Technical Field

[0001] This utility model relates to the field of semi-automatic production line technology, specifically a lifting device for semi-automatic production lines. Background Technology

[0002] In modern industrial production, semi-automated production lines are an important means to improve production efficiency and reduce labor intensity. As a type of elevator, lifting pallets are widely used in semi-automated production lines to transport goods on the production line from a lower position to a higher position.

[0003] A search revealed, for example, a lifting pallet for an assembly line disclosed in Chinese Utility Model Patent Publication No. CN221191423U. This design directly mounts a motor and other lifting components below the pallet frame. While this design achieves the lifting function of the pallet frame, it generates vibrations during actual operation when carrying materials. These vibrations are directly transmitted to the motor and lifting components below, increasing mechanical stress and accelerating wear and aging. Over time, the performance of the motor and lifting components gradually declines, affecting not only the operational accuracy and stability of the lifting device but also potentially leading to equipment failure, increased maintenance costs, and downtime. Therefore, a semi-automatic lifting device for assembly lines is proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a semi-automatic lifting device for production lines that can prevent the vibration of the pallet frame from affecting the service life of the lifting components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for a semi-automatic production line, comprising a base, two fixed columns fixedly installed on the top of the base, a production line tray frame arranged between the two fixed columns, a functional box fixedly installed on the top of the base, and a lifting component arranged inside the functional box;

[0006] The lifting assembly includes a drive motor, which is fixedly mounted on the front surface of the functional box. A worm gear is fixedly mounted on the output end of the drive motor. A worm wheel meshes with the top of the worm gear. A first rotating rod is fixedly mounted in the middle of the worm wheel. Both ends of the first rotating rod are fixedly mounted with driving bevel gears. The bottoms of the two driving bevel gears are meshed with driven bevel gears. A second rotating rod is fixedly mounted in the middle of the two driven bevel gears. A threaded rod is fixedly mounted on the top of the two second rotating rods. A lifting screw is threaded onto the surface of the two threaded rods.

[0007] Furthermore, a first fixing ring is fixedly installed on both the left and right sides of the assembly line tray frame, and the two first fixing rings are slidably installed with the fixing column respectively.

[0008] Furthermore, the worm gear is rotatably mounted on the inner rear wall of the functional box, and two stabilizing plates are fixedly installed inside the functional box. Both stabilizing plates have rotating holes inside, and the two stabilizing plates are movably mounted to the first rotating rod through the rotating holes.

[0009] Furthermore, both second rotating rods are rotatably mounted on the inner bottom wall of the functional box, and a conveyor tray frame is fixedly mounted on the top of the two lifting screw cylinders.

[0010] Furthermore, a second fixing ring is fixedly installed on each of the two opposing sides of the lifting screw cylinders, and the two second fixing rings are slidably installed with the fixing column. The top of the functional box is provided with an opening adapted to the lifting screw cylinder.

[0011] Furthermore, a support base assembly is provided on the top of the functional box. The support base assembly includes a support body, which is fixedly installed on the top surface of the functional box. A bearing plate is slidably installed inside the support body. Three spring dampers are fixedly installed between the bearing plate and the inner bottom wall of the functional box. A support column is fixedly installed on the top of the bearing plate, and a production line tray frame is fixedly installed on the top of the support column.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This semi-automatic production line uses a lifting device that separates the pallet frame from the lifting assembly by setting up an independent lifting component. The lifting of the pallet frame is supported by a support base. Specifically, the lifting assembly includes key components such as a drive motor, worm gear, and worm wheel. The drive motor, through the cooperation of the worm gear and worm wheel, drives the pallet frame to move smoothly up and down in the vertical direction.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 The lifting device for a semi-automatic production line in this embodiment includes a base 1, two fixed columns 2 are fixedly installed on the top of the base 1, a production line tray frame 3 is arranged between the two fixed columns 2, a function box 4 is fixedly installed on the top of the base 1, and a lifting component 5 is arranged inside the function box 4.

[0021] The lifting assembly 5 includes a drive motor 501, which is fixedly mounted on the front surface of the functional box 4. A worm gear 502 is fixedly mounted on the output end of the drive motor 501. A worm wheel 503 is meshed on the top of the worm gear 502. A first rotating rod 504 is fixedly mounted in the middle of the worm wheel 503. Both ends of the first rotating rod 504 are fixedly mounted with driving bevel gears 505. The bottoms of the two driving bevel gears 505 are meshed with driven bevel gears 506. A second rotating rod 507 is fixedly mounted in the middle of the two driven bevel gears 506.

[0022] like Figure 1 As shown, by installing the first fixing ring, the movement of the assembly line tray frame 3 can be guided, allowing it to move smoothly.

[0023] like Figure 3 As shown, by setting a stabilizing plate and a rotating hole, support can be provided for the rotation of the first rotating rod 504 so that it can rotate stably and remain smooth during rotation.

[0024] like Figure 1 and Figure 2As shown, by setting a second fixing ring, the lifting screw cylinder 509 can move vertically along with the rotation of the threaded rod 508 when the threaded rod 508 rotates, instead of rotating along with the rotation of the threaded rod 508.

[0025] like Figure 1 and Figure 4 As shown, by setting up a support base assembly 6, which includes a support base body 601, a bearing plate 602, a spring damper 603, and a support column 604, when the lifting assembly line pallet frame 3 is lifted, the bearing plate 602 moves up and down inside the support base body 601. The spring damper 603 provides elastic support to ensure that the bearing plate 602 can smoothly bear the load during the movement, improve the lifting stability, and at the same time reduce the pressure on the lifting screw cylinder 509.

[0026] When implementing this procedure, please follow these steps:

[0027] 1) First, start the drive motor 501. The drive motor 501 drives the first rotating rod 504 to rotate through the cooperation of the worm 502 and the worm wheel 503.

[0028] 2) Then the first rotating rod 504 drives the threaded rod 508 to rotate through the cooperation of the driving bevel gear 505 and the driven bevel gear 506, etc.

[0029] 3) The threaded rod 508 drives the lifting screw cylinder 509 to move in the vertical direction;

[0030] 4) Finally, the lifting screw 509 drives the production line tray frame 3 to move in the vertical direction.

[0031] In summary, this semi-automatic production line lifting device separates the pallet frame from the lifting assembly 5 by setting up an independent lifting component 5, and supports the lifting of the pallet frame through a support base. Specifically, the lifting assembly 5 includes key components such as a drive motor 501, a worm gear 502, and a worm wheel 503. The drive motor 501, through the cooperation of the worm gear 502 and the worm wheel 503, drives the pallet frame to move smoothly up and down in the vertical direction. This design not only effectively avoids the impact of pallet frame vibration on the lifting assembly 5 and extends the service life of the component, but also ensures the stability of the pallet frame during the lifting process through the setting of the support base assembly 6, thereby improving the overall performance of the lifting device.
