Description

TECHNICAL FIELD

[0001] The utility model relates to diode technical field, concretely is a kind of conversion fixture for high-efficiency diode of press-fit type automobile after welding. BACKGROUND

[0002] For the high-power press-fit type diode of vehicle, since the process of gluing and epoxy after the welding process of current high-efficiency diode needs to transfer the product in carbon mold to curing tray, and carbon mold and curing tray cannot accurately match and transfer product, a conversion fixture needs to be designed as intermediate medium to transfer a large number of diodes to curing tray.

[0003] Currently, curing tray of alumina material is generally used, so the material of current reversing disc is also alumina. However, since the design is too simple, three steps are needed to transfer diodes to curing tray, which greatly wastes time and reduces efficiency. Moreover, the phenomenon of semiconductor chip breakage caused by bumping during reversing occurs.

[0004] Therefore, a conversion fixture for high-efficiency diode of press-fit type automobile after welding is proposed. SUMMARY

[0005] The utility model aims at providing a conversion fixture for high-efficiency diode of press-fit type automobile after welding, which is simple in structure, convenient for employees to operate, can save a lot of time and labor, avoids bumping of single tube during transfer to other fixtures, chip breakage, and affects the performance and yield of products.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A conversion fixture for high-efficiency diode of press-fit type automobile after welding comprises lead wire baffle, positioning fixture and single tube bottom baffle arranged in sequence from top to bottom, and the positioning fixture is installed in carbon mold.

[0008] The lead wire baffle rotates and fixes single tube.

[0009] The positioning fixture is provided with matching hole for cooperation with curing tray, and the single tube bottom baffle is connected to curing tray.

[0010] Further, the positioning fixture is provided with connecting hole for cooperation with lead wire baffle.

[0011] Further, the positioning fixture is provided with connecting pin for cooperation with single tube bottom baffle.

[0012] Further, the single tube bottom baffle is provided with pin matching hole for cooperation with positioning fixture.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] Flexible, single flip, avoid product impact on the quality of the product;

[0015] Easy to operate, operators are more likely to quickly get started;

[0016] Solid and durable, simple structure design, save a lot of manpower and time. BRIEF DESCRIPTION OF DRAWINGS

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0022] Example 1:

[0023] Please refer to Figures 1-4 , the novel provides a technical scheme:

[0024] A conversion jig for welding of high-efficiency diode of press-fitting type automobile, comprising lead baffle 1, positioning jig 2, single tube bottom baffle 3 arranged in sequence from top to bottom, positioning jig 2 is installed in carbon mold, wire baffle 1 rotates and fixes single tube, jig 2 is provided with cooperation hole 2-1 for cooperation with curing tray, single tube bottom baffle 3 is connected to curing tray, jig 2 is provided with connecting hole 2-2 for cooperation with lead baffle 1, jig 2 is provided with connecting pin 2-3 for cooperation with single tube bottom baffle 3, and bottom baffle 3 is provided with pin cooperation hole 3-1 for cooperation with positioning jig 2.

[0025] Working principle:

[0026] First, rotate the lead baffle 1 to open, then the positioning jig 2 is installed in the carbon mold, and the press-fitting diode is matched into the groove, the jig is supported and the carbon mold is turned over, the diode is all fallen into the base positioning jig, then the lead baffle 1 is rotated back, and the single tube is fixed. Then the curing tray is matched with the cooperation hole 2-1, connected to the positioning jig 2 below, and the positioning baffle 3 is pulled away to the side, so that the single tubes can be arranged in the curing tray, and the positioning hole of the curing tray is matched with the tube base positioning design, so that the diodes are all transferred into the curing tray.

[0027] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
