[0047] Embodiment

[0048] Please refer to Figure 1 and Figure 2 simultaneously. This embodiment provides a lift 10, specifically a lift 10 with a rotatable pitch adjustment function. The lift 10 has a first direction X, and the lift 10 includes a frame 100, a lifting mechanism 200, a pitch adjustment mechanism 300, and a rotating mechanism 400.

[0049] Among them, the lifting mechanism 200 includes a lifting seat 210, and the lifting seat 210 is disposed on the frame 100 in a liftable manner.

[0050] Please combine Figure 3 simultaneously. The pitch adjustment mechanism 300 includes a pitch adjustment driving member 310 and at least two support seats 320. The pitch adjustment driving member 310 is connected to the lifting seat 210, and the pitch adjustment driving member 310 is connected to each of the at least two support seats 320. The support seats 320 are slidably connected to the lifting seat 210, and the support seats 320 carry a tooling plate 30. In addition, the pitch adjustment driving member 310 drives the at least two support seats 320 to slide in the first direction X towards each other or away from each other.

[0051] Please combine Figure 4, the rotating mechanism 400 includes a lifting driving member 410, a lifting seat 420, a positioning seat 430, and a rotating driving member 440. The lifting driving member 410 is connected to the lifting seat 210. The lifting driving member 410 is connected to the lifting seat 420 and drives the lifting seat 420 to move up and down. The positioning seat 430 is rotatably arranged on the lifting seat 420 and is located between at least two support seats 320 along the first direction X. The positioning seat 430 positions the tooling plate 30 when the lifting seat 420 rises. The rotating driving member 440 is connected to the lifting seat 420. The rotating driving member 440 is connected to the positioning seat 430 and drives the positioning seat 430 to rotate.

[0052] When using the above-mentioned elevator 10, the tooling plate 30 after the previous process is transferred from one layer of the conveyor line 20 to the support seat 320 of the elevator 10, and the tooling plate 30 is carried by the support seat 320. The lifting driving member 410 drives the lifting seat 420 to rise, thereby driving the positioning seat 430 to rise. The positioning seat 430 carries the tooling plate 30 and at the same time disengages the tooling plate 30 from the support seat 320. Subsequently, the rotating driving member 440 drives the positioning seat 430 to rotate, driving the tooling plate 30 to rotate by a certain angle. At the same time, the variable pitch driving member 310 drives at least two support seats 320 to slide along the first direction X towards or away from each other, so that the distance between at least two support seats 320 is adapted to the dimension of the rotated tooling plate 30 along the first direction X. Therefore, different models of tooling plates 30 can be adapted. On this basis, the lifting driving member 410 drives the lifting seat 420 to descend, thereby driving the positioning seat 430 to descend, so that the tooling plate 30 is carried by the support seats 320 after the pitch is changed again. Finally, the lifting seat 210 drives the variable pitch mechanism 300, the rotating mechanism 400, and the tooling plate 30 to move up and down as a whole, so as to transfer the tooling plate 30 to another layer of the conveyor line 20 and then convey it to the next process. During this process, under the action of the rotating mechanism 400, the orientation of the tooling plate 30 can be changed, so that while realizing the return of the tooling plate 30, it can adapt to the working conditions where the orientations of the tooling plate 30 in the previous and next processes are different.

[0053] Please refer to Figure 5 , Figure 6 and Figure 7 , in some embodiments, the lifting mechanism 200 further includes a lifting driving member 220. The lifting driving member 220 is connected to the frame 100. The lifting driving member 220 is connected to the lifting seat 210 and drives the lifting seat 210 to move up and down, thereby driving the variable pitch mechanism 300, the rotating mechanism 400, and the tooling plate 30 to move up and down as a whole.

[0054] In this embodiment, the lifting driving member 220 is composed of a first mounting seat 221, a rotating shaft 222, a roller 223, a lifting motor 224, and a lifting track 225.

[0055] Among them, the first mounting seat 221 is fixedly connected to the bottom surface of the lifting seat 210. The axis of the rotating shaft 222 is horizontal, and the rotating shaft 222 is rotatably arranged on the first mounting seat 221. The roller 223 is sleeved on one end of the rotating shaft 222 and is key-connected to the rotating shaft 222. The lifting motor 224 is fixedly connected to the first mounting seat 221, and the shaft of the lifting motor 224 is connected to the other end of the rotating shaft 222. In addition, the lifting track 225 extends in the vertical direction, the lifting track 225 is fixedly connected to the frame 100, and the lifting track 225 cooperates with the outer periphery of the roller 223.

