Description

Technical Field

[0001] This utility model relates to the field of automated product feeding technology, specifically to a multi-station feeding device. Background Technology

[0002] In the production line, electronic products need to go through multiple processing steps to ensure good contact. For example, electronic products such as inductors and contactors need to undergo cutting and soldering operations. After cutting, the cut edges of electronic products will oxidize, and the cut edges and leads need to be soaked in flux containers and solder pots respectively to complete the soldering treatment. However, traditional electronic products have small appearance structures, and before the product soldering test, they are mostly loaded manually by placing the electronic products in the loading position, which requires a large amount of labor costs.

[0003] Later, automated production lines were introduced, and electronic products were mostly loaded using robotic arms and conveyor belts. However, using conveyor belts for loading is not conducive to the subsequent soldering process. Moreover, it is difficult to effectively fix electronic products on the conveyor line. Even if they are fixed, the products need to be removed from the conveyor belt for the subsequent soldering operation, which greatly increases the complexity of the operation.

[0004] Therefore, how to effectively fix electronic products after loading and achieve high-efficiency loading operations is a technical problem that urgently needs to be solved. Utility Model Content

[0005] Purpose of the utility model: To address the problems existing in the prior art, this utility model provides a multi-station feeding device that uses an electromagnet to fix the product to the welding rod for effective fixation, and simultaneously uses a hollow rotating module in the feeding section to rotate and set the welding rod clamp, thereby achieving multi-station feeding.

[0006] Technical Solution: This utility model provides a multi-station feeding device, including a frame, on which a robotic arm feeding module, a hollow rotating feeding module, and a welding rod group are mounted. The welding rod group includes a welding rod fixing rod with multiple welding rods spaced apart on it. A first electromagnet is mounted on the upper end of each welding rod, and the product is fixed by switching the first electromagnet on and off. The hollow rotating feeding module is equipped with at least one set of welding rod clamps, which hold the welding rod group. The robotic arm feeding module is used to grab the product onto the welding rods. The hollow rotating feeding module can rotate at a certain angle.

[0007] Furthermore, the robotic arm loading module includes a loading robotic arm, the end of which is equipped with an electric loading gripper. A ring light source and a camera are also provided on one side of the electric loading gripper at the end of the loading robotic arm. The camera faces the ring light source, and the ring light source faces the gripping direction of the electric loading gripper.

[0008] Furthermore, the hollow rotating module for feeding includes a rotating platform, at least one rotating cylinder, and a welding rod clamp. The rotating platform is equipped with a rotating drive assembly, and a rotating cylinder fixing component is fixedly mounted on the rotating platform. A rotating cylinder is fixedly connected to the rotating cylinder fixing component, and the actuating end of the rotating cylinder is connected to the welding rod clamp through a clamp fixing plate.

[0009] Furthermore, a second electromagnet is provided on each side of the clamp fixing plate, and the second electromagnet is positioned directly opposite the welding rod assembly.

[0010] Furthermore, the welding rod clamp has an outer opening and a cross-section of... A clamp shaped like a character.

[0011] Furthermore, the rotation drive component is a rotation servo motor, the output of which is connected to the rotation platform.

[0012] Furthermore, it also includes a carrier centering module, which includes a pair of centering cylinders. When the loading hollow rotating module clamps the welding rod group to a certain direction, the actuating end of the centering cylinder is directly opposite the position of the welding rod group of the loading hollow rotating module.

[0013] Furthermore, it also includes a welding rod group sorting module, which is located between a pair of centering cylinders. The sorting module includes sorting cylinders arranged vertically, a sorting platform located at the end of the sorting cylinders, and several sorting protrusions spaced apart on the sorting platform. When the loading hollow rotating module clamps the welding rod group to a certain direction, the sorting protrusions face the product on the welding rod group. Beneficial effects

[0014] 1. This utility model realizes the feeding operation through a hollow rotary module. During the feeding process, multiple rotary cylinders are set on the rotary platform to realize multi-station feeding. After the feeding of one station is completed, the rotary cylinder that needs to be fed is rotated to the feeding position by rotating the rotary platform. The rotary cylinder that has completed feeding and its welding rod clamp can hold the welding rod group and enter the next process. Through the circular station design, the product feeding, product transfer and other operations can be carried out simultaneously, which greatly improves the work efficiency.

[0015] 2. This utility model provides second electromagnets on both sides of the clamp fixing plate. By controlling the second electromagnets, the welding rod group can be attracted and fixed. The welding rod group is set facing upward at the loading station, but when grabbing the welding rod group in the next process, it needs to be set downward. This is achieved by rotating the cylinder to rotate 180 degrees, and the second electromagnet can ensure that the welding rod group will not fall during the rotation.

[0016] 3. This utility model has a first electromagnet on the welding rod assembly. The product and the welding rod assembly are connected by the first electromagnet. By controlling the on / off point of the first electromagnet, the connection between the product and the welding rod assembly can be controlled, and the product can be effectively fixed.

[0017] 4. The welding rod clamp designed in this utility model is as follows: The U-shaped opening fixture is designed to facilitate the removal of solder rods from one side of the soldering gantry module during later soldering.

