Description

Technical Field

[0001] This utility model relates to the field of engine cylinder heads, and in particular to a device for removing plugging adhesive. Background Technology

[0002] In modern engine manufacturing, cylinder head production is a crucial step. As one of the core components of an engine, the quality and performance of the cylinder head directly affect the overall engine's operating efficiency and reliability. The material handling station is a key step in the cylinder head production process, its main task being to perform various machining and processing operations on the cylinder head to ensure it meets design requirements and quality standards.

[0003] At the cylinder head cutting station, operators need to manually remove excess glue from the cylinder heads. This process removes any remaining glue from the cylinder heads to ensure a clean and smooth surface. Traditional methods typically involve wiping or scraping, which, while effective to some extent, have several drawbacks.

[0004] First, traditional glue removal methods are inefficient. Due to the limitations of manual operation, operators need to spend a lot of time and energy to complete the glue removal work, which not only increases production costs but may also lead to a decrease in production efficiency. In modern manufacturing, time is money, and reduced production efficiency means a weakening of a company's competitiveness.

[0005] Secondly, traditional adhesive removal methods may damage the surface being cleaned. Wiping or scraping requires the operator to apply force, which can scratch or abrade the cylinder head surface, affecting its quality and appearance. As a crucial engine component, the cylinder head's surface quality directly impacts the engine's sealing and reliability; any surface damage can lead to serious consequences.

[0006] Furthermore, traditional glue removal methods pose potential health hazards to operators. During the removal process, operators may come into contact with residual glue and chemical solvents, which may contain harmful components. Long-term exposure can damage the operator's health. Additionally, manual glue removal requires maintaining a specific posture for extended periods, which can lead to muscle fatigue and occupational diseases.

[0007] Therefore, it is particularly important to develop an efficient, safe, and non-damaging method for removing adhesive from the surface being cleaned. Utility Model Content

[0027] 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.

[0028] This utility model discloses a device for removing excess white glue residue from screw plug holes, aiming to solve the problems of low efficiency, potential damage to the cleaned surface, and potential health hazards to operators associated with traditional glue removal methods. Through the design of an automated glue removal device, efficient, safe, and non-damaging glue removal is achieved.

[0029] This utility model's device for removing glue buildup from screws includes components such as a servo motor 1, a coupling 2, a slip ring 3, a brush 4, a distance fixing plate 5, and an air pipe connector 6. The workpiece flows from the roller conveyor to a designated area and is positioned by a cylinder. A positioning signal triggers the positioning clamp above the roller conveyor to descend. The servo motor 1 is connected to the slip ring 3 via the coupling 2. The slip ring 3 rotates and scrapes the white glue on the workpiece through the PBT (polybutylene terephthalate) brush 4. Simultaneously, air is blown through the 3mm diameter center hole of the brush 4, using 4 bar of air pressure to clean the white glue removed by the brush 4.

[0030] The distance fixing plate 5 is located horizontally in the middle of the device. It is rectangular and made of metal. It is used to fix the overall structure of the device and ensure the relative position stability between the components. It can also be used to adjust the distance between the brush 4 and the work object.

[0031] Two servo motors 1 are symmetrically inverted and mounted above the fixed plate 5. The motor housing has heat dissipation grooves, and the motor side has power and control cable interfaces. The servo motor 1 contains a stator and a rotor. The rotor is precisely controlled by an encoder, which provides the power source to drive the coupling 2, slip ring 3, and brush 4 to rotate, thereby removing the plugging adhesive from the screw.

[0032] Coupling 2 is installed between the servo motor 1 and the distance fixing plate 5, connecting the motor output shaft and the slip ring 3. It is cylindrical, made of metal, with a smooth surface, and threaded connections at both ends. Coupling 2 connects the motor shaft and the slip ring 3 through an elastic element or a rigid connection, transmitting the rotational motion of the servo motor 1 to the slip ring 3 and the brush 4, ensuring stable power transmission. The connection between coupling 2 and the slip ring 3 passes through the distance fixing plate 5.

[0033] The slip ring 3 is installed at the bottom of the fixed plate 5, directly below the coupling 2, and directly connected to the coupling 2. It is cylindrical and wrapped with insulating material. The slip ring 3 is designed with an air pipe connector 6, which connects to an external 4-bar air source. The air source passes through a small hole inside the slip ring 3 and communicates with the 3mm diameter center hole of the PBT material brush 4, providing pneumatic support for the brush 4. This is used to blow away the screw plugs or assist the rotation of the brush 4.

[0034] The brush 4 is installed below the slip ring 3 and is directly connected to the slip ring 3. The brush handle is fixed to the bottom of the slip ring 3 by threads to achieve quick assembly, and the bristles are densely arranged. The brush 4 removes the screw plug adhesive through rotational friction. The bristles are usually made of wear-resistant materials, and of course, the material and hardness of the bristles are designed and adjusted according to the characteristics of the screw plug adhesive.

[0035] The air pipe connector 6 is installed on the side of the slip ring 3 and is connected to an external air source via a hose. It has threads on its surface for easy connection of the air pipe. The air pipe connector 6 has an internal air passage and achieves an airtight connection through a sealing ring, providing pneumatic support for the brush 4 for blowing away the screw plugs or assisting the rotation of the brush 4.

[0036] When a workpiece reaches this station and is blocked by a retainer, triggering a positioning signal, the positioning clamp above the area and the screw-clogging adhesive removal device fixed to the clamp receive the signal and descend via a slide rail. The brush 4 on the screw-clogging adhesive removal device descends and presses into the workpiece by 2mm. The PLC sends a command to the servo motor 1, which drives the brush 4 to rotate and begin scraping the white adhesive off the workpiece. Simultaneously, air is blown through the center hole of the brush 4 to clean the workpiece surface, effectively removing the screw-clogging adhesive. After completion, the clamp rises, the retainer is removed, the workpiece is released, and the work cycle ends.

[0037] This invention uses a servo motor 1 to drive a coupling 2 and a slip ring 3, which in turn rotates a brush 4. The rotational friction of the brush 4 removes the adhesive plugging. The slip ring 3 and the air pipe connector 6 provide rotational force and pneumatic support, ensuring the brush 4 operates normally during rotation. The distance fixing plate 5 ensures the structural stability of the entire device and facilitates precise operation. This device effectively solves the shortcomings of traditional adhesive removal methods, improves adhesive removal efficiency and safety, and avoids damage to the surface being cleaned.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
