[0067] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0068] Reference below Figure 1-Figure 5 The loading and unloading device provided in the embodiment of the present application is described, and the loading and unloading device includes a frame 100, a first conveying mechanism 200, a second conveying mechanism 300, a transplanting mechanism 400 and a material dividing mechanism.

[0069] The frame 100 has a processing station. The material of the frame 100 includes but is not limited to stainless steel, aluminum alloy or titanium alloy.

[0070] The first conveying mechanism 200 is installed on the frame 100, and has a first loading and unloading station, a first material distribution station and a first transfer station arranged in sequence along the first horizontal direction. The connection method between the frame 100 and the first conveying mechanism 200 includes but is not limited to welding, threaded connection and snap connection. It should be noted that the distance between the first loading and unloading station, the first material distribution station and the first transfer station can be designed according to actual needs, and this embodiment does not make specific restrictions on this.

[0071] It is understandable that the first conveying mechanism 200 can transport the full tray 900 from the first loading and unloading station through the first material dividing station to the first transfer station, or transport the empty tray 900 from the first transfer station through the first material dividing station to the first loading and unloading station.

[0072] For ease of understanding, the first horizontal direction refers to the width direction of the material tray 900 , and the second horizontal direction refers to the length direction of the material tray 900 .

[0073] The second conveying mechanism 300 is installed on the frame 100 and is located above the first conveying mechanism 200, and has a second transfer station, a second material distribution station and a second loading and unloading station arranged in sequence along the first horizontal direction. The connection method between the frame 100 and the second conveying mechanism 300 includes but is not limited to welding, threaded connection and snap connection. It should be noted that the distance between the second loading and unloading station, the second material distribution station and the second transfer station can be designed according to actual needs, and this embodiment does not make specific restrictions on this.

[0074] It is understandable that the second conveying mechanism 300 can transport the empty tray 900 from the second transfer station to the second loading and unloading station after passing through the second material separation station, or transport the full tray 900 from the second loading and unloading station to the second transfer station after passing through the second material separation station. In addition, since the second conveying mechanism 300 is installed on the frame 100 and is located above the second conveying mechanism 300, the space occupied by the entire loading and unloading device can be saved, making the structure of the entire loading and unloading device more compact.

[0075] In this embodiment, the second conveying mechanism 300 is installed on the frame 100 and is located above the second conveying mechanism 300, that is, the processing station is located above the first transfer station, and is spaced apart from the second transfer station along the first horizontal direction. It should be noted that the distances between the processing station and the first transfer station and the second transfer station can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0076] The transplanting mechanism 400 is installed on the frame 100, and is used to realize the transfer of the material tray 900 between the first transfer station, the processing station and the second transfer station. The connection between the frame 100 and the transplanting mechanism 400 includes but is not limited to welding, threaded connection and snap connection.

[0077] It can be understood that the transplanting mechanism 400 can transport the full tray 900 from the first transfer station to the processing station so that the processing mechanism can transfer the products in the full tray 900 and then transport the empty tray 900 on the processing station to the second transfer station, or transport the full tray 900 from the second transfer station to the processing station so that the processing mechanism can transfer the products in the full tray 900 and then transport the empty tray 900 on the processing station to the first transfer station.

[0078] The material distribution mechanism is installed on the frame 100, and is used to collect and distribute the material tray 900 at least at the first loading and unloading station and the second loading and unloading station. The connection between the frame 100 and the material distribution mechanism includes but is not limited to welding, threaded connection and snap connection.

[0079] It can be understood that when multiple stacked material trays 900 move to the first material dividing station or the second material dividing station, the material dividing mechanism separates a separate material tray 900 therefrom so as to move the separate material tray 900 to the first transfer station or the second transfer station; when a separate material tray 900 moves to the first material dividing station or the second material dividing station, the material dividing mechanism places the separate material tray 900 under other stacked material trays 900 to realize the collection of material trays 900, so that a certain number of material trays 900 are collected and moved as a whole to the first loading and unloading station or the second loading and unloading station, and then can be taken away uniformly by humans or robotic arms.

[0080] It can be understood that the loading and unloading process of the entire loading and unloading device includes the following two types:

[0081] First, loading at the bottom and unloading at the top.

