[0050] 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.

[0051] Reference below Figure 1-Figure 5 The bidirectional motion loading and unloading mechanism provided in the embodiment of the present application is described, and the bidirectional motion loading and unloading mechanism includes a frame 100, a conveying mechanism 200, a lifting and transplanting mechanism 300 and a material dividing mechanism 400.

[0052] The material of the frame 100 includes but is not limited to stainless steel, aluminum alloy or titanium alloy.

[0053] The conveying mechanism 200 is installed on the frame 100, and the conveying mechanism 200 has a first loading and unloading station and a transfer station arranged at intervals along a first horizontal direction, which is used to realize the transfer of the material tray 900 between the first loading and unloading station and the transfer station.

[0054] It is understandable that the conveying mechanism 200 can transport a full tray from the first loading and unloading station to the transfer station, or transport an empty tray from the transfer station to the first loading and unloading station. The connection method between the frame 100 and the 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 and the transfer station can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0055] The lifting and transplanting mechanism 300 is installed on the frame 100. The lifting and transplanting mechanism 300 has a processing station and a second loading and unloading station arranged at intervals along the first horizontal direction. The processing station is located directly above the transfer station and is used to realize the transfer of the material tray 900 between the transfer station, the processing station and the second loading and unloading station.

[0056] It is understandable that the lifting and transplanting mechanism 300 can transport the full tray from the transfer station to the processing station so that the processing mechanism can process and transfer the product, and then transport the empty tray on the processing station to the second loading and unloading station, or transport the full tray from the second loading and unloading station to the processing station so that the processing mechanism can process and transfer the product, and then transport the empty tray on the processing station to the transfer station. The connection method between the frame 100 and the lifting and transplanting mechanism 300 includes but is not limited to welding, threaded connection and snap connection. It should be noted that the distance between the processing station and the second loading and unloading station and the distance between the processing station and the transfer station can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0057] The material distribution mechanism 400 is installed on the frame 100 and is located above the conveying mechanism 200, and is used to collect and distribute the material trays 900 at the second loading and unloading station.

[0058] It can be understood that after the lifting and transplanting mechanism 300 transports the empty tray to the second loading and unloading station, the separation mechanism places the empty tray under other empty trays that have been stacked together to collect the empty trays. When a certain number of empty trays are collected, they can be taken away manually or by a robotic arm. When multiple full trays are stacked at the second loading and unloading station, the separation mechanism separates the materials to produce a separate full tray, thereby facilitating the lifting and transplanting mechanism 300 to move the separate full tray to the processing station.

[0059] It can be understood that the loading and unloading process of the entire lifting and transplanting mechanism 300 includes the following two processes:

[0060] First, loading from the bottom and loading from the top.

[0061] The conveying mechanism 200 moves a single full tray from the first loading and unloading station to the transfer station, the lifting and transplanting mechanism 300 moves the full tray at the transfer station to the processing station so that the processing mechanism can process and transfer the product, and then transports the empty tray at the processing station to the second loading and unloading station, and the separation mechanism places the empty tray under other empty trays that have been stacked together to collect the empty trays, so that multiple stacked empty trays can be taken away at the same time later;

[0062] Second, loading from the top and unloading from the bottom.

[0063] A plurality of full trays are stacked above the second loading and unloading station, and a separation mechanism separates a single full tray by dividing the materials. The lifting and transplanting mechanism 300 moves the single full tray to the processing station so that the processing mechanism can process and transfer the product, and then transport the empty tray on the processing station to the transfer station. When a plurality of empty trays are stacked at the transfer station, the conveying mechanism 200 moves the plurality of stacked empty trays from the transfer station to the first loading and unloading station so as to subsequently remove the plurality of stacked empty trays.

