[0002] In the technological background of the increasing miniaturization of electronic devices such as vehicle-mounted sensors, the traditional "three-proof (moisture-proof, salt spray-proof, mildew-proof) glue" can no longer meet the needs of protecting electronic devices from water vapor erosion, so nano-coating technology came into being. However, the nano-coating process requires precise masking of non-coated areas to prevent unnecessary coating coverage, which has led to the application of special masking fixtures to ensure the accuracy and efficiency of the coating operation.

[0049] As mentioned in the background art, existing device shielding devices and methods are difficult to meet the production requirements of miniaturization, high efficiency and high quality of automotive electronics.

[0050] To solve the above technical problems, an embodiment of the present invention provides a clamp assembly for clamping at least one device, wherein each of the devices has a non-coated section and a section to be coated along an extension direction, the clamp assembly comprising: a first clamp and a second clamp, the first clamp and the second clamp having an open mold state and a closed mold state, in the open mold state, the first clamp and the second clamp are separated from each other, in the closed mold state, the first clamp and the second clamp are combined with each other to form a accommodating cavity, the accommodating cavity is suitable for accommodating the non-coated section of the at least one device, and the section to be coated of the at least one device is exposed outside the accommodating cavity; a removable positioning portion comprising a first area, the first clamp and the second clamp form the closed mold state in the first area, and the positioning portion is removed after the first clamp and the second clamp form the closed mold state.

[0051] By adopting the technical solution of the present application, the opening and closing design of the first clamping plate and the second clamping plate can quickly and accurately clamp the non-coated section of the device, ensuring that the section to be coated is completely exposed outside the accommodating cavity, thereby improving the efficiency and accuracy of the coating operation. Furthermore, the setting of the positioning part makes the positioning and combination of the first clamping plate and the second clamping plate simpler, faster and more accurate, simplifies the operation process and reduces the difficulty of operation. Furthermore, a pair of first clamping plates and second clamping plates can clamp one or more devices at the same time, effectively improving the efficiency of coating.

[0052] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0053] Figure 1 is a schematic diagram of a clamp assembly 10 according to an embodiment of the present invention, Figure 2 yes Figure 1 Exploded view of the structure shown.

[0054] refer to Figure 1 , a clamp assembly 10, used to clamp at least one device 20, wherein each of the devices 20 has a non-coated section 201 and a section to be coated 202 along the extension direction, the clamp assembly 10 includes: a first clamp plate 1 and a second clamp plate 2, the first clamp plate 1 and the second clamp plate 2 have an open mold state and a closed mold state, in the open mold state, the first clamp plate 1 and the second clamp plate 2 are separated from each other, in the closed mold state, the first clamp plate 1 and the second clamp plate 2 are combined with each other to form a accommodating cavity 3 (shown in a dotted line structure), the accommodating cavity 3 is suitable for accommodating the non-coated section 201 of the at least one device 20, and the section to be coated 202 of the at least one device 20 is exposed outside the accommodating cavity 3; a removable positioning portion 4, including a first area 401, the first clamp plate 1 and the second clamp plate 2 form the closed mold state in the first area 401, and the positioning portion 4 is removed after the first clamp plate 1 and the second clamp plate 2 form the closed mold state.

[0055] Specifically, the device 20 may be, for example, a sensor element (such as a temperature sensor, a pressure sensor, etc.) or other electronic or electrical elements. Before leaving the factory, the device 20 usually needs to be plated on at least part of its area to enhance its corrosion resistance, water resistance and other protective properties, thereby extending the service life of the device 20.

[0056] In some embodiments, the shape of the device 20 can refer to Figure 1 and Figure 2 However, it should be understood that the device 20 shown in the drawings of the present application is only schematic and should not be regarded as any limitation to the present application.

[0057] Furthermore, the device 20 includes a non-coated section 201 and a section to be coated 202 along its extension direction. During the coating process of the device 20, the section to be coated 202 needs to be in full contact with the coating material, while the non-coated section 201 needs to be shielded by the clamp assembly 10 (especially the first clamp 1 and the second clamp 2) to avoid contact with the coating material.

[0058] Furthermore, the fixture assembly 10 can be applied to scenarios requiring high-precision coating operations, such as the nano-coating process of automotive electronic devices. The fixture assembly 10 clamps and protects the non-coated section 201 of the electronic device 20 from being affected by the coating material during the coating process, while ensuring that the section to be coated 202 is fully exposed for coating processing.

