[0003] At present, in the production and processing process of devices such as electronic atomization devices, most of the materials related to production and processing are concentrated and stacked or placed in large containers such as boxes or bags. Even in some working conditions where there are trays or similar material transfer carriers that can hold a certain amount of materials, the trays and other carriers still need to be concentrated and stacked in large containers such as boxes.

[0014] Preferably, the bottom of the empty-tray storage bin has a tray-storing opening for the tray to pass through from bottom to top. The tray-storing mechanism includes a tray-storing support plate arranged opposite to the lower part of the tray-storing opening and a tray-storing driving device capable of driving the tray-storing support plate to reciprocate up and down in the vertical direction.

[0015] Preferably, an empty-tray support and limit mechanism adapted to the tray-storing opening is provided at the bottom of the empty-tray storage bin.

[0022] Compared with the above-mentioned background art, in the working process of the material conveying equipment provided by the present utility model, each tray filled with materials is stacked vertically and stored in the full-material storage bin. When the downstream workstation needs to perform a material taking operation, the tray taking mechanism takes out one of the trays located in the full-material storage bin and transfers it to the feeding device.

Then, the manipulator or other material taking devices at the downstream workstation can take the materials on the tray at the positioning and material taking mechanism to meet the corresponding workstation operation requirements. After the materials on the tray at the positioning and material taking mechanism are taken out, the feeding device transports the empty tray from the positioning and material taking mechanism to the tray storage mechanism, and then the tray storage mechanism sends the empty tray into the empty-tray storage bin.

[0043] Please refer to Figures 1 to 5 。

[0044] In a specific embodiment, the material conveying device provided by the present utility model includes a pipeline mechanism 11 and a plurality of trays 20 capable of carrying materials. Above the pipeline mechanism 11, there are arranged in sequence along the material conveying direction a full tray storage mechanism 12, a positioning and picking mechanism 13, and an empty tray storage mechanism 14 that can respectively carry the trays 20.

[0045] The pipeline mechanism 11 includes a feeding device capable of transporting the tray 20 in the horizontal direction. The full tray storage mechanism 12 includes a full material storage bin 121 capable of accommodating the tray 20 and a tray picking mechanism capable of taking out the tray 20 located in the full material storage bin 121 and transferring it onto the feeding device. The empty tray storage mechanism 14 includes an empty tray storage bin 141 capable of accommodating the tray 20 and a tray storing mechanism capable of sending the tray 20 located on the feeding device into the empty tray storage bin 141.

[0046] In the specific working process, the trays 20 filled with materials are stacked vertically and stored in the full material storage bin 121. When the downstream station needs to perform a picking operation, the tray picking mechanism takes out one of the trays 20 located in the full material storage bin 121 and transfers it onto the feeding device. The feeding device transports the tray 20 to the positioning and picking mechanism 13, and then the manipulator or other material picking devices at the downstream station can pick the materials on the tray 20 at the positioning and picking mechanism 13 to meet the corresponding station operation requirements. After the materials on the tray 20 are picked at the positioning and picking mechanism 13, the feeding device transports the empty tray 20 from the positioning and picking mechanism 13 to the tray storing mechanism, and then the tray storing mechanism sends the empty tray 20 into the empty tray storage bin 141.

[0047] During this period, in coordination with the material taking requirements at the downstream workstations, the tray taking mechanism, the feeding device, and the tray storing mechanism can be cycled in sequence, so as to send the trays 20 in the full material storage bin 121 to the positioning material taking mechanism 13 one by one to complete material taking, and then send the empty trays 20 after material taking to the empty tray storage bin 141 for centralized stacking storage until the trays 20 in the full material storage bin 121 are all taken, or the empty trays 20 in the empty tray storage bin 141 are stacked in excess, or the material taking operation at the downstream workstations is completed. Then, an appropriate amount of trays 20 filled with materials can be stored in the full material storage bin 121, and the empty trays 20 stacked in the empty tray storage bin 141 can be centrally taken out to meet the requirements of subsequent material conveying process operations.

