They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Because current circuit board inspection methods rely on manual, individual loading and inspection, they suffer from low inspection efficiency, such as... Figure 1As shown, this utility model provides a circuit board inspection and coding device, including a circuit board transfer mechanism 3, a material box transfer mechanism 5, a circuit board conveying mechanism 6, an inspection mechanism 7, and a shaping and coding mechanism 8. The circuit board conveying mechanism 6 is sequentially divided into a loading area, an inspection area, a first unloading area, a shaping and coding area, and a second unloading area. The loading area is equipped with a loading conveying mechanism 2a, the first unloading area is equipped with a good product conveying mechanism 2b, the second unloading area is equipped with a defective product conveying mechanism 2c, and at least one empty material box conveying mechanism 2d is provided. Material boxes containing stacked circuit boards are conveyed to the loading extraction position by the loading conveying mechanism 2a, and the circuit boards are extracted onto the circuit board conveying mechanism 6 by the circuit board transfer mechanism 3. The good product conveying mechanism 2b is located at the good product unloading position. The material box receives good circuit boards transferred from the circuit board conveying mechanism 6 by the circuit board transfer mechanism 3; the material box located at the defective product unloading position on the defective product conveying mechanism 2C receives defective circuit boards transferred from the circuit board conveying mechanism 6 by the circuit board transfer mechanism 3; the material box is transferred between the loading conveying mechanism 2a, the good product conveying mechanism 2b, and the defective product conveying mechanism 2C and the empty material box conveying mechanism 2d via the material box transfer mechanism 5; the detection mechanism 7 is located in the detection area, and the shaping and coding mechanism 8 is located in the coding area. The detection mechanism 7 is used to perform good product detection on the circuit board conveying mechanism 6. Good products are unloaded from the first unloading area, and defective products are notified to the shaping and coding mechanism 8 for shaping and coding, and then unloaded through the second unloading area. This invention achieves batch feeding through the cooperation of the feeding conveyor mechanism 2a and the circuit board transfer mechanism 3; it achieves batch separation of good and defective circuit boards through the cooperation of the circuit board transfer mechanism 6, the detection mechanism 7, and the shaping and coding mechanism 8; it collects good and defective circuit boards in batches through the good product transfer mechanism 2b and the defective product transfer mechanism 2C respectively; and it reduces manual intervention by transferring the material boxes through the material box transfer mechanism 5. Therefore, the circuit board detection and coding device of this invention has higher working efficiency than the prior art.

[0031] Example 1:

[0032] Specifically, such as Figure 1-6 This utility model discloses a circuit board inspection and coding device, comprising a frame 1, and a feeding conveyor 2a, a good product conveyor 2b, a defective product conveyor 2c, an empty material box conveyor 2d, a circuit board transfer mechanism 3, a circuit board lifting mechanism 4, a material box transfer mechanism 5, a circuit board conveying mechanism 6, an inspection mechanism 7, and a shaping and coding mechanism 8, all mounted on the frame 1. The circuit board conveying mechanism 6 is horizontally arranged and is sequentially divided along the conveying direction into a feeding area, an inspection area, a first unloading area, a shaping and coding area, and a second unloading area, wherein the partitions are as follows: Figure 2The components are represented by (A), (B), (C), (D), and (E) respectively; the feeding conveyor 2a is located in the feeding area, the good product conveyor 2b is located in the first unloading area, and the defective product conveyor 2C is located in the second unloading area; the feeding area, the first unloading area, and the second unloading area are respectively provided with a circuit board transfer mechanism 3 and a circuit board lifting mechanism 4, and the circuit board lifting mechanism 4 is respectively located below the feeding extraction position, the good product unloading position, and the defective product unloading position.

[0033] Furthermore, the feeding conveyor 2a, the good product conveyor 2b, the defective product conveyor 2C, the empty material box conveyor 2d, the circuit board transfer mechanism 3, the circuit board lifting mechanism 4, the material box transfer mechanism 5, the circuit board conveyor 6, the detection mechanism 7, and the shaping and coding mechanism 8 can all be controlled by a control system. The control system can be any automated control system, with a PLC (Programmable Logic Controller) being the most preferred.

[0034] Furthermore, the feeding conveyor 2a, the good product conveyor 2b, the defective product conveyor 2C, and the empty material box conveyor 2d can be arbitrarily arranged on both sides of the circuit board conveyor 6; most preferably, they are simultaneously arranged on the same side of the circuit board conveyor 6 and the material boxes are transferred through the same material box transfer mechanism 5. This arrangement can improve the transfer speed of empty material boxes, thereby improving the overall working efficiency of the equipment.

