Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automatic positioning and unplugging device for laptops. Background Technology

[0002] In the laptop manufacturing and assembly process, some steps require the removal of pre-installed cables such as test cables and temporary connection cables. Traditional operations rely heavily on manual labor, resulting in low efficiency and high labor intensity. Furthermore, manual cable removal is prone to uneven clamping force, leading to cable residue and damage to product interfaces. The high positioning accuracy required between the laptop screen and the main unit also means that significant manual positioning deviations affect the accuracy of cable removal. Additionally, manual closing of the laptop cover after removal can damage the screen if the closing pressure is not properly controlled. The completed fixture also requires manual return, further reducing production continuity. Existing semi-automatic cable removal equipment suffers from limitations such as limited functionality, insufficient positioning accuracy, lack of cable removal detection mechanisms, and difficulties in fixture return. It also struggles to achieve precise connection with the previous workstation's transport line, resulting in insufficient fixture receiving stability and failing to meet the demands of large-scale, high-precision production.

The device includes a machine base 10, a conveying mechanism 20, a translational positioning mechanism 30, a wire-pulling mechanism 40, and a cover-closing roller pressing mechanism 50. The machine base 10 is used for assembling and connecting the conveying mechanism 20, the translational positioning mechanism 30, the wire-pulling mechanism 40, and the cover-closing roller pressing mechanism 50. The conveying mechanism 20 is located on one side of the translational positioning mechanism 30 and is used to move a carrier fixture 60, on which a product 61 to be wire-pulled is mounted, to the input end of the translational positioning mechanism 30. The translational positioning mechanism 30 is located at the output end of the conveying mechanism 20 and is used to move the carrier fixture 60 to the wire-pulling station and complete its positioning. The wire-pulling mechanism 40 is located on one side of the translational positioning mechanism 30 and is used to perform wire-pulling operations on the product 61 to be wire-pulled on the carrier fixture 60. The cover-closing roller pressing mechanism 50 is connected to the wire-pulling mechanism 40 and is used to perform a cover-closing operation on the product 61 after the wire-pulling operation. Specifically, by integrating the machine tool 10, conveying mechanism 20, translation and positioning mechanism 30, wire pulling mechanism 40, and cover closing roller pressing mechanism 50, an integrated operation system is constructed, encompassing fixture conveying, product 61 positioning, wire removal, and automatic cover closing, completely replacing the inefficient operation mode of manual labor and decentralized equipment. The coordinated operation of each mechanism achieves full automation of the laptop wire pulling process, significantly improving production efficiency. Simultaneously, the integrated design reduces equipment space occupation, minimizes time loss during process changeovers, ensures the continuity and stability of the operation process, and effectively adapts to the needs of large-scale production. In this embodiment, the product 61 is a laptop computer.

[0021] like Figure 2 and Figure 3 As shown, the conveying mechanism 20 includes a wide-rail conveying module 21, a narrow-rail conveying module 22, and a lifting and rotating module 23; the wide-rail conveying module 21 is used to receive and convey the carrying fixture 60 to the narrow-rail conveying module 22; the narrow-rail conveying module 22 is located between the wide-rail conveying modules 21 and is used to receive the carrying fixture 60 conveyed by the wide-rail conveying module 21 and transfer it to the translation and positioning mechanism 30; the lifting and rotating module 23 is located between the narrow-rail conveying modules 22 and is used to drive the carrying fixture 60 to achieve lifting and rotating actions; The wide-rail conveying module 21 includes two first conveying rails 211 and a wide-rail drive motor 212; the two first conveying rails 211 are symmetrically installed on the upper surface of the machine base 10; the wide-rail drive motor 212 is used to drive the two first conveying rails 211 to run synchronously. The narrow rail conveying module 22 includes two second conveying rails 221 and a narrow rail drive motor 222; the two second conveying rails 221 are symmetrically installed between the two first conveying rails 211 and fixed to the upper surface of the machine base 10; the narrow rail drive motor 222 is used to drive the two second conveying rails 221 to run synchronously.

