[0023] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0024] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it.

[0025] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,Adhesive tape is a flexible material, which may be deformed by external factors after being attached. This flexibility makes the adhesive tape present irregular shapes after being attached, which is a challenge for traditional camera vision systems because they usually rely on the geometric shape and surface features of objects for detection and recognition.

[0026] Traditional camera vision systems may be affected by the distortion or bending of the tape, resulting in an inability to accurately detect the quality or position of the tape. This may affect the efficiency and quality of the production line, because defective products may pass through the detection system without being discovered in time, thereby causing problems in subsequent processes. Based on this, the present application provides a visual inspection device for adhesive tape bonding and clamping, an image acquisition part 1, including an adjustment device 2 installed below it, for adjusting the distance of image acquisition;

[0027] The clamping part includes a pair of clamping plates 4, at least two of which are symmetrically arranged, and a wiring harness 7 is arranged between the two pair of clamping plates 4;

[0028] A control component is provided below the clamping plate 4 to control the clamping plate 4 to move away from or close to the wire harness 7 , so as to restrict the wire harness 7 .

[0029] On the automated production line, after the tape is attached to the harness 7 by the equipment, the traditional camera vision system may not be able to accurately detect the quality of the tape. However, after the introduction of this tape-attaching and -clamping visual inspection system, first, the image acquisition unit 1 will automatically adjust the distance according to the condition of the attached tape to ensure that a clear image can be obtained. Then, the clamping plates 4 of the clamping unit will clamp the harness 7, and the control component will ensure that the harness 7 remains stable during the inspection process. In this way, the system can accurately detect the quality of the tape, avoiding the problems of missed detection or false detection that may exist in the traditional system, thereby improving the efficiency of the production line and product quality.

[0030] The adjustment device 2 is one of the common components used for reciprocating linear adjustment in the mechanical field, such as a combination of a cylinder, a motor threaded rod and a slide rail, and a manual adjustment component. From the perspective of use, the combination of a motor threaded rod and a slide rail is preferred;

[0031] The control assembly includes a rack device 9 arranged below the clamping plate 4 , and a control motor 6 is arranged at the bottom between the racks for controlling the movement of the rack device 9 .

[0032] When the wire harness 7 needs to be clamped and tested, the control motor 6 is started to drive the rack device 9. By controlling the motor 6, the rack device 9 can move upward or downward, thereby adjusting the position of the clamping plate 4 to clamp the wire harness 7. Such a design can ensure the accuracy and stability of the clamping plate 4 when clamping the wire harness 7, thereby improving the accuracy and reliability of the detection.

[0033] In the whole system, the introduction of control components further enhances the automation and precision of the system. By controlling the precise adjustment of the motor 6, the system can quickly respond and adapt to different working scenarios, ensuring that the harness 7 is stably clamped, thereby ensuring the accuracy and stability of the detection process.

[0034] In summary, through the combination of the rack device 9 and the control motor 6, the control component can accurately control the position of the clamping plate 4, thereby ensuring the stable clamping of the wire harness 7, thereby improving the accuracy and stability of the detection. This design can effectively optimize the production process of the production line, improve product quality, and reduce the defective product rate, thereby bringing economic benefits and production efficiency improvements.

[0035] The clamping plate 4 is transparent and has a smooth surface.

[0036] One end of each of the two clamping plates 4 is provided with a spring 8 , and the spring 8 is movably connected to the spring 8 , so as to control the clamping force of the clamping plates 4 on the wire harness 7 .

[0037] A support frame 3 for supporting is arranged below the clamping plate 4 , and the bottom of the support frame 3 is combined with the control motor 6 .

[0038] First, the clamping plate 4 is transparent so that the camera can clearly capture the state of the tape on the wire harness 7 after clamping;

[0039] Secondly, the surface of the splint 4 is flat, which is conducive to the flattening of the adhesive tape and facilitates the camera to accurately take pictures and detect.

[0040] In addition, one end of each of the two clamping plates 4 is provided with a spring 8, and is movably connected to the spring 8, for controlling the clamping force of the clamping plates 4 on the wire harness 7. This design allows the clamping force of the clamping plates 4 to be adjusted according to the different characteristics and requirements of the wire harness 7, ensuring the accuracy and stability of the clamping force.

[0041] At the same time, a support frame 3 for supporting is provided below the clamping plate 4, and the bottom of the support frame 3 is combined with the control motor 6. The function of this support frame 3 is to ensure the stability and reliability of the clamping plate 4 during the clamping process, thereby further improving the clamping effect of the system and the accuracy of detection.

[0042] In the embodiment, when the control motor 6 is started, it controls the position of the clamping plate 4 through the rack device 9, and controls the clamping force of the wire harness 7 by adjusting the tension of the spring 8. In this way, the system can flexibly adjust the clamping force and position according to actual conditions to ensure that the wire harness 7 is stably clamped, thereby ensuring the accuracy and stability of the detection process.

[0043] In summary, the design of the clamping part improves the visibility, clamping effect and stability of the system through the transparent clamping plate 4, the flat surface, the clamping force controlled by the spring 8 and the support of the support frame 3, thereby optimizing the performance of the tape sticking and clamping visual inspection system and improving product quality and production efficiency.

[0044] A light source 5 is provided on one side of the support frame 3 , and the light source 5 is matched with the image acquisition part 1 to provide lighting for image acquisition.

[0045] The support frame 3 ensures the stability of the clamping plate 4 and provides necessary lighting support for image acquisition by arranging a light source 5 .

[0046] In the embodiment, a light source 5 is provided on one side of the support frame 3. The light source 5 is used in combination with the image acquisition unit 1, and is generally a dedicated light source for a camera, such as a fluorescent light source, an LED light source, a laser light source, a halogen light source, etc. Different light sources can be used according to different needs to illuminate the detection area of ​​the adhesive tape. This ensures that clear images can be obtained under various light conditions, thereby improving the accuracy and reliability of detection.

[0047] By setting the light source 5, the system can eliminate or reduce the impact of insufficient or uneven light, ensuring the brightness and clarity of the image. This is very important for testing the quality of the tape, because only under sufficient light can the tape's fit, surface features and possible defects be accurately observed.

[0048] In addition, the setting of light source 5 also helps to improve the stability and reliability of the system because it can reduce image deviation or noise caused by light changes, ensuring the consistency and accuracy of the detection process.

[0049] In summary, the design of arranging the light source 5 on the support frame 3 provides the necessary image acquisition conditions for the tape sticking and clamping visual inspection system by providing stable and sufficient lighting, further enhances the inspection performance and stability of the system, and improves product quality and production efficiency.

[0050] In addition to the provision of the light source 5 , the types of the image acquisition component 1 can be further expanded to meet different detection requirements and environmental conditions.

[0051] As for the image acquisition unit 1, in addition to common industrial cameras, high-definition cameras, infrared cameras, etc. may also be considered. High-definition cameras can provide clearer and more detailed images, while infrared cameras can achieve better imaging effects under low-light conditions.

[0052] Furthermore, by setting up multiple cameras, images of the adhesive tape being pasted and clamped can be captured from different angles and directions, providing more comprehensive detection information and enhancing the detection capability of the system.

[0053] At the same time, a stereo vision system can be introduced to realize three-dimensional detection of tape sticking and clamping, more accurately analyze the tape's fit and surface features, and improve detection accuracy and reliability.

[0054] In addition to hardware equipment, the image acquisition component may also include image processing algorithms, such as edge detection, pattern matching, deep learning, etc., to further improve the accuracy and efficiency of detection by performing real-time processing and analysis of the acquired images.

[0055] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
