Description

Technical Field

[0001] This application relates to the technical field of industrial automation, and in particular to an automated device for bonding explosion-proof instrument housing glass. Background Technology

[0002] Explosion-proof instrument housings require the installation of very thick explosion-proof glass. The explosion-proof glass and the instrument housing are bonded together, and the strength of the bond is extremely important for explosion-proof performance. Traditional manufacturing processes mainly rely on manual labor and pressurized equipment. During the process, manual application of adhesive can result in uneven application, and the placement of the explosion-proof glass can lead to contamination and misalignment. This often results in problems such as air bubbles, misalignment, and contamination at the bonding points, leading to a high rate of defects.

[0003] Existing automated devices, equipped with automatic adhesive applicators, use a lower mounting platform that moves along the Y-axis and an upper applicator that moves along the X and Z axes to apply adhesive around the inside of the explosion-proof instrument housing. Then, negative pressure suction accurately places the explosion-proof glass into the housing. While these automated devices replace manual adhesive application and glass placement, the subsequent pressure curing process still requires manual operation, indicating insufficient automation. Furthermore, during the transfer of the explosion-proof instrument housing with the glass inside to the pressing station, some adhesive can harden, making it difficult to effectively remove air bubbles during pressing. This affects the adhesive's filling effect between the explosion-proof glass and the instrument housing, leading to a decrease in product yield. Summary of the Invention

[0016] 2. This application incorporates a sliding heating ring on the dispensing head, which preheats the adhesive inside the dispensing head before application, preventing the adhesive from curing and causing blockage.

[0018] 4. This application achieves a floating connection of the pressure head through the cooperation of the slide, guide rod and spherical block, which can adapt to the flatness error of the explosion-proof glass and the explosion-proof instrument housing, and ensure that the pressing force is evenly distributed on the entire bonding surface, avoiding excessive or insufficient local pressure due to poor flatness, which would affect the bonding quality.

[0019] 5. This application utilizes an air outlet box to blow air onto the bonding surface during the pressing process, accelerating adhesive curing, shortening curing time, and improving production efficiency. Furthermore, the use of a heating coil and temperature sensor enables precise temperature control of the bonding surface.

[0022] The following will be combined with the appendix Figure 1 -Appendix Figure 5 The technical solutions in the embodiments of the present invention are clearly and completely described herein. The described embodiments are only possible technical implementations of the present invention and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of the present invention without creative effort, and these embodiments are also within the protection scope of the present invention.

[0023] This application integrates three key processes—gluing, glass placement, and pressing—into a single machine, significantly improving production efficiency, reducing quality fluctuations caused by manual operation, and further increasing the product qualification rate. The following is a further detailed description of this application: This application discloses an automated device for bonding glass to explosion-proof instrument housings. (Refer to...) Figure 1 The system includes a frame 1, a storage platform 2, a moving platform 3, an automatic glue application mechanism 4, a glass handling mechanism 5, and a pressing mechanism 6. The storage platform 2 is horizontally slidably mounted on the frame 1 and has a first placement slot 21 for placing the explosion-proof instrument housing and a second placement slot 22 for placing the explosion-proof glass. The moving platform 3 is also horizontally slidably mounted on the frame 1. The automatic glue application mechanism 4 is mounted on the moving platform 3 and is used to apply adhesive to the bonding surface inside the explosion-proof instrument housing. The glass handling mechanism 5 removes the explosion-proof glass from the second placement slot 22 and places it inside the explosion-proof instrument housing that has been coated with adhesive. The pressing mechanism 6 is mounted on the glass handling mechanism 5 and is used to press the explosion-proof glass onto the bonding surface of the explosion-proof instrument housing. This fully automates the glass bonding process for the explosion-proof instrument housing, improving production efficiency and product qualification rate.

[0024] Reference Figure 1 Specifically, multiple shelves 2 are provided and slidably mounted on the frame 1 via sliders and guide rails. The sliding directions of each shelf 2 are parallel. Each shelf 2 is provided with multiple first placement slots 21 and second placement slots 22, with each first placement slot 21 corresponding to a second placement slot 22. The shelves 2 are typically flat plate-like structures and can be made of metal, such as aluminum alloy, due to its good strength and corrosion resistance. The frame 1 is provided with a first driving component for driving the sliding of each shelf 2. The first driving component can be a rodless cylinder, a linear motor, etc., as long as it can drive the corresponding shelf 2 to move linearly in the horizontal direction.

