Description

Technical Field

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

[0002] A UV-LED curing machine is a light source device that emits ultraviolet light to cure UV adhesives. It uses electromagnetic radiation to irradiate the coating, producing reactions such as radiation polymerization, radiation crosslinking, and radiation bonding. It is generally suitable for large-area bonding, fixing, and assembly in industries such as crystal imaging, glass crafts, glass furniture, and film publishing, and is an indispensable fast curing light source.

[0003] However, existing UV-LED curing machines have the following problems:

[0004] During the photocuring process, operators are required to feed the material, and after photocuring is completed, operators are required to unload the material. The entire process requires a high degree of operator involvement, is labor-intensive, has a low degree of automation, and is inefficient, which cannot meet production needs. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a UV-LED curing machine with automatic feeding and unloading, simple structure, high stability and conveying function.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A UV-LED curing machine with conveying function includes a base, on which a base plate is fixedly installed by support legs. Conveying brackets are fixedly installed on both sides of the base plate, with a gap between the two conveying brackets. A conveyor belt is installed on the conveying bracket, with the upper end of the conveyor belt located above the conveying bracket. A UV curing component is installed between the two conveying brackets.

[0008] The base has a feeding structure and a discharging structure installed at its two ends, and the feeding structure and the discharging structure have the same structure. Both the feeding structure and the discharging structure include a material moving component and a material supporting component. The material moving component is used to drive the material box on the material supporting component to move.

[0009] In this system, the material box contains the items to be photocured. The material box is stacked vertically on a material support assembly, which moves the material box vertically. The loading structure's material moving assembly moves the material box onto two conveyor belts, while the unloading structure's material moving assembly moves the material box from the two conveyor belts onto the material support assembly. This automates loading and unloading, improving efficiency and reducing operator workload. The conveyor belts then move the material box to the photocuring assembly, which irradiates the items within the material box to achieve the photocuring effect.

[0010] The material moving assembly includes a horizontal screw, and two supports are fixedly installed on the base. The horizontal screw is connected to the supports via bearings. A horizontal moving motor is fixedly installed on one of the supports. The output shaft of the horizontal moving motor is fixedly connected to one end of the horizontal screw. A nut is threaded onto the horizontal screw, and the nut is fixedly installed on a column. The lower end of the column is slidably fitted with the base. A hydraulic cylinder is fixedly installed on the column. A cross arm is fixed to the cylinder rod of the hydraulic cylinder. A connecting seat is fixedly installed on the cross arm, and the connecting seat is equipped with an opposing clamping structure.

[0011] The opposing clamping structure includes two bidirectional screws with opposite threads at both ends. The bidirectional screws are connected to a connecting seat via bearings. Both ends of the bidirectional screws are threadedly connected to threaded blocks, and clamping plates are fixedly mounted on the threaded blocks. One end of the bidirectional screw passes through the connecting seat and is fixedly connected to the output shaft of the clamping motor. The clamping motor is fixedly mounted on the connecting seat. The two clamping plates located at the same end are fixedly connected by a connecting plate.

[0012] The clamp is fixedly fitted with a rubber pad.

[0013] The connecting plate is fixedly mounted with a lifting motor. The output shaft of the lifting motor is fixed with a pin. The end of the pin away from the lifting motor is connected to the connecting plate through a bearing seat. A support plate is fixedly mounted on the pin. The size of the support plate is smaller than the interval between the two conveying brackets. The support plate is located between the two clamping plates.

[0014] The material support assembly includes two frames. A support rod is fixed between the lower end of the frame and the base. A lifting screw is installed inside the frame via a bearing. The lower end of the lifting screw passes through the frame and is fixedly connected to the output shaft of the lifting motor. The lifting motor is fixedly installed at the lower end of the frame. A connecting block is threaded onto the lifting screw. A tray is fixed between the two connecting blocks, and the material box is stacked on the tray.

[0015] The base is fixed upward with six positioning rods, which are divided into three groups and set at three positions on the support plate.

[0016] In summary, this UV-LED curing machine with conveying function has the advantages of automatic feeding and unloading, simple structure, and high stability. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0024] like Figure 1-6 As shown, a UV-LED curing machine with a conveying function includes a base 1, on which a base plate is fixedly installed by support legs. Conveying brackets 2 are fixedly installed on both sides of the base plate, with a gap between the two conveying brackets. A conveyor belt 3 is installed on the conveying bracket, with the upper end of the conveyor belt located above the conveying bracket. The conveyor belt drives the material box to move, avoiding contact between the material box and the conveying bracket. A UV curing component 4 is installed between the two conveying brackets.

[0025] The base is equipped with a feeding structure and a discharging structure at its two ends, and the feeding structure and the discharging structure are identical in structure. Both the feeding structure and the discharging structure include a material moving component and a material supporting component. The material moving component is used to move the material box 5 on the material supporting component.

[0026] In this system, the material box contains the items to be photocured. The material box is stacked vertically on a material support assembly, which moves the material box vertically. The loading structure's material moving assembly moves the material box onto two conveyor belts, while the unloading structure's material moving assembly moves the material box from the two conveyor belts onto the material support assembly. This automates loading and unloading, improving efficiency and reducing operator workload. The conveyor belts then move the material box to the photocuring assembly, which irradiates the items within the material box to achieve the photocuring effect.

