[0060] The existing battery assembly process pipeline is divided into a production area for placing production vehicles, an operation area for operators to perform operations, and a battery slide for providing batteries. Currently, the operation process of operators is that when a production vehicle enters the production area, the operator walks from the operation area to the battery slide, then picks up a battery matching the model of the production vehicle from the battery slide, then walks back to the operation area, and then performs the operations of installing and tightening the battery. The whole process is time-consuming and laborious.

[0061] After research by the inventor, it is found that the distance the operator walks from the operation area to the battery slide and then back to the operation area is about 6 meters. Calculated according to the daily production of about 400 vehicles, the operator needs to walk about 50.4 kilometers per month, which is very labor-consuming; and the time taken for the operator to walk from the operation area to the battery slide and then back to the operation area is about 10 seconds. Also calculated according to the daily production of about 400 vehicles, the operator needs to spend about 23.3 hours per month on this process; in addition, the weight of each battery is about 10.9 kilograms. When the operator transports the battery, long-term operation is likely to cause physical fatigue and waist injuries, which is not beneficial to physical and mental health.

[0062] The main purpose of the present invention is to propose a material conveying system and a material conveying method, aiming to solve the technical problem of time-consuming and laborious existing battery installation.

[0063] Please refer to Figure 1 、 Figure 2 and Figure 5, in an embodiment of the present invention, the material conveying system 100 includes a material sliding table 1, a conveying trolley 2, a synchronization component 3, and a vehicle detection component; the material sliding table 1 includes a sliding table frame 11 and a first roller line body 12, the first roller line body 12 is arranged on the sliding table frame 11, the first roller line body 12 is relatively provided with a feeding end 1211 and a material taking end 1212 along a first direction, and the first roller line body 12 can move the material from the feeding end 1211 to the material taking end 1212; the conveying trolley 2 includes a bracket assembly 21, a driving component, and a second roller line body 23, the bracket assembly 21 includes a first bracket 211, a second bracket 212, and a third bracket 213, the second bracket 212 is movably installed on the first bracket 211; the third bracket 213 is movably installed on the second bracket 212; the driving component includes a first driving member 221 and a second driving member 222, the first driving member 221 is arranged on the first bracket 211, and the first driving member 221 is in transmission connection with the second bracket 212, so that the first driving member 221 can drive the second bracket 212 to move relative to the first bracket 211 along the first direction; the second driving member 222 is arranged on the second bracket 212, and the second driving member 222 is in transmission connection with the third bracket 213, so that the second driving member 222 can drive the third bracket 213 to move relative to the second bracket 212 along the first direction; the second roller line body 23 is arranged on the first bracket 211, the second roller line body 23 is respectively provided with a feeding end 2311 and a discharging end 2312 along the first direction, the first roller line body 12 can move the material from the material taking end 1212 to the feeding end 2311, and the feeding end 2311 is arranged higher than the discharging end 2312, so that the material can move from the feeding end 2311 to the discharging end 2312 under the action of gravity; the synchronization component 3 is arranged on the first bracket 211, and the synchronization component 3 can be connected with the production table board, so that the production table board can drive the conveying trolley 2 to move synchronously through the synchronization component 3; the vehicle detection component is used for detecting whether the vehicle to be processed reaches the synchronization position.

[0064] The technical solution of the present invention is to move the conveying trolley 2 to the material sliding table 1, so that the material taking end 1212 of the first roller line body 12 faces the feeding end 2311 of the second roller line body 23, and the material on the first roller line body 12 is moved from the material taking end 1212 to the feeding end 2311 through the first roller line body 12; since the height of the feeding end 2311 is higher than that of the discharging end 2312, the material can move from the feeding end 2311 to the discharging end 2312 under the action of gravity, thus realizing automatic material taking; when the vehicle detection component detects that the vehicle to be processed enters the synchronous position, the synchronous component 3 is connected to the production table board, so as to drive the conveying trolley 2 to move synchronously with the production table board, and the operator and the vehicle to be processed also move synchronously with the production table board; then, the first driving member 221 drives the second bracket 212 to extend relative to the first bracket 211 in the first direction, and the second driving member 222 drives the third bracket 213 to extend relative to the second bracket 212 in the first direction. Through two-stage extension, the material is sent to the working area of the operator; since the operator, the vehicle to be processed and the conveying trolley 2 all move synchronously with the production table board, the operator and the production trolley are basically in a relatively static state, which is convenient for the operator to directly take the material. The material can be the battery 200 or other parts. Taking the material as the battery 200 as an example, the time and energy spent by the operator in taking and carrying the battery 200 are saved, and the fatigue and waist injury caused by the operator carrying the battery 200 are avoided; since the production line is in a continuous running state during the process of the operator taking the battery 200 and installing the battery 200 on the vehicle to be processed, the production efficiency is effectively improved. It should be noted that after the operator takes the battery 200, the synchronous component 3 is separated from the production table board, and the first driving member 221 and the second driving member 222 respectively drive the second bracket 212 and the third bracket 213 to retract, so as to avoid interference between the second bracket 212 and the third bracket in the extended state and other operators or equipment.

