Description

Technical Field

[0001] This utility model relates to the field of light guide element processing technology, specifically to a material suction robotic arm for processing light guide elements. Background Technology

[0002] A light guide element is a device or material that can propagate light in a single beam. It guides the light emitted by a light source to a target area to achieve a more uniform and effective lighting effect. However, when cutting light guide elements, a robotic arm is needed to transfer them. Traditionally, robotic arms would suck the product out of the mold and place it on the cutting table. Then, the robotic arm would wait for the light guide element to be cut, and after the cutting was completed, the robotic arm would clamp and transport the sprue away. Because the robotic arm and the cutting machine have different working time, there will be standby time, which will reduce the overall work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a material-feeding robotic arm for processing light guide elements, so as to solve the problem of reduced work efficiency of robotic arms when in standby mode as mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a material-feeding robotic arm for processing light guide elements, comprising a feeding frame, a single-arm connecting seat fixedly installed on the outer surface of one end of the feeding frame, and the single-arm connecting seat having an L-shaped design, a laser cutting machine fixedly installed on one side of the feeding frame, and a conveyor belt fixedly installed on the side surface of one end of the laser cutting machine, and a placement mechanism provided between the feeding frame and the laser cutting machine, which can reduce the standby time of the robotic arm.

[0005] Preferably, the placement mechanism includes: a material transfer platform, which is fixedly installed on the outer surface of the laser cutting machine, with the laser cutting machine located on one side of the single-arm connecting seat. The material transfer platform is designed to be parallel to the processing work position of the laser cutting machine, and the material transfer platform is designed to be parallel to the conveyor belt.

[0006] By adopting the above technical solution, the light guide element can be removed from the feeding frame and placed on the storage transfer platform, so that the product can be placed on one side of the laser cutting machine, shortening the time from when the robotic arm holds the product to when it reaches the laser cutting machine, and improving the overall work efficiency.

[0007] Preferably, a first sliding rod is fixedly installed on the outer surface of the single-arm connecting seat, and a first electric guide rail is fixedly installed on the outer surface of the first sliding rod. A mobile transfer platform is fixedly installed at the end of the first electric guide rail away from the feeding frame. A platform is provided on the side surface of the first sliding rod, and a tank chain is provided between the platform of the first sliding rod and the mobile transfer platform. A second sliding rod is installed through the outer surface of the mobile transfer platform, and a second electric guide rail is provided between the second sliding rod and the mobile transfer platform. The second sliding rod and the mobile transfer platform are concentrically designed.

[0008] By adopting the above technical solution, the mobile transfer platform can move on the outer surface of the first sliding rod through the first electric guide rail, and the second sliding rod can be moved by the operation of the second electric guide rail, so that the first sliding rod and the second sliding rod can move freely along the XY axis, so that the light guide element can be clamped and moved between the feeding frame, the conveyor belt, the storage transfer platform, and the laser cutting machine, which facilitates the movement of the light guide element.

[0009] Preferably, a mounting bracket is fixedly installed on the outer surface of the end of the second sliding rod near the feeder frame, and a telescopic rod assembly is fixedly installed on the outer surface of the mounting bracket. A connecting plate is rotatably installed on one end of the telescopic rod assembly. A mounting plate is fixedly installed on the outer surface of the connecting plate, and a suction cup assembly is installed through the outer surface of the mounting plate. One end of the suction cup assembly is connected to the suction pipe.

[0010] Using the above technical solution, after the suction cup assembly comes into contact with the light guide element, the gas inside the suction cup assembly can be drawn out through the suction pipe, so that a vacuum can be maintained between the suction cup assembly and the light guide element, allowing the light guide element to be clamped. The extension and retraction of the telescopic rod assembly allows the mounting plate and the suction cup assembly to move in a vertical direction, so that the light guide element can still be accurately placed even under different height differences between the feeding frame, conveyor belt, storage transfer platform and laser cutting machine.

[0011] Preferably, a rotating support mechanism is provided between the telescopic rod assembly and the connecting plate. The rotating support mechanism allows the mounting plate to be flipped, so that people can intuitively see the status of the suction cup assembly at the bottom of the mounting plate, and can easily replace the mounting plate and the suction cup assembly.

[0012] Using the above technical solution, after the robotic arm resets, the mounting plate and suction cup assembly will flip and remain in a vertical state, allowing the operator to directly observe the bottom of the suction cup assembly, check the state of the suction cup assembly's clamping position, and visually see if there is any material stuck, facilitating inspection and maintenance.

[0013] Preferably, the rotating support mechanism includes: a cylinder, which is fixedly installed inside the telescopic rod assembly, and the telescopic rod assembly and the connecting plate are eccentrically designed. The output end of the cylinder is rotatably connected to the connecting plate. Limiting rods are fixedly installed on both sides inside the telescopic rod assembly, and one end of the limiting rod is in contact with the outer surface of the connecting plate.

