Description
Technical Field
[0001] The present application relates to the field of PCB processing technology, and in particular to an automatic pin insertion device for a PCB board. Background Art
[0002] PIN is the pin of the original part in PCB, which is mainly used for soldering the original part in PCB. The process of PIN is to insert the PIN into the reserved hole on PCB. In the actual production and processing process, it is often necessary to insert the PIN into PCB with the help of a pin insertion device.
[0003] In the prior art, common pin insertion devices mainly include a frame, on which a magnetic field generator, a servo motor, and a control console are installed. The control console is connected to the magnetic field generator and the servo motor, and a needle box is detachably installed on the driving end of the servo motor. In the actual pin insertion process, the operator needs to pre-load a jig with a PCB board and install it on the bottom of the needle box (the jig consists of a bottom shell, a carrier plate, and a cover plate, and a receiving cavity is provided in the bottom shell. The carrier plate is installed on the bottom shell, and a number of carrier slots for placing PCB boards are provided on the carrier plate. The cover plate covers the top of the PCB board, and a through hole is reserved on the cover plate for the PIN needle to pass through), and then connect the needle box to the driving shaft of the servo motor.
[0004] During the pin insertion process, the magnetic field generator first magnetizes the PIN pin, and then changes the direction of the magnetic field of the magnetic field generator by changing the direction of the current. After the PIN pin is magnetized, there are N poles and S poles. The vibration table vibrates and drives the insertion component to vibrate together. The driving motor drives the insertion component to rotate through the transmission card shaft. The insertion component vibrates and rotates at the same time. The PIN pins in the PIN pin box can be randomly scattered on the surface of the cover plate through the above actions. According to the principle that like poles repel and opposite poles attract, the N pole of the PIN pin repels each other with the S pole of the magnetic field generator, and the S pole of the PIN pin attracts each other with the N pole of the magnetic field generator and repels each other with the S pole. The PIN pins in the PIN pin box with opposite magnetic properties to the magnetic field generator fall into the through hole of the cover plate, and are finally embedded in the reserved hole on the PCB, and the PIN pin insertion operation is completed.
[0005] However, during the actual PCB pin processing process, the inventor found that after the needle box and the jig rotated for a period of time, the PCB board loaded in the jig was likely to have reserved holes without PIN pins, requiring the operator to find the reserved holes without PIN pins and fill in the holes. However, it is rather laborious to identify and find the PCB boards without PIN pins by the naked eye, which can easily affect the efficiency of the operator in filling in the reserved holes on the PCB. There is room for improvement. Utility Model Content
[0006] In order to improve the convenience for operators to identify reserved holes without PIN pins and improve the efficiency of operators in adding PINs to PCB boards, the present application provides an automatic pin insertion device for PCB boards.
[0007] The present application provides a PCB board automatic pin insertion device adopts the following technical solution:

[0012] By adopting the above technical scheme, when the operator performs pin insertion processing on the PCB, the cover plate can be removed in advance, and after the PCB board is placed in the loading slot on the carrier board, the cover plate can be covered on the top of the carrier board. Then the operator connects the bottom shell to the needle box through the mounting hole at the bottom of the needle box, and connects and fixes the needle box and the bottom shell through the connecting piece. After the needle box is installed on the driving end of the servo motor above the base of the pin insertion device, the pin insertion device can be started through the console, the magnetic field generator emits a magnetic field, and the servo motor drives the needle box and the fixture to rotate, driving the PIN needle inside the needle box to rotate. At the same time, the electromagnetic generator is controlled to operate and change the current direction of the magnetic field generator according to the set cycle, changing the direction of the magnetic field, so that the PIN needle passes through the through hole on the cover plate and is inserted into the reserved hole on the PCB board, thereby achieving the technical effect of PIN pin insertion. When the needle box and the jig stop rotating, the operator takes off the needle box and the jig and disassembles the jig. The flexible silicone light strip in the jig can be controlled to emit light through the control button. At this time, the reserved holes without PIN needles can be more obviously and clearly exposed to the operator's field of vision, which can effectively improve the operator's identification of the reserved holes for PIN needles and improve the efficiency and convenience of the operator in replenishing needles.

