Description

Technical Field

[0001] This utility model relates to an automated airtightness testing device for the nozzle of a spray can. Background Art

[0002] The rotatable injector with good sealing performance disclosed in CN207389956U includes a spray cap, a pusher, and a nozzle. The pusher has a transverse phase inlet channel and a first working chamber located at the front end of the transverse phase inlet channel. The nozzle has a rotating part hinged to the first working chamber. Several non-communicating spray holes are provided in the rotating part. When one spray hole is connected to the transverse phase inlet channel, the other spray holes are not connected to the transverse phase inlet channel, thereby realizing two different spraying modes. Previously, the applicant used manual assembly of the entire injector and inspection of the spray channel by workers. The installation efficiency was low and the labor intensity was high. Moreover, since the injector is small in size, the assembly often uses the index finger and thumb, which can easily cause crush damage to the index finger and thumb. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0020] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0021] Reference Figure 1-7An automated airtightness testing device for a spray can cap includes a spray channel testing mechanism 3. The spray channel testing mechanism 3 includes a second turntable 8 with several testing molds 7, a testing device group for testing the spray channel of the cap, and a second clamping device 10 for classifying qualified and unqualified products. The testing device group includes a first air passage testing device 9, a push rod device 24 for rotating the nozzle, a second air passage testing device 25, and an image testing device for detecting whether the nozzle is installed backwards.

[0022] This automated press-type airtightness testing device can be applied to an automated assembly line for spray can caps. The automated assembly line includes an assembly line body, which includes a press-type assembly mechanism 1, a first conveying mechanism 2, a spray channel detection mechanism 3, a second conveying mechanism 4, and a cap assembly mechanism 5. The press-type assembly mechanism 1 includes a first turntable 31 with several first assembly molds 6 and a first clamping device group for clamping parts onto the first assembly molds 6. The cap assembly mechanism 5 includes a third turntable 12 with several second assembly molds 11, a third clamping device 13 for clamping parts onto the second assembly molds 11, and a fourth clamping device 14 for clamping the finished caps away. By adopting fully automated assembly and testing, it can effectively improve production efficiency and quality, and reduce the labor intensity of workers.

[0023] The press head assembly mechanism 1 further includes a first vibrating plate 15 for transporting the press head, a second vibrating plate 16 for transporting the nozzle, a third vibrating plate 17 for transporting the sealing gasket, and corresponding transport tracks. The first clamping device group includes a first press head clamping device 18 for mounting the press head on the first assembly mold 6, a first sealing gasket clamping device 19 for mounting the sealing gasket inside the press head, and a first nozzle clamping device 20 for mounting the nozzle on the press head.

[0024] The first press head clamping device 18 is installed at the front end of the transport track of the first vibrating plate 15, the first sealing gasket clamping device 19 is installed at the front end of the transport track of the third vibrating plate 17, and the first nozzle clamping device 20 is installed at the front end of the transport track of the second vibrating plate 16.

[0025] The first press head clamping device 18 includes a first press head mounting base, a first press head sliding base that can move left and right is mounted on the first press head mounting base, a first press head clamping base that can move back and forth is mounted on the first press head sliding base, and a first press head clamping claw that can move up and down is mounted on the first press head clamping base.

[0026] The first gasket clamping device 19 includes a first gasket mounting base, a first gasket sliding base that can move left and right is mounted on the first gasket mounting base, a first gasket clamping base that can move back and forth is mounted on the first gasket sliding base, and a first gasket insert that can move up and down is mounted on the first gasket clamping base.

[0027] The first nozzle clamping device 20 includes a first nozzle mounting base, a first nozzle sliding base that can move left and right is mounted on the first nozzle mounting base, a first nozzle clamping base that can move back and forth is mounted on the first nozzle sliding base, and a first nozzle clamping claw that can move up and down is mounted on the first nozzle clamping base.

[0028] The first conveying mechanism 2 includes a second press head clamping device 21, a first conveyor belt 22, and a third press head clamping device 23.

[0029] The first press head gripper, the first sealing gasket pin, and the first nozzle gripper can all move in six directions. The press head in the first vibrating plate 15, the nozzle in the second vibrating plate 16, and the sealing gasket in the third vibrating plate 17 are transported to the front end of the corresponding transport track by vibration. They are then gripped by the first press head gripper and placed in the first assembly mold 6. The first turntable 31 rotates, causing the first assembly mold 6 to rotate to the position of the first sealing gasket pin. The first sealing gasket pin is inserted into the center of the sealing gasket (the center of the sealing gasket has a through hole, which is part of the liquid outlet channel), and moved and placed inside the press head. The first turntable 31 rotates again, causing the first assembly mold 6 to rotate to the position of the first sealing gasket pin. The mold 6 rotates to the first nozzle clamping claw, which clamps the nozzle and mounts it on the press head. The first turntable 31 rotates again, causing the first assembly mold 6 to rotate onto the second press head clamping device 21. The press head clamping device 21 clamps the press head and places it on the first conveyor belt 22. The first conveyor belt 22 transports the press head to the third press head clamping device 23, which clamps the press head and moves it to the spray channel detection mechanism 3 for further detection. The first turntable 31 rotates again, rotating the first assembly mold 6 to the first press head clamping claw, forming a cycle.

