Description
Technical Field
[0001] This utility model relates to the field of shearing machine technology, specifically a plastic lens shearing machine. Background Technology
[0002] In the eyewear manufacturing industry, plastic lenses have become the mainstream lens material due to their advantages such as light weight and high impact resistance. As a key piece of equipment in the lens production process, the performance of plastic lens cutting machines directly affects the production efficiency and quality of lenses. With the continuous growth of market demand for eyewear products and the increasing demands of consumers for lens quality, higher standards are being set for the automation level, processing precision, and work efficiency of plastic lens cutting machines.
[0003] Traditional plastic lens cutting machines often use a blowing method for waste removal, using airflow to blow waste off the worktable. However, blowing causes waste to spread everywhere, making it difficult to collect. This not only increases the difficulty of waste recycling but can also lead to a dirty and messy production environment. Furthermore, due to the large area of the worktable, manual blowing cannot cover the entire surface, easily resulting in omissions. Residual waste on the processing table can interfere with subsequent lens processing, reducing product quality. Therefore, a new plastic lens cutting machine is needed to solve the problems existing in the current technology. Utility Model Content
[0004] The purpose of this invention is to provide a plastic lens cutting machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic lens cutting machine, comprising: The shearing machine body is used for cutting and processing plastic lenses; A flipping and feeding mechanism is built into the upper port of the shearing machine body. The flipping and feeding mechanism is used to lift and place plastic lenses. A negative pressure suction mechanism is installed inside the equipment chamber of the shearing machine body. The negative pressure suction mechanism is used for negative pressure adsorption and positioning of plastic lenses.
[0006] Preferably, the flipping and discharging mechanism includes a first rotating plate and a second rotating plate, and two fixed columns are fixed on the inner wall of the equipment chamber of the shearing machine body. The first rotating plate is rotatably connected to one fixed column, and the second rotating plate is rotatably connected to the other fixed column.
[0007] Preferably, a support mechanism is provided below the first and second rotating plates, and the support mechanism is used to switch between different height positions to support the first and second rotating plates. Preferably, the negative pressure suction mechanism includes a positioning suction cup, the upper end face of which is provided with a negative pressure suction port, a vacuum pump is fixed on the bottom wall of the equipment chamber of the shearing machine body, and a connecting branch pipe is fixed between the positioning suction cup and the vacuum pump.
[0008] Preferably, the support mechanism includes a triangular prism, which is disposed directly below the first rotating plate and the second rotating plate.
[0009] Preferably, a rotating shaft is fixed at the center of each end face of the triangular prism, and bearing sleeves are fixed on both sides of the equipment chamber of the shearing machine body, with the two ends of the rotating shaft passing through the bearing sleeves respectively.
[0010] Preferably, a drive motor is fixed inside the shearing machine body, and the output shaft of the drive motor is fixed at one end of the rotating shaft.
[0011] This utility model provides a plastic lens cutting machine, which has the following advantages compared with the prior art: With the set flipping and supporting mechanism, the triangular prism can switch to different height positions to support the first and second rotating plates by rotating. When the first and second rotating plates flip downwards when the triangular prism lowers its support height, the waste material from the lens cutting process can slide down into the equipment room through the ramp formed by the first and second rotating plates to achieve automatic waste collection. This improves the situation where waste is spread and difficult to collect due to the traditional spray cleaning method of cleaning the workbench.
[0012] With the support mechanism in place, the first and second rotating plates change cyclically from a horizontal state to a downward tilting angle when the triangular prism rotates. The vibration generated by the collision between the first and second rotating plates and the triangular prism during the downward tilting process promotes the sliding of waste materials along the slope, thereby preventing waste materials from remaining on the surfaces of the first and second rotating plates. This ensures the cleaning effect of the surfaces on which the first and second rotating plates are placed, and improves the situation where the cleaning is not thorough due to the large workbench area and the omissions caused by manual blowing when using traditional spray cleaning methods.

[0015] 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.
[0016] Please see Figure 1-4 This utility model provides a plastic lens cutting machine, comprising: The shearing machine body 1 is used for cutting plastic lenses. The shearing machine body 1 has a built-in high-precision CNC system. Through the preset lens cutting program, it accurately controls the movement trajectory of the cutting tool. During the cutting process, at the moment the tool contacts the lens, it separates the plastic lens according to the predetermined shape by relying on the powerful cutting force. The flipping and feeding mechanism 2 is built into the upper port of the shearing machine body 1. The flipping and feeding mechanism 2 is used to lift and place plastic lenses. In the lens production workshop of an eyewear manufacturing company, the worker places the plastic lens to be processed on the upper port of the shearing machine body 1. At this time, the lens is in contact with the positioning suction cup 11 and the first rotating plate 3 and the second rotating plate 4 in a horizontal state, providing a stable lifting surface for the lens. The negative pressure suction mechanism 5 is located inside the equipment chamber of the shearing machine body 1. The negative pressure suction mechanism 5 is used for negative pressure adsorption and positioning of plastic lenses. When the negative pressure suction mechanism 5 inside the equipment chamber of the shearing machine body 1 is activated, the negative pressure adsorption port 15 of the positioning suction cup 11 forms a negative pressure passage with the vacuum pump 14 through the connecting branch pipe 13, generating suction to firmly adsorb and fix the plastic lens, ensuring the stability of the lens position during the cutting process.
