In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.
[0032] The following will describe the material transfer device and the automated equipment provided by the present utility model with reference to Figures 1 to 2 the relevant content.
[0033] The automated equipment in this embodiment can be any one of inspection equipment, conveying equipment, and assembly equipment that requires material movement. In this embodiment, the conveying equipment is taken as an example for description. The material transfer device is designed to pick up materials one by one, drive the materials to move to a preset position and then put them down, so as to move the materials one by one. In this embodiment, the materials moved by the material transfer device are taken as thin sheet materials as an example for description.
[0034] The material transfer device includes a material picking mechanism (not shown in the figure) and an adsorption mechanism. The material picking mechanism is connected to the base of the conveying equipment, and the adsorption mechanism is connected to the material picking mechanism. The material transfer mechanism can drive the adsorption mechanism to move to a preset position. Specifically, the material picking mechanism is a module or a manipulator. In this embodiment, the manipulator is taken as an example, and the manipulator is provided with a connecting shaft for connecting accessories.
[0035] The adsorption mechanism includes a housing 1, an air extraction element (not shown in the figure), an adsorbing part 2, and a regulating valve (not shown in the figure). The inside of the housing 1 is hollow. The housing 1 in this embodiment includes a main body 11 and a cover plate 12. The main body 11 is square-shaped and has a cavity inside. The main body 11 is connected to the manipulator. An opening is provided at the bottom of the main body 11. The cover plate 12 is connected to the bottom of the main body 11 and covers the opening to seal the cavity. The cover plate 12 is detachably connected to the main body 11. In this embodiment, the detachable connection method is screw connection, which is convenient for disassembling the housing 1.
[0036] Further, a circular connecting ring 13 is provided at the top of the housing 1, and the axis of the connecting ring 13 is vertically arranged. A notch 131 is axially opened on the connecting ring 13, and the notch 131 communicates with the inner circle and the outer circle of the connecting ring 13, so that the middle of the connecting ring 13 is disconnected. A locking part 132 is connected to the connecting ring 13, and the locking part 132 penetrates through the notch 131. The locking part 132 can adjust the distance at the notch 131. Specifically, the locking part 132 in this embodiment is a bolt, and the axis of the bolt is perpendicular to the axis of the connecting ring 13. The bolt is slidably connected to one side of the notch 131 of the connecting ring 13 close to the bolt head, and the bolt is threadedly connected to one side of the notch 131 of the connecting ring 13 away from the bolt head. A connecting disc 133 is connected to the bottom end of the connecting ring 13, and the connecting disc 133 is detachably connected to the housing 1. In this embodiment, the detachable connection method is screw connection.
[0037] When the connecting ring 13 is connected to the manipulator, the top end of the connecting ring 13 is sleeved on the connecting shaft of the manipulator. Then, the bolt is screwed, so that the head of the bolt abuts against one side of the notch 131 of the connecting ring 13 close to the head of the bolt. Continuing to tighten the bolt can cause the notch 131 to deform, that is, the side of the notch 131 of the connecting ring 13 far from the head of the bolt moves towards the direction close to the head of the bolt, so that the distance between the two sides of the notch 131 becomes smaller, to hold the connecting shaft tightly and realize the positioning of the connecting ring 13. It should be noted that the connecting ring 13 in this embodiment is made of a material that can generate deformation, such as aluminum, iron or plastic, etc. Aluminum is taken as an example in this embodiment.
[0038] Further, the air extraction element is located inside the housing 1 and is connected to the housing 1. The air extraction element in this embodiment is a vacuum pump. The air inlet of the vacuum pump is communicated with the inside of the housing 1, and the air outlet of the vacuum pump is communicated with the outside of the housing 1. In other embodiments, the air extraction element can also be an air extraction pump.
