[0074] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0075] The present application provides a loading and unloading device 10. Please refer to Figures 1 to 3 , Figure 1 which is a schematic diagram of the overall structure of the loading and unloading device (one angle) provided in the exemplary embodiment of the present disclosure, Figure 2 which is a schematic diagram of the overall structure of the loading and unloading device (another angle) provided in the exemplary embodiment of the present disclosure, Figure 3 which is a structural view of the adjustment component provided in the exemplary embodiment of the present disclosure.

[0076] The loading and unloading device 10 includes a machine base 1 and an adjustment component.

[0077] The machine base 1 has a loading station 11 and an unloading station 12 that are arranged at intervals.

[0078] It should be noted that the loading station 11 and the unloading station 12 can be arranged at intervals along the horizontal direction or along the gravity direction. Specifically, the present application does not limit this.

[0079] The machine base 1 includes two bearing parts 13. The two bearing parts 13 are respectively installed at the loading station 11 and the unloading station 12. Both of the two bearing parts 13 are used for placing a plurality of stacked trays 20, and each tray 20 is used for placing materials 30.

[0080] There are various ways to install the two carrying parts 13 at the loading station 11 and the unloading station 12. For example, in one embodiment, each carrying part 13 can be welded and fixed to the corresponding station of the machine base 1. In other embodiments, the carrying part 13 can also be snap-fitted and fixed to the corresponding station of the machine base 1 through a snap structure. In yet another embodiment, the carrying part 13 can also be fixed to the corresponding station of the machine base 1 through a screw member. The way each carrying part 13 is installed at the corresponding station of the machine base 1 can be selected according to needs, and the present application does not limit this.

[0081] At least one of the loading station 11 and the unloading station 12 is provided with an adjustment assembly. Thus, in one embodiment, the adjustment assembly can be provided only at the loading station 11. In yet another embodiment, the adjustment assembly can also be provided only at the unloading station 12. In other embodiments, the adjustment assembly can also be provided at both the loading station 11 and the unloading station 12 simultaneously. Specifically, the number of adjustment assemblies can be set according to requirements, and the present application does not limit this.

[0082] The adjustment assembly includes a plurality of adjustment parts 21 arranged at intervals along the circumferential direction of the carrying part 13.

[0083] It should be noted that the plurality of adjustment parts 21 can be arranged at equal intervals or at unequal intervals. Specifically, it is set according to needs, and the present application does not limit this.

[0084] The plurality of adjustment parts 21 are movably installed on the machine base 1 in a direction of approaching or separating from each other, so that the plurality of adjustment parts 21 can move between a first position and a second position. In the first position, the plurality of adjustment parts 21 are used to abut against the circumferential sides of the stacked plurality of trays 20, so as to enable the plurality of adjustment parts 21 to jointly exert a thrust on the stacked plurality of trays 20, thereby realizing the correction of the positions of the stacked plurality of trays 20, ensuring that the trays 20 are stacked in the correct position, and avoiding processing errors or equipment failures caused by position deviations in subsequent processing. In the second position, the plurality of adjustment parts 21 are used to separate from the circumferential sides of the stacked plurality of trays 20, which is usually the state when the trays 20 need to be taken out or put in, so as to avoid hindering the smooth movement of the trays 20.

[0085] In the loading and unloading device 10 according to the embodiments of the present application, by adjusting a plurality of adjusting parts 21 in the adjusting assembly, precise position correction can be performed on a plurality of stacked trays 20. In the first position, the adjusting part 21 abuts against the circumferential side of the tray 20 to ensure the accurate position of the tray 20 on the bearing part 13, thereby improving the positioning accuracy of subsequent loading and unloading operations and simultaneously improving the accuracy of picking up materials by the picking mechanism. Since the adjusting parts 21 can be arranged at intervals along the circumferential direction of the bearing part 13 and can be movably mounted on the machine base 1, the adjusting assembly can adapt to trays 20 of different sizes and shapes. By adjusting the positions of the plurality of adjusting parts 21, the trays 20 of different specifications can be corrected flexibly, increasing the versatility and flexibility of the loading and unloading device 10. The correction of the position of the tray 20 directly affects the placement accuracy of the material 30. By accurately adjusting the tray 20 through the adjusting assembly, the pauses and adjustment time in the production process can be reduced. Since the loading and unloading device 10 can automatically correct the position of the tray 20, the need for manual intervention is avoided, thereby improving the production efficiency. Through precise position correction, when the loading and unloading device 10 is working, collisions between other components and the plurality of stacked trays 20 can be avoided, reducing the risk of damage to the trays 20 and the materials 30. This not only helps to reduce the production cost but also ensures the smooth progress of the production process.

[0086] It should be noted that the articles to be tested of the material 30 are placed on the bearing part 13 at the loading station 11, and the tested good products of the material 30 are placed on the bearing part 13 at the unloading station 12.

[0087] Refer to Figures 3 to 4 , Figure 4 is Figure 3Partial structural schematic diagram of the adjustment component shown. In some embodiments, each bearing portion 13 is provided with a plurality of through holes 131 penetrating along the direction of gravity. The through holes 131 extend from the edge to the middle of the bearing portion 13. The plurality of through holes 131 are arranged in one-to-one correspondence with the plurality of adjustment portions 21. Each adjustment portion 21 is slidably mounted in the corresponding through hole 131 along the direction from the edge to the middle of the bearing portion 13. In this way, it is ensured that each adjustment portion 21 can slide independently in its respective through hole 131 without interference. This design makes the position adjustment more precise and controllable. Each adjustment portion 21 can be independently moved to an appropriate position according to needs to adapt to trays 20 of different shapes and sizes. The sliding mounting method makes the adjustment process simpler and faster. Compared with other complex mechanical adjustment methods, this design reduces the operation difficulty and adjustment time. The design of the through holes 131 enables the adjustment portions 21 to remain stable during the sliding process, reducing friction and wear caused by movement. In addition, the setting of the through holes 131 also realizes the limitation of the movement stroke of the adjustment portions 21 along the direction from the edge to the center of the bearing portion 13. In this way, it is possible to prevent the adjustment portions 21 from accidentally sliding out or moving excessively, thus ensuring the safety of the adjustment process.

