Description

Technical Field

[0001] The utility model belongs to the technical field of battery core production equipment, and particularly relates to a pole piece suction plate mechanism. Background Art

[0002] The electrode sheets of the battery cell are in the form of smooth thin sheets. In the battery manufacturing process, a robot is usually used to operate a electrode sheet suction plate mechanism to transport the electrode sheets from one place to another and stack them alternately. The electrode sheet suction plate mechanism includes a suction plate, on which a plurality of vacuum suction cups are arranged. The electrode sheets are adsorbed by the adsorption effect of the vacuum suction cups, thereby realizing the transportation of the electrode sheets. However, since the electrode sheets are very thin, adhesion is easily generated between the upper and lower electrode sheets. When the existing electrode sheet suction plate mechanism is used to transport the electrode sheets, it is easy to suck two or even more electrode sheets at the same time, thereby causing the problem of electrode sheet sticking. In addition, when the robot operates the electrode sheet suction plate mechanism to suck the electrode sheet, it is easy to press down too much and cause damage to the electrode sheet. At the same time, since the distance between the vacuum suction cup and the suction plate cannot be adjusted, the problem of uneven electrode sheet absorption is easy to occur when sucking the electrode sheet. Utility Model Content

[0003] In response to the current technical problems, the present invention aims to provide a pole piece suction plate mechanism, which can solve the technical problem of pole piece adhesion in the prior art.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A pole piece suction plate mechanism includes a first suction plate, and its structural features include: a second suction plate, a driving mechanism, a cam follower, a cam groove and at least two vacuum suction cups, the cam on the cam follower cooperates with the cam groove; the second suction plate is arranged at one end of the first suction plate and is rotatably connected to the first suction plate; at least one vacuum suction cup is provided on the same side of the first suction plate and the second suction plate, and the outer end of the vacuum suction cup passes through the first suction plate or the second suction plate; the driving mechanism is arranged on the first suction plate, the output end of the driving mechanism is connected to the cam follower, the cam on the cam follower is arranged in the cam groove, and the cam groove is arranged on the second suction plate.

[0006] When the electrode plate suction mechanism is in use, the drive mechanism drives the cam follower to move and rotate the second suction plate until it is parallel to the first suction plate. The vacuum cups on the first and second suction plates are then evacuated, causing the electrode to adhere to the bottoms of the first and second suction plates. The manipulator is then operated to raise the electrode plate suction mechanism. The drive mechanism is operated to extend and retract at a constant frequency. The cam follower's cam moves up and down in the cam slot, causing the second suction plate to vibrate up and down. The second suction plate then drives the top electrode plate up and down, creating a gap between the top and bottom electrodes, eliminating adhesion and effectively resolving the prior art problem of electrode material sticking.

[0007] Preferably, a first mounting plate is provided above the first suction plate, connected to the first suction plate via a support plate. A first elastic element is installed between the first mounting plate and the second suction plate, with the first elastic element and the drive mechanism located on the same side of the first suction plate. The first elastic element can provide a buffer against the up and down vibration of the second suction plate.

[0008] Preferably, a second mounting plate is provided above the first mounting plate, and a second elastic element is installed between the first and second mounting plates, with a ball bushing disposed therein. When the second mounting plate is subjected to an external force, the second mounting plate can move downward relative to the first mounting plate. The second elastic element is provided to cushion the downward movement of the electrode plate suction mechanism and to allow a certain amount of overpressure when pressing down to suction the electrode plate.

[0009] Preferably, a slot-shaped photoelectric switch is provided on the side wall of the second mounting plate, and a slot-shaped photoelectric sensing sheet is provided on the first mounting plate, the slot-shaped photoelectric sensing sheet cooperating with the slot-shaped photoelectric switch. When the slot-shaped photoelectric sensing sheet triggers a signal from the slot-shaped photoelectric switch, the slot-shaped photoelectric switch outputs an in-position signal, causing the electrode plate suction mechanism to stop pressing downward, thereby preventing the electrode plate from being damaged due to excessive downward pressure from the electrode plate suction mechanism.

[0010] Preferably, there are two slot-shaped photoelectric switches, which are arranged along the height direction of the second mounting plate. The slot-shaped photoelectric switch located above is mainly used as a backup. When the slot-shaped photoelectric switch located above is triggered, the electrode plate suction mechanism is locked, causing the electrode plate suction mechanism to stop pressing down.

[0011] Preferably, when the driving mechanism drives the second suction plate to rotate side by side with the first suction plate, the bottoms of the first suction plate and the second suction plate are located on the same plane.

[0012] Preferably, the tops of the first and second suction plates are each provided with an inverted U-shaped mounting groove, through which the vacuum suction cup extends and is adjustably fixedly connected; the first and second suction plates are each provided with a plurality of through holes along their thickness, the through holes being located below the mounting groove, with the outer ends of the vacuum suction cup located within the through holes. By adjusting the position of the vacuum suction cup, when the vacuum suction cup first contacts and holds the electrode, the electrode suction plate mechanism continues to press down until the electrode is in close contact with the lower surfaces of the first and second suction plates, thereby ensuring the smoothness of the electrode during suction.

[0013] Preferably, the vacuum suction cup is provided with a threaded section where it passes through the mounting groove, and the vacuum suction cup and the mounting groove are fastened by a nut fastener. The provision of the threaded section facilitates adjustment of the mounting position of the vacuum suction cup and the mounting groove, thereby facilitating adjustment of the relative positions of the vacuum suction cup and the first and second suction plates.

