Description

Technical Field

[0001] The invention relates to the technical field of semiconductor stackers, and in particular to a semiconductor stacker with an anti-falling mechanism. Background Art

[0002] In the semiconductor industry, a high-tech industry that requires high precision and safety, semiconductor stackers play a key role in warehouse automation. Their safe and stable operation is essential to maintaining the continuity of semiconductor production lines and product quality. Semiconductor materials and products are expensive, which further highlights the importance of safe and stable operation of semiconductor stackers, especially the lifting platform of semiconductor stackers. This core component must overcome the potential risks caused by frequent, high-intensity operations and complex environments when performing vertical handling tasks. The lifting platform relies on precision transmission devices such as synchronous belts to achieve stable lifting and lowering in order to accurately handle fragile goods such as semiconductor wafers and packaged products. However, under the combined effects of long-term operation and harsh environments, once the wear and breakage of transmission components such as synchronous belts occur, the lifting platform will fall out of control, causing serious consequences such as equipment damage, cargo loss, and even casualties.

[0003] In view of the above risks, the existing semiconductor stacker anti-fall mechanism often draws on the design ideas of the elevator safety system and adopts safety clamps as the main protective measure. The safety clamp quickly clamps on the guide rail through a mechanical device when it detects overspeed or uncontrolled descent, thereby preventing the lifting platform from falling further. However, although this design improves safety to a certain extent, it also exposes problems such as high production cost, complex structure, cumbersome installation and debugging, and difficulty in subsequent maintenance. Especially under the conditions of changeable storage environment and limited space, the applicability and reliability of existing anti-fall mechanisms face challenges. How to improve the design of the semiconductor stacker's anti-fall mechanism while ensuring safety, so as to improve the reliability and maintenance convenience of the equipment, is to meet the urgent needs of the modern semiconductor industry for efficiency and safety.

Beneficial Effects

[0015] 1. Compared with the prior art, the semiconductor stacker significantly improves the safety and reliability of the operation of the semiconductor stacker through the cooperation of the anti-fall mechanism, the deceleration trigger mechanism and the deceleration mechanism. When a fall occurs and the anti-fall mechanism has not yet achieved the anti-fall function, the deceleration trigger mechanism and the deceleration mechanism provide the necessary buffering and deceleration force for the equipment to fall, and also significantly increase the probability of the anti-fall plug being successfully inserted into the limit hole. Even in the most unfavorable circumstances, when the anti-fall plug fails to directly prevent the fall, the deceleration mechanism can provide additional safety protection, effectively slowing down the falling speed of the equipment, reducing the risk of accidents, and reducing customer losses.

[0016] 2. Compared with the prior art, the semiconductor stacker has an anti-fall block slidably embedded in the first sliding cavity of the anti-fall mechanism. The anti-fall block slides out through the first sliding cavity under the elastic action of the first power spring and is inserted into the limit hole to prevent falling, effectively preventing falling accidents caused by unexpected situations, and can respond quickly in emergency situations to prevent falling. The overall mechanical structure design is simple, the production technology difficulty is low, and it is easy to be mass-produced and applied in the semiconductor industry and even other industries.

[0017] 3. Compared with the prior art, when the synchronous belt of the semiconductor stacker breaks and falls, the anti-fall plug will quickly pop out through the first sliding cavity under the push of the first power spring, and the moving ball at the front end uses the rolling characteristics to significantly reduce the friction between the contact surface, thereby ensuring that the plug can be quickly and smoothly inserted into the limit hole on the semiconductor stacker frame, achieving instant anti-fall locking.

[0018] 4. Compared with the prior art, the semiconductor stacker has a specially arranged oblique groove under the anti-fall plug to form a precise mechanical match with the deceleration trigger mechanism. When the synchronous belt breaks and falls and the anti-fall plug has not been fully inserted into the limit hole, that is, it is in a non-fully locked state, the oblique groove provides a key condition for the intervention of the deceleration trigger mechanism. The deceleration trigger mechanism can use the rebound force of the compression spring group to accurately insert the rectangular groove into the oblique groove. The deceleration mechanism is activated through this mechanical match. The whole process responds quickly and immediately, and the overall design is simple and easy to implement, which is suitable for large-scale production and wide application in the semiconductor industry and even other industries.

