Description

Technical Field

[0001] This invention relates to the field of plate take-up and take-down machines, and in particular to an automatic plate take-up and take-down machine. Background Technology

[0002] The processing of circuit boards and other PCBs typically involves multiple steps, sometimes requiring board loading and unloading between steps. Currently, board loading and unloading are primarily performed using board loading and unloading machines. With societal development and progress, board loading and unloading machines have become widely used and popular, and the demand for their production efficiency is increasing. While existing machines can automate board loading and unloading, their functions are relatively simple, making it difficult to adjust the orientation of the conveyed boards.

[0003] Among existing patents, Chinese patent application number 202222053771.X discloses an automatic board handling machine suitable for material bins, including a frame, a positioning mechanism, and a board picking and transferring mechanism. The frame has a picking port on its front side that cooperates with the material bin, and a discharging port on its back side. The positioning mechanism is installed on the front of the frame and below the picking port. The positioning mechanism receives the material bin from the transport trolley and positions it, then transports the bin to the picking port. The board picking and transferring mechanism is installed inside the frame. It picks up the board from the material bin at the picking port and moves the board between the picking port and the discharging port. This patent provides an automated board handling machine that handles the boards in the material bin, improving the automation level and efficiency of board production. To a certain extent, it avoids the possibility of damage to the boards caused by manual labor. However, the discharging mechanism can only simply transport the boards, its function is limited, and it cannot adjust the placement angle of the transported boards, making it difficult to directly match with external equipment. Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0016] The beneficial effects of this invention are as follows: In practical applications, the board is supplied to the board feeding device, which transports the board to the top of the pallet rotating device. The pallet rotating device then lifts the board, causing it to detach from the feeding surface of the board feeding device and be positioned within the clamping mechanism. The board is then driven to rotate by a preset angle to adjust its placement angle. The clamping mechanism then clamps the board after the angle adjustment, positioning it above the board feeding device. Next, the position angle adjustment device adjusts the position and angle of the pick-and-place device, aligning it with the clamped board and extending it between the board and the board feeding device. This allows the pick-and-place device to stably pick up the board. Finally, the position angle adjustment device adjusts the position and angle of the pick-and-place device. The position and angle of the board are adjusted so that the board pick-and-place device and the board are first centered, and then the angle of the board is adjusted (e.g., rotating the board 180°). Simultaneously, a trolley or intelligent cart transports the material box to the material box positioning mechanism. The material box positioning mechanism supports and positions the material box, and presses the box door against the door opening and lifting device. The door opening and lifting device opens and lifts the box door, aligning the board with the box body. The board pick-and-place device places the board into the insertion slot in the box body to achieve board collection. When the material box is full of boards, the door opening and lifting device closes the box door at the box opening. Finally, the material box positioning mechanism releases its positioning of the material box, and the trolley or intelligent cart can output the full material box. This invention uses a pallet rotation device and a clamping mechanism working together to move the board away from the board feeding device and adjust the placement angle of the board, facilitating accurate and stable board pick-and-place operations, thereby improving the stability of board collection and placement.

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0036] like Figures 1 to 16As shown, the present invention provides an automatic plate feeding and receiving machine, which includes a machine base 92, a plate feeding device 2 disposed within the machine base 92, a clamping mechanism 3 disposed above the plate feeding device 2, a pallet rotating device 4 disposed on the plate feeding device 2, a hopper positioning mechanism 5 disposed opposite to the plate feeding device 2, a plate picking and placing device 6 movably disposed between the hopper positioning mechanism 5 and the plate feeding device 2, a position angle adjustment device 7 driven and connected to the plate picking and placing device 6, and a door opening and lifting device 8 disposed on the side of the hopper positioning mechanism 5 near the plate picking and placing device 6. Mechanism 5 is used to position the material box 1, and the door opening and lifting device 8 is used to open or close the material box 1. The board feeding device 2 is provided with a pallet space 21, which is located within the clamping area of ​​the clamping mechanism 3. The pallet rotating end of the pallet rotating device 4 protrudes above the feeding surface of the board feeding device 2 via the pallet space 21. The position angle adjustment device 7 is used to adjust the position and angle of the board picking and placing device 6. The board picking and placing device 6 is used to transfer the board from the clamping mechanism 3 to the material box 1 positioned by the material box positioning mechanism 5 or to transfer the board from the material box 1 to the clamping mechanism 3. This embodiment can be used for both receiving and placing boards, and the board is preferably a circuit board.