[0088] Continue to refer to Figure 3 and Figure 4, in some embodiments, the adjustment assembly further includes a sliding part 22 and a connecting rod assembly. The sliding part 22 is slidably mounted on the machine base 1 along the direction of gravity. The connecting rod assembly includes a plurality of connecting rods 231. One end of each connecting rod 231 is hinged to the sliding part 22, and the other end of each connecting rod 231 is hinged to the adjustment part 21. Thus, when the sliding part 22 slides along the direction of gravity, it forms a mechanical linkage mechanism with the adjustment part 21 through the connecting rod assembly. This design makes the movement of the adjustment part 21 efficient and synchronous because a single action of the sliding part 22 can simultaneously drive multiple adjustment parts 21 to slide in the through holes 131. The hinged manner of the connecting rod assembly allows precise control of the position of the adjustment part 21. By adjusting the position of the sliding part 22, the angle of the connecting rod 231 can be precisely changed, thereby controlling the specific position of the adjustment part 21 in the through hole 131. This design makes it possible to achieve fine adjustment of the position of the tray 20. The operator only needs to control the up and down sliding of the sliding part 22 to achieve synchronous adjustment of multiple adjustment parts 21. This design simplifies the operation process, reduces the operation difficulty, and improves the work efficiency. The connecting rod assembly is connected to the sliding part 22 and the adjustment part 21 by a hinged manner, forming a stable triangular structure, which enhances the structural stability and durability of the entire adjustment assembly. This design helps to reduce possible mechanical failures during long-term use. Due to the flexibility of the connecting rod assembly and the sliding part 22, this design can adapt to trays 20 of different sizes and shapes. By adjusting the position of the sliding part 22 and the angle of the connecting rod 231, trays 20 of various specifications can be easily adapted, improving the versatility and adaptability of the loading and unloading device 10.

[0089] Refer again to Figure 3 and Figure 4In some embodiments, both the loading station 11 and the unloading station 12 are provided with adjustment components, and the loading and unloading device 10 further includes a driving component, which includes a first driving part 31 and a transmission mechanism. The first driving part 31 is installed on the base 1, and the first driving part 31 has an output shaft. The transmission mechanism drives and connects the output shaft and the sliding parts 22 of the two adjustment components, so as to convert the movement of the output shaft into the sliding of the two sliding parts 22. In this way, since both the loading station 11 and the unloading station 12 are provided with adjustment components, and the two adjustment components are synchronously controlled by the driving component, it can be ensured that the position correction of the multiple material trays 20 stacked in the loading station 11 and the unloading station 12 has a high degree of synchronization and coordination, thereby improving the efficiency of position correction. The first driving part 31 is connected to the sliding parts 22 of the two adjustment components through the transmission mechanism, so as to realize automatic position adjustment. This design not only reduces the burden on the operator, but also improves the accuracy of position adjustment. The adjustment components at the loading station 11 and the unloading station 12 can be controlled simultaneously by a single driving source (the first driving unit 31). This design simplifies the structure of the loading and unloading device 10 and improves energy efficiency. At the same time, the maintenance cost and failure rate of the loading and unloading device 10 are also reduced due to the reduction of unnecessary mechanical parts.

[0090] Reference Figure 3 and Figure 4In one embodiment, the first driving part 31 includes a driving motor having an output shaft. The driving motor is used as a power source and is responsible for providing rotational power. The transmission mechanism includes two rack parts, two rotating disks 322, a transmission shaft 323 and a transmission gear set 324. The two rack parts are respectively installed on the two sliding parts 22. Each rack part includes a plurality of first teeth 3211 arranged along the gravity direction. The two rotating disks 322 are arranged corresponding to the two rack parts. At least part of the circumference of the rotating disk 322 is provided with a plurality of second teeth 3221. The plurality of second teeth 3221 are arranged in sequence along the circumference of the rotating disk 322. Parts of the plurality of second teeth 3221 can be selectively meshed with parts of the plurality of first teeth 3211. The transmission shaft 323 is extended along the spacing direction of the loading station 11 and the unloading station 12. The two ends of the transmission shaft 323 are respectively connected to the two rotating disks 322. The axis is colinear with the axis of the transmission shaft 323, and the transmission gear set 324 is connected between the output shaft and the transmission shaft 323 to convert the rotation of the output shaft into the rotation of the transmission shaft 323. In this way, when the driving motor is working, the output shaft rotates, and the rotation of the output shaft is converted into the rotation of the transmission shaft 323 by the transmission gear set 324. When the transmission shaft 323 rotates, it will drive the two rotating disks 322 to rotate. The rotation of the rotating disk 322 will make the multiple second tooth portions 3221 arranged on the peripheral side of the rotating disk 322 selectively mesh with the multiple first tooth portions 3211 of the corresponding rack portion, so as to drive the two rack portions to move along the direction of gravity. Since the two rack portions are installed on the two sliding portions 22, the sliding portion 22 is driven to slide along the direction of gravity.

