[0002] Currently, automated production lines, with their advantages of high efficiency and low cost, have become the mainstream production mode in many manufacturing sectors such as automobiles and electronics. During product processing, because automobiles and electronic devices include many small parts, to ensure processing accuracy, workers need to manually place these small parts onto the production line, which then completes the processing.

[0003] However, manual loading and unloading by workers is time-consuming and labor-intensive, and is also easily affected by human operating experience, making it impossible to meet the efficiency requirements of automated production lines, thus reducing product processing efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide an automatic loading and unloading device to solve the problem of low efficiency of workers loading and unloading small workpieces in the prior art.

[0005] To achieve the above objectives, this utility model provides an automatic loading and unloading device, comprising: a frame; a loading assembly including a bearing structure, the bearing structure being adjustablely positioned on the frame, the bearing structure being used to support a pallet structure, the pallet structure being used to support a workpiece; a clamping assembly, positioned on the frame, the clamping assembly including an abutment structure and at least two opposing clamping structures, the at least two clamping structures surrounding each other to form a clamping space, the size of the clamping space being adjustablely positioned to clamp the pallet structure, the abutment structure being adjustablely positioned on the clamping structure to avoid the pallet structure or to abut against the end of the pallet structure in the clamping space away from the bearing structure; and an unloading assembly including an adsorption structure, the adsorption structure being adjustablely positioned on the frame, the adsorption structure being used to adsorb the workpiece located in the clamping space.

[0006] Furthermore, there are multiple feeding components, which are spaced apart on the frame along a first preset direction. The clamping components also include a clamping sliding structure, which includes a clamping slide rail and a clamping slider. The clamping slide rail and the clamping slider are slidably engaged. The clamping slide rail is disposed on the frame and extends along the first preset direction. The clamping slider is connected to each clamping structure.

[0007] Furthermore, the clamping assembly is located above the feeding assembly, which also includes: a support structure connected to the load-bearing structure; and a feeding drive structure connected to the support structure to drive the support structure to move toward or away from the clamping assembly.

[0008] Furthermore, the feeding assembly also includes a feeding sliding structure, including a feeding slide rail and a feeding slider, the feeding slide rail and the feeding slider slidingly engaging, the feeding slide rail being disposed on the support structure and extending along a second preset direction, and the feeding slider being connected to the bearing structure; wherein, the second preset direction is set at an angle to the first preset direction.

[0009] Furthermore, the feeding assembly is located above the clamping assembly, and the feeding assembly also includes: a feeding drive structure, which is driven to connect with the adsorption structure to drive the adsorption structure to rotate along a preset axis and move toward or away from the clamping assembly; a feeding sliding structure, including a feeding slide rail and a feeding slider, which are slidably engaged. The feeding slide rail is mounted on the frame and extends along a third preset direction, and the feeding slider is connected to the feeding drive structure; wherein, the third preset direction is set at an angle to the first preset direction.

[0010] Furthermore, the feeding assembly also includes: a feeding fixing structure, which is mounted on the frame; a first transmission structure, including a nut structure and a lead screw, wherein the nut structure is fixedly mounted on the feeding fixing structure and has a threaded hole, one end of the lead screw is connected to the support structure, and the other end of the lead screw passes through the threaded hole and is connected to the feeding drive structure, and the lead screw is threadedly engaged with the wall of the threaded hole; wherein, during the process of the feeding drive structure driving the lead screw to rotate, the lead screw moves along the extension direction of the threaded hole.

[0011] Furthermore, the feeding assembly also includes: a feeding mounting structure connected to the end of the lead screw away from the support structure; a second transmission structure including a driving wheel, a driven wheel, and a transmission belt, wherein the driving wheel is sleeved on the output shaft of the feeding drive structure, the driven wheel is sleeved on the lead screw, and the transmission belt is sleeved on the driving wheel and the driven wheel; wherein, during the process of the feeding drive structure driving the driving wheel to rotate, the driving wheel drives the lead screw to rotate through the driven wheel.

