Description

Technical Field

[0001] This utility model relates to the field of vehicle logo adhesive production technology, and in particular to an adhesive pressing device. Background Technology

[0002] As a brand identification element, car emblems are typically fixed in a prominent position at the front and rear of vehicles in the form of static metal or plastic badges. Their core functions are brand identification and aesthetic decoration. During the production process, foam adhesive needs to be applied to one side of the emblem. Foam adhesive, also known as foam-based double-sided tape, is a soft adhesive with a flexible foam plastic substrate in the middle layer and double-sided adhesive on both sides. This foam adhesive is used to adhere the car emblem to the vehicle and provides good shock absorption; this process is called emblem application. Currently, the emblem and foam adhesive are applied manually without tools, which easily leads to poor adhesion between the emblem and the adhesive. During the emblem installation process, workers need to peel off the film layer of the foam adhesive away from the emblem, which can easily peel off the foam adhesive as well, causing the emblem to be scrapped, resulting in material waste, low production efficiency, and a high defect rate. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an adhesive bonding device that can improve the adhesion between the car logo and the foam adhesive, increase product processing yield, and improve operational convenience.

[0022] Reference Figures 1 to 4 This utility model embodiment provides an adhesive bonding device, including a base plate 100, a pressure seat 200, and a pressing mechanism 300. The pressure seat 200 is disposed on the upper side of the base plate 100, and a first positioning groove 210 and a positioning pin 230 are provided on the upper side of the pressure seat 200. The positioning pin 230 is disposed inside the first positioning groove 210. The first positioning groove 210 is used to position a car logo 500, and the positioning pin 230 is used to position foam adhesive 600. Specifically, the first positioning groove 210 is formed by a recess in the upper surface of the pressure seat 200, and the first positioning groove 210 matches the outer periphery of the car logo 500. Specifically, the foam adhesive 600 is provided with a positioning hole corresponding to the positioning pin 230. By fitting the positioning hole of the foam adhesive 600 onto the positioning pin 230, the auxiliary positioning of the foam adhesive 600 can be achieved. The pressing mechanism 300 includes a pressing block 310, which is disposed above the pressure seat 200 and can be matched and connected with the pressure seat 200.

[0023] Specifically, the pressure bearing seat 200 is detachably connected to the upper side of the base plate 100. This facilitates the installation, replacement, or removal of the pressure bearing seat 200.

[0024] Preferably, the pressure seat 200 is made of a hard material, such as metal or PVC plastic; the pressure block 310 is made of a softer plastic, such as TPU plastic, which can better transmit downward pressure and is less likely to damage the car logo 500.

[0025] The first positioning groove 210 allows for quick and precise positioning of the outer periphery of the car logo 500. Subsequently, the positioning pin 230 positions the foam adhesive 600, achieving efficient and accurate alignment and placement between the car logo 500 and the foam adhesive 600. This effectively avoids the bonding deviation problems caused by inaccurate positioning in traditional operations. Furthermore, through the cooperation of the pressure block 310 and the pressure seat 200, the pressure block 310 is pressed downwards onto the upper side of the pressure seat 200, ensuring that the car logo 500 and the foam adhesive 600 placed on the pressure seat 200 are evenly compressed, resulting in a firm bond. This pressing process is not only simple to operate but also significantly improves the bonding strength and consistency between the car logo 500 and the foam adhesive 600, thereby effectively improving overall processing efficiency and product quality. Furthermore, the positioning pin 230 is located on the upper side of the pressure seat 200 and inside the first positioning groove 210. This compact layout effectively reduces the overall footprint of the adhesive bonding device, facilitating its placement and storage on the production floor, and is particularly suitable for assembly environments with limited space. This invention significantly improves the adhesion between the car logo 500 and the foam adhesive 600, making it less likely for the foam adhesive 600 to be accidentally torn off by workers during subsequent assembly into the car, greatly reducing cost losses due to rework or scrap, minimizing material waste, and improving product yield. Simultaneously, the adhesive bonding device of this invention features a simple operation process, rapid positioning, and reliable bonding, contributing to further improved production efficiency and making it suitable for large-scale, continuous production needs.