[0064] According to the bidirectional motion loading and unloading mechanism provided in the embodiment of the present application, the material dividing mechanism 400 is arranged at the second loading and unloading station to realize the collection and dividing of the material tray 900, and cooperates with the conveying mechanism 200 and the jacking and transplanting mechanism 300, thereby realizing bidirectional loading and unloading, that is, the material can be loaded from the bottom to the top, and the material can be loaded from the top and unloaded from the bottom, so that the loading and unloading direction can be switched according to the layout of the production line and the loading and unloading needs of the user, thereby improving production efficiency and scope of use.

[0065] In some embodiments, Figure 3As shown, the material dividing mechanism 400 includes a supporting platform 410, a lifting structure 420 and two relatively arranged material dividing limit parts 430, the supporting platform 410 is used to support the material tray 900; the fixed end of the lifting structure 420 is installed on the supporting platform 410, and is used to drive the supporting platform 410 to move in the vertical direction to approach or move away from the second loading and unloading station; the two material dividing limit parts 430 can approach or move away from each other along the second horizontal direction; the material dividing limit parts 430 are used to support the material tray 900.

[0066] It can be understood that in order to realize the collection and distribution of the material tray 900, the two second material distribution limit parts 430 are arranged relatively along the second horizontal direction, and the projection of the supporting platform 410 along the horizontal direction is located between the two second material distribution limit parts 430, and multiple stacked material trays 900 are arranged above the second loading and unloading station through the material distribution limit parts 430, that is, the bottom surface of the material tray 900 located at the bottom is abutted against the top surface of the material distribution limit part 430.

[0067] When it is necessary to distribute the materials among multiple full trays, the lifting structure 420 is used to drive the supporting platform 410 upward to approach the stacked full trays until it abuts against the bottom surface of the full tray at the bottom, and then the two material distribution limiting parts 430 are moved away from each other in the second horizontal direction to separate from the full trays, and then the lifting structure 420 is used to drive the supporting platform 410 to move downward and make the two material distribution limiting parts 430 approach each other in the second horizontal direction to abut against the bottom surface of the second full tray from the bottom, and then the lifting structure 420 is used to drive the supporting platform 410 away from the material distribution limiting parts 430, even if the full tray located on the supporting platform 410 and separated from the second material distribution limiting parts 430 is located at the second loading and unloading station;

[0068] When a single empty tray needs to be stacked with other empty trays from the second loading and unloading station, the lifting structure 420 drives the carrying platform 410 to move upward first until it carries the empty tray at the second loading and unloading station, and drives the empty tray to move upward to approach the two material dividing limit parts 430 and make the top surface of the empty tray abut against the bottom surface of the stacked empty trays located at the bottom surface, and then makes the two material dividing limit parts 430 move away from each other in the second horizontal direction to detach from the empty tray, and then drives the carrying platform 410 to move upward by the lifting structure 420 and makes the two material dividing limit parts 430 approach each other in the second horizontal direction to abut against the bottom surface of the empty tray.

[0069] It should be noted that the material of the carrying platform 410 includes but is not limited to stainless steel, aluminum alloy or titanium alloy, etc. The size and shape of the carrying platform 410 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this. The lifting structure 420 includes but is not limited to a screw lift.

[0070] In some embodiments, Figure 3As shown, the material distribution limit part 430 includes at least one limit block 431 and a first driving member 432. The top surface of the limit block 431 can abut against the bottom surface of the material tray 900. The fixed end of the first driving member 432 is installed on the frame 100, and the driving end of the first driving member 432 is used to drive the limit block 431 to move along the second horizontal direction to approach or move away from the second loading and unloading station.

[0071] It is understandable that the first driving member 432 enables the limit block 431 to move along the second horizontal direction to support or avoid the material tray 900, that is, the top surface of the limit block 431 abuts against the bottom surface of the material tray 900, and the outer side wall of the limit block 431 can also selectively abut against the outer side wall of the material tray 900 under the action of the first driving member 432, so as to further improve the support strength and stability of the material tray 900. It should be noted that the material of the limit block 431 includes but is not limited to stainless steel, aluminum alloy or titanium alloy. The size and shape of the limit block 431 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this. The first driving member 432 includes but is not limited to a linear cylinder.

