Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology for windshields, specifically to an adhesive coating device for the windshields of sanitation vehicles. Background Technology

[0002] In the production and processing of sanitation vehicles, the windshield, as a crucial component, requires adhesive application to its edges before installation to achieve a sealing and securing effect. Current technology typically uses suction cups to position and fix the windshield, followed by adhesive application to its edges using a dispensing head.

[0003] Most existing glass fixing equipment uses suction cups in fixed positions. These suction cups cannot be flexibly adjusted according to the differences in glass size and shape during installation. When the glass specifications change, it is often necessary to replace the clamps or manually adjust the suction position. This not only increases the complexity of operation, but also easily leads to inaccurate positioning during the adjustment process. Inaccurate positioning will directly affect the accuracy of the glue dispensing trajectory, resulting in uneven glue application or glue line deviation.

[0004] However, since the suction cup position is not adjustable, the glass may experience uneven force when subjected to pressure, resulting in localized weak adhesion. This affects the stability of the glass during the dispensing process, easily leading to coating errors, increasing the defect rate, and reducing production efficiency. Utility Model Content

[0015] 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.

[0016] Please see Figure 1 An embodiment of this utility model provides an adhesive coating device for the windshield of a sanitation vehicle, including an operating table 11 and an adhesive dispensing head 12, with a positioning component 20 installed on the upper surface of the operating table 11.

[0017] like Figure 2 As shown, the positioning component 20 includes a mounting plate 21, which is set on the operating table 11 by a limiting member. Four sliding grooves 23 are symmetrically opened on the top of the mounting plate 21. A connecting block 24 is slidably connected inside the sliding groove 23, and a suction cup 22 is provided on the top of the connecting block 24.

[0018] According to the above technical solution, during use, the mounting plate 21 serves as the mounting base for the suction cup 22. It is mounted above the operating table 11 by limiting components to ensure overall stability. The top of the mounting plate 21 is provided with multiple symmetrical sliding grooves 23. The sliding grooves 23 and the connecting block 24 are slidably connected, allowing the connecting block 24 to move freely along the direction of the sliding grooves 23. When the connecting block 24 moves, the position of the suction cup 22 on its top also changes accordingly. Therefore, the operator can adjust the multiple suction cups 22 to the appropriate position according to the size of the windshield, thereby ensuring that the glass can be reliably adsorbed during the glue application process and meeting the positioning requirements of glass of different specifications.

[0019] like Figure 3 As shown, a drive assembly 30 is installed on one side of the mounting plate 21. The drive assembly 30 includes a motor 31. The output shaft of the motor 31 is fixedly connected to a lead screw 32. The lead screw 32 is located inside the mounting plate 21. Two threaded sleeves 33 are symmetrically threaded to the outside of the lead screw 32. A connector is provided on the outside of the threaded sleeves 33. The top of one end of the connector is hinged to the connecting block 24.

[0020] According to the above technical solution, during operation, the motor 31 in the drive assembly 30 is energized and drives the output shaft to rotate. Since the output shaft is fixedly connected to the lead screw 32, the lead screw 32 rotates synchronously. The lead screw 32 has a relatively symmetrical thread structure on its exterior, and two threaded sleeves 33 form a threaded pair with it. After the lead screw 32 rotates, the two threaded sleeves 33 move relative to each other along the direction of the lead screw 32. A connecting piece is fixed to the exterior of the threaded sleeve 33. When the threaded sleeve 33 moves, it drives the connecting piece to move together. The connecting piece is connected to the connecting block 24 through a hinge structure, thereby driving the connecting block 24 to move in the slide groove 23. Thus, the drive assembly 30 can realize the automatic adjustment of the positions of multiple suction cups 22, avoiding manual adjustment one by one, and greatly improving the adjustment efficiency and accuracy of the glass fixing point.