[0012] Furthermore, the feeding assembly also includes: a feeding limit structure, which is disposed on the feeding mounting structure near the feeding fixing structure; and a feeding limit detection structure, which is disposed on the feeding fixing structure near the feeding mounting structure. The feeding limit detection structure is used to detect the position of the feeding limit structure so as to control the operation of the feeding drive structure according to the detection result of the feeding limit detection structure.

[0013] Furthermore, the clamping assembly also includes: a clamping fixing structure disposed on the clamping slider; a clamping driving structure disposed on the clamping fixing structure, the clamping driving structure being driven to at least one clamping structure to drive the clamping structure to move toward or away from another clamping structure to adjust the size of the clamping space; and an abutment driving structure being driven to abutment structure to drive the abutment structure to move toward or away from the tray structure within the clamping space.

[0014] Furthermore, the load-bearing structure has a first magnetic absorbing element, and the supporting structure has a second magnetic absorbing element, with the first magnetic absorbing element and the second magnetic absorbing element being magnetically connected.

[0015] According to the technical solution of this utility model, the loading component of the automatic loading and unloading device includes a supporting structure, which is adjustablely positioned on the frame and supports a pallet structure, which in turn supports a workpiece. A clamping component is mounted on the frame and includes an abutment structure and at least two opposing clamping structures. A clamping space is formed between the at least two clamping structures, the size of which is adjustable for clamping the pallet structure. The abutment structure is adjustablely positioned on the clamping structure to avoid the pallet structure or abut against the end of the pallet structure within the clamping space furthest from the supporting structure. The unloading component includes an adsorption structure, which is adjustablely positioned on the frame and is used to adsorb workpieces located within the clamping space. In this way, when workers need to load or unload workpieces, they only need to place the workpiece on the pallet structure. The supporting structure then moves the pallet structure to allow the two clamping structures of the clamping assembly to hold it. Once the two clamping structures have secured the pallet, the suction structure of the unloading assembly picks up the workpiece from the pallet and places it on the production line. This reduces manual operation steps, lowers the difficulty and labor intensity for workers, and improves work efficiency, thus solving the problem of low workpiece loading and unloading efficiency in existing technologies. Simultaneously, the abutment structure's design ensures that it abuts against the pallet structure when the suction structure is holding the workpiece, preventing the pallet structure from shifting due to excessive suction force. This guarantees the reliability of the suction structure and the unloading assembly's unloading reliability. Furthermore, the adjustable position of the supporting structure expands its range of motion, making it easier for workers to place the pallet on it and for the clamping assembly to hold it. This improves the coordination between the loading and clamping assemblies, increasing the efficiency of the automatic loading and unloading device. Meanwhile, the adjustable position of the adsorption structure allows it to cooperate with the clamping components, expanding the range of workpieces that the adsorption structure can adsorb, thus improving the versatility of the adsorption structure and the automatic loading and unloading device. Furthermore, the adjustable clamping space allows the clamping components to adapt to pallet structures of different sizes, further enhancing the clamping versatility of the clamping components and the automatic loading and unloading device.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0039] To address the problem of low efficiency in loading and unloading small workpieces by workers in existing technologies, this application provides an automatic loading and unloading device.

[0040] like Figures 1 to 13As shown, the automatic loading and unloading device includes a frame 10, a loading assembly 20, a clamping assembly 30, and an unloading assembly 40. The loading assembly 20 includes a support structure 21, which is adjustablely positioned on the frame 10. The support structure 21 supports a pallet structure 1, which supports a workpiece. The clamping assembly 30 is mounted on the frame 10 and includes an abutment structure 31 and at least two opposing clamping structures 32. The at least two clamping structures 32 surround each other to form a clamping space 321. The size of the clamping space 321 is adjustable for clamping the pallet structure 1. The abutment structure 31 is adjustablely positioned on the clamping structures 32 to avoid the pallet structure 1 or to abut against the end of the pallet structure 1 in the clamping space 321 away from the support structure 21. The unloading assembly 40 includes an adsorption structure 41, which is adjustablely positioned on the frame 10. The adsorption structure 41 is used to adsorb workpieces located in the clamping space 321.

