[0002] NdFeB is a commonly used permanent magnet material, which is widely used in electronic products. After the processes of powder making, pressing, sintering and tempering, magnetic testing and grinding, the material needs to be trimmed by a cutting machine, and finally electroplated to make the finished product.

[0003] When using a cutting machine, a placement plate is placed on the shelf, and the material to be cut is placed on the placement plate.

After the lifting frame lifts the material, the material is transported to the cutting machine by the electric conveyor rollers for trimming. Control the electric push rod to move the push plates, and adjust whether the rotation direction of the push plates is restricted. The two push plates on the right push the placement plates and materials on the cutting machine to the left to the electric conveyor rollers. During transportation, the material will not tilt in the horizontal direction, thereby realizing the automation of material supply for NdFeB trimming processing and high work efficiency.

[0014] 2. The inclined surface 1 of the limiting rod 1 and the bent end of the limiting rod 2 can make the placement plate in transportation centered front and back, and position the placement plate to avoid displacement of the placement plate and the material when the electric conveyor roller transports the material.

[0015] 3. The two legs of the shelf are respectively inserted into the two limit openings. The shelf can be limited by sliding the card block so that the position of the shelf and the base is relatively fixed, avoiding the movement of the shelf on the ground during material transportation and ensuring normal material transportation.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0031] Embodiment 1: A material supply device for NdFeB trimming processing, referring to Figure 1-Figure 6 , including a base 2, a mobile frame 3, a lifting frame 4, a fixed frame 5, an electric conveying roller 6, a connecting frame 7, a translation frame 8, an electric push rod 9, a mobile plate 10 and a push plate 11. The base 2 is provided with a mobile frame 3 sliding on the Y axis, and the mobile frame 3 is driven by a linear drive mechanism 1. A lifting frame 4 sliding on the Z axis is provided on the left side of the mobile frame 3, and the lifting frame 4 is driven by a linear drive mechanism 2. The linear drive mechanism 1 and the linear drive mechanism 2 are both prior arts. In this embodiment, the linear drive mechanism 1 is specifically an electric slider, which drives the mobile frame 3 to move. The linear drive mechanism 2 is specifically a screw and a motor. The screw is rotatably connected to the mobile frame 3, and the screw is threadedly connected to the lifting frame 4. The motor drives The movable screw rotates to drive the lifting frame 4 to rise and fall; a fixed frame 5 is welded on the right side of the mobile frame 3, and a row of electric conveying rollers 6 are installed on the lifting frame 4 and the fixed frame 5. When the material is on the electric conveying roller 6, the electric conveying roller 6 is controlled to rotate, and the material can be conveyed by friction; the lifting frame 4 and the fixed frame 5 are fixedly connected with a connecting frame 7, and the connecting frame 7 is slidably connected with a translation frame 8 driven by an electric slide rail, and a pair of electric push rods 9 are bolted to the ends of the two translation frames 8 that are away from each other, and a moving plate 10 is fixedly connected to the telescopic rod of the electric push rod 9, and a push plate 11 is rotatably connected to the moving plate 10, and the two push plates 11 on the left are symmetrical with the two push plates 11 on the right; Figure 5 and Figure 6As shown, a rotating shaft portion 111, a cylindrical portion 112 and a right-angle portion 113 are provided on the upper portion of the push plate 11. The rotating shaft portion 111 is rotatably connected to the lower portion of the movable plate 10, the cylindrical portion 112 is connected to the rotating shaft portion 111, the cylindrical portion 112 is tangent to the bottom surface 81 of the translation frame 8, and the top of the right-angle portion 113 is in contact with the bottom surface 81 of the translation frame 8, thereby limiting the rotation direction of the push plate 11.

[0032] Initially, there are three layers of placement plates on the shelf 1, each of which is placed with materials for NdFeB trimming processing. The shelf 1 includes four legs. The shelf 1 stops on the left side of the movable frame 3. The height of a row of electric conveyor rollers 6 on the lifting frame 4 is aligned with the height of the top layer of the shelf 1, and the height of a row of electric conveyor rollers 6 on the fixed frame 5 is aligned with the height of the feed port of the cutting machine.

