Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap processing equipment, and more specifically, to a coating treatment device for bottle cap parts. Background Art

[0002] Figure 4 Shown is an exploded view of a bottle cap product, which includes a bottle cap part and a stopper part. A stopper mounting hole is provided in the bottle cap part. The stopper part is inserted into the stopper mounting hole and adhesively connected to the bottle cap part. An adhesive boss is provided in the stopper mounting hole. The stopper part contacts the adhesive boss and is adhesively joined together by heating. In order to make the bottle cap product have a delicate appearance, the bottle cap part is taken for coating operation. Considering the high efficiency of the coating operation, the bottle cap part is coated by overall immersion. Therefore, a coating is also formed at the position of the adhesive boss of the bottle cap part. The presence of the coating makes it impossible for the stopper part to be connected to the adhesive boss by heating. Therefore, before the stopper part is installed, it is first necessary to scrape the coating at the position of the adhesive boss of the bottle cap part. This is the coating treatment operation for the bottle cap part. Currently, this operation is still completed manually, which has the disadvantages of a large amount of manual labor and low operation efficiency, and cannot meet the production requirements of a large number of bottle cap products. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a coating treatment device for bottle cap parts. In this device, the bottle cap part rotates with the tooling turntable, and the coating scraping operation at the position of the adhesive boss is completed through the cooperation of a grinding treatment mechanism and a pressing auxiliary mechanism at the coating treatment station. This device has the advantages of high automation and high production efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A coating treatment device for bottle cap parts, including a tooling turntable, a grinding treatment mechanism and a pressing auxiliary mechanism. The tooling turntable is rotatably installed. An inlet station, a coating treatment station and an outlet station are arranged along the rotation direction of the tooling turntable. Four gripper mechanisms are evenly installed on the outer edge of the tooling turntable. During the rotation of the tooling turntable, the gripper mechanisms can sequentially pass through the inlet station, the coating treatment station and the outlet station. An inlet conveyor belt is installed at the inlet station. The gripper mechanisms can individually grab bottle cap parts from the inlet conveyor belt. The grinding treatment mechanism and the pressing auxiliary mechanism are installed at the coating treatment station. The grinding treatment mechanism and the pressing auxiliary mechanism can cooperate to complete the coating treatment operation of the bottle cap parts. An outlet conveyor belt is installed at the outlet station. The gripper mechanisms can individually release the processed bottle cap parts onto the outlet conveyor belt for output.

[0006] Further, the gripper mechanism includes an elastic lifting seat and a mechanical gripper. The elastic lifting seat is fixedly installed on the disk surface of the tooling turntable. The mechanical gripper is movably connected to the elastic lifting seat. The mechanical gripper is used to grasp a single bottle cap part, and the mechanical gripper can achieve vertical lifting motion.

[0007] Further, the elastic lifting seat includes a fixed seat, a vertical shaft, and a manipulator mounting base. The fixed seat is fixedly installed on the disk surface of the tooling turntable. Two parallel shaft plates are connected to the side wall of the fixed seat. The vertical shaft is fixedly connected between the two shaft plates. One end of the manipulator mounting base is inserted through the vertical shaft. The mechanical gripper is fixed on the manipulator mounting base. A spring is sleeved outside the vertical shaft. The manipulator mounting base presses on the spring.

A plurality of grinding blades are evenly installed on the blade mounting ring. The grinding blades are installed with their cutting edges facing up.

[0009] Further, as the tooling turntable rotates, the mechanical gripper grasps the bottle cap part and comes to the coating treatment station. At this time, the manipulator mounting base is only affected by the spring force. The mechanical gripper is at the highest point. The bottle cap part does not contact the grinding seat. After the mechanical gripper moves downward, it can drive the bottle cap part to insert into the bottle cap treatment cavity of the grinding seat. The bottle cap part is provided with a bottle stopper mounting hole, and an adhesive boss is provided in the bottle stopper mounting hole. After the bottle cap part is inserted into the bottle cap treatment cavity, the adhesive boss can contact the cutting edge of the grinding blade.

[0010] Further, the pressing auxiliary mechanism includes a pressing frame and a pressing push cylinder. The pressing push cylinder is vertically installed downward on the pressing frame. The piston rod end of the pressing push cylinder is connected with a pressing push head. The pressing push head is correspondingly arranged directly above the bottle cap treatment cavity.

