Description

Technical Field

[0001] This invention relates to the field of mold bonding, and more specifically to an automatic glue application and bonding device and a glue application and bonding method. Background Technology

[0002] The gearbox housing requires two molds, A and B, to be formed during manufacturing before assembly and bonding. Adhesive is applied to the molding surfaces of both molds to firmly bond them together. After adhesive application, a uniform barrier is formed on the outside of the gearbox housing, effectively preventing oil leakage from the gearbox and ensuring its sealing and durability, thus improving its performance and lifespan. However, existing molding and adhesive application devices face significant challenges in the molding and bonding process. They cannot effectively address dead corners on the molding surfaces, leading to quality issues at the bonding seams, such as cracking of the raw rubber lines and resulting in casting cracks. This results in a high scrap rate for the molds and low bonding efficiency. Furthermore, the adhesive application process involves a large amount of adhesive, leading to high production costs and compromising product quality.

[0003] Chinese patent CN115722415A, entitled "An Automatic Adhesive Application Device," describes an automatic adhesive application device that uses an adhesive homogenization section to evenly distribute the adhesive. The homogenized adhesive is then applied to the profile in the adhesive application section to ensure a uniform distribution of the adhesive on the profile surface and thus guarantee the adhesive application effect. However, this adhesive application device cannot control the amount of adhesive applied to the edges of the profile and the bonding gaps, resulting in poor bonding quality at the edges or bonding surfaces, low casting qualification rate, and it is not suitable for bonding complex surfaces. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of existing mold gluing devices, such as inability to effectively handle dead corners on the parting surface, low bonding efficiency, large amount of glue applied, high production cost, inability to control the amount of glue applied at the edges of profiles and bonding gaps, and inability to be applied to bonding complex surfaces. Therefore, this invention proposes an automatic gluing and bonding device and a gluing and bonding method.

[0005] To achieve the above objectives, the technical solution proposed by this invention is as follows:

[0006] An automatic adhesive application and bonding device is used for bonding the parting surfaces of an external upper mold structure and a lower mold structure. It includes a drive assembly, a lower mold lifting assembly and a molten adhesive tank arranged on the same horizontal line. An upper mold track is arranged horizontally above the two. A glue plate lifting assembly is arranged in the molten adhesive tank. Its special feature is that it also includes an upper conforming assembly, a lower conforming assembly and a glue plate assembly.

[0007] The drive assembly is used to control the upper conforming assembly to slide along the upper mold track to above the lower mold lifting assembly or above the rubber plate lifting assembly;

[0008] The upper conforming component includes an upper mounting plate that is slidably connected to the upper mold track. The lower surface of the upper mounting plate is provided with an upper conforming skeleton structure for mounting the external upper mold structure. Upper positioning bosses are provided at the four corners of the lower surface of the upper mounting plate, and a positioning hole is provided in the middle of each upper positioning boss.

[0009] The lower conforming component includes a lower mounting plate installed on the lower mold lifting component. The upper surface of the lower mounting plate is provided with a lower conforming skeleton structure for installing the external lower mold structure. The lower mounting plate is provided with a lower positioning boss at a position corresponding to the four upper positioning bosses. The top of each lower positioning boss is provided with a positioning post that matches the positioning hole. The corresponding positioning posts and positioning holes cooperate with each other to achieve precise positioning of the upper conforming component and the lower conforming component in the horizontal and vertical directions, thereby improving the bonding quality.

[0010] The adhesive plate assembly includes a mounting plate installed on the adhesive plate lifting assembly. The upper surface of the mounting plate is provided with a three-dimensional adhesive plate that is adapted to the parting surface of the external upper mold structure. An adhesive storage groove is provided on the three-dimensional adhesive plate at a position corresponding to the outer edge of the parting surface, for adhering hot melt adhesive to the parting surface. Adhesive plate positioning bosses are provided on the mounting plate at positions corresponding to the four upper positioning bosses. Each adhesive plate positioning boss has an adjustable guide post at its top that is adapted to the positioning hole, for controlling the contact height and adhesive application amount between the parting surface of the external upper mold structure and the three-dimensional adhesive plate.

