Description

Technical Field

[0001] This invention relates to the field of processing and manufacturing technology, and in particular to a bonding method for bonding a drive module to a laminated glass cloth sheet. Background Technology

[0002] The drive module is a hybrid integrated circuit used to control parameters such as motor speed and rotation direction. It mainly consists of a housing, a top cover, an integrated circuit board, and pins. The top cover and the housing are connected by laser spot welding. The drive module is filled with nitrogen gas at one atmosphere of pressure to form a sealed package.

[0003] However, due to the large size of the high-power drive module and the thinness of the top cover, and the lack of a supporting structure for the top cover in the middle of the module, the rigidity of the top cover is low. Under some high-pressure impact conditions, the top cover may deform. When the deformation exceeds the critical value, the top cover will damage the internal integrated circuit board. In fact, the deformed top cover may cause a short circuit inside the module, leading to the burnout and failure of the drive module.

[0004] To address the aforementioned issues, a bonding method for bonding the drive module to the laminated glass cloth sheet is needed to improve its resistance to high-pressure impact. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a bonding method for bonding a drive module to a laminated glass cloth board, in order to solve the problem that the top cover of the existing drive module is easily deformed under high pressure impact, resulting in damage to the internal circuit.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] A method for bonding a laminated glass cloth sheet to a drive module, using an adhesive tooling to bond the laminated glass cloth sheet to the drive module, includes the following steps:

[0008] Step S1: Apply a certain thickness of sealant to the laminated glass cloth board and place it on the top cover of the drive module;

[0009] Step S2: Install the drive module onto the base plate of the bonding fixture;

[0010] Step S3: Press down the upper cover plate of the bonding fixture to press the laminated glass cloth board onto the upper surface of the drive module; and adjust the thickness of the sealant between the laminated glass cloth board and the drive module by controlling the amount of pressure applied by the upper cover plate.

[0011] Step S4: After the laminated glass cloth board is pasted on, allow the drive module to cure. Once the sealant has cured, remove the drive module from the bonding fixture, completing the adhesive sealing of the laminated glass cloth board on top of the drive module. Under high-pressure impact conditions, the pressure resistance of the laminated glass cloth board and sealant reduces the deformation of the drive module's top cover under high pressure.

[0012] Furthermore, in step S1, the method of bonding the laminated glass cloth board above the drive module is as follows: apply sealant to the surface of the laminated glass cloth board, with a coating height greater than 1mm, and then place the laminated glass cloth board on the top cover of the drive module.

[0013] Furthermore, in step S1, a protruding positioning baffle is provided on the lower surface of the laminated glass cloth board; the positioning baffle is engaged on the four sides of the drive module to ensure that the laminated glass cloth board is accurately positioned on the top cover of the drive module.

[0014] Furthermore, in step S2, the bonding fixture includes: a base plate, a positioning post, an upper cover plate, and a limiting screw.

[0015] Furthermore, four positioning posts are vertically arranged on the upper surface of the base plate; the upper cover plate is fastened to the positioning posts by limiting screws, and the upper cover plate can be pressed down by tightening the limiting screws.

[0016] Furthermore, in step S2, the drive module and the laminated glass cloth are placed between the upper cover plate and the bottom plate, so that when the upper cover plate moves downward, it can press down the laminated glass cloth and squeeze the sealant, thereby adjusting the thickness of the sealant.

[0017] Furthermore, in step S2, a positioning block is fixedly installed on the upper surface of the base plate. The positioning block is used to limit the displacement of the upper cover plate. When the upper cover plate contacts the positioning block, it cannot continue to move, thereby limiting the minimum thickness of the sealant.

[0018] Furthermore, in step S3, a pressure plate is fixedly installed on the lower surface of the upper cover plate, and the pressure plate contacts the upper surface of the laminated glass cloth plate.

[0019] Furthermore, in step S3, the method of adjusting the sealant thickness by moving the upper cover plate downward is as follows: as the limit screw is tightened, the pressure plate will gradually press the laminated glass cloth plate onto the top cover of the drive module, and the excess sealant will be squeezed out from the periphery of the laminated glass cloth plate, thereby controlling the sealant thickness.

