[0032] Reference Figures 1 to 3 According to an embodiment of the present invention, the pin calibration device includes a loading platform 100, a second driving component 200, a third driving component 300, a calibration component 400 and a rack 500. The loading platform 100 is used to place components with pins 810 (such as relays 800 and diodes, etc., and the relays 800 are used as an example in the following description) so that the calibration unit 420 can calibrate the pins 810. The second driving component 200 is used to drive the calibration component 400 to approach or move away from the loading platform 100 so as to calibrate the pins 810. After completing the calibration of the pins 810, the calibration component 400 is separated from the pins 810 to prepare for the next pin calibration. The third driving component 300 is used to drive the calibration component 400 to move along the switching direction (i.e., the front-to-back direction) so that after the calibration component 400 completes the calibration of the pins 810 on the front side, it continues to calibrate the pins 810 on the rear side. The calibration component 400 is the main mechanism for completing the calibration action.

[0033] Reference Figure 2 and Figure 3In some embodiments of the invention, the loading platform 100 includes a photoelectric sensor assembly 110, a support seat 120 and an insert block 130. The lower end of the support seat 120 is fixed to the frame 500 by screw locking, and the upper end surface of the support seat 120 is a loading surface 121, and the loading surface 121 is used to place the relay 800. The insert block 130 is protrudingly provided on the loading surface 121, and the relay 800 is provided with a first through hole 830, and the insert block 130 is inserted into the first through hole 830. Therefore, the insert block 130 can limit the relay 800, and the relay 800 will not move forward, backward, left and right along the loading surface 121.

[0034] Reference Figure 2 and Figure 3 In a further embodiment of the invention, the cross section of the insert block 130 is rectangular, and the first through hole 830 is a rectangular hole. After the insert block 130 is inserted into the first through hole 830, the relay 800 can only move in the up-down direction, and the relay 800 will neither move forward, backward, leftward, nor rightward on the loading surface 121, nor rotate around the axis in the up-down direction. When the pin 810 of the relay 800 is calibrated, the relay 800 will not move randomly, thereby ensuring that the pin 810 can be effectively calibrated.

[0035] Reference Figure 2 In some specific embodiments of the invention, the photoelectric sensor assembly 110 includes a mounting plate 111 and a photoelectric sensor 112. A positioning hole is provided in the mounting plate 111, and the photoelectric sensor 112 is inserted into the positioning hole. Therefore, when the relay 800 is inserted into the plug block 130, the time for the light emitted by the photoelectric sensor 112 to be reflected back changes, thereby determining whether the plug block 130 is inserted with the relay 800, thereby preventing the calibration assembly 400 from operating when it is unloaded.

[0036] Specifically, the photoelectric sensor 112 may be a reflective photoelectric sensor or a through-beam photoelectric sensor.

[0037] Reference Figure 2 In some specific embodiments of the invention, the second driving assembly 200 includes a second oil pressure buffer 210, a second sliding assembly 220, a second mounting plate 230 and a second cylinder 240. The cylinder body of the second cylinder 240 is locked and fixed to the frame 500, and the telescopic rod of the second cylinder 240 is locked and fixed to the second mounting plate 230 by a fastener. The second sliding assembly 220 includes a second slider 221 and a second slide rail 222, the second slide rail 222 and the second slider 221 are slidably connected, the length direction of the second slide rail 222 is arranged along the left and right direction, the second slide rail 222 is locked and fixed to the frame 500 by screws, and the second slider 221 is locked and fixed to the second mounting plate 230 by screws. The second sliding assembly 220 is provided with two groups, and is arranged in parallel along the front-back direction.

[0038] Therefore, when the second air cylinder 240 is connected to the air source and operates, the second mounting plate 230 is driven to slide in the left-right direction.

[0039] Two second oil pressure buffers 210 are provided, and the two second oil pressure buffers 210 are respectively fixed at the left end and the right end of the frame 500 . The second oil pressure buffers 210 are used to limit the second mounting plate 230 and buffer the impact of the second mounting plate 230 .

[0040] In other embodiments, the second driving assembly 200 may also be replaced by a combination of a motor, a lead screw, and a nut.

