Description

Technical Field

[0001] This application relates to the field of automotive sunroof production equipment technology, and in particular to an adhesive injection device for automotive sunroof production. Background Technology

[0002] In the production process of automotive sunroofs, the glue injection process plays a crucial role, directly affecting the sunroof's sealing performance and structural stability. However, most of the glue injection devices widely used in the industry currently employ a needle valve for injection. While the needle valve can minimize glue leakage and dripping, glue residue inevitably remains on the outer wall of the injection syringe after each injection, and the syringe head may become clogged due to glue solidification.

[0003] These residual adhesive residues can contaminate the sunroof body to be processed later, leading to a lower product yield and increasing the frequency and intensity of manual cleaning. Furthermore, if the cured adhesive is not cleaned up in time, it will severely affect the accuracy and amount of adhesive applied in subsequent processes, thereby compromising the sunroof's sealing performance and failing to meet the high-quality production requirements of automotive sunroofs. Utility Model Content

[0004] In order to improve the cleanliness of the glue injection device in the production process of automotive sunroofs, this application provides a glue injection device for automotive sunroof production.

[0005] This application provides a glue injection device for automobile sunroof production, which adopts the following technical solution: An adhesive injection device for automotive sunroof production includes a housing, a positioning component for positioning the sunroof, an adhesive injection component, and a cleaning component for cleaning the adhesive injection syringe. The cleaning component includes a mounting box mounted on the housing, a rotating rod rotatably mounted on the mounting box, a second motor for controlling the rotation of the rotating rod, and a cleaning head mounted on the rotating rod.

[0006] By adopting the above technical solution, the positioning component can quickly position the sunroof body, ensuring accurate glue injection later. After the glue injection component completes the glue injection operation, the cleaning component can automatically clean the glue injection syringe. The second motor drives the rotating rod to rotate the cleaning head, which can efficiently remove residual glue from the glue injection syringe, reduce manual operation, and effectively improve the overall cleanliness and operational efficiency of the device.

[0007] In one specific implementation, a movable plate is slidably mounted on the cleaning head, a first spring is mounted on the movable plate, the end of the first spring away from the movable plate is connected to the cleaning head, and a cleaning sponge is mounted on the movable plate.

[0008] By adopting the above technical solution, when the dispensing syringe is inserted into the cleaning head, it squeezes the movable plate and compresses the first spring. The elastic force generated by the first spring allows the cleaning sponge to fit tightly against the dispensing syringe head. Combined with the rotation of the cleaning head, this significantly improves the cleaning effect of the syringe head and prevents adhesive residue from hardening.

[0009] In one specific implementation, a baffle is installed on the mounting box, and a brush is installed on the baffle.

[0010] By adopting the above technical solution, the brush on the baffle can perform preliminary cleaning of the outer wall of the syringe during the process of the dispensing syringe entering or exiting the cleaning head, thereby further improving the cleaning efficiency.

[0011] In one specific implementation, the brush is tilted, with the end of the brush away from the baffle lower than the end of the brush connected to the baffle.

[0012] By adopting the above technical solution, the downward-sloping brush can guide the residual glue downward and remove it from the syringe when cleaning the outer wall of the syringe, preventing the glue from being carried to other parts of the syringe by the brush and causing secondary pollution, thus ensuring thorough cleaning.

[0013] In one specific implementation scheme, a guide rod is installed on the mounting box, a movable block is slidably installed on the guide rod, a second spring is sleeved on the guide rod, one end of the second spring is connected to the movable block, and the other end is connected to the mounting box, the movable block is connected to the baffle, and the baffle has a guide groove.

[0014] By adopting the above technical solution, the guide groove can guide the insertion direction of the dispensing syringe, ensuring that the syringe accurately enters the cleaning head. When there are differences in syringe diameter, the movable block can slide along the guide rod, and the second spring provides elastic adjustment force, driving the baffle to adaptively adjust its position, ensuring that the brush is always in contact with the outer wall of the syringe, and improving the device's adaptability to syringes of different specifications.

