Description

Technical Field

[0001] This invention belongs to the field of online detection of interface contact quality of solid-state battery cells, specifically relating to an online detection device for interface contact quality of solid-state battery cells. Background Technology

[0002] Cell interface contact quality testing is the inspection of the degree of contact between important parts of the battery, such as cells and electrodes. Ultrasonic penetration imaging is usually used to observe the internal condition of the battery.

[0003] Before ultrasonic testing of batteries, the battery placement needs to be frequently adjusted to ensure optimal testing position. During large-scale testing, manually positioning and fixing each battery consumes a significant amount of time, making it difficult to guarantee testing efficiency. Furthermore, the oxide layer on the battery casing increases the ultrasonic impedance between the battery surface and the testing instrument, making it difficult for ultrasonic waves to penetrate the battery surface and affecting the accuracy of the test results. Typically, a high acoustic impedance coupling agent is applied to the battery surface before testing to ensure effective ultrasonic penetration. However, in actual testing, applying the coupling agent is cumbersome, making it difficult to evenly coat the battery surface. Additionally, the roughness of the battery casing surface can affect the coating of the coupling agent and the penetration of ultrasonic waves. Summary of the Invention

[0004] The purpose of this invention is to provide an online detection device for the interface contact quality of solid-state battery cells, so as to solve the problem of low efficiency in manually positioning batteries when conducting batch testing of a large number of batteries in the prior art.

[0005] To achieve the above objectives, the present invention provides an online detection device for the interface contact quality of solid-state battery cells. This device includes a worktable and an ultrasonic testing instrument. The ultrasonic testing instrument is disposed on the surface of the worktable, which is equipped with a reciprocating screw and a material hopper. A frame is disposed on the surface of the reciprocating screw, which drives the frame to move back and forth to clamp and transport the battery. The ultrasonic testing instrument releases ultrasonic waves to perform ultrasonic testing on the internal battery cells. A fixing groove is rotatably mounted on the surface of the frame, and hooks are rotatably mounted on both sides of the fixing groove, with the hooks and the fixing groove jointly clamping the battery. The battery is held in place. A gear is fitted onto the surface of the hook. Several toothed blocks are arranged on both sides of the worktable. When the frame drives the gear to pass over the toothed blocks, the toothed blocks contact and rub against the surface of the gear, pushing the gear to rotate. The rotation of the gear drives the clamped battery to rotate, allowing the ultrasonic detector to perform penetration testing on the battery from each angle, improving the accuracy of the test results. A protrusion is fixedly installed on the surface of the hook. A first rotating plate is rotatably installed on the surface of the fixing groove near the protrusion. A first baffle is installed between the first rotating plate and the fixing groove. The first baffle limits the first rotating plate, so that the second rotating plate can only rotate unidirectionally to one side, which is used to clamp the hook.

[0006] In one or more embodiments of the present invention, a slide bar is slidably mounted on the surface of the hook, and an arc head is fixedly mounted on the surface of the slide bar. When the hook rotates, it drives the slide bar and the arc head to rotate. The surface of the fixed groove is provided with an arc edge. The surface of the gear is provided with a slot, and the inner wall of the slot is provided with a spiral groove. The slide bar and the protrusion pass through the slot. When the arc head rotates, it pushes the gear to both sides by squeezing the spiral groove, allowing the battery to enter the fixed groove. Before the hook resets, it drives the slide bar and the arc edge to squeeze each other, causing the slide bar to contract and releasing the arc head from limiting the gear. A first spring is provided between the gear and the hook. The gear resets under the elastic force of the first spring and pushes towards the battery, pushing the battery from both sides to center the battery position and enhance the clamping effect on the battery, so that the battery can be detected stably. When the hook is fully reset, the slide bar moves away from the arc edge, and the reset of the slide bar pushes the arc head back into the spiral groove.

