Description

Technical Field

[0001] This invention relates to the field of circuit board stacking technology, and in particular discloses a multi-station receiving and stacking device and stacking method. Background Technology

[0002] With the continuous development and progress of society, industrial equipment is also constantly being updated. In modern society, the production efficiency and pass rate of products are very important parts of enterprise competition. By timely sorting out qualified and unqualified products, it is possible to prevent them from flowing out or affecting subsequent production and processing.

[0003] During the circuit board manufacturing process, in order to facilitate the transportation of large quantities of circuit boards at one time, the manufactured circuit boards are stacked in multiple layers, and spacers are placed between the stacked circuit boards to prevent scratches between the upper and lower circuit boards. After protection, they are transported. However, some of the manufactured circuit boards may have defects. Therefore, when using them, the incoming circuit boards are inspected and analyzed again, and those that do not meet the usage requirements are selected.

[0004] Currently, circuit board testing equipment on the market involves manual loading of circuit boards, followed by testing and analysis inside the equipment. Defective products are then set aside, while qualified products are placed together. However, during the stacking process, manual placement of spacers is required on the circuit boards, and the stacked circuit boards are then transported away manually. This results in cumbersome operation and low automation of existing circuit board testing equipment, requiring manual intervention, leading to low production efficiency. Furthermore, failure to promptly remove spacers can damage the circuit boards.

[0005] Therefore, a new technical solution is needed to address the above problems. Summary of the Invention

[0017] As a preferred embodiment, a transfer platform is also provided between the conveying platform and the unloading turntable. The lower end of the transfer platform is provided with a transfer slide rail for driving its movement. The transfer slide rail is located between the conveying platform and the unloading turntable and enables the transfer platform to transport the qualified circuit boards to the unloading turntable for stacking and temporary storage.

[0018] As a preferred embodiment, it also includes a paper feeding mechanism located on one side of the conveying platform. The number of transfer platforms is set to two sets: one set of transfer platforms is used to transport circuit boards that have passed the test by the testing mechanism, and the other set of transfer platforms is used to transport the spacer paper placed between the stacked circuit boards.

[0019] The paper feeding mechanism includes a paper feeding platform for storing paper dividers and a baffle.

[0021] As a preferred embodiment, the number of the feeding trays is set to several, and the several feeding trays are circumferentially distributed on the edge of the feeding turntable. The feeding trays can carry circuit boards of different sizes and pack them up.

[0022] One side of the feeding turntable is also provided with a labeling mechanism for labeling stacked circuit boards and a feeding port for unloading packaged circuit boards.

[0023] A multi-station material receiving and stacking method includes the following steps:

[0024] S1: Place the incoming circuit boards into the loading hopper, then use the loading adsorption assembly to adsorb the circuit boards to be inspected and place them onto the conveyor platform, and then use the loading adsorption assembly to place the circuit boards to be inspected onto the conveyor platform.

[0025] The paper is placed between stacked circuit boards and transferred to the receiving compartment via adsorption.

[0026] S2: The conveyor platform transports the circuit board to be tested forward. At this time, the vision inspection mechanism located above the conveyor platform performs a preliminary dimensional inspection of the circuit board. If it meets the preliminary inspection standards, it will proceed to the next step of testing and analysis; if it does not meet the preliminary inspection standards, it will be judged as unqualified.

[0030] S4: When placing defective circuit boards into the defective product collection rack, a separator paper will be placed on top of the defective circuit board by the first suction robot to prevent the two circuit boards from being separated.

[0031] The board came into contact with something, causing further damage;

[0032] S5: After testing and analysis by the testing agency, it can be determined whether the circuit board meets the usage requirements. If the circuit board meets the usage requirements, it will be picked up by the first adsorption robot and placed on the transfer platform for transportation. If the circuit board does not meet the testing requirements, the first adsorption robot will pick up and transfer it to the defective product collection rack and place a layer of paper on top.

