DETAILED DESCRIPTION

[0018] The present invention Figure 1 As shown in FIG. 6 , a discharge limiting mechanism for core winding includes a mounting seat 10, a discharge block 20 for placing the core 30, a limiting assembly 40 for limiting the core 30 on the discharge block 20, a positioning assembly 50 for positioning the limiting assembly 40, and a pushing assembly 60 for pushing the discharge block 20 so that the core 30 corresponds to the limiting assembly 40, wherein: The discharge block 20 can be movably arranged on the mounting seat 10; the limit assembly 40 has a flippable limit block 44, and the limit block 44 can be rotatably arranged on the front side of the mounting seat 10; the positioning assembly 50 is located on the front side of the mounting seat 10, and the positioning assembly 50 corresponds to the limit block 44; the push assembly 60 is connected to the discharge block 20, and the push assembly 60 drives the discharge block 20 to move so that the iron core 30 abuts against the limit block 44.

[0019] By adopting the discharge block 20, the limit assembly 40, the positioning assembly 50 and the push assembly 60, the discharge of the iron core 30, the limit of the iron core 30, the positioning of the limit assembly 40, and the push position movement of the iron core 30 are automatically realized, thereby meeting the position requirements and limit requirements of the iron core 30; by adopting the reversible limit block 44, the limit of the iron core 30 on the discharge block 20 is realized. At the same time, when the iron core 30 needs to be taken out from the discharge block 20, the limit block 44 is flipped at an angle to release the limit on the iron core 30 to avoid position interference; by adopting the push assembly 60, the synchronous push of the discharge block 20 and the iron core 30 is realized, so that the position of the discharge block 20 corresponds to that of the limit block 44. At the same time, the iron core 30 on the discharge block 20 is driven to move and then abut against the limit block 44, thereby limiting the position of the iron core 30 on the discharge block 20, facilitating subsequent winding operations, and ensuring the accuracy of the position of the iron core 30.

[0020] The iron core 30 winding material discharging and limiting mechanisms are divided into two groups, and the two groups of the iron core 30 winding material discharging and limiting mechanisms are symmetrically distributed.

[0021] The lower surface of the iron core 30 has a dovetail groove 31, and the middle position of the upper surface of the discharge block 20 protrudes upward to form a protrusion 22 matching the dovetail groove 31. The iron core 30 is detachably connected to the discharge block 20 through the dovetail groove 31 and the protrusion 22; the dovetail groove 31 and the protrusion 22 facilitate the detachable connection of the iron core 30 to the discharge block 20, which is easy to operate.

[0022] The discharge block 20 has a first inclined surface 21, and the limit block 44 has a second inclined surface 45 matching the first inclined surface 21. The discharge block 20 is in contact with the limit block 44 through the first inclined surface 21 and the second inclined surface 45. The first inclined surface 21 and the second inclined surface 45 are used to achieve precise position limitation of the discharge block 20 and the limit block 44, thereby ensuring the accuracy of the limit block 44 in limiting the discharge block 20.

[0023] The limit assembly 40 also includes a limit driving cylinder 41, a connecting rod 42 and a rotating shaft 43. The limit driving cylinder 41 is movably arranged on the mounting base 10. The lower end of the connecting rod 42 is hinged to the output end of the limit driving cylinder 41. The upper end of the connecting rod 42 is firmly connected to the rotating shaft 43. The rotating shaft 43 is rotatably located on the mounting base 10. The limit block 44 is firmly connected to the rotating shaft 43.

[0024] Before the iron core 30 is placed on the discharge block 20, the limit driving cylinder 41 drives the limit block 44 to flip the angle through the connecting rod 42 and the rotating shaft 43. The limit block 44 is located in front of the discharge block 20 and is spaced from the discharge block 20, which facilitates the operation of placing the iron core 30 on the discharge block 20 and avoids position interference; when the iron core 30 is placed on the discharge block 20, the limit block 44 flips the angle so that the limit block 44 is located in front of the discharge block 20 and close to the discharge block 20, and the push assembly 60 pushes the discharge block 20 and the iron core 30 so that the discharge block 20 corresponds to the position of the limit block 44, thereby realizing the limitation of the iron core 30.

[0025] The positioning assembly 50 includes a lifting drive cylinder 51 and a positioning block 52 . The positioning block 52 is installed on the shaft end of the lifting drive cylinder 51 . The positioning block 52 can be lifted and lowered to abut against the limit block 44 .

