Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to a feeding mechanism for an optical lens laminating machine. Background Art

[0002] After the optical lens is processed, it is necessary to use a laminating machine to laminate both sides of the optical lens for packaging. When the existing optical lens laminating machine (such as a lens laminating machine disclosed in the application number 201620298910.7) laminates and packages both sides of the optical lens, first, the lower film is laid flat on the laminating platform, and then the optical lenses are placed on the lower film at intervals one by one manually. The motor drives the lower pressure roller to rotate, and then drives the lower film to translate, thereby driving the optical lenses on the lower film to move. When the optical lens moves directly below the upper pressure roller, the reverse friction force causes the upper pressure roller to rotate in the reverse direction, so as to complete the laminating process on both sides of the optical lens. However, the above laminating machine lacks a corresponding feeding mechanism, and it is necessary to manually place the optical lenses on the lower film in sequence. When laminating a batch of optical lenses, it is easy to increase the labor intensity of workers. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above technical deficiencies, and propose a feeding mechanism for an optical lens laminating machine, which solves the technical problem that the existing optical lens laminating machine lacks a corresponding feeding mechanism, and it is necessary to manually place the optical lenses on the lower film in sequence. When laminating a batch of optical lenses, it is easy to increase the labor intensity of workers.

[0004] To achieve the above technical purpose, the technical solution of the utility model provides a feeding mechanism for an optical lens laminating machine, which is arranged directly above the laminating platform of the laminating machine and includes:

[0005] A storage hopper for placing optical lenses from bottom to top therein;

[0006] A material distribution assembly, which includes a material blocking member and a pressing member. The pressing member is arranged directly above the material blocking member, and the distance between the pressing member and the material blocking member is greater than the thickness of a single optical lens and less than the thickness of two optical lenses;

[0007] A driving assembly, which is connected to both the material blocking member and the pressing member, and is used to drive the material blocking member and the pressing member to move in opposite directions horizontally, so that the material blocking member blocks or releases the optical lenses, and the pressing member correspondingly releases or presses against the side wall of the upper layer of optical lenses.

[0008] Furthermore, the storage hopper has a storage cavity, the upper surface and the lower surface of the storage cavity are both open, and each optical lens is placed in the storage cavity from bottom to top.

[0009] Further, the material storage cavity is of a columnar structure, and the side wall of the material storage cavity is equal to the diameter of the optical lens.

[0010] Further, a first notch communicating with the material storage cavity is formed in the side wall of the material storage hopper, and the first notch is used for the blocking member to slide through.

[0011] Further, a second notch communicating with the material storage cavity is further formed in the side wall of the material storage hopper. The second notch is located directly above the first notch and is used for the pressing member to slide through.

[0012] Further, the feeding mechanism for the optical lens laminating machine further includes a bracket. The material storage hopper is fixed on the bracket, and both the blocking member and the pressing member are slidably arranged on the bracket.

[0013] Further, the driving assembly includes a telescopic driving member, an elastic member, an iron block and a magnet. The telescopic driving member is fixed on the bracket, and the output end of the telescopic driving member is fixedly connected to the end of the blocking member away from the material storage hopper, so that the end of the blocking member close to the material storage hopper moves into or out of the material storage cavity. Both ends of the elastic member are fixedly connected to the bracket and the end of the pressing member away from the material storage hopper respectively, so that the end of the pressing member close to the material storage hopper presses against the side wall of the upper layer of optical lenses. The iron block is fixed on the blocking member and close to the material storage hopper, and the magnet is fixed on the pressing member and close to the material storage hopper. The magnet is magnetically connected to the iron block. When the end of the blocking member close to the material storage hopper is located in the material storage cavity, the magnet is attracted to the iron block, and the end of the pressing member close to the material storage hopper is located outside the material storage cavity.

[0014] Further, the elastic member is a spring.

[0015] Further, a first sliding groove is formed on the bracket. The first sliding groove extends horizontally along the radial direction of the material storage cavity and corresponds to the first notch. The end of the blocking member away from the material storage hopper is slidably arranged in the first sliding groove.

[0016] Further, a second sliding groove is formed on the bracket. The second sliding groove extends horizontally along the radial direction of the material storage cavity and corresponds to the second notch.

