Description

Technical Field

[0001] This utility model relates to the field of lithium battery equipment testing technology, and specifically to a three-coordinate measuring machine (CCM) support for lithium battery equipment. Background Technology

[0002] Lithium battery equipment testing, through the use of advanced testing technologies and equipment, such as high-precision optical testing equipment and automated testing systems, can accurately detect defects on the surface and inside of lithium battery equipment, improve the accuracy and reliability of testing, and prevent defective lithium battery equipment from entering subsequent production stages or the market, thereby reducing the generation of defective products and lowering quality costs.

[0003] According to the publicly available announcement (CN217901579U), a rapid collection device for lithium battery surface defects is disclosed. This technology includes "a first mounting plate located at the lower inner end of both a first support rod and a second support rod, with symmetrical mounting holes in the two mounting plates; a first sliding groove located on the inner side of both the first and second support rods; a first slider movably connected to each of the two first sliding grooves; and a scanning plate located between the two first sliders." This rapid collection device for lithium battery surface defects allows for easy adjustment of the distance between the scanning plate and the first and second support rods, and the first and second sliders can be adjusted for vertical sliding height. This technical solution addresses the problem of insufficient scanning in existing lithium battery surface defect collection devices, which leads to some defects not being detected in a timely manner, affecting equipment use and after-sales service.

[0004] However, in the aforementioned comparative documents, the scanning plate of this structure can only scan one plane. Defects on the surface of lithium battery devices may exist in multiple locations, which means that the detection scheme mentioned above will result in defects at certain angles not being detected, thus affecting the comprehensiveness of the detection, making it impossible to accurately locate the defect, and leading to missed detections or misjudgments.

[0005] To address the aforementioned issues, this application proposes a coordinate measuring machine (CMM) support for lithium battery equipment. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a three-coordinate measuring machine bracket for lithium battery equipment.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A three-coordinate measuring machine bracket for lithium battery equipment includes a base, a platform rotatably connected to the upper part of the base, a side frame fixedly connected to the upper part of the base, a first motor fixedly connected inside the side frame, a bidirectional lead screw fixedly connected to the output end of the first motor, the end of the bidirectional lead screw rotatably connected to the side frame, a detection mechanism provided at the side end of the side frame, a second motor fixedly connected inside the base, a positioning mechanism provided at the side end of the side frame, and a flexible clamping mechanism provided at the side end of the positioning mechanism.

[0008] The positioning mechanism includes a second slide table slidably connected inside the side frame. The inner wall of the second slide table is threadedly connected to a bidirectional lead screw. A turntable is fixedly connected to the side end of the second slide table. The mechanism is designed so that the rotation of the bidirectional lead screw can drive the turntable to rise and fall.

[0009] The output end of the second motor is fixedly connected to a rotating rod, and a rotating groove is opened on the surface of the rotating rod. The rotating rod is slidably connected to a drive bevel gear through the rotating groove. The rotating rod is configured to drive the drive bevel gear to rotate when it rotates.

[0010] The bottom end of the driving bevel gear is rotatably connected to the turntable, and the inner wall of the turntable is rotatably connected to the driven bevel gear. The surface of the driving bevel gear meshes with the driven bevel gear. The side end of the turntable is rotatably connected to the clamping platform, and the side end of the driven bevel gear is fixedly connected to the clamping platform. By setting it up, the rotation of the driving bevel gear can drive the lithium battery device on the clamping platform to rotate.

[0011] The testing mechanism includes a first slide table slidably connected inside the side frame. The inner wall of the first slide table is threadedly connected to a bidirectional lead screw. A testing frame is fixedly connected to the side end of the first slide table. An infrared scanning lamp is provided at the bottom end of the testing frame. The bidirectional lead screw can be rotated to drive the testing frame to rise and fall, thereby testing the lithium battery device through the infrared scanning lamp.

[0012] The flexible clamping mechanism includes an air pump fixedly connected to the side of the base. The output end of the air pump is connected to the clamping platform. An air chamber is opened inside the clamping platform, and a sliding groove is opened inside the clamping platform. A piston is slidably connected to the clamping platform through the sliding groove. A sliding column is fixedly connected to the side end of the piston, and a clamp is fixedly connected to the side end of the sliding column. By setting up the mechanism, the lithium battery device can be fixed by the flexible clamp, thereby preventing it from falling off during movement and testing.

[0013] The beneficial effects of this utility model are: through the cooperation of the platform and the positioning mechanism, three-coordinate and multi-angle scanning of the lithium battery device is realized to ensure comprehensive detection of surface defects. Defects at certain angles will not be missed due to the limitation of the detection direction. At the same time, the location of the defect can be accurately located, thereby improving the reliability of the detection results.

[0014] By adjusting the extension length of the sliding column based on its irregular contact surface, the contact area is increased and the fixing force is enhanced, so that the lithium battery device can be stably and effectively fixed by the flexible clamping mechanism, reducing the detection error caused by equipment shaking or positional displacement, and ensuring the stability of the detection data.

