Description

TECHNICAL FIELD

[0001] The application relates to a bending device for heating a heating wire of a lens, and belongs to the technical field of lens processing. BACKGROUND

[0002] A lens refers to an optical component of a movie camera or a projector for generating an image, and the lens can be classified in various ways, such as by focal length, by aperture, and by lens extension adjustment. According to the focal length, the lens can be classified into fixed focal length type, zoom type, automatic aperture type, or manual aperture type. According to the focal length number, the lens can be classified into standard lens, wide-angle lens, and telephoto lens. According to the aperture, the lens can be classified into fixed aperture type, manual aperture type, and automatic aperture type. According to the lens extension adjustment method, the lens can be classified into electric zoom lens and manual zoom lens.

[0003] Taking an interchangeable lens for a 35mm single-lens reflex camera as an example, a standard lens generally refers to a photographic lens with a focal length of 40 to 55 mm, which is the most basic type of all lenses. The standard lens gives a visual effect of recording reality, so its use frequency is relatively high in actual shooting. However, on the other hand, since the picture effect of the standard lens is very similar to the human visual effect, the picture effect obtained by using the standard lens is very ordinary, and even can be said to be very "flat", and it is difficult to obtain the artistic effect of rendering the picture as in the wide-angle lens or the telephoto lens.

[0004] The lens is an optical device composed of lenses. At present, the lens has a heating function, which can eliminate the ice mist generated on the lens surface to improve the shooting clarity. However, it is not easy to effectively operate when installing the heating sheet on the lens, especially when batch processing the heating lens. The heating wire not only needs to be accurately installed on the lens to improve the heat conduction efficiency, but also needs to avoid interference with the picture acquisition. After the heating wire connected with the heating sheet is bent, the fitting effect is poor, it is not easy to effectively fit with the lens subsequently, and when an error occurs, it is easy to affect the shooting picture. Therefore, it is not easy to accurately install and fix the heating sheet, and the processing efficiency of the heating lens is reduced.

[0005] For example, Chinese patent document CN118859444A discloses a heating lens group, which includes an imaging lens group, a heater, and a lens barrel. The imaging lens group includes an inner lens group and an outer lens group. The outer lens group includes at least one outer lens. The heater is used to heat the imaging lens group and includes at least two parts. One of the at least two parts is in direct contact with the imaging lens group. The lens barrel is used to accommodate the other of the at least two parts. The at least two parts of the heater include a non-heat zone and a heat zone of a heating element. In this scheme, the bending of the heating wire requires very professional bending tool machines.

[0006] Also, such as Chinese patent document CN111623313A discloses a motor vehicle lamp assembly comprising a housing, a light source, a light-transmissive lens, a heater member, the heater member being configured to direct thermal radiation emitted from the light source onto the light-transmissive lens to regulate the temperature of the inner surface (20) of the light-transmissive lens.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will understand that this description is exemplary and does not limit the present invention to the scope of the described embodiments.

[0032] like Figures 1-2 As shown in Figures 9 and 10, the bending device for heating the heating wire of the lens in this embodiment of the invention includes: a frame assembly 100, on which a first feeding assembly 300, a clamping assembly 400, and a second feeding assembly 500 for processing the lens assembly 200 are arranged sequentially from right to left; a third feeding assembly 600 is also fixedly installed on the frame assembly 100 and is correspondingly arranged above the lens assembly 200; the frame assembly 100 is composed of a base plate 101, and a material storage mechanism is fixedly installed on the top surface of the base plate 101 and located on one side of the second feeding assembly 500; the lens assembly 200 is composed of a lens barrel 201, a lens group 208, and a screw cap 209. The lens barrel 201 has a through hole 202 for installing the heating module on its edge. The through hole 202 is also provided with a plug 205 and a plug block 207 that fit into each other. The plug 205 and the plug block 207 are both inserted into the through hole 202. The first feeding component 300, the clamping component 400 and the second feeding component 500 are all fixedly installed on the top surface of the base plate 101. The first feeding component 300 is provided with a gripping mechanism for clamping and flipping the lens barrel 201. The lens barrel 201 is set on the clamping component 400. The second feeding component 500 is set between the storage mechanism and the clamping component 400 for feeding the plug 205. The plug 205 is fixedly connected to the heat insulation sheet 204.

