As shown in the figure, the conveying device 2 includes a conveying mechanism 21 and a transfer mechanism 22. The conveying mechanism 21 and the transfer mechanism 22 are both arranged on the mounting seat 1, and the transfer mechanism 22 is located on one side of the discharge end of the conveying mechanism 21.

[0040] Further, the conveying mechanism 21 includes a conveying frame 211, a conveying wheel 212, a conveying belt 213 and a conveying driving member 214. The conveying frame 211 is arranged on the mounting seat 1. The conveying wheel 212 is rotatably arranged on the conveying frame 211. The conveying belt 213 is wound around the conveying wheel 212. The conveying driving member 214 is arranged on the conveying frame 211, and the output end of the conveying driving member 214 is connected to the conveying wheel 212. Specifically, the conveying driving member 214 is a motor.

[0041] Furthermore, the transfer mechanism 22 includes a bracket 221, a rodless cylinder 222 and a transfer cylinder 223.

The rodless cylinder 222 is arranged on the bracket 221. The transfer cylinder 223 is arranged on the slider of the rodless cylinder 222.

[0042] During specific application, the conveying drive member 214 transmits driving force to drive the conveying wheel 212 to rotate, and the conveying wheel 212 drives the conveyor belt 213 to rotate, and the tray 6 carrying the battery 7 is placed on the conveyor belt 213, and the conveyor belt 213 conveys the tray 6 and the battery 7 to the working position of the detection fixture 3, and then, the rodless cylinder 222 generates driving force to drive the transfer cylinder 223 to move in the direction of the transfer mechanism 22, and the transfer cylinder 223 moves to the top of the tray 6, and the execution end of the transfer cylinder 223 extends out, and the execution end of the transfer cylinder 223 abuts on both sides of the two opposite positioning columns 62 of the tray 6, and then, the rodless cylinder 222 generates driving force to drive the transfer cylinder 223 to move away from the transfer mechanism 22, and the transfer cylinder 223 moves the tray 6 to the predetermined position of the detection fixture 3, and then, the detection fixture 3 drives the tray 6 and the battery 7 to move to the detection position of the detection device 4 for detection.

[0043] Preferably, the conveying mechanism 21 further includes a lifting assembly 215. The lifting assembly 215 is located at the junction of the conveying mechanism 21 and the transfer mechanism 22. Figure 6 , Figure 6 1 is a schematic diagram of the structure of the jacking assembly 215 in the first embodiment of the present invention. As shown in the figure, the jacking assembly 215 includes a jacking drive 2151 and a jacking block 2152. The jacking drive 2151 is arranged on the conveying frame 211, and specifically, the jacking drive 2151 is a cylinder. The jacking block 2152 is arranged at the output end of the jacking drive 2151, and the jacking block 2152 has a groove on one side away from the output end of the jacking drive 2151, and a universal ball 2153 is arranged in the groove. During specific application, the conveyor belt 213 conveys the tray 6 carrying the battery 7 to the work station of the lifting assembly 215, and the lifting drive 2151 drives the lifting block 2152 to rise. The lifting block 2152 lifts the tray 6 carrying the battery 7, reducing the friction between the tray 6 and the conveyor belt 213, thereby increasing the service life of the tray 6 and the conveyor belt 213. At the same time, the universal ball 2153 can also reduce the friction between the lifting block 2152 and the tray 6 when the transfer cylinder 223 moves the tray 6.

[0044] Refer to Figure 7 , Figure 7 Schematic diagram of the structure of the detection fixture 3 in the first embodiment of the present invention. As shown in the figure, the detection fixture 3 includes a fixture moving driver 31 and a clamping fixture 32. The fixture moving driver 31 is arranged on the mounting seat 1. Specifically, the fixture moving driver 31 is a single-axis manipulator. The clamping fixture 32 is arranged on the fixture moving driver 31. The fixture moving driver 31 drives the clamping fixture 32 to move back and forth between the discharge end of the conveying mechanism 21 and the detection device 4.

