Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, and in particular to a material handling and transfer mechanism. Background Technology

[0002] Currently, when applying film to product surfaces, an XZ moving mechanism and a suction nozzle are generally used to pick up the film from the feeding area and then transfer it to the front surface of the product. The suction nozzle is usually set vertically. When the side of the product also needs to be filmed, a flipping structure is generally used to flip the product so that the side is facing up. However, some electronic products have displays on both the front and the side. Electronic products are not suitable for flipping using a flipping structure to avoid damaging the display during the flipping process. Therefore, it is necessary to develop a material picking and transfer mechanism that can operate on both the front and the side. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 3 As shown.

[0026] Example 1: See Figure 1 , Figure 2 A material handling and transfer mechanism includes an XZ transfer mechanism and an operating head 16. The XZ transfer mechanism includes an X moving mechanism and a Z moving mechanism. The X moving mechanism drives the Z moving mechanism to move laterally. The Z moving mechanism is connected to a lifting plate 10 and drives the lifting plate 10 to move up and down. The lower end of the lifting plate 10 is rotatably connected to a fixed plate 15 and a lateral rotation drive device 11. The lateral rotation drive device 11 drives the fixed plate 15 to rotate. The fixed plate 15 is connected to a forward rotation drive device 12. The forward rotation drive device 12 is connected to the operating head 16 and drives the operating head 16 to rotate.

[0027] Compared to existing technologies, this technical solution incorporates a lateral rotation drive device 11 and a forward rotation drive device 12 between the Z-moving mechanism and the operating head 16. The lateral rotation drive device 11 drives the forward rotation drive device and the rotating head to rotate vertically, while the forward rotation drive device 12 drives the rotating head to rotate horizontally. The forward rotation drive device 12 can adjust the horizontal position of the rotating head, such as from horizontal to vertical; when applying film, since the film's length direction is horizontal, it needs to be adjusted to the vertical direction. The lateral rotation drive device 11 can adjust the rotating head from a vertical to a lateral position for lateral operation. Overall, the operation is convenient and quick.

[0028] See Figure 1 , Figure 2 The lower end of the lifting plate 10 is provided with a rotating recessed hole, and the upper end of the fixed plate 15 is provided with a rotating protrusion 25. The rotating protrusion 25 extends into the rotating recessed hole. The lower end of the lifting plate 10 is connected to the lateral rotation drive device 11, which is a lateral rotation motor. The rotating protrusion 25 is provided with a shaft hole, and one end of the rotating shaft of the lateral rotation motor passes through the shaft hole of the rotating protrusion 25 and is rotatably connected to the lower end of the lifting plate 10.

[0029] To simplify the structure, this technical solution uses a lateral rotary motor to drive the rotating protrusion 25 to rotate within the rotating recess, thereby causing the fixed plate 15 and the operating head 16 to rotate laterally together. The rotation angle is between 0 and 90 degrees.

[0030] For ease of setup, the forward rotation drive device 12 in this embodiment is a forward rotation motor, and the shaft of the forward rotation motor is connected to the operating head 16. Furthermore, an angle sensor 13 is connected to the shaft of the forward motor, and the angle sensor 13 is electrically connected to the forward rotation motor.

[0031] When driving the rotating head to rotate horizontally, this technical solution uses a forward rotating motor. Secondly, considering the need for more precise control of the film application angle, this technical solution sets an angle sensor 13 on the rotating shaft of the forward rotating motor. The angle sensor 13 senses the rotation angle of the rotating shaft and obtains the rotation angle of the operating head 16.

[0032] See Figure 1 , Figure 2 as well as Figure 3 The Z-movement mechanism includes a vertical base plate 1 connected to the X-movement mechanism. An upper synchronous wheel 3 and a lower synchronous wheel 9 are connected to the upper and lower ends of one side of the vertical base plate 1, respectively. A servo motor 2 is connected to one of the upper synchronous wheel 3 and the lower synchronous wheel 9. A synchronous belt 4 is connected between the upper synchronous wheel 3 and the lower synchronous wheel 9. A vertical guide rail 5 and several vertical sliders 6 slidably connected to the vertical guide rail 5 are provided on the other side of the vertical base plate 1. One of the vertical sliders 6 is connected to a vertical connecting block 7. The other vertical sliders 6 are connected to a lifting plate 10. The vertical connecting block 7 is fixedly connected to the lifting plate 10 through a connecting rod 8. A clamping block 32 is connected to the side of the vertical connecting block 7. The clamping block 32 and the vertical connecting block 7 clamp one side of the synchronous belt 4.