[0033] The base plate 101 is provided with a storage mechanism and a guide platform 102 at both ends. There are two guide platforms 102, which are symmetrically arranged on both sides of the base plate 101 for placing the lens barrel 201. The storage mechanism consists of a first placement frame 103 and a second placement frame 104. The base plate 101 is fixedly connected to the first placement frame 103 and the second placement frame 104. The first placement frame 103 is provided with a first pushing device 105 for pushing the heat insulation sheet 204 and the plug 205. The second placement frame 104 is equipped with a second pushing device 106 for conveying the plug block 207. Both the first pushing device 105 and the second pushing device 106 are composed of cylinders with push plates to achieve pushing one by one.

[0034] Furthermore, such as Figures 2-4As shown, in this technical solution, the guide table 102 can be used for the overlap of the lens barrel 201. Before assembly, the gripper 304 on the first feeding component 300 rotates to be flush with the bottom plate 101 below the guide table 102. When the lens barrel 201 is pushed from the guide table 102 to the gripper 304, it is held by the gripper 304 and rotated to realize the feeding of the lens barrel 201. The first placement frame 103 and the second placement frame 104 can be used for the sequential conveying of the plug 205 and the block 207. The plug 205 and the block 207 are pushed sequentially by the first pushing device 105 and the second pushing device 106. The first pushing device 105 and the second pushing device 106 can push the plug 205 and the block 207 to move horizontally through the push plate at the telescopic end of the cylinder, so that the plug 205 corresponds to the second feeding component 500 and the plug 205 corresponds to the second telescopic cylinder 608, realizing convenient and fast feeding.

[0035] The through-hole 202 in the lens barrel 201 is filled with waterproof adhesive. The through-hole 202 is connected to a heating module, which consists of a heating wire 203 located inside the through-hole 202. Both ends of the heating wire 203 are connected to an FPC interface and a heating element with a thermistor, respectively. Multiple lens groups 208 are embedded within the lens barrel 201. The outermost lens is fitted to the heating element. A screw cap 209 is threaded onto one end of the lens barrel 201 and is pressed against the edge of the outermost lens. The diameter of the through-hole 202 is... The width of the heating element is greater than that of the heating element so that the heating module can pass through the through hole 202. A truncated cone-shaped plug 205 is provided inside one side of the through hole 202. The plug 205 is fixedly connected to one end of the heat insulation sheet 204. The heat insulation sheet 204 is attached to the surface of the mirror tube 201 and is in contact with the heating element. A protrusion 206 for bending the heating wire 203 is fixedly connected to the top of the heat insulation sheet 204. A notch for the heater is opened on the edge of the plug 205 away from the heat insulation sheet 204, and the plug 207 is inserted into the notch.

[0036] In this technical solution, after the first feeding assembly 300 clamps and rotates the lens barrel 201 to a vertical position, as... Figure 2 and Figure 5 As shown, the heating module is installed by passing it through the through hole 202. Since the inner diameter of the through hole 202 is larger than the width of the heating element, the heating wire 203 passes through the through hole 202 and the heating element is in a horizontal state, which prepares for the subsequent bending of the heating wire 203.

[0037] Again, once the heating wire 203 is in place, the second feeding assembly 500 delivers the plug 205 below the heating wire 203. After the plug 205 is matched with the heating wire 203, it is pushed to insert into the through hole 202. At the same time, the heat insulation sheet 204 is attached to the surface of the lens barrel 201. Then, the second telescopic cylinder 608 feeds the plug block 207 and inserts it into the notch of the plug 205, thereby effectively sealing the through hole 202. This not only clamps and fixes the heating wire 203, but also facilitates the subsequent filling of waterproof glue, improving the assembly efficiency of the lens.

[0038] The first feeding assembly 300 consists of a tilting motor 301, which is fixedly installed on the top surface of the base plate 101. The output end of the tilting motor 301 is fixedly connected to the rotating plate 302, and the rotating plate 302 is rotatably connected to the top surface of the base plate 101. The top of the rotating plate 302 is provided with a gripping mechanism, which consists of a side plate 303 and grippers 304. The side plate 303 is fixedly installed on both sides of the top of the rotating plate 302. Two grippers 304 are rotatably connected to the inner wall of the side plate 303. Both grippers 304 are movably connected to the two telescopic ends of the first bidirectional cylinder 305.

