The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

As shown in FIG. 3, a colloid curing device 30 according to an embodiment of the present invention includes a curing illumination device 31, a carrier device 32, and a sensing control unit 33.

The curing illuminator 31 can be an ultraviolet light source for illuminating the workpiece 300. In this embodiment, the workpiece 300 may specifically be a lens and a spacer ring (not shown) loaded in a lens barrel (not labeled), and the contact surface of the lens and the spacer ring is coated with a gel.

The carrier 32 is used to carry the workpiece 300 and transport the workpiece 300. Specifically, the carrier 32 includes a conveyor belt 321 and a carrier 322 for carrying the workpiece 300. The carrying platform 322 is fixed on the conveyor belt 321 and is driven by the transmission belt 321 for linear motion. Of course, it can be understood that the workpiece 300 can also be directly disposed on the conveyor belt 321 and driven by the conveyor belt 321 for linear motion.

The sensing control unit 33 includes a first sensing unit 331a, a second sensing unit 331b, and a control unit 332. The first sensing unit 331a and the second sensing unit 331b are along the transmission direction of the carrier 32 (as shown in the figure). The directions indicated by the arrows in 3 are respectively disposed on both sides of the workpiece 300. Specifically, the first sensing unit 331a and the second sensing unit 331b are disposed on the transmission belt 321, and the distance from the first sensing unit 331a to the loading platform 322 is equal to the second sensing unit 331b. The first sensing unit 331a and the second sensing unit 331b are also in the transmission belt 321 when the transmission belt 321 drives the loading platform 322 and the workpiece 300 it carries in the direction indicated by the arrow in FIG. The workpiece 300 is moved in the direction indicated by the arrow in FIG. 3, that is, the workpiece 300 moves synchronously with the first sensing unit 331a and the second sensing unit 331b.

The first sensing unit 331a and the second sensing unit 331b can be configured as photodetecting devices, such as photodetectors, etc., which are electrically connected to the control unit 332 to sense respectively. The position of the workpiece 300 is output and a sensing signal indicative of the location of the workpiece 300 is output to the control unit 332.

The carrier 32 further includes a sliding member 323. The loading platform 322 defines a sliding rail 3220. The sliding member 323 cooperates with the sliding rail 3220 to slide the loading platform 322 on the sliding member. On 323. Therefore, the slider 323 has a guiding effect on the movement of the carrier 322, which can enhance the stability of the carrier 322 during movement. It can be understood by those skilled in the art that the cross section of the sliding member 323 can be polygonal (such as trapezoidal) or cylindrical. Correspondingly, the cross section of the sliding rail 3220 can also be polygonal (such as trapezoidal) or cylindrical.

Additionally, the carrier 32 may further include at least one rotating motor component (or rotating cylinder component) 324 to drive the conveyor belt 321 for linear motion. And the rotating motor element (or rotating cylinder element) 324 and the transmission belt 321 can be connected together by a gear structure. Preferably, the transmission belt 321 is provided with a protrusion 3210, and a recess 3222 corresponding to the protrusion 3210 is defined on the carrying platform 322.

Referring to Figure 4, in operation, the rotating belt element (or rotating cylinder element) 324 drives the belt 321 movement by means of a gear structure coupled thereto. It can be understood that, since the transmission belt 321 is provided with the protrusion 3210, and the groove 3222 is formed on the bearing platform 322, the protrusion 3210 can exert an abutting force on the side wall of the groove 3222 to slide the carrier 322 along the sliding member 323. At the same time, the workpiece 300 carried on the carrying platform 322 is moved along with the conveyor belt 321 (the direction of motion is as indicated by the arrow in FIG. 4). When the stage 322 is moved from I to II (the illumination range of the curing illuminating device 31), the coated coating on the workpiece 300 is irradiated by the curing illuminating device 31 to cure the coated coating on the workpiece 300. At this time, the first sensing unit The 331a is located at I, and the second sensing unit 331b is located at III, which are all outside the illumination range of the curing illumination device 31.

Referring to FIG. 5, the loading platform 322 and the workpiece 300 carried on the carrying platform 322 continue to move under the driving belt 321, and the first sensing unit 331a disposed on the conveyor belt 321 will also be synchronized with the workpiece 300. motion. When the first sensing unit 331a moves to II (within the illumination range of the curing illumination device 31), it will receive the illumination of the curing illumination device 31, and generate a current due to the photoelectric effect, and correspondingly output a sensing signal. The sensing signal is used to characterize the location of the workpiece 300. After the control unit 332 electrically connected to the first sensing unit 331a receives the sensing signal, the transmission belt 321 can be controlled to stop motion or reverse motion according to actual conditions. That is, the operator can determine the number of times the curing illumination device 31 is required to cure the colloid applied on the workpiece 300 according to actual needs, and the workpiece 300 can be cured only by receiving the curing illumination device 31 once. The control unit 332 can control the transmission belt 321 to stop moving; when the workpiece 300 needs to be cured by the curing illumination device 31 for multiple times, then the control unit 332 can control the transmission belt 321 to reverse (as indicated by the arrow in FIG. 5) )motion.

Further, as shown in FIG. 6, when the transmission belt 321 moves in the reverse direction and drives the second sensing unit 331b to move from III to II, the second sensing unit 331b can also receive the illumination of the curing illumination device 31 and correspondingly A sensing signal indicating the position of the workpiece 300 is output, and the control unit 332 can control the transmission belt 321 to stop moving or reverse movement according to the sensing signal.

Thus, the control belt 332 controls the reciprocating movement of the transport belt 321 so that the workpiece When the number of times the curing illumination device 31 is irradiated reaches the solidification of the coating applied on the workpiece 300, the control unit 332 controls the conveyor belt 321 to stop moving, thereby completing the process of curing the coated coating on the workpiece 300. Therefore, the operator can control the number of times the workpiece 300 receives the curing illumination device 31 according to actual needs to ensure that the coated colloid on the workpiece 300 is cured.

During the above motion, the loading table 322 and the workpiece 300 carried thereon have a stroke corresponding to the distance between the I and the III. Therefore, the colloid curing device 30 can control the stroke of the workpiece 300 to prevent the workpiece 300 from being colloidal. The conveyor belt 321 of the curing device 30 is dropped and damaged.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
