Description

Technical Field

[0001] The invention relates to the technical field of underwater detection, and in particular to a manufacturing method and a manufacturing device of a Doppler underwater measuring device. Background Art

[0002] Sonar transducer, whether it is a transmitting transducer, a receiving transducer, or a transmitting and receiving transducer, is an important component of the Doppler underwater measuring device. After the sonar transducer is installed in the mounting groove of the shell body of the Doppler underwater measuring device, it needs to be vulcanized to form a sound-transmitting adhesive layer. The sound-transmitting adhesive layer is formed by vulcanizing and covering the surface of the sonar transducer with different types of adhesive such as epoxy resin or polyurethane according to the use and functional requirements of different products. It is a relatively important component of the Doppler underwater measuring device, which can directly affect the acoustic performance and product appearance quality of the Doppler underwater measuring device. At the same time, the sound-transmitting adhesive layer also plays the role of sealing the product in structure.

[0003] Specifically, factors such as the density, hardness, thickness and uniformity of the sound-transmitting adhesive layer, the presence or absence of bubbles in the transparent adhesive layer, the number and size of bubbles, and the color of the adhesive after vulcanization have a direct impact on the acoustic quality and appearance quality of the sound-transmitting adhesive layer formed after the adhesive is vulcanized. Therefore, when vulcanizing the adhesive, higher requirements are placed on the vulcanization process and equipment. In addition to primarily ensuring the quality of the sound-transmitting adhesive layer, the vulcanization process and operation process must also be simple, convenient and reliable, and have good production and economic benefits.

[0004] In the Doppler underwater measurement device, each of the four circular holes on the disc-shaped shell body is equipped with a set of independent sonar transducers. The four sets of sonar transducers share one shell body to form a transducer array, in which the basic structure of each independent sonar transducer is composed of a substrate, a backing and a piezoelectric ceramic. After the piezoelectric ceramic and the backing are assembled on the substrate to form a sonar transducer and the sonar transducer is installed in the installation groove of the shell body, it is necessary to vulcanize and cover the surface of the piezoelectric ceramic in each circular hole of the shell body with a layer of glue to a state flush with the outer surface of the shell body, forming a sound-permeable glue layer of a certain thickness, and at the same time sealing the product to prevent external water from entering the interior of the product.

[0005] For Doppler underwater measurement devices of this structural form, in the existing sound-transmitting adhesive layer vulcanization process method, there is no convenient, fast and efficient special vulcanization device or equipment to meet the vulcanization molding requirements, quality control requirements, and high efficiency and simplicity requirements of the sound-transmitting adhesive layer. In the existing process devices, when adjusting the horizontal angle of the upper surface of the shell body, temporary tooling such as adjustment wedges and fixed blocks are almost always used for adjustment. This temporary vulcanization process device needs to temporarily support and fix the shell body when vulcanizing the sound-transmitting adhesive layer corresponding to each sonar transducer. At the same time, the upper surface of the shell body where the circular hole is located is calibrated and adjusted with a level meter so that it needs to be kept level during the process of pouring the glue liquid, moving it to the oven, and curing in the oven. This vulcanization process method without special equipment has great limitations and unreliability, the quality is not easy to be guaranteed, and the operation time is relatively long. First, this simple process device relies on temporary tooling such as wedges and fixing blocks to support and fix. When adjusting the level of the upper surface of the shell body, it consumes more auxiliary time and has low efficiency. It is only suitable for a small number of temporary test pieces for research and development, and is not suitable for mass production of products. Second, when adjusting the horizontal angle of each upper surface on the shell body by using wedges and fixing blocks, it can only be roughly adjusted, and the horizontal accuracy of the adjustment is not high, which will affect the uneven thickness of the sound-permeable glue layer, thereby affecting the quality of the sound-permeable glue layer and the acoustic performance. Third, when relying on temporary tooling to support and fix the shell body, During the process of pouring glue, moving to the oven, and curing in the oven, the shell body is prone to slight sliding, resulting in instability of the adjusted level of the upper surface of the shell body, affecting the vulcanization quality of the sound-transmitting glue layer, requiring re-vulcanization and repair, and in severe cases even scrapping the sound-transmitting glue layer; fourthly, this simple process device can only carry out the vulcanization process for the next round hole after one of the round holes on the same shell body has been injected with glue and baked and cured, and it cannot achieve the goal of baking and curing all four round holes on the same shell body at the same time after the injection of glue, resulting in low production efficiency and not conducive to the production of mass products.

