[0002] A rectifier bridge is a packaged device that uses the unidirectional conduction characteristic of diodes to convert alternating current (AC) to direct current (DC), and it is widely used in the electronics field. After production, rectifier bridges require performance testing to prevent substandard performance from causing further damage to circuits. Traditional rectifier bridge performance testing is mostly done manually, which is inefficient and costly. Therefore, automated testing equipment, such as the one shown in authorization announcement number CN211937977U, has emerged. However, existing testing methods mostly involve manually placing the rectifier bridge on a conveyor belt or other transport structure and then transporting it to a designated location for testing. This manual placement process is still time-consuming, labor-intensive, and requires personnel supervision, presenting inconvenience. Therefore, there is a need for a testing device for rectifier devices that can automatically feed materials and facilitate testing. Summary of the Invention

Detailed Implementation

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] Example 1:

[0028] like Figures 1-4As shown, a testing device for rectifier devices includes a testing device 1 for testing the performance of rectifier devices. The testing device 1 tests whether the diodes inside the rectifier device are connected by connecting to the exposed electrodes on the rectifier device. It also includes a material tray 2 for holding rectifier devices in rows, a motion device 3 for transporting the material tray 2, a testing channel 4, and a conveyor belt 5. The material tray 2 is disposed on the reciprocating motion device 3, and the material tray 2 is provided with a plurality of device slots 21 arranged side by side. When the material tray 2 reciprocates with the motion device, one of the plurality of device slots 21 is opposite to the testing channel 4. Both the detection channel 4 and the material tray 2 are inclined, and in this example, they are both inclined at an angle of approximately 45°, so that the rectifier can be subjected to gravity and slide down along the device groove 21 and the detection channel 4. The material tray 2 is located at the upper entrance of the detection channel 4. At least one detection device 1 is also provided on the side of the detection channel 4. In this example, two detection devices 1 are provided on the side of the detection channel 4, which are used to detect different parameters of the rectifier. The lower exit of the detection channel 4 is connected to the conveyor belt 5, so that the rectifier that has completed the test can be transported to the designated location along the conveyor belt 5.

[0029] The device slots 21 on the carrier tray 2 are closed at one end and open at the other. The open end of the device slot 21 faces the detection channel 4. Several ventilation holes 22 penetrating the carrier tray 2 are provided at the bottom of the device slot 21 to prevent the rectifier devices from being adsorbed in the device slot 21 due to low pressure. The motion device 3 includes a servo motor 31 and a ball screw structure 32, which are connected to the servo motor 31. The carrier tray 2 is detachably mounted on the slider of the ball screw structure 32. When the carrier tray 2 moves with the motion device 3, the device slots 21 on the carrier tray 2 are sequentially connected to the detection channel 4, allowing multiple rectifier devices placed in the corresponding device slots 21 to enter the detection channel 4. The overall shape of the carrier tray 2 is square. Upward-protruding blocking blocks for limiting the movement are provided on both sides of the slider of the ball screw structure 32, which facilitates the carrier tray 2 to be embedded between the two blocking blocks, allowing the carrier tray 2 to move with the slider.

[0030] The detection channel 4 includes a through groove 41 and a screening structure 42. The through groove 41 is used to transport devices. The through groove 41 is segmented, and adjacent through grooves 41 are connected by the screening structure 42. The screening structure 42 is correspondingly arranged below the detection device 1. For rectifier devices that fail the test, they are directly sent out of the detection channel 4 through the screening structure 42. It should be noted that the width of the through groove 41 corresponds to the rectifier device to ensure that the rectifier devices in the through groove 41 do not pass side by side. The screening structure 42 includes a pusher cylinder 421, a pusher groove 422, and a waste box 423. The pusher groove 422 is located between the two segments of the through groove 41 and is set at the movable end of the pusher cylinder 421. The waste box 423 is arranged adjacent to the through groove 41 and also corresponds to the pusher groove 422.

[0031] A baffle 43 is provided at one end of the through groove 41 near the device slot 21. The baffle 43 is located on one or both sides of the through groove 41 and is used to block the devices in the corresponding device slot 21 in the material tray 2, so as to prevent the rectifier devices in the device slot 21 that are not opposite to the through groove 41 from sliding out of the device slot 21 due to gravity.

[0032] The detection channel 4 is also provided with a blocking structure 44; the blocking structure 44 includes a baffle cylinder 441 and a baffle plate 442; the baffle plate 442 is disposed at the movable end of the baffle cylinder 441; in this example, the blocking structure 44 includes two forms, one is a blocking structure 44 disposed on the side of the detection channel 4, and the other is a blocking structure 44 disposed below the detection channel 4. The baffle plate 442 of both blocking structures 44 is located inside the detection channel 4, forming a blockage for the rectifier devices inside the detection channel 4. The blocking structure 44 is disposed at the end of the detection channel 4 near the material tray 2, and is used to block the devices in the device slot 21 to prevent excessive accumulation of rectifier devices in the detection channel 4. A blocking structure 44 is also provided in the area corresponding to the detection device 1 within the detection channel 4. Specifically, the blocking structure 44 is located in the areas in front of and behind the detection device 1. The blocking structure 44 in front of the detection device 1 is used to control the rectifiers entering the corresponding area of ​​the detection device 1, and the blocking structure 44 behind the detection device 1 is used to control the rectifiers exiting the area. By blocking the rectifiers, the detection device 1 can easily perform tests. The blocking structure 44 is also provided between the through groove 41 and the screening structure 42. It blocks the rectifiers that have completed the test, making it easier to push unqualified rectifiers into the waste box 423. For qualified rectifiers, the blocking structure 44 is opened, allowing them to continue sliding down the detection channel 4.

[0033] During implementation, by setting up an inclined detection channel 4 and a material tray 2, the rectifiers slide and are transported within the detection channel 4 under the influence of gravity. Simultaneously, the material tray 2 can integrate multiple rectifiers for convenient transport, and sequentially transports rectifiers from different device slots 21 to the detection channel 4, improving detection efficiency. The motion device 3, including a servo motor 31 and a ball screw structure 32, facilitates control of the stopping position of the material tray 2, ensuring that the device slots 21 on the material tray 2 are aligned with the detection channel 4. A screening structure 42 is used to remove unqualified rectifiers. A blocking structure 44 controls the stopping position of the rectifiers within the detection channel 4, facilitating detection and removal operations.

[0034] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
