Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser processing equipment technology, and in particular to an automatic calibration and positioning platform for laser scribing substrates. Background Technology
[0002] Laser scribing, a key technology in the field of laser processing, uses a high-energy laser beam to locally act on a substrate, achieving high-precision pattern processing and line etching. In precision manufacturing scenarios such as semiconductor packaging, electronic component manufacturing, and photovoltaic cell processing, the positioning accuracy of the substrate directly determines the product yield and performance stability. If the substrate is not completely constrained by a placement plate alone, it may shift due to slight external forces or vibrations during laser scribing, causing the laser-scribed pattern or lines to deviate from the preset position, resulting in reduced scribing accuracy and compromised product quality.
[0003] The inventors believe that the following defects often exist: the placement plate is difficult to completely constrain the substrate. During laser scribing, the substrate may be displaced due to slight external force or vibration, causing the laser scribing pattern or line to deviate from the preset position, resulting in reduced scribing accuracy and damaged product quality. Therefore, an automatic calibration and positioning platform for substrates for laser scribing is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty of the placement plate fully constraining the substrate, and the potential displacement of the substrate due to slight external force or vibration during laser scribing. Therefore, this invention proposes an automatic calibration and positioning platform for the substrate used in laser scribing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic calibration and positioning platform for laser scribing substrates, comprising a positioning platform body, a placement plate mounted on the surface of the positioning platform body, a clamping device provided on the upper surface of the positioning platform body, the clamping device comprising two adjusting plates, the two adjusting plates being fixedly connected to the upper surface of the positioning platform body, a shaped frame slidably connected inside the adjusting plates, a connecting rod fixedly connected inside the shaped frame, a clamping plate rotatably connected to the arc surface of the connecting rod, a friction pad fixedly connected to one side of the clamping plate, a round rod fixedly connected to the surface of the shaped frame, a rotating plate rotatably connected to the arc surface of the round rod, a square groove opened on the surface of the shaped frame, and an insert rod slidably inserted inside the shaped frame.
[0006] The effect achieved by the above components is as follows: by setting up a clamping device, the substrate is clamped, avoiding the situation where the substrate cannot be fully constrained by the placement plate alone. During laser scribing, the substrate may be displaced due to slight external force or vibration, causing the laser scribing pattern or line to deviate from the preset position, resulting in reduced scribing accuracy and product quality damage, thus improving the reliability of the device.
[0007] Preferably, the arc surfaces at both ends of the connecting rod are fitted with torsion springs, and the two ends of the torsion springs are fixedly connected to the irregular frame and the clamping plate, respectively.
[0008] The above-mentioned components achieve the following effects: they automatically open the clamping plate and keep it in the open position, making it convenient for operators to perform further operations, reducing the number of operation steps for operators, and improving their work efficiency.
[0009] Preferably, a single-sided plate is fixedly connected to the surface of the irregular frame, an adjusting rod is slidably inserted into the single-sided plate, a plurality of circular holes are opened on the surface of the adjusting plate, the arc surface of the adjusting rod is slidably connected to the circular holes of the adjusting plate, and a first spring is sleeved on the arc surface of the adjusting rod, with the two ends of the first spring being fixedly connected to the single-sided plate and the adjusting rod respectively.
[0010] The aforementioned components achieve the following effects: they enable the adjustment of the irregular frame position, allowing for convenient and precise adjustment of the irregular frame position. They can quickly and flexibly adjust the irregular frame position according to the clamping requirements of substrates of different sizes, thereby changing the position of the clamping plate. This allows the device to be adapted to the fixing of substrates of various specifications, effectively improving the platform's compatibility with substrates of different sizes.
[0011] Preferably, a blocking plate is fixedly connected to the arc surface of the adjusting rod, and the size of the adjusting rod is adapted to the size of the circular hole of the adjusting plate.
[0012] The aforementioned components achieve the following effect: they prevent damage to the first spring, avoiding situations where the adjustment rod is pulled too far by the operator, causing the stress range of the first spring to be exceeded, resulting in loss of elasticity and making it difficult to use normally.
[0013] Preferably, heat dissipation devices are provided on both sides of the positioning platform body. The two heat dissipation devices include two fixed frames, which are fixedly connected to both sides of the positioning platform body respectively. A dustproof net is slidably connected inside the fixed frame, and two handles are fixedly connected to the surface of the dustproof net.
