Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and more specifically to a battery cap testing device. Background Technology

[0002] The lithium battery cap is a component of a lithium battery, serving as a positive conductive terminal, a safety valve, and a battery seal. The lithium battery cap includes a top cover, a rubber ring, an explosion-proof diaphragm, an aluminum / nickel sheet, and a perforated plate. The top cover is mounted on top of the rubber ring. The perforated plate is mounted on bottom of the rubber ring. The aluminum / nickel sheet is mounted in the middle of the rubber ring, between the top cover and the perforated plate. An explosion-proof diaphragm is located between the aluminum / nickel sheet and the perforated plate. The bottom surface of the perforated plate has a welding point recess. During installation, the explosion-proof diaphragm and the perforated plate are welded together at the welding point recess using laser spot welding, leaving a laser weld point at the weld point recess. The laser weld point and the welding point recess have a tight bond.

[0003] During the manufacturing process, due to various factors such as falling off during vibratory handling, damage to appearance, and poor quality, some battery caps may have defects such as pore damage. If these caps with pore defects are installed on the battery, it will cause the battery to fail to properly seal the electrolyte, resulting in risks such as leakage and impurities entering the battery, which will affect the battery quality. Therefore, testing devices are used to inspect them. Chinese patent CN202020447776.9 discloses a tooling for inspecting the inner hole of a new energy battery cap. The tooling includes a first connecting block with a sliding groove inside. The cap can be stored through an inlet hole and placed into a feeding hole. A telescopic cylinder and a pusher block move the feeding block towards a glass plate via a sliding connection with the sliding groove, positioning the feeding hole with the cap between the lenses of two camera components. After the camera components finish shooting, the telescopic cylinder moves the feeding hole outside the glass plate, causing the cap inside to fall out. The telescopic cylinder then repositions the feeding block. Once the feeding block is reset, the next cap falls into the feeding hole, and the telescopic cylinder repositions the feeding block for the next inspection. The device has a simple overall structure, is easy to operate, and is highly practical.

[0004] However, the aforementioned patent cannot automatically unload and store defective battery caps separately, thus failing to effectively differentiate between defective and good products. Although other existing detection devices can blow out defective products by blowing air, this method is not convenient for collecting defective products. Summary of the Invention

[0005] The purpose of this invention is to provide a battery cap detection device in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A battery cap detection device includes a detection component and a material box, and also includes a conveying component, a pusher plate and a pushing component;

[0008] The detection assembly includes a support, a groove is provided on the front of the support, a first detection head and a second detection head are respectively provided at the top and bottom of the groove, and a first transparent plate is provided between the first detection head and the second detection head;

[0009] The material storage box is located on the right side of the detection component and its side is attached to the detection component. The material storage box includes a box body, which is divided into a waste trough and a storage trough by a partition plate. The waste trough is located on the side closer to the detection component. A waste discharge port is opened at the top of the waste trough. A cylinder is installed at the bottom of the waste trough. A closed plate connected to the inner wall of the waste trough is installed above the cylinder. A push rod is connected to the top of the cylinder. One end of the push rod passes through the closed plate and is connected to a plug that matches the waste discharge port. A nozzle is connected to the inner wall of the waste trough near the top. The nozzle is connected to an external air jet device. The top of the storage trough is open.

[0010] The conveying assembly is mounted on the support frame. The conveying assembly is located to the left of the detection assembly and its side is in contact with the detection assembly. The conveying assembly includes a conveyor belt.

[0011] The push plate is located on the top surface of the conveyor belt, and the bottom surface of the push plate is in contact with the top surface of the conveyor belt. The first transparent plate is flush with the top surface of the conveyor belt and the material box. The push plate has a detection slot in the vertical direction. The top of the detection slot is provided with a second transparent plate. The two sides of the second transparent plate are connected to the push plate. The end of the push plate away from the material box is connected to the pushing component. The pushing component is used to push or pull the push plate in the horizontal direction.

[0012] Furthermore, the number of detection channels is multiple and they are evenly distributed along the long axis of the push plate.

[0013] Furthermore, a material loading bin is also provided between the conveying component and the pushing component.

