Description

Technical Field

[0001] This application relates to the field of battery cell production equipment manufacturing, and in particular to a material box loading and unloading mechanism and a cell unloading device. Background Technology

[0002] During the processing of wafers (such as silicon wafers and solar cells), wafer unloading devices are required to unload the wafers. The wafer unloading device includes a main conveyor line, an unloading mechanism, and a cassette loading and unloading mechanism. At least one side of the conveying direction of the main conveyor line is provided with a receiving area, and a cassette for receiving wafers is provided in the receiving area. When unloading wafers, the wafers are first conveyed to the unloading station by the main conveyor line. Then, the unloading mechanism moves the wafers at the unloading station to the cassette at the receiving position on the side of the main conveyor line. After the cassette is full of wafers, the cassette loading and unloading mechanism moves the full cassette to the next process and moves the empty cassette to an empty receiving position.

[0003] However, existing material box loading and unloading mechanisms are usually equipped with a receiving mechanism that can only receive one material box at a time. Therefore, the material box that is full of sheets needs to be moved away before an empty material box can be received, resulting in low material box loading and unloading efficiency. Utility Model Content

[0004] The purpose of this application is to provide a material box loading and unloading mechanism to solve the problem of low loading and unloading efficiency of existing material box loading and unloading mechanisms. Another purpose of this application is to provide a sheet unloading device including the material box loading and unloading mechanism.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] In a first aspect, this application proposes a material box loading and unloading mechanism, which includes a drive mechanism, a first carrier member, and a second carrier member, wherein:

[0007] The drive end of the drive mechanism is connected to the first and second carrier members, and the drive mechanism is configured to drive at least the first and second carrier members to lift and move synchronously.

[0008] The drive mechanism is configured to drive the first load-bearing component to receive the empty material box;

[0009] The drive mechanism is configured to drive the second carrier to remove the full material box from the suspension frame and drive the first carrier to suspend the empty material box onto the empty suspension frame.

[0010] The material box loading and unloading mechanism proposed in this application is provided with a first support member and a second support member. The first support member is used to receive empty material boxes, and the second support member is used to receive full material boxes. The first support member and the second support member are driven to lift and move synchronously through a drive mechanism. After the full material box is removed from the suspension frame by the second support member, the empty material box on the first support member can be put into the empty suspension frame nearby, which greatly improves the loading and unloading efficiency of material boxes and meets the requirements of fast-paced operation.

[0011] Optionally, the drive mechanism includes a first lateral drive component, a second lateral drive component, a lateral support, a mounting bracket, a first lifting drive component, and a second lifting drive component, wherein:

[0012] The fixed end of the second lateral drive is mounted on the drive end of the first lateral drive, and the first lateral drive is configured to drive the second lateral drive to reciprocate along the first horizontal direction.

[0013] The drive end of the second transverse drive is connected to the transverse base. The second transverse drive is configured to drive the transverse base to reciprocate along the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.

[0014] The mounting bracket is mounted on the transverse support, and the first and second bearing members are spaced apart along the second horizontal direction and are mounted on the mounting bracket in a liftable manner;

[0015] Both the first lifting drive and the second lifting drive are mounted on the mounting bracket. The drive end of the first lifting drive is connected to the first carrier, and the first lifting drive is configured to drive the first carrier to lift. The drive end of the second lifting drive is connected to the second carrier, and the second lifting drive is configured to drive the second carrier to lift.

[0016] By cooperating with the first lateral movement drive, the second lateral movement drive, the lateral movement seat, and the mounting bracket, the first and second load-bearing components are synchronously driven to move along the first and second horizontal directions. By using the first and second lifting drive components, the first and second load-bearing components are driven to lift independently, providing a drive mechanism that is simple in structure and stable and reliable in operation.

[0017] Optionally, the drive mechanism further includes a third transverse drive member, the mounting bracket being reciprocally mounted on the transverse seat in a second horizontal direction, the fixed end of the third transverse drive member being mounted on the transverse seat, the drive end of the third transverse drive member being connected to the mounting bracket, and the third transverse drive member being configured to drive the mounting bracket to reciprocate in a second horizontal direction.

[0018] The mounting bracket is driven to reciprocate along the second horizontal direction by the third transverse drive component, so as to increase the travel of the first and second carriers in the second horizontal direction. When manual handling of the material boxes on the first and second carriers is required, the first and second carriers are moved out of the machine table along the second horizontal direction to facilitate manual handling of the material boxes on the first and second carriers.

