Description

Technical Field

[0001] This utility model relates to the field of slitting device technology, specifically a light guide plate slitting device. Background Technology

[0002] In the production and processing of light guide plates, large light guide plates need to be slit to facilitate their use later. Slitting is a key step to ensure the dimensional accuracy of the product. Traditional light guide plate slitting devices have obvious limitations in the positioning, adjustment and material collection stages.

[0003] On the one hand, the positioning plate is usually installed on one side of the slitting assembly to position the light guide plate. The two sides of the slitting assembly are the feeding area and the positioning and receiving area, respectively. It is inconvenient for operators to stand in the feeding area to check the adjustment of the positioning plate position. The adjustment of the distance between the positioning plate and the slitting blade depends on the operator to check back and forth on both sides of the equipment, which increases the difficulty for the operator to adjust the position of the positioning plate. On the other hand, the receiving frame is mostly an independent external structure. After the positioning plate position is adjusted, the receiving frame needs to be manually realigned at the slitting outlet. Even a slight deviation will cause the light guide plate edge to bump and fall off, resulting in product scrap. When not in use, the receiving frame needs to occupy workshop space separately, which not only makes the equipment layout messy, but also makes it easy to cause secondary damage due to personnel collisions, further restricting the continuity and safety of the production process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a light guide plate slitting device to solve the problems mentioned in the background, such as the inconvenience for operators to stand in the loading area to check the position adjustment of the positioning plate, the increased difficulty for operators to adjust the position of the positioning plate, and the inconvenience for storing the receiving box.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a light guide plate slitting device, including a slitting support base, and a slitting component and a conveyor belt component disposed on its top. The conveyor belt component is located on one side of the slitting component. The loading area and unloading area on both sides of the slitting component are respectively provided with a positioning plate and an auxiliary positioning component. The auxiliary positioning component is used to quickly determine the distance between the positioning plate and the slitting component. A receiving frame that can be stored inside the slitting support base is fixedly installed at the bottom of the positioning plate.

[0006] The auxiliary positioning component includes a first limiting plate and a second limiting plate symmetrically fixed on both sides of the top of the cutting support base. A connecting rod is slidably installed at the end of the second limiting plate. The end of the connecting rod extends through the cutting component and is fixed to the positioning plate. A scale is fixed to the side of the first limiting plate and the second limiting plate. A positioning auxiliary plate is slidably installed between the first limiting plate and the second limiting plate. The positioning auxiliary plate is fixed to the connecting rod. A driving component for driving the positioning auxiliary plate to move is provided on the cutting support base.

[0007] Preferably, the slitting assembly includes a support frame fixed to one side of the top of the slitting support base, an adsorption plate for limiting the light guide plate is fixed at the lower part of the inner end of the support frame, the top of the adsorption plate is at the same horizontal height as the top of the conveyor belt assembly, and a slitting blade located on one side of the adsorption plate is installed at the upper part of the inner end of the support frame through a drive cylinder.

[0008] Preferably, the conveyor belt assembly is provided with correction wheels on both sides. In the conveying state, the outer walls of the two sides of the light guide plate are in contact with the correction wheels on both sides to perform correction.

[0009] Preferably, the distance between the positioning auxiliary plate and the limiting plate is equal to the distance between the positioning plate and the cutting blade.

[0010] Preferably, the length of the scale is equal to the length between the first limiting plate and the second limiting plate, one end of the connecting rod is slidably connected inside the second limiting plate, and the connecting rod is symmetrically arranged on both sides of the adsorption plate.

[0011] Preferably, the drive assembly includes a mounting frame fixedly installed on top of the slitting support base, the mounting frame being located at the bottom of the conveyor belt assembly, and a transmission screw being rotatably connected inside the mounting frame.

[0012] Preferably, a rotary motor is fixedly installed on the outer wall of the mounting base frame. The output end of the rotary motor passes through the outer wall of the mounting base frame and is fixedly connected to a transmission screw. A drive plate that is slidably installed with the mounting base frame is threaded onto the outer peripheral wall of the transmission screw. Both ends of the drive plate are fixedly connected to positioning auxiliary plates symmetrically arranged on both sides.

[0013] This utility model discloses a light guide plate slitting device, which has the following beneficial effects:

[0014] 1. This utility model, through the collaborative design of the positioning plate and auxiliary positioning components, and with the cooperation of the drive component, allows operators to monitor the movement status of the positioning plate in real time in the operating area with the help of the positioning auxiliary plate and the scale, without having to travel back and forth to both sides of the equipment to check. This improves the efficiency of positioning plate adjustment and the convenience of moving the positioning plate. The setting of the auxiliary positioning component provides a basis for the standardization of the operation process. Operators do not need to rely on personal experience to judge the positioning position, but can adjust it through unified indicator parameters, ensuring the consistency of operation for different personnel, so that the width of the light guide plate remains consistent after slicing, and improving the quality of the light guide plate after slicing.

