Description

Technical Field

[0001] This application relates to the field of optical appliance manufacturing, and particularly to a large optical coating umbrella forming device. Background Art

[0002] An optical lens is a lens obtained by cold working (including cutting, milling, polishing, etc.) a glass sheet to reach the required size and surface shape. In order to increase the light transmittance of the lens or increase the reflectivity of the lens to some wavelengths, it is necessary to perform a coating treatment on the optical lens, that is, to coat a layer of film on the lens after cold working treatment.

[0003] The coating treatment of the optical lens requires the use of a coating machine and a coating umbrella. The coating umbrella is used to carry the optical lens to be coated. A positioning hole is opened at the top of the coating umbrella, and a plurality of mounting holes for placing the optical lens are opened on the overall umbrella surface; the coating machine is installed in the coating chamber, and is provided with coating materials and a driving member for driving the coating umbrella to rotate.

[0004] When coating the optical lens, it is necessary to connect the coating umbrella with the driving member through the positioning hole, place the lens to be coated in the mounting hole, and then evaporate or sublimate the coating material through the coating machine and splash it onto the surface of the lens to condense into a film. The driving member simultaneously drives the coating umbrella to rotate, thereby making the surface coating uniform.

[0005] The coating umbrella is an important device required in the coating treatment. During the production and manufacturing process, it is necessary to first punch out the positioning hole at the top, and then form a plurality of mounting holes. In the prior art, the forming process of the mounting hole is to use a positioning block processed by wire cutting. This requires prior drawing and manufacturing of an arc-shaped positioning block according to the number of opening holes, opening diameter, and opening gap of the optical coating umbrella to be opened. The manufacturing cost of the special positioning block is usually high, and the manufacturing time is also long; in addition, the special positioning block is difficult to meet different manufacturing requirements, and the mounting holes of the coating umbrella are used to place the optical lens to be coated. When the specifications of the optical lenses are different, the aperture of the required mounting holes and the gap between the holes are often different. At this time, a new positioning block needs to be prepared, resulting in high overall processing and manufacturing costs of the coating umbrella, long production and processing cycles, and low manufacturing efficiency. Summary of the Invention

[0006] In order to solve the problems existing in the above technology, this application provides a large optical coating umbrella forming device.

[0007] The large optical coating umbrella forming device provided by this application adopts the following technical solutions:

[0008] A large-scale optical coating umbrella forming device, comprising a mounting frame, a lower die table is arranged on the mounting frame, an upper die table is arranged on the mounting frame, the upper die table and the lower die table are arranged opposite to each other, a first driving member is arranged on the mounting frame, and the first driving member is used for driving the upper die table and the lower die table to perform opening and closing cooperation; a first fixing member for fixing the coating umbrella is arranged on the upper die table, a plurality of cutting tables are slidably arranged on the lower die table, and a second fixing member for fixing the cutting tables is arranged on the lower die table; a cutting member is arranged on each cutting table, a fixing seat is arranged on the cutting table, a second driving member is arranged on the fixing seat, and the second driving member is used for driving the cutting member to move in a direction away from or close to the fixing seat, and a third driving member for driving the cutting member to rotate is further arranged on the fixing seat, and a cavity for the cutting member to pass through is formed on the upper die table.

[0009] By adopting the above technical solution, when forming the mounting holes of the coating umbrella, the coating umbrella to be formed is fixed on the upper die table through the first fixing member, and then the first driving member drives the upper die table to move in a direction close to the lower die table, causing the upper die table and the lower die table to close. During this process, the coating umbrella between the upper die table and the lower die table contacts the cutting member. At the same time, the third driving member drives the cutting member to rotate, and the upper die table continues to press down with the coating umbrella, so that the cutting member cuts open the coating umbrella. During the rotation of the cutting member, the mounting holes are cut out, and the cutting member passes through the cavity. The rest of the coating umbrella is pressed between the upper die table and the lower die table, thus completing the forming process of the mounting holes of the coating umbrella; when the aperture of the required mounting hole needs to be adjusted, the second driving member drives the cutting member to move in a direction away from or close to the fixing seat, so as to change the distance between the cutting member and the fixing seat, and further change the aperture of the formed mounting hole; and when the gap between the mounting holes needs to be adjusted, slide the cutting table until there is a suitable gap between the plurality of cutting tables, and then fix the position of the cutting table at this time through the second fixing member; the cooperation of each component in the above process is used to form the mounting holes of the coating umbrella, and there is no need to make different positioning holes according to the requirements of different mounting holes, but the components can be flexibly adjusted according to the requirements of different mounting holes. The overall applicability of the device is high, it can cope with different manufacturing requirements, thereby improving the overall production and manufacturing efficiency of the coating umbrella and reducing the manufacturing cost at the same time.

