[0002] To reduce the risk of mechanical impact, some batteries, especially lithium-ion batteries, require cushioning pads (such as foam pads) on their outer surface. Lithium-ion batteries are widely used in various electronic devices due to their high energy density, small size, light weight, and adaptability.

[0003] Currently, the process of attaching buffer pads to the outer surface of lithium-ion batteries is done manually, and the inspection for missing buffer pads is also done manually by visually inspecting the appearance of the lithium-ion batteries. Therefore, the existing buffer pad missing inspection process carries the risk of lithium-ion batteries with missing buffer pads being shipped out, resulting in high customer complaint rates and high rework costs. Utility Model Content

[0004] This utility model provides a battery buffer pad missing detection device to solve the problem that existing battery buffer pad missing inspection processes have the risk of lithium-ion batteries with missing buffer pads leaking out, resulting in high customer complaint rates and high rework costs.

The movable plate covers the opening; A first stop is provided on the inclined surface and near the downstream side of the opening. A first screening gap is formed between the first stop and the inclined surface. The height of the first screening gap is greater than the thickness of the battery with the missing buffer pad and less than the thickness of the qualified battery. A drive mechanism, connected to the movable plate, is used to drive the movable plate to open the opening to allow qualified batteries to fall in, and to drive the movable plate to reset and close the opening to receive batteries that slide freely down the inclined surface.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] This utility model embodiment provides a battery buffer pad missing adhesion detection device, such as Figure 1 As shown, the battery buffer pad missing detection device includes a base 10, a movable plate 20, a first stop 30, and a drive mechanism 40.

[0020] The base 10 is provided with an inclined surface 10a for the battery to slide freely, and an opening 10b for the battery to fall into the inclined surface 10a.

[0021] The movable plate 20 covers the opening 10b. Preferably, the movable plate 20 can be movably accommodated in the opening 10b. More preferably, one side surface of the movable plate 20 is coplanar with the inclined surface 10a, facilitating the free sliding of the battery.

[0022] The first stop 30 is located on the inclined surface 10a and is close to the downstream side of the opening 10b. A first screening gap 30a is formed between the first stop 30 and the inclined surface 10a. The height of the first screening gap 30a is greater than the thickness of the battery with the missing buffer pad and less than the thickness of the qualified battery.

[0023] The drive mechanism 40 is connected to the movable plate 20 and is used to drive the movable plate 20 to open the opening 10b to allow a qualified battery to fall in, and to drive the movable plate 20 to reset and close the cover at the opening 10b to receive a battery that slides freely down the inclined surface 10a. Specifically, the drive mechanism 40 is connected to the movable plate 20 and is used to drive the movable plate 20 away from the opening 10b to open the opening 10b, or to drive the movable plate 20 to rotate to open the opening 10b.

[0024] The battery buffer pad missing detection device of this application embodiment provides an inclined surface 10a on the base 10 for batteries to slide freely. A first screening gap 30a is formed between the first stop 30 on the inclined surface 10a and the inclined surface 10a. Batteries missing buffer pads can pass through the first screening gap 30a, thereby sorting out the batteries missing buffer pads. Qualified batteries with buffer pads are blocked by the first stop 30 and stay on the movable plate 20. The driving mechanism 40 can drive the movable plate 20 to open the opening 10b, allowing the qualified batteries on the movable plate 20 to fall from the opening 10b, thereby screening out qualified batteries, reducing the risk of batteries missing buffer pads flowing out, reducing customer complaints, and reducing rework costs.

[0025] refer to Figure 1 and Figure 2 In an optional embodiment of this application, the drive mechanism 40 includes a drive cylinder 41 and a connecting plate 42. The drive cylinder 41 is mounted on the base 10, and the drive end of the drive cylinder 41 is connected to the connecting plate 42. The movable plate 20 is fixed on the connecting plate 42. The drive cylinder 41 drives the connecting plate 42 to rotate, so as to drive the movable plate 20 to rotate to open the port 10b or reset the cover to close the port 10b.

