Description

Technical Field

[0001] The utility model relates to the technical field of lifting mechanisms, in particular to an automatic lifting mechanism for a clean room. Background Art

[0002] A clean room refers to a low-temperature and dust-free environment, which can meet the use requirements of high-precision instruments for being sterile and dust-free. Thus, the automatic lifting mechanism in the clean room can ensure the sterile environment during the manufacturing process of medical devices. Through special design and strict cleaning procedures, efficient and accurate material handling can be carried out without damaging the clean room environment.

[0003] However, the automatic lifting mechanism needs to ensure that no air floating objects are generated, and its movement is relatively stable. It uses a pneumatic method as the power. When moving, it pushes the overall gravity to move. The movement of the track is prone to sliding friction, and then the ball bearings are subject to gravity friction to generate metal fines, which in turn affects the requirement of the lifting mechanism for a dust-free clean room and is prone to generate metal fines. Moreover, when the slide rail moves, the material needs to be lifted and moved, and then the center of gravity follows the movement. When the center of gravity moves, the movement of the slide rail is prone to drive the material to shake. When the material shakes, it is prone to generate a pulling force on the upper support sliding position in the reverse direction, thus causing the problem of unstable material movement.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the technical means, creative features, achieved purposes, and effects of the present utility model easy to understand, the preferred implementation schemes of the present utility model are further described below in conjunction with the specific implementation manners and the drawings. Embodiment

[0020] Please refer to Figures 1 - 5, the present utility model provides an automatic lifting mechanism for a clean room, and its structure includes a cross beam 1, a hoist 2, a hook 3, a fixed rod 4, a collision prevention block 5, and a pull rod 6. The hoist 2 is welded inside the cross beam 1. The fixed rod 4 penetrates through the left and right sides of the cross beam 1. The collision prevention block 5 is welded outside the cross beam 1. The pull rod 6 is embedded at the lower end of the hoist 2. The hook 3 is engaged with the lower end of the pull rod 6. The hoist 2 is provided with a rolling rod 21, a metal plate 22, a first motor 23, a slide rail 24, a second motor 25, and a steel cable 26. The first motor 23 is installed inside the metal plate 22. The rolling rod 21 is movably engaged in the middle of the first motor 23. The second motor 25 is welded to the lower end inside the metal plate 22. The uppermost end of the steel cable 26 is engaged with the outside of the second motor 25. The rolling rod 21 is movably matched with the slide rail 24. The slide rail 24 is welded inside the cross beam 1. The pull rod 6 is embedded at the lower end of the steel cable 26. The outside of the rolling rod 21 passes through the inside and outside of the metal plate 22 and contacts the slide rail 24. There are two slide rails 24, which are parallelly distributed at the left and right ends of the first motor 23, and there are two first motors 23, which are symmetrically distributed at the same straight line position. There are two fixed rods 4. There are two cross beams 1. The cross beam 1 and the fixed rod 4 form a square structure with each other. Thus, the hook 3 hooks the material. Under the rotation of the second motor 25, the steel cable 26 rotates and winds on the outside, driving the lower pull rod 6 and the hook 3 to lift and lower the material, so that the weight of the material is supported by the first motor 23 inside the metal plate 22. Furthermore, the first motor 23 is controlled to rotate the rolling rod 21, so that the rolling rod 21 rotates and moves in the slide rail 24, driving the second motor 25 to horizontally move between the two cross beams 1, and thus the material realizes the lifting and transfer effect.

[0021] The rolling rod 21 is provided with a blocking rod w1, a rotating rod w2, a bearing rod w3, and a slide bar w4. The bearing rod w3 is movably and bearingly matched in the middle of the rotating rod w2. The blocking rod w1 is embedded on the outer side of the lower end of the bearing rod w3. The blocking rod w1 is slidably matched with the slide bar w4. The outer side of the rotating rod w2 is extrusion-matched with the outer side of the slide bar w4. The slide bar w4 is welded to the inside of the slide rail 24. The side of the rotating rod w2 is movably engaged in the middle of the first motor 23. There are four blocking rods w1, which are symmetrically distributed on the left and right sides of the two first motors 23 respectively, and are symmetrically distributed in an inclined state of 45 degrees. The slide bar w4 is in an "L" shape. Thus, the first motor 23 drives the rotating rod w2 to rotate. Furthermore, the outer side of the rotating rod w2 horizontally extrudes and rolls at the highest position of the slide bar w4, avoiding a large frictional force between the outer side of the rotating rod w2 and the upper end of the slide bar w4. And when moving, when there is a gravity swing and pull, the blocking rod w1 at the lower outer side of the bearing rod w3 blocks and buffers the rotating rod w2, avoiding a large pulling force and causing unstable movement.

