Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a battery positioning and testing device. Background Technology

[0002] After the batteries are manufactured, they need to be tested. Since batteries vary in shape and size, specific testing equipment is required for each type of battery.

[0003] Some batteries have protruding tabs on one side of their width. These tabs differ from the battery surface, requiring not only precise image capture of their position but also accurate positioning on the battery to prevent misalignment during testing. Furthermore, the tabs deform after installation, necessitating further fixation to ensure a flat bottom surface during testing, thus improving accuracy. Additionally, battery positioning is crucial during testing to prevent deviations in tab detection due to battery positional issues. Existing battery testing devices fail to meet these requirements; therefore, a suitable battery testing device is needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a battery positioning and detection device.

[0005] To solve the above technical problems, the technical solution of this utility model is as follows:

[0011] As a preferred embodiment of the battery positioning and detection device of this utility model, the second positioning unit includes a mounting base fixedly installed on the detection platform, a first slide rail fixedly installed on the mounting base, a first slide block slidably installed on the first slide rail, and a second driving member for driving the first slide block to slide along the first slide rail, wherein the extension direction of the first slide rail is perpendicular to the length direction of the battery.

[0012] A second slide rail is fixedly installed below the first slide block, and the extension direction of the second slide rail is perpendicular to the extension direction of the first slide rail. A second slide block is slidably installed below the second slide rail, and a positioning base plate is fixedly installed at the bottom of the second slide block. A third driving member is fixedly installed on the positioning base plate. The third driving member is drivenly connected to the second pressure plate and drives the second pressure plate to rise and fall in the vertical direction.

[0013] The mounting base is provided with a guide groove, and a guide wheel is rotatably mounted on the lower end of the positioning base plate. The guide wheel is located in the guide groove, and the width of the guide groove is equal to the outer diameter of the guide wheel.

[0014] When the guide wheel is located at the first end of the guide groove, and the third driving member drives the second pressure plate to move to a predetermined position, the end of the second pressure plate presses against the top of the electrode tab, and the electrode tab is perpendicular to the detection direction of the detection component.

[0015] As a preferred embodiment of the battery positioning and detection device of this utility model, the guide groove is S-shaped and includes a first groove, a second groove, and a transition groove connecting the first groove and the second groove. The length directions of the first groove and the second groove are both extended along the extension direction of the first slide rail.

[0016] As a preferred embodiment of the battery positioning and detection device of this utility model, a battery limiting plate is fixedly provided on the detection platform. The battery limiting plate is L-shaped and includes a first limiting plate and a second limiting plate that are perpendicular to each other.

[0017] When the battery to be tested is placed on the testing platform, the end of the battery to be tested away from the tab is attached to the inner side of the first limiting plate, and the side of the battery to be tested in the width direction is attached to the inner side of the second limiting plate.

[0018] In a preferred embodiment of the battery positioning and detection device of this utility model, the detection platform is provided with a plurality of adsorption components for adsorbing the battery to be tested. When the side of the battery to be tested is in contact with the battery limiting plate, the adsorption components are located below the battery to be tested, and the plurality of adsorption components are evenly distributed in the middle of the battery to be tested.

[0019] In a preferred embodiment of the battery positioning and detection device of this utility model, a first through hole is provided on the detection platform below the electrode tab, the length of the first through hole is greater than the length of the electrode tab, and the width of the first through hole is greater than the width of the electrode tab.

[0022] When the side of the battery to be tested is in contact with the battery limiting plate, and the first pressure plate presses the tab tightly against the side of the battery, the second through hole is located directly below the tab, and the axis of the tab coincides with the axis of the second through hole.

[0023] The beneficial effects of this utility model are:

[0024] (1) The present invention is provided with a tab positioning component. The first positioning unit presses the tab tightly to the side of the battery to ensure the stability of the tab position during the detection process, thereby improving the detection accuracy of the tab. At the same time, the second positioning unit presses the tab down to make the tab perpendicular to the detection direction of the detection component, ensuring the flatness of the bottom of the tab during the detection process.

