Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of PCB manufacturing, and particularly relates to a turnover material collecting device for PCB manufacturing and a material collecting method thereof. BACKGROUND

[0002] With the rapid development of the electronic industry, PCB (printed circuit board) as an indispensable component in electronic equipment, the automation and intelligence level in its manufacturing process is increasingly improved. However, the existing PCB board turnover material collecting device still has many deficiencies in design and application, especially in energy consumption, adaptability and functional diversity, which still need technical innovation and optimization.

[0003] Firstly, the PCB board turnover device on the current market generally adopts the mode of multiple motors working together in the transportation process of PCB boards from the production line to the material collecting area. Although this design can realize stable transmission and turnover of PCB boards, the simultaneous operation of multiple motors leads to high energy consumption.

[0004] Secondly, PCB boards are widely used in various fields and have different sizes. However, the existing turnover material collecting device can only adapt to PCB boards of specific sizes, and for PCB boards of different sizes, the device parts need to be replaced or adjusted, which not only increases the operation complexity, but also reduces the production efficiency.

[0005] Finally, in the PCB manufacturing process, quality detection and classification of PCB boards are the key links to ensure product quality. However, the existing turnover material collecting device mostly only has the basic functions of turnover and material collecting, and cannot perform real-time quality detection and classification of PCB boards. This leads to manual screening in the subsequent process, which not only increases the labor cost, but also affects the overall efficiency of the production line. SUMMARY

[0054] The material collecting assembly 30 comprises a detection assembly 31 arranged at the right side of the main assembly 10, a pushing assembly 32 arranged at the right bottom of the main assembly 10, and a collecting assembly 33 arranged at the right top of the main assembly 10;

[0055] The detection assembly 31 is used for detecting the front and back surfaces of the PCB board when the finished PCB board is discharged.

[0056] The pushing assembly 32 is used for pushing the PCB board which fails to pass the detection, and the collecting assembly 33 is used for collecting the PCB board.

[0057] In this embodiment, before the PCB is discharged, the moving part of the main assembly 10 is operated to adjust the distance between the main assembly 10, the linkage assembly 22 and the collecting assembly 33, so as to adjust the internal material passing space to cope with PCB boards of different sizes. Then, the PCB board enters the inside of the main assembly 10, and the front surface of the PCB board is detected by the detection part on the left side of the detection assembly 31. If the detection fails, the blocking part of the collecting assembly 33 is lowered, the PCB board is not turned over, and is directly transported to the blocking part, and then is pushed into the collecting assembly 33 by the pushing assembly 32 for collection. If the front surface detection is qualified, the conveying assembly 23 transports the PCB board to the middle part of the driving assembly 21 and the linkage assembly 22, and the driving assembly 21 drives the PCB board to be turned over and then continues to be conveyed, so as to be detected from the back surface. The back surface detection is completed by the detection part on the right side of the detection assembly 31. If the back surface detection fails, the PCB board is repeatedly subjected to the above operation, and is finally pushed into the collecting assembly 33. If the back surface detection is qualified, the PCB board is directly discharged.

[0058] Secondly, referring again to Figures 1-3 , the main assembly 10 comprises a machine body 11, the rear side of the machine body 11 is slidably connected with a moving frame 12, the bottom of the machine body 11 is fixedly connected with two groups of hydraulic rods 13, the rear ends of the hydraulic rods 13 are fixedly connected to the bottom of the moving frame 12, the front surface of the top of the machine body 11 is electrically connected with an operation table 14, the left side of the machine body 11 is provided with an inlet 15, and the inner cavity of the inlet 15 is provided with an inlet belt 16.

[0059] It should be noted that the inlet 15 is provided with a tapered inlet, which is designed to guide the offset PCB board to the middle position through the tapered inlet, so as to facilitate the subsequent operation.

[0060] The inlet belt 16 is driven to run by an external motor (not shown in the figure), and this part is a common structure of the prior art, which will not be described here.

