Description

[0001] This application is a divisional application, with the original application number 202411386848.2, application date 2024.09.30, and the invention title: Pressing tooling, pressing method and preparation method of handheld ultrasound diagnostic instrument. Technical Field

[0002] This invention relates to the field of ultrasonic equipment manufacturing, and more specifically, to a pressing fixture, a pressing method, and a method for preparing a handheld ultrasonic diagnostic instrument. Background Technology

[0003] A handheld ultrasound diagnostic device is a portable medical device used for ultrasound examinations and diagnoses. It typically consists of a handheld probe and a display screen. The user scans the body surface with the probe and then views the ultrasound image on the screen. Handheld ultrasound diagnostic devices are portable, easy to carry, and easy to use, making them very useful in special situations such as emergency rooms, operating rooms, and ICUs. Furthermore, they can be used in situations where routine ultrasound examinations are inconvenient.

[0004] The ultrasound probe is the core component of a handheld ultrasound diagnostic instrument. It is responsible for emitting and receiving ultrasound waves, converting the sound wave signals from the examination area into electrical signals, and then transmitting them to the main unit for processing. The shape and size of the probe will vary depending on the different examination sites and applications.

[0005] The inventors discovered that in the manufacturing process of ultrasonic probes, in order to ensure the product's high temperature resistance, low temperature resistance, and waterproof properties, electronic sealant needs to be applied to the cavity of the ultrasonic probe product. To ensure the sealing effect, it is usually difficult to control the specific amount of glue used. If there is too little glue, the glue will not be properly applied. Therefore, in actual operation, the amount of glue used is often slightly more, and then some glue overflows through the pressing of the pressing fixture.

[0006] Therefore, in order to avoid glue overflow during the pressing process when the amount of glue used cannot be controlled, this is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0012] Optionally, after the negative pressure state ends, the connecting block moves downward along the mating groove, causing the inner core to move downward along the first inner cavity, so that the first inner cavity and the second inner cavity are in a positive pressure state.

[0013] Optionally, a second protrusion extends from both sides of the first protrusion, and a second groove is provided on the inner sidewall of the second protrusion. The second groove forms the second inner cavity and communicates with the first groove. Slides extend from both sides of the inner core. The slides are configured to cooperate with and slide in the first groove so that the slides can move up and down along the side seam.

[0014] Optionally, the top of the sealing plate is provided with a lifting member, and the top of the sealing box is provided with a second opening; the lifting member extends out of the sealing cavity along the second opening, and the lifting member is pulled to make the sealing plate slide up and down along the sealing cavity; The sealing structure is also provided with a positioning rod, which is movably connected to the body so that the sealing structure can move up and down along the pressing station.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product 100 is usually placed during use, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0028] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0029] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0031] In this embodiment, the product 100 pressed by the pressing fixture 010 is a handheld ultrasound diagnostic instrument, namely a smart wireless handheld color ultrasound. It is a special design made for the electronic sealant filling treatment inside the cavity of the smart wireless handheld color ultrasound. Other devices or instruments do not have the requirement to fill the ultrasound probe with sealant, so this pressing fixture 010 cannot be reused.

[0032] Please refer to Figure 1 and Figure 2 For ease of understanding and illustration, Figure 2 The line at the seam position 120 has been thickened.

[0033] In this embodiment, the outer casing 110 of the handheld ultrasound diagnostic instrument includes an upper casing 111, a lower casing 112, and at least one probe casing 113. The upper casing 111 and the lower casing 112 are fitted together and fastened together by a snap-fit ​​structure. At least one probe casing 113 is detachably mounted at the ends of the upper casing 111 and the lower casing 112. That is, the part where the probe casing 113 connects to the upper casing 111 and the lower casing 112 is the seam position 120. Since the casing has a rectangular structure and a certain curvature, the seam position 120 includes a planar seam 121 and a side seam 122. The planar seam 121 is located on the upper surface of the casing, and the side seam 122 is located on both sides of the casing.

[0034] In an alternative embodiment, the handheld ultrasound diagnostic instrument may include a probe housing 113, which is mounted on the left or right end of the upper housing 111 and the lower housing 112 via a detachable structure.

