[0049] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] In this embodiment, Figure 1 As shown, the magnetic steel assembly that needs to be bonded includes an iron yoke 800 and magnets bonded to the upper surface of the iron yoke 800 and arranged in M ​​rows and N columns, where M is 3 and N is 2. The three magnets in each column are, in order from back to front, a first magnet 910, a second magnet 920 and a third magnet 930. Each magnet is in the shape of a rectangular parallelepiped and has the same thickness. The size of the magnets in the same column along the left-right direction, i.e., the length, is consistent, and the size of the magnets in the same row along the front-to-back direction, i.e., the width, is consistent.

[0052] This embodiment provides a horizontal motor magnetic steel assembly bonding tool, such as Figures 2 to 6 As shown, the bonding tool includes a base 100, a first fixing member 510, (N-1=2-1=1) placeholders 200, (M×N=3×2=6) push plates, (M×N=3×2=6) first pressing members 410 and M=3 second pressing members 420; the base 100 is provided with a receiving cavity, after the magnet is bonded to the iron yoke 800 in the receiving cavity, the distance between the upper surface of the magnet and the upper wall of the receiving cavity is less than the length of the diagonal m and n of the vertical surface of the magnet; the first fixing member 510 is used to fix the iron yoke 800 in the receiving cavity; along the left and right directions, the size of the placeholder 200, i.e., the length, is the size of the N=2nd column of magnets, i.e., the length; along the front In the rear direction, the size, i.e., the width, of the placeholder 200 is the same as the size, i.e., the width, of the magnetic matrix; the thickness of the placeholder 200 is less than or equal to the distance between the iron yoke 800 and the upper wall of the accommodating cavity after the iron yoke 800 is bonded; the push plate corresponds one-to-one to the magnet, and the push plate can push the corresponding magnet backward to the specified position; the first clamping member 410 corresponds one-to-one to the magnet, and the first clamping member 410 can be fixed respectively to the top wall of the base 100, and are respectively used to press the corresponding bonded magnet downward; each second clamping member 420 corresponds respectively to a row of magnets, and the second clamping member 420 can be fixed respectively to the right side wall of the base 100, and are respectively used to press the corresponding bonded magnet to the left.

[0053] The horizontal motor magnet assembly bonding fixture provided in this embodiment can bond the magnets of the magnet matrix to the iron yoke 800 column by column. Taking bonding from left to right column by column as an example, when using the bonding fixture provided in this embodiment, first use the first fixing member 510 to fix the iron yoke 800 in the accommodating cavity of the base 100, and place the placeholder 200 at the corresponding position on the upper surface of the iron yoke 800 in the accommodating cavity; then, after applying glue on the surface of the magnet that contacts the iron yoke 800 and the adjacent magnet, place the magnet on the upper surface of the iron yoke 800, and use the push plate corresponding to the magnet to push the magnet to the finger Then, fix the push plate, use the corresponding second pressing piece 420 to press the bonded magnet to the left, and use the corresponding first pressing piece 410 to press the bonded magnet downward to complete the three-way positioning of the bonded magnet; after bonding one magnet, loosen the fixed second pressing piece 420, withdraw the push plate, replace the next push plate, push the next magnet coated with glue to its designated position and press it, and so on, until all the magnets in the first column are bonded; after bonding one column of magnets, loosen all the second pressing pieces 420, and then bond the second column of magnets.

[0054] The horizontal motor magnet assembly bonding fixture provided in this embodiment is capable of bonding a magnet assembly having a magnet matrix with M rows and N columns, and the setting of the placeholder 200 effectively limits the rotation of the magnet in the vertical direction. After the magnet is bonded to the iron yoke 800 in the accommodating cavity, the distance between the upper surface of the magnet and the upper wall of the accommodating cavity is less than the length of the diagonals m and n of the vertical surface of the magnet, so the bonding fixture can limit the flipping of the magnet in the horizontal direction, that is, the bonding fixture can effectively limit the rotation of the magnet during the bonding process, which is beneficial to reducing the scrap rate of the magnet and improving the product qualification rate of the magnet assembly.

[0055] It should be noted that in other embodiments of the present application, the number of placeholders 200 may still be (N-1), but each placeholder 200 may correspond to a column of magnets respectively, and along the left and right directions, the size of each placeholder 200 is consistent with the size of the magnets in the corresponding column. When the magnets are bonded column by column, the placeholders 200 are taken out one by one; or, the number of placeholders 200 may also be M×(N-1), which are used to occupy M×(N-1) magnets in the unbonded columns respectively. When bonding to a certain column, all the placeholders 200 in the column can be taken out.

