[0021] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive. Example

[0022] Please refer to the attached Figure 1As shown in FIG. 8 , a battery steel shell conveying device comprises a linear conveying track 1, a material tray 2 is connected to the end of the linear conveying track 1, the material tray 2 is provided with a limit track 3, and a cleaning system 5 is provided on the limit track 3 and the linear conveying track 1; the cleaning system 5 comprises a track cleaning unit 6 and an electrostatic adsorption unit 7, the track cleaning unit 6 comprises a driving motor 601, the driving motor 601 is arranged on the top of the linear conveying track 1, and the output end of the driving motor 601 is connected to a driving gear 602, the driving gear 602 is connected to a driven gear 604 through a chain 603, and the driving gear 60 2 and the driven gear are connected with a rotating shaft 605, and a rotating cylinder 606 is sleeved on the rotating shaft 605. Multiple groups of rotating cylinders 606 are symmetrically set up on both sides of the linear conveying track 1, and the size of the rotating cylinder 606 matches the size of the battery steel shell 8. Nylon bristles are arranged on the surface of the rotating cylinder 606, which can roll and clean the waste on the surface of the battery steel shell 8 moving on the linear conveying track 1; the electrostatic adsorption unit 7 includes an electrode sheet 701, and the electrode sheet 701 is distributed in an array on the inner wall of the side of the limiting track 3 facing the material tray 2, and the electrode sheet 701 absorbs the waste remaining on the surface of the battery steel shell 8 through the principle of electrostatic adsorption.

[0023] It should be noted that the driving motor 601 serves as the power source of the track cleaning unit 6. When the driving motor 601 is started, its output shaft drives the driving gear 602 to rotate at high speed. The driving gear 602 drives the driven gear 604 to rotate synchronously through the chain 603, thereby driving the rotating shaft 605 to rotate, and then the rotating cylinder 606 mounted on the rotating shaft 605 begins to rotate. Multiple groups of rotating cylinders 606 are symmetrically distributed on both sides of the linear conveying track 1. When the battery steel shell 8 moves forward on the linear conveying track 1, the rotating cylinder 606 contacts the surface of the battery steel shell 8, and scraps attached to the surface of the steel shell are scraped off by rolling. The main body of the rotating cylinder 606 is made of lightweight and wear-resistant plastic material, which not only reduces the overall weight of the equipment, but also ensures its durability. The nylon bristles on its surface are moderately soft, which can effectively remove scraps without scratching the surface of the battery steel shell 8.

[0024] It should be noted that when the electrode sheet 701 is powered on, an electrostatic field will be formed around it. When the battery steel shell 8 passes through the limiting track 3 on the tray 2, due to electrostatic induction, the residual waste on the surface of the steel shell will be attracted by the electrostatic adsorption force generated by the electrode sheet 701. The array distribution of the electrode sheet 701 has been carefully designed to ensure that when the battery steel shell 8 passes through the limiting track 3, the fine waste that the track cleaning unit 6 has not completely cleaned can be removed, thereby completely removing the residual waste. This electrostatic adsorption method can capture extremely fine particles, further improve the cleanliness of the battery steel shell 8, and provide a guarantee for the high quality requirements of subsequent battery production.

[0025] It should be noted that a chip collecting bin 101 is provided in the linear conveying track 1. The top of the chip collecting bin 101 is an inclined slope with an inclination angle ranging from 30° to 60°, which can make the waste chips automatically slide to the bottom of the chip collecting bin 101 under the action of gravity, and a scraper 607 is provided above the chip collecting bin 101. One side of the scraper 607 is connected to the inner wall of the linear conveying track 1, and the other end is in contact with the rotating cylinder 606. The scraper 607 made of elastic engineering plastic can fit tightly to the surface of the rotating cylinder 606, scrape off the waste chips attached to the rotating cylinder 606 and make them fall into the chip collecting bin 101. The elastic design of the scraper 607 can adapt to the surface shape of the rotating cylinder 606 to ensure a close fit at all times, thereby improving the waste chip cleaning effect.

