Description

Technical Field

[0001] This utility model relates to the technical field of automated battery cell testing equipment, specifically to an alternating platform for scanning OCV tests on blade batteries. Background Technology

[0002] In the battery cell production process, cell barcode scanning and OCV (Optical Character Verification) are both important steps in the cell production line. Barcode scanning is used to identify battery information, and OCV testing is used to test battery performance such as resistance and voltage.

[0003] For blade batteries, the terminals are mostly on both sides. During the battery production process, barcode scanning and OCV testing are relatively independent stations. Traditional methods result in a more complicated mechanism and cumbersome operation process due to the two stations involved in barcode scanning and OCV measurement, leading to low efficiency.

[0004] Traditional barcode scanning and OCV testing both require a relatively complex mechanism to scan and test the battery. For most processes, barcode scanning must be performed first, followed by OCV testing. This separates the actions, resulting in low efficiency, complex mechanisms, and high costs. Utility Model Content

[0005] The purpose of this utility model is to provide a blade battery barcode scanning OCV testing alternating platform, which aims to solve the problem of synchronizing barcode scanning and OCV testing actions when the battery cell is being loaded, to conduct uninterrupted testing, enhance the continuity of structural actions, and improve workstation efficiency.

[0006] To address this, this utility model proposes an alternating platform for OCV testing of blade batteries using barcode scanning, comprising a welding frame, a rodless sliding cylinder, a lifting cylinder, and a shuttle lifting platform; it also has three workstations: a placement position, a barcode scanning position, and a testing position. The barcode scanning position is equipped with a barcode scanning component, and the testing position is equipped with an OCV testing component. The shuttle lifting platform is clamped inside the welding frame and connected to a horizontal mounting plate via the lifting cylinder. The horizontal mounting plate is connected to the slider of the horizontally positioned rodless sliding cylinder, allowing the shuttle lifting platform to reciprocate back and forth and move up and down within the welding frame.

[0007] The shuttle lifting platform is equipped with a first clamping claw at the rear of its upper end, which moves the battery cell located at the placement position to the scanning position and scans the battery cell using the scanning component; the shuttle lifting platform is equipped with a second clamping claw at the front of its upper end, which moves the battery cell located at the scanning position to the testing position and performs OCV testing on the battery cell using the OCV testing component.

[0008] As a preferred technical solution of this application, the OCV testing component has a probe component, with one probe component set at each of the positive and negative terminals of the battery cell.

[0009] As a preferred technical solution of this application, the scanning component is mounted on a scanning support frame, and the scanning support frame has a rotation and up-down movement mechanism.

[0010] As a preferred technical solution of this application, buffer components are respectively provided at both ends of the rodless sliding cylinder.

[0011] As a preferred technical solution of this application, the welding frame is provided with a pair of secondary positioning cylinders, both of which extend along the length direction of the battery cell.

[0012] As a preferred technical solution of this application, a large-faced clamping claw is fixedly installed on the welding frame.

[0013] As a preferred technical solution of this application, the placement position and the scanning position are merged, and the scanning component is moved to the placement position. At the same time, only the second clamping claw is on the shuttle lifting platform. After the battery cell is loaded to the scanning position, the battery cell is scanned by the scanning component. Then, the second clamping claw moves the battery cell located at the scanning position to the test position, and the OCV test component is used to perform OCV test on the battery cell.

[0014] As a preferred technical solution of this application, the upper end of the welding frame is provided with support limiting block one, support limiting block two, and support limiting block three in sequence along the length direction, and they correspond to the placement position, scanning position, and testing position in sequence.

[0015] As a preferred technical solution of this application, the outer sides of the first support limiting block, the second support limiting block, and the third support limiting block are all provided with photoelectric sensors.

[0016] As a preferred technical solution of this application, the limiting distance between the first support limiting block, the second support limiting block, and the third support limiting block can be adjusted so that multiple battery cells can be placed inside each support limiting block at a time, while multiple scanning components are placed on the scanning position and multiple OCV testing components are placed on the testing position.

[0017] The blade battery scanning OCV testing alternating platform provided by this utility model ensures that scanning and testing are carried out simultaneously through the alternating operation of the mechanism, merging the action rhythm and improving action efficiency; by using the alternating form, the battery cell is continuously scanned and tested, improving stability and enhancing efficiency; by using a cylinder structure, structural costs are reduced and the efficiency of the mechanism is improved.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-4 As shown, the blade battery scanning OCV test alternating platform of this utility model includes a welding frame 7, a rodless sliding cylinder 12, a lifting cylinder 13, and a shuttle lifting platform 1; the rodless sliding cylinder 12 and the lifting cylinder 13 drive the shuttle lifting platform 1 to reciprocate back and forth and move up and down inside the welding frame 7.

[0027] The shuttle lifting platform 1 is clamped inside the welding frame 7 and is connected to the horizontal mounting plate 14 via a lifting cylinder 13. The horizontal mounting plate 14 is connected to the slider of the horizontally positioned rodless sliding cylinder 12, allowing the shuttle lifting platform 1 to reciprocate back and forth and move up and down inside the welding frame 7. Buffer components 11 are provided at both ends of the rodless sliding cylinder 12 to ensure smooth positioning of the slide.

