[0004] The main objective of this invention is to provide a prism assembly tooling that addresses the issues of numerous operation steps affecting assembly efficiency and product assembly quality.

[0005] To achieve the above objectives, this invention proposes a prism assembly fixture, comprising a support frame, a positioning base plate, a cover plate assembly, a drive assembly, and a flipping drive component. The positioning base plate is rotatably connected to the support frame and has a positioning groove and an injection hole disposed on the bottom wall of the positioning groove. The positioning groove is used to place the optical engine body and the prism. The cover plate assembly includes two linked cover plates, which are rotatably connected to the positioning base plate. The drive assembly is connected to the positioning base plate, and its output end is connected to either of the cover plates to drive the two cover plates to rotate and open or close the positioning groove. The flipping drive component is connected to the support frame, and its output end is connected to the positioning base plate. The flipping drive component is used to drive the positioning base plate to rotate.

[0006] In one embodiment, the two cover plates are a first cover plate and a second cover plate, and the first cover plate is located between the second cover plate and the positioning base plate; the driving assembly includes a linear drive and a connecting rod, the linear drive is connected to the positioning base plate, the connecting rod is rotatably connected to the positioning base plate, the first end of the connecting rod is movably connected to the output end of the linear drive, and the second end of the connecting rod is slidably connected to the second cover plate, the linear drive is used to drive the connecting rod to rotate and push the second cover plate to rotate.

[0007] In one embodiment, the output end of the linear drive is connected to a push block, the push block having a first groove extending in a vertical direction, and the first end of the connecting rod is slidably disposed in the first groove.

[0008] In one embodiment, a second groove is provided on the second cover plate, and the second end of the connecting rod is slidably disposed in the second groove. When the second cover plate is closed on the positioning groove, the second end of the connecting rod abuts against the bottom wall of the second groove.

[0009] In one embodiment, the number of connecting rods is two, and the driving assembly further includes a transmission rod, the two ends of which are respectively connected to the first ends of the two connecting rods, and the transmission rod is slidably disposed in the first groove.

[0010] In one embodiment, of the two cover plates, one cover plate is provided with a connecting plate and a third sliding groove is formed on the connecting plate; the other cover plate is provided with a transmission protrusion, which is slidably disposed in the third sliding groove.

[0011] In one embodiment, a connecting seat is provided on the positioning base plate, and the prism assembly tooling further includes a pivot, which passes through the two cover plates and the connecting seat, and the pivot is rotatably connected to the connecting seat and the two cover plates.

[0012] In one embodiment, the prism assembly further includes a locking component for locking the two cover plates to the positioning base plate when both cover plates are closed in the positioning groove.

[0013] In one embodiment, both cover plates are provided with locking grooves, and the two locking grooves are staggered; the locking assembly includes a mounting base and two locking hooks, and the two locking hooks are provided in a one-to-one correspondence with the two locking grooves; the mounting base is disposed on the positioning base plate, the locking hooks are rotatably connected to the mounting base, and each locking hook is connected to the mounting base by an elastic element, one end of the locking hook is bent in the direction of the flipping drive to form a hook-shaped part, and the bottom of the hook-shaped part is used to cooperate with the corresponding locking groove to lock the corresponding cover plate.

[0014] In one embodiment, the prism assembly further includes an unlocking component, which includes a lifting drive and two pressure plates, each pressure plate corresponding to one of the two locking hooks; the side of the locking hook facing away from the flipping drive forms a stepped surface, and the lifting drive drives the pressure plate to move so that the pressure plate abuts against the corresponding stepped surface and pushes the locking hook to rotate to unlock the corresponding cover plate.

[0015] In this invention, during prism assembly, the optical engine body is placed in the positioning slot, and then the prism is placed in the corresponding position on the optical engine body. A drive assembly drives one cover plate to rotate counter-clockwise, which in turn drives the other cover plate to rotate counter-clockwise until both cover plates are closed in the positioning slot. At this point, the two cover plates cooperate with the positioning base plate to achieve complete positioning of the optical engine body and the prism, preventing misalignment. A flip drive is used to flip the positioning base plate to the adhesive curing surface (with the adhesive injection hole facing upwards). Adhesive is applied to the injection hole to cure the connection between the optical engine body and the prism. After curing, the flip drive again drives the positioning base plate to flip back to the material receiving surface (with the positioning slot facing upwards). The drive assembly moves in the opposite direction, driving the two cover plates to open the positioning slot. The cured optical engine body and prism are then removed for a new round of assembly. This invention simply requires placing the main body in the corresponding position of the tooling and placing the prism in the corresponding position of the main body. The driving components and the flipping driving components rely on the equipment signal transmission to automatically perform subsequent actions, realizing the opening and closing of the cover plate and the flipping of the positioning base plate. The operation is stable, avoiding human operation errors, improving product consistency, reducing quality risks, and improving processing efficiency. Attached Figure Description

