Description

Technical Field

[0001] The utility model relates to the technical field of battery recycling equipment, and in particular to a fast sorting device for retired power batteries. Background Art

[0002] Rapid sorting equipment is mainly used to improve the efficiency of sorting retired power batteries, and quickly evaluate the health status and performance indicators of batteries through appearance inspection, capacity testing, etc. The development prospects and application prospects of these devices are very broad. With the rapid expansion of the electric vehicle market, it is expected that a large number of retired power batteries will need to be processed in the future, which provides a huge market demand for rapid sorting equipment. In addition, since the performance parameters of retired batteries vary, in order to effectively utilize them for cascade utilization, the batteries must be accurately sorted to ensure that the reorganized battery pack can maintain good performance consistency.

[0003] In the prior art, retired power batteries are prone to bending or shell scratches due to mishandling or irregular operation during removal. If such damaged batteries are directly crushed or disassembled without sorting, they are prone to smoke and fire or even damage, reducing production safety. Manual sorting is more troublesome, and small-angle bends are difficult to detect. Workers need to spend a lot of time and energy on sorting, which reduces user experience, reduces work efficiency and increases labor costs, causing a significant increase in production costs. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a fast sorting device for retired power batteries.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a kind of retired power battery rapid sorting equipment, including an equipment body, a sedimentation tank is provided on the top of the equipment body, a conveyor belt is provided on the inner wall of the sedimentation tank, an induction device is fixed on the top of the equipment body, a sliding side groove is provided on the linear array of the side of the induction device, a dielectric part is fixed on the bottom of the inner wall of the sliding side groove, a fixed shaft is fixed on the inner wall of the sliding side groove, a disc part is rotatably connected to the circumference of the fixed shaft, a vortex spring is fixed on the inner wall of the disc part, one end of the vortex spring is fixed to the circumference of the fixed shaft, an arc-shaped touch key is fixed on the circumferential array of the circumference of the disc part, a dielectric rod is fixed on the circumference of the disc part, and a contact head is fixed on one end of the dielectric rod. In the prior art, retired power batteries are easily bent or their shells are scratched due to misoperation or irregular operation during removal. If such damaged batteries are directly crushed or disassembled without sorting, they are easy to smoke and catch fire or even guarantee, which reduces production safety. Manual selection is more troublesome, and small-angle bending is difficult to find, and staff need A lot of time and energy are consumed for sorting, which reduces the user experience, reduces work efficiency and increases labor costs, causing a significant increase in production costs. In response to such problems, the utility model solves the problem by installing a contact head, so that when production starts, the process equipment sends the retired power battery into the main body of the equipment, which is driven by the conveyor belt to the contact head, and the contact head contacts the top of the retired power battery. When the battery is bent or scratched, the contact head is tightly attached to the battery surface due to the influence of the vortex spring. The bending and scratching will cause the contact head to move up and down, so that the dielectric rod drives the disc to rotate, and at the same time, the arc touch key in contact with the dielectric part changes. The circuit inside the equipment will experience instantaneous current fluctuations, which are directly caused by the mechanical movement caused by the uneven surface of the battery. The sensing system of the equipment can accurately capture this current fluctuation and immediately mark the battery. This mark means that the battery has been identified as having potential appearance defects and needs to be separated or downgraded in subsequent processing, so as to perform rapid sorting and achieve the effect of improving work efficiency.

[0006] Preferably, side limit grooves are provided on both sides of the inner wall of the equipment body, and the inner wall of the side limit groove is rotatably connected to an axial rotating part, and crescent rubber pads are fixed to the four corners of the circumference of the axial rotating part. In the prior art, when a lightweight battery moves on a conveyor belt, the friction between its bottom and the conveyor belt is insufficient to overcome the resistance generated by the contact head. In particular, during inspection and sorting, the contact head needs to be close to the top of the battery to complete the electrical connection or detect appearance defects. If the friction of the conveyor belt is insufficient, the battery cannot move forward smoothly, causing stagnation, thereby affecting the operating efficiency of the entire production line. To address this problem, the utility model solves it by installing crescent rubber pads, so that when production starts, the axial rotating part rotates in the same direction as the conveyor belt. At the same time, the crescent rubber pad plays a temporary clamping function through the surface friction and the pressure applied to the side of the battery, pushing the battery forward to prevent the battery from staying, thereby improving work efficiency.

[0007] Preferably, both sides of the inner wall of the device body are provided with downward edges, and the downward edges are fixed with downward cameras in a linear array. In the prior art, the device should only mark and sort batteries that are truly defective or damaged. In actual production, some batteries, due to the uneven design of their surfaces, will cause misjudgment of the device when passing through the sorting equipment even if there is no obvious physical damage, and will make it difficult for staff to judge after confusion. To solve such problems, the utility model adopts the method of installing downward cameras to solve them, so that when the equipment determines that the battery is abnormal, the downward cameras are simultaneously started to shoot the top of the battery at a downward angle as one of the identification bases, which facilitates the staff to sort and pick, thereby improving the sorting accuracy.

