[0047] With reference to Figures 1 to 4, an embodiment of the present application discloses a sheet material receiving and releasing device, which includes a material box 1, a power mechanism 2 and a supporting mechanism 3. The material box 1 is used to store sheet materials (sheet materials can be, for example, PCB boards), and the supporting mechanism 3 is used to hold the material box 1. During loading, the material box 1 placed on the supporting mechanism 3 is transported to the material receiving and releasing position of the processing platform by the power mechanism 2, and the transmission mechanism in the material box 1 is driven by the power mechanism 2 to move, so that the transmission mechanism drives the sheet materials stored in the material box 1 to move, so that the sheet materials stored in the material box 1 are transported to the processing platform, thereby realizing the loading of the sheet materials.

[0048] As shown in FIG5 , the material box 1 includes a frame 11, a transmission mechanism 12, and a support assembly 13. There are multiple support assemblies 13, each of which is respectively arranged on the frame 11. The multiple support assemblies 13 are respectively distributed along the height extension direction of the frame 11 (the Z direction in FIG5 ), so that the frame 11 is divided into multiple layers of storage bins, and each support assembly 13 is used to support each sheet material. There are multiple transmission mechanisms 12, each of which is respectively arranged on each layer of the storage bin, for receiving the driving force output by the power mechanism 2 to drive the sheet material to move within the frame 11, thereby transporting the sheet material stored in each layer of the storage bin to the processing platform, or transporting the sheet material processed on the processing platform to the material box 1.

[0049] As shown in Figures 6 and 7, each transmission mechanism 12 includes a lever power receiving member 121 and a conveying mechanism 12a. Each conveying mechanism 12a and each lever power receiving member 121 are spaced apart in the vertical direction, and each lever power receiving member 121 is respectively connected to each conveying mechanism 12a. The lever power receiving member 121 is used to receive the power output by the power mechanism 2 to drive the conveying mechanism 12a to move, thereby driving the sheet material within the frame 11 through the conveying mechanism 12a. Furthermore, the conveying mechanism 12a includes a rotating shaft 122, a driving pulley 123, a driven pulley 124, a belt 125, a driven pulley mounting seat 126, and a lever power receiving member 121.

The driven wheel mounting seat 126 is provided on the frame 11 and is located on the other side of the frame 11. The driving wheel 123 is sleeved on the rotating shaft 122. The driven wheel 124 is rotatably provided on the driven wheel mounting seat 126. The belt 125 is wound around the driving wheel 123 and the driven wheel 124. The shift lever power receiving member 121 is connected to one end of the rotating shaft 122 and is used to cooperate and engage with the shift block in the power mechanism 2 to receive the driving force output by the power mechanism 2.

[0050] Furthermore, the rotation axis 122 includes a plurality of connecting shafts 122a and a plurality of first couplings 122b. The connecting shafts 122a are connected by the first couplings 122b to form the rotation axis 122. The deflector lever power receiving member 121 includes a rotation base 121a and a deflector lever shaft 121b. A plurality of deflector lever shafts 121b are provided, and the plurality of deflector lever shafts 121b are spaced apart from each other on the rotation base 121a. In this embodiment, each deflector lever power receiving member 121 is provided with two deflector lever shafts 121b, which are disposed on opposite sides of the rotation base 121a.

[0051] Each support assembly 13 includes a plurality of support shafts 131 and a plurality of support members 132. The support shafts 131 are respectively connected to the frame 11 and are spaced apart in a direction perpendicular to the lengthwise extension direction of the rotation shaft 122. The lengthwise extension direction of each support shaft 131 is the same as the lengthwise extension direction of the rotation shaft 122. Each support member 132 is connected to each support shaft 131, and the lengthwise extension direction of each support member 132 intersects the lengthwise extension direction of the support shaft 131. In this embodiment, the lengthwise extension direction of each support member 132 is perpendicular to the lengthwise extension direction of each support shaft 131.

[0052] In this embodiment, each supporting assembly 13 is provided with two supporting shafts 131 , and the two supporting shafts 131 are respectively located on two sides of the frame 11 , and supporting members 132 are respectively provided on two sides of each belt 125 .