[0082] The first conveying mechanism 200 conveys a plurality of stacked full trays 900 from the first loading and unloading station to the first material dividing station, the material dividing mechanism conveys the plurality of full trays 900 to the first transfer station in sequence through the first conveying mechanism 200, the transplanting mechanism 400 moves the full trays 900 located at the first transfer station to the processing station so that the processing mechanism can transfer the products in the full trays 900, and then transports the empty trays 900 on the processing station to the second transfer station, the second conveying mechanism 300 conveys the empty trays 900 from the second transfer station to the second material dividing station, the material dividing mechanism places the empty trays 900 under other empty trays 900 that have been stacked together to collect the empty trays 900, so that the second conveying mechanism 300 conveys the plurality of empty trays 900 together to the second loading and unloading station;

[0083] Second, loading from the top and unloading from the bottom.

[0084] The second conveying mechanism 300 conveys multiple stacked full trays 900 from the second loading and unloading station to the second dividing station, and the dividing mechanism conveys the multiple full trays 900 to the second transfer station in turn through the second conveying mechanism 300, and the transplanting mechanism 400 moves the full trays 900 located at the second transfer station to the processing station so that the processing mechanism can transfer the products in the full trays 900, and then transports the empty trays 900 on the processing station to the first transfer station, and the first conveying mechanism 200 conveys the empty trays 900 from the first transfer station to the first dividing station, and the dividing mechanism places the empty trays 900 under other empty trays 900 that have been stacked together to realize the collection of the empty trays 900, so that the first conveying mechanism 200 conveys multiple empty trays 900 together to the first loading and unloading station.

[0085] The loading and unloading device provided in the embodiment of the present application saves floor space and realizes two-way loading and unloading, that is, loading can be done from the bottom and unloading from the top, or loading from the top and unloading from the bottom. Thus, the loading and unloading direction can be switched according to the layout of the production line and different loading and unloading requirements, thereby improving production efficiency and scope of use.

[0086] In some embodiments, Figure 1 As shown, the material dividing mechanism includes two material dividing structures 510 respectively located at the first material dividing station and the second material dividing station. Therefore, the two material dividing structures 510 can respectively perform material dividing and collecting operations on the material trays 900 located at the first material dividing station and the second material dividing station, thereby improving production efficiency.

[0087] In some embodiments, Figure 2 and Figure 3 As shown, the material distribution structure 510 includes a lifting assembly and two relatively arranged linear driving components 513, the fixed end of the lifting assembly is installed on the frame 100, and the driving end of the lifting assembly is connected to the first bearing platform 512, which is used to drive the first bearing platform 512 to move in the vertical direction, and the first bearing platform 512 is used to support the material tray 900; the fixed end of the linear driving component 513 is installed on the frame 100, and the driving end of the linear driving component 513 is connected to the material distribution limiter 514, which is used to drive the material distribution limiter 514 to move in the second horizontal direction, and the material distribution limiter 514 is used to support the material tray 900, and the second horizontal direction intersects with the first horizontal direction.

[0088] It can be understood that, in order to realize the collection and distribution of the material tray 900, the two material distribution stoppers 514 are arranged opposite to each other and are close to or away from each other along the second horizontal direction so as to support the two sides of the material tray 900 arranged along the second horizontal direction, and the first bearing platform 512 is located between the two second material distribution stoppers 514 so as to support the middle part of the material tray 900. Exemplarily, the lifting assembly includes but is not limited to a lifting cylinder; the linear drive member 513 includes but is not limited to a linear motor.

[0089] That is, when it is necessary to divide the multiple material trays 900, the first support platform 512 abuts against the bottom surface of the material tray 900 located at the bottom among the multiple stacked material trays 900, and the first support platform 512 is driven to move upward by the jacking assembly, and the two material dividing limiting components are made to approach each other in the second horizontal direction to abut against the bottom surface of the second material tray 900 from the bottom to the top, and the first support platform 512 is driven to move downward by the jacking assembly, so that the material tray 900 at the bottom and the first support platform 512 move synchronously and separate from the other material trays 900 until the material tray 900 can be placed on the conveyor belt (including at least one of the first conveyor belt 210 and the second conveyor belt 310);

[0090] When it is necessary to collect a single material tray 900, the first supporting platform 512 abuts against the bottom surface of the material tray 900 located at the bottom among the multiple stacked material trays 900, and the first supporting platform 512 is driven upward by the jacking assembly, and the two material dividing and limiting components are made close to each other in the second horizontal direction to abut against the bottom surface of the material tray 900 at the bottom, and the first supporting platform 512 is driven downward by the jacking assembly to support the single material tray 900, and the material tray 900 is driven upward to abut against the top surface of the material tray 900 and the bottom surface of the stacked material tray 900 located at the bottom, and then the two material dividing and limiting components 514 are moved away from each other in the second horizontal direction to separate from the material tray 900, so that the material tray 900 and the remaining material trays 900 are stacked together and placed on the first supporting platform 512.

