[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0020] like Figure 1 As shown, an embodiment of this application discloses a negative pressure anti-splatter printing and coating machine, including a frame 1. A three-dimensional driving module 2 and a transmission module 3 located at the lower end of the three-dimensional driving module 2 are arranged inside the frame 1. A mounting frame 4 is provided at the driving end of the three-dimensional driving module 2. The mounting frame 4 includes a base plate 41. A nozzle 5 is arranged on the base plate 41. The base plate 41 has a hollow structure in the middle, so that the spraying part of the nozzle 5 can pass through the hollow part to spray the product. The nozzle 5 is provided with exhaust components 6 on both sides, which are used to extract the splashes during spraying.
[0021] It should be explained that the three-dimensional drive module 2 mentioned above can be a servo drive module or a lead screw mechanism.
[0022] During operation, the PCB board moves to the area below the nozzle 5 via the transmission module 3. The three-dimensional drive module 2 drives the mounting bracket 4 and the nozzle 5 to move in three-dimensional space, precisely spraying the PCB board. The conformal adhesive sprayed from the nozzle 5 directly applies to the PCB board through the cutouts in the base plate 41, effectively reducing adhesive waste. Simultaneously, the exhaust assembly 6 is activated, with the first exhaust port 61 and the second exhaust port 62 working together to quickly remove splatter generated during spraying through the exhaust channel, preventing contamination of the surrounding environment and equipment by the splatter and ensuring stable spraying quality.
[0023] In this embodiment, the exhaust assembly 6 includes an exhaust component, with a first exhaust port 61 at the upper end and a second exhaust port 62 at the lower end. An exhaust channel for connecting the first exhaust port 61 and the second exhaust port 62 is provided in the middle of the exhaust component. The first exhaust port 61 is connected to an external exhaust device through an exhaust pipe.
[0024] Specifically, the first exhaust port 61 can be a barrel-shaped structure, and the second exhaust port 62 can be a long strip-shaped structure, the length of which can be greater than or equal to the width of the nozzle 5.
[0025] The design of the aforementioned exhaust components allows the exhaust assembly 6 to more comprehensively cover the area sprayed by the nozzle 5, effectively removing splatter. Furthermore, the exhaust channel design ensures that splatter is quickly and smoothly removed, avoiding problems of clogging and accumulation.
[0026] In this embodiment, the mounting bracket 4 is provided with a first adjustment mechanism 7 for adjusting the position and angle of the exhaust assembly 6.
[0027] In this structure, the height and angle of the exhaust assembly 6 can be adjusted by the first adjustment mechanism 7, so that the exhaust assembly 6 can absorb splashes.
[0028] In this embodiment, the first adjustment mechanism 7 includes an L-shaped mounting block, which includes a first adjustment block 71 and a second adjustment block 72 connected to each other. The first adjustment block 71 is vertically provided with a first vertical groove, and the second adjustment block 72 is vertically provided with a second vertical groove. A third adjustment block 63 is provided on the side end of the exhaust component. The third adjustment block 63 is provided with a plurality of first adjustment holes. The system also includes a fourth adjustment block 73, which is provided with a plurality of second adjustment holes that cooperate with the second vertical groove and a third waist-shaped groove that cooperates with the plurality of first adjustment holes. The mounting bracket 4 is provided with a plurality of third adjustment holes that cooperate with the first vertical groove.
[0029] Specifically, by cooperating the first vertical groove and the third adjustment hole, the second vertical groove and the second adjustment hole, and the first adjustment hole and the third waist-shaped groove, the position and angle of the exhaust component 6 can be adjusted in three-dimensional space, increasing the flexibility and precision of the adjustment. In addition, the design of the L-shaped mounting block allows the exhaust component 6 to be stably installed on the mounting bracket 4, avoiding displacement or damage caused by vibration or impact.
[0030] In this embodiment, the mounting bracket 4 is provided with a curing component 8 and a second adjustment mechanism 9 for adjusting the curing component 8 on both outer sides.
[0031] The curing component 8 is used to cure the sprayed product, improving its quality and performance. The position and angle of the curing component 8 can be adjusted via the second adjustment mechanism 9 to accommodate products of different sizes and shapes.
[0032] In this embodiment, the second adjustment mechanism 9 includes a bending block, which includes a seventh adjustment block 91 and a fifth adjustment block 92 located on both sides of the seventh adjustment block 91. The seventh adjustment block 91 is vertically provided with a fourth vertical groove, and the mounting bracket 4 is provided with a fourth adjustment hole that cooperates with the fourth vertical groove. The fifth adjustment block 92 is provided with a fifth waist-shaped groove. The curing component 8 is provided with a sixth adjustment block 81 on both sides, and the sixth adjustment block 81 is provided with a fifth adjustment hole that cooperates with the fifth waist-shaped groove.
[0033] Specifically, by combining the fourth vertical groove and the fourth adjustment hole, and by combining the fifth waist-shaped groove and the fifth adjustment hole, the position and angle of the curing component 8 in three-dimensional space can be adjusted, further increasing the flexibility and adaptability of the adjustment, so that the curing component 8 can play a role in maximizing the curing effect on the product.
[0034] In this embodiment, a bent anti-collision bar is provided on the outer end of the curing component 8. A collision detection sensor 10 is provided on the adjacent side end of the curing component 8 where the bent anti-collision bar is installed. The bent anti-collision bar includes a first anti-collision bar 11 and a second anti-collision bar 12 connected to both ends of the first anti-collision bar 11. A spring assembly 13 is provided between the first anti-collision bar 11 and the curing component 8. When the first anti-collision bar 11 moves toward the curing component 8 under the action of an external force, the collision detection sensor 10 receives a collision signal from the second anti-collision bar 12.
[0035] Specifically, the collision detection sensor 10 mentioned above can be a micro switch, a laser sensor, etc.
[0036] Specifically, when the first anti-collision bar 11 collides with an obstacle during the spraying process, the spring assembly 13 is compressed, and the first anti-collision bar 11 moves towards the curing assembly 8, simultaneously moving the second anti-collision bar 12. At this time, the collision detection sensor 10 receives the collision signal from the second anti-collision bar 12 and immediately transmits the signal to the control system. After receiving the signal, the control system can react quickly, such as pausing the spraying operation or adjusting the spraying path, to avoid damaging the obstacle or affecting the spraying quality.
[0037] The design of this anti-collision mechanism not only improves the safety and stability of the negative pressure anti-splash printing and coating machine, but also effectively protects the surrounding environment and equipment, ensuring the smooth progress of the spraying operation.
[0038] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
