Description

Technical Field

[0001] The utility model relates to the technical field of portable gas cylinders, in particular to an aerosol cover positioning device. Background Art

[0002] A portable gas tank is a gas storage device designed for portable use. It is usually filled with flammable gases such as propane, butane, isobutane or a mixture thereof, and provides fuel for outdoor activities such as cooking, barbecue, camping, etc. It can also be used for emergency rescue such as heating and lighting. The portable gas tank is mainly composed of a tank body, a gas valve assembly and an aerosol cover. The gas valve assembly is arranged on the aerosol cover. The aerosol cover is used to seal the tank body so that when the gas valve assembly is opened, the flammable gas in the tank body can be discharged out of the tank body through the gas valve assembly. In the production process of the portable gas tank, the operator needs to rotate the aerosol cover on the tank body so that the notch on the aerosol cover is aligned with the arrow on the tank body, and then send the positioned tank body and the aerosol cover into the fixing device for fixed connection to ensure that the subsequent user can use up all the flammable gas in the portable gas tank. In the prior art, the operator needs to repeatedly rotate the aerosol cover to ensure that the notch on the aerosol cover is aligned with the arrow on the tank body. This method of positioning by the operator rotating the aerosol cover reduces the positioning speed of the aerosol cover, which is not conducive to improving the production efficiency of the portable gas tank.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] refer to Figures 1 to 4 The aerosol cover positioning device of the utility model embodiment includes:

[0040] Rack 100;

[0041] The conveying device 200 is arranged on the frame 100 and is used to convey a plurality of cans covered with aerosol caps from the back to the front;

[0042] A visual inspection device 300, which is disposed on the frame 100, and is used to perform visual inspection on the can body on the conveying device 200 and the aerosol cover on the can body, so as to detect the relative angle between the arrow on the can body and the notch on the aerosol cover;

[0043] The rotary drive device 400 is disposed on the frame 100. The rotary drive device 400 is disposed in front of the visual inspection device 300. The rotary drive device 400 is electrically connected to the visual inspection device 300. The rotary drive device 400 is used to drive the aerosol cover covered on the tank body to rotate so that the notch on the aerosol cover is aligned with the arrow on the tank body.

[0044] It is understandable that the conveying device 200 on the frame 100 can convey multiple cans covered with aerosol covers from back to front. As the can body and the aerosol cover move forward, the can body and the aerosol cover first move to the visual inspection device 300, which can perform visual inspection on the can body and the aerosol cover covered on the can body to detect the relative angle between the arrow on the can body and the notch on the aerosol cover, and transmit the detection signal to the rotary drive device 400. As the can body and the aerosol cover move forward, the aerosol cover and the can body move to the rotary drive device 400. After the rotary drive device 400 receives the detection signal of the visual inspection device 300, it can drive the aerosol cover covered on the can body to rotate according to the detection signal, so that the notch on the aerosol cover can be aligned with the arrow on the can body, thereby completing the positioning of the aerosol cover. Finally, the conveying device 200 sends the aerosol cover and the can body whose position is positioned into the fixing device for fixed connection. The aerosol cap positioning device can quickly and accurately rotate the aerosol cap, so that the aerosol cap can be accurately positioned on the tank body, thereby improving the positioning speed of the aerosol cap, and further facilitating improving the production efficiency of the portable gas tank.

[0045] It should be explained that the reference Figure 1 and Figure 2 The air valve assembly on the aerosol cover usually includes an air inlet pipe and an exhaust pipe. The exhaust pipe is arranged outside the tank body, and the air inlet pipe is arranged inside the tank body. Since the portable gas tank is usually kept horizontal during use, such as in a cassette stove, in order to ensure that the combustible gas in the horizontal portable gas tank can be fully used, the air inlet pipe is usually designed to be L-shaped. After the portable gas tank is installed on the cassette stove, the user cannot observe the position of the notch, and can only judge whether the current posture of the portable gas tank is correct by observing the direction of the arrow on the tank body. That is, when the user observes that the arrow on the tank body is not facing upward, it means that the current posture of the portable gas tank is incorrect. At this time, the portable gas tank needs to be rotated to make the arrow on the tank body face upward. Only in this state can the combustible gas in the tank body be fully used up.

