Description

Technical Field

[0001] This utility model belongs to the technical field of material handling devices, specifically relating to a variable spacing feeding device. Background Technology

[0002] In the production and assembly of electronic products, to facilitate the turnover and storage of components, multiple components are usually evenly placed in a turnover tray. During assembly, the components are then removed and assembled. With technological advancements, the level of automation in industrial production is increasing, and more and more material handling devices are becoming widespread and applied. Compared to traditional manual material handling methods, these devices can handle multiple materials simultaneously, improving work efficiency and preventing the leaving of sweat stains and scratches on the surface of the components. For example, a utility model patent with authorization announcement number CN 216030884U discloses a variable-gap suction nozzle device, including a base plate, a lifting and fixing block, a lifting mechanism, a cam guide block, a horizontal sliding mechanism, and several suction nozzle assemblies. The cam guide block is movably mounted on the base plate, and the base plate is connected to the lifting and fixing block. The lifting mechanism is mounted on the lifting and fixing plate and connected to the cam guide block. The horizontal sliding mechanism is mounted on the base plate, and the suction nozzle assemblies are mounted on the horizontal sliding mechanism. Each suction nozzle assembly is provided with a cam follower. The cam guide block is provided with several U-shaped grooves for guidance, and the cam follower is located in the U-shaped grooves. The U-shaped grooves are inclined, and the spacing between each pair of adjacent U-shaped grooves is equally spaced from top to bottom or from bottom to top. The advantage of this design is that it can simultaneously pick up multiple parts, improving assembly efficiency. Moreover, the device has a simple and compact structure, high precision, is easy to control, and has good movement performance.

[0003] However, in actual production, due to factors such as the shape of the products to be assembled and the space of the assembly line, uneven spacing often occurs between different products at the assembly station. In this case, if the requirement for simultaneous assembly of multiple products is still needed, the center-to-center distance between adjacent nozzles must correspond to the spacing between the products to be assembled. In this technical solution, the distance between adjacent U-shaped grooves is set at equal intervals from top to bottom or bottom to top. This means that the distance between adjacent nozzles can only vary at equal intervals, which obviously cannot meet the requirement for simultaneous assembly of multiple products with uneven spacing. Therefore, it is necessary to improve the existing technology. Utility Model Content

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. However, those skilled in the art will understand that the embodiments described below are only some embodiments of this utility model, not all embodiments, and are only used to illustrate this utility model, and should not be regarded as limiting the scope of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall be followed. Where the manufacturers of reagents or instruments are not specified, they are all conventional products that can be purchased commercially.

[0027] like Figure 1-8As shown, a variable-pitch feeding device includes a main mounting base 1, on which a first picking mechanism 2 and a second picking mechanism 3 are provided. A transfer mechanism 4 is located below the main mounting base 1. Multiple picking components 214 are mounted on both the first picking mechanism 2 and the second picking mechanism 3. Specifically, the picking components 214 can be structures such as suction nozzles or pneumatic grippers, used to pick up or clamp parts. The transfer mechanism 4 includes a first mounting plate 401, on which multiple trays 402 are provided. Each tray 402 includes an active tray 4021. A driven pallet 4022 and a fixed pallet 4023 are provided. The fixed pallet 4023 is fixedly connected to the first mounting plate 401. The driven pallet 4022 is located between the active pallet 4021 and the fixed pallet 4023. The pallet 402 has positioning holes 4024 for accommodating parts. The picking component 214 corresponds to the positioning holes 4024. Adjacent pallets 402 are connected by connecting components 403 for limiting the spacing. The active pallet 4021 is connected to a first driving mechanism 5, which drives the active pallet 4021 to move. In actual use, the first picking mechanism 2 is used to transfer parts from the turnover box 6 to the transfer mechanism 4, and the second picking mechanism 3 is used to assemble the parts on the transfer mechanism 4 onto the product to be assembled. Specifically, the spacing between the components in the turnover box 6 is uniform, while the center-to-center spacing of the products to be assembled is unequal. For clarity and convenience, the spacing between the components in the turnover box 6 is set as x, and the center-to-center spacing of the assembly parts of adjacent products to be assembled is set as y0, y1, y2, ... . To enable the first picking mechanism 2 to pick up multiple components simultaneously, the center-to-center spacing of adjacent picking components 214 on the first picking mechanism 2 is equal to x. To enable the second picking mechanism 3 to assemble multiple components onto the products to be assembled simultaneously, the center-to-center spacing of adjacent picking components 214 on the second picking mechanism 3 is y0, y1, y2, ... . Before the pitch change, the spacing between the positioning holes 4024 on adjacent pallets 402 is equal to x; after the pitch change, the center-to-center spacing of the positioning holes 4024 on adjacent pallets 402 is y0, y1, y2, ... . Thus, the first picking mechanism 2 simultaneously picks up multiple parts and places them on the transfer mechanism 4. The first driving mechanism 5 drives the pallet 402 to move, changing the center distance between adjacent pallets 402. The connecting component 403 limits the distance between adjacent pallets 402 and makes the center distance between adjacent positioning holes 4024 correspond to the center distance of the assembly part of the corresponding product to be assembled. The second picking mechanism 3 picks up parts from the transfer mechanism 4 and assembles multiple parts into the corresponding product to be assembled at the same time, greatly improving the assembly efficiency.

[0028] In this embodiment, the connecting component 403 includes positioning posts 4031 and limiting blocks 4032. Positioning posts 4031 are installed on both the driven pallet 4022 and the fixed pallet 4023. Limiting blocks 4032 are fixedly installed on both the active pallet 4021 and the driven pallet 4022. Each limiting block 4032 has a sliding groove 4033. The length of the sliding groove 4033 extends parallel to the driving direction of the first driving mechanism 5. The length of the sliding groove 4033 matches the center-to-center distance of the corresponding product to be assembled. The sliding groove 4033 is slidably connected to the corresponding positioning post 4031, allowing the spacing between the pallets 402 to vary within a certain range. Specifically, when the active pallet 4021 moves away from the fixed pallet 4023, the center-to-center distance of the pallets 402 increases, with maximum distances of y0, y1, y2, etc. When the active pallet 4021 moves closer to the fixed pallet 4023, the center-to-center distance of the pallets 402 decreases, with minimum distances of x.

[0029] In this embodiment, the first driving mechanism 5 includes a first mounting base 501, on which a first guide rail 502 is fixedly mounted.

Second sliders 508 are fixedly mounted on the bottom of both the active support plate 4021 and the driven support plate 4022.

When the first cylinder 507 extends, it moves the active support plate 4021 away from the fixed support plate 4023, increasing the distance between the support plates 402. When the first cylinder 507 retracts, it moves the active support plate 4021 closer to the fixed support plate 4023, decreasing the distance between the support plates 402.
