Description

Technical Field

[0001] The invention relates to the technical field of punchers, and in particular to a disc puncher with a self-cleaning function. Background Art

[0002] Radio Frequency Identification (RFID) is a type of automatic identification technology that uses wireless radio frequency to perform non-contact two-way data communication and read and write recording media (such as electronic tags or radio frequency cards) to achieve the purpose of identifying targets and exchanging data.

[0003] In the production process of card carriers such as electronic tags or radio frequency cards, in order to facilitate the printing of cards or to meet specific card design requirements, it is sometimes necessary to punch holes in the cards. At present, the common punching equipment is mainly a multi-station disc punching machine. When punching holes, the drill will produce a lot of debris when drilling the card. If the debris is not cleaned up in time, it will not only affect the punching accuracy of the card, but also may cause damage to the card.

[0004] At present, the common debris cleaning method is mainly manual cleaning, which has low cleaning efficiency and cannot guarantee the cleaning effect. Based on this, Chinese invention patent CN202311130947.X discloses a punching machine with a debris cleaning and collection device, including a displacement control unit, a drill unit, a debris collection unit, and a mounting table. The displacement control unit is fastened to the upper and lower plates of the mounting table, the drill unit is installed on the displacement control unit, and the debris collection unit is connected to the drill unit and the mounting plate. The displacement control unit controls the movement of the drill unit in three dimensions, and the debris collection unit avoids the splashing of punching debris through airflow guidance, reducing the possibility of the surface of the PCB board being scratched by debris. Specifically, the debris collection unit includes a collection hood, a receiving box, and an air pump vacuum cleaner. An air inlet and an air outlet are arranged on the collection hood, and the air outlet is connected to the air pump vacuum cleaner through a pipe. When the punching machine starts drilling, the bottom of the collection hood is attached to the surface of the PCB board, and the air pump vacuum cleaner draws air outward from the air outlet. There is airflow from the outside into the collection hood at the air inlet, and the debris splashed during drilling is discharged from the air outlet into the air pump vacuum cleaner under the guidance of the airflow.

[0005] It can be found that the technical solution provided by the above patent document is mainly to suck the debris to the outside through an air pump vacuum cleaner. Although this method can collect and clean most of the debris, the cleaning effect is poor for those debris that are stubbornly attached to the surface of the drill bit. In particular, when it is necessary to drill certain materials that are easy to adhere to the surface of the drill bit (such as polyvinyl chloride, etc.), it is impossible to achieve the peeling between the drill bit surface and the debris by only using the air extraction method, which is not conducive to improving the debris cleaning effect, and further affects the accuracy and yield rate of product production.

[0006] This shows that the prior art needs to be further improved and enhanced. Summary of the invention

DETAILED DESCRIPTION

[0022] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0023] Reference Figure 1-Figure 4 As shown, an embodiment of the present invention provides a disc punch with a self-cleaning function, including a body 100, a dust collection assembly 200 and a chip removal assembly 300; the body 100 includes a base 110 and a drilling mechanism 120 arranged on the base 110; a turntable 111 is arranged on the base 110, the drilling mechanism 120 has a rotary arm 121 and a drill bit 122 arranged at the end of the rotary arm 121, and the rotary arm 121 has a processing position for driving the drill bit 122 to be suspended above the turntable 111, and a standby position for driving the drill bit 122 to be suspended outside the turntable 111; the dust collection assembly 200 includes a dust collection pipe 210 and a dust collection box 220 connected to the dust collection pipe 210, and the air inlet (not marked in the figure) of the dust collection pipe 210 is arranged close to the drill bit 122; the chip removal assembly 300 is arranged on the base 110, and is provided with a chip removal groove 311 matching the drill bit 122. Among them, in the processing position, the debris generated by the drill bit 122 drilling can be sucked into the dust box 220 by the dust suction pipe 210; in the standby position, the rotary arm 121 can drive the drill bit 122 into the chip removal groove 311 to remove the debris on the surface of the drill bit 122.

[0024] It should be noted that the disc punching machine is a common punching device, and its working process is mainly: placing the product to be processed on the turntable 111. Since the turntable 111 is usually connected to the driving mechanism, the turntable 111 can rotate relative to the base 110 under the drive of the driving mechanism, so that the product to be processed can move with the movement of the turntable 111; and when the product to be processed rotates to the bottom of the drilling mechanism 120, the drill bit 122 moves to the processing position under the drive of the rotary arm 121, so that the drill bit 122 performs a punching operation on the product to be processed. It can be understood that to realize the above working process, the disc punching machine will inevitably be provided with related structures such as a driving mechanism, a transmission mechanism, a control mechanism, and a workpiece fixing mechanism, and the specific setting methods, types, and setting positions of these structures can all refer to the relevant descriptions in the prior art. Since the correlation between this part of the content and the core invention point of this application is weak, this part of the content will not be elaborated on here. In addition, the turntable 111 of the disc punching machine is usually provided with a plurality of processing stations so as to be able to process a plurality of products respectively. For example, the turntable 111 may have ten stations, or twelve stations, etc., which is not limited in the present application.

