Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, specifically to a clamp for transferring plate-shaped materials. Background Technology

[0002] Currently, the clamps widely used in the industry for transferring sheet materials are mainly divided into two categories: one is the jaw clamp, which uses the friction between the jaws and the surface of the sheet material to clamp and transfer the material. However, this friction-dependent transfer method has obvious drawbacks: when the material surface is relatively smooth, contains oil, or has high humidity, the friction will decrease significantly, making it very easy for the sheet to slip during transfer, causing material damage or even safety accidents; at the same time, in order to ensure sufficient friction, the jaws often need to apply a large clamping force to the material, which can easily cause deformation, surface scratches, and other problems for some softer materials (such as plastic sheets, thin wood sheets) or easily damaged surfaces (such as coated steel sheets, glass sheets), affecting the subsequent use of the material.

[0003] Another commonly used transfer method is magnetic transfer, which uses magnetic force to attract plates made of magnetic materials such as ferrite. However, this method has strict material limitations; it is only applicable to magnetic materials and is completely unsuitable for non-magnetic materials such as aluminum alloy plates, plastic plates, glass plates, and wood panels, greatly limiting its application in diverse material transfer scenarios. Furthermore, magnetic transfer is usually difficult to achieve stacked transfer of multiple plates because the magnetic force weakens rapidly with the number of plates, and magnetic interference between adjacent plates can lead to unstable stacking, often requiring transfer one plate at a time, resulting in low efficiency.

[0004] Therefore, in view of the shortcomings of existing plate material transfer fixtures in terms of stability, applicability and transfer efficiency, it has become an urgent need in the industry to develop a new type of transfer fixture that can overcome the above defects. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a fixture for transferring sheet materials. The fixture uses flip-type claws to lift the sheet material from below, enabling material transfer. Compared to claw-type fixtures that rely on friction for transfer, this lifting method is more stable and significantly reduces the risk of sheet materials falling or deforming. Furthermore, unlike magnetic transfer methods, it is not limited by the material type and allows for the simultaneous transfer of multiple stacked sheets.

[0006] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a clamp for transferring plate-like materials, including a crossbeam, with vertically mounted cantilever arms at both ends of the crossbeam, a flip-type chuck at the lower part of the cantilever arms, a fixed plate inside the crossbeam, a transmission chain between the fixed plate and the flip-type chuck, an adjusting sprocket located inside the transmission chain inside the crossbeam, and a drive source for driving the adjusting sprocket to move laterally inside the crossbeam.

[0007] As a further improvement to the above technical solution:

[0008] The drive source includes a motor located in the middle of the crossbeam, and the output end of the motor is provided with a drive gear, and the drive gear is provided with racks on both sides.

[0009] One end of the rack is meshed with the drive gear, and the other end is provided with a transfer frame connected to the adjusting sprocket. The side wall of the crossbeam is provided with slide rails located on both sides of the transfer frame.

[0010] The middle part of the adjusting sprocket is provided with a cross brace that connects to the end of the adapter frame. Both ends of the cross brace extend to the outside of the cross beam. The side wall of the cross beam is provided with a through groove corresponding to the position of the cross brace.

[0011] The cantilever is provided with a guide sprocket located on the outside of the transmission chain in the middle.

[0012] The lower part of the cantilever is provided with a positioning shaft, and the positioning shaft is provided with a bearing seat for mounting the flip-type chuck. Below the positioning shaft is a reset device connected to the flip-type chuck.

[0013] The reset device includes a mounting plate, and a reset spring is provided between the mounting plate and the flip-type chuck.

[0014] The positioning shaft is equipped with two symmetrically distributed flip-type jaws, and each flip-type jaw is equipped with a transmission chain.

[0015] The beneficial effects of this utility model embodiment are as follows: The clamp for transferring plate-shaped materials includes a crossbeam, with vertically mounted cantilever arms at both ends of the crossbeam. A flip-type chuck is provided at the lower part of the cantilever arms. A fixed plate is provided inside the crossbeam, and a transmission chain is provided between the fixed plate and the flip-type chuck. An adjusting sprocket is provided inside the crossbeam and located inside the transmission chain. A drive source for driving the adjusting sprocket to move laterally is provided inside the crossbeam. The material is transferred by lifting the plate-shaped material from below using the flip-type chuck. Compared with the chuck-type clamp that uses friction for transfer, the lifting method is more stable and can significantly reduce the phenomenon of plate falling or deformation. At the same time, compared with the magnetic transfer method, there is no limitation on the material of the material, and multiple plates can be stacked and transferred at one time.

