Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, and in particular relates to a feeding device for magnetic performance detection. Background Art

[0002] Magnetic property testing is a testing step in the NdFeB production process. Because NdFeB test pieces are inherently magnetic, if they fall into the testing chamber of the testing instrument during placement, they will be adsorbed by the metal magnetic testing chamber. Due to the strong magnetism of NdFeB, removing the test piece after adsorption takes time. Due to the small space in the testing chamber, manually placing and removing NdFeB test pieces is inconvenient. Therefore, a feeding device is needed that can prevent NdFeB test pieces from adsorbing to the bottom of the testing chamber and facilitate placement and removal of NdFeB test pieces.

[0003] Patent document number CN218965660U discloses a positioning and feeding device for wood processing, comprising a feeding table, the front of which is fixedly connected to a docking plate, a top surface of which is provided with a chute, and a movable plate slidably connected to the inner bottom wall of the chute. The positioning and feeding device for wood processing places the wood in a positioning frame, with its back side overlapping the front of two push plates. The second motor is then turned on, causing a bidirectional screw to drive the two strip plates toward each other until the two strip plates abut the left and right sides of the wood. The first motor then drives the movable plate and the positioning frame forward via the screw. When the wood reaches the processing table, the third motor is turned on and, via the screw, drives the two push plates to move the wood to a fixed position on the processing table. Due to the squeeze and limit of the two strip plates, the wood is prevented from deflecting during the pushing process, resulting in a relatively accurate position of the wood on the processing table, thereby improving the positioning and feeding efficiency of the wood. The drive method of this patent differs from that of the present application and requires a driver, which increases the cost of use and has a lower speed in the screw drive direction.

[0004] The patent document with announcement number CN212494996U discloses a hydraulic combined punching and shearing machine feeding device, which includes a first pushing assembly and a second pushing assembly. The first pushing assembly includes a conveying platform, a fixed frame, a threaded rod, a first driving member and a threaded sleeve. The second pushing assembly includes a second driving member, a connecting rod and a push plate. When in use, the threaded rod is driven to rotate by the first driving member, and the threaded rod drives the threaded sleeve to move. The threaded sleeve then drives the second pushing assembly to move through the connecting rod, and then pushes the plate onto the processing platform of the punching and shearing machine, and then starts the second driving member. The piston rod of the second driving member extends, driving the push plate to move, and continues to push the plate to the processing position. The driving method of this patent is different from that of the present application. It requires the drive of the driving member, but it will lead to an increase in the cost of use, and the speed of the screw driving direction is relatively low.

[0005] Patent document CN219751253U discloses a manual discharge mechanism comprising a mechanism container, a push-pull frame, and a material receiving basket. The mechanism container has a feed port, a discharge port, and a discharge port. Two chute bodies are disposed within the mechanism container, spaced apart along the left and right directions. A limit slot is disposed at the front of the push-pull frame, and a rotating shaft and a slider are disposed on the left and right sides of the middle portion of the material receiving basket, respectively. The slider is located behind the rotating shaft and slidably disposed above the push-pull frame. The material receiving basket can move forward relative to the push-pull frame until the rotating shaft extends into the limit slot, and the rotating shaft can rotate within the limit slot. The left and right sides of the push-pull frame are slidably connected to the two chute bodies. This patent realizes material movement and transportation by manually pushing and pulling the material receiving basket, and discloses the movable structure of the push-pull frame. However, this patent only allows for movement after collecting materials, and does not allow for the function of unloading materials at any position selected within the moving range of the material receiving basket.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0026] Example:

[0027] like Figures 1 to 6 As shown, a feeding device for magnetic property testing includes a base plate 1 and a feeding assembly 2. The base plate 1 is provided with a slide groove A11 and a positioning groove 12. The feeding assembly 2 includes a support frame 3, a feeding frame 4, a feeding plate 5 and a support column 6. The support frame 3 is connected to the base plate 1 via the support column 6. The feeding frame 4 and the feeding plate 5 are arranged on the support frame 3. The base plate 1 is made of non-magnetic, non-metallic material.