[0059] Furthermore, the clamp assembly 10 includes a first clamp plate 1 and a second clamp plate 2 that can cooperate with each other, and the first clamp plate 1 and the second clamp plate 2 can form a closed mold state to clamp the non-coated section 201 of the device 20, or form an open mold state to release the non-coated section 201 of the device 20.

[0060] In some embodiments, in the mold closing state, the first clamping plate 1 and the second clamping plate 2 cover each other, and the first clamping plate 1 and the second clamping plate 2 can be fixedly connected by fixing members 40 such as screws to improve the clamping stability.

[0061] Furthermore, a receiving cavity 3 is formed between the first clamping plate 1 and the second clamping plate 2 in the mold closing state (refer to Figure 1 ), the non-coated section 201 of the device 20 is located in the accommodating cavity 3, and the walls of the first clamping plate 1 and the second clamping plate 2 forming the accommodating cavity 3 can isolate the coating material during the coating process.

[0062] Furthermore, the positioning portion 4 can assist in positioning the first clamp plate 1, the second clamp plate 2 and the device 20 during the process in which the first clamp plate 1 and the second clamp plate 2 cooperate with each other from a separated open mold state to form a closed mold state and clamp the device 20, thereby achieving precise positioning and rapid assembly of the first clamp plate 1, the second clamp plate 2 and the device 20, which helps to improve the efficiency of the coating operation.

[0063] In some embodiments, the positioning portion 4 may be in a plate shape to provide more area for installing the first clamping plate 1 and the device 20 .

[0064] Furthermore, the positioning portion 4 includes a first area 401. In actual operation, after the first clamping plate 1, the non-coated section 201 of the device 20, and the second clamping plate 2 are moved to the first area 401 in sequence, they cooperate with each other to form a pre-assembled component, that is, the first clamping plate 1 and the second clamping plate 2 form a molded state and clamp the non-coated section 201 of the device 20.

[0065] Further, after the first clamp 1 and the second clamp 2 form a molded state and clamp the non-coated section 201 of the device 20, the positioning portion 4 can be removed and the pre-assembled component including the first clamp 1, the second clamp 2 and the device 20 can be transferred to a specific position to perform the coating operation.

[0066] In some embodiments, the number of the devices 20 can be multiple, that is, the first clamping plate 1 and the second clamping plate 2 can simultaneously clamp multiple devices 20 when they are in a clamped state. In this way, the number of devices 20 to be plated in the same batch can be significantly increased, thereby greatly improving the efficiency of the coating.

[0067] From the above, through the opening and closing design of the first clamping plate 1 and the second clamping plate 2, the non-coating section 201 of the device 20 can be clamped quickly and accurately, and the section to be coated 202 can be completely exposed outside the accommodating cavity 3, thereby improving the efficiency and accuracy of the coating operation. Furthermore, the setting of the positioning portion 4 makes the positioning and combination of the first clamping plate 1 and the second clamping plate 2 simple and quick, simplifies the operation process, and reduces the difficulty of operation. Furthermore, through the cooperation of a pair of first clamping plates 1 and second clamping plates 2, one or more devices 20 can be clamped at the same time, effectively improving the efficiency of coating.

[0068] Combination Figures 1 to 4 The positioning portion 4 includes: a limiting portion 41 , which is disposed in the first area 401 and is used to fix the first clamping plate 1 in the first area 401 .

[0069] Specifically, the limiting portion 41 is used to accurately fix the first clamping plate 1 on the first area 401 of the positioning portion 4. Thus, it can be ensured that the first clamping plate 1 will not move or deviate unnecessarily during the subsequent assembly process, thereby improving the overall assembly boundary of the clamp assembly 10 and the stability and accuracy of the pre-assembled assembly formed by the assembly.

[0070] Furthermore, the position limiting portion 41 is also used to guide the second clamping plate 2 to align with the first clamping plate 1. That is, in addition to fixing the first clamping plate 1, the position limiting portion 41 also plays a role in positioning and guiding. For example, the position limiting portion 41 can guide the first clamping plate 1 to be positioned quickly and accurately, and can also guide the second clamping plate 2 to cover the first clamping plate 1 accurately.