[0048] Through the coordinated cooperation and cyclic operation of the full tray storage mechanism 12, the positioning material taking mechanism 13, and the empty tray storage mechanism 14, the material conveying equipment realizes the efficient taking, conveying, and stacking of the trays 20, improves the corresponding material taking and conveying efficiency, and the entire material conveying process is fully coordinated by each action mechanism without manual intervention by staff, greatly improving the operation accuracy and operation efficiency of the entire material conveying process, effectively avoiding damage to the materials during conveying and stacking, reducing the loss of materials during storage and transportation, and improving the material utilization rate.

[0049] Generally, in actual working conditions, an upper computer and a lower computer communicatively connected to each action mechanism of the material conveying equipment are also equipped, and the upper computer and the lower computer are also communicatively connected to accurately and flexibly control the overall working operation process of the material conveying equipment.

[0050] In specific applications, the upper computer is generally an electronic computer capable of overall control and management of the overall working conditions and operating states of the material conveying equipment; while the lower computer usually selects a PLC (programmable logic controller) or a single-chip microcomputer that can be respectively adapted to the corresponding action mechanisms such as the full tray storage mechanism 12, the positioning material taking mechanism 13, the empty tray storage mechanism 14, and the assembly line mechanism 11, and the state of each single-chip microcomputer or PLC is monitored and its operation is managed through the electronic computer serving as the upper computer, so as to flexibly adjust and control the specific working state of the material conveying equipment and the operating modes of each action mechanism according to actual working condition requirements to ensure the corresponding working condition requirements.

[0051] In addition, in order to further improve the working condition adaptability and use convenience of the material conveying equipment in actual applications, each full-disk storage mechanism 12, positioning and material-taking mechanism 13, empty-disk storage mechanism 14, and assembly line mechanism 11 and other functional mechanisms can be integrally arranged on the same operating platform 10, and traveling mechanisms such as universal wheels can be arranged at the bottom of the operating platform 10. Thus, by moving the operating platform 10 to the target position, the overall movement of the material conveying equipment and the station layout can be realized. Correspondingly, telescopic legs that can be vertically telescoped and are in reliable contact with the ground can also be arranged at the bottom of the operating platform 10, so that after the operating platform 10 is moved to the target station, the telescopic legs can be extended and abutted against the ground, thereby lifting the operating platform 10 and the material conveying equipment located on the operating platform 10 as a whole, so as to prevent the equipment from moving during operation and ensure the smooth and controllable flow of the corresponding electronic cigarette shell assembly process.

[0052] Specifically, the assembly line mechanism 11 includes two feeding brackets 111 arranged in parallel in the horizontal direction. The feeding devices are pulley devices 112 arranged in one-to-one correspondence on the feeding brackets 111 and symmetrically arranged in the horizontal direction. The two pulley devices 112 are arranged in parallel in the horizontal direction and are in clearance fit to form a positioning gap 113 between the two pulley devices 112. The width of the positioning gap 113 is smaller than the width of the material tray 20. The full-material storage bin 121 and the empty-disk storage bin 141 are both fixed to the tops of the two feeding brackets 111. The material-taking mechanism and the disk-storing mechanism are both arranged in the positioning gap 113.

[0053] It should be noted that the material tray 20 is usually a plate-shaped member with a plurality of material slots in the middle for storing materials, and the edge part of the material tray 20 is a plate-shaped member with a smooth extension structure, which is used as the force-bearing contact part when cooperating with the action ends of other supporting mechanisms or transfer mechanisms. On this basis, designing the width of the positioning gap 113 to be slightly smaller than the width of the material tray 20 can enable the material-taking mechanism to take out the material tray 20 from the full-material storage bin 121, and only need to place the material tray 20 in the centered position and make the material tray 20 contact the pulleys of the pulley device 112, then the circulating rotation of the pulleys can drive the material tray 20 to move synchronously to downstream workstations such as the positioning and material-taking mechanism 13 and subsequent disk-storing mechanisms, effectively ensuring the structural stability and moving efficiency of the material tray 20 when moving with the pulley device 112, further avoiding the scattering or damage of the materials on the material tray 20 during transportation, and correspondingly improving the material conveying efficiency.

