Description

Technical Field

[0001] The invention relates to the technical field of optical lens assembly equipment, and in particular to a light and small material feeder for optical lens assembly. Background Art

[0002] At present, there are three main ways to feed light and small materials used in optical lens assembly: 1. Manual feeding; 2. Circular rigid vibration plate feeding; 3. Flexible vibration plate feeding.

[0003] The first one is manual loading: that is, the material is placed manually by the operator.

[0004] The second method is to load materials using a circular rigid vibrating plate: There is a pulse electromagnet under the hopper, which can make the hopper vibrate vertically up and down. Due to the tilt of the spring, the hopper vibrates around its vertical axis. The parts inside the hopper rise along the spiral track due to this vibration. When a material comes out along the track, it is immediately sucked away by the suction cup robot.

[0005] The third type is flexible vibration plate material separation: the flexible vibration plate can move the parts on the surface of the plate in any direction. The vibration plate realizes automatic separation of materials by vibrating and flipping the parts, so that there is a certain distance between each material, which is convenient for the robot to grab; the second is to use CCD to shoot the plate to obtain the exact position of the material, and then use the suction cup robot to absorb it.

[0006] Among them, the main problems of manual loading are high labor costs and low production efficiency.

[0007] The circular rigid vibration plate feeding requires the design of vibration plates of different structures according to different product structures, so the feeding compatibility is relatively poor, and for very light materials, such as shading sheets, vibration cannot be used to achieve the purpose of feeding.

[0008] Flexible vibrators are also used for materials with a certain weight to isolate and separate them for better material removal. Similarly, flexible vibrators cannot separate light-weight materials such as shading sheets that have static electricity.

[0009] Therefore, based on the above-mentioned defects of the existing light and small material feeding method for optical lens assembly, it is necessary to improve the existing light and small material feeding method for optical lens assembly. Summary of the invention

[0010] The purpose of the present invention is to provide a light and small material feeder for optical lens assembly in view of the deficiencies in the prior art, which solves the defects of the existing light and small material feeding method for optical lens assembly, such as poor feeding compatibility.

[0011] To achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a light and small material feeder for optical lens assembly, including a workbench, on which a horizontal flipping device and a moving component are arranged, the flipping device has a vacuum adsorption plane, and the moving component is connected to a horizontal push-pull cylinder; the moving component includes a material drawer and a moving seat, the material drawer is movably located below the moving seat, the bottom end of the moving seat is open, the material drawer has a material groove, the moving seat is horizontally provided with a through hole for the flipping device to pass through, and the moving seat is movably sleeved outside the flipping device.

[0012] Furthermore, a plurality of bottom blowing holes are provided at the bottom of the material trough for blowing up the material.

[0013] Furthermore, the vacuum adsorption plane is provided with a plurality of material adsorption pores for adsorbing materials.

[0014] Furthermore, the flipping device includes a rotating shaft and an adsorption section, and the outer end of the rotating shaft has a gear section; the adsorption section has multiple vacuum adsorption planes, and the flipping device can realize the alternating operation of multiple vacuum adsorption planes.

[0015] Furthermore, a material collecting box is provided below the moving component for collecting fallen materials.

[0016] Furthermore, the flipping device includes a left flipping device and a right flipping device, and the left flipping device and the right flipping device are symmetrically arranged and connected through a horizontal axis, which can improve production efficiency.

[0017] Furthermore, both sides of the lower end of the movable seat are provided with L-shaped support plates, and both sides of the material drawer are respectively protruded to form convex ridges, and the convex ridges are located on the support plates to facilitate the taking and placing of the material drawer.

[0018] Furthermore, the gear segment is sleeved with a synchronous belt, which is driven by a motor, and the motor drives the flipping device to achieve flipping.

[0019] Furthermore, the gear segment is meshed with a rack, and the rack is driven by a lifting cylinder, so that the turning device is turned over by a gear and rack driving method.

[0020] Furthermore, the moving assembly is connected to a horizontal push-pull cylinder for driving the moving assembly to move.

