Description

Technical Field

[0001] The utility model belongs to the field of silicon crystal plate processing, in particular to a silicon crystal plate reversing conveying platform. Background Art

[0002] The main components of silicon crystal panels vary by type, but typically include diatomaceous earth, modified calcium sulfate dihydrate crystals, and other ingredients. For negative ion silicon crystal panels, their main ingredients also include natural minerals that produce negative ions. Therefore, silicon crystal panels are widely used in the construction industry. After being produced and formed, the panels are unloaded onto a conveyor line for transport. The conveyor line consists of a pair of front and rear conveyor tables, with a reversing conveyor table located between them. Each conveyor table typically has a pair of trimming assemblies. When the silicon crystal panel is on the front conveyor table and passes through the trimming assemblies, the trimming assemblies perform the initial trimming on both sides of the panel. The panel is then transferred to the reversing conveyor table, where it is rotated 90 degrees to adjust its direction before being transferred to the rear conveyor table. The rear conveyor table transports the panel to the next workstation. As the panel passes through the trimming assemblies on the rear conveyor table, the trimming assemblies perform a second trimming on the remaining two sides of the panel, completing the trimming of all four sides.

[0003] When the existing reversing conveyor is reversing and adjusting the direction, it is common to directly drive the reversing conveyor to rotate by a rotary motor to complete the reversing action. Although this can also complete the reversing action well, the entire reversing process is not very stable. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a silicon wafer reversing conveying platform, aiming to solve the problem that the existing silicon wafer reversing conveying platform is not stable during the reversing process.

[0005] The utility model adopts the following technical solutions:

[0006] The reversing conveying platform includes a machine platform, a belt conveyor is provided on the top surface of the machine platform, a ring-shaped lifting platform is provided on the machine platform, the machine platform is located inside the lifting platform, a rotating frame is provided on the top surface of the lifting platform for rotation, and a reversing mechanism for driving the rotating frame to rotate is provided on the lifting platform, the reversing mechanism includes a fixed frame rotatably mounted on the top of the lifting platform, a pressure wheel is rotatably provided on the inner side of the rotating frame on the fixed frame, a pressure cylinder is also provided on the lifting platform, the driving shaft of the pressure cylinder is rotatably connected to the fixed frame, a reducer is fixed to the bottom of the lifting platform, the output shaft of the reducer is rotatably connected to the pressure wheel through a first universal joint coupling, and a driving motor is also provided on the machine platform, and the driving shaft of the driving motor is rotatably connected to the input shaft of the reducer through a second universal joint coupling.

[0007] Furthermore, a circle of support wheels is rotatably provided on the top surface of the lifting platform, and the support wheels support the rotating frame. A limiting wheel is also rotatably provided on the top surface of the lifting platform between adjacent support wheels, and the limiting wheel is located on the outside of the rotating frame.

[0008] Furthermore, a connecting arm is provided at the bottom of the lifting platform, and the lifting platform is slidably installed on the machine platform through the connecting arm. A lifting cylinder is provided at the bottom of the machine platform, and a driving shaft of the lifting cylinder is connected to the connecting arm.

[0009] Furthermore, a limit column and a pair of support columns are provided at the upper and lower positions on both sides of the machine, facing the connecting arm respectively.

[0010] Furthermore, a circle of support frames is provided on the top surface of the rotating frame.

[0011] The beneficial effect of the present invention is that after the silicon crystal plate is conveyed onto the belt conveyor, the lifting platform moves upward until the rotating frame lifts up the silicon crystal plate, and the silicon crystal plate is a short distance away from the belt conveyor. Then the drive motor starts to work, and the pressure wheel drives the rotating frame to rotate to 90 degrees under the drive of the drive motor. At this time, the silicon crystal plate completes the reversing action, and then the lifting platform moves downward until the silicon crystal plate falls back onto the belt conveyor. Finally, the belt conveyor conveys the silicon crystal plate to the rear conveying platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0017] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0018] Combine Figure 1-3As shown, the reversing conveying platform includes a machine platform 1, a belt conveyor 2 is provided on the top surface of the machine platform 1, a ring-shaped lifting platform 3 is provided on the machine platform 1, the machine platform 1 is located in the lifting platform 3, and a rotating frame 4 is rotatably provided on the top surface of the lifting platform 3, and a reversing mechanism for driving the rotating frame 4 to rotate is provided on the lifting platform 3, and the reversing mechanism includes a fixed frame 5 rotatably mounted on the top of the lifting platform 3, and a pressure wheel 7 is rotatably provided on the inner side of the rotating frame 4 on the fixed frame 5, and a pressure cylinder 8 is also provided on the lifting platform 3, and the driving shaft of the pressure cylinder 8 is rotatably connected to the fixed frame 5, and a reducer 9 is fixed to the bottom of the lifting platform 3, and the output shaft of the reducer 9 is rotatably connected to the pressure wheel 8 through a first universal joint coupling 10. A drive motor 11 is also provided on the machine platform 1, and the drive shaft of the drive motor 11 is rotatably connected to the input shaft of the reducer 9 through a second universal joint coupling 12.