[0014] Furthermore, the pushing component includes a support platform, and the top of the support platform has an installation groove along the setting direction. Two driving components are arranged inside the installation groove, and the two driving components are symmetrically arranged on the inner wall of the support platform.

[0015] The drive assembly includes a first connecting plate, a second connecting plate, a third connecting plate, a drive plate, and a drive protrusion. One end of the first connecting plate is rotatably connected to the inner wall of the support platform. A drive motor is provided on the outer wall of the support platform. The output shaft of the drive motor passes through the support platform and is connected to the connection end between the first connecting plate and the support platform. The other end of the first connecting plate, facing away from the drive motor, is rotatably connected to one end of the second connecting plate. The other end of the second connecting plate is rotatably connected to one end of the third connecting plate. The other end of the third connecting plate is rotatably connected to the inner wall of the support platform. The third connecting plate is located diagonally above the first connecting plate.

[0016] The bottom of the drive plate is provided with two bottom protrusions, which are rotatably connected to the middle protrusions of the two second connecting plates respectively. The top of the drive plate is provided with multiple drive protrusions, and the push plate is provided with multiple through holes that match the drive protrusions.

[0017] Furthermore, the first connecting plate, the second connecting plate, the third connecting plate, and the bottom flange are all connected by a hinged connection.

[0018] Furthermore, the distance between each side of the through hole and each side of the drive protrusion is 2–5 mm.

[0019] Furthermore, the top surface of the support platform has recesses on both sides of the mounting groove along the long axis, and the two recesses form a limiting slide groove with the top of the mounting groove, which matches the push plate.

[0020] Furthermore, the two side walls and bottom surface of the limiting slide are in contact with the two side walls and bottom surface of the push plate, respectively.

[0021] Furthermore, the plug and the push rod are connected in a detachable manner.

[0022] Furthermore, both the first and second transparent panels are made of glass.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention utilizes the cooperation of a detection component, a material storage box, a conveying component, a pusher plate, and a pushing component. Under the pushing action of the pushing component, the pusher plate is pushed towards the detection component. When the detection channel moves below the detection head, the detection component detects the battery caps in the detection channel to determine whether they meet the standards. If the battery cap is defective, the cylinder is activated, the push rod drives the block downward, and the pushing component pushes the pusher plate forward. When the detection channel moves to the waste discharge port, the discarded battery cap falls from the waste discharge port into the waste trough. If the battery cap is not defective, the cylinder is not activated, and the pushing component continues to push the pusher plate forward. When the detection channel is above the storage trough, the battery cap falls from the opening into the storage trough. This invention can collect defective battery caps into the waste trough in advance, automatically unloading and storing defective battery caps separately.

[0025] 2. This invention, by setting up two material boxes, with the two material boxes located on the left and right sides of the detection component respectively, allows the pusher plate to be pulled back directly by the pusher component after the last battery cap under the pusher plate has been detected, without having to push the pusher plate forward again. During the process of pulling the first detection channel back onto the conveyor belt, the last battery cap will pass through the material box on the left and fall into the waste trough or storage trough of the material box. This can save working steps and time, and improve detection efficiency.

[0026] 3. In this invention, two drive components, a support platform and a mounting slot, work together. A drive motor drives the first connecting plate to rotate, and the first connecting plate drives the second and third connecting plates to move. This causes the drive plate to move up and down reciprocatingly, and pushes the push plate forward during the reciprocating motion. Conversely, when the drive motor rotates in the opposite direction, the drive protrusion on the drive plate will pull the push plate back. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0035] Example 1

[0036] like Figure 1 As shown, this embodiment provides a battery cap detection device, including a detection component 1 and a material box, as well as a conveying component 20, a pusher plate 23 and a pushing component 25;

[0037] The detection component 1 includes a support 2, a groove 4 is provided on the front side of the support 2, a first detection head 3 and a second detection head 19 are respectively provided at the top and bottom of the groove 4, and a first transparent plate 9 is provided between the first detection head 3 and the second detection head 19.