[0053] Continuing with Figure 5 , the material bin 1 further includes a stopper 15, a positioning block 16, and a guide member 14. The positioning block 16 is connected to the frame 11 and has a positioning hole for cooperating with a positioning pin in the power mechanism 2. The stopper 15 is connected to the frame 11 and is located on the same side of the frame 11 as the rotation axis 122. The length of the stopper 15 extends along the height of the frame 11 and is used to limit the position of the sheet materials stored in the material bin 1. Multiple guide members 14 are provided, with at least one guide member 14 provided on each storage bin layer. Each guide member 14 is also provided with a guide slot 141, which is used to cooperate with the pins of the sheet materials to guide the sheet materials during movement.

[0054] When storing the sheet materials, each sheet material is placed in each storage bin of the material box 1, and the sheet materials in each storage bin are located on the upper surface of each support member 132 and the belt 125, and the pins of the sheet materials are placed in the guide groove 141 of the guide member 14.

[0055] 8 and 9 , the power mechanism 2 includes a main body 21, a lifting assembly 22, a bin bracket 23, and a drive assembly 24. The bin bracket 23 is movably connected to the main body 21 and is used to carry the bin 1. The drive assembly 24 is disposed on one side of the main body 21 and is used to cooperate with the transmission mechanism 12 of the bin 1 to drive the transmission mechanism 12 to move. The lifting assembly 22 is disposed on the main body 21 and is connected to the bin bracket 23. It is used to drive the bin bracket 23 to move up and down, thereby driving the bin 1 to move up and down, so that the transmission mechanisms 12 provided on each storage bin layer of the bin 1 can cooperate with the drive assembly 24.

[0056] As shown in Figure 10, the drive assembly 24 includes a support base 241, a push rod motor fixing base 249, a paddle motor fixing plate 24a, a push rod motor 242, a paddle motor 243, a transition floating block 244, a connecting block 245, a connecting plate 246, a sliding guide rail fixing plate 247, a sliding guide rail 248, a bearing base 24b, a second coupling 24c, a reinforcing rib 24j, and a toggle block 240. The support base 241 is connected to the main body 21, the sliding guide rail fixing plate 247 is connected to the support base 241, and the sliding guide rail 248 is disposed on the sliding guide rail fixing plate 247. The push rod motor fixing base 249 is connected to the support base 241, the push rod motor 242 is mounted on the push rod motor fixing base 249, and the push rod motor 242 is connected to the transition floating block 244. The transition floating block 244 is clearance-fitted with the connecting block 245. The connecting plate 246 is connected to the connecting block 245, and the connecting plate 246 is also slidably connected to the sliding guide rail 248. The bearing seat 24b is connected to the connecting plate 246, and the toggle block 240 is movably mounted on the bearing seat 24b. The toggle block 240 can respectively dock with each toggle lever power receiving member 121 to form a transmission connection. The toggle block 240 toggle the toggle lever power receiving member 121 to move, causing the conveyor mechanism 12a to drive the sheet material to move. The paddle motor fixing plate 24a is connected to the connecting plate 246 via the reinforcing rib 24j. The paddle motor 243 is mounted on the paddle motor fixing plate 24a and is connected to the toggle block 240 via the second coupling 24c. The paddle motor 243 drives the toggle block 240 to rotate, and the push rod motor 242 drives the toggle block 240 to move in the first direction, causing the toggle block 240 to move closer to or away from the toggle lever power receiving member 121. The first direction refers to the axial direction of the push rod motor, which is the X direction in FIG10 .

[0057] In this embodiment, the push rod motor 242 is connected to a transition floating block 244, which is loosely fitted with the connecting block 245. This prevents radial forces from being applied to the output shaft of the push rod motor 242, thereby preventing damage to the push rod motor 242 due to overload. If the push rod motor is directly connected to the connecting block without a transition floating block, the output shaft of the push rod motor directly connected to the connecting block will also deflect if the connecting block deflects during movement.

[0058] Furthermore, the toggle block 240 includes a fixed portion 240a and an engaging portion 240b. The fixed portion 240a is mounted on the bearing seat 24b, and the engaging portion 240b is connected to the fixed portion 240a. The engaging portion 240b has a plate-like structure and has a first surface, a second surface, a first side surface, a second side surface, and an end portion. The first surface and the second surface are disposed opposite each other, and the first side surface and the second side surface are disposed opposite each other. The end portion is connected to the first surface, the second surface, the first side surface, and the second side surface, respectively, and the cross-section of the end portion is tapered. In this embodiment, by providing the end portion with a tapered shape, the engaging portion 240b can more smoothly extend between the two toggle lever shafts 121b.

