Description

Technical Field

[0001] This application relates to the field of product assembly tooling technology, and in particular to a pressure holding device. Background Technology

[0002] In the assembly process of electronic products, it is often necessary to bond two different components with adhesive. Sufficient pressure must be applied to both components during bonding to ensure proper alignment and assembly accuracy. This bonding process needs to be maintained for a period of time to allow the adhesive to fully cure, ultimately connecting and fixing the two components in a specific positional relationship to form a complete product. This bonding process is generally achieved through a pressure-holding procedure using a pressure-holding device.

[0003] In actual production, workpieces typically require pressure holding at multiple locations, with different pressure data requirements and holding times for each angle. Furthermore, for irregular products requiring multi-point, multi-pressure holding, due to the product's unique shape and the need for multiple pressure parameters, the pressure holding devices commonly used in the industry are generally only suitable for one specific product. Using different pressure holding devices for different products not only results in low versatility but also in high holding costs. Utility Model Content

Therefore, they should not be construed as limitations on this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same component or part. For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.

[0033] This application provides a pressure-holding device that solves the problem that existing pressure-holding devices can only hold pressure for one type of product, and different products require different pressure-holding devices, which not only has low versatility but also high pressure-holding costs.

[0034] refer to Figure 1The pressure-holding device provided in this application includes a mounting frame 1, a pressing assembly 2, and a pressing mold assembly. The mounting frame 1 includes a base 11, a top seat 12, and two support columns 13 spaced apart between the base 11 and the top seat 12. The pressing assembly 2 includes a mounting seat 21 on the top seat 12, a first driving member on the mounting seat 21, guide rails 22 on two outer sides of the mounting seat 21 along a first direction, and a pressing member 23 slidably connected to the guide rails 22. The first driving member is connected to the pressing member 23 and is used to drive the pressing member 23 to move closer to or away from the base 11. The pressing mold assembly... The assembly includes a separable upper mold 3 and a lower mold 4, which together form a receiving space for accommodating the product when connected. The upper mold 3 includes an upper mold component and a pressure plate 31 and a pressure head 32 detachably connected to the upper mold component. The upper mold component is connected to the side of the lower mold component 23 near the base 11. The lower mold 4 is disposed on the base 11 and includes a support plate 41, a carrier 42 disposed on the support plate 41, and a positioning component 43 detachably disposed around the carrier 42. The positioning component 43 is used to abut the product to be pressurized when the carrier 42 carries the product to be pressurized.

[0035] In this application, the product to be pressurized by the pressurizing device is a semi-finished product formed by bonding two parts together with adhesive, and the bonding strength is relatively small.

[0036] The specific process of the pressure-holding device in this embodiment of the application for holding the pressure on the product to be held is as follows: the product to be held is placed on the carrier 42 of the lower mold 4, and the lower pressing member 23 is driven to move towards the base 11 by the first driving member. The upper mold member connected to the lower pressing member 23 will also move towards the base 11. In this way, the pressure plate 31 and the pressure head 32 connected to the upper mold member will move towards the base 11, thereby pressing on the product to be held. The product to be held is then fixed in the receiving space formed by the upper mold 3 and the lower mold 4. By applying pressure to the product to be pressurized using the pressure plate 31 and the pressure head 32 and maintaining it for a certain period of time, the purpose of pressurizing the product to be pressurized can be achieved. After the pressurization is completed, the lower pressure member 23 is driven by the first driving member to move away from the base 11. The upper pressure mold member connected to the lower pressure member 23 will also move away from the base 11. In this way, the pressure plate 31 and the pressure head 32 connected to the upper pressure mold member will move away from the base 11 and leave the product to be pressurized, so that the staff can take out the product to be pressurized that has completed the pressurization on the carrier 42.

[0037] In practical applications, the pressure-holding device of this application can be used in conjunction with other production equipment. For example, after the initial bonding of two parts bonded together, the product to be pressure-held is directly transferred to the pressure-holding device via a transfer track. Specifically, it is transferred from one side of the pressure-holding device to the carrier 42 along the first direction. After the pressure holding is completed, it is transferred out from the other side of the pressure-holding device. The product to be pressure-held after pressure holding is completed can be directly transferred to the assembly line. After the product to be pressure-held on the carrier 42 is removed, the next product to be pressure-held can be transferred to the carrier 42 for pressure holding. In this way, continuous pressure holding of batch products can be realized, which greatly improves the pressure holding efficiency of batch products.

