Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to an X-ray battery inspection device and its inspection method. Background Technology

[0002] X-ray inspection is a crucial step in battery production. A direct testing method is typically used, where the battery to be inspected is placed in front of an X-ray source. The X-rays irradiate the battery before reaching the X-ray detector. Because the positive and negative electrode materials inside the battery differ in thickness and overlap, their absorption of X-rays varies, resulting in different intensities of the X-rays after passing through the battery. The X-ray detector uses these intensities to map the internal morphology of the battery and measure the alignment of the positive and negative electrodes. Currently, on battery production lines, to improve production efficiency, batteries are typically placed in batches in fixtures and transported by conveyor belt to the inspection device for continuous testing.

[0003] However, on the battery transport line, since the batteries are not fixed to the fixture, they may shift or tilt during the transfer process, which can cause vibration interference when X-rays are used to inspect internal defects in the batteries, thus affecting the accuracy of the inspection results.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

Detailed Implementation

[0059] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0064] See Figure 1 and Figure 5 In one embodiment of this invention application, an X-ray battery detection device is disclosed, including a support platform 10, a conveyor belt 20, an X-ray emitter 30, an image receiver 40, a clamping assembly 50, and an abutment assembly 60. The conveyor belt 20 is disposed on the support platform 10; the conveyor belt 20 is used to transport a fixture 80 on which a battery 90 is placed; the X-ray emitter 30 is disposed on one side of the conveyor belt 20 and is used to emit a detection beam toward the battery 90 on the fixture 80; the image receiver 40 is disposed on the other side of the conveyor belt 20 and is disposed opposite to the X-ray emitter 30, and is used to collect detection light signals.

[0065] After being packaged, the batteries 90 manufactured on the production line are uniformly loaded into fixture 80 and then transferred to conveyor belt 20 for automatic inspection. In this embodiment, the conveyor belt 20 on the support platform 10 is driven by a motor or electric cylinder and can be set horizontally to smoothly transport the fixture 80 to the position between the X-ray emitter 30 and the image receiver 40. The X-ray beam penetrates the battery 90, allowing for precise inspection of the product to achieve quality control. After inspection, the battery continues to be transported to the next workstation by the conveyor belt 20. To improve stability during transportation and inspection, clamping components 50 and abutment components 60 are provided to constrain the fixture 80 onto the conveyor belt 20.

[0066] like Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly 50 includes a first clamping head 51 and a second clamping head 52, which extend to both sides of the conveyor belt 20 respectively. The first clamping head 51 and the second clamping head 52 can move towards each other to clamp the fixture 80. The abutment assembly 60 is connected to the clamping assembly 50, is disposed on the side of the conveyor belt 20, and partially extends to the top of the conveyor belt 20 to abut the battery 90 on the fixture 80 downwards.

[0067] In this embodiment, when the fixture 80 moves on the conveyor belt 20, the first clamping head 51 and the second clamping head 52 abut against the two sides of the fixture 80 to achieve lateral fixation. The abutting component 60 abuts against the top surface of the battery 90 to press the battery 90 into the fixture 80. At the same time, the fixture 80 is pressed onto the conveyor belt 20 to achieve longitudinal fixation.

[0068] In summary, this embodiment uses clamping components 50 to clamp the fixture 80 from both sides and abutting components 60 to abut the battery 90 from above, ensuring stability between the fixture 80 and the battery 90 on the conveyor belt 20. This allows for synchronous operation with the conveyor belt 20, moving the battery 90 between the X-ray emitter 30 and the image receiver 40 for inspection. This reduces issues such as battery offset or tilting, increases inspection accuracy and validity, reduces the probability of false alarms, and avoids wasting production costs. After inspection, the clamping components 50 and abutting components 60 are released, allowing the conveyor belt 20 to continue transporting the fixture 80 to subsequent workstations.

[0069] See Figure 2 and Figure 3 As one embodiment of this invention, the clamping assembly 50 includes a support base 53, a first guide rail 54, a first clamping plate 55, a first driving member 56, and a second clamping plate 57. The first guide rail 54 is disposed on the support base 53. The extension direction of the first guide rail 54 is perpendicular to the transport direction of the conveyor belt 20. One end of the first clamping plate 55 is slidably disposed on the first guide rail 54, and the other end is provided with a first clamping head 51. The first driving member 56 is disposed on the support base 53. The first driving member 56 is drively connected to the first clamping plate 55. One end of the second clamping plate 57 is connected to the support base 53 and located at the end of the first guide rail 54, and the other end is provided with a second clamping head 52.