[0046] refer to Figure 3 , from the top view, the air inlet pipe is on the center line of the notch on the aerosol cover. It is not difficult to understand that during the production process, if the notch on the aerosol cover cannot be aligned with the arrow, during the subsequent use of the user, even if the user adjusts the arrow on the tank body to point upwards, the lowest end of the air inlet pipe cannot be at the lowest point of the tank body cavity, which will result in the combustible gas in the tank body not being fully utilized. It can be seen from this that only by ensuring that the notch on the aerosol cover is aligned with the arrow during the production process can we ensure that when the arrow is pointing upwards, the lowest end of the air inlet pipe can be exactly at the lowest end of the tank body cavity, and that subsequent users can accurately adjust the posture of the tank body through the arrow, and that the combustible gas in the tank body can be fully utilized.

[0047] In an embodiment of the utility model, the visual inspection device 300 is arranged above the conveying device 200, and the area between the visual inspection device 300 and the conveying device 200 is used for the can body and the aerosol cover to pass through. As an embodiment of the utility model, the visual inspection device 300 includes a first camera, a second camera, an image recognition module and a processor. The rotational orientation of the can body conveyed on the conveying device 200 is within a certain range, so that the first camera can always capture the arrow on the side wall of the can body. Figure 3 , the first camera can shoot the side wall of the tank body to obtain a photo of the side wall of the tank body and the arrow, and transmit the photo to the image recognition module, which can identify the relative position coordinates of the arrow tip A. The second camera can shoot the aerosol cover covered on the tank body from top to bottom to obtain a top-down photo of the aerosol cover, and transmit the photo to the image recognition module, which can identify the relative position coordinates of the center line L1 of the aerosol cover gap and the relative position coordinates of the center point B of the aerosol cover. The processor can obtain the connecting line L2 between the arrow tip A and the center point B of the aerosol cover based on the relative position coordinates of the arrow tip A and the center point B of the aerosol cover, and then calculate the angle α between L1 and L2, α is the relative angle between the arrow on the tank body and the notch on the aerosol cover. α has positive and negative points, and the positive and negative of α can be determined by judging which side of L2 is on L1, which will not be repeated here. In the embodiment of the utility model, the notch on the aerosol cover is aligned with the arrow on the tank body, which means that the center line L1 coincides with the connecting line L2.

[0048] The processor then transmits the relative angle information to the rotation drive device 400, and the rotation drive device 400 drives the aerosol cover to rotate forward or reversely by an angle α according to the relative angle information, so that the notch on the aerosol cover is aligned with the arrow on the tank body, thereby completing the positioning of the aerosol cover. In an embodiment of the utility model, the tank body transported by the conveying device 200 is covered with an aerosol cover. At this time, the aerosol cover is only covered on the tank body and has not been fixedly connected to the tank body. After the aerosol cover is covered on the tank body, a small negative pressure will be generated in the inner cavity of the tank body, so that there is a certain resistance between the aerosol cover and the tank body, that is, during the process of the conveying device 200 transporting the tank body and the aerosol cover, the aerosol cover will not rotate relative to the tank body. Only under the external force of the rotation drive device 400, the aerosol cover will rotate relative to the tank body.

[0049] refer to Figure 4 and Figure 5The aerosol cap positioning device further includes a first arranging device 500, which is disposed on the frame 100 and is disposed behind the visual inspection device 300. The first arranging device 500 is used to arrange the multiple cans covered with aerosol caps on the conveying device 200 in an orderly interval, so that the multiple cans covered with aerosol caps are moved to the visual inspection device 300 in sequence. It can be understood that under the action of the first arranging device 500, the multiple cans covered with aerosol caps moving toward the visual inspection device 300 are arranged in an orderly interval, so that the multiple cans covered with aerosol caps can be moved to the visual inspection device 300 in sequence, and then the visual inspection device 300 can perform visual inspection on one can and aerosol cap at a time, which is conducive to ensuring the visual inspection accuracy of the visual inspection device 300.