[0091] In some embodiments, Figure 4 As shown, the material distribution stopper 514 includes a main body 5141, a support arm 5142 and an abutment block 5143. The main body 5141 is arranged at the driving end of the linear drive member 513; the support arm 5142 extends along the second horizontal direction; the two ends of the support arm 5142 along the second horizontal direction are respectively connected to the main body 5141 and the abutment block 5143, and the top surface of the support arm 5142 is higher than the top surface of the abutment block 5143. Exemplarily, the linear drive member 513 includes but is not limited to a linear motor.

[0092] It can be understood that by aligning the top surface of the support arm 5142 and the top surface of the abutment block 5143, a step is formed at the connection between the support arm 5142 and the abutment block 5143 to abut against the material tray 900, that is, the side of the support arm 5142 away from the main body 5141 abuts against the side of the material tray 900, and the top surface of the abutment block 5143 abuts against the bottom surface of the material tray 900, which provides support while limiting the material tray 900 along the second horizontal direction, helping to ensure that the material tray 900 remains stable during the material distribution and collection process, thereby improving the reliability and efficiency of the material distribution mechanism.

[0093] In some embodiments, Figure 4 As shown, two support arms 5142 and two abutment blocks 5143 are provided, and the two support arms 5142 are spaced apart along the first horizontal direction. The abutment blocks 5143 and the support arms 5142 are connected one by one, so that the material distribution limiter 514 is U-shaped to increase the contact area with the material tray 900 and improve the stability and uniformity of the support.

[0094] In some embodiments, Figure 4 As shown, a side of the abutment block 5143 away from the main body 5141 has two oppositely disposed first guide surfaces 51431 , and a distance between the two first guide surfaces 51431 along the up-down direction gradually decreases in a direction away from the main body 5141 .

[0095] It can be understood that, by providing two first guide surfaces 51431 arranged opposite to each other on each abutting block 5143, the distance between the two first guide surfaces 51431 in the up-down direction gradually decreases in the direction away from the main body 5141. That is, the first guide surface 51431 located at the top is inclined from top to bottom in the direction away from the corresponding main body 5141, and the first guide surface 51431 located at the bottom is inclined from bottom to top in the direction away from the corresponding main body 5141, thereby facilitating smooth insertion and withdrawal between multiple stacked trays 900, reducing impact and damage to the edge of the tray 900, and achieving accurate alignment with the tray 900.

[0096] In some embodiments, Figure 4 As shown, a surface of the support arm 5142 close to the abutment block 5143 includes a first inclined surface 51421 , and the first inclined surface 51421 is inclined from top to bottom in a direction away from the main body 5141 .

[0097] It is understandable that, considering that when the abutment block 5143 is inserted into and withdrawn from a plurality of stacked trays 900, a force is generated for the trays 900 to move in a second horizontal direction, the first inclined surface 51421 is provided to help guide the trays 900 to align and stack, thereby reducing friction and collision between the trays 900.

[0098] In some implementations, such as Figure 4 As shown, the bottom surface of the abutment block 5143 and the bottom surface of the support arm 5142 are spliced ​​together to form a continuous plane, which helps to disperse the weight of the material tray 900 and reduce single-point force, thereby improving the stability of the material tray 900 during the material distribution process and enhancing the supporting strength.

[0099] In some embodiments, Figure 4 As shown, the main body 5141, the support arm 5142 and the abutment block 5143 are an integrally formed structure, which improves the structural strength of the entire material dividing and limiting member 514 and simplifies the production process.

[0100] In some embodiments, Figure 2 and Figure 3As shown, the transplanting mechanism 400 includes a lifting structure 410, a second bearing platform 420, a moving structure 430 and a clamping assembly 440. The fixed end of the lifting structure 410 is arranged on the frame 100; the second bearing platform 420 is used to carry the material tray 900, and the driving end of the lifting structure 410 is connected to the second bearing platform 420, which is used to drive the second bearing platform 420 to move between the first transfer station and the processing station in the vertical direction; the fixed end of the moving structure 430 is arranged on the frame 100; the clamping assembly 440 is used to clamp the material tray 900, and the driving end of the moving structure 430 is connected to the clamping assembly 440, which is used to drive the clamping assembly 440 to move in the first horizontal direction. Exemplarily, the lifting structure 410 and the moving structure 430 both include but are not limited to linear motors.

