[0064] Through the above structural design, a gluing device in the automobile painting process is provided, which adopts a multi-point gluing unit to form a multi-point gluing structure. The glue liquid flows from all sides to the preset gluing position, which can better surround and cover the gluing positions such as the weld, making the thickness of the glue layer more uniform, solving the problem that a large amount of glue needs to be covered on the weld when a single glue outlet is used in order to completely seal the weld, and avoiding the phenomenon of excessive local glue dripping.

[0073] Embodiment 4:

[0074] like Figure 3-5 As shown, on the basis of the above-mentioned embodiment 3, a glue coating head support frame 18 is connected to the ring 17, and the top of the glue coating head support frame 18 is bent, and the glue coating head support frame 18 includes:

[0075] A limit slider 19, which is connected to the end of the horizontal section of the glue coating head support frame 18 through a spring, and a wedge-shaped surface is provided on the side of the limit slider 19;

[0076] An elastic member 20, the elastic member 20 is connected between the ends of the horizontal sections of adjacent glue coating head support frames 18;

[0077] A pressure regulating box 21, which is connected to the bottom end of the glue coating head support frame 18, and the bottom end of the pressure regulating box 21 is connected to the glue coating head 2;

[0078] A reinforcement groove 22, the reinforcement groove 22 is arranged on the vertical section of the glue coating support frame 18;

[0079] A reinforcement slip ring 23 is connected to the reinforcement grooves 22 of the plurality of glue-coated support frames 18 .

[0080] The working principle and beneficial effects of the above technical solution are:

[0081] The glue coating head support frame 18 is used to install the glue coating head 2. When in use, the limit slider 19 is installed on the ring 17, and the vertical section of the glue coating head support frame 18 extends downward and is connected to the voltage regulating box 21. The voltage regulating box 21 is connected to the glue coating head 2, and the glue coating head 2 is firmly installed on the glue coating head support frame 18; and multiple glue coating support frames 18 are reinforced at the same time by reinforcing the slip ring 23 to avoid deformation of the vertical section of the glue coating support frame 18. Elastic members are arranged between adjacent glue coating head support frames 18, and the damping of the elastic members 20 is equal, so that adjacent glue coating head support frames 18 maintain a preset spacing. During the movement and gluing process, the setting of the elastic member 20 helps to eliminate the unbalanced force state of the glue coating head support frame 18 and reduce the influence of inconsistent glue coating on the glue coating head support frame 18.

[0082] Embodiment 5:

[0083] On the basis of the above-mentioned embodiment 3, the angle between the glue coating head 2 and the pressure regulating box 21 is adjustable, and the plurality of glue coating heads 2 are all inclined toward the direction of the scraper plate 16 .

[0084] The working principle and beneficial effects of the above technical solution are:

[0085] The glue coating head 2 is rotatably connected to the bottom end of the pressure regulating box 21, and the inclination angle of the glue coating head 2 can be adjusted by electronic control. The glue coating head 2 is adjusted to be inclined toward the scraper plate 16, so that the glue discharge direction of multiple glue coating heads 2 can be toward the center of the glue gun, so that part of the outflowing glue flows outward to cover the weld and other structures that need to be sealed, and the other part can flow better toward the center. The glue confluence is scraped flat by moving the scraper plate 16, thereby ensuring that the glue coating thickness at each position is uniform and better covering the preset gluing position.

[0086] Embodiment 6:

[0087] like Figure 3-5 As shown, on the basis of the above-mentioned embodiment 1, an annular groove 24 is opened on the outer side of the ring 17, and the limiting slider 19 is slidably set in the annular groove 24. A support plate 25 is connected to the center of the ring 17, and the support plate 25 passes through the cylinder 14, and a vertical groove 26 for the support plate 25 to slide is opened on the side of the cylinder 14.

[0088] A motor is connected inside the upper seat body 13 , and a screw rod 27 is connected to the output end of the motor. The screw rod 27 is rotatably connected to the bottom wall of the cylinder 14 , and the screw rod 27 passes through a threaded hole in the center of the support plate 25 .