[0010] Optionally, the cutting member includes a cutting edge arranged on the cutting table, and the top and side of the cutting edge are both in the shape of a sharp knife.

[0011] By adopting the above technical solution, during the process of the upper die table driving the coating umbrella to move towards the lower die table, the top of the coating umbrella first contacts the cutting edge. As the coating umbrella continues to be pressed down, the cutting edge penetrates the coating umbrella, and the third driving member drives the cutting edge to rotate. The side of the cutting edge contacts the coating umbrella and cuts during movement, thereby forming the installation hole.

[0012] Optionally, a burr brush is provided at the bottom of the cutting edge.

[0013] By adopting the above technical solution, after the installation hole of the coating umbrella is formed, the upper die table drives the coating umbrella to continue to be pressed down, and the third driving member drives the cutting edge to rotate. At this time, the burr brush at the bottom of the cutting edge contacts the side wall of the installation hole. During the rotation of the cutting edge, the burr brush rotates and remains in contact with the side wall of the installation hole, thereby removing the burrs generated during cutting, further improving the convenience of the device.

[0014] Optionally, the second driving member includes a first driving motor disposed on the fixed seat. The output shaft of the first driving motor is coaxially and fixedly connected with a bidirectional lead screw. Cutting edges are respectively fixed on two screw nuts of the bidirectional lead screw.

[0015] By adopting the above technical solution, the rotation of the output shaft of the first driving motor drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the two screw nuts to move. The two cutting edges are oppositely arranged, and the movement of the two lead screws drives the two cutting edges to move in a direction away from or close to each other, thereby realizing the change of the aperture size of the installation hole. By performing synchronous cutting treatment with the two cutting edges, the cutting efficiency can also be improved.

[0016] Optionally, the second driving member includes a first telescopic rod disposed on the fixed seat. The cutting edge is fixedly connected to the end of the first telescopic rod.

[0017] By adopting the above technical solution, the first telescopic rod is an electric telescopic rod. By controlling the telescopic movement of the first telescopic rod, the cutting edge can be driven to move, and the movement of the cutting edge realizes the change of the aperture size of the installation hole.

[0018] Optionally, a placement cavity is formed in the lower die table. A limiting groove communicating with the placement cavity is formed on the lower die table. A limiting seat is provided on the cutting table. The limiting seat is located in the limiting groove and is in sliding fit with the limiting groove; the second fixing member includes a base disposed in the placement cavity. A lifting member is provided on the base. A fixing rod is provided on the lifting member. The fixing rod is perpendicular to the lifting direction of the lifting member. A movable rod is coaxially and slidably connected in the fixing rod. The movable rod is hinged to the limiting seat.

[0019] By adopting the above technical solution, when the cutting table slides, the lifting member on the base drives the fixed rod to lift, so that the limiting seat slides in the limiting groove, the movable rod slides in the fixed rod, and the sliding of the limiting seat drives the cutting table to slide. When the cutting table slides to the required position, the lifting member stops operating, thereby fixing the position of the cutting table.

[0020] Optionally, the cutting tables are distributed in a multi-layer annular shape on the lower mold table. The lifting member includes a second telescopic rod and a plurality of matching tables. One end of the second telescopic rod is fixedly connected to the base, and the other end is fixedly connected to one of the matching tables. A plurality of fixed rods are vertically fixed on each matching table. The positions and quantities of the fixed rods correspond one by one to the positions and quantities of the cutting tables on each layer. A third telescopic rod is arranged between two adjacent matching tables.

[0021] By adopting the above technical solution, both the second telescopic rod and the third telescopic rod are electric telescopic rods. The telescopic movement of the second telescopic rod drives the matching table connected thereto to perform a lifting movement, thereby driving a plurality of movable rods on this fixed table to slide in the corresponding fixed rods, and the cutting tables on the corresponding layer slide synchronously. The stop of the telescopic movement of the second telescopic rod causes the cutting table to stop sliding. The sliding and stopping processes of the cutting tables on other layers are the same and can be achieved by driving with the third telescopic rod.

[0022] Optionally, the first fixing member includes a fixing block arranged on the first driving member. A screw rod is threadedly connected to the fixing block, and a pressing block is arranged on the screw rod. A pressing hole for the pressing block to insert is formed on the lower mold table.

