[0020] The elastic piece is arranged between the driving rod and the sliding seat, and the driving rod and the sliding seat have an elastic interaction force in the first direction; when the driving rod moves in a forward direction of the first direction, the interaction force is used for pushing the sliding seat to move in a forward direction of the first direction.

[0021] The movement of the driving rod in the first direction is used for driving the first pushing block to rotate, the movement of the sliding seat in the first direction is used for driving the second pushing block to rotate, and the rotation of the first pushing block and the second pushing block is used for jointly pushing the material box against the side pushing stopper.

[0022] In one of the technical solutions, the transmission module further comprises a clamping block which is relatively fixed to the driving rod, and the clamping block is arranged on a side of the sliding seat which is away from the power piece; when the driving rod moves linearly in a reverse direction of the first direction for resetting, the clamping block is used for pulling the sliding seat to move in a reverse direction of the first direction.

[0023] In one of the technical solutions, the loading mechanism comprises a first linear module, a second linear module, a third linear module, and a material taking mechanism which are sequentially connected.

[0024] The material taking mechanism is used for grabbing the material to be loaded at the feeding module and rotating the material to be loaded to a preset loading posture, and the first linear module, the second linear module, and the third linear module are used for jointly driving the material taking mechanism to move to the feeding module or the positioning device.

[0025] Compared with the prior art, the sorting machine provided by the application has at least the following beneficial effects:

[0026] During operation, the feeding module transports the materials to be loaded (e.g., material boxes) to a preset position. Simultaneously, the conveying mechanism moves the material box to a lifting station. The lifting mechanism then raises the material box from the lifting station to a positioning device. The positioning device calibrates the position of the material box. Next, the loading mechanism loads the materials from the feeding module into the calibrated material box. Once the material box is full, the lifting mechanism lowers the full material box and returns it to the conveying mechanism, which then transports the full material box to the designated position. This solution automatically completes the sorting and packing of material boxes, significantly improving packing efficiency. Attached Figure Description

The positioning device 5 is used to calibrate the position of the magazine, so that the feeding mechanism 8 can accurately load the magazine at the second conveying belt 62 into the inside of the magazine at the positioning device 5. In addition, when the magazine at the positioning device 5 is full of magazines, the lifting mechanism 2 is also used to drive the full magazine to be lowered and placed back on the conveying mechanism 1. Therefore, the conveying mechanism 1 is not only used to convey the empty magazine, but also used to convey the full magazine to be unloaded to a designated position.

[0067] Please refer to Figure 1 and Figure 4The loading mechanism 8 comprises a first linear module 81, a second linear module 82, a third linear module 83 and a material taking mechanism 84 connected in sequence, wherein the first linear module 81 is used to drive the second linear module 82, the third linear module 83 and the material taking mechanism 84 to move linearly on the Y axis together, the second linear module 82 is used to drive the third linear module 83 and the material taking mechanism 84 to move linearly on the X axis together, the third linear module 83 is used to drive the material taking mechanism 84 to move linearly in the vertical direction, and the material taking mechanism 84 is used to grab the magazine at the feeding module 6 and rotate the magazine to a preset loading posture. Through the three-axis linkage of the first linear module 81, the second linear module 82 and the third linear module 83, the material taking mechanism 84 can be driven to move to the feeding module 6 or the positioning device 5, thereby realizing the function of loading the magazine at the feeding module 6 into the inside of the magazine at the positioning device 5 in the preset loading posture. The first linear module 81, the second linear module 82 and the third linear module 83 can be a lead screw module, a synchronous belt module or a linear motor, etc. Specifically, the material taking mechanism 84 comprises a connecting seat 841, a telescopic air cylinder 842, a rotating seat 843 and a clamping jaw 844, the clamping jaw 844 is used to clamp the magazine in a pneumatic manner, the connecting seat 841 is connected to the third linear module 83, the cylinder body of the telescopic air cylinder 842 is rotationally connected to the connecting seat 841, the piston rod of the telescopic air cylinder 842 is rotationally connected to the rotating seat 843, the rotating seat 843 is also rotationally connected to the connecting seat 841, the clamping jaw 844 is installed on the rotating seat 843, and the telescopic air cylinder 842 can drive the rotating seat 843 and the clamping jaw 844 to rotate relative to the connecting seat 841 through the telescopic sliding of the piston rod, thereby driving the magazine on the clamping jaw 844 to rotate to a preset loading posture. In this embodiment, the magazine needs to be rotated by 90° before being put into the magazine at the positioning device 5, that is, the telescopic air cylinder 842 is used to drive the clamping jaw 844 to rotate by 90°.