[0089] The working principle and beneficial effects of the above technical solution are:

[0090] An annular chute 24 is provided on the ring 17, and the annular chute 24 is set in the form of a T-slot. The end of the glue head support frame 18 is slidably set in the annular chute 24, and the limit sliders 19 on the upper and lower sides are clamped in the annular chute 24 to limit the glue head support frame 18. A distance sensor is provided on the multi-point gluing unit to detect the distance between the glue head 2 and the gluing position in real time, thereby more accurately reflecting the structural dimensions of the weld and the like. When the thickness of the weld is large, the starting motor drives the screw 27 to rotate forward, and the screw 27 and the threaded hole in the center of the support plate 25 are threadedly transmitted, driving the support plate 25 to move upward, and the ring 17 also moves upward accordingly, and the vertical chute 26 guides the support plate 25, thereby driving the glue head 2 to move upward. When the thickness of the weld is small, the starting motor drives the screw 27 to rotate in the opposite direction, and the screw 27 and the threaded hole in the center of the support plate 25 are threadedly transmitted, driving the support plate 25 to move downward, and the ring 17 also moves downward accordingly, thereby driving the glue head 2 to move downward.

[0091] Through the above-mentioned structural design, after the gluing robot adjusts the height of the gluing head according to the preset gluing path, the vertical position of the gluing head 2 is precisely adjusted for the second time according to the real-time detection results of the distance sensor, so that it can better adapt to the gluing positions such as welds, avoid the problem of uneven glue thickness caused by inconsistent weld thickness, improve the gluing effect of the car body, and the adjustment method is simple and easy to control.

[0092] Embodiment 7:

[0093] like Figure 4 , 5 As shown, based on the above-mentioned embodiment 6, the voltage regulating box 21 includes:

[0094] A slide rail 31, the slide rail 31 is connected to the bottom end of the inner wall of the voltage regulating box 21, and the two slide rails 31 are symmetrically arranged;

[0095] A movable block 32, the movable block 32 is slidably connected to the slide rail 31, and a spring is connected between the movable block 32 and the side wall of the voltage regulating box 21;

[0096] A booster clamp 33, which is connected to one side of the movable block 32 close to the center of the voltage regulating box 21;

[0097] The adapter frame 34 is connected to the side wall of the voltage regulating box 21, and the adapter frame 34 is bent;

[0098] A movable pressure rod 35 is provided with a movable pressure rod slide 35 on the movable pressure rod 35, and the movable pressure rod slide 35 is slidably connected to the top of the adapter frame 34;

[0099] The connecting rod 36 is hinged on the adapter frame 34 in the middle, and a waist-shaped hole is provided at the hinge. The bottom end of the connecting rod 36 is hinged to the movable block 32 , and the top end of the connecting rod 36 is hinged to an end of the movable pressure rod 35 away from the center of the voltage regulating box 21 .

[0100] The top of the glue coating head 2 is connected with a pressurizing bag 37 , which is located inside the pressure regulating box 21 and arranged between the two pressurizing jaws 33 . When the pressurizing jaws 33 squeeze the pressurizing bag 37 , the glue coating amount of the glue coating head 2 increases.

[0101] A transmission rod 38 is slidably connected to the inner side wall of the pressure regulating box 21. A wedge surface 39 is provided at one end of the transmission rod 38 located inside the pressure regulating box 21, and the movable pressure rod 35 is slidably provided on the wedge surface 39; the other end of the transmission rod 38 is connected to a sliding ball 40, and the sliding ball 40 slides relative to the side wall of the conical cylinder 15.