[0041] Reference Figure 2 In some specific embodiments of the invention, the third driving assembly 300 includes a third oil pressure buffer 310, a third sliding assembly 320, a third cylinder 330, a third mounting plate 340 and a stopper 350. The cylinder body of the third cylinder 330 is locked and fixed to the second mounting plate 230, and the telescopic rod of the third cylinder 330 is locked and fixed to the third mounting plate 340 by a fastener. The third sliding assembly 320 includes a third slide rail 321 and a third slider 322, the third slide rail 321 and the third slider 322 are slidably connected, the length direction of the third slide rail 321 is set along the front-back direction, the third slide rail 321 is locked and fixed to the second mounting plate 230 by screws, and the third slider 322 is locked and fixed to the third mounting plate 340 by screws. The third driving assembly 300 is provided with two groups, and is arranged in parallel along the left-right direction.

[0042] Therefore, after the third air cylinder 330 is connected to the air source and starts working, it will drive the third mounting plate 340 to move along the switching direction (ie, the front-rear direction).

[0043] Two third oil pressure buffers 310 are provided, and the two third oil pressure buffers 310 are fixed to the right end of the second mounting plate 230 and are arranged at intervals in the front-to-back direction. A stopper 350 is fixed to the right end of the third mounting plate 340 by screw locking, and the stopper 350 is located between the two third oil pressure buffers 310, thereby buffering and limiting the third mounting plate 340.

[0044] Similarly, the third driving assembly 300 may also be replaced by a combination of a motor, a lead screw and a nut.

[0045] Reference Figure 4 , Figure 5 and Figure 7In some specific embodiments of the invention, the calibration component 400 is fixed to the third mounting plate 340. Under the action of the second driving component 200, the calibration component 400 will move in the left-right direction. Under the action of the third driving component 300, the calibration component 400 will move in the front-back direction. The calibration component 400 includes a mounting seat 410 and a calibration unit 420. The calibration unit 420 includes a calibration component assembly 421, a limit assembly 422, a first clamping block 423, a second clamping block 424, a first driving component 425 and a positioning component 426. Under the cooperation of the second driving component 200, the calibration component assembly 421 calibrates the pin 810 to bend upward or downward. Under the drive of the first driving component 425, the first clamping block 423 and the second clamping block 424 calibrate the pin 810 to bend leftward or rightward. The limit assembly 422 is used to limit the relay 800 to prevent the relay 800 from moving upward, thereby preventing the relay 800 from detaching from the plug 130. The positioning assembly 426 is used to determine the minimum distance between the first clamping block 423 and the second clamping block 424 .

[0046] Reference Figure 5 and Figure 6 In some specific embodiments of the invention, the mounting base 410 is fixed to the third mounting plate 340 by screws, and the mounting base 410 includes a bottom plate 411, a support block 412 and a top plate 413, the top plate 413 is located above the bottom plate 411, and the two ends of the support block 412 are respectively locked and fixed to the top plate 413 and the bottom plate 411, and a plurality of support blocks 412 are provided.

[0047] Reference Figure 5 and Figure 6 In some specific embodiments of the invention, the calibration component assembly 421 includes a clamp block 611 and a calibration component 612. The clamp block 611 is fixed to the left end of the top plate 413 by screws. A slot is provided in the clamp block 611. The calibration component 612 is embedded in the slot and fixed by screws. The position of the clamp block 611 can be adjusted up and down. Therefore, under the action of the second driving assembly 200, the calibration component 612 will follow the third mounting plate 340 to move left or right, and then approach or move away from the object loading platform 100.

[0048] Reference Figure 5 and Figure 6 In some specific embodiments of the invention, a calibration port 614 is opened on the left side of the calibration member 612, and the calibration port 614 includes a first calibration surface 613 and a second calibration surface 615. Along the direction in which the pin 810 is inserted into the calibration port 614 (i.e., the rightward direction), the distance between the first calibration surface 613 and the second calibration surface 615 gradually decreases. Therefore, when the pin 810 bent upward or downward enters the calibration port 614, it will be constrained and deformed by the first calibration surface 613 or the second calibration surface 615 and will no longer bend upward or downward.

[0049] Reference Figures 3 to 5 In some specific embodiments of the invention, the limit assembly 422 includes a first pressure block 621 and a second pressure block 622, and the first pressure block 621 and the second pressure block 622 are both fixed to the left end of the top plate 413 by screws, and the lower end of the first pressure block 621 is located in front of the lower end of the second pressure block 622. The first pressure block 621 and the second pressure block 622 are both used to limit the upward movement of the relay 800 along the plug block 130. Specifically, the first pressure block 621 or the second pressure block 622 is limited by abutting against the step surface 820 at the upper end of the relay 800. In addition, when the pin 810 on the front side of the relay 800 is calibrated, the relay 800 is limited by the second pressure block 622. When the pin 810 on the rear side of the relay 800 needs to be calibrated, the top plate 413 will move backwards. At this time, the relay 800 is limited by the first pressure block 621.

