[0043] Please refer to Figure 1 , an embodiment of the present invention provides a loading and unloading positioning device 100 for transporting and positioning a box body, including a transmission component 10, a first limiting member 20, a second limiting member 30, and a lifting limiting member 40. The transmission component 10 is used to transport the box body along a first direction. The transmission component 10 includes a first area 11 and a second area 13, and the first area 11 and the second area 13 are arranged in sequence along the transporting direction of the transmission component 10. The first limiting member 20 is disposed at one end of the second area 13 away from the first area 11, and the first limiting member 20 is arranged along a second direction, and the second direction is perpendicular to the first direction. The second limiting member 30 is disposed at one end of the transmission component 10 along the second direction, and the second limiting member 30 is arranged along the first direction. The lifting limiting member 40 is disposed between the first area 11 and the second area 13, and the lifting limiting member 40 is arranged along the second direction. The lifting limiting member 40 can move along the vertical direction to abut against the box body.

[0044] In an embodiment of the present utility model, the transmission assembly 10 transports the box body fed from the first area 11 along the first direction to the second area 13 until it abuts against the first limiting member 20. The first limiting member 20 limits the box body along the first direction, and the second limiting member 30 limits the box body along the second direction. After the box body in the second area 13 moves into place, the lifting limiting member 40 rises, and the transmission assembly 10 continues to transport the box body along the first direction until the box body abuts against the lifting limiting member 40. The lifting limiting member 40 limits the box body along the first direction, and the second limiting member 30 limits the box body along the second direction, realizing automatic handling and positioning of the box body. In addition, the box bodies in the first area 11 and the second area 13 can use the same feeding device for feeding, without the need to set up two feeding devices to feed the box bodies in the first area 11 and the second area 13 respectively, or reduce the time for the feeding device to move and align with the second area 13, improving the transportation efficiency and reducing the transportation cost.

[0045] Specifically, there are many structures of the transmission assembly 10. The transmission assembly 10 can include structures such as a conveyor belt and conveyor rollers. As long as the transmission assembly 10 can transport the box body along the first direction, this application does not make specific restrictions.

[0046] It can be understood that during the panel processing process, usually one box body is needed to carry the panel to be processed to facilitate the picking and feeding of the panel, and another box body is needed to carry the processed panel. Therefore, the box bodies in the first area 11 and the second area 13 are respectively used to carry the box body to be processed and the processed box body. It can be understood that it can be that the box body in the first area 11 is used to carry the panel to be processed, and the box body in the second area 13 is used to carry the processed panel, or it can be that the box body in the first area 11 is used to carry the processed panel, and the box body in the second area 13 is used to carry the panel to be processed. This application does not make specific restrictions.

[0047] The first limiting member 20 is used to abut against the box body to limit the box body along the first direction. It can be understood that the transmission assembly 10 can maintain the transportation state to continuously transport the box body along the first direction to keep the box body in a state of abutting against the first limiting member 20, achieving a better positioning effect. It can be understood that there are many structures of the first limiting member 20. The first limiting member 20 can include a sheet metal part, and the first limiting member 20 can include an abutting block. This application does not make specific restrictions.

[0048] The second limiting member 30 is used to abut against the box body along the second direction to limit the box body along the second direction. It can be understood that there are many structures of the second limiting member 30. The second limiting member 30 can include structures such as a limiting block and a sheet metal part. This application does not make specific restrictions. It can be understood that the second limiting member 30 can limit the box body in the first area 11 along the second direction, and the second limiting member 30 can also limit the box body in the second area 13 along the second direction.

[0049] The lifting limit member 40 can be lifted and lower to limit the box body in the first area 11. It can be understood that the lifting limit member 40 can include driving devices such as motors and cylinders. The lifting limit member 40 can also include structures such as sheet metal parts and abutting blocks. As long as the lifting limit member 40 can be lifted and lower to limit the box body in the first area 11, the present application does not make specific restrictions. It can be understood that during the process of transporting the box body from the first area 11 to the second area 13, the lifting limit member 40 is in the lowered state to facilitate the passage of the box body.

[0050] Please refer to Figure 1 and Figure 2 In the embodiment of the present utility model, the loading and unloading positioning device 100 may further include a telescopic limit component 50. The telescopic limit component 50 and the second limit member 30 are respectively arranged at both ends of the transmission component 10 along the second direction. The telescopic limit component 50 is arranged along the first direction, and the telescopic limit component 50 can move in a direction close to or away from the second limit member 30 to clamp the box body along the second direction.

