[0015] A capacitor is a passive electronic component used to store electric charge; its fundamental characteristic is the ability to store electric field energy. In related technologies, capacitors are typically coated with highly insulating materials (such as tape) to prevent short circuits caused by contact between the capacitor's leads or casing and other components, while also achieving high-voltage isolation. However, currently, capacitor coating still relies on manual labor. The specific operations include manually cutting coating material to a specific length and then using the material to coat the folded capacitor. This coating process heavily depends on manual experience, resulting in poor coating consistency, low production efficiency, and high labor costs. To address this issue, this application provides a coating device 100 (… Figure 1 or Figure 2 (as shown) and the coating method ( Figure 11 (As shown).

[0016] Please see Figure 1 and Figure 2 The overmolding apparatus 100 provided in this application includes a feeding mechanism 10, a receiving mechanism 20, a glue-receiving mechanism 30, and an overmolding mechanism 40. The feeding mechanism 10 is configured to feed the part 110 to be overmolded. The receiving mechanism 20 is configured to receive and fix the part 110 to be overmolded from the feeding mechanism 10. The glue-receiving mechanism 30 includes a feeding assembly 31 and a receiving assembly 33. The feeding assembly 31 is configured to load the overmolding material 130, and the receiving assembly 33 is configured to remove the overmolding material 130 from the feeding assembly 31. The overmolding mechanism 40 includes a cutting component 41 and an overmolding component 43. The cutting component 41 is configured to cut the connection between the overmolding material 130 taken out by the material taking component 33 and the overmolding material 130 on the feeding component 31, so that the material taking component 33 obtains a preset length of overmolding material 130 to be used. The overmolding component 43 is configured to adhere the overmolding material 130 to be used to the outer peripheral wall of the part to be overmolded 110. The receiving mechanism 20 is further configured to drive the part to be overmolded 110 to rotate relative to the overmolding mechanism 40 when the overmolding component 43 has adhered the overmolding material 130 to the outer peripheral wall of the part to be overmolded 110, so that the overmolding material 130 covers the outer peripheral wall of the part to be overmolded 110.

[0017] The coating device 100 is an automated coating process for the part 110 to be coated. It can complete feeding, positioning, glue removal, and coating processes through multi-mechanism collaboration. The coating device 100 can cover the surface of the part 110 with insulating or protective coating material 130 to achieve electrical isolation or mechanical protection. The part 110 to be coated refers to electronic components or other industrial parts that require coating, such as capacitors and batteries. The coating material 130 refers to a flexible strip or sheet material used to wrap the part 110, which needs to possess insulating and adhesive properties.

[0018] In some embodiments, the component to be coated 110 includes a capacitor, and the coating material 130 includes an adhesive tape. The adhesive tape is made of an insulating material, such as polyester (PET) tape, polyimide (PI) tape, etc. Specifically, please refer to... Figure 4 When the component 110 to be coated includes a capacitor, the component 110 includes a body 1101 and leads 1103. The body 1101 is the core part of the capacitor, including electrodes (positive and negative terminals) and dielectric material, etc. The body 1101 can be a cylinder or a cuboid, etc. The leads 1103 are conductive metal terminals connected to the body 1101. There are two leads 1103, which are located on the same side of the body 1101, or the two leads 1103 are located on opposite sides of the body 1101. In some embodiments of this application, the two leads 1103 are located on the same side of the body 1101, the two leads 1103 are spaced apart and do not contact each other, and both are bent relative to the body 1101. The coating material 130 can cover the outer peripheral wall of the body 1101 to prevent the capacitor leads 1103 or the outer shell (i.e., the shell part of the body 1101) from contacting other components and causing a short circuit, and it is also high voltage resistant and provides isolation.

[0019] The feeding mechanism 10 is the structure responsible for feeding materials in the overmolding device 100. Specifically, the feeding mechanism 10 can orderly feed the parts 110 to be overmolded into the processing area. For example, after picking up materials one by one, the feeding mechanism 10 can transfer the parts 110 to be overmolded to a fixed position on the receiving mechanism 20 according to the required direction, facilitating the normal operation of subsequent processes. The feeding mechanism 10 enables the overmolding device 100 to have an automatic feeding function, which is beneficial for mechanized operation, reduces manual intervention, and improves production efficiency.

[0020] The receiving mechanism 20 is a structure in the overmolding device 100 used to receive and fix the part 110 to be overmolded. It can provide a stable reference for subsequent overmolding processes, achieve precise fixing of the part 110 to be overmolded, and facilitate consistent overmolding. For example, when the feeding mechanism 10 feeds the part 110 to be overmolded to the receiving mechanism 20, the receiving mechanism 20 can receive the part 110 to be overmolded and clamp and fix it after receiving it.