[0019] 5. Compared with the prior art, the semiconductor stacker, the deceleration plug as the core component, the details of its plug-out end are particularly important. In order to ensure that the deceleration plug can be stably maintained at the predetermined position after completing its deceleration task, to prevent the rebound phenomenon caused by inertia or external factors, thereby ensuring the deceleration effect of the deceleration mechanism.

[0020] 6. Compared with the prior art, in order to further improve the safety and stability of the deceleration plug when in contact with the semiconductor stacker frame, the semiconductor stacker also has a rubber head specially arranged on the front side of the plug-in end of the deceleration plug. This rubber material has good elasticity and wear resistance, and can provide effective buffering for the semiconductor stacker frame at the moment of contact, reducing the impact force caused by direct collision. At the same time, the outer surface of the rubber head can also be designed with specific patterns or textures according to actual needs to further increase the friction with the surface of the semiconductor stacker frame. The size of the deceleration plug is designed to be larger than the size of the limit hole. This design detail ensures that the deceleration plug will not be accidentally inserted into the limit hole during normal operation.

[0021] 7. Compared with the prior art, the semiconductor stacker has four sets of counterweight guide wheels symmetrically arranged on both sides of the counterweight block. This design not only enhances the stability of the counterweight block in multi-dimensional space, but also effectively disperses the impact force during operation, reducing wear and vibration. In addition, the four sets of counterweight guide wheels are designed to be guide wheels with a centrifugal lock structure. When the counterweight block falls to a certain speed, the guide wheels are locked to prevent the guide wheels from rolling, turning rolling friction into sliding friction, thereby increasing friction and reducing the falling speed, further improving the safety and reliability of the semiconductor stacker.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figure 1-Figure 13The semiconductor stacker with anti-fall mechanism provided by the present invention comprises a stacker frame 1, wherein a plurality of limit holes 17 are provided at equal intervals in the longitudinal direction in the middle of the stacker frame 1, and the spacing of the limit holes 17 is 100 mm; a synchronous belt 2 is provided on the stacker frame 1, one end of the synchronous belt 2 is fixedly connected to a counterweight block 4 to balance the load, and the other end is connected to an upper response plate 3, and this design ensures the stability during the transmission process and the response speed when the synchronous belt 2 breaks. A first baffle plate 7 is provided in the middle of the front side of the upper response plate 3, and is fixedly connected to the upper end of the first baffle plate 7, and a response transmission assembly 5 is slidably connected to both sides below the upper response plate 3, and a lower response plate 6 is connected below the response transmission assembly 5, in order to quickly realize the fall response and anti-fall transmission. A lifting slide rail 1801 is provided on the left and right sides of the stacker frame 1, and a lifting buckle 1802 is embedded on the outer surface of the lifting slide rail 1801, and the lifting buckle 1802 is fixedly connected to the lower response plate 6. The lower response plate 6 is slidably connected to the stacker frame 1, and the anti-fall mechanism 8 and the deceleration mechanism 11 are longitudinally embedded in the middle of the front side of the lower response plate 6 in sequence, and a pop-up space 10 is opened in the interval area between the anti-fall mechanism 8 and the deceleration mechanism 11, and a deceleration trigger mechanism 9, a second baffle plate 12, and a compression spring group 19 are arranged inside the pop-up space 10, and the deceleration trigger mechanism 9 is fixedly connected to the second baffle plate 12; the second baffle plate 12 is elastically connected to the deceleration mechanism 11 through the compression spring group 19.