[0045] Refer to Figure 8 and Fig. 9 , Figure 8Schematic diagram of the structure of the clamping fixture 32 in the first embodiment of the present invention; Fig. 9 1 is another structural schematic diagram of the detection fixture 3 in the first embodiment of the present invention. As shown in the figure, the clamping fixture 32 includes a mounting frame 321, a lifting component 322 and a fixing component 323. The lifting component 322 is arranged on the mounting frame 321. The fixing component 323 is arranged on the mounting frame 321, and the fixing component 323 is opposite to the lifting component 322.

[0046] In specific application, first, the fixture moving drive 31 drives the clamping fixture 32 to move to the discharge end of the corresponding conveying mechanism 21, and secondly, the transfer mechanism 22 moves the tray 6 carrying the battery 7 to the predetermined position of the mounting frame 321; thirdly, the lifting assembly 322 lifts the tray 6 carrying the battery 7, and the tray 6 drives the battery 7 to move toward the fixing assembly 323, and moves to the upper surface of the battery 7 and abuts against the fixing assembly 323, thereby clamping and fixing the battery 7; finally, the fixture moving drive 31 drives the clamping fixture 32 to move to the detection station of the detection device 4, and the detection device 4 detects the battery 7 clamped and fixed by the clamping fixture 32.

[0047] Preferably, a roller 3211 is provided on the mounting frame 321. When the tray 6 carrying the battery 7 is moved to a predetermined position of the mounting frame 321, since the roller 3211 is continuously rotating, when the tray 6 slides on the roller 3211, the sliding friction is converted into rolling friction, thereby reducing the friction between the tray 6 and the mounting frame 321, thereby increasing the service life of the tray 6 and effectively reducing the subsequent repair and maintenance costs.

[0048] Refer to Fig.10 , Fig.10 Schematic diagram of the structure of the jacking assembly 322 in the first embodiment of the present invention. As shown in the figure, the jacking assembly 322 includes a jacking drive 3221 and a jacking plate 3222. The jacking drive 3221 is arranged on the mounting frame 321, and the jacking drive 3221 is located below the supporting plate 61. The output end of the jacking drive 3221 faces the supporting plate 61. Specifically, the jacking drive 3221 is a cylinder. The jacking plate 3222 is arranged at the output end of the jacking drive 3221, and the jacking plate 3222 is movably connected to the supporting plate 61.

[0049] In specific application, the fixing assembly 323 includes a fixing frame 3231 and a fixing plate 3232. The fixing frame 3231 is arranged on the mounting frame 321, and the fixing plate 3232 is "L" shaped. The fixing plate 3232 is arranged on the fixing frame 3231, and the fixing plate 3232 is provided with an avoidance opening adapted to the shape of the positioning column 62 to prevent the fixing plate 3232 from interfering with the positioning column 62 during the clamping and fixing process, and failing to compress the battery 7 well.

[0050] In specific application, the lifting driving member 3221 generates a driving member to drive the lifting plate 3222 to move toward the fixing plate 3232, and the lifting plate 3222 drives the tray 6 carrying the battery 7 to move toward the fixing plate 3232, and the upper surface of the battery 7 abuts against the lower surface of the fixing plate 3232 to achieve vertical fixation of the battery 7.

[0051] Preferably, the lifting plate 3222 has a lifting protrusion 32221 on one side close to the supporting plate 61, and the supporting plate 61 has a lifting groove 611 on one side close to the lifting plate 3222. The lifting protrusion 32221 matches the shape of the lifting groove 611. When the lifting assembly 322 lifts the tray 6 to move toward the fixing assembly 323, the lifting protrusion 32221 is inserted into the lifting groove 611, so that the tray 6 can be prevented from being offset during the lifting process. In this embodiment, the number of the lifting protrusions 32221 is four, and correspondingly, the number of the lifting grooves 611 is also four. The four lifting protrusions 32221 and the four lifting grooves 611 cooperate with each other to limit the position of the tray 6; of course, the number of the lifting protrusions 32221 and the lifting grooves 611 can be adaptively increased or decreased according to actual needs. The above is only one embodiment of the present invention and should not be limited thereto.

