Description

Technical Field

[0001] The invention belongs to the technical field of battery production, and in particular relates to a device for producing sealed shock-resistant storage batteries. Background Art

[0002] In the battery production process, there is a process of assembling the positive electrode plate and the negative electrode plate. During the assembly, the negative electrode plate and the positive electrode plate need to be separated by insulating paper. Existing battery factories generally use manual methods to perform this process, but both the positive and negative electrode plates contain lead powder, and manual operation will cause harm to the health of workers. Summary of the invention

[0003] The object of the present invention is to provide a device for producing sealed earthquake-resistant storage batteries, so as to solve the problem of potential safety hazards caused by manual assembly of positive and negative plates in the prior art.

[0004] In order to achieve the above-mentioned purpose, the basic scheme of the present invention is: equipment for producing sealed earthquake-resistant batteries, including a frame and a motor, the motor is fixed on the frame, and also includes a driving part and two groups of plate wrapping units, each group of plate wrapping units includes a cutting knife, a paper feeding part, a plate feeding part and a pushing part, the paper feeding part includes a rotating shaft and insulating paper wound on the rotating shaft, the end of the insulating paper hangs down, and the rotating shaft is driven by the motor; the plate feeding part includes a feeding box and a first baffle arranged horizontally below the feeding box, a plurality of vertical plates are installed in the feeding box, the first baffle and the feeding box are fixed on the frame, the bottom surface of the feeding box is inclined and the lowest point of the bottom surface is close to the hanging insulating paper, the lowest point of the bottom surface of the feeding box is provided with a first opening that can just pass a plate, the first baffle is directly opposite to the first opening and the distance between the first baffle and the first opening is just the height of a plate; the pushing part includes A horizontal first crossbar, a vertically arranged second baffle and a first vertical bar, the second baffle is fixed on the frame, the cutting knife is arranged horizontally, the upper surface of the second baffle can contact the bottom surface of the cutting knife, the cutting knife and the first crossbar are connected to the first vertical bar and are both located below the feed box, the cutting knife and the first crossbar are located on the same side of the first vertical bar and face the second baffle, the second baffle and the feed box are located on both sides of the hanging insulating paper, the second baffle contacts the hanging insulating paper, and a channel that can just pass a plate is formed between the hanging insulating paper and the first baffle; the upper surface of the cutting knife can contact the first opening, and the blade end of the cutting knife is set as an inclined surface, and the inclined surface faces the feed box; the distance difference between the cutting knife and the first crossbar and the second block is the total thickness of a plate and the insulating paper, and the distance between the cutting knife and the second baffle is relatively close; the first vertical bar is horizontally slidably connected to the frame, and the first vertical bar is driven by a driving member.

[0005] The working principle of this basic scheme is: rotate the motor to drive the rotating shaft to rotate, and the rotating shaft drives the insulating paper to rotate until the free end of the insulating paper falls to the same level as the upper surface of the first baffle, and then stop rotating the motor. The positive plate and the negative plate are respectively loaded into the two feed boxes, and a plate located at the first opening will fall from the first opening to the first baffle. Since the bottom surface of the feed box is inclined, the next plate will be filled and moved to the first opening. Since the distance between the first baffle and the first opening is just the height of a plate, the plate located on the first baffle will prevent the next plate from continuing to fall, and the two plates will overlap. Open the drive member, and the drive member drives the first vertical rod, the cutting knife and the first cross bar to move toward the second baffle. When the cutting knife contacts the overlapping part of the two plates, since the blade end of the cutting knife is set as an inclined surface, the inclined surface will push the plate at the first opening upward, so that the cutting knife can pass smoothly. When the first cross bar contacts the plate, it will push the plate to move toward the second baffle. Since the difference in distance between the cutting blade and the first crossbar and the second stopper is the total thickness of a plate and the insulating paper, when the cutting blade cuts the insulating paper, the plate just touches the insulating paper. The driving member is driven in the reverse direction to move the cutting blade and the first crossbar away from the second stopper, and the plate and the cut insulating paper fall downward under the action of gravity, so that they can be collected. Each plate corresponds to a piece of insulating paper, which can be assembled.

