Description

Technical Field

[0001] This invention relates to the field of optical lens placement rack technology, and more specifically to a placement rack for processing optical lenses. Background Technology

[0002] Optical lenses are optical elements made of optical glass or optical resin that can change the direction of light propagation and regulate the relative spectral distribution of ultraviolet, visible, or infrared light. They have many superior properties, including high light transmittance, constant refractive index, and stable physicochemical properties. These characteristics make optical lenses widely used in various optical instruments such as telescopes, microscopes, and camera lenses.

[0003] In optical laboratories, production workshops, and various occasions where optical instruments are used, optical lenses are usually placed in specially designed optical lens racks to provide a stable support environment and prevent damage to the lenses during storage, transportation, or use.

[0004] Optical lenses can be divided into glass lenses and resin lenses according to their materials. For the placement of large-diameter resin lenses such as prescription sunglasses or tinted glasses, traditional storage racks use a flat placement method. This method can easily cause friction between the lens and the bottom surface, resulting in scratches and reducing the practical performance of the optical lens. At the same time, the existing clamping structure is a fixed design, which cannot flexibly extend and retract the clamping head according to the operation requirements, resulting in inconvenience in picking up and putting down and the risk of scratching the optical lens.

[0005] In light of the aforementioned problems, there is an urgent need to develop a storage rack for optical lenses during processing. By introducing a mechanical linkage structure, optical lenses can be stored vertically, reducing wear and tear on the lenses on the rack. Simultaneously, the clamping head can be flexibly extended and retracted according to retrieval needs, improving the safety of optical lens storage. Summary of the Invention

[0006] In view of the problems raised in the background art, the present invention provides a placement rack for processing optical lenses to solve the problems, and the present invention will be further described below.

[0007] A placement rack for processing optical lenses includes at least three identical support frames. Each support frame has sliding grooves on both side walls. A lifting member is slidably connected between two sliding grooves of the same support frame. The top of the lifting member is provided with multiple clamping stations. Each clamping station is provided with two symmetrically distributed clamping members. Both ends of the lifting member are fixedly connected with sliding columns. The sliding columns are slidably connected to the adjacent sliding grooves. The sliding columns on the same side of two adjacent support frames are hinged by connecting rods.

[0008] Preferably, each of the lifting members has two symmetrically distributed and close-to-each-other clamping members slidingly at its clamping position, and each clamping member and the lifting member is provided with a compression spring.

[0009] Preferably, each lifting component has two symmetrically distributed locking blocks at its clamping station. The bottom of each locking block is connected to a rotating component via a rotating ring. A return spring is compressed between the rotating component and the adjacent locking block. The return spring is wound around the adjacent rotating ring. Guide frames are fixedly connected to the same side of the three lifting components. Inclined grooves are opened at both ends of each guide frame.

[0010] Preferably, each of the lifting components has a T-shaped frame fixed to its bottom, and an extrusion plate matching the clamping position of the lifting component is fixed to the T-shaped frame. Extrusion rods are fixed to the left and right ends of the first and last two T-shaped frames, and the extrusion rods are slidably connected in the adjacent grooves. The three T-shaped frames are connected by a bidirectional telescopic key.

[0011] Preferably, the extrusion plate is centered between two adjacent rotating parts, and the extrusion plate is in extrusion engagement with the two rotating parts.

[0012] Preferably, two adjacent support frames are slidably connected to a slide rod at their bottoms, and a compression spring is provided between the bottoms of two adjacent support frames, with the compression spring wrapped around the adjacent slide rod.

[0013] Preferably, the left side walls of both the first and last support frames are fixedly connected to a connecting frame, and the ends of the connecting frames are keyed with one-way locking teeth. The side wall of the middle support frame has two symmetrically distributed locking members that slide together. A guide member slides through the two locking members and a positioning plate is fixedly connected to the guide member. The positioning plate is located in the middle of the two locking members, and a linear spring is compressed between each locking member and the positioning plate.

[0014] Preferably, the two locking components are distributed between two unidirectional locking teeth, and each locking component is fixedly connected to a limiting tooth, which engages with the adjacent unidirectional locking tooth.