[0041] Applying the technical solution of this embodiment, the loading component 20 of the automatic loading and unloading device includes a supporting structure 21, which is adjustablely positioned on the frame 10. The supporting structure 21 supports the pallet structure 1, which supports the workpiece. A clamping component 30 is mounted on the frame 10 and includes an abutment structure 31 and at least two opposing clamping structures 32. A clamping space 321 is formed between the at least two clamping structures 32. The size of the clamping space 321 is adjustable for clamping the pallet structure 1. The abutment structure 31 is adjustablely positioned on the clamping structures 32 to avoid the pallet structure 1 or abut against the end of the pallet structure 1 in the clamping space 321 away from the supporting structure 21. The unloading component 40 includes an adsorption structure 41, which is adjustablely positioned on the frame 10. The adsorption structure 41 is used to adsorb the workpiece located in the clamping space 321. In this way, when workers need to load or unload workpieces, they only need to place the workpiece on the tray structure 1. Then, the supporting structure 21 can move the tray structure 1 to facilitate the clamping structure 32 of the clamping assembly 30 to clamp the tray structure 1. After the two clamping structures 32 clamp the tray structure 1, the suction structure 41 of the unloading assembly 40 will pick up the workpiece on the tray structure 1 and place it on the production line. This reduces the number of manual operation steps for workers, lowers the difficulty and labor intensity of operation, and improves the work efficiency of workers. This solves the problem of low efficiency in loading and unloading workpieces in the prior art. At the same time, the setting of the abutment structure 31 allows it to abut against the tray structure 1 when the suction structure 41 is absorbing the workpiece. This avoids the phenomenon that the suction structure 41 will absorb the tray structure 1 along with the workpiece when the suction force of the suction structure 41 is too large, which would cause the tray structure 1 to shift. This ensures the suction reliability of the suction structure 41 and the unloading reliability of the unloading assembly 40. Meanwhile, the adjustable position of the supporting structure 21 expands its range of motion, facilitating the placement of the pallet structure 1 on it and the clamping assembly 30's gripping of the pallet structure 1. This improves the coordination between the loading assembly 20 and the clamping assembly 30, thereby increasing the efficiency of the automatic loading and unloading device. Similarly, the adjustable position of the adsorption structure 41 allows it to work in conjunction with the clamping assembly 30, expanding the range of workpieces that the adsorption structure 41 can adsorb, enhancing its versatility and the overall versatility of the automatic loading and unloading device. Furthermore, the adjustable clamping space 321 allows the clamping assembly 30 to adapt to pallet structures 1 of different sizes, improving its clamping versatility and the overall versatility of the automatic loading and unloading device.

[0042] In this embodiment, the tray structure 1 is a tray.

[0043] Specifically, the upper surface of the tray is rectangular and has multiple receiving recesses 101. These recesses are divided into multiple groups, and each group includes multiple receiving recesses 101. The groups of receiving recesses 101 are spaced apart along the width of the upper surface of the tray, and the multiple receiving recesses 101 in each group are spaced apart along the length of the upper surface of the tray. This arrangement increases the number of workpieces that the tray structure 1 can accommodate, thus improving its accommodating range.

[0044] In this embodiment, the adsorption structure 41 is a suction cup.

[0045] In this embodiment, the frame 10 is also equipped with casters and feet. The casters are rotatably mounted on the frame 10. When the operator pushes the frame 10 to the production line position, the operator flips the casters so that the feet contact the ground and the casters do not contact the ground, so as to ensure the structural stability of the frame 10.

[0046] In this embodiment, two clamping structures 32 are provided.

[0047] It should be noted that the number of clamping structures 32 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of clamping structures 32 can be three, four, six, eight, or more.

[0048] In this embodiment, the pallet structure 1 is provided with a positioning pin and the bearing structure 21 is provided with a positioning hole. The operator inserts the positioning pin into the positioning hole to realize the connection between the pallet structure 1 and the bearing structure 21, which ensures the stability of the pallet structure 1 and the bearing reliability of the bearing structure 21.

[0049] In this embodiment, auxiliary baffles are also provided at both ends of the clamping structure 32. The auxiliary baffles are set at an angle to the clamping structure 32 so that after the two clamping structures 32 clamp the two sides of the tray structure 1, the other sides of the tray structure 1 are clamped, which increases the clamping stability of the clamping assembly 30. At the same time, the clamping structure 32 and the auxiliary baffles can be combined to form a shape that matches the outer peripheral surface of the tray structure 1, further ensuring the clamping stability of the clamping assembly 30.

