Description

Technical Field

[0001] This invention relates to the field of conductive connector technology, and more specifically to an automatic handling and unloading device and method for conductive connector plates. Background Technology

[0002] Conductive circuit connection boards, as the foundation of core components of electronic devices, play an important role in the electrical connection and signal transmission of electronic devices. They can ensure the stable transmission of current and signals to guarantee the reliability of electronic device operation. They also occupy little internal space in electronic devices, reducing the size and weight of electronic devices and meeting the high performance and multifunctionality requirements of modern electronic devices.

[0003] For example, patent application number 202223366240.2, published on June 27, 2023, discloses a synchronous processing mechanism for flexible printed circuit boards (FPCs). This mechanism includes an operating table and a synchronous transfer mechanism movably mounted on top of the operating table. A first guide rail is provided on one side of the operating table along the X-axis, and a loading platform is movably mounted on the guide rail. A pre-bending station, a film-tearing station, a bending station, and a unloading platform are sequentially arranged on one side of the loading platform along the X-axis. The synchronous transfer mechanism includes an X-axis module positioned above the operating table along the X-axis. A frame is movably mounted on the X-axis module. A first robotic arm, a second robotic arm, and a third robotic arm are fixedly mounted at equal intervals at the bottom of the frame. A fourth robotic arm is retractably mounted along the X-axis on the side of the frame near the unloading platform.

[0004] The aforementioned literature utilizes robotic arms and vacuum suction heads to achieve synchronous operation of multiple stations and processes between the operating table, synchronous transfer mechanism, loading platform, pre-bending station, film-tearing station, bending station, and unloading platform, thus solving the problems of low processing efficiency and insufficient precision. However, after moving the conductive circuit board to the unloading platform, manual stacking and unloading of the conductive circuit board on the unloading platform is required, which cannot achieve efficient automatic stacking and unloading, resulting in low efficiency and high cost. Summary of the Invention

[0005] This invention provides an automatic handling and unloading device and method for conductive connecting plates, which can achieve efficient automatic stacking and unloading of conductive plates after testing, reducing usage costs and increasing unloading efficiency.

[0006] To achieve the above objectives, the present invention provides an automatic handling and unloading device for conductive connectors, comprising a flipping mechanism, a gantry picking mechanism, a tray gripping mechanism, and a receiving lifting mechanism located below the gantry picking mechanism, all mounted on a frame. Below the tray gripping mechanism are an NG storage mechanism and a tray conveying mechanism. Below the tray conveying mechanism is a discharge conveying assembly. The tray conveying mechanism includes two tray lifting assemblies and two tray conveying assemblies, with the two tray lifting assemblies respectively positioned at both ends of the tray. The output end of the tray lifting assembly is located at the bottom of the tray conveying assembly, driving the tray conveying assembly to move vertically up and down. A tray stacking space is formed between the discharge conveying assembly and the tray conveying assembly. After the tray gripping mechanism grips the trays stacked on the tray conveying mechanism, it moves them to the receiving lifting mechanism. The gantry picking mechanism includes a gantry drive module, a product picking assembly, and a connector picking assembly. The flipping mechanism includes a flipping assembly and a resting platform located below the flipping assembly. After the product picking component moves through the gantry drive module, it picks up the product from the flipping component or the product on the shelf platform and transports it to the material tray located on the receiving lifting mechanism. After the material tray of the receiving lifting mechanism is stacked, the material is output from the material tray stacking space through the discharge conveyor component.

[0007] The above setup allows for the initial stacking of empty pallets on the pallet conveying assembly. Once the pallets are below the pallet gripping mechanism, the pallet lifting assembly raises and lowers the pallet conveying assembly, matching the height of the stacked pallets to the pallet gripping mechanism. The pallet gripping mechanism then picks up the top pallet from the stack and transports it to the receiving lifting mechanism. Simultaneously, the gantry drive module moves the product picking assembly and connector picking assembly to the flipping mechanism to pick up products placed face-up on the platform or products flipped face-up by the flipping assembly. These products are then transported to the receiving lifting mechanism's pallet. Once the pallet is full, the receiving lifting mechanism lowers the full pallet by one pallet height. Simultaneously, the pallet gripping mechanism picks up empty pallets again and stacks them on the full pallet of the receiving lifting mechanism. This process continues until the pallet is fully stacked. Finally, the pallets are lowered onto the discharge conveying assembly and output from the pallet stacking space, automatically completing the full pallet unloading process.