[0026] The lifting drive cylinder 51 drives the positioning block 52 to rise and fall. When the limit block 44 flips to the front side of the discharge block 20 and approaches the discharge block 20, the positioning block 52 rises and abuts against the side wall of the limit block 44, which is convenient for positioning the limit block 44, preventing the limit block 44 from shifting, and ensuring the position accuracy of the limit block 44.

[0027] The push assembly 60 includes a push drive device 61, a push plate 62, a first spring 63 and a second spring 64. The push drive device 61 is arranged on the mounting seat 10, and the push plate 62 is arranged at the output end of the push drive device 61. The first spring 63 is longitudinally connected between the discharge block 20 and the push plate 62, and the second spring 64 is vertically connected between the discharge block 20 and the mounting seat 10. The push drive device 61 drives the discharge block 20 to be movably corresponding to the limit block 44.

[0028] A guide post 14 is transversely arranged on the mounting seat 10 , and a guide groove 23 matching the guide post 14 is opened on the material discharging block 20 . The material discharging block 20 is movably sleeved on the guide post 14 through the guide groove 23 .

[0029] The push driving device 61 includes a push driving cylinder, which drives the push plate 62 to move longitudinally, and the push plate 62 drives the discharge block 20 to move longitudinally through the first spring 63; due to the guiding effect of the guide column 14 and the guide groove 23 and the action force of the second spring 64, the discharge block 20 moves downward, and the moving direction of the discharge block 20 is synchronous forward and downward movement, and the discharge block 20 drives the iron core 30 to move to the corresponding position of the limit block 44.

[0030] There are multiple discharge blocks 20, first springs 63 and second springs 64. The multiple discharge blocks 20 are evenly spaced and movably distributed laterally on the mounting seat 10. The multiple first springs 63 are connected to the push plate 62, and the multiple first springs 63 correspond to the multiple discharge blocks 20 one by one. The multiple second springs 64 are connected to the mounting seat 10, and the multiple second springs 64 correspond to the multiple discharge blocks 20 one by one.

[0031] By providing a plurality of discharge blocks 20, first springs 63 and second springs 64, it is convenient to discharge and limit a plurality of iron cores 30 at the same time, which is convenient for subsequent synchronous winding and improves work efficiency.

[0032] The mounting seat 10 has a mounting block 11 for mounting a discharge block 20, and a receiving groove 12 for receiving a first spring 63 is provided on the mounting block 11. The receiving groove 12 is multiple, and the multiple first springs 63 correspond to the multiple receiving grooves 12 one by one. The front side of the mounting block 11 is evenly spaced with opening gaps 13 corresponding to the discharge block 20, and the discharge block 20 is movably located at the position of the opening gap 13.

[0033] The accommodating groove 12 is used to facilitate the installation of the first spring 63 , and the opening gap 13 is used to facilitate the installation and position movement of the material discharging block 20 , thereby meeting the position movement requirements of the material discharging block 20 .

[0034] The operating method of the material discharging limiting mechanism for core winding comprises the following steps: First, the iron core is placed on the material discharging block, and the limit block of the limit assembly is turned over so that the limit block is located at the front side of the iron core; Second, the positioning assembly positions the limit block to ensure that the position of the limit block remains unchanged during the process of limiting the core; Third, the push assembly drives the discharge block and the iron core to move synchronously, so that the discharge block corresponds to the limit block, the iron core on the discharge block abuts against the limit block, and the limit block limits the iron core.

[0035] The design focus of the present invention is that the discharge of the iron core, the limitation of the iron core, the positioning of the limit assembly, and the pushing position movement of the iron core are automatically realized by adopting a discharge block, a limit assembly, a positioning assembly and a push assembly, thereby meeting the position requirements and limit requirements of the iron core; the limitation of the iron core on the discharge block is realized by adopting a flippable limit block. At the same time, when the iron core needs to be taken out from the discharge block, the limit block flips the angle to release the limitation on the iron core to avoid position interference; the synchronous push of the discharge block and the iron core is realized by adopting a push assembly, so that the position of the discharge block and the limit block corresponds to each other. At the same time, the iron core on the discharge block is driven to move and then abut against the limit block, thereby limiting the position of the iron core on the discharge block, facilitating subsequent winding operations, and ensuring the accuracy of the core position.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