[0006] For example, in the invention patent application with the publication number CN116106576A, the inventor disclosed a manufacturing device for manufacturing a Doppler underwater measuring device, which includes a base unit, a bearing unit tiltedly arranged on the base unit, and a heat source arranged on the top of the bearing unit. The shell body of the Doppler underwater measuring device is carried by the bearing unit, and the heat source can apply glue between the shell body and the sonar transducer to solidify the glue to form a bonding portion (i.e., a sound-permeable glue layer). In this patent application, the base unit provides a front adjustment block and a rear adjustment block (i.e., a wedge block, a fixed block) to adjust the inclination angle of the bearing unit, thereby adjusting the inclination of the assembly surface of the shell body; after the glue is poured into one installation groove of the shell body, the glue needs to be heated and solidified before the glue can be poured into another installation groove of the shell body, and the glue pouring operation can be completed repeatedly for many times, which leads to low production efficiency of the Doppler underwater measuring device and is not conducive to the production of batch products.

[0007] In summary, for this type of Doppler underwater measurement device, there is still a lack of convenient, fast and efficient special devices and process methods to solve the above problems and requirements. Summary of the invention

[0046] Before describing in detail any embodiment of the present invention, it should be understood that the present invention is not limited in its application to the construction and arrangement details of the components described below or illustrated in the following figures.

In addition, "connect" and "couple" are not limited to physical or mechanical connections or connections.

[0047] Furthermore, on the first aspect, in the disclosure of the present invention, the orientations or positional relationships indicated by terms such as “longitudinal”, “transverse”, “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore the above terms cannot be understood as limitations on the present invention; on the second aspect, the term “one” should be understood as “at least one” or “one or more”, that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term “one” cannot be understood as a limitation on the quantity.

[0048] With reference to the accompanying drawings of the present invention Figures 1 to 22 The manufacturing process of a Doppler underwater measuring device 200 according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the manufacturing process of the Doppler underwater measuring device 200 is assisted by a manufacturing device 100.

[0049] Reference Figure 1 and Fig.14 The manufacturing device 100 includes a support unit 10, and the support unit 10 includes a support platform 11, a support ring 12 and two adjustable support legs 13. The bottom of each adjustable support leg 13 is respectively installed on the support platform 11, and the top of each adjustable support leg 13 is respectively rotatably installed on the support ring 12. In this way, each adjustable support leg 13 cooperates with each other to support the support ring 12 above the support platform 11, and by adjusting the length of each adjustable support leg 13, the inclination angle of the support ring 12 can be conveniently adjusted.

[0050] Specifically, each of the adjustable support legs 13 includes a bottom support leg 131, a top support leg 132 and an adjusting screw sleeve 133, wherein the bottom of the bottom support leg 131 is fixedly mounted on the support platform 11, for example, the bottom of the bottom support leg 131 can be locked to the support platform 11 by a screw, wherein the top of the top support leg 132 is rotatably mounted on the support ring 12, wherein the opposite ends of the adjusting screw sleeve 133 are respectively screwed on the top of the bottom support leg 131 and the bottom of the top support leg 132, so that each of the adjustable support legs 13 is used to support the support ring 12 above the support platform 11.

