Description

Technical Field

[0001] This utility model relates to the field of UV curing technology, and in particular to a UV curing machine with double-sided curing function. Background Technology

[0002] UV curing technology is a highly efficient and environmentally friendly material surface treatment technology that is widely used in many fields such as printing, coating, electronics, optics, medical, and packaging. Its principle is to use ultraviolet light of a specific wavelength to irradiate liquid materials containing photoinitiators, so that the materials undergo photochemical reactions in a very short time, realizing the transformation from liquid to solid state.

[0003] Existing UV curing equipment typically places the UV light source above the workpiece to be cured. When processing double-sided curing parts, the first side needs to be cured first, the workpiece is removed from the equipment and flipped over before being sent back into the curing equipment for the second side curing. This flipping operation greatly reduces production efficiency, and manual flipping increases labor costs. Moreover, in high-temperature or specific production environments, the labor intensity of workers is high, and there are safety hazards.

[0004] Therefore, it is necessary to design a UV curing machine with double-sided curing function. Utility Model Content

[0005] In order to overcome the disadvantages of manually flipping the cured parts, which not only reduces production efficiency but also poses safety hazards, this utility model provides a UV curing machine with double-sided curing function.

[0006] The technical solution of this utility model is as follows: a UV curing machine with double-sided curing function, comprising a mounting frame, a conveyor belt assembly, a curing mechanism, a first baffle, a second baffle, an electric push rod, a rack, a gear, a mounting plate, a support block, a T-shaped clamp, an infrared sensor, a guide rod, a motor, a bidirectional lead screw, and a control cabinet. Mounting frames are provided on the front and rear sides of the device. Two conveyor belt assemblies are wound around the middle of the two mounting frames, with the two conveyor belt assemblies located on the left and right sides of the mounting frames respectively. Curing mechanisms are fixedly installed on both the left and right sides of the mounting frames, with each curing mechanism located above its corresponding conveyor belt assembly. A first baffle is symmetrically installed on the upper left side of the two mounting frames, and a second baffle is symmetrically installed on the upper right side of the two mounting frames. The left sides of the two second baffles are hinged together by a pivot. The mounting plate is located between two conveyor belt groups. An electric push rod is fixedly installed on the middle right side of the front baffle. A rack is fixedly connected to the telescopic rod of the electric push rod. A gear is fixedly connected to the left rotating shaft of the second baffle on the front mounting frame. The gear meshes with the rack. A notch is opened in the middle of the mounting plate. Support blocks are fixedly connected to both the front and rear sides of the notch on the lower end face of the mounting plate. A guide rod is fixedly installed in the middle between the two support blocks. A two-way screw is rotatably installed at the lower part between the two support blocks. A motor is fixedly installed on the front support block. The output shaft of the motor is fixedly connected to the two-way screw. T-shaped clamps are symmetrically slidably installed on the notch of the mounting plate. The lower middle part of the T-shaped clamp is slidably connected to the guide rod. The lower part of the T-shaped clamp is threaded to the two-way screw. Infrared sensors are fixedly connected to the upper part of both T-shaped clamps.

[0007] As a further preferred option, it also includes a control cabinet, which is fixedly installed in the middle of the front mounting bracket. The control cabinet is electrically connected to the infrared sensor and the motor.

[0008] As a further preferred option, it also includes rubber pads, with rubber pads fixed to the ends of the T-shaped clamps that are close to each other.

[0009] As a further preferred embodiment, the curing mechanism includes a gantry frame, guide rods, screws, mounting frames, and UV lamps. Two gantry frames are fixedly connected between the upper parts of the two mounting frames. Both gantry frames are located above the corresponding conveyor belt groups. Screws are threadedly connected to the middle of the upper end face of each of the two gantry frames. Two guide rods are slidably inserted through the upper end face of each of the two gantry frames. Each pair of guide rods is located on the front and rear sides of the corresponding screw. A mounting frame is fixedly connected between the lower end of each screw and the corresponding two guide rods. UV lamps are fixedly installed between the front and rear side walls of the two mounting frames. Both UV lamps are electrically connected to the control cabinet.

