Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a CCD violet light source adhesive testing device for vehicle interior trim parts. Background Technology

[0002] Some interior trim components, such as door panels and dashboards, utilize composite processes, where soft materials are applied to the surface of a rigid injection-molded frame to improve the product's appearance and comfort. In the composite processing steps, hot melt adhesive is typically applied to the workpiece surface, and the composite process is completed through a subsequent thermal bonding step.

[0003] However, during the adhesive application process, it is crucial to ensure the uniformity of the adhesive to guarantee the stability of the retro finish. Therefore, it is often necessary to inspect the quality of the adhesive application after it has been applied to the workpiece. Current inspection methods utilize single-point sensors for sampling inspection, which cannot achieve full coverage of all areas. Consequently, there is a significant risk of untreated adhesive areas leaking out, posing a product quality and safety risk, and resulting in unsatisfactory monitoring effectiveness.

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, the use of terms such as "first" and "second" in the embodiments of this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0027] This utility model embodiment provides a device for detecting the adhesive quality of interior trim parts in a vehicle. The workpiece to be tested is conveyed along a first conveying device 200. To accurately convey the workpiece to the position corresponding to the detection device 300 for testing, a guide component 210 is provided at the input end of the first conveying device 200 to guide the workpiece. During the conveying process along the first conveying device 200, the workpiece enters the guide channel 211 and moves under the guidance of the guide channel 211, thereby ensuring that the workpiece's movement trajectory passes precisely through the position corresponding to the detection device 300, thus enabling accurate detection. In this embodiment, the detection device 300... By incorporating a UV light source 310 and a camera assembly 320, ultraviolet light can be irradiated onto the workpiece, causing the adhesive to fluoresce. The camera assembly 320 photographs the fluorescent adhesive-coated surface, and the control system compares and analyzes the acquired image information to detect the adhesive coating status. It should be noted that the control system's comparison and analysis of the images captured by the camera assembly 320 can be implemented using existing technologies, and is not limited here. In this embodiment, the transfer device 500 picks up the unqualified workpieces and transfers them to the second conveyor device 400, where they are uniformly recycled. The technical solution provided in this embodiment enables comprehensive detection of the adhesive coating on the workpiece. After UV irradiation, the camera assembly 320 can photograph and collect image information of the adhesive coating status on the entire surface. The control system can then perform comprehensive detection, making the adhesive detection more thorough and accurate.

[0028] Specifically, such as Figure 1-6 As shown, this utility model embodiment provides a CCD violet light source 310 adhesive coating inspection device for automotive interior trim parts, including a machine base 100. A first conveying device 200, a second conveying device 400, a detection device 300, and a transfer device 500 are configured on the machine base 100. The first conveying device 200 is used to convey the workpiece to be processed along a first predetermined direction, and a guide component 210 is provided at the output end of the first conveying device. The guide component 210 internally defines a position for the workpiece to be processed to be conveyed on the first conveying device 200. A guide channel is provided for guidance; a detection device 300 is suspended above the first conveyor 200, and includes a violet light source 310 for irradiating the workpiece with ultraviolet light and a camera assembly 320 for acquiring visual signals from the workpiece; a second conveyor 400 is disposed beside the first conveyor 200 and extends along a second predetermined direction; it includes a clamping unit 510 that reciprocates between the first conveyor 200 and the second conveyor 400 to transfer the inspected workpiece toward the second conveyor 400. In this embodiment, the camera assembly is a CCD camera.