[0035] Of course, the ultrasonic device may also include two probe housings 113, which are respectively installed at the left and right ends of the upper housing 111 and the lower housing 112. That is, the corresponding ultrasonic probe potting area is spliced ​​by at least two parts, and a seam position 120 is left on the outer surface of the outer shell 110. The outer shell 110, which consists of the upper housing 111, the lower housing 112 and at least one probe housing 113, forms a mounting cavity inside, which is used to install electronic circuit structures.

[0036] Understandably, to ensure the high-temperature resistance, low-temperature resistance, and waterproof properties of product 100, the connection between probe housing 113 and upper housing 111 and lower housing 112 requires potting. Given the small housing of products like handheld ultrasound diagnostic instruments, the limited space for potting means the adhesive 130 will expand at different temperatures, making it difficult to control the amount used. Insufficient adhesive 130 will result in incomplete potting. Therefore, to ensure a proper seal, adhesive 130 is usually added in slightly excess. The pressing tool 010 then causes some adhesive 130 to overflow, which is then cleaned from the surface of product 100. Because the outer shell 110 of the ultrasonic equipment has a certain curvature and is not flat, glue 130 will overflow at the flat joint 121 on its upper surface, and the glue 130 will flow under the action of gravity and slope; at the same time, because the sealant will shrink after solidification, if the glue 130 at the flat joint 121 on the upper surface of the outer shell 110 flows away, there will be insufficient glue filling at the part that needs to be filled after the glue 130 solidifies.

[0037] Therefore, the handheld ultrasound diagnostic instrument produced by this pressing not only has the problem of glue overflow, but also requires a subsequent cleaning process to clean the glue 130 that has overflowed on the surface of the product 100, making the process cumbersome and inefficient.

[0038] At least one embodiment provides a pressing tool 010 for pressing a handheld ultrasound diagnostic instrument, enabling the handheld ultrasound diagnostic instrument to be stably closed, achieving a perfect fit between the shell of the handheld ultrasound diagnostic instrument and the sealant, solving the problems of glue overflow and expansion, and avoiding the problem of insufficient amount of glue 130 on the top surface of the handheld ultrasound diagnostic instrument due to volume reduction after the glue 130 solidifies.

[0039] Please refer to Figure 3 This embodiment proposes a pressing fixture 010, including a body 200 and a sealing structure 300. The body 200 has a pressing station 201 for placing a product 100, and the product 100 has a seam position 120. The sealing structure 300 is disposed on the body 200, and has a sealing cavity 301 inside. The sealing cavity 301 is disposed opposite to the pressing station 201 so that the product 100 is located inside the sealing cavity 301. The sealing structure 300 has an inner cavity, which is disposed opposite to and close to the seam position 120. The sealing structure 300 is used to adjust the pressure state of the sealing cavity 301 and the inner cavity.

[0040] Understandably, when product 100 is placed on the pressing station 201, the sealing cavity 301 is under positive pressure. The sealing structure 300 adjusts the pressure of the sealing cavity 301 and the inner cavity to a negative pressure state, making the adhesive 130 at the joint position 120 more fluid, which promotes the expulsion of air bubbles in the adhesive 130. At the same time, the adhesive 130 overflowing at the joint position 120 flows into the inner cavity under negative pressure, preventing the fluid adhesive 130 from flowing out along the joint position 120. This avoids the problem of insufficient adhesive 130 on the upper surface of product 100 due to volume reduction after solidification, thus maintaining the amount of adhesive 130 at the joint position 120 of product 100 and ensuring the overall shaping effect of product 100.

[0041] In this embodiment, the pressing tool 010 includes a body 200.

[0042] In this embodiment, please refer to Figure 4 The main body 200 includes a U-shaped bracket 210 and two limiting plates 220. The U-shaped bracket 210 includes a base plate 211 and two support plates 212 respectively disposed on both sides of the base plate 211. Each support plate 212 has a plurality of spaced-apart mounting holes 2121. The limiting plates 220 are L-shaped. The vertical ends of the limiting plates 220 are fixed to the mounting holes 2121 by fasteners. The parallel ends of the limiting plates 220 have a plurality of spaced-apart first adjustment holes 221, which connect to positioning elements for positioning the sealing box 310.

