after the PCB board 5 is subjected to the positioner withdrawal process, the conveying device 6 conveys the PCB board 5 to the rubber tapping station for the rubber tapping process. The conveying device 6 includes a motor, a driving wheel, a driven wheel and a conveyor belt, and the conveyor belt is looped on the driving wheel and the driven wheel, and the driving wheel, the conveyor belt and the driven wheel are driven by the rotation of the motor to realize the transportation of the PCB board 5. In other embodiments, along the first direction, the rubber tapping device 1 can be arranged on the processing table 4, and can also be arranged on the side of the processing table 4.

[0029] In one embodiment, the processing station and the rubber tapping station are sequentially arranged along the first direction, and the conveying device 6 is located on the side of the processing station away from the rubber tapping station, or the conveying device 6 is located on the side of the rubber tapping station away from the processing station. Taking the conveying device 6 located on the side of the processing station away from the rubber tapping station as an example, the PCB board 5 to be processed is placed on the conveying device 6, the conveying device 6 is started, the PCB board 5 is transported to the processing station, the spindle device 3 moves to the processing station, and the PCB board 5 is processed according to the preset processing parameters. After the processing is completed, the spindle device 3 moves to a safe position; the processed PCB board 5 is moved from the processing station to the rubber tapping station through the conveying device 6. During the movement, it is ensured that the PCB board is stable and will not be damaged. The rubber tapping device 1 is started, and the PCB board 5 is tapped according to the preset rubber tapping parameters. After the rubber tapping is completed, the rubber tapping device 1 stops working and moves to a safe position, and the PCB board 5 that has been tapped is taken out from the rubber tapping station for subsequent processing (such as cleaning, testing, etc.). At the same time, the conveying device 6 continues to convey the new PCB board 5 to the processing station to prepare for the next round of processing. If the conveying device 6 is located on the side of the rubber tapping station away from the processing station, the order of the work process will be adjusted accordingly, but the overall process remains clear and orderly. By optimizing the process, improving space utilization, enhancing flexibility and improving production efficiency, it brings significant economic benefits and competitive advantages to PCB processing.

[0030] In one embodiment, the conveying device 6 is located on the side of the rubber tapping station away from the processing station, and the conveying device is used to convey the PCB board 5 to the processing station and to recover the PCB board 5 on the processing station; The tapping device 6 has a tapping state and a non-tapping state. When the conveying device 6 conveys the PCB board 5 to the processing station, the tapping device 6 is in the non-tapping state, and the PCB board 5 moves to the processing station after passing through the tapping station. When the conveying device 6 recovers the PCB board 5 on the processing table, the tapping device 1 is in the tapping state, and the PCB board 5 passes through the tapping station and moves to the conveying device 6 after completing the tapping. In this embodiment, the PCB5 board is first conveyed to the processing table by the conveying device 6, and the PCB board 5 moves through the tapping station, but at this time the tapping device 1 is in the non-tapping state, and the PCB board 5 does not perform tapping. The PCB board 5 continues to move to the processing station for processing. After the processing is completed, the PCB board 5 passes through the tapping station again, and at this time the tapping device 1 is in the tapping state, and the PCB board 5 completes tapping. The PCB board 5 that has completed tapping is recovered by the conveying device 6. The PCB board 5 completes processing and tapping in the process of passing through the processing table once, reducing additional handling and processing steps, and by reasonably setting the states of the conveying device 6 and the tapping device 1, it is ensured that the PCB board 5 performs the correct operation at the correct station. In another embodiment, the PCB board 5 is transported to the processing table 4 through the conveying device 6, and the PCB board 5 is directly moved to the processing station for processing. After the processing is completed, the PCB board 5 is moved to the rubber tapping station for rubber tapping. The PCB board 5 after rubber tapping reaches the unloading position and is unloaded by manual or other mechanisms (such as AGV). By integrating the rubber tapping device 1, the need for additional rubber tapping equipment is reduced, the rubber tapping process is accurately controlled, the damage caused by handling is reduced, the quality of the PCB board is improved, and the production cost and space requirements are reduced.

