Description

Technical Field

[0001] This invention relates to the field of automotive painting technology, and more specifically to an automatic multi-angle painting device with a sliding rail. Background Technology

[0002] In existing automotive painting processes, automated painting equipment is widely used, mainly jointed robots and reciprocating sprayers. While jointed robots offer high flexibility and can perform fine painting on complex curved surfaces (such as door handles and bumpers), they are expensive to invest in, complex to program, have limited workspace, and are not optimal for painting large flat areas such as the car body. Reciprocating sprayers, while suitable for efficient painting of large flat areas, have a single motion trajectory and fixed spray gun posture, making them difficult to adapt to the undulations of the car body contour. This can easily lead to uneven coating along body edges and rounded transition areas, resulting in defects such as excessively thin or thick paint films, orange peel, and runs. Furthermore, traditional fixed painting systems cannot quickly adapt to the model and size of the vehicle being painted, requiring readjustment when changing models, severely impacting the flexibility of the production line. Therefore, there is an urgent need for a sliding rail automatic multi-angle painting device to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a sliding rail automatic multi-angle spraying device that is simple in structure, reasonable in design, and easy to use, thereby solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a track; two tracks are symmetrically arranged, and two movable seats are respectively rolled on the tracks on both sides; It also includes: The positioning frame is arranged in an inverted "U" shape. The bottom ends of the vertical rods on both sides of the positioning frame are fixedly connected to the movable seat. Positioning grooves are provided on both the front and rear sides of the positioning frame. The positioning seat comprises several units, and several rollers are symmetrically arranged on one side of each unit. The rollers are rotatably disposed in the positioning groove. The positioning component is disposed on the positioning seat and is engaged with the positioning groove in abutment. The electric measuring rod consists of several electric measuring rods, each of which is mounted on the bottom surface of the positioning base. The output end of the electric measuring rod is equipped with a laser rangefinder, which is electrically connected to the electric measuring rod. The guide belt is set inside the positioning frame by a tightening component, and the guide belt is movably connected to the electric measuring rod. The nozzle is mounted on the positioning frame using a movable component, and the movable component is in contact with the guide belt.

[0005] Using the above design scheme, a laser rangefinder is used to control the position of the bottom of the electric measuring rod, so that the bottom of several electric measuring rods is aligned with the distance between them and the car. Then, a tightening component is used to control the guide belt to be in a taut state, so that the trajectory of the guide belt is aligned with the contour of the car surface. Finally, a moving component is used to control the nozzle to move on the guide belt, ensuring that the paint is evenly sprayed on the car surface.

[0006] Furthermore, the positioning component includes: Two limiting rings are provided, and each is fixed to the inner wall of the positioning groove. The roller is located inside the limiting ring. The protrusions are of several kinds and are respectively fixed on the side wall of the positioning seat; The gears are multiple and are respectively set on the positioning seat. Motor 1 is fixed on the protrusion. The output end of motor 1 is fixedly connected to the gear. The gear is engaged with the tooth groove in the positioning groove.

[0007] Using the above design scheme, the motor controls the rotation of the gear, which in turn works with the toothed groove in the positioning groove to control the positioning seat to move along the direction of the positioning groove, moving the positioning seat to the corresponding position, so as to move the positioning seat to the inflection point of the car contour, ensuring that the trajectory of the guide belt is consistent with the car contour.

[0008] Furthermore, the tightening component includes: The limiting buckle consists of several buckles, each fixed to the end of the electric measuring rod, and the limiting buckle is inserted into the groove on the guide belt. Motor 2 is fixed on the inner right side of the positioning frame. The tightening shaft is screwed onto the inner right side of the positioning frame using a shaft seat. One end of the guide belt is fixedly connected to the tightening shaft. The positioning plate is fixed on the left inner wall of the positioning frame, and the left end of the guide belt is fixedly connected to the positioning plate.

[0009] By adopting the above design scheme, the rotation of the tightening shaft is controlled by motor 2, which makes it easy to control the length and tension of the guide belt.

[0010] Furthermore, the ends of several limit buckles are screwed with wheels using bearings. The wheels are set to roll in conjunction with the groove of the guide belt, which improves the rolling performance between the limit buckles and the guide belt and prevents the limit buckles from damaging the guide belt.

[0011] Furthermore, a positioning ring is fixed on the inner right side of the positioning frame, and the guide belt is movably inserted into the positioning ring to restrict the position of the guide belt and ensure that the guide belt is restricted to the limit buckle.

[0012] Furthermore, symmetrical tightening rings are fixed on the tightening shaft, and the guide belt is configured to abut against the tightening rings to restrict the retraction position of the guide belt.

[0013] Furthermore, the moving component includes: The movable rod is set on the annular wall of the nozzle. Adjusting rods are movably inserted at both ends of the movable rod. A spring is set on the adjusting rod. The two ends of the spring are fixedly connected to the movable rod and the adjusting rod. The nozzle is fixed in the middle of the movable rod. The connecting buckle consists of two buckles, each fixed to the end of the adjusting rod, and the end of the connecting buckle engages with the guide belt. A connecting rod is movably inserted into a groove in the middle of the positioning frame. The bottom end of the connecting rod is provided with a connecting component, which is connected to the annular wall of the nozzle. The guide screw is screwed to the top of the positioning frame using a shaft seat. The motor is fixed to the top of the positioning frame. The output end of the motor is connected to the end of the guide screw. The movable seat is screwed onto the guide screw. The connecting rod is inserted into the movable seat.

