[0030] It should be noted that work unit 2 can be an electric screwdriver or a compression device with a pneumatic cylinder, when work unit 2 is an electric screwdriver, the electric screwdriver head is located in the containing cavity 110, and the electric screwdriver head moves downward to the machining cavity and abuts against the corresponding machining part during use, and the electric screwdriver head rotates to drive the corresponding machining part to the corresponding position.Similarly, when work unit 2 is a compression device with a pneumatic cylinder, the output end of the compression device is located in the containing cavity 110, and the output end moves downward to the machining cavity and abuts against the corresponding machining part during use, and the output end drives the machining part to embed in the corresponding position.

[0031] Further, the vacuum adsorption device further comprises a fixing mechanism 8, the vacuum adsorption mechanism 1 is fixedly installed on the fixing mechanism, and the working unit 2 is movably installed on the fixing mechanism. In the embodiment, the fixing mechanism comprises a fixing support 81 and a first mounting bracket 82 and a second mounting bracket 88 installed on the fixing support 81, wherein the first mounting bracket 82 is fixedly connected with the working unit 2, and the second mounting bracket 88 is fixedly connected with the vacuum adsorption mechanism 1. The first mounting bracket 82 moves on the fixing support 81, thereby driving the working unit 2 to move, so that the working unit 2 can adjust its position according to the use condition; similarly, the second mounting bracket 88 moves on the fixing support 81, thereby driving the vacuum adsorption mechanism 1 to move, so that the vacuum adsorption mechanism 1 can adjust its position according to the use condition and cooperate with the working unit 2.

[0032] Further, the accommodating cavity 110 comprises a moving cavity 1101 and a working cavity 1102, and a slope 1103 is formed at the connection of the moving cavity 1101 and the working cavity 1102; the moving cavity 1101 is in communication with the working cavity 1102, the working cavity 1102 is in communication with the outside, and the moving cavity 1101 is in communication with the outside based on the working cavity 1102, that is, the accommodating cavity 110 is in communication with the outside. The slope 1103 has a clear guiding property, so that the working unit 2 can accurately enter the working cavity 1102, and this is beneficial to the accurate machining of the working unit 2. The moving cavity 1101 is used for accommodating the output end of the corresponding working unit 2, so as to reduce the risk of deformation of the output end of the working unit 2 due to collision with the outside during use, and the working cavity 1102 is used for aligning and connecting the output end of the working unit 2 with the corresponding machining part, so as to ensure that the gap and the fit degree between the parts meet the working requirements.

[0033] Further, the moving cavity 1101 is in communication with a plurality of air suction ports 111. In the embodiment, the moving cavity 1101 is in communication with two air suction ports 111, and the two air suction ports 111 are located at opposite sides, each of the air suction ports 111 is provided with an air pipe, and the other end of the air pipe is connected with an air suction device. When the air suction device starts to work, simultaneously suctioning air from two directions can significantly accelerate the air flow speed in the accommodating cavity 110, thereby shortening the time required to reach the required negative pressure state. Simultaneously suctioning air from two directions can ensure that the negative pressure in the accommodating cavity 110 is more uniform, avoiding the situation that the negative pressure is insufficient or excessive in some areas, and this is beneficial to ensuring that the environmental conditions in the whole accommodating cavity 110 are more consistent and stable.

[0034] Specifically, the vacuum suction device moves to the corresponding material area, the processing parts in the material area are attracted into the limiting groove 112, and then the two air suction ports 111 work simultaneously to extract the gas in the containing cavity 110, so that a negative pressure state is formed in the containing cavity 110. Atmospheric pressure has a force on the processing parts, so that the processing parts are adsorbed in the limiting groove 112, reducing the risk of falling of the processing parts. Then the vacuum suction device moves to the corresponding processing position, the two air suction ports 111 stop suction, the output end of the processing unit moves in the containing cavity 110 towards the limiting groove 112 until abutting with the processing parts, and pushes the processing parts away from the limiting groove 112 and installs to the corresponding position. In this process, air enters the containing cavity 110 from the gap between the limiting groove 112 and the processing parts, so that the air pressure in the containing cavity 110 becomes normal atmospheric pressure, reducing the force of atmospheric pressure on the processing parts, which is beneficial to reduce the energy consumption of the processing unit.

