Description

Technical Field

[0001] The utility model belongs to the field of optical machinery, and in particular relates to a xenon lamp fixing device. Background Art

[0002] Xenon lamps have excellent luminous properties, such as high brightness, wide wavelength, excellent arc stability, and low cost. Therefore, they are often used as illumination, reference, and measurement sources for optical instruments within semiconductor equipment. Due to their short lifespan, most equipment requires lamp replacement every six months to a year. The wick's position must be kept constant between replacements to minimize the impact of luminous point deviation on the optical system. Therefore, xenon lamp fixtures must be easy to replace and offer high position repeatability. Since the majority of heat generated by xenon lamps is dissipated through the electrodes, the electrodes must function as electrical connections, bulb fixation, and heat dissipation devices. Xenon lamps have two electrodes, the cathode and the anode. Their positional accuracy is generally lower than that of the mechanical components that secure them. Therefore, rigidly securing both electrodes is not recommended, as this can easily cause the lamp glass to shatter. Furthermore, if the electrodes are rigidly secured, the resulting thermal deformation can also easily lead to glass shattering.

[0003] While some current xenon lamp fixing solutions have addressed the issues of thermal deformation and breakage, as well as quick disassembly, lamp replacement remains inconvenient. Furthermore, while flexible supports have been added to either the cathode or anode to address glass shattering, lamp replacement still requires disassembly of the anode and cathode fixtures. Furthermore, the flexible supports exert a significant bending moment on the xenon lamp glass. Furthermore, the heat dissipation design for the cathode and anode is inadequate. Consequently, a new type of fixture for the cathode and anode of xenon lamps is in demand. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides a xenon lamp electrode fixing device, through which not only the electrical connection of the xenon lamp is achieved, but also the lamp is easily replaced and the heat dissipation of the electrode end is enhanced.

[0006] base;

[0007] An anode clamp, which connects the xenon lamp anode to the lamp holder. The bottom of the anode clamp is provided with a cylindrical hole for electrical connection to the xenon lamp anode. The top of the anode clamp is provided with a heat dissipation fin for heat dissipation at the anode end of the xenon lamp.

[0012] The cathode clamp module acts on the T-block through the screw and the first compression spring, exerting a radial force on the cathode, so that the cathode clamp and the T-block exert a flexible clamping force on the cathode.

[0013] In another embodiment of the present invention, it is provided that the flexible support module includes:

[0014] A cross shaft configured to apply a flexible force to the cathode axially, wherein a shoulder is provided in the middle of the cross shaft, the diameter of the shoulder is larger than the diameter of the two ends of the xenon lamp, and the bottom of the cross shaft is configured to cooperate with the cylindrical hole of the base; and

[0015] The second compression spring is configured to be sleeved on the bottom of the cross shaft to support the shaft shoulder, the second compression spring is arranged between the cross shaft and the cylindrical hole of the base, and the top of the cross shaft is configured to be inserted into the cathode center hole.

[0016] In another embodiment of the present invention, it is provided that the fixing flange surfaces of the anode clamp and the lamp holder are provided with pin positioning holes to ensure the position accuracy of the luminous point of the lamp wick before and after lamp replacement.

[0017] In another embodiment of the present invention, it is provided that the cathode clamp has heat dissipation fins with a smaller area than that of the anode clamp, so as to reduce the heat generated by the cathode.

[0018] In another embodiment of the present invention, it is provided that the top surfaces of the T-block and the cathode clamp, as well as the entrances of the mating surfaces thereof with the cathode, are all provided with chamfers.

[0019] In another embodiment of the present invention, it is provided that the matching holes between the base and the cross shaft, and the matching holes between the cross shaft and the cathode clamp are both coaxial with the anode.

[0020] In another embodiment of the present invention, it is provided that the lamp holder and the cross axis are made of insulating material.

[0021] In another embodiment of the present invention, it is provided that the cross shaft is configured to be able to slide freely axially in the matching hole of the base.

[0022] In another embodiment of the present invention, it is provided that the cross shaft and the cathode clamp are clearance-fitted, and the clearance of the clearance-fitted is configured to accommodate manufacturing coaxiality errors of the cathode and anode of the xenon lamp.

The appearances of the phrase "in one embodiment" in various places in this specification are not necessarily all referring to the same embodiment.

[0037] Figure 1 The figure shows a schematic structural diagram of a xenon lamp electrode fixing device in one embodiment of the present invention.

[0038] like Figure 1 As shown, in one embodiment of the present invention, the xenon lamp electrode fixing device includes: a base 1 , an anode clamp 2 , a cathode clamp module 3 , a lamp holder 4 and a flexible support module 5 .

[0039] The anode end of the xenon lamp is fixedly connected to the anode clamp 2, which is fixedly connected to the lamp holder 4. The lamp holder 4 is fixedly connected to the base 1. The lamp holder is approximately U-shaped, with a left arm and a right arm. The left arm is fixedly connected to the anode end of the xenon lamp, the right arm is flexibly connected to the cathode end of the xenon lamp, and the side is fixedly connected to the base 1.

[0040] Figure 2 A front view structural diagram of a xenon lamp electrode fixing device in one embodiment of the present invention is shown.

[0041] Combine Figure 2It can be seen that the flexible support module 5 includes: a second compression spring 502 and a cross shaft 501. The cross shaft 501 is configured to apply a flexible force to the cathode axially. A shoulder is provided in the middle of the cross shaft 501, and the shoulder diameter is larger than the diameter at both ends. The second compression spring 502 is configured to be sleeved on the bottom of the cross shaft to support the shoulder; the bottom of the cross shaft is configured to cooperate with the cylindrical hole of the base, and the second compression spring 502 is located between the two; the top of the cross shaft is configured to be inserted into the center hole of the cathode; in this way, the second compression spring presses against the base 1 and the cathode clamp 301, and the cross shaft 501 applies an axial pressure to the cathode clamp 301, and the cathode clamp 301 contacts the right arm of the lamp holder to form a radial friction force. The cathode clamp 301 bears both radial and axial forces, forming a stable and reliable flexible fixed state.