[0039] The anti-fall mechanism 8 includes a first fixed block 801, a first cover plate 805, a first power spring 806, and an anti-fall plug block 803; the first fixed block 801 serves as the basic frame of the entire anti-fall mechanism 8. The fixed block is made of high-strength material to ensure that it can maintain the stability of its shape and position when subjected to various external forces. A plurality of first fixing holes 809 are provided on the front side thereof for firmly mounting the mechanism on the stacker frame 1. A first sliding cavity 802 is provided in the middle of the first fixed block 801, and a rectangular groove 808 is provided below the first fixed block 801 and extends through the first sliding cavity 802; an anti-falling plug 803 is slidably embedded in the first sliding cavity 802, and the anti-falling plug 803 slides out through the first sliding cavity 802 under the elastic action of the first power spring 806, and is inserted into the limiting hole 17 to prevent falling, wherein the first sliding cavity 802 and the anti-falling plug 803 are both designed as T-shaped structures, which not only ensures the stability of the plug during the sliding process, but also prevents the risk of the plug accidentally falling off, and the plug-out end size of the anti-falling plug 803 is smaller than the size of the limiting hole 17. The anti-falling plug 803 is the core executive component of the anti-falling mechanism 8, and its rear side is closely connected to the first cover plate 805 through the first power spring 806. This elastic connection mechanism enables the anti-falling plug 803 to be ready to respond to possible falling risks at any time. When the synchronous belt 2 breaks and falls, the anti-fall plug 803 will quickly pop out through the first sliding cavity 802 under the push of the first power spring 806. The moving ball 804 at the front end uses the rolling characteristics to significantly reduce the friction between the contact surface, thereby ensuring that the plug can be quickly and smoothly inserted into the limit hole 17 on the stacker frame 1 to achieve instant anti-fall locking. An oblique groove 807 is specially set below the anti-fall plug 803. The width of the oblique groove 807 is not greater than the width of the rectangular groove 808. This design is intended to form a precise mechanical fit with the deceleration trigger mechanism 9. The oblique groove 807 provides a key condition for the intervention of the deceleration trigger mechanism 9. When the anti-fall plug 803 has not been fully inserted into the limit hole 17, that is, when it is in a non-fully locked state, the deceleration trigger mechanism 9 can use the rebound force of the compression spring group 19 to accurately insert the oblique groove 807 through the rectangular groove 808. This mechanical coordination not only activates the deceleration mechanism 11, providing the necessary buffering and deceleration force for the equipment to fall, but also significantly increases the probability of the anti-fall plug 803 being successfully inserted into the limit hole 17. Even in the most unfavorable situation, when the anti-fall plug 803 fails to directly prevent the fall, the deceleration mechanism 11 can provide additional safety protection, effectively slowing down the falling speed of the equipment and reducing the risk of accidents.

[0040] The response transmission assembly 5 includes a response spring 501, a guide shaft 502 and a spring limiting nut 503; the guide shaft 502 penetrates and slides to connect the upper response plate 3, and spring limiting nuts 503 are provided at both ends. The response spring 501 is sleeved on the guide shaft 502 and limited above the upper response plate 3. The lower end of the first baffle plate 7 is arranged in front of the anti-fall mechanism 8, including a first release groove 13 and a first limiting wall 14; the first release groove 13 is arranged above the first limiting wall 14. When the synchronous belt 2 is normally tensioned and running, the response spring 501 in the response transmission assembly 5 is in a compressed state under the upward pulling force of the upper response plate 3 and the gravity of the lower response plate 6, and at the same time drives the first baffle plate 7 to move upward so that the first limiting wall 14 contacts the front lower side of the anti-fall plug 803, and the height of the contact part is not greater than the transmission distance of the response transmission assembly 5, that is, the compression distance of the response spring 501. When the synchronous belt 2 breaks, the response spring 501 in the response transmission assembly 5 loses the compression force and rebounds quickly, and the corresponding first baffle plate 7 moves downward, so that the anti-fall plug 803 loses the blocking effect of the first limiting wall 14 and quickly pops out from the first release groove 13.