[0056] It should be noted that in other embodiments of the present application, a push plate can also be used to push the corresponding magnetic steel forward to a specified position.

[0057] It should be noted that in other embodiments of the present application, the second clamping members 420 can also be fixed to the left side wall of the base 100 respectively. When the magnets are bonded row by row from right to left, each second clamping member 420 is used to press the corresponding bonded magnet to the right.

[0058] It should also be noted that, in other embodiments of the present application, the number of first pressing members 410 may not be limited to (M×N), but it is necessary to ensure that one magnet is pressed downward by at least one first pressing member 410, that is, one magnet can be pressed downward by two or even more first pressing members 410; the number of second pressing members 420 may also not be limited to M, but it is necessary to ensure that the same row of magnets is laterally pressed by at least one second pressing member 420, that is, one row of magnets can be laterally pressed by two or even more second pressing members 420.

[0059] Specifically, in this embodiment, Figure 4As shown, the push plates include two first push plates 310, two second push plates (not shown in the figure), and two third push plates 330. The two first push plates 310 are respectively used to push the two first magnetic steels 910, the two second push plates are respectively used to push the two second magnetic steels 920, and the two third push plates 330 are respectively used to push the two third magnetic steels 930. Of course, in this embodiment, since the magnetic steel matrix only includes three rows and two columns of magnetic steel, the number of first push plates 310 and second push plates can also be only one. When bonding the first column of magnetic steel, the first push plates 310, the second push plates, and the third push plates 330 are used in sequence. After the bonding of the first column of magnetic steel is completed, only one third push plate is required to fix the first column of magnetic steel. The second push plates and the third push plates 330 can be used together with another third push plate to continue bonding the second column of magnetic steel.

[0060] Specifically, in this embodiment, after the magnet assembly is bonded, the distance y between the upper surface of the magnet and the upper wall of the cavity is in the range of 1-2 mm. With this arrangement, the value of y is small, and the upper wall of the cavity effectively restricts the magnet, making it easier to place the magnet into the cavity and push the magnet to a designated position using the push plate.

[0061] Specifically, in this embodiment, Figures 3 to 5 As shown, the base 100 includes a fixed base 110, a shaping base 120 and an upper cover 130. The upper cover 130 is fixedly connected to the fixed base 110 and the two form a front-to-back through-accommodation groove; the shaping base 120 is arranged on the fixed base 110 and is partially or completely located in the accommodation groove; the left inner wall surface of the fixed base 110, the bottom surface of the upper cover 130, the right inner wall surface of the fixed base 110, the upper surface of the shaping base 120 opposite to the bottom surface of the upper cover 130, and the vertical inner wall surface of the shaping base 120 form an accommodation cavity.

[0062] More specifically, in this embodiment, Figure 3 and Figure 4 As shown, the upper cover 130 and the fixed base 110 are split structures, and the two are detachably fixedly connected. When bonding the iron yoke 800, the upper cover 130 can be removed, thereby conveniently placing the iron yoke 800 on the shaping base 120; after the magnetic steel assembly is bonded and cured, the upper cover 130 can be removed, thereby conveniently removing the bonded and cured magnetic steel assembly. However, it should be noted that in other embodiments of the present application, the upper cover 130 and the fixed base 110 can also be an integrated structure.

[0063] Specifically, in this embodiment, the shaping base 120 is slidably disposed on the fixed base 110 in the front-to-back direction. In this arrangement, the iron yoke 800 can be first placed on the shaping base 120 and then pushed into the receiving groove via the shaping base 120. After the magnetic steel assembly is bonded and cured, the magnetic steel assembly can be pulled out of the receiving groove via the shaping base 120 and then removed from the shaping base 120, greatly improving bonding efficiency.

[0064] Specifically, in this embodiment, Figure 3 As shown, the bottom of the upper cover 130 is provided with at least N slots 131, and the slots 131 pass through the upper cover 130 in the front-to-back direction; the bonding tool also includes a pressure rod, which can be inserted into the slot 131 and press the bonded magnetic steel assembly to the forming base 120. In this setting form, after bonding a magnetic steel assembly, the pressure rod can be inserted into the slot 131 and fixed to the forming base 120, so that the pressure rod presses the corresponding column of magnetic steel to the iron yoke 800, and then the forming base 120, the pressure rod and the compressed magnetic steel assembly are pulled out of the receiving groove as a whole for curing. At the same time, the fixed base 110 and the upper cover 130 can be used for the bonding of another magnetic steel assembly, that is, the parts of the bonding tool can be used in combination to complete the bonding and curing of multiple magnetic steel assemblies using a total number of parts that is less than the total number of parts of multiple sets of tooling, thereby reducing the cost of the bonding tool.

