Description

Technical Field

Class 1000 clean rooms have emerged and become key production sites. In these advanced production processes, it is often necessary to transport various high-precision and expensive products or parts to specific locations and accurately place them on corresponding equipment or fixtures for subsequent processing, testing or assembly.

[0003] Traditional lifting equipment has exposed many limitations in the Class 1000 clean room environment. On the one hand, its lifting height is limited, which makes it difficult to meet the growing diversified needs of production processes for product placement heights, and it is impossible to deliver products to the designated locations of equipment or high-rise shelves, thus restricting the optimization of production layout and the improvement of production efficiency. On the other hand, traditional equipment lacks precision in positioning and placement and is cumbersome to operate. It is impossible to quickly and accurately adjust products to the required precise position, which not only reduces production efficiency, but may also damage high-precision products due to improper placement, resulting in high economic losses.

[0004] At the same time, in a Class 1000 clean room, the stability of the equipment during operation and the dust prevention of the equipment are crucial. Due to the simple design of the supporting structure of traditional lifting equipment and the lack of effective stability enhancement measures, it is easy to shake or move during operation, which not only affects the service life of the equipment itself, but also may cause secondary lifting of dust particles, destroying the clean environment of the clean room, and further affecting product quality and the reliability of the production process.

[0035] Among them, a plurality of reinforcing ribs 17 are fixedly connected to the front side of the secondary lifting frame 16, and a magnetic strip 26 is embedded in the front side of the plurality of reinforcing ribs 17. Two flexible steel strips 38 are arranged on the front side of the secondary lifting frame 16, and the two ends of the two flexible steel strips 38 are respectively fixedly connected to the upper and lower ends of the secondary lifting frame 16.

[0037] Among them, the rotary joint 20 and the secondary joint frame 29 are both provided with a reducer 35 and a magnetic powder brake 36. The setting of the magnetic powder brake 36 can control the rotational torque of the ball shaft ring 21 according to the intensity of the excitation current. The input shaft of the reducer 35 is fixedly connected to the output shaft of the magnetic powder brake 36. The upper ends of the primary joint frame 25 and the tertiary joint fixing frame 30 are both equipped with electromagnetic brakes 23. The driven part of the electromagnetic brake 23 is fixedly connected to the rotary joint 20 or the secondary joint frame 29. The setting of the electromagnetic brake 23 ensures that when the teeth on the electromagnetic brake 23 are engaged, the corresponding primary joint frame 25, the secondary joint frame 29 or the tertiary joint fixing frame 30 will not rotate. When engaged, the corresponding first-level joint frame 25, second-level joint frame 29 or third-level joint fixing frame 30 can rotate, the front side of the rectangular plate 18 is fixedly connected with the first fixing steel 24, the active parts of the two electromagnetic brakes 23 located on the front side are jointly fixedly connected to the second fixing steel 27, and the active part of the electromagnetic brake 23 located on the rear side is fixedly connected to the first fixing steel 24, and ball shaft rings 21 are provided between the rotating joint 20 and the second-level joint frame 29, and between the second-level joint frame 29 and the third-level joint fixing frame 30.

The outer sides of the plurality of rotating sleeves 9 are fixedly connected with limiting blocks, and each limiting block is slidably connected with a fixing pin 11 matched with the fixing hole 10, and a pull ring is provided at the upper end of each fixing pin 11. The upper end of the base plate 1 is installed with a plurality of encoders matched with the rotating sleeve 9, and the setting of the encoder can feed back the rotation angle of the rotating sleeve 9 to the controller in real time, so as to facilitate the staff to grasp the rotation angle of the rotating sleeve 9.

[0039] The functional principle of the present invention can be explained through the following operation mode: first, the product is placed on the lifting plate 32, and the staff controls the operation of the first motor 7, and its output shaft drives the first commutator 15 to operate, thereby causing the two electric cylinders 40 to rotate synchronously. Since the fixed blocks on the two electric cylinders 40 are respectively fixedly connected to the top inner wall of the secondary lifting frame 16, and the secondary lifting frame 16 is slidably connected to the multiple first guide rails 41, this structural design converts the rotational motion of the electric cylinder 40 into the vertical lifting motion of the secondary lifting frame 16, thereby realizing the function of the lifting device in the primary lifting aspect.

