Description

Technical Field

[0001] This utility model relates to the field of PCB inspection technology, specifically a PCB board inspection and feeding device. Background Technology

[0002] With the rapid development of the electronics industry, printed circuit boards (PCBs), as key core components of electronic products, directly affect product performance and market competitiveness. In the PCB inspection process, PCB materials are placed on a loading platform. Sensors on the loading platform detect the materials and transmit signals to a control console, which then coordinates the equipment operation. When a sensor detects material on the loading platform, it sends a material presence signal to the control console, which then controls the gripping device to pick up the PCB and place it in a designated position for subsequent inspection. The loading platform needs to handle various PCBs. Due to the diversity of PCB layouts and variations in cutout areas, the sensors on the loading platform must be adjusted accordingly during inspection, resulting in limited applicability. Traditional adjustment methods mainly fall into two categories: one is to manually adjust the sensor positions, and the other is to add multiple sensors to reduce the adjustment frequency.

[0003] However, traditional solutions have certain limitations. When manually adjusting the sensor position, screws are usually used for fixing, and each adjustment requires using an Allen wrench to loosen the screws, increasing the time cost of adjustment. While adding multiple sensors can avoid most of the adjustment operations to some extent, there are still gaps between the sensors, which may result in theoretical blind spots. In addition, adding more sensors also indirectly increases the cost of the equipment.

[0004] Therefore, there is an urgent need for a PCB board inspection and feeding device to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a PCB board inspection and feeding device to solve the problems of inconvenient adjustment of the feeding table sensor and high cost in the prior art, and to improve the applicability of the feeding device.

The connecting section is recessed and located between the fixing component and the pulling section.

[0016] As a preferred embodiment of a PCB board inspection and loading device, the sliding guide rail has multiple mounting slots arranged along the length of the sliding guide rail. A first fastener is inserted into the mounting slot and is threadedly connected to the loading table. The fixing strip has multiple fixing slots arranged along the length of the fixing strip.

There is a gap between the feeding plate and the baffle. The sensing end of the sensor is located at the gap. The lifting assembly is mounted on the mounting frame and is used to drive the feeding plate to move up and down. A sliding guide rail is connected to the feeding plate.

[0018] As a preferred embodiment of a PCB board inspection and loading device, the lifting assembly includes a driving component, a guide rail, and a moving plate.

This saves adjustment time and improves work efficiency. At the same time, this design avoids the increased cost caused by adding multiple sensors, as well as the theoretical blind zone problem caused by the gaps between the sensors. This reduces equipment costs and enhances the applicability and reliability of the feeding device. Attached Figure Description

[0033] This application discloses a PCB board inspection and feeding device.

[0034] Reference Figure 1 and Figure 2A PCB board inspection and loading device includes a loading platform 1, a sliding guide rail 2, a sensor 3, and a fixing strip 4. The sliding guide rail 2 is connected to the loading platform 1, and a sliding block 5 is slidably connected to the sliding guide rail 2. A mounting base 6 is connected to the side of the sliding block 5 away from the sliding guide rail 2. A mounting hole is opened through one side of the mounting base 6 and the side close to the sliding block 5. A fixing member 7 is inserted into the mounting hole. The sensor 3 is mounted on the mounting base 6. The sensor 3 is used to sense the material placed on the loading platform 1 and transmit the sensing signal to the control console. The length direction of the fixing strip 4 is parallel to the length direction of the sliding guide rail 2. The fixing strip 4 has fixing holes 41 that match the fixing members 7. The number of fixing holes 41 is multiple and they are distributed along the sliding direction of the sliding block 5.

[0035] When materials are placed on the loading platform 1, if sensor 3 successfully senses the materials, it transmits a material presence signal to the control console. The loading device can then proceed with subsequent processes in an orderly manner based on the material presence signal, ensuring the efficient progress of PCB board inspection. If sensor 3 does not sense the materials, its position needs to be adjusted. The operator removes the fixing part 7 from the mounting hole, disengaging it from the fixing hole 41 on the fixing strip 4. At this point, the fixing relationship between the mounting base 6 and the fixing strip 4 is released. The sliding block 5 is then manually moved, causing the sensor 3 to move along with the mounting base 6. Once the sliding block 5 has moved the sensor 3 to the appropriate position, the fixing part 7 is reinserted into the fixing hole 41 on the fixing strip 4 that matches the current position. This re-fixes the mounting base 6 and the fixing strip 4, thus completing the adjustment of the sensor 3's position. This allows the sensor 3 to normally sense the materials and transmit the sensing signal to the control console, ensuring the smooth progress of PCB board inspection.

[0036] Preferably, in order to further reduce the adjustment frequency of sensor 3, in this example, the number of sliding blocks 5 is two, and correspondingly, the number of sensors 3 is two.

[0037] Specifically, the loading platform 1 includes a mounting frame 11, a baffle 12, a loading plate 13, and a lifting assembly. The mounting frame 11 is fixedly connected to the frame of the testing equipment. The baffle 12 is fixedly connected to one side of the mounting frame 11. The loading plate 13 is located on the side of the baffle 12 away from the mounting frame 11. There is a gap between the loading plate 13 and the baffle 12. The mounting base 6 is L-shaped. The sensor 3 is fixed to the outer wall of one side of the adjacent sliding block 5 of the mounting base 6. The sensing end of the sensor 3 faces upward and is located in the gap between the loading plate 13 and the baffle 12. When the material is placed on the top of the loading plate 13, the sensing end of the sensor 3 senses the material placed on the loading plate 13 through the gap. The lifting assembly is assembled on the mounting frame 11 and is used to drive the loading plate 13 to move up and down. The sliding guide rail 2 is connected to the bottom wall of the loading plate 13.

