Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer production equipment technology, and in particular to a transformer core assembly equipment. Background Technology
[0002] In the manufacturing process of transformer core, the core clamps are first placed on the assembly table, and then the silicon steel sheets are stacked on the clamps and spliced flat. After the silicon steel sheets of the core are assembled, the entire core is fixed and locked by the clamps. Then, the core is erected on the ground or on a trolley by a turning machine. When installing the coil winding, the upper pressure piece needs to be opened, and then the silicon steel sheets of the upper yoke are removed one by one. After the upper yoke is removed, the coil winding is put on the core. After the coil winding is installed, the silicon steel sheets of the upper yoke are assembled one by one.
[0003] In traditional production techniques, the stacking of upper yoke silicon steel sheets is generally achieved manually. Traditional manual stacking is labor-intensive and slow, severely impacting production efficiency. It also easily leads to problems such as misalignment and uneven spacing, making it difficult to guarantee stacking accuracy and consistency, and affecting the magnetic circuit performance and mechanical strength of the iron core.
[0004] In existing transformer core assembly equipment, after the transformer core is fixed by a core fixing device, a robotic arm moves the upper yoke silicon steel sheets to complete the winding installation, and then the robotic arm reinstalls the upper yoke silicon steel sheets. However, in these assembly devices, the picking and placing positions of each upper yoke silicon steel sheet are different, and the robotic arm picks and places them at different positions each time, which places high demands on debugging and control, and is also costly.

[0030] Reference Figures 1 to 3 The transformer core assembly equipment of this utility model is illustrated in the following embodiments:
[0031] A transformer core assembly device includes: a receiving device 200, a core fixing device 300, and a picking and placing device 400.
[0032] The receiving device 200 includes a storage channel 210 and a receiving mechanism 220. The storage channel 210 is used to store multiple upper yoke silicon steel sheets. The receiving mechanism 220 includes a receiving and transferring drive component 221 and multiple clamping blocks 222. The receiving and transferring drive component 221 is used to drive the multiple clamping blocks 222 to move along a closed-loop path. The multiple clamping blocks 222 are arranged at intervals along the closed-loop path, and adjacent two clamping blocks 222 form a receiving slot 223. At least one section of the closed-loop path is located on one side of the storage channel 210 and extends along the storage channel 210.
[0033] The core fixing device 300 is used to fix the transformer core, and the picking and placing device 400 is used to drive the upper yoke silicon steel sheet to move, so that the upper yoke silicon steel sheet is moved between the transformer core and the material storage channel 210.
[0034] In practical use, the transformer core can be fixed by the core fixing device 300, thereby enabling the transfer of the upper yoke silicon steel sheets between the transformer core and the storage channel 210 via the pick-and-place device 400. The pick-and-place device 400 can move the upper yoke silicon steel sheets from the transformer core into the storage channel 210, and also move the upper yoke silicon steel sheets from the storage channel 210 onto the transformer core. The upper yoke silicon steel sheets can be secured in the receiving slot 223 for positioning within the storage channel 210. The receiving and transferring drive component 221 can move the upper yoke silicon steel sheets and the locking block 222 within the storage channel 210, ensuring that each upper yoke silicon steel sheet can be picked up and placed in the same position. The transformer core assembly equipment of this utility model drives the upper yoke silicon steel sheet to move stepwise in the storage channel 210 through the receiving mechanism 220. The picking and placing position of the upper yoke silicon steel sheet in the storage channel 210 can be relatively fixed, which greatly reduces the difficulty of debugging and control of the picking and placing device 400 in picking and placing materials.
[0035] The picking and placing device 400 includes a picking and placing gripper 410 and a picking and placing drive mechanism 420. The picking and placing gripper 410 is used to adsorb or clamp the upper yoke silicon steel sheet, and the picking and placing drive mechanism 420 is used to drive the picking and placing gripper 410 to move between the storage channel 210 and the iron core fixing device 300.
[0036] In this embodiment, the material handling gripper 410 is equipped with multiple vacuum suction cups. The arrangement of these vacuum suction cups is tailored to the shape and size of the upper yoke silicon steel sheet. The upper yoke silicon steel sheet is adsorbed by the multiple vacuum suction cups, thereby achieving transfer. The specific installation structure of the vacuum suction cups is similar to that of existing vacuum suction grippers, and will not be detailed here.