[0039] A trachea 14 is connected to the bottom of the housing 1, that is, the trachea 14 is connected to the cover plate 12. One end of the trachea 14 is communicated with the inside of the housing 1, and the other end of the trachea 14 is connected to the adsorbing member 2 and is communicated with the adsorbing member 2. The adsorbing member 2 in this embodiment is taken as a suction cup. In other alternative embodiments, the adsorbing member 2 can also be a suction nozzle or a suction head, etc. The regulating valve is connected to the housing 1. The regulating valve can isolate or communicate the inside of the housing 1 from the outside of the housing 1, so as to be able to adjust the pressure inside the housing 1, so that the adsorbing member 2 has a first working state capable of adsorbing materials and a second working state of releasing the adsorbed materials.
[0040] Based on the above, when the material transfer device is operating, the housing 1 is driven by the material transfer mechanism to move to the position of the material to be picked up. During this process, the inside of the housing 1 is evacuated by the air extraction element, and the regulating valve is always in the closed state, that is, the inside of the housing 1 is isolated from the outside of the housing 1, so that a negative pressure is formed inside the housing 1. When the adsorbing member 2 is above the material to be picked up, the adsorbing member 2 is in the first working state. Then, the adsorbing member 2 is driven by the material transfer mechanism to abut against the upper surface of the material. At this time, the interface of the trachea 14 communicated with the adsorbing member 2 is the air outlet, and the interface of the adsorbing member 2 abutting against the material is the air inlet. The adsorbing member 2 adsorbs the material through the negative pressure at the air inlet, realizing the non-destructive picking of the material.
[0041] Then, the material suction member 2 adsorbed with materials is driven by the material transfer mechanism until the material suction member 2 is located above the area for placing materials. Then, the regulating valve is switched to the open state, and the inside of the housing 1 is communicated with the outside of the housing 1, that is, the inside of the housing 1 breaks the vacuum, so that the material suction member 2 is switched to the second working state. At this time, the interface of the air pipe 14 communicated with the material suction member 2 is the air inlet, and the interface of the material suction member 2 abutting against the material is the air outlet. A non-negative pressure is generated at the air outlet of the material suction member 2, and the material suction member 2 releases the adsorption of the material, so that the picked-up material is put down. Finally, without connecting an external air source, the picking and moving of materials are realized only by electricity, and the materials are not easily damaged.
[0042] In addition, the adsorption mechanism can be directly installed at the end of the handling actuator. For example, at the end of the manipulator in this embodiment, the adsorption mechanism has the advantages of being small, light, good in adaptability, and conducive to transformation. The adsorption mechanism can also be directly electrically connected to the manipulator and uniformly controlled through the control system of the manipulator.
[0043] In addition, a pressure monitoring module is provided inside the housing 1. The pressure monitoring module is configured to monitor the pressure inside the housing 1 and control the opening degree of the regulating valve. Specifically, the pressure monitoring module includes a detection unit 3 and a control unit (not shown in the figure). The detection unit 3 and the control unit are both connected to the housing 1. In this embodiment, the detection unit 3 is a barometric pressure sensor, the barometric pressure sensor is connected to the outer wall of the housing 1, the air inlet of the barometric pressure sensor is communicated with the inside of the housing 1, and the barometric pressure sensor is arranged inside the cavity body. In this embodiment, the control unit is a controller, the controller is arranged inside the housing 1, and the regulating valve and the barometric pressure sensor are both electrically connected to the controller.
[0044] Based on the above, during the process of the air extraction element extracting air from the inside of the housing 1, the barometric pressure sensor is used to real-time detect the negative pressure inside the housing 1 and transmit the measured result to the controller. When the negative pressure inside the housing 1 is too large, the controller controls the regulating valve to open a certain angle, thereby reducing the negative pressure inside the housing 1 and maintaining the negative pressure inside the housing 1 within a certain range. It can not only adsorb materials, but also prevent the possibility of damage to the housing 1 due to excessive negative pressure inside the housing 1.
[0045] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the embodiments of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