Then, the circuit board is detected and analyzed by the detection device, and unqualified circuit boards are selected. The circuit board is stored on one side by the robotic arm, and the robotic arm adsorbs a partition paper and places it on the unqualified circuit board for protection.

[0041] Qualified circuit boards are placed on a transfer platform by a robotic arm and then transported to the next stage.

Detailed Implementation

[0051] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0052] like Figure 1-6 As shown, a multi-station material receiving and sorting device includes a frame 100. The frame 100 is equipped with a feeding device 200, a transfer mechanism 300, a detection device 400, a conveying platform 500, and a unloading device 600. The conveying platform 500 is positioned between the feeding device 200 and the unloading device 600, and the transfer mechanism 300 is positioned above the conveying platform 500, thereby realizing an automated process of feeding, detection, unloading, and packaging.

[0053] In this embodiment, the feeding device 200 includes a feeding bin 210 for placing incoming circuit boards, a receiving bin 220, and a feeding adsorption assembly 230. The conveying platform 500 is set on one side of the feeding bin 210 and is used to carry the incoming circuit boards forward.

[0054] The detection device 400 is located on the side of the transfer platform 500 to analyze the data information of the test circuit board and transmit the measured data to the central control system for analysis and verification. Then, the central control system issues corresponding control commands to transfer the circuit board.

[0055] The feeding device 600 includes a rotating feeding turntable 610 and a feeding tray 620 for placing circuit boards on the feeding turntable 610. The feeding tray 620 can hold circuit boards of different sizes and specifications, has good adaptability, maximizes the detection effect, and does not require multiple replacements of the feeding tray 620, thus improving the efficiency of detection and stacking.

[0056] In this embodiment, by placing the receiving hopper 220 on the other side of the feeding hopper 210, and providing a lifting platform for lifting incoming circuit boards inside the feeding hopper 210, and horizontally placing the feeding adsorption component 230 above the feeding hopper 210, in use, the entire stack of incoming circuit boards is placed into the feeding hopper 210, and the circuit boards are adsorbed by the adsorption effect of the feeding adsorption component 230, then transferred and placed on the conveyor platform 500, and then the partition paper is adsorbed by the feeding adsorption component 230 and placed into the receiving hopper 220, thereby completing the circuit board feeding process and realizing the automated feeding and partition paper collection process, without the need for manual collection of partition paper.

[0057] Specifically, the feeding and adsorption assembly 230 includes a fixed frame 231, a transverse shift seat 232, and a feeding and adsorption hand 233. The fixed frame 231 is horizontally installed inside the frame 100 and positioned above the feeding bin 210 and the conveying platform 500. The transverse shift seat 232 is placed on the fixed frame 231, and the feeding and adsorption hand 233 is fixed to the transverse shift seat 232 and moves left and right with the transverse shift seat 232. A feeding control mechanism is also provided between the transverse shift seat 232 and the feeding and adsorption hand 233. The lifting drag chain 234 for the up-and-down movement of the suction hand 233, and the horizontal drag chain 235 for controlling the left-and-right movement of the horizontal transfer seat 232 are also provided at the upper end of the fixed frame 231. The movement and suction of the feeding suction hand 233 are realized through the cooperation of the lifting drag chain 234 and the horizontal drag chain 235. Two feeding suction hands 233 are used, and the two feeding suction hands 233 work at the same time. One is used to suction the circuit board and the other is used to suction the separator paper, thereby improving the efficiency of circuit board feeding.

[0058] Furthermore, a feeding bin 210 and a receiving bin 220 are provided on both sides of the conveyor platform 500, which can realize staggered feeding on both sides and improve the feeding speed of circuit boards.

[0059] In this embodiment, the detection device 400 includes a visual inspection mechanism 410 for analyzing the size and position of the circuit board and a testing mechanism 420 for testing the performance of the circuit board. By placing the visual inspection mechanism 410 above the conveying platform 500 and fixing it inside the frame 100, the CCD camera captures the position information of the circuit board image transported by the conveying platform 500 and uploads it to the central control system for analysis to determine whether the current circuit board meets the detection requirements.