[0038] The material storage box is located on the right side of the detection component 1 and its side is in contact with the detection component 1. The material storage box includes a box body 14. The box body 14 is divided into a waste trough 8 and a storage trough 13 by a partition plate 16. The waste trough 8 is located on the side close to the detection component 1. A waste discharge port 6 is opened at the top of the waste trough 8. A cylinder 18 is installed at the bottom of the waste trough 8. A sealing plate 15 connected to the inner wall of the waste trough 8 is installed above the cylinder 18. A push rod 17 is connected to the top of the cylinder 18. One end of the push rod 17 passes through the sealing plate 15 and is connected to a block 7 that matches the waste discharge port 6. A nozzle 5 is connected to the inner wall of the waste trough 8 near the top. The nozzle 5 is connected to an external jetting device. The top of the storage trough 13 is open.

[0039] The conveying assembly 20 is mounted on the support frame 22. The conveying assembly 20 is located on the left side of the detection assembly 1 and its side is in contact with the detection assembly 1. The conveying assembly 20 includes a conveyor belt 21.

[0040] The push plate 23 is located on the top surface of the conveyor belt 21, and the bottom surface of the push plate 23 is in contact with the top surface of the conveyor belt 21. The first transparent plate 9 is flush with the top surface of the conveyor belt 21 and the material box. The push plate 23 has a detection groove 12 in the vertical direction. The top of the detection groove 12 is provided with a second transparent plate 11. The two sides of the second transparent plate 11 are connected to the push plate 23. The end of the push plate 23 away from the material box is connected to the pushing component 25. The pushing component 25 is used to push or pull the push plate 23 in the horizontal direction.

[0041] This invention utilizes the cooperation of a detection component 1, a material box, a conveying component 20, a pusher plate 23, and a pushing component 25. Under the pushing action of the pushing component 25, the pusher plate 23 is pushed towards the detection component 1. When the detection channel 12 moves below the detection head, the detection component 1 detects the battery cap in the detection channel 12 to determine whether it meets the standard. If the battery cap is defective, the cylinder 18 is activated, the push rod 17 drives the block 7 downward, and the pushing component 25 pushes the pusher plate 23 to continue moving downward. Moving forward, when the detection channel 12 moves to the waste discharge port 6, the discarded battery cap falls from the waste discharge port 6 into the waste trough 8. If the battery cap is not defective, the cylinder 18 does not start. When the pushing component 25 continues to push the push plate 23 forward, and the detection channel 12 is above the storage trough 13, the battery cap falls from the opening into the storage trough 13. The present invention can collect defective battery caps into the waste trough 8 in advance, and automatically unload and store defective battery caps separately.

[0042] Example 2

[0043] This embodiment is based on Embodiment 1, and further optimizes the detection efficiency.

[0044] like Figure 1 As shown, there are multiple detection slots 12, which are evenly distributed along the long axis of the push plate 23.

[0045] Furthermore, a material storage box is provided between the conveying component 20 and the pushing component 25.

[0046] This invention, by setting up two material boxes, with the two material boxes located on the left and right sides of the detection component 1 respectively, allows the pusher plate 23 to be pulled back directly by the pusher component 25 after the last battery cap under the pusher plate 23 has been detected, without having to push the pusher plate 23 forward again. During the process of pulling the first detection channel 12 back onto the conveyor belt 21, the last battery cap will pass through the material box on the left and fall into the waste trough 8 or storage trough 13 of the material box. This can save working steps and time, and improve detection efficiency.

[0047] Example 3

[0048] This embodiment describes the structure of the push component 25 based on the above embodiment.

[0049] like Figure 2 , Figure 4 and Figure 5 As shown, the push component 25 includes a support platform 10. The top of the support platform 10 is provided with an installation groove 26 along the setting direction. Two drive components 31 are arranged inside the installation groove 26. The two drive components 31 are symmetrically arranged on the inner wall of the support platform 10.

[0050] The drive assembly 31 includes a first connecting plate 28, a second connecting plate 29, a third connecting plate 32, a drive plate 33, and a drive protrusion 30. One end of the first connecting plate 28 is rotatably connected to the inner wall of the support platform 10. A drive motor is provided on the outer wall of the support platform 10. The output shaft of the drive motor passes through the support platform 10 and is connected to the connection end of the first connecting plate 28 and the support platform 10. The other end of the first connecting plate 28, facing away from the drive motor, is rotatably connected to one end of the second connecting plate 29. The other end of the second connecting plate 29 is rotatably connected to one end of the third connecting plate 32. The other end of the third connecting plate 32 is rotatably connected to the inner wall of the support platform 10. The third connecting plate 32 is located diagonally above the first connecting plate 28.

