Description

Technical Field

[0001] The utility model belongs to the technical field of shearing machines, in particular to an automatic shearing machine for lens production with an elastic locking mechanism. Background Art

[0002] With the popularization of photography technology and the increasing demand for high-quality images, the role of optical systems in electronic products is becoming increasingly important. In the process of photography, in order to capture a wider scene, the angle of view of the lens becomes crucial. To meet this demand, most modern lenses are composed of multiple lenses that need to be precisely cut and processed to ensure their optical performance.

[0003] The utility model with Chinese patent application number CN202020726026.5 discloses an automatic cutting machine for wide-angle lens lenses, including a base, and two vertical plates are fixedly installed on the upper surface of the base, and inner grooves are provided on the inner sides of the two vertical plates, and a feeding mechanism for feeding the lenses is arranged between the two inner grooves, and six fixing mechanisms for fixing the lenses for cutting are also arranged inside the feeding mechanism. By starting the rotating motor, the crawler can be driven to rotate on the two round rods, and the lenses can be transported through the circular plates and the upper grooves. After the transmission gear rotates half a circle, the lens can be stopped just below the machine body. At this time, the lens is cut through the machine body, and then when the transmission gear continues to rotate half a circle, the surface of the transmission gear fits with the inner side of the crawler, so that the next lens can be driven for cutting, and then automatic and accurate feeding can be performed, avoiding the need for additional manpower, and effectively improving the convenience of user use.

[0004] The above comparative documents have the following problems:

[0005] In existing shearing machines, lenses are transported by tracks. This design has obvious defects. First, due to the hardness and surface roughness of the tracks, the lenses are easily scratched and damaged during the transmission process, which not only affects the appearance of the lenses, but more importantly, may damage their optical properties. Secondly, when the lenses are placed in a fixing mechanism for cutting, since the fixing mechanism is not equipped with a protective mechanism, the lenses are also at risk of being damaged during the tightening process. Utility Model Content

[0006] The utility model provides an automatic shearing machine for lens production with an elastic locking mechanism, aiming to solve the problem that in the existing shearing machine, the lenses are transported by a crawler belt, and the lenses are easily scratched and damaged during the transmission process; secondly, when the lenses are placed in a fixing mechanism for cutting, the fixing mechanism is not provided with a protective mechanism, so the lenses are also at risk of being damaged during the fastening process.

[0007] The utility model is implemented as follows: an automatic shearing machine for lens production with an elastic locking mechanism, comprising a shearing table; a shearing body arranged above the shearing table; and an adjusting mechanism arranged beside the shearing body; wherein the adjusting mechanism comprises: a wedge block sliding above the shearing table; a receiving block rotating above the wedge block; a plurality of support rods arranged on the outside of the receiving block; a placement plate being arranged on the side of the support rod away from the receiving block; a vertical rod arranged on the placement plate; a limiting plate arranged on the outside of the vertical rod; a threaded hole arranged in the limiting plate, a fastening screw being matched with the thread in the threaded hole, a pressure plate being arranged at one end of the fastening screw passing through the threaded hole; a plurality of return springs arranged on the bottom side of the pressure plate, dampers being arranged in each of the plurality of return springs; and a rubber pad arranged on the bottom side of the plurality of return springs.

[0008] Preferably, the shearing body comprises: a shearing shell arranged above the shearing platform; a longitudinal screw slide arranged in the shearing shell; a connecting plate arranged at one end of the movable end of the longitudinal screw slide extending to the outside of the shearing shell; and a cutting knife arranged on the bottom side of the connecting plate.

[0009] Preferably, a servo motor is arranged in the wedge block, and the output end of the servo motor is fixedly connected to the end key of the receiving block.

[0010] Preferably, a transverse screw slide is provided in the shearing table, and the movable end of the transverse screw slide extends to one side above the shearing table and is fixedly connected to the bottom side of the wedge block.

[0011] Preferably, both the shearing platform and the shearing shell are provided with limiting sliding grooves.