[0071] In some embodiments, the first clamping plate 1 is rectangular, and the limiting portion 41 includes: a plurality of protrusions 411 , and the plurality of protrusions 411 are at least used to fix a plurality of corners of the first clamping plate 1 .

[0072] Specifically, the rectangular first clamping plate 1 has many advantages in manufacturing and design, such as easy processing, high standardization, and the ability to provide a stable support surface. In the pre-assembled component, the rectangular first clamping plate 1 can cooperate with the second clamping plate 2 (whose shape matches that of the first clamping plate 1) to form a parallel and symmetrical clamping structure, thereby ensuring the stability and accuracy of the device 20 during the coating process.

[0073] Furthermore, the plurality of protrusions 411 are used to fix at least a plurality of corners of the first clamping plate 1. For example, when fixing the rectangular first clamping plate 1, the number of protrusions 411 may be, for example, four (corresponding to the four corners of the rectangle), or more to provide a more stable fixing effect. Thus, the plurality of protrusions 411 ensure that the first clamping plate 1 is accurately and stably positioned on the first region 401 of the positioning portion 4, preventing accidental movement or offset in subsequent operations.

[0074] In some embodiments, the plurality of protrusions 411 may be formed with matching structures adapted to the edge of the first clamping plate 1, such as grooves for receiving the corners of the first clamping plate 1. Thus, the contact area between the plurality of protrusions 411 and the first clamping plate 1 can be further increased, thereby increasing the stability of the positioning portion 4 in fixing the first clamping plate 1.

[0075] In some embodiments, the positioning portion 4 further includes: a second region 402 located in the same plane as the first region 401 , and the section 202 to be coated of the at least one device 20 is located in the second region 402 . The plane is parallel to the first clamping plate 1 .

[0076] Furthermore, when the device 20 is placed on the fixture, the section to be coated 202 will be directly placed in the second area 402. After the positioning portion 4 is subsequently removed, the section to be coated 202 can be exposed outside the accommodating cavity 3 formed by the first clamp 1 and the second clamp 2, so as to facilitate the coating operation on the section to be coated 202.

[0077] Further, refer to Figure 5 , at least one first mounting portion 11 is provided on one side of the first clamping plate 1 facing the second region 402, for fixing the at least one device 20. The first mounting portion 11 enables the device 20 to be firmly mounted on the first clamping plate 1. Thus, the first mounting portion 11 can ensure that the device 20 is accurately placed at a specific position of the first clamping plate 1 before coating, and can also prevent the device 20 from moving or falling off due to vibration, airflow or other external factors during the coating process.

[0078] In some embodiments, when the device 20 is placed on the first clamping plate 1 , it can be directly connected to the first clamping plate 1 through the first mounting portion 11 , and its section 202 to be coated can accurately correspond to the second area 402 .

[0079] In some embodiments, in combination Figures 1 to 6 The first clamping plate 1 and / or the second clamping plate 2 include: a recessed portion 31 for forming at least a portion of the accommodating cavity 3; the first mounting portion 11 includes a through groove 111 extending along a first direction D1, and the through groove 111 is connected to the recessed portion 31. In the mold closing state, the through groove 111 forms a through hole connected to the accommodating cavity 3, and the section to be coated 202 of the at least one device 20 extends out of the accommodating cavity 3 from the through hole. The first direction D1 is parallel to the first area 401 and points to the direction of the second area 402.

[0080] In a typical application scenario, during the process of the first clamping plate 1 and the second clamping plate 2 forming a clamped state and clamping the device 20, the operator can first place the device 20 (non-coated section 201) on the first clamping plate 1 and fix it by the first mounting portion 11. In this process, at least a portion of the device 20 enters the through groove 111. Then move the second clamping plate 2 close to and finally cover the first clamping plate 1 to form the accommodating cavity 3 and close the opening of the through groove 111. At this time, the wall of the first clamping plate 1 that forms the through groove 111 and the wall of the second clamping plate 2 facing the first clamping plate 1 jointly form a through hole connecting the accommodating cavity 3. In addition, the section 202 to be coated of the device 20 extends out of the accommodating cavity 3 from the through hole. Further, when the device 20 is mounted on the first clamping plate 1 and the positioning portion 4, the extension direction of the device 20 is parallel to the first direction D1 (such as Fig. 9 ).

