Description

Technical Field

[0001] The utility model relates to the technology of structural member bonding, in particular to a bonding and pressure-holding device capable of accelerating drying. Background Art

[0002] In the process of bonding structural members, it is usually necessary to achieve a tightly fitting state between the structural members so that the bonding ability of the adhesive can be best exerted. Therefore, in industrial production, the bonding of structural members usually requires a pressurizing process and the pressure needs to be maintained before the adhesive cures and becomes effective. Obviously, the curing speed of the adhesive is directly related to the efficiency of the structural member bonding process.

[0003] The applicant has found in practice that the curing speed of the adhesive is usually proportional to the temperature, and it is necessary to conduct research and development on the technical direction of accelerating the curing of the adhesive in the structural member bonding process. Summary of the Utility Model

[0004] The utility model aims to provide a bonding and pressure-holding device capable of accelerating drying, which shortens the bonding and pressure-holding duration by accelerating the drying of the adhesive, thereby significantly improving the production efficiency of the structural member bonding process and enhancing the bonding effect of the structural members at the same time.

[0005] To achieve the above object, the utility model adopts the following technical solutions.

[0006] The bonding and pressure-holding device capable of accelerating drying includes a machine table and a pressure-holding mechanism arranged on the machine table; the pressure-holding mechanism includes a base for supporting the structural members to be bonded, a pressure plate arranged above the base, and an execution unit for driving the pressure plate to open and close relative to the base;

[0007] It further includes a hot air blower arranged in the machine table, and the hot air blower has an air duct for outputting hot air to the outside;

[0008] The top of the base of the pressure-holding mechanism is provided with a gas guide plate, the top surface of the gas guide plate has gas guide grooves in a grid shape, the bottom surface of the gas guide plate has an air inlet pipe leading to the gas guide grooves, and the gas guide grooves are connected to the air duct through the air inlet pipe;

[0009] After the gas guide plate and the pressure plate are closed, they cooperate to clamp the structural members to be bonded, and an air gap for exhausting the gas guide grooves is formed between the top surface of the gas guide plate and the outer surface of the structural members to be bonded.

[0010] Preferably, the execution unit is a cylinder.

[0011] Furthermore, the pressure-holding mechanism further includes a regulator for adjusting the pressure and stroke time of the cylinder.

[0012] As an improvement of the above technical solution, the top surface of the air guide plate has protruding support ribs. After the air guide plate and the pressure plate are closed, a mating gap for accommodating the structure to be bonded is formed by the support of the support ribs.

[0013] Furthermore, the support ribs divide the top surface of the air guide plate into at least two spaced heating zones, and a set of air guide grooves are respectively arranged in each heating zone.

[0014] As another improvement of the above technical solution, there are multiple juxtaposed pressure maintaining mechanisms, and the air inlet pipes of the air guide plates in each pressure maintaining mechanism are respectively connected in parallel to the hot air blower through air ducts.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The hot air output by the hot air blower is sent to the air guide grooves of the air guide plate through the air duct, directly allowing the hot air to quickly contact the structure to be bonded, so that the adhesive applied to the structure to be bonded is quickly dried and cured, thereby shortening the pressure maintaining time of the pressure maintaining mechanism and achieving rapid bonding, which can effectively improve the efficiency of the bonding process of the structure.

[0017] Next, the utility model will be further described in conjunction with the accompanying drawings of the specification and the specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 is a schematic diagram of the working state of the utility model.

[0020] Figure 3 is an embodiment of the air guide plate in the utility model.

[0021] Figure 4 is another embodiment of the air guide plate in the utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figure 1 and Figure 2 shown, the utility model provides an adhesive pressure maintaining device capable of accelerating drying, including a machine table 1 and a pressure maintaining mechanism 2 arranged on the machine table 1; the pressure maintaining mechanism 2 includes a base 3 for supporting the structure to be bonded, a pressure plate 4 arranged above the base 3, and an execution unit 5 for driving the pressure plate 4 to open and close relative to the base 3;

[0023] It further includes a hot air blower 6 arranged in the machine table 1, and the hot air blower 6 has an air duct 61 for outputting hot air externally;

