Description

Technical Field

[0001] The utility model relates to the technical field of PU cloth and silicone product composites, in particular to a PU cloth and silicone product composite fixture box. Background Art

[0002] Existing PU fabric and silicone products are generally assembled and bonded using glue, including structural glue, epoxy resin glue, polyurethane glue, acrylic glue and RTV room temperature vulcanized silicone. However, many types of glue require a long time and pressure to fully cure.

[0003] The existing curing and assembly process for PU fabric and silicone products is as follows: the silicone product is first placed on a small jig, then glue is applied to the product. The PU fabric and silicone product are then pre-pressed for a certain period of time. The small jig and product are then transferred together to a larger hydraulic press for pressurization. Using a large hydraulic press, multiple small jigs must be pressed together at once, while simultaneously maintaining pressure and curing. This pressing and curing must continue for more than 24 hours. However, this approach results in a huge demand for pressure-maintaining equipment and the need to manufacture a large number of jigs, which will occupy a large amount of pressure-maintaining equipment and jig resources. Moreover, during the pressure-maintaining and curing process, multiple jigs are pressurized together, and the pressure on each jig may be uneven, making it difficult to ultimately achieve the product's required bond strength. Furthermore, during the product development and verification phase, using a single pressure-maintaining device to simultaneously maintain pressure on multiple jigs makes multi-parameter verification difficult. Verification can only be performed using multiple devices, further increasing the demand for pressure-maintaining equipment. Utility Model Content

[0040] The existing PU cloth 13 and silicone product 12 are generally assembled and bonded by glue, but many types of glue require a long time and need to be pressurized to fully cure. However, the existing PU cloth 13 and silicone product 12 are generally pre-pressed by gluing, and then transferred to the hydraulic press for pressurization. A large hydraulic press is used, and multiple small jigs need to be pressed at one time, and pressure-maintained and cured at the same time. The pressing and curing are continued for more than 24 hours. However, during the transfer process. The above-mentioned product processing process will cause the pressure-maintaining equipment resources to be greatly occupied, the pressure caused by multiple jigs being pressurized together will be uneven, making it difficult to meet the product's requirements for bonding strength, and there is a risk that the PU cloth 13 and silicone product 12 will loosen during the turnover process to the large hydraulic press. Therefore, a PU cloth and silicone product composite jig box is provided. It should be noted that the above-mentioned PU cloth 13 is a component in this embodiment, specifically including the PU cloth body and FPCBA, which are bonded together using 3M double-sided tape.

[0041] Specifically, such as Figure 1-6As shown, the embodiment of the present invention discloses a PU cloth and silicone product composite fixture box, which specifically includes an upper shell 1, a lower shell 2 and a snap assembly 3, wherein the inner bottom side wall of the upper shell 1 is provided with a fixing piece, which is used to fix the PU cloth 13; the inner bottom side wall of the lower shell 2 is provided with a placement groove 5, and the silicone product 12 is placed on the placement groove 5, wherein the lower half of the silicone product 12 is located in the placement groove 5 and matches the placement groove 5, and the upper part of the silicone product 12 is located above the placement groove 5; wherein, in order to ensure that the PU cloth 13 and the silicone product 12 are pressurized and solidified, the silicone product 12 is placed On the placement groove 5, glue is applied to the upper side wall of the silicone product 12, and the PU cloth 13 is fixed on the upper shell 1. Finally, the upper shell 1 and the lower shell 2 are fastened together through the snap assembly 3 to form a whole, so that the lower side wall of the PU cloth 13 located in the jig box is pressed tightly against the upper side wall of the silicone product 12. Therefore, under the action of the snap assembly 3, the upper shell 1 and the lower shell 2 continuously apply pressure to the two, which can make the upper side wall of the silicone product 12 continuously abut against the lower side wall of the PU cloth 13, play a role of continuous pressurization, thereby maintaining pressure and curing the PU cloth 13 and the silicone product 12.

[0042] The jig box composed of the above-mentioned upper shell 1, lower shell 2 and snap assembly 3 can replace the hydraulic press or air press to perform pressure maintenance and curing, and there is no need to occupy pressure maintenance resources such as hydraulic press or air press, saving equipment costs; furthermore, the PU cloth 13 and the silicone product 12 are placed in the jig box at the same time. When the jig box is locked, the jig box always maintains pressure on the PU cloth 13 and the silicone product 12, thereby eliminating the pre-pressing step and the moving step in the existing curing process, reducing the production process, and at the same time, it can also perform pressure maintenance on multiple jig boxes to improve production efficiency, and one jig only performs pressure maintenance and curing on one product, so that the bonding strength of a single product is better achieved, ensuring the qualified rate of the product after curing; finally, the upper and lower shell jigs are injection molded using plastic materials, which can meet mass production needs, have low cost, and can be replaced immediately once damaged, with strong replaceability.

[0043] Specifically, the fixing part includes a fixing column 4, which is made of plastic material. There are multiple fixing columns 4, and multiple limiting holes are set at the outer end of the PU cloth 13. When installing the PU cloth 13 on the upper shell 1, it is only necessary to insert the multiple limiting holes on the multiple PU cloths 13 into the multiple fixing columns 4 one by one. After insertion, the fixing columns 4 and the limiting holes are transitionally matched, thereby limiting the PU cloth 13 on the upper shell 1. The position is accurate, the operation is simple and convenient, and it is also convenient to disassemble.

