Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of battery production, and particularly relates to a built-in mesh plate detection device for a storage battery. BACKGROUND

[0002] In the production and manufacturing process of the storage battery, each single cell of the pole group needs to be treated with acid. Because the internal volume of the single cell is small and contains residual gas, direct filling is not only time-consuming, but also difficult to operate. Therefore, a vacuum automatic acid adding machine is generally used in industrial production to form negative pressure by extracting the air inside the battery, thereby accelerating the speed of acid injection.

[0003] Although this method improves the acid adding speed, it can cause the acid flow rate to increase, enhance the impact force of the acid on the diaphragm of the pole group, and thus cause the risk of diaphragm damage. Therefore, some manufacturers set a mesh plate above the pole group and below the acid injection port. When the acid is added, the acid impacts on the mesh plate instead of directly impacting on the diaphragm of the positive and negative poles, and the mesh plate can disperse the impact force of the acid to protect the diaphragm.

[0004] In the current production process, the mesh plate is placed in each single cell of the pole group by artificial way during the open conveying stage when the battery shell is not capped. Artificial placement is prone to cause the mesh plate to be missed due to negligence, resulting in the loss of diaphragm protection for some single cells of the pole group. In the prior art, there is a lack of effective detection of the mesh plate, and only manual visual inspection can be relied on. The detection accuracy is affected by the fatigue degree of the work and is prone to missed detection, which causes the storage battery product to fail due to the invalidation of the diaphragm protection, and affects the yield and service life of the storage battery product.

DETAILED DESCRIPTION

[0023] The utility model is further illustrated below in connection with the drawings and specific embodiments.

[0024] Embodiment 1: in connection with Figs. 1-2 It can be known that a battery built-in net board detection device, including conveyer belt 1, the left and right sides along the length direction of conveyer belt 1 are equipped with net board detection mechanism and shell positioning mechanism respectively, shell positioning mechanism includes fixed clamp plate 2 and movable clamp plate 3 that can move along the width direction of conveyer belt and cooperate with fixed clamp plate 2, net board detection mechanism includes the detection head 4 that sets up above fixed clamp plate 2 and detects the net board above pole group.

Preferably, the driving member 6 is a telescopic rod, and the telescopic direction of the telescopic rod is consistent with the length direction of the conveyer belt 1.

[0026] Optionally, the detection head 4 is an optical sensor, which detects the presence of the screen plate by emitting infrared light or laser and detecting the change in reflected or transmitted light intensity.

[0027] The screen plate used by the applicant in actual use is pink. Optionally, the detection head 4 is an RGB color sensor, which supports ambient light compensation by analyzing the red, green, and blue light spectra and identifying the RGB value of the screen plate (pink corresponds to a high typical R value). For example, TCS34725, AMS TCS34725, AMS AS7341, MAX44005, etc.

[0028] In existing storage batteries, the number of pole groups is generally even. Taking the case where the number of pole groups is 6, the number of detection heads 4 of the utility model is 3. After the shell positioning mechanism positions the storage battery shell, the three detection heads correspond to the first, third, and fifth pole groups of the storage battery, respectively, and detect whether the screen plates above them are present. Subsequently, the driving member 6 extends, and the detection heads move as a whole and detect the second, fourth, and sixth pole groups of the storage battery.

[0029] The shell positioning mechanism includes a positioning cylinder 7, the extension direction of the positioning cylinder 7 is parallel to the width direction of the conveying belt 1, and the movable clamping plate 3 is arranged on the extension end of the positioning cylinder 7. The movable clamping plate 3 and the fixed clamping plate 2 cooperate to clamp and fix the storage battery. One side of the positioning cylinder 7 is provided with a proximity sensor for detecting whether the storage battery is in place.

[0030] The movable clamping plate 3 includes a clamping portion 8 arranged in the conveying direction of the conveying belt and an intercepting portion 9 arranged on the clamping portion 8, the length direction of the intercepting portion 9 is perpendicular to the length direction of the clamping portion 8. The intercepting portion 9 is arranged at one end of the clamping portion 8, and the storage battery is intercepted by the intercepting portion 9 after moving to one side of the clamping portion 8. The length of the intercepting portion 9 is shorter than the width of the storage battery shell, so that the storage battery shell can be stably clamped between the movable clamping plate 3 and the fixed clamping plate 2.

[0031] The width of the conveying belt 1 is greater than the width of the storage battery shell, and two guide plates 10 are horizontally spaced above the conveying belt 1.

Compared with the number of the detection heads 4 being half of the number of the pole groups, the number of the detection heads is increased, and the arrangement of the driving member 6 is reduced.

[0035] The working principle of the battery built-in screen plate detection device provided by the utility model is as follows: (taking a battery with six pole groups as an example) when working, the battery moves with the conveying belt 1, is intercepted by the interception part 9 of the shell positioning mechanism after being guided by the two guide plates 10, then the conveying belt stops, the positioning cylinder 7 extends to make the movable clamping plate 3 cooperate with the fixed clamping plate 2 to clamp and fix the battery, at this time, the three detection heads correspond to the first, third and fifth pole groups of the battery pole groups respectively, and detect whether the screen plates above the pole groups are present or not, then the driving member 6 extends, the detection heads move as a whole, and detect the second, fourth and sixth pole groups of the battery in correspondence, after the detection is completed, the positioning cylinder 7 is reset, the conveying belt 1 continues to run, and when passing through the push-out cylinder 12, the defective products are pushed from the conveying belt 1 to the defective product collecting platform 13, and the good products continue to move.
