[0083] The tray installation component 84 includes a bracket 841, a tray frame 842, a front plate 843 and a handle 844. The tray frame 842 includes a carrier plate 8421 and a positioning block 8422. A plurality of positioning blocks 8422 are arranged on the carrier plate 8421 to position the tray. Specifically, a front side positioning block, a first side positioning block and a second side positioning block are arranged on the carrier plate 8421. There are two first side positioning blocks and two second side positioning blocks. The front side positioning blocks, the first side positioning blocks and the second side positioning blocks jointly position the tray to prevent the tray 83 with the unqualified screen body after the punching is completed from being separated. The front plate 843 is connected to the carrier plate 8421, and a handle 844 is arranged on the front plate 843. Specifically, the bottom of the bracket 841 is connected to the moving component 82, the tray frame 842 moves relative to the bracket 841, and the handle 844 is arranged on the outer wall of the front plate 843.

[0084] When a certain number of unqualified screens after punching are placed on the tray 83 of the tray mounting component 84 or the tray 83 is full, the handle 844 is pulled manually, and the tray rack 842 moves relative to the bracket 841. The tray rack 842 will protrude from the outer cover of the laser punching equipment, and the unqualified screens after punching can be taken out together with the tray 83. Subsequently, the tray mounting component 84 is returned to its original position while ensuring the placement of a new tray, so as to prepare for the placement of the unqualified screens after punching next time.

[0085] (8) Feeding mechanism

[0086] like Figure 2 and Figure 3 As shown, the unloading mechanism 6 is used to load the empty pallet, so that the robot can place the qualified screen body after punching on the empty pallet, and unload the full pallet filled with qualified screen bodies after punching. The unloading mechanism 6 includes an empty pallet loading area, a full pallet unloading area, a rack S, a first lifting component 65, a second lifting component 66, a pallet adsorption component 1 67, a pallet adsorption component 2 68, a pallet transfer component 69, a pallet separation component 70 and an adjustment component (adjusting the position of the pallet on the rack S, not described).

[0087] The rack S is a frame structure, which forms an empty pallet work area and a full pallet work area. The first lifting component is set in the empty pallet work area, and the second lifting component is set in the full pallet work area. The empty pallet work area is provided with a plurality of first moving rollers 61, which are used to move a plurality of stacked empty pallets to the first lifting component 65, so that the manipulator can place the qualified screen body after the punching is completed. The pallet filled with qualified screen bodies after the punching is transferred to the second lifting component, and a plurality of full pallets will be stacked on the second lifting component. The full pallet work area is provided with a plurality of second moving rollers 62, which are used to unload the stacked full pallets. A full pallet is a pallet filled with qualified screen bodies after the punching is completed, and an empty pallet is a pallet without any screen body. The lowest working position of the first lifting component can be lower than the first moving roller 61 for the movement of the empty pallet, and the lowest working position of the second lifting component is lower than the second moving roller 62 for the movement of the empty pallet. The lowest working positions of the first lifting component and the second lifting component are both the lowest working heights in their own lifting directions.

[0088] A first mounting frame 63 is formed at the rear of the rack S, and a second mounting frame 64 is formed at the middle of the rack S. The first mounting frame 63 and the second mounting frame 64 are perpendicular to the empty pallet work area and the full pallet work area. The top of the first mounting frame 63 is higher than the top of the second mounting frame 64. The first mounting frame 63 is provided with a first lifting component 65 and a second lifting component 66, respectively. The first lifting component 65 is used to lift the empty pallet to a height suitable for the robot to work so that the robot 5 can absorb the qualified screen body after the punching is completed and place it on the empty pallet. The empty pallet in the empty pallet work area will be converted into a full pallet after being filled with qualified screen bodies after the punching is completed, and the full pallet will be transferred from the empty pallet work area to the full pallet work area. The second lifting component 66 is used to lift to a suitable height to receive the full pallet transferred from the empty pallet work area to the full pallet work area.

