Description

Technical Field

[0001] The present application relates to the technical field of new energy lithium battery manufacturing equipment, and particularly relates to a formation and grading probe module. Background Art

[0002] Currently, in the production process of the lithium battery manufacturing industry, with the booming development of the new energy industry, numerous lithium batteries of different specifications and models have emerged. For manufacturers of medium-sized, large-sized, and extra-large-sized square aluminum shell lithium batteries, how to quickly and efficiently change the production line conditions to match the production tests of lithium batteries of different specifications and sizes has very high economic value.

[0003] There are two existing adjustment devices for the formation and grading needle bed probe module. One is a manual adjustment device. After the device is docked with the needle bed probe module and the locking mechanism of the probe module is unlocked, the operator adjusts the needle bed probe module to the specified position according to the scale indication preset on the needle bed through the handle transmission mechanism on the device. This operation method requires manual intervention throughout the process, is time-consuming and laborious, and has extremely low efficiency, unable to meet the requirements of large-scale production. The other is a non-manual adjustment device that does not have the function of automatically positioning the formation and grading needle bed probe module. Compared with the manual adjustment device, this device does not require manual intervention throughout the process and can automatically unlock the needle bed probe module and then automatically adjust it to the specified position. However, its disadvantage is that the device needs to record the position after the last adjustment of the needle bed probe module or the positioning module on the adjustment device always remains unchanged at the position after the last adjustment, and at the same time, the probe module on the needle bed must also remain unchanged at the position after the last adjustment, which is extremely inconvenient for the daily maintenance operation of the equipment and has great limitations.

[0004] Therefore, a formation and grading probe module is proposed. Content of the Utility Model

[0005] The object of the present utility model is to propose a formation and grading probe module, which solves the problems of inconvenient probe module type change and great practical limitations in the existing ones, thereby realizing stepless transformation of the probe module type, being applicable to batteries of different sizes, saving the type change time, and improving the efficiency of rapid type change.

[0006] In order to achieve the above object, the present utility model adopts the following technical solutions: A formation and grading probe module, a probe array fixing member fixed on the equipment, includes:

[0007] A probe slide rail, fixed to the probe array fixing member;

[0008] A probe fixing seat, arranged on the probe slide rail, capable of sliding or locking on the probe slide rail;

[0009] A charge and discharge probe, arranged on the probe fixing seat, and adjusted by sliding the probe fixing seat on the probe slide rail to adapt to lithium batteries of different sizes.

[0010] Through the mutual cooperation of the charge and discharge probe, the probe fixing base and the probe slide rail, the charge and discharge probe can slide freely on the probe slide rail and be adjusted and locked, so as to be applicable to lithium batteries of different sizes, greatly improving the practical performance, and saving time and effort, with simple and fast operation.

[0011] Preferably, a groove is formed on one side of the probe slide rail, and the probe fixing base is located in the groove.

[0012] Preferably, the probe fixing base includes:

[0013] A cup seat fixing member, which is slidably connected in the groove of the probe slide rail and is used to ensure the levelness of the charge and discharge probe;

[0014] A connecting block, which is connected to the cup seat fixing member. The connecting block is provided with a cup seat nut hole to be fixedly connected to the probe slide rail through a bolt;

[0015] A probe through hole, which is formed in the middle of the connecting block and is used to place the charge and discharge probe.

[0016] Preferably, the probe alignment fixing member is of a rectangular frame structure, and the long side of the rectangular frame structure is perpendicular to the probe slide rail.

[0017] The beneficial effects of the present utility model:

[0018] 1. In the present utility model, by providing a probe fixing base on the probe slide rail, the probe can be steplessly changed, which is applicable to batteries of different sizes, saves the changeover time, improves the efficiency of rapid changeover, and reduces the new changeover requirements of the equipment for battery size changes. At the same time, it also greatly reduces the equipment transformation cost and changeover time cost caused by battery size changes, and occupies a small space, is convenient to use, easy to detect, and easy to maintain.

[0019] 2. In the present utility model, by providing a probe seat fixing member on the probe slide rail, by increasing the length of the probe seat fixing member, during the charging and discharging process of the probe pressing, due to the force between the battery and the probe, the relative displacement between the probe and the battery pole column is reduced.

[0023] The following further explains the usage method of the present utility model in combination with the attached drawings and specific implementation modes.

[0024] As Figure 1 and Figure 2 shown, a formation and grading probe module, the probe array fixing part 1 fixed on the device, mainly realizes locking the entire probe array and stabilizing the relative position between the probe and the positive and negative electrode posts; including:

[0025] Probe slide rail 2, fixed to the probe array fixing part 1;

[0026] Mainly realizes stepless regulation of the probe, quickly and conveniently completes the adjustment and movement of the relevant distances of the probe;

[0027] Probe fixing seat 3, arranged on the probe slide rail 2, can slide or lock on the probe slide rail 2;

[0028] Realizes locking the charge and discharge probe 4 before and after movement on the probe slide rail 2, preventing the phenomenon of the probe sliding and shifting after multiple pressings.

[0029] The lengthened grip of the probe fixing seat 3 reduces the relative displacement between the probe and the battery electrode post due to the force generated by the pressing of the probe and the electrode post. After calibrating the relative position between the probes, the position of the probe is locked.

[0030] Charge and discharge probe 4, arranged on the probe fixing seat 3, is adjusted by sliding the probe fixing seat 3 on the probe slide rail 2 to adapt to lithium batteries of different sizes. And the position of the probe can be adjusted arbitrarily according to the thickness of the blade battery.

[0031] One side of the probe slide rail 2 is provided with a groove 21, and the probe fixing seat 3 is located in the groove 21.

[0032] The probe fixing seat 3 includes:

[0033] Cup seat fixing part 5, slidably connected in the groove 21 of the probe slide rail 2, used to ensure the levelness of the charge and discharge probe 4.

[0034] Connecting block 6, connected to the cup seat fixing part 5, the connecting block 6 is provided with a cup seat nut hole 7 to be fixedly connected to the probe slide rail 2 through a bolt 9; being fixed by the bolt 9 enables the charge and discharge probe 4 to be freely adjusted according to the size of the battery.

[0035] The probe through-hole 8 is opened in the middle of the connection block 6 and is used to place the charge and discharge probe 4.

[0036] The probe alignment fixing member 1 is of a rectangular frame structure, and the long side of the rectangular frame structure is perpendicular to the probe slide rail 2.

[0037] Through the mutual cooperation of the probe alignment fixing member 1, the probe slide rail 2, the probe fixing seat 3, and the charge and discharge probe 4, the square shell battery can maintain a reliable state and a simple state for model change during the charge and discharge process of formation and grading.

[0038] Working process: During model change, after the formation and grading library position needle bed is reset to the correct position, the locking state between the probe and the probe slide rail 2 is released. By turning the bolt 9, the probe fixing seat 3 can move on the probe slide rail 2. Adjust the calibration tooling according to the annular dimension requirements, and adjust the relative position between the probes through the calibration work. Then, through the extended grip of the probe fixing seat 3, the relative displacement between the probe and the battery pole column is reduced. Slide the probe fixing seat 3 to drive the probe to slide on the probe slide rail 2. After completing the calibration of the relative position between the probes, lock the position of the probe through the bolt 9, that is, complete the compatibility modification requirements due to the battery size.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
