Description

Technical Field

[0001] This utility model relates to the field of diode technology, specifically to a fixture for positioning and arranging diodes. Background Technology

[0002] For high-power press-fit diodes used in automobiles, placement and positioning are required before testing. However, the placement and positioning of diodes is a difficult problem. Manual placement consumes a lot of manpower and time, and the positioning may not be accurate, which may affect the accuracy of test marking. Using a vibratory feeder for material feeding can easily cause poor product appearance and bent leads.

[0003] Currently, manual placement and positioning are used, with workers placing each piece one by one on aluminum alloy fixtures. This method is labor-intensive and inefficient, and cannot meet the requirements of large-scale production.

[0004] Another method uses a vibratory feeder, which arranges the diodes through vibration and then transports them to the testing machine via a track. However, the vibratory feeder can easily cause diode wear, resulting in poor product appearance. Excessive material in the vibratory feeder can also cause product compression, leading to bent leads and product scrap.

[0005] To address this, a fixture for positioning diodes is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a fixture for positioning diodes, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fixture for positioning diodes, comprising a base plate body, wherein multiple limiting strips are evenly installed on the base plate body, and positioning grooves are provided between the multiple limiting strips, and a cover plate body is installed on the top of the base plate body;

[0008] A feeding plate body is provided on one side of the base plate body, and multiple limiting plates are evenly installed on the feeding plate body, with the positions of the multiple limiting plates and multiple limiting strips being adapted to each other.

[0009] Preferably, a limiting protrusion is installed at one end of each of the plurality of limiting strips.

[0010] Preferably, base plate positioning plates are symmetrically installed on both sides of the base plate body.

[0011] Preferably, a cover plate positioning plate is installed on the inner side of the cover plate body, and the cover plate positioning plate is adapted to the bottom plate positioning plate.

[0012] Preferably, handles are installed on both sides of the main body of the feeding plate.

[0013] Preferably, the limiting plate is T-shaped.

[0014] Compared with existing technologies, the advantages of this utility model are: simple operation, high accuracy with fixture placement and positioning, ensuring accurate testing and coding, sturdy and durable, not easily damaged, reusable, saving costs, reducing labor costs, and significantly reducing manpower. Compared with manual placement and positioning, the operation is more efficient, accurate, and saves production costs. Compared with vibratory feeders, it better protects the product appearance and does not cause appearance defects. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a fixture for positioning diodes, including a base plate body 4, a plurality of limiting strips 1 are evenly installed on the base plate body 4, a positioning groove 3 is provided between the plurality of limiting strips 1, and a cover plate body 7 is installed on the top of the base plate body 4.

[0022] A feeding plate body 8 is provided on one side of the base plate body 4. Multiple limiting plates 10 are evenly installed on the feeding plate body 8, and the positions of the multiple limiting plates 10 are adapted to the multiple limiting strips 1.

[0023] like Figure 1 As shown: Each end of a plurality of limit strips 1 is equipped with a limit protrusion 5; through the above settings, the limit protrusion 5 can restrict the diode falling into the positioning groove 3, thus preventing it from falling from this side.

[0024] like Figure 1 and Figure 2As shown: Base plate positioning plates 2 are symmetrically installed on both sides of the base plate body 4, and cover plate positioning plates 6 are installed on the inner side of the cover plate body 7. The cover plate positioning plates 6 are adapted to the base plate positioning plates 2. Through the above settings, the base plate positioning plates 2 and the cover plate positioning plates 6 can cooperate with each other, so that the cover plate body 7 can be snapped onto the base plate body 4, thereby restricting and positioning the position of the cover plate body 7.

[0025] like Figure 3 As shown: Handles 9 are installed on both sides of the main body 8 of the feeding plate; with the above settings, the main body 8 of the feeding plate can be moved more conveniently and quickly.

[0026] like Figure 3 As shown: The limiting plate 10 is T-shaped; through the above settings, the T-shaped limiting plate 10 can restrict the position of the diode, such as... Figure 4 As shown, with the pin side facing upwards, the cylindrical portion is located between multiple T-shaped limiting plates 10, thereby restricting the position of the diode.

[0027] Working principle: First, cover plate 7 is placed on base plate 4, and the position of cover plate 7 is restricted by base plate positioning plate 2 and cover plate positioning plate 6. Then, the diode is poured into base plate 4, and base plate 4 is shaken to make the diode fall into the positioning groove 3. Due to the shape and weight of the diode, the side with the lead of the diode will face upward. Then, feed plate 8 is placed on one side of base plate 4. Then, cover plate 7 is removed, and the diode is pushed into the limiting plate 10 by one side of cover plate 7, thus completing the diode placement and positioning process.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
