Description

Technical Field

[0001] The utility model relates to the technical field of tea production equipment, in particular to a tea visual analysis and rejection device. Background Art

[0002] In the tea production process, the last step is usually to conduct visual analysis and elimination of tea leaves, that is, to visually analyze the tea leaves and eliminate tea leaves and impurities that do not meet the appearance standards. Therefore, the visual analysis and elimination device is often set at the end of the tea production line.

[0003] Existing visual analysis and rejection of tea generally includes a bracket, a conveying platform, a control system, a camera analysis system, a lifting device and an adsorption structure. The tea leaves are laid on the conveying platform. During the process of the conveying platform conveying the tea leaves forward, the camera analysis system performs photographic analysis. The control system drives the lifting device to move up and down through the analysis structure of the camera analysis system. During the descent, the adsorption structure adsorbs other foreign objects on the target position on the conveying platform except for the position of qualified young buds.

[0004] However, since the tender buds are not completely spread out on the conveying platform during transportation, and the tender buds and foreign objects are piled up in some places, the existing adsorption structure is simple in structure, and a large number of tender buds around the foreign objects may be easily adsorbed together during the adsorption process. Therefore, the rejected tea leaves have to be rejected again during the production process, thereby extending the production cycle and increasing the production cost. At the same time, repeated rejection may easily damage the qualified tender buds, which may once again increase the production cost. Utility Model Content

[0005] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a visual analysis and rejection device for tea leaves, which can reduce the number of qualified young buds mistakenly rejected during the analysis and rejection process, thereby reducing production costs.

[0006] In order to achieve the above object, the utility model is implemented through the following technical solutions: a tea visual analysis and rejection device, comprising:

[0007] It includes a bracket, a conveying platform, a control system, a camera analysis system, a lifting structure and an adsorption structure. The control system, the camera analysis system, the lifting structure and the adsorption structure are electrically connected. The lifting structure is arranged on the bracket. The adsorption structure includes a negative pressure adsorption source and an adsorption gun. The adsorption gun is arranged on the lifting structure. The lifting structure can drive the adsorption gun to lift and lower perpendicular to the conveying platform. It is characterized in that it also includes a separation structure. The separation structure includes a separation cylinder. The separation cylinder is sleeved outside the adsorption gun. When the lifting structure drives the adsorption gun to descend, the end face of the separation cylinder can be pressed against the surface of the conveying platform before the adsorption gun.

[0008] Furthermore, the separation cylinder includes a cylinder body and a flexible pad, the cylinder body is fixed on the adsorption gun, the flexible pad is arranged at the bottom end of the cylinder body, and the distance between the edge of the flexible pad close to the conveying platform and the conveying platform is greater than the distance between the end of the adsorption gun and the conveying platform.

[0009] Furthermore, the cylinder can be axially expanded and contracted when subjected to external force.

[0010] Furthermore, the cylinder body includes a plurality of sleeves, the plurality of sleeves are sequentially sleeved, and two adjacent sleeves can slide relative to each other along their axes.

[0011] Furthermore, the separation cylinder further comprises an elastic member, and the elastic member is arranged between the sleeves at two ends, and when the elastic member is in a natural state, all the sleeves are in an extended state.

[0012] Furthermore, the flexible pad is a hollow structure, and an air outlet slot communicating with the inner cavity of the flexible pad is arranged on the end surface of the flexible pad close to the conveying platform. An air pipe communicating with its inner cavity is arranged on the flexible pad, and the air pipe can be connected to a blast source.

[0013] Beneficial effects of the utility model:

[0014] When the above-mentioned tea visual analysis and rejection device is in use, the camera analysis system performs photographic analysis during the process of the conveying platform conveying the tea leaves forward. The control system uses the analysis results of the camera analysis system. When foreign matter other than qualified young buds is found, the lifting structure drives the separation cylinder and the adsorption gun to descend together. The separation cylinder is first pressed tightly against the conveying platform, and the foreign matter frame is set in the separation cylinder. Then the adsorption structure is started, and the foreign matter is attracted to the adsorption gun. Then the lifting structure drives the separation cylinder and the adsorption gun to rise together.

[0015] In this way, since the separation cylinder separates foreign matter from surrounding qualified young shoots, the number of qualified young shoots mistakenly adsorbed by the adsorption gun during the adsorption process can be reduced, thereby greatly reducing production costs.

DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0022] See also Figure 1 to Figure 2 The utility model provides a tea visual analysis and rejection device, including a bracket 100, a conveying platform 200, a control system 300, a camera analysis system 400, a lifting structure 500, an adsorption structure 600 and a separation structure 700.

[0023] Specifically, the control system 300, the video analysis system 400, the lifting structure 500 and the adsorption structure 600 are electrically connected. The lifting structure 500 is arranged on the bracket 100. The adsorption structure 600 includes a negative pressure adsorption source 610 and an adsorption gun 620. The adsorption gun 620 is arranged on the lifting structure 500. The lifting structure 500 can drive the adsorption gun 620 to rise and fall perpendicular to the conveying platform 200. The separation structure 700 includes a separation cylinder 710, and the separation cylinder 710 is sleeved outside the adsorption gun 620. When the lifting structure 500 drives the adsorption gun 620 to descend, the end face of the separation cylinder 710 can be pressed against the surface of the conveying platform 200.