[0072] In some embodiments, each material distribution limiting portion 430 is provided with a plurality of limiting blocks 431 , and the plurality of limiting blocks 431 are spaced apart along the first horizontal direction.

[0073] It is understandable that if Figure 3 As shown, multiple limit blocks 431 are provided to further improve the support strength and stability, and ensure that the material tray 900 is evenly stressed. It should be noted that multiple includes two and more than two. In this embodiment, the limit blocks 431 correspond to the first driving members 432 one by one. Of course, in other embodiments, multiple first driving members 432 can also be controlled by one limit block 431, and this embodiment does not specifically limit this.

[0074] In some embodiments, Figure 4 and Figure 5 As shown, the jacking and transplanting mechanism 300 includes a transfer platform 310, a jacking structure 320 and two relatively arranged clamping parts 330, the transfer platform 310 is used to carry the material tray 900; the fixed end of the jacking structure 320 is installed on the frame 100, and the driving end of the jacking structure 320 is used to drive the transfer platform 310 to move between the transfer station and the processing station in the vertical direction; the clamping part 330 is movably arranged on the frame 100 for clamping and driving the material tray 900 to move between the processing station and the second loading and unloading station.

[0075] It is understandable that in order to realize bidirectional loading and unloading, the two clamping parts 330 are arranged relatively along the second horizontal direction, and the projection of the transfer platform 310 along the horizontal direction is located between the two clamping parts 330 .

[0076] In order to realize the transfer of the material tray 900, when it is necessary to transfer the full material tray from the second loading and unloading station to the processing station, the full material tray located at the second loading and unloading station and supported on the supporting platform 410 is moved to the processing station through the clamping part 330. When the processing is completed, the lifting structure 320 drives the transfer platform 310 to move upward close to the processing station until the bottom surface of the empty material tray abuts against the top surface of the transfer platform 310, and then the clamping part 330 releases the empty material tray so that the lifting structure 320 drives the transfer platform 310 to move upward close to the processing station. 10 moves downward until the empty tray is located at the transfer station; when the full tray needs to be transferred from the transfer station to the processing station, the lifting structure 320 drives the transfer platform 310 to move downward close to the transfer station until the bottom surface of the full tray abuts against the top surface of the transfer platform 310, and then the lifting structure 320 drives the transfer platform 310 to move upward close to the processing station, and enables the clamping part 330 to clamp the full tray. When the processing is completed, the clamping part 330 drives the empty tray to move along the first direction close to the second loading and unloading station.

[0077] It should be noted that the material of the transfer platform 310 includes but is not limited to stainless steel, aluminum alloy or titanium alloy. The size and shape of the carrying platform 410 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this. The lifting structure 320 includes but is not limited to a screw lift and a linear cylinder.

[0078] In some embodiments, Figure 4 As shown, the clamping portion 330 includes an abutment plate 331 and a supporting plate 332. The abutment plate 331 is movably arranged on the frame 100 and extends along the first direction. One side wall of the abutment plate 331 can abut against the outer wall of the material tray 900; the supporting plate 332 is connected to the other side wall of the abutment plate 331, and at least part of the top surface of the supporting plate 332 can abut against the bottom surface of the material tray 900. The materials of the abutment plate 331 and the supporting plate include but are not limited to stainless steel, aluminum alloy or titanium alloy. The connection method between the abutment plate 331 and the supporting plate includes but is not limited to threaded connection, snap connection and welding. It should be noted that the size and shape of the abutment plate 331 and the supporting plate can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0079] It can be understood that by abutting the outer wall of the material tray 900 along the second horizontal direction and close to the side wall of the abutment plate 331, and abutting the top surface and bottom surface of the support plate 332, not only can the material tray 900 be fixed better when it is moved along the first direction, but also it can be ensured that the material tray 900 does not shake when it is separated from the transfer platform 310.

