Description

Technical Field

[0001] This invention belongs to the field of battery manufacturing equipment technology, and in particular relates to a battery surface insulation coating detection and repair device. Background Technology

[0002] To ensure the safety and insulation of individual primary cells, an insulating coating is sprayed onto the battery surface. However, the sprayed insulating coating may have insulation defects such as thin coating, scratches, or surface damage. It is necessary to measure the surface insulation resistance of the battery after spraying to determine the possible locations of insulation defects. Then, the surface insulation defect area is inspected to identify the insulation defects and their specific locations are marked and recorded. The surface insulation defect area is then repaired. Finally, the overall surface insulation resistance is measured to confirm that the insulation performance of the repaired battery surface insulating coating is qualified. If the insulation performance of the repaired battery surface insulating coating is still not qualified, the surface insulation resistance measurement, surface insulation defect area inspection, and surface insulation defect area repair are repeated until the insulation performance of the battery surface insulating coating is qualified.

[0003] For prismatic batteries (hereinafter referred to as batteries), please see Figure 1 The battery 10 comprises six casing surfaces (also called battery surfaces): top surface 11, bottom surface, left large surface 12, right large surface, front side surface, and rear side surface 13. On the top surface 11 of a conventional battery 10, from front to back, are distributed the positive terminal 14, electrolyte inlet 15, explosion-proof window 16, QR code 17, and negative terminal 18. The bottom surface, left large surface 12, right large surface, front side surface, and rear side surface 13 are also included. An insulating coating is required on the 5mm edge of the top surface 11, but not on the positive terminal 14, electrolyte inlet 15, explosion-proof window 16, QR code 17, or negative terminal 18. The positive terminal is connected to all six casing surfaces of the battery, while the negative terminal is not.

[0004] Here, facing forward with the front side facing forward, top surface 11 facing upward, and injection port 15 facing forward is called upright; facing forward with the left large surface 12 or right large surface facing forward and top surface 11 facing upward is called horizontal; facing forward with the rear side 13 facing forward, top surface 11 facing upward, and injection port 15 facing backward is called reversed; facing forward with the left large surface 12 or right large surface facing upward is called lying flat; facing forward with the front side or rear side 13 facing upward is called side-standing; and facing upward with the bottom surface is called inverted.

[0005] When measuring the surface insulation resistance of battery 10 and when measuring the overall surface insulation resistance of the battery, the battery is often clamped with the left large surface 12 or the right large surface facing upwards.

[0006] When inspecting the surface insulation defect area of ​​battery 10, the battery surfaces with insulation defects determined by surface insulation resistance measurement, including the left large surface 12, right large surface, front side, rear side 13, and bottom surface, should be clamped with the corresponding orientation facing upwards.

[0007] 1) Surface insulation resistance measurement of battery 10 involves using a resistance meter to measure the insulation coating of the five shell surfaces of the battery (bottom, left large surface 12, right large surface, front side, and rear side 13) and individually measure the resistance value of the positive terminal 14 on the top surface 11 of the battery to determine whether it meets the insulation requirements.

[0008] Requirements for measuring the surface insulation resistance of batteries:

[0009] ① To avoid damaging the insulating coating on the battery surface, conductive adhesive plates are generally attached to the electrode plates to form a combined electrode plate as a probe, and the corresponding insulating coating on the battery surface is pressed onto each conductive adhesive plate surface.

[0010] ② Other components that can contact the combined electrode plate and the positive probe must be insulated. Except for contact with the resistance measuring instrument and battery 10, the combined electrode plate and the positive probe must not be connected to each other or to other components of the device.

[0011] ③ Because the deformation of the battery surface, such as bulging and denting, can cause measurement inaccuracies, appropriate pressure must be applied to the battery surface to eliminate the deformation and solve the measurement inaccuracies. For this purpose, pressure of (100~500)±20kgf is generally applied to the left large surface 12 and right large surface of the battery, pressure of (10~30)±1kgf is applied to the front side and rear side 13, and pressure of (2~5)±1kgf is applied to the top surface 11 and bottom surface. The magnitude of the applied pressure is positively correlated with the size of the area of ​​the pressure surface.

