Description

Technical Field

[0001] This utility model relates to a lamp, and more particularly to a multi-purpose UV lamp. Background Technology

[0002] Currently, many industries use UV-curable adhesives for product bonding. UV-curable adhesives require UV lamp irradiation during bonding. Common UV lamps typically consist of multiple LEDs mounted on a single plane. The diffused light emitted by these LEDs irradiates the product surface, causing the UV-curable adhesive to solidify and bond. With this type of UV lamp, the curing speed of the UV-curable adhesive is not significantly different when irradiating a plane directly opposite it. However, if the product has steps or grooves, the UV lamp cannot simultaneously irradiate all surfaces, resulting in varying light intensities on different surfaces. Consequently, the curing speed of the UV-curable adhesive varies at different locations on the product, affecting the bonding effect. Furthermore, it often requires irradiating surfaces in different directions separately, leading to a longer curing time. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a multi-purpose UV lamp that can simultaneously irradiate multiple surfaces of a target product, ensuring that the UV-curable adhesive at different locations on the target product solidifies synchronously, thereby improving bonding efficiency and bonding strength.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a multi-purpose UV lamp, including a light source carrier, a first light source, a second light source, and a conduit. The first light source is fixedly installed on the light source carrier and can emit light toward the surface of the target product. One end of the conduit is fixedly installed on the surface of the light source carrier facing the target product. The second light source is fixedly installed on the other end of the conduit. The other end of the conduit can be inserted into the groove structure of the target product. The light emitted by the second light source can illuminate the side wall of the groove structure of the target product or the side wall and bottom surface of the groove structure of the target product.

[0005] As a further improvement of this utility model, the conduit can convert all or part of the light emitted by the first light source into parallel light extending along its axis, and the parallel light can be emitted from the other end of the conduit and directly hit the bottom surface of the groove structure of the target product.

[0006] As a further improvement of this utility model, a focusing device is also provided. One end of the focusing device is fixedly installed on the surface of the light source carrier facing the target product, and one end of the conduit is fixedly installed on the other end of the focusing device. The focusing device can concentrate all or part of the light emitted by the first light source to form a concentrated beam. The concentrated beam formed by the focusing device can be guided by the conduit and irradiate the bottom surface of the groove structure of the target product.

[0007] As a further improvement of this utility model, the focusing device is a focusing lens, and the light emitted by the first light source is refracted and focused by the focusing lens to form a parallel beam of light that is uniformly distributed in the light guide tube.

[0008] As a further improvement of this utility model, the focusing device is a bowl-shaped focusing cover. The end of the focusing cover with a larger diameter is fixedly connected to one end of the light source carrier, and the end of the focusing cover with a smaller diameter is fixedly connected to one end of the guide tube. The light emitted by the first light source is reflected and focused by the reflective surface inside the focusing cover to form a beam of parallel light that is evenly distributed inside the light guide tube.

[0009] As a further improvement of this utility model, the first light source is a surface light source disposed on the end of the light source carrier facing the target product. The first light source emits parallel light or divergent light towards the surface of the target product. The second light source is a ring light source or a point light source. The ring light source is fixedly sleeved on the outer circumference of the other end of the conduit. Several point light sources are evenly spaced along the circumference of the conduit and fixedly installed on the outer circumference of the other end of the conduit.

[0010] As a further improvement of this utility model, the light source carrier is a box structure, and the first light source is fixedly installed on the inner side of the end of the box structure facing the target product. A light-transmitting part is formed on the end face of the box structure facing the target product for the light from the first light source to be emitted.

[0011] As a further improvement of this utility model, the side wall of the box structure is provided with a heat dissipation air inlet. A heat sink, a heat dissipation module and a fan are also fixedly installed inside the box structure. The heat sink is flat against the backlight surface of the first light source. The fan can exhaust the gas inside the box to the outside of the box structure. The heat dissipation module is sandwiched between the fan and the heat sink. A heat dissipation channel is formed on the heat dissipation module. The cold air entering through the heat dissipation air inlet can exchange heat with the heat sink in the heat dissipation channel and finally be exhausted to the outside of the box structure by the fan.

[0012] As a further improvement of this utility model, the heat sink has a clearance opening that is directly connected to the conduit. The conduit is a cylindrical structure with openings at both ends. Outside cold air can pass sequentially through the inner hole of the conduit, the clearance opening of the heat sink, and the heat dissipation channel on the heat dissipation module, and finally be discharged to the outside of the box structure by the fan.

