[0011] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0012] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0013] In some embodiments, please refer to the accompanying drawings. Figures 1-9 A screw-driving device includes a working base 1, a double-speed chain conveyor 2, a bearing mechanism 3, a pushing mechanism 4, a material clamping and limiting component 5, an XYZ three-axis linear module 6, a screw-driving machine 7, a pneumatic rotary screw feeder 8, a torque tester 9, a material distribution mechanism and a waste collection mechanism. The upper front left side of the work base 1 is set as the screw fastening station; the upper front right side of the work base 1 is set as the quality inspection station. A double-speed chain conveyor 2 is fixedly installed on the front side of the upper end of the working base 1; Multiple tooling plates 21 are placed on the movable end of the double-speed chain conveyor 2; a support mechanism 3 for placing PCB boards is installed on the tooling plates 21; The upper front side of the working base 1 and the inside of the working base 1 are also equipped with a pushing mechanism 4 for separating the tooling plate 21 from the double speed chain conveyor 2 to facilitate the screw-driving operation. A clamping and limiting component 5 is installed on the upper front left side of the work base 1 to cooperate with the pushing mechanism 4 to fix the bearing mechanism 3 in the screw fastening position; An XYZ three-axis linear module 6 is fixedly installed on the upper middle right side of the work base 1; a screwdriver 7 is fixedly installed on the Z-axis movable end of the XYZ three-axis linear module 6. A torque tester 9 for testing the torque of the moving end of the screwdriver 7 is fixedly installed on the upper middle left side of the work base 1. A pneumatic rotary screw feeder 8 for dispensing screws one by one is fixedly installed on the upper left side of the work base 1. The pneumatic rotary screw feeder 8 adopts mature technologies in the industry, such as the pneumatic rotary screw feeder of the brand ZEDA. A material sorting mechanism is installed on the upper right side of the work base 1 to remove products with screw fastening deviations from the production line; The upper left side and inside of the work base 1 are also equipped with a waste collection mechanism for storing misaligned screws that occur during the fastening process; In this invention, the double-speed chain conveyor 2 drives the PCB board that needs to be screwed to move from the left side of the double-speed chain conveyor 2 to the screw fastening station; then the pushing mechanism 4 pushes the tooling plate 21 at the screw fastening station upward. At this time, the tooling plate 21 will drive the carrying mechanism 3 to move upward together until the carrying mechanism 3 contacts the clamping and limiting component 5 and is limited by the clamping and limiting component 5. At this time, the upper end of the carrying mechanism 3 is pressed against the clamping and limiting component 5. Then, the XYZ three-axis linear module 6 first drives the screwdriver 7 to the position of the torque tester 9, and drives the moving end of the screwdriver 7 to contact the test end of the torque tester 9. Then the screwdriver 7 simulates the action of tightening the bolt. At this time, the torque tester 9 will test whether the torque of the screwdriver 7 is within the set range. After the test results are normal, the XYZ three-axis linear module 6 works again to drive the screw driving machine 7 to the outlet position of the pneumatic rotary screw feeder 8. Then, the screw driving machine 7 picks up and fixes the bolt at the outlet position of the pneumatic rotary screw feeder 8. Then, the XYZ three-axis linear module 6 works to drive the screw driving machine 7 to the position of the clamping and limiting component 5. Through the clamping and limiting component 5, the moving end of the screw driving machine 7 is precisely aligned with the part of the product that needs to be screwed. Then, the screw driving machine 7 works to fix the screw to the product. Subsequently, the XYZ three-axis linear module 6 drives the screw fastening machine 7 to move back to the position of the air suction rotary screw feeder 8, so that the screw fastening machine 7 can pick up the next screw and continue to perform screw fastening operation. Then repeat the above operation until all screw holes on the PCB are fastened; Subsequently, the pushing mechanism 4 operates, causing the tooling plate 21 loaded with the completed screw fastening operation to move downwards and re-engage with the moving end of the double-speed chain conveyor 2. Then, the double-speed chain conveyor 2 operates, causing the tooling plate 21 to move to the right. Subsequently, the pushing mechanism 4 operates again to block the tooling plate 21 loaded with the completed screw fastening operation and causes the next tooling plate 21 that has moved to the screw fastening station to move upwards. Then repeat the above operations to drive screws into the products at the screw fastening station; and perform quality inspection on the products that have completed the screw fastening station. With the cooperation of the XYZ three-axis linear module 6, torque tester 9 and double-speed chain conveyor 2, the screw fastening machine 7 can always be in the best working condition, thereby achieving high-efficiency continuous bolt fastening operation. If the screws are misaligned with the PCB board during screw fastening, causing the screws to fail to enter the product, the screw fastening machine 7 will place the misaligned screws into the waste collection mechanism for storage. Meanwhile, the sorting mechanism will separate the corresponding tooling plate 21 at the quality inspection station from the double-speed chain conveyor 2, and the operator will remove it. This achieves automatic separation of qualified and unqualified products, improving production efficiency.

