Description

Technical Field

[0001] This invention belongs to the field of coating equipment technology, specifically, it relates to an automatic chemical coating device for screw-in parts. Background Technology

[0002] During the installation of mechanical equipment on high-speed trains, a fastener is applied between the bolt threads to prevent bolts from loosening during operation. The principle of the fastener is that when a screw is screwed into an object or a bolt into a workpiece (nut), the friction generated under preload achieves a tightening effect. The fastener fills and cures the gaps between the threads, preventing the screws (bolts) from loosening and also providing a seal.

[0003] Patent application number CN114289243A discloses a bolt lubricant application device, which includes a crank-slider mechanism configured to drive an application device to reciprocate on a bolt platform to apply lubricant to the bolt. The bolt platform is configured to support the bolt, allowing it to rotate while the lubricant is applied. The bolt is placed horizontally on the bolt platform, and the crank-slider mechanism drives a brush to reciprocate on the platform. The bolt platform supports the bolt and allows it to rotate in place, enabling automatic application of lubricant. However, during the application process, the brush is moving while the bolt is rotating, which prevents the lubricant from filling all threads, resulting in uneven application. When the bolt and nut are tightened, the bolt fails to achieve its anti-loosening purpose.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic chemical coating device for screw fasteners. By generating relative movement between the clamping module and the coating module along the axial direction of the screw fastener during the coating process, the fastener is vertically applied to the threads of the screw fastener, thereby improving the uniformity of the coating.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] An automatic chemical coating device for screw-in connectors, comprising:

[0008] The system comprises a base, a clamping module, and a coating module, wherein the clamping module is used to clamp the screw-in component; the clamping module and / or the coating module are movably mounted on the base.

[0009] The clamping module and the coating module are movably arranged relative to each other along the axial direction of the screw connector, and are used to coat the outer surface of the screw connector.

[0010] Furthermore, the coating module is movably mounted on the base;

[0011] The coating module reciprocates along the axial direction of the screw connection.

[0012] Alternatively, the coating module may reciprocate along the axial direction of the screw connector.

[0013] Furthermore, the base is provided with a mounting groove, which is located on one side of the axial extension direction of the screw connector. The end of the coating module away from the coating end is movably disposed in the mounting groove along the axial direction of the screw connector, so as to provide space for the coating end of the coating module to move along the axial direction of the screw connector.

[0014] Furthermore, the coating module includes a drive mechanism mounted on the base, which drives the coating end of the coating module to swing back and forth.

[0015] Preferably, the driving mechanism includes a cam, which is driven to rotate by a driving component mounted on the base, and the brushing end of the brushing module contacts the cam.

[0016] Furthermore, the base has a recessed storage groove inside, which is used to store screw-in parts;

[0017] The coating module is horizontally disposed in the side wall at the top of the storage tank;

[0018] The clamping module includes a clamping member, the bottom of which is provided with a receiving portion. The clamping member is slidably disposed in the storage slot to extract the screw connector when it moves upward.

[0019] Preferably, the clamping member is recessed downwards, and the clamping member consists of two opposing clamping rods to vertically clamp the screw connector. The distance between the two clamping rods forms the receiving portion to limit the screw joint of the screw connector.

[0020] Furthermore, the edge of the storage slot is provided with a mounting base, the bottom of which is flush with the top of the coating module, and the clamping member is movably inserted into the mounting base.

[0021] Preferably, the two clamping members are arranged to move relative to each other to adjust the distance between the two clamping members;

[0022] The mounting base has a transverse vibration groove inside. The clamping module also includes a sliding member with a certain extension length disposed in the vibration groove. The clamping member passes through the sliding member, and the side wall of the sliding member is connected to the inner wall of the vibration groove through an adjustable elastic member.

[0023] Furthermore, there are two coating modules, which are located on both sides of the clamping module.

[0024] Preferably, the coating module is movably inserted into the side wall of the base, and the two coating modules can move relative to each other or away from each other.

