DETAILED DESCRIPTION
[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0023] Embodiment 1: An automatic dispensing pad for producing an optical lens, such as Figure 1-6As shown, it includes a lower bottom plate 1, an upper top plate 2, a receiving groove 21, a guide rod 3, a sliding plate 4, a connecting block 41, a bracket 5, a guide rail 6, a slider 7 and a connecting rod 8. The guide rods 3 are symmetrically welded on the front and rear sides and the left and right sides of the bottom of the upper top plate 2. The upper top plate 2 is slidably connected to the lower bottom plate 1 through the guide rods 3. A receiving groove 21 is opened on the upper part of the upper top plate 2. A sliding plate 4 that can move smoothly is slidably provided inside the receiving groove 21. A bracket 5 that carries an optical lens is fixed on the top of the sliding plate 4. Guide rails 6 that play a guiding role are installed on the front side of the middle inner side of the lower bottom plate 1 and the right side of the middle inner side of the lower bottom plate 1. The two guide rails 6 are crossed and They are installed and placed in a state without interfering with each other, and the outer left side of the front guide rail 6 and the outer rear side of the right guide rail 6 are both slidably and rotatably connected with sliders 7. The two sliders 7 are installed and placed diagonally inside the lower base plate 1 and in a state without interfering with each other. Connecting rods 8 are slidably provided on the inner sides of the two sliders 7. The left front side of the bottom of the sliding plate 4 and the right rear side of the bottom of the sliding plate 4 are fixedly connected with connecting blocks 41. The upper part of the left front connecting rod 8 is rotatably connected to the left front connecting block 41 of the bottom of the sliding plate 4, and the upper part of the right rear connecting rod 8 is rotatably connected to the right rear connecting block 41 of the bottom of the sliding plate 4. The friction coefficient between the slider 7 and the guide rail 6 and the connecting rod 8 is small, which is convenient for movement.
[0024] Working principle: When assembling an optical lens, there are usually one or more locations that require glue dispensing. When some optical lenses need to be glued at multiple locations, first align the location that requires glue dispensing with the glue dispensing machine above. After the glue dispensing work at the first glue point is completed, the optical lens needs to be moved to align the second location that requires glue dispensing with the glue dispensing machine. When using the glue dispensing pad of the utility model, the lower base plate 1 is installed at the lower position opposite to the glue dispensing machine, and then the upper top plate 2 is placed on the lower base plate 1 through the guide rail 6, and then The optical lens is placed in the support block 5 on the sliding plate 4. At this time, the optical lens can be controlled to align with the dispensing machine by moving the sliding plate 4 in the receiving groove 21. When the sliding plate 4 moves, the sliding plate 4 drives the fixed block 14 at the bottom to move. The two fixed blocks 14 drive the connected connecting rod 8 to slide on the guide rail 6 through the slider 7. The slider 7 and the connecting rod 8 will adjust the position and state as the sliding plate 4 moves (for example: when the sliding plate 4 moves to the right rear side in the receiving groove 21, the fixed block 14 on the left front side drives the connecting rod 8 on the left front side The sliding block on the left front side translates to the right side along with the inner connecting rod 8, and the connecting rod 8 on the left front side will bring the sliding block 7 to rotate forward a certain angle while translating to the right. Similarly, the connecting rod 8 and the sliding block 7 on the right rear side will adjust their positions and states along with the movement of the sliding plate 4 and the right rear side fixed block 14. The sliding plate 4 drives the support block 5 and the movement inside the support block 5. When the glue point position of the optical lens placed on the support block 5 is aligned with the glue dispenser, the glue dispenser is controlled to dispense glue to the lens. After the glue dispensing work of one glue point is completed, the sliding plate continues to be moved. 4 changes the position of the optical lens on the support block 5, and glues the multiple glue points on the optical lens in turn. When the glue is being dispensed, the connecting rod 8 and the guide rail 6 are arranged on the lower bottom plate 1 to cooperate with the sliding plate 4, so that when the sliding plate 4 moves, the optical lens in the support block 5 can be maintained in a horizontal position, and the lens can be moved to the desired position smoothly and quickly, avoiding the need to move and adjust the position of the lens by hand during glue dispensing, facilitating the operation while reducing the impact on the glue dispensing quality. After the glue dispensing is completed, the optical lens is taken out.
[0025] Embodiment 2: Based on embodiment 1, Figure 1-6 As shown, it also includes a guide groove 10, two guide grooves 10 are opened on the sliding plate 4, and the inner sides of the guide grooves 10 are slidably connected to the sliding frames 11, and the inner sides of the upper parts of the sliding frames 11 are connected to the clamping blocks 12 for clamping the optical lens, and the clamping blocks 12 are made of a colloid material that causes less damage to the lens barrel. A fixed block 14 is welded to the bottom of the sliding plate 4, and a gear 16 is rotatably provided on the outer side of the upper part of the fixed block 14. Racks 13 are connected to the outer sides of the lower part of the sliding frame 11, and the two racks 13 are meshed with the gear 16. A torsion spring 15 for providing clamping force and for resetting is wound around the outer side of the fixed block 14, and the two ends of the torsion spring 15 are respectively connected to the gear 16 and the fixed block 14.
[0026] When it is necessary to dispense glue to the optical lens, the front clamping block 12 is pulled forward. When the clamping block 12 moves, it drives the sliding frame 11 to move forward in the front guide groove 10. The sliding frame 11 drives the lower rack 13 to move forward. When the rack 13 moves, it drives the gear 16 meshing on the inner side of the rack 13 to rotate clockwise. The torsion spring 15 is twisted and deformed by force and stores force. When the gear 16 rotates, it drives the rear rack 13 meshing with the gear 16 to move backward synchronously. The rear rack 13 drives the rear sliding frame 11 and the bracket 5 to move backward in the rear guide groove 10. The two clamping blocks 12 are pulled apart towards each other, and then the optical lens is placed on the bracket 5. Then the front clamping block 12 is released, and the torsion spring 15 releases the torsional stress and resets. Under the action, the gear 16 is forced to rotate counterclockwise, driving the racks 13 on both sides to move inwardly and oppositely, and the clamping blocks 12 on the front and rear racks 13 move inwardly and oppositely with the movement of the racks 13, clamping the optical lens placed on the support block 5. When dispensing glue, the torsion spring 15 and the clamping blocks 12 on both sides play a stabilizing and supporting role for the lens being dispensed glue, preventing the lens from being tilted and shifted by external forces, affecting the dispensing effect. When the dispensing work is completed, the front clamping block 12 is pulled forward. Under the action of the gear 16 and the rack 13, the torsion spring 15 is twisted by force, and the two clamping blocks 12 are pulled apart in opposite directions to take out the lens in the support block 5, and then the clamping block 12 is released. Under the action of the torsion spring 15 resetting, the clamping block 12, the rack 13 and other components move and reset.

The front and rear sides and the left and right sides of the upper top plate 2 are both connected with the adjusting screw 9 through threads, and the top of the adjusting screw 9 is in contact with the top of the lower bottom plate 1.
[0028] People can adjust the height and horizontal position of the upper plate 2 through the adjusting screw 9 on the upper plate 2, so that the sliding plate 4 and the supporting block 5 on the upper plate 2 are in a relatively flat and non-tilted state during the dispensing operation.
[0029] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
