Intelligent placing rack for dust stick

Abstract

This utility model relates to the field of PCB manufacturing equipment, and more particularly to an intelligent placement rack for adhesive rollers, including a rolling platform and an arc-shaped receiving groove at one end. The top surface of the rolling platform has an adhesive section for holding adhesive paper. The top and bottom surfaces of the platform are inclined at an angle, with the end near the receiving groove being higher and the other end lower. This design prevents the adhesive roller from sticking to the adhesive paper when not in use, overcoming the drawback of traditional methods where forcibly dragging the roller can easily damage it. The inclined top surface creates a natural operating slope, allowing the adhesive roller to roll smoothly from high to low, utilizing gravity to assist in smooth dust removal, improving cleaning efficiency and reducing wrinkles. Positioning the receiving groove at a high position facilitates easy access and return of the adhesive roller, forming a closed-loop operation. Furthermore, the arc-shaped receiving groove fits the adhesive roller perfectly, covering most of the roller's surface, reducing debris adhesion and minimizing subsequent cleaning steps.

Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing equipment, and in particular to an intelligent placement rack for a dust roller. Background Technology In PCB manufacturing, due to the long production process and complex technology, various defects often appear during the visual inspection of finished boards. Among these, the most common is the problem of impurities under the solder mask. If the impurities are organic materials (such as lint, hair, or fibers), they will affect the appearance of the PCB board, and such defects are unacceptable to customers with strict requirements. If they are metallic materials (such as aluminum shavings, copper shavings, or iron shavings), they may cause short circuits in the solder pads, seriously affecting the soldering performance for customers, and even leading to customer complaints and compensation claims. Therefore, improving the problem of impurities under the solder mask is a key focus of continuous improvement for PCB manufacturers.

[0002] Impurities under the green ink are generated before green ink printing, and foreign objects may adhere to the board surface. Typically, PCB manufacturers provide a dust roller next to the screen printing machine as a cleaning tool. The procedure is as follows: before printing, the user cleans the dust roller on adhesive paper and then manually rolls it across the entire PCB surface; after cleaning, the dust roller is cleaned back and forth on the adhesive paper and then put back. However, this process has two core problems: First, if the dust roller is not used for a long time (e.g., more than 30 minutes), it will stick tightly to the adhesive paper, making it difficult to remove for the next use, and forcibly dragging it can damage the dust roller; second, the frequency of replacing the adhesive paper lacks a quantitative standard and relies on manual judgment. If it is not replaced in time after multiple uses, the adhesiveness will decrease or contaminants will accumulate, affecting the dust-adhesive effect and leading to impurities remaining under the green ink. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of the prior art.

[0004] The technical solution adopted by this utility model is to provide an intelligent placement rack for sticky rollers, including a rolling platform and a receiving groove provided at one end of the rolling platform. The rolling platform is provided with a dust-sticking part for placing sticky paper. The receiving groove is arc-shaped. The rolling platform includes a top surface and a bottom surface. The dust-sticking part is provided on the top surface. The top surface and the bottom surface of the rolling platform have an inclined angle. The end of the rolling platform near the receiving groove is higher than the other end away from the receiving groove.

[0005] The rolling platform supports the adhesive paper, providing an operating platform for the dust-sticking process, and a receiving slot holds the used adhesive roller. This physical isolation prevents the roller from sticking to the adhesive paper for extended periods when not in use, overcoming the problem of traditional placement methods where "forced dragging can easily damage the roller." Secondly, the inclined design of the top and bottom surfaces of the rolling platform creates a natural operating slope. During operation, the roller adheres to the adhesive paper and rolls from a high position to a low position, utilizing gravity to achieve a smooth "top-down" rolling motion, improving cleaning efficiency. Furthermore, the "top-down" motion allows the adhesive paper to adhere more evenly to the top surface, reducing wrinkles and making the rolling motion smoother. Meanwhile, the receiving slot is positioned at the higher end of the rolling platform's incline, allowing users to easily retrieve the sticky roller from the higher slot before starting the initial cleaning process using the aforementioned "top-to-bottom" method. After cleaning, the roller can be pushed back into the receiving slot, creating a closed-loop operation that reduces additional steps and is convenient and quick. Furthermore, the receiving slot is designed with an arc shape to fit the cylindrical roller body, effectively covering most of the roller's surface when placed inside, reducing the adhesion of dust, hair, and other debris from the air, minimizing subsequent cleaning steps, and improving cleaning efficiency.