[0056] During use, the lifting motor 224 drives the rotating shaft 222 to rotate, thereby driving the roller 223 to rotate, so that the roller 223 rolls upward or downward along the lifting track 225, and finally drives the lifting seat 210 to rise or fall through the rotating shaft 222 and the first mounting seat 221.

[0057] Exemplarily, the lifting track 225 is provided with sawteeth, and the roller 223 is a gear. At this time, the cooperation between the lifting track 225 and the outer periphery of the roller 223 specifically means that the sawteeth on the lifting track 225 mesh with the outer periphery of the roller 223.

[0058] Optionally, the lifting driving members 220 are arranged in pairs on two opposite sides of the lifting seat 210 and are respectively located in the middle of the two sides of the lifting seat 210, so that the lifting seat 210 is uniformly stressed and lifted and lowered smoothly.

[0059] In another embodiment of the present application, the lifting driving member 220 may also be an electric cylinder or an oil cylinder, etc., and the present embodiment does not limit this.

[0060] Furthermore, the lifting mechanism 200 further includes a second detection member 230. The second detection member 230 is connected to the frame 100, and the second detection member 230 is electrically connected to the lifting driving member 220.

[0061] Correspondingly, the frame 100 has a feeding position 110 and a discharging position 120. When the second detection member 230 detects that the lifting seat 210 reaches the feeding position 110 or the discharging position 120, it outputs a signal to the lifting driving member 220 so that the lifting driving member 220 stops driving the lifting seat 210.

[0062] For example, when the lifting seat 210 reaches the feeding position 110, the second detection member 230 detects the lifting seat 210 and outputs a signal to the lifting driving member 220, so that the lifting driving member 220 stops driving the lifting seat 210, and further the lifting seat 210 stays at the feeding position 110. On this basis, the second detection member 230 also outputs a signal to other control modules to prompt that feeding can be performed and allow the tooling plate 30 to enter the elevator 10.

[0063] Similarly, when the lifting seat 210 reaches the discharging position 120, the second detector 230 detects the lifting seat 210 and outputs a signal to the lifting drive 220, causing the lifting drive 220 to stop driving the lifting seat 210, and thus the lifting seat 210 stays at the discharging position 120. On this basis, the second detector 230 also outputs a signal to other control modules to indicate that discharging is possible and allows the tooling plate 30 to leave the elevator 10.

[0064] In contrast, the traditional elevator 10 does not have in-position detection for lifting. When the elevator 10 is not at the feeding position 110, the tooling plate 30 still flows into the elevator 10. When the elevator 10 is not at the discharging position 120, the tooling plate 30 still leaves the elevator 10. Both will cause the tooling plate 30 to fall, damage the equipment, and have poor safety.

[0065] Furthermore, the lifting mechanism 200 further includes a hovering positioning member 240. The hovering positioning member 240 is connected to the lifting seat 210, the hovering positioning member 240 is electrically connected to the second detector 230, and the hovering positioning member 240 is inserted into the frame 100 when the second detector 230 detects that the lifting seat 210 reaches the feeding position 110 or the discharging position 120 to position the lifting seat 210.

[0066] Specifically, the hovering positioning member 240 is composed of a second mounting seat 241, a positioning pin 242, and a positioning cylinder 243.

[0067] Among them, the second mounting seat 241 is fixedly connected to the top surface of the lifting seat 210. The positioning pin 242 is slidably inserted through the second mounting seat 241 in the horizontal direction. The cylinder block of the positioning cylinder 243 is fixedly connected to the second mounting seat 241, and the piston rod of the positioning cylinder 243 is connected to the positioning pin 242.

[0068] Correspondingly, a positioning member 130 is provided on the frame 100. The positioning member 130 extends in the vertical direction, the positioning member 130 is fixedly connected to the frame 100, a plurality of positioning holes 131 are formed on the side surface of the positioning member 130, and each positioning hole 131 is arranged in the numerical direction.

