Description

Technical Field

[0001] This utility model relates to the field of sine and cosine angle sensor technology, specifically to a stator stacking device and method that can control and buffer pressure, and more particularly to a stator bonding and stacking device. Background Technology

[0002] Due to its high permeability and low coercivity, the iron-nickel soft magnetic alloy 1J50 is often used as the stator and rotor material for aerospace sensors. For single / double redundancy sine and cosine sensors, the stator involves processes such as stamping, heat treatment, cleaning, bonding, stacking, turning the inner and outer circles, and winding before being assembled into the sensor.

[0003] Currently, the stator bonding process for most similar products generally involves applying adhesive to each stator lamination individually, applying a locking force after all stator laminations are bonded, and finally curing at high temperature. This method ignores the uniformity of pressure between each stator lamination. The stress on each stator lamination is not equal to the final pressure applied during bonding; that is, the degree of compression experienced by the first, middle, and last stator laminations differs. This is because this method makes it difficult to precisely control the stress during bonding of each stator lamination and does not consider the degree of adhesive curing between the first bonded laminations, uneven adhesive application, and the slight deformation and uneven stress on the stator laminations caused by adhesive curing. Furthermore, uneven stress between the stator laminations during bonding can easily lead to stator cracking during subsequent machining processes. After bonding each stator lamination, a large bonding force is often applied and locked to ensure bonding strength, but excessive bonding force often results in a significant reduction in the final stator magnetic performance. 1J50 is a stress-sensitive soft magnetic material. Uneven stress during the bonding and lamination process will directly affect the quality of the final stator's magnetic properties. Stator magnetic properties produced in batches using this bonding and lamination method fluctuate greatly, and the magnetic property loss after stator lamination can even exceed 90%.

[0004] In typical stator bonding and lamination processes, limiting measures are used during stator lamination to ensure dimensional consistency. However, this method ignores the impact of uneven stator lamination thickness. Different batches of stator laminations may have thicknesses exceeding the standard tolerance. Due to cumulative errors, the final stator thickness varies, while the height remains consistent. Therefore, for stators with thicknesses exceeding the standard, the lamination pressure is relatively high, increasing stress; conversely, for stators with thicknesses below the standard, the lamination pressure is relatively low, weakening the bond strength. This new device applies equal lamination pressure to each stator lamination, eliminating the need to consider the cumulative dimensional errors of the stator laminations on the bonding effect.

[0021] A stator bonding and lamination method, which uses a stator bonding and lamination device to laminate stator laminations, includes the following specific steps:

[0022] 1) A stator bonding and stacking device is placed on the worktable of a press. The lower pressing part of the press is connected to the stacking column, and the membrane pressure tester is connected to the press control system. During the stacking loading, the feedback signal of the membrane pressure tester is automatically collected, and the pressure of the press is precisely controlled.

[0023] Then set the press preload to 2N, displacement to 0.1mm, and holding time to 15s;

[0024] 2) Adjust the positioning device to ensure that the pressure plate, positioning device, and stator placement seat are properly matched;

[0025] 3) Apply glue to the first stator lamination, with the glued side facing up, place it into the stator placement seat, and use the positioning device to achieve positioning;

[0026] 4) Place the second stator lamination into the stator mounting base, making it contact the adhesive-coated surface of the first stator lamination, and zero the pressure testing device;

[0027] 5) Start the press, adjust the press until the stacking column contacts the stator laminations, and observe that the pressure test device reading is 0, and the press displacement is zeroed;

[0028] 6) The press begins loading and the pressure testing device values ​​are monitored;

[0029] If the pressure test device reading is less than 10N when the displacement reaches 0.1mm, the displacement will continue to increase. When the pressure test device returns 10N, the displacement will stop and the press will automatically unload after holding the pressure for 15 seconds.

[0030] If the displacement is less than 0.1mm and the pressure test device has already reported a value of 10N, then the loading will stop and the press will automatically unload after holding the pressure for 15 seconds.