[0025] In addition, since the drill bit 122 is disposed at the end of the rotary arm 121 and can move with the movement of the rotary arm 121. Therefore, regarding the movement process of the rotary arm 121, not only is it necessary for the rotary arm 121 to rotate relative to the base 110 so that the drill bit 122 can switch between the processing position and the standby position, but it is also necessary for the rotary arm 121 to move up and down relative to the base 110 so that the drill bit 122 can move up and down and contact the product to be processed at the processing position. In order to realize the above movement process, the drilling mechanism 120 can have a variety of different implementations, and the present application does not limit the specific structure of the drilling mechanism 120. For example, in one embodiment, the rotary arm 121 may include a first linear module, a second linear module, and a rotating seat, the first linear module is rotatably connected to the base 110, the second linear module cooperates with the first linear module, so that the second linear module can move up and down along the extension direction of the first linear module; the rotating seat cooperates with the second linear module so that it can move horizontally along the extension direction of the second linear module; and the drill bit 122 cooperates with the rotating seat to realize the self-rotation of the drill bit 122. In another embodiment, the rotary arm 121 may include a first support arm and a second support arm connected vertically, the first support arm is rotatably connected to the base 110, the second support arm is slidably connected to the first support arm, and a rotating seat is fixed to the end of the second support arm, and the drill bit 122 cooperates with the rotating seat.

[0026] It should also be noted that, since the products to be processed may have a variety of different processing requirements, that is, the diameters and types of holes to be punched on the products to be processed may be different. Therefore, the specifications and types of the drill bit 122 may also be various, such as twist drill, flat drill, step drill, tapered drill, spiral groove drill, etc. Moreover, in order to ensure that the chip groove 311 can match different drill bits 122, the shape and size of the chip groove 311 may also have a variety of different implementations, such as strip-shaped grooves, arc grooves, step grooves, spiral grooves, etc., which are not limited in this application.

[0027] The disc punch with self-cleaning function provided by the present invention, on the one hand, collects the debris generated in the equipment processing process through the suction force generated by the dust suction tube 210, thereby being able to avoid the debris from affecting the product processing process to a certain extent, and is beneficial to improving the processing accuracy of the equipment; on the other hand, the drill bit 122 can enter the chip groove 311 in the standby position, and through the cooperation between the chip groove 311 and the drill bit 122, the debris attached to the surface of the drill bit 122 is removed, thereby further helping to improve the cleaning effect of the equipment for the debris, and can help to further improve the processing accuracy of the equipment, and can greatly improve the product yield.

[0028] In some embodiments, continue to refer to Figure 4 As shown, the base 110 is provided with a connection hole (not shown in the figure), the chip removal assembly 300 includes a chip removal plate 310 and a connection member 320, a chip removal groove 311 is formed through the surface of the chip removal plate 310, and the connection member 320 cooperates with the connection hole to achieve the connection between the chip removal plate 310 and the base 110. The chip removal groove 311 can be a strip groove, the connection member 320 can be a bolt, a screw, a pin, etc., and the connection hole can be a threaded hole that cooperates with the bolt, the screw, etc., or a light hole that cooperates with the pin.

[0029] Through the cooperation between the connecting member 320 and the connecting hole, the chip removing plate 310 and the base 110 can be detachably connected, so that the staff can easily replace and repair the chip removing assembly 300. In addition, in this connection mode, since the connecting member 320 passes through the chip removing groove 311 to fix the chip removing plate 310, the size of the chip removing groove 311 can be adjusted, which is conducive to improving the adaptability between the chip removing groove 311 and the drill bit 122 to a certain extent.

[0030] In other embodiments, reference Figure 5 As shown, the chip removing assembly 300 includes a first clamping body 330 and a second clamping body 340, a first half groove (not marked in the figure) is formed on the side of the first clamping body 330, the second clamping body 340 is adapted to the first clamping body 330, and a second half groove (not marked in the figure) is formed on the side of the second clamping body 340, and the first half groove and the second half groove are enclosed to form a chip removing groove 311.

[0031] It is understandable that the chip groove 311 can be a fixed groove or a variable groove in addition to the above-mentioned fixed groove. By setting the first clamping body 330 and the second clamping body 340, the chip groove 311 formed by the first half groove and the second half groove can be adjusted, so as to achieve the adaptation between the chip groove 311 and different drill bits 122, thereby facilitating the chip removal effect of the chip groove 311 on the drill bit 122.

[0032] Regarding the connection and fixing method between the first clamping body 330, the second clamping body 340 and the base 110, the present application can have a variety of different implementations:

[0033] Implementation method 1: Continue to refer to Figure 5 As shown, the first clamping body 330 is provided with a first fixing hole (not marked in the figure), the second clamping body 340 is provided with a second fixing hole (not marked in the figure), and the base 110 is provided with positioning holes (not shown in the figure) corresponding to the first fixing hole and the second fixing hole respectively; the chip removal assembly 300 also includes a fastener 350, which passes through the first fixing hole, the second fixing hole and the positioning hole respectively to achieve a detachable connection between the first clamping body 330, the second clamping body 340 and the base 110. Optionally, the outer surface of the fastener 350 may be provided with threads, and the first fixing hole, the second fixing hole and the positioning hole may all be threaded holes.