[0008] Furthermore, the gantry material handling mechanism is mounted on the frame, and the gantry drive module is mounted on the frame via the first gantry frame. The gantry drive module includes an X-axis drive module, a Y-axis drive module, and a Z-axis drive module. The output end of the Z-axis drive module is connected to the product handling component via a connecting frame. The product handling component includes a first fixed frame parallel to the Y-axis drive module and connected to the connecting frame, and product adsorption components arranged relatively parallel on both sides of the first fixed frame. The product adsorption component includes a second fixed frame slidably mounted to the first fixed frame and two or more first suction nozzles mounted on the second fixed frame. The first suction nozzles on the same adsorption component are arranged in a straight line.

[0009] The above settings, after the X-axis drive module, Y-axis drive module and Z-axis drive module move to move the product adsorption component directly above the product, so that the product can be adsorbed through the first suction nozzle, thereby realizing product handling.

[0010] Furthermore, a third fixed frame is provided at one end of the first fixed frame. The third fixed frame is provided with two connector picking components arranged side by side, which are respectively arranged corresponding to the two product adsorption components. The connector picking component includes a first driving cylinder connected to the third fixed frame, a first connecting block connected to the output end of the first driving cylinder, a pad connected to one side of the first connecting block, and electric grippers located on both sides of the pad. An accommodating space is formed between the electric grippers and the pad.

[0011] The above settings, after the X-axis drive module, Y-axis drive module and Z-axis drive module move the position, enable the connector picking component and the adsorption component to move synchronously. The connector picking component can adjust the distance between the connector and the electric gripper and the pad in the vertical direction, so that the top of the connector abuts against the pad. Then, the electric gripper can clamp the connector from both sides to transport the connector.

[0012] Furthermore, the two ends of the material tray gripping mechanism are set above the machine frame via the second gantry frame. The material tray gripping mechanism includes a moving module, a fourth fixed frame, and a material tray adsorption assembly connected to the fourth fixed frame. There are two moving modules, which are respectively set on the two second gantry frames. The two ends of the fourth fixed frame are respectively connected to the output end of the moving module. The material tray adsorption assembly includes a fifth fixed frame and two or more second suction nozzles connected to the fifth fixed frame.

[0013] The above configuration enables the moving module to drive the tray adsorption component to move horizontally back and forth between the tray conveying mechanism and the receiving lifting mechanism, thereby transporting the trays stacked on the tray conveying mechanism to the receiving lifting mechanism.

[0014] Furthermore, the receiving lifting mechanism includes a first fixed base connected to the frame, a receiving lifting assembly disposed on the first fixed base, a receiving drive assembly connected to the receiving lifting assembly, and auxiliary assemblies located on both sides of the first fixed base. A first guide rod is provided on the first fixed base and on both sides of the receiving drive assembly. A second fixed base is provided at the upper end of the first guide rod. The receiving drive assembly is disposed on the second fixed base. The receiving lifting assembly includes a lifting plate sleeved on the first guide rod and two or more material trays disposed on one side of the lifting plate. Two or more first limiting rods are provided between the first fixed base and the second fixed base and penetrate the lifting plate. A first limiting post is provided on the first fixed base. The receiving drive assembly includes a receiving drive component and a lead screw connected to the receiving drive component. The lead screw is screwed to a lead screw nut disposed at the bottom of the lifting plate. The auxiliary assemblies include an auxiliary base disposed on the frame and two auxiliary rods fixed on the auxiliary base.

[0015] The above settings, under the action of the receiving drive component, can drive the receiving lifting component to rise and fall in the numerical direction. The first guide rod can play a guiding role. At the same time, by setting the first limit post, the descent transition of the lifting plate can be restricted, so that the material trays stacked on the material tray pallet just fall onto the discharge conveying component. In addition, the first limit post can make the material trays stacked on the material tray pallet.