[0025] (2) The present invention has a fixed platform on the detection platform. The battery limit plate is used to position the two adjacent sides of the battery to be tested, thereby realizing the pre-positioning of the battery. Then, the battery is adsorbed by the adsorption component to ensure that the battery will not shift when the tab is tested. This ensures the positional stability of the battery during the testing process and avoids the battery position shifting due to mechanical equipment or external vibration interference, thereby further improving the detection accuracy.

[0026] (3) The present invention has a guide wheel rotatably installed at the bottom of the positioning base plate and a corresponding guide groove is opened on the mounting seat. Through the cooperation of the guide wheel and the guide groove, the first slide block can slide along the first slide rail to drive the second pressure plate to move in an S-shape to the top of the electrode ear. Then, the second pressure plate is driven to move downward by the third driving component, so that the second pressure plate can press down on the electrode ear. This effectively reduces the number of driving components and lowers the cost. Attached Figure Description

Detailed Implementation

[0037] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0038] Figure 1 This is a schematic diagram of the battery positioning and detection device provided in an embodiment of this application. The device includes a detection platform 100, a detection component 200, and a tab positioning component 300. The battery 400 to be tested is placed on the detection platform 100, the tab positioning component 300 positions the tabs 410 of the battery 400, and then the detection component 200 performs image detection on the tabs 410 to ensure the detection accuracy of the tabs 410.

[0039] For details, see Figures 1-8 The upper surface of the testing platform 100 is rectangular and parallel to the horizontal plane. A fixing platform for placing and securing the battery 400 to be tested is provided on one side of the testing platform 100. A tab 410 positioning assembly 300 is provided on the other side of the testing platform 100. A detection assembly 200 is fixedly installed at the bottom of the testing platform 100, with the detection direction vertically upward, and can perform supplementary lighting imaging on the battery 400 tabs 410 on the fixing platform.

[0040] A battery limiting plate 110 is fixedly installed on a fixed platform. The battery limiting plate 110 has an L-shaped cross-section and includes a first limiting plate 111 and a second limiting plate 112 that are perpendicular to each other. The first limiting plate 111 is parallel to the length direction of the detection platform 100, and the second limiting plate 112 is parallel to the width direction of the detection platform 100. The first limiting plate 111 and the second limiting plate 112 can respectively limit the two adjacent sides of the battery 400 to be tested, ensuring the positional stability of the battery 400 during the testing process.

[0041] It should be noted that the battery 400 to be tested is gripped by a mechanical gripper and placed on a fixed platform. During the gripping process, the mechanical gripper passes by a positioning camera. The positioning camera captures and positions the battery 400 on the mechanical gripper, and the system calculates to ensure that the mechanical gripper accurately places the battery 400 on the fixed platform, with the two adjacent sides of the battery 400 respectively abutting against the inner sides of the first limiting plate 111 and the second limiting plate 112, thus securing the battery 400.

[0042] Furthermore, several adsorption components 130 are provided on the fixed platform. Each adsorption component 130 includes an adsorption hole formed on the fixed platform and an adsorption head disposed within the adsorption hole. After the mechanical gripper places the battery 400 on the fixed platform, these adsorption components 130 are all located below the battery 400 to be tested, and several adsorption components 130 are evenly distributed in the middle of the battery 400 to be tested. By adsorbing the battery 400 through these adsorption components 130, the battery 400 to be tested is fixed on the fixed platform, further ensuring the positional stability of the battery 400 during the testing process, avoiding displacement of the battery 400 due to mechanical equipment or external vibration interference, thereby improving the testing accuracy.

[0043] It is understandable that the adsorption component 130 can also be arranged in other ways, such as being evenly distributed around the battery to be tested.

