Description

Technical Field

[0001] The present application relates to the field of cable processing technology, and in particular to a carrier and welding equipment for welding a cable core wire to a PCB board. Background Art

[0002] The data cable usually refers to a data transmission cable, such as a USB data cable, which generally includes a cable and connectors at both ends of the cable. When producing the aforementioned data cable, it is generally necessary to cut the rolled cable into a rated length, then electrically connect the core wires in the cable to the corresponding terminals in the connector, and then assemble the connector to the electrical connection to finally produce the aforementioned data cable.

[0003] At present, when producing data cables, it is necessary to pre-process the ends of the cables first. Figure 1 As shown, a common cable structure generally includes a plurality of core wires 14, and an aluminum foil layer 15 disposed on the periphery of the core wires 14. The aluminum foil layer 15 is used to prevent electromagnetic interference and improve transmission efficiency. The aluminum foil layer 15 is coated with a braided layer 16. The braided layer 16 is used to improve the toughness of the product and prevent the aluminum foil layer 15 from falling off. The braided layer 16 is coated with an insulating layer 17. When processing the data cable, the cable end needs to be pre-processed first, that is, the layer structure around the core wire 14 is peeled off to expose the core wire 14 at the cable end, and then the core wire 14 is welded to the PCB board on the connector to achieve electrical connection between the core wire 14 and the connector.

[0004] Before welding, a preset carrier is generally used to fix the cable core wire and the PCB respectively, so as to pre-position the core wire and the PCB board, which is convenient for subsequent welding. The current carrier is generally provided with a slot for inserting the PCB board. In order to fix the PCB board, the slot size is generally adapted to the PCB, that is, the PCB board fits the inner wall of the slot. When the PCB board needs to be taken out of the carrier after welding is completed, since the slot and the PCB board are adapted for plugging, this plugging method will not be convenient for removing the PCB board from the slot, so it needs to be improved. Summary of the invention

[0005] In order to realize convenient loading and unloading of a carrier, cables and PCB boards, the present application provides a carrier and welding equipment for welding cable core wires and PCB boards.

[0006] The present application provides a carrier for welding a cable core wire to a PCB board, which adopts the following technical solution: A carrier for welding cable core wires to PCB boards, comprising a first mold for loading cables, and a second mold for loading PCBs, wherein the top surface of the second mold is provided with a slot for inserting the PCB board, and a fixing piece is provided between the first mold and the second mold, wherein the fixing piece is used to fix the first mold and the end of the second mold together; and when the first mold and the second mold are fixedly connected, the core wire in the first mold fits exactly against the surface of the PCB board in the second mold; and further comprising an upper ejection assembly, wherein the upper ejection assembly is used to drive the PCB board in the slot to move up and out of the slot.

[0007] By adopting the above technical solution, when it is necessary to weld the PCB board and the core wire, the cable can be loaded into the first mold, the PCB board can be inserted into the slot of the second mold, and then the first mold and the second mold can be connected with a fixing part, so that the core wire at the end of the cable fits the PCB surface, and the core wire and the PCB board are positioned; after welding is completed, the upper ejection component can be used to eject the PCB board out of the slot to facilitate the removal of the PCB board, thereby improving the efficiency of loading and unloading molds.

[0008] Preferably, a mounting socket for cable insertion is provided on the surface of the first mold, and a rotating rod is rotatably connected to the first mold, and a cover plate for opening and closing the mounting socket during the rotation of the rotating rod is connected to the side wall of the rotating rod; the upper top assembly includes a gear set, a connecting rod, a docking plate, and a linkage piece; the connecting rod is rotatably connected to the second mold, and when the first mold and the second mold are fixedly connected under the drive of the fixing member, the connecting rod is connected to the rotating rod key and is coaxially arranged, the docking plate is rotatably connected to the second mold, the gear set is used to drive the docking plate to rotate when the connecting rod rotates, the linkage piece is located in the slot, and the linkage piece is connected to the side wall of the docking plate, and when the PCB board is inserted in the slot, the linkage piece is located between the bottom of the slot and the PCB board; when the rotating rod rotates to make the cover open the mounting socket, the docking plate rotates and causes the linkage piece to move in a direction away from the bottom of the slot.

