Description

Technical Field

[0001] The utility model relates to the technical field of automatic processing, in particular to a sucking and lifting device for a cover plate of a circuit board carrier tray. Background Technique

[0002] With the improvement of circuit complexity and the demand for miniaturization, multi-layer circuit boards have been more and more widely used. In the manufacturing process of multi-layer circuit boards, hot pressing operations are required to form a complete electrical structure among the layers. Circuit boards are generally laminated in multiple layers by a hot press. The circuit boards are arranged and placed on a carrier tray, and then a cover plate is covered on the upper layer for lamination. At present, a fully automatic transfer device is generally used to carry the cover plate after the circuit board lamination is discharged. However, for a small lamination line, the cost of the fully automatic transfer device is too high and the volume is too large. If manually carried, due to the heavy weight of the cover plate, two people need to cooperate, which not only consumes labor but also has low efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sucking and lifting device for a cover plate of a circuit board carrier tray to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A sucking and lifting device for a cover plate of a circuit board carrier tray, including a frame. A number of equally spaced roller shafts are installed on the top of the frame along the length direction. Two horizontal and parallel linear guide rails are fixedly installed on the upper side of the frame. A transfer frame is slidably connected between the two linear guide rails. A rectangular top plate is fixedly installed on the top of the transfer frame. Two groups of vertically slidable and telescopic guide rods are installed on the top plate. The lower ends of the two guide rods in each group are fixedly installed with a suction cup group. A vertically downward cylinder is fixedly installed on the upper part of the top plate. The piston rod of the cylinder penetrates the top plate and drives the suction cup group to lift. It also includes two three-way four-way directional control valves and a vacuum generator. The cylinder and the vacuum generator are respectively communicated with two working ports of the directional control valve. The negative pressure port of the vacuum generator is connected with the suction cup group. The input ends of the two directional control valves are connected in parallel.

[0005] Preferably, the transfer frame is assembled by splicing aluminum profiles, and a plurality of handles are installed on the side of the transfer frame.

[0006] Preferably, six switching valves and two AND gate shuttle valves are installed on the transfer frame. The input ends of the switching valves are respectively connected to the air source. The directional control valve adopts a pneumatic directional control valve. The two input ports of the shuttle valve are respectively the output ports of two switching valves. The output ports of the two shuttle valves are respectively connected to the control ports of the two directional control valves. The control ports on the other side of the two directional control valves are respectively connected to the output ports of another two switching valves.

[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows: The carrier tray coming out of the laminator is conveyed to the frame and supported by the roller shafts. After the cover plate is unlocked from the carrier tray, the manual transfer frame is pushed manually above the carrier tray. After the suction cup group moves down to grab the cover plate and then removes it, the manufacturing cost of this device is low, which is used to assist workers in handling the cover plate and is beneficial to improving efficiency.

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0013] Please refer to Figures 1-3 , the present utility model provides a technical solution: A suction lifting device for a circuit board carrier tray cover plate, including a frame 1. A plurality of roller shafts are installed at equal intervals along the length direction on the top of the frame 1. The carrier tray is supported by the roller shafts on the frame 1. Two horizontal and parallel linear guide rails 2 are fixedly installed on the upper side of the frame 1. A transfer frame 3 is slidably connected between the two linear guide rails 2. The transfer frame 3 is assembled by splicing aluminum profiles. A plurality of handles are installed on the side of the transfer frame 3, and the handles facilitate the human hand to hold and push the transfer frame 3 to move horizontally. A rectangular top plate 5 is fixedly installed on the top of the transfer frame 3. Two groups of vertically slidable and telescopic guide rods 7 are installed on the top plate 5. Four guide sleeves are fixedly installed on the top plate 5. The guide rods 7 penetrate the guide sleeves one by one. The guide sleeves play a role in stabilizing the telescopic movement of the guide rods 7. The lower ends of the two guide rods 7 in each group are fixedly installed with a suction cup group 4. The suction cup group 4 includes a plurality of vacuum suction cups.

[0014] A vertically downward cylinder 6 is fixedly installed on the upper part of the top plate 5. The piston rod of the cylinder 6 penetrates through the top plate 5 and drives the suction cup group 4 to lift. It also includes two three-position four-way directional control valves 10 and a vacuum generator 9. The cylinder 6 and the vacuum generator 9 are respectively connected to two working ports of the directional control valve 10. The negative pressure port of the vacuum generator 9 is connected to the suction cup group 4. The input ends of the two directional control valves 10 are connected in parallel. The telescopic stop action of the cylinder 6 and the suction / blow stop action of the vacuum generator 9 are both controlled by the corresponding directional control valve 10.

[0015] Six switching valves 8 and two AND gate shuttle valves 11 are installed on the transfer frame 3. The input ends of the switching valves 8 are respectively connected to the air source. The directional control valve 10 is a pneumatic directional control valve. The two input ports of the shuttle valve 11 are respectively the output ports of the two switching valves 8. The output ports of the two shuttle valves 11 are respectively connected to the control ports of the two directional control valves 10. The control ports on the other sides of the two directional control valves 10 are respectively connected to the output ports of the other two switching valves 8. The negative pressure suction of the vacuum generator 9 and the contraction and lifting of the cylinder 6 both need to close the two switching valves 8 to start, preventing potential safety hazards caused by the negative pressure interruption or the extension of the cylinder 6 due to accidental touch of the switching valve 8 during the process of sucking and lifting the cover plate, resulting in the fall of the cover plate.

[0016] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