[0023] By adopting the above technical solution, when fixing the coating umbrella, the screw rod is passed through the positioning hole of the coating umbrella, and then the screw rod is rotated to make the pressing block move in the direction close to the fixing block, so that the coating umbrella is pressed and fixed between the fixing block and the pressing block, thereby fixing the coating umbrella on the upper mold table. When the upper mold table drives the coating umbrella to move to fit with the lower mold table, the pressing block inserts into the pressing hole; the cooperation of each component in the above process utilizes the positioning hole at the top of the coating umbrella to fix the coating umbrella, and the fixing method is simple, flexible and easy to operate.

[0024] Optionally, a clamping plate for clamping the coating umbrella is rotatably connected to the upper mold table.

[0025] By adopting the above technical solution, after the coating umbrella is fixed on the upper mold table by the first fixing member, the coating umbrella is clamped between the upper mold table and the clamping plate by rotating the clamping plate, thereby improving the stability when the coating umbrella is fixed.

[0026] Optionally, a plurality of pressing plates are slidably arranged in the cavity. Each pressing plate includes a fixed plate and a movable plate. An adjusting cavity for the corresponding movable plate to slide is formed in the fixed plate. A plurality of sliding grooves are formed in the upper mold table. The same pressing plate is slidably fitted between two opposite sliding grooves. A first fastening screw is slidably arranged in one of the sliding grooves, and the first fastening screw is in threaded connection with the fixed plate. A second fastening screw is slidably arranged in the other sliding groove, and the second fastening screw is in threaded connection with the movable plate.

[0027] By adopting the above technical solution, during the process that the upper mold table drives the coating umbrella to move to close with the lower mold table, the cutting member contacts the coating umbrella and cuts it, and finally the cutting member passes through the cavity. The pressing plate is used to improve the stability during the cutting process and prevent the coating umbrella from deforming. The position of the pressing plate can be flexibly adjusted according to the position of the cutting table. When the position of the pressing plate needs to be adjusted, rotate the first fastening screw and the second fastening screw of the corresponding pressing plate, so that the pressing plate can slide, and the movable plate also slides adaptively in the fixed plate. Both the movable plate and the fixed plate are elastic plates. When the whole pressing plate slides to the required position, rotate the first fastening screw so that the end of the first fastening screw presses the corresponding fixed plate, and rotate the second fastening screw so that the end of the second fastening screw presses the corresponding movable plate, thereby realizing the fixation of the whole pressing plate.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The cooperation of each component during the forming process of the mounting block is used to form the mounting hole of the coating umbrella, and there is no need to make different positioning holes according to the requirements of different mounting holes, but the components can be flexibly adjusted according to the requirements of different mounting holes. The overall applicability of the device is high, which can meet different manufacturing requirements, thereby improving the overall production and manufacturing efficiency of the coating umbrella and reducing the manufacturing cost at the same time;

[0030] 2. After the mounting hole of the coating umbrella is formed, the upper mold table drives the coating umbrella to continue to press down, and the third driving member drives the cutting edge to rotate. At this time, the burr brush at the bottom of the cutting edge contacts the side wall of the mounting hole. During the rotation of the cutting edge, the burr brush rotates and keeps contacting the side wall of the mounting hole, so as to remove the burrs generated during cutting, thereby further improving the convenience of the device.

A third driving member 10 for driving the cutting member 8 to rotate is also arranged on the fixing seat 9, and a cavity 11 for the cutting member 8 to pass through is opened on the upper mold table 3.

[0043] Refer to Figure 3 and Figure 4 , the first driving member 4 is a pneumatic rod 41, the first fixing member 5 includes a fixing block 51 fixed to the movable end of the pneumatic rod 41, a screw rod 52 is threadedly connected to the fixing block 51, a pressing block 53 is arranged on the screw rod 52, and both sides of the pressing block 53 opposite to the fixing block 51 are arc-shaped. A pressing hole 12 for the pressing block 53 to insert is opened on the lower mold table 2, and a clamping plate 20 for clamping the coating umbrella is rotatably connected to the bottom inside the upper mold table 3; when fixing the coating umbrella, the screw rod 52 is passed through the positioning hole of the coating umbrella, and then the screw rod 52 is rotated so that the pressing block 53 moves in a direction close to the fixing block 51, so that the coating umbrella is pressed and fixed between the fixing block 51 and the pressing block 53. Then the clamping plate 20 at the bottom is rotated so that the bottom end of the coating umbrella is clamped between the upper mold table 3 and the clamping plate 20, so as to fix the coating umbrella on the upper mold table 3. The movement of the movable end of the pneumatic rod 41 can drive the upper mold table 3 to move, and the upper mold table 3 then drives the coating umbrella to move. When the upper mold table 3 drives the coating umbrella to move to fit with the lower mold table 2, the pressing block 53 inserts into the pressing hole 12.