[0008] Preferably, a convex push plate is fixed on the surface of the conveyor belt, which prevents the battery from stagnating after entering the equipment, thereby improving work efficiency.

[0009] Preferably, both sides of the contact head are provided with rounded edges to prevent the equipment from scratching the battery and improve production safety.

[0010] Preferably, a heat dissipation hole is opened on the front of the sensing device to improve the heat dissipation effect, maintain the circuit sensing accuracy, and improve the sorting accuracy.

[0011] Preferably, the outer end of the crescent rubber pad extends 5 mm beyond the edge of the side limit groove to ensure pressure is applied while preventing the battery from shifting or deforming due to excessive extension, thereby improving the stability of the device.

[0012] Beneficial Effects

[0013] 1. In the prior art, retired power batteries are prone to battery bending or shell scratches due to misoperation or irregular operation during removal. Such damaged batteries are prone to smoke and fire or even damage if they are directly crushed or disassembled without sorting, which reduces production safety. Manual selection is more troublesome, and small-angle bends are difficult to find. Workers need to spend a lot of time and energy on sorting, which reduces user experience and causes reduced work efficiency and increased labor costs, causing a significant increase in production costs. In response to such problems, the utility model adopts the method of installing a contact head to solve the problem, so that when production starts, the process equipment sends the retired power battery into the equipment body, which is driven by the conveyor belt to the contact head. The contact head contacts the top of the retired power battery. When the battery is bent or scratched, the contact head is pressed against the battery surface due to the influence of the vortex spring. The bending and scratching will cause the contact head to move up and down, so that the dielectric rod drives the disc to rotate, and at the same time, the arc-shaped touch key in contact with the dielectric part changes. The circuit inside the device will experience instantaneous current fluctuations. This fluctuation is directly caused by the mechanical movement caused by the uneven surface of the battery. The sensing system of the device can accurately capture this current fluctuation and immediately mark the battery. This mark means that the battery has been identified as having potential appearance defects and needs to be separated or downgraded in subsequent processing, so as to quickly sort it and achieve the effect of improving work efficiency.

[0014] 2. In the prior art, when a lightweight battery moves on a conveyor belt, the friction between its bottom and the conveyor belt is not sufficient to overcome the resistance generated by the contact head. In particular, during inspection and sorting, the contact head needs to be in close contact with the top of the battery to complete the electrical connection or detect appearance defects. If the friction of the conveyor belt is insufficient, the battery cannot move forward smoothly, causing stagnation, thereby affecting the operating efficiency of the entire production line. To address this problem, the utility model solves this problem by installing a crescent rubber pad, so that when production starts, the shaft rotating part rotates in the same direction as the conveyor belt. At the same time, the crescent rubber pad acts as a temporary clamp through the surface friction and the pressure applied to the side of the battery, pushing the battery forward to prevent the battery from staying, thereby improving work efficiency.

[0015] 3. In the prior art, the equipment should only mark and sort the batteries that are truly defective or damaged. In actual production, some batteries, due to the uneven design of their surface, will cause misjudgment of the equipment when passing through the sorting equipment even if there is no obvious physical damage, and make it difficult for the staff to judge after confusion. To solve this problem, the utility model adopts the method of installing a top-down camera to achieve a solution. When the equipment determines that the battery is abnormal, the top-down camera is simultaneously started to shoot the top of the battery at a top-down angle as one of the identification bases, which is convenient for the staff to sort and pick, thereby improving the sorting accuracy.

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0023] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:

