DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The circuit board pin cutting device according to the embodiment of the utility model is described below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the circuit board pin shearing device of the embodiment of the utility model may include a baffle 100 , a slide rail 200 , a limit plate 300 , a lifting device 400 and a shearing device 500 .

[0029] The two slide rails 200 are arranged opposite to each other and fixed on the baffle 100 . The two slide rails 200 are located at the same height level. Support legs 201 are arranged at the bottom of the slide rails 200 to support the slide rails 200 .

[0030] The circuit board 600 faces upward with its back side, and is movably disposed between the two slide rails 200 .

[0031] It should be noted that the front side of the circuit board 600 is also called the component side, which is the side where electronic components are installed; the back side of the circuit board 600, also called the welding side, is the side where the component pins are welded, that is, when the back side of the circuit board 600 faces upward, the pins 601 are vertically upward.

[0032] The limiting plate 300 is disposed directly above the circuit board 600 through the lifting device 400 , and a plurality of through holes 301 are formed on the limiting plate 300 , and the plurality of through holes 301 correspond one-to-one to the plurality of pins 601 on the circuit board 600 .

[0033] It should be noted that when the relevant staff pushes the circuit board 600 along the slide rail 200 to the baffle 100, the baffle 100 limits the circuit board 600. When the limiting plate 300 descends, the through hole 301 passes through the corresponding pin 601 and exposes the pin 601 on the limiting plate 300.

[0034] The shearing device 500 is disposed on the limiting plate 300 , and the shearing device 500 includes a moving structure 510 , a stabilizing structure 520 , a connecting plate 530 and a cutting knife 540 .

[0035] The movable structure 510 and the stabilizing structure 520 are respectively arranged on both sides of the limiting plate 300 , the two ends of the connecting plate 530 are respectively connected to the movable ends of the movable structure 510 and the stabilizing structure 520 , and the cutting knife 540 is arranged on the connecting plate 530 .

[0036] It should be noted that the movable structure 510 can drive the connecting plate 530 to move on the stable structure 520 , and the stable structure 520 can make the connecting plate 530 more stable when moving.

[0037] As a possible situation, the cutting knife 540 can be detachably arranged on the connecting plate 530. Specifically, the cutting knife 540 can be locked on the connecting plate 530 by means of bolt locking, so as to facilitate the replacement of the cutting knife 540 at a later time.

[0038] Specifically, if Figure 1 and Figure 5 As shown, when the relevant staff cuts the pins 601 of the circuit board 600, first, the relevant staff turns the back of the circuit board 600 upward and moves both sides of the circuit board 600 along the slide rails 200 respectively until the circuit board 600 is blocked by the baffle 100.

[0039] At this time, the relevant staff can control the lifting device 400 to lower the limit plate 300. When the limit plate 300 is lowered, the pins 601 pass through the corresponding through holes 301 and are exposed on the limit plate 300.

[0040] Then, the relevant staff can control the movable structure 510 so that the movable structure 510 drives the connecting plate 530 and the cutting knife 540 to move. When the cutting knife 540 moves, the pins 601 exposed on the limiting plate 300 are sheared.

[0041] After the cutting is completed, the relevant staff controls the cutting device and the lifting device 400 to reset, pushes the circuit board 600 along the slide rail 200, and puts in the next circuit board 600, and repeats this process.

[0042] In one embodiment of the present invention, the slide rail 200 is a U-shaped frame, and the opening ends of the two slide rails 200 are arranged opposite to each other, and the two sides of the circuit board 600 are respectively arranged in the openings of the corresponding slide rails 200.

[0043] It should be noted that the opening width of the slide rail 200 is consistent with the thickness of the side plate of the circuit board 600 , so the circuit board 600 can be more stable when moving between the two slide rails 200 .

[0044] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the lifting device 400 includes a first driving motor 410 , a bevel gear set 420 , a screw rod 430 and a nut sleeve 440 .