[0013] As a further improvement of this utility model, a control signal interface is provided on the surface of the housing structure. The control signal interface is electrically connected to the first light source, the second light source and the fan via wires. A controller is also provided. The controller can be connected to the control signal interface wires on the surface of the housing structure via wires, thereby realizing the control of the first light source, the second light source and the fan.

[0014] The beneficial effects of this utility model are as follows: This utility model irradiates the main surface of the target product with a first light source, and at the same time, it irradiates the groove structure (including the stepped structure) on the target product with a second light source. This allows all surfaces of the target product coated with UV-curable adhesive to be cured by light simultaneously, ensuring that the UV-curable adhesive on all surfaces of the target product cures at the same time. This ensures that the bonding strength of the UV-curable adhesive on the target product is uniform and consistent, ensuring good bonding effect, and that it is not easy to delaminate after long-term use. Moreover, it can achieve complete curing of the UV-curable adhesive on all surfaces of the target product in the shortest possible time, thereby improving bonding efficiency.

[0028] Example: A multi-purpose UV lamp includes a light source carrier 1, a first light source 2, a second light source 3, and a conduit 4. The first light source 2 is fixedly installed on the light source carrier 1 and can emit light toward the surface of the target product 5. One end of the conduit 4 is fixedly installed on the surface of the light source carrier 1 facing the target product 5. The second light source 3 is fixedly installed on the other end of the conduit 4. The other end of the conduit 4 can be inserted into the groove structure 51 of the target product 5. The light emitted by the second light source 3 can illuminate the side wall of the groove structure 51 of the target product 5 or the side wall and bottom surface of the groove structure 51 of the target product 5.

[0029] When curing the UV-cured adhesive on different heights and directions of the target product 5 with grooves or steps, it is only necessary to insert the conduit 4 into the groove structure 51 of the target product 5 (the lower part of the step). The light from the first light source 2 illuminates the surface of the target product 5 closest to the first light source 2. Since the second light source 3 is inserted into the groove structure 51 of the target product 5 along with the conduit 4, the second light source 3 can illuminate the side walls and bottom surface of the groove structure 51 of the target product 5. This allows for simultaneous UV curing of the adhesive-coated surface of the target product 5 and the adhesive-coated surface inside the groove structure 51 on this surface. This enables simultaneous UV curing of adhesive-coated surfaces at different heights and directions on the target product 5, with consistent UV intensity, ensuring that these surfaces can cure simultaneously. This guarantees a strong and stable bond of the UV-cured adhesive on the target product 5. Furthermore, since multiple surfaces are cured simultaneously, it avoids step-by-step UV curing of different surfaces, greatly improving the curing efficiency of the UV-cured adhesive on the target product 5.

[0030] The conduit 4 can convert all or part of the light emitted by the first light source 2 into parallel light extending along its axial direction. The parallel light can exit from the other end of the conduit 4 and directly illuminate the bottom surface of the groove structure 51 of the target product 5. The light emitted by the first light source 2 can illuminate the bottom surface of the groove of the target product 5 in a parallel light state along the conduit 4, realizing photocuring of the bottom surface of the groove structure 51 of the target product 5. When only the inside of the groove structure 51 on the target product 5 needs photocuring, the conduit 4 can guide all the light emitted by the first light source 2 to the bottom surface of the groove structure 51, realizing rapid curing of the bottom surface of the groove structure 51. When both the surface of the target product 5 and the inside of the groove structure 51 on it need photocuring, the conduit 4 can guide part of the light emitted by the first light source 2 to the bottom surface of the groove structure 51, realizing synchronous curing of the bottom surface of the groove structure 51 and the surface of the target product 5. This can avoid the situation where the bottom surface of the groove structure 51 is difficult to cure due to insufficient light illumination.

[0031] A focusing device 6 is also provided. One end of the focusing device 6 is fixedly installed on the surface of the light source carrier 1 facing the target product 5, and one end of the guide tube 4 is fixedly installed on the other end of the focusing device 6. The focusing device 6 can concentrate all or part of the light emitted by the first light source 2 to form a concentrated beam. The concentrated beam formed by the focusing device 6 can be guided by the guide tube 4 and irradiate the bottom surface of the groove structure 51 of the target product 5. By focusing part or all of the light emitted by the first light source 2 through the focusing device 6 and then irradiating the bottom surface of the groove structure 51, the light intensity of the bottom surface of the groove structure 51 can be improved, avoiding the weakening of light energy due to the large distance, ensuring sufficient light intensity on the bottom surface of the groove structure 51, and achieving synchronous curing with other surfaces.