[0051] The bottom of the drive plate 33 is provided with two bottom protrusions 34, which are rotatably connected to the middle protrusions 35 of the two second connecting plates 29 respectively. The top of the drive plate 33 is provided with multiple drive protrusions 30, and the push plate 23 is provided with multiple through holes 24 that match the drive protrusions 30.

[0052] As an feasible approach, the first connecting plate 28, the second connecting plate 29, the third connecting plate 32 and the bottom flange 34 are all connected by a hinged connection.

[0053] As a preferred embodiment, the distance between each side of the through hole 24 and each side of the drive protrusion 30 is 2 to 5 mm.

[0054] The present invention utilizes the cooperation of two drive components 31 of the support platform 10 and the mounting groove 26. The drive motor drives the first connecting plate 28 to rotate, and the first connecting plate 28 drives the second connecting plate 29 and the third connecting plate 32 to move, thereby causing the drive plate 33 to move up and down reciprocatingly. During the reciprocating motion, the drive plate 23 is pushed forward. Conversely, when the drive motor rotates in the opposite direction, the drive protrusion 30 on the drive plate 33 will pull the push plate 23 back.

[0055] Example 4

[0056] This embodiment is based on the above embodiment and explains the stability handling of the push plate 23 movement.

[0057] like Figure 3As shown, the top surface of the support platform 10 is provided with recesses 27 on both sides of the mounting groove 26 along the long axis. The two recesses 27 and the top of the mounting groove 26 form a limiting slide groove, which matches the push plate 23.

[0058] In a preferred manner, the two side walls and the bottom surface of the limiting groove are in contact with the two side walls and the bottom surface of the push plate 23, respectively.

[0059] Example 5

[0060] This embodiment is a further optimization of the present invention based on the above embodiments.

[0061] like Figure 1 As shown, preferably, the block 7 and the push rod 17 are connected in a detachable manner.

[0062] Preferably, both the first transparent plate 9 and the second transparent plate 11 are made of glass.

[0063] The working principle of this invention is as follows: The transmission frequency of the conveyor belt 21 of the conveyor assembly 20 is coordinated with the movement of the push plate 23. After the conveyor belt 21 transmits a battery cap to the corresponding detection slot 12, the drive motor is started. The drive motor drives the first connecting plate 28 to rotate. The first connecting plate 28 drives the second connecting plate 29 and the third connecting plate 32 to move, thereby causing the drive plate 33 to move up and down reciprocatingly. During the reciprocating motion, the push plate 23 is pushed forward, and the detection slot 12 is pushed onto the detection assembly 1. At this time, the next detection slot 12 is located on the conveyor belt 21. The conveyor belt 21 transmits again, transmitting the next battery cap to be tested to this detection slot 12. The detection assembly 1 tests the battery cap to determine whether it is qualified. If it is qualified... When the pusher assembly 25 pushes the pusher plate 23 forward, the battery cap falls into the waste trough when the detection channel 12 is above the discharge channel. If the battery cap is not qualified, the cylinder 18 will be activated and the pusher rod 17 will move downward. The pusher rod 17 will simultaneously move the block 7 downward. The block 7 will disengage from the waste discharge port 6. When the pusher assembly 25 pushes the pusher plate 23 forward, the unqualified battery cap will fall into the waste trough 8 from the waste discharge port 6. In order to prevent the battery cap from falling on the top of the block 7 and being pushed out again by the block 7, the gas is sprayed into the nozzle 5 through the jet device, so as to spray the battery cap off the block 7 and drop it into the waste trough 8. The next battery cap is now on the detection assembly 1. After the detection is completed, the pusher assembly 25 pushes the pusher plate 23 again to discharge the battery.

[0064] It should be noted that the transmission component 20 is an existing device with transmission function, which can be connected to the existing vibratory feeder to directly output the battery caps in an orderly manner. It is only necessary to control its opening and closing frequency, which will not be elaborated here.