[0021] The adhesive dispensing mechanism 30 is a structure in the adhesive dispensing device 100 used to dispense the adhesive material 130. The feeding assembly 31 is a component in the adhesive dispensing mechanism 30 used to store the adhesive material 130. Exemplarily, the adhesive material 130 can be continuously wound into a roll by manual or mechanical means (such as a winding machine), and the wound roll is loaded onto the feeding assembly 31. The dispensing assembly 33 is a structure in the adhesive dispensing mechanism 30 used to dispense the adhesive material 130 from the feeding assembly 31. Exemplarily, the dispensing assembly 33 can pull out the adhesive material 130 from the feeding assembly 31 by clamping. The length of the adhesive material 130 dispensed by the dispensing assembly 33 each time can be the same, thus ensuring adhesive consistency. It should be noted that, in some embodiments, the dispensing assembly 33 can control the length of the final usable adhesive material 130 by controlling the length of the adhesive material 130 dispensed from the feeding assembly 31.

[0022] The cutting component 41 is a structure in the overmolding mechanism 40 used to cut the overmolding material 130. Specifically, when the picking component 33 takes the overmolding material 130 from the feeding component 31, the cutting component 41 can sever the connection between the overmolding material 130 taken out by the picking component 33 and the overmolding material 130 on the feeding component 31, so that the picking component 33 obtains an overmolding material 130 of a preset length to be used. The preset length can vary depending on the part 110 to be overmolded, thus improving the applicability of the overmolding device 100. That is, the overmolding device 100 can pick up overmolding material 130 of different lengths depending on the part 110 to be overmolded, so as to meet the overmolding requirements (overmolding length and number of overmolding turns, etc.) of different parts 110 to be overmolded. Furthermore, compared to manual overmolding, the cutting component 41 and the material picking component 33 work together to ensure that the material picking component 33 picks up the overmolding material 130 to be used each time is of a preset length. This can solve the problem of excessive overlap of the overmolding material 130 or gaps and omissions during overmolding to a certain extent, thereby effectively improving the consistency of overmolding.

[0023] The overmolding assembly 43 is a component in the overmolding mechanism 40 that adheres the cut overmolding material 130 to the surface of the part to be overmolded 110. For example, the overmolding assembly 43 can press the overmolding material 130 firmly onto the surface of the part to be overmolded 110 using adjustable pressure, improving the flatness of the adhesion between the overmolding material 130 and the part to be overmolded 110, which helps eliminate air bubbles and improves the overmolding quality. Furthermore, compared to manual overmolding, the pressure applied by the overmolding assembly 43 is uniform, thereby preventing uneven stress on the overmolding material 130 that could lead to wrinkles or localized delamination, thus further improving the overmolding quality.

[0024] Specifically, in some embodiments of this application, the part to be coated 110 is cylindrical. When the coating assembly 43 adheres the coating material 130 to the outer peripheral wall of the part to be coated 110, the receiving mechanism 20 can drive the part to be coated 110 to rotate relative to the coating mechanism 40, so that the coating material 130 covers the outer peripheral wall of the part to be coated 110, thereby completing the coating. That is, when the coating material 130 is adhered to the outer peripheral wall of the part to be coated 110, the receiving mechanism 20 drives the part to be coated 110 to rotate to achieve the coating. It should be noted that during the process of the receiving mechanism 20 driving the part to be coated 110 to rotate relative to the coating mechanism 40, the coating assembly 43 always keeps the coating material 130 adhered to the outer peripheral wall of the part to be coated 110. Thus, compared to manual overmolding, the overmolding component 43 ensures that the overmolding material 130 will not experience wrinkles or localized delamination due to uneven stretching caused by the cylindrical curvature of the part to be overmolded 110 during the overmolding process, thereby improving the overmolding quality.

[0025] In the overcoating apparatus 100 of this embodiment, the feeding mechanism 10 is configured to feed the part 110 to be overcoated, the receiving mechanism 20 is configured to receive and fix the part 110 to be overcoated from the feeding mechanism 10, the picking component 33 is configured to pick up the overcoating material 130 from the feeding component 31, the cutting component 41 is configured to cut the connection between the overcoating material 130 picked up by the picking component 33 and the overcoating material 130 on the feeding component 31, so that the picking component 33 obtains an overcoating material 130 of a preset length, and the overcoating component 43 is configured to adhere the overcoating material 130 to be used to the outer peripheral wall of the part 110 to be overcoated. Furthermore, when the coating assembly 43 attaches the coating material 130 to be used to the outer peripheral wall of the part to be coated 110, the receiving mechanism 20 can drive the part to be coated 110 to rotate relative to the coating mechanism 40 so that the coating material 130 covers the outer peripheral wall of the part to be coated 110. In this way, the coating device 100 can realize the mechanized operation of coating the part to be coated 110, that is, the coating device 100 can realize automatic feeding, picking up and coating, replacing manual operation, reducing manual participation, saving labor costs, and helping to reduce costs and increase efficiency. Moreover, the mechanization of coating operation also helps to improve coating consistency and effectively improve production efficiency and yield.