[0045] Among them, the screw 430 is rotatably set on the top of the slide rail 200 and extends vertically upward, the first drive motor 410 is set on the baffle 100, the output end of the first drive motor 410 is meshed and connected with the top of the screw 430 through the bevel gear set 420, and the nut sleeve 440 is set on the screw 430 and embedded in the limit plate 300.

[0046] It should be noted that by starting the first drive motor 410, the bevel gear set 420 can transmit power to the screw 430, so that the screw 430 rotates, thereby moving the nut sleeve 440 on the screw 430, and further driving the limit plate 300 to move.

[0047] In addition, in order to further provide stability when the limiting plate 300 is lifted or lowered, the lifting device 400 further includes a slide bar 401 , wherein the slide bar 401 is vertically arranged on the slide rail 200 and extends upward, and the limiting plate 300 is slidably connected to the slide bar 401 .

[0048] As a possible situation, there are three slide bars 401, one of which is arranged on the slide rail 200 where the screw rod 430 is located, and the other two are arranged on another slide rail 200. Then, when the limit plate 300 is raised or lowered, it slides along the slide bar 401, so that the limit plate 300 is raised or lowered with higher stability.

[0049] In addition, in order to further improve the stability of the screw rod 430 , a fixing frame 431 is further provided on the baffle 100 , and the screw rod 430 can rotate through the fixing frame 431 .

[0050] To clearly explain the above embodiment, in one embodiment of the present invention, the bevel gear set 420 includes two mutually meshing bevel gears, one of which is connected to the output end of the first drive motor 410 , and the other is coaxially connected to the screw 430 .

[0051] Specifically, when the relevant staff controls the lifting device 400 to drive the limit plate 300 to lift and lower, first, the relevant staff starts the first drive motor 410, and the first drive motor 410 drives the screw 430 to rotate through the bevel gear set 420, and the limit plate 300 follows the nut sleeve 440 to lift and lower on the screw 430. At the same time, the limit plate 300 slides with the slide rod 401.

[0052] Relevant staff can control the lifting height of the limit plate 300 by controlling the lifting device 400 to control the reserved length of the root of the pin 601 .

[0053] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the moving structure 510 includes a first mounting frame 511 , a lead screw 512 , a lead screw slider 513 and a second driving motor 514 .

[0054] The first mounting frame 511 is disposed on the limiting plate 300 , the lead screw 512 is rotatably disposed on the first mounting frame 511 , the lead screw slider 513 is disposed on the lead screw 512 , and the output end of the second driving motor 514 is connected to the lead screw 512 .

[0055] It should be noted that relevant staff can turn on the second drive motor 514 to rotate the screw 512, and the screw slider 513 moves on the screw 512, and drives the connecting plate 530 and the cutting knife 540 to move. While the cutting knife 540 moves on the limit plate 300, it shears the exposed pins on the limit plate 300.

[0056] To clearly explain the above embodiment, in one embodiment of the present invention, the stabilizing structure 520 includes a second mounting frame 521 , a stabilizing rod 522 and a sliding sleeve 523 .

[0057] The second mounting frame 521 is disposed on the limiting plate 300, the stabilizing rod 522 is disposed between the second mounting frames 521, and the sliding sleeve 523 is sleeved and slidably disposed on the stabilizing rod 522.

[0058] The two ends of the connecting plate 530 are respectively connected to the lead screw slider 513 and the sliding sleeve 523 .

[0059] It should be noted that when the movable structure 510 drives the connecting plate 530 to move, the connecting plate 530 drives the sliding sleeve 523 to move on the stabilizing rod 522 to further improve the stability of the movement of the connecting plate 530 and ensure that the cutting knife 540 is more stable when shearing the pin 601.

[0060] In summary, according to the circuit board pin cutting device of the embodiment of the utility model, the position of the limit plate 300 can be adjusted by the lifting device 400, and the pin 601 exposed on the limit plate 300 can be cut by the cutting device 500. This not only ensures the reserved length of the root of the pin 601 when cutting, but also has higher efficiency than manual operation. In addition, it has lower cost and is more suitable for small and medium-sized factories producing circuit boards.
