Description

Technical Field

[0001] This utility model relates to the field of circuit testing, and in particular to a circuit offset detection device after COF and glass bonding. Background Technology

[0002] With the rapid development of display technology, the bonding process between COF and glass substrate has been widely used in LCD and OLED display panels. As a key component connecting the driver chip and the glass substrate, the precise alignment of the COF circuitry directly affects the display effect and reliability of the display panel. If the COF circuitry shifts during bonding, it can lead to display abnormalities or even render the entire panel unusable. Therefore, after the COF and glass bonding is completed, precise detection of circuitry shifts is essential, and defective products must be promptly rejected.

[0003] Currently, in existing detection devices, the sorting process still often requires manual operation by the operator. After judging the product status, the staff needs to manually place the defective and qualified products into different collection areas. This process is not only slow, but as the working time increases, the operator's fatigue will further lead to a decrease in sorting speed and an increase in error rate. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a COF and glass bonding line offset detection device. The device uses a circular conveyor belt to realize continuous product transportation, combined with vision inspection module detection, and cylinder and bump driven sorting action. Only manual feeding is required. The device can automatically complete the transportation, inspection, judgment of good and bad products and sorting and collection.

Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0020] See appendix Figures 1 to 4As shown, a COF and glass bonding line offset detection device in this embodiment includes: a base 1, a vision inspection module 4, multiple support platforms 5, an annular block 8, and a power source. An annular conveyor belt 2 is installed on the top of the base 1, and a waste product unloading platform 6 and a good product unloading platform 7 are fixedly connected to the side walls of the base 1. The vision inspection module 4 is installed on the top of the base 1. Multiple support platforms 5 are spaced apart on the top of the conveyor belt 2 along its conveying direction. Each support platform 5 includes a support plate 51 for carrying the product. The support plate 51 is connected to the conveyor belt 2... The top rotating connection has a pair of support arms 56 fixedly installed at the bottom of the support plate 51. The inner side of the pair of support arms 56 is rotatably connected to rollers 57 via a rotating shaft. The annular block 8 is fixedly installed on the top of the base 1 and is arranged around the conveyor belt 2. The bottom of the rollers 57 abuts against the top of the annular block 8. The top of the annular block 8 is equipped with a protrusion 10 corresponding to the position of the good product unloading platform 7. The power source is installed on the top of the base 1 and corresponds to the position of the waste product unloading platform 6. The power source is used to drive the support plate 51 to rotate around the rotating shaft so as to achieve the tilting and sliding of the defective products.

[0021] In this embodiment, the operator places the COF-bonded glass product to be inspected on the support plate 51 of the support platform 5. The circular conveyor belt 2 starts, driving all the support platforms 5 on it to move along a predetermined trajectory, sequentially delivering the product to the area below the vision inspection module 4. When the support platform 5 carrying the product moves directly below the vision inspection module 4, the circular conveyor belt 2 pauses briefly. The vision inspection module 4 quickly captures a clear image of the COF circuit using a high-resolution camera and a dedicated light source. The built-in image processing software immediately analyzes the image, accurately measures the key dimensions and pin positions of the circuit, and compares them with preset tolerance ranges to detect any deviations, thereby determining whether the product is qualified or unqualified. If the product is determined to be unqualified, the control system issues a command, and the power source forces the support plate 51 to rotate at an angle. Defective products on the support plate 51 slide off due to tilting and fall into the waste unloading table 6 for centralized collection and processing. If a product is judged to be qualified, the cylinder 9 will not move, the support plate 51 will remain horizontal, and the product will continue to move forward with the circular conveyor belt 2. On the forward path of the circular conveyor belt 2, the rollers 57 at the bottom of the support platform 5 always roll on the top of the circular block 8, providing stable support. When qualified products pass above the good product unloading table 7, the rollers 57 travel to the protrusions 10 fixed on the circular block. The protrusions 10 lift the rollers 57, thereby forcing the support plate 51 to tilt again. Qualified products on the support plate 51 slide off and fall into the good product unloading table 7, completing the automatic collection of qualified products. The entire process only requires manual loading, achieving automatic sorting, improving detection efficiency, and is suitable for mass production scenarios.

