[0002] In the electronics manufacturing industry, components are usually provided with pin structures for binding connections. However, during the production and processing of the pins, due to the existence of errors, the lengths of the pins are easily uneven, so the pins need to be cut.

[0025] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.
[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an automatic pin cutting machine 10 includes: a feeding conveying device 100, a cutting device 200, a feeding conveying device 300 and a component transplanting device 400, wherein the feeding conveying device 100 is provided with a feeding end; the cutting device 200 includes a cutting module 210 and a pressing and positioning module 220, wherein the pressing and positioning module 220 is provided on one side of the cutting module 210, and the pressing and positioning module 220 is used to press and position the component, and the cutting module 210 is used to press and position the pins on the component 20 The cutting operation is performed; the unloading conveying device 300 is provided with a unloading end, and the cutting device 200 is located between the loading conveying device 100 and the unloading conveying device 300; the component transplanting device 400 includes a transplanting module 410 and a clamping module 420, the transplanting module 410 is connected to the clamping module 420, the clamping module 420 is used to clamp and fix the component 20, and the transplanting module 410 is used to drive the clamping module 420 to reciprocate between the loading end, the cutting module 210 and the unloading end.
[0027] It should be noted that when it is necessary to cut the pins of the components 20, the components 20 are first loaded by the loading and conveying device 100, so that the components 20 are moved to the loading end; then the components 20 are clamped and fixed by the clamping module 420 above the loading end. After the clamping and fixing are completed, the components 20 on the clamping module 420 are moved to the cutting module 210 of the cutting device 200 by the transplanting module 410, and then the cutting module 210 is pressed and positioned by the pressing and positioning module 220. 0 is pressed and positioned to ensure that the bottom surface of the component 20 is tightly fitted with the cutting module 210, so as to avoid the position movement of the component 20 during the cutting process, thereby ensuring the consistency of the cutting size, and further improving the accuracy and consistency of the cutting; after the cutting operation is completed, the component 20 that has completed the cutting operation is transferred to the unloading conveying device 300 through the transfer module 410 and the clamping module 420, and the component 20 is unloaded uniformly through the unloading conveying device 300. In this way, the automatic cutting operation of the component 20 can be realized, thereby replacing the manual cutting operation or the semi-automatic cutting operation, reducing manual intervention, improving production efficiency, and ensuring the accuracy and consistency of the cutting size.
[0028] See also Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the loading and conveying device 100 includes a loading and conveying limit frame 110, a conveying limit belt 120 and a conveying drive module 130. The loading and conveying limit frame 110 is provided with a conveying limit groove 111. The conveying limit belt 120 is arranged in the conveying limit groove 111. The component 20 is placed in the conveying limit groove 111, and the conveying limit belt 120 is supported on the bottom of the component 20. The conveying drive module 130 is connected to the conveying limit belt 120. The conveying drive module 130 is used to drive the conveying limit belt 120 to rotate so that the component 20 moves along the conveying limit groove 111 to the loading end.
[0029] It should be noted that, by providing a conveying limit groove 111 on the feeding conveying limit frame 110, the conveying limit groove 111 can be used to limit the two sides of the component 20 to avoid position deviation of the component 20; in addition, since pins are provided at the bottom of the component 20, if the component 20 is directly placed in the conveying limit groove 111, and the pins of the component 20 are in direct contact with the conveying limit groove 111, the component 20 cannot be placed stably, and problems such as position deviation or skewed collapse may occur, resulting in the subsequent clamping module 420 being unable to perform normal clamping operations on the component 20, and it is also possible to Pins are squeezed and damaged, so in this embodiment, by setting a conveying limit belt 120 on the conveying limit groove 111, the conveying limit belt 120 is carried on the bottom of the component 20, so that the pins of the component 20 are suspended relative to the bottom of the conveying limit groove 111, then the pins of the component 20 will not directly contact the bottom of the conveying limit groove 111, so as to ensure the stability and accuracy of the placement of the component 20; at the same time, the conveying limit belt 120 is driven to move by the conveying drive module 130, so that the component 20 on the conveying limit belt 120 can move along the conveying limit groove 111 to the loading end. In this way, not only can the smooth conveying of the component 20 be achieved and the position accuracy of the component 20 be ensured, but also the problem of squeeze damage caused by the pins of the component 20 contacting the conveying limit groove 111 can be avoided.
[0030] Furthermore, a plurality of conveyor limiting belts 120 are provided, each conveyor limiting belt 120 is arranged at intervals, and each conveyor limiting belt 120 is carried on the bottom of the component 20. The number of conveyor limiting belts 120 can be selected for matching according to the size specifications of the component 20. In this embodiment, the number of conveyor limiting belts 120 is three, and the conveyor limiting belts 120 are arranged at intervals. When carrying the component 20, the pins of the component 20 are in a suspended state.