[0091] In addition, through the precise transmission of the transmission gear set 324, the rotational power of the driving motor is efficiently transmitted to the transmission shaft 323, thereby driving the rotating disk 322 to rotate. This design reduces the loss in the power transmission process and improves the overall transmission efficiency. The design of the first tooth portion 3211 on the rack portion and the second tooth portion 3221 on the rotating disk 322 allows the movement distance and speed of the sliding portion 22 to be accurately controlled, so that the sliding distance of the adjustment portion 21 can be accurately controlled, and the accuracy of the position correction of the stacked material trays 20 is improved. Since the transmission shaft 323 connects the two rotating disks 322, the adjustment components of the loading station 11 and the unloading station 12 can be moved synchronously, ensuring the coordination of the two stations. The gear transmission has high stability and can withstand large loads, ensuring the stability and durability of the entire transmission system.

[0092] It should be noted that, refer to Figure 4, the transmission gear set 324 includes a driving gear 3241 and a driven gear 3242 that mesh with each other. The axis of the driving gear 3241 is perpendicular to the axis of the driven gear 3242. The driving gear 3241 is sleeved on the output shaft and rotates synchronously with the output shaft, and the driven gear 3242 is sleeved on the transmission shaft 323 and rotates synchronously with the transmission shaft 323. In this way, the driving gear 3241 rotates synchronously with the output shaft, and the driven gear 3242 rotates synchronously with the transmission shaft 323, ensuring the directness and efficiency of power transmission. This design reduces the loss of power during transmission, making the entire transmission system more efficient. Through the meshing transmission of gears, a stable transmission ratio can be ensured. This means that between the output shaft and the transmission shaft 323, the conversion of rotational speed and torque is constant, which helps to achieve precise control and stable movement of the position of the sliding part 22. The axes of the driving gear 3241 and the driven gear 3242 are perpendicular to each other, and this configuration is beneficial to reducing the space occupied by the entire transmission system, making the structure of the drive assembly more compact. High-efficiency power transmission is achieved within a limited space, optimizing the space utilization rate.

[0093] In addition, at least a part of the circumferential side of the rotating disk 322 is provided with a plurality of second tooth parts 3221. In two embodiments, in one embodiment, the entire circumferential side of the rotating disk 322 is used to provide a plurality of second tooth parts 3221, so that the plurality of second tooth parts 3221 enclose to form a tooth ring. In this way, when it is necessary to make the sliding part 22 move closer to the bearing part 13, the rotating disk 322 is rotated clockwise, so that the plurality of second tooth parts 3221 on the rotating disk 322 can selectively mesh with the plurality of first tooth parts 3211 of the corresponding rack part, so that the sliding part 22 connected to the corresponding first rack part slides closer to the bearing part 13. When it is necessary to make the sliding part 22 move away from the bearing part 13, the rotating disk 322 is rotated counterclockwise, so that the plurality of second tooth parts 3221 on the rotating disk 322 can selectively mesh with the plurality of first tooth parts 3211 of the corresponding rack part, so that the sliding part 22 connected to the corresponding first rack part slides away from the bearing part 13.

[0094] Refer to Figure 3 and Figure 4, in another embodiment, the sliding part 22 includes two first connecting rods 2211 radially disposed on both sides of the corresponding rotating disk 322 along the radial direction of the rotating disk 322 and a second connecting rod 2212 connecting the two first connecting rods 2211. Both of the two first connecting rods 2211 extend along the direction of gravity. One end of the second connecting rod 2212 is hinged to a plurality of connecting rods 231. A plurality of first tooth portions 3211 are provided on the opposite side surfaces of the two first connecting rods 2211. A plurality of second tooth portions 3221 are provided at intervals on a part of the circumferential side of the rotating disk 322. The plurality of second tooth portions 3221 can be selectively engaged with the plurality of first tooth portions 3211 provided on one of the two first connecting rods 2211. When it is necessary to move the sliding part 22 closer to the bearing part 13, the rotating disk 322 is rotated clockwise, so that the plurality of second tooth portions 3221 on the rotating disk 322 can be selectively engaged with the plurality of first tooth portions 3211 provided on one of the two first connecting rods 2211, so that the sliding part 22 connected to the corresponding first rack part slides closer to the bearing part 13. When the rotating disk continues to rotate clockwise, the plurality of second tooth portions 3221 will move to be selectively engaged with the plurality of first tooth portions 3211 provided on the other of the two first connecting rods 2211, so that the sliding part 22 connected to the corresponding first rack part slides away from the bearing part 13, realizing that the rotating disk 322 can drive the sliding part 22 to move closer to or away from the bearing part 13 without reversing rotation. In this way, the operator does not need to frequently change the rotation direction of the driving motor when controlling the movement of the sliding part 22, which greatly simplifies the operation steps and improves the work efficiency. Frequent reversing rotation will increase the wear of mechanical components, especially key components such as gears and bearings. And this design reduces the need for reversing rotation, thereby reducing mechanical wear and extending the service life of the driving component. No need for reversing means that the operation process is smoother, reducing the pauses and delays that may be caused by reversing. This helps to improve the overall efficiency.

[0095] Referring to Figure 3 and Figure 4 , in some embodiments, a guiding structure is further provided between the sliding part 22 and the machine base 1. The guiding structure includes a guiding part 41 extending along the direction of gravity and a first matching part 42 adapted to the guiding part 41. Among the guiding part 41 and the first matching part 42, one of them is provided on the sliding part 22 and the other is provided on the machine base 1. In this way, the cooperation between the guiding part 41 and the first matching part 42 can ensure that the sliding part 22 moves linearly along the direction of gravity, preventing it from shifting or shaking during the movement, so as to realize the precise positioning and correction of the adjusting part 21 to the material tray 20. The guiding structure provides a stable movement path for the sliding part 22. It can maintain the stability of the adjusting assembly and prevent jitter or misalignment caused by external factors.

