[0002] Light guide plates generally refer to high-tech plates that are made through a series of processes such as injection molding and cutting, and have extremely high reflectivity and do not absorb light.

[0003] However, in the process of injection molding the semi-finished products of the light guide plates and transporting them to the cutting mechanism, due to the existence of the "punching holes" in the injection mold, there may be columnar objects on the surface of the semi-finished products after injection molding, and due to the residual temperature of the hot injection molding, the semi-finished products may have wire drawing during the transfer work. When these wire-drawn columns solidify, they are very likely to interfere with the transfer mechanism or the cutting mechanism during the transfer process, resulting in the semi-finished products failing to enter the specified position, thereby affecting the production efficiency of the light guide plate.

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment proposes a light guide plate transfer mechanism, including a first manipulator 1 and a second manipulator 2 for transferring semi-finished products. The first manipulator 1 takes the semi-finished product out of the injection molding mechanism and transfers it to the second manipulator 2 located in the cutting mechanism. A shearing structure 3 is provided between the first manipulator 1 and the second manipulator 2. If a semi-finished columnar object that is about to enter the cutting environment shows a wire drawing phenomenon, the wire drawing portion is sheared off by the shearing structure 3. The shearing structure 3 is fixedly connected to the casing surface of the cutting mechanism close to the first manipulator 1. The shearing structure 3 includes a shearing seat 31 and a pair of scissors 32. A driving component 33 for driving the scissors 32 to perform shearing is provided between the shearing seat 31 and the scissors 32. That is, the shearing structure 3 in this embodiment drives the scissors 32 to shear off the wire drawing portion of the columnar object, thereby preventing the semi-finished product from interfering with the transfer mechanism or the cutting mechanism during the transfer process, ensuring that the semi-finished product can enter the specified position, and ensuring the production efficiency of the light guide plate.

[0030] like Figure 6 , Figure 8As shown, the driving assembly 33 includes a pressure chamber 331, a first piston rod 332, and a linkage frame 333 for linking the scissors 32 with the first piston rod 332. The pressure chamber 331 is located at one end of the shear seat 31 away from the scissors 32. The first piston rod 332 is slidably connected in the pressure chamber 331. The linkage frame 333 is located between the pressure chamber 331 and the scissors 32. The pressure chamber 331 includes two pressure valves. By injecting gas or hydraulic oil into one of the pressure valves, the pressures at both ends of the pressure chamber 331 are made different, thereby driving the first piston rod 332 to slide, so that the linkage frame 333 transmits force to the scissors 32, so that the scissors 32 perform shearing.

[0031] The linkage frame 333 includes a plurality of movable rods 3331, a hinge shaft 334 is provided on the first piston rod 332, and each movable rod 3331 is hinged on the hinge shaft 334. The scissors 32 include two blades 321, a fixed shaft 336 is provided on the shear seat 31, and the fixed shaft 336 is fixedly connected to the shear seat 31. Adjacent blades 321 are staggered and intersected and are hinged on the fixed shaft 336, and each movable rod 3331 is hinged to each blade 321 one by one. A rectangular structure is formed between each knife body 321 and each movable rod 3331. Since the knife body 321 can only rotate in the shear seat 31 and its position has been completely fixed in the shear seat 31, that is, when the first piston rod 332 is displaced by the internal pressure of the pressure chamber 331, it drives each movable rod 3331 to move, which will cause the rectangular structure to deform, and the distance between the two ends of the rectangular structure will gradually shorten or lengthen. Because the rectangular structure is a closed frame structure, its area will not change due to deformation. Therefore, the distance between the two sides of the rectangular structure, that is, the connection point between each movable rod 3331 and the knife handle 322, will lengthen or shorten according to the movement of the first piston rod 332, thereby driving the knife body 321 to rotate. Because the two knife bodies 321 are hinged to each other, the two knife bodies 321 will gradually move closer or farther away under the movement of the first piston rod 332, thereby completing the shearing of the wire drawing part of the column.

[0032] At the same time, in order to facilitate the hinge between the movable rod 3331 and the blade body 321, a handle 322 is provided at one end of each blade body 321 close to the movable rod 3331, and each blade body 321 and the handle 322 are integrally formed, the handle 322 is a ring structure, and a linkage rod 335 is provided on each movable rod 3331, and the linkage rod 335 is embedded in the inner ring of the handle 322, thereby ensuring the stability of the hinge structure of the movable rod 3331 and the blade body 321 in an embedded manner.

[0033] It is preferred to inject gas into the pressure chamber 331 in the present embodiment, and utilize the gas pressure to make the first piston rod 332 move back and forth so that the scissors 32 can also continuously perform shearing actions, so that the present embodiment has cyclicity. At the same time, how to inject gas into the pressure chamber 331 depends on the selected control system, which will not be elaborated in the present embodiment.

