DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described 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, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In order to address the shortcomings of the existing technology, such as Figure 1 , 2 As shown, the utility model provides a battery internal defect detection device based on image analysis, the main bodies of the flip mechanism 2 and the transmission mechanism 3 are fixedly connected to the base frame 4, and the detection mechanism 1 is fixedly connected to the output end of the flip mechanism 2.

[0038] It should be noted that, in the process of internal defect detection of the battery, the battery is transported by the conveying mechanism 3, during which the detection mechanism 1 is driven to flip by the flipping mechanism 2 to achieve volume scanning of the battery.

[0039] Specifically, Figure 1 , 3 As shown, a detection mechanism 1 for a battery internal defect detection device based on image analysis, an X-ray tube 11 and a flat panel detector 12 are opposite to each other, and the X-ray tube 11 and the flat panel detector 12 are respectively fixedly connected to corresponding driving components 13.

[0040] It should be noted that the utility model is a battery internal defect detection device based on image analysis. Through the detection mechanism 1, during the battery detection process, the X-ray tube 11 emits X-rays to transmit the battery, and the transmitted impact is irradiated onto the flat-panel detector 12 for imaging. During this period, the X-ray tube 11 and the flat-panel detector 12 can be driven separately by the driving components 13 respectively attached thereto to achieve the position adjustment of the X-ray tube 11 and the flat-panel detector 12.

[0041] Among them, taking the driving component 13 connected to the X-ray tube 11 as an example, the driving component 13 is composed of a motor, a screw and a base frame. The slider attached to the screw is fixedly connected to the main body of the X-ray tube 11, and the driving component 13 is also attached with a sliding seat for limiting the sliding of the slider on the screw.

[0042] Specific, and Figure 1 , 4 As shown, a flip mechanism 2 for a battery internal defect detection device based on image analysis, the ring gear 23 is rotatably connected to the base frame 4, and the rotational connection structure between the ring gear 23 and the base frame 4 can be similar to the connection structure between the slider 315 and the base plate 311; the gear 22 is fixedly connected to the rotor on the motor 21; a reducer 24 is arranged between the motor 21 and the gear 22 to increase the torque of the gear 22.

[0043] It should be noted that the utility model is a battery internal defect detection device based on image analysis. Through the setting of the flipping mechanism 2, during the battery detection process, according to the actual scanning requirements, if the battery volume scan is required, it is necessary to start the motor 21, and the motor 21 drives the gear 22 to rotate. During the rotation of the gear 22, the gear 22 drives the ring gear 23 to rotate, and the ring gear 23 drives the detection mechanism 1 to rotate, and combined with the transmission mechanism 3 to transport the battery, the volume scan of the battery is realized.

[0044] Specific, and Figure 1 , 4 As shown, a transmission mechanism 3 for a battery internal defect detection device based on image analysis, a frame 32 is fixedly connected to a base frame 4, and two sets of sprockets 33 are rotatably connected to the frame 32, the two sets of sprockets 33 are meshed with corresponding chains 34, and a plurality of support components 31 are fixedly connected to the outer wall of the chain 34, the main body of the motor 35 is fixedly connected to the frame 32, and the rotor attached to the motor 35 is fixedly connected to one of the sprockets 33.

[0045] It should be noted that the utility model is a battery internal defect detection device based on image analysis. Through the transmission mechanism 3, during the process of conveying the battery, the motor 2 35 drives the sprocket 33 to rotate, and the sprocket 33 drives the chain 34 to move. During the movement of the chain 34, the support assembly 31 is driven to move. During this period, the battery is placed on the support assembly 31 for loading and unloading.

[0046] Furthermore, if Figure 1 , 4As shown, a support assembly 31 in a transmission mechanism 3 for a battery internal defect detection device based on image analysis, a support rod 312 and a connecting rod 314 are integrally formed, or one end of the support rod 312 is fixedly connected to one end of the connecting rod 314, the bottom end structure of the connecting rod 314 matches the structure of the limiting groove 313, and the upper end structure of the connecting rod 314 matches the structure of the slider 315 and can slide relatively, a spring 316 is provided between the slider 315 and the connecting rod 314, and the two ends of the spring 316 are fixedly connected to the connecting rod 314 and the slider 315 respectively;

[0047] The slider 315 is provided with a sliding seat, and the base plate 311 is provided with a limiting sliding groove that matches the sliding seat structure. The slider 315 is slidably connected with the base plate 311 based on the limiting sliding groove and through the sliding seat.

[0048] It should be noted that the utility model is a battery internal defect detection device based on image analysis. Through the support assembly 31, during the battery loading process, the battery is directly placed on the two support rods 312. Prior to this, the distance between the two support rods 312 needs to be adjusted according to the actual size of the battery to be detected.

[0049] In the process of adjusting the distance between the two support rods 312, the connecting rod 314 is lifted vertically upward to make the connecting rod 314 disengage from the corresponding limiting groove 313. In this process, the connecting rod 314 slides relatively based on the slider 315, and presses the spring 316 to increase the elastic potential energy of the spring 316. After the connecting rod 314 disengages from the corresponding limiting groove 313, the slider 315 can slide relatively based on the base plate 311, so as to achieve the position adjustment of the two support rods 312.

[0050] When the distance between the two support rods 312 is appropriate, the sliding of the slider 315 should be stopped, and the vertical upward force on the connecting rod 314 should be stopped at the same time. Then, the spring 316 is pressed to increase the elastic potential energy of the spring 316. When the connecting rod 314 is no longer under force, the spring 316 needs to release the elastic potential energy to drive the connecting rod 314 to abut against the inside of the limit groove 313, so as to achieve the movement limit of the support rod 312.

[0051] As a preferred embodiment, a groove 312-1 is provided at the upper end of the support rod 312 to limit the placement of the battery, and the support rod 312 can be single-sided open based on the groove 312-1 provided thereon, that is, the grooves 312-1 provided thereon of the two support rods 312 are opposite to each other, thereby ensuring the stability of the battery placed on the two support rods 312 to the greatest extent.

[0052] As mentioned above, in the actual implementation process, in order not to affect the battery detection result, the metal parts such as the sprocket 33 and the chain 34 on the flip mechanism 2 can be replaced with plastic or ceramic materials.

[0053] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
