[0078] Please refer to Figures 1 to 12 The embodiment provides a PCB board throwing machine compatible with multiple carriers and trolleys, which comprises a rack 1, two inlet and outlet stations, a carrier temporary storage station, an empty carrier recycling position, a separator paper recycling position and a PCB output station are arranged in the rack 1, the two inlet and outlet stations are arranged side by side, the carrier temporary storage station is located directly above the left inlet and outlet station, and the empty carrier recycling position is located directly above the right inlet and outlet station.

[0079] The lower end of each of the two inlet and outlet stations is provided with a carrier lifting mechanism 2, the left carrier lifting mechanism 2 receives the tray carrier 200 conveyed by the low trolley 100 and lifts the tray carrier 200 to the carrier temporary storage station, and the right carrier lifting mechanism 2 conveys the empty tray carrier 200 temporarily stored on the empty carrier recycling position to the low trolley 100, so as to realize feeding and discharging of the tray carrier 200 by cooperating with the low trolley 100.

[0080] The upper end of each of the two import and export stations is provided with a carrier conveying mechanism 3, and each of the two carrier conveying mechanisms 3 can receive the L-shaped carrier 400 or the box carrier 500 conveyed by the high trolley 300, so as to realize feeding and discharging by using the high trolley 300 and the L-shaped carrier 400 or the box carrier 500. When the L-shaped carrier 400 or the box carrier 500 using any one of the carrier conveying mechanisms 3 takes out the boards and exits in the original path, the L-shaped carrier 400 or the box carrier 500 can be directly placed on the other carrier conveying mechanism 3, so as to ensure continuous feeding of the boards.

[0081] The carrier temporary storage station is provided with a carrier unclamping temporary storage mechanism 4, the carrier unclamping temporary storage mechanism 4 temporarily stores a plurality of (for example, 10) tray carriers 200 lifted to the carrier temporary storage station and performs unclamping operation on the topmost tray carrier 200, so as to release the clamps on the tray carrier 200 from the boards 600. Since the carrier unclamping temporary storage mechanism can temporarily store a plurality of (for example, 10) tray carriers 200 at one time, it can realize non-stop feeding of the boards.

[0082] The empty carrier recycling station is provided with an empty carrier recycling mechanism 5, and the empty carrier recycling mechanism 5 is used to temporarily store a plurality of (for example, 10 or more) empty tray carriers 200.

[0083] The baffle paper recycling station is provided with a baffle paper drawer 6 used to store baffle paper, and the baffle paper drawer 6 is slidingly connected with the rack 1. When the baffle paper drawer 6 is full of baffle paper, the baffle paper drawer 6 can be manually pulled out and the baffle paper stored in the baffle paper drawer 6 can be taken out.

[0084] The rack 1 is provided with a transplanting mechanical hand mechanism 7, which places the boards 600 in the tray carrier 200 at the carrier temporary storage station or the boards 600 in the L-shaped carrier 400 or the box carrier 500 at the carrier conveying mechanism 3 to the PCB output station. After the transplanting mechanical hand mechanism 7 places the boards 600 in the tray carrier 200 at the carrier temporary storage station to the PCB output station, the empty tray carrier 200 also needs to be placed in the empty carrier recycling mechanism 5 for temporary storage. When the empty carrier recycling mechanism 5 is full of empty tray carriers 200, the carrier lifting mechanism 2 located directly below the empty carrier recycling mechanism 5 conveys the empty tray carrier 200 to the low trolley 100. In addition, if there is baffle paper in the L-shaped carrier 400 or the box carrier 500 at the carrier conveying mechanism 3 (usually, in order to avoid the boards 600 in the L-shaped carrier 400 or the box carrier 500 from rubbing against each other, a piece of baffle paper is placed between the boards 600), after the transplanting mechanical hand mechanism 7 places the boards 600 in the L-shaped carrier 400 or the box carrier 500 at the carrier conveying mechanism 3 to the PCB output station, the baffle paper in the L-shaped carrier 400 or the box carrier 500 also needs to be placed on the baffle paper drawer 6 at the baffle paper recycling station.

[0085] The PCB output station is provided with a PCB conveying mechanism 8, which conveys the PCB 600 in the output station to the main process line for subsequent production process.

