This quality inspection step is usually carried out manually. There are problems such as a large amount of work, long required time, low inspection efficiency, etc. when manually checking whether the key is installed in place, and it is easy to miss inspections. It is easy to make mistakes just by relying on the human eye to identify whether the key is installed in place. At the same time, due to the low quality inspection efficiency of the key, it will affect the assembly efficiency of other subsequent accessories. Content of the Utility Model

[0005] A lifting plate capable of moving up and down, and a reference plate is arranged above the lifting plate;

[0006] A pressing plate, the pressing plate is fixedly connected to the reference plate through a guide rod, the guide rod is slidably connected to the lifting plate up and down, and a cavity adapted to the outer shape of the product to be detected is formed on the bottom surface of the pressing plate;

[0007] A detection mechanism, which is arranged above the reference plate and can detect the distance between the upper surface of the reference plate and the lower surface of the detection mechanism.

[0008] Preferably, it further includes a support frame and a lifting module vertically fixed on the support frame, and the lifting plate is installed on the lifting module.

[0009] Preferably, a vertical plate is arranged on the lifting plate, a fixing member is arranged on the vertical plate, and the detection mechanism is fixedly installed on the fixing member.

[0010] Preferably, the detection mechanism uses a laser rangefinder.

[0011] Preferably, a buffer spring is arranged on the guide rod, and the buffer spring is located between the lifting plate and the pressing plate.

[0012] Preferably, guide rods are provided at both ends of the reference plate. The upper ends of the guide rods are slidably connected to the reference plate up and down, and the lower ends are fixedly connected to the lifting plate.

Specific Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] Such as Figure 1 、 Figure 2As shown in the figure, a preferred embodiment of the present utility model provides a key assembly detection device, which mainly consists of components such as a lifting module 2, a lifting plate 3, a pressing plate 5, a reference plate 4, and a detection mechanism 8. Among them, the lifting module 2 uses a cylinder, which is vertically fixed on the support frame 1 and is used to control the downward pressure of the pressing plate 5. The lifting plate 3 is horizontally arranged and fixedly connected to the output end of the cylinder. The reference plate 4 and the pressing plate 5 are respectively located on the upper and lower sides of the lifting plate 3, and the reference plate 4 and the pressing plate 5 are connected by four guide rods 9. The guide rods 9 are slidably connected to the lifting plate 3 up and down, and the upper and lower ends of the guide rods 9 are respectively fixed on the reference plate 4 and the pressing plate 5.

[0023] A buffer spring 10 is provided on each guide rod 9. The buffer spring 10 is located between the lifting plate 3 and the pressing plate 5, provides a pre-tightening force to the pressing plate 5, and plays a buffering role when being compressed. A cavity 501 is formed on the bottom surface of the pressing plate 5, and the outer shape of the cavity 501 is adapted to the outer shapes of the product and the key installed on the product. When the pressing plate 5 presses down, the product and the key can be accommodated in the cavity 501.

[0024] Guide rods 9 are provided at both ends of the reference plate 4 to play a guiding role. The upper end of the guide rod 9 is slidably connected to the reference plate 4 up and down, and the lower end is fixed on the lifting plate 3. When the pressing plate 5 presses down, the reference plate 4 will move up and down together with the pressing plate 5.

[0025] A vertical fixed plate 6 is provided on the lifting plate 3. The fixed plate 6 is located on the side of the lifting module 2, and a fixing member 7 is provided on the fixed plate 6 for installing the detection mechanism 8. In this embodiment, the detection mechanism 8 uses a laser rangefinder, and the laser rangefinder can detect the distance between the reference plate 4 and itself.

[0026] In other technical solutions, the detection mechanism 8 can also use a sensor or other position measuring devices.

[0027] The upper surface of the reference plate 4 is a plane and can reflect the laser emitted by the laser rangefinder. After receiving the laser signal reflected by the reference plate 4, the laser rangefinder will automatically calculate the distance to the reference plate 4.

[0028] Reference Figure 2 、 Figure 3 In order to ensure that the pressing plate 5 can accurately align with the product, a positioning rod 11 is provided on one side of the bottom of the lifting plate 3, and at the same time, an avoidance groove 502 is provided on one side of the pressing plate 5 to cooperate with the positioning rod 11. The lower end of the positioning rod 11 passes through the avoidance groove 502.

[0029] When the lifting module 2 controls the lifting plate 3 to move downward, the reference plate 4 and the pressing plate 5 will move downward with the lifting plate 3. At this time, the positioning rod 11 is inserted into the corresponding position on the jig plate 12 below which the product is loaded. Then the lifting plate 3 continues to move downward, and the pressing plate 5 and the reference plate 4 move downward together. The lower surface of the pressing plate 5 will contact the product on the jig plate 12, and the product and the button will be embedded in the cavity 501 on the bottom surface of the pressing plate 5. The cavity 501 fits the product and the button perfectly, and the distance between the laser rangefinder and the reference plate 4 reaches the set value, indicating that the button is installed in place. If the button on the product is not installed in place, the button will tilt upward. At this time, the product and the button cannot be completely embedded in the cavity 501. At this time, the pressing plate 5 cannot continue to press down, and the distance between the reference plate 4 and the laser rangefinder will change, so that it can be detected that the button on the product is not installed in place.

[0030] When the pressing plate 5 is pressed downward, the buffer spring 10 will be compressed by force, playing a buffering role to prevent the pressing plate 5 from damaging the product and the button.

[0031] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