[0015] 2. This utility model uses a linkage structure between the receiving frame and the positioning plate to rigidly connect the receiving frame and the positioning plate, ensuring that the light guide plate after slitting always falls accurately into the frame, completely avoiding the problems of falling and misalignment that occur with traditional external receiving. The receiving frame moves synchronously with the positioning plate and always maintains the corresponding position with the material outlet after slitting, ensuring that the material falls accurately into the frame. The storage operation of the positioning plate and the receiving frame after use can reduce the space occupied by the slitting device, making the overall layout of the equipment more compact, improving the utilization rate of workshop space, and also reducing the risk of collision caused by the external receiving frame.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] Example 1

[0027] Because the positioning plate 5 is located in the unloading area on one side of the slitting assembly 2, it is inconvenient for operators to stand in the loading area to check the adjustment of the positioning plate 5's position. Furthermore, the receiving frames 7 are mostly independent external structures, requiring separate workshop space when not in use. This not only makes the equipment layout cluttered but also increases the risk of secondary damage due to personnel collisions. This embodiment provides a light guide plate slitting device, according to the attached... Figure 1-6 As shown, it includes a slitting support base 1, and a slitting assembly 2 and a conveyor belt assembly 3 mounted on top of it. The conveyor belt assembly 3 is located on one side of the slitting assembly 2. The loading and unloading areas on both sides of the slitting assembly 2 are respectively equipped with a positioning plate 5 and an auxiliary positioning assembly 6. The auxiliary positioning assembly 6 is used to quickly determine the distance between the positioning plate 5 and the slitting assembly 2. A receiving frame 7 that can be stored inside the slitting support base 1 is fixedly installed at the bottom of the positioning plate 5. Before slitting the light guide plate, the position of the positioning plate 5 is first adjusted by the drive assembly 8 according to the width of the light guide plate slitting, so that the distance between the positioning plate 5 and the slitting blade 23 is equal to the width of the light guide plate to be cut. Then, the operator picks up the light guide plate, aligns the front end of the light guide plate with the two side correction wheels 4, and inserts them inside, so that the outer walls of the two sides of the light guide plate are in contact with the two side correction wheels 4. For details, please refer to the attached document. Figure 1 Under the action of the conveyor belt assembly 3, the light guide plate moves towards the positioning plate 5. When the light guide plate contacts the positioning plate 5, the cutting assembly 2 is activated to cut it. The cut light guide plate falls into the receiving frame 7 for collection.

[0028] To facilitate the adjustment of the position of the positioning plate 5 in the unloading area by staff, and to address the issue of operators being unable to stand in the loading area to check the position adjustment of the positioning plate 5, such as... Figure 5 - Figure 6As shown, the auxiliary positioning component 6 includes a first limiting plate 61 and a second limiting plate 62 symmetrically fixed to the top two sides of the slitting support base 1. A connecting rod 65 is slidably installed at the end of the second limiting plate 62. The end of the connecting rod 65 extends through the slitting component 2 and is fixed to the positioning plate 5. A scale 64 is fixed to the side of the first limiting plate 61 and the second limiting plate 62. A positioning auxiliary plate 63 is slidably installed between the first limiting plate 61 and the second limiting plate 62. The positioning auxiliary plate 63 is fixed to the connecting rod 65. When it is necessary to adjust the distance between the positioning plate 5 and the slitting blade 23, the cooperation between the positioning auxiliary plate 63 and the scale 64 allows the operator to easily check the position adjustment of the positioning plate 5 without having to move to the other side of the slitting support base 1 to check the position of the positioning plate 5. With the help of the auxiliary positioning component 6, the operator can monitor the movement status of the positioning plate 5 in real time in the operating area. After adjustment, the slitting support base 1 is equipped with a drive assembly 8 that moves the positioning auxiliary plate 63. After the light guide plate is placed, the conveyor belt assembly 3 operates, driving the light guide plate forward to transport it. When the front end of the light guide plate contacts the positioning plate 5, the adsorption plate 22 located on one side of the slitting blade 23 adsorbs and fixes the light guide plate. Finally, the drive cylinder at the support frame 21 drives the slitting blade 23 to descend, thereby cutting the adsorbed and fixed light guide plate. After cutting, the conveyor belt assembly 3 continues to drive the light guide plate forward, so that the front end of the light guide plate contacts the positioning plate 5 again, and the slitting blade 23 continues to cut the light guide plate. Following this step, the light guide plate is slitted into multiple segments. The drive assembly 8 drives the symmetrically arranged auxiliary positioning assembly 6 to move, thereby pushing the positioning plate 5 to move and adjusting the distance between the positioning plate 5 and the slitting assembly 2.

