[0002] Automatic glue application equipment is used to replace manual glue application and is widely used in many industries, such as automobile manufacturing, electronic information, medical device and footwear manufacturing. However, existing automatic glue application equipment may experience glue breakage or low surface cleanliness during the glue application process, which reduces the glue adhesion effect. It also cannot perform surface cleaning and glue application processes at the same time, resulting in low work efficiency. Therefore, we designed an automatic glue application device that can apply glue evenly.

[0003] Chinese utility model patent CN202223265162.7 discloses an automatic glue applicator comprising a base; a robotic arm mounted on the base, the robotic arm having an end effector point; a paint bucket mounted on the end effector point; a forward positioning mechanism fixed on the base; and a rotating platform mounted on the forward positioning mechanism; wherein the robotic arm drives the paint bucket to form a coating area for applying adhesive. This utility model's automatic glue applicator achieves automatic and accurate glue application and improves adhesive application efficiency. However, this device has the following problems: firstly, it lacks the ability to simultaneously perform surface cleaning, glue application, and scraping processes, resulting in low efficiency; secondly, during the glue application process, issues such as glue breakage and low surface cleanliness may occur, reducing the adhesive adhesion effect. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by setting cleaning arms, coating structures, blocking plates, adjustment holes and fixing holes in front and behind the coating head. This solves the technical problems of existing automatic glue coating equipment, such as glue breakage and low surface cleanliness during the glue coating process, which reduce the glue adhesion effect and cannot perform surface cleaning and glue coating processes at the same time, resulting in low work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic adhesive applicator for uniform adhesive application includes an adjustment mechanism. An L-shaped mounting plate is located at the front end of the adjustment mechanism. A coating structure is located at the rear lower end of the L-shaped mounting plate. A clamping plate is located at the front end of the L-shaped mounting plate. An adhesive applicator head is located between the clamping plate and the L-shaped mounting plate. A cleaning arm is connected to the front end of the clamping plate. An addition port is located at the front upper end of the cleaning arm. The lower end of the addition port is connected to a liquid storage tank. A step is provided on the lower inner surface of the liquid storage tank.

[0007] As a preferred embodiment, a rectangular groove is provided at the lower front end of the cleaning arm, the upper end of the step abuts against the blocking plate, and the front end of the blocking plate protrudes vertically through the rectangular groove at the front end of the cleaning arm.

[0008] As a preferred embodiment, the cleaning arm has symmetrical connecting holes at the lower sides of both ends. A smooth rod bolt is installed in the connecting hole. The smooth rod part of the smooth rod bolt is sleeved with the cleaning cotton block, and the front end of the smooth rod bolt is threaded with a nut. The lower end of the cleaning cotton block protrudes vertically from the surface of the cleaning arm.

[0009] As a preferred embodiment, the coating structure includes a straight rod, the lower end of which is connected to a trapezoidal platform. The left and right surfaces of the trapezoidal platform are provided with cavities, and the upper surface of the trapezoidal platform is provided with fixing holes symmetrically on the left and right sides.

[0010] As a preferred embodiment, the cavity is provided with symmetrical extension plates on the left and right sides, a set of springs is provided between the extension plates, and adjustment holes are evenly distributed on the upper end of the extension plates, the size of the adjustment holes matching the size of the fixing holes.

[0011] As a preferred embodiment, the positioning mechanism includes a first rail assembly, the front end of the sliding block of the first rail assembly is fixedly connected to a second rail assembly, the front end of the sliding block of the second rail assembly is fixedly connected to a third rail assembly, and the front end of the sliding block of the third rail assembly is fixedly connected to an L-shaped mounting plate.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, a cleaning arm and a coating structure are set in front and behind the glue applicator. Under the drive of the adjustment mechanism, the three work synchronously, so that the cleaning arm cleans the surface on the front side, the glue applicator dispenses glue in the middle, and the coating structure coats the glue evenly on the rear side, thereby speeding up the working speed, ensuring uniform glue application, improving the adhesion effect, and reducing the possibility of glue breakage during glue application.

