Description

Technical Field

[0001] This application relates to the technical field of workpiece conveying, and in particular to a workpiece conveying device and conveying method. Background Technology

[0002] In the process of producing injection molded products, conveyor belts at different locations are often required for transportation. However, the transportation paths between two adjacent conveyor belts are different, so the conveyor belts cannot be directly transported to each other. Therefore, a conveying device is needed to grab the workpiece from the previous conveyor belt and transport it to the next conveyor belt.

[0003] Existing conveying devices typically use multiple fixed suction cups to grip workpieces. However, workpieces vary in shape and size, and the fixed suction cups are difficult to adapt to gripping different workpieces. This results in poor stability during workpiece transport, making it easy for workpieces to fall and be damaged during gripping, thus reducing workpiece quality. Alternatively, to improve stability during transport, the moving speed needs to be appropriately reduced, but this reduces transport efficiency, making it impossible to achieve both workpiece quality and transport efficiency simultaneously. Summary of the Invention

[0004] In order to improve both the quality of the workpiece and the conveying efficiency, this application provides a workpiece conveying device and a conveying method.

[0005] Firstly, the workpiece conveying device provided in this application adopts the following technical solution: A workpiece conveying device includes a body, a first movable seat and a second movable seat, and a conveying mechanism. The first movable seat is horizontally slidably mounted on the body, and the second movable seat is vertically slidably mounted on the first movable seat. The conveying mechanism includes: Multiple conveyor plates each have strip-shaped conveying holes along their own length; Multiple locking components are mounted on the movable base 2 and pass through the conveying hole. After the locking components are unlocked, the conveying plate slides and rotates with the locking components through the conveying hole. After the position of the conveying plate is adjusted, the locking components are activated to press against the conveying plate for positioning. Multiple adsorption components are mounted on multiple conveyor plates and their positions can be adjusted along the conveyor holes.

[0006] By adopting the above technical solution, the locking component is unlocked, and the conveyor plate can rotate around the locking component and / or move along the conveying hole. The locking component can guide the conveyor plate during movement and rotation. After adjustment, the locking component presses against the conveyor plate for positioning, thereby adjusting the position of multiple adsorption components located on the conveyor plate. Moreover, the adsorption components can also move along the conveying hole to adjust the position of a single adsorption component. The position and angle of multiple adsorption components can be adjusted as needed, so that the position and angle of multiple adsorption components can better adapt to the size and shape of the workpiece, improving the adsorption and positioning effect of the workpiece, while improving the quality of the workpiece and the conveying efficiency.

[0007] The conveyor plate rotates and moves, and the conveyor holes guide the adjustment of the conveyor plate and multiple adsorption components, enabling better and faster adjustment, improving the convenience and accuracy of adjustment, and further improving the quality of the workpiece and the conveying efficiency.

[0008] Optionally, the adsorption component includes: The movable column is slidably set on the conveying hole and is threadedly connected to a positioning nut that presses against the upper and lower surfaces of the conveying plate for positioning. The movable rod is vertically slidably installed on the movable column; The pressure plate and the mounting plate are respectively set on the top and bottom of the moving rod; The elastic element is sleeved on the moving rod and presses against the mounting plate and the moving column for positioning, so that the pressing plate presses against the moving column for positioning; A suction cup, mounted on a mounting plate, is used to adsorb and position the workpiece. The air tube connects to the mounting plate and communicates with the inside of the suction cup, controlling the air intake or exhaust of the suction cup.

[0009] By adopting the above technical solution, when it is necessary to adjust the position of the adsorption component, one of the positioning nuts is turned to unlock it, and then the moving column is pushed to move and adjust the position of a single adsorption component. After the adjustment is completed, the positioning nut is turned to press against the conveyor plate for positioning. At the same time, the position of the adsorption component in the vertical direction can also be adjusted by adjusting both positioning nuts, which can greatly improve the convenience of adjustment, improve the quality of the workpiece and the conveying efficiency.

[0010] The moving seat moves downward, driving the conveyor plate and the adsorption assembly to move downward simultaneously, causing the suction cup to press against the workpiece. The suction cup is squeezed and air is expelled through the air pipe. After the suction cup continues to be squeezed, it pushes the moving rod, the mounting plate and the pressing plate to move upward for buffering. The upward movement of the mounting plate squeezes the elastic element, which can expel as much air as possible from the suction cup. The air pipe is closed, allowing the suction cup to adhere to the workpiece for positioning.

[0011] As the conveyor plate moves upward, the elastic element pushes the suction cup, moving rod, and pressing plate downward until the pressing plate presses against the moving column for positioning. Then, the moving column, pressing plate, moving rod, suction cup, and workpiece move upward simultaneously to grasp the workpiece for conveying. The workpiece is then conveyed to another conveyor belt. The air pipe is opened, and air enters the suction cup. Under the action of elasticity, the suction cup returns to its original position, and the gas pushes the workpiece downward to fall onto the conveyor belt for further conveying.

