Description

Technical Field

[0001] The utility model relates to the technical field of lens processing equipment, in particular to a glue dispensing device for lens processing. Background Art

[0002] Lens bonding is a very important process in lens assembly. It is to glue the lens into the lens barrel. The gluing equipment is generally a dispensing machine. When the dispensing machine is in use, the glue in the glue bottle is usually squeezed, and the squeezed glue is pressed out from the needle nozzle to dispense glue on the lens.

[0003] The existing dispensing machine can only dispense glue to one lens at a time, and requires a power device to drive the glue bottle up and down so that the needle nozzle is close to the dispensing position, and a power device to squeeze the glue in the glue bottle so that the glue is discharged from the needle nozzle to complete the dispensing operation. This dispensing operation not only requires more power equipment, but also can only dispense glue to one lens at a time, which limits the dispensing efficiency. For this reason, we designed a dispensing device for lens processing. Utility Model Content

[0024] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right" and so on to indicate directions or positional relationships, they only correspond to the drawings of the present application and are for the convenience of describing the present invention; it should be understood that if there are terms such as "end", "side", "end part", "lateral", "transverse", "longitudinal" and so on to indicate directions or positional relationships, they only correspond to the length and width of the corresponding parts, that is, "end part" indicates the head and tail area of the corresponding part in the length direction, and "side part" indicates the head and tail area of the corresponding part in the width direction; this is for the convenience of describing the present invention and does not indicate or imply that the device or element referred to must have a specific direction.

[0025] Example 1, combined with the attached Figure 1-5 A dispensing device for lens processing includes a device body 1 with a workbench 11, a dispensing assembly 2 is provided at a position corresponding to the position above the workbench 11 of the device body 1, and a glue storage barrel 3 is provided on the top of the device body 1 to provide glue for the dispensing assembly 2;

[0026] The dispensing assembly 2 includes a fixing frame 21 mounted on the device body 1. Both ends of the fixing frame 21 are slidably fitted with a rubber cylinder 22. A needle nozzle 23 is installed at the bottom of the rubber cylinder 22 through a one-way valve. A piston rod 24 matching the rubber cylinder 22 is provided in the inner cavity of the rubber cylinder 22, and the upper end of the piston rod 24 extends out of the rubber cylinder 22. The inner cavity of the rubber cylinder 22 is located below the piston rod 24 and is connected to the bottom of the inner cavity of the glue storage barrel 3 through a delivery pipe 25 and a one-way valve.

[0027] The dispensing assembly 2 further includes a driving structure capable of driving the rubber cylinder 22 and the piston rod 24 to move up and down, and the movement amplitude of the rubber cylinder 22 is smaller than the movement amplitude of the piston rod 24 .

[0028] In a possible example, the driving structure can be a telescopic device, the output end of which is correspondingly connected to the piston rod 24, and the output end of the telescopic device is correspondingly connected to the rubber cylinder 22 through a spring telescopic rod; specifically, the rubber cylinder 22 is provided with a limit member 211 at a position above the end of the corresponding fixing frame 21; that is, the telescopic shaft of the telescopic device descends, driving the rubber cylinder 22 and the piston rod 24 to descend, and when the limit member 211 contacts the fixing frame 21, the rubber cylinder 22 cannot continue to descend. At this time, the telescopic device can continue to drive the piston rod 24 to descend to squeeze the glue in the rubber cylinder 22, completing the dispensing operation; it should be noted that: when the rubber cylinder 22 cannot continue to descend, the appropriate distance between the needle nozzle 23 and the lens is reached.

[0029] In one possible example, Figure 2-5 The driving structure includes a swing rod 26 hinged to the middle of the fixing frame 21, and both ends of the swing rod 26 are provided with waist-shaped holes arranged along its length direction, and the waist-shaped holes are rotatably connected to the corresponding rubber cylinder 22; a support rod 27 is provided above the swing rod 26, and the outer end of the support rod 27 is provided with a waist-shaped hole rotatably connected to the upper end of the corresponding piston rod 24;

[0030] The drive structure also includes a drive device 28 for driving the swing arm 26 to swing back and forth. This drive device 28 can be a servo motor, as needed. That is, the drive device 28 can drive the swing arm 26 to flip up and down, causing one end of the swing arm 26 to rise and the other end to fall. The descending end of the swing arm 26 drives the corresponding rubber cylinder 22 downward, which in turn drives the needle nozzle 23 downward to the appropriate position. Simultaneously, the descending end of the corresponding support rod 27 drives the corresponding piston rod 24 downward. Because the piston rod 24 descends at a greater rate than the rubber cylinder 22, the piston rod 24 descends relative to the rubber cylinder 22, squeezing the glue within the rubber cylinder 22 and completing the dispensing operation. Similarly, the rising end of the swing rod 26 drives the corresponding glue cylinder 22 to rise, so that the needle nozzle 23 is away from the lens after glue dispensing. At this time, the next lens to be glued can be replaced. At the same time, the rising end of the corresponding support rod 27 drives the corresponding piston rod 24 to rise. Since the rising amplitude of the piston rod 24 is greater than the rising amplitude of the glue cylinder 22, that is, the piston rod 24 rises relative to the glue cylinder 22, and the glue in the glue storage barrel 3 is replenished into the glue cylinder 22.

[0031] As needed, a limiting member 211 is provided on the body of the rubber cylinder 22 above the end of the corresponding fixing frame 21 .

[0032] Furthermore, the glue storage barrel 3 and the piston rod 24 are rotatably connected to the corresponding waist-shaped holes through the pin shaft 29.

[0033] Furthermore, the pin shaft 29 is located at a position corresponding to the waist-shaped hole cavity and is rotatably sleeved with a wear-resistant sleeve 210; as needed, the positions of the two ends of the pin shaft 29 corresponding to the wear-resistant sleeve 210 can be used to limit the axis of the wear-resistant sleeve 210 through a retaining spring.

[0034] As required, the end of the swing rod 26 has a U-shaped structure located outside the rubber cylinder 22, and both side walls of the U-shaped structure are provided with waist-shaped holes that are rotatably connected to the rubber cylinder 22.

[0035] It should be noted that the lower end of the piston rod 24 has a piston plate that matches the inner cavity of the rubber cylinder 22.

[0036] Preferably, the glue storage barrel 3 and the glue cylinder 22 are made of transparent materials.

[0037] On the whole, the glue dispensing device can replenish glue in time after each glue dispensing, and the glue storage barrel 3 is located above the glue cylinder 22, which can effectively prevent air from entering the glue cylinder 22 and affecting the glue dispensing quality.

[0038] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