[0050] refer to Figure 5 The first arrangement device 500 includes a first cylinder 510, the cylinder body of the first cylinder 510 is arranged on the frame 100, the piston rod of the first cylinder 510 can extend to the top of the conveying device 200, so that the piston rod of the first cylinder 510 blocks the multiple cans on the conveying device 200 that are all covered with aerosol caps from moving forward, and the piston rod of the first cylinder 510 can be away from the top of the conveying device 200, so that the multiple cans on the conveying device 200 that are all covered with aerosol caps move forward. It can be understood that the piston rod of the first cylinder 510 first extends to the top of the conveying device 200. Under the action of the conveying device 200, the multiple cans on the conveying device 200 that are all covered with aerosol caps move forward. When the frontmost can abuts against the piston rod of the first cylinder 510, the piston rod of the first cylinder 510 plays a blocking role, and at this time, the cans on the conveying device 200 stop moving forward, and the multiple cans are also close to each other. Then the piston rod of the first cylinder 510 contracts, so that the piston rod of the first cylinder 510 is away from the top of the conveying device 200. When the frontmost tank body is separated from the contact with the piston rod of the first cylinder 510, the multiple tank bodies continue to move forward. After the frontmost tank body passes through the piston rod of the first cylinder 510, the piston rod of the first cylinder 510 re-extends to the top of the conveying device 200, and the piston rod of the first cylinder 510 abuts against the next tank body, so that the remaining multiple tank bodies stop moving forward, and the frontmost tank body continues to move forward toward the direction of the visual inspection device 300 at the beginning, so that the distance between the frontmost tank body and the next tank body reaches the specified distance, and the piston rod of the first cylinder 510 moves away from the top of the conveying device 200 again. By analogy, the piston rod of the first cylinder 510 is repeatedly extended and contracted, so that the multiple tank bodies on the conveying device 200 can be arranged in an orderly interval.

[0051] refer to Figure 5Specifically, one end of the stopper 520 is connected to the piston rod of the first cylinder 510, and the outer wall of the other end of the stopper 520 gradually shrinks in the direction away from the first cylinder 510. It can be understood that the outer wall of the other end of the stopper 520 gradually shrinks in the direction away from the first cylinder 510, so that the other end of the stopper 520 has a guiding function, and then when the other end of the stopper 520 is abutted against the tank body, the stopper 520 can push the tank body to move backward, so that the stopper 520 can smoothly move to the front of the multiple tank bodies to prevent the multiple tank bodies from moving forward.

[0052] refer to Figure 4 and Figure 6 , the rotary drive device 400 includes a magnetic rotation component and a clamping component, the clamping component is used to clamp the tank body, and the magnetic rotation component is used to magnetically cover the aerosol cover on the tank body and drive the aerosol cover to rotate so that the notch on the aerosol cover is aligned with the arrow on the tank body. It can be understood that under the action of the conveying device 200 and the first arrangement device 500, the multiple tank bodies covered with aerosol covers move forward in an orderly manner at intervals. When the tank body moves to the clamping component, the clamping component clamps the tank body to prevent the tank body from rotating. Then the magnetic rotation component magnetically covers the aerosol cover on the tank body and drives the aerosol cover to rotate, so that the aerosol cover rotates at a relative angle α, and then the notch on the aerosol cover is aligned with the arrow on the tank body to complete the positioning of the aerosol cover. After the aerosol cover is positioned, the magnetic rotation component releases the magnetic attraction of the aerosol cover, and the clamping component releases the tank body, so that the tank body and the aerosol cover move forward again under the action of the conveying device 200.

[0053] refer to Figure 6 The clamping assembly includes two clamping blocks 450 and two second cylinders 440. The cylinder bodies of the two second cylinders 440 are both arranged on the frame 100. The two clamping blocks 450 are both arranged above the conveying device 200. The gap between the two clamping blocks 450 is used for the can body to pass through. The two clamping blocks 450 are respectively connected to the piston rods of the two second cylinders 440. The two second cylinders 440 can respectively drive the two clamping blocks 450 to approach each other so that the two clamping blocks 450 clamp the can body. It can be understood that when the can body moves between the two clamping blocks 450, the two second cylinders 440 drive the two clamping blocks 450 to approach each other, so that the can body is clamped by the two clamping blocks 450, which prevents the aerosol cover from rotating during the rotation of the can body and improves the accuracy of the aerosol cover positioning. After the aerosol cover is positioned, the two second cylinders 440 drive the two clamping blocks 450 to move away from each other, so that the two clamping blocks 450 release the can body.

[0054] refer to Figure 6The two clamping blocks 450 are provided with arc grooves 451 on the sides close to each other, and the two clamping blocks 450 are in contact with the tank body through the inner walls of the arc grooves 451. It can be understood that the two clamping blocks 450 are in contact with the tank body through the inner walls of the arc grooves 451, and the inner walls of the arc grooves 451 increase the contact area between the clamping blocks 450 and the tank body, thereby improving the clamping effect of the two clamping blocks 450, so that the two clamping blocks 450 can clamp the tank body more firmly, eliminating the possibility of the tank body rotating.

