[0022] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. Specific parts in a particular drawing may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0023] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0024] A clamping mechanism of a grounding plate pressing fixture, including a base 1. A placement seat 2 is fixedly installed at the top end of the base 1, and a mounting plate 411 is connected to the top end of the base 1. A cylinder 4 is fixedly installed on the outer surface of the mounting plate 411, and a clamping plate 5 is connected to one end of the cylinder 4. Limiting rods 6 are connected to both sides of the clamping plate 5, and the limiting rods 6 are fixedly installed between the placement seat 2 and the cylinder 4. A cavity is formed inside the placement seat 2, and multiple groups of air pipes 913 are fixedly installed in the cavity. A diversion pipe 917 is connected between the multiple groups of air pipes 913, and a first drainage pipe 918, a second drainage pipe 919, and a third drainage pipe 920 are connected between the diversion pipes 917. One end of the first drainage pipe 918, the second drainage pipe 919, and the third drainage pipe 920 is connected to a connecting pipe 912, and one end of the connecting pipe 912 is connected to a vacuum pump 7. The vacuum pump 7 is fixedly installed on the outer surface of one side of the base 1. A top plate 3 is fixedly installed on the outer surface of the top end of the placement seat 2, and multiple groups of circular through holes are formed on the outer surface of the top plate 3. The multiple groups of circular through holes are parallel to the multiple groups of air pipes 913.

[0025] Furthermore, multiple groups of support seats 111 are fixedly installed on the outer surface of the bottom end of the base 1, and rubber is wrapped on the outer surface of the multiple groups of support seats 111. The support seats 111 ensure the overall stability of the fixture, enabling it to remain stable during the pressing process and not easily shake. The rubber wrapping reduces the friction between the fixture and the ground, preventing sliding, and also plays a certain shock-absorbing role, protecting the fixture and the ground.

[0026] Furthermore, a regulating valve 911 is provided on the outer surface of the connecting pipe 912. The regulating valve 911 allows the operator to adjust the suction force generated by the vacuum pump according to needs to adapt to grounding plates of different materials and sizes. And by precisely adjusting the suction force, the grounding plate can be fixed more quickly, improving the pressing efficiency.

[0027] Furthermore, a filter plate 914 is fixedly installed on the outer surface of the top ends of the multiple groups of air pipes 913. The filter plate 914 can filter out impurities in the airflow, preventing impurities from entering the air pipes, thereby extending the service life of the air pipes.

[0028] Further, multiple fixing rings 915 are fixedly installed on the outer surfaces of the first drainage tube 918, the second drainage tube 919, and the third drainage tube 920. A fixing rod 916 is fixedly installed on the outer surface of the fixing ring 915, and the fixing rod 916 is fixedly connected to the inner wall of the storage seat 2. The combination of the fixing ring 915 and the fixing rod 916 ensures the stability of the drainage tube and prevents its shaking and displacement during operation.

[0029] Further, fixing plates 8 are fixedly installed on both sides of the vacuum pump 7, and the fixing plates 8 are fixedly connected to the base 1 through bolts 9. The combination of the fixing plates 8 and the bolts 9 ensures the stable connection between the vacuum pump 7 and the base 1, prevents its loosening during operation, and can be easily disassembled and replaced, improving the maintainability of the fixture.

[0030] Further, the outer end of the top plate 3 is arc-shaped, and the outer surface of the top of the top plate 3 is wrapped with rubber. The arc-shaped design reduces the sharp edges of the top plate 3 and reduces the risk of injury to the operator. The rubber wrapping reduces the friction between the grounding plate and the top plate 3 and prevents the grounding plate from being scratched or damaged during the adsorption process.

[0031] Working principle: First, the grounding plate needs to be placed on the top plate 3 at the top of the storage seat 2. Multiple circular through grooves formed on the surface of the top plate 3 correspond to multiple air pipes 913 inside the storage seat 2 to ensure that the air flow can pass through smoothly. After the grounding plate is placed, the vacuum pump 7 is started. The vacuum pump 7 starts to work and generates a negative pressure air flow. This air flow first enters the first drainage tube 918, the second drainage tube 919, and the third drainage tube 920 through the connecting tube 912. Subsequently, these drainage tubes evenly distribute the air flow to the diversion tube 917 and finally transfer it to the air pipe 913. Since the air pipe 913 is located in the cavity of the storage seat 2 and is connected to the outside through the circular through groove of the top plate 3, when a negative pressure is generated in the air pipe 913, a suction force will be formed at the circular through groove. This suction force can firmly adsorb the grounding plate on the top plate 3 and ensure that the grounding plate will not move or shift during subsequent operations. After the grounding plate is adsorbed and fixed, the cylinder 4 is started. The cylinder 4 pushes the clamping plate 5 downward until the grounding plate is clamped between the clamping plate 5 and the top plate 3. On both sides of the clamping plate 5, limiting rods 6 are used to ensure the stability and accuracy of the clamping plate 5 during movement.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive.