[0007] In one or more embodiments of the present invention, a support spring is provided between the fixing groove and the frame, and the distance between adjacent tooth blocks is equal. When the gear is between adjacent tooth blocks, it stops rotating, so that the battery maintains the current angle and then continues to rotate, so that the battery stays at each angle for a period of time, waiting for the ultrasonic detector to complete the detection of the current angle before continuing to rotate, ensuring that the battery can be fully detected at each angle. The end of the hook is rotatably provided and the surface is provided with a rocker plate, and the inside is provided with a first torsion spring. An elastic telescopic rod is installed on the surface of the worktable. The free end and the fixed end of the elastic telescopic rod are bent in a U-shape. The hook is divided into two sections, which are combined to apply pressure to clamp the battery. When the end is lifted, the battery is directly detached.

[0008] In one or more embodiments of the present invention, a material cylinder is fixedly installed on the surface of the workbench, and a discharge port is opened at the bottom of the material cylinder. A limit door is slidably installed at the discharge port. A second spring is provided between the limit door and the material cylinder. The elastic force of the second spring causes the limit door to reset. A second rotating plate is rotatably installed at the bottom of the limit door. A second baffle is installed between the second rotating plate and the limit door. The second baffle limits the second rotating plate, so that the second rotating plate can only rotate in one direction. A protruding rod is fixedly installed on the surface of the frame. The protruding rod pushes the second rotating plate away from the second rotating plate. A second torsion spring is provided between the second rotating plate and the limit door. The elastic force of the second torsion spring causes the second rotating plate to reset.

[0009] In one or more embodiments of the present invention, a scraper is fixedly installed on the surface of the frame. The scraper pushes the coupling agent on the surface of the battery to coat the battery surface evenly with the coupling agent. A pressure plate is slidably installed on the surface of the scraper. A folding rod is installed on the surface of the pressure plate. The folding rod is bent to one side of a gear, and the surface of the gear is provided with several ball heads. A third spring is provided between the pressure plate and the scraper. The pressure plate moves back and forth under the elastic force of the third spring, pushing and spreading the coupling agent around the scraper so that the scraper can evenly coat the coupling agent on the battery surface.

[0010] In one or more embodiments of the present invention, the surface of the material box is provided with an inclined groove, a clamping plate is slidably installed on the surface of the material box, a crank is fixedly installed on the surface of the second rotating plate, a telescopic rod is connected to the surface of the clamping plate, the free end of the telescopic rod is hinged with a crank, and when the crank rotates, it pushes the telescopic rod to move, thereby moving the clamping plate and allowing the battery closest to the clamping plate in the inclined groove to be placed down.

[0011] In one or more embodiments of the present invention, a rotating rod is rotatably mounted on the surface of the material box. The top of the rotating rod is sleeved on the surface of the clamping plate, and a connecting rod is hinged to the bottom. A push plate is slidably mounted on the surface of the worktable. The connecting rod is sleeved on the surface of the push plate. When the clamping plate is reset, it pushes the rotating rod to rotate. After the rotating rod rotates, it drives the push plate to move through the traction connecting rod to push the battery into the clamping area of ​​the frame, so that the frame can clamp the battery. Through the coordinated movement of the clamping plate and the push plate, the material box can quantitatively and orderly put down the battery to be tested, avoiding the batteries from pushing each other and affecting the frame's clamping of the battery.

[0012] In one or more embodiments of the present invention, a grinding plate is slidably installed at the inclined groove, a fourth spring is provided between the grinding plate and the material box, a stop rod is installed on the surface of the clamping plate, and an inclined surface is provided on the surface of the grinding plate near the stop rod. The stop rod moves frequently away from the inclined surface near the surface of the grinding plate, and the grinding plate moves back and forth under the elastic force of the fourth spring to grind the surface of the battery that has not yet fallen off at the inclined groove, so that the surface of the battery after grinding is smoother, which is conducive to the penetration of ultrasonic waves during testing and also facilitates adhesion with the coupling agent.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The automatic clamping and conveying of the battery by the frame eliminates the need for manual fixing of the battery, saving manpower and improving detection efficiency. The gears can push and position the battery from both sides, placing the battery in the optimal detection position. During the detection process, the gears drive the battery to rotate, allowing the battery surface to be fully irradiated by the ultrasonic detector, making the detection results more accurate. The battery stays at various angles for a period of time until the ultrasonic detector is fully aligned and detected before continuing to rotate, ensuring uniform detection of the battery.

