Description

Technical Field

[0001] This invention belongs to the technical field of battery manufacturing and testing equipment, and particularly relates to a vertical testing machine for coated batteries. Background Technology

[0002] With the mass production and use of prismatic batteries, the requirements for the dimensional accuracy of prismatic single primary cells (hereinafter referred to as batteries) are becoming increasingly stringent. Precise measurement of the length, thickness, height, and terminal height of the battery is required. Traditional measuring equipment measures the battery by touching its surface with a contact gauge or by illuminating its surface with a non-contact light or sound rangefinder. However, for prismatic batteries, such as square aluminum-cased lithium batteries, the surface may bulge or dent due to insufficient rigidity of the outer shell. Both contact gauges and non-contact light or sound rangefinders can lead to inaccurate measurements due to the deformation of the workpiece itself.

[0003] The surface bulging or denting deformation of prismatic batteries can be eliminated by applying appropriate force constraints during battery module assembly, thus allowing the battery's external dimensions to be measured under appropriate force constraints.

[0004] The clamping pressure applied when measuring the dimensions of a square aluminum-cased lithium battery is generally required to be as follows: thickness measurement (300±20) kgf, adjustable from (100 to 800) kgf, with an accuracy requirement of ±10 kgf; length measurement (10±1) kgf; height measurement (2±1) kgf, which can be adjusted according to the battery specifications and testing requirements.

[0005] The distance between the top and bottom surfaces of the battery is the battery shoulder height; the distance between the positive (or negative) terminal on the top surface and the bottom surface is the battery terminal height; the distance between the front and rear sides of the battery is the battery width; and the distance between the left and right large surfaces of the battery is the battery thickness.

[0006] When individual primary cells are assembled into a module, they are placed close together. To provide electrical isolation, an insulating film needs to be coated on the surface of the potentially adjacent individual primary cells. To reject coated primary cells whose insulation resistance value is lower than a predetermined standard value due to punctures, cracks, or damage to the insulating film, the insulation resistance of the coated primary cells needs to be measured.

[0007] The clamping pressure applied during insulation resistance measurement of coated batteries is generally required to be: adjustable at (50~800)±10kgf in the thickness direction; (10±1)kgf in the length direction; and (2±1)kgf in the height direction. It can be adjusted according to the specific specifications and test requirements of the coated battery.

[0008] As fully charged finished batteries, coated batteries still need to have their voltage measured. As charged batteries, they are generally transported vertically.

[0009] Therefore, a vertical testing machine for coated batteries is needed. Summary of the Invention

For those skilled in the art, the specific meaning of the terms in this invention can be understood according to the specific circumstances.

[0053] See Figure 1-15 This invention discloses a vertical testing machine for coated batteries, used to test the performance of coated batteries in an upright position with the top surface facing upwards. It includes a voltage measuring device 100, a width and height measuring device 200, a pressure-applied thickness measuring device 400, an insulation resistance pressure measuring device 500, and a barcode scanning and discharging device 600. The voltage measuring device 100 measures the battery voltage. The width and height measuring device 200, located at the output end of the voltage measuring device 100, measures the battery shoulder height, terminal height, and battery width. The pressure-applied thickness measuring device 400, located at the output end of the width and height measuring device 200, includes a thickness measuring bracket 410, a thickness measuring feed belt 420, a thickness measuring stop mechanism 430, a thickness measuring clamping mechanism 440, and a pressure-applied thickness measuring mechanism 450. The thickness measuring bracket 410 has a thickness measuring station 411. The thickness measuring feed belt 420 is located below the thickness measuring station 411 and is used to convey batteries in an upright position with the top surface facing upwards. The battery is in a certain state; a thickness measuring stop mechanism 430 is located at the front end of the thickness measuring feed belt 420 at the thickness measuring station 411, used to stop the battery at the thickness measuring station 411; a thickness measuring clamping mechanism 440 is located above the thickness measuring station 411, used to clamp the front and rear sides of the battery and lift the battery to a preset position within the thickness measuring station 411; a pressure-applying thickness measuring mechanism 450 is located at the thickness measuring station 411 and above the thickness measuring feed belt 420, used to apply pressure to measure the thickness between the left and right large surfaces of the battery clamped by the thickness measuring clamping mechanism 440; an insulation resistance pressure measuring device 500 is located at the output end of the pressure-applying thickness measuring device 400, used to apply pressure to measure the insulation resistance value of the insulation layer on the left and right large surfaces of the battery; a barcode scanning and discharging device 600 is located at the output end of the insulation resistance pressure measuring device 500, used to scan the barcode to confirm the battery measurement results, and output qualified and unqualified products respectively.

