Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a segmented lifting and transferring device. Background Technology

[0002] In the field of industrial automation, precise material transfer is a crucial link in ensuring production efficiency and product quality. Currently, traditional material handling devices mostly employ a single-stage drive structure, where lifting and transferring actions rely on a single power source. This structure has significant limitations in practical applications: Firstly, the stroke of a single-stage design is limited by the specifications of the drive components, making it difficult to meet the needs of large-span, high-drop transfers. In multi-layer production lines or high-level material handling scenarios, additional auxiliary equipment is often required, increasing the equipment's footprint and cost. Secondly, when a single drive component simultaneously undertakes lifting and transferring actions, the concentrated load can easily lead to decreased operational stability, thus affecting transfer accuracy. Furthermore, traditional material handling devices lack structural rigidity, making them prone to vibration and swaying during high-speed transfers. This not only shortens the equipment's lifespan but can also cause material to fall off or shift position due to vibration, further hindering the improvement of production efficiency.

[0003] Therefore, it is necessary to design a segmented lifting and transferring device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a segmented lifting and transferring device that effectively increases the transfer stroke and operates stably.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a segmented lifting and transferring device, comprising a machine base, a mounting plate, a first slide assembly disposed on one side of the mounting plate, a second slide assembly disposed on the other side of the mounting plate, and a transferring assembly. The first slide assembly includes a first lead screw module and a first slide, the first lead screw module driving the first slide to move up and down. The second slide assembly includes a second lead screw module and a second slide, the second lead screw module driving the second slide to move up and down. The first slide is connected to the machine base, and the second slide is connected to the transferring assembly.

[0006] As a further improvement of the present invention, the first lead screw module includes a motor, a lead screw, two bearing seats connecting the lead screw to the mounting plate, and a coupling connecting the output shaft of the motor to the lead screw.

[0007] As a further improvement of the present invention, the second lead screw module includes a motor, a lead screw, two bearing seats connecting the lead screw to the mounting plate, and a coupling connecting the output shaft of the motor to the lead screw.

[0008] As a further improvement of the present invention, the bearing housing includes a support base, a bearing disposed on the support base, a stop ring and a fixing cover disposed on both sides of the bearing, and a locking nut disposed at one end of the lead screw.

[0009] As a further improvement of this utility model, the bearing located at the top is a deep groove ball bearing.

[0010] As a further improvement of the present invention, the mounting plate is provided with a buffer for limiting the upper and lower positions of the first slide and the second slide, and the buffer is provided on the bearing seat on the side facing the first slide or the second slide.

[0011] As a further improvement of this utility model, the length of the first slide in its moving direction is 2-4 times the length of the second slide in its moving direction, and the length of the first slide in its moving direction is 1 / 4-1 / 2 of its moving length.

[0012] As a further improvement of the present invention, the first slide assembly further includes two guide rails disposed on the mounting plate and two sets of sliders disposed on the first slide that cooperate with the guide rails to slide.

[0013] As a further improvement of the present invention, the second slide assembly further includes two guide rails disposed on the mounting plate and two sets of sliders disposed on the second slide that cooperate with the guide rails to slide.

[0014] As a further improvement of the present invention, the material transfer assembly is used to pick up and place materials, and includes a cantilever mounted on the second slide and a robotic arm mounted on the cantilever.

[0015] As can be seen from the above technical solutions, the segmented lifting and transferring device of this utility model significantly optimizes the performance of traditional transferring devices through innovative segmented drive design, and has the following advantages:

[0016] 1. The first and second slide components are driven independently. The segmented structure can achieve stroke superposition by adjusting the operating parameters of the two lead screw modules respectively. Compared with the single-segment device, its effective transfer stroke can be greatly improved, which can easily cover a variety of scenarios from low to high position and expand the applicability of the device.

[0017] 2. The first slide is connected to the machine base and bears the overall load and basic lifting function of the device. The second slide component directly drives the material transfer component to achieve precise material transfer. This segmented load-bearing design distributes the load to two independent drive systems, avoiding the load concentration problem of a single-segment structure. The stability and positioning accuracy during operation are improved.

[0018] 3. The two lead screw modules can be controlled independently, supporting synchronous or asynchronous operation, and can flexibly adjust the motion trajectory according to material characteristics (such as weight and size) and production rhythm. When transferring light materials, a rapid response can be achieved by increasing the running speed of the second slide assembly; when handling heavy loads, safety can be ensured by the slow and stable operation of the first slide assembly, enhancing equipment compatibility.

[0019] 4. The connection between the machine base and the first slide enhances the overall structural stability. The independent support of the two slide components reduces stress concentration caused by the cantilever structure and reduces the amount of structural deformation of the device. At the same time, the distributed load reduces the wear rate of the screw module and significantly reduces maintenance costs. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figure 1 As shown, this utility model provides a segmented lifting and transferring device, which includes a machine base 10, a mounting plate 20, a first slide assembly 30 disposed on one side of the mounting plate 20, a second slide assembly 40 disposed on the other side of the mounting plate 20, and a transferring assembly 50.

