[0002] Existing workpiece adhesive application clamping equipment mostly uses a single mechanical clamping method to hold and fix the workpiece. The rigid mechanical clamping structure is prone to damaging the workpiece surface and causing damage. When the workpiece rotates at high speed for adhesive application, it is prone to displacement and loosening, resulting in defects such as uneven adhesive thickness, missed areas, and dry areas. Traditional equipment lacks a clamping status verification structure, making it impossible to promptly identify abnormalities such as insufficient material, misalignment, or air leakage, leading to a high product defect rate. To address these issues, we have introduced a workpiece adhesive application clamping device. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Please see Figures 1-16 The present invention provides a technical solution: A workpiece gluing and clamping device includes a worktable 1, on which a guide rail 2 for sliding a movable seat 6 is provided. A top seat 26 is fixed on the movable seat 6 by a column 14. An intermediate gear 27 driven to rotate by a first servo motor 15 is provided at the center of the upper end of the top seat 26. Side gears 24 are meshed at equal intervals on the side of the intermediate gear 27. A hollow cylinder 20 is fixed through the middle of the side gears 24. The lower end of the hollow cylinder 20 extends through the top seat 26 and is connected to a rotary joint 18. The hollow cylinder 20 is fixed with a clamping seat 21 for mounting a circular workpiece 8. The hollow cylinder 20 is connected to the negative pressure suction cup 33 in the middle of the clamping seat 21. An ejector cylinder 42 is sleeved on the outside of the negative pressure suction cup 33. A limit ring 41 is fixed at the lower end of the ejector cylinder 42. The limit protrusion 29 on the side of the limit ring 41 slides in the limit groove 28 on the side of the clamping seat 21. A pressure sensor 30 is provided in the limit groove 28. The upper end of the clamping seat 21 is provided with a hollow clamping rubber protrusion 32 that is inserted into the inner groove 43 at the bottom of the circular workpiece 8. The inner side of the clamping seat 21 is provided with an ejector. The top of the ejector is connected to the ejector cylinder 42, and the bottom of the ejector is connected to the corresponding hollow clamping rubber protrusion 32. The upper end of the workbench 1 is also provided with an industrial robotic arm 5, and the end of the industrial robotic arm 5 is provided with a glue gun head 9 for applying glue to a circular workpiece 8. When the negative pressure suction cup 33 clamps the circular workpiece 8, the ejector cylinder 42 moves down, and the hollow clamping rubber protrusion 32 expands and gets into the inner groove 43 of the workpiece through the ejector to complete the clamping. The limiting protrusion 29 presses against the pressure sensor 30 to verify the clamping status of the circular workpiece 8. After the negative pressure of the negative pressure suction cup 33 is cut off, the ejector drives the ejector cylinder 42 to rise and reset. At the same time, the hollow clamping rubber protrusion 32 retracts, and the ejector cylinder 42 lifts the circular workpiece 8 to complete the unloading.

[0020] A second servo motor 10 is fixed at one end of the guide rail 2. A lead screw 13 is provided at the output end of the second servo motor 10. The lower middle part of the moving seat 6 is slidably connected to the inside of the guide rail 2. The lead screw 13 is threaded through and screwed into the lower middle part of the moving seat 6.

[0021] The movable seat 6 extends from both sides via horizontal slots 11 on the side of the guide rail 2 and is connected to rollers 12, which roll on the upper surface of the side of the guide rail 2.

[0022] The workbench 1 is the base for the entire machine. The guide rail 2 is fixedly laid on the workbench 1. The second servo motor 10 is fixedly installed at one end of the guide rail 2. Its output end is connected to the lead screw 13. The lead screw 13 is threaded through and engaged in the middle of the lower end of the moving seat 6. The main body of the movable seat 6 is slidably assembled inside the guide rail 2. The structures on both sides of the movable seat 6 extend outward through the horizontal slots 11 opened on the side of the guide rail 2 and are equipped with rollers 12. The rollers 12 support and roll against the upper end face of the side of the guide rail 2, share the load of the movable seat 6, and improve the smoothness of sliding.

[0023] The controller 4 sends an electrical signal to the second servo motor 10, driving the lead screw 13 to rotate in the forward and reverse directions. Relying on the lead screw thread pair transmission, the moving seat 6 is driven to slide back and forth in a straight line along the guide rail 2, thereby driving the top seat 26 and all clamping positions to move synchronously, completing the alignment adjustment between the workpiece position and the glue gun head 9.

