Description

Technical Field

[0001] This utility model relates to the technical field of foam adhesive appearance inspection, and in particular to a modular device for defect detection and marking in foam adhesive production lines. Background Technology

[0002] Foam adhesive refers to applying an adhesive to a foam substrate and covering it with release paper or release film. It is commonly used for attaching and fixing furniture trims, hooks, etc., and for internal attachment, fixing, and shockproof protection in electronic products such as computers. It has wide applications in home furnishings, electronic products, and automobiles. After production, foam adhesive needs to undergo defect detection to check for surface defects (such as bubbles or scratches). In the prior art, a utility model patent with patent application number 202320117186.3 discloses a foam inspection machine, which mainly consists of a detection station and an industrial camera. When inspecting foam adhesive, the foam adhesive is placed on the detection station, and then the industrial camera performs a visual inspection of the foam adhesive at the detection station. However, this method has the following problems: it cannot mark the detected defective foam adhesive, leading to confusion between defective and normal foam adhesive during subsequent circulation and storage, making it inconvenient to use and difficult to classify and store. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a modular device for defect detection and marking of foam adhesive production lines that can not only perform appearance inspection on foam adhesive, but also mark foam adhesive with appearance defects, reducing the risk of confusion between defective products and normal products. This device is highly reliable and practical.

[0004] This utility model discloses a modular device for defect detection and marking in a foam adhesive production line. It includes a base plate and a belt conveyor, with the belt conveyor fixedly mounted on the base plate and a conveyor belt installed on it. It also includes a collection box A, a collection box B, a moving mechanism, a detection mechanism, a marking mechanism, a pushing mechanism, and a controller. The controller is mounted on the base plate. Collection boxes A and B are both mounted on the base plate, with collection box B located below the right end of the conveyor belt and collection box A located below the middle of the conveyor belt. The detection mechanism and marking mechanism are both mounted on the moving mechanism, which has a moving function, and the marking mechanism has a marking function. The moving mechanism, detection mechanism, and marking mechanism are all connected to the controller, which controls the moving mechanism, detection mechanism, marking mechanism, and pushing mechanism. When performing visual inspection of the foam adhesive, the foam adhesive is first placed on the conveyor belt... The system starts by feeding the upper end of the conveyor belt, then turning it on to transport the foam adhesive to the area below the inspection mechanism. The inspection mechanism performs a visual inspection of the foam adhesive. If any defects are found, the mechanism transmits the information to the controller, which stops the conveyor belt. The controller then marks the defective foam adhesive using a marking mechanism. The defective foam adhesive is then pushed into collection box A by a pushing mechanism. The conveyor belt continues to move, and the next foam adhesive is inspected in the same manner. Foam adhesive that passes the visual inspection is then transported to collection box B for storage. This system not only performs visual inspection of foam adhesive but also marks defective products, reducing the risk of confusion between defective and normal products. It offers high reliability and practicality.

[0005] Preferably, the moving mechanism includes a fixed plate, a hydraulic cylinder, a push rod, a lifting block, and a rotating mechanism. The fixed plate is fixedly mounted on the upper end of the base plate, the hydraulic cylinder is fixedly mounted on the upper end of the fixed plate, the push rod is slidably mounted on the hydraulic cylinder, and the upper end of the push rod is connected to the output end of the hydraulic cylinder. The lifting block is fixedly mounted on the lower end of the push rod and slidably mounted on the fixed plate. The rotating mechanism is mounted on the lifting block, and both the detection mechanism and the marking mechanism are mounted on the rotating mechanism. When testing the foam adhesive, the hydraulic cylinder is opened, and the hydraulic cylinder adjusts the height of the lifting block through the push rod. The lifting block causes the rotating mechanism to adjust the height of the detection mechanism, so that the distance between the detection mechanism and the conveyor belt is a suitable distance for testing. This facilitates the testing of the foam adhesive products on the upper end of the conveyor belt.