[0068] Please refer to Figure 5 to Figure 8 The stacking mechanism 4 specifically comprises a rack 41, a material supporting mechanism 42 and two material lifting mechanisms 43. The rack 41 is provided with a stacking area 44 for stacking a plurality of magazines in the vertical direction, so that the rack 41 has the function of storing magazines. The material supporting mechanism 42 is arranged directly below the stacking area 44 and is used to support the bottommost magazine in the stacking area 44 and put the supported magazine onto the conveying mechanism 1. The two material lifting mechanisms 43 are arranged on opposite sides of the stacking area 44 and are used to jointly lift the second last magazine at the bottom position of the stacking area 44. Specifically, when the two material lifting mechanisms 43 do not lift the second last magazine of the stacking area 44, the material supporting mechanism 42 supports all the magazines in the stacking area 44; when the two material lifting mechanisms 43 have lifted the second last magazine of the stacking area 44, the material supporting mechanism 42 only supports the bottommost magazine in the stacking area 44.

[0070] Please refer to Figure 6 , the conveying mechanism 1 of the embodiment is preferably a drum conveying line, the conveying mechanism 1 specifically comprises a frame body 11 and a plurality of drums 12, the plurality of drums 12 are arranged in sequence and at intervals along a direction, there is a gap 13 between each two adjacent drums 12, and the plurality of drums 12 are respectively rotatably connected with the frame body 11, the plurality of drums 12 can be simultaneously driven to rotate by a chain, and the rotation of the drums 12 is used to drive the material 9 to transport and advance to a desired position. Based on the structure design that the conveying mechanism 1 adopts a drum conveying line, the supporting block 422 of the material supporting mechanism 42 of the embodiment is arranged at the gap 13 between each two adjacent drums 12, when the supporting block 422 ascends to the highest position, the supporting block 422 is higher than the drums 12, so that the supporting block 422 can support the last one of the material boxes in the stacking area 44, and when the supporting block 422 descends to the lowest position, the supporting block 422 is lower than the upper surface of the drums 12, so that the supporting block 422 can place the supported material box on the conveying mechanism 1.

[0071] In the embodiment, in order to further improve the stability of the material box placed on the conveying mechanism 1, please refer to Figure 6 , one material supporting mechanism 42 is also arranged outside the conveying mechanism 1, through the common support of the two material supporting mechanisms 42, the last one of the material boxes in the stacking area 44 can be reliably placed on the conveying mechanism 1, and when the second last one of the material boxes in the stacking area 44 is not lifted by the two material lifting mechanisms 43, the two material supporting mechanisms 42 can also stably support all the material boxes in the stacking area 44, so as to avoid the problem that the material boxes are unstable due to the support of only a single material supporting mechanism 42. In other embodiments, a material supporting mechanism 42 can also be arranged in each of the two gaps 13, so as to achieve the above-mentioned effect.

[0072] Please refer to Figure 6 and Figure 7The lifting mechanism 43 specifically comprises a first driver 431, a moving seat 432, a second driver 433 and a gripper 434, wherein the gripper 434 is installed on the moving seat 432 through a rotating shaft 435, realizing the rotating connection of the gripper 434 and the moving seat 432, the axis of the rotating shaft 435 points to a first direction, the first direction is parallel to the X axis, the second driver 433 is connected with the moving seat 432 and the gripper 434 respectively, and the second driver 433 is used to drive the gripper 434 to rotate upward or downward relative to the moving seat 432. The first driver 431 is connected with the rack 41 and the moving seat 432 respectively, and the first driver 431 is used to drive the moving seat 432, the second driver 433 and the gripper 434 to ascend or descend in the vertical direction. In order to improve the moving precision of the gripper 434, a guide rod or a guide rail can be connected between the moving seat 432 and the rack 41. Specifically, the first driver 431 and the second driver 433 are both preferably air cylinders, and the second driver 433 specifically comprises a cylinder body 4331 and a piston rod 4332 which are connected in sliding mode, the end of the cylinder body 4331 away from the piston rod 4332 is rotatably connected with the moving seat 432, and the axis of the rotation of the cylinder body 4331 relative to the moving seat 432 is parallel to the first direction. A limiting hole 4321 is formed through the moving seat 432, and the gripper 434 is rotatably connected with the end of the piston rod 4332 away from the cylinder body 4331 through the limiting hole 4321, and the axis of the rotation of the gripper 434 relative to the piston rod 4332 is also parallel to the first direction. When the piston rod 4332 of the second driver 433 extends or retracts relative to the cylinder body 4331, the piston rod 4332 can drive the gripper 434 to rotate relative to the moving seat 432, so that the gripper 434 can abut against the outer wall of the material 9. In this process, the piston rod 4332 will rotate slightly relative to the gripper 434, and at the same time, the cylinder body 4331 will rotate slightly relative to the moving seat 432. The limiting hole 4321 plays a role in avoiding the gripper 434 to enable the gripper 434 to be connected with the second driver 433, and also plays a role in limiting the rotation angle of the gripper 434. Through the common rotation of the grippers 434 of the two lifting mechanisms 43, the rack can be clamped and lifted upward. Of course, in another embodiment, the cylinder body 4331 can also be rotatably connected with the gripper 434, and correspondingly, the piston rod 4332 needs to be rotatably connected with the moving seat 432. At this time, the extension and retraction sliding of the piston rod 4332 relative to the cylinder body 4331 can also realize the function of driving the gripper 434 to rotate. In addition, a soft buffer pad 436 is sleeved on the outer wall of the gripper 434, which can avoid the scratch of the gripper 434 and the rack due to the hard collision between them, and also can increase the contact area between the gripper 434 and the rack, so as to ensure that the rack can be reliably lifted upward by the gripper 434.

