[0018] like Figure 1-5 As shown, the embodiments of this utility model include:

[0019] A dual X-axis and dual Z-axis PC platform screw-making machine includes a PC platform 1, a Y-axis linear slide rail 2, a synchronous pulley set 3, a servo motor 4, a base frame 5, a T-shaped countersunk groove 6, a belt traction clamp 7, a position sensing plate 8, a through hole 9, a photoelectric switch 10, a processing table 11, a screw-making head 12, and an XZ-axis dual-axis slide table 13. The PC platform 1 is equipped with two Y-axis linear slide rails 2, and a synchronous pulley set 3 is arranged parallel to each Y-axis linear slide rail 2. One end of the synchronous pulley set 3 is connected to the servo motor 4 for transmission. The base frame 5 is mounted on the Y-axis linear slide rail 2. The base frame 5 has a T-shaped groove 6, and a vertically distributed belt traction clamp 7 and a position sensing plate 8 are arranged in the T-shaped groove 6. Through holes 9 are provided on both sides of the T-shaped groove 6. The belt traction clamp 7 is connected to the synchronous pulley group 3 through the through holes 9. Photoelectric switches 10 matching the position sensing plates 8 are provided at both ends of the Y-axis linear slide rail 2. The base frame 5 supports a processing table 11. Two XZ two-axis slide tables 13 are mounted directly above the processing table 11, each with a screw head 12 hanging on it. The screw heads 12 are back to back.

[0020] The axis of symmetry of the T-shaped sink 6 is aligned with the Y-axis linear slide rail 2.

[0021] Furthermore, the belt traction clamp 7 is provided with an X-axis adjustment line hole 14.

[0022] Furthermore, the XZ dual-axis slide 13 is composed of an X-axis slide 15 and a Z-axis slide 16. The X-axis slide 15 is equipped with a double linear rail 17, and a second pulley group 18 is arranged between the double linear rails 17. The second pulley group 18 is connected to the X-axis slide 15 through a second servo 19. A second sensing plate 20 is arranged at the bottom of the X-axis slide 15, and a second photoelectric sensor 21 is matched on the travel path of the second sensing plate 20. The Z-axis slide 16 is connected to a Z-axis lifting cylinder 22.

[0023] Furthermore, a pair of columns are provided on both sides of the PC platform 1, and two vertical plates 23 are mounted on the top of the columns. Several connecting rods 24 are provided between the vertical plates 23. The servo motors 4 are respectively arranged at the left and right ends of the inner side of the vertical plates 23, and the Y-axis linear slide rails 2 are respectively arranged on the outer side of the vertical plates 23.

[0024] Furthermore, the Y-axis linear slide rail 2 and the XZ-axis slide tables 13 are both covered with protective plates.

[0025] This equipment is suitable for fastening various types of screws on PCB boards, smart products and other workpieces, and is especially suitable for scenarios that require double-sided processing or high-speed production.

[0026] Servo motor 4 drives base frame 5 to move along Y-axis slide rail via synchronous pulley group 3. T-shaped sink 6 has built-in belt traction clamp 7 which is fixed to synchronous belt through through hole 9. Position sensor 8 provides real-time feedback on the end-to-end position change of base frame 5 to photoelectric switch 10 to realize closed-loop control.

[0027] The X-axis slide 15 is driven by the second servo motor 4, which drives the second pulley group 18 to move the screw head 12 horizontally; the Z-axis slide 16 is fed vertically by the lifting cylinder to complete the screw fastening action. The two heads are set back to back and can work synchronously or alternately.

[0028] The core components and innovative designs of this product mainly include:

[0029] Dual Y-axis slide alternating operation system:

[0030] The PC platform 1 has two parallel Y-axis linear guides 2 built in, and each guide is equipped with a synchronous pulley set 3, which is driven by a servo motor 4.

[0031] The base frame 5 achieves belt traction transmission through the T-shaped groove 6. The belt traction clamp 7 and position sensing plate 8 are vertically installed in the T-shaped groove 6 to achieve precise positioning and efficient traction, while facilitating assembly and adjustment. Through holes 9 are opened on both sides for the synchronous belt to pass through, ensuring that the belt can be installed on either side, with good compatibility.

[0032] Photoelectric switches 10 are installed at both ends of the Y-axis slide rail. The base frame 5 is accurately positioned by sensing the position sensor 8, which reduces costs while taking into account end-to-end loading and unloading operations.

[0033] Back-to-back double screw head 12 design:

[0034] Two independent XZ two-axis slides 13 are mounted above the processing table 11. Each slide is equipped with a screw head 12. The two heads are set back to back. The processing table 11 can quickly switch back and forth between the two heads, which can greatly improve the screw fastening efficiency, reduce idle stroke, and shorten the processing time.

[0035] The X-axis slide 15 is driven by a double linear guide 17 and a second pulley group 18, and controlled by a second servo motor 4. A second sensor 20 is installed at the bottom to cooperate with a second photoelectric switch 10 to ensure X-axis positioning accuracy. The two machine heads operate independently, improving cost and locking efficiency.

[0036] The Z-axis slide 16 is connected to a lifting cylinder to achieve vertical feeding of the screw head 12.

[0037] Optimized structure of base frame 5 and synchronous belt traction:

[0038] The axis of symmetry of the T-shaped sink 6 is aligned with the Y-axis slide rail, which facilitates installation and adjustment, and also enhances the operational stability of the base frame 5.

[0039] The belt traction clamp 7 has an X-axis adjustment hole 14, which facilitates fine adjustment of the synchronous belt tension, improves compatibility, and can also balance the linear speed of the two lines.

[0040] The servo motor 4 is built into the inside of the vertical plate 23, and the Y-axis slide rail is externally mounted, forming two back-to-back translation channels. The structure is compact and easy to maintain, shortening the stroke of the screw machine and improving efficiency.

[0041] Through the above methods, the dual Y-axis slide, dual X-axis slide 15, and dual Z-axis screw head 12 work together to significantly improve processing efficiency. The synchronous belt pulley set 3 replaces the traditional lead screw, enabling end-to-end directional feeding and unloading of parts, reducing costs by 30% and decreasing operating noise. Optimized designs such as the T-shaped groove 6 and X-axis adjustment hole 14 improve compatibility with belts and ensure the stability of synchronous belt traction. The back-to-back head layout saves space and adapts to the multi-faceted processing needs of complex workpieces.

[0042] In summary, this utility model provides a screw fastening machine with a dual X-axis and dual Z-axis PC platform 1, which achieves a high-efficiency and low-cost screw fastening method. Through the alternating processing of dual Y-axis slides, the back-to-back collaborative operation of dual screw head 12, and the structural optimization design of the synchronous pulley group 3 and the T-shaped groove 6 base frame 5, the problems of low efficiency and high cost of traditional screw fastening machines are solved, and high-speed and stable screw fastening is achieved.