[0028] Among them, a clamping claw 17 is set on the rear side of the upper end of the shuttle lifting platform 1 to move the battery cell at the placement position 20 to the scanning position 30 and scan the battery cell through the scanning component 5; a clamping claw 2 is set on the front side of the upper end of the shuttle lifting platform 1 to move the battery cell at the scanning position 30 to the testing position 40 and perform OCV testing on the battery cell through the OCV testing component 4.

[0029] The blade battery scanning OCV testing alternating platform of this utility model is set with three stations: placement station 20, scanning station 30, and testing station 40. Support limiting blocks 1 8, 2 18, and 3 19 are set on both sides of the upper end of the welding frame 7 along the length direction, corresponding to placement station 20, scanning station 30, and testing station 40 respectively. Furthermore, each of the three support limiting blocks is equipped with a photoelectric sensor 9 for detecting the presence or absence of the battery.

[0030] Among them, the outer side of the support limiting block 2 18 on the right is provided with a barcode scanning component 5. The barcode scanning component 5 is installed on the barcode scanning support frame 6. The barcode scanning component 5 is used for battery barcode scanning. The barcode scanning support frame 6 has a rotation and up-down movement mechanism for adjusting the position of the barcode scanning component 5. Therefore, the barcode scanning position 30 is mainly used for battery cell barcode scanning.

[0031] Test position 40 is mainly used for cell OCV testing. Therefore, an OCV testing component 4 is fixedly installed on the upper end of the welding frame 7 where test position 40 is located. The OCV testing component 4 is located outside the support limiting block 3 19 on the right side. In order to keep the cell position stable during the test, secondary positioning cylinders 15 extending in the left and right directions are respectively set on the outside of the two support limiting blocks 3 19 and fixed on the welding frame 7 to achieve positioning in the length direction of the cell. At the same time, a large-faced clamping claw 3 is installed on the inner side of one support limiting block 3 19 and fixedly connected to the welding frame 7 to clamp and fix the cell in the thickness direction, providing stability for the test. Among them, the OCV testing component 4 has a probe component 16. One probe component 16 is set at each of the positive and negative terminals of the cell to form a circuit for OCV testing (battery electrical performance testing).

[0032] It should be noted that the limiting distance between the support limiting block 1 8, support limiting block 2 18, and support limiting block 3 19 in the blade battery scanning OCV test alternation platform of this utility model can be adjusted, allowing one or more battery cells to be placed at a time. At the same time, one or more scanning components 5 on the scanning position 30 and one or more OCV test components 4 on the test position 40 are placed, so that multiple battery cells perform synchronous alternation actions each time during the entire working process of the test alternation platform.

[0033] To achieve the lifting and reciprocating motion of the shuttle lifting platform, other different structures can be used. A multi-link structure can be used to replace the rodless sliding cylinder 12 and the lifting cylinder 13, and the alternating motion can be achieved by using a multi-link structure.

[0034] In addition, by moving the barcode scanning component 5 to the placement position 20 and merging the placement position and the barcode scanning position, the shuttle lifting platform 1 can hold only the second gripper 2, achieving a single alternating action, which can also meet the battery barcode scanning OCV test requirements. This solution reduces the number of parts in the entire device, reduces the number of process steps, improves work efficiency, and can also reduce manufacturing and operating costs.

[0035] The working principle and process of the blade battery barcode scanning OCV testing alternating platform of this utility model are briefly described below.

[0036] First, a robotic arm or a three-axis robot picks up the battery cell and places it on the support limit block 8 at the placement position 20; the battery cell is stuck between the support limit blocks 8 and is detected in place by the photoelectric sensor 9, and then the lifting cylinder 13 lifts the battery cell up.

[0037] Then, clamping jaw 17 holds the battery cell (ensuring cell stability during movement); rodless sliding cylinder 12 moves the battery cell from placement position 20 to scanning position 30, where the battery cell is stuck between support limit blocks 18, and clamping jaw 17 releases the battery cell; lifting cylinder 13 then descends; rodless sliding cylinder 12 moves shuttle lifting platform 1 to placement position 20; scanning component 5 scans the battery cell;

[0038] Then, the lifting cylinder 13 lifts up again, simultaneously lifting the battery cells placed at the placement position 20 and the scanning position 30; clamping jaw 17 clamps the battery cell at the placement position 20, and clamping jaw 2 clamps the battery cell at the scanning position 30; the rodless sliding cylinder 12 slides into place; the lifting cylinder 13 lowers, the battery cell at the placement position 20 moves to the scanning position 30 and is lowered, and the battery cell at the scanning position 30 moves to the testing position 40 and is lowered.

[0039] Finally, the cylinders holding gripper 17 and gripper 2 are released, the lifting cylinder 13 falls, and the rodless sliding cylinder 12 returns to its original position; the barcode scanning position 30 performs barcode scanning; the secondary positioning cylinder 15 of the test position 40 positions the battery cell, the large-face gripper 3 clamps the battery cell securely, and the OCV test component 4 performs battery cell testing; the slide table performs alternating synchronous actions in sequence.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