[0096] It should be noted that there are various types of the guiding portion 41 and the first mating portion 42. For example, in one embodiment, the guiding portion 41 is provided on the machine base 1 and includes a guiding rod extending along the direction of gravity. The first mating portion 42 is provided on the sliding portion 22 and includes a sliding block. The sliding block is provided with a through hole extending along the direction of gravity, and the sliding block is slidably mounted on the guiding rod through the through hole. In another embodiment, the guiding portion 41 is provided on the machine base 1 and includes a guiding protrusion extending along the direction of gravity. The first mating portion 42 is provided on the sliding portion 22 and includes a sliding table. The sliding table is provided with a sliding groove, and the sliding groove is slidably engaged with the sliding table along the direction of gravity.

[0097] Referring to Figure 3 and Figure 5 , Figure 5 is a cross-sectional schematic view of the adjusting portion provided in an exemplary embodiment of the present disclosure. In one embodiment, the adjusting portion 21 includes a base 211, an abutting plate 212 and an adjusting mechanism. A part of the base 211 is located in the through hole 131, and the base 211 is slidably connected to the bearing portion 13 along the direction from the edge to the middle of the bearing portion 13. The abutting plate 212 is provided on the side of the base 211 facing the material tray 20 and is movably mounted on the base 211 along the direction of approaching or departing from the base 211. The adjusting mechanism is mounted on the base 211 and is used to adjust the distance between the abutting plate 212 and the base 211. Thus, the presence of the adjusting mechanism enables the distance between the abutting plate 212 and the base 211 to be adjusted to adapt to material trays 20 of different sizes, thereby improving the adaptability and versatility of the loading and unloading device 10. The abutting plate 212 can be finely adjusted according to the actual position of the material tray 20 to ensure the precise alignment of the material tray 20 on the bearing portion 13, improving the precision of material 30 processing and reducing the processing errors caused by position deviation. The sliding connection between the base 211 and the bearing portion 13 ensures the stability of the adjusting portion 21 during movement, reducing shaking and vibration. Through the setting of the adjusting mechanism, the abutting plate 212 can be quickly adjusted to a suitable position before the material 30 is placed or taken out, accelerating the loading and unloading process and increasing the material 30 flow rate of the production line.

[0098] It should be noted that since the base 211 is slidably connected to the bearing portion 13 and the abutting plate 212 is movably connected to the base 211, the positions of both the base 211 and the abutting plate 212 can be adjusted. The adjustability of the position of the base 211 ensures that the position of the adjusting portion 21 on the entire bearing portion 13 can be accurately set, which helps to guide the material tray 20 to the correct starting position. The adjustable position of the abutting plate 212 allows for fine-tuning of the contact surface with the material tray 20 to ensure that the material tray 20 is evenly and accurately pushed into the designated position.

[0099] Referring to Figure 5, in some embodiments, the base 211 is provided with an installation hole 2111 penetrating along the moving direction of the abutting plate 212. The adjusting mechanism includes a sleeve 2131 and a rod 2132 sleeved inside the sleeve 2131. The sleeve 2131 is non-rotatably installed on the base 211, and the rod 2132 is rotatably installed on the base 211. One end of the sleeve 2131 is threadedly connected to one end of the rod 2132, and the other end of the sleeve 2131 passes through the installation hole 2111 and is connected to the abutting plate 212. In this way, through the threaded connection between the sleeve 2131 and the rod 2132, the abutting plate 212 is allowed to be accurately adjusted in position within a certain range, enabling the plurality of adjusting parts 21 to correct the positions of trays 20 of different sizes, improving the versatility and applicability of the loading and unloading device 10. Since the threaded connection has a self-locking property, once adjusted to the desired position, even under slight external vibrations or impacts, the position of the abutting plate 212 will not easily change, ensuring the stability of the position of the tray 20. The structures of the sleeve 2131 and the rod 2132 allow the abutting plate 212 to either advance towards the middle of the bearing part 13 or retreat towards the edge of the bearing part 13. This two-way adjustment ability enables the adjusting part 21 to adapt to the requirements of trays 20 of different sizes. Due to the rotational installation method of the sleeve 2131 and the rod 2132, their contact is rolling rather than sliding, which greatly reduces the wear between components and extends the service life of the adjusting mechanism.

[0100] Referring to Figure 5 , in some embodiments, the adjusting mechanism further includes a knob 2133. The knob 2133 is connected to the other end of the rod 2132, and the axis of the knob 2133 is collinear with the axis of the rod 2132. In this way, the operator can adjust the position of the abutting plate 212 by manually rotating the knob 2133 without the need for special tools, making the operation simple and easy. The knob 2133 usually has a relatively large diameter, which increases the lever arm for the operator to apply torque, making it more labor-saving to finely adjust the position of the abutting plate 212. Especially in cases where fine adjustment is required, the use of the knob 2133 can more easily achieve it. The collinear design of the axis of the knob 2133 and the rod 2132 reduces additional components and complex connections, simplifies the structure of the entire adjusting mechanism, and is beneficial to the overall integration and spatial layout.

[0101] It should be noted that the surface of the knob 2133 is provided with anti-slip textures. In this way, it can prevent slipping, simplify the operation of the operator to adjust the rotation of the rod 2132 through the knob 2133, and improve the user experience.