[0089] The first mounting frame is provided with a driving component 691 and a first slider, and the driving component 691 drives the first slider to move. The second mounting frame 64 is provided with a first guide rail 692 and a second slider, and the second slider moves on the first guide rail 692. One end of the pallet transfer component 69 is connected to the first slider, and the other end of the pallet transfer component 69 is connected to the second slider. The driving component 691 drives the pallet transfer component 69 to move from the empty pallet work area to the full pallet work area. The pallet transfer component 69 includes a transfer platform 693, and the transfer platform 693 is used to carry a pallet full of qualified screen bodies after punching. Specifically, the driving component 691 drives the pallet transfer component 69 carrying the pallet full of qualified screen bodies after punching to move from the empty pallet work area to the full pallet work area.

[0090] The tray adsorption component 1 67 includes an adsorption bracket 1 671, a lifting component 1 672 and a suction cup 1 673. The adsorption bracket 671 is mounted on the first mounting frame 63, the lifting component 1 672 is mounted on the adsorption bracket 671, and the suction cup 1 673 is mounted on the lifting component 1 672. The lifting movement of the lifting component 1 672 drives the suction cup 1 673 to move up and down. There are multiple suction cups 1 673, and multiple suction cups 1 673 are used to adsorb a tray full of qualified screen bodies after the punching is completed. The structure of the tray adsorption component 2 68 is the same as that of the tray adsorption component 1 67, including an adsorption bracket 2, a lifting component 2 and a suction cup 2. The adsorption bracket is mounted on the second mounting frame 64, the lifting component 2 is mounted on the adsorption bracket, and the suction cup 2 is mounted on the lifting component 2. The lifting movement of the lifting component 2 drives the suction cup 2 to move up and down. There are multiple suction cups 2, and multiple suction cups 2 are used to adsorb a tray full of qualified screen bodies after the punching is completed. The tray adsorption component 1 67 and the tray adsorption component 2 68 adsorb both sides of the tray filled with qualified screen bodies after punching, and place them on the tray transfer component 69.

[0091] The rack S is also provided with a plurality of tray separation components 70, which include a bracket 701, a telescopic part 702, a mounting part 703 and a separator 704. The separator 704 is horizontally arranged on the rack S and connected to the mounting part 703, which is connected to the telescopic part 702, which is mounted on the bracket 701. Under the action of the telescopic part 702, the separator 704 extends to approach the empty tray or retracts to move away from the empty tray. When the first lifting component 67 lifts the stacked empty trays to a suitable height, the separator 704 extends under the action of the telescopic part 702 and is inserted between the top empty tray and the adjacent second top empty tray, thereby fixing the empty trays on the second top and below. Then, the robot 5 absorbs the qualified screen body after the punching is completed and places it on the top empty tray, and the tray adsorption component 1 67 and the tray adsorption component 2 68 adsorb the top tray filled with qualified screen bodies after the punching is completed. The tray separation component 70 can ensure that the manipulator, tray adsorption component 1 and tray adsorption component 2 can only act on the top tray, avoiding adverse effects on the positions of other irrelevant trays, thereby ensuring the accuracy of the tray operation.

[0092] According to the result of the detection mechanism detecting whether the screen body after the punching is qualified, or before the screen body after the punching is placed on the first carrier assembly or before the screen body after the punching is placed on the first carrier assembly, the result of obtaining whether the screen body after the punching is qualified is obtained in advance, and it is determined that there are only two qualified screen bodies after the punching on the second carrier assembly, and the unloading mechanism works, and the first moving rollers 61 in the empty pallet working area move the stacked empty pallets to the first lifting component 65 for the robot to place the qualified screen body after the punching. After the robot places the qualified screen body after the punching, a group of pallet adsorption components 1 67 and pallet adsorption components 2 68 lift and absorb a pallet full of qualified screen bodies after the punching, and the pallet transfer component 69 moves to the bottom of the pallet adsorption components 1 67 and the pallet adsorption components 2 68, and then the pallet adsorption components 1 67 and the pallet adsorption components 2 68 place a pallet full of qualified screen bodies after the punching on the pallet transfer component 69, specifically, on the transfer table 693 where the pallet transfer component 69 is placed. The first lifting component 65 raises the working height of a tray so that the robot 5 can absorb the next tray filled with qualified screens after punching. When the unloading mechanism is working, after the first lifting component 65 lifts the stacked empty trays to a suitable height, the separator 704 extends under the action of the telescopic part 702, and is inserted between the top empty tray and the adjacent second top empty tray, thereby fixing the empty trays on the second top and below. Then the robot 5 absorbs the qualified screens after punching and places them on the top empty tray, and the tray suction component 1 67 and the tray suction component 2 68 suck up the top tray filled with qualified screens after punching.