[0006] Furthermore, by designing the width of the receiving slot to be equal to the width of the rolling platform, the same placement rack can be compatible with multiple sizes of adhesive rollers, adapting to PCB production lines of different specifications. This eliminates the need to customize special placement racks for rollers of different sizes, reducing equipment management costs.

[0007] Furthermore, a support rod is located on the top surface of the rolling platform near the receiving slot. This support rod supports the handle of the sticky roller. When the sticky roller is placed in the receiving slot, the handle naturally rests on the support rod, completely isolating it from contact with the sticky paper. This prevents the handle from pressing down on the sticky paper during placement, which could cause contamination or wrinkles and affect the subsequent sticking effect. It also prevents the handle from contacting the sticky paper and adhering with residue, keeping the handle clean and improving user comfort. Secondly, the length of the support rod is equal to the width of the rolling platform, forming a full-coverage support. When picking up or placing the sticky roller, there is no need to deliberately adjust the handle position. Whether the sticky roller is placed in the center, slightly to the left, or slightly to the right in the receiving slot, the handle receives uniform support, avoiding problems such as handle tilting or sticky roller slippage caused by support point misalignment, reducing operation and adjustment time. Finally, the raised handle position makes it easier for users to grip. In addition, the top surface of the support rod is designed with an arc shape. Regardless of whether the handle cross-section is smooth or curved, the arc top surface can provide adaptive and stable support between points, between points and surfaces, or between surfaces, avoiding the limitation of only adapting to a single handle shape and improving the versatility of the device.

[0008] Furthermore, the bottom surface of the rolling platform is equipped with anti-slip pads. When the user operates the sticky roller to roll on the inclined platform, the lateral or longitudinal forces generated are effectively offset by the anti-slip pads. This not only prevents the entire placement rack from sliding and shifting, but also reduces the risk of accidental wrinkling or displacement of the sticky paper caused by equipment movement. This ensures that the sticky paper in the sticky section is always laid flat, ensuring accurate positioning of the sticky operation and reducing the risk of operational errors.

[0009] Furthermore, the adhesive section includes a fixing component and a receiving component. The fixing component is used to secure the adhesive paper, and the receiving component is used to hold the adhesive paper. The fixing component surrounds the receiving component to form a "ring-shaped fixing band," firmly fixing the edge of the adhesive paper within the receiving component. This ensures that the adhesive paper remains flat and fixed even when tilted, while also preventing the adhesive paper from sliding, wrinkling, or shifting due to external forces during operation. When the adhesive roller rolls back and forth on the adhesive section for cleaning, the adhesive paper will not slide or create local wrinkles or gaps, ensuring full contact between the adhesive roller and the adhesive paper, improving the adsorption efficiency of impurities under the green oil, and maintaining the uniformity of the adhesive effect.

[0010] Preferably, the fastener is an adhesive tape, and the receiving part is the top surface space of the rolling platform in the middle of the rear of the adhesive tape, and the adhesive tape adheres the dust paper to the top surface of the rolling platform.

[0011] Preferably, the receiving part is a groove formed on the top surface of the rolling platform, and the fixing part is the side wall of the groove. The side wall and bottom surface of the groove together constrain the movement range of the adhesive paper, which simplifies the installation or removal process of the adhesive paper and improves the operating efficiency.

[0012] Preferably, the receiving part is a groove formed on the top surface of the rolling platform, and the fixing member is an adhesive strip surrounding the groove. The two work together to prevent the sticky paper from sliding.

[0013] Furthermore, the receiving slot includes a through hole and an infrared counter. The infrared counter is installed on the through hole. When the sticky roller is picked up and removed from or returned to the receiving slot, the number of times the infrared beam is blocked or connected is recorded, corresponding to the number of times a single sticky paper is used for sticking. At the same time, the through hole is opened on the side of the receiving slot to ensure that the infrared light is only emitted or received inside the receiving slot, avoiding counting disorder caused by accidental touches due to external light, dust or personnel movement. With the arc-shaped structure of the receiving slot, the infrared beam accurately covers the entry and exit path of the sticky roller, improving the reliability of counting.

