Worm type blanking channel of plastic cover plate

Abstract

The worm type discharging channel of the plastic cover plate comprises a corrugated pipe, the corrugated pipe is vertically arranged, the top end of the corrugated pipe is fixed to a support, the bottom end of the corrugated pipe is connected with a vibration mechanism, and the bottom end of the corrugated pipe is located above a conveying belt. The vibration mechanism regularly stretches and compresses the corrugated pipe. When the corrugated pipe is stretched, the inner diameter of the tooth-shaped structure inside the corrugated pipe is increased, and a product in the inner cavity of the corrugated pipe can fall under the action of gravity. When the corrugated pipe is compressed, the inner diameter of the tooth-shaped structure in the corrugated pipe is reduced, and the tooth-shaped structure in the corrugated pipe prevents a product from falling down. The corrugated pipe is regularly stretched and compressed, so that products in the corrugated pipe gradually fall down along the corrugated pipe and finally stably fall on the conveying belt. In this way, the mechanical arm does not need to descend to the position above the conveying belt to release products, and the production efficiency can be improved.

Description

Technical Field

[0001] The invention relates to the field of plastic product production, and in particular to blanking of plastic products. Background Art

[0002] The rear cover of the display is formed in the injection molding equipment, and the rear cover is in an upright state after being formed. After the mold is opened, the suction cup at the end of the robot arm absorbs the rear cover. Among them, the end of the robot arm is provided with a frame structure, the frame structure is hinged with the robot arm, and a cylinder is connected between the robot arm and the frame structure. The suction cups are distributed along the edge of the frame structure. After the mold is opened, the suction cups on the frame structure absorb the rear cover of the display, and at this time, the frame structure is also in an upright state.

[0003] There is a conveyor belt next to the injection molding equipment, and the end of the conveyor belt is the manual position. After the suction cup at the end of the robot sucks the rear cover of the display, it moves to the top of the conveyor belt and then descends. When it approaches the conveyor belt, the cylinder drives the frame structure to rotate 90 degrees, and the frame structure and the sucked rear cover are transformed into a horizontal state. After that, the suction cup releases the rear cover, and the rear cover falls on the conveyor belt. The rear cover moves to the manual position, and the worker packs the rear cover with a packaging bag.

[0004] In the above process, after the robot takes the rear cover from the injection molding equipment, it rises and then moves horizontally, crosses the fence of the injection molding equipment, and then descends to the top of the conveyor belt. The frame structure then rotates 90 degrees to become horizontal. After releasing the rear cover, it resets and takes the next rear cover from the injection molding equipment. In this way, the robot needs a longer running time and running path during the unloading process, which is not conducive to improving production efficiency. Summary of the invention

[0005] The technical problem solved by the present invention is that the robot arm matched with the injection molding equipment requires a long running time and running path during the material unloading process, which is not conducive to improving the production efficiency.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a worm-type feeding channel for a plastic cover plate, comprising a bellows, the bellows is arranged vertically, the top end of the bellows is fixed on a bracket, the bottom end of the bellows is connected to a vibration mechanism, and the bottom end of the bellows is located above a conveyor belt; the maximum size of the back cover plate of the display is the distance between a pair of diagonals, and when the bellows is stretched by the vibration mechanism, the minimum inner diameter of the inner cavity of the bellows is greater than the maximum size of the back cover plate of the display; when the bellows contracts, the minimum inner diameter of the inner cavity of the bellows is smaller than the maximum size of the back cover plate of the display.

[0007] The vibration mechanism vibrates at a fixed frequency and amplitude, regularly stretching and compressing the bellows. When the bellows is stretched, the inner diameter of the toothed structure inside it becomes larger, that is, the minimum inner diameter of the inner cavity of the bellows becomes larger and larger than the maximum size of the product, and the product in the inner cavity of the bellows will fall under the action of gravity. When the bellows is compressed, the inner diameter of the toothed structure inside the bellows becomes smaller, that is, the minimum inner diameter of the inner cavity of the bellows becomes smaller and smaller than the maximum size of the product, and the toothed structure inside the bellows prevents the product from falling. The bellows is regularly stretched and compressed, causing the product inside to gradually fall along the bellows and finally fall on the conveyor belt.

