Technical Field

[0001] This utility model relates to the field of automotive battery assembly technology, and in particular to a material conveying device. Background Technology

[0002] The existing battery assembly line is divided into a production area for placing production vehicles, a work area for operators to perform their work, and a battery slide for providing batteries. Currently, the operator's work process is as follows: after the production vehicle enters the production area, the operator walks from the work area to the battery slide, then takes the battery that matches the model of the production vehicle from the battery slide, and then walks back to the work area to install and tighten the battery. The whole process is time-consuming and labor-intensive. Utility Model Content

[0003] The main purpose of this invention is to propose a material conveying device that aims to solve the technical problem of time-consuming and labor-intensive battery installation.

[0004] To achieve the above objectives, the material conveying device proposed in this utility model includes:

[0005] A material slide table, comprising a slide table frame and a first roller conveyor, wherein the first roller conveyor is disposed on the slide table frame and has an infeed end and a take-up end disposed opposite to each other along a first direction, and the first roller conveyor is capable of moving material from the infeed end to the take-up end.

[0006] A conveying trolley includes a support assembly, a drive assembly, and a second roller conveyor. The support assembly includes a first support, a second support, and a third support, with the second support movably mounted on the first support and the third support movably mounted on the second support. The drive assembly includes a first drive member and a second drive member. The first drive member is disposed on the first support and is drively connected to the second support, enabling the first drive member to drive the second support to move relative to the first support along a first direction. The second drive member is disposed on the second support and is drively connected to the third support, enabling the second drive member to drive the third support to move relative to the second support along the first direction. The second roller conveyor is disposed on the first support and has an inlet end and an outlet end along the first direction. The first roller conveyor can move the material from the pick-up end to the inlet end. The inlet end is positioned higher than the outlet end, allowing the material to move from the inlet end to the outlet end under gravity.

[0007] In one 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 slide frame. The first mounting frame has the material receiving end and the material taking end arranged 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 along the first direction on the first mounting frame.

[0008] The plurality of first conveying rollers includes at least one electrically driven conveying roller, which is capable of moving the material from the picking end to the feeding end;

[0009] And / or, the height of the receiving end is higher than the height of the taking end, so that the material can move from the taking end to the feeding end under the action of gravity.

[0010] In one embodiment, the material slide further includes a material blocking assembly, which includes a material blocking drive and a material blocking member pulsatorically 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 release position. The material blocking drive is used to drive the material blocking member to move up and down, so that the material blocking member can reciprocate between the blocking position and the release position. When the material blocking member is in the blocking position, the material blocking member can prevent the material from leaving the first mounting frame from the picking end. When the material blocking member is in the release position, the material can move from the picking end to the feeding end.

[0011] In one embodiment, the first roller conveyor further includes a first roller strip and a second roller strip. Both the first roller strip and the second roller strip are connected to the first mounting frame. The first roller strip and the second roller strip are respectively arranged on both sides of the first conveying roller along the axial direction of the first conveying roller. The first roller strip, the second roller strip, and the plurality of first conveying rollers form a transport channel for the material to flow.

[0012] In one embodiment, the material slide further includes a material detection element disposed on the slide frame, the material detection element being used to detect whether the material is placed on the first roller conveyor.

[0013] In one embodiment, there are multiple first roller bodies, which are arranged sequentially along a second direction, which is perpendicular to the first direction.

[0014] In one embodiment, the conveying trolley further includes a roller assembly, the roller assembly including load-bearing wheels disposed at the bottom of the first support; the material conveying device further includes a synchronization component, the synchronization component including a synchronization drive and an abutment component pulsatingly connected to the synchronization drive, the synchronization drive is disposed on the first support, the synchronization drive can drive the abutment component to abut against the production table, so that the production table can drive the conveying trolley to move synchronously along a second direction through the synchronization component, the second direction being perpendicular to the first direction.

