Description

Technical Field

[0001] This utility model belongs to the field of screw fastening technology, specifically relating to a CCD detection device after screw fastening. Background Technology

[0002] A screw is a tool that uses the physical and mathematical principles of inclined planes, circular rotation, and friction to gradually tighten objects and machine parts. "Screw" is a general term for fasteners and is commonly used in everyday speech. Screws are indispensable industrial necessities in daily life: tiny screws are used in cameras, eyeglasses, watches, and electronics; general screws are used in televisions, electrical appliances, musical instruments, and furniture; large screws and nuts are used in engineering, construction, and bridges; and various sizes of screws are used in transportation equipment, airplanes, trams, and automobiles. Screws play a vital role in industry, and as long as industry exists on Earth, the function of screws will always be important. Screws are a common invention of human production and life over thousands of years. In terms of application, they are arguably humanity's greatest invention. The primary function of a screw is to connect two workpieces together, providing a fastening effect.

[0003] After screwing, inspection is required to check whether the screws meet the required standards. This inspection requires the use of a CCD camera. However, the existing inspection methods lack the function of fixing and clamping the workpiece. After inspecting one workpiece, it is necessary to remove the workpiece and then put it back on. This back-and-forth operation is inefficient and inconvenient. It is also not convenient to perform all-round inspection, and the inspection accuracy is low. Utility Model Content

[0004] The purpose of this utility model is to provide a CCD inspection device after screwing, so as to solve the problems mentioned in the background art, which require inspection after screwing to check whether the screwed screws meet the required standards. The inspection requires the use of a CCD camera, but the existing inspection methods lack the function of fixing and clamping the workpiece. After inspecting one, the workpiece needs to be removed and then placed back on, which is inefficient, inconvenient, and not suitable for all-round inspection, resulting in low inspection accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A CCD inspection device after screwing, comprising a lower base plate, on which a plurality of bolts are passed; a plurality of connecting plates, a bracket, and a motor are fixedly mounted on the upper surface of the lower base plate; a common upper top plate is fixedly mounted between the plurality of connecting plates; the output shaft of the motor rotatably passes through the upper top plate and is fixedly mounted on a rotating plate; a plurality of rotating shafts are rotatably mounted on the rotating plate; a bearing housing is fixedly mounted at the top of each rotating shaft; a drive motor is fixedly mounted on the side of the bearing housing; and a bidirectional screw is rotatably mounted inside the bearing housing. The rod has one end fixedly connected to the output shaft of the drive motor. Threaded plates are threaded onto the outer surfaces of both threaded sections of the bidirectional screw. Connecting plates are fixedly installed at both ends of the threaded plates. A clamping plate is fixedly installed between the two connecting plates. A channel for the connecting plates to move is provided on the side of the bearing housing. A servo motor is fixedly installed on the surface of the top plate. The servo motor works in conjunction with a rotating shaft. A cylinder is fixedly installed on the upper surface of the bracket. A sliding plate is fixedly installed at the end of the piston rod of the cylinder. The sliding plate is located inside the bracket, and a CCD camera is fixedly installed on its side.

[0006] The above scheme utilizes a carrier housing in conjunction with clamping plates. The relative movement of the two clamping plates is achieved by rotating a bidirectional screw within the carrier housing, thus securing the workpiece after screwing and ensuring stability during subsequent plate rotation. Multiple carrier housings on the plate, used in conjunction with a motor, enable position switching, allowing for simultaneous loading and inspection, effectively improving work efficiency. A servo motor, used in conjunction with a rotating shaft, enables the rotation of the fixed workpiece. A cylinder, used in conjunction with a sliding plate, allows for the vertical movement of the CCD camera, enabling omnidirectional inspection and improving the accuracy of the inspection operation.

[0007] In the above scheme, it should be noted that the motor, drive motor, servo motor, cylinder, CCD camera, and fill light strip are all electrically connected to an external power supply.

[0008] In a preferred embodiment, an annular track is fixedly installed on the surface of the top plate, and a plurality of track sliders are fixedly installed on the lower surface of the rotating plate, the track sliders being slidably installed on the inner wall of the annular track.

[0009] By adopting the above scheme, the sliding slider can be set to slide within the circular track, which can support the rotation of the rotating plate and effectively prevent the plate from tilting or swaying.

[0010] In a preferred embodiment, a second bevel gear is fixedly installed at the end of the output shaft of the servo motor, and a first bevel gear is fixedly installed at the bottom end of the rotating shaft. The first bevel gear and the second bevel gear cooperate with each other.

[0011] Using the above scheme, bevel gear one and bevel gear two are used in combination. When the rotating plate rotates to the point where bevel gear one and bevel gear two mesh, the servo motor will drive the rotating shaft to rotate the bearing housing through the meshing of bevel gear one and bevel gear two.

[0012] In a preferred embodiment, a plurality of guide rods are fixedly installed on the inner wall of the bearing housing, and the threaded plate is slidably installed on the outer surface of the plurality of guide rods.

[0013] By adopting the above scheme, the movement of the threaded plate can be guided by the guide rod, so that the threaded plate has good stability during the movement.

[0014] In a preferred embodiment, a plurality of guide bars are fixedly installed on the inner wall of the bracket, and a guide groove is provided on the side of the sliding plate. The guide bars and the guide groove are used in conjunction.

