[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figure 1 , Figure 2, the present utility model provides a technical solution for a PCB board downloading device: including a PCB board lifting component 1 and a probe 2 as prior art; wherein the PCB board lifting component 1 includes a fixed bracket 12, a lifting plate 10, a placement groove 14 for placing the PCB board, and a cylinder 13; the placement groove 14 is arranged on the lifting plate 10, and the cylinder 13 drives the lifting plate 10 to rise to the fixed bracket 12; the probe 2 is installed on the fixed bracket 12, and the probe 2 is connected to the PCB board to perform program downloading;

[0022] Further, to improve the downloading efficiency; a plurality of the PCB board lifting components 1 are provided and are distributed in a circular array, and a rotating structure is arranged at the center of the array; the rotating structure includes a turntable 3 and a plurality of connecting arms 31; the plurality of connecting arms 31 are fixedly connected to the turntable 3, and the plurality of connecting arms 31 are respectively fixedly connected to their respective fixed brackets 12; the turntable 3 drives the PCB board lifting component 1 to rotate and change the position. Preferably, the turntable 3 is connected to a servo motor 32 for rotating the turntable 3.

[0023] Further, to facilitate the loading and unloading operations of the staff, a workbench 4 is arranged on one side of one of the PCB board lifting components 1.

[0024] Further, to enable the device to locate the workbench 4, a switch sensor 6 is provided on one side of each lifting plate 10, and an induction area 7 corresponding to the switch sensor 6 is provided on the workbench 4; when the switch sensor 6 senses the induction area 7, the servo motor 32 stops rotating, so that the current PCB board lifting component 1 corresponds to the workbench 4.

[0025] Further, to realize the automation of loading and unloading, the switch sensor 6, the cylinder 13, and the servo motor 32 are all controlled by a controller (not shown in the figure); the switch sensor 6 can adopt an existing infrared switch sensor and its matching infrared sensing part as the induction area; the controller receives the signal of the switch sensor 6, makes the piston of the cylinder 13 extend forward, and lowers the lifting plate 10; at this time, the worker can take out the downloaded PCB board and put in the PCB board to be downloaded. The electrical connections between the controller, the switch sensor 6, the cylinder 13, and the servo motor 32 belong to the conventional technical means of those skilled in the art and can be realized through simple programming and wiring, so it will not be elaborated in this specification.

[0026] Further, after placing the PCB board to be downloaded, the cylinder 13 needs to be reset so that the PCB board rises to be connected to the probe 2. Therefore, a travel switch 8 (the travel switch 8 is electrically connected to the controller) is arranged on the workbench 4 to start the cylinder 13 and make the cylinder 13 drive the lifting plate 10 to rise to the fixed bracket 12.

[0027] Further, to improve the rotation efficiency of the PCB board lifting assembly 1, an existing circuit linkage method is adopted. After the travel switch 8 is pressed, the piston of the cylinder 13 contracts and resets while the servo motor 32 starts simultaneously. Similarly, when the switch sensor 6 senses the sensing area 7, not only does the servo motor 32 stop, but also the cylinder 13 drives the lifting plate 10 to descend.

[0028] Further, since several PCB board lifting assemblies 1 are all involved in rotation, the PCB board lifting assembly 1 will be in a suspended state. Therefore, the cylinder 13 is installed on the fixed bracket 12, and the piston of the cylinder 13 penetrates the fixed bracket 12 to the lifting plate 10 to fix the lifting plate 10 by means of the cylinder 13.

[0029] Meanwhile, to enable the lifting plate 10 to rise accurately and the PCB board to be accurately connected to the probe 2, limit holes are fixed at the four corners of the lifting plate 10, and limit posts are fixed at the corresponding positions of the fixed bracket 12 corresponding to the limit holes. The limit posts are inserted into the limit holes; the rising path of the lifting plate 10 is limited by the limit holes and the limit posts.

[0030] Working principle: The worker places the PCB board to be downloaded in the placement groove 14 on the workbench 4, and then presses the travel switch 8 to contract the piston of the cylinder 13, and the PCB board is connected to the probe 2 to start the download transmission; meanwhile, the new PCB board lifting assembly 1 is driven by the turntable 3 to move to the workbench 4. When the switch sensor 6 senses the sensing area 7, the turntable 3 stops rotating, and the cylinder 13 drives the lifting plate 10 to descend, and the worker takes out the downloaded PCB board; and so on in repetition.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed claims.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