[0024] During use, the conveying platform 200 conveys the tea leaves forward, the video analysis system 400 performs photographic analysis, and the control system 300 uses the analysis results of the video analysis system 400. When foreign matter other than qualified young buds is found, the lifting structure 500 drives the separation cylinder 710 and the adsorption gun 620 to descend together. The separation cylinder 710 is first pressed against the conveying platform 200, and the foreign matter is framed in the separation cylinder 710. Then the adsorption structure 600 is started, and the foreign matter is attracted to the adsorption gun 620. Then the lifting structure 500 drives the separation cylinder 710 and the adsorption gun 620 to rise together.

[0025] In this way, since the separation cylinder 710 separates the foreign matter from the surrounding qualified young sprouts, the number of qualified young sprouts mistakenly adsorbed by the adsorption gun 620 during the adsorption process can be reduced, thereby greatly reducing the production cost.

[0026] Specifically, the separation cylinder 710 includes a cylinder body 711 and a sealing gasket 712. The cylinder body 711 is sleeved and fixed on the adsorption gun 620, and the sealing gasket 712 is arranged at the bottom end of the cylinder body 711, and the distance between the edge of the sealing gasket 712 close to the conveying platform 200 and the conveying platform 200 is greater than the distance between the end of the adsorption gun 620 and the conveying platform 200.

[0027] When the separation cylinder 710 is pressed against the conveying platform 200 , the elasticity of the sealing cushion 712 can increase the contact area with the conveying platform 200 , further preventing the possibility of the sprouts entering the separation cylinder 710 from the gap between the separation cylinder 710 and the conveying platform 200 .

[0028] As a preferred embodiment, the cylinder 711 can be axially retracted by external force. When the separation cylinder 710 is pressed down, the end of the adsorption gun 620 can be closer to the conveying platform 200 by contraction, thereby improving the negative pressure adsorption effect.

[0029] Specifically, the cylinder 711 includes a plurality of sleeves, which are sequentially sleeved, and two adjacent sleeves can slide relative to each other along their axes. When subjected to axial pressure, the sleeves retract relative to each other, so that the entire cylinder 711 can be retracted.

[0030] As a more preferred embodiment, the cylinder 711 further includes an elastic member 713. The elastic member 713 is disposed between the sleeves at the two ends, and when the elastic member 713 is in a natural state, all the sleeves are in an extended state.

[0031] When in use, when the lifting structure 500 drives the separation cylinder 710 to leave the conveying platform 200, the outermost sleeve can be driven to extend outward under the action of the elastic member 713, thereby assisting the entire cylinder 711 to reset. Of course, in other embodiments, the elastic member 713 may not be used, and the sleeve can be driven to fall naturally and recover by gravity.

[0032] As another preferred embodiment, the sealing cushion 712 is a hollow structure, and the end face of the sealing cushion 712 close to the conveying platform 200 is provided with an air outlet groove 714 connected to the inner cavity of the sealing cushion 712, and the sealing cushion 712 is provided with an air outlet groove 720 connected to its inner cavity, and the air outlet groove 720 can be connected to the blower 730.

[0033] During use, when the separation cylinder 710 descends and is about to abut against the conveying platform 200, the blower 730 can be started to blow air from the air outlet slot 720 into the sealing cushion 712 and out from the air outlet slot 720, thereby blowing away the qualified young sprouts directly under the sealing cushion 712, and avoiding the qualified young sprouts being arranged between the sealing cushion 712 and the conveying platform 200, causing a gap to be formed between the sealing cushion 712 and the conveying platform 200, and then causing some qualified young sprouts to enter the separation cylinder 710 under the action of negative pressure, thereby affecting the removal effect.

[0034] It should be noted that, in a specific implementation, the blower 730 may be electrically connected to the control system 300. By controlling the start and stop of the blower 730 by the control system 300, the start and stop of the blower 730 may be more accurate.

[0035] The usage of the above tea visual analysis and rejection device is as follows:

[0036] During use, while the conveying platform 200 conveys the tea leaves forward, the video analysis system 400 performs photographic analysis. The control system 300 uses the analysis results of the video analysis system 400. When foreign matter other than qualified young buds is found, the lifting structure 500 drives the separation cylinder 710 and the adsorption gun 620 to descend together. The separation cylinder 710 is first pressed against the conveying platform 200, and the foreign matter is framed in the separation cylinder 710. Then the adsorption structure 600 is started, and the foreign matter is attracted to the adsorption gun 620. Then the lifting structure 500 drives the separation cylinder 710 and the adsorption gun 620 to rise together.

[0037] In this way, since the separation cylinder 710 separates the foreign matter from the surrounding qualified young sprouts, the number of qualified young sprouts mistakenly sucked by the adsorption gun 620 during the adsorption process can be reduced, thereby greatly reducing the production cost.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