[0025] Furthermore, it also includes a vibration module, which is mounted on the base and contacts the clamping member or the sliding member. When the clamping member picks up the screw connector, it transmits vibration to the clamping member so that the screw connector enters a preset position in the receiving part.

[0026] Furthermore, it also includes a storage module, mounted on the base, for storing fastener;

[0027] The storage module is connected to the coating module.

[0028] Furthermore, it also includes

[0029] A support member, connected to the base, forms a closed funnel-shaped limiting area to restrict the movement of the screw-in component;

[0030] Preferably, it also includes

[0031] A support frame is located at the bottom of the storage slot.

[0032] The actuating element is slidably mounted on the support frame and extends partially into the limiting area;

[0033] The actuating element moves back and forth along the height direction of the storage slot.

[0034] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0035] 1. The automatic chemical coating device for threaded connectors of the present invention includes a base, a coating module, and a clamping module, which have the functions of storage, clamping, and automatic coating. When it is necessary to coat the threaded section of the threaded connector, the clamping module first clamps the threaded connector to fix it, and then the coating module moves back and forth along the axial direction of the threaded connector to coat the fastener into the thread of the threaded connector. The automatic coating by the coating module improves the uniformity of coating and also improves work efficiency.

[0036] 2. The automatic chemical coating device for screw connectors of the present invention includes a clamping module comprising a sliding shaft and a clamping member. The sliding shaft drives the clamping member to slide and extend within the storage tank. After the clamping member clamps the screw connector in the storage tank, the sliding of the sliding shaft drives the sliding of the clamping rod to automatically extract the screw connector from the storage tank.

[0037] 3. The automatic chemical coating device for screw connectors of the present invention is equipped with a vibration module. The vibration module vibrates the clamping component to ensure that the clamping component can be smoothly inserted into the screw connector, thereby avoiding the clamping component being unable to be inserted into the screw connector.

[0038] At the same time, the present invention has a simple structure, a concise method, and significant effects, making it suitable for widespread use.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] like Figures 1 to 8As shown, this invention provides an automatic chemical coating device for threaded connections, used to apply chemical agents to the external threads of threaded connections. Specifically, the chemical agent can be a lubricant, lubricating oil, or fastener. The lubricant and lubricating oil are used to reduce friction and improve sealing; the fastener is used to improve the anti-loosening and sealing effects of the threaded connection.

[0055] The automatic chemical coating device for threaded fasteners in this invention can coat threaded fasteners ranging in size from M5 to M8. In this embodiment, the threaded fastener can be a screw or bolt. The coating area can be the entire threaded section of the threaded fastener or limited to that section. In this embodiment, the application of fastener to the threaded section of the threaded fastener is described as an example.

[0056] The automatic chemical coating device for threaded fasteners of the present invention includes a base 1, a clamping module 4, and a coating module 2. The clamping module 4 is mounted on the base 1 and is used to clamp the threaded fastener. The coating module 2 is mounted on the base 1 and is used to coat the threaded section of the threaded fastener. The clamping module 4 and / or the coating module 2 are movably disposed on the base 1, and the clamping module 4 and the coating module 2 are movable relative to each other along the axial direction of the threaded fastener.

[0057] When it is necessary to apply fastener to the threaded section of the bolt, the clamping module 4 first clamps the bolt to fix it. The clamping module 4 and the application module 2 then move relative to each other along the axial direction of the bolt, applying the fastener into the bolt's threads. The application module 2 enables automatic application of fastener to the bolt, and the applied fastener flows along the direction of the threads, improving the uniformity of the application.

[0058] In this embodiment, either the clamping module 4 or the coating module 2 can move. That is, the coating module 2 moves back and forth along the axial direction of the screw connector during the coating process, while the clamping module 4 remains fixed; or the clamping module 4 moves back and forth along the axial direction of the screw connector during the coating process, while the coating module 2 remains fixed. Alternatively, the clamping module 4 and the coating module 2 can move simultaneously.

