Description

Technical Field

[0001] This utility model relates to the field of perovskite material preparation technology, and in particular to an adjustable perovskite precursor coating device. Background Technology

[0002] Perovskite materials, due to their excellent photoelectric properties, have broad application prospects in fields such as solar cells and light-emitting diodes. In the preparation process of perovskite materials, the coating process of the precursor plays a crucial role in the performance of the final product. Currently, traditional perovskite precursor coating equipment suffers from several problems during use. For example, vibrations generated during equipment operation can lead to decreased coating accuracy, resulting in uneven coating thickness, coating misalignment, and other quality issues.

[0003] Chinese patent application CN202323669598.7 discloses a high-precision perovskite coating device. The key technical points are: it includes a frame, a worktable for placing workpieces fixedly connected to the frame, and a two-axis motion track with two parallel rails. The worktable is located between the two-axis motion tracks, and a lifting mechanism is slidably connected to the two-axis motion tracks. The lifting mechanism is connected to a coating beam cutter head, which can be raised and lowered under the drive of the lifting mechanism and can slide relative to the two-axis motion tracks together with the lifting mechanism. Through the two-axis motion tracks and the worktable fixed to the frame, the coating beam cutter head slides along the two-axis motion tracks with the lifting mechanism, thus preventing the worktable from moving relative to the frame and avoiding uneven coating caused by vibration from worktable movement. Simultaneously, the sliding of the beam cutter head on the two-axis motion tracks, through the cooperation between the two-axis motion tracks, minimizes coating unevenness caused by track gaps. Furthermore, by using a beam cutter head instead of a nozzle for coating, the precision is improved. Compared with existing technologies, the high-precision perovskite coating device disclosed in this application can achieve higher coating accuracy. The inventors believe that the following defects often exist: the vibration generated by the operation of the coating machine body will cause the relative position of the coating head and the substrate to be unstable, resulting in uneven coating thickness, coating displacement, and missed coating, which will affect the performance of perovskite thin films and reduce the yield of batteries and other devices; therefore, an adjustable perovskite precursor coating device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where vibrations generated during the operation of the coating machine body cause instability in the relative positions of the coating head and the substrate. This invention proposes an adjustable perovskite precursor coating device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable perovskite precursor coating device, comprising a coating machine body, wherein a shock-absorbing device is provided on the surface of the coating machine body, the shock-absorbing device comprising four fixed chambers, all four fixed chambers being fixedly connected to the surface of the coating machine body, a square block being slidably connected to the surface of the fixed chamber, a shock-absorbing pad being fixedly connected to the surface of the square block, and a connecting plate being fixedly connected to one side of the square block.

[0006] The effect achieved by the above-mentioned components is as follows: by setting up a shock absorption device, the vibration of the coating machine body is reduced, avoiding the vibration generated by the operation of the coating machine body, which would cause the relative position of the coating head and the substrate to be unstable, resulting in uneven coating thickness, coating displacement, missed coating, etc., which would affect the performance of the perovskite film and reduce the yield of batteries and other devices, thus improving the practicality of the device.

[0007] Preferably, four fixing plates are fixedly connected to both sides of the coating machine body, and the eight fixing plates are grouped in pairs. The surface of the fixing plate is fixedly connected to a fixing rod, and the arc surfaces of the two fixing rods are slidably connected to a shaped frame. The surface of the shaped frame is slidably connected to the coating machine body, and the inner surface of the shaped frame is slidably connected to a connecting plate. Bolts are inserted into the internal threads of the shaped frame.

[0008] The aforementioned components achieve the following effects: they fix the position of the shock-absorbing pads, ensuring that the device maintains a stable structural state while the coating machine is running, keeping the relative positions of the shock-absorbing pads, square blocks, and other components unchanged with respect to the coating machine body, continuously and reliably absorbing and buffering equipment vibrations, ensuring the stability of the coating process, and improving the coating accuracy of perovskite precursors.

[0009] Preferably, the arc surface of the fixing rod is fitted with a spring, and the two ends of the spring are fixedly connected to the fixing plate and the irregular frame, respectively.

[0010] The aforementioned components achieve the following effects: they improve the stability of the irregular frame, keeping it stable in the elevated position. This allows for easy replacement of the shock-absorbing pads by the spring force, ensuring sufficient space for installation and avoiding repeated manual adjustments to the frame's position. This improves replacement efficiency and ensures a more efficient, convenient, and stable process for installing and removing the shock-absorbing pads.