[0033] The electric slide rail on the left connecting frame 7 is controlled to drive the left translation frame 8 to translate to the left on the X-axis, driving the two moving plates 10 on the left and the two pushing plates 11 on the left to translate to the left together. When the pushing plate 11 contacts the right side of the material on the shelf 1, the pushing plate 11 is squeezed by the material. Since the cylindrical portion 112 is tangent to the bottom surface 81 of the translation frame 8, the left-moving pushing plate 11 will rotate counterclockwise with the rotating shaft portion 111 as the axis. When the pushing plate 11 moves to the left and passes to the left side of the material, the pushing plate 11 is separated from the material, and the pushing plate 11 rotates clockwise to reset under the action of gravity; then the electric The movable slide rail drives the left translation frame 8 to translate and reset to the right on the X-axis, driving the two movable plates 10 on the left and the two push plates 11 on the left to translate and reset to the right. When the push plate 11 contacts the left side of the placement plate, since the top of the right-angle portion 113 is in contact with the bottom surface 81 of the translation frame 8, the push plate 11 cannot continue to rotate clockwise around the rotating shaft portion 111. At this time, the push plate 11 can push the placement plate and materials on the shelf 1 to move to the right to the row of electric conveyor rollers 6 on the left, and at the same time control the rotation of the electric conveyor rollers 6, and the electric conveyor rollers 6 will completely transport the placement plate and materials to the top of the lifting frame 4.

[0034] Then control the linear drive mechanism 2 to drive the lifting frame 4 to rise, driving the row of electric conveying rollers 6 on the left to rise to the height flush with the row of electric conveying rollers 6 on the right, thereby automatically lifting the material above the lifting frame 4; then control the two electric push rods 9 on the right to drive the two moving plates 10 on the right to translate to the right on the X-axis, driving the two pushing plates 11 on the right to translate to the right, so that the right-angled parts 113 of the two pushing plates 11 on the right leave the bottom surface 81 of the right translation frame 8, so that the rotation direction of the two pushing plates 11 on the right is no longer restricted by the bottom surface 81, and the electric conveying rollers 6 are controlled to continue to rotate, and the row of electric conveying rollers 6 on the left transports the placement plate and the material to the row of electric conveying rollers 6 on the right, and the row of electric conveying rollers 6 on the right transports the placement plate and the material to the right. When the material contacts the two pushing plates 11 on the right, the material will push the two pushing plates 11 on the right to rotate counterclockwise, so that the material can pass over the two pushing plates 11 on the right, and finally the material is transported to the feed port of the cutting machine for trimming.

[0035] When the material trimming is completed, the two electric push rods 9 on the right side are controlled to drive the two moving plates 10 on the right side to translate to the left and reset on the X-axis, and the two push plates 11 on the right side are moved to the left and reset, and the right-angled parts 113 of the two push plates 11 on the right side are again attached to the bottom surface 81 of the right translation frame 8; then the electric slide rail on the right connecting frame 7 is controlled to drive the right translation frame 8 to translate to the right on the X-axis, driving the two moving plates 10 on the right side and the two push plates 11 on the right side to translate to the right together. After the push plate 11 contacts the left side of the material on the cutting machine, it is squeezed by the material. Since the cylindrical portion 112 is tangent to the bottom surface 81 of the translation frame 8, the two push plates 11 on the right side rotate clockwise with the rotating shaft portion 111 as the axis. When the push plate 11 moves rightward and passes to the right side of the material, the push plate 11 is separated from the material. The push plate 11 rotates counterclockwise and resets under the action of gravity; the translation frame 8 on the right side is driven by the electric slide rail to translate to the left on the X axis and reset, driving the two moving plates 11 on the right side. 0 and the two right push plates 11 translate to the left. When the push plate 11 contacts the right side of the placing plate, the top of the right-angled portion 113 is in contact with the bottom surface 81 of the translation frame 8, and the push plate 11 cannot continue to rotate counterclockwise with the rotating shaft portion 111 as the axis. At this time, the two right push plates 11 can push the placing plate and the material on the cutting machine to move to the left to the row of electric conveying rollers 6 on the right, and at the same time control the electric conveying rollers 6 to rotate, and the row of electric conveying rollers 6 on the right conveys the placing plate and the material to the left above the lifting frame 4, and the lifting frame 4 descends and resets, and controls the two electric push rods 9 on the left to drive the two moving plates 10 on the left to translate to the left on the X-axis, driving the two push plates 11 on the left to translate to the left, so that the right-angled portions 113 of the two push plates 11 on the left leave the bottom surface 81 of the left translation frame 8, so that the rotation direction of the two push plates 11 on the left is no longer restricted by the bottom surface 81. Similarly, the row of electric conveying rollers 6 on the left can convey the trimmed materials to the shelf 1 for storage.