[0038] It should be noted that the mounting base 21 of the pressing component 2 is located on the top base 12, and the mounting base 21 has guide rails 22 on its two outer sides along the first direction. Pressing components 23 are slidably connected to the guide rails 22, meaning that two pressing components 23 are spaced apart along the first direction. When the first direction is perpendicular to the arrangement direction of the two support columns 13, the product to be pressurized is transferred to the carrier 42 along the first direction, and the two pressing components 23 respectively drive the pressure plate 31 and the pressure head 32 downwards along both sides of the first direction to press the product to be pressurized. When the first direction is parallel to the arrangement direction of the two support columns 13, the product to be pressurized is transferred to the carrier 42 along a direction perpendicular to the first direction, and the two pressing components 23 respectively drive the pressure plate 31 and the pressure head 32 downwards along both sides of the first direction to press the product to be pressurized.

[0039] Since the product to be pressurized is usually pressurized in a localized area, this embodiment of the application simultaneously sets up a pressure plate 31 and a pressure head 32 to apply pressure to the product to be pressurized. The pressure plate 31 presses the entire surface of the product to be pressurized, so that the product to be pressurized is fixed between the pressure plate 31 and the carrier 42. Then, the pressure head 32 applies pressure to the localized area of ​​the product to be pressurized, thereby achieving the pressurization effect of the product to be pressurized.

[0040] In this embodiment, both the pressure plate 31 and the pressure head 32 are detachably connected to the upper pressure mold. This allows for the replacement of different pressure plates 31 and their corresponding pressure heads 32 when using the pressure-holding device of this application to hold different products. This makes the shape of the replaced pressure plate 31 more compatible with the shape of different products and allows the replaced pressure head 32 to apply pressure to the local areas on different products that require pressure holding. As a result, the pressure-holding device can hold different products and improve its versatility.

[0041] In addition, the positioning element 43 of this application is also detachably mounted on the support plate 41. The positioning element 43 can fix the product to be pressurized on the carrier 42, so as to prevent the product to be pressurized from moving when the pressure plate 31 is pressed down, which would cause the pressure head 32 to be unable to accurately apply pressure to the local position of the product to be pressurized, thus affecting the pressurization effect. Therefore, by detachably mounting the positioning member 43 on the support plate 41, the installation position of the positioning member 43 on the support plate 41 can be changed when the product to be pressurized changes. That is, the relative position between the positioning member 43 and the carrier 42 can be adjusted so that the positioning member 43 after the position is adjusted can adapt to the shape of the changed product to be pressurized, thereby better fixing the changed product to be pressurized. This is beneficial for the pressurizing device to pressurize different products to be pressurized, effectively improving the versatility of the pressurizing device. Compared with the prior art, where a product to be pressurized can only be pressurized by a specific pressurizing device, and different products to be pressurized require different pressurizing devices, increasing the pressurizing cost, the pressurizing device of this application embodiment can pressurize different products to be pressurized, greatly reducing the cost of pressurizing different products to be pressurized and improving the efficiency of pressurizing different products to be pressurized.

[0042] In some embodiments, reference Figure 1 The positioning component 43 includes multiple fixed positioning blocks 431 and multiple movable positioning blocks 432. The movable positioning blocks 432 are connected to a second driving component, which is used to drive the movable positioning blocks 432 to move closer to or away from the carrier 42.

[0043] It should be noted that the fixed positioning block 431 cannot be adjusted after it is set. If the position needs to be adjusted, the fixed positioning block 431 needs to be removed and repositioned in another position. The movable positioning block 432, on the other hand, can be adjusted after it is set. Setting multiple fixed positioning blocks 431 and multiple movable positioning blocks 432 around the carrier 42 at the same time can better fix the product to be pressure-held on the carrier 42.

