[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like Figures 1 to 3 As shown, the utility model is a contactless plate forming machine, comprising a box conveying line 1, a plate conveying line 2, a transverse movement mechanism 3, and a suction cup mechanism 4. The box conveying line 1 and the plate conveying line 2 are aligned, the transverse movement mechanism 3 spans between the box conveying line 1 and the plate conveying line 2, the suction cup mechanism 4 is connected to the transverse movement mechanism 3, the suction cup mechanism 4 comprises a plurality of buffer rods 41 and a contactless suction nozzle 42, the top end of the buffer rod 41 is externally connected to an air supply source, and the bottom end of the buffer rod 41 is connected to the contactless suction nozzle 42.

[0031] Box conveying line 1 is used for loading empty boxes 16 and unloading full boxes 16. Empty boxes 16 are transported to the loading end of box conveying line 1 by cart 14. The unloading end is also connected to cart 15. When box 16 is filled with sheet materials, it will be sent to cart 15 for transportation to the next process. Sheet material conveying line 2 is used for loading and unloading of sheet materials. Sheets include circuit substrates, paperboards, panels, and PP cover sheets. After the sheet materials are transported to the designated position, the circuit substrates will be removed from the PIN, and the lateral movement mechanism 3 will drive the suction cup mechanism 4 to grab the circuit substrate and place it in the empty box 16 to complete the unloading operation.

[0032] like Figures 4 to 6 As shown, a nozzle air inlet hole 421 is provided on the top of the contactless suction nozzle 42, and an annular air outlet groove 422 is provided on the bottom of the contactless suction nozzle 42. The nozzle air inlet hole 421 is connected to the buffer rod 41, and the nozzle air inlet hole 421 is communicated with the annular air outlet groove 422. The gas is discharged laterally along the annular air outlet groove 422 and forms an air cushion on the outer circle of the bottom of the contactless suction nozzle 42, and the central area of ​​the annular air outlet groove 422 forms a vacuum adsorption area.

[0033] The contactless suction nozzle 42 realizes contactless plate removal through the cyclone generated by the suction nozzle. The external compressed air passes through the buffer rod 41 and enters the suction nozzle air inlet 421. The structure of the annular air outlet groove 422 is used to discharge the compressed air along the annular air outlet groove 422 to the outer circumferential area at the bottom of the contactless suction nozzle 42, so that a high-pressure air cushion area is formed in the outer circumferential area, and an air barrier is constructed between the sheet and the contactless suction nozzle 42 to prevent the contactless suction nozzle 42 from directly contacting the sheet. At the same time, since the contactless suction nozzle 42 has no gas discharged in the central area of ​​the annular air outlet groove 422, the central area naturally forms a low-pressure center relative to the high pressure of the periphery. The external air will flow to the central area to form a suction area. This principle is used to adsorb the sheet at the bottom of the contactless suction nozzle 42, thereby achieving the effect of contactless adsorption.

[0034] The suction cup mechanism 4 of the present forming plate unloading machine adopts a contactless suction nozzle 42, which can realize contactless plate removal through the cyclone generated by the suction nozzle when sucking the plate, thereby preventing the formed plate from being scratched or damaged due to contact.

[0035] like Figures 7 to 9 As shown, the buffer rod 41 includes a buffer shell 411, a hollow ventilation rod 412, a spring 413, a limiting column 414, and an adapter 415. The ventilation rod 412 is movably connected in the buffer shell 411. One end of the spring 413 is connected to the ventilation rod 412, and the other end is connected to the buffer shell 411. A strip groove 416 is provided on the ventilation rod 412. The limiting column 414 is connected to the buffer shell 411 and inserted into the strip groove 416. The bottom of the ventilation rod 412 is connected to the contactless suction nozzle 42 through the adapter 415, and the top of the ventilation rod 412 is connected to the external air supply source through the buffer shell 411.

[0036] The buffer rod 41 adopts a spring 413 structure, and the pressure during the descent process is buffered to a certain extent. When descending, the pressure received by the non-contact suction cup will be transmitted to the buffer rod 41, and the pressure will compress the spring 413. At this time, the ventilation rod 412 will retract upward, and synchronously drive the strip groove 416 to move upward along the limit column 414. However, when the pressure is reduced or disappears, the spring 413 will push the ventilation rod 412 downward again, and the cooperation of the limit column 414 and the strip groove 416 limits the maximum distance of the ventilation rod 412 to descend.

[0037] The suction cup mechanism 4 also includes a suction cup bracket 43, which is provided with multiple branches for respectively connecting multiple buffer rods 41. The buffer rod 41 is fixed to the suction cup bracket 43 through a buffer shell 411 and a fastener 417. Each buffer rod 41 is connected to a contactless suction nozzle 42 through an adapter 415. Multiple contactless suction nozzles 42 together form a contactless adsorption surface for adsorbing sheet materials.