[0026] It should be noted that the chip collecting groove 301 provided at the bottom of the limiting track 3 cooperates with the dust collecting pipe 702, and the dust collecting pipe 702 is provided with a dust collecting port 703 on the side facing the chip collecting groove 301, and the position and number of the dust collecting port 703 correspond to the electrode sheet 701, so that the waste scraps adsorbed by the electrode sheet 701 can be accurately sucked out. When it is necessary to clean the waste scraps adsorbed on the electrode sheet 701, the control system controls the polarity of the electrode sheet 701 to change in the opposite direction, so as to completely peel off the adsorbed waste scraps from the surface of the electrode sheet 701. This method of cleaning the waste scraps by changing the polarity of the electrode sheet 701 is simple and efficient to operate, and can ensure that the electrode sheet 701 continues to maintain good adsorption performance. At the same time, the dust suction port 703 of the dust suction pipe 702 in the chip collecting groove 301 at the bottom of the limiting track 3, because its position and number correspond to the electrode sheet 701, can accurately suck the peeled waste chips into the dust suction pipe 702, and then enter the filter box 705 through the connecting pipe 704. The filter box 705 can separate the inhaled air and waste chips, and the waste chips are trapped in the filter box 705, while the filtered air enters the dust suction fan 707 through the connecting pipe 704 and is discharged by the dust suction fan 707 to ensure the cleanliness of the working environment.

[0027] It should be noted that the filter box 705 is a graded filtration system, which includes a coarse filter 7051, a fine filter 7052 and a fine filter 7053 in sequence. The pore size range of the coarse filter 7051 is 5-10mm, which can effectively block larger impurities and prevent them from entering the subsequent finer filtration levels, thereby extending the service life of the fine filter 7052 and the fine filter 7053; the pore size range of the fine filter 7052 is 1-5mm, which further purifies the air, intercepts medium-sized waste debris, and improves the filtration effect; the pore size range of the fine filter 7053 is 0.1-1mm, which can capture extremely small particles, ensuring that the exhausted air meets a higher cleanliness standard and meets the requirements of the production workshop for environmental cleanliness. The pore sizes of the filters at each level are arranged in descending order to gradually intercept waste debris and pollutants of different particle sizes. When the air containing waste debris enters the filter box 705, the coarse filter 7051 first intercepts the waste debris of larger particle sizes, then the fine filter 7052 filters the waste debris of medium particle sizes, and finally the fine filter 7053 captures fine pollutants, so as to achieve efficient separation of the inhaled air and waste debris. In addition, a dust collecting bin 706 is provided at the bottom of the filter box 705, and a material level sensor is provided in the dust collecting bin 706. The material level sensor can monitor the accumulation height of waste debris in the dust collecting bin 706 in real time. When the waste debris accumulates to a certain extent, the staff can be reminded to clean it up in time to avoid affecting the normal operation of the filter box 705 due to excessive waste debris, thereby ensuring the efficient and stable operation of the entire dust collecting and dust collection system.

[0028] Please refer to the attached Figure 1 , 2 As shown in FIG. 3 , 8 to 10 material placing grooves 201 are distributed in a circle on the material tray 2. The radius of the material placing groove 201 matches the radius of the battery steel shell 8. A divider 202 is provided in the center of the material tray 2. The divider 202 is used to control the intermittent rotation of the material tray 2 and accurately determine the relative position of the material groove 201.

[0029] It should be noted that the circumferentially distributed material troughs 201 on the material tray 2 can orderly receive the battery steel shells 8 transmitted from the linear conveying track 1. The radius of the material troughs 201 matches the radius of the battery steel shells 8, which can ensure that the battery steel shells 8 are accurately placed to avoid the steel shells from being offset or falling during the placement process. The number and distribution spacing of the material troughs 201 are designed according to the production rhythm and the needs of subsequent processing equipment to ensure that the arrangement of the battery steel shells 8 on the material tray 2 is both compact and convenient for subsequent process operations. The high-precision control of the divider 202 can ensure that each material trough 201 can accurately stop at a predetermined position, thereby improving the automation and production efficiency of the entire production process. Through the cooperation of the material troughs 201 and the divider 202, the battery steel shells 8 can be transported according to the preset program and rhythm. Compared with manual placement and positioning, the production speed can be greatly improved, and the error of manual operation can be reduced, which provides convenience for subsequent processing or packaging processes.