[0011] Preferably, the arc surface of the bolt is fixedly connected to a baffle plate, and the surface of the baffle plate is in contact with the irregular frame.

[0012] The aforementioned components achieve the following effect: preventing bolts from being pulled out, thus avoiding situations where workers turn the bolts too many times, causing the bolt's arc surface to separate from the irregular frame, requiring secondary installation and increasing the workload of workers.

[0013] Preferably, the coating machine body is provided with heat dissipation devices on both sides. The two heat dissipation devices include two U-shaped frames, which are fixedly connected to the two sides of the coating machine body respectively. A filter screen is slidably connected inside the U-shaped frame. Two round rods are fixedly connected to the surface of the filter screen. A single-hole plate is rotatably connected to the arc surface of the round rod. Two L-shaped plates are fixedly connected to the upper surface of the U-shaped frame. Insert rods are slidably inserted into the L-shaped plates. Two positioning plates are fixedly connected to the surface of the U-shaped frame.

[0014] The effect achieved by the above components is as follows: by setting up a heat dissipation device, the temperature inside the coating machine body is reduced. Perovskite precursors are sensitive to temperature. This avoids the coating machine body from working for a long time and the temperature inside the coating machine body continuously rising. High temperature will cause the precursor solution to undergo chemical reactions or abnormal volatilization, resulting in poor film quality, cracks, holes and other defects in the film, which will reduce the photoelectric performance and pass rate of the final product. This improves the practicality of the device.

[0015] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to the round rod and the single-hole plate, respectively.

[0016] The effect achieved by the above components is to automatically open the single-hole plate while keeping the single-hole plate in the open state.

[0017] Preferably, an absorbent pad is fixedly connected to one side of the positioning plate, and the surface of the absorbent pad is in contact with the single-hole plate.

[0018] The effect achieved by the above components is to absorb the collision force between the single-hole plate and the positioning plate, avoid wear, deformation or loosening of components such as the single-hole plate and positioning plate due to rigid collision, and extend the service life of each component.

[0019] In summary, the beneficial effects of this utility model are as follows: 1. In this utility model, by setting a shock-absorbing device, the vibration of the coating machine body is reduced, avoiding the vibration generated by the operation of the coating machine body, which would cause the relative position of the coating head and the substrate to be unstable, resulting in uneven coating thickness, coating displacement, missed coating, etc., which would affect the performance of the perovskite film and reduce the yield of batteries and other devices, thus improving the practicality of the device.

[0020] 2. In this utility model, by setting up a heat dissipation device, the temperature inside the coating machine body is reduced. The perovskite precursor is sensitive to temperature. This avoids the coating machine body from working for a long time and the temperature inside the coating machine body continuously rising. High temperature will cause the precursor solution to undergo chemical reactions or abnormal volatilization, resulting in poor film quality, cracks, holes and other defects in the film, which will reduce the photoelectric performance and pass rate of the final product. This improves the practicality of the device. Attached Figure Description

[0023] Reference Figure 1As shown, this utility model provides a technical solution: an adjustable perovskite precursor coating device, including a coating machine body 1. The surface of the coating machine body 1 is provided with a shock-absorbing device 2. By setting the shock-absorbing device 2, the vibration of the coating machine body 1 is reduced, preventing the vibration generated during operation from causing instability in the relative position of the coating head and substrate, leading to uneven coating thickness, coating misalignment, and missed coating, thus affecting the performance of the perovskite film and reducing the yield of batteries and other devices. This improves the practicality of the device. Heat dissipation devices 3 are provided on both sides of the coating machine body 1. By setting the heat dissipation devices 3, the temperature inside the coating machine body 1 is reduced. Perovskite precursors are sensitive to temperature; this prevents the coating machine body 1 from operating for extended periods, causing a continuous rise in temperature inside the coating machine body 1. High temperatures can cause chemical reactions or abnormal volatilization of the precursor solution, leading to poor film quality, cracks, holes, and other defects in the film, resulting in reduced photoelectric performance and yield of the final product. This improves the practicality of the device.

[0024] The following section will explain the specific setup and function of its shock absorption device 2 and heat dissipation device 3.