[0035] Furthermore, the feeding conveyor 2a, the good product conveyor 2b, the defective product conveyor 2C, and the empty material box conveyor 2d all include two conveying components 200 and a conveying component driver 201 mounted on the frame 1. The two conveying components 200 are arranged opposite to each other. Each conveying component 200 includes a conveyor belt 203 and a drive wheel 202 and a driven wheel 204 sleeved within the conveyor belt 203. The drive wheel 202 of each of the two conveying components 200 is coupled with the drive shaft 205 of the conveying component driver 201, and the drive wheel 202 is driven by the conveying component driver 201. The driven wheel 204 of each of the two conveying components 200 is coupled with a rotating shaft 206, allowing the driven wheel 204 to rotate. This technical solution can achieve the effect of driving two conveying components 200 synchronously with a single conveying component driver 201, thereby ensuring the smooth movement of the material box on the conveyor belt. The transmission component drive unit 201 can be of any structure, such as: motor + drive shaft, motor + drive belt + drive shaft, etc.

[0036] Furthermore, the transmission belt assembly also includes opposing baffles 207, which are located on both sides of the material box placed on the material box conveying assembly. Specifically, the baffles are disposed on the outer side of the transmission part, and the baffles 207 of the two transmission parts form a conveying channel for the material box to prevent the material box from tipping over during conveying.

[0037] Furthermore, the transmission assembly 200 also includes a drive shaft mounting base 208 and a rotating shaft mounting base 209 disposed at both ends of the baffle 207. The drive shaft mounting base 208 has two shaft holes 213 that mate with the drive shaft 205, and the rotating shaft mounting base has a limiting hole 214 that mates with the rotating shaft 206. Specifically, both the drive shaft mounting base 208 and the rotating shaft mounting base 209 have through slots for accommodating the driving wheel 202 and the driven wheel 204, respectively. Bearings are respectively provided on the two side walls of the through slot of the drive shaft mounting base 208, and the rotating shaft 206 mates with the shaft holes 213 of the bearings. The limiting hole 214 is provided on the two side walls of the through slot of the rotating shaft mounting base 209. A bearing is also provided inside the driven wheel 204. The middle section of the rotating shaft 206 mates with the bearings, and both ends of the rotating shaft 206 have flat portions that mate with the limiting holes 214.

[0038] Furthermore, the feeding conveyor 2a, the good product conveyor 2b, and the defective product conveyor 2C all include a limiting part 212. The limiting part 212 is respectively set at the feeding extraction position, the good product unloading position, and the defective product unloading position to restrict the movement of the material box. Most preferably, the limiting part 212 is a suction cup. The limiting part 212 is used to stop the material box above the circuit board lifting mechanism 4, so that the circuit board lifting mechanism 4 can push out the stacked circuit boards more smoothly, thereby preventing the material box from tilting when the circuit board lifting mechanism 4 is working.

[0039] Furthermore, the feeding conveyor 2a, the good product conveyor 2b, and the defective product conveyor 2C all include a first sensor 210 and a second sensor 211 electrically connected to the control system. The first sensor 210 is located above the circuit board lifting mechanism 4 and is used to monitor the material box information arriving above the circuit board lifting mechanism 4 to determine whether the material box has reached the feeding and extraction position. The second sensor 211 is located above the first sensor 210 and is used to monitor the circuit board pushed out by the circuit board lifting mechanism 4 to determine whether it has reached a suitable position for the circuit board transfer mechanism 3 to transfer the circuit board. Preferably, the first sensor 210 and the second sensor 211 can be any conventional position sensor. There are three first sensors 210, which are used to determine whether the employee has placed the material box, to notify the technician to place the material box if there is too few material boxes, and to monitor the lifting position arriving above the circuit board lifting mechanism 4. A bracket is provided on the outside of the baffle, and the second sensor 211 is mounted on the bracket. During material loading, when the material box is conveyed by the transfer component to the lifting position above the circuit board lifting mechanism 4, the first sensor 210 sends a signal indicating that the material box is in position. The control system then instructs the circuit board lifting mechanism 4 to push the circuit board out of the material box. When the circuit board is fully ejected, the second sensor 211 sends a signal indicating that the circuit board is completely ejected and instructs the circuit board transfer mechanism 3 to transfer the circuit board to the circuit board conveying mechanism 6. After the circuit board in the material box has been transferred, the control system instructs the material box transfer mechanism 5 to transfer the empty material box to the empty material box conveying mechanism 2d. This structure, through the circuit board transfer mechanism 3 and the circuit board lifting mechanism 4 under the control of the control system, enables rapid batch loading of circuit boards.

[0040] Furthermore, the material box transfer mechanism 5 is located between each material box conveying mechanism and the circuit board conveying mechanism 6. The material box transfer mechanism 5 includes a slide rail and a clamping assembly. The clamping assembly can move along the slide rail under the control of the control system and clamp the material box. When all the circuit boards of the material boxes in the loading area are transferred, the control system controls the material box transfer mechanism 5 to transfer the empty material box to the empty material box conveying mechanism 2d. When unloading, the control system controls the material box transfer mechanism 5 to transfer the material boxes on the empty material box conveying mechanism 2d to the good product conveying mechanism 2b and / or the defective product conveying mechanism 2C.