[0043] Please see below. Figure 8 A pressing station 201 is set on the base plate 211 accordingly.

[0044] In this embodiment, in order to accommodate the width and height of different products 100, at least two sliding members 230 are provided at the pressing station 201 of the base plate 211.

[0045] In this embodiment, please refer to Figure 3 and Figure 4 The pressing station 201 is equipped with four symmetrically arranged L-shaped sliding members 230; the base plate 211 of the body 200 is equipped with four symmetrically arranged sliding grooves 2111, and the parallel ends of the four sliding members 230 are slidably connected to the four sliding grooves 2111 respectively, so that the size of the pressing station 201 is adjustable. Among them, the sliding members 230 are equipped with multiple spaced second adjustment holes 231, and the sliding members 230 are fixed to the base plate 211 by means of fixing members passing through the sliding grooves 2111 and the second adjustment holes 231.

[0046] In this embodiment, the pressing tool 010 includes a sealing structure 300.

[0047] In this embodiment, the sealing structure 300 is disposed on the body 200, and the sealing structure 300 is provided with a sealing cavity 301. The sealing cavity 301 is disposed relative to the pressing station 201 so that the product 100 is located in the sealing cavity 301. The sealing structure 300 is provided with an inner cavity, which is disposed relative to and close to the joint position 120. The sealing structure 300 is used to adjust the pressure state of the sealing cavity 301 and the inner cavity.

[0048] The sealing structure 300 can adjust the pressure state of the sealing cavity 301 and the inner cavity, namely the positive pressure state and the negative pressure state.

[0049] In an optional embodiment, the pressure state of the sealing structure 300 can be adjusted by a vacuum device.

[0050] In this embodiment, the sealing structure 300 includes a sealing box 310 and a sealing plate 320; the sealing box 310 is provided with a sealing cavity 301, and the interior of the sealing box 310 is provided with an inner cavity; the sealing plate 320 is disposed in the sealing cavity 301, and the sealing plate 320 slides along the sealing cavity 301 and the inner cavity to adjust the pressure state of the sealing cavity 301 and the inner cavity to a negative pressure state.

[0051] In this embodiment, please refer to Figure 5 and Figure 6 The sealing box 310 has a rectangular box structure with an opening, forming a sealing cavity 301. A first protrusion 312 is provided on the inner top wall of the sealing box 310, and a first inner cavity 3121 is provided inside the first protrusion 312. A first groove is provided at the bottom of the first protrusion 312, forming the first inner cavity 3121. The first inner cavity 3121 is positioned opposite the planar joint 121 on the upper surface of the outer shell 110.

[0052] Furthermore, a second protrusion 313 extends from both sides of the first protrusion 312. The inner wall of the second protrusion 313 is provided with a second groove, which forms a second inner cavity 3131. The second groove communicates with the first groove. The second inner cavity 3131 is disposed opposite to both sides of the first inner cavity 3121 and opposite to the side seams 122 on both sides of the outer shell 110.

[0053] Please refer to Figure 6 The inner and / or outer sidewalls of the first protrusion 312 are provided with a mating groove 3122 that communicates with the first groove. The mating groove 3122 is vertically arranged along the extension direction of the first inner cavity 3121. The mating groove 3122 is used to avoid the connecting block 3211 so that the sealing plate 320 can drive the inner core 321 to move up and down along the first inner cavity 3121.

[0054] In this embodiment, the first protrusion 312 is a protruding structure with an inwardly concave arc shape to fit the planar seam 121 on the upper surface of the outer shell 110. Of course, in optional embodiments, the first protrusion 312 can also be a straight plate structure, a multi-arc structure, etc., as long as the first protrusion 312 can fit with the seam position 120 of the product 100.

[0055] In this embodiment, please refer to Figure 5 and Figure 6 To prevent the sealing plate 320 from getting stuck and to allow it to move up and down more smoothly, a third protrusion 314 is provided on the inner top wall of the sealing box 310. The position of the third protrusion 314 is symmetrical to that of the first protrusion 312. Of course, in an optional embodiment, the structure of the third protrusion 314 can also be the same as that of the first protrusion 312 to facilitate simultaneous operation on multiple planar seams 121 on the upper surface of the outer shell 110.