[0051] When the adjusting screw sleeve 133 is rotated in one direction, the adjusting screw sleeve 133 rotates relative to the top of the bottom support leg 131 and the bottom of the top support leg 132, so that the top of the bottom support leg 131 and the bottom of the top support leg 132 move away from each other and increase the length of the adjustable support leg 13. Correspondingly, when the adjusting screw sleeve 133 is rotated in the other direction, the adjusting screw sleeve 133 rotates relative to the top of the bottom support leg 131 and the bottom of the top support leg 132, so that the top of the bottom support leg 131 and the bottom of the top support leg 132 move closer to each other and shorten the length of the adjustable support leg 13, so that the inclination angle of the support ring 12 can be adjusted.

[0052] That is to say, the length of the adjustable support leg 13 can be adjusted by rotating the adjusting screw sleeve 133 clockwise and counterclockwise, which makes the adjustment of the inclination angle of the support ring 12 convenient and quick, and the auxiliary time consumed is short.

[0053] Continue to refer to the attached Figure 1 and Fig.14 , the support unit 10 further includes a plurality of support feet 14, each of which is screwed to the bottom of the support platform 11 at intervals, and is used to adjust and maintain the support platform 11 in a horizontal state. The specific process may be, first, placing the support unit 10 on the workbench in a manner that each of the support feet 14 contacts the workbench, and secondly, placing a universal level 300 on the upper surface of the support platform 11, observing the level bubble of the universal level 300, and if the level bubble is not in the exact center of the cross scale, rotating the support feet 14 at the corresponding position to adjust the level of the support platform 11 until the level bubble of the universal level 300 is in the exact center of the cross scale. It can be understood that when the level bubble of the universal level 300 is in the exact center of the cross scale, the support platform 11 is in a horizontal state.

[0054] Preferably, the support platform 11 is rectangular, and a support foot 14 is respectively disposed at the four corners of the support platform 11 .

[0055] Reference Figure 2 , Figures 15 to 17The manufacturing device 100 includes a positioning gland 20, and the positioning gland 20 has a gland cavity 21 and a plurality of gland channels 22 connected to the gland cavity 21. The shape and size of the gland cavity 21 of the positioning gland 20 are consistent with the shape and size of a shell body 210 of the Doppler underwater measurement device 200, so that the shell body 210 can be accommodated in the gland cavity 21 of the positioning gland 20 in a manner that the peripheral wall of the shell body 210 and the inner wall of the positioning gland 20 used to form the gland cavity 21 are in contact with each other. In this way, during the vulcanization operation, the shell body 210 and the positioning gland 20 will not be misaligned with each other, wherein each of the positioning gland 20 The central axis of the gland channel 22 coincides with the central axis of each mounting groove 211 of the shell body 210, and the inner diameter of the gland channel 22 of the positioning gland 20 is larger than the inner diameter of the mounting groove 211 of the shell body 210, so that a portion of the assembly surface 212 of the shell body 210 is exposed to the gland channel 22 of the positioning gland 20, and the portion of the assembly surface 212 of the shell body 210 exposed to the gland channel 22 of the positioning gland 20 is annular. In a specific example of the present invention, the number of the mounting grooves 211 of the shell body 210 is four, and accordingly, the number of the gland channels 22 of the positioning gland 20 is also four.

[0056] It can be understood that the Doppler underwater measuring device 200 includes a plurality of transducers 220, each of which is composed of a backing 221 and a piezoelectric ceramic 222, the piezoelectric ceramic 222 being stacked on top of the backing 221, the transducer 220 being installed in the mounting groove 211 of the shell body 210, and the upper surface of the piezoelectric ceramic 222 of the transducer 220 is lower than the assembly surface 212 of the shell body 210.

[0057] In order to ensure that the shell body 210 is reliably installed in the gland cavity 21 of the positioning gland 20, in the present invention, the peripheral wall of the positioning gland 20 is provided with at least two notches 23. After the shell body 210 is installed in the gland cavity 21 of the positioning gland 20, each of the notches 23 of the positioning gland 20 corresponds to the peripheral wall of the shell body 210, wherein the manufacturing device 100 further includes a clamp 30, and the clamp 30 is mounted on the portion of the positioning gland 20 where the notches 23 are provided. In this way, the clamp 30 can slightly deform the portion of the positioning gland 20 where the notches 23 are provided, so as to generate a larger friction force between the inner wall of the positioning gland 20 and the peripheral wall of the shell body 210, thereby reliably installing the shell body 210 in the gland cavity 21 of the positioning gland 20.

