Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive headlight lens technology, and in particular to a tooling for cutting off excess material from automotive headlight lenses. Background Technology
[0002] Automotive headlight lenses are generally produced through injection molding. During the injection molding process, various molds with different structures are designed according to the shape of the lens product. Each mold has a different gate location and injection method. However, after the product is formed, residual material will be formed at the gate, which is integrated with the lens. After the lens is removed, the residual material needs to be removed to obtain a qualified product.
[0003] The current method for removing excess material from optical lenses typically involves manual removal using a utility knife. This method inevitably has the following drawbacks: First, the optical lenses are still very hot when removed from the mold, and manually cutting off the excess material requires forcefully squeezing the lens, which may result in burns to the operator. Second, the optical lens material is quite hard, requiring considerable force to cut the excess material; improper operation may cut the operator's hands or even damage the product. Furthermore, the removal of excess material is labor-intensive, tedious, and physically demanding. Additionally, when operators cut the excess material at room temperature, the shear stress concentrates, making the lens material more resilient, resulting in even more time-consuming and labor-intensive processes. Utility Model Content
[0004] The purpose of this utility model is to provide a tooling for cutting off excess material from automotive headlight lenses. This tooling can achieve hot cutting by cutting off excess material at high temperatures, avoiding the time-consuming and labor-intensive process of cold cutting, and also avoiding manual operation, thus saving time and effort.
[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a tooling for cutting off excess material from a vehicle headlight lens, including a base connected to a bracket. The top of the bracket is connected to a downward-facing upper cutter. A cylinder is fixedly mounted on the base, and the movable end of the cylinder is connected to a connecting plate. The connecting plate is connected to a heat insulation plate, which is connected to a fixing component. The fixing component is connected to a heat-conducting sleeve to achieve the connection between the heat insulation plate and the heat-conducting sleeve. The heat-conducting sleeve is connected to a support plate, which has a receiving groove containing a heating element. The heating element is connected to an external power source. The support plate is connected to a lower cutter. The lower cutter, the support plate, and the heat-conducting sleeve are all thermally conductive. The lower cutter corresponds to the upper cutter, and both the upper and lower cutters are arc-shaped and adapted to the edge of the excess material from the lens. The cylinder is connected to a control device.
[0006] Preferably, the fixing assembly includes a first fixing plate and a second fixing plate connected to each other, and the first fixing plate and the second fixing plate have high temperature resistance.
[0007] Preferably, the first fixing plate has first fixing plate mounting holes at its four corners, the heat insulation plate has heat insulation plate mounting holes at its four corners, and the connecting plate has connecting plate mounting holes at its four corners. The first fixing plate mounting holes, the heat insulation plate mounting holes, and the connecting plate mounting holes correspond to each other and are connected by bolts.
[0008] Preferably, the second fixing plate is provided with a second fixing plate mounting hole, the heat-conducting sleeve is provided with a heat-conducting sleeve mounting hole, and the first fixing plate is also provided with a first fixing plate connecting hole. The heat-conducting sleeve mounting hole, the second fixing plate mounting hole, and the first fixing plate connecting hole correspond to each other and are connected by bolts.
[0009] Preferably, the heat-conducting sleeve includes a cylindrical portion and a plate portion connected to each other, and the heat-conducting sleeve mounting hole is provided on the plate portion.
[0010] Preferably, the cylindrical part is provided with a cylindrical part mounting hole, the support plate is provided with a support plate mounting hole, and the lower cutter is provided with a lower cutter mounting hole. The lower cutter mounting hole, the support plate mounting hole, and the cylindrical part mounting hole correspond to each other and are connected by bolts.
[0011] Preferably, the lower cutter includes a lower cutter portion and a lower cutter holder, and the lower cutter mounting hole is provided on the lower cutter holder.
[0012] Preferably, the receiving groove is located on the top surface of the support plate, and the lower surface of the lower knife holder abuts against the heating element.
[0013] Preferably, the upper cutter includes an upper blade part and an upper blade holder, and the bracket includes a horizontal bar and a vertical bar connected to each other, the vertical bar being connected to the base and the horizontal bar being connected to the upper blade holder.
[0014] The present invention achieves the following beneficial technical effects compared to the prior art: This utility model provides a tooling for cutting excess material from automotive headlight lenses. A connecting plate, heat insulation plate, first fixing plate, second fixing plate, heat-conducting sleeve, support plate, and lower cutter are integrally connected and fixed to the movable end of a cylinder. When the cylinder is activated by a control device, causing its movable end to move upward, it moves the connecting plate, heat insulation plate, first fixing plate, second fixing plate, heat-conducting sleeve, support plate, and lower cutter upward together. This tooling is operated by a robotic gripper. When the robotic gripper removes the injection-molded lens and places it against the upper cutter, the cylinder is activated. The upward movement of the cylinder's movable end drives the lower cutter upward, aligning it with the edge of the excess material for cutting. This eliminates manual operation, saving time and effort. Furthermore, the lower cutter, support plate, and heat-conducting sleeve are all thermally conductive. During excess material cutting, an external power source can activate a heating element, which transfers heat to the lower cutter for thermal cutting of the excess material. In addition, the heat generated by the heating element is also transferred to the heat-conducting sleeve, which stores the heat to keep the lower cutting blade at a high temperature for hot cutting, thus avoiding the time-consuming and labor-intensive cold cutting. Furthermore, both the first and second fixing plates are made of high-temperature resistant materials, ensuring the reliability of the device. By setting up a heat insulation plate, the heat transferred by the heat-conducting sleeve is isolated, preventing heat from being transferred to the cylinder and protecting the cylinder.

