Description
Technical Field
[0001] This utility model relates to a device for automatically loading electronic components into a fixture. Background Technology
[0002] Electronic components, especially those with terminal electrodes, often need to be vertically mounted in the positioning slots of test or aging fixtures with the electrodes at the top and bottom to facilitate performance testing, power-on aging, and other operations.
[0003] Due to the small size and wide variety of electronic components, manual loading into fixtures is inefficient and costly, necessitating the development of technologies to replace manual operations. For specialized electronic components, it is crucial to avoid damaging the component surface during handling, ensure compatibility with different component sizes, and ideally, require compatibility between test fixtures and aging fixtures. While existing technologies have achieved compatibility between test fixtures and aging fixtures in some component areas, they cannot achieve the non-damaging, flexible, and automated vertical loading of components of various sizes into test or aging fixtures.
[0004] Existing technology uses a perforated screen, specifically designed for elongated shapes with electrodes on the narrower end faces. The perforation size is made slightly larger than the narrower cross-sectional dimensions of the component, and the perforation distribution aligns with the positioning slots in the fixture. The fixture is placed under the screen, close to it, ensuring the perforations correspond to each positioning slot. After the component is placed in the screen, shaking the connection between the screen and the fixture, or scraping the capacitor across the screen, causes the component to enter the positioning slots vertically. This method saves labor costs but has significant limitations. Friction between components is noticeable during operation, potentially damaging the component's appearance and failing to meet high aesthetic requirements. Furthermore, screen replacement is necessary for components of different sizes, hindering applications requiring convenient and simple operation. Finally, it is unsuitable for components with electrodes on the larger end faces rather than the smaller ones.
[0005] To address the above problems, this utility model proposes the following solution. Utility Model Content
[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a device for automatically loading electronic components into a fixture, which prevents friction between components and meets the requirements for high appearance; in addition, it is convenient and simple to operate for components of different sizes, and can also be easily operated for components whose electrodes are not on the smaller end face but on the larger end face.
[0007] To achieve the above objectives, the technical solution of this utility model is to design an automatic electronic component loading fixture, comprising a flexible vibratory plate, a movable suction head, a guide rail that can rotate the component from horizontal to vertical, and a fixture. The component outlet of the guide rail is set at the positioning groove of the fixture, and the movable suction head is set on the flexible vibratory plate.
[0008] A further technical solution is that the guide rail is a curved track and the outer side of the guide rail is provided with a blocking surface to ensure that the component does not detach from the guide rail during the guiding process. The component inlet of the guide rail is set horizontally, and the component outlet of the guide rail is set vertically.
[0009] A further technical solution is that the guide rail is provided with multiple guide grooves of the same specification, and the positioning groove in the fixture matches the guide groove.
[0010] A further technical solution is that the guide rail is provided with several guide rails of the same specification arranged in an array, and the fixture is provided with the same number of positioning slots arranged in an array, and the positioning slots in the fixture match the guide rails.
[0011] A further technical solution is that the fixture is provided with multiple rows of positioning slots, and the number of guide rails is one row or the same as the number of positioning slots, and the guide rails match one row of positioning slots on the fixture.
[0012] A further technical solution is that the guide rail is a guide groove plate, which is composed of multiple guide rail arrays, and the guide rail arrays are matched with the sizes of different components.
[0013] The present invention also provides a method for automatically loading electronic components into a fixture, comprising the following sequential operation steps: using a suction head to pick up a capacitor horizontally from a flexible vibrating plate, correcting the component's orientation and position, moving the capacitor to the guide rail entrance and placing it down, the component sliding along the guide rail, gradually changing from an inclined to a steep incline, and finally falling vertically into the positioning slot of the fixture.
[0014] A further technical solution is that the guide rail and the fixture move relative to each other, loading the components into the positioning slots in the fixture row by row, or the guide rails with the same number of rows are matched with the positioning slots with the same number of rows, and the operation of loading the components into the fixture is completed when the two remain relatively stationary.
[0015] A further technical solution involves selecting a fixture of a specific size for components, placing a guide slot plate above the fixture, and using a guide slot array that matches the component size. A row of positioning slots in the fixture is positioned at the component outlet of the corresponding guide slot array. A suction head array places the component of the corresponding size at the component inlet of the selected guide slot array. The component passes through this guide slot array and falls from the component outlet into a row of positioning slots in the fixture. A guide rail array moves relative to the fixture, loading the component into each positioning slot array in the fixture row by row. Here, "specific size component" refers to a component of a non-standard size.
[0016] The advantages and beneficial effects of this utility model are: no friction occurs between components, which can meet the requirements of high appearance; in addition, it is convenient and simple to operate for components of different sizes, and it is also convenient to operate for components whose electrodes are not on the smaller end face but on the larger end face.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0022] like Figures 1 to 3 As shown, this utility model is a device for automatically loading electronic components into a fixture, comprising a flexible vibratory plate 1, a movable suction head 2, and a guide rail 3 that can rotate the component from horizontal to vertical. The component outlet of the guide rail corresponds to the positioning groove 4 of the fixture. The suction head picks up the capacitor horizontally from the flexible vibratory plate, corrects the component's orientation and position, moves the capacitor to the entrance of the guide rail and places it down. The component slides along the guide rail, gradually changing from an inclined to a steep incline, and finally falls vertically into the positioning groove of the fixture.
[0023] The guide rail has a certain inclination at its entrance, and then gradually turns to vertical during the guiding process. The outer side of the guide rail is provided with a blocking surface 5, so that the component will not detach from the guide rail during the guiding process.
[0024] The guide rail can be provided with multiple guide grooves of the same specification, corresponding to multiple positioning grooves of the same size in the fixture, which can improve the efficiency of loading components into the fixture.
[0025] The guide rail can be provided with multiple guide rails of the same specification arranged in an array, corresponding to multiple positioning slots of the same size arranged in an array in the fixture. The fixture can be provided with multiple rows of positioning slots. The guide rail can move relative to the fixture to load the component into the positioning slot in the fixture row by row. Alternatively, multiple rows of guide rails can be used to correspond to multiple rows of positioning slots, and the operation of loading the component into the fixture can be completed when the two are kept relatively stationary.
[0026] The guide rails, composed of multiple guide rail arrays accommodating different component sizes, are referred to as guide slot plates. For components of a specific size, a fixture of the corresponding size is selected, the guide slot plate is placed above the fixture, and the corresponding size guide slot array is used. A row of positioning slots in the fixture aligns with the exit of the corresponding size guide slot array. The suction head array places the component of the corresponding size at the entrance of the selected guide slot array. The component passes through this guide slot array and falls from its exit into a row of positioning slots in the fixture. The guide rail array moves relative to the fixture, loading the component into each positioning slot array in the fixture row by row.
[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
