Description

Technical Field

[0001] This utility model relates to the field of circuit board font printing technology, specifically, to a circuit board font alignment device. Background Technology

[0002] A circuit board text alignment device is a device used to ensure the precise alignment of text, markings and other elements on a circuit board. This device is commonly used in the production process to ensure that the characters or graphics on the circuit board are consistent with the design drawings, avoiding errors or defects caused by inaccurate alignment. This is crucial for improving production efficiency and ensuring product quality, and is widely used in the electronics manufacturing industry.

[0003] In the prior art, traditional circuit board font printing positioning components generally use corner positioning strips to position the circuit board. In this way, the corners of the circuit board are positioned to ensure that the font is aligned with the position of the circuit board during the printing process. However, this positioning method has some significant drawbacks. First, when printing circuit boards of different sizes, it is usually necessary to replace the positioning frame or positioning corner strip of the corresponding size. This not only increases the complexity of the operation in the production process, but also leads to the extension of equipment change and adjustment time. The frequent need to replace positioning components affects production efficiency and increases production costs. In addition, the traditional corner positioning strip method may not be able to fully take into account the diversity of different types of circuit boards, resulting in positioning errors, which in turn affect the text printing quality of the circuit board. Therefore, those skilled in the art provide a circuit board font alignment device to solve the problems mentioned in the background art. Utility Model Content

[0028] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the placement component 1 includes a placement base plate 101.

The multiple movable slots 102 ensure that the circuit board body 6 can be placed stably and is stably clamped and positioned by four adjustment mechanisms 4 and twelve positioning clamping components 5. The main function of the placement component 1 is to provide a stable and adjustable placement platform for the circuit board, so that the circuit board remains horizontal during the printing process and reduces printing deviations caused by inaccurate positioning. The design of this structure allows the placement process to quickly adapt to circuit boards of different sizes, improving the flexibility and efficiency of the production process, especially when multiple sizes of circuit boards need to be changed quickly.

The main support column 201 is located at the center of the lower end of the placement base plate 101, while the four secondary support columns 202 surround the lower edge of the main support column 201. The four secondary support columns 202, together with the main support column 201, can evenly distribute the weight, ensuring that the placement assembly 1 will not tilt or become unstable during use, thus improving the stability of the entire device. In addition, the support assembly 2 is connected to the secondary support columns 202 through the support base plate 203, which strengthens the support and effectively prevents vibration or uneven pressure during operation from affecting the circuit board body 6.

[0032] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the drive assembly 3 includes a drive motor 301, which is disposed at the lower end of the support substrate 203. The upper rotating end of the drive motor 301 is fixedly connected to the center of the lower end of the support substrate 203. A conductive slip ring 302 is fixedly connected to the center of the upper end of the drive motor 301 near the edge, and the upper rotating end of the conductive slip ring 302 is fixedly connected to the center of the lower end of the support substrate 203 near the edge.

[0033] The drive assembly 3 drives the placement assembly 1 to rotate via the drive motor 301. The drive motor 301 is fixed to the lower end of the support substrate 203, and its rotating end is connected to the center of the lower end of the support substrate 203 via a conductive slip ring 302.

The two guide rails 403 are fixedly connected to both sides of the lower end of the placement base 101 near the lead screw 405. A first bearing 404 is fixedly sleeved inside the center of each of the two support lugs 402. A lead screw 405 is fixedly sleeved inside each of the two first bearings 404. One end of the lead screw 405 is fixedly connected to the rotating end of the stepper motor 401. Guide sleeves 406 are slidably fitted on the lower outer sides of the two guide rails 403.

An internal threaded sleeve 408 is fixedly connected to the center of the lower end of the first connecting plate 407, and the internal threaded sleeve 408 is threaded onto the outside of the lead screw 405. A second connecting plate 409 is fixedly connected to the upper center of the side of the two guide sleeves 406 that is far apart from each other. A support base 4010 is fixedly connected to the center of the upper side of the two second connecting plates 409 that is far apart from each other and the center of the upper end of the first connecting plate 407. A connecting shaft 4011 is fixedly connected to the center of the upper end of the three support bases 4010.

[0035] The adjustment mechanism 4 consists of a stepper motor 401, two support lugs 402, and two guide rails 403. The stepper motor 401 drives the lead screw 405 to rotate. When the lead screw 405 rotates, it synchronously drives the first connecting plate 407, which is fixedly connected to the internal threaded sleeve 408, to move. While the first connecting plate 407 moves horizontally, it also drives the two guide sleeves 406, which are fixedly connected to the second connecting plates 409, to move horizontally. In turn, the first connecting plate 407 and the two second connecting plates 409 drive the twelve support seats 4010 to move. This process drives the twelve positioning clamping components 5 on the adjustment mechanism 4 to make precise adjustments through the rotation of the lead screw 405. The working principle of the adjustment mechanism 4 realizes high-precision and fast positioning adjustment, and can accurately control the movement of the positioning clamping components 5 to ensure that the circuit board body 6 achieves the best alignment effect during the clamping process. The design of the adjustment mechanism 4 ensures that the device can make fine adjustments according to the size of the circuit board, improving the automation and adaptability of the equipment.

