Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing, and in particular to an X-ray battery detection device and a detection method thereof. Background Art

[0002] In the battery production process, X-ray detection is a crucial link. Generally, a direct test method is used, that is, the battery to be tested is placed in front of the X-ray emission source, and the X-rays irradiate the battery to be tested and then reach the X-ray detector. Since the positive and negative electrode materials inside the battery are different, the overlapping thickness is different, and the absorption of X-rays is different, the intensity of the X-rays after passing through the battery is different. The X-ray detector can draw the internal morphology of the battery to be tested according to the different intensities of the detected X-rays, and then measure the alignment of the positive and negative electrodes in the battery. At present, on the battery production line, in order to improve the production efficiency of the battery, the batteries are generally placed in batches in a jig and transported to the detection device by a conveyor belt for continuous testing.

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

[0065] After the batteries 90 manufactured on the production line are packaged, they are uniformly loaded into the jig 80 and then transferred to the conveyor belt 20 for automatic inspection. In this embodiment, the conveyor belt 20 on the support table 10 is driven by a motor or an electric cylinder and can be set horizontally to smoothly transport the jig 80 to the position between the X-ray emitter 30 and the image receiver 40. After the X-ray beam penetrates the battery 90, the product is accurately inspected to achieve the purpose of quality inspection. After the inspection is completed, it will continue to be transported to the subsequent workstation by the conveyor belt 20. In order to improve the stability during transportation and inspection, a clamping assembly 50 and an abutment assembly 60 are set to constrain the jig 80 on 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, and the first clamping head 51 and the second clamping head 52 extend to both sides of the conveyor belt 20 respectively. The first clamping head 51 and the second clamping head 52 can move toward each other to clamp the jig 80; the abutment assembly 60 is connected to the clamping assembly 50, is arranged on the side of the conveyor belt 20, and partially extends to the top of the conveyor belt 20, and is used to abut the battery 90 on the jig 80 downward.

[0067] In this embodiment, when the jig 80 moves on the conveyor belt 20, the first clamping head 51 and the second clamping head 52 abut against both sides of the jig 80 to achieve lateral fixation, and the abutment assembly 60 abuts against the top surface of the battery 90, thereby pressing the battery 90 into the jig 80 and pressing the jig 80 onto the conveyor belt 20 to achieve longitudinal fixation.

[0068] In summary, this embodiment provides a clamping assembly 50 to clamp the jig 80 from both sides, and provides an abutment assembly 60 to abut the battery 90 from above, so that the jig 80 on the conveyor belt 20 and the battery 90 to be tested remain stable, so that it can cooperate synchronously with the conveyor belt 20 to move the battery 90 between the X-ray emitter 30 and the image receiver 40 for testing, reduce the problem of the battery 90 being offset or tilted, increase the accuracy of the test, improve the effectiveness of the test results, reduce the probability of false positives, and avoid wasting production costs. After the test, the clamping assembly 50 and the abutment assembly 60 are released, and the conveyor belt 20 can continue to transport the jig 80 to the subsequent station.

[0069] See also Figure 2 and Figure 3 As an implementation mode of this embodiment, it is disclosed that the clamping assembly 50 includes a support seat 53, a first guide rail 54, a first clamping plate 55, a first driving member 56 and a second clamping plate 57, wherein the first guide rail 54 is arranged on the support seat 53; the extension direction of the first guide rail 54 is perpendicular to the transportation direction of the conveyor belt 20; one end of the first clamping plate 55 is slidably arranged on the first guide rail 54, and the other end is provided with the first clamping head 51; the first driving member 56 is arranged on the support seat 53; the first driving member 56 is transmission-connected to the first clamping plate 55; one end of the second clamping plate 57 is connected to the support seat 53, located at the end of the first guide rail 54, and the other end is provided with the second clamping head 52.

[0070] In this embodiment, the support seat 53 is arranged around the support platform 10, preferably below the support platform 10, and the second clamping plate 57 is fixed on the support seat 53, and the top of the second clamping plate 57 extends upward to the side of the conveyor belt 20, and the first clamping plate 55 is movably arranged on the first guide rail 54, and the top 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 oppositely. The first driving member 56 includes but is not limited to a motor, an engine, etc., and drives the first clamping plate 55 to move forward and backward 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 jig 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 flexibly completed, which is beneficial for accurately and stably restraining the jig 80 and improving the stability of the jig 80 moving 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 that different sizes of fixtures 80 can be clamped, the adaptability is strong, the types of batteries 90 that can be detected are increased, and the use value of the X-ray battery detection device is improved.

