[0072] Please see Figures 5 to 10 , Figure 10 The diagram shows a schematic of the structure of a circuit board loading and unloading system according to an embodiment of the present application. The circuit board loading and unloading system 1 provided in an embodiment of the present application includes a frame structure 10, at least one frame 20, a conveying device 30 and a support frame 40. The frame structure 10 includes a first frame 110 and a second frame 120 arranged along a first direction; a rack 20 is connected to the first frame 110, and the rack 20 is provided with a plurality of transmission stations (not shown in the figure) arranged along a second direction. The transmission stations are used to transmit circuit boards. The rack 20 includes a fixed part 210 and a cantilever part 220 arranged along a third direction.

The conveying components 310 are arranged on the rack 20 and are configured to transmit circuit boards along the third direction; one end of the support frame 40 is connected to the first frame 110, and the other end contacts the cantilever part 220 of the rack 20 to support the cantilever part 220.

[0073] In this embodiment of the circuit board loading and unloading system 1, the fixing part 210 of the frame 20 is located in the space between the first frame 110 and the second frame 120. The cantilever part 220 of the frame 20 is located on one side of the first frame 110 and the second frame 120 along a third direction. The conveying assembly 310 is disposed on the frame 20 and conveys circuit boards along a third direction. By setting the cantilever part 220, the size of the frame 20 in the third direction can be increased, thereby increasing the size of the conveying assembly 310 in the third direction, which facilitates the conveying assembly 310 to convey larger circuit boards along the third direction. When the conveying assembly 310 conveys the circuit board, the support frame 40 supports the cantilever part 220 of the frame 20 to prevent the cantilever part 220 of the frame 20 from shaking, improve the stability of the conveying assembly 310, and avoid loosening of the connections of various components in the circuit board loading and unloading system 1 due to the shaking of the cantilever part 220.

[0074] In summary, the circuit board loading and unloading system 1 in this embodiment can transport circuit boards of larger size. One end of the support frame 40 is connected to the first frame 110, and the other end is in contact with the cantilever portion 220 of the frame 20. This can support the cantilever portion 220 of the frame 20, prevent the cantilever portion 220 of the frame 20 from shaking, and improve the stability of the transport component 310.

[0075] Please see Figure 5 and Figure 6 In some embodiments, the conveying assembly 310 includes two conveying members 311 arranged along a second direction. Each conveying member 311 includes a mounting frame 311-1, a conveyor belt 311-2, and two conveying wheels 311-3.

[0076] In this embodiment, when the conveying component 310 transmits the circuit board, it places the circuit board on the conveyor belt 311-2 of the two conveying components 311, and then drives the conveyor wheel 311-3 in each conveying component 311 to rotate. The conveyor wheel 311-3 drives the conveyor belt 311-2, so that the conveyor belt 311-2 drives the circuit board to move in a third direction.

[0078] In this embodiment, the first driving member 320 drives the driving rod 312 to rotate around its own axis. The driving rod 312 drives the two conveying wheels 311-3 coaxially arranged with it to rotate, thereby causing the conveyor belts 311-2 in the two conveying members 311 to move at the same speed at the same time.

[0079] In some embodiments, the conveying assembly 310 includes a coupling 313. In a plurality of conveying assemblies 310 arranged along the second direction, the drive rod 312 in each conveying assembly 310 is connected to the drive rod 312 in the adjacent conveying assembly 310 through the coupling 313 in the conveying assembly 310.

A portion of the multiple conveying components 310 are disposed on one of the racks 20 and correspond one-to-one with the multiple transmission stations on the corresponding rack 20. Another portion of the multiple conveying components 310 are disposed on the other rack 20 and correspond one-to-one with the multiple transmission stations on the corresponding rack 20.

[0081] In this embodiment, by setting two racks 20, the number of conveying components 310 can be increased by setting multiple conveying components 310 on each rack 20, thereby improving the transmission efficiency of the circuit board loading and unloading system 1.

The second driving member 331-1 is configured to drive the top plate 331-2 to move along a first direction.

[0084] In this embodiment, the circuit board to be transferred is placed on the two top plates 331-2 in the temporary storage component 330. After the circuit board on the two conveyor belts 311-2 in the temporary storage component 310 is transferred, the second driving member 331-1 of each lifting member 331 in the temporary storage component 330 corresponding to the conveying component 310 will drive the top plate 331-2 in the lifting member 331 to approach the first frame 110 along the first direction, so that the circuit board to be transferred on the two top plates 331-2 comes into contact with the two conveyor belts 311-2 in the corresponding conveying component 310, which facilitates the subsequent transfer of the circuit board by the conveyor belts 311-2.

[0093] In this embodiment, the fourth driving member 620 drives the driving wheel to rotate, the driving wheel drives the transmission belt 630 to move, the transmission belt 630 drives the driven wheel to rotate, the driven wheel drives the screw 612 to rotate around its own axis, and the rotating screw 612 drives the lifting member 613 to move relative to the first frame 110 in the first direction, so that the lifting member 613 can drive the frame 20 to move relative to the first frame 110 in the first direction.