[0036] By controlling the linear drive mechanism 1 to drive the movable frame 3 to translate in the Y-axis direction, the lifting frame 4, the fixed frame 5, the electric conveying roller 6, the translation frame 8 and the push plate 11 are driven to translate in the Y-axis direction. Similarly, the materials at different positions on the shelf 1 in the Y-axis direction can be transported; by controlling the linear drive mechanism 2 to drive the lifting frame 4 to move in the Z-axis direction, the height of a row of electric conveying rollers 6 on the lifting frame 4 is aligned with the height of different layers of the shelf 1, and the materials of different layers can be transported. In this way, there is no need for manual handling of materials, and the materials will not tilt in the horizontal direction during transportation. The material supply automation for NdFeB trimming processing can be realized, and the work efficiency is high.

[0037] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 The material supply equipment for NdFeB trimming processing also includes a limiting mechanism, which includes a fixed rod 121, a limiting rod 122 and a limiting rod 2 124. The lifting frame 4 and the fixed frame 5 are welded with the fixed rod 121, and a pair of limiting rods 122 are detachably connected to the fixed rod 121. The two limiting rods 122 on the right side extend to the left to just above the moving frame 3. The left ends of the pair of limiting rods 122 on the left and the right ends of the pair of limiting rods 122 on the right are both provided with an inclined surface 123. The lifting frame 4 and the fixed frame 5 are both symmetrically fixedly connected with the limiting rods 2 124 front and back, and the left ends of the two limiting rods 124 on the left and the right ends of the limiting rods 124 on the right are both provided with a bent end 125.

[0038] When the two pushing plates 11 on the left push the placement plate and materials on the shelf 1 to move to the right onto a row of electric conveyor rollers 6 on the left, the placement plate in transportation can be centered front to back through the inclined surface 123 of the limiting rod 122 and the bent end 125 of the limiting rod 2 124, and the two limiting rods 122 on the right both extend to the left to just above the moving frame 3, thereby positioning the placement plate in transportation. When the two pushing plates 11 on the right push the placement plate and materials on the cutting machine to move to the left onto a row of electric conveyor rollers 6 on the right, similarly, the placement plate is positioned through the limiting rod 122 and the limiting rod 2 124 to avoid the placement plate and material position shifting when the electric conveyor roller 6 transports the material.

[0039] Embodiment 3: Based on Embodiment 2, refer to Figure 1 and Figure 8The material supply equipment for NdFeB trimming processing also includes a positioning mechanism, which includes a connecting rod 131 and a sliding block 132. The connecting rod 131 is fixedly connected to the front side of the top of the base 2. Two sliding blocks 132 that slide on the X-axis are provided on the left side of the connecting rod 131. Reset springs are fixedly connected between the sliding blocks 132 and the connecting rod 131. Inclined surfaces 133 are provided on the rear sides of the sliding blocks 132. Limiting openings 134 that cooperate with the shelf 1 are formed between the sliding blocks 132 and the connecting rod 131.

[0040] Initially, the two legs of the shelf 1 are respectively inserted into the two limit openings 134, so that the shelf 1 is limited by the sliding block 132, so that the position of the shelf 1 and the base 2 is relatively fixed, and the shelf 1 is prevented from moving on the ground during the material transportation process, thereby ensuring the normal transportation of materials; when the transportation of materials on a shelf 1 is completed, the two sliding blocks 132 are manually pulled close to each other, and the reset spring is compressed, and the shelf 1 can be pushed to move backward. After the sliding block 132 is released, the reset spring restores the two sliding blocks 132 to move away from each other, and then the next shelf 1 is pushed, so that the two legs of the shelf 1 are respectively in contact with the two sliding blocks 132, and the legs squeeze the two sliding blocks 132 by squeezing the second inclined surface 133. When the legs are inserted into the two limit openings 134, the reset spring restores the two sliding blocks 132 to move away from each other, and the next shelf 1 can be limited.