[0102] The working principle and beneficial effects of the above technical solution are:

[0103] When the pressure regulating box 21 is in use, as the glue coating head support frame 18 moves upward, the sliding ball 40 is driven to slide upward along the side wall of the conical cylinder 16, and the diameter of the conical cylinder 16 gradually increases from bottom to top, pushing the transmission rod 38 into the inside of the pressure regulating box 21, and the wedge surface 39 of the transmission rod 38 slides relative to the movable pressure rod 35, squeezing the movable pressure rod 35 to move in the direction away from the center of the pressure regulating box 21, and the adapter frame 34 guides the movable pressure rod 35, and the movable pressure rod 35 drives the connecting rod 36 to rotate, and the other end of the connecting rod 36 drives the movable block 32 to slide on the slide rail 31 and approach the center of the pressure regulating box 21, driving the booster clamp 33 to squeeze the booster bag 37, increasing its pressure, so that the glue coating amount of the glue coating head 2 is increased, and a larger glue coating amount can adapt to a thicker weld, so that the glue liquid fully covers the area to be welded. As the glue coating head support frame 18 moves downward, the sliding ball 40 is driven to slide downward along the side wall of the conical cylinder 16, and the movable block 32 is reset to the outside under the action of the spring, driving the connecting rod 36 to rotate, so that the movable pressure rod 35 keeps the trend of approaching the center of the pressure regulating box 21, so that the movable pressure rod 35 is always pressed on the wedge surface 39, and the other end of the transmission rod 38 is always pressed against the surface of the conical cylinder 16. At this time, the squeezing force of the boosting jaw 33 on the boosting bag 37 is reduced, reducing its boosting capacity, so that the amount of glue coated by the glue coating head 2 is reduced, and a smaller amount of glue can adapt to a thinner weld thickness, while avoiding glue waste and glue dripping.

[0104] Through the above-mentioned structural design, while adjusting the height of the glue coating head 2, the adaptive adjustment of the glue coating amount is effectively achieved, so that the glue coating amount can adapt to welds of different thicknesses, ensuring that the glue repeatedly covers the welds and other gluing areas, and in areas with smaller thickness, the glue coating amount is adjusted to be less, thereby reducing glue waste and avoiding excessive dripping of glue, making the glue coating thickness approach consistent, and providing better protection for the vehicle body structure.

[0105] Embodiment 8:

[0107] The working principle and beneficial effects of the above technical solution are:

[0108] The scraper plate 16 is hollow. During the gluing operation, the guide fan 41 is started to rotate, and the air flow is sucked into the conical cylinder 15 from the air inlet 43, and then flows out through the air outlet 42. The side wall of the conical cylinder 15 is arranged inclined, so that the air flow flows obliquely downward to the surface of the glue liquid, thereby accelerating the curing speed of the glue liquid.

[0109] Embodiment 9:

The cooling liquid is passed into the cooling pipeline 46. The cooling pipeline 46 is arranged on the inner side of the air outlet 42, so that the airflow is preferentially contacted with the cooling pipeline 46 when it flows out, thereby reducing the temperature of the airflow. The formed low-temperature airflow flows to the glue liquid, thereby accelerating the curing speed of the glue liquid. An electromagnetic sheet 48 is provided on the inner wall of the conical cylinder 15. When the height of the glue coating head 2 is high, the glue coating amount is large, and the electromagnetic sheet 48 is in a non-powered state. Under the elastic force of the spring sheet 47, the adjacent support sleeves 45 are separated from each other, and the cooling pipelines 46 of adjacent layers are at a long distance, so that the cooling pipeline 46 is distributed in the conical cylinder 15 with a large span. , ensuring a large-scale cooling effect on the airflow, providing sufficient cooling air volume, and ensuring the cooling and curing speed under the condition of large glue quantity; when the height of the glue coating head 2 is relatively low, the glue coating quantity is small, and the electromagnetic sheet 48 is energized to generate attraction to the magnetic block 49, and the lowest support sleeve 45 remains fixed. Under the action of magnetic attraction, the spring sheet 47 is driven to deform, so that the adjacent support sleeves 45 are close to each other and move toward the lowest support sleeve 45. The cooling pipelines 46 of adjacent layers are at a closer distance, so that the cooling pipelines 46 are distributed in a small span at the lower part of the inner wall of the conical cylinder 15, thereby improving the cooling effect on the lower airflow, and in the case of small glue quantity, the cooling of the airflow is more concentrated, reducing the loss of cooling airflow, and playing a role in energy saving.