[0011] Furthermore, the upper conforming frame structure includes two upper end face clamps and two upper conforming pressure plates. The two upper end face clamps are arranged opposite each other on one set of opposite sides of the lower surface of the upper mounting plate for clamping the external upper mold structure. The two upper conforming pressure plates are respectively arranged on the other set of opposite sides of the lower surface of the upper mounting plate for fixing the external upper mold structure. The two upper end face clamps and the two upper conforming pressure plates form an upper cavity. An upper conforming frame adapted to the external upper mold structure is provided in the upper cavity. The external upper mold structure is embedded in the upper cavity and adapted to the upper conforming frame. The parting surface of the external upper mold structure is located at the lower end and extends beyond the lower end of the two upper end face clamps.

[0012] Furthermore, the lower conforming frame structure includes two lower end face clamps and two lower conforming pressure plates. The two lower end face clamps are arranged opposite each other on one set of opposite sides of the upper surface of the lower mounting plate for clamping the external lower mold structure. The two lower conforming pressure plates are respectively arranged on the other set of opposite sides of the upper surface of the lower mounting plate for fixing the external lower mold structure. The two lower end face clamps and the two lower conforming pressure plates form a lower cavity. A lower conforming frame adapted to the external lower mold structure is provided in the lower cavity. The external lower mold structure is embedded in the lower cavity and adapted to the lower conforming frame. The parting surface of the external lower mold structure is located at the upper end and extends beyond the upper end of the two lower end face clamps.

[0013] Furthermore, the depth of the adhesive storage tank is 1 mm to 3 mm.

[0014] Furthermore, one end of each of the two upper end face clamps is connected to the lower surface of the upper mounting plate via a hinge assembly. When the two upper end face clamps are opened outward via the hinge assembly, the external upper mold structure can be detached. When the two upper end face clamps are closed inward via the hinge assembly, the external upper mold structure can be clamped.

[0015] Furthermore, one end of each of the two lower end face clamps is connected to the upper surface of the lower mounting plate via a hinge assembly. When the two lower end face clamps are opened outward via the hinge assembly, the external lower mold structure can be disengaged. When the two lower end face clamps are closed inward via the hinge assembly, the external lower mold structure can be clamped.

[0016] Furthermore, each of the adjustable guide posts is threadedly connected to the top of the rubber plate positioning boss. By adjusting the threaded connection between the adjustable guide post and the top of the rubber plate positioning boss, the contact height and amount of adhesive between the parting surface of the outer upper mold structure and the three-dimensional rubber plate can be adjusted.

[0017] Furthermore, each of the positioning posts is an adjustable positioning post, and each adjustable positioning post is threadedly connected to the top of each of the lower positioning bosses. By adjusting the threaded connection relationship between the adjustable positioning post and the top of the positioning boss, the mold closing state between the parting surface of the outer upper mold structure and the parting surface of the outer lower mold structure can be controlled.

[0018] Furthermore, the inner surfaces of the two upper end face clamps and the two upper conforming pressure plates are all in contact with the outer upper mold structure;

[0019] The inner surfaces of the two lower end face clamps and the two lower conforming pressure plates are all in contact with the external lower mold structure.

[0020] The present invention also proposes an automatic adhesive application and bonding method, which uses the aforementioned automatic adhesive application and bonding device, and is characterized by including the following steps:

[0021] S1. Embed the external upper mold structure in the upper conforming component, and embed the external lower mold structure in the lower conforming component. Adjust the adjustable guide post on the glue plate component according to the required contact height and glue application amount between the parting surface of the external upper mold structure and the three-dimensional glue plate.

[0022] S2. Start the drive assembly. The drive assembly drives the upper mounting plate of the upper conforming assembly to slide along the upper mold track to the top of the sol pool, and at the same time, the positions of the four adjustable guide posts correspond one by one with the positions of the four positioning holes.