[0081] In some embodiments, the outer peripheral surface of the device 20 and the inner wall of the through hole are tightly fitted to ensure the sealing of the accommodating cavity 3, thereby preventing the coating material from entering the accommodating cavity 3 from the gap between the device 20 and the inner wall of the through hole during the coating process, thereby affecting the yield of the device 20.

[0082] In some embodiments, the recessed portion 31 may be formed in the first clamping plate 1 .

[0083] In some embodiments, the recessed portion 31 may be formed in the second clamping plate 2 .

[0084] In some embodiments, both the first clamping plate 1 and the second clamping plate 2 may be provided with a recessed portion 31. When the first clamping plate 1 and the second clamping plate 2 are in a mold-clamping state, the recessed portions 31 on both sides jointly form a receiving cavity 3.

[0085] Continue to refer Figures 1 to 4In some embodiments, the positioning portion 4 further includes: at least one second mounting portion 42, which is disposed at the junction of the first region 401 and the second region 402, and the at least one second mounting portion 42 is used to position the at least one device 20, and the at least one second mounting portion 42 corresponds to the at least one first mounting portion 11. Thus, the second mounting portion 42 can cooperate with the corresponding first mounting portion 11, so that the positioning of the corresponding device 20 is more accurate, ensuring that the device 20 is always kept in an accurate position during the process of the first clamping plate 1 and the second clamping plate 2 forming a clamped state and clamping the device 20.

[0086] In some embodiments, the second mounting portion 42 may include a mounting groove, the extending direction of the mounting groove may be consistent with the through groove 111, and the mounting groove is aligned with or connected to the corresponding through groove 111. Thus, the second mounting portion 42 can be combined with the first mounting portion 11 to provide a double fixing effect for the device 20, significantly enhance the stability of the device 20 setting position, and prevent the device 20 from being offset or falling when the second clamping plate 2 covers the first clamping plate 1.

[0087] In some embodiments, the second mounting portion 42 and the first mounting portion 11 can be adjusted and configured according to the specific shape and coating requirements of the device 20 so that the fixture assembly 10 has strong adaptability and flexibility to be suitable for devices 20 of various shapes and sizes.

[0088] In some embodiments, the positioning portion 4 may further include: a third mounting portion 43, which is disposed in the second region 402, and the third mounting portion 43 is used to fix the at least one device 20. Thus, the third mounting portion 43 can cooperate with the first mounting portion 11 (located on the first clamping plate 1) and the second mounting portion 42 (located at the junction of the first region 401 and the second region 402) to form a multi-level fixing system to ensure the stability and accuracy of the device 20 when the first clamping plate 1 and the second clamping plate 2 are in the mold-clamping state.

[0089] Furthermore, the third mounting portion 43 includes at least one pair of clamping arms 431 disposed opposite to each other, and a gap is formed between the pair of clamping arms 431 for at least a portion of the device 20 to enter. When the device 20 is placed on the first clamping plate 1, the section 202 to be coated of the device 20 can enter the gap formed by the corresponding pair of clamping arms 431.

[0090] In some embodiments, the width of the gap (i.e., the distance between the pair of clamp arms 431) may be slightly larger than the width of the section of the device 20 accommodated in the gap. Thus, when the positioning portion 4 is subsequently removed, the device 20 can easily leave the gap, facilitating operation.

[0091] In some embodiments, reference Figures 1 to 4 , Figures 7 to 9 , the fixture assembly 10 further includes: a locking portion 5, which is detachably connected to the second region 402, and the locking portion 5 is used to lock the at least one device 20 to the positioning portion 4. Thus, the locking portion 5 is detachably connected to the second region 402, and can firmly lock the to-be-coated section 202 of the device 20 on the positioning portion 4, so as to prevent the device from moving or falling off due to vibration, external force or other factors during the process of the second clamping plate 2 covering the first clamping plate 1. In addition, when removing the positioning portion 4, the locking portion 5 is removed to unlock the device 20, so as to facilitate the operation of removing the positioning portion 4.

[0092] In some embodiments, the locking portion 5 can also ensure that the device 20 is stably fixed in the first mounting portion 11, so as to facilitate the subsequent installation of the first sealing structure 6 and / or the second sealing structure 7 (see Figure 5 and Figure 6 ) operation. Wherein, the first sealing structure 6 and / or the second sealing structure 7 can be, for example, a colloid material such as hot melt adhesive.