[0056] The top of the sealing box 310 is provided with a second opening 315; the lifting member 325 extends out of the sealing cavity 301 along the second opening 315, and the lifting member 325 is lifted so that the sealing plate 320 slides up and down along the sealing cavity 301.

[0057] The top of the sealing box 310 is provided with two positioning rods 316 on both sides of the second opening 315. The positioning rods 316 are movably connected to the first adjustment hole 221 of the body 200, so that the sealing structure 300 can move up and down along the pressing station 201. The positioning rods 316 are used to position the sealing box 310 on the body 200. Optionally, the positioning rods 316 are threaded positioning screws.

[0058] It is worth mentioning that, in this embodiment, the height of the first protrusion 312 should be such that the first inner cavity 3121 is close to the plane joint 121 on the upper surface of the product 100, so that the adhesive 130 can be drawn into the first inner cavity 3121 under negative pressure; or the first inner cavity 3121 can directly abut against the plane joint 121 on the upper surface of the product 100, please refer to Figure 10 .

[0059] In this embodiment, please refer to Figure 7 The sealing plate 320 is a rectangular plate and is disposed within the sealing cavity 301. The sealing plate 320 is in contact with the inner wall of the sealing cavity 301 of the sealing box 310. The sealing plate 320 has a first arc-shaped opening 323 relative to the first protrusion 312 and a third arc-shaped opening 324 relative to the third protrusion 314. The first opening 323 is configured to cooperate with and be opposite to the first protrusion 312, meaning that the first protrusion 312 can move up and down along the inner side of the first opening 323.

[0060] Based on the above structure, the pressing tool 010 also needs to consider that the joint position 120 corresponds to the position of the glue-filling area during the pressing process; otherwise, it is not suitable for the pressing tool 010 and the corresponding pressing method.

[0061] The sealing plate 320 is provided with a lifting member 325 at the top, and the sealing box 310 is provided with a second opening 315 at the top; the lifting member 325 extends out of the sealing cavity 301 along the second opening 315, and the lifting member 325 is lifted so that the sealing plate 320 slides up and down along the sealing cavity 301.

[0062] In this embodiment, please refer to Figures 5-7 The sealing plate 320 is provided with an inner core 321. The inner core 321 is connected to the sealing plate 320 through a connecting block 3211. The connecting block 3211 moves up and down along the mating groove 3122 provided on the side wall of the first protrusion 312. The inner core 321 is located in the first opening 323 and is slidably disposed in the first inner cavity 3121.

[0063] The connecting block 3211 moves up and down along the mating groove 3122, causing the inner core 321 to move up and down along the first inner cavity 3121, so that the first inner cavity 3121 and the second inner cavity 3131 are in a negative pressure state.

[0064] After the negative pressure state ends, the connecting block 3211 moves downward along the mating groove 3122, causing the inner core 321 to move downward along the first inner cavity 3121, so that the first inner cavity 3121 and the second inner cavity 3131 are in a positive pressure state.

[0065] Understandably, please refer to Figure 8 , Figure 9 and Figure 10 The glued product 100 is placed on the positioning station, and the sealing plate 320 is moved upward by the lifting component 325. Since the product 100 occupies a large space in the sealing cavity 301, a slight negative pressure state is created inside the sealing cavity 301, which enhances the fluidity of the glue 130 at the joint 120 and promotes the expulsion of air bubbles in the glue 130. After the negative pressure state ends, the sealing plate 320 is moved downward by the lifting component 325, creating a positive pressure state inside the sealing cavity 301, which allows the glue 130 at the joint 120 to solidify quickly.

[0066] Further, please refer to Figure 5 A second protrusion 313 extends from both sides of the first protrusion 312. The inner wall of the second protrusion 313 is provided with a second groove, which forms a second inner cavity 3131. The second groove communicates with the first groove. Slide strips 3212 extend from both sides of the inner core 321. The slide strips 3212 are configured to cooperate with the first groove and slide to allow the slide strips 3212 to move up and down along the side joint 122.