[0009] By adopting the above technical solution, after completing welding, the operator needs to open the installation socket and take out the cable from the installation socket. During the process of opening the installation socket, the rotating rod rotates, and the connecting rod rotates with the rotation of the rotating rod. The gear set drives the docking plate to rotate when the connecting rod rotates, and then the linkage plate moves in the direction away from the bottom of the slot as the docking plate rotates, so that the PCB board located in the slot is detached from the slot under the push of the linkage plate, which makes it convenient for the operator to take out the PCB board and improves the disassembly and assembly efficiency.

[0010] Preferably, a driving member is further provided on the second mold, and the driving member is used to drive the PCB board on the second mold to move along the length direction and / or width direction of the second mold.

[0011] By adopting the above technical solution, the PCB board on the second mold is driven to move by the driving member to adjust the position of the PCB board relative to the core wire, ensuring that the contact position of the core wire and the PCB board is exactly the point to be welded, thereby improving the accuracy of subsequent welding. Moreover, since the core wire in the cable is generally relatively small, and the size of the PCB board is much larger than the core wire, compared with adjusting the welding position of the core wire and the PCB board by moving the core wire, adjusting the position of the PCB to achieve the positioning operation of the welding point of the core wire and the PCB board is more efficient and convenient.

[0012] Preferably, it comprises a visual display device, a controller, a welding mechanism, and the carrier for welding the cable core wire and the PCB board as claimed in claim 1; the visual display device is electrically connected to the controller, the driving member and the welding mechanism are controlled by the controller, the visual display device is used to obtain a position image, the position image is an image of the positional relationship between the core wire on the first mold and the second mold fixedly connected by a fixing member and the PCB board, the controller is used to obtain the position image, and determine the welding point on the PCB board based on the position image, and control the driving member to drive the PCB board in the slot to move so that the corresponding core wire fits the welding point on the PCB board, and the controller is also used to control the welding mechanism to start and weld the welding point on the PCB board.

[0013] By adopting the above technical scheme, an image with the position relationship between the core wire and the PCB board (i.e., a position image) is captured by a visual display device, a controller is used to automatically analyze the welding points on the PCB board used for welding with the core wire, the controller controls the driving member to drive the PCB board to move, that is, adjust the position of the PCB board, and move the PCB board so that the core wire can fit with the corresponding welding points, and finally the controller controls the welding mechanism to weld the aforementioned welding points; in summary, automatic docking, positioning and welding of the welding position of the core wire and the PCB board are achieved. Compared with the method of manually adjusting the position of the core wire with tweezers and moving the core wire to the corresponding welding point, the technical scheme of the present application involves less manual participation, and uses an automated operation method to improve welding efficiency. At the same time, it can also avoid the inaccurate positioning caused by manual positioning operations, thereby improving welding quality.

[0014] Preferably, it also includes a vibrating screen plate, a first conveyor belt, a receiving plate and an adsorption mechanism; the vibrating screen plate is used to supply PCB boards; there are several receiving plates, which are arranged sequentially along the conveying direction of the first conveyor belt, and the receiving plate can move to the outlet of the vibrating screen plate with the movement of the first conveyor belt, and receive the PCB boards output from the outlet of the vibrating screen plate, and the PCB boards on the receiving plate are arranged sequentially along the length direction of the receiving plate, and the adsorption mechanism is used to adsorb the PCB boards on the receiving plate into the slots of the second mold.

[0015] By adopting the above technical solution, a vibrating screen plate and a receiving plate are provided to realize the supply of PCB boards, and the vibrating screen plate and the receiving plate can supply the PCB boards one by one, making it convenient for the adsorption mechanism to absorb the PCB boards one by one from the receiving plate, thereby realizing one-to-one loading of the PCB boards and the slots, further reducing manual participation, and improving the loading efficiency of the PCB boards and the second mold.

[0016] Preferably, a first rotating shaft is provided between the receiving plate and the first conveyor belt, a frame is arranged around the periphery of the first conveyor belt, and an upper surface of the frame close to the outlet of the vibrating screen plate is provided with a first docking surface for fitting with the lower surface of the receiving plate, and the first docking surface is used to make the receiving plate rotate around the first rotating shaft when fitting with the receiving plate, and to make one end close to the outlet of the vibrating screen plate tilt upward.

