Description

Technical Field

[0001] The utility model relates to the technical field of PCB automated production and processing, in particular to an automatic plate-swinging mechanism. Background Art

[0002] There are currently two solutions on the market for connecting sorting points to close packaging machines:

[0003] 1. A sorting and counting machine performs sorting and counting, separating qualified (OK) PCBs from defective (NG) PCBs. The qualified PCBs are placed on the OK tray, and the defective PCBs are placed on the NG tray. When the OK tray is full, the tray is lowered to discharge the PCBs. A conveyor section is extended from the OK tray to serve as a temporary storage area for the sorted qualified PCBs. The PCBs sorted by the sorting and counting machine are then manually transferred to the trays of the close-fitting packaging machine for close-fitting packaging. This solution relies on manual handling, which is labor-intensive, increases operator hours, and raises overall production costs. It is also inefficient and difficult to meet the requirements of large-scale production activities.

[0004] 2. The sorting and counting machine performs sorting and counting, separating qualified (OK) PCBs from defective (NG) PCBs. The qualified PCBs are placed on the OK tray, and the defective PCBs are placed on the NG tray. When the OK tray is full, the tray is lowered to discharge the PCBs, and a conveyor section is extended from the OK tray to serve as a temporary storage section for the sorted qualified PCBs. An automatic material picker then transfers the PCBs sorted by the sorting and counting machine to the tray of the close-fitting packaging machine through mechanical means for close-fitting packaging. This solution has a problem: the close-fitting packaging tray requires bubble wrap of the appropriate size to be placed in advance. If the sorted PCBs are transferred to the tray in piles and the suction device is removed, the bubble wrap on the tray can easily be scratched, affecting the packaging quality and even causing scratches on the surface of the PCBs, resulting in a poor appearance.

[0005] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic plate swinging mechanism.

[0007] The technical solution of the present utility model is as follows: an automatic plate swing mechanism is provided, comprising: a sorting and counting machine, a lifting and swinging plate mechanism arranged next to the sorting and counting machine, and a material picking robot arranged next to the sorting and counting machine and the lifting and swinging plate mechanism, wherein the material picking robot moves back and forth above the sorting and counting machine and the lifting and swinging plate mechanism.

[0008] Furthermore, the material-grabbing robot includes: a multi-axis moving mechanism arranged next to the lifting and swinging plate mechanism, and a gripper unit arranged on the output end of the multi-axis moving mechanism. The multi-axis moving mechanism drives the gripper unit to move, and the multi-axis moving mechanism drives the gripper unit to move above the lifting and swinging plate mechanism for sorting and placement.

[0009] Furthermore, the gripper unit adopts a plurality of pneumatic clamps or a plurality of vacuum suction cups.

[0010] Furthermore, a visual recognition module is provided on the output end of the multi-axis moving mechanism, and the multi-axis moving mechanism drives the visual recognition module to move, and the visual recognition module is suspended above the upper transport line.

[0011] Furthermore, the lifting and lowering swing plate mechanism includes: a swing plate fixing seat, a swing plate lifting motor arranged on the swing plate fixing seat, a synchronous pulley transmission mechanism connected to the output end of the swing plate lifting motor, screws arranged on both sides of the swing plate fixing seat, a screw slider sleeved on the screw, a lifting frame connected to the screw sliders on both sides, and a lifting transport line arranged on the lifting frame, the input end of the synchronous pulley transmission mechanism is connected to the output end of the swing plate lifting motor, and the output ends on both sides of the synchronous pulley transmission mechanism are respectively connected to the screws on both sides, and the swing plate lifting motor drives the screws on both sides to rotate through the synchronous pulley transmission mechanism, thereby driving the screw slider to move up and down.

[0012] Furthermore, a plurality of groups of guide posts parallel to the lead screw are provided on the side of the lead screw, and the guide posts pass through the lifting frame.

[0013] Furthermore, the guide column is provided with corresponding photoelectric sensors at the upper limit position and the lower limit position of the lifting frame.

[0014] Using the above solution, the present invention moves the lifting and swinging plate mechanism to the lower limit position before sorting and unloading. The empty jig tray is then moved from the external return line onto the lifting and swinging plate mechanism. The lifting and swinging plate mechanism then rises and rests at the upper limit position. The retrieving robot places the qualified PCB boards it has picked up at the corresponding placement position on the jig tray, thereby calculating the number of qualified PCB boards. After the sorting points are counted, the jig tray is transported out via the lifting and swinging plate mechanism to facilitate sorting and placement of the next group of qualified PCB boards. This arrangement has the following advantages:

[0015] 1. Reduce operational errors during manual plating:

[0016] The fully automated process of sorting and automatic palletizing completely eliminates common errors during manual palletizing, such as mixed PCB materials and incorrect or missing label information. Especially for products requiring high precision, such as new energy vehicle boards, HDI boards, 5G / 6G communication boards, and multi-layer boards, the automatic palletizing system's error-proofing ensures that every board is handled accurately throughout the packaging process, avoiding quality issues caused by manual oversight and ensuring that the products meet the stringent standards of end customers.

