Description

Technical Field

[0001] This invention belongs to the field of optical prism manufacturing and processing technology, and specifically relates to an optical prism strip positioning, gluing and cutting device. Background Technology

[0002] A prism is a transparent object formed by two intersecting but non-parallel planes used to split light or cause light beams to disperse. Prisms are polyhedrons made of transparent materials (such as glass and crystal) and are widely used in optical instruments. Prisms can be classified into several types according to their properties and uses. For example, in spectroscopic instruments, "dispersive prisms" decompose composite light into spectra, and equilateral triangular prisms are commonly used. In instruments such as periscopes and binoculars, prisms that change the direction of light to adjust the imaging position are called "total internal reflection prisms," and right-angle prisms are generally used. In order to improve the processing efficiency of prisms, cutting equipment is needed to cut prisms during the manufacturing process.

[0003] In the prior art, Chinese utility model publication number CN214562048U discloses an optical prism cutting device, comprising a main body, a water tank fixedly connected to the bottom of the main body, a water collection trough fixedly connected to the inner bottom of the main body, a pipe fixedly connected to the bottom of the water collection trough, a filter screen movably connected inside the pipe near its top edge, one end of the pipe extending into the water tank, the inner bottom of the water collection trough being inclined, a strainer fixedly connected inside the main body, a fixing block fixedly connected to the upper surface of the strainer, a servo motor fixedly connected inside the fixing block near its left and right edges, a drive gear fixedly connected to the output end of the servo motor, a driven gear meshing with the outer surface of the drive gear, and a nut fixedly connected to the inner surface of the driven gear. This device has a simple and reasonable structure, effectively addresses the shortcomings of the prior art, effectively improves the efficiency of coolant use, and helps reduce waste.

[0004] The aforementioned cutting equipment typically performs positioning and cutting of individual prisms, requiring significant manual operation and making it inconvenient to simultaneously position multiple prisms in batches, thus reducing cutting efficiency. Furthermore, after cutting, the prisms need to be transferred to specialized polishing equipment for polishing, increasing the processing steps and further reducing efficiency. Frequent transfers and contact with the prism surface can also lead to poor prism appearance, affecting processing quality. Therefore, we need to propose an optical prism strip positioning and bonding cutting device to address these problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an optical prism strip positioning, bonding, and cutting device, comprising a machine tool, a driving assembly on the upper surface of the machine tool, a flipping assembly for flipping the bonded prism strip substrate on the driving assembly, a limiting frame for placing the substrate on the upper surface of the machine tool, a positioning fixture for embedding multiple prism strips on the upper surface of the machine tool, two sets of vertical plates and an impregnation tank on the upper surface of the machine tool, the impregnation tank for bonding the cut substrate, an integral conveying assembly, a split conveying assembly, and a double polishing assembly arranged sequentially from top to bottom on opposite sides of the two sets of vertical plates, the double polishing assembly being disposed inside the split conveying assembly and used for polishing the prism strips on both sides of the bonded substrate, and a cutting mechanism for cutting the bonded prism substrate mounted on the upper surface of the two sets of vertical plates;

[0006] The positioning fixture includes an open frame, inside which two sets of support plates are detachably connected, and the upper surface of both sets of support plates is provided with positioning grooves for embedding prism strips.

[0007] The dual-polishing assembly includes two layers of polishing rollers for polishing the prism. Multiple polishing rollers are provided in both layers, and the two layers of polishing rollers are arranged alternately in a staggered manner. Each polishing roller has a double sprocket shaft at one end, and a double polishing chain is connected between adjacent sets of double sprocket shafts.

[0008] Furthermore, the cutting mechanism includes a mounting frame, a transmission assembly, a cutting assembly, and a limiting assembly. The transmission assembly is mounted on the top of the inner cavity of the mounting frame, and the cutting assembly is driven by the transmission assembly.

