Description

Technical Field

[0001] This utility model relates to the field of probe workpiece performance testing technology, and in particular to a flip-top slow-closing type sealing cavity. Background Technology

[0002] In today's semiconductor and related electronics fields, probe stations play a crucial role as key equipment for electrical performance testing of electronic components such as chips and wafers. With continuous technological advancements, research into the performance of electronic components in extreme environments has become increasingly in-depth, with performance testing in low-temperature environments being particularly important. When inspecting workpieces, they need to be placed in a specially designed sealed chamber. To prevent frost formation inside the chamber, it is necessary to fill the chamber with dry gas to ensure the internal environment meets the testing requirements. However, the existing flip-top mechanism of the sealed chamber is prone to generating significant impact during the flipping process, which can damage the chamber itself, affect the probe workpiece placed inside, and potentially injure the operator's hands. Therefore, we propose a flip-top slow-closing sealed chamber. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a flip-top slow-closing type sealing cavity.

[0004] The technical solution of this utility model is as follows: A flip-top slow-closing sealing cavity includes a sealing box, a sealing cover on the top of the sealing box, a flip-top groove at one end of the sealing box and the sealing cover, a flip-top assembly in the flip-top groove, the flip-top assembly including a vertical plate and a cover plate, multiple sets of fastening bolts on the side of the vertical plate and the cover plate close to each other, two sets of hinges on the mounting end of the vertical plate and one side of the inner wall of the flip-top groove on the sealing box, mounting cavities on both sides of the inner wall of the flip-top groove on the sealing cover, a slow-closing assembly in the mounting cavity, the slow-closing assembly including a fixing block, an electric damping rod in the fixing block, a rubber head at the output end of the electric damping rod, and slow-closing frames on both sides of the vertical plate corresponding to the mounting cavity positions.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This utility model has a simple overall structure. The slow-descent component allows the flip-top assembly to open slowly and close stably. When the flip-top assembly is closed, the electric damping rod pushes the rubber head, causing it to abut against the inner side of one end of the slow-descent frame. This ensures the stability of the flip-top assembly when closed and prevents it from opening arbitrarily. When the flip-top assembly needs to be opened, the electric damping rod causes the rubber head to retract slowly, reducing the pressure on the slow-descent frame. This allows the operator to open the flip-top assembly slowly, reducing vibration and impact, and preventing the flip-top assembly from falling rapidly and causing injury to the operator's hands.

A viewing window 7 is provided on the sealing cover 2, and an installation groove is formed on the sealing cover 2. The mounting end of the viewing window 7 is fixedly connected to the installation groove. The viewing window 7 allows the operator to view the workpiece during inspection. Flip-top grooves 3 are formed at one end of both the sealing box 1 and the sealing cover 2, which are close to each other. The flip-top assembly 4 is provided inside the 3-section. The flip-top assembly 4 includes a vertical plate 41 and a cover plate 42. A mounting plate 8 is provided on one side of the cover plate 42. A second mounting groove is provided on the cover plate 42. The mounting end of the mounting plate 8 is fixedly connected to the inner wall of the second mounting groove. A handle groove 9 is provided on the mounting plate 8. A handle 10 is provided in the handle groove 9. The mounting end of the handle 10 is rotatably connected to the inner wall of the handle groove 9. The handle 10 is designed to be hidden. The handle 10 allows the operator to lift the cover plate 42, thereby facilitating the operator's opening and closing of the flip-top assembly 4. Multiple sets of fastening bolts 43 are provided on the side of the vertical plate 41 and the cover plate 42 close to each other. Both the vertical plate 41 and the cover plate 42 have mounting bolts 43. The mounting bolt 43 is installed corresponding to the mounting bolt hole and is threadedly connected to the mounting bolt hole. The mounting bolt 43 allows the cover plate 42 to be fixedly mounted on the upright plate 41. When the upright plate 41 and the cover plate 42 are assembled in the "L" shape via the mounting bolt 43, the upright plate 41 is tightly fitted to the inner wall of the flip-cover groove 3 on the sealing box 1, and the cover plate 42 is tightly fitted to the inner wall of the flip-cover groove 3 on the sealing cover 2. When the flip-cover assembly 4 is closed, the cavity formed by the sealing box 1 and the sealing cover 2 is sealed during the inspection operation. Two hinges 4 are provided on one side of the inner wall of the flip-cover groove 3 on the sealing box 1 at the mounting end of the upright plate 41. 4. One side of the hinge 44 is installed corresponding to the bottom side of the upright plate 41. One side of the hinge 44 is fixedly connected to the upright plate 41. The other side of the hinge 44 is installed corresponding to one side of the sealing box 1. The other side of the hinge 44 is fixedly connected to the sealing box 1. Sealing gaskets are provided on the outer periphery of the upright plate 41 and the cover plate 42 and the inner wall of the flip cover groove 3. When the flip cover assembly 4 is in the closed state, the sealing gaskets can ensure the stability of the sealing box 1 when it is in the sealed state. The flip cover assembly 4 is designed to facilitate the operator to put the workpiece to be tested into the sealing box 1 for performance testing. At the same time, it is also convenient for the operator to take out the workpiece after testing, which improves the testing efficiency of the workpiece.

