The first mounting member 40a and the second mounting member 40b correspond to each other, and the first mounting member 40a and the second mounting member 40b are respectively used for detachably mounting on the base 101 of the conveyor line 100. When the first mounting member 40a and the second mounting member 40b are respectively mounted on the base 101 of the conveyor line 100, the length direction of the frame 10 is the same as the length direction of the base 101 of the conveyor line 100, and the frame 10 is located above the base 101. In this embodiment, the first mounting member 40a and the second mounting member 40b are respectively three, and the three first mounting members 40a and the three second mounting members 40b are respectively arranged at intervals along the length direction of the frame 10. It can be understood that the number of the first mounting member 40a and the second mounting member 40b can be set according to the actual situation.

[0026] In this embodiment, both the first mounting member 40a and the second mounting member 40b include a fixing plate 41 and a connecting plate 42. The fixing plates 41 of the first mounting member 40a and the second mounting member 40b are respectively arranged on both sides of the bottom end of the frame 10.

The connecting plate 42 is provided with a connecting plate waist-shaped hole 421 (the connecting plate waist-shaped hole 421 is a hole with semicircles at both ends and a rectangle in the middle) extending along the length direction of the frame 10. The connecting plate waist-shaped hole 42 is located below the fixing plate 41. The connecting plate 42 is used for detachably mounting on the base 101 of the conveyor line 100 through the connecting plate waist-shaped hole 421. In actual application, on both sides of the top end of the base 101, there are respectively a first round hole and a second round hole corresponding to the connecting plate waist-shaped hole 421 of the first mounting member 40a and the connecting plate waist-shaped hole 421 of the second mounting member 40b. A first fastener such as a screw is installed in the connecting plate waist-shaped hole 421 of the first mounting member 40a and the corresponding first round hole, and a second fastener such as a screw is installed in the connecting plate waist-shaped hole 421 of the second mounting member 40b and the corresponding second round hole, so as to realize mounting the connecting plates 42 of the first mounting member 40a and the second mounting member 40b on the base 101 of the conveyor line 100 respectively. The number of the connecting plate waist-shaped holes 421 can be set according to the actual situation. By installing the first fastener at different positions in the connecting plate waist-shaped hole 421 of the first mounting member 40a and installing the second fastener at different positions in the connecting plate waist-shaped hole 421 of the second mounting member 40b, the left and right positions of the frame 10 can be adjusted. For example, if in the initial state, the first fastener is installed at the middle position of the connecting plate waist-shaped hole 421 of the first mounting member 40a and the second fastener is installed at the middle position of the connecting plate waist-shaped hole 421 of the second mounting member 40b, when the frame 100 needs to be moved to the left, the first fastener and the second fastener can be disassembled first, then the frame 10, the first mounting member 40a and the second mounting member 40b are moved to the left, and then the first fastener is installed in the connecting plate waist-shaped hole 421 of the first mounting member 40a and the corresponding first round hole, and the second fastener is installed in the connecting plate waist-shaped hole 421 of the second mounting member 40b and the corresponding second round hole. When the frame 10 needs to be moved to the right, the first fastener and the second fastener can be disassembled first, then the frame 10, the first mounting member 40a and the second mounting member 40b are moved to the right, and then the first fastener is installed in the connecting plate waist-shaped hole 421 of the first mounting member 40a and the corresponding first round hole, and the second fastener is installed in the connecting plate waist-shaped hole 421 of the second mounting member 40b.

The fixed plate waist-shaped hole 411 corresponds to the round hole 422, and fasteners such as screws are installed in the fixed plate waist-shaped hole 411 and the corresponding round hole 422. The number of the fixed plate waist-shaped holes 411 and the round holes 422 can be set according to the actual situation. By installing the fasteners at different positions in the fixed plate waist-shaped hole 411, the height position of the frame 10 can be adjusted to adapt to trays 200 of different heights. For example, in the initial state, if the fasteners are installed at the middle position of the fixed plate waist-shaped hole 411, when the height of the frame 10 needs to be lowered, the fasteners can be removed first, then the frame 10, the fixed plate 41 of the first mounting member 40a, and the fixed plate 41 of the second mounting member 40b can be moved downward, and then the fasteners can be installed in the fixed plate waist-shaped hole 411 and the corresponding round hole 422. When the height of the frame 10 needs to be raised, the fasteners can be removed first, then the frame 10, the fixed plate 411 of the first mounting member 40a, and the fixed plate 411 of the second mounting member 40b can be moved upward, and then the fasteners can be installed in the fixed plate waist-shaped hole 411 and the corresponding round hole 422.

