Description

Technical Field

[0001] The invention relates to a circuit board soldering device, in particular to a soldering device for assembling electronic components on a soldering pad of a groove circuit board. Background Art

[0002] The existing SMT production process refers to the use of professional automatic assembly equipment such as solder paste printers, chip mounters, and reflow soldering machines to assemble electronic components on the surface of circuit boards. It is an electronic mounting technology that directly attaches / solders electronic components such as resistors, capacitors, and inductors to the surface of circuit boards through solder. It is currently the most popular technology and process in the electronic assembly industry. After the solder paste is printed in the soldering process of electronic components, the soldering process needs to be completed through the reflow soldering process.

[0003] Currently, if Fig.13 The plurality of groove circuit boards 10 shown are arranged in a flow fixture 20. The groove circuit board 10 is a relatively small circuit board product. The soldering process is to assemble the built-in electronic components 14 on the built-in solder pads 12 in the groove 11 of the groove circuit board 10. The existing reflow soldering process uses the return air circulation in the reflow soldering furnace 4040, which cannot ideally heat the built-in solder paste 13 in the groove 11 of the groove circuit board 10, resulting in an unsatisfactory soldering process.

[0004] See Fig.15 The flat circuit board 30 and Fig.16 The groove circuit board 10 shown. Among them, the positions of the external solder pads 31 of the flat circuit board 30 and the internal solder pads 12 of the groove circuit board 10 are different. The external solder pads 31 of the flat circuit board 30 are on the plane of the flat circuit board 30, and the external electronic components 32 are evenly heated by the return air circulation of the reflow oven 40 after the soldering on the external solder pads 31 is completed by the external solder paste 33. Although the hot air generated by the return air circulation of the reflow oven 40 is higher than the external electronic components on the flat circuit board 30, the heating effect is good and the solder paste can be melted. If the groove circuit board 10 passes through the return air circulation of the reflow oven 40, because the hot air generated by the return air circulation is far away from the position of the internal solder paste 13, the solder heating effect of the internal electronic components 14 in the groove 11 is very poor, and the soldering cannot be completed smoothly. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and provide a groove hot air soldering device for a groove circuit board.

[0044] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0045] Now combined Figures 1 to 14 The invention describes a groove hot air soldering device for grooved circuit boards, comprising a dual-track feeding system 100, a multi-point hot air blowing control system 200, a converging and dividing material system 300, a detection and conveying system 400, a staggered dividing material system 500 and a rack electrical control system 600.

[0046] The dual-track feeding system 100 includes a left-side feeding conveyor belt 110 and a right-side feeding conveyor belt 120, and a left-side feeding sensor and a right-side feeding position sensor connected to a dual-track feeding control center, a left-side feeding lifting cylinder 130 and a right-side feeding lifting cylinder 140, a left-side material shifting cylinder 150 and a right-side material shifting cylinder 160, and a left-side material ejecting cylinder 170 and a right-side material ejecting cylinder 180. The left-side conveyor belt and the right-side conveyor belt respectively carry a mobile jig 700, in which a plurality of groove circuit boards 800 are arranged, and electronic components 840 are soldered to pads 820 in grooves 810 of each groove circuit board 800 through solder paste 830.

[0047] The left-side feeding sensor and the right-side feeding sensor respectively arranged at the ends of the left-side feeding conveyor belt 110 and the right-side feeding conveyor belt 120 respectively sense the mobile jig 700 in place, and the double-track feeding control center controls the left-side feeding lifting cylinder 130 and the right-side feeding lifting cylinder 140 to respectively raise and distribute the mobile jig 700 on the left-side feeding conveyor belt 110 and the right-side feeding conveyor belt 120. After the mobile jig 700 is separated from the left-side feeding conveyor belt 110 and the right-side feeding conveyor belt 120, the double-track feeding control center controls the left-side material shifting cylinder 150 and the right-side material shifting cylinder 160 to shift the material back in accordance with their respective actions, and shift the mobile jig 700 into the left-side blowing position and the right-side blowing position respectively. After the mobile jig 700 is pulled out from the left feeding conveyor belt 110 and the right feeding conveyor belt 120, the left feeding lifting cylinder 130 and the right feeding lifting cylinder 140 descend back to the origin, waiting for the next mobile jig 700 to arrive and ascend for material distribution. After the mobile jig 700 is dialed into the left blowing position and the right blowing position, the left material-discharging cylinder 150 and the right material-discharging cylinder 160 return to the origin; at the same time, the double-track feeding control center controls the left material-supporting cylinder 170 and the right material-supporting cylinder 180 respectively set to the left blowing position and the right blowing position to move respectively to support and position the mobile jig 700, so as to ensure the accuracy of the position of the mobile jig 700 dialed into the left blowing position and the right blowing position each time. After the blowing of the multi-point hot air blowing control system 200 is completed, the left material-supporting cylinder 170 and the right material-supporting cylinder 180 retreat to the origin again.