[0022] The blocking rod w1 is provided with a triangular block w11, a support rod w12, a ball w13, and an elastic plate w14. The ball w13 is fixedly embedded inside the lower end of the triangular block w11. The triangular block w11 is installed at the lower end of the support rod w12. The elastic plate w14 is attached inside the triangular block w11. The upper end of the support rod w12 is fixedly embedded outside the bearing rod w3. The elastic plate w14 divides the triangular block w11 into upper and lower parts. There are two balls w13, which are horizontally spaced. The elastic plate w14 is made of rubber and has the characteristic of being easily extruded and deformed. Thus, under the gravity of the material below the first motor 23, the rotating rod w2 is extruded against the upper end of the slide bar w4, and at the same time, driven by the rotating force of the first motor 23, the rotating rod w2 rolls while being extruded on the upper end of the slide bar w4, driving the lower end of the first motor 23 to move horizontally. At the same time, the bearing rod w3 is limited and translated in the middle bearing of the rotating rod w2. When a pulling force is generated due to shaking, the two blocking rods w1 at the lower end of the bearing rod w3 will generate a rotating force centered on the bearing rod w3. Then, through the elastic pressure of the elastic plate w14, the balls w13 at the lower end of the triangular block w11 roll while rubbing the surface of the slide bar w4, so that the bearing rod w3 connected to the support rod w12 generates a certain blocking force on the rotating rod w2, avoiding the unstable rolling and translation of the rotating rod w2 caused by the pulling force, and preventing the balls w13 from bearing the gravity of the material and rolling. It only needs to rub when there is a pulling force, preventing the easy generation of fine chips due to bearing the gravity and rolling.

[0023] The rotating rod w2 is provided with a machine rod w21, a friction plate w22, and an arc plate w23. The arc plate w23 is fixedly embedded outside the machine rod w21. The friction plate w22 is attached to the side of the arc plate w23. The machine rod w21 is movably and rotationally matched with the outside of the bearing rod w3 through a bearing. The outside of the arc plate w23 and the friction plate w22 are extrusion-fitted with the outside of the slide bar w4. The arc plate w23 is made of aluminum alloy and has the characteristics of large elasticity and strong toughness. The friction plate w22 is made of rubber and has the characteristic of being compressible and a relatively large surface friction force. Thus, after the machine rod w21 is rotated by the first motor 23, it is extruded and rolls on the surface of the slide bar w4. Furthermore, the arc plate w23 and the friction plate w22 are mutually extruded and fitted to roll on the surface of the slide bar w4, pressing on the upper end of the slide bar w4 while rolling under gravity, increasing the grasping force on the upper end of the slide bar w4 through the friction plate w22, preventing the occurrence of sliding friction and the generation of fine chips, and further enabling the machine rod w21 to stably roll and translate on the rotating rod w2.

[0024] A hydraulic device is provided outside the fixed rod 4. The hydraulic device is connected to the internal circuit of the hoist 2. And a signal controller is provided inside the hoist 2, which is wirelessly controlled and connected to the outside. Also, a circuit is connected inside the hoist 2, having an electrified effect. Thus, the hydraulic device can be telescopically controlled wirelessly, having the effect of driving the fixed rod 4 to extend and support, so that the fixed rod 4 is fixed on the wall above the clean room. Furthermore, the first motor 23 and the second motor 25 inside the hoist 2 are wirelessly controlled to move, realizing the transfer and lifting of materials.

[0025] Working principle: In the present utility model, by wirelessly controlling the telescopic movement of the hydraulic device, it has the effect of driving the fixed rod 4 to extend and support, so that the fixed rod 4 is fixed on the wall above the clean room. Furthermore, the first motor 23 and the second motor 25 inside the hoist 2 are wirelessly controlled to move. Then the hook 3 hooks the material, and under the rotation of the second motor 25, the steel cable 26 rotates and winds on the outside, driving the lower pull rod 6 and the hook 3 to lift and lower the material, so that the weight of the material is supported by the first motor 23 inside the metal plate 22. Furthermore, the first motor 23 is controlled to rotate the rolling rod 21. The first motor 23 drives the rotating rod w2 to rotate. Then the outside of the machine rod w21 horizontally presses and rolls at the highest point of the slide bar w4. Thus, the arc plate w23 and the friction plate w22 are mutually pressed and roll on the surface of the slide bar w4. While pressing the upper end of the slide bar w4 under gravity, it rolls, increasing the grasping force on the upper end of the slide bar w4 through the friction plate w22, realizing the effect of rolling and translation, and preventing sliding friction from generating fine chips.

[0026] In the present utility model, when the rotating rod w2 rolls and translates, when the gravity moves and sways and pulls, the blocking rod w1 at the lower end of the outer side of the bearing rod w3 blocks and buffers the rotating rod w2, avoiding the generation of a large pulling force that causes unstable movement. When a pulling force is generated during the swaying, the two blocking rods w1 at the lower end of the bearing rod w3 will generate a rotational force centered on the bearing rod w3. Then, through the elastic pressure of the elastic plate w14, the ball w13 at the lower end of the triangular block w11 rolls while rubbing the surface of the slide bar w4, so that the bearing rod w3 connected to the support rod w12 generates a certain blocking force on the rotating rod w2, blocking the swaying of the material to a certain extent, avoiding the unstable rolling and translation of the rotating rod w2 caused by the swaying pulling force, and preventing the ball w13 from bearing the gravity of the material and rolling. It only needs to rub when there is a pulling force, preventing the generation of fine chips due to bearing gravity and rolling.