[0015] Anti-slip grooves are provided on both sides of the bottom shell, and the two limiting plates are respectively engaged in the two limiting grooves.
[0016] By adopting the above technical solution, when the operator extends the jig loaded with the PCB board into the through hole and rotates the limit plate until the top of the limit plate abuts against the wall of the anti-slip groove, the extension part forms a limit on the sink on the bottom shell, and the connecting part forms a limit on the bottom of the anti-slip groove on the bottom shell, which can achieve a fixing effect on the bottom shell of the jig and effectively reduce the occurrence of the jig falling off from the bottom of the needle box during the rotation of the jig and the needle box.

[0019] Preferably, a friction plate is fixedly connected to the surface of the elastic plate.
[0020] By adopting the above technical solution, the friction plate can reduce the occurrence of the limit plate detaching from the anti-slip groove during the rotation of the needle box and the fixture.

[0024] Preferably, both side corners of the card plate are rounded.
[0025] By adopting the above technical solution, the rounded corners of the card plate can reduce the collision between the card plate and the slot corners when the card plate is inserted into the slot, thereby improving the convenience for operators to install the cover.
[0026] In summary, the automatic pin insertion device for a PCB board of the present application includes at least one of the following beneficial technical effects:
[0027] 1. Through the setting of the silicone flexible light strip installed in the bottom shell accommodating cavity of the fixture and the control button installed on the outer wall of the bottom shell, when the needle box and the fixture are rotated, the operator can remove the fixture and control the flexible silicone light strip to emit light through the control button.

