Description

Technical Field

[0001] The present invention relates to the technical field of glue application, and more specifically, to an automatic glue application robot for laser-strengthened parts. Background Art

[0002] The automatic glue application robot for laser-strengthened parts is a high-end industrial equipment that combines laser processing technology and an automatic glue application system. It is mainly used for the glue application process before surface strengthening treatment of metal or composite material parts. Its core function is to precisely coat a special glue film with high temperature resistance and corrosion resistance (such as ceramic glue, metal glue, etc.) on the surface of the parts to enhance the mechanical properties and service life of the parts after laser treatment.

[0003] Laser-strengthened parts have particularly high requirements for mechanical properties. When the parts are in contact with air, especially in a high-temperature environment, an oxide layer will be generated on the surface of the parts due to oxidation. If the surface of the parts cannot be treated, the adhesion of the glue will be reduced, the mechanical properties of the parts after laser strengthening will be unstable, and the service life will be short. The glue application range of the glue application robot is fixed, and it is difficult to change the glue application area according to the shape of the parts, resulting in low glue application efficiency. In summary, an automatic glue application robot for laser-strengthened parts that can change the glue application range is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems of poor glue application adhesion and low glue application efficiency in the prior art.

[0005] The present invention achieves the above purpose through the following technical solutions. An automatic glue application robot for laser-strengthened parts includes a workbench, a fixture, a first robot, and a second robot. The fixture is fixedly connected to the middle of the upper surface of the workbench, and the fixture clamps and positions the workpiece. The first robot and the second robot are respectively fixedly connected to the rear side and the left side of the upper surface of the workbench. A glue tank is installed at the right end of the upper surface of the workbench. A glue application mechanism is installed at the output end of the first robot. The glue tank provides glue to the glue application mechanism. Under the movement of the first robot, the glue application mechanism applies glue to the surface of the workpiece. A pre-treatment mechanism is installed at the output end of the second robot to perform surface treatment on the workpiece before glue application.

[0006] Preferably, the glue application mechanism includes a driving component and a glue discharging component. The driving component is installed at the output end of the first robot, and the glue discharging component is installed at the bottom of the driving component. The glue application range of the glue discharging component is changed under the drive of the driving component.

[0007] Preferably, the purpose is to comprehensively polish the surface of the workpiece, remove the oxide layer on the surface of the workpiece, and improve the adhesion between the glue and the workpiece. The pretreatment mechanism includes a machine shell, a polishing component, and a second motor. The machine shell is installed at the output end of the second robot. The second motor is installed on the upper surface of the machine shell. The polishing component is installed in the inner cavity of the machine shell. The second motor drives the polishing component to work, so that the polishing component polishes the surface of the workpiece and removes the oxide layer on the surface of the workpiece.

[0008] Preferably, the purpose is to drive the glue dispensing component and change the coating range of the glue dispensing component. The driving component includes a driving box installed at the output end of the first robot. A first motor is installed on the right side wall of the driving box. One end of a rotating shaft is installed at the output end of the first motor, and the other end of the rotating shaft is installed on the left inner wall of the driving box through a bearing. Two groups of symmetrically arranged turntables are installed on the outer wall of the rotating shaft. The rotating shaft drives the turntables to rotate under the drive of the first motor. Guide grooves are formed on the outer walls of the turntables.

[0009] Preferably, the shape of the guide groove includes two inner and outer arcs and an inclined groove, and the two arcs are connected by the inclined groove.

[0010] Preferably, the glue dispensing component includes a limiting frame installed on the lower surface of the driving box. A rubber tube is horizontally installed at the bottom rear side of the limiting frame. The rubber tube is connected to the rubber tank through a pipeline, and the rubber tank supplies glue to the rubber tube. A plurality of glue outlet holes are equidistantly formed at the rear side of the limiting frame from left to right. A first rubber head communicating with the glue outlet holes is installed at the center position of the bottom of the inner cavity of the limiting frame. When the glue is extruded from the first rubber head, the first rubber head smears the glue on the surface of the workpiece. Second rubber heads that can slide up and down are inserted into both the left and right sides of the inner cavity of the limiting frame, and the rear sides of the second rubber heads are open. One end of a traction rod is installed at the top of the second rubber head, and the other end of the traction rod is inserted into the inner cavity of the guide groove.

[0011] Preferably, the distance between the glue outlet holes and the second rubber heads is equal to the distance between the two arcs of the guide groove.