[0037] This embodiment uses board receiving as an example for explanation. In practical applications, the board is supplied to the board feeding device 2, which transports the board to the top of the pallet rotating device 4. The pallet rotating device 4 then lifts the board, causing it to detach from the feeding surface of the board feeding device 2 and be positioned within the clamping mechanism 3. It then drives the board to rotate a preset angle to adjust its placement angle. The clamping mechanism 3 then clamps the adjusted board, positioning it above the board feeding device 2. Next, the position angle adjustment device 7 adjusts the position and angle of the pick-and-place device 6, aligning it with the clamped board and extending it between the board and the board feeding device 2. This allows the pick-and-place device 6 to stably pick up the board. Finally, the position angle adjustment device 7 adjusts the position and angle of the pick-and-place device 6 along with the board. The process involves adjusting the plate-picking and placing device 6 and the plate to the center position, then adjusting the angle of the plate (e.g., rotating the plate 180°). Simultaneously, the trolley or intelligent trolley transports the material box 1 to the material box positioning mechanism 5. The material box positioning mechanism 5 supports and positions the material box 1, and presses the box door 12 against the door opening and lifting device 8. The door opening and lifting device 8 opens and lifts the box door 12, aligning the plate with the box body 11 of the material box 1. The plate-picking and placing device 6 places the plate into the insertion slot 112 of the box body 11 to collect the plate. When the material box 1 is full of plates, the door opening and lifting device 8 closes the box door 12 at the opening of the box body 11. Finally, the material box positioning mechanism 5 releases its positioning of the material box 1, and the trolley or intelligent trolley can output the fully loaded material box 1. The present invention uses the tray rotation device 4 and the clamping mechanism 3 to work together to move the plate away from the plate feeding device 2 and adjust the placement angle of the plate, so as to facilitate the accurate and stable picking and placing of the plate by the plate picking and placing device 6, thereby improving the stability of plate picking and placing.

[0038] Specifically, there are multiple material box positioning mechanisms 5 and multiple door opening lifting devices 8, with each material box positioning mechanism 5 and door opening lifting device 8 corresponding to the other; preferably, there are two material box positioning mechanisms 5 and two door opening lifting devices 8. The two material box positioning mechanisms 5 are respectively paired with the two door opening lifting devices 8. This structural design facilitates the replacement of the material box 1, does not affect the efficiency of plate handling, and results in high plate handling efficiency.

[0039] In this embodiment, the plate feeding device 2 is equipped with an identification mechanism 9 and / or an edge-tracking positioning mechanism 91. The identification mechanism 9 and the edge-tracking positioning mechanism 91 are located on both sides of the clamping plate mechanism 3, and the edge-tracking positioning mechanism 91 is electrically connected to the position angle adjustment device 7. This automatic plate feeding and receiving machine also includes an electronic control system, and the identification mechanism 9 is electrically connected to the electronic control system.

[0040] After the pallet rotating device 4 adjusts the placement angle of the board, the identification mechanism 9 scans and identifies the markings (such as QR codes) on the board to obtain the board information, enabling the electronic control system to monitor the board. Additionally, after the pallet rotating device 4 adjusts the placement angle of the board, the edge-tracking positioning mechanism 91 tracks and positions the edge of the board to obtain its position, determine if there is any positional deviation, and specify the deviation value. The edge-tracking positioning result is then fed back to the position angle adjustment device 7, allowing the position angle adjustment device 7 to drive the board pick-and-place device 6 to pick up and place boards more stably and accurately.

[0041] Specifically, the edge-following positioning mechanism 91 includes an edge-following driver mounted on the board feeding device 2 and an edge-following sensor installed at the edge-following end of the edge-following driver; preferably, the edge-following driver can be a linear motor or the like. In practical applications, the edge-following driver is used to drive the edge-following sensor to move, so that the edge-following sensor can sense and position the edge of the board.

[0042] In this embodiment, the pallet rotating device 4 includes a lifting pallet mechanism 41 disposed below the pallet feeding device 2, a rotating mechanism 42 connected to the lifting pallet end of the lifting pallet mechanism 41, and a supporting rotating plate 43 connected to the rotating end of the rotating mechanism 42. The supporting rotating plate 43 can protrude through the pallet space 21 to above the pallet feeding surface of the pallet feeding device 2.