[0038] like Figure 1 and Figure 2 As shown, the sheet material conveying assembly line 2 includes a positioning, conveying, lifting and removing PIN mechanism 5 and a sheet material lifting and conveying mechanism 6. Both ends of the loading and unloading stations of the positioning, conveying, lifting and removing PIN mechanism 5 are connected with a sheet material lifting and conveying mechanism 6, and the transverse movement mechanism 3 spans between the positioning, conveying, lifting and removing PIN mechanism 5 and the box conveying assembly line 1.

[0039] The loading and unloading of the sheet material can be operated by a trolley, that is, the entire sheet material conveying line 2 is sequentially composed of a loading trolley 21, a sheet material lifting and conveying mechanism 6 at the loading end, a positioning and conveying lifting and PIN removal mechanism 5, a sheet material lifting and conveying mechanism 6 at the unloading end, and an unloading trolley 22. Since there is a certain height difference between the trolley and the positioning and conveying lifting and PIN removal mechanism 5, the height transition needs to be completed by the sheet material lifting and conveying mechanism 6. The positioning and conveying lifting and PIN removal mechanism 5 is used to remove the PIN pins of the circuit substrate, and then the multiple circuit substrates after PIN removal are transported to the box 16 of the box conveying line 1 through the traverse mechanism 3 and the suction cup mechanism 4.

[0040] like Fig.10 As shown, the positioning, conveying, lifting and removing PIN mechanism 5 includes a PIN removing platform 51, a top corner positioning block 54, a lifting assembly 52, a plate conveying assembly 53, and a flexible pressure plate assembly 56. The plate conveying assembly 53 is connected to the plate lifting and conveying mechanism 6 and carries the plate. The plate conveying assembly 53 is provided with a PIN removing station. The PIN removing platform 51 is located below the PIN removing station. The top corner positioning block 54 is arranged at multiple top corners of the PIN removing station. The lifting assembly 52 is connected to the PIN removing platform 51. When removing the PIN, the lifting assembly 52 drives the PIN removing platform 51 to rise and contact with the plate; the flexible pressure plate assembly 56 is arranged on the side of the PIN removing station. When removing the PIN, the flexible pressure plate assembly 56 presses the edge of the plate.

[0041] like Fig.11 As shown, the PIN removal operation on the PIN removal platform 51 refers to the process of removing the circuit substrate from the pin 55. The four corners of the PIN removal platform 51 are provided with corner positioning blocks 54, and the four corner positioning ensures that the sheet material reaches the board removal position accurately. On the positioning, conveying, lifting and PIN removal mechanism 5, when the sheet material is conveyed to the board removal position, the cylinder drives the corner positioning blocks 54 to position the four corners of the sheet material, ensuring that the sheet material reaches the board removal position accurately.

[0042] A plate conveying assembly 53 is provided on each side of the PIN removal station. A plurality of flexible pressure plate assemblies 56 are fixed side by side on the frame of each plate conveying assembly 53, and are aligned with the edges of the plate materials on the PIN removal station. The flexible pressure plate assembly 56 includes a flexible pressure plate cylinder 561 and a flexible pressure plate rod 562. The cylinder body of the flexible pressure plate cylinder 561 is fixedly connected to the frame of the plate conveying assembly 53. The output shaft of the flexible pressure plate cylinder 561 is connected to the flexible pressure plate rod 562. The flexible pressure plate rod 562 can be controlled to rise or press down by the extension and contraction of the flexible pressure plate cylinder 561. When removing the PIN, the flexible pressure plate cylinder 561 retracts, and the flexible pressure plate rod 562 descends to press the edge of the plate material to prevent the edge of the plate material from warping up. After the PIN removal is completed, the flexible pressure plate cylinder 561 extends when removing the PIN, so that the flexible pressure plate rod 562 is separated from the plate material.

[0043] The lifting assembly 52 is combined with the PIN removal platform 51, and is lifted and lowered under the plate conveying assembly 53, and at the same time, the flexible pressing plate assembly 56 is pressed down to prevent the cardboard, circuit substrate and PP cover from being tilted and shifted due to uneven force at the four corners during the PIN removal process, so that the cardboard, circuit substrate and PP cover can be separated from the electric board smoothly. The flexible pressing plate assembly 56 and the lifting assembly 52 cooperate to solve the problem of difficulty in PIN removal of existing models and damage to the plate during the PIN removal process.