[0016] Furthermore, a tray straightening mechanism is provided between the receiving lifting mechanism and the tray conveying mechanism. The tray straightening mechanism includes a straightening rod and a straightening drive assembly connected to both ends of the straightening rod. The straightening drive assembly includes a third fixed seat on the frame, a second drive cylinder fixed on the third fixed seat, a first sliding block connected to the output end of the second drive cylinder, and a fixed rod fixed on the third fixed seat. The two ends of the fixed rod are connected to the third fixed seat through a second connecting block. The first sliding block is slidably connected to the fixed rod, and the straightening rod is connected to the first sliding block.

[0017] The above configuration allows the first sliding block to slide on the fixed rod via the second drive cylinder and the sliding distance to be limited by the second connecting block, thereby driving the straightening rod to move horizontally and straightening the pallets stacked on the pallet tray to prevent the stacked pallets from deviating from their position.

[0018] Furthermore, the NG material storage mechanism includes a material storage rack and a material storage plate disposed on the material storage rack. The two ends of the material storage rack are slidably connected to the first slide rail on the second gantry frame through the first slider. A second guide rod is disposed on the second gantry frame and above the first slide rail. A guide slider connected to the material storage rack is sleeved on the second guide rod.

[0019] With the above setup, if a product is damaged while being transported to the receiving lifting mechanism's tray, the tray will be moved to the NG storage plate by the tray gripping mechanism, so that the defective product can be manually pulled to retrieve it.

[0020] Furthermore, the tray lifting assembly includes a fourth fixed seat mounted on the frame, a lifting drive component mounted on the fourth fixed seat, a third connecting block slidably connected to the fourth fixed seat, and a bracket fixed on the third connecting block. The output end of the lifting drive component is drively connected to the third connecting block. The tray positioning assembly located on one side of the tray lifting assembly includes a fifth fixed seat mounted on the frame, a third drive cylinder mounted on the fifth fixed seat, and a fourth drive cylinder located above the third drive cylinder and fixed on the fifth fixed seat. The output end of the third drive cylinder is connected to a lifting block, and the output end of the fourth drive cylinder is connected to a positioning block. The tray conveying assembly includes a first conveyor belt mounted on the bracket and a first drive motor for driving the first conveyor belt.

[0021] With the above setup, after the material trays are stacked on the material tray conveying assembly, the material trays are moved by the material tray conveying assembly. Then, the material tray lifting assembly moves the material tray conveying assembly up and down in the vertical direction. The fourth drive cylinder of the material tray positioning assembly drives the positioning block to position and clamp the material tray from both ends of the material tray and correct its position. Then, the lifting block of the third drive cylinder of the material tray positioning assembly lifts the top layer of the material tray stack, making it easier for the material tray gripping mechanism to adsorb and grip the top layer of the material tray stack.

[0022] Furthermore, there are two discharge conveying components, located below the material tray conveying component. The length of the discharge conveying component is greater than the length of the material tray conveying component, and the distance between the two discharge conveying components matches the length of the material tray.

[0023] The above configuration facilitates the material tray in the receiving lifting mechanism to descend onto the discharge conveying component after the full tray is stacked, so that both ends of the full tray abut against the discharge conveying component, and the material is discharged by the discharge conveying component.

[0024] The present invention also provides an automatic handling and unloading method for conductive connecting plates, comprising the following steps:

[0025] S1 uses the flipping component to adsorb the tested product onto the shelf platform. Then, the gantry drive module moves the product adsorption component to the shelf platform or above the flipping component to adsorb the product on the shelf platform or the product after the flipping component has been flipped 180°.

[0026] After S2 stacks the material trays on the material tray conveying assembly, the material trays are moved by the material tray conveying assembly. Then, the material tray lifting assembly drives the material tray conveying assembly to rise and fall in the vertical direction. The material tray positioning assembly first positions and clamps the material trays from both ends of the material trays by positioning blocks and then lifts the top layer of the material tray stack by the lifting blocks of the material tray positioning assembly.

[0027] The S3 mobile module drives the tray adsorption component to grab the trays stacked on the tray conveyor mechanism, then moves horizontally between the tray conveyor mechanism and the receiving lifting mechanism, and transports them to the tray pallet of the receiving lifting mechanism.

[0028] S4 uses the product adsorption component to transport the product to the tray of the receiving lifting mechanism. After the tray is full, the receiving lifting mechanism lowers the full tray by one tray height. At the same time, the tray grabbing mechanism grabs the empty tray again and stacks it on the full tray of the receiving lifting mechanism.

