[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The embodiment of the present application provides a battery production line system, which can realize the simultaneous or independent lifting of batteries in a battery tray, allowing a sorting robot to pick out any batteries that do not meet the standards in any individually lifted row, and after the battery pack is loaded and before entering the next process, a strict "anti-error safety protection line" is added to automatically intercept and select defective batteries.

[0040] like Figure 1 , Figure 2 and Figure 3As shown, the present application embodiment is a battery production line system, which may include: a tray support frame 1, two groups of unilateral lifting mechanisms 3 are arranged at the bottom of the tray support frame 1, and a battery tray 2 is arranged at the top thereof, and the unilateral lifting mechanism 3 can lift a row of batteries in the battery tray 2 alone; a sorting robot 4, the sorting robot 4 is used to grab the lifted batteries, and the sorting robot 4 is equipped with a code scanning anti-fool camera; an MES system, and the MES system is connected to the unilateral lifting mechanism 3, the sorting robot 4 and the code scanning anti-fool camera. Exemplarily, the tray support frame 1 can be provided with two rows, each row has four, and the sorting robot 4 is located between the two rows of tray support frames 1, and grabs two rows of batteries in the battery tray 2 on the tray support frame 1. There are four groups of battery trays 2 on the tray support frame 1, and eight groups of unilateral lifting mechanisms 3 are correspondingly arranged below the tray support frame 1, and every two groups of unilateral lifting mechanisms 3 correspond to one group of battery trays 2, and each unilateral lifting mechanism 3 can realize the jacking of a row of batteries in the battery tray 2 alone. Among them, the MES system, namely the Manufacturing Execution System, is an intermediate software system located between the enterprise planning system (such as ERP / SCM) and the process control system (such as PCS). It aims to strengthen the execution function of the MRP (Material Requirements Planning) plan and optimize the management of the entire production process from order placement to product completion through information transmission. The connection between the MES system and the unilateral lifting mechanism 3, the sorting robot 4 and the code scanning anti-fool camera can be a network cable connection, Bluetooth connection, WIFI connection or other communication connection methods.

[0041] Specifically, first, by using two sets of unilateral lifting mechanisms 3, the batteries in the battery tray 2 can be lifted at the same time. When descending, one side will descend before the other side. It can also realize the independent lifting of two rows of batteries, allowing the sorting robot 4 to select any battery that does not meet the standards in any row that is lifted separately for separate processing. Second, the sorting robot 4 adds a code scanning anti-fool camera, which adds a strict "anti-error safety protection line" after the battery pack is loaded and before entering the next process. The barcode information of any battery in the battery tray 2 can be scanned by the code scanning anti-fool camera. Subsequently, the sorting robot 4 compares and verifies the collected data (including gear level, voltage / current / internal resistance value, Mark, model, etc.) with the preset data in the MES system. If the comparison result is confirmed to be correct, the battery pack will continue to flow normally to the next process. However, if the data comparison shows an abnormality, the robot will automatically intercept and select the bad battery, and simultaneously record the battery's bad information, cause, status, time and other related data. This record facilitates subsequent manual intervention analysis and processing, effectively improving the efficiency and accuracy of quality control in the production process.

[0042] In one embodiment, if Figure 2 As shown, the unilateral lifting mechanism 3 may include: a ground fixing plate 301, a telescopic cylinder 1 302 is installed on the ground fixing plate 301, a lifting plate 303 is fixed to the telescopic end of the telescopic cylinder 1 302, and two rows of telescopic cylinders 2 304 are fixed to the lifting plate 303; when the telescopic cylinder 1 302 extends to drive the lifting plate 303 to rise, the lifting plate 303 pushes the two rows of telescopic cylinders 2 304 to lift a row of batteries. Exemplarily, the ground fixing plate 301 can be fixed to the ground by four fixing bolts, and the telescopic cylinder 1 302 is installed on the top surface of the ground fixing plate 301 and is located between the four fixing bolts. The telescopic end of the telescopic cylinder 1 302 is extended in the up and down directions and is fixed with a lifting plate 303. The extension of the telescopic cylinder 1 302 drives the two rows of telescopic cylinders 2 304 on the lifting plate 303 to move upward, thereby individually ejecting one row of batteries in the battery tray 2. When the sorting robot 4 identifies a non-standard battery in a row to be individually ejected, the two telescopic cylinders 2 304 in the row below the non-standard battery are individually lifted again, so that the subsequent sorting robot 4 can grab the non-standard battery for transportation.

[0043] In one embodiment, if Figure 2 As shown, the unilateral lifting mechanism 3 may also include: two limiting rods 305, the limiting rods 305 are fixed to the ground fixing plate 301, and the length direction of the limiting rods 305 is consistent with the extension direction of the telescopic cylinder 302; two sleeves 306, the sleeves 306 are fixed to the lifting plate 303, and the sleeves 306 are slidably connected with the corresponding limiting rods 305. Exemplarily, the limiting rods 305 are fixed at both the left and right ends of the ground fixing plate 301, and the left and right ends of the lifting plate 303 are provided with mounting holes 1, and the sleeves 306 are fixed in the mounting holes 1, and the sleeves 306 are slidably sleeved on the outer wall of the limiting rods 305. In the process of the telescopic cylinder 302 extending and retracting up and down, the limiting rods 305 and the sleeves 306 start the limiting work in the vertical direction to ensure the stability and reliability of the telescopic cylinder 302 extending and retracting up and down.

