Description

Technical Field

[0001] This utility model relates to the field of assembly fixture technology, and in particular to an integrated assembly and pressure-holding fixture. Background Technology

[0002] The optical window, a key component of LiDAR (Light Detection and Ranging) systems, plays a crucial role. The assembly technology of the optical window directly affects the optical performance, environmental adaptability, system reliability, and lifespan of the LiDAR system. The assembly process for the LiDAR optical window mainly involves bonding and welding. For bonding, the current common practice is to place the pre-applied adhesive housing onto a dedicated assembly fixture for assembly. After assembly, it is transferred to a dedicated pressure-holding and baking fixture for pressure holding, and finally, the pressure-holding and baking fixture is transferred to an oven for baking and curing. During this process, if the adhesive has not yet cured when the assembled optical window and housing are transferred to the pressure-holding and baking fixture, improper operation by the operator may cause the optical window to shift or even fall off. Furthermore, because existing pressure-holding and baking fixtures use a rigid connection, errors in the conformation of the fixture's pressure blocks or insufficient guidance from the fixture's extension and retraction may lead to uneven stress on the optical window, causing it to shift or misalign during the pressure holding process. Meanwhile, the pressure-holding block in the fixture is usually a complete copy of the light window, so the light window may crack due to thermal expansion and contraction during the baking process. Utility Model Content

[0003] This utility model provides an integrated assembly and pressure-holding fixture to solve at least one of the problems that may occur during the pressure-holding and baking of products in the prior art, such as component displacement and cracking.

[0004] According to one aspect of the present invention, an integrated assembly and pressure-holding fixture is provided, comprising a first mold and a second mold. The first mold is provided with a first mounting structure for mounting a first part of a product to be assembled, and the second mold is provided with a second mounting structure for mounting a second part of a product to be assembled. A first detachable connection structure is provided between the first mold and the second mold.

[0005] This utility model's integrated assembly and pressure-holding fixture features a first mounting structure on a first mold and a second mounting structure on a second mold. This allows for the fixation of the first and second parts of the product, ensuring precise assembly of the first and second parts after assembly. Simultaneously, a first detachable connection structure is provided on both molds to maintain pressure after assembly, thus providing pressure holding for the assembled product. The assembled molds can then be transferred to a baking fixture, completing the entire product assembly process. This utility model integrates product assembly and pressure holding, effectively preventing component displacement issues that may occur during transfer to the pressure-holding and baking fixture. This integrated assembly and pressure-holding fixture can be used not only for assembling the optical window and housing of a LiDAR system but also for other products requiring assembly and pressure holding, ensuring product assembly quality.

[0006] In some embodiments, the first mounting structure includes a first vacuum adsorption structure disposed on the first mold, the first vacuum adsorption structure including a first adsorption hole and a first air extraction hole that are interconnected, the first adsorption hole being disposed on one side of the first mold for mounting a first part of the product to be assembled.

[0007] Therefore, by setting it up in this way, the first part of the product can be adsorbed and fixed using the first vacuum adsorption structure.

[0008] In some embodiments, the first mounting structure includes a contour-following pressure-holding structure disposed on one side of the first mold for mounting a first part of the product to be assembled, the contour-following pressure-holding structure including a plurality of support columns, the top surface of the support columns being configured as a contour-following surface corresponding to the shape of the first part of the product to be assembled. The first adsorption hole is disposed on the contoured surface of the support column.

[0009] Therefore, this setup allows for the uniform application of holding pressure to the first part of the product using dispersed support columns. Compared to the fully contoured structure in existing technologies, this effectively avoids the problem of cracking of the light window due to thermal expansion and contraction during baking, thus improving production yield. At the same time, the combination of the support columns and the first vacuum adsorption structure ensures the adsorption performance of the first part of the product. During adsorption, the support columns with contoured surfaces can automatically adjust the position of the first part of the product to ensure the accuracy of the assembly between the first and second parts of the product after the first and second molds are assembled, thereby ensuring the assembly quality of the product.

