Description

Technical Field

[0001] This utility model relates to the field of foam adhesive technology, and in particular to a positioning device for foam adhesive. Background Technology

[0002] In the foam bonding process, the positioning stage has a significant impact on the final product quality. Currently, the positioning methods in the industry have many shortcomings. On the one hand, manual positioning relies on the experience and skill of workers, which is extremely inefficient and difficult to guarantee accuracy. Deviations in the bonding position of foam and double-sided tape often occur, resulting in a high product defect rate, increasing production costs, and seriously affecting production progress.

[0003] On the other hand, existing automated positioning equipment is not very stable and its adaptability to foams of different sizes and shapes is obviously insufficient. In actual production, when product specifications are frequently changed, the equipment is difficult to adjust the positioning parameters quickly and accurately, resulting in a significant reduction in production efficiency. Moreover, these devices generally lack real-time monitoring and adjustment mechanisms. Once a positional deviation occurs during the adhesive application process, it cannot be corrected in time, which seriously affects the accuracy and stability of adhesive application and thus affects product quality.

[0004] The purpose of this utility model is to provide a positioning device for foam adhesive application, so as to solve the problems of poor positioning accuracy, low efficiency, insufficient equipment adaptability and lack of real-time monitoring and adjustment mechanism in the existing technology, and improve the quality and production efficiency of foam adhesive application. Summary of the Invention

A precision positioning groove is provided between the positioning base plate and the positioning pressure plate. During use, the positioning groove between the positioning base plate and the positioning pressure plate facilitates the positioning of the foam. The positioning pin facilitates precise restriction of the foam in the X, Y, and Z directions and in the rotational degrees of freedom around the three axes, achieving high-precision positioning on the pressing platform.

The positioning base plate 103 is fixedly connected to the pressing platform 102 and located on top of the pressing platform 102. The positioning pressure plate 104 is detachably connected to the positioning base plate 103 and located on top of the positioning base plate 103. Multiple positioning pins 105 are used, each threadedly connected to the positioning base plate 103 and passing through the positioning pressure plate 104. The conveying assembly is connected to the die-cutting machine body... The die-cutting machine body 101 is connected to the positioning assembly. The die-cutting machine body 101 is used to die-cut the foam after adhesive application and provides support for the device. The pressing platform 102 provides support for the positioning assembly. The positioning base plate 103 provides positioning for the foam, the foam adhesive application, and the foam adhesive removal. The positioning pressure plate 104 provides fixing for the foam, the foam adhesive application, and the foam adhesive removal. The positioning pin 105 facilitates the fixing of the positioning base plate 103 and the positioning pressure plate 104. The positioning pin 105 is made of 304 stainless steel and has a hardness of HRC after quenching treatment. 40-45, with a conical top, a precision positioning groove is provided between the positioning base plate 103 and the positioning pressure plate 104. During use, the positioning groove between the positioning base plate 103 and the positioning pressure plate 104 facilitates the positioning of the foam. The positioning pin 105 facilitates precise restriction of the foam in the X, Y, and Z directions and in the rotational degrees of freedom around the three axes, achieving high-precision positioning on the pressing platform 102 and effectively preventing displacement during subsequent bonding.

[0021] The conveyor frame 106 is fixedly connected to the die-cutting machine body 101 and located on the back of the die-cutting machine body 101. There are two feeding bearing seats 107, each detachably connected to the conveyor frame 106 and located on the top of the conveyor frame 106. There are two feeding shafts 108, each rotatably connected to the feeding bearing seat 107 and passing through it. 106 provides support and guidance for the conveying assembly. The feeding bearing seat 107 is equipped with a ball bearing to provide limiting and support for the feeding shaft 108. The feeding shaft 108 is used to convey the double-sided tape to the foam after positioning by the positioning pressure plate 104 and the positioning base plate 103, which facilitates the feeding of the double-sided tape. The two ends of the feeding shaft 108 are provided with a tightening sleeve structure, which can be adapted to double-sided tape rolls with different inner diameters to achieve quick loading and unloading and ensure continuous tape supply.

[0022] Secondly, there are multiple transition mounting seats 109, each detachably connected to the conveyor frame 106 and located on the outer side of the conveyor frame 106. There are multiple transition moving seats 110, each slidably connected to the transition mounting seats 109 and located in the middle of the transition mounting seats 109.

During installation, the transition shafts 111 are kept at a 15° installation angle with the feeding shaft 108. The double-sided tape guided by the feeding shaft 108 is then guided by the transition shafts 111, facilitating the guidance of the double-sided tape to the top of the foam.

[0023] Furthermore, the pressure seat 112 is detachably connected to the die-cutting machine body 101 and is located inside the pressure platform 102.

The pressure roller 113 is made of polyurethane rubber with a Shore A hardness of 60-70. The width of the roller body is adapted to the foam. The pressure roller 113 is driven by a cylinder and its extension and retraction are controlled by a solenoid valve. After the foam is positioned by the positioning component, the solenoid valve is energized, and the cylinder pushes the pressure roller 113 down, so that the double-sided tape and the upper surface of the foam to be adhered are tightly pressed together. The pressing pressure is monitored in real time by a pressure sensor and fed back to the control system to ensure that the pressure is stable within a suitable range.

[0024] Finally, the feeding fixed shaft 114 is rotatably connected to the pressing platform 102 and passes through the pressing platform 102. There are multiple feeding conveying shafts 115, which are rotatably connected to the die-cutting machine body 101 and located below the pressing platform 102. The feeding fixed shaft 114 is used to guide the double-sided tape at the bottom of the foam, and the feeding conveying shaft 115 is used to guide the double-sided tape to the feeding fixed shaft 114, so as to facilitate the conveying of the double-sided tape at the bottom of the foam.

The positioning pin 105 is made of 304 stainless steel and has a hardness of HRC 40-45 after quenching treatment. The top is conical. A precision positioning groove is provided between the positioning base plate 103 and the positioning pressure plate 104. During use, the positioning groove between the positioning base plate 103 and the positioning pressure plate 104 facilitates the positioning of the foam. The positioning pin 105 facilitates positioning from X, Y, Z. The foam is precisely restricted in three directions and rotational degrees of freedom around three axes, achieving high-precision positioning on the pressing platform 102. This effectively prevents displacement during subsequent bonding, solving the problems of poor positioning accuracy, low efficiency, insufficient equipment adaptability, and lack of real-time monitoring and adjustment mechanisms in the existing technology, thereby improving the quality and production efficiency of foam bonding.
