Description

Technical Field

[0001] This utility model relates to the technical field of cargo handling, specifically to a lifting and positioning structure for a transfer and handling device. Background Technology

[0002] In modern manufacturing, with increasingly fierce market competition and ever-increasing demands for product quality and production efficiency, automated production has gradually become the mainstream trend. Automated production lines need to achieve efficient and precise material transfer between different workstations. Transfer and handling devices, as a crucial component, are responsible for moving workpieces from one location to another. The lifting and positioning structure, as an important part of the transfer and handling device, directly affects the production efficiency and product quality of the entire production line. Some existing technologies rely on manual adjustment and confirmation for positioning. Workers place parts on a support platform, measure the distance between the part's edge and the assembly datum using calipers, manually rotate the screw to adjust the height of the support platform, and then use positioning pins inserted into the positioning holes of the part for fixation. However, the aforementioned common lifting and positioning mechanisms still have shortcomings:

[0003] Manual assisted lifting and positioning is prone to insufficient accuracy, and the large amount of manual intervention will increase labor costs and reduce efficiency, making it difficult to meet the needs of large-scale production. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting and positioning structure for a transfer and handling device, so as to solve the problems mentioned in the background art, which are that manual assisted lifting and positioning is prone to insufficient accuracy, and that a large amount of manual intervention will increase labor costs and reduce efficiency, making it difficult to meet the needs of large-scale production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting and positioning structure for a transfer and handling device, comprising a supporting base plate, a mounting bracket fixedly connected to the bottom of the supporting base plate, a cylinder assembly disposed in the middle of the mounting bracket, lifting sleeves disposed at the four corners of the surface of the mounting bracket, and sliding rod assemblies slidably connected to adjacent two lifting sleeves, a connecting assembly fixedly connected to one end of the cylinder assembly, a support plate assembly fixedly connected to the top of the connecting assembly, side supports disposed on both sides of the surface of the supporting base plate, multiple L-shaped fixing brackets disposed at the connection points between the two side supports and the supporting base plate, and a positioning mechanism disposed between the two support assemblies.

[0006] Preferably, the cylinder assembly includes a drive cylinder, and mounting brackets are fixedly connected to both sides of the drive cylinder, and both mounting brackets are fixedly connected to the mounting support, which facilitates the automatic driving of the lifting support plate to move.

[0007] Preferably, the slide rod assembly includes two supporting slide rods, a limiting block, and an intermediate connecting plate. One end of each of the two supporting slide rods is fixedly connected to one side of the limiting block, and the other end of each of the two supporting slide rods is fixedly connected to one side of the intermediate connecting plate, which is beneficial to the stable operation of the lifting mechanism.

[0008] Preferably, buffers are provided on both sides of the bottom end of the mounting bracket, and one side of the limiting block is in contact with one side of the buffer.

[0009] Preferably, the connecting assembly includes a rotary cylinder, which is disposed on the intermediate connecting plate. The output end of the rotary cylinder is fixedly connected to a connecting support plate. Positioning heads are fixedly connected to both ends of the top of the connecting support plate, and connecting blocks are fixedly connected to both sides of the connection between the two positioning heads and the connecting support plate.

[0010] Preferably, the support plate assembly includes a lifting support plate, and positioning grooves are provided at both ends of the bottom of the lifting support plate. Fixing blocks are provided on both sides of the connection between the two positioning grooves and the lifting support plate.

[0011] Preferably, the positioning mechanism includes multiple positioning brackets, which are respectively mounted on two side brackets. A transmitter and a receiver are respectively fixedly installed on one side of the two symmetrical positioning brackets, which helps to improve the accuracy of the lifting mechanism.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the lifting mechanism is driven by a driving cylinder and supported by four support slide rods to ensure stability during the lifting process. A buffer and positioning mechanism are also provided. The positioning mechanism is implemented using a through-beam photoelectric sensor. A transmitter and receiver are respectively installed on two side supports. After the lifting support plate rises to the set position, the lifting support plate blocks the light path emitted by the transmitter. At this time, the receiver cannot receive the light path, indicating that the support plate has reached the designated position. The control module then automatically shuts off the driving cylinder, greatly improving positioning accuracy. The buffer reduces vibration and impact when the driving cylinder stops, extending the service life of the driving cylinder. Furthermore, the high degree of automation allows for large-scale production, resulting in high production efficiency and reduced labor costs. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-4 This utility model provides a lifting and positioning structure for a transfer and handling device, including a supporting base plate 1, a mounting bracket 2 fixedly connected to the bottom of the supporting base plate 1, a cylinder assembly provided in the middle of the mounting bracket 2, lifting sleeves 3 provided at the four corners of the surface of the mounting bracket 2, and sliding rod assemblies slidably connected to two adjacent lifting sleeves 3, a connecting component fixedly connected to one end of the cylinder assembly, a support plate assembly fixedly connected to the top of the connecting component, side brackets 17 provided on both sides of the surface of the supporting base plate 1, multiple L-shaped fixing brackets 18 provided at the connection between the two side brackets 17 and the supporting base plate 1, and a positioning mechanism provided between the two bracket assemblies.