[0102] Referring to Figure 5, in some embodiments, the adjusting mechanism further includes a support portion 2134. The support portion 2134 is provided on the side of the base 211 facing away from the abutting plate 212. The support portion 2134 is formed with an installation cavity 2135. On both sides of the support portion 2134 disposed oppositely along the length direction of the sleeve rod 2132, a first through hole 2136 and a second through hole 2137 that are coaxial and both communicate with the installation cavity 2135 are respectively provided. The second through hole 2137 is disposed adjacent to the installation hole 2111. One end of the sleeve rod 2132 is located in the installation cavity 2135, and the other end sequentially passes through the second through hole 2137 and the installation hole 2111 and is connected to the abutting plate 212. One end of the sleeve rod 2132 passes through the first through hole 2136 and is threadedly connected to one end of the sleeve 2131. In this way, the setting of the support portion 2134 enhances the structural strength of the entire adjusting mechanism, ensures the stability of the sleeve rod 2132 and the sleeve 2131 when bearing force, and avoids deformation or failure caused by external load or vibration. The first through hole 2136 and the second through hole 2137 provide precise guidance for the sleeve rod 2132, ensure the linear movement of the sleeve rod 2132, prevent it from deflecting or shaking during adjustment, and improve the adjustment accuracy. Through the guiding action of the first through hole 2136 and the second through hole 2137, the relative movement between the sleeve rod 2132 and the sleeve 2131 is more stable, reduces the friction between the two, and extends the service life of the adjusting mechanism. The design of the installation cavity 2135 realizes the protection of the threaded connection between the sleeve rod 2132 and the sleeve 2131, prevents dust and impurities from entering the connection between the sleeve rod 2132 and the sleeve 2131, protects the thread from contamination, and ensures the smoothness of the adjustment process.

[0103] Referring to Figure 5 , in an embodiment, a rotation prevention structure is further provided between the support portion 2134 and the sleeve 2131. The rotation prevention structure includes a rotation prevention portion 51 extending along the length direction of the sleeve rod 2132 and a second cooperation portion 52 adapted to the rotation prevention portion 51. One of the rotation prevention portion 51 and the second cooperation portion 52 is provided on the support portion 2134, and the other is provided on the sleeve 2131. In this way, the cooperative installation of the rotation prevention portion 51 and the second cooperation portion 52 ensures that the sleeve 2131 will not rotate during axial movement, which is crucial for maintaining the position accuracy of the adjustment portion 21. Because once the sleeve 2131 rotates, the relative position with the sleeve rod 2132 will be changed, thereby affecting the final position of the abutting plate 212. The cooperative installation of the rotation prevention portion 51 and the second cooperation portion 52 limits the rotational freedom of the sleeve 2131, increases the stability of the entire adjusting mechanism, and avoids positioning errors caused by accidental rotation. Since the sleeve 2131 will not rotate, the operator only needs to adjust the position of the abutting plate 212 through the knob 2133 without worrying that the rotation of the sleeve 2131 will interfere with the adjustment result, making the operation more intuitive and simple.

[0104] It should be noted that there are various types of the rotation prevention part 51 and the second cooperation part 52. For example, in one embodiment, the rotation prevention part 51 is arranged on the support part 2134 and includes a rotation prevention groove arranged on the side wall of the installation cavity 2135. The rotation prevention groove extends along the length direction of the sleeve rod 2132. The second cooperation part 52 is arranged on the outer side wall of the sleeve 2131 and includes a slider. The slider is slidably installed in the rotation prevention groove along the length direction of the sleeve rod 2132. In other embodiments, the rotation prevention part 51 may further include a rotation prevention column extending along the length direction of the sleeve rod 2132, and the second cooperation part 52 may include a rotation prevention hole that is rotationally matched with the rotation prevention column. Specifically, the types of the rotation prevention part 51 and the second cooperation part 52 can be selected according to needs, and the present application does not limit this.

[0105] Referring to Figure 5 , in some embodiments, a storage groove 2112 is arranged on one side of the base 211 facing the abutting plate 212. The storage groove 2112 corresponds to the abutting plate 212 and is used for storing the abutting plate 212. In this way, the design of the storage groove 2112 allows the abutting plate 212 to be completely stored in the groove when not in use or when the distance between the base 211 and the abutting plate 212 is adjusted to the minimum, reducing the overall occupied space of the adjustment part 21, which is particularly important for a production environment with limited space. The storage groove 2112 can provide physical protection for the abutting plate 212, preventing it from being collided or scratched in a non-working state and extending the service life of the abutting plate 212.

[0106] Referring to the figure, in some embodiments, the machine base 1 further includes a housing 14. The housing 14 forms a receiving cavity 141. The loading station 11 and the unloading station 12 are located on the upper end surface of the housing 14. The housing 14 is respectively provided with openings 142 communicating with the receiving cavity 141 corresponding to the loading station 11 and the unloading station 12. Two carrying parts 13 are installed in the receiving cavity 141 and are respectively arranged corresponding to the two openings 142. A plurality of adjustment parts 21 of each adjustment assembly extend out of the corresponding opening 142. The sliding part 22 and the link assembly are both installed in the receiving cavity 141. In this way, installing the sliding part 22, the link assembly and the carrying part 13 in the receiving cavity 141 of the housing 14 can make the structure of the entire loading and unloading device 10 more compact and save space. The setting of the housing 14 and the receiving cavity 141 can provide protection for the sliding part 22, the link assembly and the carrying part 13, avoiding the sliding part 22, the link assembly and the carrying part 13 from being affected by the external environment and extending the service life of the loading and unloading device 10. The design of the opening 142 enables the adjustment part 21 to extend out and act on the tray 20, realizing position correction of a plurality of stacked trays 20 while maintaining a compact structure.

[0107] Referring to Figure 1, the bearing part 13 is connected to the housing 14 through a connecting component. The connecting component includes a plurality of vertical rods 101 located in the accommodation cavity 141. The plurality of vertical rods 101 surround the periphery of the opening 142. One end of the plurality of vertical rods 101 is connected to the top of the housing 14, and the other end of the plurality of vertical rods 101 is connected to the bearing part 13. In this way, the plurality of vertical rods 101 serve as a connecting bridge between the bearing part 13 and the housing 14, providing additional support and ensuring the structural stability of the bearing part 13. The layout of the plurality of vertical rods 101 can ensure that the load is evenly distributed on the housing 14, avoiding excessive local stress that may damage the structure, and improving the load-bearing safety and service life of the entire loading and unloading device 10. The vertical rods 101 are placed in the accommodation cavity, reducing the complexity of the external structure, optimizing the overall spatial layout of the loading and unloading device 10, and saving space in the production area.