[0014] Furthermore, the rolling platform also includes a counter display and a buzzer on the top surface. The infrared counter is linked to the counter display and buzzer. When the number of uses reaches a preset threshold, the buzzer automatically triggers an alarm sound to remind employees to replace the adhesive paper in time. This avoids the decline in the adhesive effect due to overuse of the adhesive paper, such as decreased stickiness and accumulation of contaminants, reducing the quality risks caused by forgetting to replace it. At the same time, the counter display visualizes the number of uses in real time, allowing users to intuitively grasp the cumulative amount of adhesive paper used, solving the uncertainty problem of relying on manual memory or subjective judgment of when to replace it. Secondly, placing the counter display and buzzer on the periphery of the adhesive section does not interfere with the rolling cleaning operation of the adhesive roller and adhesive paper, while ensuring that users can naturally see the display or hear the reminder during operation, forming a complete intelligent closed loop of "operation-counting-reminder-replacement", improving the automation and standardization level of the overall process.

[0015] Preferably, the radius of the receiving groove is 40mm-100mm. Its size design ensures that it covers the radius specifications of the dust-adhesive rollers commonly used in PCB production, so that they form a "face-to-face" contact with the receiving groove body. This avoids the problem of the roller body swaying due to being too small or the groove body being unable to accommodate it due to being too large, thereby improving the placement stability.

[0016] Preferably, the angle between the top and bottom surfaces of the rolling platform is 3°–30°, ensuring that the adhesive roller can naturally roll from high to low under gravity, achieving a smooth "top-to-bottom" dust-rolling action. If the angle is too small, the gravity-assisted effect is weak; if the angle is too large, the roller is prone to shifting due to gravity during the replacement of the adhesive paper, affecting work efficiency.

[0017] Furthermore, the entire placement rack is made of stainless steel. The high strength of stainless steel ensures that the rack remains structurally stable during frequent operations. Secondly, the stainless steel surface is polished to create a low-friction, easy-to-clean surface, which reduces the adhesion of the dust roller to the receiving slot or support rod during loading and unloading. Moreover, stainless steel has excellent corrosion resistance, resisting the corrosion of acids, alkalis, solvents, and other chemicals that may be encountered in the PCB production environment. This avoids the rusting and embrittlement problems caused by corrosion of traditional metal or plastic materials, significantly extending the service life of the equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: the top surface of the rolling platform is provided with a dust-adhesive part for placing the dust-adhesive paper, and one end is provided with an arc-shaped receiving groove for placing the dust-adhesive roller. The top and bottom surfaces form an inclined angle, and gravity-assisted rolling is achieved through a natural slope from high to low. This not only avoids the dust-adhesive roller from sticking to the dust-adhesive paper when it is stationary for a long time, but also improves efficiency through the closed-loop operation of picking up the dust-adhesive roller → rolling for cleaning → pushing back into the receiving groove. The width of the receiving groove is equal to the width of the platform, which can accommodate multiple sizes of dust-adhesive rollers. The arc design makes the surface of the roller body covered, reducing the adhesion of dust and hair in the air.

[0019] Secondly, a support rod of equal width is set at the top of the rolling platform, which completely isolates the handle from contact with the adhesive paper when the handle is overlapped, avoiding contamination or wrinkles; the top surface of the support rod is arc-shaped to adapt to different handle shapes, achieving full coverage and stable support; the anti-slip pads on the bottom surface counteract the lateral / longitudinal forces during operation, preventing the placement rack from sliding and causing the adhesive paper to shift or wrinkle, ensuring accurate positioning during the adhesive application operation.

[0020] Furthermore, the adhesive section, combined with the receiving section via a fixing component, ensures that the adhesive paper remains flat and fixed even when tilted, preventing slippage, wrinkles, or displacement and maintaining uniform adhesive effect. Simultaneously, an infrared counter built into the side opening of the receiving slot records the number of times the adhesive roller enters and exits, corresponding to the number of times a single sheet of adhesive paper is used. This is linked to the top-mounted counter display and buzzer, triggering an audible alert based on a preset threshold. Real-time visual display of usage eliminates the uncertainty of manual judgment regarding replacement timing and avoids quality risks caused by adhesive attenuation or contaminant accumulation.

[0021] In addition, the radius of the receiving tank is designed to be 40mm-100mm, covering the mainstream specifications of the sticky dust roller; the tilt angle is 3°-30° to balance the gravity assistance effect and operational stability; the whole is made of stainless steel, with high strength, corrosion resistance, and low friction coefficient surface, resisting the corrosion of acid and alkali solvents in PCB production lines, extending equipment life and reducing maintenance costs.