By operating the driving component, the driving component drives the material blocking member and the pressing member to move in opposite directions horizontally, so that the material blocking member releases the lowermost optical lens. At this time, the pressing member will press against the side wall of the upper layer of optical lens, so that the upper layer of optical lens cannot move downward, thereby feeding the film at intervals downward. There is no need for manual placement of optical lenses on the lower film in sequence, which can reduce the labor intensity of workers when laminating optical lenses in batches.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] The present utility model provides a feeding mechanism for an optical lens laminating machine, which is arranged directly above the laminating platform of the laminating machine, and its structure is as Figure 1 - Figure 3As shown in the figure, it includes a storage hopper 100, a material distribution component 200 and a driving component 300. Optical lenses are placed in the storage hopper 100 from bottom to top. The material distribution component 200 includes a material blocking member 210 and a pressing member 220. The pressing member 220 is arranged directly above the material blocking member 210, and the distance between the pressing member 220 and the material blocking member 210 is greater than the thickness of a single optical lens and less than the thickness of two optical lenses. The driving component 300 is connected to both the material blocking member 210 and the pressing member 220, and is used to drive the material blocking member 210 and the pressing member 220 to move in opposite directions horizontally, so that the material blocking member 210 blocks or releases the optical lens, and the pressing member 220 correspondingly loosens or presses against the side wall of the upper layer of optical lens.

[0024] During use, by controlling the driving component 300, the driving component 300 is made to drive the material blocking member 210 and the pressing member 220 to move in opposite directions horizontally, so that the material blocking member 210 blocks the optical lens. Each optical lens to be coated is placed in the storage hopper 100 from bottom to top. The lowermost optical lens abuts against the material blocking member 210. By controlling the driving component 300, the driving component 300 is made to drive the material blocking member 210 and the pressing member 220 to move in opposite directions horizontally, so that the material blocking member 210 releases the lowermost optical lens. At this time, the pressing member 220 will press against the side wall of the upper layer of optical lens, so that the upper layer of optical lens cannot move downward, thereby feeding materials at intervals onto the lower film. There is no need for manual placement of optical lenses on the lower film in sequence, which can reduce the labor intensity of workers when batch coating optical lenses.

[0025] As a preferred embodiment, please refer to Figure 2 , the storage hopper 100 has a storage cavity 110. The upper surface and the lower surface of the storage cavity 110 are both open. Each optical lens is placed in the storage cavity 110 from bottom to top. Through the opening on the upper surface of the storage cavity 110, a relatively large number of optical lenses can be placed in the storage cavity 110 at one time. The optical lenses in the storage cavity 110 can fall onto the lower film along the opening on its lower surface.

[0026] As a preferred embodiment, please refer to Figure 2 , the storage cavity 110 is of a columnar structure, and the side wall of the storage cavity 110 is equal to the diameter of the optical lens, which can improve the limiting effect of the storage cavity 110 on the optical lens.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3, a first notch 120 communicating with the storage cavity 110 is formed in the side wall of the storage hopper 100. The first notch 120 is used for the baffle 210 to slide through, so that the baffle 210 can enter the storage cavity 110 along the first notch 120.

[0028] As a preferred embodiment, please refer to Figure 2 and Figure 3 , a second notch 130 communicating with the storage cavity 110 is further formed in the side wall of the storage hopper 100. The second notch 130 is located directly above the first notch 120 and is used for the pressing member 220 to slide through, so that the pressing member 220 can enter the storage cavity 110 along the first notch 120.

[0029] As a preferred embodiment, please refer to Figure 2 , the feeding mechanism for the optical lens laminating machine further includes a bracket 400. The storage hopper 100 is fixed on the bracket 400. The baffle 210 and the pressing member 220 are both slidably arranged on the bracket 400. The bracket 400 can support the storage hopper 100, the baffle 210 and the pressing member 220.