[0070] In this embodiment, the support base 53 is arranged around the support platform 10, preferably below the support platform 10. The second clamping plate 57 is fixed to the support base 53, and the top end of the second clamping plate 57 extends upward to the side of the conveyor belt 20. The first clamping plate 55 is movably arranged on the first guide rail 54, and the top end of the first clamping plate 55 extends upward to the other side of the conveyor belt 20, so that the first clamping head 51 and the second clamping head 52 are arranged opposite to each other. The first driving member 56 includes, but is not limited to, a motor, engine, etc., which drives the first clamping plate 55 to move back and forth on the first guide rail 54, thereby adjusting the space between the first clamping head 51 and the second clamping head 52, and realizing the clamping operation of the fixture 80 on the conveyor belt 20.

[0071] By automatically controlling the distance between the first clamping head 51 and the second clamping head 52, the clamping action can be completed flexibly, which is beneficial to accurately and stably constrain the fixture 80 and improve the stability of the fixture 80 as it moves with the conveyor belt 20.

[0072] In addition, the distance between the first clamping head 51 and the second clamping head 52 is adjustable, so it can clamp jigs 80 of different sizes, which is highly adaptable, increases the types of batteries 90 that can be detected, and improves the use value of the X-ray battery detection device.

[0073] like Figure 2 and Figure 3 As shown, in another embodiment of this invention, the support base 53 includes a support frame 531, a sliding base 533, and a second driving member 534. The support frame 531 is provided with a second guide rail 532, the extension direction of which is parallel to the transport direction of the conveyor belt 20. The sliding base 533 is slidably disposed on the second guide rail 532. The second driving member 534 is disposed on the support frame 531 and is drively connected to the sliding base 533. The first guide rail 54 is disposed on the sliding base 533 and extends along the radial direction of the sliding base 533.

[0074] In this embodiment, a sliding base 533 is provided to support the first guide rail 54, the first clamping plate 55, the first driving component 56, the second clamping plate 57, etc. The second driving component 534 includes, but is not limited to, a stepper motor. The sliding base 533 is driven to move by the second driving component 534, so that the first clamping plate 55 and the second clamping plate 57 can move synchronously along the transport direction of the conveyor belt 20, thereby achieving the effect of moving laterally with the jig 80 in sync with the conveyor belt 20.

[0075] During the testing process, such as Figure 5 As shown, if there is more than one battery 90 on fixture 80, or as... Figure 1As shown, multiple fixtures 80 are clamped simultaneously between the first clamping head 51 and the second clamping head 52, requiring batch testing of multiple batteries 90. To maintain a stable testing path and keep the X-ray emitter 30 and image receiver 40 stationary, the fixtures 80 need to be moved between adjacent tests to adjust the position of the batteries 90 to be tested. In this embodiment, the moving speeds of the first clamping plate 55, the second clamping plate 57, and the conveyor belt 20 can be controlled to be the same, allowing the fixtures 80 to move stably laterally while clamped, preventing relative friction with the conveyor belt 20. This improves the accuracy of continuous battery 90 testing, facilitates batch processing, and increases work efficiency.

[0076] For example Figure 2 and Figure 3 As shown, in another embodiment of this invention, the abutment component 60 includes a longitudinal support plate 61, a sliding block 63, an abutment member 64, and a third driving member. The longitudinal support plate 61 is vertically disposed on the top of the first clamping head 51 or the second clamping head 52. A longitudinally extending third guide rail 62 is provided on the longitudinal support plate 61 facing the conveyor belt 20. One side of the sliding block 63 is slidably disposed on the third guide rail 62, and the other side extends laterally to directly above the conveyor belt 20, forming an assembly platform 631. The abutment member 64 is disposed on the assembly platform 631 and is used to abut against the battery 90 on the fixture 80. The third driving member is disposed on the longitudinal support plate 61 and is drively connected to the sliding block 63.

[0077] In this embodiment, the longitudinal support plate 61 is disposed on the first clamping head 51 or the second clamping head 52, so it can extend upward from the side of the conveyor belt 20 to above the conveyor belt 20, so that the sliding block 63 can extend laterally to directly above the conveyor belt 20, thereby allowing the abutment member 64 to be vertically aligned with the battery 90 for abutment against the battery 90. In addition, if the sliding base 533 is provided, when the first clamping plate 55 and the second clamping plate 57 move, the abutment component 60 will also move together with the fixture 80 along the transport direction of the conveyor belt 20, thereby maintaining both the compressive force on the side of the fixture 80 and the downward pressure on the fixture 80, so that the fixture 80 remains stable.

[0078] Specifically, in this embodiment, the third driving component includes, but is not limited to, a hydraulic press or a motor. By driving the sliding block 63 to slide on the third guide rail 62, the height of the abutment 64 is accurately controlled. When the fixture 80 moves to the position to be inspected, the abutment 64 can be pressed down to contact the battery 90. When the inspection is completed, the abutment 64 can be raised to release the battery 90, allowing for continued transport to the next station. Furthermore, the height of the abutment 64 can be adjusted to accommodate different types of fixtures 80 and batteries 90, thereby increasing the applicability and usability of the X-ray battery inspection device.