[0069] When the second detector 230 detects that the lifting seat 210 reaches the feeding position 110 or the discharging position 120, the piston rod of the positioning cylinder 243 extends, driving the positioning pin 242 to insert into the positioning hole 131 on the positioning member 130. At this time, the second mounting seat 241 is pin-connected and fixed to the positioning member 130 through the positioning pin 242, so that the lifting seat 210 hovers at the feeding position 110 or the discharging position 120.

[0070] After the tooling plate 30 enters the elevator 10 or after the tooling plate 30 leaves the elevator 10, the piston rod of the positioning cylinder 243 retracts, driving the positioning pin 242 to disengage from the positioning hole 131, and releasing the connection between the second mounting seat 241 and the positioning member 130. At this time, the lifting drive member 220 can drive the lifting seat 210 to lift again.

[0071] Furthermore, the lifting mechanism 200 further includes a guide wheel 250, and the guide wheel 250 is rotatably arranged on the lifting seat 210 through a third mounting seat 251.

[0072] Correspondingly, a guide rail 140 is provided on the frame 100. The guide rail 140 extends in the vertical direction, the guide rail 140 is fixedly connected to the frame 100, and the guide wheels 250 are arranged in pairs on both sides of the guide rail 140 and respectively abut against the side surfaces of the guide rail 140.

[0073] During the lifting process of the lifting seat 210, the guide wheel 250 cooperates with the guide rail 140, which can limit and guide the lifting seat 210, ensure that the lifting seat 210 runs vertically during lifting, prevent the lifting seat 210 from skewing, and ensure smooth lifting.

[0074] Furthermore, four groups of first slide rails 150 and first sliders 160 are also provided on the frame 100. The first slide rails 150 extend in the vertical direction, and the first slide rails 150 are fixedly connected to the frame 100. The first sliders 160 correspond to the first slide rails 150 one by one and are slidably connected to the corresponding first slide rails 150. At the same time, the four first sliders 160 are respectively located at the four top corners of the lifting seat 210 and are fixedly connected to the lifting seat 210.

[0075] During the lifting process of the lifting seat 210, the first slide rail 150 cooperates with the first slider 160, which can also limit and guide the lifting seat 210, ensure that the lifting seat 210 runs vertically during lifting, prevent the lifting seat 210 from skewing, and ensure smooth lifting.

[0076] Please refer to again Figure 3 , in this embodiment, the variable pitch mechanism 300 includes a variable pitch drive member 310 and two support seats 320, and the two support seats 320 are arranged opposite to each other along the first direction X.

[0077] During use, the variable pitch drive member 310 drives one of the support seats 320 to move forward along the first direction X, and drives the other support seat 320 to move backward along the first direction X, so that the two support seats 320 approach or move away from each other.

[0078] Exemplarily, the pitch-changing driving member 310 is a pitch-changing cylinder, and the number of pitch-changing driving members 310 is two, corresponding to the two supporting seats 320 one by one. The cylinder block of the pitch-changing cylinder is fixedly connected to the lifting seat 210, the piston rod of the pitch-changing cylinder extends and retracts along the first direction X, and the piston rods of the pitch-changing cylinders are respectively connected to the corresponding supporting seats 320.

[0079] During use, the piston rods of the two pitch-changing cylinders extend simultaneously, thereby driving the two supporting seats 320 to move away from each other. The piston rods of the two pitch-changing cylinders retract simultaneously, thereby driving the two supporting seats 320 to move closer to each other.

[0080] Alternatively, the pitch-changing driving member 310 can also be composed of a lead screw, a driving motor, and two nut seats. The lead screw extends along the first direction X and is rotatably connected to the lifting seat 210. A left-handed thread is provided at one end of the lead screw, and a right-handed thread is provided at the other end. The shaft of the driving motor is connected to one end of the lead screw to drive the lead screw to rotate. The two nut seats are respectively sleeved on the lead screw. One nut seat is engaged with the left-handed thread on the lead screw and is connected to one of the supporting seats 320, and the other nut seat is engaged with the right-handed thread on the lead screw and is connected to the other supporting seat 320.

[0081] During use, the lead screw rotates under the drive of the driving motor, while the nut seats do not rotate. The two nut seats move closer to or away from each other along the first direction X, thereby driving the two supporting seats 320 to move closer to or away from each other.