[0065] It should be noted that the first driving member 221 and the second driving member 222 can be air cylinders or oil cylinders, and there is no limitation here. When both the first driving member 221 and the second driving member 222 are air cylinders, the stroke of the first driving member 221 can be 600 mm, and the stroke of the second driving member 222 is 680 mm. Through the first driving member 221 and the second driving member 222, the third bracket 213 can complete a telescopic movement distance of 1250 mm in total length to achieve cross-line operation; the first bracket 211 and the second bracket 212 can be slidably matched through a chute and a slide rail so that the first bracket 211 can move relative to the second bracket 212, or can be slidably matched through a guide shaft and a linear bearing to achieve that the first bracket 211 can move relative to the second bracket 212, and there is no limitation here either; similarly, the second bracket 212 and the third bracket 213 can be slidably matched through a chute and a slide rail or a guide shaft and a linear bearing to achieve that the second bracket 212 can move relative to the third bracket 213. Among them, the material can be the battery 200 or other components. It should also be noted that the first direction is Figure 1 the front-back direction shown in Figure 1 and the second direction is

[0066] Please refer to Figure 1 and Figure 3 . In an embodiment, the first roller conveyor 12 includes a first mounting frame 121 and a first conveying roller 122 rotatably mounted on the first mounting frame 121. The first mounting frame 121 is connected to the slide table frame 11. The first mounting frame 121 is provided with a feeding end 1211 and a material taking end 1212 along the first direction. The number of the first conveying rollers 122 is multiple, and the multiple first conveying rollers 122 are sequentially arranged at intervals along the first direction on the first mounting frame 121; at least one of the multiple first conveying rollers 122 is an electric conveying roller, and the electric conveying roller can move the material from the material taking end 1212 to the feeding end 2311; by providing the electric conveying roller, the conveying power is provided for the material located on the first roller conveyor 12. Relying on the electric conveying roller, the material can be moved from the feeding end 1211 to the material taking end 1212, and can also move the material from the material taking end 1212 to the feeding end 2311, realizing the automatic material taking of the conveying trolley 2, eliminating the manual material taking link and saving manpower.

[0067] In one embodiment, the height of the incoming material end 1211 is higher than the height of the material taking end 1212, so that the material can move from the material taking end 1212 to the feeding end 2311 under the action of gravity. By setting the height of the incoming material end 1211 to be greater than the height of the material taking end 1212, the material on the first roller line body 12 can automatically move from the incoming material end 1211 to the material taking end 1212 under the action of gravity, and can also move from the material taking end 1212 to the feeding end 2311 under the action of gravity, so as to realize automatic material taking of the conveying trolley 2, save the link of manual material taking, and save manpower.

[0068] See also Figure 3 In one embodiment, the material slide 1 also includes a material blocking assembly 13, the material blocking assembly 13 includes a material blocking driving member 131 and a material blocking member 132 that is transmission-connected to the material blocking driving member 131, the material blocking driving member 131 is connected to the slide frame 11, the material blocking member 132 includes a blocking position and a releasing position, the material blocking driving member 131 is used to drive the material blocking member 132 to rise and fall, so that the material blocking member 132 can reciprocate between the blocking position and the releasing position; when the material blocking member 132 is in the blocking position, the material blocking member 132 can block the material from leaving the first roller line body 12 from the material picking end 1212; when the material blocking member 132 is in the releasing position, the material can move from the material picking end 1212 to the feeding end 2311. By setting the material blocking component 13, when the material moves to the material taking end 1212, if the conveying trolley 2 has not moved to the material slide 1, the material blocking component 132 can be driven to rise by the material blocking driving component 131, so that the material blocking component 132 moves to the blocking position, and the material blocking component 132 located at the blocking position will abut against the material located at the material taking end 1212, thereby limiting the material from leaving the material taking end 1212, preventing the material from falling and causing damage to the material; when the conveying trolley 2 moves to the material slide 1 and is ready to take the material, the material blocking driving component 131 drives the material blocking component 132 to descend, so that the material blocking component 132 moves from the blocking position to the release position, so that the material taking end 1212 is connected with the feed end 2311, and the electric conveying roller rotates, thereby driving the material to move from the material taking end 1212 to the feed end 2311 more quickly, thereby increasing the material taking speed. It should be noted that the material blocking driving component 131 can be a cylinder or an oil cylinder without limitation. The material blocking member 132 may be a material blocking plate or a material blocking block.

