[0003] At present, when the automated equipment is running, the top tooth grooves need to match the thickness of the battery cells to regularize the battery cells. The width of the grooves on both sides of the top teeth is narrow, which makes it very easy for the battery cells to retain decrystalline particles and fragments. The top tooth grooves are not equipped with an automatic cleaning function by the factory, which can easily cause a large amount of debris during long-term operation. The equipment can only be shut down regularly for manual cleaning, which is time-consuming and labor-intensive. Utility Model Content

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] See Figure 1-4 As shown in the figure, the top gear mechanism operates as follows: When the battery cells are transferred to the straightening station during machine operation, the top gear base and top gears rise to a higher position to straighten the battery cells. After straightening, the top gear base descends to a lower position for 20 seconds, waits for the next batch of battery cells to arrive, and then rises again to straighten the cells. The drive motor within the top gear mechanism drives the top gear base 6, which in turn moves the top gear fixed to it up and down.

[0029] This embodiment provides an automatic top tooth cleaning device based on the regularity of battery cells. The automatic cleaning control device is used to blow and clean the gaps on both sides of the top teeth of the top tooth mechanism, and is arranged at the middle position of the top teeth of the top tooth mechanism; the automatic cleaning control device includes a nitrogen supply device, an air knife 1, an air knife bracket 4, a proximity sensor 7, a sensor bracket, an air pipe line 3, an electromagnetic valve 10, and a throttle valve 9. The air knife 1 is used to blow and clean the gaps on both sides of the top teeth. The air knife bracket 4 and the air knife 1 are fixed by bolts; the proximity sensor 7 is fixed to the sensor bracket by bolts and locked on the air knife bracket 4; the nitrogen supply device is connected to the air knife 1 through the air pipe line 3; the air inlet end of the electromagnetic valve 10 is connected to the nitrogen supply device, and the air outlet end is connected to the air knife 1. The electromagnetic valve 10 is used to control the on-off of the nitrogen gas path; the throttle valve 9 is arranged on the main line of the air pipe line 3 to adjust the nitrogen flow rate of the ion air knife.

[0030] Specifically, in this embodiment, the wind knife bracket 4 is symmetrically arranged about the center line of the top tooth base 6; the wind knife bracket 4 is divided into three parts, the first part is a horizontal bracket for installing the wind knife 1, the second part is a left vertical bracket installed at the left end of the horizontal bracket, and the third part is a right vertical bracket installed on the right side of the horizontal bracket.

[0031] Specifically, in this embodiment, the sensor bracket is fixed on the right vertical bracket when the top gear base 6 is lowered to the lowest position, and the proximity sensor 7 is connected to the solenoid valve 10.

[0032] Specifically, in this embodiment, the proximity sensor 7 is 3-5 mm close to the bottom edge of the top tooth.

[0033] In this embodiment, the proximity sensor is fixed on the sensor bracket and is installed as a whole on the right side of the top gear base when it drops to the lowest position, 3-5 mm away from the bottom edge of the top gear. The sensor power cord is connected to the dual-core extension power cord and connected to the machine's 24V power module. When the top gear base drops to the lowest position, the proximity sensor senses the top gear base and outputs a high-level signal to the solenoid valve.

[0034] Specifically, in this embodiment, two rows of air knife holes 2 are symmetrically arranged on the air knife 1. The air knife holes 2 are located at the top tooth gaps of the top tooth grooves 8, and the air knife holes 2 are circular holes.

[0035] In this embodiment, the air knife is fixed on the air knife bracket and is installed as a whole in the middle part of the top tooth mechanism without interfering with the up and down movement of the top tooth. The air knife has multiple air holes arranged equidistantly with the top tooth grooves for blowing and cleaning the top tooth grooves on both sides.

[0036] Specifically, in this embodiment, a portion of the air pipe 3 is fixed on the left vertical bracket, and the solenoid valve 10 is installed on the left side of the top gear and does not interfere with the operation of the machine.

[0037] In this embodiment, the solenoid valve is mounted on the left side of the top gear, in a position that does not interfere with machine operation. The solenoid valve power cable is connected to the proximity sensor signal output cable. The solenoid valve's air inlet is connected to the outlet of a centralized nitrogen (5N) supply pipeline, and the air outlet is connected to an air knife.

[0038] Specifically, in this embodiment, the throttle valve 9 is connected to a throttle valve knob, and the throttle valve knob is used to adjust the opening of the throttle valve 9.

[0039] Specifically, in this embodiment, the air knife 1 is made of aluminum alloy.

[0040] In this embodiment, the operating principle of the automatic top tooth cleaning device is as follows: when the top tooth base 6 drops to the lowest position, the proximity sensor 7 senses the position and outputs a high-level signal to the solenoid valve 10. The solenoid valve 10 is energized and operates, opening the valve to transport the nitrogen from the nitrogen supply equipment to the air knife. A throttle valve 9 is installed on the air pipe 3 to control the nitrogen flow rate. The air knife blows the top tooth groove 8 through the equally spaced air knife holes. The air knife blowing process lasts for about 20 seconds, that is, the waiting time for the top tooth base to drop to the low position, to ensure that the top tooth groove 8 is in a clean and residue-free state before each rise to the high position, thereby preventing subsequent continuous debris. After installation, adjust the throttle valve knob to control the blowing size for the first time to confirm that the blowing effect is met, and no adjustment is required subsequently. When the top tooth base 6 rises and leaves the sensor detection point, the proximity sensor 7 has no sensing and no signal output, and the solenoid valve 10 loses power, closing the valve, and the air knife 1 stops blowing without nitrogen. This cycle repeats itself, and when the top gear base 6 drops to a low position, it automatically purges the top gear groove 8, and when it rises to a high position for regular correction, it automatically stops.

[0041] This embodiment realizes automatic control by adding sensors, solenoid valves and air knives. When the top tooth base drops to a low position, the air knife is automatically controlled to continuously blow and clean the top tooth grooves on both sides. When the top tooth base rises to a high position to regularize the battery cells, the blowing stops automatically. This eliminates the need to stop the machine for manual cleaning, reducing the safety hazards when manual cleaning is performed, and can realize intelligent blowing when the top tooth is in a low position and is unloaded, thereby achieving efficient processing of products.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
