Description

Technical Field

[0001] This utility model relates to the field of feeding technology, specifically to a magnetic lifting feeding device. Background Technology

[0002] Currently, most lifting and feeding machines on the market employ complex gear transmission mechanisms. A motor drives the gears to rotate the track reciprocally, thus lifting parts from a lower position to a higher position, where they fall into a pre-set receiving tray, completing the lifting and feeding process.

[0003] However, due to its structure, this type of tracked lifting feeder is prone to track wear, and small materials can easily spill from the wear points, resulting in incomplete material cleaning and mixing during material switching in the workshop. In addition, small metal parts can easily enter the interior of various moving mechanical parts after spilling, causing damage to the gear transmission mechanism.

[0004] Based on the above background, the inventors have designed a magnetic lifting and feeding device that can solve at least one of the above problems, and hereby submit this application. Summary of the Invention

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 3As shown, this embodiment provides a magnetic lifting and feeding device, including a support 1, a magnetic lifting mechanism 2 and a receiving assembly 7 disposed on the support 1, wherein:

[0035] The magnetic lifting mechanism 2 includes a magnetic isolation box 21 and a magnetic assembly 22, as well as a lifting and pulling member and a lifting motor 24 for driving the lifting and pulling member to move up and down. The magnetic assembly 22 is located inside the magnetic isolation box 21 and can move up and down inside the magnetic isolation box 21. The end of the lifting and pulling member away from the lifting motor 24 is fixedly connected to the magnetic assembly 22.

[0036] It also includes a baffle structure 5 that is mounted on the bracket 1 and used to limit the upward movement of the magnetic isolation box 21.

[0037] This embodiment incorporates a magnetic lifting mechanism 2 and a receiving assembly 7. The magnetic lifting mechanism 2 includes a magnetic isolation box 21 and a magnetic assembly 22 that can move up and down within the magnetic isolation box 21. It also includes a lifting and pulling component and a lifting motor 24, as well as a baffle structure 5 that restricts the upward movement of the magnetic isolation box 21 at a certain height. The structure of this application is completely different from the tracked lifting and feeding mechanism in the prior art, making the overall structure simpler and more compact, with lower manufacturing and operating costs. At the same time, the magnetic lifting method can also avoid the problem of material accumulation and scattering everywhere, which is more conducive to on-site material management and can effectively solve the problems of the prior art.

[0038] In this embodiment, as Figure 1 As shown, it also includes a storage bin 3 located directly below the magnetic isolation box 21. The storage bin 3, filled with hardware parts, can be transferred to the area directly below the magnetic isolation box 21 using equipment such as forklifts.

[0039] Specifically, in this embodiment, such as Figure 3 As shown, the magnetic attraction assembly 22 includes a first guide rod 222, a guide sleeve 224 and a spring 223 fitted on the first guide rod 222, and the magnetic attraction assembly 22 also includes a connecting block 225 and a permanent magnet 221 respectively fixed to both ends of the first guide rod 222;

[0040] The guide sleeve 224 is fixedly connected to the top of the magnetic isolation box 21;

[0041] The lifting and pulling member is fixedly connected to the magnetic attraction component 22. By setting the spring 223, the permanent magnet 221 can be quickly reset into position.

[0042] Specifically, in this embodiment, such as Figures 1 to 3As shown, the baffle structure 5 is provided with a through hole 51 for the connector and the first guide rod 222 in the magnetic attraction assembly 22 to pass through. After the connector and the first guide rod 222 move upward through the through hole 51, they can drive the permanent magnet 221 to move upward, thereby reducing or eliminating the magnetic attraction force at the bottom of the magnetic attraction isolation box 21, thereby releasing the adsorbed hardware parts.

[0043] Specifically, in this embodiment, the magnetic isolation box 21 includes an isolation main structure 211 with an internal cavity, and a magnet receiving structure 212 disposed at the bottom of the isolation main structure 211 and protruding downward.

[0044] The magnet accommodating structure 212 has an accommodating groove whose shape is adapted to the permanent magnet 221 and is used to accommodate the permanent magnet 221. By setting the magnet accommodating structure 212, the adsorption area of ​​the magnetic isolation box 21 that can adsorb parts can be increased, thereby improving the adsorption efficiency.

[0045] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, the magnetic lifting mechanism 2 also includes a lifting sprocket 25 disposed on the output shaft of the lifting motor 24. The lifting and pulling member is a lifting chain 23 with one end resting on and meshing with the lifting sprocket 25 and the other end fixed to the magnetic suction assembly 22. In some embodiments, the lifting chain 23 can also be a steel cable, and the lifting sprocket 25 can be replaced with a turntable adapted to the steel cable. Technicians can set it as needed, which will not be elaborated here.

[0046] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, it also includes a proximity switch 8 mounted on the bracket 1 and used to detect the position of the magnetic isolation box 21.

[0047] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, it also includes a protective sleeve 4 disposed at the bottom of the baffle structure 5 to prevent parts from falling off;

[0048] The lifting and pulling member is installed through the protective sleeve 4, and the magnetic isolation box 21 can move freely inside the protective sleeve 4.

[0049] Specifically, in this embodiment, such as Figures 1 to 3 As shown, the receiving assembly 7 includes two movable receiving trays that are slidably connected to the bracket 1 in the horizontal direction, and a drive cylinder 72 for driving the movable receiving trays to move in the horizontal direction.

[0050] The movable receiving tray is also horizontally provided with a second guide rod for guiding the movement of the movable receiving tray.

[0051] In this embodiment, the receiving component 7 also includes two fixed receiving trays 74 located below the movable receiving tray. By setting the movable receiving tray and the fixed receiving tray 74, when the magnetic suction mechanism releases the material, the material will not fall back into the storage bucket 3, but will be transferred to the outlet of the fixed receiving tray 74.

[0052] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, it also includes two vibrating discs 6 located below the discharge ports of the two fixed receiving discs 74.

[0053] In this embodiment, during use, the lifting motor 24 first drives the lifting chain 23 to descend until the magnetic isolation box 21 extends into the storage bin 3. Since the magnetic component 22 inside the magnetic isolation box 21 has a permanent magnet 221, the hardware parts will be attracted to the magnetic isolation box 21 under magnetic attraction. Then, the lifting motor 24 drives the lifting chain 23 to rise until the proximity switch 8 senses that the top of the magnetic isolation box 21 is approaching or pressing against the baffle structure 5. At this time, the drive cylinder 72 drives the movable receiving trough 71 to move below the magnetic isolation box 21. After reaching its position, the lifting motor 24 continues to drive the lifting chain 23 to lift a certain distance. At this point, the magnetic isolation box 21... Unable to continue upward due to the obstruction of the baffle structure 5, the lifting chain 23 drives the permanent magnet 221 to move upward via the first guide rod 222. As the permanent magnet 221 moves upward, the magnetic attraction force on the hardware parts decreases. Under the action of gravity, the hardware parts fall into the movable receiving tray and continue to slide into the fixed receiving tray 74 and the vibrating tray 6. After the hardware parts on the magnetic isolation box 21 fall off, the lifting motor 24 releases the lifting chain 23. Under the action of the spring 223, the permanent magnet 221 resets, and the entire magnetic isolation box 21 regains its ability to attract hardware parts. The lifting motor 24 drives the lifting chain 23 to move downward to carry out the next round of lifting and feeding.

[0054] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