[0012] By combining the suction cup and the elastic element, the suction cup is squeezed and pushes the moving rod to move, so that the suction cup is squeezed into place. It can also buffer the force on the workpiece, making the suction cup have a greater adsorption force on the workpiece and reducing the damage to the workpiece, thereby further improving the quality of the workpiece and the conveying efficiency.

[0013] Optionally, it may also include multiple support structures and / or fulcrums; The support mechanism is mounted on the moving column and is positioned on the lower surface of the workpiece after the suction cup drives the workpiece to move upward; after the suction cup unlocks the workpiece, the workpiece pushes the support mechanism to unlock the lower surface of the workpiece under the action of gravity. The supporting mechanism is mounted on movable seat one and movable seat two. When movable seat two moves upward, it drives the supporting mechanism to support the lower surface of the workpiece for unlocking. When movable seat two moves downward, it first drives the supporting mechanism to rotate to the outside of the workpiece for unlocking. Movable seat two continues to move downward to complete the conveying of the workpiece.

[0014] By adopting the above technical solution, relying solely on suction cups to adsorb and position the workpiece reduces the stability of the workpiece during transport. This is especially true for heavy workpieces, where the stability is even worse, thus slowing down the workpiece's movement speed. As a result, the quality of the workpiece and the transport efficiency cannot be achieved simultaneously.

[0015] After the moving column moves down to drive the suction cup to adsorb and position the workpiece, the moving column moves up to drive the workpiece to detach from the conveyor belt. The support mechanism supports the workpiece on its lower surface for positioning. This allows the suction cup and multiple support mechanisms to work together to position the workpiece, thereby improving the positioning effect. After the workpiece is conveyed, the suction cup unlocks its adsorption and positioning of the workpiece. Under the action of gravity, the workpiece pushes the support mechanism to unlock its positioning. Therefore, the quality of the workpiece and the conveying efficiency are improved at the same time.

[0016] When the second movable seat moves upward, it drives the workpiece to move upward. The upward movement of the second movable seat drives the supporting mechanism to rotate and abut against the lower surface of the workpiece for positioning. This allows the suction cup and the supporting mechanism to support the workpiece during movement, improving the adsorption and positioning effect of the workpiece. The second movable seat drives the workpiece to move from one conveyor belt to the top of another conveyor belt. When the second movable seat moves downward, it causes the supporting mechanism to unlock the positioning effect of the workpiece. Then, the workpiece is transported and placed on the conveyor belt, thereby improving both the quality of the workpiece and the conveying efficiency.

[0017] The support mechanism can position the workpiece on its lower surface as soon as it separates from the conveyor belt, providing timely positioning and thus improving the positioning effect. Compared to the support mechanism, the support mechanism positions the workpiece based on the position of the movable seat, which further improves the stability of the workpiece support and has a simple structure. Thus, through the cooperation of the support mechanism and / or the support mechanism, the quality of the workpiece and the conveying efficiency are improved at the same time.

[0018] Optionally, the support mechanism includes: The support base is connected to the movable column via a connecting component; The slide is inclined on the support base with its bottom end facing the side close to the suction cup and has a slider that slides on it. A support rod is mounted on the slider and positioned vertically downwards. The support block is set on the bottom end of the support rod and has an inclined support surface that allows it to extend under the workpiece. The elastic element is set on the slide rail and connected to the slider, so that the slider tends to move downward and closer to the workpiece; The push rod is vertically slidably mounted on the support base and is detachably connected to the pressure plate; The push block is set on the top of the support rod and both the push block and the push rod are provided with push surfaces that are in contact with each other and in an inclined state; The flexible plug-in assembly is mounted on the support base and is plugged into the pressure plate and the moving column for positioning under the pushing action of the support rod; The pressure plate moves upward and causes the support block to move downward under the elastic force of the elastic element, so that the support block abuts against the workpiece and the conveyor belt for positioning and pushes the elastic plug-in assembly to be plugged into and positioned on the pressure plate and the moving column. The upward movement of the moving column causes the workpiece to move upward and detach from the conveyor belt. The support rod moves downward under the action of the elastic element, causing the support block to abut against the lower surface of the workpiece. After the adsorption component unlocks the workpiece, the workpiece pushes multiple support blocks away from the workpiece under the action of gravity and the elastic force of the suction cup, thereby unlocking the workpiece and pulling the elastic plug-in component to detach from the pressure plate and the moving column.

[0019] By adopting the above technical solution, the conveyor plate drives multiple moving columns and multiple suction cups to move downwards simultaneously, causing the suction cups to press against the workpiece and push the pressure plate upwards. The upward movement of the pressure plate drives the push rod upwards, causing the two push surfaces to separate. The elastic component pushes the support rod, support block, and push block downwards, causing the support block to abut against the workpiece and the conveyor belt for positioning, keeping the two push surfaces in a separated state. At this time, the downward movement of the conveyor plate and moving columns stops. When the support rod moves downwards, it pushes the elastic plug-in component to be plugged into and installed between the pressure plate and the moving column for positioning, preventing the pressure plate from moving back.