[0061] In this embodiment, before the PCB board is discharged, the moving frame 12 will be adjusted according to the size of the PCB board to control the size of the material passing space in the turnover assembly 20 and the material collecting assembly 30, so as to ensure the smooth movement of PCB boards of different models in the main assembly 10. The adjustment of the moving frame 12 can be realized by the hydraulic rod 13, which can accurately adjust the position of the moving frame 12 under the control of the operation table 14.

[0062] Secondly, please refer again to Figures 3-8 The driving assembly 21 comprises a rotating frame 211 rotatably connected to the top of the front of the body 11. The front of the body 11 is fixedly connected with a first motor 212. The output shaft of the first motor 212 is fixedly connected to the front of the rotating frame 211. The outer circle of the rotating frame 211 in the inner cavity of the body 11 is fixedly connected with a positioning lamp 213. The inner cavity of the body 11 is fixedly connected with an electric control ring 214. The inner circle of the electric control ring 214 is electrically connected with a receiving plate 215.

[0063] The linkage assembly 22 comprises a linkage frame 221 rotatably connected to the top of the moving frame 12. The rear side of the rotating frame 211 is fixedly connected with linkage rods 222 on the upper and lower sides. The linkage rods 222 are slidingly connected to the upper and lower sides of the linkage frame 221. The top of the rotating frame 211 and the linkage frame 221 are fixedly connected with first electric push rods 223. The bottom of the first electric push rods 223 is fixedly connected with clamping plates 224.

[0064] The conveying assembly 23 comprises a second motor 231 fixedly connected to the top of the rotating frame 211. The output shaft of the second motor 231 is fixedly connected with a first gear 232. The right side top of the rotating frame 211 is rotatably connected with an upper gear rod 233. The outer circle of the first gear 232 is engaged with an upper chain 234. The bottom of the upper chain 234 is engaged with the outer circle of the front of the upper gear rod 233. The front top end of the upper gear rod 233 is fixedly connected with a second gear 235. The front middle part of the rotating frame 211 is rotatably connected with a middle gear rod 236. The tooth groove part of the middle gear rod 236 is engaged with the outer circle of the second gear 235. The right side bottom of the rotating frame 211 is rotatably connected with a lower gear rod 237. The front outer circle of the lower gear rod 237 is engaged with a lower chain 238. The top of the lower chain 238 is engaged with the outer circle of the middle gear rod 236. The right end outer circles of the upper gear rod 233 and the lower gear rod 237 are slidingly connected with linkage wheels 239. The linkage wheels 239 are rotatably connected in the inner cavity of the linkage frame 221. The outer circles of the two groups of linkage wheels 239, and the outer circles of the upper gear rod 233 and the lower gear rod 237 are rollingly connected with a belt 2310.

[0065] The conveying assembly 23 is provided with two groups, which are symmetrically distributed on the left and right sides of the rotating frame 211 and the linkage frame 221. After the device is turned over, the next group of PCB boards can be directly turned over without resetting and then working, which improves the efficiency.

[0066] It should be noted that the rotating frame 211 and the linkage frame 221 are energized by a contact type power supply device, which is designed to power the electrical components on the rotating frame 211 and the linkage frame 221;

[0067] The bottom of the clamping plate 224 is made of soft rubber material to prevent damage to the PCB during clamping;

[0068] The rear ends of the upper gear rod 233 and the lower gear rod 237 are hexagonal structure rods, which are designed to make the linkage wheel 239 not only slide on the outer circle of the upper gear rod 233 and the lower gear rod 237, but also be driven to rotate.