[0037] The pick-and-place drive mechanism 420 includes a transverse drive component 421 arranged in the front-to-back direction and a longitudinal drive component 422 arranged in the up-and-down direction. The transverse drive component 421 and the longitudinal drive component 422 are respectively used to drive the pick-and-place gripper 410 to move in the front-to-back direction and the up-and-down direction. The transverse drive component 421 and the longitudinal drive component 422 can be linear drive components such as cylinders, electric push rods, hydraulic push rods, or lead screw and nut drive assemblies. In some other embodiments, the pick-and-place drive mechanism 420 can also be a four-axis robot or a six-axis robot, by mounting the pick-and-place gripper 410 to the working end of the robot to realize the movement, rotation and other functions of the pick-and-place gripper 410.
[0038] In this embodiment, the receiving device 200 is located on the upper side of the iron core fixing device 300, and the storage channel 210 extends in the front-back direction.
[0039] In some embodiments, there is one receiving mechanism 220, which is located on the lower side of the storage channel 210. The lower side of the storage channel 210 is formed by a plurality of receiving slots 223 arranged in a front-to-back manner. The upper yoke silicon steel sheet can be placed in the receiving mechanism 220, and the lower end of the upper yoke silicon steel sheet is inserted into the receiving slot 223, thereby causing the upper yoke silicon steel sheet to shift within the storage channel 210.
[0040] In this embodiment, there are two receiving mechanisms 220, which are arranged in pairs on the left and right sides of the storage channel 210. The two receiving mechanisms 220 arranged in left-right pairs can form movable receiving slots 223 on the left and right sides of the storage channel 210. The left and right ends of the same upper yoke silicon steel sheet are respectively engaged in the paired receiving slots 223, ensuring that the upper yoke silicon steel sheet is subjected to uniform force, thereby maintaining stability during movement within the storage channel 210.
[0041] In this embodiment, the material receiving and transferring drive component 221 adopts a synchronous belt drive assembly driven by a servo motor. The material receiving and transferring drive component 221 includes a synchronous belt and two synchronous pulleys. The two synchronous pulleys are arranged at a distance from each other and are rotatably arranged. The synchronous belt drive is wound around the two synchronous pulleys.
[0042] Furthermore, to enable the two receiving mechanisms 220 to operate synchronously, a transmission shaft is provided between the two receiving and transferring drive components 221. The two ends of the transmission shaft are respectively connected to the synchronous pulleys of the two receiving and transferring drive components 221. When the servo motor drives one of the synchronous pulleys to rotate, the two receiving and transferring drive components 221 operate synchronously, causing the upper yoke silicon steel sheet to move back and forth within the storage channel 210.
[0043] In other embodiments, the material receiving and transferring drive component 221 may also be a chain drive assembly or other forms of transmission assembly. Similarly, the drive element may also be a rotary drive element other than a servo motor, such as a rotary cylinder, servo motor, stepper motor, or pneumatic motor, depending on the requirements.
[0044] The locking block 222 in this embodiment is made of a soft material. Specifically, the locking block 222 can be made of materials such as rubber, POM engineering plastic, acrylic, or bakelite. If the upper yoke silicon steel sheet collides with the locking block 222 due to misoperation, the lower strength of the locking block 222 can reduce the damage to the upper yoke silicon steel sheet.
[0045] In this embodiment, the storage channel 210 is a cuboid extending front to back. The two receiving mechanisms 220, arranged left and right, can avoid the vertical alignment space of the receiving slots 223, allowing the upper yoke silicon steel sheet to be inserted or removed from the receiving slots 223 in the vertical direction. The rear end of the storage channel 210 has an inlet / outlet station, with an inlet / outlet port 211 on its lower side. A baffle plate 212 and a pick-and-place clearance hole 214 are provided on the rear side of the inlet / outlet station. The pick-and-place clearance hole 214 allows the pick-and-place gripper 410 to move.
[0046] Specifically, the pick-and-place clearance hole 214 is aligned front to back with the storage channel 210 and extends downwards. The pick-and-place gripper 410 can adsorb the rear side of the upper yoke silicon steel sheet in the inlet / outlet station. The pick-and-place clearance hole 214 can provide the pick-and-place gripper 410 with room to move, so that the pick-and-place gripper 410 can pull the upper yoke silicon steel sheet downwards from the inlet / outlet station from the inlet / outlet port 211, or pull the upper yoke silicon steel sheet upwards from the inlet / outlet port 211 into the inlet / outlet station.
