[0003] The actual device for wiring and welding the refrigeration fins mainly clamps a single refrigeration fin wiring through an electric clamping device, and welds the front end of the refrigeration fin wiring combined with the refrigeration fin through a welding device that moves synchronously with the electric clamping device. The subsequent welding of the refrigeration fin wiring is achieved by gradually moving the electric clamping device and the welding device as a whole and repeating the above steps.

[0004] Although the above technical solution can perform welding connection on each refrigeration plate connection, due to the large number of refrigeration plate connections during the welding process and the need for precise positioning of the welding position of the refrigeration plate connections and the top of the refrigeration plate, the method of clamping the refrigeration plate connections and welding them in turn is time-consuming and labor-intensive, and it is difficult to ensure the positioning accuracy of the refrigeration plate connections and the top of the refrigeration plate; in addition, since the refrigeration plate connections are in a randomly bent state before welding, the front end of the refrigeration plate connections may not be straight, resulting in the refrigeration plate connections being unable to fit tightly with the welding position on the top of the refrigeration plate during the welding process, which in turn leads to cold welding, affecting the welding quality and the use of the refrigeration plate after welding is completed.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0034] See also Figure 1-Figure 2 A high-temperature welding connection device for electronic components includes a positioning frame 1, a positioning groove 11 is arranged in the positioning frame 1, a No. 1 cylinder 2 is fixed to the top fixed end, a positioning unit 3 for positioning the electronic components is arranged in the positioning groove 11, a collection plate 21 is fixed to the pushing end of the No. 1 cylinder 2, a clamping unit 4 for clamping the wiring of the electronic components is arranged on the collection plate 21, and a welding unit 5 is arranged on the front side of the collection plate 21.

[0035] The present invention positions the refrigeration plate by the positioning unit 3, and simultaneously positions multiple refrigeration plate wirings equidistantly and synchronously by the clamping unit 4, so that the refrigeration plate wirings can adapt to the sizes of refrigeration plates of different sizes, so as to cooperate with the welding unit 5 to weld each positioned refrigeration plate wiring in turn. Specifically, the refrigeration plate is first positioned by the positioning unit 3, and the position of the refrigeration plate for welding wiring is aligned with the clamping unit 4, and then the multiple refrigeration plate wirings are positioned and clamped by the clamping unit 4. After the positioning and clamping of the refrigeration plate wiring is completed, the No. 1 cylinder 2 is controlled to push the assembly plate 21 and the clamping unit 4 downward until the refrigeration plate wiring moves to the welding position, and then the welding unit 5 is controlled to weld the refrigeration plate wiring and the refrigeration plate from left to right in turn.

[0036] See also Figure 1 , Figure 3 and Fig.11 The positioning unit 3 includes a threaded rod 31 threadedly connected to the front side wall of the positioning frame 1, a pushing plate 311 is fixed to the rear end of the threaded rod 31, and a crank is fixed to the front end of the threaded rod 31. The left and right sides of the positioning groove 11 are symmetrically connected through elastic telescopic rods with bent positioning plates 312 for positioning the left and right positions of electronic components.

[0037] The positioning unit 3 is used to adjust the position of the cooling plate, so that the position of the cooling plate is adjusted and ensure that the welding position at the top of the cooling plate is located below the clamping unit 4. Specifically, the cooling plate to be welded is first placed from top to bottom in the positioning groove 11. At this time, the bent positioning plates 312 on both sides will be pressed outward by the upper resistance of the cooling plate, so that the cooling plate is centered by the elastic force of the elastic telescopic rod. Then the operator shakes the handle to rotate the threaded rod 31, and drives the pushing plate 311 to push the cooling plate backward, thereby moving the welding position at the top of the cooling plate to below the clamping unit 4 and completing the positioning of the cooling plate.

[0038] See also Figure 2 , Figure 4 and Figure 5 The clamping unit 4 includes horizontal slide grooves opened on the left and right sides of the collecting plate 21, and each horizontal slide groove is slidably connected with a plurality of limit sliders 41, and a movable column 411 is fixed at the bottom of the limit slider 41, and a fixed column 412 is installed at the bottom of the collecting plate 21 and at the center of the two horizontal slide grooves. The fixed column 412 and the movable column 411 are both rotatably installed with two rotating rods 413, and all the rotating rods 413 together form a scissor-type structure, and clamping elements 42 are arranged at the bottom of the fixed column 412 and the bottom of the movable column 411, and a power element 43 for cooperating with the clamping element 42 for stable clamping is arranged on the rear side of the collecting plate 21; an adjusting stud for adjusting the position of the clamping element 42 is threadedly connected on the collecting plate 21, and the left end of the adjusting stud is connected to the limit slider 41 on the right.

