Description

Technical Field

[0001] The utility model relates to the technical field of curing devices, in particular to an adjustable UV baking device. Background Art

[0002] UV glue is also called photosensitive glue, ultraviolet light curing glue, and shadowless glue. It is a type of adhesive that must be cured by ultraviolet light. It can be used as an adhesive, and can also be used as a glue for paints, coatings, inks, etc. For some UV glues with higher viscosity and higher bonding strength, high-temperature baking is usually required to cure the glue to improve curing efficiency and bonding strength.

[0003] Common UV curing devices are mainly composed of ultraviolet light sources with heating functions. Due to the limitations of the materials themselves, such light sources are usually strip-shaped or point-shaped. For large-area curing, the use of point-shaped light sources requires the use of a large number of light spots, so strip-shaped light sources are usually used. Strip-shaped light sources can perform well for workpieces with glue in the entire area, but are slightly inappropriate for glue distributed in strips. This is mainly because when the direction of the glue is not parallel to the direction of the strip-shaped light source, the ultraviolet intensity and temperature of the glue in different parts of the glue will be slightly different, which will cause uneven and asynchronous curing of the glue. For some glues that will produce strong shrinkage after curing, it will also have a certain impact on the workpiece and affect the product quality. Therefore, a baking device that can adjust the angle of the lamp tube in real time according to the situation of the glue can be designed. Utility Model Content

[0006] Furthermore, the lamp tube includes a plurality of mutually parallel first lamp tubes and a plurality of mutually parallel second lamp tubes, and the first lamp tubes are perpendicular to the second lamp tubes.

[0007] Furthermore, the irradiation device also includes a slide groove arranged on the side of the turntable, and a plurality of L-shaped limit plates arranged on the inner top wall of the shell; the limit plate is slidably arranged in the slide groove at one end away from the shell.

[0008] Furthermore, the driving device includes a connecting rod connected to the turntable, a driving plate arranged above the shell, and a power assembly for driving the driving plate to rotate; the connecting rod passes through the shell and is connected to the driving plate.

[0026] Example

[0027] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 4 As shown, the adjustable UV baking device of this embodiment includes an operating table 11, a shell 12 covered on the operating table 11, and an irradiation device arranged at the upper end of the shell 12; the irradiation device includes a turntable 14 arranged on the inner wall of the shell 12, a plurality of lamp tubes arranged on the lower side of the turntable 14, and a driving device for driving the turntable 14 to rotate. Specifically, when in use, the workpiece to be baked is placed on the operating table 11, and is sent into the shell 12 for baking (a conveyor belt or the like can be set on the operating table 11 to automatically transport the workpiece). During the baking process, the lamp emits ultraviolet light, and the glue on the workpiece is cured by the ultraviolet light and the heat generated by the lamp. After curing, the shell 12 can be sent out. During the curing process, some workpiece surfaces are not completely coated with glue, but are coated with strips, and the distribution is not completely parallel. At this time, the turntable 14 can be driven to rotate by a driving device, and then the angle of the lamp can be adjusted so that the lamp is kept as parallel as possible to the glue coating position. In this way, the glue at the glue coating position can not only cure faster, but also cure more evenly. For some glues that will shrink to a certain extent during the curing process, the shrinkage process is also more uniform. Therefore, it can not only improve production efficiency, but also improve production quality to a certain extent.

[0028] The lamp tubes in this embodiment include a plurality of mutually parallel first lamp tubes 15 and a plurality of mutually parallel second lamp tubes 16, wherein the first lamp tubes 15 are perpendicular to the second lamp tubes 16. Specifically, since the turntable 14 is a circular structure, the number of lamp tubes can be increased by providing mutually perpendicular first lamp tubes 15 and second lamp tubes 16. In order to improve the curing efficiency, multiple irradiation devices can also be provided to improve the curing effect.

[0029] The irradiation device in this embodiment further includes a slide groove 17 provided on the side of the turntable 14, and a plurality of L-shaped limit plates 13 provided on the inner top wall of the housing 12; the limit plate 13 is slidably provided in the slide groove 17 at one end away from the housing 12. Specifically, the limit plate 13 can play a certain supporting role on the turntable 14, so that the turntable 14 can rotate more smoothly.

[0030] The driving device in this embodiment includes a connecting rod 18 connected to the turntable 14, a driving plate 19 arranged above the housing 12, and a power assembly for driving the driving plate 19 to rotate; the connecting rod 18 passes through the housing 12 and is connected to the driving plate 19. The power assembly includes a first hinged rod 110 connected to the upper side wall of the driving plate 19, an electric push rod 111 hinged to the first hinged rod 110, and a second hinged rod 112 arranged at an end of the electric push rod 111 away from the first hinged rod 110; the second hinged rod 112 is connected to the outer side wall of the housing 12. Specifically, the electric push rod 111 pushes the first hinged rod 110 to drive the driving plate 19 to rotate, and then drives the turntable 14 to rotate through the connecting rod 18. The electric push rod 111 is used because it has better accuracy, can stay at any angle, and only needs to control the turntable 14 to rotate back and forth within a range of 90 degrees. It can also use structures such as motors, gears or transmission belts, but its cost is relatively high.

[0031] When the electric push rod 111 in this embodiment is in the shortest retracted position, its axis does not intersect with the axis of the drive plate 19. Specifically, in this way, the electric push rod 111 can normally push the drive plate 19 to rotate.

[0032] The present embodiment also includes a ventilation device connected to the shell 12; the ventilation device includes an air outlet opened at one end of the shell 12, an exhaust hood 21 covered at the air outlet, a negative pressure pipe 22 connected to the exhaust hood 21, and a negative pressure machine connected to the negative pressure pipe 22. The ventilation device also includes an air inlet provided at the end of the shell 12 away from the air outlet, an air inlet hood 23 covered at the air inlet, and a fan 24 provided at the end of the air inlet hood 23 away from the air inlet, and a filter cotton is provided at the fan 24. An electric heating device is provided in the air inlet hood 23. Specifically, the lamp tube is a UV lamp tube, and the light it emits is mainly ultraviolet light, and ultraviolet light will inevitably produce a certain amount of ozone, and the ozone emitted will have a certain impact on the surrounding work, so by providing a ventilation device, the generated ozone can be discharged in a direction. The fan 24 on the air inlet hood 23 slowly draws in external air, heats it in the air inlet hood 23 through the electric heating device and then sends it into the shell 12. The negative pressure machine then draws the air in the shell 12 through the negative pressure pipe 22 and the exhaust hood 21, and the two form convection. The convection of gas is relatively slow, which is to prevent the normal temperature air from cooling the inside of the shell 12 and affecting the curing effect.

[0033] In summary, the adjustable UV baking device of this embodiment, when in use, places the workpiece to be baked on the operating table 11, and sends it into the shell 12 for baking. During the baking process, the lamp tube emits ultraviolet light, and the glue on the workpiece is cured by the ultraviolet light and the heat generated by the lamp tube. After curing, it can be sent out of the shell 12. During the curing process, some workpiece surfaces are not completely coated with glue, but are coated with strips, and the distribution is not completely parallel. At this time, the turntable 14 can be driven to rotate by the driving device, and then the angle of the lamp tube can be adjusted so that the lamp tube is kept as parallel as possible to the glue coating position. In this way, the glue at the glue coating position can not only cure faster, but also cure more evenly. For some glues that will shrink to a certain extent during the curing process, the shrinkage process is also more uniform. Therefore, it can not only improve production efficiency, but also improve production quality to a certain extent.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