[0028] The support frame 3 is a frame structure, and a slide groove B31 and a slide groove C32 are set on the support frame 3. The slide groove B31 is set above the groove C32. The slide groove B31 and the slide groove C32 are symmetrically set at two locations. The feeding frame 4 is placed in the slide groove B31 for sliding connection, and the feeding plate 5 is placed in the slide groove C32 for sliding connection.

[0029] A through hole A33 is provided at one end of the support frame 3, and a through hole B34 is provided at one end of the slide groove B31 to facilitate the extension of the connecting rod A41 and the connecting rod C43. The length of the feeding plate 5 is smaller than the length of the slide groove C32.

[0030] The feeding frame 4 includes a connecting rod A41, a connecting rod B42 and a connecting rod C43. The connecting rod A41 is connected through the connecting rod B42 and the connecting rod C43. The connecting rod A41 and the connecting rod C43 are parallel. The connecting rod B42 is perpendicular to the connecting rod A41 and the connecting rod C43. The length of the connecting rod A41 is greater than the length of the connecting rod C43.

[0031] A pull rod 51 is provided at one end of the feeding plate 5 . The length of the feeding plate 5 and the pull rod 51 is greater than the length of the support frame 3 . The pull rod 51 extends out of the support frame 3 through the through hole A33 .

[0032] An opening 13 is provided at one end of the chute A11 for the protruding structure 91 of the magnetic detection instrument 9 to enter the chute A11 , and an arc-shaped portion 14 is provided at the other end of the chute A11 , corresponding to the shape of the protruding structure 91 .

[0033] The chute A11 is provided with baffles A7, which are positioned on both sides of the top of the chute A11. The thickness of baffles A7 is less than the depth of the chute A11. Baffles A7 can be made of a soft material such as rubber or silicone. They do not interfere with the sliding of the protruding structure 91 in the chute A11. In a natural state, they can close the top of the chute A11, preventing the test piece from contacting the magnetic detection instrument 9 through the chute A11 during removal, causing magnetic attraction and connection, which would make removal difficult.

[0034] The positioning groove 12 is arc-shaped, corresponding to the shape of the test table 92 of the magnetic detection instrument 9, so as to fit the test table 92. A baffle B8 is set on the top of the positioning groove 12. The baffle B8 can be made of soft materials such as rubber or silicone, so that the positioning groove 12 can better fit the test table 92. When removing the test piece from the test table 92, it can slide smoothly onto the bottom plate 1 to avoid contact with other positions of the magnetic detection instrument 9 to cause magnetic connection, which in turn makes removal difficult.

[0035] A method for using a feeding device for magnetic property detection comprises the following steps:

[0036] S1: Align the two slide grooves A11 with the protruding structure 91 and place it into the detection chamber of the magnetic detection instrument 9 until the positioning groove 12 is in contact with the test table 92;

[0037] S2: Pull the feeding frame 4 to the exit of the detection chamber of the magnetic detection instrument 9 through the connecting rod A41, pull the feeding plate 5 out to the exit of the detection chamber of the magnetic detection instrument 9 through the pull rod 51, and then place the test piece on the feeding plate 5.

[0038] S3: Push the pull rod 51 so that the feed plate 5 drives the test piece to the other side of the support frame 3. At this time, the feed plate 5 is located above the test table 92. Push the connecting rod A41 until the feed frame 4 contacts the test piece. Then pull the pull rod 51 outward. The test piece remains stationary under the limit of the feed frame 4. After the feed plate 5 is pulled away, the test piece falls onto the test table 92. After removing the feeding device, the test can begin.

[0039] S4: After the test is completed, the feeding frame 4 is moved close to one side of the positioning groove 12, and the feeding plate 5 is moved away from one side of the positioning groove 12, and then the feeding device is installed again. During the loading process, one side of the positioning groove 12 is lifted so that the test piece can be located in the support frame 3, and the connecting rod A41 is pulled to move the feeding frame 4 away from the positioning groove 12, driving the test piece to fall onto the bottom plate 1, and then the feeding device is taken out.