[0012] 2) To detect surface insulation defects in battery 10, a resistance meter is used to measure the resistance of the insulation coating on each of the five shell surfaces (bottom, left large surface 12, right large surface, front side, and rear side 13) against the positive terminal 14 on the top surface 11 of the battery. If electrical breakdown occurs in the insulation defect area, the insulation coating in the insulation defect area will be burned black, forming an insulation defect area mark, and the insulation defect area and its specific location will be recorded.

[0013] Requirements for detecting insulation defects on battery surface:

[0014] ① To avoid damaging the insulating coating on the battery surface, conductive adhesive is usually wrapped around the electrode roller to form a combined electrode roller as a probe, with the conductive adhesive side pressing against the insulating coating on the battery surface.

[0015] ② Other parts that can come into contact with the combined electrode roller and the positive probe must be insulated. Except for contact with the resistance measuring instrument and battery 10, the combined electrode roller and the positive probe must not be connected to each other or to other parts of the device.

[0016] ③ Because the deformation of the battery surface, such as bulging and denting, can cause inaccurate measurements, appropriate pressure must be applied to the battery surface to eliminate the deformation and solve the problem of inaccurate measurements. Therefore, the combined electrode roller must press the battery surface with a certain pressure roller.

[0017] 3) Performing a comprehensive surface insulation resistance measurement on battery 10 involves using a resistance meter to measure the insulation coating on the five casing surfaces of the battery (bottom, left large surface 12, right large surface, front side, and rear side 13) in parallel, and then measuring the resistance value of the positive terminal 14 on the top surface 11 of battery 10 to determine whether it meets the insulation requirements.

[0018] Requirements for overall measurement of battery surface insulation resistance:

[0019] ① To avoid damaging the insulating coating on the surface of battery 10, conductive adhesive plates are generally attached to the electrode plates to form a combined electrode plate as a probe, and the corresponding insulating coating on the surface of the battery is pressed onto each conductive adhesive plate.

[0020] ② Other components that can contact the combined electrode plate and the positive probe must be insulated. In addition to being able to contact the resistance measuring instrument and the battery 10, and being able to communicate with each other, the combined electrode plate and the positive probe must not be able to communicate with each other or with other components of the device.

[0021] ③ Because the deformation of the battery surface, such as bulging and denting, can cause measurement inaccuracies, appropriate pressure must be applied to the battery surface to eliminate the deformation and solve the measurement inaccuracies. For this purpose, pressure of (100~500)±20kgf is generally applied to the left large surface 12 and right large surface of the battery, pressure of (10~30)±1kgf is applied to the front side and rear side 13, and pressure of (2~5)±1kgf is applied to the top surface 11 and bottom surface. The magnitude of the applied pressure is positively correlated with the size of the area of ​​the pressure surface.

[0022] Therefore, it is necessary to develop a battery surface insulation coating detection and repair device to detect, identify, and repair insulation defects. Summary of the Invention

[0023] The purpose of this invention is to provide a device for detecting and repairing the insulating coating on the surface of a battery, which can detect, identify and repair insulation defects.

[0028] The first positioning device is located between the side insulation resistance measurement station, the incoming qualified product discharge station, the battery surface insulation defect area detection station, and the CCD detection loading station. It is used to receive the battery after the insulation resistance measurement and to move the battery with the left side facing down in a flat position. The battery can be rotated and flipped so that the battery surface where the insulation defect is located is placed horizontally upward.

[0029] A qualified incoming material discharge conveyor belt is located at the qualified incoming material discharge station, next to the first displacement device, and is used to receive qualified batteries from the batteries after the insulation resistance surface measurement and output them to the outside of this equipment.

[0030] A battery surface insulation defect area detection device is installed at the battery surface insulation defect area detection station, located next to the first displacement device. It is used to receive batteries with horizontally upward-facing insulation defects on the battery surface where the insulation resistance measurement is unqualified, which are moved from the first displacement device. It automatically scans and detects insulation defects in the battery surface insulation coating and marks and records the specific location of the insulation defect area.

[0031] A battery carrier cyclic transfer device is provided at the CCD detection loading station, the CCD detection station, the insulation defect repair station, and the insulation defect repair unloading station. It is used to receive batteries after the insulation defect area is detected at the CCD detection loading station, and keep the surface of the battery where the insulation defect is located horizontally upward, and transfer them sequentially to the CCD detection station, the insulation defect repair station, and the insulation defect repair unloading station.

