[0055] The embodiments of the present application disclose a pre-welding insulation withstand voltage test equipment.

[0056] Please refer to Figure 1 An embodiment of the pre-welding insulation withstand voltage test equipment provided in the embodiments of the present application comprises:

[0057] The rack 100, the jacking device 200, the locking device 400 and the detection device 300.

[0058] The jacking device 200 is mounted on the rack 100 and connected with a workpiece carrier (not shown in the figure) for jacking the workpiece carrier; the workpiece carrier is used for carrying a workpiece to be tested (a battery module).

[0059] The jacking device 200 is provided with a first positioning structure 500; correspondingly, the workpiece carrier is provided with a second positioning structure which is positioned and connected with the first positioning structure 500.

[0060] The detection device 300 is mounted on the rack 100 and located above the jacking device 200, and is used for detecting the workpiece to be tested on the workpiece carrier.

[0061] The locking device 400 is mounted on the rack 100 and is used for clamping the workpiece carrier in the horizontal direction to lock the horizontal position of the workpiece carrier.

[0062] The pre-welding insulation withstand voltage test equipment designed in the present application has the following beneficial effects:

[0063] 1. Through the designed jacking device 200, the workpiece carrier can be driven in the vertical direction at one time, the butt joint with the logistics line can be quickly and efficiently realized, the logistics speed is greatly improved, and the efficiency of battery module detection is improved.

[0064] 2. Through the first positioning structure 500, the vertical direction positioning of the workpiece carrier can be accurately realized by cooperating with the corresponding second positioning structure on the workpiece carrier. At the same time, through the use of the locking device 400, the position of the workpiece carrier in the horizontal direction can be effectively locked, the stability of the workpiece carrier is ensured, and the accuracy of the battery module detection is improved.

[0065] The above is an embodiment of the pre-welding insulation withstand voltage test equipment provided by the embodiment of the application. The following is an embodiment of the pre-welding insulation withstand voltage test equipment provided by the embodiment of the application. For details, please refer to Figures 1 to 6 .

[0066] Based on the scheme of the above embodiment one:

[0067] Further, as shown in Figure 2 and Figure 3 , for the design of the jacking device 200, two jacking mechanisms 1 are included; the two jacking mechanisms 1 are respectively arranged on both sides of the logistics line area reserved by the rack 100; the jacking mechanism 1 includes a jacking piece 12 and a jacking driver 11; the jacking driver 11 is connected with the jacking piece 12 and is used to drive the jacking piece 12 to jacking movement; the first positioning structure 500 is arranged on the jacking piece 12.

[0068] The design of the jacking mechanism 1 makes the equipment more stable during jacking, avoids the problem of tilting or shaking of the workpiece carrier caused by a single jacking point, and further improves the stability and accuracy of the battery module detection. At the same time, the two jacking mechanisms 1 are respectively arranged on both sides of the logistics line area reserved by the rack 100, which is also convenient for interfacing with the logistics line, improving the compatibility and flexibility of the equipment.

[0069] Further, as shown in Figure 2 and Figure 3 , the jacking mechanism 1 further includes a transmission assembly 13; the jacking driver 11 is horizontally arranged; the jacking piece 12 is vertically and slidingly arranged (specifically, the sliding arrangement is achieved through a sliding rail, and the sliding rail is installed on the rack 100); the transmission assembly 13 is connected with the driving end of the jacking mechanism 1 and the jacking piece 12, and is used to convert the horizontal driving displacement of the driving end of the jacking driver 11 into the vertical displacement of the jacking piece 12. This design not only simplifies the structure of the jacking device 200, but also effectively utilizes the space, making the entire equipment more compact. Through the conversion of the transmission assembly 13, the jacking driver 11 can be horizontally arranged, thereby reducing the demand for vertical space, which is particularly important for some space-limited places. At the same time, the vertically sliding jacking piece 12 can ensure the stability of the workpiece carrier during jacking, avoiding detection errors caused by shaking.

[0070] Further, as shown in Figure 3As shown, for the design of the transmission assembly 13, it includes a first transmission member 131 and a second transmission member 132; the first transmission member 131 is horizontally slidingly arranged (specifically slidingly arranged through a sliding rail, which is mounted on the rack 100), and a guide slope 1311 is arranged thereon; the driving end of the jacking driver 11 is connected with the first transmission member 131, for driving the horizontal movement of the first transmission member 131; the second transmission member 132 is fixed to the jacking member 12, and can contact and relatively displace with the guide slope 1311.

[0071] When the jacking driver 11 drives the horizontal movement of the first transmission member 131, the guide slope 1311 on the first transmission member 131 will contact and push the second transmission member 132 to vertically displace, thereby driving the jacking member 12 to vertically ascend or descend. This design not only realizes the conversion from horizontal driving to vertical displacement, but also ensures the stability and accuracy of the transmission process through the design of the guide slope 1311.

[0072] The jacking driver 11 can be a telescopic air cylinder, which is installed in parallel with the first transmission member 131 on one side of the first transmission member 131, and is connected with the first transmission member 131 through a connecting structure (such as a connecting rod or a connecting block). This design can reduce the length of the installation direction, and the structure is more compact.

[0073] Further, the first transmission member 131 can be a wedge block structure, and the second transmission member 132 can be a roller member. The design of the second transmission member 132 as a roller member reduces the friction between the second transmission member 132 and the guide slope 1311, so that the transmission is smoother, and the durability and service life of the equipment are improved.

