Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0052] Please also read Figures 1 to 9 , the transmission device 100 provided in the embodiment of the present application is now described. The transmission device 100 includes a base frame 20, a belt mechanism 30 and a telescopic mechanism 40; the belt mechanism 30 is used to transmit the product 90 to be detected, and the belt mechanism 30 is installed on the base frame 20; the telescopic mechanism 40 is used to drive one end of the belt mechanism 30 to telescope along the transmission direction X of the product 90 to be detected, and the power output end of the telescopic mechanism 40 is connected to one end of the belt mechanism 30, and the telescopic mechanism 40 is installed on the base frame 20.

[0053] In the present application, the telescopic mechanism 40 can control one end of the belt mechanism 30 to extend or retract; when the telescopic mechanism 40 is in the retracted state, the product 90 to be inspected and the tray 10 are transported to the belt mechanism 30 away from the end, and the product 90 to be inspected can be inspected by the CT detection mechanism 60; when the product 90 to be inspected needs to be transmitted through the CT detection mechanism 60, the telescopic mechanism 40 controls one end of the belt mechanism 30 to extend, and transmits the product 90 to be inspected to the other side of the CT detection mechanism 60, so that when the product 90 to be inspected is inspected, the transmission device 100 does not need to pass through the CT detection mechanism 60, which is convenient for avoiding the transmission device 100 when inspecting the end of the product 90 to be inspected, which helps to reduce the image overlap between the transmission device 100 and the product 90 to be inspected, improves the accuracy of the detection result, and can reduce the influence of the transmission device 100 on the CT detection mechanism 60 to a certain extent, which is conducive to increasing the scanning angle, improving the image quality, and further improving the accuracy of the scanning result; after the product 90 to be inspected passes through the CT detection mechanism, the telescopic mechanism 40 can be retracted, and the detection of the next product 90 to be inspected can be repeated. The transport mechanism 100 may also be used to receive upstream products to be inspected 90 . After the products to be inspected 90 are scanned and inspected by the CT inspection mechanism 60 , the tray 10 is transported in a direction away from the CT inspection mechanism 60 .

[0054] The product to be detected 90 in the embodiment of the present application may be, but not limited to, a battery cell, such as a laminated battery cell, etc. The transmission device 100 may be, but not limited to, used by the CT detection mechanism 60 to detect the product to be detected 90, such as CCD detection, etc.

[0055] In one embodiment of the present application, see Figures 1 to 3The belt mechanism 30 includes a belt 31, a first rolling member 32, a second rolling member 33 and a driving assembly 34. The second rolling member 33 cooperates with the first rolling member 32 to support the belt 31. The driving assembly 34 is used to drive the belt 31 to operate. The first rolling member 32 and the second rolling member 33 are respectively located at both ends of the base frame 20 along the length direction X. The power output end of the driving assembly 34 is connected to the belt 31 in a transmission connection, and the power output end of the telescopic mechanism 40 is connected to the second rolling member 33. The length direction X of the base frame 20 can be understood as the transmission direction of the tray 10 on the belt 31. When the telescopic mechanism 40 drives the second rolling member 33 to move in a direction away from the first rolling member 32, the second rolling member 33 can push the belt 31 to extend toward the end away from the first rolling member 32, thereby facilitating the connection with other conveying devices and realizing the continuous transmission of the tray 10 and the product 90 to be detected.

[0056] In one embodiment of the present application, see Figure 2 , Figure 3 , Figure 7 and Figure 8 The telescopic mechanism 40 includes a support seat 41 supporting the second rolling element 33 and a linear driver 42 for driving the support seat 41 to move along the length direction X of the base frame 20. The linear driver 42 is mounted on the base frame 20, and the power output end of the linear driver 42 is connected to the support seat 41. The second rolling element 33 is mounted on the support seat 41. By using the linear driver 42, the displacement of the second rolling element 33 along the length direction X of the base frame 20 can be controlled, so as to control the position of the product 90 to be detected and the tray 10.