[0026] In addition, manual tape coating also has problems such as uneven force application (when manually operating the tape, it is difficult to control the tension precisely; if it is too tight, the tape material 130 will be overstretched and deformed or even cracked; if it is too loose, the tape material 130 will not adhere tightly and the edges will lift up), positioning deviation (the positioning is prone to deviation by sight and touch, and the tape material 130 cannot perfectly center and wrap the part to be coated 110, resulting in insufficient insulation distance, requiring rework, affecting the coating quality and production efficiency), air bubbles or wrinkles (when manually operating the tape material 130, tiny air bubbles are easily wrapped in or wrinkles are formed, causing local insulation to be weak), and uneven finishing (the flatness and overlap of the finishing of the tape material 130 are difficult to unify). In the coating device 100 of this application embodiment, the coating component 43 and the receiving mechanism 20 cooperate to achieve rotational coating in the bonding state, which effectively solves the problem of uneven force causing the coating material 130 to be too loose or too tight, which is beneficial to improving the coating quality. At the same time, it can also solve the problem of local insulation weakness caused by air bubbles or wrinkles. Through the cooperation of the glue taking mechanism 30 and the cutting component 41, the glue taking mechanism 30 can obtain the coating material 130 to be used of a preset length, thereby solving the problem of uneven end, and the flatness and overlap of the end of the coating material 130 can be uniform. By realizing the coating operation through mechanical automation, the problem of positioning offset can be solved, preventing the coating material 130 from failing to effectively center and wrap the part to be coated 110, resulting in insufficient insulation distance, thereby improving the coating quality, while improving production efficiency and production yield.

[0027] Please see Figure 1 and Figure 2 In some embodiments, the coating device 100 further includes a machine base 50, on which the feeding mechanism 10, the receiving mechanism 20, the glue-taking mechanism 30, and the coating mechanism 40 are all mounted. The machine base 50 provides support and protection for the feeding mechanism 10, the receiving mechanism 20, the glue-taking mechanism 30, and the coating mechanism 40, ensuring the stable operation of each mechanism.

[0028] Please combine Figure 3 In some embodiments, the overmolding apparatus 100 further includes a pressing mechanism 60, which is mounted on the machine base 50 and configured to press the top of the part 110 to be overmolded onto the receiving mechanism 20. Specifically, the pressing mechanism 60 is configured to press the top of the part 110 to be overmolded onto the receiving mechanism 20 when the receiving mechanism 20 drives the part 110 to be overmolded to rotate. Thus, the pressing mechanism 60 prevents the part 110 to be overmolded from falling off the receiving mechanism 20 during rotation, thereby ensuring the stable operation of the overmolding process.

[0029] In some embodiments, the coating apparatus 100 further includes a feeding mechanism 70, which is mounted on the machine base 50 and configured to remove the coated part 110 from the receiving mechanism 20. Specifically, the feeding mechanism 70 is configured to remove the coated part 110 from the receiving mechanism 20 after the coating material 130 has covered the outer peripheral wall of the part 110, and to store or transport it to the next process. The feeding mechanism 70 enables the coating apparatus 100 to have an automatic feeding function, further improving the automation of the coating apparatus 100, reducing manual intervention, and improving production efficiency.

[0030] As described above, the two pins 1103 are located on the same side of the body 1101, with no contact between them, and both are bent relative to the body 1101. During the overmolding process, the overmolding material 130 needs to bypass the pins 1103 of the part to be overmolded 110. This may result in the overmolding material 130 contacting the pins 1103, causing a large angular deviation of the pins 1103, which in turn leads to a significant change in the distance between the two pins 1103. It may also cause the overmolding material 130 to deform, affecting the subsequent overmolding quality.

[0031] Please combine Figure 4 In some embodiments of this application, the receiving mechanism 20 is further configured to drive the part to be coated 110 to rotate relative to the coating mechanism 40 to a preset position (e.g., Figure 4 (The position of the part to be coated 110 shown in the figure) In the preset position, along the rotation direction of the part to be coated 110, the pin 1103 of the part to be coated 110 is spaced apart from the coating mechanism 40; the coating mechanism 40 is also configured to: after the receiving mechanism 20 drives the part to be coated 110 to rotate to the preset position, apply the coating material 130 to be used to the outer peripheral wall of the part to be coated 110.

[0032] That is, before the coating mechanism 40 applies the coating material 130 to the outer peripheral wall of the part to be coated 110, the receiving mechanism 20 can drive the part to be coated 110 to rotate at a certain angle so that the coating material 130 avoids the pins 1103 of the part to be coated when it applies to the part to be coated 110. This can reduce the possibility of interference between the coating material 130 and the pins 1103 during the subsequent coating process, thereby not only preventing the pins 1103 from deviating in angle, but also preventing the coating material 130 from deforming and improving the coating quality.

[0033] Please see Figure 2 and Figure 5In some embodiments, the feeding mechanism 10 includes a support member 11, a clamping assembly 13, and a drive assembly 15. The clamping assembly 13 is configured to clamp the part 110 to be coated. The drive assembly 15 is mounted on the support member 11 and connected to the clamping assembly 13, and is configured to drive the clamping assembly 13 to rotate. The drive assembly 15 is also configured to drive the clamping assembly 13 and the part 110 to be coated to rotate together relative to the support member 11 when the clamping assembly 13 is clamping the part 110 to be coated, so as to feed the part 110 to be coated.

[0034] The support member 11 is a structure in the feeding mechanism 10 used to load components such as the clamping assembly 13 and the drive assembly 15. The support member 11 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. In some embodiments, the support member 11 can be made of aluminum alloy, which increases its structural strength, reduces the possibility of damage, and improves the stability and reliability of the feeding mechanism 10. In other embodiments, the support member 11 can be made of plastic, which makes it lighter and facilitates the lightweight design of the feeding mechanism 10.

