Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a production system for protective covers for automotive battery cells. Background Technology

[0002] Automotive batteries are an essential component of automobiles. With the rapid development of automotive technology, automotive batteries have also developed rapidly, leading to a surge in demand for battery cell protection covers. The production and assembly of these covers typically involves steps such as wiring harness continuity testing, wiring harness connector assembly, film application, airtightness testing, and marking. In existing technologies, most of these steps rely heavily on manual labor, resulting in low production efficiency. For example, the wiring harness continuity testing typically involves manually checking the continuity of the wiring harness connectors using a multimeter; in the film application stage, the protective film is manually cut and then pasted onto the cell protection cover, a process that is time-consuming, results in inconsistent film lengths, and introduces errors in the placement of the film on the cell protection cover.

The second workbench 611 is used to place the protective cover body 91 equipped with the wire harness connector 93. The third moving mechanism 63, the fourth moving mechanism, and the third clamping mechanism 65 are all located on the second workbench 611. On the workbench 611, the third clamping mechanism 65 is used to clamp or loosen the protective cover body 91 and the wire harness connector 93 on the second workbench 611. The second wire harness continuity tester 64 is electrically connected to the third test head 641 and the fourth test head (not shown in the figure). The third moving mechanism 63 is used to drive the third test head 641 to move horizontally so that the third test head 641 mates with the male end of the wire harness connector 93. The fourth moving mechanism is used to drive the fourth test head to move horizontally so that the fourth test head mates with the female end of the wire harness connector 93.

[0093] Specifically, the third moving mechanism 63 includes a third guide rail 631, a third slide block 632, and a third telescopic cylinder 633.

[0100] During testing, the battery cell protection cover 9 is placed on the test bench 62, with one of the third clamping connectors 653 aligned with the cover body 91 and the other third clamping connector 653 aligned with the wiring harness connector 93 inside the cover body 91. The operator presses the third operation button 67, and the two third clamping cylinders 652 drive the two third clamping connectors 653 downwards until the cover body 91 and the wiring harness connector 93 inside are clamped. The third moving mechanism 63 drives the third test head 641 to move horizontally until the male end of the wiring harness connector 93 is aligned with the third test head 641. The fourth moving mechanism drives the fourth test head to move horizontally until the female end of the wiring harness connector 93 is aligned with the fourth test head. Then, the first wiring harness continuity tester 25 is started to perform the wiring harness continuity test.

[0101] After the test is completed, the third clamping mechanism 65, the third moving mechanism 63, and the fourth moving mechanism are reset by the second controller. When the second wire harness continuity tester 64 detects a defective wire harness connector, the operator can put the defective cell protection cover into the third defective product collection cabinet 612; when the second wire harness continuity tester 64 detects a good wire harness connector, the operator will put the good cell protection cover into the area where the airtightness tester 6 is located.

[0102] In one implementation, such as Figures 12-14As shown, the airtightness testing machine 7 includes a third frame 71, a lifting mechanism 72, a test chamber 73, a moving platform 74, an airtightness tester (not shown in the figure), and a second display screen 75.

The test chamber 73 is mounted on the lifting mechanism 72 and is located above the moving platform 74. The lifting mechanism 72 is used to move the test chamber 73 vertically. The moving platform 74 is used to place the protective cover of the battery cell under test and move the protective cover of the battery cell under test horizontally. The test chamber 73 is connected to the airtightness testing machine through a connecting pipe (not shown in the figure). A pressure sensor (not shown in the figure) is installed inside the test chamber 73. A control valve (not shown in the figure) is installed on the connecting pipe. The pressure sensor is electrically connected to the second display screen 75.

[0103] Specifically, the lifting mechanism 72 includes a column 721, a mounting plate 722, a lifting seat 723, and a hydraulic cylinder 724. The column 721 is mounted on the test platform 711, the mounting plate 722 is mounted on top of the column 721, and the lifting seat 723 is located below the mounting plate 722.

[0105] Specifically, the mobile platform 74 includes a fourth guide rail 741, a sample stage 742, and a fourth telescopic cylinder 743. The fourth guide rail 741 is located on the test platform 711, and a fourth slide (not shown in the figure) is provided on the fourth guide rail 741. The fourth slide is slidably engaged with the fourth guide rail 741. The sample stage 742 is provided on the fourth slide. The test platform 711 is provided with a through groove 7111. The fourth telescopic cylinder 743 is installed below the test platform 711. The telescopic rod of the fourth telescopic cylinder 743 is connected to a push block (not shown in the figure). The push block passes through the through groove 7111 and is connected to the sample stage 742.

[0106] The sample stage 742 is equipped with a sample slot 7421 adapted to the battery cell protection cover 9. Four support columns 7422 are installed within the sample slot 7421, each corresponding to one of the four corners of the battery cell protection cover 9. The height of the support columns 7422 is the same as the depth of the battery cell protection cover 9. The support columns 7422 provide stable support, ensuring a balanced load distribution on the battery cell protection cover 9 during airtightness testing, thereby preventing deformation of the battery cell protection cover 9 structure.

