Technical Field

[0001] The utility model relates to the technical field of battery module welding, in particular to an intelligent identification mechanism for module welding points. Background Art

[0002] In lithium-ion battery systems, the battery module is of paramount importance. Due to the combined tolerances of the individual cell and the packaging process, the heights of the individual terminals within the module vary, with many variations exceeding 1mm. When milling the module top, it's easy to over-mill (or under-mill), requiring module rework or even scrapping, resulting in a high volume of waste. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides an intelligent identification mechanism for module solder joints, which solves the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a module welding point intelligent identification mechanism, including a mounting part, one side of the mounting part is fixedly connected to a mounting cover, the other side of the mounting part is fixedly connected to a slide cylinder assembly, the telescopic end of the slide cylinder assembly is fixedly connected to a movable plate, one side of the movable plate is fixedly connected to a side block, one side of the side block is slidably connected to a measuring head mechanism, the outer side of the top of the measuring head mechanism is sleeved with a spring, the top of the measuring head mechanism extends to the top of the side block, the bottom end of the measuring head mechanism passes through the bottom of the side block and is installed with an adjustment block, and the bottom of the adjustment block is installed with a measuring round head.

[0005] Preferably, the top end of the spring is fixedly connected to the bottom of the top of the side block, and the bottom end of the spring is fixedly connected to the top of the measuring head mechanism.

[0006] Preferably, a plurality of guide bars are provided on one side of the slide cylinder assembly, and a guide groove matching the guide bars is provided on one side of the movable plate.

[0008] Preferably, a reflective sheet is fixedly connected to one end of the measuring head mechanism and located inside the mounting cover, and a laser rangefinder is fixedly connected to one side of the mounting member and located inside the mounting cover.

[0009] The utility model provides a module solder joint intelligent identification mechanism, which has the following beneficial effects:

It is installed on the milling equipment to achieve accuracy when milling the module and accurately locate the module height, thereby solving the problem that the actual module is caused by the tolerance of the battery cell and the tolerance of the PACK processing process. The height of each pole in the module is different, and there will be both incomplete milling and over-milling. In this way, the two situations of incomplete milling and over-milling are avoided to the greatest extent, and scrap is reduced. By adding a milling machine height measuring mechanism, each batch of batteries only needs to measure the base height once, and the subsequent points are automatically measured and compensated by the equipment, reducing the error of manual measurement, and also greatly reducing the workload of the operator and the risk of manual error.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] See also Figures 1 to 2The utility model provides a technical solution: a module welding point intelligent identification mechanism, including a mounting part 11, one side of the mounting part 11 is fixedly connected to a mounting cover 6, and the other side of the mounting part 11 is fixedly connected to a slide cylinder assembly 1, the telescopic end of the slide cylinder assembly 1 is fixedly connected to a movable plate 8, one side of the movable plate 8 is fixedly connected to a side block 9, and one side of the side block 9 is slidably connected to a measuring head mechanism 2, and a spring 7 is sleeved on the outer side of the top of the measuring head mechanism 2, the top of the measuring head mechanism 2 extends to the top of the side block 9, the bottom end of the measuring head mechanism 2 passes through the bottom of the side block 9 and is installed with an adjusting block 3, and a measuring round head 4 is installed at the bottom of the adjusting block 3. In order to realize the adjustable length function of the measuring round head 4, one end of the measuring round head 4 can be extended into the interior of the adjusting block 3 and connected with the internal thread of the adjusting block 3. By adjusting and rotating the measuring round head 4, one end of the measuring round head 4 can be screwed out from the inside of the adjusting block 3 to adjust the length of the measuring round head 4. The length adjustable function of the measuring round head 4 can also be achieved by other connection methods and other structures.

[0016] The top end of the spring 7 is fixedly connected to the bottom of the top of the side block 9, and the bottom end of the spring 7 is fixedly connected to the top of the measuring head mechanism 2, and the measuring head mechanism 2 is pressed forward by the elastic force of the spring 7.

[0017] A plurality of guide bars 12 are provided on one side of the slide cylinder assembly 1 , and a guide groove 13 cooperating with the guide bars 12 is provided on one side of the movable plate 8 . The guide bars 12 cooperate with the guide groove 13 to limit the movement of the movable plate 8 .

[0018] One side of the slide cylinder assembly 1 is fixedly connected to a mounting base plate 5 , and through the mounting base plate 5 , the mechanism can be mounted on a milling device for operation.

[0019] A reflective sheet 10 is fixedly connected to one end of the measuring head mechanism 2 and located inside the mounting cover 6, and a laser rangefinder is fixedly connected to one side of the mounting part 11 and located inside the mounting cover 6. When the measuring head mechanism 2 is pushed forward toward the module, the laser rangefinder cooperates with the reflective sheet 10 to perform real-time measurement of the extended distance of the measuring round head 4.

[0020] In summary, when the module welding point intelligent identification mechanism is used, the piston end of the slide cylinder assembly 1 pushes the movable plate 8 and the side block 9 downward, so that the measuring head mechanism 2 drives the adjusting block 3 and the measuring round head 4 to move downward and pushes it to the position to be measured by the module until the measuring round head 4 presses the module and the elastic force of the spring 7 presses the measuring head mechanism 2 forward. The slide cylinder assembly 1 pushes the measuring head mechanism 2 to press the module. When the force is greater than the force of the spring 7, the measuring round head 4 retracts to prevent the measuring round head 4 from being crushed by a hard collision. When the measuring head mechanism 2 is pushed forward toward the module, the extending distance of the measuring round head 4 is measured in real time through the reflective sheet 10, and then compared with the reference The position zero difference is calculated to obtain the actual height zero of the module at this point to the extended position of the measuring head 4, and then the control system automatically calculates the actual height of this point and compensates this point relative to the reference position, so that the milling equipment will not mill too large or too small when processing this position, ensuring the processing accuracy and reducing scrap. By installing the base plate 5, the mechanism can be easily installed on the milling equipment. By configuring the measuring head 4, the module point height can be accurately measured to reduce errors. At the same time, it is also equipped with an adjustment block 3, which can adjust the length of the measuring head 4 to complete the compatibility of various height module measurements.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
