Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, specifically a stacking device for processing transformer cores. Background Technology

[0002] In the transformer manufacturing process, core processing is one of the key steps determining equipment performance. As the core magnetic circuit component for electromagnetic conversion in a transformer, the processing quality of the core directly affects the transformer's permeability, loss parameters, and operational stability. Furthermore, the core processing quality is highly dependent on the precision of the silicon steel sheet stacking process. Multiple silicon steel sheets of different specifications must be alternately aligned and stacked according to design requirements to ensure the core possesses good magnetic circuit performance. Currently, to improve stacking efficiency and reduce human error, the industry widely uses specialized stacking devices to assist in the handling, temporary storage, and stacking of silicon steel sheets. These devices have become common equipment in the large-scale production of transformer cores.

[0003] However, existing stacking devices still have significant technical shortcomings when dealing with scenarios where silicon steel sheets of different specifications are stacked alternately, making it difficult to meet the requirements of high-precision processing. Specifically, the lack of effective pre-positioning methods during the temporary storage stage of silicon steel sheets leads to positional shifts or inconsistent postures of silicon steel sheets of different specifications, posing potential accuracy risks for subsequent gripping and transfer.

[0004] To address this problem, a stacking device for transformer core processing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a stacking device for processing transformer cores, which has the advantage of improving the stacking accuracy of silicon steel sheets of different specifications and solves the problem of poor stacking quality caused by insufficient pre-positioning of silicon steel sheets in existing devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stacking device for processing transformer cores, comprising an adjusting mechanism, on which two temporary storage mechanisms are movably mounted via positioning frames. The two temporary storage mechanisms are used for temporary storage and pre-positioning of two different specifications of silicon steel sheets. A placement mechanism is movably arranged inside the adjusting mechanism, which receives the silicon steel sheets transferred by the adjusting mechanism and completes the stacking. The adjusting mechanism includes a support frame, on which a gripping and transferring component for gripping and transferring the silicon steel sheets is provided. The gripping and transferring component includes a slide mounted slidably on the support frame, a cylinder for driving the slide, and a gripping frame with a pneumatic suction cup. The temporary storage mechanism includes a base plate, on which a first positioning rod is vertically mounted. The first positioning rod is used for initially limiting the silicon steel sheets. A limiting frame is mounted on the base plate, used for limiting the silicon steel sheets. The base plate also has a structure for assisting in positioning the silicon steel sheets.

[0007] Preferably, in the gripping and transferring component of the adjustment mechanism, the slide includes a first slide and a second slide, a guide frame is installed on the support frame, the first slide and the second slide are slidably installed on the guide frame via a slide rod, the cylinder includes a longitudinal adjustment cylinder, a first lateral adjustment cylinder and a second lateral adjustment cylinder, two longitudinal adjustment cylinders are provided and are respectively installed on the first slide and the second slide, and the gripping frame is respectively installed on the two longitudinal adjustment cylinders.

[0008] In the design, the first and second slides of the gripping and transferring component of the adjustment mechanism are slidably mounted on the guide frame via slide rods. The cylinders include a longitudinal adjustment cylinder, a first lateral adjustment cylinder, and a second lateral adjustment cylinder. The two longitudinal adjustment cylinders are also respectively mounted on the first and second slides and connected to the gripping frame. This achieves multi-dimensional support for the movement trajectory of the gripping frame and a reasonable layout of the drive components. It has the advantage of laying a structural foundation for subsequent precise adjustment of the gripping frame position and ensuring that the gripping and transferring component can stably adapt to the gripping needs of different temporary storage mechanisms.

[0009] Preferably, the longitudinal adjusting cylinder is used to drive the gripping frame to move in the vertical direction, and the first lateral adjusting cylinder and the second lateral adjusting cylinder are both mounted on the support frame and are used to drive the second slide and the first slide to slide horizontally along the guide frame direction, respectively.

