[0038] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] like Figures 1 to 4 As shown, an embodiment of the present invention provides a pushing mechanism 100, including a driving member 1, a driving connecting member 2 and a pushing member 3, the pushing member 3 is connected to the driving connecting member 2, the output end of the driving member 1 is connected to the driving connecting member 2, the driving member 1 is used to drive the driving connecting member 2 to move along the first direction, so that the pushing member 3 can drive the material sheet in the material box 200 to move along the guide member 202 on the material box 200, thereby pushing the material sheet out of the material box 200.

[0040] The driving connecting member 2 is used to slide with the guide member 202 to guide the driving connecting member 2 when the driving member 1 drives the driving connecting member 2 to move.

[0041] When the driving member 1 drives the driving connecting member 2 to move, the driving connecting member 2 can slide on the guide member 202, so that the driving connecting member 2 can be accurately guided to ensure that the driving connecting member 2 always moves along the preset direction, prevent the driving connecting member 2 from deviating during the pushing process, and ensure that the material plate can be accurately pushed out of the material box 200 and enter the next processing link. The guide member 202 in the material box is set to guide the movement of the material plate in the material box. The guide member 202 can also guide the driving connecting member 2 when the driving connecting member 2 pushes the material. There is no need to set up a channel to accommodate the driving connecting member, which causes too much space in the material box 200 to be occupied, and can simplify the design and assembly difficulty of the material box.

[0042] The material plate is a PCB, and a pin is provided on the PCB. The guide member 202 on the material box 200 is limited by two guide plates, and the two guide plates are arranged at intervals to form a guide groove. When the PCB is pushed by the pushing member 3, the pin can move along the guide groove, thereby allowing the PCB to move along the guide member 202.

[0043] In one embodiment, if Figure 1 As shown, the driving connector 2 includes a first side plate 21, a second side plate 22, and a plurality of connecting members 23. The first side plate 21 and the second side plate 22 are arranged relative to each other along the second direction. The pusher 3 is connected between one end of the first side plate 21 and one end of the second side plate 22. The connecting member 23 is connected between the first end of the first side plate 21 and the first end of the second side plate 22 in the third direction. The connection between the first side plate 21 and the second side plate 22 can be achieved through the connecting member 23. The plurality of connecting members 23 are arranged at intervals along the length direction of the driving connector 2. The first direction, the second direction, and the third direction are perpendicular to each other.

[0044] When cooperating with the guide member 202 of the material box, the guide member 202 is located between the second end of the first side plate 21 and the second end of the second side plate 22. The first side plate 21 and the second side plate 22 ensure that during the movement of the driving connecting member 2, the guide member 202 always remains between the first side plate 21 and the second side plate 22. The driving connecting member 2 can only move along the extension direction of the guide member 202, and will not deviate or shake in other directions, thereby preventing the driving connecting member 2 from running off the preset track.

[0045] The second direction is the horizontal direction, the first direction is the longitudinal direction, and the third direction is the vertical direction. The multiple material plates on the material box 200 are arranged at intervals along the vertical direction.

[0046] After the driving connector 2 enters the material box 200, the driving connector 2 is suspended above the guide member 202, and the connector 23 is connected between the upper end of the first side plate 21 and the upper end of the second side plate 22. The lower end of the first side plate 21 and the lower end of the second side plate 22 are stuck on the opposite sides of the guide member 202, thereby forming a guide for the driving connector 2.

[0047] In an alternative embodiment, the guide member 202 includes a first guide plate 2012 and a second guide plate 2013. The first guide plate 2012 and the second guide plate 2013 are arranged relative to each other along the second direction. The second end of the first side plate 21 is configured to slidably engage with the first guide plate 2012 of the guide member 202, and the second end of the second side plate 22 is configured to slidably engage with the second guide plate 2013 of the guide member 202. The first guide plate 2012 guides the first side plate 21, and the second guide plate 2013 guides the second side plate 22, so that the driving connector 2 can only move along the extension direction of the guide member 202 and does not deviate or wobble in other directions.