[0032] The first conveying device is located above the incoming qualified product discharge station, the battery surface insulation defect area detection station, and the CCD detection loading station, next to the first positioning device.

[0033] The CCD detection device is located at the CCD detection station, above the battery carrier cyclic transfer device, and is used to photograph and locate the actual area markings of insulation defects in the battery after the battery surface insulation defect area detection device has detected them.

[0034] An insulation defect repair device is located at the insulation defect repair station, next to the CCD detection device and above the battery carrier cyclic transfer device. It is used to spray insulating material onto the actual area of ​​insulation defect in the battery after the CCD detection device has taken pictures and located it to repair the insulation defect area.

[0035] The second displacement device is located between the overall insulation resistance measurement station and the repair qualified product unloading station. It is used to flip the battery after insulation defect repair and move the battery out in a flat position with the left or right large side facing up.

[0036] An overall insulation resistance measuring device is installed at the overall insulation resistance measuring station, located next to the second displacement device. It is used to measure the insulation resistance value of the insulation coating on five battery surfaces: the left large surface, right large surface, front side, rear side, and bottom surface, and to determine the overall insulation qualification of the insulation coating after the insulation defects on the battery surface have been repaired.

[0037] The unloading device is located at the unloading station for the repaired qualified products. It is used to receive the batteries that have passed the overall insulation resistance measurement after the overall insulation resistance is measured and output them to the outside of this equipment.

[0038] The second conveying device is located between the overall insulation resistance measurement station, the repair qualified product unloading station, and the battery loading station, above the second positioning device, the overall insulation resistance measurement device, the unloading device, and the loading device. It is used to convey batteries with insulation defects repaired from the second positioning device to the overall insulation resistance measurement device, to convey batteries with overall insulation resistance qualified after overall insulation resistance measurement from the overall insulation resistance measurement device to the unloading device, and to convey batteries with overall insulation resistance unqualified after overall insulation resistance measurement from the overall insulation resistance measurement device to the loading device.

[0039] The beneficial effects of this invention are as follows:

[0040] The battery surface insulation coating inspection and repair equipment in this solution is used to inspect the conformity of the battery surface insulation coating and repair unqualified batteries. Batteries on the loading device are moved in by a battery surface insulation resistance measuring device, and the insulation resistance value of each surface insulation coating is measured to determine the conformity of the insulation of each battery surface insulation coating. Then, a first conveying device and a first positioning device work together to move qualified batteries out onto the qualified product discharge conveyor belt, or the first positioning device moves unqualified batteries out with their defective surfaces facing upwards, and then the first conveying device transports them to the battery surface insulation defect area detection device. The battery surface insulation defect area detection device automatically scans and detects insulation defects in the battery surface insulation coating, and marks and records the specific location of the insulation defect area. Then, the first conveying device transports the batteries with surface insulation defect areas detected to the battery carrier. The CCD detection loading station of the ring transfer device; the battery carrier cyclic transfer device sequentially transports batteries to the CCD detection device for photographing and locating the actual areas of insulation defects, and then transports the photographed and located batteries to the insulation defect repair device for spraying insulating material to repair the actual areas of insulation defects, and then transports the repaired batteries to the insulation defect repair unloading station; the second displacement device flips the repaired batteries to a flat position with the left or right large side facing up, and the second transport device transports the flat-positioned repaired batteries from the second displacement device to the overall insulation resistance measuring device for overall insulation testing, and from the overall insulation resistance measuring device, transports batteries with qualified overall insulation resistance after overall insulation resistance measurement to the unloading device, and from the overall insulation resistance measuring device, transports batteries with unqualified overall insulation resistance after overall insulation resistance measurement to the loading device. The batteries are sequentially fed into a battery surface insulation resistance measuring device for surface-by-surface insulation resistance measurement. They then enter a battery surface insulation defect area detection device for defect marking, followed by CCD detection for defect location imaging, and finally an insulation defect repair device for defect repair. The repair effect is then assessed by an overall insulation resistance measuring device until a qualified battery is obtained. This invention's battery surface insulation coating detection and repair equipment performs surface-by-surface defect detection and defect area marking / location before defect repair, and conducts a qualification test after defect repair. The detection is comprehensive, the repair is precise, the automation level is high, and the detection and repair efficiency is high. Attached Figure Description
