Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example

[0040] A production line for processing blocks into ferrite magnetic discs, the production line comprising:

[0041] Square mold: The interior of the square mold is used to place magnetic powder;

[0042] Press: The press is used to press the magnetic powder in the square mold into a square green body;

[0043] Bell furnace: The bell furnace is placed at the tail of the press and is used to sinter the green block to transform the green block into a rough block;

[0044] The first magnetic material wire cutting machine: the first magnetic material wire cutting machine is placed at the tail of the bell furnace, and the first magnetic material wire cutting machine is used to cut the square blank into a plurality of square strip blanks;

[0045] Rounding machine: The rounding machine is placed at the tail of the first magnetic material wire cutting machine, and is used to perform rough processing on the square bar blank so that the square bar blank is processed into a cylindrical blank;

[0046] Centerless external circular grinding machine: The centerless external circular grinding machine is placed at the tail of the first magnetic material wire cutting machine, and is used for finishing the cylindrical blank so that the cylindrical blank is processed into a cylindrical part;

[0047] Bonding platform: The bonding platform is placed at the tail of the centerless external grinding machine, and a plurality of cylindrical rectangular arrays are placed in the bonding platform. The bonding platform is used to bond the cylindrical members arranged in the rectangular array into one;

[0048] The second magnetic material wire cutting machine: the second magnetic material wire cutting machine is placed at the tail of the bonding platform, and the second magnetic material wire cutting machine is used to cut the cylindrical part bonded as one into a plurality of round pieces bonded as one;

[0049] Immersion separation tank: The immersion separation tank is placed at the tail of the second magnetic material wire cutting machine, and the wafers bonded together are immersed in the immersion separation tank. The immersion separation tank is used to decompose the wafers bonded together into individual wafers.

[0050] like Figure 2 and Figure 3 As shown, the bonding platform 1 includes an outer cover 1, a first positioning member 2, a second positioning member 3, and a third positioning member 4. The top and one side of the outer cover 1 are open structures. The first positioning member 2 and the second positioning member 3 are symmetrically installed on both sides of the outer cover 1. The first positioning member 2 and the second positioning member 3 clamp and position the cylindrical members arranged in a rectangular array from both sides. The third positioning member 4 is inserted into the opening of the outer cover 1. The third positioning member 4 is used to clamp and position the cylindrical members arranged in a rectangular array;

[0051] The cylindrical members are arranged vertically in the outer cover body 1, and the cavities between the four cylindrical members are filling gaps, in which adhesive is filled; the cylindrical members can be clamped and positioned from the left and right sides by the first positioning member and the second positioning member to achieve left and right side positioning; the detachable third positioning member can be removed during loading, and inserted during processing to achieve outer side clamping and positioning, thereby achieving four-sided positioning, ensuring that the vertically distributed cylindrical members are in a tightly fitted filling without gaps; and during bonding, the vertical setting can make the opening of the filling gap located directly above, which is convenient for glue pouring operation, and at the same time, the glue automatically flows downward and fills under the action of its own gravity, with good filling effect and high efficiency, and vertical glue pouring is also convenient for workers to control the glue pouring position, and too much glue will not gather on the outermost side of each cylindrical member, thereby facilitating demoulding and eliminating many defects of horizontal placement.

[0052] like Figure 3As shown, the outer cover body 1 includes a first baffle plate 11, a first side plate 12, and a second side plate 13. The first baffle plate 11, the first side plate 12, and the second side plate 13 are connected in a U shape. A first positioning member 2 is installed inside the first side plate 12, and a second positioning member 3 is installed inside the second side plate 12. A grid plate 66 is provided at the bottom of the inner part of the outer cover body 1, and the bottom of the grid plate 6 is an adhesive recovery chamber; the glue flowing vertically downward can pass through the grid plate downward, and then gather in the adhesive recovery chamber for easy recovery and storage.

[0053] like Figure 3 As shown, the first positioning member 2 and the second positioning member 3 have the same structure. The first positioning member 2 includes a first screw 21 and a first clamping plate 22. The first screw 21 vertically spirally penetrates the first side plate 12. The inner end of the first screw 21 is provided with a circular first clamping plate 22. The circular first clamping plate is convenient for clamping and positioning, and is easy to adjust using a screw.

[0054] like Figure 3 As shown, the third positioning member 4 includes a second baffle plate 41, a second screw rod 42 and a second clamp plate 43. The inner wall of the end portion of the first side plate 12 is provided with a first slot 121, and the inner wall of the end portion of the second side plate 13 is provided with a second slot 131. The second baffle plate 41 is inserted between the first slot 121 and the second slot 131. The internal thread of the second baffle plate 41 is penetrated by the second screw rod 42. The inner end of the second screw rod 42 is provided with a second clamp plate 43, and the second clamp plate 43 is relatively arranged between the two first clamp plates. After the first positioning member and the second positioning member are adjusted and positioned, the second screw rod is rotated to drive the second clamp plate to move inward and outward, and the second clamp plate clamps the positioning cylindrical member inward. The width of the second clamp plate is smaller than the distance between the two first clamp plates, and the two will not conflict with each other.

[0055] like Figure 4 As shown, the second magnetic material wire cutting machine includes a supporting template 5, which includes a base 51, a third baffle 52, a movable pressure plate 53, a third screw 54 and a fixed plate 55. The third baffle 52 is vertically provided at one end of the surface of the base 51, and the movable pressure plate 53 is vertically slidably installed at the other end of the surface of the base 51. A fixed plate 55 is provided on the outer side of the movable pressure plate 53, and the fixed plate 55 is arranged on the base 51. The internal thread of the fixed plate 55 passes through the third screw 54, and the end of the third screw 54 is rotatably connected to the movable pressure plate 53. The third baffle 52 and the movable pressure plate 53 are used to clamp and position the two ends of the cylindrical part that is bonded as one; the cylindrical part can be clamped and positioned from both ends by the third baffle and the movable pressure plate to ensure stability during wire cutting. In the past, there was a lack of positioning structure, which was easy to offset during placement and had processing errors.

[0056] like Figure 1As shown, a production method for processing a ferrite magnetic disc from a block comprises the following steps:

[0057] S1. Pour magnetic powder into the prepared block mold; the magnetic powder includes adhesive, iron powder, rare earth powder and additives;

[0062] S6, finishing the cylindrical blank by a centerless external circular grinding machine, and trimming the cylindrical blank into a cylindrical part;

[0063] S7, vertically placing the cylindrical rectangular array in the bonding platform, and filling adhesive into each internal gap, so that the cylindrical members arranged in the rectangular array are bonded as a whole;

[0064] S8, installing the cylindrical member bonded as one on the support template, and cutting the cylindrical member bonded as one into a plurality of circular pieces bonded as one by a second magnetic material wire cutting machine;
