DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a high-precision spot welding device for single-chip microcomputer production, such as Figure 1-5As shown, the electric welding device includes an operating table 1, a carrier frame 11 fixedly mounted on the operating table 1, and a spot welding machine 12 arranged on the carrier frame 11, the operating table 1 is symmetrically provided with two slide rails 13, a drive box 2 is slidably mounted on the slide rails 13, a placement table 21 is fixedly mounted on one end of the drive box 2 away from the operating table 1, four guide grooves 211 distributed in a circular array are opened on the placement table 21, a guide block 41 is slidably mounted in the guide groove 211, and a clamping plate 4 is fixedly mounted on the guide block 41; a transmission gear 42 is rotatably mounted in the drive box 2 through a rotating shaft, a connecting rod 43 is fixedly mounted on the transmission gear 42, a driving arm 44 is fixedly mounted on one end of the connecting rod 43 away from the transmission gear 42, four connecting rods 45 distributed in a circular array are rotatably mounted on the driving arm 44, and one end of the connecting rod 45 away from the driving arm 44 is rotatably connected to the guide block 41, and a driving mechanism 3 meshing with the transmission gear 42 is arranged in the drive box 2.

[0025] When in use, the operator only needs to place the single chip microcomputer in the middle position of the placement table 21, start the driving mechanism 3, the driving mechanism 3 drives the transmission gear 42 meshing therewith to rotate, the transmission gear 42 drives the driving arm 44 fixedly connected thereto through the connecting rod 43 to rotate, when the driving arm 44 rotates, it will pull the connecting rod 45 to move, and the other end of the connecting rod 45 is fixed on the guide block 41, which will pull the guide block 41 to move along the guide groove 211, and the "T"-shaped guide block 41 is set in the "T"-shaped guide groove 211 and penetrates The placement table 21, one end of the guide block 41 is connected to the clamping plate 4, and the other end is rotatably connected to the connecting rod 45 set in the driving box 2. When the guide block 41 moves, it drives the four clamping plates 4 to converge toward the center, so as to clamp the single-chip microcomputer. The operation is very simple. Because the single-chip microcomputer itself has a small weight, only two parallel clamping plates 4 are needed to clamp the single-chip microcomputer to meet the need for fixing it. The above-mentioned device can ensure that there are at least two parallel clamping plates 4 to clamp the single-chip microcomputer when processing single-chip microcomputers of different sizes and placed in different directions.

[0026] Specifically, the driving mechanism 3 includes a worm 31 rotatably installed in the driving box 2 through a bracket, a driven bevel gear 32 fixedly installed at one end of the worm 31, and a driving motor 34 fixedly installed in the driving box 2, the output end of the driving motor 34 is provided with a fixed disk 332, and the output end of the driving motor 34 is slidably provided with an active bevel gear 33 meshing with the driven bevel gear 32; when the driving motor 34 is turned on, it drives the fixed disk 332, the active bevel gear 33, the driven bevel gear 32 and the worm 31 to rotate to realize power output, and at the same time, the worm 31 is meshed with the transmission gear 42 to achieve a self-locking effect on the splint 4, and the rotation can only be transmitted to the splint 4 by the driving motor 34, while self-locking will occur when the kinetic energy is transmitted in the reverse direction.

[0027] Furthermore, a limiting spring 331 is installed between the fixed plate 332 and the active bevel gear 33; when the driving motor 34 rotates, the limiting spring 331 realizes a pushing effect on the active bevel gear 33, thereby ensuring the meshing of the active bevel gear 33 and the driven bevel gear 32. When the active bevel gear 33 encounters a large resistance when driving the driven bevel gear 32, the active bevel gear 33 will slide back toward the driving motor 34 and compress the limiting spring 331, thereby interrupting the power transmission. When the required force is less than the elastic force of the limiting spring 331, the power transmission is restored, so that after the single-chip microcomputer is clamped, the clamping plate 4 will not continue to be tightened due to the rotation of the driving motor 34, thereby causing damage to the single-chip microcomputer.

[0028] Furthermore, a groove 212 is provided on the placing table 21, and an elastic mechanism 5 is provided in the groove 212. The elastic mechanism 5 includes a rotating shaft 52 rotatably installed in the groove 212, a rotating rod 51 sleeved on the rotating shaft 52, and a spring 53 provided between the groove 212 and the rotating rod 51. A first button 22 adapted to the driving motor 34 is provided on the driving box 2, and a second button 54 adapted to the driving motor 34 is provided in the groove 212; the spring 53 is not subjected to force. In this state, the rotating rod 51 can be lifted up, so as to achieve the effect of lifting up the single-chip computer when it is not clamped, thereby avoiding the problem of inconvenience in taking due to the single-chip computer being too thin. When starting the drive motor 34, it can be controlled by the first button 22. When placing the single-chip computer, the elastic mechanism 5 is pressed into the groove 212, and the second button 54 is further squeezed to start the drive motor 34 to start clamping, thereby simplifying the operation process. The working principles and connection methods of the first button 22, the second button 54 and the drive motor 34 are all existing mature technologies and will not be elaborated on here.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
