[0020] An embodiment of the present application provides a point glue device 1000, as shown in the drawings, the point glue device 1000 comprises a placement platform 10, a carrying mechanism 20, a point glue mechanism 30 and a visual positioning mechanism 40; the placement platform 10 is used for fixing a light wedge lens assembly 2000; the carrying mechanism 20 is connected with the placement platform 10, and the carrying mechanism 20 is used for driving the placement platform 10 to move in a first direction (for example, the X direction) and a second direction (for example, the Y direction) of the point glue device 1000; the point glue mechanism 30 is connected with the placement platform 10 and is used for dispensing glue on the light wedge lens assembly 2000; and the visual positioning mechanism 40 is connected with the placement platform 10 and is used for positioning the light wedge lens assembly 2000. Figure 1 The point glue device 1000 comprises the placement platform 10, the carrying mechanism 20, the point glue mechanism 30 and the visual positioning mechanism 40; the placement platform 10 is used for fixing the light wedge lens assembly 2000; the carrying mechanism 20 is connected with the placement platform 10, and the carrying mechanism 20 is used for driving the placement platform 10 to move in the first direction (for example, the X direction) and the second direction (for example, the Y direction) of the point glue device 1000; the point glue mechanism 30 is connected with the placement platform 10 and is used for dispensing glue on the light wedge lens assembly 2000; and the visual positioning mechanism 40 is connected with the placement platform 10 and is used for positioning the light wedge lens assembly 2000. Figure 1The placing platform 10 is movable in the X direction (as shown in FIG. 1) and is provided with an upper and lower feeding station and a dispensing station; a dispensing mechanism 30 is arranged beside the conveying mechanism 20 and corresponds to the dispensing station, and the dispensing mechanism 30 comprises a dispensing head 31, which is used to dispense glue at the connection position of the prism lens assembly 2000 when the placing platform 10 is at the dispensing station; a visual positioning mechanism 40 is arranged beside the conveying mechanism 20 and corresponds to the dispensing station, and the visual positioning mechanism 40 is electrically connected to the conveying mechanism 20, and the visual positioning mechanism 40 is used to capture the relative position information of the dispensing head 31 and the connection position of the prism lens assembly 2000. The present application effectively solves the problem of high rejection rate and low production efficiency caused by manual dispensing of the prism lens assembly 2000 in the prior art. The dispensing device 1000 can automatically dispense glue for the prism lens assembly 2000, has higher production efficiency, and can effectively improve the yield.

[0021] Specifically, the dispensing device 1000 realizes automatic transfer of the prism lens assembly 2000 between the feeding and dispensing stations through the conveying mechanism 20, and the relative position information of the dispensing head 31 and the assembly connection position is obtained in real time through the visual positioning mechanism 40, and then the position of the prism lens assembly 2000 is accurately adjusted by the conveying mechanism 20, so that the dispensing head 31 can automatically and accurately complete the dispensing work. Compared with the manual dispensing method, the dispensing device 1000 can automatically dispense glue and has higher positioning accuracy, which can significantly improve the product yield and production efficiency.

[0022] Reference Figure 2 In an embodiment, the conveying mechanism 20 comprises an XY horizontal driving assembly 21 and a rotating driving assembly 22; the XY horizontal driving assembly 21 is connected to the placing platform 10, and is used to drive the placing platform 10 to move in a first direction and a second direction (as shown in FIG. 1). Figure 1 The second direction is perpendicular to the first direction, and the rotating driving assembly 22 is connected to the placing platform 10 and is used to drive the placing platform 10 to rotate when the placing platform 10 is at the dispensing station, so that the prism lens assembly 2000 can rotate relative to the dispensing head 31. In this way, the XY horizontal driving assembly 21 can drive the placing platform 10 to transfer between the upper and lower feeding stations and the dispensing station, and the rotating driving assembly 22 can drive the placing platform 10 to rotate, so that the prism lens assembly 2000 can rotate relative to the dispensing head 31, the dispensing head 31 can dispense glue all around the connection position of the prism lens assembly 2000 in the circumferential direction, and the connection position of the wedge angle piece 220 and the lens 210 in the prism lens assembly 2000 can be completely and uniformly coated with glue, thereby improving the reliability of dispensing glue for the prism lens assembly 2000.

[0023] Specifically, the XY horizontal drive assembly 21 includes a first horizontal drive assembly 211 and a second horizontal drive assembly 212. The first horizontal drive assembly 211 is connected to the placement platform 10 and is used to drive the placement platform 10 to move in a first direction. The second horizontal drive assembly 212 is connected to the placement platform 10 and is used to drive the placement platform 10 to move in a second direction. The first horizontal drive assembly 211 and the second horizontal drive assembly 212 can be linear modules, linear electric cylinders, or other linear motion units, which are not limited here. The rotary drive assembly 22 can be a motor, rotary cylinder, etc., which are not limited here. The connection order of the XY horizontal drive assembly 21, the rotary drive assembly 22, and the placement platform 10 is not limited here. For example, in this embodiment, the rotary drive assembly 22 is installed on the moving part of the XY horizontal drive assembly 21, and the output end of the rotary drive assembly 22 is connected to the placement platform 10.

