TECHNICAL FIELD

[0001] The present application relates to a track corner flat support rail changer, belonging to the technical field of mechanical equipment. BACKGROUND

[0002] Crystal oscillator, referred to as crystal, is a kind of miniature high-precision electronic components. At present, in the assembly and processing of crystal, the more efficient processing method is whole plate processing, that is, several hundred crystal monomers are arranged in matrix on a whole substrate, and then transported to the subsequent process for processing through double-belt conveying track. Because the processing of crystal has very high requirements on the environment, it is generally carried out in a dust-free workshop, so when the substrate is transported, any possible dust falling should be avoided. The traditional conveying belt is easy to produce debris and affect product quality, so in the whole plate processing technology, rubber band conveying belt is often used, that is, the whole substrate is conveyed only by being placed on the rubber band conveying belt on both sides. However, the rubber band conveying belt is taut on two rollers, and can only be transported in a straight line. When encountering a corner, it must be changed by track. The traditional track changing structure of mechanical arm is complex and high in cost. Therefore, it is an urgent technical problem for those skilled in the art to seek a low-cost track corner rail changer. SUMMARY

[0003] The present application provides a track corner flat support rail changer to overcome the defects of the prior art.

[0005] A track corner flat support rail changer, comprising a steering assembly and a flat support assembly, the steering assembly comprising a power mechanism, the power output shaft end of the power mechanism being hingedly connected with a steering yoke; the flat support assembly comprising a base, a supporting strut being mounted on the base through a cross shaft connector, a flat support plate being provided at the end of the supporting strut, the supporting strut being arranged in the steering yoke.

[0006] On the basis of the above technical scheme, the present application can also be improved as follows:

[0007] Further, the opening of the steering yoke is rotatably provided with a bearing, and the supporting strut is mounted in the bearing.

[0008] Further, the bearing comprises an inner ring and an outer ring, the outer ring of the bearing being mounted at the opening of the steering yoke through a pin shaft, the bearing being rotatable along the pin shaft, and the supporting strut being fixedly mounted in the inner ring of the bearing.

[0009] Further, the included angle between the central axis of the power output shaft and the plane where the steering yoke is located is 30°-60°.

[0010] Further, the cross shaft connector comprises a first connecting head and a second connecting head, the first connecting head is fixedly installed on the base, and the second connecting head is connected to the first connecting head, and the supporting support rod is fixedly installed on the second connecting head.

[0011] Further, the flat supporting plate is provided with a recess for supporting the crystal substrate.

[0012] Further, the flat supporting plate is provided with a positioning guide column.

[0013] Further, the top end of the positioning guide column is conical.

[0014] The present application has the advantages of:

[0015] The present application has the advantages of: The power mechanism drives the power output shaft to rotate, thereby driving the steering yoke to rotate, and the steering yoke drives the supporting rod to rotate, thereby driving the supporting rod to rotate around the base connecting point The dynamic supporting rod swings up and down and left and right around the base connecting point, thereby driving the supporting rod to drive the flat supporting plate to move along a virtual conical surface Move Since the first connecting head of the cross shaft connector is fixedly installed on the base, the second connecting head can only swing in the up-down and left-right directions relative to the first connecting head, and cannot rotate around the axis direction of the first connecting head, therefore, the flat supporting plate can always keep the direction of being roughly upward and move along the virtual conical surface, and the edges of the virtual conical surface pass through the first rubber band conveyor belt and the second rubber band conveyor belt respectively, and then the flat supporting plate can be lifted upward from the lower side of the first rubber band conveyor belt to support the product (the width of the product is greater than the width of the flat supporting plate) staying on the first rubber band conveyor belt, and the product is transported to the second rubber band conveyor belt, and then moves from the upper side to the lower side, so as to place the product on the second rubber band conveyor belt, and realize the track changing operation of the crystal substrate.

[0022] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0023] See Figures 1-5 A track corner flat-lift rail changer includes a steering assembly and a flat-lift assembly. The steering assembly includes a power mechanism 1, and a steering fork 4 is hinged to the end of the power output shaft 2 of the power mechanism 1. The angle between the central axis of the power output shaft 2 and the plane where the steering fork 4 is located is 30°-60°. The present invention does not limit the power mechanism 1, as long as it drives the rotation of the power output shaft 2. In this embodiment, the power mechanism 1 is preferably a motor. The end of the power output shaft 2 is connected to the fork support rod 3 by a pin. The steering fork 4 is installed at the end of the fork support rod 3. The steering fork 4 and the fork support rod 3 can be integrally formed or connected by bolts. The present invention does not limit them.

