Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a double-sided pad detection device for labels. Background Technology

[0002] In the production process of cylindrical lithium batteries, the faceplate component is involved. Its material is PET, and its thickness is 0.25mm. On the production line, accurate inspection of the faceplate is crucial, especially the ability to effectively detect double-sided faceplates (two or more faceplates). Previously, faceplate inspection relied heavily on manual methods. However, manual inspection has many drawbacks, such as low efficiency (difficulty in quickly inspecting large quantities of products), insufficient accuracy (prone to missed or false detections), and the inability to provide real-time feedback. When a faceplate problem is detected, it's difficult to promptly prompt the production line to take appropriate action, such as halting production or issuing alarms. This results in a large number of batteries with faceplate problems flowing into subsequent processes, requiring rework and severely impacting the smooth and efficient operation of the production line.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: a double-sided label pad 6 detection device, including a workbench 1, a shelf 2 and a column 3 on the workbench 1, a top seat 4 rotatably connected to the top of the column 3, a plurality of electric telescopic rods 5 fixedly connected to the bottom of the top seat 4, a face pad 6 sleeved on the output end of the electric telescopic rods 5, a bracket 7 fixedly connected to the workbench 1 on the outside of the shelf 2, an optical fiber amplifier 8 fixedly connected to one side of the bracket 7 through a fixing assembly 10, a through-beam sensor 9 fixedly connected to the end of the transverse section of the bracket 7, the face pad 6 can pass through the inside of the through-beam sensor 9 when the top seat 4 rotates, the optical fiber amplifier 8 is electrically connected to the through-beam sensor 9, the fixing assembly 10 includes a mounting rod 101 and a column cap 102, the column cap 102 is sleeved on one end of the mounting rod 101, the other end of the mounting rod 101 is fixedly connected to the optical fiber amplifier 8, and an insertion hole 12 is opened on the bracket 7. The mounting rod 101 is inserted into the socket 12. The mounting rod 101 has a slot 107. A block 103 is fixedly connected to the cap 102. A locking block 104 is slidably connected inside the block 103. The locking block 104 is inserted into the slot 107. A pull rod 105 is fixedly connected to the end of the locking block 104 away from the slot 107. A spring 106 is sleeved on the pull rod 105. The two ends of the spring 106 are fixedly connected to the side wall of the locking block 104 and the block 103 away from the locking block 104, respectively. A first inclined surface 16 is provided at the end of the mounting rod 101 away from the fiber amplifier 8. A second inclined surface 17 is provided on the locking block 104 corresponding to the position of the first inclined surface 16. A protective pad 11 is fixedly connected to the pressing surface of the cap 102. The protective pad 11 is made of elastic rubber.

[0022] In this embodiment, by setting up an optical fiber amplifier 8 and a through-beam sensor 9, and utilizing their detection principle of the difference in light transmittance between different layers of pads 6, the presence of double-sided pads 6 (two or more pads 6) in the product can be effectively detected, achieving automated detection. Compared with manual detection, this greatly improves detection efficiency and accuracy, and can provide real-time feedback on detection results, ensuring smooth operation of the production line. Simultaneously, the fixing component 10 facilitates the assembly and disassembly of the optical fiber amplifier 8, allowing for quick removal of faulty optical fiber amplifiers 8 for maintenance and replacement. When installing the column cap 102, the first inclined surface 16 and the second inclined surface 17 are used... The mutual compression between the blocks allows the locking block 104 to overcome the resistance of the spring 106 and retract into the interior of the block 103. After the locking block 104 is aligned with the slot 107, it is quickly inserted into the slot 107 under the elastic force of the spring 106, without the need for additional operations, thus simplifying the installation and fixing steps of the column cap 102. The elastic rubber protective pad 11 fixed on the pressing surface of the column cap 102 can act as a buffer when the operator presses the column cap 102 to install the fiber optic amplifier 8, avoiding discomfort or damage to the hands.

[0023] Example 2: As Figure 3 - Figure 4 As shown, a guide groove 15 is provided on the mounting rod 101, and a limiting rod 13 is fixedly connected to the inner wall of the insertion hole 12 at the position corresponding to the guide groove 15. The limiting rod 13 is locked inside the guide groove 15. A guide rod 14 is fixedly connected to the inner wall of the column cap 102, and the guide rod 14 is locked inside the guide groove 15.

[0024] In this embodiment, the guide groove 15 on the mounting rod 101 and the limiting rod 13 on the inner wall of the socket 12 cooperate with each other to limit the fiber optic amplifier 8, preventing it from rotating after installation and affecting its use. The guide rod 14 on the inner side of the cap 102 is inserted into the guide groove 15, which can guide and limit the cap 102 during installation, so that the locking block 104 can be quickly aligned with the slot 107, improving the convenience and efficiency of inserting the locking block 104 into the slot 107.

[0025] The working principle of this embodiment: In the production of cylindrical lithium batteries, the detection of the pads 6, especially double-sided pads 6 (two or more pads 6), is very important. When this double-sided pad 6 detection device is in operation, the product to be tested is first placed on the shelf 2 on the workbench 1. Then, the top seat 4 can rotate on the top of the column 3. The output ends of several electrically telescopic rods 5 fixedly connected to its bottom are fitted with pads 6. By controlling the rotation of the top seat 4, the pads 6 rotate and pass through the inside of the through-beam sensor 9. When the pads 6 pass through the inside of the through-beam sensor 9, the through-beam sensor 9 will generate a corresponding signal based on the light transmittance of the pads 6. Due to different numbers of layers... The light transmittance of the face pads 6 (such as single face pad 6, double face pad 6, etc.) varies, resulting in differences in the signals generated by the through-beam sensor 9. These signals are transmitted to the electrically connected fiber optic amplifier 8, which amplifies and processes the signals. Based on pre-set standards (such as values ​​calibrated using a single face pad 6), it determines whether the passing face pad 6 is a single pad or a double face pad 6 (two or more face pads 6). If a non-compliant face pad 6 is detected, it can be promptly fed back to the relevant control system of the production line, allowing the production line to take appropriate actions such as pausing or issuing alarms to prevent defective products from flowing into subsequent processes, thereby ensuring the overall quality of the cylindrical lithium... The efficient and smooth operation of the battery production line is achieved through the following steps in the installation of the fiber optic amplifier 8: First, the mounting rod 101 is inserted into the socket 12 on the bracket 7. The limiting rod 13 inside the socket 12 is engaged in the guide groove 15 to prevent the fiber optic amplifier 8 from rotating and affecting its use. Then, the cap 102 is placed on the end of the mounting rod 101. The guide rod 14 inside the cap 102 acts as a guide and limiter when the cap 102 is placed on the mounting rod 101, allowing the subsequent locking block 104 to quickly align with the locking groove 107. After the cap 102 is placed on the mounting rod 101, the cap 102 is pressed down, and the first inclined surface 16 on the mounting rod 101 and the first inclined surface 16 on the locking block 104 are engaged. The two inclined planes 17 press against each other, causing the locking block 104 to overcome the resistance of the spring 106 and retract into the square block 103. When the locking block 104 is aligned with the slot 107, it is quickly inserted into the slot 107 under the elastic force of the spring 106, thereby achieving the purpose of fixing the fiber amplifier 8. When pressing the cap 102, the protective pad 11 on the pressing surface can avoid hand discomfort. If you want to disassemble the fiber amplifier 8, you only need to pull the lever 105 to make the locking block 104 overcome the resistance of the spring 106 and disassemble it from the slot 107. Then, remove the cap 102 from the mounting rod 101 and disassemble the fiber amplifier 8.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