[0023] S3. The three-dimensional glue plate of the glue plate assembly is driven to rise by the glue plate lifting assembly in the glue pool until the upper surface of the three-dimensional glue plate is in contact with the parting surface of the outer upper mold structure, so that a certain amount of hot melt glue is evenly applied to the parting surface of the outer upper mold structure, and the glue plate lifting assembly drives the three-dimensional glue plate to fall.

[0024] S4. The drive component drives the upper mounting plate of the upper conforming component to slide along the upper mold track to the top of the lower conforming component, while making the positions of the four positioning posts correspond one-to-one with the positions of the four positioning holes.

[0025] S5. The lower mold lifting assembly drives the lower mold-following assembly to rise until the parting surface of the outer lower mold structure fits into the parting surface of the outer upper mold structure, thereby completing the mold bonding between the outer upper mold structure and the outer lower mold structure.

[0026] The beneficial effects of this invention are:

[0027] [1] The automatic adhesive bonding device of the present invention, through the rational design of the upper conforming component, the lower conforming component and the adhesive plate component, enables the outer upper mold structure and the outer lower mold structure to achieve precise and efficient bonding, effectively improving the bonding efficiency and bonding quality between the outer upper mold structure and the outer lower mold structure. At the same time, it can also ensure that a certain amount of hot melt adhesive is quickly and evenly bonded at different positions of different height parting surfaces, ensuring the bonding quality of the bonding seam between the outer upper mold structure and the outer lower mold structure, and greatly improving the mold assembly yield.

[0028] [2] By setting a glue storage groove at the edge of the three-dimensional glue plate, the edge of the parting surface of the outer upper mold structure can be immersed in 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 outer upper mold structure and the outer lower mold structure. The middle part of the three-dimensional glue plate is matched with the parting surface of the outer upper mold structure, which can effectively avoid the excessive hot melt glue remaining in the central area of ​​the parting surface, causing glue lines between the outer upper mold structure and the outer lower mold structure. This makes the bonding seam and glue line area between the outer upper mold structure and the outer lower mold structure more compact, effectively reducing the risk of crack defects in the parting surface area, improving the casting qualification rate, and reducing casting costs.

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

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

[0031] [5] The automatic adhesive application and bonding method of the present invention is simple to operate and easy to implement. It can effectively control the amount of adhesive applied to the parting surface of the outer upper mold structure, ensure the bonding quality between the outer upper mold structure and the outer lower mold structure, and improve the bonding qualification rate and bonding efficiency of the product.

Detailed Implementation

[0041] like Figure 1 and Figure 2 As shown, an automatic adhesive bonding device is used for bonding the parting surfaces of an external upper mold structure and a lower mold structure. It includes a drive assembly, a lower mold lifting assembly 4 and a molten adhesive pool 5 arranged on the same horizontal line, an upper mold track 7 horizontally arranged above the lower mold lifting assembly 4 and the molten adhesive pool 5, and a glue plate lifting assembly 6 arranged in the molten adhesive pool 5. It also includes an upper conforming assembly 1, a lower conforming assembly 2 and a glue plate assembly 3. The drive assembly is used to drive and control the upper conforming assembly 1 to slide along the upper mold track 7 to above the lower mold lifting assembly 4 or above the glue plate lifting assembly 6.