[0073] like Figure 2 and Figure 3 As shown, as another implementation of this embodiment, it is disclosed that the support seat 53 includes a support frame 531, a sliding base 533 and a second driving member 534, and the support frame 531 is provided with a second guide rail 532, and the extension direction of the second guide rail 532 is parallel to the transportation direction of the conveyor belt 20; the sliding base 533 is slidably arranged on the second guide rail 532; the second driving member 534 is arranged on the support frame 531 and is transmission-connected to the sliding base 533; the first guide rail 54 is arranged 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 carry the first guide rail 54, the first clamping plate 55, the first driving member 56, the second clamping plate 57, etc. The second driving member 534 includes but is not limited to a stepping motor. The sliding base 533 is driven to move by the second driving member 534, so that the first clamping plate 55 and the second clamping plate 57 can be moved synchronously along the transportation direction of the conveyor belt 20, thereby achieving the effect of synchronously following the lateral movement of the conveyor belt 20 with the jig 80.

[0075] During the testing process, Figure 5 As shown, if there is more than one battery 90 on the fixture 80, or as Figure 1As shown, multiple jigs 80 are clamped between the first clamping head 51 and the second clamping head 52 at one time, and batch detection of multiple batteries 90 is required. While maintaining the stability of the detection route and the X-ray emitter 30 and the image receiver 40 are not moving, it is necessary to move the jig 80 in the interval between two adjacent detections to adjust the position of the battery 90 to be detected. 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, so that the jig 80 can move stably laterally when being clamped, and there will be no relative friction between the conveyor belt 20, thereby improving the accuracy of continuous battery 90 detection, facilitating batch work, and improving work efficiency.

[0076] For example Figure 2 and Figure 3 As shown, as another implementation of the present embodiment, the abutment assembly 60 is disclosed to include a longitudinal support plate 61, a sliding block 63, an abutment member 64 and a third driving member, wherein the longitudinal support plate 61 is vertically arranged 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 on the side facing the conveyor belt 20; one side of the sliding block 63 is slidably arranged on the third guide rail 62, and the other side extends laterally to directly above the conveyor belt 20 to form an assembly platform 631; the abutment member 64 is arranged on the assembly platform 631, and is used to abut the battery 90 on the fixture 80; the third driving member is arranged on the longitudinal support plate 61, and is transmission-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 that it can extend upward from the side of the conveyor belt 20 to the top of the conveyor belt 20, so that the sliding block 63 can extend horizontally to the top of the conveyor belt 20, so that the abutment member 64 can be aligned with the battery 90 up and down, so as to abut the battery 90. In addition, if a sliding base 533 is provided, when the first clamping plate 55 and the second clamping plate 57 move, the abutment assembly 60 will also move along the transport direction of the conveyor belt 20 with the jig 80, thereby maintaining both the squeezing force on the side of the jig 80 and the downward pressure on the jig 80, so that the jig 80 remains stable.

[0078] Specifically, in this embodiment, the third driving member includes but is not limited to a hydraulic press or a motor, which drives the sliding block 63 to slide on the third guide rail 62 to accurately control the height of the abutment 64. When the fixture 80 moves to the position to be detected, the abutment 64 can be pressed down to contact the battery 90; when the detection is completed, the abutment 64 can be raised to release the battery 90 to continue transporting it to the next station. In addition, the height of the abutment 64 can be adjusted to adapt to different types of fixtures 80 and batteries 90, thereby increasing the scope of application of the X-ray battery detection device and increasing its use value.

[0079] See also Figure 2 As another implementation of this embodiment, it is disclosed that the longitudinal support plate 61 includes a telescopic portion 611 and a connecting portion 612, one end of the telescopic portion 611 is connected to the first clamping head 51 or the second clamping head 52, and the other end can be telescoped in the vertical direction to the top of the conveyor belt 20; the connecting portion 612 is arranged at the top end of the telescopic portion 611; and the third guide rail 62 is arranged on the connecting portion 612.

[0080] In this embodiment, the telescopic portion 611 is configured as a multi-section telescopic rod or a multi-section folding rod, so that the height of the connecting portion 612 can be adjusted to adapt to the height of the detection fixture 80, so that the position of the connecting portion 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 to facilitate the assembly of the abutment 64 and press the battery 90.

[0081] Specifically, the abutment member 64 disclosed in this embodiment can be set as a retractable elastic member, so that elastic contact occurs when abutting the battery 90, reducing hard collisions and avoiding damage to the battery 90. In addition, the bottom end of the abutment member 64 can be provided with a contact terminal made of flexible materials such as a rubber head and a latex head to further buffer the extrusion force, protect the battery 90, and avoid crushing. In another implementation of this embodiment, a longitudinal 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, so that one end of the spring abuts the assembly platform 631, and the other end abuts the baffle, so that the abutment member 64 always maintains a downward movement trend, thereby achieving the effect of pressing the battery 90, which can also achieve a pressing effect and reduce extrusion damage.