[0057] Optionally, the linear drive 42 can be a cylinder, a linear motor, an electro-hydraulic push rod, or a motor screw nut assembly, so that the support seat 41 can be pushed to move in a straight line.

[0058] Optionally, a guide rail 411 is installed on the linear drive 42, a slider 412 is installed on the support seat 41, and the slider 412 is slidably matched with the guide rail 411; and / or, the support seat 41 is slidably matched with the base frame 20. In this way, the stability of the support seat 41 in the process of moving away from or approaching the first rolling element 32 is improved.

[0059] In one embodiment of the present application, see Figure 2 , Figure 3 , Figure 7 and Figure 8, a third rolling member 43 is installed at the free end of the telescopic mechanism 40, and the third rolling member 43 is used to push the outer ring of the belt 31 to tension the belt 31. A fourth rolling member 35 is installed at one end of the base frame 20 close to the second rolling member 33, and the fourth rolling member 35 is used to resist the inner ring of the belt 31 to tension the belt 31. The third rolling member 43 is located on the side of the fourth rolling member 35 close to the first rolling member 32; the first rolling member 32, the second rolling member 33, the third rolling member 43 and the fourth rolling member 35 are arranged in sequence along the running path of the belt 31. It should be noted that the third rolling member 43 is located on the side of the fourth rolling member 35 close to the first rolling member 32, which means that when the linear drive 42 drives the support seat 41 to move to the proximal end close to the first rolling member 32, the third rolling member 43 is located on the side of the fourth rolling member 35 close to the first rolling member 32; and when the linear drive 42 drives the support seat 41 to extend to the distal end, the positions of the third rolling member 43 and the fourth rolling member 35 along the length direction X of the base frame 20 can be substantially the same. The running path of the belt 31 can be understood as the path of a point on the belt 31 during the running process of the belt 31. By using the third rolling element 43 and the fourth rolling element 35, when the support seat 41 is away from the first rolling element 32, the length of the belt 31 between the third rolling element 43 and the fourth rolling element 35 is reduced, and the length of the belt 31 between the second rolling element 33 and the first rolling element 32 is increased, so that the tension of the belt 31 can be controlled during the extension and retraction process.

[0060] Specifically, the third rolling member 43 is rotatably mounted on the support seat 41 , so that the second rolling member 33 and the third rolling member 43 can move synchronously with the support seat 41 .

[0061] In one embodiment of the present application, see Figure 2 , Figure 3 , Figure 7 and Figure 8 , on both sides of the third rolling element 43: the belt 31 moves in the opposite direction, and the belt 31 is parallel to the length direction X of the base frame 20. It can be understood that in the process of the tray 10 moving from the first rolling element 32 to the second rolling element 33: between the third rolling element 43 and the second rolling element 33, the belt 31 moves from the second rolling element 33 to the first rolling element 32; between the third rolling element 43 and the fourth rolling element 35, the belt 31 moves from the first rolling element 32 to the first rolling element 32. When the support seat 41 moves toward the direction close to the first rolling element 32, the belt 31 between the second rolling element 33 and the first rolling element 32 is shortened, and the belt 31 between the third rolling element 43 and the fourth rolling element 35 is lengthened, so that the shortened length is equal to the lengthened length, thereby ensuring that the belt 31 can always be in a tensioned state. In this way, there is no need to set up other drive controls to tension the belt 31 during the extension and retraction of the support seat 41.

[0062] In one embodiment of the present application, see Figure 2 , Figure 3 and Figure 6 The driving assembly 34 includes a fifth rolling member 341 and a power source 342 for driving the fifth rolling member 341 to rotate. The power source 342 is installed on the base frame 20, and the power output end of the power source 342 is connected to the fifth rolling member 341. The belt 31 is wound around the fifth rolling member 341. The fifth rolling member 341 is driven to rotate by the power source 342, and then the belt 31 is driven to rotate, and the running speed and direction of the belt 31 are controlled. Optionally, the fifth rolling member 341 is located between the fourth rolling member 35 and the first rolling member 32, and the power source 342 can be an electric motor or a motor. In this way, it is convenient to arrange the installation position of the driving assembly 34.