[0010] In some embodiments, the first mold includes a first template and a second template. A first surface of the first template is used to mount a first part of the product to be assembled. The second template is disposed on a surface of the first template opposite to the first surface. An elastic structure is provided between the second template and the first template. The first detachable connection structure is disposed between the second template and the second mold. The first vacuum adsorption structure is disposed on the first template; The second template is provided with a third vacuum adsorption structure, which includes a third adsorption hole and a third air extraction hole that are interconnected, and the third adsorption hole is connected to the first air extraction hole.

[0011] Therefore, with this configuration, after the first mold and the second mold are assembled, the first template in the first mold, under the pressure of the second template and the elastic structure, will continuously exert a preset assembly pressure on the first and second parts of the product, thus maintaining pressure on the product. Simultaneously, because an elastic structure is provided between the first and second templates, allowing relative movement between them, the first vacuum adsorption structure and the third vacuum adsorption structure can be connected via a pipe.

[0012] In some embodiments, a positioning structure is provided on one side of the first mold for mounting the first part of the product to be assembled, the positioning structure being used to assist the first mold in being accurately mounted onto the second mold.

[0013] Therefore, by using this configuration, the positioning structure can be used to ensure the accuracy of the assembly between the first mold and the second mold, thereby improving the assembly accuracy between the first and second parts of the product and ensuring the assembly quality of the product.

[0014] In some embodiments, a base is also included, on which a driving assembly is provided. The driving assembly is provided with a movable end that is driven to move. The first mold is detachably disposed on the movable end, such that the first mold is assembled onto the second mold through the first detachable connection structure under the drive of the driving assembly. A second detachable connection structure is provided between the second mold and the base.

[0015] Therefore, this configuration allows for control of the movement of the first mold using the base and the drive assembly mounted on it, ensuring pressure between the first and second molds during assembly and guaranteeing assembly quality. Simultaneously, the first mold is detachably mounted on the movable end of the drive assembly, and the second mold is detachably mounted on the base, allowing the first and second molds to be completely removed from the base after assembly and directly transferred for baking. This effectively avoids potential component displacement issues during the transfer of the assembled product to the pressure-holding baking fixture.

[0016] In some embodiments, the movable end is provided with a connecting plate structure, and the first mold is detachably mounted on the connecting plate structure; The connecting plate structure is provided with a second vacuum adsorption structure, which includes a second adsorption hole and a second air extraction hole that are interconnected. When the first mold is installed on the connecting plate structure, the second adsorption hole is connected to the third air extraction hole.

[0017] Therefore, this configuration allows the second vacuum adsorption structure on the connecting plate structure to be combined with the first vacuum adsorption structure on the first mold, enabling the vacuum-drawing mechanism to be mounted on the base instead of on the first mold. Thus, once the first and second molds are assembled, simply detaching the first mold from the connecting plate structure allows for the complete transfer of the assembled first and second molds without needing to separately remove the vacuum-drawing mechanism from the first mold, making the operation more convenient and faster.

[0018] In some embodiments, the first mold and the connecting plate structure are detachably connected by a magnetic attraction structure.

[0019] Therefore, this design makes it easier to install or remove the first mold from the connecting plate structure. Simultaneously, the magnetic structure has a certain self-positioning capability, ensuring that the first and second vacuum adsorption structures align after the first mold is installed on the connecting plate structure, thus ensuring the proper functioning of the first mounting structure.

[0020] In some embodiments, the connecting plate structure includes a first mounting plate and a second mounting plate. The first mounting plate is disposed on the movable end, and the second mounting plate is mounted on the first mounting plate by equal-height screws. A gap is left between the equal-height screws and the first mounting plate in the axial direction and between the equal-height screws and the first mounting plate in the circumferential direction. The first mold is detachably mounted on the second mounting plate.

[0021] Therefore, by using this configuration, the installation gap between the second mounting plate and the first mounting plate can be utilized so that when the drive component controls the movement of the first mold, the second mounting plate can adaptively adjust its position according to the assembly position between the first mold and the second mold, thereby ensuring the assembly accuracy between the first mold and the second mold.