[0047] The baffle plates 212 are arranged in pairs on the left and right sides of the pick-up and drop-off clearance holes 214 to limit the left and right ends of the upper yoke silicon steel sheet and prevent it from falling backward from the storage channel 210. To avoid obstructing the locking block 222 of the receiving mechanism 220, the baffle plate 212 is provided with a clearance groove 213. When the locking block 222 moves along its trajectory, it can pass through the clearance groove 213.
[0048] In a further embodiment, a third receiving mechanism 220 may be provided on the upper side of the material storage channel 210, and the upper end of the upper yoke silicon steel sheet is positioned by the receiving slot 223 of the receiving mechanism 220 provided on the upper side.
[0049] Furthermore, the receiving device 200 is adjustable in the front-to-back direction. By adjusting the position of the receiving device 200 in the front-to-back direction, the inlet / outlet port 211 can be aligned with the installation position of each upper yoke silicon steel sheet. The picking and placing device 400 can directly pull the upper yoke silicon steel sheet down from the inlet / outlet port 211 and move it to the installation position, or lift the upper yoke silicon steel sheet up from the upper end of the transformer core and insert it directly into the inlet / outlet station from the inlet / outlet port 211.
[0050] The transformer core assembly equipment of this embodiment also includes a base frame 100. The base frame 100 includes a base 110, a vertical frame 120, and a top support 130. The top support 130 is spaced above the base 110 to form a space between the top support 130 and the base 110 for placing the transformer core. The vertical frame 120 is located between the top support 130 and the base 110, and its upper and lower ends are fixedly connected to the top support 130 and the base 110, respectively. The core fixing device 300 is located on the rear side of the vertical frame 120, and the receiving device 200 and the picking and placing device 400 are both installed on the top support 130.
[0051] The receiving device 200 is provided with a sliding seat, which is slidably connected to the top support 130 in the front-back direction. The storage channel 210 and the receiving mechanism 220 are both installed on the sliding seat, and the picking and placing device 400 is connected to the sliding seat. The top support 130 is provided with a positioning drive mechanism for driving the receiving device 200 to move back and forth relative to the iron core fixing device 300. The positioning drive mechanism has a positioning drive end that is pulsatorically connected to the sliding seat and causes the sliding seat to move back and forth relative to the base frame 100.
[0052] In this embodiment, the pick-and-place device 400 and the sliding seat are slidably connected via a linear slide rail arranged in the front-to-back direction. In other embodiments, the pick-and-place device 400 and the sliding seat may also be slidably connected using a groove structure or other structures. The alignment drive mechanism may be a linear drive component such as an electric push rod, a hydraulic push rod, or a lead screw and nut drive assembly. By driving the receiving device 200 to move through the alignment drive mechanism, the inlet / outlet 211 can be vertically aligned with the installation position of the upper yoke silicon steel sheet each time the upper yoke silicon steel sheet is picked up or placed in the storage channel 210. This simplifies the picking and placing action and greatly reduces the debugging requirements of the pick-and-place device 400.
[0053] To facilitate the insertion of the upper yoke silicon steel sheet into the storage channel 210 from the inlet / outlet 211, a guide portion with a narrow top and wide bottom, shaped like a trumpet, is provided on the lower side of the inlet / outlet 211.
[0054] The core fixing device 300 of this embodiment includes a clamping mechanism 310 for clamping and fixing the lower part of the transformer core. The clamping mechanism 310 is disposed on the base 110. The clamping mechanism 310 can be a quick clamp structure, which clamps the lower part of the transformer core through a linkage structure, or it can be a threaded driven clamping block, which achieves clamping by moving the clamping block through bolts.
[0055] The base 110 has a positioning baffle 111 at its front, and the clamping mechanism 310 is spaced apart from the positioning baffle 111. In actual use, the lower end of the transformer core is engaged between the positioning baffle 111 and the clamping mechanism 310. In a further embodiment, the clamping mechanism 310 is adjustable along the front-rear direction on the base 110 to accommodate transformer cores of different sizes and specifications.