Detailed Implementation

[0034] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0035] Example 1 like Figure 1 and Figure 2 As shown, this embodiment 1 provides an intelligent placement rack for sticky rollers, including a rolling platform 100 and a receiving groove 200 disposed at one end of the rolling platform 100. The side of the receiving groove 200 is arc-shaped with a radius of 60mm in diameter. The width of the receiving groove 200 is equal to the width of the rolling platform 100. The rolling platform 100 is provided with a dust-adhesive part 300 for placing sticky paper. The rolling platform 100 includes a top surface 110 and a bottom surface 120. The dust-adhesive part 300 is disposed on the top surface 110. Figure 3 and Figure 4 As shown, the top surface 110 and bottom surface 120 of the rolling platform 100 have an inclined angle, and the included angle between the top surface 110 and bottom surface 120 is 3°. The end of the rolling platform 100 near the receiving groove 200 is higher than the other end away from the receiving groove 200. The whole is made of stainless steel.

[0036] The top surface 110 of the rolling platform 100, near the end of the receiving groove 200, is provided with a support rod 111. The top surface of the support rod 111 is arc-shaped, further combining... Figure 5 As shown, the length of the support rod 111 is equal to the width of the rolling platform 100, such as... Figure 6 As shown, the bottom surface 120 of the rolling platform 100 is provided with anti-slip pads 121.

The rolling platform 100 also includes a counting display 112 and a buzzer 113 on the top surface 110. The counting display 112 and the buzzer 113 are located around the dust-adhesive part 300. The infrared counter 220 is connected to the counting display 112 and the buzzer 113. like Figure 9 and Figure 10 As shown, when the sticky roller is picked up and removed from the receiving tank 200 or put back into the receiving tank 200, the number of times the infrared beam of the infrared counter 220 is blocked or connected is recorded, corresponding to the number of times a single sticky paper is used for sticking. At the same time, the through hole 210 is opened on the side of the receiving tank 200 to ensure that the infrared light is only emitted or received inside the receiving tank, avoiding counting disorder caused by accidental touch due to external light, dust or personnel movement. With the arc-shaped structure of the receiving tank 200, the infrared beam accurately covers the entry and exit path of the sticky roller, improving the counting reliability.

[0039] When the number of uses reaches a preset threshold, the buzzer 113 automatically triggers a prompt sound to remind employees to replace the adhesive paper in time. This prevents the adhesive paper from losing its stickiness due to overuse, such as decreased stickiness or accumulation of contaminants, and reduces the quality risks caused by forgetting to replace it. At the same time, the counter display 112 visualizes the number of uses in real time, allowing users to intuitively grasp the cumulative amount of adhesive paper used, solving the uncertainty problem of relying on manual memory or subjective judgment when to replace it. Secondly, placing the counter display 112 and the buzzer 113 around the adhesive section 300 does not interfere with the rolling cleaning operation of the adhesive roller and adhesive paper, while ensuring that users can naturally see the display or hear the reminder during operation, forming a complete intelligent closed loop of "operation-counting-reminder-replacement".

The side of the receiving groove 200 is arc-shaped with a radius of 60mm in diameter. The width of the receiving groove 200 is equal to the width of the rolling platform 100. The rolling platform 100 is provided with a dust-adhesive part 300 for placing sticky paper. The rolling platform 100 includes a top surface 110 and a bottom surface 120. The dust-adhesive part 300 is provided on the top surface 110. The top surface (110) and the bottom surface 120 of the rolling platform 100 have an inclined angle. The included angle between the top surface 110 and the bottom surface 120 is 3°. The end of the rolling platform 100 near the receiving groove 200 is higher than the other end away from the receiving groove 200. The whole is made of stainless steel.

[0041] A support rod 111 is provided on the top surface 110 of the rolling platform 100 near the receiving groove 200. The top surface of the support rod 111 is arc-shaped, and the length of the support rod 111 is equal to the width of the rolling platform 100.

[0042] The adhesive part 300 includes a fixing member 310 and a receiving part 320. The fixing member 310 is used to fix the adhesive paper, and the receiving part 320 is used to place the adhesive paper. The fixing member 310 surrounds the receiving part 320.