[0039] The clamping unit 4 is used to synchronously clamp the refrigeration fin wiring, and at the same time, the scissor-type structure cooperates with the adjusting stud to synchronously adjust the position of the limit slider 41 equidistantly, thereby equidistantly adjusting the position of the clamping element 42, so that the clamped refrigeration fin wiring can correspond one by one to the welding position of the top of the refrigeration fin that has been positioned. At the same time, the method of synchronously clamping and positioning the refrigeration fin wiring can also improve the positioning accuracy.

[0040] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.10 The clamping element 42 includes a U-shaped frame 421 fixed at the bottom of the fixed column 412 or the movable column 411, a horizontal rod 422 is connected between the two vertical sections of the U-shaped frame 421, and a clamping jaw 423 is symmetrically slidably connected to the horizontal rod 422, a horizontal spring is connected between the two clamping jaws 423, and the opposite sides of the two clamping jaws 423 are connected to a limiting structure; the limiting structure includes an outer sleeve block 424 and an inner sleeve block 425 respectively fixed on the opposite sides of the left and right clamping jaws 423, a left pressure block 426 and a right pressure block 427 are respectively fixed on the opposite sides of the two clamping jaws 423 and located on the upper side of the outer sleeve block 424, the left pressure block 426 and the right pressure block 427 are respectively provided with left-right symmetrical slopes at the bottom, and the positions of the left pressure block 426 and the right pressure block 427 are staggered.

[0041] The clamping element 42 can be pushed by the power element 43 and can position and clamp the refrigeration fin wiring. At the same time, the outer cover block 424 and the embedded block 425 cooperate with the left pressure block 426 and the right pressure block 427 to ensure that the positions of all clamped refrigeration fin wirings are consistent. At the same time, the positioning of the refrigeration fin wiring by the staggered left pressure block 426 and the right pressure block 427 can not only adapt to refrigeration fin wirings of different sizes, but also make the clamping of the refrigeration fin wiring more stable.

[0042] Specifically, when the refrigeration plate is positioned, the rotation of the adjustment stud is controlled according to the size of the refrigeration plate and the welding position of the refrigeration plate to adjust the position of the limit slider 41 on the right side. After the adjustment is completed, all the limit sliders 41 will adjust the position synchronously due to the scissor-type structure composed of all the rotating rods 413. Then the operator places all the refrigeration plate wiring on the top of the outer sleeve block 424 and the inner sleeve block 425 in turn, and then pushes the two clamps 423 by controlling the power element 43, so that the clamps 423 move toward each other. At this time, the outer sleeve block 424 will be sleeved on the inner sleeve block 425 and against the bottom of the refrigeration plate wiring. At the same time, the left pressure block 426 and the right pressure block 427 will move toward each other and staggered, and the left pressure block 426 and the right pressure block 427 will press the refrigeration plate wiring with the bottom, thereby completing the clamping and positioning of the refrigeration plate wiring, so that all the positioned refrigeration plate wiring is stable and at the same height.

[0043] See also Figure 5-Figure 9 The power element 43 includes an L-shaped lower extension plate 431 fixed to the rear side of the collecting plate 21, a No. 2 cylinder 432 is installed on the front side of the vertical section of the L-shaped lower extension plate 431, and a matching plate 433 is fixed to the pushing end of the No. 2 cylinder 432. The matching plate 433 is symmetrically provided with matching slide grooves, each of which is slidably connected with a matching slider 41 in the corresponding horizontal slide groove, and a moving plate 434 is fixed to the front end of each matching slider and the center position of the front side of the matching plate 433. A positioning seat 435 is fixed to the top of the moving plate 434 on the matching slider, and a positioning rod 436 is fixed to the rear side of each U-shaped frame 421 and the position corresponding to the positioning seat 435. The positioning rod 436 slides through the positioning seat 435, and a pushing rod 437 for pushing each clamp 423 inward is symmetrically fixed to the front side of the moving plate 434, and a pushing slope for pushing the clamp 423 is provided on the side of the pushing rod 437.

