Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a workpiece lifting and transfer mechanism. Background Technology

[0002] In the mechanical manufacturing process, lifting and transferring workpieces are common operations. In automated production lines or logistics warehouses in large factories, workpieces need to be frequently moved from one location to another, which may involve transfers at different heights. In such cases, efficient and precise workpiece lifting and transferring mechanisms are required to ensure the smooth operation of the production process.

[0003] Known lifting and transfer mechanisms include belt-driven transplanters, chain-driven transplanters, and roller-driven transplanters. These mechanisms use cylinders or other linear motion elements (such as hydraulic cylinders or electric push rods) to push the lifting plate upwards or pull it downwards. A translation conveyor (belt, chain, roller, etc.) is installed on the lifting plate. Once the item is lifted to a certain height, the translation conveyor begins to operate. After the item is delivered to its designated position, the lifting mechanism lowers the translation conveyor. This mechanism is suitable for conventional production line applications.

[0004] Existing lifting and transfer mechanisms often employ relatively simple structural designs. Some mechanisms only use a single track and drive device to transport workpieces in one direction. This structure lacks flexibility when facing complex production layouts or special working environments and cannot meet the needs of multi-directional transportation. Although there are some lifting and transfer mechanisms that can achieve multi-directional movement, they often do so through complex mechanical structures or by adding a large number of control components. This not only significantly increases the cost of the equipment but also presents greater challenges in equipment maintenance and debugging. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a workpiece lifting and transfer mechanism, which aims to improve the problem that the existing lifting and transfer structure has poor flexibility and cannot meet the needs of multi-directional transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a workpiece lifting and transfer mechanism, comprising a slide rail base, a carrier plate slidably connected to the upper surface of the slide rail base, a protective component provided on the upper surface of the carrier plate, a guide rail II fixedly connected to the upper surface of the carrier plate, a slider II slidably connected to the outer wall of the guide rail II, a cylinder fixedly connected to the upper surface of the carrier plate, a base plate fixedly connected to the output end of the cylinder, a workpiece locator fixedly connected to the upper surface of the base plate, a motor II fixedly connected to the upper surface of the base plate, a transmission belt fixedly connected to the output end of the motor II, a gear slidably connected to the inner wall of the transmission belt, a roller fixedly connected to the outer wall of the gear, and the outer wall of the roller rotatably connected to the inner wall of the slider II.

[0007] Furthermore, the protective component includes a protective plate, the lower surface of which is fixedly connected to the upper surface of the carrier plate, and the outer wall of the base plate is slidably connected to the inner wall of the protective plate.

[0008] Furthermore, a guide rail is fixedly connected to the upper surface of the slide rail base, the carrier plate is slidably connected to the outer wall of the guide rail, a motor is fixedly connected to the upper surface of the slide rail base, a drive wheel is fixedly connected to the output end of the motor, a belt is slidably connected to the outer wall of the drive wheel, a coupling is fixedly connected to the outer wall of the drive wheel, a fixing block is fixedly connected to the upper surface of the slide rail base, and the outer wall of the drive wheel is rotatably connected above the fixing block.

[0009] Furthermore, a slider is slidably connected to the outer wall of the belt, and the slider is slidably connected inside the carrier plate.

[0010] Furthermore, a limiting block is fixedly connected to the upper surface of the slide rail base, and the inner wall of the limiting block is slidably connected to the outer wall of the carrier plate.

[0011] Furthermore, a positioning rod is fixedly connected to the inner wall of the protective plate, and a wire is fixedly connected above the positioning rod.

[0012] Furthermore, a positioning detector is fixedly connected to the side of the slide rail base away from the motor.

[0013] Furthermore, a bracket is fixedly connected to the outer wall of the slide rail base.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the lateral and vertical transportation is realized through the coordinated work of components such as the slide rail base, carrier plate, guide rail, cylinder, and motor. The carrier plate can slide on the upper surface of the slide rail base, and the lateral movement is realized through the cooperation of motor one, drive wheel, belt, and slider one. The cylinder can drive the base plate and workpiece positioner to move up and down, thereby meeting the needs of transferring workpieces in different directions. It effectively solves the problem that the existing lifting and transfer mechanism can only transport workpieces in one direction and cannot be applied to complex production layouts or special working environments.