[0015] Beneficial effects: Compared with existing technologies, this device, when an external force is applied between adjacent support frames, causes the connecting rod to open and close in a controlled manner, driving the lifting component to move. The two symmetrically distributed clamping components and the clamped lenses also move accordingly, allowing the clamped lenses to be flexibly pushed out or hidden according to retrieval needs, improving the safety of optical lens storage. Through the movement of the lifting component, the extrusion rod moves under the guidance of the groove, linking the T-shaped frame and the extrusion plate to move, driving the two rotating components to rotate. This allows the locking block to flexibly clamp the lens edge when the support frame is retracted, and releases the clamping constraint on the lens edge when the support frame is extended, achieving flexible release control of the lens clamping state and facilitating lens retrieval. The engagement of the limiting teeth with the corresponding one-way locking teeth achieves a position locking function, preventing unexpected retraction of adjacent support frames due to external disturbances or equipment vibration, thus achieving dynamic positioning and spacing maintenance of the support frames in the extended state.

Detailed Implementation

[0023] Next, combine Figures 1-6 A specific embodiment of the present invention will be described in detail below.

[0024] refer to Figure 1 and Figure 2 A placement rack for processing optical lenses includes at least three identical support frames 1. Each support frame 1 has a sliding groove 10 on both side walls. A lifting member 13 is slidably connected between two sliding grooves 10 of the same support frame 1. The top of the lifting member 13 is provided with multiple clamping positions. Each clamping position is provided with two symmetrically distributed clamping members 15 for stably clamping multiple resin optical lenses (hereinafter collectively referred to as "lenses") in an upright posture. Both ends of the lifting member 13 are fixedly connected with sliding columns 14. The sliding columns 14 are slidably connected through the adjacent sliding grooves 10 and extend outward to form a linkage fulcrum. The sliding columns 14 on the same side of two adjacent support frames 1 are hinged by a connecting rod 11.

[0025] The lens is held vertically by two clamping members 15. When an external contraction force is applied between adjacent support frames 1, the connecting rod 11 is folded in a controlled manner, causing the lifting member 13 to move down synchronously along the slide groove 10. The two symmetrically distributed clamping members 15 installed on it, and the lens held by the clamping members 15, also move down as a whole until they enter the safe area inside the support frame 1, thus realizing the storage and protection function.

[0026] Conversely, when an external unfolding force is applied to move adjacent support frames 1 away from each other, the connecting rod 11 unfolds in a controlled manner, driving the lifting member 13 to move upward along the slide groove 10. The two symmetrically distributed clamping members 15 installed on it, and the lenses clamped by the clamping members 15, also move upward as a whole, thereby synchronously lifting the lenses in the clamping members 15 to a height position that is easy to operate, realizing automatic positioning and pick-up and drop auxiliary functions.

[0027] Compared to the traditional flat placement method, this method can effectively reduce the clamping area of ​​the lens by the device. At the same time, the lens held by the clamping component 15 can be flexibly pushed out and hidden according to the needs of use, which improves the safety of optical lens storage.

[0028] To facilitate the clamping action of the clamping member 15 on the lens, two symmetrically distributed and close to each other clamping members 15 are slidably connected at the clamping position of each lifting member 13. A compression spring 12 is provided between the clamping member 15 and the lifting member 13 to provide a continuous elastic preload for the two clamping members 15 at the same clamping position, so that they always remain close to each other when no external force is applied.

[0029] The lens is inserted from top to bottom into the gap between two close clamping members 15. Under the pressure of the compression spring 12, the clamping member 15 will apply a uniform clamping force to the edge of the lens, so as to achieve stable clamping and fixing of it in an upright position. This method reduces the contact area between the clamping member and the lens, thereby reducing the risk of scratches or damage caused by friction and pressure concentration.

[0030] As described in the background art, in the case of placing large-diameter resin lenses such as prescription sunglasses or tinted glasses, the clamping member 15 only clamps and stabilizes the bottom of the lens. In order to increase the stability of large-diameter lenses in this device, the device is designed in the following way.