[0108] Refer to Figure 1 , Figure 2 and Figure 6 , Figure 6 is a schematic structural diagram of the picking part provided in an exemplary embodiment of the present disclosure. In some embodiments, the loading and unloading device 10 further includes a picking mechanism 6. The picking mechanism 6 includes a picking part 61. The picking part 61 is movably installed on the machine base 1. The picking part 61 is used to pick and place the material 30 or the tray 20. In this way, the introduction of the picking part 61 enables the loading and unloading device 10 to automatically complete the picking and placing of the material 30 or the tray 20, reducing manual participation, improving the automation level of the production line, and reducing labor costs. The picking part 61 can quickly and accurately complete the grasping and releasing of the material 30 or the tray 20, reducing the waiting time during the loading and unloading process, accelerating the production rhythm, and improving production efficiency. The movably installed picking part 61 can adjust its position as needed to pick up the material 30 or the tray 20 at the loading station 11 or the unloading station 12, increasing the versatility and adaptability of the picking mechanism 6.

[0109] Refer to Figure 1 , in some embodiments, the loading and unloading device 10 further includes a traveling mechanism. The traveling mechanism is installed on the machine base 1. The traveling mechanism includes a plurality of traveling wheels 71. The plurality of traveling wheels 71 are arranged at intervals along the circumference of the machine base 1. Each traveling wheel 71 is used for rolling contact with the ground. In this way, the layout of the traveling wheels 71 enables the loading and unloading device 10 to move freely in the production area without additional conveyor belts or guide rails, enhancing the flexibility and adaptability of the loading and unloading device 10. The plurality of traveling wheels 71 are evenly distributed, which can ensure that the loading and unloading device 10 remains stable during movement, reducing bumps and vibrations. The distributed design of the traveling wheels 71 can evenly disperse the weight of the loading and unloading device 10, avoiding excessive pressure on a single traveling wheel 71, and extending the service life of the traveling wheels 71. By sharing the weight with a plurality of traveling wheels 71, the pressure on a single traveling wheel 71 on the ground is reduced, the wear of the workshop floor by a single traveling wheel 71 is reduced, and the maintenance cost is reduced.

[0110] It should be noted that the walking wheels 71 include omnidirectional wheels. In this way, the loading and unloading device 10 can achieve in-situ turning, improving the operation flexibility in a narrow space.

[0111] Referring to Figure 1 , in some embodiments, the loading and unloading device 10 further includes a support mechanism. The support mechanism includes a plurality of support legs 72. The plurality of support legs 72 are circumferentially spaced along the base 1. One end of each support leg 72 is connected to the base 1, and the other end of each support leg 72 is used to abut against the ground. Among them, the length of the support leg 72 is adjustable. In this way, the support leg 72 with adjustable length can be adjusted according to the unevenness of the ground, ensuring that the loading and unloading device 10 can maintain stability on any terrain and preventing it from tipping over. The adjustable length of the support leg 72 enables the loading and unloading device 10 to adapt to workbenches or material stacks 30 of different heights without an additional lifting platform, improving the flexibility and versatility of the loading and unloading device 10. By independently adjusting the length of each support leg 72, the levelness of the loading and unloading device 10 can be accurately corrected, ensuring that the device remains level during use, which is crucial for production processes that require high-precision operations. When the device needs to be maintained or cleaned, the support leg 72 can be adjusted to raise or lower the device, facilitating the operator to access the bottom of the device and simplifying the maintenance work.

[0112] It should be noted that the walking mechanism and the support mechanism can be set alternatively or both can be set at the same time. When both are set at the same time, when the position of the loading and unloading device 10 needs to be adjusted, the support leg 72 can be shortened so that the walking wheel 71 contacts the ground. At this time, the loading and unloading device 10 can freely roll on the ground through the walking wheel 71, and the operator can easily push or remotely control the device to the required position, improving the mobility and flexibility of the device. When the walking wheel 71 contacts the ground, the movement of the loading and unloading device 10 mainly relies on the rolling friction of the wheels. Compared with the static friction when the support leg 72 directly contacts the ground, the moving resistance is smaller and the operation is more labor-saving. After the position of the loading and unloading device 10 is adjusted, the support leg 72 is extended so that the support leg 72 firmly contacts the ground and the walking wheel 71 is lifted off the ground. In this way, during the operation, the walking wheel 71 is suspended in the air, avoiding the accidental movement of the loading and unloading device 10 under the action of accidental external forces and ensuring the positioning accuracy of the loading and unloading device 10 when performing the loading and unloading task.

[0113] Referring to Figure 1 and Figure 2, in one embodiment, the loading and unloading device 10 further includes a defective product placement rack 8. The defective product placement rack 8 is installed on the machine base 1 and is located between the loading station 11 and the unloading station 12. The defective product placement rack 8 is used for placing defective materials 30. In this way, the establishment of the defective product placement rack 8 enables defective materials 30 to be directly identified and removed on the production line without interrupting the production line for processing, avoiding production stagnation and improving the continuity and efficiency of the production line. The defective product placement rack 8 provides a clear storage location for defective materials 30, simplifies the logistics management process, facilitates the centralized processing of non-conforming products, and reduces the occurrence of material 30 chaos and errors. By setting the defective product placement rack 8 between the loading and unloading stations 12, defective products can be detected and isolated in a timely manner, which helps to improve the quality of the finished products, reduce rework and scrap in subsequent processes, and enhance the overall product quality. The combination of the automated loading and unloading device 10 and the defective product placement rack 8 reduces the need for manual inspection and classification of defective materials 30, reduces labor costs, and also reduces human errors. The defective product placement rack 8 is installed between the loading and unloading stations 12, making full use of the space on the production line and avoiding the need for additional storage areas.