[0024] Furthermore, the transport mechanism 20 also includes a fine-tuning platform 23, which is used to manually adjust the relative position of the placement platform 10 in a third direction, so as to facilitate the rapid initial alignment between the placement platform 10 and the dispensing station when the optical wedge lens assembly 2000 performs its first dispensing.

[0025] Reference Figure 3 and Figure 5 In one embodiment, the placement platform 10 includes a fixed base 11 and a clamp 12. The fixed base 11 is connected to the conveying mechanism 20, and the clamp 12 is detachably connected to the fixed base 11. The clamp 12 is used to lock or unlock the optical wedge lens assembly 2000. This arrangement facilitates loading and unloading by the operator. The operator can first fix the optical wedge lens assembly 2000 onto the clamp 12, and then place the clamp 12 onto the fixed base 11. On the one hand, this avoids the operator loading and unloading inside the dispensing device 1000. On the other hand, the clamp 12 makes it easier for the operator to pick up the components, improving the efficiency of loading and unloading operations.

[0026] Reference Figure 4 and Figure 6In a specific embodiment, the clamp 12 comprises a seat body 121, a clamping piece 122, and a second elastic piece 123. The seat body 121 is arranged on the fixing seat 11. A limiting groove is arranged on the side of the seat body 121 away from the fixing seat 11. The clamping piece 122 comprises a pressing part 1221, a rotating part 1222, and a pressing part 1223. The rotating part 1222 is rotatably arranged on the seat body 121. The rotating part 1222 is located between the pressing part 1221 and the pressing part 1223. The pressing part 1221 extends into the limiting groove. The pressing part 1221 is used to abut against the optical wedge lens assembly 2000 to lock the optical wedge lens assembly 2000 in the limiting groove. The second elastic piece 123 is arranged on the seat body 121 and connected to the pressing part 1223. When the pressing part 1223 is pressed, the second elastic piece 123 is compressed to store energy. The pressing part 1221 is separated from the limiting groove to unlock the optical wedge lens assembly 2000. In this way, the second elastic piece 123 can drive the pressing part 1223 to rotate the rotating part 1222, so that the pressing part 1221 remains extended into the limiting groove to maintain the locking of the optical wedge lens assembly 2000. When unlocking is needed, the pressing part 1223 is only needed to be pressed. At this time, the second elastic piece 123 is compressed to store energy. The pressing part 1221 is separated from the limiting groove and releases the abutment against the optical wedge lens assembly 2000. The optical wedge lens assembly 2000 is unlocked and can be taken out of the limiting groove. Specifically, the second elastic piece 123 can be a spring, a spring pad, or other elastic elements.

[0027] In addition, in the embodiment, when no force is applied to the pressing part 1223 after the material is replaced, the second elastic piece 123 can also release energy to drive the pressing part 1221 to reset and extend into the limiting groove again, achieving automatic locking without the need for a specific locking step, and the locking is more convenient and efficient.

[0028] Referring to Figure 7 With Figure 8 In an embodiment, the dispensing mechanism 30 comprises a horizontal adjustment assembly 32 and a lifting adjustment assembly 33. The horizontal adjustment assembly 32 is connected to the dispensing head 31 and is used to drive the dispensing head 31 to move in a first direction. The lifting adjustment assembly 33 is connected to the dispensing head 31 and is used to drive the dispensing head 31 to lift in a second direction. The first direction is perpendicular to the second direction. In this way, the horizontal adjustment assembly 32 and the lifting adjustment assembly 33 can adjust the position of the dispensing head 31. When the placement platform 10 is at the dispensing station, the dispensing head 31 and the optical wedge lens assembly 2000 are in the appropriate position, which is conducive to more quickly and efficiently completing the dispensing step.

[0029] Specifically, the horizontal adjusting assembly 32 and the lifting adjusting assembly 33 are both manual screw micro-adjusting slides, the lifting adjusting assembly 33 is arranged on the horizontal adjusting assembly 32, and the glue dispensing head 31 is arranged on the lifting adjusting assembly 33. The relative position between the glue dispensing head 31 and the optical wedge lens assembly 2000 is adjusted by manually rotating the knobs of the horizontal adjusting assembly 32 and the lifting adjusting assembly 33.

[0030] With reference to Figure 7 And Figure 8 In an embodiment, the glue dispensing mechanism 30 further comprises an angle adjusting assembly 34 connected with the glue dispensing head 31, and the angle adjusting assembly 34 is used to adjust the pitch angle of the glue dispensing head 31. In this way, the angle of a specific type of glue dispensing head 31 can be adjusted for different specifications of glue dispensing heads 31, so that the glue dispensing device 1000 can adapt to different glue dispensing requirements and improve the adaptability of the glue dispensing device 1000. Specifically, the angle adjusting assembly 34 is a manual micro-adjusting slide.

