Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for circuit board surface mounting, specifically to an auxiliary device for surface mounting components on bulk printed circuit boards. Background Technology

[0002] Printed circuit boards (PCBs) require surface mount technology (SMT) to meet the needs of different functional PCBs. SMT is a circuit assembly technology that mounts leadless or short-lead surface mount components (SMC / SMD) onto the surface of a PCB or other substrate, and then solders them using methods such as reflow soldering or dip soldering. This technology gives PCBs advantages such as high assembly density, small size and light weight of electronic products, high reliability, strong shock resistance, low solder joint defect rate, and good high-frequency characteristics.

[0003] Currently, the mounting of components for small-batch or single-batch printed circuit board (PCB) assemblies is done using a single-board-level matching model. These components are packaged as loose granules, making automated equipment like pick-and-place machines unsuitable for mounting. In such cases, manual mounting is the only option. Because there are many types of PCB materials, and the mounting locations vary, the mounting process requires visually locating the mounting positions according to the electrical assembly diagram before picking up the components and placing them in the corresponding locations. This is extremely inefficient and prone to errors. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for surface mount components on bulk printed circuit boards, so as to solve the problems of low efficiency and easy mismounting when mounting components on printed circuit boards in the existing single-board-level matching mode.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] An auxiliary device for surface mount components on bulk printed circuit boards includes: a support frame, a worktable disposed on top of the support frame, a controller disposed on the support frame, a vertical frame disposed on top of the worktable, a display disposed on the vertical frame and communicatively connected to the controller, and a rotary dispensing mechanism disposed on the support frame and communicatively connected to the controller, wherein the rotary dispensing mechanism is located below the worktable.

[0007] The rotary material distribution mechanism includes an indexing plate mounted on a support frame and located below the worktable, a rotary drive component connected to the input shaft of the indexing plate and communicating with the controller, a turntable mounted on the output shaft of the indexing plate and corresponding to the worktable, and several material distribution boxes mounted on the top of the turntable and evenly distributed along the circumference of the turntable's rotation axis. The worktable is provided with material picking slots corresponding to the material distribution boxes.

[0008] Furthermore, all of the aforementioned material distribution boxes are located at the top outer edge of the turntable.

[0009] Furthermore, all of the aforementioned material distribution boxes are the same size.

[0010] Furthermore, the dimensions of the aforementioned material receiving trough correspond to the dimensions of a single material distribution box.

[0011] Furthermore, the aforementioned support frame includes two sets of supports arranged opposite each other, a lower crossbeam located at the bottom of the two sets of supports, and an upper crossbeam located on the two sets of supports and near the top. The worktable is located on the top of the two sets of supports, the controller is mounted on the lower crossbeam, and the indexing plate is located on the upper crossbeam.

[0012] Furthermore, the length and width of the aforementioned worktable are both greater than the diameter of the turntable.

[0013] Furthermore, the aforementioned turntable is provided with mounting through holes.

[0014] This utility model has the following beneficial effects:

[0015] 1. The auxiliary device for surface mount components of bulk printed circuit boards of this utility model is provided with a rotating material distribution mechanism. The material distribution boxes are evenly distributed circumferentially on the top of the turntable. The rotating drive is connected to the controller to drive the indexing plate to achieve circumferential rotation, thereby realizing the indexing function. One index corresponds to one material distribution box. The material distribution box is used to place the components required for mounting. The display is used to display the specification information, coordinates, orientation, etc. of all components in the material distribution box. Therefore, when mounting printed circuit boards, the operator can transport the corresponding components to the picking slot of the worktable by operating the display and the controller. The operator can pass through the picking slot and take out the components from the material distribution box for mounting. Before mounting, staff place all loose components in their corresponding distribution boxes according to specifications. During mounting, staff operate the controller based on the specifications of the components to be mounted. The controller drives the indexing plate to rotate via a rotary drive, and the specifications of the components to be mounted are displayed on the monitor, along with the mounting position and orientation. The selected components are then transported to the bottom of the pick-up slot on the workbench, making it easy for staff to retrieve them from the distribution box and mount them onto the corresponding positions on the printed circuit board. This process completes the mounting of all components. The operation is simple and convenient, significantly improving mounting efficiency. It also keeps the workbench clean, preventing component mixing or loss.

[0016] 2. The auxiliary device for surface mounting of bulk printed circuit boards of this utility model is generally required to mount components on both sides of a printed circuit board. Most components are distributed on both sides of the printed circuit board. By using a rotating feeding mechanism in conjunction with a display and controller, all components of one specification on the first side of the product can be mounted at once without having to count the materials multiple times. When mounting the second side, the component specifications on the second side can be selected one by one to complete the mounting. Attached Figure Description

Furthermore, in order to facilitate material handling, the workbench 2 is provided with a material handling slot 21 corresponding to the material distribution box 64; the size of the material handling slot 21 corresponds to the size of a single material distribution box 64.

[0025] In this embodiment, the length and width of the worktable 2 are both greater than the diameter of the turntable 63. To facilitate the installation of the turntable 63 and reduce its weight, the turntable 63 is provided with mounting through holes. In this embodiment, four mounting through holes are provided and are evenly distributed in the middle of the turntable 63.

[0026] This utility model discloses an auxiliary device for surface mount components on bulk printed circuit boards.

This completes the mounting of all components. The operation is simple and convenient, significantly improving mounting efficiency. Furthermore, it keeps the workbench 2 clean, preventing component mixing or loss.