[0086] The frame 1 is externally provided with a dustproof cover 9, which covers the frame 1 and is used to avoid dust pollution of the PCB 600 when the PCB is put in, thereby providing a dust-free environment. The dustproof cover 9 is provided with an output opening 901 corresponding to the PCB output station, and an automatic door mechanism 10 corresponding to the import and export stations. The output opening 901 is used for the PCB conveying mechanism 8 to dock with the main process line. The automatic door mechanism 10 is used to automatically open when the low cart 100 or the high cart 300 is loaded or unloaded, so as to facilitate the carrier on the low cart 100 or the high cart 300 to enter and exit the equipment.

[0087] The automatic door mechanism 10 includes a door frame 1001, two upper and lower sliding doors 1002 arranged at the lower end of the door frame 1001 and corresponding to the positions of the two carrier lifting mechanisms 2 respectively, and two left and right sliding doors 1003 arranged at the upper end of the door frame 1001 and corresponding to the positions of the two carrier conveying mechanisms 3 respectively. The upper and lower sliding doors 1002 are located in front of the left and right sliding doors 1003 to avoid affecting the sliding of the upper and lower sliding doors 1002. The interval between the two left and right sliding doors 1003 is not less than the width of the left and right sliding doors 1003, so that the two left and right sliding doors 1003 can be slid to the middle and hidden behind the door frame 1001 when opened. The automatic door mechanism 10 described above includes two upper and lower sliding doors 1002 and two left and right sliding doors 1003, which can realize the entry and exit of four stations and adapt to the low cart 100 and the high cart 300. When the low cart 100 using the transport tray carrier 200 is used, the upper and lower sliding doors 1002 are slid upward to open, so that the low cart 100 can enter the equipment. When the high cart 300 using the transport L-shaped carrier 400 or the box carrier 500 is used, the corresponding left and right sliding doors 1003 are slid to the middle to open, and then the L-shaped carrier 400 or the box carrier 500 is manually pushed into the equipment.

[0088] Please refer to Figures 5 to 7In the embodiment, the carrier conveying mechanism 3 comprises two carrier conveying modules symmetrically arranged left and right. The carrier conveying module comprises a roller slide rail 301 for receiving the L-shaped carrier 400, a support edge 302 arranged above the outer side of the roller slide rail 301 for receiving the box carrier 500, and a first avoidance air cylinder 303 arranged on the outer side of the bottom of the roller slide rail 301. The movable end of the first avoidance air cylinder 303 is connected with the roller slide rail 301 and drives the roller slide rail 301 and the support edge 302 to move back and forth synchronously left and right. The end of the roller slide rail 301 is provided with a first arrival blocking block 304 for limiting the plate taking position of the L-shaped carrier 400 to achieve accurate plate taking. The outer side above the head of the roller slide rail 301 is provided with a clamping air cylinder 306 fixed on the outer side of the support edge 302. The telescopic end of the clamping air cylinder 306 is provided with a rotary air cylinder 307, and the movable end of the rotary air cylinder 307 is provided with a clamping block 308. The support edge 302 is provided with an avoidance opening 3021 through which the clamping block 308 passes. The top of the head of the support edge 302 is provided with a downward inclined lead-in slope 3022, which enables the box carrier 500 to be smoothly pushed onto the two support edges 302. The inner side of the end of the support edge 302 is provided with a second arrival blocking block 309 for limiting the plate taking position of the box carrier 500 to achieve accurate plate taking.

[0089] When the L-shaped carrier 400 is used to place the board, the two first avoidance air cylinders 303 are extended to drive the two roller slide rails 301 and the two support edges 302 to approach each other, so that the distance between the two roller slide rails 301 is adapted to the width of the L-shaped carrier 400. Then the L-shaped carrier 400 is pushed from the high cart 300 onto the two roller slide rails 301. After positioning, the rotary air cylinder 307 rotates the clamping block 308 to the front side of the L-shaped carrier 400. Then the clamping air cylinder 306 drives the clamping block 308 to move backward to clamp the L-shaped carrier 400 in cooperation with the first arrival blocking block 304, so that the L-shaped carrier 400 is positioned on the carrier conveying mechanism 3. Then the plate taking mechanism 7 is waited for. After all the PCB boards 600 on the L-shaped carrier 400 are taken away, the rotary air cylinder 307 and the clamping air cylinder 306 are reset, and the empty L-shaped carrier 400 can be taken out at this time.

[0090] When the box carrier 500 is used to place the board, the two first avoidance air cylinders 303 are extended to drive the two roller slide rails 301 and the two support edges 302 to approach each other, so that the distance between the two support edges 302 is adapted to the width of the box carrier 500. Then the box carrier 500 is pushed from the high cart 300 onto the two support edges 302. After positioning, the box carrier 500 can be positioned on the carrier conveying mechanism 3, and the plate taking mechanism 7 is waited for.

