[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] When the electronic component receiving trays are moved in and out, a single-station design is usually used. It is necessary to wait for a full tray to be moved out before an empty tray is moved in. This results in a significant waiting time in the electronic component receiving process, affecting the continuity of electronic component receiving, reducing overall production efficiency, increasing production cycle, and making it difficult to meet the needs of large-scale production.

[0018] In view of this, the present invention provides a dual-station staggered TRAY tray loading and unloading module. Through the cooperation of the base, inner support plate, side plate, dual-station moving component and tray loading and unloading component, a dual-station staggered design is adopted. By automating the replacement of the TRAY tray on the top of the carrier, when one carrier is carrying a fully loaded TRAY tray for unloading, the other carrier simultaneously carries an empty TRAY tray to a designated position for loading electronic components. This avoids the waiting time for changing TRAY trays in the traditional single-station design, thereby avoiding interruptions in electronic component receiving, improving the continuity of electronic component receiving and overall production efficiency, helping to shorten the overall production cycle of electronic components, and meeting the needs of large-scale production.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Depend on Figure 1-8 It is known that a double-station staggered TRAY tray loading and unloading module includes a base 1, an inner support plate 2 is fixedly connected inside the base 1, and side plates 3 are fixedly connected at equal intervals to the top of the base 1. The double-station staggered TRAY tray loading and unloading module also includes a double-station moving component 4 and a tray loading and unloading component 5. The double-station moving component 4 is located on the side where the two side plates 3 are close to each other; the tray loading and unloading component 5 is located on the top of the side plates 3. The double-station moving component 4 adopts a double-station staggered design to perform alternating loading and unloading operations on the TRAY tray, and the tray loading and unloading component 5 performs loading or unloading operations on the TRAY tray to the workstation carrier. In the specific implementation process, it is worth noting that the base 1 is used to provide stable support for the entire equipment, ensuring its stability during operation. The inner support plate 2 supports and fixes some components inside the equipment within the base 1. Through the cooperation between the base 1, side plate 3, and dual-station moving assembly 4, a staggered dual-station design is adopted, and the dual-station carriers are independently controlled. When one carrier is unloading a fully loaded tray, the other carrier simultaneously moves an empty tray to a designated position for loading electronic components. This avoids the waiting time for changing trays in traditional single-station designs, thus preventing interruptions in electronic component receiving and improving the continuity of electronic component receiving and overall production efficiency. Through the cooperation between the base 1, side plate 3, dual-station moving assembly 4, and tray loading / unloading assembly 5, the tray loading / unloading assembly 5 uses vacuum suction to pick up and move the tray. By moving the carrier and picking up and moving the tray, the fully loaded tray is moved to the point where it is unloaded. When in position, a full-loaded tray is picked up from the top of the carrier and moved upwards, while an empty tray is picked up from the empty tray stacking position and moved upwards. The unloading carrier moves from the full-loaded tray unloading position to the empty tray loading position. Then, the full-loaded tray is moved downwards for stacking, and the empty tray is moved downwards to the top of the carrier for release. This realizes the automated loading and unloading operation of the trays. Through the cooperation between the base 1, inner support plate 2, side plate 3, dual-station moving assembly 4 and tray loading and unloading assembly 5, a dual-station staggered design is adopted. By automatically changing the trays on the top of the carrier, when one carrier is carrying a full-loaded tray for unloading, another carrier is simultaneously carrying an empty tray to a designated position for loading electronic components. This avoids the waiting time for changing trays in the traditional single-station design, thereby avoiding the interruption of electronic component receiving, improving the continuity of electronic component receiving and overall production efficiency, helping to shorten the overall production cycle of electronic components, and meeting the needs of large-scale production. Furthermore, the dual-station moving assembly 4 includes a synchronous pulley 41, a synchronous belt 42, a servo motor 43, a slide rail 44, a moving carrier 45, a limiting block 46, and a receiving tray 47. Two sets of synchronous pulleys 41 are provided, rotatably connected to the sides of the two side plates 3 that are close to each other. The synchronous belt 42 is engaged with the outer wall of the synchronous pulleys 41. The servo motor 43 is fixedly connected to one end of the outer wall of the side plate 3, and its output end is driven by the synchronous pulleys 41. The slide rail 