Abstract
Description
[Technical field]
[0001] The utility model relates to a light collection and leakage detection device for an aluminum can. [Background Technology]
[0002] In the production of standard single-piece aluminum aerosol cans, it is generally necessary to first stamp the aluminum block into an aluminum can blank, and then go through high-level trimming, cleaning, internal coating, printing, necking and other processes to form. However, aluminum cans are prone to leakage due to trauma and trachoma during the production process. Therefore, in order to ensure that the aluminum can has good sealing, it is often necessary to detect the leakage of the aluminum can.
[0003] Existing aluminum can leak detection devices generally use liquid or gas to detect aluminum can leaks. Among them, liquid leak detection determines the air tightness of the aluminum can by observing whether there are bubbles on the surface of the aluminum can. Although this method can detect the leakage of multiple aluminum cans at one time, the efficiency of leak detection of aluminum cans using liquid is low; while gas leak detection blows air into the aluminum can through the can mouth and detects the air pressure inside the can to determine the air tightness of the aluminum can. This method is difficult to judge and eliminate when there is a small leak in the aluminum can, and lacks accuracy. [Contents of the utility model]

If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one of the features.
[0022] like Figure 1-2As shown, a light collection and leakage detection device for aluminum cans includes a conveyor belt 1 for conveying aluminum cans, on which a light source assembly 2 is provided for irradiating light to the aluminum cans passing through, a light detection turntable assembly 3 arranged at one side of the light source assembly 2 for adsorbing the bottom of the aluminum can to drive the aluminum can to pass through the light source assembly 2 and put the aluminum can back to the conveyor belt 1 after passing through the light source assembly 2, a light detection assembly 4 arranged at the other side of the light source assembly 2 for collecting the internal light signal of the aluminum can to detect whether the aluminum can is leaking when the aluminum can rotates to a preset position where the opening end of the aluminum can is relatively set to the detection end, an adsorption turntable assembly 5 for adsorbing the aluminum can off the conveyor belt 1, and a transfer turntable assembly 6 for transferring the adsorbed aluminum can on the adsorption turntable assembly 5 to the light detection turntable assembly 3. Among them, the conveyor belt 1 is provided with a plurality of conveyor belt grooves 11 for placing aluminum cans; the conveyor belt 1 is provided with a first blowing component 7 for blowing the aluminum cans onto the adsorption turntable component 5 so that the adsorption turntable component 5 adsorbs the bottom of the aluminum can; the conveyor belt 1 is provided with a second blowing component 8 for blowing the leaked aluminum cans out of the conveyor belt, and a conveyor belt notch 12 is provided on the side surface of the conveyor belt 1 opposite to the second blowing component 8.
[0023] In actual use, the aluminum cans are fed from the previous station to the conveyor belt 1 and are placed on the conveyor belt groove 11 in turn and move with the conveyor belt 1; when the aluminum can moves to the position of the first blowing assembly 7, the first blowing assembly 7 blows air to the aluminum can to drive the aluminum can to move, so that the bottom of the aluminum can contacts the side of the adsorption turntable assembly 5 and is adsorbed by the adsorption turntable assembly 5, and the bottom of the aluminum can is adsorbed by the adsorption turntable assembly 5 to drive the aluminum can to rotate and separate from the conveyor belt 1; when the aluminum can rotates to the position of the transfer turntable assembly 6, the aluminum can is transferred from the adsorption turntable assembly 5 to the transfer turntable assembly 6 and rotates with the transfer turntable assembly 6; when the aluminum can rotates to the position of the optical inspection turntable assembly 3, the aluminum can is transferred from the transfer turntable assembly 6 to the optical inspection turntable assembly 3 and rotates with the optical inspection turntable assembly 3; During the rotation of component 3, the optical inspection turntable component 3 drives the aluminum can to pass through the light source component 2. When the aluminum can rotates to the preset position where the detection end of the light detection component 4 is relatively set to the opening end of the aluminum can, the light detection component 4 collects the internal light signal of the aluminum can and sends it to the host computer. The host computer determines whether the aluminum can is leaking based on the collected internal light data of the aluminum can; after the optical inspection turntable component 3 drives the aluminum can to pass through the light source component 2, the aluminum can is put back on the conveyor belt groove 11 of the conveyor belt 1 and continues to move with the conveyor belt 1. When the leaking defective aluminum can moves to the second blowing component 8, the second blowing component 8 blows air to the aluminum can to remove the aluminum can from the conveyor belt recess 12 of the conveyor belt 1, while the good aluminum can is conveyed to the next station with the conveyor belt 1, thereby realizing the aluminum can leakage detection function.