[0031] See also Figure 2 and Figure 3As shown, further, the conveying limit groove 111 is also provided with a limit groove 111a, and the conveying limit belt 120 is accommodated in the limit groove 111a, and the limit groove 111a is used to limit the conveying limit belt 120. In this way, the conveying limit belt 120 can avoid problems such as position deviation or shaking in the process of carrying and conveying the components 20, thereby improving the stability of the conveying of the components 20 and the accuracy of the position. In this embodiment, the conveying limit groove 111 is also provided with a pin avoidance groove 111b, and the pin avoidance groove 111b is located on one side of the limit groove 111a, that is, the pin avoidance groove 111b is located on one side of the conveying limit belt 120. When the conveying limit belt 120 carries the components 20, the pins on the components 20 are located in the pin avoidance groove 111b, so that the pins are suspended, ensuring that the pins will not be scratched or squeezed.
[0032] See also Figure 2 As shown, in one embodiment, the conveying drive module 130 includes a driving motor structure 131, a main transmission roller 132, a plurality of auxiliary rollers 133, a head end roller 134 and a tail end roller 135, the head end roller 134 and the tail end roller 135 are respectively rotatably arranged on the feeding conveying limit frame 110, and the head end roller 134 and the tail end roller 135 are located in the conveying limit groove 111, the main transmission roller 132 and each auxiliary roller 133 are respectively arranged below the conveying limit groove 111, and the conveying limit belt 120 passes through the head end roller 134, each auxiliary roller 133, the main transmission roller 132 and the tail end roller 135 respectively to form a closed loop; the driving motor structure 131 is connected to the main transmission roller 132, and the driving motor structure 131 is used to drive the main transmission roller 132 to rotate, so that the conveying limit belt 120 drives the components 20 to move along the conveying limit groove 111.
[0033] It should be noted that there are two auxiliary rollers 133, which are located on both sides of the main transmission roller 132, and cooperate with the head end roller 134 and the tail end roller 135 to ensure the tension of the conveying limit belt 120. When the driving motor structure 131 is started, it will drive the main transmission roller 132 to rotate, so that the conveying limit belt 120 can be rotated, and then cooperate with the auxiliary rollers 133, the head end roller 134 and the tail end roller 135 to realize the movement of the conveying limit belt 120, thereby driving the movement of the components 20. In this embodiment, the main transmission roller 132, each auxiliary roller 133, the head end roller 134 and the tail end roller 135 are all provided with positioning grooves, and the conveying limit belt 120 is accommodated in the positioning grooves, so that the conveying limit belt 120 can be prevented from being offset. In this embodiment, the conveying limit belt 120 can be made of rubber material, and the conveying limit belt 120 is circular in structure.
[0034] In one embodiment, in order to improve the degree of automation and ensure the accuracy of the stop position of the component 20, an optical fiber sensor 140 is provided on the loading and conveying limit frame 110. For example, the optical fiber sensor 140 is provided on the loading end or other positions where the stop control is required. When the optical sensor recognizes that the component 20 is placed on the loading end, other components are controlled to start action or the loading and conveying device 100 is controlled to stop.
[0035] In one embodiment, the structure of the loading conveying limiting frame 110 is the same as the structure of the unloading conveying limiting frame.
[0036] Due to the existence of factors such as shaking during the process of the loading and conveying device 100 conveying the components 20, the clamping module 420 on the component transfer device 400 cannot ensure the accuracy of the position from the loading end to the cutting device 200 when clamping and conveying the components 20. If the components 20 are offset, the component transfer device 400 will not be able to smoothly place the components 20 into the cutting positioning area on the cutting device 200. Therefore, before the cutting device 200 is used, the position of the components 20 needs to be further positioned and adjusted. Please refer to Figure 1 and Figure 5 As shown, the automatic foot cutting machine 10 further includes a positioning adjustment device 500, which is located between the feeding and conveying device 100 and the cutting device 200, and is used to adjust the position of the component 20. In this way, the position accuracy of the component transfer device 400 transferring the component 20 to the cutting module 210 can be ensured.