[0010] In the design, the longitudinal adjustment cylinder is used to drive the gripper to move in the vertical direction, and the first and second lateral adjustment cylinders drive the second slide and the first slide to slide horizontally along the guide frame, respectively. This realizes the independent and coordinated motion adjustment of the gripper in the horizontal and vertical directions, which has the advantage of precisely controlling the position of the pneumatic suction cup to grip and transfer silicon steel sheets, and can effectively reduce the position deviation during the gripping and transfer process.

[0011] Preferably, the auxiliary silicon steel sheet positioning structure on the base plate of the temporary storage mechanism includes a limiting groove and a limiting plate. The limiting groove is opened on the base plate, and the limiting plate is fixedly installed on the base plate. The temporary storage mechanism also includes an insert plate, which is inserted into the limiting groove and is kept perpendicular to the base plate by the limiting plate.

[0012] In the design, the base plate of the temporary storage mechanism is equipped with a limiting groove and a limiting plate. The insert plate is inserted into the limiting groove and kept perpendicular to the base plate by the limiting plate, which realizes the auxiliary positioning and posture regularization of the silicon steel sheet during the temporary storage stage. It has the advantage of further constraining the position of the silicon steel sheet and preventing it from shifting or tilting, thus improving the stability of the pre-positioning of the silicon steel sheet.

[0013] Preferably, the temporary storage mechanism further includes mounting bolts, and the base plate has screw holes. The limiting frame is fixed to the base plate by the mounting bolts cooperating with the screw holes.

[0014] In the design, the limiting frame of the temporary storage mechanism is fixed by mounting bolts and screw holes in the base plate, realizing the detachable and stable installation of the limiting frame on the base plate. It has the advantage of flexibly adjusting the installation state of the limiting frame according to the specifications or quantity of silicon steel sheets, and enhances the adaptability of the temporary storage mechanism to silicon steel sheets of different specifications.

[0015] Preferably, the placement mechanism includes a scissor lift assembly, a placement plate, and a second positioning rod. The placement plate is mounted on the scissor lift assembly, the second positioning rod is vertically mounted on the placement plate, and the bottom of the scissor lift assembly is equipped with casters with brake devices.

[0016] In the design, the placement plate of the placement mechanism is installed on the scissor lift assembly, the second positioning rod is vertically installed on the placement plate, and the bottom of the scissor lift assembly is equipped with casters with brake devices, which realizes flexible adjustment of stacking height, positioning when silicon steel sheets are stacked, and convenient movement and fixation of the placement mechanism.

[0017] Preferably, the silicon steel sheet has positioning holes that cooperate with the first positioning rod of the temporary storage mechanism and the second positioning rod of the placement mechanism.

[0018] In the design, the positioning holes of the silicon steel sheets cooperate with the first positioning rod of the temporary storage mechanism and the second positioning rod of the placement mechanism, respectively, to realize the positioning connection of the silicon steel sheets from temporary storage to stacking. This has the advantage of ensuring that the positioning reference of the silicon steel sheets is consistent in the temporary storage stage and the stacking stage, and further reduces the alignment error when silicon steel sheets of different specifications are stacked alternately.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The adjustment mechanism of this utility model has two temporary storage mechanisms movably installed on the positioning frame. The two temporary storage mechanisms are respectively pre-positioned for two different specifications of silicon steel sheets. The base plate of the temporary storage mechanism is vertically installed with a first positioning rod and a limit frame and is provided with an auxiliary positioning structure.

[0023] 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.