[0054] See Figure 3-4The vertical testing machine for coated batteries also includes a pitch transfer device 300.

[0055] It should be noted that the width and height measurement time in this solution is shorter than the pressure thickness measurement time. To further shorten the detection time and improve detection efficiency, one width and height measurement station can be matched with multiple thickness measurement stations 411 to achieve continuous battery detection and reduce downtime. Specifically, this solution uses one width and height measurement station to match two thickness measurement stations 411. In practical application, this solution uses two width and height measurement stations to simultaneously detect the shoulder height, terminal height, and battery width of two batteries. There are four variable pitch transfer belts 320. The four variable pitch transfer belts 320 are combined in pairs to form two groups. When one group of variable pitch transfer belts 320 connects to the batteries at the two width and height measurement stations, the other group of variable pitch transfer belts 320 sends the batteries with the detected width and height to the two thickness measurement stations 411 respectively, so as to achieve uninterrupted thickness measurement of the batteries after width and height detection.

Understandably, the voltage measuring mechanism 160 reads the battery voltage value by connecting the positive and negative terminals of the battery. If the read voltage value falls within the voltage value range of the corresponding battery specification, the battery voltage value is qualified; otherwise, the battery voltage value is unqualified.

[0092] In this embodiment, the barcode scanning and discharging device 600 includes a barcode scanning variable pitch mechanism 610, a barcode scanning mechanism 620, a variable pitch discharging mechanism 630, a buffer pull belt 640, an NG discharging pull belt 650, and an OK discharging pull belt 660. The input end of the barcode scanning variable pitch mechanism 610 is connected to the output end of the insulation resistance voltage measuring device 500. The input end of the barcode scanning mechanism 620 is connected to the output end of the barcode scanning variable pitch mechanism 610. The input end of the variable pitch discharging mechanism 630 is connected to the output end of the barcode scanning mechanism 620. The buffer pull belt 640, the NG discharging pull belt 650, and the OK discharging pull belt 660 are connected to the output end of the variable pitch discharging mechanism 630.

[0093] It should be noted that after the battery has been tested, it first enters the barcode scanning variable distance mechanism 610 to adjust the relative distance between the two batteries to match the position of the barcode scanning mechanism 620, so as to facilitate barcode scanning.

[0094] See further Figure 17 The variable-pitch discharge mechanism 630 includes a variable-pitch discharge linear module and four variable-pitch discharge belts. Each of the four variable-pitch discharge belts corresponds to one of the four OK discharge belts 660. Two NG discharge belts 650 and two buffer belts 640 are symmetrically arranged on both sides of the OK discharge belts 660. The four variable-pitch discharge belts sequentially receive batteries output from four insulation resistance voltage measuring devices 500. When all four batteries are qualified, they are simultaneously discharged to the four OK discharge belts 660. When some of the four batteries are qualified and some are unqualified, the qualified batteries are first fed into the buffer belts 640 for buffering, while the unqualified batteries are sequentially fed into the NG discharge belts 650. The qualified batteries from the buffer belts 640 are then collected into the variable-pitch discharge belts, ensuring that there are four qualified batteries on each of the four variable-pitch discharge belts. Finally, the four qualified batteries are simultaneously discharged to the OK discharge belts 660. The 640 buffer pull belt setting is beneficial for the accumulation of qualified batteries, so as to facilitate the neat discharge of qualified batteries and facilitate subsequent packaging and handling.

[0095] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