[0043] In practical applications, when the plate is located above the pallet space 21, the lifting pallet mechanism 41 drives the rotating mechanism 42 to rise along with the supporting rotating plate 43 and the plate, so that the plate is separated from the feeding surface of the feeding device 2. Then, the rotating mechanism 42 drives the supporting rotating plate 43 to rotate along with the plate by a preset angle (e.g., 90°) to adjust the placement angle of the plate. After adjustment, the clamping mechanism 3 clamps both sides of the plate.

[0044] Specifically, the clamping mechanism 3 includes two clamping modules 31, which are respectively mounted on both sides of the plate feeding device 2. The two clamping modules 31 clamp the two sides of the plate respectively, and can move closer or further apart to accommodate plates of different specifications. The height of the two clamping modules 31 is also adjustable. Preferably, the clamping modules 31 can be existing clamping units.

[0045] Specifically, multiple suction cups are embedded on the top surface of the rotating support plate 43; after the rotating support plate 43 supports the plate, the multiple suction cups firmly adhere the plate to the rotating support plate 43 to improve the stability of the plate.

[0046] In this embodiment, the plate picking and placing device 6 includes a support plate 61 connected to the adjustment end of the position angle adjustment device 7, a plurality of suction nozzles 62 embedded in the support surface of the support plate 61, a pressure plate module 63 installed on the support plate 61, and two guide limiting members 64 respectively installed on the support plate 61. The two guide limiting members 64 are arranged opposite to each other, and a plate space 65 is formed between the support surface of the support plate 61 and the two guide limiting members 64. The plurality of suction nozzles 62 are located in the plate space 65, and the pressure plate end of the pressure plate module 63 can protrude into the plate space 65.

[0047] In practical applications, when the board is located on the carrier space 65, the two ends of the board will abut against the two guide limiting members 64 respectively. Under the gravity of the board and the guiding action of the two guide limiting members 64, the board will stably enter the carrier space 65. The carrier plate 61 supports the board, and the two guide limiting members 64 abut against and limit the two ends of the board, improving the stability and positional accuracy of the board in the carrier space 65. Then, multiple suction nozzles 62 will suck the board in the carrier space 65 tightly onto the carrier plate 61. Finally, the pressure plate end of the pressure plate module 63 will protrude into the carrier space 65 and press the board tightly onto the carrier plate 61, ensuring the stability and positional accuracy of the board in the carrier space 65, so as to achieve stable board picking (board picking); conversely, the board release action (board release) can be completed. The plate pick-and-place device 6 has a simple structure and ingenious design. It guides and limits the position of the plate through two guiding and limiting components 64, and then clamps and presses the plate within the carrier space 65, which greatly improves the positional accuracy and stability of the plate pick-and-place device.

[0048] Specifically, the spacing between the two guiding and limiting components 64 is adjustable to meet the needs of guiding and limiting plates of different specifications. Specifically, the guiding and limiting block 66 has an L-shaped cross-section. The horizontal section of the guiding and limiting block 66 is embedded in the supporting plate 61, and the top of the vertical section of the guiding and limiting block 66 is provided with an inner guide slope, which is inclined towards the carrying plate space 65. In practical applications, when the end edge of the plate abuts against the inner guide slope, under the action of the plate's gravity, the plate will slide along the inner guide slope into the carrying plate space 65 until the plate completely falls into the carrying plate space 65. Then, the inner vertical surface of the vertical section of the guiding and limiting block 66 will limit the end edge of the plate, thereby achieving guiding, correcting, and limiting of the plate.

[0049] Specifically, two adjacent suction nozzles 62 are connected via an air tube, which facilitates the connection of multiple suction nozzles 62; preferably, at least one suction nozzle 62 is connected to an external vacuum mechanism, so that one external vacuum mechanism can generate negative pressure in all suction nozzles 62.

[0050] Specifically, the support plate 61 is provided with multiple conduit slots 67, and the trachea is housed in the corresponding conduit slots 67. This structural design makes the structure of the trachea and the support plate 61 compact, effectively hiding and protecting the trachea, managing the trachea, and resulting in a neat and aesthetically pleasing appearance, avoiding the trachea from being exposed and affecting normal plate placement and removal, as well as the overall appearance.

