[0048] The detailed description of the application is described in detail below in combination with the accompanying drawings. It should be understood that the detailed description described herein is only used to illustrate and explain the application, and is not used to limit the application.

[0049] Referring to Figures 1 to 8 , the application provides a plate positioning system, which comprises:

[0050] a primary positioning material frame 1, comprising a material frame base 11 for placing a half-split splice plate 41 of a frog-shaped plate 4, a material frame transverse positioning structure 12 arranged on the material frame base 11 and used for positioning the half-split splice plate 41 in the transverse direction, and a material frame longitudinal positioning structure 13 arranged on the material frame base 11 and used for positioning the half-split splice plate 41 in the longitudinal direction;

[0051] a secondary positioning gantry 2, comprising a gantry base 21, a gantry inclined platform 22 supported by the gantry base 21 and used for placing the half-split splice plate 41 in an inclined manner relative to the horizontal plane, a platform transverse limiting structure 23 arranged on the gantry inclined platform 22 and used for limiting the half-split splice plate 41 in the transverse direction, and a platform longitudinal limiting structure 24 arranged on the gantry inclined platform 22 and used for limiting the half-split splice plate 41 in the longitudinal direction; and

[0052] a carrying robot 3 capable of carrying the half-split splice plate 41 positioned by the primary positioning material frame 1 to the gantry inclined platform 22, so that the half-split splice plate 41 can slide along the gantry inclined platform 22 to be jointly limited by the platform transverse limiting structure 23 and the platform longitudinal limiting structure 24.

[0053] Through the above arrangement, the plate positioning system of the present application can realize the one-time positioning of the half-spliced plates 41 by positioning the material frame 1 storing a plurality of frog-shaped plate materials 4 to be processed, and can realize the one-time positioning of the half-spliced plates 41 by using the material frame transverse positioning structure 12 and the material frame longitudinal positioning structure 13, so as to ensure that the handling robot 3 can take out the one-time positioned half-spliced plates 41 from the one-time positioning material frame 1 every time under the preset motion path, and then put them into the secondary positioning gantry 2.

[0054] The half-spliced plates 41 put into the secondary positioning gantry 2 can slide along the gantry inclined platform 22 under the action of their own gravity until they are jointly limited by the platform transverse limiting structure 23 and the platform longitudinal limiting structure 24, thereby realizing secondary positioning. In this way, each half-spliced plate 41 put into the secondary positioning gantry 2 can be positioned at the same position, so that the handling robot 3 can take out the half-spliced plates 41 from the secondary positioning gantry 2 every time through the same path and put them into the same station in the production line when the half-spliced plates 41 need to enter the production line for processing, thereby realizing automatic feeding of the half-spliced plates 41 and providing a basis for fully automated production of the frog-shaped plate materials 4.

[0055] It should be noted that, referring to Figure 9 , the frog-shaped plate material 4 is spliced by two half-spliced plates 41, so the two half-spliced plates 41 have the feature of mirror symmetry, and therefore two sets of one-time positioning material frames 1 and secondary positioning gantries 2 can be configured in the plate production line, that is, one set of one-time positioning material frame 1 and secondary positioning gantry 2 is used to realize positioning of one half-spliced plate 41, and the other set of one-time positioning material frame 1 and secondary positioning gantry 2 is used to realize positioning of the other half-spliced plate 41.

[0056] In some embodiments, referring to Figures 2 to 5 , the gantry inclined platform 22 can be inclined relative to the horizontal plane in the longitudinal and transverse directions, the platform transverse limiting structure 23 can include a plurality of belly limiting rods 23a arranged on the transverse lower side of the gantry inclined platform 22 and used to jointly abut and limit the inner side of the belly 41c of the half-spliced plate 41, and the platform longitudinal limiting structure 24 can include a plurality of leg limiting blocks 24a arranged on the longitudinal lower side of the gantry inclined platform 22 and used to abut and limit the leg 41d of the half-spliced plate 41.

[0057] Since the gantry inclined platform 22 is inclined relative to the horizontal plane in the longitudinal and transverse directions, when the half-spliced plate 41 slides along the gantry inclined platform 22, it can slide towards the plurality of belly limiting rods 23a and the plurality of leg limiting blocks 24a, and when the plurality of belly limiting rods 23a abut and limit the inner side of the belly 41c of the half-spliced plate 41 and the plurality of leg limiting blocks 24a abut and limit the leg 41d of the half-spliced plate 41, the half-spliced plate 41 stops sliding, thereby realizing secondary positioning.