[0054] It is not difficult to understand that the structure of the pulley device 112 is simple and reliable, and the operation is stable and controllable. On this basis, the disc taking mechanism and the disc storing mechanism are arranged in the positioning gap 113, which can further improve the assembly space utilization and component integration of the material conveying equipment, optimize its overall equipment structure, and effectively avoid structural interference between the moving parts of the disc taking mechanism and the disc storing mechanism and the operating space of the pulley device 112, thereby ensuring the smooth operation of the assembly line mechanism 11 and the efficient transportation of materials.

[0055] In actual assembly applications, the pulley device 112 can be replaced by a worm gear mechanism or a gear rack structure that can achieve reciprocating movement and cyclic operation as the specific application type of the feeding device. Considering the optimal operating requirements under normal working conditions, it is advisable to use a feeding device that can achieve step-by-step movement. Of course, the staff can also flexibly select and adjust the specific type of feeding device based on comprehensive consideration of factors such as actual working conditions and process costs. In principle, any type that can meet the actual application needs of the material conveying equipment is acceptable.

[0056] Specifically, the bottom of the full material storage bin 121 is provided with a tray-taking opening 122 through which the material tray 20 passes from top to bottom, and the tray-taking mechanism includes a tray-taking support plate 123 arranged below the tray-taking opening 122 and a tray-taking driving device 124 capable of driving the tray-taking support plate 123 to reciprocate and rise and fall in the vertical direction. The tray-taking opening 122 is arranged at the bottom of the full material storage bin 121, which can effectively shorten the distance between the tray-taking opening 122 and the pulley device 112, so that the movement path of the tray-taking support plate 123 during the process of taking the material tray 20 can be shortened accordingly, so that the tray-taking support plate 123 can smoothly and efficiently transfer the material tray 20 to the pulley, thereby further improving the efficiency of the material tray 20 taking action, and the material conveying efficiency can be correspondingly improved.

[0057] More specifically, the full tray storage mechanism 12 further includes a full tray support and limit mechanism, which includes a full material limit support plate 125 located at the side of the full material storage bin 121 and a full material limit driving device 126 capable of driving the full material limit support plate 125 to reciprocate in the horizontal direction. The side wall of the full material storage bin 121 is provided with a limit slot 127 arranged horizontally in alignment with the full material limit support plate 125, and the full material limit support plate 125 can be inserted into the limit slot 127 in the horizontal direction and supported on the bottom of the material tray 20.

[0058] Under normal operating conditions, the full - material limit support plate 125 is inserted into the limit slot 127, and the insertion part of the full - material limit support plate 125 supports the bottom of the lowest tray 20 in the full - material storage bin 121. In this way, the full - material limit support plate 125 is used as an auxiliary support component for each stacked tray 20 in the full - material storage bin 121. When it is necessary to take out the tray 20 in the full - material storage bin 121, the tray - taking driving device 124 drives the tray - taking support plate 123 to lift until the tray - taking support plate 123 reliably contacts and abuts against the bottom of the lowest tray 20 in the full - material storage bin 121. Then, the full - material limit support plate 125 is pulled out from the limit slot 127 under the drive of the full - material limit driving device 126, so that each stacked tray 20 in the full - material storage bin 121 is completely supported by the tray - taking support plate 123. Then, the tray - taking driving device 124 drives the tray - taking support plate 123 to descend moderately by a distance equal to the thickness of one tray 20 and then hover. After that, the full - material limit driving device 126 drives the full - material limit support plate 125 to be inserted back into the limit slot 127, and the full - material limit support plate 125 is inserted in place between the first tray 20 and the second tray 20 arranged from bottom to top, so that the full - material limit support plate 125 reliably supports the bottom of the second tray 20 arranged from bottom to top in the full - material storage bin 121. Then, the tray - taking driving device 124 drives the tray - taking support plate 123 to continue to move downward, so as to take out the lowermost tray 20 in the full - material storage bin 121 through the tray - taking opening 122 and transfer it to the pulley device 112, so that the pulley device 112 conveys the tray 20 to the positioning and material - taking mechanism 13.

