When assembling the remote control circuit board, a robot and an assembly positioning fixture are usually used. The robot takes the circuit board and places it in the positioning fixture. Then other robots take the accessories and automatically assemble them with the circuit board in the positioning fixture. This way of robot participation in assembly greatly improves the efficiency of assembly.

[0004] However, the above-mentioned prior art still has shortcomings when used: due to the large number of remote control circuit boards, they are usually placed in a tray, and a plurality of placement slots for placing circuit boards are provided in the tray. When assembling the circuit boards, it is necessary to manually place a single tray in an area that can be taken by the robot.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1-7 A remote control circuit board automatic assembly device includes a device bracket 1 and a tray 2. The tray 2 is provided with a plurality of placement grooves 21 for placing the remote control circuit boards to be assembled. The trays 2 are multiple and have a stacking placement function. In specific implementation, four legs close to the corners can be welded at the bottom of the tray 2, and then sockets that are plug-in compatible with the legs can be welded at the top of the tray 2. The upper and lower adjacent trays 2 are stacked and connected by plugging the sockets and the legs.

[0039] In the present technical solution, a frame platform 11 is arranged on the top of the equipment bracket 1. The frame platform 11 is a rectangular frame structure. The bottom of the frame platform 11 is connected to a bracket 12 near one end and swings back and forth. A telescopic rod 15 is provided for controlling the swing of the bracket 12. The bracket 12 is used to horizontally lift the stacked pallets 2 and a lifting mechanism 13 for lifting the pallet 2 is provided thereon. The swinging setting structure of the bracket 12 has the advantage of being convenient for docking with several stacked pallets 2. That is to say, when the bracket 12 swings outward to the extreme position, the position is the loading position. When the bracket 12 swings down to the extreme position, the position is the position for stably lifting the stacked pallets 2, which is convenient for the subsequent individual extraction of a single pallet 2.

[0040] Specifically, the bracket 12 includes two groove-type hangers 121 and a horizontal positioning carrier plate 122. The two groove-type hangers 121 are distributed front and back and the free ends of the two are hingedly connected to the bottom of the frame 11. The horizontal positioning carrier plate 122 is rotatably and slidingly connected to the opposite sides of the two groove-type hangers 121. The two groove-type hangers 121 are in a parallel state. Under the restriction of the lifting mechanism 13, the horizontal positioning carrier plate 122 is horizontal. When the two groove-type hangers 121 swing, the horizontal positioning carrier plate 122 is always in a horizontal state. The positioning in the horizontal positioning carrier plate 122 means positioning the pallet 2. In specific implementation, a socket for plugging into the legs of the pallet 2 can be opened on the top of the horizontal positioning carrier plate 122. The telescopic rod 15 is an electric push rod, and there are two telescopic rods 15. The bottom of the frame platform 11 and a position at one end are hingedly connected to one end of the telescopic rod 15, and the other end of the telescopic rod 15 is hingedly connected to one side of the adjacent groove-shaped hanger 121. The telescopic rod 15 controls the swing of the groove-shaped hanger 121.

[0041] Furthermore, the bottom of the frame 11 is fixedly connected to a hanging plate 111 hingedly connected to the free end of the groove-shaped hanger 121, and the lifting mechanism 13 includes a lifting screw 131, a transmission shaft 132, a bevel gear set 134 and a control assembly 133. Slideways 1211 are provided on both sides of the groove-shaped hanger 121, and sliders 1221 that are slidably matched with the slideways 1211 are rotatably connected to the two sides of the horizontal positioning carrier 122, and a lifting screw 1221 that is rotatably connected to the slideway 1211 is screwed through the slider 1221. The bottom of the groove-type hanger 121 is provided with a transmission shaft 132, and the transmission shaft 132 is connected to the lifting screw 131 through a bevel gear set 134. Two transmission shafts 132 are installed at the bottom of a groove-type hanger 121. The bevel gear set 134 includes two bevel gears meshing with each other. The control combination 133 is used to control the rotation of the transmission shaft 132. When the lifting screws 131 on the two groove-type hangers 121 rotate synchronously in the same direction, the horizontal positioning carrier 122 will be driven to move up and down horizontally as a whole.

