[0001] The utility model specifically relates to an auxiliary turnover device for iron core cakes and an iron core cake production line. Background Technique

[0002] A reactor is a core device in a transmission line, and its operation reliability and safety are particularly important. In the traditional turnover process of iron core cakes of reactors, for large and heavy iron core cakes, lifting equipment such as cranes or hoists may be needed to carry out the turnover. These devices require the operator to have sufficient experience to safely lift the iron core cake and move it to the required position; for small iron core cake products, a turnover frame or platform can be used to support the iron core cake and provide a stable working surface. At the same time, in order to ensure the stability of the iron core cake during the turnover process, a matching fixture or fixing device needs to be used to firmly fix the iron core cake.

[0003] These cumbersome steps and a variety of tooling tools make the iron core cake turnover step have a high requirement for the operator's proficiency, and it is very easy to cause damage to the iron core cake during the turnover process. Seriously, it may even cause safety accidents such as personal injuries, thus affecting the overall product quality and production efficiency, and bringing greater safety risks to the operators.

The turnover mechanism includes a bracket, a driving member, and an electro-permanent magnetic chuck for adsorbing the iron core cake by magnetic force. The electro-permanent magnetic chuck is rotatably connected to the bracket. The rotation stroke of the electro-permanent magnetic chuck includes a receiving position for receiving the iron core cake and a placing position for releasing the iron core cake. The placing position is located above the bearing mechanism. The driving end of the driving member drives the electro-permanent magnetic chuck to rotate between the receiving position and the placing position, so that the electro-permanent magnetic chuck turns the received iron core cake and places it on the bearing mechanism.

The electro-permanent magnetic chuck is connected to the rotating shaft, and the driving end of the driving member is connected to the rotating shaft to drive the electro-permanent magnetic chuck to rotate by driving the rotation of the rotating shaft.

[0008] Further, the loading mechanism includes a scissor lift. The top platform of the scissor lift serves as the loading table. After the scissor lift rises, the loading table contacts the core cake that has been flipped to the placement position to carry the core cake.

[0009] Further, the device further includes a central control module. A proximity switch is provided on the upper surface of the loading table.

[0023] Embodiment 1

[0024] As Figure 1 and Figure 2 shown, the auxiliary core cake flipping device of this embodiment includes a flipping mechanism 1 and a carrying mechanism 2. The flipping mechanism 1 includes a bracket 11, a driving member 12, and an electro-permanent magnetic chuck 13 for magnetically adsorbing the core cake 3. The electro-permanent magnetic chuck 13 is rotatably connected to the bracket 11. The rotation stroke of the electro-permanent magnetic chuck 13 includes a receiving position for receiving the core cake 3 and a placing position for releasing the core cake 3. The placing position is located above the carrying mechanism 2. The driving end of the driving member 12 drives the electro-permanent magnetic chuck 13 to rotate between the receiving position and the placing position, so that the electro-permanent magnetic chuck 13 flips the received core cake 3 and then lands on the carrying mechanism 2.

[0025] For the auxiliary core cake flipping device of this embodiment, its flipping mechanism 1 uses an electro-permanent magnetic chuck 13. Utilizing the ferromagnetic property of the silicon steel material of the core cake 3, the core cake 3 is fixed by magnetic adsorption. Then, the driving member 12 drives the electro-permanent magnetic chuck 13 to rotate to flip the core cake 3, and then the core cake 3 lands on the carrying mechanism 2. Compared with the additional fixing devices such as conventional jigs, this flipping and fixing method can first avoid cumbersome operation steps and improve production efficiency. Secondly, it has lower requirements for the proficiency and experience of operators, and the magnetic adsorption is stable and reliable. It can also avoid dangerous accidents caused by operation mistakes and fixture failures. More importantly, the method of adsorbing, fixing, and flipping by the electro-permanent magnetic chuck 13 will not cause mechanical damage to the surface of the core cake 3 and avoid affecting the product quality.