[0055] refer to Figure 6 The magnetic attraction rotating assembly includes a lifting drive 410, a rotating drive 420, an electromagnet 430 and a power supply module. The electromagnet 430 is arranged above the conveying device 200. The gap between the electromagnet 430 and the conveying device 200 is used for the aerosol cover and the tank body to pass through. The lifting drive 410 can drive the electromagnet 430 to descend so that the electromagnet 430 abuts against the aerosol cover covered on the tank body. The electromagnet 430 is electrically connected to the power supply module. The power supply module is used to supply power to the electromagnet 430 so that the electromagnet 430 magnetically attracts the aerosol cover. The rotating drive 420 is used to drive the electromagnet 430 to rotate so that the electromagnet 430 drives the aerosol cover to rotate. It can be understood that the electromagnet 430 is arranged above the two clamping blocks 450. When the tank body moves between the two clamping blocks 450, the two clamping blocks 450 clamp the tank body. Then the lifting drive 410 drives the electromagnet 430 to descend, so that the electromagnet 430 abuts against the aerosol cover on the tank body. Then the power supply module supplies power to the electromagnet 430, so that the electromagnet 430 acquires magnetism and magnetically attracts the aerosol cover. Then the rotating drive 420 drives the electromagnet 430 to rotate, so that the electromagnet 430 drives the aerosol cover to rotate, so that the notch on the aerosol cover is aligned with the arrow on the tank body, so as to complete the positioning of the aerosol cover.

[0056] After the aerosol cover is positioned, the power supply module is powered off, and the electromagnet 430 loses its magnetism and releases its magnetic attraction to the aerosol cover. Then the two clamping blocks 450 release the tank body, allowing the tank body and the aerosol cover to continue to move forward, and finally the lifting drive 410 drives the electromagnet 430 to rise and reset to position the next aerosol cover. In the utility model, after the aerosol cover is positioned, the power supply module will immediately pass a current flowing in the opposite direction to the electromagnet 430 after power is cut off, so that the electromagnet 430 can briefly have a reverse magnetism, so as to reduce the residual magnetism of the electromagnet 430 after power is cut off, so that the electromagnet 430 can quickly release its magnetic attraction to the aerosol cover, avoiding the electromagnet 430 from generating an upward magnetic force on the aerosol cover, thereby ensuring the connection effect between the aerosol cover and the tank body.

[0057] Specifically, the lifting drive component 410 is a lifting cylinder, the rotating drive component 420 is a motor, there are two electromagnets 430, both of which are connected to the output end of the motor, the piston rod of the lifting cylinder is connected to the motor, the motor is used to drive the two electromagnets 430 to rotate, and the lifting cylinder is used to drive the motor to rise or fall.

[0058] refer to Figure 4 and Figure 6 The aerosol cover positioning device also includes a second arranging device 600, which is arranged on the frame 100. The second arranging device 600 is arranged in front of the rotating drive device 400. The second arranging device 600 is used to make the multiple cans on the conveying device 200, which are all covered with aerosol covers, move forward in an orderly and spaced arrangement. It can be understood that after the cans and the aerosol covers leave the rotating drive device 400, under the action of the second arranging device 600, the multiple cans in front of the rotating drive device 400 can be re-spaced and orderly arranged and moved forward, so that the multiple cans can be moved to the rear fixing device, so that the fixing device can smoothly fix the aerosol cover to the can. The structure and principle of the second arranging device 600 are exactly the same as those of the first arranging device 500, and will not be further described here.

[0059] As an embodiment of the utility model, the conveying device 200 includes a conveyor belt and two lever assemblies. The conveyor belt can be rotatably arranged on the frame 100. The upper surface of the conveyor belt is used to support multiple can bodies. The rotating conveyor belt can drive the multiple can bodies to move forward. The two lever assemblies are both arranged on the frame 100. The two lever assemblies are both arranged above the conveyor belt and are respectively arranged on the left and right sides of the conveyor belt. The gap between the two lever assemblies is used for the movement of the can body. The two lever assemblies can abut against the can body to prevent the can body from tipping over during the movement, so that the can body and the aerosol cover can be smoothly moved to the visual detection device 300 and the rotary drive device 400, thereby enabling the positioning of the aerosol cover to be carried out smoothly.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention.