[0014] like Figure 4 and Figure 6 As shown, the supporting mechanism 3 includes a placement plate 32; the placement plate 32 is fixedly installed on the upper end of the tooling plate 21; a contour mounting groove 31 for placing products is opened in the middle of the placement plate 32; a plurality of positioning holes 33 are opened at the upper end of the placement plate 32; the positioning holes 33 are distributed in a rectangular array at the upper end of the placement plate 32. like Figure 6 and Figure 7As shown, the pushing mechanism 4 includes a vertical dual-axis cylinder 41, a buffer stopper 42, a bottom base plate 43, a vertical push cylinder 44, a middle base plate 45, a telescopic guide rod 46, a top base plate 47, a photoelectric sensor 48, a push rod 49, a support horizontal plate 410, and a support rod 411; the support horizontal plate 410 is fixedly installed on the lower right side of the double-speed chain conveyor 2; the vertical dual-axis cylinder 41 is fixedly installed on the upper right side of the support horizontal plate 410; and the buffer stopper 42 is fixedly installed on the upper left side of the support horizontal plate 410. The bottom substrate 43 is fixedly installed inside the lower side of the work base 1; the middle substrate 45 is fixedly installed on the lower left side of the double-speed chain conveyor 2; a light-transmitting groove 451 is opened in the middle of the middle substrate 45; The bottom substrate 43 and the middle substrate 45 are fixedly connected by a support rod 411; the support rod 411 is symmetrically distributed on the front and rear sides of the upper end of the bottom substrate 43. The vertical push cylinder 44 is fixedly installed on the upper end of the bottom base plate 43; the photoelectric sensor 48 is fixedly installed in the middle of the front support rod 411. The output end of the vertical push cylinder 44 is fixedly connected to the top base plate 47; telescopic guide rods 46 are symmetrically fixedly installed on the left and right ends of the bottom base plate 43; the movable end of the telescopic guide rod 46 is fixedly connected to the lower end of the top base plate 47. Multiple push rods 49 are fixedly installed on the upper end of the top base plate 47; like Figure 7 and Figure 8 As shown, the material clamping and limiting assembly 5 includes a limiting plate 51, insert rods 52, a buffer plate 53, a buffer guide rod 54, and a buffer spring 55; the limiting plate 51 is fixedly installed on the upper front left side of the working base 1; a plurality of insert rods 52 that are inserted into the positioning holes 33 are fixedly installed on the inner top of the limiting plate 51; and the insert rods 52 are distributed in a rectangular array on the inner bottom of the limiting plate 51. The upper end of the limiting plate 51 is also symmetrically limited and slidably connected with two buffer guide rods 54 on the front and rear sides; the outer end of the buffer guide rod 54 is wrapped with a buffer spring 55; one end of the buffer spring 55 is fixedly connected to the buffer guide rod 54; the other end of the buffer spring 55 is fixedly connected to the inner bottom of the limiting plate 51. The lower ends of the two buffer guide rods 54 on the same side are fixedly connected to the upper end of the buffer plate 53; The upper end of the limiting plate 51 is provided with multiple positioning guide grooves 56 that match the screwing parts of the product; In this utility model, the double-speed chain conveyor 2 drives the tooling plate 21 loaded with PCB board from the left side of the double-speed chain conveyor 2 to the screw fastening station; and the photoelectric sensor 48 monitors whether the tooling plate 21 has moved to the correct position. Subsequently, the vertical push cylinder 44 works to push the top plate 47 to move upward. At this time, the top plate 47 will pull the extension end