[0017] By adopting the above technical scheme, when the receiving plate moves to the outlet of the vibrating screen disk along with the transmission of the first conveyor belt, the lower surface of the receiving plate will fit with the first docking surface, and under the limiting action of the first docking surface, the receiving plate will rotate around the first rotating shaft, and the end of the receiving plate close to the outlet of the vibrating screen disk will be tilted upward, so that the PCB board output from the outlet of the vibrating screen disk can be quickly moved to the receiving plate under the guiding action of the inclined receiving plate, and arranged in an orderly manner on the receiving plate along the length direction of the receiving plate; the first conveyor belt can be controlled by the controller, so that the start and stop of the first conveyor belt can be controlled by the controller, so that a number of receiving plates can receive the PCB boards output from the outlet of the vibrating screen disk in an orderly manner.

[0018] Preferably, the adsorption mechanism includes a suction cup, an adsorption member for controlling a preset adsorption port of the suction cup to form a negative pressure, an adjusting member for driving the suction cup to rotate, and a moving member for driving the suction cup to move back and forth between the receiving plate and the second mold; the adjusting member and the adsorption member are controlled by a controller, and the controller is also electrically connected to an identifier, and the identifier is used to identify the orientation of each PCB board on the receiving plate relative to the receiving plate and obtain first identification information. The controller is used to obtain the first identification information identified by the identifier, and is also used to control the adsorption member to drive the suction cup to adsorb the PCB board on the receiving plate, control the moving member to drive the suction cup to move, and control the adjusting member to drive the suction cup to rotate based on the first identification information of the adsorbed PCB board, so that the PCB board is inserted into the slot of the second mold in a specified orientation.

[0019] By adopting the above technical scheme, since the PCB output from the outlet of the vibrating screen plate to the receiving plate is inconsistent in direction relative to the receiving plate, when the PCB board is finally inserted into the slot of the second mold, it is necessary to require that the end of the PCB board with the welding point faces the periphery of the slot for subsequent welding with the core wire. Therefore, before the PCB board is inserted into the slot of the second mold, the orientation of the PCB board needs to be corrected, and the correction method proposed in this scheme is to identify the PCB boards on the receiving plate one by one by an identifier, and before the moving part transfers the PCB board to the second mold, the adjusting part is used to drive the suction cup to rotate during the transfer process, so that the PCB board adsorbed by the suction cup rotates, thereby realizing the adjustment of the PCB orientation, so that the orientation of the PCB finally inserted into the slot of the second mold remains consistent, and is the insertion orientation required for welding, so as to realize automatic and efficient adjustment of the installation position of the PCB board relative to the second mold during the automatic loading process of the PCB and the second mold.

[0020] Preferably, the identifier is also used to identify the positive and negative directions of each PCB board on the receiving plate and obtain second identification information; it also includes a correction component, which is used to drive the PCB board on the receiving plate to flip, and the controller is used to obtain the second identification information obtained by the identifier, and based on the second identification information, control the adsorption mechanism to adsorb the PCB board on the receiving plate with the second identification information as the positive direction to the second mold.

[0021] By adopting the above technical scheme, since it is impossible to ensure the front and back of the PCB board output from the outlet of the vibrating screen plate to the receiving plate, when the PCB board is finally inserted into the slot of the second mold, it is required that the side of the PCB board with the welding point faces upward (that is, the positive direction mentioned above) so that the core wire can fit with the upper surface of the PCB board for welding. For this reason, the identifier involved in the present application can not only identify the orientation of the PCB, but also identify the front and back sides of the PCB (that is, the positive and reverse directions), and control the adsorption mechanism to only adsorb the PCB board with the front side facing upward (that is, the positive direction) into the second mold. For the PCB board stranded on the receiving plate and on the back line, the present application provides a correction component that can be used to flip the aforementioned PCB board. The PCB board that was originally reversed can be adjusted to the positive direction by flipping the PCB board 180° through the correction component, and then it can be adsorbed by the adsorption mechanism.