[0011] Further, the highest lifting height of the pressing push head is higher than the highest height of the bottle cap part. The pressing push cylinder can drive the pressing push head to descend.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] As Figures 1-3A coating treatment device for a bottle cap part as shown includes a tooling turntable 1, a grinding treatment mechanism 4 and a pressing auxiliary mechanism 5. The tooling turntable 1 is rotatably installed. The tooling turntable 1 is designed with a motor drive structure, which is a conventional technology and will not be introduced in detail here. Along the rotation direction of the tooling turntable 1, there are a feeding station 11, a coating treatment station 12 and a discharging station 13. Four gripper mechanisms 2 are evenly installed on the outer edge of the tooling turntable 1. During the rotation of the tooling turntable 1, the gripper mechanisms 2 can sequentially pass through the feeding station 11, the coating treatment station 12 and the discharging station 13. The tooling turntable 1 is set to rotate 90 degrees each time, so as to ensure that each time there is a gripper mechanism 2 corresponding to a respective station. The feeding station 11 is equipped with a feeding conveyor belt 3, and the feeding conveyor belt 3 conveys the bottle cap parts 71 one by one, and its rhythm frequency matches the arrival frequency of the gripper mechanism 2. Each time the gripper mechanism 2 arrives at the feeding conveyor belt 3, it can successfully grab a bottle cap part 71. The grinding treatment mechanism 4 and the pressing auxiliary mechanism 5 are installed at the coating treatment station 12. As the tooling turntable 1 rotates, the gripper mechanism 2 grabs the bottle cap part 71 and comes to the coating treatment station 12, and the grinding treatment mechanism 4 and the pressing auxiliary mechanism 5 can cooperate to complete the coating treatment operation of the bottle cap part 71, such as Figure 4 A bottle cap product as shown includes a bottle cap part 71 and a bottle stopper part 72. The bottle cap part 71 is provided with a bottle stopper mounting hole 711, and an adhesion boss 712 is provided in the bottle stopper mounting hole 711. The bottle stopper part 72 is inserted into the bottle stopper mounting hole 711, and the bottle stopper part 72 can be thermally bonded to the adhesion boss 712. However, after the coating operation of the bottle cap part 71, there will be a coating at the position of the adhesion boss 712, which affects the bonding between the bottle stopper part 72 and the adhesion boss 712. It is necessary to first scrape off the coating at the position of the adhesion boss 712. This operation is the coating treatment operation of the bottle cap part 71. In the present utility model, the scraping operation of the coating at the position of the adhesion boss 712 is completed through the coordinated action of the grinding treatment mechanism 4 and the pressing auxiliary mechanism 5. During the coating treatment operation, the bottle cap part 71 is still in the grasping state of the gripper mechanism 2. The discharging station 13 is equipped with a discharging conveyor belt 6. As the tooling turntable 1 continues to rotate, the gripper mechanism 2 grabs the bottle cap part 71 and comes to the discharging station 13. At this time, the gripper mechanism 2 releases the grasping, and the gripper mechanism 2 can release the processed bottle cap parts 71 one by one onto the discharging conveyor belt 6 for output. The present utility model has the advantage of high automation. A series of operations such as feeding, coating treatment, and discharging of the bottle cap part 71 can be automatically completed. The application of the present utility model can greatly reduce the use of labor, improve production efficiency, and can well meet the production requirements of a large number of bottle cap products.

[0021] such as Figure 2As shown in the figure, the gripper mechanism 2 includes an elastic lifting seat 21 and a mechanical gripper 22. The elastic lifting seat 21 is fixedly installed on the disk surface of the tooling turntable 1, and the mechanical gripper 22 is movably connected to the elastic lifting seat 21. The mechanical gripper 22 is used to grasp a single bottle cap part 71, and the mechanical gripper 22 can realize vertical lifting movement. In the coating treatment operation of the bottle cap part 71, the lifting movement of the bottle cap part 71 needs to be realized. Therefore, the mechanical gripper 22 for grasping the bottle cap part 71 also needs to be able to perform vertical lifting movement.

[0022] As Figure 2 shown in the figure, the elastic lifting seat 21 includes a fixed seat 211, a vertical shaft 213, and a manipulator mounting base 214. The fixed seat 211 is fixedly installed on the disk surface of the tooling turntable 1. Two parallel shaft plates 212 are connected to the side wall of the fixed seat 211. The vertical shaft 213 is fixedly connected between the two shaft plates 212. One end of the manipulator mounting base 214 is inserted onto the vertical shaft 213. The vertical shaft 213 plays a role in guiding the movement of the manipulator mounting base 214. The vertical shaft 213 is installed vertically. Therefore, the manipulator mounting base 214 can perform vertical lifting movement. The mechanical gripper 22 is fixed on the manipulator mounting base 214, and the mechanical gripper 22 can perform vertical lifting movement together with the manipulator mounting base 214. A spring 215 is sleeved outside the vertical shaft 213, and the manipulator mounting base 214 presses on the spring 215. The spring 215 plays a role in lifting the manipulator mounting base 214. In the case of only being affected by the elastic force of the spring 215, the manipulator mounting base 214 and the mechanical gripper 22 are pushed upward to the upper limit position.