[0029] After the full tray is stacked, the tray pallet drives the stacked full tray to descend onto the discharge conveyor component, and outputs it from the tray stacking space through the discharge conveyor component, completing the unloading of the full tray.

[0030] The above method first uses a product adsorption component to transport the product to the tray of the receiving and lifting mechanism. Then, the gantry material handling mechanism transports the product while the empty trays are positioned and adjusted by the tray conveying mechanism. After adjustment, the tray grabbing mechanism grabs and transports the trays to the receiving and lifting mechanism for full-tray stacking. After full-tray stacking is completed, the material is unloaded by the discharge conveying component. This method enables efficient and automatic stacking and unloading of conductive boards after testing, reducing usage costs and increasing unloading efficiency.

[0031] The beneficial effects of this invention are:

[0032] First, empty pallets are stacked on the pallet conveying assembly. After being conveyed to the area below the pallet gripping mechanism, the pallet lifting assembly raises and lowers the pallet conveying assembly, matching the height of the stacked pallets with that of the pallet gripping mechanism. Then, the pallet gripping mechanism grabs the top pallet from the stack and transports it to the receiving lifting mechanism. Simultaneously, the gantry drive module moves the product picking assembly and connector picking assembly to the flipping mechanism to flip the products or flipping components placed face up on the platform. The product is adsorbed and then transported to the tray of the receiving lifting mechanism. After the tray is full, the receiving lifting mechanism lowers the full tray by one tray height. At the same time, the tray gripping mechanism grabs an empty tray and stacks it on the full tray of the receiving lifting mechanism. After the tray is full, it is lowered to the discharge conveyor component and output from the tray stacking space through the discharge conveyor component. The full tray stacking and unloading is automatically completed, which can achieve efficient and automatic stacking and unloading of conductive boards after testing, reduce the use cost and increase the unloading efficiency.

Detailed Implementation

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] like Figures 1-8As shown, an automatic conveying and unloading device for conductive connecting plates includes a flipping mechanism, a gantry material handling mechanism 2, a material tray gripping mechanism 3, and a material receiving and lifting mechanism 4 located below the gantry material handling mechanism 2, all mounted on a frame 1c. Below the material tray gripping mechanism 3 are an NG storage mechanism 5 and a material tray conveying mechanism 6. Below the material tray conveying mechanism 6 is a discharge conveying assembly 48c. The material tray conveying mechanism 6 includes two material tray lifting assemblies and two material tray conveying assemblies. The two material tray lifting assemblies are respectively located at both ends of the material tray. The output end of the component is located at the bottom of the tray conveying component, which drives the tray conveying component to rise and fall vertically. A stacking space 100 for accommodating trays is formed between the discharge conveying component 48c and the tray conveying component. After the tray gripping mechanism 3 grips the trays stacked on the tray conveying mechanism, it moves to the receiving lifting mechanism 4. The gantry picking mechanism 2 includes a gantry drive module, a product picking component, and a connector picking component. The flipping mechanism includes a flipping component b4 and a shelf platform (not shown in the figure) located below the flipping component b4. After the product picking component moves through the gantry drive module, it grips the product on the flipping component or the product on the shelf platform and transports it to the tray located on the receiving lifting mechanism. After the trays of the receiving lifting mechanism are stacked, the material is output from the stacking space 100 through the discharge conveying component 48c.

[0045] In this embodiment, as Figure 8 As shown, the flipping assembly b4 includes a column b41, a vertical guide rail b42, a sixth fixed seat b43, a flipping plate b44, and a rotating shaft b45. Columns b41 are respectively arranged on both sides of the frame 1c. A base b46 connected to the top of each column b41 by a reinforcing rib b47 is provided. When the rotating shaft b45 is driven by a motor b48, the flipping assembly b44 maintains a certain rigidity and stability. The side of the base b46 facing the center of the frame 1c is fixedly connected to the vertical guide rail b42. The sixth fixed seat b43 is slidably connected to the vertical guide rail b42. The sixth fixed seat b44 is located at one end of the flipping plate b44. A rotating shaft b45 is provided on the 3rd column. A motor b48 is installed on the sixth fixed seat b43 located at the other end of the flip plate b44. The rotating shaft b45 is installed on the output shaft of the motor b48. The flip plate b44 is arranged between the two columns b41. Both ends of the flip plate b44 are connected to the rotating shaft b45 by fixing parts. Two or more adsorption components b221 are provided on the bottom end of the flip plate b44. When it is necessary to flip the product, the adsorption components b221 move vertically through the vertical guide rail b42 to adsorb the product. After adsorbing the product, the rotating shaft b45 drives the flip plate b44 to rotate 180°.