[0026] In this embodiment, the adsorption disk surface of the electro-permanent magnetic chuck 13 at the receiving position faces horizontally upward, and the adsorption disk surface of the electro-permanent magnetic chuck 13 at the placing position faces horizontally downward. During the flipping process, first, the electro-permanent magnetic chuck 13 rotates to the receiving position, with the adsorption disk surface facing horizontally upward, and receives the iron core cake 3 from the previous process. The side of the iron core cake 3 with the ceramic layer faces horizontally upward, and the other side fits against the adsorption disk surface. Then, the driving member 12 drives the electro-permanent magnetic chuck 13 to rotate to the placing position, with the adsorption disk surface facing horizontally downward. Therefore, the iron core cake 3 is flipped accordingly, so that the side with the ceramic layer faces horizontally downward and can be placed on the bearing mechanism 2, completing the flipping from the previous process to the bearing mechanism 2 for subsequent installation and other processing procedures. The driving member 12 can adopt a reduction motor.

[0027] In this embodiment, the bracket 11 includes a rotating shaft 111 and support legs 112. There are two support legs 112, which are respectively installed on both sides of the bearing mechanism 2. The two ends of the rotating shaft 111 are respectively rotatably connected to the tops of the two support legs 112, so that the whole bracket 11 straddles above the bearing mechanism 2. The electro-permanent magnetic chuck 13 is connected to the rotating shaft 111, and the driving end of the driving member 12 is connected to the rotating shaft 111 to drive the electro-permanent magnetic chuck 13 to rotate by driving the rotation of the rotating shaft 111. This bracket 11 with a straddle structure can not only ensure the stable rotation of the electro-permanent magnetic chuck 13, but also does not interfere with the rotation stroke of the electro-permanent magnetic chuck 13, and can also ensure the activity space of the lower bearing mechanism 2.

[0028] In this embodiment, the bearing mechanism 2 includes a scissor lift 21. The top platform of the scissor lift 21 serves as the bearing platform 22. After the scissor lift 21 rises, the bearing platform 22 contacts the iron core cake 3 flipped to the placing position to bear the iron core cake 3. Through lifting, it can be ensured that the bearing platform 22 contacts the iron core cake 3 to prevent it from falling from a height and causing surface damage or serious dangerous accidents. The scissor lift 21 is a relatively conventional lifting mechanism on the market at present, including a scissor-shaped hinged structure connected between the top platform and the bottom platform. By pushing the scissor-shaped hinged structure to move around the hinge point, the lifting of the top platform is realized. Specifically, a motor, a hydraulic cylinder, a cylinder, etc. can be used for driving inside. Since it is a conventional structure, no specific description is made here.

[0029] In this embodiment, the device further includes a central control module. A proximity switch is provided on the upper surface of the bearing platform 22. The proximity switch is electrically connected to the central control module. After the bearing platform 22 contacts the iron core cake 3, it is triggered and sends a first signal to the central control module. The central control module is electrically connected to the electro-permanent magnetic chuck 13 and controls the electro-permanent magnetic chuck 13 to demagnetize and release the iron core cake 3 according to the first signal. By setting the proximity switch and the central control module, the electro-permanent magnetic chuck 13 can automatically release the iron core cake 3 after the bearing platform 22 contacts the iron core cake 3, ensuring product safety, improving the automation level of the device, further simplifying the operation steps of the operator, and avoiding human errors.

[0030] In this embodiment, a position sensor for sensing whether the electro-permanent magnetic chuck 13 reaches the placement position is provided on the electro-permanent magnetic chuck 13. The position sensor can be an angular displacement sensor or a conventional position sensor, and is based on being able to sense the relative position between the electro-permanent magnetic chuck 13 and the placement position. It can be set on the electro-permanent magnetic chuck 13 or on the rotating shaft 111. The position sensor is electrically connected to the central control module, and is triggered after the electro-permanent magnetic chuck 13 reaches the placement position and sends a second signal to the central control module. The central control module is electrically connected to the scissor lift 21, controls the scissor lift 21 to rise according to the second signal, and controls the scissor lift 21 to descend according to the first signal. That is, the overall flipping and receiving process is as follows: after the flipping is completed, the scissor lift 21 raises the carrying platform 22. After contacting the core cake 3, the electro-permanent magnetic chuck 13 demagnetizes, and the core cake 3 falls on the carrying platform 22. After the core cake 3 is placed stably, the scissor lift 21 descends, and the whole process can be completely automated.

