Description

Technical Field

[0001] The present application relates to the field of terminal processing, and in particular to a positioning and correction device for a pin insertion machine. Background Art

[0002] Reference Figure 1 When the terminal 4 is produced, a stamping method is often used to stamp the terminal 4 on the material strip 41, and then the material strip 41 after the terminal 4 is formed is wound on a winding machine.

[0003] Reference Figure 1 The pins 42 are usually inserted and installed on the terminals 4 using a pin insertion machine. The pin insertion machine usually includes a processing table and a vibration plate. The processing table is equipped with a transmission mechanism for transferring the material strip 41 from the winder to the processing station. The vibration plate is used to store the pins 42 and discharge the pins 42 in an orderly manner. The discharge end of the vibration plate is provided with a needle loading mechanism for lifting the pins 42 to the processing station of the processing table and then inserting the pins 42 into the terminals 4 on the processing station. The processing table is also provided with a bending mechanism for bending the terminals 4 to clamp the pins 42 in the terminals 4.

[0004] Reference Figure 1 The terminal 4 includes a carrier sheet 411 integrally formed on the material strip 41, and clamping sheets 412 are integrally formed on both sides of the carrier sheet 411 in the length direction. The pin 42 is inserted between the clamping sheet 412 and the carrier sheet 411. The clamping sheet 412 is used to clamp the pin 42 and press it against the carrier sheet 411. The bending mechanism is used to bend the clamping sheet 412 and press it tightly against the pin 42.

[0005] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: after the material strip 41 is wound on the winder and then transferred to the processing station of the processing table, when the material strip 41 and the terminal 4 are hit by external force, it is easy to cause the carrier sheet 411 connected to the material strip 41 to warp up. At this time, when the terminal 4 is on the processing station, the gap between the carrier sheet 411 and the clamping sheet 412 will be difficult to align with the corresponding pin 42, thereby producing defective products and affecting the yield rate. Summary of the Invention

[0006] In order to improve the problem that the terminal is easily warped on the material strip, which makes it difficult to align the terminal with the pin, the present application provides a positioning and correction device for a pin insertion machine.

[0007] The present application provides a positioning and correction device for a pin insertion machine, which adopts the following technical solutions:

[0008] A positioning and correction device for a pin insertion machine includes a processing table, a winding machine for winding a material strip is provided on the processing table, a needle loading mechanism for discharging the pins to a processing station on the processing table is also provided on the processing table, a transmission mechanism for transmitting the material strip to the processing station is also provided on the processing table, a positioning mechanism is provided on the processing table, the positioning mechanism is used to position the material strip on the processing station in the transmission direction, and a correction mechanism is provided on the positioning mechanism, the correction mechanism is used to press the upturned carrier sheet to be aligned with the insertion pin of the needle loading mechanism.

[0009] By adopting the above technical solution, the terminal is positioned in the transmission direction of the material strip by the positioning mechanism, and the angle between the carrier sheet and the material strip is corrected by the correction mechanism, thereby ensuring that the terminal and the pin are aligned, making it easier for the needle-loading mechanism to insert the pin into the terminal, greatly improving the yield rate of the pin and terminal insertion processing, and reducing the probability of bending or skewing of the terminal or material strip due to external force during transmission or transportation, which makes it difficult for the subsequent pin to be inserted into the terminal, thereby producing defective products.

[0010] Optionally, the positioning mechanism includes a positioning seat that is raised and lowered on the processing table, and the positioning seat is provided with a plurality of positioning grooves for placing terminals, and a positioning block slides in the positioning groove, and the positioning block is used to slide and push the terminal until it contacts the inner wall of the positioning groove, and the positioning seat is provided with a positioning drive member for driving the positioning block to slide.

[0011] By adopting the above technical solution, the positioning seat is pressed down to cover the terminal in the positioning groove, and the positioning block is slid to push the terminal to abut against the inner wall of the positioning groove, thereby realizing the positioning of the terminal, reducing the probability that the terminal is not transferred to the designated processing station during transmission, resulting in difficulty in inserting the pin into the terminal, facilitating the subsequent operation of correcting the terminal angle, and controlling the sliding of the positioning block by the positioning drive member, realizing automation, reducing the workload of the staff, and improving processing efficiency.

[0012] Optionally, a protection block is provided on the inner wall of the positioning groove, the width of the protection block is the same as the width of the terminal, and the protection block is used to abut against the positioning block to limit the positioning block and push the terminal.