[0031] refer to Figure 3 Each lifting member 13 has two symmetrically distributed locking blocks 24 at its clamping station. The two locking blocks 24 are distributed on both sides of the clamped lens. That is, the two locking blocks 24 cooperate with the two adjacent clamping members 15 to form a multi-directional limiting and protection structure for the lens, which enhances the clamping stability of the lens and effectively prevents the lens from tipping over, shifting or shaking during placement, movement or equipment vibration, thereby avoiding the risk of lens damage or falling.

[0032] To achieve dynamic clamping control of the lens at different operating stages, this device uses a structural linkage design to automatically adjust the clamping force of the two clamping blocks 24 on the lens according to the scaling state of the support frame 1, thereby providing clamping protection and convenient handling under different working conditions. The specific method is as follows.

[0033] refer to Figure 4 The bottom of each of the locking blocks 24 is connected to a rotating component 23 via a rotating ring 27. A return spring 25 is compressed between the rotating component 23 and the adjacent locking block 24. The purpose is to achieve linkage between the rotating component 23 and the adjacent locking block 24 through the return spring 25. The return spring 25 is wound around the adjacent rotating ring 27.

[0034] refer to Figure 3 Each of the three lifting components 13 is fixedly connected to a guide frame 2 on the same side. That is, two guide frames 2 are distributed on the left and right inner sides of the three lifting components 13. Each guide frame 2 has an inclined groove 26 at both ends. That is, two grooves 26 correspond to the inner sides of the first and last support frames 1 respectively, and there are no grooves 26 distributed on the left and right inner sides of the middle support frame 1.

[0035] Each of the lifting components 13 has a T-shaped frame 21 fixedly attached to its bottom. A pressing plate 28 matching the clamping position of the lifting component 13 is fixedly attached to the T-shaped frame 21. Pressing rods 211 are fixedly attached to the left and right ends of the first and last T-shaped frames 21. The pressing rods 211 are slidably connected in the adjacent grooves 26. The three T-shaped frames 21 are connected by a key of a bidirectional telescopic component 22. That is, the first and last T-shaped frames 21 are respectively connected to the two telescopic ends of the bidirectional telescopic component 22, and the middle T-shaped frame 21 is connected to the fixed end of the bidirectional telescopic component 22.

[0036] refer to Figure 4The extrusion plate 28 is centrally located between the bottoms of the two adjacent rotating parts 23. The extrusion plate 28 and the two rotating parts 23 are pressed together to realize the opening and closing of the two rotating parts 23.

[0037] When an external contraction force is applied between adjacent support frames 1, the connecting rod 11 is folded in a controlled manner, causing the lifting member 13 to move downward, and the clamping member 15 and the lens it clamps also move downward as a whole, so that the lens enters the safe area inside the support frame 1, realizing the storage and protection function.

[0038] Simultaneously, the guide frame 2 fixed to the lifting member 13 moves downward. Based on the inclined groove 26 design, the extrusion rod 211 moves downward in a controlled manner, the linkage T-shaped frame 21 moves downward, and the extrusion plate 28 moves downward in a controlled manner and extrudes the two adjacent rotating members 23, causing the bottoms of the two rotating members 23 to separate from each other and their tops to approach each other. The return spring 25 deforms, and under the action of the return spring 25 and the rotating ring 27, the locking block 24, under the influence of the tendency of the tops of the rotating members 23 to approach each other, exhibits a slow movement state of approaching each other. Since the return spring 25 has a buffering characteristic, the approach amplitude of the locking block 24 is less than the rotational displacement of the rotating member 23 itself, thereby achieving flexible and close clamping of the lens edge and avoiding damage to the lens due to excessive clamping force.

[0039] When an external force is applied to move adjacent support frames 1 away from each other, the connecting rod 11 unfolds, driving the lifting member 13 to move upward along the slide groove 10. The two symmetrically distributed clamping members 15 installed on it, as well as the lens, also move upward as a whole, thereby moving the lens to a height position that is easy to operate, realizing automatic positioning and pick-up / placement auxiliary functions.