[0041] The deceleration mechanism 11 includes a second fixed block 1101, a second sliding cavity 1102, a limit spring group 1105, a T-shaped limit block 1106, a second cover plate 1107, a second power spring 1108, and a deceleration plug 1103; the second fixed block 1101 serves as the basic support of the entire deceleration mechanism 11, and its stability and precision are directly related to the realization of the deceleration effect. The fixed block is made of high-strength material to ensure that it can maintain the stability of its shape and position when subjected to various external forces. A plurality of second fixing holes 1109 are provided on the front side of the second fixed block 1101, which are used to securely mount the mechanism on the stacker frame 1. In the middle of the second fixed block 1101, a second sliding cavity 1102 is horizontally penetrated and opened. The second sliding cavity 1102 is in a T-shaped structure and has a smooth inner wall to minimize the friction resistance between the deceleration plug 1103 and the deceleration plug 1103. The deceleration plug 1103 is the core movable component in the deceleration mechanism 11. It is in the shape of a T-shaped structure and matches the sliding cavity, so that the plug can move forward and backward in the sliding cavity to perform the deceleration task. The rear side of the deceleration plug 1103 is tightly connected to the second cover plate 1107 through the second power spring 1108. The function of the second power spring 1108 is to provide an outward elastic force for the deceleration plug 1103. The second cover plate 1107 serves as the fixing point of the second power spring 1108 and is tightly fixedly connected to the rear side of the second fixed block 1101, providing a stable support structure for the entire deceleration mechanism 11. The second sliding cavity 1102 is transversely penetrated in the middle of the second fixed block 1101. The second sliding cavity 1102 is in a T-shaped structure, which ensures that the deceleration plug 1103 can slide smoothly therein and will not fall off. As a core component, the detailed processing of the plug-in end of the deceleration plug 1103 is particularly important. In order to ensure that the deceleration plug 1103 can be stably maintained at the predetermined position after completing its deceleration task and prevent the rebound phenomenon caused by inertia or external factors, a combination of a limit spring group 1105 and a T-shaped limit block 1106 is specially introduced as a limit mechanism. The limit spring group 1105 is in a compressed state in the initial state, that is, when the deceleration plug 1103 is not inserted, and is embedded in the insertion end of the deceleration plug 1103, and can provide sufficient elastic force for the T-shaped limit block 1106 without hindering the normal movement of the plug. When the deceleration plug 1103 extends outward due to external force and reaches a position in contact with the stacker frame 1, the limit spring group 1105 immediately enters the working state and applies an outward thrust to the T-shaped limit block 1106, so that the T-shaped limit block 1106 can respond quickly after the deceleration plug 1103 extends, and is firmly locked on the front side of the second fixed block 1101, thereby effectively preventing the rebound phenomenon of the deceleration plug 1103. In order to further improve the safety and stability of the reduction plug 1103 when in contact with the stacker frame 1 , a rubber head 1104 is specially provided on the front side of the insertion end of the reduction plug 1103 .This rubber material has good elasticity and wear resistance, and can provide effective buffering for the stacker frame 1 at the moment of contact, reducing the impact force caused by direct collision. At the same time, the outer surface of the rubber head 1104 can also be designed with specific patterns or textures according to actual needs to further increase the friction with the surface of the stacker frame 1. The size of the deceleration plug 1103 is designed to be larger than the size of the limit hole 17. This design detail ensures that the deceleration plug 1103 will not be accidentally inserted into the limit hole 17 during normal operation.

[0042] The deceleration trigger mechanism 9 includes an obtuse-angled plug block 901, a longitudinal slide rail 902, and a transverse slide rail 904 arranged perpendicular to the longitudinal slide rail 902; the obtuse-angled plug block 901 is a key component of the mechanism, and its obtuse-angled design matches the angle of the oblique groove 807 on the anti-falling plug block 803, ensuring that the plug block can be smoothly inserted into the oblique groove 807 during movement, thereby triggering the deceleration mechanism 11. The outer surface of the transverse slide rail 904 is embedded with a transverse buckle 905, and the transverse buckle 905 is fixedly connected to the obtuse-angled plug block 901; the outer surface of the longitudinal slide rail 902 is embedded with a longitudinal buckle 903, and the longitudinal buckle 903 is fixedly connected to the transverse slide rail 904; through the cooperation of the transverse slide rail 904 and the longitudinal slide rail 902, the obtuse-angled plug block 901 is provided with a motion track in the vertical and horizontal directions, so as to achieve stable contact between the obtuse-angled plug block 901 and the anti-falling plug block 803 and the insertion of the anti-falling plug block 803 into the oblique groove 807. One end of the longitudinal slide rail 902 is fixedly connected to the second baffle 12; the obtuse-angle plug 901 passes through the rectangular groove 808 and contacts the lower surface of the anti-fall plug 803; wherein, the width of the longitudinal slide rail 902 and the width of the obtuse-angle plug 901 are not greater than the width of the oblique groove 807.

