[0002] In the manufacturing process of new energy PACK, the board is one of the key components, and its quality is directly related to the performance and stability of the entire system. However, in the existing technology, there are often some problems with the detection and positioning methods of the board. The traditional detection method mainly relies on the inspectors to measure directly with a ruler. Although this method is simple and easy to use, it has many shortcomings. First of all, it is easy to damage the board by measuring directly with a ruler; because the board is full of precision electronic components and welding points, once the ruler accidentally touches these parts, it may cause short circuits, open circuits and other faults, thereby damaging the board, which not only increases the manufacturing cost, but also may affect the performance and safety of the entire new energy PACK. Secondly, the accuracy of the traditional detection method cannot be guaranteed; due to the interference of human factors, such as hand shaking and visual errors during measurement, the measurement results may be inaccurate. The size and position accuracy of the board are crucial to the performance of the new energy PACK. Once the detection is inaccurate, it may cause the performance of the entire system to decline or fail. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0025] The utility model provides a lithium battery module board measurement device, referring to Figure 1-Figure 3 ,include:

[0026] Workbench 1;

[0027] A base plate 2 is mounted on the upper part of the workbench 1; a standard slot 20 for detecting the board 4 to be tested is provided on the base plate 2, and a standard positioning hole 21 for detecting the positioning hole 40 to be measured on the board 4 to be tested is also provided on the bottom wall of the standard slot 20; and

[0028] The lifting and resetting mechanism 3 is arranged at the lower part of the workbench 1; the lifting and resetting mechanism 3 includes a top plate 31 and a driving member 32 installed under the workbench 1 for driving the top plate 31 to move up and down; the workbench 1 and the bottom plate 2 are connected to each other and are provided with a through slot 5 for the top plate 31 to pass through, and the board 4 to be tested is placed in the standard slot 20 for testing. After the testing is completed, the driving member 32 drives the top plate 31 to push the board out of the standard slot 20.

[0029] Specifically, refer to Figure 1 and Figure 2 The workbench 1 serves as the basis of the entire measuring device and provides a stable support for the bottom plate 2 and the lifting and resetting mechanism 3; the bottom plate 2 is installed on the upper part of the workbench 1, and a standard slot 20 for detecting the board 4 to be tested is provided on the bottom plate 2. The standard slot 20 is formed by demoulding the board 4 according to the standard size, and its size is accurate, so that the size of the board 4 to be tested can be accurately measured. A standard positioning hole 21 for detecting the positioning holes 40 to be measured on the board 4 to be tested is also provided on the bottom wall of the standard slot 20. The existence of these positioning holes 40 to be measured can ensure the accuracy and stability of the board 4 to be tested during installation and fixation; the lifting and resetting mechanism 3 is installed on the lower part of the workbench 1, and includes a top plate 31 and a driving member 32 for driving the top plate 31 to move up and down. The design of this structure enables the driving member 32 to drive the top plate 31 to push the board out of the standard slot 20 after the detection is completed, so that the tester can take out the tested board. At the same time, when the tester takes out the board after testing, the driving member 32 will drive the top plate 31 to move downward, return to the initial state, and prepare for the next test. Therefore, the device can improve the accuracy and efficiency of board measurement.

[0030] During the measurement process, first, according to Figure 2As shown, the board 4 to be tested is placed in the standard slot 20 on the base plate 2. This step is to detect whether the size of the board 4 to be tested is consistent with the size of the standard board or within the acceptable fluctuation range. If the board 4 to be tested can be engaged in the standard slot 20, then the size test of the board 4 to be tested is qualified; Next, the tester uses a rubber rod to detect the positioning hole 40 to be tested of the board 4 to be tested and the standard positioning hole 21 on the base plate 2. If the rubber rod does not encounter any obstacles during the detection process, then the positioning hole 40 to be tested of the board 4 to be tested is qualified; The design of the device structure not only improves the accuracy and efficiency of board measurement, but also is easy to operate and maintain. Through precise measurement and positioning, the quality and performance of the board for lithium battery modules can be ensured, thereby improving the stability and reliability of the entire lithium battery module. At the same time, the device also has a wide range of application prospects and can be applied to the measurement of boards of different sizes and specifications.

[0031] Among them, refer to Figure 3 The driving member 32 can be set as a cylinder. As a common driving member 32, the working principle of the cylinder is to generate power through air pressure or hydraulic pressure to drive the piston to move linearly. The cylinder has the advantages of simple structure, rapid action, and easy control. Therefore, the cylinder drives the top plate 31 to do linear reciprocating motion, which can not only achieve precise displacement control, but also ensure the stability and reliability of the top plate 31 in high-speed motion. In addition to the cylinder, there are other driving structures that can drive the top plate 31 to do linear reciprocating motion, such as electric push rods, linear motors, etc.

[0032] Specifically, the top plate 31 is configured as an I-shaped plate, and the through groove 5 is configured as an I-shaped groove compatible with the top plate 31. The I-shaped plate configured can stably support the board. The through groove 5 is a groove reserved on the workbench 1 and the bottom plate 2 that is compatible with the I-shaped plate. Its function is to ensure that the I-shaped plate can pass through the bottom plate 2.

[0033] It should be noted here that a gravity sensing device 6 is provided on the top plate 31, wherein the gravity sensing device 6 can be set as a piezoelectric sensor. This device is provided to prevent safety accidents caused by misoperation or negligence; specifically, if a board card is placed on the top plate 31 but is not removed and directly reset, or if the next board card test is carried out without resetting the previous board card test, the gravity sensing detection device will detect that an object is placed. In this case, even if the reset button is pressed, the top plate 31 will not move. The setting of this fool-proof mechanism effectively avoids safety problems such as equipment damage or personal injury caused by misoperation or negligence.

[0034] Specifically, the bottom plate 2 is detachably mounted on the workbench 1, and different bottom plates 2 and standard slots 20 on the bottom plate 2 can be adjusted according to the detection of boards of different models, sizes, and appearances. By detachably and fixedly connecting the bottom plate 2 to the workbench 1, the operator can easily replace and adjust the bottom plate 2 according to the characteristics of the board to be detected, which not only simplifies the operation process, but also greatly improves the detection efficiency.

[0035] In addition, the workbench 1, the bottom plate 2, and the top plate 31 are all made of insulating materials, mainly to prevent the passage of electric current, thereby ensuring the safe operation of the equipment. If the workbench 1, the bottom plate 2, or the top plate 31 are not made of insulating materials, then when the equipment is powered on, the current may flow through these components, causing equipment damage, performance degradation, and even fire and other serious safety problems, and when the operator performs various operations on the workbench 1, if the workbench 1 is not made of insulating materials, then they may face the risk of electric shock. Therefore, the selection of insulating materials can greatly reduce this risk and ensure the safety of the operator.

[0036] An elastic buffer layer is provided on the surface of the top plate 31 near the side of the board to be tested 4, and the elastic buffer layer can be made of a material with excellent elasticity and buffering performance, such as silicone, rubber, etc. When the protective board is pushed by an external force, the elastic buffer layer can be deformed to absorb and disperse the impact force, thereby reducing damage to the board.

[0037] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