[0026] The drive cylinder 41 serves as the power source, and its output force is transmitted to the movable plate 20 through the connecting plate 42. This causes the movable plate 20 to rotate and open the opening 10b, allowing a qualified battery blocked by the first stop 30 to fall smoothly from the opening 10b. Alternatively, it causes the movable plate 20 to reset and close itself to the opening 10b, accommodating the next battery and allowing it to slide freely down the inclined surface 10a to the first stop 30. The connecting plate 42 solves the connection and compatibility problem between the drive end of the drive cylinder 41 and the movable plate 20 (such as size mismatch or limited installation position). The connecting plate 42 can be designed according to the spatial relationship between the two to ensure efficient power transmission. The drive cylinder 41 has a fast response speed, stable output force, and controllable stroke, reducing misoperation. In other embodiments, a motor can also be used as the power source to drive the connecting plate 42 to rotate, thereby causing the movable plate 20 to move away from the opening 10b on the inclined surface 10a or reset and close itself to the opening 10b. Alternatively, a cylinder or motor can be used as a power source to drive the connecting plate 42 to move horizontally, thereby driving the movable plate 20 to move away from or reset the cover to fit the opening 10b.

[0027] refer to Figure 1 In an optional embodiment of this application, the battery buffer pad missing detection device further includes a detection mechanism 50. The detection mechanism 50 is used to detect whether a qualified battery is carried on the movable plate 20, and outputs a sensing signal after detecting that a qualified battery is carried on the movable plate 20. The driving mechanism 40 drives the movable plate 20 to open the port 10b based on the sensing signal.

[0028] Specifically, when there is a qualified battery on the movable plate 20, the detection mechanism 50 can detect it and output a sensing signal. Based on the sensing signal, the drive mechanism 40 starts to open the movable plate 20, allowing the qualified battery to fall from the opening 10b. After completion, the drive mechanism 40 can drive the movable plate 20 to reset and close to the opening 10b, allowing the next battery to be inspected to slide along the inclined surface 10a through the movable plate 20 to the first stop 30. Therefore, by setting the detection mechanism 50, it is possible to detect whether the movable plate 20 carries a qualified battery, provide an action trigger signal for the drive mechanism 40, realize the automatic flow of qualified batteries, improve the automation level of the battery buffer pad missing detection device, and improve the battery inspection efficiency.

[0029] Optional, see reference Figure 1 The detection mechanism 50 includes at least one sensor 51, which is mounted on the first stop 30 and is used to detect whether the movable plate 20 carries a qualified battery.

[0030] Batteries without a buffer pad will pass through the first screening gap 30a without being blocked by the first stop 30, while qualified batteries will be intercepted by the first stop 30 and placed on the movable plate 20. Installing the sensor 51 on the first stop 30 allows for the most direct detection of whether the movable plate 20 carries a qualified battery, reducing false detections of batteries without a buffer pad. When installing the sensor 51, it can be positioned directly opposite the carrying area of ​​the movable plate 20, creating close-range detection with the location of the qualified battery, ensuring more direct and sensitive sensing of the presence of qualified batteries.

[0031] The number of sensors 51 installed can be one, two, three, or more. When two or more sensors 51 are installed, they can be spaced apart along the lateral direction of the base 10. For example, three sensors 51 are spaced apart along the lateral direction of the base 10 on the first stop 30, which can cover a wider detection area, adapt to batteries of different widths, and eliminate the need for frequent adjustments to the position of the sensors 51 due to changes in battery width, thus enhancing the versatility of the battery buffer pad missing detection device for batteries of various specifications. The sensor 51 can be an infrared sensor 51, capable of sensing whether there is a qualified battery on the movable plate 20.

[0032] In other embodiments, the detection mechanism 50 may also be a pressure sensor disposed on the movable plate 20. When a qualified battery is blocked and stops on the movable plate 20, the pressure sensor can detect that a qualified battery is carried on the movable plate 20 and output a sensing signal.