[0016] 2. In this utility model, a ground rail type translation mechanism is used to replace the traditional conveyor line + lifting and translation mechanism. It occupies a small area and is especially suitable for situations where the site space is small and the original line size is fixed. It eliminates redundant lines, which not only simplifies the overall structure and reduces the number of equipment parts, but also reduces the equipment manufacturing and installation costs. In addition, it is more convenient in terms of later maintenance, reducing maintenance costs, thereby saving expenses for enterprises and improving economic efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Reference Figure 1 and Figure 2This utility model provides an embodiment of a workpiece lifting and transfer mechanism, including a slide rail base 1. The slide rail base 1 serves as the foundation for overall support and installation of other components, providing a stable platform for the entire transfer mechanism. A carrier plate 16 is slidably connected to the upper surface of the slide rail base 1. The carrier plate 16 can move smoothly laterally on the slide rail base 1, thereby realizing the horizontal transfer of the workpiece. A protective component is provided on the upper surface of the carrier plate 16, including a protective plate 11. The lower surface of the protective plate 11 is fixedly connected to the upper surface of the carrier plate 16, and its function is to protect the internal components and prevent external factors from interfering with or damaging the internal operating components. At the same time, the outer wall of the base plate 15 slides... Connected to the inner wall of the protective plate 11, this connection structure makes the base plate 15 more stable during lifting and lowering. The protective plate 11 can also, to a certain extent, prevent the base plate 15 and its components from lateral collisions or impacts, ensuring the safety of equipment operation. A guide rail 17 is also fixedly connected to the upper surface of the carrier plate 16, and a slider 21 is slidably connected to the outer wall of the guide rail 17, providing guidance and support for the movement of subsequent components. The cylinder 20, fixedly connected to the upper surface of the carrier plate 16, is a key component for realizing the lifting function; its model is DSBC-125-200-PPVA-N3. The output end of the cylinder 20 is fixedly connected to the base plate 15, and the lower surface of the slider 21 is fixedly connected to the upper surface of the base plate 15. The telescopic movement of cylinder 20 can precisely control the vertical height adjustment of the base plate 15 and its components, thereby meeting the workpiece transfer needs at different height levels. A workpiece locator 13 is fixedly connected to the upper surface of the base plate 15. The function of the workpiece locator 13 is to accurately position the workpiece during the transfer process, ensuring that the workpiece maintains an accurate position during lifting and moving, preventing workpiece deviation or shaking, and ensuring the accuracy and stability of the transfer. The second motor 12, which is a variable frequency geared motor, is fixedly connected to the upper surface of the base plate 15. The specific model of the second motor 12 is SF67DT80K4. Its output end is fixedly connected to a transmission belt 22. The second motor 12 can be adjusted according to actual needs. The running speed of the transmission belt 22 enables smooth connection with the loading and unloading line. A gear 24 is slidably connected to the inner wall of the transmission belt 22, and a roller 14 is fixedly connected to the outer wall of the gear 24. The outer wall of the roller 14 is rotatably connected to the inner wall of the slider 21. When the motor 212 drives the transmission belt 22 to rotate, it drives several rollers 14 to rotate, thereby realizing the conveying and loading operation of the workpiece. This ensures that the workpiece can be smoothly transferred on the carrier plate 16, improving the efficiency and reliability of loading. A positioning rod 18 is fixedly connected to the inner wall of the protective plate 11, and a line body 10 is fixedly connected above the positioning rod 18. The line body 10 works in conjunction with the roller 14 to complete the loading work, further optimizing the loading process and stability.