[0019] After the silicon wafer is produced and formed, it will be unloaded onto the conveyor line for transportation. In actual practice, the conveyor line includes a pair of front and rear conveyor platforms, with a reversing conveyor platform set between the front and rear conveyor platforms. Generally, a pair of trimming components are set on each of the two conveyor platforms. When the silicon wafer is on the front conveyor platform and the silicon wafer passes through the trimming components, the trimming components perform the first trimming on both sides of the silicon wafer. After that, it is transported to the reversing conveyor platform. After the silicon wafer is rotated 90 degrees on the reversing conveyor platform to adjust its direction, it is then transported to the rear conveyor platform. The rear conveyor platform transports the silicon wafer to the next workstation. When the silicon wafer passes through the trimming components on the rear conveyor platform, the trimming components perform a second trimming on the other two sides of the silicon wafer. In this way, the trimming of the four sides of the silicon wafer can be completed. The belt conveyor and conveyor platform are both existing technologies, so they will not be described here.

[0020] Specifically, after the silicon wafer is transported to the belt conveyor, the lifting platform moves upward until the rotating frame lifts the silicon wafer, and the silicon wafer is a short distance away from the belt conveyor. Then the drive motor starts to work, and the output shaft of the reducer rotates under the drive motor. The pressure wheel rotates accordingly, and the pressure wheel drives the rotating frame to rotate until the rotating frame rotates to 90 degrees. At this time, the silicon wafer completes the reversal action. The lifting platform then moves downward until the silicon wafer falls back onto the belt conveyor. Finally, the belt conveyor transports the silicon wafer to the rear conveyor platform.

[0021] During the reversing process, as the rotating frame lifts the silicon wafer, the pressure cylinder begins to operate, driving the fixed frame to rotate toward the rotating frame until the pressure wheel presses against the inner wall of the rotating frame. As the drive motor drives the pressure wheel through the speed reducer, the rotating frame rotates accordingly until the silicon wafer is reversed.

[0022] In this structure, the drive motor is fixedly mounted on the platform. Its drive shaft is rotatably connected to the reducer's input shaft via a second universal joint, while the reducer's output shaft is rotatably connected to the pressure roller via a first universal joint. The second universal joint enables the platform to move vertically within a small range. The first universal joint, driven by the pressure cylinder, allows the fixed frame to rotate within a small range.

[0023] As a preferred structure, Figure 1-2 The top surface of the lifting platform 3 is rotatably provided with a circle of supporting wheels 13, and the supporting wheels 13 support the rotating frame 4. The top surface of the lifting platform 3 is located between adjacent supporting wheels 13 and is also rotatably provided with limiting wheels 14, and the limiting wheels 14 are located on the outside of the rotating frame 4.

[0024] In this structure, the pressure wheel is located on the inner side of the rotating frame, and the limiting wheel is located on the outer side of the rotating frame. Under the joint limitation of the pressure wheel and the limiting wheel, the rotating frame can be stably installed on the lifting platform. The supporting wheel supports the rotating frame. The rotating frame can be removed from the lifting platform. When the rotating frame is to be removed from the lifting platform, the pressure cylinder drives the pressure wheel to rotate backward a short distance, and the pressure moves away from the inner wall of the rotating frame, eliminating the limitation on the rotating frame. At this time, the rotating frame can be directly removed from the lifting platform.

[0025] The top surface of the rotating frame 4 is provided with a circle of support frames 15. In this embodiment, there are four support frames, evenly distributed across the top surface of the rotating frame. After the silicon wafer is delivered to the belt conveyor, the lifting platform moves upward a short distance until the support frames support the wafer, after which the rotating frame rotates to complete the reversal.

[0026] Further as a preferred structure, Figure 3 A connecting arm 16 is provided at the bottom of the lifting platform 3, and the lifting platform 3 is slidably mounted on the machine platform 1 via the connecting arm 16. A lifting cylinder 17 is provided at the bottom of the machine platform 1, and the driving shaft of the lifting cylinder 17 is connected to the connecting arm 16. When the lifting platform needs to be raised or lowered, the lifting cylinder drives the connecting arm to move vertically, and the lifting platform moves synchronously therewith.

[0027] In addition, the upper and lower sides of the platform 1 are equipped with limit posts 18 and a pair of support posts 19, respectively, facing the connecting arm. When the lifting cylinder is not operating, the two pairs of support posts support the ends of the connecting arm, and the connecting arm is at its lowest position. When the lifting platform needs to move upward until the support frame lifts the silicon wafer, the top surface of the connecting arm contacts the bottom of the limit posts, and the connecting arm is at its highest position.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