[0022] In some embodiments, the base is provided with a sliding bottom plate; The second detachable connection structure includes a locking block structure disposed on the second mold, a limiting structure disposed on the base that matches the locking block structure, and a rotating plunger that penetrates the locking block structure to abut against the base plate. When the base plate slides to the first limit position, the position of the second mold corresponds to the position of the first mold.

[0023] Therefore, by setting it up in this way, the second mold can be fixed and installed on the base using the limiting structure, ensuring the stability of the installation position of the second mold, ensuring the accuracy of the assembly between the first mold and the second mold, and further ensuring the stability of the installation position of the second mold; At the same time, it allows the second mold to be moved away from the upper drive components and other structures when it needs to be disassembled, thereby improving the convenience of disassembling the second mold.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Figure 1 The diagram schematically illustrates the structural composition of an integrated pressure-holding fixture according to one embodiment of this utility model. (Refer to...) Figure 1 As shown, the assembly and pressure-holding integrated fixture of this utility model includes a first mold 1 and a second mold 2. The first mold 1 is provided with a first mounting structure for mounting a first part of the product to be assembled, the second mold 2 is provided with a second mounting structure for mounting a second part of the product to be assembled, and a first detachable connection structure 31 is provided between the first mold 1 and the second mold 2.

[0034] The first mold 1 and the second mold 2 can be configured as an assembly connection relationship of vertical assembly, horizontal assembly, or other common assembly relationships. This utility model does not limit the specific assembly relationship in this regard.

[0035] In some possible implementations, the first mounting structure provided on the first mold 1 can be configured as a first vacuum adsorption structure. The vacuum adsorption structure can adsorb the first part of the product to be assembled onto the first mold 1, thereby ensuring that regardless of the assembly relationship between the first mold 1 and the second mold 2, the first part of the product to be assembled can be stably mounted on the first mold 1. This ensures that when the first mold 1 and the second mold 2 are assembled, the first and second parts of the product to be assembled can be precisely assembled, thus ensuring assembly quality.

[0036] The first vacuum adsorption structure may include a first adsorption hole 411 and a first suction hole 412 that are interconnected. The first adsorption hole 411 is disposed on one side of the first mold 1 for mounting the first part of the product to be assembled, while the first suction hole 412 may be disposed on other sides of the first mold 1 to facilitate connection with an external vacuuming mechanism without affecting the installation of the product to be assembled.

[0037] In other possible embodiments, the first mounting structure may include a contour-following pressure-holding structure on one side of the first mold 1 for mounting the first part of the product to be assembled. This contour-following pressure-holding structure includes a plurality of support pillars 413, and the top surfaces of these support pillars 413 are all configured as contoured surfaces corresponding to the shape of the first part of the product, thereby enabling the uniform application of pressure to the first part of the product using these contoured surfaces. Compared with the fully contoured structure in the prior art, this method effectively avoids the problem of light window cracking due to thermal expansion and contraction during baking, thus improving production yield.

[0038] Specifically, the number of support columns 413 can be designed according to the actual situation. It is only necessary to reserve a certain interval between each support column 413 to avoid the support columns 413 from forming a completely shaped structure. The structure of the support column 413 can be a square column structure or a cylindrical main structure. This utility model does not limit this.

[0039] It is understood that the first mounting structure in the above two embodiments can be separately mounted on the first mold 1, or it can be combined with another structure on the first mold 1. Specifically, refer to... Figure 2 As shown, the first mold 1 is provided with several support columns 413, and the top surface of each support column 413 is a contoured surface. The first air extraction hole 412 of the first vacuum adsorption structure is located on the side of the first mold 1, and the first adsorption hole 411 is located in the middle of the contoured surface, so as to better adsorb the first part of the product to be assembled.

[0040] In other possible embodiments, the first mold 1 may include a first template 11 and a second template 12. The first surface of the first template 11 is used to mount the first part of the product to be assembled, and the second template 12 is disposed on the surface of the first template 11 opposite to the first surface. An elastic structure is provided between the second template 12 and the first template 11. In this case, the first detachable connection structure 31 between the first mold 1 and the second mold 2 is disposed between the second template 12 and the second mold 2. This arrangement utilizes the pressure of the elastic structure as a pre-set assembly pressure, achieving pressure retention for the product after the first mold 1 and the second mold 2 are assembled together. Specifically, the elastic structure can be a spring, a sheet spring, or other commonly used structures with elastic deformation properties; this invention does not limit this.

