[0031] like Figures 1-5 As shown, this utility model proposes a circuit board feeding device.

[0032] In one exemplary embodiment, the circuit board loading device includes:

[0033] Rack 1;

[0034] Conveying mechanism 2 is mounted on frame 1 and is used to drive the fixture to move along the conveying direction;

[0035] A positioning bracket is provided corresponding to the conveying mechanism 2. The positioning bracket includes a placement frame 8 and a lifting mechanism. The lifting mechanism is used to drive the placement frame 8 to rise or fall. The placement frame 8 is used for positioning fixtures.

[0036] A robotic arm 10 is mounted on a frame 1. The robotic arm 10 includes a gripper 1001, which is used to move a circuit board onto a fixture.

[0037] The testing mechanism 9 is mounted on the frame 1 and is used to test circuit boards.

[0038] In this embodiment, the circuit board is inspected before it arrives at the production line. If the inspected circuit board is free of problems, it is placed on the production line by the gripper 1001 on the robotic arm 10. If the inspected circuit board is defective, it is judged as NG and the defective circuit board is removed. This avoids defective circuit boards occupying the production line and reducing the production efficiency of the circuit board.

[0039] In this embodiment, the robotic arm 10 feeds the circuit board and moves it to the testing mechanism 9 for testing. The feeding, testing, and gripping of the circuit board can be completed without manual operation, which has a high degree of automation and reduces the labor intensity of the staff.

[0040] For example, in this embodiment, the frame 1 is provided with a feeding plate 11, which is arranged across the track 201. The feeding plate 11 is provided with multiple placement stations 12 for placing circuit boards. By using the feeding plate 11, when the inspection mechanism 9 determines that the circuit board is NG, the circuit board can be promptly picked up and placed to the placement station 12, thereby avoiding the problem of unqualified circuit boards entering the production line and occupying the production line. In this embodiment, there are multiple placement stations 12, which can place multiple unqualified circuit boards at the same time.

[0041] In an exemplary embodiment, the conveying mechanism 2 includes a track 201 and a belt 204. A drive motor 202 is provided on the track 201, and a drive wheel 203 is provided at the output end of the drive motor 202. The belt 204 is wound around the drive wheel 203, and the drive motor 202 is used to drive the belt 204 to reciprocate.

[0042] In this embodiment, through the set track 201 and belt 204, when the drive motor 202 is started, it will drive the drive wheel 203 to rotate, and the drive wheel 203 will drive the belt 204 to reciprocate, thereby moving the fixture placed on the belt 204 forward.

[0043] For example, in this embodiment, two tensioning pulleys are also provided on the track 201 to ensure that the belt 204 can move smoothly.

[0044] For example, in this embodiment, the number of tracks 201 is two.

[0045] For example, each of the two tracks 201 is provided with a limiting member 205, which corresponds to the positioning bracket and is located above the placement frame 8. When the lifting mechanism rises, the limiting member 205 limits the height of the fixture. In this embodiment, the limiting member 205 has a limiting part 206, which consists of two long rods extending towards the other track 201, with the ends of the long rods entering between the two tracks 201. When the lifting mechanism lifts the positioning bracket upwards, the fixture rises synchronously and disengages from the belt 204. A specific part of the fixture is blocked by the long rods of the limiting member 205 and cannot move upwards further, thus limiting the height of the fixture and ensuring that the circuit board can be stably placed on the positioning bracket. When the fixture needs to move with the belt 204, the lifting mechanism drives the fixture downwards, placing the fixture on the belt 204 so that it can move synchronously with the belt 204.

[0046] In an exemplary embodiment, the lifting mechanism includes a base 3 and a cylinder 7. The base 3 is mounted on the frame 1 and located between the rails 201. The cylinder 7 is mounted on the base 3. The extended end of the cylinder 7 passes through the base 3 and is connected to the placement frame 8. The base 3 is provided with a plurality of sleeves 4. A support rod 5 is slidably connected inside the sleeve 4. The free end of the support rod 5 is connected to the placement frame 8.

[0047] In this embodiment, the extension of the output end of the cylinder 7 will drive the positioning bracket to move upward. When the output end of the cylinder 7 retracts, it will drive the positioning bracket to move downward. The multiple support rods 5 can ensure the stability of the positioning bracket when moving up and down. When the positioning bracket rises, since the upper end of the support rod 5 is connected to the bottom of the positioning bracket, the support rod 5 will move upward with the positioning bracket and slide in the sleeve 4. The bottom of the support rod 5 is provided with a limiting nut 6, which will contact and limit the bottom of the sleeve 4 to prevent the support rod 5 from coming out of the sleeve 4.