[0015] By using the above scheme, the guide bar and guide groove are used together to guide the up and down movement of the sliding plate, making the sliding plate move more smoothly under the action of the cylinder.

[0016] In one preferred embodiment, several supplementary lighting strips are fixedly installed on the side of the bracket.

[0017] Using the above solution, supplementary lighting strips can be activated to supplement brightness in low-light conditions, making it convenient for use in dim environments.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The CCD inspection device after screwing in the screws uses a carrier housing in conjunction with a clamping plate. The relative movement of the two clamping plates is achieved by rotating the bidirectional screw inside the carrier housing, thereby fixing and clamping the workpiece after screwing in the screws and ensuring stability during the subsequent rotation of the rotating plate. Multiple carrier housings on the rotating plate are used in conjunction with a motor to achieve position switching, achieving the effect of loading and inspecting at the same time, effectively improving work efficiency.

[0020] The CCD inspection device after screwing in the screws uses a servo motor in conjunction with a rotating shaft to rotate the workpiece after it is fixed, and uses a cylinder in conjunction with a sliding plate to move the CCD camera up and down, thereby enabling all-around inspection and improving the accuracy of the inspection operation.

One end of the bidirectional screw 11 is connected to the drive motor 10. The output shaft of the motor 10 is fixedly connected. Threaded plates 12 are threaded onto the outer surfaces of both ends of the threaded screw 11. Connecting plates 13 are fixedly installed at both ends of the threaded plates 12. A clamping plate 14 is fixedly installed between the two connecting plates 13. A channel for the connecting plates 13 to move is opened on the side of the bearing housing 9. A servo motor 15 is fixedly installed on the surface of the top plate 5. The servo motor 15 works in conjunction with the rotating shaft 8.

The sliding plate 17 is located inside the bracket 4, and a CCD camera 18 is fixedly installed on the side of the sliding plate 17.

[0027] By using the bearing housing 9 in conjunction with the clamping plate 14, the relative movement of the two clamping plates 14 is achieved by rotating the bidirectional screw 11 inside the bearing housing 9, thereby fixing and clamping the workpiece after screwing, ensuring stability during the subsequent rotation of the rotating plate 7. The multiple bearing housings 9 on the rotating plate 7 are used in conjunction with the motor 6 to achieve position switching, achieving the effect of loading and inspecting at the same time, effectively improving work efficiency. By using the servo motor 15 in conjunction with the rotating shaft 8, the rotation of the fixed workpiece is achieved. By using the cylinder 16 in conjunction with the sliding plate 17, the up and down movement of the CCD camera 18 is achieved, thereby realizing all-round inspection and improving the accuracy of inspection operations.

[0028] A ring track 19 is fixedly installed on the surface of the top plate 5, and several track sliders 20 are fixedly installed on the lower surface of the rotating plate 7. The track sliders 20 are slidably installed on the inner wall of the ring track 19.

[0029] A bevel gear 22 is fixedly mounted on the output shaft end of the servo motor 15, and a bevel gear 21 is fixedly mounted on the bottom end of the rotating shaft 8. The bevel gear 21 and the bevel gear 22 work together. When the rotating plate 7 rotates to the point where the bevel gear 21 and the bevel gear 22 mesh, the servo motor 15 will drive the rotating shaft 8 to rotate the bearing housing 9 through the meshing of the bevel gear 21 and the bevel gear 22.

[0030] Several guide rods 23 are fixedly installed on the inner wall of the bearing housing 9. The threaded plate 12 is slidably installed on the outer surface of the guide rods 23. The guide rods 23 can be used to guide the movement of the threaded plate 12, so that the threaded plate 12 has good stability during the movement.

[0031] Several guide bars 24 are fixedly installed on the inner wall of the bracket 4. A guide groove is provided on the side of the sliding plate 17. The guide bars 24 and the guide groove work together to guide the up and down movement of the sliding plate 17, making the sliding plate 17 move more smoothly under the action of the cylinder 16.

[0032] Several supplementary light strips 25 are fixedly installed on the side of the bracket 4. When the ambient light is low, the supplementary light strips 25 can be activated to supplement the brightness, making it convenient for use in dim environments.

[0033] In use, first install the lower base plate 1 using bolts 2. After installation, place the workpiece with the screws tightened on the bearing housing 9. Start the drive motor 10 to drive the bidirectional screw 11 to rotate, which in turn drives the threaded plate 12 to move the connecting plate 13, thereby moving the clamping plate 14. The workpiece is fixed and clamped by the movement of the clamping plate 14. Then, start the motor 6 to drive the rotating plate 7 to rotate, which in turn drives the fixed workpiece to rotate. When the workpiece rotates to the position where the CCD camera 18 is located, stop the motor 6. At this time, bevel gear 1 21 and bevel gear 2 22 mesh, and the CCD camera 18 is used to take pictures and detect the workpiece. At the same time, the servo motor 15 and the cylinder 16 work. The servo motor 15 drives the rotating shaft 8 to rotate through bevel gear 1 21 and bevel gear 2 22. The rotating shaft 8 drives the bearing housing 9 to rotate, which in turn drives the workpiece to rotate. At the same time, the cylinder 16 drives the sliding plate 17 to move the CCD camera 18 up and down, thereby realizing all-round detection. At the same time, when working in a dim environment, the supplementary light strip 25 is activated to supplement the brightness of the space.
