As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0028] See also Figure 1-5 The embodiment of the present invention provides a lower plate clamping mechanism, including a plate clamping fixing device 10 and a base plate 20. The plate clamping fixing device 10 is arranged on the base plate 20, and the plate clamping fixing device 10 includes a first plate clamping hook 11, a driving cylinder 12, a support rod 13 and an anti-drop cylinder 14, wherein the anti-drop cylinder 14 is connected to the support rod 13; and the driving cylinder 12 is connected to the first plate clamping hook 11.

[0029] The driving cylinder 12 is used to drive the first plate clamp hook 11 to hook the plate clamp assembly 30 ; the anti-drop cylinder 14 is used to drive the support rod 13 to extend to the bottom of the first plate clamp hook 11 to support the first plate clamp hook 11 .

[0030] In this embodiment, an anti-drop cylinder 14 and a support rod 13 are added below the first plate clamp hook 11 to assist the driving cylinder 12 in supporting the first plate clamp hook 11, thereby avoiding wear of the driving cylinder 12 due to long-term use, effectively extending the service life of the driving cylinder 12, and thus extending the service life of the lower plate clamp structure as a whole.

[0031] Please continue to see Figure 1-5 In one embodiment, the first plate clamp hook 11 includes two hooks staggered one in front of the other, and the two hooks are used to hook the two ends of the plate clamp assembly 30. When the driving cylinder 12 drives the two hooks to move closer to each other, the two hooks just hook the two ends of the plate clamp assembly 30 one in front of the other, and the plate clamp assembly 30 is hooked at this time; when the driving cylinder 12 drives the two hooks to move away from each other, the two hooks are separated from the plate clamp assembly 30, and the plate clamp assembly 30 is released at this time. In this embodiment, the plate clamp fixing device 10 is arranged in the middle of the plate clamp assembly 30, and the driving cylinder 12 is controlled to realize that the first plate clamp hook 11 hooks a plate clamp assembly 30.

[0032] Please continue to see Figure 1-5 In another embodiment, the lower plate clamp mechanism includes two plate clamp fixing devices 10. The two plate clamp fixing devices 10 are arranged opposite to each other. The two plate clamp fixing devices 10 are respectively arranged at the two ends of the plate clamp assembly 30; the first plate clamp hook 11 includes two hooks that are offset one after the other, and the two hooks are offset to hook one end of the plate clamp assembly 30 together. When a driving cylinder 12 drives the two hooks to move closer to each other, so that the two hooks just hook one end of the plate clamp assembly 30 together one after the other, the other driving device is synchronously operated, and at this time, the two ends of the plate clamp assembly 30 are respectively hooked by the two plate clamp fixing devices 10, which is the state of hooking the plate clamp assembly 30; when a driving cylinder 12 drives the two hooks to move away from each other, so that the two hooks are separated from one end of the plate clamp assembly, the other driving device is synchronously operated, and at this time, the two ends of the plate clamp assembly are respectively separated from the two plate clamp fixing devices 10, which is the state of loosening the plate clamp assembly. In this embodiment, two plate clamp fixing devices 10 are arranged opposite to each other and are respectively located at the two ends of the plate clamp assembly. Two first plate clamp hooks 11 are respectively controlled by two driving cylinders to jointly hook a plate clamp assembly 30.

[0033] In one embodiment, the lower plate clamping mechanism further includes a conveying device 40 and a plate clamping mechanism 50; the conveying device 40 is used to convey the plate clamping assembly 30; wherein the plate clamping mechanism 50 moves the plate clamping assembly 30 from the conveying device 40 to the plate clamping fixing device 10.

[0034] In a specific implementation, the conveying device includes a motor 41 and a chain 42 . The motor 41 drives the chain 42 to move. Both ends of the plate clamp assembly 30 are respectively mounted on the chain 42 . The chain 42 drives the plate clamp assembly 30 to be transported.

[0035] Please continue to see Figure 1-5 The plate feeding and clamping mechanism includes a double-stroke cylinder 51, a lifting cylinder 52, a second plate clamping hook 53, a first slider 54 and a first slide rail 55; the double-stroke cylinder 51 is connected to the first slider 54, the lifting cylinder 52 is arranged on the first slider 54, and the lifting cylinder 52 is connected to the second plate clamping hook 53; the double-stroke cylinder 51 drives the first slider 54 to move along the first slide rail 55.

[0036] As can be seen from the figure, the second plate clamp hook 53 includes a connecting rod 56 and hooks located at both ends of the connecting rod 56. The first slider 54 is located in the middle of the connecting rod 56.

[0037] In this embodiment, the double-stroke cylinder 51 and the lifting cylinder 52 cooperate with each other to drive the second plate clamp hook 53 to move, thereby realizing the cycle of hooking the plate clamp assembly → moving the plate clamp assembly → putting down the plate clamp assembly.

[0038] It should be noted that, in one embodiment, the operation mode of the plate feeding clamping mechanism is as follows:

[0039] S1, the double-stroke cylinder retracts, and then the lifting cylinder descends, driving the second plate clamp hook to descend to the position of the plate clamp assembly at the conveying position (below the plate clamp assembly to be taken);

[0040] S2, the lifting cylinder rises to hook the plate clamp assembly to be taken, completing the action of hooking the plate clamp assembly;

[0041] S3, the double-stroke cylinder extends to move the hooked plate clamp assembly to the position where the plate clamp fixing device places the plate clamp assembly (above the first plate clamp hook), completing the action of moving the plate clamp assembly;

[0042] S4, the lifting cylinder descends, so that the plate clamp assembly is hooked by the first plate clamp hook, and the plate clamp assembly moves to the plate clamp fixing device, completing the action of lowering the plate clamp assembly;

[0043] Repeating steps S1-S4 is the operation mode of the plate feeding clamping mechanism.

[0044] In other embodiments, the plate clamping mechanism may also use other operating modes to complete the action cycle of hooking the plate clamping assembly → moving the plate clamping assembly → putting down the plate clamping assembly.

[0045] In one embodiment, the plate clamp fixing device includes a plurality of first plate clamp hooks 11 arranged in sequence.

[0046] In order to reduce the space of the equipment, multiple first plate clamp hooks 11 are arranged vertically at intervals, so that the plate clamp assembly 30 is continuously transferred from the conveying device 40 to the plate clamp fixing device 10 from top to bottom, and then the plate clamp fixing device 10 sends the plate clamp assembly 60 to the next process.

[0047] In one embodiment, the number of the anti-drop cylinders 14 corresponds to the number of the first plate clamping hooks 11 .

[0048] To extend the service life of the drive cylinder.

[0049] In one embodiment, the base plate is provided with a second slide rail 21 and a second slider 22 , the driving cylinder 12 is connected to the second slider 22 , and the second slider 22 can slide in the second slide rail 21 .

[0050] In a specific implementation, the driving cylinder 12 can slide to the position of the first plate clamping hook 11 that needs to be controlled, and accurately control the first plate clamping hook 11 at different positions.

[0051] Please continue to see Figure 1-5 In one embodiment, the plate clamp assembly 30 includes a round shaft 31 and a plurality of clamps 32 disposed on the round shaft 31 , and both ends of the round shaft 31 are provided with a sheath 33 .

[0052] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
