[0002] During the production and processing of circuit boards, they need to be coded to help companies quickly establish new product identification standards. Generally, a special circuit board fully automatic dot-cutting and blackening machine is used for positioning and coding. The PCB laser burning & blackening equipment can connect to the data of the electrical measurement workshop. The PCB visual inspection automatically burns the bad PCS mark points and then blackens them. The mark points cannot be identified during SMT plug-in, avoiding the plug-in of bad points, replacing the original manual marking and manual point selection, and improving the overall production efficiency.

[0003] Conventional circuit boards are stacked one by one using a receiving assembly after processing. However, since the stacking area is set up with an open structure, it is convenient for subsequent operators to take out each stacked circuit board. However, in the process of stacking several circuit boards in separate stacks, as the number of stacks increases, the stacked circuit boards may topple over and produce domino-like silencing, resulting in multiple circuit boards being mixed with each other, requiring manual counting and sorting later, resulting in unnecessary work procedures.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic stacking and collecting component and a circuit board fully automatic digging and blackening machine are proposed. Utility Model Content

[0008] Furthermore, the telescopic buffer column provides structural buffering in the vertical direction for the stacking platform, and the structure of the limiting slide groove corresponds to the upper end structure of the front and rear limiting frames.

[0009] Furthermore, the stacking platform, two front and rear limit frames and two left and right limit frames are arranged to form a limit space, and the first stepper motor drives the first bidirectional screw for the two front and rear limit frames and the front and rear moving seats to move closer or farther away, and the second stepper motor drives the second bidirectional screw for the two left and right moving seats and the left and right limit frames to move closer or farther away.

[0010] Furthermore, the automatic walking frame includes a device support frame, a Z-axis track, a Y-axis self-propelled guide rail and an X-axis self-propelled guide rail.

[0015] 1. The utility model, through the coordinated operation of the first stepper motor and the second stepper motor, respectively drives the first bidirectional lead screw and the second bidirectional lead screw connected thereto to perform axial rotation in the horizontal direction. With the rotation of the second bidirectional lead screw and the first bidirectional lead screw, the front and rear limit frames and the left and right movable seats connected at both ends thereof respectively by the front and rear movable seats and the left and right movable seats can be adjusted and moved from the four directions of the stacking platform.

In addition, the front and rear limit frames and the left and right limit frames adopt staggered height settings in the horizontal direction, and at the same time, cooperate with the limit slide grooves symmetrically opened on both sides of the surface of the stacking platform, so that the front and rear limit frames avoid structural interference when adjusting. Combined with the use of the left and right limit frames, the circuit boards can be structurally limited as much as possible. Through the use of the above structure, on the one hand, flexible operation between the structures is guaranteed, and on the other hand, it can effectively ensure that the circuit boards after processing will not tip over due to excessive stacking when they are stacked in stacks. In addition, it is also avoided that the circuit boards placed in each stack will not be mixed into piles, which affects subsequent processing.

[0016] 2. The utility model, through the cooperative use of the automatic walking frame and the stacking manipulator, utilizes the horizontal forward and backward translation activity of the Y-axis self-propelled guide rail on the surface of the Z-axis track, the vertical lifting and lowering mobility of the X-axis self-propelled guide rail on the surface of the Y-axis self-propelled guide rail, and the horizontal left and right mobility of the stacking manipulator along the surface of the X-axis self-propelled guide rail using the self-propelled slider. By using the above structure, it can be ensured to the greatest extent that the stacking manipulator can flexibly stack the processed circuit boards and place them on the surfaces of various stacking tables after picking them up. At the same time, since the vacuum suction cup is installed on the side of the picking frame using a threaded adjustment rod, it can be appropriately adjusted within a certain range according to the size of the circuit board, thereby ensuring that the processed circuit boards can be picked up flexibly and stably, and stacked and stacked. The use of the above structure further ensures the operational flexibility of the device structure, thereby meeting the operational requirements of material collection and stacking as much as possible.

The structure of the limiting slide groove 203 corresponds to the upper end structure of the front and rear limiting frames 304. The stacking platform 201, the two front and rear limiting frames 304 and the two left and right limiting frames 308 are surrounded to form a limiting space, and the first stepper motor 301 drives the first bidirectional screw 302 to make the two front and rear limiting frames 304 and the front and rear moving seat 303 approach or move away, and the second stepper motor 306 drives the second bidirectional screw 305 to make the two left and right moving seats 303 move closer or farther.