[0063] Optionally, the driving assembly 34 further includes a driving wheel 343, a driven wheel 344, a connecting belt 345 and a mounting seat 346, the driving wheel 343 is connected to the output shaft of the power source 342, the driving wheel 343 and the driven wheel 344 cooperate to support the connecting belt 345, the driven wheel 344 is coaxially connected to the fifth rolling element 341, and the mounting seat 346 is connected to the base frame 20. In this way, the transmission between the power source 342 and the fifth rolling element 341 can be realized.

[0064] Optionally, a first roller 347 and a second roller 348 are installed on the mounting seat 346. The first roller 347 and the second roller 348 are respectively located on the belt inlet side and the belt outlet side of the fifth rolling element 341. The first roller 347 and the second roller 348 are used to increase the wrap angle of the belt 31 on the fifth rolling element 341. In this way, the friction between the belt 31 and the fifth rolling element 341 can be increased, which is beneficial to improving the control accuracy of the transmission moving distance.

[0065] Optionally, the first rolling element 32 may be a synchronous wheel, roller or guide roller, the second rolling element 33 may be a synchronous wheel, roller or guide roller, the third rolling element 43 may be a synchronous wheel, roller or guide roller, and the fourth rolling element 35 may be a synchronous wheel, roller or guide roller. In this way, it is convenient to support the belt 31 and guide the belt 31 to run.

[0066] In one embodiment of the present application, see Figure 2 , Figure 3 and Figure 6 The number of the belts 31 is two, and the two belts 31 are respectively located on opposite sides of the base frame 20 along the width direction Y. In this way, the two sides of the tray 10 can be supported respectively, which helps to ensure the synchronization of the operation of the two sides of the tray 10.

[0067] Optionally, there are two first rollers 32, which are coaxially arranged and correspond to two belts 31 respectively; there are two second rollers 33, which are coaxially arranged and correspond to two belts 31 respectively; there are two third rollers 43, which are coaxially arranged and correspond to two belts 31 respectively; there are two fourth rollers 35, which are coaxially arranged and correspond to two belts 31 respectively. In this way, it is helpful to ensure the consistency of the operation of the two belts 31.

[0068] Optionally, there are two fifth rollers 341, the two fifth rollers 341 are coaxially connected, and the two fifth rollers 341 correspond to the two belts 31 respectively; there are two first rollers 347, the two first rollers 347 are coaxially arranged, and the two first rollers 347 correspond to the two belts 31 respectively; there are two second rollers 348, the two second rollers 348 are coaxially arranged, and the two second rollers 348 correspond to the two belts 31 respectively. In this way, it is helpful to ensure that the two belts 31 run in unison, so that both sides of the tray 10 can be pulled by the belts 31 when the tray 10 is transported.

[0069] In one embodiment of the present application, please refer to Figures 1 to 3 The belt mechanism 30 further includes a sixth rolling member 36, which is mounted on one end of the base frame 20 close to the first rolling member 32, and the sixth rolling member 36 is located below the first rolling member 32. In this way, the distance between the upper and lower sides of the belt 31 can be increased, and the stability of the belt 31 during operation can be improved.

[0070] Optionally, there are two sixth rolling members 36 , the two sixth rolling members 36 are coaxially arranged, and the two sixth rolling members 36 correspond to the two belts 31 , respectively. In this way, it is helpful to keep the two belts 31 synchronous.