[0033] refer to Figure 1 In an optional embodiment of this application, the battery buffer pad missing detection device further includes a second stop 60 disposed on the inclined surface 10a. The second stop 60 is located on the transmission path of the battery sliding down the inclined surface 10a to the opening 10b. A second screening gap 60a is formed between the second stop 60 and the inclined surface 10a to screen out batteries that exceed the qualified thickness.

[0034] A second stop 60 is set on the transmission path of the battery sliding along the inclined surface 10a to the opening 10b. When the overall thickness of the battery exceeds the qualified thickness, it will be blocked by the second stop 60 and cannot enter the area of ​​the movable plate 20 at the opening 10b. Only qualified batteries and batteries without a buffer pad can pass through the second screening gap 60a and enter the screening stage of the first stop 30. Therefore, the setting of the second stop 60 can intercept and screen out batteries that exceed the qualified thickness. Combined with the first stop 30, it can integrate battery thickness testing and buffer pad identification, and achieve the screening of batteries that meet the standard thickness and have a buffer pad attached, which greatly improves production efficiency, further ensures product quality, and reduces rework costs.

[0035] refer to Figure 1In an optional embodiment of this application, the battery buffer pad missing detection device further includes a conveying mechanism 70, the position of which corresponds to the opening 10b, for receiving qualified batteries falling from the opening 10b and conveying them to the next processing station.

[0036] Specifically, through the dual screening of the first stop 30 and the second stop 60, it is confirmed that the movable plate 20 carries qualified batteries with appropriate thickness and attached sponge pads. After the movable plate 20 opens the opening 10b, the qualified batteries will fall from the opening 10b onto the conveying mechanism 70 due to gravity. The conveying mechanism 70 directly receives the qualified batteries falling from the opening 10b, and can stably transport the qualified batteries to the next processing position without manual intervention. This connects the battery buffer pad missing inspection process with the next production process, reduces manual battery handling, further improves the automation level of the battery buffer pad missing detection device, and greatly improves production efficiency.

[0037] Optionally, the conveying mechanism 70 can use a conveyor belt in conjunction with a motor and other components to receive and transport qualified batteries to the next processing station.

[0038] refer to Figure 1 and Figure 3 In an optional embodiment of this application, a first stop 11 and a second stop 12 are respectively provided on both sides of the base 10 on the inclined surface 10a, and the first stop 11 and the second stop 12 extend along the inclined direction of the inclined surface 10a.

[0039] The first stop 11 and the second stop 12 located on both sides of the base 10 can restrict the battery from sliding in the area between the first stop 11 and the second stop 12. This prevents the battery from shifting to either side of the base 10 and sliding off the inclined surface 10a due to minor vibrations or operational errors, ensuring that the battery flows accurately to the subsequent first stop 30, second stop 60, and through-hole 10b. This ensures the stability and accuracy of battery delivery and improves the reliability of the battery buffer pad missing detection device. In addition, the first stop 11 and the second stop 12 can also reduce the frequency of manual adjustment of the battery orientation, improving production efficiency.

[0040] For details, please refer to Figure 1 , Figure 3 and Figure 4 The first stop 30 includes a first support arm 31, a second support arm 32 and a cross arm 33. The first support arm 31 and the second support arm 32 are mounted on the base 10. The cross arm 33 is located between the first support arm 31 and the second support arm 32. The bottom surface of the cross arm 33 and the inclined surface 10a form a first screening gap 30a.

[0041] The horizontal arm 33 is fixed to the base 10 by the first support arm 31 and the second support arm 32. When the battery hits the horizontal arm 33, the impact force will be distributed to the base 10 through the first support arm 31 and the second support arm 32, so that the horizontal arm 33 can resist the impact force when the battery slides down, reduce the local bending of the horizontal arm 33, and ensure the stability of the first screening gap 30a between the bottom surface of the horizontal arm 33 and the inclined surface 10a.