[0015] In one embodiment, the material conveying device further includes a reset drive assembly, which includes a drive component and a traveling wheel. The drive component is disposed on the first bracket and is throttle-connected to the traveling wheel. The traveling wheel is capable of contacting the ground, and the drive component is capable of driving the traveling wheel to rotate so that the conveying trolley moves along the second direction.

[0016] In one embodiment, the material slide further includes a trolley detection component, the conveying trolley includes a material picking position, the driving component can drive the traveling wheels to rotate so that the conveying trolley moves to or away from the material picking position; the conveying trolley is at the material picking position, the receiving end can be connected to the feeding end, and the detection component is used to detect whether the conveying trolley is located at the material picking position.

[0017] In one embodiment, the roller assembly further includes a guide wheel disposed at the bottom of the first bracket, the guide wheel being configured to roll in cooperation with a track extending in a second direction.

[0018] The technical solution of this utility model is illustrated using batteries as an example. Batteries are received from the first roller conveyor via the second roller conveyor. The batteries move from the picking end of the first roller conveyor to the feeding end of the second roller conveyor. Since the feeding end of the mounting frame is higher than the discharging end, the batteries located at the feeding end will automatically move to the discharging end under the action of gravity. The first driving component drives the second support to move away from the first support along the first direction, and the second driving component drives the third support to move away from the second support along the first direction, thereby achieving two-stage extension. This transports the batteries located on the second roller conveyor to the working area, saving the time and effort spent by the operator in picking up and moving the batteries.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0034] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] The existing battery assembly line is divided into a production area for placing production vehicles, a work area for operators to perform their work, and a battery slide for providing batteries. Currently, the operator's work process is as follows: after the production vehicle enters the production area, the operator walks from the work area to the battery slide, then takes the battery that matches the model of the production vehicle from the battery slide, and then walks back to the work area to install and tighten the battery. The whole process is time-consuming and labor-intensive.

[0037] The inventors discovered that the distance an operator walks from the work area to the battery slide and back is approximately 6 meters. Based on a daily production of about 400 vehicles, this translates to an average monthly walking distance of about 50.4 kilometers, which is extremely labor-intensive. Furthermore, the entire process takes about 10 seconds, again assuming a daily production of 400 vehicles, meaning an operator would need to spend approximately 23.3 hours per month on this process. Additionally, each battery weighs approximately 10.9 kilograms, and handling batteries for extended periods can easily lead to physical fatigue and lower back injuries, negatively impacting physical and mental health.

[0038] This invention proposes a material conveying device, which aims to solve the technical problem of time-consuming and labor-intensive battery installation.

[0039] Please see Figure 1 , Figure 2 and Figure 5In one embodiment of this utility model, the material conveying device 100 includes a material slide 1 and a conveying trolley 2. The material slide 1 includes a slide frame 11 and a first roller conveyor 12. The first roller conveyor 12 is disposed on the slide frame 11. The first roller conveyor 12 has an infeed end 1211 and a take-up end 1212 arranged opposite to each other along a first direction. The first roller conveyor 12 can move the material from the infeed end 1211 to the take-up end 1212. The conveying trolley 2 includes a support assembly 21, a drive assembly 22, and a second roller conveyor 23. The support assembly 21 includes a first support 211, a second support 212, and a third support 213. The second support 212 is movably mounted on the first support 211. The third support 213 is movably mounted on the second support 212. The drive assembly 22 includes a first drive member 221 and a second drive member 222. The first drive member 221... The first drive member 221 is driven by the first support 211 and the second support 212, so that the first drive member 221 can drive the second support 212 to move relative to the first support 211 in a first direction; the second drive member 222 is driven by the second support 212 and the third support 213, so that the second drive member 222 can drive the third support 213 to move relative to the second support 212 in a first direction; the second roller conveyor 23 is set on the first support 211 and the second roller conveyor 23 is respectively provided with a feeding end 2311 and a discharging end 2312 along the first direction. The first roller conveyor 12 can move the material from the feeding end 1212 to the feeding end 2311. The feeding end 2311 is set 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.