[0030] The second press head clamping device 21 and the third press head clamping device 23 operate on the same principle as the first press head clamping device 18, and each has a second press head clamping claw and a third press head clamping claw that can move in six directions.

[0031] The nozzle on the spray cap has a front and back structure. The image detection device detects whether the nozzle is installed correctly. If it is not installed correctly, it is also a non-conforming product. The detection technology of the image detection device is existing technology.

[0032] The first airway detection device 9 includes a first airway detection device base, on which a first detection head that can move up and down is installed. The first detection head includes a first inflation detection head and a first air receiving detection head. The first inflation detection head is connected to an air pump, and the first air receiving detection head is equipped with a first sensor.

[0033] The second airway detection device 25 includes a second airway detection device base, on which a second detection head that can move up and down is installed. The second detection head includes a second inflation detection head and a second air receiving detection head. The second inflation detection head is connected to an air pump, and the second air receiving detection head is equipped with a second sensor.

[0034] The push rod device 24 includes a push rod device seat, on which a push rod sliding seat that can move back and forth toward the center of the second turntable 8 is mounted, and a push rod that can move up and down is mounted on the push rod sliding seat.

[0035] The third press head clamping claw will be installed, clamped, and placed on the detection mold 7, at which time the press head and nozzle are in a perpendicular state (e.g., Figure 7 As shown in Figure C), the second turntable 8 rotates, causing one of the detection molds 7 to rotate to the first air passage detection device 9. The first air passage detection device 9 controls the first air inlet detection head to be inserted into the liquid inlet of the press head. The first air receiving detection head abuts (or aligns) with the liquid outlet of the nozzle. Air is supplied by an air pump. Afterward, the second turntable 8 rotates again, causing the detection mold 7 to rotate to the position below the push rod. The push rod pushes the nozzle to rotate, making the press head and the nozzle parallel (as shown in Figure C). Figure 7 As shown in B), the second turntable 8 rotates again, causing the testing mold 7 to rotate to the second air passage testing device 25. The second air passage testing device 25 controls the second air-filling testing head to be inserted into the liquid inlet of the push-button. The second air-receiving testing head abuts (or aligns) with the other liquid outlet of the nozzle and delivers air through the air pump. If either the first air-receiving testing head or the second air-receiving testing head fails to detect airflow, it is a non-conforming product.

[0036] The assembly line body also includes a first collection chute for collecting defective products detected by the nozzle spray channel and a second collection chute 29 for collecting finished spray caps.

[0037] The second clamping device 10 is installed at the front end of the second conveying mechanism 4, and the fifth clamping device 26 is installed at the end of the second conveying mechanism 4.

[0038] The second clamping device 10 and the fifth clamping device 26 operate on the same principle as the first pressing head clamping device 18. They each have a second clamping claw and a fifth clamping claw that can move in six directions. The second clamping claw sorts non-conforming products into conforming products. The conforming products are placed on the second conveying mechanism 4, while the non-conforming products are collected in the first collection chute.

[0039] The spray cap assembly mechanism 5 also includes a fourth vibrating disc 27 for transporting the spray cap, a spray cap positioning mechanism 28, and a corresponding transport track.

[0040] The spray cap positioning mechanism 28 includes a boss 32 with a shape similar to the bottom of the spray cap. When the spray cap is placed on the boss 32, the spray cap will be adapted to the boss 32. During production, when the spray cap is transported to the transport track by the fourth vibrating plate 27, its general placement is already fixed (that is, if the design is that the front end of the spray cap is in front, then all the spray caps that move into the transport track will be placed with the front end in front, while the spray caps with the rear end in front cannot enter the transport track). When the third clamping device 13 clamps the spray cap, there may be a small angle deviation. By adapting to the boss 32, it is ensured that the placement of each spray cap is consistent.

[0041] The third clamping device 13 operates on the same principle as the first press head clamping device 18, and is equipped with a third clamping claw that can move in six directions. The fifth clamping claw clamps the press head and places it on the second assembly mold 11. The third turntable 12 rotates to the spray cap positioning mechanism 28. The third clamping claw pre-places the spray cap on the boss 32. The third clamping claw clamps the spray cap from the boss 32 and installs it on the press head on the second assembly mold 11.

[0042] There are two sets of third clamping claws. When the third clamping claw picks up the spray cap from the transport track and places it on the boss 32, the other third clamping claw will pick up the spray cap of the boss 32 and install it on the press head on the second assembly mold 11.

[0043] The assembly line body is equipped with an insertion mechanism 30 at the front end of the fourth clamping device 14, which inserts a plastic tube into the nozzle. When a spray cap rotates to the insertion mechanism 30, the insertion mechanism 30 inserts the plastic tube into the nozzle of the spray cap and cuts a certain length of the plastic tube. When the third turntable 12 rotates to the fourth clamping device 14, the fourth clamping device 14 places the finished spray cap at the second collection slide 29 and collects it. The insertion mechanism 30 pushing the plastic tube forward and cutting it is existing technology.

[0044] The driving devices used in this application, such as those that drive the movement of each clamping device, can be cylinders, linear motors, rotary motors with lead screw structures, etc.; those that drive the rotation of each turntable can be servo motors; and those that drive each clamping claw can be cylinders or other structures.

[0045] In this application, the coordination between the various clamping devices and turntables needs to be coordinated through a program, and such programs are conventional technologies and will not be described in detail.
