[0021] To enable those skilled in the art to better understand the technical solutions in the embodiments of this utility model, and to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be further described below in conjunction with the accompanying drawings.

[0022] It should be noted that the descriptions of these embodiments are for the purpose of aiding understanding of the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] This utility model discloses a circuit board tapping device for tapping and positioning circuit boards during the conveying process. To facilitate the explanation of the device's structure, the following description is based on the conveying device. The tapping device, conveying device, and control system together form a circuit board center positioning mechanism.

[0024] Please refer to the following: Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the circuit board center positioning mechanism in this utility model. Figure 2 yes Figure 1 The diagram shows a top view of the circuit board center positioning mechanism. The circuit board center positioning mechanism of this utility model includes a frame 1, a conveying device 2 mounted on the frame 1, a clapping device 3, dual fiber optic sensors (not shown), and a controller (not shown).

[0025] The conveying device 2 includes a drive unit (not shown), multiple conveying rollers 22 driven by the drive unit, and multiple first rollers 23 sleeved on the conveying rollers. The first rollers 23 are used to support the circuit board and prevent it from sagging and jamming. Preferably, along the conveying direction of the circuit board, the distance between the first rollers on two adjacent conveying rollers is 30-60mm, and the distance between two adjacent first rollers on the same conveying roller is 40-80mm. By optimizing the spacing of the first rollers and increasing their density, the sagging of the thin circuit board can be effectively prevented, and jamming during the conveying process can be avoided.

[0026] In this embodiment, the first roller 23 is a soft roller, such as PU material, which can reduce the wear of the roller material on the circuit board.

[0027] In this embodiment, the infeed end of the conveying device 2 is equipped with a pneumatic ejector pin 24 for separating stacked boards. When a circuit board is conveyed to the infeed end, the pneumatic ejector pin 24 extends and acts on the circuit board. After the pushing operation is completed, the pneumatic ejector pin retracts.

[0028] Please refer to the following: Figure 3 and Figure 4 ,in Figure 3 yes Figure 1 The diagram shows the structure of the clapping device in the circuit board center positioning mechanism. Figure 4 yes Figure 3The diagram shows another angle of the clapping device. The clapping device 3 includes a first slider 31 and a second slider 32 respectively disposed on both sides of the frame 1, a power unit 33 for driving the first slider 31 and the second slider 32 to move synchronously to both sides or the middle, a plurality of guide posts 34 disposed on the first slider 31 and the second slider 32, and an upper roller device 35. The guide posts 34 are distributed between two adjacent conveyor rollers, and when the clapping action is performed, the guide posts 34 contact the edge of the circuit board; the upper roller device 35 is used to lift the circuit board during the clapping action to prevent the circuit board from being damaged by friction.

[0029] In this embodiment, the power unit 33 includes a mounting base 331, a stepper motor 332 fixed to the mounting base 331, a first screw 333 connected to the output shaft of the stepper motor 332, a second screw 334 connected to the first screw 333, and a linear guide rail 335. The first screw 333 and the second screw 334 have opposite helical directions. The first slider 31 and the second slider 32 are respectively connected to the first screw 333 and the second screw 334. There are two linear guide rails 335, distributed on both sides of the first slider 31 and the second slider 32, and both the first slider and the second slider are slidably connected to the linear guide rails. When the stepper motor 332 starts, because the first screw 333 and the second screw 334 have opposite helical directions, the first slider and the second slider move synchronously to the sides or the center. During the movement, the first slider and the second slider move along the linear guide rail 335, preventing them from becoming misaligned.

[0030] Please refer to the following: Figure 5 ,yes Figure 2 The diagram shows the structure of the upper roller device in the circuit board center positioning mechanism. The upper roller device 35 includes several second rollers 352, a connecting plate 353 connected to the second rollers 352, and a cylinder 354 connected to the connecting plate 352 for driving the second rollers 352 to move up and down. The second rollers 352 are located between two adjacent conveying rollers. The upper roller device 35 is used to lift the circuit board during the tapping process to prevent the circuit board from being damaged by friction. In this embodiment, the second rollers 352 are also soft rollers, and the rotation direction of the second rollers 352 is perpendicular to the rotation direction of the first rollers 23. During the conveying process, the position of the second rollers 352 is lower than that of the first rollers 23.

[0031] In this embodiment, in order to facilitate the synchronous rise of all second rollers 352, preferably, all connecting plates 353 are connected as one unit by a support plate 355, and a cylinder 354 is connected to the support plate 355, thereby driving the second rollers 352 to move up and down by driving the support plate to move up and down.

[0032] Preferably, two sets of limiting devices 36 are provided on the linear guide rail to limit the movement of the first slider 31 and the second slider 32, respectively, to prevent the first slider / second slider from moving beyond its limit and colliding with the circuit board or frame, thereby ensuring the stability of the device operation. In this embodiment, each set of limiting devices 36 includes a first limiting block 361 and a second limiting block 362, which are correspondingly distributed on both sides of the first slider / second slider. Preferably, each set of limiting devices 36 also includes proximity switches 363 correspondingly distributed on both sides of the first slider / second slider. The proximity switches 363 are electrically connected to the controller. When the proximity switches detect that the first slider / second slider is close to the limiting block, the controller controls the stepper motor to stop working. By using the limiting blocks and proximity switches in conjunction, the accuracy of the movement position of the first slider / second slider can be improved.

[0033] In this invention, the dual fiber optic sensors, the power unit of the clapping device, the upper roller device, and the drive unit of the conveying device are electrically connected to the controller. The dual fiber optic sensors are arranged back and forth along the conveying direction of the circuit board to detect whether the circuit board has reached the clapping position and send the detection signal to the controller. When the controller receives the signal that the circuit board has reached the clapping position, it controls the drive unit of the conveying device to stop working, and the circuit board stops being conveyed; it also controls the upper roller device to move and lift the circuit board; then it controls the power unit of the clapping device to move, so that the first slider and the second slider move towards the center simultaneously until the guide post contacts the edge of the circuit board, and claps to straighten the circuit board; after the circuit board is straightened, the dual fiber optic sensors send the detection signal to the controller again, and the controller controls the upper roller device to move, driving the circuit board down until the circuit board is supported on the first roller, and then controls the power unit of the clapping device to move, driving the first slider and the second slider away from the circuit board and moving to both sides; the circuit board is no longer constrained by the clapping device, and the controller controls the drive unit of the conveying device to move again, conveying the circuit board to the next process.

[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