[0019] Optionally, the first lifting drive component and the second lifting drive component have the same structure. The first lifting drive component includes a motor, a driving pulley, a driven pulley, a transmission belt, a lifting plate, and several connecting rods, wherein:

[0020] The fixed end of the motor is fixedly mounted on the mounting bracket, and the drive pulley is mounted on the output shaft of the motor. The motor is configured to drive the drive pulley to rotate.

[0021] The driven pulley is rotatably mounted on the mounting bracket. The driven pulley and the driving pulley are spaced apart in the vertical direction. The transmission belt is fitted onto the driving pulley and the driven pulley.

[0022] The lifting plate is fixedly connected to the transmission belt, the bottom end of the connecting rod is fixedly connected to the lifting plate, and the top end of the connecting rod is fixedly connected to the first bearing member.

[0023] The motor drives the transmission belt to rotate through the driving pulley and the driven pulley, thereby raising and lowering the lifting plate, and in turn raising and lowering the corresponding first load-bearing component.

[0024] The first and second lifting drive components, through the cooperation of a motor, a driving pulley, a driven pulley, a transmission belt, a lifting plate, and several connecting rods, respectively drive the first and second load-bearing components to lift and lower, achieving high transmission efficiency, precise stroke control, and stable and reliable operation.

[0025] Secondly, this application proposes a sheet unloading device, which includes a main conveyor line, at least one upper suction conveying mechanism, a plurality of suspension frames, and at least one of the aforementioned material box unloading mechanisms, wherein:

[0026] At least one unloading station is provided on the conveying path of the main conveyor line, and the main conveyor line is configured to convey the sheet to the unloading station along the first horizontal direction.

[0027] Above each unloading station is an upper adsorption conveying mechanism. Several release positions are set on the conveying path of the upper adsorption conveying mechanism. A suspension frame is set at each release position. The lower end of each suspension frame is configured as a suspension box. The upper adsorption conveying mechanism is configured to adsorb the sheet at the unloading station and convey the adsorbed sheet along the second horizontal direction to the release position and then release it into the corresponding box.

[0028] The hanging frame includes several hooks, and the material box is provided with several locking posts. The hooks are configured to hook onto the locking posts at corresponding positions on the material box to suspend the material box on the hanging frame.

[0029] The material box loading and unloading mechanism is located on the side of the main conveyor line. The material box loading and unloading mechanism is configured to unload full material boxes on the hook and suspend empty material boxes on the hook.

[0030] The sheet unloading device proposed in this application, through the cooperation of the main conveyor line, the upper adsorption conveyor mechanism and the suspension frame, realizes the automatic collection of sheets conveyed on the main conveyor line into the material boxes on each suspension frame, resulting in high unloading efficiency. At the same time, after the material box unloading mechanism removes the full material box from the suspension frame through the second carrier, it can replenish the empty material box on the nearby first carrier to the empty suspension frame, thereby improving the material box unloading efficiency, and thus improving the sheet unloading efficiency, meeting the requirements of fast-paced operation.

[0031] Optionally, a material box loading and unloading mechanism is provided on both the first and second sides of the main conveyor line, and the conveying path of the upper adsorption conveying mechanism extends to the first and second sides of the main conveyor line. Several suspension frames are provided on both the first and second sides of the main conveyor line.

[0032] The material box loading and unloading mechanism located on the first side is configured to unload full material boxes on the suspension frame on the first side of the main conveyor line and suspend empty material boxes on the suspension frame;

[0033] The material box loading and unloading mechanism located on the second side is configured to unload full material boxes on the suspension frame on the second side of the main conveyor line and suspend empty material boxes on the suspension frame.

[0034] By setting up material box loading and unloading mechanisms on both sides of the main conveyor line, extending the conveying path of the upper adsorption conveyor mechanism to both sides of the main conveyor line, and setting up several hanging frames on both sides of the main conveyor line, it is possible to simultaneously unload sheet materials on both sides of the main conveyor line, and simultaneously remove full material boxes or hang empty material boxes on the hanging frames on both sides of the main conveyor line, thereby further improving the sheet unloading efficiency.

