Description of the invention: [Technical field to which the invention pertains] A method of dispensing a mold is particularly concerned with a dispensing method that enhances the grip of the lens and the uniformity of dispensing. [Prior Art] The lens module of the eyepiece or optical instrument usually includes a lens holder, a mirror, a lens group, a spacer ring and a filter, and a light sheet, wherein the lens group and the filter are along the optical axis direction < $ # &#& ' m : Mountain = together. The outer wall of the lens barrel and the inner wall of the lens holder are provided with screws, and the mirror is screwed into the lens holder.

Shot, as shown in Figure 2, that is, the dispensing device has a fixed amount of glue per unit time. Therefore, when the lens module starts to rotate, the amount of glue on the coating is relatively stable after the rotation is stable. Therefore, the glue of the guide point is uneven, which affects the quality of the glue and even affects the quality of the lens module. There is a clock to provide a record of St. Brewer, 4·. A kind of dispensing method to achieve uniform lens module 200812707 Dispensing is necessary. [Summary of the Invention] * The following describes an example to improve Dispensing method for dispensing uniformity of a lens module. A dispensing method comprising the steps of: providing a dispensing lens group and a dispensing device; and rotating the to-be-dispensed lens module relative to the dispensing device In the stage of the dispensing of the lens to be dispensed from the start to the rotation, the first dispensing pressure control dispensing device performs dispensing; after the dispensing lens is stabilized, the second dispensing is utilized. The pressure control dispensing device performs dispensing, and the first dispensing pressure is less than the second dispensing pressure; when the dispensing lens group rotates one turn, the second dispensing pressure control dispensing device is stopped to make the dispensing The device stops dispensing. Compared with the prior art, the dispensing method uses a first dispensing pressure control dispensing device to dispense with the dispensing lens to be dispensed from the start-up rotation to the rotation stabilization stage. The slow rotation speed of the lens module when starting the rotation is performed after the rotation of the dispensing lens module is stabilized, and then the dispensing force is controlled by a second dispensing pressure control device to match the glue lens module to be stabilized. Cyclone Speed. Since the rotation speed of the lens module in the rotation phase is relatively stable, the rotation speed of the rotation phase is changed from small to large, so that the first glue pressure is corrected on the basis of the second glue pressure, so that the first one is The glue pressure is less than the second glue discharge pressure, so that the glue output amount of the dispensing device matches the rotation speed of the glue lens module to be dispensed, thereby achieving uniform dispensing. [Embodiment] Hereinafter, an adjustable lens mold will be described by way of examples. The dispensing method of the dispensing uniformity 7 200812707. The dispensing method of the first embodiment comprises the following steps: ~ The first step is to provide a dispensing lens module 10. Referring to Figure 3, the dispensing lens module 10 includes a lens barrel 110, a lens group 120, and a spacer ring 130. The lens group 120 and the spacer ring 130 are sequentially fixed in the lens barrel 110 in the optical axis direction. The outer wall of the lens barrel 110 may be provided with a thread, the thread and the lens holder ( The threaded plate fits inside the figure and can be screwed into the lens holder for fixing. The dispensing device 30 includes a cartridge 31, a needle 32, and a pressing device 33. The cartridge 31 is for holding glue. The needle 32 is in communication with the cartridge 31 for dispensing. The pressing device 33 is connected to the cartridge 31 for applying pressure to the glue in the cartridge 31 so that the glue can be ejected from the needle 32. The pressure applying means 33 applies pressure to the glue in the cartridge 31 to be adjusted as needed. The pressure applying device 33 is connected to a monitoring device 40, which in turn is connected to the rotating platform 20 for monitoring the change in the rotational speed of the dispensing lens module 10. The monitoring device 40 can transmit the change of the rotational speed of the to-be-dispensed lens module 10 to the pressing device 33, and the pressing device 33 can adjust and control the glue