[0022] Specifically, the two first conveying tracks 211 of the wide-gauge conveying module 21 are symmetrically arranged, forming a seamless connection with the previous workstation's transport line. It can stably receive the carrying fixture 60 conveyed from the previous workstation, adapting to the transfer needs of fixtures of different widths and specifications, and solving the problems of poor connection between traditional conveying equipment and the previous workstation, and the easy falling of fixtures. The narrow-gauge conveying module 22 accurately receives the fixtures conveyed by the wide-gauge conveying and directionally transfers them to the translation and positioning mechanism 30, realizing the graded and precise conveying of fixtures. The wide-gauge drive motor 212 and the narrow-gauge drive motor 222 drive the corresponding tracks to run synchronously, ensuring a smooth conveying process and avoiding the offset or collision of fixtures and products 61. The lifting and rotating module 23 realizes the automatic correction of the fixture direction, laying the foundation for the precise execution of subsequent wire pulling and cover closing operations. The overall conveying mechanism 20 takes into account both connection stability and transfer accuracy.

Specifically, the positioning pin 238 on the top of the lifting and rotating plate 231 can accurately position the carrying fixture 60, preventing the fixture from shifting during lifting and rotation; the transmission cooperation between the rotary reducer 232 and the hollow rotating platform 234 ensures the smoothness and angular accuracy of the rotation action, and realizes the precise adjustment of the fixture direction; the sliding cooperation between the guide sleeve 2361 and the guide rod 2362 provides guidance for the lifting and lowering of the mounting plate 235, ensuring the verticality and stability of the lifting action and preventing the fixture from tilting; the first lifting cylinder 237 provides a stable lifting driving force, which, together with the precise control of the rotary drive motor 233, realizes the coordinated linkage of lifting and rotation actions, with rapid and reliable action response, and can quickly adapt to the fixtures transferred by the wide rail conveying module 21 to meet the rhythm requirements of automated operation.

[0024] like Figure 2As shown, the lifting and rotating module 23 also includes several proximity sensors 239. These proximity sensors 239 are electrically connected to the first lifting cylinder 237 and the rotary drive motor 233, respectively, to detect the direction of the carrying fixture 60. Based on the detection signal, they trigger the first lifting cylinder 237 and the rotary drive motor 233 to operate, thereby driving the lifting and rotating plate 231 to complete lifting and rotating actions. Specifically, the electrical connection between the proximity sensors 239 and the first lifting cylinder 237 and the rotary drive motor 233 enables closed-loop control of automatic fixture direction detection and action triggering. Fixture direction determination and correction can be completed without manual intervention, significantly improving the automation level of the equipment. Real-time feedback of the detection signal ensures accurate triggering of the lifting and rotating action, avoiding operational malfunctions caused by misjudgment of direction, improving the reliability and accuracy of equipment operation, reducing damage to the product 61 or rework caused by directional deviation, and adapting to the efficient conveying of the wide-rail conveying module 21.

The vertical extension section 682 is used to support the screen of the product 61. The return spring 69 is sleeved on the outside of the horizontal bending section 681 and is used to provide elastic restoring force for the rotation of the screen support rod 68.

[0026] Specifically, the front baffle 63 and the rear stop post 64 on the fixture plate 62 cooperate to form a limiting space for the product 61. The front baffle 63 can flexibly adjust the size of the limiting space through the sliding cooperation of the tension spring 631 and the tension guide slider 633, adapting to the fixing needs of different specifications of notebook products 61, and has strong versatility. The sliding connection between the tension guide rail 632 and the tension guide slider 633 ensures smooth movement of the front baffle 63, and the gripping handle 66 facilitates the pulling operation when unlocking the fixture. The screen support rod 68 of the screen support module 65 is connected to the limiting seat through the horizontal bending section 681.

Both ends of the roller pressing wheel shaft 52 are respectively connected to the roller pressing wheel mounting base 53. The roller pressing wheel mounting base 53 is connected to the lower surface of the mounting horizontal plate 54 through a spring pull rod 56.

Specifically, the closing roller 51 is rotatably connected to the roller shaft 52. During the closing process, it rolls the screen of product 61 to avoid scratches caused by sliding friction. The spring rod 56 and the compression spring 57 provide elastic pressing force for the closing roller 51. The pressure can be automatically adjusted according to the material and structure of the screen of product 61 to ensure a tight closing while avoiding excessive pressure that could cause the screen to break. The sliding cooperation between the roller slider 58 and the roller slide rail 59 provides guidance for the movement of the roller mounting base 53, ensuring the smoothness and linearity of the closing roller action and achieving uniform force on the screen during closing. The closing roller mechanism 50 is integrated with the wire pulling mechanism 40 and is driven synchronously by the four-axis linkage robot 42. No additional drive device is required, which simplifies the equipment structure and achieves seamless connection between wire pulling and closing operations, improving work efficiency.

