Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to an intelligent detection and rework soldering system. Background Art

[0002] Due to its physical characteristics, there is a certain proportion of defective soldering in the wave soldering process that needs to be processed. At present, most of the wave soldering defects are still manually corrected. Because there are many wave soldering defects, low manual work efficiency, and high labor intensity, there is a chance to damage the PCB board circuit during manual repair. Moreover, the quality of manual repair cannot be guaranteed. In related technologies, manual rework soldering of the PCB board is usually carried out after the furnace, and detection is carried out in a single-track straight-through manner for repair, resulting in a long occupied space of the equipment and low repair efficiency. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the related technologies. For this purpose, the utility model provides an intelligent detection and rework soldering system, aiming to reduce the space occupation and improve the rework soldering repair efficiency.

[0047] Please refer to Figures 1 to 3 , according to the intelligent detection and rework soldering system of the embodiment of the present utility model, it includes a first transfer track 1, a second transfer track 2, a first transfer component 3 and a second transfer component 4. The first transfer track 1 is provided with a first detection device 5. The first transfer track 1 is used for transferring products, and the first detection device 5 is used for detecting defective solder joints of the products. The position of the first detection device 5 is the first working station; the second transfer track 2 is arranged side by side with the first transfer track 1. Along the transfer direction of the second transfer track 2, a flux spraying device 7 and a first rework soldering device 8 are sequentially arranged. The position of the flux spraying device 7 is the second working station, and the position of the first rework soldering device 8 is the third working station; the first transfer component 3 connects the first transfer track 1 and the second transfer track 2, and the first transfer component 3 is adapted to grab the products at the first working station to the second working station. That is to say, at least part of the first transfer component 3 is adapted to move between the first working station and the second working station; the second transfer component 4 is adapted to grab the products at the third working station to the first transfer track 1. That is to say, at least part of the second transfer component 4 is adapted to move between the third working station and the first transfer track. The second transfer component 4 can transfer the products at the third working station to the first working station for re-detection, or can transfer them to the downstream of the first working station on the first transfer track 1.

[0048] It should be noted that here, the product is taken as a circuit board as an example. In other embodiments, the product can also be other devices that need rework soldering, which is not limited herein. The first detection device 5 is an automatic optical detection device. When automatically detecting, the machine automatically scans the circuit board through a camera, collects images, compares the tested solder joints with the qualified parameters in the database, and through image processing, checks out the defects on the circuit board and marks the defects through a display or an automatic marker for subsequent repair of the circuit board by the first rework soldering device 8.

[0049] It can be understood that the first transfer track 1 and the second transfer track 2 are both formed with transfer channels. The circuit board can be clamped and placed in the transfer channel, and the circuit board is driven by rollers to move or stop along the transfer channel. The extending directions of the first transfer track 1 and the second transfer track 2 are parallel to ensure that the distances at each position between the two are equal, facilitating the same transfer distance at each position when the first transfer assembly 3 and the second transfer assembly 4 transfer the circuit board. It should be noted that the parallel here is not absolute parallel, and a certain installation error is allowed.

[0050] Exemplarily, both the first transfer assembly 3 and the second transfer assembly 4 can be robot grippers. The robot grippers are installed between the first transfer track 1 and the second transfer track 2 to identify the circuit board and transfer it between the first transfer track 1 and the second transfer track 2. Of course, the first transfer assembly 3 and the second transfer assembly 4 can also be a matching structure of a transfer track and a claw. The claw grabs the circuit board, and the claw is transferred between the first transfer track 1 and the second transfer track 2 through the transfer track.

[0051] According to the intelligent detection and rework system of the embodiment of the present invention, the product to be detected after wave soldering is transferred by the first transfer track 1. After the product reaches the first detection device 5, the first detection device 5 detects the solder joints to determine whether there are defective solder joints. If the first detection device 5 detects that the product has defective solder joints, the product is transferred to the second transfer track 2 through the first transfer assembly 3, and rework is performed on the defective solder joint positions through spraying flux and the first rework device 8. Since flux needs to be sprayed before rework, the flux spraying device 7 is arranged upstream of the first rework device 8. After the first rework device 8 completes the rework on the product, the product can be transferred to the first transfer track 1 again through the second transfer assembly 4, and the product can proceed to the next process. Since the first transfer track 1 and the second transfer track 2 are arranged side by side, the occupation of the length space is reduced, and the total length is reduced to 2.5 meters. At the same time, the automatic rework of the product is completed through the first detection device 5 and the first rework device 8 without manual operation. In addition, the first transfer track 1 transfers normal products, and the second transfer track 2 transfers defective products, realizing the diversion of normal transfer and repair transfer, effectively solving the problem of repair congestion, avoiding the situation where normal products cannot be transferred when defective products are being reworked and repaired, and improving the overall efficiency of the system.

