Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for textile machinery assembly, specifically a Jacquard circuit board rapid positioning device. Background Technology

[0002] The jacquard circuit board is the core control component of the jacquard drive unit, integrating a large number of electronic components and interfaces. Its installation accuracy directly affects the pattern weaving accuracy of the warp knitting machine. During the assembly of the jacquard drive unit, the jacquard circuit board must be precisely positioned and fixed in the guide bar base or drive housing to ensure that the interfaces on the circuit board accurately connect with the piezoelectric ceramic elements, sensors, and other components.

[0003] Current assembly methods mostly rely on manual hand-held positioning, adjusting the alignment of the circuit board mounting holes with the base screw holes. This method has the following problems: First, positioning efficiency is low, requiring repeated manual adjustments, and positioning a single circuit board is typically time-consuming, making it difficult to meet the needs of mass production. Second, positioning accuracy is poor; manual operation is prone to circuit board misalignment due to hand tremors, causing interface misalignment and affecting the stability of drive signal transmission. These problems are particularly prominent in the large-scale production of Jacquard drive devices, restricting assembly efficiency and product quality stability. Utility Model Content

[0004] The purpose of this invention is to provide a Jacquard circuit board rapid positioning device to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A Jacquard circuit board rapid positioning device includes a fixed plate. The top surface of the fixed plate has a pair of non-communicating first cavities. Each of the first cavities has an adjusting strip that slides along the wide side of the first cavity. The top surface of each adjusting strip has a second cavity, and each second cavity has a pair of adjusting blocks that slide along the long side of the second cavity. A first positioning post is installed at the center of the top surface of each adjusting block, and a second positioning post is installed on the top surface of the first positioning post. The diameter of the first positioning post is larger than the diameter of the second positioning post. The fixed plate has a through hole at its center, and a push rod slides within the through hole. The push rod is elastically connected to the bottom surface of the fixed plate. Through the sliding cooperation of the adjusting strip with the first cavity and the adjusting block with the second cavity, it can flexibly adapt to the fixed opening positions of different specifications of Jacquard circuit boards and back covers, eliminating the need to customize positioning devices for different models and reducing equipment costs. The diameter difference design of the first positioning post and the second positioning post can respectively adapt to the fixed openings of the back cover and circuit board and the threaded holes of the comb, realizing the positioning of multiple components, avoiding misalignment of multiple components, and improving positioning accuracy.

[0006] Furthermore, a first limiting groove is provided on the wide side of the first cavity, and a first limiting block is installed on a pair of opposite sides of the adjusting strip. The first limiting block slides in the first limiting groove. The cooperation between the first limiting block and the first limiting groove can ensure that the adjusting strip always slides stably along the preset direction, prevent the adjusting strip from being misaligned during the adjustment process, and prevent the positioning post from deviating, thereby further ensuring positioning accuracy.

[0007] Furthermore, a second limiting groove is provided on the long side of the second cavity, and a second limiting block is installed on a pair of opposite sides of the adjusting block. The second limiting block slides in the second limiting groove. The cooperation between the second limiting block and the second limiting groove can stabilize the sliding process of the adjusting block, prevent the adjusting block from shifting and causing the first positioning post and the second positioning post to be inaccurate in position, and at the same time prevent the adjusting block from falling off, thereby improving the stability of the device.

[0008] Furthermore, anti-slip rubber pads are installed on the outer sides of both the first and second limiting blocks. The anti-slip rubber pads can lock the adjusted position through friction, eliminating the need for additional fixing structures and simplifying the operation process. At the same time, they prevent the positioning pins from shifting during assembly, ensuring that the alignment of multiple parts is always accurate and reducing the probability of rework.

[0009] Furthermore, a connecting plate is installed at the center of the bottom end of the top rod. A spring is connected between the top surface of the connecting plate and the bottom surface of the fixed plate. The spring and the top rod are arranged parallel to each other. The top rod is located inside the inner ring of the spring. The elastic structure of the spring enables the top rod to automatically reset without manual pulling, simplifying the operation steps. The design of the top rod being located inside the spring can prevent the spring from shifting when deformed, ensuring that the top rod always slides in the vertical direction, ensuring uniform force when multiple parts are in contact, and preventing component deformation.

[0010] Furthermore, the top edges of both the first and second positioning posts are rounded. The rounded corner design reduces the difficulty of aligning the parts into the positioning posts, speeds up the assembly process, and prevents the edges of the positioning posts from scratching the circuit board, the back cover surface, or the comb thread holes, thus protecting the integrity of the parts and reducing the defect rate.

