Especially in the painting industry, traditional manual spraying methods have gradually been replaced by automated spraying equipment. As a core component of modern spraying production lines, automatic spray gun spraying mechanisms are crucial for achieving precise control of spraying thickness, improving paint utilization, reducing environmental pollution, and enhancing operation safety.

[0003] Early automatic spraying systems often had single functions, complex operations, and limitations in precisely controlling spraying distance and uniformity. To meet the market demand for high-efficiency and high-precision spraying, spraying technologies have continuously advanced, and integrated and intelligent spraying equipment has emerged.

The spray gun assembly 3 is detachably connected to one end of the transverse movement assembly 2, and the spraying direction of the spray gun assembly 3 faces the workpiece on the spraying station. The lifting assembly 1 can simultaneously drive the transverse movement assembly 2 and the spray gun assembly 3 to vertically lift. The transverse movement assembly 2 can drive the spray gun assembly 3 to horizontally move in a direction approaching or away from the workpiece, so as to change the distance between the spray gun assembly 3 and the workpiece. By setting the lifting assembly 1, the transverse movement assembly 2 and the spray gun assembly 3, the lifting assembly 1 can simultaneously drive the transverse movement assembly 2 and the spray gun assembly 3 to vertically lift, thereby changing the vertical distance between the spray gun assembly 3 and the workpiece. The transverse movement assembly 2 can drive the spray gun assembly 3 to horizontally move, thereby changing the horizontal distance between the spray gun assembly 3 and the workpiece, further realizing the automation of the mechanism, making the workpiece sprayed by the spray gun assembly 3 more uniform and having a higher qualification rate. Moreover, through the coordinated operation of the lifting assembly 1, the transverse movement assembly 2 and the spray gun assembly 3, automatic spraying is realized, enabling the spray gun assembly 3 to achieve precise positioning in three-dimensional space, which greatly enhances the adaptability of the equipment to workpieces of different sizes and shapes. Whether it is a large flat workpiece or a complex structural part, the best spraying distance can be achieved by adjusting the height and horizontal position of the spray gun, ensuring that the coating is uniform and there are no omissions. And this spraying mechanism reduces the dependence on manual operation, greatly reduces the labor intensity and operation risk. Especially when dealing with toxic or volatile coatings, it effectively protects the safety and health of operators, improves work efficiency, and improves the qualification rate of workpieces. Here, it should be noted that the spraying station is a part of the spraying production line, and it can fix the workpiece to be sprayed.

[0039] Furthermore, the automatic spray gun spraying mechanism of the spraying production line further includes a controller 4 and a control panel 5. The control panel 5 is installed on the bottom wall of one end of the transverse movement assembly 2 away from the spray gun assembly 3. The controller 4 is located below the control panel 5 and is connected to one side wall of the lifting assembly 1. The controller 4 is electrically connected to the control panel 5 and is respectively electrically connected to the spray gun assembly 3, the lifting assembly 1 and the transverse movement assembly 2. By setting the control panel 5 and the controller 4, it can realize the unified management and control of the lifting assembly 1, the transverse movement assembly 2 and the spray gun assembly 3, realizing a high degree of automation of the spraying process, thereby enabling the operator to operate more intuitively, reducing the operation steps, reducing the risk of misoperation, improving work efficiency, and making the operation simpler.

[0040] Specifically, the controller 4 includes a fifth housing 41 and a PLC control assembly 42. The fifth housing 41 is connected to the side wall of the lifting assembly 1, and the PLC control assembly 42 and the first driving member 12 are both located in the fifth housing 41 and connected to the outer wall of the lifting assembly 1. The PLC control assembly 42 is electrically connected to the spray gun assembly 3, the lifting assembly 1, the traverse assembly 2 and the control panel 5, respectively, so that the movement of the lifting assembly 1, the traverse assembly 2 and the spray gun assembly 3 can be accurately controlled according to a preset program, which greatly improves the automation level and control accuracy of the spraying operation.

[0041] Furthermore, the lifting assembly 1 includes a first housing 11 , a first driving member 12 , a first threaded rod 13 , a first sliding block 14 and a lifting rod 15 .

The top of the lifting rod 15 passes through the top of the first shell 11 and is detachably connected to the lateral side wall of the transverse movement assembly 2. The bottom of the first threaded rod 13 is connected to the first drive member 12 through the first reducer 16, which can realize that the first slider 14 drives the lifting rod 15 to rise and fall slowly, avoiding the first slider 14 driving the lifting rod 15 to rise and fall too fast, resulting in the spray gun assembly 3 being unable to accurately reach the spraying position, and the torque output of the threaded transmission is increased by reducing the torque, ensuring the strong lifting and powerful lifting, while also protecting the drive member and avoiding overload damage. The bottom of the lifting rod 15 is inserted into the first slider 14 and is detachably connected to the first slider 14. The top of the first threaded rod 13 passes through the first slider 14 and the lifting rod 15 and is placed inside the lifting rod 15. The first slider 14 is threadedly matched with the first threaded rod 13, so that the first threaded rod 13 and the first slider 14 form a screw nut structure, so that the first slider 14 can drive the lifting rod 15 to lift vertically. By setting the first threaded rod 13 and the first slider 14, it is possible to enable the first driving member 12 to accurately control the rotation of the first threaded rod 13, so as to achieve the smooth and accurate up and down movement of the lifting rod 15, and it ensures the continuity and stability of the action during the lifting process, and can maintain a high degree of spraying accuracy even in continuous operation, avoiding uneven coating caused by equipment vibration.