[0020] The inner walls of the flip-top groove 3 on the sealing cover 2 are provided with mounting cavities 5 on both sides. A slow-descent component 6 is installed in each mounting cavity 5. The slow-descent component 6 includes a fixing block 61, the mounting end of which is installed corresponding to one side of the inner wall of the mounting cavity 5 and is fixedly connected to the inner wall of the mounting cavity 5. An electric damping rod 62 is installed inside the fixing block 61, the mounting end of which is installed corresponding to the inner wall of the fixing block 61. An assembly groove is provided on the fixing block 61, and the mounting end of the electric damping rod 62 is fixedly connected to the inner wall of the assembly groove. A rubber head 63 is provided at the output end of the electric damping rod 62, the mounting end of which is installed corresponding to the output end of the electric damping rod 62 and is fixedly connected to the output end of the electric damping rod 62. The rubber head 63 is made of rubber. Slow-descent frames 64 are provided on both sides of the upright plate 41 at positions corresponding to the mounting cavities 5. The descent frame 64 is arranged in an "L" shape. The mounting end of the descent frame 64 is installed corresponding to one side of the upright plate 41. The inner wall of the other side of the descent frame 64 corresponds to the bottom of the rubber head 63. When the flip-top assembly 4 is closed, the electric damping rod 62 pushes the rubber head 63, causing the rubber head 63 to abut against the inner side of one end of the descent frame 64. This ensures the stability of the flip-top assembly 4 when closed and prevents the flip-top assembly 4 from opening arbitrarily. When the flip-top assembly 4 needs to be opened, the electric damping rod 62 drives the rubber head 63 to slowly retract, reducing the pressure of the rubber head 63 against the descent frame 64. This allows the operator to open the flip-top assembly 4 slowly, reducing vibration and impact, and preventing the flip-top assembly 4 from falling directly and rapidly when opened, which could cause injury to the operator's hands.

[0021] In this embodiment, when the operator needs to test the performance of the workpiece, the operator first pulls the handle 10, causing the handle 10 to drive the upright plate 41 to flip through the mounting plate 8 and the cover plate 42. At this time, the upright plate 41 rotates through the hinge 44, which in turn drives the slow-descent frame 64 to move. At this time, the rubber head 63 abuts against one side of the slow-descent frame 64, and the electric damping rod 62 drives the rubber head 63 to slowly retract, thereby opening the upright plate 41 in a flipped and slow-descent manner. Then, the operator places the workpiece to be tested into the sealed box 1, and then the operator flips the cover assembly 4 to close it. At this time, the cover plate 42 drives the fastening bolt 43 to abut against the hinge 44, thereby ensuring the stability of the cover assembly 4 in the closed state.

[0022] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
