[0032] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0033] First embodiment

[0034] Please refer to Figures 1 to 3 The embodiment of the utility model provides a battery production line (not shown) for producing batteries 200. It can realize automatic detection of batteries 200, with high mechanization, time and labor saving, high detection efficiency and high detection accuracy.

[0035] It should be noted that the battery production line includes a battery production device (not shown) and a battery testing device 100. The battery production device is connected to the battery testing device 100, and the battery production device is used to produce and process the battery 200 and send the battery 200 to the battery testing device 100. The battery testing device 100 is used to perform quality inspection on the battery 200 to ensure the quality of the battery 200.

[0036] The battery detection device 100 includes a conveyor line 110, a clamping fixture 120, a ray generator 130, a ray receiver 140, a controller (not shown), a loading robot 160 and a unloading robot 170. The clamping fixture 120 is connected to the conveyor line 110, and the clamping fixture 120 clamps and fixes the battery 200. The conveyor line 110 is used to drive the battery 200 to move through the clamping fixture 120 to realize the feeding function of the battery 200. Specifically, the ray generator 130 and the ray receiver 140 are relatively arranged on both sides of the battery 200, and are both electrically connected to the controller. The ray generator 130 is used to emit detection rays toward the battery 200, and the ray receiver 140 is used to receive the detection rays passing through the battery 200, and send the obtained energy attenuation data to the controller. The controller is used to analyze the energy attenuation data to determine whether the battery 200 is abnormal. In this way, the battery 200 can be automatically inspected, with a high degree of mechanization, saving time and effort, high inspection efficiency and high inspection accuracy.

[0037] Further, during the detection of the battery 200, first, the conveyor line 110 drives the battery 200 to a preset detection position through the clamping fixture 120; then the ray generator 130 and the ray receiver 140 are started. The ray generator 130 emits detection rays (X-rays) towards the battery 200. After passing through the battery 200, the detection rays form different degrees of energy attenuation and are captured by the ray receiver 140 to form energy attenuation data; then the ray receiver 140 sends the energy attenuation data to the controller, and the controller converts it into an image and analyzes it to determine whether the battery 200 is abnormal; if it is abnormal, it means that the battery 200 is a defective product with quality defects; if there is no abnormality, it means that the battery 200 is a good product without quality defects.

[0038] In this embodiment, the number of batteries 200 is multiple, and the number of clamping fixtures 120 is multiple. The multiple clamping fixtures 120 are arranged on the conveyor line 110 at intervals in sequence. The conveyor line 110 can drive the multiple clamping fixtures 120 to move in a cycle, and each clamping fixture 120 is used to clamp and fix one battery 200. Specifically, after one battery 200 is detected, the conveyor line 110 drives the next battery 200 to the preset detection position through the clamping fixture 120, so as to facilitate the detection of the next battery 200. In this way, the cycle greatly improves the quality detection efficiency of the battery 200, saving time and effort.

[0039] It should be noted that the loading manipulator 160 and the unloading manipulator 170 are oppositely arranged at both ends of the conveyor line 110. The loading manipulator 160 is used to transport the produced battery 200 to the clamping fixture 120, so that the conveyor line 110 can drive the battery 200 to move through the clamping fixture 120. The unloading manipulator 170 is used to sort the detected battery 200 from the clamping fixture 120 to the defective product conveyor roller path or the good product conveyor roller path for subsequent processes of defective product batteries and good product batteries respectively.

[0040] It should be noted that the detection of the battery 200 generally includes the detection of foreign objects inside the battery 200 and the detection of the state of the battery tab. Among them, the detection of foreign objects inside the battery 200 is to use detection rays to detect the large surface 210 of the battery 200 (the battery 200 is in a rectangular shape, and the large surface 210 is the surface with the largest area among the six surfaces of the battery 200), and the detection of the state of the battery tab is to use detection rays to detect the state of the battery tab of the battery 200.

[0041] In this embodiment, the number of the ray generators 130 and the ray receivers 140 is both two, and the position of each ray generator 130 corresponds to the position of a ray receiver 140. Among them, one ray generator 130 is used to emit detection rays to the large surface 210 of the battery 200, and the corresponding ray receiver 140 is used to receive the detection rays passing through the large surface 210 of the battery, and the controller is used to detect whether there is a foreign object inside the battery 200; the other ray generator 130 is used to emit detection rays to the tab of the battery 200, and the corresponding ray receiver 140 is used to receive the detection rays passing through the tab of the battery, and the controller is used to detect the attitude of the tab of the battery 200.

[0042] Preferably, the battery detection device 100 further includes a position sensor 180. The position sensor 180 and the conveyor line 110 are both electrically connected to the controller. The position sensor 180 is used to control the conveyor line 110 to pause through the controller when detecting that the battery 200 moves to a preset detection position, so as to facilitate the ray generator 130 and the ray receiver 140 to detect the quality of the battery 200, and the controller is used to control the conveyor line 110 to restart after the quality detection is completed. Specifically, since the battery 200 is clamped in the clamping fixture 120, it can effectively avoid the situation that the battery 200 moves back and forth due to inertia in the clamping fixture 120 when the conveyor line 110 pauses or restarts, preventing friction between the battery 200 and the clamping fixture 120, thereby avoiding scratching the battery 200 or generating dust.

