[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "may" and "can" include any one of the possible combinations of the items that are being described.

[0034] Referring to Figure 1 and Figure 2 A PCB guiding, correcting, connecting and switching device includes a cabinet 100, a transmission mechanism 200 and a cooling mechanism 300. The cabinet 100 has a controller 110. The transmission mechanism 200 is installed on the cabinet 100 and located at the side of the controller 110. The transmission mechanism 200 is used for conveying a PCB. A correction stopper 400 is arranged on the transmission mechanism 200. The cooling mechanism 300 is arranged on the top of the transmission mechanism 200 and used for cooling the conveyed PCB. The controller 110 is connected with the transmission mechanism 200 and the cooling mechanism 300 respectively. A connecting plate mechanism 500 is arranged on the side of the transmission mechanism 200.

[0035] Specifically, the guiding and correcting connection device in the embodiment is arranged between the reflow soldering furnace and the next process, and is connected with the reflow soldering furnace through the connecting plate mechanism 500 on one side of the transmission mechanism 200. The PCB (square or strip-shaped) treated by reflow soldering is conveyed to the transmission mechanism 200 through the connecting plate mechanism 500, and the transmission mechanism 200 then conveys the PCB to the next process in sequence. When the square-shaped PCB is deviated in the conveying process and forms a prismatic shape, the square-shaped PCB corners can be blocked by the correction blocking rod 400 arranged on the transmission mechanism 200, so that the square-shaped PCB can be rotated in the conveying process, and then the square-shaped PCB can be returned to the correct orientation, so as to realize the guiding and correcting of the PCB. The square-shaped PCB is guided and corrected by the correction blocking rod 400, so that the square-shaped PCB can be prevented from being stuck in the conveying process, the subsequent PCB can be smoothly conveyed, and the production efficiency of the PCB can be ensured.

[0036] In addition, since the temperature of the PCB is high after being conveyed out of the reflow soldering furnace, the PCB is rapidly cooled for subsequent production and processing. Therefore, the cooling mechanism 300 is arranged on the top of the transmission mechanism 200 in the embodiment. When the transmission mechanism 200 conveys the PCB, the cooling mechanism 300 on the top can cool the PCB, so that the PCB can be normally produced and processed when conveyed to the next process, and the production efficiency of the PCB can be improved.

[0037] Meanwhile, in order to monitor the conveying of the PCB in real time, the first sensor 260 and the second sensor 270 are arranged on both sides of the transmission mechanism 200. The first sensor 260 is arranged on the side provided with the connecting plate mechanism 500. The first sensor 260 can monitor the entry of the PCB into the transmission mechanism 200, and the second sensor 270 can monitor the conveying of the PCB from the transmission mechanism 200. The first sensor 260 and the second sensor 270 can also monitor the abnormal state of the conveying of the PCB, so that the PCB can be more smoothly conveyed.

[0038] Please refer to Figures 3 to 5In order to realize the conveying of the PCB, the transmission mechanism 200 in the embodiment comprises a mounting bracket 210, a transmission shaft 220 and a conveying unit 230, a plurality of transmission shafts 220 are arranged side by side on the mounting bracket 210, and a first driving member 240 is arranged on the side of the mounting bracket 210, the first driving member 240 is connected with the plurality of transmission shafts 220 through a gear set 250, the first driving member 240 can drive the plurality of transmission shafts 220 to rotate, and the conveying unit 230 cooperates with the transmission shaft 220. After the PCB is treated by reflow soldering, it will be conveyed to the transmission shaft 220, and the PCB will be located in the conveying unit 230 for guidance, and the first driving member 240 drives the plurality of transmission shafts 220 to rotate through the gear set 250, and the transmission shaft 220 conveys the PCB when rotating, so as to realize the automatic conveying of the PCB, and the conveying unit 230 in the embodiment is provided with three groups, so that three groups of PCBs can be conveyed at the same time, so as to improve the production efficiency of the PCB.

[0039] In order to convey PCBs of different sizes, the conveying unit 230 comprises a fixed seat 231, a movable seat 232, a fixed guide rail 233, a movable guide rail 234, a lead screw 235 and a second driving member 236, the fixed seat 231 and the movable seat 232 are located below the transmission shaft 220, the fixed guide rail 233 and the movable guide rail 234 are located above the transmission shaft 220, and the fixed guide rail 233 and the movable guide rail 234 are connected with the fixed seat 231 and the movable seat 232 through the adjusting screw 237 respectively, and the movable seat 232 is connected with the middle part of the lead screw 235, and the second driving member 236 is connected with one end of the lead screw 235, the second driving member 236 can drive the lead screw 235 to rotate, thereby driving the movable seat 232 to approach or move away from the fixed seat 231.

[0040] The lead screw 235 drives the movable seat 232 to move when rotating, and the movable seat 232 drives the movable guide rail 234 to move when moving, so that the movable guide rail 234 approaches or moves away from the fixed guide rail 233, so as to adjust the distance between the movable guide rail 234 and the fixed guide rail 233, so that the distance can match PCBs of different sizes, so as to realize the conveying of PCBs of different sizes, and improve the practicability of the guiding and correcting connection equipment.