It can limit the position of the first slider 14, and at the same time ensure that the first slider 14 rises or falls smoothly in a straight line during the lifting process, avoiding the problem of uneven spraying caused by skew or shaking, and significantly improving the accuracy and consistency of the spraying operation. Preferably, there are two guide rods 17 and guide blocks 18 respectively, and the vertical central axes of the two guide rods 17 and guide blocks 18 are parallel to each other and located in the same horizontal plane, which can make the movement of the first slider 14 on the first threaded rod 13 more stable.

A limiting groove 211 is provided on the side wall of the second housing 21 facing the lifting rod 15, and the second slider 23 is placed in the limiting groove 211, which can limit the transverse movement of the second housing 21 relative to the second slider 23, making the spray gun assembly 3 and the second housing 21 more stable and not prone to deviation during movement. The bottom of the second slider 23 is detachably connected to the top of the lifting rod 15. The second slider 23 is threadedly connected to the second threaded rod 22, and the driving part 24 is detachably installed on the top of the end of the second housing 21 away from the spray gun assembly 3.

Matching T-shaped grooves and T-shaped blocks are provided on the limit plate 26 and the limit block 25 so that the limit block 25 and the limit plate 26 are slidably connected relative to each other, thereby preventing the separation between the limit block 25 and the limit plate 26 and further enhancing the structural stability of the transverse movement assembly 2. Among them, one side of the limit plate 26 facing the limit block 25 is a T-shaped block or a T-shaped groove, and one side of the limit block 25 facing the limit plate 26 is a T-shaped groove and a T-shaped block that cooperate with the T-shaped block or the T-shaped groove.

Through the combined transmission method of the first fixed pulley 243, the second fixed pulley 244 and the transmission belt 245, the torque required for the second driving member 242 to directly drive the second threaded rod 22 is reduced, the energy consumption is lowered, and the smoothness of the system operation is improved.

[0047] Furthermore, the spray gun assembly 3 includes a fourth housing 31, a third driving member 32, two spray gun heads 33, and a second speed reducer 34. One side wall of the fourth housing 31 is detachably connected to one end of the third housing 241 away from the driving portion 24.

The two spray gun heads 33 are located on both sides of the fourth housing 31 and are arranged in parallel. The opposite side walls of the two spray gun heads 33 are connected to the second speed reducer 34 through a transmission shaft 341 passing through the outer wall of the fourth housing 31. The output end of the third driving member 32 is connected to the second speed reducer 34. By providing the second speed reducer 34, it can slow down the transmission speed of the transmission shaft 341, so that when the spray gun head 33 sprays on the surface of an irregular and complex workpiece, the spraying effect is more uniform and delicate, and the qualified rate of the workpiece is higher. The central axis of the transmission shaft 341 is perpendicular to the central axis of the second threaded rod 22. The third driving member 32 can drive the two transmission shafts 341 to rotate through the second speed reducer 34, so as to drive the two spray gun heads 33 to rotate circumferentially around the central axis of the transmission shaft 341 at the same time. By providing two spray gun heads 33 arranged in parallel and capable of synchronously rotating circumferentially, the coverage area of a single spraying is significantly expanded, the spraying blind area is reduced, the uniform distribution of the coating on the workpiece surface is ensured, and the spraying quality and efficiency are improved.

[0048] With the above structure, the working principle of an automatic spray gun spraying mechanism of a spraying production line according to this embodiment is as follows:

Then, touch the control panel 5 so that the control panel 5 transmits the electrical signals for driving the lifting assembly 1, the transverse movement assembly 2, and the spray gun assembly 3 to the PLC control assembly 42. Then, the PLC control assembly 42 transmits the electrical signals to the lifting assembly 1, the transverse movement assembly 2, and the spray gun assembly 3 respectively, so as to move the lifting assembly 1, the transverse movement assembly 2, and the spray gun assembly 3 respectively.

[0050] According to the position of the workpiece, the first driving member 12 is driven to drive the first threaded rod 13 to rotate, thereby driving the first slider 14 to rise vertically, so that the lifting rod 15 rises vertically, and then driving the transverse movement assembly 2 and the spray gun assembly 3 to rise vertically. When the lifting assembly 1 rises to the specified height, the driving of the first driving member 12 is stopped to fix the heights of the transverse movement assembly 2 and the spray gun assembly 3. Then, the second driving member 242 is driven to drive the first fixed pulley 243 to rotate, and then drive the second fixed pulley 244 to rotate through the transmission belt 245, so that the second threaded rod 22 rotates. Since the second slider 23 is fixed to the lifting rod 15, the second housing 21, the driving portion 24, and the spray gun assembly 3 move horizontally along the central axis of the second threaded rod 22 toward the workpiece. When the spray gun assembly 3 reaches the specified position as it moves with the transverse movement assembly 2, the driving of the second driving member 242 is stopped to keep the horizontal distance between the spray gun assembly 3 and the workpiece fixed. The spray gun head 33 is driven to start spraying the workpiece.

[0051] After a part of the surface of the workpiece is sprayed, the third driving member 32 is driven to drive the two transmission shafts 341 to rotate, and then drive the two spray gun heads 33 to rotate around the central axis of the transmission shafts 341, so as to spray the surfaces of other parts of the workpiece. During this period, if the positions of the lifting assembly 1 and the transverse movement assembly 2 do not meet the requirements, the contact control panel 5 is used to drive the lifting assembly 1 and the transverse movement assembly 2 to continue driving the spray gun assembly 3 to move, so as to spray all the surfaces of the workpiece.

[0052] After the spraying is completed, the sprayed workpiece is taken out for the next process, and then other unsprayed workpieces are continuously placed at the spraying station, and the above movements are continued to complete the spraying of the new workpiece, which will not be elaborated here.