[0051] In this embodiment, the position angle adjustment device 7 includes a horizontal movement drive mechanism 71, a first vertical movement drive mechanism 72, an angle adjustment mechanism 73, a second vertical movement drive mechanism 74, and two oppositely arranged pick-and-place plate lifting mechanisms 75. One end of the horizontal movement drive mechanism 71 is fixedly connected to the lifting end of one pick-and-place plate lifting mechanism 75, and the other end of the horizontal movement drive mechanism 71 is flexibly connected to the lifting end of the other pick-and-place plate lifting mechanism 75. The first vertical movement drive mechanism 72 is connected to the horizontal movement end of the horizontal movement drive mechanism 71, the angle adjustment mechanism 73 is connected to the vertical movement end of the first vertical movement drive mechanism 72, the second vertical movement drive mechanism 74 is connected to the adjustment end of the angle adjustment mechanism 73, and the pick-and-place plate device 6 is connected to the vertical movement end of the second vertical movement drive mechanism 74.

[0052] In practical applications, the two pick-and-place plate lifting mechanisms 75 work synchronously to drive the pick-and-place plate device 6 to adjust its height; the transverse drive mechanism 71 drives the pick-and-place plate device 6 to adjust its transverse position so that the pick-and-place plate device 6 can switch positions between multiple material boxes 1; the first longitudinal drive mechanism 72 and the second longitudinal drive mechanism 74 cooperate to drive the pick-and-place plate device 6 to move longitudinally. By adopting the configuration of the first longitudinal drive mechanism 72 and the second longitudinal drive mechanism 74, the volume of a single longitudinal drive mechanism is shortened while ensuring the longitudinal movement stroke. Because one end of the transverse drive mechanism 71 is flexibly connected to the lifting end of one of the pick-and-place lifting mechanisms 75, when the lifting heights of the two pick-and-place lifting mechanisms 75 are inconsistent due to errors (such as installation errors, processing errors, control errors, etc.), one end of the transverse drive mechanism 71 can swing relative to the lifting end of one of the pick-and-place lifting mechanisms 75. This avoids hard impacts or squeezing between the transverse drive mechanism 71 and the two pick-and-place lifting mechanisms 75, thus protecting the pick-and-place lifting mechanism and extending its service life.

[0053] In this embodiment, the material bin 1 includes a box body 11, a box door 12 for covering the opening of the box body 11, a door lock mechanism 13 disposed inside the box door 12 for locking or unlocking the box door 12 and the box body 11, and two pressure plate mechanisms 14 respectively disposed in the two side plates of the box body 11. Two pressure plate control mechanisms 15 are respectively disposed on the upper sides of the material bin positioning mechanism 5, and the two pressure plate control mechanisms 15 are respectively disposed in a one-to-one correspondence with the two pressure plate mechanisms 14. A row of insert plate groups 111 is disposed on the inner wall of each side plate of the box body 11, and the two pressure plate mechanisms 14 are respectively disposed in a one-to-one correspondence with the two rows of insert plate groups 111. Each pressure plate control mechanism 15 is used to apply pressure to the pressure plate operating end of the corresponding pressure plate mechanism 14. The material bin positioning mechanism 5 is used to position the box body 11. Specifically, the pressure plate control mechanism 15 includes a cylinder and a control plate. The cylinder is used to drive the control plate to rise and fall, and the control plate is used to apply pressure to the pressure plate operating end of the pressure plate mechanism 14.

[0054] In this embodiment, each row of insert plate groups 111 includes multiple insert plate slots 112, and the insert plate slots 112 on the two rows of insert plate groups 111 are arranged one-to-one. The pressing plate mechanism 14 includes a base 141 installed in the side plate of the housing 11, a slide plate 142 slidably connected to the base 141, a guide rod frame 143 slidably connected to the base 141 and / or the housing 11, an operating member 144 installed at the top of the guide rod frame 143 and located outside the housing 11, a swing arm 145 with one end hinged to the bottom of the base 141, a locking block 146 connected to the other end of the swing arm 145, a connector 147 with one end installed on the slide plate 142, a mounting plate 148 connected to the other end of the connector 147, and a mounting plate 148 installed on the mounting plate. Multiple pressing plates 149 of 148 are fixedly connected to the bottom end of the guide rod frame 143 and the slide plate 142. The guide rod frame 143 is covered with an elastic element 140. The two ends of the elastic element 140 are elastically connected to the slide plate 142 and the base 141, respectively. The multiple pressing plates 149 are respectively arranged in a corresponding manner to the multiple insertion slots 112 of the insertion plate assembly 111. The side of the slide plate 142 is recessed with a cam groove 1421. The cam groove 1421 has a pressing position 1422 and an opening position 1423. The locking block 146 protrudes into the cam groove 1421. The locking block 146 can be locked in the pressing position 1422 or the opening position 1423. The pressure plate control mechanism 15 is used to apply pressure to the operating member 144. The elastic element 140 is a spring.