[0014] By adopting the above technical solution, the eccentric design of the telescopic rod assembly and the connecting plate enables the cylinder to rotate the connecting plate when it is pushed out, which in turn enables the connecting plate to rotate the mounting plate and the suction cup assembly. The limiting rod can provide support after the cylinder retracts and moves the connecting plate back into position, so that the mounting plate and the suction cup assembly can remain horizontal and the suction cup assembly can better clamp the light guide element.

[0015] Preferably, an electrical control box is fixedly installed on the side surface of the single-arm connecting seat, and the electrical control box is connected to the mobile transfer platform. The electrical control box is connected to the telescopic rod assembly, and an alarm light is fixedly installed on the outer surface of the mobile transfer platform.

[0016] By adopting the above technical solution, the connection between the mobile transfer platform and the telescopic pole assembly can be made through the electrical control box, making it more convenient to inspect the circuit, and the fault alarm of the robotic arm can be realized through the alarm light.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the material suction robotic arm for processing light guide elements:

[0018] 1. When processing the light guide element, the mounting plate will first flip up, and the extension of the telescopic rod assembly will drive the suction cup assembly to descend, clamp the material and place it inside the laser cutting machine for cutting. At the same time, another material can be placed inside the storage transfer platform. When the laser cutting machine finishes processing and is loading, the robotic arm can immediately clamp the material in the storage transfer platform and place it inside the laser cutting machine. The material can be transported during the cutting time, shortening the material clamping and transportation time.

[0019] 2. After the laser cutting machine finishes cutting the material, the remaining sprue can be clamped by the suction cup assembly and placed into the conveyor belt for transportation. Then, the material in the material transfer platform can be clamped by the suction cup assembly on the robotic arm and immediately placed into the laser cutting machine for processing. This reduces the waiting time for the laser cutting machine to be loaded, enabling the laser cutting machine to work continuously and improving the overall processing efficiency.

[0020] 3. The telescopic rod assembly, mounting plate, and suction cup assembly can clamp materials and move them between the feeding frame, conveyor belt, material transfer platform, and laser cutting machine. The telescopic movement of the telescopic rod assembly can reduce or eliminate height differences between the feeding frame, conveyor belt, material transfer platform, and laser cutting machine. After the robotic arm resets, the cylinder will extend and move the connecting plate. The rotation of the connecting plate will cause the mounting plate and suction cup assembly to flip, allowing the suction cup assembly to be exposed for easy observation. When replacement is needed, the mounting plate can be easily removed from the connecting plate. When working, the cylinder will retract and move the connecting plate back to its original position. The limit rod limits the connecting plate, keeping the mounting plate and suction cup assembly horizontal. This allows the suction cup assembly to better fit the material, improving the stability of material clamping and facilitating the inspection and replacement of the mounting plate and suction cup assembly.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a material suction robotic arm for processing light guide elements, including a feeding frame 1, a single arm connecting seat 2 fixedly installed on the outer surface of one end of the feeding frame 1, and the single arm connecting seat 2 is L-shaped, a laser cutter 19 is fixedly installed on one side of the feeding frame 1, and a conveyor belt 17 is fixedly installed on the side surface of one end of the laser cutter 19, and a placement mechanism is provided between the feeding frame 1 and the laser cutter 19, which can reduce the standby time of the robotic arm.

[0030] The L-shaped design of the single-arm connecting seat 2 can extend the moving distance of the mobile transfer platform 5, making it convenient to transport and transfer materials.

[0031] The placement mechanism includes a material transfer platform 18, which is fixedly installed on the outer surface of the laser cutting machine 19, and the laser cutting machine 19 is located on one side of the single-arm connecting seat 2. The material transfer platform 18 and the processing work position of the laser cutting machine 19 are designed to be parallel, and the material transfer platform 18 and the conveyor belt 17 are designed to be parallel.

[0032] The light guide element is held by the suction cup assembly 16, and then the robotic arm places the light guide element above the storage transfer platform 18, so that the product is placed on one side of the laser cutting machine 19. After the cutting is completed, there is no need to take the material from inside the feeding frame 1. The cut sprue is simply clamped and placed on the conveyor belt 17. Then the scaled material on the storage transfer platform 18 can be clamped and placed into the laser cutting machine 19. This shortens the material retrieval time and distance, and the material can be clamped and placed on the storage transfer platform 18 for later use while the laser cutting machine 19 is working. This also shortens the time it takes for the robotic arm to clamp the product and put it into the laser cutting machine 19 after subsequent processing, thus improving the overall efficiency of the cutting process.

[0033] A first sliding rod 3 is fixedly installed on the outer surface of the single-arm connecting seat 2, and a first electric guide rail 4 is fixedly installed on the outer surface of the first sliding rod 3. A mobile transfer platform 5 is fixedly installed at the end of the first electric guide rail 4 away from the feeding frame 1. A platform is provided on the side surface of the first sliding rod 3, and a tank chain is provided between the platform of the first sliding rod 3 and the mobile transfer platform 5. A second sliding rod 6 is installed through the outer surface of the mobile transfer platform 5, and a second electric guide rail 7 is provided between the second sliding rod 6 and the mobile transfer platform 5. The second sliding rod 6 and the mobile transfer platform 5 are concentrically designed.