[0041] In the embodiment, in order to make the fixed guide rail 233 and the movable guide rail 234 cooperate with the transmission shaft 220, the circular arc groove 238 is arranged at the bottom end of the fixed guide rail 233 and the movable guide rail 234, the fixed guide rail 233 and the movable guide rail 234 are arranged above the transmission shaft 220 and are connected with the fixed seat 231 and the movable seat 232 through the adjusting screw 237, the fixed guide rail 233 and the movable guide rail 234 are arranged in a horn shape and form a conveying channel, the large opening is the feeding end, the small opening is the discharging end, and the correction blocking rod 400 is installed on the movable guide rail 234 and is located at one side in the conveying channel.

[0042] Since the transmission shaft 220 needs to rotate, the fixed guide rail 233 and the movable guide rail 234 can better cooperate with the transmission shaft 220 through the circular arc groove 238 and form a horn-shaped conveying channel. After the PCB board is treated by reflow soldering, it enters the conveying channel through the large opening of the feeding end and is conveyed to the next process through the small opening of the discharging end, so as to realize the automatic entering and outputting of the PCB board. The correction blocking rod 400 is installed on the movable guide rail 234, so that the correction blocking rod 400 moves with the movable guide rail 234 to realize the guiding and correction of the square PCB board of different sizes. The correction blocking rod 400 is arranged at one side in the conveying channel, so that it blocks the corners of the square PCB board and guides and corrects the PCB board.

[0043] In addition, in order to ensure the rotation of the transmission shaft 220 and the smooth conveying of the PCB board, the height of the fixed guide rail 233 and the movable guide rail 234 can be adjusted through the adjusting screw 237, so as to adjust the gap between the fixed guide rail 233 and the movable guide rail 234 and the transmission shaft 220, avoid the obstruction of the fixed guide rail 233 and the movable guide rail 234 to the transmission shaft 220, and at the same time, the fixed guide rail 233 and the movable guide rail 234 are made of black steel material. The fixed guide rail 233 and the movable guide rail 234 made of the material have low friction coefficient and long service life, and can ensure the rotation of the transmission shaft 220. The surface of the transmission shaft 220 has a knurling process, which can increase the friction coefficient of the surface of the transmission shaft 220 to prevent the PCB board from slipping during conveying, so that the PCB board is conveyed more smoothly.

[0044] Please refer to Figure 6 and Figure 7In the embodiment, in order to make the guiding and correcting connecting device better connect with the reflow soldering furnace, the connecting plate mechanism 500 is arranged on one side of the transmission mechanism 200, and the connecting plate mechanism 500 comprises a feeding plate 510, a material receiving bearing set 520, a feeding roller 530 and a power-assisted roller 540. The bottom end of the feeding plate 510 is fixed to the mounting bracket 210, and the top end is in an arc-shaped structure. The material receiving bearing set 520 is installed on the feeding plate 510. The feeding roller 530 is located on the side of the material receiving bearing set 520. The power-assisted roller 540 is arranged at the bottom of the feeding roller 530 and is in contact with the feeding roller 530 and the transmission shaft 220 respectively.

[0045] Because the transmission shaft 220 is used for conveying, the empty area between the transmission mechanism 200 and the reflow soldering furnace is large. Therefore, the upper end of the feeding plate 510 is arranged in an outwardly extending arc-shaped structure, so that the feeding plate 510 can better fit the reflow soldering furnace. The PCB board can be reasonably fed into the transmission mechanism 200 through the material receiving bearing set 520 and the feeding roller 530. In order to make the feeding roller 530 rotate, the power-assisted roller 540 is arranged below the feeding roller 530. The power-assisted roller 540 is in contact with the transmission shaft 220 in the frontmost position and the feeding roller 530 respectively. When the transmission shaft 220 in the frontmost position rotates, the power-assisted roller 540 rotates, and the feeding roller 530 rotates with the power-assisted roller 540. Through the rotation of the feeding roller 530, the PCB board can smoothly enter the transmission mechanism 200.

[0046] Finally, please refer to Figure 8 In order to realize the cooling of the PCB board, the cooling mechanism 300 in the embodiment comprises a housing 310, a cover plate 320 and a heat sink 330. The housing 310 is arranged on the top of the transmission mechanism 200. The cover plate 320 covers the housing 310, and a plurality of heat sinks 330 are arranged on the cover plate 320. When the PCB board is conveyed in the conveying channel, the heat sinks 330 blow air to the PCB board, and the temperature of the PCB board is quickly cooled through air cooling, so as to facilitate the subsequent production and processing of the PCB board and improve the production efficiency.

[0047] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Any person skilled in the art can smoothly implement the present application according to the drawings shown in the specification and the above description; however, any person skilled in the art can make some changes, modifications and equivalent changes within the scope of the technical scheme of the present application by using the above disclosed technical content, and the equivalent embodiments of the present application are still within the protection scope of the technical scheme of the present application.
