Abstract

This invention discloses a suspended photovoltaic silicon wafer transmission device, relating to the field of silicon wafer transmission. It includes a sliding module with an internal cavity. A threaded rod is fixedly connected to the inner wall of the sliding module, and a sliding block is threadedly connected to the outer ring of the threaded rod. Rotation of an externally connected driving component causes the threaded rod to rotate. This invention drives the rotation of the threaded rod through an external driving component. When the sliding block moves below the oil outlet, the tip of the conical block contacts the side wall of the block during its movement. The subsequent continuous movement of the conical block lifts the block, causing the lubricating oil inside the oil cavity to leak through the gap between the oil outlet and the block, dripping into the square groove. The lubricating oil inside the square groove then contacts the outer wall of the threaded rod and the inner wall of the threaded groove, making the threaded connection between the threaded rod and the sliding block smoother and ensuring smoother movement of the sliding block. This intermittent oiling ensures controlled oil application.

Description

Technical Field

[0001] This invention relates to the field of silicon wafer transmission, and more specifically to a suspended photovoltaic silicon wafer transmission device. Background Technology

[0002] Silicon wafers are thin flat plates made by cutting silicon material. They are generally used in the production of semiconductor devices and photovoltaic solar panels, and are one of the essential materials in the electronics industry. Photovoltaic silicon wafers need to be transported during the processing and production of photovoltaic panels.

[0003] A Chinese patent authorization announcement (CN207116396U) discloses a device for transporting silicon wafers during the processing of solar photovoltaic silicon wafers. The device is characterized by a fixed bearing positioned on the opening of a main body box via a support frame. The main body box is horizontally positioned and has a rectangular cross-section. Guide grooves, elongated in shape, are formed on both sides of the main body box. An oblique groove is formed on the upper surface of the main body box and communicates with the guide grooves on both sides. A connecting sleeve passes through the fixed bearing and connects to a connecting ring at one end. The connecting sleeve has a keyway. The connecting ring is located inside the main body box. A spiral shaft is placed inside the main body box, with one end resting on the connecting ring. A push plate is placed in the oblique groove. Two push rollers are positioned on each side of the push plate. Two limiting grooves are formed on the upper surface of the push plate. Two suspension frames are positioned on each side of the push plate, and each suspension frame has a silicon wafer fixing groove.

[0004] The existing silicon wafer transport device still has the following problems when in use: When the spiral shaft and the push plate are connected, the resistance generated by the friction between the two over a long period of time may affect the smoothness and stability of the subsequent push plate movement, thus hindering the subsequent silicon wafer transport process.

[0005] Therefore, it is necessary to invent a suspended photovoltaic silicon wafer transmission device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a suspended photovoltaic silicon wafer transmission device to solve the problem mentioned in the background art that when the spiral shaft and the push plate are connected, the resistance generated by the long-term friction between them may affect the smoothness and stability of the subsequent movement of the push plate, thus hindering the subsequent transmission process of the silicon wafer.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a suspended photovoltaic silicon wafer transmission device, comprising a sliding module, wherein the sliding module has an inner cavity, and a threaded rod is fixedly connected to the inner wall of the inner cavity, and a sliding block is threadedly connected to the outer ring of the threaded rod. The rotation of a driving component connected externally to the threaded rod causes the threaded rod to rotate, thereby causing the sliding block, which is threadedly connected to the threaded rod, to move linearly under the constraint of the inner cavity. A mechanical suction cup is installed at the bottom of the sliding block, which picks up and transmits the silicon wafer to be processed. An oil cavity is opened inside the sliding module, and an oil filling port is opened at the top of the oil cavity. A sealing plug is installed at the oil filling port, and an oil outlet is opened at the lower end of the oil cavity. A plug is movably installed inside the oil outlet, and a long rod is fixedly connected to the top of the plug. A disc is threadedly connected to the upper end of the long rod. This movably installed plug enables intermittent oil discharge from the oil outlet, facilitating intermittent oiling of the threaded rod and the sliding block, ensuring smooth movement of the sliding block, and eliminating the need for manual oiling. The operation is convenient and quick. The device also includes:

[0008] The components can be replaced. The inside of the disc is rotatably connected to an annular block one, and a spring is fixedly connected between annular block one and annular block two. The spring is movably fitted on the outer ring of the long rod, and annular block two is rotatably connected to the sliding module, which facilitates the replacement of the spring.

[0009] The ejector assembly has a square groove inside the sliding block, which is connected to a gear groove. A gear is rotatably connected inside the gear groove. The gear meshes with a toothed plate fixedly connected to the inner cavity sidewall. A through hole is opened inside the gear, and a pointed cone block is fixedly connected inside the through hole through a connecting block. The movement of the pointed cone block lifts the block to achieve oil discharge from the oil outlet.

[0010] Preferably, the threaded rod is threadedly connected to the threaded groove reserved inside the sliding block, and the threaded groove is connected to the square groove and the gear groove, so that the oil leaking from the oil outlet 8 can come into contact with the threaded groove and the threaded rod.

