[0021] See Figures 1-9As shown, the pull-out force measuring device includes a frame 1 and a feeding line 2 and a discharging line 3 mounted on the frame 1. A synchronous belt transfer mechanism 4 spans above the feeding line 2 and the discharging line 3. A Y-axis servo slide 5 is positioned between the feeding line 2 and the discharging line 3. An X-axis servo slide 6 is positioned at the end of the Y-axis servo slide 5. A Z-axis servo slide 7 is mounted on the X-axis servo slide 6. A screwdriver 8 and a pull-out force gauge 9 are mounted on the Z-axis servo slide 7. A testing fixture 10 is mounted on the Y-axis servo slide 5.

[0022] Preferably, the synchronous belt transfer mechanism 4 consists of a synchronous belt 4-1 and a first cylinder 4-2 disposed on the synchronous belt 4-1, and a negative pressure suction cup 4-3 is installed on the first cylinder 4-2.

[0023] Preferably, the test fixture 10 includes a carrier and a gauge mounted on the carrier. The carrier consists of a base plate 10-1, a limiting block 10-2, and a side-push mechanism. The side-push mechanism consists of a second cylinder 10-3 connected to a push block 10-4.

[0024] Preferably, the inspection tool includes a third cylinder 10-5, a guide post 10-6, and a first slider 10-7. A second slider 10-8 is provided on the first slider 10-7. An "I"-shaped structure 10-9 is provided on the upper part of the second slider 10-8. A bolt 10-10 passes through the second slider 10-8 and is movably limited within the second slider 10-8. A spring is provided on the screw of the bolt 10-10. An anti-fall pressure plate 10-11 is provided on the head of the bolt 10-10.

[0025] Preferably, a "∏"-shaped gripper 9-1 is provided at the lower end of the pull-out force gauge 9.

[0026] The working principle of this pull-out force measuring device is as follows: An employee places the bonded laptop casing 100 onto the feeding line 2. The synchronous belt 4-1 of the synchronous belt transfer mechanism 4 drives the connected first cylinder 4-2 to move to the position of the laptop casing 100. The first cylinder 4-2 then activates and, through the connected negative pressure suction cup 4-3, sucks up the laptop casing 100 and moves it onto the base plate 10-1 of the test fixture 10. The limiting block 10-2 and the side-pushing mechanism of the fixture position the laptop casing 100. The side-pushing mechanism, driven by the second cylinder 10-3, uses the connected push block 10-4 to limit the laptop casing 100 from the side. At this time, the third cylinder 10-5 of the fixture activates and presses the connected first slider 10-7 against the laptop casing 100 through the guide post 10-6. The second slider 10-8 on the fixture falls precisely onto the bonding component 20 on the laptop casing 100. 0. A nut 300 is provided on the bonding component 200, and the bolt 10-10 is coaxial with the nut 300. After the notebook housing 100 is positioned, the Y-axis servo slide 5 starts and moves the notebook housing 100 to the working position of the screw machine 8. The screw machine 8 is precisely moved by the X-axis servo slide 6 and the Z-axis servo slide 7 and inserts the screw machine 8 into the head of the bolt 10-10, presses down the spring and rotates to install the screw of the bolt 10-10 into the nut 300. At this time, the Z-axis servo slide 7 moves the screw machine 8 out. Under the precise control of the Y-axis servo slide 5 and the Z-axis servo slide 7, the pull-out force gauge 9 installs the "∏" shaped gripper 9-1 onto the "I" structure 10-9. The Z-axis servo slide 7 moves and drives the pull-out force gauge 9 to lift the second slider 10-8 and the bolt 10-10 to detect the adhesive force between the bonding component 200 and the notebook housing 100. To prevent bolts 10-10 from falling off or being lost, the equipment includes an anti-drop pressure plate 10-11 on the head of bolt 10-10. The equipment uses a precision servo slide for accurate alignment in the XYZ axes and employs an innovatively designed test fixture to simulate a manual assembly line process, performing pull-out force tests on the product after the bonding process. This highly automated and efficient equipment is suitable for large-scale enterprises.
