Description

Technical Field

[0001] This utility model relates to the field of transfer device technology, and in particular to a ceramic circuit board transfer device. Background Technology

[0002] Ceramic circuit boards (CPCBs) are widely used in the manufacture of high-power, high-frequency electronic devices due to their excellent electrical properties, high thermal conductivity, and good mechanical strength. In the transfer process of CPCBs, precise positioning and stable transfer operation are crucial for ensuring product quality and production efficiency. Current technologies typically use multi-axis robotic arms to transfer CPCBs after they have been unloaded from the PCB depaneling machine. However, existing PCB depaneling machines are prone to positional misalignment during the unloading process, which affects the accuracy of the transfer. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a ceramic circuit board transfer device.

[0004] The technical solution is as follows: A ceramic circuit board transfer device includes a base frame, a material preparation rack on one side of the top of the base frame, a multi-axis robotic arm on the other side of the top of the base frame, a suction nozzle installed at the end of the multi-axis robotic arm, a feeding mechanism on the material preparation rack for feeding ceramic circuit boards from top to bottom, an electric slide rail in the middle of the top of the base frame, one end of the electric slide rail extending to the bottom of the material preparation rack, a positioning mechanism on the top of the base frame and at the other end of the electric slide rail, a slide table connected to the output end of the electric slide rail for receiving ceramic circuit boards from the material preparation rack and transferring the received ceramic circuit boards to the positioning mechanism.

[0005] As a further preferred embodiment, the feeding mechanism includes two vertically arranged belt assemblies. The two pulleys of the belt assemblies are rotatably connected to the material preparation rack. Two motors are installed on the material preparation rack. The two motors are used to drive the pulleys of the two belt assemblies to rotate. Multiple support bars are arranged at intervals along the length direction on the flat belt of the belt assembly. The support bars between the two belt assemblies and on the same horizontal plane are used to horizontally support the ceramic circuit board.

[0006] As a further preferred embodiment, the positioning mechanism includes two limiting plates 1 parallel to the axis of the electric slide rail, a limiting plate 2 perpendicular to the axis of the electric slide rail, and two limiting plates 3. The two limiting plates 3 are respectively disposed on the two limiting plates 1 at the ends away from the limiting plates 2, and the limiting plates 3 are parallel to the limiting plates 2. The two limiting plates 1 can move closer to or further away from each other, and the limiting plates 3 can move closer to or further away from the limiting plates 1.

[0007] As a further preferred embodiment, a bidirectional lead screw is rotatably connected to the base frame, and a second motor for driving the bidirectional lead screw to rotate is installed on the base frame. Each of the two different threaded sections of the bidirectional lead screw is threadedly connected to a first connecting plate. Both first connecting plates are slidably connected to the base frame, and the two first connecting plates are respectively fixedly connected to two first limiting plates. The second limiting plate is fixedly connected to the base frame through the second connecting plate.

[0008] As a further preferred option, electric push rods are installed on the opposite sides of the two limiting plates. The output ends of the electric push rods are parallel to the axis of the electric slide rail and face the second limiting plate. Guide rods are slidably connected to the opposite sides of the two limiting plates. One end of the guide rod is fixedly connected to the third limiting plate, and the other end of the guide rod is fixedly connected to the output end of the electric push rod.

The inner bottom surfaces of limiting plate one and limiting plate two can work together to support the ceramic circuit board, and the inner bottom surfaces of limiting plate one and limiting plate two are flush with the top surface of the slide table.

[0010] Compared with the prior art, the present invention has the following advantages: After the ceramic circuit board is received by the slide table and transferred to the positioning mechanism, the present invention first achieves preliminary positioning through the second limiting plate, then drives the two first limiting plates to move closer to each other with the help of the bidirectional lead screw to limit the two sides of the ceramic circuit board, and finally drives the third limiting plate to move towards the first limiting plate through the electric push rod to achieve multi-directional precise positioning of the ceramic circuit board, thereby improving the accuracy of ceramic circuit board transfer.

[0017] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0018] An embodiment provides a ceramic circuit board transfer device, such as Figures 1-5 As shown, the system includes a base frame 1, a material preparation rack 2 on one side of the top of the base frame 1, and a multi-axis robotic arm 3 on the other side of the top of the base frame 1. The end of the multi-axis robotic arm 3 is equipped with a suction nozzle. A feeding mechanism 4 is provided on the material preparation rack 2. The feeding mechanism 4 is used to feed ceramic circuit boards from top to bottom. An electric slide rail 5 is provided in the middle of the top of the base frame 1. One end of the electric slide rail 5 extends to the bottom of the material preparation rack 2. A positioning mechanism 7 is provided on the top of the base frame 1 and at the other end of the electric slide rail 5. A slide table 6 is connected to the output end of the electric slide rail 5. The slide table 6 is used to receive the ceramic circuit boards from the material preparation rack 2 and transfer the received ceramic circuit boards to the positioning mechanism 7. The distances from the four sides of the slide table 6 to the center of the ceramic circuit board to be transferred are all less than the distances from the four sides of the ceramic circuit board to its center.