[0015] In one specific implementation, the positioning component includes a fixing plate mounted on the chassis, and a support column is mounted on the fixing plate.

[0016] By adopting the above technical solution, the skylight is placed on the support column, which is then inserted into the positioning hole of the skylight. This allows for quick skylight positioning without complicated adjustment steps, improving positioning efficiency and accuracy and laying the foundation for precise glue injection later.

[0017] In one specific implementation, the dispensing assembly includes a mounting bracket mounted on the machine. A guide rail is mounted on the mounting bracket, and a slider is slidably mounted on the guide rail. A screw is rotatably mounted on the mounting bracket, and the slider is threadedly connected to the screw. A first motor for controlling the rotation of the screw is mounted on the machine housing. A support rod is mounted on the slider, and a first cylinder is mounted on the support rod. The output shaft of the first cylinder is connected to a first injection valve for dispensing the adhesive.

[0018] By adopting the above technical solution, the first motor drives the screw to rotate, which in turn drives the slider to slide along the guide rail, thereby adjusting the horizontal position of the frame rod and the first impact valve; the first cylinder controls the up and down movement of the first impact valve, achieving precise docking between the glue injection syringe and the window body. This structure allows for flexible adjustment of the glue injection position to meet the glue injection needs of different specifications of skylights, improving the versatility of the device.

[0019] In one specific implementation, a detection assembly is mounted on the chassis, the detection assembly including an industrial robot mounted on the chassis, the industrial robot being connected to a vision sensor and a second impact valve.

[0020] By adopting the above technical solution, after the glue is injected, the industrial robot moves the vision sensor to the glue injection position, collects glue line image information and judges whether the glue injection amount meets the standard. If the glue injection amount is insufficient, the industrial robot can quickly adjust the position of the second impact valve to add glue, ensuring that the glue injection quality meets the standard and reducing product rework caused by insufficient glue injection amount.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Significantly improved cleanliness, ensuring product quality: This application achieves automated cleaning of the glue injection syringe through a cleaning component. The brush first performs preliminary cleaning of the outer wall of the syringe, and then the cleaning head rotates and fits tightly with the cleaning sponge to thoroughly remove residual glue from the syringe head, preventing glue from hardening and clogging or contaminating the window, greatly reducing the product defect rate caused by glue residue, and ensuring the sealing performance and structural stability of the car sunroof.

[0022] 2. High degree of automation, reducing labor costs: The positioning component uses support columns to cooperate with the window positioning holes to achieve rapid window positioning; the glue injection component uses a first motor, screw, and first cylinder to automatically adjust the glue injection position and height; the detection component uses a vision sensor to automatically detect the glue injection amount, and the second impact valve automatically replenishes the glue; the cleaning component automatically cleans the syringe. The fully automated operation reduces manual intervention, lowers the labor intensity of manual positioning, detection, and cleaning, avoids human error, and improves production efficiency.

[0033] This application discloses a glue injection device for automobile sunroof production, referring to... Figure 1 and Figure 2 It includes a chassis 1, a positioning component 2 for positioning the window and a glue injection component 3 for injecting glue into the window, and a detection component 4 for detecting the glue injection status.

[0034] The positioning component 2 includes a fixing plate 21, which is fixedly installed on the chassis 1. A support column 22 is fixedly installed on the fixing plate 21, and the support column 22 is vertically arranged.

[0035] In this embodiment, the window has a built-in positioning hole. By placing the window on the support column 22 and inserting the support column 22 into the positioning hole on the window, the window can be quickly positioned.

It is mainly used for precise dispensing of medium and low viscosity fluids in the field of industrial automation. This embodiment will not describe the structural composition of the ejector valve.

[0037] After the window is positioned, the first motor 36 controls the screw 35 to rotate, and the screw 35 drives the slider 33 to slide on the guide rail 32, thereby causing the support rod 37 to move and adjust the position of the first impact valve 39. The first cylinder 38 controls the first impact valve 39 to descend and get close to the window to realize the glue injection of the window.

[0038] The detection component 4 includes an industrial robot 41, which is fixedly mounted on the chassis 1. In this embodiment, the industrial robot 41 is also a prior art device. A vision sensor 42 and a second impact valve 43 are fixedly mounted on the industrial robot 41.

