[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0023] Reference Figures 1 to 3 As shown, a screw gluing detection device described in an embodiment of the present invention includes a detection platform 1; a motor 11 is fixedly connected to the bottom of the detection platform 1; a rotating shaft 12 is fixedly connected to the output end of the motor 11; a fixing sleeve 13 is fixedly connected to the end of the rotating shaft 12; a fixing frame 14 is fixedly connected to the top of the detection platform 1; a first electric push rod 15 is fixedly connected to the side wall of the fixing frame 14; the end of the first electric push rod 15 is rotatably connected to a fixing plate 16; a detection component is fixedly connected to the side wall of the fixing frame 14; when working, when detecting the gluing of the screw, the screw head is placed in the fixing sleeve 13 to make the screw in a vertical state, and then the first electric push rod 15 is started to drive the fixing plate 16 to move toward the screw end of the screw, and when the fixing plate 16 and the screw end are fixed, the fixing plate 16 is rotated and connected to the screw end. After the parts are in contact, they can cooperate with the first electric push rod 15 to clamp and fix the screw from both ends, and then start the motor 11 to drive the fixing sleeve 13 to rotate. At this time, the screw and the fixing plate 16 can be driven to rotate at the same time. Then, the detection component can be used to detect whether the paint surface of the screw is qualified. In this step, the first electric push rod 15 is set to drive the fixing plate 16 to move toward the screw end of the screw, which can cooperate with the fixing sleeve 13 below to clamp and fix the screw. When the moving distance of the first electric push rod 15 is different, screws of different lengths can be clamped and fixed, reducing the need to replace the fixing structure when replacing screws of different lengths for detection to improve applicability. At the same time, the motor 11 drives the fixing sleeve 13 and the screw to rotate, which makes it easy to switch the detection surface and improves the convenience of detection.

[0024] Reference Figure 3As shown, the detection component includes a second electric push rod 2; the second electric push rod 2 is fixed to the side wall of the fixing frame 14; the end of the second electric push rod 2 is fixed with a connecting block 21; the bottom of the connecting block 21 is fixed with a camera 22; the top of the detection platform 1 is fixed with a display 23; during operation, after the screw is fixed in position, the second electric push rod 2 is started to drive the connecting block 21 and the camera 22 to move toward the screw below. When the camera 22 is parallel to the glue on the surface of the screw, the camera 22 is started to detect the surface of the screw and then display the data on the display 23. When the paint surface is detected to be unqualified, the display 23 will issue an alarm. In this step, the second electric push rod 2 is set to drive the camera 22 to cooperate with the display 23 to automatically detect the paint surface of the screw. The second electric push rod 2 drives the camera 22 to move, which makes it easy to adjust the height of the camera 22 to adapt to screw paint surfaces of different lengths, so as to improve the convenience and applicability of screw paint surface detection.

[0025] Reference Figures 1 to 2 As shown, the side wall of the fixing sleeve 13 is provided with a plurality of sliding holes 3; the inner wall of the sliding hole 3 is slidably connected to the spring rod 31; during operation, when the screw head is placed in the fixing sleeve 13, the end of the spring rod 31 will contact the surface of the screw head, and at this time the spring rod 31 will produce tension and generate a rebound force on the surface of the screw head, which can clamp and fix the screw head from the side. In this step, the spring rod 31 is arranged to contact the side of the screw head to generate tension and rebound force, and the side of the movable screw head is clamped and fixed. When the size of the screw head is different, the stretching distance of the spring rod 31 will also change accordingly, and screw heads of different sizes can be clamped and fixed to improve the applicability during fixation.

[0026] Reference Figure 3 As shown, the side wall of the connecting block 21 is fixedly connected with a light board 4; a plurality of lamp beads 41 are provided in the middle of the light board 4; during operation, when the connecting block 21 drives the camera 22 to move toward the screw, it will drive the light board 4 and the lamp beads 41 to move toward the screw at the same time, and then turn on the lamp beads 41. At this time, the lamp beads 41 and the camera 22 are set on the same side to illuminate the surface of the screw. When the light is insufficient, fill light can be used during detection. This step can fill light on the surface of the screw when the light is insufficient during detection by setting the light board 4 and the lamp beads 41 to be connected to the connecting block 21, thereby reducing the situation where the image taken by the camera 22 is unclear when the light is insufficient, thereby improving the clarity of the camera 22 in detecting the glue coating on the screw surface and improving the accuracy of the detection.

[0027] Reference Figure 3As shown, a pair of connecting rods 5 are fixedly connected to the side wall of the connecting block 21; the pair of connecting rods 5 are symmetrically arranged; a reflector 51 is hinged at the middle of the connecting rod 5; during operation, when the connecting block 21 drives the camera 22 to move toward the screw, it will simultaneously drive the connecting rod 5 and the reflector 51 to move toward the screw. At this time, the reflector 51 is rotated so that its reflecting surface is parallel to the screw. When the lamp bead 41 irradiates the screw, the scattered light will pass through the reflector 51 and then toward the surface of the screw. In this step, by setting the connecting block 21 to connect the connecting rod 5 and the reflector 51, the light scattered by the lamp bead 41 can be reflected to the surface of the screw, so that the light emitted by the lamp bead 41 can be more concentrated to improve the fill light effect on the screw.