[0071] In one embodiment of the present application, see Figure 3 , Figure 7 and Figure 8 The transmission device 100 further includes a lifting assembly 44, which includes a lifting frame 441 for carrying the pallet 10 to be lifted and lowered, and a first lifting driver 442 for driving the lifting frame 441 to be lifted and lowered. The first lifting driver 442 is installed at the power output end of the telescopic mechanism 40, and the power output end of the first lifting driver 442 is connected to the lifting frame 441. When the pallet 10 moves above the lifting frame 441, the first lifting driver 442 can drive the lifting frame 441 to rise, thereby lifting the pallet 10, and the pallet 10 is separated from the belt 31, thereby ensuring the stability of the position of the pallet 10.

[0072] Optionally, the first lifting driver 442 may be a cylinder, a linear motor or an electro-hydraulic push rod, etc., so that the lifting frame 441 can be controlled to move along the vertical direction Z.

[0073] In one embodiment of the present application, see Figure 3 , Figure 7 and Figure 8 A non-return hook 45 for stopping the tray 10 is installed on the telescopic mechanism 40. The non-return hook 45 can prevent the tray 10 from moving in the direction close to the first rolling member 32, so as to control the position of the tray 10 along the length direction X of the base frame 20.

[0074] In one embodiment of the present application, see Figure 3 , Figure 7 and Figure 8 The transmission device 100 further includes a positioning assembly 46, which includes a positioning hook 461 for stopping the tray 10 and a second lifting driver 462 for driving the positioning hook 461 to move up and down. The second lifting driver 462 is installed at the power output end of the telescopic mechanism 40, and the power output end of the second lifting driver 462 is connected to the positioning hook 461. The positioning hook 461 can be used to locate the position of the tray 10 away from the side of the first rolling element 32. The positioning hook 461 can cooperate with the non-return hook 45 to locate the position of the tray 10.

[0075] Optionally, the second lifting driver 462 may be a cylinder or a linear motor, etc., so that the positioning hook 461 can be controlled to move along the vertical direction Z.

[0076] Optionally, a positioning step 4410 is provided on the lifting frame 441 at a position corresponding to the non-return hook 45. When the first lifting driver 442 drives the lifting frame 441 to rise and the second lifting driver 462 drives the positioning hook 461 to rise, the positioning step 4410 cooperates with one side of the positioning tray 10 and the positioning hook 461 cooperates with the other side of the positioning tray 10. In this way, the movement of the tray 10 along the length direction X of the base frame 20 can be restricted, and the stability of the position of the tray 10 after the lifting can be controlled.

[0077] Optionally, a positioning column is provided on the lifting frame 441, and a positioning hole is provided at the bottom of the tray 10, and the positioning hole is used for the positioning column to be inserted. In this way, it is convenient to control the stability of the position of the tray 10 on the lifting frame 441. There can be multiple positioning columns, which is conducive to improving the position accuracy and stability of the tray 10.

[0078] In one embodiment of the present application, see Figures 1 to 3 The transmission device 100 further includes a tray 10, and the tray 10 is used to carry and move the product to be detected 90. By using the belt 31 to transmit the tray 10, the position and angle of the product to be detected 90 can be conveniently controlled.

[0079] In one embodiment of the present application, see Figures 2 to 5 The tray 10 includes a base plate 11, a positioning plate 12, a guide assembly 13, an elastic member 14, a bearing 15 and a fixed seat 16. The fixed seat 16 is used to accommodate the product 90 to be detected. The fixed seat 16 is rotatably connected to the base plate 11 through the bearing 15. The positioning plate 12 is slidably connected to the base plate 11 through the guide assembly 13. The guide assembly 13 is used to push the fixed seat 16 so that the angle position of the relative rotation between the fixed seat 16 and the base plate 11 remains fixed. The positioning plate 12 is located between the base plate 11 and the fixed seat 16; the elastic member 14 is installed on the base plate 11, and the elastic member 14 is connected to the positioning plate 12 to push the positioning plate 12 to abut against the fixed seat 16. In this way, the fixed seat 16 can be rotated by external force to adjust the angle of the product 90 to be detected, which is convenient for the detection of the product 90 to be detected. After the external force is removed, the elastic member 14 pushes the positioning plate 12 to abut against the fixed seat 16 to hinder the rotation of the fixed seat 16 and keep the angle of the product 90 to be detected stable.

