Description

Technical Field

[0001] This utility model relates to the field of tablet pressing equipment technology, and in particular to a tablet pressing device for lithium battery manufacturing. Background Technology

[0002] In the production process of lithium batteries, pressing equipment is often used to press the stacked electrode sheets together, thereby preventing the lithium battery from bulging due to air entering the interior.

[0003] Existing lithium battery manufacturing pressing equipment typically involves stacking multiple electrode sheets in a groove on a placement table, then using a hydraulic rod to move a pressure plate up and down, squeezing the multiple electrode sheets inside the groove to form a tightly bonded sheet, thus completing the pressing and forming of the lithium battery electrode sheet. However, because the multiple electrode sheets are tightly bonded to the inner wall of the groove on the placement table after pressing, it may be time-consuming and laborious for personnel to handle the material, affecting processing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pressing device for lithium battery manufacturing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressing device for lithium battery manufacturing, comprising a body, a hydraulic rod on one side of the body, a pressure plate at one end of the hydraulic rod, a placement platform on one side of the body, a control button on one side of the body, an ejection device inside the placement platform, and an anti-accidental contact device on the side of the body near the control button. The ejection device includes a rectangular groove on one side of the placement platform, an electric telescopic rod fixedly connected to the inner wall of the rectangular groove, a top plate fixedly connected to the moving end of the electric telescopic rod, the surface of the top plate being slidably connected to the inner wall of the rectangular groove, a cylinder fixedly connected to one side of the top plate, a round rod fixedly connected to the inner wall of the rectangular groove, the surface of the round rod being slidably connected to the inner wall of the cylinder, a piston plate fixedly connected to one end of the round rod, and the surface of the piston plate being slidably connected to the inner wall of the cylinder.

[0006] The effect achieved by the above-mentioned components is as follows: By setting up the ejection device, the electric telescopic rod is first activated, causing the electric telescopic rod to move the top plate away from the interior of the rectangular groove. This causes the top plate to move the electrode sheet inside the placement table away from the placement table, allowing the electrode sheet to be quickly moved out of the placement table. At the same time, the top plate moves the cylinder away from the interior of the rectangular groove. Under the limiting action of the cylinder rod on the piston plate, the piston plate slides along the inside of the cylinder and draws out the air inside the cylinder, generating suction inside the cylinder. This causes the cylinder to pick up the electrode sheet placed on the top plate, making the electrode sheet tightly adhered to the surface of the top plate. This achieves fast and stable electrode sheet picking, reducing the situation where multiple electrode sheets are placed in the placement table for pressing and forming, and adhere tightly to the inner wall of the groove of the placement table, which makes it time-consuming and laborious for personnel to pick up the material. This improves the efficiency of electrode sheet picking and processing.

[0007] Preferably, a reinforcing block is fixedly connected to one side of the round rod, and the reinforcing block is fixedly connected to the inner wall of the rectangular groove.

[0008] The effect achieved by the above-mentioned components is that by setting up reinforcing blocks, the connection between the round rod and the inner wall of the rectangular groove can be strengthened, reducing the possibility of the round rod separating from the inner wall of the rectangular groove during use.

[0009] Preferably, a limiting ring is fixedly connected to the inner wall of the rectangular groove, and the limiting ring is sleeved on the surface of the cylinder.

[0010] The effect achieved by the above components is as follows: by setting the limiting ring, the limiting ring can assist in limiting the cylinder, reducing the shaking of the cylinder during use. At the same time, the limiting of the cylinder can also assist in limiting the top plate.

[0011] Preferably, a support block is fixedly connected to one end of the electric telescopic rod near the top plate, and the support block is fixedly connected to the top plate.

[0012] The effect achieved by the above components is that by setting up support blocks, the range of the electric telescopic rod's pushing action on the top plate can be increased, and the occurrence of a central bulge when the electric telescopic rod pushes the top plate to move can be reduced.

[0013] Preferably, the top plate has multiple auxiliary grooves on one side, and the multiple auxiliary grooves are arranged at equal intervals.

[0014] The effect achieved by the above components is that by setting the auxiliary groove, the contact area between the top plate and the electrode surface can be reduced, thus reducing the tight adhesion between the top plate and the electrode surface.

[0015] Preferably, the anti-accidental touch device includes a rectangular frame, which is fixedly connected to the side of the machine body near the control button. The rectangular frame is fitted onto the surface of the control button, and a baffle is slidably connected to the inner wall of the rectangular frame. A push plate is fixedly connected to one side of the baffle.

[0016] The effect achieved by the above components is as follows: by setting up an anti-accidental touch device, the push plate is first manually moved, so that the push plate drives the baffle to move left and right along the inside of the rectangular frame. When the baffle moves to the position where it is completely inside the rectangular frame, the baffle works with the rectangular frame to completely cover the control buttons inside and intercept external objects, reducing the situation where personnel accidentally touch the control buttons when loading and unloading materials, causing changes in the machine's operating program and affecting processing.

[0017] Preferably, a plurality of rubber strips are fixedly connected to one side of the push plate, and the plurality of rubber strips are arranged at equal intervals.

[0018] The effect achieved by the above components is that by setting the rubber strip, the friction between the push plate and the hand can be increased, reducing the chance of the hand slipping when manually moving the push plate.

[0019] Preferably, a cylindrical block is fixedly connected to the side of the baffle away from the push plate, and the surface of the cylindrical block is higher than the surface of the baffle.