[0009] Furthermore, the transmission assembly includes two sets of fixed plates fixedly connected to the top of the inner cavity of the mounting frame. Two sets of adjusting screws are rotatably connected to opposite sides of the two sets of fixed plates. One end of each set of adjusting screws passes through one set of fixed plates and is fixedly connected to a cutting sprocket. Both sets of cutting sprockets are driven by a cutting chain. One end of one set of adjusting screws passes through the other set of fixed plates and is driven by a fifth motor.

[0010] Furthermore, the cutting assembly includes a movable seat and a multi-station laser cutter. A mating strip is fixedly connected to the upper surface of the multi-station laser cutter. A mating groove for the mating strip to be embedded is opened on the lower surface of the movable seat. A protrusion that abuts against one side of the movable seat is fixedly connected to one end of the mating strip, and a positioning bolt that is threadedly connected to the movable seat is inserted into one side of the protrusion.

[0011] Furthermore, the limiting component includes a baffle frame and two sets of cylinders symmetrically arranged on both sides of the mounting frame. The telescopic ends of the two sets of clamping cylinders pass through the mounting frame and are fixedly connected to clamping plates. The baffle frame is used to limit the cutting of the substrate prism.

[0012] Furthermore, the flipping assembly includes a support, a driving component, and an adsorption assembly. The support is used to mount the driving component and the adsorption assembly. The driving component is used to flip the adsorption assembly, and the adsorption assembly is used to adsorb and fix the substrate.

[0013] Furthermore, the overall conveying assembly includes two sets of third conveying rollers and four sets of synchronous pulleys. The two sets of third conveying rollers are driven by vacuum belts, and each pair of synchronous pulleys is driven by a synchronous belt. One side of one of the vertical plates is provided with a negative pressure fan connected to the inner cavity of the vacuum belt.

[0014] Furthermore, a connecting shaft is fixedly connected between the two sets of synchronous pulleys, and one end of the connecting shaft is fixedly connected to one end of one of the third conveying rollers with an integral sprocket, and the two sets of integral sprockets are driven by an integral chain.

Both ends of the two sets of first conveying rollers are driven to be connected to a first conveyor belt, and both ends of the two sets of second conveying rollers are driven to be connected to a second conveyor belt.

[0016] Furthermore, the dual-throw assembly also includes a limiting plate disposed inside the first conveyor belt and the second conveyor belt. The outer surface of the first conveyor belt is provided with a first slot with equal spacing, and the outer surface of the second conveyor belt is provided with a second slot with equal spacing. The first slot and the second slot fit together.

[0017] The beneficial effects of this invention are:

[0018] 1. The present invention utilizes a flipping component, an integral conveying component, a cutting mechanism, and a split conveying component in combination. The flipping component facilitates the movement of the glued prisms to the integral conveying component, where they are then split and cut by the cutting mechanism above the integral conveying component. After cutting, the prisms are glued together in pairs and then conveyed to the double polishing component for polishing via the split conveying component. This eliminates the need for additional professional polishing equipment to polish the prisms, reduces the frequency of prism movement, and lowers the labor intensity of workers, thereby effectively reducing production costs.

[0019] 2. This invention utilizes the cooperation of polishing rollers, a second motor, a double sprocket shaft, and a double polishing chain. The second motor provides kinetic energy to the polishing rollers, and multiple polishing rollers rotate synchronously under the linkage of the double sprocket shaft and the double polishing chain, thereby facilitating double-sided polishing of the prism. In terms of personnel skills, it reduces the skill requirements, making personnel easy to train and quick to learn. In terms of process, it enables batch processing of products and avoids the impact of repeated flipping on product processing efficiency.