[0073] Please see Figure 5 to Figure 7The conveying mechanism 1 of the embodiment is provided with a receiving station 17, which is arranged directly below the stacking area 44. The receiving station 17 is used to receive the boxes placed down by the box supporting mechanism 42. The boxes can be guided by the guide plates when gradually placed into the receiving station 17, so as to ensure that the boxes can accurately fall into the receiving station 17. In addition, the bottom of the rack 41 can be fixed with a code scanner and a sensor. The code scanner is directed to the receiving station 17 and is used to identify the electronic information (such as a two-dimensional code or a bar code) on the surface of the box at the receiving station 17. The sensor is used to identify whether the box at the receiving station 17 is sent out under the driving of the conveying mechanism 1.

[0074] The working principle of the stacking mechanism 4 can be summarized as follows:

[0075] Before work, a plurality of boxes can be placed into the stacking area 44 in advance, so that the plurality of boxes are stacked in the vertical direction at the stacking area 44. At this time, the supporting blocks 422 of the box supporting mechanism 42 located below the stacking area 44 are higher than the conveying mechanism 1. At this time, the supporting blocks 422 support all the stacked boxes.

[0076] When working, the second drivers 433 of the two box lifting mechanisms 43 drive the corresponding grippers 434 to rotate, so that the grippers 434 of the two box lifting mechanisms 43 can jointly lift the second last box at the bottom position of the stacking area 44 upward. At this time, the supporting blocks 422 of the box supporting mechanism 42 only support the bottom box of the stacking area 44, and the other boxes in the stacking area 44 have been lifted upward. Then, the actuator 421 of the box supporting mechanism 42 drives the supporting blocks 422 to descend, and the supporting blocks 422 place the supported box on the receiving station 17 of the conveying mechanism 1. Then, the code scanner scans the box at the receiving station 17. After the scanning is completed, the conveying mechanism 1 conveys the box at the receiving station 17 to each waiting lifting station 10. When the sensor detects that the box at the receiving station 17 is sent out by the conveying mechanism 1, the actuator 421 of the box supporting mechanism 42 drives the supporting blocks 422 to move upward to the reset position. Then, the first drivers 431 of the two box lifting mechanisms 43 drive the corresponding grippers 434 to descend, so that all the lifted boxes can gradually approach the supporting blocks 422. Then, the second drivers 433 of the two box lifting mechanisms 43 drive the corresponding grippers 434 to rotate to the initial position, so that the grippers 434 release the clamped boxes. The stacked boxes will fall onto the box supporting mechanism 42 due to gravity. At this time, the box supporting mechanism 42 again supports the plurality of boxes of the stacking area 44. The above working process is sequentially cycled, so as to realize the automatic feeding function of the boxes.

[0077] Please refer to Figure 13The lifting mechanism 2 comprises a base 21, a driving module 22 and a lifting seat 23, wherein the base 21 can be connected to the same rack as the conveying mechanism 1, or the two can be separately arranged on the ground. The driving module 22 is connected to the base 21 and the lifting seat 23 respectively, and is used to drive the lifting seat 23 to move in the vertical direction relative to the base 21. The lifting seat 23 specifically comprises a material supporting member 231 and two guide plates 232, the material supporting member 231 is used to support the material box, when the lifting seat 23 moves upward under the driving of the driving module 22, the material supporting member 231 can lift the material on the lifting position 10 to the positioning device 5, and one of the two guide plates 232 is fixed above the material supporting member 231, and the other is fixed below the material supporting member 231, when the lifting seat 23 moves in the vertical direction to the preset position, one of the two guide plates 232 is located on one side of the conveying mechanism 1, and the guide plate 232 is used to guide the material on the conveying mechanism 1 to move forward.