[0020] The effect achieved by the above components is that by setting up cylindrical blocks, the cylindrical blocks can assist in intercepting the baffles during the movement process, reducing the possibility of the baffles accidentally leaving the rectangular frame during the movement.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting an ejector device, the electrode sheets inside the placement table can be quickly and stably retrieved. This reduces the situation where multiple electrode sheets are placed in the placement table for pressing and forming, and adhere tightly to the inner wall of the groove of the placement table, which makes it time-consuming and laborious for personnel to retrieve the materials. This improves the efficiency of electrode sheet retrieval and processing. Attached Figure Description

By setting the ejection device 6, the electric telescopic rod 61 is first activated, causing the electric telescopic rod 61 to move the top plate 62 away from the inside of the rectangular groove 610. This causes the top plate 62 to move the electrode sheet inside the placement table 4 away from the placement table 4, allowing the electrode sheet to be quickly moved out of the placement table 4. At the same time, the top plate 62 moves the cylinder 63 away from the inside of the rectangular groove 610. Under the limiting action of the cylinder rod 64 on the piston plate 65, the piston plate 65 slides along the inside of the cylinder 63 and draws out the air inside the cylinder 63, generating suction inside the cylinder 63. This causes the cylinder 63 to pick up the electrode sheet placed on the top plate 62, making the electrode sheet tightly adhered to the surface of the top plate 62. This achieves fast and stable electrode sheet picking, reducing the time-consuming and laborious process of picking up the electrode sheet when multiple electrode sheets are placed in the placement table 4 and pressed into sheets, which are more tightly adhered to the inner wall of the groove of the placement table 4. This improves the efficiency of electrode sheet picking and processing.

The reinforcing block 67 is fixedly connected to the inner wall of the rectangular groove 610. By setting the reinforcing block 67, the connection between the round rod 64 and the inner wall of the rectangular groove 610 can be strengthened, reducing the possibility of the round rod 64 separating from the inner wall of the rectangular groove 610 during use. A limiting ring 68 is fixedly connected to the inner wall of the rectangular groove 610. The limiting ring 68 is sleeved on the surface of the cylinder 63. By setting the limiting ring 68, the limiting ring 68 can provide auxiliary limiting for the cylinder 63, reducing the possibility of the cylinder 63 shaking during use. At the same time, the limiting of the cylinder 63 can also provide auxiliary limiting for the top plate 62.

The support block 69 is fixedly connected to the top plate 62. By setting the support block 69, the support block 69 can increase the pushing range of the electric telescopic rod 61 on the top plate 62 and reduce the situation where the electric telescopic rod 61 bulges in the middle when pushing the top plate 62 to move. A plurality of auxiliary grooves 66 are opened on one side of the top plate 62. The plurality of auxiliary grooves 66 are arranged at equal intervals. By setting the auxiliary grooves 66, the auxiliary grooves 66 can reduce the contact area between the top plate 62 and the electrode surface and reduce the situation where the top plate 62 is tightly adhered to the electrode surface.

The rectangular frame 71 is fixedly connected to the side of the machine body 1 near the control button 5. The rectangular frame 71 is fitted onto the surface of the control button 5. A baffle 72 is slidably connected to the inner wall of the rectangular frame 71. A push plate 73 is fixedly connected to one side of the baffle 72. By setting the anti-accidental touch device 7, the push plate 73 is first manually moved, causing the push plate 73 to drive the baffle 72 to move left and right along the inside of the rectangular frame 71. When the baffle 72 moves to the position where it is completely inside the rectangular frame 71, the baffle 72 cooperates with the rectangular frame 71 to completely cover the control button 5 inside and intercept external objects, reducing the situation where personnel accidentally touch the control button 5 when loading and unloading materials, causing changes in the operating program of the machine body 1 and affecting processing.

[0032] Reference Figure 4As shown in the figure, this embodiment discloses that a plurality of rubber strips 74 are fixedly connected to one side of the push plate 73. The plurality of rubber strips 74 are arranged at equal intervals. By setting the rubber strips 74, the rubber strips 74 can increase the friction between the push plate 73 and the hand, reducing the possibility of hand slippage when manually moving the push plate 73. A cylindrical block 75 is fixedly connected to the side of the baffle 72 away from the push plate 73. The surface of the cylindrical block 75 is higher than the surface of the baffle 72. By setting the cylindrical block 75, the cylindrical block 75 can assist in intercepting the baffle 72 during the movement, reducing the possibility of the baffle 72 accidentally leaving the rectangular frame 71 during the movement.

[0033] Working principle: First, multiple electrode sheets are stacked in the groove of the placement platform 4. Then, the hydraulic rod 2 is activated to drive the pressure plate 3 to move up and down and squeeze the multiple electrode sheets inside the groove, so that the multiple electrode sheets are tightly attached in sheet shape, completing the pressing and forming of the lithium battery electrode sheet. At this time, the electric telescopic rod 61 is activated, so that the electric telescopic rod 61 drives the top plate 62 to move away from the inside of the rectangular groove 610. The top plate 62 drives the electrode sheets inside the placement platform 4 to move away from the placement platform 4, so that the electrode sheets are quickly moved out of the inside of the placement platform 4. At the same time, the top plate 62 drives the cylinder 63 to move away from the inside of the rectangular groove 610. Under the limiting action of the cylinder rod 64 on the piston plate 65, the piston plate 65 slides along the inside of the cylinder 63 and draws out the air inside the cylinder 63, so that the cylinder 63 generates suction force, so that the cylinder 63 picks up the electrode sheet placed on the top plate 62, so that the electrode sheet is tightly adsorbed on the surface of the top plate 62, thereby achieving fast and stable material picking of the electrode sheet.

[0034] First, manually move the push plate 73 so that the push plate 73 drives the baffle 72 to move left and right along the inside of the rectangular frame 71. When the baffle 72 moves to the position where it is completely inside the rectangular frame 71, the baffle 72 cooperates with the rectangular frame 71 to completely cover the control button 5 inside and block external objects, thus completing the anti-accidental touch processing of the control button 5.