[0020] Furthermore, the thickness of the laminated glass cloth sheet is 2 to 2.5 mm.

[0021] Furthermore, the physical properties of the laminated glass cloth are as follows: elastic modulus of 24000MPa, density of 1.8g / cm3, and Poisson's ratio of 0.38.

[0022] In step S4, after bonding is completed, the thickness of the sealant is controlled between 0.3mm and 0.5mm.

[0023] The technical solution of this invention can achieve at least one of the following effects:

[0024] 1. The bonding method of the drive module to the laminated glass cloth board of the present invention involves bonding an epoxy laminated glass cloth board to the top cover of the drive module. Using bonding fixtures and a bonding process involving the laminated glass cloth board and sealant, the solder joints of the drive board above the drive module are guaranteed not to short-circuit, and the sealant can be well cured. This ensures consistent and reliable bonding quality and greatly enhances the drive module top cover's ability to resist high-pressure impacts. Under high-pressure impact conditions, the compressive strength of the laminated glass cloth board and sealant reduces the deformation of the drive module top cover under high pressure.

[0025] 2. In order to maintain good airtightness between the laminated glass cloth board, the sealant and the top cover of the module, the bonding method of the drive module of the present invention is designed with a special bonding fixture for bonding the laminated glass cloth board and the drive module. The fixture can position and press the laminated glass cloth board and the drive module together, and maintain a certain thickness of sealant. By squeezing, the internal sealant is filled evenly, which can ensure good consistency in the production of drive module components.

[0026] 3. This invention provides a bonding method for bonding a laminated glass cloth sheet to a drive module. This method prevents deformation of the drive module housing and product failure under high-pressure impact. After sealing, the first-pass yield is high, eliminating the need for rework. The laminated glass cloth sheet, as a pressure-resistant cover, is a non-metallic material, and its insulation properties effectively prevent short circuits in the drive board of the drive module.

[0027] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

Detailed Implementation

[0041] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0042] Example 1

[0043] A specific embodiment of the present invention discloses a bonding method for bonding a laminated glass cloth sheet to a drive module. The method employs bonding fixtures to bond the laminated glass cloth sheet to the drive module, such as... Figure 1 As shown, it includes the following steps:

[0044] Step S1: Apply a certain thickness of sealant to the laminated glass cloth board 3 and place it on the top cover of the drive module 1;

[0045] Step S2: Install the drive module 1 onto the base plate 2 of the bonding fixture;

[0046] Step S3: Press down the upper cover plate 7 of the bonding fixture to press the laminated glass cloth board 3 tightly onto the upper surface of the drive module 1; and adjust the thickness of the sealant between the laminated glass cloth board 3 and the drive module 1 by controlling the amount of pressure of the upper cover plate 7.

[0047] Step S4: After the laminated glass cloth board 3 is pasted, the drive module 1 is left to stand and cure. After the sealant has cured, the drive module 1 is removed from the bonding fixture, and the adhesive sealing of the laminated glass cloth board 3 on the top of the drive module 1 is completed.

[0048] Under high-pressure impact conditions, the deformation of the top cover of the drive module 1 under high pressure is reduced by the compressive resistance of the laminated glass cloth 3 and the sealant.

[0049] Furthermore, in step S1, the method of bonding the laminated glass cloth board 3 above the drive module 1 is as follows: apply sealant to the surface of the laminated glass cloth board 3, with a coating height greater than 1mm, and then place the laminated glass cloth board 3 on the top cover of the drive module 1.

[0050] Further, in step S4, after bonding, the thickness of the sealant is controlled between 0.3mm and 0.5mm. Preferably, after the laminated glass cloth board 3 is pressed into place, the thickness of the sealant is 0.4mm.

[0051] Furthermore, in step S1, a protruding positioning baffle is provided on the lower surface of the laminated glass cloth board 3; the positioning baffle is engaged on the four sides of the drive module 1, so that the laminated glass cloth board 3 is accurately positioned on the top cover of the drive module 1.