[0041] Embodiment 4: Based on Embodiment 3, refer to Figure 9-11 The material supply equipment for NdFeB trimming processing also includes a pressing mechanism, which includes a connecting plate 141, a sliding rod 142, a pressing rod 143 and a transmission assembly. Two connecting plates 141 are welded on the fixed rod 121 on the left. Each connecting plate 141 is provided with a pair of sliding rods 142 sliding on the Z axis. A compression spring is fixedly connected between the sliding rod 142 and the connecting plate 141. Two pressing rods 143 are fixedly connected between the bottom of each pair of sliding rods 142. A transmission assembly for moving the pressing rod 143 up and down is provided on the fixed rod 121 on the left.

[0042] refer to Figure 1 , Figure 2 , Fig.10 , Fig.11 and Fig.12The transmission assembly includes a second connecting rod 151, a third connecting rod 153, a transmission rod 154, a movable rod 155 and a guide plate 156. The second connecting rod 151 is welded on the top of the fixed rod 121 on the left side. A horizontal straight groove 152 is opened on the upper part of the second connecting rod 151. A movable rod 155 that moves in the X axis is arranged in the groove 152. A third connecting rod 153 is welded between each pair of sliding rods 142. The middle parts of the two third connecting rods 153 are rotatably connected to the transmission rod 154. The tops of the transmission rods 154 are rotatably connected to the movable rod 155. The front and rear sides of the mobile frame 3 are fixed. A guide plate 156 is fixedly connected, and a guide groove 157 is opened on the side where the two guide plates 156 are close to each other. The front and rear ends of the movable rod 155 are respectively located in the two guide grooves 157; the guide groove 157 includes three V-shaped sections 1571 arranged at intervals, three vertical sections 1573 arranged at intervals and an inclined section 1572 located at the top. The number of V-shaped sections 1571 is equal to the number of layers of the shelf 1. When the end of the movable rod 155 moves to the vertical section 1573, the downward pressure rod 143 will move downward relative to the connecting plate 141, thereby pressing the material.

[0043] Initially, the front and rear ends of the movable rod 155 are respectively located in the uppermost V-shaped sections 1571 in the two guide grooves 157. When the lifting frame 4 rises to lift the placement plate and materials on the left row of electric conveying rollers 6, the fixed rod 121, the connecting plate 141, the sliding rod 142, the pressing rod 143, the second connecting rod 151, the third connecting rod 153, the transmission rod 154 and the movable rod 155 rise synchronously with the lifting frame 4. When the movable rod 155 leaves the V-shaped section 1571, the movable rod 155 enters the vertical section 1573 and moves in the guide grooves 157. Under the guidance of the groove 157 and the through groove 152, the movable rod 155 located in the through groove 152 will move leftward in the X-axis direction, and the movable rod 155 moves leftward relative to the second connecting rod 151, the fixed rod 121, the connecting plate 141, the sliding rod 142 and the third connecting rod 153. The leftward moving movable rod 155 drives the transmission rod 154 to rotate, and the rotating transmission rod 154 can make the third connecting rod 153, the sliding rod 142 and the lower pressure rod 143 descend relative to the connecting plate 141, and the compression spring is compressed, so that the lower pressure rod 143 presses the rising material When the row of electric conveying rollers 6 on the left side rises to the same height as the row of electric conveying rollers 6 on the right side, the two ends of the rising movable rod 155 move to the inclined section 1572, and the movable rod 155 moves rightward relative to the second connecting rod 151, the fixed rod 121, the connecting plate 141, the sliding rod 142 and the third connecting rod 153 to reset, and the third connecting rod 153, the sliding rod 142 and the lower pressing rod 143 are raised and reset relative to the connecting plate 141 through the transmission rod 154, and the lower pressing rod 143 no longer presses the material, and the material can be transported by the electric conveying roller 6. When the height of the row of electric conveyor rollers 6 on the left is aligned with the height of the other shelf 1 layer, the two ends of the movable rod 155 will be located in the V-shaped section 1571.
