Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing equipment technology, and in particular to a fixing fixture that is compatible with various umbrella frames. Background Technology

[0002] After the lenses are cleaned by the dust removal equipment, the lens fixture containing the lenses needs to be unloaded onto the umbrella frame on the fixed fixture. Then, the umbrella frame is loaded into the lens coating machine for coating. The coating machine can usually only coat one side, so after coating, the umbrella frame needs to be returned to the original fixed fixture and loaded onto the dust removal equipment for dust removal on the other side. Different coating machines have different sizes, and the umbrella frame sizes that match each model of coating machine are different (e.g., fan-shaped single-piece umbrella frame, disc-shaped integral umbrella frame, etc.). Different coating machines are used according to different production needs, which requires the use of umbrella frames of different sizes. However, the existing umbrella frame fixing fixtures can only fix one type of umbrella frame, as shown in the patent document with publication number CN116855891A. Fixing different umbrella frames requires different umbrella frame fixing fixtures, and changing different fixing fixtures requires constant adjustment and alignment, which is time-consuming and labor-intensive. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a fixing fixture that is compatible with various umbrella frames.

[0004] This utility model is achieved by the following method: a fixing fixture compatible with multiple umbrella frames, including an umbrella frame platform, a first positioning component is provided in the middle of the umbrella frame platform, and a plurality of second positioning components are provided around the first positioning component on the umbrella frame platform.

The second positioning component includes a support positioning member disposed in the radial direction, and the support positioning member is provided with at least a first positioning portion and a second positioning portion. The support positioning member is connected to the support frame.

[0005] Preferably, the second support portion is a support ring disposed on the support frame, and the first support portion is a plurality of limiting posts disposed at intervals on the support ring.

[0006] Preferably, it also includes a third support portion, which is a plurality of protrusions arrayed on the outer peripheral surface of the support ring.

[0007] Preferably, the first positioning part is a first positioning block, which is installed on the upper surface of the support positioning member. The end of the first positioning block facing the first positioning component can abut against the circumferential surface of the integral umbrella frame. The second positioning part consists of two side surfaces adjacent to the end face of the first positioning block and the integral umbrella frame. These side surfaces can abut against the side surface of the single umbrella frame. The two side surfaces facing each other on the two adjacent support positioning members are interference-fitted with the two side surfaces corresponding to the single umbrella frame.

[0008] Preferably, it further includes a second positioning block, which is disposed on the upper surface of the support positioning member and located between the first positioning block and the first positioning component, with the first positioning block and the first positioning component being spaced apart.

[0009] Preferably, an umbrella frame top block is also installed on the side of the supporting positioning member, and the upper end surface of the umbrella frame top block is lower than the upper surface of the second positioning block to support the single umbrella frame.

[0010] Preferably, a rotary drive mechanism is also installed on the umbrella frame platform, and the support frame is installed on the rotary drive mechanism.

[0011] Preferably, an auxiliary support plate is connected between the ends of the two connected support positioning members that are away from the first positioning component, and the surfaces of the multiple auxiliary support plates opposite to the first positioning component are arranged in a circle; a top support member is also provided around the umbrella frame platform, and the auxiliary support plate is located above the top support member and can contact the top support member.

[0012] Preferably, the top support includes auxiliary support blocks and universal balls. A plurality of auxiliary support blocks are fixed to the outer peripheral surface of the umbrella frame platform. The universal balls are provided on the auxiliary support blocks and the universal balls are in contact with the lower surface of the auxiliary support plate. Limiting ribs are provided on the outer side of the upper surface of the auxiliary support plate.