according to the speed change of the rotation of the lens module 10 to be dispensed. pressure. The pressure applying device 33 can be connected to a pressure regulating valve, other pressure control system, or equipped with a computer program control to adjust the amount of pressure applied to the glue in the cartridge 31. In the second step, the to-be-dispensed lens module 10 is rotated relative to the dispensing device 30, and the dispensing device 30 is used to dispense the dispensing lens module 10. The to-be-dispensed lens module 10 is fixed to the rotating platform 20. When dispensing, the needle 32 of the dispensing device 30 is first placed at the intersection of the spacer ring 130 and the inner wall of the mirror 8 200812707, so that the to-be-dispensed lens module 1 is rotated relative to the dispensing device 30 while being pressurized. The device 33 applies a glue pressure to the glue in the cartridge 31 for dispensing. In this embodiment, the lens module is rotated by rotating the platform 2〇. The to-be-dispensed lens module 1〇 is fixed to the rotating platform 2〇. The rotating platform 2 is rotatable about its central axis of rotation. The central axis of the to-be-polished lens module ίο is in line with the central axis of rotation 21 of the rotating platform 20, so that the rotating platform 2 〇 rotates the to-be-dispensed lens module to achieve dispensing. φ Referring to Fig. 4, first, in the stage in which the lens module 1 is rotated to the rotation stabilization stage, the pressing device 33 applies a first dispensing pressure 42 to the glue in the cartridge 31. The first dispensing pressure 42 has a stable pressure value a, and the glue in the cartridge 31 is injected by the needle 32 under the action of the first dispensing pressure 42 and is applied to the lens to be dispensed by the I* Ai speed rotation. The spacer ring of group 10 is on top of it. Next, when the dispensing lens module 10 is rotated stably, a second dispensing pressure 44 is applied to the glue in the cartridge 31. In the case where the diameter of the lens barrel 11 is 9 mm, the time required for one rotation is usually about 5 seconds, and it is usually about 0.5 second after the start rotation to stabilize the rotation. The second dispensing pressure 44 also has a stable pressure value b. Since the speed at which the dispensing lens module 10 starts to rotate is slow, the amount of glue required to be emitted from the needle 32 per unit time should be relatively small, and the unit time ejected from the needle 32 can be adjusted by adjusting the dispensing pressure. The amount of glue. Therefore, the pressure value a of the first glue pressure 42 applied to the glue water in the rubber cylinder 31 is smaller than the pressure value b of the second glue pressure 44, and the first glue pressure 42 is smaller, so that the glue is emitted from the needle 32. The amount of water is also reduced accordingly, and it will not cause a large amount of glue to accumulate when the head mirror of the 200812707 head mirror ίο rotates slowly. In addition, the speed after the stable rotation of the dispensing lens module 10 is greater than the speed at which the first rotation is started, and the second dispensing pressure 44 is larger, which ensures that the amount of glue injected from the needle 32 is correspondingly increased. The glue is evenly applied to the spacer ring 130. In the third step, when the dispensing lens module 10 is rotated one turn, the second dispensing pressure 44 is stopped to control the dispensing device 30, so that the dispensing device 30 stops dispensing. When the dispensing lens module 10 is rotated one turn, the second dispensing pressure 44 is stopped to control the dispensing device 30 and the lens module 10 to rotate; or the second dispensing pressure 44 can be stopped to control the dispensing device 30. So that the dispensing device 30 stops the glue injection first, and then stops the rotation of the lens module 10. Since the lens module 10 is ejected from the deceleration to the stop rotation phase, since no glue is ejected from the needle 32 of the dispensing device 30, no glue is repeatedly applied to the spacer ring 130, thereby ensuring uniformity of dispensing. The dispensing method of the second embodiment is substantially the same as the dispensing method of the first embodiment. During the dispensing process, the rotating platform 20 drives the dispensing lens module 10 to rotate, and at the same time, a first dispensing pressure 52 and a second dispensing pressure 54 are applied to the glue in the cartridge 31 by the pressing device 33 for dispensing. Referring to FIG. 5, the