[0033] like Figure 1 As shown, a return plate conveying module 11 is provided below the machine base 10. The return plate conveying module 11 includes two oppositely arranged return plate conveying tracks 111 and a return plate drive motor 112 that drives the two return plate conveying tracks 111 to run synchronously. The return plate conveying module 11 is used to transport the carrying fixture 60 that has completed the wire pulling operation back to the initial station, realizing the return flow. Specifically, the return plate conveying module 11 is located below the machine base 10 and is connected to the return plate conveying tracks 111 through a corresponding conveying device. With the cooperation of the return plate drive motor 112, the carrying fixture 60 that has completed the wire pulling operation is automatically transported back to the initial station, realizing the cyclic return of the fixture. There is no need for manual handling of the fixture, which greatly reduces the intensity of manual labor and avoids the loss or damage of the fixture during the circulation process. The automatic return of the fixture forms a closed loop of input, operation, and return with the previous station transport line and the wide rail conveying module 21, ensuring the continuous operation capability of the equipment. There is no need to wait for the fixture to be replenished, which further improves the production efficiency and improves the automated operation system.

[0034] The working principle of this invention is as follows: Product 61, along with the carrying fixture 60, flows precisely from the previous workstation's transport line to the wide-rail conveyor module 21 of the machine tool 10. The wide-rail drive motor 212 drives the two first conveyor tracks 211 to run synchronously, smoothly conveying the fixture to the second conveyor track 221 of the narrow-rail conveyor module 22. Subsequently, the fixture is transferred to the lifting and rotating module 23. After the proximity sensor 239 detects and determines the fixture's direction, it triggers the first lifting cylinder 237 to drive the lifting and rotating plate 231 to lift. The rotating drive motor 233, through the rotating reducer 232 and the hollow rotating platform 234, drives the fixture to rotate to the preset direction. Subsequently, the lifting rotating plate 231 descends, and the fixture falls onto the narrow rail conveying module 22 and continues to be transferred to the docking conveying track 311 of the translation positioning mechanism 30. The docking drive motor 312 drives the docking conveying track 311 to move, transferring the fixture onto the translation lifting plate 316. After the second lifting cylinder 317 drives the translation lifting plate 316 to rise, the translation drive cylinder 315 pushes the translation base plate 314 to move the fixture to the wire pulling station. The lead screw stepper motor 76 drives the transmission lead screw 78 to rotate, driving the two sets of L-shaped clamping arms 74 to move synchronously towards each other, and clamping the product with the clamping positioning block 75. The product 61 is centered on the side. Simultaneously, the unlocking motor 82 of the fixture unlocking module 80 drives the unlocking ball screw 83 to rotate, which in turn drives the unlocking pull plate 85 to pull the gripping handle 66 of the fixture, thus separating and unlocking the front baffle 63 from the product 61. The four-axis linkage robot arm 42 carries the wire pulling execution module 43 to the preset wire pulling position. After the vision inspection module 44 identifies and positions the wire, the swinging gripper 433 drives the two wire clamps 434 to clamp the wire to be pulled and complete the pulling. After the pulling is completed, the vision inspection module 44 takes a picture to confirm whether the wire has been completely pulled out. The wire pulling operation is completed sequentially at multiple pulling positions. After the wire pulling is completed, the centering positioning module 70 releases the product 61, and the lever cylinder 92 of the lever module 90 drives the lever sleeve 98 to press and lower the screen support rod 68. The four-axis linkage robot arm 42 drives the closing roller 51 to roll along the screen surface of the product 61, and the compression spring 57 provides elastic pressing force to achieve smooth closing. After the closing is completed, the translation positioning mechanism 30 moves the fixture to the return plate conveying module 11, and the return plate drive motor 112 drives the return plate conveying track 111 to run, transporting the carrying fixture 60 back to the initial station to achieve return flow, completing the entire wire pulling and closing operation process.
