Description

Technical Field

[0001] This utility model relates to the field of curing technology, and in particular to a photocuring device. Background Technology

[0002] Medical polymer coatings are a key technology in modern medical devices, imparting functional properties such as lubrication, antibacterial properties, and anti-caking properties to the surface of medical devices. For medical safety, the coating needs to adhere firmly to the device surface, often requiring photocuring technology. This involves irradiating the coating solution onto the surface of the product with UV light, causing the coating to bond to the product. Consequently, coating equipment has become widely used by medical device manufacturers. This equipment typically includes a product suspension module, a coating module for applying the coating solution, and a photocuring module. The coated product is then transported to the photocuring module for curing. The photocuring module generally includes a curing chamber, which provides curing space for the product. A common method is to move the product from the coating chamber into the curing space using a moving mechanism. The curing chamber also contains a curing lamp for curing the product, which requires maintenance or replacement after a period of use. However, due to limited installation space, replacement is difficult. Furthermore, because a transparent insulating component, such as glass, is installed between the curing lamp and the product to be cured to prevent moisture or impurities, conventional replacement methods require disassembling this insulating component before the curing lamp can be repaired or replaced, thus posing a risk of damage to the glass or the curing lamp. Moreover, since the curing chamber is installed inside the coating equipment, replacing the curing lamp or the insulating component, or cleaning the inside of the curing chamber, requires disassembling the entire coating equipment, causing significant inconvenience.

[0025] Figure 1This is a schematic structural diagram of a photocuring apparatus 100 according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic top view of the lightbox assembly 20 of the light curing device 100 shown. Figure 3 yes Figure 1 A schematic rear view of the lightbox assembly 20 of the light curing apparatus 100 shown. Figure 4 yes Figure 1 A schematic perspective view of the lightbox assembly 20 of the light curing device 100 shown. Figures 1 to 4 As shown, in one specific embodiment, the photocuring apparatus 100 includes a curing chamber 10 and a light box assembly 20. The curing chamber 10 has a curing space for accommodating the product to be cured and multiple sides surrounding the curing space, wherein at least one side is a light source side. The light box assembly 20 is located on the light source side and includes one, two, or more light boxes 21. Each light box 21 is connected to a rotating member 22, and at least one curing lamp 24 is installed in each light box 21 for photocuring the product to be cured. A light-transmitting isolation member 23 is provided between the light box assembly 20 and the curing space, and the light-transmitting isolation member 23 is installed in a first open area on the light source side. The rotating member 22 is located on the light source side and connected to the curing chamber 10. The light box 21 is connected to its corresponding rotating member 22, such that the light box 21 rotates between a first closed position close to the light-transmitting isolation member 23 and a first open position away from the light-transmitting isolation member 23. Here, the product to be cured is a coated conduit. In other embodiments, the product to be cured can be other products.

[0026] In this embodiment, the curing lamp 24 can be repaired or replaced simply by rotating the lamp box 21, which is convenient to operate. Furthermore, when there are two lamp boxes 21, different lamp boxes can be rotated in two different directions to repair or replace the curing lamp 24 in both lamp boxes 21 at the same time, which can improve the efficiency of repair or replacement.

[0027] In some embodiments, there are two light boxes 21, which are respectively arranged on both sides of the rotating member 22 and connected to the rotating member 22. Both light boxes 21 are rotatable relative to the rotating member 22 and have a first closed position arranged side-by-side to shield the first open area and a first open position rotated by a preset angle to expose the curing lamp 24. Here, the two light boxes 21 can share a rotating member 22 or use a separate rotating member 22, depending on the design requirements. In some embodiments, the preset angle range is 30°-180°, for example, 30°, 45°, 60°, 80°, 100°, 120°, 150°, or 180°. In a preferred embodiment, the preset angle range is 45°-180°. Here, the preset angle can be designed according to specific design requirements, as long as the preset angle allows the light box 21 to expose the curing lamp 24.

