[0060] See Figure 1 This utility model provides a quick-release flat suction head, including a suction head housing 1, a vacuum generator 2, a rotary slide tube 3, a linear motor 4, a rotary drive assembly 5, and a quick-release contour suction head 6.

[0061] The suction head housing 1 surrounds and forms an upper chamber 101 and a lower chamber 102 located below the upper chamber 101; the vacuum generator 2 is disposed within the upper chamber 101. The upper end of the rotating slide tube 3 is connected to the suction port of the vacuum generator 2 via a hose and / or a rotary joint, and the lower end extends through the lower chamber 102 to the outside of the suction head housing 1. The quick-release contour suction head 6 is detachably and rotatably engaged with the lower end of the rotating slide tube 3.

[0062] The linear motor 4 is located in the lower chamber 102 and is used to drive the rotating slide tube 3 to move up and down; the rotary drive assembly 5 is located in the lower chamber 102 and is used to drive the rotating slide tube 3 to rotate around the vertical axis.

[0063] The quick-release flat suction head provided in this embodiment has the following steps when a workpiece needs to be transferred:

[0064] (1) First, rotate the quick-release contour suction head 6 into the lower end of the rotating slide tube 3, and then start the vacuum generator 2. The bottom of the quick-release contour suction head 6 will generate suction force by rotating the slide tube 3.

[0065] (2) Move the quick-release flat suction head above the workpiece. Then, the linear motor 4 drives the rotating slide tube 3 to move downward, so that the quick-release contour suction head 6 moves downward to fit against the top surface of the workpiece, thereby adsorbing the workpiece.

[0066] (3) The linear motor 4 drives the rotating slide tube 3 to move upward, lifting the workpiece upward;

[0067] (4) The rotary drive assembly 5 drives the rotary slide tube 3 to rotate around the vertical axis so as to rotate the workpiece to the required placement angle.

[0068] In the above process:

[0069] On the one hand, the linear motor 4 is used as the power unit for the up and down movement of the quick-release contouring nozzle 6. Compared with the traditional motor screw assembly, it is smaller in size, thus effectively reducing the overall volume. Furthermore, the nozzle housing 1 is set as an upper and lower cavity structure, which further reduces the lateral volume of the quick-release flat nozzle, so as to work in a narrow space.

[0070] On the other hand, the quick-release contouring suction head 6 and the rotating slide tube 3 are detachably rotated and snapped together. When it is necessary to adapt to workpieces of different specifications and models, only the corresponding quick-release contouring suction head 6 needs to be replaced. Other parts can be reused, which has high compatibility with workpieces of different specifications and models.

[0071] Therefore, the quick-release flat suction head provided in this embodiment can effectively solve the problems of the existing suction head structure being too large to work in confined spaces and having poor compatibility with workpieces of different models and specifications.

[0072] The linear motor 4 is located beside the rotary slide tube 3 and includes a motor stator 401 fixed to the suction head housing 1 and a motor mover 402 driven up and down by the motor stator 401.

[0073] The quick-release flat suction head also includes a rotary bearing 7 and a lifting connecting block 8. The rotary bearing 7 is sleeved on the rotary slide tube 3 and moves up and down synchronously with the rotary slide tube 3; one end of the lifting connecting block 8 is installed on the motor mover 402, and the other end is rotatably connected to the rotary slide tube 3 through the rotary bearing 7.

[0074] Since the rotary bearing 7 moves up and down synchronously with the rotary slide tube 3, when the motor mover 402 moves up and down, it can drive the rotary slide tube 3 to move up and down. When the rotary drive assembly 5 drives the rotary slide tube 3 to rotate, the rotary slide tube 3 will not be restricted by the lifting connecting block 8 and will not be unable to rotate.

[0075] A spring 9 is connected between the motor actuator 402 and the top wall of the upper chamber 101 to drive the motor actuator 402 to slide upward. A spring 10 is connected between the lifting connecting block 8 and the top wall of the upper chamber 101 to drive the lifting connecting block 8 to slide upward.

[0076] The moving spring 9 and the connecting block spring 10 work together to ensure that the rotating slide tube 3 is always in a high position when the linear motor 4 is de-energized, thus preventing the workpiece from falling and being damaged due to abnormal power failure during the transfer process.

[0077] The two tension springs are designed to increase the upward pulling force and ensure that the force on the motor actuator 402 and the lifting connecting block 8 is balanced when they rise, making them less prone to jamming and allowing for smoother upward sliding.

[0078] The rotary drive assembly 5 includes a pulley 501, a belt 502, and a rotary drive mechanism 503.

[0079] The pulley 501 is sleeved on the rotating slide tube 3; wherein, the rotating slide tube 3 is arranged to rotate synchronously with the pulley 501, and the rotating slide tube 3 is arranged to slide up and down relative to the pulley 501; the rotating drive mechanism 503 drives the pulley 501 to rotate the rotating slide tube 3 through the belt 502.

[0080] Optionally, the surface of the rotating slide tube 3 is provided with a longitudinal guide groove 301, and the pulley 501 is provided with a rotation-limiting block that engages in the longitudinal guide groove 301.

[0081] The rotation limiting block can slide up and down along the longitudinal guide groove 301. Therefore, when the linear motor 4 drives the rotary slide tube 3 to move up and down, the pulley 501 will not move up and down with the rotary slide tube 3. However, when the rotary drive mechanism 503 drives the pulley 501 to rotate, the rotation limiting block will drive the rotary slide tube 3 to rotate. This enables the linear motor 4 and the rotary drive assembly 5 to drive each other independently, avoiding interference between them.

[0082] In this embodiment, see Figure 2 The lower end of the rotating slide tube 3 is provided with a rotating locking post 302, and the quick-release contouring suction head 6 is provided with a wing-shaped slot 601 for the rotating locking post 302 to engage. Furthermore, the quick-release contouring suction head 6 is provided with an S-pole magnet 602, and the lower end of the rotating slide tube 3 is provided with an N-pole magnet. When the rotating locking post 302 and the wing-shaped slot 601 are engaged, the S-pole magnet 602 and the N-pole magnet are positioned opposite each other to achieve magnetic positioning.

[0083] When it is necessary to disassemble the quick-release contouring suction head 6, the magnetic attraction between the S pole magnet 602 and the N pole magnet must be overcome first. Push the quick-release contouring suction head 6 upward, then rotate the quick-release contouring suction head 6 around the vertical axis, and finally remove the quick-release contouring suction head 6 downward.

[0084] In summary, the quick-release flat suction head provided in this embodiment has the following advantages:

[0085] ① Compact structure: By adopting a linear motor 4 and designing the suction head housing 1 as an upper and lower cavity structure, the overall volume is effectively reduced, making it convenient to operate in narrow spaces.

[0086] ② High compatibility: The quick-release contouring suction head 6 and the rotating slide tube 3 are detachably rotated and snapped together, so that only the quick-release contouring suction head 6 needs to be replaced to adapt to workpieces of different specifications and models, thus improving compatibility with different workpieces.

[0087] ③ High safety: The mover tension spring 9 and the connecting block tension spring 10 are set to ensure that the rotating slide tube 3 can maintain a high position when the linear motor 4 is de-energized, so as to prevent the workpiece from falling and being damaged.

[0088] ④ Independent drive: The linear motor 4 and the rotary drive assembly 5 are independent of each other, avoiding mutual interference and improving the stability and reliability of the system.

[0089] ⑤ Quick assembly and disassembly: Utilizing the magnetic attraction principle and rotating snap-fit ​​structure, the quick assembly and disassembly of the quick-release contour suction head 6 is achieved, improving work efficiency.