dispensing method of the second embodiment is different from the dispensing method of the first embodiment in that the first dispensing pressure 52 is a small to large gradient pressure having a minimum pressure value c and a The maximum pressure value d, when the dispensing lens module 10 is started to rotate, the pressing device 33 applies the first dispensing pressure 52 to the glue in the cartridge 31. At this time, the pressure of the first dispensing pressure 52 is the smallest. The pressure value c, then the pressure value of the first dispensing pressure 52 is gradually changed from the minimum pressure value c to 200812707 to the maximum pressure value d, so the amount of glue injected from the needle 32 will also change from small to large. Since the glue lens module 1 is rotated from the start to the steady state, the speed is also changed from small to large, so that the glue ejected from the 'needle 32' can be uniformly applied to the spacer ring 13〇. For example, if the lens module 10 rotates from the start to the steady rotation phase, the relationship curve of the speed (v)_time (1) satisfies the quadratic equation V2=mt, (m> 〇), and the first dispensing pressure 52 at this time. The relationship curve of (F)-time (1) can also be matched to satisfy the quadratic enthalpy (PC) 2 = nt, (n > 0). Thus, in the lens module 1 〇 from the start rotation to the stable rotation phase, the first glue pressure 52 matches the rotation speed of the lens module 1 ,, and the first glue pressure 52 pressure value matches the glue lens module to be dispensed. The change of the rotational speed of the dispensing device 30 changes, that is, the change trend of the first dispensing pressure 52(p) with time (1) and the speed (v) of the lens module 1 (corresponding to the change trend of the cymbal, the needle can be obtained from the needle 32, the glue is evenly applied to the spacer ring 130. Thereafter, the rotation speed of the to-be-dispensed lens pull group 1 Q enters the stable step, and the pressure-sensing device 33 can apply the second glue pressure to the glue in the cartridge 31. Since the lens module 1〇 rotates at a stable speed, the second rubber pressure material also has a stable pressure value d to ensure a stable amount of glue to achieve uniform coating of the glue on the spacer ring 130. The dispensing lens module 1 is slower when starting to rotate, and the amount of glue required to be emitted from the needle 32 per unit time should be relatively small, and the unit time ejected from the needle 32 can be adjusted by adjusting the dispensing pressure. The amount of glue. Therefore, apply The pressure value of the first glue pressure 52 on the glue water in the rubber cylinder 31 is smaller than the pressure value d of the second glue pressure 54, so that the knees and water in the injection of the needles 32 from 200812707 are also reduced accordingly. When the plastic lens module 1 Q rotates slowly, it will not cause a large amount of glue to accumulate. Since the pressure value of the first pressure value 52 gradually changes from the minimum pressure value c to the maximum pressure value, it is necessary to ensure the first out The pressure value of the glue pressure 52 is less than the pressure value d of the second glue discharge pressure 54. The maximum pressure value of the first glue discharge pressure 52 should be consistent with the pressure value of the second glue discharge pressure 54. The dispensing method of the embodiment The uniformity of the dispensing glue 10 can be further improved. The advantage of the above dispensing device is that during the dispensing process, the first to be dispensed from the start-up rotation to the rotation stabilization stage of the dispensing mirror® head module The glue pressure control dispensing device performs dispensing to match the rotation speed of the to-be-dispensed lens module when the rotation is started, and after the rotation of the dispensing lens module is stabilized, the second dispensing pressure control dispensing device is utilized. Dispensing to match The rotation speed of the dispensing lens module after stabilization. Since the rotation speed of the lens module is relatively stable, the rotation speed of the rotation phase is gradually changed from small to large, so the pressure of the first dispensing pressure is based on the second dispensing pressure. The above-mentioned / Xin correction, so that the first dispensing pressure is less than the second dispensing pressure, so that the dispensing amount of the dispensing device matches the rotation speed of the dispensing lens module, thereby achieving uniform dispensing.
