Description

Technical Field

[0001] This utility model relates to the field of transfer equipment, specifically a material transfer vehicle. Background Technology

[0002] Currently, in the silicon wafer manufacturing industry, the market is mainly divided into two categories: monocrystalline and polycrystalline. With the development of industry technology, monocrystalline silicon wafers have become the mainstream in the market, accounting for more than 90% of the market share. Before the slicing process of monocrystalline silicon wafers, the monocrystalline square rod, plastic pad, and crystal carrier must be glued together as a whole according to predetermined standards so that they can be cut by the slicing machine later. The crystal carrier assembly after bonding is relatively heavy, usually about 80 kg, so the operational efficiency and safety of its transportation process have become the focus of daily attention for manufacturing companies.

[0003] In existing transfer processes, flat-panel transfer vehicles are commonly used for handling. When using slings to lift crystal cascade modules onto the flat support plate of the transfer vehicle, the slings are difficult to pull out directly after being compressed because the support surface is a complete flat plane. Operators have to manually lift one end of the module to remove the slings, which poses a high safety risk. If the operation is not careful, the module can easily slip or injure a person's hand, causing a safety accident.

[0004] To alleviate this problem, one existing improvement is to design the width of the support plate to be smaller than the length of the crystal traction assembly, leaving both ends of the assembly suspended and providing operational space for sling removal. However, due to the considerable length of the crystal traction assembly itself, operators still need to walk around to both ends of the transfer vehicle to remove the slings attached to the ends of the assembly, making the overall operation cumbersome and limiting transfer efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a material transfer vehicle to solve the problem that the lifting straps at both ends of long strip materials affect work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A material transfer vehicle includes a carrying plate and a support frame. The carrying plate is horizontally fixed on the top of the support frame, and the bottom of the support frame is provided with several rollers. It also includes a telescopic rod, two push rods, several movable rods, and a connecting rod. The two push rods are respectively arranged on both sides of the long side of the carrying plate, with the top surface of the push rods flush with the top surface of the carrying plate. Several horizontally arranged sliding rods are arranged side-by-side on the push rods, with the push rods and sliding rods perpendicular to each other. The sliding rods are slidably connected to the carrying plate. The telescopic rod is located in the middle of the bottom surface of the carrying plate, with its fixed end fixedly connected to the carrying plate and its movable end extending downwards. The connecting rod is parallel to the sliding rods, and its middle part is fixedly connected to the movable end. One end of the movable rod is hinged to the push rod, and the other end of the movable rod is hinged to the connecting rod.

[0007] The working principle of this utility model is as follows: by moving the push rod laterally, the sling is pushed laterally to the outside of the material, and the overhead crane can then rise to a higher height to carry out subsequent actions.

[0008] Preferably, one to three telescopic rods are provided, and the telescopic rods are spaced apart along the long side of the bearing plate. The connecting rods and push rods are divided into several segments corresponding to the number of telescopic rods. Two or more movable rods are provided between each segment of connecting rod and each segment of push rod. Two or more sliding rods are fixedly provided on each segment of push rod.

[0009] Preferably, a plurality of baffles are fixedly provided below the push rod, and the baffles are arranged vertically.

[0010] Preferably, the control switch for the telescopic rod is independently set and located on the short side of the support plate.

[0011] Preferably, the top surface of the bearing plate has several grooves arranged side by side along the long side, and the baffle and the grooves are positioned correspondingly.

[0012] Preferably, a T-shaped traction rod is provided on one side of the support frame.

[0013] Preferably, the support plate has several sliding holes on both sides, and the sliding rod is adapted to the sliding holes.

[0014] Preferably, the bottom of the support frame is provided with a fixing plate, the fixing plate is provided with a mobile power supply, and the telescopic rod is an electric structure, with the mobile power supply and the telescopic rod being electrically connected.

[0015] Preferably, the bottom of the bearing plate is fixedly provided with several vertical guide rods, and several guide sleeves are provided on the connecting rods, with the guide rods and guide sleeves slidingly engaged.

[0016] Preferably, the top surface of the push rod is 1mm-3mm lower than the top surface of the bearing plate.