[0015] (2) Coupling agent is applied to the battery surface by dripping through the barrel to reduce the resistance between the battery and the ultrasonic tester, making it easier for the ultrasonic waves released by the ultrasonic tester to penetrate the battery surface and accurately test the internal cells. At the same time, the cooperation of the scraper and the pressure plate makes the coupling agent applied to the battery surface evenly and smoothly spread on every corner of the battery surface, so that the battery is in uniform contact with the coupling agent.

[0016] (3) Through the coordinated movement of the clamping plate and the pusher plate, the battery to be tested is placed in the box in a quantitative and orderly manner, avoiding the batteries from pushing each other and affecting the frame's clamping of the battery. In addition, when the pusher plate moves, it drives the grinding plate to move back and forth on the surface of the inclined groove, grinding the battery to be tested that has not yet fallen off the surface of the inclined groove, making the surface of the battery smoother after grinding, which is conducive to the penetration of ultrasonic waves during testing and also facilitates the bonding with the coupling agent.

[0032] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0033] like Figures 1-13 As shown, one embodiment of the present invention is: an online detection device for the interface contact quality of solid-state battery cells, comprising: a workbench 1 and an ultrasonic detector 2. The ultrasonic detector 2 is disposed on the surface of the workbench 1. A reciprocating screw 3 and a material box 6 are disposed on the surface of the workbench 1. A frame 4 is disposed on the surface of the reciprocating screw 3. The reciprocating screw 3 drives the frame 4 to move back and forth to clamp and transport the battery. Ultrasonic waves are released by the ultrasonic detector 2 to perform ultrasonic testing on the internal battery cells. A fixing groove 7 is rotatably installed on the surface of the frame 4. Hooks 8 are rotatably installed on both sides of the fixing groove 7. The hooks 8 and the fixing groove 7 clamp the battery cells together. The battery has a gear 9 sleeved on the surface of the hook 8. Several toothed blocks 5 are set on both sides of the worktable 1. When the frame 4 drives the gear 9 to pass over the toothed blocks 5, the toothed blocks 5 and the surface of the gear 9 come into contact and rub against each other, pushing the gear 9 to rotate. The rotation of the gear 9 drives the clamped battery to rotate. A protrusion 11 is fixedly installed on the surface of the hook 8. A first rotating plate 12 is rotatably installed on the surface of the fixing groove 7 near the protrusion 11. A first baffle 13 is installed between the first rotating plate 12 and the fixing groove 7. The first baffle 13 limits the first rotating plate 12, so that the second rotating plate 21 can only rotate in one direction to clamp the hook 8.

[0034] A slider 10 is slidably mounted on the surface of the hook 8, and an arc head 14 is fixedly mounted on the surface of the slider 10. When the hook 8 rotates, it drives the slider 10 and the arc head 14 to rotate. The surface of the fixed groove 7 is provided with an arc edge 16. The surface of the gear 9 is provided with a slot, and the inner wall of the slot is provided with a spiral groove 15. The slider 10 and the protrusion 11 pass through the slot. When the arc head 14 rotates, it pushes the gear 9 to open to both sides by squeezing the spiral groove 15. A first spring is provided between the gear 9 and the hook 8. The gear 9 returns to its original position under the elastic force of the first spring and pushes towards the battery, pushing the battery from both sides to center the battery position.

[0035] A support spring is provided between the fixed groove 7 and the frame 4. The distance between adjacent tooth blocks 5 is equal. When the gear 9 is between adjacent tooth blocks 5, it stops rotating, so that the battery can maintain the current angle before continuing to rotate. The end of the hook 8 is rotatably provided and the surface is provided with a rocker plate 18. The first torsion spring is provided inside. An elastic telescopic rod 17 is installed on the surface of the worktable 1. The free end of the elastic telescopic rod 17 is bent in a U-shape with the fixed end. The hook 8 is divided into two sections. When they are combined, they apply pressure to clamp the battery. When the end is lifted, the battery is directly detached.

[0036] In this embodiment, the internal condition of the battery cell is detected by the ultrasonic detector 2. The battery is automatically clamped by the frame 4 and rotated during the detection process, so that the ultrasonic detector 2 can perform uniform and sufficient detection of the battery in all directions.

