By providing a plurality of product placement grooves 3 on the bottom plate 2, multiple products can be soldered simultaneously, simplifying the operation steps and improving the soldering efficiency. Moreover, a product adjustment part 4 is provided on the product placement groove 3. By adjusting the locking adjustment screw 42, the position of the adjustment slider 41 can be adjusted, and thus the compatible size of the soldered product can be adjusted. Through the convenient adjustable structure design, the tooling can be adapted to weld products of various models, improving the product compatibility of the soldering tooling, reducing the changeover and saving costs.

[0034] Figure 3 shows a schematic structural diagram of the product 5 to be soldered provided by an embodiment of the present utility model. As Figure 3 shown, the product to be soldered is a PCBA board structure, which includes a flexible board end, a circuit board 53 and a connection end. The flexible board end and the connection end are respectively arranged at the front and rear ends. The flexible board end includes a flexible board positioning block 51 and a flexible board 52. The circuit board 53 is connected to the connection end through a rubber pad 54 and a wire harness 55. The rubber pad 54 is used to support the end of the wire harness 55. A connection shell 56 is provided at the connection end. The product to be soldered is placed on the product placement groove 3, and then the soldering operation is carried out.

[0035] Specifically, as Figure 1 , Figure 4 shown, the bottom plate 2 is the support bottom surface of the soldering tooling. Along the transverse length direction of the bottom plate 2, sixteen product placement grooves 3 are evenly arranged. The product placement grooves 3 are sequentially and equidistantly arranged on the bottom plate 2, jointly forming a product loading station. The shape and size of the product placement groove 3 are adapted to the product 5 to be soldered. The product placement groove 3 is used to position and support the product, and sixteen products can be soldered, simplifying the operation steps and improving the soldering efficiency. Each product placement groove 3 is provided with a product adjustment part 4 and a product pressing part 6, and the support size is adjusted and positioned and pressed according to the product model, improving the compatibility of the tooling with products of different shapes.

[0036] In this embodiment, the product placement groove 3 is a long and irregular groove structure, which is adapted to the product 5 to be welded. The product placement groove 3 is used to support the flexible board end and the circuit board 53 of the product 5 to be welded. The end area is a flexible board groove 31 for placing the flexible board end of the product, and the rectangular opening area in the middle area is used to support the circuit board 53 of the product. The middle area is provided with a shaped circuit board opening, and a stepped structure is provided around it to support the circuit board 53; the lower end area of the product placement groove 3 is the positioning and placement area of the product rubber pad 54, and the product adjustment part 4 and the product pressing part 6 are both arranged at the end of the product placement groove 3.

[0037] Furthermore, a flexible board positioning block 32 is arranged at the rear of the flexible board groove 31. The flexible board positioning block 32 is used to position the flexible board end of the product, and at the same time, it can enhance the strength of the bottom plate 2; and a support body is arranged in the middle area to ensure the strength of the bottom plate and prevent it from deforming.

[0038] As Figure 2 shown, the adjustment slider 41 arranged in the product adjustment part 4 is a slidable metal block structure for placing the rubber pad 54. The adjustment slider 41 is longitudinally arranged along the length direction of the product placement groove 3. The adjustment slider 41 is adjusted in position and relatively fastened through a locking adjustment screw 42. When the position of the locking adjustment screw 42 is adjusted in terms of tightness, the adjustment slider 41 can slide left and right within a certain stroke range, so that the local placement width of the product on the product placement groove 3 can be adjusted through the product adjustment part 4.

[0039] Specifically, an adjustment hole 43 is arranged at the end of the adjustment slider 41. The adjustment hole 43 is a waist-shaped hole structure arranged horizontally. The adjustment hole 43 penetrates through the adjustment slider 41. The length direction of the adjustment hole 43 matches the moving direction of the adjustment slider 41, and the sliding distance of the adjustment slider 41 is adapted to the horizontal length of the adjustment hole 43; a threaded hole 44 is arranged at the lower end of the adjustment hole 43. The threaded hole 44 is arranged on the bottom plate 2 at the bottom. The threaded hole 44 is used to install the locking adjustment screw 42. The adjustment hole 43 is arranged directly above the threaded hole 44, and the size of the adjustment hole 43 is larger than the size of the threaded hole 44. The locking adjustment screw 42 passes through the adjustment hole 43 from above and is connected to the threaded hole 44 below.

[0040] Furthermore, as Figure 4 shown, as a preferred embodiment of the present invention, a metal strip 12 is arranged at the end of the product placement groove 3 of the bottom plate 2. The metal strip 12 is arranged horizontally, and there are sixteen product placement areas evenly distributed on it. The adjustment slider 41 is arranged on the metal strip 12. A total of three adjustment holes 43 are arranged at the left and right ends and the middle of the metal strip 12. A locking adjustment screw 42 is connected to each adjustment hole 43. During adjustment, the metal strip 12 moves as a whole, and then the left and right positions of the adjustment holes 43 are adjusted.