[0044] The tab positioning assembly 300 is used to position the tabs 410 of the battery 400 placed on a fixed platform. It should be noted that during the testing of the tabs 410 of the battery 400, the tabs 410 are not completely fixed to the battery 400, but are connected to the battery 400 via connecting tabs. Therefore, the tabs 410 need to be positioned during the testing process. Simultaneously, because the tabs 410 are not completely fixed, they will tilt upwards at a certain angle relative to the surface of the battery 400. Therefore, the tab 410 positioning assembly 300 includes a first positioning unit for pressing the tabs 410 against the side of the battery 400 and a second positioning unit for pressing onto the top of the tabs 410 and positioning the tabs 410 perpendicular to the testing direction of the testing assembly 200.

[0045] Specifically, the first positioning unit includes a first driving member 301 fixedly mounted on the detection platform 100 and a first pressure plate 302 drivenly connected to the first driving member 301. The first driving member 301 is located on one side of the fixed platform. The length direction of the first pressure plate 302 is parallel to the length direction of the detection platform 100 and is located on the side of the tab 410 away from the battery 400. The driving direction of the first driving member 301 is parallel to the length direction of the battery 400, that is, when the first driving member 301 is running, it will drive the first pressure plate 302 to move along the length direction of the battery 400.

[0046] It should be noted that the end of the first pressure plate 302 is flush with the tab 410 in the width direction of the detection platform 100, and the height of the first pressure plate 302 is lower than the height of the tab 410 body. Under the drive of the first driving member 301, the end of the first pressure plate 302 can press against the connecting piece below the tab 410, and press the connecting piece tightly against the side of the battery 400, thereby fixing the tab 410 on the battery 400 and ensuring that the position of the tab 410 will not shift during the detection process.

[0047] The second positioning unit includes a mounting base 303 fixedly mounted on the detection platform 100, located on the side of the first driving member 301 away from the fixed platform. Two first slide rails 304 are fixedly mounted on the mounting base 303. These two first slide rails 304 are arranged sequentially along the width direction of the detection platform 100, and both first slide rails 304 are perpendicular to the length direction of the battery 400, extending along the length direction of the detection platform 100. An L-shaped first slide block 305 is slidably mounted on the two first slide rails 304, sliding along the first slide rails 304 under the drive of the second driving member 306. A second slide rail 307 is fixedly mounted at the lower end of the first slide block 305, extending perpendicular to the extension direction of the first slide rail 304, extending along the width direction of the detection platform 100. A second slide block 308 is slidably mounted below the second slide rail 307, and a positioning base plate 309 is fixedly mounted at the bottom of the second slide block 308. A third driving component 310 is fixedly mounted on the positioning base plate 309 via a connecting plate, and the third driving component 310 is drivenly connected to the second pressure plate 311. The second pressure plate 311 moves up and down vertically under the drive of the third driving component 310. A connecting rod extending vertically is fixedly mounted on the bottom of the positioning base plate 309, and a guide wheel 313 is rotatably mounted on the lower end of the connecting rod. The axis of the guide wheel 313 coincides with the axis of the connecting rod. At the same time, a guide groove 312 is formed on the mounting base 303 corresponding to the position of the guide wheel 313. The guide wheel 313 is located in the guide groove 312, and the diameter of the guide wheel 313 is equal to or slightly smaller than the width of the guide groove 312.

[0048] The guide groove 312 is generally S-shaped and includes a first groove 314, a second groove 315, and a transition groove 316 connecting the first groove 314 and the second groove 315. The length directions of both the first groove 314 and the second groove 315 extend along the length direction of the detection platform 100, that is, along the extension direction of the first slide rail 304. Along the length direction of the detection platform 100, the distance between the first groove 314 and the tab 410 is greater than the distance between the second groove 315 and the tab 410. Along the width direction of the detection platform 100, the distance between the first groove 314 and the center of the battery 400 is greater than the distance between the second groove 315 and the center of the battery 400.

