[0015] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0016] In an embodiment of the present utility model, Figure 1 , Figure 2 and Figure 3 It is a schematic diagram of corresponding components provided according to the specific structure of a test tray for plastic-sealed devices of the utility model, such as Figure 1 and Figure 2 As shown, the utility model specifically comprises: a tray body 1, a nozzle connector 3 and a nozzle 2, a vacuum hole 11 is provided on the front of the tray body 1, one end of the nozzle connector 3 is detachably connected to the vacuum hole 11, the other end of the nozzle connector 3 is detachably connected to the nozzle 2, and a sealing ring 4 is provided between the nozzle connector 3 and the tray body 1. Handles 13 are provided on both sides of the tray body 1.

[0017] The utility model can lift the plastic-encapsulated component by arranging the suction nozzle connector 3 and the suction nozzle 2 on the vacuum hole 11 to prevent the pins of the plastic-encapsulated component from directly contacting the tray. At the same time, the plastic-encapsulated component is fixed by the suction nozzle 2 to prevent scratches and damages to the pins.

[0018] In one embodiment of the utility model, a vacuum channel 14 is provided inside the tray body 1, and vacuum holes 12 are provided on both sides of the tray body 1, the vacuum holes 12 are connected to the vacuum channel 14, and the vacuum holes 11 are connected to the vacuum channel 14. Negative pressure is continuously applied to the vacuum channel through the vacuum holes 12 on both sides of the tray, so that continuous suction is obtained at the vacuum holes 11. The specific arrangement of the vacuum holes 11 and the vacuum channel can be as follows: Figure 3 The positions of the vacuum holes 11 and the vacuum channels can be changed according to actual test needs in the same manner as the horizontal and vertical cross arrangement. Meanwhile, the number of the vacuum holes 11 can also be determined according to actual needs and is not limited here.

[0019] In one embodiment of the utility model, the nozzle connector 3 includes a connecting tube 31 and a limiting ring 32. The limiting ring 32 is arranged on the outer wall of the connecting tube 31. The outer wall of the connecting tube 31 is provided with an external thread 33. The external thread 33 is located on one side of the limiting ring 32. The vacuum hole 11 is provided with an internal thread matched with the external thread 33. The nozzle connector 3 is detachably connected to the vacuum hole 11 by screwing the connecting tube 31 into the vacuum hole 11. The limiting ring 32 limits the position of the connecting tube 31 to prevent the entire connecting tube 31 from falling into the vacuum channel 14. At the same time, a sealing ring 4 is arranged between the limiting ring 32 and the tray to prevent the vacuum hole 11 from leaking and improve the adsorption effect. The sealing ring 4 can be a rubber gasket.

[0020] The end surface of the suction nozzle 2 facing away from the suction nozzle connector 3 is arranged horizontally, so as to ensure that the plastic-encapsulated component is placed horizontally when being adsorbed, thereby improving the efficiency of detection. Figure 1 As shown, the corners are removed from the end face of the suction nozzle 2, so that the cross section of the suction nozzle 2 is a rectangular shape with the two top corners removed, which can effectively prevent the corners from scratching the plastic-encapsulated device. The suction nozzle 2 is sleeved on the end of the connecting tube 31 away from the external thread 33. The suction nozzle 2 is fixed by sleeve arrangement, which can realize the detachable connection of the suction nozzle 2. When actually needed, the suction nozzle 2 is replaced according to the size of the plastic-encapsulated device to ensure that the suction nozzle 2 can cover the plastic-encapsulated device. An air suction channel 21 is opened in the center of the suction nozzle 2. The diameter of the air suction channel 21 is smaller than the inner diameter of the connecting tube 31. Since the diameter of the air suction channel 21 is smaller than the inner diameter of the connecting tube 31, the flow rate of the air in the air suction channel 21 can be increased, thereby improving the adsorption force. In order to ensure that the suction nozzle 2 does not damage the surface of the plastic-encapsulated device, the suction nozzle 2 can be made of silicone material.

[0021] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