[0031] With reference to Figure 8 And Figure 9 In an embodiment, the angle adjusting assembly 34 further comprises a telescopic driving assembly 35, which comprises a horizontal driving member 351, a mounting seat 352, a sliding seat 353, and a first elastic member 354. The horizontal driving member 351 is connected with the mounting seat 352, the sliding seat 353 is slidingly connected to the mounting seat 352, the glue dispensing head 31 is arranged on the sliding seat 353, the horizontal driving member 351 is used to drive the glue dispensing head 31 to move towards or away from the connecting position of the optical wedge lens assembly 2000, and the first elastic member 354 is clamped between the sliding seat 353 and the mounting seat 352 to buffer the glue dispensing head 31 when the glue dispensing head 31 approaches the connecting position of the optical wedge lens assembly 2000. In this way, the horizontal driving member 351 can drive the mounting seat 352 to move, so that after the placement platform 10 reaches the glue dispensing station, the glue dispensing head 31 moves close to the optical wedge lens assembly 2000, preparing for the glue dispensing process, thereby avoiding interference between the placement platform 10 and the glue dispensing head 31 after the placement platform 10 moves to the glue dispensing station. At the same time, if accidental premature contact occurs during the process of the horizontal driving member 351 driving the glue dispensing head 31 to approach the optical wedge lens assembly 2000, the sliding seat 353 can also slide back relative to the mounting seat 352, and the impact energy can be absorbed by the first elastic member 354, thereby effectively protecting the glue dispensing head 31 and the optical wedge lens assembly 2000, and improving the safety of the glue dispensing device 1000 during operation.

[0032] Specifically, the horizontal driving member 351 can be a pneumatic cylinder or an electric cylinder. The first elastic member 354 can be a spring, a spring pad, or other elastic elements.

In this way, the light wedge lens assembly 2000 can be moved to the position where the shooting direction of the second camera 421 intersects with the shooting direction of the first camera 411, the first camera 411 is used to collect the image of the light wedge lens assembly 2000 and the dispensing head 31 from the top view, and the second camera 421 is used to collect the image of the light wedge lens assembly 2000 and the dispensing head 31 from the horizontal view, which can accurately obtain the relative position information between the dispensing head 31 and the light wedge lens assembly 2000, so as to control the carrying mechanism 20 to move accurately and finally position the light wedge lens assembly 2000 at the preset dispensing position, thereby effectively ensuring the dispensing accuracy.

[0034] Specifically, the first shooting assembly 41 further comprises a first lifting assembly 412 connected with the first camera 411, which is used to drive the first camera 411 to lift, so that the first camera 411 can accurately focus and shoot the light wedge lens assembly 2000.

[0035] The second shooting assembly 42 further comprises a light source 422 arranged in the shooting direction of the second camera 421, and the light wedge lens assembly 2000 is located between the light source 422 and the second camera 421. The light source 422 can provide light for the second camera 421 to ensure the clarity of the photograph taken by the second camera 421.

[0036] Referring to Figure 11 In an embodiment, a curing station is further provided, and the dispensing device 1000 further comprises a curing mechanism 50 arranged beside the carrying mechanism 20 and corresponding to the curing station, which is used to cure the light wedge lens assembly 2000 after dispensing. In this way, the arrangement of the curing mechanism 50 can accelerate the setting time of the light wedge lens assembly 2000 after dispensing, ensure the bonding reliability of the light wedge lens assembly 2000, ensure the dispensing quality, and greatly improve the overall production efficiency.

[0037] Specifically, the curing mechanism 50 comprises a second lifting assembly 51 and a heating element 52 connected with the second lifting assembly 51, and the second lifting assembly 51 is used to drive the heating element 52 to lift, so that the heating element 52 can move close to the light wedge lens assembly 2000 after dispensing to cure it. The heating element 52 can be a UV lamp, and the second lifting assembly 51 can be a pneumatic cylinder, an electric cylinder, etc.

[0038] Preferably, the curing mechanism 50 further comprises a cover 53, the heating element 52 is arranged in the cover 53, and the second lifting assembly 51 is capable of moving the cover 53 to cover the optical wedge lens assembly 2000, and then curing the optical wedge lens assembly 2000 by the heating element 52. The cover 53 can avoid the heat dissipation of the heating element 52, and improve the curing rate of the optical wedge lens assembly 2000.

[0039] Referring to Figure 12 In an embodiment, the placing platform 10, the conveying mechanism 20, the dispensing mechanism 30 and the curing mechanism 50 are symmetrically arranged in two groups. In this way, the dispensing device 1000 can simultaneously dispense two optical wedge lens assemblies 2000, further improving the production efficiency.