[0080] In some embodiments, Figures 1 to 4As shown, in order to enable the clamping portion 330 to clamp and drive the material tray 900 to move between the processing station and the second loading and unloading station, the lifting and transplanting mechanism 300 also includes a second driving member 340 and a third driving member 350, and the fixed end of the second driving member 340 is installed on the frame 100; the fixed end of the third driving member 350 is installed on the driving end of the second driving member 340, and is used to reciprocate along the first horizontal direction under the action of the second driving member 340, and the clamping portion 330 is installed on the driving end of the third driving member 350, and is used to reciprocate along the second horizontal direction under the action of the third driving member 350.

[0081] It can be understood that the abutment plate 331 is installed at the driving end of the third driving member 350, that is, when the material tray 900 is placed on the transfer platform 310 and is located at the processing station, the abutment plate 331 drives the supporting plate 332 to approach the material tray 900 along the second horizontal direction until abutment under the drive of the third driving member 350, and then the abutment plate 331 and the supporting plate 332 move the material tray 900 to the second loading and unloading station along the first horizontal direction under the action of the second driving member 340; when the material tray 900 is in the second loading and unloading station, the abutment plate 331 and the supporting plate 332 move to the second loading and unloading station along the first horizontal direction under the action of the second driving member 340, and then the abutment plate 331 drives the supporting plate 332 to approach the material tray 900 along the second horizontal direction until abutment under the drive of the third driving member 350, and then the abutment plate 331 and the supporting plate 332 move to the transfer station along the first horizontal direction under the action of the second driving member 340. The second driving member 340 and the third driving member 350 include, but are not limited to, linear cylinders.

[0082] In some embodiments, Figures 1 to 3 as well as Figure 5 As shown, the conveying mechanism 200 includes two conveyor belts 210 spaced apart along the second direction and a fourth driving member 220, and the projection of the transfer platform 310 on the horizontal plane is located between the two conveyor belts 210, and the conveyor belt 210 extends along the first horizontal direction for carrying the material tray 900; the fixed end of the fourth driving member 220 is mounted on the frame 100, and the driving end of the fourth driving member 220 is connected to at least one conveyor belt 210 for driving the two conveyor belts 210 to run synchronously.

[0083] It is understandable that when the transfer platform 310 moves downward to the transfer station under the action of the jacking structure 320, the top surface of the transfer platform 310 is at the same level as the top surface of the conveyor belt 210 and is located between the two conveyor belts 210, thereby facilitating the transfer of the material tray 900 between the conveyor belt 210 and the transfer platform 310. The fourth driving member 220 includes but is not limited to a motor reducer.

[0084] In some embodiments, Figures 1 to 3As shown, the bidirectional motion loading and unloading mechanism also includes two groups of opposing photoelectric switches 500, which are arranged on the frame 100 and are respectively arranged on the outside of the transfer station and the second loading and unloading station, for checking whether the material tray 900 is full of material.

[0085] It should be noted that the through-beam photoelectric switch 500 is composed of a transmitter and a receiver. Its working principle is that the light emitted by the transmitter directly enters the receiver. When the material tray 900 passes between the transmitter and the receiver to block the light, the through-beam photoelectric switch 500 generates a switch signal. It has the advantages of being able to identify opaque reflective objects, being susceptible to interference, having high sensitivity, high resolution, high brightness, low power consumption, fast response time and long service life.

[0086] It can be understood that when materials are loaded from above and fed from below, the opposing photoelectric switch 500 arranged at the transfer station is used to timely determine whether the number of empty trays stacked on the transfer platform 310 has reached a preset number; when materials are loaded from below and fed from above, the opposing photoelectric switch 500 arranged at the second loading and unloading station is used to timely determine whether the number of empty trays stacked on the limit block 431 has reached a preset number.

[0087] In some embodiments, Figure 4 and Figure 5 As shown, the bidirectional motion loading and unloading mechanism also includes a plurality of safety gratings 600, which are arranged on the frame 100 and are respectively arranged outside the first loading and unloading station, the transfer station, the processing station and the second loading and unloading station, so as to improve the safety, automation and flexibility of loading and unloading. It should be noted that the number and specific arrangement of the safety gratings 600 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.