[0091] When using the pallet carrier 200 to drop a pallet, the two first clearance cylinders 303 retract, causing the two roller slides 301 and the two support edges 302 to move away from each other, making room for the pallet carrier 200.

[0092] The aforementioned carrier conveying mechanism 3 has an ingenious structural design. By setting up roller slide rail 301, support side 302, and first clearance cylinder 303, it can be compatible with L-frame carrier 400 and box carrier 500. Furthermore, the roller slide rail 301 and support side 302 can be retracted by the first clearance cylinder 303 to make room for pallet carrier 200. This ensures that the carrier conveying mechanism 3 and the carrier lifting mechanism 2 can be installed at the same inlet / outlet station without interfering with each other. Thus, a single inlet / outlet station can accommodate different trolleys and carriers. Different carriers and trolleys do not need to be handled separately at multiple inlet / outlet stations, which can reduce the size of the equipment and save space and production costs.

[0093] Please see Figure 8 , Figure 9 In this embodiment, the carrier opening and clamping temporary storage mechanism 4 includes two carrier opening and clamping temporary storage modules arranged symmetrically at left and right intervals. The carrier opening and clamping temporary storage module includes a straightening bracket 401 for supporting and clamping several (e.g., 10) pallet carriers 200 lifted to the carrier temporary storage station, a second clearance cylinder 402 disposed outside the straightening bracket 401, an opening module 403 disposed at the front and rear ends of the straightening bracket 401 for opening the clamps on the pallet carrier 200, and a third clearance cylinder 404 disposed outside the opening module 403. The movable end of the second clearance cylinder 402 is connected to the straightening bracket 401 and drives the straightening bracket 401 to move back and forth left and right. The movable end of the third clearance cylinder 404 is connected to the opening module 403 and drives the opening module 403 to move back and forth left and right. Specifically, the clamping module 403 includes a vertically arranged clamping cylinder 4031 and a clamping block 4032. The movable end of the clamping cylinder 4031 is connected to the clamping block 4032 and drives the clamping block 4032 to press against the pressing end of the clamp on the pallet carrier 200.

[0094] When using the pallet carrier 200 to deliver the pallet, the pallet carrier 200 is lifted to the temporary storage position via the carrier lifting mechanism 2 on the left. Two second clearance cylinders 402 extend and drive two straightening brackets 401 to move closer to each other until the two straightening brackets 401 hold and clamp several (e.g., 10) pallet carriers 200 that have been lifted to the temporary storage position. At the same time, four third clearance cylinders 404 extend and drive four clamping modules 403 to move closer to each other until the four clamping modules 403 move to the top pallet carrier 200 and above the four corresponding clamps. Then, the clamping cylinders 4031 of the four clamping modules 403 extend the clamping blocks 4032, which press the clamping blocks 4032 against the pressing end of the corresponding clamp on the top pallet carrier 200, so that the clamp on the top pallet carrier 200 releases the PCB board 600, and then waits for the transfer robot arm mechanism 7 to pick up the board.

[0095] When using the L-frame carrier 400 or the box carrier 500 to throw the plate, the two second clearance cylinders 402 retract and drive the two straightening brackets 401 to move away from each other, and the four third clearance cylinders 404 retract and drive the four clamping modules 403 to move away from each other, making room for the L-frame carrier 400 or the box carrier 500.

[0096] The aforementioned carrier opening and clamping temporary storage mechanism 4 has an ingenious structural design. By setting up a straightening bracket 401, a second clearance cylinder 402, an opening module 403, and a third clearance cylinder 404, it can straighten the position of the pallet carrier 200 and accurately open the pallet carrier 200. Furthermore, the straightening bracket 401 and the opening module 403 can be retracted by the second clearance cylinder 402 and the third clearance cylinder 404 to make room for the L-frame carrier 400 or the box carrier 500. This ensures that the carrier opening and clamping temporary storage mechanism 4, installed above the carrier conveying mechanism 3 on the left side, will not interfere with each other. This allows a single inlet / outlet station to be compatible with different trolleys and carriers. Different carriers and trolleys do not need to be processed separately at multiple inlet / outlet stations, which can reduce the size of the equipment and save space and production costs.