[0035] Optionally, a suspension frame is provided at the output end of the main conveyor line, and a tail material box is suspended on the suspension frame. The tail material box is configured to receive the sheet body output by the main conveyor line.

[0036] The material box loading and unloading mechanism is also configured to unload full tail boxes and suspend empty tail boxes on the suspension frame at the output end of the main conveyor line.

[0037] By installing a suspension frame with a tail material box at the output end of the main conveyor line, automatic unloading of sheet pieces that are missed during inspection, have no inspection data, or are marked on the main conveyor line is achieved; through the material box loading and unloading mechanism, automatic unloading of full tail material boxes and automatic loading of empty tail material boxes are achieved, eliminating the need for manual handling of tail material boxes and further improving the sheet unloading efficiency.

[0038] Optionally, the sheet feeding device further includes a first material box transfer line and a second material box transfer line arranged in parallel, wherein:

[0039] The first material box transfer line is configured to dock with the material box loading and unloading mechanism located on the first side to receive and transport full material boxes on the second carrier or send empty material boxes to the first carrier.

[0040] The second material box transfer line is configured to interface with the material box loading and unloading mechanism located on the second side to receive and transport full material boxes on the second carrier or to send empty material boxes to the first carrier.

[0041] By connecting the first and second material box transfer lines with the material box loading and unloading mechanisms on both sides of the main conveyor line, the synchronous flow of full and empty material boxes on both sides of the main conveyor line is realized, thereby improving the material box flow efficiency.

[0042] Optionally, the sheet feeding device further includes a first material box buffer line and a second material box buffer line spaced apart along the height direction. The first material box transfer line and the second material box transfer line are configured to be liftable to connect with the first material box buffer line and the second material box buffer line, wherein:

[0043] The first material box buffer line is configured to interface with the first material box transfer line and the second material box transfer line to receive and buffer full material boxes conveyed by the first material box transfer line and the second material box transfer line.

[0044] The second material box buffer line is configured to interface with the first material box transfer line and the second material box transfer line to transport the buffered empty material boxes to the first material box transfer line and the second material box transfer line.

[0045] By setting up a first material box buffer line, full material boxes are received from the first and second material box transfer lines and transported to the next process. By setting up a second material box buffer line, empty material boxes are buffered and transported to the first and second material box transfer lines. This separates the transport of empty and full material boxes, greatly facilitating their transport and improving efficiency. Furthermore, the first and second material box buffer lines are arranged along the height direction, resulting in a reasonable layout.

[0046] Optionally, the first and second material box buffer lines each include multiple rows of material box conveyor lines, and the first and second material box transfer lines are configured to be transversely movable to connect with different material box conveyor lines.

[0047] By setting the first and second material box buffer lines to include multiple rows of material box conveyor lines, and by lateral movement of the first and second material box transfer lines, they are able to connect with material box conveyor lines at different positions in the same row, which helps to improve the material box turnover efficiency.

[0062] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] During the processing of wafers (such as silicon wafers and solar cells), wafer unloading devices are required to unload the wafers. The wafer unloading device includes a main conveyor line, an unloading mechanism, and a cassette loading and unloading mechanism. At least one side of the conveying direction of the main conveyor line is provided with a receiving area, and a cassette for receiving wafers is provided in the receiving area. When unloading wafers, the wafers are first conveyed to the unloading station by the main conveyor line. Then, the unloading mechanism moves the wafers at the unloading station to the cassette at the receiving position on the side of the main conveyor line. After the cassette is full of wafers, the cassette loading and unloading mechanism moves the full cassette to the next process and moves the empty cassette to an empty receiving position.

[0064] However, existing material box loading and unloading mechanisms are usually equipped with a receiving mechanism that can only receive one material box at a time. Therefore, the material box that is full of sheets needs to be moved away before an empty material box can be received, resulting in low material box loading and unloading efficiency.

[0065] Therefore, in the first aspect, this application proposes a material box loading and unloading mechanism 10, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the material box loading and unloading mechanism 10 proposed in this application embodiment includes a drive mechanism 11, a first support member 12 and a second support member 13. The drive end of the drive mechanism 11 is connected to the first support member 12 and the second support member 13. The drive mechanism 11 is configured to drive the first support member 12 and the second support member 13 to lift and move synchronously. The drive mechanism 11 is configured to drive the first support member 12 to receive an empty material box. The drive mechanism 11 is configured to drive the second support member 13 to remove a full material box from the suspension frame 20 and drive the first support member 12 to suspend an empty material box on the empty suspension frame 20.