[0014] The aforementioned components achieve the following effect: reducing the internal temperature of the positioning platform body, preventing the internal temperature from continuously rising during continuous operation. Continuous high-temperature operation would accelerate the wear and aging of the internal components of the positioning platform body, significantly shorten the overall service life of the equipment, increase the frequency of equipment replacement and the company's equipment procurement costs, and improve the practicality of the device.
[0015] Preferably, two fixing rods are fixedly connected to both sides of the fixing frame, and a single-hole plate is slidably connected to the arc surface of the fixing rod. A limit rod is fixedly connected to one side of the single-hole plate, and two limit holes are opened on both sides of the fixing frame.
[0016] The aforementioned components achieve the following effects: they allow for the removal of dustproof nets, facilitating regular cleaning by staff, ensuring the dustproof nets continue to function effectively, maintaining the efficient operation of the device, protecting the internal components of the positioning platform from dust intrusion, and thus improving the stability and lifespan of the equipment.
[0017] Preferably, a second spring is fitted onto the arc surface of the fixing rod, and the two ends of the second spring are fixedly connected to the fixing rod and the single-hole plate, respectively.
[0018] The aforementioned components achieve the following effects: they improve the stability of the limiting rod, ensuring that the limiting rod remains firmly and tightly against the dustproof net after installation, preventing the limiting rod from loosening or falling off due to equipment vibration or external forces, ensuring that the dustproof net is reliably fixed in position during use, and effectively improving the stability and sealing of the dustproof net after installation.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting a clamping device, the effect of clamping the substrate is achieved, avoiding the difficulty of completely constraining the substrate by simply placing the plate. During laser scribing, the substrate may be displaced due to slight external force or vibration. As a result, when laser scribing the substrate, the pattern or line of the laser scribing deviates from the preset position due to the certain movement of the substrate position, causing damage to the substrate quality, making the substrate unusable, and wasting raw materials. This improves the practicality of the device.
[0021] 2. In this utility model, by setting up a heat dissipation device, the internal temperature of the positioning platform body is reduced, which avoids the continuous rise in internal temperature of the positioning platform body during continuous operation. Continuous high temperature operation will accelerate the wear and aging of the internal components of the positioning platform body, causing some internal parts of the platform body to reach the end of their service life prematurely, resulting in increased replacement frequency of equipment parts and increased equipment procurement costs for enterprises, thus improving the practicality of the device.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: an automatic calibration and positioning platform for laser scribing substrates, including a positioning platform body 1, a placement plate 2 mounted on the surface of the positioning platform body 1, and a clamping device 3 provided on the upper surface of the positioning platform body 1. By setting the clamping device, the substrate is clamped, avoiding the situation where the placement plate alone cannot completely constrain the substrate. During laser scribing, the substrate may be displaced due to slight external force or vibration. As a result, when the substrate is laser scribing, the pattern or line of the laser scribing deviates from the preset position due to the certain displacement of the substrate position, causing damage to the substrate quality, making the substrate unusable, and wasting raw materials. This improves the practicality of the device. Heat dissipation devices 4 are provided on both sides of the positioning platform body 1. By setting the heat dissipation devices, the internal temperature of the positioning platform body is reduced, avoiding the continuous rise in internal temperature during continuous operation. Continuous high temperature operation will accelerate the wear and aging of internal components of the positioning platform body, causing some internal parts of the platform body to reach the end of their service life prematurely, resulting in increased replacement frequency of equipment parts and increased equipment procurement costs for enterprises. This improves the practicality of the device.
[0029] The specific setup and function of its clamping device 3 and heat dissipation device 4 will be explained below.
