[0036] A plurality of slides are slidably arranged on the slide rail 14, the number of which is the same as that of the clamping jaws 2 11.

A return spring is fixedly arranged in the vertical wall of the lower chamber 24, and the end of the return spring is fixedly connected to the limit plate 26, which is used to drive the limit plate 26 to return to the side close to the slide tube 25. Specifically, when the limit plate 26 is plugged into the slide tube 25, the slide tube 25 is in a limited state and cooperates with the screw 22 in threaded transmission, and at the same time drives the slide seat 2 to move; after the limit plate 26 is separated from the slide tube 25, the slide tube 25 rotates with the screw 22, and the slide seat 2 stops moving.

[0038] Preferably, two groups of slide rails 14 are symmetrically arranged, and a lead screw 22 and a drive motor 3 for driving the lead screw 22 are respectively arranged in the two groups of slide rails 14. The two drive motors 3 are arranged in opposite directions, so that the stainless steel plate 2 can be moved in different directions to be used for splicing the stainless steel plate 1 in the opposite direction of the notch.

Preferably, the contact piece 31 is in the shape of a round tube, and the lead screw 22 is provided through the contact piece 31.

[0040] A lead screw 2 34 is rotatably provided at the top of the slide 2. A sliding member 35 that can move vertically is connected to the bottom of the clamp 2 11. The lead screw 2 34 penetrates the sliding member 35 and is threadedly coupled with the sliding member 35. The bottom end of the lead screw 2 34 extends into the upper chamber 23. A connecting plate 36 is fixedly connected to the side of the abutment member 31 away from the slide 2; and an abutment member 2 37 is slidably connected to the side of the sliding member 35 close to the connecting plate 36.

Preferably, an annular groove is provided on the outer peripheral surface of the end of the connecting shaft 39, which can be plugged into the limit strip on the inner wall of the guide groove, thereby driving the connecting plate 36 to move in the horizontal direction. After the stainless steel plate 2 clamped by the clamp 2 11 contacts the stainless steel plate 1, the slide 1 2 remains in a moving state, so that the stainless steel plate 2 moves in a direction close to the drive motor 3, and drives the abutment member 31 to move through the connecting plate 36. After the abutment member 31 moves, it contacts the limit plate 26 and causes the slide tube 25 to lose its limit state.

[0042] A bevel gear 1 41 is rotatably arranged on the top surface of the upper chamber 23; the bottom end of the lead screw 2 34 is fixedly connected to the bevel gear 1 41. A support plate 42 is vertically fixedly arranged on the top surface of the upper chamber 23, and a bevel gear 2 43 is rotatably arranged on the support plate 42 in the direction close to the bevel gear 1 41, and the bevel gear 2 43 meshes with the bevel gear 1 41. A rotating rod 44 is axially slidably arranged on the support plate 42 along the bevel gear 2 43; the rotating rod 44 penetrates the bevel gear 2 43 and is coaxially slidably connected with the bevel gear 2 43; a limit strip is arranged on the circumference of the rotating rod 44 to slide with the bevel gear 2 43, so that the bevel gear 2 43 rotates with the rotating rod 44.

[0043] A connecting piece 3 45 is fixedly provided on the side wall of the connecting plate 36 near the abutting piece 1 31, and the connecting piece 3 45 extends into the upper chamber 23. A connecting pipe 46 is fixedly provided on one end of the connecting piece 3 45 away from the connecting plate 36 through a connecting arm; the connecting pipe 46 is sleeved on the peripheral side of the rotating rod 44 and is rotatably connected to the rotating rod 44; preferably, a limiting groove 16 is provided on the peripheral side of the rotating rod 44 to rotatably cooperate with the connecting pipe 46, so that the rotating rod 44 moves along with the connecting pipe 46.

[0044] The inner wall of the slide 2 away from the abutment 31 is provided with a plurality of transmission gears meshing with each other. The plurality of transmission gears are arranged vertically; the lead screw 22 penetrates the transmission gear 47 located at the bottom, and the inner circumference of the gear groove 48 of the axis of the transmission gear 47 is used to accommodate the lead screw 22, and a plurality of connecting strips are fixedly provided; the peripheral side of the lead screw 22 is provided with a connecting groove 4 plugged with the connecting strip along its own axial direction, so that the transmission gear 47 rotates with the lead screw 22 during the sliding cooperation with the lead screw 22. A transmission shaft 49 is coaxially fixedly provided on the transmission gear 29 located at the top of the plurality of transmission gears; after the connecting tube 46 drives the transmission shaft 49 to move, the transmission shaft 49 meshes with the rotating rod 44.