[0032] The focusing device 6 is a focusing lens 61. The light emitted from the first light source 2 is refracted and focused by the focusing lens 61 to form a parallel beam of light that is uniformly distributed within the light guide tube. The focusing of the first light source 2 is achieved by utilizing the principle of lens refraction, and the focusing effect can be adjusted simply by adjusting the curvature of the lens as needed.

[0033] The focusing device 6 is a bowl-shaped focusing cover 62. The larger diameter end of the focusing cover 62 is fixedly connected to one end of the light source carrier 1, and the smaller diameter end of the focusing cover 62 is fixedly connected to one end of the guide tube 4. The light emitted by the first light source 2 is reflected and focused by the reflective surface inside the focusing cover 62 to form a parallel beam of light evenly distributed within the light guide tube. The focusing of the first light source 2 is achieved by utilizing the principle of specular reflection, and the focusing effect can be adjusted simply by adjusting the curvature of the focusing cover 62 as needed.

[0034] The first light source 2 is a surface light source located on the end of the light source carrier 1 facing the target product 5. The first light source 2 emits parallel or divergent light towards the surface of the target product 5. The second light source 3 is a ring light source or a point light source. The ring light source is fixedly sleeved on the outer circumference of the other end of the conduit 4. Several point light sources are evenly spaced and fixedly installed on the outer circumference of the other end of the conduit 4. The first light source 2 can be a surface light source formed by a matrix arrangement of several LEDs, or it can be formed in other ways. The second light source 3 can also be multiple LEDs, evenly spaced and attached to the outer circumference of the other end of the conduit 4. The second light source 3 can also be a ring-shaped lamp tube, sleeved on the outer circumference of the other end of the conduit 4.

[0035] The light source carrier 1 is a box structure. The first light source 2 is fixedly installed on the inner side of the end of the box structure facing the target product 5. A light-transmitting part is formed on the end face of the box structure facing the target product 5 for the light from the first light source 2 to be emitted. The light-transmitting part can be a hollow structure or a light-transmitting material plate 11 provided on the end face of the box structure facing the target product 5. The light-transmitting material plate can be a quartz glass plate, which has good light transmittance, high strength, and is not easily damaged.

[0036] The enclosure structure has a heat dissipation air inlet 12 on its side wall. A heat sink 7, a heat dissipation module 8, and a fan 9 are also fixedly installed inside the enclosure structure. The heat sink 7 is flat against the backlight surface of the first light source 2. The fan 9 can exhaust the gas inside the enclosure to the outside of the enclosure structure. The heat dissipation module 8 is sandwiched between the fan 9 and the heat sink 7, and a heat dissipation channel is formed on the heat dissipation module 8. The cold air entering through the heat dissipation air inlet 12 can exchange heat with the heat sink 7 in the heat dissipation channel and is finally exhausted to the outside of the enclosure structure by the fan 9. The fan 9 is installed in the enclosure structure at the end facing away from the target product 5 via a fan 9 bracket 10. The heat generated by the first light source 2 is transferred to the heat sink 7. While the fan 9 exhausts air to the outside of the enclosure structure, cold air enters from the heat dissipation air inlet 12 on the side wall of the enclosure structure and enters the heat dissipation channel of the heat dissipation module 8, carrying away the heat on the surface of the heat sink 7 in the form of hot air. This can improve the service life of the first light source 2 and prevent it from overheating and burning out.

[0037] The heat sink 7 has a clearance opening 71 that communicates directly with the conduit 4. The conduit 4 is a cylindrical structure with open ends. Outside cold air can sequentially pass through the inner hole of the conduit 4, the clearance opening 71 of the heat sink 7, and the heat dissipation channel on the heat dissipation module 8, and finally be discharged to the outside of the housing structure by the fan 9. The above structure creates a heat dissipation channel inside the conduit 4. When the fan 9 exhausts air outward, outside cold air enters the other end of the conduit 4 and enters the heat dissipation module 8 along the conduit 4 and the clearance opening 71 on the heat sink 7 for heat dissipation, thereby cooling the second light source 3.

[0038] The housing structure has a control signal interface 13 on its surface. This interface is electrically connected to the first light source 2, the second light source 3, and the fan 9 via wires. A controller is also provided, which connects to the control signal interface 13 via wires to control the first light source 2, the second light source 3, and the fan 9. The controller can control the start / stop, operating time, and power of the first and second light sources 2 and 3, as well as the start / stop and speed of the fan 9. The housing can also be equipped with a mounting mechanism for mounting the housing on a bracket or at a designated location.