[0018] 5. This utility model sets up a carrier centering module at the material loading station. A pair of centering cylinders can center the welding rod group so that the welding rod group is in the middle of the entire welding rod clamp. When the welding rod group is picked up to apply flux and tin in the subsequent process, it can also be kept in the middle position, which is convenient for control.

[0019] 6. The welding rod group sorting module of this utility model can sort the products on the welding rod group when the welding rod group is aligned by the sorting platform set at the end of the sorting cylinder, so that the products are neatly arranged on the welding rod group. During the subsequent fluxing and soldering, the distance can be accurately controlled to achieve soldering of the leads and cuts without affecting other positions of the products.

Detailed Implementation

The frame 4 is equipped with a robotic arm feeding module 2, a feeding hollow rotating module 1, and a welding rod group 3. The welding rod group 3 includes a welding rod fixing rod 303, on which multiple welding rods 301 are spaced apart. A first electromagnet 302 is provided at the upper end of the welding rod 301, and the product is fixed by switching the first electromagnet 302 on and off. The feeding hollow rotating module is equipped with at least one set of welding rod clamps 207, which clamp the welding rod group 3. The robotic arm feeding module is used to grab the product onto the welding rod 301. The feeding hollow rotating module can rotate a certain angle.

[0027] See Figure 2 The robotic arm loading module 2 includes a loading robotic arm 204, with an electric loading gripper 201 at its end for loading products. A ring light source 202 and a camera 203 are also located at the end of the loading robotic arm 204 on one side of the electric loading gripper 201. The camera 203 faces the ring light source 202, which is aligned with the gripping direction of the electric loading gripper 201, providing supplementary lighting for the camera 203 to capture images. A material pool 211 is located on one side of the frame 4, allowing the robotic arm loading module 2 to pick up products from the material pool 211 and place them onto the welding rod assembly 3.

[0028] The hollow rotary loading module 1 includes a rotary platform 205, at least one rotary cylinder 206, and a welding rod clamp 207. The rotary platform 205 is equipped with a rotary drive assembly, which is a rotary servo motor 208, the output of which is connected to the rotary platform 205. A rotary cylinder fixing member 209 is fixed on the rotary platform 205, and a rotary cylinder 206 is fixedly connected to the rotary cylinder fixing member 209. The actuating end of the rotary cylinder 206 is connected to the welding rod clamp 207 through a clamp fixing plate 210. In this embodiment, a pair of rotary cylinders 206 are provided, symmetrically arranged on the rotary cylinder fixing member 209.

[0029] The clamp fixing plate 210 is also provided with a second electromagnet 211 on both sides, and the second electromagnet 211 is positioned directly opposite the welding rod group 3.

[0030] In this embodiment, the welding rod clamp 207 has an outer opening and a cross-section of [missing information]. The U-shaped fixture has an opening on one side to facilitate the removal of the welding rod assembly 3 from the welding rod fixture 207 by the robotic arm in the subsequent process.

[0031] During loading, the welding rod group 3 is located inside the welding rod clamp 207 and is fixed by energizing the second electromagnet 211. At this time, the welding rod group 3 drives the welding rod 301 above to be set upward. The end of the loading robot arm 204 grabs the product and places it on the top of the welding rod group 3 through the electric loading gripper 201. The product is attracted and fixed by the first electromagnet 302 at the top of the welding rod group 3. After loading is completed, the rotating platform 205 rotates 180 degrees, and the rotating cylinder 206 on the other side drives the empty welding rod group 9 to the loading position to continue loading. The welding rod group 3 after loading can enter the next process.

[0032] In this embodiment, the multi-station feeding device also includes a carrier centering module 213, which includes a pair of centering cylinders 2131. When the feeding hollow rotating module clamps the welding rod group 3 to a certain direction, the actuating end of the centering cylinder 2131 is directly opposite the position of the welding rod group 3 of the feeding hollow rotating module.

[0033] See Figure 3 The purpose of the carrier centering module 213 is to place the welding rod group 3 in the center of the welding rod clamp 207. After the welding rod group 3 is clamped and rotated to a certain position by the hollow rotating module during loading, it is rotated 180 degrees by the rotating cylinder 206. The welding rod group 3 drives the product on it to rotate 180 degrees. After rotation, the product is facing downward. At this time, the second electromagnet 211 releases the welding rod group 3, and the centering of the welding rod group 3 is achieved by the carrier centering module 213.

When the feeding hollow rotating module clamps the welding rod group 3 to a certain direction, the sorting protrusions 2143 face the product on the welding rod group 3. In this embodiment, after the hollow rotating module clamps the welding rod group 3 carrying the product and rotates it 180 degrees, the rotating cylinder 206 rotates 180 degrees, and the welding rod group 3 drives the product on it to rotate 180 degrees as well. After rotation, the product is downward. At this time, the second electromagnet 211 releases the welding rod group 3, and the welding rod group 3 is centered by the carrier centering module 213. At this time, the sorting protrusion 2143 is facing the product on the welding rod group 3. The sorting cylinder 2141 pushes upward, and the sorting platform 2142 drives the sorting protrusion 2143 on it to squeeze the product of the welding rod group 3, so that the product is on a horizontal line.