[0059] To detect the position of the toggle block 240 and the lever power receiving member 121, the drive assembly 24 also includes a toggle block position sensor 24d, a first barrier 24e, and a lever photoelectric sensor 24f. The toggle block position sensor 24d is connected to the connecting plate 246, and the first barrier 24e is connected to the fixed portion 240a. The first barrier 24e and the toggle block position sensor 24d cooperate to detect the position of the toggle block 240. The lever photoelectric sensor 24f is connected to the connecting plate 246 and is used to detect the position of the lever power receiving member 121. In this embodiment, when the position of the first baffle 24e corresponds to the position of the toggle block position sensor 24d, the toggle block position sensor 24d generates a trigger signal, confirming that the toggle block 240 is in the third position at this time (the first surface and the second surface of the engaging portion are basically parallel to the horizontal plane); when the toggle lever photoelectric sensor 24f generates a trigger signal, it is confirmed that the toggle lever power receiving component 121 is in the first position at this time (the line connecting the two toggle lever shafts 121b intersects with the horizontal plane), otherwise it is confirmed that the toggle lever power receiving component 121 is in the second position (the line connecting the two toggle lever shafts 121b is basically parallel to the horizontal plane).

[0060] In some embodiments, the toggle block position sensor 24 d may be connected to the fixing portion 240 a , and the first blocking piece 24 e may be connected to the connecting plate 246 .

[0061] To detect the movement distance of the toggle block 240 in the first direction, the drive assembly further includes a photoelectric adjustment block 24i, a photoelectric sensor 24g, and a second baffle 24h. The photoelectric adjustment block 24i is connected to the slide rail fixing plate 247, the photoelectric sensor 24g is movably connected to the photoelectric adjustment block 24i, and the second baffle 24h is connected to the connecting plate 246. The toggle block position sensor 24d, the toggle lever photoelectric sensor 24f, and the photoelectric sensor 24g can be photoelectric sensors (photoelectric switches). The detection principle of the photoelectric sensor is to use the obstruction or reflection of the light beam by the detected object, and the synchronization circuit selects the circuit to detect the presence of the object.

[0062] In practice, the position of photoelectric sensor 24g on photoelectric adjustment block 24i is adjusted based on the desired movement distance of toggle block 240. Specifically, the initial distance between photoelectric sensor 24g and second barrier 24h is adjusted. When push motor 242 drives toggle block 240 in a first direction, connecting plate 246 drives second barrier 24h in the first direction. When the position of second barrier 24h corresponds to the position of photoelectric sensor 24g, photoelectric sensor 24g generates a trigger signal, confirming that toggle block 240 has moved the preset distance.

[0063] In some examples, the photoelectric sensor 24g may be connected to the connecting plate 246, and the second blocking piece 24h may be movably connected to the photoelectric adjustment block 24i.

[0064] Furthermore, the lifting assembly 22 includes a driving member and a transmission member. The transmission member is movably arranged on the main body 21. The driving member is arranged on the main body 21 and connected to the transmission member. The material box bracket 23 is connected to the transmission member so that the transmission member is driven to move by the driving member, thereby driving the material box bracket 23 to perform lifting and lowering movements.

[0065] Continuing with reference to Figure 8, in order to detect the lifting height of the material box bracket 23, the power mechanism 2 also includes a lifting sensor 25a and a lifting sensor plate 25b. The lifting sensor 25a is arranged on the main body 21, and the lifting sensor plate 25b is arranged on the material box bracket 23. When the material box bracket 23 moves to make the position of the lifting sensor plate 25b correspond to the position of the lifting sensor 25a, the lifting sensor 25a generates a trigger signal, confirming that the material box bracket 23 has risen to the predetermined position.

[0066] In some embodiments, the driving member may be a lifting motor 221, and the transmission member may be a screw rod, so that the lifting motor 221 drives the screw rod to rotate, thereby driving the material box bracket 23 threadedly connected to the screw rod to perform lifting movements.

[0067] In other embodiments, the drive element is a motor, and the transmission element can also be a sprocket and chain. The motor is connected to the sprocket via a reducer, the sprocket engages the chain, and the chain is connected to the material box bracket 23. When the motor and reducer drive the sprocket to rotate, the chain moves, thereby driving the material box bracket 23 connected to the chain. Of course, the drive assembly can also be a linear module, cylinder, or other drive assembly, and the specific selection can be based on actual conditions.

