DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-3 A diode welding buffer mechanism in this embodiment includes a welding tool 1, on which a welding table 2 and a welding pen 3 are provided, and a buffer structure and a fixing structure are provided on the welding table 2. The welding table 2 is fixedly installed on the top of the welding tool 1, and a bracket 5 for hanging the welding pen 3 is fixedly installed on the top of the welding tool 1. A control cabinet 6 is fixedly installed on the right side of the welding tool 1, and the welding pen 3 is suspended on the bracket 5.

[0022] In the present embodiment, the buffer structure includes a mounting frame 41 fixedly mounted on the top of the welding table 2, a support frame 42 for supporting the PCB circuit board is slidably mounted inside the mounting frame 41, a guide rod 43 is fixedly mounted inside the mounting frame 41, the mounting frame 41 includes a rectangular frame and two vertical plates, the two vertical plates are fixedly mounted on the inner bottom wall of the rectangular frame, the guide rod 43 is fixedly mounted between the opposite sides of the two vertical plates, the rectangular frame is fixedly mounted on the welding table 2, and it is convenient to support the fixed installation of the guide rod 43, a buffer member 44 is slidably mounted on the guide rod 43, and a telescopic spring 45 for buffering is sleeved on the outer surface of the guide rod 43 to buffer the rigid force, and a trapezoidal block 46 for extrusion and transmission force is fixedly mounted on the inner top wall of the support frame 42 to facilitate the conduction of the rigid force.

[0023] Among them, the buffer component 44 includes two buffer blocks, both of which are slidably installed on the outer surface of the guide rod 43, and the opposite sides of the two buffer blocks are fixedly connected to the left and right sides of the telescopic spring 45 respectively. The inclined surfaces of the two buffer blocks are respectively in contact with the inclined surfaces of the trapezoidal block 46, so that the trapezoidal block 46 can be used to squeeze the two buffer blocks, thereby pulling the telescopic spring 45 to achieve a buffering effect.

[0024] By adopting the above technical solution, the force of the soldering pen 3 on the PCB circuit board is transmitted to the trapezoidal block 46 through the support frame 42, so that the trapezoidal block 46 is used to move downward the two buffer blocks in the extrusion buffer 44, so that the two buffer blocks move to opposite sides, thereby stretching the telescopic spring 45 on the guide rod 43, thereby achieving the rigid force during the buffer diode welding process.

[0025] In the implementation of this example, the fixed structure includes a limit assembly 47 for limiting the upward and downward movement trajectory of the support frame 42. Two positioning plates 48 for clamping the PCB circuit board are slidably installed on the support frame 42. Four through grooves are opened on the top of the support frame 42. The left view of the two positioning plates 48 is concave in shape. The inner walls of the two through grooves on the same side are respectively slidably connected to the positioning plates 48 on the same side, which is convenient for the sliding of the positioning plates 48 and the clamping of the PCB circuit board. A feeding assembly 49 for controlling the left and right movement of the two positioning plates 48 is provided on the support frame 42. The feeding assembly 49 includes two electric push rods, which are respectively fixedly installed on the left and right sides of the support frame 42 and both penetrate into the interior of the support frame 42. The telescopic ends of the two electric push rods are respectively fixedly connected to the two positioning plates 48, which is convenient for controlling the two positioning plates 48 to move to the opposite side or the opposite side.

[0026] Among them, the limit assembly 47 includes a limit strip and a limit groove. The limit groove is opened on the rear side wall of the inner cavity of the installation frame 41. The limit strip is fixedly installed on the back of the support frame 42. The inner wall of the limit groove is slidably connected to the outer surface of the limit strip, so as to limit the support frame 42 to move up and down only inside the installation frame 41.

[0027] By adopting the above technical solution, the PCB circuit board is placed on the support frame 42, and the two electric push rods in the feed assembly 49 are started, so that the positioning plate 48 is driven to move by the extension and retraction of the electric push rods, thereby controlling the positioning plate 48 to clamp and fix the PCB circuit board.

[0028] The working principle of the above embodiment is:

[0029] When the diode welding buffer mechanism is in use, the PCB circuit board is placed on the support frame 42, and the two electric push rods in the feed assembly 49 are started, so that the positioning plate 48 is driven to move by the extension and retraction of the electric push rods, so as to control the positioning plate 48 to clamp and fix the PCB circuit board. When the diode is welded, the force of the welding pen 3 on the PCB circuit board is transmitted to the trapezoidal block 46 through the support frame 42, so that the trapezoidal block 46 is used to move downward to squeeze the two buffer blocks in the buffer member 44, so that the two buffer blocks move to opposite sides, thereby reaching the extension spring 45 on the guide rod 43, so as to achieve the rigid force of the buffer diode welding process.