[0035] The clamping assembly 13 is a structure in the feeding mechanism 10 used to clamp and transfer the part 110 to be coated. The driving assembly 15 is a structure in the feeding mechanism 10 used to drive the clamping assembly 13 to rotate. Specifically, when the clamping assembly 13 clamps the part 110 to be coated, the driving assembly 15 can drive the clamping assembly 13 and the part 110 to be coated held by the clamping assembly 13 to rotate together relative to the support member 11, so as to feed the part 110 to be coated, that is, to transfer the part 110 to be coated to the receiving mechanism 20 in a specified direction. For example, the driving assembly 15 can drive the clamping assembly 13 from... Figure 5 The right side of the relative support member 11 rotates to Figure 5 The left side of the middle (e.g.) Figure 2 (the position of the clamping component 13), thereby transferring the part to be coated 110 to the receiving mechanism 20.

[0036] In some embodiments, the clamping assembly 13 includes a clamping cylinder 131 and a clamping member 133. The clamping cylinder 131 is configured to drive the clamping member 133 to clamp the part 110 to be coated. The driving assembly 15 includes a driving member 151 and a transmission member 153. The driving member 151 is mounted on the support member 11. The transmission member 153 is connected between the output end of the driving member 151 and the clamping cylinder 131. The transmission member 153 is configured to transmit the driving force of the driving member 151 to the clamping cylinder 131 and drive the clamping cylinder 131 and the clamping member 133 to rotate together relative to the support member 11.

[0037] The clamping cylinder 131 is the power source of the clamping assembly 13. It drives mechanical movement via compressed air to control the opening and closing of the clamping member 133, thereby clamping the part 110 to be coated. The clamping cylinder 131 can be a pneumatic finger cylinder, etc. The clamping member 133 is the structure in the clamping assembly 13 that directly contacts and can grip the part 110 to be coated. The clamping member 133 can be a V-groove gripper or a flat gripper, etc. The clamping member 133 can grip the part 110 to be coated under the driving action of the clamping cylinder 131, and the clamping cylinder 131 can control the opening and closing of the clamping member 133, so that the clamping member 133 can grip parts 110 of different sizes, improving the applicability of the feeding mechanism 10. It is understood that in other embodiments, the clamping assembly 13 may also include other forms. For example, the clamping assembly 13 includes a power source and a clamping member 133. The clamping member 133 includes a fixed plate and a movable plate. The fixed plate and the movable plate can jointly clamp the part 110 to be coated. The power source drives the movable plate to move relative to the fixed plate to control the opening and closing of the clamping member 133, so that the clamping member 133 can clamp different parts 110 to be coated.

[0038] The drive element 151 is a structure in the drive assembly 15 used to provide driving force. The drive element 151 includes, but is not limited to, an electric motor, a cylinder, an internal combustion engine, and a pneumatic motor. The transmission element 153 is a structure in the drive assembly 15 used to transmit the driving force of the drive element 151 to the clamping assembly 13, thereby driving the clamping assembly 13 to rotate relative to the support member 11. For example, when the drive element 151 includes an electric motor, the output shaft of the motor can be connected to the transmission element 153 to drive the clamping assembly 13 to rotate relative to the support member 11 via the transmission element 153.

[0039] Please see Figure 2 and Figure 6 In some embodiments, the receiving mechanism 20 includes a mounting base 21, a rotating assembly 23, and a receiving assembly 25 connected to the rotating assembly 23. The rotating assembly 23 is mounted on the mounting base 21 and configured to drive the receiving assembly 25 to rotate. The receiving assembly 25 includes a receiving member 251 and a power member 253. The power member 253 is connected to the receiving member 251 and configured to drive the receiving member 251 to switch between a first state and a second state. In the first state, the receiving member 251 can receive the part 110 to be coated from the feeding mechanism 10 and does not restrict the degree of freedom of the part 110 to be coated in the direction perpendicular to the extension of the part 110. In the second state, the receiving member 251 can fix the part 110 to be coated and restrict the degree of freedom of the part 110 to be coated in the direction perpendicular to the extension of the part 110.

[0040] The mounting base 21 is a structure in the receiving mechanism 20 used to mount components such as the rotating component 23 and the receiving component 25. The mounting base 21 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. In some embodiments, the mounting base 21 can be made of aluminum alloy, which increases its structural strength, reduces the possibility of damage, and improves the stability and reliability of the receiving mechanism 20. In other embodiments, the mounting base 21 can be made of plastic, which makes it lighter and facilitates the portability of the receiving mechanism 20.

[0041] The rotating component 23 is a structure in the receiving mechanism 20 used to drive the receiving component 25 to rotate. In some embodiments of this application, the rotating component 23 is further configured to: drive the receiving component 25 to rotate before the coating component 43 applies the coating material 130 to be used to the outer peripheral wall of the part to be coated 110, so that the part to be coated 110 on the receiving component 25 rotates to a preset position relative to the coating mechanism 40; and, when the coating component 43 applies the coating material 130 to be used to the outer peripheral wall of the part to be coated 110, drive the receiving component 25 and the part to be coated 110 on the receiving component 25 to rotate together relative to the coating mechanism 40, so that the coating material 130 covers the outer peripheral wall of the part to be coated 110.

