[0026] The second locking mechanism includes a second U-shaped plate 12. The top of one side of the screwdriver bar limiting block 6 is fixed with the second U-shaped plate 12. The top of the screwdriver bar limiting block 6 and the second U-shaped plate 12 are in contact with the bottom of the lower pressure plate 5. A second guide block 13 is slidably arranged inside the second U-shaped plate 12. The top of the second guide block 13 is fixedly connected to the bottom of the lower pressure plate 5. A second locking rod 14 is fixed at the bottom center of the second guide block 13. A second locking block 15 is threadedly arranged on the outside of the second locking rod 14 below the second U-shaped plate 12. A washer is movably nested on the outside of the second locking rod 14. The washer is located between the second U-shaped plate 12 and the second locking block 15, which can adjust the distance between the screwdriver bar limiting blocks 6, thereby limiting screwdriver bars of different diameters.

[0027] The second guide block 13 is set as a rectangular structure. The outer side of the second guide block 13 is in contact with the inner side of the second U-shaped plate 12. The height of the second guide block 13 is half the height of the second U-shaped plate 12, which ensures that the second U-shaped plate 12 and the screwdriver rod limiting block 6 can only move in a straight line, so that the two adjacent screwdriver rod limiting blocks 6 can always cooperate with each other to limit the screwdriver rod.

[0028] An L-shaped fixing frame 18 is fixed to the outer wall of the truncated cone 1. A cylinder 19 is fixed through the top of the L-shaped fixing frame 18. The lower end of the cylinder 19 is fixedly connected to the center of the top of the lower pressure plate 5. Guide rods 20 are fixed on both sides of the top of the lower pressure plate 5. The guide rods 20 are slidably connected through the top of the L-shaped fixing frame 18. The setting of the guide rods 20 improves the stability of the lower pressure plate 5.

[0029] A collection box 21 is provided below the discharge hole 7. The bottom of the collection box 21 is provided with an inclined surface. The highest point of the inclined surface is located slightly below the discharge hole 7, which reduces the height when the screwdriver contacts the collection box 21, thus protecting the screwdriver. The screwdriver can also slide inside the collection box 21, which also protects the screwdriver.

[0030] A control cabinet is provided next to the assembly device to control the operation of the drive unit 17 and cylinder 19 on the assembly device.

[0031] Working principle: When using this screwdriver automatic assembly device, first insert one end of the screwdriver shaft into the screwdriver handle, then place the screwdriver handle inside the screwdriver handle slot 3, such as... Figure 5 As shown, according to the scale line on the top of the circular plate 2 near the first U-shaped plate 8, move the screwdriver handle limiting block 4 and the first U-shaped plate 8. When the inner sides of the two screwdriver handle limiting blocks 4 are in contact with the two sides of the screwdriver handle, and the position where the end of the first U-shaped plate 8 is aligned with the scale line is the same as the position where the end of the other first U-shaped plate 8 is aligned with the other scale line, it indicates that the screwdriver handle is placed in the center of the screwdriver handle placement slot 3. Then rotate the first locking block 11. Since the first locking block 11 and the first locking rod 10 are threadedly connected, the first locking block 11 presses the washer and the first U-shaped plate 8, completing the fixation of the first U-shaped plate 8 and the screwdriver handle limiting block 4. It is also necessary to ensure that the screwdriver handle between the screwdriver handle limiting blocks 4 can be taken out normally, so that the next screwdriver handle can be placed between the screwdriver handle limiting blocks 4. The two screwdriver handle limiting blocks 4 prevent the screwdriver handle from tilting during the assembly process.

[0032] Next, start cylinder 19 to drive the lower pressure plate 5 and screwdriver rod limiting block 6 to move downward. When the lower end of the lower pressure plate 5 is about to contact the upper end of the screwdriver rod, stop the operation of cylinder 19. Then move screwdriver rod limiting block 6 and second U-shaped plate 12 so that the inner sides of the two screwdriver rod limiting blocks 6 contact the two sides of the screwdriver rod respectively. By rotating the second locking block 15, the positions of the two screwdriver rod limiting blocks 6 and the second U-shaped plate 12 are fixed, and it is necessary to ensure that the screwdriver rod between the screwdriver rod limiting blocks 6 can move normally.

[0033] After the screwdriver handle limiting blocks 4 at the top of each screwdriver handle placement slot 3 are adjusted, the worker stands near the discharge port 7 and away from the lower pressure plate 5, inserts one end of the screwdriver rod into the screwdriver handle, and then places the lower end of the screwdriver handle between the two screwdriver handle limiting blocks 4 and inside the screwdriver handle placement slot 3. Then, the drive device 17 is activated to rotate the rotating shaft 16, the circular plate 2, and the screwdriver handle placement slot 3 by 60 degrees each time, causing the screwdriver handle and screwdriver rod to rotate away from the worker's position and move towards the lower pressure plate 5. When the empty screwdriver handle placement slot 3 moves in front of the worker, the worker places the pre-assembled screwdriver handle and screwdriver rod between the two screwdriver handle limiting blocks 4 and inside the screwdriver handle placement slot 3. When the pre-assembled screwdriver handle and screwdriver rod move directly below the lower pressure plate 5, the cylinder is activated. 19. Cylinder 19 drives the lower pressure plate 5 and the two screwdriver rod limiting blocks 6 to move downwards. The lower pressure plate 5 presses one end of the screwdriver rod into the inside of the screwdriver handle, completing the assembly of the screwdriver. During the assembly process, the two screwdriver rod limiting blocks 6 prevent the screwdriver rod from tilting, and the two screwdriver handle limiting blocks 4 prevent the screwdriver handle from tilting. Activating cylinder 19 causes the lower pressure plate 5 and the two screwdriver rod limiting blocks 6 to move upwards and reset. Activating drive device 17 moves the assembled screwdriver above the discharge hole 7 and into the collection box 21, thus completing the automatic unloading of the screwdriver. The above assembly process only requires placing the pre-assembled screwdriver handle and the screwdriver handle on the screwdriver rod between the two screwdriver handle limiting blocks 4 and inside the screwdriver handle placement slot 3. Other steps are completed by the assembly device, reducing manual intervention and improving the efficiency of screwdriver assembly.