[0014] The above design scheme utilizes the rotation of the guide screw controlled by the motor to control the position of the movable seat, thereby driving the connecting rod to move synchronously, which in turn drives the moving rod and the nozzle to move along the guide belt.

[0015] Furthermore, the connection component includes: The connecting cylinder is a hollow cylindrical structure and is movably sleeved on the annular wall of the nozzle. Two fixing rings are symmetrically fixedly fitted onto the ring wall of the nozzle, and the connecting cylinder is located between the two fixing rings. Spring 2, wherein spring 2 is sleeved on the connecting rod, and both ends of spring 2 are respectively connected to the connecting rod and the movable seat; The connecting seat is fixed to the bottom end of the connecting rod and is screwed to the connecting cylinder by a rotating rod.

[0016] With the above design, the connecting cylinder can rotate freely at the bottom of the connecting seat, which makes it easy for the connecting cylinder and the nozzle to be perpendicular to the guide belt, thereby ensuring that the nozzle is perpendicular to the car surface and ensuring the uniformity of the spraying.

[0017] Furthermore, the bottom surface of the connecting seat is provided with a groove, and the nozzle is movably disposed in the groove to prevent the top of the nozzle from colliding with the connecting seat.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The automatic multi-angle spraying device of the present invention uses a laser rangefinder to control the position of the bottom end of the electric measuring rod, and then uses a tightening component to control the guide belt so that the trajectory of the guide belt is consistent with the contour of the car surface. Then, the moving component controls the spray head to move on the guide belt to ensure that the paint is evenly sprayed on the car surface. Attached Figure Description

The electric measuring rod 8 consists of several rods, each mounted on the bottom surface of the positioning base 5. The output end of the electric measuring rod 8 is equipped with a laser rangefinder 9, which is electrically connected to the electric measuring rod 8. The electric measuring rod 8 has the same structure and working principle as the existing electric telescopic rod. The electric measuring rod 8 controls the height position of the laser rangefinder 9, so that the bottom ends of the several electric measuring rods 8 are aligned with the distance between them and the surface of the car. A guide belt 10 is mounted within the positioning frame 3 using a tightening assembly 11. The guide belt 10 is movably connected to the electric measuring rod 8.

The limiting buckle 11-1 is inserted into the slot on the guide belt 10 to restrict the position of the guide belt 10. The points of the several limiting buckles 11-1 form the outline of the car surface. The ends of the several limiting buckles 11-1 are screwed to wheels 14 by bearings. The wheels 14 are rolled in cooperation with the groove of the guide belt 10 to improve the rolling performance between the limiting buckle 11-1 and the guide belt 10 and prevent the limiting buckle 11-1 from damaging the guide belt 10. Motor 2 11-2 is fixed on the right inner wall of the positioning frame 3. The tightening shaft 11-3 is screwed onto the right inner wall of the positioning frame 3 using a shaft seat. One end of the guide belt 10 is fixedly connected to the tightening shaft 11-3. Motor 2 11-2 controls the rotation direction of the tightening shaft 11-3, thereby controlling the tension of the guide belt 10. A positioning ring 15 is fixed on the right inner wall of the positioning frame 3. The guide belt 10 is movably inserted into the positioning ring 15 to limit the position of the guide belt 10 and ensure that the guide belt 10 is restricted on the limit buckle 11-1. Tightening rings 16 are symmetrically fixed on the tightening shaft 11-3. The guide belt 10 and the tightening ring 16 are set to cooperate and abut against each other to limit the retraction position of the guide belt 10. Positioning plate 11-4 is fixed on the left inner wall of positioning frame 3. The left end of guide belt 10 is fixedly connected to positioning plate 11-4, and positioning plate 11-4 fixes the starting position of guide belt 10.