[0006] Preferably, the rotating mechanism includes a stepper motor, a rotating shaft, and a mounting block. The stepper motor is fixedly mounted on the rear end of the lifting block, the rotating shaft is rotatably mounted on the lifting block, and the rear end of the rotating shaft is fixedly connected to the output end of the stepper motor. The mounting block is fixedly mounted on the front end of the rotating shaft. The detection mechanism and the marking mechanism are respectively mounted on the lower and upper ends of the mounting block. The stepper motor is a stepper motor with angle self-locking capability. When performing appearance inspection on the products at the top of the conveyor belt, the detection mechanism is positioned on the side closer to the conveyor belt. When a defective product is detected and it is necessary to mark the foam adhesive, the stepper motor is turned on, the rotating shaft rotates, causing the mounting block to rotate the detection mechanism and the marking mechanism, so that the marking mechanism rotates to the side closer to the conveyor belt. The foam adhesive products at the top of the conveyor belt can then be marked by the marking mechanism. This facilitates the marking and inspection of foam adhesive products.

[0007] Preferably, the detection mechanism includes a vision sensor, which is installed at the lower end of the mounting block and connected to the controller. When detecting foam adhesive products on the upper end of the conveyor belt, the foam adhesive can be visually inspected by the vision sensor when it moves below the vision sensor, thus improving convenience.

[0008] Preferably, the marking mechanism includes a servo cylinder and a return ink stamp. The servo cylinder is fixedly mounted on the upper end of the mounting block, and the return ink stamp is mounted on the moving end of the upper part of the servo cylinder. When a defective foam adhesive product is detected, the stepper motor is turned on, which drives the rotating shaft and the mounting block to rotate, thereby driving the servo cylinder and the return ink stamp to rotate, so that the return ink stamp rotates to the side close to the foam adhesive product. Then, the servo cylinder is turned on, causing the return ink stamp to descend. During the descent, the return ink stamp contacts the foam adhesive product, and a mark is printed on the defective product by the return ink stamp.

[0009] Preferably, the pushing mechanism includes a cylinder, a moving rod, and a push plate. The cylinder is fixedly installed at the rear end of the fixed plate, the moving rod is slidably installed on the fixed plate, the front end of the moving rod is connected to the output end of the cylinder, and the push plate is fixedly installed at the front end of the moving rod. The push plate is located on the rear side above the collection box A. After the defective product is marked on the upper end of the conveyor belt, the cylinder is opened, causing the moving rod to drive the push plate forward. During the forward movement, the push plate contacts the defective product, thereby pushing the defective product onto the conveyor belt and storing it in the collection box A.

[0010] Preferably, a light is provided at the upper end of the base plate; this arrangement makes the upper part of the base plate brighter, facilitating the appearance inspection of the product.

[0011] Compared with the prior art, the advantages of this utility model are: it can not only perform appearance inspection on foam adhesive, but also mark foam adhesive with appearance defects, reducing the risk of confusion between defective products and normal products, and has high reliability and practicality.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0019] like Figures 1 to 5The present invention relates to a defect detection device for a foam adhesive production line, comprising a base plate 1, a belt conveyor 2, collection boxes A4 and B5, a moving mechanism, a detection mechanism, a marking mechanism, a pushing mechanism, and a controller. The belt conveyor 2 is fixedly mounted on the base plate 1, and a conveyor belt 3 is mounted on the belt conveyor 2. The controller is mounted on the base plate 1. Collection boxes A4 and B5 are both mounted on the base plate 1, with collection box B5 located below the right end of the conveyor belt 3 and collection box A4 located below the middle of the conveyor belt 3. The detection mechanism and the marking mechanism are both mounted on the moving mechanism, which has a moving function, and the marking mechanism has a marking function. The moving mechanism, detection mechanism, and marking mechanism are all connected to the controller, which controls the moving mechanism, detection mechanism, marking mechanism, and pushing mechanism. When performing visual inspection of the foam adhesive, the foam adhesive is first placed on the conveyor belt... The upper end of belt 3 is connected, and then belt conveyor 2 is turned on, so that conveyor belt 3 transports the foam adhesive to the bottom of the inspection mechanism. The inspection mechanism performs visual inspection on the foam adhesive. When a defect is found in the appearance of the foam adhesive, the inspection mechanism transmits the information to the controller. The controller stops belt conveyor 2 and then controls the marking mechanism to mark the defective foam adhesive. Then, the pushing mechanism pushes the defective foam adhesive at the upper end of conveyor belt 3 into the collection box A4 for storage. Then, belt conveyor 2 drives conveyor belt 3 to continue moving, and the next foam adhesive is inspected in the same way. Foam adhesive that meets the appearance requirements is transported to the collection box B5 for storage. This method can not only perform visual inspection on foam adhesive, but also mark foam adhesive with appearance defects, reducing the risk of confusion between defective products and normal products. It has high reliability and practicality.