[0048] Please combine Figure 1 , 2 , 3 and Figure 6 The multi-point hot air blowing control system 200 of the present invention includes a left multi-point hot air blowing control system 200A and a right multi-point hot air blowing control system 200B which are arranged corresponding to the left blowing position and the right blowing position. The left multi-point hot air blowing control system 200A and the right multi-point hot air blowing control system 200B both include a hot air controller 210 connected to a hot air control center, a hot air gun 220 and a multi-point blowing conveying mechanism 230.

[0049] The hot air gun 220 is installed on a multi-point blowing conveying mechanism 230, and a plurality of blowing heads 240 are installed at the bottom of the hot air gun 220. The hot air gun 220 is aligned with the flow fixture 700 positioned at the left blowing position and the right blowing position through the multi-point blowing conveying mechanism 230, so that the plurality of blowing heads 240 are aligned with the grooves 810 of the plurality of groove circuit boards 800 in the flow fixture 700, and the solder paste 830 at the position of the pad 820 of the groove 810 is aligned with the hot air sequentially from left to right.

[0050] For details, please combine Figure 1 ,2 , 3, 8 and Fig.14 As shown, the multi-point blowing conveying mechanism 230 includes a connected blowing motor module and upper and lower blowing cylinders, the upper and lower blowing cylinders move left and right through the blowing motor module, and the upper and lower blowing cylinders drive the hot air gun 220 to move up and down, so that the multiple blowing heads 240 are aligned with the pads 820 in the grooves 810 of the multiple groove circuit boards 800 in the flow fixture 700 to blow and heat the cycle, so that the solder paste 830 melts and the soldering is completed. After the blowing of all the groove circuit boards 800 in the flow fixture 700 is completed, the upper and lower blowing cylinders and the blowing motor module return to the origin, and the blowing is completed.

[0051] The hot air controller 210 of the present invention is connected to the hot air gun 220 to control the hot air flow, temperature and blowing time of the hot air gun 220. The hot air controller 210 can be matched with the height between the blowing head 240 and the solder pad 820, and the size of the blowing head 240, and can set the hot air flow, temperature and blowing time according to the actual effect to be achieved, so as to control the melting effect and solder quality.

[0052] Because the front process has double-track feeding, the back mechanism needs to merge the intermediate discharge, and the merging and distributing system 300 of the present invention is used under the premise of ensuring efficiency. Figure 1 , 2 , 3 and Figure 7 The converging and distributing system 300 includes a left converging upper and lower cylinder 310, a right converging upper and lower cylinder 320 and a front-to-rear transport converging cylinder 330 connected to the converging and distributing control center. The left converging upper and lower cylinder 310 and the right converging upper and lower cylinder 320 are respectively fixedly connected to the front-to-rear transport converging cylinder 330. The left converging upper and lower cylinder 310 and the right converging upper and lower cylinder 320 are respectively fixedly connected with a left material shifting block 340 and a right material shifting block 350.