[0020] The conveyor plate and moving column move upward, and the moving column pushes the pressure plate and suction cups upward, causing the workpiece to separate from the conveyor belt. At the same time, the upward movement of the pressure plate drives the support base, push rod, and slide to move upward away from the push block. However, due to the downward pushing force of the elastic component, the slider slides downward at an angle on the slide. The sliding of the slider drives the support rod, support block, and push block to move downward and closer to the workpiece at the same time, so that the support block presses against the lower surface of the workpiece for positioning, until the two pushing surfaces on the push block and push rod abut against each other again for positioning, and / or the side wall of the workpiece abuts against the support rod for positioning, so that multiple suction cups and multiple support blocks cooperate to position the workpiece.

[0021] After the workpiece is conveyed onto another conveyor belt, multiple suction cups release their force on the workpiece. Under the action of gravity and the supporting surface, the workpiece pushes the support block upwards away from the workpiece. At the same time, when the deformed suction cups recover, they generate a downward pushing force on the workpiece. The upward movement of the support block drives the support rod upwards. The upward movement of the support rod pulls the elastic plug-in assembly away from the pressure plate and the moving column. The pressure plate and the push rod move back under the action of the elastic element. The return of the push rod pushes the support rod and the support block back. In this way, multiple support rods and multiple support blocks work together to return to their original positions, thereby facilitating the positioning of the next workpiece and improving the quality of the workpiece and the conveying efficiency.

[0022] When gripping workpieces of different sizes and shapes, it is necessary to adjust the positions of the adsorption component and the support mechanism simultaneously. Therefore, by connecting the components, the positions of the adsorption component and the support mechanism can be adjusted at the same time, making the adjustment more convenient and improving the conveying efficiency.

[0023] Optionally, the resilient plug-in assembly includes: The plug rod is slidably mounted on the support base along the direction perpendicular to the movement of the pressure plate and is rotatably equipped with ball bearings; The mounting block is vertically slidably mounted on the support rod; The elastic pusher is connected to the plug rod and the mounting block at both ends respectively. When the support rod moves down, the elastic pusher pushes the ball bearings to support the pressure plate and the moving column for positioning. When the support rod moves up, it pulls the plug rod to disengage from the pressure plate and the moving column.

[0024] By adopting the above technical solution, when the support rod moves down and approaches the workpiece, the mounting block and the support rod slide relative to each other to maintain their vertical positions. At the same time, the support rod pushes the mounting block horizontally closer to the pressure plate. The movement of the mounting block pushes the plug-in rod to be inserted and installed between the pressure plate and the moving column through the elastic pusher. This allows multiple ball bearings to be positioned on the side wall of the opposite side of the pressure plate and the moving column, thereby preventing the pressure plate from moving back towards the moving column. As the support rod continues to move down and approach the suction cup and the workpiece, the support rod continues to push the plug-in rod to move through the mounting block and the elastic pusher. When the support rod moves up and away from the workpiece, it pulls the plug-in rod out from between the pressure plate and the moving column.

[0025] By having the insertion rod move in a direction perpendicular to the pressure plate, the insertion rod can be inserted between the pressure plate and the moving column, thus achieving good positioning of both. This simple structure enables positioning, and the ball bearings reduce resistance during the insertion rod's movement, allowing for locking or unlocking of the pressure plate and improving workpiece quality and conveying efficiency.

[0026] Optionally, the plug rod has a plug-in surface that facilitates plugging and installation between the pressure plate and the movable column.

[0027] By adopting the above technical solution, even when the gap between the pressure plate and the moving column is small, the plug-in rod can still be plugged into the pressure plate and the moving column, which improves the quality of the workpiece and the conveying efficiency.

[0028] Optionally, the connection component includes: A connecting ring is sleeved on the movable column, and the positioning nut pushes the connecting ring to press against the conveyor plate for positioning. A connecting rod is mounted on the connecting ring and is arranged radially along the connecting ring. An adjusting rod is mounted on the support base and slides radially along the connecting ring onto the connecting rod. The connecting screw is threaded onto the connecting rod and presses against the adjusting rod for positioning.

[0029] By adopting the above technical solution, the positioning nut is turned to unlock, and then the moving column can be pushed to move and adjust the position of the adsorption component and the support mechanism. At the same time, the connecting ring can be rotated to adjust the angle of the support mechanism. After the connecting screw is unlocked, the position of the support seat and the support mechanism can also be adjusted, so that the support mechanism and the adsorption component can better adapt to the conveying of workpieces of different sizes and shapes, further improving the workpiece quality and conveying efficiency.

