Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PCB board manufacturing equipment, in particular to a suction lifting machine used in PCB board production. Background Art
[0002] As we all know, PCB boards provide electrical connections for electronic components. During the production of PCB boards, there are many steps involved, such as the lamination between the substrate and the copper foil to form multiple sheets, and then the separation of the sheets and subsequent finishing. These steps are all completed in the corresponding equipment. If the entire equipment is operated in an automated manner, a material transfer mechanism is required between the equipment. Because PCB boards are special sheets with a smooth surface, they are usually handled by a suction crane.
[0003] Currently, the existing suction lifters used in conventional equipment generally consist of a movable slide, a frame, and suction cups. During operation, the entire machine relies directly on the movable slide to move to the material removal position. Multiple suction cups then act simultaneously on the sheet material to suck it up and then transport it. However, during PCB manufacturing, the sheets are relatively thin in the early stages, and there is vacuum adsorption between the sheets. If the sheets are extracted simultaneously, a greater force is required, making it difficult to lift. Alternatively, when unloading the sheets, if they are simultaneously moved downward and then placed on the processing table, air may be trapped between the sheet material and the processing table (or when pressed, the sheets are stacked together). If the sheet material is placed directly vertically, it is easy to shift due to the air below, resulting in irregular placement and the need for subsequent positioning and calibration, which is not conducive to efficient processing. Utility Model Content
[0004] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a suction lifting machine for use in PCB board production.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A suction lifting machine used in PCB board production includes a base, a frame, a temporary placing table and a storage table. The frame is located above the temporary placing table and the storage table and is installed on the base through slide rails. Under the action of a synchronous belt and a servo motor, the frame can move back and forth along the slide rails. A truss is provided on the frame, and a telescopic cylinder is installed on the truss. A first suction frame is connected to the telescopic head of the telescopic cylinder, and first pneumatic suction cups are evenly arranged on the first suction frame. Cantilevers are respectively provided on both sides of the frame, and at least a pair of mutually symmetrical linear modules are provided on the cantilevers. A second suction frame is provided between the two linear modules, and both ends of the second suction frame are respectively hingedly connected to the sliding seats of the linear modules, and second pneumatic suction cups are evenly arranged on the second suction frame.
[0007] Preferably, a pushing cylinder is provided at the four side edges of the top surface of the temporary placing table, a limiting block is provided on the pushing head of the pushing cylinder, and the top surface of the temporary placing table and the limiting block are arranged to form a slot for temporarily placing the sheet material.
[0008] Preferably, the top surface of the temporary placing table is provided with an avoidance hole along the movable track of the limiting block.
[0009] Preferably, the material storage platform includes a lifting mechanism and a placing platform for stacking and storing sheet materials, and the lifting mechanism is connected to the bottom of the placing platform.
[0010] Preferably, the lifting mechanism is a hydraulic lift.
[0011] Due to the adoption of the above-mentioned scheme, the utility model relies on the movement of the frame on the base to allow the cantilever to extend into the external equipment, so that the first suction rack on the cantilever can pick up and discharge the sheet material, and combined with the hinged connection between the second suction rack and the linear module, relying on the different up and down movement heights between the linear modules at both ends, it is not necessary to suck the material synchronously, so that the suction can first lift the corners, and then gradually lift other parts of the sheet material, so that when discharging, it can be in an inclined direction, gradually discharge the material, and gradually discharge the air between the sheet material and the processing table, making the overall picking and discharging of the sheet material more stable and reliable.

[0020] like Figures 1 to 5As shown, the present embodiment provides a suction lifting machine for PCB board production, comprising a base 1, a frame 2, a temporary placing table 3 and a storage table 4. The frame 2 is located above the temporary placing table 3 and the storage table 4 and is mounted on the base 1 through a slide rail 5. Under the action of a synchronous belt 6 and a servo motor 7, the frame 2 can move back and forth along the slide rail 5. A truss 8 is provided on the frame 2, and a telescopic cylinder 9 is installed on the truss 8. A first suction frame 10 is connected to the telescopic head of the telescopic cylinder 9, and first pneumatic suction cups 11 are evenly arranged on the first suction frame 10. Cantilevers 12 are respectively provided on both sides of the frame 2, and at least a pair of mutually symmetrical linear modules 13 are provided on the cantilevers 12. A second suction frame 14 is provided between the two linear modules 13, and both ends of the second suction frame 14 are respectively hingedly connected to the sliding seats of the linear module 13, and second pneumatic suction cups 15 are evenly arranged on the second suction frame 14.