[0017] 2. Significantly improve packaging efficiency:

[0018] Automatic palletizing technology not only reduces manual operations but also significantly improves packaging efficiency. Fully automated operations streamline and streamline the PCB sorting, stacking, and packaging processes, reducing friction, scratches, and other issues associated with manual handling and placement. By reducing manual intervention, companies can significantly increase production speed, especially for high-volume, high-standard production. Automatic palletizing systems ensure continuous and efficient production completion, avoiding bottlenecks.

[0019] 3. Improve product safety:

[0020] When handling circuit boards with varying functional characteristics and complexity, intelligent sorting and automated palletizing ensure accurate and uniform packaging for each batch, preventing issues such as PCB damage and oxidation that can occur during manual handling. For boards with extremely high quality requirements, such as those for new energy vehicles or 5G / 6G communications, automated palletizing technology ensures the highest level of protection during the packaging process, guaranteeing product safety and ultimate quality.

[0021] 4. Error proofing involves:

[0022] Automatic palletizing provides error-proofing and foolproofing, ensuring that each PCB is correctly identified and handled during packaging. By automatically reading and verifying the board's unique identification code, the system automatically avoids labeling errors and missing information throughout the packaging process. Even complex, multi-batch, multi-model PCBs can be accurately processed, ensuring each board is correctly sorted and packaged, eliminating the risks associated with manual intervention.

[0023] 5. Reduce packaging costs and risks:

[0024] Automatic palletizing not only reduces reliance on manual operations through fully automated processes, but also significantly reduces the risk of packaging rework and product returns due to human error. By reducing the complexity and labor intensity of manual operations, companies can lower labor costs and mitigate potential economic losses caused by packaging errors. Furthermore, the efficient operation and error-proofing features of automatic palletizing reduce maintenance and machine adjustment time, improve equipment utilization, and ensure stable and efficient operation of the entire production line. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figure 1 The utility model provides an automatic plate swing mechanism, comprising: a sorting and counting machine 1, a lifting and swinging plate mechanism 2 arranged next to the sorting and counting machine 1, and a material picking robot 11 arranged next to the sorting and counting machine 1 and the lifting and swinging plate mechanism 2, and the material picking robot 11 moves back and forth above the sorting and counting machine 1 and the lifting and swinging plate mechanism 2.

[0028] During operation, the sorting and counting machine 1 inspects and sorts PCB boards processed in upstream equipment. The inspected and identified PCB boards are then sorted by the retrieving robot 11. The retrieving robot 11 picks up defective PCB boards and moves them to the NG unloading platform of the sorting and counting machine 1, where they are placed. It also picks up PCB boards that are not defective and moves them above the lifting and swinging mechanism 2. Before sorting and unloading, the lifting and swinging mechanism 2 moves to its lower limit position. An empty jig tray is moved onto the lifting and swinging mechanism 2 from an external return line. The lifting and swinging mechanism 2 then rises and settles at its upper limit position. The retrieving robot 11 places the qualified PCB boards it has picked up in the corresponding placement position on the jig tray, thereby calculating the number of qualified PCB boards. After the sorting and counting process is complete, the lifting and swinging mechanism 2 removes the jig tray to facilitate sorting and placement of the next group of qualified PCB boards.

[0029] In some embodiments, the material retrieving robot 11 includes: a multi-axis mobile mechanism 111 disposed beside the lifting and swinging plate mechanism 2, and a gripper unit 112 disposed at the output end of the multi-axis mobile mechanism 111. The multi-axis mobile mechanism 111 drives the gripper unit 112 to move, and the multi-axis mobile mechanism 111 drives the gripper unit 112 to move above the lifting and swinging plate mechanism 2 for sorting and placement. The gripper unit 112 is moved to the PCB product to be sorted by the multi-axis mobile mechanism 111. When the current PCB product is identified as qualified, the PCB is picked up by the gripper unit 112. The gripper unit 112 is then moved to the top of the lifting and swinging plate mechanism 2 by the multi-axis mobile mechanism 111, and the picked PCB is placed in the corresponding placement position on the jig for sorting and discharge.

[0030] In some embodiments, the gripper unit 112 uses a plurality of pneumatic grippers or a plurality of vacuum suction cups.