[0069] See also Figure 2 and Figure 3, in one embodiment, the first roller line body 12 further includes a first roller bar 123 and a second roller bar 124. Both the first roller bar 123 and the second roller bar 124 are connected to the first mounting bracket 121. The first roller bar 123 and the second roller bar 124 are respectively arranged on both sides of the first conveying roller 122 along the axial direction of the first conveying roller 122. The first roller bar 123, the second roller bar 124 and the plurality of first conveying rollers 122 enclose a transportation channel for the material to flow through. By providing the first roller bar 123 and the second roller bar 124, the material can move more smoothly on the first roller line body 12. That is, when the material contacts the first gear bar or the second gear bar, since it is rolling friction, the frictional force is smaller compared to sliding friction. Therefore, the material can move more smoothly on the first roller line body 12. And because the first roller bar 123 and the second roller bar 124 are provided, the material located on the first roller line body 12 is restricted from falling from the edge of the line body, improving the reliability of transportation.

[0070] Please refer to Figure 3 , in one embodiment, the material slide 1 further includes a material detection member 14. The material detection member 14 is arranged on the slide frame 11 and is used to detect whether there is any material placed on the first roller line body 12. By providing the material detection member 14 to detect whether there is a battery 200 placed on the first roller line body 12, only when there is a battery 200 placed, the conveying trolley 2 will move towards the material slide 1. In addition, the material detection member 14 can also detect whether the battery 200 located on the first roller line body 12 matches the model of the vehicle to be processed, avoiding installing a battery 200 that does not match the material information onto the vehicle to be processed, ensuring the quality of the vehicle and reducing the number of rework times. Among them, the material detection member 14 can be an opposed switch or a contact switch.

[0071] Please refer to Figures 1 to 3In one embodiment, the number of the first roller line bodies 12 is multiple, and the multiple first roller line bodies 12 are arranged in sequence along the second direction, and the second direction is perpendicular to the first direction. The number of the first roller line bodies 12 is multiple, and the material detection parts 14 are consistent with the number of the first roller line bodies 12 and are set one by one, and the material blocking components 13 are consistent with the number of the first roller line bodies 12 and are set one by one; by setting multiple first roller line bodies 12, more batteries 200 can be accommodated, and batteries 200 of the same specifications can be accommodated, and batteries 200 of different specifications can be accommodated; the control module controls the material detection parts 14 to detect whether the multiple first roller line bodies 12 are placed on the battery 200 that is compatible with the vehicle to be processed according to the material information. If so, the material trolley moves to the nearest first roller line body 12 equipped with the battery 200, and then controls the corresponding material blocking driving part 131 to drive the material blocking part 132 to move from the blocking position to the release position, so that the battery 200 can be smoothly moved from the material taking end 1212 to the feeding end 2311.

[0072] See also Figure 4 According to an embodiment of the present invention, the second roller line body 23 includes a second mounting frame 231 and a second conveying roller 232 rotatably mounted on the second mounting frame 231, the second mounting frame 231 is connected to the third bracket 213, the second mounting frame 231 is provided with a feed end 2311 and a discharge end 2312 oppositely arranged along the first direction, the number of the second conveying rollers 232 is multiple, and the multiple second conveying rollers 232 are sequentially arranged on the second mounting frame 231 along the first direction; and the second roller line body 23 also includes two conveying roller strips 233, the two conveying roller strips 233 are respectively arranged on both sides of the second conveying roller 232 along the second direction, so that the two conveying roller strips 233 and the multiple conveying rollers form a conveying channel for the battery 200 to pass through, ensuring that the battery 200 can smoothly move from the feed end 2311 to the discharge end 2312. It should be noted that the second conveying rollers 232 are all unpowered rollers.

[0073] See also Figure 5 , Figure 6 and Figure 8, in one embodiment, the conveying trolley 2 further includes a roller assembly, and the roller assembly includes a load-bearing wheel 241 which is arranged at the bottom of the first bracket 211; the synchronization assembly 3 includes a synchronization driving member 31 and an abutting member 32 which is in transmission connection with the synchronization driving member 31. The synchronization driving member 31 is arranged on the first bracket 211, and the synchronization driving member 31 can drive the abutting member 32 to abut against the production platen, so that the production platen can drive the conveying trolley 2 to move synchronously along the second direction through the synchronization assembly 3, and the second direction is perpendicular to the first direction. When the vehicle enters the synchronization position, the synchronization driving member 31 drives the abutting member 32 to move downward so that the abutting member 32 abuts tightly against the production platen. Also, since the load-bearing wheel 241 is arranged at the bottom of the first bracket 211, the load-bearing wheel 241 can not only provide reliable support for the first bracket 211, but also enable the production platen to more easily drive the first bracket 211, the second bracket 212 and the third bracket 213 to move synchronously with the production platen while the abutting member 32 abuts tightly against the production platen. At this time, the operator, the vehicle to be processed and the battery 200 which is also located on the third bracket 213 are in a substantially stationary state relative to each other, so that it is convenient for the operator to take the battery 200 off the third bracket 213 and then install the battery 200 onto the vehicle to be processed. During this process, the production line keeps moving, ensuring the production efficiency. It should be noted that the synchronization driving member 31 can be a cylinder or an oil cylinder, and there is no limitation here. The abutting member 32 can be an abutting plate or an abutting block.

