Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the PCB board is welded using the hot-press welding method, since the welding accuracy required by the PCB board is very high, the alignment work at the beginning of the welding is particularly important. It will affect the subsequent welding accuracy and lead to defective products, so the staff usually takes a long time to place the PCB board, which will affect the processing efficiency

Embodiment 1

[0048] Embodiment 1: A kind of thermocompression welding system, such as figure 1 As shown, a thermocompression welding device 1 is included, and a feeding conveyor belt 11 is connected to the feed port of the thermocompression welding device 1 . Two infrared range-finding sensors 21 are fixedly connected to the position of the thermocompression welding equipment 1 close to the feeding conveyor belt 11. It is arranged along the conveying direction of the feeding conveyor belt 11. The distance between the two infrared ranging sensors 21 is equal to the width of the workpiece.

[0049] Such as figure 1 and figure 2As shown, the thermocompression welding equipment 1 includes an upper welding head 12 and a lower welding head 13 . An upper pressing plate 121 is fixedly connected to the upper welding head 12 , and a lower pressing plate 131 is fixedly connected to the lower welding head 13 . The upper platen 121 is fixedly connected with an upper high temperature resistant Tef...

Embodiment 2

[0052] Embodiment two: a kind of thermocompression welding method, concrete steps are as follows:

[0053] Step 1. Install two infrared distance measuring sensors 21 near the feeding conveyor belt 11 in the thermocompression welding equipment 1, so that the infrared light emitted by the two infrared distance measuring sensors 21 is parallel and the distance is equal to the width of the workpiece.

[0054] Step 2, the staff places the workpiece on the feeding conveyor belt 11, and makes two infrared rays pass along both sides of the workpiece as much as possible.

[0055] Step 3: If the position of the workpiece is incorrect, the two alarms 31 on the thermocompression welding equipment 1 will send out an alarm according to which side the workpiece is deflected to. Workers adjust the position of the workpiece. If the position of the workpiece is correct, the staff starts the feeding conveyor belt 11 and the thermocompression welding equipment 1 to weld the workpiece. It can ma...

Abstract

The invention discloses a bonding welding system and a welding method, which belong to the technical field of hot-press welding, and include hot-press welding equipment. Two infrared distance measuring sensors are fixedly connected to the position of the feeding conveyor belt. The distance between two infrared ranging sensors is equal to the width of the workpiece, and the thermocompression welding equipment is connected with a control system. The control system includes an infrared detection module and an alarm module. When the infrared rays emitted by the infrared ranging sensors are blocked, the infrared detection The module transmits electric signals, the infrared detection module sends the electric signals to the alarm module, and the alarm module sends out an alarm after receiving the electric signals.

Description

technical field [0001] The invention relates to the technical field of hot-press welding, in particular to a hot-press welding system and a welding method. Background technique [0002] At present, thermocompression welding is a welding process for connecting flexible circuit boards and rigid circuit boards. As an emerging manufacturing process and an important part in the field of microelectronic surface assembly technology, a stable and efficient thermocompression welding process is undoubtedly the guarantee of good product quality. important link. [0003] The prior art can refer to the Chinese invention patent whose application publication number is CN107755838A, which discloses a thermocompression welding device, including a working platform, a lifting device, a thermocompression welding head, and a welding head for sending tin wire to the thermocompression welding head. The position of the tin feeding device, the hot-press welding head is installed on the lifting end ...