[0013] By adopting the above technical solution, when the positioning block pushes the terminal to contact the inner wall of the positioning groove to complete the positioning, the positioning block now contacts the protective block. If the positioning drive component fails and continues to operate, the protective block will prevent the positioning block from continuing to push the terminal by contact, thereby reducing the positioning block from continuing to push the terminal, making the probability of the terminal being clamped between the positioning block and the inner wall of the positioning groove and being deformed by the extrusion force, thereby protecting the terminal.

[0014] Optionally, the correction mechanism includes a correction block rotating on the inner wall of the positioning groove, the correction block abuts against the carrier plate, and the correction block is used to rotate the upward-curved carrier plate to align with the insertion needle on the upper needle mechanism. The positioning seat is provided with a correction drive component for controlling the rotation of the correction block.

[0015] By adopting the above technical solution, when the positioning of the terminal is completed, the correction block can be rotated so that the correction block passes through between adjacent clamping pieces and abuts against the side wall of the carrier piece. By continuing to rotate the correction block to abut against the carrier piece, the carrier piece is rotated on the material strip, thereby correcting the bending angle between the carrier piece and the material strip, realizing the resetting of the positional relationship between the terminal and the material strip, thereby greatly improving the yield rate of the insertion processing between the pin and the terminal.

[0016] Optionally, an auxiliary block is provided on the correction block, and the auxiliary block is used to abut against the side wall of the clamping piece. When the correction block rotates, the correction block and the auxiliary block abut against each other to rotate the terminal to a suitable angle.

[0017] By adopting the above technical solution, the correction block contacts the carrier sheet, and the auxiliary block contacts the clamping sheet, thereby dispersing part of the pressure on the carrier sheet to the clamping sheet, reducing the probability of deformation of the carrier sheet due to excessive pressure. At the same time, since the positional relationship between the correction block and the auxiliary block is fixed, the correction block and the auxiliary block contact each other to simultaneously drive the carrier sheet and the clamping sheet to rotate, reducing the pressure on the carrier sheet from being excessively dispersed to the clamping sheet, causing the clamping sheet to bend, thereby reducing the space between the clamping sheet and the carrier sheet, resulting in the probability of difficulty in inserting subsequent pins, and protecting both the carrier sheet and the clamping sheet.

[0018] Optionally, a pressure dividing plate is rotatably provided on the side wall of the correction block, and the pressure dividing plate is used to contact the carrier sheet together with the correction block, and a pressure dividing control component for controlling the rotation of the pressure dividing plate is provided on the correction block.

[0019] By adopting the above technical solution, the pressure dividing plate is in contact with the carrier sheet, so that the side wall of the pressure dividing plate and the side wall of the correction block are in contact with the carrier sheet together, thereby increasing the force-bearing area of the carrier sheet, reducing the pressure per unit area of the carrier sheet, and further reducing the probability of the carrier sheet being deformed due to force; at the same time, since the pressure dividing plate was originally retracted on the correction block, when the correction block passes through the clamping sheet, the pressure dividing plate is opened again and contacts the carrier sheet, which fully utilizes the width of the carrier sheet that is greater than the distance between adjacent clamping sheets, and also reduces the probability of the pressure dividing plate being stuck by the clamping sheet.

[0020] Optionally, a slide groove is provided on the correction block, and the pressure dividing control component includes a trigger block sliding in the slide groove, and the trigger block is used to interfere with the supporting plate to achieve extension and contraction in the slide groove. The trigger block is provided with a tooth groove on the side wall, and a gear meshing with the tooth groove is provided on the rotating shaft of the pressure dividing plate. The trigger block slides in the slide groove through the tooth groove and the gear to drive the pressure dividing plate to rotate.

[0021] By adopting the above technical solution, when the correction block contacts the carrier plate, the trigger block is squeezed and slides into the slide groove, and then the pressure divider plate is rotated out through the engagement of the tooth groove and the gear. The automatic triggering and rotation of the pressure divider plate is realized through the mechanical structure. The structure is reliable and durable, with a long service life, which reduces the workload of the staff, realizes automation, and improves processing efficiency.

[0022] Optionally, a spring is provided between the bottom wall of the chute and the trigger block, and the spring expands and contracts along the direction in which the trigger block slides out of the chute.

