Description

Technical Field

[0002] With the development of the IGBT industry and the increasing demand for automation, in order to solve the problem of automatic feeding of ultrasonic welding machines, an integrated welding needle automatic transportation device came into being. The integrated welding needle automatic transportation device is designed to transport the integrated welding needle to the ultrasonic welding machine welding head needle picking position through an automatic transportation system, so as to facilitate the welding machine to pick up the needle for welding. In this process, the welding needle needs to be inverted in the fixture from the initial disordered state through a flexible vibration plate, a needle picking mechanism, a transportation mechanism, etc., that is, the needle seat is facing down and the needle tip is facing up. However, the current integrated welding needle automatic transportation device is used to discharge the material at a certain frequency through a mechanical tooling. However, after the mechanical tooling picks up the material and discharges the material to the designated tooling, the time for the external material picking device to pick up the material will be wasted, which will delay the efficiency and continuity of the entire process.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0029] like Figure 1-Figure 5 As shown, in one embodiment, a flexible device for cross-feeding needles, a frame 1, the frame 1 is used as a bearing component of the entire device, and is used to place the following components, and a plurality of legs are arranged under the frame 1 (only some of the legs are shown in the figure) to maintain the stability of the frame 1;

[0030] The flexible vibration plate system 2 is fixed on the frame 1. The flexible vibration plate system 2 includes a flexible vibration plate body 201. A camera assembly 202 is arranged above the flexible vibration plate body 201. A light source may be arranged around the camera assembly 202 to provide additional lighting in poor light conditions. The flexible vibration plate body 201 contains a number of disordered welding needles, which are scattered in the vibration plate. The camera assembly 202 provides the position and angle of the welding needles for subsequent welding needle retrieval by photographing the positions of the welding needles.

[0031] The needle placement system 3 can move on the X-axis module 301. Specifically, the needle placement system 3 also includes a needle removal system, which includes an X-axis module 301, a Y-axis module 302, and a transplanting manipulator 303 (Z-axis module) arranged on the X-axis module 301. The transplanting manipulator 303 is provided with a rotating flip module 304, and the rotating flip module 304 is provided with a vacuum suction cup 305. The needle placement system 3 sucks the needle through vacuum according to the camera position, and makes the needle perpendicular to the tooling fixture through the first rotation, and then makes the needle inverted and perpendicular to the tooling fixture through the second rotation, and finally places the welding needle in the tooling fixture according to the specified shape through the movement of the XYZ axis. At this time, the cross needle supply system 4 can transport the fully loaded fixture to the welding needle waiting position.

[0032] Cross needle supply system 4, the cross needle supply system 4 includes a double-station tooling 401, the double-station tooling 401 operates alternately, and multiple welding needles are placed in each station fixture. When the external needle removal system takes needles from the double-station tooling 401, when taking needles from one fixture, the other station fixture can be placed synchronously, so as to maintain the continuity of needle removal, thereby improving the efficiency of needle removal and ensuring the continuity of the entire process.

[0033] Furthermore, a needle placement detection system is provided on one side of the cross needle supply system 4, and the needle placement detection system is used to detect whether the welding needle is placed in the double-station tooling 401. Specifically, a needle placement detection system is provided on the outside of the double-station tooling 401, wherein the double-station tooling 401 includes two groups of station fixtures arranged in parallel, and the upper surface of the station fixture is provided with a plurality of holes 404 along its length direction, and the holes 404 are used to place the welding needles, and a plurality of through micro-holes 404 are provided on both sides of the double-station tooling 401. 05, the position of the microhole 405 corresponds to the hole position 404. When one sensor in the needle placement detection system is working, and the sensor on the other side receives the signal emitted by the sensor on the opposite side, it means that there is no needle in the hole position 404. If the signal emitted by the sensor on the opposite side cannot be received, it means that there is a needle in the hole position 404. At this time, the driving motor drives the slider 402 to drive the double-station tooling 401 to move forward a short distance, so that the external needle removal system can pick up the welding needle of the next station, thereby maintaining the continuity of needle removal.

[0034] Furthermore, the transplanting robot 303 on the X-axis module 301 is specifically a PPU transplanting robot 303, and the rotating flipping module 304 connected at one end thereof is composed of at least two motors, which can drive the vacuum suction cup 305 at one end to rotate or flip so as to adjust the posture of the picked-up welding needle so that its needle seat stands upright with the needle seat facing downward and is placed in the tooling fixture.

[0035] Furthermore, for the double-station tooling 401, 15 soldering pins can be placed in each station fixture, that is, a total of 30 soldering pins can be placed, and the double-station tooling 401 alternately picks up and places soldering pins, which can shorten the waiting time and improve work efficiency.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