[0114] Refer to Figure 2 and Figure 6 , in one embodiment, the loading and unloading device 10 further includes a first detection component 91. The first detection component 91 is installed on the picking part 61 and is used to detect the first side of the material 30 picked up by the picking part 61. In this way, through immediate detection, unqualified materials 30 can be screened out immediately, avoiding waste in subsequent processing steps and reducing production costs. The integration of the first detection component 91 and the picking part 61 enables the detection to be carried out synchronously with the picking of the material 30, reduces additional detection stations, optimizes the production layout, and improves the smoothness and efficiency of the production line. Automated detection replaces manual visual inspection, reduces the need for quality inspection personnel, reduces labor costs, and also reduces the error of human judgment.

[0115] It should be noted that there are various types of the first detection component 91. For example, the first detection component 91 may include a camera or a laser profiler. Specifically, the type of the first detection component 91 can be selected according to needs, and this application does not make any limitations in this regard.

[0116] Refer to Figure 2 , in one embodiment, the loading and unloading device 10 further includes a second detection component 92. The second detection component 92 is installed on the machine base 1 and is used to detect the second side of the material 30 picked up by the picking part 61. In this way, through immediate detection, unqualified materials 30 can be screened out immediately, avoiding waste in subsequent processing steps and reducing production costs. Automated detection replaces manual visual inspection, reduces the need for quality inspection personnel, reduces labor costs, and also reduces the error of human judgment.

[0117] It should be noted that there are various types of the second detection component 92. For example, the second detection component 92 may include a camera or a laser profiler. Specifically, the type of the second detection component 92 can be selected according to needs, and the present application does not limit this.

[0118] It should be noted that the first detection component 91 and the second detection component 92 can be set alternatively or simultaneously. When both are set simultaneously, the second detection component 92 can inspect the other side of the material 30, and together with the first detection component 91, it can achieve a full - range detection of the material 30 to ensure that the material 30 meets the quality standards in all dimensions. By detecting different sides of the material 30, the integrity and consistency of the material 30 can be evaluated more comprehensively, improving the accuracy and reliability of the detection. A single detection component may not cover all areas of the material 30. The addition of the second detection component 92 makes up for this defect to ensure that there is no detection blind spot. By cross - verifying multiple sides of the material 30, production errors caused by single - point detection failure can be reduced, improving the robustness of the production process. The data of the first detection component 91 and the second detection component 92 can be mutually verified, adding a layer of data redundancy and improving the reliability and robustness of the detection system.

[0119] Refer to Figure 6 , in an embodiment, the picking part 61 includes a mounting frame 611, a plurality of suction nozzles 612 and a second driving part 613. The mounting frame 611 is movably connected to the machine base 1. The plurality of suction nozzles 612 are arranged at intervals on the mounting frame 611. Each suction nozzle 612 is movably mounted on the mounting frame 611 along the gravity direction. The second driving part 613 is mounted on the mounting frame 611 to drive the plurality of suction nozzles 612 to move. In this way, the interval arrangement of the plurality of suction nozzles 612 enables the picking part 61 to stably pick up the material 30. The suction nozzles 612 are movably mounted along the gravity direction, which can ensure the stability of the material 30 during the picking process. Even when the surface of the material 30 is irregular or there are slight deviations, a good adsorption effect can be maintained. The second driving part 613 can quickly drive the plurality of suction nozzles 612 to move, accelerating the speed of picking up and releasing the material 30 and improving the production efficiency.

[0120] It should be noted that in other embodiments, the picking part 61 may also include a clamping jaw or a combination of a clamping jaw and the suction nozzle 612. Specifically, the present application does not limit this.

[0121] Refer to Figure 1 and Figure 2, in one embodiment, the picking mechanism 6 further includes a robotic arm 615. One end of the robotic arm is connected to the machine base 1, and the other end of the robotic base 211 is connected to the mounting bracket 611. In this way, the use of the robotic arm 615 enables the picking part 61 to achieve multi-axial movement and reach any position within the working area, improving the flexibility and accessibility of the picking operation. The robotic arm 615 can adapt to the picking requirements of materials 30 at different heights and angles, without the need to frequently adjust the equipment position, and is suitable for the picking tasks of various materials 30 and workstations. The robotic arm 615 usually has a high load capacity and can pick up and transport heavier materials 30, expanding the application range of the loading and unloading device 10 and improving production efficiency. The combination of the robotic arm 615 and the suction nozzle 612 can complete the picking and transportation of the tray 20. Compared with the prior art, there is no need to use conveyor devices such as belt conveyors, reducing the usage cost and occupied space.

[0122] Referring to Figure 6 , in one embodiment, the loading and unloading device 10 further includes a distance sensor 614. The distance sensor 614 is installed on the mounting bracket 611 and is used to detect the distance between the suction nozzle 612 and the material 30 to be picked up. The distance sensor 614 can monitor the distance between the suction nozzle 612 and the material 30 in real time, ensuring that the suction nozzle 612 picks up the material 30 at the correct position and height, and avoiding picking failure or damage to the material 30 caused by inaccurate position. By precisely controlling the distance between the suction nozzle 612 and the material 30, the extrusion or impact on the material 30 can be reduced, protecting the integrity and surface quality of the material 30.