[0041] Reference Figure 2As shown, the first mold 1 consists of a first template 11 and a second template 12. In this embodiment, the first template 11 and the second template 12 have the same shape and are stacked. The first surface of the first template 11 is used to mount the first part of the product to be assembled, and the second template 12 is disposed on the surface of the first template 11 opposite to the first surface. The elastic structure specifically includes a spring disposed between the first template 11 and the second template 12. The elastic structure also includes a limiting guide post 131 and a limiting pad 132. The limiting guide post 131 is connected and fixed to the first template 11 and extends through the second template 12. A limiting baffle is provided at the end of the limiting guide post 131 away from the first template 11. The limiting pad 132 is slidably disposed outside the limiting guide post 131, with one end abutting against the second template 12 and the other end abutting against the limiting baffle. The limiting pad 132 can be made of a material with elastic cushioning properties, such as rubber. When the spring between the first template 11 and the second template 12 is in its normal state, the second template 12 and the limiting baffle will clamp the limiting pad 132 to prevent the second template 12 from detaching from the first template 11. When the spring between the first template 11 and the second template 12 is in a compressed state, the limiting pad 132 will move closer to the first template 11 along with the second template 12, thus moving the limiting pad 132 away from the limiting baffle.

[0042] In this embodiment, both the aforementioned first vacuum adsorption structure and the contour-following pressure-holding structure are mounted on the first template 11. Specifically, the vacuum-drawing mechanism can be directly connected to the first template 11 or to the second template 12. When the vacuum-drawing mechanism is connected to the second template 12, an additional vacuum adsorption structure needs to be provided on the second template 12.

[0043] Reference Figure 1 and Figure 2 As shown, a third vacuum adsorption structure is provided on the second template 12. The third vacuum adsorption structure includes a third adsorption hole 431 and a third suction hole 432 that are interconnected. The third adsorption hole 431 is connected to the first suction hole 412 provided on the first template 11, thereby enabling the transfer of vacuum adsorption. Specifically, in this embodiment, the first suction hole 412 on the first template 11 is located on the side of the first template 11, and the third adsorption hole 431 on the second template 12 is located on the side of the second template 12. At the same time, a connector 415 can be provided at the first suction hole 412 on the first template 11 and the third adsorption hole 431 on the second template 12, and they can be connected by a connecting pipe to achieve the transfer of vacuum adsorption, so that the vacuum pumping mechanism can be connected to the second template 12. In addition to the connecting pipe method, it can also be set to be directly connected by a method such as an interface, and this utility model does not limit this.

[0044] In some possible implementations, a positioning structure 414 may be provided on the surface of the first mold 1 for mounting the first part of the product to be assembled. This positioning structure 414 is used to assist the first mold 1 in accurately mounting onto the second mold 2. Specifically, the positioning structure 414 can be configured to combine with a corresponding structure on the second mold 2 to achieve the auxiliary positioning function, or it can be configured to combine with the structure of the second part of the product to be assembled mounted on the second mold 2 to achieve the auxiliary positioning function. The specific structure of the positioning structure 414 can be designed according to the structural style to be combined with it in the actual design; this utility model does not impose any limitations on this.

[0045] Reference Figures 2 to 4 As shown, in this embodiment, the positioning structure 414 is configured as a positioning insert 4141 on the first mold 1. (Refer to...) Figure 3 and Figure 4 As shown, the positioning insert 4141 corresponds to the structure on the second part of the product to be assembled, which is mounted on the second mold 2. Since the first part of the product to be assembled is fixed on the first mold 1, the position between the first part of the product to be assembled and the positioning insert 4141 is relatively fixed. By setting the positioning insert 4141 to correspond to the structure on the second part of the product to be assembled, the position of the second part of the product to be assembled can also be relatively fixed with respect to the positioning insert 4141, thereby ensuring the assembly accuracy of the product to be assembled.