[0029] The opening and closing door panel 20 is provided with a window penetrating through its top end and bottom end, and a transparent plate 50 corresponding to the window is arranged at the top end of the opening and closing door panel 20. In actual application, when the opening and closing door panel 20 is located above the tray 200, the transparent plate 50 and the window are provided to facilitate observing the situation inside the tray 200.

[0030] The driving member 30 is arranged on the inner wall of one side of the frame 10. In this embodiment, the driving member 30 is arranged on the inner wall of one side of the frame 10 through the cylinder plate 31. Preferably, there are two cylinder plates 31, and the two cylinder plates 31 are arranged at intervals along the length direction of the frame 10. It can be understood that the number of the cylinder plates 31 can be set according to the actual situation. The output end of the driving member 30 is connected to the bottom end of the opening and closing door panel 20, and the driving member 30 is used to drive the opening and closing door panel 20 to make a reciprocating linear movement along the length direction of the frame 10, that is, move left and right along the length direction of the frame 10. The transparent plate 50 can move synchronously with the opening and closing door panel 20.

[0031] A connecting block is arranged at the bottom end of the opening and closing door panel 20, and the output end of the driving member 30 is connected to the connecting block.

[0032] Combined Figure 2 and Figure 3 As shown, first brackets 12 and second brackets 13 are respectively arranged at both ends of the slide rail 11. The first brackets 12 and the second brackets 13 are respectively fixed at the top end of the frame 10, and the opening and closing door panel 20 is located between the first brackets 12 and the second brackets 13. A first buffer pad 121 is arranged on the side of the first bracket 12 close to the opening and closing door panel 20. The first buffer pad 121 is located above the slide rail 11 and corresponds to the opening and closing door panel 20. A second buffer pad 131 is arranged on the side of the second bracket 13 close to the opening and closing door panel 20. The second buffer pad 131 is located above the slide rail 11 and corresponds to the opening and closing door panel 20.

[0033] A first induction switch 14 and a second induction switch 15 are arranged in the frame 10. The first induction switch 14 and the second induction switch 15 are arranged at intervals along the length direction of the frame 10 and are both close to the inner wall of the other side of the frame 10. One end of the opening and closing door panel 20 is provided with an L-shaped induction piece 18. The induction piece 18 can move synchronously with the opening and closing door panel 20, and the induction piece 18 is located above the first induction switch 14 and the second induction switch 15. The first induction switch 14 corresponds to the first buffer pad 121, and the second induction switch 15 is located between the first buffer pad 121 and the second buffer pad 131. The first induction switch 14 and the second induction switch 15 are respectively used to sense the induction piece 18 and send out induction signals.

[0034] In actual application, during the process of driving the opening and closing door panel 20 to move along the length direction of the frame 10 by the driving member 30, when one end of the opening and closing door panel 20 abuts against the first buffer pad 121, at this time, the first induction switch 14 can sense the induction sheet 18 and send out an induction signal, and the driving member 30 stops driving the opening and closing door panel 20 to move according to the induction signal sent out by the first induction switch 14. When the other end of the opening and closing door panel 20 abuts against the second buffer pad 131, at this time, the second induction switch 14 can sense the induction sheet 18 and send out an induction signal, and the driving member 30 stops driving the opening and closing door panel 20 to move according to the induction signal sent out by the second induction switch 15. The first induction switch 14, the second induction switch 15 and the induction sheet 18 provided can accurately limit the moving range of the opening and closing door panel 20. The first buffer pad 121 and the second buffer pad 131 provided play a buffering role and can avoid damaging the opening and closing door panel 20.

[0035] Both the first buffer pad 121 and the second buffer pad 131 are polyurethane pads and have characteristics such as good wear resistance and good elasticity. Both the first induction switch 14 and the second induction switch 15 are, for example, photoelectric switches, etc. It can be understood that the first induction switch 14 and the second induction switch 15 can also be of other types.