[0029] Specifically, the slitting assembly 2 includes a support frame 21 fixed to one side of the top of the slitting support base 1. An adsorption plate 22 for limiting the position of the light guide plate is fixed to the lower inner end of the support frame 21. The top of the adsorption plate 22 is at the same horizontal height as the top of the conveyor belt assembly 3. A slitting blade 23 located on one side of the adsorption plate 22 is mounted on the upper inner end of the support frame 21 via a drive cylinder. It should be noted that when the drive assembly 8 adjusts the position of the positioning plate 5, the positioning plate 5 automatically opens the receiving frame 7 from inside the slitting support base 1, allowing the slitting light guide plate to automatically fall into the receiving frame 7 under its own gravity for collection. This facilitates centralized processing of the slitting light guide plate by subsequent staff. Furthermore, the length of the receiving frame 7 is greater than the length of the slitting blade 23, ensuring that the slitting light guide plate falls accurately into the receiving frame 7. For details, please refer to the appendix. Figure 3 With appendix Figure 5 When the light guide plate comes into contact with the positioning plate 5, the adsorption plate 22 adsorbs and fixes the cut part of the light guide plate, making it easier to cut the light guide plate.

[0030] To improve the slitting quality of the light guide plate, such as Figure 4 As shown, the conveyor belt assembly 3 is provided with correction wheels 4 on both sides. During the conveying process, the outer walls of the two sides of the light guide plate are in contact with the correction wheels 4 to correct the deviation. This can correct the movement trajectory of the light guide plate, ensure that the light guide plate moves horizontally, prevent the light guide plate from tilting, and ensure that the front end of the light guide plate is in a horizontal contact with the positioning plate 5, thereby improving the quality of the light guide plate after slitting.

[0031] The distance between the positioning auxiliary plate 63 and the first limiting plate 61 is equal to the distance between the positioning plate 5 and the slitting blade 23. The length of the scale 64 is equal to the length between the first limiting plate 61 and the second limiting plate 62. One end of the connecting rod 65 is slidably connected inside the second limiting plate 62, and the connecting rod 65 is symmetrically arranged on both sides of the adsorption plate 22. When the positioning plate 5 is attached to one side of the slitting blade 23, the positioning auxiliary plate 63 is attached to the first limiting plate 61. The connecting rod 65 connects the positioning auxiliary plate 63 and the positioning plate 5, ensuring the movement of the positioning auxiliary plate 63 and the positioning plate 5. To maintain synchronization, the distance between the positioning auxiliary plate 63 and the limiting plate 61 is the same as the distance between the positioning plate 5 and the slitting blade 23. Furthermore, with the assistance of the scale 64, the indicated scale of the positioning auxiliary plate 63 represents the distance between the positioning plate 5 and the slitting blade 23. The setup of the auxiliary positioning component 6 provides a foundation for standardizing the operation process. Instead of relying on personal experience to judge the positioning position, operators can adjust it through unified indicator parameters, ensuring consistency in operation among different personnel. This ensures that the width of the light guide plate remains consistent after slitting, thereby improving the quality of the light guide plate after slitting.

[0032] Example 2

[0033] like Figure 5 - Figure 6 As shown, the drive assembly 8 includes a mounting frame 81 fixedly installed on the top of the slitting support base 1. The mounting frame 81 is located at the bottom of the conveyor belt assembly 3, and a transmission screw 83 is rotatably connected inside the mounting frame 81. When adjusting the distance between the positioning plate 5 and the slitting blade 23, the rotary motor 82 is started, causing the rotary motor 82 to drive the transmission screw 83 to rotate inside the mounting frame 81. This allows the drive plate 84 to simultaneously drive the positioning auxiliary plates 63 on both sides to move simultaneously, so that the two sets of positioning auxiliary plates 63 and the connecting rod 65 push the positioning plate 5 and the receiving frame 7 to slide on one side of the slitting assembly 2, thereby adjusting the position of the positioning plate 5.

[0034] To improve the stability of the positioning plate 5 during movement, such as Figure 5 - Figure 6As shown, a rotary motor 82 is fixedly installed on the outer wall of the mounting base frame 81. The output end of the rotary motor 82 passes through the outer wall of the mounting base frame 81 and is fixedly connected to the transmission screw 83. The outer peripheral wall of the transmission screw 83 is threaded with a drive plate 84 that is slidably installed with the mounting base frame 81. The two ends of the drive plate 84 are fixedly connected to the positioning auxiliary plates 63 that are symmetrically arranged on both sides. By setting the positioning auxiliary plates 63 on both sides of the conveyor belt assembly 3 and connecting them to the inner walls of the positioning plate 5 through two sets of connecting rods 65, the stability of the movement of the positioning plate 5 can be ensured.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
