Description

Technical Field

[0001] This utility model relates to the field of PCB testing technology for advertising machines, and in particular to a double-sided testing device for PCB solder joints of advertising machines. Background Technology

[0002] An advertising display machine is an intelligent device controlled by terminal software that can display advertisements using multimedia materials such as images, videos, and widgets. During the production process of the advertising display machine's PCB (printed circuit board), solder joint inspection equipment is required to inspect the solder joints on both sides of the processed circuit board.

[0003] A search revealed that utility model publication number 202221630731 discloses a double-sided inspection device for solder joints of advertising machine PCB circuit boards. However, this device has the following drawbacks: when inspecting the advertising machine PCB, it is necessary to manually place the advertising machine PCB on two clamping seats, which not only reduces the inspection efficiency but also affects the inspection due to inaccurate placement. Therefore, we propose a double-sided inspection device for solder joints of advertising machine PCB circuit boards to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where manually placing the advertising machine PCB on two clamping seats not only reduces testing efficiency but also affects testing due to inaccurate placement. Therefore, this invention proposes a double-sided inspection device for advertising machine PCB solder joints.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-sided inspection device for PCB solder joints of an advertising machine includes a base. A support frame is fixedly mounted on the top of the base. An electric telescopic rod is fixedly connected through the support frame. A detection device is fixedly mounted on the output end of the electric telescopic rod. An opening is provided on the top of the base below the support frame. Two double-track conveyors are fixedly mounted on both sides of the opening on the top of the base. The two double-track conveyors are a loading conveyor and a unloading conveyor, respectively. A unloading port is provided on the base below the unloading conveyor, and the opening and the unloading port are connected. Two movable plates are slidably connected within the opening, and the bottoms of the two movable plates extend to the bottom of the base. The device also includes:

[0007] Two sets of conveyor components are set on one side of the two corresponding moving plates that are close to each other. The two sets of conveyor components work together to complete the automatic feeding and unloading of the advertising machine PCB.

[0008] Two sets of rotating components and two sets of conveying components are set on two corresponding moving plates to rotate the two sets of conveying components, thereby flipping the surface and facilitating inspection.

[0009] Two sets of clamping components are set on the corresponding rotating components to clamp and fix the advertising machine PCB when the rotating components rotate.

[0010] In one possible design, the conveying assembly includes a rotating plate, which is rotatably connected to one side of a moving plate via a rotating shaft. Two pulleys are symmetrically rotatably connected to one side of the rotating plate, and the same conveyor belt is driven onto the two pulleys. A second motor is fixedly mounted on the other side of the rotating plate, and the output end of the second motor passes through the rotating plate and is fixedly connected to one of the pulleys. The height of the conveyor belt is the same as that of the double-rail conveyor belts of the two double-rail conveyors, and the second motor drives the conveyor belt to rotate.

[0011] In one possible design, the rotating assembly includes a first motor, which is fixedly mounted on the side of the moving plate away from the rotating plate, and the output end of the first motor is fixedly connected to the rotating shaft.

[0012] In one possible design, the clamping assembly includes a pressure plate, a groove is provided on the top of the rotating plate, the pressure plate is located in the groove and slidably connected to the groove, an opening is provided on the side of the rotating plate near the conveyor belt, one side of the pressure plate passes through the opening and extends above the conveyor belt, and a cylinder is fixedly installed on the side of the rotating plate near the second motor, the output end of the cylinder being fixedly connected to the pressure plate.

[0013] In one possible design, two fixing blocks are symmetrically fixedly connected to the top of the base. Two guide rods are symmetrically arranged on the side of the two fixing blocks that are close to each other. Both guide rods pass through the two movable plates and are slidably connected to the two movable plates. A bidirectional threaded rod is rotatably connected between the two guide rods on the side of the two fixing blocks that are close to each other. The bidirectional threaded rods are threaded through the two movable plates, and the two movable plates are respectively located on the positive and negative thread sections of the bidirectional threaded rods.

[0014] In one possible design, the bottom of the base is fixedly equipped with a discharge bin at the discharge port to collect the PCBs of the advertising machine that fail the inspection.

[0015] In this application, firstly, by controlling the rotation of the bidirectional threaded rod, the two moving plates move towards each other, and the distance between the conveying components on the two moving plates is adjusted so that the advertising machine PCB can fall on the conveyor belts on the two conveying components and can pass through the two conveying components.

[0016] Next, two double-track conveyors are started. The feeding conveyor of the two double-track conveyors sends the advertising machine PCB to the conveyor belts on the two conveyor components. The second motor on the two conveyor components drives the corresponding conveyor belts to rotate, so that the advertising machine PCB is conveyed to the bottom of the detection device and then stops. Then the detection device detects the advertising machine PCB. After the front detection is completed, the pressure plate of the clamping component presses and fixes the advertising machine PCB under the action of the cylinder. Then, the first motor starts, driving the rotating shaft and the rotating plate to rotate, thereby realizing the rotation of the conveyor components and the advertising machine PCB.

[0017] After both sides have been inspected, the second motor on the conveying assembly starts again to convey the advertising machine PCB. At the same time, according to the inspection results, the qualified advertising machine PCB is conveyed to the unloading conveyor of the two double-rail conveyors. The unqualified PCB is conveyed to the unloading hopper for collection and processing by starting the first motor to drive the rotating shaft and rotating plate.

[0020] In this utility model, the advertising machine PCB solder joint double-sided inspection equipment realizes automatic flipping inspection and clamping fixation of the advertising machine PCB through the combined use of rotating components and clamping components, without manual operation, reducing the complexity of operation and the risk of damage to the PCB.

[0021] In this utility model, the advertising machine PCB solder joint double-sided inspection device realizes the synchronous movement of two moving plates through a bidirectional threaded rod and a guide rod, and adjusts the distance between the two moving plates to adapt to advertising machine PCB circuit boards of different widths, thereby improving the practicality of the device;

[0022] In this invention, the automatic feeding and unloading of advertising machine PCBs is achieved through the dual-track conveyor and conveying components, which greatly improves the detection efficiency. The combined use of the rotating component and the clamping component enables automatic flipping detection and clamping and fixing of the advertising machine PCBs during flipping, reducing the complexity of operation and the risk of damage to the PCBs.