[0044] Specifically, the arrangement of multiple fixed positioning blocks 431 and multiple movable positioning blocks 432 around the carrier 42 can be as follows: along a direction perpendicular to the arrangement direction of the two support columns 13, multiple fixed positioning blocks 431 can be set on both sides of the carrier 42, and along the arrangement direction of the two support columns 13, multiple movable positioning blocks 432 can be set on both sides of the carrier 42. This combination of fixed positioning blocks 431 and movable positioning blocks 432 to fix the product to be pressurized improves the positioning effect of the product on the carrier 42. When the pressure plate 31 presses the product to be pressurized, the product will not move, thus not affecting the pressure-holding effect.

[0045] For example, there are four fixed positioning blocks 431, two fixed positioning blocks 431 are respectively set on both sides of the carrier 42, and two movable positioning blocks 432 are respectively set on both sides of the carrier 42. After the product to be pressure-held is placed on the carrier 42, the product to be pressure-held is first fixed by the fixed positioning blocks 431 to restrict the movement of the product to be pressure-held in the direction perpendicular to the arrangement direction of the two support columns 13. Then, the movable positioning blocks 432 are driven by the second driving member to approach the carrier 42 to abut against the product to be pressure-held, thereby restricting the movement of the product to be pressure-held in the arrangement direction of the two support columns 13.

[0046] Of course, the arrangement of the multiple fixed positioning blocks 431 and multiple movable positioning blocks 432 around the carrier 42 can also be as follows: along the arrangement direction of the two support columns 13, the multiple fixed positioning blocks 431 can be set on both sides of the carrier 42, and along the direction perpendicular to the arrangement direction of the two support columns 13, the multiple movable positioning blocks 432 can be set on both sides of the carrier 42. This can also improve the positioning effect of the product to be pressure-held on the carrier 42.

[0047] The arrangement of multiple fixed positioning blocks 431 and multiple movable positioning blocks 432 around the vehicle 42 can also be as follows: multiple fixed positioning blocks 431 can be set on two adjacent sides of the vehicle 42, and multiple movable positioning blocks 432 can be set on two other adjacent sides of the vehicle 42.

[0048] In some embodiments, reference Figure 2 The upper pressing mold includes a fixed plate 30 and an elastic member 33 connected to the fixed plate 30. The pressure plate 31 and the pressure head 32 are detachably connected to the elastic member 33. The fixed plate 30 is connected to the side of the lower pressing member 23 near the base 11.

[0049] The aforementioned elastic element 33 can be a spring, an elastic sheet, or other elastic object.

[0050] With the above settings, the pressure plate 31 and the pressure head 32 can be replaced when the product to be pressured by the pressure holding device changes, so that the shape of the pressure plate 31 can better match the shape of the changed product to be pressured, and can better fix the product to be pressured on the carrier 42. At the same time, the pressure head 32 can also match the local position and pressure of the changed product to be pressured, so as to accurately apply pressure to the local position of the product to be pressured for pressure holding, which greatly improves the pressure holding effect of the product to be pressured.

[0051] Both the pressure plate 31 and the pressure head 32 are connected to the fixed plate 30 via the elastic element 33. When the pressure plate 31 and the pressure head 32 press on the product to be pressed, if the pressure is too high, the elastic element 33 will be squeezed and contracted. Thus, the elastic element 33 will apply an elastic force to the product to be pressed, which not only positions the product to be pressed more stably on the carrier 42, but also avoids the pressure plate 31 and the pressure head 32 applying too much force to the product to be pressed, which could damage the product due to the lack of buffer.

[0052] Furthermore, the connection between the upper pressure mold and the lower pressure component 23 is achieved by connecting the fixing plate 30 to the side of the lower pressure component 23 near the base 11. Since the mounting base 21 is provided with lower pressure components 23 on both sides along the first direction, connecting the lower pressure component 23 to the fixing plate 30 can ensure that the lower pressure components 23 located on both sides of the mounting base 21 along the first direction maintain a consistent pressing speed and pressing distance when pressing down. This makes the pressure of the pressure plate 31 on each position of the product to be pressed more uniform, and better fixes the product to be pressed on the carrier 42. On this basis, the pressure head 32 can press down on the local position of the product to be pressed to improve the pressure holding effect of the product.