[0013] Preferably, the umbrella frame platform is mounted on a moving mechanism, the moving mechanism including a moving drive and a moving guide, the umbrella frame platform being connected to the moving drive and the moving guide; the moving guide includes a guide rail and a slider, the slider being slidably mounted on the guide rail, the umbrella frame platform being fixedly connected to the slider, and buffers being provided at both ends of the guide rail.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a fixing fixture that is compatible with multiple umbrella frames. Compared with the prior art, this utility model has at least the following technical effects: 1. The combined structure of the central first positioning component and the surrounding second positioning component, through the cooperation of the first support part and the first positioning part to fix the integral umbrella frame, and through the cooperation of the second support part and the second positioning part to fix the single-piece umbrella frame, allows for switching of umbrella frame types without replacing the entire fixture, and can support multiple single-piece umbrella frames. It can simultaneously adapt to the support and positioning requirements of both integral and single-piece umbrella frames, eliminating complex debugging and alignment, reducing downtime, and improving production efficiency. 2. The spaced limiting posts can form multi-point stable support for the bottom of the integral umbrella frame, avoiding tilting of the integral umbrella frame due to uneven force at a single point, and limiting the longitudinal direction of the umbrella frame; the support ring can serve as a support structure for the single-piece umbrella frame, limiting the longitudinal direction of the umbrella frame. 3. The third support portion protruding from the outer periphery of the support ring can support a single-piece umbrella frame of another size, achieving longitudinal positioning. The difference from the previous single-piece umbrella frame lies in its radial dimension, enabling the positioning and support of a third-sized umbrella frame. 4. The end of the first positioning block limits the radial direction of the integral umbrella frame, cooperating with the limiting post to support the integral umbrella frame. Additionally, the side of the first positioning block can limit the side of the single-piece umbrella frame. Due to the interference fit, it can compress the single-piece umbrella frame, causing slight deformation within a certain range to clamp it, preventing the middle of the umbrella frame from collapsing and falling under gravity. Furthermore, by using the different support positions of the support ring and the boss, different positions can be achieved for supporting single-piece umbrella frames of different sizes. 5. A rotary drive mechanism is provided on the umbrella frame platform, which can drive the first and second positioning components to rotate and switch positions, facilitating the loading of single-piece umbrella frames to different positions. This eliminates the need for workers to rotate around the frame for loading; instead, the empty space is rotated to the worker's side. 6. The top support component is designed to provide support for the turntable, which is composed of the first and second positioning components, preventing tilting and jamming due to unilateral force and ensuring the turntable remains horizontal during rotation. 7. The entire umbrella frame platform is mounted on the moving mechanism, allowing it to move back and forth between the working position and the loading / unloading position, facilitating loading and unloading of the umbrella frame by staff.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figures 1 to 5 A fixing fixture compatible with various umbrella frames includes an umbrella frame platform 1. A first positioning component 2 is provided in the middle of the umbrella frame platform 1. A plurality of second positioning components 3 are provided around the first positioning component 2 on the umbrella frame platform 1. The first positioning component 2 includes a support frame 21 disposed on the umbrella frame platform 1. The support frame 21 is provided with at least a first support portion 22 and a second support portion 23. The second positioning components 3 include a support positioning member 31 disposed in the radial direction. The support positioning member 31 is provided with at least a first positioning portion and a second positioning portion. The support positioning member 31 is connected to the support frame 21. The combined structure of the central first positioning component 2 and the surrounding second positioning component 3 secures the integral umbrella frame through the cooperation of the first support part 22 and the first positioning part, and secures the single-piece umbrella frame through the cooperation of the second support part 23 and the second positioning part. This allows for switching between umbrella frame types without replacing the entire fixture. The space between the multiple second positioning components 3 can support multiple single-piece umbrella frames 7, simultaneously adapting to the support and positioning needs of both integral and single-piece umbrella frames. This eliminates complex adjustment and alignment, reduces downtime, and improves production efficiency. The installation height of the second positioning component 3 is lower than that of the first positioning component 2.

[0023] Please see Figures 1 to 5Preferably, the second support portion 23 is a ring provided on the support frame 21, and the first support portion 22 is a plurality of limiting posts provided on the ring at intervals. Of course, the second support portion 23 does not have to be annular; it can be a plurality of arc-shaped blocks arranged at intervals to form a circle, with the limiting posts located at the intervals. The spaced limiting posts can provide multi-point stable support for the bottom of the integral umbrella frame, avoiding tilting of the integral umbrella frame due to uneven force at a single point, and limiting the longitudinal direction of the umbrella frame; the ring can serve as a support structure for a single-piece umbrella frame, limiting the longitudinal direction of the umbrella frame.

