Description

Technical Field

[0001] This utility model relates to the field of automatic screw driving machine technology, specifically an automatic screw driving machine with visual camera positioning function. Background Technology

[0002] A fully automatic screw-driving machine consists of an automatic screw feeder, an automatic screw tightening machine, and a product fixture. Automatic screw feeders come in two types: air-blowing and suction-type. Air-blowing automatic screw feeders are further divided into inclined barrel type and mechanical lifting type screw feeders. In the automotive parts processing, automatic screw-driving machines play a crucial role. First, they significantly improve production efficiency. Traditional screw tightening methods rely on manual operation, which is not only inefficient but also prone to errors. Automatic screw-driving machines, on the other hand, can achieve high-speed, precise screw tightening operations, enabling the rapid and accurate installation of large quantities of screws, thereby greatly saving production time and improving the efficiency of the entire production line.

[0003] When using a traditional automatic screwdriver, enter the manual operation screen and click to move the product to the locking position (the locking cylinder and robotic arm cylinder must be in the upper position to operate). Remove the drive shaft from the electric / pneumatic screwdriver interface, perform a jog operation, and adjust the screwdriver bit to be 5-10mm away from the product. Loosen the drive shaft retaining clamp and sliding fastening screw, move the screwdriver bit to the corresponding locking hole position, insert the electric screwdriver bit into the screw slot, rotate the electric screwdriver bit to check the alignment, and tighten the screw in this clamp.

[0004] However, existing automatic screw-driving machines require operators to spend more time and energy manually adjusting and monitoring the equipment, increasing the need for human intervention. This not only reduces production efficiency but may also lead to more errors and defective products due to human factors. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an automatic screw-driving machine with a vision camera positioning function. This machine has the advantages of using a vision camera to accurately position screw holes, ensuring screw-driving quality, and improving product yield and production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides an automatic screw-driving machine with a visual camera positioning function, including a worktable, a base on the worktable, a robotic arm mounted on the base, a mounting plate fixed to one end of the robotic arm away from the base, an automatic screw-driving machine mounted on one side of the front end face of the mounting plate, and a visual camera for precise positioning of screw holes detachably fixed to the other side through a first mounting component.

[0008] By adopting the above technical solution and setting up a vision camera, it is possible to accurately locate screw holes, ensure fastening quality, reduce manual intervention, and improve product yield. By setting up the first installation component, it is convenient to disassemble and install the vision camera, and to replace and repair the vision camera.

[0009] Preferably, the first mounting assembly includes a rear support plate that is detachably fixed to the mounting plate by bolts, and an upper support plate with a Z-shaped cross-section is detachably fixed to the upper side of the front end face of the rear support plate by bolts, and the front end face of the upper support plate is detachably fixed to the vision camera by screws.

[0010] By adopting the above technical solution, the vision camera and the mounting plate are connected by an integrated rear support plate and upper support plate, which supports the vision camera and facilitates its disassembly, assembly, and maintenance.

[0011] Preferably, a ring light is provided below the vision camera to illuminate the screw holes of the automotive parts to be screwed, and the ring light is detachably fixed to the rear support plate through a second mounting assembly.

[0012] By adopting the above technical solution, the ring light is supported by the second mounting component, which facilitates the disassembly, assembly, and maintenance of the ring light. By setting the ring light below the vision camera, a continuous and consistent lighting effect is provided, thereby ensuring the accuracy and reliability of the measurement.

[0013] Preferably, the second mounting assembly includes a lower support plate located on the lower side of the front end face of the rear support plate and detachably fixed to the rear support plate by bolts. The lower support plate has a T-shaped cross-section, and a fixing plate is fixedly connected to the lower surface of the lower support plate by screws. The ring light is located below the fixing plate and connected to the fixing plate by a Y-axis moving assembly. A circular hole is passed through the fixing plate located directly below the vision camera, and the inner diameter of the ring light is larger than the diameter of the circular hole.

[0014] By adopting the above technical solution, the rear support plate, lower support plate and fixing plate are fixedly connected by bolts to form an integrated structure. The fixing plate is connected to the ring light through the Y-axis moving component. The center line of the vision camera coincides with the center line of the circular hole. The inner diameter of the ring light is larger than the diameter of the circular hole, which makes it convenient to adjust the position of the ring light without blocking the circular hole and affecting the use of the vision camera.

[0015] Preferably, the Y-axis moving assembly includes two A-shaped lugs fixed to the lower surface of the fixed plate and located beside the circular hole. The two A-shaped lugs are arranged opposite each other, and a screw is rotatably connected between the two A-shaped lugs. The screw is fitted with a slide rail integrated with the fixed plate. A slider is slidably connected to the slide rail. The slider is fitted outside the screw and threadedly connected to the screw. The slider extends out of the slide rail, and a connecting block is fixed to the portion of the slider extending out of the slide rail. A T-shaped groove is formed on the lower surface of the connecting block. A sliding plate is slidably connected in the groove. The connecting block extends out of the lower surface of the sliding plate, and the portion of the sliding plate extending out of the connecting block is fixed to a ring light. An A-motor that drives the screw to rotate is fixed on one of the A-shaped lugs.