[0082] In some embodiments, a second slide rail 211 is provided on the lifting seat 210. The second slide rail 211 extends along the first direction X and is fixedly connected to the lifting seat 210. In addition, two second sliders 212 are provided on the second slide rail 211. The two second sliders 212 are both slidably connected to the second slide rail 211. One second slider 212 is connected to one of the supporting seats 320, and the other second slider 212 is connected to the other supporting seat 320.

[0083] During use, the supporting seat 320 is slidably arranged on the lifting seat 210 through the second slide rail 211 and the second slider 212. When the two supporting seats 320 move closer to or away from each other, the second slide rail 211 and the second slider 212 limit and guide the supporting seat 320, so that the supporting seat 320 moves smoothly.

[0084] Furthermore, the pitch-changing mechanism 300 further includes a plurality of first buffer members 330. The plurality of first buffer members 330 are all connected to the lifting seat 210. One first buffer member 330 is located on one side of the supporting seat 320 along the first direction X, and the other first buffer member 330 is located on the other side of the supporting seat 320 along the first direction X.

[0085] Understandably, for each support base 320, at least two first buffer members 330 are provided correspondingly. At least one buffer member is located on one side of the support base 320 along the first direction X, and at least one buffer member is located on the other side of the support base 320 along the first direction X.

[0086] During use, the first buffer member 330 can buffer the support base 320 when the variable pitch driving member 310 drives the support base 320 to move, avoiding hard contact and collision of the support base 320, thereby protecting the support base 320. In addition, the first buffer members 330 located on both sides of the support base 320 can limit the moving range of the support base 320.

[0087] Optionally, the first buffer member 330 adopts structures such as rubber and springs, and buffers the support base 320 by elastically abutting against the support base 320.

[0088] In this embodiment, two first buffer members 330 are provided correspondingly for each support base 320. One first buffer member 330 is located on one side of the corresponding support base 320 along the first direction X, and the other first buffer member 330 is located on the other side of the corresponding support base 320 along the first direction X.

[0089] Please refer to Figure 3 and Figure 8 In some embodiments, the above-mentioned elevator 10 further includes a conveying mechanism 500, and the conveying mechanism 500 includes a conveyor belt 510 and a conveying driving member 520.

[0090] Among them, the conveyor belt 510 is arranged on the support base 320. The support base 320 carrying the tooling plate 30 specifically means that the conveyor belt 510 carries the tooling plate 30.

[0091] The conveying driving member 520 is connected to the lifting seat 210. The conveying driving member 520 is connected to the conveyor belt 510 and drives the conveyor belt 510 to move.

[0092] When the conveying driving member 520 drives the conveyor belt 510 to move, the conveyor belt 510 drives the tooling plate 30 to move along the second direction Y by using the friction force with the tooling plate 30, so that the tooling plate 30 enters the elevator 10 from one layer of the conveying line 20, or the tooling plate 30 leaves the elevator 10 and enters another layer of the conveying line 20. Among them, the second direction Y is perpendicular to the first direction X.

[0093] Specifically, the conveying driving member 520 includes a transmission link 521, a conveying motor 522 and a transmission sprocket 523. Correspondingly, the conveyor belt 510 is a chain belt.

[0094] Among them, the transmission connecting rod 521 extends along the first direction X and is rotatably connected to the lifting seat 210. The shaft of the transmission motor 522 is connected to the transmission connecting rod 521 to drive the transmission connecting rod 521 to rotate. The transmission sprocket 523 is sleeved on the transmission connecting rod 521 and is key-connected to the transmission connecting rod 521. In addition, the conveyor belt 510 is wound around the transmission sprocket 523 and meshes with the transmission sprocket 523.

[0095] During use, the transmission connecting rod 521 rotates under the drive of the transmission motor 522, drives the transmission sprocket 523 to rotate, and further drives the conveyor belt 510 to move.

[0096] Considering that the conveyor belt 510 is arranged on the support seat 320, and the two support seats 320 will approach or move away from each other during use, the transmission sprocket 523 is also slidably matched with the transmission connecting rod 521.

[0097] Optionally, the shaft of the transmission motor 522 is connected to the transmission connecting rod 521 through a sprocket-chain group to drive the transmission connecting rod 521 to rotate.

