Description

Technical Field

[0001] The present invention relates to the technical field of optical component processing, and more specifically to a special jig for gluing prisms of optical sensors. Background Art

[0002] The optical prism bonding process is one of the processing methods in the optical component bonding process. Its main purpose is to allow optical components to improve the image quality of the optical system, reduce light energy loss, increase imaging clarity, protect the scale surface, ensure the parallelism and thickness difference of the bonded prism, ensure the surface accuracy of the bonded parts, etc., and further optimize the processing flow to meet the design requirements. Optical prism bonding mainly uses optical industry standard glue to perform optical bonding on the surface of optical glass.

[0003] In the production of optical prisms, the gluing process can be either machine-processed or manually processed. In some specific cases, manual processing is still necessary. For example, for some optical prisms with complex shapes or special materials, machine processing may be difficult to achieve the ideal gluing effect, so workers are required to perform manual processing. Manual gluing is to apply optical glue on the gluing surface of one prism, and then align and press the gluing surface of another prism with the former. The gluing process needs to ensure that two or more prisms are aligned with each other, and the optical glue must cover the entire gluing surface. However, the manual gluing error is large, and it is difficult for the prisms to be completely aligned, which can easily lead to low yields. After gluing, workers need to continue pressing for a period of time to wait for the optical glue to solidify, which causes the prism gluing to take too long, reducing production efficiency, and the pressure applied manually during gluing is difficult to maintain consistency, which can easily lead to problems such as insufficient bonding strength of the optical glue, bubble generation, and decreased optical performance. Therefore, it is necessary to propose a special fixture for gluing optical sensor prisms to solve the above problems. Summary of the invention

A wheel column 44 is installed on the top of the clamping frame 42. A positioning mechanism 6 is provided at both ends of the top surface of the side plate 32. The positioning mechanism 6 includes a pressing block 61. The pressing block 61 is slidably connected to the inside of the top end of the side plate 32. A fifth spring 62 is installed inside the top end of the side plate 32, and one end of the fifth spring 62 is installed on the pressing block 61. Two positioning rods 63 are slidably connected to both ends of the top surface of the side plate 32. The inner end of the pressing block 61 and the bottom end of the positioning rod 63 are inclined surfaces that are adapted to and in conflict with each other. A second clamping mechanism 7 is provided in the support leg 43. The second clamping mechanism 7 includes a large hole 71. The large hole 71 is provided at the bottom of the support leg 43. The positioning rod 63 is movably connected to the large hole 71. The upper end of the large hole 71 is connected to a small hole 72. The positioning rod 63 is slidably connected to the small hole 72. The inner wall of the housing 12 is provided with a glue injection mechanism 8, which includes a glue loading chamber 81, which is provided with the glue loading chamber 81 on the inner wall of the housing 12. The upper side of the glue loading chamber 81 is connected with a glue adding tube 82, and the top surface of the glue loading chamber 81 is connected with a glue injection tube 84. The inside of the glue loading chamber 81 is slidably connected with a piston 85, and the top end of the angled rod 83 passes through the bottom surface of the glue loading chamber 81 and is fixedly connected with the piston 85, and the bottom end of the angled rod 83 is slidably connected with the matching groove 391. A guide mechanism 9 is also installed on the base 11, and the guide mechanism 9 includes a guide plate 91. The bottom of the guide plate 91 is fixed to the top surface of the base 11, and a semi-circular inner arc plate 16 is installed on the surface of the guide plate 91. The inner arc plate 16 is concentric with the outer arc plate 17, and the inner side of the inner arc plate 16 and the outer side of the outer arc plate 17 respectively abut against the corresponding pressure block 61. A first guide groove 92 and a second guide groove 93 are provided on the guide plate 91, and the support rod 31 is slidably connected in the second guide groove 93, and the sliding rod 41 is slidably connected in the first guide groove 92. A top plate 94 is fixed on the surface of the guide plate 91, and a shaking groove 95 is provided on the bottom surface of the top plate 94, and the wheel column 44 is slidably connected in the shaking groove 95.