[0044] The power element 43 also includes a rear-pushing structure connected between each clamping jaw 423 and the corresponding pushing rod 437, and the rear-pushing structure includes a rear extension rod 438 fixed on the rear side of each clamping jaw 423, a sliding sleeve 439 is sleeved on the rear extension rod 438, and arc-shaped clamping plates 440 are symmetrically fixed to the opposite sides of the two sliding sleeves 439, a circular plate 441 is fixed to the rear end of the rear extension rod 438, and a compression spring is connected to the circular plate 441 and the sliding sleeve 439, and an extension plate 442 is fixed to the rear side of the clamping jaw 423 and above the sliding sleeve 439, and track sleeves 443 are rotatably installed on the opposite sides of the two extension plates 442, and the track sleeves 443 are symmetrically provided with track grooves from top to bottom, a lower slide rod 444 is fixed to the side of the sliding sleeve 439 at the position corresponding to the track groove, and an upper slide rod 446 is fixed to the side of the pushing rod 437 at the position corresponding to the track groove through a connecting block 445.

[0045] The power element 43 is used to push the clamp 423 so that the clamp 423 completes the clamping of the cooling fin wiring, and the movable plate 434 can also adaptively align the position of the clamping element 42 through the positioning rod 436 and the positioning seat 435, so as to ensure that the clamp 423 is pushed accurately, and at the same time, the rear end of the cooling fin wiring can be pushed backwards by the rear stroking structure during the clamping process, so as to avoid the situation that the rear end of the cooling fin wiring is affected by excessive bending and the fitting of the front end of the cooling fin wiring with the welding position of the cooling fin is avoided.

[0046] Specifically, after the personnel have placed all the refrigeration plate wiring in sequence on the top of the outer jacket block 424 and the inner embedded block 425, the second cylinder 432 is controlled to drive the matching plate 433 to move forward. At this time, due to the combined limiting effect of the positioning seat 435 and the positioning rod 436, the moving plate 434 is just aligned with the front clamping claw 423. When the moving plate 434 moves forward with the matching plate 433, the two pushing rods 437 will push the clamping claw 423 respectively through the pushing slope, thereby cooperating with the left pressing block 426 and the right pressing block 4 27 completes the position fixation of the cooling plate wiring, and in the process of the push rod 437 moving forward, the push rod 437 drives the upper slide rod 446 to move forward, so that the track sleeve 443 rotates and pushes the lower slide rod 444 together with the sliding sleeve 439 backward, so that the two arc-shaped clamping plates 440 move backward while closing to the cooling plate wiring as the clamping claws 423 move towards each other, and then the rear end of the cooling plate wiring is straightened by the arc-shaped clamping plate 440, so that the rear end of the cooling plate wiring is away from the cooling plate position.

[0047] It should be noted that since the front end of the cooling plate is used for welding with the cooling plate, the rear end of the cooling plate connection does not need to be above the cooling plate, and the power element 43 and the rear-pushing structure will not be at the cooling plate welding position, so the size of the cooling plate will not hinder the movement of the power element 43 and the rear-pushing structure.

[0048] See also Figure 4 , Figure 5 , Figure 8 and Fig.10 The welding unit 5 includes a horizontal slide rail 51 fixed on the front side of the collection plate 21, and the horizontal slide rail 51 is connected to a collection block 511 through an electric slider. A connecting element 52 is arranged at the bottom of the collection block 511, and a welding gun 512 is installed on the connecting element 52. The welding gun 512 is in an inclined state. A pressing element 53 driven by the connecting element 52 is arranged on the clamping element 42. The electronic component wiring is pressed by the pressing element 53 and the electronic component wiring is brought into close contact with the welding position. A blocking element 54 for limiting the movement of the electric slider is arranged on the top of the collection plate 21.

[0049] The welding unit 5 is used to weld tightly fitting refrigeration plates and refrigeration plate wiring. At the same time, the pressing element 53 cooperates with the connecting element 52 to ensure that the refrigeration plate wiring and the refrigeration plate welding position are tightly fitted, so as to facilitate the welding gun 512 to weld the refrigeration plate wiring and the refrigeration plate to prevent the occurrence of cold welds. At the same time, the blocking element 54 can accurately control the movement of the welding gun 512, so that the welding gun 512 is aimed at each refrigeration plate wiring for welding, ensuring the welding accuracy and the cooperation between the pressing element 53 and the connecting element 52.

[0050] See also Figure 5 , Figure 8 and Fig.10 The pressing element 53 includes a front extension rod 531 which is symmetrically fixed on the front side of the clamping element 42. A horizontal sliding sleeve 532 is sleeved on each front extension rod 531. A round cap 533 is fixed to the front end of each front extension rod 531. A connecting spring is connected between the round cap 533 and the horizontal sliding sleeve 532. Inner grooves are symmetrically arranged on the opposite sides of the two horizontal sliding sleeves 532. A pressure block 534 is connected to each inner groove through a plurality of inner springs. A pressure inclined block 535 is fixed to the top of each horizontal sliding sleeve 532.