[0034] like Figure 6-7 As shown, the hinge shaft 334 in this embodiment is located at one end of the first piston rod 332 close to the knife handle 322, so as to avoid the distance between the movable rod 3331 and the knife handle 322 being too long, resulting in the linkage rod 335 being required to be set longer, thereby reducing the possibility of deformation and bending of the linkage rod 335 after being driven by the first piston rod 332, and ensuring the stability of the linkage rod 335 structure;

[0035] The hinge shaft 334 includes a hinge part 3341 and a limiting part 3342. The diameter of the limiting part 3342 is larger than the diameter of the hinge part 3341. The limiting part 3342 and the hinge part 3341 are integrally formed. The hinge part 3341 is located between the limiting part 3342 and the first piston rod 332 and is fixedly connected to the first piston rod 332. This prevents the movable rod 3331 from detaching from the hinge shaft 334 under the reciprocating operation of the first piston rod 332, causing the linkage frame 333 to be unable to link the scissors 32 and the driving assembly 33, thereby ensuring the stability of the overall structure of this embodiment and reducing the maintenance frequency.

[0036] Example 2

[0037] like Figure 2 , Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0038] A sliding structure 4 is provided for pushing the shearing structure 3 to move. The shearing structure 3 is displaced by the sliding structure 4, so that when the first manipulator 1 and the second manipulator 2 are switching, the shearing structure 3 can be away from the first manipulator 1 and the second manipulator 2, avoiding the shearing structure 3 from interfering with the switching work between the first manipulator 1 and the second manipulator 2, which not only saves the need to set up an additional avoidance procedure for the first manipulator 1 and the second manipulator 2, but also ensures the safety of the operation of this embodiment.

[0039] The sliding structure 4 in this embodiment includes a pressure cylinder 41 and a second piston rod 42. The second piston rod 42 is slidingly connected in the pressure cylinder 41. The pressure cylinder 41 also includes two air valves. The shearing structure 3 is fixedly connected to the second piston rod 42, that is, the sliding structure 4 also utilizes air pressure and other pressures to drive the second piston rod 42 to reciprocate, thereby avoiding the first manipulator 1 and the second manipulator 2. The pressure driving structure is reliable and can ensure that there is sufficient force to push the shearing structure 3, thereby improving the movement efficiency of the shearing structure 3, thereby ensuring the practicality of this embodiment.

[0040] Example 3

[0041] like Figure 3 to Figure 6 As shown, based on the same concept as the above-mentioned embodiment 2, this embodiment further proposes:

[0042] The shearing structure 3 is provided with a cooling assembly 5 to prevent the shearing structure 3 from being unable to completely shear off the wire drawing portion of the column and its wire drawing portion due to the internal residual temperature when the shearing structure 3 shears off the column, thereby affecting the shearing efficiency.

[0043] The cooling assembly 5 includes a fan 51 and an air supply pipe 52. The air outlet of the fan 51 is connected to the air supply pipe 52. The air supply pipe 52 includes an air supply port 521 for exhausting air. The air supply port 521 is located above the scissors 32. The air supply pipe 52 is fixedly connected to the shear seat 31. That is, the cooling assembly 5 in this embodiment generates cold air through the fan 51. The cold air cools and hardens the column and its drawing part, so that the shearing structure 3 can be completely cut off at one time when shearing the column and its drawing part.

[0044] The fan 51 in this embodiment is preferably a small centrifugal fan, so that the fan 51 has a higher air volume and wind speed, thereby ensuring the cooling efficiency of the cooling component 5.

[0045] The air supply pipe 52 includes a connecting portion 522 and a fixing portion 523. The connecting portion 522 is connected to the fixing portion 523 and is located between the fixing portion 523 and the fan 51. The connecting portion 522 is composed of a bellows, so that the air supply pipe 52 can be deformed under the action of the sliding structure 4, thereby shortening the length of the air supply pipe 52 while ensuring that the shear structure 3 can be pushed normally by the sliding structure 4, reducing economic costs and avoiding the air supply pipe 52 from interfering with the movement of the shear structure 3. The fixing portion 523 is fixedly connected to the shear seat 31, and the air supply port 521 is located at the fixing portion 523, that is, no matter how the sliding structure 4 pushes the shear seat 31, the air supply port 521 can always be aligned with the scissors 32, ensuring that the cooling effect of the cooling assembly 5 can always be maintained.

[0046] The fixing portion 523 and the shear seat 31 are provided with a plurality of cable ties 6, each of which is a ring structure. The fixing portion 523 and the shear seat 31 are both located in the inner ring of the cable tie 6 and are both in contact with the inner ring of the cable tie 6. That is, in this embodiment, the air supply pipe 52 and the shear seat 31 are fixed by the cable tie 6, which fully ensures the fixing effect between the air supply pipe 52 and the shear seat 31 and is convenient for later adjustment, thereby ensuring the practicality of this embodiment.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