[0078] Please refer again to Figure 13 The guide plate 232 comprises a first guide slope 2321, a limiting surface 2322 and a second guide slope 2323 connected in sequence along the conveying direction of the conveying mechanism 1, wherein the limiting surface 2322 is parallel to the conveying direction of the conveying mechanism 1, the first guide slope 2321 and the limiting surface 2322 and the second guide slope 2323 and the limiting surface 2322 are all arranged at an angle, and the first guide slope 2321 and the second guide slope 2323 extend away from the conveying mechanism 1 relative to the limiting surface 2322, the first guide slope 2321 is used to guide the material on the conveying mechanism 1 to move more accurately onto the material supporting member 231, the limiting surface 2322 is used to prevent the material from falling to the side during conveying, and the second guide slope 2323 is used to guide the material to be sent out along the conveying direction of the conveying mechanism 1.

[0079] Specifically, the path of the lifting seat 23 moving in the vertical direction includes a first position and a second position above the first position, when the lifting seat 23 moves to the first position, the material supporting member 231 is below the conveying mechanism 1, and a piece of the flow guide plate 232 above the material supporting member 231 is located at one side of the conveying mechanism 1, at this time, the material box on the waiting lifting station 10 can be accurately moved to the directly above of the material supporting member 231 under the guidance of the flow guide plate 232; in the process of the lifting seat 23 moving from the first position to the second position, the material supporting member 231 will lift the material box and drive the material box to rise to the positioning device 5; when the lifting seat 23 moves to the second position, the material supporting member 231 is above the conveying mechanism 1, and a piece of the flow guide plate 232 below the material supporting member 231 is located at one side of the conveying mechanism 1, at this time, the material box on the conveying mechanism 1 can continue to transport forward by crossing an adjacent lifting mechanism 2 under the guidance of the flow guide plate 232, the material box which continues to transport forward will not deviate under the guidance of the flow guide plate 232, ensuring that other material boxes on the conveying mechanism 1 can cross the lifting mechanism 2 and be reliably conveyed to the corresponding waiting lifting station 10 or directly discharged outward.

[0080] Please refer again to Figure 13The material supporting member 231 comprises a sliding base 2311 and two supporting rods 2312, both of which are fixed on the same side of the sliding base 2311, the sliding base 2311 is used for sliding connection with the base 21 in the vertical direction, the base 21 is fixed with two guide rods 24, the axial direction of the guide rods 24 is parallel to the vertical direction, both ends of the sliding base 2311 are sleeved on a corresponding one of the guide rods 24 through linear bearings and can slide along the axial direction of the guide rod 24, the guide rod 24 is used for guiding to improve the sliding accuracy of the sliding base 2311. The two supporting rods 2312 are used for jointly supporting the material box, when the supporting rods 2312 are driven by the driving module 22 to move upward, the two supporting rods 2312 can jointly support the material box. The two guide plates 232 are both fixed on the sliding base 2311 and located on one side of the length direction of the two supporting rods 2312, and one of the guide plates 232 is arranged above the two supporting rods 2312, and the other guide plate 232 is arranged below the two supporting rods 2312. Specifically, when one of the guide plates 232 above the material supporting member 231 is located on one side of the conveying mechanism 1, one of the supporting rods 2312 in the material supporting member 231 is arranged in one of the gaps 13, the other supporting rod 2312 in the material supporting member 231 is arranged in the other gap 13, and the length direction of the two supporting rods 2312 is parallel to the axial direction of the roller 12. In addition, in order to avoid that the supporting rods 2312 and the material may damage the material due to hard collision, the upper surface of the supporting rods 2312 is provided with a gasket 2313 for buffering, the gasket 2313 can be laid on the upper surface of the supporting rods 2312, or a soft buffer member can be used to wrap the entire supporting rods 2312, so that the upper surface of the supporting rods 2312 has the gasket 2313.

[0081] Please refer to Figure 13 The driving module 22 comprises a motor 221, a driving wheel (not shown in the figure), a driven wheel 222, a transmission belt 223 and a lead screw 224. The motor 221 is fixed on the top of the base 21, the driving wheel is sleeved on the output shaft of the motor 221, the driven wheel 222 is sleeved on the end of the lead screw 224, both ends of the lead screw 224 are rotatably connected with the base 21 through bearings, the lead screw 224 is arranged between the two guide rods 24 and the axial direction thereof is also parallel to the vertical direction, the lead screw 224 is threadedly connected with the above-mentioned sliding base 2311, and the transmission belt 223 is wound around the driving wheel and the driven wheel 222. When the motor 221 rotates, the transmission belt 223 drives the lead screw 224 to rotate, and the rotation of the lead screw 224 drives the sliding base 2311 to rise or fall in the vertical direction.