[0030] Optionally, the locking component includes: The locking post and the locking block are provided, wherein the locking post is disposed on the locking block and extends into the conveying hole, and the movable seat is provided with a plurality of threaded holes spaced apart and threadedly connected to the locking screw. The locking screw passes through the locking block and the locking post and is threaded into the threaded hole, causing the locking block to press against the conveyor plate for positioning.

[0031] By adopting the above technical solution, turning the locking screw unlocks the locking block from the conveyor plate, allowing the conveyor plate to rotate around the locking post. The locking post also guides the movement of the conveyor plate. After adjustment, turning the locking screw presses the locking block against the conveyor plate for positioning, which greatly improves the convenience and accuracy of adjustment, and enhances the quality of the workpiece and the conveying efficiency.

[0032] Optionally, the supporting mechanism includes: A support seat is provided on movable seat one and extends below movable seat two; The support rod is rotatably mounted on the support base via a pivot. Gears are mounted on a rotating shaft; A rack is mounted on the second movable seat and meshes with a gear. When the second movable seat moves upward, it drives the support rod to rotate and press against the lower surface of the workpiece for positioning. When the second movable seat moves downward, it drives the support rod to rotate to the outside of the workpiece to unlock.

[0033] By adopting the above technical solution, the moving seat 2 moves upward to drive the rack to move upward, and the rack moves upward to drive the gear, the rotating shaft and the support rod to rotate, so that the support rod rotates and abuts against the lower surface of the workpiece for positioning; conversely, the moving seat 2 moves downward to drive the support rod to rotate to the outside of the workpiece for unlocking, thereby realizing the support of the workpiece.

[0034] Simultaneously, when the second movable seat moves up and down, it is located above the conveyor belt. If the workpiece falls, it will also fall onto the conveyor belt for cushioning. When the workpiece moves between the two conveyor belts, it is positioned by the cooperation of the support rod and the suction cup, which reduces the risk of workpiece damage and improves the quality of the workpiece and the conveying efficiency.

[0035] Secondly, the workpiece conveying method provided in this application adopts the following technical solution: A workpiece conveying method includes the following steps: Adjustment: The locking component unlocks, and the conveyor plate is moved and / or rotated to adjust the position of multiple adsorption components so that the position of the adsorption components adapts to the workpiece being gripped. After adjustment, the locking component positions the conveyor plate and the multiple adsorption components. At the same time, turning the positioning nut can also adjust the position of a single adsorption component. Workpiece gripping and conveying: Movable seat one drives multiple adsorption components to move above the workpiece, and movable seat two drives multiple adsorption components to move downward; multiple adsorption components grip and adsorb the workpiece, and the adsorption components move upward to drive the workpiece to move, so that the workpiece is moved from one conveyor belt to another. The adsorption components unlock to place the workpiece on the conveyor belt, and then the gripping and conveying of workpieces is repeated to complete the conveying of multiple workpieces.

[0036] By adopting the above technical solution, the locking component unlocks, and the moving and / or rotating conveyor plate is used to adjust the position of multiple adsorption components so that the position of the adsorption components adapts to the workpiece being gripped. After adjustment, the locking component positions the conveyor plate and the multiple adsorption components. At the same time, turning the positioning nut can also adjust the position of a single adsorption component. Moving seat one drives multiple adsorption components to move above the workpiece, and moving seat two drives multiple adsorption components to move downward. Multiple adsorption components grip and adsorb the workpiece. The upward movement of the adsorption components drives the workpiece to move, so that the workpiece is moved from one conveyor belt to another. The adsorption components unlock, allowing the workpiece to be placed on the conveyor belt. Then, the gripping and conveying of workpieces is repeated to complete the conveying of multiple workpieces, thereby improving the workpiece quality and conveying efficiency.

[0037] In summary, this application includes at least one of the following beneficial technical effects: 1. By rotating and moving the conveyor plate, and simultaneously guiding the conveyor plate and multiple adsorption components through the conveying holes, adjustments can be made more quickly and efficiently. This allows the positions and angles of the multiple adsorption components to better adapt to the size and shape of the workpiece, improving the adsorption and positioning effect of the workpiece, saving time, and increasing the quality and conveying efficiency of the workpiece.

[0038] 2. The support mechanism can support and position the workpiece on its lower surface as soon as it separates from the conveyor belt, which is very timely and improves the positioning effect. Compared with the support mechanism, the support mechanism relies on the position of the moving seat to position the workpiece, which can further improve the stability of supporting the workpiece and has a simple structure. Thus, by cooperating with the support mechanism and / or the support mechanism, the quality of the workpiece and the conveying efficiency are improved at the same time. Attached Figure Description

[0041] The following provides a further detailed description of this application.

[0042] This application discloses a workpiece conveying device.