[0022] See appendix Figure 2As shown, the support platform 5 also includes a fixing block 52, which is fixed to the top of the annular conveyor belt 2. A support shaft 55 is fixedly installed on the fixing block 52. A pair of connecting blocks 53 are fixedly connected to the bottom of the bearing plate 51. The support shaft 55 is rotatably connected to the pair of connecting blocks 53.

[0023] In this embodiment, the fixing block 52 securely mounts the entire support platform 5 onto the annular conveyor belt 2, and the support shaft 55 serves as the physical axis for the rotation of the carrier plate 51, enabling the carrier plate 51 to rotate around the support shaft 55 at an angle, thereby achieving the sorting purpose.

[0024] See appendix Figure 2 As shown, a pair of torsion springs 54 are sleeved around the support shaft 55, and the two ends of the torsion springs 54 are fixedly connected to the fixing block 52 and the connecting block 53, respectively.

[0025] In this embodiment, after the support plate 51 is flipped over by the power source or the protrusion 10, the elastic potential energy stored in the torsion spring 54 will drive the support plate 51 to automatically spring back to the horizontal position.

[0026] See appendix Figure 4 As shown, the power source includes a cylinder 9, which is mounted on the top of the base 1. The output end of the cylinder 9 is key-connected to an abutment ball 11, and the cylinder 9 can drive the abutment ball 11 to abut against and lift the bottom of the support plate 51.

[0027] In this embodiment, the cylinder 9 moves linearly after receiving the electronic control signal. When a defective product is detected, the cylinder 9 moves quickly, and the abutment ball 11 at its output end pushes the bottom of the support plate 51, actively driving the support plate 51 to flip.

[0028] See appendix Figure 1 As shown, it also includes a bracket 3, which is mounted on the top of the base 1, and the vision inspection module 4 is mounted on the bracket 3.

[0029] In this embodiment, the bracket 3 is used to elevate and fix the visual inspection module 4, enabling it to take pictures of the product from above and adjust to the optimal working height and angle.

[0030] See appendix Figure 3 As shown, the top surface of the protrusion 10 is an arc surface.

[0031] See appendix Figures 1 to 2 As shown, the top surface of the support plate 51 is provided with an anti-slip structure, which is an anti-slip texture.

[0032] In this embodiment, the anti-slip texture is used to increase the friction between the support plate 51 and the top product, so as to prevent the product from being displaced by centrifugal force during the movement of the annular conveyor belt 2.

[0033] Working principle:

[0034] The operator places the COF-bonded glass product to be inspected onto the support plate 51 of the support platform 5. The circular conveyor belt 2 starts, moving all the support platforms 5 along a predetermined trajectory, sequentially delivering the product to the area below the vision inspection module 4. When the support platform 5 carrying the product moves directly below the vision inspection module 4, the circular conveyor belt 2 pauses briefly. The vision inspection module 4 uses a high-resolution camera and a dedicated light source to quickly capture a clear image of the COF circuit. The built-in image processing software immediately analyzes the image, accurately measures the key dimensions and pin positions of the circuit, and compares them with preset tolerance ranges to detect any deviations, thereby determining whether the product is qualified or unqualified. If the product is determined to be unqualified, the control system will issue an instruction. The power source forces the support plate 51 to tilt, causing defective products on the support plate 51 to slide off and fall into the waste unloading platform 6 for collection and processing. If a product is deemed qualified, the cylinder 9 will not operate, the support plate 51 will remain horizontal, and the product will continue to move forward with the circular conveyor belt 2. Along the forward path of the circular conveyor belt 2, the rollers 57 at the bottom of the support platform 5 will always roll on top of the circular block 8, providing stable support. When a qualified product passes above the good product unloading platform 7, the rollers 57 will travel to the protrusion 10 fixed on the circular block. The protrusion 10 will lift the rollers 57, thereby forcing the support plate 51 to tilt again. The qualified products on the support plate 51 will then slide off and fall into the good product unloading platform 7, completing the automatic collection of qualified products.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