[0098] Furthermore, the pitch-changing mechanism 300 further includes a first detection member 340. The first detection member 340 is connected to the support seat 320 and is electrically connected to the transmission driving member 520. When the first detection member 340 detects the tooling plate 30, it outputs a signal to the transmission driving member 520 to cause the transmission driving member 520 to stop driving the conveyor belt 510.

[0099] For example, when the conveyor belt 510 drives the tooling plate 30 to move so that the tooling plate 30 completely enters the elevator 10, the first detection member 340 detects the tooling plate 30 and outputs a signal to the transmission driving member 520, causing the transmission driving member 520 to stop driving the conveyor belt 510 and further stop conveying the tooling plate 30.

[0100] In contrast, the traditional elevator 10 does not have detection of the arrival of the tooling plate 30. When the tooling plate 30 enters and exits the elevator 10, it is easy to collide with the machine, resulting in damage to the battery pack or its components.

[0101] Please refer to again Figure 4 , in this embodiment, the jacking driving member 410 adopts a jacking cylinder. The cylinder body of the jacking cylinder is connected to the bottom surface of the lifting seat 210. The piston rod of the jacking cylinder extends vertically upward, and the piston rod of the jacking cylinder passes through the lifting seat 210 and is connected to the bottom surface of the jacking seat 420.

[0102] In addition, the rotating mechanism 400 further includes a connecting member 460. The positioning seat 430 is rotatably arranged on the jacking seat 420 through the connecting member 460.

[0103] Exemplarily, the connecting member 460 may adopt a slewing bearing, which has an outer ring and an inner ring that can rotate relative to each other. Among them, the outer ring of the slewing bearing is fixedly connected to the top surface of the lifting seat 420, and the inner ring of the slewing bearing is fixedly connected to the bottom surface of the positioning seat 430.

[0104] On this basis, a gear ring is provided on the inner ring of the slewing bearing. Correspondingly, the rotary driving member 440 adopts a rotary motor, and a gear meshing with the gear ring is sleeved on the shaft of the rotary motor. The rotary motor is connected to the positioning seat 430 through the gear, the gear ring and the inner ring of the slewing bearing.

[0105] During use, the rotary motor drives the gear to rotate, the gear drives the gear ring to rotate, the gear ring further drives the inner ring of the slewing bearing to rotate, and finally drives the positioning seat 430 to rotate.

[0106] Furthermore, the rotating mechanism 400 further includes a second buffer member 450, and the second buffer member 450 is disposed between the lifting seat 210 and the lifting seat 420.

[0107] When the lifting driving member 410 drives the lifting seat 420 to descend and makes the lifting seat 420 approach the lifting seat 210, the second buffer member 450 can reduce the impact and vibration received by the lifting seat 420, thereby protecting the lift 10 and the workpiece from damage and improving the working efficiency and stability of the lift 10.

[0108] Optionally, the second buffer member 450 adopts structures such as rubber and springs, and the second buffer member 450 is connected to the top surface of the lifting seat 210 and forms a buffer for the lifting seat 420 by elastically abutting against the lifting seat 420.

[0109] Furthermore, a guide post 421 is connected to the bottom surface of the lifting seat 420. The guide post 421 extends in the vertical direction and slidably penetrates through the lifting seat 210.

[0110] During the process of the lifting driving member 410 driving the lifting seat 420 to lift and lower, the guide post 421 can limit and guide the lifting seat 420, so that the lifting seat 420 can lift and lower more smoothly.

[0111] Exemplarily, the number of the guide posts is four, and the four guide posts 421 are respectively connected to the apexes of the bottom surface of the lifting seat 420.

[0112] Furthermore, a positioning pin 431 is provided on the positioning seat 430. The positioning pin 431 is inserted into the tooling plate 30 when the lifting seat 420 rises to position the tooling plate 30.

[0113] When the lifting seat 420 is raised, the positioning pin 431 is inserted into the tooling plate 30, so that the tooling plate 30 and the positioning seat 430 remain relatively fixed in the horizontal direction, thereby ensuring that the tooling plate 30 and the positioning seat 430 rotate synchronously and can stably change the direction of the tooling plate 30.