[0060] Specifically, the testing mechanism 420 is set on one side of the conveying platform 500. The circuit boards that have passed the measurement on the conveying platform 500 are transferred by the transfer mechanism 300 and placed into the testing mechanism 420 for testing and code reading. This further detects and identifies whether the circuit boards meet the usage requirements, enabling the rapid selection of qualified circuit boards and effectively preventing unqualified circuit boards from being released.

[0061] In practical use, the inspection device 400 also includes a defective product collection rack 430. By placing the defective product collection rack 430 on the other side of the conveyor platform 500, it is convenient to collect and store circuit boards that fail visual inspection and testing. When the circuit boards transported by the conveyor platform 500 are quickly inspected by the visual inspection mechanism 410 and tested by the testing mechanism 420, and are determined to be unqualified, the unqualified circuit boards will be selected and placed on the defective product collection rack 430 on one side, so that they can be reprocessed later, thereby improving the efficiency of use and reducing the waste of resources.

[0062] In this embodiment, a transfer platform 700 is also provided between the conveying platform 500 and the unloading turntable 610. A transfer slide rail 710 for driving the transfer platform 700 to move is provided at the lower end of the transfer platform. The transfer slide rail 710 is provided between the conveying platform 500 and the unloading turntable 610 so that the transfer platform 700 can transport the qualified circuit boards to the unloading turntable 610 for stacking and temporary storage.

[0063] In actual use, it also includes a paper feeding mechanism 800, which is set on one side of the conveying platform 500. The number of transfer platforms 700 used is set to two sets. One set of transfer platforms 700 is used to transport circuit boards that have passed the test by the testing mechanism 420. One end of the other set of transfer platforms 700 is located at the outer end of the paper feeding mechanism 800 to transport the partition paper coming out of the paper feeding mechanism 800 and transfer the partition paper to be placed between the stacked circuit boards.

[0064] Specifically, the paper feeding mechanism 800 includes a paper feeding platform 810 for storing paper dividers and a baffle 820. By tilting the baffle 820 onto the paper feeding platform 810 and having one side of the baffle 820 abut against the paper divider, excessive paper dividers are prevented from sliding forward at once. A certain distance is maintained between the lower end of the baffle 820 and the paper feeding platform 810 to facilitate the extension of the paper dividers. Furthermore, a paper output roller assembly 830 is provided on the paper feeding platform 810 and is located on the other side of the baffle 820. The paper output roller assembly 830 is used to rotate and transfer the extended paper dividers to the transfer platform 700, thereby realizing the automatic feeding and transfer of paper dividers.

[0065] In this embodiment, the transfer mechanism 300 includes a first adsorption robot 310 and a second adsorption robot 320 that can rotate arbitrarily. The first adsorption robot 310 is positioned above the detection device 400 to adsorb and transfer the circuit boards transported by the conveying platform 500 to the detection device 400 for detection and analysis. Circuit boards that meet the requirements are selected and placed on the transfer platform 700 for continued transport, while circuit boards that do not meet the requirements are placed on the defective product collection rack 430 for subsequent reprocessing. The second adsorption robot 320 is positioned above the unloading device 600 to transfer the qualified circuit boards from the transfer platform 700 to the unloading turntable 610 for placement and packaging.

[0066] Specifically, both the first adsorption robot 310 and the second adsorption robot 320 are equipped with multiple movable joint components, and a suction nozzle for adsorbing circuit boards is provided at the lower end of the joint components. A fixing seat 330 is provided at the upper end of them to install the transfer mechanism 300 in the frame 100, so that the first adsorption robot 310 or the second adsorption robot 320 can rotate within a certain range. Through multi-angle rotation and the combination of flexible joint components with multiple degrees of freedom, circuit boards can be adsorbed and moved from different ranges, increasing the scope of use.