[0046] Of course, the positioning insert 4141 can also be set to correspond to the structure on the second mold 2, but in this case, it is necessary to further ensure the installation accuracy of the second part of the product to be assembled on the second mold 2 in order to ensure the accuracy of the insert 4141 after assembly.

[0047] It is understood that the structure of the second mold 2 can be the same as or different from the structure of the first mold 1. Embodiments where the structure of the second mold 2 is the same as that of the first mold 1 will not be described further here. In other embodiments of the second mold 2, in some possible implementations, the second mold 2 can be configured to use positioning pins 21 and positioning knobs 22 to press together the second part of the product to be assembled.

[0048] Reference Figures 5 to 7As shown, the second mold 2 is provided with positioning posts 21, so that the second part of the product to be assembled can be installed on the positioning posts 21 to achieve the installation and positioning of the second mold 2. The positioning knob 22 can be turned off to facilitate the installation of the second part of the product to be assembled. After the second part of the product to be assembled is installed on the second mold 2, the positioning knob 22 can be turned to press it onto the second mold 2, thus realizing the installation of the second part of the product to be assembled.

[0049] Furthermore, the first detachable connection structure 31 provided on the first mold 1 and the second mold 2 is a structure used to fix the first mold 1 and the second mold 2 in a combined state. Specifically, the first detachable connection structure 31 only needs to satisfy the above-mentioned function, and it can be set as other structures commonly used in the prior art. (Refer to...) Figure 1 and Figure 3 As shown, in this embodiment, the first detachable connection structure 31 is implemented as a snap-fit ​​structure. The snap-fit ​​structure includes a snap block 311 rotatably mounted on the first mold 1 and a snap block 312 integrally mounted on the second mold 2. The ends of the snap block 311 and the snap block 312 can be engaged with each other. The first mold 1 is also provided with a spring for driving the snap block 311 to rotate and engage with the snap block 312. Both the ends of the snap block 311 and the snap block 312 are provided with inclined surfaces. Therefore, in use, it is only necessary to align the positions of the first mold 1 and the second mold 2 to make the snap block 311 and the snap block 312 engage with each other, thereby realizing the assembly between the first mold 1 and the second mold 2.

[0050] It is understood that the above-described embodiments are only one implementation of the first detachable connection structure 31 in the form of a snap-fit ​​structure. The snap-fit ​​structure can also be set to other snap-fit ​​methods commonly used in the prior art, or the first detachable connection can also be set to other structures such as a hook structure, a magnetic structure, or a rotary buckle structure. This utility model does not limit these aspects.

[0051] When using the first mold 1 and the second mold 2, the operator can install the first part and the second part of the product to be assembled onto the first mold 1 and the second mold 2 respectively. Then, the positioning insert 4141 on the first mold 1 is aligned with the second part of the product to be assembled on the second mold 2. Finally, the first mold 1 and the second mold 2 are pressed together, and the second template 12 on the first mold 1 and the second mold 2 are fastened together using the first detachable connecting structure 31 to complete the installation. At this time, the elastic structure between the second template 12 and the first template 11 will apply pressure to the first template 11, realizing the pressure holding function of the product to be assembled.

[0052] Figure 8 The diagram schematically illustrates the structural composition of an integrated pressure-holding fixture according to another embodiment of this utility model. (Refer to...) Figure 8 As shown, it also includes a base 5, on which a drive assembly 6 is disposed. The drive assembly 6 is a structure for mounting the first mold 1 and driving the first mold 1 to move toward the second mold 2. The drive assembly 6 is provided with a movable end 61 that is driven to move, and the first mold 1 is detachably disposed on the movable end 61. The second mold 2 is detachably disposed on the base 5 through a second detachable connection structure 32.

[0053] Specifically, the main function of base 5 is to support the overall fixture, as shown in the reference. Figure 8 As shown, the base 5 includes a square base 51 and a bracket 52 disposed on the base 51. The drive assembly 6 is mounted on the bracket 52, and the second detachable connection structure 32 is disposed on the base 51.