[0042] The receiving component 25 is a structure in the receiving mechanism 20 used to receive and fix the part 110 to be coated. The power component 253 is a structure in the receiving component 25 used to output driving force. The power component 253 includes, but is not limited to, an electric motor, a cylinder, an internal combustion engine, and a pneumatic motor. The receiving member 251 is a structure in the receiving component 25 used to realize the receiving and fixing functions. In some embodiments of this application, the power component 253 is further configured to: drive the receiving member 251 from a second state to a first state during the feeding process of the feeding mechanism 10 to feed the part 110 to be coated, so that the receiving member 251 receives the part 110 to be coated from the feeding mechanism 10; and after the receiving member 251 receives the part 110 to be coated from the feeding mechanism 10, drive the receiving member 251 from the first state to the second state, so that the receiving member 251 fixes the part 110 to be coated.

[0043] The first state can be: the state in which the receiving member 251 can receive the part 110 to be coated from the feeding mechanism 10, and the receiving member 251 does not restrict the degree of freedom of the loaded part 110 in the direction perpendicular to the extension of the part 110; the second state can be: the state in which the receiving member 251 can fix the part 110 to be coated, and the receiving member 251 can restrict the degree of freedom of the loaded part 110 in the direction perpendicular to the extension of the part 110. That is, in the first state, the feeding mechanism 10 can feed the part 110 to be coated onto the receiving member 251; or, the unloading assembly 70 ( Figure 1 As shown, the receiving mechanism 20 can remove the coated part 110 from the receiving part 251. In the second state, the receiving mechanism 20 fixes the coated part 110 in place, ensuring that the coated part 110 will not shift during the subsequent coating process, thereby improving the coating quality and ensuring coating consistency.

[0044] Please combine Figure 7 In some embodiments, the receiving member 251 includes two receiving portions 2511, each of which is provided with a receiving groove 2513. The two receiving grooves 2513 are correspondingly arranged and configured to jointly accommodate the part 110 to be coated from the feeding mechanism 10. The power member 253 is configured to drive the two receiving portions 2511 to move relative to each other, so that the receiving member 251 switches between a first state and a second state. In the first state, there is a first gap between the two receiving portions 2511. In the second state, there is a second gap between the two receiving portions 2511. The size of the first gap is larger than the size of the second gap, and the size of the first gap is smaller than the size of the part 110 to be coated in the direction perpendicular to the extension of the part 110.

[0045] Specifically, in some embodiments, when the power member 253 drives the two receiving parts 2511 to move relatively far apart, the receiving member 251 can switch from a second state to a first state; when the power member 253 drives the two receiving parts 2511 to move relatively close, the receiving member 251 can switch from the first state to the second state. That is, the power member 253 can control the gap size between the two receiving parts 2511, thereby enabling the receiving member 251 to receive and fix different parts 110 to be coated, thus improving the applicability of the receiving mechanism 20. For example, the power member 253 can be a pneumatic finger cylinder, which is connected to the two bearing parts and used to control the opening and clamping of the two bearing parts, thereby enabling the receiving member 251 to switch between the first state and the second state.

[0046] The size of the first gap is smaller than the size of the part to be coated 110 in the direction perpendicular to the extension of the part to be coated 110. This ensures that the part to be coated 110 is contained in the two receiving grooves 2513 and will not fall into the gap between the two receiving parts 2511, thereby ensuring the normal progress of the subsequent coating process.

[0047] In some embodiments, the receiving mechanism 20 further includes an elastic element 27 disposed in the receiving groove 2513. When the part to be coated 110 is placed in the receiving groove 2513, the elastic element 27 is located between the part to be coated 110 and the inner wall of the receiving groove 2513. It should be noted that in some embodiments, the material of the elastic element 27 includes, but is not limited to, rubber, silicone, and urethane.

[0048] The elastic element 27 serves two main purposes: firstly, it provides cushioning protection for the part to be coated 110; when the part to be coated 110 is fed into the bearing groove, the elastic element 27 buffers external forces to prevent rigid collisions between the part to be coated 110 and the receiving element 251, thus preventing damage. Secondly, it increases the friction between the part to be coated 110 and the inner wall of the bearing groove, preventing the part to be coated 110 from shifting or even detaching due to excessive rotation speed during the rotation of the receiving mechanism 20, thereby improving the stability and reliability of the coating device 100. Furthermore, the elastic element 27 also enables precise positioning of the part to be coated 110, improving coating consistency.

[0049] In some embodiments, the rotating assembly 23 includes a drive motor 231, a coupling 233, and a pneumatic slip ring 235. The drive motor 231 is mounted on the mounting base 21. The coupling 233 is connected between the output end of the drive motor 231 and the pneumatic slip ring 235. The receiving assembly 25 is connected to the pneumatic slip ring 235. The coupling 233 is configured to transmit the driving force of the drive motor 231 to the pneumatic slip ring 235 so that the rotating end of the pneumatic slip ring 235 rotates and drives the receiving assembly 25 to rotate.

