A U-shaped side plate 510 is fixed to the bottom of the arc-shaped slider 509. A circular tube 511 inserted and fitted with the blanking member 6 is fixed to the end of the U-shaped side plate 510;

[0053] Furthermore, a first socket cylinder 512 sleeved and fixed to the telescopic end of the telescopic cylinder 302 is fixed to the bottom of the top plate 501; an electric telescopic rod 513 is fixed to the top of the top plate 501, a top plate 514 is fixed to the telescopic end of the electric telescopic rod 513, and a first lower extension plate 515, a second lower extension plate 516, and a third lower extension plate 517 are sequentially fixed to the bottom of the top plate 514 in a linear array; a second socket cylinder 518 sleeved and fixed to the telescopic end of the electric telescopic rod 513 is fixed to the bottom of the top plate 514; first plugging plates 519, second plugging plates 520, and third plugging plates 521 adapted to the transverse grooves 508 are sequentially fixed to the bottoms of the first lower extension plate 515, the second lower extension plate 516, and the third lower extension plate 517; first arc-shaped blocks 522, second arc-shaped blocks 523, and third arc-shaped blocks 524 are sequentially fixed to the tops of the first plugging plates 519, the second plugging plates 520, and the third plugging plates 521; first rings 525, second rings 526, and third rings 527 arranged concentrically are fixed to the top of the top plate 501, and first arc-shaped openings 528, second arc-shaped openings 529, and third arc-shaped openings 530 adapted to the first arc-shaped blocks 522, the second arc-shaped blocks 523, and the third arc-shaped blocks 524 are sequentially opened at the tops of the first rings 525, the second rings 526, and the third rings 527; a plurality of first grooves 531 are arranged in a circumferential array at the tops of the first rings 525, the second rings 526, and the third rings 527, and positioning insertion holes 532 extending downward are opened inside the plurality of first grooves 531; an L-shaped baffle 533 is fixed to the top of the arc-shaped slider 509, a sliding rod 534 adapted to the positioning insertion hole 532 is slidably fitted through the outer top of the L-shaped baffle 533, a pulling circular plate 535 is fixed to the top of the sliding rod 534, and a movable spring 536 sleeved on the sliding rod 534 is fixed between the pulling circular plate 535 and the L-shaped baffle 533.

[0054] The specific application of the first embodiment is as follows: When performing bead spot welding on the automotive lamp substrate to be spot welded in the circumferential direction, in combination with the feeding process of the beads to be spot welded, pull the pulling circular plate 535, drive the sliding rod 534 to move upward on the outer top of the L-shaped baffle 533, so that the movable spring 536 fixedly connected between the pulling circular plate 535 and the L-shaped baffle 533 is compressed. At this time, start sliding the arc-shaped slider 509 slidably arranged inside the first circular ring groove 502, so that the arc-shaped slider 509 can perform circumferential circular sliding on the outer circle inside the first circular ring groove 502. When the arc-shaped slider 509 can perform circumferential circular sliding on the outer circle inside the first circular ring groove 502, the sliding rod 534 slides from inside the first groove 531 to the adjacent first groove 531 until the bottom of the sliding rod 534 is aligned with the positioning jack 532 opened inside the adjacent first groove 531. Then release the pulling circular plate 535, so that the sliding rod 534 moves downward under the reset action of the movable spring 536 and finally inserts into the adjacent positioning jack 532, and the feeding operation of the beads to be spot welded is carried out in this way. Repeat this process to complete the circumferential spot welding process in the whole process, avoiding the inconsistent intervals between multiple beads to be spot welded on the same circular track during circumferential spot welding, which affects the later irradiation effect and preventing the phenomenon of uneven lighting during its later use;

