For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0045] like Figures 1 to 7 As shown: A manual mask box opener includes: a box 1 with a top opening, a cover plate 2 disposed on the top of the box 1, and a transmission assembly 3 disposed inside the box 1.
[0046] The cover plate 2 has a first through hole 21 in the middle, and the box body 1 has a second through hole 11 on one side;
[0047] The transmission assembly 3 includes an upper core 31, a gear assembly 32, a rotating shaft 33, and a handle 34;
[0048] The upper core 31 is located inside the first through hole 21 and is provided with a pin 311;
[0049] The gear assembly 32 is located on the inner bottom of the housing 1;
[0050] The rotating shaft 33 passes through the second through hole 11, with one end connected to the handle 34 and the other end connected to the gear assembly 32;
[0051] By rotating the handle 34, the rotating shaft 33 and the upper core 31 are rotated, thereby driving the upper core 31 and the pin 311 to rotate around the axis of the upper core 31, so as to unlock the SMIF box.
[0052] In use, simply turn the handle 34 to drive the rotating shaft 33, gear assembly 32, vertical core, and pin 311 to rotate around the axis of the upper core 31 to unlock the SMIF box. The SMIF box can be unlocked by manually turning the handle 34, which smoothly transmits power to the upper core 31 through the rotating shaft 33 and gear assembly 32, causing the pin 311 to rotate around its axis. The operation is intuitive and fast.
[0053] By setting up a combined structure of housing 1, cover plate 2 and transmission assembly 3, mechanical drive is achieved by using handle 34, rotating shaft 33 and gear assembly 32. No electrical system is required, the structure is simplified, manufacturing and maintenance costs are reduced, and reliability is improved.
[0054] The transmission action can be completed by manually turning the handle 34, which drives the upper core 31 and its pin 311 to rotate, thereby unlocking the SMIF box. It is particularly suitable for occasions where the electrical environment is limited or the box needs to be opened temporarily. It is flexible in operation and highly adaptable.
[0055] The upper core 31 and the pin 311 work together to ensure that the pin 311 rotates accurately along the axis and cooperates precisely with the unlocking mechanism of the SMIF box, reducing jamming caused by offset or uneven force and improving the stability of the unlocking process.
[0056] Because it adopts a purely mechanical transmission method, it avoids abnormal mask opening problems caused by electrical component failures or network instability, effectively reducing the risk of mask damage or particle contamination, and improving the overall safety and reliability of use. This invention can be applied to small and medium-sized production lines, as well as laboratories or maintenance environments, combining flexibility and reliability, and expanding the application scenarios of mask openers.
[0057] As a preferred embodiment of the above, the gear assembly 32 includes a gearbox 321, a first bevel gear 322 and a second bevel gear 323 disposed in the gearbox 321 and meshing perpendicularly with each other, and a first bearing 324, a second bearing 325 and a third bearing 326 respectively disposed on both sides and the top of the gearbox 321.
[0058] A connecting rod 312 is provided at the bottom of the upper core 31. The connecting rod 312 passes through the third bearing 326 and is connected to the second bevel gear 323.
[0059] The rotating shaft 33 passes through the first bearing 324 and the second bearing 325, and the first bevel gear 322 is mounted on the rotating shaft 33 and rotates along the rotating shaft 33.
[0060] By setting a first bevel gear 322 and a second bevel gear 323 that mesh perpendicularly within the gearbox 321, the rotation of the rotating shaft 33 can be smoothly and reliably transmitted to the upper core 31, ensuring the synchronicity and accuracy of the pin 311's rotation, thereby improving the success rate of unlocking the SMIF box. By setting a first bearing 324, a second bearing 325, and a third bearing 326 on both sides and the top of the gearbox 321 respectively, a three-point support structure is formed for the rotating shaft 33 and the connecting rod 312, which greatly improves the stability of the transmission process and avoids gear meshing deviation caused by shaft wobbling.
[0061] In this embodiment, the transmission assembly 3 further includes a limiting rod 35 arranged in the direction perpendicular to the axis of the rotating shaft 33, and the limiting rod 35 is arranged at an inclination relative to the bottom of the housing 1.
[0062] The support rod 36 and the buckle 37 are located at the bottom of the housing 1 and on both sides of the rotating shaft 33. The buckle 37 is used to lock and position the rotating limit rod 35.
[0063] Additionally, a hook spring 38 connects the end of the limiting rod 35 and the end of the support rod 36 to achieve a reset function after the limiting rod 35 is moved.