[0052] Preferably, the positioning baffles are four flat plates or L-shaped plates perpendicular to the laminated glass cloth plate 3, and the gaps between the positioning baffles are used to accommodate the drive module 1. In practice, when the positioning baffles are flat plates, the four positioning baffles are respectively set to fit the four sides of the drive module 1; when the positioning baffles are L-shaped plates, the positioning baffles fit the four corners of the drive module 1.

[0053] Furthermore, to facilitate the overflow of sealant, a positioning baffle is provided at the edge of the laminated glass cloth board 3, and the length of the positioning baffle is less than one-tenth of the length / width of the drive module 1.

[0054] The bonding method of this invention is used to reduce the deformation of the drive module top cover under high air pressure by utilizing the compressive strength of the laminated glass cloth and sealant. This requires good airtightness between the laminated glass cloth, sealant, and module top cover. Therefore, a special tooling for bonding the drive module to the laminated glass cloth is designed. This tooling can position and compress the laminated glass cloth, maintain a certain thickness of sealant, and ensure uniform filling of the internal sealant through compression, thus guaranteeing good consistency in the production of drive module components.

[0055] In one specific embodiment of the present invention, such as Figure 2 , Figure 3 As shown, the bonding fixture includes: a base plate 2, positioning posts 5, an upper cover plate 7, and limiting screws 9; four positioning posts 5 are vertically arranged on the upper surface of the base plate 2; the upper cover plate 7 is fastened to the positioning posts 5 by the limiting screws 9, and the upper cover plate 7 can be pressed down by tightening the limiting screws 9; the drive module 1 and the laminated glass cloth plate 3 are placed between the upper cover plate 7 and the base plate 2, so that when the upper cover plate 7 moves downward, it can press down the laminated glass cloth plate 3 and squeeze the sealant, thereby adjusting the thickness of the sealant.

[0056] Specifically, mounting portions are provided at the four corners of the upper cover plate 7, and mounting portions are provided with mounting holes for engaging with limit screws 9.

[0057] In this embodiment, the upper end face of the positioning post 5 is provided with a first threaded hole extending along its own axis; the limiting screw 9 can be screwed into the first threaded hole; in practice, the upper cover plate 7 is placed above the laminated glass cloth plate 3, and the limiting screw 9 passes through the mounting holes at the four corners of the upper cover plate 7 and is screwed into the first threaded hole; by tightening the limiting screw 9, the upper cover plate 7 can be gradually moved down, thereby pressing down the laminated glass cloth plate 3 through the upper cover plate 7 and squeezing the sealant so that the sealant is evenly distributed between the laminated glass cloth plates 3 of the drive module 1 and maintains good airtightness.

[0058] Furthermore, in step S3, a positioning block 4 is fixedly installed on the edge of the upper surface of the base plate 2. The positioning block 4 is used to limit the displacement of the upper cover plate 7. When the upper cover plate 7 contacts the positioning block 4, it cannot continue to move, thereby limiting the minimum thickness of the sealant.

[0059] Furthermore, a pressure plate 8 is fixedly installed on the lower surface of the upper cover plate 7, and contacts the upper surface of the laminated glass cloth board 3 through the pressure plate 8, such as... Figure 3 As shown.

[0060] Furthermore, in step S3, the way the upper cover plate 7 moves down to adjust the thickness of the sealant is as follows: as the limit screw 9 is tightened, the pressure plate 8 will gradually press the laminated glass cloth plate 3 onto the top cover of the drive module 1, and the excess sealant will be squeezed out from the periphery of the laminated glass cloth plate 3, thereby controlling the thickness of the sealant.

[0061] Furthermore, the thickness of the laminated glass cloth board 3 is 2 to 2.5 mm.

[0062] Furthermore, the physical properties of the laminated glass cloth board 3 are as follows: elastic modulus of 24000MPa, density of 1.8g / cm3, and Poisson's ratio of 0.38.