[0035] The following is combined with Figure 1-5 This application is described in further detail.
[0036] Example
[0037] The present application embodiment discloses a PCB board automatic pin insertion device. Figure 1-Figure 5 It mainly includes a needle box 1 and a fixture 2. A mounting hole 12 is opened at the bottom of the needle box 1. Two connecting members 11 are installed at the bottom of the needle box 1. The two connecting members 11 are located on both sides of the mounting hole 12.
[0038] The fixture 2 includes a bottom shell 21, a carrier plate 22 and a cover plate 23. The bottom shell 21 is detachably mounted in the mounting hole 12 through two connecting members 11. A receiving cavity 211 is provided in the bottom shell 21. A placement groove 212 is formed at the top opening of the receiving cavity 211. The carrier plate 22 and the cover plate 23 are detachably mounted in the placement groove 212, and the cover plate 23 covers the top of the placement groove 212. A plurality of lamp grooves are provided at the bottom of the receiving cavity 211. Flexible silicone lamp strips 24 are respectively embedded and fixedly mounted in the plurality of lamp grooves. A control button 25 is installed on the bottom shell 21. The control button 25 is control-connected to the plurality of flexible silicone lamp strips 24.
[0039] When the operator performs pin insertion processing on the PCB, the cover plate 23 can be removed in advance. After the PCB board 3 is placed in the loading slot 221 on the carrier board 22, the cover plate 23 can be covered on the top of the carrier board 22. Then the operator connects the bottom shell 21 to the needle box 1 through the mounting hole 12 at the bottom of the needle box 1, and connects and fixes the needle box 1 and the bottom shell 21 through the connecting piece 11. After the needle box 1 is installed on the driving end of the servo motor 6 above the base 4 of the pin insertion device, the pin insertion device can be started through the console, the magnetic field generator 5 emits a magnetic field, and the servo motor 6 drives the needle box 1 and the fixture 2 to rotate, driving the PIN needle inside the needle box 1 to rotate. At the same time, the electromagnetic generator is controlled to operate and change the current direction of the magnetic field generator 5 according to the set cycle, and the magnetic field direction is changed, so that the PIN needle passes through the through hole 231 on the cover plate 23 and is inserted into the reserved hole 31 on the PCB board 3, thereby realizing the technical effect of PIN pin insertion.
[0040] When the needle box 1 and the jig 2 stop rotating, the operator takes off the needle box 1 and the jig 2 and disassembles the jig 2. The flexible silicone light strip 24 in the jig 2 can be controlled to emit light by the control button 25. At this time, the reserved holes 31 without inserted PIN needles can be more obviously and clearly exposed to the operator's field of vision, which can effectively improve the operator's recognition of the reserved holes 31 for inserted PIN needles, thereby improving the efficiency and convenience of the operator in replenishing needles.
[0041] It should be noted that, in the embodiment of the present application, the flexible silicone light strip 24 and the control button 25 are powered by a button battery module, and the button battery module is installed at the bottom of the bottom shell 21.
[0042] Reference Figure 2 and Figure 3 A sink 213 is formed on the top of both sides of the bottom shell 21, and the surface of the sink 213 is lower than the top surface of the bottom shell 21. An extension part 13 is extended inward and integrally formed on the two inner side walls opposite to the placement groove 212, and the bottom of the extension part 13 is tightly pressed against and limited to the top of the sink 213.
[0043] The connecting member 11 includes a connecting column 14 and a limiting plate 15. The connecting column 14 is rotatably connected to the bottom of the needle box 1, and the bottom of the connecting column 14 is fixedly connected to the limiting plate 15. Anti-slip grooves 214 are opened on both sides of the bottom shell 21, and the two limiting plates 15 are respectively engaged in the two limiting grooves.
[0044] When the operator extends the jig 2 loaded with the PCB board 3 into the through hole 231 and rotates the limit plate 15 until the top of the limit plate 15 abuts against the wall of the anti-slip groove 214, the extension part 13 forms a limit on the sink 213 on the bottom shell 21, and the connecting part forms a limit on the bottom of the anti-slip groove 214 on the bottom shell 21, which can achieve the effect of fixing the bottom shell 21 of the jig 2 and effectively reduce the occurrence of the jig 2 falling off from the bottom of the needle box 1 during the rotation of the jig 2 and the needle box 1.
[0045] Reference Figure 3 and Figure 4 The surface of the limiting plate 15 is fixedly connected with a spring sheet 151, which is pressed tightly between the groove wall of the anti-slip groove 214 and the limiting plate 15. The spring sheet 151 is pressed tightly between the limiting plate 15 and the groove wall of the anti-slip groove 214, which can improve the connection tightness between the limiting plate 15 and the bottom shell 21, and improve the stability of the connection between the needle box 1 and the bottom shell 21 of the fixture 2.
[0046] In the embodiment of the present application, a friction plate 152 is fixedly connected to the surface of the spring plate 151. The friction plate 152 can reduce the occurrence of the situation where the limit plate 15 is separated from the anti-slip groove 214 during the rotation of the needle box 1 and the fixture 2.
[0047] Reference Figure 2 The two ends of the cover plate 23 extend downward and are integrally formed with a card plate 232. Both sides of the bottom shell 21 are provided with card slots 215 adapted to the card plate 232. The card plate 232 is embedded in the card slot 215. The card plate 232 is limited between the inner wall of the mounting hole 12 and the groove wall of the card slot 215; a buckle 216 is fixedly connected to the groove wall of the card slot 215, and a card hole 233 adapted to the buckle 216 is provided on the card plate 232. The buckle 216 is embedded and connected in the card hole 233.
[0048] The card plates 232 on both sides of the cover plate 23 are fixed in the card slots 215 of the bottom shell 21 by the buckles 216, which can effectively improve the stability of the connection between the cover plate 23 and the bottom shell 21, and reduce the loosening and displacement of the cover plate 23 during the rotation of the fixture 2, resulting in the misalignment of the through holes 231 on the cover plate 23 and the reserved holes 31 on the PCB.
[0049] Reference Figure 2 The corners of both sides of the card plate 232 are rounded. The rounded corners of the card plate 232 can reduce the collision between the card plate 232 and the slot corners of the slot 215 during the card plate 232 extending into the slot 215, thereby improving the convenience of the operator in installing the cover plate 23.
[0050] The implementation principle of an automatic pin insertion device for a PCB board in an embodiment of the present application is as follows: by installing a silicone flexible light strip in the accommodating cavity 211 of the bottom shell 21 of the jig 2 and setting a control button 25 installed on the outer wall of the bottom shell 21, when the needle box 1 and the jig 2 are rotated, the operator can remove the jig 2 and control the flexible silicone light strip 24 to emit light through the control button 25. If there are reserved holes 31 on the PCB board 3 that are not inserted with PIN needles, the light emitted by the flexible silicone light strip 24 can pass through the reserved holes 31 and the through holes 231 on the cover plate 23 to form bright and clear light spots, which can effectively improve the operator's ability to identify the reserved holes 31 that are not inserted with PIN needles and make up the needles, and can effectively improve the operator's efficiency in making up the needles on the PCB.
[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