[0068] Continuing with Figure 9, the power mechanism 2 also includes a positioning pin 25, a bumper plate 26, a reinforcement block 27, a material collection and release guide device 28, and an electrical control box 29. The positioning pin 25 is mounted on the bin bracket 23 and is used to engage with the positioning hole in the positioning block 16 to position the bin 1. The bumper plate 26 is connected to the bin bracket 23. When the bumper plate 26 strikes an object, the power mechanism 2 stops and an alarm is sounded. The material collection and release guide device 28 is connected to the main body 21, and the material collection and release guide device 28 and the drive assembly 24 are respectively located on either side of the main body 21. The material collection and release guide device 28 can guide the material sheets being fed into or out of the bin 1. The electrical control box 29 is mounted on the main body 21 and is connected to the lifting assembly 22, the drive assembly 24, and the bumper plate 26 to control the operation of the lifting assembly 22 and the drive assembly 24. There are two reinforcing blocks 27, which are respectively arranged on the material box bracket 23 and located on both sides of the positioning pin 25. When the material box 1 is assembled on the material box bracket 23, the positioning block 16 is sleeved on the positioning pin 25, and the material box 1 is limited by the two reinforcing blocks 27 to prevent the material box 1 from swinging left and right.

[0069] 4 , the supporting mechanism 3 includes a support frame 31, a plurality of support bearings 33, and a plurality of limit blocks 32. The plurality of support bearings 33 are respectively provided on the upper surface of the support frame 31 for supporting the material box 1. The plurality of limit blocks 32 are respectively provided on the upper surface of the support frame 31 for limiting the position of the material box 1.

[0070] In actual application scenarios, when loading materials, the power mechanism 2 runs to the carrying mechanism 3 and places the material box bracket 23 inside the carrying mechanism 3, and then drives the material box bracket 23 to rise to a certain height through the lifting component 22, so that the material box bracket 23 lifts the material box 1, and then the power mechanism 2 drives the material box 1 to run to the material storage and release position of the processing platform. At this time, the lifting component 22 drives the material box bracket 23 to move up and down, so as to drive the material box 1 to move up and down, so that the storage bin to be discharged in the material box 1 corresponds to the driving component 24, that is, the toggle block 240 corresponds to the toggle lever power receiving component 121 in height; then the toggle lever photoelectric sensor 24f detects the position of the toggle lever power receiving component 121, and when the toggle lever photoelectric sensor 24f When no trigger signal is generated, it is confirmed that the lever power receiving member 121 is in the first position. At this time, the push rod motor 242 directly drives the toggle block 240 to move in the first direction toward the toggle lever power receiving member 121, so that the engaging portion 240b of the toggle block 240 extends into between the two toggle lever shafts 121b of the toggle lever power receiving member 121. When the photoelectric sensor 24g generates a trigger signal, the push rod motor 242 stops driving the toggle block 240 to move; when the toggle lever photoelectric sensor 24f generates a trigger signal, the push rod motor 242 stops driving the toggle block 240 to move. When the trigger signal is received by the photoelectric sensor 24g, it is confirmed that the lever power receiving member 121 is in the second position. At this time, the paddle motor 243 first drives the toggle block to rotate 90 degrees, and then the push rod motor 242 drives the toggle block 240 to move in the first direction toward the toggle power receiving member 121, so that the engaging portion 240b of the toggle block 240 extends between the two lever shafts 121b of the toggle power receiving member 121. When the photoelectric sensor 24g generates a trigger signal, the push rod motor 242 stops driving the toggle block 240 to move. After the toggle block 240 stops moving in the first direction, the paddle motor 243 drives the toggle block 240 to rotate, thereby engaging the toggle block 240 with the lever power receiving member 121 and driving the lever power receiving member 121 to rotate, thereby driving the belt 125 and the sheet material placed on the upper surface of the belt 125 to move, thereby achieving sheet material loading. After the materials are loaded into the storage bin on the corresponding level, the push rod motor 242 drives the toggle block 240 to move in the first direction away from the toggle rod power receiving member 121, so that the toggle block 240 is separated from the toggle rod power receiving member 121. At this time, if the toggle rod photoelectric sensor 24f does not generate a trigger signal, it is determined that the toggle block 240 is not in the third position, and the paddle motor 243 is required to drive the toggle block 240 to rotate until the toggle rod photoelectric sensor 24f generates a trigger signal, that is, the toggle block 240 is in the third position. The unloading process is basically the same as the loading process, except that during unloading, the paddle motor 243 drives the belt 125 to rotate in the opposite direction to that during loading.