[0021] This embodiment is mainly used as a transfer of sheet materials between two devices. The aforementioned material picking and unloading are both for inserting into external devices. In specific operation, the servo motor 7 and the synchronous belt 6 drive the frame 2 to move to one side, so that the cantilever 12 on the same side just extends into the top of the discharge port of the external device, and then the linear module 13 of the cantilever 12 can be driven. When the linear module 13 is driven, the second pneumatic suction cup 15 on the second suction frame 14 is pressed against the sheet material, and then the second pneumatic suction cup 15 sucks the sheet material. The linear module 13 on one side remains stationary, and the linear module 13 on the other side moves up a short distance, which can be roughly 1c m, the distance only needs to be sufficient for air to enter the bottom of the sheet, so that the linear module 13 at the other end will move, relying on the second suction frame 14 as a hinged connection structure, so that the second suction frame 14 will present a slope, the slope is about 10 °. It should be noted that the pneumatic suction cup can meet the inclined design because the suction nozzle is a silicone disc, and then it can rise synchronously. When rising, one end can rise to be flush with the other end and then rise synchronously, or it can maintain this inclined angle for synchronous rise.After the ascent is completed, the servo motor 7 drives again to reset the frame 2, and the second suction rack 14 that grabs the sheet material is located above the temporary placing table 3 on the same side. At this time, the linear module 13 can be moved down, and finally the second pneumatic suction cup 15 releases the suction of the sheet material, so that the sheet material is placed on the temporary placing table 3, and then the next sheet material is sucked. When the second suction rack 14 goes to the equipment to suck another sheet material, the first suction rack 10 is just located at the temporary placing table 3, and the telescopic cylinder 9 works to make the first pneumatic suction cup 11 on the first suction rack 10 stick to the sheet material on the temporary placing table 3, and the first pneumatic suction cup 11 works. , it will suck in the sheet material, and then the telescopic cylinder 9 retracts. After the servo motor retracts, the sheet material sucked from the temporary holding table 3 can be placed on the top of the storage table 4, and the telescopic cylinder 9 and the first pneumatic suction cup 11 are combined again to put the sheet material on the storage table 4. The storage table 4 can be used to store multiple sheets. When it is necessary to discharge the sheet material to another device, the second suction rack 14 on the cantilever 12 at the other end works, that is, the linear module 13 at this end drives the second suction rack 14 on the cantilever 12 to move downward when the first suction rack 10 sucks the sheet material, to the top sheet material on the storage table 4, and then sucks the top sheet material , driven by the servo motor 7, the second suction rack 14 on the cantilever 12 at this end is placed above the temporary holding table 3 at the other end, and then the linear module 13 moves down, and then the sheet is placed on the temporary holding table 3. After the temporary holding table 3 corrects the position of the sheet, the linear module 13 at this end is used again to allow the second pneumatic suction cup 15 to suck the sheet. One of the linear modules 13 first rises a short distance. The specific method of taking materials from the equipment is the same, so it will not be described step by step here. When the sheet is sucked, the servo motor 7 moves to this side again, so that the cantilever 12 on this side extends into the feed port of the equipment where the sheet needs to be placed. When discharging the material , first the linear module 13 moves synchronously, and then when the sheet is about to touch the work surface of the equipment, it stops moving down, and only one of the linear modules 13 is allowed to move down, so that the second suction rack 14 here is tilted, and let one end of the sheet touch the work surface first, and then the other linear module 13 continues to descend until the sheet is placed flat on the work surface of the equipment. In this way, the air under the sheet and the work surface can be gradually discharged when the sheet is under the work surface, so as to achieve the effect of stably placing the sheet. According to the above description as a whole, the work of taking and putting out the sheet can be completed, and the sheet transfer between equipment can be perfectly performed.
[0022] Furthermore, after the sheet material is placed on the temporary holding table 3, it needs to be calibrated to facilitate the transfer of the sheet material into the storage table 4 or into the equipment. Therefore, in this embodiment, the four sides of the top surface of the temporary holding table 3 are provided with a pushing cylinder 31, and a limiting block 32 is provided on the pushing head of the pushing cylinder 31. The top surface of the temporary holding table 3 and the limiting block 32 are arranged to form a slot for temporarily holding the sheet material.
[0023] Furthermore, in order to better adapt to the length and width of the sheet material, the top surface of the temporary placing table 3 of this embodiment is provided with an avoidance hole 33 along the movable track of the limit block 32. In this way, even if the sheet material is offset after being placed, the sheet material can be gradually positioned according to the movement of the limit block 32. The design of the avoidance hole 33 can also avoid the formation of vacuum bonding between the sheet material and the top surface of the temporary placing table 3.
[0024] Furthermore, regarding the structure of the material storage platform 4, the material storage platform 4 may specifically include a lifting mechanism 41 and a receiving platform 42 for stacking and storing sheet materials. The lifting mechanism 41 is connected to the bottom of the receiving platform 42 and is a hydraulic lift. This design of the lifting mechanism allows for stacking a large number of sheet materials, and allows the receiving platform 42 to provide the most appropriate height when placing sheet materials in or taking them out of the material storage platform 42.
[0025] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
