Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing technology, and in particular to a feeding device. Background Technology

[0002] Before delivery, finished optical lenses need to undergo an appearance inspection to determine if there are any cracks, fissures, or scratches on their surface. Existing optical lens inspection devices (such as the small optical lens inspection device disclosed in application number 202121470941.3) cannot achieve self-feeding of optical lenses during the appearance inspection process. The optical lenses to be inspected must be manually placed sequentially on a first conveyor belt, which then transports them to an optical microscope. Workers then use the microscope to inspect the appearance of the optical lenses. This manual lens placement method increases labor costs. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this 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 this utility model and are not intended to limit this utility model.

[0024] This utility model provides a feeding device, the structure of which is as follows: Figure 1 - Figure 3As shown, the device includes a hopper 100, a transfer mechanism 200, and a pusher mechanism 300. The hopper 100 has a material cavity 110 with openings at both the top and bottom, where multiple lenses are stacked from bottom to top. The transfer mechanism 200 is located at the bottom of the material cavity 110 and can move horizontally back and forth to receive the bottommost single lens in the material cavity 110 and transfer it outside the material cavity 110. The pusher mechanism 300 is located outside the material cavity 110 and is used to push the lens on the transfer mechanism 200 onto a first conveyor belt.

[0025] In use, multiple lenses are stacked from bottom to top in the material cavity 110. By manipulating the transfer mechanism 200, the transfer mechanism 200 can move horizontally back and forth. The transfer mechanism 200 can receive the bottom single lens in the material cavity 110 and transfer the bottom single lens to the outside of the material cavity 110. Then, by manipulating the push mechanism 300, the push mechanism 300 can push the lens on the transfer mechanism 200 onto the first conveyor belt, thereby realizing the self-feeding of lenses. The optical lenses are then transported to the optical microscope by the first conveyor belt. Workers use the optical microscope to inspect the appearance of the optical lenses. This feeding device can sequentially place the optical lenses to be inspected onto the first conveyor belt, reducing labor costs.

[0026] As a preferred embodiment, please refer to Figure 1 and Figure 2 The hopper 100 has a discharge port 120 and a through port 130 respectively on its two opposite side walls. The discharge port 120 and the through port 130 are both connected to the material cavity 110. The material transfer mechanism 200 slides through the discharge port 120 and the through port 130, so that the material transfer mechanism 200 receives the bottom single lens in the material cavity 110 during the sliding process of sliding through the discharge port 120 and the through port 130, and transfers the bottom single lens along the discharge port 120 to the outside of the material cavity 110.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3 The material transfer mechanism 200 has a receiving groove 210, the top and one side wall of the receiving groove 210 are open, the receiving groove 210 is used to accommodate the bottom layer of lens, when the receiving groove 210 is located in the material cavity 110, the bottom layer of single lens falls into the receiving groove 210, the material transfer mechanism 200 moves horizontally outward, and can transfer the bottom layer of single lens to the outside of the material cavity 110.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 2 The material transfer mechanism 200 includes a material transfer platform 220 and a telescopic drive component 230. The material transfer platform 220 slides through the discharge port 120 and the through port 130. The material transfer platform 220 has a receiving groove 210. The output end of the telescopic drive component 230 is connected to the material transfer platform 220 and is used to drive the material transfer platform 220 to move horizontally back and forth, so that the receiving groove 210 alternately reaches the inside or outside of the material cavity 110. By operating the telescopic drive component 230, the material transfer mechanism can be driven. The platform 220 moves horizontally back and forth, causing the receiving groove 210 to alternately reach the inside or outside of the material cavity 110. When the receiving groove 210 is inside the material cavity 110, the bottom layer of a single lens falls into the receiving groove 210. When the receiving groove 210 is outside the material cavity 110, the bottom layer of a single lens can be moved outside the material cavity 110. The telescopic drive 230 can be directly connected to the material transfer platform 220 by selecting a suitable type of cylinder, or it can be connected to the material transfer platform 220 by using a gear set, pulley set or other transmission methods.

[0029] As a preferred embodiment, please refer to Figure 2 The depth of the receiving groove 210 is less than the thickness of the lens, which can prevent the lens of the upper layer from entering the receiving groove 210.