[0031] 7) Apply adhesive to one side of the third stator lamination, with the adhesive side facing down, and place it into the stator mounting base; zero the pressure testing device; repeat steps 5-6;

[0034] Tighten the mounting screws on the top cover for connecting the stator mounting base in a small amount, multiple times, and symmetrically, and monitor the pressure testing device. Stop tightening when the pressure feedback from the pressure testing device meets the specified pressure range.

[0035] 9) After the stator bonding and stacking is completed, remove it from the stator placement seat and perform high-temperature curing.

[0036] This utility model has the following beneficial effects:

[0037] This invention utilizes a pressure testing device to precisely control the pressure during the bonding and stacking of each stator lamination, compensating for and eliminating the impact of uneven stator lamination thickness on bonding. It is also easy to operate, and each stator lamination is subjected to uniform and equal force.

[0038] The stator placement base of this invention is equipped with a thin-film pressure tester at the bottom, and the pressure is fed back through the thin-film pressure tester. In this way, the pressure applied to each stator lamination is precisely controlled, avoiding the instability of stator magnetic performance caused by unequal forces between stator laminations.

[0039] This invention improves the quality of the stator by controlling and buffering pressure bonding and stacking, and significantly reduces stator cracking during the turning process. Tests show that the magnetic performance loss of the stator is stable within 10%.

[0040] This invention sets a uniform holding time for each stator lamination after bonding, which ensures the bonding strength of the stator, as well as the consistency of the bonding process and the stability of quality. When using this invention to bond and stack stators, a lower stacking pressure is sufficient to ensure the bonding strength and quality of the stator, avoiding the rapid loss of magnetic properties caused by excessive stacking stress, and ensuring the high magnetic performance level of the stator.

[0041] The support column of this utility model is equipped with a reset spring to buffer the stacking pressure, ensuring that the stacking pressure on each stator lamination is applied slowly, evenly and equally. This method can greatly reduce the adverse effects of stress on the soft magnetic material, such as lattice distortion, dislocation, magnetic domain deformation or destruction, and obstruction of domain wall movement, and avoid irreversible damage to the magnetic domain structure of the material by the stacking pressure impulse.

[0042] This utility model is equipped with a stacking pressure adjustment and compensation measure: when the stacking pressure is not sufficient but the displacement is sufficient, pressure compensation is started until the pressure meets the requirements, and then the pressure is maintained before unloading and the stacking column is reset; when the stacking pressure is sufficient but the displacement is insufficient, the displacement is stopped, the pressure is maintained before unloading and the stacking column is reset.

[0043] This invention applies equal stacking pressure to each stator lamination, eliminating the need to consider the impact of cumulative stator lamination size errors on the bonding effect.

[0044] The positioning plate and adhesive placement seat of this utility model are flexible and adjustable, ensuring the neatness of the stator plate bonding.

[0045] This invention fully considers the stress-sensitive characteristics of 1J50 material. By using stacked pressure buffering and precise control, it can avoid irreversible deformation of the internal structure of the material caused by pressure impulse, and also prevent adverse effects caused by improper control of applied pressure.

[0046] The entire stacking and loading process of this invention is completed according to the set loading curve, which ensures the consistency of the stress state and process of each stator lamination to the greatest extent and avoids the errors caused by manual stacking.

[0047] The thin film pressure tester and press control system of this utility model are equipped with system cross-linking. During the stacking loading, the feedback signal of the pressure tester is automatically collected, which realizes precise pressure control, avoids human operation errors, improves the quality of the finished stator, and ensures the simplicity and controllability of the bonding and stacking process.

[0048] Both the stator placement seat and the adhesive positioning seat of this utility model can be quickly assembled and disassembled. The entire device has no complicated or special connection methods or complicated parts. This device is easy to standardize and is simple to maintain and replace.

[0049] This invention allows for the bonding and stacking of stators of different specifications by simply replacing the stator placement seat and the bonding positioning seat, making the device highly versatile.

[0050] This invention is small in size, light in weight, easy to operate, and produces reliable and consistent stacked stators.

[0051] The stator of this invention, which is bonded and stacked, does not have the situation where the first stator lamination, the middle stator lamination, and the last stator lamination are subjected to different degrees of compression. This stator stacking device can ensure that the stress state of each stator lamination is equal. Attached Figure Description