[0043] The second baffle 12 is L-shaped; one side of the second baffle 12 is longitudinally arranged in front of the reduction mechanism 11, including a second release groove 16 and a second limiting wall 15; the second release groove 16 is arranged below the second limiting wall 15, and the second limiting wall 15 contacts the upper front of the reduction plug 1103, and the height of the contact part is not greater than the depth of the oblique groove 807, and is not less than half the depth of the oblique groove 807; the other side of the second baffle 12 transversely penetrates into the pop-up space 10, and is elastically connected to the reduction mechanism 11 through the compression spring group 19. When the synchronous belt 2 breaks, the anti-fall plug 803 responds quickly and is inserted into the limit hole 17. Due to the fast response speed of the anti-fall plug 803, the oblique groove 807 quickly passes through the rectangular groove 808, so that the obtuse plug 901 is not inserted into the oblique groove 807. At this time, the compression spring group 19 is always in a compressed state, and the second limit wall 15 contacts the front upper part of the deceleration plug 1103 to prevent the deceleration plug 1103 from popping out, that is, the deceleration mechanism 11 is not triggered. When the anti-fall plug 803 is not inserted into the limit hole 17, the anti-fall plug 803 vibrates back and forth between the limit hole 17 and the stacker frame 1, thereby causing the oblique groove 807 to move back and forth between the rectangular groove 808, increasing the probability of the obtuse plug 901 inserting into the oblique groove 807. When the obtuse-angle plug 901 is inserted to a depth at least half of the oblique groove 807, the second baffle 12 moves upward under the rebound action of the compression spring assembly 19, so that the deceleration plug 1103 loses the blocking effect of the second limiting wall 15, quickly pops out from the second release groove 16 and contacts the stacker frame 1, thereby achieving a deceleration effect.

[0044] The first counterweight guide wheel 401, the second counterweight guide wheel 402, the third counterweight guide wheel 403, and the fourth counterweight guide wheel 404 are symmetrically arranged on both sides of the counterweight block 4. The second counterweight guide wheel 402 and the third counterweight guide wheel 403 are perpendicular to the first counterweight guide wheel 401 and the fourth counterweight guide wheel 404. This design not only enhances the stability of the counterweight block 4 in multi-dimensional space, but also effectively disperses the impact force during operation, and reduces wear and vibration. Among them, the first counterweight guide wheel 401, the second counterweight guide wheel 402, the third counterweight guide wheel 403, and the fourth counterweight guide wheel 404 are one of the guide wheels with a centrifugal force lock structure. When the counterweight block 4 falls to a certain speed, the guide wheel is locked to prevent the guide wheel from rolling, and the rolling friction is converted into sliding friction, so as to increase the friction force and reduce the falling speed, further improving the safety and reliability of the stacker.

[0045] The present invention can be explained by the following operation mode:

[0046] When the synchronous belt 2 on the stacker frame 1 is tensioned and operating normally, the response spring 501 in the response transmission assembly 5 is in a compressed state under the upward pulling force of the upper response plate 3 and the gravity of the lower response plate 6, and at the same time drives the first baffle plate 7 to move upward so that the first limiting wall 14 contacts the front lower part of the anti-fall plug 803, preventing the anti-fall plug 803 from popping out. At the same time, one side of the second baffle plate 12 is longitudinally arranged in front of the deceleration mechanism 11, and the second limiting wall 15 contacts the front upper part of the deceleration plug 1103, preventing the deceleration plug 1103 from popping out. At this time, the anti-fall mechanism, the deceleration trigger mechanism 9 and the deceleration mechanism 11 are all in an inactive state.

