Description

Technical Field

[0001] The present application relates to the field of test room access structures, and in particular to an operating window structure. Background Art

[0002] Chips must pass various electrical tests before leaving the factory. With different test purposes, there are different requirements for the test environment provided by the test machine. For example, some chips are expected to operate normally under extremely low temperature and extremely dry conditions. Therefore, the test machine must provide an independent and closed test room with relevant refrigeration and dehumidification equipment to maintain the test room in the required test environment for a long time for the chip to undergo various electrical tests in the test room.

[0003] During the test, it is inevitable that a fault or a protrusion may occur, which must be manually eliminated. Therefore, in the related art, the test chamber is generally provided with an operation window which is usually closed and opened only when necessary, so that a hand can reach into the test chamber to eliminate the fault.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: such operating windows usually only provide two modes: open / closed. Once opened, the indoor / outdoor spaces of the operating room are immediately connected to a greater extent, and the outdoor normal temperature will immediately affect the low temperature and dryness data in the test room. Therefore, after the fault is eliminated and the operating window is closed, it is usually necessary to wait for at least 10 to 20 minutes for the refrigeration and dehumidification equipment to operate before the original set conditions and temperature can be restored. That is, after the operation is completed, it is easy to waste too much waiting time, so it needs to be improved. Summary of the invention

[0005] In order to reduce the degree of communication between the indoor and outdoor spaces of the operating room during operation, the present application provides an operating window structure.

[0006] The present application provides an operating window structure that adopts the following technical solution: An operating window structure comprises a body provided with a window, wherein the window is provided with a plurality of blocking bars which cover the entire window.

[0007] By adopting the above technical solution, a number of baffles cover the entire window. During operation, the baffles can fit tightly against the operator's hands, significantly reducing the outflow of dry air or cold air from the window. In a simple way, the degree of communication between the indoor and outdoor spaces of the operating room during operation is reduced, and the time required for the operating room to be restored to the original set conditions and temperature through the operation of refrigeration and dehumidification equipment after the operation is completed is shortened, thereby increasing the occupancy time of the entire equipment pause cycle during the operation.

[0008] Preferably, the plurality of baffles are all conductive films, and the plurality of conductive films are all electrically connected to an electrostatic eliminator.

[0009] By adopting the above technical solution, the operator can immediately eliminate static electricity when his hand touches the conductive film, avoiding damage to the chip caused by static electricity, simplifying the static electricity elimination steps and further improving the operating efficiency.

[0010] Preferably, the window is provided with a metal strip, a plurality of the baffles are connected to the metal strip, and the static eliminator is electrically connected to the metal strip.

[0011] By adopting the above technical solution, the provision of the metal strip ensures the stability of the fixed end of the conductive film and helps to effectively conduct static electricity, further improving the reliability and effect of static electricity elimination.

[0012] Preferably, the ends of the plurality of baffles on the same side are connected as one body.

[0013] By adopting the above technical solution, the ends of the same side of several baffles are connected as a whole, making the conductive film more convenient to produce and assemble, while ensuring a tight fit in an unstressed state to reduce the outflow of dry air or cold air.

[0014] Preferably, at least one end of each of the plurality of baffles is connected to the window via an elastic member.

[0015] By adopting the above technical solution, at least one end of a plurality of baffles is connected to the window through an elastic member, so that the baffles are tightly attached to each other under normal conditions. When the hand is inserted, the restoring force of the elastic member makes the baffles tightly attached to the hand, reducing the opening, effectively preventing dry air or cold air from flowing out, and ensuring the simultaneous realization of the static electricity elimination function.

[0016] Preferably, a connecting piece is provided at one end of the baffle bar close to the elastic member, and the connecting piece is connected to the elastic member.

[0017] By adopting the above technical solution, a connecting piece is provided at one end of the baffle bar close to the elastic member, and the connecting piece is used to clamp and fix the baffle bar in the entire width direction, and then the connecting piece is used to connect the baffle bar to the elastic member, thereby avoiding direct connection between the flexible baffle bar and the elastic member at a certain point, thereby extending the service life of the baffle bar during use.

[0018] Preferably, the window is provided with a baffle, and the baffle is located on the side of the elastic member.

[0019] By adopting the above technical solution, the baffle arranged on the window is located on the side of the elastic member, which can further block the internal / external environment from communicating with the elastic member. The elastic member can also be covered by the baffle in the extended state, thereby further reducing the outflow of dry air or cold air and the exchange with the outdoor environment.

[0020] Preferably, the plurality of baffles are arranged parallel to each other.

