Description

Technical Field

[0001] The invention relates to the technical field of automated manufacturing, in particular to a PCB board and PIN needle crimping device and a use method thereof. Background Art

[0002] PCB, or printed circuit board, is one of the important components of the electronics industry. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use printed circuits to make electrical interconnections between the components. The printed circuit board consists of an insulating base plate, connecting wires, and pads for assembling and welding electronic components. It has the dual functions of a conductive circuit and an insulating base plate. It can replace complex wiring to achieve electrical connections between components in the circuit, which not only simplifies the assembly and welding of electronic products, reduces the wiring workload under traditional methods, and greatly reduces the labor intensity of workers, but also reduces the size of the whole machine, reduces product costs, and improves the quality and reliability of electronic equipment. The printed circuit board has good product consistency. It can adopt standardized design, which is conducive to mechanization and automation in the production process. At the same time, the entire assembled and debugged printed circuit board can be used as an independent spare part, which is convenient for the interchange and maintenance of the whole product. At present, printed circuit boards have been widely used in the production and manufacturing of electronic products.

[0003] The earliest printed circuit boards used were paper-based copper-clad printed circuit boards. Since the emergence of semiconductor transistors in the 1950s, the demand for printed circuit boards has risen sharply. In particular, the rapid development and widespread application of integrated circuits have made the size of electronic equipment smaller and smaller, and the density and difficulty of circuit wiring have become increasingly greater, which requires the continuous updating of printed circuit boards. At present, the varieties of printed circuit boards have developed from single-sided boards to double-sided boards, multi-layer boards and flexible boards; the structure and quality have also developed to ultra-high density, miniaturization and high reliability; new design methods, design supplies and board materials and board processes are constantly emerging. In recent years, various computer-aided design application software for printed circuit boards has been popularized and promoted in the industry. In specialized printed circuit board manufacturers, mechanized and automated production has completely replaced manual operations.

[0004] The existing PCB and shell assembly device is divided into a PCB feeding mechanism and a PCB pressing mechanism. Generally, there are two ways to arrange the process in an automated production line. One way is to divide the PCB feeding and pressing into two process stations. The first station places the PCB in the shell and transfers it to the second station for pressing. In this way, during the transmission process, the PCB is not positioned in the shell and is in a free state. The transmission speed is low and the stability is not high. Another way is to arrange two actuators at the same station, first loading and then pressing. This station needs to perform more actions and takes a long time. In addition, the above two methods require the PCBA and the corresponding shell to have an interlocking guide mechanism. While increasing the manufacturing cost, the PCBA body may bend and the components are at risk of being damaged.

[0005] Therefore, how to provide a PCB board and PIN needle crimping device, based on the existing PCB board processing technology, by improving the actions and methods of loading and pressing processes, improve the production efficiency and yield rate of the product, reduce the complex requirements of the product body design structure, and reduce customer manufacturing costs, is a technical problem that needs to be urgently solved by technical personnel in this field.

[0019] The technical solution of the PCB board and PIN needle crimping device mentioned above, and its use method comprises the following steps:

[0020] a. Initial positioning is achieved by controlling the screwing in and out of the adjusting screws on the press adjustment plate to adjust the horizontal position of the servo press;

[0021] b. The solenoid valve sends a signal to control the air path to be connected, and the PCB carrier transfer pneumatic module is started to transfer the PCB board support plate set in the slideway on its upper surface to the PCB board clamping module picking position, completing the loading process steps;

[0027] The advantages and effects of this application are as follows:

[0028] (1) In the PCB board and PIN needle crimping device disclosed in the present invention, one process station is used to perform the two process steps of loading and pressing. Compared with the traditional process of dividing PCB loading and pressing into two process stations, the step of transferring the PCB board between the two process stations is omitted, thereby greatly improving the production efficiency.

[0029] (2) In the PCB board and PIN needle crimping device disclosed in the present invention, a press adjustment plate is used in conjunction with equal height screws, and a quick-change disk connecting plate is used in conjunction with secondary positioning pins to adjust the relative position of the PCB board and the shell, so that their vertical symmetry axes coincide with each other. Compared with the traditional process, the PCB board and the corresponding shell have an interlocking guide mechanism, which reduces the manufacturing cost while avoiding the risk of the PCB board body being bent and damaged by the interlocking guide mechanism, thereby greatly improving the yield rate.

[0030] (3) In the PCB board and PIN needle crimping device disclosed in the present invention, a clamping claw is used to pass through the positioning hole set on the PCB board to directly clamp the PCB board. When approaching the lower shell, the clamping claw is released, and the device continues to descend to complete the pressing process steps.

[0076] Step 6: The product presence sensor 14 sends a signal again to control the PCB carrier transfer pneumatic module 16 to run in the opposite direction, driving the PCB board support plate 17 set in the slideway on its upper surface to return to the initial position;

[0077] Step 7: The servo press 5 is started, and the PCB board clamping module connected to the servo press 5 moves downward, and the secondary positioning is achieved through the PCB board secondary positioning pin 15 and the positioning pin hole set on the tray 2, the purpose of which is to make the PCB board clamping module and the tray 2 set below it further coincide with each other in the vertical direction. When the PCB board approaches the shell, the solenoid valve 19 sends a signal to control the air circuit to disconnect, the clamping cylinder 11 is reset, the clamping claw 12 is released, and the PCB board contacts the shell;

[0078] Step 8: The device continues to descend, and the PIN passes through the hole on the PCB that is slightly smaller than the diameter of the PIN, completing the press-fit process step. The tray moves downward and is transferred to the area of ​​the PIN height detection device via a conveyor belt.