[0045] Specifically, the end of the transmission shaft 49 close to the rotating rod 44 is evenly distributed with a plurality of engaging teeth along its circumference; the end of the rotating rod 44 is evenly distributed with a plurality of engaging grooves that can be plugged with the engaging teeth along its circumference. After the connecting tube 46 drives the rotating rod 44 to move, the rotating rod 44 contacts the transmission shaft 49 and rotates with the transmission shaft 49.

[0046] Specifically, after the slide 1 2 moves to the point where the stainless steel plate 2 contacts the stainless steel plate 1, the stainless steel plate 2 moves under pressure, and the connecting plate 36 drives the abutting member 1 31 to contact the limiting plate 26. The abutting member 1 31 presses the limiting plate 26 to separate the limiting plate 26 from the slide tube 25. The slide tube 25, which loses its limiting function, rotates along with the lead screw 1 22, so that the slide 1 2 stops moving in the horizontal direction. At the same time, since a number of transmission gears rotate along with the lead screw 1 22, the transmission shaft 49 still keeps rotating. After the connecting plate 36 moves toward the direction close to the slide tube 25, the connecting tube 46 synchronously moves toward the direction close to the transmission gear; the transmission shaft 49 moves along with the connecting tube 46 and contacts the rotating rod 44, and the rotating rod 44 drives the transmission shaft 49 to rotate, and synchronously drives the bevel gear 1 41 and the bevel gear 2 43 to rotate.

Preferably, a guide rod is fixedly provided at the top of the second slide 21, and the sliding member 35 on the second slide 21 is slidably matched with the guide rod.

[0047] Specifically, during the rising process of stainless steel plate 2, when the notch on stainless steel plate 2 is plugged into the convex part on stainless steel plate 1, stainless steel plate 2 moves toward stainless steel plate 1, and the reset stroke of stainless steel plate 2 is less than the movement stroke when stainless steel plate 2 and stainless steel plate 1 first contact. At this time, the limit plate 26 is still in contact with the abutment member 1 31, the limit plate 26 is separated from the slide tube 25, and the lead screw 1 22 remains in a stopped state; at the same time, the rotating rod 44 is separated from the transmission shaft 49, and the lead screw 2 34 stops rotating.

[0048] The inner wall of the abutment groove 38 away from the connecting plate 36 is fixed with an electromagnet 2, and the side wall of the abutment member 37 is fixed with a metal sheet that can be magnetically attracted to the electromagnet 2. The top surface of the slide 1 2 is provided with a contact switch 2. When the slide member 35 moves downward and contacts the top surface of the slide 1 2, the contact switch 2 is closed, otherwise the contact switch 2 is opened; the electromagnet 2 is connected to the power supply through the contact switch 2.

[0049] Specifically, after the stainless steel plate 1 and the stainless steel plate 2 are aligned, the clamping jaw 2 11 is separated from the stainless steel plate 2. The driving motor 3 is started and the driving shaft is rotated in the opposite direction, and the electromagnet 2 is started at the same time; the adsorption effect of the electromagnet 2 on the abutment member 2 37 makes the limit plate 26 still keep in contact with the abutment member 1 31, and the limit plate 26 is separated from the slide tube 25; at the same time, the rotating rod 44 contacts the transmission shaft 49, and drives the lead screw 2 34 to rotate in the opposite direction, so that the clamping jaw 2 11 moves downward. After the sliding member 35 moves to the bottom of the lead screw 2 34, it contacts the contact switch 2 on the slide seat 1 2, so that the electromagnet 2 is de-energized; the abutment member 2 37 drives the connecting member to move in the direction away from the slide seat 1 2, and during the movement of the connecting plate 36, the rotating rod 44 is separated from the transmission shaft 49, and the limit plate 26 is plugged into the slide tube 25; the lead screw 2 34 stops rotating, and at the same time, the lead screw 1 22 and the slide tube 25 are threadedly matched, and the slide seat 1 2 moves to the initial position driven by the reverse rotation of the lead screw 1 22.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