[0059] Specifically, the base 1 has an open top and an internal storage slot 11 that communicates with the top opening. When screw fasteners need to be stored, they can be placed directly into the storage slot 11 through the opening. With the storage slot 11, the automatic chemical coating device for screw fasteners has the function of storing screw fasteners. In this embodiment, the shape of the base 1 can be chosen arbitrarily; preferably, the base 1 is a cuboid or cube, which provides a large storage capacity while facilitating easy placement and removal.

[0060] In this embodiment, both the clamping module 4 and the coating module 2 are located on the top of the base 1, at the opening of the base 1. When the clamping module 4 takes out the screw connector from the storage slot 11, the coating module 2 can directly apply the fastener to the threaded section of the screw connector.

[0061] In this embodiment, when the clamping module 4 clamps the screw connector, the screw connector is in a vertical position, that is, the screw connector head is at the top and the threaded part of the screw connector is at the bottom. During the coating process, the threaded screw connector rod is exposed, and the entire threaded section of the screw connector is coated by the up and down movement of the coating module 2.

[0062] In this embodiment, two coating modules 2 are provided, both mounted on the base 1 and located at the top of the base 1. The two coating modules 2 are located on opposite sides of the clamping module 4. When coating the threaded component, both coating modules 2 move up and down simultaneously to apply the fastener. By providing two coating modules 2, the coating effect can be further improved, as the two modules 2 can cover all threaded sections of the threaded component, ensuring the uniformity of the coating effect.

[0063] In this embodiment, the coating module 2 is movably mounted on the base 1. The coating end of the coating module 2 reciprocates along the axial direction of the threaded component; or the coating end of the coating module 2 moves reciprocally along the axial direction of the threaded component. By moving or oscillating the coating module 2, the threaded component is coated. During the movement or oscillation, the coating section can cover the entire threaded section, resulting in high coating efficiency.

[0064] Specifically, the coating module 2 includes a coating rod 21 and a brush head 2101. The coating rod 21 is movably mounted on the base 1, and the coating rod 21 and brush head 2101 are detachably connected or fixedly connected. Preferably, the coating rod 21 and brush head 2101 are detachably connected to facilitate quick replacement of the brush head 2101. During coating, a fastener is applied to the brush head 2101, and the brush head 2101 contacts the threaded section of the screw connector, applying the fastener from the brush head 2101 to the threaded section of the screw connector.

[0065] In this embodiment, to ensure the coating effect on the screw connector, the brush rod 21 can slide up and down to achieve the coating effect. Specifically, a mounting groove 2002 is provided in the base 1, and the end of the brushing module 2 away from the brushing end is movably disposed in the mounting groove 2002 along the axial direction of the screw connector, providing space for the brushing end of the brushing module 2 to move along the axial direction of the screw connector. When coating is performed, the brush rod 21 moves back and forth between the bottom wall and the top wall of the mounting groove 2002, thereby achieving the coating effect.

[0066] In this embodiment, the up-and-down sliding of the brush rod 21 can be achieved by a driving mechanism, such as a cylinder, a linear motor, or an electric actuator. Taking a cylinder as an example: the cylinder body is mounted on the base 1, the output end of the cylinder is located in the mounting groove 2002, and the brush rod 21 is connected to the output end of the cylinder. The up-and-down movement of the brush rod 21 is achieved by extending and retracting the cylinder.

[0067] In this embodiment, reciprocating motion is achieved through the cooperation of sensors and a controller. The appropriate stroke of the brush rod 21 is determined based on its displacement requirements. Sensors are installed at the upper and lower limit positions of the mounting slot 2002, respectively. By detecting the position of the brush rod 21 through these sensors, the brush rod 21 can reciprocate between these two limit positions. Specifically, the sensors can be infrared sensors or through-beam sensors.