[0017] Compared with existing technologies, the technical solution of this application has the following technical advantages: After the material is hoisted into place, the overhead crane is operated to loosen the sling and the material. Subsequently, the telescopic rod is controlled to retract, and through the linkage mechanism composed of the connecting rod and the movable rod, the sliding rod is driven to move the push rods on both sides outward synchronously. The push rods push the loosened sling outward from the bottom of the material, separating it from the material. At this time, the overhead crane can be raised to directly retract the sling, and the workers do not need to go around to both ends of the material; all operations can be completed in place. This saves time and improves work efficiency. Attached Figure Description

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] like Figure 1 , 2As shown, a material transfer vehicle includes a support plate 10 and a support frame 2. The support plate 10 is horizontally fixed on the top of the support frame 2. The bottom of the support frame 2 is provided with several rollers. It also includes a telescopic rod 4, two push rods 7, several movable rods 6, and a connecting rod 5. The two push rods 7 are respectively arranged on both sides of the long side of the support plate 10, with the top surface of the push rods 7 flush with the top surface of the support plate 10. Several horizontally arranged sliding rods 11 are arranged side-by-side on the push rods 7, perpendicular to each other. The sliding rods 11 are slidably connected to the support plate 10. The telescopic rod 4 is located in the middle of the bottom surface of the support plate 10. The fixed end of the telescopic rod 4 is fixedly connected to the support plate 10, and the movable end of the telescopic rod 4 extends downward. The connecting rod 5 is parallel to the sliding rods 11, and the middle part of the connecting rod 5 is fixedly connected to the movable end. One end of the movable rod 6 is hinged to the push rod 7, and the other end of the movable rod 6 is hinged to the connecting rod 5. Initially, the telescopic rod 4 is extended, and the push rod 7 is in contact with the side of the support plate 10. When the material 1 on the sling falls onto the support plate 10, the telescopic rod 4 retracts, driving the movable rod 6 via the connecting rod 5. The movable rod 6 then pushes the push rod 7 laterally, which in turn pushes the sling off the material 1. The gantry crane can then rise and move to the next workstation. This automates the transfer of material 1, improving handling efficiency and operational safety. The sling has loops at both ends, which fit over the ends of the material.

[0024] Preferably, one to three telescopic rods 4 are provided, spaced apart along the long side of the bearing plate 10. The connecting rods 5 and push rods 7 are divided into several segments corresponding to the number of telescopic rods 4. Two or more movable rods 6 are provided between each segment of connecting rod 5 and each segment of push rod 7. Two or more sliding rods 11 are fixedly provided on each segment of push rod 7. In this embodiment, the longer push rods 7 and connecting rods 5 are divided into several segments corresponding to multiple telescopic rods 4, and an independent connecting rod and sliding system is provided between each segment. When material 1 is placed in the corresponding position, only the corresponding push rod 7 needs to be moved, reducing energy consumption.

[0025] Preferably, a plurality of baffles 8 are fixedly installed below the push rod 7, and the baffles 8 are vertically arranged. After the material 1 is placed on the support plate 10, the sling will continue to descend, thereby slackening with the material 1. When the sling descends too much, the baffles 8 are set to increase the control range of the push rod 7.

[0026] Preferably, the control switch for the telescopic rod 4 is independently set and located on the short side of the bearing plate 10, making it easy for workers to operate from the short side.

[0027] Preferably, the top surface of the support plate 10 has several grooves arranged side by side along its long side, and the baffle 8 corresponds to the position of the grooves. In this embodiment, the grooves are relatively shallow, making it easier for workers to observe the placement position of the materials.

[0028] Preferably, a T-shaped traction rod 9 is provided on one side of the support frame 2. After the material 1 is placed, the staff pulls the transfer vehicle to move it.

[0029] Preferably, the bearing plate 10 has a plurality of sliding holes 12 on both sides, and the sliding rod 11 is adapted to the sliding holes 12.

[0030] Preferably, a fixing plate 3 is provided at the bottom of the support frame 2, and a mobile power supply is provided on the fixing plate 3. The telescopic rod 4 is an electric structure, and the mobile power supply and the telescopic rod 4 are electrically connected. Configuring the mobile power supply to power the electric telescopic rod 4 eliminates the transport vehicle's dependence on external power sources and cables, achieving complete self-driving of the pushing operation and significantly improving the equipment's independence and ease of operation.

[0031] Preferably, the bottom of the support plate 10 is fixedly provided with several vertical guide rods, and the connecting rod 5 is provided with several guide sleeves, with the guide rods and guide sleeves slidingly engaged. The sliding engagement between the guide rods and guide sleeves effectively limits the horizontal offset and rotation of the connecting rod 5, ensuring the linearity and synchronization accuracy of the push rod 7 movement when the telescopic rod 4 is driven.

[0032] Preferably, the top surface of the push rod 7 is 1mm-3mm lower than the top surface of the bearing plate 10, which effectively avoids interference or friction between the push rod 7 and the bottom of the material 1 during operation, ensuring the smoothness and reliability of the mechanism's operation.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