[0044] Refer to Figure 2 and Figure 5 , the cutting tables 6 are distributed in a multi-layer ring shape on the lower mold table 2, a placement cavity 17 is opened inside the lower mold table 2, and an arc-shaped limiting groove 18 communicated with the placement cavity 17 is opened on the lower mold table 2. Refer to Figure 2 and Figure 6, a limit seat 19 is arranged on the cutting table 6. A notch is formed on the limit seat 19, and the notch surface is arc-shaped. The limit seat 19 is located in the limit groove 18 and is in sliding fit with the limit groove 18; the second fixing member 7 includes a base 71 and a plurality of fitting platforms 722. The base 71 is fixed in the placement cavity 17. A second telescopic rod 721 is arranged on the base 71. The fixed end of the second telescopic rod 721 is fixedly connected to the base 71. The movable end of the second telescopic rod 721 is fixedly connected to a fitting platform 722. A third telescopic rod 75 is arranged on the fitting platform 722. The fixed end of the third telescopic rod 75 is fixedly connected to a fitting platform 722, and the movable end is fixedly connected to another fitting platform 722. Adjacent fitting platforms 722 are connected by the third telescopic rod 75; a plurality of fixing rods 73 are perpendicularly fixed on each fitting platform 722. The positions and numbers of the fixing rods 73 correspond to the positions and numbers of the cutting tables 6 on each layer one by one. A movable rod 74 is coaxially and slidably connected in each fixing rod 73. The end of the movable rod 74 is hinged to the corresponding limit seat 19.

[0045] Both the second telescopic rod 721 and the third telescopic rod 75 are electric telescopic rods. The telescopic movement of the second telescopic rod 721 drives the fitting platform 722 connected thereto to perform a lifting movement, thereby driving a plurality of movable rods 74 on this fixed table to slide in the corresponding fixing rods 73, and the cutting tables 6 on the corresponding layer slide synchronously. The stop of the telescopic movement of the second telescopic rod 721 causes the cutting table 6 to stop sliding. The sliding and stopping processes of the cutting tables 6 on other layers are the same, which can be realized by driving the third telescopic rod 75.

[0046] Referring to Figure 5 and Figure 6 , the third driving member 10 includes a second driving motor 101 installed on the limit seat 19. The output shaft of the second driving motor 101 is fixedly connected to the cutting table 6. The cutting member 8 includes a cutting edge 81 arranged on the cutting table 6. The top and side of the cutting edge 81 are both in the shape of a sharp knife. A burr brush 13 is arranged at the bottom of the cutting edge 81; the second driving member includes a first driving motor 15 arranged on the fixed seat 9. The output shaft of the first driving motor 15 is coaxially and fixedly connected to a bidirectional lead screw 16. Cutting edges 81 are respectively fixed on the two lead screw nuts of the bidirectional lead screw 16.

[0047] In other embodiments, the cutting member 8 can also be a laser member, and the laser forming cutting of the mounting hole is performed by driving the laser member to rotate.

[0048] The rotation of the output shaft of the first drive motor 15 drives the double lead screw 16 to rotate. The rotation of the double lead screw 16 causes the two lead screw nuts to move. The two cutting edges 81 are arranged oppositely, and the movement of the two lead screws drives the two cutting edges 81 to move in a direction away from or close to each other, so as to change the aperture size of the mounting hole, and the two cutting edges 81 perform synchronous cutting; during the process of the upper mold table 3 driving the coating umbrella to move in the direction close to the lower mold table 2, the coating umbrella first contacts the top of the cutting edge 81. As the coating umbrella continues to press down, the cutting edge 81 penetrates the coating umbrella. The second drive motor 101 drives the cutting table 6 to rotate, thereby driving the cutting edge 81 to rotate. The side of the cutting edge 81 contacts the coating umbrella and cuts during the movement, so as to form the mounting hole; when the mounting hole of the coating umbrella is formed, the upper mold table 3 drives the coating umbrella to continue to press down, and the cutting edge 81 still rotates. At this time, the burr brush 13 at the bottom of the cutting edge 81 contacts the side wall of the mounting hole. During the rotation of the cutting edge 81, the burr brush 13 rotates and remains in contact with the side wall of the mounting hole, so as to remove the burrs generated during cutting, thereby further improving the convenience of the device.