[0024] Example To achieve efficient and precise stacking operations in transformer core processing and solve the alignment problem of alternating stacks of cores of different specifications, such as... Figures 1 to 8 As shown, this utility model provides an embodiment: a stacking device for processing transformer cores, including an adjusting mechanism 1, a temporary storage mechanism 2 installed on the adjusting mechanism 1, and a placement mechanism 3 movable to the inside of the adjusting mechanism 1. The structure and cooperation relationship of each part are as follows: The adjustment mechanism 1, acting as the central coordination hub for the device's transport, is responsible for gripping the iron core components from the temporary storage mechanism 2 and precisely transferring them to the placement mechanism 3. The adjustment mechanism 1 includes a support frame 11, which serves as the basic load-bearing framework for the entire adjustment mechanism, providing installation support for other components. It has two positioning frames 111 on it for limiting the insertion of the two temporary storage mechanisms 2. A positioning reference surface is located on the inner side of the support frame 11 near the placement mechanism 3. Specifically, the two positioning frames 111 are coplanar, facing opposite sidewalls of the placement mechanism 3; this coplanar sidewall is the positioning reference surface. This plane is perpendicular to the length direction of the guide frame 12 and maintains a preset parallel relationship with the edge of the placement plate 32. When the side of the scissor-lift assembly 31 of the placement mechanism 3 is pressed against the opposite sidewall of the two positioning frames 111, the placement mechanism 3 is in a preset working position. The operator only needs to observe whether the scissor-lift assembly 31 is pressed against the sidewall of the positioning frame 111 to determine whether the horizontal position of the placement mechanism 3 is accurate.

[0025] A guide frame 12 is also installed on the support frame 11. The guide frame 12 cooperates with the support frame 11 to provide a guide track for the movement of the first slide 13 and the second slide 18, ensuring the straightness and stability of the movement of each component. The first slide 13 is driven by the second lateral adjustment cylinder 16 and can slide along the guide frame 12 in cooperation with the slide rod 17; the second slide 18 is driven by the first lateral adjustment cylinder 15 and also slides along the guide frame 12 in cooperation with the slide rod 17. A longitudinal adjustment cylinder 14 is installed on the first slide 13 and the second slide 18 respectively. The cylinder body ends of the two longitudinal adjustment cylinders 14 are fixed to the first slide 13 and the second slide 18 respectively, and the gripping frame 19 is fixedly installed on the piston ends respectively.

[0026] The first lateral adjustment cylinder 15, the second lateral adjustment cylinder 16, and the longitudinal adjustment cylinder 14 work together, and the accuracy of the action is ensured by the structural size adaptation: the length direction of the guide frame 12 is perpendicular to the positioning reference plane of the support frame 11. When the scissor lifting component 31 of the placement mechanism 3 is close to the positioning reference plane, the stacking area of ​​the placement plate 32 and the central axis of the guide frame 12 maintain a preset alignment relationship. The maximum stroke of the first lateral adjustment cylinder 15 and the second lateral adjustment cylinder 16 is preset according to the horizontal distance between the temporary storage mechanism 2 and the placement mechanism 3. When the first slide 13 and the second slide 18 are driven to slide along the guide frame 12 to the preset stroke end point, the horizontal position of the gripping frame 19 is exactly aligned with the stacking area of ​​the placement plate 32.

[0027] The stroke of the longitudinal adjustment cylinder 14 is preset according to the initial height of the placement plate 32 and the thickness of the silicon steel sheet 24: During the initial stacking, the scissor lifting component 31 of the placement mechanism 3 adjusts the placement plate 32 to the lowest working height, and the longitudinal adjustment cylinder 14 drives the gripping frame 19 to descend to the preset stroke, so that the silicon steel sheet 24 gripped by the pneumatic suction cup 191 fits exactly against the surface of the placement plate 32; as the stacking height increases, the scissor lifting component 31 synchronously lowers the height of the placement plate 32, and the longitudinal adjustment cylinder 14 always operates according to the preset stroke to ensure that the silicon steel sheet 24 is stably placed on the placement plate 32.

[0028] The gripping frame 19 is equipped with a pneumatic suction cup 191, which can grip the iron core component on the temporary storage mechanism 2. The iron core component is a silicon steel sheet 24.

[0029] The temporary storage mechanism 2 serves as a temporary storage and pre-positioning station for the silicon steel sheets 24, providing a foundation for the precise gripping of the adjustment mechanism 1. The temporary storage mechanism 2 includes a base plate 21, which is the supporting foundation plate for the temporary storage mechanism 2. The base plate 21 has screw holes 211, limiting grooves 212, and limiting plates 213. The screw holes 211 are used to stack and install limiting brackets 25 on the base plate 21 using mounting bolts 26. The number of limiting brackets 25 installed can be determined by stacking them according to the number of silicon steel sheets 24.

