[0033] like Figure 1 , 2 , 3, and 6, the PCB board temporary storage machine provided by the embodiment of the present invention is now described. The PCB board temporary storage machine includes a temporary storage device 30 and a conveying mechanism 10 for conveying PCB boards 40, and the temporary storage device 30 includes a transfer mechanism 20, a temporary storage drive component 31, and a plurality of temporary storage structures 32 arranged in a predetermined direction; in the same temporary storage device 30, the output end of the temporary storage drive component 31 is connected to the temporary storage structure 32 to drive the temporary storage structure 32 to move in a predetermined direction and make one of the temporary storage structures 32 at a predetermined position (the predetermined position is located on the side of the conveying mechanism 10 and is roughly flush with the horizontal plane of the conveying mechanism 10 conveying the PCB board 40), and the transfer mechanism 20 is used to transfer the PCB board 40 between the conveying mechanism 10 and the temporary storage structure 32 at the predetermined position.

[0034] Compared with the prior art, the PCB board temporary storage machine provided by the embodiment of the present invention has a same temporary storage device 30. Since each temporary storage structure 32 can be moved along a predetermined direction under the drive of the temporary storage drive component 31 and one of the temporary storage structures 32 is located at a predetermined position, in the process of temporarily storing PCB boards 40, a plurality of PCB boards 40 are circulated on the conveying mechanism 10, and the transfer mechanism 20 transfers a PCB board 40 on the conveying mechanism 10 to the temporary storage structure 32 at a predetermined position, and then the temporary storage drive component 31 drives the temporary storage structure 32 to move along a predetermined direction, so that the next temporary storage structure 32 is located at a predetermined position to prepare to receive the next PCB board 40, and at the same time the transfer mechanism 20 moves to the original position to prepare to transfer the next PCB board 40, and the cycle continues. When the number of PCB boards 40 stored on the temporary storage structure 32 reaches a certain number, the PCB boards 40 placed on the first temporary storage structure 32 have also reached the specified temporary storage time. At this time, the temporary storage drive component 31 drives the PCB boards 40 placed on the first temporary storage structure 32 to be located at a predetermined position, and the transfer mechanism 20 begins to take out the first PCB board 40 placed from the temporary storage structure 32 to the conveying mechanism 10 to be conveyed to the next process, and then the PCB board 40 on the second temporary storage structure 32 is taken out and transferred to the conveying mechanism 10, and the PCB boards 40 located on other temporary storage structures 32 are taken out in a cycle in this way; thereby, the PCB boards 40 can be taken out from the temporary storage device 30 and placed on the conveying mechanism 10 to be conveyed to the next process, and at the same time, the PCB boards 40 that have not been temporarily stored on the conveying mechanism 10 can be transferred to the temporary storage device 30 for temporary storage, so as to realize uninterrupted storage and taking out of the PCB boards 40, and effectively improve the temporary storage processing efficiency of the PCB boards 40.

[0035] In another embodiment of the present invention, the temporary storage driving assembly 31 drives the temporary storage structure 32 to move along a predetermined direction, which may be a vertical up and down direction.

