[0002] When a sub-board needs to be mounted on a main board, the current process flow is as follows:

[0060] The present invention provides a printing, inspection and pasting all-in-one machine, a main and sub-board pasting line and a main and sub-board pasting method, which are suitable for the application scenario where the sub-board is directly pasted onto the main board after being printed with solder paste. It can effectively solve the problems of low compactness of equipment structure and overly complicated production process in the existing pasting process.

[0061] Example 1

[0062] See also Figure 1 This embodiment provides a main and auxiliary board placement line, comprising a main board production line 100 and an integrated printing, inspection, and placement machine 200. Specifically, the main board production line 100 comprises, from upstream to downstream along the main board conveying direction, a main board printing and placement machine 100a, an auxiliary board placement machine 100b, and a welding machine 100c. The integrated printing, inspection, and placement machine 200 is located between the main board printing and placement machine 100a and the auxiliary board placement machine 100b.

[0063] In this embodiment, the mainboard printing and placement machine group 100a is used to print the mainboard and then place the mainboard electronic components on the mainboard, that is, the mainboard sent to the printing, inspection and placement all-in-one machine 200 already has the mainboard electronic components placed on it from the beginning. The printing, inspection and placement all-in-one machine 200 is mainly used to print the sub-board and then place the sub-board on the mainboard that has already been placed with the mainboard electronic components; after the sub-board is placed on the mainboard, the sub-board placement equipment 100b places the sub-board electronic components on the sub-board, thereby completing the placement operation of the sub-board; finally, the mainboard and the sub-board are sent to the welding machine group 100c together, and the mainboard and the sub-board are welded at the same time, so that the mainboard electronic components and the sub-board can be welded and fixed on the mainboard, and the sub-board electronic components can be welded and fixed on the sub-board.

[0064] It is worth noting that in the present invention, the mainboard printed circuit board assembly 100a, the auxiliary board printed circuit board assembly 100b, and the welding assembly 100c can all be existing products on the market. The working principles and specific structures of the above three are not the focus of this embodiment and will not be described in detail.

[0065] This embodiment focuses on the specific structure and workflow of the printing, inspection and labeling all-in-one machine 200.

[0066] See also Figure 2 and Figure 3 The printing, inspection and pasting machine 200 includes a mainboard conveying device 200a for transferring the mainboard between the mainboard printing and pasting machine group 100a and the sub-board pasting device 100b, the sub-board production line body 200b for printing the sub-board, and a pasting mechanism 200c for pasting the printed sub-board onto the mainboard sent by the mainboard conveying device 200a.

[0067] In this embodiment, the sub-board production line 200b includes a sub-board feeding device 1 for supplying sub-boards, a printer 2 for printing on sub-boards, a printing feed conveyor 3 for conveying sub-boards from the sub-board feeding device 1 to the printer 2, a transverse transfer robot 4 for transferring the sub-boards from the sub-board feeding device 1 to the printing feed conveyor 3, and a printing discharge conveyor 5 for conveying the sub-boards delivered by the printer 2 to the main board conveyor 200a. The mounting mechanism 200c is used to mount the sub-boards on the printing discharge conveyor 5 onto the main board of the main board conveyor 200a.

[0068] The detailed working process of the main and auxiliary board mounting line provided in this embodiment is as follows:

[0069] S10: After the motherboard printing and placement machine unit 100a completes the printing and placement operation of the motherboard, it sends the motherboard to the motherboard conveying device 200a;

[0070] S20: The sub-board feeding device 1 supplies the sub-board without solder paste printed thereon;

[0071] See also Figure 4 In this embodiment, the sub-plate feeding device 1 includes a fixed feeding platform 101, a lifting feeding platform 102, a lifting feeding linear drive mechanism 103, a lifting transfer platform 104, a lifting transfer linear drive mechanism 105, a lifting receiving platform 106, a lifting receiving linear drive mechanism 107, a longitudinal transfer robot 108, a remote cache platform 109, a near-end cache platform 110, and a fixed transfer platform 111.

[0072] The lifting and feeding platform 102 is located above the fixed feeding platform 101. The lateral transfer robot 4 is used to transfer the sub-boards on the lifting and feeding platform 102 to the printing feed conveyor 3. The driving end of the lifting and feeding linear drive mechanism 103 is connected to the lifting and feeding platform 102, driving the lifting and feeding platform 102 to move up and down relative to the fixed feeding platform 101.

[0073] The lifting transfer platform 104 is located on the side of the fixed feeding platform 101. The driving end of the lifting transfer linear drive mechanism 105 is connected to the lifting transfer platform 104, driving the lifting transfer platform 104 to move up and down relative to the fixed feeding platform 101.