[0068] In this embodiment, the reciprocating sliding of the brush rod 21 can also be achieved by using a drive motor in conjunction with a slide rail and a slider. In this embodiment, this type of structure will not be described in detail.

[0069] In this embodiment, the brush rod 21 can also apply the coating to the threaded parts by swinging it up and down. The up-and-down swinging motion of the brush rod 21 allows for covering a larger coating area, significantly improving coating efficiency. Through continuous and uniform swinging motion, the fastener can be evenly distributed on the surface of the threaded parts, avoiding problems of localized excessive or insufficient thickness.

[0070] In this embodiment, the coating module 2 further includes a drive mechanism 24. The drive mechanism 24 can form a curved path through its own structure, and the coating rod 21 performs a reciprocating oscillating motion along the curved path. During coating, the drive mechanism 24 is activated, and the drive mechanism 24 uses its own structure to form a specific curved path. The coating rod 21 oscillates according to the specific curved path formed by the drive mechanism 24.

[0071] In this embodiment, the driving mechanism 24 includes a driving component and a swinging component. The driving component is mounted on the base 1, and the swinging component is driven to rotate by the driving component. The rotation of the swinging component causes the brush rod 21 to swing.

[0072] Specifically, the drive unit is mounted on the inner wall of the base 1, and the oscillating component is connected to the output shaft of the drive unit. When the output shaft of the drive unit rotates, it drives the oscillating component to rotate. Since the oscillating component has a curved profile, the brush rod 21, as the driven component, will move along the predetermined trajectory of the oscillating component, thus achieving the oscillating effect.

[0073] In this embodiment, the driving component can be a motor or a combination of a motor and a reduction gear. The oscillating component can be a cam or an eccentric wheel.

[0074] In this embodiment, in order to improve the stability of the brush rod 21 when swinging, a swing bracket 23 is provided in the mounting groove 2002. There are two swing brackets 23, which are located on both sides of the mounting groove 2002 respectively. The two swing brackets 23 are rotatably connected to the side wall of the corresponding mounting groove 2002.

[0075] In this embodiment, to facilitate the installation of the brush rod 21 and ensure synchronous rotation, a connector is provided between the two swing brackets 23. The brush rod 21 is mounted on the connector, and each swing bracket 23 has a groove formed on it. During installation, the connector is inserted between the two swing brackets 23 through the groove on the swing bracket 23, making installation convenient and quick.

[0076] In this embodiment, the connector is a plate-shaped structure, and the swinging member contacts the connector. By rotating the swinging member, the connector swings, thereby realizing the swinging of the brush rod 21. Because the contact area of ​​the connector is larger, the transmission with the swinging member is more stable, and the coating effect is more uniform.

[0077] In this embodiment, the swing bracket 23 is rotatably connected to the inner wall of the mounting groove 2002 via a rotating shaft. A sliding groove is provided on the inner wall of the mounting groove 2002, within which the rotating shaft slides. Through the cooperation of the rotating shaft and the sliding groove, the connecting parts achieve a sliding connection; that is, the sliding design between the brush rod 21 and the base 1 allows adjustment of the distance between the brush heads 2101 on both sides, accommodating brushing of screw-in parts of different diameters and improving the practicality and adaptability of the device.

[0078] In this embodiment, multiple brush rods 21 are provided, each mounted on a connector. The brush rods 21 are spaced apart and arranged along the length of the base 1. Each brush rod 21 corresponds to a brush head 2101. When brushing the screw-in connectors, the clamping module 4 can simultaneously clamp multiple screw-in connectors, allowing for simultaneous brushing of each connector using the brush rods 21 and brush heads 2101. This allows for the simultaneous brushing of multiple screw-in connectors, avoiding the hassle of brushing them one by one and improving brushing efficiency.

[0079] In this embodiment, the brush head 2101 is preferably made of a flexible material, which ensures both adsorption of the fastener and high flexibility, allowing the fastener to be evenly applied to the threads of the screw-in component without damaging the thread surface. In this embodiment, the brush head 2101 can be made of sponge material.