[0043] Example 1, referring to Figure 1 The workpiece conveying device includes a body 1, a first movable seat 11 and a second movable seat 12, and a conveying mechanism 2. The first movable seat 11 is horizontally slidably mounted on the body 1 and vertically downward, while the second movable seat 12 is vertically slidably mounted on the first movable seat 11. The conveying mechanism 2 is used to grip and convey workpieces, transferring them from one conveyor belt 15 to another. The conveying mechanism 2 can adjust the gripping point of the workpiece according to the size and shape of different workpieces, thereby improving the stability of the workpiece conveying process and enhancing the quality and conveying efficiency of the workpieces.

[0044] The driving source for the movement of movable seat 11 and movable seat 2 12 adopts the driving structure in the technology. The driving structure is a nut and screw structure that cooperates with the motor, or a synchronous belt structure that cooperates with the motor. It will not be described in detail here. It is sufficient to realize the horizontal movement of movable seat 11 and the vertical movement of movable seat 2 12.

[0045] Reference Figure 1 and Figure 2The conveying mechanism 2 includes multiple conveying plates 21, multiple locking components 3, and multiple adsorption components 4. There are two conveying plates 21. The number of locking components 3 is the same as that of the conveying plates 21 and they are arranged in a one-to-one correspondence. Multiple adsorption components 4 are provided on each conveying plate 21. Fixed plates 13 extending horizontally to opposite sides of the moving seat 12 are fixedly installed at the bottom of the moving seat 12. The two conveying plates 21 are respectively installed on the two fixed plates 13. Multiple threaded holes 14 are spaced apart along the sliding direction of the moving seat 11.

[0046] One end of the conveyor plate 21 is placed on the fixed plate 13 and locked by the locking component 3. The conveyor plate 21 has a strip-shaped conveying hole 22 along its length. The adsorption component 4 can adjust its position along the conveying hole 22. The locking component 3 is set on the fixed plate 13 and passes through the conveying hole 22. After the locking component 3 is unlocked, the conveyor plate 21 slides and rotates with the locking component 3 through the conveying hole 22. After the position of the conveyor plate 21 is adjusted, the locking component 3 presses against the conveyor plate 21 to position it, thereby adjusting the position of the adsorption component 4. At the same time, the adsorption component 4 can also slide along the conveying hole 22 to adjust its position.

[0047] The locking assembly 3 includes a locking post 31, a locking block 32, and a locking screw 33. The locking post 31 is fixedly installed on the lower surface of the locking block 32, and the diameter of the locking post 31 is less than or equal to the width of the conveying hole 22. The locking block 32 is placed on the conveying plate 21, and the locking post 31 passes vertically through the conveying hole 22. The locking screw 33 passes vertically through the locking block 32 and the locking post 31 and is threadedly connected to the threaded hole 14, so that the locking block 32 presses against the conveying plate 21 for positioning. After the conveying plate 21 is unlocked by turning the locking screw 33, the conveying plate 21 can rotate around the locking post 31 and move along the conveying hole 22. After adjustment, the position of the conveying plate 21 is locked by turning the locking screw 33.

[0048] The adsorption assembly 4 includes a moving column 41, a moving rod 42, a pressing plate 43, a mounting plate 44, an elastic element 45, a suction cup 46, and an air tube 47. The diameter of the moving column 41 is less than or equal to the width of the conveying hole 22. The moving column 41 passes vertically through the conveying hole 22 and moves on the conveying hole 22. The outer wall of the moving column 41 is threaded. At least two positioning nuts 48 are threadedly connected to the moving column 41. The two positioning nuts 48 press against the upper and lower surfaces of the conveying plate 21 for positioning, thereby realizing the positioning of the moving column 41.

[0049] The moving rod 42 is coaxially slidably mounted on the moving column 41, with both ends of the moving rod 42 extending to the upper and lower sides of the conveyor plate 21, respectively. The pressure plate 43 and the mounting plate 44 are coaxially fixedly mounted on the top and bottom ends of the moving rod 42, respectively. The elastic element 45 is a spring, which is sleeved on the moving rod 42 and presses against the bottom end of the moving column 41 and the top end of the mounting plate 44 at both ends, so that the pressure plate 43 presses against the top end of the moving column 41 for positioning. The suction cup 46 is fixedly mounted on the bottom end of the mounting plate 44 and is used to adsorb and position the workpiece. The air pipe 47 is fixedly mounted on the mounting plate 44 located above the suction cup 46. The air pipe 47 is connected to the inside of the suction cup 46 and controls the intake or exhaust of the suction cup 46. The air pipe 47 is controlled by a control box. This is prior art and will not be described in detail.

[0050] The moving seats 11 and 212 work together to drive the conveyor plate 21 and multiple adsorption components 4 to move in both horizontal and vertical directions, causing multiple suction cups 46 to move downwards and press against the workpiece. The suction cups 46 are squeezed, causing the internal air to be discharged through the air pipe 47. After the suction cups 46 are further squeezed, they push the pressure plate 43 upwards, so that the air in the suction cups 46 can be discharged as much as possible. Then the air pipe 47 is closed. The conveyor plate 21 drives multiple moving columns 41 to move upwards, and the moving columns 41 push the pressure plate 43 upwards, so that the multiple suction cups 46 adsorb and grab the workpiece and move it upwards. Then the workpiece is transported to another conveyor belt 15. The conveyor plate 21 and the workpiece move downwards, and then air is introduced through the air pipe 47. Under the action of the elasticity of the suction cups 46 and the thrust of the gas, the workpiece is separated from the suction cups 46, thereby realizing the transport of the workpiece.

