[0020] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Such as Figure 1 and Figure 2 and Figure 3As shown in the figure, a visual inspection and automatic locking device for a screwdriver machine includes a feeding component 1, an optical camera component 2, an electric screwdriver locking module 3, a feeding component 4, and a chassis 5. The feeding component 1, the optical camera component 2, the electric screwdriver locking module 3, and the feeding component 4 are all arranged inside the chassis 5. The chassis 5 has an operation port 51, and the operation port 51 facilitates manual disassembly and assembly of products. A safety grating 52 is also arranged on the chassis 5, and the safety grating 52 is located at the operation port 51. When the device is running normally, if any object passes through the safety grating 52, the safety grating 52 will issue an alarm. Among them, the feeding component 1, the optical camera component 2, the electric screwdriver locking module 3, and the feeding component 4 are all signal-connected to the PLC controller, and the PLC controller is not shown in the figure.

[0022] The feeding component 1 includes a linear module 11, a fixture plate 12, and a cover plate 13. The linear module 11 is laid flat inside the chassis 5. The fixture plate 12 is slidably arranged on the linear module 11. The fixture plate 12 is used to place products. The cover plate 13 is rotatably arranged on the fixture plate 12. After the product is placed on the fixture plate 12, rotate the cover plate 13 to cover the product. In this way, when the linear module 11 drives the fixture plate 12 to move, the product and the cover plate 13 move together. The cover plate 13 makes the product more stable on the fixture plate 12, and the position of the product on the fixture plate 12 remains unchanged. The linear module 11 indirectly drives the product to the operation range of the electric screwdriver locking module 3. The linear module 11 is signal-connected to the PLC controller.

[0023] The two-coordinate moving platform 31 includes a vertical axis 311 and a horizontal axis 312. The horizontal axis 312 is arranged on the chassis 5. The vertical axis 311 is movably arranged on the horizontal axis 312. The electric screwdriver 32 is movably arranged on the vertical axis 311. The linear module 11 is located below the two-coordinate moving platform 31 and the electric screwdriver 32. The vertical axis 311 carries the electric screwdriver 32 to move horizontally on the horizontal axis 312. The electric screwdriver 32 can rise or fall on the vertical axis 311. The product on the linear module 11 is within the adsorption or release range of the bit 33.

[0024] As Figure 4 and Figure 5 As shown in the figure, a plurality of curved grooves 14 with curved surfaces are arranged on the cover plate 13. The bottom of the curved groove 14 has a through hole 15. The through hole 15 is used to dock with the threaded hole on the product. The curved groove 14 can enable the camera 22 to photograph the threaded hole on the product without dead angles. The wall body at the through hole 15 is thin, and the wall body at the through hole 15 will not block the shooting and positioning of the camera 22.

[0025] A positioning groove 120 is arranged on the fixture plate 12. The positioning groove 120 is used to place products. In this way, the product is more stable when moving in the positioning groove 120 and will not slide or shift.

[0026] The feeding assembly 1 also includes a slide plate 16, a cylinder 17, a support 18 and a lever 19. The slide plate 16 is slidably arranged on the linear module 11, the cylinder 17, the support 18 and the jig plate 12 are arranged on the slide plate 16, the lever 19 is rotatably arranged on the support 18, and the two ends of the lever 19 are respectively connected to the driving end of the cylinder 17 and the cover plate 13. The cylinder 17 drives the lever 19 to rotate, and the lever 19 is rotatably connected to the driving end of the cylinder 17. The lever 19 drives the cover plate 13 to rotate, thereby realizing the covering or separation of the cover plate 13 and the jig plate 12. An elastic column is arranged between the jig plate 12 and the slide plate 16 to prevent the product on the jig plate 12 from being pressed and damaged.

[0027] The loading assembly 1 also includes a support rod 10 and a positioning column 100. The positioning column 100 is arranged on the support rod 10. The cover plate 13 is provided with a positioning hole 130. The positioning column 100 is sleeved in the positioning hole 130. The positioning hole 130 has a certain length. When the cover plate 13 is reversed, the positioning hole 130 and the positioning column 100 can be separated.