[0042] like Figure 3 As shown, the upper conforming component 1 includes an upper mounting plate 8 slidably connected to the upper mold track 7. The lower surface of the upper mounting plate 8 is provided with an upper conforming skeleton structure for mounting the external upper mold structure. The upper conforming skeleton structure includes two upper end face clamping plates 19 and two upper conforming pressure plates 20. One end of each of the two upper end face clamping plates 19 is connected to the lower surface of the upper mounting plate 8 via a hinge assembly. When the two upper end face clamping plates 19 are opened outwards via the hinge assembly, the external upper mold structure can be detached. When the two upper end face clamping plates 19 are closed inwards via the hinge assembly, the external upper mold structure can be clamped. The two upper conforming pressure plates 20 are located on another set of opposite sides on the lower surface of the upper mounting plate 8 for fixing the external upper mold structure. The inner surfaces of plate 19 and the two upper conforming pressure plates 20 are adapted and fitted to the external upper mold structure; the two upper end face clamping plates 19 and the two upper conforming pressure plates 20 form an upper cavity, and an upper conforming skeleton adapted to the external upper mold structure is provided in the upper cavity. The external upper mold structure is embedded in the upper cavity and adapted to the upper conforming skeleton. The parting surface of the external upper mold structure is located at the lower end and extends beyond the lower end of the two upper end face clamping plates 19; upper positioning bosses 9 are provided at the four corners of the lower surface of the upper mounting plate 8. A positioning hole 10 is opened in the middle of each upper positioning boss 9. The corresponding positioning posts 13 and positioning holes 10 cooperate with each other to achieve precise positioning of the upper conforming component 1 and the lower conforming component 2 in the horizontal and vertical directions, thereby improving the bonding quality;

[0043] like Figure 4As shown, the lower conforming assembly 2 includes a lower mounting plate 11 mounted on the lower mold lifting assembly 4. The upper surface of the lower mounting plate 11 is provided with a lower conforming skeleton structure for mounting the external lower mold structure. The lower conforming skeleton structure includes two lower end face clamping plates 21 and two lower conforming pressure plates 22. One end of each of the two lower end face clamping plates 21 is connected to the upper surface of the lower mounting plate 11 via a hinge assembly. When the two lower end face clamping plates 21 are opened outwards via the hinge assembly, the external lower mold structure can be detached. The two lower end face clamping plates 21 are... When the hinged assembly is fused inward, the external lower mold structure can be clamped; two lower conforming pressure plates 22 are set on the other two opposite sides on the upper surface of the lower mounting plate 11 to fix the external lower mold structure; two lower end face clamping plates 21 and two lower conforming pressure plates 22 form a lower cavity, and a lower conforming skeleton adapted to the external lower mold structure is provided in the lower cavity. The external lower mold structure is embedded in the lower cavity and adapted to the lower conforming skeleton. The parting surface of the external lower mold structure is located at the lower end and extends beyond the upper end of the two lower end face clamping plates 21.

[0044] Lower positioning bosses 12 are provided at positions corresponding to the four upper positioning bosses 9 on the lower mounting plate 11. Each lower positioning boss 12 has a positioning post 13 adapted to the positioning hole 10 at its top. Each positioning post 13 is an adjustable positioning post, and each adjustable positioning post is threadedly connected to the top of each lower positioning boss 12. By adjusting the threaded connection between the adjustable positioning post and the top of the positioning boss, the mold closing state between the parting surface of the external upper mold structure and the parting surface of the external lower mold structure can be controlled. This effectively controls the clamping force between the external upper mold structure and the external lower mold structure, ensuring a perfect fit between them and avoiding problems such as loose bonding or structural deformation. This ensures the integrity of the appearance of the assembled product model and improves the bonding qualification rate. The inner surfaces of the two lower end face clamping plates 21 and the two lower conforming pressure plates 22 are adapted to fit the external lower mold structure.