[0058] Of course, the present application does not limit the specific structure of the platform transverse limiting structure 23 and the platform longitudinal limiting structure 24, i.e., it is not limited to the structure of the plurality of abdominal limiting rods 23a and the leg limiting blocks 24a described above, as long as it can stop the half-split panel 41 from sliding on the gantry tilting platform 22 to achieve secondary positioning.

[0059] In some embodiments, with reference to Figures 2 to 3 , the secondary positioning gantry 2 can further include a sliding-off guide seat 25 arranged on the gantry tilting platform 22, which is transversely spaced on the upper side of the abdominal limiting rod 23a and is provided with a guide inclined surface. After the handling robot 3 places the half-split panel 41 on the gantry tilting platform 22, the half-split panel 41 is in contact with the guide inclined surface of the sliding-off guide seat 25, which can ensure that the half-split panel 41 slides toward the plurality of abdominal limiting rods 23a and leg limiting blocks 24a under the guidance of the guide inclined surface, thereby ensuring that the half-split panel 41 is ultimately limited and positioned by the plurality of abdominal limiting rods 23a and leg limiting blocks 24a to complete secondary positioning.

[0060] In some embodiments, the secondary positioning gantry 2 can further include a plurality of auxiliary sliding-off structures arranged on the gantry tilting platform 22, which include a fixed plate 26 connected to the gantry tilting platform 22 and a universal ball 27 partially embedded in the fixed plate 26. After the handling robot 3 places the half-split panel 41 on the gantry tilting platform 22, the universal ball 27 can abut the panel surface of the half-split panel 41, thereby forming rolling contact with the half-split panel 41, so that the resistance to the half-split panel 41 when sliding is greatly reduced, thereby making it easier for the half-split panel 41 to slide and effectively reducing the panel surface wear of the half-split panel 41, better ensuring the surface quality of the half-split panel 41.

[0061] Of course, the universal ball 27 is not necessarily provided, because the frog-shaped panel 4 applied to the pump truck base frame originally has a relatively large weight, so the weight of the half-split panel 41 thereof is also relatively large, and therefore as long as the inclination of the gantry tilting platform 22 is properly set, it can ensure that the half-split panel 41 slides along the gantry tilting platform 22.

[0062] In some embodiments, the secondary positioning rack 2 can further include a plurality of support pads 28 arranged on the rack tilting platform 22 and used for supporting the plate surface of the half-spliced plate 41, which can avoid the direct contact between the half-spliced plate 41 and the surface of the rack tilting platform 22, for example, the support pads 28 can be elastic pads or other pads with cushioning protection, which is conducive to reducing the wear of the plate surface of the half-spliced plate 41. In the case of simultaneously arranging the universal ball 27 and the support pad 28, the half-spliced plate 41 can be substantially parallel to the surface of the rack tilting platform 22, so as to avoid the edge of the half-spliced plate 41 from colliding with the surface of the rack tilting platform 22.

[0063] In some embodiments, the secondary positioning rack 2 can further include a tilting degree adjusting structure connecting the rack base 21 and the rack tilting platform 22, which is used for adjusting the tilting degree of the rack tilting platform 22, so as to ensure that the half-spliced plates 41 with different sizes and weights can be slid on the rack tilting platform 22, and avoid the situation that the half-spliced plate 41 cannot be positioned due to the stop of the half-spliced plate 41 on the rack tilting platform 22 before being limited by the platform transverse limiting structure 23 and the platform longitudinal limiting structure 24. By arranging the tilting degree adjusting structure, the applicability of the secondary positioning rack 2 to the half-spliced plates 41 with different sizes and weights can be improved.

[0064] In some embodiments, referring to Figure 2 and Figure 6 , the tilting degree adjusting structure can include a hinged seat 29, a fish-eye joint 210, a screw rod 211, an adjusting nut 212 and a tension nut 213.

[0065] Specifically, the hinged seat 29 is connected to the rack tilting platform 22, the hinged end of the fish-eye joint 210 is hinged to the hinged seat 29, and the internally threaded end of the fish-eye joint 210 is threadedly connected to the top of the screw rod 211. In addition, the adjusting nut 212 is threadedly connected to the shank of the screw rod 211, the rack base 21 is provided with a base through hole, the bottom of the screw rod 211 passes through the base through hole downwardly and is threadedly connected to the tension nut 213.

[0066] Through the arrangement of the embodiment, the tilting degree adjusting structure can adjust the tilting degree of the rack tilting platform 22 by adjusting the number of the adjusting nuts 212 connected to the screw rod 211. When it is needed to increase or decrease the number of the adjusting nuts 212, the tension nut 213 needs to be screwed out of the screw rod 211, then the screw rod 211 needs to be pulled out of the base through hole of the rack base 21, and then the adjusting nuts 212 need to be screwed into or out of the screw rod 211, so as to adjust the number of the adjusting nuts 212. After adjusting the number of the adjusting nuts 212, the bottom of the screw rod 211 passes through the base through hole downwardly and is locked by the tension nut 213. After completing the above operations, the rack tilting platform 22 can have a new tilting degree.