[0051] The connecting element 52 includes an electric push rod 521 fixed at the bottom of the assembly block 511, and a horizontal plate 522 is fixed to the pushing end of the electric push rod 521. The bottom of the horizontal plate 522 is connected to the welding gun 512 through a mounting block 523. A fixing rod 524 is fixed to the rear side of the horizontal plate 522.

[0052] The pressing element 53 is used to cooperate with the connecting element 52 to straighten the front end of the refrigeration fin connection forward and press it downward before welding, thereby ensuring that the front end of the refrigeration fin connection contacts the welding position of the refrigeration fin, and facilitating the welding gun 512 to weld the refrigeration fin connection and the refrigeration fin. At the same time, by pressing the front end of the refrigeration fin connection downward with the pressing rod 526, it can ensure that the welding gun 512 is accurately aligned with the front end of the refrigeration fin connection that has been pressed down for welding, thereby ensuring the welding accuracy.

[0053] Specifically, when the refrigeration fin wiring is positioned and the rear end is straightened backward, the electric slider is controlled to drive the assembly block 511, the connecting element 52 and the welding gun 512 to move to the right synchronously until the blocking element 54 blocks the movement of the assembly block 511, the connecting element 52 and the welding gun 512. At this time, the assembly block 511, the connecting element 52 and the welding gun 512 are just located at the refrigeration fin wiring position, and then the electric push rod 521 is controlled to push the horizontal plate 522 and the pressing bevel block 525 downward, and the pressing bevel block 525 will push the pressed bevel block 535 through the inclined surface on the pressing bevel block 525 and make the pressed bevel block 535 The pressure block 535 moves forward, and the pressure block 535 drives the horizontal sliding sleeve 532 and the pressure block 534 to move forward, so that the front end of the refrigeration plate connection that originally drooped due to gravity is straightened by the upward action of the pressure block 534, and finally the front end of the refrigeration plate connection is pressed downward by the downward pressure rod 526, so that the front end of the refrigeration plate connection is tightly fitted with the welding position of the refrigeration plate, and then the welding gun 512 is controlled to weld the tightly fitted refrigeration plate connection and the refrigeration plate. By making the front end of the refrigeration plate connection and the refrigeration plate tightly fit, the occurrence of cold welding can be avoided.

[0054] See also Figure 4 and Figure 5 and Fig.12 The blocking element 54 includes a connecting column 541 symmetrically fixed to the front end of the top of the assembly plate 21, a front extension plate 542 is fixed to the top of the two connecting columns 541, a No. 3 cylinder 543 is fixed to the bottom of the front extension plate 542, and a lifting plate 544 is fixed to the pushing end of the No. 3 cylinder 543; a telescopic blocking structure is provided on the limit slider 41, and a blocked plate 545 blocked by the telescopic blocking structure is fixed to the top of the assembly block 511; the telescopic blocking structure includes a plate 545 opened at the top of the assembly plate 21 and facing An upper slot should be formed at the position of the horizontal slide slot, and an embedded rod 546 is fixed at the top of the limit slider 41 and corresponds to the upper slot position. An outer frame 547 is provided on the embedded rod 546. A tension spring is connected between the outer frame 547 and the top of the embedded rod 546. A lifting rod 548 is fixed to the front end of the outer frame 547. A blocking plate 549 is fixed to the front end of the lifting rod 548. A blocking plate 549 is also fixed to the center position of the front end of the lifting plate 544. The heights of all blocking plates 549 increase from left to right.

[0055] The blocking element 54 is used to limit the distance that the electric slider drives the assembly block 511, the connecting element 52 and the welding gun 512 to move synchronously to the right, so that the welding gun 512 can be accurately aligned with the refrigeration fin wiring for welding, ensuring the welding accuracy. At the same time, the lifting plate 544 is combined with the elastically retractable embedded rod 546, the outer shell frame 547 and the blocking plate 549, so that the position of the blocking plate 549 accurately corresponds to the refrigeration fin wiring position, further improving the welding accuracy of the welding gun 512 on the refrigeration fin wiring.

[0056] Specifically, when the spacing of the limit slider 41 is adjusted by the scissor-type structure, the embedded rod 546, the outer frame 547 and the lifted rod 548 will move together and be consistent with the spacing of the limit slider 41. At this time, the blocking plate 549 will be consistent with the wiring position of the clamped refrigeration plate.

