DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1 to 6 As shown, an automatic conveying mechanism for punching circuit boards includes a mounting frame 1, wherein the mounting frame 1 has two symmetrically arranged input ends 11 and output ends 12, respectively, the mounting frame 1 is provided with a plurality of conveying rollers 2, the output end 12 of the mounting frame 1 is provided with a punching device 3, and the mounting frame 1 is also provided with an adjusting mechanism 4.

[0024] When the circuit board needs to be punched, the adjusting mechanism 4 can be driven to work first, and then the width suitable for the current circuit board can be adjusted. Then the staff places the circuit board on the conveying roller 2 at the input end 11 of the mounting frame 1, and then drives the conveying roller 2 to rotate through an external power supply, so that the circuit will be conveyed toward the output end 12 of the mounting frame 1 through the action of the conveying roller 2, and then enter the punching device 3, and then the circuit board is punched by the punching device 3. The adjusting mechanism 4 can limit the circuit boards of different widths, so that the position of the circuit boards entering the punching device 3 is consistent, thereby making the qualified rate of the circuit boards after punching higher.

[0025] Reference Figure 2 As shown, the adjusting mechanism 4 includes a gantry, an adjusting plate 41 and a connecting plate 43; the gantry 42 is arranged on the mounting frame 1; the adjusting plate 41 has two and symmetrically arranged on the mounting frame 1; the connecting plate 43 is movably arranged on the gantry 42, and the gantry 42 is provided with a limiting groove 44 for the connection plate 43 to move, and the connection plate 43 is connected to the adjusting plate 41.

[0026] By driving the two connecting plates 43 to move closer to each other in the limiting grooves 44 of the gantry 42, the two adjusting plates 41 can be directly driven to move closer to each other, so that the circuit boards of different widths can be directly limited, so that the circuit boards can maintain their positions without changing when being conveyed by the conveying rollers 2, so that the qualified rate of the circuit boards after punching can be higher.

[0027] Reference Figure 3 and Figure 4 As shown, the gantry 42 is provided with a driving assembly 45, and the driving assembly 45 includes a first rotating motor 451, a rotating screw rod 454 and a second bevel gear 453; the first rotating motor 451 is arranged on the gantry 42, and a first bevel gear 452 is arranged on the output end 12 of the first rotating motor 451; the rotating screw rod 454 is arranged on the gantry 42, and the rotating screw rod 454 is threadedly connected to the connecting plate 43; the second bevel gear 453 is arranged on the rotating screw rod 454, and the second bevel gear 453 is meshedly connected with the first bevel gear 452.

[0028] By directly driving the first rotating motor 451 to work, when the output end 12 of the first rotating motor 451 rotates, it will synchronously drive the first bevel gear 452 to rotate, and then through the setting of the second bevel gear 453, it will also synchronously drive the rotating screw 454 to rotate, so that the connecting plate 43 can be directly driven to move synchronously closer to or away from each other, so that the adjusting plate 41 can maintain consistency when moving, which makes it more convenient to operate the adjusting plate 41.

[0029] Reference Figure 2 and Figure 3 As shown, a rotating mechanism 5 is arranged on the mounting frame 1, and the rotating mechanism 5 includes a sensor 13, a mounting plate 53, a limiting shaft 52 and a rotating frame 51; the sensor 13 is arranged at the input end 11 of the mounting frame 1; the mounting plate 53 is arranged on the mounting frame 1; the limiting shaft 52 is arranged above the mounting plate 53; the rotating frame 51 is arranged on the limiting shaft 52, and the rotating frame 51 can be arranged in contact with the conveying roller 2.

[0030] When the circuit board is first placed on the conveying roller 2, when the sensor 13 senses that the angle of the circuit board is incorrect, the sensor 13 will first stop the conveying roller 2, and then drive the limiting shaft 52 above the mounting plate 53 to rise first, and then make the rotating frame 51 lift the circuit board, and then drive the limiting shaft 52 to rotate, and then synchronously drive the rotating frame 51 to rotate ninety degrees to adjust the angle of the circuit board. After adjustment, drive the limiting shaft 52 to descend, so that the rotating frame 51 is away from the circuit board, and then start the conveying roller 2 to drive the circuit board to move into the punching device 3, so as to prevent the staff from placing the circuit board on the conveying roller 2. The angle is wrong, which makes the circuit board unable to be punched.

[0031] Reference Figure 3 As shown, a rotating assembly 55 is arranged on the mounting plate 53, and the rotating assembly 55 includes a second rotating motor 551 and a connecting sleeve 553; the second rotating motor 551 is arranged at the bottom of the mounting plate 53, and the output end 12 of the second rotating motor 551 can pass through the mounting plate 53, and a rotating shaft 552 is arranged on the conveying end of the second rotating motor 551; the connecting sleeve 553 is sleeved on the rotating shaft 552, and the top of the connecting sleeve 553 is connected to the bottom of the limiting shaft 52.

[0032] When it is necessary to drive the rotating frame 51 to rise and fall, the connecting sleeve 553 can be directly driven to rise and fall on the rotating shaft 552, so that the rotating frame 51 can be directly driven to rise and fall, and through the operation of the second rotating motor 551, the rotating shaft 552 can be directly and synchronously driven to rotate, and then the connecting sleeve 553 can be driven to rotate, thereby driving the rotating frame 51 to rotate, which can further improve the convenience during operation.

[0033] Reference Figure 3 and Figure 5 As shown, a lifting assembly 54 is provided on the mounting plate 53, and the lifting assembly 54 includes a lifting cylinder 541 and a connecting block 542; the lifting cylinder 541 is arranged on the top of the mounting plate 53; the connecting block 542 is connected to the connecting sleeve 553 through a bearing, and the connecting block 542 is connected to the working end of the lifting cylinder 541.

[0034] When it is necessary to drive the rotating frame 51 to rise, the lifting cylinder 541 is directly used to drive the connecting block 542 to rise and fall, which will drive the connecting sleeve 553 to rise and fall, and then directly drive the rotating frame 51 to rise and fall, which can further reduce manual operations and further improve the convenience of operation. In addition, the connecting block 542 is connected to the connecting sleeve 553 through the bearing, which will not prevent the connecting sleeve 553 from rotating.

[0035] Reference Figure 6 As shown, a plurality of positioning blocks 5521 are provided on the rotating shaft 552 , and a positioning groove 5531 cooperating with the positioning blocks 5521 is provided on the connecting sleeve 553 .

[0036] By cooperating between the positioning block 5521 and the positioning groove 5531 on the connecting sleeve 553, when the connecting sleeve 553 is lifted or lowered on the rotating shaft 552, the rotating shaft 552 can always drive the connecting sleeve 553 to rotate during rotation, and will not affect the lifting or lowering of the connecting sleeve 553 on the rotating shaft 552.

[0037] Reference Figure 5 As shown, the adjustment plate 41 is provided with a plurality of guide wheels 411 which are arranged at equal distances.

[0038] Because the circuit board is transported by the conveying roller 2, the circuit board will contact the adjustment plate 41. Through the setting of the guide wheel 411, the circuit board is in contact with the guide wheel 411 during the movement, which can reduce friction and protect the circuit board and the adjustment plate 41, thereby extending their service life.

[0039] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