[0066] Specifically, both the first support member 12 and the second support member 13 are plate-shaped, and the bearing surfaces of both the first support member 12 and the second support member 13 are horizontal.

[0067] The specific loading and unloading process of the material box loading and unloading mechanism 10 is as follows:

[0068] The drive mechanism 11 drives the second carrier 13 to move directly below the suspension frame 20 on which the full material box is suspended. The drive mechanism 11 then drives the second carrier 13 to lift and move horizontally so that the full material box can be removed from the corresponding suspension frame 20 through the second carrier 13. After the full material box is removed, the corresponding suspension frame 20 is empty.

[0069] The drive mechanism 11 drives the first carrier 12, which holds the empty material box, to move below the empty suspension frame 20. The drive mechanism 11 then drives the first carrier 12 to lift, move horizontally, and suspend the empty material box on the empty suspension frame 20 through the first carrier 12.

[0070] As can be seen, the material box loading and unloading mechanism 10 proposed in this application is provided with a first support member 12 and a second support member 13. The first support member 12 is used to receive empty material boxes, and the second support member 13 is used to receive full material boxes. The first support member 12 and the second support member 13 are driven to lift and move independently and synchronously through the drive mechanism 11. After the full material box is removed from the suspension frame 20 by the second support member 13, the empty material box on the first support member 12 can be put into the empty suspension frame 20 nearby, which greatly improves the loading and unloading efficiency of the material boxes and meets the requirements of fast-paced operation.

[0071] Please see Figures 1 to 3 As shown, in one embodiment, the drive mechanism 11 includes a first lateral drive member 110, a second lateral drive member 111, a lateral seat 112, a mounting bracket 113, a first lifting drive member 114, and a second lifting drive member 115. The fixed end of the second lateral drive member 111 is mounted on the driving end of the first lateral drive member 110. The first lateral drive member 110 is configured to drive the second lateral drive member 111 along a first horizontal direction (…). Figure 3 The second lateral drive 111 is connected to the lateral support 112 at its drive end, and the second lateral drive 111 is configured to drive the lateral support 112 along the second horizontal direction (X direction). Figure 3The first horizontal direction is perpendicular to the second horizontal direction. The mounting bracket 113 is mounted on the transverse seat 112. The first support member 12 and the second support member 13 are spaced apart along the second horizontal direction and are mounted on the mounting bracket 113 in a liftable manner. The first lifting drive member 114 and the second lifting drive member 115 are both mounted on the mounting bracket 113. The drive end of the first lifting drive member 114 is connected to the first support member 12 and is configured to drive the first support member 12 to lift. The drive end of the second lifting drive member 115 is connected to the second support member 13 and is configured to drive the second support member 13 to lift.

[0072] Specifically, the first transverse drive 110 is a linear module extending along the first horizontal direction, and the second transverse drive 111 is a linear module extending along the second horizontal direction. The fixed end of the second transverse drive 111 is mounted on the drive end of the first transverse drive 110 through a transverse plate.

[0073] As can be seen, through the cooperation of the first transverse drive 110, the second transverse drive 111, the transverse seat 112 and the mounting bracket 113, the first carrier 12 and the second carrier 13 are synchronously driven to move along the first horizontal direction and the second horizontal direction; through the first lifting drive 114 and the second lifting drive 115, the first carrier 12 and the second carrier 13 are driven to lift independently, providing a drive mechanism 11 with a simple structure and stable and reliable operation.

[0074] In one embodiment, the drive mechanism 11 further includes a third transverse drive member 116. The mounting bracket 113 is reciprocally mounted on the transverse seat 112 in a second horizontal direction. The fixed end of the third transverse drive member 116 is mounted on the transverse seat 112, and the drive end of the third transverse drive member 116 is connected to the mounting bracket 113. The third transverse drive member 116 is configured to drive the mounting bracket 113 to reciprocate in the second horizontal direction.

[0075] Specifically, the third lateral movement drive 116 is a cylinder, and the mounting bracket 113 can be slidably mounted on the lateral movement seat 112 along the second horizontal direction through a sliding guide pair 117 composed of a linear guide rail and a slider, so as to improve the stability of the lateral movement of the mounting bracket 113 along the second horizontal direction.