[0053] It is understandable that both sides of the fixing plate 30 are horizontal and the thickness of the fixing plate 30 is uniform. This ensures that different pressing parts 23 maintain the same pressing speed and move downwards for the same distance, and that the pressure plate 31 can move downwards while remaining on the horizontal surface until it presses the product to be held under pressure.

[0054] In some embodiments, reference Figure 2 The upper pressure mold also includes a first positioning post 34 connected to the fixed plate 30. The bearing plate 41 is provided with a positioning hole 411. The first positioning post 34 is inserted into the positioning hole 411 so that the product to be pressure-held is fixed in the accommodating space.

[0055] With the above settings, when the upper pressure mold presses down on the product to be pressed, the first positioning pin 34 will be inserted into the positioning hole 411, thereby limiting the lower pressure member 23 from driving the fixing plate 30 to continue pressing downward. At this time, the product to be pressed is fixed between the pressure plate 31 and the carrier 42. The setting of the first positioning pin 34 can limit the distance that the lower pressure member 23 moves towards the base 11, preventing the pressure plate 31 from pressing the product to be pressed onto the carrier 42 after it has already pressed the product to be pressed down, which would cause the product to be pressed to bear excessive pressure and be damaged.

[0056] The system can have multiple first positioning pins 34, and the number of positioning holes 411 is equal to the number of first positioning pins 34. Each first positioning pin 34 is inserted into one positioning hole 411. (Reference) Figure 2The number of first positioning pins 34 is set to four, which are distributed on the four sides of the fixing plate 30. Four positioning holes 411 are provided on the bearing plate 41, and the four positioning holes 411 correspond one-to-one with the four positioning pins, so that the first positioning pins 34 can be inserted into the positioning holes 411.

[0057] In some embodiments, reference Figure 2 The upper pressure mold also includes a second positioning post 35 connected to the fixed plate 30. The bearing plate 41 is provided with a positioning cylinder 412 that can move along the thickness direction of the bearing plate 41. The second positioning post 35 is inserted into the positioning cylinder 412 so that the product to be pressure-held is fixed in the accommodating space.

[0058] The positioning cylinder 412 is a cylindrical structure with an opening, through which the second positioning pin 35 is inserted. The positioning cylinder 412 can move along the thickness direction of the support plate 41 by connecting a spring to the outer surface of the bottom wall of the positioning cylinder 412 opposite to the opening, and connecting the other end of the spring to a support seat below the support plate 41. Under the elastic force of the spring, the positioning cylinder 412 will move along the thickness direction of the support plate 41.

[0059] With the above settings, when the upper pressure mold presses down on the product to be pressured, the first positioning pin 34 will be inserted into the positioning hole 411, and the second positioning pin 35 will be inserted into the positioning cylinder 412. Specifically, the length of the second positioning pin 35 can be set to be greater than the length of the first positioning pin 34. After the second positioning pin 35 is inserted into the positioning cylinder 412, it will press the positioning cylinder 412 downward, and the spring connected to the positioning cylinder 412 will be compressed. Since the downward pressing distance of the second positioning pin 35 is greater than the downward pressing distance of the first positioning pin 34, the elastic element 33 connected to the pressure plate 31 will be compressed after the pressure plate 31 presses on the product to be pressured, thereby applying elastic force to the product to be pressured, which is conducive to the product to be pressured being more stably fixed on the carrier 42, ensuring the normal operation of the pressure holding work.

[0060] By combining the first positioning post 34 and the second positioning post 35, the downward pressing distance of the pressing member 23 can be effectively limited, preventing the pressure plate 31 from applying excessive pressure to the product to be pressed, which could damage the product.

[0061] In some embodiments, the upper pressing mold further includes a first heating device, which is disposed on the side of the pressure plate 31 near the fixed plate 30. Thus, when the pressure plate 31 presses down on the product to be pressed, the first heating device can heat the product, allowing the adhesive between the two components of the product to be fully cured, resulting in better pressure retention.

