DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following combines the attached Figures 1-4 to further illustrate the present utility model.

[0023] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / linkage relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present utility model can be interactively combined without conflicting with each other.

[0024] Referring to Figure 1 and Figure 2 the present utility model provides an auxiliary coil loading and unloading device for assisting the loading of the coil 5. It includes mounting side plates 1, air expansion chucks 4 and coil changing auxiliary plates 2. The mounting side plates 1 are the base of the entire device for mounting and fixing each component. The two mounting side plates 1 are arranged oppositely, and each component is installed between the two mounting side plates 1; the air expansion chucks 4 are arranged on the mounting side plates 1, and the air expansion chucks 4 on the two mounting side plates 1 are arranged oppositely. The air expansion chucks 4 are used to clamp the coil 5 conveyed to the auxiliary loading and unloading device for operations such as winding and coating; the coil changing auxiliary plate 2 is arranged on the mounting side plate 1 and is located below the air expansion chuck 4 for supporting the coil 5 and conveying it to the air expansion chuck 4. The specific structure and working principle of the air expansion chuck 4 refer to the prior art and will not be elaborated here.

[0025] Embodiment 1

[0026] Furthermore, a driving member is arranged on the mounting side plate 1. The driving member is connected to the coil changing auxiliary plate 2 to drive the coil changing auxiliary plate 2 to move towards or away from the coil 5. The driving member is a driving cylinder 3. A driving mounting seat 12 is fixedly connected to the mounting side plate 1. The driving cylinder 3 is fixedly connected to the driving mounting seat 12, and the piston rod of the driving cylinder 3 is connected to the coil changing auxiliary plate 2. When the piston rod of the driving cylinder 3 extends, it can push the coil changing auxiliary plate 2 away from the coil 5 to facilitate the smooth progress of the winding and unwinding operations.

[0027] Referring to Figures 2 to 4, Further, the output shaft of the driving cylinder 3 is rotatably connected with a connecting head 31. The connecting head 31 is in a "Y" - shaped structure. A connecting through - hole 21 is opened on the side of the coil - changing auxiliary plate 2 close to the driving cylinder 3. A connecting shaft 32 is rotatably connected in the connecting through - hole 21. Both ends of the connecting shaft 32 are fixedly connected to the connecting head 31, that is, the end of the coil - changing auxiliary plate 2 is rotatably connected to the connecting head 31 through the connecting shaft 32. A fixed seat 13 is fixedly connected to the mounting side plate 1. One end of the coil - changing auxiliary plate 2 far from the driving cylinder 3 is rotatably connected to the fixed seat 13.

[0028] During the process of the piston rod of the driving cylinder 3 extending or retracting, since the driving cylinder 3 is fixedly arranged, the piston rod of the driving cylinder 3 extends or retracts on a vertical line. At the same time, one end of the coil - changing auxiliary plate 2 far from the driving cylinder 3 rotates on the fixed seat 13, one end of the coil - changing auxiliary plate 2 close to the driving cylinder 3 is rotatably connected to the connecting head 31, and the connecting head 31 is rotatably connected to the piston rod of the driving cylinder 3 to ensure the smooth progress of the action of the coil - changing auxiliary plate 2 moving away from or approaching the coil 5.

[0029] In order to accurately convey the coil 5 to the position of the air - expanding chuck 4, a positioning block 22 is fixedly connected to the coil - changing auxiliary plate 2. The positioning block 22 is arranged on the side of the coil - changing auxiliary plate 2 close to the driving cylinder 3 and is located below the air - expanding chuck 4. When assisting in loading and unloading the coil through the auxiliary coil - loading and unloading device, the coil 5 is placed on the coil - changing auxiliary plate 2 by a transporting mechanism such as an AGV cart or a forklift. Then, the coil 5 is pushed, so that the coil 5 rolls along the coil - changing auxiliary plate 2 to the positioning block 22. The positioning block 22 tightly positions the coil 5, enabling the coil 5 to accurately roll to the air - expanding chuck 4, so that the roller shaft of the coil 5 can be aligned with the air - expanding chuck 4, effectively improving the accuracy of placing the coil 5.

[0030] When loading is required, the coil 5 is placed on the coil - changing auxiliary plate 2 by a handling mechanism such as an AGV cart or a forklift. The coil - changing auxiliary plate 2 supports the roller shafts at both ends of the coil 5. Then, the coil 5 is pushed until the coil 5 abuts against the positioning blocks 22 on both sides. At this time, the air - expanding chuck 4 is started to tighten and fix both ends of the coil 5. Then, the driving cylinder 3 is started, and the piston rod of the driving cylinder 3 extends to push the coil - changing auxiliary plate 2 away from the coil 5. At this time, the loading work is completed. When unloading is required, first start the driving cylinder 3 so that the piston rod of the driving cylinder 3 retracts, driving the coil - changing auxiliary plate 2 to reset and contact the coil 5. At this time, the air - expanding chuck 4 contracts to release the coil 5, and the coil 5 is disengaged from the tension of the air - expanding chuck 4. The coil 5 can be pushed out, and then the coil 5 is removed by a handling mechanism such as an AGV cart or a forklift. The coil - changing auxiliary plate 2 is set to load and unload the coil 5, effectively liberating manual labor and reducing labor costs. With the setting of the positioning block 22, it can reduce the influence of human judgment on the installation position of the coil 5, can accurately position the coil 5, ensure the efficiency and accuracy of coil loading and unloading, and ensure the quality of winding and unwinding.