[0012] Preferably, the cross section of the placement plate is circular.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0014] First, the device has a safe fixing and protection mechanism. When the pressure plate descends and contacts the lens surface, the return spring and the damper are compressed, providing a certain elasticity and damping effect for the lens. This design not only ensures that the lens is firmly fixed, but also avoids damage caused by excessive compression, making the pressure of the pressure plate on the lens adjustable. This adaptive adjustment mechanism ensures that the lens is firmly fixed, but also avoids damage to the lens due to excessive compression, so that the device can adapt to a variety of different production needs, thereby improving the versatility and adaptability of the equipment.

[0015] Second: This device has an efficient loading mechanism. When a single lens is cut, the rotational motion of the servo motor can be accurately transmitted to the receiving block to drive the placement block to rotate. This design realizes the automatic replacement and loading of the lens, greatly improving production efficiency. Through the automated replacement process, it reduces manual intervention and operation time, allowing the device to produce continuously and efficiently, which not only improves production efficiency but also reduces the labor intensity of operators.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model provides an automatic shearing machine for lens production with an elastic locking mechanism, such as Figure 1-4 As shown, it includes a shearing platform 1; a shearing body arranged above the shearing platform 1; and an adjusting mechanism arranged beside the shearing body; wherein the adjusting mechanism includes: a wedge block 2 sliding above the shearing platform 1; a receiving block 3 rotating above the wedge block 2; a plurality of support rods 4 arranged on the outside of the receiving block 3; a placement plate 5 is arranged on the side of the support rod 4 away from the receiving block 3; a vertical rod 6 is arranged on the placement plate 5; a limiting plate 7 is arranged on the outside of the vertical rod 6; a threaded hole 8 is arranged in the limiting plate 7, the threaded hole 8 is threaded with a fastening screw 9, and a pressure plate 10 is arranged at one end of the fastening screw 9 passing through the threaded hole 8; a plurality of return springs 11 are arranged on the bottom side of the pressure plate 10, and a damper is arranged in each of the return springs 11; and a rubber pad 12 is arranged on the bottom side of the return springs 11.

[0024] It should be noted that, since the lenses in the existing shearing machines are transported by tracks, the lenses are easily scratched and damaged during the transmission process. Secondly, when the lenses are placed in the fixing mechanism for cutting, since the fixing mechanism is not equipped with a protective mechanism, the lenses are also at risk of being damaged during the tightening process. This solution adopts a safe fixing mechanism, which uses a reset spring 11 and a damper to ensure that the lens is firmly fixed while avoiding damage due to excessive compression. The adaptive adjustment enables the device to adapt to various production needs and improves versatility. In addition, the efficient feeding mechanism accurately transmits rotational motion through the servo motor 17 to realize automatic lens replacement, reduce manual intervention, improve production efficiency, and reduce labor intensity. In summary, this device is both safe and efficient, meets diversified production needs, and improves overall production efficiency.

[0025] Specifically, in this embodiment, the scheme mainly includes a shearing table 1, a shearing body and an adjusting mechanism; first, the lens to be sheared is placed on a special placement plate 5; by rotating the fastening screw 9, the pressure plate 10 is gradually lowered, and during the lowering process of the pressure plate 10, the return spring 11 and the damper on the bottom side are compressed, and the rubber pad 12 is in contact with the surface of the lens; due to the presence of the return spring 11 and the damper, the pressure of the pressure plate 10 on the lens has a certain elasticity and damping effect; this design not only ensures that the lens is firmly fixed, but also avoids damage caused by excessive compression; when the lens is firmly fixed, the lens moves to the bottom of the cutting knife 16 for shearing operation. During the shearing process, since the lens is fixed very stably, the shearing quality and accuracy can be guaranteed;

[0026] After a single lens is cut, the receiving block 3 will rotate to rotate the lens on another placement block to below the cutting knife 16 for processing. In this way, the shearing machine can continuously perform shearing operations on multiple lenses, greatly improving production efficiency.

[0027] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the shearing body includes: a shearing shell 13 arranged above the shearing platform 1; a longitudinal screw slide 14 arranged in the shearing shell 13; a connecting plate 15 is arranged at one end of the longitudinal screw slide 14 extending from the movable end to the outside of the shearing shell 13; and a cutting knife 16 is arranged on the bottom side of the connecting plate 15.