[0058] Continue to refer to the attached Figure 2 , Figures 15 to 17 The positioning gland 20 has a plurality of reference planes 24, and the openings of the respective gland channels 22 are respectively formed in the middle of the respective reference planes 24. After the shell body 210 is installed in the gland cavity 21 of the positioning gland 20, the respective assembly surfaces 212 of the shell body 210 are respectively parallel to the respective reference planes 24 of the positioning gland 20. In this way, it can be judged whether the assembly surface 212 of the shell body 210 is in a horizontal state in the subsequent process by judging whether the reference plane 24 of the positioning gland 20 is in a horizontal state. It can be understood that since the shape and size of the pressure cover cavity 21 of the positioning pressure cover 20 are consistent with the shape and size of the outer surface of the shell body 210, after the shell body 210 is installed in the pressure cover cavity 21 of the positioning pressure cover 20, as long as the outer surface of the shell body 210 and the inner surface of the positioning pressure cover 20 used to form the pressure cover cavity 21 are completely fitted, it can be ensured that the various assembly surfaces 212 of the shell body 210 are respectively parallel to the various reference planes 24 of the positioning pressure cover 20.

[0059] Reference Figure 3 and Fig.18 , install the assembly formed by the shell body 210 and the positioning cover 20 on the support ring 12, and make one of the reference planes 24 of the positioning cover 20 face upwards, then place the universal level 300 on the reference plane 24 of the positioning cover 20, adjust the length of each adjustable support leg 13 by rotating the adjusting screw sleeve 133 of each adjustable support leg 13 clockwise or counterclockwise, observe the level bubble of the universal level 300, when the level bubble is in the center of the cross scale, it means that the reference plane 24 of the positioning cover 20 is in a horizontal state, and at this time, the assembly surface 212 of the shell body 210 corresponding to the reference plane 24 of the positioning cover 20 is also in a horizontal state, in this way, the manufacturing device 100 can easily adjust the horizontality of the assembly surface 212 of the shell body 210 and ensure accuracy.

[0060] It can be understood that after the assembly formed by the shell body 210 and the positioning cover 20 is installed on the support ring 12, in order to avoid misalignment of the assembly and the support ring 12, the inner diameter size of the installation cavity 213 of the shell body 210 is consistent with the outer diameter size of the support ring 12, so that the assembly is installed on the support ring 12 in a way that the support ring 12 extends into the installation cavity 213 of the shell body 210, and the outer wall of the support ring 12 is fitted to the inner wall of the shell body 210 for forming the installation cavity 213.

[0061] Reference Figure 4 and Fig.19 , the glue liquid is placed in a vacuum barrel for bubble elimination treatment, and then the glue liquid is poured into the mounting groove 211 of the shell body 210 through the gland channel 22 of the positioning gland 20, and the liquid level of the glue liquid is slightly higher than the assembly surface 212 of the shell body 210. At this time, the glue liquid fills the mounting groove 211 of the shell body 210 and covers the backing 221 and the piezoelectric ceramic 222. For example, in a specific example of the present invention, the liquid level of the glue liquid can be about 0.1mm-0.2mm higher than the assembly surface 212 of the shell body 210. In the present invention, by making the liquid level of the glue liquid slightly higher than the assembly surface 212 of the shell body 210, it can not only ensure that the glue liquid fills the mounting groove 211 of the shell body 210, but also ensure the consistency of the glue liquid subsequently retained in the mounting groove 211 of the shell body 210.

