Description

Technical Field

[0001] This invention relates to the field of non-standard equipment for mobile phone assembly, specifically to a high-speed dual-axis, dual-rail online screw machine. Background Technology

[0002] Mobile phones have become an indispensable part of people's lives, and phone cases are an important component of mobile phones. In the industrial production process, the majority of phone cases require tightening screws during manufacturing. Currently, production lines employ two methods: one is manual screw tightening and loosening by workers. The drawback of this method is that manual removal is laborious, significantly increasing workload and reducing production efficiency. Therefore, existing technology has shortcomings and needs improvement.

[0003] Another approach involves using a three-axis automatic screw fastening machine. Currently, these machines primarily utilize an XYZ three-axis positioning system and a screw tightening system to automatically pick up screws and fasten them into the screw holes, achieving accurate and rapid tightening, significantly improving both production efficiency and product quality. However, existing three-axis automatic screw fastening machines operate on a single line, lacking independent feeding and fixing mechanisms. This prevents the allocation of idle production lines for assembly based on the production speed of two separate lines, greatly reducing the processing efficiency of the automatic screw fastening machine. Furthermore, manual inspection is still required after assembly; products cannot be directly transferred and classified according to quality after processing. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by proposing a high-speed, dual-axis, dual-rail online screw-making machine. The specific technical solution is as follows:

[0009] Support frames are respectively provided between the first conveying section and the second conveying section, and between the first conveying section and the third conveying section;

[0010] A transfer part is slidably installed on the support frame near the third or first conveying part, and an assembly mechanism is slidably installed on the support frame near the first conveying part.

[0011] Both the transfer unit and the assembly mechanism slide between the two assembly lines;

[0012] The transfer section near the inlet of the first conveying section slides between the two assembly lines according to the working conditions, transferring the workpiece of the second conveying section to the first conveying section of the corresponding assembly line;

[0013] The assembly mechanism assembles the workpiece on the first conveying section using screws.

[0014] After assembly, the transfer section near the outlet of the first conveying section transfers the workpiece on the first conveying section to the third conveying section.

[0029] The suction device and the tightening device are fixed on the adjustment part of the height adjustment device.

[0030] Furthermore:

[0031] The transfer section includes a guide rail, a drive motor, a slide, and a transfer device;

[0032] The axial direction of the guide rail is consistent with the arrangement direction of the two assembly lines;

[0033] The slide block is slidably mounted on the guide rail, the drive motor drives the slide block to slide along the guide rail, and the transfer device is mounted on the slide block;

A conveyor bracket slides on a slide rail, carrying the phone housing to the assembly mechanism, where the assembly mechanism places and tightens the screws on the phone housing mounted on the lifting unit. This reduces the labor intensity of workers during assembly, minimizes manual labor input, and improves work efficiency. After assembly, the first conveyor unit transports the phone housing to a transfer unit. The transfer unit uses detection sensors to detect the phone housing, automatically screening it as qualified or unqualified. Qualified housing is sent to a second conveyor unit, and unqualified housing is sent to another second conveyor unit. Attached Figure Description

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] The overall structure diagram of the high-speed dual-axis dual-rail online screw machine is as follows: Figure 1 and Figure 2 As shown:

[0067] A high-speed dual-axis dual-rail online screw machine includes a base 1, an assembly line, a first support frame 2, and a second support frame 3;

[0068] Two assembly lines are arranged side by side on the base 1.

[0069] In this embodiment, for ease of explanation, the two assembly lines are designated as the first assembly line and the second assembly line.

[0070] The first assembly line includes a first conveying section 4, a second conveying section and a third conveying section. The second conveying section is a feeding conveying section 5, and the third conveying section is a discharging conveying section 6. The first conveying section 4 is located between the feeding conveying section 5 and the discharging conveying section 6.

[0071] The feeding conveyor 5 and the discharging conveyor 6 have the same structural components. The only difference is that the feeding and discharging directions are different. Since the feeding conveyor 5 and the discharging conveyor 6 have the same structure, the feeding direction and the discharging direction can be determined according to specific needs in practice.

[0072] The difference between the second assembly line and the first assembly line is that the second conveying section and the third conveying section of the second assembly line are both defective mobile phone case transport sections 7.

[0073] Although the second assembly line uses two conveyor units for defective phone cases, in actual use, only one corresponding to the discharge conveyor unit 6 of the first assembly line is used.

[0074] The purpose of using two conveyor sections for defective phone cases is that, since the only difference between the first assembly line and the first assembly line is the direction of feeding and discharging, after determining the feeding conveyor section 5 and the discharging conveyor section 6 of the first assembly line, the discharging conveyor section 6 of the first assembly line is the conveyor section for qualified phone cases, and the discharging conveyor section 6 of the second assembly line corresponding to the first assembly line is the conveyor section 7 for defective phone cases.

[0075] The specific structure of the first conveying unit 4 is as follows: Figure 9 and Figure 10 As shown:

[0076] The first conveying unit 4 includes a slide rail 4-1, a slide plate 4-2, a conveying bracket 4-3, and a lifting unit 4-4;

[0077] The slide plate 4-2 is slidably mounted on the slide rail 4-1, and the conveying bracket 4-3 is mounted on the slide plate 4-2 and moves with the slide plate 4-2. Limiting parts 4-5 are respectively provided at both ends of the slide rail 4-1.