[0016] By adopting the above technical solution, the A motor provides power to drive the screw fixed coaxially with the output shaft of the A motor to rotate. The rotation of the screw will drive the slider connected to the screw thread to move in the slide rail. The slide rail guides and limits the movement of the slider. The movement of the slider will drive the connecting block fixed to the slider to move. The movement of the connecting block will drive the slide plate set on the connecting block to move, and in turn drive the ring light fixed to the slide plate to move.

[0017] Preferably, the lower surface of the fixed plate is also provided with an X-axis moving component located on the other side of the circular hole opposite to the slide rail and controlling the movement of the ring light in the X-axis direction.

[0018] By adopting the above technical solution, the X-axis moving component provides power to drive the ring light to move in the X-axis direction, thereby adjusting the position of the light source and improving the lighting effect.

[0019] Preferably, the X-axis moving assembly includes two B-shaped lugs fixed to the lower surface of the fixed plate and located on the other side of the circular hole opposite the slide rail. The two B-shaped lugs are arranged opposite each other, and a long gear is rotatably connected between the two B-shaped lugs. A rack that meshes with the long gear is fixed to the upper surface of the slide plate. The rack extends into the connecting block and is slidably connected to the connecting block. A B-shaped motor that drives the long gear to rotate is fixed on one of the B-shaped lugs.

[0020] By adopting the above technical solution, the B motor provides power to drive the long gear fixed coaxially with the output shaft of the B motor to rotate. The rotation of the long gear will drive the rack meshing with the long gear to move. The movement of the rack will drive the slide plate integrated with the rack to move within the connecting block, thereby driving the ring light fixed to the slide plate to move to adjust the light source.

[0021] The beneficial effects of this utility model are as follows: by setting a vision camera, it is possible to accurately locate screw holes, ensure fastening quality, reduce manual intervention, and improve product yield; by setting a first mounting component, it is convenient to disassemble and assemble the vision camera, and to replace and repair the vision camera; by setting a ring light below the vision camera, it provides a continuous and consistent lighting effect, thereby ensuring the accuracy and reliability of measurement.

By setting the first mounting component 6, the installation and removal of the vision camera 7 can be facilitated, as well as the replacement and maintenance of the vision camera 7. The robotic arm 3 and the automatic screw-driving machine 5 are existing mechanisms, so they will not be described in detail here.

[0031] like Figure 1 and Figure 2 and Figure 3 The first mounting component 6 includes a rear support plate 601 that is detachably fixed to the mounting plate 4 by bolts. An upper support plate 602 with a Z-shaped cross-section is detachably fixed to the upper side of the front end face of the rear support plate 601 by bolts. The front end face of the upper support plate 602 is detachably fixed to the vision camera 7 by screws. The vision camera 7 and the mounting plate 4 are connected by the integrated structure of the rear support plate 601 and the upper support plate 602, which supports the vision camera 7 and facilitates the disassembly, assembly and maintenance of the vision camera 7.

[0032] like Figure 1 and Figure 2 and Figure 3 Below the vision camera 7, there is a ring light 8 that illuminates the screw holes of the automotive parts to be screwed. The ring light 8 is detachably fixed to the rear support plate 601 through the second mounting component 9. The second mounting component 9 supports the ring light 8, which facilitates the disassembly, assembly and maintenance of the ring light 8. By setting the ring light 8 below the vision camera 7, a continuous and consistent lighting effect is provided, thereby ensuring the accuracy and reliability of the measurement.

[0033] like Figure 1 and Figure 2 and Figure 3 The second mounting component 9 includes a lower support plate 901 located on the lower side of the front end face of the rear support plate 601 and detachably fixed to the rear support plate 601 by bolts. The lower support plate 901 has a T-shaped cross section. A fixing plate 902 is fixedly connected to the lower surface of the lower support plate 901 by screws. The ring light 8 is located below the fixing plate 902 and is connected to the fixing plate 902 by the Y-axis moving component 10. A circular hole 903 is passed through the fixing plate 902 and located directly below the vision camera 7. The inner diameter of the ring light 8 is larger than the diameter of the circular hole 903.

[0034] like Figure 1and Figure 2 and Figure 3 The rear support plate 601, the lower support plate 901, and the fixing plate 902 are fixedly connected by bolts to form an integrated structure. The fixing plate 902 is connected to the ring light 8 through the Y-axis moving assembly 10. The center line of the vision camera 7 coincides with the center line of the circular hole 903. The inner diameter of the ring light 8 is larger than the diameter of the circular hole 903, which makes it convenient to adjust the position of the ring light 8 without blocking the circular hole 903 and affecting the use of the vision camera 7.