[0040] The technical solution of this utility model involves moving the conveyor trolley 2 to the material slide table 1 so that the picking end 1212 of the first roller conveyor 12 is directly opposite the feeding end 2311 of the second roller conveyor 23. The material on the first roller conveyor 12 is moved from the picking end 1212 to the feeding end 2311 through the first roller conveyor 12. Since the height of the feeding end 2311 is higher than the height of the discharging end 2312, the material can move from the feeding end 2311 to the discharging end 2312 under the action of gravity, thereby realizing automatic material picking. 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 the two-stage extension, the material is delivered to the operator's work area, making it convenient for the operator to pick up directly. This saves the time and effort spent by the operator to pick up and carry the battery 200, and avoids fatigue and back injury caused by the operator carrying the battery 200. It should be noted that the first driving component 221 and the second driving component 222 can be either pneumatic cylinders or hydraulic cylinders; there is no limitation on this. When both the first driving component 221 and the second driving component 222 are pneumatic cylinders, the stroke of the first driving component 221 can be 600mm, and the stroke of the second driving component 222 can be 680mm. Through the first driving component 221 and the second driving component 222, the third support 213 can achieve a total telescopic movement distance of 1250mm, enabling cross-line operations. The first support 211 and the second support 212 can move relative to each other through a sliding engagement of a slide groove and a slide rail, or through a guide shaft and a linear bearing; again, there is no limitation on this. Similarly, the second support 212 and the third support 213 can move relative to each other through a sliding engagement of a slide groove and a slide rail or a guide shaft and a linear bearing. The material can be a battery 200 or other components. It should also be noted that the first direction is Figure 1 The front and back directions are shown, and the second direction is... Figure 1 The left and right directions are shown.

[0041] Please see Figure 1 and Figure 3In one 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 frame 11. The first mounting frame 121 has a material receiving end 1211 and a material taking end 1212 arranged opposite to each other along a first direction. There are multiple first conveying rollers 122, which are arranged sequentially and spaced apart along the first direction on the first mounting frame 121. Among the multiple first conveying rollers 122, there is at least one electric conveying roller. The electric conveying roller can move the material from the taking end 1212 to the feeding end 2311. By setting the electric conveying roller, the material located on the first roller conveyor 12 is provided with conveying power. The electric conveying roller can move the material from the material receiving end 1211 to the taking end 1212 and from the taking end 1212 to the feeding end 2311, realizing the automatic material taking of the conveying trolley 2, eliminating the manual material taking step and saving manpower.

[0042] In one embodiment, the height of the receiving end 1211 is higher than the height of the picking end 1212, so that the material can move from the picking end 1212 to the feeding end 2311 under the action of gravity. By setting the height of the receiving end 1211 to be greater than the height of the picking end 1212, the material located on the first roller conveyor 12 can automatically move from the receiving end 1211 to the picking end 1212 under the action of gravity, and can also move from the picking end 1212 to the feeding end 2311 under the action of gravity, realizing automatic material picking by the conveyor trolley 2, eliminating the manual material picking step, and saving manpower.

[0043] Please see Figure 3In one embodiment, the material slide 1 further includes a material blocking assembly 13, which includes a material blocking drive 131 and a material blocking member 132 pulsatorically connected to the material blocking drive 131. The material blocking drive 131 is connected to the slide frame 11. The material blocking member 132 includes a blocking position and a release position. The material blocking drive 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 release position. When the material blocking member 132 is in the blocking position, the material blocking member 132 can prevent the material from leaving the first mounting frame 121 from the picking end 1212. When the material blocking member 132 is in the release position, the material can move from the picking end 1212 to the feeding end 2311. By setting the material blocking component 13, when the material moves to the picking end 1212, if the conveyor trolley 2 has not yet moved to the material slide 1, the material blocking drive component 131 can drive the material blocking component 132 to rise, so that the material blocking component 132 moves to the blocking position. The material blocking component 132 in the blocking position will abut against the material at the picking end 1212, thereby restricting the material from leaving the picking end 1212 and preventing the material from falling and being damaged. When the conveyor trolley 2 moves to the material slide 1, ready to pick up the material, the material blocking drive component 131 drives the material blocking component 132 to fall, so that the material blocking component 132 moves from the blocking position to the release position, so that the picking end 1212 is connected to the feeding end 2311. The electric conveying roller rotates, thereby driving the material to move from the picking end 1212 to the feeding end 2311 more quickly, increasing the picking speed. It should be noted that the material blocking drive component 131 can be a pneumatic cylinder or a hydraulic cylinder, which is not limited here. The material stop 132 can be a material stop plate or a material stop block.