[0062] In some embodiments, the lower mold 4 further includes a second heating device, which is disposed on the side of the support plate 41 opposite to the carrier 42. Since the product to be pressed is located between the carrier 42 and the pressure plate 31 during the pressing process, the carrier 42 and the pressure plate 31 simultaneously apply extrusion force to the product to be pressed, so that the two parts of the product to be pressed are aligned and fitted together. The second heating device disposed on the side of the support plate 41 opposite to the carrier 42 can heat the product to be pressed, thereby allowing the adhesive between the two parts of the product to be pressed to be fully cured, resulting in a better pressing effect.

[0063] In some embodiments, reference Figure 2 The mounting base 21 includes a first mounting plate 211 connected to the top base 12 and a second mounting plate 212 disposed on both sides of the first mounting plate 211 along a first direction; the second mounting plate 212 is provided with an observation hole 2120 that passes through the second mounting plate 212, and the orthographic projection of the guide rail 22 on the second mounting plate 212 at least partially covers the observation hole 2120.

[0064] It should be noted that by installing the guide rail 22 on the outer side of the second mounting plate 212 and providing an observation hole 2120 on the second mounting plate 212, the staff can observe the installation status of the guide rail 22 through the observation hole 2120 when installing the guide rail 22, which is conducive to smoother assembly of the guide rail 22.

[0065] In some embodiments, reference Figure 2 The top seat 12 is provided with a through hole, and the first mounting plate 211 is provided with a threaded hole. The first mounting plate 211 and the top seat 12 are connected by bolts.

[0066] It should be noted that, in order to reduce costs, the pressure holding device in this application embodiment is generally made of cast iron to form the mounting bracket 1, while the mounting base 21 is usually made of steel because it needs to connect the first driving component and the guide rail 22. Since the density of cast iron is lower than that of steel, when the mounting base 21 is connected to the top base 12 by bolts, through holes can be provided on the top base 12, and threaded holes can be provided on the first mounting plate 211 of the mounting base 21. In this way, the mounting base 21 can be connected to the top base 12 by bolts, while avoiding the risk of cracking and scrapping of the top base 12 due to the threaded holes.

[0067] In some embodiments, reference Figure 2 The number of pressing components 2 is multiple, and the multiple pressing components 2 are arranged side by side along the arrangement direction of the two support columns 13; the number of pressing mold components is multiple, and the multiple pressing mold components are arranged side by side along the arrangement direction of the two support columns 13.

[0068] It should be noted that if a pressing component 2 and a molding component are regarded as a pressure holding group, then this application sets multiple pressing components 2 and multiple molding components, which is equivalent to setting multiple pressure holding groups. The multiple pressure holding groups are arranged side by side along the arrangement direction of the two support columns 13. Each pressure holding group presses one product to be pressurized at a time. Thus, multiple pressure holding groups can press multiple products to be pressurized at the same time, which greatly improves the pressure holding efficiency of batch products to be pressurized.

[0069] Example, reference Figure 1 Two pressing components 2 and two pressing mold components are set. The two pressing parts 23 of each pressing component 2 are located on both sides of the mounting base 21 along the first direction. Here, the first direction is perpendicular to the arrangement direction of the two support columns 13. The mounting base 21 of the two pressing components 2 can be set to the same one, and the guide rails 22 of the two pressing components 2 can be set on the same mounting base 21. This can reduce the workload of connecting the pressing components 2 to the top seat 12 and improve the assembly efficiency of the pressing components 2.

[0070] When the two pressing parts 23 of the pressing assembly 2 are located on both sides of the mounting base 21 along the first direction, the carriers 42 of the two pressing dies 4 are arranged adjacently along the arrangement direction of the two support columns 13. In this way, the two sides of the carriers 42 along the first direction are connected to the outside world, which will not affect the transfer of the product to be pressed from other production lines to the carriers 42 along the first direction, or the transfer from the carriers 42 to the next assembly production line along the first direction after the pressing is completed. The two pressing assemblies 2 and the two pressing die assemblies can be arranged in the above manner, which can not only press two products to be pressed at the same time, but also make the arrangement more compact and the space utilization better. Compared with the pressing device in the prior art, which can only press one product to be pressed at a time, the pressing device of this application, although it is equipped with two pressing assemblies 2 and two pressing die assemblies, still does not increase the volume of the pressing device excessively.

[0071] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