[0114] Exemplarily, there are four positioning pins 431 , and the four positioning pins 431 are respectively connected to the top corners of the top surface of the positioning seat 430 .

[0115] When the above-mentioned elevator 10 is used, the lifting drive 220 first drives the lifting seat 210 to rise and fall to the feeding position 110. On this basis, the tooling board 30 after the previous process enters the elevator 10 from one layer of the conveyor line 20 and is carried by the end of the conveyor belt 510 close to the conveyor line 20. At the same time, the conveyor drive 520 drives the conveyor belt 510 to move, thereby driving the tooling board 30 to move, until the first detection component 340 detects the tooling board 30, so that the tooling board 30 completely enters the elevator 10.

[0116] Subsequently, the lifting drive 220 drives the lifting seat 210 to rise to the rotation position. The lifting drive 410 drives the lifting seat 420 to rise, driving the positioning seat 430 to rise. As the positioning seat 430 rises, the positioning pin 431 on the positioning seat 430 is plugged into the tooling plate 30 to position the tooling plate 30. After the positioning seat 430 rises further, it carries the tooling plate 30 and makes the tooling plate 30 separate from the support seat 320. On this basis, the rotating drive 440 drives the positioning seat 430 to rotate, driving the tooling plate 30 to rotate 90°. At the same time, the variable pitch drive 310 drives the two support seats 320 to slide in the direction of approaching or moving away from each other along the first direction X, so that the distance between the two support seats 320 is adapted to the size of the tooling plate 30 after rotation along the first direction X. Then, the lifting drive 410 drives the lifting seat 420 to descend, thereby driving the positioning seat 430 to descend, so that the tooling plate 30 is again carried by the support seat 320 after the pitch is changed.

[0117] Finally, the lifting drive 220 drives the lifting seat 210 to lift to the discharge position 120. On this basis, the conveying drive 520 drives the conveyor belt 510 to move in the reverse direction, thereby driving the tooling plate 30 to move in the reverse direction, sending the tooling plate 30 out of the elevator 10 and transferring it to another layer of the conveyor line 20, and then conveying it to the next process.

[0118] During this process, under the action of the rotating mechanism 400, the orientation of the tooling plate 30 can be changed, so that while realizing the reflow of the tooling plate 30, it can adapt to the different orientations of the tooling plate 30 in the previous and next processes.

[0119] Understandably, the pitch-changing mechanism 300 can cooperate with the rotating mechanism 400 to stably support the tooling plate 30 before and after the orientation of the tooling plate 30 changes. Alternatively, the pitch-changing mechanism 300 can also be used without cooperating with the rotating mechanism 400. By changing the distance between the two support seats 320, it can adapt to different models of tooling plates 30, so as to quickly change the model according to different scenarios and production line requirements and meet various change model requirements.

[0120] In addition, by adding the first detection member 340 and the second detection member 230, the above-mentioned elevator 10 can not only detect whether the tooling plate 30 has moved into place when the tooling plate 30 enters the elevator 10, avoid the tooling plate 30 hitting the machine, and further avoid bruising of the battery pack or its components, but also detect whether the lifting seat 210 has reached the lifting position when the lifting seat 210 is lifted or lowered, avoid the tooling plate 30 flowing into the elevator 10 when the lifting seat 210 is not in the feeding position 110, and avoid the tooling plate 30 leaving the elevator 10 when the lifting seat 210 is not in the discharging position 120, thereby avoiding the tooling plate 30 crashing. Thus, the above-mentioned elevator 10 has higher safety, reduces the accident risk, and reduces equipment failures.

[0121] In summary, the above-mentioned elevator 10 has high working efficiency, can quickly and accurately complete the lifting task, realize the transfer of the tooling plate 30 between any two layers of the conveyor line 20, reduces the labor intensity of manual handling, and is more convenient and easier.

[0122] Please refer to Figure 9 and Figure 10 This embodiment further provides a material conveying system, including a conveyor line 20 and the above-mentioned elevator 10. Among them, the conveyor line 20 conveys the tooling plate 30 to the elevator 10.

[0123] Exemplarily, the conveyor line 20 adopts a double-speed chain, which has an upper layer and a lower layer capable of conveying the tooling plate 30. The upper layer of the double-speed chain corresponds to the feeding position 110 of the rack 100, and the lower layer of the double-speed chain corresponds to the discharging position 120 of the rack 100.