[0028] In this embodiment, the motor of the longitudinal screw slide 14 is started to drive its moving end to drive the connecting plate 15 to move in the vertical direction. The movement of the connecting plate 15 drives the cutting knife 16 to adjust its height synchronously. This height adjustment function enables the cutting knife 16 to be accurately positioned at the required cutting position to ensure the accuracy and precision of the cutting operation. The cutting knife 16 adopts a sharp blade combination to ensure that the lens material can be cut quickly and cleanly during the cutting process, reduce the resistance during cutting, and improve the cutting efficiency.

[0029] In a further preferred embodiment of the present invention, Figure 2 As shown, a servo motor 17 is provided in the wedge block 2 , and the output end of the servo motor 17 is fixedly connected to the end key of the receiving block 3 .

[0030] In this embodiment, the rotational motion of the servo motor 17 can be accurately transmitted to the receiving block 3, thereby driving the receiving block 3 to rotate. The rotation of the receiving block 3 will drive the placement block and the lens to move together, thereby rotating the lens to be cut to the bottom of the cutting knife for processing. This design not only realizes the automatic replacement of the lens, but also greatly improves the production efficiency.

[0031] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a transverse screw slide 18 is provided in the shearing platform 1 , and the movable end of the transverse screw slide 18 extends to one side above the shearing platform 1 and is fixedly connected to the bottom side of the wedge block 2 .

[0032] In this embodiment, the motor of the transverse screw slide 18 is started so that its moving end drives the wedge block 2 to move horizontally, providing the adjustment mechanism with precise movement and positioning capabilities in the horizontal direction, ensuring the stability and accuracy of the lens during the cutting process, thereby improving the efficiency and quality of lens production.

[0033] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the shearing platform 1 and the shearing shell 13 are both provided with limiting sliding grooves 19 .

[0034] In this embodiment, the limiting slide groove 19 can provide support and guidance for the moving parts. During the movement of the moving parts, the limiting slide groove 19 can serve as part of its supporting structure, bearing part of the load and providing stable guidance, which helps to reduce deformation and wear of the moving parts and extend their service life.

[0035] In a further preferred embodiment of the present invention, Figure 1 As shown, the cross section of the placement plate 5 is circular.

[0036] In this embodiment, the circular cross-section makes the contact surface between the placement plate 5 and the lens more uniform, reduces stress concentration at the contact point, and thus reduces the risk of damage to the lens or the placement plate 5 due to excessive local pressure.

[0037] Working principle: The motor of the transverse screw slide 18 is started so that its moving end drives the wedge block 2 to move horizontally, providing the adjustment mechanism with precise movement and positioning capabilities in the horizontal direction, ensuring the stability and accuracy of the lens during the shearing process, thereby improving the efficiency and quality of lens production;

[0038] First, place the lens to be cut on the special placement plate 5; turn the fastening screw 9 to gradually lower the pressure plate 10. During the lowering process of the pressure plate 10, the return spring 11 and the damper on the bottom are compressed, and the rubber pad 12 contacts the surface of the lens. Due to the presence of the return spring 11 and the damper, the pressure of the pressure plate 10 on the lens has a certain elasticity and damping effect. This design ensures that the lens is firmly fixed and avoids damage caused by excessive compression.

[0039] When the lens is firmly fixed, the motor of the longitudinal screw slide 14 starts to drive its moving end to drive the connecting plate 15 to move in the vertical direction. The movement of the connecting plate 15 drives the cutting knife 16 to adjust its height synchronously. This height adjustment function enables the cutting knife 16 to accurately locate the required cutting position, ensuring the accuracy and precision of the cutting operation while meeting the cutting requirements of different lenses. The cutting knife 16 adopts a sharp blade combination to ensure that the lens material can be cut quickly and cleanly during the cutting process, reducing the resistance during cutting and improving the cutting efficiency.

[0040] After a single lens is cut, the rotational motion of the servo motor 17 can be accurately transmitted to the receiving block 3, thereby driving the receiving block 3 to rotate. The rotation of the receiving block 3 will drive the placement block and the lens to move together, thereby rotating the lens to be cut to the bottom of the cutting knife 16 for processing. This design not only realizes the automatic replacement of the lens, but also greatly improves the production efficiency.

[0041] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