[0051] The working principle of this application embodiment is as follows: After the locking component 3 is unlocked, the angle and position of the multiple adsorption components 4 can be adjusted. At the same time, the position of the adsorption components 4 can be further adjusted by turning the positioning nut 48, so that the angle and position of the multiple adsorption components 4 can be adapted to the gripping and conveying of the workpiece, thereby improving the quality of the workpiece and the conveying efficiency.

[0052] The movable seats 11 and 12 work together to drive multiple adsorption components 4 to move, causing multiple suction cups 46 to move downwards and press against the workpiece, thus venting the gas inside the suction cups 46. After the suction cups 46 are further compressed, they push the pressure plate 43 upwards, allowing the air inside the suction cups 46 to be expelled as much as possible. Then the air pipe 47 is closed. The conveyor plate 21 drives multiple movable columns 41 to move upwards, pushing the pressure plate 43 and the workpiece upwards. Then the workpiece is conveyed to another conveyor belt 15. The conveyor plate 21 and the workpiece move downwards, and then air is introduced through the air pipe 47. Under the action of the elasticity of the suction cups 46 and the thrust of the gas, the workpiece is detached from the suction cups 46, thereby realizing the conveying of the workpiece and improving the quality and conveying efficiency of the workpiece.

[0053] Example 2, refer to Figure 1 , Figure 3 and Figure 4The difference between this embodiment and embodiment 1 is that it also includes multiple support mechanisms 6 and / or supporting mechanisms 5. The support mechanisms 6 are set on the moving column 41 and are positioned on the lower surface of the workpiece after the suction cup 46 drives the workpiece to move upward. The number of support mechanisms 6 and moving columns 41 are the same and they are set one-to-one. After the suction cup 46 unlocks the adsorption of the workpiece, the workpiece pushes the support mechanism 6 to unlock the lower surface of the workpiece under the action of gravity and the elasticity of the suction cup 46. The supporting mechanisms 5 are set on the moving seat 11 and the moving seat 22. When the moving seat 22 moves upward, it drives the supporting mechanism 5 to support the lower surface of the workpiece to unlock. When the moving seat 22 moves downward, it first drives the supporting mechanism 5 to rotate to the outside of the workpiece to unlock. The moving seat 22 continues to move downward to complete the conveying of the workpiece.

[0054] Reference Figure 1 , Figure 3 The supporting mechanism 5 includes a supporting seat 51, a supporting rod 52, a gear 53, and a rack 54. The supporting seat 51 is fixedly installed on the bottom of the first movable seat 11 and extends below the second movable seat 12. A horizontally positioned rotating shaft is rotatably installed on one end of the supporting seat 51 near the second movable seat 12. The supporting seat 51 is located outside the conveyor belt 15, reducing the risk of interference between the supporting seat 51 and the conveyor belt 15. One end of the supporting rod 52 is rotatably installed on the supporting seat 51. The gear 53 is installed on the rotating shaft and rotates simultaneously with the rotating shaft. The rack 54 is fixedly installed on the second movable seat 12 and is in a vertical position. The rack 54 meshes with the gear 53.

[0055] After the suction cup 46 grips the workpiece, the moving seat 11 moves upward, driving the support seat 51 to move upward. When the support seat 51 moves upward, it drives the support rod 52 to rotate and approach the workpiece until the support rod 52 abuts against the lower surface of the workpiece for positioning, thereby achieving support and positioning of the workpiece. Then, the moving seat 11 and the moving seat 2 12 move horizontally at the same time. Conversely, when the support seat 51 moves downward, it drives the support rod 52 to rotate to the outside of the workpiece, that is, the support seat 51 rotates back to the initial state, thereby achieving support and positioning of the workpiece. When the workpiece is transported between the two conveyor belts 15, the support rod 52 and multiple suction cups 46 cooperate to position the workpiece, improving the quality of the workpiece and the conveying efficiency.

[0056] Reference Figure 1 and Figure 4 The support mechanism 6 includes a support base 61, a slide rail 62, a support rod 63, a support block 64, an elastic element 65, a push rod 66 and a push block 67, and an elastic plug-in assembly 7. The support base 61 is mounted on the moving column 41 via a connecting assembly, and the support base 61 is located outside the workpiece. The connecting assembly includes a connecting ring 81, a connecting rod 82, an adjusting rod 83, and a connecting screw 84. The connecting ring 81 is coaxially sleeved on the moving column 41, and the positioning nut 48 pushes the connecting ring 81 to press against the conveyor plate 21 for positioning.