[0046] like Figure 2 and Figure 3As shown, the gantry material handling mechanism 2 is mounted on the frame 1c. The gantry drive module is mounted on the frame 1c via the first gantry frame 2c. The gantry drive module includes an X-axis drive module 3c, a Y-axis drive module 4c, and a Z-axis drive module 5c. The output end of the Z-axis drive module 5c is connected to the product handling assembly via a connecting frame 6c. The product handling assembly includes a first fixed frame 7c parallel to the Y-axis drive module 4c and connected to the connecting frame 6c, and product adsorption components arranged parallel to each other on both sides of the first fixed frame 7c. The product adsorption components include components connected to the first fixed frame 7c. The second fixed frame 8c is slidably set, and there are two or more first suction nozzles 9c set on the second fixed frame 8c. The first suction nozzles 9c on the same suction component are in the same straight line. In this embodiment, the sliding setting of the first fixed frame 7c and the second fixed frame 8c can be realized by sliding the slider and the slide rail. In this way, after the position is moved by the X-axis drive module 3c, the Y-axis drive module 4c and the Z-axis drive module 5c, the product suction component can be moved to directly above the product so that the product can be suctioned by the first suction nozzles 9c, thereby realizing product handling.

[0047] like Figure 2 and Figure 3 As shown, a third fixed frame 10c is provided at one end of the first fixed frame 7c. Two connector picking components are arranged side by side on the third fixed frame 10c, corresponding to the two product adsorption components respectively. The connector picking component includes a first drive cylinder 11c connected to the third fixed frame 10c, a first connecting block 12c connected to the output end of the first drive cylinder 11c, a pad 13c connected to one side of the first connecting block 12c, and electric grippers 14c located on both sides of the pad 13c. An accommodating space 15c is formed between the electric grippers 14c and the pad 13c. After the position is moved by the X-axis drive module 3c, the Y-axis drive module 4c and the Z-axis drive module 5c, the connector picking component and the adsorption component can move synchronously. The connector picking component can adjust the distance between the connector and the electric grippers 14c and the pad 13c in the vertical direction, so that the top of the connector abuts against the pad 13c. Then, the electric grippers 14c can clamp the connector from both sides to realize the transport of the connector.

[0048] like Figure 1 and Figure 6As shown, the two ends of the material tray gripping mechanism 3 are set above the frame 1c via the second gantry 16c. The material tray gripping mechanism includes a moving module 17c, a fourth fixed frame 18c, and a material tray adsorption assembly connected to the fourth fixed frame 18c. There are two moving modules 17c, which are respectively set on the two second gantry 16c. The two ends of the fourth fixed frame 18c are respectively connected to the output end of the moving module 17c. The material tray adsorption assembly includes a fifth fixed frame 19c and two or more second suction nozzles (not shown in the figure) connected to the fifth fixed frame 19c. This allows the moving module 17c to drive the material tray adsorption assembly to move horizontally back and forth between the material tray conveying mechanism 6 and the receiving lifting mechanism 4, thereby transporting the material trays stacked on the material tray conveying mechanism 6 to the receiving lifting mechanism 4 one by one.

