Description

Technical Field

[0001] The invention relates to the technical field of automatic feeding, in particular to a DBC ceramic substrate post-processing horizontal line automatic feeding device. Background Art

[0002] Directly bonded copper ceramic substrate, also known as DBC ceramic substrate, is an advanced circuit substrate technology. By directly bonding copper foil to ceramic substrate, efficient heat dissipation and reliable electrical connection can be achieved. DBC ceramic substrate is widely used in power electronics, electric vehicles, solar inverters and LED lighting. The excellent thermal management ability and electrical performance of DBC ceramic substrate make it play an important role in high-power, high-density and high-reliability applications. After the copper-clad ceramic substrate is sintered, the pattern on the surface of the copper foil will be transferred. Before the transfer, it needs to go through the post-processing horizontal line to clean the surface of the substrate. The existing technology has defects: when loading, the ceramic substrate needs to be taken out from the material frame manually and placed on the horizontal conveying roller. It is required to separate the substrates one by one manually, which has a large labor intensity and increases the labor cost. When placing the ceramic substrate on the horizontal line manually, the substrates need to be arranged one by one. The substrates must be released only after they touch the roller to avoid ceramic cracks. This greatly tests the patience of the staff, and the possible risk of ceramic cracks cannot be controlled, and the quality of the product cannot be guaranteed. When loading, the substrates need to be placed with the front side facing up and in the same direction, which reduces production efficiency. Summary of the invention

After the clamp 805 rotates the ceramic substrate 180°, the first motor 708 is controlled to rotate, and the suction device 711 moves to the center of the ceramic substrate. The vacuum pump 7115 is controlled to start to adsorb the ceramic substrate, and the first motor 708 is controlled to reverse to take the ceramic substrate out of the clamp 805.

[0038] After the front and back of the ceramic substrate are adjusted, the suction device 711 rotates the ceramic substrate to be parallel to the horizontal line, rotates the ceramic substrate 90°, so that the short side of the ceramic substrate faces the horizontal line, and when the ceramic substrate is reversed 180°, the ceramic substrate is reversed 90°. Finally, the conveying device 7 places the ceramic substrate with the front and back and direction unified on the horizontal line.

[0039] When all the ceramic substrates in the material frame in the transfer device 6 are placed in the horizontal line, the control system controls the cylinder rod of the lifting cylinder 608 to be retracted, and the cylinder rod drives the lifting plate 601 to descend to the unloading device 9, controls the gear shaft of the second rotating cylinder 605 to rotate, and the gear shaft drives the second clamping block to rotate to the release position, controls the transfer conveyor belt 602 to start, and transports the material frame to the unloading conveyor belt 901, and the control system controls the cylinder rod of the lifting cylinder 608 to extend, and the cylinder rod drives the lifting plate 601 to rise to the loading conveyor belt 501, and the unloading conveyor belt 901 transports the material frame to the blocking block 902. When the second pressure sensor senses pressure, the control system controls the unloading conveyor belt 901 to stop. When the material frame is manually taken away, the second pressure sensor can no longer sense pressure, and the control system controls the unloading conveyor belt 901 to start.

[0040] Although the embodiments of the present invention have been shown and described, it is to be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, substitute and vary the above embodiments within the scope of the present invention without departing from the principles and purpose of the present invention.