[0048] Among them, the second end of the first side plate 21 is a U-shaped structure, and the second end of the second side plate 22 is a U-shaped structure, so that when the driving connecting member 2 moves, the first guide plate 2012 and the second guide plate 2013 can be inserted into the U-shaped structure, thereby realizing the sliding fit between the driving connecting member 2 and the guide member 202.

[0049] In one embodiment, if Figure 2 、 Figure 3 As shown, the drive connector 2 is a chain, which includes a plurality of first chain plates 211 and a plurality of second chain plates 221. The plurality of first chain plates 211 are sequentially connected along the length of the drive connector 2 to form a first side plate 21, and the plurality of second chain plates 221 are sequentially connected along the length of the drive connector 2 to form a second side plate 22. The plurality of first chain plates 211 and the plurality of second chain plates 221 provide the chain with a certain degree of flexibility, allowing the chain to adapt to a certain degree of bending and deformation, facilitating chain winding and unwinding, and reducing the volume of the pushing mechanism 100.

[0050] The accommodation space enclosed by the first chain plate 211, the connector 23, and the second chain plate 221 is used to insert the guide member 202. The dimension of the connector 23 in the third direction is smaller than that of the first chain plate 211, and the dimension of the connector 23 in the third direction is smaller than that of the second chain plate 221. That is, in the vertical direction, the bottom of the first chain plate 211 is lower than the bottom of the connector 23, and the bottom of the second chain plate 221 is lower than the bottom of the connector 23. This ensures that the accommodation space between the lower end of the first chain plate 211 and the lower end of the second chain plate 221 is not occupied by the connector 23. After the driving connector 2 is suspended on the guide member 202, the guide member 202 enters the accommodation space between the first chain plate 211 and the second chain plate 221, and can contact the inner side surfaces of the first chain plate 211 and the inner side surfaces of the second chain plate 221, thereby ensuring that the chain moves along the predetermined path.

[0051] In one embodiment, if Figure 1 、 Figure 2 As shown, the first link plate 211 includes a first inner link plate 2111 and a first outer link plate 2112. The first inner link plates 2111 of multiple first link plates 211 and the first outer link plates 2112 of multiple first link plates 211 are alternately hinged. In each first link plate 211, the first end of the first inner link plate 2111 is connected to the first end of the first outer link plate 2112, the second end of the first inner link plate 2111 is connected to the first outer link plate 2112 of the previous first link plate 211, and the second end of the first outer link plate 2112 is connected to the first inner link plate 2111 of the next first link plate 211, so that the connection between the first inner link plate 2111 and the first outer link plate 2112 is tighter and more reliable.

[0052] The second link plates 221 include second inner link plates 2211 and second outer link plates 2212 . The second inner link plates 2211 of the second link plates 221 and the second outer link plates 2212 of the second link plates 221 are hinged alternately. The connecting member 23 is provided between the first inner link plate 2111 and the second inner link plate 2211 .

[0053] In each second link plate 221, the first end of the second inner link plate 2211 is connected to the first end of the second outer link plate 2212, the second end of the second inner link plate 2211 is connected to the second outer link plate 2212 of the previous second link plate 221, and the second end of the second outer link plate 2212 is connected to the second inner link plate 2211 of the next second link plate 221, so that the connection between the second inner link plate 2211 and the second outer link plate 2212 is tighter and more reliable.

[0054] In one embodiment, if Figure 2As shown, the connecting member 23 includes a pin 231 and a chain spacer 232. The chain spacer 232 is sleeved on the outside of the pin 231. One end of the pin 231 is connected to the first inner link plate 2111 and the first outer link plate 2112, and the other end of the pin 231 is connected to the second inner link plate 2211 and the second outer link plate 2212, so that the first inner link plate 2111 and the first outer link plate 2112 can rotate relative to each other, and the second inner link plate 2211 and the second outer link plate 2212 can rotate relative to each other.