[0020] Further, as attached Figure 7 As shown, the prisms 1110 to be glued are respectively installed in the lower clamping mechanism 3 and the upper clamping mechanism 4, with the glued surfaces facing each other and the glued surfaces being rectangular structures (with attached Figure 7 As shown in the figure, the top surface of the prism 1110 in the lower clamping mechanism 3 is the gluing surface, and the bottom surface of the prism 1110 in the upper clamping mechanism 4 is the gluing surface). The stepper motor 21 inside the bottom plate drives the transmission belt 23 to rotate intermittently through the rotating shaft 22, and the transmission belt 23 drives several groups of lower clamping mechanisms 3 and upper clamping mechanisms 4 installed on its surface to rotate cyclically in the housing 12 (one lower clamping mechanism 3 and one corresponding upper clamping mechanism 4 are a group). When the lower clamping mechanism 3 and the upper clamping mechanism 4 of the same group move to the window 13, the operator can install the prism 1110 to be glued in the V-shaped frame formed by the fixing block 392 and the lifting plate 33 and in the clamping frame 42 respectively, and fix the prism 1110 through the first clamping mechanism 5 and the second clamping mechanism 7.

[0021] Driven by the stepping motor 21, the lower clamping mechanism 3 and the upper clamping mechanism 4 drive the prism 1110 to rotate in the housing 12, first leaving the window 13, the support rod 31 enters the first guide groove 92, and at the same time the slide rod 41 begins to enter the second guide groove 93 (as shown in the attached figure). Figure 6 As shown, the first guide groove 92 is a horizontal slide groove; the second guide groove 93 is composed of two sections of slide grooves, the initial section on the right is a downward inclined groove, and the other section is a horizontal slide groove, and the two sections of the slide grooves are smoothly connected). At the same time, the nozzle of the glue injection tube 84 reaches the upper side of the gluing surface of the prism 1110 in the lower clamping mechanism 3, and the bottom end of the angle rod 83 enters the matching groove 391 of the side plate 32 (as shown in the attached Fig.15 As shown in the figure, the matching groove 391 is an inclined groove with a lower left side and a higher right side). As the transmission belt 23 continues to rotate, the inclined groove section of the second guide groove 93 presses the slide bar 41 downward, and the slide bar 41 slides downward in the corresponding lifting groove 24 (according to the attached Figure 3, the same below), and compress the first spring 25 in the lifting slot 24, the slide bar 41 drives the clamping frame 42 and the prism 1110 therein to move downward; at the same time, the matching slot 391 drives the angle rod 83 to rise, the angle rod 83 pushes the piston 85 in the glue loading chamber 81 to slide upward, and the piston 85 squeezes the optical glue in the glue loading chamber 81 to the gluing surface of the prism 1110 in the lower clamping mechanism 3 through the glue injection tube 84. When the angle rod 83 is separated from the matching slot 391, the glue injection tube 84 stops spraying glue and leaves the gluing surface of the prism 1110, and then the slide bar 41 continues to slide in the oblique slot of the first guide slot 92, and the upper clamping mechanism 4 drives the prism 1110 to continue to descend.

[0022] Then the slide bar 41 drives the upper clamping mechanism 4 down to the bottom of the inclined groove of the first guide groove 92, so that the gluing surface of the prism 1110 in the clamping frame 42 contacts the gluing surface of the prism 1110 in the lower clamping mechanism 3, so that the optical glue is flattened and spreads quickly. While the two prisms 1110 contact each other, the support legs 43 at the bottom of the clamping frame 42 contact the top surface of the side plate 32, so that the positioning rod 63 on the top surface of the side plate 32 is inserted into the large hole 71 in the support legs 43, thereby achieving the initial positioning of the upper clamping mechanism 4 and the lower clamping mechanism 3. The transmission belt 23 drives the slide bar 41 and the support rod 31 to continue sliding in the first guide groove 92 and the second guide groove 93, and then the wheel column 44 at the top of the clamping frame 42 enters the shaking groove 95 in the top plate 94, as shown in the attached figure. Figure 8 As shown, the shaking groove 95 is a wavy structure. When the wheel column 44 slides in the shaking groove 95, it will drive the clamping frame 42 to shake back and forth. The clamping frame 42 slides relative to the sliding rod 41. The clamping frame 42 drives the prism 1110 inside it to reciprocate. The gluing surface thereof slides relative to the gluing surface of the prism 1110 in the lower clamping mechanism 3, and pressure is evenly applied to the optical glue, so that the optical glue is quickly spread out and completely covered on the gluing surface. At the same time, the relative sliding of the gluing surface can make the optical glue evenly distributed, and the pressure can act evenly on every part of the photosynthetic surface, so that the optical glue distribution height at each part of the gluing surface is consistent, and bubbles can be eliminated, thereby improving the bonding strength and quality of the gluing surface.