[0062] In other words, during the glue pouring process, even if the amount of glue poured into each of the mounting grooves 211 of the shell body 210 is slightly different, by allowing the liquid level of the glue to be higher than the assembly surface 212 of the shell body 210, the consistency of the glue subsequently retained in the mounting grooves 211 of the shell body 210 can be ensured, which is crucial for ensuring the acoustic performance and appearance of the Doppler underwater measurement device 200.

[0063] Reference Figure 5 and Fig. 20The manufacturing device 100 further includes a plurality of glue layer flattening covers 40, each of which has a glue overflow hole 41. The glue layer flattening covers 40 are installed in the pressure cover channel 22 of the positioning pressure cover 20, and the glue layer flattening covers 40 are pressed tightly against the assembly surface 212 of the shell body 210. In this process, excess glue overflows through the glue overflow hole 41 of the glue layer flattening cover 40. At this time, the glue layer flattening cover 40 can ensure that the liquid level of the glue held in the installation groove 211 of the shell body 210 is flush with the assembly surface 212 of the shell body 210. It should be noted that, since the portion of the assembly surface 212 of the shell body 210 exposed to the pressure cover channel 22 of the positioning pressure cover 20 is annular, when the glue layer flattening cover 40 is pressed against the assembly surface 212 of the shell body 210, it can be ensured that the liquid level of the glue liquid maintained in the installation groove 211 of the shell body 210 is a plane and flush with the assembly surface 212 of the shell body 210.

[0064] Preferably, the outer diameter of the glue layer flattening cover 40 is consistent with the inner diameter of the pressing channel 22 of the positioning pressing cover 20. In this way, in the process of installing the glue layer flattening cover 40 on the positioning pressing cover 20, the peripheral wall of the glue layer flattening cover 40 and the inner wall of the positioning pressing cover 20 for forming the pressing channel 22 fit together, so that excess glue will only overflow from the glue overflow hole 41 of the glue layer flattening cover 40, and will not overflow from between the positioning pressing cover 20 and the glue layer flattening cover 40, so as to facilitate the cleaning of the overflowed glue.

[0065] Reference Figure 6 and Fig.21 The manufacturing device 100 further includes a plurality of glue overflow hole plugs 50, which are inserted into the glue overflow holes 41 of the glue layer flattening cover 40, and ensure that the bottom surface of the glue overflow hole plugs 50 is flush with the bottom surface of the glue layer flattening cover 40, so that it can be ensured that the liquid level of the glue liquid maintained in the mounting groove 211 of the shell body 210 is a complete plane.

[0066] Reference Figure 7In the process of inserting the overflow hole plug 50 into the overflow hole 41 of the glue layer flattening cover 40, in order to ensure that the liquid level of the glue liquid maintained in the mounting groove 211 of the shell body 210 is a complete plane, the overflow hole 41 of the glue layer flattening cover 40 has an upper hole 411 and a lower hole 412 connected to the upper hole 411, the inner diameter of the upper hole 411 is larger than the inner diameter of the lower hole 412, the overflow hole plug 50 has a lap section 51 and a plug section 52 extending downward from the lap section 51, the height dimension of the lap section 51 is consistent with the depth dimension of the upper hole 411, and the outer diameter dimension of the lap section 51 is slightly smaller than the inner diameter dimension of the upper hole 411, and the height dimension of the plug section 52 is consistent with the depth dimension of the lower hole 412, And the outer diameter of the plugging section 52 is slightly smaller than the inner diameter of the lower hole 412. In the process of inserting the overflow hole plugging section 50 into the overflow hole 41 of the glue layer flattening cover 40, the glue in the overflow hole 41 of the glue layer flattening cover 40 can be squeezed out by the overflow hole plugging section 50, and after the overflow hole plugging section 50 is inserted into the overflow hole 41 of the glue layer flattening cover 40, the overlapping section 51 overlaps with the step position formed by the upper hole 411 and the lower hole 412 of the glue layer flattening cover 40, and the upper surface of the overlapping section 51 is flush with the upper surface of the glue layer flattening cover 40, the lower surface of the plugging section 52 is flush with the lower surface of the glue layer flattening cover 40, and the peripheral wall of the plugging section 52 is in contact with the inner wall of the glue layer flattening cover 40 for forming the lower hole 412.