[0055] In one embodiment, if Figure 2 As shown, along the length direction of the drive connector 2, the first inner link plates 2111 are provided with a first protrusion and a first recess at both ends. Between two adjacent first inner link plates 2111, the first protrusion of one first inner link plate 2111 fits within the first recess of the other first inner link plate 2111. The first outer link plates 2112 are provided with a second protrusion and a second recess at both ends. Between two adjacent first outer link plates 2112, the second protrusion of one first outer link plate 2112 fits within the second recess of the other first outer link plate 2112.

[0056] The second inner link plates 2211 are provided with a third protrusion and a third recess at each end. Between two adjacent second inner link plates 2211, the third protrusion of one second inner link plate 2211 engages with the third recess of the other second inner link plate 2211. The second outer link plates 2212 are provided with a fourth protrusion and a fourth recess at each end. Between two adjacent second outer link plates 2212, the fourth protrusion of one second outer link plate 2212 engages with the fourth recess of the other second outer link plate 2212. The coordination of the protrusion and recess ensures that the chain can only curl upward. Before the chain transitions to the material box 200, the pusher 3 at the end of the chain will not be affected by the downward bending of the chain, which would hinder its entry into the material box 200.

[0057] In one embodiment, if Figure 1 、 Figure 2 As shown, the driving member 1 includes a motor 11, a connecting shaft 12, and a sprocket 13. One end of the connecting shaft 12 is connected to the output end of the motor 11, and the other end of the connecting shaft 12 is mounted on the sprocket 13, which meshes with the chain. The motor 11 can drive the connecting shaft 12 to rotate, which in turn drives the sprocket 13 to rotate. The meshing action between the sprocket 13 and the chain can drive the chain to move.

[0058] In one embodiment, if Figure 2As shown, the pushing mechanism 100 also includes a accommodating box 4, the driving member 1 is installed in the accommodating box 4, the two ends of the driving connecting member 2 in the length direction are respectively a connecting end and a receiving end, the receiving end is accommodated in the accommodating box 4, and the connecting end is connected to the pushing member 3. The driving member 1 can drive the driving connecting member 2 to be released from the accommodating box 4 or recovered into the accommodating box 4. When the driving member 1 drives the driving connecting member 2 to be released from the accommodating box 4, it can drive the pushing member 3 to enter the material box 200 and abut against the material sheet. The driving connecting member 2 and the guide member 202 on the material box 200 are slidably matched. As the driving connecting member 2 is gradually released, the length of the part of the driving connecting member 2 outside the accommodating box 4 gradually increases, so that the pushing member 3 can push the material sheet out of the material box 200, and the material sheet enters the next process.

[0059] By setting up a accommodating box 4, the driving connecting member 2 can be retracted and extended under the drive of the driving member 1, so that when the retraction and extension action is performed, the connecting end drives the pushing member 3 to move and form a reciprocating movement, and the driving connecting member 2 can be accommodated in the accommodating box 4, which can reduce the space occupied by the driving connecting member 2 and reduce the overall volume of the pushing mechanism 100.

[0060] Preferably, the sprocket 13 is located in the accommodating box 4 , and the sprocket 13 is arranged close to the chain outlet of the accommodating box 4 , the connecting end can pass over the sprocket 13 and extend from the chain outlet, and the receiving end remains in the accommodating box 4 .

[0061] In one embodiment, if Figure 1 As shown, the pushing mechanism 100 also includes a sensor 5, which is installed on the containing box 4. The sensor 5 is used to detect the position of the pushing member 3 when the driving member 1 drives the driving connecting member 2 to be recovered to the containing box 4. When the driving connecting member 2 is gradually recovered into the containing box 4, the position of the pushing member 3 is detected by the sensor 5. When the driving connecting member 2 is recovered and the pushing member 3 is close to the containing box 4, the sensor 5 receives a signal and the driving member 1 stops running, so as to avoid the driving member 1 from continuing to run and the pushing member 3 causing damage to the containing box 4.