[0052] According to an embodiment of the present invention, the transfer direction of the second transfer track 2 is the same as that of the first transfer track 1, that is, the first transfer track 1 and the second transfer track 2 transfer in the same direction, ensuring the consistency of the product transfer direction, so that the product is input from one end of the system and output from the other end. At the same time, the installation space can be saved, which is convenient for the first transfer assembly 3 to transfer the product from the first station to the second station, and is also convenient for the second transfer assembly 4 to transfer the product from the third station to the first transfer track 1.

[0053] Please refer to Figure 3 and Figure 4 According to an embodiment of the present utility model, the first transfer assembly 3 includes a first transfer track 11 and a first clamping assembly 12. The first transfer track 11 straddles the first transfer track 1 and the second transfer track 2; the first clamping assembly 12 is movably arranged on the first transfer track 11, and the first clamping assembly 12 is adapted to move between the first station and the second station, and the first clamping assembly 12 is adapted to grasp the product at the first station. In one embodiment, the first clamping assembly 12 is provided with a first flexible jaw 13.

[0054] In this embodiment, the first transfer track 11 vertically straddles the first transfer track 1 and the second transfer track 2. In this way, the transfer can be carried out along the shortest distance between the first transfer track 1 and the second transfer track 2, saving space. The first clamping assembly 12 includes a vertical movement module and a horizontal movement module. The horizontal movement module moves along the first transfer track 11, and the vertical movement module is arranged on the horizontal movement module to move along the first transfer track 11 following the horizontal movement module. At the same time, a first flexible jaw 13 is arranged on the vertical movement module for grasping the product. The first flexible jaw 13 can be made of soft rubber materials such as silica gel or rubber, or a flexible sleeve is sleeved on the jaw to prevent the product from being damaged. Exemplarily, during the process of transferring the product at the first station to the second station, the horizontal movement module moves above the first transfer track 1, and the vertical movement module descends so that the first flexible jaw 13 can grasp the product at the first transfer track 1. Subsequently, the vertical movement module rises, and the horizontal movement module moves above the second transfer track 2. At this time, the vertical movement module descends to the second station adjacent to the second transfer track 2, and the first flexible jaw 13 can put down the product, thus completing the transfer of the product.

[0055] According to an embodiment of the present utility model, the second transfer assembly 4 includes a second transfer track and a second clamping assembly. The second transfer track straddles the first transfer track 1 and the second transfer track 2; the second clamping assembly is movably arranged on the second transfer track, and the second clamping assembly is adapted to move between the third station and the first transfer track, and the second clamping assembly is adapted to grasp the product at the third station.

[0056] In one embodiment, the second clamping assembly is provided with a second flexible jaw. It can be understood that the structure of the second transfer assembly 4 is the same as or similar to the structure of the first transfer assembly 3, except that the first transfer assembly is used to transfer the product at the first station to the second station, and the second transfer assembly is used to transfer the product at the third station to the first transfer track 1, which will not be elaborated here.

[0057] Please refer to Figure 3 and Figure 5, according to an embodiment of the present utility model, the first transfer track 1 is further provided with a second detection device 6. The second detection device 6 is located downstream of the first detection device 5, and the second transfer assembly 4 transfers the product after being repaired by the first repair welding device 8 to the second detection device 6.

[0058] It can be understood that, in order to ensure the repair effect, the second detection device 6 is provided to detect the product after being repaired by the first repair welding device 8, so as to ensure that there are no defective solder joints on the circuit board after repair. Specifically, the second detection device 6 is located downstream of the first detection device 5, and after the second transfer assembly 4 transfers the repaired product to the first transfer track 1, the product can reach the second detection device 6 along with the transfer of the first transfer track 1. Alternatively, the second transfer assembly 4 can directly transfer the product after being repaired at the first repair welding device 8 to the second detection device 6, as long as the second detection device 6 can detect the repaired product. It can be understood that when the product detected by the first detection device 5 is a normal product, the normal product is transferred along the first transfer track 1 to the second detection device 6, and can be detected again by the second detection device 6 to prevent misjudgment by the first detection device 5 and improve the yield of the detected products. It should be noted that for the defective products detected by the second detection device 6, an artificial intervention area can be set at the end of the first transfer track 1, and a repair box is placed in the artificial intervention area for placing the defective products detected by the second detection device 6. For the normal products detected by the second detection device 6, the first transfer track 1 transfers them to the test station to complete the product test. The second detection device 6 is an automatic optical detection device. When automatically detecting, the machine automatically scans the circuit board through a camera, collects images, compares the tested solder joints with the qualified parameters in the database, and through image processing, checks for defects on the circuit board and marks the defects through a display or an automatic marker.