[0064] During the rotation of the rotating shaft 33, the limiting rod 35 on the rotating shaft 33 is driven to move to the latch 37, so that the limiting rod 35 is engaged in the latch 37, locking the unlocked limit at the latch 37; thereby reliably locking the unlocked state, preventing accidental reset caused by reverse rotation, and ensuring the stability and safety of the SMIF box in the unlocked state.
[0065] Reverse rotation of the rotating shaft 33 resets the hook spring 38, causing the rotating shaft 33 to rotate and reset as well. By setting the hook spring 38 between the limiting rod 35 and the support rod 36, the limiting rod 35 can automatically reset after disengaging from the latch 37, thereby driving the rotating shaft 33 and handle 34 back to their initial positions. This makes operation easier and reduces manual intervention. Because the hook spring 38 provides auxiliary force during the reset process, the operator requires less torque when reversing the handle 34, improving the ease and comfort of manual operation.
[0066] The limiting rod 35 has a first ring structure 361 at its end and the support rod 36 has a second ring structure 351 at its end. The first ring structure 361 and the second ring structure 351 are used to hook the hook spring 38. Specifically, by setting ring structures at the ends of the limiting rod 35 and the support rod 36 respectively, the hook spring 38 can be quickly hooked or disassembled, simplifying the assembly and maintenance process and improving the ease of operation.
[0067] As a preferred embodiment of the above, the buckle 37 has a symmetrical bent shape, including a retaining section 371 in the middle and a guide section 372 located at one end of the retaining section 371. The retaining section 371 shrinks inward in the lateral direction, and the guide section 372 expands outward in the lateral direction.
[0068] When the limiting rod 35 rotates to the latch 37 position, the guide section 372 guides the limiting rod 35 into the holding section 371 and limits and positions the limiting rod 35 within the holding section 371. Specifically, the shape of the holding section 371 can be an arc segment, a V-shaped segment, or other shapes, all of which are within the protection scope of this application. The latch 37 has an inwardly contracting holding section 371 in the middle, which can provide a stable holding and positioning effect on the limiting rod 35, preventing the limiting rod 35 from loosening or falling out in the unlocked state, and improving the reliability after unlocking.
[0069] In this embodiment, a buffer post 39 is provided on the rotating shaft 33;
[0070] The housing 1 is also equipped with a damping assembly 4, including a base 41, a buffer sleeve 42, a buffer rod 43 and a buffer spring 44;
[0071] The base 41 is located on the inner side of the bottom of the housing 1. The buffer sleeve 42 is located on the base 41 and forms a receiving cavity. The buffer rod 43 passes through the buffer sleeve 42 and abuts against the buffer post 39. The buffer spring 44 is located in the buffer sleeve 42 and sleeved on the buffer rod 43. It is used to provide elastic damping when the buffer post 39 moves. Specifically, by setting the buffer post 39 on the rotating shaft 33 and using it in conjunction with the damping component 4, the instantaneous impact force generated by the rotating shaft 33 during rotation or reset is effectively absorbed, avoiding structural damage caused by excessive unlocking action.
[0072] Among them, the buffer post 39 has a flat section 391 at one end near the buffer post 39 to avoid local stress concentration caused by point contact, thereby improving the stability and durability of the buffer fit.
[0073] As a preferred embodiment of the above, a handle connector 341 is provided between the rotating shaft 33 and the handle 34;
[0074] The handle connector 341 has a cylindrical structure, including a first blind hole 341a and a second blind hole 341b that are perpendicular to each other. The first blind hole 341a is arranged along the length of the handle connector 341, and one end of the rotating shaft 33 is inserted into the first blind hole 341a. The end of the handle 34 is inserted into the second blind hole 341b. Specifically, the handle 34 and the connector, as well as the rotating shaft 33 and the connector, can be screwed, snapped, or inserted with a pin 311, all of which are within the protection scope of this application.
[0075] In this embodiment, a platform 5 is arranged side by side on one side of the box 1. The platform 5 is used to hold the lid of the SMIF box. Specifically, the platform 5 provides a dedicated holding position for the lid. The lid has a fixed temporary placement area, so the operator does not need to repeatedly search for or move it, saving operation time and improving overall work efficiency.
[0076] The bottom of the box 1 and the bottom of the platform 5 are provided with multiple support feet 12. The support feet 12 are used to support the box 1 and maintain the stability of the box 1 during placement. Specifically, the multiple support feet 12 are evenly distributed on the bottom of the box 1, which can adapt to the slight unevenness of different work surfaces or ground, and ensure that the device can be placed stably in various usage environments.