[0057] The connecting rod 82 is fixedly installed on the outer wall of the connecting ring 81 and is arranged radially along the connecting ring 81. The adjusting rod 83 is fixedly installed on the side wall of the support base 61. The length directions of the connecting rod 82 and the adjusting rod 83 are parallel, and the adjusting rod 83 slides through the connecting rod 82. The connecting screw 84 is threadedly connected to the connecting rod 82 and presses against the adjusting rod 83 for positioning. Tightening the connecting screw 84 unlocks the position, which allows the position of the support base 61 to be adjusted. After adjustment, tightening the connecting screw 84 presses against the adjusting rod 83 for positioning. After tightening the positioning nut 48 unlocks the position, the angle of the support base 61 can be rotated to adjust the position and angle of the support base 61.

[0058] Reference Figure 1 , Figure 4 and Figure 5 The support base 61 is vertical. The slide rail 62 is fixedly installed on the side wall of the support base 61 and is inclined downward. The bottom end of the slide rail 62 is set towards the side close to the suction cup 46, and a slider 621 is slidably set along the inclined direction of the slide rail 62, with the slider 621 extending to the outside of the slide rail 62. The top end of the support rod 63 is fixedly installed on the side wall of the slider 621 and is vertically downward. The support block 64 is fixedly installed on the bottom end of the support rod 63 by screws, and one end of the support block 64 extends to the side close to the suction cup 46 and has a support surface 641. The support surface 641 penetrates the upper and lower surfaces of the support block 64, making it easy to extend under the workpiece. At the same time, the angle of the support block 64 can be adjusted after loosening the screws, so that the support block 64 can better extend under the workpiece and lift the workpiece upward.

[0059] The elastic element 65 is a spring, and both ends of the elastic element 65 are fixedly connected to the top of the slide rail 62 and the upper surface of the slider 621; the push rod 66 is vertically slidably installed on the side wall of the support base 61 and one end extends to the side near the support rod 63, and the push rod 66 is radially arranged along the pressure plate 43 and detachably connected to the pressure plate 43; the push block 67 is fixedly installed on the top of the support rod 63 and located on the side wall near the push rod 66, and the push block 67 and the push rod 66 have inclined and mutually fitting push surfaces 68 at opposite ends, and the inclination direction of the push surface 68 is not parallel to the inclination direction of the slide rail 62.

[0060] After the pressure plate 43 moves upward, driving the push rod 66 to move upward, the support rod 63 and the support block 64 tilt and move downward under the action of elastic force. In the initial state, the pressure plate 43 abuts against the moving column 41, and the push surfaces 68 on the push block 67 and the push rod 66 fit together to position the support rod 63 and the support block 64, so that the workpiece is located between multiple support blocks 64.

[0061] The elastic plug-in assembly 7 is mounted on the support base 61. After the pressure plate 43 moves upward away from the moving column 41, the elastic plug-in assembly 7 is plugged into and positioned in the gap between the pressure plate 43 and the moving column 41 under the pushing action of the support rod 63. The elastic plug-in assembly 7 includes a plug-in rod 71, a mounting block 72, and an elastic pusher 73. The plug-in rod 71 is slidably mounted on the support base 61 along the length of the pusher rod 66, and the plug-in rod 71 is located on the side of the support rod 63 near the pressure plate 43. The mounting block 72 is vertically slidably mounted on the side wall of the support rod 63 near the plug-in rod 71 and is located below the pusher block 67. The elastic pusher 73 is a spring, and its two ends are fixedly connected to the side walls of the plug-in rod 71 and the mounting block 72, respectively. Multiple ball bearings are rotatably mounted on the plug-in rod 71, which are supported and positioned on the pressure plate 43 and the moving column 41. The plug-in rod 71 has a plug-in surface 74 for easy plugging and installation between them.

[0062] The downward movement of the moving column 41 causes multiple suction cups 46 to press against the workpiece, positioning the workpiece between multiple support blocks 64. The moving column 41 continues to move downward, pushing the pressure plate 43 upward. The upward movement of the pressure plate 43 drives the push rod 66 upward away from the push block 67, causing the two push surfaces 68 to disengage. The slider 621, support rod 63, and support block 64 all tilt downward under the action of the elastic element 65, causing the support block 64 to move downward and approach the workpiece until the support block 64 abuts against the side wall of the workpiece and the conveyor belt 15 for positioning. During the downward movement of the support rod 63, the mounting block 72 is driven to approach the pressure plate 43. The mounting block 72 pushes the insertion rod 71 to approach the pressure plate 43 through the elastic push element 73, causing the balls on the insertion rod 71 to press against the pressure plate 43 and the moving column 41 for positioning, preventing the pressure plate 43 from moving back.