[0036] In another embodiment of the present invention, Figure 1 , 2As shown in Figures 3 and 6, at least two temporary storage devices 30 are arranged along the conveying direction of the conveying mechanism 10, wherein the transfer mechanism 20 of one temporary storage device 30 is used to transfer the PCB board 40 to be temporarily stored from the conveying mechanism 10 to the corresponding temporary storage structure 32, and the transfer mechanism 20 of the other temporary storage device 30 is used to transfer the temporarily stored PCB board 40 from the corresponding temporary storage structure 32 to the conveying mechanism 10. Specifically, at least two temporary storage devices 30 are arranged in the conveying direction of the conveying mechanism 10. The temporary storage device 30 located near the input end of the conveying mechanism 10 is used to store the PCB board 40. The PCB board 40 that has been temporarily stored is taken out from the temporary storage device 30 located near the output end of the conveying mechanism 10 to the conveying mechanism 10 to be transported to the next process. The two temporary storage devices 30 cooperate with each other. The temporary storage device 30 located near the output end of the conveying mechanism 10 first stores and retrieves the PCB board 40. After the temporary storage structure 32 stores and retrieves a certain number of PCB boards 40, the PCB board 40 placed in the first temporary storage structure 32 reaches the temporary storage time. At this time, the transfer mechanism 20 on the temporary storage device 30 starts to take out the PCB board 40 from its temporary storage structure 32 to the conveying mechanism 10 to output it to the next process; at the same time, the temporary storage structure 32 located near the input end of the conveying mechanism 10 starts to store and retrieve the PCB board 40. By analogy, each temporary storage device 30 cooperates with each other, so that the temporary storage device 30 relatively close to the output end of the conveying mechanism 10 continuously places the temporarily stored PCB board 40 on the conveying mechanism 10 for conveying to the next process, and the temporary storage device 30 relatively close to the input end of the conveying mechanism 10 continuously transfers the PCB board 40 from the conveying mechanism 10 to its temporary storage structure 32 for temporary storage processing, realizing uninterrupted storage and removal of the PCB board 40, greatly improving the temporary storage processing efficiency of the PCB board 40. The problem that the existing solar PCB board temporary storage machine cannot temporarily store a large number of thinner PCB boards for a long time is solved, and the order of controlling the entry and exit of PCB boards according to the requirements of the process can be realized.

[0037] In another embodiment of the present invention, Figure 3 , 7 As shown, the temporary storage structure 32 includes at least two temporary storage bar bars 321, which are arranged at intervals and located in the same plane to form a temporary storage support surface. Specifically, when storing the PCB board 40, by arranging the temporary storage bar bars 321 side by side to form a temporary storage support surface, it is not only convenient to place the PCB board 40, but also can effectively reduce the contact area between the temporary storage bar bars 321 and the PCB board 40, thereby reducing the damage to the board surface of the PCB board 40 caused by contact.

[0038] In another embodiment of the present invention, the temporary storage bar 321 is cylindrical. Specifically, by making the temporary storage bar 321 cylindrical, not only can the contact position between the PCB board 40 and the temporary storage bar 321 be smooth, which can effectively reduce the damage to the PCB board 40; and because the temporary storage bar 321 and the PCB board 40 are in "line contact", the contact area can be reduced more than the "surface contact" of the square temporary storage bar 321, thereby achieving the effect of protecting the PCB board 40.

[0039] In another embodiment of the present invention, Figure 3 , 4 As shown, the temporary storage device 30 also includes a temporary storage bracket 322, the temporary storage bar 321 is connected to the temporary storage bracket 322, and the output end of the temporary storage drive component 31 is connected to the temporary storage bracket 322. Specifically, by setting the temporary storage bracket 322, each temporary storage bar 321 is connected to the temporary storage bracket 322, so that the temporary storage bracket 322 can be driven to move up and down by the temporary storage drive component 31, and each temporary storage bar 321 can be driven to move at the same time, which can not only ensure the efficiency of movement, but also make each temporary storage support surface move smoothly without deviation, so as to ensure that the PCB board 40 can be stably placed during the movement.

[0040] In another embodiment of the present invention, Figure 3 , 7 As shown, there are multiple temporary storage bar bars 321, and the temporary storage bar bars 321 are distributed in a matrix to form multiple temporary storage support surfaces. Specifically, each temporary storage bar bar 321 is connected to a temporary storage bracket 322, and is distributed in a matrix in the horizontal direction and the vertical direction, so that each temporary storage support bar forms a temporary storage support surface in the horizontal direction, and these temporary storage support surfaces in the horizontal direction are evenly arranged in the vertical direction to form multiple temporary storage support surfaces for placing the PCB board 40. For example, 20 rows of temporary storage brackets 322 arranged along the horizontal direction can be set in the vertical direction, so that 20 temporary storage support surfaces arranged up and down are formed for placing the PCB board 40.