[0049] like Figure 1 and Figure 4 As shown, the receiving and lifting mechanism 4 includes a first fixed base 20c connected to the frame 1c, a receiving and lifting assembly disposed on the first fixed base 20c, a receiving and driving assembly connected to the receiving and lifting assembly, and auxiliary assemblies located on both sides of the first fixed base 20c. A first guide rod 21c is provided on the first fixed base 20c and on both sides of the receiving and driving assembly. A second fixed base 22c is provided at the upper end of the first guide rod 21c. The receiving and driving assembly is disposed on the second fixed base 22c. The receiving and lifting assembly includes a lifting plate 23c sleeved on the first guide rod 21c and two or more material tray supports 24c disposed on one side of the lifting plate 23c. Two or more first limiting rods 25c are provided between the first fixed base 20c and the second fixed base 22c and penetrate the lifting plate 23c. A first limiting rod 25c is provided on the first fixed base 20c. The limiting post 26c and the receiving drive assembly include a receiving drive component and a lead screw 201c that is connected to the receiving drive component. The lead screw 201c is screwed to a nut 202c located at the bottom of the lifting plate 23c. The auxiliary assembly includes an auxiliary seat located on the frame 1c and two auxiliary rods 204c fixed on the auxiliary seat 203c. In this embodiment, the receiving drive component can be a drive motor connected to a drive wheel and a driven wheel connected by a transmission belt. Under the action of the receiving drive assembly, the receiving lifting assembly can be driven to rise and fall in the vertical direction. The first guide rod 21c can play a guiding role. At the same time, by setting the first limiting post 26c, the lowest position of the lifting plate 23c can be limited so that the material trays stacked on the material tray support plate 24c just fall onto the discharge conveying assembly 48c.

[0050] like Figure 1 and Figure 4As shown, a tray straightening mechanism is provided between the receiving lifting mechanism 4 and the tray conveying mechanism 6. The tray straightening mechanism includes a straightening rod 27c, a straightening block 270c disposed on the straightening rod 27c, and a straightening drive assembly connected to both ends of the straightening rod 27c. The straightening drive assembly includes a third fixed seat 28c disposed on the frame 1c, a second drive cylinder 29c fixed on the third fixed seat 28c, a first sliding block 30c connected to the output end of the second drive cylinder 29c, and a fixed rod 31c fixed on the third fixed seat 28c. The two ends of the fixed rod 31c are connected to the third fixed seat 28c through a second connecting block 32c. The first sliding block 30c is slidably connected to the fixed rod 31c, and the straightening rod 27c is connected to the first sliding block 30c. The first sliding block 30c can be driven to slide on the fixed rod 31c by the second driving cylinder 29c, and the sliding distance can be limited by the second connecting block 32c. This causes the straightening rod 27c to move horizontally. The straightening block 270c set on the straightening rod 27c corrects the material trays that are transported to the material tray pallet 24c for stacking, thus preventing the stacked material trays from deviating from their position.

[0051] like Figure 6 As shown, the NG storage mechanism includes a storage rack 333c and a storage plate 34c mounted on the storage rack 333c. The two ends of the storage rack 333c are slidably connected to the first slide rail 35c on the second gantry frame 16c via first sliders (not shown in the figure). A second guide rod 36c is provided on the second gantry frame 16c and above the first slide rail 35c. A guide slider 37c connected to the storage rack 333c is sleeved on the second guide rod 36c. In this way, when a product on the receiving lifting mechanism is damaged, the receiving lifting mechanism will move the receiving tray to the storage plate 34c of the NG storage mechanism, so that the storage rack 333c can be manually pulled to retrieve the defective product.

[0052] like Figure 5 and Figure 7As shown, the material tray lifting assembly includes a fourth fixed seat 38c mounted on the frame 1c, a lifting drive component mounted on the fourth fixed seat 38c, a third connecting block 39c slidably connected to the fourth fixed seat 38c, and a bracket 40c fixed on the third connecting block 39c. The output end of the lifting drive component is drively connected to the third connecting block 39c. The material tray positioning assembly located on one side of the material tray lifting assembly includes a fifth fixed seat 41c mounted on the fourth fixed seat 38c, a third drive cylinder 42c mounted on the fifth fixed seat 41c, and a fourth drive cylinder 43c located above the third drive cylinder 42c and fixed on the fifth fixed seat 41c. The output end of the third drive cylinder 42c is connected to a lifting block 44c, and the fourth drive cylinder 43c... The output end is connected to a positioning block 45c; the tray conveying assembly includes a first conveyor belt 46c mounted on a bracket 40c and a first drive motor 47c for driving the first conveyor belt 46c. After the trays are stacked on the tray conveying assembly, the trays are moved by the tray conveying assembly. Then, the tray lifting assembly moves the tray conveying assembly vertically. The fourth drive cylinder 43c of the tray positioning assembly drives the positioning block 45c to position and clamp the trays from both ends, correcting their position. Then, the lifting block 44c of the third drive cylinder 42c of the tray positioning assembly lifts the top tray in the tray stack, facilitating the tray gripping mechanism to adsorb and grip the top tray. In this embodiment, the lifting drive can be a drive motor that drives a lead screw via a transmission belt, thereby enabling the lead screw to drive the lead screw nut on the third connecting block 39c.