[0055] In practical applications, the door 12 covers the opening of the box body 11, and the door lock mechanism 13 locks the door 12 onto the box body 11. When it is necessary to take or put away a panel inside the box body 11, the door lock mechanism 13 unlocks the door 12 from the box body 11, allowing the door 12 to open the box body 11. When the box body 11 is unloaded, under the elastic force of the elastic element 140, the locking block 146 engages with the opening position 1423 of the cam groove 1421, so that the pressing plate 149 is in the open state. At this time, the panel can be inserted into the insertion slot 112 of the two rows of insert plate groups 111. After the panel is retracted, the pressure plate control mechanism 15 applies a downward force (pressure) to the operating element 144, so that the guide rod frame 143, along with the sliding plate 142 and the connecting element 149, can be engaged. 47. The mounting plate 148 and multiple pressing plates 149 slide downwards. As the slide plate 142 moves downwards along the base 141, the locking block 146 will first disengage from the open position 1423, the swing arm 145 swings, and the locking block 146 moves along the trajectory of the cam groove 1421 until the locking block 146 moves to the pressing position 1422. Under the elastic force of the elastic element 140, the locking block 146 is locked at the pressing position 1422. At this time, the multiple pressing plates 149 press the plate onto the bottom wall of the corresponding insert groove 112. The multiple pressing plates 149 are in the pressing state, and the door lock mechanism 13 locks the box door 12 onto the box body 11 to encapsulate the plate inside the box body 11, which facilitates the loading and transportation of the plate by this material box 1. When the plate needs to be removed, the pressure plate control mechanism 15 applies a downward force to the operating member 144 again, causing the locking block 146 to disengage from the pressing position 1422. The swing arm 145 swings, and the locking block 146 moves along the trajectory of the cam groove 1421 until it moves to the open position 1423. Under the elastic force of the elastic member 140, the locking block 146 is locked in the open position 1423, and the multiple pressing plates 149 are in the open state. At this time, the plate can be removed from the housing 11. Since the operating member 144 is exposed outside the housing 11, it is easy to switch the working state of the pressing plates 149 (open or pressing state). The plate is pressed tightly inside the housing 11 by the pressure plate mechanism 14, which improves the stability of loading and transporting the plate. The operation of the pressure plate mechanism 14 is stable and easy to switch the working state of the pressure plate mechanism 14, making the operation convenient.

[0056] In this embodiment, the door opening and lifting device 8 includes a frame 81, a suction plate 82 disposed on the frame 81, a key 83 rotatably connected to one side of the suction plate 82, an unlocking drive module 84 disposed on the other side of the suction plate 82 and used to drive the key 83 to rotate, an opening and closing moving mechanism 85 disposed on the frame 81 and used to drive the suction plate 82 to approach or move away from the material box 1, a door opening and lifting mechanism 86 drivenly connected to the frame 81, and a pressing mechanism 87 disposed on the side of the suction plate 82 near the material box 1 and used to press the box body 11. The box door 12 has an insertion hole 122 corresponding to the door lock mechanism 13. After the key 83 is inserted into the insertion hole 122, it is drivenly connected to the door lock mechanism 13. The suction plate 82 is fitted with a plurality of suction plates 88, which are used to press the box door 12.