[0041] Furthermore, the detection mechanism 7 includes two optical detection components arranged along the length of the circuit board conveying mechanism 6. The two optical detection components are respectively arranged above and below the circuit board conveying mechanism 6. This arrangement can detect the front and back of the circuit board and transmit the detection information of the defective circuit board to the control system.

[0042] like Figures 5-6As shown, the shaping and marking mechanism 8 includes a shaping component 800 and a laser marking component 801. The shaping component 800 is disposed on the circuit board conveying mechanism 6, and the laser marking component 801 is disposed above the shaping component 800.

[0043] Further, the shaping assembly 800 includes a pressure plate 802, an extrusion plate 803, and an extrusion plate drive 804; the pressure plate is disposed on the circuit board conveying mechanism, and the pressure plate 802 and the extrusion plate 803 cooperate to extrude and shape the circuit board on the circuit board conveying mechanism (6); the pressure plate 802 has a partially light-transmitting portion for transmitting laser light from the laser marking assembly 801 to mark the circuit board; the extrusion plate 803 is located below the pressure plate 802 and is connected to the extrusion plate drive 804; the extrusion plate drive 804 is disposed on the frame 1. Most preferably, the pressure plate 802 is a light-transmitting plate that is entirely light-transmitting. When the marking mechanism receives a shaping signal, the extrusion plate drive 804 of the shaping assembly 800 rises, causing the extrusion plate 803 and the pressure plate 802 to cooperate in shaping the circuit board, while the control system can control the marking assembly to mark the aforementioned defective circuit boards. The shaping and coding mechanism 8 of this utility model can shape and code simultaneously, thus having higher working efficiency compared to traditional shaping and / or coding mechanisms. Furthermore, the structure of the shaping and coding mechanism 8 of this utility model is simpler, which can improve the integration of the overall equipment.

[0044] Working principle:

[0045] During loading, a large number of circuit boards are stacked in the material box, and the batch of material boxes are placed on the loading conveyor mechanism 2a in the loading area by manual or mechanical means. When the material box is conveyed to the loading extraction position, the first sensor 210 of the loading conveyor mechanism 2a notifies the control system to control the circuit board lifting mechanism 4 in the loading area to push the circuit board out of the material box; after the second sensor 211 detects the push-out information, it notifies the control system to control the circuit board transfer mechanism 3 in the loading area to transfer the pushed-out circuit board to the circuit board conveyor mechanism 6; under the control of the control system, the circuit board conveyor mechanism 6 conveys the circuit board to the detection area, and the detection mechanism 7 in the detection area detects the front and back information of the circuit board. The system performs testing. After testing, the control system controls the circuit board transfer mechanism 3 in the first unloading area to transfer the qualified circuit boards. During the transfer, the first sensor in the first unloading area monitors whether the empty material box has reached the good product unloading position. When it has reached the position, the first sensor notifies the control system to control the circuit board lifting mechanism 4 in the first unloading area to raise the support plate. After the second sensor 211 detects the raising information of the circuit board lifting mechanism 4, it notifies the control system to control the circuit board transfer mechanism 3 to place the circuit board on the support plate raised by the lifting mechanism. After the placement is completed, the control system controls the lifting mechanism to lower, and then repeats the above operation until the material box is full of circuit boards and is conveyed out by the good product unloading mechanism. When an empty material box needs to be replenished, the control system controls the material box transfer mechanism 5 to grab an empty material box from the empty material box conveying mechanism 2d and transfer it for replenishment. After the good circuit boards are unloaded in the first unloading area, the defective circuit boards will be conveyed to the shaping and marking area. At this time, the control system controls the shaping component 800 to shape the circuit boards that need to be shaped and controls the laser marking component 801 to mark the defective circuit boards. After the marking is completed, the defective circuit boards will be sent to the second unloading area for unloading. The unloading method in the second unloading area is the same as that in the first unloading area, and will not be described again here.

[0046] Example 2

[0047] Based on Example 1, the circuit board lifting mechanism 4 is no longer provided; the circuit board is transferred to the material box only through the circuit board transfer mechanism 3.

[0048] Example 3

[0049] Based on Embodiment 1, the good product conveying mechanism 2b and the defective product conveying mechanism 2C share the same empty material box conveying mechanism 2d. For example, it includes two empty material box conveying mechanisms 2d, one of which is located on one side of the loading conveying mechanism 2a and is used to place the empty boxes of the loading conveying mechanism 2a, and the other empty material box conveying mechanism 2d is located between the good product conveying mechanism 2b and the defective product conveying mechanism 2C and is used to place the empty material boxes for the good product conveying mechanism 2b and the defective product conveying mechanism 2C.

[0050] Example 4

[0051] Based on Embodiment 1, each of the feeding conveyor 2a, the good product conveyor 2b, and the defective product conveyor 2C is matched with an empty material box conveyor 2d.

[0052] Therefore, the circuit board inspection and marking device of this utility model has the technical effect of rapid batch inspection of circuit boards and high integration.