[0022] Preferably, the correction component includes an arc-shaped baffle, a bearing plate, a recovery plate, a linkage rack, a linkage gear, a bevel gear set, and a reset torsion spring; the arc-shaped baffle is located at the periphery of the end of the first conveyor belt, and is used to fit with the receiving plate when the receiving plate moves along the end of the first conveyor belt, so as to enclose a closed space together with the receiving plate; the bearing plate is rotatably connected to one side of the arc-shaped baffle through the reset torsion spring, and the bearing plate is located below the moving path of the receiving plate when the receiving plate moves with the first conveyor belt, and when the reset torsion spring is not deformed, the length direction of the bearing plate is parallel to the length direction of the receiving plate; The carrying plate is rotatably connected to the frame via a rotating shaft, the recovery plate is tilted on the frame, the carrying plate is located at one end of the recovery plate in the length direction, and the carrying plate can be rotated to the extension line of the length direction of the recovery plate; the linkage gear is rotatably connected to the frame, and each receiving plate is correspondingly connected to a linkage rack, and the linkage rack is used to rotate with the linkage gear during the movement of the corresponding receiving plate, and the bevel gear group drives the carrying plate to rotate when the linkage gear rotates.

[0023] By adopting the above technical solution, when the receiving plate moves from one side of the first conveyor belt to the other side of the first conveyor belt, the receiving plate will be reversed. Therefore, the present application uses this movement and reversal of the receiving plate to drive the reverse PCB board stranded in the receiving plate to flip. Specifically, in order to prevent the receiving plate from separating from the PCB in the receiving plate during the movement of the receiving plate, the present application specially arranges an arc-shaped baffle at the end of the first conveyor belt. The arc-shaped baffle is adapted to the movement path of the receiving plate when the receiving plate is reversed, and is always in contact with the open position of the receiving plate during the movement and reversal of the receiving plate, so that the PCB board It is confined in a closed space surrounded by a receiving plate and an arc-shaped baffle. When the receiving plate is rotated to the bottom of the first conveyor belt, that is, when the receiving plate completes the reversal, the receiving plate will continue to move to the top of the carrying plate along with the movement of the first conveyor belt, so that the PCB board falls onto the carrying plate under the action of its own weight. Thereafter, the receiving plate continues to move, and during the movement, with the help of the transmission action of the linkage rack, linkage gear and bevel gear set, the carrying plate is tilted to be in line with the recovery plate, so that the PCB board on the carrying plate is transferred to the recovery plate, and the adsorption mechanism can be controlled to adsorb the PCB board on the recovery plate.

[0024] Preferably, it also includes a carrying frame, a second conveyor belt, and a splicing component, wherein the carrying frame is used to place the first mold loaded with cables, and the first molds in the carrying frame are stacked along the height direction of the carrying frame, the second conveyor belt is used to convey the second mold to one side of the open position at the bottom end of the carrying frame, and the splicing component is used to drive the corresponding fixing component to fix and splice the first mold at the bottom open position of the carrying frame and the second mold conveyed to one side of the bottom open position of the carrying frame to form a carrier, and push the carrier away from the bottom of the carrying frame.

[0025] By adopting the above technical solution, the second mold loaded with the PCB board is conveyed to one side of the bottom of the carrying frame by using the second conveyor belt, and then the first mold at the bottom of the carrying frame and the second mold located on one side thereof are fixedly assembled by using the assembly parts with the help of fixing parts, so as to finally form a carrier, and then the carrier is pushed away from the bottom of the carrying frame. After the carrier is pushed away from the bottom of the carrying frame, the first mold in the carrying frame will continue to fall under the action of its own weight, so as to realize the conveyance of the first mold.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the PCB board and the core wire need to be welded, the cable can be loaded into the first mold, the PCB board can be inserted into the slot of the second mold, and then the first mold and the second mold can be connected with a fixing piece, so that the core wire at the end of the cable fits the PCB surface, and the core wire and the PCB board are positioned; after welding is completed, the upper ejection assembly can be used to eject the PCB board out of the slot, so as to facilitate the removal of the PCB board and improve the efficiency of loading and unloading molds; 2. Use a visual display device to capture an image (i.e., a position image) showing the position relationship between the core wire and the PCB board, use a controller to automatically analyze the welding points on the PCB board used for welding with the core wire, control the driving member through the controller to drive the PCB board to move, that is, adjust the position of the PCB board, move the PCB board so that the core wire can fit with the corresponding welding points, and finally control the welding mechanism through the controller to weld the aforementioned welding points; in summary, automatic docking, positioning, and welding of the welding position of the core wire and the PCB board are achieved. Compared with the method of manually adjusting the position of the core wire with tweezers and moving the core wire to the corresponding welding point, the technical solution of the present application involves less manual participation, and uses an automated operation method to improve welding efficiency. At the same time, it can also avoid the inaccurate positioning caused by manual positioning operations, thereby improving welding quality. BRIEF DESCRIPTION OF THE DRAWINGS