[0030] As a preferred embodiment, please refer to Figure 2 The distance between the top surface of the lens in the receiving groove 210 and the top surface of the discharge port 120 is less than the thickness of a single lens, and the distance between the top surface of the transfer platform 220 and the top surface of the discharge port 120 is less than the thickness of a single lens, which can prevent the lens of the upper layer from being moved out of the discharge port 120 along with the lens of the bottom layer.

[0031] As a preferred embodiment, please refer to Figure 3 and Figure 4The pushing mechanism 300 includes an ear seat 310, a pushing rod 320, a rubber pad 330, and an elastic element 340. The ear seat 310 is fixedly connected to the outer wall of the hopper 100. The upper end of the pushing rod 320 is hinged to the ear seat 310. The rubber pad 330 is fixedly connected to the bottom surface of the pushing rod 320. One end of the elastic element 340 is connected to the outer wall of the hopper 100, and the other end of the elastic element 340 is connected to the pushing rod 320. The rod 320 is connected to keep the push rod 320 in a vertical position. When the push rod 320 is in a vertical position, the bottom surface of the rubber pad 330 is flush with the top surface of the transfer platform 220. After the bottom layer of lenses enters the receiving groove 210, the telescopic drive 230 drives the transfer platform 220 to move outward, causing the receiving groove 210 to move out of the material cavity 110 and pulling the bottom layer of lenses out of the material cavity 110. During the removal of the receiving groove 210, the push rod 320 is pushed to rotate away from the hopper 100. The elastic element 340 is stretched and accumulates tensile elastic potential energy until the lens is completely removed from the material cavity 110. The elastic element 340 then releases the tensile elastic potential energy and drives the push rod 320 to rotate closer to the hopper 100 until the push rod 320 is in a vertical state again. The telescopic drive 230 then drives the transfer platform 220 to move inward, so that the receiving groove 210 enters the material cavity 110. During the movement of the receiving groove 210 inward, since the bottom surface of the rubber pad 330 is flush with the top surface of the transfer platform 220 when the push rod 320 is in a vertical state, the rubber pad 330 pushes the lens in the receiving groove 210 out of the receiving groove 210, and the lens falls onto the first conveyor belt.

[0032] As a preferred embodiment, please refer to Figure 2 The push rod 320 has an L-shaped structure. The end of the short rod of the push rod 320 is hinged to the ear seat 310 via a pin. The rubber pad 330 is fixedly connected to the bottom surface of the long rod of the push rod 320. The other end of the elastic member 340 is connected to the long rod of the push rod 320 so that the long rod of the push rod 320 is in a vertical state. The structure of the push rod 320 makes it easy for the rubber pad 330 to not deform when the long rod of the push rod changes state, thus facilitating the change of state of the long rod of the push rod 320.

[0033] In a preferred embodiment, the elastic element 340 is a spring, which can accumulate tensile elastic potential energy when subjected to a pushing force, and can release the tensile elastic potential energy when the pushing force disappears.

[0034] As a preferred embodiment, please refer to Figure 3The pushing mechanism 300 further includes a limiting block 350, which is fixedly connected to the outer wall of the hopper 100. When the long rod of the pushing rod 320 is in a vertical state, the long rod of the pushing rod 320 abuts against the limiting block 350. The limiting block 350 can limit the pushing rod 320 to prevent it from continuing to rotate towards the hopper 100 after the long rod of the pushing rod 320 is in a vertical state.

[0035] As a preferred embodiment, please refer to Figure 1 and Figure 2 The feeding device further includes a support platform 400. The bottom of the hopper 100 is fixedly connected to the support platform 400, and the bottom of the transfer platform 220 is slidably connected to the support platform 400. The support platform 400 can provide support for the hopper 100 and the transfer platform 220.

[0036] As a preferred embodiment, please refer to Figure 2 The support platform 400 includes a platform body 410 and two baffles 420. The two baffles 420 are disposed opposite to each other on both sides of the platform body 410. The transfer platform 220 is located between the two baffles 420. The baffles 420 can block the lenses falling on the support platform 400 and prevent the lenses on the support platform 400 from falling off the side of the support platform 400.

