DETAILED DESCRIPTION

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This invention provides an automatic adhesive dispensing and labeling machine for motor vehicle electric horns, such as... Figures 1-7 As shown, the device includes a frame 1, and a turntable 2, a dispensing mechanism 3, a pressing mechanism 4, a feeding robot 5, a labeling mechanism 6, and a controller mounted on the frame 1. The controller can be any existing programmable controller such as a PLC. The controller is communicatively connected to the drive components of the turntable 2, the dispensing mechanism 3, the pressing mechanism 4, the feeding robot 5, and the labeling mechanism 6 to coordinate the actions of each part according to a predetermined sequence. The control principle and process are conventional settings in the field and will not be described in detail in this embodiment. Preferably, a positioning camera 15 is also provided, which is also communicatively connected to the controller.

[0032] A turntable drive mechanism 16 is provided between the turntable 2 and the frame 1 to drive the turntable 2 to rotate. The turntable drive mechanism 16 can be any existing electrically controlled rotary drive device, so that the turntable 2 is horizontally rotated on the frame 1 under the control of the controller. The dispensing mechanism 3, the pressing mechanism 4, and the unloading robot 5 are arranged around the turntable 2 in sequence. A horn fixing seat 7 is provided on the top edge of the turntable 2. The number of horn fixing seats 7 is not specifically limited. The preferred number and layout will be given later. The horn fixing seat 7 is used for the bottom surface of the motor vehicle electric horn 8 to be embedded and positioned, so that the motor vehicle electric horn 8 is moved sequentially to the dispensing mechanism 3, the pressing mechanism 4, and the unloading robot 5 as the turntable 2 rotates.

[0033] The glue dispensing mechanism 3 comprises a silicone glue dispensing valve 9, a hot melt glue dispensing valve 10, and a glue dispensing displacement driving mechanism 11. The silicone glue dispensing valve 9 and the hot melt glue dispensing valve 10 are horizontally spaced apart and each has a downward glue outlet. The glue outlet of the silicone glue dispensing valve 9 is used to discharge silicone glue, and the glue outlet of the hot melt glue dispensing valve 10 is used to discharge hot melt glue. The glue dispensing displacement driving mechanism 11 is connected to and drives the silicone glue dispensing valve 9 and the hot melt glue dispensing valve 10 to translate and lift, so as to dispense silicone glue and hot melt glue at predetermined positions on the motor vehicle electric horn 8 respectively. In the embodiment, the specific glue dispensing positions are the interiors of screw seats 29 on the top surface of the motor vehicle electric horn 8. In the embodiment, the glue dispensing displacement driving mechanism 11 comprises a glue dispensing horizontal driving mechanism 18, a silicone glue dispensing valve lifting driving mechanism 19, and a hot melt glue dispensing valve lifting driving mechanism 20. The glue dispensing horizontal driving mechanism 18 can be any existing two-axis linear displacement driving device. The glue dispensing horizontal driving mechanism 18 is connected to and drives the silicone glue dispensing valve lifting driving mechanism 19 and the hot melt glue dispensing valve lifting driving mechanism 20 to horizontally displace in two axes, so as to align the predetermined positions of the motor vehicle electric horn 8. The silicone glue dispensing valve 9 is installed on the silicone glue dispensing valve lifting driving mechanism 19 and is driven by the silicone glue dispensing valve lifting driving mechanism 19 to lift. The hot melt glue dispensing valve 10 is installed on the hot melt glue dispensing valve lifting driving mechanism 20 and is driven by the hot melt glue dispensing valve lifting driving mechanism 20 to lift, so that the silicone glue dispensing valve 9 and the hot melt glue dispensing valve 10 can respectively descend to the top surface of the motor vehicle electric horn 8 to dispense glue.

[0034] The positioning camera 10 is fixed on the rack 1 and located above the turntable 2, and is used to collect the pose of the motor vehicle electric horn 8 on the horn fixing seat 7 downward. Since the controller is also communicatively connected to the driving member (i.e., the glue dispensing displacement driving mechanism 11) of the glue dispensing mechanism 3, the actual pose of the motor vehicle electric horn 8 on the horn fixing seat 7 collected by the positioning camera 10 can be used to control the glue dispensing displacement driving mechanism 11 to displace for compensation during the glue dispensing process, so as to realize precise glue dispensing of the silicone glue dispensing valve 9 and the hot melt glue dispensing valve 10 on the motor vehicle electric horn 8.

