[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: according to Figures 1-7 The stacking platform shown has stepless adjustable hole spacing and includes at least a stacking platform body 1, a positioning pin seat 2, and a positioning pin 3; multiple positioning pin seats 2 are provided, and multiple positioning pin seats 2 are detachably connected to preset positions on the upper surface of the stacking platform body 1; each positioning pin seat 2 is detachably provided with a positioning pin 3.

[0029] In practical use, according to the different hole spacing on the transformer core 14, multiple positioning pin seats 2 are set at different positions on the stacking body 1 and fixed. Thus, the positioning pins 3 set on each positioning pin seat 2 are used to position and stack the transformer core 14. This is not only simple and convenient, but also allows for stepless adjustment of the positioning pin spacing for different hole spacings of the transformer core 14. It has high positioning accuracy and reliable fixing status.

[0030] In some embodiments, the stacking platform body 1 includes a platform and a base; the base is connected to the lower surface of the platform and can fix the platform through the base; the platform is made of iron material; the positioning pin seat 2 is detachably connected to the platform by magnetic attraction.

[0031] In actual use, the stack body 1 is fixed by the base, and the positioning pin seat 2 is connected to the platform by magnetic attraction, making it easier to steplessly adjust the positioning pin spacing for different transformer core hole spacings.

[0032] In some embodiments, the stacking platform body 1 is an iron tray; the positioning pin seat 2 is detachably connected to the iron tray by magnetic attraction.

[0033] The stacking platform body 1 adopts an iron tray, which allows for more flexible installation and transfer. It is convenient to use when the installation position of the stacking platform with stepless adjustable hole spacing is different from the stacking position of the transformer core 14.

[0034] In some embodiments, the positioning pin holder 2 includes a base 4 and a conductive terminal 5; the conductive terminal 5 is connected to the top of the base 4; and an electromagnet 6 is connected to the bottom of the base 4.

[0035] Furthermore, the base 4 is composed of an upper cylinder 11 and a lower cylinder 12 with different outer diameters. The outer diameter of the upper cylinder 11 is smaller than that of the lower cylinder 12, the length of the upper cylinder 11 is greater than that of the lower cylinder 12, and the upper cylinder 11 and the lower cylinder 12 have through holes along the central axis.

[0036] In actual use, the positioning pin holder 2 is attracted to the platform surface of the stack body 1 by the electromagnet 6. It retains its magnetism even after power is off, firmly fixing the positioning pin holder 2 in place. The base 4 adopts the above structure, which makes the positioning pin holder 2 more stable and allows for easy connection of the positioning pin 3.

[0037] Example 2: Reference Figure 1-5 , Figure 7 A stacking system with steplessly adjustable hole spacing includes at least stacking platforms with steplessly adjustable hole spacing, a CNC system, a linear module 9, and a gripper 8; multiple sets of stacking platforms with steplessly adjustable hole spacing are arranged in a straight line; the linear module 9 is located next to the multiple sets of stacking platforms with steplessly adjustable hole spacing; the gripper 8 is connected to the linear module 9; when the linear module 9 moves, the gripper 8 moves to above each stacking platform with steplessly adjustable hole spacing; the CNC system is electrically connected to the linear module 9 and the gripper 8 respectively.

[0038] Furthermore, the linear module 9 is a gantry-type linear module, capable of moving up and down, forward and backward, and left and right; the gripper 8 is a pneumatic gripper, with a conductive ring 13 connected to the middle of its bottom; the CNC system includes at least a data acquisition module, an analysis module, and a signal transmission module; the analysis module is electrically connected to the linear module 9 and the gripper 8 through the data acquisition module to acquire position information data of the linear module 9 and the gripper 8; the analysis module is electrically connected to the signal transmission module to transmit control signals to the signal transmission module to implement operation control of the linear module 9 and the gripper 8.

[0039] Furthermore, the linear module 9 is replaced by an articulated robot.

[0040] In practical use, when the installation station of the infinitely adjustable hole spacing stack is the same as the stacking station of the transformer core 14, the infinitely adjustable hole spacing stack is fixed to the ground of the station by the base of the stack body 1. The CNC system can drive the linear module or articulated robot 9 to accurately move the positioning pin seat 2 gripped by the gripper 8 to the required position according to the specifications of the transformer core 14. After placing it in the corresponding preset position on the table of the stack body 1, the control system controls the gripper 8 to separate from the positioning pin seat 2. At this time, the de-energized electromagnet 6 generates magnetism, firmly fixing the positioning pin seat 2 to the table of the stack body 1, and the operator can perform the stacking operation of the transformer core 14.

[0041] The system has high positioning accuracy and reliable fixation, and can meet the automatic or manual stacking requirements of transformer core 14, promoting the intelligent manufacturing of transformer cores.

[0042] The numerical control system in this embodiment uses a PLC controller based on existing technology.

[0043] The electromagnet 6 in this embodiment is a power-off retention type electromagnet.

[0044] The linear module 9 in this embodiment uses existing technology and can move forward, backward, up, down, left, and right.

[0045] In practical applications, guide rails can be installed on the bottom of the articulated robot as needed to increase its coverage area.

[0046] Example 3: Reference Figure 1-4 , Figure 6 and Figure 7 A stacking system with steplessly adjustable hole spacing includes at least a stacking platform with steplessly adjustable hole spacing, a CNC system, a linear module 9, a roller conveyor or AGV 10, and a gripper. The linear module 9 is a gantry-type linear module, capable of vertical, horizontal, and back-and-forth movement. The gripper 8 is a pneumatic gripper, with a conductive ring 13 connected to the middle position of its bottom. The roller conveyor or AGV 10 is positioned beside the stacking platform with steplessly adjustable hole spacing to transport the assembled stacking platform to the stacking station of the transformer core 14, and to remove any uninstalled positioning pin seats 2. The iron pallet, serving as the stacking platform body 1, is transported to the workstation where the positioning pin seat 2 is placed. The CNC system includes at least a data acquisition module, an analysis module, and a signal transmission module. The analysis module is electrically connected to the linear module 9, the gripper 8, and the roller conveyor or AGV 10 via the data acquisition module to acquire position information data of the linear module 9, the gripper 8, and the roller conveyor or AGV 10. The analysis module is electrically connected to the signal transmission module to transmit control signals to the signal transmission module, thereby implementing operation control of the linear module 9, the gripper 8, and the roller conveyor or AGV 10.

[0047] In practical use, when the installation station of the infinitely adjustable hole spacing stack is located at a different location from the stacking station of the transformer core 14, the stack body 1 uses a movable pallet. The empty stack body 1 is transferred to the fixed stack installation station via a roller conveyor or AGV 10. The CNC system can drive the linear module or articulated robot 9 to accurately move the positioning pin seat 2 gripped by the gripper 8 to the required position according to the specifications of the transformer core 14. After the positioning pin seat 2 is placed in the corresponding preset position on the table of the stack body 1, the control system controls the gripper 8 to separate from the positioning pin seat 2. At this time, the de-energized electromagnet 6 generates magnetism and firmly fixes the positioning pin seat 2 on the table of the stack body 1. Afterwards, the PLC controller sends a command to the roller conveyor (or AGV) to transfer the installed infinitely adjustable hole spacing stack to the lamination station.

[0048] AGV is an abbreviation for Automated Guided Vehicle, which stands for Intelligent Handling Robot.

[0049] The numerical control system in this embodiment uses a PLC controller, which is used to control the operation of the roller conveyor or AGV10.

[0050] By adopting this technical solution, the assembly line for installing transformer core 14 can be reduced, the space occupied by the equipment can be reduced, and the cost can be lowered.