[0038] The lifting assembly includes a drive component 14, a guide rail 15, and a moving plate 16. The drive component 14 is fixedly connected to the mounting frame 11 and is used to drive the moving plate 16 to move. The moving plate 16 is connected to the feeding plate 13. The guide rail 15 is fixedly connected to the inner wall of the mounting frame 11. The moving plate 16 is slidably connected to the guide rail 15. The guide rail 15 is vertically arranged, so that the drive component 14 drives the moving plate 16 to move in a directional manner along the guide rail 15, thereby improving the lifting stability of the feeding plate 13. Preferably, in this embodiment, the drive component 14 is a drive motor.

[0039] To further improve the lifting stability of the feeding plate 13, the lifting assembly also includes a lead screw 17, which is rotatably connected to the mounting bracket 11, fixedly connected to the output end of the drive component 14, and threadedly connected to the moving plate 16.

[0040] A support plate 18 is fixedly connected to the bottom wall of the feeding plate 13. The support plate 18 is fixedly connected to the moving plate 16. The support plate 18 is used to support the feeding plate 13. Specifically, the support plate 18 forms a right-angled triangle between the feeding plate 13 and the moving plate 16. The driving component 14 drives the feeding plate 13 to move up and down through the support plate 18.

[0041] When the material is placed on the top of the loading platform 1, the sensor 3 senses the material. If no material is sensed, the position of the sensor 3 needs to be adjusted until the sensor 3 senses the material. The control console receives the material signal and controls the drive unit 14 to start. The drive unit 14 drives the lead screw 17 to rotate, which drives the moving plate 16 to move in a direction along the guide rail 15. Then, through the support plate 18, the loading plate 13 is driven to rise until it rises to the designated position, so that the gripping device can grip the material.

[0042] To improve the position fixing efficiency of sensor 3, refer to Figure 2 and Figure 3 The fixing part 7 includes a fixing part and a limiting part 71. The fixing part is adapted to the fixing hole 41. One end of the fixing part is fixedly connected to one end of the limiting part 71. The cross-sectional area of ​​the fixing part is smaller than that of the limiting part 71. The cross-sectional area of ​​the limiting part 71 is larger than the opening area of ​​the mounting hole. The fixing part is inserted into the fixing hole 41 so that when the sensor 3 is fixed, the side of the limiting part 71 near the fixing part is in contact with the mounting base 6.

[0043] The fixing part is in the shape of a stepped frustum. Specifically, the fixing part includes a fixing section 72 and an installation section 73. Both the fixing section 72 and the installation section 73 are cylindrical. One end of the fixing section 72 is hemispherical. The end of the fixing section 72 away from the hemispherical shape is fixedly connected to one end of the installation section 73. The end of the installation section 73 away from the fixing section 72 is fixedly connected to the limiting part 71. The cross-sectional area of ​​the fixing section 72 is smaller than that of the installation section 73. The fixing section 72 is adapted to the fixing hole 41, and the installation section 73 is adapted to the installation hole. This facilitates the insertion of the fixing section 72 into the fixing hole 41 and the stable embedding of the installation section 73 into the installation hole, thereby improving the efficiency of installation and disassembly.

[0044] A puller is fixedly connected to the end of the limiting part 71 away from the mounting part. The puller is used to pull the fixing part 7 away from the fixing hole 41 and the mounting hole. Specifically, the puller includes a connecting section 74 and a pulling section 75. The connecting section 74 and the pulling section 75 are fixedly connected. The end of the connecting section 74 away from the pulling section 75 is fixedly connected to the limiting part 71. The connecting section 74 is recessed between the limiting part 71 and the pulling section 75. When the user needs to pull the fixing part 7 away, his / her fingers can be placed naturally in the recessed area to form a stable and comfortable grip posture, which makes it easy to exert force and smoothly pull the fixing part 7 away from the fixing hole 41 and the mounting hole.

[0045] To improve the accuracy of the insertion of the fixed section 72 into the fixed hole 41, the sliding guide 2 is provided with multiple mounting slots, which are distributed along the length of the sliding guide 2. A first fastener 21 is inserted into the mounting slot and is threaded to the feeding plate 13. The sliding guide 2 is fixedly connected to the bottom wall of the feeding plate 13 by the first fastener 21. The fixing strip 4 is provided with multiple fixing slots, which are distributed along the length of the fixing strip 4. A second fastener 42 is inserted into the fixing slot and is threaded to the feeding plate 13. The fixing strip 4 is fixedly connected to the bottom wall of the feeding plate 13 by the second fastener 42. Thus, the stability of the parallel arrangement of the sliding guide 2 and the fixing strip 4 is improved, thereby improving the accuracy of the insertion of the fixed section 72 into the fixed hole 41. Preferably, in this embodiment, both the first fastener 21 and the second fastener 42 are screws.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