[0040] When the product needs to be lifted to a higher height, the first-level lifting assembly is used to lift the second-level lifting frame 16 to the highest height, and then the second motor 14 is controlled to operate, and its output shaft drives the second commutator 39 to operate, so that the screw rod rotates. The lifting plate 43 threadedly connected to the screw rod rises vertically under the guidance of the two second guide rails 44. At the same time, the two sliding plates 19 on the front side of the lifting plate 43 will move in front of the second-level lifting frame 16 with the movement of the lifting plate 43, and drive the rectangular plate 18 and its front articulated arm and the product to move upward;

[0041] After the product is moved to a suitable height, the staff can climb to a certain height on the ladder. Due to the setting of the rotating joint 20 and the secondary joint frame 29, the staff can push or pull the handle to drive the product to rotate through the lifting plate 32, and then quickly adjust the product to a suitable angle position for placement. When the rotation angle of the joint arm is accurately adjusted to place the product, the teeth on the electromagnetic brake 23 are not engaged, and the magnetic powder brake 36 does not brake. At this time, the ball ring 21 accurately controls the rotation speed and angle of the rotating joint 20 and the secondary joint frame 29 and other components through the reducer 35, so as to achieve precise movement of the joint arm, thereby quickly and accurately adjusting the product to the position where it needs to be placed.

[0042] When using the equipment, after moving the equipment to the specified position by means of the multiple casters 5, the multiple foot cups 6 are rotated so that the multiple foot cups 6 are pressed against the ground, and then the multiple rotating feet 12 are rotated according to the quality of the lifted product, thereby rotating the multiple rotating feet 12 to a suitable angle in turn. When rotating the rotating feet 12, the staff needs to lift the fixing pin 11 first so that the fixing pin 11 is away from the fixing hole 10, and then the rotating foot 12 can be rotated. When the rotating foot 12 is rotated to a suitable angle, the fixing pin 11 is released, and under the action of the gravity of the fixing pin 11, the fixing pin 11 enters the fixing hole 10, and then the staff rotates the second supporting foot 13, so that the multiple second supporting feet 13 are pressed against the ground.

[0043] Example 2

[0044] Reference Figure 8 The difference between this embodiment and embodiment 1 is that a triangular steel 28 is fixedly connected to the front side of the fixing plate 31, a first hook 42 is installed at the lower end of the triangular steel 28, and the fixing plate 31 and the first hook 42 constitute a hook assembly.

[0045] In this embodiment, when the product to be lifted needs to be lifted using the first hook 42, the staff can loosen multiple nuts to remove the fixing plate 31 and the lifting plate 32, and then pass the two positioning pins 33 through the positioning holes on the fixing plate 31 corresponding to the first hook 42, and then use multiple bolts to fix the fixing plate 31 and the three-level joint fixing frame 30 together for use.

[0046] Example 3

[0047] Reference Fig. 9 The difference between this embodiment and embodiment 1 is that a dust cover 34 is fixedly connected to the front side of the fixing plate 31, an electric winch is installed in the dust cover 34, a flexible sling is wrapped around the electric winch, one end of the flexible sling extends to the outside and is fixedly connected to the second hook 22, and the fixing plate 31, the electric winch, the flexible sling and the second hook 22 constitute an electric winch assembly.

[0048] In this embodiment, when the product to be lifted needs to be lifted using an electric winch and a second hook 22, the staff can loosen a plurality of nuts to remove the fixing plate 31 and the lifting plate 32, and then pass the two positioning pins 33 through the positioning holes on the fixing plate 31 corresponding to the dust cover 34, and then use a plurality of bolts to fix the fixing plate 31 and the three-stage joint fixing frame 30 together for use.