[0011] Preferably, there is a gap between the top of the sliding block and the top of the inner cavity, and the upper end of the pointed cone block installed inside the sliding block contacts the top wall of the inner cavity and is in a sliding connection. In this way, the movement of the pointed cone block can lift the block and realize the oil outlet.

[0012] Preferably, both the oil outlet and the plug are in the shape of an inverted frustum, and the outer wall of the plug is attached to the outer wall of the oil outlet and is slidably connected. The lower end of the plug extends to the outside and below the oil outlet, so that the movement of the cone block can lift the plug and realize the oil outlet.

[0013] Preferably, the outer walls of the blocking blocks are all smooth arc-shaped surfaces, and the outer walls of the blocking blocks are in contact with the outer walls of the pointed cone blocks and are in a sliding connection.

[0014] Preferably, the first annular block consists of two annular blocks that are integrally installed. The lower end of the annular block with a larger outer diameter is fixedly connected to the annular block with a smaller outer diameter. The outer wall of the first annular block is attached to the inner wall of the groove reserved inside the disc and is movably connected. In this way, when the spring is replaced later, the rotating disc will not be obstructed by the spring, ensuring that the spring replacement is relatively smooth.

[0015] Preferably, the second annular block is symmetrically arranged with the lower annular block of the first annular block, and the second annular block is attached to the inner wall of the groove reserved inside the sliding module and presents a movable connection.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] 1. This invention drives the rotation of the threaded rod through an external drive component, causing the sliding block to move linearly inside the cavity. This, in turn, moves the mechanical suction cup installed at the bottom of the sliding block to pick up the photovoltaic silicon wafer to be transferred and then transfer it. When the sliding block moves to below the oil outlet, the tip of the cone block contacts the side wall of the block during its movement. The cone block continues to move and lifts the block, causing the lubricating oil inside the oil cavity to leak out through the gap between the oil outlet and the block and drip into the square groove. The lubricating oil inside the square groove then contacts the outer wall of the threaded rod and the inner wall of the threaded groove, making the threaded connection between the threaded rod and the sliding block smoother and ensuring smoother movement of the sliding block. This intermittent oiling can ensure that the amount of oil applied is controlled.

[0018] 2. The gears inside the sliding block rotate synchronously and mesh with the toothed plate, causing the gears to rotate. This causes the cone blocks fixed inside the gears to rotate synchronously, making it easier to lift the block.

[0019] 3. After twisting the disc, remove the spring connected to the bottom of the annular block one that rotates inside the disc and replace it. The second annular block fixedly connected to the lower end of the new spring matches the groove reserved on the top of the sliding module. Align the disc with the thread on the outer ring of the upper end of the long rod and twist to install. In this way, the spring can be used smoothly. The spring applies pressure to the long rod and the plug, so that the plug matches the oil outlet perfectly and avoids oil leakage inside the oil chamber. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] This invention provides, for example Figure 1-6The suspended photovoltaic silicon wafer transport device shown includes a sliding module 1. The sliding module 1 has an inner cavity 2, and a threaded rod 3 is fixedly connected to the inner wall of the inner cavity 2. A sliding block 4 is threadedly connected to the outer ring of the threaded rod 3. Rotation of a driving component connected externally to the threaded rod 3 causes the threaded rod 3 to rotate, thereby causing the sliding block 4, which is threadedly connected to the threaded rod 3, to move linearly within the inner cavity 2. A mechanical suction cup 5 is installed at the bottom of the sliding block 4. The mechanical suction cup 5 picks up and transports the silicon wafer to be processed. The sliding module 1... The interior of the device has an oil cavity 6, and the top of the oil cavity 6 has an oil filling port 7. A sealing plug is installed at the oil filling port 7, and the lower end of the oil cavity 6 has an oil outlet 8. A plug 9 is movably installed inside the oil outlet 8, and a long rod 10 is fixedly connected to the top of the plug 9. A disc 11 is threadedly connected to the upper end of the long rod 10. This movably installed plug 9 enables intermittent oil discharge from the oil outlet 8, which facilitates intermittent oiling of the threaded rod 3 and the sliding block 4, ensuring smooth movement of the sliding block 4. No manual oiling is required, making operation convenient and quick. It also includes:

[0032] Replace component 13. The inside of the disc 11 is rotatably connected to an annular block 131, and a spring 12 is fixedly connected between an annular block 131 and an annular block 132. The spring 12 is movably fitted on the outer ring of the long rod 10, and the annular block 132 is rotatably connected to the sliding module 1, which facilitates the replacement of the spring 12.

[0033] The ejector assembly 14 has a square groove 141 inside the sliding block 4, which is connected to the gear groove 142. A gear 143 is rotatably connected inside the gear groove 142. The gear 143 meshes with a toothed plate 147 fixedly connected to the side wall of the inner cavity 2. A through hole 144 is opened inside the gear 143, and a pointed cone block 146 is fixedly connected inside the through hole 144 through a connecting block 145. The movement of the pointed cone block 146 lifts the block 9 to realize the oil outlet 8. At the same time, the oil flowing out of the oil outlet 8 drips into the square groove 141 through the through hole 144.