[0123] In one embodiment, a movable baffle is detachably installed on the machine base 1. The movable baffle is located on the two opposite sides of the two bearing parts 13. The movable baffle is fixed by a bolt. In this way, the movable baffle can serve as a safety barrier to prevent operators or unauthorized personnel from approaching the operating equipment, reducing the risk of accidental contact or operation accidents. The movable baffle can prevent the material 30 from accidentally slipping or splashing during transportation, protecting the material 30 from damage, and keeping the production area clean. The detachable nature of the movable baffle makes equipment maintenance and cleaning easier, without the need to disassemble the entire equipment, reducing the maintenance cost and time. When not needed, the movable baffle can be easily removed, saving space and facilitating the movement and rearrangement of the loading and unloading device 10. The bolt fixing method makes the installation and disassembly of the movable baffle quick and simple, and the operator does not need to use special tools, improving work efficiency.

[0124] In some embodiments, a plurality of operation openings are provided on the peripheral side of the housing 14. An outward-opening door is installed in one of the plurality of operation openings, and sliding doors are installed in the others of the plurality of operation openings. In this way, the loading and unloading device 10 is made more open, and all the plurality of operation openings can be opened, facilitating the maintenance and debugging of the operators and improving the practicability of the loading and unloading device 10.

[0125] Reference Figure 1 and Figure 2 In some embodiments, the base 1 is also installed with a three-color light 94, which can be used to display the working status of the test equipment. For example, a red, yellow and green three-color light 94 is selected, wherein the red light indicates the shutdown state, the yellow light indicates the waiting state, and the green light indicates the working state. Of course, the representative color of each state can also be replaced. In addition, more colors or indicator lights with different words can be used as needed to indicate more states, and the present application does not limit this.

[0126] Reference Figure 1 and Figure 2 In one embodiment, the loading and unloading device 10 also includes a tray separator 93, which is installed at the loading station 11. When all the materials 30 to be tested in the top tray 20 among the stacked multiple trays 20 are picked up, the air pressure on the tray separator 93 will control the tray 20 below the top tray 20 and in contact with the top tray 20 to be stuck, and the suction nozzle 612 will absorb the top empty tray 20 and place it in the unloading area to realize the tray changing action.

[0127] It should be noted that the technology of the disk separator 93 is mature, and the specific structure of the disk separator 93 is not limited here.

[0128] The present disclosure exemplarily describes the working process of the minimum protection subject matter:

[0129] According to the model of the material tray 20, multiple knobs 2133 are twisted to make the sleeve rod 2132 rotate in the sleeve 2131, allowing the slider to move on the anti-rotation groove. At this time, the sleeve 2131 drives the abutment plate 212 to move from the accommodating groove to the direction opposite to the base 211, thereby changing the distance between the base plate and the abutment plate 212, and stacking the material tray 20 containing the material 30 on the bearing part 13 at the loading station 11. The movement of the robot arm 615 is controlled so that the robot arm 615 drives the picking part 61 to move to above the material tray 20 containing the material 30 at the loading station 11. The distance sensor 614 is used to check whether the picking part 61 is in place after grabbing the material 30 to be tested at the loading station 11 and putting it into the test fixture. If it is not placed properly or has an inclination, The oblique loading and unloading device 10 will alarm and start the second driving part 613, so that the suction nozzle 612 moves downward to the surface of the material 30 at the loading station 11 and adsorbs the material 30, so that the suction nozzle 612 can adsorb and grab the material 30. At the same time, the first detection component 91 can take a picture of the upper surface of the adsorbed and grabbed material 30 to see if it is a defective product. When the transported material 30 passes through the second detection component 92, the second detection component 92 detects whether the lower surface of the material 30 is a defective product. If the lower surface of the material 30 detected by the second detection component 92 is a defective product, the first detection component 91 and the second detection component 92 can be used to identify the label information of the material 30 and the visual positioning offset. Compensation will be achieved to ensure that the suction nozzle 612 grabs the material 30 and can be accurately placed in the test fixture At this time, the robot arm 615 places the material 30 and the material tray 20 on the defective product placement rack 8 for stacking through the picking part 61. If the material 30 is tested to be a good product, the robot arm 615 transports the material 30 to the carrying part 13 of the unloading station 12 for stacking through the picking part 61. During the transportation of the material 30, the drive motor is started to rotate the transmission gear set 324, and the transmission gear set 324 converts the rotation of the output shaft into the rotation of the transmission shaft 323. The transmission shaft 323 drives the rotating disk 322 to rotate, so that the multiple second tooth portions 3221 provided on the rotating disk 322 can selectively mesh with the multiple first tooth portions 3211 provided on one of the two first connecting rods 2211, and the sliding portion 22 is on the guide rod provided on the machine base 1 through the sliding block. The sliding part 22 moves back and forth. During the sliding process, the connecting rod 231 hinged at one end thereof will slide along the edge to the middle of the load-bearing part 13, thereby driving the adjusting part 21 hinged at the other end of the connecting rod 231 to slide along the edge to the middle of the load-bearing part 13. In this way, the multiple adjusting parts 21 at the loading station 11 or the unloading station 12 are brought closer to or away from each other, so that the material tray 20 loaded with the material 30 on the load-bearing part 13 can be placed in a standardized manner under the push of the abutment plate 212, which is convenient for the loading and unloading operations of the material 30. At the same time, the suction nozzle 612 grabs the material 30 in the material tray 20 on the load-bearing part 13 at the loading station 11 and takes it to the test fixture for testing. After the test is completed, the tested good products are placed in the material tray 20 in the unloading area.When the materials 30 in the tray 20 at the loading station 11 are picked up completely, the tray 20 under the empty tray 20 is clamped through the air pressure control on the tray divider 93. The suction nozzle 612 will adsorb the topmost empty tray 20 and place it in the unloading area to realize the tray changing operation. This process is repeated in a cycle to complete the testing of the materials 30.