[0028] In some embodiments, the rotating element 22 is a hinge. In this embodiment, there are multiple rotating elements 22, arranged at intervals along a vertical, horizontal, or diagonal path. In some embodiments, there are two hinges, located at the top and bottom of the light box 21, respectively. In other embodiments, the number of rotating elements 22 can be determined according to specific design requirements. The hinges can be double-row hinges.

[0029] In some embodiments, the light box 21 includes a first side plate 211, a second side plate 214, a top plate 212 and a bottom plate 213. The bottom plate 213 and the top plate 212 are respectively disposed at the bottom and top of the light box 21 along the vertical direction. The first side plate 211 and the second side plate 214 are arranged at intervals along the horizontal direction, and the top of each side plate 214 is connected to the top plate 212, and the bottom of each side plate 214 is connected to the bottom plate 213.

[0030] In some embodiments, the first side plate 211, the second side plate 214, the top plate 212, and the bottom plate 213 form a second open area 215, which faces the inside of the curing chamber 10 when the light box 21 is in the closed position. This can be understood as the light box 21 being open on only one side, and the curing lamp 24 curing the product to be cured from the open side of the light box 21.

[0031] In some embodiments, when the light box 21 is in the first closed position, the second open area 215 is arranged corresponding to the first open area, so that the light-transmitting isolation component 23 isolates the product to be cured and the curing lamp 24.

[0032] In some embodiments, the light-transmitting isolation component 23 is glass. In another embodiment, the light-transmitting isolation component 23 can also be replaced with other types of light-transmitting isolation components, such as PC, crystal, or transparent resin. The light source of the curing lamp 24 passes through the light-transmitting isolation component 23 to cure the product. In the prior art, the light-transmitting isolation component 23 is connected to the lamp box 21, so when repairing or replacing the curing lamp 24, it is necessary to first disassemble the light-transmitting isolation component 23 before repairing or replacing the curing lamp 24, thus posing a risk of damage to the light-transmitting isolation component 23 or the curing lamp 24. In this embodiment, the light-transmitting isolation component 23 is connected to the curing chamber 10. When the lamp box 21 is rotated, the light-transmitting isolation component 23 does not rotate with it, and the curing lamp 24 can be repaired or replaced directly without disassembling the light-transmitting isolation component 23, reducing the risk of damage to the curing lamp 24 or the light-transmitting isolation component 23.

[0033] In some embodiments, the curing chamber 10 also has a maintenance side, and the light curing device 100 further includes a maintenance door 30, which is installed on the maintenance side and can be switched between a second closed position and a second open position.

[0034] This embodiment adds a maintenance door 30 to the front of the curing chamber 10, providing a maintenance channel for subsequent inspection and commissioning. This facilitates maintenance personnel in easily replacing internal components of the curing chamber 10, and also makes it easier for them to debug the equipment, better identify and resolve related problems. In addition, maintenance personnel can also enter the curing chamber 10 through the maintenance door 30 to repair the light-transmitting isolation component 23, which is quite convenient, and also allows for regular cleaning of the interior of the curing chamber 10.

[0035] In some embodiments, each light box 21 is equipped with a plurality of curing lamps 24, which are arranged vertically at intervals. Each curing lamp 24 has its two sides corresponding to the first side plate 211 and the second side plate 214, respectively. The arrangement of the curing lamps 24 is determined according to the shape of the product to be cured. This embodiment is for curing a conduit, which is elongated and suspended vertically within the curing chamber 10. The plurality of vertically spaced curing lamps 24 can cure different parts of the conduit and achieve uniform curing. In this embodiment, each light box 21 is equipped with three curing lamps 24. In other embodiments, the number of curing lamps 24 can be determined according to specific design requirements.

[0036] In some embodiments, the side of the light box 21 away from the rotating member 22 is provided with at least one handle 216 for operation. The operator can operate the handle 216 to rotate the light box 21, which can improve the convenience of rotating the light box 21.

[0037] In some embodiments, the curing lamp 24 is a mercury lamp. In other embodiments, the curing lamp 24 may be other types of curing lamps, depending on the design requirements.

[0038] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
