Description

Technical Field

[0001] This utility model relates to the technical field of PCB circuit board conveying equipment, and in particular to a conveying device for PCB circuit board testing. Background Technology

[0002] PCB inspection is a crucial step in ensuring its quality and reliability. Inspection can uncover defects in the design, manufacturing, and assembly processes of PCBs, thereby guaranteeing the performance of the final product. During PCB inspection, multiple PCBs need to be continuously fed into the inspection equipment for individual inspection.

[0003] The existing announcement number CN212798646U, entitled "A PCB Circuit Board Production Conveying Device," includes a frame and a conveyor belt. The conveyor belt is mounted on the surface of the frame, and a servo motor is installed on the left side of the bottom of the frame. A drying mechanism is installed on one side of the middle of the frame surface. The conveyor belt passes through the inner cavity of the drying mechanism. The drying mechanism consists of a heat-insulating protective cover, a top plate, a PTC heating element, a perforated cover, an H-shaped frame, and a fan. An anti-static mechanism is installed on the right side of the drying mechanism. The anti-static mechanism consists of a gantry frame, a U-shaped frame, a limiting tube, a spray nozzle, an ion fan, and a diverter tube. The servo motor drives the conveyor belt, allowing the conveyor belt to sequentially pass the PCB circuit board through the drying mechanism and the anti-static mechanism. This enables the drying mechanism and the anti-static mechanism to dry and eliminate static electricity from the PCB circuit board, improving the PCB circuit board transportation function.

[0004] However, during the transport of the PCB circuit boards, the conveyor belt is tensioned to drive the PCB circuit boards on the upper part for inspection and feeding. However, the PCB circuit boards lack a limiting structure. During transport, the PCB circuit boards are affected by the inertia of the operation, which causes the PCB circuit boards to slip. The displacement of the PCB circuit boards affects the effectiveness of the subsequent inspection and imaging of the PCB circuit boards. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a conveying device for PCB circuit board testing.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a conveying device for PCB circuit board testing, including a transport component and a clamping component. The transport component includes a transport frame, with conveying rollers symmetrically and horizontally rotatably connected to both sides of the top of the transport frame, and a transport belt tensioned and connected to the conveying rollers of the transport frame. A transport motor is horizontally fixed on the transport frame, and the output end of the transport motor is fixed to the conveying roller. The clamping components are symmetrically arranged on both sides of the outer wall of the transport belt, and multiple clamping components are arranged horizontally. The clamping components include a bracket, which is vertically fixed to the outer wall of the transport belt, and a sliding frame is horizontally fixed on the top surface of the bracket. A moving block is horizontally slidably assembled on the sliding frame, and a spring is horizontally fixed on one end of the moving block, and the other end of the spring is fixed to the inner wall of the sliding frame. A clamping strip is horizontally arranged on the top surface of the moving block.

[0007] As a preferred embodiment, a translation frame is horizontally fixed on the top surface of the moving block, and a slider is horizontally slidably assembled within the translation frame.

[0008] As a preferred option, one end of the clamping bar is fixedly connected to the slider.

[0009] As a preferred embodiment, a rotating base is vertically fixed on the top surface of the translation frame, and a screw is horizontally rotatably connected to the rotating base.

[0010] As a preferred embodiment, a screw hole plate is vertically fixed on the top surface of the slider, and the screw hole plate and the screw rod are connected by a threaded clamp.

[0011] As a preferred embodiment, the other end of the clamping strip is horizontally fixed with a clamping plate, and a soft pad is adhered to the clamping plate.