[0028] like Figure 6 As shown, the optical camera assembly 2 includes a top frame 21 and a camera 22. The top frame 21 is arranged on the upper part of the chassis 5, and the camera 22 is arranged on the top frame 21. The camera end of the camera 22 is aimed at the feeding assembly 1. The product on the fixture plate 12 is located within the camera range of the camera 22. There are screw holes on the product for engaging screws. The camera 22 photographs the position of the screw holes on the product. The camera 22 is connected to the PLC controller signal and transmits the data to the electric screwdriver locking module 3 through the PLC controller.

[0029] The optical camera assembly 2 also includes a first vertical rod 23, a second vertical rod 24 and an in-position sensor 25. The first vertical rod 23 and the second vertical rod 24 are respectively arranged at two ends of the top frame 21. The heights of the first vertical rod 23 and the second vertical rod 24 on the top frame 21 are adjustable. The in-position sensor 25 is arranged at the bottom of the first vertical rod 23 and the second vertical rod 24, so the height of the in-position sensor 25 is adjustable. The position of the in-position sensor 25 is lower than the position of the camera 22. The in-position sensor 25 and the camera 22 are staggered. The in-position sensor 25 will not block the camera 22 from shooting. When the optical camera assembly 2 is lowered to the set height, it is just convenient for the camera 22 to shoot the threaded hole positioning on the product. The in-position sensor 25 is connected to the PLC controller signal. The in-position sensor 25 sends a signal to the PLC controller, and the PLC controller turns on the camera 22 to shoot.

[0030] like Figure 7As shown, the electric screwdriver locking module 3 includes a two-axis moving platform 31 and an electric screwdriver 32. Both the two-axis moving platform 31 and the electric screwdriver 32 are signal-connected to the PLC controller. The two-axis moving platform 31 is arranged inside the chassis 5. The position of the electric screwdriver locking module 3 is higher than that of the feeding component 1. The electric screwdriver 32 is arranged on the two-axis moving platform 31. The two-axis moving platform 31 drives the electric screwdriver 32 to move up and down or horizontally. The direction in which the linear module 11 drives the jig plate 12 to move is perpendicular to the direction in which the electric screwdriver 32 is driven to move horizontally.

[0031] The electric screwdriver 32 has a bit 33. The bit 33 is used to adsorb or release screws. The electric screwdriver 32 is used to fix the screws on the product. The position data of the linear module 11 driving the jig plate 12 to move is transmitted to the PLC controller. The PLC controller controls the operation of the electric screwdriver locking module 3, so that the two-axis moving platform 31 drives the electric screwdriver 32 above the screw. The electric screwdriver 32 drives the bit 33 to descend to the set height. The bit 33 adsorbs the qualified screws. The bit 33 resets. Then the two-axis moving platform 31 drives the electric screwdriver 32 above the product. The bit 33 descends to the set height again and releases the screws into the screw holes on the product. The electric screwdriver 32 drives the bit 33 to rotate. The bit 33 drives the screws to rotate until the screws mesh with the screw holes. The electric screwdriver 32 resets. The linear module 11 drives the jig plate 12 to reset.

[0032] As Figure 8 and Figure 9 and Figure 10 shown, the feeding component 4 includes an industrial camera 41, a vibrating bowl 42 and a turntable 43. The industrial camera 41 is signal-connected to the PLC controller. The vibrating bowl 42 is used to store screws. The turntable 43 is rotatably arranged on the chassis 5. A plurality of screw grooves 44 are arranged on the outer periphery of the turntable 43. The nuts of the screws are lapped on the turntable 43. The rod parts of the screws are located in the screw grooves 44. The open ends of the screw grooves 44 pass through the discharge end of the vibrating bowl 42 when rotating. The vibrating bowl 42 vibrates to arrange the screws in an orderly manner, so that the screws enter the screw grooves 44 in an orderly manner. The shooting end of the industrial camera 41 is aligned with the outer periphery of the turntable 43. The rotation path of the open ends of the screw grooves 44 passes through the shooting range of the industrial camera 41. The bit 33 is used to adsorb the screws in the screw grooves 44.