[0050] It should be noted that when the pin 810 is inserted into the calibration port 614, the first pressure block 621 (or the second pressure block 622) and the loading surface 121 clamp the relay 800, and when the pin 810 is separated from the calibration port 614, the first pressure block 621 (or the second pressure block 622) releases the relay 800 so that the relay 800 can be removed from the insertion block 130.

[0051] Reference Figure 7 and Figure 8 In some embodiments of the invention, the first clamping block 423 is provided with a first shaping surface 661, and the second clamping block 424 is provided with a second shaping surface (with reference to the first clamping block 423, the second clamping block 424 and the first clamping block 423 are symmetrical in shape). Under the action of the first driving assembly 425, the first shaping surface 661 and the second shaping surface can be attached to the pin 810 located in the calibration port 614, or separated from the pin 810 located in the calibration port 614.

[0052] Reference Figure 5 , Figure 7 and Figure 8 In some specific embodiments of the invention, the first driving assembly 425 includes a first clamping arm 631, a first roller 632, a second slide 633, a first slide 634, a first driving element 635, a push plate 636, a second roller 637, a second clamping arm 638, a first rotating shaft 639 and an elastic member. A second through hole is formed at the left end of the first clamping arm 631, a third through hole is formed at the left end of the second clamping arm 638, the first rotating shaft 639 passes through the second through hole and the third through hole, and is respectively matched with the second through hole and the third through hole in clearance, and the two ends of the first rotating shaft 639 are respectively fixed to the top plate 413 and the bottom plate 411. Thus, the first clamping arm 631 and the second clamping arm 638 are both rotatably connected to the mounting seat 410.

[0053] The first clamp block 423 is fixed to the left end of the first clamp arm 631 by screws and is located at the front side of the first clamp arm 631. The second clamp block 424 is fixed to the left end of the second clamp arm 638 by screws and is located at the rear side of the second clamp arm 638. The first clamp block 423 and the second clamp block 424 are arranged opposite to each other. When the first clamp arm 631 and the second clamp arm 638 are clamped or opened, the first clamp block 423 and the second clamp block 424 can be brought together or separated.

[0054] The first roller 632 is rotatably connected to one end (i.e., the right end) of the first clamping arm 631 away from the first clamping block 423, and the second roller 637 is rotatably connected to one end (i.e., the right end) of the second clamping arm 638 away from the second clamping block 424. The upper surface of the bottom plate 411 is provided with a first slide groove 711 and a second slide groove 712 in parallel, and the length direction of the first slide groove 711 and the second slide groove 712 is arranged along the left-right direction. The lower end of the first slide plate 634 is inserted into the first slide groove 711, and the lower end of the second slide plate 633 is inserted into the second slide groove 712. Thus, the first slide plate 634 can slide in the left-right direction relative to the mounting seat 410, and the second slide plate 633 can slide in the left-right direction relative to the mounting seat 410.

[0055] The first slide plate 634 is provided with a first guide surface on its rear side, the second slide plate 633 is provided with a second guide surface 642 on its front side, the first roller 632 is in contact with the first guide surface, and the second roller 637 is in contact with the second guide surface 642. The right end of the first slide plate 634 and the right end of the second slide plate 633 are both fixedly connected to the push plate 636, and the output end of the first driving element 635 is connected to the push plate 636. Therefore, when the first driving element 635 drives the first slide plate 634 and the second slide plate 633 to move to the left, the first clamping arm 631 and the second clamping arm 638 are clamped.

[0056] The first driving element 635 can be a pneumatic cylinder or a hydraulic cylinder.

[0057] In order to enable the first clamp arm 631 and the second clamp arm 638 to open after being clamped, an elastic member is provided. Specifically, the elastic member is a compression spring. A sleeve 641 is fixed to the first clamp arm 631, and the compression spring is inserted in the sleeve 641. A baffle 643 is fixed to the second clamp arm 638 by screws, and the baffle 643 abuts against the compression spring. When the first clamp arm 631 and the second clamp arm 638 are clamped, the compression spring is compressed. When the first slide plate 634 and the second slide plate 633 move to the right, the compression spring recovers its deformation, and the first clamp arm 631 and the second clamp arm 638 are stretched open.