[0020] 3. This invention uses the combination of an open frame, a support plate, and a positioning groove to embed multiple prism strips into the positioning grooves on two sets of support plates, thereby enabling the placement of multiple prism strips and allowing them to be glued together at once. This avoids the risk of poor appearance caused by repeated gluing and improves production efficiency.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-9As shown, this embodiment of the invention provides an optical prism strip positioning, bonding, and cutting device, including a machine tool 1. A positioning fixture 2, two sets of upright plates 4, and a drive assembly 14 are mounted on the upper surface of the machine tool 1. The positioning fixture 2 is used to place multiple prism strips for bonding to a substrate. The drive assembly 14 is equipped with a flipping assembly 3 for conveying the substrate. The flipping assembly 3 facilitates the adsorption of the substrate, thereby bonding it to the prism strips in the positioning fixture 2. A double-throwing assembly 5, a separate conveying assembly 6, and an integral conveying assembly 7 are arranged between the two sets of upright plates 4. The flipping assembly 3 flips the substrate after bonding the long prism strips, allowing the substrate to be driven by the drive assembly 14. The assembly moves downwards to the top of the overall conveying assembly 7. The split conveying assembly 6 is located directly below the overall conveying assembly 7, and the double polishing assembly 5 is located inside the split conveying assembly 6. The overall conveying assembly 7 conveys the substrate of the glued prism strip. The upper surfaces of the two sets of upright plates 4 are equipped with a cutting mechanism 8 for positioning and cutting the prism strip. The cutting mechanism 8 positions the substrate and performs laser cutting. The cut substrates are bonded together in pairs and then conveyed by the split conveying assembly 6 so that the prism can be polished by the double polishing assembly 5, thereby improving the polishing efficiency of the prism, reducing the workload of the workers, completing the batch processing of the product, and avoiding the impact of flipping back and forth on the product processing efficiency.

[0035] like Figure 3 As shown, the positioning fixture 2 includes an open frame 21, inside which two sets of support plates 22 are detachably connected. The upper surfaces of the two sets of support plates 22 are respectively provided with multiple positioning grooves 23 for fitting prism strips. The multiple positioning grooves 23 are equally spaced to place multiple prism strips and then glue them to the substrate, thereby positioning and cutting multiple prism strips, improving efficiency, reducing contact with prisms. By operating with the dedicated positioning fixture 2, the accuracy of product gluing is ensured, and repeated flipping and gluing are avoided, which would result in poor product appearance.

[0036] like Figure 5 As shown, the double polishing assembly 5 includes two sets of limiting plates 51 fixedly connected to opposite sides of two sets of upright plates 4. Multiple polishing rollers 52 are rotatably connected between the two sets of limiting plates 51. One end of each set of polishing rollers 52 is fixedly connected to a double sprocket shaft 54, and adjacent double sprocket shafts 54 are connected by a double polishing chain 55. The other end of one set of polishing rollers 52 passes through the upright plate 4 and is driven by a second motor 53. The second motor 53 provides kinetic energy and drives multiple polishing rollers 52 through the double sprocket shaft 54 ​​and the double polishing chain 55, thereby polishing the prisms on the two sets of substrates that have been cut and glued together. The double polishing method improves the processing efficiency of the prisms.

[0037] like Figure 2As shown, the drive assembly 14 includes two sets of columns 141 fixedly connected to one end of the upper surface of the machine tool 1, and a drive screw 143 and a guide rod 144 are installed between the two sets of columns 141 in parallel. One end of the drive screw 143 passes through one set of columns 141 and is driven by a sixth motor 142. The sixth motor 142 drives the drive screw 143 to rotate, which facilitates the position adjustment of the flipping assembly 3 and improves the bonding efficiency between the prism and the substrate.

[0038] like Figure 1 As shown, the upper surface of the processing machine tool 1 is provided with a limiting frame 10 for placing the glued prism strip substrate, and the cross-section of the limiting frame 10 is U-shaped. The upper surface of the processing machine tool 1 is provided with a collection tray 11 for stacking the double-polished prism substrate strips. The double-polished prisms are collected uniformly by the collection tray 11 and then carried out to the next process. The upper surface of the processing machine tool 1 is provided with a glue dipping tank 9, which is used to dip one side of the cut substrate into glue, thereby gluing the two sets of substrates together, and then conveying them through the split conveying assembly 6 for double polishing.