[0034] The threaded rod 3 and the threaded groove reserved inside the sliding block 4 are connected by threads. The threaded groove is connected to the square groove 141 and the gear groove 142. This facilitates the contact between the oil leaking from the oil outlet 8 and the threaded groove and the threaded rod 3, which lubricates the connection between the threaded groove and the threaded rod 3 and ensures that the sliding block 4 moves smoothly without jamming.

[0035] There is a gap between the top of the sliding block 4 and the top of the inner cavity 2, and the upper end of the pointed cone block 146 installed inside the sliding block 4 contacts the top wall of the inner cavity 2 and is in a sliding connection. In this way, the movement of the pointed cone block 146 can lift the block block 9 to realize the oil outlet 8.

[0036] Both the oil outlet 8 and the plug 9 are inverted frustum shapes, and the outer wall of the plug 9 is attached to the outer wall of the oil outlet 8 and forms a sliding connection. The lower end of the plug 9 extends to the outside and below the oil outlet 8, so that the movement of the cone block 146 can lift the plug 9 to realize the oil outlet 8.

[0037] The outer walls of the block 9 are all smooth arc surfaces, and the outer walls of the block 9 are in contact with the outer walls of the cone block 146 and are in a sliding connection.

[0038] The annular block 131 consists of two annular blocks that are installed as a single unit. The lower end of the outer ring block with a larger outer diameter is fixedly connected to the outer ring block with a smaller outer diameter. The outer wall of the annular block 131 is attached to the inner wall of the groove reserved inside the disc 11 and is movably connected. In this way, when the spring 12 is replaced later, the disc 11 will not be obstructed by the spring 12, ensuring that the replacement of the spring 12 is relatively smooth.

[0039] The second annular block 132 is symmetrically arranged with the lower annular block of the first annular block 131, and the second annular block 132 is attached to the inner wall of the reserved channel inside the sliding module 1 and presents a movable connection.

[0040] Working principle: When using a suspended photovoltaic silicon wafer transmission device, the external drive component first drives the threaded rod 3 to rotate. The sliding block 4, which is threadedly connected to the threaded rod 3, moves linearly under the constraint of the inner cavity 2. This facilitates the movement of the mechanical suction cup 5 installed at the bottom of the sliding block 4. The mechanical suction cup 5 picks up the photovoltaic silicon wafer to be transmitted and performs subsequent transmission. At the same time, during the linear movement of the sliding block 4, when the sliding block 4 moves to below the oil outlet 8, the top of the pre-made pointed cone block 146 inside the sliding block 4 contacts the side wall of the block block 9 during its movement. The subsequent continuous movement of the cone block 146 pushes up the block block 9. The upward movement of the block block 9 creates a gap between the block block 9 and the oil outlet 8. This allows the lubricating oil inside the oil chamber 6 to leak out through the gap between the oil outlet 8 and the block block 9 and drip into the square groove 141. At the same time, the square groove 141 and the threaded groove between the threaded rod 3 and the sliding block 4 are connected. This allows the lubricating oil inside the square groove 141 to come into contact with the outer wall of the threaded rod 3 and the inner wall of the threaded groove. This makes the threaded connection between the threaded rod 3 and the sliding block 4 smoother and ensures that the movement of the sliding block 4 is smoother.

[0041] Meanwhile, as the sliding block 4 moves, the gear 143 rotatably connected in the gear groove 142 inside the sliding block 4 is displaced synchronously. In this way, the gear 143 meshes with the toothed plate 147 fixedly connected to the inner wall of the inner cavity 2 during the movement, causing the gear 143 to rotate. This causes the pointed cone block 146 fixedly connected to the gear 143 through the connecting block 145 to rotate synchronously. This makes it easier to lift the block block 9 while the pointed cone block 146 rotates and moves.

[0042] As the sliding block 4 moves, the cone block 146 moves synchronously and moves away from below the block 9. At this time, the spring 12 loses external force and resets, causing the block 9 to descend and re-match with the oil outlet 8, preventing lubricating oil from leaking out of the oil outlet 8. In this way, the threaded rod 3 will only be lubricated when the sliding block 4 passes below the oil outlet 8. This intermittent lubrication can ensure that the amount of oil applied is controlled.

[0043] When spring 12 needs to be replaced after a long period of use, twist disc 11 so that disc 11, which is threadedly connected to long rod 10, rotates away from the end of long rod 10. Then, spring 12, which is connected to the bottom of annular block 131 rotatably connected inside disc 11, can be removed and replaced. Match the annular block 132, which is fixedly connected to the lower end of the new spring 12, with the corresponding groove. Then, align disc 11 with the thread on the outer ring of the upper end of long rod 10 and twist it for installation. In this way, spring 12 can be used smoothly. This ensures that spring 12 applies force to block block 9 and prevents oil leakage inside oil chamber 6 when no sliding block 4 passes under oil outlet 8.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