[0021] In one embodiment, the connector includes two first plates 34 and two second plates 35. The two first plates 34 are symmetrically fixed to the outside of the threaded sleeve 33. The outside of the first plates 34 is slidably connected to the inside of the second plates 35. The top of the second plates 35 is hinged to the bottom of the connecting block 24.

[0022] According to the above technical solution, when the threaded sleeve 33 moves under the drive of the lead screw 32, the first plate 34 fixed thereto also produces linear motion. The first plate 34 slides inside the second plate 35, so that its movement direction is guided and constrained, avoiding lateral deviation or shaking. The top of the second plate 35 is connected to the connecting block 24 through a hinge structure. When the first plate 34 moves, the second plate 35 drives the connecting block 24 to achieve stable linear displacement in the slide groove 23, so that the force transmitted from the drive component 30 to the connecting block 24 is more stable, avoiding jamming or error accumulation caused by direct rigid connection, thereby ensuring the smooth movement of the suction cup 22 and the reliability of positioning.

[0023] like Figure 4 As shown, specifically, the limiting component includes a limiting block 13 and a limiting groove 14. The limiting groove 14 is formed on the operating table 11, the limiting block 13 is slidably connected inside the limiting groove 14, and the top of the limiting block 13 is slidably connected to the bottom of the mounting plate 21.

[0024] According to the above technical solution, the mounting plate 21 needs to move to a certain extent as the connecting block 24 and the suction cup 22 are adjusted. The limiting block 13 and the limiting groove 14 are set to cooperate to prevent the movement trajectory of the mounting plate 21 from deviating. The limiting groove 14 is fixed on the operating table 11, and the limiting block 13 slides in the limiting groove 14, forming a stable guiding constraint. At the same time, the top of the limiting block 13 slides with the bottom of the mounting plate 21, so that the mounting plate 21 always maintains a stable linear movement state during the adjustment process, ensuring that the movement of the mounting plate 21 will not tilt or shake, ensuring the accuracy of the position adjustment of the suction cup 22 during the movement, thereby avoiding the glass from shifting during the positioning process.

[0025] In one embodiment, specifically, the lead screw 32 is configured as a bidirectional lead screw.

[0026] According to the above technical solution, when the lead screw 32 rotates, the threaded sleeves 33 located on both sides will move towards the center of the lead screw 32 or move apart to both sides at the same time. Through this symmetrical movement, the connector and the connecting block 24 can achieve synchronous symmetrical adjustment, thereby ensuring the coordination of multiple suction cups 22 during the movement process, so that the glass is subjected to balanced force during the positioning process, reducing the risk of glass breaking or shifting position due to uneven force during adsorption.

[0027] In one embodiment, the limiting block 13 is specifically constructed as a rectangular structure with ears.

[0028] According to the above technical solution, the limiting block 13 adopts a rectangular shape design, which enables it to slide stably in the limiting groove 14 and is not prone to rotation or shaking. At the same time, ear structures are added to both sides of the rectangular block. The ears can form an additional anti-dislodgement latch with the sides of the limiting groove 14. When the mounting plate 21 generates a large inertial force or is subjected to external impact during movement, the limiting block 13 will not easily fall out of the limiting groove 14, ensuring that the mounting plate 21 is always in a reliable guiding constraint and improving the sliding stability of the mounting plate 21.

[0029] In one embodiment, specifically, four grooves 23 are arranged diagonally along the mounting plate 21.

[0030] According to the above technical solution, since the slide 23 is arranged diagonally and the slide 23 itself is an oblique structure, when the drive component 30 drives the connecting block 24 to move along the slide 23, the four suction cups 22 will adjust their positions simultaneously along the oblique trajectory with the connecting block 24, so as to achieve balanced adsorption and stable fixation of the four corners of the windshield. The suction cups 22 can move inward or outward according to the size of the glass, adapting to different specifications of windshield glass, while avoiding the limitation that the suction cups can only adsorb at fixed points, so that the equipment can complete the positioning without changing the clamps when facing different sizes of glass.

[0031] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
