[0028] Example

[0029] In order to achieve such Figure 1 The system automatically grips the top cover or finished part (the finished part also uses the top cover for clamping) and adapts to assembly needs. (Refer to...) Figure 2 and Figure 3As shown, this application discloses a cover gripping fixture, including a three-axis drive unit 10, a rotary drive unit 20, an angle adjustment unit 30, and a gripping unit 40. The rotary drive unit 20 is connected to the three-axis drive unit 10 and can move along the XYZ axes under its drive. The angle adjustment unit 30 is connected to the rotary drive unit 20 and can rotate under its drive. The gripping unit 40 is connected to the angle adjustment unit 30 and can adjust its angle under its drive for gripping the cover. (Refer to...) Figure 4 As shown, the upper cover tray D1, the finished tray D2, and the assembly machine D3 for assembling the leaf spring to the upper cover via pins are arranged below the three-axis drive unit 10.

[0030] This application only considers the loading of the top cover or the unloading of the finished product. As for how other parts are loaded, they are handled by other loading mechanisms in actual use, and will not be elaborated on here.

[0031] In practice, the three-axis drive unit 10 drives the gripping unit 40 to move along the XYZ axes in real time and grip a top cover from the top cover tray. When the top cover is placed inside the assembly machine, the rotation drive unit 20 drives the angle adjustment unit 30 to rotate at a set angle. The angle adjustment unit 30 drives the gripping unit 40 to flip to the required angle. In this way, the top cover can be placed in the assembly machine in the set posture to meet the subsequent assembly requirements. The unloading process of the finished product will not be described in detail.

[0032] The three-axis drive unit 10 includes two parallel trusses 11, linear guides 12 respectively mounted above the two trusses 11, an X-axis servo linear module 13, a sliding beam 14 connected to the linear guides 12 and the X-axis servo linear module 13, a Y-axis servo linear module 15 mounted on the sliding beam 14, a Z-axis electric cylinder 16 connected to the Y-axis servo linear module 15, and a base 17 connected to the piston rod of the Z-axis electric cylinder 16. In specific implementation, the X-axis servo linear module 13 and the linear guides 12 cooperate to drive the Y-axis servo linear module 15 on the sliding beam 14. Module 15 moves along the X-axis, and Y-axis servo linear module 15 can drive Z-axis electric cylinder 16 to move along the Y-axis. Z-axis electric cylinder 16 can drive base 17 to move up and down along the Z-axis. In addition, this application also provides an extension plate 18 at the bottom of Z-axis electric cylinder 16. Guide sleeves 181 are installed inside the opposite sides of the extension plate 18. Guide posts 171 are provided on the upper sides of base 17 and pass through the guide sleeves 181. When Z-axis electric cylinder 16 drives base 17 to move up and down, guide posts 171 will extend and retract in guide sleeves 181, effectively ensuring the stability of base 17 in raising and lowering.

[0033] <Rotary drive unit 20>, the rotary drive unit 20 includes a first reduction motor 21 fixed on the base 17 and a T-shaped rotating carrier plate 22 connected to the output shaft of the first reduction motor 21. When the Z-axis electric cylinder 16 drives the base 17 to rise and fall, the rotary drive unit 20 will realize the lifting and lowering movement, and under the drive of the first reduction motor 21, the T-shaped rotating carrier plate 22 will realize the rotation.

[0034] <Angle Adjustment Unit 30> The angle adjustment unit 30 includes a second reduction motor 31 disposed on one side of the vertical portion 511 of the T-shaped rotating carrier plate 22 and having its output shaft pass through the T-shaped rotating carrier plate 22, a small gear 32 disposed on the output shaft of the second reduction motor 31, a rotating shaft (not shown in this application) rotatably disposed on the vertical portion 511 of the T-shaped rotating carrier plate 22 and having a large gear 33 meshing with the small gear 32, and an angle adjustment seat 34 connected to the rotating shaft. When the T-shaped rotating carrier plate 22 rotates, the angle adjustment unit 30 will also rotate. When the angle of the gripping unit 40 is adjusted, the second reduction motor 31 will drive the small gear 32 to cooperate with the large gear 33 so that the angle adjustment seat 34 rotates.

[0035] In one specific implementation, the gripping unit 40 includes a finger cylinder 41 mounted on an angle adjustment seat 34 and two clamps 42 mounted on two output parts of the finger cylinder 41. Under the drive of the rotation drive unit 20 and the angle adjustment unit 30, the gripping unit 40 can rotate at a set angle and adjust as needed. When loading or unloading the top cover or finished product, the finger cylinder 41 can be controlled to drive the two clamps 42 to clamp or lower the top cover or finished product.

[0036] In addition to the above-described structure, this application also includes an angle detection unit 50. The angle detection unit 50 includes a first bending member 51 fixed on the T-shaped rotating carrier plate 22 and having a vertical portion 511, several angle detection sensors 52 arranged on the vertical portion 511 of the first bending member 51, and a second bending member 53 fixed on the angle adjustment seat 34 and having a U-shaped detection portion 531. In specific implementation, the two angle detection sensors 52 can be fixed at any position on the vertical portion 511 of the first bending member 51 as needed. When the U-shaped detection portion 531 of the second bending member 53 is rotated and inserted into the interior of an angle detection sensor 52 and is sensed, it indicates that the angle adjustment unit 30 has driven the gripping unit 40 to rotate to the corresponding angle.

[0037] To facilitate the adjustment of the position of the angle detection sensors, the T-shaped rotating carrier plate 22 of this application is provided with two arc-shaped grooves 512 at the top and bottom. Several angle detection sensors 52 are each screwed into the two arc-shaped grooves 512 to fix them to the T-shaped rotating carrier plate 22. When changing the position of the angle detection sensors 52, the operator can move the angle detection sensors 52 to the corresponding position and screw the two bolts into the two arc-shaped grooves 512.