[0101] It can be understood that when the second carrier 420 is in the first transfer station, the first conveying mechanism 200 conveys the material tray 900 from the first material distribution station to the second carrier 420, the lifting structure 410 drives the second carrier 420 to move upward to the processing station, the clamping assembly 440 clamps the material tray 900, and then the lifting structure 410 drives the second carrier 420 to move downward to the first transfer station, and the clamping assembly 440 drives the material tray 900 to move along the first horizontal direction to the second transfer station. Two transfer stations; when the clamping assembly 440 is in the second transfer station and clamps the material tray 900 delivered from the second material distribution station, the clamping assembly 440 drives the material tray 900 to move along the first horizontal direction to the processing station, and the lifting structure 410 drives the second load platform 420 to move upward to the processing station. After the material tray 900 is loaded on the second load platform 420, the clamping assembly 440 releases the material tray 900, and the clamping assembly 440 drives the second load platform 420 to move downward to the first transfer station.

[0102] In some embodiments, Figure 5 As shown, the clamping assembly 440 includes a mounting seat 441, a first support block 442 and two second support blocks 443. The mounting seat 441 is connected to the driving end of the movable structure 430 and forms an escape space for evading the second supporting platform 420; the first support block 442 is arranged on the top of the mounting seat 441, and is used to support the end of the material tray 900 along the first horizontal direction; the second support block 443 is movably arranged on the top of the mounting seat 441 along the second horizontal direction, and the two second support blocks 443 are used to respectively support the ends of the material tray 900 along the second horizontal direction.

[0103] It can be understood that the projection of the mounting seat 441 in the up-down direction is in a U-shape, so that the second carrier 420 can enter or exit the avoidance space under the drive of the lifting structure 410, reducing the possibility of interference between the clamping assembly 440 and the second carrier 420 during the transfer of the tray 900. At the same time, since the first support block 442 supports the end in the first horizontal direction and the second support blocks 443 support the ends of the tray 900 in the second horizontal direction, that is, the first support block 442 and the two second support blocks 443 surround the outside of the avoidance space and are in contact with the three sides and the bottom surface of the tray 900, thus ensuring the stability of the tray 900 during the movement in the first horizontal direction. In addition, the second support block 443 is movably arranged at the top of the mounting seat 441 in the second horizontal direction, which can not only adapt to trays 900 of different sizes, but also reduce the interference between the second carrier 420 driving the tray 900 into the avoidance space and the tray 900, improving the versatility and flexibility of the clamping assembly 440.

[0104] In this embodiment, as Figure 3 and Figure 5 shown, the opening of the U-shape faces the second conveying mechanism 300, that is, the first support block 442 is located on the side away from the second conveying mechanism 300 in the first horizontal direction; of course, in other embodiments, when the mounting seat 441 is higher than the second conveyor belt 310, the opening of the U-shape can also face away from the second conveying mechanism 300, that is, the first support block 442 is located on the side close to the second conveying mechanism 300 in the first horizontal direction, and this embodiment does not make specific limitations on this.

[0105] In some embodiments, as Figure 5 shown, the clamping assembly 440 further includes two side-pushing driving members 450. The two side-pushing driving members 450 correspond to the two second support blocks 443 one by one. The fixed end of the side-pushing driving member 450 is arranged on the mounting seat 441, and the driving end of the side-pushing driving member 450 is connected to the second support block 443 for driving the second support block 443 to move in the second horizontal direction. Exemplarily, the side-pushing driving member 450 includes but is not limited to a linear motor.

[0106] In some embodiments, as Figure 5 shown, the end face of the first support block 442 arranged in the first horizontal direction has a second guiding surface 4421, and the second guiding surface 4421 is inclined downward from top to bottom in the direction close to the avoidance space. It should be noted that the inclination angle and the inclination magnitude of the second guiding surface 4421 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

[0107] It can be understood that the second guide surface 4421 helps to guide the material tray 900 to transfer smoothly from the second supporting platform 420 to the first support block 442, reducing the possibility of hard contact of the material tray 900 during the transfer process, thereby protecting the edge of the material tray 900 from damage and extending the service life of the material tray 900.

[0108] In some embodiments, Figure 5 As shown, the end surface of the second support block 443 arranged along the second horizontal direction has a third guide surface 4431, and the third guide surface 4431 is inclined from top to bottom toward the direction close to the avoidance space. It should be noted that the inclination angle and inclination size of the third guide surface 4431 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0109] It can be understood that the third guide surface 4431 helps to guide the material tray 900 to transfer smoothly from the second supporting platform 420 to the second support block 443, reducing the possibility of hard contact of the material tray 900 during the transfer process, thereby protecting the edge of the material tray 900 from damage and extending the service life of the material tray 900.