[0076] As can be seen, the third transverse drive 116 drives the mounting bracket 113 to reciprocate along the second horizontal direction, thereby increasing the travel of the first carrier 12 and the second carrier 13 in the second horizontal direction. When manual handling of the material boxes on the first carrier 12 and the second carrier 13 is required, the first carrier 12 and the second carrier 13 are moved out of the machine table along the second horizontal direction, making it convenient for manual handling of the material boxes on the first carrier 12 and the second carrier 13.

[0077] In one embodiment, the first lifting drive component 114 and the second lifting drive component 115 have the same structure. The first lifting drive component 114 includes a motor 1140, a drive pulley 1141, a driven pulley 1142, a transmission belt 1143, a lifting plate 1144, and several connecting rods 1145. The fixed end of the motor 1140 is fixedly mounted on the mounting bracket 113, and the drive pulley 1141 is mounted on the output shaft of the motor 1140. The motor 1140 is configured to drive the drive pulley 1141 to rotate. The driven pulley 1142 is rotatably mounted on the mounting bracket 113. Driven pulley 1142 and driven pulley 1141 are arranged vertically at intervals. Transmission belt 1143 is fitted onto driven pulley 1142 and driven pulley 1143. Lifting plate 1144 is fixedly connected to transmission belt 1143. The bottom end of connecting rod 1145 is fixedly connected to lifting plate 1144, and the top end of connecting rod 1145 is fixedly connected to first bearing member 12. Motor 1140 drives transmission belt 1143 to rotate through driven pulley 1141 and driven pulley 1142, thereby driving lifting plate 1144 to rise and fall, and in turn driving the corresponding first bearing member 12 to rise and fall.

[0078] Specifically, the connecting rod 1145 is a smooth rod, and the mounting bracket 113 also includes a fixing plate 1146. The fixing plate 1146 is arranged between the first bearing member 12 and the lifting plate 1144. Both the fixing plate 1146 and the lifting plate 1144 are arranged horizontally. Several guide sleeves 1147 are provided on the fixing plate 1146. Each guide sleeve 1147 corresponds to a connecting rod 1145. The connecting rod 1145 can slide up and down through the corresponding guide sleeve 1147. Through the cooperation of the connecting rod 1145 and the guide sleeve 1147, the stability of the lifting plate 1144 is improved.

[0079] Specifically, the driving pulley 1141 and the driven pulley 1142 are synchronous pulleys, and the transmission belt 1143 is a synchronous belt.

[0080] As can be seen, the first lifting drive component 114 and the second lifting drive component 115, through the cooperation of the motor 1140, the driving pulley 1141, the driven pulley 1142, the transmission belt 1143, the lifting plate 1144 and several connecting rods 1145, respectively drive the first bearing component 12 and the second bearing component 13 to lift. The transmission efficiency is high, the stroke control is precise, and the operation is stable and reliable.

[0081] The material box loading and unloading mechanism 10 proposed in this application has the following advantages:

[0082] 1) After the full material box is removed from the suspension frame 20 using the second support member 13, the empty material box on the first support member 12 can be put into the empty suspension frame 20 nearby, which greatly improves the loading and unloading efficiency of the material box and meets the requirements of fast-paced operation.

[0083] 2) The third transverse drive 116 can move the first carrier 12 and the second carrier 13 out of the machine table along the second horizontal direction, so as to facilitate manual handling of the material boxes on the first carrier 12 and the second carrier 13.

[0084] 3) Both the first lifting drive component 114 and the second lifting drive component 115 adopt the drive method of motor 1140 and synchronous belt transmission pair, which has high transmission efficiency, precise stroke control and stable and reliable operation.