If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0030] This invention provides a prism assembly fixture. A positioning base plate and a cover plate assembly work together to position the optical engine body and the prism. Then, the positioning base plate is rotated so that the glue injection hole faces upwards, and glue is injected into the hole to fix the optical engine body and the prism. Relying on the fixture's own signal transmission, the drive assembly and the flip drive component are triggered to perform corresponding actions, ensuring stable operation, avoiding errors, reducing quality risks, and improving processing efficiency.

[0031] like Figures 1 to 3As shown, in one embodiment of the present invention, the prism assembly fixture 100 includes a support frame 1, a positioning base plate 2, a cover plate assembly 3, a drive assembly 4, and a flipping drive component 5. The positioning base plate 2 is rotatably connected to the support frame 1. The positioning base plate 2 has a positioning groove 21 and an injection hole 22 disposed on the bottom wall of the positioning groove 21. The positioning groove 21 is used to place the optical engine body and the prism. The cover plate assembly 3 includes two linked cover plates 31, both of which are rotatably connected to the positioning base plate 2. The drive assembly 4 is connected to the positioning base plate 2, and the output end of the drive assembly 4 is connected to any one of the cover plates 31 to drive the two cover plates 31 to rotate to open or close the positioning groove 21. The flipping drive component 5 is connected to the support frame 1, and the output end of the flipping drive component 5 is connected to the positioning base plate 2. The flipping drive component 5 is used to drive the positioning base plate 2 to rotate.

[0032] In the above embodiments, during prism assembly, the optical engine body is placed in the positioning groove 21, and then the prism is placed in the corresponding position on the optical engine body. The drive assembly 4 drives one of the cover plates 31 to rotate counterclockwise, which in turn drives the other cover plate 31 to rotate counterclockwise until both cover plates 31 are closed in the positioning groove 21. At this point, the two cover plates 31 can cooperate with the positioning base plate 2 to achieve complete positioning of the optical engine body and the prism, preventing misalignment. The flip drive 5 is used to flip the positioning base plate 2 to the adhesive curing surface (with the adhesive injection hole 22 facing upwards). Adhesive can be applied to the adhesive injection hole 22 to cure the connection between the optical engine body and the prism. After curing, the flip drive 5 drives the positioning base plate 2 to flip back to the material receiving surface (with the positioning groove 21 facing upwards), and the drive assembly 4 moves in the opposite direction, driving the two cover plates 31 to open the positioning groove 21. The cured optical engine body and prism are then removed for a new round of assembly. This invention only requires placing the main body in the corresponding position of the tooling and placing the prism in the corresponding position of the main body. The drive component 4 and the flip drive component 5 rely on the equipment signal transmission to automatically perform subsequent actions, realize the opening and closing of the cover plate 31 and the flipping of the positioning base plate 2, and ensure stable operation, avoid human operation errors, improve product consistency, reduce quality risks, and improve processing efficiency.

[0033] In one embodiment, the two cover plates 31 are a first cover plate 31a and a second cover plate 31b, with the first cover plate 31a located between the second cover plate 31b and the positioning base plate 2. The driving assembly 4 includes a linear drive member 41 and a connecting rod 42. The linear drive member 41 is connected to the positioning base plate 2, and the connecting rod 42 is rotatably connected to the positioning base plate 2. The first end of the connecting rod 42 is movably connected to the output end of the linear drive member 41, and the second end of the connecting rod 42 is slidably connected to the second cover plate 31b. The linear drive member 41 is used to drive the connecting rod 42 to rotate and push the second cover plate 31b to rotate. The second cover plate 31b, the first cover plate 31a, and the positioning base plate 2 are arranged sequentially from top to bottom. The driving assembly 4 directly drives the second cover plate 31b to rotate through the connecting rod 42, and drives the first cover plate 31a to rotate through the linkage between the second cover plate 31b and the first cover plate 31a. Thus, when the second cover plate 31b rotates to its position, it can press on the first cover plate 31a, ensuring that both cover plates 31 are covered in the positioning groove 21.