[0014] Preferably, the driving mechanism is a slide cylinder.

[0015] Preferably, the vacuum suction cup is an accordion-type suction cup. The outer end of the accordion-type suction cup is made of rubber material, which can provide a slight buffer, thereby reducing the marks left on the pole piece when the pole piece suction plate mechanism presses down to suck the pole piece.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The electrode plate suction mechanism of the present invention is provided with a second suction plate, which is rotatably connected to the first suction plate. When sucking the electrode, the second suction plate is shaken up and down, thereby effectively solving the technical problem of electrode sticking in the prior art;

[0018] (2) The electrode plate suction mechanism of the present invention is provided with a slot-shaped photoelectric switch, thereby preventing the electrode plate from being damaged due to excessive downward pressure when the electrode plate suction mechanism is pressed down;

[0019] (3) The electrode plate suction mechanism of the present invention ensures the flatness of the electrode plate when sucking the electrode plate by setting the connection method between the vacuum suction cup and the first suction plate and the second suction plate.

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0025] like Figure 1As shown, the electrode plate suction mechanism disclosed in this embodiment includes a first suction plate 4, a second suction plate 5, a driving mechanism 10, a cam follower 6, a cam groove 7, and eight vacuum suction cups 1. The model of the cam follower 6 is BPB11-d4, and the cam on the cam follower 6 cooperates with the cam groove 7. The second suction plate 5 is arranged on one side of the first suction plate 4 and is rotatably connected to the first suction plate 4 via a rotating shaft. When the second suction plate 5 rotates to be side by side with the first suction plate 4, the bottoms of the first suction plate 4 and the second suction plate 5 are located on the same plane. Figure 2 As shown, the drive mechanism 10 utilizes a slide cylinder, which is mounted atop the first suction plate 4. The output end of the slide cylinder is connected to a cam follower 6, whose cam is positioned within a cam slot 7, which is positioned atop the second suction plate 5. When the slide cylinder extends or retracts, the cam on the cam follower 6 rolls within the cam slot 7, thereby controlling the up and down reciprocating movement of the second suction plate 5. A first mounting plate 14 is positioned above the first suction plate 4. This first mounting plate 14 is connected to the first suction plate 4 via two support plates 16. A first elastic element 9 is mounted between the first mounting plate 14 and the second suction plate 5. This first elastic element 9 and the drive mechanism 10 are located on the same side of the first suction plate 4. The first elastic element 9 utilizes a suspension spring, with suspension rings 2 positioned between each end of the suspension spring and the first mounting plate 14 and the second suction plate 5. A second mounting plate 15 is located above the first mounting plate 14. A second elastic element 12 is installed between the first and second mounting plates 14, 15. This second elastic element 12 houses a ball bearing bushing 13 and utilizes a buffer spring. Under external force, the second mounting plate 15 can move downward relative to the first mounting plate 14, with the second elastic element 12 providing a buffer. Two slot-shaped photoelectric switches 11 are positioned along the sidewalls of the second mounting plate 15, along their height. A slot-shaped photoelectric sensor sheet 3 is located on the first mounting plate 14, which cooperates with the slot-shaped photoelectric switches 11. The vacuum suction cup 1 utilizes an accordion-type suction cup, with six accordion-shaped suction cups on the first suction plate 4 and two on the second suction plate 5. When the second suction plate 5 rotates to align with the first suction plate 4, the accordion-shaped suction cups on the first and second suction plates 4, 5, are arranged side by side in two rows with intervals. The first and second suction plates 4 and 5 each have through-holes where the accordion-shaped suction cups are located. The tops of these through-holes are each provided with inverted U-shaped mounting slots 8. The accordion-shaped suction cups extend through these mounting slots 8 and are adjustably and securely connected thereto. The outer ends of the accordion-shaped suction cups are positioned within the through-holes. A threaded section is provided where the accordion-shaped suction cups extend through the mounting slots 8. The accordion-shaped suction cups are secured to the mounting slots 8 using nut fasteners.

[0026] The first suction plate 4 and the second suction plate 5 are arranged side by side, and the bottoms of the first suction plate 4 and the second suction plate 5 are located on the same plane. When the manipulator operates the entire electrode suction mechanism to press down, the accordion-shaped suction cup first contacts the electrode and sucks the electrode, and continues to press down until the electrode is close to the first suction plate 4 and the second suction plate 5. Since the first suction plate 4 and the second suction plate 5 are located on the same plane, the flatness of the electrode can be guaranteed when the electrode is sucked. Then the buffer spring starts to buffer, the slot-shaped photoelectric sensor sheet 3 triggers the slot-shaped photoelectric switch 11 signal, and the electrode suction mechanism stops pressing down, thereby preventing the electrode from being damaged when the electrode suction mechanism is pressed down to suck. Then the manipulator operates the entire electrode suction mechanism to rise, rise to a certain height, control the slide cylinder to extend and retract at a certain frequency, and the cam on the cam follower 6 moves up and down in the cam groove 7, thereby linking the second suction plate 5 to shake up and down, preventing the electrode from sticking together.

[0027] The contents described in the above embodiments should be understood as these embodiments are only used to more clearly illustrate the present invention, and are not used to limit the scope of the present invention. After reading the present invention, various equivalent modifications to the embodiments made by those skilled in the art fall within the scope defined by the claims attached to the present invention.