[0049] Refer to Figure 1 and Figure 7 As shown in FIGS. 7 and 8, a plurality of pressing plates 21 are slidably arranged in the cavity 11. Each pressing plate 21 includes a fixing plate 211 and a movable plate 212. An adjustment cavity for the corresponding movable plate 212 to slide is formed in the fixing plate 211; a plurality of sliding grooves 22 are formed in the upper mold table 3. The same pressing plate 21 is slidably fitted between two opposite sliding grooves 22. A first fastening screw 23 is slidably arranged in one of the sliding grooves 22, and the first fastening screw 23 is threadedly connected to the fixing plate 211. A second fastening screw 24 is slidably arranged in the other sliding groove 22, and the second fastening screw 24 is threadedly connected to the movable plate 212; during the process of the upper mold table 3 driving the coating umbrella to move to close to the lower mold table 2, the cutting member 8 contacts the coating umbrella and cuts it. Finally, the cutting member 8 passes through the cavity 11. The pressing plate 21 is used to improve the stability during the cutting process and prevent the coating umbrella from deforming; the position of the pressing plate 21 is adjusted more flexibly according to the position of the cutting table 6. When the position of the pressing plate 21 needs to be adjusted, the first fastening screw 23 and the second fastening screw 24 of the corresponding pressing plate 21 are rotated, so that the pressing plate 21 can slide, and the movable plate 212 also slides adaptively in the fixing plate 211. The movable plate 212 and the fixing plate 211 are both elastic plates. When the whole pressing plate 21 slides to the required position, rotate the first fastening screw 23 so that the end of the first fastening screw 23 presses the corresponding fixing plate 211, and rotate the second fastening screw 24 so that the end of the second fastening screw 24 presses the corresponding movable plate 212, thereby realizing the fixation of the whole pressing plate 21.

[0050] The implementation principle of Embodiment 1 is as follows: When forming the mounting holes of the coated umbrella, the coated umbrella to be formed is fixed on the upper mold table 3 through the cooperation of the fixing block 51 and the pressing block 53. Subsequently, the air cylinder 41 drives the upper mold table 3 to move in the direction close to the lower mold table 2, causing the upper mold table 3 and the lower mold table 2 to close. During this process, the coated umbrella located between the upper mold table 3 and the lower mold table 2 contacts the cutting edge 81. At the same time, the second driving motor 101 drives the cutting edge 81 to rotate, and the upper mold table 3 continues to press down with the coated umbrella, so that the cutting edge 81 cuts open the coated umbrella. During the rotation of the cutting edge 81, the mounting holes are cut out. The cutting edge 81 passes through the cavity 11, and the rest of the coated umbrella is pressed between the upper mold table 3 and the lower mold table 2, thus completing the forming process of the mounting holes of the coated umbrella; When the aperture of the required mounting hole needs to be adjusted, the first driving motor 15 drives the two cutting edges 81 to move in the direction away from or close to each other, thereby changing the distance between the two cutting edges 81, and further changing the aperture of the formed mounting hole; And when the gap between the mounting holes needs to be adjusted, slide the cutting table 6 to ensure a suitable gap between the multiple cutting tables 6, and then fix the position of the cutting table 6 at this time through the cooperation of the second telescopic rod 721 and the third telescopic rod 75; The cooperation of each component in the above process is used to form the mounting holes of the coated umbrella, and there is no need to make different positioning holes according to the requirements of different mounting holes, but each component can be flexibly adjusted according to the requirements of different mounting holes. The overall applicability of the device is high, and it can meet different manufacturing requirements, thereby improving the overall production and manufacturing efficiency of the coated umbrella and reducing the manufacturing cost at the same time.

[0051] Embodiment 2

[0052] The difference between Embodiment 2 and Embodiment 1 is: Refer to Figure 8 , the second driving member includes an electric first telescopic rod 14 arranged on the fixed seat 9. The fixed end of the first telescopic rod 14 is fixedly connected to the fixed seat 9, and the movable end of the first telescopic rod 14 is fixedly connected to the cutting edge 81.

[0053] The implementation principle of Embodiment 2 is as follows: The first telescopic rod 14 is an electric telescopic rod. By controlling the telescopic movement of the first telescopic rod 14, the cutting edge 81 can be driven to move, and the movement of the cutting edge 81 realizes the change of the aperture size of the mounting hole.