[0012] Preferably, the purpose is to enable the polishing disc to rise or fall so that the polishing disc can polish workpieces of different shapes. The polishing component includes a plurality of outer rods installed at the top of the inner cavity of the machine shell from front to back through bearings, and the rightmost outer rod is driven by the second motor. A sprocket is key-connected to the top of the outer wall of the outer rod. A chain is chain-connected to the outer wall of the sprocket. The outer rods rotate synchronously through the transmission of the chain and the sprocket. A spring and an inner rod are respectively inserted into the upper and lower ends of the inner cavity of the outer rod. The inner rod is pushed down under the elastic force of the spring. A polishing disc is installed at the bottom end of the inner rod.

[0013] Preferably, the inner rod is a spline shaft, and the spline part is hidden in the inner cavity of the machine shell.

[0014] The beneficial effects of the present invention are: 1. The present invention drives the sprocket to rotate through the second motor. Under the drive of the sprocket and the chain, all the inner rods can rotate, thereby causing the polishing disc to rotate. Under the action of the spring force, the inner rod is pressed down, so that the polishing disc always adheres to the surface of the workpiece, comprehensively polishes the surface of the workpiece, plays a role in removing impurities from the workpiece, improves the adhesion between the glue and the workpiece, has stable mechanical properties, and has a short service life.

[0015] 2. The present invention drives the turntable to rotate by driving the rotating shaft through the first motor. Under the extrusion of the guide groove, the positioning pin descends, and then the traction rod drives the second rubber head. When the turntable rotates in the reverse direction, the second rubber head rises, changing the glue application range. Therefore, the glue application area can be adjusted according to the shape of the workpiece, improving the glue application efficiency of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the preferred implementation schemes of the present invention will be further described below in conjunction with the specific implementation manners and the drawings.

[0019] Please refer to Figures 1-8, the present invention provides an automatic glue - applying robot for laser - strengthened parts, which includes a workbench 1, a fixture 2, a first robot 3 and a second robot 4. The fixture 2 is fixedly connected to the middle of the upper surface of the workbench 1. The fixture 2 clamps and positions the workpiece. The first robot 3 and the second robot 4 are respectively fixedly connected to the rear side and the left side of the upper surface of the workbench 1. A glue tank 5 is installed at the right end of the upper surface of the workbench 1. A glue - applying mechanism 6 is installed at the output end of the first robot 3. The glue tank 5 supplies glue to the glue - applying mechanism 6. Under the movement of the first robot 3, the glue - applying mechanism 6 applies glue to the surface of the workpiece. A pre - treatment mechanism 7 is installed at the output end of the second robot 4 to perform surface treatment on the workpiece before glue - applying.

[0020] As a preferred solution, furthermore, the glue - applying mechanism 6 includes a driving component 61 and a glue - discharging component 62. The driving component 61 is installed at the output end of the first robot 3, and the glue - discharging component 62 is installed at the bottom of the driving component 61. Under the drive of the driving component 61, the glue - applying range of the glue - discharging component 62 is changed.

[0021] As a preferred solution, furthermore, the driving component 61 includes a driving box 611 installed at the output end of the first robot 3. A first motor 612 is installed on the right - hand side wall of the driving box 611. One end of a rotating shaft 613 is installed at the output end of the first motor 612, and the other end of the rotating shaft 613 is installed on the left - hand inner wall of the driving box 611 through a bearing. Two groups of symmetrically arranged turntables 614 are installed on the outer wall of the rotating shaft 613. Under the drive of the first motor 612, the rotating shaft 613 drives the turntables 614 to rotate. A guide groove 615 is formed on the outer wall of the turntable 614. The shape of the guide groove 615 includes two inner and outer arcs and an inclined groove, and the two arcs are connected by the inclined groove. When the turntable 614 drives the guide groove 615 to rotate, the inclined groove can squeeze the positioning pin 627 downward or upward, so that the traction rod 626 drives the second glue head 625 to rise or fall. The two arcs can keep the positioning pin 627 at a constant height, and the second glue head 625 stays at the current height.