[0063] Furthermore, after the laminated glass cloth board 3 is bonded to the drive module 1 using the bonding method of the present invention, a high-pressure test is conducted on the packaged drive module 1 to verify its high-pressure resistance. Specifically, a static pressure test is conducted on the drive module. The drive module is placed in a pressure vessel, and the insulation resistance between the module pins and the housing is monitored in real time during the pressure increase. Under an external air pressure of 0.7 MPa, the resistance between the pins and the housing of the drive module 1 remains infinite, indicating good high-pressure resistance.

[0064] In one specific embodiment of the present invention, the sealant material selected is RTV283-01 high-temperature resistant sealant. RTV283-01 high-temperature resistant sealant is a two-component silicone rubber. This sealant has adhesive properties to both metallic and non-metallic materials, and can firmly bond the drive module and the laminated glass cloth board together. Furthermore, it can cure without contact with air. RTV283-01 high-temperature resistant sealant does not require contact with air or liquid; it cures solely through the reaction between components A and B. This allows it to bond the cover plate of the drive module 1 and the laminated glass cloth board 3, while also isolating the drive module 1 from air, maintaining its airtightness, and thus ensuring high reliability.

[0065] Example 2

[0066] In a specific embodiment of the present invention, based on Embodiment 1, an improved design for the bonding method of Embodiment 1 is provided:

[0067] In this embodiment, the upper cover plate 7 of the bonding fixture is not connected to the positioning post 5 by a limiting screw 9. For example... Figure 4 As shown, in this embodiment, the four positioning posts 5 are smooth cylinders; the upper cover plate 7 is fitted onto the four positioning posts 5 through mounting holes at the four corners, and can slide up and down relative to the positioning posts 5; a pressure plate 8 is fixedly installed below the upper cover plate 7, and the two are connected by screws or are an integral structure.

[0068] Furthermore, in this embodiment, a pressing fixture is provided to press down the upper cover plate 7.

[0069] like Figure 5 , Figure 6 As shown, the press-fitting fixture includes: a positioning top plate 10, a support column 11, a positioning base 12, a linear actuator 13, a transmission mechanism, a drive rod 21, a threaded sleeve 22, a lower pressure plate 23, and a limit frame 24.

[0070] Specifically, such as Figure 5 As shown, the linear actuator 13 is fixedly mounted on the positioning top plate 10, and the linear actuator 13 converts linear displacement into rotational motion output through a transmission mechanism, driving the drive rod 21 to rotate. The upper end of the drive rod 21 is rotatably mounted below the positioning top plate 10 via a bearing, and the lower end of the drive rod 21 can be screwed into the threaded sleeve 22 via a thread. When the drive rod 21 rotates under the drive of the transmission mechanism, it can unscrew from the threaded sleeve 22, thereby adjusting the overall length of the drive rod 21 and the threaded sleeve 22. Specifically, the lower end of the drive rod 21 is provided with an external thread, and the threaded sleeve 22 has a second threaded hole inside; the lower end of the drive rod 21 is screwed into the second threaded hole via the external thread.

[0071] Furthermore, a lower pressure plate 23 is fixedly installed at the lower end of the threaded sleeve 22. The lower pressure plate 23 has a sleeve part at each of its four corners, and the sleeve part has a sleeve hole that can be sleeved with the positioning post 5 of the bonding fixture.

[0072] Furthermore, a rectangular limiting frame 24 is provided on the positioning base 12; the inner cavity size of the limiting frame 24 is the same as the size of the bonding fixture; thus, the base plate 2 of the bonding fixture can be placed in the limiting frame 24.

[0073] The implementation principle is as follows: the base plate 2 of the bonding fixture is nested in the limiting frame 24, and multiple positioning pins 5 pass through multiple socket holes on the lower pressure plate 23, restricting the deflection movement of the lower pressure plate 23; when the drive rod 21 rotates relative to the lower pressure plate 23, it can screw into or out of the threaded sleeve 22, thereby driving the lower pressure plate 23 to move up or down along the axis of the positioning pins 5; when the lower pressure plate 23 moves down, it can press down the upper cover plate 7 and the laminated glass cloth plate 3, thereby achieving thickness control of the sealant and gas discharge.