[0026] According to some embodiments of this application, refer to Figure 1 and Figure 3 The pressure-bearing seat 200 is also provided with a second positioning groove 220, which is located inside the first positioning groove 210. The second positioning groove 220 is used to position the car logo 500. Specifically, the first positioning groove 210 is used to position the outer periphery of the car logo 500, and the second positioning groove 220 is used to position the inner structure of the car logo 500. The second positioning groove 220 can further improve the accuracy of positioning the car logo 500.

[0027] Furthermore, referring to Figure 1 and Figure 4 At least two positioning pins 230 are provided, and the at least two positioning pins 230 are spaced apart. The foam adhesive 600 is provided with at least two positioning holes corresponding to the positioning pins 230. The spaced arrangement of at least two positioning pins 230 can improve the accuracy of positioning the foam adhesive 600.

[0028] According to some embodiments of this application, refer to Figure 2The pressure block 310 has a protrusion 311 on its lower side. Specifically, the protrusion 311 is matched with the car logo 500 and the foam adhesive 600 placed on the pressure seat 200. When the pressure block 310 is pressed and connected to the pressure seat 200, the protrusion 311 can press down on the top of the foam adhesive 600, thereby pressing the foam adhesive 600 onto the car logo 500, improving the adhesion between the car logo 500 and the foam adhesive 600 and the processing efficiency.

[0029] Furthermore, a clearance hole 312 is provided on the lower side of the pressure block 310, which is matched with the positioning pin 230. When the pressure block 310 is pressed and connected to the pressure seat 200, the clearance hole 312 provides room for the positioning pin 230 to move. After the clearance hole 312 is provided, the vertical length of the positioning pin 230 can be increased. When the foam adhesive 600 is aligned with the positioning pin 230 and placed above the car logo 500, the positioning pin 230 is allowed to protrude from the upper surface of the foam adhesive 600, thereby improving the positioning accuracy of the positioning pin 230 and preventing the foam adhesive 600 from detaching from the positioning pin 230.

[0030] It is understandable that in embodiments where the pressure block 310 does not have a clearance hole 312, when the foam adhesive 600 is aligned with the positioning pin 230 and placed above the car logo 500, the positioning pin 230 should not protrude from the upper surface of the foam adhesive 600, so as to avoid obstructing the protrusion 311 from pressing down on the upper surface of the foam adhesive 600.

[0031] According to some embodiments of this application, refer to Figure 1 and Figure 2 The pressing mechanism 300 also includes a connecting block 320 and a pressing rod 330. The pressing rod 330 is connected to the connecting block 320, the connecting block 320 is connected to the pressing block 310, and the pressing rod 330 is hinged to the base plate 100. The pressing rod 330, hinged to the base plate 100, facilitates pressing the connecting block 320 and the pressing block 310 downwards towards the pressure seat 200, and also facilitates lifting the connecting block 320 and the pressing block 310 upwards away from the pressure seat 200, thus facilitating the pressing and separating operations between the pressure seat 200 and the pressing block 310.

[0032] Furthermore, the base plate 100 includes a rotating support 110, and the lower pressure rod 330 includes a rotating shaft portion 331, which is rotatably connected to the rotating support 110. Specifically, the rotating support 110 is provided with a rotating hole, and the rotating shaft portion 331 is movably inserted into the rotating hole of the rotating support 110. Through the cooperation between the rotating support 110 and the rotating shaft portion 331, the reliability of the hinge connection between the lower pressure rod 330 and the base plate 100 is improved.

