Description

Technical Field

[0001] The present invention belongs to the technical field of glue coating processing, and particularly relates to an automatic glue coating manipulator. Background Art

[0002] In modern industrial production, the glue coating process is a crucial process, which is widely used in many fields such as automobile manufacturing, electronic equipment, furniture production, etc. With the continuous improvement of product quality requirements, the glue coating requirements also increase accordingly.

[0003] Currently, the traditional glue coating method mainly relies on manual operation. However, with the continuous expansion of production scale and the increasing requirements for product quality, manual glue coating gradually exposes many limitations. Manual glue coating is not only inefficient, but also difficult to guarantee the quality and consistency of glue coating. Due to the influence of factors such as fatigue, mood, and skill level in manual operation, problems such as uneven glue coating, inaccurate glue amount control, and unstable glue coating trajectory often occur.

[0004] In order to address the problems existing in manual glue coating, now it has gradually replaced manual work with a manipulator. By pre-programming, the glue coating head moves along a preset route, with stable glue coating quality and high efficiency. For example, an automatic glue coating manipulator disclosed in the patent publication number CN219232862U. However, the range of the traditional three-coordinate glue coating manipulator is small, restricted greatly, and not flexible enough to use. Secondly, during glue coating, due to the instability of the glue supply system (air is mixed into the glue material, resulting in less glue output, or the glue supply pump supplies more glue due to the instability of the power system), defects such as depressions (insufficient glue material) and protrusions (excessive glue material) may occur at the glue coating position, affecting the glue coating quality and being difficult to repair subsequently.

[0035] The repair unit 8 is installed on one side of the glue feeding cylinder 4. And the discharge end of the repair unit 8 is communicated with the glue applying head 6.

This is a mature existing technology, so it will not be elaborated here.

[0039] Now, the operating principle of the present invention is described as follows: Connect the glue feeding connecting pipe 5 to the feeding end of an external glue supply system. Before gluing, program according to the gluing route of the product to be glued and input the programming program into the control box 2. When gluing the product, start the control box 2 and the external glue supply system. After the glue supply system is started, it will supply glue to the inside of the upper insulating sleeve 71 through the glue feeding connecting pipe 5, and the glue will be discharged from the glue applying head 6 through the lower insulating sleeve 72;

[0040] After the control box 2 is started, the control box 2 will control the first rotary drive mechanism 31, the first pitch angle drive mechanism 33, the second pitch angle drive mechanism 35, the telescopic drive mechanism 36, the second rotary drive mechanism 37 and the electric push rod 39 to work according to a pre-programmed procedure. The first rotary drive mechanism 31 can drive the boom 34 to drive the glue feeding cylinder 4 to rotate and adjust the position in a large range in the horizontal direction. The first pitch angle glue drive mechanism can adjust the pitch angle of the glue feeding cylinder 4 in a large range, while the second pitch angle drive mechanism 35 can adjust the pitch angle of the glue feeding cylinder 4 in a small range. The telescopic drive mechanism 36 can adjust the distance between the glue feeding cylinder 4 and the boom 34. The second rotary drive mechanism 37 can control the rotation angle of the glue feeding cylinder 4 in a small range. The electric push rod 39 can adjust the distance between the glue feeding cylinder 4 and the fixed seat 38 within a certain range. Since the control box 2 controls the glue applicator head 6 to move along a preset route and the glue applicator head 6 continuously discharges the glue, the product can be automatically coated with glue;

[0041] When the rubber compound passes through the inside of the rubber feeding cylinder 4, it will pass through the stainless - steel mesh 74. Under the action of the discharge pressure and flow resistance of the rubber compound, the stainless - steel mesh 74 will drive the insulating frame plate 73 to move down a certain distance. At this time, the conductive rod 78 will move down synchronously, so that the contact position between the conductive ring 79 and the conductive rod 78 changes (near the two - thirds position of the conductive rod 78). If the amount of rubber compound transported decreases due to the presence of air or other reasons in the rubber compound, when this part of the rubber compound flows through the stainless - steel mesh 74, because the amount of rubber compound decreases, the discharge pressure and flow resistance become smaller. Therefore, under the action of the spring, the insulating frame plate 73 will drive the conductive rod 78 to move back a certain distance. At this time, the length of the conductive rod 78 connected to the connection circuit between the control box 2 and the conductive ring 79 becomes longer. So, the resistance of the connection circuit of the conductive rod 78, the conductive ring 79 and the control box 2 becomes larger, resulting in a decrease in the intensity of the electrical signal detected by the measurement circuit of the control box 2, which is lower than the threshold range (the threshold refers to the current range of 0.4A to 0.7A). At this time, the control box 2 will output a defect electrical signal to the terminal computer. The terminal computer will use software to represent the product gluing route in a linear form according to a preset program. After the terminal computer receives the defect electrical signal output by the control box 2, the terminal computer will immediately mark a defect label at this position (this position refers to the position where the glue - applying head 6 is located at this time, that is, the position where there is a gluing defect), so as to facilitate subsequent personnel to locate the possible gluing defect position of the product based on the defect mark displayed on the terminal computer. At the same time, if the feeding system suddenly increases its output power due to unstable power supply, the supplied rubber compound will be excessive. At this time, when this part of the rubber compound moves to the position of the stainless - steel mesh 74, due to the excessive rubber compound, the flow pressure and resistance of the rubber compound will become larger. At this time, the stainless - steel mesh 74 drives the conductive rod 78 to move down a larger distance through the insulating frame plate 73, resulting in an increase in the intensity of the electrical signal measured by the measurement circuit of the control box 2 connected to the conductive rod 78 and the conductive ring 79, which is higher than the threshold range. At this time, the control box 2 will also output a defect signal to the terminal computer, and the terminal computer will immediately mark this position;