[0079] See Figure 2 As another embodiment of this invention, the longitudinal support plate 61 is disclosed to include a telescopic part 611 and a connecting part 612. One end of the telescopic part 611 is connected to the first clamping head 51 or the second clamping head 52, and the other end can extend and retract vertically to above the conveyor belt 20. The connecting part 612 is disposed at the top end of the telescopic part 611. The third guide rail 62 is disposed on the connecting part 612.

[0080] In this embodiment, the telescopic part 611 is set as a multi-section telescopic rod or a multi-section folding rod, so that the height of the connecting part 612 can be adjusted to adapt to the height of the testing fixture 80, so that the position of the connecting part 612 is higher than the top surface of the fixture 80, so that the assembly platform 631 can be set directly above the fixture 80, so as to facilitate the assembly of the abutment part 64 and the pressing of the battery 90.

[0081] Specifically, the abutment member 64 disclosed in this embodiment can be configured as a retractable elastic member, thereby achieving elastic contact when abutting the battery 90, reducing hard impact and avoiding damage to the battery 90. Additionally, the bottom end of the abutment member 64 can be provided with a contact end made of flexible material such as a rubber head or latex head to further buffer the squeezing force, protect the battery 90, and prevent crushing. In another embodiment of this embodiment, a longitudinally penetrating through hole can be provided on the assembly platform 631, and the abutment member 64 can be inserted into the through hole; a baffle is provided around the side wall of the abutment member 64, and a spring is sleeved on the abutment member 64. One end of the spring abuts against the assembly platform 631, and the other end abuts against the baffle, so that the abutment member 64 always maintains a downward moving trend, thereby achieving the effect of pressing against the battery 90. This also achieves the pressing effect and reduces squeezing damage.

[0082] See Figure 5 In another embodiment of this invention, the fixture 80 is disclosed to be elongated, and a plurality of mounting holes 81 are provided along its length for assembling batteries 90. Assembling multiple batteries 90 at once facilitates batch transportation and testing, improves production efficiency, and reduces the use of the fixture 80.

[0083] Specifically, the assembly platform 631 is elongated, and its length direction is parallel to the transport direction of the conveyor belt 20. Multiple assembly holes 632 are arranged linearly along the length direction on the assembly platform 631, and the assembly holes 632 are used to insert the abutment 64. The spacing between two adjacent assembly holes 632 is equal to the spacing between two adjacent mounting holes 81.

[0084] In this embodiment, the abutting member 64 abuts against each of the batteries 90, so that each battery 90 on the fixture 80 remains stable. At the same time, there are multiple pressing contact points on the fixture 80 along the direction of movement, thereby improving the overall stability and making it less prone to lateral deviation.

[0085] For example Figure 1 As shown, in another embodiment of this invention, the X-ray cell detection device includes at least one set of blocking and positioning components 70. The blocking and positioning components 70 are disposed on the support platform 10 and located on the side of the conveyor belt 20, and are used to abut against the fixture 80.

[0086] In this embodiment, the fixture 80 is limited by the blocking and positioning component 70. Specifically, the blocking and positioning component 70 is positioned in front of the clamping component 50 along the transport direction of the conveyor belt 20. Before detection, the fixture 80 is positioned so that it stops at a predetermined position. Then, the first clamping head 51 and the second clamping head 52 can accurately clamp the fixture 80, thereby improving the accuracy of the clamping component 50.

[0087] Specifically, as another implementation of this embodiment, multiple sets of the blocking positioning components 70 are disclosed, and the multiple sets of blocking positioning components 70 are arranged at intervals along the transport direction of the conveyor belt 20, and a detection interval is formed between two adjacent sets of blocking positioning components 70; multiple X-ray emitters 30 are provided, multiple image receivers 40 are provided, and each detection interval is provided with an X-ray emitter 30 and an image receiver 40.

[0088] For example Figure 1 As shown, in this embodiment, by setting multiple X-ray emitters 30 and image receivers 40, batteries 90 on multiple fixtures 80 can be detected simultaneously, further improving detection efficiency. Multiple sets of blocking and positioning components 70 are set up to ensure that the fixtures 80 arranged sequentially on the conveyor belt 20 enter the detection zone at a predetermined distance, thereby enabling orderly detection and preventing batteries 90 on a single fixture 80 from being repeatedly detected or from being missed.