[0006] The beneficial effects of this basic solution are: ① This device realizes automatic feeding of the electrode plates by setting the bottom surface of the feed box to be inclined. No additional drive device is required, which saves costs. ② The first cross bar and the cutting knife move synchronously to achieve the simultaneity of pushing the electrode plates and cutting the insulating paper. ③ The blade end of the cutting knife is set as an inclined surface, which can separate the overlapping electrode plates. At the same time, the cutting knife can block the electrode plates in the feed box. When the cutting knife does not contact the first opening, the electrode plates at the first opening will fall down, and will not interfere with the movement of the cutting knife and the first cross bar.

[0007] Furthermore, it also includes a stacking unit, which includes a horizontally arranged third baffle and a loading box and a pushing part located on both sides of the third baffle. The third baffle is located below the two groups of plate packaging units. A second opening is opened on the side of the loading box opposite to the pushing part. A vertical fourth baffle is hinged on the bottom surface of the second baffle. The distance between the fourth baffle and the third baffle is less than the height of a plate, and the distance between the second baffle and the third baffle is greater than the height of a plate. The fourth baffle can only swing toward the loading box, and the pushing part is used to push the insulating paper and plates that fall from the channel into the loading box.

[0008] The insulating paper and plates that fall from the channel will fall onto the third baffle, and the fourth baffle can effectively prevent the fallen plates and insulating paper from tilting toward the board box. At the same time, the push part is started, and the push part will move toward the board box. During the movement, the two sets of insulating paper and plates will be pushed into the board box, so that the plates can be stacked and assembled. During the movement, the insulating paper and plates will push the fourth baffle to swing toward the board box, so that the insulating paper and plates can pass smoothly. Then drive the push part in the reverse direction to restore it to its original position.

[0009] Furthermore, the push part includes a first spring, a second crossbar and a first cylinder arranged horizontally, the two ends of the second crossbar are respectively connected to the first spring and the piston rod of the first cylinder, and the first spring is directly opposite to the board loading box. The first cylinder pushes the first spring and the second crossbar to move the same distance each time, and because the first spring can be extended and retracted, the push part can adapt to the number of stacked plates in the board loading box.

[0010] Furthermore, a horizontal fifth baffle is provided between the two fourth baffles, the fifth baffle is fixed on the frame, the fifth baffle is located below the first baffle and does not interfere with the fourth baffle; a horizontal slide is provided on the bottom surface of the fifth baffle, the distance between the slide and the third baffle is the height of one electrode plate, and the electrode plate can be slidably connected in the slide. When the pushing part pushes the electrode plate to move toward the board box, the electrode plate will be between the third block and the slide, effectively limiting the movement direction of the electrode plate so that it will not deviate and can smoothly enter the board box.

[0011] Furthermore, a plurality of through holes are formed on the upper surface of the loading box, and a wedge block is vertically slidably connected in the through hole to prevent the plate from tipping over. The through hole cooperates with the wedge block, and the inclined surface of the wedge block faces the second opening. The upper surface of the wedge block is connected to the second spring, and the other end of the second spring is fixed. When the pushing part pushes the plate to move toward the loading box, when the plate contacts the wedge block, since the inclined surface of the wedge block faces the plate, the wedge block will move upward under the push of the plate, and the plate can smoothly enter the loading box. When the plate in the loading box tips over toward the second opening, due to the obstruction of the wedge block, the plate will not tip over even if it tilts, thereby not affecting the subsequent loading of the plate into the loading box.

The upper surface of the cutting knife 1 can contact the first opening, and the blade end of the cutting knife 1 is set as an inclined surface, the inclined surface faces the feed box 4, the distance difference between the cutting knife 1 and the first crossbar 8 and the second block is the total thickness of a plate and the insulating paper 3, and the distance between the cutting knife 1 and the second baffle 9 is relatively close. The first vertical rod 10 is horizontally slidably connected to the frame, and the first vertical rod 10 is driven by a driving member. The driving member in this embodiment is a second cylinder, and the piston rod of the second cylinder is fixedly connected to the two first vertical rods 10 respectively.