[0025] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the shock absorption device 2 includes four fixed chambers 201, all four fixed chambers 201 are fixedly connected to the surface of the coating machine body 1, square blocks 202 are slidably connected to the surface of the fixed chambers 201, shock absorption pads 203 are fixedly connected to the surface of the square blocks 202, a connecting plate 204 is fixedly connected to one side of the square blocks 202, four fixed plates 205 are fixedly connected to both sides of the coating machine body 1, the eight fixed plates 205 are grouped in pairs, fixed rods 206 are fixedly connected to the surface of the fixed plates 205, irregularly shaped frames 207 are slidably connected to the arc surfaces of two fixed rods 206, the surface of the irregularly shaped frame 207 is slidably connected to the coating machine body 1, the inner surface of the irregularly shaped frame 207 is slidably connected to the connecting plate 204, and the irregularly shaped frame 207 is internally threaded. With bolt 208, when the worker needs to install the shock-absorbing pad 203, first, the worker pulls the irregular frame 207 and slides it on the arc surface of the fixed rod 206 until the irregular frame 207 no longer affects the movement of the connecting plate 204. Then, the worker can push the connecting plate 204 to move the square block 202 until the surface of the square block 202 is completely in contact with the fixed chamber 201. At this time, the worker can release the irregular frame 207. The irregular frame 207 slides on the arc surface of the fixed rod 206 under the influence of gravity until the irregular frame 207 moves to its maximum distance. Then, the worker can rotate the bolt 208 inside the irregular frame 207 until the bolt 208 is inserted into the connecting plate 204. At this time, the position of the shock-absorbing pad 203 is fixed, ensuring the device is in place. During operation, the coating machine body 1 maintains a stable structural state, ensuring that the relative positions of components such as the shock-absorbing pad 203 and the square block 202 remain unchanged. This continuously and reliably absorbs and buffers equipment vibrations, guaranteeing a stable coating process and improving the coating accuracy of the perovskite precursor. A spring 210 is fitted onto the arc surface of the fixing rod 206. The two ends of the spring 210 are fixedly connected to the fixing plate 205 and the irregular frame 207, respectively. When the operator needs to disassemble the shock-absorbing pad 203, the spring 210 is in a stretched state. First, the operator rotates the bolt 208 within the irregular frame 207 until the arc surface of the bolt 208 separates from the connecting plate 204. Then, the rebound force of the spring 210 causes the irregular frame 207 to slide on the arc surface of the fixing rod 206. Until the surface of the irregular frame 207 separates from the connecting plate 204, the stability of the irregular frame 207 is improved, keeping it stable in the raised position. This facilitates easy replacement of the shock absorber 203 by the staff. The spring force of the spring 210 keeps the irregular frame 207 stable in the raised position, providing sufficient space for the installation of the new shock absorber 203 and avoiding repeated manual adjustments to the position of the irregular frame 207, thus improving replacement efficiency and ensuring a more efficient, convenient, and stable process for the installation and removal of the shock absorber 203. The arc surface of the bolt 208 is fixedly connected to the blocking plate 209, and the surface of the blocking plate 209 is in contact with the irregular frame 207. When the staff needs to replace the shock absorber 203, they first rotate the bolt 208 to move the blocking plate 209.Until the surface of the baffle plate 209 is in contact with the irregular frame 207, the arc surface of the bolt 208 is completely separated from the connecting plate 204. This achieves the effect of preventing the bolt 208 from being pulled out, avoiding the situation where the operator turns the bolt 208 too many times, causing the arc surface of the bolt 208 to separate from the irregular frame 207, requiring secondary installation during use and increasing the workload of the operator.