Spring 13-3 is sleeved on the adjusting rod 13-2. Both ends of spring 13-3 are fixedly connected to the movable rod 13-1 and the adjusting rod 13-2. The nozzle 12 is fixed in the middle of the movable rod 13-1. The adjusting rod 13-2 moves in the end of the movable rod 13-1 in cooperation with spring 13-3 to avoid changing the distance between the two guide belts 10. The movable rod 13-1 is connected to the guide belt 10. Connecting buckle 13-4, there are two connecting buckles 13-4, and they are respectively fixed to the end of the adjusting rod 13-2. The end of the connecting buckle 13-4 is engaged with the guide belt 10 and moves in the groove of the guide belt 10. A connecting rod 13-5 is movably inserted into the groove in the middle of the positioning frame 3. A connecting assembly 13-6 is provided at the bottom end of the connecting rod 13-5. The connecting assembly 13-6 is connected to the annular wall of the nozzle 12. The connecting rod 13-5 controls the movement position of the moving rod 13-1. The connecting assembly 13-6 includes: The connecting cylinder 13-6-1 is a hollow cylindrical structure. The connecting cylinder 13-6-1 is movably sleeved on the annular wall of the nozzle 12, and the nozzle 12 can move freely up and down inside the connecting cylinder 13-6-1. Two fixing rings 13-6-2 are symmetrically fixedly fitted on the ring wall of the nozzle 12. The connecting cylinder 13-6-1 is located between the two fixing rings 13-6-2, restricting the position of the connecting cylinder 13-6-1. Spring 13-6-3 is sleeved on connecting rod 13-5. The two ends of spring 13-6-3 are connected to connecting rod 13-5 and movable seat 13-9 respectively. Utilizing the elastic force of spring 13-6-3, connecting cylinder 13-6-1 abuts against the corresponding fixing ring 13-6-2, thereby improving the stability between connecting cylinder 13-6-1 and nozzle 12. The connecting seat 13-6-4 is fixed to the bottom end of the connecting rod 13-5. The connecting seat 13-6-4 is screwed to the connecting cylinder 13-6-1 by a rotating rod. The connecting seat 13-6-4 plays a positioning role, so that the tilt angle of the connecting rod 13-5 changes according to the position of the guide belt 10. The bottom surface of the connecting seat 13-6-4 is provided with a groove 17, and the nozzle 12 is movably disposed in the groove 17 to prevent the top of the nozzle 12 from colliding with the connecting seat 13-6-4. Guide screw 13-7 is screwed to the top of positioning frame 3 via a bearing seat. Motor 3 13-8 is fixed to the top of positioning frame 3. The output end of motor 3 13-8 is connected to the end of guide screw 13-7. Movable seat 13-9 is threaded onto guide screw 13-7. Connecting rod 13-5 is inserted into movable seat 13-9. Motor 3 13-8 controls the rotation direction of guide screw 13-7, which facilitates the control of the movement direction of movable seat 13-9.

[0031] When using this invention, the positioning frame 3 is moved to a suitable position by the movable seat 2, so that the outer side of the car is located inside the positioning frame 3. According to the position of the curved surface of the car, the motor 7-4 is started. The motor 7-4 controls the gear 7-3 to rotate. The gear 7-3 drives the positioning seat 5 to move in the positioning groove 4, adjusting the electric measuring rod 8 to a suitable position. Then, the electric measuring rod 8 is started, and the electric measuring rod 8 drives the laser rangefinder 9 to descend. At the same time, the motor 11-2 controls the rotation of the tightening shaft 11-3, controlling the tension of the guide belt 10 to ensure that the guide belt 10 is placed within the limit buckle 11-1. With the action of the laser rangefinder 9, the bottom ends of several electric measuring rods 8 are aligned with the distance between them and the car surface. Then, the motor 7-4 is started. Motor 2 11-2 tightens the guide belt 10, making its trajectory consistent with the outline of the car body. Then, motor 3 13-8 is started, controlling the rotation of the guide screw 13-7. The guide screw 13-7 controls the position of the movable seat 13-9. The movable seat 13-9 drives the connecting rod 13-5 to move. The connecting rod 13-5 drives the connecting seat 13-6-4 to move synchronously. The connecting seat 13-6-4 drives the connecting cylinder 13-6-1 and the moving rod 13-1 to move. The moving rod 13-1 drives the adjusting rod 13-2 to move, so that the connecting buckle 13-4 is on the guide belt 10. This allows the spray nozzle 12 to move along the trajectory of the guide belt 10, ensuring the uniformity of the coating on the car surface.

[0032] Compared with the prior art, the beneficial effects of the present invention are: The laser rangefinder 9 is used to control the position of the bottom of the electric measuring rod 8 so that the bottom of several electric measuring rods 8 are aligned with the distance between them and the car. Then, the tightening component 11 is used to control the guide belt 10 to be in a taut state so that the trajectory of the guide belt 10 is aligned with the contour of the car surface. Finally, the moving component 13 is used to control the nozzle 12 to move on the guide belt 10 to ensure that the paint is evenly sprayed on the car surface. The positioning component 7 is set up, and the motor controls the rotation of the gear 7-3. In conjunction with the tooth groove in the positioning groove 4, the positioning seat 5 is controlled to move along the direction of the positioning groove 4, and the positioning seat 5 is moved to the corresponding position. This makes it easy to move the positioning seat 5 to the inflection point of the car contour, and ensure that the trajectory of the guide belt 10 is consistent with the car contour. The tightening component 11 is set up, and the tightening shaft 11-3 is rotated by the motor 11-2, which makes it easy to control the length of the guide belt 10 and the tension of the guide belt 10. The connecting component 13-6 is set up, and the connecting cylinder 13-6-1 rotates freely at the bottom end of the connecting seat 13-6-4, so that the connecting cylinder 13-6-1 and the nozzle 12 are perpendicular to the guide belt 10, thereby ensuring that the nozzle 12 is perpendicular to the car surface and ensuring the uniformity of spraying.