[0041] In another embodiment of the present invention, Figure 2 , 3As shown in Figures 7 and 8, the temporary storage drive assembly 31 includes a temporary storage motor 311, a temporary storage screw rod 312 and a temporary storage moving nut 313. The main shaft of the temporary storage motor 311 is connected to the temporary storage screw rod 312 and drives the temporary storage screw rod 312 to rotate. The temporary storage moving nut 313 is screwed to the temporary storage screw rod 312, and the temporary storage moving nut 313 is connected to the temporary storage bracket 322. Specifically, in driving the temporary storage bar rod 321 to move up and down, the temporary storage motor 311 drives the temporary storage screw rod 312 to rotate, so that the temporary storage screw rod 312 drives the temporary storage moving nut 313 to move up and down, and the temporary storage moving nut 313 drives the temporary storage bracket 322 to move up and down synchronously, thereby driving each temporary storage bar rod 321 (i.e., the temporary storage support surface) to move up and down. Among them, guide shafts 314 extending in the same direction as the temporary storage screw rod 312 can be arranged on both sides of the temporary storage screw rod 312, and the temporary storage bracket 322 is slidably connected with the guide shafts 314, so that the guide shafts 314 can assist the temporary storage bracket 322 to move up and down, ensuring that the temporary storage bracket 322 moves smoothly. When the temporary storage motor 311 drives the temporary storage screw rod 312 to rotate, a coupling 315 can be arranged between the main shaft of the temporary storage motor 311 and the temporary storage screw rod 312, so that the temporary storage screw rod 312 rotates more smoothly.

[0042] In another embodiment of the present invention, Figure 1 , 2As shown, the conveying mechanism 10 includes a plurality of conveying rollers 11 extending along a predetermined direction. The conveying rollers 11 are arranged at intervals and rotate in the same direction. The conveying rollers 11 are used to convey the PCB board 40. Specifically, each conveying roller 11 is arranged along a predetermined direction to form a conveying channel. Each conveying roller 11 rotates in the same direction, thereby forming a conveying channel that flows along a fixed direction. When the PCB board 40 flows on the conveying channel, the PCB board 40 flows on each conveying roller 11. When the PCB board 40 flows to the position of the transfer mechanism 20, the transfer mechanism 20 passes through the gaps between the conveying rollers 11 from below, and rises to the top of each conveying roller 11, thereby lifting the PCB board 40 on the conveying roller 11, and then transferring it to the temporary storage structure 32 for temporary storage; similarly, the transfer mechanism 20 passes through the temporary storage structure 32, and the PCB board 40 on the conveying roller 11 is lifted. When the PCB board 40 is transferred from the structure 32 to the conveying roller 11, the transfer mechanism 20 first passes through the gaps between the temporary storage bar bars 321 and rises to the top of the temporary storage bar bars 321, thereby lifting the PCB board 40 on the temporary storage bar bars 321, and then transferring it to the top of each conveying roller 11. At this time, the transfer mechanism 20 drives the PCB board 40 to move downward, so that the transfer mechanism 20 drops to the bottom of each conveying roller 11 at the gaps between each conveying roller 11, so that the PCB board 40 on the transfer mechanism 20 is placed on the conveying roller 11, thus achieving transfer. Among them, when driving the above-mentioned conveying rollers 11 to rotate synchronously in the same direction, they are connected to each conveying roller 11 through a transmission shaft, and the transmission shaft and each conveying roller 11 are connected through a gear module to drive each conveying roller 11 to rotate. The transmission shaft is driven to rotate by a motor, and the rotation shaft and the main shaft of the motor can be driven by a synchronous wheel and a synchronous belt.

[0043] In another embodiment of the present invention, the conveying mechanism 10 is a mature conveying roller conveying mechanism on the market.