[0026] Reference Figure 5 and Figure 6 As shown, specifically, the two heat dissipation devices 3 include two U-shaped frames 31, which are fixedly connected to both sides of the coating machine body 1. A filter screen 32 is slidably connected inside the U-shaped frame 31. Two round rods 33 are fixedly connected to the surface of the filter screen 32. A single-hole plate 34 is rotatably connected to the arc surface of the round rods 33. Two L-shaped plates 35 are fixedly connected to the upper surface of the U-shaped frame 31. A rod 36 is slidably inserted into the L-shaped plate 35. Two positioning plates 38 are fixedly connected to the surface of the U-shaped frame 31. A torsion spring 37 is sleeved on the arc surface of the round rods 33. The two ends of the torsion spring 37 are fixedly connected to the round rods 33 and the single-hole plate 34, respectively. When the operator needs to clean the dust on the surface of the filter screen 32, the operator first pulls the rod 36 to slide it inside the L-shaped plate 35 until the arc surface of the rod 36 separates from the single-hole plate 34. Then, the torque of the torsion spring 37 drives the single-hole plate 34 to move until the single-hole plate 34... The surface of the filter screen 32 is in contact with the positioning plate 38. Then, the operator can pull the filter screen 32 to slide within the U-shaped frame 31 until the filter screen 32 separates from the U-shaped frame 31. At this point, the single-hole plate 34 is automatically opened and kept in the open state. An absorbent pad 39 is fixedly connected to one side of the positioning plate 38. The surface of the absorbent pad 39 is in contact with the single-hole plate 34. When the operator needs to clean the filter screen 32, the operator first pulls the insertion rod 36 to slide within the L-shaped plate 35 until the arc surface of the insertion rod 36 separates from the single-hole plate 34. Then, the torque of the torsion spring 37 drives the single-hole plate 34 to move until the surface of the single-hole plate 34 is in contact with the absorbent pad 39. At this point, the collision force between the single-hole plate 34 and the positioning plate 38 is absorbed, avoiding wear, deformation, or loosening of components such as the single-hole plate 34 and the positioning plate 38 due to rigid collision, thus extending the service life of each component.

[0027] Working principle: When the worker needs to install the shock-absorbing pad 203, firstly, the worker pulls the irregular frame 207 to slide on the arc surface of the fixed rod 206 until the irregular frame 207 no longer affects the movement of the connecting plate 204. Then, the worker can push the connecting plate 204 to move the square block 202 until the surface of the square block 202 is completely in contact with the fixed chamber 201. At this time, the worker can release the irregular frame 207. The irregular frame 207 slides on the arc surface of the fixed rod 206 under the influence of gravity until the irregular frame 207 has moved to its maximum distance. Then, the worker can rotate the bolt 208 inside the irregular frame 207 until the bolt 208 is inserted into the connecting plate 204. When the worker needs to remove the shock-absorbing pad 203, the spring... When the spring 210 is in a stretched state, the operator first rotates the bolt 208 to move the baffle plate 209 until the surface of the baffle plate 209 is in contact with the irregular frame 207. At this time, the arc surface of the bolt 208 is completely separated from the connecting plate 204. Then, the rebound force of the spring 210 drives the irregular frame 207 to slide on the arc surface of the fixed rod 206 until the surface of the irregular frame 207 is separated from the connecting plate 204. This achieves the effect of reducing the vibration of the coating machine body 1, avoiding the vibration generated by the operation of the coating machine body 1, which would cause the relative position of the coating head and the substrate to be unstable, resulting in uneven coating thickness, coating offset, missed coating, etc., which would affect the performance of the perovskite film and reduce the yield of batteries and other devices, thus improving the practicality of the device.

[0028] When the staff needs to clean the dust on the surface of the filter screen 32, firstly, the staff pulls the insertion rod 36 and slides it within the L-shaped plate 35 until the arc surface of the insertion rod 36 separates from the single-hole plate 34. Then, the torque of the torsion spring 37 drives the single-hole plate 34 to move until the surface of the single-hole plate 34 is in contact with the positioning plate 38. Then, the staff can pull the filter screen 32 and slide it within the U-shaped frame 31 until the filter screen 32 separates from the U-shaped frame 31. When the staff needs to clean the filter screen 32, firstly, the staff pulls the insertion rod 36 and slides it within the L-shaped plate 35 until the insertion rod 36... The arc surface separates from the single-hole plate 34, and then the torque of the torsion spring 37 drives the single-hole plate 34 to move until the surface of the single-hole plate 34 is in contact with the absorption pad 39, which achieves the effect of reducing the temperature inside the coating machine body 1. The perovskite precursor is sensitive to temperature. To avoid the coating machine body 1 working for a long time, the temperature inside the coating machine body 1 will continue to rise. High temperature will cause the precursor solution to undergo chemical reaction or abnormal volatilization, resulting in poor film quality, cracks, holes and other defects in the film, which will reduce the photoelectric performance and pass rate of the final product. This improves the practicality of the device.
