[0029] The features and performance of the electronic circuit board welding positioning tool of the present application are further described in detail below in conjunction with the embodiments.

[0030] like Figure 1 、 Figure 2 and Figure 3As shown, the embodiment of the present application provides an electronic circuit board welding positioning tool, which includes a first support plate 100, a second support plate 110 arranged parallel to the first support plate 100, four columns 120, two pairs of clamping blocks 130 and a clamping mechanism, the bottom and bottom of the four columns 120 are respectively connected to the top and bottom four corners of the first support plate 100 and the second support plate 110, and the second support plate 110 is provided with two pairs of strip holes 150 corresponding to the clamping blocks 130. Each strip hole 150 extends along the length direction of the second support plate 110, and the two pairs of strip holes 150 are arranged at intervals along the width direction of the second support plate 110, and each pair of strip holes 150 is arranged at intervals. 50 are arranged at intervals along the length direction of the second support plate 110, and two connecting seats 140 are provided between the first support plate 100 and the second support plate 110. The bottoms of the two clamping blocks 130 in each pair of clamping blocks 130 pass through the corresponding strip holes 150 respectively and are connected to the tops of the two connecting seats 140. The tops of each clamping block 130 extend above the second support plate 110. The clamping mechanism is used to drive the two connecting seats 140 to move toward or away from each other, so as to drive the tops of each pair of clamping blocks 130 to move along the corresponding strip holes 150 to clamp or release the two ends of the circuit board; the adjacent sides of each pair of clamping blocks 130 are respectively provided with a clamping groove 170 for clamping the two ends of the circuit board.

[0031] Among them, the clamping mechanism includes vertical plates 160 respectively provided on the top surfaces of both ends of the first support plate 100, and two parallel guide rods 210 are connected between the two vertical plates 160, and the two ends of each guide rod 210 are respectively connected to the two vertical plates 160, and a rack 220 is slidably sleeved on each guide rod 210. The top surface of the first support plate 100 is connected to a gear 230 respectively meshed with the two racks 220 through a gear shaft 320. When the gear 230 rotates, it drives the two racks 220 to slide along the corresponding guide rods 210 toward each other or away from each other. A spring 310 is respectively provided on the two guide rods 210, and the two ends of the spring 310 respectively press against the corresponding vertical plate 160 and the rack 220. The two springs 310 are used to push the two racks 220 to move toward each other, and the tops of the two racks 220 are respectively connected to a connecting seat 140, and the gear 230 is connected to a driving mechanism for driving its forward and reverse rotation.

[0032] The drive mechanism includes a V-shaped movable rod 250, the middle portion of which is rotatably connected to the top surface of the first support plate 100 via a rotating shaft 240. One end of the movable rod 250 extends between the first and second support plates 100, 110 and is provided with a strip groove 260. The strip groove 260 runs through the movable rod 250, while the other end of the movable rod 250 extends between the first and second support plates 100, 110 and is connected to an operating handle 290. A movable pin 280 that slides into the strip groove 260 is connected to one of the connecting seats 140 via a connecting block 270. When the movable rod 250 rotates about the rotating shaft 240, the strip groove 260 pushes the movable pin 280 to move, thereby moving the corresponding connecting seat 140 toward or away from the other connecting seat 140. An auxiliary handle 300 is connected to the first support plate 100, located to the side of the operating handle 290.

[0033] The working principle of the electronic circuit board welding positioning tool provided in the embodiment of the present application is as follows: Figure 2 As shown, the operator first holds the operating handle 290 and rotates it clockwise, so that when the operating handle 290 rotates along the rotating shaft 240, it drives the bar groove 260 set at one end to rotate. The rotation of the bar groove 260 drives the movable pin 280 inserted therein to move along the bar groove 260, and causes the movable pin 280 to drive the corresponding connected connecting seat 140 to move away from the other connecting seat 140 through the connected connecting block 270. At this time, the moving connecting seat 140 drives the connected corresponding rack 220 to slide along the corresponding guide rod 210 and compress the spring 310 on the corresponding guide rod 210. When the rack 220 slides along the corresponding guide rod 210, it drives the meshing gear 230 to rotate and then drives the other rack 220 to move, thereby causing the two racks 220 and the corresponding two connecting seats 140 to move away from each other, causing the two racks 220 to slide along the corresponding guide rod 210 respectively and compress the spring 310 on the corresponding guide rod 210, and causing the two connecting seats 140 to drive each pair of clamping blocks 1 30 moves along the corresponding strip holes 150 in the direction away from each other. At this time, the circuit board that needs to be fixed and welded can be moved to the preset position above the second support plate 110. The operator releases the operating handle 290 to stop pushing the connecting seat 140, and the two compressed springs 310 respectively push the two racks 220 to move along the corresponding guide rods 210 toward each other, so that the two connecting seats 140 connected by the two gears 230 drive each pair of clamping blocks 130 to move along the corresponding strip holes 150 toward each other, until the clamping grooves 170 provided on the adjacent sides of each pair of clamping blocks 130 clamp the two ends of the circuit board. At the same time, when the two connecting seats 140 move in the direction of approaching each other, they drive the connecting block 270 to push the movable pin 280 to move, so that the movable pin 280 moves along the strip groove 260 while pushing the movable rod 250 to rotate in the opposite direction and reset. Through the above operation, the circuit board can be fixed quickly, efficiently and stably, thereby effectively improving the efficiency of circuit board welding.

[0034] The first support plate 100 is connected to an auxiliary handle 300 located to the side of the operating handle 290. This allows the operator to grasp the auxiliary handle 300 and the operating handle 290 with one hand and rotate the operating handle 290 clockwise. This ensures stable rotation of the operating handle 290, driving each set of clamping blocks 130 to move away from each other along the corresponding strip-shaped holes 150, opening to clamp and secure the circuit board. Each pair of clamping blocks 130 has a respective engaging slot 170 on one side of the adjacent pair, which ensures stable engagement of the ends of the circuit board when the pairs of clamping blocks 130 move toward each other, thereby securing the circuit board.

[0035] In other optional embodiments, a motor assembly or other driving device may be provided to drive the gear 230 to rotate.

[0036] In other optional embodiments, two, three, four or more anti-slip feet may be provided at the bottom of the first support plate 100. By providing anti-slip feet at the bottom of the first support plate 100, the friction between the first support plate 100 and the work surface or welding platform can be increased through the anti-slip feet, thereby ensuring the stability of the welding process.

[0037] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