[0042] Figure 4 Shows a schematic structural diagram of the cathode clamp in one embodiment of the utility model.

[0043] like Figure 4 As shown, the cathode clamp module 3 includes: a cathode clamp 301, a T-block 302, a first compression spring 303, and a screw 304. An interface for accommodating the cathode and the T-block 302 is provided in the middle of the cathode clamp 301. The screw 304 and the first compression spring 303 act on the T-block 302 to apply a radial force to the cathode, so that the cathode clamp 301 and the T-block 302 can exert a flexible clamping force on the cathode.

[0044] Meanwhile, in one embodiment of the present invention, the cathode clamp 301 is equipped with heat dissipation fins of smaller area than the anode clamp 2 because the cathode generates less heat.

[0045] The top surfaces of the T-block 302 and cathode clamp 301, as well as the mating surface entrance of the cathode, are chamfered. To replace the lamp, simply loosen the fixed connection between the anode clamp 2 and the lamp holder 4 and remove the anode clamp 2 with the xenon lamp 6. There's no need to disassemble the cathode clamp module 3. The anode clamp 2 with the new xenon lamp 6 is directly inserted into the cathode clamp 301. The chamfers of the cathode clamp 301 and T-block 302 guide the cathode into the clamping surfaces of the cathode clamp 301 and T-block 302. Secure the anode clamp 2 to the lamp holder 4, and the lamp replacement is complete. This makes lamp replacement quick and easy.

[0046] Figure 5 The figure shows a schematic structural diagram of the anode clamp in one embodiment of the present invention.

[0047] A cylindrical hole 201 is provided at the bottom of the anode clamp 2, which can achieve electrical connection with the anode of the xenon lamp to power the xenon lamp 6; the top of the anode clamp is equipped with sufficient heat dissipation fins 202 to conduct a large amount of heat through the anode to the heat dissipation fins 202 to achieve heat dissipation at the anode end of the xenon lamp.

[0048] In one embodiment of the present invention, the matching holes between the base 1 and the cross shaft 501 , and the matching holes between the cross shaft 501 and the cathode clamp 301 are coaxial with the anode, and the cross shaft 501 is configured to be able to slide axially freely in the matching hole of the base 1 .

[0049] In one embodiment of the present invention, the cross shaft 501 and the cathode clamp 301 are clearance-fitted, for example, with a single-side clearance of 1 mm. This clearance is to accommodate manufacturing coaxiality errors between the cathode and anode of the xenon lamp. Other clearance values ​​are also contemplated in accordance with the present invention.

[0050] In one embodiment of the present invention, the fixing flange surfaces of the anode clamp 2 and the lamp holder 4 are provided with pin positioning holes 201 to ensure the positional accuracy of the luminous point of the wick before and after lamp replacement. The lamp holder and cross shaft are made of insulating materials such as ceramic, engineering plastics, and stone, which are not further limited by the present invention.

[0051] The following describes the steps for installation and application of this device:

[0052] The first step is to assemble the cathode clamp module. Insert the T-block into the matching position of the cathode clamp, use two screws and the first compression spring to penetrate the mounting hole 304 of the T-shaft, and fix the screws and the cathode clamp threads. The compression spring can flexibly pre-press the T-shaft on the cathode clamp. In this way, a set of cathode clamp modules is successfully assembled.

[0053] The second step is to install the cathode clamp module. Slowly insert the second compression spring from the bottom of the cross shaft until it hits the shaft shoulder. Insert the bottom of the cross shaft into the matching hole of the base, and then install the cathode clamp module to the matching shaft hole at the top of the cross shaft.

[0054] The third step is to fix the lamp holder and the base so that the end face of the right arm contacts the top of the cathode clamp. At this time, the installation and fixation of the lamp holder will compress the second compression spring for a certain distance, and the cathode clamp module has axial support force.

[0055] The fourth step is to insert the xenon lamp anode into the matching hole of the anode clamp and fix it. The cathode is inserted into the cathode clamp through the right arm of the lamp holder. A small radial alignment deviation is allowed during the insertion process. The chamfer on the top of the cathode clamp module will act as a guide, so that the cathode can be accurately inserted into the matching hole.

[0056] The fifth step is to fix the anode clamp to the lamp holder. The above steps complete the installation process of the xenon lamp device for the first use.

[0057] If you need to replace the light later, refer to step 6:

[0058] Step 6: To replace the lamp, loosen the fixed connection between the anode clamp and the lamp holder and directly pull out the anode clamp with the xenon lamp. There is no need to disassemble the cathode clamp module. The anode clamp with the new xenon lamp is directly inserted into the cathode clamp. The chamfered corners of the cathode clamp and T-block help the cathode enter the clamping surface of the cathode clamp and T-block. Secure the anode clamp and lamp holder to complete the lamp replacement operation. This makes lamp replacement very convenient and quick.

[0059] Although various embodiments of the present invention have been described above, it should be understood that they are presented as examples only and not as limitations. It will be apparent to those skilled in the relevant art that various combinations, modifications, and variations may be made thereto without departing from the spirit and scope of the present invention. Therefore, the breadth and scope of the present invention disclosed herein should not be limited by the exemplary embodiments disclosed above, but should be defined solely in accordance with the appended claims and their equivalents.