[0024] The top seat 26 is provided with a bracket 16 at its lower end. The first servo motor 15 is installed at the lower end of the bracket 16. The shaft 17 of the output end of the first servo motor 15 extends through the top seat 26 and is connected to the middle of the lower end of the intermediate gear 27. The upper middle part of the top seat 26 is provided with an intermediate bearing cylinder 22, and the intermediate bearing cylinder 22 is provided with an intermediate bearing sleeved on the rotating shaft 17.

[0025] The upper side of the top seat 26 is provided with side bearing cylinders 23 at equal intervals. The side bearing cylinders 23 are provided with side bearings that are sleeved on the hollow cylinder 20. The top of the hollow cylinder 20 is provided with a connecting flange 25 that is fixed to the bottom of the clamping seat 21.

[0026] The controller 4 outputs a control signal to drive the first servo motor 15 to run. The rotating shaft 17 drives the intermediate gear 27 to rotate at a constant speed. Relying on gear meshing transmission, it synchronously drives all side gears 24, hollow cylinder 20, clamping seat 21 and the clamped circular workpiece 8 to rotate at the same speed, ensuring that the glue application speed of the multi-station workpiece is uniform and the glue application thickness is uniform.

[0027] The rotary joint 18 is connected to the negative pressure pump via a pipe, and a solenoid valve is provided on the pipe.

[0028] The lower end of the hollow cylinder 20 extends downward through the top seat 26 and is fitted with a rotary joint 18. One side of the rotary joint 18 is connected to a negative pressure pipeline (pipeline). The pipeline is connected in series with a solenoid valve and then to a negative pressure pump. The rotary joint 18 can keep the negative pressure air path sealed and open while the hollow cylinder 20 is rotating continuously, thus preventing air leakage during the rotation process.

[0029] A protective cover 7 is provided on the outside of the top seat 26, and the intermediate gear 27 and the side gear 24 are located inside the protective cover 7. The protective cover 7 is installed on the outside of the top seat 26 to enclose and protect the intermediate gear 27 and the side gear 24, preventing dust and adhesive from contaminating the gear pair.

[0030] The lower end of the negative pressure suction cup 33 is provided with a docking cylinder 31 that communicates with the top of the hollow cylinder 20. The middle part of the negative pressure suction cup 33 is provided with a central adsorption hole 34 that communicates with the top of the docking cylinder 31. Side adsorption holes 35 are evenly distributed on the inner side of the negative pressure suction cup 33. The side adsorption holes 35 are connected to the top side of the docking cylinder 31 through the first channel 40 inside the negative pressure suction cup 33. The inner diameter of the top of the docking cylinder 31 gradually decreases.

[0031] The negative pressure suction cup 33 has a central adsorption hole 34 in the center and multiple sets of side adsorption holes 35 are evenly opened on the inner side of the negative pressure suction cup 33. The side adsorption holes 35 are connected to the top side of the docking cylinder 31 through the first channel 40 inside the suction cup. The top of the docking cylinder 31 adopts a gradually narrowing inner diameter structure to gather negative pressure airflow and improve adsorption suction. A sealing ring 38 is embedded in the side of the negative pressure suction cup 33. The sealing ring 38 seals the connection between the outer side of the negative pressure suction cup 33 and the inner wall of the ejector cylinder 42, ensuring that the negative pressure vacuum cavity formed between the negative pressure suction cup 33, the inner wall of the ejector cylinder 42 and the bottom surface of the circular workpiece 8 does not leak. The limiting ring 41 is sleeved on the outside of the docking cylinder 31.

[0032] The clamping seat 21 is provided with a protrusion located on the side of the limiting groove 28, and the hollow clamping rubber protrusion 32 is fixed on the upper end of the protrusion. The inner side of the protruding seat is provided with an arc-shaped groove 36, and the outer wall of the ejector cylinder 42 is in contact with the inner wall of the arc-shaped groove 36; After the hollow clamping rubber protrusion 32 expands, it can be embedded in the pre-set inner groove 43 at the bottom of the circular workpiece 8 to clamp and fix the circular workpiece 8 and prevent the circular workpiece 8 from radially shifting when rotating.

[0033] The ejector includes a cylinder 37 mounted on an arc-shaped groove 36, a piston disc 45 slidably mounted inside the cylinder 37, a spring 19 fixed to the bottom of the piston disc 45, and a lifting rod 44 fixed to the upper end of the piston disc 45. The lifting rod 44 extends through the cylinder 37 and is connected to the lower end of the ejector cylinder 42. The bottom of the cylinder barrel 37 is connected to the corresponding hollow clamping rubber protrusion 32 via a second channel 39.