[0035] Further, the vacuum suction mechanism 1 further comprises a connecting seat 3, the connecting seat 3 has a connecting hole 31; the working unit 2 passes through the connecting seat 3 based on the connecting hole 31, and the connecting part of the working unit 2 and the connecting seat 3 is provided with a first sealing layer 4 and a second sealing layer 5. The first sealing layer 4 is arranged on the contact surface of the connecting seat 3 and the working unit 2, and its main function is to fill the small gap between the two and prevent gas leakage. The second sealing layer 5 is arranged outside the first sealing layer 4, and its main function is to provide additional protection to prevent the first sealing layer 4 from failing due to long-term use or wear. Double sealing significantly improves the overall sealing performance and reduces the risk of gas exchange between the containing cavity 110 and the outside.

[0036] Further, the inner wall of the first sealing layer 4 abuts against the working unit 2, and the outer wall of the second sealing layer 5 abuts against the connecting seat 3. The first sealing layer 4 is used to seal the gap between the working unit 2 and the connecting seat 3, so as to avoid gas flowing out of the gap between the working unit 2 and the connecting seat 3 during use, which is beneficial to maintain the negative pressure state in the containing cavity 110 and adsorb the processing parts in the limiting groove 112. The second sealing layer 5 is used to seal the gap between the connecting seat 3 and the containing cavity 110, so as to avoid gas flowing out of the gap between the working unit 2 and the connecting seat 3 during use, which is beneficial to maintain the negative pressure state in the containing cavity 110 and adsorb the processing parts in the limiting groove 112. The structure of the double sealing layer performs double sealing on the containing cavity 110, reduces the risk of leakage of the containing cavity 110, and is beneficial to stably adsorb the processing parts in the limiting groove 112.

[0037] Further, the connecting seat 3 and the base 11 are provided with a mounting seat 6 extending away from the base 11 to form a connecting part 7. The mounting seat 6 is used to connect the connecting seat 3 and the base 11, and the connecting part 7 is used to mount the vacuum adsorption device to the corresponding position, so that the vacuum adsorption device can be mounted on the corresponding equipment. The base 11, the mounting seat 6 and the connecting seat 3 form a clear hierarchical structure, so that the connection between each component is more stable, and maintenance and replacement are also facilitated.

[0038] Further, the connecting part 7 has a plurality of clamping bosses 71 and a plurality of fixing holes 72, and the plurality of clamping bosses 71 are distributed on both sides of the plurality of fixing holes 72. In this embodiment, the connecting part 7 has two clamping bosses 71 and two fixing holes 72, and the two clamping bosses 71 are symmetrically distributed on both sides of the two fixing holes 72. The clamping boss 71 is used to clamp the connecting part 7 on the corresponding device, and the fixing hole 72 is used to fix the connecting part 7 on the corresponding device. The clamping boss 71 is inserted into the clamping groove of the corresponding device, and the two are clamped together to form a stable mechanical connection, so that the connecting part 7 is more stable and reliable, which helps to reduce the risk of falling or circumferential rotation of the connecting part 7 during use. The fixing hole 72 fixes the connecting part 7 and the corresponding device together by connecting fasteners to provide stable mechanical support for the entire structure and reduce the risk of falling or circumferential rotation of the connecting part 7 during use.

[0039] Further, the root of the limiting groove 112 and the side wall of the limiting groove 112 are connected to form a curved surface. The curved surface design of the limiting groove 112 can provide a guiding effect, ensure that the processed parts always maintain the correct direction during sliding, and reduce wear caused by friction. The curved surface design helps to achieve a tighter fit during assembly. When the processed parts are inserted into the limiting groove 112, the curved surface can guide the components to gradually enter the correct position, thereby reducing assembly errors. Secondly, the limiting groove 112 has a magnet, which can have an adsorption effect on the processed parts, and can firmly adsorb these parts to avoid losing or falling of the processed parts during use, thereby reducing the time to find and pick up the parts again and improving work efficiency.

[0040] Need to explain, the limiting groove 112 with the accommodating cavity 110 is located in the same axis, the limiting groove 112 and the accommodating cavity 110 are located in the same axis, the output end of the working unit 2 is moved from the moving cavity 1101 to the machining cavity during processing, and is in abutment with the machining part from the machining cavity, pushes the machining part away from the limiting groove 112, helps to reduce the friction and vibration between the working unit 2 and the inner wall of the accommodating cavity 110.Secondly, the working unit 2 can more easily align and insert the parts into the correct position, thereby reducing the assembly time and error rate.

[0041] In summary, the utility model discloses a plurality of air inlets are set up, and a plurality of air inlets extract gas from different directions to the accommodating cavity, can provide a balanced airflow environment, reduce the risk of the formation of uneven airflow environment in the accommodating cavity, cause the partial air pressure in the accommodating cavity to be inconsistent, benefit the corresponding machining part is adsorbed in the limiting groove.
