Description

Swing device for transferring electronic components

technical field

The invention belongs to the field of electronic components, in particular to a swinging device for transferring electronic components.

Background technique

For the convenience of use and transportation, to meet the needs of the assembly of modern electronic equipment automation production lines, and to improve the assembly efficiency of electronic components, it is generally required to be taped. For example, the automatic tape machine is applied to the automatic tape packaging of two-pole electronic components such as diodes. When the device enters the feeder, it needs to rotate and reciprocate in one direction through the suction heads that are evenly distributed on the outer edge of the swing plate. The device is picked up, and then the device is picked up to the braid and placed in place through the relay method, and the function of other types of plate placement is basically the same. The disadvantage of this method is: the swing plate absorbs the device repeatedly in one direction, not only the error accumulates more and more, the accuracy of the device is getting worse and worse, but also seriously affects the working speed of the whole machine, the work efficiency is low, and the reliability is poor. .

Contents of the invention

The purpose of the utility model is to provide a swinging device for transferring electronic devices with simple structure, reliable operation and doubled working efficiency.

The utility model solves its technical problem and realizes by taking the following technical solutions:

The swinging device for transferring electronic devices is composed of a swinging plate body, a vacuum air pipe, a suction head, a swinging plate body, and an air chamber. A wobble plate body is fixed axially on the body, and a linear cylinder is fixed axially on the base plate at the lower part of the wobble plate body. Two independent and symmetrical air chambers are formed on the wobble plate body. There are two groups of suction heads installed in uniform and symmetrical indexing, and the two groups of suction heads are respectively connected to two air chambers through vacuum air pipes.

Moreover, among the two groups of suction heads evenly distributed on the wobble plate, the two adjacent suction heads on the other side are the main suction heads, and the two adjacent suction heads on the other side are the main discharge suction heads. The angle is the angle between two adjacent suction heads.

Advantage and positive effect of the present utility model are:

Two independent air chambers are used and the air chambers are respectively connected to two sets of suction heads, which can simultaneously pick up or put down components in the left and right rotation directions; moreover, the swing angle of the wobble plate is only two adjacent suction heads The angle between the heads improves the accuracy of picking up the device and doubles the work efficiency. The overall structure of the utility model is relatively simple, the work efficiency is high, there is no accumulated error, and the accuracy of grasping devices is good.

Detailed ways

Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:

In this swing device for transferring electronic devices, the lower part of the swing plate body 2 is fixed on the pneumatic swing table 12 through the base plate 11 in the axial direction (because the connection mode of each part of the device is basically bolt and screw connection, and the connection mode is relatively Simple, the screws and bolts in this embodiment have no labels, and will not be repeated), and the pneumatic swing table is generally installed on a workbench (not shown in the figure). A wobble plate body 7 is fixed axially on the wobble plate body, and the wobble plate body and the wobble plate body are positioned by positioning pins 6 . A linear cylinder 9 is fixed on the base plate axially at the lower part of the wobble plate body, and the top of the linear cylinder is mounted on the wobble plate body. The pneumatic oscillating table realizes the left and right plane swing of the wobble plate, and the linear cylinder realizes the up and down displacement of the wobble plate body and the wobble plate body, both of which are commercially available products. Two independent air chambers 8 are formed symmetrically on the wobble plate body. These two air chambers are generally arc-shaped and sealed by the pressure plate 5 . These two air chambers are connected to the vacuum source through the intake pipe 10 . Two groups of suction heads are arranged symmetrically and uniformly distributed on the surface of the wobble plate, and the number of each group of suction heads is determined according to actual requirements. In this embodiment, there are 8 suction heads in each group and a total of 16 suction heads. The two groups of suction heads communicate with the two air chambers through the vacuum tube 4 respectively. Among the two groups of suction heads evenly distributed on the swing plate, the two adjacent suction heads divided into the main suction suction head (as shown in the number 1 and the number 3 in Figure 1), and the two adjacent suction heads on the other side are For the main suction head (there is no label in the figure), the swinging angle of the wobble plate is the angle between two adjacent suction heads, such as the angle between suction head 1 and suction head 3.

The working principle of the utility model is:

Plate feeding is the main feeding method for electronic components. Pneumatic swing table and linear cylinder drive the swing plate to complete the process of moving the device as follows:

Left suction head action: drop suction, lift, left swing, drop release, lift, right swing return; right suction head action: drop suction, lift, right swing, drop release, lift , Left swing back; the action is carried out according to the program, and the vacuum suction and vacuum breaking of the air chamber are also set according to the program. When working, the wobble plate is driven by the pneumatic oscillating table to swing to the left (to the right), and then the linear cylinder descends to absorb materials, rises and then swings back, and descends to discharge materials. When one main suction head finishes taking and discharging the material, the other main suction head also swings over to take the material. The left suction head group completes the counterclockwise transfer of devices between each station, and the right suction head group completes the clockwise transfer. Since device transfer can be performed in both directions, transfer efficiency is doubled.