[0048] For example, in this embodiment, there are four sleeves 4 and four support rods 5. During the rising and falling of the positioning bracket, the support rods 5 move synchronously.

[0049] For example, in this embodiment, the positioning bracket is provided with a plurality of positioning shafts 801, which are used to support and position the fixture.

[0050] In an exemplary embodiment, the detection mechanism 9 includes a drive frame 901 and a mounting frame 902. The mounting frame 902 is movably mounted on the drive frame 901, and a planar detector 903 and a three-dimensional detector 904 are provided on the mounting frame 902.

[0051] In this embodiment, the drive frame 901 has a driving function, which can drive the mounting frame 902 to move along the length direction of the drive frame 901. The planar detector 903 and the stereo detector 904 can perform planar and stereo detection on the target area of ​​the circuit board. The planar detector 903 and the stereo detector 904 are existing technologies and will not be described in detail here. In this embodiment, the detection method mainly adopts photography. After obtaining the photographic result, it is compared with the standard photo stored in the controller to obtain the detection result. The result is fed back to the controller to determine whether the front of the circuit board meets the requirements. If it meets the requirements, it is a qualified circuit board; if it does not meet the requirements, it is judged as NG (unqualified).

[0052] For example, in this embodiment, the drive frame 901 can be driven by a motor to rotate the lead screw, and the mounting frame 902 is mounted on the lead screw through a nut seat. When the motor rotates, it can drive the mounting frame 902 to move.

[0053] For example, the testing mechanism 9 also includes a testing frame 905, on which a testing tray 906 is provided. The testing tray 906 is used to fix the circuit board. In this embodiment, the testing tray 906 is mainly used to place the circuit board. After the circuit board is gripped onto the testing tray 906 by the gripper 1001 of the robotic arm 10, the planar detector 903 and the stereo detector 904 can move on the drive frame 901 to the corresponding position on the circuit board to take pictures and test the circuit board.

[0054] For example, the detection mechanism 9 also includes a camera module 907, which is mounted on the frame 1 and is used to detect the bottom of the circuit board. In this embodiment, after the planar detector 903 and the stereo detector 904 have detected the front of the circuit board, the bottom of the circuit board is detected by the camera module 907, and the detection is also completed by shooting and comparison.

[0055] It is worth noting that in this embodiment, the drive frame 901 can also adopt other driving methods, such as the movement of the mounting frame 902 driven by the travel of the hydraulic cylinder or the pneumatic cylinder 7.

[0056] In one exemplary embodiment, the device also includes a gripping mechanism 13, which includes a gripping part 1301 for gripping the fixture to the placement rack 8.

[0057] In this embodiment, the gripping mechanism 13 can move the fixture onto the positioning bracket for positioning and fixation. The gripping part 1301 of the gripping mechanism 13 can use a clamping member with a size that matches the fixture to grip the fixture, or it can use a robotic arm to grip the fixture.

[0058] Specific implementation steps:

[0059] The first step involves the robotic arm 10 picking up the circuit board from the loading rack and placing it onto the inspection tray 906. Once the sensor detects the circuit board's arrival, it controls the planar detector 903 and the three-dimensional detector 904 in the inspection mechanism 9 to move to their designated positions for inspection. If the inspection confirms the circuit board is correct, the gripper 1001 of the robotic arm 10 picks it up and places it onto the camera module 907 for bottom inspection. If the circuit board is determined to be a defective product, it is directly picked up and placed at the placement station 12 for the operator to retrieve. The second step involves the robotic arm 10 removing the circuit board from the inspection station after it has been determined to be a qualified product. Before the inspection begins, the base 3 of the fixture is placed on the belt 204 and corresponds to the placement frame 8 by the gripping mechanism 13, and is lifted by the lifting mechanism to prevent the base 3 of the fixture from being transported forward with the belt 204. After the circuit board is sensed to be placed on the base 3 of the fixture, the gripping mechanism 13 closes the cover plate of the fixture. At this time, the lifting mechanism controls the placement frame 8 to descend until the fixture contacts the belt 204. Then the belt 204 can drive the fixture and the circuit board forward to the next process station.

[0060] In summary, this utility model inspects the circuit boards before they arrive at the production line. If the inspected circuit boards are free of problems, they are placed on the production line by the gripper 1001 on the robotic arm 10. If problems are found, they are deemed NG and removed. This avoids unqualified circuit boards occupying the production line and reducing the production efficiency of the circuit boards.

[0061] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