[0031] In one embodiment, the PCB processing equipment has at least two tapping devices 1, at least two tapping devices 1 are arranged at intervals, and the conveying device 6 is located between the at least two tapping devices 1. In this embodiment, there is no tape on the front and rear sides (the opposite sides in the first direction) of the PCB board 5, and the tape on the PCB board 5 is located on the upper and lower sides and the left and right sides of the PCB board 5. In this embodiment, the tape cutting process is completed by cutting the tape on the left and right sides (the opposite sides in the second direction) of the PCB board 5. Each tapping device 1 of the present application corresponds to a tapping position. When performing the tapping process, the two tapping devices 1 are respectively moved to the corresponding tapping positions, so that the two tapping devices 1 cut the tape on both sides of the PCB board 5 at the same time. By cutting the tape at multiple positions, it is convenient to tear off the tape that has been cut. The conveying device 6 conveys the PCB board 5 along the first direction, and at least two rubber tapping devices 1 are arranged at intervals along the second direction. The first direction is perpendicular to the second direction, so that the moving direction of the two rubber tapping devices 1 can be perpendicular to the conveying direction of the conveying device 6. When the two rubber tapping devices 1 move to two rubber tapping positions to cut the tape on the two opposite sides of the PCB board 5, the force of the PCB board 5 can be balanced to avoid deflection. In other embodiments, the PCB processing equipment also includes a fixing device for fixing the PCB board 5, and the position of the PCB board 5 is fixed by the fixing device during the processing process, the positioning member withdrawal process and the rubber tapping process.

[0032] In one embodiment, the rubber tapping device 1 is disposed on a table top of a processing table 4; The rubber tapping device 1 is movably connected to the processing table 4 along the second direction; Or, the tapping device 1 is fixed on the processing table 4. In this embodiment, when the tapping device 1 is movably connected to the processing table 4 along the second direction, the tapping device 1 can reciprocate between the tapping position and the non-tapping position. When the tapping device 1 is located at the tapping position, the tape on the PCB board 5 of the tapping station can be cut, and the first direction is perpendicular to the second direction. When the tapping device 1 is fixed on the processing table 4, the tapping device 1 is a laser generator, and the cutting of the tape is completed by laser. The integrated design of the tapping device 1 allows the operator to complete multiple processes at the same station, simplifies the operation process, reduces the complexity of operation, and the integrated tapping device 1 reduces the demand for additional equipment, thereby reducing the overall equipment investment cost. The tapping device 1 is movably connected to the processing table 4 along the second direction, and can reciprocate between the tapping position and the non-tapping position. This design makes the tapping process more flexible, reduces the transfer time of the PCB board 5 between different stations, and thus improves the overall production efficiency. In the PCB processing equipment, the table top of the processing table 4 refers to a side surface of the processing table 4 for placing and fixing the PCB board 5 .

[0033] In one embodiment, the tapping device 1 is arranged on the side wall of the processing table 4; the tapping device 1 can move relative to the processing table 4 along the second direction; and / or, the tapping device 1 can move relative to the processing table 4 along the third direction, and the third direction is perpendicular to the second direction. In this embodiment, the tapping device 1 can move in the third direction (up and down direction) and in the second direction (left and right direction), and the tapping device 1 is movably connected to the side wall of the processing table 4 along the second direction, so that the tapping device 1 can switch between the tapping position and the non-tapping position, and when the tapping device 1 is located at the tapping position, it can cut the tape on the PCB board 5 of the tapping station, and the tapping device 1 can be raised and lowered along the up and down direction (third direction), and the up and down direction, the first direction and the second direction are perpendicular to each other. The mobile design of the tapping device 1 allows it to move out of the working area of ​​the PCB board 5 when tapping is not required, so that the use space of the processing table 4 can be maximized, and it can be quickly in place when tapping is required, thereby improving the flexibility and adaptability of the production line. The reciprocating movement and lifting function of the rubber tapping device 1 make the rubber tapping process more precise, and can be adjusted for PCB boards 5 of different thicknesses and materials to ensure the quality of rubber tapping. Among them, the side wall refers to the part of the two sides of the processing table 4 that is perpendicular to the table surface, and the rubber tapping device 1 is located at the rear side of the processing table 4 along the first direction. The lifting and lowering of the rubber tapping device 1 can be achieved by structures such as a cylinder and a motor screw. In another embodiment, the rubber tapping device 1 cannot be lifted and lowered, and can only move along the second direction, that is, the rubber tapping device 1 is fixed in a position that cannot be lifted and lowered, and it can only move along the second direction of the processing table. This design simplifies the structure of the rubber tapping device 1, making it more stable and easy to maintain. In another embodiment, the rubber tapping device 1 cannot move along the second direction, and can only be lifted and lowered (moved along the third direction), that is, the rubber tapping device 1 is designed to be able to move vertically (lift) but not horizontally. This design allows the rubber tapping device 1 to tap PCB boards 5 of different thicknesses, which increases the flexibility of processing to a certain extent.

[0034] In one embodiment, the rubber tapping device 1 includes a rubber tapping head 11, a connecting member and a second driving assembly.