[0044] The lifting assembly 52 can adopt a linkage structure in which a motor 521 drives multiple screw rods 522. The multiple screw rods 522 respectively support different fulcrums of the column PIN removal platform 51, and the screw rods 522 convert the rotational motion into linear motion to complete the lifting and lowering of the PIN removal platform 51. The plate conveying assembly 53 can adopt a structure of two rows of conveyor belts, and a motor synchronously controls the two rows of conveyor belts to achieve the transmission effect. There is also space between the two rows of conveyor belts, which provides space for the lifting and lowering movement of the PIN removal platform 51, so that the PIN removal platform 51 can contact the material plate on the conveyor belt.

[0045] A CCD camera is also used on the positioning, conveying, lifting and removing PIN mechanism 5 to take pictures. Combined with the image analysis system, it is determined whether the suction cup mechanism 4 has successfully taken the board and whether the product is stacked, and an alarm is issued in time to remind the staff to deal with it in time to reduce the chance of scrapping the board.

[0046] like Fig.12As shown, the sheet material lifting and conveying mechanism 6 includes a lifting motor module 61, a lifting bracket 62, a lifting and conveying assembly 63, and a dust collecting assembly 64. The lifting bracket 62 is movably connected to the lifting motor module 61, the lifting and conveying assembly 63 is fixedly connected to the lifting bracket 62, and the dust collecting assembly 64 is arranged above the lifting and conveying assembly 63. The lifting motor module 61 includes a servo motor 611 and an elevator 612. The lifting bracket 62 is fixed on the elevator 612. The servo motor 611 drives the elevator 612 to move up and down, thereby driving the lifting and conveying assembly 63 on the lifting bracket 62 to move up and down together, so that the lifting and conveying assembly 63 can correspond to the plates of different heights on the sheet material cart; the servo motor 611 is then used to make the lifting and conveying assembly 63 accurately dock with the PIN removal platform 51; the lifting and conveying assembly 63 includes a conveying motor 631 and a conveyor belt 632. The conveying motor 631 drives the conveyor belt 632 to move, thereby driving the movement of the sheet material. The dust suction component 64 is aimed at the plate material on the lifting and conveying component 63 to suck away the fine floating dust on the surface of the circuit substrate.

[0047] The present forming and unloading machine conveys the plate through the plate lifting and conveying assembly 63, which solves the problem that the conveyor belt can only convey circuit substrates of fixed height. At the same time, a dust collecting assembly 64 is provided on the conveyor belt at the entrance and exit, and the fine floating dust on the surface of the circuit substrate will be sucked away before it is conveyed into the equipment, so as to keep the surface of the plate clean. The plate lifting and conveying mechanism 6 is a combination of the lifting motor module 61, the lifting and conveying assembly 63 and the dust collecting assembly 64, which reduces the complexity of the structure and reduces the space occupied by the machine.

[0048] like Fig.13 As shown, the box conveying line 1 includes a box conveying mechanism 11, which includes a box conveying frame 12 and an in-place sensor 13. The box conveying frame 12 is provided with a box loading station, the lateral movement mechanism 3 spans the box loading station, and the in-place sensor 13 is connected to the box conveying frame 12 and aligned with the box loading station. The box conveying frame 12 is docked with a cart for loading and unloading boxes. The empty box 16 of the cart 14 at the loading end is conveyed to the box conveying frame 12, and the in-place sensor 13 is used to determine whether the empty material box 16 has reached the board placement position. If the empty material box 16 is in place, the lateral movement mechanism 3 and the suction cup mechanism 4 start to perform the operation of carrying the sheet material, and when the box 16 is full, it is conveyed to the cart 15 at the unloading end.

[0049] like Fig.14As shown, the lateral movement mechanism 3 includes a lateral movement module 31, a vertical module 32, and a suction cup fixing head 33. The lateral movement module 31 spans across the box conveying line 1 and the sheet conveying line 2. The vertical module 32 is movably connected to the lateral movement module 31. The suction cup fixing head 33 is movably connected to the vertical module 32. The suction cup mechanism 4 is connected to the suction cup fixing head 33. The lateral movement module 31 controls the suction cup mechanism 4 to perform lateral movement, the vertical module 32 controls the suction cup to perform up and down movement of picking up and placing the plate, and the suction cup fixing head 33 is used to install the non-contact suction cup mechanism 4. The cooperation between the various components drives the suction cup mechanism 4 to carry out the transportation operation between various stations.