[0057] In practical applications, a trolley or intelligent vehicle transports the bin 1 to the bin positioning mechanism 5. The bin positioning mechanism 5 positions the bin 1 so that the bin door 12 is pressed against the suction plate 82, and the pressing mechanism 87 presses the bin body 11 to ensure the positional accuracy and stability of the bin body 11. After the key 83 is inserted into the jack 122, it is driven to connect with the door lock mechanism 13. The unlocking drive module 84 drives the key 83 to rotate. The rotating key 83 turns the door lock mechanism 13, causing the door lock mechanism 13 to unlock the bin door 12 and the bin body 11. Then, the opening and closing moving mechanism 85 drives the suction plate 82 and the bin door 12 to move away from the bin body 11, so that the bin door 12 opens the bin body 11. Then, the door opening lifting mechanism 86 drives the frame 81 and the suction plate 82 and the bin door 12 to rise, so as to expose the bin opening of the bin body 11, thereby facilitating the plate picking and placing device 6 to pick up and place plates from the bin body 11.

[0058] In this embodiment, the door lock mechanism 13 includes a gear 131 rotatably connected to the box door 12 and a lock block 132 slidably connected to the box door 12. The linkage end of the lock block 132 is provided with a rack 133 that meshes with the gear 131. A through hole 121 is provided on the side frame of the box door 12. The lock tongue of the lock block 132 can protrude to the outside of the box door 12 through the through hole 121. A non-circular screw hole 134 is recessed in the middle of the gear 131. The screw hole 134 is correspondingly connected to the insertion hole 122. A locking hole correspondingly connected to the through hole 121 is provided at the box opening of the box body 11.

[0059] When the door 12 closes the box body 11, the locking hole of the box body 11 and the through hole 121 of the door 12 are connected one-to-one. When it is necessary to lock the door 12 onto the box body 11, the key 83 is inserted into the turning hole 134 through the insertion hole 122 and the key 83 is turned clockwise, so that the key 83 drives the gear 131 to rotate clockwise. The clockwise rotating gear 131 meshes with the rack 133 of the lock block 132 to drive the lock block 132 to move outward, so that the lock block 132 protrudes out of the door 12 through the through hole 121 and is inserted into the locking hole, so as to lock the door 12 onto the box body 11. When it is necessary to unlock the door 12, simply turn the key 83 in the opposite direction, so that the lock block 132 moves away from the locking hole and retracts into the through hole 121, so as to unlock the door 12. The suction plate 82 pulls the door 12 outward from the box body 11 to open the box body 11. This structural design ensures that the outer surface of the door 12 is flat, and the lock block 132 is driven to reciprocate through the meshing of gear 131 and rack 133, which ensures reliable transmission and convenient operation.

[0060] Specifically, there are multiple door lock mechanisms 13, each corresponding to one key 83, and each unlocking drive module 84 drives two keys 83 to rotate synchronously. By using multiple door lock mechanisms 13 to lock the cabinet door 12 onto the cabinet body 11, the stability and robustness of the locked door 12 are improved. Preferably, there are four door lock mechanisms 13 and four keys 83, and two unlocking drive modules 84. The unlocking drive modules 84 can adopt a cylinder-driven linkage structure to drive the two keys 83 to rotate synchronously. The four door lock mechanisms 13 are arranged in a rectangular array, and adjacent door lock mechanisms 13 are symmetrically arranged. Each door lock mechanism 13 preferably has two locking blocks 132, which are vertically arranged.

[0061] In this embodiment, each door lock mechanism 13 has 1-4 lock blocks 132, and the rack 133 on each lock block 132 meshes with the gear 131. The latch of each lock block 132 corresponds to a through hole 121.

[0062] When each door lock mechanism 13 has two locking blocks 132, one gear 131 drives the two locking blocks 132 to reciprocate in different directions. The two locking blocks 132 can be arranged parallel or at an angle. When the two locking blocks 132 are arranged parallel, their movement directions are opposite. When the two locking blocks 132 are arranged at an angle, they are preferably arranged perpendicularly. This structural design achieves a one-to-two mechanism (one gear 131 drives two locking blocks 132 to move).

[0063] When each door lock mechanism 13 has three locking blocks 132, one locking block 132 is perpendicular to the other two locking blocks 132, and the other two locking blocks 132 are parallel and move in opposite directions, with the three locking blocks 132 roughly forming a U-shape. This structural design achieves one-to-three (one gear 131 drives the movement of three locking blocks 132).

[0064] When each door lock mechanism 13 has four locking blocks 132, the four locking blocks 132 roughly form a cross shape. This structure is designed to achieve one-to-four (one gear 131 drives four locking blocks 132 to move).