[0051] In this way, the telescopic limit component 50 can also clamp the box body with the second limit member 30 along the second direction, further strengthening the limitation of the box body and ensuring the accurate positioning of taking or placing the panel from the box body. In addition, the telescopic limit component 50 can also adapt to the limit requirements of box bodies of different sizes, that is, it can adapt to the positioning of different box bodies by adjusting the telescopic distance of the telescopic limit component 50, reducing the positioning cost of loading and unloading the box body.

[0052] It can be understood that there are many structures of the telescopic limit component 50. The telescopic limit component 50 can include driving devices such as motors and cylinders, and can also include guiding structures such as guide rails and lead screws. The present application does not make specific restrictions.

[0053] It is worth noting that the telescopic limit component 50 can be provided with a first guiding inclined surface. Along the conveying direction of the transmission component 10, the first guiding inclined surface is arranged in a direction close to the second limit member 30. In this way, it can guide the box body to gradually abut against the telescopic limit component 50, reducing the requirements for the feeding position of the box body. It can be understood that in a certain embodiment, the second limit member 30 can be provided with a second guiding inclined surface. Along the conveying direction of the transmission component 10, the second guiding inclined surface is arranged in a direction close to the telescopic limit component 50. In this way, it can guide the box body to gradually abut against the second limit member 30, reducing the requirements for the feeding position of the box body.

[0054] Further, please refer to Figures 1 to 4, the telescopic limit component 50 includes a frame body 51, an abutting member 53, a guiding connecting member 55 and an elastic member 57. The frame body 51 can move in a direction close to or away from the second limiting member 30. The abutting member 53 is arranged on one side of the frame body 51 close to the second limiting member 30. The guiding connecting member 55 connects the abutting member 53 and the frame body 51, and the guiding connecting member 55 guides the abutting member 53 to move in a direction close to or away from the frame body 51. Two ends of the elastic member 57 are respectively abutted against the frame body 51 and the abutting member 53 to provide an elastic force for the abutting member 53 to move away from the frame body 51.

[0055] Thus, during the process of the telescopic limit component 50 and the second limiting member 30 clamping the box body, the abutting member 53 will move in a direction close to the frame body 51 under the action of the box body, and the elastic member 57 is compressed to generate an elastic deformation to buffer the pressure of the telescopic limit component 50 on the box body, and avoid damage to the box body caused by excessive instantaneous pressure of the telescopic limit component 50 on the box body.

[0056] It can be understood that the telescopic limit component 50 may further include a telescopic guiding member, a telescopic driving member and other structures. The telescopic guiding member is arranged along the second direction to guide the frame body 51 to move along the second direction. The telescopic driving member is in transmission connection with the frame body 51 to drive the frame body 51 to move in a direction close to or away from the second limiting member 30.

[0057] It can be understood that there are many structures of the guiding connecting member 55. The guiding connecting member 55 may be a guiding connecting bolt. The guiding connecting bolt includes a bolt head and a bolt column. The bolt column includes a smooth shaft section and a threaded section. The smooth shaft section is located on one side of the bolt column close to the bolt head. The threaded end is in threaded connection with the abutting member 53, and the smooth shaft section penetrates through the frame body 51, and the bolt head is used for abutting against the side of the frame body 51 away from the abutting member 53.

[0058] Furthermore, please refer to Figure 3 and Figure 4 , the guiding connecting member 55 may include a rotating shaft 551 and a linear bearing 553. The linear bearing 553 is arranged on the side of the frame body 51 away from the abutting member 53. The rotating shaft 551 penetrates through the linear bearing 553 and the frame body 51 to be connected with the abutting member 53.

[0059] Thus, the rotating shaft 551 can move along the linear bearing 553 to guide the abutting member 53 to move in a direction close to or away from the frame body 51.

[0060] Please refer to Figure 2 and Figure 3 , in the embodiment of the present invention, the telescopic limit component 50 further includes an overpressure sensing sheet 58 and an overpressure sensor 59. The overpressure sensing sheet 58 is arranged on the abutting member 53, and the overpressure sensor 59 is arranged on the frame body 51. The overpressure sensing sheet 58 and the overpressure sensor 59 cooperate to detect the distance between the abutting member 53 and the frame body 51.

[0061] Thus, the overpressure sensing piece 58 and the overpressure sensor 59 cooperate to detect the distance between the abutting member 53 and the frame body 51. If the distance between the abutting member 53 and the frame body 51 is too large, it means that the elastic deformation of the elastic member 57 between the abutting member 53 and the frame body 51 exceeds a certain limit, that is, the pressure exerted by the abutting member 53 on the box body is too large, so as to timely stop applying too much pressure to the box body and avoid overpressure. In addition, such a setting can also meet the positioning requirements of boxes of different sizes. That is, the frame body 51 can move along the second direction until the overpressure sensing piece 58 and the overpressure sensor 59 give feedback, and the clamping of the box body can be achieved without manually adjusting the telescopic distance of the frame body 51 when positioning different boxes.