[0097] Please see Figure 10 , Figure 11 In this embodiment, the empty vehicle recovery mechanism 5 includes two empty vehicle recovery modules symmetrically arranged at left and right intervals. The empty vehicle recovery module includes an empty vehicle bracket 501 for supporting several empty pallet carriers 200 and a fourth avoidance cylinder 502 disposed on the outside of the empty vehicle bracket 501. The movable end of the fourth avoidance cylinder 502 is connected to the empty vehicle bracket 501 and drives the empty vehicle bracket 501 to move back and forth left and right.

[0098] When the tray carrier 200 is used to place the PCB board 600, the two fourth avoidance cylinders 502 are extended to drive the two empty carrier brackets 501 to approach each other, so that the distance between the two empty carrier brackets 501 is adapted to the width of the tray carrier 200, and then the empty tray on the carrier temporary storage position is grabbed by the transplanting mechanical hand mechanism 7 and placed on the two empty carrier brackets 501 for temporary storage.

[0099] When the L-shaped carrier 400 or the box carrier 500 is used to place the PCB board 600, the two fourth avoidance cylinders 502 are retracted to drive the two empty carrier brackets 501 to move away from each other, so as to leave space for the L-shaped carrier 400 or the box carrier 500.

[0100] The empty carrier recycling mechanism 5 has a clever structure, and the empty tray carrier 200 can be temporarily stored by setting the empty carrier bracket 501 and the fourth avoidance cylinder 502. The fourth avoidance cylinder 502 can retract the empty carrier bracket 501 to leave space for the L-shaped carrier 400 or the box carrier 500, so that the empty carrier recycling mechanism 5 installed above the carrier conveying mechanism 3 on the right side will not affect each other, thereby realizing that one import and export position is compatible with different trolleys and carriers. Different carriers and trolleys do not need to be processed separately in multiple import and export positions, which can reduce the size of the equipment, save the occupied space and production cost.

[0101] Please refer to Figure 3 、 Figure 4 In the embodiment, the transplanting mechanical hand mechanism 7 includes a first mechanical hand 701, a second mechanical hand 702, and a mechanical hand moving module 703. The movable end of the mechanical hand moving module 703 is connected with the first mechanical hand 701 and the second mechanical hand 702 respectively. The mechanical hand moving module 703 drives the first mechanical hand 701 and the second mechanical hand 702 to move back and forth along the parallel direction of the two import and export positions. The end of the first mechanical hand 701 is provided with a first suction cup 704 for grabbing the PCB board 600. The end of the second mechanical hand 702 is provided with a second suction cup 705 for grabbing the tray carrier 200 or the partition paper. The first suction cup 704 and the second suction cup 705 are both provided with a width adjusting mechanism to adapt to different sizes of the PCB board 600, the tray carrier 200, and the partition paper.

[0102] When the tray carrier 200 is used to place the PCB, the tray carrier 200 is lifted to the carrier temporary storage station by the left carrier lifting mechanism 2, the carrier opening and clamping temporary storage mechanism 4 supports the tray carrier 200 lifted to the carrier temporary storage station and performs the opening and clamping operation, so that the clamps on the tray carrier 200 are loosened from the PCB 600, and then the first mechanical hand 701 cooperates with the mechanical hand moving module 703 and the first suction disc 704 to place the PCB 600 on the tray carrier 200 to the PCB output station, and then the second mechanical hand 702 cooperates with the mechanical hand moving module 703 and the second suction disc 705 to place the empty tray carrier 200 on the empty carrier recycling mechanism 5.

[0103] When the L-shaped carrier 400 and the box carrier 500 are used to place the PCB, the first mechanical hand 701 cooperates with the mechanical hand moving module 703 and the first suction disc 704 to place the PCB 600 in the L-shaped carrier 400 or the box carrier 500 on the carrier conveying mechanism 3 to the PCB output station, and then the second mechanical hand 702 cooperates with the mechanical hand moving module 703 and the second suction disc 705 to place the partition paper in the L-shaped carrier 400 or the box carrier 500 to the partition paper recycling station.

[0104] The above-mentioned transplanting mechanical hand mechanism 7 has a clever structure design, by setting the first mechanical hand 701, the second mechanical hand 702 and the mechanical hand moving module 703, the placing efficiency is greatly improved.