[0082] Please refer to Figure 9 and Figure 10The plurality of lifting mechanisms 2 are preferably arranged on the same side of the conveying mechanism 1 along the conveying direction of the conveying mechanism 1, and a baffle 14 is arranged on the other side of the conveying mechanism 1 opposite to the plurality of lifting mechanisms 2. The baffle 14 extends along the conveying direction of the conveying mechanism 1 and has a length almost the same as the total length of the plurality of lifting mechanisms 2. The baffle 14 is also used for guiding the flow. Through the combined guiding of the baffle 14 and any one of the flow guide plates 232 on the plurality of lifting mechanisms 2, the phenomenon that the material box deviates to both sides under the conveying of the conveying mechanism 1 can be avoided, and the material box can be accurately moved to the corresponding lifting position 10.

[0083] Please refer to Figure 10 and Figure 11 Based on the structure design that a plurality of lifting positions 10 are arranged on the conveying mechanism 1, the box feeding module 7 of the embodiment further comprises a plurality of material blocking mechanisms 3. The plurality of material blocking mechanisms 3 are arranged in sequence and at intervals along the conveying direction of the conveying mechanism 1, and each adjacent position of the lifting position 10 is provided with a material blocking mechanism 3. The material blocking mechanism 3 has a material blocking state for blocking the advancement of the material and a material releasing state for allowing the advancement of the material. Specifically, when the material blocking mechanism 3 is in the material releasing state, the material box can be moved to the corresponding lifting position 10 under the conveying of the conveying mechanism 1. When the material blocking mechanism 3 is in the material blocking state, the material box can be stopped at the corresponding lifting position 10. After the corresponding lifting mechanism 2 lifts the material box, the material blocking mechanism 3 can be switched back to the material releasing state, so that the material box on the conveying mechanism 1 can continue to advance and move to the corresponding lifting position 10.

[0084] Please refer to Figure 9 The baffle 14 is also used for mounting a plurality of sensors. Part of the plurality of sensors is a first sensor 15, and the other part is a second sensor 16. One first sensor 15 and one second sensor 16 are arranged on one side of each lifting position 10. The first sensor 15 is used for detecting whether the material box on the conveying mechanism 1 starts to enter the lifting position 10. When the first sensor 15 detects the material box, the first sensor 15 feeds back a signal to the corresponding material blocking mechanism 3, and the material blocking mechanism 3 can be switched to the material blocking state. The second sensor 16 is used for detecting whether the material box on the conveying mechanism 1 has completely entered the lifting position 10. When the second sensor 16 detects the material box, the second sensor 16 feeds back a signal to the corresponding lifting mechanism 2, and the driving module 22 of the lifting mechanism 2 drives the lifting seat 23 to rise to drive the material box to be lifted to the positioning device 5.

[0085] Please refer to Figure 10 and Figure 12The material blocking mechanism 3 specifically comprises a driving cylinder 31 and a blocking plate 32 connected with each other, the driving cylinder 31 drives the blocking plate 32 to move in the vertical direction, the blocking plate 32 extends upward from the gap 13 between the two rollers 12 when moving upward, and when the blocking plate 32 extends upward from the gap 13, it is the material blocking state of the material blocking mechanism 3, at this time, the material box can stay in the corresponding one of the waiting lifting stations 10 under the blocking of the blocking plate 32; when the blocking plate 32 moves downward from the gap 13 and does not expose upward relative to the rollers 12, it is the material releasing state of the material blocking mechanism 3, at this time, the material box can continue to advance under the driving of the conveying mechanism 1 and finally move to the corresponding waiting lifting station 10 due to the absence of the blocking of the blocking plate 32.

[0086] Please refer to Figure 14 The positioning device 5 comprises a side pushing mechanism 51, a forward pushing mechanism 52, a forward pushing blocking plate 53 and a side pushing blocking plate 54, wherein the side pushing mechanism 51, the forward pushing mechanism 52, the side pushing blocking plate 54 and the forward pushing blocking plate 53 jointly enclose a containing space 55, the lifting mechanism 2 lifts the material box to the containing space 55, the forward pushing mechanism 52 is opposite to the forward pushing blocking plate 53, and the side pushing mechanism 51 is opposite to the side pushing blocking plate 54, the forward pushing blocking plate 53 and the side pushing blocking plate 54 are taken as two references for positioning in the embodiment, the forward pushing mechanism 52 is used for pushing the material box in the containing space 55 to abut against the forward pushing blocking plate 53 along the reverse direction of the X axis, and the side pushing mechanism 51 is used for pushing the material box in the containing space 55 to abut against the side pushing blocking plate 54 along the Y axis. In addition, the deflector 232 can be taken as the forward pushing blocking plate 53 or the side pushing blocking plate 54.