[0034] This arrangement, through the detachable connection between the first clamping body 330, the second clamping body 340 and the base 110, is not only convenient for the staff to adjust the chip groove 311 formed by the first clamping body 330 and the second clamping body 340, but also convenient for the staff to perform maintenance, replacement and other operations on the first clamping body 330 and the second clamping body 340.

[0035] Embodiment 2: The first clamping body 330 and the second clamping body 340 are rotatably connected to the base 110 respectively, so that the size of the chip removal groove 311 can be adjusted. Specifically, one end of the first clamping body 330 and one end of the second clamping body 340 are rotatably connected to the base 110 respectively, and the other end of the first clamping body 330 and the other end of the second clamping body 340 are fixedly connected to the base 110 respectively, so that after the chip removal groove 311 is adjusted in place, the first clamping body 330 and the second clamping body 340 are fixed relative to the base 110, thereby facilitating the stability of the chip removal process of the chip removal assembly 300.

[0036] In some embodiments, reference Figure 1 and Figure 3As shown, the turntable 111 has a plurality of punching positions (not marked in the figure) distributed along its circumference; the air inlet of the dust suction pipe 210 is provided with a guide cover 211, and the guide cover 211 forms a guide area, which can cover the drill bit 122 and the punching positions. The punching position is a kind of processing station, and the product to be processed is fixed on the turntable 111 by punching holes on the turntable 111.

[0037] Through the setting of the guide cover 211, it is possible to collect not only the debris on the surface of the drill bit 122, but also the scattered debris during the operation of the drill bit 122, and the debris dropped inside the drilling position, which is beneficial to improving the equipment's effect of collecting debris, and the guiding area formed by the guide cover 211 can be arc-shaped or trapezoidal to improve the guiding effect for the debris.

[0038] In some embodiments, reference Figure 4 As shown, a plurality of dust collecting holes (not shown in the figure) are provided on the surface of the turntable 111 corresponding to the plurality of punching positions; a cleaning disc 112 is coaxially arranged above the turntable 111, and a plurality of cleaning brushes 113 corresponding to the plurality of punching positions are extended from the cleaning disc 112 along the radial direction of the turntable 111, and the cleaning brushes 113 can clean the debris on the plurality of punching positions into the plurality of dust collecting holes.

[0039] The diameter of the cleaning disc 112 may be smaller than the diameter of the rotating disc 111, and the cleaning disc 112 may be fixedly connected to the base 110, so that the rotating disc 111 can rotate relative to the cleaning disc 112, so that during the movement of the rotating disc 111, the contact between the cleaning brush 113 and the rotating disc 111 can be used to clean the debris in the punching positions on the rotating disc 111. It is understandable that the number of cleaning brushes 113 may correspond to the number of punching positions one by one, or the number of cleaning brushes 113 may be less than the number of punching positions, and the present application does not limit the number of cleaning brushes 113.

[0040] Optionally, the dust collecting hole may also be connected to a collection pipe (not shown in the figure), and the collection pipe is connected to the dust collecting box 220 in the dust collecting assembly 200 to collect the debris in the punching position.

[0041] In some embodiments, continue to refer to Figure 4 As shown, the base 110 has a feeding position (not marked in the figure) formed on the outside of the turntable 111, and the body 100 also includes a grabbing assembly 130 arranged above the turntable 111, and the grabbing assembly 130 can cooperate with the workpiece to realize the switching of the workpiece between the feeding position and the punching position.

[0042] Further, refer to Figure 1As shown, the machine body 100 further includes a feed channel 140 and a feed rack 141. The feed channel 140 is formed inside the base 110. The feed rack 141 is arranged on the base 110 corresponding to the feed channel 140 and is provided with a feed port connected to the feed channel 140. The feed rack 141 is at the same height as the turntable 111 so that the feed position is flush with the punching position. The position of the feed rack 141 on the base 110 forms the feed position.

[0043] In addition, refer to Figure 4 As shown, the grabbing assembly 130 includes a slide rail 131, a fixing seat 132 and a suction cup 133. The slide rail 131 is arranged on the base 110 along the radial direction of the turntable 111. The fixing seat 132 cooperates with the slide rail 131 and can move along the extension direction of the slide rail 131. The suction cup 133 is arranged on the fixing seat 132 and has a suction state that can suck the workpiece at the feed port, and has a separation state that releases the workpiece to the punching position. Through the arrangement of the above grabbing assembly 130, automatic feeding of the equipment can be realized, which is conducive to improving product processing efficiency.

[0044] It is understandable that, regarding the specific structure of the grabbing assembly 130, in addition to the above-mentioned sliding suction cup 133 structure, a moving claw structure may also be adopted, and the present application does not make any specific limitation on this.

[0045] In the description provided herein, a large number of specific details are described.