[0020] like Figure 1 and Figure 3 The moving mechanism includes a fixed plate 6, a hydraulic cylinder 7, a push rod 8, a lifting block 9, and a rotating mechanism. The fixed plate 6 is fixedly installed on the upper end of the base plate 1. The hydraulic cylinder 7 is fixedly installed on the upper end of the fixed plate 6. The push rod 8 is slidably installed on the hydraulic cylinder 7, and its upper end is connected to the output end of the hydraulic cylinder 7. The lifting block 9 is fixedly installed on the lower end of the push rod 8 and slidably installed on the fixed plate 6. The rotating mechanism is installed on the lifting block 9. The detection mechanism and the marking mechanism are both installed on the rotating mechanism. When testing the foam adhesive, the hydraulic cylinder 7 is opened. The hydraulic cylinder 7 adjusts the height of the lifting block 9 through the push rod 8. The lifting block 9 then causes the rotating mechanism to adjust the height of the detection mechanism, so that the distance between the detection mechanism and the conveyor belt 3 is suitable for testing. This facilitates the testing of the foam adhesive products on the upper end of the conveyor belt 3.

[0021] like Figure 3The rotating mechanism includes a stepper motor 10, a rotating shaft 11, and a mounting block 12. The stepper motor 10 is fixedly mounted on the rear end of the lifting block 9, and the rotating shaft 11 is rotatably mounted on the lifting block 9. The rear end of the rotating shaft 11 is fixedly connected to the output end of the stepper motor 10. The mounting block 12 is fixedly mounted on the front end of the rotating shaft 11. The detection mechanism and the marking mechanism are respectively mounted on the lower and upper ends of the mounting block 12. The stepper motor 10 is a stepper motor with angle self-locking capability. When performing appearance inspection on the products on the upper end of the conveyor belt 3, the detection mechanism is positioned on the side closer to the conveyor belt 3. When a defective product is detected and it is necessary to mark the foam adhesive, the stepper motor 10 is turned on, and the rotating shaft 11 rotates, causing the mounting block 12 to rotate the detection mechanism and the marking mechanism, so that the marking mechanism rotates to the side closer to the conveyor belt 3. The foam adhesive products on the upper end of the conveyor belt 3 can be marked by the marking mechanism, which facilitates the marking and inspection of foam adhesive products.

[0022] The inspection mechanism includes a vision sensor 13, which is installed at the lower end of the mounting block 12 and connected to the controller. When inspecting the foam adhesive product at the upper end of the conveyor belt 3, the foam adhesive can be visually inspected by the vision sensor 13 when it moves below the vision sensor 13, thus improving convenience.

[0023] like Figure 1 , 3 4. The marking mechanism includes a servo cylinder 14 and a back-ink stamp 15. The servo cylinder 14 is fixedly mounted on the upper end of the mounting block 12, and the back-ink stamp 15 is mounted on the moving end of the upper part of the servo cylinder 14. When a defective foam adhesive product is detected, the stepper motor 10 is turned on. The stepper motor 10 drives the rotating shaft 11 and the mounting block 12 to rotate, which in turn drives the servo cylinder 14 and the back-ink stamp 15 to rotate, so that the back-ink stamp 15 rotates to the side close to the foam adhesive product. Then, the servo cylinder 14 is turned on, so that the back-ink stamp 15 descends. During the descent, the back-ink stamp 15 contacts the foam adhesive product and marks the defective product with the back-ink stamp 15.

[0024] like Figure 1 and Figure 5 The pushing mechanism includes a cylinder 16, a moving rod 17, and a push plate 18. The cylinder 16 is fixedly installed at the rear end of the fixed plate 6. The moving rod 17 is slidably installed on the fixed plate 6. The front end of the moving rod 17 is connected to the output end of the cylinder 16. The push plate 18 is fixedly installed at the front end of the moving rod 17 and is located on the rear side above the collection box A4. When a defective product is marked on the upper end of the conveyor belt 3, the cylinder 16 is opened, causing the moving rod 17 to drive the push plate 18 forward. During the forward movement, the push plate 18 contacts the defective product, thereby pushing the defective product on the conveyor belt 3 into the collection box A4 for storage. Example 2

[0025] Based on Embodiment 1, a lighting lamp is provided at the upper end of the base plate 1; through the above-mentioned arrangement, the upper part of the base plate 1 is made brighter, which facilitates the appearance inspection of the product.