[0011] Furthermore, a rubber ring is installed on the outer side of the first positioning post. The rubber ring can eliminate the gap between the opening and the positioning post, avoid the alignment deviation caused by the shaking of the component, and further improve the positioning accuracy. At the same time, the friction can help fix the position of the component, reduce the force required for manual pressing and fixation, and reduce operator fatigue.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This Jacquard circuit board rapid positioning device, through the sliding cooperation and limiting structure of the adjusting strip and adjusting block, can flexibly adapt to different models of Jacquard circuit boards and supporting components, reducing the investment in special equipment; and by utilizing the diameter difference of the positioning column, the rubber ring design and the elastic reset structure of the top rod, it can achieve rapid and accurate positioning and bonding of the back cover, circuit board and comb, greatly shortening the positioning time of a single circuit board, while avoiding alignment deviation caused by manual operation shaking, ensuring stable transmission of drive signals, and ultimately improving the assembly efficiency and product quality stability of the Jacquard drive device in mass production.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5This utility model provides a technical solution: a Jacquard circuit board quick positioning device, including a fixed plate 1. The top surface of the fixed plate 1 has a pair of non-communicating first cavities 2. Each pair of first cavities 2 has an adjusting strip 3 inside, and the adjusting strip 3 slides along the wide side of the first cavity 2. The top surface of each adjusting strip 3 has a second cavity, and each second cavity has a pair of adjusting blocks 4 inside, which slide along the long side of the second cavity. A first positioning post 7 is installed at the center of the top surface of each adjusting block 4. A second positioning post 8 is installed on the top surface. The diameter of the first positioning post 7 is larger than the diameter of the second positioning post 8. A through hole 5 is opened at the center of the fixed plate 1. A push rod 6 slides in the through hole 5. The push rod 6 is elastically connected to the bottom surface of the fixed plate 1. For example, a piezoelectric jacquard and a piezoelectric jacquard driver for the jacquard are disclosed in Chinese Patent Publication No. CN220364687U. Before use, according to the fixed opening position of the jacquard circuit board 46 and the back cover 42, the adjusting strip 3 is pushed to slide along the wide side of the first cavity 2 to adjust the adjusting strip. 3. Position the adjusting block 4 laterally on the fixed plate 1; then push the adjusting block 4 to slide along the long side of the second cavity on the top surface of the adjusting strip 3, and adjust the longitudinal position of the adjusting block 4 so that the first positioning post 7 and the second positioning post 8 installed on the adjusting block 4 are completely aligned with the position of the fixing opening. During assembly, first place the back cover 42 on the fixed plate 1, and let the first positioning post 7 pass through the fixing opening of the back cover 42; then place the circuit board 46 on the back cover 42, and let the first positioning post 7 pass through the fixing opening of the circuit board 46 simultaneously; finally, place the comb 44 on the circuit board. On 46, because the diameter of the second positioning post 8 is smaller than that of the first positioning post 7, and the threaded hole of the comb 44 corresponds to the position of the fixing opening, the second positioning post 8 can slide into the threaded hole of the comb 44 to achieve initial positioning of the three. Then, the connecting plate 13 is pressed, and the push rod 6 slides along the through hole 5 and presses the back cover 42, so that the circuit board 46 and the comb 44 are tightly attached. Then, the back cover 42, the circuit board 46 and the comb 44 are fixed with a clamp. Finally, the device is removed, and the back cover 42, the circuit board 46 and the comb 44 can be fixed with screws.

[0017] As an embodiment of this utility model, the first cavity 2 is further provided with a first limiting groove 11 on the wide side, and a first limiting block 12 is installed on a pair of opposite sides of the adjusting strip 3. The first limiting block 12 slides in the first limiting groove 11. When the position of the adjusting strip 3 is adjusted, the first limiting block 12 on the side of the adjusting strip 3 will slide synchronously along the first limiting groove 11 on the wide side of the first cavity 2, restricting the sliding direction of the adjusting strip 3 and preventing the adjusting strip 3 from coming out of the first cavity 2 or from shifting laterally.

[0018] As an embodiment of this utility model, the second cavity is further provided with a second limiting groove 9 on the long side, and a pair of opposite sides of the adjusting block 4 are each provided with a second limiting block 10. The second limiting block 10 slides in the second limiting groove 9. When the adjusting block 4 is pushed to slide along the long side of the second cavity, the second limiting block 10 on the side of the adjusting block 4 will slide synchronously along the second limiting groove 9 on the long side of the second cavity, constraining the sliding trajectory of the adjusting block 4 and preventing the adjusting block 4 from coming out of the second cavity or deviating from the longitudinal sliding direction.

[0019] As an embodiment of this utility model, anti-slip rubber pads are further installed on the outer sides of the first limiting block 12 and the second limiting block 10. When adjusting the adjusting strip 3 or the adjusting block 4, the anti-slip rubber pads on the outer sides of the first limiting block 12 and the second limiting block 10 will be in close contact with the inner walls of the first limiting groove 11 and the second limiting groove 9, increasing the friction. After adjustment, the friction can fix the position of the adjusting strip 3 and the adjusting block 4, preventing them from sliding due to vibration or slight contact during subsequent assembly.

[0020] As an embodiment of this utility model, a connecting plate 13 is further installed at the center of the bottom end of the top rod 6. A spring 14 is connected between the top surface of the connecting plate 13 and the bottom surface of the fixing plate 1. The spring 14 and the top rod 6 are arranged in parallel, and the top rod 6 is located in the inner ring of the spring 14. When assembling, the connecting plate 13 is pressed, and the connecting plate 13 drives the top rod 6 to slide upward along the through hole 5. The top end of the top rod 6 pushes the comb 44, the circuit board 46, and the back cover 42 to fit tightly together. At the same time, the connecting plate 13 compresses the spring 14. After the fit is completed, the connecting plate 13 is released, the spring 14 returns to its deformation, and the connecting plate 13 and the top rod 6 are reset, which facilitates the removal of the device for subsequent screw fixing operations.

[0021] As an embodiment of this utility model, the top edges of the first positioning post 7 and the second positioning post 8 are both set with rounded corners. When the back cover 42 and the circuit board 46 are fitted into the first positioning post 7, or the comb 44 is fitted into the second positioning post 8, the rounded corners of the top surface of the positioning post will guide the components to quickly align with the opening, avoiding the components from getting stuck or scratched due to the right angle collision between the opening and the right angle of the top edge of the positioning post.

[0022] As an embodiment of this utility model, a rubber ring is further installed on the outer side of the first positioning post 7. After the back cover 42 and the circuit board 46 are fitted into the first positioning post 7, the rubber ring on the outer side of the first positioning post 7 will fit tightly against the inner wall of the opening, filling the gap between the opening and the positioning post, while increasing the friction force and preventing the parts from rotating or slightly shifting during the assembly process.

[0023] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