[0074] Please refer to Figure 8 , according to an embodiment of the present invention, the synchronization assembly 3 further includes a synchronization overload detection member 33, which is used for detecting whether an overload phenomenon occurs during the synchronous movement of the bracket assembly 21 and the production platen. If so, the synchronization is stopped to reduce the occurrence probability of equipment damage or production line accidents.

[0075] Please refer to Figure 9, in one embodiment, the material conveying system 100 further includes a reset driving assembly 4. The reset driving assembly 4 includes a driving member 41 and a walking wheel 42. The driving member 41 is disposed on the first bracket 211. The driving member 41 is in transmission connection with the walking wheel 42. The walking wheel 42 can abut against the ground. The driving member 41 can drive the walking wheel 42 to rotate so that the conveying trolley 2 moves in the second direction. When the operator finishes taking the battery 200, the synchronous driving member 31 drives the abutting member 32 to separate from the production platen. The first driving member 221 drives the second bracket 212 to reset, and the second driving member 222 drives the third bracket 213 to reset. In order to facilitate subsequent taking of the battery 200 and avoid occupying space to hinder the passage of other operators, it is necessary to move the entire conveying trolley 2 to the position in front of the battery 200 receiving slide for receiving the battery 200, that is, move it to the starting position. In this embodiment, by adding the reset driving assembly 4, when it is necessary to move to the starting position, the driving member 41 drives the walking wheel 42 to rotate so that the conveying trolley 2 moves to the starting position. When it is necessary for the battery 200 receiving slide to receive the battery 200, the driving member 41 can also drive the walking wheel 42 to rotate, so that the conveying trolley 2 moves from the starting position to the battery 200 receiving slide to receive the battery 200.

[0076] Please refer to Figure 9 , according to an embodiment of the present invention, the driving member 41 includes a lifting driving member 411 and a walking driving member 412. The lifting driving member 411 is disposed on the first bracket 211. The output end of the lifting driving member 411 is connected to the walking driving member 412. The walking driving member 412 is in transmission connection with the walking wheel 42. The walking driving member 412 can drive the walking wheel 42 to rotate. The lifting driving member 411 is used to drive the walking wheel 42 to lift through the walking driving member 412 so that the walking wheel 42 abuts against or separates from the ground. The walking wheel 42 abuts against the ground, and the walking driving member 412 can drive the walking wheel 42 to rotate so that the bracket assembly 21 moves in the second direction. When it is necessary to move to the position in front of the battery 200 receiving slide for receiving the battery 200 or move to the battery 200 receiving slide to receive the battery 200, the lifting driving member 411 drives the walking driving member 412 and the walking wheel 42 to descend together until the walking wheel 42 contacts the ground, and then the walking driving member 412 drives the walking wheel 42 to rotate to move the whole material conveying mechanism. When the bracket assembly 21 moves synchronously with the production platen, the lifting driving member 411 drives the walking wheel 42 to rise and separate from the ground to avoid the walking wheel 42 contacting the ground and affecting the synchronous operation of the bracket assembly 21 and the production platen. It should be noted that the lifting driving member 411 can be a cylinder or an oil cylinder, which is not limited herein. The walking driving member 412 can be a servo motor or a stepping motor, which is not limited herein. Taking the motor as an example, the motor can drive the walking wheel 42 to rotate through gear transmission, or drive the gear to rotate in a direct drive form.

[0077] According to an embodiment of the present invention, the lifting driving member 411 is a cylinder, the extending shaft of the cylinder is connected to the fixed frame, the traveling driving member 412 is a motor, the motor is installed on the fixed frame, and the motor can drive the traveling wheels 42 to rotate through gear transmission or directly. The fixed frame and the first bracket 211 are slidably matched through sliders and slide rails, improving the stability of the lifting of the traveling wheels 42. In addition, a descending-in-place detection switch 43 is provided on the fixed frame to detect whether the fixed frame has descended to a specified position. If so, it means that the traveling wheels 42 have contacted the ground, and this signal is used to determine whether the traveling wheels 42 have descended in place and contacted the ground.