[0025] Reference Figure 1-4A fast sorting device for retired power batteries includes a device body 1, a sedimentation tank 101 is provided on the top of the device body 1, a conveyor belt 102 is provided on the inner wall of the sedimentation tank 101, an induction device 2 is fixed on the top of the device body 1, a sliding side groove 201 is provided on the side of the induction device 2 in a linear array, a dielectric member 203 is fixed on the bottom of the inner wall of the sliding side groove 201, a fixed shaft 202 is fixed on the inner wall of the sliding side groove 201, a disc member 204 is rotatably connected to the circumference of the fixed shaft 202, a vortex spring 205 is fixed on the inner wall of the disc member 204, one end of the vortex spring 205 is connected to the fixed The circumference of the shaft 202 is fixed, and the circumference of the disc 204 is fixed with an arc-shaped touch key 206 in a circumferential array. The circumference of the disc 204 is fixed with an intermediate rod 207, and a contact head 208 is fixed at one end of the intermediate rod 207. Due to misoperation or irregular operation when removing the retired power battery, it is easy to cause the battery to bend or the shell to be scratched. If such damaged batteries are directly crushed or disassembled without sorting, it is easy to smoke and catch fire or even guarantee, which reduces production safety. It is troublesome to select manually, and small-angle bends are difficult to find, and the staff need to spend a lot of time. The time and energy required for sorting the retired power batteries is reduced, which reduces the user experience, reduces work efficiency and increases labor costs, causing a significant increase in production costs. The problem is solved by installing a contact head 208. When production starts, the process equipment sends the retired power batteries into the equipment body 1, which is driven by the conveyor belt 102 to the contact head 208. The contact head 208 contacts the top of the retired power battery. When the battery is bent or scratched, the contact head 208 is tightly attached to the battery surface due to the influence of the vortex spring 205. The bending and scratching will cause the contact head 208 to move up and down. , so that the dielectric rod 207 drives the disc 204 to rotate, and at the same time, the arc-shaped touch key 206 in contact with the dielectric 203 changes, and the circuit inside the device will experience instantaneous current fluctuations. This fluctuation is directly caused by the mechanical movement caused by the uneven surface of the battery. The sensing system of the device can accurately capture this current fluctuation and immediately mark the battery. This mark means that the battery has been identified as having potential appearance defects and needs to be separated or downgraded in subsequent processing, so as to achieve rapid sorting and improve work efficiency. A convex push plate 5 is fixed on the surface of the conveyor belt 102. The convex push plate 5 prevents the battery from stagnating after entering the device, thereby improving work efficiency. Rounded edges 209 are provided on both sides of the contact head 208 to prevent the equipment from scratching the battery and improve production safety.

[0026] Side limit grooves 3 are provided on both sides of the inner wall of the equipment body 1. The inner wall of the side limit groove 3 is rotatably connected to an axial rotating part 301. Crescent rubber pads 302 are fixed at the four corners of the circumference of the axial rotating part 301. When the lightweight battery moves on the conveyor belt 102, the friction between its bottom and the conveyor belt 102 is not enough to overcome the resistance generated by the contact head 208. In particular, during detection and sorting, the contact head 208 needs to be close to the top of the battery to complete the electrical connection or detect appearance defects. If the friction of the conveyor belt 102 is insufficient, the battery cannot move forward smoothly, causing stagnation, which in turn affects the operating efficiency of the entire production line. The problem is solved by installing crescent rubber pads 302. When production starts, the axial rotating part 301 rotates in the same direction as the conveyor belt 102. At the same time, the crescent rubber pad 302 plays a temporary clamping function through the surface friction and the pressure applied to the side of the battery, pushing the battery forward to prevent the battery from staying, thereby improving work efficiency. The outer end of the crescent rubber pad 302 exceeds the edge of the side limit groove 3 by 5 mm. While ensuring the pressure is applied, it prevents the battery from being displaced or deformed due to excessive extension, thereby improving the stability of the device. Both sides of the inner wall of the device body 1 are provided with a downward edge 4, and a downward camera 401 is fixed on the linear array of the downward edge 4. The device should only mark and sort batteries that are truly defective or damaged. In actual production, some batteries, due to the uneven design of their surfaces, even if there is no obvious physical damage, will cause misjudgment of the device when passing through the sorting device, and after confusion, it will be difficult for the staff to judge. The method of installing the downward camera 401 is used to solve this problem. When the device determines that the battery is abnormal, the downward camera 401 is simultaneously started to shoot at the top of the battery at a downward angle as one of the identification bases, which is convenient for the staff to sort and pick, thereby achieving the effect of improving the sorting accuracy. A heat dissipation hole 2010 is opened on the front of the sensing device 2 to improve the heat dissipation effect, maintain the circuit sensing accuracy, and improve the sorting accuracy.

[0027] The working principle of the utility model is as follows: when production starts, the process equipment sends the retired power battery into the equipment body 1, which is driven by the conveyor belt 102 to the contact head 208. The contact head 208 contacts the top of the retired power battery. When the battery is bent or scratched, the contact head 208 is tightly attached to the battery surface due to the influence of the vortex spring 205. The bending and scratching will cause the contact head 208 to move up and down, so that the dielectric rod 207 drives the disc part 204 to rotate, and at the same time, the arc touch key 206 in contact with the dielectric part 203 is changed, and the battery is immediately marked. When production starts, the shaft rotating part 301 rotates in the same direction as the conveyor belt 102, and at the same time, the crescent rubber pad 302 plays a short clamping function through the surface friction and the pressure applied to the side of the battery, pushing the battery forward. When the equipment determines that the battery is abnormal, the overhead camera 401 is simultaneously started to shoot the top of the battery at a downward angle as one of the identification bases.