[0036] In this embodiment, the first induction switch 14 is arranged on one side of the first switch bracket 141. The bottom end of the first switch bracket 141 is provided with a first mounting plate 142. The first switch bracket 141 and the first mounting plate 142 form an L-shaped structure, and the first mounting plate 142 is arranged at the bottom end of the frame 10. The second induction switch 15 is arranged on one side of the second switch bracket 151. The bottom end of the second switch bracket 151 is provided with a second mounting plate 152. The second switch bracket 151 and the second mounting plate 152 form an L-shaped structure, and the second mounting plate 152 is arranged at the bottom end of the frame 10. The first switch bracket 141 and the first mounting plate 142 provided play a role in installing and supporting the first induction switch 14, and the second switch bracket 151 and the second mounting plate 152 provided play a role in installing and supporting the second induction switch 15.

[0037] With the above structure, in actual application, the automatic telescopic protective cover mechanism is installed on the base 101 of the conveyor line 100, and the robotic arm 300 is arranged on the right side of the conveyor line 100. In the initial state, one end of the opening and closing door panel 20 abuts against the first buffer pad 121. When the pallet 200 loaded with batteries is conveyed to the robotic arm 300 on the right by a plurality of conveyor rollers 102 arranged on the base 101 of the conveyor line 101, at this time, the opening and closing door panel 20 is located on the left side of the pallet 200. After the robotic arm 300 grabs a single battery in the pallet 200, the driving member 30 drives the opening and closing door panel 20 to move along the length direction of the frame 10 towards the direction close to the robotic arm 300. When the other end of the opening and closing door panel 20 abuts against the second buffer pad 131, at this time, the second inductive switch 15 can sense the inductive sheet 18 and send out an inductive signal, and the driving member stops driving the opening and closing door panel 20 to move according to the inductive signal sent out by the second inductive switch 15. At this time, the opening and closing door panel 20 is located above the pallet 200. In this way, the opening and closing door panel 20 can block the pallet 200, so as to protect the batteries in the pallet 200. When the battery grabbed by the robotic arm 300 drops, the battery will not drop into the pallet 200, so the batteries in the pallet 200 will not be damaged. After the robotic arm 300 classifies the grabbed batteries, the driving member 30 drives the opening and closing door panel 20 to move along the length direction of the frame 10 towards the direction away from the robotic arm 300. When one end of the opening and closing door panel 20 abuts against the first buffer pad 121, at this time, the first inductive switch 14 can sense the inductive sheet 18 and send out an inductive signal, and the driving member 30 stops driving the opening and closing door panel 20 to move according to the inductive signal sent out by the first inductive switch 14. At this time, the opening and closing door panel 20 is located on the left side of the pallet 200. In this way, the opening and closing door panel 20 will not block the pallet 200, so that the robotic arm 300 can continue to grab the next battery in the pallet 200, take out the next battery from the pallet 200 and classify and place it. Just do it like this.

[0038] In this embodiment, the opening and closing door panel 20 is a carbon steel plate. The carbon steel plate has the characteristics of high wear resistance, etc., can resist more collisions and frictions, is not easily damaged, and the surface of the carbon steel plate is treated with powder spraying, such as spraying metal powder or ceramic powder, so as to effectively block the corrosion of the outside air, moisture, etc. to the carbon steel plate and extend the service life of the carbon steel plate. The transparent plate 50 is a transparent PC (polycarbonate) plate, which has the characteristics of high strength, corrosion resistance, etc. and is not easily damaged.

[0039] The automatic telescopic protective cover mechanism of the present utility model, through the provided frame 10, opening and closing door panel 20 and driving member 30, in actual application, after a single battery in the tray 200 is grasped by the robotic arm 300, the driving member 30 drives the opening and closing door panel 20 to move along the length direction of the frame 10 towards the direction close to the robotic arm 300, so that the tray 200 can be blocked by the opening and closing door panel 20, thereby protecting the battery in the tray 200. When the battery grasped by the robotic arm 300 drops, the battery will not fall into the tray 200, so the battery in the tray 200 will not be damaged. After the battery grasped by the robotic arm 300 is sorted and placed, the driving member 30 drives the opening and closing door panel 20 to move along the length direction of the frame 10 towards the direction away from the robotic arm 300, so that the tray 200 will not be blocked by the opening and closing door panel 20. In this way, the robotic arm 300 can continue to grasp the next battery in the tray 200 to take out the next battery from the tray 200 and sort and place it. The structure of the present utility model is simple and easy to assemble.