of the telescopic guide rod 46 to move vertically upward together. During the movement, the push rod 49 at the upper end of the top plate 47 will contact the lower end of the tooling plate 21, so that the tooling plate 21 is separated from the moving end of the double speed chain conveyor 2. At this time, the placement plate 32 will move upward together with the tooling plate 21. During the movement, the upper end of the placement plate 32 will touch the buffer plate 53, causing the buffer plate 53 to drive the buffer guide rod 54 to move upward. The buffer guide rod 54 will also compress the buffer spring 55, thereby reducing the impact force generated when the placement plate 32 moves upward. Until the positioning hole 33 on the placement plate 32 is inserted into the insertion rod 52; At this time, the product is located below the positioning guide groove 56; then the XYZ three-axis linear module 6 works to first drive the screw driver 7 to move to the position of the torque tester 9, and drive the moving end of the screw driver 7 to contact the test end of the torque tester 9. Then the screw driver 7 works to simulate the action of tightening bolts. At this time, the torque tester 9 will test whether the torque of the screw driver 7 is within the set range. After the test results are normal, the XYZ three-axis linear module 6 works again to drive the screw driving machine 7 to move to the outlet position of the pneumatic rotary screw feeder 8. Then, the screw driving machine 7 picks up and fixes the bolt at the outlet position of the pneumatic rotary screw feeder 8. Then, the XYZ three-axis linear module 6 works to drive the screw driving machine 7 to the position of the clamping limit component 5, and drives the screw driving machine 7 to insert into the positioning guide groove 56 to perform screw fastening operation on the product. After the screw fastening operation is completed, the XYZ three-axis linear module 6 drives the screw fastening machine 7 to reset. At the same time, the vertical push cylinder 44 operates, causing the top base plate 47 to reset downwards. At this time, the push rod 49 will separate from the bottom of the tooling plate 21. Then, the buffer spring 55 returns to its original state, causing the buffer plate 53 to reset. The buffer plate 53 will then press down on the placement plate 32, causing the placement plate 32 to move out of the insertion rod 52. Then, the tooling plate 21 will move back to the top of the push rod 49 and move downwards along with the top base plate 47 until it re-contacts the moving end of the double-speed chain conveyor 2. Then, the double-speed chain conveyor 2 operates, causing the tooling plate 21 to move to the right until it reaches the position of the buffer stopper 42. The buffer stopper 42 operates to block the tooling plate 21 loaded with the product that has completed the screw fastening operation. The vertical double-axis cylinder 41 operates to lift it up for quality inspection. At this time, the vertical push cylinder 44 also drives the tooling plate 21, which has moved to the screw fastening station, to move upward and perform screw fastening operations.

In this invention, if the screw is misaligned with the PCB board during screw fastening, causing the screw to fail to enter the product, the screw fastening machine 7 will put the misaligned screw into the collection tube 14. The screw will then slide along the collection tube 14 into the collection box 15, completing the waste collection operation. Meanwhile, the transverse dual-axis cylinder 10 will push the corresponding tooling plate 21 at the quality inspection station to move out of the double-speed chain conveyor 2. The removed tooling plate 21 will slide along the U-shaped guide frame 11 with the guide roller 12 until the front end of the tooling plate 21 is blocked by the clamping plate 13. Then, the operator can remove the tooling plate 21.
