Description

Technical Field

[0001] This utility model belongs to the field of surface mount technology (SMT) inspection technology, specifically an SMT surface mount inspection device. Background Technology

[0002] SMT (Surface Mount Technology) is a circuit assembly technology that mounts leadless or short-lead surface mount components onto the surface of a printed circuit board or other substrates, and then assembles them by reflow soldering or dip soldering, achieving high-density circuit assembly.

[0003] In current technology, SMT assembly generally requires the use of an inspection device. A conveyor mechanism moves the PCB board to the inspection mechanism, which then checks whether the SMT assembly is qualified. However, existing conveyor mechanisms typically have a PCB board template to hold the PCB board within the template. After inspection, the PCB board needs to be removed from the template, which can easily damage the PCB board or components, affecting product quality. Therefore, improvements are needed. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an SMT (Surface Mount Technology) chip inspection device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an SMT chip inspection device, including an inspection table, a conveying mechanism inside the inspection table, and an inspection mechanism located above the conveying mechanism on the top of the inspection table;

[0006] The conveying mechanism includes a disc, the bottom of which is movably connected to the top of the testing platform. A material trough is provided on the top of the disc, and a mounting frame is provided on the bottom of the disc. A movable plate is movably connected to the inner cavity of the mounting frame. A top block located in the material trough is provided on the top of the movable plate, and a pressure block located outside the mounting frame is provided on the bottom of the movable plate. A connecting frame is provided at the bottom of the testing platform, and an inclined block located below the pressure block is provided on the inner wall of the connecting frame.

[0007] Preferably, the conveying mechanism includes a drive motor, the inner side of which is connected to the bottom of the detection platform, and the output shaft of the drive motor is connected to the bottom of the disc.

[0008] Preferably, the mounting bracket is sleeved inside the connecting bracket cavity, and the inner wall of the connecting bracket is movably connected to the outer surface of the mounting bracket.

[0009] Preferably, four mounting brackets are provided, and the four mounting brackets are evenly distributed on the disc.

[0010] Preferably, the inner wall of the mounting frame is provided with a limiting post, the bottom of the limiting post is connected to the bottom of the disc, and the outer surface of the limiting post is movably connected to the inner wall of the movable plate.

[0011] Preferably, a spring is provided on the top of the movable plate, and the other end of the spring is connected to the bottom of the disc.

[0012] Preferably, the top block is provided in four sets, and each of the four sets of top blocks is provided with a rubber pad on its top.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model is equipped with a disc and a top block. When the drive motor is started, the disc rotates as a whole. When the disc transfers the PCB board after inspection to the top of the inclined block, the pressure block squeezes and moves the pressure block, movable plate and top block upward. Then the rubber pad on the top of the top block pushes the PCB board out of the material groove, which makes it easier for the operator to pick up the PCB board and avoids damage during the picking process.

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1 to 6 As shown, this is the first embodiment of the utility model, which provides an SMT chip inspection device, including an inspection table 1, a conveying mechanism 2 inside the inspection table 1, and an inspection mechanism 3 located above the conveying mechanism 2 on the top of the inspection table 1.

[0025] The conveying mechanism 2 includes a disc 202, the bottom of which is movably connected to the top of the testing platform 1. A material trough 203 is provided on the top of the disc 202, and a mounting frame 204 is provided on the bottom of the disc 202. A movable plate 206 is movably connected to the inner cavity of the mounting frame 204. A top block 207 located inside the material trough 203 is provided on the top of the movable plate 206, and a pressure block 208 located outside the mounting frame 204 is provided on the bottom of the movable plate 206. A connecting frame 210 is provided on the bottom of the testing platform 1, and an inclined block 211 located below the pressure block 208 is provided on the inner wall of the connecting frame 210.

