Description

Technical Field

[0001] The utility model relates to the technical field of PCB automated production and processing, in particular to an automatic tray packaging machine. 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

[0009] 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.

[0010] 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.

[0014] Furthermore, the processing equipment also includes a humidity card automatic placement mechanism, and the humidity card automatic placement mechanism is arranged beside the feeding line.

[0015] By adopting the above solution, the utility model forms a return circulation line for the fixture by setting the lifting and swinging plate mechanism and the automatic return plate mechanism at both ends of the double-layer transport line. This setting has the following advantages:

[0016] 1. Reduce operational errors during manual plating:

[0017] 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.

[0018] 2. Significantly improve packaging efficiency:

[0019] 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.

[0020] 3. Improve product safety:

[0021] 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.

[0022] 4. Error proofing involves:

[0023] 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.

[0024] 5. Reduce packaging costs and risks:

[0025] 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.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See also Figures 1 to 3 The present invention provides an automatic tray packaging machine, comprising: a lifting tray mechanism 2 arranged in the OK material table area of ​​a sorting and counting machine 1, a double-layer transport line 3 arranged at the rear end of the lifting tray mechanism 2, and an automatic tray return mechanism 4 arranged at the rear end of the double-layer transport line 3, the double-layer transport line 3 comprising an upper transport line 31 and a lower tray return line 32, the lifting and lowering limit positions of the lifting tray mechanism 2 and the automatic tray return mechanism 4 respectively correspond to the height positions of the upper transport line 31 and the lower tray return line 32 of the double-layer transport line 3 and the transport surface is flush, a processing area 30 is provided in the middle section of the upper transport line 31 of the double-layer transport line 3, a processing equipment 5 is provided beside the processing area 30, and the processing equipment 5 performs processing operations on the upper transport line 31.

[0031] During operation, the sorting and counting machine 1 inspects and sorts PCB boards processed in upstream equipment, then places qualified products into a jig on a lifting and swinging plate mechanism 2 located in the OK material table area. When the jig is full of PCB products, the lifting and swinging plate mechanism 2 transports the jig containing PCB boards to a double-layer conveyor line 3, which then transports the jig forward. When the upper conveyor line 31 of the double-layer conveyor line 3 lifts the jig filled with PCB products and transports it to the processing area 30, the PCB boards on the jig are processed by the processing equipment 5. The finished jig is then transported to the automatic return plate mechanism 4, where the processed PCB boards are picked up manually or by a robot and moved out of the material. After all PCBs on the jig are discharged, the automatic return mechanism 4 moves the empty jig downward, aligning it with the lower return line 32. The empty jig is then transferred to the lower return line 32, where it is then transported toward the lifting and swinging mechanism 2. At this point, the lifting and swinging mechanism 2 descends to the height corresponding to the lower return line 32, moving the empty jig onto the lifting and swinging mechanism 2. The lifting and swinging mechanism 2 then lifts the empty jig upward, allowing the sorting and counting machine 1 to transfer the next batch of qualified PCBs to the empty jig for placement on the swinging mechanism. This cycle repeats.

[0032] In some embodiments, see Figure 3 The sorting and counting machine 1 is provided with a material-grabbing robot 11 corresponding to the lifting and swinging plate mechanism 2. The material-grabbing robot 11 includes: a multi-axis moving mechanism 111 arranged next to the lifting and swinging plate mechanism 2, and a gripper unit 112 arranged on the output end of the multi-axis moving mechanism 111. The multi-axis moving mechanism 111 drives the gripper unit 112 to move. The gripper unit 112 adopts a plurality of pneumatic clamps or a plurality of vacuum suction cups. The multi-axis moving mechanism 111 drives the gripper unit 112 to move to the top of the lifting and swinging plate mechanism 2 for sorting and placement.

[0033] By setting a material picking robot 11 at the sorting and counting machine 1, the gripper unit 112 is moved to the PCB board product to be sorted through the multi-axis moving mechanism 111. When the current PCB board product is identified as a qualified product, the PCB board is picked up by the gripper unit 112, and the gripper unit 112 is moved above the lifting and swinging plate mechanism 2 through the multi-axis moving mechanism 111, and the picked PCB board is placed at the corresponding placement position on the jig for sorting and discharging.

[0034] 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 tilting machine, where it releases the PCB from the jig, completing the picking, moving, and placement of the PCB.

[0035] 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.

[0036] 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 31. 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 material table area of ​​the sorting and counting machine 1.

[0037] 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.