[0074] The lifting material receiving platform 106 is located on the side of the lifting transfer platform 104 away from the fixed material feeding platform 101. The driving end of the lifting material receiving linear drive mechanism 107 is connected to the lifting material receiving platform 106, driving the lifting material receiving platform 106 to move up and down relative to the fixed material feeding platform 101. The longitudinal transfer robot 108 is used to transfer the unloaded fixtures on the lifting material feeding platform 102 to the lifting material receiving platform 106.

[0075] The remote cache platform 109 is fixed below the lifting material receiving platform 106, the proximal cache platform 110 is located on the side of the remote cache platform 109 close to the fixed feeding platform 101, and the fixed transfer platform 111 is fixed above the proximal cache platform 110.

[0076] The sub-plate feeding device 1 provided in this embodiment has the following specific feeding process:

[0077] S201: The upstream AGV moves a stack of fully loaded jigs (with sub-boards without solder paste printed inside) to a position opposite to the fixed feed platform 101, and then delivers a stack of fully loaded jigs to the fixed feed platform 101;

[0078] S202: The lifting transfer linear drive mechanism 105 drives the lifting transfer platform 104 to move downward until it is flush with the fixed feeding platform 101, and the fixed feeding platform 101 transfers the entire stack of fully loaded fixtures to the lifting transfer platform 104;

[0079] Next, the lifting transfer linear drive mechanism 105 drives the lifting transfer platform 104 to move upward until it is flush with the lifting feeding platform 102, and the lifting transfer platform 104 transfers the entire stack of fully loaded fixtures to the lifting feeding platform 102;

[0080] S203: The lateral transfer robot 4 transfers the sub-plate on the lifting feeding platform 102 to the printing feeding conveyor 3;

[0081] S204: When the topmost jig is empty, the longitudinal transfer robot 108 transfers the empty jig to the lifting and receiving platform 106; then, the lifting and feeding platform 102 moves upward by one grid, and the lifting and receiving platform 106 moves downward by one grid; this process repeats until all the sub-plates on the lifting and feeding platform 102 are removed and all the jigs are transferred to the lifting and receiving platform 106;

[0082] It should be noted that, in the process of the lateral transfer manipulator 4 and the longitudinal transfer manipulator 108 cooperating to retrieve materials, the lifting transfer linear drive mechanism 105 drives the lifting transfer platform 104 to move downward until it is flush with the fixed feeding platform 101; the AGV trolley first transports a stack of fully loaded fixtures to the distal buffer platform 109 for buffering via the lifting transfer platform 104 and the proximal buffer platform 110, and then transports another stack of fully loaded fixtures to the proximal buffer platform 110 for buffering via the lifting transfer platform 104; thereby, the internal storage space of the AGV trolley can be freed up for the subsequent recovery of empty fixtures;

[0083] S205: The lifting and receiving linear drive mechanism 107 drives the lifting and receiving platform 106 to move to be flush with the fixed transfer platform 111, and the lifting and transfer linear drive mechanism 105 drives the lifting and transfer platform 104 to move to be flush with the fixed transfer platform 111;

[0084] The lifting material receiving platform 106 transports the empty jig to the lifting transfer platform 104 via the fixed transfer platform 111;

[0085] S206: The lifting and transfer linear drive mechanism 105 drives the lifting and transfer platform 104 to move downward until it is flush with the fixed feeding platform 101. The lifting and transfer platform 104 transfers the empty fixture back to the AGV car via the fixed feeding platform 101;

[0086] S207: The proximal buffer platform 110 transfers the cached fully loaded fixtures to the lifting transfer platform 104. Then, the lifting transfer linear drive mechanism 105 drives the lifting transfer platform 104 to move upward until it is flush with the lifting feeding platform 102, and transfers the fully loaded fixtures to the lifting feeding platform 102.

[0087] This reciprocating process can supply the fully loaded fixtures on the remote buffer platform 109 to the lifting feeding platform 102, and finally all the empty fixtures can be recovered and sent back to the AGV car.

[0088] Optionally, there are two sub-board feeding devices 1, and the two sub-board feeding devices 1 are symmetrically arranged about the printing feed conveyor 3. The two sub-board feeding devices 1 sequentially feed the printing feed conveyor 3 through the lateral transfer robot 4 to improve the feeding efficiency of the sub-boards.

[0089] S30: The lateral transfer robot 4 delivers the secondary board supplied by the secondary board feeding device 1 to the printing feed conveyor 3; then, the printing feed conveyor 3 delivers the secondary board to the printing press 2, which prints the secondary board by screen printing or other methods. The printed secondary board is then delivered to a position near the main board conveyor 200a via the printing discharge conveyor 5.

[0090] It should be noted that the printing machine 2 can be an existing product on the market. Its working principle and specific structure are not the focus of the present invention and will not be described in detail.