[0037] Specifically, the positioning adjustment device 500 includes a positioning support platform 510, a positioning adjustment member 520 and a positioning adjustment driving member 530. The top surface of the positioning support platform 510 is provided with an avoidance through hole, and the positioning support platform 510 is provided with a driving member installation cavity, the avoidance through hole is communicated with the driving member installation cavity, the positioning adjustment member 520 is located on the avoidance through hole, the positioning adjustment driving member 530 is located in the driving member installation cavity, and the positioning adjustment driving member 530 is connected to the positioning adjustment member 520, and the positioning adjustment driving member 530 is used to drive the positioning adjustment member 520 to adjust the position of the component 20. In this embodiment, the positioning adjustment member 520 includes a plurality of positioning blocks 521, each of which is surrounded by a positioning area, the component 20 is located on the positioning area, and each of the positioning blocks 521 is respectively connected to the positioning adjustment driving member 530, and the positioning adjustment driving member 530 is used to drive each of the positioning blocks 521 to move in a direction close to or away from the component 20. In this embodiment, the positioning adjustment drive member 530 is a four-claw cylinder, and correspondingly, four positioning blocks 521 are provided, and the four positioning blocks 521 are respectively connected to the four driving ends of the four-claw cylinder. The use of the four-claw cylinder is conducive to the synchronization of the movement of each positioning block 521, thereby ensuring the uniformity of the clamping force of the positioning block 521 on each clamping part of the component 20. In this embodiment, in order to prevent the positioning block 521 from causing scratches or clamping injuries to the component 20 when clamping the component 20, the positioning block 521 uses a buffer rubber block.
[0038] See also Figure 4 As shown, in one embodiment, the cutting module 210 includes a cutting positioning table 211 and a cutting piece 212, the cutting portion of the cutting piece 212 is located below the cutting positioning table 211, when the component 20 is placed on the cutting positioning table 211, the pins on the component 20 pass through the cutting positioning table 211 and are partially located on the back of the cutting positioning table 211, the pressing and positioning module 220 is used to press and position the component 20 so that the component 20 is tightly fitted with the cutting positioning table 211, and the cutting piece 212 is used to cut the pins on the component 20.
[0039] It should be noted that a cutting positioning cavity 211a is provided on the cutting positioning platform 211, and a pin positioning hole 211b is provided on the cutting positioning cavity 211a. The component 20 is placed on the cutting positioning cavity 211a, and the pins of the component 20 are respectively accommodated in the pin positioning holes 211b, and are partially located on the back of the cutting positioning platform 211. Then, the component 20 can be pressed and positioned by the pressing and positioning module 220, so that the component 20 and the cutting positioning platform 211 are closely fitted to avoid the position movement of the component 20 during the cutting process, thereby ensuring the consistency of the cutting size. Then, the pins on the component 20 are cut by the cutting piece 212. Specifically, the cutting piece 212 includes a cutting knife and a cutting drive cylinder. The cutting knife is connected to the cutting drive cylinder, and the cutting knife is driven by the cutting drive cylinder to realize the cutting operation of the pins of the component 20. In this embodiment, the cutting module 210 also includes a waste collection box 213, which is located below the cutting positioning table 211. The waste cut by the cutting piece 212 will fall directly onto the waste collection box 213, thereby facilitating the centralized collection of waste and preventing waste from polluting the production environment.
[0040] It should also be noted that, in one embodiment, the cutting and positioning platform 211 includes a cutting base and a component positioning block, the cutting base is provided with a mounting cavity, and the component positioning block is detachably mounted on the cutting base. In this way, the component positioning block can be replaced according to components 20 of different specifications, so that the automatic pin cutting machine 10 can cut the pins of components 20 of various specifications, thereby improving the versatility of the automatic pin cutting machine 10.
[0041] See also Figure 4 As shown, in one embodiment, when the pins of the component 20 are cut, the applied cutting force will cause the component 20 to move, resulting in a large deviation in the cutting size, so it is necessary to set a pressing and positioning module 220 to press and position the component 20. Specifically, the pressing and positioning module 220 includes a pressing and mounting block 221, a pressing and positioning rod 222, a pushing rod 223, and a pressing and driving member 224. The pressing and mounting block 221 is installed on one side of the cutting module 210, and the pressing and positioning rod 222 is hinged to one end of the pressing and mounting block 221 and the pushing rod 223 respectively. The other end of the pushing rod 223 is connected to the pressing and driving member 224. The pressing and driving member 224 is used to drive the pushing rod 223 to achieve linear displacement, so that the pushing rod 223 pushes the pressing and positioning rod 222 to press and position the component 20 on the cutting module 210. In this embodiment, the pressing driving member 224 may be a cylinder. When the driving end of the cylinder is extended, the pushing rod 223 pushes the pressing positioning rod 222 to press the top surface of the component 20 , thereby realizing the pressing and positioning operation of the component 20 .