[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the clamping device 3 includes two adjusting plates 301, which are fixedly connected to the upper surface of the positioning platform body 1. A shaped frame 302 is slidably connected inside the adjusting plate 301. A connecting rod 305 is fixedly connected inside the shaped frame 302. A clamping plate 306 is rotatably connected to the arc surface of the connecting rod 305. A friction pad 312 is fixedly connected to one side of the clamping plate 306. A round rod 303 is fixedly connected to the surface of the shaped frame 302. A rotating plate 304 is rotatably connected to the arc surface of the round rod 303. A square groove is opened on the surface of the shaped frame 302. An insert rod 307 is slidably inserted inside the shaped frame 302. Torsion springs 313 are sleeved on the arc surfaces of both ends of the connecting rod 305. The two ends of the torsion springs 313 are respectively connected to the shaped frame 302 and the clamping plate 306. The plate 306 is fixedly connected. When the operator needs to remove the already marked substrate, firstly, the operator pulls the insertion rod 307 and slides it within the irregular frame 302 until the arc surface of the insertion rod 307 separates from the rotating plate 304. Then, the operator rotates the rotating plate 304 within the square groove of the irregular frame 302 until the surface of the rotating plate 304 separates from the clamping plate 306. Then, the torque of the torsion spring 313 drives the clamping plate 306 to rotate on the arc surface of the connecting rod 305. The clamping plate 306 drives the friction pad 312 to move until the clamping plate 306 no longer affects the movement of the substrate. Then, the operator can remove the substrate. At this point, the clamping plate 306 is automatically opened, while simultaneously keeping the clamping plate 306 in the open state for the convenience of the operator. Further operations are performed, reducing the number of steps for workers and improving their efficiency. A single-sided plate 308 is fixedly connected to the surface of the irregularly shaped frame 302. An adjusting rod 309 is slidably inserted into the single-sided plate 308. Several circular holes are formed on the surface of the adjusting plate 301. The arc surface of the adjusting rod 309 is slidably connected to the circular holes of the adjusting plate 301. A first spring 310 is fitted onto the arc surface of the adjusting rod 309. Both ends of the first spring 310 are fixedly connected to the single-sided plate 308 and the adjusting rod 309, respectively. When workers need to adjust the position of the irregularly shaped frame 302, they first pull the adjusting rod 309. At this time, the first spring 310 is stretched until the arc surface of the adjusting rod 309 separates from the circular holes of the adjusting plate 301. Then, the workers... The operator can pull the irregularly shaped frame 302 to slide within the adjusting plate 301 until it reaches the desired position. Then, the operator can pull and release the adjusting rod 309. The rebound force of the first spring 310 causes the adjusting rod 309 to slide within the single-sided plate 308 until it inserts into the adjusting plate 301. This achieves the effect of adjusting the position of the irregularly shaped frame 302, enabling convenient and precise adjustment. It allows for quick and flexible adjustment of the frame's position according to the clamping requirements of different sized substrates, thereby changing the position of the clamping plate 306. This allows the device to accommodate various substrate sizes, effectively improving the platform's compatibility with different substrate sizes. A blocking plate 311 is fixedly connected to the arc surface of the adjusting rod 309.The size of the adjusting rod 309 is matched with the size of the circular hole in the adjusting plate 301. When the operator needs to adjust the position of the irregular frame 302, the operator first pulls the adjusting rod 309 to move the blocking plate 311 until the surface of the blocking plate 311 is in contact with the single-sided plate 308. At this time, the arc surface of the adjusting rod 309 is completely separated from the circular hole in the adjusting plate 301. This achieves the effect of preventing damage to the first spring 310 and avoids the situation where the operator pulls the adjusting rod 309 too far, causing the stress range of the first spring 310 to be exceeded, resulting in the loss of elasticity of the first spring 310 and making it difficult to use normally.
[0031] Reference Figure 4 and Figure 5As shown, specifically, the two heat dissipation devices 4 include two fixing brackets 41, which are fixedly connected to both sides of the positioning platform body 1. A dustproof net 42 is slidably connected inside the fixing bracket 41. Two handles 43 are fixedly connected to the surface of the dustproof net 42. Two fixing rods 44 are fixedly connected to both sides of the fixing bracket 41. A single-hole plate 45 is slidably connected to the arc surface of the fixing rod 44. A limit rod 46 is fixedly connected to one side of the single-hole plate 45. Two limit holes are opened on both sides of the fixing bracket 41. When the worker needs to disassemble the dustproof net 42 for cleaning, the first... First, the operator pulls the single-hole plate 45 to move the limiting rod 46 until the arc surface of the limiting rod 46 separates from the dustproof net 42. Then, the operator can pull the handle 43 to slide the dustproof net 42 within the fixed frame 41 until the dustproof net 42 separates from the surface of the fixed frame 41. At this point, the dustproof net 42 is disassembled, facilitating regular cleaning by the operator. This ensures the dustproof net 42 continues to provide dust protection, maintains the efficient operation of the device, protects the internal components of the positioning platform from dust intrusion, and thus improves the stability and lifespan of the equipment. The fixed rod 44 has a second spring 47 fitted on its arc surface. The two ends of the second spring 47 are fixedly connected to the fixed rod 44 and the single-hole plate 45, respectively. When the worker needs to install the dustproof net 42, firstly, the worker pulls the single-hole plate 45 to move the limiting rod 46 within the fixed frame 41. At this time, the second spring 47 is stretched until the limiting rod 46 no longer affects the movement of the dustproof net 42. Then, the worker can push the handle 43 to move the dustproof net 42 within the fixed frame 41 until the surface of the dustproof net 42 is completely in contact with the positioning platform body 1. Then, the worker can... When the single-hole plate 45 is released, the rebound force of the second spring 47 causes the single-hole plate 45 to slide on the arc surface of the fixed rod 44. The single-hole plate 45 drives the limiting rod 46 to move until the limiting rod 46 is inserted into the dustproof net 42. This achieves the effect of improving the stability of the limiting rod 46, so that the limiting rod 46 can always maintain a stable and tight state against the dustproof net 42 after installation, avoiding the limiting rod 46 from loosening and falling off due to equipment vibration or external force. This ensures that the dustproof net 42 is reliably fixed in position during use, effectively improving the stability and sealing of the dustproof net 42 after installation.
