Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor testing equipment, in particular to a light cylinder device. Background Art

[0002] One of the key performance indicators of a light sensor chip is its sensitivity to light, specifically its ability to accurately sense and generate corresponding electrical signals in even the faintest light. Furthermore, light sensor chips differ from other chip packaging because they contain photodiodes on their front surfaces. Automated mass production testing also requires screening for light-sensing performance, ensuring unobstructed front-side diodes and maintaining test stability during mass production.

[0003] Currently, when testing photodiodes, they need to be exposed to different light sources and tested at different distances and intensities. The light source environment must be leak-proof and unobstructed. However, the upper surface of the chip on the existing test platform is flush with the lower surface of the light tube device. During the test, due to differences in chip thickness and tolerance differences between structural components, light will scatter from the contact interface, affecting the test results. In addition, the existing light tube is installed and reinforced with screws, which makes it inflexible during multi-station installation and requires frequent screw tightening, which is also inefficient. Therefore, a light tube device is provided to solve the above problems. Utility Model Content

There are two connecting rods 8 symmetrically distributed, and a threaded hole is provided on the inner side of the front end of the connecting rod 8, which is convenient for assembling the T-shaped rod 7 and the L-shaped plate 101 with screws.

[0026] As an optional implementation in this embodiment, Figure 1 and Figure 5As shown, the cylinder assembly 6 includes a sleeve 601, an inner cylinder 602, a cover 603, a standard illuminant 604, a light-dotting plate 605, a light-blocking disc 606, a locking groove 607 and a stop screw 608. The inner side of the upper end of the sleeve 601 is provided with an inner cylinder 602, and the upper end of the inner cylinder 602 is provided with a cover 603. The cover 603 and the inner cylinder 602 are reinforced by fixing screws. The interior of the inner cylinder 602 is provided with a standard illuminant 604, wherein, since the standard illuminant 604 is an existing known technology, it will not be elaborated on in this specification. The inner side of the lower end of the inner cylinder 602 is provided with a light-dotting plate 605, and the light-dotting plate 605 is embedded and installed in the inner cylinder 602. On the inner side of the lower end, it is fixed with two internal screws to prevent it from falling off during use. A blocking disc 606 is provided below the outer end of the sleeve 601. There are two blocking discs 606 distributed above and below, and the arc-shaped shielding surfaces of the two blocking discs 606 are installed facing downward. Locking grooves 607 are provided on the left and right sides of the outer end of the sleeve 601, and stop screws 608 are provided on the left and right sides of the outer end of the inner cylinder 602.

[0027] Through the design of the upper and lower blocking optical discs 606, and the arc-shaped shielding surfaces of the two blocking optical discs 606 are facing downward, during operation, the blocking optical disc 606 docked at the bottom can form an arc-shaped shielding surface at the bottom of the sleeve 601, thereby shielding the chip placement area, and the blocking optical disc 606 sleeved at the top is installed above the locking groove 607 of the sleeve 601. When the distance between the inner cylinder 602 and the chip placement area below is adjusted, an arc-shaped shielding surface can be formed on the outside of the locking groove 607 to prevent side light leakage during testing. At the same time, in conjunction with the design of the cover plate 603, the top of the inner cylinder 602 can be closed to prevent light leakage from above when the standard light source 604 is working. By blocking from the top, bottom and sides of the light cylinder, light leakage during testing can be effectively reduced.

The middle part of the front end of the L-shaped plate 101 is provided with an arcuate groove 102, and sockets 103 are provided on the left and right sides of the arcuate groove 102. The rear side of the arcuate groove 102 is provided with a square groove 104, and the middle part of the rear end of the L-shaped plate 101 is provided with a tube groove 105; the pneumatic assembly 2 includes a shell 201, a piston cylinder 202, a fixing block 203, an air inlet pipe 204 and a piston rod 205. The interior of the shell 201 is provided with a piston cylinder 202, the outer side of the rear end of the shell 201 is provided with a fixing block 203, the middle part of the rear end of the piston cylinder 202 is provided with an air inlet pipe 204, and the piston cylinder 202 is provided with a fixing block 203. A piston rod 205 is provided in the middle of the front end. Since the structures and specific working methods of the piston cylinder 202 and the piston rod 205 are existing well-known technologies, they will not be elaborated on in this manual; the swing assembly 4 includes a swing arm 401, a clamping arm 402 and a latch 403. The front end of the swing arm 401 is provided with a clamping arm 402, wherein the swing arm 401 and the clamping arm 402 are spliced ​​into an integrated structure, and the contact end is reinforced by a fixing screw, and a card slot is provided on the inner side of the rear end of the swing arm 401 and the inner side of the front end of the clamping arm 402, and a latch 403 is provided above the front end of the swing arm 401, and there are two swing arms 401, clamping arms 402 and latches 403 symmetrically distributed.

[0029] By means of the provided L-shaped plate 101, when the light tube needs to be fixed, the inner tube 602 of the light tube is first placed in the arc groove 102, and then the piston tube 202 in the pneumatic assembly 2 cooperates with the piston rod 205 to move backward, pulling the push rod 3 to move backward, driving the rear ends of the swing arms 401 on both sides to expand outward, and the two clamping arms 402 at the front ends of the swing arms 401 on both sides will shrink inward, press against the clamping block 5 to tighten inward, clamping and fixing the outer wall of the inner tube 602, and when the light tube needs to be disassembled, it is only necessary to reverse the above operation to allow the clamping block 5 to be detached from the outer wall of the inner tube 602, thereby quickly removing the light tube. Compared with the traditional method of fixing by screws, it is more flexible, and the efficiency of installation and disassembly is also faster.

[0030] The working principle of the present invention is as follows: when the light cylinder device needs to be fixed, the inner cylinder 602 of the light cylinder is first placed in the arc groove 102, and then the piston cylinder 202 cooperates with the piston rod 205 to move backward, pulling the push rod 3 to move backward, driving the swing arms 401 on both sides to expand outward, and the two clamping arms 402 at the front ends of the swing arms 401 on both sides will shrink inward, press against the clamping block 5 to tighten inward, clamping and fixing the outer wall of the inner cylinder 602. When it is necessary to disassemble it later, it is only necessary to reverse the above operation to allow the clamping block 5 to detach from the outer wall of the inner cylinder 602. This allows the light tube to be quickly removed, which is more flexible than the traditional method of fixing with screws, and the efficiency of installation and removal is also faster. Secondly, through the upper and lower designs of the blocking optical disc 606, when working, an arc-shaped shielding surface can be formed under the sleeve 601 and on the outside of the locking groove 607. At the same time, the top of the inner tube 602 is closed in conjunction with the cover plate 603. When the anti-standard illuminant 604 is working, the chip placement area and the side of the light tube are shielded, and the top is closed, so that the light tube device can effectively reduce light leakage during testing when it is working, thereby ensuring the quality of the light source.