[0021] The beneficial effects of the present invention are: by vacuum-adsorbing the material through the flipping device and flipping it to wait for material collection, the feeding of light-weight objects (such as shading sheets) can be effectively and reliably solved, and the feeding types are highly compatible, and other light-weight materials of different sizes can also be applied, and the feeding efficiency is high.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] See Figure 1 —— Figure 5 , Embodiment 1 of the present invention comprises: a workbench 1, a left bracket 2 and a right bracket 3 are arranged on the workbench 1, a left flipping device 4 and a moving assembly 8 are arranged between the left bracket 2 and the right bracket 3, the left flipping device 4 is arranged horizontally and can realize horizontal flipping, the moving assembly 8 moves horizontally, the moving assembly 8 comprises a material drawer 9 and a moving seat 25, the material drawer 9 is located below the moving seat 25, the material drawer 9 is used to place materials and can move with the moving seat 25, the moving seat 25 is horizontally provided with a through hole 26 and a accommodating space 28 for accommodating the left flipping device 4 is formed in the moving seat 25, when the moving seat 25 moves, the through hole 26 is gradually inserted into the left flipping device 4 until the left flipping device 4 completely enters the accommodating space 28 of the moving seat 25, when the moving seat 25 moves in the reverse direction, the left flipping device 4 is located outside the moving seat 25.

[0032] like Figure 3 As shown, the left flipping device 4 of the present invention includes a rotating shaft 12 and an adsorption section 13. The outer end of the rotating shaft 12 has a gear section 17. The adsorption section 13 has a plurality of vacuum adsorption planes 15. The vacuum adsorption planes 15 are provided with a plurality of material adsorption pores 16. The material adsorption pores 16 suck air outward to form a vacuum and adsorb the material 34. The two sides of the vacuum adsorption plane 15 are respectively provided with side blocks 14. The side blocks 14 have arc-shaped edges. The side blocks 14 are used to match the through holes 26 of the movable seat 25 and can cause disturbances in the airflow in the accommodating space 28.

[0033] A left flipping device 4 and a right flipping device 5 are arranged between the left bracket 2 and the right bracket 3 of the present invention. The left flipping device 4 and the right flipping device 5 are coaxially symmetrically arranged, and the left flipping device 4 and the right flipping device 5 are connected by a horizontal axis. The left flipping device 4 and the right flipping device 5 can both be flipped horizontally. The moving component 8 can move between the left flipping device 4 and the right flipping device 5 in turn, so that the left flipping device 4 and the right flipping device 5 can work separately, and material taking and feeding can be carried out simultaneously, thereby improving work efficiency.

[0034] The outer end of the adsorption section 13 of the left flipping device 4 and the right flipping device 5 of the present invention is formed with a connection hole 20, and the horizontal shaft is inserted into the connection hole 20 to facilitate the flipping of the left flipping device 4 and the right flipping device 5.

[0035] See Figure 4 , Figure 5 The pulling direction of the material drawer 9 of the present invention is perpendicular to the central axis of the through hole 26. The lower ends of the movable seat 25 are provided with L-shaped support plates 29 on both sides, and the material drawer 9 is directly placed on the support plates 29, or, as shown in the figure, the two sides of the material drawer 9 are respectively protruded to form convex ridges 23, and the convex ridges 23 are located on the support plates 29.

[0036] The material drawer 9 of the present invention has a material slot 21 in the middle, and the material slot 21 is used to place the material 34. The front end of the material drawer 9 has a handle 24, and the handle 24 is used to pull the material drawer 9.

[0037] The bottom surface of the material trough 21 of the present invention has a plurality of bottom blowing holes 22. When the bottom blowing holes 22 are ventilated upward, the material 34 placed in the material trough 21 can be blown upward.

[0038] The bottom end of the movable seat 25 of the present invention is open for the material 34 blown up in the material drawer 9 to pass through. The material 34 is blown into the accommodating space 28 of the movable seat 25 until it is adsorbed by the left flip device 4 or the right flip device 5 .

[0039] The side wall of the accommodation space 28 of the movable seat 25 of the present invention is provided with a plurality of side blowing holes 27. When the side blowing holes 27 ventilate the accommodation space 28, the unabsorbed or unstable adsorbed materials 34 can be blown down from the left flip device 4 or the right flip device 5. Figure 3 In the process, the material 34 deviating from the material adsorption air hole 16 will be blown back into the material drawer 9.