[0058] In addition, the elastic member may also be a torsion spring, one pin of the torsion spring abuts against the first clamping arm 631 , and the other pin of the torsion spring abuts against the second clamping arm 638 .

[0059] In another embodiment, an inclined first waist-shaped hole may be provided on the first slide plate 634, and an inclined second waist-shaped hole may be provided on the second slide plate 633. The right end of the first clamp arm 631 slides in the first waist-shaped hole, and the right end of the second clamp arm 638 slides in the second waist-shaped hole. By driving the first slide plate 634 and the second slide plate 633 to slide in the left-right direction, the first clamp arm 631 and the second clamp arm 638 can be clamped or opened directly without providing an elastic member.

[0060] Reference Figure 8 and Fig. 9 In order to adjust the minimum spacing between the first shaping surface 661 and the second shaping surface, a positioning assembly 426 is provided. The positioning assembly 426 includes a first positioning block 651, a second positioning block 652, a fixing seat 653, a second rotating shaft 654, a second micrometer 655 and a first micrometer 656. The fixing seat 653 is fixed to the top plate 413 by screw locking, and the first micrometer 656 includes a first micrometer screw 671 and a first fixed scale portion 672. The first fixed scale portion 672 is fixed to the fixing seat 653, and the first micrometer screw 671 and the first fixed scale portion 672 are threadedly matched. The first positioning block 651 is rotatably connected to the fixing seat 653 through the second rotating shaft 654, and the lower end of the first positioning block 651 can abut against the first slide plate 634, and the upper end of the first positioning block 651 abuts against the first micrometer screw 671.

[0061] Therefore, by adjusting the extension length of the first micrometer screw 671, the rotation position of the first positioning block 651 can be changed, thereby adjusting the limit position of the first slide plate 634 that can slide to the left, thereby adjusting the final clamping position of the first clamping arm 631.

[0062] The matching relationship between the second micrometer 655 and the second positioning block 652 is similar to the matching relationship between the first micrometer 656 and the first positioning block 651, and will not be repeated here.

[0063] By adjusting the minimum distance between the first shaping surface 661 and the second shaping surface, pins 810 of different widths can be accommodated, thereby avoiding inadequate adjustment or over-clamping of the pins 810.

[0064] In addition, a groove 662 is provided on the first positioning block 651 , and the groove 662 can avoid the calibration block 612 , so that the first shaping surface 661 enters the calibration port 614 , thereby calibrating the pin 810 into place.

[0065] Combined with the above, refer to Figure 2 , Figure 5 and Figure 7After the relay 800 with the pin 810 is placed on the loading platform 100, the second driving component 200 inserts the pin 810 on the front side of the relay 800 into the calibration port 614. Because the distance between the first calibration surface 613 and the second calibration surface 615 gradually decreases along the direction in which the pin 810 is inserted into the calibration port 614, the pin 810 will complete the alignment calibration in two bending directions during the insertion into the calibration port 614 (the pin will not bend upward or downward). After the pin 810 is inserted into the calibration port 614, under the action of the first driving component 425, the first shaping surface and the second shaping surface 645 approach the pin 810 and fit with the pin 810, completing the alignment calibration in the other two bending directions (the pin will not bend to the left or right). At this time, the pin has been completely calibrated, and then the first shaping surface and the second shaping surface 645 are separated from the pin 810 under the action of the first driving component 425, and the second driving component 200 makes the pin 810 disengage from the calibration port 614, completing the calibration operation of the front side pin 810.

[0066] Afterwards, the third driving component 300 moves the calibration component 400 backwards by a certain distance, so that the pin 810 on the front side of the relay 800 is aligned with the calibration port 614, and then repeats the above-mentioned actions to complete the calibration of the pin 810 on the back side. The entire calibration process is a standardized and automated operation, with high calibration efficiency and good consistency of pins.

[0067] Reference Figure 2 In a further embodiment of the invention, four calibration units 420 are arranged along the front-to-back direction, and four relays 800 are also placed along the front-to-back direction on the loading platform 100. Thus, the pin calibration device can complete the pin calibration of four relays 800 at one time, and the calibration efficiency is high.

[0068] Of course, the number of calibration units 420 can be set as needed. For example, the number of calibration units 420 can also be 3, 5, or other numbers.

[0069] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