[0037] As a preferred embodiment, please refer to Figure 2 The platform 410 has a horizontal section 411 and an inclined section 412. The high end of the inclined section 412 is fixedly connected to the horizontal section 411, and the low end of the inclined section 412 is connected to the inlet end of the first conveyor belt. The bottom of the hopper 100 is fixedly connected to the horizontal section 411, and the bottom of the transfer platform 220 is slidably connected to the horizontal section 411. The rubber pad 330 pushes the lens in the receiving groove 210 out of the receiving groove 210, and the lens falls on the horizontal section 411. When the telescopic drive member 230 drives the transfer platform 220 to move outward again, the transfer platform 220 will push the lens that has fallen on the horizontal section 411 onto the inclined section 412, and the lens slides down the inclined section 412 onto the first conveyor belt.

[0038] To better understand this utility model, the following is combined with... Figure 1 - Figure 4 The working principle of the technical solution of this utility model will be described in detail below:

[0039] In use, multiple lenses are stacked from bottom to top in the material cavity 110. When the bottommost lens enters the receiving slot 210, the telescopic drive 230 drives the transfer platform 220 to move outward, causing the receiving slot 210 to move out of the material cavity 110, and pulling the bottommost lens out of the material cavity 110. During the movement of the receiving slot 210 outward, it pushes the long rod of the push rod 320 to rotate away from the hopper 100. The elastic element 340 stretches and accumulates tensile elastic potential energy until the lens is completely removed from the material cavity 110. The elastic element 340 then releases the tensile elastic potential energy and drives the long rod of the push rod 320 to rotate closer to the hopper 100 until the long rod of the push rod 320 is vertical again. The telescopic drive 230 then drives the transfer platform 220 to move inward, causing the receiving slot 210 to move out of the material cavity 110. When the lens enters the material cavity 110 and moves into the receiving groove 210, the bottom surface of the rubber pad 330 is flush with the top surface of the transfer platform 220 when the long rod of the push rod 320 is in a vertical state. Therefore, the rubber pad 330 will push the lens in the receiving groove 210 out of the receiving groove 210, and the lens will fall on the horizontal section 411. When the telescopic drive member 230 drives the transfer platform 220 to move outward again, the transfer platform 220 will push the lens that has fallen on the horizontal section 411 onto the inclined section 412. The lens slides down the inclined section 412 onto the first conveyor belt, thereby realizing the self-feeding of the lens. Then, the optical lens is transported to the optical microscope by the first conveyor belt. The worker uses the optical microscope to inspect the appearance of the optical lens. This feeding device can put the optical lens to be inspected onto the first conveyor belt in sequence, reducing labor costs.

[0040] The feeding device provided by this utility model has the following beneficial effects:

[0041] (1) When the bottom layer of lens enters the receiving groove 210, the telescopic drive 230 drives the transfer platform 220 to move outward, causing the receiving groove 210 to move out of the material cavity 110, and driving the bottom layer of lens to move out of the material cavity 110. During the process of the receiving groove 210 moving out, it will push the push rod 320 to rotate away from the hopper 100, the elastic element 340 will stretch and accumulate tensile elastic potential energy until the lens is completely moved out of the material cavity 110, and the elastic element 340 will release the tensile elastic potential energy. The push rod 320 is driven to rotate towards the hopper 100 until it is vertical again. Then the telescopic drive 230 drives the transfer platform 220 to move inward, so that the receiving groove 210 enters the material cavity 110. During the process of the receiving groove 210 moving in, since the bottom surface of the rubber pad 330 is flush with the top surface of the transfer platform 220 when the push rod 320 is vertical, the rubber pad 330 will push the lens in the receiving groove 210 to move out of the receiving groove 210.

[0042] (2) When the telescopic drive 230 drives the transfer platform 220 to move outward again, the transfer platform 220 will push the lens that falls on the horizontal section 411 onto the inclined section 412, and the lens will slide down the inclined section 412 onto the first conveyor belt.

[0043] (3) This feeding device can sequentially place the optical lenses to be tested onto the first conveyor belt, reducing labor costs.