[0055] When the spot welding process of the outermost circle is completed, start the electric telescopic rod 513 to drive the top plate 514 to move upward, so that the first sealing plate 519, the second sealing plate 520, the third sealing plate 521 and the first arc-shaped block 522, the second arc-shaped block 523, the third arc-shaped block 524 are synchronously separated from the transverse groove 508 and the first arc-shaped opening 528, the second arc-shaped opening 529, the third arc-shaped opening 530. Then pull the sliding rod 534 so that the bottom of the sliding rod 534 is higher than the heights of the first circular ring 525, the second circular ring 526, the third circular ring 527, and then push the arc-shaped slider 509 so that the arc-shaped slider 509 performs circumferential sliding inside the first circular ring groove 502 and approaches the inside of the transverse groove 508 connected to the first circular ring groove 502. Then push the arc-shaped slider 509 inside the transverse groove 508 so that the arc-shaped slider 509 slides from the first circular ring groove 502 into the second circular ring groove 503, and then performs the same circumferential circular motion in the second circular ring groove 503 as the arc-shaped slider 509 in the first circular ring groove 502, and combines the feeding operation of the beads to be spot welded in this way. Repeat this process to complete the circumferential spot welding process of the middle circle in the whole process, avoiding the inconsistent intervals between multiple beads to be spot welded on the same circular track during circumferential spot welding, which affects the later irradiation effect and preventing the phenomenon of uneven lighting during its later use;

[0056] After the spot welding process of the middle circle is completed, the electric telescopic rod 513 is started again to drive the top plate 514 to move upward, so that the first blocking plate 519, the second blocking plate 520, the third blocking plate 521 and the first arc block 522, the second arc block 523, and the third arc block 524 are synchronously separated from the transverse groove 508 and the first arc opening 528, the second arc opening 529, and the third arc opening 530, and then the sliding rod 534 is pulled so that the bottom of the sliding rod 534 is higher than the height of the first circular ring 525, the second circular ring 526, and the third circular ring 527, and then the arc slider 509 is pushed so that the arc slider 509 slides circumferentially inside the second circular groove 503 and approaches the first circular groove 503. The arc-shaped slider 509 in the transverse groove 508 is then pushed inside the two circular grooves 503, so that the arc-shaped slider 509 slides from the second circular groove 503 to the third circular groove 504, and then performs the same circumferential circular motion of the arc-shaped slider 509 in the first circular groove 502 in the third circular groove 504, and combines this with the blanking operation of the lamp beads to be spot-welded, so as to complete the inner circle circumferential spot welding process in the whole process, so as to avoid the inconsistent spacing between the multiple lamp beads to be spot-welded on the same circular trajectory during the circumferential spot welding, which affects the later illumination effect and prevents the uneven lighting when it is used later;

[0057] When the spot welding operation is performed, when the lamp beads to be spot welded are being unloaded, the telescopic cylinder 302 is started, driving the unloading tool 2 fixed at the telescopic end of the telescopic cylinder 302 to synchronously descend until the bottom of the unloading part 6 is close to the surface of the substrate of the automobile lamp to be spot welded after the straightening and clamping positioning (there is a certain height between the unloading part 6 and the surface of the substrate of the automobile lamp to be spot welded, and the height is slightly greater than the height of the lamp beads to be spot welded), and then the unloading operation of the lamp beads to be spot welded is performed. After the unloading operation of the lamp beads to be spot welded is completed, the telescopic cylinder 302 is started, driving the unloading tool 2 fixed at the telescopic end of the telescopic cylinder 302 to synchronously move upward, so as to perform subsequent circumferential unloading operations.