[0032] Working principle: When a worker needs to remove a pre-scribed substrate, they first pull the insertion rod 307 and slide it within the irregular frame 302 until the arc surface of the insertion rod 307 separates from the rotating plate 304. Then, the worker rotates the rotating plate 304 within the square groove of the irregular frame 302 until its surface separates from the clamping plate 306. The torque of the torsion spring 313 then drives the clamping plate 306 to rotate on the arc surface of the connecting rod 305. The clamping plate 306 moves the friction pad 312 until it no longer affects the substrate's movement, at which point the worker can remove the substrate. When the worker needs to adjust the position of the irregular frame 302, they pull the adjusting rod 309 to move the blocking plate 311 until its surface is in contact with the single-sided plate 308. At this point, the arc surface of the adjusting rod 309... The curved surface and the circular hole of the adjusting plate 301 are completely separated. At this time, the first spring 310 is stretched, and then the operator can pull the irregular frame 302 to slide inside the adjusting plate 301 until the irregular frame 302 moves to the appropriate position. Then the operator can pull and release the adjusting rod 309. At this time, the rebound force of the first spring 310 drives the adjusting rod 309 to slide inside the single-sided plate 308 until the adjusting rod 309 is inserted into the adjusting plate 301, achieving the effect of clamping the substrate. This avoids the situation where the substrate cannot be completely constrained by the placement plate alone. During laser scribing, the substrate may be displaced due to slight external force or vibration. As a result, when the substrate is laser scribing, the pattern or line of the laser scribing deviates from the preset position due to the certain displacement of the substrate position, causing damage to the substrate quality, making the substrate unusable, and wasting raw materials. This improves the practicality of the device.
[0033] When workers need to disassemble the dustproof net 42 for cleaning, they first pull the single-hole plate 45 to move the limiting rod 46 until the arc surface of the limiting rod 46 separates from the dustproof net 42. Then, workers can pull the handle 43 to slide the dustproof net 42 within the fixing frame 41 until the dustproof net 42 separates from the surface of the fixing frame 41. When workers need to install the dustproof net 42, they first pull the single-hole plate 45 to slide the limiting rod 46 within the fixing frame 41. At this time, the second spring 47 is stretched until the limiting rod 46 no longer affects the movement of the dustproof net 42. Then, workers can push the handle 43 to slide the dustproof net 42 within the fixing frame 41 until the dustproof net 42... The surface of the plate is completely in contact with the positioning platform body 1. Then, the operator can release the single-hole plate 45. At this time, the rebound force of the second spring 47 causes the single-hole plate 45 to slide on the arc surface of the fixing rod 44. The single-hole plate 45 drives the limiting rod 46 to move until the limiting rod 46 is inserted into the dustproof net 42. This achieves the effect of reducing the internal temperature of the positioning platform body, preventing the internal temperature of the positioning platform body from rising continuously during continuous operation. Continuous high-temperature operation will accelerate the wear and aging of the internal components of the positioning platform body, causing some internal parts of the platform body to reach their service life prematurely, resulting in increased replacement frequency of equipment parts and increased equipment procurement costs for enterprises, thus improving the practicality of the device.
