[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0018] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a prism bonding fixture, including a fixture base 1; a plurality of support legs 11 are fixedly provided on the bottom outer wall of the fixture base 1, and ear seats 12 are fixedly provided on both sides of the outer wall of the fixture base 1; a plurality of positioning slide grooves 14 are provided inside the mold core mounting groove 13.

[0019] In this embodiment, the support feet 11 allow the fixture base 1 to be placed better on the workbench. The ear seat 12 facilitates the installation of the sliding limit post 6. The mold core 7 is set inside the mold core mounting groove 13, and the side rail 72 on the mold core 7 is inserted into the positioning slide groove 14 to fix the mold core 7 inside the mold core mounting groove 13.

[0020] Please see Figure 1 , Figure 2 and Figure 3 The clamp cover 2 has a handle 21 fixedly installed on its top and perforated lugs 22 fixedly installed at both ends.

[0021] In this embodiment, the operator holds the handle 21 so that the clamp cover 2 can be fitted onto the sliding limit post 6 and can slide laterally above the clamp base 1. The lug 22 is fitted onto the outside of the sliding post 64.

[0022] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 Both the fixture base 1 and the fixture cover 2 have mold core mounting grooves 13 on their opposite outer walls. A replaceable mold core 7 is slidably inserted into the mold core mounting groove 13. A prism is clamped and fixed between the mold cores 7 in the vertical direction. Several side rails 72 are provided on the outer wall of the mold core 7 and inserted into the positioning slide groove 14. A prism slot 71 is provided on the upper part of the mold core 7.

[0023] In this embodiment, a light adhesive is applied to the contact surfaces of the two prisms to bond them together. The prism with the adhesive coating is then placed inside the prism slot 71. Once the two mold cores 7 are snapped together, the prism inside is fixedly clamped.

[0024] Please see Figure 1 , Figure 3 and Figure 4 A flat plate 3 is provided on one side of the fixture base 1. A guide post 15 is fixedly provided on the side wall of the fixture base 1. A through guide hole 32 is provided on the outer wall of the flat plate 3. The guide post 15 is inserted into the guide hole 32. Notches 31 are provided on both sides of the upper part of the flat plate 3. The notches 31 are U-shaped, which improves the aesthetics of the flat plate 3. Vertical plates 33 are provided on both sides of the lower part of the flat plate 3. The vertical plates 33 facilitate the contact between the contact plate 42 and the vertical plate 33, thereby driving the flat plate 3 to move.

[0025] In this embodiment, the guide post 15 is inserted into the guide hole 32 to ensure the stability of the movement of the plate 3 when the plate 3 is moved.

[0026] Please see Figure 1 and Figure 3 Multiple feed clamping modules 4 are provided on one outer wall of the fixture base 1. The feed clamping modules 4 are used to move the flat plate 3 toward the fixture base 1. The feed clamping modules 4 include a support frame 41 fixed on the side wall of the fixture base 1. A screw 43 is inserted into the threaded sleeve at the top of the support frame 41. A contact plate 42 is installed at one end of the screw 43, and a rotating plate 44 is fixedly installed at the other end of the screw 43. A handwheel 45 is provided on one outer wall of the rotating plate 44. By holding the handwheel 45, the rotating plate 44 can be rotated, thereby driving the screw 43 to rotate.

[0027] In this embodiment, the feed clamping module 4 can rotate the screw 43 in the threaded sleeve on the support frame 41, so that the screw 43 drives the contact plate 42 to move horizontally and linearly. This allows the contact plate 42 to move the flat plate 3 towards the fixture base 1, so that the flat plate 3 is tightly attached to one side of the outer surface of the fixture base 1. This can flatten one end of the prism and ensure that one end of the prism is flush with one end of the mold core 7.

[0028] Please see Figure 3 , Figure 4 and Figure 6 Both ends of the clamp base 1 are provided with sliding limit posts 6. The sliding limit posts 6 are used for the clamp top cover 2 to slide laterally and move vertically on the clamp base 1. The sliding limit posts 6 include fixed posts 62 fixed on the top outer wall of the ear seat 12, and the top of the fixed posts 62 is provided with guide rail 63. The top of the fixed posts 62 is provided with sliding posts 64, and the bottom of the sliding posts 64 is provided with a groove 65 that cooperates with the guide rail 63. The upper part of the sliding posts 64 is provided with a through hole 66, and a limit strip 67 is inserted into the through hole 66. After the clamp cover 2 is fastened above the clamp base 1, the operator inserts the limiting strip 67 into the through hole 66 to fix the clamp cover 2 above the clamp base 1. The fixing post 62 is fitted with a limiting sleeve 61 that moves up and down. When the sliding post 64 moves laterally at the top of the fixing post 62, the limiting sleeve 61 is in the lower position. When the limiting sleeve 61 is slid upward, the sliding post 64 can no longer slide laterally above the fixing post 62.