[0067] Reference Figure 7 and Fig. 22 The manufacturing device 100 further includes a plurality of set screw plugs 60, which can be screwed together with the positioning gland 20, so that the set screw plugs 60 can be screwed into the gland channel 22 of the positioning gland 20, and the set screw plugs 60 screwed into the gland channel 22 of the positioning gland 20 can tighten the glue layer flattening cover 40 and the overflow hole plug 50. Specifically, the set screw plug 60 has an external thread structure, and the top of the positioning gland 20 for forming the gland channel 22 is provided with an internal thread structure, and the external thread structure of the set screw plug 60 and the internal thread structure of the positioning gland 20 cooperate with each other, so that the set screw plug 60 and the positioning gland 20 can be screwed together.

[0068] After the set screw 60 is screwed into the positioning gland 20, the glue filling operation of the installation groove 211 of the shell body 210 can be completed. Then, the glue filling operation of the remaining installation grooves 211 of the shell body 210 can be performed in the same way. Figure 7 and Figure 8 .

[0069] Next, refer to the attached Fig.11 , the support unit 10 is smoothly moved into an oven 400, and the shell body 210 is vulcanized so that the glue poured into the mounting grooves 211 of the shell body 210 is solidified to form a bonding portion 230 of the Doppler underwater measurement device 200. It can be understood that since the set screw 60 is screwed into the positioning gland 20, the set screw 60 can reliably press the glue layer flattening cover 40 onto the assembly surface 212 of the shell body 210. During the vulcanization process, even if the assembly surface 212 of the shell body 210 is in an inclined state, the glue poured into the mounting grooves 211 of the shell body 210 will not flow, so that the surface of the bonding portion 230 formed after the vulcanization is flush with the assembly surface 212 of the shell body 210.

[0070] Reference Fig.12 and Fig.13 After vulcanization, the shell body 210 is removed from the support ring 12 and the positioning gland 20, and a circuit board 240 of the Doppler underwater measuring device 200 is installed in the installation cavity 213 of the shell body 210 and the bottom cover 250 is installed in the shell body 210 to obtain the Doppler underwater measuring device 200. It can be understood that the transducer 220 is connected to the circuit board 240.

[0071] It should be noted that, since the outer diameter of the plugging section 52 of the overflow hole plug 50 is slightly smaller than the inner diameter of the lower hole 412 of the glue layer flattening cover 40, after the overflow hole plug 50 is inserted into the overflow hole 41 of the glue layer flattening cover 40, there is a gap between the plugging section 52 of the overflow hole plug 50 and the glue layer flattening cover 40. After vulcanization, the gluing part 230 may produce "flash" at the position corresponding to the gap. Since the size of the gap can be very small, the thickness of the "flash" is relatively small. When the shell body 210 is disassembled from the manufacturing device 100, the "flash" will be torn off by the positioning pressure cover 20 and the overflow hole plug 50, and will not affect the appearance and acoustic performance of the gluing part 230.

[0072] According to another aspect of the present invention, the present invention provides a method for manufacturing the Doppler underwater measurement device 200, wherein the manufacturing method comprises the following steps: S1, installing the shell body 210 of the Doppler underwater measurement device 200 on the positioning gland 20 of the manufacturing device 100, wherein each of the mounting grooves 211 of the shell body 210 corresponds to each of the gland channels 22 of the positioning gland 20; S2, installing the assembly formed by the shell body 210 and the positioning gland 20 on the support ring 12 of the manufacturing device 100; S3, after adjusting the assembly surface 212 of the shell body 210 corresponding to the mounting groove 211 to be filled with glue to a horizontal state, filling glue into the mounting groove 211 of the shell body 210 through the gland channel 22 of the positioning gland 20; S4, allowing the glue layer flattening cover 40 of the manufacturing device 100 to flatten the glue poured into the mounting groove 211 of the shell body 210, wherein the liquid surface of the glue is flush with the assembly surface 212 of the shell body 210; S5, after all the installation grooves 211 of the shell body 210 are filled with glue, the glue is dried to form the glued portion 230; S6, after the shell body 210 is disassembled from the manufacturing device 100, the circuit board 240 and the bottom cover 250 are sequentially installed on the shell body 210 to manufacture the Doppler underwater measurement device 200.