[0093] Furthermore, the locking portion 5 includes at least one groove portion 51 arranged at intervals along the extension direction, wherein each of the groove portions 51 is used to cooperate with the positioning portion 4 to jointly enclose a receiving hole for receiving the to-be-coated section 202 of the device 20. Thus, during the process of installing the locking portion 5 to the positioning portion 4, the to-be-coated section 202 of the device 20 enters the groove portion 51, and as the locking portion 5 and the positioning portion 4 are assembled, the surface of the positioning portion 4 forming the second region 402 can close the opening of the groove portion 51 to form a receiving hole, and at this time, at least a portion of the to-be-coated section 202 is received in the receiving hole.

[0094] In some embodiments, the number of the locking parts 5 is two, and the two locking parts 5 are arranged at intervals along the direction (for example, the first direction D1) from the first area 401 to the second area 402. Thus, the two locking parts 5 can respectively lock the two ends of the section to be coated 202, further enhancing the stability of the device 20 fixed on the positioning part 4, and preventing the device 20 from unexpectedly shifting or falling off during the process of the first clamping plate 1 and the second clamping plate 2 forming a clamped state.

[0095] In some embodiments, the locking portion 5 and the positioning portion 4 are detachably connected via a magnetic connector 52 , and the magnetic connector 52 includes at least one pair of magnetic elements respectively disposed on the locking portion 5 and the positioning portion 4 .

[0096] Specifically, refer to Figure 4 and Figure 8The magnetic connector 52 is composed of at least one pair of magnetic components, which are respectively arranged on the locking portion 5 and the positioning portion 4. When the locking portion 5 is close to the positioning portion 4, the magnetic components will automatically be adsorbed and firmly connected together due to the interaction force between the magnetic components. This connection method not only simplifies the installation and disassembly process, but also improves the stability and reliability of the connection.

[0097] Furthermore, a plurality of mounting holes 53 may be provided on the surfaces of the locking portion 5 and the positioning portion 4 that are away from each other. The mounting holes 53 may be blind holes, for example, and the plurality of mounting holes 53 provided on the locking portion 5 correspond to the plurality of mounting holes 53 provided on the positioning portion 4. Furthermore, the pair of magnetic attracting members are respectively provided in the mounting holes 53 corresponding to each other, and attract each other to finally realize the magnetic attraction connection between the locking portion 5 and the positioning portion 4.

[0098] In some embodiments, along the extension direction of the locking portion 5, both ends of the locking portion 5 can also be connected to the positioning portion 4 by screws and other fixing parts to further increase the firmness of the connection between the locking portion 5 and the positioning portion 4, so that the section 202 to be coated can be stably accommodated in the accommodating hole to avoid shaking or falling during the process of the first clamping plate 1 and the second clamping plate 2 forming a mold closing state.

[0099] Further, if Fig. 9 As shown, the connection between the locking portion 5 and the positioning portion 4 can lock the to-be-coated section 202 of the component 20 on the positioning portion 4 .

[0100] In some embodiments, continue to refer to Figure 5 and Figure 6 A first sealing structure 6 is disposed around the first clamping plate 1 , or a second sealing structure 7 is disposed around the second clamping plate 2 .

[0101] In some embodiments, a first sealing structure 6 is disposed around the first clamping plate 1, and a second sealing structure 7 is disposed around the second clamping plate 2. Thus, when the first clamping plate 1 and the second clamping plate 2 form a mold-clamping state, at least one of the first sealing structure 6 and the second sealing structure 7 can close any gap between the first clamping plate 1, the second clamping plate 2 and the device 20 to ensure the sealing of the accommodating cavity 3. Thus, it can be prevented that the coating material enters the accommodating cavity 3 from the above-mentioned gap during the coating operation to affect the yield rate of the device 20.

[0102] In some embodiments, the surface of the first clamping plate 1 with the recessed portion 31 may be provided with an annular groove around the recessed portion 31, and the annular groove is used to fill the sealing material to form the first sealing structure 6. Correspondingly, the surface of the second clamping plate 2 used to fit with the first clamping plate 1 may also be provided with an annular groove to fill the sealing material to form the second sealing structure 7.