[0026] Reference Figure 1 - Figure 5The slide rail base 1 serves as the basic support component of the entire workpiece lifting and transfer mechanism. A guide rail 5 is fixedly connected to its upper surface. The guide rail 5 provides precise guidance for the lateral sliding of the carrier plate 16, ensuring that the carrier plate 16 maintains linear motion during movement and improving the accuracy of the transfer. The carrier plate 16 is internally slidably connected to the outer wall of the guide rail 5, allowing the carrier plate 16 to smoothly move laterally along the guide rail 5, realizing the horizontal transport of the workpiece. A motor 2, fixedly connected to the upper surface of the slide rail base 1, is the power source driving the lateral movement of the carrier plate 16. Its specific model is SF67DT80K4. A drive wheel 3 is fixedly connected to the output end of the motor 2. Driven by motor 2, the drive pulley 3 rotates. The belt 4, slidably connected to the outer wall of the drive pulley 3, transmits power through the friction between the belt 4 and the drive pulley 3. The coupling 23, fixedly connected to the outer wall of the drive pulley 3, connects motor 2 and the drive pulley 3, ensuring stable power transmission and compensating for installation errors between them to some extent, reducing vibration and noise during operation. The fixing block 9, fixedly connected to the upper surface of the slide rail base 1, provides stable support and rotational constraint for the drive pulley 3, allowing it to rotate smoothly above the fixing block 9, ensuring more stable and reliable transmission of the belt 4. The belt 4 is slidably connected to the outer wall of the drive pulley 3... Slider 6 is slidably connected inside the carrier plate 16. When the belt 4 moves under the drive of the drive wheel 3, slider 6 slides inside the carrier plate 16 along with the belt 4, thereby driving the carrier plate 16 to move laterally on the guide rail 5. This effectively transmits the power of the motor 2 to the carrier plate 16, enabling the carrier plate 16 to move in a predetermined direction and speed, meeting the workpiece transfer requirements at different positions. A limiting block 7 is fixedly connected to the upper surface of the slide rail base 1, and its inner wall is slidably connected to the outer wall of the carrier plate 16. The main function of the limiting block 7 is to limit the movement range of the carrier plate 16, preventing it from exceeding the safe range during lateral movement and avoiding collisions. In the event of a collision with other equipment, the safety and stability of the equipment operation are ensured. The position detector 19, which is fixedly connected to the side of the slide rail base 1 away from the motor 2, is used to detect the moving position of the carrier plate 16. When the carrier plate 16 reaches a specific position during lateral movement, the position detector 19 can detect it in time and send a signal. This signal can be used to control the stop or start of the motor 2, realize the precise positioning of the carrier plate 16, and ensure that the workpiece can be accurately transported to the designated location, thereby improving the accuracy and reliability of the transfer. The bracket 8, which is fixedly connected to the outer wall of the slide rail base 1, plays a role in strengthening the structural strength of the slide rail base 1, making the entire mechanism more stable during operation.

[0027] Working Principle: The front section of the conveyor 10 delivers the pallet containing the workpiece to the roller conveyor line. At this time, motor 212 starts, driving the transmission belt 22 to rotate. Both motors 21 and 12 are SEW motors, specifically model SF67DT80K4. The transmission belt 22 drives the gear 24, which is slidably connected to the inner wall, to rotate. Since the outer wall of the gear 24 is fixedly connected to the roller 14, and the outer wall of the roller 14 is rotatably connected to the inner wall of the slider 21, the roller 14 rotates along with the gear 24, thereby realizing the conveying and loading operation of the workpiece. At the same time, the line 10 and the roller 14 work together to further optimize the loading process and ensure that the workpiece can be smoothly transferred on the carrier plate 16. After completion, the workpiece positioner 13 begins to operate, precisely positioning the workpiece to ensure it maintains an accurate position throughout subsequent lifting and movement, preventing workpiece shifting or shaking, and guaranteeing the accuracy and stability of the transfer. Once the workpiece is positioned, the cylinder 20 (model DSBC-125-200-PPVA-N3) begins to operate, precisely controlling the vertical adjustment of the base plate 15 and its upper mounting components through its telescopic movement, thereby meeting the workpiece transfer needs at different heights. During this process, the outer wall of the base plate 15 slides against the inner wall of the protective plate 11. The protective plate 11 not only protects the internal components but also prevents external damage. The cylinder 20 also helps to stabilize the base plate 15 during lifting, preventing lateral collisions or impacts. After the cylinder 20 lifts the workpiece to a suitable height, the motor 2 starts, driving the drive wheel 3 to rotate. The drive wheel 3 transmits power to the slider 6 via the belt 4. The slider 6 is slidably connected inside the carrier plate 16. When the slider 6 moves under the drive of the belt 4, it causes the carrier plate 16 to move laterally on the guide rail 5. The guide rail 5 provides precise guidance for the lateral sliding of the carrier plate 16, ensuring that the carrier plate 16 maintains linear motion during movement. This allows the carrier plate 16 to move horizontally in a predetermined direction and speed, transporting the workpiece to the designated location. During this process, the limit block 7 restricts the movement range of the carrier plate 16 to prevent it from exceeding the safe range. The position detector 19 detects the movement position of the carrier plate 16 in real time. When the carrier plate 16 reaches a specific position, the position detector 19 sends a signal to control the stop or start of the motor 2, so as to achieve precise positioning of the carrier plate 16. After the carrier plate 16 transports the workpiece to the designated location, it waits for unloading. After unloading is completed, the motor 2 reverses and the carrier plate 16 returns to the original position with the lifting mechanism. After the carrier plate 16 returns to the original position, the cylinder 20 descends to restore the roller conveyor line to the initial height. Then the roller conveyor line sends the empty pallet back to the front section of the line 10 to complete one work cycle and wait for the next loading operation.