[0054] Since the first mold 1 and the drive component 6 are detachably connected, and the second mold 2 and the base 5 are also detachably connected, after the first mold 1 is assembled onto the second mold 2 using the drive component 6, it can be completely removed from the base 5 and directly transferred for baking. This effectively avoids various component displacement problems that may occur when the assembled product is transferred to the pressure baking fixture.

[0055] The drive assembly 6 can be configured as an automated drive assembly 6 commonly used in existing technologies, such as a pneumatic cylinder or a hydraulic cylinder. Alternatively, it can be configured as a manually operated drive assembly 6. For example, refer to... Figure 8 As shown, in Figure 8 In the illustrated embodiment, the drive component 6 is specifically configured as a quick-clamp structure with a handle 62. This quick-clamp structure is mounted on the bracket 52 to control the up-and-down movement of its movable end 61. The specific structural design of the quick-clamp structure can be based on existing technology; therefore, this aspect will not be elaborated upon here. With this design, the operator can control the up-and-down movement of the movable end 61 of the drive component 6 by operating the handle 62, thereby controlling the up-and-down movement of the first mold 1 connected to the movable end 61.

[0056] The movable end 61 of the drive component 6 may be provided with a connecting plate structure 63 for connection with the first mold 1. In an embodiment where the first mold 1 is provided with a first template 11 and a second template 12, the connecting plate structure 63 may be configured to connect with the second template 12.

[0057] Since the first mold 1 is configured to install the first part of the product to be assembled through the first vacuum adsorption structure, the first mold 1 needs to be equipped with a vacuuming mechanism. However, since the first mold 1 also needs to be removed from the base 5, the vacuuming mechanism can be set on the connecting plate structure 63 to facilitate the disassembly of the first mold 1 and the second mold 2.

[0058] Specifically, a second vacuum adsorption structure can be provided on the connecting plate structure 63. The second vacuum adsorption structure includes a second adsorption hole 421 and a second suction hole 422 that are interconnected. The second adsorption hole 421 is configured to communicate with the first suction hole 412 when the first mold 1 is installed on the connecting plate structure 63. At this time, the second suction hole 422 is connected to a mechanism for vacuuming, so that the first part of the product to be assembled can be installed when the first mold 1 is installed on the connecting plate structure 63.

[0059] For example, refer to Figure 9 and Figure 10 As shown, in this embodiment, the second suction hole 422 on the connecting plate structure 63 is located on the side of the connecting plate structure 63, while the second adsorption hole 421 is located on the side of the connecting plate structure 63 used for connection with the first mold 1. The third suction hole 432 of the second template 12 in the first mold 1 is located on the side of the second template 12 used for connection with the connecting plate structure 63. Therefore, when the connecting plate structure 63 is connected to the second template 12, the third suction hole 432 and the second adsorption hole 421 are positioned opposite each other, achieving communication between them. This allows communication between the second adsorption hole 421 and the first suction hole 412, enabling the adsorption of the first part of the product to be assembled through the second suction hole 422. In addition, a sealing structure 423 is provided on the outer periphery of the second adsorption hole 421. The sealing structure 423 can be formed of materials such as compressed foam or rubber to ensure the sealing between the second adsorption hole 421 and the third suction hole 432 after the connecting plate structure 63 is connected to the first mold 1. At this point, the vacuuming mechanism can be directly connected to the second air extraction hole 422 of the connecting plate structure 63, thereby avoiding the need to further disassemble the vacuuming mechanism when disassembling the first mold 1.

[0060] The detachable connection between the first mold 1 and the connecting plate structure 63 can be achieved using a magnetic attraction structure. Compared with other detachable connection structures, the magnetic attraction structure has a certain self-positioning performance, thereby ensuring the positional accuracy of the first mold 1 when it is installed on the connecting plate structure 63. Furthermore, the magnetic attraction structure allows the first mold 1 to automatically detach from the connecting plate structure 63 when subjected to a larger external force. Thus, when the operator controls the drive assembly 6 to assemble the first mold 1 onto the second mold 2, since the first mold 1 is relatively fixed to the second mold 2 by the first detachable connection structure 31, when the operator controls the drive assembly 6 to rise, the first mold 1 will detach from the movable end 61 of the drive assembly 6, achieving automatic detachment of the first mold 1. The specific location of the magnetic attraction structure can be freely set according to actual conditions, and this invention does not impose any restrictions on this. Alternatively, other detachable connection structures can also be used to connect the first mold 1 and the connecting plate structure 63, and this invention does not impose any restrictions on this either.