[0059] Generally, in order to further optimize the support effect of the full - material limit support plate 125 on the tray 20, two full - material limit support plates 125 can be symmetrically arranged on the full - material storage bin 121, and these two full - material limit support plates 125 are respectively arranged on a set of opposite side walls of the full - material storage bin 121. During the operation, it is only necessary to ensure that the insertion and extraction actions of the two full - material limit support plates 125 are synchronized through the full - material limit driving device 126.

[0060] It should be correspondingly noted that in practical applications, the full - material storage bin 121 can be a semi - enclosed space surrounded by multiple vertically - extending guard plates arranged at the diagonal corners. There is a clearance fit between adjacent two guard plates to form a vertically - extending through - slot, and the limit slot 127 is one of the through - slots. The empty - tray storage bin 141 can also be arranged as a semi - enclosed space structure similar to the full - material storage bin 121, so as to further reduce the volume of the main structure of the material conveying equipment and the material cost, and make the component structure of the material conveying equipment more lightweight and delicate.

[0061] Correspondingly, the bottom of the empty tray storage bin 141 has a tray storage opening 142 through which the supply tray 20 can pass from bottom to top. The tray storage mechanism includes a tray storage support plate 143 arranged opposite to the lower part of the tray storage opening 142 and a tray storage driving device 144 capable of driving the tray storage support plate 143 to reciprocate vertically. Arranging the tray storage opening 142 at the bottom of the empty tray storage bin 141 can effectively shorten the distance between the tray storage opening 142 and the pulley device 112, so that the movement path of the tray storage support plate 143 during the transfer and stacking of the trays 20 can be correspondingly shortened, so that the tray storage support plate 143 can smoothly and efficiently transfer the trays 20 into the empty tray storage bin 141, thereby further improving the stacking and storage operation efficiency of the trays 20.

[0062] Furthermore, an empty tray support and limit mechanism adapted to the tray storage opening 142 is provided at the bottom of the empty tray storage bin 141. The empty tray support and limit mechanism includes an empty tray limit support plate 145 capable of extending horizontally to support the bottom of the tray 20; one end of the empty tray limit support plate 145 is hinged to the inner wall of the empty tray storage bin 141 through an empty tray limit hinge shaft 146, and the empty tray limit support plate 145 can be turned upward around the empty tray limit hinge shaft 146 so that the tray 20 can move from bottom to top above the empty tray limit support plate 145. In the normal state, the empty tray limit support plate 145 is in a horizontally extended state, so that it can act as a support component to reliably support the tray 20 located in the empty tray storage bin 141 and form a certain range of shielding for the tray storage opening 142 to prevent the tray 20 in the empty tray storage bin 141 from falling out from the tray storage opening 142. When the tray storage support plate 143 is lifted to send the empty tray 20 into the empty tray storage bin 141 from bottom to top, the tray 20 moves from bottom to top and abuts against the bottom of the empty tray limit support plate 145. As the tray storage support plate 143 continues to move upward, the tray 20 drives the empty tray limit support plate 145 to turn upward until most of the space of the tray storage opening 142 is unblocked by the empty tray limit support plate 145, so that the tray 20 can enter the empty tray storage bin 141 from the tray storage opening 142 and, driven by the lifting of the tray storage support plate 143, smoothly move above the empty tray limit support plate 145. At this time, the tray 20 has been disengaged from the abutment with the empty tray limit support plate 145, so that the empty tray limit support plate 145 can smoothly turn down and reset under its own gravity until the empty tray limit support plate 145 returns to the horizontally arranged state again, thereby forming a structural support for the tray 20 in the empty tray storage bin 141, and the tray 20 just sent into the empty tray storage bin 141 during the above operation process is at the bottom of the stacked trays 20 in the empty tray storage bin 141 and is reliably lapped on the empty tray limit support plate 145.