[0080] In this embodiment, the base 1 is also provided with a storage module 3 for storing fastener, and the storage module 3 is connected to the coating module 2. By setting the storage module 3, fastener can be continuously and automatically supplied to the coating module 2. When coating the screw-in parts, the fastener is loaded into the storage module 3, and the fastener is automatically delivered to the brush head 2101 through the storage module 3, ensuring the continuous coating effect of the brush head 2101. There is no need to manually add fastener to the brush head 2101, which improves convenience and flexibility, and can also improve work efficiency.

[0081] Specifically, the storage module 3 is a storage box. To facilitate communication between the storage module 3 and the coating module 2, in this embodiment, the storage module 3 is mounted on the connector, and a channel is formed inside the connector and the coating rod 21. The storage module 3 communicates with the brush head 2101 through the channel. When the brush head 2101 coats the screw-in component, the fastener in the storage module 3 flows to the brush head 2101 through the internal channel, thereby achieving the purpose of continuously providing fastener to the brush head 2101.

[0082] In this embodiment, the channel can be a pipe or a flow channel.

[0083] In this embodiment, to facilitate the installation of the storage module 3, a mounting hole 2001 is provided on the connector. The mounting hole 2001 communicates with the internal channel, and the storage module 3 is embedded in the mounting hole 2001. The following description uses a storage box as an example:

[0084] In this embodiment, the storage box is made of plastic, and the storage box and the mounting hole 2001 are interference-fitted. The opening of the storage box communicates with the internal channel. When applying the coating to the screw-in component, the brush rod 21 swings up and down, and then the storage box is inserted into the mounting hole 2001. Due to the interference fit between the storage box and the mounting hole 2001, the storage box is compressed, and the fastener inside the storage box is squeezed into the channel, and further enters the brush head 2101 through the channel. In this embodiment, the brush head 2101 is made of sponge material, and the brush head 2101 absorbs the fastener in the channel and further applies the coating to the screw-in component.

[0085] In this embodiment, the channel includes a first flow channel 2102 located within the connector and a second flow channel 2103 located within the brush rod 21. The fastener in the storage module 3 enters the brush head 2101 sequentially through the first flow channel 2102 and the second flow channel 2103.

[0086] In this embodiment, each brush rod 21 is provided with a second flow channel 2103. The second flow channel 2103 is arranged along the axial direction of the brush rod 21. One end of the second flow channel 2103 is connected to the first flow channel 2102, and the other end is connected to the brush head 2101.

[0087] In this embodiment, to facilitate simultaneous communication between the first flow channel 2102 and multiple second flow channels 2103, the first flow channel 2102 is divided into two sections. The first section of the first flow channel 2102 is arranged along the axial direction of the brush rod 21, and the second section of the first flow channel 2102 is perpendicular to the first section, that is, the second section of the first flow channel 2102 is perpendicular to the second flow channel 2103. The specific flow path of the fastener is as follows: the fastener flows out from the storage module 3, enters the first section of the first flow channel 2102, then enters the second section of the first flow channel 2102, and is sequentially distributed to each of the second flow channels 2103 through the second section of the first flow channel 2102, and finally reaches the corresponding brush head 2101 through the second flow channel 2103.

[0088] In this embodiment, to facilitate the installation of the clamping module 4, mounting seats are provided at both ends of the base 1. The mounting seats are integrally formed with the base 1. Of course, the clamping module 4 can also be directly installed on the base 1. In this embodiment, the mounting seat is used as an example for explanation.

[0089] In this embodiment, the clamping module 4 includes a clamping member 4202, which is slidably disposed on the base 1. The clamping member 4202 is provided with a receiving part. The clamping member 4202 moves back and forth along the height direction of the storage groove 11 so that the screw connector enters the receiving part, thereby realizing the self-removal of the screw connector.