[0023] After the wheel column 44 disengages from the shaking groove 95, the inner arc plate 16 on the surface of the guide plate 91 and the outer arc plate 17 on the inner side of the shell 12 begin to contact the pressure block 61 on the outer side of the side plate 32 respectively, so that the pressure block 61 slides toward the inside of the side plate 32. The pressure block 61 compresses the fifth spring 62 while pushing the positioning rod 63 to slide. The positioning rod 63 slides into the small hole 72 connected to the large hole 71. Since the diameter of the small hole 72 is the same as the diameter of the positioning rod 63, when the positioning rod 63 is inserted into the small hole 72, the position of the clamping frame 42 can be immediately adjusted so that the clamping frame 42 is accurately aligned with the lower clamping mechanism 3, so that the gluing surfaces of the two prisms 1110 are accurately bonded, and the inner arc plate 16 and the outer arc plate 17 continue to squeeze the pressure block 61. Therefore, the upper clamping mechanism 4 and the lower clamping mechanism 3 can maintain accurate alignment for a long time during the movement, so that the gluing surfaces of the prism 1110 have sufficient time to be bonded. As the transmission belt 23 rotates, the sliding bar 41 and the support bar 31 eventually disengage from the first guide groove 92 and the second guide groove 93, and the pressure block 61 is no longer squeezed by the outer arc plate 17 and the inner arc plate 16. After the sliding bar 41 disengages from the first guide groove 92, under the elastic force of the first spring 25, the sliding bar 41 drives the clamping frame 42 to rise rapidly, the sliding bar 41 returns to the top of the lifting groove 24, and the positioning rod 63 is pulled out of the small hole 72. Since the prism 1110 is bonded together by optical glue, the prism 1110 is separated from the clamping frame 42 when the clamping frame 42 rises; after the pressure is lost, the fifth spring 62 immediately pushes the pressure block 61 to pop out from the side plate 32, and the positioning rod 63 drops and resets, and then the transmission belt 23 continues to drive the upper clamping mechanism 4 and the lower clamping mechanism 3 to move until the bonded prism 1110 leaves the lower clamping mechanism 3.

The second spring 54 abuts against the inside of the side plate 32, the locking rod 55 is slidably connected to the inside of the side plate 32, the third spring 56 is sleeved on the locking rod 55, a fourth spring 57 is installed inside one end of the locking rod 55, a lever 58 is slidably connected to one end of the locking rod 55, the lever 58 is installed on the top of the fourth spring 57, and the push rod 39 abuts against the lever 58, the other end of the locking rod 55 and the side of the first rack 53 are provided with locking teeth 59, and the locking teeth 59 on the locking rod 55 are engaged with the locking teeth 59 on the first rack 53.

[0028] A sixth spring 73 is installed in the small hole 72, and a lifting rod 74 is slidably connected in the small hole 72. The bottom end of the lifting rod 74 abuts against the bottom end of the sixth spring 73, and the positioning rod 63 abuts against the bottom end of the lifting rod 74. The limiting rod 75 is slidably connected to the interior of the clamping frame 42. A wedge block 76 is fixed to one end of the limiting rod 75, and the top of the lifting rod 74 is adapted to the wedge block 76. The second rack 77 is slidably connected to the interior of the clamping frame 42, and the second rack 77 is meshed with the second gear 52 inside the clamping frame 42. Locking teeth 59 are provided on the side of the second rack 77 and the other end of the limiting rod 75, and the locking teeth 59 on the second rack 77 are engaged with the locking teeth 59 on the limiting rod 75.

[0029] The window 13 can expose the upper clamping mechanism 4 and the lower clamping mechanism 3 , making it convenient for the operator to install the prism 1110 .