44 is fixedly connected to the outer wall of the side plate 3, located above and below the synchronous belt 42. Two mobile carriers 45 are provided, distributed on the upper and lower sides of the two side plates 3 that are close to each other, slidably connected to the outer wall of the slide rail 44, and respectively fixedly connected to the synchronous belt 42; the limiting blocks 46 are fixedly connected to both sides of the mobile carriers 45 at equal distances; the receiving tray 47 is connected to the mobile carriers 45 and the limiting blocks 46; wherein, driven by the servo motor 43, the synchronous wheel 41 and the synchronous belt 42 are driven to rotate, so that the two mobile carriers 45 can drive the receiving tray 47 to move in a staggered manner along the slide rail 44; In the specific implementation process, it is worth noting that, through the cooperation between the side plate 3, synchronous pulley 41, synchronous belt 42, servo motor 43, slide rail 44, and moving carrier 45, the two moving carriers 45 are vertically staggered between the two side plates 3 via two sets of slide rails 44. Through the power transmission system composed of the two sets of synchronous pulleys 41, synchronous belt 42, and servo motor 43, the two moving carriers 45 can move independently and precisely without interfering with each other during movement, achieving staggered movement of the two workstations. Through the cooperation between the moving carrier 45, the limiting block 46, and the receiving tray 47, the receiving tray 47 is a TRAY tray with multiple grooves on its top for placing the mounted electronic components. The limiting block 46 on the top of the moving carrier 45 is positioned within the receiving tray 47. The four corners are limited to prevent the receiving tray 47 from shifting or shaking during movement, ensuring the stability and accuracy of electronic components during the receiving process. Through the cooperation between the side plate 3, synchronous wheel 41, synchronous belt 42, servo motor 43, slide rail 44, moving carrier 45, limit block 46 and receiving tray 47, the two moving carriers 45 achieve independent and precise staggered movement through two sets of power transmission systems. When one moving carrier 45 moves the fully loaded TRAY tray to one side for unloading, the other moving carrier 45 simultaneously moves the empty TRAY tray to the designated position for loading electronic components. This avoids the waiting time for changing TRAY trays in traditional single-station designs, thereby avoiding interruptions in electronic component receiving and improving the continuity of electronic component receiving and overall production efficiency. Furthermore, the tray loading and unloading assembly 5 includes a tray feeding port 51, a fixing frame 52, a pick-and-place assembly 53, and a receiving and feeding assembly 54. The tray feeding port 51 is located on the top of the base 1 on one side of the two side plates 3 that are close to each other. There are two fixing frames 52, which are distributed above the tray feeding port 51 and are fixedly connected to the outer wall of the side plate 3. The pick-and-place assembly 53 is located on the top of the fixing frame 52. The receiving and feeding assembly 54 is located inside the base 1 below the tray feeding port 51. The pick-and-place assembly 53 picks up and lifts empty and full trays, so that the trays are placed into or taken out of the moving carrier 45. The receiving and feeding assembly 54 conveys and picks up empty and full trays. In the specific implementation process, it is worth noting that the tray feeding port 51 serves as a channel for empty trays to enter and full trays to exit, facilitating the removal of empty trays from the loading position inside the base 1 and facilitating the placement of full trays into the stacking position inside the base 1. Through the cooperation between the base 1, tray feeding port 51, fixing frame 52, picking and placing component 53 and receiving and feeding component 54, a complete process of automated tray loading and unloading is formed. By moving the mobile carrier 45 and picking up and lifting the trays, full trays are picked up from the top of the mobile carrier 45 and lowered to the full tray stacking position, and empty trays are picked up from the empty tray stacking position and placed back into the top of the mobile carrier 45, realizing the automated loading and unloading operation of trays onto the mobile carrier 45. Furthermore, the pick-and-place assembly 53 includes a lifting frame 531, a servo cylinder 532, a suction cup 533, and a first guide rod 534. The lifting frame 531 is located below the fixed frame 52. The servo cylinder 532 is fixedly connected to the top of the lifting frame 531, and its output end is fixedly connected to the lifting frame 531. Multiple suction cups 533 are provided and are fixedly connected at equal intervals to the bottom sides of the lifting frame 531. Two first guide rods 534 are provided and are fixedly connected to the top sides of the lifting frame 531 and are slidably connected to the inner wall of the lifting frame 531. The suction cup 533 uses vacuum adsorption to pick up the TRAY disc, and the servo cylinder 532 drives the lifting frame 531 to move up and down, so that the TRAY disc can be placed into or taken out of the mobile carrier 45. In the specific implementation process, it is worth noting that the first guide rod 534 can effectively ensure the stability of the lifting frame 531 during the lifting process, avoiding suction errors