[0050] like Figures 1 to 3As shown, there are multiple feeding components 20, which are spaced apart on the frame 10 along a first preset direction. The clamping component 30 also includes a clamping sliding structure 33. The clamping sliding structure 33 includes a clamping slide rail and a clamping slider, which slide together. The clamping slide rail is located on the frame 10 and extends along the first preset direction. The clamping slider is connected to each clamping structure 32. In this way, the arrangement of multiple feeding components 20 allows multiple bearing structures 21 to carry more workpieces and wait for two clamping structures 32 to clamp the tray structure 1. The two clamping structures 32 slide along the first preset direction through the clamping sliding structure 33, so that the two clamping structures 32 first clamp the tray structure 1 on one of the feeding components 20 and wait for the adsorption structure 41 to adsorb the workpiece. After the adsorption structure 41 adsorbs the workpiece on the tray structure 1, the clamping structure 32 no longer clamps the tray structure 1, and the tray structure 1 waits to accommodate new workpieces. Subsequently, the two clamping structures 32 slide to the position of another feeding component 20 to clamp the tray structure 1, and wait for the adsorption structure 41 to adsorb the workpiece. The above arrangement enables the clamping structure 32 to continuously clamp new tray structures 1, and also enables the adsorption structure 41 to continuously adsorb workpieces and send them to the production line, ensuring the processing continuity of the production line and improving the work efficiency of the staff.

[0051] In this embodiment, two feeding components 20 are provided.

[0052] It should be noted that the number of feeding components 20 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of feeding components 20 can be three, four, six, eight, or more.

[0053] In this embodiment, the clamping sliding structure 33 is a linear module.

[0054] like Figures 1 to 4As shown, the clamping assembly 30 is located above the loading assembly 20. The loading assembly 20 also includes a support structure 22 and a loading drive structure 23. The support structure 22 is connected to the bearing structure 21. The loading drive structure 23 is driven by the support structure 22 to drive the support structure 22 to move toward or away from the clamping assembly 30. In this way, the loading drive structure 23 drives the support structure 22 to move, so that the support structure 22 can drive the bearing structure 21 to move toward or away from the loading fixing structure 25, thereby enabling the bearing structure 21 to drive the pallet structure 1 and the workpiece to move toward the clamping assembly 30. This is beneficial for the clamping assembly 30 to clamp the pallet structure 1 and ensures the reliability of the cooperation between the bearing structure 21 and the clamping structure 32. At the same time, the arrangement of the clamping assembly 30 above the loading assembly 20 can optimize the structural layout of the clamping assembly 30 and the loading assembly 20, save the space occupied by the clamping assembly 30 and the loading assembly 20, and make the structure of the automatic loading and unloading device more compact, realizing the miniaturization design of the automatic loading and unloading device.

[0055] like Figure 3 As shown, the feeding assembly 20 also includes a feeding sliding structure 24. The feeding sliding structure 24 includes a feeding slide rail and a feeding slider, which slide in cooperation. The feeding slide rail is mounted on the support structure 22 and extends along a second preset direction, while the feeding slider is connected to the bearing structure 21. The second preset direction forms an angle with the first preset direction. In this way, the feeding assembly 20, through the feeding sliding structure 24, allows the bearing structure 21 to slide relative to the support structure 22, further expanding the range of motion of the bearing structure 21. This allows the bearing structure 21 to move both relative to and follow the support structure 22, improving its versatility. Simultaneously, the angle between the second and first preset directions enhances the processing flexibility of the operator, making the processing positions of the feeding slide rail more diverse.

[0056] In this embodiment, a handle is provided on the supporting structure 21. By pulling the handle, the operator can slide the supporting structure 21 relative to the supporting structure 22, making it convenient for the operator to pull out the supporting structure 21 and place the pallet structure 1 on it, and then place the workpiece on the pallet structure 1, further improving the operator's work efficiency. At the same time, the sliding cooperation between the feeding slide rail and the feeding slider can reduce friction and ensure the smooth sliding of the supporting structure 21.

