Description

Technical Field

[0001] The present invention relates to the technical field of resistance welding machines, and more specifically to a plug-in laser solder ball device and a welding method thereof. Background Art

[0002] Before welding the HDMI terminals, pre-tinning is required. The traditional method uses a single pad laser solder ball tinning method. The principle is that only one solder ball can be accommodated in the nozzle each time. While the laser melts the solder ball, an inert gas is used to spray the solder ball onto the pad. The disadvantage of this method is that only one solder ball can be sprayed each time, and the efficiency is relatively low. For example, the pads of the HDMI terminals are distributed on two terminal surfaces, one side is 9 pins, and the other side is 10 pins. This device requires at least 19 + 1 actions to complete the tinning of all pads, that is, 19 times of tinning and 1 time of turning over. Not only is the process cumbersome, wasting a lot of time, energy and manpower, but also it is easy to produce welding defects and quality problems. Moreover, once a mistake occurs during the whole process, the entire 19 + 1 actions will be invalid, and the error tolerance rate is very low. Summary of the Invention

The position of the positioning latch corresponds to that of the positioning bushing 525, and the positioning pin can be inserted into the blind hole to achieve the positioning effect; the pull-out cylinder works, pulls the positioning pin to compress the spring, and leaves space for the tooling disk 521 to rotate. When the tooling 52 plate rotates to a position parallel to the turntable 51, the pull-out cylinder does not work, and the positioning pin moves toward the positioning bushing 525 under the action of the spring, and is inserted into the blind hole to accurately position the tooling disk 521. At this time, the tooling disk 521 is completely parallel to the turntable 51 and is in a completely horizontal state.

[0094] A positioning circular bushing and a positioning diamond bushing are provided on the tooling 52 for mutual positioning with the bearing plate 233.

[0095] When the turntable 51 needs to rotate, the flipping cylinder contracts to separate the flipping gear from the tooling gear 524. When the turntable 51 rotates to the predetermined station, the flipping cylinder extends to drive the flipping slide to move upward until the flipping gear meshes with the tooling gear 524, and then the flipping motor works to drive the tooling 52 to flip 180 degrees; at this time, the detection disk 523 is located inside the optoelectronic detection probe, and it is confirmed whether the tooling 52 is in the horizontal position by detecting whether the detection slit is vertical.

[0168] The turntable 51 rotates 60 degrees to transfer the tooling 52 from the unloading station to the feeding station;

[0169] From this point on a separate workflow is completed;

[0170] Focus on the whole:

[0171] In actual work, some steps can be performed simultaneously to save time and improve efficiency;

[0172] As attached Figure 18 Step 1 is a continuous process that does not stop, that is, the circular vibration plate 11 and the linear vibration plate 12 work continuously to transfer the connector to the positioning plate 122. If there is a connector in the positioning plate 122, the other connectors are arranged in sequence in the vibration plate body 121 and wait;

[0189] If shutdown is required, reverse the above processes and gradually stop Step 2, Step 4, Step 6, Step 8, Step 10, and Step 12 until all steps are stopped, then the shutdown is completed.

[0190] In other embodiments, a repair welding device can be added at the unloading section 4. The structure of the repair welding device is basically the same as that of the laser welding section 2, with the difference being that each time, one solder ball is unloaded, carried, and welded, so as to perform individual repair welding on the positions with missing welds. The repair welding device further includes a flipping device 55 to flip the tooling 52, so as to perform repair welding on the positions with missing welds on both the front and back sides.
