Description

Technical Field

[0001] The invention belongs to the technical field of PCB manufacturing, and in particular relates to a turning and receiving device for PCB manufacturing and a receiving method thereof. Background Art

[0002] With the rapid development of the electronics industry, PCB (printed circuit board) is an indispensable component of electronic equipment, and the level of automation and intelligence in its manufacturing process is increasing. However, the existing PCB board flipping and collecting device still has many shortcomings in design and application, especially in terms of energy consumption, adaptability and functional diversity, and technical innovation and optimization are still needed.

[0003] First, the PCB board flipping devices currently on the market generally use multiple motors working together during the transportation of PCB boards from the production line to the receiving area. Although this design can achieve stable transmission and flipping of PCB boards, the simultaneous operation of multiple motors leads to higher energy consumption.

[0004] Secondly, PCB boards have a wide range of applications and come in various sizes. However, existing flipping and receiving devices can only accommodate PCB boards of a specific size. For PCB boards of different sizes, it is necessary to replace or adjust equipment components, which not only increases the complexity of operation but also reduces production efficiency.

[0005] Finally, in the PCB manufacturing process, quality inspection and classification of PCB boards are key links to ensure product quality. However, most of the existing flipping and receiving devices only have basic flipping and receiving functions, and cannot perform real-time quality inspection and classification of PCB boards. This results in manual screening in subsequent processes, which not only increases labor costs, but also affects the overall efficiency of the production line. Summary of the invention

The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0050] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0051] Example 1

[0052] Please refer to the attached Figure 1-Figure 13 As shown, it is the first embodiment of the present invention, which provides a turning and collecting device for PCB manufacturing, including a main body component 10, and a turning component 20 is arranged in the middle of the main body component 10;

[0053] The material turning assembly 20 includes a driving assembly 21, a linkage assembly 22 is disposed at the rear side of the driving assembly 21, and a conveying assembly 23 is disposed in the inner cavity of the driving assembly 21;

[0054] The material receiving assembly 30 includes a detection assembly 31 disposed on the right side of the main assembly 10, a material pushing assembly 32 is disposed at the right bottom of the main assembly 10, and a collection assembly 33 is disposed on the top right side of the main assembly 10;

[0055] When the manufactured PCB board is discharged, the detection component 31 is used to detect the front and back sides of the PCB board. During the detection process, the linkage component 22 and the conveying component 23 are used to convey the PCB board, and during the conveying, the PCB board is turned over by the driving component 21;

[0056] The pusher assembly 32 is used to push up the PCB boards that do not meet the inspection standards, and collect them through the collection assembly 33.

[0057] In this embodiment, before the PCB is discharged, the moving part of the main component 10 will run to adjust the main component 10, and the spacing between the linkage component 22 and the collection component 33 to adjust the internal material passing space to cope with PCB boards of different sizes. Then the PCB board enters the main component 10 and is tested from the front by the detection part on the left side of the detection component 31. If the test fails, the blocking part of the collection component 33 will drop, and the PCB board will be directly transported to the blocking part without turning over, and then pushed into the collection component 33 by the pushing component 32 for collection. If the front test passes, the conveying component 23 will transport the PCB board to the middle of the driving component 21 and the linkage component 22, and the driving component 21 drives the PCB board to turn over and continue to transport it for back detection. The back detection is completed by the detection part on the right side of the detection component 31. If the back detection fails, the PCB board will repeat the above actions and finally be pushed into the collection component 33. If the back detection passes, the PCB board will be directly discharged.

[0058] Next, please refer to Figure 1-Figure 3 The main component 10 includes a body 11, a movable frame 12 is slidably connected to the rear side of the body 11, two sets of hydraulic rods 13 are fixedly connected to the bottom of the body 11, and the rear ends of the hydraulic rods 13 are fixedly connected to the bottom of the movable frame 12. An operating table 14 is electrically connected to the top of the front of the body 11, and a feed port 15 is opened on the left side of the body 11, and a feed belt 16 is provided in the inner cavity of the feed port 15.

[0059] It should be noted that a conical inlet is provided in the feed port 15, so that the offset PCB board can be guided by the conical inlet and moved to the middle position, so as to facilitate subsequent operations;

[0060] The feed belts 16 are driven by an external motor (not shown in the figure). This part is a common structure in the prior art and will not be described in detail here.

[0061] In this embodiment, before the PCB board is discharged, the mobile frame 12 is adjusted accordingly according to the size of the PCB board to control the size of the material transfer space inside the turning assembly 20 and the receiving assembly 30, so as to ensure that PCB boards of different models can move smoothly inside the main assembly 10. The adjustment of the mobile frame 12 can be achieved by the hydraulic rod 13, and the hydraulic rod 13 can accurately adjust the position of the mobile frame 12 under the control of the operating table 14.