[0089] Specifically, in this embodiment, multiple sets of clamping components 50 and abutment components 60 can be set, corresponding to the X-ray emitter 30; in other words, clamping components 50 and abutment components 60 are set in each detection interval to ensure that each fixture 80 remains stable during detection. When the sliding base 533 is set, multiple first guide rails 54, multiple first clamping plates 55, and multiple second clamping plates 57 can be set for each detection interval, thereby clamping multiple fixtures 80 simultaneously, moving synchronously with the conveyor belt 20, and detecting synchronously, thus improving detection efficiency.

[0090] like Figure 4As shown, in another embodiment of this invention, the blocking and positioning assembly 70 includes a connecting platform 71, a stop block 72, and a hydraulic transmission rod 73. The connecting platform 71 is connected to the support platform 10 and is disposed on the side of the conveyor belt 20. A fourth guide rail 711 is provided on the top surface of the connecting platform 71, and the fourth guide rail 711 extends toward the conveyor belt 20. The stop block 72 is slidably disposed on the fourth guide rail 711. The hydraulic transmission rod 73 is disposed on the connecting platform 71 and connected to the stop block 72. The hydraulic transmission rod 73 is used to connect an external hydraulic press to drive the stop block 72 to move toward or away from the conveyor belt 20. A docking groove 82 is provided on the side of the fixture 80, and the stop block 72 is adapted to the docking groove 82.

[0091] Before testing, the hydraulic transmission rod 73 disclosed in this embodiment drives the stop block 72 to move toward the conveyor belt 20. When the fixture 80 moves, the stop block 72 inserts into the docking groove 82, and the rear end of the docking groove 82 is closed. When the stop block 72 contacts the rear wall of the docking groove 82, it constrains the fixture 80, causing the fixture 80 to stop moving, which facilitates the clamping assembly 50 and the abutment assembly 60 to stabilize the fixture 80. After the fixture 80 is clamped, the stop block 72 moves in the opposite direction and can disengage from the docking groove 82. The fixture 80 can then continue to move with the conveyor belt 20 together with the clamping assembly 50 and the abutment assembly 60 for testing.

[0092] It should be noted that this embodiment is only an example of using a hydraulic transmission rod 73 to drive the stop 72 to move, but it is not an exhaustive list. The stop 72 can also be driven by other means, such as motor transmission. As an equivalent substitution of the inventive concept, it should also be within the scope of protection of this application.

[0093] See Figure 6 As another embodiment of this application, an X-ray cell detection method is disclosed, applied to any of the X-ray cell detection devices described above; wherein, it includes:

[0094] S100, Install the battery 90 to be tested onto the fixture 80;

[0095] S200, Move the fixture 80 to the conveyor belt 20;

[0096] S300: Start the conveyor belt 20 to transport the fixture 80 between the X-ray emitter 30 and the image receiver 40;

[0097] S400, tighten the clamping component 50 and move it down to abut the component 60 to complete the pre-detection positioning;

[0098] S500: Start the X-ray emitter 30 and the image receiver 40 to collect detection data.

[0099] In this embodiment, by clamping and holding the fixture 80 before testing, the battery 90 on the fixture 80 is clamped, achieving the effect of pre-test positioning. This ensures that the position of each battery 90 is basically the same during the testing process, improving the accuracy of the test and thus increasing the effectiveness of the test results.

[0100] In summary, this application discloses an X-ray battery detection device, comprising a support platform 10, a conveyor belt 20, an X-ray emitter 30, an image receiver 40, a clamping assembly 50, and an abutment assembly 60. The conveyor belt 20 is disposed on the support platform 10; the conveyor belt 20 is used to transport a fixture 80 holding a battery 90; the X-ray emitter 30 is disposed on one side of the conveyor belt 20 and is used to emit a detection beam toward the battery 90 on the fixture 80; the image receiver 40 is disposed on the other side of the conveyor belt 20 and is connected to the X-ray emitter 30. Line transmitters 30 are arranged opposite each other for collecting and detecting optical signals; the clamping assembly 50 includes a first clamping head 51 and a second clamping head 52, the first clamping head 51 and the second clamping head 52 respectively extend to both sides of the conveyor belt 20, the first clamping head 51 and the second clamping head 52 can move towards each other for clamping the fixture 80; the abutment assembly 60 is connected to the clamping assembly 50, is disposed on the side of the conveyor belt 20, and partially extends to the top of the conveyor belt 20 for abutting downwards against the battery 90 on the fixture 80. By setting the clamping assembly 50 to clamp the fixture 80 from both sides and the abutment assembly 60 to abut the battery 90 from above, the fixture 80 on the conveyor belt 20 and the battery 90 to be tested are kept stable. This allows the fixture 80 to work synchronously with the conveyor belt 20 to move the battery 90 between the X-ray emitter 30 and the image receiver 40 for testing. This reduces problems such as battery 90 offset or tilting, increases the accuracy of testing, improves the effectiveness of testing results, reduces the probability of false alarms, and avoids wasting production costs.