[0024] The flat support assembly includes a base 5, on which a support rod 7 is mounted via a cross-axis connector 6. The support rod 7 is located within the steering fork 4. A flat support plate 8 is provided at the end of the support rod 7. The flat support plate 8 has a groove with a flat bottom surface for supporting the crystal oscillator substrate 10. During track changing, the crystal oscillator substrate 10 is positioned on the flat support plate 8. The sidewalls of the groove provide a limiting effect on the crystal oscillator substrate 10, preventing it from falling. The groove supports the crystal oscillator substrate 10. The flat support plate 8 has a positioning guide post with a conical top. The crystal oscillator substrate 10 has corresponding positioning holes (see [reference]). Figures 2-4 ) or positioning slot (see Figure 5 The diameter of the positioning hole or the maximum width of the positioning groove is greater than the diameter of the positioning guide post, facilitating the insertion of the positioning guide post into the positioning hole or positioning groove. (See also...) Figures 2-5In the embodiment, the track for conveying the crystal oscillator substrate 10 on the crystal oscillator assembly production line is two parallel conveying belts 11, the width of the flat supporting plate 8 is less than the gap between the two conveying belts 11, so that the flat supporting plate 8 can pass through the gap between the two conveying belts 11, the width of the flat supporting plate 8 is less than the width of the crystal oscillator substrate 10, so that the crystal oscillator substrate 10 can be placed on the flat supporting plate 8; the bearing 9 is installed at the opening of the steering fork 4, the supporting branch 7 is installed in the bearing 9, and the bearing 9 is installed at the opening of the steering fork 4 through the pin shaft. The bearing 9 includes an inner ring and an outer ring, the outer ring of the bearing 9 is installed at the opening of the steering fork 4 through the pin shaft, the bearing 9 can rotate along the pin shaft, the supporting branch 7 is fixedly installed in the inner ring of the bearing 9, and the bearing 9 can rotate with the center axis being the line connecting the two pin shafts, so that the supporting branch 4 is prevented from being stuck during the continuous rotation of the supporting branch 7.

[0025] The cross shaft connector 6 includes a first connecting head 61 and a second connecting head 62, the first connecting head 61 is fixedly installed on the base, the second connecting head 62 is connected to the first connecting head 61, the second connecting head 62 can rotate in the up-down direction and the left-right direction around the connecting point, and the supporting branch is fixedly installed on the second connecting head 62.

[0026] The angle between the first track 12 and the second track 13 for track changing of the crystal oscillator substrate 10 is 90° in the embodiment, and the process of track changing of the crystal oscillator substrate 10 is as follows:

[0027] In the initial state, the flat supporting plate 8 is located below the gap between the two conveying belts 11 of the first track 12, after the conveying belts 11 transport the crystal substrate 10 above the flat supporting plate 8, the power mechanism 1 is started, the power mechanism 1 drives the power output shaft 2 to rotate, the power output shaft 2 drives the steering yoke 4 to rotate, the steering yoke 4 drives the supporting strut 7 to rotate upwards, so as to support the crystal substrate 10 on the flat supporting plate 8; the supporting strut 7 rotates around the connecting point of the first connecting head 61 and the second connecting head 62, that is, the complete motion track of the supporting strut 7 is a conical body with the connecting point of the first connecting head 61 and the second connecting head 62 as the apex, therefore, the flat supporting plate 8 can always move along the virtual conical surface in the roughly upward direction, and the edges of the virtual conical body pass through the first track 12 and the second track 13 respectively, after the supporting strut 7 moves to the highest point, the supporting strut 7 continues to rotate downwards around the connecting point of the first connecting head 61 and the second connecting head 62, until the supporting strut 7 drives the flat supporting plate 8 to move below the two conveying belts 11 of the second track 13, the crystal substrate 10 is placed on the second track 13, and the track switching of the crystal substrate 10 is completed, since the first connecting head 61 is fixed on the base 5, the rotation of the supporting strut 7 with the rotation of the steering yoke 4 is limited, but the supporting strut 7 rotates in the bearing 9, that is, the outer ring of the bearing 9 rotates with the steering yoke 4, and the inner ring of the bearing 9 rotates with the supporting strut 7, so as to ensure that the supporting surface of the flat supporting plate 8 for supporting the crystal substrate 10 always keeps roughly upward during the whole track switching process. After the track switching of one crystal substrate 10 is completed, the power output shaft 2 continues to rotate, drives the supporting strut 7 to continue to rotate below the second track 13 to below the first track 12, and continues to complete the track switching of the next crystal substrate 10, so as to realize the continuous track switching operation.

[0028] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
