[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] First embodiment:

[0024] Please refer to the following: Figure 1 and Figure 2 The present invention provides an automatic cutting device for acrylic optical guides, comprising: a fixture device 1, an adjustment device 2, and a clamping device 3;

[0025] The adjustment device 2 includes two adjustment rods 21, multiple adjustment sleeves 22, two drive devices 23, multiple adjustment frames 24, and multiple fixing devices 25.

The drive devices 23 are used to drive the adjustment frames 24 to move. The multiple fixing devices 25 are respectively set inside the multiple adjustment sleeves 22.

[0026] The clamping device 3 is located on the top of the adjusting frame 24 and is used to position and clamp the acrylic light guide.

[0027] The driving device 23 consists of multiple linear sliding modules. The two ends of the multiple linear sliding modules are respectively fixedly connected to the top of multiple adjusting sleeves 22, while the bottom of multiple adjusting frames 24 are respectively fixedly installed on the output end of the multiple linear sliding modules, which are used to drive the adjusting frames 24 to move through the linear sliding modules.

[0028] The clamping device 3 includes a support frame, a driving component, and two clamping plates. One end of the support frame is fixedly installed on the top of the adjusting frame 24, the driving component is fixedly installed inside the support frame, the clamping plate is fixedly installed at the output end of the driving component, and the other clamping plate is fixedly installed on the top of the support frame. The driving component drives the clamping plate to move and cooperate with the other clamping plate, thereby clamping and limiting the acrylic light guide.

[0029] The driving components are hydraulic rods, cylinders, and linear sliding modules.

[0030] The drive device 23 includes a movable frame 231, two movable blocks 232, a rotating rod 233 and a servo motor 234. The two movable blocks 232 are slidably connected to the inside of the movable frame 231, the rotating rod 233 is rotatably connected to the inside of the movable frame 231, and the servo motor 234 is fixedly installed at one end of the movable frame 231, and its output end is connected to one end of the rotating rod 233 through a coupling.

[0031] The bottom ends of the movable frame 231 are fixedly connected to the top of the two adjusting sleeves 22 respectively. The movable frame 231 has a rectangular groove inside. The movable block 232 is a rectangular block that matches the rectangular groove and is slidably connected inside the rectangular groove. The rotating rod 233 is a threaded rod with opposing threads. The two movable blocks 232 have threaded holes that match the rotating rod 233 inside. The bottom of the adjusting frame 24 is fixedly installed on the top of the movable block 232. After the servo motor 234 is started, it drives the rotating rod 233 to rotate to one side, so that the two movable blocks 232 move towards the middle on the surface of the rotating rod 233, thereby driving the movable frame adjusting frame 24 to move and adjust the position of the clamping device 3.

[0032] In the other set of moving frames 231 of the two sets of drive devices 23, the rotating rod 233 inside is a threaded rod, and a moving block 232 is threadedly connected to its surface.

[0033] The fixing device 25 includes a fixing hole 251 and a fixing pin 252. The fixing hole 251 is opened inside the adjusting rod 21, and the fixing pin 252 is slidably connected inside the fixing hole 251.

[0034] The adjusting sleeve 22 also has a fixing hole 251 inside, which is used to limit the adjusting sleeve 22 after it has moved to a suitable position on the surface of the adjusting rod 21 by inserting the fixing pin 252 into the fixing hole 251.

[0035] The working principle of this first embodiment is as follows:

[0036] When in use, if it is necessary to adjust the left and right position of the clamping device 3, the fixing device 25 is removed, and the driving device 23 is moved to one side, which drives the two adjusting sleeves 22 to move to one side on the surface of the two adjusting rods 21 respectively. This drives the two adjusting frames 24 connected to the clamping device 3 to move to the appropriate position, and then the fixing device 25 is installed.

[0037] When it is necessary to move the clamping device 3 back and forth, the drive device 23 is activated to move the adjusting frame 24 to the appropriate position.

[0038] In this first embodiment, the position of the clamping device 3 can be adjusted in the front-back and left-right directions by means of the adjusting rod 21, the adjusting sleeve 22, the driving device 23, the adjusting frame 24, and the fixing device 25, so as to facilitate the adjustment of the clamping device 3 to a suitable position according to the size of the light guide injection molding.

[0039] Second embodiment:

[0040] Please refer to the following: Figure 3 and Figure 4 Based on the first embodiment of this application which provides an automatic acrylic light guide cutting device, the second embodiment of this application proposes another automatic acrylic light guide cutting device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0041] Specifically, the difference in the acrylic light guide automatic cutting device provided in the second embodiment of this application is that cleaning brushes 4 are fixedly installed on both sides of the moving block 232, and cleaning plates 5 are fixedly connected to the bottom of the two cleaning brushes 4.

[0042] A circular ring is fixedly installed on the surface of the cleaning brush 4. One side of the circular ring is fixedly installed on one side of the moving block 232. The cleaning brush 4 is in contact with the surface of the rotating rod 233 and is used to clean the rotating rod 233.

[0043] The top of the cleaning plate 5 is fixedly connected to the bottom of the circular ring.

[0044] The movable frame 231 has a discharge trough 6 inside, and a collection box 7 is fixedly connected to one side of the movable frame 231. The bottom of the discharge trough 6 is sloped to discharge debris inside the movable frame 231 into the collection box 7. The collection box 7 is used to collect and store debris.

[0045] The collection box 7 has a limiting component 8 inside, which includes a limiting groove 81 and a limiting block 82. The limiting groove 81 is formed in the collection box 7, and the limiting block 82 is slidably connected inside the limiting groove 81. A baffle 9 is fixedly connected to one side of the limiting block 82. The baffle 9 is used to seal one end of the collection box 7, thereby facilitating the removal of debris from inside the collection box 7.

[0046] The working principle of this second embodiment is as follows:

[0047] In use, when the moving block 232 moves, it drives the cleaning brush 4 connected to the cleaning plate 5 to move, thereby cleaning the debris that has entered the moving frame 231. At the same time, when the threaded rod 33 rotates to one side, the cleaning brush 4 cleans the surface of the threaded rod 33.

[0048] The debris scraped off by the cleaning plate 5 is discharged into the collection box 7 through the discharge chute 6 for storage.

[0049] When it is necessary to clean the collection box 7, the baffle 9 can be removed by pulling the baffle 9 upward, causing the limiting block 82 to move upward and separate inside the limiting groove 81. Then, the debris inside the collection box 7 can be swept away.

[0050] After cleaning is completed, insert the limiting block 82 into the limiting groove 81 and move it to the appropriate position before installing the baffle 9.

[0051] In this second embodiment, the cleaning brush 4, together with the cleaning plate 5, the discharge trough 6 and the collection box 7, cleans the inside of the movable frame 231, thereby preventing dust and debris from adhering to the surface of the rotating rod 233 and affecting its use.

[0052] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