[0023] By adopting the above technical solution, when the correction block completes the correction of the terminal angle, the correction block is reset through the correction drive component. At this time, the conflict between the trigger block and the carrier plate is released, so that the trigger block pops out toward the outside of the slide groove under the action of the elastic force of the spring, and the pressure dividing plate is rotated back to the correction block through the cooperation of the tooth groove and the gear, so that the correction block can slide out smoothly from between the adjacent clamping plates, reducing the influence of the pressure dividing plate on the rotation of the correction block.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The angle between the carrier sheet and the material strip is corrected by the correction mechanism, which ensures the alignment of the terminal and the pin, greatly improving the yield rate of the pin and terminal insertion processing, and reducing the probability of the terminal or material strip being bent or skewed due to external force during transmission or transportation, which makes it difficult for the subsequent pin to be inserted into the terminal, thereby producing defective products.

[0026] 2. It reduces the workload of subsequent staff in screening out defective products and improves processing efficiency.

[0027] 3. The contact area between the correction block and the terminal is increased by the voltage divider plate and the auxiliary block, which plays a protective role on the carrier piece and the clamping piece. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] The embodiment of the present application discloses a positioning correction device for a pin insertion machine. Figure 1 and Figure 2 The positioning and correction device for the pin insertion machine includes a processing table 1. Winders 11 for winding up the material strip 41 are installed at both ends of the processing table 1 in the length direction. One winder 11 is used to wind up the material strip 41 and the terminal 4 to be processed, and the other winder 11 is used to wind up the terminal 4 and the material strip 41 after the pin 42 is installed. The winder 11 only plays the role of winding up the material strip 41, and does not have the function of transmitting and conveying the material strip 41. The two winders 11 are distributed along the length direction of the processing table 1, so that the material strip 41 is transmitted along the length direction of the processing table 1.

[0038] Reference Figure 2 and Figure 3A transmission mechanism 13 for transmitting the material belt 41 to the processing station is installed on the processing table 1. In this embodiment, the transmission mechanism 13 adopts a transmission wheel 131. A transmission hinge ear is fixedly connected to the processing table 1, and the transmission hinge ear is rotatably connected to the transmission wheel 131. The transmission wheel 131 is located above the transmission path of the material belt 41 on the processing table 1. A plurality of transmission blocks 132 are fixedly connected to the outer peripheral wall of the transmission wheel 131, and the plurality of transmission blocks 132 are evenly distributed on the transmission wheel 131 in the circumferential direction. The material belt 41 is provided with a plurality of transmission grooves 133 for inserting transmission blocks 132. When the transmission wheel 131 rotates, the transmission blocks 132 rotate into the transmission grooves 133. As the transmission wheel 131 rotates, the transmission blocks 132 will abut against the inner wall of the transmission grooves 133, thereby pushing the material belt 41 forward. When the transmission block 132 rotates out of the transmission groove 133, the next transmission block 132 will rotate into the next transmission groove 133 to continue transmission.

[0039] Reference Figure 1 and Figure 2 and Figure 4 , also includes a vibration plate for storing and orderly discharging pins 42. A needle loading mechanism 12 is also mounted on the processing table 1. The feed end of the needle loading mechanism 12 corresponds to the discharge end of the vibration plate. After the pins 42 enter the needle loading mechanism 12, the needle loading mechanism 12 lifts the pins 42 onto the processing table 1 and then pushes and inserts the pins 42 between the carrier sheet 411 and the clamping sheet 412. A positioning mechanism 2 is also mounted on the processing table 1. The positioning mechanism 2 is used to position the material strip 41 at the processing station in the transmission direction. The positioning mechanism 2 is mounted on the correction mechanism 3. The correction mechanism 3 is used to press the upturned carrier sheet 411 until it is aligned with the pins 42 of the needle loading mechanism 12.

[0040] Reference Figure 2 and Figure 4 The positioning mechanism 2 includes a lifting cylinder 211 fixedly connected to the processing table 1. A positioning seat 21 is fixedly connected to the telescopic rod of the lifting cylinder 211. The positioning seat 21 is located above the transmission path of the material strip 41, and the telescopic rod of the lifting cylinder 211 is extended and retracted in the direction closer to or away from the transmission path of the material strip 41. The side wall of the positioning seat 21 facing the transmission path of the material strip 41 is provided with a plurality of positioning grooves 22 for placing the terminals 4. The plurality of positioning grooves 22 are evenly distributed along the transmission path of the material strip 41, and the cross-sectional width of the positioning grooves 22 is less than the distance between adjacent terminals 4 on the material strip 41. When the side wall of the positioning seat 21 is pressed against the material strip 41, the positioning grooves 22 cover the terminals 4 on the material strip 41, and each positioning groove 22 contains only one terminal 4.