[0059] , according to an embodiment of the present utility model, the second transfer track 2 is further provided with a second repair welding device 9. The second repair welding device 9 is located upstream of the first repair welding device 8, and the second transfer assembly 4 transfers the product after being repaired by the second repair welding device 9 to the second detection device 6.

[0060] In this embodiment, the first repair welding device 8 and the second repair welding device 9 form a double-station repair to improve the repair efficiency. Exemplarily, the first repair welding device 8 and the second repair welding device 9 are integrated into a whole, can share data, and cooperate when dealing with multiple defective solder joints. For example, when there are three defective solder joints, first, the second repair welding device 9 repairs one or two of the solder joints, and the remaining solder joints are repaired by the first repair welding device 8. In this way, the second repair welding device 9 located upstream does not need to repair all the solder joints, thus avoiding the situation that the first repair welding device 8 located downstream has no defective solder joints to repair. It should be noted that the second transfer component 4 can transfer the product after being repaired by the first repair welding device 8. Since the first repair welding device 8 is located downstream of the second repair welding device 9, the product repaired by the first repair welding device 8 should also be understood as the product repaired by the second repair welding device 9.

[0061] According to an embodiment of the present invention, the first transfer track 1 is provided with a buffer area 10, and the buffer area 10 is located between the first detection device 5 and the second detection device 6.

[0062] It can be understood that the buffer area 10 is used to buffer the products conveyed out by the first detection device 5. In this way, when the second transfer component 4 transfers the products at the second transfer track 2 to the first transfer track 1, interference between the products on the two tracks can be avoided, and the system can operate normally. Specifically, when the second transfer component 4 needs to transfer the products from the second repair welding device 9 to the second detection device 6, the products conveyed out by the first detection device 5 will temporarily stay in the buffer area 10, that is, between the first detection device 5 and the second detection device 6. At this time, the products transferred from the second repair welding device 9 are preferentially placed at the second detection device 6.

[0063] In an embodiment, for the relative positions of the first transfer track 1 and the second transfer track 2, it is set that the position of the first detection device 5 is opposite to that of the flux spraying device 7, the position of the buffer area 10 is opposite to that of the first repair welding device 8, and the position of the second detection device 6 is opposite to that of the second repair welding device 9. In this way, when the first transfer component 3 transfers the products at the first detection device 5 to the flux spraying device 7, the distance is shorter, and when the second transfer component 4 transfers the products at the second repair welding device 9 to the second detection device 6, the distance is shorter, which is convenient for transfer.

[0064] Such as Figure 3As shown, according to an embodiment of the present utility model, the first detection device 5 is located below the first transfer track 1, that is, the first detection device 5 detects the product from the bottom upwards to make reasonable use of the bottom space. In other embodiments, the first detection device 5 can also be arranged on the side or above the first transfer track 1; optionally, the flux spraying device 7 is located below the second transfer track 2, that is, the flux spraying device 7 sprays flux onto the product from the bottom upwards to make reasonable use of the bottom space. In other embodiments, the flux spraying device 7 can also be arranged on the side or above the first transfer track 1 as long as it is convenient to spray flux on the product; optionally, the first repair welding device 8 is located below the second transfer track 2, that is, the first repair welding device 8 performs repair welding operations on the product from the bottom upwards to make reasonable use of the bottom space. In other embodiments, the first repair welding device 8 can also be arranged on the side or above the first transfer track 1 as long as it is convenient to perform repair welding operations on the product; optionally, the first transfer assembly 3 is located above the first transfer track 1 and the second transfer track 2 to transfer the product from above the product; optionally, the second transfer assembly 4 is located above the first transfer track 1 and the second transfer track 2 to transfer the product from above the product.

[0065] As Figure 3 As shown, in an embodiment, the first detection device 5, the flux spraying device 7 and the first repair welding device 8 are all arranged below the transfer track. In this way, the solder joints of the product can be placed downward, and the product does not need to be flipped during the repair welding process. The first transfer assembly 3 and the second transfer assembly 4 are located above the transfer track, making reasonable use of the space above and below the transfer track and improving the space utilization rate.