[0062] Next, please refer to Figure 3-Figure 8 The driving assembly 21 includes a rotating frame 211 rotatably connected to the top of the front face of the machine body 11, a first motor 212 is fixedly connected to the front face of the machine body 11, an output shaft of the first motor 212 is fixedly connected to the front face of the rotating frame 211, an outer ring of the rotating frame 211 located in the inner cavity of the machine body 11 is fixedly connected to a positioning lamp 213, an electric control ring 214 is fixedly connected to the inner cavity of the machine body 11, and an inner ring of the electric control ring 214 is electrically connected to a receiving plate 215;

[0063] The linkage assembly 22 includes a linkage frame 221 rotatably connected to the top of the mobile frame 12, and linkage rods 222 are fixedly connected to the upper and lower sides of the rear side of the rotating frame 211, and the linkage rods 222 are slidably connected to the upper and lower sides of the linkage frame 221. The tops of the rotating frame 211 and the linkage frame 221 are fixedly connected to the first electric push rod 223, and the bottoms of the first electric push rod 223 are fixedly connected to the clamping plate 224;

[0064] The conveying assembly 23 includes a second motor 231 fixedly connected to the top of the rotating frame 211, a first gear 232 is fixedly connected to the output shaft of the second motor 231, an upper gear rod 233 is rotatably connected to the top right side of the rotating frame 211, an upper chain 234 is meshed with the outer ring of the first gear 232, the bottom of the upper chain 234 is meshed with the front outer ring of the upper gear rod 233, a second gear 235 is fixedly connected to the front top of the upper gear rod 233, a middle gear rod 236 is rotatably connected to the middle part of the front of the rotating frame 211, and the tooth groove of the middle gear rod 236 The lower gear rod 237 is partially meshed with the outer ring of the second gear 235, and the right bottom of the rotating frame 211 is rotatably connected to the lower gear rod 237. The front outer ring of the lower gear rod 237 is meshed with the lower chain 238. The top of the lower chain 238 is meshed with the outer ring of the middle gear rod 236. The right end outer rings of the upper gear rod 233 and the lower gear rod 237 are both slidably connected to the linkage wheel 239. The linkage wheel 239 is rotatably connected to the inner cavity of the linkage frame 221. The outer rings of the two sets of linkage wheels 239, as well as the outer rings of the upper gear rod 233 and the lower gear rod 237 are all rollingly connected to the belt 2310.

[0065] There are two groups of conveying components 23, which are symmetrically distributed on the left and right sides of the rotating frame 211 and the linkage frame 221, so that after the device is turned over, the next group of PCB boards can be turned over directly without resetting and then operating, thereby improving efficiency.

[0066] It should be noted that both the rotating frame 211 and the linkage frame 221 are powered by contact-type power supply equipment, in order to supply energy to the electrical components on the rotating frame 211 and the linkage frame 221;

[0067] The bottom of the clamping plate 224 is provided with a soft rubber material to prevent the PCB from being seriously damaged during clamping;

[0068] The rear ends of the upper gear rod 233 and the lower gear rod 237 are both long rods with hexagonal structures, so that the linkage wheel 239 can slide on the outer rings of the upper gear rod 233 and the lower gear rod 237 and can also be driven to rotate thereby.

[0069] In this embodiment, after the PCB board enters between the rotating frame 211 and the linkage frame 221, the second motor 231 will start, 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 the upper gear rod 233 and the lower gear rod 237 in the running state will 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 to realize the transportation of the PCB board. When the PCB board reaches the middle of the rotating frame 211, the first electric push rod 223 will push the clamping plate 224 to clamp the PCB board to ensure that it remains stable during the flipping process. The flipping action is coordinated by the linkage rod 222. When the first motor 212 drives the rotating frame 211 to rotate, it will drive the linkage frame 221 to rotate together through the linkage rod 222, and flip the clamping plate 224 together with the PCB board to a predetermined angle. During the flipping process, the positioning light 213 will illuminate the receiving plate 215 of the inner circle of the electric control ring 214. Only when the specified angle is reached will the first motor 212 stop running, thereby obtaining a precise flipping angle. After the flipping is completed, the clamping plate 224 is released, and the PCB board continues to be transported to the right detection part of the detection component 31 for back detection.

[0070] Next, please refer to Figure 9-13 The detection component 31 includes a visual observation instrument 311 fixedly connected to the left and right sides of the top of the body 11, and a discharge belt 312 is provided in the right inner cavity of the body 11;

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

[0072] The collecting assembly 33 includes a collecting rack 331 fixedly connected to the right side of the top of the body 11 and the movable rack 12, a support plate 332 is rotatably connected to the bottom of the inner cavity of the collecting rack 331, a third electric push rod 333 is fixedly connected to the collecting rack 331 located on the body 11, and a baffle 334 is fixedly connected to the bottom output end of the third electric push rod 333.