[0044] Please see Figure 2 and Figure 3 In one embodiment, the first roller conveyor 12 further includes a first roller strip 123 and a second roller strip 124. Both the first roller strip 123 and the second roller strip 124 are connected to the first mounting frame 121. The first roller strip 123 and the second roller strip 124 are respectively arranged on both sides of the first conveying roller 122 along its axial direction. The first roller strip 123, the second roller strip 124, and the multiple first conveying rollers 122 form a transport channel for material flow. By setting the first roller strip 123 and the second roller strip 124, the material can move more smoothly on the first roller conveyor 12. That is, when the material contacts the first or second gear rack, due to rolling friction, the friction force is smaller than sliding friction, thus allowing the material to move more smoothly on the first roller conveyor 12. Furthermore, the setting of the first roller strip 123 and the second roller strip 124 restricts the material on the first roller conveyor 12 from falling off the edge of the conveyor, improving the reliability of transportation.

[0045] Please see Figure 3In one embodiment, the material slide 1 further includes a material detection element 14, which is disposed on the slide frame 11. The material detection element 14 is used to detect whether there is material placed on the first roller conveyor 12. By setting the material detection element 14 to detect whether there is a battery 200 on the first roller conveyor 12, the conveyor trolley 2 will move towards the material slide 1 if there is a battery 200. In addition, the material detection element 14 can also detect whether the battery 200 located on the first roller conveyor 12 matches the model of the vehicle to be processed, avoiding the installation of batteries 200 that do not match the production information onto the vehicle to be processed, ensuring the quality of the vehicle and reducing the number of rework. The material detection element 14 can be a photoelectric switch or a contact switch.

[0046] Please see Figures 1 to 3 In one embodiment, there are multiple first roller conveyor lines 12, which are arranged sequentially along a second direction perpendicular to the first direction. The number of first roller conveyor lines 12 is the same as the number of first roller conveyor lines 12 and they are arranged in a one-to-one correspondence. The number of material detection components 14 is the same as the number of first roller conveyor lines 12 and they are arranged in a one-to-one correspondence. By setting multiple first roller conveyor lines 12, more batteries 200 can be accommodated, including batteries of the same specification and batteries of different specifications. The control module, based on production information, controls the material detection components 14 to detect whether a battery 200 compatible with the vehicle to be processed is placed on the multiple first roller conveyor lines 12. If so, the material trolley moves to the nearest first roller conveyor line containing the battery 200, and then controls the corresponding blocking drive component 131 to drive the blocking component 132 from the blocking position to the release position, so that the battery 200 can smoothly move from the picking end 1212 to the feeding end 2311.

[0047] Please see Figure 4 According to one embodiment of the present invention, the second roller conveyor 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 a third support 213. The second mounting frame 231 has an infeed end 2311 and an outlet end 2312 arranged opposite to each other along a first direction. Multiple second conveying rollers 232 are arranged sequentially and spaced apart along the first direction on the second mounting frame 231. The second roller conveyor 23 also includes two conveying roller strips 233, which are respectively arranged on both sides of the second conveying roller 232 along a 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 infeed end 2311 to the outlet end 2312. It should be noted that the second conveying rollers 232 are all unpowered rollers.