[0057] In this embodiment, the angle between the first preset direction and the second preset direction is set at 90°.

[0058] It should be noted that the angle between the first preset direction and the second preset direction is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the angle between the first preset direction and the second preset direction is 70°, 85°, 95°, 110°, or 135°, etc.

[0059] like Figure 1 , Figures 7 to 13 As shown, the unloading component 40 is located above the clamping component 30. The unloading component 40 also includes an unloading drive structure 42 and an unloading sliding structure 43. The unloading drive structure 42 is driven to connect with the adsorption structure 41, driving the adsorption structure 41 to rotate along a preset axis and move towards or away from the clamping component 30. The unloading sliding structure 43 includes an unloading slide rail and an unloading slider, which slide together. The unloading slide rail is mounted on the frame 10 and extends along a third preset direction, while the unloading slider is connected to the unloading drive structure 42. The third preset direction forms an angle with the first preset direction. In this way, the unloading component 40 is positioned above the clamping component 30, so that the loading component 20, clamping component 30, and loading component 20 are arranged from bottom to top, further optimizing the structural layout of the automatic loading and unloading device, saving space occupied by the loading component 20, clamping component 30, and loading component 20, making the structure of the automatic loading and unloading device more compact, and realizing the miniaturization design of the automatic loading and unloading device. Meanwhile, the unloading component 40 drives the adsorption structure 41 toward the clamping component 30 via the unloading drive structure 42 to adsorb the workpiece on the clamping component 30, and drives the adsorption structure 41 to rotate, allowing the adsorption structure 41 to adjust its angle, thus achieving adsorption flexibility and ensuring the accuracy of workpiece unloading. Simultaneously, the unloading component 40, through the unloading sliding structure 43, enables the adsorption structure 41 to move along a third preset direction, expanding the adsorption range of the adsorption structure 41 and improving its adsorption versatility. Furthermore, the unloading sliding structure 43 can cooperate with the clamping sliding structure 33 of the clamping component 30, allowing the clamping component 30 to adjust the position of the tray structure 1 to further expand the adsorption range of the adsorption structure 41, further improving the versatility of the automatic unloading device. Additionally, the angled arrangement between the third preset direction and the first preset direction improves the processing flexibility of the operator, making the processing positions of the unloading slide rail more diverse.

[0060] In this embodiment, the adsorption drive structure is a lifting and rotating cylinder, and the adsorption structure 41 is disposed on the output shaft of the lifting and rotating cylinder. The lifting and rotating cylinder drives the adsorption structure 41 to lift and rotate.

[0061] Specifically, the preset axis is the central axis of the output shaft of the lifting and rotating cylinder.

[0062] In this embodiment, the feeding assembly 40 further includes an adsorption mounting plate, which is connected to the output shaft of the lifting and rotating cylinder. The axis of symmetry of the adsorption mounting plate coincides with a preset axis. Six adsorption structures 41 are provided, divided into two groups. The two groups of adsorption structures 41 are spaced apart along the width direction of the adsorption mounting plate. Each group of adsorption structures 41 includes three adsorption structures 41, which are spaced apart along the length direction of the adsorption mounting plate.

[0063] In this embodiment, the material feeding sliding structure 43 is a linear module.

[0064] In this embodiment, the angle between the first preset direction and the third preset direction is set at 90°.

[0065] It should be noted that the angle between the first preset direction and the third preset direction is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the angle between the first preset direction and the third preset direction is 70°, 85°, 95°, 110°, or 135°, etc.

[0066] In this embodiment, the frame 10 is arranged in a frame structure, and the frame is arranged in a cuboid shape, such as... Figure 1 As shown, the first preset direction is the length direction of the frame, the second preset direction is the width direction of the frame, and the third preset direction is parallel to the second preset direction. The feeding assembly 20, the clamping assembly 30, and the unloading assembly 40 are arranged at intervals along the height direction of the frame.

