Description

Technical Field

[0001] The invention relates to a device and a method for automatically loading electronic components into a fixture. Background Art

[0002] Electronic components, especially those with terminal electrodes, often need to be installed in a positioning slot in a test or aging fixture in a vertical manner with the electrodes at the top and bottom to facilitate performance testing, power-on aging and other operations.

[0003] Since electronic components are small in size and of many types, manual loading into fixtures is inefficient and costly, and it is necessary to develop technologies that can replace manual operations. For special electronic components, it is necessary not to damage the surface of the components during operation, and it is also necessary to facilitate compatibility operations for different component sizes, and the test fixture and the aging fixture must be compatible as much as possible. The existing technology has achieved compatibility between test fixtures and aging fixtures in some component fields, but it is impossible to achieve non-destructive and flexible operations that automatically load components of various sizes into test or aging fixtures in a vertical manner.

[0004] The prior art uses a screen with leak holes. For the long strip shape and the electrodes at the two thinner end faces, the size of the leak holes is made slightly larger than the thinner cross-sectional size of the component, and the distribution of the leak holes is consistent with the distribution of the positioning grooves in the fixture. The fixture is placed under the screen, close to the screen, so that the screen holes correspond to each positioning groove. When the component is placed in the screen, shake the combination of the screen and the fixture, or scrape the capacitor across the screen, and the component will enter the positioning groove of the fixture in a vertical manner. This method can save labor costs, but it has great limitations. The friction between the components is more obvious during operation, which will cause certain damage to the appearance of the components and cannot meet the needs of high requirements for appearance; in addition, for components of different sizes, the screen needs to be replaced, which cannot meet the application requirements for convenient and simple operation; finally, it is not suitable for components whose electrodes are not on the smaller end face but on the larger end face.

[0005] To solve the above problems, the present invention proposes the following solutions. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects existing in the prior art and provide a device for automatically loading electronic components into a fixture, in which no friction occurs between the components and the demand for high requirements on appearance is met; in addition, the operation is convenient and simple for components of different sizes, and components whose electrodes are not on the smaller end face but on the larger end face can also be easily operated.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is to design a device for automatically loading electronic components into a fixture, which includes a flexible vibration plate, a movable suction head, a guide rail and a fixture that can turn the components from horizontal to vertical. The component outlet of the guide rail is arranged at the positioning groove of the fixture, and the movable suction head is arranged on the flexible vibration plate.

[0008] A further technical solution is that the guide rail is a curved rail and a blocking surface is provided on the outer side of the guide rail to ensure that the component does not leave the guide rail during the guiding process, the component inlet of the guide rail is arranged horizontally, and the component outlet of the guide rail is arranged vertically.

[0009] A further technical solution is that the guide rail is provided with a plurality of guide grooves of the same specification, and the positioning grooves in the fixture match the guide grooves.

[0010] A further technical solution is that the guide rail is provided with a plurality of guide rails of the same specification arranged in an array, the fixture is provided with the same number of positioning grooves arranged in an array, and the positioning grooves in the fixture match the guide rails.

[0011] A further technical solution is that a plurality of rows of positioning grooves are provided on the fixture, the number of guide rails is one row or is the same as the number of positioning grooves, and the guide rails match a row of positioning grooves on the fixture.

[0012] A further technical solution is that the guide rail is a guide slot plate, the guide slot plate is composed of a plurality of guide rail arrays, and the guide rail arrays are matched with different component sizes.

[0013] The technical solution also provided by the present invention is a method for automatically loading electronic components into a fixture, comprising the following operating steps performed in sequence: using a suction head to suck up the capacitor from a flexible vibration plate in a horizontal manner, correcting the direction and position of the component, moving the capacitor to the entrance of the guide rail and placing it down, the component sliding along the guide rail, gradually turning from an inclined direction to a steep slope, and finally falling into the positioning groove of the fixture in a vertical manner.

[0014] A further technical solution is that the guide rail and the fixture move relative to each other to load the components into the positioning slots in the fixture row by row, or the same number of rows of guide rails match the same number of rows of positioning slots to complete the operation of loading components into the fixture while the two remain relatively still.

[0015] A further technical solution is that for components of a specific size, a fixture of a corresponding size is selected, a guide slot plate is placed above the fixture, a guide slot array matching the size of the component is used, a row of positioning slots in the fixture is placed at the component exit of the guide slot array of the corresponding size, the suction head array places the component of the corresponding size at the component entrance of the selected corresponding guide slot array, and the component passes through the guide slot array and falls from the component exit into a row of positioning slots in the fixture; the guide rail array moves relative to the fixture, and the components are loaded into each positioning slot array in the fixture in a row-by-row manner. The so-called components of a specific size here refer to components of unconventional sizes.

[0016] The advantages and beneficial effects of the present invention are: no friction occurs between components, which can meet the needs of high requirements on appearance; in addition, the operation is convenient and simple for components of different sizes, and components whose electrodes are not on the smaller end surface but on the larger end surface can also be easily operated.

[0019] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] like Figures 1 to 3 As shown, the present invention is a device for automatically loading electronic components into a fixture, comprising a flexible vibration plate 1, a movable suction head 2, and a guide rail 3 that can turn components from horizontal to vertical, and the component outlet of the guide rail corresponds to the positioning groove 4 of the fixture. The movable suction head 2 is driven by a servo motor 7 to operate, and the suction head is used to suck up the capacitor from the flexible vibration plate in a horizontal manner, correct the direction and position of the component, move the capacitor to the entrance of the guide rail and put it down, and the component slides along the guide rail, gradually turning from an inclined direction to a steep slope, and finally falls into the positioning groove of the fixture in a vertical manner.

[0021] The guide rail has a certain inclination at its entrance and then gradually turns to vertical during the guiding process. A blocking surface 5 is provided on the outer side of the guide rail so that the component will not leave the guide rail during the guiding process.

[0022] The guide rail may be provided with a plurality of guide grooves of the same specification, corresponding to a plurality of positioning grooves of the same size in the fixture, so as to improve the efficiency of loading components into the fixture.

[0023] The guide rail can be provided with a plurality of guide rails of the same specification arranged in an array, corresponding to a plurality of positioning grooves of the same size arranged in an array in the fixture. The fixture can be provided with multiple rows of positioning grooves. The guide rail can move relative to the fixture to load components into the positioning grooves in the fixture row by row. Alternatively, multiple rows of guide rails can correspond to multiple rows of positioning grooves, and the operation of loading components into the fixture can be completed when the two remain relatively still.

[0024] The guide rails are composed of multiple guide rail arrays corresponding to different component sizes, which are called guide slot plates. For components of a specific size, a fixture of the corresponding size is selected, and the guide slot plate is placed above the fixture. A guide slot array of the corresponding size is used, and a row of positioning slots in the fixture corresponds to the exit of the guide slot array of the corresponding size. The suction head array places the components of the corresponding size at the entrance of the selected corresponding guide slot array. The components pass through the guide slot array and fall into a row of positioning slots of the fixture from its exit. The guide rail array moves relative to the fixture to load the components into each positioning slot array in the fixture in a row-by-row manner.

[0025] Of course, after the suction head sucks the component, the component is first placed on the loading and aligning plate 6 to ensure that multiple components are arranged in order. There are several placement grooves on the loading and aligning plate that are compatible with components of different sizes and specifications.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