[0023] As Figure 2 and Figure 3 shown in the figure, the grinding treatment mechanism 4 includes a grinding seat 41, a motor frame 42, and a motor 43. The grinding seat 41 is fixedly installed on the motor frame 42. A bottle cap treatment cavity 411 is provided in the grinding seat 41. The diameter of the bottle cap treatment cavity 411 matches the outer diameter of the bottle cap part 71. The bottle cap part 71 can be inserted into the bottle cap treatment cavity 411. The motor 43 is fixedly installed on the motor frame 42. The output shaft of the motor 43 extends into the bottle cap treatment cavity 411 and is connected to a rotary tool holder 44. After the motor 43 is started, it can drive the rotary tool holder 44 to rotate at a high speed. A blade mounting ring 441 protrudes from the outer wall of the rotary tool holder 44. A number of grinding blades 45 are evenly installed on the blade mounting ring 441. The grinding blades 45 are installed with the cutting edges facing upward. When the rotary tool holder 44 rotates at a high speed, the grinding blades 45 also rotate at a high speed. As Figure 1As shown, with the rotation of the tooling turntable 1, the mechanical gripper 22 grabs the bottle cap part 71 and comes to the coating treatment station 12. At this time, the mechanical hand mounting base 214 is only affected by the elastic force of the spring 215, and the mechanical gripper 22 is lifted to the highest position. The bottle cap part 71 does not contact the grinding seat 41, and there is a gap in height between the bottle cap part 71 and the grinding seat 41. After the mechanical gripper 22 moves vertically downward, it can drive the bottle cap part 71 to be inserted into the bottle cap treatment cavity 411 of the grinding seat 41. The adhesion boss 712 on the bottle cap part 71 can contact the edge of the grinding blade 45. Since the motor 43 drives the grinding blade 45 to rotate at high speed, the edge of the grinding blade 45 can quickly scrape off the coating on the adhesion boss 712. The time for the bottle cap part 71 to be inserted into the grinding seat 41 is set at 2 - 3 seconds, which can ensure that the coating is effectively scraped off. After the time is up, the mechanical gripper 22 moves vertically upward, driving the bottle cap part 71 to disengage from the grinding seat 41. During the coating treatment operation, the mechanical gripper 22 always maintains the state of gripping the bottle cap part 71.

[0024] Since the mechanical gripper 22 has the need for lifting and lowering movements, as Figure 2 shown, the present utility model is designed with a pressing auxiliary mechanism 5. The pressing auxiliary mechanism 5 includes a pressing frame 51 and a pressing push cylinder 52. The pressing push cylinder 52 is vertically installed on the pressing frame 51. The piston rod end of the pressing push cylinder 52 is connected with a pressing push head 53. The pressing push head 53 is correspondingly arranged directly above the bottle cap treatment cavity 411. The telescopic movement of the piston rod of the pressing push cylinder 52 can drive the pressing push head 53 to make lifting and lowering movements. The maximum lifting height of the pressing push head 53 is higher than the highest position of the bottle cap part 71. This ensures that after the bottle cap part 71 comes to the coating treatment station 12, it is exactly in the position between the pressing push head 53 and the grinding seat 41. The pressing push cylinder 52 can drive the pressing push head 53 to descend. After the pressing push head 53 descends, it can apply a downward pressure to the bottle cap part 71 below, so that the bottle cap part 71 is inserted into the bottle cap treatment cavity 411. The adhesion boss 712 on the bottle cap part 71 can contact the edge of the high-speed rotating grinding blade 45 to complete the coating scraping operation. After the pressing push head 53 maintains the descending limit state for 2 - 3 seconds, the pressing push cylinder 52 drives the pressing push head 53 to rise. Since the bottle cap part 71 and the mechanical gripper 22 lose the downward pressure, under the elastic force of the spring 215, the bottle cap part 71 and the mechanical gripper 22 rise upward and reset. The bottle cap part 71 and the mechanical gripper 22 can be reset to the highest position again. At this time, the bottle cap part 71 is disengaged from the grinding seat 41, which does not affect the rotation of the tooling turntable 1, and the mechanical gripper 22 can drive the bottle cap part 71 to the discharging station 13.

[0025] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
