[0042] Reference Figure 1 , the feeding device provided in the present application includes a frame 1, a material placing mechanism 2, a material picking mechanism 3, and a feeding driving mechanism 4. Among them, the material placing mechanism 2 includes a storage rack 21, at least a pair of slide rails 22, and at least one tray assembly 23. The storage rack 21 is supported on the frame 1; the slide rails 22 are fixed to the storage rack 21. The tray assembly 23 is slidably installed on the slide rails 22 and is used to hold materials. The material picking mechanism 3 is arranged on the frame 1 and is used to pick materials from the tray assembly for assembly. The feeding driving mechanism 4 is arranged on the material placing mechanism 2 and is used to drive the tray assembly 23 to move in a direction towards or away from the material picking mechanism 3.

[0043] One end of the storage rack 21 away from the material picking mechanism 3 is the material picking area, and the end away from the material picking mechanism 3 is the material preparation area. The material can be a double-row pin connector. The material is placed in the tray assembly 23 and stored at the storage rack 21. During feeding, the feeding driving mechanism 4 drives the tray assembly 23 to move along the slide rail 22 and approach the material picking mechanism 3. After moving to the material picking area at the material picking mechanism 3, the material picking mechanism 3 picks up the materials in the tray assembly 23 in sequence and picks them up to an installation position such as a PCB board for installation and assembly. When the materials in the tray assembly 23 are picked up completely, the feeding driving mechanism 4 can drive the empty tray assembly 23 to move away from the material picking mechanism 3 to the material preparation area of the storage rack 21 to complete one round of feeding, and this can be cycled. The feeding device of the present application has a simple structure and is easy to operate. It does not require manual feeding, greatly reduces the error rate of manual picking and connection by staff, improves the quality reliability of the connection process, and improves the production efficiency. At the same time, it can be applied to an automatic assembly production line to realize intelligent production.

[0044] In some embodiments, a plurality of rollers are uniformly arranged in the slide rail 22 to assist the movement of the tray assembly 23.

[0045] As an optional implementation manner, one end of the slide rail 22 is close to the material picking mechanism 3. The slide rail 22 is used to provide guidance for the tray assembly 23 so that the tray assembly 23 can move along the slide rail 22 to the material picking mechanism 3, for example, move to the lower part of the material picking mechanism 3. The material placing mechanism includes a plurality of tray assemblies 23. The tray assemblies 23 are arranged at intervals in the vertical direction on the storage rack 21 through the slide rail 22. The tray assemblies 23 are stacked on the storage rack 21 at intervals, thereby increasing the storage capacity and feeding amount of the materials, and further improving the feeding efficiency. When the feeding device with a plurality of tray assemblies 23 feeds materials, the feeding driving mechanism 4 drives one of the tray assemblies 23 to move along the corresponding slide rail 22 to the material picking mechanism 3. After the material picking mechanism 3 finishes picking up the materials in the tray assembly 23, the feeding driving mechanism 4 drives the empty tray assembly 23 away from the material picking mechanism 3 and returns it to the material preparation area of the storage rack 21. Then the feeding driving mechanism 4 drives another tray assembly 23 with materials on the storage rack 21 to move to the material picking mechanism 3 for feeding. Similarly, after feeding is completed, it is driven away from the material picking mechanism 3 and returned to the material preparation area. This is repeated until the materials in all the plurality of tray assemblies 23 are fed completely.

[0046] Reference Figure 2 , as an optional implementation manner, the tray assembly 23 includes a bottom tray 231, a guiding roller 232 and a tray 233.

The tray 233 is installed between the bottom tray 231 and the guiding roller 232, and the tray 233 is guided and limited on the bottom tray 231 through the guiding roller 232.

[0047] The tray 233 is used to hold materials. The bottom tray 231 is used to carry the tray 233. There may be multiple guiding rollers 232, which can be respectively arranged in the vertical direction or the lateral direction of the tray 233, and the rolling surfaces of the guiding rollers 232 are in contact with the surface of the tray 233 to help the tray 233 slide horizontally straight into the bottom tray 231. A limiting groove matching with the guiding roller 232 may also be arranged on the surface of the tray 233 to improve the guiding effect when the tray 233 is placed on the bottom tray 231.

[0048] Reference Figure 3 , As an optional implementation manner, the tray 233 includes a tray body 2331, a positioning member 2332, and a handle 2333. The tray body 2331 is located on the bottom tray 231, and a material placing groove 2334 is formed on its upper surface for storing materials. The positioning member 2332 limits the tray body 2331 to the bottom tray 231. The handle 2333 is fixed to the side of the tray body 2331.

[0049] The material placing groove 2334 is used to store materials. The handle 2333 is used to facilitate the pulling and placing of the tray body 2331. The positioning member 2332 limits the tray 233 to the bottom tray 231 to improve the positioning accuracy and stability of the tray 233 at the bottom tray 231.

[0050] In some embodiments, the positioning member 2332 can be a pin.

[0051] Reference Figure 3 , As an optional implementation manner, the inner wall of the material placing groove 2334 can be set according to the shape of the material to match the material. A material taking gap is arranged in the material placing groove 2334 for providing a picking space for the material taking mechanism 3 to improve the convenience when the material taking mechanism 3 picks up materials.

[0052] As an optional implementation manner, both ends of the material placing groove 2334 are arc-shaped.

[0053] As an optional implementation manner, a lining member is arranged in the material placing groove 2334 for protecting the materials in the material placing groove 2334.

[0054] Through the lining member, the materials are suspended in the material placing groove 2334 to avoid the deformation of the pins, thereby protecting the materials, reducing losses, and improving the yield rate of assembly.

[0055] In some embodiments, the lining member can include flexible materials such as sponge.

[0056] As an optional implementation manner, the tray assembly 23 is provided with at least one of a full material confirmation element and a position sensing element. The full material confirmation element is used to confirm the material loading condition in the tray assembly 23, and the position sensing element detects and senses the moving position of the tray assembly 23. For example, it judges and calibrates that the tray assembly 23 is located in the material preparation area or the material taking area.

[0057] Reference Figure 1 , as an alternative implementation, the loading driving mechanism 4 includes a driver and a traction member. The driver is disposed on the storage rack 21. One end of the traction member is connected to the driver, and the other end of the traction member is connected to the tray assembly 23. The driver drives the tray assembly 23 to approach or move away from the material picking mechanism 3 through the traction member.

[0058] In some embodiments, the driver can be a cylinder, and the traction member can be a traction rod.

[0059] Reference Figure 1 , as an alternative implementation, the material picking mechanism 3 includes a moving driving assembly 31 and a material picking member 32. Among them, the moving driving assembly 31 is disposed on the frame 1. The material picking member 32 is connected to the moving driving assembly 31 and is used for picking up materials. The moving driving assembly 31 drives the material picking member 32 to approach the materials for picking up or carry the materials to the assembly position.

[0060] In some embodiments, the moving driving assembly 31 may include a lateral moving assembly and a longitudinal moving assembly. The lateral moving driving assembly and the longitudinal moving driving assembly respectively drive the material picking member 32 to move laterally or longitudinally. Among them, the lateral moving driving assembly, the longitudinal moving driving assembly of the moving driving assembly 31 and the material picking member 32 can all be driven by a motor or pneumatically. The material picking member 32 can pick up or suck the materials by using a fixture, a vacuum chuck or a magnetic attraction element, etc.