[0067] Specifically, the number of unloading trays 620 is set to several. These unloading trays 620 are distributed circumferentially around the edge of the unloading turntable 610. The unloading trays 620 can carry circuit boards of different sizes and can also be stacked according to different models and sizes of circuit boards, which can play a role in quick classification, maximize the efficiency of use, avoid downtime to replace trays, improve work efficiency, and pack and organize the stacked circuit boards.

[0068] Furthermore, a labeling mechanism 630 for labeling stacked circuit boards and a feeding port 640 for unloading packaged circuit boards are provided on one side of the unloading turntable 610. A rotary motor 650 for driving the unloading turntable 610 to rotate is also provided at the lower end of the unloading turntable 610. The unloading turntable 610 rotates the stacked circuit boards to the labeling mechanism 630, prints out the data information through the labeling mechanism 630 and affixes it to the outer end of the circuit board for identification, and then unloads and transfers the packaged circuit boards through the feeding port 640, thereby completing the classification and unloading of incoming circuit boards, detecting and classifying qualified and unqualified circuit boards, and packaging qualified circuit boards.

[0069] Specifically, the first adsorption robot 310, the second adsorption robot 320, and the feeding adsorption robot 233 used in this equipment are all externally connected to control cylinders to control the air pressure state of their adsorption circuit boards, thereby realizing the adsorption and movement.

[0070] A multi-station material receiving and stacking method includes the following steps:

[0071] S1: The incoming circuit board is placed in the feeding bin 210, and then the feeding adsorption component 230 adsorbs and places the circuit board to be tested onto the conveying platform 500. Then the feeding adsorption component 230 adsorbs and transfers the paper spacer placed between the stacked circuit boards to the receiving bin 220.

[0072] S2: The conveyor platform 500 transports the circuit board to be tested forward. At this time, the vision inspection mechanism 410 located above the conveyor platform 500 performs a preliminary dimensional inspection of the circuit board. If it meets the preliminary inspection standards, the next step of testing and analysis will proceed; if it does not meet the preliminary inspection standards, it will be judged as...

[0073] These are substandard products.

[0074] S3: The first adsorption robot 310 transfers the circuit boards that have passed the initial inspection to the testing mechanism 420 for re-inspection; the first adsorption robot 310 also transfers the circuit boards that fail the initial inspection to the defective product collection area located on the side.

[0075] Stacking was carried out at position 430;

[0076] S4: When placing the defective circuit board into the defective product collection rack 430, the first suction robot arm 310 will also suction a spacer paper and place it on the defective circuit board to prevent the two sheets from being placed on top and bottom.

[0077] The circuit board was touched, causing further damage;

[0078] S5: After testing and analysis by the testing agency 420, it can be determined whether the circuit board meets the usage requirements. When the circuit board meets the usage requirements, it is picked up and placed on the transfer platform 700 by the first adsorption robot 310 for transportation; when the circuit board does not meet the testing requirements, the first adsorption robot 310 will pick up and transfer it to the defective product collection rack 430 for placement, and then...

[0079] Place a layer of paper at the end;

[0080] S6: Circuit boards that meet the testing requirements will be transported to the rear end via the transfer platform 700. Then, the second suction robot 320 will pick up the circuit boards and place them in the unloading tray 620 of the unloading turntable 610, using a layer of circuit boards and a layer of paper separator for processing.

[0081] Place them in rows to prevent stacked circuit boards from touching and being damaged.

[0082] S7: When the first unloading tray 620 is full, the unloading turntable 610 will rotate to allow the second empty unloading tray 620 to continue stacking circuit boards, and so on in a continuous cycle.

[0083] S8: After a sufficient number of neatly stacked circuit boards are placed on the unloading tray 620, they will be packaged and labeled on the outside of the circuit boards by the labeling mechanism 630.

[0084] S9: The labeled circuit board is unloaded through the unloading port 640 for storage or transfer to the next processing station.

[0085] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
