Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, and more specifically, it relates to an automatic loading and unloading structure for a lens grinding machine. Background Technology

[0002] In the eyewear manufacturing industry and the field of optical lens production, lens grinding is a crucial step. With the continuous growth in market demand for lenses and the increasing requirements for product quality, the efficiency and precision of lens grinding have become important factors for companies to enhance their competitiveness.

[0003] Traditional lens grinding machines rely heavily on manual operation for loading and unloading. Workers manually place lenses onto the machine's clamping device for loading, and then manually remove them after processing to unload. With the widespread application of automation technology in industrial production, new solutions have been found for the loading and unloading process in lens grinding machines. Automated loading and unloading structures can automatically transport, clamp, and release lenses, reducing manual intervention and improving production efficiency and product quality. However, some existing automated loading and unloading structures in lens grinding machines typically use a robotic arm to transport lenses to the upper surface of the lower clamping block. However, due to the small distance between the upper and lower clamping blocks, the distance between them needs to be adjusted when the robotic arm moves the lens to the upper surface of the lower clamping block. This adjustment of the distance between the upper and lower clamping blocks creates inconvenience for lens loading. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic loading and unloading structure for a lens grinding machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic loading and unloading structure for a lens grinding machine includes a grinding machine body, wherein an upper clamping block and a lower clamping block are disposed inside the grinding machine body, and further includes:

[0007] The moving block, wherein the lower clamping block is rotatably connected to the top of the moving block, and the moving block moves relatively vertically inside the grinding machine body to realize the vertical movement of the lower clamping block inside the grinding machine body;

[0008] Symmetrically arranged conveyor blocks move horizontally relative to the grinding machine body to transport the lens carried on the upper surface of the conveyor blocks to between the upper clamping block and the lower clamping block. The lower clamping block moves upward inside the grinding machine body to lift the lens carried on the upper surface of the conveyor blocks until the lens is clamped between the lower and upper clamping blocks to achieve loading. After the lens clamped between the lower and upper clamping blocks is ground, the lower clamping block moves downward until the lens is located on the upper surface of the conveyor blocks to achieve unloading.

[0009] A gap is reserved between the two material transport blocks.

[0010] Preferably, a transparent plate is fixedly connected to the side wall of the grinding machine body.

[0011] Preferably, it also includes a conveyor belt that is movable relative to the grinding machine body, and the conveyor belt and the material block are fixedly connected by a connecting rod.

[0012] Preferably, the grinding machine body has a through hole for the conveyor belt to pass through; a support plate for supporting the upper conveyor belt is fixedly connected to the grinding machine body.

[0013] Preferably, a fixing plate is fixedly connected to the outer side wall of the grinding machine body, a rotating rod is rotatably connected to the side wall of the fixing plate, a rotating wheel is fixedly connected to the rotating rod, and the conveyor belt is sleeved between the two rotating wheels.

[0014] Preferably, a first drive motor is fixedly connected to the side wall of one of the fixed plates, and the drive shaft of the first drive motor is fixedly connected to one of the rotating rods.

[0015] Preferably, a baffle is fixedly connected to the upper edge of the material conveying block.

[0016] Preferably, a second drive motor is fixedly connected inside the grinding machine body, and a rotating rod is fixedly connected to the drive shaft of the second drive motor, and the rotating rod is fixedly connected to the upper clamping block.

[0017] Preferably, an electric telescopic rod is fixedly connected inside the grinding machine body, and the telescopic end of the electric telescopic rod is fixedly connected to the lower clamping block.

[0018] Preferably, it also includes a loading box fixedly connected to the outer side wall of the grinding machine body, wherein a pusher block is fixedly connected to the side wall of the loading box, and the position and spacing of the pusher block correspond to each other.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this invention, the automatic horizontal movement of the material transport block is achieved through the cooperation of the conveyor belt and the connecting rod. During the movement of the material transport block, the lens is accurately transported between the upper clamping block and the lower clamping block to complete the loading process. During the unloading process, the conveyor belt moves and the material transport block moves through the connecting rod. During the movement of the material transport block, the ground lens is transported to the outside of the grinding machine body. The entire process does not require manual handling of the lens, which greatly saves manpower and time and improves production efficiency. This invention can quickly send the lens into the grinding position and send the processed lens out, and can realize continuous grinding of the lens. Compared with the traditional manual loading and unloading method, it greatly shortens the auxiliary time for processing a single lens.