[0093] The pallet transfer component 69 loaded with pallets full of qualified screens after punching will move from the empty pallet work area to the full pallet work area. Specifically, the pallet transfer component 69 loaded with pallets full of qualified screens after punching will move from under one group of pallet adsorption components 1 67 and pallet adsorption components 2 68 to under another group of pallet adsorption components 1 67 and pallet adsorption components 2. The other group of pallet adsorption components 1 67 and pallet adsorption components 2 adsorb a full pallet on the pallet transfer component 69. The pallet transfer component 69 leaves and places a full pallet on the second lifting component or on a full pallet that has been placed. Each time a full pallet is placed, the second lifting component 66 correspondingly lowers the working height of a pallet. This cycle is repeated until there is no pallet on the first lifting component 65, and a number of full pallets are stacked on the second lifting component 66. A number of second moving rollers 62 move the stacked full pallets out of the unloading mechanism, completing a unloading process.

[0094] Obviously, after a material unloading workflow, the total number of empty pallets placed in the empty pallet placement area before the robot is not working is equal to the total number of full pallets placed in the full pallet placement area before the unloading mechanism is moved out during the material unloading workflow.

[0095] The present invention provides a method for blanking a screen body, using any of the above blanking devices, the method comprising the following steps:

[0096] Step S10: The first carrying assembly moves the punched screen to a side close to the carrying mechanism;

[0097] Specifically, step S10 includes the following steps:

[0098] Step S101: placing the punched screen on a first carrying assembly;

[0099] Step S102: the first carrying assembly moves from one end of the first guide rail to the other end of the first guide rail to approach one side of the carrying mechanism;

Specifically, the carrying mechanism moves to the flip assembly, the third mounting member of the flip assembly is located below the second mounting member of the carrying mechanism, and the lifting part of the carrying mechanism descends to place the punched screen on the third mounting member of the flip assembly.

[0105] Step S303: The flip assembly flips the punched screen 180 degrees, and the flip assembly places the punched screen on the second carrier assembly. Specifically, the carrier mechanism will leave or remain stationary, the first driving unit of the flip assembly rotates 180 degrees, and then the punched screen is flipped 180 degrees, the second carrier assembly moves to the flip assembly, and after the 180-degree flip is completed, the lifting unit of the flip assembly will drop to a height position matching the second carrier assembly, and the punched screen is placed on the second carrier assembly.

[0106] Step S40: The carrying mechanism places the screen body after punching on the first carrying component on the second carrying component;

[0107] Step S50: The second carrying assembly receives the screen placed by the carrying mechanism or the flip assembly, and moves the screen to a working range where it can be sucked by the robot;

[0108] Step S60: performing one or more of steps SU, SK or SN according to the result of whether the screen body is qualified after the punching is completed;

[0109] The step SU includes: a robot arm picks up the screen body from the second carrying assembly and places the screen body on the unloading mechanism, and the unloading mechanism unloads the qualified screen body after the punching is completed.

[0110] The step SK includes: the robot picks up the screen from the second carrier assembly and places the screen on the storage assembly. Preferably, it also includes: a material unloading mechanism unloads the qualified screen after the punching is completed;

[0111] The step SN includes: the robot arm picks up the screen body from the second carrying assembly and places the screen body in one of the storage and discharge assemblies. Preferably, it also includes: unloading the unqualified screen body after the punching is completed.

[0112] When steps S10, S20, S30, S40, S50, and S60 are repeated, multiple punched screens can be unloaded. The flipping and qualified inspection of the punched screens can be realized, qualified screens can be placed together for unloading, and unqualified screens can be placed together for unloading. It can also be applicable to punched screens of different sizes, so that the unloading device and unloading method of the present invention have a wider range of uses and better practical applicability.