[0078] Two sets of conveyor belts 4-6 are arranged opposite each other inside the conveyor support 4-3, and the lifting part 4-4 is arranged at the bottom of the conveyor support 4-3;

[0079] A lifting part 4-4 is provided on the slide plate 4-2, and the upper surface of the lifting part 4-4 is a workpiece placement plane. A limiting fixture 4-7 is provided on the top of the conveying bracket 4-3.

[0080] Meanwhile, two sets of limiting mechanisms 4-8 are provided on the slide plate 4-2, and the lifting part 4-4 is located between the two sets of limiting mechanisms 4-8. The two sets of limiting mechanisms 4-8 limit the workpiece placed on the lifting part 4-4.

[0081] The limiting mechanism 4-8 includes a base 4-81, a horizontal pushing cylinder 4-82, a vertical pushing cylinder 4-83, and a limiting block 4-84. The horizontal pushing cylinder 4-82 is placed on the base 4-81, the vertical pushing cylinder 4-83 is placed at the telescopic end of the horizontal pushing cylinder 4-82, and the limiting block 4-84 is fixed to the telescopic end of the vertical pushing cylinder 4-83.

[0082] Support frames are respectively provided between the first conveying section 4 and the feeding conveying section 5, and between the first conveying section 4 and the discharging conveying section 6. For ease of description, the support frame between the first conveying section 4 and the feeding conveying section 5 is named the first support frame 2, and the support frame between the first conveying section 4 and the discharging conveying section 6 is named the second support frame 3. The first support frame 2 and the second support frame 3 are structurally identical.

[0083] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the first support frame 2 and its components are described here:

[0084] A transfer part 8 is slidably installed on the side of the first support frame 2 near the feeding conveying part 5, and an assembly mechanism 9 is slidably installed on the side of the first support frame 2 near the first conveying part 4.

[0085] Both the transfer unit 8 and the assembly mechanism 9 slide between the two assembly lines;

[0086] The transfer part 8 on the first support frame 2 near the entrance of the first conveying part 4 slides between the two assembly lines according to the working conditions, transferring the mobile phone case of the feeding conveying part 5 to the first conveying part 4 of the corresponding assembly line.

[0087] like Figure 6 As shown, the specific structure of the transfer unit 8 is as follows:

[0088] The transfer section 8 includes a guide rail 8-1, a drive motor 8-2, a slide 8-3, and a transfer device 8-4;

[0089] The axial direction of the guide rail 8-1 is consistent with the arrangement direction of the two assembly lines;

[0090] The slide block 8-3 is slidably mounted on the guide rail 8-1, the drive motor 8-2 drives the slide block 8-3 to slide along the guide rail 8-1, and the transfer device 8-4 is mounted on the slide plate 4-2;

[0091] The transfer device 8-4 includes two connecting plates 8-41, which are arranged opposite to each other on the slide 8-3. A conveyor belt 8-42 is provided on the inner wall of each of the two connecting plates 8-41.

[0092] A detection device 8-43 is provided on the slide 8-3. The mobile phone case is conveyed on the conveyor belt 8-42. When it passes through the detection device 8-43, the detection device 8-43 detects the assembled mobile phone case. According to the detection result of the detection device 8-43, if the detection is qualified, the transfer unit 8 docks with the discharge transmission unit of the first assembly line and is discharged by the discharge transmission unit of the first assembly line.

[0093] If the inspection fails, the transfer unit 8 connects with the discharge transmission unit of the second assembly line and is then discharged by the discharge transmission unit of the second assembly line.

[0094] The assembly mechanism 9 assembles the workpiece on the first conveying section 4 with screws.

[0095] After assembly, the transfer section 8, located near the outlet of the first conveying section 4, transfers the workpiece on the first conveying section 4 to the discharge conveying section 6.

[0096] The assembly mechanism 9 assembles the workpiece on the first conveying section 4 with screws.

[0097] After assembly, the transfer part 8 on the second support frame 3 transfers the workpiece on the first conveying part 4 to the second conveying part.

[0098] The second conveying section uses a belt conveyor.

[0099] The structure of assembly mechanism 9 is as follows Figure 8 As shown, the assembly mechanism 9 includes a sliding plate 9-1, a height adjustment device 9-2, an image recognition device 9-3, a suction device 9-4, and a tightening device 9-5;

[0100] The sliding plate 9-1 is slidably mounted on the support frame near the first conveying part 4;

[0101] The fixing part of the height adjustment device 9-2 and the image recognition device 9-3 are fixed on the sliding plate 9-1;

[0102] The suction device 9-4 and the tightening device 9-5 are fixed on the adjusting part of the height adjusting device 9-2. A pressure detection device 9-68-43 is provided on the tightening device 9-5.

[0103] The working principle of this invention is as follows: First, the phone case is fed from the feeding section of the first assembly line, which uses a conveyor belt structure 8-42. The processing module judges the assembly status of the two production lines and notifies the transfer section of the first support frame 2 to transport the phone case from the feeding conveyor 5 to the idle first conveyor section 4 of the assembly mechanism 9. The first conveyor section 4 transports the phone case to the assembly mechanism 9. After the assembly mechanism 9 completes the assembly, the processing module notifies the transfer section of the second support frame 3 to transfer the phone case. When the phone case enters the transfer section of the second support frame 3, it is detected by the photoelectric detection device 8-43. According to the detection result of the photoelectric detection device 8-43, if the detection is qualified, the transfer section 8 connects with the discharge conveyor of the first assembly line and is discharged by the discharge conveyor of the first assembly line. If the detection is unqualified, the transfer section 8 connects with the discharge conveyor of the second assembly line and is discharged by the defective phone case transfer section 7 of the second assembly line.

[0104] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0105] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