[0057] When the electric slider is controlled to drive the assembly block 511, the connecting element 52 and the welding gun 512 to move to the right synchronously, the blocked plate 545 will be blocked by the blocking plate 549. At this time, the pressing element 53 is controlled to cooperate with the connecting element 52 to enable the welding gun 512 to weld the refrigeration plate wiring. After the welding is completed, the No. 3 cylinder 543 is controlled to drive the lifting plate 544 to move upward. At this time, due to the lifting effect of the lifting plate 544 on the lifted rod 548, all the lifted rods 548 synchronously drive the blocking plate 549 to rise. At this time, the blocked plate 545 can pass under the nearest blocking plate 549. Then, when the electric slider is controlled to drive the assembly block 511, the connecting element 52 and the welding gun 512 to move to the right synchronously, the blocked plate 545 will be blocked by the second blocking plate 549 from left to right, and then the above operation is repeated until the welding gun 512 completes the welding of all the refrigeration plate wiring.

[0058] The working steps of the present invention are as follows: the first step is to place the refrigeration plate to be welded from top to bottom in the positioning groove 11. At this time, the bent positioning plates 312 on both sides will be pressed outward by the refrigeration plate due to the resistance of the upper part, so that the refrigeration plate is centered by the elastic force of the elastic telescopic rod. Then the operator shakes the handle to rotate the threaded rod 31, and drives the pushing plate 311 to push the refrigeration plate backward, thereby moving the welding position at the top of the refrigeration plate to the bottom of the clamping unit 4 and completing the positioning of the refrigeration plate.

[0059] In the second step, when the refrigeration plate is positioned, the rotation of the adjustment stud is controlled according to the size of the refrigeration plate and the welding position of the refrigeration plate to adjust the position of the limit slider 41 on the right side. After the adjustment is completed, all the limit sliders 41 will adjust their positions synchronously due to the scissor-type structure composed of all the rotating rods 413. Then the operator places all the refrigeration plate connections on the top of the outer cover block 424 and the embedded block 425 in turn.

[0060] Then, the two clamping jaws 423 are pushed by controlling the power element 43, so that the clamping jaws 423 move toward each other, and the outer block 424 will be put on the inner block 425 and press against the bottom of the refrigeration fin connection. At the same time, the left pressure block 426 and the right pressure block 427 will move toward each other and staggered, and the left pressure block 426 and the right pressure block 427 will press against the refrigeration fin connection with the bottom, thereby completing the clamping and positioning of the refrigeration fin connection, so that all the positioned refrigeration fin connections are stable and located at the same height, and the arc-shaped clamping plate 440 in the power element 43 will also straighten the rear end of the refrigeration fin connection, so that the rear end of the refrigeration fin connection is away from the refrigeration fin position.

[0061] The third step is, when the refrigeration fin wiring positioning is completed and the rear end is straightened backwards, control the electric slider to drive the assembly block 511, the connecting element 52 and the welding gun 512 to move to the right synchronously until the blocking element 54 blocks the movement of the assembly block 511, the connecting element 52 and the welding gun 512. At this time, the assembly block 511, the connecting element 52 and the welding gun 512 are just located at the refrigeration fin wiring position.

[0062] The fourth step, when the welding gun 512 corresponds to the position of the refrigeration plate wiring, the electric push rod 521 is controlled to push the horizontal plate 522 and the pressing bevel block 525 downward, and the pressing bevel block 525 will push the compressed bevel block 535 through the inclined surface on the pressing bevel block 525 and make the compressed bevel block 535 move forward, and then the compressed bevel block 535 drives the horizontal sliding sleeve 532 and the compressed block 534 to move forward, so that the front end of the refrigeration plate wiring that originally drooped due to gravity is straightened by the upward action of the compressed block 534, and finally the front end of the refrigeration plate wiring is pressed downward by the downward pressure rod 526, so that the front end of the refrigeration plate wiring is tightly fitted with the welding position of the refrigeration plate, and then the welding gun 512 is controlled to weld the tightly fitted refrigeration plate wiring and the refrigeration plate.

[0063] The fifth step is to wait for the welding gun 512 to complete the welding of the first refrigeration plate connection, control the blocking element 54 to adjust the height of the electric slider displacement block, and then control the electric slider again to drive the assembly block 511, the connecting element 52 and the welding gun 512 to move to the right synchronously until the electric slider stops moving again due to the blocking element 54, and then repeat the above-mentioned operation of the connecting element 52 and the pressing element 53, and repeat this process until the welding gun 512 completes the welding of all the refrigeration plate connections.
