[0033] In this embodiment, as Figure 1 shown, the battery thickness measuring device includes a support mechanism 10, a pressing mechanism 20, and a thickness measuring unit 30.

[0034] The support mechanism 10 includes a pressing and mounting assembly 120, a battery carrying assembly 140, and a load-bearing assembly 160.

[0035] The support mechanism 10 can be a functional structure connected to the pressing mechanism 20 and the thickness measuring unit 30, and capable of providing a supporting force for the pressing mechanism 20 and the thickness measuring unit 30. The pressing and mounting assembly 120 can be a functional assembly connected to the pressing mechanism 20 and capable of providing a supporting force for the pressing mechanism 20. The battery carrying assembly 140 can be a functional assembly disposed on the load-bearing assembly 160 and capable of carrying the battery and limiting the battery. The load-bearing assembly 160 can be a functional assembly connected to the pressing and mounting assembly 120 and the battery carrying assembly 140, and capable of carrying the pressing and mounting assembly 120 and the battery carrying assembly 140. Optionally, the pressing and mounting assembly 120 can be a pressing and mounting frame. The battery carrying assembly 140 can be a battery carrier. The load-bearing assembly 160 can be a load-bearing bottom plate.

[0036] Optionally, as Figure 2As shown, the battery carrier assembly 140 includes a limit block 1410, a material presence sensor 1420, a battery insulation board 1430, a carrier column 1440, and a carrier mounting plate 1450. The limit block 1410 and the material presence sensor 1420 are disposed on the battery insulation board 1430. The limit block 1410 can abut against the side of the battery, and the material presence sensor 1420 can sense the battery located on the battery insulation board 1430. The carrier mounting plate 1450 is connected to the battery insulation board 1430. One end of the carrier column 1440 is connected to the carrier mounting plate 1450, and the other end of the carrier column 1440 is connected to the load-bearing assembly 160.

[0037] Through the cooperative action of the components in the battery carrier assembly 140, it is possible to determine whether there is a battery in the battery carrier assembly 140 and feedback it to the control system, and provide load-bearing support and limiting functions for the battery when the battery is present.

[0038] Optionally, as Figure 3 shown, the pressing and mounting assembly 120 includes a support column 1210, a reinforcing rib 1220, a pressing and mounting plate 1230, and a column mounting plate 1240. The reinforcing rib 1220 is disposed on the pressing and mounting plate 1230. One end of the support column 1210 is connected to the pressing and mounting plate 1230, and the other end of the support column 1210 is connected to the column mounting plate 1240. The column mounting plate 1240 is disposed on the load-bearing assembly 160.

[0039] Through the cooperative action of the components in the pressing and mounting assembly 120, the support rigidity of the pressing mechanism 20 can be improved, enabling it to withstand the reaction force during pressing without deformation, thereby ensuring the support stability of the pressing mechanism 20.

[0040] The pressing mechanism 20 is disposed on the pressing and mounting assembly 120. The pressing mechanism 20 includes a pressing assembly 220 and a pressure feedback assembly 240. The pressure feedback assembly 240 is connected to the pressing assembly 220. The pressing assembly 220 can drive the pressure feedback assembly 240 to press against the battery located in the battery carrier assembly 140.

[0041] The pressing mechanism 20 can be a functional mechanism disposed on the pressing and mounting assembly 120 that can approach and press against the battery located in the battery carrier assembly 140. The pressing assembly 220 can be a functional component connected to the pressure feedback assembly 240 and the pressing and mounting assembly 120 that can drive the pressure feedback assembly 240 to press against the battery located in the battery carrier assembly 140. The pressing feedback assembly can be a functional component connected to the pressing assembly 220 that can approach and abut against the battery located in the battery carrier assembly 140 under the action of the pressing assembly 220.

[0042] Optionally, as Figure 4As shown in the figure, the pressing assembly 220 includes a pressure driving member 2210, a floating joint 2220, a lower thickness measuring pressing plate 2230, a position sensing sheet metal 2240, a guide post 2250, a limit connecting plate 2260, a groove-shaped optoelectronic device 2270 and a groove-shaped optoelectronic device mounting plate 2280. The pressure driving member 2210 is connected to the lower thickness measuring pressing plate 2230 through the floating joint 2220, and the pressure driving member 2210 can drive the floating joint 2220 and the lower thickness measuring pressing plate 2230 to move in the vertical direction. The limit connecting plate 2260 is arranged around the pressure driving member 2210. The position sensing sheet metal 2240 is arranged on both sides of the limit connecting plate 2260. One end of the guide post 2250 is connected to the limit connecting plate 2260, and the other end of the guide post 2250 is connected to the lower thickness measuring pressing plate 2230. The groove-shaped optoelectronic device 2270 is arranged on the groove-shaped optoelectronic device mounting plate 2280, and the groove-shaped optoelectronic device mounting plate 2280 is connected to the guide post 2250. Optionally, the pressure driving member 2210 includes a servo motor 2211 and a servo cylinder 2212.