[0063] It is not difficult to understand that the empty tray limiting support plate 145 is in a horizontally extended state, which can be achieved by the snap connection or abutting fit between the boss-shaped limiting structure protruding on the empty tray limiting hinge shaft 146 and the empty tray limiting support plate 145, or by the snap connection or abutting fit between the boss-shaped limiting structure protruding on the inner wall of the empty tray storage bin 141 and the empty tray limiting support plate 145. In practical applications, it can be flexibly selected and adjusted according to specific working conditions and the layout of component assembly space. In principle, as long as it can ensure the stable extension and support of the empty tray limiting support plate 145 in the horizontal direction.

[0064] On this basis, there are at least two empty tray limiting support plates 145, and the empty tray limiting support plates 145 are symmetrically arranged about the geometric center of the tray storage opening 142. Considering the component operation efficiency and the utilization rate of assembly space in practical applications, it is preferable to have two empty tray limiting support plates 145, which are symmetrically arranged in the horizontal direction. Of course, in practical applications, three, four or more empty tray limiting support plates 145 can also be selected and arranged in central symmetry to further optimize the supporting effect of each empty tray limiting support plate 145 on the tray 20 and avoid local stress concentration of a single empty tray limiting support plate 145.

[0065] In addition, the positioning and material taking mechanism 13 includes a material taking support plate 131 and a material taking driving device 132 capable of driving the material taking support plate 131 to reciprocate up and down in the vertical direction, and also includes two material taking positioning frames 133, and the two material taking positioning frames 133 are fixedly arranged on the tops of the two feeding support frames 111 in a one-to-one correspondence; the two feeding support frames 111 are symmetrically arranged in the horizontal direction and are in clearance fit to form a material taking positioning groove 134 for the material taking support plate 131 to pass through in the vertical direction. After the tray 20 moves to the material taking positioning groove 134 along with the pulley device 112, the material taking support plate 131 rises under the drive of the material taking driving device 132 until it contacts the bottom of the tray 20 in the material taking positioning groove 134, and then the material taking support plate 131 continues to rise to lift the tray 20 in the material taking positioning groove 134 to be roughly level with or slightly higher than the material taking positioning frame 133, so that the corresponding material taking equipment at the station of the positioning and material taking mechanism 13 can timely take away the materials on the tray 20. After the materials are taken, the material taking driving device 132 drives the material taking support plate 131 to descend and reset, and at this time, the tray 20 on the material taking support plate 131 synchronously moves down until the tray 20 contacts the pulley again, and the empty tray 20 is driven by the pulley device 112 to move to the downstream tray storage mechanism to perform the corresponding tray storage process.

[0066] Furthermore, the positioning and material taking mechanism 13 further includes a limit stop 135 arranged between the material taking pallet 131 and the empty tray storage mechanism 14 along the material conveying direction, and a limit driving device 136 capable of driving the limit stop 135 to reciprocate vertically. After the tray 20 is transported to the material taking positioning groove 134 by the pulley device 112, the limit driving device 136 can drive the limit stop 135 to be moderately lifted to a position generally level with the feeding support 111, so that during the subsequent material taking process, the limit stop 135 is used as a lateral limiting structure for the tray 20 in the material taking positioning groove 134, avoiding the tray 20 from falling off the material taking pallet 131 or being disengaged from the material taking positioning groove 134 in the horizontal direction during the material taking process, and ensuring the accuracy and operation efficiency of the material taking operation.

[0067] It is not difficult to understand that the above-mentioned limit driving device 136 is preferably a cylinder that expands and contracts vertically, and a hydraulic cylinder or a lead screw mechanism 1244 or a link mechanism with lifting ability can also be selected. The specific device types of the tray taking driving device 124, the tray storing driving device 144, the full material limit driving device 126 or other action mechanisms that can achieve reciprocating actions mentioned in the rest of this solution can all refer to the device type of the limit driving device 136 here and will not be elaborated here. In principle, the specific application types of each driving device can be the same or different, as long as they can meet the actual application of the material conveying equipment.

