Summary of the invention
[0006] Purpose of the invention:
[0007] The invention provides an electronic component transfer machine with a conveying track capable of changing position, changing interval and changing position height.
[0008] Technical solution:
[0009] The electronic component transfer machine of the present invention has a horizontally arranged X-axis track, a Y-axis track, and an inclined track (an inclined track A, an inclined track B, or two inclined tracks) arranged obliquely.
[0010] The Y-axis track has two monorails arranged in parallel, the X-axis track has three monorails arranged in parallel, and the oblique track has two monorails arranged in parallel.
[0011] The three single rails of the X-axis track can move forward and backward on the Y-axis track, so that they can change their positions on the Y-axis track.
[0012] The distance between the two outer monorails (monorail A and monorail C) of the X-axis track is constant, and the middle movable monorail (monorail B) can move left and right, so that the distance between monorail A and monorail B can be changed, which is convenient for loading and transferring electronic components of different widths (rectangular components, devices, frames, etc.). The movable monorail is fixedly connected with a nut (the nut hole axis is perpendicular to the movable monorail), and a screw is threaded in the nut. The head end of the screw passes through an X-axis monorail A and is connected to the drive motor, and the tail end of the screw is movably connected to another X-axis monorail C. When the drive motor drives the screw to rotate, the nut drives the movable monorail B to move left and right.
[0013] On the side of the X-axis monorail A opposite to the movable monorail B, a synchronous belt assembly driven by a stepper motor (a synchronous belt and two synchronous wheels that drive the synchronous belt to move, one of which is connected to a driving motor) is provided. The electronic devices are supported and transported forward above the synchronous belt.
[0014] The inclined track A or the inclined track B is a track that relies on the gravity of the electronic devices to slide down.
[0015] The inclined track can be connected to the X-axis track, and the distance between the monorail A and the monorail B can be adjusted to be the same as the distance between the two monorails of the inclined track. The inclined track can transfer the electronic devices transported thereon from a high place to the synchronous belt of the X-axis track through the inclined track A, or transfer from the synchronous belt of the X-axis track to the inclined track B and transport them to a low place.
[0016] The lower end of the inclined track A (the part connected to the X-axis track) has a movable plate A, which can rotate around the rotation axis A, and the rotation axis A is connected to the front end of the synchronous belt (so that the electronic device can be transported there without getting stuck). A spring A is connected to the lower side of the movable plate A; when the electronic device passes through the movable plate A, the spring A is compressed by the weight of the electronic device, so that the movable plate A rotates around the rotation axis A, changing from an upward inclined direction to a horizontal direction, so that the electronic device is automatically transferred from the inclined track A to the synchronous belt of the horizontal X-axis track. After the electronic device passes, the compressed spring A relies on its own rebound to drive the movable plate A to return to the inclined state to receive the subsequent electronic devices that are transported by sliding down.
[0017] The rear end of the synchronous belt (the part connected to the oblique track B) has a movable plate B, which can rotate around the rotating shaft B, and the rotating shaft B is connected to the rear end of the synchronous belt (so that the electronic device can be transported there without getting stuck). A spring B is connected to the lower side of the movable plate B; when the electronic device passes through the movable plate B, the spring B is compressed by the weight of the electronic device, so that the movable plate B rotates around the rotating shaft B, changing from horizontal to downward oblique, so that when the electronic device passes through the movable plate B from the horizontal synchronous belt, the movable plate B is rotated by the weight of the electronic device itself and transferred to the oblique track B. After the electronic device passes, the compressed spring B relies on its own rebound to drive the movable plate B to return to the horizontal state to receive the subsequent electronic devices transported horizontally.
[0018] The elastic force generated by the compression of the spring A and the spring B is smaller than the component of the sum of the gravity of the electronic device and the movable plate in the direction perpendicular to the inclined plane, and larger than the component of the gravity of the movable plate in the direction perpendicular to the inclined plane, so that the movable plate can be rotated open or closed according to design requirements.
[0019] Beneficial effects:
[0020] The invention has multiple functions, can transport electronic components to different positions, can transport electronic components of different widths, and can automatically change the position height of electronic components. Among them, the adjustment of position and width is realized by motorization, and the height adjustment is completed automatically. The invention has the advantages of fast moving speed, high precision, low energy consumption, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The three monorails (monorail A2, monorail B3, monorail C4) of the X-axis track 1 can move forward and backward on the Y-axis track 5, so that they can change their positions on the Y-axis track 5.
[0029] The distance between the single rail A and the single rail C4 of the X-axis track 1 is constant, and the middle single rail B3 can move left and right, so that the distance between the single rail A2 and the single rail B3 can be changed.

[0031] Embodiment 2:
[0032] The electronic component transfer machine in the first embodiment also has the following features: Figure 4The inclined track A13 and the inclined track B17 shown; the inclined tracks 13 and 17 can be interconnected with the X-axis track 1, and the electronic devices 14 transported thereon can be moved from a high place through the track A13 to the X-axis track 1 by their own gravity, or transported to the low X-axis track 1 through the inclined track B17.
[0033] The lower end of the inclined track A13 is provided with a movable plate A16, and a spring A21 is connected to the lower side of the movable plate A16; when the electronic device 14 passes through the movable plate A16, the spring A21 is compressed by relying on its own weight, so that the movable plate A16 rotates around the rotation axis A20, changing from an upward inclined direction to a horizontal direction, so that the electronic device 14 is transferred from the inclined track A13 to the horizontal X-axis track 1.
[0034] The rear end of the synchronous belt 7 has a movable plate B19, and a spring B23 is connected to the lower side of the movable plate B19; when the electronic device 14 passes through the movable plate B19, relying on its own weight, the spring B23 is compressed, so that the movable plate B19 rotates around the rotation axis B22, changing from horizontal to downward inclined, so that the electronic device 14 is transferred from the horizontal synchronous belt 7 to the inclined track B17 through the movable plate B19.
[0035] The elastic force generated by the compression of the spring A21 or the spring B23 corresponds to a component that is smaller than the sum of the gravity of the electronic device 14 and the movable plate A16 or the movable plate B19 in the direction perpendicular to the inclined surface, and is greater than the component of the gravity of the movable plate A16 or the movable plate B19 in the direction perpendicular to the inclined surface; so that the springs 21 and 23 can be compressed by the electronic device 14 respectively, and when the electronic device is removed, the movable plate A16 or the movable plate B19 can rotate and return to the inclined state by itself.