[0031] In this embodiment, for the position sensor, proximity switch, etc., conventional sensing components on the market that can play the corresponding sensing role (all are mature component products) can be selected. The connection between each component and the central control module can be selected as a wired connection or a wireless connection method. The connection method and the setting position of the central control module can be conventionally selected according to the specific structure and layout of the device. The signal reception of the central control module and the control functions for the scissor lift 21 and the electro-permanent magnetic chuck 13 are all conventional signal transceiver and control functions, so a conventional control device on the market (such as a PLC) can be used to complete them, and thus no specific details will be described here.

[0032] The electro-permanent magnetic chuck 13 is a relatively mature technology at present. The electro-permanent magnetic chuck 13 adopted in this embodiment can achieve magnetization and demagnetization by supplying positive or reverse power to the coil of the electro-permanent magnetic chuck 13. For example, supplying positive power to the coil of the electro-permanent magnetic chuck 13 makes the magnetic force of the electromagnet and the permanent magnet superimpose to increase the adsorption force, and supplying reverse power to the coil of the electro-permanent magnetic chuck 13 makes the magnetic force of the electromagnet and the permanent magnet cancel each other to achieve demagnetization. This method can also ensure that the chuck has adsorption force in the event of an emergency power failure, avoiding the sudden dropping of the core cake 3. As an electro-permanent magnetic adsorption fixture, the electro-permanent magnetic chuck 13 selected in this embodiment has a rated adsorption load that can reach 600 kg.

[0033] In this embodiment, a protective pad 25 is padded on the upper surface of the carrying platform 22 for protecting the surface structure of the core cake 3. The protective pad 25 can specifically be a polyurethane pad. Holes can be opened on the protective pad 25 to set a proximity switch, and the setting position of the proximity switch is based on being able to sense the contact with the core cake 3.

[0034] In this embodiment, a relief groove for avoiding subsequent process jigs is formed in the protective pad 25, which facilitates the operation of the subsequent process jigs on the iron core cake 3. The structural dimensions of the relief groove can be appropriately changed according to different processes and will not be elaborated herein.

[0035] In this embodiment, the carrying mechanism 2 further includes a slide table 23 and a guide rail 24. The guide rail 24 is arranged between the carrying position below the placing position and the avoiding position avoiding the placing position below. Specifically, the carrying position is directly below the placing position, and the avoiding position is on one side below the placing position and is not in the same vertical direction as the placing position. The slide table 23 is slidably arranged on the guide rail 24, and the scissor lift 21 is installed on the slide table 23 and can move between the carrying position and the avoiding position under the support of the slide table 23. In this embodiment, a cylinder can be used to drive the slide table 23 to slide on the guide rail 24, and the effective stroke is 1000 mm. The carrying mechanism 2 can not only move to the carrying position to receive the iron core cake 3, but also move to the avoiding position to avoid the flipping mechanism 1, so as to avoid affecting the subsequent process operations.

[0036] Generally speaking, this embodiment can be used in the technical field of reactor manufacturing. Specifically, it provides an automatic device for assisting the flipping of the iron core cake with simple and reliable operation and convenient use. It can be summarized as an electro-permanent magnetic flipping machine. The iron core cake is firmly held by the electro-permanent magnetic chuck fixture on the rotating shaft 111, and the motor drives the rotating shaft 111 to drive the iron core cake to complete the flipping.

Its installation position, layout, etc. can be conventionally selected according to needs and will not be elaborated herein. Lifting devices are arranged on both the front and rear sides of the iron core cake auxiliary flipping device, and the lifting devices can adopt structures such as robotic arms. The iron core cake auxiliary flipping device is used to flip the iron core cake, as shown in Embodiment 1. The lifting devices on both sides are respectively used to place the iron core cake on the electro-permanent magnetic chuck 13 of the iron core cake auxiliary flipping device and take away the iron core cake that has been flipped on the carrying mechanism 2.