[0036] As one implementation method in this embodiment, please refer to Figure 6 As shown, twelve support seats 4010 are slidably sleeved inside twelve movable slots 102. Each of the twelve positioning and clamping components 5 includes a second bearing 501. The inner rings of the twelve second bearings 501 are fixedly sleeved on the outer side of the twelve connecting shafts 4011, and the outer rings of the twelve second bearings 501 are fixedly sleeved with rubber positioning wheels 502. The twelve rubber positioning wheels 502 are in groups of three and are respectively attached to the four side walls of the circuit board body 6.

[0037] The positioning and clamping assembly 5 consists of a second bearing 501 and rubber positioning wheels 502. The rubber positioning wheels 502 are attached to the four side walls of the circuit board body 6 and are fixed by twelve support seats 4010. Each rubber wheel is connected to the adjustment mechanism 4 through a connecting shaft 4011 to ensure that the circuit board body 6 can be accurately clamped and positioned. During positioning, the positioning and clamping assembly 5 not only provides precise mechanical support, but also avoids damage to the surface of the circuit board due to the softness of the rubber wheels, thereby improving the safety and positioning accuracy of the circuit board. This design greatly improves the reliability of the equipment in efficient and precise production.

[0038] Working Principle: The placement component 1 consists of a placement base 101 with multiple movable slots 102 internally. These slots ensure the circuit board body 6 can be stably placed and is stably clamped and positioned by four adjustment mechanisms 4 and twelve positioning clamping components 5. The main function of the placement component 1 is to provide a stable and adjustable placement platform for the circuit board, keeping it level during printing and reducing printing deviations caused by inaccurate positioning. This design allows for rapid adaptation to circuit boards of different sizes, improving flexibility and efficiency in the production process, especially when multiple sizes of circuit boards need to be quickly replaced. Component 2 provides stable support for the placement component 1 through the main support column 201 and the secondary support columns 202. The main support column 201 is located at the center of the lower end of the placement base plate 101, while the four secondary support columns 202 surround the lower edge of the main support column 201. The four secondary support columns 202, together with the main support column 201, can evenly distribute the weight, ensuring that the placement component 1 will not tilt or become unstable during use, thus improving the stability of the entire device. In addition, the support component 2 is connected to the secondary support columns 202 through the support base plate 203, which strengthens the support and effectively prevents vibration or uneven pressure during operation from affecting the circuit board body 6.

[0039] The driving component 3 drives the placement component 1 to rotate via the driving motor 301. The driving motor 301 is fixed to the lower end of the support substrate 203, and its rotating end is connected to the center of the lower end of the support substrate 203 via a conductive slip ring 302. Driven by the driving motor 301, the entire support component 2 and placement component 1 can rotate, thereby adjusting the positioning angle of the circuit board body 6 to adapt to different printing requirements. This driving method enables the device to have an automatic adjustment function, improves the automation level of the operation process, avoids errors caused by manual operation, and improves production efficiency and accuracy. The adjustment mechanism 4 consists of a stepper motor 401, two support lugs 402, and two guide rails 403, etc. The stepper motor 401 drives the lead screw 405 to rotate. When the lead screw 405 rotates, it will move in tandem with the lead screw 405. The first connecting plate 407, which is fixedly connected to the internal threaded sleeve 408, moves horizontally. While the first connecting plate 407 moves horizontally, it also drives the two guide sleeves 406, which are fixedly connected to the second connecting plates 409, to move horizontally. In turn, the first connecting plate 407 and the two second connecting plates 409 drive the twelve support seats 4010 to move. This process is precisely adjusted by rotating the lead screw 405 to drive the twelve positioning clamping components 5 on the adjustment mechanism 4. The working principle of the adjustment mechanism 4 realizes high-precision and fast positioning adjustment, and can accurately control the movement of the positioning clamping components 5 to ensure that the circuit board body 6 achieves the best alignment effect during the clamping process. The design of the adjustment mechanism 4 ensures that the device can be finely adjusted according to the size of the circuit board, improving the automation and adaptability of the equipment.

[0040] The positioning and clamping assembly 5 consists of a second bearing 501 and rubber positioning wheels 502. The rubber positioning wheels 502 are attached to the four side walls of the circuit board body 6 and are fixed by twelve support seats 4010. Each rubber wheel is connected to the adjustment mechanism 4 through a connecting shaft 4011 to ensure that the circuit board body 6 can be accurately clamped and positioned. During positioning, the positioning and clamping assembly 5 not only provides precise mechanical support, but also avoids damage to the surface of the circuit board due to the softness of the rubber wheels, thereby improving the safety and positioning accuracy of the circuit board. This design greatly improves the reliability of the equipment in efficient and precise production.