[0073] Compared with the prior art, the manufacturing method of the present invention can reduce the baking and curing time by 3 / 4 by allowing all the installation grooves 211 of the shell body 210 to be baked and cured after being filled with glue for vulcanization operation, thereby greatly shortening the production cycle and meeting the needs of mass product vulcanization.

[0074] The glue liquid poured into all the installation grooves 211 of the shell body 210 is always flattened by the glue layer flattening cover 40. During the baking and curing process, even if the assembly surface 212 of the shell body 210 is in an inclined state, the glue liquid poured into the installation grooves 211 of the shell body 210 will not flow. This enables the manufacturing method of the present invention to complete the baking and curing of the glue liquid poured into the installation grooves 211 at different positions of the shell body 210 at one time, and the surface of the bonding part 230 obtained after baking and curing is flush with the assembly surface 212 of the shell body 210, thereby satisfying and improving the vulcanization quality of the bonding part 230 and ensuring the acoustic performance of the Doppler underwater measurement device 200.

[0075] In the step S5, the manufacturing method of the present invention allows the manufacturing device 100 to be smoothly moved into the oven 400 to perform the vulcanization operation on the shell body 210, and the shell body 210 is removed from the manufacturing device 100 only after the vulcanization is completed. That is, during the entire vulcanization operation, the shell body 210 is always stably supported by the manufacturing device 100. This method is conducive to ensuring the quality of vulcanization and avoiding unnecessary rework.

[0076] In the step S1, the shell body 210 is installed on the positioning cover 20 through the clamp 30. In this way, the manufacturing method can ensure that the shell body 210 is reliably installed on the positioning cover 20, so that the various assembly surfaces 212 of the shell body 210 and the various reference planes 24 of the positioning cover 20 remain parallel. In this way, subsequently, by judging whether the reference plane 24 of the positioning cover 20 is in a horizontal state, it can be judged whether the assembly surface 212 of the shell body 210 is in a horizontal state, which is beneficial to the subsequent glue filling operation. It can be understood that since the shape and size of the pressure cover cavity 21 of the positioning pressure cover 20 are consistent with the shape and size of the shell body 210, after the shell body 210 is installed in the pressure cover cavity 21 of the positioning pressure cover 20, as long as the outer surface of the shell body 210 and the inner surface of the positioning pressure cover 20 used to form the pressure cover cavity 21 are completely in contact with each other, it can be ensured that the various assembly surfaces 212 of the shell body 210 are respectively parallel to the various reference planes 24 of the positioning pressure cover 20, and misalignment of the shell body 210 and the positioning pressure cover 20 can be avoided. Preferably, the clamp 30 is mounted on the portion of the positioning cover 20 where the notch 23 is provided, so that the clamp 30 can slightly deform the portion of the positioning cover 20 where the notch 23 is provided, so as to generate a larger friction force between the inner wall of the positioning cover 20 and the peripheral wall of the shell body 210, thereby reliably installing the shell body 210 in the cover cavity 21 of the positioning cover 20.

[0077] In the step S3, the specific steps of adjusting the assembly surface 212 of the shell body 210 corresponding to the installation groove 211 that needs to be glued to a horizontal state include: first, placing the gimbal level 300 on the reference plane 24 of the positioning cover 20, and observing whether the level bubble of the gimbal level 300 is in the center of the cross scale; secondly, in the process of adjusting the length of at least one of the adjustable support legs 13, continuously observe whether the level bubble of the gimbal level 300 is in the center of the cross scale, and after observing that the level bubble of the gimbal level 300 is in the center of the cross scale, stop adjusting the length of each adjustable support leg 13. At this time, the reference plane 24 of the positioning cover 20 is in a horizontal state, and accordingly, the assembly surface 212 of the shell body 210 corresponding to the reference plane 24 of the positioning cover 20 is also in a horizontal state.

