[0002] The utility model relates to blank processing equipment, in particular to blank breaking equipment for lens barrel injection molding parts. Background technology:

[0004] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0005] At present, the demand in the optical industry is also increasing. For example, lens barrels and accessories of zoom lenses, etc., most of the lens barrels and zoom lens injection molded parts currently need to be reprocessed, such as removing excess risers and other scraps on the lens barrels and zoom lens injection molded parts; but many injection molded parts are currently removed manually, and manual processing has low efficiency and high labor intensity.

[0006] At present, a Chinese patent "An Ultrasonic Casting Separation Device and Method Thereof" with announcement number CN105665685B has been retrieved, which includes a frame and a casting placement table arranged on the frame, an ultrasonic casting separation device is arranged on the casting placement table, a casting conveying mechanism is arranged beside the casting placement table, and a material separation and dropping trough is arranged below the ultrasonic casting separation device. Although the present invention has a simple structure and can realize the separation of external waste materials and internal parts of the casting in the casting blank, and has high production efficiency; however, the equipment is only suitable for the processing of metal castings, and is not suitable for injection molded parts such as lens barrels and zoom lenses. Summary of the invention:

[0008] In view of this, the purpose of the utility model is to provide a lens barrel injection molded part breaking device, which has a reasonable design and is conducive to conveniently and quickly removing excess waste materials on the lens barrel injection molded parts.

[0032] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by ordinary technicians in the technical field to which the present application belongs.

[0033] The utility model lens barrel injection molding part breaking device comprises a frame 1 and a feeding mechanism 2, a material moving mechanism 3 and a breaking mechanism 4 arranged on the frame;

[0034] The feeding mechanism 2 may be a linear vibration feeder, which is an existing commercially available component.

[0035] The material breaking mechanism 4 includes a chuck 401 for clamping the lens barrel injection molded part and a telescopic clamping jaw 402 for breaking off the excess waste A2 of the lens barrel injection molded part A1 located on the chuck; the chuck 401 is a rotatable three-jaw chuck; the above-mentioned three-jaw chuck can be driven to rotate by a servo motor 403 arranged on the frame, and the use of the three-jaw chuck can form a space between the two jaws for the telescopic clamping jaw to extend into.

[0036] The telescopic clamping claw 402 is driven by the third finger cylinder 404 to realize the loosening and clamping actions, and the third finger cylinder 404 is driven to move by the telescopic cylinder 405 arranged on the frame, so as to realize the telescopic clamping claw approaching or moving away from the clamping disc.

[0037] The lens barrel injection molded part to be processed is installed in a chuck (three-jaw chuck), in which the waste part is located between two jaws. During operation, the chuck is driven by a servo motor and rotates 120 degrees each time so that the telescopic jaw can face the waste A2. The telescopic jaw 402 is initially in an open state, and then the third finger cylinder 404 and the telescopic jaw 402 are driven by the telescopic cylinder to move close to the lens barrel injection molded part to be processed. Then the third finger cylinder 404 drives the telescopic jaw 402 to clamp the waste A2, and then the telescopic cylinder drives the third finger cylinder 404 and the telescopic jaw 402 to retract. At this time, the waste is broken off from the lens barrel injection molded part to be processed. After the third finger cylinder 404 drives the telescopic jaw 402 to loosen, the waste falls into the waste bucket 5.

[0038] The material transfer mechanism 3 includes a first guide rail 301 vertically arranged with the linear vibrating feeder and a first slide seat 302 slidably arranged on the first guide rail. The first slide seat can be driven to slide by a first linear cylinder or a screw nut mechanism arranged on the frame.

[0039] The first slide seat is provided with a first clamping jaw 303 capable of clamping the lens barrel injection molded part to be processed on the output end of the feeding mechanism and a second clamping jaw 304 capable of clamping the processed lens barrel injection molded part in the chuck. The first clamping jaw 303 and the second clamping jaw 304 are arranged at an interval, and the distance between the two is equal to the distance between the linear vibration feeder and the chuck.

[0040] A waste bucket 5 is provided on the frame 1 below between the telescopic clamping claw and the chuck, and a finished barrel injection molded part bucket 6 is provided on the frame 1 beside the output end of the first guide rail.

[0041] The first clamping jaw 303 is driven by the first finger cylinder 305, and the second clamping jaw 304 is driven by the second finger cylinder 306. The first finger cylinder 305 and the second finger cylinder 306 are installed on a lifting seat 307, and the lifting seat 307 is driven to rise and fall by a lifting cylinder 308 installed on the frame; a guide rod 309 inserted into the first slide seat is vertically provided on the bottom surface of the lifting seat 307 to guide the vertical lifting of the lifting seat, and the lifting can be stable, accurate and reliable through the guide rod.

[0042] The lifting seat 307 is driven to rise and fall by the lifting cylinder 308, so that the first clamp can lift the lens barrel injection molded part to be processed at the discharge end of the linear vibration feeder after clamping it, and the second clamp can lift the lens barrel injection molded part after clamping it, so as to avoid interference between the first slide seat and the components thereon during horizontal movement.

[0043] The working principle of the new lens barrel injection molding breaking equipment is as follows:

[0044] The lens barrel injection molded part to be processed is transported from the feeding end to the output end by a linear vibration feeder, and is clamped by the first clamp at the output end. Then, the lens barrel injection molded part to be processed clamped by the first clamp is transported to the chuck by the first slide and clamped. Then, the waste material on the lens barrel injection molded part to be processed is clamped by the telescopic clamp after extension. Then, the waste material is broken off from the lens barrel injection molded part to be processed after the telescopic clamp is retracted. At the same time, the waste material falls after the telescopic clamp is relaxed (which can be received by a waste bucket); then, the second clamp clamps the processed lens barrel injection molded part in the chuck, and as the first slide moves, the second clamp moves to the output end of the first guide rail (at the same time, as mentioned above, the lens barrel injection molded part to be processed clamped by the first clamp is placed in the chuck), and at this time, the second clamp is released, and the processed lens barrel injection molded part falls (which can be received by a finished barrel of lens barrel injection molded parts).