[0050] Specifically, in some embodiments, when the drive motor 231 is operating stably, the driving force of the drive motor 231 can be transmitted to the coupling 233, and the rotating end of the pneumatic slip ring 235 is driven to rotate through the coupling 233. In this case, the receiving component 25 can rotate together with the rotating end of the pneumatic slip ring 235. The pneumatic slip ring 235 can achieve 360° continuous rotation to drive the receiving component 25 and the part 110 to be coated on the receiving component 25 to rotate, and a stable and uninterrupted gas transmission can be achieved during rotation. For example, when the power component 253 is a cylinder (such as a pneumatic finger cylinder), the pneumatic slip ring 235 can transmit gas to the power component 253 to ensure the stable operation of the power component 253. That is, the stationary end of the pneumatic slip ring 235 is fixedly installed and connected to an external air source pipeline, ensuring a stable air supply to the power component 253 when the rotating end of the pneumatic slip ring 235 drives the receiving component 25 to rotate.

[0051] Please see Figure 2 and Figure 4 and combined Figure 8 In some embodiments, the feeding assembly 31 includes a discharge member 311 and a feeding member 313. The discharge member 311 is provided with a discharge port 3110. One end of the overmolding material 130 is wound around the feeding member 313, and the other end passes through the discharge port 3110. The discharge port 3110 is configured to switch between an open state and a closed state. The picking assembly 33 includes a clamping member 331 and a moving member 333. The clamping member 331 is configured to clamp the overmolding material 130 at the discharge port 3110. The moving member 333 is connected to the clamping member 331 and is configured to drive the clamping member 331 to move away from or towards the discharge port 3110. The movable member 333 is also configured to: when the discharge port 3110 is open and the clamping member 331 clamps the feeding assembly 31, drive the clamping member 331 to move away from the discharge port 3110 so as to pull out the coating material 130 on the feeding assembly 31 through the discharge port 3110.

[0052] Specifically, in some embodiments, the feeding assembly 31 further includes a loading seat 315, which is a structure in the feeding assembly 31 used to load components such as the discharge component 311 and the feeding component 313. The loading seat 315 may be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. In some embodiments, the loading seat 315 may be made of aluminum alloy, which can increase the structural strength of the loading seat 315, reduce the possibility of damage to the loading seat 315, and improve the stability and reliability of the feeding assembly 31. In other embodiments, the loading seat 315 may be made of plastic, which can make the loading seat 315 lighter and facilitate the lightweighting of the feeding assembly 31.

[0053] The discharge component 311 is a structure in the feeding assembly 31 capable of outputting the overmolding material 130 (such as tape or film). The discharge port 3110 is an opening structure on the discharge component 311 for outputting the overmolding material 130 to the outside of the feeding assembly 31. The shape and size of the discharge port 3110 can match the cross-sectional shape and size of the overmolding material 130. For example, the discharge port 3110 can be a slit-type opening. In some embodiments of this application, the open state can be the state in which the discharge port 3110 is located when the overmolding material 130 can freely pass through the discharge port 3110 for subsequent material removal; the closed state can be the state in which the discharge port 3110 is located when the overmolding material 130 cannot freely pass through the discharge port 3110. It can be understood that in the closed state, the discharge port 3110 can restrict the overmolding material 130 from retracting or extending after material removal is completed.

[0054] The feeder 313 is a structural component in the feed assembly 31 used to store and release the overcoating material 130. The feeder 313 can be a reel or a hopper, etc., and can ensure that the overcoating material 130 is continuously supplied to the discharge port 3110. In some embodiments of this application, the feeder 313 can be passively unwound, that is, the overcoating material 130 is released by the force (tension) of the take-up assembly 33.

[0055] The clamping member 331 is a structural component in the material handling assembly 33 that directly contacts and clamps the overmolding material 130. It can accurately clamp the overmolding material 130 at the discharge port 3110 and ensure that it does not fall off or shift during movement. In some embodiments of this application, the clamping member 331 includes a clamping plate 3311 and a clamping plate cylinder 3313. The clamping plate cylinder 3313 controls the clamping and opening of the clamping plate 3311 by opening and closing, thereby realizing the clamping of the overmolding material 130.

[0056] The moving component 333 is a structural component that drives the clamping component 331 to perform linear or rotary motion, enabling the clamping component 331 to move in a direction away from or towards the discharge port 3110. Furthermore, the moving component 333 can control the length of the overmolding material 130 picked up by the material handling assembly 33 by controlling the travel distance of the clamping component 331. The moving component 333 includes, but is not limited to, servo motors, cylinders, and linear motors. For example, the output end of the moving component 333 is connected to the clamping component 331 to drive the clamping component 331 to move linearly in a direction away from or towards the discharge port 3110. During the overmolding process, the moving part 333 can drive the clamping part 331 to move from the origin towards the outlet 3110, so that the clamping part 331 can clamp the overmolding material 130 at the outlet 3110. When the clamping part 331 clamps the overmolding material 130 at the outlet 3110, the moving part 333 can drive the clamping part 331 to move away from the outlet 3110 and pull out the overmolding material 130 of the required length. Furthermore, after the overmolding is completed, that is, after the overmolding material 130 covers the outer peripheral wall of the part to be overmolded 110, the moving part 333 can drive the clamping part 331 back to the origin and wait for the next material removal.