[0044] In another embodiment of the present invention, Figure 4 , 5As shown in Figures 6 and 7, the transfer mechanism 20 includes a transfer lifting assembly 21 and a translation assembly 22. The lifting end of the transfer lifting assembly 21 is connected to the translation assembly 22 and drives the translation assembly 22 to lift and lower in the gap between the conveying rollers 11 along the vertical direction (X direction in the figure). The translation assembly 22 is used to transfer the PCB board 40 between the conveying mechanism 10 and the temporary storage support surface (Y direction in the figure). Specifically, when the transfer mechanism 20 transfers the PCB board 40, the translation assembly 22 is used to support the PCB board 40. The transfer lifting assembly 21 drives the translation assembly 22 to move up and down in the gap between each conveying roller 11, and to move up and down in the gap between each temporary storage bar 321, so that the PCB board 40 located on the translation assembly 22 can be placed on each temporary storage bar 321 or each conveying roller 11, and the PCB board 40 located on the translation assembly 22 can be taken out from each temporary storage bar 321 or each conveying roller 11. The translation assembly 22 drives the PCB board 40 to move between the temporary storage structure 32 and the transfer mechanism 20. When the PCB board 40 needs to be stored on the temporary storage structure 32, the transfer lifting assembly 21 drives the translation assembly 22 to move upward from the bottom of the conveying roller 11 to lift the PCB board 40 located on the conveying roller 11. At this time, the translation assembly 22 drives the PCB board 40 to move toward the temporary storage structure 32, so that the PCB board 40 is located above the temporary storage bar 321. Then, the transfer lifting assembly 21 drives the translation assembly 22 to move downward between the gaps of the temporary storage bar 321, so that the PCB board 40 is placed. When the PCB board 40 needs to be taken out from the temporary storage structure 32, the transfer lifting assembly 21 drives the translation assembly 22 to move upward from the bottom of the temporary storage bar 321 to lift the PCB board 40 on the temporary storage bar 321. At this time, the translation assembly 22 drives the PCB board 40 to move toward the conveying roller 11, so that the PCB board 40 is located above the conveying roller 11, and then the transfer lifting assembly 21 drives the translation assembly 22 to move downward between the gaps between the conveying rollers 11, so that the PCB board 40 is placed on the conveying roller 11 to be conveyed to the next process.

[0045] In another embodiment of the present invention, Figure 5 , 8As shown in , 9, the translation assembly 22 includes a translation bracket 221, a translation motor 222, a translation screw 223, a translation nut 224, a transfer support 225 and at least two transfer bar rods 226. The translation screw 223 is rotatably mounted on the translation bracket 221, the translation motor 222 is connected to the translation screw 223 and drives the translation screw 223 to rotate, the translation nut 224 is screwed to the translation screw 223, one end of the transfer support 225 is mounted on the translation nut 224, and each transfer bar rod 226 is mounted on the other end of the transfer support 225. The transfer bar rods 226 are arranged at intervals and are located in the same plane to form a transfer support surface, and the translation bracket 221 is connected to the lifting end of the transfer lifting assembly 21. Specifically, the transfer support 225 includes a plurality of support plates 2251 corresponding to the transfer bar 226, each support plate 2251 is connected to each transfer bar 226 in a one-to-one correspondence, and the transfer bar 226 and the support plate 2251 are in a vertical state, and the transfer bar 226 connected to the transfer support 225 is located in the same horizontal plane to form a transfer support surface. The support plate 2251 is flat, so that the transfer bar 226 can be driven to move up and down in the gap between the conveying rollers 11, and in the gap between the temporary storage bar 321. When the transfer bar 226 moves up and down in the gap between the conveying rollers 11, and in the gap between the temporary storage bar 321, the PCB board 40 is supported or put down, and then the purpose of transferring the PCB board 40 is achieved between the conveying roller 11 and the temporary storage bar 321 under the drive of the translation movement nut 224.

[0046] In another embodiment of the present invention, the transfer bar 226 is a cylindrical bar, which not only makes the contact position between the PCB board 40 and the transfer bar 226 smooth during the transfer of the PCB board 40, effectively reducing the damage to the PCB board 40; but also because there is "line contact" between the transfer bar 226 and the PCB board 40, the contact area can be reduced more than the "surface contact" of the square transfer bar 226, thereby achieving the effect of protecting the PCB board 40.

[0047] In another embodiment of the present invention, Figure 5 , 6As shown in , 8, the transfer lifting assembly 21 includes a cylinder 211, the stroke rod of the cylinder 211 is vertically arranged, and the stroke rod of the cylinder 211 is connected to the translation bracket 221. Specifically, when driving the translation assembly 22 to move up and down, the cylinder 211 is extended and retracted up and down through the stroke rod, thereby driving the translation bracket 221 to move up and down, and the translation bracket 221 synchronously drives the transfer support 225 to move up and down, so as to achieve the simultaneous up and down movement of each transfer bar 226. Among them, a sliding module can also be set to assist the translation bracket 221 to move up and down. The sliding module includes a guide rail and a slider slidably connected to the guide rail. The guide rail is vertically arranged, and the slider is connected to the translation bracket 221, so that the translation bracket 221 is more stable during the up and down movement.