[0033] Furthermore, the pressure rod 330 includes a connecting rod portion 332, and the connecting block 320 is detachably connected to the connecting rod portion 332. Specifically, the connecting rod portion 332 is used to connect with the connecting block 320, thereby realizing the connection between the pressure block 310 and the pressure rod 330. The detachable connection between the connecting block 320 and the connecting rod portion 332 facilitates the replacement of the connecting block 320 and the pressure block 310 connected to it.

[0034] Understandably, depending on the shape and size of the car logo 500 to be processed, multiple pressure seats 200 can be set. Different pressure seats 200 have different shapes and sizes of first positioning grooves 210 according to the different shapes and sizes of the car logo 500 to be processed. Multiple pressure blocks 310 and connecting blocks 320 can also be set. Different pressure blocks 310 have different shapes and sizes of protrusions 311 according to the different shapes and sizes of foam adhesive 600 to be processed. When it is necessary to process car logos 500 and foam adhesive 600 of different shapes and sizes, it is only necessary to replace the corresponding pressure seats 200, pressure blocks 310, and connecting blocks 320.

[0035] Furthermore, referring to Figure 1 and Figure 2 The system also includes a spring-loaded mechanism 400, which comprises a fixed post 410 and an elastic connector 420. The fixed post 410 is fixedly connected to the base plate 100, and the fixed post 410 is connected to the lower pressure rod 330 via the elastic connector 420. The two ends of the elastic connector 420 are connected to the fixed post 410 and the lower pressure rod 330, respectively. When the lower pressure rod 330 rotates relative to the base plate 100, it drives the elastic connector 420 to move as well, achieving the stretching or retraction of the elastic connector 420. After the pressure block 310 and the pressure seat 200 are used to press and bond a car logo 500 and a foam adhesive 600, the elastic connector 420 facilitates the automatic return of the lower pressure rod 330, the connector 320, and the pressure block 310 to their original positions, further improving production efficiency.

[0036] Furthermore, a limiting block 430 is connected to the fixed post 410. The limiting block 430 is used to limit the end of the elastic connector 420 connected to the fixed post 410. Specifically, the elastic connector 420 is a rubber ring. One side of the rubber ring is sleeved on the connecting rod portion 332, and the other side of the rubber ring is sleeved on the fixed post 410. At this time, the limiting block 430 is located above the rubber ring. The limiting block 430 can prevent the rubber ring from detaching from the fixed post 410 from above.

[0037] It is understood that, in some other embodiments, reference is made to... Figure 1 and Figure 2The limiting block 430 is a nut, and the circumference of the fixing post 410 is correspondingly provided with threads, and the nut is rotatably connected to the fixing post 410 via these threads. The rotation of the nut relative to the fixing post 410 allows adjustment of the nut's position on the fixing post 410, adjusting the nut's height, and thus adjusting the limiting position of the rubber ring. When it is necessary to increase the elasticity of the rubber ring, the nut can be screwed downwards to stretch the rubber ring; when it is necessary to decrease the elasticity of the rubber ring, the nut can be screwed upwards to retract the rubber ring.

[0038] Working principle: The rubber ring of the rebound mechanism 400 pulls the pressure rod 330 upward, lifting the pressure block 310 away from the pressure seat 200; then the car logo 500 is placed in the first positioning groove 210 and the second positioning groove 220 above the pressure seat 200, thus achieving the positioning of the car logo 500. (Refer to...) Figure 3 The foam adhesive 600 is then placed on top of the car emblem 500, and the positioning hole of the foam adhesive 600 is fitted onto the positioning pin 230. This achieves auxiliary positioning of the foam adhesive 600. (Refer to...) Figure 4 The state is as follows: Press down the pressure rod 330, which drives the connecting block 320 and the pressure block 310 to press down together, so that the pressure block 310 is pressed on the foam adhesive 600. Under the joint clamping of the pressure block 310 and the pressure seat 200, the car logo 500 and the foam adhesive 600 are adhered and bonded. Finally, the rubber ring of the rebound mechanism 400 pulls the pressure rod 330 to move upward, completing one adhesive bonding process.