[0024] Please see Figures 1 to 5 Preferably, it also includes a third support portion 24, which is a plurality of protrusions arrayed on the outer circumferential surface of the support ring. The third support portion 24 and the first support portion 22 need to be circumferentially offset. The third support portion 24 protruding from the outer circumference of the support ring can support a single-piece umbrella frame of another size, achieving longitudinal direction limiting. The difference from the first single-piece umbrella frame 7 is that the radial direction dimension is different, realizing the positioning and support of the third size umbrella frame. There is also another type of single-piece umbrella frame 7, which differs from the previous two in that the overall size remains the same, only the number of slots for placing lens fixtures is different, so it can also be compatible with this type of single-piece umbrella frame 7.

[0025] Please see Figure 1 , 3 , Figure 5 Preferably, the first positioning part is a first positioning block 32, which is installed on the upper surface of the support positioning member 31. The end of the first positioning block 32 facing the first positioning component 2 can abut against the circumferential surface of the integral umbrella frame. The second positioning part consists of the two side surfaces of the first positioning block 32 adjacent to the end face of the integral umbrella frame. These side surfaces can abut against the side surface of the single umbrella frame 7. The two side surfaces facing each other on the two adjacent support positioning members 31 are interference-fitted with the two corresponding side surfaces of the single umbrella frame 7. The end of the first positioning block 32 limits the radial direction of the integral umbrella frame and cooperates with the limiting post to limit and support the integral umbrella frame 6. In addition, the side surface of the first positioning block 32 can limit the side surface of the single umbrella frame 7. Due to the interference fit, the single umbrella frame 7 can be squeezed to deform slightly within a certain range to clamp the single umbrella frame and prevent the middle part of the umbrella frame from collapsing and sagging due to gravity. Furthermore, by using different support positions of the support ring and the boss, different positions can be achieved to support single umbrella frames 7 of different sizes.

[0026] Please see Figure 1 , Figure 3 , Figure 5Preferably, it further includes a second positioning block 33, which is disposed on the upper surface of the supporting positioning member 31, located between the first positioning block 32 and the first positioning component 2, with the first positioning block 32 and the first positioning component 2 spaced apart. The second positioning block 33 provides support for the overall umbrella frame 6, and its upper surface is arc-shaped to prevent it from sagging and deforming under gravity. The upper surface of the second positioning block 33 is arc-shaped.

[0027] Please see Figure 1 to, Figure 3 Preferably, the side of the supporting positioning member 31 is also equipped with an umbrella frame top block 34. The upper surface of the umbrella frame top block 34 is lower than the upper surface of the second positioning block 33 to support the single umbrella frame 7. Adjacent to the second positioning block 33, this umbrella frame top block 34 forms a "bottom support" for the single umbrella frame 7, avoiding the problem of the side center sagging caused by the single umbrella frame 7 being positioned only by the radial ends (the sagging amount is reduced from 0.4mm to 0.1mm), ensuring the levelness of the lens on the umbrella frame, and preventing uneven spacing between the lens and the coating machine nozzle during coating. The height of the umbrella frame top block 34 can be adjusted by replacing the top block with one of different thicknesses (e.g., using a top block with a height of 20mm to accommodate a thicker single umbrella frame 7).

[0028] Please see Figures 1 to 5 Preferably, a rotary drive mechanism 4 is also installed on the umbrella frame platform 1, and the support frame 21 is installed on the rotary drive mechanism 4. The rotary drive mechanism 4 on the umbrella frame platform 1 can drive the first positioning component 2 and the second positioning component 3 to rotate and switch positions, facilitating the loading of single umbrella frame pieces 7 to different positions without requiring workers to rotate around it for loading; instead, the empty space is rotated to the worker's side. The rotary drive mechanism 4 can be composed of a motor, etc., which is existing technology and will not be described in detail or subject to specific protection requirements.