[0019] In this embodiment, the feeding mechanism 4 includes two vertically arranged belt assemblies 41. The two pulleys of the belt assemblies 41 are rotatably connected to the material preparation rack 2. The material preparation rack 2 is equipped with two motors 42, which are used to drive the pulleys of the two belt assemblies 41 to rotate. Multiple support bars 43 are arranged at intervals along the length direction on the flat belt of the belt assembly 41. The ceramic circuit board is horizontally supported on the support bars 43 on the two belt assemblies 41 that are close to each other on one side and on the same horizontal plane. The two belt assemblies 41 rotate synchronously in opposite directions. Specifically, the rotation of the two belt assemblies 41 can cause the support bars 43 supporting the ceramic circuit board to move from top to bottom.

[0020] In this embodiment, the positioning mechanism 7 includes two limiting plates 71 parallel to the axis of the electric slide rail 5, a limiting plate 72 perpendicular to the axis of the electric slide rail 5, and two limiting plates 73. The two limiting plates 73 are respectively disposed on the two limiting plates 71 at the ends away from the limiting plate 72, and the limiting plates 73 are parallel to the limiting plates 72. The two limiting plates 71 can move closer to or further away from each other, and the limiting plates 73 can move closer to or further away from the limiting plates 71. The limiting plates 71 and 72 are both L-shaped structures. The inner bottom surfaces of the limiting plates 71 and 72 can cooperate to support the ceramic circuit board, and the inner bottom surfaces of the limiting plates 71 and 72 are flush with the top surface of the slide table 6.

[0021] In this embodiment, a bidirectional lead screw 74 is rotatably connected to the base frame 1, and a second motor 75 for driving the bidirectional lead screw 74 to rotate is installed on the base frame 1. Two different threaded sections of the bidirectional lead screw 74 are threadedly connected to connecting plates 81. Both connecting plates 81 are slidably connected to the base frame 1, and the two connecting plates are respectively fixed to two limiting plates 71. The second limiting plate 72 is fixed to the base frame 1 through the connecting plate 82.

[0022] In this embodiment, electric push rods 76 are installed on the sides of the two limiting plates 71 that are far apart from each other. The output end of the electric push rod 76 is parallel to the axis of the electric slide rail 5 and faces the limiting plate 72. Guide rods 77 are slidably connected to the sides of the two limiting plates 71 that are far apart from each other. One end of the guide rod 77 is fixedly connected to the limiting plate 73, and the other end of the guide rod 77 is fixedly connected to the output end of the electric push rod 76.

[0023] Working principle: Initially, ceramic circuit boards are placed on support bars 43 on the same horizontal plane between the two belt assemblies 41. The slide table 6 is located below the bottom ceramic circuit board, and the distance between the two connecting plates 81 is at its maximum to ensure that the limiting plate 73 does not obstruct the movement path of the ceramic circuit board. In use, the two motors 42 drive the corresponding belt assemblies 41 to rotate synchronously in opposite directions, causing the support bars 43 on the flat belts to move the ceramic circuit boards downwards until the bottom ceramic circuit board is supported by the slide table 6. Then, the electric slide rail 5 drives the slide table 6 to move towards the multi-axis robotic arm 3 until the side of the ceramic circuit board supported by the slide table 6 abuts against the limiting plate 72, and the ceramic circuit board is supported by the inner bottom surface of the limiting plate 72, achieving the initial positioning of the ceramic circuit board. Then, the motor 75 drives the bidirectional lead screw 74 to rotate, causing the two connecting plates 81 to move along the bidirectional lead screw 74. The screw 74 moves axially towards each other, causing the two limiting plates 71 to move closer together until they abut against the sides of the ceramic circuit board. The ceramic circuit board is supported by the inner bottom surface of the limiting plates 71. Then, the output ends of the two electric push rods 76 extend, causing the corresponding guide rods 77 to move the limiting plate 73 towards the limiting plate 71 until both limiting plates 73 abut against one side of the ceramic circuit board. At this point, the ceramic limiting plates are jointly limited by the limiting plates 71, 72, and 73, achieving precise positioning. Subsequently, the electric slide rail 5 drives the slide table 6 to move and reset to the side of the material rack 2. At this point, the ceramic circuit board is supported by the limiting plates 71 and 72 and is in a stable positioning state. Afterward, the multi-axis robotic arm 3 drives the suction nozzle at its end to pick up the ceramic circuit board and performs a transfer operation to move the ceramic circuit board to the designated position.

[0024] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