[0085] Secondly, this application also proposes a sheet feeding device, please refer to [link to relevant documentation]. Figure 3 , Figure 5 and Figure 6 As shown, the sheet unloading device proposed in this embodiment includes a main conveyor line 30, at least one upper adsorption conveying mechanism 40, several suspension frames 20, and at least one material box unloading mechanism 10. At least one unloading station is provided on the conveying path of the main conveyor line 30, and the main conveyor line 30 is configured to move along a first horizontal direction ( Figure 3 The sheet is conveyed to the unloading station in the X direction. Above each unloading station is an upper adsorption conveying mechanism 40. Several release positions are provided along the conveying path of the upper adsorption conveying mechanism 40. Each release position is equipped with a suspension frame 20. The lower end of each suspension frame 20 is configured as a hanging material box 50. The upper adsorption conveying mechanism 40 is configured to adsorb the sheet at the unloading station and move the adsorbed sheet along the second horizontal direction (X direction). Figure 3 After being conveyed to the release position (in the Y direction), it is released into the corresponding material box 50; the suspension frame 20 includes several hooks 21, and several locking posts 51 are provided on the material box 50. The hooks 21 are configured to hook the locking posts 51 at the corresponding positions on the material box 50 to suspend the material box 50 on the suspension frame 20; the material box loading and unloading mechanism 10 is provided on the side of the main conveyor line 40. The material box loading and unloading mechanism 10 is configured to unload the full material box on the hook 21 and suspend the empty material box on the hook 21. As can be seen, the sheet unloading device proposed in this application, through the cooperation of the main conveyor line 30, the upper adsorption conveying mechanism 40 and the suspension frame 20, realizes the automatic collection of the sheets conveyed on the main conveyor line 30 into the material boxes 50 on each suspension frame 20, resulting in high unloading efficiency. At the same time, after the material box unloading mechanism 10 removes the full material box from the suspension frame 20 through the second bearing member 13, it can fill the empty material box on the first bearing member 12 into the empty suspension frame 20 nearby, thereby improving the material box unloading efficiency and thus improving the sheet unloading efficiency, meeting the requirements of fast-paced operation.

[0086] Please see Figures 3 to 5As shown, in one embodiment, the upper adsorption conveying mechanism 40 includes two upper adsorption conveying components 41. The main conveying line 30 includes a first conveying line 31 and a second conveying line 32 arranged in parallel. The first conveying line 31 and the second conveying line 32 are configured to simultaneously convey the sheet along a first horizontal direction. Each upper adsorption conveying component 41 includes a pick-up adsorption conveying line 410 and a discharge adsorption conveying line 411. The two pick-up adsorption conveying lines 410 are respectively arranged directly above the discharge station of the first conveying line 31 and the second conveying line 32. The two discharge adsorption conveying lines 410... 11 are respectively set on the first and second sides of the main conveyor line 30. The two pick-up adsorption conveyor lines 410 are configured to simultaneously adsorb the sheet at the corresponding unloading station and reverse the direction to convey the sheet to the corresponding unloading adsorption conveyor line 411. The conveying directions of the two unloading adsorption conveyor lines 411 are opposite. Several release positions are set on the conveying path of each unloading adsorption conveyor line 411. The unloading adsorption conveyor line 411 is configured to adsorb the sheet conveyed by the corresponding pick-up adsorption conveyor line 410 and release the adsorbed sheet into the material box 50 after conveying it to any release position.

[0087] It can be seen that by setting the main conveying line 30 to include a first conveying line 31 and a second conveying line 32, and setting the upper adsorption conveying mechanism 40 to include two upper adsorption conveying components 41, one of the upper adsorption conveying components 41 adsorbs and conveys the sheet on the first conveying line 31, while the other upper adsorption conveying component 41 adsorbs and conveys the sheet on the second conveying line 32, thereby improving the conveying efficiency of the sheet.

[0088] In one embodiment, a material box loading / unloading mechanism 10 is provided on both the first and second sides of the main conveyor line 30. The conveying path of the upper adsorption conveying mechanism 40 extends to the first and second sides of the main conveyor line 30. A plurality of suspension frames 20 are provided on both the first and second sides of the main conveyor line 30. The material box loading / unloading mechanism 10 located on the first side is configured to unload full material boxes on the suspension frames 20 on the first side of the main conveyor line 30 and suspend empty material boxes on the suspension frames 20. The material box loading / unloading mechanism 10 located on the second side is configured to unload full material boxes on the suspension frames 20 on the second side of the main conveyor line 30 and suspend empty material boxes on the suspension frames 20.

[0089] As can be seen, by setting up material box loading and unloading mechanisms 10 on both sides of the main conveyor line 30, extending the conveying path of the upper adsorption conveying mechanism 40 to both sides of the main conveyor line 30, and setting up several hanging frames 20 on both sides of the main conveyor line 30, it is possible to simultaneously unload sheet materials on both sides of the main conveyor line 30, and simultaneously remove full material boxes or hang empty material boxes on both sides of the hanging frames 20 of the main conveyor line 30, thereby further improving the sheet unloading efficiency.

