Description

Technical Field

[0001] This invention belongs to the field of PCB manufacturing technology and relates to a PCB welding system. Background Technology

[0002] To describe the execution of control processes, the data structure in the system that stores process management and control information is called the Process Control Block (PCB). It is part of the process entity and is the most important record-keeping data structure in the operating system. It is the most important data structure for process management and control, and each process has its own PCB. The PCB is established when the process is created and accompanies the process throughout its execution until the process is terminated.

[0003] The Process Control Block (PCB) records all the information required by the operating system to describe the current state of a process and control its execution. The PCB's role is to transform a program (including data) that cannot run independently in a multiprogramming environment into a basic unit capable of independent execution, a process that can run concurrently with other processes. In other words, the OS controls and manages concurrently executing processes based on the PCB. For example, when the OS needs to schedule a process for execution, it retrieves the process's current state and priority from its PCB; after scheduling a process, it sets the context for resuming execution based on the processor state information stored in its PCB, and locates the program and data based on the memory addresses of the program and data in its PCB; during execution, a process also needs to access its PCB to synchronize with cooperating processes, communicate, or access files; when a process pauses execution for some reason, it must save the processor environment at the breakpoint in the PCB. Therefore, throughout the entire lifecycle of a process, the system always controls it through the PCB; that is, the system perceives the process's existence based on its PCB, not anything else. Thus, the PCB is the sole identifier of a process's existence. Summary of the Invention

[0078] The fixing mechanism includes a suction cup or a pneumatic gripper.

[0079] This invention provides a PCB soldering system. During PCB soldering, the worker first manually places the PCB housing into the housing conformal groove 3. Then, a first drive mechanism moves a conveyor table 2 carrying multiple PCB housings to a PCB support plate 4. At this point, a first moving mechanism moves a first moving suction tube, causing it to use negative pressure to pick up a PCB, which is then transferred and assembled into the PCB housing. The first drive mechanism then drives the conveyor table 2 to continue moving downstream. Upon reaching the chip support 5 (as shown in the figure, not representing the actual structure), a second moving mechanism 6 drives a second moving suction tube to remove the chip from the chip support 5, which is then transferred and assembled into the corresponding position within the PCB housing. Inside; then the first drive mechanism transports the conveyor table 2 to the side of the pin support frame 7. At this time, the third moving mechanism 8 drives the fixing mechanism to fix the pins at the top, and then moves and assembles them into the PCB housing. Thus, the chip and pins are assembled in the PCB housing according to the required assembly position. Then the conveyor table 2 moves to the thermoforming soldering 9 (which is a product that can be purchased directly from the market. The specific principle and structure are the same as the thermoforming soldering 9 that can be purchased directly from the market. The specific details will not be repeated). Here, the PCB is welded to the chip and pins by thermoforming. Finally, the conveyor table 2 moves to the loading point of the conveyor table 2. Here, the worker takes out the welded product and places a new PCB housing. In this way, production can be carried out more efficiently.

[0080] During actual assembly, the positioning cylinder 26 near the edge of the support platform 10 rises and inserts the positioning pin into the positioning hole of the corresponding conveyor platform 2. At the same time, the two outer sides and the top of the conveyor platform 2 are limited by the limiting groove 25, thus ensuring the positional stability of the conveyor platform 2 (the same applies to other positioning mechanisms). Then, the worker can easily remove the soldered PCB shell from the shell contour groove 3 and attach a new PCB shell. Then, the positioning cylinder 26 moves downward, and the drive belt 11 drives the conveyor platform 2 to continue moving downstream. At this time, the bottom of both sides of the conveyor platform 2 is attached to the outer side of the corresponding support platform 10 by the anti-detachment pin 12, thus allowing the conveyor platform 2 to move forward stably.

[0081] When the conveyor platform 2 moves to the edge near the support platform 10, the bottom anti-detachment column 12 is first acted upon by the first lifting ramp 16, causing the anti-detachment column 12 to move upward and compress the elastic element 20 until the bottom of the anti-detachment column 12 is in contact with the top of the first lifting plate 15. At this time, the drive belt 11 still applies driving force to the bottom of the conveyor platform 2, while the two opposite edges of the conveyor platform 2 are guided by the guide groove 22 and change angle. When the anti-detachment column 12 moves to the edge of the drive belt 11, since the bottom of the anti-detachment column 12 is dome-shaped, when the edge of the anti-detachment column 12 acts on the side of the drive belt 11, the drive belt 11 can also drive the anti-detachment column 12 upward, causing the anti-detachment column 12 to move upward, so that the anti-detachment column 12 can pass over the drive belt 11.

[0082] Simultaneously, when the anti-detachment column 12 moves between the two support platforms 10, it moves downward under the action of gravity and the elastic force of the elastic element 20, making the bottom of the anti-detachment column 12 lower than the bottom of the conveyor platform 2. However, since the second lifting slope 18 of the second lifting plate 17 can also drive the anti-detachment column 12 upward, the side of the second lifting plate 17 can drive the anti-detachment column 12 upward again, allowing the anti-detachment column 12 to move to the top surface of the support platform 10 again. When the conveyor platform 2 moves to the middle of the transition platform 13, the drive roller rotates, which in turn drives the transition belt 14 to rotate. Thus, the side of the transition belt 14 can apply a driving force to the conveyor platform 2, allowing the conveyor platform 2 to continue moving downstream until it moves to a set of support platforms 10 on the side. Since there are two sets of support platforms 10, and there are transition platforms 13 and guide elements 21 between the two ends of the two sets of support platforms 10, the conveyor platform 2 can perform cyclical movement. This allows the conveyor 2 to cyclically remove finished products, place empty PCB housings, assemble chips, assemble pins, have the camera 23 take photos for inspection, and perform hot pressing, greatly improving production efficiency.

[0083] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