[0034] The workbench 1 is also equipped with a controller 4 via a vertical plate 3. The controller 4 is electrically connected to the first servo motor 15, the second servo motor 10, the negative pressure pump, the solenoid valve, the industrial robotic arm 5, the glue gun head 9, and the pressure sensor 30.

[0035] Specifically, when using it: The circular workpiece 8 is placed on the upper end of the clamping seat 21, and the lower end of the circular workpiece 8 sits on the upper surface of the ejector cylinder 42, so that the top of the hollow clamping rubber protrusion seat 32 is initially inserted into the inner groove 43 at the bottom of the circular workpiece 8. Subsequently, the controller 4 turns on the negative pressure pump and the solenoid valve. After passing through the rotary joint 18, the hollow cylinder 20, and the docking cylinder 31, the negative pressure airflow simultaneously draws air outward from the middle adsorption hole 34 and the side adsorption hole 35, forming a negative pressure vacuum cavity between the inner wall of the negative pressure suction cup 33 and the ejection cylinder 42 and the bottom surface of the circular workpiece 8. As the air in the negative pressure vacuum chamber is gradually discharged under the continuous operation of the negative pressure pump, the circular workpiece 8 will press down on the ejector cylinder 42. The ejector cylinder 42 moves down relative to the negative pressure suction cup 33 until the negative pressure suction cup 33 firmly sucks and fixes the lower surface of the circular workpiece 8. At the same time, as the ejector cylinder 42 moves downward, the ejector cylinder 42 presses down the spring 19 through the lifting rod 44 and the piston disc 45. When the piston disc 45 moves downward along the cylinder 37, it will press the air inside the cylinder 37 into the hollow clamping rubber protrusion 32 through the second channel 39. This causes the hollow clamping rubber protrusion 32 to expand and become larger, and then be tensioned in the inner groove 43 at the bottom of the circular workpiece 8, thereby achieving the clamping and fixing of the circular workpiece 8. Simultaneously, as the ejector cylinder 42 moves downward, it will cause the limiting protrusion 29 to move downward through the limiting ring 41 until the limiting protrusion 29 presses down on the pressure sensor 30. The pressure sensor 30 collects the pressure value in real time and transmits it back to the controller 4. The controller 4 determines the following based on the pressure value: When the pressure reaches the preset threshold, it is determined that the circular workpiece 8 is placed normally and effectively adsorbed, and the glue application process can be started. Pressure below the threshold: If the workpiece is found to be missing material, misplaced, or has air leakage, controller 4 will lock the equipment, stop the glue application, and output an alarm signal to prevent defects such as dry coating or missed coating.

[0036] The negative pressure suction cup 33 firmly adheres to the lower surface of the circular workpiece 8. Combined with the hollow clamping rubber protrusion seat 32 embedded in the inner groove 43, it achieves double flexible clamping and positioning of the circular workpiece 8, which will not cause damage to the circular workpiece 8 and ensures that the circular workpiece 8 does not loosen or shift when rotating at high speed to apply glue.

[0037] When the pressure sensor 30 sends a signal that the workpiece clamping is qualified, the controller 4 controls the second servo motor 10 to drive the moving seat 6 to slide, so as to accurately move the round workpiece 8 to be coated with glue to the glue coating area. Subsequently, the controller 4 controls the industrial robotic arm 5 to adjust the height, horizontal position, and tilt angle of the glue gun head 9 in multi-axis linkage, so that the glue outlet of the glue gun head 9 is aligned with the glue surface of the circular workpiece 8. The controller 4 controls the first servo motor 15 to drive the circular workpiece 8 to rotate at a uniform speed. The controller 4 simultaneously opens the glue gun head 9 to dispense glue, and uniformly completes the ring / full surface glue application on the surface of the circular workpiece 8. After the glue application process is completed, the controller 4 first closes the solenoid valve to cut off the negative pressure, the negative pressure pump stops pumping air, and the vacuum suction force disappears. At this time, under the elastic force of the spring 19 on the piston disc 45, the piston disc 45, the lifting rod 44 and the ejector cylinder 42 are lifted upward synchronously. At the same time, the piston disc 45 forms a negative pressure inside the cylinder 37, which draws in the air inside the hollow clamping rubber protrusion 32. The hollow clamping rubber protrusion 32 gradually shrinks and becomes smaller, and the outer wall of the hollow clamping rubber protrusion 32 is no longer tightly attached to the inner wall of the inner groove 43. The ejector cylinder 42 is raised upwards, lifting the circular workpiece 8 to complete the automatic unloading.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