[0021] By adopting the above technical solution, a plurality of baffles are arranged in parallel with each other, so that when the operating window is in normal use, the baffles are closely arranged, which can effectively reduce the outflow of dry air or cold air from the test room. At the same time, when the operator puts his hand in, the baffles can remain tightly fitted, further reducing air loss and improving the stability of the test environment.

[0022] Preferably, the plurality of baffles are divided into two layers, the plurality of baffles in each layer are arranged parallel to each other, and the baffles in the two layers are staggered in the projection direction.

[0023] By adopting the above technical solution, a number of baffles are divided into two layers, and a number of baffles in each layer are arranged parallel to each other, and the two layers of baffles are staggered in the projection direction, thereby further improving the sealing of the operating window structure, effectively reducing the outflow of dry air or cold air, and enhancing the fit of the operating window structure to the operator's hand, further reducing the exchange of internal / external environment, and also further improving the stability of the static elimination function.

[0024] Preferably, the window is slidably connected with an elastic retaining ring, and the elastic retaining ring is in contact with at least a portion of the retaining bar and is located on the outward side of the retaining bar.

[0025] By adopting the above technical solution, the elastic retaining ring is in fit with at least a portion of the retaining strip and is located on the outward side of the retaining strip, which can further reduce the outflow of dry air or cold air. The inner edge of the retaining ring is more closely fitted to the operator's hand, ensuring that the internal / external environment is minimized from communicating during operation, providing a better sealing effect.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The conductive films can be closely attached to each other at ordinary times to prevent dry air or cold air from flowing out. During operation, the elastic parts keep the conductive films close to the hands, effectively reducing the outflow of dry air or cold air; 2. The static eliminator is electrically connected to the conductive film. When the operator touches the conductive film, the static electricity on the body can be immediately eliminated, reducing the probability of chip damage caused by static electricity; 3. Fix one end of the conductive film by a metal strip, and maintain the stability of the conductive film after installation by an elastic member, so as to further improve the sealing effect and facilitate the conduction of static electricity.

DETAILED DESCRIPTION

[0029] The inventor of this application found that dry air or cold air easily flows out of the existing machine operation window during troubleshooting, and the operator easily forgets to eliminate static electricity, resulting in chip damage. To this end, this application mainly adopts the following technical solutions, which reduce the impact of dry air or cold air outflow by setting an operation window and its components on the inner wall of the machine side wall, and also simultaneously eliminate static electricity, effectively improving the test efficiency and quality.

[0030] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0031] An embodiment of the present application discloses an operating window structure.

[0032] Example 1 Reference Figure 1, an operation window structure is arranged on the test body 1 of the chip, and a plurality of side panels 11 are installed around the top of the body 1, and the plurality of side panels 11 cooperate with the top cover plate to enclose a test space. The side panel 11 is provided with a window 12 for manual entry and exit. An outer window 13 is arranged on the outer side of the side panel 11, and the outer window 13 is rotatably pivotally mounted on the outer side of the side panel 11 to seal the window 12 when manual operation is not required, and it will only be opened when troubleshooting is being performed or internal maintenance is required. In addition, the outer window 13 and the side panel 11 are made of transparent materials, which is convenient for seeing the operating status of the internal mechanism clearly during maintenance.

[0033] Reference Figure 2 A window frame 21 is fixedly arranged on the inner side of the side panel 11 at the periphery of the window 12. The window frame 21 surrounds the periphery of the window 12. A plurality of baffles 22 are arranged inside the window frame 21. The baffles 22 are parallel to each other and are vertically arranged so that the baffles 22 cover the enclosed area of ​​the window frame 21. The baffles 22 are located in the same plane in a normal state to seal the window 12, so that even when the outer window 13 is in an open state, the internal / external environments can be kept non-intercommunication or reduced in communication.

[0034] Reference Figure 2 and Figure 3 , the tops of several baffles 22 are integrally formed and the transverse strips formed at the top integrally formed are fixed to the window frame 21 through a metal strip 24 and bolts, so that several baffles 22 are curtain-shaped. An electrostatic eliminator 30 is also provided in the machine. The electrostatic eliminator 30 is electrically connected to the metal strip 24 through an electric wire 31. The metal strip 24 is made of a material with good conductive properties. Several baffles 22 are made of conductive films and are also made of conductive materials, which is conducive to the conduction of static electricity. The metal strip 24 can not only firmly fix the baffle 22, but also better conduct static electricity, ensuring that static electricity can be transmitted to the electrostatic eliminator 30 through the metal strip 24, thereby achieving the elimination of static electricity. When a person opens the gap between the two baffles 22 and enters the interior of the test room, the hand will definitely contact the baffle 22, and the static electricity of the hand can be immediately eliminated, eliminating the additional operation process that requires reminders of static electricity, and can reduce the probability of chip damage caused by static electricity in the hand.