[0069] In this embodiment, after the PCB enters between the rotating frame 211 and the linkage frame 221, the second motor 231 starts to drive the first gear 232 and the upper chain 234 to move, and then drives the upper gear rod 233 and the second gear 235 to rotate. The second gear 235 drives the lower gear rod 237 to move through the lower chain 238, and the upper gear rod 233 and the lower gear rod 237 in the running state drive the linkage wheel 239 to rotate in the inner cavity of the linkage frame 221, and then drive the front and rear groups of belts 2310 to run together, realizing the conveying of the PCB. When the PCB reaches the middle of the rotating frame 211, the first electric push rod 223 pushes the clamping plate 224 to clamp the PCB, ensuring that it remains stable during the flipping process. The flipping action is coordinated by the linkage rod 222, and when the first motor 212 drives the rotating frame 211 to rotate, it drives the linkage frame 221 to rotate together through the linkage rod 222, flips the clamping plate 224 together with the PCB to the predetermined angle. During the flipping process, the positioning lamp 213 irradiates the receiving plate 215 in the inner circle of the electric control ring 214, and only when the specified angle is reached, the first motor 212 stops running, so that the accurate flipping angle is obtained. After the flipping is completed, the clamping plate 224 is loosened, and the PCB continues to be conveyed to the right detection part of the detection assembly 31 for back detection.

[0070] Secondly, please refer again to Figures 9-13 , the detection assembly 31 includes a visual observation instrument 311 fixedly connected to the top and left and right sides of the body 11, and the right inner cavity of the body 11 is provided with a discharge belt 312;

[0071] The pushing assembly 32 includes a second electric push rod 321 fixedly connected to the right rear side of the body 11, a lifting plate 322 fixedly connected to the top end of the second electric push rod 321, a first lifting frame 323 fixedly connected to the top surface of the lifting plate 322, and a second lifting frame 324 slidingly connected in the inner cavity of the lifting plate 322, the top of the second lifting frame 324 and the first lifting frame 323 are slidingly connected to the right side of the moving frame 12 and the body 11 respectively;

[0072] The collecting assembly 33 comprises a material collecting frame 331 fixedly connected to the top right side of the machine body 11 and the moving frame 12, the inner cavity bottom of the material collecting frame 331 is rotationally connected with a supporting plate 332, the material collecting frame 331 located on the machine body 11 is fixedly connected with a third electric push rod 333, and the bottom output end of the third electric push rod 333 is fixedly connected with a baffle 334.

[0073] It should be noted that the torsional spring (not shown in the figure) is arranged in the rotating shaft area inside the supporting plate 332, so that the supporting plate 332 always keeps the state of the end head outward in the normal state;

[0074] The bottom of the visual observation instrument 311 is provided with a plurality of groups of cameras, and the number of the cameras at the bottom of the visual observation instrument 311 that are turned on is selected according to the length of the moving of the moving frame 12, so as to cope with PCB boards of different sizes, and the number of the cameras that are turned on is reduced when the size of the PCB board is small, thereby reducing the energy consumption;

[0075] The top of the first lifting frame 323 and the second lifting frame 324 are both provided with anti-skid plates, and the anti-skid plates cannot contact the supporting plate 332, so that after the PCB board is lifted to collect the supporting plate 332 and continues to be pushed to collect, the two groups of lifting frames will not be blocked by the supporting plate 332 that is not reset during the subsequent descending;

[0076] The operation of the third electric push rod 333 is controlled by the visual observation instrument 311, and only when the unqualified PCB board is observed, the third electric push rod 333 will be lowered.

[0077] In this embodiment, before the PCB board is flipped, the front face of the PCB board is observed by the left visual observation instrument 311, if unqualified, the third electric push rod 333 will push the baffle 334 to descend, at this time, the unqualified PCB board will not be flipped, but directly transported to the left side of the baffle 334 through the belt 2310 and the discharge belt 312. At this time, the second electric push rod 321 will push the lifting plate 322 to rise, and then push the first lifting frame 323 and the second lifting frame 324 to rise, so as to lift the PCB board. In the process of lifting the PCB board, the supporting plate 332 is collected, so that the PCB board can pass smoothly, and then the PCB board continues to rise, when the PCB board is pushed to the inside of the material collecting frame 331, the supporting plate 332 is automatically reset by the action of the torsional spring, and then the two groups of lifting frames are lowered to stably place the PCB board on the supporting plate 332. If the front face of the PCB board is qualified, the back face of the PCB board is detected after being flipped, if the back face is unqualified, the above-mentioned actions are repeated to collect the PCB board. The qualified PCB board is directly discharged through the discharge belt 312, so as to realize automatic sorting.