[0037] The reciprocating screw 3 starts, driving the frame 4 to move towards the hopper 6. The battery in the hopper 6 rolls onto the surface of the worktable 1. The movement of the frame 4 moves the fixing groove 7 and the hook 8. When the hook 8 contacts the battery, it is squeezed out of the fixing groove 7. There is no obstruction between the fixing groove 7 and the battery, and the battery enters the fixing groove 7. Simultaneously, the hook 8 rotates one revolution and is about to reset. Before the hook 8 fully resets, the protrusion 11 on the surface of the hook 8 pushes open the first rotating plate 12 and passes over it. The first rotating plate 12, blocked by the first baffle 13 at the bottom, limits the protrusion 11 and the hook 8, causing the hook 8 to firmly hold the battery. When hook 8 rotates, it drives arc head 14 to rotate. After rotating, arc head 14 slides in spiral groove 15. By squeezing spiral groove 15, it pushes gear 9 to open to both sides, allowing the battery to enter fixed groove 7. When hook 8 is about to reset, it will drive slide bar 10 to squeeze against arc edge 16. Under the squeezing of arc edge 16, slide bar 10 retracts into hook 8, driving arc head 14 to move downward away from spiral groove 15, releasing the limit on gear 9. Gear 9 resets under the elastic force of the first spring and pushes against the battery, squeezing the battery from both sides to center the battery position and strengthen the clamping effect on the battery, so that the battery can be tested stably. After the frame 4 completes clamping the battery, the reciprocating screw 3 drives the frame 4 to reset. During the reset process, the gear 9 rubs against the tooth block 5, causing the gear 9 to rotate and drive the battery to rotate, adjusting the battery placement angle and performing all-round ultrasonic testing on the battery. There is a certain distance between the tooth blocks 5. When the gear 9 is between adjacent tooth blocks 5, it stops rotating, keeping the battery at the current angle before continuing to rotate. The battery stays at each angle for a period of time, waiting for the ultrasonic testing instrument 2 to complete the test at the current angle before continuing to rotate, ensuring that the battery can be fully tested at each angle.

[0038] Please see Figures 1-13 Based on the above embodiments, in another embodiment of the present invention, a material cylinder 19 is fixedly installed on the surface of the workbench 1. A discharge port is opened at the bottom of the material cylinder 19. A limit door 20 is slidably installed at the discharge port. A second spring is provided between the limit door 20 and the material cylinder 19. The elastic force of the second spring causes the limit door 20 to reset. A second rotating plate 21 is rotatably installed at the bottom of the limit door 20. A second baffle 23 is installed between the second rotating plate 21 and the limit door 20. The second baffle 23 limits the second rotating plate 21, so that the second rotating plate 21 can only rotate in one direction. A protruding rod 22 is fixedly installed on the surface of the frame 4. The protruding rod 22 pushes the second rotating plate 21 and passes over the second rotating plate 21. A second torsion spring is provided between the second rotating plate 21 and the limit door 20. The elastic force of the second torsion spring causes the second rotating plate 21 to reset.

[0039] A scraper 24 is fixedly installed on the surface of the frame 4. The scraper 24 pushes the coupling agent on the surface of the battery to coat the battery surface evenly with the coupling agent. A pressure plate 25 is slidably installed on the surface of the scraper 24. A bending rod 26 is installed on the surface of the pressure plate 25. The bending rod 26 is bent to the side of one of the gears 9, and the surface of the gear 9 is provided with several ball heads 27. A third spring is provided between the pressure plate 25 and the scraper 24. The pressure plate 25 moves back and forth under the elastic force of the third spring, pushing and spreading the coupling agent around the scraper 24.