[0067] In some embodiments, the secondary positioning gantry 2 can further include a lifting ring 214 arranged on the gantry tilting platform 22. In the above-mentioned manner of adjusting the inclination of the gantry tilting platform 22 by increasing or decreasing the number of adjusting nuts 212, the gantry tilting platform 22 needs to be in a suspended state without being supported by the gantry base 21 when performing operations such as pulling the screw rod 211 out of the base through hole of the gantry base 21, screwing or unscrewing the adjusting nuts 212 on the screw rod 211, etc. Therefore, the embodiment is characterized in that the lifting ring 214 is arranged on the gantry tilting platform 22. In this way, the gantry tilting platform 22 can be temporarily lifted by using hoisting equipment and cooperating with the lifting ring 214, so that the gantry tilting platform 22 is in a suspended state, thereby reducing the difficulty of adjusting the number of adjusting nuts 212, reducing the labor, and improving the adjustment efficiency.

[0068] In some embodiments, referring to Figure 7 and Figure 8 , the material frame transverse positioning structure 12 can include an abdomen positioning seat 12a and a head positioning seat 12b arranged on the transverse edge of the material frame base 11 and used for abutting and positioning the inner side of the abdomen 41c and the inner side of the head 41a of the half-spliced plate 41, respectively. The material frame longitudinal positioning structure 13 can include a head positioning pin 13a and a tail positioning pin 13b arranged along the longitudinal direction of the material frame base 11 and used for abutting and positioning the head 41a and the tail 41b of the half-spliced plate 41, respectively. In addition, the primary positioning material frame 1 further includes a positioning distance adjusting structure arranged on the material frame base 11 and used for adjusting the longitudinal distance between the head positioning pin 13a and the tail positioning pin 13b.

[0069] Through the arrangement of the embodiment, after the half-spliced plate 41 is placed into the material frame base 11, the inner side of the abdomen 41c of the half-spliced plate 41 can be positioned by abutting against the abdomen positioning seat 12a, and the inner side of the head 41a of the half-spliced plate 41 can be positioned by abutting against the head positioning seat 12b, thereby realizing the transverse positioning of the half-spliced plate 41.

[0070] In addition, by adjusting the longitudinal distance between the head positioning pin 13a and the tail positioning pin 13b through the positioning distance adjusting structure, the head positioning pin 13a can abut and position the head 41a of the half-spliced plate 41, and the tail positioning pin 13b can abut and position the tail 41b of the half-spliced plate 41, thereby realizing the longitudinal positioning of the half-spliced plate 41 with different longitudinal dimensions. It can be seen that the embodiment is beneficial to improve the applicability of the primary positioning material frame 1 to half-spliced plates 41 with different sizes.

[0071] Of course, the present application does not limit the specific structure of the transverse positioning structure 12 and the longitudinal positioning structure 13, i.e., does not limit the structure of the abdominal positioning seat 12a, the head positioning seat 12b, the head positioning pin 13a and the tail positioning pin 13b as described above, as long as the once-positioned half-joining plate 41 can be positioned on the once-positioned material frame 1.

[0072] In some embodiments, the positioning distance adjustment structure can include a first sliding fitting structure and a second sliding fitting structure, wherein the first sliding fitting structure includes a first sliding groove 14 extending along the longitudinal direction of the material frame base 11 and a first sliding block 15 slidingly fitted with the first sliding groove 14 and connected with the head positioning pin 13a, and the second sliding fitting structure includes a second sliding groove 16 extending along the longitudinal direction of the material frame base 11 and a second sliding block 17 slidingly fitted with the second sliding groove 16 and connected with the tail positioning pin 13b.

[0073] By sliding the first sliding block 15 in the first sliding groove 14, the position of the head positioning pin 13a connected with the first sliding block 15 in the longitudinal direction of the material frame base 11 can be achieved, and by sliding the second sliding block 17 in the second sliding groove 16, the position of the tail positioning pin 13b connected with the second sliding block 17 in the longitudinal direction of the material frame base 11 can be achieved. In this way, the longitudinal distance between the head positioning pin 13a and the tail positioning pin 13b can be quickly adjusted conveniently.

[0074] In some embodiments, the once-positioned material frame 1 can further include an elastic pad 18 arranged on the material frame base 11 and used for supporting the half-joining plate 41, which can avoid the rigid collision between the half-joining plate 41 and the material frame base 11, and is beneficial to reduce the risk of wear of the half-joining plate 41.
