Description

Hot-pressing welding mechanism

Technical Field

The utility model relates to a hot-pressing welding mechanism.

Background

Hotbar soldering is a common name for pulse heating reflow soldering, and simply, the process is to heat two parts which are previously coated with soldering flux and plated with tin to a temperature sufficient for melting the solder (lead-free solder melting point: 217 ℃), and after cooling and solidification, the two parts form a permanent electrical mechanical connection through the solidified solder. In the process, a certain pulse voltage is loaded on the hot pressing head, the high-impedance hot pressing head is heated by using low-voltage large current, the temperature of an object in contact with the high-impedance hot pressing head is increased, and the two objects in contact with the high-impedance hot pressing head are welded together after the temperature is increased to the melting point of soldering tin. The technology is generally applied to the connection of electronic devices. However, when in use, the cutter head is required to be completely parallel to the object to be pressed when the cutter head is lowered to the object to be pressed, so that the object to be pressed is uniformly heated. At present, the general method is that a screw of a cutter head locked on a hot press is loosened, then the cutter head is adjusted to a manual mode, when the cutter head is lowered and an object to be pressed is pressed, the screw is locked after the cutter head is completely contacted, and finally the cutter head is lifted. This means that need be directed against different batch products or the manual debugging level of tool, because product or tool difference, and the welding tool bit is only one, and the welding tool bit is suitable for all products and tools, and under the narrow and small circumstances in space in addition, it is very troublesome to debug.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the shortcoming that exists among the prior art, provide a but simple structure is reasonable, welding tool bit automatically regulated be on a parallel with wait to press the hot-pressing welding mechanism on thing surface.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

a hot-press welding mechanism comprises a bracket, a welding module, a parallel mechanism and a tool bit, wherein the welding module, the parallel mechanism and the tool bit are arranged from top to bottom; the parallel mechanism further comprises limiting parts arranged on two opposite sides of the supporting plate, the limiting parts penetrate through the bottom surface of the supporting plate, the bottom ends of the limiting parts extend out of the bottom surface of the supporting plate, and the distance between the bottom ends of the limiting parts and the top surface of the tool bit is adjustable, so that the rotating range of the tool bit can be controlled.

Further, the bracket is also connected with a driving mechanism which can drive the bracket to vertically move; the welding module is connected with the bracket.

Furthermore, the limiting piece is a screw; the supporting plate is provided with a through hole, the screw penetrates through the through hole, and the external thread of the screw is matched with the internal thread of the inner wall of the through hole.

Further, the cutter head comprises a cutter head body and a fixing piece for mounting the cutter head body; the fixing piece is connected with the rotating shaft, and a gap exists between the upper surface of the fixing piece and the bottom surface of the supporting plate.

Further, the parallel mechanism is symmetrical left and right.

The technical scheme of the utility model, broken through the fixed mode of tool bit and welding module lug connection in the past, part welding module and tool bit, intermediate junction automatic correction parallel mechanism, through the rotation of pivot, autogiration adjustment is parallel as for the product surface when the tool bit body descends to the product surface, need not to carry out manual debugging to different batch products or tool, do not receive the influence of product batch or tool difference, reduced the anastomotic debugging degree of difficulty of welding tool bit and product, even change different batch products also not influenced. And the size of the automatic adaptation amount of the tool bit can be adjusted by adjusting the extension length of the limit screw on the bottom surface of the supporting plate, and the whole mechanism is simple in structure and has a good economic effect.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Reference is made to the accompanying drawings. The utility model discloses a support 2 and from last welding module 3, parallel mechanism 4 and the tool bit 5 that sets up extremely down, support 2 is a loading board in this embodiment, the welding module 3 is fixed to one of them side of loading board, and the another side is connected and can be driven the vertical actuating mechanism who upwards moves or move down of loading board. The parallel mechanism 4 comprises a support plate 40 horizontally fixed at the bottom of the welding module 3 and a rotating shaft 41 horizontally fixed at the center of the bottom of the support plate 40, and the cutter head 5 comprises a cutter head body 50 and a fixing member 51 for mounting the cutter head body. The fixing member 51 is hung on the rotation shaft 41 at a distance from the support plate 40 so that the cutter head body 50 can rotate about the rotation shaft 41 in a vertical plane, like a seesaw. The parallel mechanism 4 further includes a limiting member 42 disposed on two opposite sides of the supporting plate 40, specifically, the limiting member is a screw, the screw penetrates through the supporting plate 40, and the bottom end of the screw extends out of the bottom surface of the supporting plate, and the external thread of the screw is matched with the internal thread of the through hole for mounting the screw on the supporting plate, so that the distance between the bottom end of the screw and the fixing member 51 can be adjusted by rotating the screw, thereby controlling the rotating range of the tool bit body 50.

The driving mechanism can comprise a servo motor and a vertical screw rod driven by the servo motor, and the other surface of the bearing plate and a nut in threaded connection with the screw rod are fixedly connected with the bearing plate.

In particular, the parallel mechanism 4 in this embodiment has a bilaterally symmetric structure.

In this embodiment, the welding module is a general thermocompression welding module currently available on the market.

During the use, because the tool bit is fixed on the automatic correction module, the in-process that moves down, at the in-process with being pressed the thing contact, according to the difference on pressed thing or tool both sides, the tool bit body passes through pivot self-adaptation and rotates, guarantees to contact completely with the product and coincide, adjusts the adjusting screw on both sides to control the size of automatic adaptation volume, convenient to use.
