[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 shown, a tooling disassembly device includes a disassembly tooling. The disassembly tooling is provided with a positioning post 8 for positioning the welding tooling 1. A positioning hole 12 is provided at the position corresponding to the positioning post 8 on the welding tooling 1;

[0023] The welding tooling 1 fixes the PCB board 2 through pressure-blocks. At the position corresponding to the pressure-blocks on the disassembly tooling, there is a support block 9 that fits with the pressure-blocks. During the downward pressing process of the welding tooling 1, the pressure-blocks are in contact with the head inclined surface of the support block 9 in the disassembly tooling and are stressed, and then shrink and move backward to release the PCB board 2. When the welding tooling 1 is not pressed downward, the pressure-blocks clamp the PCB board 2, and are supported and release the PCB board 2 during the downward pressing process, realizing rapid disassembly.

[0024] As Figure 1 、 4 As shown in FIGS. 4 and 5, the pressure-blocks adopt a spring movable structure that can contract and move back and forth. Under the action of the spring, they clamp the PCB board 2 forward. An inclined block is provided at the bottom of the pressure-block, which fits with the head inclined surface of the support block 9 and shrinks and moves backward under the action of the support block 9 to release the PCB board 2.

[0025] The pressure-blocks include a first pressure-block 4, a second pressure-block 5, a third pressure-block 6, and a fourth pressure-block 7 symmetrically arranged along the center line of the PCB board 2. The first pressure-block 4 and the second pressure-block 5 are arranged side by side on one side of the PCB board 2, and the third pressure-block 6 and the fourth pressure-block 7 are arranged on the opposite side of the PCB board 2.

[0026] As Figure 1 and 3 shown, the disassembly tooling includes a bottom plate 11. Support blocks 9 are provided at the positions corresponding to the first pressure-block 4, the second pressure-block 5, the third pressure-block 6, and the fourth pressure-block 7 on the bottom plate 11. During the downward pressing process of the welding tooling 1, the support blocks 9 are in contact with and push the first pressure-block 4, the second pressure-block 5, the third pressure-block 6, and the fourth pressure-block 7 to shrink and move backward. AsFigure 4 As shown, through the inclined block at the bottom of the pressure block, Figure 3 The inclined surfaces at the tops of the pressure blocks 1 4 , 2 5 , 3 6 and 4 7 shown in the figure cooperate to enable the pressure blocks 1 4 , 2 5 , 3 6 and 4 7 to move away from the PCB board 2 , thereby releasing the PCB board 2 .

[0027] like Figure 1 , 2 As shown in Figures 3 and 4, positioning posts 8 are provided at the four corners of the bottom plate 11, and positioning holes 12 are provided at the four corresponding positioning posts 8 on the welding fixture 1, so that the welding fixture 1 can move up and down in a horizontal state along the positioning posts 8 through the positioning holes 12. The purpose of the positioning holes 12 is to enable the welding fixture 1 to move downward in a horizontal state, so as to ensure that during the process of pressing down the welding fixture 1, one side of the welding fixture 1 is not higher than the other side, and multiple blocking blocks cannot be released at the same time, or even rollover occurs.

[0028] like Figure 1 , 2 As shown in Figures 3 and 4, a limiting mechanism that fits the outer contour of the welding tool 1 is provided on the disassembly tool, and the limiting mechanism is used to limit the translation of the welding tool 1 relative to the disassembly tool. The limiting mechanism includes four fixing plates 10, which are arranged at the four corners of the disassembly tool, and the fixing plates 10 are respectively fitted with the four corners or four sides of the welding tool 1. The fixing plate 10 is an L-shaped plate, which wraps the four corners of the welding tool 1, can play a positioning role more quickly, and prevent the welding tool 1 from sliding horizontally during the pressing process, that is, sliding forward, backward, left and right.

[0029] like Figure 1 , 4 As shown in , 5, a cover plate 3 is provided on the welding tool 1, and the cover plate 3 fixes the PCB board 2 by flipping.

[0030] First, after the previous process of the PCB board product in the air conditioner electrical components is completed, the electrical module diodes, IPM, IGBT, etc. on it need to be welded, and then the next process is carried out. The PCB board 2 after the previous process patch and plug-in are manually placed in the welding tool 1, assembled and locked, and then placed together in the factory welding equipment, waiting for the welding process to be completed. When the welding equipment completes all welding processes, the welding tool 1 carrying the PCB board 2 is then transferred to the placement area of ​​the next process through the workshop assembly line, ready for the next disassembly process, and the tool disassembly device of the utility model can be used at this time.

[0031] First step, manually take the material from the pipeline placement area, take out the soldering tooling 1 carrying the PCB board 2, and place it into this tooling disassembly device. The soldering tooling 1 is placed flat on the disassembly tooling, and its outer contour fits with the four fixing plates 10 on the disassembly tooling. Moreover, the four positioning posts 8 of the disassembly tooling are inserted into the four round holes on the soldering tooling 1, so that there is no shaking in the front-back direction through positioning.

[0032] Second step, manually press down the soldering tooling 1 gently by hand to make it move downward. At this time, the pressure-block on the soldering tooling 1 will fit with the head inclined surface of the support block 9 in the disassembly tooling. The pressure-block on the soldering tooling 1 is spring-actuated and can contract and move back and forth. After being stressed and fitting with the support block 9, it will contract and move backward. After all four pressure-blocks contract and move, at this time the PCB board 2 is released, and the operator can take out the completed PCB board 2, and finally recycle the soldering tooling 1.

[0033] This utility model is made and assembled by using positioning posts 8, fixing plates 10, limit blocks, support blocks 9, etc. After placing the soldering tooling 1 on it, through the rapid pressing-down method, accurate positioning and automatic disassembly of the PCB board 2, as well as rapid picking and placing, are realized. Compared with the previous manual operation mode, this invention device greatly reduces the labor intensity of employees, has stable operation, more guarantees the quality in the production process, and improves the overall production efficiency.

[0034] The efficiency of the original operation mode by hand is relatively low. When disassembling a single PCB board product, the operator needs to use multiple fingers and operate four times until the PCB board 2 is taken out. The time used for a single product is about 8 seconds. After developing this device, through the rapid pressing-down method, the PCB board 2 is automatically disassembled, picked and placed quickly. The time used for a single product is about 4 seconds, and the disassembly process is stable without scratching or squeezing the PCB board 2. Comparing the two effects, the overall efficiency of this invention device is increased by about 50%. Calculated according to the daily output, the output of the original operation mode in a single shift of 8 hours is about 2,800 pieces. After using this device, the single-shift output is expected to reach about 4,200 pieces, and the benefit is significantly improved.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