[0078] Please refer to Figure 2 and Figure 3 , in an embodiment, the material sliding table 1 further includes a trolley detection member 15. The conveying trolley 2 includes a material taking position, and the driving member 41 can drive the traveling wheels 42 to rotate so that the conveying trolley 2 moves to or away from the material taking position; when the conveying trolley 2 is at the material taking position, the incoming material end 1211 can communicate with the feeding end 2311, and the detection member is used to detect whether the conveying trolley 2 is at the material taking position. The number of the trolley detection members 15 is the same as that of the first roller lines 12 and they are arranged in one-to-one correspondence. The control module controls the material detection member 14 to detect whether batteries 200 adapted to the vehicle to be processed are placed on the plurality of first roller lines 12 according to the material information. If so, the driving member 41 drives the traveling wheels 42 to rotate until the trolley detection member 15 detects that the material trolley moves to the first roller line 12 where the battery 200 is placed, and then controls the corresponding material blocking driving member 131 to drive the material blocking member 132 to move from the blocking position to the releasing position, so that the battery 200 can smoothly move from the incoming material end 1212 to the feeding end 2311, realizing that the conveying trolley 2 can automatically receive the battery 200 matching the vehicle to be processed according to the material information.

[0079] Please refer to Figure 5 and Figure 7 , in an embodiment, the roller assembly further includes a guide wheel 242. The guide wheel 242 is arranged at the bottom of the first bracket 211, and the guide wheel 242 is used for rolling cooperation with the track extending in the second direction. By providing the guide wheel 242 for rolling cooperation with the track, the moving direction of the first bracket 211 is guided, ensuring that the first bracket 211 can reciprocate along the second direction.

[0080] Please refer to Figure 4 and Figure 6, in one embodiment, the conveying trolley 2 further includes a loading platform 25. The loading platform 25 is arranged on the third support 213, and the discharging end 2312 is arranged towards the loading platform 25 so that the material leaving the discharging end 2312 can move to the loading platform 25. By providing the loading platform 25 to carry the material, taking the battery 200 as an example, after the battery 200 leaves the discharging end 2312, it will move onto the loading platform 25, and the loading platform 25 will carry the battery 200 for the operator to pick up.

[0081] Please refer to Figure 4 , in one embodiment, the loading platform 25 includes a platform body 251 and a baffle 252. The platform body 251 is arranged on the third support 213, the discharging end 2312 is arranged towards one end of the loading platform 25, and a baffle 252 is arranged at the other end of the loading platform 25. The baffle 252 is used to abut against the material so that the baffle 252 can limit the material moving in the first direction from leaving the platform body 251. Since the feeding end 2311 is higher than the discharging end 2312, the battery 200 leaving the discharging end 2312 has a certain initial velocity. To prevent the battery 200 from sliding off the platform body 251, a baffle 252 is provided on the platform body 251. By abutting the baffle 252 against the battery 200, the battery 200 is restricted from continuing to move in the first direction, so that the battery 200 can stay on the platform body 251 smoothly for the operator to pick up.

[0082] Please refer to Figure 4 and Figure 6 , according to an embodiment of the present invention, in one embodiment, the conveying trolley 2 further includes a battery detection member 26. The battery detection member 26 is arranged on the third support 213, and the detection end of the battery detection member 26 faces the loading platform 25. The detection member is used to detect whether there is a material placed on the loading platform 25. By providing the battery detection member 26 to detect whether there is a battery 200 placed on the loading platform 25, it is used to judge whether the battery 200 on the sliding platform has successfully moved to the loading platform 25 through the conveying slideway. The battery detection member 26 can adopt a light curtain switch or a contact switch, which is not limited herein.

[0083] Please refer to Figure 5 and Figure 6 , according to an embodiment of the present invention, a three-color lamp 27 is arranged on the support assembly 21. By providing the three-color lamp 27, it is convenient for the operator to timely grasp the equipment status information of the conveying trolley 2 according to the color of the three-color lamp 27.

[0084] Please refer to Figure 4 , according to another embodiment of the present invention, an operation completion button 28 is further arranged on the third support 213. When the operator finishes picking up the battery 200, press the operation completion button 28, and the first driving member 221 and the second driving member 222 respectively drive the second support 212 and the third support 213 to reset.

[0085] Please refer to Figure 6 and Figure 7 In an embodiment, the material conveying system 100 further includes a region scanning assembly 5. The region scanning assembly 5 includes a first region scanner 51, a second region scanner 52, and a third region scanner 53. The first region scanner 51 and the second region scanner 52 are respectively disposed on both sides of the first bracket 211 along the second direction, and the second direction is perpendicular to the first direction; the third region scanner 53 is disposed on the third bracket 213, and the detection end of the third region scanner 53 faces away from the first bracket 211. By providing the region scanning assembly 5, the safety is enhanced. The first region scanner 51 is used to detect whether an operator enters the scanning region during the process of the bracket assembly 21 moving in the direction approaching the battery 200 slide. If it is detected that the operator enters the scanning region during this process, the rotation speed of the traveling drive 412 driving the traveling wheels 42 is reduced, thereby slowing down the overall moving speed of the conveying trolley 2. When the first region scanner 51 detects that the operator is less than a preset safety distance from the first scanner, taking 200 mm as an example of the preset safety distance, the movement of the conveying trolley 2 is stopped to improve safety; similarly, the second region scanner 52 is used to detect whether an operator enters the deceleration region during the process of the bracket assembly 21 moving away from the battery 200 slide. If so, the moving speed of the conveying trolley 2 is slowed down. If the operator enters the scanning region within 200 mm, the movement of the conveying trolley 2 is stopped; similarly, during the process of the third bracket 213 moving towards the working area, when the third region scanner 53 detects an operator in the scanning region, the extending speed of the first drive 221 and the second drive 222 is slowed down. When it is detected that the operator in the scanning region is relatively close to the third bracket 213, the movement of the third bracket 213 is stopped to improve safety.