[0067] like Figures 2 to 4As shown, the feeding assembly 20 also includes a feeding fixing structure 25 and a first transmission structure 26. The feeding fixing structure 25 is mounted on the frame 10. The first transmission structure 26 includes a nut structure 261 and a lead screw 262. The nut structure 261 is fixedly mounted on the feeding fixing structure 25 and has a threaded hole. One end of the lead screw 262 is connected to the support structure 22, and the other end of the lead screw 262 passes through the threaded hole and is connected to the feeding drive structure 23. The lead screw 262 is threadedly engaged with the wall of the threaded hole. During the rotation of the lead screw 262 driven by the feeding drive structure 23, the lead screw 262 moves along the extension direction of the threaded hole. Thus, the feeding assembly 20 achieves connection with the frame 10 through the feeding fixing structure 25. Meanwhile, during the rotation of the lead screw 262 driven by the feeding drive structure 23, the nut structure 261 is fixedly connected to the feeding fixing structure 25, thus fixing the nut structure 261. The lead screw 262 moves along the extension direction of the threaded hole of the nut structure 261, enabling the lead screw 262 to drive both the support structure 22 and the feeding drive structure 23 towards the clamping assembly 30, thereby ensuring the reliability of the movement of the support structure 22. Furthermore, compared to the method where the lead screw 262 rotates and the nut structure 261 drives the support structure 22 to move along the extension direction of the lead screw 262, the method of fixing the nut structure 261 and driving the support structure 22 to move not only improves the support stability of the support structure 22 but also reduces the auxiliary structures that restrict the rotation of the nut, lowering production costs, improving the economy of the feeding assembly 20, reducing the processing difficulty for workers, and increasing their processing efficiency.

[0068] In this embodiment, the feeding drive structure 23 is a servo motor.

[0069] In this embodiment, the feeding installation structure 27, the feeding fixing structure 25, the supporting structure 22, and the load-bearing structure 21 are all plate-shaped.

[0070] In this embodiment, the feeding assembly 20 further includes a guide structure. One end of the guide structure is connected to the feeding mounting structure 27, and the other end passes through the feeding fixing structure 25 and is connected to the support structure 22. Two guide structures are configured, with the lead screw 262 located between them. This allows the guide structures to assist the lead screw 262 in driving the support structure 22 and the feeding mounting structure 27, balancing the force on the lead screw 262, improving its support stability, and enhancing the feeding stability and reliability of the feeding assembly 20. Simultaneously, the guide structures guide the movement of the lead screw 262, preventing deviation during its operation and further improving the operational reliability of the feeding assembly 20.

[0071] Specifically, a bearing is installed on the feeding and fixing structure 25. The bearing is sleeved on the guide structure to assist the sliding of the guide structure and ensure the smooth operation of the guide structure.

[0072] like Figures 2 to 4 As shown, the feeding assembly 20 also includes a feeding mounting structure 27 and a second transmission structure 28. The feeding mounting structure 27 is connected to the end of the lead screw 262 away from the support structure 22. The second transmission structure 28 includes a driving wheel 281, a driven wheel 282, and a transmission belt 283. The driving wheel 281 is sleeved on the output shaft of the feeding drive structure 23, the driven wheel 282 is sleeved on the lead screw 262, and the transmission belt 283 is sleeved on the driving wheel 281 and the driven wheel 282. During the process of the feeding drive structure 23 driving the driving wheel 281 to rotate, the driving wheel 281 drives the lead screw 262 to rotate via the driven wheel 282. In this way, the feeding assembly 20 achieves the installation of the second transmission structure 28 and the feeding drive structure 23 through the feeding mounting structure 27, ensuring the installation reliability of the feeding drive structure 23 and the second transmission structure 28. Meanwhile, the feeding drive structure 23 drives the lead screw 262 through the second transmission structure 28, and increases the torque through the driving wheel 281 and the driven wheel 282, so that the feeding drive structure 23 can ensure the stability of the driving force even when driving multiple workpieces, thus improving the driving reliability of the feeding drive structure 23.

