Description

Technical Field

[0001] This utility model relates to the field of glue path detection technology for dispensing machines, specifically a glue path detection device for dispensing machines. Background Technology

[0002] Dispensing machine adhesive path detection is mainly used to monitor parameters such as the continuity, positional accuracy, and consistency of adhesive amount during the dispensing process in real time. This ensures product quality and production efficiency, thereby reducing production costs, decreasing scrap rates, improving the reliability and stability of the production process, and enhancing the company's competitiveness in the market. Through precise detection and control of the adhesive path, automated production can also be achieved, reducing manual intervention and improving production efficiency. At the same time, it provides a strong guarantee for the high quality and consistency of products, helping companies establish a good brand image and meet the ever-increasing market demands and customer requirements.

[0003] When inspecting the glue path of a dispensing machine, a 3D laser profile measuring instrument (SR8020) is often used. The 3D laser profile measuring instrument is installed next to or above the dispensing head to allow close-up imaging of the glue path during the dispensing process. However, in actual use, to ensure the stability of the 3D laser profile measuring instrument during operation and to guarantee inspection accuracy, its installation structure may adopt a relatively complex and tight connection and fixing method, using multiple bolts and nuts for fastening, or using semi-permanent fixing methods such as glue or welding. These methods require a lot of time and effort to disassemble and reinstall when the position needs to be adjusted, which is cumbersome. Therefore, we propose a glue path inspection device for dispensing machines. Utility Model Content

[0004] The purpose of this invention is to provide a glue path detection device for a dispensing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue path detection device for a dispensing machine, comprising a glue container and a three-dimensional laser profile measuring instrument. The surface of the glue container is connected to a dispensing head. A detection head is mounted on the surface of the three-dimensional laser profile measuring instrument. Several connecting slots are mounted on the surface of the three-dimensional laser profile measuring instrument. A limiting structure is provided on the surface of the glue container. The limiting structure includes a limiting ring, which is fixedly connected to the arc surface of the glue container. A threaded rod is rotatably connected to the arc surface of the limiting ring. A driving block is threadedly connected to the surface of the threaded rod. A support arm is fixedly connected to the surface of the driving block. A rotating shaft is rotatably connected to the surface of the support arm. The end of the rotating shaft away from the support arm is fixedly connected to the three-dimensional laser profile measuring instrument. A circular ring is fixedly connected to the side of the three-dimensional laser profile measuring instrument closest to the support arm. Several circular holes are formed on the surface of the circular ring. A pin slides through the surface of the support arm, and the pin's size is adapted to the circular holes.

[0006] The effects achieved by the above components are as follows: by setting the limiting structure, the three-dimensional laser profile measuring instrument can be conveniently installed and its position adjusted, which greatly saves installation and adjustment time, improves work efficiency, and comprehensively enhances the practicality and functionality of the glue path detection device for dispensing machines.

[0008] The effect achieved by the above components is that the pressure plate increases the damping force when the ring rotates, thereby preventing the ring from being too smooth and requiring repeated adjustments due to excessive rotation.

[0009] Preferably, one end of the pin is fixedly connected to an elastic rope, and the other end of the elastic rope is fixedly connected to the support arm.

[0010] The effect achieved by the above components is that the elastic rope reaches the position of the pin, preventing the pin from falling out of the support arm and being lost due to shaking.

[0012] The effect achieved by the above components is that the rotation of the turntable will drive the threaded rod to rotate, and the turntable facilitates the rotation of the threaded rod.

[0013] Preferably, a guide rod slides through the surface of the drive block, and the guide rod is fixedly connected to the arc surface of the limiting ring.

[0014] The effect achieved by the above components is that the drive block slides along the arc surface of the guide rod, and the guide rod restricts the movement path of the drive block, thereby preventing the drive block from rotating during movement.

[0015] Preferably, two U-shaped plates are fixedly connected to one side of the three-dimensional laser contour measuring instrument, and two elastic pieces are fixedly connected to the inner wall of the U-shaped plates. The elastic pieces are copper sheets with elasticity.

[0016] The effect achieved by the above components is to limit the transmission line within the U-shaped plate using spring clips, thereby preventing the arbitrary placement of the transmission line from affecting the function of adjusting the three-dimensional laser profile measuring instrument.

[0025] 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.

[0026] Please see Figure 1-2 This utility model provides a technical solution: a glue path detection device for a dispensing machine, including a glue tank 1 and a three-dimensional laser profile measuring instrument 3. A dispensing head 2 is connected to the surface of the glue tank 1. A detection head 4 is mounted on the surface of the three-dimensional laser profile measuring instrument 3. Several connecting slots 5 are mounted on the surface of the three-dimensional laser profile measuring instrument 3. A limiting structure 6 is provided on the surface of the glue tank 1. The limiting structure 6 includes a limiting ring 601, which is fixedly connected to the arc surface of the glue tank 1. A threaded rod 602 is rotatably connected to the arc surface of the limiting ring 601. A driving block 603 is threadedly connected to the surface of the threaded rod 602. A support arm 604 is fixedly connected to the surface of the driving block 603. A rotating shaft 605 is rotatably connected to the surface of the arm 604. The end of the rotating shaft 605 away from the support arm 604 is fixedly connected to the three-dimensional laser profile measuring instrument 3. A ring 606 is fixedly connected to the side of the three-dimensional laser profile measuring instrument 3 near the support arm 604. Several circular holes 607 are opened on the surface of the ring 606. A pin 608 slides through the surface of the support arm 604. The size of the pin 608 matches that of the circular holes 607. By setting the limiting structure 6, the three-dimensional laser profile measuring instrument 3 can be conveniently installed and its position adjusted, which greatly saves installation and adjustment time, improves work efficiency, and comprehensively enhances the practicality and functionality of the dispensing machine glue path detection device.