[0039] like Figure 4 As shown, the flipping assembly includes a support, a driving component, and an adsorption assembly. The support is used to mount the driving component and the adsorption assembly. The driving component is used to flip the adsorption assembly, and the adsorption assembly is used to adsorb and fix the substrate.

[0040] The support of the flipping assembly 3 is a movable base 31, and the driving components are a first motor 32 and a rotating shaft 33. The adsorption assembly includes a mounting plate 34, a telescopic cylinder 35, a hollow disk 38, and a vacuum suction cup 39. The movable base 31 is threadedly driven by the drive screw 143 and limited by the guide rod 144. The movable base 31 moves along the guide rod 144. The first motor 32 is installed on one side of the movable base 31. The output shaft of the first motor 32 is driven and connected to the rotating shaft 33. One end of the rotating shaft 33 passes through the movable base 31 and is fixedly connected to the mounting plate 34. The first motor 32 is used to drive the rotating shaft 33 to rotate the mounting plate 34 from 0 to 180°, so that the prism on the substrate faces upward.

[0041] A telescopic cylinder 35 is provided in the middle of the upper surface of the mounting plate 34. The telescopic end of the telescopic cylinder 35 passes through the mounting plate 34 and is fixedly connected to the hollow disk 38. Multiple sets of stabilizing rods 36 are slidably inserted into the upper surface of the mounting plate 34 and fixedly connected to the hollow disk 38. The telescopic cylinder 35 is used to adjust the position of the hollow disk 38 and to ensure the horizontal lifting and lowering of the hollow disk 38 through the stabilizing rods 36.

[0042] An air pump 37 is provided on the lower surface of the mounting plate 34. The air pump 37 is connected to the inner cavity of the hollow disk 38. The lower surface of the hollow disk 38 is provided with multiple sets of vacuum suction cups 39. The air pump 37 adjusts the pressure in the inner cavity of the hollow disk 38, and then the multiple sets of vacuum suction cups 39 adsorb the substrate in the limiting frame 10, so that it can be moved to the positioning fixture 2 under the action of the driving component 14. This allows the prism strip in the positioning fixture 2 to be glued to the substrate in one go, avoiding the risk of poor appearance caused by repeated gluing.

[0043] like Figure 7 As shown, the overall conveying assembly 7 includes two sets of third conveying rollers 75 rotatably connected between two sets of vertical plates 4 and multiple sets of support rollers 79. The two sets of third conveying rollers 75 are drivenly connected to a vacuum belt 78. The multiple sets of support rollers 79 are all arranged in the inner cavity of the vacuum belt 78. The multiple sets of support rollers 79 are used to support the vacuum belt 78, thereby ensuring the stability of the substrate conveyed on it.

[0044] The overall conveying assembly 7 also includes two sets of synchronous pulleys 72 rotatably connected to the upper ends of the opposite sides of the two sets of upright plates 4. Each pair of synchronous pulleys 72 is connected to a synchronous belt 74, and a connecting shaft 73 is fixedly connected between the two sets of corresponding synchronous pulleys 72. One end of the connecting shaft 73 passes through the upright plate 4 and is driven by a fourth motor 71. The other end of the connecting shaft 73 and one end of one set of third conveying rollers 75 both pass through the upright plate 4 and are fixedly connected to an integral sprocket 76. Both sets of integral sprockets 76 are engaged with integral chains 77. The fourth motor 71 drives the connecting shaft 73, causing the synchronous pulleys 72 to drive the synchronous belts 74 to convey the substrate flipped by the flipping assembly 3. Then, under the action of the integral sprockets 76 and integral chains 77, the substrate is conveyed to the vacuum belt 78, improving the conveying efficiency. A negative pressure fan 13 is provided above one side of one set of upright plates 4, which communicates with the inner cavity of the vacuum belt 78. By extracting the air inside the vacuum belt 78, the pressure difference is used to fix the substrate on the surface of the vacuum belt 78, thereby improving the stability of the conveying.