[0047] When the synchronous belt 2 on the stacker frame 1 breaks, the response spring 501 in the response transmission assembly 5 loses the compressive force and rebounds quickly, and the corresponding first baffle 7 moves downward, so that the anti-fall plug 803 loses the blocking effect of the first limiting wall 14, and then quickly pops out from the first release groove 13 through the first sliding cavity 802 under the push of the first power spring 806, and quickly and smoothly inserts into the limiting hole 17 on the stacker frame 1. Due to the fast response speed of the anti-fall plug 803, the oblique groove 807 quickly passes through the rectangular groove 808, so that the obtuse-angle plug 901 in the deceleration trigger mechanism 9 is not inserted into the half of the oblique groove 807 or is not inserted into the oblique groove 807, then the second limiting wall 15 is always in contact with the front upper part of the deceleration plug 1103 to prevent the deceleration plug 1103 from popping out. That is, when the deceleration mechanism 11 is not triggered, the instant anti-fall locking is successfully achieved. At this time, the anti-fall mechanism and the deceleration trigger mechanism 9 are activated, but the deceleration mechanism 11 is in an unactivated state.

[0048] When the synchronous belt 2 on the stacker frame 1 is broken and the anti-falling plug 803 has not been fully inserted into the limiting hole 17, that is, it is in a non-fully locked state, the anti-falling plug 803 vibrates back and forth between the limiting hole 17 and the stacker frame 1, causing the oblique groove 807 to move back and forth between the rectangular groove 808, increasing the probability of the obtuse plug 901 being inserted into the oblique groove 807. The obtuse plug 901 in the deceleration trigger mechanism 9 cooperates with the transverse slide rail 904 and the longitudinal slide rail 902, and uses the rebound force of the compression spring group 19 to make the obtuse plug 901 inserted to at least half of the oblique groove 807. Under the rebound effect of the compression spring group 19, the second baffle 12 moves upward, so that the deceleration plug 1103 loses the blocking effect of the second limiting wall 15, and then quickly pops out from the second release groove 16 and contacts the stacker frame 1. At this time, the limit spring group 1105 immediately enters the working state, applying an outward thrust to the T-shaped limit block 1106, so that the T-shaped limit block 1106 can respond quickly after the deceleration plug 1103 is extended, and is firmly locked on the front side of the second fixed block 1101, thereby effectively preventing the rebound phenomenon of the deceleration plug 1103. The rubber head 1104 on the front side of the plug-in end of the deceleration plug 1103 can provide an effective buffering effect for the stacker frame 1 at the moment of contact. At the same time, the specific texture on the outer surface of the rubber head 1104 increases the friction with the surface of the stacker frame 1, thereby achieving the deceleration effect. In the deceleration state, the anti-fall plug 803 can be accurately inserted into the limit hole 17 with a greater probability, thereby achieving anti-fall locking. At this time, the anti-fall mechanism, the deceleration trigger mechanism 9 and the deceleration mechanism 11 are all in an activated state.

[0049] When the synchronous belt breaks, when the counterweight 4 falls to a certain speed, the guide wheel is locked under the action of the centrifugal force lock structure, and the rolling friction is converted into sliding friction to increase the friction force and reduce the falling speed. It should be noted that the first counterweight guide wheel 401, the second counterweight guide wheel 402, the third counterweight guide wheel 403, and the fourth counterweight guide wheel 404 are guide wheels with a centrifugal force lock structure. The guide wheel with a centrifugal force lock structure adopts the centrifugal force lock structure of the safety belt.

[0050] In addition, the stacker with the anti-fall mechanism 8 provided by the present invention can be provided with multiple anti-fall mechanisms 8 to increase the probability of the anti-fall plug 803 being inserted into the limit hole 17. And the deceleration mechanism 11 can be provided above, below, and on both sides of the anti-fall mechanism 8. When the anti-fall plug 803 is not immediately inserted into the limit hole 17, the friction force is increased by the response of the multi-directional deceleration mechanism 11 to further achieve the deceleration effect, thereby increasing the probability of the anti-fall plug 803 being inserted into the limit hole 17, and improving the safety and reliability of the stacker.

[0051] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