[0090] In one implementation, a suspension frame 20 is provided at the output end of the main conveyor line 30, and a tail material box 52 is suspended on the suspension frame 20. The tail material box 52 is configured to receive the sheet output by the main conveyor line 30. The material box loading and unloading mechanism 10 is also configured to unload the full tail material box 52 and suspend the empty tail material box 52 on the suspension frame 20 at the output end of the main conveyor line 30.

[0091] Specifically, both the output ends of the first conveyor line 31 and the second conveyor line 32 are equipped with a suspension frame 20, on which a tail material box 52 is suspended.

[0092] As can be seen, by setting a suspension frame 20 with a tail material box 52 at the output end of the main conveyor line 30, automatic unloading of the missing sheet, sheet without detection data, or other marked sheet on the main conveyor line 30 is realized; through the material box loading and unloading mechanism 10, automatic unloading of the full tail material box 52 and automatic loading of the empty tail material box 52 are realized, without the need for manual handling of the tail material box 52, further improving the sheet unloading efficiency.

[0093] Please see Figure 2 and Figure 3 As shown, in one embodiment, the sheet unloading device further includes a first material box transfer line 60 and a second material box transfer line 61 arranged in parallel. The first material box transfer line 60 is configured to dock with the material box loading and unloading mechanism 10 located on the first side to receive and transport full material boxes on the second carrier 13 or to send empty material boxes to the first carrier 12. The second material box transfer line 61 is configured to dock with the material box loading and unloading mechanism 10 located on the second side to receive and transport full material boxes on the second carrier 13 or to send empty material boxes to the first carrier 12.

[0094] It can be seen that by connecting the first material box transfer line 60 and the second material box transfer line 61 to the material box loading and unloading mechanisms 10 on both sides of the main conveyor line 30 respectively, the full and empty material boxes of the material box loading and unloading mechanisms 10 on both sides of the main conveyor line 30 are synchronously transferred, thereby improving the material box transfer efficiency.

[0095] In one embodiment, the sheet unloading device further includes a first material box buffer line 62 and a second material box buffer line 63 spaced apart along the height direction. The first material box transfer line 60 and the second material box transfer line 61 are configured to be liftable to connect with the first material box buffer line 62 and the second material box buffer line 63. The first material box buffer line 62 is configured to connect with the first material box transfer line 60 and the second material box transfer line 61 to receive and buffer full material boxes conveyed by the first material box transfer line 60 and the second material box transfer line 61. The second material box buffer line 63 is configured to connect with the first material box transfer line 60 and the second material box transfer line 61 to convey buffered empty material boxes to the first material box transfer line 60 and the second material box transfer line 61.

[0096] Furthermore, the first and second material box buffer lines each include multiple rows of material box conveyor lines, and the first and second material box transfer lines are configured to be laterally movable to connect with different material box conveyor lines.

[0097] Please see Figure 7 As shown, in one embodiment, the first material box transfer line 60 and the second material box transfer line 61 are installed side by side on the lifting platform 65 of the scissor lift 64 to realize the lifting of the first material box transfer line 60 and the second material box transfer line 61. A linear module 66 and two parallel linear guide rails 67 can be installed on the lifting platform 65 of the scissor lift 64 so that the linear module 66 can drive the first material box transfer line 60 and the second material box transfer line 61 to move laterally along the two linear guide rails 67 at the same time. Alternatively, two linear modules 66 and at least two parallel linear guide rails 67 can be installed on the lifting platform 65 of the scissor lift 64 so that the two linear modules 66 can drive the first material box transfer line 60 and the second material box transfer line 61 to move laterally along their respective linear guide rails 67. The first material box buffer line 62 and the second material box buffer line 63 each include multiple rows of material box conveyor lines. The lateral movement of the first material box transfer line 60 and the second material box transfer line 61 can be controlled by the linear module 66 to connect the first material box transfer line 60 and the second material box transfer line 61 to material box conveyor lines at different positions in the same row. The first material box buffer line 62 and the second material box buffer line 63 are arranged at intervals along the height direction. The lifting and lowering of the first material box transfer line 60 and the second material box transfer line 61 can be controlled by the scissor lift 64 to connect the first material box buffer line 62 and the second material box buffer line 63 at different heights.