A fixing member 3 is also provided between the first mold 1 and the second mold 2. The fixing member 3 specifically includes a fixing rod 31 arranged at the end of the second mold 2. The end wall of the first mold 1 facing the fixing rod 31 is provided with a fixing hole for the fixing rod 31 to be inserted through interference. The first mold 1 and the second mold 2 are plugged and fixed by inserting the fixing rod 31 into the fixing hole to utilize the friction resistance between the fixing rod 31 and the inner wall of the fixing hole.

[0039] Reference Figure 2 , Figure 3 and Figure 4 , and also includes an upper top component 4, which includes a gear set 41, a connecting rod 42, a docking plate 42 and a linkage piece 44. The connecting rod 42 is rotatably connected to the second mold 2, and a connecting hole is opened on the end wall of the rotating rod 12. When the fixing rod 31 is inserted into the fixing hole 32, the preset rectangular block at the end of the connecting rod 42 is inserted into the connecting hole of the rotating rod 12, and the connecting hole is a rectangular hole adapted to the end of the connecting rod 42, so that the connecting rod 42 and the rotating rod 12 are key-connected, and the connecting rod 42 can rotate coaxially with the rotating rod 12.

[0040] The docking plate 42 is rotatably connected to the second mold 2 via a rotating shaft, and the gear set 41 includes two bevel gears meshing with each other, and one of the bevel gears is fixedly sleeved on the connecting rod 42, and the other bevel gear is fixedly sleeved on the rotating shaft, so that when the rotating rod 12 rotates, the connecting rod 42 and the docking plate 42 can rotate together. The linkage piece 44 is connected to the side wall of the docking plate 42, and the linkage piece 44 fits the bottom of all slots 21 of the second mold 2. When the PCB board is inserted into the slot 21, the linkage piece 44 is located between the PCB board and the bottom of the slot 21. When the rotating rod 12 rotates and drives the cover plate 13 to open the installation socket 11, the connecting rod 42 and the docking plate 42 rotate, so that the linkage piece 44 moves in a direction away from the bottom of the slot 21, so that the PCB board in the slot 21 can be pushed out of the slot 21 with the help of the linkage piece 44, so as to realize the convenient disassembly of the PCB board and the second mold 2.

[0041] Reference Figure 2 and Figure 4The second mold 2 is also provided with a driving member 5, which is arranged in a one-to-one correspondence with the slot 21. The driving member 5 specifically includes a base 51, a bottom plate 52 and two groups of motor screw assembly structures 53; the base 51 is used for inserting the PCB board, and the lower end of the base 51 is provided with an insertion block 54 inserted on the bottom plate 52, one group of motor screw assembly structures 53 is arranged on the insertion block 54 and is threadedly connected to the base 51, so as to drive the PCB board and the base 51 to reciprocate along the X direction, and the other group of motor screw assembly structures 53 is arranged on the second mold 2, and is threadedly connected to the bottom plate 52, so as to drive the bottom plate 52, the base 51 located on the bottom plate 52, and the PCB board to move back and forth along the Y direction in the figure; thereby adjusting the position of the PCB board relative to the slot 21, so that in the subsequent welding process, by adjusting the position of the PCB board relative to the slot 21, the surface of the PCB board and the welding point for welding with the core wire 14 are moved to fit with the end of the core wire 14, so as to facilitate the precise focusing of the core wire 14 and the PCB welding point, thereby improving the welding efficiency and welding accuracy.