[0029] Please see Figures 1 to 5 Preferably, an auxiliary support plate 35 is connected between the ends of the two connected support positioning members 31 that are away from the first positioning component 2. Multiple auxiliary support plates 35 are arranged in a circle around the surface of the support facing away from the first positioning component 2. A top support is also provided around the umbrella frame platform 1, and the auxiliary support plates 35 are located above the top support, allowing them to contact each other. The top support is used to support the turntable formed by the first positioning component 2 and the second positioning component 3, preventing tilting and jamming due to unilateral force, and keeping the turntable horizontal during rotation.

[0030] Please see Figure 2 , Figure 4Preferably, the top support includes auxiliary support blocks 11 and universal balls 12. Multiple auxiliary support blocks 11 are fixed to the outer periphery of the umbrella frame platform 1. Universal balls 12 are mounted on the auxiliary support blocks 11 and contact the lower surface of the auxiliary support plate 35. Limiting ribs are provided on the outer side of the upper surface of the auxiliary support plate 35. The universal balls 12 facilitate smoother rotation of the turntable formed by the first positioning component 2 and the second positioning component 3. The limiting ribs can block and limit the movement of the single-piece umbrella frame away from the first positioning component 2.

[0031] Please see Figures 1 to 5 Preferably, the umbrella frame platform 1 is mounted on the moving mechanism 5. The moving mechanism 5 includes a moving drive component 51 and a moving guide component 52. The umbrella frame platform 1 is connected to the moving drive component 51 and the moving guide component 52. The moving guide component 52 includes a guide rail and a slider. The slider is slidably mounted on the guide rail, and the umbrella frame platform 1 is fixedly connected to the slider. Buffers 53 are provided at both ends of the guide rail. Mounting the entire umbrella frame platform 1 on the moving mechanism 5 allows it to move back and forth between the working position and the pick-up / placement position, facilitating loading or unloading of the umbrella frame by the operator. The moving drive component 51 can be a cylinder, a linear module, etc., and is not limited thereto.

[0032] The working principle of this utility model is as follows: Initial state: The moving mechanism 5 moves the umbrella frame platform 1 to the unloading station of the dust removal equipment (the slider is driven to slide along the guide rail by the moving drive component 51, and the buffers 53 at both ends of the guide rail ensure that the umbrella frame platform 1 is accurately stopped). The rotating drive mechanism 4 is in standby state, and the auxiliary support plate 35 maintains slight contact with the universal ball 12 of the top support component.

[0033] Umbrella frame fixing (taking an integral frame as an example): Place the entire umbrella frame 6 at the center of the limit post supporting the entire umbrella frame 6; make the perimeter of the umbrella frame abut against the end face of the first positioning block 32, and prevent the entire umbrella frame from shifting through the "encircling" positioning of multiple first positioning blocks 32. Umbrella frame fixing (taking a single-piece umbrella frame as an example): The single-piece umbrella frame 7 is placed on the upper surface of the support ring with its center side supported. The two side edges of the single-piece umbrella frame 7 abut against the sides of the first positioning block 32. The sides of the first positioning block 32 of the adjacent support positioning member 31 form an interference fit with the two sides of the single-piece umbrella frame 7, which can compress the single-piece umbrella frame 7 to make it deform slightly within a certain range, thus clamping the single-piece umbrella frame and preventing the middle of the umbrella frame from collapsing and falling due to gravity. At the same time, the top block 34 of the umbrella frame supports the middle of the side of the single-piece umbrella frame 7 from the bottom, preventing it from sagging or shifting. The other two types of single-piece umbrella frames 7 are supported on the boss with the center side supported, and other aspects remain unchanged. The turntable composed of the first positioning component 2 and the second positioning component 3 can be rotated by the rotary drive mechanism 4, so that the other space enclosed by the support positioning member 31 without an umbrella frame is rotated to a position facing the staff, and the installation of the next single-piece umbrella frame 7 can then proceed. After the umbrella frame is installed, the umbrella frame platform 1 is moved to the position where the dust removal mechanism docks with the material feeding position via the moving mechanism 5; when the umbrella frame needs to be removed, the umbrella frame platform 1 is moved in the opposite direction via the moving mechanism 5 to a position where it is convenient to disassemble and assemble the umbrella frame.
