[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0019] As Figure 1-2 shown, a screw anti-fool detection device according to an embodiment of the present utility model includes an upper electrode 2 fixedly connected to welding equipment 12 and a main body bracket. The main body bracket includes a connecting plate 14 and an L-shaped connecting plate 13. A height adjusting screw is provided at the top of the main body bracket. The height adjusting screw is connected to an adjusting screw 1, and the adjusting screw 1 is connected to the L-shaped connecting plate 13. A corresponding lower electrode 11 is provided below the upper electrode 2;

[0020] The back of the upper electrode 2 is connected to one end of the connecting plate 14, the other end of the connecting plate 14 is fixedly connected to the L-shaped connecting plate 13, the horizontal plate of the L-shaped connecting plate 13 is connected to the sliding rod 6 through a bearing, the bottom end of the sliding rod 6 is fixedly connected to the pressure plate 7, the upper part of the sliding rod 6 is fixedly connected to the induction plate 3, the right side of the induction plate 3 is the vertical plate of the L-shaped connecting plate 13, an upper inductor 4 and a lower inductor 5 are arranged between the induction plate 3 and the vertical plate, the upper inductor 4 and the lower inductor 5 are fixedly arranged side by side on the vertical plate, and the position of the induction plate 3 matches the positions of the upper inductor 4 and the lower inductor 5.

[0021] The upper inductor 4 and the lower inductor 5 are connected to the PLC controller. The adjusting screw 1 is vertically connected to the horizontal plate of the L-shaped connecting plate 13. There are two sliding rods 6.

[0022] The lower electrode 11 is located above the welding fixture. The descent of the upper electrode 2 is driven by a cylinder.

[0024] In order to facilitate the understanding of the above technical solution of the present invention, the above technical solution of the present invention will be described in detail below through specific usage modes.

The specific solution measures are as follows: Place the product at the lower electrode 11, start the button, the upper electrode 2 connected to the cylinder descends, and the screw detection device descends synchronously. When the upper electrode 2 descends in place and the pressure plate 7 fits with the screw 9, the sliding rod 6 rises and the induction plate 3 rises synchronously. If the height of the screw 9 is normal, the signal lights of the upper inductor 4 and the lower inductor 5 light up simultaneously; if the height of the screw 9 is too low and the induction plate does not rise enough, the upper inductor 4 lights up and the lower inductor does not light up, and the device alarms and cannot perform the next action; if the screw 9 is too high and the induction plate 3 rises too high, the lower inductor 5 lights up and the upper inductor 4 does not light up, and the device alarms and cannot perform the next action. The specifications of the screw 9 are diverse, and the correct position of the induction plate is manually adjusted by the adjusting rod 1.

[0027] In summary, by means of the above technical solution of the present utility model, the screws on the product are detected through the cooperation of the induction plate and the inductor to determine the height of the screws on the product, so as to determine whether the screws on the product are used correctly, greatly improving the qualified rate of the product, reducing the rework rate of the product, and also greatly improving the production work efficiency.