[0029] In the technical solution provided by this utility model embodiment, during the detection operation, the ultraviolet light source 310 and camera assembly 320 in the detection device 300 are positioned above the first conveying device 200. The workpiece to be detected, guided by the guide assembly, moves along the direction defined by the guide channel with the first conveying device 200, thus moving directly below the detection device 300. At this time, the ultraviolet light source 310 irradiates the adhesive-coated surface of the workpiece with ultraviolet light. The adhesive then fluoresces under the ultraviolet light. It is understood that the adhesive has fluorescent properties and can emit fluorescence after ultraviolet irradiation. It is understood that fluorescent agents can be added to the adhesive to enhance its fluorescent properties, thereby enabling it to emit obvious fluorescence under ultraviolet light. After the adhesive emits fluorescence, the... The machine component 320 photographs the workpiece to collect image information of the glued surface, and transmits the image information to the control system. The control system analyzes the image data to determine the glue application quality. It is worth noting that the ultraviolet light source 310 can illuminate the entire glued surface of the workpiece, and the camera component 320 can take comprehensive pictures of the glued surface, thus achieving a comprehensive inspection of the glued surface. If areas with poor glue quality are found, the clamping unit 510 of the transfer device 500 clamps the workpiece and transfers it to the second conveying device 400. The second conveying device 400 then uniformly transports and retrieves the workpiece. Workpieces that pass inspection continue to be transported by the first conveying device 200 along a predetermined direction to the next processing step. This technical solution allows for inspection during the workpiece's transport along the first conveying device 200, and enables a comprehensive inspection of the glued surface, thereby improving the accuracy and comprehensiveness of the inspection work.

[0030] In this embodiment, as Figure 3 As shown in the illustration, this embodiment provides an example of the specific structure of the detection device 300. The detection device includes a mounting frame 330, which is mounted on the machine base 100 and suspended above the first conveying device 200 via a support rod 331. The camera assembly 320 and the ultraviolet light source 310 are mounted on the mounting frame 330. The support rod 331 allows the mounting frame 330 to be suspended above the first conveying device 200, thereby enabling the ultraviolet light source 310 and the camera assembly 320 to perform the detection work facing downwards.

[0031] In this embodiment, the mounting frame 330 includes two crossbars 332 extending toward the first conveying device 200, and several vertically extending mounting plates 334 are respectively mounted on the two crossbars 332. The ultraviolet light source 310 includes several lamps arranged side by side, and the two ends of each lamp are respectively mounted on the mounting plate 334. The mounting frame 330 also includes a mounting base disposed above the crossbars, and a camera assembly 320 is disposed on the mounting base, with the lens of the camera assembly 320 facing downward between two adjacent lamps. By providing multiple lamps arranged side by side, the ultraviolet light irradiating the workpiece is more uniform, thereby improving the reliability of the adhesive fluorescence and the accuracy of detection.

[0032] In this embodiment, to adjust the illumination direction of the lamp tube and thus make the purple light projected onto the workpiece more uniform, a mounting hole 3331 and a sliding groove 3332 are formed on the mounting plate 334. The sliding groove 3332 is configured as an arc with the mounting hole 3331 as the center and a predetermined radius. Fasteners passing through the mounting hole 3331 and sliding members that limit the sliding within the sliding groove 3332 are provided on the upper end of the lamp tube. When the illumination angle of the lamp tube needs to be adjusted, the fasteners are loosened, allowing the lamp tube to rotate around the fasteners as an axis. This causes the sliding member to slide within the sliding groove 3332, thus completing the adjustment of the lamp tube's illumination angle. The fasteners are then tightened. It is worth noting that in this embodiment, the sliding member can be implemented using bolts, allowing it to be locked. Tightening both components simultaneously ensures that the lamp tube will not move after the angle is adjusted.

[0033] In this embodiment, as Figure 4 As shown in the illustration, this embodiment provides an example of the structure of the transfer device 500. The transfer device 500 includes a first linear module 520 and a second linear module 530. The two ends of the linear modules are respectively located above the first conveying device 200 and the second conveying device 400. The second linear module 530 is arranged vertically and mounted on the first linear module 520, moving back and forth between the first conveying device 200 and the second conveying device 400 along with the first linear module 520. The clamping unit 510 is mounted on the second linear module 530 and moves back and forth vertically along with the second linear module 530. The first linear module 520 and the second linear module 530 can drive the clamping unit 510 to move along both the vertical and horizontal axes, thereby accurately completing the workpiece gripping and transfer work.

[0034] In this embodiment, the clamping unit 510 includes a base, two opposing grippers 512, and a drive unit 513. The drive unit 513 is mounted on the base 511 and is tractively connected to the two grippers 512, driving the two grippers 512 to move towards or away from each other to achieve clamping and releasing actions. In this embodiment, the drive unit 513 is a double-headed cylinder, which can drive the two grippers 512 to move closer or further apart, thereby achieving clamping and releasing actions on the workpiece.