[0030] The silicon steel sheet 24 is a core component of the transformer core, and it has a positioning hole 241. A first positioning rod 22 is vertically mounted on the base plate 21. The first positioning rod 22 passes through the positioning hole 241 of the silicon steel sheet 24, and the cross-section of the first positioning rod 22 is smaller than the diameter of the positioning hole 241, thereby initially positioning the silicon steel sheet 24. The limiting groove 212 cooperates with the limiting plate 213 to keep the insert plate 23 perpendicular to the base plate 21 when it is inserted. The insert plate 23 can align and limit the silicon steel sheet 24 inside the limiting frame 25 to prevent the silicon steel sheet 24 from shifting and facilitate the gripping of the adjusting mechanism 1.

[0031] The placement mechanism 3 is the final stacking and forming station for the iron cores, used to receive the iron core components transferred by the adjustment mechanism 1 and complete the stacking. The placement mechanism 3 includes a scissor-lift assembly 31, which serves as the lifting actuator of the placement mechanism and can flexibly adjust the height of the placement plate 32 to adapt to different height requirements during the iron core stacking process. The bottom of the scissor-lift assembly 31 is equipped with casters 311, which facilitates the independent movement and adjustment of the placement mechanism 3. The casters 311 are equipped with brake devices. When the scissor-lift assembly 31 of the placement mechanism 3 is close to the positioning reference surface of the support frame 11, the brake devices fix the casters 311 to ensure the stability of the placement mechanism 3 during the stacking process.

[0032] The placement plate 32 is a flat platform for stacking iron cores, used to receive the iron core components transferred by the adjustment mechanism 1. In conjunction with the scissor-type lifting assembly 31, the placement plate 32 can adjust its height according to changes in stacking height. A second positioning rod 33 is vertically mounted on the placement plate 32. The second positioning rod 33 engages with the positioning hole 241 of the silicon steel sheet 24 to perform final stacking positioning of the transferred iron core components: when the gripping frame 19 of the adjustment mechanism 1 moves the silicon steel sheet 24 above the placement plate 32, the positioning hole 241 of the silicon steel sheet 24 precisely fits into the second positioning rod 33, completing the placement of the silicon steel sheet 24 on the placement plate 32. This ensures accurate alignment when iron core components of different specifications are stacked alternately, guaranteeing the quality of iron core stacking.

[0033] When using this utility model, the two temporary storage mechanisms 2 are mounted on the support frame 11 via the positioning frame 111 of the adjustment mechanism 1, the placement mechanism 3 is pushed to make the scissor lifting assembly 31 stick to the opposite side wall of the positioning frame 111, and the caster 311 is stepped on to brake and fix it.

[0034] The limiting frame 25 is fixed by the mounting bolt 26 through the screw hole 211 of the base plate 21, and the insert plate 23 is inserted into the limiting groove 212 and kept vertical by the limiting plate 213.

[0035] Two types of silicon steel sheets 24 are placed into the temporary storage mechanism 2, and the first positioning rod 22 passes through the positioning hole 241 and is pressed against the insert plate 23 and the limit frame 25 to complete the pre-positioning.

[0036] The first lateral adjustment cylinder 15 and the second lateral adjustment cylinder 16 drive the second slide 18 and the first slide 13 to move along the slide rod 17 of the guide frame 12, and the gripping frame 19 moves above the silicon steel sheet 24; the longitudinal adjustment cylinder 14 lowers the gripping frame 19, and the pneumatic suction cup 191 rises after it is gripped tightly.

[0037] The first lateral adjustment cylinder 15 and the second lateral adjustment cylinder 16 move the silicon steel sheet 24 above the placement plate 32, the longitudinal adjustment cylinder 14 descends, causing the second positioning rod 33 to pass through the positioning hole 241, and the pneumatic suction cup 191 releases the silicon steel sheet 24.

[0038] As the stack gradually increases in height, the scissor lift assembly 31 lowers the placement plate 32, alternating operations until completion, and finally the brake is released to remove the placement mechanism 3.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