[0025] Please participate together Figure 2 As shown, the first slide assembly 30 includes a first lead screw module and a first slide 35, the first lead screw module driving the first slide 35 to move up and down. The second slide assembly 40 includes a second lead screw module and a second slide 45, the second lead screw module driving the second slide 45 to move up and down. The first slide 35 is connected to the machine base 10, and the second slide 45 is connected to the material transfer assembly 50.

[0026] The first lead screw module includes a motor 31, a lead screw 34, two bearing seats 33 and 37 connecting the lead screw 34 to the mounting plate 20, a coupling 32 connecting the output shaft of the motor 31 to the lead screw 34, a lead screw nut 38 threadedly connected to the lead screw 34, two guide rails 39 on the mounting plate 20, and two sets of sliders 36 on the first slide 35 that slide in cooperation with the guide rails 39. Each set of sliders 36 can be configured with two sliders, positioned near both ends of the first slide 35. The lead screw nut 38 is fixed to the first slide 35.

[0027] Please refer to Figure 3 As shown, the bearing housing 33 includes a support base 331, a bearing 332 mounted on the support base 331, retaining rings 334 and a fixing cover 333 on both sides of the bearing 332, and a locking nut 335 at one end of the lead screw 34. The support base 331 provides the mounting foundation and structural support for the entire bearing housing, and its internal cavity is used to accommodate components such as the bearing 332. The bearing 332 is installed inside the support base 331 and is the core component for realizing the rotation of the lead screw 34. It can reduce the frictional resistance when the lead screw 34 rotates, enabling the lead screw 34 to rotate smoothly and efficiently, while bearing the load generated during the operation of the lead screw 34. The retaining rings 334 and the fixing cover 333 cooperate to axially position the bearing 332, preventing the bearing 332 from moving axially within the support base 331 and ensuring the stability of the bearing 332 during operation. A locking nut 335 is installed at one end of the lead screw 34 to axially lock the lead screw 34 and prevent it from moving axially during operation. The bearing 332 is preferably a deep groove ball bearing. The structure of the bearing housing 37 and its fit with the lead screw 34 are the same as those of the bearing housing 33, and will not be described further here.

[0028] The second lead screw module has the same structure as the first lead screw module, the only difference being the length of the first slide 35 and the second slide 45. Specifically, the length of the first slide 35 in its moving direction (i.e., the vertical direction) is 2-4 times the length of the second slide in its moving direction (i.e., the vertical direction). The first slide 35, as the basic load-bearing component, needs to support the weight of the entire device (including the first slide assembly structure, mounting plate 20, second slide assembly 40, material transfer assembly 50, and the material). By setting the length of the first slide 35 to 2-4 times that of the second slide, the contact area with the machine platform and the support span can be effectively increased, reducing the stress per unit area. The longer support length can distribute the stress generated by the load to a larger area, reducing structural deformation.

[0029] In addition, the vertical length of the first slide 35 is 1 / 4 to 1 / 2 of its moving length (i.e., stroke). This setting can maintain structural rigidity while ensuring sufficient stroke. If the length is too short, the cantilever length of the lead screw module will be too long, resulting in large deflection at the end of the stroke and affecting positioning accuracy; if the length is too long, although it can improve rigidity, it will increase the overall height of the device, compress the effective working space, and increase material costs and drive energy consumption.

[0030] The mounting plate 20 is provided with buffers 330 and 370 for limiting the upper and lower movement of the first slide 35. The buffers 330 and 370 are located on the bearing seats 33 and 37 facing the first slide 35. Similarly, the second slide 45 is also limited by buffers, which will not be described in detail here.

[0031] The material handling assembly 50 is used for picking up and placing materials, and includes a cantilever mounted on the second slide 45 and a robotic arm mounted on the cantilever. The robotic arm, as the component that directly performs the picking and placing actions, can be flexibly selected from various existing forms based on the characteristics of the actual material and specific production needs. For example, for materials with a certain hardness and regular shape, a gripper-type robotic arm can be used, achieving stable gripping through the opening and closing of the grippers; if the material surface is relatively flat and the texture is relatively soft, a suction cup-type robotic arm can be selected, relying on the suction force generated by air pressure to safely pick up and place the material; and when the material needs to be picked up and placed in a deeper or specific space, a telescopic arm-type robotic arm can easily complete the corresponding actions due to its telescopic characteristics. The structural design of these robotic arms can all refer to existing mature technologies in the industry. Due to the diversity of actual application scenarios, no excessive restrictions are placed on their specific structures here, in order to meet the usage requirements under different working conditions.