[0057] Please see Figure 2 , Figure 4 and Figure 8 In some embodiments, the discharge component 311 includes a rotating wheel 3111 and a fixed block 3113, which are arranged side by side. The discharge port 3110 includes a gap between the fixed block 3113 and the rotating wheel 3111. The feeding assembly 31 also includes a power element 317 connected to the fixed block 3113. The power element 317 is configured to drive the fixed block 3113 to move toward or away from the rotating wheel 3111, thereby switching the discharge port 3110 between an open state and a closed state. The power element 317 is also configured to: drive the fixing block 3113 to move away from the rotating wheel 3111 when the receiving mechanism 20 receives and fixes the part 110 to be coated from the feeding mechanism 10, so as to switch the discharge port 3110 from the closed state to the open state; the moving element 333 is also configured to: drive the clamping element 331 to move towards the discharge port 3110 when the discharge port 3110 switches from the closed state to the open state, so as to clamp the coating material 130 at the discharge port 3110.

[0058] Specifically, in some embodiments, the coating material 130 includes an adhesive tape. The adhesive side of the tape can be connected to the rotating wheel 3111, and the non-adhesive side of the tape corresponds to the fixing block 3113. Thus, a linear contact can be formed between the adhesive side of the tape and the rotating wheel 3111. Compared to a surface contact between the adhesive side of the tape and the rotating wheel 3111, the contact area between the adhesive side of the tape and the rotating wheel 3111 is smaller, thereby preventing the tape from sticking to the rotating wheel 3111 and preventing the coating material 130 from being picked up by the material-picking component 33, thus ensuring the normal operation of the coating process. It should be noted that in some embodiments, the rotating wheel 3111 may include a rotating column with rollers or balls mounted on it.

[0059] In some embodiments, the fixing block 3113 is made of an elastic material, such as the entire fixing block 3113 being made of an elastic material, or the area on the fixing block 3113 that can contact the overmolding material 130 being made of an elastic material. The elastic material can be urethane, silicone, or rubber, etc. This allows a soft contact to be formed between the fixing block 3113 and the overmolding material 130 when the discharge port 3110 is in a closed state, preventing the discharge component 311 from damaging the overmolding material 130, reducing the possibility of wrinkles in the overmolding material 130, and thus improving the overmolding quality.

[0060] In other embodiments, a fixing pad 3115 is provided on the side of the fixing block 3113 opposite to the rotating wheel 3111. The fixing pad 3115 is made of an elastic material, such as urethane, silicone, or rubber. Thus, when the discharge port 3110 is closed, a soft contact can be formed between the fixing block 3113 and the overmolding material 130, preventing damage to the overmolding material 130 by the discharge component 311, reducing the possibility of wrinkles in the overmolding material 130, and thereby improving the overmolding quality.

[0061] Please combine Figure 4 In some embodiments, the feeding assembly 31 further includes a limiting block 319, which is disposed between the feeding member 313 and the discharging member 311. The overmolding material 130 passes through the limiting block 319, which is configured to adjust the tension of the overmolding material 130.

[0062] Specifically, the limiting block 319 is a structural component in the feeding assembly 31 used to adjust the tension of the overmolding material 130 and guide its movement. The limiting block 319 can be made of metal (such as steel, aluminum alloy, etc.) or polymer materials (such as polyurethane, rubber, etc.). The limiting block 319 can adjust the tension of the overmolding material 130 to control its tightness, preventing it from becoming too loose or overstretched. This prevents the overmolding material 130 from breaking due to overstretching and keeps it taut, facilitating precise control of the length of the overmolding material 130 taken by the feeding assembly 33. Furthermore, the feeding assembly 31 can also limit the vertical width of the overmolding material 130 through the limiting block 319, and the limiting block 319 can be quickly adjusted via bolts, that is, the width of the overmolding material 130 matched to the limiting block 319 can be adjusted by bolts.

[0063] Please see Figure 2 , Figure 9 and Figure 10 In some embodiments, the cutting assembly 41 includes a first force-applying member 411 and a cutting member 413 connected to the first force-applying member 411. The first force-applying member 411 is configured to drive the cutting member 413 to move relative to the adhesive-taking mechanism 30 to switch between a first position and a second position. In the first position, the cutting member 413 is spaced apart from the adhesive-coating material 130. In the second position, the cutting member 413 is capable of severing the connection between the adhesive-coating material 130 taken out by the material-taking assembly 33 and the adhesive-coating material 130 on the material-feeding assembly 31. The adhesive-coating assembly 43 includes a second force-applying member 431 and a rolling member 433 connected to the second force-applying member 431. The second force-applying member 431 is configured to drive the rolling member 433 to move relative to the adhesive-taking mechanism 30 to switch between a third position and a fourth position. In the third position, the rolling member 433 is spaced apart from the adhesive-coating material 130. In the fourth position, the rolling member 433 is capable of adhering the adhesive-coating material 130 to the outer peripheral wall of the part 110 to be coated.