[0030] After the prism 1110 is placed in the V-shaped frame and the clamping frame 42 in the lower clamping mechanism 3, the operator presses the first rack 53 on the top surface of the side plate 32 and the second rack 77 on the top surface of the clamping frame 42, and the first rack 53 slides downward into the side plate 32 (as shown in the attached figure). Fig.11, the same below), compresses the second spring 54, and drives the second gear 52 to rotate, thereby pushing the clamping plate 51 from the side plate 32 toward (the clamping plate 51 is composed of a plate and a stud, and the stud is meshingly connected with the corresponding second gear 52. When the second gear 52 rotates, the plate is driven by the stud to slide out from the inner side of the side plate 32 and contact the side of the prism 1110), squeezing the side of the prism 1110, thereby fixing the prism 1110; similarly, pressing the second rack 77, the second rack 77 slides into the clamping frame 42, compressing the second spring 54 at the bottom thereof, and driving the second gear 52 inside the clamping frame 42 to rotate, and the second gear 52 drives its matching clamping plate 51 to slide out of the clamping frame 42, squeezing the side of the prism 1110 in the clamping frame 42, thereby fixing the prism 1110. Locking teeth 59 are provided on the sides of the first rack 53 and the second rack 77, and when the first rack 53 and the second rack 77 slide downward, the locking teeth 59 on the locking rod 55 will not prevent the first rack 53 from sliding downward, and the locking teeth 59 on the limiting rod 75 will not prevent the second rack 77 from sliding downward.

[0031] When the positioning rod 63 enters the small hole 72, it will push the lifting rod 74 upward, which compresses the sixth spring 73 and drives the limiting rod 75 to slide by squeezing the wedge block 76. When the limiting rod 75 slides, it not only compresses the third spring 56 thereon, but also drives the locking tooth 59 at its end to separate from the locking tooth 59 on the side of the second rack 77, thereby releasing the lock of the second rack 77. The second spring 54 at the bottom of the second rack 77 is reset to push the second rack 77 upward. The second rack 77 drives the second gear 52 inside the clamping frame 42 to reverse, thereby retracting the clamping plate 51. The clamping plate 51 no longer fixes the prism 1110, and the prism 1110 can be detached from the clamping frame 42. Therefore, when the sliding rod 41 is detached After leaving the first guide groove 92, the clamping frame 42 can slide upward immediately following the slide bar 41 without driving the prism 1110 to rise together; after the slide bar 41 leaves the first guide groove 92, it immediately rises to the top of the lifting groove 24 to expose the prism 1110 bonded together (the prism 1110 bonded together is in the lower clamping mechanism 3), and at this time it just reaches the area where the ultraviolet lamp 19 is installed in the shell 12, and the ultraviolet lamp 19 can assist in the curing of the optical glue and speed up the bonding efficiency; after the lower clamping mechanism 3 leaves the irradiation area of ​​the ultraviolet lamp 19, the first gear 38 on the surface of the side plate 32 is meshed and connected with the unloading tooth plate 191 inside the shell 12, and the unloading tooth plate 191 drives the first gear 38 to rotate, and the first gear 38 drives The inner shaft 36 rotates, and the long strip 37 on the inner shaft 36 slides in the adjustment groove 35 inside the rotating drum 34. Due to the buffering of the adjustment groove 35, the first gear 38 first drives the inner shaft 36 to rotate in the rotating drum 34 (the inner shaft 36 and the side plate 32 are rotationally connected by a torsion spring, and the rotation of the inner shaft 36 will cause the torsion spring to tighten). In this process, the inner shaft 36 drives the push rod 39 to swing. During the swinging process of the push rod 39, the locking rod 55 is pushed by the lever 58. The locking rod 55 slides and compresses the third spring 56, and at the same time, the locking teeth 59 at its end are separated from the locking teeth 59 on the side of the first rack 53, thereby releasing the lock of the first rack 53. Under the push of the second spring 54, the first rack 53 slides upward and drives the second rack 53 to slide upward. The wheel 52 flips over, so that the clamping plate 51 is retracted, and the clamping plate 51 fixes the prism 1110. After the release, the long strip 37 on the inner shaft 36 just contacts the end of the adjusting slot 35, thereby driving the rotating drum 34 to rotate, and the rotating drum 34 drives the lifting plate 33 to rotate, and the lifting plate 33 drives the prism 1110 to flip, thereby transferring the prism 1110 to the support plate 15, and the support plate 15 is rotatably connected to the recovery box 14 through a torsion spring. The torsion spring can make the support plate 15 have a buffering effect when it is compressed, reducing the impact when the prism 1110 falls, and then the support plate 15 rotates into the recovery box 14, and the prism 1110 is smoothly sent into the recovery box 14 to avoid damage to the prism 1110 due to collision, and then under the action of the torsion spring, the support plate 5 is reset.After the first gear 38 disengages from the unloading tooth plate 191, the torsion spring on the inner shaft 36 causes the inner shaft 36 to reverse, and at the same time, the inner shaft 36 drives the push rod 39 to reverse, and the push rod 39 squeezes the shifting post 58 on the locking rod 55, and the shifting post 58 slides downward, compressing the fourth spring 57 and allowing the push rod 39 to reset smoothly; then the inner shaft 36 drives the rotating drum 34 to reverse through the cooperation of the long strip 37 and the adjusting groove 35, and the rotating drum 34 drives the lifting plate 33 to reset.

