Description

Technical Field

[0001] The present invention relates to a delivery device for microelectronic devices. Background Art

[0002] Microelectronic devices are small in size and large in number. If they need to be sorted and transported, a vibration plate is usually used. The vibration plate is an auxiliary device for automatic assembly machinery, which can sort out various products in an orderly manner. It can work with automatic assembly equipment to assemble various parts of the product into a complete product.

[0003] The vibration plate is powered by a vibration motor, which generates a directional frequency force when working. As long as you regard the vibration plate as a kind of inclined plane and then perform a physical force analysis on this inclined plane, you can easily understand its working principle.

[0004] When the electromagnetic coil of the vibration plate is working, the inclined surface will vibrate slightly up and down due to the electromagnetic attraction. The smooth operation can be achieved by adjusting the working frequency and gap of the vibration plate. The principle of vibrating electromagnet: the electromagnet is used to generate an alternating magnetic field. The vibrating part is an iron sheet suspended in front of the electromagnet. When the signal passes through the electromagnet, the magnetic field of the electromagnet changes, thereby causing the iron sheet to vibrate and make a sound.

[0005] The step nut vibrating plate of application number: 2012103456394 comprises a hopper, a bottom plate and a discharger, wherein the inner wall of the hopper is provided with a spiral ascending nut forward path, the outer wall of the hopper is provided with a spiral descending nut forward path, the end of the nut forward path is separated from the hopper to form a nut hanging seam, and a discharger is provided at the end of the nut hanging seam; the seam height of the nut hanging seam is between the diameters of the upper step and the lower step of the step nut; the width of the discharger is the height of the step nut; the present invention can only feed materials on demand, and cannot automatically discharge materials on demand. Summary of the invention

[0006] Purpose of the invention:

[0007] Provided is a vibrating plate metering feeding system capable of automatically adjusting loading and unloading (or feeding) and simultaneously metering an approximate quantity.

[0008] Technical solution:

[0009] The present invention provides a vibration plate metering feeding system, which has a feeding funnel, a conveying platform, and a vibration plate in descending order according to the feeding sequence. A photographing device is arranged above the vibration plate, and the photographing device is connected to the controller through a signal line, and the controller is connected to the vibration motor A of the vibration plate through a control line A. The controller has a visual recognition program, which can judge the approximate number of chips by taking pictures of the chips in the vibration plate. When the number of chips is less than the preset value range, the vibration motor B vibrates or increases the vibration frequency, so that the chips on the conveying platform are vibrated or accelerated to move forward and fall into the vibration plate. When the number of chips is greater than the preset value range, the vibration motor B stops vibrating or reduces the vibration frequency, so that the chips on the conveying platform are not vibrated or the vibration is reduced to reduce the number of chips falling into the vibration plate, and the number of chips in the vibration plate is maintained basically stable, so that the chips in the vibration plate are correctly arranged and sent to the subsequent workstations.

[0010] The conveying platform is preferably rectangular or trapezoidal in shape, and the front bottom side is preferably longer than the rear bottom side, so as to facilitate receiving and transferring multiple electronic components at the same time; the vibration plate is disc-shaped, so as to facilitate the chips to be arranged and conveyed one by one.

[0011] The controller is then connected to the vibration motor B of the vibration plate B (the conveyor is a vibration plate type conveyor, referred to as vibration plate B) through the control line B. When there are too many chips piled up in the vibration plate, it means that the chip back-end operation is blocked. Simply stopping the vibration of the vibration plate is not enough. The vibration of the vibration plate must be stopped, and the vibration motor B must be stopped or the frequency slowed down to eliminate the fault. When there are too few chips piled up in the vibration plate, it means that the chip back-end operation is smooth, and the chips must be continuously transported to the next process. The vibration of the vibration plate must be continued or accelerated, and the vibration motor B must continue to vibrate or increase the vibration frequency to ensure continuous and efficient production.

[0012] It is preferred that the vibration frequency of vibration motor A (continuous vibration to ensure high chip dispersion and facilitate photo identification) is higher than that of vibration motor B (intermittent vibration), and the amplitude of vibration motor A is smaller than that of vibration motor B. This ensures that the vibration plate continuously transports chips, one by one, while the conveyor table transports chips in an orderly manner, transporting one row at a time, and multiple chips fall into the vibration plate together.

[0013] Beneficial effects:

[0014] The vibrating plate metering feeding system of the present invention can vibrate the plate to arrange and disperse the vibrations evenly, which is convenient for taking photos and counting. At the same time, it controls the feeding funnel to discharge materials and controls the vibrating plate to convey components in sequence. It has many functions and high conveying efficiency. The two-stage vibration feeding mode can greatly reduce the amount of manual work. The two-stage vibration can be uniformly controlled by a controller. Both feeding and discharging can be accurately controlled, with a low failure rate. During the transmission process, there will be no phenomenon of component accumulation, extrusion, collision and dirt, and the quality of components is better guaranteed.