[0052] Refer to Fig.11 , Fig.11 Schematic diagram of the structure of the stop assembly 324 in the first embodiment of the present invention. As shown in the figure, the clamping fixture 32 also includes a stop assembly 324. The stop assembly 324 is arranged on the mounting frame 321, and the stop assembly 324 is located on one side of the lifting assembly 322. Specifically, the stop assembly 324 includes a stop driving member 3241 and a stop plate 3242. The stop driving member 3241 is arranged on the mounting frame 321, and the output end of the stop driving member 3241 faces the supporting plate 61. Specifically, the stop driving member 3241 is a cylinder. The stop plate 3242 is arranged at the output end of the stop driving member 3241, and the stop plate 3242 is movably connected to the supporting plate 61.

[0053] In specific applications, the stop plate 3242 has a stop groove 32421, and the supporting plate 61 has a stop column 612 whose shape matches the stop groove 32421. When the tray 6 carrying the battery 7 moves to the predetermined position of the mounting frame 321, the stop drive 3241 generates a driving force to drive the stop plate 3242 to move toward the supporting plate 61, so that the stop column 612 of the supporting plate 61 is inserted into the stop groove 32421 of the stop plate 3242, thereby blocking the supporting plate 61 and preventing the tray 6 from sliding out of the clamp along the direction of the roller 3211 under the action of inertia. In this embodiment, the number of the stopping grooves 32421 is two, and correspondingly, the number of the stopping columns 612 is also two. The two stopping grooves 32421 and the two stopping columns 612 cooperate with each other to stop the tray 6; of course, the number of the stopping grooves 32421 and the stopping columns 612 can be adaptively increased or decreased according to actual needs. The above is only one embodiment of the present invention and should not be limited to this.

[0054] Preferably, the clamping fixture 32 of the present application also includes a rotating drive member 325. The rotating drive member 325 is arranged on the fixture moving drive member 31, and the output end of the rotating drive member 325 is connected to the mounting frame 321. Specifically, the rotating drive member 325 is a reduction motor. In specific applications, after the lifting component 322 cooperates with the fixing component 323 to clamp and fix the battery 7, the rotating drive member 325 can generate a driving force to drive the mounting frame 321 to rotate, thereby driving the battery 7 to rotate, each time rotating 90 degrees. In this way, the four corner detection parts of the battery 7 can be detected by clamping and fixing the battery 7 only once, which effectively improves the detection efficiency.

[0055] Refer to Fig.12 , Fig.12 Schematic diagram of the structure of the detection device 4 in the first embodiment of the present invention. As shown in the figure, the detection device 4 includes an X-ray emitting mechanism 41 and an image acquisition mechanism 42. The X-ray emitting mechanism 41 and the image acquisition mechanism 42 are arranged opposite to each other on the mounting seat 1, and the X-ray emitting mechanism 41 and the image acquisition mechanism 42 are respectively located on both sides of the fixture moving drive member 31.

[0056] Furthermore, the X-ray emitting mechanism 41 includes a first movable platform 411 and an X-ray emitter 412. The first movable platform 411 is disposed on the mounting seat 1, and the first movable platform 411 is located on one side of the fixture moving driving member 31. The X-ray emitter 412 is disposed on the first movable platform 411.

[0057] Furthermore, the image acquisition mechanism 42 includes a second mobile platform 421 and an image acquisition device 422. The second mobile platform 421 is disposed on the mounting seat 1, and the second mobile platform 421 is located on the other side of the fixture moving drive member 31. The image acquisition device 422 is disposed on the second mobile platform 421, and specifically, the image acquisition device 422 is a camera.