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figure 1-4As shown, the clamp for transferring plate materials in this embodiment includes a crossbeam 1, with vertically mounted cantilever arms 2 at both ends of the crossbeam 1. A flip-type gripper 3 is located at the lower part of each cantilever arm 2. A fixing plate 4 is located inside the crossbeam 1, and a transmission chain 5 connects the fixing plate 4 and the flip-type gripper 3. An adjusting sprocket 6 is located inside the crossbeam 1 and inside the transmission chain 5. A drive source 7 is located inside the crossbeam 1 to drive the adjusting sprocket 6 to move laterally. The drive source 7 drives the adjusting sprocket 6 to move along the length of the crossbeam 1, thereby changing the state of the transmission chain 5. For example, in the initial position, the center of the adjusting sprocket 6 coincides with the center of the flip-type gripper 3. At this time, the flip-type gripper 3 remains drooping under gravity, and the entire transmission chain 5... The angle between the upper and lower halves of the transmission chain 5 is 90 degrees. When in the working position, the drive source 7 pushes the adjusting sprocket 6 to move outward. At this time, the angle between the upper and lower halves of the transmission chain 5 is 70-80 degrees, while the total length of the transmission chain 5 remains unchanged. Therefore, the lower end of the transmission chain 5 will be lifted upward, causing the end of the flip-type chuck 3 to rotate upward and support the bottom of the plate material. Compared with the direction of transmission that relies on friction or electromagnets to transport plate materials, the flip-type chuck 3 can transfer multiple plates at one time. The lifting method can ensure that the plates are more stable and will not fall during the transfer process. Moreover, there are no restrictions on the material of the plates, and it can be applied to more types of plate transfer operations.

[0023] The drive source 7 includes a motor 8 located in the middle of the crossbeam 1. The output end of the motor 8 is equipped with a drive gear 9. The drive gear 9 has racks 10 on both sides. One end of the racks 10 is meshed with the drive gear 9, and the other end is equipped with a transfer frame 11 connected to the adjusting sprocket 6. The inner side wall of the crossbeam 1 is equipped with slide rails 12 located on both sides of the transfer frame 11. By rotating the drive gear 9, the racks 10 on both sides are driven to move laterally, thereby completing the upward flipping of the flipping claws 3 at the bottom of the two cantilever arms 2, supporting the bottom of the plate material and completing the transfer operation.

[0024] The middle part of the adjusting sprocket 6 is provided with a cross brace 13 connected to the end of the adapter frame 11. The two ends of the cross brace 13 extend to the outside of the cross beam 1. The side wall of the cross beam 1 is provided with a through groove 14 corresponding to the position of the cross brace 13. The through groove 14 can limit the sliding distance of the cross brace 13 and prevent the plate from falling after the flip-type claw 3 flips too much.

[0025] The middle part of the cantilever 2 is provided with a guide sprocket 15 located outside the transmission chain 5. The height of the guide sprocket 15 can be adjusted according to the flip angle of the flip-type pawl 3. The design of the guide sprocket 15 can provide secondary guidance for the movement of the transmission chain 5, and avoid deviation when the transmission chain 5 moves longitudinally.

[0026] The lower part of the cantilever 2 is provided with a positioning shaft 16, and a bearing seat 17 for mounting the flip-type chuck 3 is provided on the positioning shaft 16. Below the positioning shaft 16 is a reset device connected to the flip-type chuck 3. The reset device includes a mounting plate 18, and a reset spring 19 is provided between the mounting plate 18 and the flip-type chuck 3. The reset device is designed to help the flip-type chuck 3 reset after the material transfer is completed.

[0027] The positioning shaft 16 is equipped with two symmetrically distributed flip-type claws 3, each of which is equipped with a transmission chain 5. Multiple flip-type claws 3 can also be installed to increase the contact points with the material, distribute the force, and increase the stability of the lifting.