[0021] This application enables the lower clamping block to move automatically up and down. During loading, the lower clamping block moves upward to lift the lens on the conveyor block, and the lower clamping block cooperates with the upper clamping block to clamp the lens. During unloading, the lower clamping block moves downward to place the lens on the conveyor block. This automatic clamping and releasing method improves the efficiency of loading and unloading. Furthermore, this application eliminates the need to adjust the distance between the upper and lower clamping blocks during the lens loading and unloading process, bringing convenience to lens loading.

[0026] Example 1 further illustrates the automatic loading and unloading structure of a lens grinding machine proposed in this utility model.

[0027] Reference Figures 1 to 3An automatic loading and unloading structure for a lens grinding machine includes a grinding machine body 100, with an upper clamping block 401 and a lower clamping block 402 internally arranged, and further includes:

[0028] The moving block 300 and the lower clamping block 402 are rotatably connected to the top of the moving block 300, and the moving block 300 moves relatively vertically inside the grinding machine body 100 to realize the vertical movement of the lower clamping block 402 inside the grinding machine body 100.

[0029] The symmetrically arranged conveyor blocks 200 move horizontally relative to the grinding machine body 100 to transport the lens carried on the upper surface of the conveyor blocks 200 to between the upper clamping block 401 and the lower clamping block 402. The lower clamping block 402 moves upward inside the grinding machine body 100 to lift the lens carried on the upper surface of the conveyor blocks 200 until the lens is clamped between the lower clamping block 402 and the upper clamping block 401 to achieve loading. After the lens clamped between the lower clamping block 402 and the upper clamping block 401 is ground, the lower clamping block 402 moves downward until the lens is located on the upper surface of the conveyor blocks 200 to achieve unloading.

[0030] A gap 201 is reserved between the two material conveying blocks 200, which allows the lower clamping block 402 or the moving block 300 to pass through.

[0031] Reference Figure 1 A transparent plate 102 is fixedly connected to the side wall of the grinding machine body 100. The transparent plate 102 is made of transparent material, which makes it easy to observe the processing inside the grinding machine body 100.

[0032] Reference Figure 1 It also includes a conveyor belt 500 that is movable relative to the grinding machine body 100. The conveyor belt 500 and the material transport block 200 are fixedly connected by a connecting rod 600. Since the material transport block 200 is fixedly connected to the conveyor belt 500 by the connecting rod 600 and the conveyor belt 500 moves relative to the grinding machine body 100, the material transport block 200 moves through the connecting rod 600 during the movement of the conveyor belt 500. Since the lens is placed on the upper surface of the two material transport blocks 200, the lens is loaded and unloaded during the movement of the material transport blocks 200.

[0033] Reference Figure 2 The grinding machine body 100 has a through hole 101 for the conveyor belt 500 to pass through; a support plate 504 for supporting the upper conveyor belt 500 is fixedly connected to the grinding machine body 100. The through hole 101 makes it easy for both ends of the conveyor belt 500 to be located outside the grinding machine body 100, and the middle part of the conveyor belt 500 to be located inside the grinding machine body 100; at the same time, the support plate 504 provides support for the upper conveyor belt 500.

[0034] Reference Figure 1 A fixed plate 700 is fixedly connected to the outer side wall of the grinding machine body 100. A rotating rod 501 is rotatably connected to the side wall of the fixed plate 700. A rotating wheel 502 is fixedly connected to the rotating rod 501. The conveyor belt 500 is sleeved between the two rotating wheels 502.

[0035] Reference Figure 1 One of the fixed plates 700 has a first drive motor 503 fixedly connected to its side wall, and the drive shaft of the first drive motor 503 is fixedly connected to one of the rotating rods 501.

[0036] The first drive motor 503 operates to rotate one of the rotating rods 501, which in turn rotates the rotating wheel 502, and the rotating wheel 502 moves the conveyor belt 500.

[0037] Reference Figure 3 A baffle 202 is fixedly connected to the upper edge of the conveying block 200. When the lens is placed on the upper surface of the two conveying blocks 200, the baffle 202 is fixedly connected to the upper edge of the conveying block 200, thereby preventing the lens from sliding off the side of the conveying block 200.

[0038] Reference Figure 3 The grinding machine body 100 is internally fixedly connected to a second drive motor 403, and a rotating rod 404 is fixedly connected to the drive shaft of the second drive motor 403. The rotating rod 404 is fixedly connected to the upper clamping block 401.

[0039] Reference Figure 3 An electric telescopic rod 405 is fixedly connected inside the grinding machine body 100, and the telescopic end of the electric telescopic rod 405 is fixedly connected to the lower clamping block 402.