[0035] Reference Figure 2 and Figure 3 The bottoms of the plurality of baffles 22 are elastically connected to the window frame 21 through the connecting piece 26 and the elastic member 23. The connecting piece 26 is made of a high-strength, wear-resistant material, and the width of the connecting piece 26 is consistent with that of the baffle 22, so that the forces at various locations in the width direction of the baffle 22 are more balanced during the process of displacement and other actions. The connecting piece 26 and the baffle 22 are connected by bolts and nuts. In this embodiment, a two-point fixing method is used.

[0036] Reference Figure 2 and Figure 3 The elastic member 23 is preferably a spring, and the spring is selected from materials with good elasticity and long fatigue life. In addition, a baffle 27 is also provided at the window frame 21, and the baffle 27 is transversely arranged and located at the side of the elastic member 23 to further isolate the internal / external environment at the elastic member 23.

[0037] Reference Figure 4 The bottom and top of the elastic member 23 are integrally formed with hooks 25, the bottom of the window frame 21 is provided with bolts for hanging the hooks 25, and the bottom of the connecting piece 26 is penetrated with a hanging hole 260 for hanging the hooks 25. The two ends of the elastic member 23 are fixed by hanging with the hooks 25, which is convenient for subsequent replacement after the spring is aged.

[0038] Reference Figure 5 The implementation principle of this embodiment is as follows: in normal state, adjacent baffles 22 are tightly together to form a closed barrier. When the operator puts his hand in, the conductive film can be tightly attached to the hand through the deformation of the baffle 22 itself and the elastic effect of the elastic member 23, reducing the cross-sectional area of ​​the entire window 12 communicating with the outside air, thereby effectively preventing the loss of dry air or cold air. In addition, the static eliminator 30 is connected to the metal pressure strip 24 through the wire 31, so that when the operator's hand touches the baffle 22, the static electricity is immediately eliminated, which improves the stability of the test environment and the efficiency of chip testing as a whole.

[0039] Example 2 Reference Figure 6 The difference between this embodiment and the first embodiment is that the arrangement of the blocking bars 22 is further optimized. In this embodiment, the blocking bars 22 are divided into two layers, and the blocking bars 22 in each layer are arranged parallel to each other, and the blocking bars 22 of the two layers are perpendicular to each other in the projection direction, that is, the blocking bars 22 of one layer are all arranged vertically, and the blocking bars 22 of the other layer are all arranged horizontally. When installing, the two layers of blocking bars 22 can be installed on the inner / outer sides of the window frame 21 respectively, so that installation / maintenance can be achieved separately.

[0040] The implementation principle of this embodiment is: in actual application, when the hand passes through the single-layer barrier bar 22, the surface of the barrier bar 22 bends to form a circular arc with a larger diameter, while the cross section of the human hand is close to a circular circle with a smaller diameter, so that the barrier bar 22 can only be tangent to the human hand. Figure 5 For example, only vertically arranged baffles 22 can easily form small gaps on the upper and lower sides of a person's hand. In this embodiment, two layers of inner and outer baffles 22 arranged in a staggered manner are used to further block the small gaps on the upper and lower sides, thereby further strengthening the sealing effect, while achieving a better or more stable static elimination function, and further improving the test efficiency and quality.

[0041] Example 3 Reference Figure 7 and Figure 8 The difference between this embodiment and the embodiments 1 and 2 is that an elastic retaining ring 4 is further provided on the outside of the window frame 21. The elastic retaining ring 4 includes a hard frame 41 and an elastic film 42 inside the frame 41. The elastic film 42 has a hole in the middle for a hand to pass through (the diameter of the hole is smaller than the diameter of an arm, and the hand has an interference fit with the hole when passing through). Specifically, in order to achieve the adjustable position of the elastic retaining ring 4, the outer side of the frame 41 is fixedly connected to the window frame 21 through an elastic rope 43. Under normal conditions, the elastic retaining ring 4 is located near the center of the window 12, and the position of the elastic retaining ring 4 can be moved automatically when necessary. A sponge ring 44 is fixed to the side of the frame 41 facing the baffle 22 in a detachable manner such as Velcro. The sponge ring 44 fits well with the baffle 22. On the one hand, the sponge ring 44 can be used to better fit the baffle 22 to isolate the internal / external environment. On the other hand, the sponge ring 44 can be used to brush the dust on the outer wall of the baffle 22 during the process of adjusting the position of the elastic baffle ring 4, thereby reducing the risk of dust on the outer surface of the baffle 22 being brought into the internal operating environment by hand.

[0042] The implementation principle of the third embodiment is: the smaller gap between the blocking bar 22 and the human hand is further blocked by the elastic film 42, thereby further improving the sealing effect.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