[0086] According to an embodiment of the present invention, an anti-collision bar 7 is provided on the side of the first bracket 211 facing the battery 200 slide for protecting the first bracket 211.

[0087] Please refer to Figure 4 and Figure 6 In an embodiment, the material conveying system 100 further includes a touch edge assembly 6. The touch edge assembly 6 includes a first safety touch edge 61, a second safety touch edge 62, and a third safety touch edge 63. The first safety touch edge 61 and the second safety touch edge 62 are respectively disposed on both sides of the third bracket 213 along the second direction, and the third safety touch edge 63 is disposed on the side of the third bracket 213 away from the feeding end 2311 along the first direction. By providing the first safety touch edge 61, the second safety touch edge 62, and the third safety touch edge 63 to check for collisions, when an object collides with any one of the first safety touch edge 61, the second safety touch edge 62, and the third safety touch edge 63, the conveying trolley 2 stops moving to improve safety.

[0088] Please refer to Figure 10 , Figure 10 which is a schematic flow chart of the first embodiment of the material conveying method provided by the present invention. The present invention also provides a material conveying method, which is applied to the above-mentioned material conveying system. The material conveying method includes the following steps:

[0089] S100, control the conveying trolley to move to the material sliding table;

[0090] By moving the conveying trolley to the material sliding table, the process of the operator walking to the material sliding table is omitted, saving manpower. Among them, the conveying trolley can drive the walking wheels to rotate through a motor, so as to drive the conveying trolley to move to the material sliding table, or can be connected to the production table through a synchronous component, so as to drive the conveying trolley to move to the material sliding table.

[0091] S200, control the first roller line to transport the material to the second roller line;

[0092] By transporting the material to the second roller line through the first roller line, automatic material taking from the material sliding table is realized, omitting the process of the operator taking the material from the material sliding table and saving manpower. Among them, the first roller line can be provided with electric rollers, and rely on the electric rollers to provide conveying power for the material, so that the material can smoothly move from the first roller line to the second roller line; or the first roller line can be placed obliquely, so that the height of the incoming material end is higher than the height of the material taking end, and then the material can smoothly move from the first roller line to the second roller line.

[0093] S300, control the vehicle detection component to judge whether the vehicle to be processed enters the synchronous position;

[0094] Judge whether the vehicle located on the production line enters the synchronous position through the vehicle detection component, so that the synchronous component can judge whether it needs to be connected to the production table. Among them, the vehicle detection component is fixed, and the vehicle to be processed located on the production line moves synchronously with the production table.

[0095] S310, if the vehicle to be processed enters the synchronous position, control the synchronous component to be connected to the production table; so that the conveying trolley moves synchronously with the vehicle to be processed;

[0096] If the vehicle to be processed enters the synchronous position, control the synchronous component to be connected to the production table, so that the production table can drive the conveying trolley, the vehicle to be processed and the operator to move synchronously through the synchronous component. If the vehicle to be processed does not enter the synchronous position, repeat the steps of S300.

[0097] S400 controls the first driving member to drive the second bracket to extend relative to the first bracket in the first direction, and controls the second driving member to drive the third bracket to extend relative to the second bracket in the first direction until the third bracket enters the working area;

[0098] The first driving member drives the second bracket to move in the first direction away from the first bracket, and the second driving member drives the third bracket to move in the first direction away from the second bracket, thereby realizing two-stage extension, and then transporting the battery located on the second roller line body to the working area, saving the time and effort spent by the operator in taking and transporting the battery.

[0099] S500 takes the material on the second roller line body and installs the material on the vehicle to be processed.

[0100] Since the operator, the vehicle to be processed, and the conveying trolley all move synchronously with the production platen, the operator and the production trolley are basically in a relatively static state, thus facilitating the operator to directly take the material and install the material on the vehicle to be processed.

