[0038] In this embodiment, the storage component 1 and the clamping component 2 constitute the QFN packaged nail carrier transport device according to this application, realizing the transport of the QFN packaged nail carrier.

[0039] In this embodiment, the QFN package holder is a frame-like structure made of copper or alloy, used to support the chip and form electrical connections during the packaging process.

[0040] In this embodiment, a push rod is provided at the upper end of the fixed base plate 101 to push the QFN package pin holder to move, and a universal wheel (not shown) may be provided at the lower end of the fixed base plate 101 to drive the QFN package pin holder to move.

[0041] It should be noted that the door panel 103 is placed on the outer shell 102 by gravity, and a magnetic sealing strip is provided on the side of the door panel 103 that is placed on the outer shell 102.

[0042] Specifically, the lower end of the outer shell 102 is fixed to the fixed base plate 101, and the door panel 103 is rotatably connected to one side of the outer shell 102 via a rotating shaft. At the same time, the drive motor 104 is fixed to the other side of the outer shell 102 via a bracket. The threaded rod 105 is rotatably connected to the outer shell 102, and the threaded sleeve 106 is threadedly connected to the threaded rod 105. The lower end of the connecting block 107 is fixed to one side of the threaded sleeve 106, and the end of the connecting block 107 away from the threaded sleeve 106 is fixed to the placement plate 108. The sliding groove 109 is provided on the outer shell 102, and the slider 110 is slidably connected in the sliding groove 109. One side of the slider 110 is fixed to one side of the placement plate 108. The lower end of the fixed column 111 is fixed to the placement plate 108, and the roller 112 is rotatably connected to the fixed column 111 via a rotating shaft.

[0043] In a preferred embodiment, when the threaded rod 105 drives the threaded sleeve 106 to move, the connecting block 107 can drive the placement plate 108 to move, thereby causing the slider 110 to slide in the groove 109, preventing the threaded sleeve 106 from rotating with the threaded rod 105.

[0044] In a preferred embodiment, two sets of fixing columns 111 are symmetrically arranged, and when the placement plate 108 slides out from the outer shell 102, the door panel 103 can be opened by the provided rollers 112.

[0045] Specifically, the handle 202 is fixed to one side of the fixed clamping block 201, and the guide post 203 is fixed to the groove provided on the placement plate 108. The lower end of the fixed clamping block 201 is slidably connected to the guide post 203. One end of the first spring 204 is fixed to the groove provided on the placement plate 108, and the other end of the first spring 204 is fixed to the lower end of the fixed clamping block 201. The first spring 204 is sleeved on the guide post 203. One end of the second spring 205 is fixed to the groove provided on the fixed clamping block 201, and the other end of the second spring 205 is fixed to the sliding block 206. The sliding block 206 is slidably connected to the groove provided on the fixed clamping block 201. The end of the sliding block 206 away from the second spring 205 is fixed to the fixed clamping post 207. The fixed clamping post 207 is slidably connected to the fixed plate 208, and the fixed plate 208 is fixed to the groove provided on the fixed clamping block 201.

[0046] In a preferred embodiment, the lower end of the fixing block 201 is slidably connected to the guide post 203, and the first spring 204 is sleeved on the guide post 203, which can prevent the fixing block 201 from bending when it compresses the first spring 204.

[0047] It should be noted that there are two sets of fixed clamping blocks 201 symmetrically arranged, and the symmetrically arranged fixed clamping blocks 201 are fixed to the placement plate 108. The elastic force of the second spring 205 is less than that of the first spring 204, and the end of the fixed clamping column 207 used for clamping is provided with a rubber pad.

[0048] In use, when transporting the QFN packaged nail holder, the drive motor is started, which drives the threaded rod to rotate, thereby moving the connecting block through the threaded sleeve. This, in turn, causes the slider connected to the placement plate to slide outward in the groove. The outward sliding of the placement plate causes the rollers on the fixed column to push the door panel open from the outer shell. Then, the handle is manually pulled, which moves the fixed clamping block, causing it to slide on the guide column and compress the first spring to retract, placing the QFN packaged nail holder on the placement plate. When the handle is stopped, the rebound force of the first spring pushes the QFN packaged nail holder placed on the placement plate to clamp. When clamping the QFN packaged nail holder, the fixed clamping column first contacts the QFN packaged nail holder. The fixed clamping column is forced to press the sliding block to slide in the groove on the fixed clamping block, thereby causing the second spring to retract. This allows for clamping QFN packaged nail holders of different shapes.

[0049] The QFN package nail carrier transport device of this invention makes the placement and transport of QFN package nail carriers smoother and more efficient. It can also effectively prevent external factors such as dust and moisture from entering the housing, and avoid physical damage such as scratches and dents that may be caused by rigid clamping, thereby ensuring that the QFN package nail carrier maintains its original structural integrity during transportation.

[0050] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