[0042] Example 2 Embodiment 2 of the present application discloses a cable core wire and PCB board welding device, referring to Figure 5 and Figure 6 , which includes the carrier for welding the cable core wire and the PCB board in Example 1 (hereinafter referred to as the carrier); and also includes a visual display device 61, a controller 6 and a welding mechanism 7. The welding mechanism 7 includes a welding table 71, a first cylinder 72 disposed on the welding table 71, and a welding gun 73 installed at the driving end of the first cylinder 72, and the welding gun 73 faces the upper surface of the welding table 71. The welding gun 73 and the first cylinder 72 are both controlled by the controller 6, which can be a PLC controller. The visual display device 61 is electrically connected to the controller 6, and the visual display device 61 is an electronic magnifying glass, which is used to capture the electronic image of the surface of the welding table 71 and magnify the aforementioned electronic image. Correspondingly, if a carrier loaded with cables and PCB boards is placed on the welding table 71, then the aforementioned electronic image will be an image containing the carrier, and it is an image of the carrier after magnification, and the magnification factor can enable the operator to clearly know each core wire and each preset welding point on the surface of the PCB board. The controller 6 is used to obtain the aforementioned electronic image, and based on the aforementioned electronic image and the pre-stored reference image, determine the welding points on the surface of the PCB board and the core wires corresponding to each welding point. Specifically, the reference image can be a connection image of the PCB board and the core wire that has been welded, and the reference image shows the one-to-one correspondence between each core wire and the welding point of the PCB board.

[0043] Accordingly, before welding, the controller 6 can first determine all welding points on the PCB board according to the reference image, and then determine the core wire corresponding to each welding point according to the core wire color, as well as the position of the current corresponding core wire end, wherein both the welding point and the core wire position can be represented in coordinate form. The embodiment of the present application proposes that the welding gun 73 will weld the core wires to the PCB board one by one, so before welding the target core wire to the PCB board, the controller 6 will control the driving member 5 to drive the PCB board to move, so that the welding point corresponding to the target core wire on the surface of the PCB board moves to fit with the target core wire end, and then control the first cylinder 72 to drive the welding gun 73 to move downward and control the welding gun 73 to weld the target core wire end. Among them, the target core wire refers to any core wire, and this application assumes that all core wires have different colors, so as to achieve a one-to-one correspondence between the core wires and the welding points; in addition, the welding table 71 can be provided with a mechanism for driving the welding gun 73 to move along the X direction and the Y direction respectively (not shown in the figure, such as two sets of motor screw combination structures), so that the welding gun 73 can be moved to the top of the welding point between the target core wire and the PCB board to facilitate welding.

One side of the connecting plate 84 is rotatably connected to the first rotating shaft 841, and the side of the first rotating shaft 841 away from the first supporting plate 842 is fixedly connected to the second supporting plate 844, and the side of the second supporting plate 844 away from the first rotating shaft 841 is rotatably connected to the second rotating shaft 843, and the side wall of the second rotating shaft 843 away from the second supporting plate 844 is fixedly connected to the lower surface of the supporting plate 84, and the first rotating shaft 841 and the second rotating shaft 843 are respectively sleeved with torsion springs.

Photoelectric switches (not shown in the figure) can be installed on both sides of the frame 8 near the outlet of the vibrating sieve plate 81 to detect whether the receiving plate 84 moves to the bottom of the outlet of the vibrating sieve plate 81. When the receiving plate 84 moves between the photoelectric switches, it is considered that the receiving plate 84 moves to the bottom of the outlet of the vibrating sieve plate 81. At this time, the controller 6 suspends the transmission of the first conveyor belt 82 and opens the preset discharge valve (not shown in the figure) at the outlet of the vibrating sieve plate 81, so that the PCB board falls onto the receiving plate 84 through the outlet of the vibrating sieve plate 81.

[0046] Reference Figure 5 , Figure 6 and Figure 7 , the surface of the frame 8 near the outlet of the vibrating sieve plate 81 is provided with a first docking surface 821. When the receiving plate 84 moves to fit with the first docking surface 821 with the transmission of the first conveyor belt 82, the receiving plate 84 will rotate around the second rotating shaft 843, and one end of the receiving plate 84 near the outlet of the vibrating sieve plate 81 is tilted upward, and the other end is tilted downward, so that the PCB boards dropped from the outlet of the vibrating sieve plate 81 can be quickly and orderly arranged and placed on the receiving plate 84 under the guidance of the tilted receiving plate 84. In addition, whenever the discharge valve is opened, the controller 6 can count through the built-in timer. When the timing reaches the specified time, it is considered that the length direction of the single receiving plate 84 has been filled with PCBs. At this time, the controller 6 can close the zeroing timer, close the discharge valve and restart the first conveyor belt 82.