[0090] In this embodiment, the clamping member 4202 is a clamping rod, and there are two of them, which are used to vertically clamp the screw-in member. There is a gap between the two clamping rods that allows only the threaded section of the screw-in member to pass through in order to form a receiving part.

[0091] In this embodiment, the clamping module 4 further includes two sliding members 43 and two sliding shafts 4201. The clamping member 4202, the sliding member 43, and the sliding shaft 4201 are arranged in a one-to-one correspondence. A vibration groove 41 is provided on the mounting base, which passes through the upper and lower ends of the mounting base. The two sliding members 43 are located in the vibration groove 41 and are arranged in parallel. The two sliding members 43 are slidably connected to the side wall of the corresponding mounting base, that is, the distance between the two sliding members 43 can be adjusted.

[0092] In this embodiment, the sliding shaft 4201 passes through the sliding member 43 along its axial direction and is slidably connected to it. The sliding direction of the clamping member 4202 is perpendicular to the sliding direction of the sliding member 43. Both ends of the clamping member 4202 are connected to the corresponding sliding shaft 4201. Both clamping members 4202 are horizontally arranged and parallel to each other. By using the sliding shaft 4201 for connection, the sliding shaft 4201 and the clamping member 4202 on one side form a U-shape.

[0093] In this embodiment, the clamping module 4 further includes an adjustable elastic element 4301. Each sliding member 43 is connected to the side wall of the mounting base through the adjustable elastic element 4301, and multiple adjustable elastic elements 4301 can be provided on each sliding member 43. To further improve the stability of the sliding member 43 during sliding and to limit the sliding member 43 from sliding out of the vibration groove 41, a limiting hole is also provided in the mounting base. A telescopic support shaft 4302 is provided in the limiting hole. One end of the support shaft 4302 is connected to the bottom wall of the limiting hole, and the other end is connected to the side wall of the sliding member 43. The axis of the support shaft 4302 is perpendicular to the axis of the sliding member 43. When the sliding member 43 slides, the support shaft 4302 telescopically slides together, providing support.

[0094] In this embodiment, to facilitate the insertion of the sliding shaft 4201, a support sliding hole 4303 is formed on the sliding member 43, and a protective sleeve is provided inside the support sliding hole 4303. The protective sleeve and the sliding shaft 4201 are interference-fitted. The protective sleeve is made of nylon material, which is wear-resistant. The interference fit between the sliding shaft 4201 and the protective sleeve prevents the sliding shaft 4201 from sliding freely. At the same time, by pulling the handheld member 42, the sliding shaft 4201 can be pulled to slide synchronously, and the clamping member can be pulled out from the storage slot 11, leaving the screw-in member in a suspended state.

[0095] In this embodiment, to facilitate the sliding of the sliding shaft 4201, a handheld component 42 is connected to the top of the sliding shaft 4201. At the same time, to meet the sliding requirements of the sliding component 43, a support groove 4203 is provided on the handheld component 42, and the ends of each sliding shaft 4201 are engaged in the support groove 4203 and slidably connected to the support sliding shaft 4302.

[0096] In this embodiment, the specific process of clamping the screw connector by the clamping module 4 is as follows:

[0097] The operator presses down on the handheld component 42, causing the sliding shaft 4201 to slide, which in turn causes the clamping component 4202 to slide within the storage slot 11. Due to the presence of the adjustable elastic element 4301, the two clamping components 4202 can elastically extend and retract, increasing the distance between them. During continuous sliding, this ensures that the screw connector falls between the two clamping components 4202. Under the action of the adjustable elastic element 4301, the two clamping components 4202 will move closer together, allowing the screw connector to be clamped tightly, preventing it from loosening during the coating process and affecting the coating effect.