Detailed Implementation
[0016] This utility model provides a tooling for cutting off excess material from automotive headlight lenses, such as... Figures 1-2As shown, the fixture includes a base 1, which is connected to a support 2, thus supporting the tooling. Specifically, the support 2 includes a horizontal bar 3 and a vertical bar 4 connected to each other. The vertical bar 4 is connected to the base 1, and the horizontal bar 3 is connected to the upper cutter 5, which is positioned downwards. A cylinder 6 is fixedly connected to the base 1. The cylinder 6 is connected to a control device, and the movable end of the cylinder 6 is connected to a connecting plate 7. The connecting plate 7 is connected to a heat insulation plate 8, and the heat insulation plate 8 is connected to a fixing assembly. Specifically, the fixing assembly includes a first fixing plate 9 and a second fixing plate 10 connected to each other. The first fixing plate 9 and the second fixing plate 10 are heat-resistant. The heat insulation plate 8 is connected to the first fixing plate 9. The second fixing plate 10 is connected to the heat-conducting sleeve 11. The heat-conducting sleeve 11 is connected to a support plate 12. The top surface of the support plate 12 is provided with a receiving groove 13. The receiving groove 13 contains a heating element (not shown). The heating element is connected to an external power supply. The support plate 12 is connected to the lower cutter 14. The lower cutter 14 corresponds to the upper cutter 5. Both the upper cutter 5 and the lower cutter 14 are arc-shaped and adapted to the edge of the optical lens scrap 16 of the optical lens 15.
[0017] In this embodiment, the connecting plate 7, heat insulation plate 8, first fixing plate 9, second fixing plate 10, heat-conducting sleeve 11, support plate 12, and lower cutter 14 are fixedly connected as a whole and are fixed to the movable end of the cylinder 6. When the cylinder 6 is activated by the control device, causing the movable end of the cylinder 6 to move upward, it will drive the connecting plate 7, heat insulation plate 8, first fixing plate 9, second fixing plate 10, heat-conducting sleeve 11, support plate 12, and lower cutter 14 to move upward together. This fixture is operated by a robotic arm gripper. When the robotic arm gripper takes out the injection-molded lens 15 and abuts it against the upper cutter 5, the cylinder 6 is activated. The upward movement of the movable end of the cylinder 6 will drive the lower cutter 14 to move upward, thereby aligning the lower cutter 14 with the cutting edge of the lens scrap 16 to cut off the lens scrap 16, avoiding manual operation and achieving time and labor saving. In addition, the lower cutter 14, support plate 12, and heat-conducting sleeve 11 are all thermally conductive. When cutting off the excess material 16 of the optical lens, the heating element can be activated by an external power source. The heat generated by the heating element is transferred to the lower cutter 14 to achieve hot cutting of the excess material 16. The heat generated by the heating element is also transferred to the heat-conducting sleeve 11, which stores the heat to keep the lower cutter 14 at a high temperature, thus avoiding the time-consuming and laborious process of cold cutting. Furthermore, the first fixing plate 9 and the second fixing plate 10 are both made of high-temperature resistant material, ensuring the reliability of the device. By setting the heat insulation plate 8, the heat transferred to the heat-conducting sleeve 11 is isolated, preventing heat from being transferred to the cylinder 6 and protecting the cylinder 6.
[0018] The upper cutter 5 includes an upper cutter part 17 and an upper cutter seat 18 connected to each other. The crossbar 3 is connected to the upper cutter seat 18. The lower cutter 14 includes a lower cutter part 19 and a lower cutter seat 20. The upper cutter part 17 and the lower cutter part 19 correspond to each other and are both arc-shaped, so as to remove the excess material 16 of the optical lens.
[0019] The first fixing plate 9 has mounting holes 21 at its four corners, the heat insulation plate 8 has mounting holes 22 at its four corners, and the connecting plate 7 has mounting holes 23 at its four corners. The mounting holes 21, 22, and 23 correspond to each other and are connected by bolts, thus connecting the first fixing plate 9, the heat insulation plate 8, and the connecting plate 7. The heat-conducting sleeve includes a cylindrical part 24 and a plate part 25 connected to each other. The plate part 25 has mounting holes 26. The second fixing plate 10 has mounting holes 27. The first fixing plate 9 also has connecting holes 28. The mounting holes 26, 27, and 28 correspond to each other and are connected by bolts, thus connecting the first fixing plate 9, the second fixing plate 10, and the heat-conducting sleeve 11. The lower cutter holder 20 has a lower cutter mounting hole 29, the cylindrical part 24 has a cylindrical part mounting hole 30, and the support plate 12 has a support plate mounting hole 31. The lower cutter mounting hole 29, the support plate mounting hole 31, and the cylindrical part mounting hole 30 correspond to each other and are connected by bolts, realizing the connection between the lower cutter 14, the support plate 12, and the heat-conducting sleeve 11. The receiving groove 13 is provided on the top surface of the support plate 12, and the lower surface of the lower cutter holder 20 abuts against the heating element, so that the heat generated by the heating element can be directly transferred to the lower cutter 14, ensuring heat transfer.
[0020] The fixture for removing excess material from a vehicle headlight lens provided by this utility model first activates an external power supply to heat the heating element; then, a robotic arm picks up the lens 15 and places it above the fixture, with the upper blade 17 resting against the edge of the excess material 16; the control device moves the movable end of the cylinder 6 upward, causing the lower cutter 14 to move upward, with the lower blade 19 aligned with the upper blade 17, thus removing the excess material 16; the control device then moves the movable end of the cylinder 6 downward, causing the lower cutter 14 to move downward, and the robotic arm removes the removed lens 15, thus achieving the removal of excess material from the lens.
[0021] It should be noted that the robotic gripper is existing technology and will not be described in detail here.
[0022] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