[0022] As a preferred solution, further, the glue discharging assembly 62 includes a limiting frame 621 installed on the lower surface of the driving box 611. A glue pipe 622 is horizontally installed at the bottom of the rear side of the limiting frame 621. The glue pipe 622 is connected to the glue tank 5 through a pipeline, enabling the glue tank 5 to supply glue to the glue pipe 622. A plurality of glue discharging holes 623 are equidistantly formed from left to right at the rear side of the limiting frame 621. A first glue head 624 communicating with the glue discharging holes 623 is installed at the center position of the bottom of the inner cavity of the limiting frame 621. When the glue is extruded from the first glue head 624, the first glue head 624 applies the glue to the surface of the workpiece. Second glue heads 625 that can slide up and down are inserted into both the left and right sides of the inner cavity of the limiting frame 621, and the rear sides of the second glue heads 625 are open. One end of a traction rod 626 is installed at the top of the second glue head 625, and the other end of the traction rod 626 is inserted into the inner cavity of the guide groove 615. The distance between the glue discharging holes 623 and the second glue heads 625 is equal to the distance between two arcs of the guide groove 615. After the second glue heads 625 descend, the second glue heads 625 can be communicated with the glue discharging holes 623.

[0023] As a preferred solution, further, the pre-treatment mechanism 7 includes a machine shell 71, a polishing assembly 72, and a second motor 74. The machine shell 71 is installed at the output end of the second robot 4. The second motor 74 is installed on the upper surface of the machine shell 71. The polishing assembly 72 is installed in the inner cavity of the machine shell 71. The second motor 74 is used to drive the polishing assembly 72 to work, so that the polishing assembly 72 polishes the surface of the workpiece and removes the oxide layer on the surface of the workpiece. An air knife 73 is installed on the left side wall of the machine shell 71. The air knife 73 is connected to a dust suction fan through a pipeline. Under the suction of the dust suction fan, the air knife 73 sucks away the impurities on the surface of the workpiece. A vibration motor 75 is installed in the middle of the right side wall of the machine shell 71. The vibration motor 75 drives the machine shell 71 to vibrate, shaking off the impurities on the polishing assembly 72 and enabling the polishing assembly 72 to always maintain a good polishing effect.

[0024] As a preferred solution, further, the polishing assembly 72 includes a plurality of outer rods 721 installed at the top of the inner cavity of the machine shell 71 through bearings from front to back, and the rightmost outer rod 721 is driven by the second motor 74. A sprocket 722 is key-connected to the top of the outer wall of the outer rod 721. A chain 723 is chain-connected to the outer wall of the sprocket 722. The outer rods 721 are synchronously rotated through the transmission of the chain 723 and the sprocket 722. Springs 724 and inner rods 725 are respectively inserted into the upper and lower ends of the inner cavity of the outer rod 721. Under the elastic force of the springs 724, the inner rods 725 are pushed to descend. The inner rods 725 are spline shafts, and the spline parts are hidden in the inner cavity of the machine shell 71. The inner rods 725 can not only rotate following the outer rods 721 but also limit the descending position of the polishing discs 726. Polishing discs 726 are installed at the bottom ends of the inner rods 725.

[0025] Working principle: Step 1: Position the workpiece through the fixture 2. The second robot 4 moves the pre-treatment mechanism 7 along the surface of the workpiece from left to right. Under the elastic force of the spring 724, the polishing disc 726 is pushed to always adhere to the surface of the workpiece. The second motor 74 drives the sprocket 722 to rotate. Under the transmission of the sprocket 722 and the chain 723, the polishing disc 726 rotates. The polishing disc 726 polishes the oxide layer on the surface of the workpiece, and the air knife 73 sucks away the generated impurities, realizing the pre-treatment of the workpiece before gluing. Step 2: Drive the gluing mechanism 6 along the surface of the workpiece through the first robot 3. The glue tank 5 conveys glue into the glue pipe 622. The glue passes through the glue outlet hole 623 and is extruded from the first glue head 624 to glue the surface of the workpiece. Step 3: When it is necessary to change the gluing range, the first motor 612 drives the rotating shaft 613 to drive the turntable 614 to rotate. The guide groove 615 rotates following the turntable 614. When the positioning pin 627 moves from the inner arc of the guide groove 615 to the inclined groove, the inclined groove presses down on the positioning pin 627. When the positioning pin 627 reaches the outer arc of the guide groove 615, the second glue head 625 descends and then remains stationary, enabling the second glue head 625 to communicate with the glue outlet hole 623. The lengths of the first glue head 624 and the second glue head 625 increase, improving the gluing efficiency of the workpiece.

[0026] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.