[0026] When the disc 202 rotates, it moves the PCB board placed in the material tray 203 after SMT assembly, moving it to the area below the inspection mechanism 3 for quality inspection. After inspection, the disc 202 drives the PCB board to reset. At this time, the pressure block 208 at the bottom of the disc 202 is pressed against the inclined block 211, causing the pressure block 208 to move upward. The pressure block 208 then drives the movable plate 206 and the spring 209 to move upward. The spring 209 pushes the PCB board placed in the material tray 203 out, making it easy to remove the PCB board from the material tray 203 and preventing damage. This provides convenience for operators.

[0027] Example 2

[0028] like Figure 2 and Figure 3 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the conveying mechanism 2 includes a drive motor 201, the inner side of the drive motor 201 is connected to the bottom of the detection table 1, and the output shaft of the drive motor 201 is connected to the bottom of the disc 202.

[0029] By starting the drive motor 201, the disc 202 is rotated as a whole, which in turn moves the components in the inner cavity of the mounting bracket 204, causing the pressure block 208 to contact and press against the inclined block 211. At the same time, the PCB board placed in the material trough 203 is moved to the bottom of the detection mechanism 3 for chip placement detection.

[0030] The mounting bracket 204 is sleeved in the inner cavity of the connecting bracket 210, and the inner wall of the connecting bracket 210 is movably connected to the outer surface of the mounting bracket 204.

[0031] When the disc 202 drives the mounting frame 204 to rotate as a whole via the drive motor 201, the mounting frame 204 rotates inside the connecting frame 210, causing it to drive the pressure block 208 and the inclined block 211 to squeeze, thereby pushing out the PCB board placed inside the mounting frame 204 through the top block 207, making it convenient for operators to pick up the PCB board.

[0032] There are four mounting brackets 204, which are evenly distributed on the disc 202.

[0033] Four mounting brackets 204 are used for loading, transferring, inspecting and unloading PCB boards respectively, so that the PCB boards in different positions have clear division of labor, thereby cyclically inspecting the SMT assembly of the PCB boards and improving work efficiency.

[0034] Among them, the inner wall of the mounting bracket 204 is provided with a limiting post 205, the bottom of the limiting post 205 is connected to the bottom of the disc 202, and the outer surface of the limiting post 205 is movably connected to the inner wall of the movable plate 206.

[0035] When the pressure block 208 is squeezed by the inclined block 211, it moves upward. The pressure block 208 drives the movable plate 206 to move on the outer surface of the limiting post 205. The limiting post 205 limits the movable plate 206 to prevent it from shifting position during movement.

[0036] Among them, the top of the movable plate 206 is provided with a spring 209, and the other end of the spring 209 is connected to the bottom of the disc 202;

[0037] At this time, since the spring 209 is in a compressed state, it will apply downward pressure to the movable plate 206, which will facilitate the reset of the pressure block 208 and the top block 207, so that they can be tested and used again.

[0038] Among them, the top block 207 is provided in four sets, and the top of each of the four sets of top blocks 207 is provided with a rubber pad;

[0039] The rubber pad on top prevents the top block 207 from damaging the PCB board when it is ejected, and also cushions the component from damage.

[0040] Working principle and usage process of this utility model:

[0041] First, when the operator is performing SMT placement inspection on the PCB board, the PCB board is placed in the material tray 203. Then, the drive motor 201 is started, which drives the disc 202 and the mounting bracket 204 to rotate as a whole, thereby transferring the material tray 203 containing the PCB board to the bottom of the inspection mechanism 3 for inspection. At the same time, a PCB board is placed in the material tray 203 every 90 degrees. After the PCB board in the material tray 203 has been inspected, the disc 202 is rotated again to transfer the uninspected PCB board to the bottom of the inspection mechanism 3. At the same time, the inspected PCB board will rotate to the bottom of the inclined block 211. The inclined surface on the outside of the inclined block 211 will squeeze and drive the pressure block 208, the movable plate 206 and the top block 207 to move upward. The rubber pad on the top of the top block 207 will push the inspected PCB board out, which makes it easier for the operator to pick up the material. This avoids damage to the electronic components and the board material when manually picking up the material, and brings convenience to the operator.
