Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glue dispensing jigs, in particular to a pneumatic pressure-maintaining jig. Background Art
[0002] Glue dispensing is a common process, especially in the process of manufacturing small workpieces. Simply put, it is to bond two structural parts by applying glue between them. For example, in the new energy vehicle connection component CCS (Cells Contact System), the connection method of aluminum parts and plastic parts. In the production process, the glue dispensing process is often used to tightly bond aluminum parts to plastic parts with glue. Since the sticky glue layer has a certain thickness, the workpiece needs to be pressed after glue dispensing so that the two structural parts are as close as possible. Conventional technology requires that the aluminum part be pressed tightly against the plastic part manually to ensure that the bottom surface of the aluminum part placed on the glue can be in full contact with the glue, and the glue is flattened so that it can be in close contact with the plastic part, thereby increasing the bonding area between the aluminum part and the plastic part and improving the bonding strength. However, the above method has an obvious flaw: manual operation cannot guarantee that the pressure applied to the aluminum parts is the same each time, which can easily lead to two problems: 1. After the pressure is applied, some parts are prone to glue overflow, which will increase the subsequent workload and reduce the thickness of the glue layer between the aluminum parts and the plastic parts, resulting in a decrease in the strength of the aluminum parts and plastic parts after bonding; 2. Since extrusion cannot guarantee that the force used for each pressing is the same, the thickness of the product will be different after the aluminum parts are bonded to the plastic parts, and the product quality cannot be guaranteed. Utility Model Content

[0004] In order to solve the above technical problems, a technical solution adopted by the utility model is: a pneumatic pressure-maintaining fixture, comprising: a tray structure for placing plastic parts and aluminum parts, and an outer frame structure for applying a pressing force to the plastic parts on the tray structure.
[0005] Preferably, the pallet structure comprises an upper pallet plate and a lower pallet plate, and the upper pallet plate and the lower pallet plate are connected via a pallet support frame that plays a supporting role.

[0014] The beneficial effects of the utility model are:
[0015] The utility model discloses a pneumatic pressure-maintaining fixture with a simple structure and convenient use. By cooperating the tray structure with the outer frame structure, uniform contact of glue and uniform pressing force between aluminum parts and plastic parts are achieved. The plastic parts and aluminum parts are placed on an upper plate of the tray structure and enter the outer frame structure after glue dispensing.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0022] Example:
[0023] This embodiment introduces the structure of a pneumatic pressure-maintaining fixture.
[0024] Combined with Figure 1 As shown, Figure 1 The pneumatic pressure-maintaining fixture of the utility model is a structural schematic diagram. The pneumatic pressure-maintaining fixture comprises: a tray structure for placing plastic parts and aluminum parts, and an outer frame structure for applying a pressing force to the plastic parts on the tray structure.
[0025] Combined with Figure 2 , 3 As shown, Figure 2 This is a schematic diagram of the decomposition of the pneumatic pressure-maintaining fixture. Figure 3 2 is a schematic diagram of the structure of the pneumatic pressure-maintaining fixture from another angle. The pallet structure comprises a pallet upper plate 3 and a pallet lower plate 6, and the pallet upper plate 3 and the pallet lower plate 6 are connected by a pallet support frame 4 that plays a supporting role.
[0026] The outer frame structure includes an upper cover plate 1 and a lower cover plate 11 . The upper cover plate 1 and the lower cover plate 11 form a semi-enclosed structure through a side cover plate 5 .
[0027] Furthermore, a rubber pad 2 is provided under the upper cover plate 1. The function of the rubber pad is to assist the aluminum parts and the plastic parts to be pressed evenly when the product is pressurized after dispensing, so as to avoid damage to the product due to uneven pressure.
[0028] Furthermore, the outer frame structure includes a rear limit plate 7, a rear limit pin 8, and a side limit plate 9; the rear limit plate 7 and the rear limit pin 8 are arranged at the rear end of the lower cover plate 11; and the side limit plate 9 is arranged on the lower cover plate 11. The rear limit plate 7, the rear limit pin 8, and the side limit plate 9 facilitate the relative limit fixing of the position where the plastic parts and aluminum parts driven by the pallet structure enter the outer frame structure, so as to prevent the pallet structure from entering the outer frame structure in an improper position, for example, extending out of the outer frame structure, so that when the pressing force is applied, the plastic parts and aluminum parts on the upper plate of the pallet cannot be fully aligned and pressurized.
[0029] Wherein, a plurality of the side limiting plates 9 can be arranged at intervals on the lower cover plate 11 , and the interval distribution can better support and slide the tray structure.
[0030] Furthermore, the outer frame structure also includes a cylinder 10 , and the cylinder 10 is disposed on the lower cover plate 11 .
[0031] Among them, the cylinders 10 can be arranged in multiple intervals on the lower cover plate 11 and located between the side limit plates 9. By arranging multiple cylinders at different positions of the lower cover plate, it is better to apply uniform pressing force to the aluminum parts and plastic parts of the upper plate of the pallet when the cylinders are used.
[0032] By using the pneumatic pressure-maintaining fixture formed by the above structure, during use, the pallet structure can be directly used to place plastic parts, and the glue dispenser completes the glue dispensing on the plastic parts on the pallet structure, and then the aluminum parts are placed on the plastic parts. Be careful not to touch the aluminum parts forcefully during this process; then, the pallet structure is sent into the outer frame structure along the guide rail, and the rear limit plate and the side limit plate will fix the relative position of the pallet structure; further, turn on the cylinder switch, the guide column of the cylinder will contact the lower plate of the pallet, and push the entire pallet structure upward and close to the rubber pad, so that the aluminum parts are evenly pressed downward toward the plastic parts. After the compaction is completed, turn off the air pump switch, pull out the pallet, remove the pressed product, and return the pallet to the glue dispenser.
[0033] By using the pneumatic pressure-maintaining fixture, the pressure applied to aluminum parts and plastic parts during the dispensing process can be uniform and stable, ensuring the consistency of product quality and improving production efficiency.
[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