[0094] Please see Figure 10 andFigure 11 In some embodiments, the circuit board loading and unloading system 1 includes a housing 70, which includes a first baffle 710, a second baffle 720, and a third baffle 730. The first baffle 710 is located on the side of the second frame 120 away from the first frame 110 along a first direction, the third baffle 730 is located on the side of the connecting frame 130 away from the cantilever portion 220 of the frame 20 along a third direction, and the second baffle 720 is located on the side of the connecting frame 130 along a second direction.

[0095] In some embodiments, the circuit board loading and unloading system 1 includes a display 80, which is disposed on a first baffle 710. The first drive unit 320, the second drive unit 331-1, the third drive unit 342 and the fourth drive unit 620 are all communicatively connected to the control unit (not shown) in the display 80.

[0096] Please see Figures 1 to 4 In some embodiments, the frame structure 10 includes at least one connecting frame 130. The second frame 120 includes two longitudinal beams 121 arranged along a second direction, two transverse beams 122 located between the two longitudinal beams 121, a reinforcing beam 123, and a plurality of connecting beams 124. The two transverse beams 122 are arranged along a third direction, and their two ends are respectively connected to the two longitudinal beams 121. The first direction is parallel to the gravity direction of the transverse beams 122. The reinforcing beam 123 is located between the two transverse beams 122, and its two ends are respectively connected to the two longitudinal beams 121. A connecting beam 124 is provided in the gap between the two transverse beams 122 and the reinforcing beam 123. The two ends of the connecting beam 124 are respectively connected to the reinforcing beam 123 and the transverse beam 122. One end of the connecting frame 130 is connected to the first frame 110, and the other end is connected to the longitudinal beam 121.

[0097] In this embodiment, the frame structure 10 has a first frame 110 and a second frame 120 arranged along a first direction. One end of the connecting frame 130 is connected to the first frame 110, and the other end is connected to the longitudinal beam 121 in the second frame 120. The space between the first frame 110 and the second frame 120 is used to accommodate objects. The two longitudinal beams 121 in the second frame 120 are arranged along a second direction, and two crossbeams 122 are located between the two longitudinal beams 121. The two ends of the crossbeams 122 are connected to the two longitudinal beams 121 respectively. When the distance between the two longitudinal beams 121 is large, the size of the crossbeams 122 in the second direction increases accordingly. As the size of the crossbeams 122 increases, the weight of the crossbeams 122 will increase, and the gravity of the crossbeams 122 will also increase accordingly. During this process, the reinforcing beam 123 between the two crossbeams 122 will exert a force on the crossbeam 122 through the connecting beam 124, which will counteract the weight of the crossbeam 122 itself and reduce the risk of the crossbeam 122 sagging in the first direction, so as to further increase the distance between the two longitudinal beams 121 and raise the space between the first frame 110 and the second frame 120 in the second direction.

[0098] In summary, the circuit board loading and unloading system 1 in this embodiment has a reinforcing beam 123 located between two crossbeams 122, and a connecting beam 124 provided in the gap between the two crossbeams 122 and the reinforcing beam 123. The two ends of the connecting beam 124 are connected to the reinforcing beam 123 and the crossbeams 122 respectively, which can reduce the risk of the crossbeams 122 sagging.

[0099] Please see Figure 1 In some embodiments, each crossbeam 122 is connected to a reinforcing beam 123 by a plurality of connecting beams 124 arranged along the second direction.

[0100] In this embodiment, each crossbeam 122 is connected to a reinforcing beam 123 through multiple connecting beams 124. The reinforcing beam 123 between two crossbeams 122 will exert a force on the crossbeam 122 through multiple connecting beams 124 to counteract the weight of the crossbeam 122 itself and reduce the risk of the crossbeam 122 sagging in the first direction.

[0101] Please see Figure 1 In some embodiments, the frame structure 10 includes a plurality of first connectors 140. Each first connector 140 has two first connecting holes 141. A first fastener (not shown) passes through the first connecting hole 141. The first connectors 140 are provided at the connection between the connecting beam 124 and the reinforcing beam 123, and at the connection between the connecting beam 124 and the crossbeam 122. Two first fasteners in the first connectors 140 at the connection between the connecting beam 124 and the reinforcing beam 123 are threadedly connected to the connecting beam 124 and the reinforcing beam 123, respectively. Two first fasteners in the first connectors 140 at the connection between the connecting beam 124 and the crossbeam 122 are threadedly connected to the connecting beam 124 and the crossbeam 122, respectively.

[0102] In this embodiment, by threading two first fasteners in the first connector 140 at the connection between the connecting beam 124 and the reinforcing beam 123 to the connecting beam 124 and the reinforcing beam 123 respectively, the connection between the connecting beam 124 and the reinforcing beam 123 can be strengthened, and the stability of the connection between the connecting beam 124 and the reinforcing beam 123 can be improved. Similarly, by threading two first fasteners in the first connector 140 at the connection between the connecting beam 124 and the crossbeam 122 to the connecting beam 124 and the crossbeam 122 respectively, the connection between the connecting beam 124 and the crossbeam 122 can be strengthened, and the stability of the connection between the connecting beam 124 and the crossbeam 122 can be improved.