[0028] Reference Figure 3 As shown, the side wall of the fixing frame 14 is fixedly connected to an air pump 6; the bottom of the air pump 6 is connected to a hose 61; the end of the hose 61 is connected to an air outlet pipe 62; a plurality of air outlet holes 63 are provided at the bottom of the air outlet pipe 62; the air outlet pipe 62 is fixedly connected to the top of the connecting rod 5; when working, the air pump 6 is started to drive the air flow into the hose 61 and then into the air outlet pipe 62 and finally ejected from the air outlet hole 63. The air outlet pipe 62 has an annular structure and can blow air to the camera 22 and the lamp bead 41 below at the same time. In this step, the camera 22 and the lamp bead 41 can be blown at the same time by setting a hose 61 to connect the air pump 6 and the air outlet pipe 62, which can reduce the situation where dust adheres to the surface of the camera 22 and causes unclear shooting. When blowing air to the lamp bead 41, the heat of the lamp bead 41 can be dissipated to improve the stability of the lamp bead 41 during operation.

[0029] Reference Figure 1 and Figure 4 As shown, the side wall of the inspection table 1 is fixedly connected to a collection box 7; a sponge pad 71 is fixedly connected to the collection box 7; during operation, when an unqualified screw is detected, the screw is removed from the fixing sleeve 13 and then placed in the collection box 7, and the unqualified screws can be collected at this time. This step can collect screws with unqualified glue coating by setting up the collection box 7, which can improve the convenience of collecting unqualified screws. At the same time, the sponge pad 71 is located at the bottom of the collection box 7 to reduce the wear caused by the contact between the screw and the bottom of the collection box 7.

[0030] Reference Figure 2 As shown, the end of the spring rod 31 is fixedly connected to a rubber plate 8; the rubber plate 8 is square in shape; during operation, when the spring rod 31 is clamped and fixed from the side of the screw head, the rubber plate 8 will contact the side of the screw head. In this step, by arranging the rubber plate 8 to connect the spring rod 31, the rubber plate 8 can contact the side of the screw head when the spring rod 31 clamps and fixes the screw head, thereby reducing the wear caused by the contact between the end of the spring rod 31 and the side of the screw head and increasing the friction between the spring rod 31 and the screw head.

[0031] During operation, when inspecting the glue coating on the screw, the screw head is placed in the fixing sleeve 13 so that the screw is in a vertical state, and then the first electric push rod 15 is started to drive the fixing plate 16 to move toward the screw end of the screw. When the fixing plate 16 contacts the screw end, it can cooperate with the first electric push rod 15 to clamp and fix the screw from both ends, and then the motor 11 is started to drive the fixing sleeve 13 to rotate. At this time, the screw and the fixing plate 16 can be driven to rotate at the same time. Then the detection component can be used to detect whether the paint surface of the screw is qualified. After the screw is fixed in position, the second electric push rod 2 is started to drive the connecting block 21 and the camera 22 to move toward the screw below. When the camera 22 is parallel to the glue coating on the screw surface, the camera 22 is started to detect the screw surface and then the data is displayed on the display 23. When it is detected that the paint surface is unqualified, the display 23 will sound an alarm. When the screw head is placed in the fixing sleeve 13, the end of the spring rod 31 will contact the screw head surface. At this time, the spring rod 31 will produce tension and generate a rebound force on the screw head surface, which can be used to inspect the screw head from the side. Clamp and fix, when the connecting block 21 drives the camera 22 to move toward the screw, it will drive the light board 4 and the lamp bead 41 to move toward the screw at the same time, and then turn on the lamp bead 41. At this time, the lamp bead 41 and the camera 22 are set on the same side to illuminate the surface of the screw. When the light is insufficient, it can be used for fill light during detection. When the connecting block 21 drives the camera 22 to move toward the screw, it will also drive the connecting rod 5 and the reflector 51 to move toward the screw. At this time, rotate the reflector 51 so that its reflecting surface is parallel to the screw. When the lamp bead 41 illuminates the screw, it will disperse the light. The emitted light will pass through the reflector 51 and then toward the surface of the screw, starting the air pump 6 to drive the air flow into the hose 61 and then into the air outlet pipe 62 and finally be ejected from the air outlet 63. The air outlet pipe 62 has a ring structure and can blow air to the camera 22 and the lamp bead 41 below at the same time. When an unqualified screw is detected, the screw is removed from the fixing sleeve 13 and then placed in the collection box 7. At this time, the unqualified screws can be collected, and when the spring rod 31 is clamped and fixed from the side of the screw head, the rubber plate 8 will contact the side of the screw head.

[0032] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