[0061] The connecting plate structure 63 may include a first mounting plate 631 and a second mounting plate 632. The first mounting plate 631 is disposed on the movable end 61, and the second mounting plate 632 is mounted on the first mounting plate 631 for mounting the first mold 1. In this embodiment, the second mounting plate 632 and the first mounting plate 631 can be connected by mounting with equal-height screws, and gaps are left between the equal-height screws axially and between the equal-height screws and the first mounting plate 631, as well as between the equal-height screws circumferentially and the first mounting plate 631. This arrangement allows the second mounting plate 632 to adaptively adjust its position according to the assembly position between the first mold 1 and the second mold 2 when the drive assembly 6 controls the movement of the first mold 1, avoiding the installation position of the first mold 1 when assembled onto the second mold 2 due to installation accuracy errors between the first mold 1 and the second mounting plate 632, thus ensuring the assembly accuracy between the first mold 1 and the second mold 2.

[0062] The second detachable connection structure 32 between the second mold 2 and the base 5 can be configured as a detachable connection structure in any of the embodiments described above. In this embodiment, in order to make the installation and disassembly between the second mold 2 and the base 5 more convenient, the second detachable connection structure 32 can be configured to include a locking block 311 structure disposed on the second mold 2 and a limiting structure disposed on the base 5 that matches the locking block 311 structure.

[0063] Specifically, refer to Figure 7 and Figure 11 As shown, the limiting structure is disposed on the upper surface of the base 51, including the structure disposed on... Figure 11The L-shaped limiting blocks 321 on both sides in the X direction and the rear side in the Y direction of the second mold 2 form a sliding groove between the L-shaped limiting blocks 321 and the base 51. (Refer to...) Figure 7 As shown, the locking block 311 structure includes protruding edges 322 on both sides in the X direction and the rear side in the Y direction of the second mold 2. Therefore, the second mold 2 can be slidably mounted onto the base 51 from the front side in the Y direction. Simultaneously, a rotating plunger 323 can also be provided on the second mold 2 to press it firmly, achieving complete installation of the second mold 2.

[0064] In addition, in some possible implementations, reference continues to be made to Figure 11 As shown, a base plate 53 can also be slidably mounted on the base 51, and the aforementioned limiting structure is mounted on the base plate 53 to achieve mounting on the base 51. Specifically, a slide rail 54 is provided between the base plate 53 and the base 51 to achieve a sliding connection. Simultaneously, a stop block 55 can be provided on the base 51 to block the base plate 53 at a first extreme position, allowing the base plate 53 to slide between the first extreme position and the second extreme position. The first extreme position is the position corresponding to the position of the second mold 2 and the first mold 1, while the second extreme position is the extreme position where the base plate 53 slides in the opposite direction. For example, Figure 12 This represents the state of the base plate 53 when it slides to its first extreme position. Figure 8 This is the state when the base plate 53 slides to the second limit position.

[0065] When using this integrated assembly and pressure-holding fixture, the base plate 53 needs to be slid to its second limit position first. Then, the second mold 2, with the second part of the product to be assembled already installed, is mounted onto the base plate 53. Simultaneously, the first mold 1 is first mounted onto the movable end 61 of the drive assembly 6, and then the first part of the product to be assembled is mounted onto the first mold 1. Afterward, the base plate 53 is slid to its first limit position to align the first mold 1 and the second mold 2. The operator then uses the quick-clamp structure to press down, assembling the first mold 1 and the second mold 2. When the operator lifts the quick-clamp structure, the first mold 1 is assembled onto the second mold 2 due to the magnetic connection between the first mold 1 and the drive assembly 6. Finally, the base plate 53 is slid to its second limit position, and the assembled first mold 1 and second mold 2 are disassembled and moved to the baking stage.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