[0033] In this application, the vertical movement distance of the lifting plate 10 is relatively large, and the precision requirement is relatively high. Therefore, in this embodiment, a synchronous belt 4 is used to drive the lifting plate 10. In this embodiment, the upper synchronous wheel 3 is connected to a servo motor 2. The servo motor 2 drives the upper synchronous wheel 3 to rotate, and one side of the synchronous belt 4 moves up and down, thereby driving the vertical connecting block 7 and the lifting plate 10 to move up and down. To ensure the straightness of the vertical movement of the lifting plate 10, a vertical guide rail 5 and a vertical slider 6 are provided in this embodiment. The vertical slider 6 is connected to the vertical connecting block 7, and the vertical slider 6 moves up and down along the vertical guide rail 5.

[0034] See Figure 3 The vertical connecting block 7 is connected to a sensing sheet, and the vertical base plate 1 is connected to a plurality of sensors 30 for sensing the sensing sheet. The sensors 30 are vertically distributed and are electrically connected to the servo motor 2.

[0035] When driving the lifting block and the operating head 16 to rise and fall, their heights need to be accurately controlled, such as the material picking height and the material unloading height. Therefore, this technical solution uses multiple sensors 30 at different heights to sense the corresponding heights of the operating head 16. When the operating head 16 reaches the corresponding height, the sensor 30 sends a signal to the servo motor 2, and the servo motor 2 stops. In practical applications, a control system can also be included. The sensors 30 and the servo motor 2 are electrically connected to the control system, which controls the operation of the servo motor 2 based on the signals from the sensors 30 and the control program.

[0036] In this embodiment: the operating head 16 includes a suction nozzle or a clamp. The suction nozzle is used to absorb items; in practical applications, the suction head is connected to the vacuum extraction device via a pipe and a switching valve. The clamp can be a finger cylinder, etc., to hold the items. This is prior art and will not be described in detail.

[0037] See Figure 1 , Figure 3 The X-moving mechanism includes a horizontal plate 21, which is connected to a horizontal linear module. The horizontal moving block 17 of the horizontal linear module is fixedly connected to the vertical base plate 1.

[0038] Preferably, the horizontal linear module includes a horizontal frame 20, which is connected to a horizontal motor 22, a lead screw 23, and a horizontal nut block 24. The horizontal motor 22 drives the lead screw 23 to rotate, and the lead screw 23 drives the horizontal nut block 24 to move laterally. The horizontal nut block 24 is fixedly connected to the vertical base plate 1 through a horizontal moving block 17. The horizontal frame 20 is connected to a horizontal guide rail 19, and a horizontal slider 18 is slidably connected to the horizontal guide rail 19. The horizontal slider 18 is fixedly connected to the horizontal moving block 17.

[0039] The X-moving mechanism adopts a horizontal linear module and drives the vertical plate to move horizontally. The horizontal linear module can be a horizontal cylinder, etc. In this embodiment, a lead screw 23 nut structure is adopted. The horizontal motor 22 drives the lead screw 23 to rotate and drives the horizontal nut block 24 to move. In addition, in order to ensure the stability of the horizontal movement, a horizontal guide rail 19 and a horizontal slider 18 are also provided in this embodiment. When the vertical plate 1 moves horizontally, it moves along the horizontal guide rail 19 under the traction of the horizontal slider 18.

[0040] See Figure 3 It also includes a Y-moving mechanism, which includes a longitudinal frame 28 and a longitudinal linear motor 29. The longitudinal linear motor 29 is fixed to the longitudinal frame 28 and connected to the transverse plate 21. The longitudinal linear motor 29 drives the transverse plate 21 to move longitudinally.

[0041] To enable the operating head 16 to move more widely, a Y-moving mechanism is also provided in this embodiment to drive the operating head 16 to move longitudinally.

[0042] Secondly, the longitudinal frame 28 is an inverted U-shape, with load-bearing plates 26 and reinforcing plates 27 connected to the bottom at both ends. The load-bearing plates increase the contact area with the ground and reduce the pressure per unit area, while the reinforcing plates 27 increase the stability of the longitudinal frame 28.

[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