[0098] Of course, the driving component that drives the first material box transfer line 60 and the second material box transfer line 61 to move laterally can also be a cylinder.

[0099] As can be seen, by setting up the first material box buffer line 62, it is possible to receive full material boxes conveyed by the first material box transfer line 60 and the second material box transfer line 61, and then transport the received full material boxes to the next process. By setting up the second material box buffer line 63, it is possible to buffer empty material boxes and then transport the buffered empty material boxes to the first material box transfer line 60 and the second material box transfer line 61, thus transporting empty and full material boxes in layers, which greatly facilitates the transport of empty and full material boxes and improves the transport efficiency. At the same time, the first and second material box buffer lines 62 are arranged along the height direction, which is a reasonable layout. The first and second material box buffer lines 62 and 63 are usually connected to AGV carts, which provide empty material boxes to the second material box buffer line 63 and remove the full material boxes from the first material box buffer line 62.

[0100] Please see Figure 3 and Figure 5As shown, the general workflow of the sheet unloading device of this application is as follows: The AGV provides empty material boxes to the second material box buffer line 63. The second material box buffer line 63 transports the empty material boxes toward the first material box transfer line 60 and the second material box transfer line 61. The first material box transfer line 60 and the second material box transfer line 61 receive and transport the empty material boxes transported from the second material box buffer line 63. The two material box loading and unloading mechanisms 10 move to the ends of the first material box transfer line 60 and the second material box transfer line 61, respectively, and control one of the material box loading and unloading mechanisms 10. The first support member 12 rises and lifts the empty boxes on the first material box transfer line 60, transferring the empty boxes on the first material box transfer line 60 to the first support member 12 in one of the material box loading / unloading mechanisms 10. Simultaneously, the first support member 12 in the other material box loading / unloading mechanism 10 is controlled to rise and lift the empty boxes on the second material box transfer line 61, transferring the empty boxes on the second material box transfer line 61 to the first support member 12 in the other material box loading / unloading mechanism 10. The two material box loading / unloading mechanisms 10 move along the X and Y directions... Moving to below the target full box, the loading / unloading mechanism 10 controls the second support member 13 to rise to lift the full box on the hook 21, then controls the second support member 13 to move along the Y direction, so that the full box is disengaged from the hook 21, then controls the second support member 13 to descend, so that the full box is below the hook 21, so that the loading / unloading mechanism 10 can move the full box below the hook 21. Then, the first support member 12 is controlled to perform a series of actions such as lateral movement, rising, and falling, so as to suspend the empty box on the first support member 12 in the empty space. The hook 21 continues to collect materials. Then, the two material box loading and unloading mechanisms 10 move simultaneously to the ends of the first material box transfer line 60 and the second material box transfer line 61. The two material box loading and unloading mechanisms 10 place the full boxes on their respective second carriers 13 to the ends of the first material box transfer line 60 and the second material box transfer line 61. The full boxes are transferred to the first material box buffer line 62 via the first material box transfer line 60 and the second material box transfer line 61. The first material box buffer line 62 then transfers the full boxes to the AGV trolley, which then transports the full boxes away.

[0101] Please see Figures 2 to 5 As shown, the sheet feeding device proposed in this application has the following advantages:

[0102] 1) The sheet conveyed on the main conveyor line 30 is automatically collected into the material box 50 on each suspension frame 20, which is highly efficient. After the material box loading and unloading mechanism 10 removes the full material box from the suspension frame 20 through the second bearing member 13, the empty material box on the first bearing member 12 can be put into the empty suspension frame 20 nearby, which improves the loading and unloading efficiency of the material box, thereby improving the unloading efficiency of the sheet and meeting the requirements of fast-paced operation.

[0103] 2) The two upper adsorption and conveying components 41 simultaneously adsorb and convey the sheet on the first conveying line 31 and the second conveying line 32, which improves the conveying efficiency of the sheet and thus improves the unloading efficiency of the sheet.

[0104] 3) It can simultaneously unload sheet materials on both sides of the main conveyor line 30, and simultaneously remove full material boxes or hang empty material boxes on both sides of the main conveyor line 30, further improving the sheet material unloading efficiency.

[0105] 4) Through the cooperation of the first material box transfer line 60, the second material box transfer line 61, the first material box buffer line 62 and the second material box buffer line 63, the efficient and rapid transfer of empty and full material boxes is achieved.