[0029] In this embodiment, the sliding column 64 can slide outside the guide rail 63 at the top of the fixed column 62 through the slot 65 below, thereby allowing the fixture cover 2 to slide laterally above the fixture base 1, and then the fixture cover 2 to drive the mold core 7 below it to slide laterally in sync. Since the contact surface between the two prisms has just been coated with photoresist and the photoresist has not yet cured, the two prisms can move, which makes it easier to position the contact surface of the two prisms laterally.

[0030] Please see Figure 3 , Figure 4and Figure 6 A limiting component 5 is provided on one side of the sliding limiting post 6. The limiting component 5 is used to lock the lateral movement of the sliding limiting post 6. The limiting component 5 includes a support 51 fixed to the end of the ear seat 12, and a sleeve 52 is fixedly installed on the top of the support 51. A sliding rod 53 is inserted into the inside of the sleeve 52, and a pull ring 54 is fixed to the end of the sliding rod 53. A top plate 56 is fixedly provided at one end of the sliding rod 53. A spring 55 is sleeved on the outside of the sliding rod 53, and the spring 55 is located between the top plate 56 and the sleeve 52.

[0031] In this embodiment, through the design of the limiting component 5, when the limiting sleeve 61 is in the upper position, the top plate 56 is in contact with the outer surface of the fixing column 62, that is, the top plate 56 is located below the limiting sleeve 61. When the limiting sleeve 61 is in the lower position, the top plate 56 is in contact with the outer surface of the limiting sleeve 61. The pull ring 54 can drive the sliding rod 53 to move. When the sliding rod 53 is pulled outward, the spring 55 is compressed. When the pull ring 54 is released, the sliding rod 53 is driven to move in the opposite direction under the action of the spring 55.

[0032] The working principle and usage process of this utility model are as follows: First, the operator selects the specifications and shape of the mold core 7 according to the gluing between prisms of different specifications and shapes. The mold core 7 is inserted into the positioning slide groove 14 via the side rail 72, thereby realizing the installation of the mold core 7 inside the fixture base 1 or the fixture cover 2. The optical adhesive is applied between the two prisms, and the overall structure is placed in the prism slot 71 of the fixture base 1. Next, the operator fastens the upper cover 2 of the clamp onto the upper part of the clamp base 1 from top to bottom, so that the upper and lower parts of the mold core 7 are fastened together, and the prism is located inside the cavity between the two mold cores 7. The operator rotates the feed clamping module 4 to move the flat plate 3 toward the fixture base 1, thereby making one end surface of the prism flush with one side surface of the fixture base 1. At this time, the clamp cover 2 is sleeved on the outside of the sliding column 64 through the lug 22 at its end. The operator can make the clamp cover 2 move laterally by holding the handle 21. At this time, the slot 65 at the bottom of the sliding column 64 slides on the guide rail 63, which allows the mold core 7 below the clamp cover 2 to move synchronously for positioning the glued prism. After the clamp cover 2 is moved laterally, the operator adjusts the clamp cover 2 to the center position, then moves the limiting sleeve 61 upward, and the limiting component 5 is reset, thereby realizing the locking of the limiting sleeve 61 between the sliding column 64 and the fixed column 62, and inserting the limiting strip 67 into the through hole 66 to fix the clamp cover 2 in the vertical direction of the sliding column 64. It should be noted that when the limiting sleeve 61 is moved down, the operator first pulls the pull ring 54 to move the sliding rod 53, thereby separating the top plate 56 from the fixed post 62, allowing the limiting sleeve 61 to move to the lowest end. At this time, the pull ring 54 is released, and under the action of the spring 55, the top plate 56 abuts against the outer surface of the limiting sleeve 61, thus realizing the lateral sliding of the sliding post 64 above the fixed post 62.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