[0058] The structures and operating principles of the first mobile platform 411 and the second mobile platform 421 are consistent. The structures and operating principles of the first mobile platform 411 and the second mobile platform 421 are specifically described below by taking the first mobile platform 411 as an example. The first mobile platform 411 includes a lateral moving component and a longitudinal moving component. The lateral moving component has the same structure as the longitudinal moving component, and both the lateral moving component and the longitudinal moving component include a fixed seat, a lead screw, a lead screw nut, a sliding plate and a servo motor. The lead screw is rotatably arranged on the fixed seat. The lead screw nut is sleeved on the lead screw. The sliding plate is slidably arranged on the fixed seat through the guide rail slider, and the sliding plate is connected to the lead screw nut. The output end of the servo motor is connected to one end of the lead screw. In this way, the sliding plate is driven to slide by the servo motor, thereby driving the X-ray generator or the image collector 422 to move in the X direction or the Y direction, so as to achieve the purpose of adjusting the position to adapt to the detection of batteries 7 of different sizes.

[0059] In specific application, the fixture moving drive 31 drives the detection fixture 3 to move, and the detection fixture 3 drives the tray 6 carrying the battery 7 to move to the detection station of the detection device 4, that is, the part of the battery 7 to be detected is located between the X-ray emitter 412 and the image collector 422, and the X-ray emitter 412 emits X-rays to irradiate the part of the battery 7 to be detected, and the image collector 422 takes pictures and collects the images and feeds them back to the control system of the X-RAY detection machine for analysis to determine whether the detected battery 7 is a good product. If it is a good product, continue to detect the next battery 7 or other parts of the battery 7 to be detected. If all are qualified, they are collected and unloaded; if there is an unqualified part during the detection process, the detection of the battery 7 is stopped, and then the defective products are marked with subsequent conveying and unloading collection.

[0060] Preferably, the image acquisition mechanism 42 further includes an image intensifier 423, which is located between the image acquisition device 422 and the X-ray emitter 412, and the image intensifier 423 is close to the image acquisition device 422. In specific applications, the X-ray emitter 412 emits X-rays to irradiate the part to be inspected of the battery 7, and the image is projected on the image intensifier 423, which amplifies the image so that the image acquisition device 422 can take pictures and collect clear images for analysis.

[0061] Embodiment 2

[0062] Please refer to Fig.13 , Fig.13It is a structural schematic diagram of the X-RAY detection machine in the second embodiment of the present invention. As shown in the figure, the X-RAY detection machine of this embodiment includes a mounting seat 1, two conveying devices 2, two detection fixtures 3 and a detection device 4. The two conveying devices 2 are arranged in parallel on the mounting seat 1. Two detection fixtures 3 are arranged on the mounting seat 1, and the two detection fixtures 3 are respectively arranged on one side of the output end of the two conveying devices 2. The detection device 4 is arranged on the mounting seat 1, and the detection device 4 is located between the two conveying devices 2. In this embodiment, the structure of the conveying device 2, the detection fixture 3 and the detection device 4 is consistent with that in the first embodiment, and will not be repeated here.

[0063] For ease of explanation, in this embodiment, the two conveying devices 2 are respectively represented as the first conveying device 201 and the second conveying device 202, and the two detection fixtures 3 are respectively represented as the first detection fixture 301 and the second detection fixture 302. The first detection fixture 301 and the second detection fixture 302 are respectively movable corresponding to the discharge ends of the first conveying device 201 and the second conveying device 202.

[0064] In this embodiment, the first conveying device 201 and the second conveying device 202 are used for dual-channel conveying and feeding. When the first detection fixture 301 is at the detection station of the detection device 4 for detection, the second detection fixture 302 moves to the discharge end of the corresponding conveying device 2 to receive the next battery 7 for clamping and fixing. After the detection device 4 completes the detection of the battery 7 clamped and fixed by the first detection fixture 301, the first detection fixture 301 When the battery 7 is moved to the non-detection station, the first detection fixture 301 drives the battery 7 to rotate 90 degrees. At the same time, the second detection fixture 302 drives another battery 7 to move to the detection station of the detection device 4 for detection. After the detection device 4 completes the detection of the battery 7 driven by the second detection fixture 302, the second detection fixture 302 drives the battery 7 to move to the non-detection station. The first detection fixture 301 drives the rotated battery 7 to move to the detection station of the detection device 4 again for detection. The second detection fixture 302 moved to the non-detection station also drives the battery 7 to rotate 90 degrees. This is repeated. The first detection fixture 301 and the second detection fixture 302 respectively drive the battery 7 to move to the detection device 4 alternately to detect the four corners of the battery 7. Since the operations of conveying, fixing and rotating the battery 7 are all performed at the non-detection station, the time for the battery 7 to arrive at the detection station is further shortened compared with the first embodiment, so that the detection efficiency is further improved. Moreover, after one battery 7 is moved away from the detection station, the other battery 7 arrives at the detection station immediately, thereby improving the use efficiency of the detection device 4.