[0078] In addition, the design of the entire device also takes into account the convenience of maintenance and operation. For example, the camera of the visual observer 311 can be quickly replaced and adjusted as needed to adapt to different model PCB detection needs. The anti-slip plate design of the lifting plate 322 and the two sets of lifting frames ensures stable clamping and transmission of the PCB in different working environments, reducing the risk of damage caused by sliding.

[0079] Embodiment 2

[0080] The embodiment provides a PCB collecting method for collecting PCBs by using any one of the above-mentioned PCB manufacturing turnover collecting devices, comprising the following steps of:

[0081] S1: Before the collecting detection, the hydraulic rod 13 drives the moving frame 12 to move, adjusts the gap with the body 11, and sends the PCB into the feeding port 15 through the feeding belt 16, and performs first detection through the left visual observer 311;

[0082] S2: When the detection is not up to standard, the third electric push rod 333 pushes the baffle 334 to descend, and the PCB that is not up to standard in the first detection is directly conveyed to the left side of the baffle 334 through the belt 2310 and the discharging belt 312, and is clamped above the supporting plate 332 through the upward pushing of the second lifting frame 324 and the first lifting frame 323;

[0083] S3: The PCB that is up to standard in the first detection is sent to the belt 2310 and is fixed through the clamp plate 224, and then is turned over through the driving assembly 21, and then is sent to the discharging belt 312, and is detected for the second time through the right visual observer 311;

[0084] S4: The PCB that is up to standard in the second detection is directly discharged through the discharging belt 312, and the PCB that is not up to standard is conveyed to the upper side of the supporting plate 332 through the steps in S2

[0085] In this embodiment, in S1, when the PCB enters the feeding port 15, the PCB is automatically aligned through the slope of the feeding port 15;

[0086] In S3, when the PCB is turned over, the PCB can be clamped first and then turned over, or the clamp plate 224 can be lowered in advance, the path of the PCB is blocked by the clamp plate 224, the PCB is directly turned over upwards after entering the range of the belt 2310, the PCB directly falls on the left side of the clamp plate 224 in the turning process, and the PCB is directly located on the right side of the clamp plate 224 after turning over, so that the turnover of the PCB is more rapid.

[0087] The working principle of the present application is that before discharging the PCB, the moving frame 12 will be adjusted according to the size of the PCB to control the size of the material passing space inside the turnover assembly 20 and the material collecting assembly 30. Before the PCB is turned over, it will be observed from the front by the left visual observation instrument 311. If it does not meet the standard, the third electric push rod 333 will push the baffle 334 to descend. At this time, the PCB that does not meet the standard will not be turned over and will be directly conveyed to the left side of the baffle 334 by the belt 2310 and the discharge belt 312. At this time, the second electric push rod 321 will push the lifting plate 322 to rise, and then push the first lifting frame 323 and the second lifting frame 324 to rise, so as to push the PCB to the top of the supporting plate 332 for collection. If the front of the PCB is detected to be qualified, the back of the PCB will be detected after being turned over. If the back is unqualified, the above-mentioned operation will be repeated to collect the PCB. The qualified PCB will be directly discharged by the discharge belt 312. During the turning over of the PCB, the PCB will enter between the rotating frame 211 and the linkage frame 221. Then the second motor 231 will be started to drive the first gear 232 and the upper chain 234 to move, and then drive the upper gear rod 233 and the second gear 235 to rotate. The second gear 235 drives the lower gear rod 237 to move through the lower chain 238, and drives the linkage wheel 239 to rotate, and then drives the front and rear groups of belts 2310 to operate together to realize the conveying of the PCB. When the PCB reaches the middle of the rotating frame 211, the first electric push rod 223 will push the clamp plate 224 to clamp the PCB. Then the first motor 212 drives the rotating frame 211 to rotate, and drives the linkage frame 221 to rotate together through the linkage rod 222, so as to clamp the PCB together with the clamp plate 224 to a predetermined angle. After the turning over is completed, the clamp plate 224 is loosened, and the PCB continues to be conveyed to the right detection part of the detection assembly 31 for back detection, so as to realize the turning over and collecting operation of the PCB.