[0045] like Figure 8-9 As shown, the cutting mechanism 8 includes a mounting frame 81, a transmission assembly, a cutting assembly 810, and two sets of limiting assemblies. The transmission assembly includes two sets of fixing plates 83 disposed at the top of the mounting frame 81, and two sets of adjusting screws 87 are rotatably connected between the two sets of fixing plates 83. One end of each set of adjusting screws 87 passes through one set of fixing plates 83 and is fixedly connected to a cutting sprocket 88. Both sets of cutting sprockets 88 are engaged with a cutting chain 89. Both sets of adjusting screws 87 are driven to the cutting assembly 810. The other end of one set of adjusting screws 87 passes through the other set of fixing plates 83 and is driven by a fifth motor 86. The fifth motor 86 provides kinetic energy, thereby enabling the two sets of adjusting screws 87 to adjust the position of the cutting assembly 810, so as to cut the substrate and prism strip and improve the cutting efficiency.

[0046] The limiting component includes a baffle frame 82 and two sets of clamping cylinders 84 symmetrically arranged on both sides of the mounting frame 81. The telescopic ends of the two sets of clamping cylinders 84 pass through the mounting frame 81 and are fixedly connected to clamping plates 85. The clamping plates 85 clamp and position the substrate and prism, thereby improving the stability of the substrate during cutting. The baffle frame 82 facilitates the limiting of the cut substrate and prism strip to prevent them from falling and being damaged. This also makes it easier for workers to hold the two sets of substrates, dip them in glue, and then glue them together.

[0047] The cutting assembly 810 includes a movable seat 8101 that is drivenly connected to two sets of adjusting screws 87. A detachable multi-station laser cutter 8103 is provided below the movable seat 8101. A connecting strip 8104 is fixedly connected to the upper end of the multi-station laser cutter 8103. A connecting groove 8102 for the connecting strip 8104 to be inserted is provided on the lower surface of the movable seat 8101. A protrusion 8105 is fixedly connected to one end of the connecting strip 8104, and a positioning bolt 8106 that is threadedly connected to one side of the movable seat 8101 is inserted into the protrusion 8105. The protrusion 8105 is fixed by the positioning bolt 8106, so that the multi-station laser cutter 8103 can move stably with the movable seat 8101. It is easy to disassemble and assemble, and easy to replace different multi-station laser cutters 8103.

[0048] like Figure 6 As shown, the split conveying assembly 6 includes two sets of first conveying rollers 62 and two sets of second conveying rollers 63. Both ends of the two sets of first conveying rollers 62 are drivenly connected to a first conveyor belt 64. The outer surface of the first conveyor belt 64 is provided with multiple sets of first slots 65. Both ends of the two sets of second conveying rollers 63 are drivenly connected to a second conveyor belt 66, and the outer surface of the second conveyor belt 66 is provided with multiple sets of second slots 67. The multiple sets of first slots 65 and the multiple sets of second slots 67 are equally spaced, and the multiple sets of first slots 65 respectively fit into the multiple sets of second slots 67. The first slots 65 and the second slots 67 facilitate the embedding of the cut substrate, thereby enabling the prism to stably pass through the double polishing assembly 5 and improving the polishing efficiency of the prism.

[0049] One end of one set of first conveyor rollers 62 is driven by a third motor 61. One end of the other set of first conveyor rollers 62 and one end of one set of second conveyor rollers 63 are both provided with separate sprockets 68. Both sets of separate sprockets 68 are connected to separate chains 69. The third motor 61 provides kinetic energy to make one set of first conveyor rollers 62 rotate, which in turn makes the other set of first conveyor rollers 62 rotate under the action of the two sets of first conveyor belts 64. The second conveyor rollers 63 rotate synchronously under the action of the separate sprockets 68 and separate chains 69, so that the first conveyor belts 64 and the second conveyor belts 66 rotate synchronously, which facilitates the conveying of the substrate and improves the conveying efficiency. At the same time, the limiting plate 51 of the double polishing component 5 is set inside the first conveyor belts 64 and the second conveyor belts 66, thereby supporting the first conveyor belts 64 and the second conveyor belts 66 and preventing them from loosening when conveying the cut substrate, thus improving the polishing efficiency of the prism.