[0043] In this embodiment, the clamping direction of the clamping fixture 120 is the same as the conveying direction of the conveyor line 110, so as to facilitate the loading manipulator 160 to send the battery 200 to the clamping fixture 120, and facilitate the unloading manipulator 170 to take out the battery 200 in the clamping fixture 120.

[0044] The clamping fixture 120 includes a first mounting bracket 121, a second mounting bracket 122, a driving member 123, a movable end 124 and a fixed end 125. The first mounting bracket 121 and the second mounting bracket 122 are arranged at intervals and are both connected to the conveyor line 110, and the conveyor line 110 can drive the first mounting bracket 121 and the second mounting bracket 122 to move synchronously. The driving member 123 is installed on the first mounting bracket 121 and is connected to the movable end 124, and the fixed end 125 is connected to the second mounting bracket 122. The driving member 123 is used to drive the movable end 124 to approach the fixed end 125 to clamp the battery 200 between the movable end 124 and the fixed end 125, so as to realize the clamping and fixing of the battery 200.

[0045] It should be noted that one side of the movable end 124 adjacent to the large surface 210 of the battery abuts, and the fixed end 125 abuts against the other side adjacent to the large surface 210 of the battery. That is, neither the movable end 124 nor the fixed end 125 will block the large surface 210 of the battery 200, so as to ensure the accuracy of the detection of the large surface 210 of the battery and facilitate the controller to accurately judge whether there is foreign matter inside the battery 200.

[0046] In this embodiment, the conveyor line 110 includes two parallel and spaced conveyor belts 111 that move synchronously. The first mounting frame 121 is connected to both conveyor belts 111 at the same time. One end of the first mounting frame 121 is connected to one conveyor belt 111, and the other end is connected to the other conveyor belt 111. The second mounting frame 122 is connected to both conveyor belts 111 at the same time. One end of the second mounting frame 122 is connected to one conveyor belt 111, and the other end is connected to the other conveyor belt 111. The two conveyor belts 111 move synchronously to drive the first mounting frame 121 and the second mounting frame 122 to move synchronously, and then drive the battery 200 to move.

[0047] Preferably, the clamping fixture 120 further includes a third mounting frame 126 and a backing plate 127. The third mounting frame 126 is disposed between the first mounting frame 121 and the second mounting frame 122 and is connected to the conveyor line 110. The conveyor line 110 can drive the first mounting frame 121, the third mounting frame 126, and the second mounting frame 122 to move synchronously. Specifically, the backing plate 127 is connected to the third mounting frame 126, and the backing plate 127 is used to support the battery 200 to prevent the battery 200 from falling off the clamping fixture 120 and ensure the stability of the battery 200 detection.

[0048] In this embodiment, the third mounting frame 126 is connected between the first mounting frame 121 and the second mounting frame 122 to ensure the synchronous movement of the first mounting frame 121, the third mounting frame 126, and the second mounting frame 122, thereby ensuring the reliability of the conveyor line 110 to drive the battery 200 to move through the clamping fixture 120.

[0049] In this embodiment, the battery 200 is disposed flat on the backing plate 127, that is, the backing plate 127 is used to fit with the large surface 210 of the battery 200 to support the entire battery 200 through the large surface 210 of the battery 200. At this time, the ray generator 130 and the ray receiver 140 for detecting foreign matter inside the battery 200 are oppositely disposed above and below the battery 200, and the ray generator 130 and the ray receiver 140 for detecting the state of the battery tab are oppositely disposed on the left and right sides of the battery 200 (perpendicular to the conveying direction of the conveyor line 110). Specifically, the backing plate 127 is made of a transparent material to avoid blocking the large surface 210 of the battery 200, thereby ensuring the accuracy of the detection of the large surface 210 of the battery.

[0050] The battery detection device 100 provided by the embodiment of the present utility model, the clamping fixture 120 is connected to the conveyor line 110, the clamping fixture 120 clamps and fixes the battery 200, the conveyor line 110 is used to drive the battery 200 to move through the clamping fixture 120, the ray generator 130 and the ray receiver 140 are oppositely arranged on both sides of the battery 200 and are both electrically connected to the controller. The ray generator 130 is used to emit detection rays towards the battery 200, the ray receiver 140 is used to receive the detection rays passing through the battery 200, and send the obtained energy attenuation data to the controller. The controller is used to analyze the energy attenuation data to judge whether the battery 200 is abnormal. Compared with the prior art, the battery detection device 100 provided by the present utility model can realize unobstructed automatic detection of the battery 200 because of the clamping fixture 120 connected to the conveyor line 110 and the ray generator 130 and the ray receiver 140 oppositely arranged on both sides of the battery 200. It has a high degree of mechanization, saves time and effort, has high detection efficiency and high detection accuracy.

[0052] Please refer to Figure 4 and Figure 5 The embodiment of the present utility model provides a battery detection device 100. Compared with the first embodiment, the difference in this embodiment is the posture of the battery 200 during transportation.

[0053] In this embodiment, the battery 200 is arranged vertically on the backing plate 127, that is, the backing plate 127 is used to fit with the adjacent side surface of the large surface 210 of the battery to support the entire battery 200 through this side surface. At this time, the large surface 210 of the battery 200 is perpendicular to the conveyor line 110. The ray generator 130 and the ray receiver 140 for detecting foreign objects inside the battery 200 are oppositely arranged on the left and right sides of the battery 200 (perpendicular to the conveying direction of the conveyor line 110), while the ray generator 130 and the ray receiver 140 for detecting the state of the battery tab are oppositely arranged above and below the battery 200.