[0040] As the two conveyor blocks 200 transport the lens between the upper clamping block 401 and the lower clamping block 402, the electric telescopic rod 405 operates to move the lower clamping block 402 upward within the gap 201. During the upward movement of the lower clamping block 402, it lifts the lens carried between the two conveyor blocks 200 upward until the lens is clamped by the cooperation of the upper clamping block 401 and the lower clamping block 402. Afterward, the two conveyor blocks 200 continue to move away from the vicinity of the upper clamping block 401 and the lower clamping block 402, and the second drive motor 403 operates to achieve... Rotating rod 404 rotates, causing upper clamping block 401 to rotate. Since lower clamping block 402 is rotatably connected to the top of moving block 300, upper clamping block 401 and lower clamping block 402 drive the lens to rotate. During the rotation of the lens, it is convenient to perform grinding processing on the lens through the grinding mechanism of grinding machine body 100. Since the grinding mechanism of grinding machine body 100 includes structures such as grinding wheels, and the grinding mechanism of grinding machine body 100 is the prior art in this application, the grinding mechanism of grinding machine body 100 is not shown in the accompanying drawings.

[0041] Working principle: When the material conveying block 200 is located outside the grinding machine body 100, the operator places the two ends of the lens to be ground on the upper surface of the two material conveying blocks 200 respectively. The first drive motor 503 works to make one of the rotating rods 501 rotate. During the rotation of the rotating rod 501, the rotating wheel 502 rotates. During the rotation of the rotating wheel 502, the conveyor belt 500 moves. During the movement of the conveyor belt 500, the material conveying block 200 moves through the connecting rod 600. When the material conveying block 200 carrying the lens moves between the upper clamping block 401 and the lower clamping block 402, the first drive motor 503 stops working. The electric telescopic rod 405 works to make the lower clamping block 402 move upward within the gap 201. During the upward movement of the lower clamping block 402, the lens carried between the two material conveying blocks 200 is lifted upward until the lens is clamped by the cooperation of the upper clamping block 401 and the lower clamping block 402, thereby realizing the loading process of the lens.

[0042] The first drive motor 503 operates to rotate one of the rotating rods 501. During the rotation of the rotating rod 501, the rotating wheel 502 rotates, and during the rotation of the rotating wheel 502, the conveyor belt 500 moves. During the movement of the conveyor belt 500, the material transport block 200 moves through the connecting rod 600, thereby moving the two material transport blocks 200 away from the vicinity of the upper clamping block 401 and the lower clamping block 402. The second drive motor 403 operates to rotate the rotating rod 404. When the rotating rod 404 rotates, the upper clamping block 401 rotates. Since the lower clamping block 402 is rotatably connected to the top of the moving block 300, the upper clamping block 401 and the lower clamping block 402 drive the lens to rotate. During the rotation of the lens, it is convenient for the lens to be ground by the grinding mechanism of the grinding machine body 100.

[0043] After the lens is ground, the first drive motor 503 operates to rotate one of the rotating rods 501. During the rotation of the rotating rod 501, the rotating wheel 502 rotates, and during the rotation of the rotating wheel 502, the conveyor belt 500 moves. During the movement of the conveyor belt 500, the material transport block 200 moves through the connecting rod 600, thereby enabling the next set of two material transport blocks 200 to move between the upper clamping block 401 and the lower clamping block 402. The electric telescopic rod 405 operates to move the lower clamping block 402 downward. During the downward movement of the lower clamping block 402, the lens supported at the top of the lower clamping block 402 moves downward until both ends of the lens are located on the upper surface of the two material transport blocks 200. That is, the two material transport blocks 200 support both ends of the lens, thereby realizing the unloading of the lens after grinding.

[0044] The first drive motor 503 operates to rotate one of the rotating rods 501. During the rotation of the rotating rod 501, the rotating wheel 502 rotates. During the rotation of the rotating wheel 502, the conveyor belt 500 moves. During the movement of the conveyor belt 500, the material block 200 moves through the connecting rod 600, thereby moving the lens after grinding to the outside of the grinding machine body 100.

[0045] Example 2

[0046] The following technical features are added based on Embodiment 1:

[0047] Reference Figure 2 It also includes a loading box 800 fixedly connected to the outer side wall of the grinding machine body 100. A pusher block 801 is fixedly connected to the side wall of the loading box 800, and the position of the pusher block 801 corresponds to the spacing 201.

[0048] When the lens after grinding moves to the outside of the grinding machine body 100, the position of the pusher block 801 corresponds to the spacing 201, thereby pushing the lens carried by the two conveyor blocks 200 into the inside of the loading box 800 through the pusher block 801, that is, the lens after grinding is collected inside the loading box 800.

[0049] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