[0059] The specific application of the second embodiment is as follows: After the automotive lamp substrate to be spot-welded is correctly positioned and clamped, the pull rod 619 is pulled to drive the hinge arm 616 hinged between the first hinge seat 615 and the second hinge seat 618 to perform a pressing operation, so that the rectangular column 610 moves downward inside the rectangular placement groove 605, and simultaneously compresses the return spring 613 fixedly connected between the top ring plate 611 and the first ear plate 602, causing the top ring plate 611 to move downward between the two guide rods 612, thereby performing a pressing and discharging operation on each of the multiple lamp beads to be spot-welded stacked inside the rectangular placement groove 605 (during the pressing and discharging process, the pre-tightening force of the elastic spring 609 ensures that the displacement plate 606 opens only under the gravity of the bottommost lamp bead). When performing a pressing and discharging operation on each of the multiple lamp beads to be spot-welded stacked inside the rectangular placement groove 605, the bottom of the rectangular column 610 exerts pressure on the multiple stacked lamp beads to be spot-welded, causing the bottom of the bottommost lamp bead to be spot-welded to simultaneously exert a pressing force on the multiple displacement plates 606 with chamfered sides, thereby simultaneously compressing the multiple elastic springs 609 fixedly connected between the side baffle 607 and the blanking cylinder 601, causing the multiple displacement plates 606 to simultaneously perform a radial linear motion inside the rectangular placement groove 605, so that the bottommost lamp bead to be spot-welded falls onto the surface of the automotive lamp substrate to be spot-welded after being correctly positioned and clamped. After the bottommost lamp bead to be spot-welded falls onto the surface of the automotive lamp substrate to be spot-welded after being correctly positioned and clamped, the downward movement of the rectangular column 610 inside the rectangular placement groove 605 stops. At this time, the compressed elastic spring 609 starts to reset, and the multiple displacement plates 606 simultaneously perform a reverse radial linear motion inside the rectangular placement groove 605 until the multiple displacement plates 606 return to their initial positions, thereby supporting the adjacent lamp beads to be spot-welded for subsequent circumferential spot-welding operations.

[0060] Embodiment 3, please refer to Figures 1-13, in the third embodiment, the following improvements are made on the basis of the first embodiment. Specifically, a positioning cylinder 303 is fixed to the top of the mounting base plate 301, a positioning ring 304 is fixed to the top of the positioning cylinder 303, a placement table 305 is fixed inside the positioning cylinder 303 on the top of the mounting base plate 301, and a number of side plates 306 are fixed inside the positioning cylinder 303 on the top of the mounting base plate 301. A clamping rod 307 is slidably penetrated through the side surface of the side plate 306. One end of the clamping rod 307 is fixed with an L-shaped clamping plate 308, and a sliding plate 309 is fixed to the opposite end surface of the clamping rod 307. A stabilizing spring 310 sleeved on the clamping rod 307 is fixed between the sliding plate 309 and the side plate 306. An extension rod 311 is fixed to the side surface of the sliding plate 309, and a contact ball 312 is fixed to the end of the extension rod 311; the rotating member 4 includes two rotating rings 401 that are hinged together. Second ear plates 402 that are mutually attached are fixed to the ends of the two rotating rings 401, and the two second ear plates 402 are fixedly connected by bolts; rotating grooves 403 that are rotatably fitted on the positioning ring 304 are formed inside the two rotating rings 401. A number of second threaded columns 404 are fixed to the tops of the two rotating rings 401, and a semi-circular ring 405 is inserted and fixed between the number of second threaded columns 404. A number of second grooves 406 are formed inside the semi-circular ring 405; a number of third threaded columns 407 are fixed to the bottoms of the two rotating rings 401, and a gear ring 408 is inserted and fixed between the number of third threaded columns 407; a rotating shaft 313 is fixed to the top of the mounting base plate 301, a rotating plate 314 is rotatably fitted on the circumferential side of the rotating shaft 313 through a bearing, and a ratchet tooth 315 adapted to the gear ring 408 is fixed to the side surface of the rotating plate 314 (the tooth shape of the gear ring 408 is designed as a one-way helical tooth, and only allows clockwise rotation when meshing with the ratchet tooth 315). A fixing plate 316 is fixed to the top of the mounting base plate 301, and an arc spring 317 is fixed between the fixing plate 316 and the rotating plate 314.

