[0024] Combination Figure 3 and Figure 4 As shown, the anti-collision assembly 7 includes an upper connecting block 16, an anti-collision sensor 17, a sensor instrument, and a lower connecting block 18. The upper connecting block 16 is connected to the output end of the lifting cylinder 14, and the lower connecting block 18 is connected to the spray valve 15. Both the upper connecting block 16 and the lower connecting block 18 are L-shaped plate structures. The anti-collision sensor 17 is connected between the upper connecting block 16 and the lower connecting block 18. The top of the anti-collision sensor 17 is fixedly connected to the upper connecting block 16 with screws, and the bottom of the anti-collision sensor 17 is fixedly connected to the lower connecting block 18 with screws.

[0025] Combination Figure 4As shown, the anti-collision sensor 17 is connected to the upper connecting block 16 via a positioning structure 19. The positioning structure 19 is fixedly installed at the bottom of the upper connecting block 16. One side of the positioning structure 19 is provided with a sensor positioning groove 34 for positioning and engaging with the anti-collision sensor 17, and a lower connecting block positioning groove 35 for positioning and engaging with the lower connecting block 18. To install the anti-collision sensor 17, the side of the anti-collision sensor 17 is first positioned and engaged with the sensor positioning groove 34, and then the upper connecting block 16 and the anti-collision sensor 17 are connected using screws.

[0026] When the anti-collision sensor 17 is not installed, the upper connecting block 16 and the lower connecting block 18 are stacked. One corner of the lower connecting block 18 is positioned and engaged with the lower connecting block positioning groove 35. After the positioning and engagement, the upper connecting block 16 and the lower connecting block 18 are then connected by screws.

[0027] The anti-collision sensor 17 is cylindrical, the sensor positioning groove 34 is an arc-shaped groove that adapts to the side of the anti-collision sensor 17, and a protrusion is provided at one end of the positioning structure 19 to form a lower connecting block positioning groove 35.

It allows for easy positioning and fixed connection of the upper connecting block 16 and the lower connecting block 18, preventing displacement or loosening.

[0030] The overall design of the positioning structure 19 not only improves the ease of installation, making it suitable for both installations with and without the anti-collision sensor 17, but also offers high installation compatibility and flexibility. Simultaneously, it effectively enhances the stability and reliability of the anti-collision component 7, making the entire spraying equipment safer and more efficient during operation.

[0031] The sensor instrument is electrically connected to the anti-collision sensor 17. When the equipment is running, the impact force threshold of the sensor instrument is set to an appropriate value.

[0033] In this embodiment, the Z-axis servo motor 25 drives the Z-axis mounting plate 24 to move precisely in the vertical direction, thereby adjusting the height of the lifting cylinder 14 and the spraying valve 15. The coordinated operation of the X-axis module 8, Y-axis module 9, and Z-axis module 10 enables the spraying valve 15 to be flexibly positioned in three-dimensional space, greatly improving the accuracy and efficiency of spraying. Simultaneously, the use of the servo motor ensures the smoothness and accuracy of the movement, further enhancing the overall performance of the equipment.

[0034] Combination Figure 3 As shown, the Z-axis mounting plate 24 is provided with mounting holes for mounting the dual-valve adjustable spacing mounting plate 11. The dual-valve adjustable spacing mounting plate 11 is connected to the Z-axis servo motor 25. The dual-valve adjustable spacing mounting plate 11 allows the spacing between the two spray valves 15 to be adjusted according to actual needs to accommodate objects of different sizes or shapes to be sprayed.

[0035] Furthermore, the track transmission mechanism 5 includes a fixed rail 26 and a moving rail 27. A fixed column 28 is fixedly installed at the bottom of the fixed rail 26 and is fixedly installed on the top of the upper frame 2. A slide rod 29 is fixedly installed on one side of the fixed column 28, and a moving column 30 is movably installed on the slide rod 29. The moving rail 27 is fixedly installed on the moving column 30, so that the distance between the fixed rail 26 and the moving rail 27 can be adjusted as needed.

[0036] In this embodiment, the chain motor 31 drives the fixed rail 26 and the moving rail 27 to move smoothly along the slide bar 29, thereby driving the object to be sprayed to make precise displacement in the horizontal direction.

[0037] Combination Figure 2As shown, the upper frame 2 is equipped with a display 39 and operation buttons 40. A tri-color light 41 is installed on the top of the upper frame 2. The lower frame 3 is equipped with a frame door panel 36. Casters 37 and leveling feet 38 are fixedly installed at the bottom of the lower frame 3. The display 39 is used to display the operating status and parameter information of the spraying equipment, facilitating real-time monitoring and adjustment by the operator. The operation buttons 40 provide a series of functions, such as starting, stopping, and adjusting the spraying speed, enabling the operator to easily control the operation of the spraying equipment. The tri-color light 41 indicates different states of the spraying equipment through different colored lights.

[0038] The control system in this embodiment includes components such as a controller, a display 39, operation buttons 40, and a tri-color light 41. The controller can be a high-performance industrial computer + motion controller, a high-performance industrial computer + programmable controller, or a microcontroller, etc.

[0039] Working Principle: Before operation, the impact force threshold of the sensor instruments must be set to an appropriate value. After editing the spraying trajectory path, click the equipment's overall reset button and then start automatic operation. If the operator accidentally places the product upside down into the spraying path, it will inevitably collide with capacitors, resistors, heat sinks, etc. on the PCB circuit board during the spraying of the conformal coating. When the spraying valve hits these components, the impact force generated reaches the previously set force. For example, if the spraying valve 15 hits the heat sink on the PCB board, the anti-collision sensor 17 will output an IO signal to the equipment controller. The controller will immediately alarm and stop the machine to protect the circuit board and the spraying valve from damage. Since a certain force will also be generated during normal operation or acceleration and deceleration, the impact force threshold must be set appropriately. If the setting is too small, an alarm will be triggered even without impact during normal operation; if the setting is too large, there will be no alarm or shutdown when impacting components.