[0101] The technical solution of the present invention is to move the conveying trolley to the material sliding table so that the material taking end of the first roller line body faces the feeding end of the second roller line body, and the material on the first roller line body is moved from the material taking end to the feeding end through the first roller line body; since the height of the feeding end is higher than the height of the discharging end, the material can move from the feeding end to the discharging end under the action of gravity, thereby realizing automatic material taking; when the vehicle detection member detects that the vehicle to be processed enters the synchronous position, the synchronous component is connected to the production platen, thereby driving the conveying trolley to move synchronously with the production platen, and the operator and the vehicle to be processed also move synchronously with the production platen; then, the first driving member drives the second bracket to extend relative to the first bracket in the first direction, and the second driving member drives the third bracket to extend relative to the second bracket in the first direction, and through two-stage extension, the material is sent to the working area of the operator; since the operator, the vehicle to be processed, and the conveying trolley all move synchronously with the production platen, the operator and the production trolley are basically in a relatively static state, thus facilitating the operator to directly take the material. The material can be a battery or other parts. Taking the material as a battery as an example, it saves the time and effort spent by the operator in taking and transporting the battery, and avoids the fatigue and waist injury of the operator caused by transporting the battery; since the production line is in a continuous running state during the process of the operator taking the battery and installing the battery on the vehicle to be processed, the production efficiency is effectively improved.

[0102] In one embodiment, the conveying trolley includes a starting position, the material sliding table further includes a material detection member, the number of the first roller lines is multiple, and the multiple first roller lines are arranged in sequence along a second direction, the second direction is perpendicular to the first direction, the number of the material detection members is the same as that of the first roller lines and they are arranged in one-to-one correspondence, and the material detection member is used to detect whether the material is placed on the first roller line; the material conveying system further includes a control module, and the control module is used to obtain the material information of the vehicle to be processed; please refer to Figure 11 , Figure 11 is a schematic flowchart of the second embodiment of the material conveying method provided by the present invention. The material detection member is electrically connected to the control module. The steps of S100 include:

[0103] S110, controlling the control module to obtain the material information of the vehicle to be processed;

[0104] S120, controlling each material detection member to judge whether the material matching the material information is placed on each first roller line;

[0105] S121, if the material matching the material information is placed on the first roller line, controlling the conveying trolley to move from the starting position to the first roller line where the material matching the material information is placed.

[0106] By arranging a plurality of first roller lines, more batteries can be accommodated, and batteries of the same specification or different specifications can be accommodated; the control module controls the material detection member according to the material information to detect whether the battery adapted to the vehicle to be processed is placed on the corresponding first roller line. If so, the material trolley moves to the nearest first roller line equipped with the battery to ensure that the taken and installed battery is adapted to the vehicle to be processed. It should be noted that if the material matching the material information is not placed on the first roller line, the steps of S120 are repeated.

[0107] In one embodiment, the material conveying system further includes a reset driving component, the reset driving component includes a driving part and a walking wheel, the driving part is arranged on the first bracket, the driving part is in transmission connection with the walking wheel, the walking wheel can be in contact with the ground, and the driving part can drive the walking wheel to rotate so that the conveying trolley moves along the second direction;

[0108] The step of controlling the conveying trolley to move from the starting position to the first roller line where the material matching the material information is placed includes:

[0109] Controlling the driving component to drive the walking wheel to rotate until the second roller line body moves to the first roller line body where the material matching the material information is placed;

[0110] The step of taking the material on the second roller line body and installing the material on the vehicle to be processed includes:

[0111] Controlling the first driving member to drive the second bracket to retract relative to the first bracket, and controlling the second driving member to drive the third bracket to retract relative to the second bracket;

[0112] Controlling the synchronization component to separate from the production platen;

[0113] The driving component is controlled to drive the traveling wheel to rotate until the conveying trolley moves to the starting position.

[0114] When it is necessary to go to the battery slide to pick up the battery matching the material information, the driving component drives the walking wheel to rotate, thereby moving the second roller line to the first roller line where the material is placed, eliminating the process of the operator moving on foot to the first roller line, saving manpower; when the operator completes taking the battery, the synchronous driving component drives the abutment component to separate from the production table, the first driving component drives the second bracket to reset, and the second driving component drives the third bracket to reset. In order to facilitate the subsequent removal of the battery and avoid occupying space and hindering the passage of other operators, it is necessary to move the entire conveying trolley to the position before the battery slide receives the battery, that is, move it to the starting position; this embodiment adds a reset drive component, and when it needs to move to the starting position, the driving component drives the walking wheel to rotate to move the conveying trolley to the starting position; when it is necessary to go to the battery slide to receive the battery, the driving component can also drive the walking wheel to rotate, so that the conveying trolley moves from the starting position to the battery slide to receive the battery.

