Description

Technical Field

[0001] The utility model relates to the technical field of exposure machines, in particular to an exposure machine light source. Background Art

[0002] The exposure machine uses a high-pressure mercury lamp as a UV light source. The high-pressure mercury lamp uses two-pole arc discharge to atomize the mercury inside the lamp tube and emit UV light with a stable wavelength. However, the high-pressure mercury lamp is made of glass and there is a risk of breakage. Moreover, mercury is added inside the mercury lamp. If the high-pressure mercury lamp is broken, it will cause environmental pollution. At the same time, the high-pressure mercury lamp has a large power but low energy efficiency, resulting in energy waste.

[0003] Therefore, it is necessary to improve the traditional exposure machine light source to avoid the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an exposure machine light source to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An exposure machine light source includes a machine body. A vertical hole is opened on the machine body. The fixing rod at the bottom of the LED light source penetrates through the vertical hole, and a disc that abuts against the tabletop of the machine body is fixed on the fixing rod. The fixing rod is threadedly connected with a sleeve hole opened on a fixing sleeve. The LED light source is kept stable under the action of a limiting member.

[0007] Preferably, the limiting member includes an annular groove opened on the fixing sleeve, and the annular groove is slidably connected with a middle hole opened on a ring. A clamping rod is fixed on the ring, and the clamping rod penetrates through a through hole opened on the machine body and extends into a corresponding hole opened on the disc. A spring is also sleeved at the annular groove.

[0008] Preferably, one end of the spring is fixedly connected with the inner bottom wall of the annular groove, and the other end is fixedly connected with the bottom of the ring.

[0009] Preferably, multiple corresponding holes are circumferentially and equally angularly distributed on the disc.

[0010] Preferably, an elastic rubber gasket protrudes on the part of the fixing sleeve that abuts against the machine body.

[0011] Preferably, the LED light source only emits a wavelength of 365 nm and does not require a special metal-coated reflector for filtering.

[0012] In summary, due to adopting the above technical scheme, the beneficial effects of the utility model are as follows:

[0013] 1. This application reduces the production cost of lead frame products and improves the high-power problem of the high-pressure mercury lamp in the exposure machine. By introducing a new type of energy-saving LED light source, the power consumption during exposure is significantly reduced, the temperature near the light source decreases, and at the same time, by changing from a high-pressure mercury lamp to an LED lamp, the service life of the light source increases, the replacement frequency decreases, and the exposure production operation time is increased.

[0014] 2. The service life of the high-pressure mercury lamp in this application is 2,000 hours, and it needs to be replaced about 3.6 times a year. While the service life of the LED lamp is 10,000 hours, and it is expected to be replaced once every 4.8 years. Under the same exposure production conditions, an exposure machine with an LED light source can save 30,000 RMB in light source costs throughout the year. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Embodiment 1:

[0022] The present invention provides a technical solution. Please refer to Figures 1-3 :

[0023] An exposure machine light source includes a machine body 1. A vertical hole 2 is formed in the machine body 1. The fixing rod 5 at the bottom of the LED light source 4 penetrates through the vertical hole 2. A disc 6 that abuts against the tabletop of the machine body 1 is fixed on the fixing rod 5. The fixing rod 5 is threadedly connected to the sleeve hole 9 formed in the fixing sleeve 8. The LED light source 4 is kept stable under the action of the limiting member. An elastic rubber washer protrudes from the part of the fixing sleeve 8 that abuts against the machine body 1. The LED light source 4 only emits light with a wavelength of 365 nm and does not require a special metal-coated reflector for light filtering. The LED light source 4 does not require a special metal-coated reflector for light filtering. The LED light source 4 is only powered on and turned on during the exposure process, and is powered off and turned off after the exposure ends. Since the LED light source 4 can emit UV light with a stable wavelength and does not require UV light filtering, optical accessories such as integrators, folded aluminum mirrors, and cold reflectors are reduced, and the number of replacements of machine table accessories is reduced.

[0024] Embodiment 2:

[0025] Basically the same as the technical solution of Embodiment 1, the difference is that, as Figure 3 shown, the limiting member includes an annular groove 10 formed in the fixing sleeve 8, and the annular groove 10 is slidably connected to the middle hole 13 formed in the ring 12. A clamping rod 14 is fixed on the ring 12, and the clamping rod 14 penetrates through the through hole 3 formed in the machine body 1 and extends into the corresponding hole 7 formed in the disc 6. A spring 11 is also sleeved at the annular groove 10. One end of the spring 11 is fixedly connected to the inner bottom wall of the annular groove 10, and the other end abuts against the bottom of the ring 12. A plurality of corresponding holes 7 are circumferentially and equally angularly distributed on the disc 6. The clamping rod 14 penetrates through the through hole 3 and extends into different corresponding holes 7, which can adjust the angle of the LED light source 4, which is relatively convenient and fast.

[0026] In summary, when installing the LED light source 4 in this embodiment, the fixing rod 5 can be penetrated through the vertical hole 2 to adjust the position of the LED light source 4, and at this time the corresponding hole 7 is aligned with the through hole 3. Subsequently, the sleeve hole 9 of the fixing sleeve 8 can be threadedly connected to the fixing rod 5, and the clamping rod 14 is aligned with the through hole 3. Until the fixing sleeve 8 abuts against the bottom of the machine body 1, at this time the clamping rod 14 also penetrates through the through hole 3 and extends into the corresponding hole 7, that is, the fixing of the LED light source 4 to the machine body 1 is completed.

[0027] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