[0053] When the left multi-point hot air blowing control system 200A completes blowing the mobile jig 700 at the left blowing position, the left merging upper and lower cylinders 310 drive the left material shifting block 340 to rise, and the front and rear transport merging cylinders 330 extend to drive the left merging upper and lower cylinders 310 and the right merging upper and lower cylinders 320 to operate simultaneously, so that the left material shifting block 340 transports the mobile jig 700 at the left blowing position after blowing is completed to the middle position, and the right merging upper and lower cylinders 320 arrive at the position of the mobile jig 700 after blowing is completed at the right blowing position. After the mobile fixture 700 to be transported to the middle position is pushed out, the left side converging upper and lower cylinder 310 descends, and at the same time, the right side converging upper and lower cylinder 320 drives the right material block 350 to rise, and the front and rear transport converging cylinder 330 retracts to drive the right side converging upper and lower cylinder 320 and the left side converging upper and lower cylinder 310 to act simultaneously, so that the left side converging upper and lower cylinder 310 returns to the left side, and the right side converging upper and lower cylinder 320 drives the right material block 350 to transport the mobile fixture 700 after the blowing at the right blowing position is completed to the middle position. The front and rear transport converging cylinder 330 realizes a two-way action linkage to orderly merge the mobile fixture 700 after the blowing at the left blowing position and the right blowing position is completed to the middle. The left side converging upper and lower cylinder 310, the right side converging upper and lower cylinder 320 and the front and rear transport converging cylinder 330 repeat the above action sequence to make the mobile fixture 700 after the blowing at the left blowing position and the right blowing position be successively merged to the middle.

[0054] The dislocation material distribution system 500 of the present invention includes a push cylinder 510 and a lifting dislocation material distribution cylinder 520 connected to the dislocation material distribution control center. Each time the mobile fixture 700 after blowing at the left blowing position and the right blowing position is merged to the middle, the push cylinder 510 is operated once to push the mobile fixture 700 transported to the middle position into the conveying block of the lifting dislocation material distribution cylinder 520, and then return to the origin. The lifting dislocation material distribution cylinder 520 descends to the conveying track 1000, waiting for the detection and feeding conveying of the detection conveying system 400. After the mobile fixture 700 in the conveying block is moved out by the detection and feeding conveying mechanism 410, the lifting dislocation material distribution cylinder 520 drives the conveying block to rise to the origin to complete the descending material distribution.

[0055] The detection and conveying system 400 of the present invention includes a detection feeding and conveying mechanism 410 connected to a detection and conveying control center, a detection carrying-in mechanism 420, a multi-point carrying-out mechanism 430, a detection discharging and conveying mechanism 440 and a defective automatic discharging mechanism 450.

[0056] For details, please combine Figure 1 , 2 , 3 and Figure 8 As shown, the detection feed conveying mechanism 410 includes a connected detection feed left and right cylinders 411 and a detection feed upper and lower cylinders 412, and a rake is provided on the detection feed upper and lower cylinders 412.

[0057] When the lifting and dislocation distributing cylinder 520 has finished distributing the materials, the upper and lower cylinders 412 for detecting the feeding material move to raise the rake, and when the rake lifts up the mobile fixture 700 on the conveying block of the lifting and dislocation distributing cylinder 520, the left and right cylinders 411 for detecting the feeding material move to move the mobile fixture 700 on the conveying track 1000 in an equidistant manner, and transport it to the moving point, the upper and lower cylinders 412 for detecting the feeding material move to lower, the left and right cylinders 411 for detecting the feeding material move to return, and the upper and lower cylinders 412 for detecting the feeding material move and the left and right cylinders 411 for detecting the feeding material move to return to the origin and wait for the next transport. The upper and lower cylinders 412 for detecting the feeding material move and the left and right cylinders 411 for detecting the feeding material move repeat the above transport action until the sensor of the detection moving-in station senses that the mobile fixture 700 is in place.

[0058] Please combine Figure 1 , 2 , 3 and Fig. 9 As shown, the detection and carrying mechanism 420 includes a detection and carrying upper and lower cylinders 421, a detection and carrying clamping fixture 422 and a detection and carrying front and rear transport cylinder 423. The detection and carrying front and rear transport cylinder 423 is connected to the detection and carrying upper and lower cylinders 421, and the detection and carrying upper and lower cylinders 421 are connected to the detection and carrying clamping fixture 422.