[0042] Among them, the preferred structure of the control combination 133 is that it includes a transmission belt 1331, a transmission pulley 1332 and a control motor 1333. The bottom of both sides of the trough-type hanger 121 are rotatably connected with a transmission shaft 132, one end of the transmission shaft 132 is fixedly connected with a transmission pulley 1332, and one side of the suspension plate 111 is rotatably connected with a transmission pulley 1332 coaxial with the swing axis of the trough-type hanger 121. The transmission pulleys 1332 on the same side are connected through the transmission belt 1331. When the transmission belt 1331 is running, it will simultaneously drive the transmission shafts 132 at the bottom of the two trough-type hangers 121 to rotate synchronously in the same direction through the transmission pulley 1332. A control motor 1333 is fixedly connected between two adjacent suspension plates 111 via a support plate, and the output shaft of the control motor 1333 is fixedly connected to a driving pulley 13331 that engages with a transmission belt 1331, that is, the transmission belt 1331 is a synchronous belt, and the control motor 1333 provides driving force for the rotation of the driving pulley 13331.

[0043] In this embodiment, an extraction mechanism 14 is connected to the frame 11 so as to swing back and forth. The connection position between the extraction mechanism 14 and the frame 11 is located behind the groove-shaped hanger 121. The extraction mechanism 14 has the function of extracting the topmost pallet 2 one by one from the stacked pallets 2. The extraction mechanism 14 splits the topmost pallet 2 and lifts it to the transfer height. At this time, it is convenient for the external XYZ-axis manipulator to take the remote control circuit board from the pallet 2 lifted by the extraction mechanism 14, and then place it on the assembly positioning jig. In specific implementation, several manipulator mounting tables can be fixedly connected to the top of the frame 11. The manipulator mounting tables are connected to the XYZ-axis manipulators by bolts, and then the assembly positioning jig (not shown in the figure) is installed on the top of the frame 11.

[0044] Specifically, two supporting blocks 22 are fixedly connected to the two sides of the tray 2, that is, two supporting blocks 22 are arranged on both sides of a tray 2, and the extraction mechanism 14 lifts the tray 2 by lifting the supporting blocks 22. The extraction mechanism 14 includes a parallel hinge four-bar mechanism 141, an elastic telescopic pull rod 142, a pad 143 and a driving group 144. A parallel hinge four-bar mechanism 141 is connected to both sides of the frame 11, and the bottoms of the upper beams 1411 on the two parallel hinge four-bar mechanisms 141 are connected to the pads 143 for rotation up and down. In specific implementation, ear plates close to the two ends can be welded to the bottom of the upper beam 1411, and then the support shafts rotatably connected to the ear plates can be welded at both ends of the pad 143. The function of the pad 143 is to lift the supporting blocks 22. The pad 143 and the adjacent upper beam 1 The opposite side of 411 is hingedly connected by an elastic telescopic pull rod 142. This setting makes the bottom of the pad 143 swing upward when it is pushed upward, and the elastic telescopic pull rod 142 is compressed. The elastic telescopic pull rod 142 adopts a common connection telescopic structure with a built-in support spring. Therefore, when the pad 143 moves to the top of the tray 2, it swings up when it swings down and touches the support block 22. After it passes over the support block 22, the pad 143 will be reset to a horizontal state under the push of the elastic telescopic pull rod 142. Then, when the parallel hinge four-bar mechanism 141 is controlled to swing up, the pad 143 will lift the entire tray 2 through the support block 22 to the position where the external XYZ robot takes it. In this embodiment, the tray 2 is in the highest position, which is the position where the XYZ robot takes each circuit board in the placement slot 21. The drive group 144 is used to control the synchronous swing of the two parallel hinge four-bar mechanisms 141.

[0045] Specifically, the driving group 144 includes a rack 1441, a driving motor 1442 and a transmission gear 1443. Two positioning plates 112 are fixedly connected to the bottom of the frame platform 11 near both sides. The free ends of the two arms 1412 on the parallel hinge four-bar mechanism 141 are fixedly connected to the positioning shaft 14121 that is rotatably connected to the positioning plate 112. One end of the positioning shaft 14121 is fixedly connected to the transmission gear 1443. One side of the two adjacent positioning plates 112 is slidably connected to the water The racks 1441 are evenly distributed and meshed with the transmission gear 1443. The bottom of the frame 11 near both sides is fixedly connected with a driving motor 1442. The output shaft of the driving motor 1442 is fixedly connected with a driving gear 14421 meshed with the adjacent rack 1441. When the driving motor 1442 drives the driving gear 14421 to rotate, the rack 1441 will slide horizontally. When the rack 1441 slides, it will drive the entire parallel hinge four-bar mechanism 141 to swing through the transmission gear 1443.