[0041] Reference Figure 2 and Figure 4 and Figure 5A clearance groove 212 is also provided on the side wall of the positioning seat 21 facing the material strip 41 for making way for the material strip 41. When the positioning groove 22 covers the terminal 4 and the side wall of the positioning seat 21 around the positioning groove 22 contacts the processing table 1, the inner wall of the clearance groove 212 contacts the material strip 41.

[0042] Reference Figure 5 A positioning rod 231 is provided on the positioning seat 21, and the positioning rod 231 passes through a plurality of positioning grooves 22. A plurality of positioning blocks 23 are fixedly connected to the positioning rod 231. The positioning blocks 23 slide in the positioning grooves 22, and the plurality of positioning blocks 23 correspond to the plurality of positioning grooves 22 one by one, and the side walls of the positioning blocks 23 are in contact with the inner walls of the positioning grooves 22, and the positioning rod 231 slides along the transmission path of the material belt 41.

[0043] Reference Figure 5 The positioning block 23 is used to slide and push the terminal 4 until it contacts the inner wall of the positioning groove 22. A positioning drive member 24 is installed on the positioning seat 21 to drive the positioning block 23 to slide. The positioning drive member 24 includes a positioning motor 241 fixedly connected to the outer wall of the positioning seat 21. A positioning screw 242 is fixedly connected to the rotating shaft of the positioning motor 241. The length direction of the rotating shaft of the positioning motor 241 is the same as the length direction of the positioning screw 242, so that the positioning screw 242 and the rotating shaft of the positioning motor 241 rotate coaxially. The positioning screw 242 is inserted into the positioning rod 231 and threadedly connected. The insertion direction of the positioning screw 242 is the same as the sliding direction of the positioning rod 231. Since the positioning block 23 contacts the inner wall of the positioning groove 22, the rotation of the positioning rod 231 is limited, so that the sliding of the positioning rod 231 is controlled by the rotation of the positioning screw 242.

[0044] Reference Figure 5 , several protective blocks 25 are fixedly connected to the inner walls of the positioning grooves 22. The width of the protective blocks 25 is the same as the width of the terminal 4. The protective blocks 25 are fixedly connected to the side walls of the positioning grooves 22 that are in contact with the terminal 4 processing station. The protective blocks 25 are used to contact the positioning blocks 23 to limit the positioning blocks 23 from pushing the terminal 4. When the positioning blocks 23 push the terminal 4 to the processing station, the positioning blocks 23 will contact the protective blocks 25, making it difficult for the positioning blocks 23 to continue sliding, resulting in the terminal 4 being squeezed and compressed.

[0045] Reference Figure 1 and Figure 5 and Figure 6 The correction mechanism 3 includes a number of correction blocks 31 rotating on the inner wall of the positioning groove 22. The correction block 31 abuts against the carrier plate 411. The rotation axis of the correction block 31 passes through the positioning seat 21, and the rotation axis of the correction block 31 passes through a number of positioning grooves 22. The correction block 31 corresponds to the positioning groove 22 one by one, and the correction block 31 corresponds to the processing station of the terminal 4 in the positioning groove 22.

[0046] Reference Figure 1 and Figure 2 and Figure 5 The correction block 31 is used to rotate and press the upward-warped carrier sheet 411 until it is aligned with the pin 42 on the upper needle mechanism 12. A correction drive member 32 for controlling the rotation of the correction block 31 is installed on the positioning seat 21. The correction drive member 32 includes a correction motor 321 fixedly connected to the positioning seat 21. The correction motor 321 and the positioning motor 241 are respectively fixed on the two side walls of the positioning seat 21 facing away from each other, and the rotation axis of the correction motor 321 is fixedly connected to the rotation axis of the correction block 31. The length direction of the rotation axis of the correction motor 321 is the same as the length direction of the rotation axis of the correction block 31, so that the rotation axis of the correction motor 321 and the rotation axis of the correction block 31 rotate coaxially.