[0034] The connecting rod 42 is rotatably connected to the positioning base plate 2. The connecting rod 42 can be located on the left or right sides of the positioning base plate 2, or the positioning base plate 2 can have a clearance groove for the connection to pass through. At the same time, the clearance groove needs to have a certain gap to avoid interference between the connecting rod 42 and the positioning base plate 2 when rotating. The linear drive component 41 is a cylinder. The cylinder pushes the bottom end of the connecting rod 42 to rotate, while the top end of the connecting rod 42 rotates around the rotatable connection between the connecting rod 42 and the positioning base plate 2. When the connecting rod 42 rotates to be perpendicular to the positioning base plate 2, that is, when the connecting rod 42 rotates to be vertical, the second cover plate 31b opens to the maximum angle. At this time, the first cover plate 31a should also be completely disengaged from the positioning groove 21 to facilitate the placement and removal of the optical engine body and the prism.

[0035] In the example of the above embodiment 1, the output end of the linear drive 41 is connected to a push block 43. The push block 43 has a first groove 431 extending in the vertical direction, and the first end of the connecting rod 42 is slidably disposed in the first groove 431. While the linear drive 41 pushes the connecting rod 42 for transmission, the first end of the connecting rod 42 simultaneously slides in the first groove 431, thereby converting the linear motion of the linear drive 41 into the rotation of the connecting rod 42.

[0036] In other examples, a groove can be provided on the connecting rod 42, and the output end of the linear drive 41 can be slidably disposed in the groove on the connecting rod 42. Alternatively, the output end of the linear drive 41 can be connected to the connecting rod 42 via a transmission rod 44, with both ends of the transmission rod 44 being rotatably connected to the output end of the linear drive 41 and the connecting rod 42, respectively.

[0037] In another example of the above embodiment, a second sliding groove 311 is provided on the second cover plate 31b, and the second end of the connecting rod 42 is slidably disposed in the second sliding groove 311. When the second cover plate 31b is closed on the positioning groove 21, the second end of the connecting rod 42 abuts against the bottom wall of the second sliding groove 311. Since the rotation center of the connecting rod 42 is not consistent with the rotation center of the second cover plate 31b, the second sliding groove 311 is provided to absorb the error and prevent the second cover plate 31b from jamming during rotation.

[0038] In a preferred example, when the second cover plate 31b is closed in the positioning groove 21, the second slide groove 311 is horizontally set, and the second end of the connecting rod 42 abuts against the bottom wall of the second slide groove 311. Thus, when the second cover plate 31b rotates into place, it can press on the first cover plate 31a, ensuring that both cover plates 31 are closed in the positioning groove 21.

[0039] In another example of the above embodiments, there are two connecting rods 42, and the drive assembly 4 also includes a transmission rod 44. The two ends of the transmission rod 44 are respectively connected to the first ends of the two connecting rods 42, and the transmission rod 44 is slidably disposed in the first slide groove 431. That is, connecting rods 42 are provided on both the left and right sides of the second cover plate 31b. Thus, the output end of the linear drive member 41 pushes the transmission rod 44 to move, and the transmission rod 44 synchronously pushes the two connecting rods 42 to rotate. As a result, both the left and right sides of the second cover plate 31b have thrust from the connecting rods 42, so that the forces on the left and right sides of the second cover plate 31b are consistent, avoiding the second cover plate 31b from twisting due to its own weight, and reducing wear at the rotation center of the second cover plate 31b.

[0040] To better ensure the stability of the rotation of the second cover plate 31b, the push block 43 should have a certain width to increase the contact surface between the push block 43 and the transmission rod 44, and avoid the phenomenon of asynchronous rotation of the two connecting rods 42 caused by the tilt of the transmission rod 44.

[0041] In one embodiment, of the two cover plates 31, one cover plate 31 is provided with a connecting plate 61, and the connecting plate 61 has a third sliding groove 611; the other cover plate 31 is provided with a transmission protrusion 62, which is slidably disposed within the third sliding groove 611. The transmission protrusion 62 and the third sliding groove 611 cooperate to form a linkage structure. When the second cover plate 31b rotates clockwise, within a certain angle range, when the second cover plate 31b rotates clockwise, the transmission protrusion 62 slides within the third sliding groove 611, while the first cover plate 31a remains stationary; when the second cover plate 31b continues to rotate clockwise, the transmission protrusion 62 reaches the end of the third sliding groove 611 and drives the first cover plate 31a to rotate clockwise through the connecting plate 61. Conversely, when the second cover plate 31b rotates counterclockwise, the transmission protrusion 62 slides in the third slide groove 611, the first cover plate 31a remains stationary, and the second cover plate 31b continues to rotate counterclockwise so that the transmission protrusion 62 reaches the end of the third slide groove 611 and drives the first cover plate 31a to rotate counterclockwise through the connecting plate 61 until the first cover plate 31a and the second cover plate 31b are closed in the positioning groove 21.