[0115] In one embodiment, the material slide also includes a material blocking assembly, which includes a material blocking drive and a material blocking member drivingly connected to the material blocking drive, the material blocking drive is connected to the slide frame, and the material blocking member includes a blocking position and a releasing position, and the material blocking drive is used to drive the material blocking member to rise and fall so that the material blocking member can reciprocate between the blocking position and the releasing position; when the material blocking member is in the blocking position, the material blocking member can block the material from leaving the first roller line body from the material picking end; when the material blocking member is in the releasing position, the material can move from the material picking end to the feeding end; please refer to Figure 12 , Figure 12 The schematic flow chart of the third embodiment of the material conveying method provided by the present invention includes the following steps after step S100 and before step S200:

[0116] S101, control the material blocking driving member to drive the material blocking member to move from the blocking position to the releasing position.

[0117] The number of the first roller conveyors is multiple, and the multiple first roller conveyors are arranged in sequence along the second direction, and the second direction is perpendicular to the first direction. The number of the first roller conveyors is multiple, the number of the material detection members is the same as that of the first roller conveyors and they are arranged in one-to-one correspondence, and the material blocking assemblies are the same as the number of the first roller conveyors and are arranged in one-to-one correspondence; by arranging multiple first roller conveyors, more batteries can be accommodated, and batteries of the same specification or different specifications can be accommodated; the control module controls the material detection member to detect whether there is a battery adapted to the vehicle to be processed on the multiple first roller conveyors according to the material information. If so, the material trolley moves to the nearest first roller conveyor equipped with the battery, and then controls the corresponding material blocking driving member to drive the material blocking member to move from the blocking position to the releasing position, so that the battery can smoothly move from the material taking end to the feeding end. It should be noted that if the material leaves the first roller conveyor, control the material blocking driving member to drive the material blocking member to move from the releasing position to the blocking position.

[0118] In an embodiment, the first roller conveyor includes a first mounting frame and a first conveying roller rotatably mounted on the first mounting frame. The first mounting frame is connected to the sliding table frame. The first mounting frame is provided with the incoming material end and the material taking end opposite to each other along the first direction. The number of the first conveying rollers is multiple, and the multiple first conveying rollers are arranged at intervals in sequence along the first direction on the first mounting frame; at least one of the multiple first conveying rollers is an electric conveying roller, and the electric conveying roller can move the material from the material taking end to the feeding end; please refer to Figure 13 , Figure 13 It is a schematic flowchart of the fourth embodiment of the material conveying method provided by the present invention. The steps of S200 include:

[0119] S210, control the electric conveying roller to rotate until the material moves to the second roller conveyor.

[0120] When the conveying trolley moves to the material sliding table and is ready to take the material, the material blocking driving member drives the material blocking member to descend so that the material blocking member moves from the blocking position to the releasing position, so that the material taking end is communicated with the feeding end, and the electric conveying roller rotates, thereby driving the material to move from the material taking end to the feeding end relatively quickly, improving the material taking speed.

[0121] In an embodiment, the material conveying mechanism further includes a regional scanning assembly, the regional scanning assembly has a scanning area, and the material conveying method further includes the following steps:

[0122] S10, real-time control the regional scanning assembly to judge whether there is an operator in the scanning area;

[0123] S11. If there is an operator in the scanning area, control the conveying trolley to move at a reduced speed, and determine whether the distance between the operator and the area scanning component is less than a preset safety distance.

[0124] S12. If the distance between the operator and the area scanning component is less than the preset safety distance, control the conveying trolley to stop moving.

[0125] The material conveying system further includes an area scanning component, which includes a first area scanning piece, a second area scanning piece and a third area scanning piece. The first area scanning piece and the second area scanning piece are respectively arranged on both sides of the first bracket along the second direction, and the second direction is perpendicular to the first direction; the third area scanning piece is arranged on the third bracket, and the detection end of the third area scanning piece faces away from the first bracket. By setting the area scanning component to enhance safety, the first area scanning piece is used to detect whether an operator enters the scanning area during the process of the bracket component moving towards the battery sliding table. If an operator is detected to enter the scanning area during this process, the rotation speed of the walking driving part driving the walking wheels is reduced, thereby slowing down the overall moving speed of the conveying trolley. When the first area scanning piece detects that the distance between the operator and the first scanning piece is less than the preset safety distance, taking 200mm as an example for the preset safety distance, the movement of the conveying trolley is stopped to improve safety; similarly, the second area scanning piece is used to detect whether an operator enters the deceleration area during the process of the bracket component moving away from the battery sliding table. If so, the moving speed of the conveying trolley is slowed down. If the operator enters the scanning area within 200mm, the movement of the conveying trolley is stopped; similarly, during the process of the third bracket moving towards the working area, when the third area scanning piece detects that there is an operator in the scanning area, the extending speed of the first driving part and the second driving part is slowed down. When it is detected that the operator in the scanning area is relatively close to the third bracket, the movement of the third bracket is stopped to improve safety. It should be noted that if there is no operator in the scanning area, repeat the steps of S10; if the distance between the operator and the area scanning component is not less than the preset safety distance, repeat the steps of S10.