[0074] Further, since the battery module is heavy, if the workpiece carrier is directly jacked by the jacking trolley, the detection device 300 may have inconsistent contact distances at local positions, i.e., height differences, which may affect the detection results. Therefore, as shown, Figure 2 The jacking mechanism 1 of the present application includes at least two jacking members 12 and at least two transmission assemblies 13; the at least two jacking members 12 are sequentially and spacedly distributed; the transmission assemblies 13 are connected with the jacking members 12 one by one; the adjacent transmission assemblies 13 are connected through a connecting member 14, which can be a rod structure; and the jacking driver 11 is connected with one of the transmission assemblies 13.

[0075] This design not only enhances the carrying capacity of the jacking device 200, but also makes the jacking process more stable and uniform, avoids the stress concentration problem caused by single-point jacking, and makes the equipment more balanced in structure, thereby improving the overall stability and reliability. In addition, by connecting the adjacent transmission assemblies 13 through the connecting member 14, one power source can be used for driving, which realizes the synchronization and coordination of the transmission process, and reduces the manufacturing cost.

[0076] Furthermore, the distribution design of the at least four jacking members 12 corresponds to the at least four first positioning structures 500. For example, the four first positioning structures 500 constitute a stable plane to ensure smooth support of the workpiece carrier, so that the detection plane of the workpiece carrier is not inclined, thereby avoiding defects in the detection effect.

[0077] Further, as shown in Figures 1 to 3 The locking device 400 includes at least two locking mechanisms 2. The locking mechanisms 2 are arranged at both ends of the jacking device 200 and include locking members 22 and locking drives 21. The locking drives 21 are connected with the locking members 22 and are used to drive the locking members 22 to move away from or close to the jacking device 200.

[0078] The design of the locking mechanism 2 can effectively clamp the workpiece carrier in the horizontal direction and ensure the stability of the workpiece carrier during detection. By arranging the locking mechanisms 2 at both ends of the jacking device 200, synchronous locking of both ends of the workpiece carrier can be achieved, improving the accuracy and reliability of locking.

[0079] The locking mechanism 2 can be four, arranged at both ends of the two jacking mechanisms 1. The locking drive 21 can specifically drive the locking member 22 to swing close to or away from the workpiece carrier to achieve a clamping form of locking, or to drive the locking member 22 to translate close to or away from the workpiece carrier to achieve a translational form of clamping locking.

[0080] Further, as shown in Figure 2 and Figure 3 The first positioning structure 500 includes a jacking column 41 and / or a positioning column 42. Preferably, both the jacking column 41 and the positioning column 42 are designed. The positioning column 42 is arranged on one side of the jacking column 41.

[0081] The jacking column 41 can achieve accurate positioning of the workpiece carrier in the vertical direction, and the positioning column 42 can further enhance the stability of the workpiece carrier in the horizontal direction. The two cooperate to ensure accurate positioning and stability of the workpiece carrier during detection. At the same time, the use of the locking device 400 clamps the workpiece carrier with the locking member 22, further locking the position of the workpiece carrier, preventing displacement of the workpiece carrier during detection, thereby ensuring the accuracy and reliability of detection.

[0082] For example, the first positioning structure 500 includes the positioning column 42 and the jacking column 41. The second positioning structure can include a positioning slot for the positioning column 42 to insert and a jacking slot for the jacking column 41 to insert.

[0083] Further, as shown in Figures 4 to 6As shown, the detection device 300 includes a plurality of detection assemblies 31; the plurality of detection assemblies 31 are staggered on the rack 100; the detection assembly 31 includes a detection driver 311 and a detection probe 312; the detection driver 311 is connected with the detection probe 312, and is used to drive the detection probe 312 to move up and down. The detection driver 311 can be a telescopic air cylinder or other linear displacement module, and the specific type is not limited.

[0084] Through the staggered distribution of the plurality of detection assemblies 31, simultaneous detection of different positions of the battery module can be realized, greatly improving the detection efficiency. The detection driver 311 in each detection assembly 31 is connected with the detection probe 312, and through the driving of the detection driver 311, the up-and-down movement of the detection probe 312 can be accurately controlled, so as to realize the detection requirement of different heights of the battery module. This design not only improves the flexibility of detection, but also ensures the comprehensiveness and accuracy of detection. At the same time, the simultaneous work of the plurality of detection assemblies 31 also further shortens the detection period and improves the production efficiency.

[0085] Further, as shown in Figure 4 The rack 100 is installed with a displacement device 32; at least part of the detection assemblies 31 are connected with the displacement device 32 and are driven by the displacement device 32 to move in the horizontal direction.

[0086] The design of the displacement device 32 enables the detection assembly 31 to not only detect the battery module in the vertical direction, but also move in the horizontal direction, so as to realize comprehensive detection of different positions of the battery module. This design greatly enhances the detection capacity and flexibility of the equipment, so that the equipment can adapt to the detection requirements of battery modules of different specifications and sizes. At the same time, the cooperation of the displacement device 32 and the detection assembly 31 also realizes automatic detection, reduces manual intervention, and improves the accuracy and efficiency of detection. In specific implementation, the displacement device 32 can be a slide rail, a lead screw or other structure, and is driven by a motor or an air cylinder. The connection mode of the detection assembly 31 and the displacement device 32 can be direct connection or indirect connection through a connecting frame or other structure. This design not only ensures the stability of the detection assembly 31 during movement, but also improves the overall structural strength and service life of the equipment.

[0087] The above describes in detail the welding insulation withstand voltage test equipment provided by the present application. For those skilled in the art, according to the idea of the embodiments of the present application, the specific implementation and application range will be changed. In view of the above, the content of the specification should not be understood as a limitation of the present application.
