Automatic frame pressing device, automatic frame centering and pressing device and automatic frame centering and pressing system

Abstract

The invention provides an automatic frame pressing device, an automatic frame centering and pressing device and an automatic frame centering and pressing system. The automatic frame pressing mechanism comprises a table supported by a bracket, and a plurality of ball screws driven by a servo motor, and the table is provided with a plurality of positioning cylinders, a Y-axis sliding plate, and X-axis right and left sliding plates with pressing cylinders and the positioning cylinders, and can also be provided with Z-axis cylinders at four corners. The automatic frame centering and pressing device also comprises a jacking translation device and an automatic centering device. The automatic frame centering and pressing system also comprises a truss with mechanical paws, and a production line body based on the automatic frame centering and pressing device. In the invention, the product quality is improved, and the influence of manual knocking on production is reduced; the fragment problem caused by knocking is solved, and manpower and fragment loss in the production process as well as labor intensity and man-hour loss are reduced, and the slash seam problem fed back on the market is solved; and uniform splicing gap of four edges of the product is ensured, and the customer satisfaction and the overall image of the brand are improved.

Description

technical field [0001] This application relates to an automatic frame pressing device and its automatic centering pressing device and system, which are used for accurate installation of product shells and belong to the technical field of product manufacturing machinery Background technique [0002] At present, various products with shells need to use the process steps of shell assembly when they are manufactured, and this requirement is typical for home appliances. With the continuous development of science and technology and the continuous improvement of living standards, the application of various large-scale equipment with shells in various fields is increasing, and various equipment is generally developing in the direction of thinner and thinner. Taking TV as an example, the size of a flat-panel TV The thickness of the high-end flagship product is within 5mm, the thickness of the middle-end star product is controlled within 5-10mm, and the thickness of the low-end and hi...

Problems solved by technology

With the continuous development of science and technology and the continuous improvement of living standards, the application of various large-scale equipment with shells in various fields is increasing, and various equipment is generally developing in the direction of thinner and thinner. Taking TV as an example, the size of a flat-panel TV The thickness of the high-end flagship product is within 5mm, the thickness of the middle-end star product is controlled within 5-10mm, and the thickness of the low-end and high-volume product is controlled within 40mm; At present, the shell is mainly installed manually, and the screw is used to lock it after snapping together. Because the surface frame is a spliced ​​structure, there will be gaps and flashing seams at the four corners (such as Figure 12 ), manual knocking on the flash seam of the front shell with a percussion rod not only uses valuable human resources, but also makes it difficult to control the quality of the snap-fitting by manual operation, which leads to misalignment before the snap-fitting, resulting in panel interference and fragments from time to time. In addition, the installation process requires personnel to knock on the product surface frame. Fragments appear due to irregular manual knocking, and the flash seam can only be guaranteed to be within 0.2mm, which cannot meet market demand.

On the other hand, manual preloading can only be used for products with light weight and small size, but it is difficult to use manual preloading for products with large size and heavy weight. It can be seen that manual operation not only has large errors, low efficiency, and wastes human resources. , and it is difficult to guarantee the product quality, especially the fragments caused by the above two reasons, resulting in losses
