DETAILED DESCRIPTION

[0024] like Figure 1-5 As shown, a high-precision welding device for copper busbar soft connection production in this embodiment includes a base 1, a strip groove 2 is arranged on the top of the base 1, and the strip groove 2 is parallel to the left and right directions. A nozzle 3, a translation module mechanism 4 and an air supply mechanism 5 are arranged in the strip groove 2. The translation module mechanism 4 drives the nozzle 3 to move left and right, and the air supply mechanism 5 delivers air to the nozzle 3. Two clamping mechanisms 6 arranged front and back are arranged on the base 1, and the two clamping mechanisms 6 are symmetrically arranged about the strip groove 2;

[0025] During the use of the device, the base 1 is installed on the working platform of the welding machine, and the base 1 can be driven to move left and right and front and back through the moving device on the working platform. Then, the two copper soft bar workpieces 7 are placed between the two clamping mechanisms 6 with the workpieces 7 being pressed against each other, and the workpieces 7 are fitted with the top of the base 1, and the two workpieces 7 are clamped by the clamping mechanism 6, and the connection between the two workpieces 7 is located directly above the nozzle 3. Then, the base 1 is moved by the moving device on the working table, and the connection between the two workpieces 7 is located directly below the welding device on the welding machine. Then, the connection between the two workpieces 7 is welded by the welding device on the welding machine, and at the same time, the base 1 is moved unidirectionally in the left and right directions through the moving device on the working table. In this way, the two workpieces 7 can be welded together. In addition, the air is transported to the nozzle 3 through the air supply mechanism 5, and the nozzle 3 then discharges the air upward. After the discharged air acts on the bottom of the welding position of the two workpieces 7, it flows toward the left and right sides in the strip groove 2. Because the temperature of the welding position of the two workpieces 7 is higher than the temperature of the welded and unwelded positions, the heat of the welding position of the two workpieces 7 can be transferred to the welded and unwelded positions of the two workpieces 7 through the flow of air, thereby reducing the temperature difference between the welded, unwelded and welding positions of the two workpieces 7, improving the uniformity of the temperature on the workpiece 7, reducing the stress caused by thermal expansion and contraction, reducing the deformation of the copper busbar, and thus improving the welding accuracy;

[0026] During welding, the nozzle 3 and the base 1 are moved in opposite directions by the translation module mechanism 4, so that the nozzle 3 and the welding device on the welding machine can maintain a relatively static and facing position relationship, that is, the discharge of the nozzle 3 can act on the positive welding point of the two workpieces 7.

[0027] After welding is completed, the clamping mechanism 6 releases the workpiece 7 and takes the workpiece 7 out. At this time, the device is in a standby state and can continue to weld the workpiece 7.

[0028] The air supply mechanism 5 includes an air pipe 51 vertically penetrated on the base 1, the top of the air pipe 51 is located in the strip groove 2, an air pump 52 is fixedly arranged at the bottom of the base 1, the air pipe 51 is installed on the air pump 52, a connecting pipe 53 is arranged between the air pipe 51 and the nozzle 3, the two ends of the connecting pipe 53 are respectively connected with the air pipe 51 and the nozzle 3, and the connecting pipe 53 is a hose;

[0029] The air pump 52 is started to transport air from the bottom end of the air pipe 51 to the inside of the air pipe 51, and the air inside the air pipe 51 is then transported from the top end of the air pipe 51 to the connecting pipe 53, and the air in the connecting pipe 53 is then transported to the nozzle 3, and the nozzle 3 then discharges the air upward.

[0030] The translation module mechanism includes a first lead screw 41, the first lead screw 41 is parallel to the left and right direction, one end of the first lead screw 41 is driven by a motor 42, the housing of the motor 42 is fixedly connected to the inner wall of the strip groove 2, and a first slider 43 is threadedly connected to the first lead screw 41, and the first slider 43 is fixedly connected to the nozzle 3;

[0031] The motor 42 is started to rotate the first lead screw 41 . The rotation of the first lead screw 41 causes the first slider 43 to move on the first lead screw 41 . The movement of the first slider 43 drives the nozzle 3 to move synchronously.

[0032] The clamping mechanism 6 includes a slide groove 61 arranged at the top of the base 1, and a second screw 62 is arranged in the slide groove 61, and the second screw 62 and the slide groove 61 are parallel to the front and rear directions, and the second screw 62 is connected to the inner wall of the slide groove 61 through a bearing 63, and a rocking wheel 64 is installed on the second screw 62, and the rocking wheel 64 is located at the end of the second screw 62 away from the strip groove 2, and the rocking wheel 64 screw is located outside the slide groove 61, and a second slider 65 is threadedly connected to the second screw 62, and the bottom of the second slider 65 is sealed with the bottom of the slide groove 61, and the left and right sides of the second slider 65 are respectively sealed with the inner walls of the left and right sides of the slide groove 61, and a clamping plate 66 is fixedly arranged on one side of the second slider 65 close to the strip groove 2, and the clamping plate 66 is located above the base 1, and the clamping plate 66 is in contact with the top of the base 1, and the second slider 65 and the clamping plate 66 are an integrally formed structure;

[0033] Rotating the rocker 64 causes the second lead screw 62 to rotate on the bearing 63, which can then cause the second slider 65 to move back and forth on the second lead screw 62. The movement of the second slider 65 drives the clamping plate 66 to move synchronously, so that the two clamping plates 66 can clamp or release the workpiece 7. The cooperation between the second slider 65 and the slide groove 61 can not only prevent the air in the strip groove 2 from being discharged from the slide groove 61, but also play the role of guiding the movement of the second slider 65.

[0034] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