[0031] Refer to Figure 3 Figure 3 , further, a buffer inclined surface 221 is obliquely formed on the positioning block 22. The buffer inclined surface 221 inclines towards the driving cylinder 3. By providing the buffer inclined surface 221, when the coiled material 5 rolls to the positioning block 22, the buffer inclined surface 221 plays a buffering role in the rolling of the coiled material 5. The buffer inclined surface 221 obliquely formed on the positioning block 22 can effectively reduce the possibility of damage to the coiled material 5 caused by the impact between the coiled material 5 and the positioning block 22 while positioning the coiled material 5.

[0032] Refer to Figure 4 Figure 4 , further, a cushion block 23 is detachably arranged on the coil-changing auxiliary plate 2. The cushion block 23 is detachably fixed on the side of the coil-changing auxiliary plate 2 facing the air-expanding chuck 4. When using a small-sized reel, the cushion block 23 is installed on the coil-changing auxiliary plate 2 to raise the small-sized reel, so that the air-expanding chuck 4 can also be aligned with the roller shaft of the small-sized reel, realizing accurate feeding. Among them, the thickness of the cushion block 23 can be adaptively selected according to actual needs. The setting of the cushion block 23 enables the auxiliary coil loading and unloading device to be applicable to different-sized reels, which is beneficial to improving the application range of the device.

[0033] In addition, in order to ensure the stability of the whole device, a plurality of positioning cross beams 11 are fixedly connected between the two mounting side plates 1. Specifically, in this embodiment, four positioning cross beams 11 are fixedly connected between the two mounting side plates 1, and the four positioning cross beams 11 are symmetrically arranged in pairs at the top and bottom of the mounting side plates 1.

[0034] Embodiment 2

[0035] The difference between Embodiment 2 and Embodiment 1 is that: the driving cylinder 3 is rotatably connected to the mounting side plate 1, and the connecting head 31 is fixedly connected to the piston rod of the driving cylinder 3. Specifically, a driving mounting seat 12 is fixedly connected to the mounting side plate 1. The driving cylinder 3 is rotatably connected to the driving mounting seat 12. The connecting head 31 is fixedly connected to the piston rod of the driving cylinder 3. The connecting head 31 is in a "Y"-shaped structure. One end of the connecting head 31 away from the driving cylinder 3 is fixedly connected with a connecting shaft 32. A connecting through hole 21 is formed at one end of the coil-changing auxiliary plate 2 close to the driving cylinder 3. The connecting shaft 32 is rotatably connected to the connecting through hole 21. A fixing seat 13 is fixedly connected to the mounting side plate 1. One end of the coil-changing auxiliary plate 2 away from the driving cylinder 3 is rotatably connected to the fixing seat 13.

[0036] Since the driving cylinder 3 is rotatably connected to the driving mounting base 12, during the process that the piston rod of the driving cylinder 3 extends or retracts to drive the coil-changing auxiliary plate 2 to move, the driving cylinder 3 will rotate on the driving mounting base 12. At the same time, the end of the coil-changing auxiliary plate 2 far from the driving cylinder 3 will rotate on the fixed seat 13, and the end of the coil-changing auxiliary plate 2 close to the driving cylinder 3 rotates on the connecting head 31, so as to ensure the smooth progress of the movement of the coil-changing auxiliary plate 2 away from or close to the coil material 5.

[0037] The implementation process of the present utility model is as follows:

[0038] When feeding is required (i.e., when changing the coil during unwinding), first, the coil material 5 is placed on the coil-changing auxiliary plate 2 by a handling mechanism such as an AGV cart or a forklift, and the coil material 5 is pushed to the positioning block 22 for positioning the coil material 5. Then, the air-expansion chuck 4 tightens the coil material 5, and the piston rod of the driving cylinder 3 extends to drive the coil-changing auxiliary plate 2 away from the coil material 5; when discharging is required (i.e., when changing the coil during winding), the piston rod of the driving cylinder 3 retracts, the air-expansion chuck 4 releases the coil material 5, and then the coil material 5 is manually pushed out along the coil-changing auxiliary plate 2, and the coil material 5 is taken off by an AGV cart or a forklift; when using a reel with a smaller size, a cushion block 23 can be installed on the coil-changing auxiliary plate 2 first, and then the above operations are carried out.

[0039] The above is a specific description of the preferred embodiment of the present utility model. However, the present utility model is not limited to the described embodiment. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