[0064] Specifically, in some embodiments, the overmolding mechanism 40 further includes a support base 45, which is a structure in the overmolding mechanism 40 used to load components such as the cutting component 41 and the overmolding component 43. The support base 45 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. In some embodiments, the support base 45 can be made of aluminum alloy, which can increase the structural strength of the support base 45, reduce the possibility of damage to the support base 45, and improve the stability and reliability of the overmolding mechanism 40. In other embodiments, the support base 45 can be made of plastic, which can make the support base 45 lighter, which is beneficial to the portability of the overmolding mechanism 40.

[0065] The first force-applying component 411 is the power drive module in the cutting assembly 41, responsible for providing linear or rotary motion, driving the cutting component 413 to switch between a first position (such as a standby position) and a second position (cutting position) to complete the cutting action of the overmolding material 130, so that the material picking assembly 33 can obtain the overmolding material 130 of a preset length. The first force-applying component 411 includes, but is not limited to, motors and cylinders.

[0066] The cutting component 413 is a structural member in the cutting assembly 41 used to cut the overmolding material 130. Exemplarily, the cutting component 413 can be a sheet-like structure, thereby ensuring that the edges of the cut overmolding material 130 are neat, which helps solve the problem of uneven finishing of the overmolding material 130. In some embodiments of this application, the cutting component 413 includes a mounting part and a cutting part. The mounting part is connected to the output end of the first force-applying member 411, and the cutting part is connected to the mounting part and used to cut the overmolding material 130. The cross-sectional shape of the mounting part cut by a plane perpendicular to the cutting direction can be triangular, and the cross-sectional shape of the cutting part cut by a plane perpendicular to the cutting direction can be square. This ensures that the edges of the cut overmolding material 130 are neat, which helps solve the problem of uneven finishing of the overmolding material 130. It should be noted that the mounting part and the cutting part are an integral structure; or, the mounting part and the cutting part are separate structures, and are connected together by a detachable or non-detachable connection method.

[0067] Specifically, the first force-applying component 411 can drive the cutting component 413 to move linearly, so that the cutting component 413 switches between a first position and a second position. In the first position, the cutting component 413 is spaced apart from the coating material 130 to avoid accidental contact; in the second position, the cutting component 413 can quickly sever the connection between the coating material 130 taken out by the picking component 33 and the coating material 130 on the feeding component 31, so that the picking component 33 obtains a preset length of coating material 130 to be used.

[0068] The second force-applying component 431 is the power drive module in the overmolding assembly 43, responsible for providing linear or rotary motion to drive the rolling component 433 to switch between a third position (such as a standby position) and a fourth position (adhesion position) to adhere the pre-set length of overmolding material 130 obtained by the material picking component 33 to the outer peripheral wall of the part to be overmolded 110. The second force-applying component 431 includes, but is not limited to, motors and cylinders.

[0069] The roller 433 can evenly adhere the overmolding material 130 to the outer surface of the part to be overmolded 110 through rolling or pressing actions, ensuring no air bubbles or wrinkles. When the part to be overmolded 110 is cylindrical, the central axis of the roller 433 is parallel to the central axis of the part to be overmolded 110, ensuring precise adhesion between the roller 433 and the part to be overmolded 110. For example, the roller 433 can be a pressing roller, such as a cylindrical silicone or metal roller.

[0070] Specifically, the second force-applying member 431 can drive the rolling member 433 to move linearly, so that the rolling member 433 switches between a third position and a fourth position. In the fourth position, the rolling member 433 can adhere the overmolding material 130 to the outer peripheral wall of the part to be overmolded 110. Furthermore, when the receiving mechanism 20 drives the part to be overmolded 110 to rotate, the rolling member 433 can roll along the outer peripheral wall of the part to be overmolded 110, so that the overmolding material 130 is kept in close contact with the outer peripheral wall of the part to be overmolded 110. After the overmolding is completed, the second force-applying member 431 drives the rolling member 433 to reset, that is, drives the rolling member 433 to switch to the third position.

[0071] Please see Figures 1 to 10In some embodiments of this application, the coating process of the coating device 100 for the coating part 110 may include: first, the clamping assembly 13 clamps the part 110 to be coated, and while the clamping assembly 13 is clamping the part 110, the driving assembly 15 drives the clamping assembly 13 and the part 110 to be coated to rotate together relative to the support member 11, so as to feed the part 110 to be coated; then, the receiving mechanism 20 receives and fixes the part 110 to be coated from the feeding mechanism 10. Specifically, during the feeding process of the feeding mechanism 10, the power member 253 drives the receiving member 251 from the first When the second state switches to the first state, the receiving mechanism 20 can receive the part to be coated 110. After the receiving part 251 receives the part to be coated 110 from the feeding mechanism 10, the power component 253 drives the receiving part 251 to switch from the first state to the second state. At this time, the receiving mechanism 20 can fix the part to be coated 110. Then, the material taking component 33 takes out the coating material 130 from the feeding component 31. That is, when the discharge port 3110 is in the open state and the clamping component 331 clamps the feeding component 31, the moving component 333 drives the clamping component 331 to move away from the discharge port 3110.

Finally, when the coating assembly 43 applies the coating material 130 to be used to the outer peripheral wall of the part to be coated 110, the receiving assembly 25 drives the part to be coated 110 to rotate relative to the coating mechanism 40 so that the coating material 130 covers the outer peripheral wall of the part to be coated 110, thereby completing the coating operation of the part to be coated 110.