[0033] The turntable 43 pauses after rotating by a set angle. The turntable 43 rotates intermittently. When the opening end of the screw groove 44 is exactly aligned with the shooting end of the industrial camera 41, the turntable 43 stops rotating. The bit 33 adsorbs the screw, and then the bit 33 drives the screw to rotate. The industrial camera 41 detects the color, size, and appearance of the screw through the opening end of the screw groove 44 to determine whether it is a qualified screw. The industrial camera 41 transmits the result information to the PLC controller. For the qualified screws, the PLC controller controls the electric screwdriver 32 to move, so that the bit 33 adsorbs the screw and fixes it on the product. For the unqualified screws, the PLC controller controls the electric screwdriver 32 to move, the bit 33 adsorbs and removes the screw, the air supply to the bit 33 is cut off, and the screw is discarded in the set area.

[0034] The feeding assembly 4 further includes a housing 45 and a recycling box 46. The vibrating bowl 42 is arranged inside the housing 45. The recycling box 46 is arranged within the moving path range of the bit 33. When the industrial camera 41 detects that the screw is unqualified, the industrial camera 41 feeds back the detected information to the electric screwdriver locking module 3 through the PLC controller. The bit 33 adsorbs the unqualified screw and drops the screw into the recycling box 46.

[0035] The housing 45 is provided with a discharge port 450. The vibrating bowl 42 has a discharge track 47. The discharge track 47 passes through the discharge port 450, and the discharge end of the discharge track 47 is aligned with the outer circumference of the turntable 43. The screws in the vibrating bowl 42 come out of the discharge track 47 in an orderly manner. Since the screw groove 44 is arranged on the outer circumference of the turntable 43, the screws coming out of the discharge track 47 directly enter the screw groove 44.

[0036] The feeding assembly 4 further includes a chassis 48 and a motor 49. The center of the chassis 48 has a disk hole 40. The turntable 43 is rotatably arranged in the disk hole 40. The driving end of the motor 49 is connected to the center of the bottom of the turntable 43. When the motor 49 drives the turntable 43 to rotate, the wall body at the disk hole 40 can prevent the screws in the screw groove 44 from falling off.

[0037] The chassis 48 is provided with a detection port 480. The detection port 480 is located on the shooting path of the industrial camera 41. Since the screw groove 44 rotates at a decreasing speed when rotating towards the position of the detection port 480 until the opening end of the screw groove 44 is aligned with the detection port 480, the motor 49 pauses driving the turntable 43 to rotate. During this process, the screws in the screw groove 44 will not fall off. After the shooting and detection by the industrial camera 41 are completed, the bit 33 adsorbs the screw away, and the motor 49 continues to drive the turntable 43 to rotate.

[0038] The feeding assembly 4 further includes a limiting mechanism 6. The limiting mechanism 6 includes a vertical plate 61, a pressing plate 62, a limiting column 63 and a limiting spring 64. The vertical plate 61 is bent and arranged on the housing 45. The limiting column 63 is arranged on the vertical plate 61. The limiting spring 64 is sleeved on the limiting column 63. The pressing plate 62 passes through the limiting column 63, and the limiting spring 64 is connected to the pressing plate 62. The pressing plate 62 covers the discharging track 47. In this way, the screws in the discharging track 47 will not accumulate due to congestion, because the pressing plate 62 blocks the space for the screws to jump upward. According to the screws of different heights, the pressing plate 62 can rise or fall on the limiting column 63, and the height of the pressing plate 62 can be automatically adjusted.

[0039] The limiting mechanism 6 further includes a limiting screw 65. A kidney-shaped hole 66 is provided on the vertical plate 61. The kidney-shaped hole 66 has a certain length. The limiting screw 65 passes through the kidney-shaped hole 66. The height of the limiting screw 65 in the kidney-shaped hole 66 is adjustable. The limiting screw 65 can move up and down in the kidney-shaped hole 66. The pressing plate 62 is bent and arranged, and the pressing plate 62 is connected to the limiting screw 65. If you want to fix the height of the pressing plate 62, use the limiting screw 65 to fix the pressing plate 62 and the vertical plate 61 together.

[0040] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
