Please refer to the figure in the eighth figure, which is a sectional view of the conventional fixing seat. It is clear that the hollow interior of the fixing base A has a screw hole A1, and a positioning post A2 welded in the hole of the fixing plate body is disposed at the bottom of the screw hole A1, and the top surface of the fixing base A is attached. With the film B, the suction film on the suction device (such as a vacuum suction cup or a suction device) can be used to pick up the film B of the fixing seat A, and the fixing seat A can be moved to the fixed plate body by the suction head. At the upper hole, it is released into the fixed seat A, so that the positioning post A2 penetrates into the hole for subsequent welding operation, so that the positioning post A2 of the fixing seat A can be firmly welded in the hole of the fixed plate body and integrated into one. However, the fixing block A is covered with the film B, and the film B needs to be closely attached to ensure the surface is flat. If there is a little bubble between the film B and the fixing seat A, it will cause suction. The head cannot be closely adsorbed, or the offset or drop of the fixed seat A is likely to occur during the process of moving the alignment. It is difficult to ensure the quality and yield of the welding, which not only causes a significant increase in the required labor and cost, but also The film B can not be reused, which is not conducive to the increase of production capacity. It is to be engaged in this industry, it re-designed to be effectively addressed.

Therefore, the new creators have designed and developed such fixed seats by collecting and researching related materials through multi-party evaluation and consideration, and using the years of R&D experience in this industry to continuously try and modify. A new type of casing for adsorption.

The main purpose of the present invention is to form a screw hole at the inner wall surface of the hollow spacer column of the fixed seat, and a positioning portion is arranged at the bottom of the spacer column, so that the sleeve body can be sleeved from the top to the bottom on the fixing seat. The spacer column is pushed into the socket space through the opening below the sleeve to form a pressing position, and the positioning portion of the fixing seat is exposed at the opening, and then the suction head is adsorbed on the adsorption surface of the sleeve body for taking. And the belt is moved to the hole of the first plate body, and the positioning portion of the fixing seat is inserted into the hole by the suction head being released into the sleeve, and the sleeve is sleeved on the sleeve The fixing seat can keep the overall center of gravity stable, so that the positioning portion of the fixing seat and the hole of the first plate body can be more accurately aligned, thereby achieving structural stability, improving welding quality and yield, and reducing cost.

The secondary purpose of this creation is that the casing is integrally formed by a plastic injection molding. Since the casing may cause protrusions at the center of the adsorption surface after injection molding, so that the adsorption surface is difficult to maintain flatness and manufacturing difficulties, the utility model can be utilized. The concave portion formed at the center of the casing adsorption surface removes the convex portion, and ensures that the suction head can be closely adhered to the adsorption surface of the casing to take the fixing seat to pick up, so as to avoid the inability of the suction head to be closely adsorbed. It is easy to cause an offset or drop in the process of moving the alignment.

Another purpose of the creation is that after the fixing seat and the first plate body are welded, if the sleeve body is to be disassembled, it is only necessary to hold the pulling portion outside the sleeve body to pull up, and the spacing of the fixing seat is The column is separated from the socket space of the casing to form a separated state, and the casing can be quickly disassembled and less laborious, and the casing can be reused many times after being disassembled, thereby effectively saving costs.

Please refer to the first, second, third and fourth figures, which are respectively the three-dimensional appearance drawing, the three-dimensional exploded view, the three-dimensional exploded view and the sectional view of another perspective. It can be clearly seen from the figure that the creation is The fixing base 1 and the sleeve body 2 are included, wherein the fixing base 1 has a hollow spacer 11 and a screw hole 12 is formed at the inner wall surface of the spacer post 11 , and the bottom of the spacer post 11 is located at the outer periphery of the screw hole 12 . A positioning portion 13 is disposed on the positioning portion 13 and has a positioning post 131 having a smaller outer diameter than the spacer post 11 , and a positioning surface 132 is formed on the lateral surface of the positioning post 131 adjacent to the spacer post 11 .

The sleeve body 2 is formed with a socket space 20, and an outwardly expanding opening 201 is formed below the socket space 20, and the top of the sleeve body 2 has a flat adsorption surface 21 for adsorption. A concave portion 211 is formed in the center of the surface 21, and a convex annular portion 22 is disposed adjacent to the adsorption surface 21 at the outer portion of the sleeve 2.

Please refer to the fifth, sixth and seventh figures, which are respectively a cross-sectional view of the preferred embodiment of the present invention, a cross-sectional view of the preferred embodiment after welding, and a cross-sectional view of another preferred embodiment. It can be clearly seen that when the present invention is assembled, the sleeve 2 is firstly sleeved up and down on the spacer post 11 of the fixing base 1, and the spacer column 11 passes through the opening 201 below the casing 2. Pushed into the socket space 20, and because the sleeve body 2 is made of heat-resistant silicone material, And the inner diameter of the sleeve 2 is smaller than the outer diameter of the spacer column 11, thereby providing the spacer column 11 to be pushed in along the inner wall surface of the sleeve space 20 of the sleeve body 2, so that the sleeve body 2 can be supported outward. The force is deformed and the inner diameter becomes large, and the spacer 2 is pushed into the positioning position, and the sleeve 2 is sleeved on the spacer post 11 of the fixing base 1 to form a pressing position, and the positioning of the fixing seat 1 is performed.

Difficult to manufacture, when the suction head 3 is adsorbed, it will not be closely adsorbed on the adsorption surface 21 of the casing 2, and the casing 2 will be easily offset or dropped during the process of moving the fixed seat 1 in position. The situation occurs, so that the convex portion can be removed by the concave portion 211 formed by mechanical processing (such as cutting, trenching, etc.) at the center of the adsorption surface 21 of the casing 2, and the suction head 3 can be closely adhered to the sleeve. The fixing seat 1 is taken up on the adsorption surface 21 of the body 2.

After the fixing of the fixing base 1 and the first plate body 4, if the user wants to disassemble the casing 2, only the pulling portion 22 of the casing 2 is required to be pulled up and the spacing of the fixing base 1 is separated. The sleeve 11 is separated from the socket space 20 of the sleeve body 2 to form a separated state, so that the sleeve body 2 can be quickly disassembled and less laborious, and has the effect of easy operation, and the sleeve body 2 can be repeatedly repeated after being disassembled. Use to save costs.

In addition, the second plate body 5 can be further combined at the upper portion of the spacer post 11 of the fixing base 1, and the bottom surface of the second plate body 5 is abutted against the top of the fixing base 1, and the through hole 51 corresponds to the fixing seat. The screw 522 of the positioning member 52 passes through the through hole 51 of the second plate body 5, and then locks into the screw hole 12 of the fixing base 1 and is rotated by the positioning member 52. The head end 521 is abutted against the periphery of the through hole 51, and the second plate body 5 and the fixing base 1 are locked and fixed integrally, so that the spacer post 11 of the fixing base 1 can be inserted through the spacer. A predetermined distance is formed between the second plate body 5 and the first plate body 4 to avoid short circuit or contact caused by the plurality of electronic components (not shown) on the second plate body 5 contacting the first plate body 4. Bad conditions occur and the overall structure is more stable.
