Description

Technical Field

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

[0002] Optical glass is a kind of glass material specially used for manufacturing optical elements (such as lenses, prisms, mirrors, etc.). It has high transparency, excellent optical properties, stable physical and chemical characteristics, and specific characteristics that can meet the requirements of different optical applications. Optical glass can change the propagation direction of light and change the relative spectral distribution of ultraviolet, visible or infrared light. It is widely used in manufacturing key components in optical instruments, such as lenses, prisms, mirrors and windows, etc. When processing optical glass, a feeding mechanism is needed to feed the glass to the material inlet of the processing equipment.

[0003] After retrieval, the patent with the publication number CN220788400U discloses a rapid feeding mechanism for optical glass cutting. It stacks and places the glass through a feeding table and a limiting frame, and then pushes the glass from below through a pushing mechanism to ensure the feeding stability. However, there are the following disadvantages when using this mechanism: at the moment when the lowermost glass is pushed out from the bottom of the feeding table, all the stacked glass above will suddenly fall, and there is no buffer in this process, and the glass will collide with each other, which may cause the glass to be damaged and affect the quality of the glass; secondly, the height of the feeding port of this feeding mechanism is fixed and cannot feed materials for processing equipment with different material inlet heights, so further improvement is needed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0023] As Figures 1-4As shown in the figure, it relates to a feeding mechanism for optical flat glass, including a bottom plate 1. Above the bottom plate 1, there is an intermediate plate 2. Above the intermediate plate 2, there is a top plate 3. A material box 4 is fixed on the upper surface of the top plate 3, and the top and one side wall of the material box 4 are open. Inside the material box 4, there is a sliding pallet 5 for placing glass. Outside the material box 4, there is a first lifting component 6 for driving the pallet 5 to move. On the top end of the material box 4 and on the side far from the first lifting component 6, there is a support component 7 installed. On the top end of the material box 4 and on the side close to the support component 7, there is an L-shaped plate 8 fixed, and on the upper surface of the L-shaped plate 8, there is a cylinder 9 fixed. The telescopic end of the bottom of the cylinder 9 is fixedly connected with a material pushing component 10. Between the bottom plate 1 and the intermediate plate 2, there are multiple guiding components 11 connected. In the middle of the upper surface of the bottom plate 1, there is a second lifting component 12 for driving the intermediate plate 2 to move. Between the intermediate plate 2 and the top plate 3, they are fixedly connected by multiple vertical rods. On the upper surface of the bottom plate 1, there is a controller installed.

[0024] On one side of the material box 4 close to the first lifting component 6, there is a vertical strip-shaped opening 41. The first lifting component 6 includes a first motor 61 fixed on the lower surface of the top plate 3 and a sliding plate 63 slidably connected with the strip-shaped opening 41. The driving end of the first motor 61 is fixed with a first lead screw 62. The first lead screw 62 passes through the sliding plate 63 and is threadedly connected with the sliding plate 63. The sliding plate 63 is fixedly connected with the pallet 5.

[0025] By driving the first lead screw 62 to rotate forward or backward by the first motor 61, the sliding plate 63 can be driven to rise and fall along the strip-shaped opening 41, thereby driving the pallet 5 to rise and fall.

[0026] On the inner top wall of the L-shaped plate 8, a laser distance sensor is fixedly installed, and both the laser distance sensor and the first motor 61 are electrically connected to the controller.

[0027] In this embodiment, the laser distance sensor adopts LR-50M, and the controller adopts CJ2M-CPU3. Through the laser distance sensor, the distance from the uppermost glass sheet on the upper surface of the pallet 5 to the laser distance sensor can be monitored in real time. Therefore, every time the controller controls the first motor 61 to drive the pallet 5 to rise, after rising a specified distance, the controller can control the first motor 61 to stop rotating.

[0028] The support component 7 includes a support plate 71 fixed on the top of the material box 4. On the upper surface of the support plate 71, there are several grooves 72 arranged at equal distances, and a roller 73 is rotatably connected inside each groove 72.

[0029] After the material pushing component 10 pushes the glass onto the upper surface of the support plate 71, the roller 73 can reduce the friction between the glass and the support plate 71.

[0030] The material pushing assembly 10 includes a sleeve 101 slidably sleeved on the surface of the telescopic end of the air cylinder 9. A spring 102 is fixedly connected between the inner bottom wall of the sleeve 101 and the telescopic end 9 of the air cylinder. The bottom end of the sleeve 101 is fixedly connected with a U-shaped plate 103. A second motor 105 is fixedly connected to the outer side wall of the U-shaped plate 103. The output shaft of the second motor 105 passes through the U-shaped plate 103 and is fixedly connected with a rubber roller 104. Both the air cylinder 9 and the second motor 105 are electrically connected to the controller.

[0031] After the second motor 105 is controlled by the controller to rotate, the second motor 105 drives the rubber roller 104 to rotate. The rubber roller 104 pushes the uppermost glass sheet towards the upper surface of the support plate 71 through friction.

[0032] The guiding assembly 11 includes a vertical pipe 111 fixed to the upper surface of the bottom plate 1. A guide rod 112 is slidably connected inside the top end of the vertical pipe 111. The top end of the guide rod 112 is fixedly connected to the lower surface of the middle plate 2.

[0033] The guide rod 112 moves along the vertical pipe 111, which can provide stable guidance for the lifting of the middle plate 2.

[0034] The second lifting assembly 12 includes a third motor 121 fixed to the upper surface of the bottom plate 1. The output end of the third motor 121 is fixedly connected with a second lead screw 122. The second lead screw 122 passes through the middle plate 2 and is threadedly connected to the middle plate 2. The third motor 121 is electrically connected to the controller.

[0035] By driving the second lead screw 122 to rotate forward or backward through the third motor 121, the second lead screw 122 can drive the middle plate 2 to lift, so as to adjust the height of the support plate 71 to adapt to the feeding of equipment with different feeding port heights.

[0036] Working principle: Stacked glass sheets are placed on the upper surface of the pallet 5. At this time, the laser distance sensor detects the distance from the uppermost glass to itself, and then feeds the information back to the controller. Then the controller controls the first motor 61 to drive the pallet 5 to rise in the material box 4 until the distance from the uppermost glass sheet to the laser distance sensor reaches the set value. At this time, the uppermost glass just exceeds the upper surface of the support plate 71. Then the controller controls the air cylinder 9 to extend and drive the material pushing assembly 10 to descend. When the rubber roller 104 contacts the glass surface, the second motor 105 is started. The second motor 105 drives the rubber roller 104 to rotate. Under the action of friction, the rubber roller 104 pushes the glass towards the surface of the support plate 71, thus realizing feeding. After feeding, the air cylinder 9 drives the material pushing assembly 10 to reset. Then the controller controls the first motor 61 to drive the pallet 5 to continue to rise, and prepares for the next feeding.