[0098] After the clamping component has removed all the screw-in parts, pull the handle 42 upwards, causing the clamping component 4202 to slide upwards along the storage groove 11 until it moves between the two coating modules 2. Then, slide the connecting component, causing the brush head 2101 to move closer to the clamping component 4202 until the brush head 2101 contacts the external thread on the surface of the screw-in part. Then, insert it into the storage module 3 and start the drive component, causing the drive component to drive the vibrating cam to rotate, thereby realizing the continuous swinging of the coating rod 21 to complete the automatic coating of the screw-in parts. The clamping module 4 achieves the purpose of automatically picking up screw-in parts, improving work efficiency and avoiding the trouble caused by manually picking up screw-in parts one by one.

[0099] In this embodiment, to facilitate easier insertion of the screw connector between the two clamping members 4202 and prevent situations where the screw connector cannot be removed or only a small portion can be removed at once, a vibration module 5 is provided on the mounting base. The vibration module 5 generates vibration and transmits the vibration to the clamping members 4202. During the clamping process of the screw connector, the vibration generated by the vibration module 5 loosens the screw connector, making it easier for the clamping members 4202 to insert into the screw connector, thereby allowing the screw connector to enter the gap between the two clamping members 4202.

[0100] In this embodiment, the vibration module 5 can also transmit vibration to the clamping member 4202 when the clamping member 4202 is gripping the screw connector, so that the screw connector enters a preset position in the receiving part. The preset position is that the axis of the screw connector is in a vertical state.

[0101] In this embodiment, the vibration module 5 can be a vibration motor, a mechanical vibrator, a spring-mass system, or other structures capable of generating vibration. In this embodiment, a vibration motor will be used as an example for specific explanation.

[0102] Specifically, a groove is provided on the side of the mounting base away from the storage slot 11. The vibration motor is engaged in the groove, and the output shaft of the vibration motor extends into the vibration slide 41. The end of the output shaft of the vibration motor is connected to a pressing vibration head 54. In this embodiment, the pressing vibration head 54 is a cam structure. The vibration motor drives the pressing vibration head to rotate, which can press the sliding parts 43 on both sides, so that the clamping part 4202 is in a vibrating state.

[0103] In this embodiment, the vibratory motor can be removed from the groove. When the vibratory motor is not placed in the groove, the distance between the two sliding members 43 is less than the size of the top-pressing vibratory head 54, that is, the distance between the two sliding members 43 is at its minimum, ensuring that the screw connector can be clamped. When the vibratory motor is placed in the groove, the top-pressing vibratory head 54 is inserted between the two sliding members 43, increasing the distance between the two sliding members 43, making it easier to insert the screw connector. After the screw connector is removed, the vibratory motor is taken out of the groove, and the distance between the two sliding members 43 returns to its minimum under the action of the adjustable elastic member 4301.

[0104] In this embodiment, the end of the top-pressure vibrating head is a conical structure, which facilitates insertion between the two sliding members 43.

[0105] In this embodiment, to prevent the vibratory motor from falling out of the groove during operation, the motor needs to be secured. Specifically, this includes a limiting bracket 51, a second elastic element 52, and a rotating head 53. The limiting bracket 51 is L-shaped, with one end connected to the end of the vibratory motor via the second elastic element 52. The rotating head 53 is connected to the other end of the limiting bracket 51 and is rotatably connected to the mounting base. The second elastic element 52 presses the vibratory motor firmly into the groove, achieving a limiting effect and preventing the vibratory motor from detaching from the groove. Simultaneously, the rotation of the rotating head 53 controls the swinging of the limiting bracket 51.

[0106] In this embodiment, the specific working process is as follows: insert the vibration motor into the groove, start the vibration motor, and at the same time press down the hand-held part 42 so that the clamping part 4202 moves vertically in the storage slot 11. By cooperating with the two clamping parts 4202 and vibrating the clamping part 4202, the clamping part can be smoothly inserted into the screw connector, and the screw connector can be picked up by itself.