[0062] Please refer to Figure 5 and Figure 6 In the embodiment of the present utility model, the loading and unloading positioning device 100 further includes a plurality of first distance sensors 60. The plurality of first distance sensors 60 are arranged on the first limiting member 20, and the plurality of first distance sensors 60 are arranged along the second direction.

[0063] The loading and unloading positioning device 100 further includes a plurality of second distance sensors 70. The plurality of second distance sensors 70 are arranged on the lifting limiting member 40, and the plurality of second distance sensors 70 are arranged along the second direction.

[0064] Thus, the good abutment between the box body and the first limiting member 20 can be confirmed by the plurality of first distance sensors 60, and the good abutment between the box body and the lifting limiting member 40 can be confirmed by the plurality of second distance sensors 70, so as to ensure the positioning effect of the box body.

[0065] Please refer to Figure 1 、 Figure 7 and Figure 8 In the embodiment of the present utility model, the transmission component 10 includes a transmission driving member 15 and a roller group 17. The roller group 17 includes a mounting seat 171 and a plurality of rollers 173. The plurality of rollers 173 are rotatably connected to the mounting seat 171, and the plurality of rollers 173 are evenly arranged along the first direction. The transmission driving member 15 is in transmission connection with the roller group 17 to drive the plurality of rollers 173 to rotate.

[0066] Thus, the transmission driving member 15 drives the plurality of rollers 173 to roll, so as to drive the box body to move along the first direction.

[0067] Further, please refer to Figure 1 、 Figure 7 and Figure 8The transmission assembly 10 includes two roller groups 17, which are arranged along the second direction. The transmission drive member 15 includes a transmission motor 151, a transmission shaft 153 and a plurality of chains 155. The transmission motor 151 drives the transmission shaft 153 to rotate. The transmission shaft 153 is arranged along the second direction. The two ends of the transmission shaft 153 are respectively connected to the rollers 173 of the two roller groups 17 through the chains 155, and the adjacent rollers 173 are connected through the chains 155.

[0068] In this way, since the two roller groups 17 are arranged along the second direction, the two roller groups 17 are arranged side by side to jointly transport larger boxes. Compared with setting up a very long roller group 17 17 to transport boxes, the load-bearing requirements of the roller 173 are reduced. In addition, since the two roller groups 17 are driven by the same transmission drive member 15, not only the driving cost is reduced, but also the rotation of the two roller groups 17 can be kept synchronized to achieve a better transportation effect.

[0069] See also Figure 6 In the embodiment of the present invention, the lifting limit member 40 includes a lifting drive member 41, a lifting guide rail 43 and a lifting abutment member 45. The lifting guide rail 43 is arranged along the vertical direction. The lifting guide rail 43 connects the lifting drive member 41 and the lifting abutment member 45 to guide the lifting abutment member 45 to move along the vertical direction. The lifting drive member 41 and the lifting abutment member 45 are connected by a floating joint 47.

[0070] In this way, the lifting guide rail 43 guides the lifting abutment member 45 to move in the vertical direction, and the lifting driving member 41 drives the lifting abutment member 45 to move in the vertical direction, thereby achieving the lifting and lowering of the lifting abutment member 45 .

[0071] An embodiment of the present utility model also provides a processing equipment, which includes a feeding device and a loading and unloading positioning device 100. The feeding device is used to deliver the box body to the loading and unloading positioning device 100. The specific structure of the loading and unloading positioning device 100 refers to the above embodiment. Since this processing equipment adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0072] In the embodiment of the present utility model, the transmission component 10 transports the box body fed from the first area 11 along the first direction to the second area 13 until it abuts against the first limiting member 20. The first limiting member 20 limits the box body along the first direction, and the second limiting member 30 limits the box body along the second direction. After the box body in the second area 13 moves into place, the lifting limiting member 40 rises, and the transmission component 10 continues to transport the box body along the first direction until the box body abuts against the lifting limiting member 40. The lifting limiting member 40 limits the box body along the first direction, and the second limiting member 30 limits the box body along the second direction, realizing the automatic handling and positioning of the box body. In addition, the box bodies in the first area 11 and the second area 13 can use the same feeding device for feeding, without setting two feeding devices to feed the box bodies in the first area 11 and the second area 13 respectively, or reducing the time for the feeding device to move and align with the second area 13, improving the transportation efficiency and reducing the transportation cost.
