[0002] As demand for lithium batteries continues to grow across various industries, the production efficiency and reliability requirements for lithium battery testing equipment are further increasing. Existing lithium battery testing equipment, particularly prismatic lithium battery testing equipment, places the battery flat on a reference platform when testing prismatic lithium batteries. A secondary positioning mechanism applies a thrust to the battery, causing it to move relative to the reference platform and contact the reference edge, completing secondary positioning. The testing mechanism then contacts the battery to measure its external dimensions.

[0074] In some embodiments, the connecting plate 524 is provided with a piece, an upper end surface of which is respectively connected to the left and right ends of the support plate 525 , and a lower end surface of which is respectively connected to the left and right ends of the bottom plate 527 .

[0075] The size detection mechanism realizes active secondary positioning battery transfer through the linear slide rail and cylinder mechanism during the secondary positioning process, solves the friction problem between the battery bottom and the reference platform, and improves the battery appearance yield.

[0076] In some embodiments, such as Figure 8 As shown, the pressure detection module is a battery clamping force control unit, which includes a sensor fixing block 531, a cam follower 532, a force transmission block 533, and a pressure sensor 534; the sensor fixing block 531 is a circular frame structure, one end of the pressure sensor 534 is locked with the inner side of the sensor fixing block 531, and the other end is locked with the force transmission block 533.

[0077] In some embodiments, two sets of linear bearings are mounted on both ends of the force transmission block 533, with a cam follower 532 mounted on top. The two sets of linear bearings ensure that pressure is transmitted to the pressure sensor 534 parallel to the axis of the linear bearings. The cam follower 532 cooperates with the cam assembly 508. When the cam assembly 508 actuates, causing the cam follower 532 to follow, the force transmission block 533 transmits force to the pressure sensor 534, thereby enabling pressure detection.

[0078] In some embodiments, such as Figure 9 As shown, the sorting unloading conveyor belt includes an unloading belt, and channel 1 601, channel 2 602, channel 3 603, channel 4 604, and a discharge barcode scanner 605 arranged above the unloading belt. Each channel is composed of two sets of adjacent roller assemblies. The roller assembly structure is consistent with the roller guide bar 201 and is installed in the same manner as the roller guide bar 201. In addition, the discharge barcode scanner 605 is installed in the same or the same manner as the entry barcode scanner.

[0079] In some embodiments, the channel 1 601 and the channel 4 604 are battery channels with abnormal dimensions, while the channel 2 602 and the channel 3 603 are battery channels with acceptable dimensions.

[0080] In some embodiments, two groups of discharge barcode scanning guns 605 are provided, which are fixed above channel two 602 and channel three 603 respectively, for identifying and uploading battery information.

[0081] like Figure 7 As shown, in the embodiment of the present application, the square battery size detection equipment includes a loading and scanning station 701, a variable distance loading station 702, a loading clamp 703, a size detection station 704, a blanking clamp 705, a sorting and blanking station 706, and a blanking and scanning station 707.

[0082] In the embodiment of the present application, the detection implementation process of the square battery size detection device is as follows:

[0083] The rectangular batteries 708 to be inspected are transferred to the loading and scanning station 701, where a barcode scanner identifies the battery information. Loading and scanning station 701 then conveys the rectangular batteries 708 to the variable-distance loading station 702. Variable-distance loading station 702 adjusts the distance of the rectangular batteries 708. Loading grippers 703 grab the rectangular batteries 708 and place them in the size inspection station 704, which measures the dimensions of the rectangular batteries 708. After inspection, unloading grippers 705 grab the rectangular batteries 708 and place them in the sorting and unloading station 706. Sorting and unloading station 706 adjusts the distance of the rectangular batteries 708 that meet the requirements and conveys them to channels two and three. Unqualified batteries are conveyed directly to channels one and four of the unloading and scanning station 707.

[0084] like Figure 5 、 Figure 6 、 Figure 7 As shown, the initial state of the implementation process of the size detection station 704 is as follows: Figure 5 In the middle, the cam assembly 508 is in the return state, and the right-angle moving seat 504 is in the retreat state; Figure 6 In the middle, the traverse cylinder 514 is pushed out and the detection cylinder 517 is retracted; Figure 7 In the process, the detection cylinder of the width detection module 521 retracts, the push-pull cylinder 522 retracts, and the lifting and positioning cylinder 523 is pushed out.

[0085] The inspection process of the size inspection station 704 is as follows:

[0086] The battery is placed by the robot Figure 7 On the support plate 525, the detection cylinder of the width detection module 521 is pushed out to complete the secondary positioning of the battery width and measure the battery width size at the same time; the lifting and positioning cylinder 523 retracts, and the push-pull cylinder 522 is pushed out to actively transfer the battery. At this time, the large surface of the battery is aligned with the Figure 5 The marble end surface of the inner surface of the right-angle fixing seat 505 is in contact with the battery, completing the active transfer of the battery, reducing the sliding friction distance between the bottom of the battery and the support plate 525, and avoiding scratches on the battery.

[0087] Figure 5 The servo motor of the cam assembly 508 rotates, and the cam assembly 508 reaches the push state. The right-angle movable seat 504 simultaneously pushes out the clamped battery. The pressure detection module 503 senses that the clamping force reaches the set value, and the servo motor stops rotating. At the same time, the thickness detection sensor 507 probe contacts and compresses the marble end face inside the right-angle fixed seat 505, completing the measurement of the battery thickness.

[0088] In addition, in this application, Figure 6 As shown in , the transverse cylinder 514 retracts, the detection cylinder 517 is pushed out, and the detection block 516 contacts the upper cover of the battery. At this time, the detection block 511 drops synchronously, contacts and compresses the detection head of the detection sensor 512 to complete the height detection of the battery.

[0089] In the embodiment of the present application, the square battery size detection device completes the detection of the battery width, thickness, and height through the above mechanical actions. After the detection process is completed, each mechanism returns to the initial state and the robot grabs the battery blank.

[0090] In the embodiment of the present application, the square battery size detection device is used for detection of batteries in a vertical position without a flipping mechanism, thereby simplifying the mechanical structure and reducing the manufacturing cost of the device.

[0091] In the embodiment of the present application, the square battery size detection equipment combines the battery sorting mechanism with the conveyor belt, which saves the transportation mechanism and reduces the equipment manufacturing cost.

[0092] In the embodiment of the present application, the square battery size detection device drives a dual-channel sorting mechanism through a single motor, and the device has low manufacturing cost, high transmission efficiency and low energy consumption.

[0093] In the embodiment of the present application, the square battery size detection device has a small relative displacement between the battery and the reference platform, no scratches on the battery shell, and low production cost.
