Description

Technical Field

[0001] This utility model relates to PCB board processing equipment, and more particularly to a PCB board linear conveying mechanism. Background Technology

[0002] Existing PCB printing equipment typically involves the linear conveying of PCB materials. However, during the conveying process, it is sometimes necessary for the materials on the upper and lower sides to have vertical turnover capabilities. Existing linear conveying mechanisms are limited by width and cannot rotate materials with the mechanism below. In addition, it is difficult to achieve width adaptation for PCB materials of different widths. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a linear conveying mechanism for PCB boards that can adapt to PCB boards of different widths and facilitate material turnover with the conveying mechanism below, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A PCB linear conveying mechanism includes a front support frame, a rear support frame, and two longitudinal conveying arms. The front ends of the two longitudinal conveying arms are slidably connected to the front support frame, and the rear ends of the two longitudinal conveying arms are slidably connected to the rear support frame. Both the front and rear support frames are provided with opening and closing drive components for driving the two longitudinal conveying arms to move closer or further apart. A linear conveying belt is provided on the longitudinal conveying arms, and a belt drive motor for driving the linear conveying belt is provided on the front support frame.

[0006] Preferably, the front support frame is provided with a front drive shaft, and two front drive wheels are sleeved on the front drive shaft. The front drive shaft is used to drive the front drive wheels to rotate, and the front drive wheels can slide left and right relative to the front drive shaft. The longitudinal conveying arm is provided with multiple conveyor pulleys. The linear conveyor belt passes around the multiple conveyor pulleys and the front drive shaft. The belt drive motor is used to drive the front drive shaft to rotate and drive the two linear conveyor belts on the left and right through the two front drive wheels.

[0007] Preferably, the belt drive motor and the front drive shaft are connected by a reduction gear assembly.

[0008] Preferably, the tensioning drive assembly includes a tensioning drive belt, and two longitudinal conveying arms are fixedly connected to the front and rear sides of the tensioning drive belt, respectively.

[0009] Preferably, the bottom of the longitudinal conveying arm is provided with a belt fixing seat, and the belt fixing seat is fixedly connected to the tensioning drive belt.

[0010] Preferably, the tensioning drive assembly includes a tensioning transmission belt, the front and rear ends of which are respectively connected to the tensioning drive belt on the front support frame and the rear support frame via pulley assemblies.

[0011] Preferably, the front support frame is provided with a tensioning drive motor, which is used to drive the tensioning transmission belt to rotate.

[0012] In the PCB board linear conveying mechanism disclosed in this utility model, each of the two longitudinal conveying arms is equipped with a linear conveying belt. The two parallel linear conveying belts can convey the PCB board in a straight line. For PCB boards of different widths, the opening and closing drive assembly can be used to drive the two longitudinal conveying arms to move closer or further apart, thereby adapting the size to the PCB board. In addition, when it is necessary to rotate the PCB board up and down, the lifting motion table in the preset loading conveying mechanism can move up and down between the two longitudinal conveying arms. After the lifting motion table lifts the PCB board, it separates the PCB board from the two longitudinal conveying arms. The opening and closing drive assembly drives the two longitudinal conveying arms to move further apart, so that the PCB board can descend with the lifting motion table to below the two longitudinal conveying arms, thereby realizing the up and down rotation function and improving the loading and unloading efficiency.

[0017] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0018] Combination Figures 1 to 4As shown, this embodiment proposes a PCB linear conveying mechanism, which includes a front support frame 61, a rear support frame 62, and two longitudinal conveying arms 60. The front ends of the two longitudinal conveying arms 60 are slidably connected to the front support frame 61, and the rear ends of the two longitudinal conveying arms 60 are slidably connected to the rear support frame 62. Both the front support frame 61 and the rear support frame 62 are provided with a tensioning drive assembly 63 for driving the two longitudinal conveying arms 60 to move closer or further apart. A linear conveying belt 64 is provided on the longitudinal conveying arms 60, and a belt drive motor 65 is provided on the front support frame 61 for driving the linear conveying belt 64 to rotate.

[0019] In the above structure, each of the two longitudinal conveying arms 60 is equipped with a linear conveyor belt 64. The two parallel linear conveyor belts 64 allow for the straight transport of PCB boards. For PCB boards of different widths, the opening and closing drive assembly 63 can be used to move the two longitudinal conveying arms 60 closer or further apart, thereby adapting them to the PCB board's size. Furthermore, when PCB boards need to be rotated vertically, please refer to [further details needed]. Figure 4 The lifting platform 23 in the preset feeding and conveying mechanism 2 can be raised and lowered between the two longitudinal conveying arms 60. After the lifting platform 23 lifts the PCB board, the PCB board is separated from the two longitudinal conveying arms 60. The opening and closing drive component 63 drives the two longitudinal conveying arms 60 to move away from each other, so that the PCB board can be lowered below the two longitudinal conveying arms 60 with the lifting platform 23, thereby realizing the up and down turnover function and improving the loading and unloading efficiency.

[0020] Please see Figure 4 The PCB board text inkjet printer includes a frame 1, on which a feeding conveyor 2, an inkjet printing mechanism 3, a flipping mechanism 4, and a discharging conveyor 5 are provided.

[0021] In a preferred embodiment, the front support frame 61 is provided with a front drive shaft 650, and two front drive wheels 651 are sleeved on the front drive shaft 650. The front drive shaft 650 is used to drive the front drive wheels 651 to rotate, and the front drive wheels 651 can slide left and right relative to the front drive shaft 650. The longitudinal conveying arm 60 is provided with multiple conveyor pulleys 600. The linear conveyor belt 64 passes around the multiple conveyor pulleys 600 and the front drive shaft 650. The belt drive motor 65 is used to drive the front drive shaft 650 to rotate, and drives the two linear conveyor belts 64 to rotate through the two front drive wheels 651.

[0022] The front drive shaft 650 can be a sliding rod with a square cross-section. Based on its square structure, it can drive the front drive wheel 651 to rotate synchronously and also allow the front drive wheel 651 to slide left and right relative to the front drive shaft 650, thereby achieving the dual functions of torque transmission and left and right sliding, ensuring that the two longitudinal conveying arms 60 have both the functions of linear conveying and spacing adjustment.

[0023] To achieve reliable driving, in this embodiment, the belt drive motor 65 and the front drive shaft 650 are connected by a reduction gear assembly 652.

[0024] In this embodiment, the tensioning and opening drive assembly 63 includes a tensioning and opening drive belt 630, and two longitudinal conveying arms 60 are fixedly connected to the front and rear sides of the tensioning and opening drive belt 630, respectively. In the above structure, when the tensioning and opening drive belt 630 is running, its two sides move synchronously and in opposite directions, simultaneously driving the two longitudinal conveying arms 60 to move closer or further apart.

[0025] Furthermore, the bottom of the longitudinal conveying arm 60 is provided with a belt fixing seat 601, which is fixedly connected to the tensioning drive belt 630.

[0026] In order to drive the tensioning and opening transmission belt 631 to operate, in this embodiment, the tensioning and opening drive assembly 63 includes a tensioning and opening transmission belt 631, and the front and rear ends of the tensioning and opening transmission belt 631 are respectively connected to the tensioning and opening drive belt 630 on the front support frame 61 and the rear support frame 62 through the pulley assembly 632.

[0027] In practical applications, the front support frame 61 is equipped with a tensioning drive motor 633, which is used to drive the tensioning transmission belt 631 to rotate.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