[0044] Specifically, in order to avoid the silicone product 12 from deviating too much outward when the PU cloth 13 and the silicone product 12 are pressed together, thereby causing the final gluing position to be inaccurate, in this embodiment, a limit plate 6 is provided on the inner bottom side wall of the lower shell 2, and the limit plate 6 is arranged around the outside of the placement groove 5, wherein the shape of the space enclosed by the limit plate 6 matches the shape of the upper outer wall of the silicone product 12, so that when the PU cloth 13 and the silicone product 12 are pressed together, due to the setting of the limit plate 6 and the limit groove, the silicone product 12 can maintain its own shape when subjected to force without deviating much outward, ensuring the shape of the upper side wall of the silicone product 12, so that the bonding position of the corresponding surface of the lower side wall of the PU cloth 13 and the upper side wall of the silicone product 12 is more accurate; and the upper side wall of the limit plate 6 is lower than the upper side wall of the silicone product 12 installed on the placement groove 5, ensuring that there is a pressure-maintaining space in the vertical direction, and the upper side wall of the silicone product 12 can be in stable contact with the upper side wall of the PU cloth. Furthermore, the inner wall of the limiting plate 6 is in contact with the outer wall of the silicone product 12 located above the placement groove 5. When the silicone product 12 is squeezed, the limiting plate 6 completely limits the shape of the silicone product 12, ensuring that the shape of the upper part of the silicone product 12 does not change, making the bonding position of the corresponding surfaces of the PU cloth 13 and the silicone product 12 more accurate.

[0045] Specifically, a first weight-reducing groove 7 is provided on the upper end surface of the upper shell 1. In order to reduce the weight of the entire upper shell 1, further reduce the weight of the entire jig box, and save materials, and to ensure the strength of the upper shell 1 during use, a plurality of first reinforcing ribs 8 are provided in the first weight-reducing groove 7 to increase the connection strength of the entire upper shell 1. Specifically, in order to further improve the connection strength of the upper shell 1, a plurality of first reinforcing ribs 8 are connected to form a hexagonal structure, so that the plurality of first reinforcing ribs 8 form a whole.

[0046] Specifically, a second weight-reducing groove 9 is provided on the upper end surface of the lower shell 2. In order to reduce the weight of the entire lower shell 2 and further reduce the weight of the entire jig box, and to ensure the strength of the lower shell 2 during use, a plurality of second reinforcing ribs 10 are provided in the second weight-reducing groove 9 to increase the connection strength of the entire lower shell 2. Specifically, in order to further improve the connection strength of the lower shell 2, the plurality of second reinforcing ribs 10 are connected to form a hexagonal structure, so that the plurality of second reinforcing ribs 10 form a whole.

[0047] Specifically, in this embodiment, the snap assembly 3 includes an extension plate 31, a clamping block 32, and a clamping slot 34. One end of the extension plate 31 is located on the outer wall of the lower shell 2, and the other end is connected to the clamping block 32. The clamping block 32 has a clamping portion 33, and the clamping slot 34 is located in the upper shell 1, so that the clamping portion 33 is located in the clamping slot 34, so that the upper shell 1 and the lower shell 2 are buckled together. Moreover, the extension plate 31 and the clamping block 32 are both made of plastic material and have a certain elasticity. The characteristics of the plastic material make the snap assembly 3 composed of the extension plate 31 and the clamping block 32 have a certain elasticity, which is easy to disassemble. Of course, the snap assembly 3 is not limited to this structural form. For example, the snap structure on the backpack strap can also be used, and other snaps in the prior art are also suitable. Of course, in this embodiment, there are four snap assemblies 3, two in a group, and the two groups are respectively located at the two opposite ends of the tool box.

[0048] Specifically, one of the inner bottom side walls of the upper shell 1 or the lower bottom side walls of the lower shell 2 is provided with a positioning column 11, and the other is provided with a positioning groove 101 that cooperates with the positioning column 11. In this embodiment, the inner bottom side wall of the lower shell 2 is provided with a positioning column 11, and there are multiple positioning columns 11. The upper shell 1 is provided with a positioning groove 101, and there are multiple positioning grooves 101, which correspond one to one. When installing the upper shell 1 on the lower shell 2, it is only necessary to align the positioning groove 101 in the upper shell 1 with the positioning column 11 on the lower shell 2 to ensure the subsequent bonding effect of the corresponding surfaces of the two and the accuracy of the bonding position.

[0049] Specifically, the upper shell 1, the lower shell 2, the buckle assembly 3 and the positioning column 11 are all made of plastic materials. It can be seen from the above that all components in the upper shell 1 and the lower shell 2 can be made of plastic materials, and the characteristics of the plastic material make the buckle assembly 3 elastic, easy to disassemble, and easy to snap together the upper shell 1 and the lower shell 2, and the pressure maintaining effect is better, and the cost is low. If damaged, it can be quickly replaced with a new one, and it has strong replaceability.