[0031] In some optional embodiments, the gripper unit 112 utilizes pneumatic grippers, which are driven by a pneumatic cylinder to expand and clamp, effectively gripping the PCB from both sides, thereby facilitating the picking of the PCB from the sorting and counting machine 1. The multi-axis motion mechanism 111 then drives the gripper unit 112 to move above the lifting and swinging plate mechanism 2, releasing the PCB from the jig, completing the picking, moving, and placement of the PCB.

[0032] In some optional embodiments, the gripper unit 112 uses a vacuum suction cup to create negative pressure on the vacuum cup, thereby sucking the upper surface of the PCB board, thereby picking up the PCB board on the sorting and counting machine 1. The multi-axis movement mechanism 111 then drives the gripper unit 112 to move above the lifting and tilting machine, and releases the PCB board on the fixture, completing the picking, movement, and placement of the PCB board.

[0033] In some embodiments, a visual recognition module 113 is provided at the output end of the multi-axis moving mechanism 111, and the multi-axis moving mechanism 111 drives the visual recognition module 113 to move, and the visual recognition module 113 is suspended above the upper transport line. Before the PCB board is clamped, the visual recognition module 113 captures an image of the PCB board and sends the image information to the control system, thereby identifying and judging the image information to determine whether the PCB board has any defective conditions. PCB board products that are not detected as defective are judged to be qualified products, and the PCB board is moved to the fixture on the lifting and swinging plate mechanism 2 by the material picking robot 11. When a defective condition is detected on the current PCB board, the material picking robot 11 moves the PCB board to the NG unloading table area of ​​the sorting and counting machine 1.

[0034] In some embodiments, the lifting and lowering swing plate mechanism 2 includes: a swing plate fixing seat 21, a swing plate lifting motor 22 arranged on the swing plate fixing seat 21, a synchronous pulley transmission mechanism 23 connected to the output end of the swing plate lifting motor 22, screws 24 arranged on both sides of the swing plate fixing seat 21, a screw slider 25 sleeved on the screw 24, a lifting frame 26 connected to the screw sliders 25 on both sides, and a lifting and lowering transport line 27 arranged on the lifting frame 26. The input end of the synchronous pulley transmission mechanism 23 is connected to the output end of the swing plate lifting motor 22, and the output ends on both sides of the synchronous pulley transmission mechanism 23 are respectively connected to the screws 24 on both sides. The swing plate lifting motor 22 drives the screws 24 on both sides to rotate through the synchronous pulley transmission mechanism 23, thereby driving the screw slider 25 to move up and down.

[0035] When the number of PCBs placed in the jigs on the swing plate mechanism 2 reaches the upper limit, the conveyor line 27 is automatically raised and lowered, unloading the fully loaded jigs for subsequent processing. The swing plate lift motor 22 is then activated, driving the lead screws 24 on both sides via the synchronous pulley transmission mechanism 23 to rotate, causing the lead screw blocks 25 to move downward along the lead screws 24, lowering the conveyor line 27 to a height level with the lower return line. The lower return line then moves the empty jigs onto the conveyor line 27. The swing plate lift motor 22 is then reversed, driving the lead screws 24 on both sides via the synchronous pulley transmission mechanism 23 to rotate, causing the lead screw blocks 25 to move upward along the lead screws 24, raising the conveyor line 27 to a height level with the upper conveyor line, facilitating sorting and placement of the next group of PCBs.

[0036] In some embodiments, several groups of guide columns 28 parallel to the lead screw 24 are provided on the side of the lead screw 24. The guide columns 28 pass through the lifting frame 26. In this way, when the lifting frame 26 is lifted and lowered along with the lead screw slider 25, the guide columns provide guidance to the lifting frame 26, guiding the moving direction of the lifting frame 26 to avoid deviation.

[0037] In some embodiments, the guide column 28 corresponds to the upper limit position and the lower limit position of the lifting frame 26, and is respectively provided with corresponding photoelectric sensors. When the lifting frame 26 moves to the upper limit position or the lower limit position, the photoelectric sensor can send a corresponding detection signal to the control system, thereby sending a corresponding control signal to the swing plate lifting motor 22 through the control system to stop the lifting frame 26 at the corresponding height position, so that the lifting transport line 27 can be maintained at a height position flush with the upper transport line or the lower return line.

[0038] In summary, the present invention involves moving the tilting plate mechanism to its lower limit before sorting and unloading. An empty jig tray is then moved onto the tilting plate mechanism from an external return line. The tilting plate mechanism then rises and settles at its upper limit. A retrieving robot then places the qualified PCBs it has picked up at the corresponding placement position on the jig tray, thereby counting the number of qualified PCBs. After the sorting count is complete, the tilting plate mechanism removes the jig tray, facilitating sorting and placement of the next group of qualified PCBs.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