[0017] It is worth noting that the flipping and discharging mechanism 2 includes a first rotating plate 3 and a second rotating plate 4. Two fixed columns 12 are fixed on the inner wall of the equipment chamber of the shearing machine body 1. The first rotating plate 3 is rotatably connected to one fixed column 12, and the second rotating plate 4 is rotatably connected to the other fixed column 12. A support mechanism 6 is provided below the first rotating plate 3 and the second rotating plate 4. The support mechanism 6 is used to switch between different height positions to support the first rotating plate 3 and the second rotating plate 4. After the cutting is completed, the drive motor 10 drives the triangular prism 7 in the support mechanism 6 to rotate. The triangular prism 7 rotates in the bearing sleeve 9 through the rotating shaft 8, switching between different height positions to support the first rotating plate 3 and the second rotating plate 4. When the triangular prism 7 lowers the support height, the first rotating plate 3 and the second rotating plate 4 flip downward to form an inclined ramp, so that the cutting waste slides down the ramp into the equipment chamber, completing automatic collection and avoiding the spread of waste.
[0018] It is worth noting that the negative pressure suction mechanism 5 includes a positioning suction cup 11, with a negative pressure suction port 15 on its upper surface. A vacuum pump 14 is fixed on the bottom wall of the equipment chamber of the shearing machine body 1, and a connecting branch pipe 13 is fixed between the positioning suction cup 11 and the vacuum pump 14. Throughout the cleaning process, the negative pressure suction port 15 of the positioning suction cup 11 maintains negative pressure suction and positioning on the finished lens. After the small-volume finished lens is cleaned by blowing, the finished lens is removed.
[0019] It is worth noting that the support mechanism 6 includes a triangular prism 7, which is located directly below the first rotating plate 3 and the second rotating plate 4. A rotating shaft 8 is fixed at the center of each end face of the triangular prism 7. Bearing sleeves 9 are fixed on both sides of the equipment chamber of the shearing machine body 1. The two ends of the rotating shaft 8 pass through the bearing sleeves 9 respectively. A drive motor 10 is fixed inside the shearing machine body 1. The output shaft of the drive motor 10 is fixed at one end of the rotating shaft 8. The triangular prism 7 rotates continuously, and the first rotating plate 3 and the second rotating plate 4 change cyclically between horizontal and downward tilting states. During the downward tilting process, the first rotating plate 3 and the second rotating plate 4 collide with the triangular prism 7 to generate vibration force, which causes the waste material remaining on the surface of the first rotating plate 3 and the second rotating plate 4 to slide off more quickly, ensuring that the placement surface is clean.
[0020] This solution has the following working process: In the lens production workshop of an eyewear manufacturing company, the efficient cutting of plastic lenses is a key link to ensure production capacity and quality. In actual production, workers place the plastic lenses to be processed on the positioning suction cup 11 and the flipping and discharging mechanism 2 at the upper port of the shearing machine body 1. The flipping and discharging mechanism 2 consists of a first rotating plate 3 and a second rotating plate 4. When the first rotating plate 3 and the second rotating plate 4 are kept in a horizontal state, they can stably support the lenses and provide a stable initial state for subsequent processing. When positioning the plastic lens, the negative pressure suction mechanism 5, which is located inside the equipment room of the shearing machine body 1, starts to work. The positioning suction cup 11 forms a negative pressure passage with the vacuum pump 14 through the negative pressure suction port 15 and the connecting branch pipe 13, firmly adsorbing and positioning the plastic lens. After the cutting is completed, the triangular prism 7 in the support mechanism 6 rotates in the bearing sleeve 9 through the rotating shaft 8 under the drive of the drive motor 10, switching between different height positions to support the first rotating plate 3 and the second rotating plate 4. Since the three edges of the triangular prism 7 provide maximum support to the first rotating plate 3 and the second rotating plate 4, the three sides of the triangular prism 7 will support the first rotating plate 3 and the second rotating plate 4 at their lowest height positions. This allows the first rotating plate 3 and the second rotating plate 4 to flip downwards when the triangular prism 7 lowers its support height. This allows the waste material from the lens cutting process to slide down into the equipment room via the ramp formed by the first rotating plate 3 and the second rotating plate 4, achieving automatic waste collection. This improves the situation where waste is spread and difficult to collect due to the traditional spray cleaning method of cleaning the workbench. When the triangular prism 7 rotates, the first rotating plate 3 and the second rotating plate 4 change cyclically from a horizontal state to a downward tilting angle. The vibration generated by the collision between the first rotating plate 3 and the second rotating plate 4 and the triangular prism 7 during the downward tilting process will promote the waste to slide down the slope, thereby preventing the waste from remaining on the surface of the first rotating plate 3 and the second rotating plate 4. This ensures the cleaning effect of the surface on which the first rotating plate 3 and the second rotating plate 4 are placed, and improves the situation where the cleaning is not thorough due to the large workbench area and the omissions caused by manual blowing when cleaning by traditional spraying method. Throughout the cleaning process, the negative pressure suction port 15 of the positioning suction cup 11 always performs negative pressure suction and positioning on the finished lens. The finished lens with small volume is cleaned by blowing and then removed. The shearing machine body 1 has a built-in high-precision CNC system. Through the preset lens cutting program, it accurately controls the movement trajectory of the cutting blade. During the cutting process, at the moment the blade contacts the lens, it uses powerful cutting force to separate the plastic lens according to the predetermined shape.