[0047] Reference Figure 1 and Figure 6 The width of the correction block 31 is smaller than the distance between the clamping pieces 412 on both sides of the carrier piece 411. The correction block 31 is inserted into the gap between adjacent clamping pieces 412 and then abuts against the side wall of the carrier piece 411. At this time, the end of the correction block 31 away from the carrier piece 411 is outside the clamping piece 412. Two auxiliary blocks 33 are fixedly connected to the end of the correction block 31 away from the carrier piece 411. The two auxiliary blocks 33 are respectively fixed to the side walls of the correction block 31 on both sides. The side walls of the auxiliary blocks 33 facing the clamping piece 412 are used to abut against the side walls of the clamping piece 412 facing away from the carrier piece 411. When the correction block 31 rotates, the correction block 31 abuts against the side walls of the carrier piece 411, and the auxiliary blocks 33 abut against the clamping piece 412, so that the correction block 31 and the auxiliary blocks 33 abut together to rotate the terminal 4 to the appropriate angle.

[0048] Reference Figure 1 and Figure 5 and Figure 7 A slot 351 is defined on the side wall of the correction block 31 facing the carrier plate 411. A pressure control member 35 is mounted on the correction block 31. The pressure control member 35 includes a trigger block 352 that slides within the slot 351. The side wall of the trigger block 352 abuts against the inner wall of the slot 351, allowing the trigger block 352 to slide in and out of the slot 351. A spring 36 is fixedly connected between the bottom wall of the slot 351 and the side wall of the trigger block 352 facing away from the opening of the slot 351. The spring 36 extends and contracts in the direction of the slide 351 sliding out of the slot 351.

[0049] Reference Figure 6 and Figure 7A pressure-dividing groove 341 is defined on the side wall of the correction block 31, located between the side wall where the chute 351 is located and the side wall where the pressure-dividing plate 34 is located. There are two pressure-dividing grooves 341, symmetrically distributed on the opposite side walls of the correction block 31. A pressure-dividing plate 34 is rotatably connected within the pressure-dividing groove 341. When the pressure-dividing plate 34 is rotated outward, the side wall of the pressure-dividing plate 34 contacts the side wall of the carrier 411. The rotating shaft of the pressure-dividing plate 34 passes through the opposite side walls of the pressure-dividing groove 341 within the correction block 31. A gear 354 is fixedly connected to the rotating shaft of the pressure-dividing plate 34. The teeth of the gear 354 extend through the inner wall of the pressure-dividing groove 341 and into the chute 351, allowing the gear 354 to rotate within the correction block 31.

[0050] Reference Figure 1 and Figure 6 and Figure 7 A plurality of tooth grooves 353 are provided on the side walls of both sides of the trigger block 352. The tooth grooves 353 are divided into two groups. The tooth grooves 353 in the same group are evenly distributed along the sliding direction of the trigger block 352, and the tooth grooves 353 in the two groups are respectively engaged with two gears 354. As the supporting plate 411 contacts the trigger block 352, the trigger block 352 slides into the slide groove 351, and the gear 354 is driven to rotate through the engagement of the tooth grooves 353 and the gear 354, so that the pressure dividing plate 34 rotates out of contact with the supporting plate 411 to achieve the purpose of increasing the contact area.

[0051] The implementation principle of the positioning and correction device for a pin insertion machine in the embodiment of the present application is as follows: when the pin 42 and the terminal 4 are to be inserted and processed, the material strip 41 is first pulled onto the processing table 1 by the transmission mechanism 13, and then the positioning seat 21 is pressed down so that the terminal 4 is in the positioning groove 22, and then the terminal 4 is positioned against the inner wall of the positioning groove 22 by sliding the positioning block 23, and then the positioning seat 21 is completely pressed down so that the side wall of the positioning seat 21 around the positioning groove 22 is pressed onto the processing table 1, and at the same time, the inner wall of the give way groove 212 is pressed against the material strip 41; and then the correction block 31 is rotated so that the correction block 31 enters from the gap between the adjacent clamping pieces 412, and the trigger block 352 is pressed against the side wall of the carrier piece 411, As the correction block 31 continues to rotate, the trigger block 352 slides deeper into the slide groove 351. At this time, the tooth groove 353 drives the gear 354 to rotate, so that the pressure divider 34 rotates out. Finally, the side walls of the pressure divider 34, the side walls of the trigger block 352 and the side walls of the correction block 31 around the opening surface of the slide groove 351 jointly abut against the side walls of the carrier sheet 411. At the same time, the auxiliary block 33 abuts against the side walls of the clamping sheet 412. The correction block 31 continues to rotate to drive the carrier sheet 411 to rotate on the material belt 41 until the position of the carrier sheet 411 is corrected and rotated so that the space between the clamping sheet 412 and the carrier sheet 411 is aligned with the pin 42 in the discharging state on the upper needle mechanism 12. At this time, the correction of the position of the terminal 4 is completed.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