[0063] The upward movement of the moving column 41 drives the pressure plate 43 and multiple suction cups 46 to move upward. The suction cups 46 drive the workpiece to detach from the conveyor belt 15. At the same time, the upward movement of the pressure plate 43 drives the support base 61, the push rod 66, and the slide 62 to move upward away from the push block 67. However, due to the downward pushing force of the elastic element 65, the slider 621 slides downward on the slide 62 at an angle. The sliding of the slider 621 drives the support rod 63, the support block 64, and the push block 67 to move downward and approach the workpiece at the same time, so that the support block 64 presses against the lower surface of the workpiece for positioning. This continues until the two pushing surfaces 68 on the push block 67 and the push rod 66 abut against each other for positioning, and / or the side wall of the workpiece abuts against the support rod 63 for positioning, so that the multiple suction cups 46 and the multiple support blocks 64 cooperate to position the workpiece. At the same time, when the support rod 63 moves downward, it continues to push the insertion rod 71 to move.

[0064] After the workpiece is conveyed onto another conveyor belt 15, the multiple suction cups 46 release their force on the workpiece. Under the action of gravity and the support surface 641, the workpiece pushes the support block 64 upward and away from the workpiece. At the same time, when the deformed suction cups 46 recover, they generate a downward pushing force on the workpiece. When the support rod 63 moves upward, it pulls the plug rod 71 to disengage from the pressure plate 43 and the moving column 41. Under the pushing force of the elastic element 45, the pressure plate 43 moves closer to the moving column 41. The moving column 41 moves and drives the push rod 66 to push the push block 67 to tilt upward and away from the workpiece. This works together to make the multiple push rods 66 and the multiple support blocks 64 return to their original positions, thereby facilitating the continued conveying and positioning of the next workpiece and improving the quality and conveying efficiency of the workpiece.

[0065] The working principle of this application embodiment is as follows: The suction cup 46 grips the workpiece, and the moving seat 11 moves upward to drive the support rod 52 to abut against the lower surface of the workpiece for positioning, thereby achieving support and positioning of the workpiece; conversely, when the support seat 51 moves downward, it drives the support rod 52 to rotate to the outside of the workpiece to unlock, thereby achieving support and positioning of the workpiece, improving the quality of the workpiece and the conveying efficiency.

[0066] The downward movement of the moving column 41 causes multiple suction cups 46 to press against the workpiece. The moving column 41 continues to move downward, pushing the pressing plate 43 and the pushing rod 66 upward away from the pushing block 67, causing the support block 64 to move downward and approach the workpiece, until the support block 64 abuts against the side wall of the workpiece and the conveyor belt 15 for positioning. At the same time, the support rod 63 moves downward, pushing the plug-in rod 71 to press against the pressing plate 43 and the moving column 41 for positioning.

[0067] The moving column 41 moves upward to drive the workpiece to disengage from the conveyor belt 15, while the slider 621 slides downward at an angle on the slide rail 62, causing the support block 64 to press against the lower surface of the workpiece for positioning, until the two pushing surfaces 68 on the pushing block 67 and the pushing rod 66 continue to abut against each other for positioning, and / or the side wall of the workpiece abuts against the support rod 63 for positioning, so that the multiple suction cups 46 and the multiple support blocks 64 cooperate to position the workpiece.

[0068] After the workpiece is conveyed onto another conveyor belt 15, the multiple suction cups 46 release their force on the workpiece. Under the action of gravity and the support surface 641, the workpiece pushes the support block 64 upward and away from the workpiece. At the same time, when the deformed suction cups 46 recover, they generate a downward pushing force on the workpiece. When the support rod 63 moves upward, it pulls the plug rod 71 to disengage from the pressure plate 43 and the moving column 41. The pressure plate 43 moves closer to the moving column 41, and the moving column 41 moves to push the push block 67 back. In this way, the multiple push rods 66 and the multiple support blocks 64 move back to their original positions, which facilitates the positioning of the next workpiece and improves the quality of the workpiece and the conveying efficiency.

[0069] This application discloses a workpiece conveying method.

[0070] Reference Figures 1-2 The workpiece conveying method includes the following steps: Adjustment: Locking component 3 is unlocked, and the conveyor plate 21 is moved and / or rotated to adjust the position of multiple adsorption components 4 so that the position of adsorption components 4 is adapted to the workpiece being gripped. After adjustment, locking component 3 positions the conveyor plate 21 and multiple adsorption components 4. At the same time, turning the positioning nut 48 can also adjust the position of a single adsorption component 4.

[0071] Grabbing and conveying workpieces: Movable seat 11 drives multiple adsorption components 4 to move above the workpiece, and movable seat 2 12 drives multiple adsorption components 4 to move downward; multiple adsorption components 4 grab and adsorb the workpiece, and the adsorption components 4 move upward to drive the workpiece to move, so that the workpiece is moved from conveyor belt 15 to another conveyor belt 15. The adsorption components 4 unlock to place the workpiece on the conveyor belt 15, and then the grabbing and conveying of workpieces is repeated to complete the conveying of multiple workpieces.