[0105] Please refer to Figure 13 、 Figure 14In the embodiment, the left and right sides of the up-down sliding door 1002 are provided with up-down transmission belts 1004, one side of the up-down transmission belt 1004 is connected with the corresponding side of the up-down sliding door 1002 through a first connecting piece 1005, and the transmission wheels at the top of the two up-down transmission belts 1004 are connected with the driving shaft of a servo motor 1007 through a synchronous mechanism 1006 (such as a synchronous belt) for transmission. After the servo motor 1007 is started, the two up-down transmission belts 1004 are synchronously driven to rotate through the synchronous mechanism 1006, and then the up-down sliding door 1002 is driven to slide up and down through the first connecting piece 1005 on the two up-down transmission belts 1004, so as to realize opening and closing. In order to make the up-down sliding door 1002 slide up and down stably, one side of the up-down transmission belt 1004 is provided with an up-down sliding rail 1008, the first connecting piece 1005 is slidingly connected with the up-down sliding rail 1008 and can slide up and down along the up-down sliding rail 1008. Meanwhile, the highest stroke of the up-down sliding door 1002 is provided with a first arrival sensor 1009 for sensing whether the up-down sliding door 1002 reaches the highest stroke, when the first arrival sensor 1009 senses that the up-down sliding door 1002 reaches the highest stroke, the first arrival sensor 1009 sends a corresponding signal, and the servo motor 1007 stops rotating, at this time, the up-down sliding door 1002 is completely opened, after the low cart 100 sends the tray carrier 200 into the equipment, the servo motor 1007 reversely rotates to drive the up-down sliding door 1002 to slide down and close the up-down sliding door 1002. Through the up-down transmission belt 1004, the first connecting piece 1005, the synchronous mechanism 1006, the servo motor 1007, the up-down sliding rail 1008 and the first arrival sensor 1009 arranged above, the up-down sliding door 1002 can be precisely and stably opened and closed, has large bearing capacity, simple structure and low production cost.

[0106] Please refer to Figure 13Further, since the up-down sliding door 1002 is located in front of the left-right sliding door 1003, and the up-down sliding door 1002 has a certain thickness, when the high trolley 300 stops in front of the up-down sliding door 1002, there is a distance between the L-frame carrier 400 on the high trolley 300 and the carrier conveying mechanism 3, and it is difficult to align the L-frame carrier 400 to be pushed into or out of the carrier conveying mechanism 3. Therefore, the auxiliary rollers 1010 are arranged on the left and right sides of the top of the up-down sliding door 1002, the height of the auxiliary rollers 1010 is consistent with the height of the roller sliding rail 301 on the carrier conveying mechanism 3, and the auxiliary rollers 1010 can assist in manually pushing the L-frame carrier 400 on the high trolley 300 into the carrier conveying mechanism 3 or pushing the empty L-frame carrier 400 on the carrier conveying mechanism 3 back to the high trolley 300. Meanwhile, a guide limiting ring 1011 is arranged outside the auxiliary rollers 1010, the outer diameter of the guide limiting ring 1011 is greater than the diameter of the auxiliary rollers 1010, the guide limiting ring 1011 is fixed with the auxiliary rollers 1010, and the guide limiting ring 1011 can limit the position of the L-frame carrier 400 entering or leaving the equipment, and plays a guiding role.

[0107] Please refer to Figure 13 Further, the high trolley locking mechanism 1012 is arranged on the top front side of the up-down sliding door 1002, so that the high trolley 300 does not slide randomly when the L-frame carrier 400 or the box carrier 500 on the high trolley 300 is manually pushed into the equipment or the L-frame carrier 400 or the box carrier 500 on the carrier conveying mechanism 3 is pushed back to the high trolley 300. Since the high trolley locking mechanism 1012 is prior art, the specific structure and working principle thereof will not be described in detail, and those skilled in the art can freely select prior art.

[0108] Please refer to Figure 13 Further, the high trolley buffer block 1013 is arranged on the top front side of the up-down sliding door 1002, which can prevent the high trolley 300 from directly colliding with the up-down sliding door 1002, thereby causing damage. Preferably, the high trolley buffer block 1013 is provided with two blocks and is arranged on the left and right sides of the high trolley locking mechanism 1012.

At the same time, the left and right sides of the left and right slide rails 1016 of the left and right sliding door 1003 are respectively provided with third position sensors 1018 for sensing whether the left and right sliding door 1003 is in place. When the left and right sliding door 1003 slides to the left to the maximum stroke, the left third position sensor 1018 sends a corresponding signal, and the linear drive cylinder 1014 stops; when the left and right sliding door 1003 slides to the right to the maximum stroke, the right third position sensor 1018 sends a corresponding signal, and the linear drive cylinder 1014 stops, so as to realize accurate opening and closing of the left and right sliding door 1003.