[0018] The stacking unit includes a third baffle plate 12, a plate loading box 13 and a pushing part, wherein the third baffle plate 12 is located below the two groups of plate packing units, the plate loading box 13 is located on the left side of the third baffle plate 12, and the pushing part is located on the right side of the third baffle plate 12. A second opening is provided on the right side of the plate loading box 13.

The two ends of the second cross bar 17 are respectively connected to the right end of the first spring 16 and the piston rod of the first cylinder 18.

[0020] A horizontal fifth baffle 19 is provided between the two fourth baffles 14, the fifth baffle 19 is fixed on the frame, the fifth baffle 19 is located below the first baffle 5, and the length of the fourth baffle 14 on the right side is less than the horizontal distance between the fourth baffle 14 and the fifth baffle 19.

[0021] A plurality of through holes are formed on the upper surface of the plate loading box 13, in which a wedge 20 is vertically slidably connected for preventing the plates from tipping over.

[0022] The specific implementation process is as follows:

[0023] The motor is turned to drive the shaft 2 to rotate, and the shaft 2 rotates to drive the insulating paper 3 to rotate until the free end of the insulating paper 3 falls to be flush with the upper surface of the first baffle 5, and the motor is stopped. The positive plate 6 and the negative plate 7 are respectively loaded into the two feed boxes 4, and a plate located at the first opening will fall from the first opening to the first baffle 5. Since the bottom surface of the feed box 4 is inclined, the next plate will fill the position and move to the first opening. Since the distance between the first baffle 5 and the first opening is just the height of a plate, the plate located on the first baffle 5 will prevent the next plate from continuing to fall, and the two plates will overlap.

[0024] Open the second cylinder, so that the piston rod of the second cylinder drives the first vertical rod 10, the cutting knife 1 and the first cross bar 8 to move to the left. When the cutting knife 1 contacts the overlapping part of the two plates, since the blade end of the cutting knife 1 is set as an inclined surface, the inclined surface will push the plate at the first opening upward, so that the cutting knife 1 can pass smoothly. At the same time, the cutting knife 1 also blocks the plate in the feed box 4, so that the plate cannot fall; when the first cross bar 8 contacts the plate, it will push the plate to move to the left. Since the distance difference between the cutting knife 1 and the first cross bar 8 and the second stopper is the total thickness of a plate and the insulating paper 3, when the cutting knife 1 cuts the insulating paper 3, the plate just contacts the insulating paper 3. Drive the second cylinder in reverse to move the cutting knife 1 and the first cross bar 8 to the right, and the plate and the cut insulating paper 3 will fall down to the third baffle 12 under the action of gravity.

[0025] The fallen insulating paper 3 will contact the fourth baffle 14, and the fourth baffle 14 can effectively prevent the fallen pole plate and insulating paper 3 from tipping to the left. At the same time, the first cylinder 18 is started, and the piston rod of the first cylinder 18 pushes the first spring 16 and the second cross bar 17 to move quickly to the left. During the movement, the two groups of insulating paper 3 and the pole plate will be pushed to move into the loading box 13. Due to the fast moving speed, the insulating paper 3 also remains in a vertical state. When the pole plate contacts the wedge block 20, since the inclined surface of the wedge block 20 faces the pole plate, the wedge block 20 will move upward under the push of the pole plate, and the pole plate can smoothly enter the loading box 13. When the pole plate in the loading box 13 is tilted toward the second opening, due to the obstruction of the wedge block 20, the pole plate will not tip over even if it tilts, thereby not affecting the subsequent loading of the pole plate into the loading box 13. During the movement, the insulating paper 3 and the pole plate will push the fourth baffle 14 to swing to the left, so that the insulating paper 3 and the pole plate can pass smoothly. The pushing part is then driven in the reverse direction to restore it to its original position. The above operations are repeated to realize the stacking and assembly of the electrode plates, and the insulating paper 3 is provided between the positive electrode plate 6 and the negative electrode plate 7 .