[0042] See also Figure 4 As shown, in one embodiment, the pressing and positioning rod 222 includes a pressing and positioning portion, a first hinge portion, and a second hinge portion connected in sequence, the pressing and positioning portion is used to press the components 20 on the cutting module 210, the first hinge portion is hinged to the pressing and mounting block 221, and the second hinge portion is hinged to one end of the pushing rod 223. When the pushing rod 223 pushes the pressing and positioning rod 222, the first hinge portion rotates relative to the pressing and mounting block 221, and the second hinge portion rotates relative to the pushing rod 223.
[0043] In one embodiment, a buffer rubber block is provided on one side of the pressing and positioning portion facing the cutting module 210, and the pressing and positioning portion is used to contact and abut the top surface of the component 20 when the component 20 on the cutting module 210 is pressed. In this way, the surface of the component 20 can be prevented from being crushed by the buffer rubber block.
[0044] See also Figure 6 As shown, in one embodiment, the transplanting module 410 includes a supporting base 411, a lifting plate 412, a transverse moving plate 413 and a transplanting drive 414, the supporting base 411 is provided with a lifting rail, the lifting plate 412 is slidably set on the lifting rail, the lifting plate 412 is provided with a transverse rail, and the transverse moving plate 413 is slidably set on the transverse rail; the clamping module 420 is installed on the transverse moving plate 413; the transplanting drive 414 is connected to the transverse moving plate 413, and the transplanting drive 414 is used to drive the transverse moving plate 413 to realize reciprocating transverse displacement along the transverse slide rail, and is also used to drive the lifting plate 412 to realize reciprocating lifting and lowering displacement along the lifting rail.
[0045] It should be noted that when the clamping module 420 clamps the component 20 from the loading end, the transfer drive 414 is started, and the lifting plate 412 and the transverse moving plate 413 are simultaneously actuated. At this time, the lifting plate 412 rises, and the transverse moving plate 413 moves toward the direction close to the cutting device 200, thereby transferring the component 20 to the next station. Specifically, the transfer drive 414 includes a servo motor 414a and a rotating block 414b. The servo motor 414a is installed on a side surface of the support base 411 away from the lifting plate 412, and the driving end of the servo motor 414a passes through the support base 411 and is connected to one end of the rotating block 414b, and the other end of the rotating block 414b is connected to the transverse moving plate 413 through a connecting shaft. When the servo motor 414a is started, the driving end of the servo motor 414a drives the rotating block 414b to rotate with the driving end of the servo motor 414a as the rotating point, so that the lifting plate 412 moves up and down along the lifting rail, and the lateral moving plate 413 moves horizontally along the lateral rail, so that the clamping module 420 can be driven to perform a transplant operation on the component 20. In this way, through the transplanting module 410, the linkage of each transplanting action can be ensured, thereby improving the transplanting efficiency, and reducing the use of driving parts, thereby making the overall structure more compact.
[0046] In order to avoid the problem of the component 20 being squeezed and damaged when the clamp 421 takes and places the component 20, please refer to Figure 6 and Figure 7 As shown, in one embodiment, the clamping module 420 includes a clamping jaw 421 and an anti-pressure component 422 . The anti-pressure component 422 is disposed on the transplanting module 410 , and the clamping jaw 421 is disposed on the anti-pressure component 422 .
[0047] It should be noted that, when the clamping jaws 421 usually clamp components 20 and place the components 20 on each workstation, the machine itself has certain errors. When the machine error is within the controllable range, there will still be errors in the position of the components 20. When the machine error and the position error of the components 20 exist, it will cause the clamping jaws 421 to clamp the components 20 and place them on the transplanting module 410. It is impossible to ensure that the pins on the components 20 can be completely aligned with the pin positioning holes 211b. At this time, if the transplanting module 410 drives the clamping jaws 421 to directly insert the pins on the components 20 into the pin limiting holes, it may cause the pins of the components 20 to be bent or damaged, thereby reducing the yield rate of the components 20. Therefore, by adding the anti-pressure component 422, it can play a role in buffering and anti-pressure when the clamping jaws 421 take and place the components 20.
[0048] Specifically, the anti-pressure component 422 includes an anti-pressure moving plate 422a, a buffer spring rod 422b and a sensor 422c. A first mounting block is provided on the transplanting module 410, and one end of the buffer spring rod 422b is provided on the first mounting block; a second mounting block is provided on the anti-pressure moving plate 422a, and the other end of the buffer spring rod 422b is provided on the second mounting block; an anti-pressure guide rail 415 is also provided on the transplanting module 410, and an anti-pressure guide block is provided on a side surface of the anti-pressure moving plate 422a facing the anti-pressure guide rail 415, and the anti-pressure guide block is slidably connected to the anti-pressure guide rail 415; the sensor 422c is provided on a side surface of the transplanting module 410, and an induction sheet 422d is provided on the anti-pressure moving plate 422a.