[0061] The specific application of the third embodiment is as follows: before spot welding the round substrate in the automobile lamp, the automobile lamp substrate to be spot welded is horizontally placed on the top of the placement table 305, and the rotating member 4 is started to rotate, so that the rotating groove 403 in the rotating member 4 synchronously performs a unidirectional circular rotation on the peripheral side of the positioning ring 304, so that a plurality of contact balls 312 respectively slidingly matched on the inner walls of a plurality of second grooves 406 gradually slide toward the inner wall of the semicircular ring 405 (the synchronous plugging process of the two semicircular rings 405 can form a complete circular ring), so that the stabilizing spring 310 fixedly connected between the sliding plate 309 and the side plate 306 is compressed, driving the plurality of clamping rods 307 to synchronously rotate. The plurality of side plates 306 perform radial linear motion (when the plurality of clamping rods 307 synchronously perform radial linear motion on the plurality of side plates 306, they are limited by the sliding cooperation between the two limiting rails provided on the peripheral sides of the clamping rods 307 and the two limiting grooves provided on the side plates 306, to prevent the plurality of clamping rods 307 from rotating circumferentially when the plurality of clamping rods 307 synchronously perform radial linear motion on the plurality of side plates 306, thereby affecting the subsequent clamping and straightening process. Straightening refers to the process of keeping the automobile lamp substrate to be spot-welded horizontal and centered by means of the plurality of clamping rods 307), thereby performing a straightening and clamping operation on the automobile lamp substrate placed on the top of the placement table 305;

[0062] When the above-mentioned straightening and clamping operation is performed on the automobile lamp substrate before spot welding, the rotating groove 403 in the rotating member 4 synchronously performs a unidirectional circumferential rotation on the peripheral side of the positioning ring 304, and the gear ring 408 plugged and fixed on the third threaded columns 407 synchronously performs a unidirectional circumferential rotation. When the gear ring 408 performs a synchronous unidirectional circumferential rotation, the plurality of teeth arranged on the peripheral side surface will generate a toggling force on the ratchet 315 fixed on the side surface of the rotating plate 314, thereby synchronously compressing the arc spring 317 fixedly connected between the fixing plate 316 and the rotating plate 314, so that the rotating plate 314 is rotated in a unidirectional manner. The plate 314 rotates circumferentially close to the rotating shaft 313 on the peripheral side of the rotating shaft 313 until the automobile lamp substrate is straightened and clamped, and the arc spring 317 is reset. At this time, the ratchet 315 fixed on the side of the rotating plate 314 will slide from the teeth on the gear ring 408 to the adjacent multiple teeth, so as to avoid the reverse rotation of the entire rotating member 4 on the positioning ring 304 during the later spot welding, resulting in the separation of the multiple straightening and clamping L-shaped clamping plates 308 from the peripheral side of the automobile lamp substrate, so as to avoid the shaking of the automobile lamp substrate during the later spot welding, thereby improving the later spot welding effect;

[0063] After the spot welding operation of the lamp beads is completed, start pulling the rotating plate 314 outwards, so that the ratchet 315 fixed on one side of the rotating plate 314 is separated from the teeth on the gear ring 408, and then rotate the rotating member 4 in the reverse direction, so that the rotating groove 403 in the rotating member 4 rotates in the reverse direction synchronously on the circumferential side of the positioning ring 304, so that a number of contact balls 312 respectively slidingly fitted on the inner walls of a number of second grooves 406 gradually slide from the inner wall of the semi-circular ring 405 into the second grooves 406, and in combination with the elastic reset force of the stable spring 310, drive a number of clamping rods 307 to perform reverse radial linear motion synchronously on a number of side plates 306, so that a number of L-shaped clamping plates 308 are separated from the circumferential side of the automotive lamp substrate synchronously, so as to take the automotive lamp substrate after spot welding is completed, so as to perform continuous spot welding operations in the later stage.
