Description

Technical Field

[0001] The utility model relates to the technical field of circuit board disassembly, in particular to the field of PIN de-interlacing machines. Background Art

[0002] Multilayer printed circuit boards (PCBs) are constructed by hot-pressing layers of copper-clad laminate together. Pins are used to precisely position the layers during lamination. After lamination, the pins inserted into the positioning holes need to be removed. This process is called pin removal, and the corresponding equipment is called a pin removal machine. Existing pin removal machines often use hydraulic cylinders to drive the ejector pins. Hydraulic cylinders provide a significant amount of driving force, but ejecting the pins from most circuit boards does not require excessive pressure. Hydraulically driven ejector pins are susceptible to bending and breaking due to excessive force. Furthermore, hydraulic stations are prone to leakage, posing a risk of contamination to the workshop. They also consume a lot of energy and have a relatively simple pressure control mechanism, making it difficult to adjust the ejection pressure according to the circuit board's conditions.

In the present PIN unpinning machine, the conveying device 12 can automatically convey the material to the workbench 11, the positioning device 20 can position the material, and the pressing device can press the material on the workbench 11, so that the material can be accurately positioned and fixed. The walking device 50 can move the PIN unpinning device 40 to each PIN unpinning position, and the driving motor 42 drives the ejector pin 41 to move up and down, so that the ejector pin 41 can accurately eject the PIN pin from the material. Compared with the traditional hydraulic drive, the driving motor 42 used in the present PIN unpinning machine to drive the ejector pin 41 to move can more flexibly adjust the size of the ejection pressure, which is helpful for detecting the PIN pin status, ensuring the cleanliness of the workshop, and reducing the risk of contamination. In addition, the force applied to the ejector pin 41 is moderate, and the ejector pin 41 is not easy to bend or break due to excessive force. Combined with the ejector pin detection device 60, it can detect in real time whether the ejector pin 41 is bent or broken, which helps to ensure the smooth progress of the PIN unpinning operation, reduce the occurrence rate of failures, and is more flexible and convenient to use.

[0031] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0032] The conveying device 12 can adopt common conveying structures such as conveyor belts and conveyor rollers, and those skilled in the art can flexibly select them according to needs.

[0033] In this embodiment, the first drive device 22 and the second drive device 32 are both cylinders, which have a simple and reliable structure, fast operation, easy control, and are also not prone to pollution. In other embodiments, the first drive device 22 and the second drive device 32 can also adopt other common drive structures such as motors.

[0034] In this embodiment, the running device 50 is an electrically driven running device, which helps to further reduce the risk of contamination, is easy to control, and is more flexible and convenient to use. In other embodiments, the running device 50 can also be driven by other driving methods such as pneumatic drive.

[0035] In this embodiment, the travel device 50 is an XY dual-axis travel device, which allows for more flexible movement of the PIN decryption device 40, extending its applicability and convenience. In other embodiments, the travel device 50 may also employ other suitable structures, such as a three-axis travel device or a single-axis travel device, as needed for different circuit boards. The travel device 50 is not limited to this embodiment. The travel device 50 has a wide range of applications, and its structure is well known to those skilled in the art, so a detailed description is omitted here.

[0036] In this embodiment, the PIN unlocking device 40 further includes a striking hammer head 43, an ejector mounting seat 44, and a guide cylinder 45. A drive motor 42 is connected to the striking hammer head 43 via a transmission mechanism 46 and can drive the striking hammer head 43 to move up and down. The ejector mounting seat 44 is movably disposed within the guide cylinder 45 and aligned vertically with the striking hammer head 43. The ejector mounting seat 44 is separated from the striking hammer head 43, and the ejector 41 is mounted on the ejector mounting seat 44. In this manner, the drive motor 42 can selectively cause the striking hammer head 43 to fall rapidly and strike the ejector mounting seat 44, thereby causing the ejector 41 to strike the PIN pin. Alternatively, the drive motor 42 can selectively cause the striking hammer head 43 to fall slowly, thereby slowly depressing the ejector 41. By reducing the speed to increase the torque, the ejector 41 is used to depress the PIN pin. This can adapt to different PIN unlocking needs and is more flexible and convenient to use. In this embodiment, the transmission mechanism 46 adopts a screw mechanism to convert the rotational output of the motor into the linear motion of the striking hammer head 43. In other embodiments, the transmission mechanism 46 can also select other commonly used transmission structures such as a rack and pinion mechanism, a worm gear mechanism, etc., but is not limited to this.

[0037] In this embodiment, the frame 10 is further provided with a barcode scanning device 70 for reading material information. The frame 10 also includes a control device for receiving the material information read by the barcode scanning device 70 and controlling the movement of the travel device 50 accordingly. This allows accurate adaptation to PIN decryption operations for different materials, facilitating ease of use and reducing failure rates. The control device and corresponding control method are well known to those skilled in the art and will not be further described here. In actual applications, a storage module may be added to store PIN position information for different materials to control the movement of the travel device 50 accordingly.

[0038] The code scanning device 70 can adopt common code scanning structures such as a camera device, a laser scanning device, etc., and the ejector detection device 60 can also adopt common detection structures such as a camera.

[0039] In this embodiment, the driving motor 42 is a servo motor, which can more flexibly control the output power and correspondingly can more flexibly and conveniently adjust the ejection pressure of the ejector pin 41.

[0040] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0041] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the scope of protection of the present invention.