[0049] Initially, the guide wheel 313 is located at the end of the first groove 314 away from the second groove 315. At this time, there is a certain distance between the end of the second pressure plate 311 and the electrode tab 410 along both the length and width directions of the detection platform 100. During the process of the second driving member 306 driving the first slide block 305 to slide along the first slide rail 304, it can be subdivided into three stages. The first stage is the movement of the guide wheel 313 along the first groove 314. The second stage is the movement of the guide wheel 313 from the first groove 314 into the transition groove 316 and along the transition groove 316. The third stage is the movement of the guide wheel 313 from the transition groove 316 into the second groove 315 and along the second groove 315. Taking the length direction of the detection platform 100 as the X-axis and the width direction as the Y-axis, the end of the second pressure plate 311 and the electrode tab 410 are both considered as a single point. In the first stage, the second pressure plate 311 moves only along the length of the detection platform 100. The difference between the abscissa of the end of the second pressure plate 311 and the tab 410 gradually decreases, while the difference in ordinate remains unchanged. In the second stage, the second pressure plate 311 moves simultaneously along both the length and width of the detection platform 100. The difference between the abscissa and ordinate of the end of the second pressure plate 311 and the tab 410 gradually decreases, and at the end of the second stage, the difference in ordinate between the end of the second pressure plate 311 and the tab 410 is 0. In the third stage, the second pressure plate 311 moves only along the length of the detection platform 100. The difference between the abscissa of the end of the second pressure plate 311 and the tab 410 gradually decreases, and at the end of the third stage, the difference between the abscissa and ordinate of the end of the second pressure plate 311 and the tab 410 is 0. At this point, the end of the second pressure plate 311 is directly above the tab 410. The second pressure plate 311 is driven downward by the third driving member 310, so that the end of the second pressure plate 311 is pressed onto the tab 410 and the tab 410 is parallel to the horizontal plane. At this time, the tab 410 is perpendicular to the detection direction of the detection assembly 200, thereby ensuring the flatness of the bottom surface of the tab 410 during the detection process.

[0050] In this embodiment, the first driving member 301, the second driving member 306, and the third driving member 310 can all be any one of electric cylinder, pneumatic cylinder, or hydraulic cylinder.

[0051] Preferably, a first through hole 120 is provided on the testing platform 100 below the tab 410. The length of the first through hole 120 is greater than the length of the tab 410, and the width of the first through hole 120 is greater than the width of the tab 410. When the side of the battery 400 to be tested is in contact with the battery limiting plate 110, the axis of the tab 410 coincides with the axis of the first through hole 120. The testing component 200 can perform imaging testing on the bottom of the tab 410 through the first through hole 120.

[0052] Furthermore, a second through hole is provided at the end of the first pressure plate 302. The length of the second through hole is greater than the length of the tab 410, and the width of the second through hole is greater than the width of the tab 410. When the side of the battery 400 to be tested is in contact with the battery limiting plate 110, and the first pressure plate 302 presses the tab 410 tightly against the side of the battery 400, the second through hole is located directly below the tab 410, and the axis of the tab 410 coincides with the axis of the first through hole 120. In this way, the first pressure plate 302 will not obstruct the tab 410, allowing the detection component 200 to capture a complete image of the bottom of the tab 410.

[0053] In operation, the aforementioned battery positioning and testing device first uses mechanical grippers to place the battery to be tested onto the testing platform, which is then secured by a fixed platform. Next, the first positioning unit in the tab positioning assembly presses the tab firmly against the side of the battery, ensuring the stability of the tab's position during testing. Then, the second positioning unit in the tab positioning assembly presses the tab downwards, making it perpendicular to the testing direction of the testing assembly. Finally, the testing assembly takes a photograph of the bottom of the tab for inspection.

[0054] Therefore, the technical solution of this application uses the electrode positioning component 300 to position the electrode 410 and its angle, which not only ensures the flatness of the bottom of the electrode 410 during the detection process, but also ensures the stability of the position of the electrode 410 during the detection process, thereby improving the detection accuracy of the electrode 410.

[0055] In addition to the above embodiments, the present invention may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