[0041] In this embodiment, the adjustment slider 41 can slide left and right on the base plate 2. When the welded product is a left-type product, first loosen the three locking adjustment screws 42 on the metal strip 12, and then push the adjustment slider 41 on the metal strip 12 to the left until it reaches the end and the locking adjustment screw 42 abuts against the right side of the adjustment hole 43, that is, the right edge of the waist-shaped hole of the adjustment hole 43 is flush with the right edge of the threaded hole 44. Then tighten the three locking adjustment screws 42 into the threaded hole 44 to complete the position adjustment and fixation. When the welded product is a right-type product, loosen the three locking adjustment screws 42 on the metal strip 12, and then push the adjustment slider 41 to the right until it reaches the end and the locking adjustment screw 42 abuts against the left side of the adjustment hole 43, that is, the left edge of the waist-shaped hole of the adjustment hole 43 is flush with the left edge of the threaded hole 44. Then tighten the three locking adjustment screws 42 back into the threaded hole 44 to complete the position adjustment and fixation. Thus, through the cooperation of the adjustment slider 41 and the locking adjustment screws 42, the adjustment and adaptation production of products of different left and right models are realized, the compatibility of the tooling for the welded products is improved, the component changeover is reduced, and the cost is saved.

[0042] As Figure 2 , Figure 4 shown, in this embodiment, a product pressing part 6 is connected to the product placement groove 3. The product pressing part 6 is movably connected to the product placement groove 3 and can abut against the product 5 to be welded.

[0043] Specifically, as Figure 5 shown, a product pressing part 6 is provided on the side of each product placement groove 3. The product pressing part 6 is used to fixedly press the rubber pad 54 at the end of the product placement groove 3 to prevent the product from loosening during the welding process and improve the welding accuracy. The product pressing part 6 includes a rotary pressing head 61. The rotary pressing head 61 includes a cylindrical main body part 612 and an "L-shaped" pressing head structure 611 integrally connected to the main body part. The main body part 612 of the rotary pressing head 61 can rotate circumferentially, and then drive the pressing head structure 611 to rotate synchronously, so that the pressing head structure 611 is located above the rubber pad 54 or rotates away from the rubber pad 54.

[0044] Furthermore, in this embodiment, the main body portion 612 is the part that is pinched when operating with fingers. The main body portion is hollow and internally provided with a pressing screw 613 to fix the rotating press head to the adjusting slider 41 on the tray; the press head structure 611 protrudes outward from the main body portion 612 to press the product; an adjusting spring 614 is arranged inside the main body portion 612 of the rotating press head 61. The adjusting spring 614 is sleeved on the pressing screw 613. The upper end of the adjusting spring 614 is limited by the screw cap at the upper end of the pressing screw 613, and the lower end of the adjusting spring 614 is restricted by the lower part of the main body portion 612 and does not contact the metal block on the tray. By providing the adjusting spring 614, the rotating press head 61 can be lifted while having a downward pressure itself, and the rotating press head 61 can perform axial expansion and contraction. Thus, when the press head structure 611 of the rotating press head 61 rotates in place, it can press the rubber pad area of the product under the action of the adjusting spring 614.

[0045] Under normal conditions, the adjusting spring 614 is basically in a natural state and not under force; when the main body portion 612 is pinched and lifted, the adjusting spring 614 is compressed and under force, and when the main body portion 612 is released, the main body portion 612 returns to the normal state under the spring force of the adjusting spring 614.

[0046] When operating the product pressing portion 6, first hold the main body portion 612 of the upper part of the rotating press head 61, then pull the press head upward forcefully and then rotate it circumferentially. At this time, the adjusting spring 614 is compressed, and the press head structure 611 is lifted as a whole and can rotate freely in the left and right directions. After rotating the press head structure 611 of the rotating press head 61 above the rubber pad 54 of the product and releasing it, at this time, the press head structure 611 presses the rubber pad 54 of the product under the action of the adjusting spring 614 to prevent it from moving; when it needs to be released, hold the upper part of the rotating press head 61, then pull the press head up forcefully and then rotate it counterclockwise. After rotating until the whole leaves the rubber pad 54 of the product and releasing it, at this time, the rotating press head 61 returns to its original position, and the wire harness can be taken out. Through the product pressing portion 6, products with different shapes and different sizes of rubber pads can be adapted. Moreover, the axial movement dimension of the rotating press head 61 and the compression force of the adjusting spring 614 can also be adapted and adjusted according to actual requirements, thereby further improving the product compatibility of the welding tooling.

[0047] Furthermore, as Figure 1 shown, in this embodiment, the bottom plate 2 is a square plate-like structure. The left area of the bottom plate 2 is the welding product placement area 21, the product placement groove 3 is arranged in the welding product placement area 21, the right area of the bottom plate is the extended placement area 22, and the extended placement area 22 is an extended area arranged on the side of the product placement groove 3. The extended placement area 22 is used to place the wire harness 55 and the connection end structure of the product. The extended placement area 22 is provided with a product wire harness fixing mechanism, and the product wire harness fixing mechanism is used to fix the product wire harness.

[0048] Specifically, as shown in Figure 1 and Figure 6 , the number of settings of the product line harness fixing mechanism is adapted to the number of product placement slots 3, and both are set to sixteen, so that the harness 55 on each product can be fixed. The product line harness fixing mechanism includes a harness clip 7, and the harness clip 7 is perpendicular to the product line harness. The harness 55 can pass through the harness clip 7 and then extend towards the end. The harness clip 7 is made of an elastic material, with a clamping area in the upper part and a harness placement area in the lower part. The product line harness is clamped and fixed by the harness clip 7, and the constraint space of the harness clip 7 can be adjusted as needed, so that different thicknesses of product line harnesses can be compatible through the harness clip 7, further improving the product compatibility of the welding tooling and expanding its applicable range.