[0053] like Figure 7 As shown, there are two discharge conveying components 48c, located below the tray conveying component. The length of the discharge conveying component 48c is greater than the length of the tray conveying component, and the end of the discharge conveying component 48c near the receiving lifting mechanism 4 protrudes from the tray conveying component. The distance between the two discharge conveying components 48c matches the length of the tray support plate 24c, so that after the tray support plate 24c in the receiving lifting mechanism carries the full tray, it descends onto the discharge conveying component 48c, so that the two ends of the full tray abut against the discharge conveying component 48c, and then the discharge conveying component 48c drives the stacked tray to output material, thus realizing the unloading. In this embodiment, the structure of the discharge conveying component 48c is the same as that of the tray conveying component, and will not be described in detail here.

[0054] An automated handling and unloading method for a conductive connecting plate specifically includes the following steps:

[0055] S1 uses the flipping component to adsorb the tested product onto the placement platform. Then, the gantry drive module moves the product adsorption component above the placement platform or the flipping component to adsorb the product on the placement platform or the product after the flipping component has been flipped 180°.

[0056] After S2 stacks the material trays on the material tray conveying assembly, the material trays are moved by the material tray conveying assembly. Then, the material tray lifting assembly drives the material tray conveying assembly to rise and fall in the vertical direction. The material tray positioning assembly first positions and clamps the material trays from both ends of the material trays through the positioning blocks 45c to correct their position. Then, the lifting blocks 44c of the material tray positioning assembly lift up the top layer of the material tray stack.

[0057] The S3 mobile module 17c drives the tray adsorption component to grab the trays stacked on the tray conveying mechanism, then moves horizontally between the tray conveying mechanism and the receiving lifting mechanism, and transports them to the tray pallet 24c of the receiving lifting mechanism.

[0058] S4 uses the product adsorption component to transport the product to the tray 24c of the receiving lifting mechanism. After the tray is full, the receiving lifting mechanism lowers the full tray by one tray height. At the same time, the tray grabbing mechanism grabs the empty tray and stacks it on the full tray of the receiving lifting mechanism.

[0059] After the full tray is stacked, the tray support plate 24c drives the stacked full tray to descend onto the discharge conveyor component 48c, and outputs it from the tray stacking space through the discharge conveyor component 48c, completing the unloading of the full tray.

[0060] In this embodiment, step S3 further includes:

[0061] When the product on the receiving lifting mechanism is a defective product, the material tray lifting component drives the material tray conveying component to descend, causing the empty material trays stacked on the material tray conveying component to descend. This allows the material tray gripping mechanism to move the material tray on the receiving lifting mechanism to the storage plate 34c of the NG storage mechanism, so that the defective product can be manually pulled by the storage rack 333c.

[0062] The working principle of this invention is as follows: First, material trays are stacked on the material tray conveying assembly. At this time, the empty material trays are stacked. After being conveyed to the area below the material tray gripping mechanism, the material tray lifting assembly drives the material tray conveying assembly to rise and fall, so that the height of the stacked material trays matches that of the material tray gripping mechanism. Then, the material tray gripping mechanism can grab the top material tray in the stack and transport it to the receiving lifting mechanism. At the same time, the gantry drive module enables the product picking assembly and connector picking assembly to move synchronously to the flipping mechanism to adsorb the products placed face up on the placement platform or the products that have been flipped face up by the flipping assembly. Then, they are transported to the material tray of the receiving lifting mechanism. After the material tray is full, the receiving lifting mechanism drives the full material tray to fall by one material tray height. At the same time, the material tray gripping mechanism grabs empty material trays again and stacks them on the full material tray of the receiving lifting mechanism. After the full material tray is stacked, it falls to the discharge conveying assembly 48c and is output from the material tray stacking space through the discharge conveying assembly 48c, automatically completing the full material tray unloading.