[0025] Reference Figure 1 The moving platform 3 is also horizontally mounted on the frame 1 via a slider and guide rail, with its sliding direction perpendicular to the sliding direction of the platform 2. The frame 1 is equipped with a second driving component for driving the moving platform 3 to move horizontally; the structure and working principle of the second driving component are similar to those of the first driving component, and it can also be a rodless cylinder, linear motor, etc., as long as it can drive the moving platform 3 to move in a straight line in the horizontal direction.

[0026] Reference Figure 1 and Figure 2The automatic glue dispensing mechanism 4 includes a lifting frame 41, a third drive component, a glue dispensing cylinder 42, and a positive and negative pressure module 43. The lifting frame 41 is slidably mounted on the moving platform 3 in a vertical direction. The third drive component can be a rodless cylinder, a linear motor, etc., to drive the lifting frame 41 to slide up and down. The glue dispensing cylinder 42 is fixedly mounted on the lifting frame 41, and the lifting frame 41 is equipped with a special shelf for placing the glue dispensing cylinder 42. The glue dispensing cylinder 42 is generally cylindrical and made of plastic or metal, with a glue dispensing head 421 connected to its bottom. The glue dispensing head 421 can be tubular to facilitate the extrusion of adhesive. The glue dispensing cylinder 42 is connected to the positive and negative pressure module 43 through a conduit. The positive and negative pressure module 43 can be an air pump system that applies air pressure to the glue dispensing cylinder 42 to extrude the adhesive from the glue dispensing head 421. During the process of applying adhesive to the bonding surface inside the explosion-proof instrument housing, the platform 2 moves the explosion-proof instrument housing horizontally, and the moving platform 3 moves the adhesive applicator 42 horizontally along the direction perpendicular to the moving platform 2, thereby uniformly applying the adhesive to the bonding surface of the explosion-proof instrument housing.

[0027] Reference Figure 2 and Figure 3 Specifically, a heating ring 44 is slidably mounted on the lifting frame 41 along the length of the dispensing head 421, with the dispensing head 421 passing through the heating ring 44. The lifting frame 41 is equipped with a fourth driving component for driving the heating ring 44 to slide. The heating ring 44 is electrically connected to an electronic control system 7 for supplying power to the heating ring 44. The heating ring 44 is typically a ring structure made of resistance wire wound around a ceramic skeleton, which has good insulation and heat resistance. The fourth driving component can be a small electric push rod, fixed to the lifting frame 41, with its end connected to the heating ring 44. The extension and retraction of the push rod drives the heating ring 44 to slide along the length of the dispensing head 421. The electronic control system 7 can be a control circuit board, connected to the heating ring 44 via wiring, supplying power to the heating ring 44 and controlling its temperature. Alternatively, a cylinder can be used instead of the fourth driving component. By incorporating a sliding heating ring 44 on the dispensing head 421, the adhesive inside the dispensing head 421 can be preheated before dispensing, preventing the adhesive from curing and causing blockage. Simultaneously, it also prevents partially cured adhesive from being directly applied to the bonding surface inside the explosion-proof instrument housing, which could affect the subsequent bonding of the explosion-proof glass, thereby improving product quality and production stability.

[0028] Reference Figure 2 and Figure 4The glass handling mechanism 5 includes a transfer frame 51 vertically slidably mounted on a lifting frame 41, a fifth driving component for driving the transfer frame 51 to slide vertically, and multiple vacuum suction cups 52 located at the bottom of the transfer frame 51. Each vacuum suction cup 52 is connected to the positive and negative pressure module 43 via a conduit. The transfer frame 51 achieves vertical sliding by engaging with the guide rail on the lifting frame 41 via a slider. The fifth driving component can be an electric push rod, with its fixed end mounted on the lifting frame 41 and its end connected to the transfer frame 51. The extension and retraction of the push rod drives the transfer frame 51 to slide up and down. Alternatively, a cylinder can be used instead of an electric push rod, with the extension and retraction of the cylinder achieving the up and down sliding of the transfer frame 51. The vacuum suction cups 52 are typically made of rubber and have good adsorption properties. When the positive and negative pressure module 43 generates negative pressure, the vacuum suction cups 52 adsorb the explosion-proof glass; when positive pressure is generated, the explosion-proof glass is released.