[0035] like Figure 2 and Figure 3 and Figure 4 The Y-axis moving assembly 10 includes two A-shaped lugs 1001 fixed to the lower surface of the fixed plate 902 and located beside the circular hole 903. The two A-shaped lugs 1001 are arranged opposite to each other, and a screw 1002 is rotatably connected between the two A-shaped lugs 1001. The screw 1002 is fitted with a slide rail 1003, which is integrated with the fixed plate 902. A slider 1004 is slidably connected to the slide rail 1003. The slider 1004 is sleeved on the screw 1002 and threadedly connected to the screw 1002. 04 extends out of the slide 1003, and the part of the slider 1004 extending out of the slide 1003 is fixed with a connecting block 1005. The lower surface of the connecting block 1005 is provided with a T-shaped groove 1006. The slide plate 1007 is slidably connected in the groove 1006. The lower surface of the slide plate 1007 extends out of the connecting block 1005. The part of the slide plate 1007 extending out of the connecting block 1005 is fixed with the ring light 8. One of the A ear seats 1001 is fixed with an A motor that drives the screw 1002 to rotate.

[0036] like Figure 2 and Figure 3 and Figure 4 Power is provided by motor A, which drives the screw 1002, which is coaxially fixed with the output shaft of motor A, to rotate. The rotation of screw 1002 will drive the slider 1004, which is threadedly connected to screw 1002, to move within slide rail 1003. Slide rail 1003 guides and limits the movement of slider 1004. The movement of slider 1004 will drive the connecting block 1005, which is fixed to slider 1004, to move. The movement of connecting block 1005 will drive the slide plate 1007, which is set on connecting block 1005, to move, and in turn drive the ring light 8, which is fixed to slide plate 1007, to move.

[0037] like Figure 2 and Figure 3 and Figure 4The lower surface of the fixing plate 902 is also provided with an X-axis moving component 11 located on the other side of the circular hole 903 opposite to the slide rail 1003 and controlling the movement of the ring light 8 in the X-axis direction. The X-axis moving component 11 provides power to drive the ring light 8 to move in the X-axis direction, so as to adjust the position of the light source and improve the lighting effect.

[0038] like Figure 2 and Figure 3 and Figure 4 The X-axis moving assembly 11 includes two B-ear seats 1101 fixed to the lower surface of the fixed plate 902 and located on the other side of the circular hole 903 opposite to the slide rail 1003. The two B-ear seats 1101 are arranged opposite to each other, and a long gear 1102 is rotatably connected between the two B-ear seats 1101. A rack 1103 that meshes with the long gear 1102 is fixed to the upper surface of the slide plate 1007. The rack 1103 extends into the connecting block 1005 and is slidably connected to the connecting block 1005. A B motor that drives the long gear 1102 to rotate is fixed on one of the B-ear seats 1101.

[0039] like Figure 2 and Figure 3 and Figure 4 Power is provided by motor B, which drives the long gear 1102, which is fixed coaxially with the output shaft of motor B, to rotate. The rotation of the long gear 1102 will drive the rack 1103, which meshes with the long gear 1102, to move. The movement of the rack 1103 will drive the slide plate 1007, which is integrated with the rack 1103, to move within the connecting block 1005, thereby driving the ring light 8, which is fixed to the slide plate 1007, to move to adjust the light source.

[0040] When in use, connect the power supply and turn on the switch. In order to optimize the lighting conditions and ensure that the vision camera 7 can capture clear and accurate images, thereby improving the positioning accuracy, it is necessary to adjust the position of the ring light 8 in the Y-axis direction. Then, turn on the A motor. The A motor provides power to drive the screw 1002, which is fixed coaxially with the output shaft of the A motor, to rotate. The rotation of the screw 1002 will drive the slider 1004, which is threadedly connected to the screw 1002, to move in the slide rail 1003. The slide rail 1003 guides and limits the movement of the slider 1004. The movement of the slider 1004 will drive the connecting block 1005, which is fixed to the slider 1004, to move. The movement of the connecting block 1005 will drive the slide plate 1007, which is set on the connecting block 1005, to move, and then drive the ring light 8, which is fixed to the slide plate 1007, to move.

[0041] The movement of the skateboard 1007 will cause the rack 1103, which is fixed to the skateboard 1007, to move along the center line of the long gear 1102 on the long gear 1102. The long gear 1102 will limit the movement of the skateboard 1007. At this time, the skateboard 1007 will not move in the X-axis direction while moving in the Y-axis direction.

[0042] When the position of the ring light 8 in the X-axis direction needs to be adjusted, the B motor is turned on. The B motor provides power to drive the long gear 1102, which is fixed coaxially with the output shaft of the B motor, to rotate. The rotation of the long gear 1102 will drive the rack 1103, which meshes with the long gear 1102, to move. The movement of the rack 1103 will drive the slide plate 1007, which is integrated with the rack 1103, to move within the connecting block 1005, thereby driving the ring light 8, which is fixed to the slide plate 1007, to move to adjust the light source.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