[0043] It should be noted that the servo motor 2211 and the servo cylinder 2212 provide the pressing force required for thickness measurement to ensure that the thickness measurement pressure meets the requirements during battery thickness measurement; the connection method of the servo cylinder 2212 to the lower thickness measuring pressing plate 2230 through the floating joint 2220 can eliminate certain deviations and ensure smooth extension and retraction of the servo cylinder 2212; the position sensing sheet metal 2240 forms an integral body with the connecting plate, the guide post and the lower thickness measuring pressing plate 2230, and provides position feedback when the servo cylinder 2212 presses down and retracts to prevent the battery from being damaged due to excessive extension.

[0044] Optionally, as Figure 5 shown, the pressure feedback assembly 240 includes a pressure sensor 2410, an insulating mounting plate 2420 and a pressing insulating plate 2430. One end of the pressure sensor 2410 is connected to the insulating mounting plate 2420, and the other end of the pressure sensor 2410 is connected to the lower thickness measuring pressing plate 2230. The pressing insulating plate 2430 is connected to the insulating mounting plate 2420, and the pressing insulating plate 2430 can be pressed against the battery located in the battery carrying assembly 140 under the action of the pressing assembly 220.

[0045] It should be noted that through the combined action of the components in the pressure feedback assembly 240, the pressure magnitude during the pressing process is collected in real time and fed back to the control system. The control system gives a signal as to whether the servo motor 2211 continues to act and press down, making the entire pressing process form a closed loop, improving the control accuracy and preventing the battery from being damaged due to overpressure of the pressing mechanism 20.

[0046] The thickness measuring unit 30 is connected to the pressing assembly 220 and can measure the thickness of the battery in the pressed state.

[0047] The thickness measurement unit 30 can be disposed on one side of the pressing assembly 220, and can measure the thickness of the battery in a compressed state when the pressing feedback assembly presses on the battery located in the battery carrying assembly 140. Optionally, as Figure 6 shown, the thickness measurement unit 30 includes a sensor mounting block 320 and a displacement sensor 340. The displacement sensor 340 is disposed on the sensor mounting block 320, and the sensor mounting block 320 is connected to the lower pressing plate 2230 of the thickness measurement. Optionally, the displacement sensor 340 can be a laser displacement sensor.

[0048] It should be noted that after the entire pressing operation is completed, the control system gives a signal, and the displacement sensor 340 emits light to measure the distance between the battery insulating plate 1430 and the laser, and feeds it back to the control system for calculation to obtain the battery thickness; by using a laser displacement sensor, higher measurement accuracy can be obtained while reducing the ranging time.

[0049] The battery is transported to the load-bearing assembly 160 in the support mechanism 10 through the upper step conveyor mechanism. After the material presence sensor 1420 in the battery carrying assembly 140 senses the presence of material, the control system outputs a signal to the pressing assembly 220 in the pressing mechanism 20. The servo motor 2211 in the pressing assembly 220 drives the servo cylinder 2212 to press towards the battery, and the pressure sensor 2410 in the pressing feedback assembly monitors the pressure value acting on the battery in real time until the pressure value is stabilized at the standard pressure value set by the control system; when the groove-shaped photoelectric sensor 2270 in the pressing assembly 220 senses the extreme position and the pressure feedback by the pressure sensor 2410 does not reach the pressure requirement for thickness measurement, the battery will be marked as an NG battery; when the pressure feedback by the pressure sensor 2410 reaches the pressure requirement for thickness measurement and the groove-shaped photoelectric sensor 2270 is not triggered, the displacement sensor 340 is activated to measure the thickness of the battery and the result is returned to the control system, and the control system determines whether the battery meets the thickness requirement range.

[0050] This application also provides a processing device, which includes the battery thickness measurement device in the above-mentioned embodiment.

[0051] The division of each module in the above battery thickness measurement device is only for illustrative purposes. In other embodiments, the battery thickness measurement device can be divided into different modules as needed to complete all or part of the functions of the above battery thickness measurement device.

[0052] The battery thickness measurement device and processing equipment provided by the above embodiments, when measuring the thickness of the battery cell, the battery carrying component in the support mechanism receives the battery from the outside, and the pressing component of the pressing and mounting component arranged in the support mechanism drives the pressure feedback component connected thereto to move until it presses on the battery located in the battery carrying component in the support mechanism. At the same time, the thickness measurement unit connected to the pressing component measures the thickness of the battery in the pressed state, so as to realize the measurement of the battery thickness, effectively improving the problem of large deviation values in battery measurement caused by manual operation differences in the case of manually holding a vernier caliper to measure the thickness values of the batteries one by one. Thus, while improving the stability of battery thickness measurement, the efficiency of battery thickness measurement is improved, effectively ensuring the production accuracy of the battery, and having important economic value and practical value for popularization.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