[0030] As a preferred embodiment, please refer to Figure 2 and Figure 3, the driving assembly 300 includes a telescopic driving member 310, an elastic member 320, an iron block 330 and a magnet 340. The telescopic driving member 310 is fixedly arranged on the bracket 400, and the output end of the telescopic driving member 310 is fixedly connected to the end of the material blocking member 210 away from the storage hopper 100, so that the end of the material blocking member 210 close to the storage hopper 100 moves into or out of the storage cavity 110. The two ends of the elastic member 320 are respectively fixedly connected to the bracket 400 and the end of the pressing member 220 away from the storage hopper 100, so that the end of the pressing member 220 close to the storage hopper 100 presses against the side wall of the upper layer of optical lenses. The iron block 330 is fixedly arranged on the material blocking member 210 and close to the storage hopper 100, and the magnet 340 is fixedly arranged on the pressing member 220 and close to the storage hopper 100. The magnet 340 is magnetically connected to the iron block 330. When the end of the material blocking member 210 close to the storage hopper 100 is located in the storage cavity 110, the magnet 340 and the iron block 330 are attracted to each other, and the end of the pressing member 220 close to the storage hopper 100 is located outside the storage cavity 110. When feeding materials onto the lower film, by controlling the telescopic driving member 310, the telescopic driving member 310 can drive the end of the material blocking member 210 close to the storage hopper 100 to move out of the storage cavity 110. At this time, the lowermost layer of optical lenses will fall onto the lower film. Since the end of the material blocking member 210 close to the storage hopper 100 moves out of the storage cavity 110, it will drive the iron block 330 to move away from the storage hopper 100, and drive the pressing member 220 to move away from the storage hopper 100 via the magnet 340, thereby squeezing the elastic member 320, so that the elastic member 320 accumulates compressed elastic potential energy and applies an elastic thrust to the pressing member 220. When the elastic thrust applied by the elastic member 320 to the pressing member 220 is greater than the suction force between the magnet 340 and the iron block 330, the magnet 340 and the iron block 330 are separated, and the elastic member 320 releases the compressed elastic potential energy, so that the end of the pressing member 220 close to the storage hopper 100 enters the storage cavity 110 and presses against the side wall of the upper layer of optical lenses. After the lowermost layer of optical lenses falls onto the lower film, by controlling the telescopic driving member 310 again, the telescopic driving member 310 can drive the end of the material blocking member 210 close to the storage hopper 100 to move into the storage cavity 110. During the process that the end of the material blocking member 210 close to the storage hopper 100 moves into the storage cavity 110, it will drive the iron block 330 to move towards the storage hopper 100. When the distance between the iron block 330 and the magnet 340 is relatively close, the suction force between the magnet 340 and the iron block 330 will be greater than the elastic thrust of the elastic member 320 on the pressing member 220.The magnet 340 is magnetically attracted to the iron block 330, so that one end of the pressing member 220 close to the storage hopper 100 is located outside the storage cavity 110 again. The optical lens in the storage cavity 110 drops and is blocked by the baffle member 210.

[0031] As a preferred embodiment, please refer to Figure 2 , the elastic member 320 is a spring, which can accumulate compressive elastic potential energy when subjected to pressure and release the compressive elastic potential energy when the pressure disappears.

[0032] As a preferred embodiment, please refer to Figure 2 , a first chute 410 is formed on the bracket 400. The first chute 410 extends horizontally along the radial direction of the storage cavity 110 and corresponds to the first notch 120. One end of the baffle member 210 away from the storage hopper 100 is slidably disposed in the first chute 410, and the elastic member 320 is disposed in the first chute 410. The movement of the baffle member 210 can be guided through the first chute 410.

[0033] As a preferred embodiment, please refer to Figure 2 , a second chute 420 is formed on the bracket 400. The second chute 420 extends horizontally along the radial direction of the storage cavity 110 and corresponds to the second notch 130. One end of the pressing member 220 away from the storage hopper 100 is slidably disposed in the second chute 420. The movement of the pressing member 220 can be guided through the second chute 420.

[0034] As a preferred embodiment, please refer to Figure 2 , the baffle member 210 is a plate-like structure. Since the optical lens is relatively thin, the plate-like baffle member 210 can be adapted to the optical lens.

[0035] As a preferred embodiment, please refer to Figure 2 , one end of the baffle member 210 close to the storage hopper 100 is an arc structure, and its radian is the same as the radian of the side wall of the optical lens, which can improve the pressing effect on the side wall of the optical lens.

[0036] As a preferred embodiment, please refer to Figure 2 , one end of the baffle member 210 close to the storage hopper 100 has an elastic structure and is made of rubber material, which can further improve the pressing effect on the side wall of the optical lens.

[0037] As a preferred embodiment, please refer to Figure 2 , the pressing member 220 is a plate-like structure. Since the optical lens is relatively thin, the plate-like pressing member 220 can be adapted to the optical lens.

