The principle of the utility model is that the screws are transported by a vibration plate 1, and then received by a receiving unit 3 and pushed to a picking position. After the screws are in place, the magnetic unit 7 absorbs the screws and places the screws in the threaded holes of the copper parts. After the screws are placed in the threaded holes of the copper parts, the screws are tightened in the threaded holes by a screwing unit 8. Compared with the prior art, this method has better flexibility of use and simplifies the conveying structure of the screws. That is, the vibration plate 1 can be used to meet the feeding requirements, which also reduces the complexity of the equipment.
[0021] The receiving unit 3 includes a third support seat 31, a side assembly block 32, and a slider 33 with a power source. The side assembly block 32 is assembled on the third support seat 31 and together forms a sliding cavity 34 for the slider 33 to slide in. The side assembly block 32 is provided with a guide channel 32-a that is interconnected with the conveying track of the vibration plate 1 and used to guide the screw. The slider 33 is provided with a positioning node 33-a that is interconnected with the guide channel 32-a and used to confirm the final position of the screw in the slider 33. The third support seat 31 provides a use height so that the feed port of the guide channel 32-a of the side assembly block 32 is aligned with the conveying track of the vibration plate 1. The discharge port of the feeding track is maintained at the same horizontal height, which is convenient for guiding the screw to pass through the wire channel 32-a into the positioning node 33-a, that is, placed in the slider 33. The third support seat 31 and the side assembly block 32 are assembled to increase the scope of application. The side assembly block 32 and the slider 33 can be replaced according to the size of the screw being transported, that is, the guide channel 32-a and the positioning node 33-a meet the size requirements of the screw. The sliding cavity 34 not only provides a space for the slider 33 to be placed inside, but also defines the movement guide of the slider 33, so that the slider 33 can use sliding to send the screw to the picking position.
[0022] A constraint cover 9 for upper constraint on the screw is provided at the upper end of the third supporting seat 31. The constraint cover 9 enables the slider 33 and the side assembly block 32 to have the same upper constraint function as the conveying track of the vibration plate 1, so that the screw will not fall forward when moving in the guide channel 32-a or the positioning node 33-a, thereby ensuring the success rate of screw delivery.
[0023] A support block 31-a is arranged on the front end surface of the third support seat 31, and a first cylinder 10 as a power source is arranged at the front end of the support block 31-a.

The transverse portion is used to provide a use length that satisfies the first cylinder 10, the slider connector 101 and the slider 33 partially exposed outside the sliding cavity 34. In this way, the first cylinder 10 can obtain good bottom support and exhibit good stability when in use. The slider connector 101 is used to compensate for the problem of small connection area provided when the piston rod of the first cylinder 10 is directly connected to the slider 33, thereby increasing the stability and smoothness of the slider 33 when moving.
[0024] The slider connector 101 is provided with a socket 101-a, and the slider 33 is provided with an insert block 33-b inserted into the socket 101-a. This method facilitates the connection between the slider connector 101 and the slider 33, that is, the slider 33 can be inserted into the socket 101-a using the insert block 33-b, which is easy to operate.
[0025] The magnetic unit 7 includes a fixed seat 71 arranged on a slide rail slider structure, and a movable arm 72 and a second cylinder 73 respectively arranged on both sides of the fixed seat 71. A vacuum suction head 20 is arranged at the end of the movable arm 72. The second cylinder 73 is used to drive the movable arm 72 to move. The slide rail slider structure enables the magnetic unit 7 to have the ability to move horizontally. The fixed seat 71 provides a slideway to enable the magnetic unit 7 to have the ability to move vertically. The vacuum washing head 20 is used to absorb the screws. This has better flexibility in use, and can quickly and accurately remove the screws and insert the screws into the threaded holes of the copper parts.
[0026] The screwing unit 8 includes a movable frame 81 and a motor 82 arranged on the movable frame 81. The movable frame 81 is moved by a slide rail slider structure arranged on the screwing connector 6. The screwing connector 6 is provided with a third cylinder 61 for driving the movable frame 81 to move. A screwing tool 30 for screwing is connected to the output end of the motor 82. The slide rail slider structure enables the screwing unit 8 to have vertical movement capability. The motor 82 is used to connect with the screwing tool 30 and enable the screwing tool 30 to rotate, thereby realizing the screwing action of the screw.
[0027] A positioning plate 62 is provided at the bottom of the wire tightening connector 6 and is perpendicular to the extension direction of the wire tightening tool 30. The positioning plate 62 is provided with a socket 62-a for the wire tightening tool 30 to pass through and covers part of the wire tightening tool 30. The positioning plate 62 plays an auxiliary role, that is, providing the socket 62-a for the wire tightening tool 30 to pass through, and the inner circumference of the socket 62-a can fit with the outer circumference of the wire tightening tool 30, thereby improving the stability of the wire tightening tool 30 during operation, that is, reducing jitter, thereby improving the wire tightening efficiency and effect.