[0074] In step S3, the method of pressing down multiple sets of bonding fixtures simultaneously using the pressing fixture is as follows:

[0075] Step S31: Move the lower pressure plate 23 upward by the linear actuator 13 to reserve filling space for the bonding fixture;

[0076] Step S32: [The following text appears to be a separate, unrelated section:] ... Figure 4 The bonding fixture shown is placed in the limiting frame 24 to prevent the bonding fixture from rotating; and the limiting effect of the limiting frame 24 makes the positioning post 5 of the bonding fixture aligned with the socket on the lower pressure plate 23.

[0077] Step S33: The linear actuator 13 drives the drive rod 21 to rotate through the transmission mechanism. During the rotation of the drive rod 21, it is unscrewed from the threaded sleeve 22, which increases the length of both. As a result, the lower pressure plate 23 moves down and is sleeved on the positioning post 5.

[0078] Step S34: The lower pressure plate 23 continues to move down and press down the upper cover plate 7 of the bonding fixture, and then the pressure plate 8 presses down the laminated glass cloth board 3 so that the sealant is pressed evenly and squeezed out between the laminated glass cloth board 3 and the drive module 1 until the upper cover plate 7 contacts the upper surface of the positioning block 4, thus completing the pressing process.

[0079] In one specific embodiment of the present invention, the transmission mechanism of the pressing fixture includes: a translation plate 14, a sliding rack 15, a first gear 16, a slide rail 17, a rotating shaft 18, a drive gear 19, and a second gear 20, as shown below. Figure 5 , Figure 6 As shown.

[0080] Specifically, such as Figure 5 As shown, the translation plate 14 is fixedly installed at the end of the output shaft of the linear driver 13 and can move linearly under the drive of the linear driver 13.

[0081] Specifically, such as Figure 5 , Figure 6 As shown, one or more sliding racks 15 are fixedly installed on the side of the translation plate 14; the first gear 16 is rotatably installed on the positioning top plate 10 via the rotating shaft 18 and meshes with the sliding rack 15; the second gear 20 is fixedly installed below the rotating shaft 18, and the drive gear 19 is fixedly installed on the outside of the drive rod 21, and the second gear 20 meshes with the drive gear 19.

[0082] Specifically, the rotating shaft 18 is connected to the positioning top plate 10 via a bearing.

[0083] Specifically, one or more slide rails 17 are provided on the upper surface of the positioning top plate 10. The slide rails 17 slide in engagement with the bottom of the sliding rack 15 to assist in the linear sliding of the sliding rack 15. Furthermore, when the sliding rack 15 slides linearly along the slide rails 17, it can simultaneously mesh with multiple first gears 16, driving the multiple first gears 16 to rotate synchronously, such as... Figure 5 As shown.

[0084] In step S32, multiple limiting frames 24 are arranged side by side on the positioning base 12 for mounting multiple sets of adhesive fixtures, such as... Figure 5 As shown.

[0085] Preferably, multiple sets of first gear 16, rotating shaft 18, drive gear 19, and second gear 20 are arranged on the positioning top plate 10; multiple first gears 16 mesh with sliding rack 15 simultaneously, and can rotate synchronously when the linear actuator 13 outputs linear displacement, thereby driving multiple drive rods 21 to rotate synchronously, realizing synchronous pressing of multiple sets of bonding fixtures, and thus realizing the bonding process of laminated glass cloth sheets of multiple drive modules 1, improving work efficiency.

[0086] In step S33, the process of the linear actuator 13 driving multiple pressure plates 23 to press down synchronously is as follows:

[0087] Step S331: The linear driver 13 outputs linear displacement, which drives the translation plate 14 and multiple sliding racks 15 to move linearly synchronously;

[0088] Step S332: Multiple sliding racks 15 mesh with multiple first gears 16 to drive the first gears 16 to rotate, and the second gear 20 and the first gear 16 rotate synchronously under the drive of the rotating shaft 18;

[0089] Step S333: Multiple second gears 20 mesh with multiple drive gears 19 to drive the drive gears 19 and drive rods 21 to rotate. When the multiple drive rods 21 rotate, they screw into or out of the threaded sleeves 22, ultimately achieving synchronous up and down displacement of multiple lower pressure plates 23.