[0047] Reference Figure 5 , Figure 6 and Figure 7 The adsorption mechanism 9 includes a bracket 91, a support plate 92 disposed on the bracket 91, a suction cup 93 disposed on the lower surface of the support plate 92, an adjusting member 94 for driving the suction cup 93 to rotate, an adsorption member 95 for controlling the formation of negative pressure at the preset adsorption port on the lower surface of the suction cup 93, and a moving member 96 for driving the support plate 92 to move. Among them, the moving member 96 includes a second cylinder 961 for driving the support plate 92 to rise and fall, a third cylinder 962 for driving the support plate 92 to reciprocate along the Z direction (Z direction is parallel to the length direction of the receiving plate 84) shown in the figure, and a first motor 963 for driving the bracket 91 to rotate; a second conveyor belt 83 is provided on one side of the adsorption mechanism 9, and the adsorption mechanism 9 can adsorb the PCB board on the receiving plate 84 in the P area shown in the figure to the slot 21 of the second mold 2 inserted into the Q area on the second conveyor belt 83.

[0048] Reference Figure 5 , Figure 6 and Figure 7Specifically, the support plate 92 is driven to rotate by the first motor 963 and is driven to move by the third cylinder 962, so that the support plate 92 can be moved to the top of any PCB board (hereinafter referred to as the target PCB board) on the receiving plate 84 in the P area, or to the top of the slot 21 in the second mold 2 in the Q area of ​​the second conveyor belt 83; the support plate 92 is driven downward by the second cylinder 961, so that the suction cup 93 can be attached to the surface of the target PCB board, and then the suction part 95 is used to control the surface of the suction cup 93 to form a negative pressure, so that the target PCB board can be taken out of the receiving plate 84, and finally placed in the slot 21 in the Q area.

[0049] The controller 6 is also electrically connected to an identifier 62, which can be a camera device for identifying each PCB board in the receiving plate 84 moved to the M area, and obtaining first identification information and second identification information. Specifically, the identifier 62 collects image information of each PCB board in the receiving plate 84 in the M area, and the controller 6 is used to receive the image information and compare the image information with the pre-stored basic image, and generate the first identification information and second identification information of each PCB board based on the comparison result. The controller 6 is used to record the position information of each PCB board in the M area on the receiving plate 84 to which it belongs, and the corresponding first identification information and second identification information. Among them, the basic image includes the front image, the back image, and the orientation image of the PCB board. The orientation image refers to the image of the part with the welding point on the PCB when it is oriented in different directions (such as Figure 7 Each orientation image corresponds to a rotation angle of the adjusting member 94, and the rotation angle satisfies: after the PCB board is adsorbed by the suction cup 93 and the suction cup 93 is controlled by the adjusting member 94 to rotate the corresponding rotation angle, the orientation of the PCB board after being inserted into the Q area is as follows Figure 7 As shown. The controller 6 compares the front image and the reverse image in the basic information with the image information collected by the identifier 62. If they are consistent with the front image, the specific content of the second identification information is "front". On the contrary, if they are consistent with the reverse image, the specific content of the second identification information is "reverse". The controller 6 is also used to compare the orientation image in the basic information with the image information collected by the identifier 62, and determine the rotation angle of the adjustment member 94, which is the first identification information.

[0050] Among them, the M area and the P area are arranged sequentially along the conveying direction of the first conveyor belt 82. When the receiving plate 84 of the M area moves to the P area, the controller 6 is used to determine whether the PCB board is on the reverse side according to the second identification information corresponding to the PCB board before the adsorption mechanism 9 adsorbs the PCB on the receiving plate 84 of the P area each time. If so, the PCB board is skipped, and the second identification information of the PCB on the receiving plate 84 is sequentially determined along the length direction of the receiving plate 84 until a PCB board with the second identification information as the front side is found. At this time, the controller 6 will control the suction cup 93 of the adsorption mechanism 9 to move to the top of the front PCB board based on the position information of the front PCB board, and then adsorb the front PCB board. After adsorption and before moving to the second conveyor belt 83, the controller 6 controls the adjustment member 94 to rotate to a rotation angle consistent with the first identification information corresponding to the front PCB board, so that when the front PCB is finally inserted into the slot 21 of the Q area, the orientation of the part with the welding point is as follows: Figure 5 The PCB in the middle Q area is shown.