[0082] See also Figure 5 As another implementation of this embodiment, the shape of the jig 80 is disclosed as a long strip, and a plurality of mounting holes 81 are provided on the jig 80 along the length direction, and the mounting holes 81 are used to assemble batteries 90. By assembling a plurality of batteries 90 at one time, it is convenient for batch transportation and testing, improves production efficiency, and reduces the use of jigs 80.

[0083] Specifically, the assembly platform 631 is in the shape of a long strip, and the length direction of the assembly platform 631 is parallel to the transport direction of the conveyor belt 20; a plurality of assembly holes 632 are arranged in a linear array along the length direction on the assembly platform 631, and the assembly holes 632 are used to plug in 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 abutment members 64 abut against the batteries 90 one by one, so that each battery 90 on the fixture 80 remains stable. At the same time, there are multiple extrusion contact points on the fixture 80 along the movement direction, thereby improving the overall stability and preventing side deviation.

[0085] For example Figure 1 As shown, as another implementation of this embodiment, the X-ray battery detection device is disclosed to include at least one group of blocking positioning components 70, and the blocking positioning components 70 are arranged on the support platform 10, located on the side of the conveyor belt 20, for abutting the fixture 80.

[0086] In this embodiment, the jig 80 is limited by the blocking and positioning assembly 70. Specifically, along the transport direction of the conveyor belt 20, the blocking and positioning assembly 70 is arranged in front of the clamping assembly 50, and before the detection, the jig 80 is positioned so that the jig 80 stays at a predetermined position, and then the first clamping head 51 and the second clamping head 52 can accurately clamp the jig 80, thereby improving the working accuracy of the clamping assembly 50.

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

[0088] For example Figure 1 As shown, in this embodiment, by setting multiple X-ray emitters 30 and image receivers 40, multiple batteries 90 on the jigs 80 can be tested at the same time, further improving the detection efficiency. Multiple groups of blocking and positioning components 70 are set to make the jigs 80 arranged front and back on the conveyor belt 20 keep a predetermined distance and enter the detection area, so that the detection can be carried out in an orderly manner, avoiding the situation where the battery 90 on a jig 80 is repeatedly tested or the battery 90 is missed.

[0089] Specifically, in this embodiment, multiple groups of clamping components 50 and abutting components 60 can be set to correspond to the X-ray emitter 30; in other words, a clamping component 50 and an abutting component 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 corresponding to the position of each detection interval, so as to clamp multiple fixtures 80 at the same time, move synchronously with the conveyor belt 20, and detect synchronously, thereby improving the detection efficiency.

[0090] like Figure 4As shown, as another implementation of this embodiment, the blocking and positioning assembly 70 is disclosed to include a connecting platform 71, a stopper 72 and a hydraulic transmission rod 73, wherein the connecting platform 71 is connected to the support platform 10 and is arranged on the side of the conveyor belt 20; a fourth guide rail 711 is arranged on the top surface of the connecting platform 71, and the fourth guide rail 711 extends toward the conveyor belt 20; the stopper 72 is slidably arranged on the fourth guide rail 711; the hydraulic transmission rod 73 is arranged on the connecting platform 71 and connected to the stopper 72; the hydraulic transmission rod 73 is used for an external hydraulic press to drive the stopper 72 to move toward or away from the conveyor belt 20; a docking groove 82 is provided on the side of the jig 80, and the stopper 72 is adapted to the docking groove 82.

[0091] Before the detection, the hydraulic transmission rod 73 disclosed in the present embodiment drives the block 72 to move toward the conveyor belt 20. When the jig 80 moves, the block 72 is inserted into the docking groove 82, and the rear end of the docking groove 82 is closed. When the block 72 contacts the rear wall of the docking groove 82, the jig 80 is constrained to stop the movement of the jig 80, so that the clamping assembly 50 and the abutting assembly 60 can stabilize the jig 80. When the jig 80 is abutted, the block 72 moves in the opposite direction and can be disengaged from the docking groove 82. The jig 80 can continue to move with the conveyor belt 20 together with the clamping assembly 50 and the abutting assembly 60 for detection.

[0092] It should be noted that the present embodiment only exemplifies the implementation method of using the hydraulic transmission rod 73 to drive the movement of the block 72, but it is not exhaustive. The block 72 may also be driven by other methods, such as motor drive, as an equivalent replacement of the concept of the present invention and should also be within the scope of protection of this application.