[0124] During use, the upper layer of the double-speed chain conveys the tooling plate 30 along the first direction X until the tooling plate 30 moves to the elevator 10, and then conveys the tooling plate 30 to the elevator 10 along the second direction Y. After the tooling plate 30 enters the elevator 10, the elevator 10 adjusts the orientation of the tooling plate 30, drives the tooling plate 30 to lift and lower, and finally sends the tooling plate 30 into the lower layer of the double-speed chain to realize the return flow of the tooling plate 30.

[0125] In some embodiments, a jacking mechanism 21, a first blocking mechanism 22, and a second blocking mechanism 23 are provided on the conveyor line 20.

[0126] The lifting mechanism 21 is arranged corresponding to the elevator 10. The first blocking mechanism 22 is arranged on one side of the lifting mechanism 21 along the first direction X, and in the conveying direction of the conveying line 20, the first blocking mechanism 22 is located in front of the lifting mechanism 21. The second blocking mechanism 23 is arranged on one side of the lifting mechanism 21 along the second direction Y toward the elevator 10.

[0127] When the tooling board 30 moves to the elevator 10 under the conveyance of the conveyor line 20 , the first blocking mechanism 22 blocks the tooling board 30 , so that the tooling board 30 cannot continue to move forward along the first direction X with the conveyor line 20 . At this time, the tooling board 30 is just above the lifting mechanism 21 .

[0128] Then, the lifting mechanism 21 lifts the tooling board 30 to make the tooling board 30 leave the conveyor line 20. At the same time, the second blocking mechanism 23 is opened, allowing the lifting mechanism 21 to convey the tooling board 30 to the elevator 10 along the second direction Y until the tooling board 30 is carried by the conveyor belt 510.

[0129] After the tooling plate 30 completely enters the elevator 10 driven by the conveyor belt 510 , the second blocking mechanism 23 is closed to prevent multiple tooling plates 30 from entering the elevator 10 at the same time.

[0130] Please combine Figure 11 Specifically, the lifting mechanism 21 includes a roller 21 a that can be raised and lowered and rotated, and the roller 21 a carries the tooling plate 30 .

[0131] When the tooling board 30 is located above the lifting mechanism 21, the roller 21a rises to lift the tooling board 30, so that the tooling board 30 is separated from the conveyor line 20. Subsequently, the roller 21a starts to rotate and transports the tooling board 30 to the elevator 10 along the second direction Y.

[0132] Exemplarily, the roller 21a is rotatably arranged on a bracket. A motor is arranged on the bracket, and the motor drives the roller 21a to rotate through a sprocket and a chain. In addition, a cylinder is arranged on the line body of the conveyor line 20, and the cylinder lifts the bracket upward, thereby driving the roller 21a to rise.

[0133] Specifically, the first blocking mechanism 22 is composed of a first blocking member 22a and a first blocking cylinder 22b. The first blocking member 22a is rotatably connected to the body of the conveying line 20, and the rotation axis 222 of the first blocking member 22a is horizontal. The cylinder body of the first blocking cylinder 22b is fixedly connected to the body of the conveying line 20, and the piston rod of the first blocking cylinder 22b is connected to one end of the first blocking member 22a.

[0134] During use, the piston rod of the first blocking cylinder 22b extends and retracts to drive the first blocking member 22a to rotate, so that the other end of the first blocking member 22a swings up and down, and the other end of the first blocking member 22a can block the tooling plate 30 when it tilts upward.

[0135] Specifically, the second blocking mechanism 23 is composed of a second blocking member 23a and a second blocking cylinder 23b. The second blocking member 23a is slidably connected to the body of the conveying line 20 along the first direction X. The cylinder body of the second blocking cylinder 23b is fixedly connected to the body of the conveying line 20, and the piston rod of the second blocking cylinder 23b is connected to the second blocking member 23a.

[0136] During use, the piston rod of the second blocking cylinder 23b extends to drive the second blocking member 23a to move between the lifting mechanism 21 and the elevator 10, thereby blocking the tooling plate 30 from entering the elevator 10. Conversely, when the piston rod of the second blocking cylinder 23b retracts, the tooling plate 30 is allowed to enter the elevator 10.