[0039] In this technical solution, after the gripper 304 clamps the bottom of the lens barrel 201 on the guide table 102, the flip motor 301 drives the turntable to rotate, and the turntable 302 drives the side plate 303 and the gripper 304 to rotate from a horizontal state to a vertical state. At this time, the lens barrel 201 is clamped and fixed by the clamping assembly 400 to ensure the stability of the lens barrel 201 during the processing. When the processing is completed, the clamping assembly 400 is released, and the flip motor 301 works in reverse, thereby realizing the unloading of the lens barrel 201.

[0040] The clamping assembly 400 includes a guide rail 401, a slide block 402, and a clamping plate 404. The guide rail 401 has a T-shaped cross-section and is fixedly installed in the middle of the base plate 101. Slide blocks 402 are slidably connected to both ends of the guide rail 401. A clamping plate 404 is fixedly installed on the top of each slide block 402, and the two clamping plates 404 are respectively located on both sides of the lens barrel 201. A second bidirectional cylinder 403 is fixedly installed on the top of the guide rail 401, and the two telescopic ends of the second bidirectional cylinder 403 are fixedly connected to the slide block 402.

[0041] like Figure 4 , Figure 10 As described above, in this technical solution, after the lens is fed by the first feeding component 300, the second bidirectional cylinder 403 shortens and drives the slide 402 and the clamping plate 404 to move synchronously. When the slide 402 moves stably on the surface of the guide rail 401, the clamping plate 404 clamps the two sides of the lens barrel 201, thereby achieving stable fixation of the lens barrel 201.

[0042] like Figures 6-8As shown, the second feeding assembly 500 consists of a first electric push rod 501 and a slider 502. The first electric push rod 501 is fixedly installed on the base plate 101. The telescopic end of the first electric push rod 501 is fixedly connected to the slider 502. A guide rod 503 is sleeved through the slider 502. The two ends of the guide rod 503 are fixedly connected to the guide rail 401 and the base plate 101, respectively. The top of the slider 502 is fixedly connected to the stepper motor 504. The output end of the stepper motor 504 is fixedly connected to the second electric push rod 505. The telescopic end of the second electric push rod 505 is fixedly connected to the swing arm 506 with a bent structure. The top of the swing arm 506 is provided with a suction cup structure for adsorbing the heat insulation sheet 204.

[0043] In this technical solution, when the plug 205 and the heat insulation sheet 204 are being fed, the first electric push rod 501 shortens and drives the slider 502 to move. The slider 502 can achieve stable translation through the guide rod 503. At the same time, the stepper motor 504 drives the swing arm 506 on the second electric push rod 505 to rotate, so that the suction cup structure on the swing arm 506 corresponds to the first placement frame 103. The first electric push rod 501 continues to shorten so that the suction cup structure contacts the heat insulation sheet 204 on the first placement frame 103. After being attracted and fixed by the suction cup structure, the first electric push rod 501 extends, and at the same time, the stepper motor 504 drives the swing arm 506 to rotate back to its original position. Further, after the heating wire 203 passes through the through hole 202, the second feeding assembly 500 is operated. At this time, the heat insulation sheet 204 and the plug 205 are located below the heating wire 203. The second electric push rod 505 extends to drive the heat insulation sheet 204 and the plug 205 to move, so that the notch on the plug 205 corresponds to the heating wire 203. The extension of the second electric push rod 505 stops, and the first electric push rod 501 continues to extend to move the plug 205 into the through hole 202. At the same time, the heat insulation sheet 204 is attached to the surface of the lens barrel 201. After the installation and fixing of the heat insulation sheet 204 is completed, the suction cup structure stops the negative pressure and the second feeding assembly 500 is reset. The first pushing device 105 works to facilitate the continued feeding of the heat insulation sheet 204 and the plug 205.

[0044] like Figures 1-3 As shown in Figures 5 and 9, the third feeding assembly 600 consists of a top plate 601 with support legs. The top plate 601 is fixedly installed in the middle of the base plate 101 by the support legs. A hydraulic cylinder 602 is fixedly installed on one side of the top of the top plate 601. The telescopic end of the hydraulic cylinder 602 passes through the top plate 601 and is fixedly connected to the conveying device 603. The conveying device 603 is set above the first feeding assembly 300 for conveying the heating wire 203.