[0044] In one embodiment, if Figure 2As shown, the unilateral lifting mechanism 3 can also include: a cylinder fixing plate 307, the cylinder fixing plate 307 is fixed to the telescopic cylinder 1 302, and the cylinder fixing plate 307 is fixed with a sleeve 2 308; a limiting rod 2 309, the limiting rod 2 309 is slidably connected in the sleeve 2 308, and one end of the limiting rod 2 309 is fixed to the lifting plate 303; a threaded rod 310, the threaded rod 310 is threadedly connected to the cylinder fixing plate 307, and the threaded rod 310 can be rotated closer to or away from the lifting plate 303. Exemplarily, the cylinder body of the telescopic cylinder 302 is fixed with a cylinder fixing plate 307, and the left and right ends of the cylinder fixing plate 307 are similarly provided with mounting holes 2, and sleeves 2 308 are fixed in the mounting holes 2. Two limit rods 2 309 are fixed to the bottom surface of the lifting plate 303, and the limit rods 2 309 are slidably connected with the corresponding sleeves 2 308, which can further improve the stability and reliability of the telescopic cylinder 302 in telescopic movement up and down; wherein, the threaded rod 310 can adjust the distance between its own top end and the lifting plate 303 by rotating the thread, so as to limit the descending stroke of the lifting plate 303. When the telescopic cylinder 302 is not used for a long time, the lifting plate 303 descends to the point where the threaded rod 310 is offset, which can support the lifting plate 303 and prevent the telescopic cylinder 302 from being damaged by the weight of the lifting plate 303, the telescopic cylinder 2 304 and the sleeve 1 306.

[0045] In one embodiment, if Figure 3 As shown, the tray support frame 1 is fixed with a side positioning cylinder 101 and a side positioning plate 102; the side positioning cylinder 101 can push the battery tray 2 against the side positioning plate 102 to position the battery tray 2 sideways. Exemplarily, the side positioning cylinder 101 is installed on the front side of the top surface of the tray support frame 1, and the extension direction of the side positioning cylinder 101 is the front-to-back direction. The side positioning plate 102 is fixed on the rear side of the top surface of the tray support frame 1. When the side positioning cylinder 101 is extended, it can push the side of the battery tray 2 against the side positioning plate 102 to achieve the side positioning of the battery tray 2.

[0046] In one embodiment, if Figure 3 As shown, the tray support frame 1 is installed with a conveyor belt 103 and fixed with an end surface positioning plate 104; the conveyor belt 103 can convey the battery tray 2 to abut against the end surface positioning plate 104 to position the end surface of the battery tray 2. The conveyor belt 103 realizes the transportation of the battery tray 2. During the transportation process, the right end surface of the battery tray 2 abuts against the end surface positioning plate 104 to realize the end surface positioning of the battery tray 2.

[0047] In one embodiment, the battery gripper of the sorting robot 4 is equipped with a protective grating sensor; when the protective grating sensor detects the presence of material under the battery gripper, the sorting robot 4 stops the battery lowering action. When the protective grating sensor can detect the presence of material under the battery gripper, the sorting robot 4 immediately stops the battery lowering action to prevent damage to the battery gripper, thus playing a protective role.

[0048] In one embodiment, the sorting robot 4 is equipped with an audible and visual alarm device; when the protective grating sensor detects that there is material under the battery clamp, the sorting robot 4 stops the battery lowering action and controls the audible and visual alarm device to alarm. Once the battery clamp finds that there is material under the battery clamp, the sorting robot 4 will immediately stop the battery lowering action and quickly trigger the audible and visual alarm device. This rapid response mechanism ensures that the battery will not continue to be pressed down, thereby avoiding possible collision and damage.

[0049] In one embodiment, the battery gripper of the sorting robot 4 is equipped with a protective optical magnetic proximity sensor; when the battery gripper is interfered by a hard object or the protective grating sensor misses a judgment, the sorting robot 4 stops the battery lowering action and controls the battery gripper to move up. In addition to the primary protective grating sensor, a second anti-collision flexible alarm device is also equipped. When the battery gripper is interfered by a hard object or a judgment is missed, the protective optical magnetic proximity sensor will immediately trigger an alarm, synchronously stop the battery lowering, and quickly lift the battery gripper. This dual protection mechanism greatly enhances safety and reliability.

[0050] In one embodiment, if Figure 1 As shown, the battery production line system further includes a battery lateral loading device 5, which is used to feed the battery tray 2. The battery lateral loading device 5 can feed the battery tray 2.