[0020] See Figure 2 , Figure 3 and Figure 4 Furthermore, the cylinder assembly includes a drive cylinder 6, with mounting brackets 5 fixedly connected to both sides of the drive cylinder 6, and both mounting brackets 5 are fixedly connected to the mounting bracket 2. The slide rod assembly includes two support slide rods 7, a limiting block 8, and an intermediate connecting plate 9. One end of each of the two support slide rods 7 is fixedly connected to one side of the limiting block 8, and the other end of each of the two support slide rods 7 is fixedly connected to one side of the intermediate connecting plate 9. Buffers 4 are provided on both sides of the bottom end of the mounting bracket 2, and one side of the limiting block 8 contacts and connects to one side of the buffer 4. The connecting assembly includes a rotary cylinder 10, which is mounted on the intermediate connecting plate 9. The output end of the rotary cylinder 10 is fixedly connected to a connecting support plate 11. Positioning heads 12 are fixedly connected to both ends of the top of the connecting support plate 11. Connecting blocks 13 are fixedly connected to both sides of the connection between the two positioning heads 12 and the connecting support plate 11. The support plate assembly includes a lifting support plate 14. Positioning grooves 16 are provided at both ends of the bottom of the lifting support plate 14. Fixing blocks 15 are provided on both sides of the connection between the two positioning grooves 16 and the lifting support plate 14.

[0021] In use, the output end of the drive cylinder 6 is fixedly connected to the intermediate connecting plate 9. When the drive cylinder 6 is started, it drives the intermediate connecting plate 9 to perform a lifting movement. The support slide rod 7 slides inside the lifting slide sleeve 3. The four support slide rods 7 can ensure the stability and load-bearing capacity of the lifting process. The positioning head 12 is inserted into the positioning groove 16. Then, the connecting block 13 and the fixing block 15 are connected together by bolts. At this time, the four support slide rods 7 move in the vertical direction, driving the intermediate connecting plate 9, the rotary cylinder 10, the connecting support plate 11 and the lifting support plate 14 to move up and down. The buffer 4 is installed on the mounting bracket 2. One end of the buffer 4 faces down. During the lifting movement of the drive cylinder 6, when the drive cylinder 6 stops through the positioning mechanism, the limit block 8 will contact the lower end of the buffer 4. The buffer 4 can absorb and consume kinetic energy, reduce vibration and impact, and ensure the stability and reliability of the equipment. The use of the buffer 4 can effectively reduce the impact force and protect the cylinder and the equipment. The rotary cylinder 10 can make the lifting support plate 14 rotate.

[0022] See Figure 1 Furthermore, the positioning mechanism includes multiple positioning brackets 19, which are respectively mounted on two side brackets 17. A transmitter 20 and a receiver 21 are respectively fixedly installed on one side of the two symmetrical positioning brackets 19.

[0023] In use, multiple positioning brackets 19 are divided into two parts and installed on two side brackets 17 respectively, in pairs. One bracket installs the transmitter 20 and the other installs the receiver 21. When the lifting plate 14 is lifted to a certain height, it will block the light path emitted by the transmitter 20. At this time, the receiver 21 cannot receive the light path, thereby determining whether the lifting plate 14 has moved into place.

[0024] In this embodiment, the device itself has a control module. The cargo component is placed onto the lifting support plate 14 via a third-party structure. A pressure sensor is installed on the lifting support plate 14. After detecting that an object has been placed on the lifting support plate 14, the pressure sensor sends a signal to the control module. At this time, the control module activates the drive cylinder 6, causing it to move the lifting support plate 14 upwards. The transmitter 20 and receiver 21 are through-beam photoelectric sensors. During the lifting process, the transmitter 20 continuously emits light to the receiver 21. Adjusting the length and other specifications of the positioning bracket 19 allows for adjustment of the distance between the transmitter 20 and receiver 21 mounted on the positioning bracket 19 and the supporting base plate 1. This adjustment is possible according to the required lifting height of the lifting support plate 14. When the lifting support plate 14 rises to the level of the transmitter 20 and receiver 21... During this period, the light path of transmitter 20 is blocked. Because receiver 21 cannot receive the light, it sends a signal to the control module. Then, the control module shuts down the drive cylinder 6. At this time, the lifting support plate 14 is positioned in the set position. It should be noted that this utility model is a lifting and positioning structure for a transfer and handling device.

Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