[0040] In this embodiment, when the frame 4 clamps the battery and prepares to reset for testing, the frame 4 resets, causing the protruding rod 22 to push the second baffle 23, which in turn causes the limiting door 20 to slide open the outlet. The coupling agent filled in the cylinder 19 drips onto the battery surface, coating the battery surface with a high acoustic impedance coupling agent. This reduces the impedance between the ultrasonic waves released by the ultrasonic detector 2 and the battery surface, improving the ultrasonic penetration and enhancing the testing effect. Furthermore, during battery rotation, the scraper 24 pushes the coupling agent on the battery surface, coating it evenly and ensuring uniform contact. Simultaneously, the rotation of the gear 9 causes the ball head 27 on the surface to rotate. The ball head 27 frequently rubs against one end of the folding rod 26, pushing the folding rod 26 to move and causing the pressure plate 25 to press towards the battery. The pressure plate 25 reciprocates under the force of the third spring, spreading the coupling agent around the scraper 24, allowing the scraper 24 to evenly coat the battery surface with the coupling agent.

[0041] Please see Figures 1-13 Based on the above embodiments, in another embodiment of the present invention, the surface of the material box 6 is provided with a sloping groove 34, the surface of the material box 6 is slidably mounted with a clamping plate 28, the surface of the second rotating plate 21 is fixedly mounted with a crank rod 29, the surface of the clamping plate 28 is connected with a telescopic rod 31, the free end of the telescopic rod 31 is hinged with the crank rod 29, when the crank rod 29 rotates, it pushes the telescopic rod 31 to move, thereby driving the clamping plate 28 to move, so that the battery closest to the clamping plate 28 in the sloping groove 34 is put down.

[0042] A rotating rod 30 is rotatably mounted on the surface of the material box 6. The top of the rotating rod 30 is sleeved on the surface of the clamping plate 28, and the bottom is hinged to a connecting rod 33. A push plate 32 is slidably mounted on the surface of the worktable 1. The connecting rod 33 is sleeved on the surface of the push plate 32. When the clamping plate 28 is reset, it pushes the rotating rod 30 to rotate. After the rotating rod 30 rotates, it drives the push plate 32 to move through the traction connecting rod 33, pushing the battery to the clamping area of ​​the frame 4, so that the frame 4 can clamp the battery.

[0043] A grinding plate 35 is slidably installed at the inclined groove 34. A fourth spring is provided between the grinding plate 35 and the material box 6. A stop rod 36 is installed on the surface of the clamping plate 28. An inclined surface is provided on the surface of the grinding plate 35 near the stop rod 36. The stop rod 36 moves and frequently moves away from the inclined surface near the surface of the grinding plate 35. The grinding plate 35 moves back and forth under the elastic force of the fourth spring to grind the surface of the battery that has not yet fallen off at the inclined groove 34.

[0044] In this embodiment, after each battery test is completed, the frame 4 moves back to the hopper 6 to clamp a new battery for testing. Before this, when the frame 4 moves, it causes the rocker arm 18 to contact the elastic telescopic rod 17. Under the pressure of the elastic telescopic rod 17, the rocker arm 18 causes the end of the hook 8 to flip, directly causing the tested battery to fall off, ready to clamp a new battery to be tested. When the protruding rod 22 pushes the second rotating plate 21 to rotate, the second rotating plate 21 drives the crank rod 29 to rotate. When the crank rod 29 rotates, it pushes the telescopic rod 31 to move, causing the clamping plate 28 to move, so that the battery closest to the clamping plate 28 in the inclined groove 34 is put down, and the battery falls out of the hopper 6. Then, the second rotating plate 21 returns to its original position under the elastic force of the second torsion spring. The clamping plate 28 also resets, blocking the remaining batteries at the inclined groove 34, so that the material box 6 discharges the batteries in a quantitative and orderly manner each time, which facilitates the combination of the batteries and the frame 4. At the same time, when the clamping plate 28 resets, it pushes the rotating rod 30 to rotate. After the rotating rod 30 rotates, it drives the push plate 32 to move through the traction connecting rod 33 to push the batteries to the clamping area of ​​the frame 4, which facilitates the frame 4 to clamp the batteries. Each time the clamping plate 28 moves, it drives the abutment rod 36 to move, frequently moving away from the inclined surface close to the surface of the grinding plate 35. The grinding plate 35 moves back and forth under the elastic force of the fourth spring, grinding the surface of the batteries that have not yet fallen off at the inclined groove 34, making the surface of the batteries smoother after grinding, which is conducive to the penetration of ultrasonic waves during testing and also facilitates the adhesion with the coupling agent.