[0034] The first electric guide rail 4 allows the mobile transfer platform 5 to move above the first sliding rod 3, facilitating the suction of material from the feeding frame 1 and its movement above the storage transfer platform 18. The material is then placed inside the storage transfer platform 18. After the laser cutting machine 19 completes its cutting process, the first electric guide rail 4 moves the telescopic rod assembly 11 above the laser cutting machine 19. Activation of the telescopic rod assembly 11 causes the suction cup assembly 16 to enter the laser cutting machine 19 and suction up the remaining sprue material. The upward movement of the telescopic rod assembly 11 lifts the sprue material, and the second electric guide rail 7 drives the second sliding rod 6 to move the sprue material held by the suction cup assembly 16 to the conveyor belt. Above 17, by venting the suction cup assembly 16, the sprue material falls onto the conveyor belt 17 to complete the unloading. Then, by moving the first electric guide rail 4 and the second electric guide rail 7, the first sliding rod 3 and the second sliding rod 6 can be moved, so that the material placed in the storage transfer platform 18 can be clamped and put into the laser cutting machine 19. After the cutting is completed, the material can be put into the laser cutting machine 19 for another operation. It can also easily move the telescopic rod assembly 11 to the feeding frame 1, the conveyor belt 17, the storage transfer platform 18, and the laser cutting machine 19, reducing the waiting time for the laser cutting machine 19 to be loaded, so that the laser cutting machine 19 can perform cutting operations at any time.

[0035] A mounting bracket 10 is fixedly installed on the outer surface of the second sliding rod 6 near the feeder frame 1, and a telescopic rod assembly 11 is fixedly installed on the outer surface of the mounting bracket 10. A connecting plate 13 is rotatably installed on one end of the telescopic rod assembly 11, and a mounting plate 15 is fixedly installed on the outer surface of the connecting plate 13. A suction cup assembly 16 is installed through the outer surface of the mounting plate 15, and one end of the suction cup assembly 16 is connected to the suction pipe.

[0036] The telescopic rod assembly 11 can be easily installed and fixed by the mounting bracket 10. The telescopic rod assembly 11 can easily lift the mounting plate 15 and the suction cup assembly 16, making it convenient to pick up and put down materials in the feeding frame 1, the conveyor belt 17, the material transfer platform 18, and the laser cutting machine 19. It can still hold and place materials even when there is a height difference between the feeding frame 1, the conveyor belt 17, the material transfer platform 18, and the laser cutting machine 19.

[0037] A rotating support mechanism is provided between the telescopic rod assembly 11 and the connecting plate 13. The mounting plate 15 can be flipped by rotating the support mechanism, so that people can see the status of the suction cup assembly 16 at the bottom of the mounting plate 15 and can easily replace the mounting plate 15 and the suction cup assembly 16.

[0038] After the first sliding rod 3, the second sliding rod 6 and the telescopic rod assembly 11 automatically return to their original positions, the cylinder 12 will push out and push the connecting plate 13, so that the connecting plate 13 can drive the mounting plate 15 and the suction cup assembly 16 to flip over, allowing the mounting plate 15 and the suction cup assembly 16 to be exposed on the bottom surface. This makes it convenient for operators to observe the clamping part of the suction cup assembly 16 to determine whether it needs to be replaced and maintained. It also makes it easy to remove the mounting plate 15 from the connecting plate 13 to facilitate the replacement of the suction cup assembly 16.

[0039] The rotating support mechanism includes a cylinder 12, which is fixedly installed inside the telescopic rod assembly 11. The telescopic rod assembly 11 and the connecting plate 13 are eccentrically designed. The output end of the cylinder 12 is rotatably connected to the connecting plate 13. Limiting rods 14 are fixedly installed on both sides inside the telescopic rod assembly 11, and one end of the limiting rod 14 is in contact with the outer surface of the connecting plate 13.

[0040] As the robotic arm's automatic return cylinder 12 extends, the eccentric design of the telescopic rod assembly 11 and the connecting plate 13 allows the connecting plate 13 to be pushed and flipped. When working, the cylinder 12 retracts, causing the connecting plate 13 to return to its original position, making the connecting plate 13 contact the limiting rod 14. The limiting rod 14 limits the position, ensuring that the mounting plate 15 and the suction cup assembly 16 remain horizontal at all times, allowing the suction cup assembly 16 to better adhere to the material and clamp more securely.

[0041] An electrical control box 8 is fixedly installed on the side surface of the single-arm connecting seat 2, and the electrical control box 8 is connected to the mobile transfer platform 5. The electrical control box 8 is also connected to the telescopic rod assembly 11. An alarm light 9 is fixedly installed on the outer surface of the mobile transfer platform 5.

[0042] The control circuits of the mobile transfer platform 5 and the telescopic rod assembly 11 can be centralized in the electrical control box 8, which facilitates the inspection and maintenance of the circuits. The alarm light 9 can be used to visually check whether the robotic arm has malfunctioned and trigger an alarm.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
