Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

[0037] To simplify the description of this embodiment, some components that are well-known to those skilled in the art but are not related to the main content of this invention may be omitted in the accompanying drawings or description. Additionally, for ease of description, some components in the drawings may be omitted, enlarged, or reduced, but these do not represent the actual product dimensions or the complete structure.

[0038] An integrated powder adding and feeding device, such as Figure 1 As shown, it includes a connecting frame 8 that slides on a slide rail 7, and a powder adding mechanism 102 and a feeding mechanism 104 disposed on the connecting frame 8, that is, the powder adding mechanism 102 and the feeding mechanism 104 are integrally disposed on the connecting frame 8.

[0039] like Figures 2-4 As shown, the feeding mechanism 104 includes a rotary drive component 1, a clamping drive component 2, two clamping arms 4, and a floating component 3 disposed between the rotary drive component 1 and the clamping drive component 2.

[0040] The two clamping arms 4 are driven by the clamping drive unit 2 to open / close with each other to clamp and transfer the magnetic powder product 10, or to release the clamped product 10.

[0041] like Figure 2 , Figure 4 As shown, the clamping drive component 2 is connected to the floating component 3. After the clamping arm 4 clamps the product 10, the rotation drive component 1 drives the combination of the floating component 3, the clamping drive component 2, and the clamping arm 4 to rotate, causing the two clamping arms 4 to rotate from a vertically parallel state to a horizontally vertical state, as shown. Figure 7 , Figure 8 As shown, this changes the vertical clamping state of product 10 to a lifting state, eliminating the possibility of product 10 slipping off the clamping arm 4 due to its own weight, and ensuring the integrity and stability of product 10 during the transfer process. When product 10 is transferred to its destination, the rotary drive component 1 drives the combination of floating component 3, clamping drive component 2, and clamping arm 4 to rotate in opposite directions, causing the two clamping arms 4 to rotate from a horizontal up-down state to a position similar to... Figure 3The vertical parallel state is shown, the product 10 is loosened and placed to the specified position, so that the transfer of the product 10 is completed.

[0042] Preferably, the rotating driving part 1 is a rotating cylinder, and the clamping driving part 2 is a clamping cylinder.

[0043] The clamping arm 4 is provided with the detachable supporting plate 5, so that the utility model not only can be used for taking and transferring the product 10 with large volume and large weight, but also can be used for taking and transferring the conventional product 10, and when used for taking and transferring the conventional product 10, the supporting plate 5 can be removed. Of course, the supporting plate 5 is provided in various specifications and sizes, so as to adapt to different specifications of the product 10, so that different sizes of the supporting plate 5 can be replaced for different specifications of the product 10.

[0044] The supporting plate 5 need not be installed on both clamping arms 4, but only needs to be provided on the clamping arm 4 located at the lower side after rotation.

[0045] In order to facilitate the removal of the supporting plate 5, the supporting plate 5 is provided with a slot, the slot is adapted to the width and thickness of the clamping arm 4, and the clamping arm 4 can be directly inserted into the slot of the supporting plate 5, so that the supporting plate 5 is more convenient to replace.

[0046] As shown in Figure 3 、 Figure 4 The floating part 3 is further provided between the rotating driving part 1 and the clamping driving part 2, the floating part 3 comprises a bottom plate 31, a floating plate 32, a cover plate 33 and an elastic member 34, one cover plate 33 is arranged on each side of the bottom plate 31, the bottom plate 31 is provided with a sliding groove, the floating plate 32 is provided with a protruding sliding strip, the sliding strip is arranged in the sliding groove, the floating plate 32 is slidably connected with the bottom plate 31 and slides between the two cover plates 33, preferably, the bottom plate 31 is provided with two parallel sliding grooves, and the floating plate 32 is correspondingly provided with two parallel sliding strips; the elastic member 34 is arranged between the two sides of the floating plate 32 and the cover plate 33, the elastic member 34 is arranged between the sliding strip of the floating plate 32 and the cover plate 33, two elastic members 34 are arranged on each side, and the elastic member 34 usually uses a spring. The clamping driving part 2 is connected with the floating plate 32, and the rotating driving part 1 is connected with the bottom plate 31.