[0008] The robot that gets the injection molded product from the injection molding equipment can put the product into the bellows without descending to the top of the conveyor belt. The bellows can move the product downward like a worm, allowing the product to fall stably on the conveyor belt.

[0009] The top of the bracket is provided with a top fixing ring, and the top fixing ring is sleeved in the inner recess of the top of the corrugated pipe.

[0010] The vibration mechanism includes a bottom connecting frame and a cam mechanism. The bottom connecting frame includes a bottom fixing ring and a vertical sleeve fixedly connected to the bottom fixing ring. The vertical sleeve is movably sleeved on the vertical pole of the bracket. The vertical sleeve is connected to the cam mechanism, and the cam mechanism is installed on the vertical pole of the bracket.

[0011] The cam mechanism includes a motor connected to the vertical rod, a crank connecting rod mechanism connected to the motor shaft, and a vertical sleeve is provided with a transverse connecting rod. The connecting rod of the crank connecting rod mechanism is connected to the transverse connecting rod. The motor drives the crank of the crank connecting rod mechanism, the crank drives the connecting rod, and the connecting rod drives the vertical sleeve to reciprocate and rise and fall along the vertical rod, so that the bottom connecting frame vibrates at a fixed frequency and amplitude.

[0012] The motor is installed on a triangular bracket. An upper clamp and a lower clamp are arranged on one side of the triangular bracket. The upper clamp and the lower clamp are clamped on a vertical pole of the bracket.

[0013] A pair of uprights of the bracket are mounted on the frame of the conveyor belt.

[0014] The bellows of the present invention can move the product (the rear cover of the display) from the manipulator downward like a worm, so that the product falls stably on the conveyor belt, and the manipulator does not need to descend to the top of the conveyor belt to release the product. In this way, the present invention is not only low-cost, but also conducive to improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A top fixing ring 21 is provided at the top of the bracket 20 , and the top fixing ring is sleeved in the recess at the top of the corrugated tube 10 .

[0029] like Figure 3 The vibration mechanism 30 includes a bottom connecting frame and a cam mechanism 31. The bottom connecting frame includes a bottom fixing ring 32 and a vertical sleeve 33 fixedly connected to the bottom fixing ring. The vertical sleeve is movably mounted on the vertical rod 22 of the bracket. The vertical sleeve is connected to the cam mechanism, and the cam mechanism is installed on the vertical rod of the bracket.

[0030] The cam mechanism 31 includes a motor 311 connected to the vertical rod 22 and a crank connecting rod mechanism connected to the motor shaft. The vertical sleeve 33 is provided with a transverse connecting rod 34. The connecting rod 312 of the crank connecting mechanism is connected to the transverse connecting rod.

[0031] The motor 311 is mounted on a triangular bracket 35 , and an upper clamp 36 and a lower clamp 37 are provided on one side of the triangular bracket. The upper clamp and the lower clamp are clamped on the vertical rod 22 of the bracket.

[0032] A pair of upright poles 22 of the bracket 20 is installed on a frame 41 of the conveyor belt 40 .

[0033] The motor 311 drives the crank 313 of the crank-connecting rod mechanism, the crank drives the connecting rod 312, and the connecting rod drives the vertical sleeve 33 to reciprocate and rise and fall along the vertical rod 22, so that the bottom fixing ring 32 vibrates up and down at a fixed frequency and amplitude. Driven by the bottom fixing ring 32, the bellows 10 stretches and contracts regularly. When the bellows 10 stretches, the inner diameter of the toothed structure inside it becomes larger, that is, the minimum inner diameter of the inner cavity of the bellows becomes larger and larger than the maximum size of the product, and the product in the inner cavity of the bellows will fall under the action of gravity. When the bellows 10 contracts, the inner diameter of the toothed structure inside the bellows becomes smaller, that is, the minimum inner diameter of the inner cavity of the bellows becomes smaller and smaller than the maximum size of the product, and the toothed structure inside the bellows prevents the product from falling. The bellows 10 stretches and contracts regularly, so that the product inside it gradually falls along the bellows and finally falls on the conveyor belt 40.

[0034] The robot that obtains the injection molded product from the injection molding equipment puts the product into the bellows 10 , which can move the product downward like a worm, so that the product falls stably on the conveyor belt 40 .