[0067] Understandably, please refer to Figure 11 The first inner cavity 3121 of the first protrusion 312 is positioned relative to the planar joint 121 on the upper surface of the product 100. As the sealing plate 320 moves the inner core 321 together, the inner core 321 slides upward along the first inner cavity 3121, causing the pressure state between the first inner cavity 3121 and the planar joint 121 to be negative, thereby accelerating the overflow of the glue 130 at the planar joint 121. Since the first protrusion 312 abuts against the planar joint 121 on the upper surface of the product 100, the glue 130 at the planar joint 121 overflows under negative pressure and flows into the first inner cavity 3121, preventing the glue 130 at the planar joint 121 from flowing to the side walls of the outer shell 110 due to gravity and the curvature of the outer shell 110 of the product 100.

[0068] Furthermore, the second inner cavity 3131 of the second protrusion 313 is positioned relative to the side seams 122 on both sides of the product 100. As the inner core 321 slides upward along the first inner cavity 3121, the inner core 321 drives the sliding strips 3212 on both sides to slide upward along the second inner cavity 3131 of the second protrusion 313, resulting in a negative pressure state between the second inner cavity 3131 and the side seams 122, thereby accelerating the overflow of the adhesive 130 at the side seams 122. Since the first protrusion 312 abuts against the side seams 122 on both sides of the product 100, the adhesive 130 at the side seams 122 overflows under negative pressure and flows into the second inner cavity 3131, preventing the adhesive 130 from overflowing from the side seams 122.

[0069] Furthermore, after the negative pressure state ends, the sealing plate 320 and the inner core 321 are controlled to move downward along the first inner cavity 3121 by the lifting component 325, so that the sealing cavity 301 is in a positive pressure state, so that the glue 130 at the plane joint 121 and the side joint 122 can be quickly solidified.

[0070] It is worth mentioning that, please refer to Figure 12 This maintains a slight negative pressure state in the sealing cavity 301, the first cavity, and the second cavity for a period of time. The sealing plate 320 is then lowered, so that its bottom wall is completely pressed against the upper surface of the product 100. At this time, the sealing plate 320 moves the inner core 321 and the slide bar 3212 downwards together. The slide bar 3212 moves downwards along the second inner cavity 3131, pushing the adhesive 130 inside the second inner cavity 3131 downwards. Because the sealing cavity 301 is under slight positive pressure at this time, the adhesive 130 at the joint 120 solidifies quickly, and the slide bar 3212 pushes out excess adhesive 130 overflowing from the side joints 122 on both sides of the product 100, preventing excessive adhesive 130 from adhering to the side walls of the product 100.

[0071] The time during which the sealing cavity 301, the first cavity, and the second cavity are kept under a slight negative pressure is controlled according to the actual needs of the product 100. The time can be 10-30 minutes, i.e., 10 minutes, 15 minutes, 20 minutes, 25 minutes, and 30 minutes, etc.

[0072] In this embodiment, considering the practicality and reliability of the pressing fixture 010, the pressing fixture 010 needs to meet the requirements of intelligence. The intelligent features of the pressing fixture 010 are designed as follows: by setting a pressure sensor in the sealed cavity 301 of the pressing fixture 010, the pressure sensor and other hardware and software control and cooperation can realize the automatic pressure calibration of the pressing fixture 010 to complete the specific pressing of the specific product 100.

[0073] In this embodiment, considering that the pressing tool 010 may damage the handheld color ultrasound shell material during use, it is necessary to protect the contact surface where the pressing tool 010 contacts the shell 110. Cotton cloth padding is used to make the pressing device more practical and to avoid scratching or damaging the product 100.

[0074] This embodiment also proposes a pressing method for pressing tool 010, the pressing method including the following steps: S1: Place the glue-filled product 100 onto the pressing station 201; S2: The movable sealing structure 300 positions the product 100 within the sealing cavity 301; S3: Position product 100 so that the inner cavity corresponds to the seam position 120; S4: Operate the sealing structure 300 to adjust the sealing cavity 301 to a negative pressure state, so that the glue 130 in the joint position 120 flows into the inner cavity under negative pressure.