[0010] As a further preferred option, it also includes a dust hood, a fan, and a dust collection box. Dust hoods are fixedly installed on the left side of both mounting frames, and dust collection boxes are fixedly installed in the middle of the front side of both gantry frames. The two dust collection boxes are connected to the corresponding dust hoods through dust suction pipes. Fans are fixedly installed on the dust suction pipes at the top of the two dust collection boxes, and both fans are electrically connected to the control cabinet.

[0011] As a further preferred option, the mounting plate is positioned above the two conveyor belt sets, with a sufficient gap between it and the right conveyor belt set to allow the mounting plate to rotate.

[0012] The beneficial effects are as follows: After the workpiece is transported to the mounting plate by the conveyor belt assembly, the workpiece is clamped by two T-shaped clamping blocks driven by the motor, and the mounting plate and workpiece are automatically flipped by the electric push rod and gear, thus achieving the effect of automatically flipping the cured part.

Detailed Implementation

[0019] Example: A UV curing machine with double-sided curing function, such as Figures 1-5As shown, the device includes a mounting frame 1, a conveyor belt assembly 2, a curing mechanism 3, a first baffle 8, a second baffle 81, an electric push rod 9, a rack 10, a gear 11, a mounting plate 12, a support block 121, a T-shaped clamp 13, an infrared sensor 15, a guide rod 16, a motor 17, a bidirectional lead screw 18, and a control cabinet 22. Mounting frames 1 are located on both the front and rear sides of the device. Two conveyor belt assemblies 2 are wound around the middle of the two mounting frames 1, with the two conveyor belt assemblies 2 located on the left and right sides of the mounting frames 1, respectively.

A first baffle 8 is symmetrically installed on the upper left side of the two mounting frames 1, and a second baffle 81 is symmetrically installed on the upper right side of the two mounting frames 1. A mounting plate 12 is hinged between the left sides of the two second baffles 81 via a pivot shaft, and the mounting plate 12 is located between the two conveyor belt assemblies 2. An electric push rod 9 is screwed onto the middle right side of the first baffle 8 on the front side. A rack 10 is fixedly connected to the telescopic rod of the electric push rod 9. A gear 11 is fixedly connected to the left rotating shaft of the baffle 81 on the front mounting bracket 1. The gear 11 meshes with the rack 10. A notch is opened in the middle of the mounting plate 12. Support blocks 121 are fixedly connected to both the front and rear sides of the notch on the lower end face of the mounting plate 12. A guide rod 16 is fixedly installed in the middle between the two support blocks 121. A two-way lead screw 18 is rotatably installed at the lower part between the two support blocks 121. A motor is installed on the front support block 121 by screws. 17. The output shaft of motor 17 is fixedly connected to the bidirectional lead screw 18. T-shaped clamps 13 are symmetrically slidably provided on the notch of mounting plate 12. The lower middle part of the T-shaped clamp 13 is slidably connected to the guide rod 16. The lower part of the T-shaped clamp 13 is threadedly connected to the bidirectional lead screw 18. Infrared sensors 15 are fixedly connected to the upper part of both T-shaped clamps 13. Mounting plate 12 is located above the two conveyor belt groups 2, and there is a certain gap between it and the right conveyor belt group 2, which is sufficient to allow mounting plate 12 to rotate.

[0020] like Figure 1 As shown, it also includes a control cabinet 22. The control cabinet 22 is installed in the middle of the front mounting bracket 1 by screws. The control cabinet 22 is electrically connected to the infrared sensor 15 and the motor 17.

[0021] like Figure 4 As shown, it also includes a rubber pad 14, and the rubber pad 14 is fixed to one end of each of the two T-shaped clamps 13 that are close to each other.