[0038] To better understand the present utility model, the working principle of the technical solution of the present utility model will be described in detail below in conjunction with Figure 1 - Figure 3 :

[0039] During use, one end of the material blocking member 210 close to the storage hopper 100 is located inside the storage cavity 110. At this time, the magnet 340 is attracted to the iron block 330, and one end of the pressing member 220 close to the storage hopper 100 is located outside the storage cavity 110. Each optical lens to be coated is placed into the storage cavity 110 from bottom to top, and the lowermost optical lens abuts against the material blocking member 210. When feeding the film downwards, by controlling the telescopic driving member 310, the telescopic driving member 310 can drive one end of the material blocking member 210 close to the storage hopper 100 to move out of the storage cavity 110. At this time, the lowermost optical lens will fall onto the lower film. Since, during the process of one end of the material blocking member 210 close to the storage hopper 100 moving out of the storage cavity 110, it will drive the iron block 330 to move away from the storage hopper 100, and drive the pressing member 220 to move away from the storage hopper 100 via the magnet 340, thereby squeezing the elastic member 320, causing the elastic member 320 to accumulate compressive elastic potential energy and exert an elastic thrust on the pressing member 220. When the elastic thrust exerted by the elastic member 320 on the pressing member 220 is greater than the attractive force between the magnet 340 and the iron block 330, the magnet 340 and the iron block 330 separate, and the elastic member 320 releases the compressive elastic potential energy, causing one end of the pressing member 220 close to the storage hopper 100 to enter the storage cavity 110 and abut against the side wall of the upper layer of optical lenses, preventing the upper layer of optical lenses from moving downwards. When the lowermost optical lens falls onto the lower film, by controlling the telescopic driving member 310 again, the telescopic driving member 310 can drive one end of the material blocking member 210 close to the storage hopper 100 to move into the storage cavity 110. During the process of one end of the material blocking member 210 close to the storage hopper 100 moving into the storage cavity 110, it will drive the iron block 330 to move towards the storage hopper 100. When the distance between the iron block 330 and the magnet 340 is relatively close, the attractive force between the magnet 340 and the iron block 330 will be greater than the elastic thrust of the elastic member 320 on the pressing member 220, and the magnet 340 and the iron block 330 are magnetically attracted, causing one end of the pressing member 220 close to the storage hopper 100 to be located outside the storage cavity 110 again. The optical lenses in the storage cavity 110 fall and are blocked by the material blocking member 210, preparing for the next feeding. This feeding mechanism can feed the lower film at intervals, eliminating the need for manual placement of optical lenses on the lower film one by one, and reducing the labor intensity of workers during batch coating of optical lenses.

[0040] The feeding mechanism for an optical lens laminating machine provided by the present utility model has the following beneficial effects:

[0041] (1) When feeding the lower film, by controlling the telescopic driving member 310, the telescopic driving member 310 can drive one end of the material blocking member 210 close to the storage hopper 100 to move out of the storage cavity 110. At this time, the lowermost optical lens will fall onto the lower film. Since the process of one end of the material blocking member 210 close to the storage hopper 100 moving out of the storage cavity 110 will drive the iron block 330 to move away from the storage hopper 100, and drive the pressing member 220 to move away from the storage hopper 100 via the magnet 340, thereby squeezing the elastic member 320, causing the elastic member 320 to accumulate compressive elastic potential energy and applying an elastic thrust to the pressing member 220. When the elastic thrust applied by the elastic member 320 to the pressing member 220 is greater than the suction force between the magnet 340 and the iron block 330, the magnet 340 and the iron block 330 are separated, and the elastic member 320 releases the compressive elastic potential energy, so that one end of the pressing member 220 close to the storage hopper 100 enters the storage cavity 110 and presses against the side wall of the upper layer of optical lenses, preventing the upper layer of optical lenses from moving downward;

[0042] (2) After the lowermost optical lens falls onto the lower film, by controlling the telescopic driving member 310 again, the telescopic driving member 310 can drive one end of the material blocking member 210 close to the storage hopper 100 to move into the storage cavity 110. During the process of one end of the material blocking member 210 close to the storage hopper 100 moving into the storage cavity 110, it will drive the iron block 330 to move towards the storage hopper 100. When the distance between the iron block 330 and the magnet 340 is relatively close, the suction force between the magnet 340 and the iron block 330 will be greater than the elastic thrust of the elastic member 320 on the pressing member 220. The magnet 340 and the iron block 330 are magnetically attracted, so that one end of the pressing member 220 close to the storage hopper 100 is located outside the storage cavity 110 again. The optical lenses in the storage cavity 110 fall and are blocked by the material blocking member 210, realizing material separation;

[0043] (3) This feeding mechanism can feed the lower film at intervals, eliminating the need for manual placement of optical lenses on the lower film one by one. When laminating optical lenses in batches, the labor intensity of workers can be reduced.

[0044] The above specific implementation manners of the present utility model do not limit the protection scope of the present utility model.