[0059] When the sensor of the inspection and moving-in station senses that the mobile jig 700 is in place, the inspection and moving-in upper and lower cylinders 421 drive the inspection and moving-in clamping jig 422 to descend and clamp the mobile jig 700 in place, and then the inspection and moving-in upper and lower cylinders 421 rise, and at the same time the inspection and moving-in front and rear transport cylinders 423 move to transport the mobile jig 700 to the inspection station, and then the inspection and moving-in upper and lower cylinders 421 drive the inspection and moving-in clamping jig 422 to descend, and the inspection and moving-in clamping jig 422 releases the mobile jig 700. After completion, the inspection and moving-in front and rear transport cylinders 423 and the inspection and moving-in upper and lower cylinders 421 drive the inspection and moving-in clamping jig 422 to return to the origin, completing the transport action of transporting the mobile jig 700 to the inspection station.

[0060] Please combine Figure 1 , 2 , 3 and Fig.10 As shown, the multi-point moving-out mechanism 430 is connected to the good product detection system, including multi-point moving-out upper and lower cylinders 431, a multi-point moving-out clamping fixture 432 and a multi-point moving-out motor module 433. The multi-point moving-out motor module 433 is connected to the multi-point moving-out upper and lower cylinders 431, and the multi-point moving-out upper and lower cylinders 431 are connected to the multi-point moving-out clamping fixture 432.

[0061] When the inspection machine of the good product inspection system completes the inspection of the mobile jig 700 at the inspection station, the good product inspection system determines the mobile jig 700 as a good product jig 710 or a defective product jig 720, and feeds back the corresponding good product signal or defective product signal to the multi-point moving-out mechanism 430. After the multi-point moving-out upper and lower cylinders 431 of the multi-point moving-out mechanism 430 drive the multi-point moving-out clamping jig 432 to descend and clamp the mobile jig 700 that has been inspected, the multi-point moving-out upper and lower cylinders 431 rise, and at the same time, the multi-point moving-out motor module 433 operates to transport the good product jig 710 or the defective product jig 720 to the good product placement station on the transport track 1000 or the defective product placement station on the defective track 2000. The multi-point moving-out upper and lower cylinders 431 drive the multi-point moving-out clamping fixture 432 to descend, and the multi-point moving-out clamping fixture 432 releases the good fixture 710 or the defective fixture 720. After completion, the multi-point moving-out motor module 433 and the multi-point moving-out upper and lower cylinders 431 drive the multi-point moving-out clamping fixture 432 to return to the origin, completing the transport action of transporting the mobile fixture 700 to the good product placement station or the defective product placement station. The detection moving-in mechanism 420 and the multi-point moving-out mechanism 430 move in and out separately to achieve the transport function of the mobile fixture 700, reducing the impact of the mutual interference of the actions on the production efficiency.

[0062] Please combine Figure 1 , 2 , 3 and Fig.11 As shown, the material detection and discharging conveying mechanism 440 includes a connected left and right material detection and discharging cylinder 441 and an upper and lower material detection and discharging cylinder 442, and a rake is provided on the upper and lower material detection and discharging cylinder 442.

[0063] Please combine Figure 1 , 2 , 3 and Fig.11 As shown, when the good product inspection system determines the inspected mobile fixture 700 as a good product fixture 710, the multi-point carrying-out mechanism 430 transports the good product fixture 710 to the good product placement station on the conveying track 1000, the upper and lower detection and discharge cylinders 442 of the detection and discharge conveying mechanism 440 are actuated to cause the rake to rise. After rising to the point where the rake lifts up the good product fixture 710, the left and right detection and discharge cylinders 441 are actuated to cause the good product fixture 710 to be equidistantly translated and conveyed on the conveying track 1000. After being conveyed to the right position, the upper and lower detection and discharge cylinders 442 are lowered, the left and right detection and discharge cylinders 441 return, and the upper and lower detection and discharge cylinders 442 and the left and right detection and discharge cylinders 441 return to the origin to wait for the next conveyance. The upper and lower cylinders 442 for detecting material discharge and the left and right cylinders 441 for detecting material discharge repeat the above-mentioned conveying action until the good product full material sensor at the end of the conveying track 1000 senses that the material is full, and the machine stops and displays that the good product fixture 710 is full of material.
