Description

Technical Field

[0001] The utility model relates to the technical field of PCB board inkjet marking, in particular to a PCB board servo double-axis equidistant synchronous transport mechanism. Background Art

[0002] During the laser coding process of PCB boards, it is necessary to continuously load and unload the PCB boards. In the double-station processing equipment, each station is equipped with a separate loading and unloading mechanism, which leads to the uneven loading speed of the PCB boards on the two stations. It is necessary to wait for a certain period of time for all the PCB boards on the two stations to be on standby before starting the laser coding. Therefore, there is a certain delay in time. Even if the two loading and unloading mechanisms are synchronized through software, due to the independence of their control mechanisms, it is impossible to fully guarantee uniformity. Utility Model Content

[0003] In order to overcome the defects of the prior art, the utility model provides a PCB board servo dual-axis equal-pitch synchronous transport mechanism, which effectively solves the problem of uniformity of loading and unloading during double-station processing.

[0004] The technical solution to solve the technical problem is: a PCB board servo dual-axis equidistant synchronous transport mechanism, including a linear track, on which a first transport mechanism and a second transport mechanism are slidably arranged, the first transport mechanism and the second transport mechanism have the same structure and are connected by a connecting plate, a drive motor is arranged at the end of the linear track, the drive motor is connected to the first transport mechanism and the second transport mechanism through a synchronous wheel, so as to realize a structure in which the drive motor controls the first transport mechanism and the second transport mechanism to slide on the linear track, the first transport mechanism includes a fixed plate, on which a mounting frame is arranged via a cylinder telescopically, mounting plates are arranged side by side on the mounting frame, and suction cups are arranged on the mounting plate.

[0005] Preferably, the cross section of the linear track is groove-shaped, and the first transport mechanism and the second transport mechanism are slidably connected via the groove-shaped cross section.

[0006] Preferably, a sliding plate sliding on a linear track is provided on the back side of the fixed plate, and a vacuum device connected to a cylinder is provided on the outer side of the fixed plate.

[0007] Preferably, a guide sleeve is provided on the fixing plate, and a guide column connected to the mounting frame is slidably provided in the guide sleeve.

[0008] Preferably, the mounting frame is an aluminum alloy profile, and the mounting plate can be moved on the mounting frame and locked by screws.

[0009] Preferably, the mounting plate is provided with a slide groove, a limit plate is fixed on the slide groove by screws, a long groove is provided on the limit plate, and a suction cup is arranged at the end of the limit plate.

[0010] The utility model has a simple and ingenious structure and is easy to use. By designing an equidistant synchronous transport mechanism, simultaneous loading and unloading of double stations can be achieved. With the slot-type photoelectric structure, the position accuracy can be accurately controlled. Combined with the pneumatic suction cup, the suction stability is high and there will be no large jitter under high-speed movement, thereby ensuring the stability of the PCB board position and improving the accuracy of the board placement position.

[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 4 It can be seen that a PCB board servo dual-axis equidistant synchronous transport mechanism includes a linear track 1, on which a first transport mechanism 2 and a second transport mechanism 3 are slidably arranged. The first transport mechanism 2 and the second transport mechanism 3 have the same structure and are connected by a connecting plate 4. A driving motor 5 is arranged at the end of the linear track 1. The driving motor 5 is connected to the first transport mechanism 2 and the second transport mechanism 3 through a synchronous wheel, so that the driving motor 5 controls the first transport mechanism 2 and the second transport mechanism 3 to slide on the linear track 1. The first transport mechanism 2 includes a fixed plate 6, on which a mounting frame 8 is telescopically arranged via a cylinder 7, mounting plates 9 are arranged side by side on the mounting frame 8, and a suction cup 10 is arranged on the mounting plate 9.

[0017] When the utility model is used in a specific way,

[0018] The linear track 1 is arranged above the workstation, so that the two transport mechanisms correspond to the double workstations respectively, and the PCB boards are transported to the two workstations respectively, so as to realize synchronous loading and unloading, ensure the synchronization of work, and improve production efficiency.

[0019] The first conveying mechanism 2 and the second conveying mechanism 3 are synchronously moved through the connecting plate 4 to ensure the unification of loading and unloading. The driving motor 5 controls the movement of the first conveying mechanism 2 and the second conveying mechanism 3. The driving motor 5 adopts a servo motor 5 and is equipped with an encoder to accurately feed back the positions of the first conveying mechanism 2 and the second conveying mechanism 3 to the control system to realize real-time monitoring.

[0020] Since laser processing takes a long time, synchronous transportation with equal spacing can achieve simultaneous loading and unloading, saving time in the intermediate process and improving production efficiency.

[0021] The cross section of the linear track 1 is groove-shaped, and the first transport mechanism 2 and the second transport mechanism 3 are slidably connected via the groove-shaped cross section; a sliding plate 11 sliding on the linear track 1 is provided on the back side of the fixed plate 6 .

[0022] The driving motor 5 is connected to the first conveying mechanism 2 and the second conveying mechanism 3 through a synchronous belt. The sliding plate 11 on the back side of the fixed plate 6 of the first conveying mechanism 2 and the second conveying mechanism 3 slides with the linear track 1 through a groove section to ensure smooth sliding.

[0023] A vacuum device 12 connected to the cylinder 7 is disposed outside the fixing plate 6 . A guide sleeve 13 is disposed on the fixing plate 6 . A guide column 14 connected to the mounting frame 8 is slidably disposed inside the guide sleeve 13 .

[0024] The vacuum device 12 supplies air to the cylinder 7, and the cylinder 7 is operated to lift the fixed frame. The cooperation between the guide sleeve 13 and the guide column 14 makes the lifting of the fixed frame more stable.

[0025] The mounting frame 8 is an aluminum alloy profile, and the mounting plate 9 can move on the mounting frame 8 and be locked by screws. A slide groove 15 is provided on the mounting plate 9, and a limit plate 16 is fixed on the slide groove 15 by screws. A long groove 17 is provided on the limit plate 16, and the suction cup 10 is arranged at the end of the limit plate 16.

[0026] Two mounting plates 9 are provided and the spacing between them can be adjusted on the mounting frame 8 to adapt to the corresponding PCB board size. Similarly, the limiting plate 16 can slide on the mounting plate 9 to adjust the distance between each suction cup 10. The limiting plate 16 is also provided with a long groove 17, which can further adjust the position of the suction cup 10 to avoid the components on the PCB board that are difficult to absorb, thereby ensuring the stability of the grasping.

[0027] Compared with the prior art, the utility model has the following beneficial effects: the two transport mechanisms can move synchronously to achieve synchronous loading and unloading, save time and improve production efficiency; and through the setting of various components, the stability of PCB board absorption is increased to ensure no shaking during high-speed movement, thereby improving production efficiency.
