Abstract
Description
Technical Field
[0001] The present invention relates to the field of plastic product production, specifically to the blanking of plastic products. Background Art
[0002] The rear cover plate of a display is formed in an injection molding device, and the formed rear cover plate is in a vertical state. After mold opening, a suction cup at the end of the manipulator adsorbs the rear cover plate. Among them, a frame structure is provided at the end of the manipulator. The frame structure is hinged to the manipulator, and a cylinder is connected between the manipulator and the frame structure. The suction cups are distributed along the edge of the frame structure. After mold opening, the suction cups on the frame structure adsorb the rear cover plate of the display. At this time, the frame structure is also in a vertical state.
[0003] A conveyor belt is provided beside the injection molding device, and the end of the conveyor belt is the manual position. After the suction cup at the end of the manipulator adsorbs the rear cover plate of the display, it moves to above the conveyor belt and then descends. When approaching the conveyor belt, the cylinder drives the frame structure to rotate 90 degrees, and the frame structure and the adsorbed rear cover plate change to a horizontal state. Then, the suction cup releases the rear cover plate, and the rear cover plate falls on the conveyor belt. The rear cover plate moves to the manual position, and the worker packs the rear cover plate with a packaging bag.
[0004] In the above process, after the manipulator takes the rear cover plate from the injection molding device, it rises and then translates, crosses the fence of the injection molding device, and then descends to above the conveyor belt. The frame structure then rotates 90 degrees to become horizontal. After releasing the rear cover plate, it resets and takes the next rear cover plate from the injection molding device. Thus, the manipulator requires a long operation time and operation path during the blanking process, which is not conducive to improving production efficiency. Summary of the Invention
[0005] The technical problem to be solved by the present invention: The manipulator配套 with the injection molding device requires a long operation time and operation path during the blanking process, which is not conducive to improving production efficiency.
[0006] To solve the above technical problem, the present invention provides the following technical solution: A worm-type blanking channel for a plastic cover plate, including a corrugated pipe. The corrugated pipe is vertically arranged, the top end of the corrugated pipe is fixed on a bracket, the bottom end of the corrugated pipe is connected to a vibration mechanism, and the bottom end of the corrugated pipe is located above the conveyor belt. The maximum size of the rear cover plate of the display is the distance between a pair of diagonals. When the corrugated pipe is stretched by the vibration mechanism, the minimum inner diameter of the inner cavity of the corrugated pipe is greater than the maximum size of the rear cover plate of the display; when the corrugated pipe contracts, the minimum inner diameter of the inner cavity of the corrugated pipe is less than the maximum size of the rear 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 its internal toothed structure increases; that is, the minimum inner diameter of the bellows cavity increases, exceeding the maximum size of the product. The product inside the bellows cavity will fall under the influence of gravity. When the bellows is compressed, the inner diameter of its internal toothed structure decreases; that is, the minimum inner diameter of the bellows cavity decreases, falling below the maximum size of the product. The toothed structure inside the bellows prevents the product from falling. The regular stretching and compression of the bellows causes the product inside to gradually fall along the bellows, eventually landing on the conveyor belt.
[0008] The robotic arm that retrieves the injection-molded product from the injection molding equipment simply places the product into the corrugated tube. There is no need for it to descend above the conveyor belt. The corrugated tube can wriggle the product downwards like a worm, allowing it to land stably on the conveyor belt.
[0009] The top of the bracket is equipped with a top fixing ring, which is fitted into the recess at 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 upright of the support. The vertical sleeve is connected to the cam mechanism, and the cam mechanism is installed on the upright of the support.
[0011] The cam mechanism includes a motor connected to the upright, a crank-connecting rod mechanism connected to the motor shaft, and a transverse connecting rod on the vertical sleeve. The connecting rod of the crank-connecting 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 up and down along the upright, causing the bottom connecting frame to vibrate at a fixed frequency and amplitude.
[0012] The motor is mounted on a triangular bracket, and an upper clamp and a lower clamp are provided on one side of the triangular bracket. The upper clamp and the lower clamp are clamped on the upright of the bracket.
[0013] A pair of uprights of the support are mounted on the frame of the conveyor belt.
[0014] The corrugated pipe of this invention allows the product (the back cover of the display) from the robotic arm to wriggle downwards like a worm, ensuring the product lands stably on the conveyor belt. This eliminates the need for the robotic arm to descend above the conveyor belt to release the product. Thus, this invention is not only cost-effective but also improves production efficiency.

[0027] Combination Figure 1 , Figure 3 The worm-like feeding channel of the plastic cover includes a corrugated tube 10, which is set vertically. The top end of the corrugated tube is fixed on the bracket 20, and the bottom end of the corrugated tube is connected to the vibration mechanism 30. The bottom end of the corrugated tube is located above the conveyor belt 40. The maximum size of the back cover of the display is the distance between a pair of diagonals. When the corrugated tube is stretched by the vibration mechanism, the minimum inner diameter of the corrugated tube cavity is greater than the maximum size of the back cover of the display. When the corrugated tube is contracted, the minimum inner diameter of the corrugated tube cavity is less than the maximum size of the back cover of the display.
[0028] The top of the bracket 20 is provided with a top fixing ring 21, which is fitted into the recess at the top of the corrugated pipe 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 sleeved on the upright 22 of the support. The vertical sleeve is connected to the cam mechanism, and the cam mechanism is installed on the upright of the support.
[0030] The cam mechanism 31 includes a motor 311 connected to the upright 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, and 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. An upper clamp 36 and a lower clamp 37 are provided on one side of the triangular bracket, and the upper clamp and the lower clamp are clamped on the upright 22 of the bracket.
[0032] A pair of uprights 22 of the support 20 are mounted on the frame 41 of the conveyor belt 40.
[0033] Motor 311 drives crank 313 of the crank-connecting rod mechanism, which in turn drives connecting rod 312. The connecting rod drives vertical sleeve 33 to reciprocate up and down along vertical rod 22, causing bottom fixed ring 32 to vibrate up and down at a fixed frequency and amplitude. Driven by bottom fixed ring 32, bellows 10 regularly stretches and contracts. When bellows 10 stretches, the inner diameter of its internal toothed structure increases, meaning the minimum inner diameter of the bellows cavity increases, exceeding the maximum size of the product. The product inside the bellows cavity falls under gravity. When bellows 10 contracts, the inner diameter of its internal toothed structure decreases, meaning the minimum inner diameter of the bellows cavity decreases, falling below the maximum size of the product. The toothed structure inside the bellows prevents the product from falling. The regular stretching and contraction of bellows 10 causes the product inside to gradually fall along the bellows, eventually landing on conveyor belt 40.
[0034] A robotic arm that retrieves the injection-molded product from the injection molding equipment places the product into a corrugated tube 10. The corrugated tube can move the product downwards like a worm, allowing the product to fall stably onto the conveyor belt 40.
[0035] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
