Description

Technical Field

[0001] The utility model relates to the field of PCB board detection, in particular to a warpage measurement and sorting machine with a paper separation function. Background Art

[0002] With the rapid development of the PCB industry and surface mount technology, the distance between PCB circuits and PADs will become smaller and smaller in the future, and the components mounted on the surface will be more dense. At the same time, the deformation and bending of the PCB itself have an increasing impact on the mounting process, which has long been a major problem hindering the development of the mounting process.

[0003] For the detection of warpage, deformation and bending of PCB boards, a warpage measuring machine is generally used. In the existing warpage measuring machine, the PCB board is placed on the conveying mechanism of the machine body and passes under the detection device located at the center of the machine body, so as to detect the warpage degree of the PCB board. After the detection is completed, there are two placement boxes, NG and OK, at the rear of the machine body. According to the detection results, classification can be carried out to complete the detection of the warpage degree of the PCB board.

[0004] During the feeding and discharging processes of the existing warpage measuring machine, the PCB boards will be stacked together. However, since the PCB boards are rigid materials, when stacked together, the surface friction and the protruding structures on the surface will act together, and scratches or deformations are likely to occur, resulting in the situation that the PCB boards are functionally damaged even if they are detected as qualified. Therefore, the existing warpage measuring machine has the problem of being unable to isolate each PCB board to protect the surface of the PCB board. Summary of the Invention

[0005] The purpose of the utility model is to set a paper separation and feeding mechanism in the frame body and a placement structure to ensure that there is paper separation between each PCB board, so as to ensure that the PCB boards do not contact each other, thereby maintaining the surface structure of the boards from being damaged.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a warpage measurement and sorting machine with a paper separation function, including a frame body, a conveying mechanism arranged on the frame body, and a detection mechanism arranged on the conveying mechanism. One side of the conveying mechanism is provided with a feeding mechanism, the feeding mechanism includes a rotary adsorption structure and two paper separation storage bins, the rotary adsorption structure is arranged between the two paper separation storage bins, the rotary adsorption structure can extend into the two paper separation storage bins, the end of the conveying mechanism is provided with a discharging mechanism, the discharging mechanism includes two paper separation and feeding mechanisms and several discharging boxes, and the discharging mechanism further includes a discharging transportation structure, and the transportation track of the discharging transportation structure passes directly above the said paper separation and feeding mechanisms and the discharging boxes.

A plurality of adsorbing members are arranged on the feeding adsorption part, and the feeding three-axis moving module passes over the surface of the separator paper storage bin and the surface of the conveying mechanism.

[0009] Preferably, a rotating disk is arranged on the blanking and transporting structure, and a plurality of adsorbing members on the blanking and transporting structure are fixedly connected below the rotating disk.

[0010] Preferably, a sliding track is formed on the surface of the inner bottom plate of the separator paper feeding mechanism. An adjusting plate is slidably connected to the sliding track. A plurality of adjusting sliding openings are formed on the surface of the inner bottom plate of the separator paper feeding mechanism. The adjusting plate is divided into a plurality of adjusting rods arranged in an array, and each adjusting rod passes through each adjusting sliding opening.

[0012] Preferably, a blanking plate is arranged in the blanking box. A lifting structure is arranged on one side of the blanking plate, and the blanking plate is fixedly connected to the moving end of the lifting structure.

[0029] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Refer to Figure 1-2 , a frame body 1 outer frame is set, there is a conveying mechanism 2 inside the frame body 1, the PCB board products are placed on the conveying mechanism 2 for conveying, a detection mechanism 3 is arranged above the middle of the conveying mechanism 2, and the detection mechanism 3 detects the PCB boards placed on the conveying mechanism 2.

[0031] Refer to Figure 1-3, a feeding mechanism 4 is arranged on one side of the conveying mechanism 2. The feeding mechanism 4 can feed the surface of the conveying mechanism 2. The feeding mechanism 4 includes a rotary adsorption structure 41 and two paper separation storage bins 42. The rotary adsorption structure 41 is arranged between the two paper separation storage bins 42. The rotary adsorption structure 41 can extend into the two paper separation storage bins 42, ensuring that the rotary adsorption structure 41 operates on the products in the two paper separation storage bins 42. The rotary adsorption structure 41 includes a vertically placed rotary cylinder 411 and a rotary member 412 rotatably connected to the output end of the rotary cylinder 411. Several adsorbing members 413 are fixedly connected to the rotary member 412. The rotary member 412 has two gears facing the opening directions of the two paper separation storage bins 42, so that the rotary adsorption structure 41 can face any one of the paper separation storage bins 42 driven by the rotary member 412, pick up paper from the PCB board feeding mechanism 42 and put it down into the paper separation storage bin 42, achieving the function of cleaning waste paper during feeding.