[0113] Specifically, the conditions for performing step SU are: based on the result of whether the screen body after punching is qualified according to the detection mechanism; or, before the screen body after punching is placed on the first carrier component or the screen body after punching is placed on the first carrier component, the result of whether the screen body after punching is qualified is obtained in advance to determine that there are only two qualified screen bodies after punching on the second carrier component.

[0114] The step SU specifically comprises the following steps:

[0115] Step SU01: The robot places the qualified screen body after punching on the empty pallet in the empty pallet placement area of ​​the unloading mechanism, and a set of pallet suction components 1 and 2 are lifted and lowered to suck up a pallet full of qualified screen bodies after punching, and then the pallet suction components 1 and 2 place the pallet full of qualified screen bodies after punching on the pallet transfer component;

[0116] Step SU02: a tray transfer component carrying a tray full of qualified screen bodies after punching is moved from under one set of tray adsorption components 1 and tray adsorption components 2 to under another set of tray adsorption components 1 and tray adsorption components 2;

[0117] Step SU03: Another set of pallet suction components 1 and 2 suction a full pallet on the pallet transfer component, and place a full pallet on the second lifting component or on the already placed full pallet:

[0118] Step SU also includes step SU04: repeating steps SU01, SU02, and SU03 until there is no pallet on the first lifting component, a plurality of full pallets are stacked on the second lifting component, and a plurality of second moving rollers move the stacked full pallets out of the unloading mechanism, completing a unloading workflow. For example, when multiple partial steps or all steps in steps S10, S20, S30, S40, S50, and S60 are repeated, step SU also includes step SU04: step SU04.

[0119] Specifically, the conditions for performing step SK are: based on the result of whether the screen body after punching is qualified detected by the detection mechanism, or before the screen body after punching is placed on the first carrier component or before the screen body after punching is placed on the first carrier component, the result of whether the screen body after punching is qualified is obtained in advance, and it is determined that there is only one qualified screen body after punching on the second carrier component.

[0120] The step SK specifically comprises the following steps:

[0121] Step SK01: The robot arm picks up the screen from the second carrying assembly and places the screen that has passed the punching process on a plurality of sixth suction cups of the storage assembly;

[0122] Preferably, step SK01 also includes step SK02: wait for the next time when there is only one qualified screen body after punching, the robot absorbs the qualified screen body after punching on the second carrying component and the qualified screen body after punching on the storage component, and places the above two qualified screen bodies after punching on the unloading mechanism for unloading.

[0123] Specifically, the conditions for performing step SN are: based on the result of whether the screen body after punching is qualified detected by the detection mechanism, or before the screen body after punching is placed on the first carrier component or before the screen body after punching is placed on the first carrier component, the result of whether the screen body after punching is qualified is obtained in advance, and it is determined that there is at least one unqualified screen body after punching on the second carrier component.

[0124] The step SN specifically includes the following steps:

[0125] Step SN01: The robot arm picks up the screen from the second carrying assembly and places the unqualified screen after punching on the tray storing the discharge assembly;

[0126] Preferably, step SN01 also includes step SN02: when the tray is full of unqualified screens after punching, the laser punching equipment stops, and the tray full of unqualified screens after punching is removed for unloading by manpower or external force equipment.

[0127] It should be noted that step SK and step SN are not contradictory. When there is a screen body that is unqualified after punching and a screen body that is qualified after punching on the second carrying assembly, steps SK and SN are performed successively. This is beneficial because it can help the manipulator to clearly perform steps SK and SN. Similarly, the manipulator and the storage assembly, and the manipulator and the storage and discharge assembly in the above unloading device also work successively.

[0128] Specifically, in step S20, the result of whether the screen needs to be flipped after the punching is completed is: the result of whether the screen needs to be flipped after the punching is completed is detected by the detection mechanism; or, before the screen after the punching is placed on the first carrier component or before the screen after the punching is placed on the first carrier component, the result of whether the screen needs to be flipped after the punching is obtained in advance.
