[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a glue line detection image acquisition device, comprising: a support leg 1, a conveyor table 2 fixedly connected to the upper surface of the support leg 1, a fixing frame 31 fixedly connected to the side surface of the conveyor table 2, a positioning rod 317 fixedly connected to the center of the inner surface of the fixing frame 31, a detection camera 318 fixedly connected to the end of the positioning rod 317 away from the fixing frame 31, a cleaning slide plate 314 movably connected to the outer surface of the detection camera 318, a cleaning brush 316 fixedly connected to the inward side of the cleaning slide plate 314, an intermittent component 3 fixedly connected to the side surface of the cleaning slide plate 314, the intermittent component 3 including a counting sensor 319, the intermittent component 3 drives the cleaning slide plate 314 to move periodically, and the cleaning slide plate 314 drives the cleaning brush 316 to clean the surface of the detection camera 318.

[0025] In use, the counting sensor 319 and the movable ring 38 are used to automatically start the drive motor 34 in the motor box 33 when the counting sensor 319 detects that the number of adhesive lines has reached the set value. The drive motor 34 drives the movable ring 38 to reciprocate through the rotating disk 35 and the rotating rod 36. The movable ring 38 pushes the cleaning slide plate 314 to slide along the limit rod 315 through the linkage rod 311 and the push rod 313, so that the cleaning brush 316 cleans the surface of the detection camera 318. The positioning seat 312 and the guide rod 310 ensure stable movement and avoid shaking during cleaning. This improves the problem of blurry images caused by untimely manual cleaning in traditional methods and ensures the accuracy of adhesive line detection.

[0026] A protective box 32 is fixedly connected to the outer surface of the fixed frame 31. A motor box 33 is fixedly connected inside the protective box 32. A drive motor 34 is installed inside the motor box 33. A rotating disk 35 is fixedly connected to the output end of the drive motor 34. A rotating rod 36 is fixedly connected to the eccentric surface of the rotating disk 35. A limit ring 37 is fixedly connected to the side of the rotating rod 36 away from the drive motor 34. A movable ring 38 is movably connected to the side surface of the rotating rod 36. A limit groove 39 is formed through the outer surface of the movable ring 38. A guide rod 310 is fixedly connected to one side surface of the movable ring 38. A linkage rod 311 is fixedly connected to the other side surface of the movable ring 38. A push rod 313 is fixedly connected to the side of the linkage rod 311 away from the movable ring 38.

[0027] A positioning seat 312 is movably connected to the outer surface of the connection between the push rod 313 and the linkage rod 311. The outer surface of the positioning seat 312 is fixedly connected to the side surface of the motor box 33 facing the linkage rod 311. Two sets of positioning seats 312 are symmetrically arranged on both sides of the motor box 33. Another set of positioning seats 312 is sleeved on the outer surface of the guide rod 310. A cleaning slide plate 314 is fixedly connected to the end of the push rod 313 away from the linkage rod 311. A cleaning brush 316 is fixedly connected to the inward end of the cleaning slide plate 314.

[0028] Limiting rods 315 are connected through the upper and lower ends of the cleaning slide plate 314. The two ends of the limiting rods 315 are fixedly connected to the inner surface of the fixing frame 31. The fixing frame 31 is fixedly connected in two sets to the two side surfaces of the conveyor table 2. The cleaning slide plate 314 and the cleaning brush 316 are slidably connected to the downward-facing surface of the detection camera 318. A limiting groove 39 is connected through the front and rear ends of the movable ring 38 and fits onto the outer surface of the rotating rod 36. The movable ring 38 is movably connected to the inner surface of the rotating rod 36 facing the limiting ring 37, and the limiting ring 37 is movably connected to the surface of the movable ring 38 away from the rotating disk 35. The rotating rod 36 is fixedly connected to the surface of the rotating disk 35 away from the center. The counting sensor 319 is fixedly connected to the upper surface of the protective box 32.

[0029] In use, the entire device is based on the conveyor table 2 supported by the support legs 1. As the adhesive line is conveyed along the conveyor table 2, the detection camera 318, fixed to the inner surface of the fixing frame 31 by the positioning rod 317, captures images of the adhesive line. The protective box 32 on the side surface of the fixing frame 31 provides protection for the intermittent component 3. The counting sensor 319 on the outer surface of the protective box 32 detects the number of adhesive lines on the conveyor table 2 in real time. When the number of adhesive lines reaches the set value, the counting sensor 319 triggers a signal to start the drive motor 34 inside the motor box 33, automatically starting the cleaning process without manual intervention, ensuring continuous detection.

[0030] After the drive motor 34 starts, its output end drives the rotating disk 35 to rotate, and the rotating rod 36 at the eccentric part of the rotating disk 35 moves in a circular motion. The movable ring 38 on the outer surface of the rotating rod 36 cooperates with the rotating rod 36 through the limiting groove 39, and the limiting ring 37 at the end of the rotating rod 36 restricts the axial displacement of the movable ring 38, so that the movable ring 38 only performs reciprocating linear motion with the circular motion of the rotating rod 36. The guide rod 310 on one side of the movable ring 38 and the linkage rod 311 on the other side pass through the positioning seats 312 symmetrically arranged on both sides of the motor box 33, respectively. The positioning seats 312 provide stable guidance for the guide rod 310 and the linkage rod 311, ensuring that the movable ring 38 does not deviate during reciprocating motion.

[0031] The end of the linkage rod 311 furthest from the movable ring 38 is connected to the push rod 313. Under the constraint of the positioning seat 312, the push rod 313 reciprocates synchronously with the linkage rod 311, thereby driving the cleaning slide plate 314 at the end of the push rod 313 to slide along the limiting rod 315. The two ends of the limiting rod 315 are fixed to the inner surface of the fixing frame 31, ensuring that the cleaning slide plate 314 only makes stable horizontal movement and avoids shaking that affects the cleaning accuracy. The cleaning brush 316 at the inward end of the cleaning slide plate 314 moves with the cleaning slide plate 314 and slides back and forth on the lower surface of the detection camera 318 to remove dust, adhesive residue and other impurities attached to the camera surface, ensuring that the adhesive image captured by the camera is clear and unobstructed.

[0032] Once cleaning is complete, the drive motor 34 stops working, and all components reset under the linkage. The cleaning brush 316 detaches from the surface of the detection camera 318 without affecting its normal detection. Throughout the process, the two sets of symmetrical fixing frames 31 ensure that the intermittent component 3 cleans the detection camera 318 from all directions. The automatic triggering mechanism of the counting sensor 319 can flexibly control the cleaning frequency according to the amount of adhesive tape delivered, which avoids over-cleaning from affecting detection efficiency and can remove impurities in time. This improves the problem of blurred detection images caused by untimely manual cleaning in traditional methods and ensures the accuracy of adhesive tape detection.
