Technical Field

[0001] The utility model relates to the technical field of automatic assembly, in particular to an automatic iron sheet taking and placing mechanism and a manipulator. Background Art

[0002] When producing the bottom shell of an LED display, since a large LED display is composed of multiple small modules, each module LED light board is supported by a plastic bottom shell, and it is required that there should not be too large a gap when spliced ​​into a large screen, the size of the bottom shell is particularly required to be controlled within plus or minus 0.08mm. If the production time of each bottom shell is inconsistent, the size of the bottom shell will be inconsistent; therefore, it is very important to control the time of producing the bottom shell to be consistent; in the specific production process, nuts and iron sheets must be installed in the mold, and then injection molding is performed. Manual installation is not only inefficient but also time-uncontrollable. Installation with a robot is inefficient and costly. Therefore, a jig for installing nuts and iron sheets is required. The designed jig requires a mechanism for automatically taking and placing iron sheets. The existing technology has the problem of low efficiency when taking and placing iron sheets.

[0023] The present invention is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 — Figure 4As shown, the utility model provides a schematic diagram of an automatic iron sheet picking and placing mechanism and a partial schematic diagram of an iron sheet head, including a picking and placing component 2, the picking and placing component 2 is a hollow cylindrical integrated structure, and the tail is connected to the external negative pressure adsorption component, including an iron sheet head 21, a vent body 22 and a fixed tail 23, the iron sheet head 21 is provided with an iron sheet groove 211 that matches the external iron sheet to be picked and placed and a nesting mouth 212 that forms a negative pressure, a sealing ring 213 is set at the position where the nesting mouth 212 contacts the iron sheet, and the fixed tail 23 is connected to the pneumatic component.

[0025] Specifically, the automatic iron sheet picking and placing mechanism and the external iron sheet to be picked and placed are as follows Figure 4 As shown, in this solution, the iron sheet is taken and placed by the pick-and-place component 2, which is a hollow cylindrical mechanism. The top is the iron sheet head 21, and the middle is the mechanism body, which is named as the vent body 22 in this solution. The gas in the iron sheet head 21 can be passed to the outside, and the iron sheet head 21 can also be ventilated. The bottom is a fixed tail 23 for fixing it in the target position. The fixed tail 23 is connected to the air pressure component. In this solution, the adsorption and release of the iron sheet are completed by adjusting the air pressure inside the pick-and-place component 2. When taking the iron sheet, the gas in the picking and placing component 2 is extracted to make its air pressure lower than the atmospheric pressure. The atmospheric pressure presses the iron sheet on the iron sheet head 21. In order to prevent the picking and placing component 2 from leaking, a sealing ring 213 is provided at the part where the iron sheet is embedded in the iron sheet head 21. The sealing ring 213 is an annular elastic ring. When the atmospheric pressure presses the iron sheet, it will be deformed and the gap between the iron sheet and the iron sheet head 21 will be sealed to achieve a sealing effect, thereby realizing the technical effect of adsorbing the iron sheet by negative pressure and releasing the iron sheet by positive pressure or no pressure.

[0026] In one embodiment, the inner diameter of the iron sheet slot 211 is greater than the first predetermined length of the iron sheet, and the depth of the iron sheet slot 211 is less than or equal to the thickness of the iron sheet. Specifically, in this embodiment, the iron sheet is in the shape of a disk with a small protrusion, and the protrusion is a small cylinder. The diameter of the disk is 0.2mm to 0.3mm smaller than the diameter of the iron sheet, so that the iron sheet can be placed exactly in the iron sheet slot 211 without being difficult to place, nor too loose to cause it to fall. The depth of the iron sheet slot 211 can be slightly less than the thickness of the iron sheet, because each pick-up and placement component 2 only takes one iron sheet at a time; thereby achieving the technical effect of placing the iron sheet exactly and easily as in the iron sheet head 21.

[0027] In another embodiment, an annular groove is defined around the nesting opening 212 to match the sealing ring 213, and the sealing ring 213 is partially embedded in the annular groove. The sealing ring 213 is made of an elastic material. Specifically, after the sealing ring 213 is embedded in the annular groove, a portion protrudes outward. When the iron sheet enters the nesting opening 212, the portion protruding outward is squeezed, thereby achieving a technical effect of sealing between the pick-up and placement component 2 and the iron sheet.

[0028] In another embodiment, an even number of slots with a flat bottom are provided on the outer surface of the ventilation body 22, and the depth of the slots is less than the thickness of the side wall of the pick-and-place component 2. Specifically, a position for a wrench needs to be provided between the ventilation body 22 and the iron sheet head 21, which is used to screw the pick-and-place component 2 into the target position. A facet matching the wrench is provided on the cylindrical outer surface of the ventilation body 22, and the facet is the aforementioned depression. The depth should not cause the outer wall of the pick-and-place component 2 to be too thin, as being too thin will make the pick-and-place component 2 easily damaged, thereby achieving the technical effect of being able to fix the pick-and-place component 2 at the target position with the assistance of a wrench.

[0029] In another embodiment, the outer surface of the fixing tail 23 is provided with a thread. Specifically, the front end component is fixed to the target position by the fixing tail 23. The outer surface of the fixing tail 23 is provided with a spiral shape, and is screwed into the target position like a screw, thereby achieving the technical effect of simply and firmly fixing the pick-and-place component 2 to the target position.

[0030] In another embodiment, the pneumatic component includes an air extraction device and a gas transmission device, and the gas transmission device connects the pick-up and placement component 2 to the air extraction device. Specifically, in this embodiment, the gas transmission device is an air pipe 1, and the air extraction device is an air cylinder. The air pipe 1 is connected to the fixed tail 23. The air cylinder controls the air pressure inside the pick-up and placement component 2, thereby achieving the technical effect of automatically picking and placing the iron sheet.

[0031] A manipulator is provided with the aforementioned automatic iron sheet picking and placing mechanism installed at the bottom thereof. In one embodiment, the manipulator carries the automatic iron sheet picking and placing mechanism to a position where the iron sheet is picked up, thereby adsorbing the iron sheet through negative pressure, and then moves the iron sheet picking and placing mechanism to the installation position to release the iron sheet.

[0032] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0033] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