[0051] Reference Figure 7 and Figure 8 As can be seen from the above, the PCB board with the second identification information on the reverse side will be retained on the receiving plate 84. Accordingly, the present application further includes a correction component 86, which is used to flip the PCB retained on the receiving plate 84 by 180°. The correction component 86 includes an arc baffle 861, a bearing plate 862, a linkage rack 863, a linkage gear 864, a bevel gear set 865, and a reset torsion spring 866. The arc-shaped baffle 861 is arranged on the frame 8 and is located at one end of the first conveyor belt 82. The arc-shaped baffle 861 is arc-shaped and satisfies the following conditions: when the receiving plate 84 moves to one end of the first conveyor belt 82 close to the arc-shaped baffle 861 and moves from above the first conveyor belt 82 to below the first conveyor belt 82, the flexible rubber pad preset on the end wall at the open position of the receiving plate 84 is always in contact with the side wall of the arc-shaped baffle 861, so that the arc-shaped baffle 861 and the receiving plate 84 together enclose a closed space, thereby preventing the PCB board in the receiving plate 84 from detaching from the receiving plate 84 during the rotation of the receiving plate 84. In this process, when the receiving plate 84 moves to below the first conveyor belt 82, the PCB board in the receiving plate 84 is flipped.

[0052] The supporting plate 862 is rotatably connected to the side wall of the arc-shaped baffle 861 through a rotating shaft, and the supporting plate 862 is located below the first conveyor belt 82. The reset torsion spring 866 is sleeved on the rotating shaft at the end of the supporting plate 862. When the reset torsion spring 866 is not deformed, the supporting plate 862 is horizontally set. When the receiving plate 84 moves to below the first conveyor belt 82, the supporting plate 862 is just below the moving path when the receiving plate 84 moves the arc-shaped baffle 861 and continues to move, so as to receive the PCB board that has been flipped in the receiving plate 84.

[0053] A recovery plate 87 is provided at one end of the supporting plate 862. The end of the recovery plate 87 away from the receiving plate 84 is tilted downward. The recovery plate 87 is fixed on the frame 8. The linkage gear 864 is rotatably connected to the side wall of the frame 8 near the supporting plate 862. Each end of the receiving plate 84 corresponds to a linkage rack 863. The linkage gear 864 is located on the moving path of the linkage rack 863 when the linkage rack 863 moves with the receiving plate 84, so as to engage with the linkage rack 863 and rotate as the linkage rack 863 moves. The bevel gear set 865 includes two bevel gears meshing with each other, wherein the bevel gear is coaxially connected with the linkage gear 864, and the other bevel gear is sleeved on the rotating shaft at the end of the carrier plate 862, so as to drive the receiving plate 84 to rotate when the linkage gear 864 rotates, and make the receiving plate 84 tilt downward at one end close to the recovery plate 87, so that the length direction of the receiving plate 84 is located on the extension line of the length direction of the recovery plate 87, so as to facilitate the rapid movement of the PCB on the receiving plate 84 to the recovery plate 87. An additional adsorption structure or a manipulator can be provided to adsorb the PCB on the recovery plate 87 and take it to the second mold 2 of the second conveyor belt 83.

[0055] The discharge port 881 and the baffle plate 882 are both located on the moving path of the assembly 89, and the first mold 1 at the bottom of the carrier frame 88 (hereinafter referred to as the bottom first mold 1) is located in the discharge port 881, and the second mold 2 at one end of the second conveyor belt 83 near the assembly 89 (hereinafter referred to as the end second mold 2) is also located on the moving path of the assembly 89. When the driving end of the assembly 89 extends, the end second mold 2 can be pushed toward the direction close to the bottom first mold 1, and under the obstruction of the baffle plate 882 and the torsion spring, the fixing rod 31 on the end first mold 1 is inserted into the bottom The driving end of the splicing piece 89 is inserted into the fixing hole 32 on the second mold 2 at the bottom, so that the end second mold 2 and the bottom first mold 1 are spliced ​​to form a carrier; when the driving end of the splicing piece 89 continues to extend, the carrier will push the baffle 882 under the push of the splicing piece 89, so that the baffle 882 rotates and opens the discharge port 881, until the carrier is pushed onto the welding table 71, and the driving end of the splicing piece 89 retracts and returns to its original position. Optionally, the controller 6 can also be used to control the welding mechanism 7 to perform welding operations on the carrier on the welding table 71 after each resetting of the splicing piece 89 (the specific operation content of the welding operation is as described above and will not be repeated here).
