Description

Technical Field

[0001] The invention relates to the field of mold bonding, and in particular to an automatic gluing bonding device and a gluing bonding method. Background Art

[0002] During the processing of the gearbox housing, it is necessary to form two models of A and B and then assemble the molds and bond them. Glue is applied on the two sets of molding surfaces to firmly bond the two models. After the gluing process is completed, a uniform barrier will be formed on the outside of the gearbox housing, which can effectively prevent the oil leakage inside the gearbox to ensure the sealing and durability of the gearbox and improve the performance and life of the gearbox. However, when the existing mold assembly and gluing device is performing the gluing process, the mold assembly and bonding process is more difficult, and the dead angle positions on the two sets of molding surfaces cannot be effectively processed. The bonding seam is prone to quality problems, causing the raw rubber line to crack and form casting cracks, resulting in a high model scrap rate and low bonding efficiency. In addition, the amount of glue applied during the gluing process is large, the production cost is high, and the product quality cannot be guaranteed.

[0003] Publication number CN115722415A is a Chinese patent for an automatic gluing device. The colloid is evenly distributed through a colloid homogenizing section, and the evenly distributed colloid is then applied to the profile in the gluing section to ensure that the colloid is evenly distributed on the profile surface, thereby ensuring the gluing effect on the profile surface. However, the gluing device cannot control the amount of glue applied at the edge of the profile and the bonding gap, resulting in poor bonding quality at the edge or bonding surface, a low qualified rate of castings, and is not suitable for bonding complex surfaces. Summary of the Invention

[0004] The purpose of the present invention is to solve the technical problems such as the inability of existing mold assembly gluing devices to effectively deal with dead corners on the parting surface, low bonding efficiency, large glue application amount, high production cost, inability to control the glue application amount at the edge of the profile and the bonding gap, and inability to be suitable for bonding complex surfaces, and to propose an automatic gluing and bonding device and a gluing and bonding method.

[0010] The rubber plate assembly includes a mounting plate installed on the rubber plate lifting assembly, and the upper surface of the mounting plate is provided with a three-dimensional rubber plate adapted to the parting surface of the external upper mold structure, and a glue storage groove is provided at a position corresponding to the outer edge of the parting surface on the three-dimensional rubber plate, which is used to allow the hot melt glue to adhere to the parting surface; rubber plate positioning bosses are provided at positions on the mounting plate corresponding to the four upper positioning bosses, and an adjustable guide column adapted to the positioning hole is provided on the top of each rubber plate positioning boss, which is used to control the contact height and glue coating amount between the parting surface of the external upper mold structure and the three-dimensional rubber plate.

[0027] [1] The automatic glue coating and bonding device of the present invention rationally designs the upper follow-up component, the lower follow-up component and the glue plate component, so that the external upper mold structure and the external lower mold structure can be bonded accurately and efficiently, effectively improving the bonding efficiency and bonding quality between the external upper mold structure and the external lower mold structure. At the same time, it can also ensure that a certain amount of hot melt glue is bonded quickly and evenly at different positions of the parting surface at different heights, ensuring the bonding quality of the bonding seam between the external upper mold structure and the external lower mold structure, and greatly improving the mold assembly finished product rate.

[0028] [2] The present invention provides a glue storage groove at the edge of the three-dimensional rubber plate, so that the edge of the parting surface of the external upper mold structure can be immersed in the hot melt glue, so that a certain amount of hot melt glue is bonded to the side of the edge, which greatly improves the bonding quality between the external upper mold structure and the external lower mold structure. The middle part of the three-dimensional rubber plate is adapted to the parting surface of the external upper mold structure, which can effectively avoid excessive hot melt glue remaining in the central area of ​​the parting surface, resulting in a glue line between the external upper mold structure and the external lower mold structure, making the bonding seam and glue line area between the external upper mold structure and the external lower mold structure more tightly bonded, effectively reducing the risk of crack defects in the parting surface area of ​​the two, improving the qualified rate of castings, and reducing casting costs.

[0029] [3] The present invention can achieve precise positioning of the upper and lower follow-up components in the horizontal and vertical directions through corresponding positioning holes and positioning columns, thereby improving the bonding quality. At the same time, it can also effectively control the pressing force between the external upper mold structure and the external lower mold structure, so that the two fit perfectly, avoiding problems such as loose bonding or structural deformation, ensuring the integrity of the appearance of the molded product model, and improving the bonding qualification rate.

[0030] [4] The present invention can achieve precise positioning of the upper mold component and the rubber plate component in the horizontal and vertical directions through the corresponding positioning holes and adjustable guide columns. The adjustable guide columns can effectively control the contact height and glue amount between the parting surface of the external upper mold structure and the three-dimensional rubber plate, and control the amount of hot melt adhesive applied, effectively avoiding the risk of glue dead corners and cracking during the glue application and mold assembly process, effectively improving the bonding efficiency, reducing the bonding area and glue amount, improving product quality, and saving production costs.

[0031] [5] The automatic gluing and bonding method of the present invention has a simple operation process and is easy to implement. It can effectively control the amount of glue applied on the parting surface of the external upper mold structure, ensure the bonding quality between the external upper mold structure and the external lower mold structure, and improve the bonding qualification rate and bonding efficiency of the product.