[0065] In this embodiment, the side wall of the lock block 132 is recessed with a locking position 135 and an unlocking position 136, and a locking mechanism 123 is installed inside the door 12. When the locking end of the locking mechanism 123 engages with the locking position 135, the bolt of the lock block 132 extends out of the door 12 and locks the door 12 onto the box body 11. When the locking end of the locking mechanism 123 engages with the unlocking position 136, the bolt of the lock block 132 retracts into the through hole 121, and the door 12 is unlocked from the box body 11. This structural design improves the stability of the lock block 132 in both the unlocked and locked states.

[0066] Specifically, the latching mechanism 123 includes a spring ball, the spring ball of which can extend into the locking position 135 or the unlocking position 136; it has a simple structure, low cost, and good working stability.

[0067] Specifically, a guide post 1471 is slidably connected to the end of the connector 147 away from the slide plate 142. A limiting ring 1472 is installed at one end of the guide post 1471, which abuts against one end face of the connector 147. The other end of the guide post 1471 is fixedly connected to the lug of the mounting plate 148. A buffer spring 1473 is fitted over the guide post 1471, and both ends of the buffer spring 1473 elastically abut against the other end face of the connector 147 and the lug of the mounting plate 148, respectively. During the pressing process of the pressing plate 149, the buffer spring 1473 plays a buffering role, preventing the pressing plate 149 from applying excessive pressure to the circuit board and damaging it.

[0068] Specifically, the interior of the housing 11 has multiple support rods 116, each corresponding to a different insertion slot 112. The support rods 116 support the bottom surface of the plate to support the middle of the plate and prevent it from bending and deforming downwards.

[0069] Specifically, the bottom surface of the box 11 is provided with several support blocks 115 and several positioning blocks 114. The material box positioning mechanism 5 includes a translation drive mechanism 51 located on the side of the door lifting device 8 away from the pick-and-place plate device 6, a moving plate 52 connected to the moving end of the translation drive mechanism 51, a locking clamp 53 located on the moving plate 52, and several centering floating units 54 connected to the moving plate 52. The locking clamp 53 is used to lock the positioning blocks 114, the centering floating units 54 are used to support the bottom surface of the box 11, and the support blocks 115 are used to abut against the moving plate 52.

[0070] In practical applications, a trolley or intelligent vehicle transports the material box 1 onto the moving plate 52. The support block 115 of the box body 11 abuts against the moving plate 52. Multiple centering floating units 54 abut against and support the bottom surface of the box body 11. The locking clamp 53 locks the positioning block 114 on the bottom surface of the box body 11. During the locking process of the box body 11, the box body 11 can be adjusted relative to the moving plate 52 by the centering floating unit 54. After the locking clamp 53 locks the box body 11, gas is introduced into the centering floating unit 54 to lock the centering floating unit 54, so as to realize the position correction and positioning of the material box 1. Then, the translation drive mechanism 51 drives the moving plate 52 and the material box 1 to move to the suction door plate 82.

[0071] Preferably, the bin positioning mechanism 5 further includes a lifting drive module (not shown in the figure), the lifting end of which is connected to the translation drive mechanism 51. When the trolley or smart car does not have a lifting function, the lifting drive module drives the translation drive mechanism 51 to rise, so that the moving plate 52 can detach the bin 1 from the trolley or smart car to realize the transfer of the bin 1, or the lifting drive module drives the moving plate 52 to descend, so as to place the bin 1 on the trolley or smart car.

[0072] Specifically, the bin positioning mechanism 5 also includes a locking mechanism 55 located below and on the front side of the translation drive mechanism 51. When the trolley or smart car is delivered to its position, the locking mechanism 55 locks the trolley or smart car to secure its position, thereby improving the positioning accuracy and stability of the trolley or smart car.

[0073] Specifically, each insert slot 112 has an opening and closing groove 113 on its side wall for raising and lowering the pressing plate 149. The opening and closing groove 113 provides space for the pressing plate 149 to move up and down (raise and lower), making the pressing plate 149 and the housing 11 structurally compact.

[0074] Specifically, the discharge end of the plate feeding device 2 is provided with a front baffle 22. When the plate feeding device 2 conveys the plate to the point where it comes into contact with the front baffle 22, the front baffle 22 blocks and limits the plate to prevent the plate from being over-conveyed and improves the stability of the conveyed plate.