[0090] In this embodiment, the displacement of the upper cover plate 7 of the bonding fixture is driven by the pressing fixture. Compared with the driving method of rotating the limiting screw 9 in Embodiment 1, the operation is simpler and can maintain the overall stable downward movement of the upper cover plate 7. Rotating multiple limiting screws 9 makes it difficult to ensure that multiple limiting screws press down on the upper cover plate 7 at the same time. If the upper cover plate 7 tilts, it may affect the bonding effect of the laminated glass cloth board.

[0091] In this embodiment, the lower pressure plate 23 is moved downward by the relative rotation of the drive rod 21 and the threaded sleeve 22; at the same time, multiple sliding racks 15 drive multiple first gears 16 to rotate, thereby synchronously driving multiple drive rods 21. Finally, the upper cover plate 7 of multiple sets of bonding fixtures of multiple lower pressure plates 23 is pressed down synchronously, realizing the process of bonding laminated glass cloth boards of multiple drive modules 1 at one time. After pressing, multiple drive modules can be statically cured at the same time, saving production and processing time.

[0092] Example 3

[0093] In one specific embodiment of the present invention, the bonding method in Example 1 is further improved:

[0094] In this embodiment, to control the distance between the pressed laminated glass cloth board 3 and the driving module 1, and to adapt to the operation steps of bonding the laminated glass cloth board 3 to driving modules 1 of different sizes, an adjustment mechanism for adjusting the height of the positioning block 4 is provided on the base plate 2. Specifically, as shown... Figure 7 As shown, two sets of adjustment mechanisms are arranged side by side on both sides of the base plate 2. Each set of adjustment mechanisms includes two sets of symmetrically arranged adjustment components. The adjustment components include: a stepped adjustment block 205, an adjustment screw 206, and a fixing block 207. The fixing block 207 is fixedly installed above the base plate 2, and a third threaded hole is provided in the middle of the fixing block 207. The adjustment screw 206 is screwed into the third threaded hole. The end of the adjustment screw 206 is rotatably connected to a stepped adjustment block 205 through a bearing. The lower surface of the stepped adjustment block 205 is in contact with the upper surface of the base plate 2.

[0095] Furthermore, the positioning block 4 rests on the step of the step adjustment block 205. By adjusting the distance between the two opposing step adjustment blocks 205, steps of different heights can be switched to support the positioning block 4. Preferably, the step height between the multiple steps of the step adjustment block 205 is 0.2mm.

[0096] In step S3, by adjusting the height of the positioning block 4, the adhesive bonding fixture can be adjusted to be suitable for the adhesive bonding process of the drive module 1 with different size parameters, and the thickness of the sealant after the drive module 1 and the laminated glass cloth board 3 are bonded can be adjusted.

[0097] Specifically, in step S3, the height adjustment method of positioning block 4 is as follows:

[0098] Step S301: Rotate the adjusting screw 206 so that it can move along the axial direction of the third threaded hole, thereby pulling the stepped adjusting block 205 to slide on the upper surface of the base plate 2;

[0099] Step S302: By rotating the adjusting screws 206 of the two sets of symmetrically arranged adjusting components, the two opposing stepped adjusting blocks 205 can be moved, thereby adjusting the two opposing stepped adjusting blocks 205 to move closer or further apart from each other;

[0100] Step S303: After the distance between the two step adjustment blocks 205 is changed, different heights of steps on the step adjustment blocks 205 can be switched to support the positioning block 4, thereby adjusting the height of the positioning block 4.

[0101] Furthermore, in order to quickly clean up the sealant squeezed out after the upper cover plate 7 presses down the laminated glass cloth plate 3, in this embodiment, a scraper is provided to remove the overflowing sealant.

[0102] In this embodiment, a first groove 201 and a second groove 203 for mounting the scraper 208 are provided on the base plate 2; for example Figure 7 , Figure 8 As shown.