[0091] In this embodiment, the printing material output conveyor 5 and the mainboard conveyor 200a are both located above the printing material feed conveyor 3. The printing material output conveyor 5 and the printing material feed conveyor 3 are parallel to each other; the mainboard conveyor 200a and the printing material feed conveyor 3 are perpendicular to each other.

[0092] Such a structural layout allows the mainboard conveying device 200a, the printing feed conveying device 3, and the printing discharge conveying device 5 to be staggered with each other to fully utilize the space, greatly improving the structural compactness and reducing the overall volume of the equipment.

[0093] Furthermore, the length of the printing material discharging conveyor 5 is smaller than the length of the printing material feeding conveyor 3 so as to reserve installation space for the mainboard conveyor 200a.

[0094] S40: The mounting mechanism 200c mounts the sub-board on the printing discharge conveyor 5 onto the main board delivered by the main board conveyor 200a.

[0095] In this embodiment, the placement mechanism 200c includes a placement robot and a CCD component installed on the placement robot and used for visually inspecting the sub-board.

[0096] Optionally, the CCD component can not only be used to visually locate the sub-board so that the mounting robot can accurately grasp the sub-board, but also to visually inspect the printing quality of the sub-board to detect whether there is any missing printing or printing pattern errors.

[0097] It should be noted that at this time, the sub-board mounted on the main board is a bare board and has not yet been mounted.

[0098] S50: The secondary board mounting device 100b performs a mounting operation on the secondary board, mounting the secondary board electronic components onto the secondary board;

[0099] S60: The main board and the auxiliary board are sent together to the welding unit 100c, and the welding unit 100c performs welding operations on the main board and the auxiliary board simultaneously.

[0100] Optionally, reflow soldering is used for soldering. Since the main board and the sub-board enter the soldering unit 100c together, the following can be achieved simultaneously:

[0101] ①Fully secure the motherboard electronic components to the motherboard;

[0102] ② Completely fix the electronic components on the sub-board to the sub-board;

[0103] ③Fully secure the sub-board to the main board.

[0104] The integrated printing, inspection, and pasting machine 200 provided in this embodiment couples the machine to the mainboard production line. On the one hand, the mainboard conveyor 200a, the secondary board production line 200b, and the placement mechanism 200c are highly integrated, greatly improving the compactness of the equipment. On the other hand, the printed secondary board is first placed on the mainboard, then the secondary board is placed, and finally the mainboard and secondary boards are uniformly soldered, reducing the traditional two independent soldering operations to a single soldering operation, effectively reducing the complexity of the production process. Therefore, the integrated printing, inspection, and pasting machine 200 provided by the present invention can be coupled to the mainboard production line, thereby cooperating to solve the problems of low equipment structure compactness and overly complicated production processes in existing placement processes.

[0105] In summary, the printing, inspection and pasting all-in-one machine 200 and the main and auxiliary board placement line provided in this embodiment have the following beneficial effects:

[0106] ① The mainboard conveying device 200a, the sub-board production line body 200b, and the placement mechanism 200c are highly integrated, which greatly improves the compactness of the equipment;

[0107] ② First, the printed sub-board is mounted on the main board, then the sub-board is mounted, and finally the main board and sub-board are welded together. This reduces the traditional two independent welding operations to one welding operation, greatly optimizing the process of turnover of sub-board materials. It not only greatly improves the compactness of the equipment and reduces the equipment cost of the welding unit, but also effectively reduces the complexity of the production process and improves production efficiency.

[0108] ③ The auxiliary plate feeding device 1 can first empty the AGV car, and then send all the empty fixtures back to the AGV car, so that the AGV car can bring the empty fixtures back to the upstream equipment when returning, which is beneficial to improving the turnover efficiency of the fixtures.

[0109] It should be noted that the linear drive mechanism mentioned in the present invention may be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or a motor-screw linear module, and the rotary drive mechanism mentioned in the present invention may be a brushed motor, a brushless motor, or a rotary cylinder. The present invention does not limit the specific structural forms of the linear drive mechanism and the rotary drive mechanism.

[0115] D. Solder and fix the electronic components of the auxiliary board to the auxiliary board, and solder and fix the electronic components of the main board and the auxiliary board to the main board; specifically, this step is performed by a welding unit.

[0116] The main and sub-board mounting method provided in this embodiment has at least the following advantages: first, the printed sub-board is mounted on the main board, and then the sub-board is mounted, and finally the main board and the sub-board are uniformly welded, reducing the traditional two independent welding operations to one welding operation, greatly optimizing the process of turnover of sub-board materials, not only greatly improving the compactness of the equipment and reducing the equipment cost of the welding unit, but also effectively reducing the complexity of the production process and improving production efficiency.
