Description

A high-stability double-sided loading arch bridge SMT placement machine

technical field

The invention relates to the field of mounting electronic components, in particular to an arch-bridge type SM mounter with high stability and double-sided feeding.

Background technique

With the rapid development of the electronic manufacturing industry, the processing industry of mounting electronic components on circuit boards has been increasingly adopted by electronic and electrical manufacturers. The placement machine is usually composed of an XY precision positioning platform and a placement head with placement function. However, the common placement head assembly is installed on the cantilever. When the placement head assembly is translated to the edge of the cantilever through program control, due to the force, it will cause the placement head assembly to shake and become unstable on the cantilever. The steps of picking, positioning and mounting of the chip head component will cause adverse effects, thereby affecting the quality of the product.

Chinese patent "CN202713802U" is a cantilever type high-efficiency placement machine, which uses cantilever positioning to improve the operating space of the placement machine, but due to the existence of the cantilever, it does not solve the problem of material suction and positioning when the placement head assembly is on the edge , placement instability, placement accuracy is not high, therefore, in urgent need of a placement machine with high stability.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a high-stability arch-bridge type SMT placement machine capable of bilateral feeding.

The technical solution of the present invention is: a high-stability double-sided feeding arch bridge type SMT placement machine, including a frame and a placement head assembly, the top of the frame is provided with an XY mobile platform that drives the placement head assembly. The XY mobile platform includes two X-direction rails arranged side by side, an arch that straddles the two X-direction rails and slides with the X-direction rails, and a beam fixedly installed on the arch. The Y-direction track extending in the direction, and the patch head assembly is slidably matched with the Y-direction track. , can replace the patch head assembly with different functions according to the needs, and use the structure of the double arch to support the beam to ensure that the product to be processed can be stably absorbed even if the patch head assembly moves to the edge position, and the placement area is set in the middle to ensure The processing process is stable, and through the above design, it solves the problem that the beam and the placement head need to perform Y movement at the same time, resulting in too heavy weight and slow moving speed, and improves the placement efficiency.

Both sides of the XY mobile platform are provided with feeding units.

The feeding unit includes a board feeding mechanism and a feeding mechanism.

The beneficial effects of the present invention are:

1. By setting the double arch structure to support the beam, the placement head assembly moves along the Y axis through the Y axis, and the double arch can move along the X axis direction, so as to meet the needs of the placement head assembly to absorb the products to be processed at different positions At the same time, it ensures the stability of the process of picking up the product to be processed even if the placement head moves to the most edge position.

2. Set the placement area at the center of the frame to ensure the stability of the placement process;

3. Through the structural design of the double arch support beam, the PCB board can be loaded on both sides at the same time, which improves the work efficiency.

4. The patch head assembly can be detachably installed on the Y axis, and the patch head assembly with different functions can be replaced according to the needs.

5. Compared with the original cantilever structure, the structure supported by double arches has a lower processing cost of the machine.