[0073] It should be noted that a torsion spring (not shown in the figure) is provided in the internal rotation axis area of ​​the support plate 332, so as to keep the end of the support plate 332 facing outwards at all times in a normal state;

[0074] A plurality of cameras are arranged at the bottom of the visual observation instrument 311, and the number of cameras to be opened at the bottom of the visual observation instrument 311 is selected according to the moving length of the mobile frame 12, so as to cope with PCB boards of different sizes, and reduce the number of cameras to be opened when the PCB board size is small, thereby reducing energy consumption;

[0075] The tops of the first lifting frame 323 and the second lifting frame 324 are both provided with anti-slip plates, and the anti-slip plates cannot contact the pallet 332, so that after the PCB board is raised to collect the pallet 332 and continue to be pushed up for collection, the two sets of lifting frames will not be blocked by the reset pallet 332 when they are subsequently lowered;

[0076] The operation of the third electric push rod 333 is controlled by the visual observation instrument 311. The third electric push rod 333 will only descend when a substandard PCB board is observed.

[0077] In this embodiment, before the PCB board is turned over, the visual observation instrument 311 on the left side will be used to observe the front side. If it does not meet the standard, the third electric push rod 333 will push the baffle 334 down. At this time, the PCB board that does not meet the standard will not be turned over, but will be 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, and lift the PCB board. In the process of the PCB board rising, the support plate 332 will be pushed to be folded up so that the PCB board can pass smoothly. Then the PCB board will continue to rise. When the PCB board is pushed into the collection rack 331, the support plate 332 will automatically reset through the action of the torsion spring, and then the two sets of lifting frames will descend, and the PCB board will be placed steadily on the support plate 332. If the PCB board is qualified in the front detection, the back detection will be carried out after the material is turned over. If the back is unqualified, the above action will be repeated to collect the PCB board. Qualified PCB boards are directly discharged through the discharge belt 312, thereby realizing 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 meet the inspection requirements of different types of PCB boards. The anti-slip plate design of the lifting plate 322 and the two sets of lifting frames ensures the stable clamping and transmission of PCB boards in different working environments, reducing the risk of damage caused by sliding.

[0079] Example 2

[0080] This embodiment provides a PCB board receiving method, which is used for receiving PCB boards by any of the above-mentioned PCB manufacturing flip receiving devices, including:

[0081] S1: Before the material receiving inspection, the hydraulic rod 13 drives the mobile frame 12 to move, adjusts the gap with the machine body 11, and feeds the PCB board into the feed port 15 through the feed belt 16, and performs an inspection through the visual observation instrument 311 on the left side;

[0082] S2: When the PCB board that fails to meet the standard is detected, the third electric push rod 333 pushes the baffle 334 to descend, and the PCB board that fails to meet the standard is directly transported to the left side of the baffle 334 through the belt 2310 and the discharge belt 312, and is pushed up by the second lifting frame 324 and the first lifting frame 323, and is stuck on the top of the support plate 332;

[0083] S3: The PCB board that meets the standards once will be sent to the belt 2310 and fixed by the clamping plate 224, and then turned over by the driving component 21, and then the turned PCB board will be sent to the discharge belt 312, and the visual observation instrument 311 on the right side will be used for secondary inspection;

[0084] S4: The PCB boards that meet the secondary inspection standards are directly discharged through the discharge belt 312, while the PCB boards that do not meet the standards are sent to the top of the pallet 332 for collection through the steps in S2.

[0085] In this embodiment, in S1, when the PCB board enters the feed port 15, it will be automatically aligned by the inclined surface of the feed port 15;

[0086] In S3, when flipping the PCB board, you can choose to clamp the PCB board first and then flip it, or you can lower the clamp 224 in advance and use the clamp 224 to block the moving path of the PCB board, so that the PCB board enters the range of the belt 2310 and then flips upward directly, so that the PCB board falls directly on the left side of the clamp 224 during the flipping process, and is directly located on the right side of the clamp 224 after flipping, so as to achieve faster material flipping.

[0087] The working principle of the present invention is as follows: before the PCB board is discharged, the mobile frame 12 will be adjusted accordingly according to the size of the PCB board to control the size of the material transfer space inside the material turning component 20 and the material receiving component 30. Before the PCB board is turned over, it will be observed from the front through the visual observation instrument 311 on the left. If it does not meet the standard, the third electric push rod 333 will push the baffle 334 down. At this time, the PCB board that does not meet the standard will not be turned over, but will be 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 up, and then push the first lifting frame 323 and the second lifting frame 324 up, lift the PCB board, and push it to the top of the support plate 332 for collection. If the PCB board is qualified in the front detection, it will be inspected on the back after turning over. If the back is unqualified, the above action will be repeated to collect the PCB board. The qualified PCB board is directly discharged through the discharge belt 312. During the flipping process of the PCB board, the PCB board will enter between the rotating frame 211 and the linkage frame 221, and then the second motor 231 will start, 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 at the same time drives the linkage wheel 239 to rotate, and then drives the front and rear belts 2310 to run together to realize the transportation of the PCB board. When the PCB board reaches the middle of the rotating frame 211, the first electric push rod 223 will push the clamping plate 224 to clamp the PCB board. 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, and flips the clamping plate 224 together with the PCB board to a predetermined angle. After the flipping is completed, the clamping plate 224 is released, and the PCB board continues to be transported to the right detection part of the detection component 31 for back detection, thereby realizing the flipping and receiving operation of the PCB board.