[0014] (2) In this utility model, by setting a blocking plate and a waterproof rubber pad between the blocking plate and the rectangular groove, the two are tightly connected to prevent the cleaning liquid from overflowing between them. Secondly, a waterproof rubber pad is also provided between the blocking plate and the step, so that when the blocking plate and the step are completely overlapped, the cleaning liquid is blocked and cannot flow downward. The blocking plate plays the role of controlling the flow of the cleaning liquid.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, this utility model provides an automatic glue-applying device for uniform glue application, including an adjusting mechanism 1, which flexibly adjusts the positions of the applicator structure 3, the glue applicator head 5, and the cleaning arm 6. An L-shaped mounting plate 2 is provided at the front end of the adjusting mechanism 1, and the applicator structure 3 is located at the lower rear end of the L-shaped mounting plate 2 to uniformly apply glue to the dispensing position, reducing the possibility of glue dispensing interruption and ensuring adhesion. A clamping plate 4 is provided at the front end of the L-shaped mounting plate 2 to fix the glue applicator head 5. The glue applicator head 5 is located between the clamping plate 4 and the L-shaped mounting plate 2, and its upper end is connected to a glue tank via a pipe, allowing the glue in the glue tank to enter the glue applicator head 5 through the pipe. The adhesive is dispensed evenly, and the front end of the clamping plate 4 is connected to the cleaning arm 6, increasing the distance between the adhesive head 5 and the cleaning cotton block 68, allowing the cleaning liquid time to evaporate and the adhesive surface to dry. The upper front end of the cleaning arm 6 is provided with an inlet 61, which is plugged to prevent the cleaning liquid in the storage tank 62 from evaporating. The lower end of the inlet 61 is connected to the storage tank 62, which contains cleaning liquid, which can be alcohol. The cleaning liquid has a fast evaporation rate, removes dirt and grease from the surface of objects, and improves surface roughness and clarity. The lower inner surface of the storage tank 62 is provided with a step 63, which limits the position of the blocking plate 64.

[0025] Furthermore, such as Figure 2 As shown, a rectangular groove 65 is provided on the lower front end of the cleaning arm 6. The upper end of the step 63 abuts against the blocking plate 64. The front end of the blocking plate 64 passes through the rectangular groove 65 and protrudes vertically at the front end of the cleaning arm 6. A waterproof rubber gasket is provided between the blocking plate 64 and the rectangular groove 65, so that the two are tightly abutted to prevent the cleaning fluid from overflowing from the two. Furthermore, a waterproof rubber gasket is also provided between the blocking plate 64 and the step 63. When the blocking plate 64 and the step 63 are completely overlapped, the cleaning fluid is blocked and cannot flow downward. The blocking plate 64 plays the role of controlling the flow of the cleaning fluid.

[0026] Furthermore, such as Figure 3 As shown, the front and rear ends of the cleaning arm 6 are symmetrically provided with connecting holes 66 on their lower sides. A smooth rod bolt 67 is provided in the hole of the connecting hole 66. The smooth rod part of the smooth rod bolt 67 is sleeved with a cleaning cotton block 68, and the front end of the smooth rod bolt 67 is threaded with a nut 69. The lower end of the cleaning cotton block 68 protrudes vertically from the surface of the cleaning arm 6. The cleaning liquid in the liquid storage tank 62 flows downward, so that the cleaning cotton block 68 is filled with cleaning liquid, wiping the surface and improving the surface cleanliness.

[0027] Furthermore, such as Figure 4 As shown, the coating structure 3 includes a straight rod 31, the lower end of which is connected to a trapezoidal platform 32. The left and right surfaces of the trapezoidal platform 32 are provided with cavities 33 to provide space for installing the extension plate 35. The upper surface of the trapezoidal platform 32 is provided with fixing holes 34 symmetrically on the left and right sides, which are used in conjunction with the adjustment holes 37.

[0028] Furthermore, the cavity 33 is symmetrically provided with extension plates 35 on the left and right sides, and a set of springs 36 is provided between the extension plates 35 to increase the stability between the extension plates 35 and prevent the extension plates 35 from extending too far and shaking. The upper end of the extension plates 35 is evenly distributed with adjustment holes 37. The adjustment holes 37 and the fixing holes 34 are matched in structure and size, and the two are fixedly connected by bolts. By selecting the appropriate position of the adjustment hole 37 and the fixing hole 34 for connection, the application size can be adjusted, thereby improving applicability.

[0029] Furthermore, such as Figure 1 As shown, the adjustment mechanism 1 includes a first track assembly 11, which enables the application structure 3, the glue application head 5, and the cleaning arm 6 to move back and forth. The front end of the sliding block of the first track assembly 11 is fixedly connected to the second track assembly 12, which enables the application structure 3, the glue application head 5, and the cleaning arm 6 to move left and right. The front end of the sliding block of the second track assembly 12 is fixedly connected to the third track assembly 13, which enables the application structure 3, the glue application head 5, and the cleaning arm 6 to move up and down, increasing flexibility. The front end of the sliding block of the third track assembly 13 is fixedly connected to the L-shaped mounting plate 2.

[0030] Working process: First, the positioning mechanism 1 adjusts the positions of the coating structure 3, the glue applicator 5, and the cleaning arm 6 to be positioned above the surface to be coated. Next, the first guide rail assembly 11 operates, causing the coating structure 3, the glue applicator 5, and the cleaning arm 6 to move forward. Then, the cleaning liquid in the storage tank 62 flows downwards, saturating the cleaning cotton pad 68 with the cleaning liquid, wiping the surface and improving its cleanliness. Next, the glue applicator 5 dispenses glue onto the cleaned surface. Finally, the scraper, composed of the extension plate 35 and the trapezoidal platform 32, evenly coats the glued area, reducing the possibility of glue breakage during dispensing and improving work efficiency.
