Description

Technical Field

[0001] The present invention relates to the technical field of new energy battery detection, and in particular to an automatic loading and unloading device for new energy battery detection. Background Art

[0002] When new energy batteries are produced or recycled, they need to be tested with high current. The main purpose of the high current test is to check whether the insulation performance of new energy batteries is good. Usually, direct current or alternating current is used for the test. By observing the changes in the current, voltage, temperature and other parameters of the battery during the test, the reliability, safety and other performance parameters of the battery are evaluated. At the same time, the high current test can also find some potential problems so that timely repairs or adjustments can be made. At present, the high current detection of new energy batteries is generally carried out on an assembly line, that is, each battery passes through the high current detection center in turn, and the detection work is carried out by electrically connecting the pole gauge above the detection center with the pole of the battery. In addition, the pole gauge usually has the function of five-axis linkage to adapt to poles in different positions on the battery.

[0003] Existing high-current testing equipment transports batteries to the loading device at the center of the inspection fixture, and most of them use positioning pins to fix the batteries, and then drive the pole inspection fixture to dock with the battery pole. However, the positioning method of positioning pins can only rely on the initial position of the battery to ensure the accuracy of the fixed position of the new energy battery installation. When the battery model, size and pole position change, the loading device may not be able to achieve the self-centering function of the battery. This positioning method with insufficient flexibility may cause poor contact between the pole inspection fixture of the battery testing equipment and the battery pole when docking, ultimately affecting the detection effect.

[0004] Based on this, an automatic loading and unloading device for new energy battery testing is proposed to solve the above problems. Summary of the invention

[0042] Please combine Figure 3 As shown, the motor drive mechanism includes a servo motor 18 fixedly connected to the lower side of the push plate 4, and the output end of the servo motor 18 is fixedly connected to the third gear 20, and the third gear 20 is meshed with the second gear 19. In this embodiment, the driving unit adopts a servo motor, and other embodiments can use a stepper motor to reduce costs.

[0043] Please combine Figure 3 and Figure 7 As shown, the baffle mechanism includes a limit plate 10 fixedly connected to one side of each fixed plate 3, each limit plate 10 is provided with a groove 27, and the limit plate 10 and the tooth plate 8 are located in the same plane. It should be noted that by setting the limit plate 10, foreign matter can be prevented from entering the groove 6, thereby protecting the pulley 9.

[0044] When the No. 1 gear 7 is located at the initial position of the toothed plate 8, the push plate 4 is at the initial height, the No. 1 connecting plate 22 and the No. 2 connecting plate 23 are at an initial angle with the tie hoop 21 as the end point, and the distance between the two clamping plates 13 is at the initial distance state;

[0045] When the No. 1 gear 7 leaves the initial position and moves along the tooth plate 8 to the highest point of the tooth plate 8, the push plate 4 leaves the initial height and rises upward, the support platform 12 rises, the angle between the No. 1 connecting plate 22 and the No. 2 connecting plate 23 becomes smaller, and the distance between the two clamping plates 13 becomes smaller, and the two clamping plates 13 are in a clamping and feeding state for the new energy battery;

[0046] When the No. 1 gear 7 leaves the highest position of the tooth plate 8 and moves downward, the push plate 4 moves downward to the initial height, the push plate 4 is lowered upward, the support platform 12 is lowered, the angle between the No. 1 connecting plate 22 and the No. 2 connecting plate 23 becomes larger, the distance between the two clamping plates 13 becomes larger, and the two clamping plates 13 are in a state of unloading new energy batteries;

[0047] When the No. 1 gear 7 is located on the tooth plate 8 and is at the lowermost track section of the tooth plate 8, the push plate 4 moves downward from the initial height, the angle between the No. 1 connecting plate 22 and the No. 2 connecting plate 23 is 180 degrees, and the distance between the two clamping plates 13 is at the maximum state.

[0048] Working principle: Place the new energy battery to be tested on the support platform 12, start the servo motor 18, the No. 3 gear 20 rotates to drive the No. 2 gear 19 to rotate. Since the No. 1 gear 7 is fixedly connected to the No. 2 gear 19, the No. 1 gear 7 is meshed with the toothed plate 8 and moves along the surface of the toothed plate 8. When the No. 1 gear 7 moves on the ascending track section of the toothed plate 8, the push plate 4 moves upward along the limit groove 29 on the moving plate 11, and at the same time, the roller group 17 moves to one side along the roller groove 15, and the moving plate 11 moves along the upper side of the fixed plate 3. The pulley 9 rolls on the inner wall of the groove 6 opened on the fixed plate 3, and the pulley 9 and the first gear 7 clamp each other to achieve the limiting effect on the connecting rod 5. As above, when the push plate 4 moves upward, it can directly push the support platform 12 to rise. Since the first connecting plate 22 and the second connecting plate 23 are respectively arranged between the two sides of the tie hoop 21 and the clamping plate 13, at this time, according to the principle of relative motion, the clamping plates 13 on both sides respectively achieve the effect of approaching each other along the limiting slide 26 and the slide rod 24, that is, the new energy is controlled from both sides. The battery clamping function is that when the servo motor 18 pushes the No. 1 gear 7 to move to the highest point of the tooth plate 8, the support platform 12 is at the maximum height, the battery's own pole can be docked with the pole of the detection fixture, and the distance between the two clamping plates 13 is the smallest, which is also the final self-centering clamping state of the battery, and the clamping effect is the most stable. At this time, the angle formed by the No. 1 connecting plate 22 and the No. 2 connecting plate 23 is the smallest. When the No. 1 gear 7 passes the highest point of the tooth plate 8 and continues to move downhill along the side of the tooth plate 8, at this time, under the limiting action of the pulley 9 and the No. 1 gear 7, the push plate 4 moves down, the support platform 12 descends, the No. 1 connecting plate 22 and the No. 2 connecting plate 23 open at an angle, and the function of opening the unloading can be realized. When the No. 1 gear 7 moves along the tooth plate 8 to the lower side of the tooth plate 8, the push plate 4 continues to descend, and the support platform 12 descends together, and the lower side can contact the upper side of the moving plate 11. The No. 1 connecting plate 22 and the No. 2 connecting plate 23 open at an angle and are located on the same straight line. The distance between the two clamping plates 13 is the largest, and then the moving plate 11 returns to the initial position on the fixed plate 3 to carry out the next cycle of unloading and unloading.