[0046] Among them, the extraction mechanism 14 also has the function of releasing the tray 2, that is, after the remote control circuit board in the current tray 2 is extracted, the extraction mechanism 14 can release the current empty tray 2, thereby improving the efficiency of separating the stacked trays 2, and then greatly improving the efficiency of subsequent remote control circuit board assembly.

[0047] Specifically, one side of the upper crossbeam 1411 is provided with positioning notches 14111 near both ends, and the positioning notches 14111 are used in conjunction with the support block 22. The bottom of the pad 143 is slidably connected with a gate plate 1431, that is, when the pad 143 lifts the support block 22, the support block 22 will enter the positioning notch 14111, and the gate plate 1431 can prevent the support block 22 from leaking out of the positioning notch 14111. This arrangement has the advantage of improving the lifting accuracy and stability of the tray 2. One side of the gate plate 1431 is provided with a release notch 14311 near the positioning notch 14111. When the gate plate 1431 slides and the release notch 14311 overlaps with the positioning notch 14111, the support block 22 will directly detach from the positioning notch 14111, and the entire tray 2 will fall by its own weight, so that the extraction mechanism 14 can continue to lift the next tray 2 located at the top.

[0048] In this embodiment, the bottom of the pad 143 is fixedly connected with support plates 1432 near the two ends, and the two ends of the gate plate 1431 are fixedly connected with guide shafts 14312 that penetrate the support plates 1432. A return spring 1433 located between the pad 143 and the adjacent support plates 1432 is sleeved on the guide shaft 14312 near the lifting mechanism 13. Under the action of the return spring 1433, the positioning notch 14111 is in a state of being blocked by the gate plate 1431. The two sides of the frame platform 11 are fixedly connected with trigger plates 113 used in conjunction with the guide shaft 14312. When the parallel hinge four-bar mechanism 141 swings in a direction away from one end of the frame platform 11 until the guide shaft 14312 touches the trigger plate 113, the gate plate 1431 is pushed and the return spring 1433 is compressed. When the release notch 14311 and the positioning notch 14111 coincide with each other, the current tray 2 will be separated, which has the advantage of more convenient and quick control of releasing the tray 2.

[0049] Working principle: when in use, first control the telescopic rod 15 to retract, and the grooved hanger 121 swings up to a position at one end of the frame platform 11. At this time, the operator can place a stack of pallets 2 on the horizontal positioning carrier 122, and then control the telescopic rod 15 to reset until the horizontal positioning carrier 122 is at the bottom, start the control motor 1333, and the active pulley 13331 drives the transmission belt 1331 to operate. At this time, all the transmission pulleys 1332 rotate synchronously in the same direction. Under the transmission of the bevel gear set 134, the lifting screw 131 rotates to drive the horizontal positioning carrier 122 to rise horizontally. When the pallet 2 in the highest position is close to the frame platform 11, the control drive motor 1442 is started, and the active gear 14421 drives the rack 1441 to slide. Under the transmission of the transmission gear 1443, the entire parallel hinge four-bar mechanism 141 swings toward the direction of the pallet 2. When the pad 143 swings down and touches the support block 22, it swings up. When it passes over the support block 22 Under the push of the elastic telescopic pull rod 142, the pad 143 will be reset to a horizontal state, and then when the parallel hinge four-bar mechanism 141 is controlled to swing upward, the pad 143 will lift the entire tray 2 to the external XYZ direction robot position through the support block 22. During this process, the support block 22 will enter the positioning notch 14111 and be limited by the gate plate 1431, and then the XYZ direction robot will be started to start taking each remote control circuit board placed on the tray 2 one by one to the assembly fixture on the assembly station. After the circuit boards on the current tray 2 are taken, the parallel hinge four-bar mechanism 141 is controlled to continue to swing. When the parallel hinge four-bar mechanism 141 swings away from one end of the frame platform 11 until the guide shaft 14312 touches the trigger plate 113, the gate plate 1431 is pushed and the reset spring 1433 is compressed. When the release notch 14311 and the positioning notch 14111 coincide, the current tray 2 will be separated, thereby realizing the rapid release of the empty tray 2. Then the parallel hinge four-bar mechanism 141 is controlled to reset and continue to take the next tray 2 at the highest point.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