[0080] Optionally, there are multiple guide assemblies 13, and the multiple guide assemblies 13 are arranged in an array, for example, there are four guide assemblies 13, and the four guide assemblies 13 are arranged in a rectangular array.

[0082] Optionally, the elastic member 14 is a spring, and two ends of the spring are respectively in contact with the positioning plate 12 and the base plate 11 . In this way, the positioning plate 12 can be pushed away from the base plate 11 , so that the positioning plate 12 is held against the lower surface of the fixing seat 16 .

[0083] Optionally, a friction sheet 17 is installed on one side of the positioning plate 12 close to the fixing seat 16, and the friction sheet 17 is used to frictionally cooperate with the bottom surface of the fixing seat 16. The friction sheet 17 can be a sheet material with a large surface friction coefficient such as a rubber sheet or a silicone sheet. In this way, the friction force can be increased and the stability of the product to be detected at a 90-degree angle can be improved.

Figure 4 The stopper 111 is used for engaging with an external mechanism to limit the rotation of the substrate 11 when the fixing seat 16 is rotated. In this way, the angle of the fixing seat 16 can be easily rotated.

[0085] Optionally, the positioning hook 461 is used to stop the positioning stop block 111, so that when the tray 10 stops, the front end of the product 90 to be inspected can extend out of the telescopic mechanism 40 for easy inspection.

In this way, when the third lifting driver 52 drives the stop block 51 to rise, the stop block 51 can block the positioning block 111 to locate the position of the tray 10. At this time, the fixed seat 16 on the tray 10 can be rotated to adjust the angle of the product 90 to be detected. Optionally, the third lifting driver 52 can be a cylinder or a linear driver, so that the stop block 51 can be controlled to move along the vertical direction Z.

In this way, the functions of the belt mechanism 30 and the telescopic mechanism 40 can be separated independently, and the actions can be flexibly coordinated to improve efficiency; the first base and the second base are independent of each other, so as to avoid vibration caused by the connection of the transmission device 100 or other interference with the battery cell and affect the detection imaging.

In this way, the product 90 to be detected at the end of the upstream transmission device 100 and the product 90 to be detected at the head end of the downstream transmission device 100 can be detected at the same time, and both ends of the product 90 to be detected can be detected, which is conducive to improving the detection efficiency. The structures of the two transmission devices 100 can be different, as long as the continuous transmission of the tray 10 can be achieved.

[0097] Load the product 90 to be inspected into the tray 10, place the tray 10 on the belt mechanism 30, and transfer the tray 10 and the product 90 to be inspected to the CT inspection mechanism 60 through the belt mechanism 30, and the telescopic mechanism 40 is in a retracted state;

[0098] When the tray 10 reaches one end of the base frame 20 close to the CT detection mechanism 60, the positioning hook 461 rises to stop the stop block 111 of the positioning tray 10, and the non-return hook 45 stops the tray 10 from being away from the end of the CT detection mechanism 60, so that the position of the tray 10 and the support seat 41 remain stable;

[0099] The first lifting driver 442 drives the lifting frame 441 to rise, and the positioning column cooperates to be inserted into the positioning hole at the bottom of the tray 10; the positioning step 4410 positions the tray 10 away from the side of the CT detection mechanism 60, so that the tray 10 is separated from the belt 31 and the position of the tray 10 is kept stable; the positioning hook 461 descends to a low position;

[0100] At this time, the CT detection mechanism 60 can scan and detect the products to be detected 90; when the downstream transmission device 100 close to one end of the CT detection mechanism 60 is also locked with the tray 10 carrying the products to be detected 90, the CT scanning mechanism 60 can scan and detect the two products to be detected 90 inserted therein at the same time;