[0065] Specifically, in this embodiment, Figure 3 and Figure 4 As shown, the bonding tool also includes N = 2 fixing plates 610, each corresponding to a row of magnets and push plates. The fixing plates 610 can be fixed to the shaping base 120 and used to compress the corresponding row of push plates and bonded magnets. After bonding a particular magnet, the fixing plate 610 is fixed to the shaping base 120 and abuts against the push plate corresponding to the magnet, thereby restricting the forward movement of the push plate and magnet, thereby completing the front-to-back positioning of the magnet.

[0066] Specifically, in this embodiment, continue as Figure 3 and Figure 4 As shown, the fixing plate 610 is provided with a waist-shaped groove, the length of which extends in the vertical direction. The fastener passes through the waist-shaped groove to secure the fixing plate 610 to the fixed base 120. In this arrangement, when it is necessary to restrict the forward movement of the push plate and the magnet, the fixing plate 610 is fastened to the fixed base 120; when it is necessary to replace the push plate, the fastener is loosened to allow the fixing plate 610 to fall, without having to remove the fixing plate 610, saving time. In addition, the fixing plate 610 is hung on the fastener, which can effectively prevent it from being lost.

[0067] Specifically, in this embodiment, the upper surface portion of the shaping base 120 for mounting the iron yoke 800 matches the bottom surface of the iron yoke 800. This arrangement facilitates accurate and rapid mounting of the iron yoke 800 on the shaping base 120.

[0068] More specifically, in this embodiment, the bottom surface of the iron yoke 800 is V-shaped when viewed from the left or right side of the iron yoke 800 . Accordingly, the upper surface of the shaping base 120 is provided with a V-shaped groove matching the bottom surface of the iron yoke 800 .

[0069] Specifically, in this embodiment, Figure 6 As shown, the rear surface of the push plate is provided with a first protrusion 311, which is used to abut the magnetic steel corresponding to the push plate; the front surface of the push plate is provided with a second protrusion 312, which is used to abut the fixed plate 610 corresponding to the push plate. The provision of the first protrusion 311 reduces the contact area between the push plate and the magnetic steel, thereby alleviating the uneven force applied to the magnetic steel when the push plate and the magnetic steel contact a large area; the provision of the second protrusion 312 reduces the contact area between the push plate and the fixed plate 610, thereby alleviating the uneven force applied to the push plate when the push plate and the fixed plate 610 contact a large area.

[0070] Preferably, in this embodiment, continue as Figure 6 As shown, there are two first protrusions 311, which are spaced apart at the left and right ends of the rear surface of the push plate; there are also two second protrusions 312, which are spaced apart at the left and right ends of the front surface of the push plate.

[0071] This embodiment further provides a method for bonding a horizontal motor magnetic steel assembly. The method uses the aforementioned bonding tool to bond the iron yoke 800 and to bond the magnetic steel matrix column by column, and includes the following steps:

[0072] Use the first fixing member 510 to fix the iron yoke 800 to the receiving cavity of the base 100;

[0073] Place the required placeholder 200 at the corresponding position on the upper surface of the iron yoke 800;

[0074] Apply glue to the surface of the magnet that contacts the iron yoke 800 and the adjacent magnets, place the glue-coated magnet on the upper surface of the iron yoke 800, and use the push plate corresponding to the magnet to push the magnet to the designated position;

[0075] Fix the push plate, use the corresponding second pressing member 420 to press the bonded magnetic steel to the left or right, and use the corresponding first pressing member 410 to press the bonded magnetic steel downward;

[0076] Loosen the fixed second pressing member 420, withdraw the push plate, replace the next push plate, push the next magnet coated with glue to its designated position and press it, and so on, until all the magnets in the first column are bonded;

[0077] All the second pressing members 420 are released, and the next placeholder 200 is replaced. The second row of magnets is bonded, and so on, until all the magnets are bonded.

[0078] The horizontal motor magnet assembly bonding method provided in this embodiment can bond a magnet assembly having a magnet matrix with M rows and N columns, and uses placeholders 200 to fill the vacancies of unbonded magnets, which can effectively limit the rotation of the magnets in the vertical direction. After the magnets are bonded to the iron yoke 800 in the accommodating cavity, since the distance between the upper wall of the bonding tool accommodating cavity and the upper surface of the magnet is less than the length of the diagonals m and n of the vertical surface of the magnet, the flipping of the magnet in the horizontal direction can be restricted. That is, the use of this bonding method can effectively limit the rotation of the magnets during the bonding process, which is beneficial to reducing the scrap rate of the magnets and improving the qualified rate of the products.