[0065] Embodiment 3

[0066] Please refer to Fig.14 , Fig.14It is a structural schematic diagram of the X-RAY detection machine in the third embodiment of the present invention. As shown in the figure, the X-RAY detection machine of this embodiment includes a mounting seat 1, four conveying devices 2, four detection fixtures 3 and two detection devices 4. The four conveying devices 2 are arranged in a group of two on the mounting seat 1. The four detection fixtures 3 are respectively arranged on one side of the output end of the four conveying devices 2. Two detection devices 4 are arranged on the mounting seat 1, and the two detection devices 4 are respectively located between each group of two conveying devices 2. In other words, the X-RAY detection machine of this embodiment is composed of two X-RAY detection machines in the second embodiment, which are arranged one after the other.

[0067] For ease of explanation, the two X-RAY detection machines in this embodiment are respectively represented as a first detection machine and a second detection machine, and correspondingly, the detection device 4 is respectively represented as a first detection device 401 and a second detection device 402.

[0068] The difference between the X-RAY inspection machine of this embodiment and that of the second embodiment in inspecting the battery 7 is that: the inspection station of the first inspection device 401 only inspects two corners of the battery 7 on the diagonal line of the four corners, and then the inspection station of the second inspection device 402 inspects the other two corners of the battery 7 on the diagonal line of the four corners. In this way, the inspection fixture 3 only needs to drive the battery 7 to rotate 180 degrees, which further shortens the time for the battery 7 to be in place compared with the first embodiment, thereby improving the inspection efficiency.

[0069] In order to facilitate the transfer of the battery 7 from the first inspection machine to the second inspection machine, the X-RAY inspection machine of this embodiment also includes a conveying device 5. The structure and operating principle of the conveying device 5 are similar to the structure and operating principle of the conveying mechanism 21. The only difference between the two is that the conveying device 5 has two lifting components 215, and the two lifting components 215 are located at the feeding end and the discharging end of the conveying frame 211. The detection fixture 3 moves to the feeding end of the corresponding conveying device 5 after the detection of the first inspection device 401 is completed. When the transfer mechanism 22 moves the tray 6 carrying the battery 7 to the conveying device 5, one of the two lifting components 215 supports the tray 6; when the tray 6 carrying the battery 7 is transferred to the discharging end of the conveying device 5, one of the two lifting components 215 supports the tray 6, and the other transfer mechanism 22 moves the tray 6 carrying the battery 7 to the second inspection machine.

[0070] In specific applications, the above-mentioned conveying device 2, the detection fixture 3 and the detection device 4 are all electrically connected to the control system of the X-RAY detection machine, and the control system of the X-RAY detection machine controls the conveying device 2, the detection fixture 3 and the detection device 4 to achieve the effect of automatic control of the X-RAY detection machine. Of course, the control system of the X-RAY detection machine can be any one of an industrial computer, a PLC or a single-chip microcomputer, which will not be repeated here.

[0071] To sum up, in one or more embodiments of the present invention, the X-RAY inspection machine of the present invention adopts dual-channel feeding, and the operations of conveying, fixing and rotating the battery are all performed at non-inspection stations, thereby shortening the time it takes for the battery to be in place and improving the inspection efficiency. In addition, the batteries are inspected alternately, thereby improving the utilization efficiency of the inspection device.

[0072] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