[0027] Specifically, the photocuring assembly includes a housing and a curing lamp installed inside the housing. The housing is fixedly connected to the conveyor support via a housing frame, which is an existing structure.

[0028] In implementation, the material moving assembly includes a horizontal screw 6. Two supports are fixedly installed on the base. The horizontal screw is connected to the supports via bearings. A horizontal moving motor 7 is fixedly installed on one of the supports. The output shaft of the horizontal moving motor is fixedly connected to one end of the horizontal screw. A nut is threaded onto the horizontal screw. The nut is fixedly installed on a column 8. The lower end of the column slides against the base. A hydraulic cylinder 9 is fixedly installed on the column. A cross arm 10 is fixedly attached to the cylinder rod of the hydraulic cylinder. A connecting seat 11 is fixedly installed on the cross arm. The connecting seat is equipped with an opposing clamping structure. During horizontal movement, the horizontal moving motor drives the horizontal screw to rotate, which in turn drives the column to move via the nut. The hydraulic cylinder drives the cross arm to move up or down. The opposing clamping structure can clamp the material box, thus enabling loading or unloading through the material moving assembly.

[0029] In implementation, the opposing clamping structure includes two bidirectional screws 12 with opposite thread directions at both ends. The bidirectional screws are connected to a connecting seat via bearings, and threaded blocks are threaded to both ends of each screw. Clamping plates 13 are fixedly mounted on the threaded blocks. One end of each bidirectional screw passes through the connecting seat and is fixedly connected to the output shaft of a clamping motor 14, which is fixedly mounted on the connecting seat. The two clamping plates at the same end are fixedly connected by a connecting plate 15. Thus, the clamping motor drives the bidirectional screws to rotate, which in turn moves the clamping plates via the threaded blocks. The connecting plate prevents the clamping plates from rotating, thereby achieving clamping of the material box.

[0030] During implementation, the clamping plate is fixedly equipped with a rubber pad. This increases the friction between the clamping plate and the material box, thus better clamping the material box.

[0031] In practice, a lifting motor 16 is fixedly mounted on the connecting plate. A pin is fixed to the output shaft of the lifting motor. The end of the pin away from the lifting motor is connected to the connecting plate via a bearing seat. A support plate 17 is fixedly mounted on the pin. The size of the support plate is smaller than the gap between the two conveying supports, and the support plate is located between the two clamping plates. The lifting motor drives the connecting plate to rotate, causing the connecting plate to rotate below the material box, providing an auxiliary effect and preventing the material box from falling off the clamping plates.

[0032] In implementation, the material support assembly includes two frames 18. A support rod is fixed between the lower end of each frame and the base. A lifting screw 19 is installed within each frame via bearings. The lower end of the lifting screw passes through the frame and is fixedly connected to the output shaft of a lifting motor. The lifting motor is fixedly installed at the lower end of the frame. A connecting block 20 is threaded onto the lifting screw. A support plate 21 is fixed between the two connecting blocks, and the material box is stacked on the support plate. Thus, the lifting motor drives the lifting screw to rotate, which in turn moves the support plate vertically via the connecting blocks, thereby moving the material box.

[0033] In implementation, the base is fixed upwards with six positioning rods 22, which are divided into three groups and set at three positions on the tray. The three positions are rear, left, and right, which limit the three positions of the material box and improve the accuracy of loading and unloading. There are no positioning rods at the front to facilitate the loading and unloading of the material box from the tray.

[0034] Specifically, a drive shaft and a driven shaft are rotatably mounted on the conveyor support. The conveyor belt is sleeved on the outside of the drive shaft and the driven shaft. A drive motor is fixedly mounted on the conveyor support. One end of the drive shaft is fixedly connected to the output shaft of the drive motor. This is an existing structure that can be directly installed.

[0035] Feeding process:

[0036] 1. Place the items to be light-cured in the material box. The material boxes are stacked vertically on the pallet of the feeding structure. The positioning rod is used to position the material boxes. The lifting motor drives the lifting screw to rotate, which in turn moves the pallet so that the material box at the top is at the standard height.

[0037] 2. The horizontal moving motor rotates through the horizontal screw, which in turn drives the column to move to one side of the material box. The hydraulic cylinder retracts and drives the opposing clamping component to clamp the material box located at the top. Then the hydraulic cylinder extends and resets, and the lifting motor drives the pallet to rotate to the bottom of the material box to prevent the material box from falling.

[0038] 3. The horizontal moving motor rotates in the opposite direction through the horizontal screw, driving the column to move to one side of the conveyor support. The hydraulic cylinder retracts, driving the material box to descend. The bidirectional clamping assembly resets, releasing the clamp. The lifting motor drives the pallet to reset, and the material box is placed on the conveyor belt.

[0039] 4. After the bidirectional clamping component has finished clamping a material box, the lifting component will lift the material box up by the height of one material box to facilitate the next loading.

[0040] The unloading process is the reverse of the loading process.

[0041] Specifically, this application also includes a PLC controller for controlling the operation of the electrical components therein.

[0042] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