[0103] Specifically, two sets of first slide grooves 201 are symmetrically arranged on the upper and lower sides of the base plate 2; two first slide grooves 201 in each set are arranged side by side along the length of the base plate 2; two sets of second slide grooves 203 are symmetrically arranged on the upper and lower sides of the base plate 2; two first slide grooves 201 in each set are arranged side by side along the length of the base plate 2; the first slide grooves 201 are perpendicular to the long side of the base plate 2, and a first pull rod hole 202 extending to the outer side of the base plate 2 is opened on the side of the first slide grooves 201; the second slide grooves 203 are perpendicular to the short side of the base plate 2, and a second pull rod hole 204 extending to the outer side of the base plate 2 is opened on the side of the second slide grooves 203.

[0104] like Figure 8 As shown, two connecting plates 209 are arranged side by side below the scraper 208, and a pull rod 210 is fixedly installed on the side of the two connecting plates 209.

[0105] Specifically, the scraper 208 includes: a first scraper 2081 and a second scraper 2082, such as Figure 9 As shown.

[0106] The connecting plate 209 and the pull rod 210, which are fixedly connected to the first scraper 2081, are respectively disposed in the first slide groove 201 and the first pull rod hole 202. Similarly, the connecting plate 209 and the pull rod 210, which are fixedly connected to the first scraper 2081, are respectively disposed in the second slide groove 203 and the second pull rod hole 204. The connecting plate 209 can slide in the first slide groove 201 / second slide groove 203, and the end of the pull rod 210 extends out of the outer side of the bottom plate 2.

[0107] Preferably, the height of the scraper 208 is lower than the upper surface of the drive module 1, or the height of the scraper 208 is flush with the height of the top cover of the drive module 1.

[0108] Preferably, a return spring 211 is sleeved on the outside of the pull rod 210; one end of the return spring 211 abuts against the connecting plate 209, and the other end abuts against the side of the first slide groove 201 / second slide groove 203. The spring force of the return spring 211 is used to push the scraper 208 to move towards the drive module 1, and then to fit against the outer side of the drive module 1. When the adhesive between the top cover and the laminated glass cloth board 3 overflows, the overflowing adhesive flows onto the outer side of the scraper 208.

[0109] Preferably, the length of the first scraper 2081 is greater than the length of the second scraper 2082; the first scraper 2081 abuts against the long side of the drive module 1 under the action of the return spring 211; the second scraper 2082 abuts against the short side of the drive module 1 under the action of the return spring 211; and the second scraper 2082 is disposed between the two first scrapers 2081, such as... Figure 9 As shown.

[0110] In practical applications, the edge of the scraper 208 is partially cut off so that it can avoid the positioning baffle at the edge of the laminated glass cloth board 3.

[0111] In step S4, before allowing the adhesive to cure, it is necessary to remove any overflowing adhesive from the side of the drive module 1.

[0112] Specifically, in this embodiment, the method of scraping off the adhesive using a scraper 208 is as follows:

[0113] Step S401: Before the upper cover plate 7 presses the laminated glass cloth plate 3, the first scraper 2081 and the second scraper 2082 are pressed against the side of the drive module 1 by the elastic force of the return spring 211.

[0114] Step S402: During the pressing of the laminated glass cloth board 3, the sealant overflows onto the outer side of the first scraper 2081 and the second scraper 2082 (the side where the connecting plate 209 is set).

[0115] Step S403: Pull the lever 210 outward to make the connecting plate 209 slide in the first slide groove 201 / second slide groove 203; and drive the first scraper 2081 and the second scraper 2082 to slide outward to the base plate 2 through the connecting plate 209; the first scraper 2081 can scrape off the glue overflowing from the long side of the drive module 1; the second scraper 2082 can scrape off the glue overflowing from the short side of the drive module 1.

[0116] In this embodiment, by setting an adjustment mechanism to adjust the height of the positioning block 4, the bonding fixture can be adapted to the bonding work of laminated glass cloth 3 of different models of drive modules 1; and the thickness of the sealant after pressing can be adjusted according to the requirements of resisting high pressure impact.

[0117] In this embodiment, by providing a relatively sliding scraper 208 on the base plate 2, the overflowing adhesive can be scraped off after pressing, which simplifies the subsequent process of removing excess adhesive and improves work efficiency.

[0118] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