[0107] After the screw connector is extracted, the vibration motor is removed from the groove, reducing the distance between the two clamping parts 4202 and clamping the screw connector. Then, the connecting part is pushed, bringing the brush heads 2101 on both sides closer together. The storage module 3 is then inserted, and the drive unit is activated, causing the cam to rotate, thus making the brushing rod 21 swing up and down continuously, completing the automatic coating of the screw connector. The clamping module 4 and vibration module 5 achieve automatic screw connector retrieval, avoiding the hassle of manually handling each screw connector individually. The coating module 2 achieves automatic coating of the screw connector, improving work efficiency.

[0108] In this embodiment, in order to further improve the efficiency of automatically picking up screws, a limit module is also provided at the bottom of the storage slot 11 to ensure that the two clamping parts 4202 can be smoothly inserted into the screws.

[0109] Specifically, the limiting module includes a support member 6, a third elastic member 61, and a support frame 63. The support member 6 is inclined and there are two support members 6. The two support members 6 gradually approach each other from the top to the bottom of the storage tank 11, forming a V-shaped limiting area. The screw connector is placed in the limiting area, and the screw connector is more concentrated, making it easier to extract.

[0110] In this embodiment, the support frame 63 is disposed at the bottom of the storage tank 11, and one end of the support member 6 away from the support frame 63 is hinged to the base 1, while the other end of the support member 6 is slidably disposed on the support frame 63. The third elastic member 61 is disposed at the middle position of the support member 6, and the other end of the third elastic member 61 is connected to the side wall of the base 1.

[0111] In this embodiment, a motor is mounted on the base 1, and the output shaft of the motor is connected to a first rotating shaft 6201. The first rotating shaft 6201 extends into the storage slot 11 and is located below the support member 6. A first cam 62 is mounted on the first rotating shaft 6201. The first cam 62 is rotated by the motor, thereby achieving the swinging effect of the support member 6.

[0112] In this embodiment, the support member 6 can be a vibrating plate, which is a device capable of generating vibration. Specifically, vibrating plates include various types such as electromagnetic vibrating plates, ultrasonic vibrating plates, and micro vibrating plates. By utilizing the vibration generated by the vibrating plate, and cooperating with the third elastic member 61, the vibrating plate swings, driving the screwed parts within the limiting area to move, thus reducing the difficulty of extraction.

[0113] Furthermore, the support frame 63 includes two vertical plates and one horizontal plate. The two vertical plates are connected to the bottom of the storage tank 11, and the horizontal plate is connected to the two vertical plates, forming a V-shaped structure. There is a gap between the horizontal plate and the bottom of the storage tank 11. A motor is mounted on the base 1, and the output shaft of the motor is connected to a second rotating shaft 6304. The second rotating shaft 6304 extends into the storage tank 11 and is located below the horizontal plate. A second cam 6303 is provided on the second rotating shaft 6304. An actuating element 6301 is slidably mounted on the support frame 63. Part of the actuating element 6301 extends into the limiting area, and a pressing head 6302 is provided at the end of the actuating element 6301 near the bottom of the storage tank 11. When the motor drives the second cam 6303 to rotate, the second cam 6303 actuates the pressing head 6302. Utilizing the structure of the second cam 6303, the actuating element 6301 slides up and down, generating a stirring effect on the screw-in parts within the limiting area, allowing the clamping element to be smoothly inserted into the screw-in parts.

[0114] In this embodiment, a spring can be provided between the pressing head 6302 and the support frame 63. Under the action of the spring, the actuating member 6301 can automatically reset, thereby realizing the reciprocating movement of the actuating member 6301 and achieving continuous operation. Under the synchronous action of the support member 6 and the actuating member 6301, it is easy to insert the clamping member into the screw connection in the storage slot 11, reducing the difficulty of extraction.

[0115] In this embodiment, multiple toggle members 6301 can be provided, and multiple toggle members 6301 can improve the toggle effect. In this embodiment, some motors are not shown and described.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