[0040] Simultaneously, the guide frame 2 fixed to the lifting member 13 moves upward. Based on the inclined groove 26 design, the pressing rod 211 moves upward in a controlled manner, the linkage T-shaped frame 21 moves upward, and the pressing plate 28 moves upward in a controlled manner to gradually detach from the pressing of the two rotating members 23. Under the action of the return spring 25, the two rotating members 23, which were originally pressed inward, begin to rotate outward to reset. Their top spacing increases and their bottom spacing decreases. Then, the linkage locking block 24 rotates outward to reset and releases the clamping constraint on the edge of the lens, realizing the release control of the lens clamping state, which facilitates the removal of the lens.

[0041] During the process of the two locking blocks 24 rotating outward and separating under the drive of the linkage structure, an open gap is formed between the limiting surfaces that contact the lens, allowing the lens to be inserted. At this time, the operator inserts the optical lens to be clamped vertically from top to bottom into the space between the two locking blocks 24, and continues to move it down until the lens enters between the two symmetrically distributed clamping members 15. As the lens continues to be inserted down, the clamping members 15, which maintain a tendency to move closer under the action of the compression spring 12, will apply a uniform clamping force to the edge of the lens, thereby achieving stable positioning and automatic clamping of the lens, and completing the entire loading and clamping action.

[0042] To achieve position locking of adjacent support frames 1 in the unfolded state, this device is equipped with a locking component to maintain their relative distance after the support frames 1 are unfolded and to prevent unintended shrinkage.

[0043] refer to Figure 5 and Figure 6 Two adjacent support frames 1 are slidably connected to a slide rod 35 at their bottoms, which serves as a guide and connection fulcrum for the expansion displacement of the support frame 1. A compression spring 36 is provided between the bottoms of two adjacent support frames 1. The compression spring 36 is wound around the adjacent slide rod 35, which aims to maintain the distance between the two adjacent support frames 1 through the compression spring 36.

[0044] A connecting frame 3 is fixedly connected to the left side wall of both the first and last support frames 1. The ends of the connecting frames 3 are keyed with one-way locking teeth 31. The two one-way locking teeth 31 are spaced apart and parallel vertically, and are distributed on the side wall of the middle support frame 1. Two symmetrically distributed locking members 32 are slidably connected to the side wall of the middle support frame 1. A guide member 34 is slidably connected through the two locking members 32. The guide member 34 is used to guide the movement trajectory of the locking members 32. That is, the locking members 32 can only slide vertically up and down. A positioning plate 37 is fixedly connected to the guide member 34. The positioning plate 37 is located in the middle of the two locking members 32 and serves as the support reference of the elastic reset system. A linear spring 33 is compressed between each locking member 32 and the positioning plate 37 to provide a constant elastic reset force for the two locking members 32, so that they always maintain an outward opening tendency when no external force is applied.

[0045] Two locking components 32 are distributed between two unidirectional locking teeth 31. Each locking component 32 is fixedly connected to a limiting tooth 38. The limiting tooth 38 engages with the adjacent unidirectional locking tooth 31 to form a mechanical linkage locking structure.

[0046] When an external contraction force is applied between adjacent support frames 1, the adjacent support frames 1 move closer to each other, compressing the spring 36 and causing it to deform. This, in turn, moves the connecting frame 3, causing the two one-way locking teeth 31 to move towards each other. During this process, the limiting tooth 38 remains engaged with the corresponding one-way locking tooth 31, achieving position locking. This engagement structure remains effective even after the support frame 1 has been extended to the set position. The limiting tooth 38 applies reverse resistance to the one-way locking tooth 31, preventing it from unexpectedly retracting due to external disturbances or equipment vibration. This achieves the dynamic positioning and spacing maintenance function of the support frame 1 in its extended state.

[0047] External force drives the two locking parts 32 to move closer to each other, the linear spring 33 deforms, and the limiting teeth 38 disengage from the adjacent one-way locking teeth 31. As a result, the limiting teeth 38 cancel the reverse resistance to the one-way locking teeth 31. At this time, the adjacent support frame 1 moves and resets in the direction away from each other under the action of the compression spring 36.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