[0035] The glue pressing mechanism 4 comprises a glue pressing head 12 and a pressing head lifting driving mechanism 13. The pressing head lifting driving mechanism 13 is connected to and drives the glue pressing head 12 to lift, so as to press toward or away from the motor vehicle electric horn 8. In the embodiment, the glue pressing head 12 is in the form of a columnar shape that can be inserted into the screw seat 9. When the motor vehicle electric horn 8 is displaced to the glue pressing mechanism 4, the glue pressing head 12 is just above the screw seat 9. After the pressing head lifting driving mechanism 13 drives the glue pressing head 12 to descend, the glue pressing head 12 will be inserted into the screw seat 9, so that the silicone glue and the hot melt glue in the screw seat 9 are spread out and overflow the screw seat 9, and the screws in the screw seat 9 and the screw seat 9, and the screw seat 9 and the motor vehicle electric horn 8 are bonded and sealed by the silicone glue and the hot melt glue.

[0036] The labeling mechanism 6 is located at the side of the turntable 2, specifically below the glue pressing mechanism 4 in the embodiment, and the position is not limited. The labeling mechanism 6 has a labeling suction cup 14 facing the turntable 2. The labeling suction cup 14 is driven by a labeling driving mechanism 30 to extend or retract from the top side of the turntable 2. When the motor vehicle electric horn 8 is placed in the horn fixing seat 7, the side of the motor vehicle electric horn 8 facing the outer circle of the turntable 2 is exposed to the horn fixing seat 7. Then, when the labeling suction cup 14 extends from the top side of the turntable 2, it will press the side of the motor vehicle electric horn 8 facing the outer circle of the turntable 2. The labeling suction cup 14 can adsorb the label paper. The label paper adsorbed by the labeling suction cup 14 has adhesion on the side facing the motor vehicle electric horn 8. When the labeling suction cup 14 presses the motor vehicle electric horn 8, the label paper is attached to the motor vehicle electric horn 8. Preferably, in the embodiment, in order to ensure the quality of the label paper, the labeling mechanism 6 further comprises a label pressing mechanism 24 and a label translation driving mechanism 25. The label pressing mechanism 24 comprises a label pressing head 26 and a label pressing head driving mechanism 27. The label pressing head driving mechanism 27 is connected and used to drive the label pressing head 26 to press or move away from the label paper on the motor vehicle electric horn 8. The labeling mechanism 6 and the label pressing mechanism 24 are both installed on the label translation driving mechanism 25 and are driven by the label translation driving mechanism 25 to translate so that the labeling suction cup 14 or the label pressing head 26 is opposite to the motor vehicle electric horn 8.

[0037] The unloading mechanical arm 5 is used to take out the motor vehicle electric horn 8 from the horn fixing seat 7. The unloading mechanical arm 5 can be any existing industrial mechanical arm structure that can realize the above-mentioned action. Specifically, in the embodiment, the unloading mechanical arm 5 comprises an unloading clamping jaw 21, a clamping jaw lifting driving mechanism 22 and a clamping jaw translation driving mechanism 23. The unloading clamping jaw 21 can clamp the motor vehicle electric horn 8. The clamping jaw translation driving mechanism 23 is connected and drives the clamping jaw lifting driving mechanism 22 to translate. The unloading clamping jaw 21 is installed on the clamping jaw lifting driving mechanism 22 and is driven by the clamping jaw lifting driving mechanism 22 to lift.

[0038] The side of the turntable 2 also forms a feeding position. The feeding position has grating doors 28 on both sides. The grating doors 28 are communicatively connected to the controller, so that the motor vehicle electric horn 8 can be fed at the feeding position by an operator or a feeding mechanical arm. When the operator's hands or the feeding mechanical arm are feeding, they will enter the grating doors 28. At this time, the controller will stop the turntable 2, the glue dispensing mechanism 3, the glue pressing mechanism 4, the unloading mechanical arm 5 and the labeling mechanism 6 to ensure safety. Preferably, in the embodiment, four horn fixing seats 7 are evenly distributed on the circumference of the turntable 2. When one horn fixing seat 7 is at the feeding position, the remaining three horn fixing seats 7 are respectively at the glue dispensing mechanism 3, the glue pressing mechanism 4 and the unloading mechanical arm 5 to maximize the production efficiency of the equipment.

[0039] The above merely describes preferred embodiments of the present application, and is not intended to limit the design of the present application. Any equivalent changes made according to the design of the present application shall fall within the protection scope of the present application.