[0048] Please see Figure 5 , Figure 6 and Figure 8 In one embodiment, the conveying trolley 2 further includes a roller assembly, which includes a load-bearing wheel 241 disposed at the bottom of the first support 211; the material conveying device 100 further includes a synchronization component 3, which includes a synchronization drive 31 and an abutment 32 that is pulsatorically connected to the synchronization drive 31. The synchronization drive 31 is disposed on the first support 211 and can drive the abutment 32 to abut against the production table, so that the production table can drive the conveying trolley 2 to move synchronously in a second direction through the synchronization component 3. The second direction is perpendicular to the first direction. When the vehicle enters the synchronization position, the synchronization drive 31 drives the abutment 32 to move downwards, so that the abutment 32 is pressed against the production platform. Because the bottom of the first support 211 is equipped with a load-bearing wheel 241, this load-bearing wheel 241 not only provides reliable support for the first support 211, but also allows the production platform to more easily move synchronously with the first support 211, the second support 212, and the third support 213 via the abutment 32 while the abutment 32 is pressed against the production platform. At this time, the operator, the vehicle to be processed, and the battery 200, which is also located on the third support 213, are in a basically relatively stationary state, making it easy for the operator to remove the battery 200 from the third support 213 and then install the battery 200 onto the vehicle to be processed. The production line moves continuously during this process, ensuring production efficiency. It should be noted that the synchronization drive 31 can be a cylinder or a hydraulic cylinder; there is no limitation here. The abutment 32 can be an abutment plate or an abutment block.

[0049] Please see Figure 8 According to one embodiment of the present invention, the synchronization component 3 further includes a synchronization overload detection component 33, which is used to detect whether an overload occurs during the synchronous movement of the support component 21 and the production table. If so, synchronization is stopped to reduce the probability of equipment damage or production line accidents.

[0050] Please see Figure 9In one embodiment, the material conveying device 100 further includes a reset drive assembly 4, which includes a drive component 41 and a traveling wheel 42. The drive component 41 is disposed on the first bracket 211 and is connected to the traveling wheel 42 in a transmission manner. The traveling wheel 42 can abut against the ground, and the drive component 41 can drive the traveling wheel 42 to rotate so that the conveying trolley 2 moves in the second direction. After the operator finishes retrieving the battery 200, the synchronous drive component 31 drives the abutment component 32 to separate from the production table. The first drive component 221 drives the second bracket 212 to reset, and the second drive component 222 drives the third bracket 213 to reset. In order to facilitate the subsequent retrieval of the battery 200 and avoid occupying space and obstructing the passage of other operators, the entire conveyor trolley 2 needs to be moved to the position before the battery 200 receiving slide, that is, moved to the starting position. In this embodiment, by adding a reset drive component 4, when it is necessary to move to the starting position, the drive component 41 drives the traveling wheel 42 to rotate, so that the conveyor trolley 2 moves to the starting position. When it is necessary to receive the battery 200 at the battery 200 slide, the drive component 41 can also drive the traveling wheel 42 to rotate, so that the conveyor trolley 2 moves from the starting position to the battery 200 slide to receive the battery 200.

[0051] Please see Figure 9 According to one embodiment of the present invention, the driving component 41 includes a lifting driving component 411 and a walking driving component 412. The lifting driving component 411 is disposed on the first bracket 211, and the output end of the lifting driving component 411 is connected to the walking driving component 412. The walking driving component 412 is connected to the walking wheel 42 in a transmission manner, and the walking driving component 412 can drive the walking wheel 42 to rotate. The lifting driving component 411 is used to drive the walking wheel 42 to rise and fall through the walking driving component 412, so that the walking wheel 42 abuts or separates from the ground. When the walking wheel 42 abuts the ground, the walking driving component 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 slide receiving battery 200 or to the battery 200 slide receiving battery 200, the lifting driving component 411 drives the walking driving component 412 and the walking wheel 42 to fall together until the walking wheel 42 contacts the ground, and then the walking driving component 412 drives the walking wheel 42 to rotate, so that the entire material conveying mechanism moves. When the support assembly 21 moves synchronously with the production table, the lifting drive component 411 drives the traveling wheel 42 to rise and separate from the ground, preventing the traveling wheel 42 from contacting the ground and affecting the synchronous operation of the support assembly 21 and the production table. It should be noted that the lifting drive component 411 can be a cylinder or a hydraulic cylinder, which is not limited here. The traveling drive component 412 can be a servo motor or a stepper motor, which is not limited here. Taking a motor as an example, the motor can drive the traveling wheel 42 to rotate through gear transmission, or it can drive the gear to rotate through direct drive.