[0022] like Figure 1 and Figure 2As shown, the curing mechanism 3 includes a gantry frame 31, guide rods 4, screws 5, mounting frames 6, and UV lamps 7. Two gantry frames 31 are fixedly connected between the upper parts of the two mounting frames 1. Both gantry frames 31 are located above the corresponding conveyor belt group 2. Screws 5 are threadedly connected to the middle of the upper end face of both gantry frames 31. Two guide rods 4 are slidably inserted through the upper end face of both gantry frames 31. Each pair of guide rods 4 is located on the front and rear sides of the corresponding screw 5. A mounting frame 6 is fixedly connected between the lower end of each screw 5 and the corresponding two guide rods 4. UV lamps 7 are fixedly installed between the front and rear side walls of the two mounting frames 6. Both UV lamps 7 are electrically connected to the control cabinet 22.

[0023] like Figure 1 As shown, it also includes a dust collection hood 19, a fan 20, and a dust collection box 21. The dust collection hood 19 is installed on the left side of both mounting frames 6 by screws. The dust collection box 21 is installed on the front middle of both gantry frames 31 by screws. The two dust collection boxes 21 are connected to the corresponding dust collection hood 19 by a dust collection pipe. The fan 20 is fixedly installed on the dust collection pipe at the top of the two dust collection boxes 21. The two fans 20 are electrically connected to the control cabinet 22.

[0024] This equipment is used when workpieces need to be cured. First, the mounting frame 6 can be moved up and down by rotating the screw 5, and the guide rod 4 can be used for guiding and limiting, thereby adjusting the curing range. After adjusting the height of the UV lamp 7, the workpiece is placed on the left conveyor belt group 2. The left conveyor belt group 2 transports the workpiece directly under the UV lamp 7 for UV curing. After one side of the workpiece is cured, the workpiece is transported to the mounting plate 12 by the left conveyor belt group 2. Then, the left conveyor belt group 2 is turned off, and the infrared sensor 15 on the T-shaped clamp 13 is turned off. After detecting the workpiece, a signal is transmitted to the control cabinet 22, which starts the motor 17. The output shaft of the motor 17 drives the bidirectional lead screw 18 to rotate. Under the drive of the bidirectional lead screw 18, the two T-shaped clamps 13 move synchronously inward along the guide rod 16 until the rubber pads 14 on the T-shaped clamps 13 contact the workpiece and complete the clamping. Then, the control cabinet 22 starts the electric push rod 9. The telescopic rod of the electric push rod 9 drives the rack 10 to extend horizontally and drives the gear 11 and its shaft to rotate, thereby causing the mounting plate 12 and the workpiece to rotate synchronously. When the workpiece rotates... After the rotation is completed, the motor 17 is started via the control cabinet 22. The output shaft of the motor 17 drives the bidirectional lead screw 18 to rotate in the opposite direction, causing the T-shaped clamp 13 to loosen. After the workpiece falls onto the right conveyor belt group 2, the electric push rod 9 is started via the control cabinet 22. The telescopic rod of the electric push rod 9 drives the rack 10 to return to horizontal reset and drives the gear 11 and its shaft to rotate, thereby driving the mounting plate 12 to rotate and reset. Then, the right conveyor belt group 2 is started, and the workpiece is transported to the area directly below the UV lamp 7 for reverse curing. When the reverse side of the workpiece is cured... After completion, the workpiece can be transported to the next process via the right conveyor belt group 2. After the curing machine finishes working, turn off the two conveyor belt groups 2 and the UV lamp 7. Drive the mounting plate 12 to reset between the two conveyor belt groups 2 via the control cabinet 22. When the workpiece is placed on the left conveyor belt group 2, the fan 20 can be started at the same time via the control cabinet 22. The dust and impurities on one side of the workpiece are sucked into the dust collection box 21 through the dust suction hood 19. The same process is repeated after the workpiece is flipped over. When the dust collection box 21 is full of dust and impurities, open the box door to clean the inside.