[0029] Reference Figure 2 and Figure 4 The pressing mechanism 6 includes a pressurizing tank 61 fixedly mounted on a transfer frame 51, a pneumatic piston 62 slidably inserted inside the pressurizing tank 61, a pressure rod 63 fixedly mounted on the pneumatic piston 62, and a pressure head 64 located at the end of the pressure rod 63. The pressurizing tank 61 is generally cylindrical, made of metal, and fixed to the transfer frame 51 by bolts. The pneumatic piston 62 is sealed to the inner wall of the pressurizing tank 61, and a rubber sealing ring can be used to ensure a tight seal. The pressure rod 63 is fixedly connected to the pneumatic piston 62, which can be achieved by welding or threading. The pressure rod 63 slides vertically through the transfer frame 51, and the vacuum suction cups 52 are distributed circumferentially along the pressure rod 63. The pressurizing tank 61 is connected to the positive and negative pressure module 43 via a conduit. When the positive and negative pressure module 43 applies air pressure to the pressurizing tank 61, the piston is activated, pushing the pressure rod 63 and the pressure head 64 downwards, pressing the explosion-proof glass onto the bonding surface of the explosion-proof instrument housing.

[0030] Reference Figure 4 Specifically, a pressure sensor 611 is installed inside the pressurization tank 61, and the pressure sensor 611 is electrically connected to the positive and negative pressure module 43. The pressure sensor 611 can be a capacitive pressure sensor, which is installed on the inner wall of the pressurization tank 61 and electrically connected to the positive and negative pressure module 43 through a circuit to monitor the air pressure inside the pressurization tank 61 in real time and feed the signal back to the positive and negative pressure module 43 in order to accurately control the pressure.

[0031] Reference Figure 4 Specifically, the bottom end face of the pressure head 64 is adapted to the end face of the explosion-proof glass, and is usually flat or concave arc-shaped, ensuring uniform pressure distribution during the pressing process and preventing the glass from cracking due to excessive local stress. A soft rubber pad 641 is also provided at the bottom of the pressure head 64. The soft rubber pad 641 can be made of silicone, which can buffer and evenly distribute pressure, absorb the impact force during the pressing process, and protect the glass from damage.

[0032] Reference Figure 4 The end of the pressure rod 63 has a groove along its length. A guide rod 642 is fixedly mounted on the upper part of the pressure head 64. A spherical block 643 is provided at the end of the guide rod 642. The spherical block 643 is adapted to the groove and slidably disposed within the groove. An elastic element 631, which can be a spring, is provided within the groove to drive the pressure head 64 to slide away from the pressure rod 63. A rubber sleeve 632 is also fixedly mounted within the groove and is fitted onto the guide rod 642. This design allows the pressure head 64 to float, adapting to the flatness error of the explosion-proof glass and the explosion-proof instrument housing. This ensures that the pressing force is evenly distributed across the entire bonding surface, avoiding excessive or insufficient local pressure due to poor flatness, which would affect the bonding quality. The rubber sleeve 632 provides a certain lateral elastic support to the pressure head 64, improving its structural stability and precisely controlling its initial position. It also ensures the stability of the pressure head 64 during the pressing process.

[0033] Reference Figure 4 and Figure 5 Furthermore, an air outlet box 8 is provided at the bottom of the transfer frame 51 and along the circumference of the pressure rod 63. The air outlet box 8 has several air outlet holes 81, and each air outlet hole 81 is distributed along the circumference of the air outlet box 8. The air outlet box 8 is also connected to the positive and negative pressure module 43 through a conduit. The air outlet box 8 can blow air onto the bonding surface during the pressing process, accelerate the curing of the adhesive, shorten the curing time, and improve production efficiency.

[0034] Reference Figure 5 A heating coil 82 is provided along the circumference of the side wall of the air outlet box 8. The heating coil 82 is electrically connected to the electronic control system 7. A temperature sensor 83 is provided on the air outlet box 8 to detect the temperature inside the explosion-proof instrument housing, and the temperature sensor 83 is also electrically connected to the electronic control system 7. The heating coil 82 and the temperature sensor 83 enable precise control of the bonding surface temperature. Heating accelerates the curing of the adhesive, while the temperature sensor 83 monitors temperature changes in real time to ensure that the curing process takes place within the optimal temperature range, thereby improving the curing effect of the adhesive.

[0035] The implementation principle of the automated device for bonding explosion-proof instrument housing glass in this application embodiment is as follows: This device integrates three key processes—adhesive application, glass placement, and pressing—into one machine, significantly improving production efficiency. The sliding cooperation between the placement platform 2 and the moving platform 3 achieves precise positioning of the explosion-proof instrument housing and the automatic adhesive application mechanism 4; the automatic adhesive application mechanism 4 replaces manual adhesive application, ensuring uniform adhesive application; the glass handling mechanism 5 achieves precise picking and placing of explosion-proof glass through negative pressure adsorption, avoiding contamination and misalignment; the pressing mechanism 6 immediately presses the glass after placement, ensuring sufficient adhesive filling and timely removal of air bubbles, reducing quality fluctuations caused by manual operation, and further improving the product qualification rate, representing a significant improvement over existing technologies.