[0075] In this embodiment, S4 further includes the following steps: S41: Control the sealing plate 320 to move upward along the inner wall of the sealing box 310, so that the sealing cavity 301 is in a negative pressure state; S42: Move the sealing plate 320 upward. The sealing plate 320 drives the inner core 321 to move upward along the first inner cavity 3121, so that the inner cavity is in a negative pressure state, so that the glue 130 at the plane joint 121 flows into the first inner cavity 3121 and the second cavity under the negative pressure state. S43: Maintain negative pressure in the sealed cavity 301 for 10-30 minutes; S44: Move the sealing plate 320 down to make the sealing cavity 301 under positive pressure. The sealing plate 320 drives the inner core 321 to move downward along the first inner cavity 3121. The inner core 321 drives the two side slides 3212 to move downward along the second inner cavity 3131 respectively, pushing out the glue 130 in the second cavity and at the side seam 122.

[0076] In one alternative embodiment, this embodiment also proposes a method for manufacturing a handheld ultrasound diagnostic instrument. The handheld ultrasound diagnostic instrument includes a housing, which is spliced ​​together from at least two parts at the ultrasonic probe encapsulation point, and a seam position 120 is left on the outer surface of the housing.

[0077] Preparation methods include: S01: Place the glued shell onto the pressing station 201 of the pressing fixture 010; S02: The sealing structure 300 of the moving pressing tool 010 makes the housing located inside the sealing cavity 301; S03: Position product 100 so that the inner cavity corresponds to the seam position 120; S04: Operate the sealing structure 300 to adjust the sealing cavity 301 to a negative pressure state, so that the glue 130 in the joint position 120 flows into the inner cavity under negative pressure. S05: Maintain negative pressure within the sealed cavity 301; S06: Operate the sealing structure 300 to adjust the sealing cavity 301 to a positive pressure state so that the glue 130 at the joint position 120 can solidify faster. S07: Preparation complete, remove the shell.

[0078] S04 further includes the following steps: S041: control the sealing plate 320 to move upward along the inner wall of the sealing box 310, so that the sealing cavity 301 is in a negative pressure state; S042: Move the sealing plate 320 upward. The sealing plate 320 drives the inner core 321 to move upward along the first inner cavity 3121, so that the inner cavity is in a negative pressure state, so that the glue 130 at the plane joint 121 flows into the first inner cavity 3121 and the second cavity under the negative pressure state.

[0079] Regarding S05, the time for maintaining the negative pressure state within the sealed cavity 301 can be 10-30 minutes.

[0080] S06 further includes the following steps: S061: the sealing plate 320 is moved down, and the sealing plate 320 drives the inner core 321 to move down along the first inner cavity 3121, so that the sealing cavity 301 is in a positive pressure state, so that the glue 130 at the joint position 120 can be accelerated to solidify. S062: The inner core 321 drives the two side slides 3212 to move downward along the second inner cavity 3131 respectively, pushing out the glue 130 in the second cavity and at the side seam 122.

[0081] In summary, this embodiment of the invention provides a pressing fixture 010, which places the product 100 on the pressing station 201, with the sealing cavity 301 under positive pressure. The sealing structure 300 adjusts the pressure state of the sealing cavity 301 and the inner cavity to a negative pressure state, making the adhesive 130 at the joint position 120 have strong fluidity, which promotes the expulsion of air bubbles in the adhesive 130. At the same time, the adhesive 130 overflowing at the joint position 120 flows into the inner cavity under negative pressure, preventing the highly fluid adhesive 130 from flowing out along the joint position 120, and avoiding the problem of insufficient adhesive 130 on the upper surface of the product 100 due to volume reduction after solidification. This maintains the amount of adhesive 130 at the joint position 120 of the product 100, ensuring the overall shaping effect of the product 100.

[0082] Furthermore, the sealing structure 300 first adjusts the pressure state of the sealing cavity 301 and the inner cavity to a negative pressure state to improve the fluidity of the adhesive 130, while working with the inner cavity to prevent the adhesive 130 from flowing away; then the pressure state of the sealing cavity 301 and the inner cavity is adjusted to a positive pressure state, so that the adhesive 130 solidifies quickly, while the slide bar 3212 pushes out the excess adhesive 130 overflowing from the side joints 122 on both sides of the product 100, which can prevent too much adhesive 130 from adhering to the side walls of the product 100.

[0083] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