[0024] On the top of the base 3 of the pressure-holding mechanism 2, there is an air guide plate 31. The top surface of the air guide plate 31 has air guide grooves 32 in a grid pattern. The bottom surface of the air guide plate 31 has an air inlet pipe 33 that penetrates through to the air guide grooves 32. The air guide grooves 32 are connected to the air duct 61 through the air inlet pipe 33;

[0025] After the air guide plate 31 and the pressure plate 4 are closed, they cooperate with each other to clamp the structure to be bonded. An air gap for the air guide grooves 32 to exhaust air is formed between the top surface of the air guide plate 31 and the outer surface of the structure to be bonded.

[0026] In the present utility model, the hot air blower 6 can be adapted to known existing machine models. The hot air blower used by the applicant during the production debugging stage is a 3000W portable industrial hot air blower sold by Dongguan Yuqi Electromechanical Equipment Accessories Co., Ltd. The heating effect and heating efficiency have both reached the design expectations. Tests show that the adhesive applied with glue at the midpoint of the structure to be bonded 91 is quickly dried and cured.

[0027] The basic principle of the present utility model is as follows:

[0028] After the adhesive is dispensed and distributed on the structure to be bonded 91, the structure to be bonded 91 is placed on the air guide plate 31 of the base 3. The execution unit 5 drives the pressure plate 4 so that the air guide plate 31 and the pressure plate 4 are closed. After the air guide plate 31 and the pressure plate 4 are closed, they cooperate with each other to clamp the structure to be bonded 91, that is, to perform pressure holding on the structure to be bonded 91;

[0029] Then, the hot air output by the hot air blower 6 is sent to the air guide grooves 32 of the air guide plate 31 through the air duct 61, directly allowing the hot air to quickly contact the structure to be bonded 91.

[0030] Obviously, the present utility model enables the adhesive applied with glue at the midpoint of the structure to be bonded 91 to be quickly dried and cured, thereby shortening the pressure-holding time of the pressure-holding mechanism 2 and achieving rapid bonding, and can effectively improve the efficiency of the bonding process of the structural members.

[0031] In a preferred embodiment, the execution unit 5 is a cylinder.

[0032] Furthermore, the pressure-holding mechanism 2 further includes a regulator 21 for adjusting the pressure and stroke time of the cylinder, controlling the pressure and time output by the cylinder, and better realizing the desired pressure-holding effect. In the present utility model, the regulator 21 can be adapted to known existing machine models. The regulator used by the applicant during the production debugging stage is an air regulator with the model BF-4000.

[0033] In another preferred embodiment, there are multiple pressure-holding mechanisms 2 arranged side by side. The air inlet pipes 33 of the air guide plates 31 in each pressure-holding mechanism 2 are respectively connected in parallel to the hot air blower 6 through the air ducts 61. This embodiment better meets the needs of batch production and can also enable the hot air blower 6 to obtain better output efficiency.

[0034] As Figure 3 shown, in one embodiment, the top surface of the air guide plate 31 has protruding support ribs 311. After the air guide plate 31 and the pressure plate 4 are closed, a fitting gap for accommodating the structure to be bonded is formed by the support of the support ribs 311.

[0035] Obviously, in Figure 3 the embodiment shown, the single structure 92 to be bonded is directly clamped between the pressure plate 4 and the air guide plate 31, so that effective pressure holding can be obtained, and at the same time, the curing of the adhesive therein can be significantly accelerated.

[0036] As Figure 4 shown, in another embodiment, the top surface of the air guide plate 31 has protruding support ribs 312. The support ribs 312 divide the top surface of the air guide plate 31 into at least two spaced heating zones 310, and a set of air guide grooves 32 are respectively arranged in each heating zone 310. At the same time, after the air guide plate 31 and the pressure plate 4 are closed, a fitting gap for accommodating the structure to be bonded is formed by the support of the support ribs 312.

[0037] Obviously, in Figure 4 the embodiment shown, a structure 93 to be bonded can be placed in each heating zone 310 respectively, so that effective pressure holding can be carried out on multiple structures to be bonded simultaneously, and at the same time, the curing of the adhesive therein can be significantly accelerated.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