[0052] According to one embodiment of this utility model, the lifting drive component 411 is a cylinder, and the cylinder's extension shaft is connected to the fixed frame. The walking drive component 412 is a motor, which is mounted on the fixed frame. The motor can drive the walking wheel 42 to rotate via gear transmission or directly. The fixed frame and the first support 211 achieve sliding cooperation through a slider and a slide rail, improving the stability of the walking wheel 42's lifting and lowering. In addition, the fixed frame is equipped with a descent detection switch 43, which is used to detect whether the fixed frame has descended to the designated position. If so, it indicates that the walking wheel 42 has made contact with the ground. This signal is used to determine whether the walking wheel 42 has descended to the designated position and made contact with the ground.

[0053] Please see Figure 2 and Figure 3 In one embodiment, the material slide 1 further includes a trolley detection component 15. The conveying trolley 2 includes a material picking position. The driving component 41 can drive the traveling wheels 42 to rotate so that the conveying trolley 2 moves to or away from the material picking position. When the conveying trolley 2 is in the material picking position, the receiving end 1211 can be connected to the feeding end 2311. The detection component is used to detect whether the conveying trolley 2 is located in the material picking position. The number of trolley detection units 15 and the number of first roller conveyor bodies 12 are the same and they are set one-to-one. According to the production information, the control module controls the material detection unit 14 to detect whether there is a battery 200 that is compatible with the vehicle to be processed on multiple first roller conveyor bodies 12. If there is, the drive unit 41 drives the walking wheel 42 to rotate until the trolley detection unit 15 detects that the material trolley has moved to the first roller conveyor body 12 where the battery 200 is placed. Then, the corresponding material blocking drive unit 131 controls the material blocking unit 132 to move from the blocking position to the release position so that the battery 200 can move smoothly from the material picking end 1212 to the feeding end 2311. This realizes that the conveying trolley 2 can automatically receive the battery 200 that is compatible with the vehicle to be processed according to the production information.

[0054] Please see Figure 5 and Figure 7 In one embodiment, the roller assembly further includes a guide wheel 242, which is disposed at the bottom of the first support 211 and is used to roll in engagement with a track extending in a second direction. By setting the guide wheel 242 to roll in engagement with the track, the movement direction of the first support 211 is guided, ensuring that the first support 211 can reciprocate along the second direction.

[0055] Please see Figure 4 and Figure 6In one embodiment, the conveyor trolley 2 further includes a carrying platform 25, which is disposed on the third support 213. The discharge end 2312 is positioned facing the carrying platform 25 so that materials leaving the discharge end 2312 can move to the carrying platform 25. By setting up the carrying platform 25 to carry materials, taking a battery 200 as an example, after the battery 200 leaves the discharge end 2312, it will move to the carrying platform 25, where the carrying platform 25 carries the battery 200 for the operator to pick up.

[0056] Please see Figure 4 In one embodiment, the platform 25 includes a platform body 251 and a baffle 252. The platform body 251 is mounted on the third support 213. The discharge end 2312 is positioned at one end of the platform 25, and the other end of the platform 25 is provided with a baffle 252. The baffle 252 is used to abut against the material so that the baffle 252 can restrict the material moving in the first direction from leaving the platform body 251. Since the feed end 2311 is higher than the discharge end 2312, the battery 200 leaving the discharge end 2312 has a certain initial velocity. In order to prevent the battery 200 from sliding off the platform body 251, the baffle 252 is provided on the platform body 251. The baffle 252 abuts against the battery 200 to restrict the battery 200 from continuing to move in the first direction, so that the battery 200 can be smoothly stopped on the platform body 251 for the operator to pick up.