[0050] like Figure 1 and Figure 2 As shown, the non-contact board forming machine also includes a paper separator feed drawer 7, which is placed on one side of the box conveying line 1. Two groups of suction cup mechanisms 4 are connected to the transverse mechanism 3, one group of suction cup mechanisms 4 moves between the paper separator feed drawer 7 and the box conveying line 1 to load the paper separator, and the other group of suction cup mechanisms 4 moves between the sheet material conveying line 2 and the box conveying line 1 to load the sheet material. The two groups of suction cup mechanisms 4 move alternately. When placing circuit substrates, each layer of circuit substrates needs to be separated by paper separators to prevent adjacent layers of circuit substrates from contacting each other. The paper separator feed drawer 7 is placed with paper separators. After one group of suction cup mechanisms 4 places a layer of circuit substrates in the box 16, the other group of suction cup mechanisms 4 will grab the partition and cover the layer of circuit substrates, and then carry the next layer of circuit substrates.

[0051] like Figure 1 and Figure 2 As shown, the non-contact plate forming unloading machine also includes a sampling inspection platform 8, which is located on one side of the plate conveying line 2 and within the range of the transverse movement mechanism 3. The transverse movement mechanism 3 drives the suction cup mechanism 4 to move between the plate conveying line 2 and the sampling inspection platform 8. When the quality of the plate needs to be inspected, the plate to be inspected can be grabbed by the suction cup mechanism 4 and placed on the sampling inspection platform 8 for inspection. The transverse movement mechanism 3 spans above the sampling inspection platform 8, making it convenient for the suction cup mechanism 4 to grab the plate on the plate conveying line 2 and send it to the sampling inspection platform 8.

[0052] The non-contact board forming unloading machine also includes a waste PP cover sheet discharging drawer 9, which is located on one side of the board conveying line 2 and within the range of the transverse movement mechanism 3. The transverse movement mechanism 3 drives the suction cup mechanism 4 to move between the board conveying line 2 and the waste PP cover sheet discharging drawer 9. Some boards are covered with PP cover sheets when they are transported. Before taking the circuit substrate, the PP cover sheets on the circuit substrate need to be removed by the suction cup mechanism 4 and transported to the waste PP cover sheet discharging drawer 9 for unified recycling.

[0053] The forming plate unloading machine of the utility model is composed of a transverse movement mechanism 3, a contactless suction cup mechanism 4, a plate lifting and conveying mechanism 6, a box conveying mechanism 11, and a positioning conveying lifting and PIN-removing platform 51, and the plates are unloaded through the cooperation of these mechanisms.

[0054] The following is the working process of the forming machine:

[0055] S1. When the cart 14 carrying the empty material box 16 arrives at the designated position and docks with the box conveying mechanism 11; the feeding plate cart 21 docks with the plate lifting and conveying mechanism 6 at the loading end.

[0056] S2. The empty material box 16 enters the box conveying frame 12 of the box conveying mechanism 11; the sheet material lifting and conveying mechanism 6 at the loading end rises to the sheet taking position corresponding to the feeding sheet trolley 21 to take the sheet.

[0057] S3. The empty material box 16 determines whether it has reached the board placement position through the in-position sensor 13, and the box conveying rack 12 stops conveying until the empty material box 16 reaches the board placement position; the panels on the input material trolley 21 are conveyed by the input plate lifting and conveying mechanism 6 to the PIN removal platform 51 of the positioning conveying lifting and PIN removal mechanism 5, and are positioned by the CCD camera, and the top corner positioning block 54 is driven by the cylinder to make the panel accurately reach the panel removal position.

[0058] S4. The lifting assembly 52 drives the PIN removal platform 51 to rise, and the flexible pressing plate assembly 56 presses down to cooperate to complete the PIN removal process of the plate.

[0059] S5. The lateral movement mechanism 3 is driven by the servo motor to move, driving the first suction cup mechanism 401 to place the separator paper from the separator paper feed drawer 7 to the receiving position of the box 16.

[0060] S6. The second suction cup mechanism 402 reaches the board taking position of the PIN removal platform 51 through the vertical module 32 in the transverse movement mechanism 3, and sucks a layer of circuit substrate and places it in the box 16. Then the first suction cup mechanism 401 sucks the separator paper and places it in the box receiving position and covers a layer of circuit substrate.

[0061] S7. The first suction cup mechanism 401 returns to the paper feed drawer position 7, and the second suction cup mechanism 402 continues to suck another layer of circuit substrate from the PIN removal platform 51 and places it in the box receiving position.

[0062] S8. The above steps S6 and S7 are repeated repeatedly until the circuit substrate on the PIN removal platform 51 is removed.

[0063] S8. After the box 16 is collected, it is sent to the full box cart 15 at the discharge end through the box conveying mechanism 11 and pushed away.

[0064] S10. The PIN removal platform 51 descends, and the remaining electrical boards, paperboards, and PP cover boards are sent to the discharge board trolley 22 through the lifting and conveying mechanism at the discharge end.

[0065] S11. The unloading panel trolley 22 leaves, and the unloading of a group of panels is completed.

[0066] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