[0066] According to an embodiment of the present utility model, first pressing plates 14 are arranged on both sides of the first transfer track 1. The first pressing plates 14 are used to press and fix the product placed on the first transfer track 1. The first pressing plates 14 on both sides are adapted to move in opposite directions to release the product; it can be understood that the first transfer track 1 forms a transfer channel, and first pressing plates 14 are arranged on both opposite side walls of the transfer channel. The number of the first pressing plates 14 can be multiple, and the multiple first pressing plates 14 are arranged at intervals along the extension direction of the first transfer track 1 to press above the product. That is, when the product is placed on the first transfer track 1, it is stopped and limited above the product by the multiple first pressing plates 14. When the product needs to be transferred on the first transfer track 1, the first pressing plates 14 can release the product. When it is necessary to transfer the product to the second transfer track 2, the first pressing plates 14 on both sides can retreat in opposite directions to release the product, thus avoiding interfering with the transfer of the product.

[0067] Optionally, second pressing plates are provided on both sides of the second transfer track 2. The second pressing plates are used to press and fix the products placed on the second transfer track 2. The second pressing plates on both sides are adapted to move in opposite directions to release the products. It can be understood that the installation structure of the second pressing plates is the same as or similar to that of the first pressing plates 14, and will not be elaborated here.

[0068] As Figure 5 shown, according to an embodiment of the present invention, a first manual intervention area 15 is provided at the end of the first transfer track 1; it can be understood that a repair box can be arranged in the first manual intervention area 15, and the repair box is used to place products that cannot be automatically repaired, and manual intervention is carried out.

[0069] Optionally, a second manual intervention area 16 is provided at the end of the second transfer track 2. It can be understood that a repair box can also be placed in the second manual intervention area 16, which is used to place products that cannot be automatically repaired, and manual intervention is carried out. Exemplarily, when the first detection device 5 detects a defective solder joint and determines that it cannot be automatically repaired, it is transferred to the second transfer track 2 by the first transfer component 3 and conveyed to the second manual intervention area 16 by the second transfer track 2. For the products after the second soldering repair device 9 completes the soldering repair, if they are still defective products after being detected by the second detection device 6, they are conveyed to the first manual intervention area 15 by the first transfer track 1 for repair.

[0070] As Figure 1 shown, according to an embodiment of the present invention, the intelligent detection and soldering repair system further includes a housing 17. The housing 17 is provided with an accommodation space. The first transfer track 1 and the second transfer track 2 are installed in the accommodation space. The housing 17 is provided with a first window 18 corresponding to the first transfer track 1, and the housing 17 is provided with a second window 19 corresponding to the second transfer track 2. It can be understood that the housing 17 plays a protective role to prevent external sundries from entering the accommodation space and avoid interference or equipment damage to the detection process and the soldering repair process. The housing 17 is provided with first windows 18 at both ends of the first transfer track 1 to facilitate the conveying and output of products. Similarly, the housing 17 is provided with second windows 19 at both ends of the second transfer track 2.

[0071] According to an embodiment of the present invention, a control terminal 20 is provided on the outer wall surface of the housing 17. The control terminal 20 is electrically connected to the entire system, and the control terminal 20 is a computer to monitor and control the operation of the entire system.

[0072] The following combines Figure 5 and Figure 6 to introduce an embodiment of the working process of the intelligent detection and soldering repair system of the present invention:

[0073] This system is composed of three sets of equipment. The first detection device 5 is a bottom AOI (Automated Optical Inspection), the second detection device 6 is an AOI rechecking machine, and the first soldering repair device 8 and the second soldering repair device 9 can be integrated into one device. As Figure 6 shown, the bottom AOI mainly detects the soldering quality and directly passes the boards with OK detection results to the next station. As Figure 5 shown, that is, the circuit boards that are detected normally by the first detection device 5 are conveyed downward along the first conveyor track 1. The circuit boards that are detected NG and can be repaired are picked up by a manipulator and transferred to the second conveyor track 2, and then flux is sprayed on the positions that need to be repaired. The first soldering repair device 8, the second soldering repair device 9, and the AOI rechecking machine receive the circuit boards that are detected NG and can be repaired and perform automatic repair. The first soldering repair device 8 and the second soldering repair device 9 form a two-station repair, which can improve the efficiency. After the repair is completed, the circuit boards are transferred by a manipulator to the second detection device 6 for inspection of the repair results. After passing the inspection OK, they are directly conveyed through the NG buffer machine to the subsequent stations (usually test stations). For the circuit boards that are detected NG and cannot be repaired, they are directly conveyed to the NG buffer station for manual intervention.