[0103] It should be noted that the first connector 140 includes, but is not limited to, a single tripod.

[0104] In some embodiments, the strength of the reinforcing beam 123 is greater than the strength of the crossbeam 122.

[0105] Please see Figure 1 In some embodiments, the frame structure 10 includes a plurality of second connectors 150, each second connector 150 having two second connection holes 151, and a second fastener (not shown) passing through the second connection hole 151; at the connection between the crossbeam 122 and the longitudinal beam 121, a second connector 150 is provided, and two of the second fasteners in the second connector 150 at the connection between the crossbeam 122 and the longitudinal beam 121 are threadedly connected to the crossbeam 122 and the longitudinal beam 121, respectively.

[0106] In this embodiment, the two second fasteners in the second connector 150 at the connection between the crossbeam 122 and the longitudinal beam 121 are threadedly connected to the crossbeam 122 and the longitudinal beam 121 respectively, which can strengthen the connection between the crossbeam 122 and the longitudinal beam 121 and improve the stability of the connection between the crossbeam 122 and the longitudinal beam 121.

[0107] Please see Figure 1 In some embodiments, the reinforcing beam 123 extends along the second direction, and both ends of the reinforcing beam 123 are provided with mounting portions 123-1. The two mounting portions 123-1 are provided in a one-to-one correspondence with the two longitudinal beams 121. The mounting portions 123-1 are provided with mounting holes 123-2, and a third fastener (not shown) passes through the mounting holes 123-2. The third fastener passing through the mounting holes 123-2 in the mounting portions 123-1 is threadedly connected to the longitudinal beam 121 corresponding to the mounting portion 123-1.

[0108] In this embodiment, the third fastener inserted in the mounting hole 123-2 of the mounting part 123-1 is threadedly connected to the longitudinal beam 121 corresponding to the mounting part 123-1, which can strengthen the connection between the reinforcing beam 123 and the longitudinal beam 121 and improve the stability of the connection between the reinforcing beam 123 and the longitudinal beam 121.

[0109] Please see Figures 1 to 4 In some embodiments, the frame structure 10 includes a frame connector 160, which includes a support portion 161 and a connecting portion 162 connected to each other. The support portion 161 is located on the side of the reinforcing beam 123 close to the first frame 110 along the first direction and is connected to the reinforcing beam 123. The connecting portion 162 is located on the side of the connecting frame 130 along the second direction. The connecting portion 162 is provided with a waist-shaped groove 162-1 extending along the first direction. The waist-shaped groove 162-1 passes through the connecting portion 162 along the second direction. A connecting bolt (not shown) passes through the waist-shaped groove 162-1. The nut in the connecting bolt contacts the side of the connecting portion 162 away from the connecting frame 130, and the screw in the connecting bolt is threadedly connected to the connecting frame 130.

[0110] In this embodiment, when adjusting the distance between the first frame 110 and the second frame 120, the operator loosens the connecting bolts and applies a pushing force to the reinforcing beam 123, pushing the reinforcing beam 123 to move along the first direction. During this process, the reinforcing beam 123 drives the support part 161 to move synchronously. Under the action of the support part 161, the connecting part 162 moves closer to the first frame 110 along the first direction, and the position of the connecting bolts in the waist-shaped groove 162-1 changes. After the distance between the first frame 110 and the second frame 120 reaches the target value, the operator stops pushing the reinforcing beam 123, tightens the connecting bolts, and locks the relative position of the second frame 120 and the connecting frame 130 to prevent the second frame 120 from moving closer to the first frame 110 along the first direction under its own gravity.

[0111] Please see Figures 1 to 4 In some embodiments, the connecting frame 130 includes two uprights 131, a connecting column 132, and a supporting column 133. The uprights 131 extend along a first direction and are located on the side of the first frame 110 near the second frame 120 and connected to the first frame 110. The two uprights 131 are arranged at intervals along a third direction. The connecting column 132 is located between the two uprights 131, and both ends of the connecting column 132 are connected to the two uprights 131 respectively. The supporting column 133 extends along the first direction and is located on the side of the connecting column 132 away from the first frame 110 along the first direction. The connecting part 162 in the frame connector 160 is located on the side of the supporting column 133 along a second direction. The thread in the connecting bolt passes through the waist-shaped groove 162-1 on the connecting part 162 and is threadedly connected to the supporting column 133.

[0112] In this embodiment, when adjusting the distance between the first frame 110 and the second frame 120, the operator loosens the connecting bolts and applies a pushing force to the reinforcing beam 123, pushing the reinforcing beam 123 to move along the first direction. During this process, the reinforcing beam 123 drives the support part 161 to move synchronously. The connecting part 162, driven by the support part 161, moves relative to the support column 133 along the first direction and approaches the first frame 110. The position of the connecting bolts within the slot 162-1 changes. After the distance between the first frame 110 and the second frame 120 reaches the target value, the operator stops pushing the reinforcing beam 123, tightens the connecting bolts, and locks the relative position of the second frame 120 and the connecting frame 130.

[0113] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