[0045] like Figure 5As shown, the adhesive plate assembly 3 includes a mounting plate 14 installed on the adhesive plate lifting assembly 6. The upper surface of the mounting plate 14 is provided with a three-dimensional adhesive plate 15 adapted to the parting surface of the external upper mold structure. Considering the liquid flow characteristics of hot melt adhesive and the requirements of the model bonding seams, a glue storage groove 16 is provided on the three-dimensional adhesive plate 15 at a position corresponding to the outer edge of the parting surface. This groove allows the hot melt adhesive in the melt pool 5 to adhere to the side surface at the edge of the parting surface. The depth of the glue storage groove 16 is 1mm to 3mm, ensuring that the hot melt adhesive is evenly adhered to a 1-2mm area on the side surface of the model parting surface. Excessive glue will not remain in the central area of ​​the parting surface, preventing a large amount of hot melt adhesive from being squeezed out during mold assembly and bonding, forming a large and high glue line, and causing waste of hot melt adhesive. The working surfaces of the three-dimensional adhesive plate 15 at different heights form mating surfaces with multiple planes of different heights on the parting surface of the external upper mold structure, enabling rapid and automatic parting surface preparation of the external upper mold structure. Uniform adhesive application; Each of the four upper positioning bosses 9 on the mounting plate 14 is provided with a rubber plate positioning boss 17. Each rubber plate positioning boss 17 has an adjustable guide post 18 at its top that matches the positioning hole 10. Each adjustable guide post 18 is threadedly connected to the top of the rubber plate positioning boss 17. By adjusting the threaded connection between the adjustable guide post 18 and the top of the rubber plate positioning boss 17, the contact height and amount of adhesive between the parting surface of the external upper mold structure and the three-dimensional rubber plate 15 can be adjusted. In other words, the contact time and distance between the parting surface and the three-dimensional rubber plate 15 can be controlled by the structure of the three-dimensional rubber plate 15 at different parting surfaces and each parting surface and its side, so as to achieve three-dimensional and uniform application of hot melt adhesive on the parting surface, reducing the risk of defects in the mold seam area; at the same time, it can achieve precise positioning of the upper conformal component 1 and the rubber plate component 3 in the horizontal and vertical directions.

[0046] The present invention also proposes an automatic adhesive application and bonding method, which uses the above-mentioned automatic adhesive application and bonding device and includes the following steps:

[0047] S1. Embed the external upper mold structure in the upper conforming component 1, and embed the external lower mold structure in the lower conforming component 2. Adjust the adjustable guide post 18 on the glue plate component 3 according to the required contact height and glue application amount between the parting surface of the external upper mold structure and the three-dimensional glue plate 15.

[0048] S2. Start the drive assembly. The drive assembly drives the upper mounting plate 8 of the upper conforming assembly 1 to slide along the upper mold track 7 to the top of the sol pool 5, and at the same time makes the positions of the four adjustable guide pillars 18 correspond one by one with the positions of the four positioning holes 10.

[0049] S3, such as Figure 7As shown, the glue plate lifting assembly 6 in the glue pool 5 drives the three-dimensional glue plate 15 of the glue plate assembly 3 to rise until the upper surface of the three-dimensional glue plate 15 is in contact with the parting surface of the outer upper mold structure, so that a certain amount of hot melt glue is evenly applied to the parting surface of the outer upper mold structure, and the glue plate lifting assembly 6 drives the three-dimensional glue plate 15 to fall.

[0050] S4. The drive component drives the upper mounting plate 8 of the upper conforming component 1 to slide along the upper mold track 7 to the top of the lower conforming component 2, while making the positions of the four positioning pins 13 correspond one by one with the positions of the four positioning holes 10.

[0051] S5, such as Figure 6 As shown, the lower mold lifting component 4 drives the lower mold conforming component 2 to rise until the parting surface of the outer lower mold structure is in contact with the parting surface of the outer upper mold structure, and stabilizes for 10s to 20s, thereby completing the mold bonding between the outer upper mold structure and the outer lower mold structure.

[0052] S6. Open the two upper end face plates 19 of the upper conforming skeleton structure and the two lower end face plates 21 of the lower conforming skeleton structure respectively to complete the demolding and obtain a product model that is bonded into a whole.

The drive assembly drives the upper mounting plate (8) of the upper conforming assembly (1) to slide along the upper mold track (7) to the top of the lower conforming assembly (2), while making the positions of the four positioning pins (13) correspond one-to-one with the positions of the four positioning holes (10); S5. The lower mold lifting assembly (4) drives the lower mold conforming assembly (2) to rise until the parting surface of the outer lower mold structure fits with the parting surface of the outer upper mold structure, thereby completing the mold bonding between the outer upper mold structure and the outer lower mold structure.