[0057] Please see Figure 4 and Figure 6 According to one embodiment of the present invention, in one implementation, the conveying trolley 2 further includes a battery detection component 26. The battery detection component 26 is disposed on the third bracket 213, with its detection end facing the platform 25. The detection component is used to detect whether material is placed on the platform 25. By setting the battery detection component 26 to detect whether a battery 200 is placed on the platform 25, it is used to determine whether the battery 200 on the battery 200 slide has successfully moved to the platform 25 via the conveying slide. The battery detection component 26 can be a through-beam switch or a contact switch, and there is no limitation herein.

[0058] Please see Figure 5 and Figure 6 According to one embodiment of the present invention, a three-color light 27 is provided on the bracket assembly 21. By providing the three-color light 27, the operator can promptly grasp the equipment status information of the conveying trolley 2 based on the color of the three-color light 27.

[0059] Please see Figure 4 According to another embodiment of the present invention, the third bracket 213 is also provided with a work completion button 28. When the operator finishes taking the battery 200, he presses the work completion button 28, and the first driving member 221 and the second driving member 222 respectively drive the second bracket 212 and the third bracket 213 to reset.

[0060] Please see Figure 6 and Figure 7 In one embodiment, the material conveying device 100 further includes a region scanning component 5, which includes a first region scanning element 51, a second region scanning element 52, and a third region scanning element 53. The first and second region scanning elements 51 and 52 are respectively disposed on both sides of the first support 211 along a second direction, which is perpendicular to the first direction. The third region scanning element 53 is disposed on the third support 213, with its detection end facing away from the first support 211. The region scanning component 5 enhances safety. The first region scanning element 51 detects whether an operator enters the detection area during the movement of the support assembly 21 towards the slide of the battery 200. If an operator is detected entering the detection area, the rotation speed of the driving wheel 42 driven by the walking drive 412 is reduced, thereby slowing down the overall movement speed of the conveying trolley 2. When the first region scanning element 51 detects that the distance between the operator and the first scanning element is less than a preset safety distance (e.g., 200mm), the movement of the conveying trolley 2 is stopped, improving safety. Similarly, the second region scanning element 52 is used to detect whether an operator enters the detection area along a second direction, which is perpendicular to the first direction. The detection end of the third region scanning element 53 faces away from the first support 211. During the movement of the detection bracket assembly 21 away from the slide of the battery 200, if a worker enters the deceleration zone, the movement speed of the conveyor trolley 2 is reduced. If a worker enters the 200mm detection area, the movement of the conveyor trolley 2 is stopped. Similarly, during the movement of the third bracket 21313 towards the work area, when the third area scanner 53 detects a worker in the detection area, the extension speed of the first drive member 221 and the second drive member 222 is reduced. When the worker in the detection area is detected to be close to the third bracket 213, the movement of the third bracket 213 is stopped to improve safety.

[0061] According to one embodiment of the present invention, a collision protection bar 7 is provided on the side of the first bracket 211 facing the slide of the battery 200 to protect the first bracket 211.

[0062] Please see Figure 4 and Figure 6 In one embodiment, the material conveying device 100 further includes a contact assembly 6, which includes a first safety contact 61, a second safety contact 62, and a third safety contact 63. The first safety contact 61 and the second safety contact 62 are respectively disposed on both sides of the third support 213 along a second direction, and the third safety contact 63 is disposed on the side of the third support 213 away from the feed end 2311 along a first direction. By setting the first safety contact 61, the second safety contact 62, and the third safety contact 63, collision checks are performed. When an object collides with any one of the first safety contact 61, the second safety contact 62, and the third safety contact 63, the conveying trolley 2 stops moving, thereby improving safety.