Two side frames 3 are fixedly connected to the upper part of the base 1. A first motor 4 is fixedly connected inside the side frame 3, and a bidirectional lead screw 5 is fixedly connected to the output end of the first motor 4. The first motor 4 drives the bidirectional lead screw 5 to rotate. The end of the bidirectional lead screw 5 is rotatably connected to the side frame 3, and the bidirectional lead screw 5 is adapted to the side frame 3. A detection mechanism 6 is provided at the side end of the side frame 3. A second motor 7 is fixedly connected inside the base 1. A positioning mechanism 8 is provided at the side end of the side frame 3, and a flexible clamping mechanism 9 is provided at the side end of the positioning mechanism 8. The lithium battery device to be tested is placed on the platform 2, and three-coordinate measuring machine detection is achieved through the cooperation of the platform 2 and the positioning mechanism 8. This avoids the inability to detect defects at certain angles, thus ensuring the comprehensiveness and reliability of the detection.

[0028] Reference Figure 1 - Figure 4The positioning mechanism 8 includes a second slide 801 slidably connected inside the side frame 3. The side frame 3 is adapted to the second slide 801. The inner wall of the second slide 801 is threadedly connected to the bidirectional lead screw 5. The inner wall of the second slide 801 is adapted to the bidirectional lead screw 5. A turntable 802 is fixedly connected to the side end of the second slide 801, so that the rotation of the bidirectional lead screw 5 can drive the second slide 801 to move along the inner wall of the side frame 3, thereby driving the turntable 802 to rise and fall.

[0029] Reference Figure 1 - Figure 4 The output end of the second motor 7 is fixedly connected to a rotating rod 803. A rotating groove 804 is provided on the surface of the rotating rod 803. The rotating rod 803 is slidably connected to a drive bevel gear 805 through the rotating groove 804. The rotating groove 804 and the drive bevel gear 805 are adapted to each other. When the second motor 7 starts, it drives the rotating rod 803 to rotate, so that the rotating rod 803 drives the drive bevel gear 805 to rotate through the rotating groove 804.

[0030] Reference Figure 1 - Figure 4 The bottom end of the driving bevel gear 805 is rotatably connected to the turntable 802, and the driving bevel gear 805 is adapted to the turntable 802. The inner wall of the turntable 802 is rotatably connected to the driven bevel gear 806, and the turntable 802 is adapted to the driven bevel gear 806. The surface of the driving bevel gear 805 meshes with the driven bevel gear 806, and the driving bevel gear 805 and the driven bevel gear 806 are adapted to each other. The side end of the turntable 802 is rotatably connected to the clamping platform 807, and the side end of the driven bevel gear 806 is fixedly connected to the clamping platform 807. When the driving bevel gear 805 rotates, the driven bevel gear 806 meshing with the driving bevel gear 805 will follow suit, driving the clamping platform 807 to rotate, thereby driving the lithium battery device on the clamping platform 807 to rotate.

A detection frame 602 is fixedly connected to the side end of the first slide 601. An infrared scanning lamp 603 is provided at the bottom end of the detection frame 602. When the bidirectional lead screw 5 rotates, it drives the lithium battery device to move, and at the same time drives the first slide 601 to move along the inner wall of the side frame 3. This allows the detection frame 602 to bring the infrared scanning lamp 603 close to the lithium battery device for detection during detection, and to move away when the detection is finished.

[0032] Reference Figure 1 - Figure 4The flexible clamping mechanism 9 includes an air pump 901 fixedly connected to the side end of the base 1. The output end of the air pump 901 is connected to the clamping platform 807. Gas is injected into the clamping platform 807 through the air pump 901. An air chamber 902 and a sliding groove 903 are formed inside the clamping platform 807. A piston 904 is slidably connected to the clamping platform 807 through the sliding groove 903. The inner circumference of the clamping platform 807 at this point is equal to the outer circumference of the piston 904. A sliding column 905 is fixedly connected to the side end of the piston 904. A clamp 906 is fixedly connected to the side end of the sliding column 905. When the air pump 901 injects gas into the clamping platform 807, the gas pushes the piston 904 along the sliding groove 903, causing the sliding column 905 to slide. The lithium battery device is then fixed by the clamp 906, allowing the lithium battery device to be fixed by the flexible clamping mechanism 9 and preventing it from falling off during movement and testing.

[0033] Working principle:

[0034] This three-coordinate measuring machine (CCM) support for lithium battery equipment places the lithium battery to be tested on the platform 2. The first motor 4 is started, driving the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 causes the second slide 801 to move along the inner wall of the side frame 3, thereby raising and lowering the turntable 802. When the second motor 7 starts, it drives the rotating rod 803 to rotate, causing the rotating rod 803 to drive the active bevel gear 805 to rotate through the rotating groove 804. When the active bevel gear 805 rotates, the driven bevel gear 806, meshing with the active bevel gear 805, follows suit, driving the clamping platform 807 to rotate, thereby causing the lithium battery on the clamping platform 807 to rotate. This allows the lithium battery to be tested using the coordinated rotation of the platform 2 and the positioning mechanism 8, achieving CCM measurement and preventing defects at certain angles from going undetected, thus ensuring the comprehensiveness and reliability of the testing.

[0035] When the air pump 901 injects gas into the clamping platform 807, the gas pushes the piston 904 along the slide groove 903 to drive the slide column 905 to slide, thereby fixing the lithium battery device through the clamp 906. This allows the flexible clamping mechanism 9 to adjust the extension length of the slide column 905 according to its irregular contact surface, increasing the contact area and improving the fixing force, thus preventing the lithium battery device from falling off during movement and testing.