[0103] Furthermore, in the mold closing state, the annular groove provided on the first clamping plate 1 and the annular groove provided on the second clamping plate 2 can be butted against each other to form a complete channel containing the sealing material. Alternatively, in the mold closing state, the first clamping plate 1 closes the annular groove located on the second clamping plate 2, and the second clamping plate 2 closes the annular groove located on the first clamping plate 1. Thus, the first sealing structure 6 and the second sealing structure 7 can play a double sealing role on the accommodating cavity 3, further improving the sealing performance of the accommodating cavity 3.

[0104] In some embodiments, the sealing material may be, for example, a colloid material such as hot melt adhesive.

[0105] As described above, by adopting the technical solution of the present application, through the opening and closing design of the first clamp 1 and the second clamp 2, the non-coated section 201 of the device 20 can be clamped quickly and accurately, and the section to be coated 202 can be ensured to be completely exposed outside the accommodating cavity 3, thereby improving the efficiency and accuracy of the coating operation.

[0106] Furthermore, the provision of the positioning portion 4 makes the positioning and combination of the first clamping plate 1 and the second clamping plate 2 simple and quick, simplifies the operation process, and reduces the difficulty of operation.

[0107] Furthermore, through the cooperation of a pair of first clamping plates 1 and second clamping plates 2, one or more devices 20 can be clamped at the same time, which effectively improves the efficiency of coating.

[0108] Furthermore, through the multiple guarantees of the limiting portion 41, the first mounting portion 11, the second mounting portion 42, the third mounting portion 43 and the locking portion 5, the device 20 is stably clamped during the entire coating operation, avoiding coating quality problems caused by movement or falling of the device 20. At the same time, the design of the magnetic connector 52 also improves the convenience, reliability and durability of the clamp assembly 10.

[0109] refer to Fig.10 and Fig.11 The embodiment of the present invention further provides a coating assembly 100, comprising: at least one of the above Figures 1 to 9 The fixture assembly 10 of the illustrated embodiment; the frame structure 30 is used to carry the at least one fixture assembly 10, and the frame structure 30 has a receiving space 301, and the section 202 to be coated of the at least one device 20 respectively clamped by the at least one fixture assembly 10 is accommodated in the receiving space 301. Therefore, by transferring the first clamping plate 1 and the second clamping plate 2 in the clamping state in the fixture assembly 10 clamping at least one device 20 to the frame structure 30, multiple devices 20 can be coated at the same time, further improving the efficiency of coating.

[0110] Furthermore, the positioning portion 4 in the clamp assembly 10 is removed before the clamp assembly 10 is transferred to the frame structure 30 .

[0111] Furthermore, at least one side wall 302 of the frame structure 30 that forms the accommodating space 301 is provided with a notch 303 to allow the coating material to enter the accommodating space 301 .

[0112] In some embodiments, the frame structure 30 may further include: a plurality of connection beams 305 , and along the extension direction, the plurality of connection beams 305 are supported between the side walls 302 .

[0113] Further, refer to Fig.11 The frame structure includes a pair of side walls 302 arranged opposite to each other, and each side wall includes a first side 3021, a second side 3022, a third side 3023 and a fourth side 3024 adjacent to each other. The two ends of the plurality of connecting beams 305 are respectively connected to the second side 3022, the third side 3023 and the fourth side 3024 of each side wall 302 of the pair of side walls 302. The plurality of connecting beams 305 connected to the third side 3023 are used to form the bottom wall of the frame structure 30. Thus, during the coating operation, the coating material can quickly enter the accommodating space 301 and fully contact with the to-be-coated sections 202 of the plurality of devices 20 accommodated therein to coat the to-be-coated sections 202, thereby improving the efficiency of the coating operation.

[0114] Further, the frame structure 30 may include: at least one pair of slots 304, which are respectively opened on opposite walls of the frame structure 30 forming the accommodating space 301, and at least a portion of the first clamping plate 1 and the second clamping plate 2 in the mold closing state are inserted into the slots 304 to be connected with the frame structure 30. Thus, the first clamping plate 1 and the second clamping plate 2 in the mold closing state can be fixed on the frame structure 30 by simple plugging, which is simple to operate and is conducive to improving the efficiency of the coating operation.

[0115] For the specific structure and function of the clamp assembly 10, please refer to the previous Figures 1 to 8 The relevant description of the illustrated embodiment is not repeated here.

The first clamping plate, the second clamping plate and the device clamped between the first clamping plate and the second clamping plate in the mold closing state form a pre-assembled component to facilitate the subsequent coating operation. In this way, the efficiency of coating can be greatly improved.