[0073] like Figure 3 As shown, the feeding assembly 20 also includes a feeding limiting structure 29 and a feeding limiting detection structure 210. The feeding limiting structure 29 is disposed on the end of the feeding mounting structure 27 near the feeding fixing structure 25. The feeding limiting detection structure 210 is disposed on the end of the feeding fixing structure 25 near the feeding mounting structure 27. The feeding limiting detection structure 210 is used to detect the position of the feeding limiting structure 29, and controls the operation of the feeding drive structure 23 according to the detection result of the feeding limiting detection structure 210. In this way, the feeding limiting detection structure 210 disposed on the feeding fixing structure 25 can detect the position of the feeding limiting structure 29. When the feeding limiting structure 29 moves to the position of the feeding fixing structure 25, the feeding limiting detection structure 210 controls the feeding drive structure 23 to stop driving, so as to avoid the collision between the feeding mounting structure 27 and the feeding fixing structure 25, ensuring the structural stability of the feeding assembly 20 and extending the service life of the feeding assembly 20.

[0074] In this embodiment, the feeding limit detection structure 210 is a linear position sensor, and the feeding limit structure 29 is a magnetic induction sheet or a metal induction sheet.

[0075] In this embodiment, a magnetic induction sheet or a metal induction sheet is also provided on the support structure 22, and a linear position sensor is also provided at one end of the feeding and fixing structure 25 near the support structure 22 to detect whether a tray is being carried on the bearing structure 21.

[0076] like Figure 5 and Figure 6 As shown, the clamping assembly 30 also includes a clamping fixing structure 34, a clamping driving structure 35, and an abutment driving structure 36. The clamping fixing structure 34 is disposed on the clamping slider. The clamping driving structure 35 is disposed on the clamping fixing structure 34 and is drivenly connected to at least one clamping structure 32 to drive the clamping structure 32 to move toward or away from another clamping structure 32, thereby adjusting the size of the clamping space 321. The abutment driving structure 36 is drivenly connected to an abutment structure 31 to drive the abutment structure 31 to move toward or away from the tray structure 1 within the clamping space 321. In this way, the clamping assembly 30 achieves a connection with the clamping slider through the clamping fixing structure 34, enabling the clamping slider to slide along the clamping driving structure 35 and the clamping structure 32 via the clamping fixing structure 34, ensuring the sliding stability of the clamping driving structure 35 and the clamping structure 32. Meanwhile, the clamping drive structure 35 drives the clamping structure 32 to adjust the size of the clamping space 321, ensuring the clamping reliability of the clamping space 321, thereby ensuring the clamping reliability of the clamping assembly 30. At the same time, the abutment drive structure 36 drives the abutment structure 31 to move, realizing the automated operation of the abutment structure 31 and ensuring the operational reliability and accuracy of the abutment structure 31.

[0077] In this embodiment, both the clamping drive structure 35 and the abutment drive structure 36 are cylinders.

[0078] In this embodiment, two clamping drive structures 35 are provided. The two clamping drive structures 35 are respectively connected to the two clamping structures 32 to drive the two clamping structures 32 to move closer to or further away from each other.

[0079] It should be noted that the number of clamping drive structures 35 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of clamping drive structures 35 can be three, four, six, eight, or more.

[0080] In this embodiment, four abutment drive structures 36 are provided. The four abutment drive structures 36 are divided into two groups of abutment drive structures 36. The two groups of abutment drive structures 36 are arranged opposite to each other on the clamping structure 32. Two abutment drive structures 36 in each group are located on both sides of the clamping drive structure 35 and jointly drive the abutment structure 31 to move, thereby improving the operational stability of the abutment structure 31.

[0081] In this embodiment, a through-beam photoelectric sensor is also provided on the clamping and fixing structure 34 to detect whether the tray structure 1 is located within the clamping space 321, so as to avoid collision.

[0082] like Figure 3 As shown, the load-bearing structure 21 has a first magnetic chuck 2101, and the support structure 22 has a second magnetic chuck 221. The first magnetic chuck 2101 and the second magnetic chuck 221 are magnetically connected. In this way, the connection between the load-bearing structure 21 and the support structure 22 through the magnetic connection between the first magnetic chuck 2101 and the second magnetic chuck 221 makes the connection and separation between the load-bearing structure 21 and the support structure 22 simpler and more reliable, thus achieving structural simplicity.