[0087] Please refer to Figure 14 to Figure 22 The side pushing mechanism 51 specifically comprises a fixed seat 511, a power member 512, a transmission module 513, a first pushing block 514 and a second pushing block 515. The first pushing block 514 and the second pushing block 515 are rotationally connected with the fixed seat 511, the power member 512 is fixed on the fixed seat 511 and connected with the transmission module 513, the power member 512 is used for driving the transmission module 513 to move linearly along the first direction (i.e. the X axis direction in the figure) reciprocatingly, and the power member 512 is preferably a cylinder with low cost. The transmission module 513 is connected with the first pushing block 514 and the second pushing block 515 respectively, and the transmission module 513 is used for driving the first pushing block 514 and the second pushing block 515 to rotate relative to the fixed seat 511 when moving along the X axis direction, wherein the transmission module 513 and the second pushing block 515 can be flexibly connected. Figure 15 and Figure 16 The positions shown in Figs. 13 and 14 are initial positions of the first pushing block 514 and the second pushing block 515 before rotation, Figure 17 and Figure 20The first push block 514 and the second push block 515 are shown in the position after rotation, and the rotation of the first push block 514 and the rotation of the second push block 515 are used to jointly abut the material box on the side push baffle 54. When the first push block 514 and the second push block 515 are both abutted on the surface of the material box, the force of the second push block 515 pressing on the surface of the material box is designed to be greater than the force of the first push block 514 pressing on the surface of the material box.

[0088] The transmission module 513 specifically comprises a driving rod 5131, a sliding seat 5132, an elastic member 5133, and a clamping block 5134. The driving rod 5131 is connected with the output end of the power member 512, and can move linearly along the X-axis direction under the driving of the power member 512. The sliding seat 5132 is slidably connected with the fixed seat 511 along the X-axis direction. In the embodiment, a guide rail 516 and a sliding block 517 are connected between the sliding seat 5132 and the fixed seat 511. The sliding block 517 can slide freely on the guide rail 516. The length direction of the guide rail 516 is parallel to the X-axis. One of the guide rail 516 and the sliding block 517 is fixedly connected with the sliding seat 5132, and the other is fixedly connected with the fixed seat 511, so as to realize the sliding connection between the sliding seat 5132 and the fixed seat 511. In other embodiments, the sliding connection between the sliding seat 5132 and the fixed seat 511 can also be realized by using a guide rod structure. The clamping block 5134 is fixed on the driving rod 5131, and is arranged on the side of the sliding seat 5132 away from the power member 512. The elastic member 5133 is arranged between the driving rod 5131 and the sliding seat 5132. The elastic extension direction of the elastic member 5133 is parallel to the X-axis direction. The sliding seat 5132 is abutted on the clamping block 5134 under the action of the elastic member 5133. The elastic member 5133 enables the driving rod 5131 and the sliding seat 5132 to have an elastic interaction force in the X-axis direction. When the driving rod 5131 moves along the positive direction of the X-axis, the sliding seat 5132 also moves along the positive direction of the X-axis under the elastic action of the elastic member 5133. When the driving rod 5131 moves linearly along the negative direction of the X-axis under the driving of the power member 512, the clamping block 5134 can pull the sliding seat 5132 back along the negative direction of the X-axis. In other words, when the driving rod 5131 resets to the initial position along the negative direction of the X-axis, the clamping block 5134 is used to enable the sliding seat 5132 to also reset to the initial position along the negative direction of the X-axis.