caused by shaking. Through the cooperation between the fixed frame 52, the lifting frame 531, the servo cylinder 532, the suction cup 533, and the first guide rod 534, an empty tray filling and full tray stacking system is set below the two fixed frames 52. Among them, the end of the side plate 3 away from the two fixed frames 52 is the electronic component loading position, the middle position of the side plate 3 is the empty TRAY tray filling position, and the side away from the electronic component loading position is the full-load TRAY tray stacking position. The servo cylinder 532 can precisely drive the lifting frame 531 to rise or fall, and then the suction cup 533 can pick up and place the TRAY tray. After the full TRAY tray is picked up from the top of the mobile carrier 45, it is placed into the full tray stacking position inside the base 1. At the same time, the empty TRAY tray is picked up from the bottom and lifted to the waiting position. When the mobile carrier 45, which has completed the unloading, moves to the bottom of the waiting position, the suction cup 533 precisely places the empty TRAY tray on the mobile carrier 45, realizing the automatic unloading and replenishment of the TRAY tray. The specific model of the servo cylinder 532 is not limited, as long as it meets the usage requirements. Furthermore, the material receiving and feeding assembly 54 includes an electric lift 541, a lifting seat 542, a stacking pallet 543, and a second guide rod 544. Two electric lifts 541 are provided, fixedly connected to the top of the inner support plate 2 below the lifting frame 531. The lifting seat 542 is fixedly connected to the top of the output end of the electric lift 541. The stacking pallet 543 is connected to the top of the lifting seat 542, and its inner wall is connected to the receiving tray 47. The second guide rod 544 is fixedly connected to both sides of the bottom of the lifting seat 542 and slidably connected to the inner wall of the inner support plate 2. The electric lift 541 drives the lifting seat 542 to lift and lower, using the lifting seat 542 and the stacking pallet 543 to support empty and full trays, allowing empty trays to be lifted for filling and full trays to be lowered for stacking. In the specific implementation process, it is worth noting that the stacking pallet 543 is used to stack the TRAY trays in an orderly manner so that the stacked TRAY trays can be moved as a whole. Through the cooperation between the electric lift 541, the lifting seat 542, the stacking pallet 543 and the second guide rod 544, the electric lift 541 is controlled to achieve precise lifting and moving of the lifting seat 542, which in turn drives the stacking pallet 543 to move accurately to the designated position. The electric lift 541 drives the lifting seat 542 to rise, lifting and filling empty TRAY trays or smoothly lowering full-load TRAY trays. Under the two fixed frames 52, an efficient empty tray filling and full tray stacking system is formed, which effectively improves the efficiency and accuracy of TRAY tray loading and unloading. The specific model of the electric lift 541 is not limited, as long as it meets the usage requirements. Furthermore, the feeding assembly 54 also includes a limiting plate 545 and a through-beam photoelectric sensor 546. The limiting plate 545 is disposed on both sides of the lifting base 542; the through-beam photoelectric sensor 546 is fixedly connected to the top of the limiting plate 545. The limiting plate 545 limits the stacking tray 543 and the TRAY tray during the lifting process to prevent them from shifting or shaking, and the through-beam photoelectric sensor 546 detects the position status of the top TRAY tray in real time. In the specific implementation process, it is worth noting that during the lifting and lowering of the stacked pallet 543 and the TRAY tray, the limiting plate 545 forms a limit on both sides to prevent the stacked pallet 543 and the TRAY tray from shifting or shaking during the lifting and lowering process, thus ensuring the accuracy and stability of loading and unloading. The through-beam photoelectric sensor 546 monitors the position status of the top TRAY tray in real time. Once the TRAY tray is detected to have reached the designated position, it immediately sends a signal to the control system so that the control system can automatically control the electric lifting machine 541 and adjust the height of the lifting seat 542 in a timely manner to ensure the efficiency and accuracy of the entire loading and unloading process of the TRAY tray. The specific model of the through-beam photoelectric sensor 546 is not limited, as long as it meets the usage requirements. Furthermore, the top of the inner support plate 2 is fixedly connected to both sides of the electric lift 541 with synchronous conveyors 547, which are connected in conjunction with the stacking pallets 543. In the specific implementation process, it is worth noting that after all empty trays are removed or fully loaded trays are stacked to a certain number, the control system automatically controls the electric lift 541 to lower the lifting platform 542 to the low position. The bottom sides of the stacked trays 543 are supported by the synchronous conveyor 547. Then, the synchronous conveyor 547 starts to transport the empty or fully loaded stacked trays 543 to the designated position so that the staff can take them out from the base 1 for replacement. The specific model of the synchronous conveyor 547 is not limited, as long as it meets the usage requirements.