[0042] Optionally, both the first support arm 31 and the second support arm 32 can be mounted on the base 10 using bolts, screws, or other fixing components.

[0043] Further references are available. Figure 1 , Figure 3 and Figure 4 The first stop 11 is provided with a first slot 11a, and the second stop 12 is provided with a second slot 12a corresponding to the position of the first slot 11a. The end of the first support arm 31 away from the horizontal arm 33 is engaged in the first slot 11a, and the end of the second support arm 32 away from the horizontal arm 33 is engaged in the second slot 12a.

[0044] The first slot 11a and the second slot 12a, respectively formed on the first stop 11 and the second stop 12, provide precise installation positions for the first support arm 31 and the second support arm 32, respectively. During installation, simply align the ends of the first support arm 31 and the second support arm 32 with the corresponding first slot 11a and the second slot 12a and insert them to quickly complete the initial positioning of the first stop 30. This eliminates the need for repeated measurements of the positions of the first support arm 31 and the second support arm 32, improving assembly efficiency and accuracy, and reducing the skill requirements for operators. After the first support arm 31 is inserted into the first slot 11a and the second support arm 32 is inserted into the second slot 12a, the groove walls of the first slot 11a and the second slot 12a can limit the corresponding first support arm 31 and the second support arm 32, thereby ensuring that the horizontal arm 33 can be accurately mounted above the inclined surface 10a and ensuring that the first screening gap 30a has a consistent height throughout the entire horizontal range.

[0045] In an optional embodiment of this application, when the second stop 60 is also provided on the inclined surface 10a of the base 10, the structure of the second stop 60 can also be the same as the structure of the first stop 30, the difference being that a second screening gap 60a is formed between the bottom surface of the second stop 60 and the inclined surface 10a.

[0046] refer to Figure 1 In an optional embodiment of this application, the battery buffer pad missing detection device further includes a material box 80, which is located at the downstream end of the inclined surface 10a and is used to collect batteries with missing buffer pads that have passed through the first screening gap 30a.

[0047] By precisely aligning the material box 80 with the downstream end of the inclined surface 10a of the base 10, batteries without buffer pads can slide naturally into the material box 80 along the inclined surface 10a after passing through the first screening gap 30a. This achieves automatic centralized collection of batteries without buffer pads, eliminating the need for manual picking and facilitating battery patching, thus improving production efficiency. Furthermore, the material box 80 prevents batteries without buffer pads from slipping onto the ground and causing scratches on the battery's outer surface, ensuring that the batteries are still suitable for rework and repair, and reducing the direct scrap rate.

[0048] Combination Figures 1 to 3 The specific working process of the battery buffer pad missing detection device according to the embodiments of this application is described below: Batteries are picked up manually or by a robotic arm and placed on the inclined surface 10a of the base 10, allowing them to slide freely down the inclined surface 10a. Batteries exceeding the acceptable thickness are blocked by the second stop 60, while batteries of acceptable thickness pass through the second screening gap 60a and continue to slide along the inclined surface 10a until they reach the movable plate 20 at the opening 10b. Batteries without cushioning pads continue to slide through the first screening gap 30a and continue to slide along the inclined surface 10a until they reach the material tray at the downstream end of the inclined surface 10a. Acceptable batteries with cushioning pads are blocked by the first stop 30 and remain on the movable plate. On the first stop 30, the sensor 51 of the detection mechanism 50 detects that the movable plate 20 carries a qualified battery and outputs a sensing signal. The drive cylinder 41 of the drive mechanism 40 drives the connecting plate 42 to rotate, which in turn drives the movable plate 20 to rotate and open the opening 10b. The qualified battery loses the support of the movable plate 20 and falls onto the conveying mechanism 70. The conveying mechanism 70 receives the qualified battery and transports it to the next processing position. The drive cylinder 41 of the drive mechanism 40 drives the connecting plate 42 to rotate, which in turn drives the movable plate 20 to rotate and reset and close the cover to the opening 10b, waiting to receive the next battery.