[0042] Secondly, when too little feeding material is conveyed, when the control box 2 outputs a defective electrical signal to the terminal computer, it will synchronously control the discharge solenoid valve 83 inside the glue replenishing pipe 82 to work regularly for 3 seconds. At this time, a part of the glue material inside the hollow column 81 (before glue application, an appropriate amount of glue material needs to be filled into the hollow column 81 through the glue filling pipe 85 on the side wall of the hollow column 81) will flow into the glue application head 6 through the glue replenishing pipe 82. Thus, when the glue material supplied by the feeding system is too little, appropriate glue replenishment treatment can be carried out at this position, so that the defects caused by too little glue material can be repaired to a certain extent (although the defects can be repaired to a certain extent through glue replenishment, in order to ensure the glue application quality, subsequent personnel still need to check this position according to the defective position marked by the terminal computer to ensure the defect repair quality). When the glue material is too much, the control box 2 will control the feeding solenoid valve 92 inside the shunt pipe 91 to work regularly for 3 seconds, so that the excess glue material can be introduced into the hollow column 81 through the shunt pipe 91, thus avoiding defects such as protrusions at the glue application position caused by the discharge of excess glue material. After the control box 2 is started, the control box 2 will synchronously start the liquid level detector 84. The liquid level detector 84 emits infrared rays and calculates the time when the reflected infrared rays are received, calculates the liquid level height inside the hollow column 81, and outputs an electrical signal to the control box 2 when the glue material inside the hollow column 81 is too much or too little. Subsequently, the control box 2 controls its own alarm module (such as a buzzer) to alarm, reminding the personnel to transfer the excess glue material inside the hollow column 81 out in time or replenish glue material into the hollow column 81;

[0043] After the control box 2 is started, the control box 2 will synchronously start the air pump 101. The suction end of the air pump 101 will generate negative pressure suction at each suction hole 103 through the filter cartridge 105, the connecting hose 104, and the annular hollow strip 102. Under the action of the negative pressure suction, the odor gas volatilized from the just-discharged glue material will be sucked into the filter cartridge 105 and adsorbed and purified by the filter packing 107 inside the filter cartridge 105. Thus, the odor of the glue material volatilization can be prevented from affecting the surrounding air environment, and through the air flow, it can assist the glue material to cure quickly and avoid the glue material from flowing;

[0044] Meanwhile, after the measurement circuit of the control box 2 measures that the electrical signal of the connection loop between the conductive ring 79 and the conductive rod 78 exceeds the threshold, the control box 2 will also control the exhaust solenoid valve 114 to be energized and closed. At this time, the air delivered by the air pump 101 to the inside of the air box 111 cannot be discharged in time. If there are multiple phenomena of too little or too much glue supplied by the glue supply system in a short period of time (for example, more than 5 such phenomena occur within 30 seconds, or such phenomena occur continuously for 10 seconds), then due to the air in the air box 111 not being able to be discharged in time, the air pressure inside the air box 111 will rapidly increase. At this time, under the action of the air pressure, the moving contact of the air pressure automatic switch 115 inside the air box 111 will be pressed back and closed, and the control box 2 will synchronously receive the closing electrical signal of the air pressure automatic switch 115. At this time, the control box 2 will control the entire device to suspend operation and alarm personnel through its own alarm module (the alarm method is different from that when receiving the electrical signal output by the liquid level detector 84, such as an audible and visual alarm, which is convenient for personnel to distinguish). At this time, the staff should immediately maintain and repair the feeding system to ensure the feeding stability of the feeding system.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