[0050] like Figure 1 As shown, a guide block 12 is provided on the upper surface of the processing machine tool 1. The cross-section of the guide block 12 is triangular. The guide block 12 is located below another set of first conveying rollers 62. The guide block 12 facilitates the polished prism substrate to push out of the first slot 65, thereby facilitating the collection of the polished prism and making it easier to proceed to the next process. In terms of personnel skills, it reduces the skill requirements for personnel, making it easy for personnel to train and learn quickly.

[0051] In use, multiple substrates are placed in the limiting frame 10, and multiple prism strips are placed in the positioning grooves 23 on the two sets of support plates 22. The telescopic cylinder 35 is activated to drive the hollow plate 38 to descend so that the vacuum suction cup 39 touches the substrate. The air pump 37 removes the air from the hollow plate, so that the vacuum suction cup 39 adsorbs the substrate. After the telescopic cylinder 35 is reset, the sixth motor 142 is activated and the drive screw 143 drives the moving seat 31 to move along the guide rod 144, so that the substrate adsorbed by the flipping component 3 is moved above the positioning fixture 2. The telescopic cylinder 35 repeats the operation, so that the prism strips coated with glue are glued to the lower surface of the substrate. After the telescopic cylinder 35 is reset again, the drive screw 143 drives the flipping component 3 to move above the collection plate 11. The first motor 32 drives the rotating shaft 33 to rotate the mounting plate 34 180 degrees, so that the substrate is moved to the synchronous belt 74 of the overall conveying component 7. The air pump 37 presses so that the vacuum suction cup 39 does not adsorb the substrate, so that the substrate falls on the synchronous belt 74.

[0052] The fourth motor 71 drives the connecting shaft 73 to rotate the overall sprocket 76 and the synchronous wheel 72, and then the third conveying roller 75 rotates under the action of the synchronous chain, so that the synchronous belt 74 can transport the substrate to the vacuum belt 78. Under the action of the negative pressure fan 13, the substrate is stably transported on the outer surface of the vacuum belt 78.

[0053] With the prism strip on the substrate facing upwards, when the substrate moves to the area below the cutting assembly 810, the fourth motor 71 stops, the clamping cylinder 84 on the mounting frame 81 starts, causing the clamping plate 85 to clamp and position the substrate, and the fifth motor 86 drives the adjusting screw 87 to rotate. Under the action of the cutting sprocket 88 and the cutting chain 89, the adjusting screw 87 adjusts the position of the cutting assembly 810, thereby enabling the multi-station laser cutter 8103 to cut the substrate and the prism strip, thereby improving the cutting efficiency. After the cutting is completed, the clamping cylinder 84 resets and the fourth motor 71 starts, causing the cut substrate to move to the baffle frame 82.

[0054] The workers immerse one side of the two sets of cut substrates into the glue bath 9, and then glue the two sets of substrates together. The glued substrates are then placed in the first slot 65 on the first conveyor belt 64. The third motor 61 drives the first conveyor roller 62 to rotate, and the second conveyor roller 63 rotates synchronously under the action of the split sprocket 68 and the split chain 69, so that the second conveyor belt 66 rotates synchronously with the first conveyor belt 64, so that the second slot 67 fits into the first slot 65, thereby positioning the substrate.

[0055] The second motor 53 drives one set of polishing rollers 52 to rotate. Under the action of the double sprocket shaft 54 ​​and the double polishing chain 55, each set of polishing shafts rotates in the same direction, thereby polishing the prism strips on the two sets of substrates. The double polishing improves the processing efficiency of the prisms.

[0056] After polishing, the substrate and prism are pushed out of the first slot 65 by the guide block 12 and fall onto the collection tray 11 so that the staff can collect, sort and move them to the next process.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