[0107] The sample stage 742 is also equipped with a positioning cylinder 745 corresponding to the sample slot 7421. The telescopic rod of the positioning cylinder 745 is adapted to the interface on the battery cell protection cover 9. The positioning cylinder 745 is used for positioning and docking with the battery cell protection cover 9.

[0108] In this application, the number of sample slots 7421 and test chambers 73 are the same and correspond one-to-one. For example, the number of sample slots 7421 on the sample stage 742 can be one, two, three or four.

[0109] The number of fourth guide rails 741 is no less than two. For example, the number of fourth guide rails 741 is three, and the three fourth guide rails 741 are evenly distributed.

[0110] The fourth guide rail 741 has guide rail seats 744 at both ends, and the guide rail seats 744 are mounted on the test platform 711.

[0111] Specifically, a test cabinet 712 is installed on the third frame 71, and the airtightness tester is installed inside the test cabinet 712. A fourth defective product collection cabinet 713 is also installed on the third frame 71. A fifth caster 714 is installed at the bottom of the third frame 71, which allows operators to easily move and change the position of the airtightness tester 7 when it is placed in the workshop.

[0112] Specifically, the airtightness testing machine 7 also includes a third controller (not shown in the figure) and a fourth operation button 76. The second display screen 75 is set on the third frame 71, and the fourth operation button 76 is set on the test platform 711. The fourth telescopic cylinder 743, the positioning cylinder 745, the airtightness testing machine, the second display screen 75, the control valve, and the fourth operation button 76 are electrically connected to the third controller.

[0113] During testing, the battery cell protection cover 9 is placed in the sample tray 7421 with the wire harness connector facing down, and the interface of the battery cell protection cover 9 is aligned with the positioning cylinder 745. The telescopic rod of the positioning cylinder 745 extends and inserts into the interface of the battery cell protection cover 9. Then, the fourth telescopic cylinder 743 is activated. Driven by the fourth telescopic cylinder 743, the sample tray 742 moves along the fourth guide rail 741 until the battery cell protection cover 9 on the sample tray 742 moves to the position corresponding to the test chamber 73. The lifting seat 72 is then driven by the hydraulic cylinder 724. 3 and test chamber 73 move downwards until test chamber 73 abuts against cell protection cover 9. Test chamber 73 and cell protection cover 9 combine to form a cavity. Then, the fourth operation button 76 is turned on. The air tightness tester inflates the corresponding cavity through the connecting pipe. The pressure sensor detects the pressure information of the corresponding cavity. When the detected pressure reaches the set value, inflation stops. Then, within the set time, the pressure sensor continues to monitor the pressure information in the cavity. If the pressure in the cavity decreases within the set range, it indicates that the cell protection cover 9 has passed the air tightness test.

[0114] This application provides a positioning cylinder 745 on the sample stage 742 that corresponds one-to-one with the sample slot 7421. The telescopic rod of the positioning cylinder 745 is designed to be compatible with the interface of the battery cell protection cover 9 itself. This allows the positioning cylinder 745 to automatically position the battery cell protection cover, ensuring that the initial position of the battery cell protection cover in the sample slot 7421 is accurate. The positioning cylinder 745, together with the support column 7422, can prevent the battery cell protection cover 9 from shifting or tilting during the pressing down of the test chamber, thereby improving the accuracy of the airtightness test.

[0115] After the test is completed, the hydraulic cylinder 724, the fourth telescopic cylinder 741, and the positioning cylinder 745 are reset sequentially by the third controller. If the airtightness test of the battery cell protection cover 9 fails, the operator can put the battery cell protection cover 9 into the fourth defective product collection cabinet 713; if the airtightness test of the battery cell protection cover 9 passes, the operator will send the battery cell protection cover 9 to the area where the laser standardization machine 8 is located.

[0116] In one implementation, such as Figure 14 As shown, the laser marking machine 8 includes a fourth frame 81, a marking operation table 82, and a laser head 83. The marking operation table 82 is located inside the fourth frame 81, and a bracket 84 is provided on the marking operation table 82. The laser head 83 is located on the bracket 84.

[0117] Specifically, the laser marking machine 8 also includes a laser operation computer 85, which is electrically connected to the laser head 83.

[0118] Specifically, the laser marking machine 8 also includes an air intake and filtering mechanism 86, which includes an air extractor 861, an air intake hood 862, and a filter 864. One end of the air extractor 861 is connected to the air intake hood 862 through an air intake pipe 863, and the other end of the air extractor 861 is connected to the filter 864 through an air supply pipe (not shown in the figure).

[0119] Specifically, the suction hood 862 is located below the laser head 83 and tilted towards the sample placement area of ​​the marking operation table 82.

[0120] During operation, the battery cell protection cover 9 is placed in the sample placement area of ​​the marking operation table 82, and the laser head 83 marks the battery cell protection cover 9 (e.g., QR code). During this process, the battery cell protection cover 9 body (injection molded part) generates harmful gases, which are absorbed and filtered out by the gas suction and filtration mechanism 86.