[0045] In this technical solution, the hydraulic cylinder 602 on the top plate 601 can drive the conveying device 603 to move. When the first feeding component 300 drives the lens barrel 201 to feed, the hydraulic cylinder 602 drives the conveying device 603 to shorten to avoid interference. After the lens barrel 201 is installed in place, the hydraulic cylinder 602 drives the conveying device 603 to move down and correspond to the through hole 202. At this time, the conveying device 603 conveys the heating wire 203 forward so that the heating element passes through the through hole 202 to complete the feeding.

[0046] Furthermore, the conveying device 603 is composed of a flexible roller shaft connected to a motor. The motor drives the flexible roller shaft to rotate, and the roller shaft contacts the heating wire 203, thereby conveying the heating wire 203 and passing it through the through hole 202.

[0047] A first telescopic cylinder 604 is fixedly installed in the middle of the top plate 601. The first telescopic cylinder 604 is inclinedly set at the bottom of the top plate 601. The output end of the first telescopic cylinder 604 is fixedly connected to the pressure block 605. The pressure block 605 has an arc-shaped structure and is set above the lens barrel 201.

[0048] like Figure 6 , 7 As shown, in this technical solution, when the plug 205 is embedded in the through hole 202 and the plug block 207 is inserted into the plug 205, the first telescopic cylinder 604 is activated. The first telescopic cylinder 604 drives the pressure block 605 to contact the heating wire 203 and bend the heating wire 203. During the bending process, the heating wire 203 bends around the protrusion 206 and drives the heating plate at the end to adhere to the heat insulation plate 204. During the bending process, the heating wire 203 is limited by the plug 205 and the plug block 207, and the protrusion can ensure the stable bending of the heating wire 203 and avoid the situation where the heating plate is not arranged in place due to processing errors.

[0049] Specifically, to ensure that the heating element passes smoothly through the through hole 202, the inner diameter of the through hole 202 is larger than the diameter of the heating wire 203. The plug 205 and the block 207 are matched to limit the heating wire 203 and reduce processing errors.

[0050] A fixed shaft 606 is fixedly installed on one side of the support leg of the top plate 601. A gear ring 607 is rotatably connected to the middle of the fixed shaft 606. The gear ring 607 is fixedly connected to the second telescopic cylinder 608. The output end of the second telescopic cylinder 608 is provided with a suction cup structure for adsorbing the block 207. A drive device 609 is installed on the support leg above the fixed shaft 606. The drive device 609 is connected to the gear ring 607 in a transmission connection.

[0051] In this technical solution, the fixed shaft 606 on the support leg can rotate the gear ring 607. The drive device 609 is preferably composed of gears with a motor. When the drive device 609 drives the gear ring 607 to rotate, the gear ring 607 rotates around the fixed shaft 606 and drives the second telescopic cylinder 608 to rotate to a vertical position. At this time, the second telescopic cylinder 608 extends, so that the suction cup structure on its telescopic end corresponds to the second placement frame 104. The suction cup structure adsorbs and fixes the block 207 on the second pushing device 106. The second telescopic cylinder 608 shortens and works in the opposite direction through the drive device 609, so that it drives the block 207 to move to the corresponding position of the through hole 202. The second telescopic cylinder 608 continues to extend, so that it drives the block 207 to translate and lock into the notch of the plug 205, thereby achieving the sealing of one side of the through hole 202 and simultaneously fixing the heating wire 203 stably.

[0052] Furthermore, after the second telescopic cylinder 608 completes the installation and reset of the block 207, the first telescopic cylinder 604 starts to work, driving the pressure block 605 to contact the heating wire 203. When the heating wire 203 bends around the protrusion 206, it causes the heating plate to adhere to the heat insulation plate 204. Finally, after the outermost lens is installed, the lens presses the heating plate tightly onto the heat insulation plate 204 to achieve fixation. After the screw cap 209 is fixed, when the heated lens is used, the heating plate heats the outermost lens. The heat is insulated by the heat insulation plate 204, allowing most of the heat to be transferred to the lens, thereby achieving the defogging function.

[0053] In summary, the present invention has been described in detail through specific embodiments. Those skilled in the art will understand that the present invention is not limited to the above embodiments, and various changes or modifications can be made to these embodiments. Regardless of any changes in their shape or structure, such changes and modifications should fall within the protection scope of the present invention without departing from the principles and essence of the present invention. The protection scope of the present invention is defined by the appended claims.