[0089] The technical content of the above paragraph is more specifically supplemented. The first transmission rod 5135 is fixed on the driving rod 5131, the second transmission rod 5136 is fixed on the sliding seat 5132, the first recess 5141 is formed on the first push block 514, the second recess 5151 is formed on the second push block 515, part of the first transmission rod 5135 is inserted into the first recess 5141, and part of the second transmission rod 5136 is inserted into the second recess 5151. When the driving rod 5131 and the sliding seat 5132 move linearly together along the positive direction of the X axis, the first transmission rod 5135 will exert force on the groove wall of the first recess 5141 to make the first push block 514 rotate relative to the fixed seat 511 and push outwards, and at the same time, the second transmission rod 5136 will exert force on the groove wall of the second recess 5151 to make the second push block 515 rotate relative to the fixed seat 511 and push outwards. When the driving rod 5131 and the sliding seat 5132 move linearly together along the negative direction of the X axis, the first transmission rod 5135 will exert force on the groove wall of the first recess 5141 to make the first push block 514 rotate to the initial position, and at the same time, the second transmission rod 5136 will exert force on the groove wall of the second recess 5151 to make the second push block 515 rotate to the initial position. In addition, to avoid mutual scratching when the first transmission rod 5135 and the groove wall of the first recess 5141 contact each other, the first roller 5137 is sleeved on the first transmission rod 5135, at least part of the first roller 5137 is accommodated in the first recess 5141, and the outer circle of the first roller 5137 is used to directly contact the groove wall of the first recess 5141. When the first transmission rod 5135 drives the first push block 514 to rotate, the outer circle of the first roller 5137 will rotate to avoid scratching the groove wall of the first recess 5141. Similarly, to avoid mutual scratching when the second transmission rod 5136 and the groove wall of the second recess 5151 contact each other, the second roller 5138 is sleeved on the second transmission rod 5136, at least part of the second roller 5138 is accommodated in the second recess 5151, and the outer circle of the second roller 5138 is used to directly contact the groove wall of the second recess 5151. In addition, the size of the first recess 5141 is greater than the outer size of the first roller 5137, so that the first push block 514 can rotate when the first transmission rod 5135 moves linearly along the X axis. Similarly, the size of the second recess 5151 is greater than the outer size of the second roller 5138, so that the second push block 515 can rotate when the second transmission rod 5136 moves linearly along the X axis. In an embodiment, the first recess 5141 and the second recess 5151 are U-shaped grooves.In addition, in order to avoid the first pushing block 514 and the second pushing block 515 scratching the material, the first pushing block 514 is provided with a first pushing wheel 518 capable of freely rotating, and the second pushing block 515 is provided with a second pushing wheel 519 capable of freely rotating, the outer rings of the first pushing wheel 518 and the second pushing wheel 519 are used to directly contact the surface of the material box, so as to prevent the material box from being scratched by the pushing block.

[0090] Further, the second pushing block 515 is designed to press against the material box earlier than the first pushing block 514. Specifically, during the movement of the driving rod 5131 in the positive direction of the X axis under the driving of the power element 512, the elastic element 5133 drives the sliding seat 5132 to move in the positive direction of the X axis together with the driving rod 5131, in the process, the driving rod 5131 drives the first pushing block 514 to rotate and push outwards, and at the same time, the sliding seat 5132 drives the second pushing block 515 to rotate and push outwards, when the second pushing block 515 first presses against the surface of the material box, at this time, the second pushing block 515 cannot continue to rotate relative to the fixed seat 511 due to the reaction force of the material, and since the second pushing block 515 cannot rotate, the sliding seat 5132 at this time is in a static state relative to the fixed seat 511, that is, the sliding seat 5132 cannot continue to move in the positive direction of the X axis, since the elastic element 5133 capable of elastically deforming in the X axis direction is arranged between the driving rod 5131 and the sliding seat 5132, the driving rod 5131 can still continue to move in the positive direction of the X axis, until the driving rod 5131 drives the first pushing block 514 to also press against the surface of the material box, at this time, the function of the first pushing block 514 and the second pushing block 515 jointly pushing the material box to the side pushing baffle 54 is realized. The transmission module 513 adopting the technical solution can ensure that the first pushing block 514 and the second pushing block 515 can finally press against the material box at the same time, so as to ensure that the material box has high positioning accuracy, and avoid the problem that only one of the first pushing block 514 and the second pushing block 515 presses against the surface of the material box due to insufficient machining accuracy of the workpiece and poor assembly accuracy.

[0091] Further, the elastic element 5133 of the embodiment is preferably a compression spring, and correspondingly, the second pushing block 515 is arranged to be farther away from the power element 512 than the first pushing block 514. When the second pushing block 515 first presses against the surface of the material box and cannot continue to rotate relative to the fixed seat 511, the sliding seat 5132 also cannot continue to move in the positive direction of the X axis, but the driving rod 5131 which can still continue to move in the positive direction of the X axis gradually approaches the sliding seat 5132 by gradually compressing the elastic element 5133, and finally drives the first pushing block 514 to also press against the surface of the material box.

[0092] In other embodiments, the elastic member 5133 can use a tension spring, and correspondingly, the second push block 515 needs to be arranged closer to the power member 512 than the first push block 514. In operation, when the second push block 515 first presses against the surface of the material box and cannot continue to rotate relative to the fixed seat 511, the sliding seat 5132 also cannot continue to move in the positive direction of the X axis, but the drive rod 5131 that can still continue to move in the positive direction of the X axis will gradually move away from the sliding seat 5132 by gradually lengthening the elastic member 5133, and finally drive the first push block 514 to also press against the surface of the material box.