[0024] like Figure 1-2As shown, the adsorption turntable assembly 5 includes an adsorption turntable 51, and a plurality of adsorption turntable adsorption parts 52 are arranged around the edge on the side of the adsorption turntable 51 opposite to the bottom of the aluminum can for adsorbing the bottom of the aluminum can; the adsorption turntable adsorption part 52 includes an adsorption turntable groove 521 arranged on the side of the adsorption turntable 51, and at least one adsorption turntable air suction through hole 522 connected to the air suction device is arranged in the adsorption turntable groove 521. When the bottom of the aluminum can contacts the adsorption turntable adsorption part 52, the bottom of the aluminum can covers the adsorption turntable groove 521, and the vacuum pump extracts air through the adsorption turntable air suction through hole 522, so that the aluminum can is adsorbed on the adsorption turntable adsorption part 52 and falls off the conveyor belt 1 as the adsorption turntable 51 rotates.
[0025] like Figure 1-2 As shown, the transfer turntable assembly 6 includes a transfer turntable 61 and a transfer baffle 62. The outer side of the transfer turntable 61 is provided with a turntable rubber sleeve 63. The turntable rubber sleeve 63 is provided with a plurality of rubber sleeve grooves 64 arranged around the edge for clamping the aluminum can. The transfer baffle 62 is arranged between the adsorption turntable assembly 5 and the transfer turntable 61 to push and clamp the aluminum can on the adsorption turntable assembly 5 into the rubber sleeve groove 64. The rubber sleeve groove 64 can be elastically deformed to clamp the aluminum can. When the aluminum can rotates to the position of the transfer baffle 62 with the adsorption turntable 51, the transfer baffle 62 prevents the aluminum can from continuing to rotate with the adsorption turntable 51, pushes the bottom of the aluminum can out of the adsorption turntable groove 521, and transfers the aluminum can to the rubber sleeve groove 64, so that the aluminum can rotates with the transfer turntable 61.
[0026] like Figure 1-2 As shown, the optical inspection turntable assembly 3 includes an optical inspection turntable 31, and a plurality of optical inspection turntable adsorption parts 32 with surrounding edges for adsorbing the bottom of the aluminum can are provided on the side opposite to the bottom of the aluminum can of the optical inspection turntable 31; the optical inspection turntable adsorption part 32 includes a light-transmitting base 321 provided on the side of the optical inspection turntable 31, and a base groove 322 is provided on the light-transmitting base 321, and a base air suction through hole 323 connected to a fish suction device is provided in the base groove 322. Among them, the light-transmitting base 321 can allow the light source to illuminate the bottom of the aluminum can. When the aluminum can rotates to the position of the optical inspection turntable 31 with the transfer turntable 61, the bottom of the aluminum can contacts the light-transmitting base 321 of the optical inspection turntable adsorption part 32, and at this time, the bottom of the aluminum can covers the base groove 322 of the light-transmitting base 321, and at the same time, the vacuum pump extracts air through the base air suction through hole 323, so that the aluminum can is adsorbed on the light-transmitting base 321 and rotates with the optical inspection turntable 31.
[0027] like Figure 1-2As shown, the light source assembly 2 includes a first light source 21 and a second light source 22, and the light-emitting end face of the first light source 21 is arranged opposite to the light-emitting end face of the second light source 22, and a channel 23 for the aluminum can to pass through is arranged between the light-emitting end face of the first light source 21 and the light-emitting end face of the second light source 22. In the process that the light detection turntable 31 drives the aluminum can to rotate and pass through the channel 23 of the light source assembly 2, the first light source 21 and the second light source 22 work to emit light, and the light-emitting end face of the first light source 21 and the light-emitting end face of the second light source 22 illuminate the aluminum can. When the aluminum can rotates to the preset position where the detection end of the light detection assembly 4 is arranged opposite to the opening end of the aluminum can, the light detection assembly 4 collects the light signal inside the aluminum can. When there is a leakage through hole on the surface of the aluminum can, the light enters the aluminum can through the leakage. At this time, the light signal collected by the light detection assembly 4 is sent to the host computer, and the host computer compares and judges the collected real-time light data with the preset light data inside the aluminum can in the non-leakage state. At the same time, the inspection personnel can also modify the light data inside the aluminum can in the non-leakage state through the host computer.
[0028] like Figure 1-2 As shown, the first light source 21 is an L-shaped light source, and the light-emitting end surface of the first light source 21 is an L-shaped light-emitting end surface. The L-shaped light-emitting end surface is vertically arranged opposite to the light-emitting end surface of the second light source 22, so that the light source can illuminate the surface of the aluminum can to the maximum extent, thereby improving the detection accuracy.

All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