[0078] In the manufacturing method of the present invention, the assembly surface 212 of the shell body 210 can be adjusted to a horizontal state by adjusting the length of the adjustable support leg 13, and the length adjustment method of the adjustable support leg 13 is achieved by rotating the adjusting screw sleeve 133 of the adjustable support leg 13 clockwise and counterclockwise, that is, the opposite ends of the adjusting screw sleeve 133 are respectively screwed on the top of the bottom support leg 131 and the bottom of the top support leg 132. In this way, not only can the length of the adjustable support leg 13 be conveniently adjusted, but also after the length of the adjustable support leg 13 is adjusted, the adjustable support leg 13 can be self-locking, so that the length of the adjustable support leg 13 remains unchanged in the subsequent glue filling operation or baking and curing operation.

[0079] In a specific example of the manufacturing method of the present invention, the step S4 further includes the steps of: S4.1, pressing the glue layer flattening cover 40 against the assembly surface 212 of the shell body 210, S4.2, screwing the locking screw 60 of the manufacturing device 100 into the pressure cover channel 22 of the positioning pressure cover 20, and allowing the locking screw 60 to press the glue layer flattening cover 40. In this way, in the subsequent process of glue filling operation on other mounting grooves 211 of the shell body 210 and baking and curing the glue liquid poured into these mounting grooves 211 of the shell body 210, the manufacturing method can ensure that the glue layer flattening cover 40 is always in a state of flattening the glue poured into the mounting grooves 211 of the shell body 210, thereby ensuring that the surface of the obtained gluing part 230 is flush with the assembly surface 212 of the shell body 210. Optionally, in other specific examples of the manufacturing method of the present invention, the adhesive layer flattening cover 40 can also be directly screwed onto the positioning pressure cover 20. Specifically, the adhesive layer flattening cover 40 has an external thread structure, and the top of the positioning pressure cover 20 for forming the pressure cover channel 22 is provided with an internal thread structure. The external thread structure of the adhesive layer flattening cover 40 and the internal thread structure of the positioning pressure cover 20 cooperate with each other, so that the adhesive layer flattening cover 40 and the positioning pressure cover 20 can be screwed together, so as to directly screw the adhesive layer flattening cover 40 onto the positioning pressure cover 20.

[0080] In order to ensure that the glue fills the installation groove 211 of the shell body 210 and ensure the consistency of the glue subsequently maintained in the installation groove 211 of the shell body 210, in the step S3, the liquid level of the glue poured into the installation groove 211 of the shell body 210 is slightly higher than the assembly surface 212 of the shell body 210 by about 0.1mm-0.2mm, and in the step S4.1, excess glue is allowed to overflow through the overflow hole 41 of the glue layer flattening cover 40.

[0081] Since the glue layer flattening cover 40 is provided with the glue overflow hole 41 for overflowing the excess glue liquid filled in the mounting groove 211 of the shell body 210, after the glue layer flattening cover 40 is pressed against the assembly surface 212 of the shell body 210, the glue overflow hole plug 50 is required to plug the glue overflow hole 41 of the glue layer flattening cover 40. That is, after the step S4.1 and before the step S4.2, the step S4 further includes the step of plugging the glue overflow hole plug 50 into the glue overflow hole 41 of the glue layer flattening cover 40, and in the step S4.2, allowing the set screw 60 to press against the glue overflow hole plug 50 to prevent the glue overflow hole plug 50 from falling off from the glue overflow hole 41 of the glue layer flattening cover 40.

The purpose of the present invention has been fully and effectively achieved.