[0035] In this embodiment, to ensure that the workpiece is not damaged due to excessive clamping force during the clamping process, such as... Figure 4 As shown, the gripper 512 is configured to have elastic cushioning. The gripper 512 includes a fixing member 5121, a transmission rod 5122, and an elastic member. Specifically, the fixing member 5121 is tractively connected to the drive unit 513. The transmission rod 5122 is slidably connected to the fixing member 5121 in the direction toward the other fixing member 5121, and a clamping block 5123 is fixedly mounted on the end of the transmission rod 5122 toward the other fixing member 5121. The elastic member is fitted onto the transmission rod 5122 and is located between the fixing member 5121 and the clamping block 5123 to provide an elastic thrust to the clamping block 5123 in the direction toward the other clamping block 5123.

[0036] During the process of the drive unit 513 driving the gripper 512 to clamp the workpiece, the clamping block 5123 moves toward the workpiece to clamp it. At this time, as the drive unit 513 continuously applies clamping force, the clamping block 5123 gradually compresses the elastic element, causing it to undergo elastic deformation. The deformation of the elastic element absorbs the clamping force, preventing excessive clamping force from damaging the workpiece.

[0037] like Figure 5-6 As shown, in this embodiment, the guiding assembly includes two opposing guide blocks 212, which define a guiding channel. An outwardly expanding guide ramp 213 is provided at the input end of each guide block 212, making the inlet of the guiding channel funnel-shaped. Multiple guide wheels 214 arranged side-by-side are provided along the length of the inner surface of each guide block 212. After the workpiece enters from the input end of the first conveying device 200, it enters the guiding channel 211 under the guidance of the guide ramp 213. At this time, the contact between the workpiece and the guide wheels 214 reduces the coefficient of friction between the workpiece and the inner wall of the guide block 212, allowing it to pass smoothly within the guiding channel.

[0038] In this embodiment, the workpiece to be inspected is conveyed on the first conveying device 200. Simultaneously, the workpiece that passes inspection is also conveyed by the first conveying device 200 to the next process. To ensure that the workpiece to be inspected and the workpiece that passes inspection are conveyed separately and without interference, the first conveying device 200 includes a first conveyor belt 201 and a second conveyor belt 202 equally spaced along a first predetermined direction. The first conveyor belt 201 and the second conveyor belt 202 are respectively positioned opposite to the inspection device 300 and the transfer device 500. A guide assembly is disposed on the first conveyor belt 201, and one end of the transfer device is disposed above the second conveyor belt 202. That is, the first conveyor belt 201... 1. The conveyor belt 1 is used to transport workpieces to be inspected. After inspection, the workpieces can be transferred manually or by themselves onto the second conveyor belt 202, where they are then transported. To distinguish between qualified and unqualified workpieces and to facilitate the transfer device 500 in transferring unqualified workpieces to the second conveyor belt, a stop assembly 220 is provided on the second conveyor belt to block the transported workpieces. The stop assembly 220 includes a lifting cylinder 221 fixedly mounted on the machine base 100. An extension rod is connected to the piston rod of the lifting cylinder 221, extending towards the inside of the second conveyor belt and fixedly connected to a downward-extending stop block 222. That is, when an unqualified workpiece is transferred to the second conveyor belt 202, the lifting cylinder 221 moves the stop block 222 towards the conveyor belt, thereby restricting the movement of the unqualified workpiece on the second conveyor belt 202 and facilitating the transfer device 500 in transferring it towards the second conveyor device 400.

[0039] In this embodiment, in order for the second conveying device 400 to accurately convey the defective workpieces to the next process, a guide component is also provided at the input end of the second conveying device 400, so that the defective workpieces can have a precise movement trajectory corresponding to the next process.

[0040] For those skilled in the art, various other corresponding changes and modifications can be obtained based on the structure and principles disclosed in this utility model, and all such changes and modifications fall within the protection scope of this utility model.