[0068] Certainly, specifically in this solution, considering the assembly position of the tray taking driving device 124 and its adaptation effect with the surrounding matching structures such as the tray taking port 122, the tray taking driving device 124 is selected to be a multi-link hinge mechanism driven by a lead screw mechanism to achieve operation. Specifically, a set of sliding rails extending horizontally are arranged below the tray taking port 122, a base is slidably arranged on the sliding rails, a multi-link hinge mechanism capable of reciprocating vertically by being driven by a lead screw mechanism is arranged on the base, and the tray taking pallet 123 is linked and arranged at the top of the multi-link hinge mechanism. The lead screw mechanism is arranged horizontally on one side of the base, and the lead screw mechanism can reciprocate axially in the horizontal direction to drive the multi-link hinge mechanism to contract and extend vertically, and thereby drive the reciprocating lifting of the tray taking pallet 123. Generally speaking, the specific action principle of the tray taking driving device 124 selected in this solution is basically the same as the functional principle of the lead screw lifting table used in the machining field or the large-scale construction field, and the layout of the core functional components and the setting of the action mechanism of the two can also be directly referred to and will not be elaborated again.

[0069] In addition, position sensing modules 15 capable of adapting to the trays 20 are respectively arranged at the tops of the full - material storage bin 121 and the empty - tray storage bin 141. Generally, the position sensing module 15 can be an infrared sensing module. The position sensing module 15 can monitor in real time the stacking quantity of the trays 20 in the full - material storage bin 121 and the empty - tray storage bin 141, so as to timely inform the staff when the stacking quantity of the trays 20 in the full - material storage bin 121 or the empty - tray storage bin 141 is too high, avoiding the trays 20 from slipping out of or scattering from the corresponding storage bins, and further ensuring the safety and reliability of the material storage and transportation operations.

[0070] In summary, in the material conveying equipment provided by the present utility model, during its working operation process, the trays filled with materials are stacked vertically and placed in the full - material storage bin. When the downstream station needs to perform the material - taking operation, the tray - taking mechanism takes out one of the trays located in the full - material storage bin and transfers it to the feeding device. The feeding device transports the tray to the positioning and material - taking mechanism. Then, the manipulator or other material - taking devices at the downstream station can take the materials on the tray at the positioning and material - taking mechanism to meet the corresponding station operation requirements. After the materials on the tray at the positioning and material - taking mechanism are taken out, the feeding device transports the empty tray from the positioning and material - taking mechanism to the tray - storing mechanism, and then the tray - storing mechanism sends the empty tray into the empty - tray storage bin. During this period, in coordination with the material - taking requirements at the downstream station, the tray - taking mechanism, the feeding device, and the tray - storing mechanism can act in sequence and cyclically, so as to send the trays in the full - material storage bin to the positioning and material - taking mechanism one by one to complete the material - taking operation, and then send the empty trays after the material - taking to the empty - tray storage bin for centralized stacking and storage until the trays in the full - material storage bin are all taken out, or the empty trays stacked in the empty - tray storage bin are piled up in excess, or the material - taking operation at the downstream station is completed. Then, an appropriate amount of trays filled with materials can be stored in the full - material storage bin, and the empty trays stacked in the empty - tray storage bin can be taken out centrally to meet the requirements of subsequent material - conveying process operations. Through the coordinated cooperation and cyclic operation of the full - tray storage mechanism, the positioning and material - taking mechanism, and the empty - tray storage mechanism, the material conveying equipment realizes the efficient taking, conveying, and stacking of the trays, improves the corresponding material - taking and conveying efficiency, and the entire material - conveying process is fully coordinated by each action mechanism without manual intervention by the staff, greatly improving the operation accuracy and operation efficiency of the entire material - conveying process, effectively avoiding damage to the materials during the conveying and stacking processes, reducing the loss of materials during the storage and transportation processes, and improving the material utilization rate.

[0071] The above has introduced in detail the material conveying equipment provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea 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 modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