[0062] In one embodiment, if Figure 3 As shown, a first notch 212 is provided at one end of the first side plate 21 near the pusher 3, and a second notch 222 is provided at one end of the second side plate 22 near the pusher 3. During the movement of the drive connector 2, the sensor 5 can continuously sense the drive connector 2 and monitor the position of the drive connector 2 in real time. Due to the presence of the first notch 212 and the second notch 222, when the sensor 5 does not detect the drive connector 2 at the first notch 212 and the second notch 222, it can be determined that the pusher 3 has reached the designated position and the drive connector 2 has been completely retracted into the accommodating box 4, thereby avoiding the situation where the drive connector 2 is not fully retracted or is over-retracted.

[0063] In one embodiment, if Figure 4As shown, the pushing mechanism 100 also includes a lifting component 6 and a mounting seat 7. The accommodating box 4 is installed on the mounting seat 7. The lifting component 6 is used to drive the mounting seat 7 to move up and down, so as to drive the accommodating box 4 to move up and down. According to the size and model of the material box 200, the docking height of the material box 200 is determined. The mounting seat 7 is driven up and down by the lifting component 6, so that after the mounting seat 7 reaches the docking height, the material box 200 is lifted and lowered, so that the pushing mechanism 100 can dock with each material plate of the material box 200 to realize the pushing of each material plate.

[0064] In one embodiment, the lifting assembly 6 includes a lifting motor 61, a lifting screw 62, a sliding connecting plate 63 and a guide column 64. The output end of the lifting motor 61 is connected to the lifting screw 62, and the sliding connecting plate 63 is threadedly connected to the lifting screw 62. When the lifting motor 61 drives the lifting screw 62 to rotate, it can drive the sliding connecting plate 63 to move up and down. The guide column 64 is slidably connected to the sliding connecting plate 63 and can guide the sliding connecting plate 63 when it moves up and down.

[0065] In one embodiment, if Figure 4 As shown, the mounting base 7 includes a mounting bracket 71 and an adjustment plate 72. The mounting bracket 71 is connected to the sliding connecting plate 63. One end of the adjustment plate 72 is connected to the mounting bracket 71, and the other end of the adjustment plate 72 is connected to the accommodating box 4. The mounting height of the adjustment plate 72 on the mounting bracket 71 is adjustable, so that the position of the drive connector 2 can be accurately adjusted, so that the drive connector 2 can be better docked with the material box 200, which facilitates the sliding cooperation between the drive connector 2 and the guide member 202.

[0066] Specifically, a plurality of strip holes are provided on the adjustment plate 72 , and the strip holes extend in the vertical direction. The installation position of the accommodating box 4 on the mounting seat 7 can be fine-tuned through the strip holes, thereby adjusting the position of the pusher 3 .

The material box 200 and the pushing mechanism 100 are installed on the automatic guided transport vehicle. The automatic guided transport vehicle moves flexibly, thereby driving the material box 200 to move and realize the distribution of the material plate.

[0068] The material box 200 is provided with a plurality of support frames 201 spaced apart in the vertical direction. The support frames 201 are used to carry the material sheets. The guide members 202 are provided on the support frames 201 . The pushing member 3 can push the material sheets to move along the guide members 202 under the drive of the driving member 1 to send the material sheets out of the material box 200 .

[0069] The support frame 201 includes a frame body 2011, a first guide plate 2012, and a second guide plate 2013. The first guide plate 2012 and the second guide plate 2013 are mounted on the frame body 2011 and are positioned relative to each other in a second direction. A guide groove is formed between the first guide plate 2012 and the second guide plate 2013. During movement of the PCB, pins on the PCB move along the guide groove. A guide member 202 is formed between the side of the first guide plate 2012 closest to the second guide plate 2013 and the side of the second guide plate 2013 closest to the first guide plate 2012.