[0039] After the first impact valve 39 completes the glue injection, the industrial robot 41 controls the vision sensor 42 and the second impact valve 43 to move. The vision sensor 42 collects information to determine whether the glue injection amount has been reached. If the glue injection amount has not been reached, the second impact valve 43 will add glue to ensure that the glue injection amount meets the glue injection standard.

[0040] Reference Figure 2 , Figure 3 and Figure 4The chassis 1 is equipped with a cleaning assembly 5 for cleaning the dispensing needles of the first impact valve 39 and the second impact valve 43.

In this embodiment, a threaded hole is provided at the end of the rotating rod 52. A threaded rod is installed at the end of the cleaning head 54 that is connected to the rotating rod 52. The cleaning head 54 is tightened onto the rotating rod 52 through the threaded rod. Since the threaded connection method is also a common connection method, the structure is simple and does not affect the understanding of the solution of this application. The connection method between the rotating rod 52 and the cleaning head 54 is not shown in detail in the accompanying drawings of the specification.

[0041] Reference Figure 4 and Figure 5 A movable plate 541 is slidably installed inside the cleaning head 54. A first spring 542 is fixedly installed on the movable plate 541. The end of the first spring 542 away from the movable plate 541 is fixedly connected to the cleaning head 54. A cleaning sponge 543 is fixedly installed on the movable plate 541.

[0042] Reference Figure 6 , Figure 7 and Figure 8 A guide rod 561 is fixedly installed on the mounting box 51. A movable block 562 is slidably installed on the guide rod 561. A second spring 563 is sleeved on the guide rod 561. One end of the second spring 563 is fixedly connected to the movable block 562, and the other end is fixedly connected to the mounting box 51. A baffle 564 is fixedly installed on the movable block 562. In this embodiment, two baffles 564 are provided. The two baffles 564 are installed in an installation manner and are arranged opposite each other, with a distance between them. Guide grooves 566 are opened on the vertical sides of the two baffles 564 that are close to each other. When the two baffles 564 are joined together, the guide grooves 566 form a cone shape. A brush 565 is fixedly installed on the vertical sides of the two baffles 564 that are close to each other. The end of the brush 565 away from the baffle 564 is inclined downward.

[0043] After each window's glue injection operation is completed, the first cylinder 38 controls the first needle valve 39 and the industrial robot 41 controls the second needle valve 43 to be inserted into the cleaning head 54 respectively. When the first needle valve 39 and the second needle valve 43 pass through the brush 565, the brush 565 will clean the cylinder wall of the glue injection syringe of the first needle valve 39 and the second needle valve 43. The first needle valve 39 and the second needle valve 43 will press against the cleaning sponge 543 and press the movable plate 541 and the first spring 542, so that the cleaning sponge 543 can be tightly attached to the head of the glue injection syringe of the first needle valve 39 and the second needle valve 43. Then the second motor 53 controls the cleaning head 54 to rotate, completing the cleaning of the head of the glue injection syringe.

[0044] The implementation principle of this application embodiment is as follows: When performing glue injection on the sunroof window of an automobile, the window is first quickly positioned by the positioning component 2 to ensure accurate glue injection position; then the glue injection component 3 is started, and the horizontal position of the first impact valve 39 is adjusted by the first motor 36, screw 35, slider 33 and other structures, and then the first cylinder 38 controls its up and down movement to achieve precise docking with the window and complete the glue injection; after the glue injection is completed, the vision sensor 42 in the detection component 4 detects the amount of glue injected. If the amount of glue injected is insufficient, the second impact valve 43 will add glue; after each glue injection operation, the cleaning component 5 will clean the glue injection syringes of the first impact valve 39 and the second impact valve 43. First, the outer wall of the syringe is cleaned by the brush 565, and then the head of the syringe is cleaned by the rotation of the cleaning head 54 and the contact of the cleaning sponge 543, which effectively ensures the cleanliness of the glue injection syringe and improves the overall operation quality and efficiency of the device.