[0047] When the feeding component 104 clamps the product 10, the product 10 ejected from the mold 6 cannot be guaranteed to be exactly in the middle of the two clamping arms 4 every time, so that the two clamping arms 4 can clamp both sides of the product 10 simultaneously. If the product 10 is biased to one side after ejection, one clamping arm 4 will touch the product 10 first. During the clamping process, the product 10 will inevitably move laterally, which may damage the product 10. To solve this problem, this utility model sets a floating component 3 between the rotary drive component 1 and the clamping drive component 2. The function of the floating component 3 is that when the clamping arm 4 tries to clamp the product, if one clamping arm 4 touches the product before the other clamping arm 4, the floating plate 32 slides on the base plate 31 under the elastic force of the spring, so that the other clamping arm 4 is close to the product 10, so that the product 10 is subjected to uniform force and the clamping is stable, and the product 10 will not move. This will prevent the product 10 from being displaced and damaged by the contact of one clamping arm 4.

[0048] The clamping drive component 2 is connected to the floating plate 32, and one side of the rotation drive component 1 is connected to the bottom plate 31; the other side of the rotation drive component 1 is fixed to the connecting frame 8.

[0049] A magnetic field compressor, such as Figure 5 As shown, the integrated powder feeding and feeding device includes the above-mentioned integrated powder weighing and feeding device, as well as a powder weighing device 101, a stamping and forming device 103, and a slide rail 7 disposed between the powder weighing device 101 and the stamping and forming device 103. The integrated powder feeding and feeding device is mounted on the slide rail 7 via its connecting frame 8. The stamping and forming device 103 is provided with a forming mold 6 for stamping magnetic powder into product 10.

[0050] The powder weighing device 101 weighs a certain amount of magnetic material powder to be processed and sends the weighed powder to the powder feeding mechanism 102. The powder feeding mechanism 102 then sends the magnetic powder into the mold 6 of the stamping and forming device 103. The mold 6 produces the formed magnetic material powder product 10. The feeding mechanism 104 then transfers the product 10 to the unloading point and unloads the product 10.

[0051] like Figure 1 As shown, a slider 9, driven by a drive mechanism, slides on the slide rail 7. A connecting frame 8 is mounted on the slider 9. The drive mechanism drives the slider 9 to slide, which in turn drives the integrated powder feeding and material feeding device to slide. A lifting mechanism 105 is provided, and the integrated powder feeding and material feeding device is mounted on the lifting mechanism 105.

[0052] In the specific implementation process, such as Figures 6-8 As shown, the connecting frame 8 has at least a first position state, a second position state, and a third position state, and the connecting frame 8 can switch between the three states under the action of the slider 9;

[0053] Combination Figure 5,like Figure 6 As shown, when the connecting frame 8 is in the first position, the powder feeding mechanism 102 on it feeds powder material onto the powder weighing device 101.

[0054] After the powder is added, the drive mechanism drives the connecting frame 8 and its upper device to slide to... Figure 7 In the second position shown, when the connecting frame 8 is in the second position, the feeding mechanism 104 on the connecting frame 8 is located above the forming mold 6, and the two clamping arms 4 of the feeding mechanism 104 first clamp the product 10.

[0055] The drive mechanism continues to drive the connecting frame 8 and its upper device toward Figure 8 The product 10 is slid in the third position shown. During the sliding process, the feeding mechanism 104 rotates and the two clamping arms 4 are in an up and down position, supporting the product 10.

[0056] When the connecting frame 8 is in the third position, the powder feeding mechanism 102 is located above the molding die 6, and the lifting mechanism 105 descends. The feeding port of the powder feeding mechanism 102 enters the molding die 6, adding powder material into the molding die 6. This prevents powder leakage, thus avoiding waste and pollution. At the same time, the lifting mechanism 105 also allows the integrated powder feeding and conveying device to adapt to molding dies 6 of different heights, making the device more flexible and adaptable.

[0057] Meanwhile, the feeding mechanism 104 is located at the unloading point of the product 10. The feeding mechanism 104 rotates to make the two clamping arms 4 vertical, and the two clamping arms 4 are released to unload the product 10. Subsequently, the lifting mechanism 105 rises, and the connecting frame 8 returns to the first position.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made within the scope of the claims of this utility model should be considered within the technical scope of this utility model.