[0083] In this embodiment, the first magnetic attractor 2101 is made of neodymium iron boron magnet, and the second magnetic attractor 221 is a reed switch.

[0084] Specifically, when the operator needs to load or unload workpieces, first turn off the reed switch to disconnect the magnetic connection between the first magnetic suction component 2101 and the second magnetic suction component 221. Then, pull the handle on the bearing structure 21 to pull the bearing structure 21 out of the support structure 22. Next, insert the positioning pin on the tray structure 1 into the positioning hole of the bearing structure 21. After the tray structure 1 and the bearing structure 21 are connected, the operator places the small workpiece in the receiving recess 101 on the tray structure 1, then pushes the handle to return the bearing structure 21 to its original position and turns on the reed switch to make the connection between the bearing structure 21 and the support structure 22 more stable. Afterward, the loading assembly 20 drives the drive wheel 281 to rotate the driven wheel 282 through the loading drive structure 23. The driven wheel 282 drives the lead screw 262 to rotate, causing the lead screw 262 to move the support structure 22 toward the clamping assembly 30. When the loading limit detection structure 210 detects that the loading limit structure 29 has reached its position, it turns off the loading drive structure 23. Subsequently, the clamping drive structure 35 of the clamping assembly 30 drives the clamping structure 32 to move, so that the clamping structure 32 clamps the tray structure 1, and the abutment drive structure 36 of the clamping assembly 30 drives the abutment structure 31 to abut against the end face of the tray structure 1. Then, the unloading drive structure 42 of the unloading assembly 40 drives the suction structure 41 to move towards the tray structure 1 and suction the workpiece. After the suction structure 41 has suctioned all the workpieces, the loading assembly 20 moves the tray structure 1 away from the clamping assembly 30, and the operator continues to place workpieces on the tray structure 1. Simultaneously, the clamping assembly 30 moves to the position of another loading assembly 20 under the drive of the clamping sliding structure 33. After the other loading assembly 20 transports the tray structure 1 to the clamping space 321, the clamping assembly 30 clamps the tray structure 1 and moves it into the operating range of the unloading assembly 40, thus completing the continuous unloading of workpieces.

[0085] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0086] The automatic loading and unloading device includes a loading assembly comprising a support structure, which is adjustablely positioned on a frame and supports a pallet structure, which in turn supports workpieces. A clamping assembly is mounted on the frame and includes an abutment structure and at least two opposing clamping structures forming a clamping space. The size of the clamping space is adjustable for clamping the pallet structure. The abutment structure is adjustablely positioned on the clamping structures to either avoid the pallet structure or abut against the end of the pallet structure within the clamping space furthest from the support structure. The unloading assembly includes an adsorption structure, which is adjustablely positioned on the frame and is used to adsorb workpieces located within the clamping space. In this way, when workers need to load or unload workpieces, they only need to place the workpiece on the pallet structure. The supporting structure then moves the pallet structure to allow the two clamping structures of the clamping assembly to hold it. Once the two clamping structures have secured the pallet, the suction structure of the unloading assembly picks up the workpiece from the pallet and places it on the production line. This reduces manual operation steps, lowers the difficulty and labor intensity for workers, and improves work efficiency, thus solving the problem of low workpiece loading and unloading efficiency in existing technologies. Simultaneously, the abutment structure's design ensures that it abuts against the pallet structure when the suction structure is holding the workpiece, preventing the pallet structure from shifting due to excessive suction force. This guarantees the reliability of the suction structure and the unloading assembly's unloading reliability. Furthermore, the adjustable position of the supporting structure expands its range of motion, making it easier for workers to place the pallet on it and for the clamping assembly to hold it. This improves the coordination between the loading and clamping assemblies, increasing the efficiency of the automatic loading and unloading device. Meanwhile, the adjustable position of the adsorption structure allows it to cooperate with the clamping components, expanding the range of workpieces that the adsorption structure can adsorb, thus improving the versatility of the adsorption structure and the automatic loading and unloading device. Furthermore, the adjustable clamping space allows the clamping components to adapt to pallet structures of different sizes, further enhancing the clamping versatility of the clamping components and the automatic loading and unloading device.