[0110] In some embodiments, Figure 2 As shown, the first conveying mechanism 200 includes two first conveyor belts 210 and a first driving member 220 spaced apart along the second horizontal direction. The first material dividing station is arranged near the middle of the first conveyor belt 210. The first conveyor belt 210 extends along the first horizontal direction for carrying the material tray 900. The second horizontal direction intersects with the first horizontal direction. The fixed end of the first driving member 220 is installed on the frame 100. The driving end of the first driving member 220 is connected to at least one first conveyor belt 210 for driving the two first conveyor belts 210 to run synchronously. The first driving member 220 includes but is not limited to a motor reducer.

[0111] It can be understood that the first loading platform 512 and the second loading platform 420 located at the first material distribution station are both located between the two first conveyor belts 210. When the first conveyor belt 210 drives the material tray 900 to move along the first horizontal direction, the material tray 900 can be transferred between the first conveyor belt 210 and the first loading platform 512 through the jacking assembly, and the material tray 900 can be transferred between the first conveyor belt 210 and the second loading platform 420 through the lifting structure 410. In addition, by providing two first conveyor belts 210 spaced apart and running synchronously along the second horizontal direction, the stability of the material tray 900 during the conveying and transfer processes can be ensured.

[0112] In some embodiments, Figure 2As shown, the first transfer station is arranged at one end of the first conveyor belt 210; the first conveying mechanism 200 also includes a mounting frame 230 and a plurality of conveying rollers 240 arranged at intervals along a first horizontal direction, the mounting frame 230 is arranged outside the other end of the first conveyor belt 210 and is provided with a first loading and unloading station; the conveying rollers 240 are rotatably arranged on the mounting frame 230.

[0113] It can be understood that the conveyor roller 240 and the lifting structure 410 are respectively located on both sides of the first conveyor belt 210, that is, the first loading and unloading station is located at the conveyor roller 240, and the first transfer station is located on the side of the first conveyor belt 210 away from the conveyor roller 240. By arranging the conveyor roller 240 on the mounting frame 230, it is not only convenient to load and unload materials, but also helps the material tray 900 to switch smoothly between the static state and the moving state, reduces the impact of the material tray 900 during the state switching process, helps the material tray 900 to be correctly positioned on the first conveyor belt 210, and reduces the deviation of the material tray 900 during the conveying process and the possibility of the product overflowing from the edge of the material tray 900 due to the acceleration of the first conveyor belt 210. Exemplarily, the conveyor roller 240 extends along the second horizontal direction.

[0114] In some embodiments, Figure 3 As shown, the second conveying mechanism 300 includes two second conveyor belts 310 and a second driving member 320 spaced apart along a second horizontal direction, a second material dividing station is arranged near the middle of the second conveyor belt 310, a second transfer station and a second loading and unloading station are arranged at both ends of the second conveyor belt 310, and the second conveyor belt 310 extends along the first horizontal direction for carrying the material tray 900, and the second horizontal direction intersects with the first horizontal direction; the fixed end of the second driving member 320 is mounted on the frame 100, and the driving end of the second driving member 320 is connected to at least one second conveyor belt 310 for driving the two second conveyor belts 310 to run synchronously. The second driving member 320 includes but is not limited to a motor reducer.

[0115] It can be understood that the first loading platform 512 located at the second material distribution station is located between the two second conveyor belts 310. When the second conveyor belt 310 drives the material tray 900 to move along the first horizontal direction, the lifting assembly can realize the transfer of the material tray 900 between the second conveyor belt 310 and the second loading platform 420. In addition, by providing two second conveyor belts 310 spaced apart and running synchronously along the second horizontal direction, the stability of the material tray 900 during the conveying and transfer process can be ensured.

[0116] In some embodiments, Figure 3As shown, the second conveying mechanism 300 further includes a third bearing platform 330 and a lifting drive member. The third bearing platform 330 is located between the two second conveyor belts 310 and close to the second transfer station, and is used to carry the material tray 900. The fixed end of the lifting drive member is arranged on the frame 100, and the driving end of the lifting drive member is connected to the third bearing platform 330, and is used to drive the material tray 900 to move in the vertical direction. The lifting drive member includes but is not limited to a lifting cylinder.

[0117] It can be understood that when the clamping assembly 440 clamps the material tray 900 and moves above the end of the second conveyor belt 310 along the first horizontal direction, the lifting drive member drives the third load platform 330 to move upward so that the top surface of the third load platform 330 abuts the bottom surface of the material tray 900, and the clamping assembly 440 moves in the opposite direction along the first horizontal direction, and the lifting drive member drives the third load platform 330 to move downward until the material tray 900 is placed on the second conveyor belt 310, thereby achieving a smooth transfer of the material tray 900 from the clamping assembly 440 to the second conveyor belt 310.
