[0004] The lifting platform of this patent has a fixed size and can only place PCBs of a fixed size. If the size of the PCB changes, the lifting platform will be unable to adapt, thus reducing its applicability. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0030] To address the issue that a fixed-size lifting platform cannot be used with PCBs of different sizes, this embodiment provides an automatic loading and unloading mechanism for a PCB testing machine, such as... Figure 2 As shown, the device includes a support assembly 100, which can be driven to rise and fall (the driving method is shown in announcement number CN208297645U). The support assembly 100 has a first plate 110, which is square, as shown in announcement number CN208297645U. The top of the first plate 110 can be used to symmetrically place two PCB boards. The two symmetrical surfaces of the first plate 110 are provided with first sliding grooves 111, which are rectangular. A second plate 140 is slidably installed inside the first sliding grooves 111. The second plate 140 is rectangular. The second plate 140 is set to be able to move away from or close to each other, so that different accommodating spaces are formed between the first plate 110 and the second plate 140 to place PCB boards of different sizes, and it can be used for more PCB boards of various sizes. Specifically, the support assembly 100 also includes: a channel 112, a driving component 120, and a bidirectional lead screw 130.

[0031] The channel 112 is square and is located at the center of the first plate 110. The bidirectional lead screw 130 is cylindrical with two oppositely oriented threads on its outer wall. It is located in the channel 112 and passes through the first plate 110. Both ends of the bidirectional lead screw 130 extend into two first grooves 111, and the two oppositely oriented threads are respectively located in the two first grooves 111. The bidirectional lead screw 130 and the first plate 110 are rotatably connected by bearings. The driving component 120 is a knob located in the channel 112. The knob is fixed to the bidirectional lead screw 130, and the driving component 120 can drive the bidirectional lead screw 130 to rotate with the help of external force.

[0032] In its initial state, the support assembly 100 is as follows: Figure 1 As shown, the second plate 140 is completely housed within the first slide groove 111. When it is necessary to place PCBs of different sizes, the bidirectional lead screw 130 is rotated by the drive component 120. The bidirectional lead screw 130 drives the two second plates 140 to slide closer or further away along the two first slide grooves 111, thereby reducing or increasing the area formed between the first plate 110 and the second plate 140, so as to place PCBs of different sizes and improve the applicability of the device.

[0033] Because the coverage area of ​​the support assembly 100 has changed, in order to be compatible with other structures disclosed in announcement number CN208297645U, further solutions include, for example... Figure 1 As shown, the automatic loading and unloading mechanism of the PCB board testing machine also includes: a rear wall plate 200, a partition plate 300, and two limit components 400.

[0034] The partition 300 is prior art as described in CN208297645U and is used to separate PCB boards; the rear wall panel 200 is prior art as described in CN208297645U and is used to install the partition 300; the two limiting components 400 have two baffles 430, which are coupled to the support assembly 100. When the two second plates 140 move away from or towards each other, the two baffles 430 move away from or towards each other synchronously, thereby adapting to the size changes of the support assembly 100. Specifically, as follows... Figure 1 As shown, two second sliding grooves 210 are formed on the surface of the rear wall panel 200. The second sliding grooves 210 are rectangular, and partial structures of the two limiting components 400 are respectively disposed in the two second sliding grooves 210, as shown. Figure 3 As shown, the limiting component 400 also includes: a slide bar 410, a slider 420, and an elastic element 440.

[0035] The slide rod 410 is cylindrical with a smooth surface and is fixedly installed in the second slide groove 210. The slider 420 is square and is slidably installed in the second slide groove 210. The slider 420 is penetrated by the slide rod 410, and the baffle 430 is fixed to the slider 420. The elastic element 440 is a spring that is sleeved around the slide rod 410. The two ends of the spring are fixed to the second slide groove 210 and the slider 420, respectively. The spring is located on the side of the two sliders 420 that are far apart from each other. The elastic element 440 can push the two sliders 420 closer to each other through its own elasticity.

[0036] During the size adjustment of the support assembly 100, when the two second plates 140 move away from each other, they will contact the two baffles 430. As the two second plates 140 continue to move away, the two baffles 430 will be pushed away synchronously. At this time, the two baffles 430 will drive the two sliders 420 to slide along the slide bar 410 and the second slide groove 210 and move away from each other. Simultaneously, the elastic element 440 will be compressed. Conversely, when the two second plates 140 move closer to each other, the elastic element 440 will be released, and at the same time, it will push the sliders 420 and the baffles 430 to maintain contact with the second plates 140. This allows the baffles 430 to adapt to the size adjustment of the support assembly 100, improving the stability of the device. At the same time, due to the presence of the elastic element 440, in a further effect, the elastic element 440 can push the sliders 420 and the baffles 430 in sequence to clamp and fix the PCB board, improving the placement stability of the PCB board.

[0037] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