[0038] When the number of PCBs placed in the jigs on the lifting and swinging plate mechanism 2 reaches the upper limit, the conveyor line 27 is automatically raised and lowered, transferring the fully loaded jigs to the upper conveyor line 31 of the double-layer conveyor line 3 for subsequent feeding and processing of the PCBs. The swinging plate lifting 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 lifting and conveying line 27 to a height level with the lower return line 32. The lower return line 32 then moves the empty jigs onto the lifting and conveying line 27. The swinging plate lifting 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 lifting and conveying line 27 to a height level with the upper conveyor line 31, facilitating the sorting and placement of the next group of PCBs.

[0039] In some optional embodiments, a plurality of guide posts 28 are provided on the sides of the lead screw 24 and are parallel to the lead screw 24. The guide posts 28 pass through the lifting frame 26. As the lifting frame 26 is lifted and lowered along with the lead screw slider 25, the guide posts 28 provide guidance to the lifting frame 26, directing the movement direction of the lifting frame 26 and preventing deviation. Corresponding photoelectric sensors 29 are provided on the guide posts 28, corresponding to the upper and lower limit positions of the lifting and lowering movement of the lifting frame 26. When the lifting frame 26 moves to the upper or lower limit position, the photoelectric sensors 29 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, stopping the lifting frame 26 at the corresponding height position, thereby allowing the lifting transport line 27 to remain at a height position flush with the upper transport line 31 or the lower return line 32.

[0040] In some embodiments, see Figure 2 The automatic return mechanism 4 includes: a return frame 41 connected to the double-layer transport line 3, a return lift platform 42 that moves up and down in the middle of the return frame 41, a return lift motor 43 arranged at the bottom of the return lift platform 42, an output gear 44 connected to the output end of the return lift motor 43, and a rack 45 arranged on the return frame 41, the output gear 44 and the rack 45 are engaged with each other, and a return conveyor line 46 is provided on the return lift platform 42.

[0041] When a fully loaded jig is moved to the automatic return tray mechanism 4, an external robot removes the PCB board from the jig. Alternatively, on the double-layer conveyor line 3, an external robot removes the PCB board from the jig, and then the empty jig is moved to the automatic return tray mechanism 4. The return tray lift motor 43 is then activated, causing the output gear 44 to begin rotating. This, through the meshing of the output gear 44 and the rack 45, lowers the return tray conveyor line 46 on the return tray lift platform 42 to a height level with the lower return tray line 32. The return tray conveyor line 46 is then activated, and the empty jig is moved to the lower return tray line 32. The return tray lift motor 43 is then reversed, causing the output gear 44 to rotate in the opposite direction. This, through the meshing of the output gear 44 and the rack 45, raises the return tray conveyor line 46 on the return tray lift platform 42 to a height level with the upper conveyor line 31.

[0042] In some embodiments, the processing equipment 5 includes a close-fitting packaging mechanism, which includes a feed line 51, a heating zone 52, and a discharge line 53, which are arranged adjacent to the double-layer conveyor line 3. The feed line 51, heating zone 52, and discharge line 53 are arranged sequentially along the conveying direction of the upper conveyor line 31. The feed line 51 delivers the materials required for close-fitting packaging to the jig, where a packaging film is applied to the PCB. The packaging film is then heated in the heating zone 52, causing it to shrink and tightly wrap around the PCB.

[0043] In some embodiments, the processing equipment 5 further includes an automatic desiccant placement mechanism, which is disposed adjacent to the feed line 51. Prior to close-fitting packaging, the automatic desiccant placement mechanism places the desiccant on or adjacent to the PCB on the jig. After close-fitting packaging, the desiccant and the PCB are encased in the packaging film. The desiccant absorbs moisture from the packaging film, preventing moisture from adhering to the PCB and potentially damaging the PCB surface or circuit components thereon.

[0044] In some embodiments, the processing equipment 5 further includes an automatic humidity card placement mechanism, which is located next to the feed line 51. Before close-fitting packaging, the humidity card placement mechanism places the humidity card on or next to the PCB on the jig. After close-fitting packaging, the humidity card and the PCB are wrapped in the packaging film together. The humidity card monitors the humidity within the packaging film, preventing damage to the PCB surface or circuit components on the PCB due to excess moisture in the packaging film.

[0045] In summary, the present invention forms a fixture recirculation line by installing a lifting and swinging plate mechanism and an automatic return plate mechanism at both ends of the double-layer transport line, avoiding the overall low work efficiency caused by manual handling and meeting the requirements of large-scale production and processing. Furthermore, by providing a work area on the double-layer transport line, PCB boards can be processed through corresponding close packaging and other processing steps while being transported, effectively improving overall processing efficiency and preventing excessive picking and moving that could damage the packaging film or scratch the circuit board surface, thereby ensuring product yield.

[0046] 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.