[0030] Please refer to the attached Figure 1 , 2 As shown in Figure 3, the material tray 2 is connected to a material discharge track 4, and a material discharge curved arm 401 is provided on one side of the material discharge track 4. The curvature of the material discharge curved arm 401 matches the circumference of the battery steel shell 8, and a buffer pad 402 is provided on the contact surface between the material discharge curved arm 401 and the battery steel shell 8.

[0031] It should be noted that when the material tray 2 rotates intermittently under the control of the divider 202, and the material trough 201 containing the battery steel shell 8 is rotated to the vicinity of the unloading track 4, the unloading curved arm 401 begins to play a role. Since the curvature of the unloading curved arm 401 matches the circumference of the battery steel shell 8, it can fit the outer surface of the battery steel shell 8 well. As the material tray 2 continues to rotate, the unloading curved arm 401 gradually guides the battery steel shell 8 to disengage from the material trough 201, allowing it to smoothly transition to the unloading track 4; the buffer pad 402 is made of a soft and elastic material, which effectively avoids the impact force that the battery steel shell 8 may be subjected to during the transfer process, and avoids scratches, deformation and other damage to the surface of the battery steel shell 8 due to collision, thereby ensuring the integrity of the battery steel shell 8 and improving product quality.

[0032] The specific operation process of the present invention is as follows: First, the battery steel shell 8 enters the conveying device through the linear conveying track 1, and the driving motor 601 is started, and its output shaft drives the driving gear 602 to rotate at a high speed. The driving gear 602 drives the driven gear 604 to rotate synchronously through the chain 603, so that the rotating shaft 605 rotates, and then drives the rotating cylinder 606 sleeved on the rotating shaft 605 to rotate. Multiple groups of rotating cylinders 606 are symmetrically distributed on both sides of the linear conveying track 1. When the battery steel shell 8 moves forward on the linear conveying track 1, the rotating cylinder 606 contacts the surface of the battery steel shell 8 moving forward on the linear conveying track 1, and collects the waste chips attached to the surface of the steel shell by rolling. The waste chips on the surface of the rotating cylinder 606 are scraped off by the scraper 607 that fits closely to its surface and fall into the chip collecting bin 101 in the linear conveying track 1; Then, the battery steel shell 8 is conveyed to the limiting track 3 of the material tray 2 along the linear conveying track 1. At this time, the electrode sheet 701 is powered on to form an electrostatic field around it. The waste chips remaining on the surface of the battery steel shell 8 are attracted by the electrostatic adsorption force generated by the electrode sheet 701, so as to further clean the surface of the battery steel shell 8 and remove the fine waste chips that the track cleaning unit 6 has not completely cleaned. When it is necessary to clean the waste chips adsorbed on the electrode sheet 701, the control system controls the polarity of the electrode sheet 701 to change in the reverse direction, and completely peels off the adsorbed waste chips from the surface of the electrode sheet 701. At the same time, the dust suction port 703 of the dust suction pipe 702 in the chip collecting groove 301 at the bottom of the limiting track 3 can accurately suck the peeled waste chips into the dust suction pipe 702 because of its position and number corresponding to the electrode sheet 701, and then enter the filter box 705 through the connecting pipe 704; Finally, the material tray 2 rotates intermittently under the control of the divider 202. When the material trough 201 containing the cleaned battery steel shell 8 is rotated to the vicinity of the unloading track 4, the unloading arm 401 guides the battery steel shell 8 to detach from the material trough 201 and smoothly transition to the unloading track 4. The battery steel shell 8 enters the subsequent production link along the unloading track 4.

[0033] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