[0042] In other embodiments, a spring can be provided between the transmission protrusion 62 and the end of the third slide groove 611. Thus, when the second cover plate 31b rotates clockwise, the movement of the first cover plate 31a remains unchanged; however, when the second cover plate 31b rotates counterclockwise, under the action of the spring, the first cover plate 31a first rotates counterclockwise with the second cover plate 31b until the first cover plate 31a closes in the positioning groove 21. Then, the second cover plate 31b rotates counterclockwise to compress the spring until the second cover plate 31b also closes in the positioning groove 21. This allows the two cover plates 31 to open and close sequentially, facilitating observation of the positioning effect of the optical engine body and the prism.

[0043] In one embodiment, a connecting seat 631 is provided on the positioning base plate 2. The prism assembly fixture 100 also includes a pivot 632, which passes through the two cover plates 31 and the connecting seat 631, and is rotatably connected to the connecting seat 631 and the two cover plates 31. Both cover plates 31 are rotatably connected to the connecting seat 631 via the pivot 632, so that the rotation axes of the two cover plates 31 are consistent, which facilitates the determination of the movement trajectory of the first cover plate 31a and the second cover plate 31b. Since the shape of the third slide 611 needs to be determined based on the trajectory of the first cover plate 31a and the second cover plate 31b, and since the movement trajectories of the first cover plate 31a and the second cover plate 31b are consistent, it can be easily known that the shape of the third slide 611 is an arc segment centered on the pivot 632. The positioning seat and the positioning base plate 2 can be an integral structure.

[0044] In one embodiment, the prism assembly fixture 100 further includes a locking component 7, which locks the two cover plates 31 to the positioning base plate 2 when both cover plates 31 are closed in the positioning groove 21. When both cover plates 31 are closed in the positioning groove 21, the locking component 7 locks the two cover plates 31, ensuring that the two cover plates 31 can be stably pressed against the optical engine body and the prism during the dispensing and curing process, preventing displacement. Furthermore, the locking component 7 applies a force towards the positioning base plate 2 to the first cover plate 31a and the second cover plate 31b, preventing the connecting rod 42 from deforming under prolonged stress, thereby ensuring the consistency of the movement trajectory of the first cover plate 31a and the second cover plate 31b.

[0045] In the example of the above embodiment 1, both cover plates 31 are provided with locking grooves 312, and the two locking grooves 312 are staggered; the locking assembly 7 includes a mounting base 71 and two locking hooks 72, and the two locking hooks 72 are provided in a one-to-one correspondence with the two locking grooves 312; the mounting base 71 is provided on the positioning base plate 2, the locking hooks 72 are rotatably connected to the mounting base 71, and each locking hook 72 is connected to the mounting base 71 by an elastic element, one end of the locking hook 72 is bent toward the direction of the flipping drive 5 to form a hook-shaped part 721, and the bottom of the hook-shaped part 721 is used to cooperate with the corresponding locking groove 312 to lock the corresponding cover plate 31. When the two locking hooks 72 rotate counterclockwise, the two cover plates 31 can move to close into the positioning grooves 21. Under the action of the elastic element, the two locking hooks 72 rotate clockwise, causing the hook-shaped parts 721 of the two locking hooks 72 to press against the bottom wall of the locking groove 312, thereby stopping the clockwise rotation of the two cover plates 31 and locking the two cover plates 31. The staggered arrangement of the two locking grooves 312, that is, the staggered arrangement of the two locking hooks 72, can avoid mutual interference.

[0046] Specifically, the hook-shaped part 721 has a guide slope on the side away from the positioning base plate 2. The guide slope is inclined downward in the direction close to the flipping drive member 5. As a result, the two cover plates 31 rotate clockwise, and the edges of the two cover plates 31 press against the guide slope, causing the locking hook 72 to rotate counterclockwise. Thus, the two cover plates 31 can move to cover the positioning groove 21, and the two locking hooks 72 rotate clockwise under the action of the elastic member. Thus, the locking assembly 7 can automatically lock as the two cover plates 31 rotate.

[0047] Based on the above example, please refer to [see also...] Figure 4 The prism assembly fixture 100 also includes an unlocking component 8, which comprises a lifting drive 81 and two pressure plates 82. The two pressure plates 82 are correspondingly positioned with two locking hooks 72. The side of the locking hook 72 facing away from the flipping drive 5 forms a stepped surface 722. The lifting drive 81 drives the pressure plates 82 to move, causing them to abut against the corresponding stepped surface 722 and push the locking hooks 72 to rotate, thereby unlocking the corresponding cover plates 31. The unlocking component 8 unlocks the corresponding cover plates 31 automatically by pushing the corresponding locking hooks 72 to rotate through the two pressure plates 82.