[0040] Furthermore, the upper end surface of the movable seat 25 of the present invention can also adopt an open structure, and a transparent acrylic plate can be installed on the upper end surface of the movable seat 25. When the left flip device 4 or the right flip device 5 adsorbs the material, the left flip device 4 or the right flip device 5 flips so that the vacuum adsorption plane 15 adsorbed to the material faces upward, making it convenient for the operator to observe the vacuum adsorption plane 15.

[0041] Furthermore, an outer cylindrical stopper 18 is formed in the middle of the rotating shaft 12 of the left flip device 4, and a blowing guide groove 19 is formed between the outer cylindrical stopper 18 and the adsorption section 13. When air is blown through the side blowing holes 27 of the movable seat 25, the blowing guide groove 19 can more quickly blow off the material 34 adsorbed on the edge of the vacuum adsorption plane 15, thereby avoiding the movable component 8 from getting stuck in the workpiece fitting gap during movement and causing jamming.

[0042] The mobile assembly 8 of the present invention is connected to the horizontal push-pull cylinder 10, and the horizontal push-pull cylinder 10 is used to drive the mobile assembly 8. A mobile guide rod 11 is horizontally installed between the left bracket 2 and the right bracket 3, and the mobile seat 25 is penetrated on the mobile guide rod 11, and the mobile seat 25 moves along the mobile guide rod 11.

[0043] A material collecting box 30 is provided between the left bracket 2 and the right bracket 3 of the present invention, and the moving assembly 8 is movably located above the material collecting box 30 , and the material collecting box 30 can collect fallen materials.

[0044] like Figure 1 , Figure 2 In the first embodiment of the present invention, the gears of the gear segments 17 of the left flip device 4 and the right flip device 5 are driven to rotate by a synchronous belt, and the synchronous belt is driven by a left motor 6 and a right motor 7 respectively. The left motor 6 and the right motor 7 are respectively installed on the outside of the left bracket 2 and the right bracket 3.

[0045] like Figure 6 In the second embodiment of the present invention, different from the first embodiment, the left flipping device 4 and the right flipping device 5 are flipped by gear rack meshing drive. Specifically, the lifting cylinder 31 is vertically installed on the outside of the left bracket 2 and the right bracket 3, and its telescopic rod is connected to the rack 33. The rack 33 is vertically located on the side of the flipping device 4 and meshes with the gear segment 17. The lifting cylinder 31 drives the rack 33 to move up and down, thereby driving the gear segment 17 to rotate, so that the flipping device 4 is flipped.

[0046] Furthermore, the rack 33 is passed through the vertical guide rod, and the vertical guide rod is mounted on the rack mounting seat 32, and the rack mounting seat 32 is fixed to the left bracket 2 and the right bracket 3 respectively.

[0047] The gas path connection structure of the material adsorption air hole 16, the bottom blowing air hole 22, and the side blowing air hole 27 of the present invention will not be described in detail here.

[0048] The present invention realizes precise loading of materials through a blowing system and a vacuum system. First, the material 34 (such as a shading sheet) is placed in the material slot 21 of the material drawer 9, and the bottom blowing holes 22 blow up the material 34. At the same time, the blown material 34 is firmly adsorbed on the vacuum adsorption plane 15 of the left flip device 4 by the vacuumed material adsorption holes 16, thereby completing the material removal.

[0049] The side blowing holes 27 blow the loosely adsorbed materials 34 back into the material slot 21 of the material drawer 9 .

[0050] The left flip device 4 for adsorbing the material 34 makes the vacuum adsorption plane 15 with the material 34 face upward, and the moving assembly 8 moves to the position of the right flip device 5. At this time, the left flip device 4 waits for the external manipulator to take the material, and the right flip device 5 adsorbs the material. Such an automated production process design greatly improves production efficiency.

[0051] Furthermore, the following method is also possible: the moving component 8 is fixed on the workbench 1, and the left flipping device 4 can be flipped and moved horizontally into the accommodating space of the moving component 8 to realize the feeding of materials, which will not be elaborated here.

[0052] The present invention can realize the whole-line feeding of light and small materials in the assembly of optical lenses, such as annular gaskets with an outer diameter of 8 mm, an inner diameter of 5 mm and a thickness of 0.01 mm.