[0093] Based on the structure design of the elastic member 5133 using a compression spring in the embodiment, the drive rod 5131 is preferably designed to penetrate the sliding seat 5132 in the first direction, the elastic member 5133 is sleeved on the drive rod 5131, and the clamping block 5134 is fixed at the end position of the drive rod 5131 away from the power member 512. In this way, the volume of the entire side pushing mechanism 51 can be smaller, so that the side pushing mechanism 51 can be applied to narrow spaces.

[0094] The driving rod 5131 and the sliding seat 5132 are both split into multiple components for ease of processing and assembly. Specifically, the driving rod 5131 includes a rod body 51311 and a first transmission block 51312 fixedly connected. The first transmission block 51312 is fixedly connected to the output end of the power member 512. The first transmission rod 5135 is fixed to the first transmission block 51312. The rod body 51311 extends through the entire sliding seat 5132 along the X-axis direction and extends outward. The clamping block 5134 is fixed to the end of the rod body 51311 away from the power member 512. The elastic member 5133 is sleeved on the outer wall of the rod body 51311. The sliding seat 5132 includes a sliding seat body 51321, a connecting plate 51322, and a second transmission block 51323 fixedly connected in sequence. The sliding seat body 51321 is slidably connected to the fixed seat 511 along the X-axis direction by using the guide rail 516 and the sliding block 517. The second transmission rod 5136 is fixed to the second transmission block 51323. The second transmission block 51323 is provided with an installation groove 513231. The installation groove 513231 is provided with a ring-shaped wear-resistant sleeve 51324. The groove bottom of the installation groove 513231 is provided with a limiting groove 513232. The elastic member 5133 is accommodated in the limiting groove 513232. One end of the elastic member 5133 abuts against the groove bottom of the limiting groove 513232. The other end of the elastic member 5133 abuts against the end face of the rod body 51311. The elastic member 5133 causes the second transmission block 51323 to abut against the clamping block 5134 at the end of the rod body 51311. The wear-resistant sleeve 51324 is sleeved on the outer wall of the rod body 51311. The rod body 51311 can freely slide along the inner circle of the wear-resistant sleeve 51324. In other words, the rod body 51311 is slidably connected to the second transmission block 51323 through the wear-resistant sleeve 51324, so as to ensure better movement accuracy when the rod body 51311 and the second transmission block 51323 move relative to each other along the X-axis direction, and avoid being stuck.

[0095] The side pushing mechanism 51 of the present technical solution can simultaneously drive the first pushing block 514 and the second pushing block 515 to abut against the surface of the material box by using only one power member 512, so as to accurately push the material box onto the side pushing baffle 54. In addition, the elastic member 5133 is arranged between the sliding seat 5132 and the second pushing block 515, so that when the first pushing block 514 and the second pushing block 515 abut against the surface of the material box, the force with which the second pushing block 515 abuts against the surface of the material box is greater than the force with which the first pushing block 514 abuts against the surface of the material box. Since the present solution only uses one power member 512, the production cost is greatly reduced. In addition, the components of the side pushing mechanism 51 of the present technical solution are mostly arranged along the X-axis direction, so the side pushing mechanism 51 of the present technical solution also has the advantage of saving space.

[0096] Please refer again to Figure 14 Since the length of the material box to be positioned in the Y-axis direction is short, the number of the forward pushing mechanism 52 used in the embodiment is one, and the forward pushing mechanism 52 specifically comprises a forward pushing cylinder 521 and a third pushing block 522 connected to each other, and the forward pushing cylinder 521 is used to drive the third pushing block 522 to extend or retract. In operation, the power element 512 of the side pushing mechanism 51 drives the driving rod 5131 to move along the X-axis, so that the first pushing block 514 and the second pushing block 515 are both rotated towards the direction of approaching the material box, and finally the first pushing wheel 518 and the second pushing wheel 519 jointly abut the material box on the side pushing stop plate 54 along the Y-axis direction, and then the forward pushing cylinder 521 of the forward pushing mechanism 52 drives the third pushing block 522 to extend, and the third pushing block 522 pushes the material box to abut on the forward pushing stop plate 53, thereby realizing the positioning function of the material.

[0097] In other embodiments, if the length of the material box to be positioned in the Y-axis direction is also long, the forward pushing mechanism 52 can also be selected to have the same structure as the side pushing mechanism 51, so that the material box can be accurately abutted on the forward pushing stop plate 53, thereby improving the positioning accuracy of the material box.