[0027] Reference Figure 3 and Figure 4 and Figure 5As shown in this embodiment: an extension plate 609 is fixedly connected to the surface of the support arm 604. A round rod 610 slides through the surface of the extension plate 609. A spring 611 is fitted onto the arc surface of the round rod 610. The two ends of the spring 611 are fixedly connected to the round rod 610 and the extension plate 609, respectively. A pressure plate 612 is fixedly connected to the end of the round rod 610 near the ring 606. The pressure plate 612 fits against the arc surface of the ring 606. The pressure plate 612 increases the damping force when the ring 606 rotates, thereby preventing excessive rotation due to excessive smoothness and the need for repeated adjustments. One end of the pin 608 is fixedly connected to an elastic rope 613. The other end of the elastic rope 613 is fixedly connected to the support arm 604. The elastic rope 613 restricts the position of the pin 608, preventing the pin 608 from falling out of the support arm 604 due to shaking and being lost. A turntable 614 is fixedly connected to the end of the threaded rod 602 away from the limiting ring 601. The vertical cross-section of the turntable 614 is cross-shaped. Rotation of the turntable 614 will drive the threaded rod 602 to rotate, thus facilitating the rotation of the threaded rod 602. A guide rod 615 slides through the surface of the drive block 603. The guide rod 615 is fixedly connected to the arc surface of the limiting ring 601. When the drive block 603 moves, it slides along the arc surface of the guide rod 615, thus limiting the movement path of the drive block 603 and preventing the drive block 603 from rotating during movement. Two U-shaped plates 616 are fixedly connected to one side of the three-dimensional laser profile measuring instrument 3. Two spring pieces 617 are fixedly connected to the inner wall of the U-shaped plates 616. The spring pieces 617 are elastic copper sheets that limit the transmission line within the U-shaped plates 616, thereby preventing the transmission line from being placed arbitrarily and affecting the adjustment of the three-dimensional laser profile measuring instrument 3.

[0028] Working principle: When the 3D laser profile measuring instrument 3 installed on one side of the dispensing head 2 needs to be used, the position of the 3D laser profile measuring instrument 3 needs to be adjusted first. Rotating the turntable 614 will drive the threaded rod 602 to rotate. The rotation of the threaded rod 602 will rotate on the arc surface of the limiting ring 601. The rotation of the threaded rod 602 will drive the drive block 603 to move away from the glue can 1 through the thread. The drive block 603 will slide along the arc surface of the guide rod 615. The guide rod 615 will limit the movement path of the drive block 603, thereby preventing the drive block 603 from rotating during movement. The movement of the drive block 603 will cause the support arm 604 to move, which in turn will cause the rotating shaft 605 to move. The movement of the rotating shaft 605 will then cause the 3D laser profile measuring instrument 3 to move. When the 3D laser profile measuring instrument 3 moves to a suitable distance from the dispensing head 2, the angle of the 3D laser profile measuring instrument 3 needs to be adjusted. First, pull the pin 608. The pin 608 will slide inside the support arm 604 and gradually disengage from the round hole 607. The movement of the pin 608 will pull the elastic rope 613. After the pin 608 disengages from the round hole 607, rotate the 3D laser profile measuring instrument 3. The 3D laser profile measuring instrument 3 drives the ring 606 to rotate. As the ring 606 rotates, the rod 610, with the help of the spring 611, causes the pressure plate 612 to press against the arc surface of the ring 606. The pressure plate 612 increases the damping force when the ring 606 rotates, thus preventing excessive rotation and the need for repeated adjustments. When the 3D laser profile measuring instrument 3 rotates to a suitable angle, the pin 608 is pressed, and the pin 608 inserts into the circular hole 607, thereby limiting the angle of the 3D laser profile measuring instrument 3. The elastic rope 613 further limits the pin 608. The position is designed to prevent the pin 608 from coming loose from the support arm 604 due to shaking and being lost. Then, the transmission line is inserted into the connecting slot 5 on the surface of the 3D laser profile measuring instrument 3. At this time, the transmission line is pressed into the U-shaped plate 616 in sequence. The transmission line will squeeze the spring piece 617 inside the U-shaped plate 616. The spring piece 617 will be compressed when squeezed. At this time, the transmission line will slide into the bottom of the inner wall of the U-shaped plate 616. When the spring piece 617 rebounds, it will squeeze the transmission line with its own elasticity, thereby limiting the transmission line within the U-shaped plate 616, thus preventing the transmission line from being placed randomly and affecting the adjustment of the 3D laser profile measuring instrument 3.