[0012] As a preferred option, testing equipment is vertically fixed on the top surface of the transport frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the PCB circuit board to be inspected is horizontally placed between the clamping parts on both sides of the conveyor belt. The PCB circuit board is pressed against by the ends of the clamping strips on the clamping parts. The clamping strips are acted upon by the spring deformation force, pushing the moving block to slide horizontally in the slide frame. Thus, the clamping parts on both sides of the conveyor belt relatively squeeze and clamp the PCB circuit board to maintain stability. Then, the conveyor motor is started to drive the conveyor roller to rotate, which drives the conveyor belt to run and drives the clamped PCB circuit boards to enter the inspection equipment in sequence for inspection. When the PCB circuit board is transported into the inspection equipment for inspection, the clamping parts ensure the stability of the PCB circuit board transportation, avoid the slippage of the PCB circuit board, and ensure the effectiveness of the subsequent inspection and imaging of the PCB circuit board.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0024] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0025] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0026] like Figures 1 to 5 As shown, a conveying device for PCB circuit board inspection includes a transport component 1 and a clamping component 2. The transport component 1 includes a transport frame 11, with conveyor rollers 12 symmetrically and horizontally rotatably connected to both sides of the top of the transport frame 11. A transport belt 14 is tensioned and connected to the conveyor rollers 12 of the transport frame 11. A transport motor 13 is horizontally fixed on the transport frame 11, and the output end of the transport motor 13 is fixed to the conveyor rollers 12. The clamping components 2 are symmetrically arranged on both sides of the outer wall of the transport belt 14, and multiple clamping components 2 are arranged horizontally. The clamping component 2 includes a bracket 21, which is vertically fixed to the outer wall of the transport belt 14. A sliding frame 22 is horizontally fixed on the top surface of the bracket 21. A moving block 23 is horizontally slidably assembled on the sliding frame 22. A spring 24 is horizontally fixed on one end of the moving block 23, and the other end of the spring 24 is fixed to the inner wall of the sliding frame 22. A horizontally fixed spring 24 is horizontally fixed on the top surface of the moving block 23. The conveyor frame 11 is equipped with clamping strips 27 and a testing device 3 is vertically fixed on its top surface. During use, the PCB circuit board to be tested is horizontally placed between the clamping members 2 on both sides of the conveyor belt 14. The PCB circuit board is pressed against by the ends of the clamping strips 27 on the clamping members 2. The clamping strips 27 are subjected to the deformation force of the spring 24, which pushes the moving block 23 to slide horizontally in the slide frame 22. Thus, the clamping members 2 on both sides of the conveyor belt 14 are used to squeeze and hold the PCB circuit board to maintain stability. Then, the conveyor motor 13 is started to drive the conveyor roller 12 to rotate, which drives the conveyor belt 14 to run and drives the clamped PCB circuit boards to enter the testing device 3 for testing in sequence. When the PCB circuit board is transported into the testing device 3 for testing, the clamping members 2 ensure the stability of the PCB circuit board transportation, avoid the PCB circuit board from slipping, and ensure the effectiveness of the subsequent PCB circuit board testing and imaging.

[0027] In one embodiment, such as Figure 5 As shown, a horizontally fixed translation frame 25 is mounted on the top surface of the movable block 23, and a slider 28 is horizontally slidably assembled in the translation frame 25. One end of the clamping strip 27 is fixedly connected to the slider 28. A vertically fixed rotating seat 251 is mounted on the top surface of the translation frame 25, and a screw 26 is horizontally rotatably connected in the rotating seat 251. A screw hole plate 281 is vertically fixed on the top surface of the slider 28, and the screw hole plate 281 and the screw 26 are threadedly connected to the clamping strip 27. A clamping plate 29 is horizontally fixed on the other end of the clamping strip 27, and a soft pad 291 is adhered to the clamping plate 29. In order to meet the clamping requirements of PCB circuit boards of different widths, rotating the screw 26 on the rotating seat 251 drives the screw hole plate 281 on the slider 28 to move the slider 28 horizontally in the translation frame 25, thereby adjusting the stability of the clamping strip 27 in pressing the PCB circuit board.

[0028] In this embodiment, the PCB circuit board to be tested is horizontally placed between the clamping members 2 on both sides of the conveyor belt 14. The PCB circuit board is pressed against the ends of the clamping strips 27 on the clamping members 2. The clamping strips 27 are subjected to the deformation force of the spring 24, which pushes the moving block 23 to slide horizontally in the slide frame 22. Thus, the clamping members 2 on both sides of the conveyor belt 14 are used to clamp the PCB circuit board relatively and keep it stable. Then, the conveyor motor 13 is started to drive the conveyor roller 12 to rotate, which drives the conveyor belt 14 to run and drives the clamped PCB circuit board to enter the testing equipment 3 in sequence for testing. When the PCB circuit board is transported into the testing equipment 3 for testing, the clamping members 2 ensure the stability of the PCB circuit board transportation.

[0029] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
