Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing equipment, in particular to a double-layer PCB board code scanner. Background Art

[0002] The PCB board is one of the important components of the electronics industry. A qualified PCB board needs to go through multiple processes. In order to facilitate the tracking and inspection of the PCB board, each PCB board will have a bar code with a unique identifier. The existing code scanning devices are usually code scanners or code readers set on the production line. The code scanning device generally moves along with the track, but it is easy to break the connecting wire, resulting in code scanning failure. It is also very easy to bump into the code scanning device and damage it. Moreover, the current structure has a high manufacturing cost. In addition, sometimes the specifications and dimensions of the PCB boards conveyed on the production line will change, making the code scanning device unable to scan the bar code. It is necessary to manually adjust the position of the code scanning device, but usually it needs to be adjusted multiple times to be adjusted to the correct position. Obviously, manual adjustment is relatively troublesome. Therefore, it is urgent to solve the above problems. Content of the Utility Model

The frame is connected with a first bracket and a second bracket. The first bracket and the second bracket are parallel and arranged at intervals. Conveyors are installed on the opposite sides of the first bracket and the second bracket.

[0005] The frame is provided with a width adjustment mechanism for adjusting the distance between the first bracket and the second bracket.

[0006] A set of the code scanning mechanisms are respectively arranged on the top surface and the bottom surface of the conveyor.

[0007] Further, each code scanning mechanism includes a first sliding rod fixed on the frame. A sliding frame is slidably connected to the first sliding rod. A second sliding rod is fixed on the sliding frame. A slider is slidably connected to the second sliding rod. A code scanning head is connected to the slider.

[0010] Further, the sweeping head is slidably and rotatably connected to the slider.

[0011] Further, the width adjustment mechanism includes a first motor and a second motor. The first motor is installed on the frame, the output end of the first motor is drivingly connected with a lead screw, the first motor drives the lead screw to rotate, and a first nut adapted to the lead screw is provided on the first bracket; the second motor is installed on the second bracket, a second nut adapted to the lead screw is provided on the second bracket, and the second motor drives the second nut to rotate.

[0012] Further, the width adjustment mechanism further includes a guide rod fixedly connected to the frame. The guide rod is parallel to and spaced from the lead screw, and the first bracket and the second bracket are respectively slidably connected to the guide rod.

[0022] As Figures 1 to 4 shown, this embodiment provides a double-layer PCB board code scanner, including a frame 1 and a code scanning mechanism 2. The frame 1 is connected with a first bracket 3 and a second bracket 4. The first bracket 3 and the second bracket 4 are parallel and spaced apart, and conveyors 5 are installed on the opposite sides of the first bracket 3 and the second bracket 4;

[0023] The frame 1 is equipped with a width-adjusting mechanism 6 for adjusting the distance between the first bracket 3 and the second bracket 4;

[0024] A set of code scanning mechanisms 2 are respectively arranged on the top and bottom surfaces of the conveyor 5.

[0025] Each code scanning mechanism 2 includes a first sliding rod 21 fixedly connected to the frame 1. A carriage 22 is slidably connected to the first sliding rod 21. A second sliding rod 23 is fixedly connected to the carriage 22. A slider 24 is slidably connected to the second sliding rod 23. A code scanning head 25 is connected to the slider 24. A first locking knob 221 is connected to the carriage 22, and the first locking knob 221 is used to lock the carriage 22 on the first sliding rod 21; a second locking knob 241 is connected to the slider 24, and the second locking knob 241 is used to lock the slider 24 on the second sliding rod 23. A first scale 26 parallel to the first sliding rod 21 is fixedly connected to the frame 1, and a first indicating head 222 opposite to the first scale 26 is fixedly connected to the carriage 22; a second scale 27 parallel to the second sliding rod 23 is fixedly connected to the carriage 22, and a second indicating head 242 opposite to the second scale 27 is fixedly connected to the slider 24. Specifically, the first sliding rod 21 is arranged horizontally, and the extending direction of the second sliding rod 23 is horizontally perpendicular to the extending direction of the first sliding rod 21. Under the action of the scale and the indicating head, the position of the code scanning head 25 can be accurately indicated, and it is also convenient to adjust the code scanning head 25 to better correspond to the bar code on the PCB board, making the code scanning faster and more efficient. When adjusting the position of the code scanning head 25, only need to loosen the first locking knob 221 and the second locking knob 241, so that the carriage 22 can slide freely on the first sliding rod 21, and the slider 24 can slide freely on the second sliding rod 23. Until the indicating head indicates the correct position relative to the scale, then tighten the first locking knob 221 and the second locking knob 241.

[0026] The code scanning head 25 is slidably and rotatably connected to the slider 24. Preferably, a connecting plate 28 is fixedly connected to the slider 24. A waist-shaped hole 281 is vertically formed in the connecting plate 28. An adjusting plate 29 is fixedly connected to the code scanning head 25. A rotating shaft passing through the waist-shaped hole 281 is arranged on the adjusting plate 29, and the rotating shaft can be replaced by a screw-nut group. An arc-shaped hole 291 is formed in the adjusting plate 29. A locking bolt is connected to the adjusting plate 29. One end of the locking bolt abuts against the adjusting plate 29. The other end of the locking bolt sequentially passes through the arc-shaped hole 291 and the waist-shaped hole 281 and is connected with a locking nut (not shown in the figure). The locking bolt can be loosened to allow the rotating shaft to slide along the waist-shaped hole 281, thereby changing the position of the code scanning head 25 in the vertical direction, and allowing the locking bolt to slide along the arc-shaped hole 291, thereby changing the orientation angle of the code scanning head 25, so that the code scanning head 25 fits with the PCB board, improving the code scanning efficiency.

[0027] The width adjustment mechanism 6 includes a first motor 61 and a second motor 62. The first motor 61 is installed on the frame 1.

A second nut 65 adapted to the lead screw 63 is provided on the second bracket 4. The second motor 62 drives the second nut 65 to rotate. The width adjustment mechanism 6 further includes a guide rod 66 fixedly connected to the frame 1. The guide rod 66 is parallel to and spaced from the lead screw 63. The first bracket 3 and the second bracket 4 are respectively slidably connected to the guide rod 66. When it is necessary to adjust the distance between the first bracket 3 and the second bracket 4, the first motor 61 and the second motor 62 are operated, so as to drive the lead screw 63 and the second nut 65 to rotate. Under the cooperation of the lead screw 63 with the first nut 64 and the second nut 65, the first bracket 3 and the second bracket 4 slide on the guide rod 66, thereby changing the distance therebetween.

[0028] A housing 7 is provided outside the frame 1. Feeding ports 71 and discharging ports 72 opposite to the conveyor 5 are respectively provided on both sides of the housing 7. Support feet 73 are respectively provided at the four corners of the bottom of the housing 7. A movable window 74 is hinged to the top of the housing 7.

An operation screen and operation buttons electrically connected to the controller are provided on the front of the frame 1, making the operation more convenient and intelligent.

[0029] The specific working principle of the present utility model is as follows: Each scanning head 25 is pre-adjusted to a suitable position. After the first bracket 3 and the second bracket 4 are adjusted to a suitable distance, the specific adjustment steps can refer to the above description and will not be elaborated here one by one. Then, the device can be started. Let the PCB board be input from the feeding port 71. Under the conveyance of the conveyor 5, the PCB board will pass through the scanning head 25.