[0032] Reference Figure 3 , a feeding part 43 is arranged above the rotary adsorption structure 41. The feeding part 43 includes a feeding three-axis moving module 431 and a feeding adsorption part 432 arranged on the feeding three-axis moving module 431. The feeding adsorption part 432 moves along three directions driven by the feeding three-axis moving module 431. Several adsorbing members 413 are arranged on the feeding adsorption part 432. The adsorbing members 413 are several electric suction cups, which can adsorb the surface of the PCB board and drive the board to move through the adsorption force. The feeding three-axis moving module 431 passes through the surface of the paper separation storage bin 42 and the surface of the conveying mechanism 2, so as to ensure that after the rotary adsorption structure 41 sucks away the paper on the surface of the PCB board in the paper separation storage bin 42, it can be adsorbed on the adsorbing members 413 of the feeding adsorption part 432 under the action of the feeding adsorption part 432 and be brought to the surface of the conveying mechanism 2. The conveying mechanism 2 is two belt modules. The PCB board moves towards the detection mechanism 3 driven by the belt modules.

[0033] Reference Figures 4-6, a blanking mechanism 5 is provided at the end of the conveying mechanism 2. The blanking mechanism 5 can blank the detected PCB boards on the conveyor belt. The blanking mechanism 5 includes two paper separating and feeding mechanisms 51 and several blanking bins 52. There are four blanking bins 52 in total, corresponding to the two paper separating and feeding mechanisms 51 respectively. The blanking bins are divided into a finished product receiving mechanism and a defective product receiving mechanism. The blanking bins 52 corresponding to each paper separating and feeding mechanism 51 respectively place the boards with NG test results and the boards with OK test results. The finished product receiving mechanism places the OK boards, and the defective product receiving mechanism places the NG boards. The blanking mechanism 5 also includes a blanking transportation structure 53. The transportation track of the blanking transportation structure 53 passes directly above the paper separating and feeding mechanism 51 and the blanking bins 52, ensuring that the blanking transportation structure 53 can adsorb the boards on the conveyor belt into the blanking bins 52 and can also place the paper separators in the paper separating and feeding mechanism 51 into the blanking bins 52, so as to realize the operation of one layer of paper separator for one product. A rotating disk 531 is provided on the blanking transportation structure 53. Several suction attachments 413 on the blanking transportation structure 53 are fixedly connected below the rotating disk 531, ensuring that the blanking transportation structure 53 can turn under the drive of the rotating disk 531 and can match the directions of the conveyor belt and the blanking bins 52 to realize the operation of positioning and placing the PCB boards into the blanking bins.

[0034] Reference Figures 4-6 , a sliding track 511 is provided on the surface of the inner bottom plate of the paper separating and feeding mechanism 51. An adjusting plate 512 is slidably connected to the sliding track 511. The adjusting plate 512 can adjust the placement space inside the paper separating and feeding mechanism 51 to place paper separators of different specifications. Several adjusting sliding openings 513 are provided on the surface of the inner bottom plate of the paper separating and feeding mechanism 51. The adjusting plate 512 is divided into several adjusting rods 514 arranged in an array and passes through each adjusting sliding opening 513. A transmission structure 515 is provided at the bottom of the bottom plate of the paper separating and feeding mechanism 51. The output end of the transmission structure 515 is fixed to the bottom of the paper separating and feeding mechanism 51. The transmission structure 515 is set as a lead screw structure. The module transmission structure 515 drives the adjusting plate 513 to move up and down. The adjusting plate 512 is manually moved and adjusted by the sliding track 511 and then fixed, automatically adjusting the internal size of the paper separating and feeding mechanism 51 according to the specifications. A blanking plate 521 is provided inside the blanking bin 52. A lifting structure 522 is provided on one side of the blanking plate 521. The blanking plate 521 is fixedly connected to the moving end of the lifting structure 522, ensuring that the blanking plate 521 can be automatically adjusted in the vertical direction to adjust the space of the blanking bin 52.

[0035] When using this mechanism, first adjust the specifications of the paper separating and feeding mechanism 51 and the blanking box 52 according to the specifications. During the feeding process, first start the rotary adsorption structure 41, pick up the paper in the PCB board feeding mechanism 42 and put it down in the paper separating storage bin 42. At this time, the feeding three-axis moving module 431 of the feeding part 43 will drive the adsorption part to adsorb the PCB board material, move it to the conveyor belt, and pass through the detection mechanism 3 for detection. During the detection process, the two blanking and transporting structures 53 will adsorb the paper in the two paper separating and feeding mechanisms 51 into the four blanking boxes 52. The detected board materials will be transported to the corresponding positions, and then put into the NG part or the OK part respectively according to the detection results through the blanking and transporting structure 53 again. At this time, the blanking and transporting structure 53 will cover the separated paper in the paper separating and feeding mechanism 51 on the surface of the PCB board material placed in the blanking box 52, so as to realize the cycle and complete the detection of the warping measurement of the PCB board material.