[0075] Specifically, the plate feeding mechanism includes a conveyor frame 23, multiple conveyor rollers 24 parallel and rotatably connected to the conveyor frame 23, two sets of guide conveyor groups 25 parallelly arranged within the conveyor frame 23, and a conveying rotation drive mechanism 26 arranged on the conveyor frame 23 for driving the rotation of all the conveyor rollers 24. The pallet space 21 is located between two adjacent conveyor rollers 24, and the rotating plate 43 is located between the two sets of guide conveyor groups 25. In practical applications, the conveying rotation drive mechanism 26 drives the multiple conveyor rollers 24 to rotate synchronously. The rotating multiple conveyor rollers 24 drive the plate to move along the two sets of guide conveyor groups 25 to achieve stable conveying of the plate.

[0076] In this embodiment, the guide conveying group 25 includes multiple guide wheels 251, each guide wheel 251 being rotatably disposed between two adjacent conveying rollers 24. During the process of the multiple conveying rollers 24 conveying the plate, the two sides of the plate roll and abut against the multiple guide wheels 251 of the two guide conveying groups 25 respectively. The guide wheels 251 not only limit the left and right positions of the plate, but also guide the movement of the plate, thereby improving the movement stability and positional accuracy of the plate.

[0077] Specifically, the guide conveyor group 25 also includes an adjustment plate (not shown in the figure). Multiple guide wheels 251 are rotatably connected to the adjustment plate, which is located on the conveyor frame 23 and below the multiple conveyor rollers 24. The adjustment plate can be adjusted relative to the conveyor frame 23. The adjustment plate facilitates the installation of the multiple guide wheels 251, and by adjusting the relative position between the adjustment plate and the conveyor frame 23, it is also easy to adjust the spacing between the two guide conveyor groups 25 to meet the needs of guiding and limiting the conveying of plates of different widths.

[0078] Specifically, each conveyor roller 24 is equipped with at least two conveyor wheels 241. In practical applications, the conveyor wheels 241 abut against the accessible parts of the plate to support and convey the plate, while the non-accessible parts of the plate are hollowed out to prevent damage to the plate during conveying.

[0079] Specifically, the conveying rotation drive mechanism 26 includes a rotation driver mounted on the conveyor frame 23, a rotating shaft rotatably connected to the conveyor frame 23, multiple first magnetic rings fitted onto the rotating shaft, and multiple second magnetic rings respectively fitted onto the ends of multiple conveying rollers 24. The multiple first magnetic rings are respectively and one-to-one corresponding to the multiple second magnetic rings and are driven connected. The rotation drive end of the rotation driver is driven connected to the rotating shaft, and the central axis of the first magnetic ring is perpendicular to the central axis of the second magnetic ring. Preferably, the rotation driver can use a structure of a motor driving a synchronous pulley and a synchronous belt for transmission. In practical applications, the rotation driver drives the rotating shaft to rotate, and the rotating shaft drives the multiple first magnetic rings to rotate. Under the magnetic force of the first and second magnetic rings, the rotating first magnetic rings drive the second magnetic rings to rotate, and the rotating second magnetic rings drive the conveying rollers 24 to rotate. The rotating conveying rollers 24 move the plates to achieve the conveying of the plates. Magnetic transmission through the first and second magnetic rings avoids the dander generated by belt transmission, preventing contamination of the plates.

[0080] Specifically, the rotating support plate 43 has clearance holes for avoiding the conveyor wheel 241, and guide blocks are provided on both sides of the rotating support plate 43. When the rotating support plate 43 lifts the plate, the guide blocks abut against the sides of the plate to guide the plate's position on the rotating support plate 43 until the rotating support plate 43 stably supports the plate. The guide blocks limit the sides of the plate. The structure of the guide blocks is the same as that of the guide limiting block 66, and will not be described again here.

[0081] Specifically, a positioning post 89 is provided on the side of the suction door plate 82 near the material box 1, and a positioning hole is recessed in the box door 12. The positioning post 89 and the positioning hole are adapted to each other. By cooperating with the positioning post 89 and the positioning hole, the positional accuracy and stability of the suction door plate 82 and the box door 12 are improved.

[0082] All technical features in this embodiment can be freely combined according to actual needs.

[0083] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