[0032] Example 3: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 17 A seventh spring 88 is installed inside the glue loading bin 81 , and the piston 85 abuts against the seventh spring 88 . A first one-way valve 86 is installed in the glue adding tube 82 , and a second one-way valve 87 is installed in the glue injection tube 84 .

[0033] A glue removal mechanism 10 is installed inside the clamping frame 42, and the glue removal mechanism 10 includes a guide rod 101, which is installed inside the two ends of the clamping frame 42, one end of the guide rod 101 is sleeved with an eighth spring 102, and one end of the eighth spring 102 is installed inside the clamping frame 42, a wiper block 103 is slidably connected to the guide rod 101, and the other end of the eighth spring 102 is installed on one side of the wiper block 103, and a driving plate 104 is fixed to the other side of the wiper block 103, and the driving plates 104 respectively resist the corresponding paddle plates 18.

[0034] During the upward sliding process of the piston 85, not only the seventh spring 88 is compressed, but also the pressure generated causes the first one-way valve 86 in the glue adding tube 82 to close, the second one-way valve 87 in the glue injection tube 84 to open, and the optical glue in the glue loading chamber 81 flows out from the glue injection tube 84, and in conjunction with the uniform movement of the prism 1110, the glue injection tube 84 applies the optical glue in the form of long strips 37 on the bonding surface of the prism 1110. After the angle rod 83 is separated from the matching groove 391, the seventh spring 88 in the glue loading chamber 81 pushes the piston 85 downward, and the suction force causes the first one-way valve 86 in the glue adding tube 82 to open, and the second one-way valve 87 in the glue injection tube 84 to close. The suction force also causes the external optical glue to enter the glue loading chamber 81 through the glue adding tube 82. The stroke of the piston 85 can ensure that the optical glue enters the glue loading chamber 81 quantitatively each time, thereby ensuring that the long strips 37 of optical glue squeezed out from the glue injection tube 84 are equal each time, and further ensuring that the quality of the optical glue applied on each bonding surface is consistent.

[0035] Since the bonding surface of the prism 1110 is rectangular, when the optical glue is squeezed on the bonding surface, the optical glue will overflow from the long side of the bonding surface. In order to remove the overflowed glue in time to avoid affecting the quality of the prism 1110, a glue removal mechanism 10 is provided at the bottom of the clamping frame 42. When the wheel column 44 disengages from the shaking groove 95 and the inner arc plate 16 and the outer arc plate 17 begin to contact the pressure block 61, the paddle plate 18 on the inner arc plate 16 and the outer arc plate 17 just contacts the driving plate 104. At the same time, the upper clamping mechanism 4 and the lower clamping mechanism 3 begin to turn (the upper clamping mechanism 4 and the lower clamping mechanism 3 reach the end of the transmission belt 23) and the paddle plate 18 contacts the driving plate 104, thereby driving the wiper 103 to slide on the guide rod 101. During the sliding process of the wiper 103, the eighth spring 102 is lengthened, and at the same time, the splicing of the prism 1110 is wiped to remove the overflowed optical glue. As the transmission belt 23 drives the upper clamping mechanism 4 to rotate, the driving plate 104 gradually shifts relative to the paddle plate 18. When the wiper 103 slides to the other end of the clamping frame 42, the paddle plate 18 just no longer contacts the driving plate 104, and the eighth spring 102 will pull the wiper 103 back along the guide rod 101, thereby resetting.
