Description

Technical Field

[0001] The present invention relates to the technical field of remote control circuit board assembly, and particularly to an automatic assembly device for remote control circuit boards. Background Art

[0002] Remote controls usually use radio technology to remotely control by transmitting wireless signals. When a user presses a button on the remote control, the internal circuit board encodes the corresponding instruction into a wireless signal, and then uses an antenna to transmit the signal to the controller or device.

[0003] Currently, in the production process of remote controls, due to the optimized design of the circuit board, the production of remote controls can usually be completed directly by assembly. When assembling the remote control circuit board, a manipulator and an assembly positioning fixture are usually used. After the manipulator picks up the circuit board, it places it in the positioning fixture, and then other manipulators pick up the accessories and complete the automatic assembly with the circuit board in the positioning fixture. This way of assembly involving manipulators greatly improves the assembly efficiency.

[0004] However, the above-mentioned prior art still has deficiencies in use: Since the number of remote control circuit boards is large, they are usually placed in trays, and multiple placement slots for placing circuit boards are provided in the trays. When assembling the circuit boards, it is necessary to manually place a single tray in the area that can be picked up by the manipulator. When the circuit boards in the tray are all picked up, it is necessary to manually remove the empty tray and then place the tray full of circuit boards. Therefore, this kind of manual loading and unloading assembly equipment has the defects of high labor intensity, low production efficiency, and low degree of assembly automation.

[0005] Therefore, the present invention proposes an automatic assembly device for remote control circuit boards. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0037] Embodiment 1

[0038] Please refer to Figure 1-7 , a remote control circuit board automatic assembly device, including an equipment bracket 1 and a tray 2. A plurality of placing grooves 21 are opened on the tray 2, and the placing grooves 21 are used for placing the remote control circuit boards to be assembled. There are multiple trays 2 and they have a stacking function. Specifically, during implementation, four legs can be welded at the bottom of the tray 2 near the corners, and then socket sleeves inserted and matched with the legs are welded on the top of the tray 2. The upper and lower adjacent trays 2 are stacked and connected through the insertion and matching of the socket sleeves and the legs.

[0039] In this technical solution, a frame platform 11 is provided at the top of the equipment support 1. The frame platform 11 is of a rectangular frame structure. At a position near one end of the bottom of the frame platform 11, a bracket 12 is swingably connected front and back, and a telescopic rod 15 for controlling the swing of the bracket 12 is provided. The bracket 12 is used to horizontally support the stacked trays 2, and a lifting mechanism 13 for lifting the trays 2 is provided thereon. The swing setting structure of the bracket 12 has the advantage of facilitating docking with a number of stacked trays 2. That is to say, when the bracket 12 swings outwards to the extreme position, this position is the loading position; when the bracket 12 swings downwards to the extreme position, this position is the position for stably lifting the stacked trays 2, which is convenient for subsequently separately extracting a single tray 2.

[0040] Specifically, the bracket 12 includes two channel-shaped hanging brackets 121 and a horizontal positioning carrier plate 122. The two channel-shaped hanging brackets 121 are distributed front and back, and the free ends of both are hinged to the bottom of the frame platform 11. The horizontal positioning carrier plate 122 is rotationally and slidably connected to the opposite sides inside the two channel-shaped hanging brackets 121. The two channel-shaped hanging brackets 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 channel-shaped hanging brackets 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 tray 2. Specifically, when implementing, jacks for inserting the legs of the tray 2 can be opened on the top of the horizontal positioning carrier plate 122. The telescopic rod 15 is an electric push rod, and the number of telescopic rods 15 is two. One end of the telescopic rod 15 is hinged to the bottom of the frame platform 11 at one end, and the other end of the telescopic rod 15 is hinged to one side of the adjacent channel-shaped hanging bracket 121. The telescopic rod 15 is used to control the swing of the channel-shaped hanging bracket 121.

[0041] Furthermore, a suspension plate 111 fixedly connected to the bottom of the frame platform 11 and hinged to the free end of the channel-shaped hanging bracket 121 is provided. The lifting mechanism 13 includes a lifting lead screw 131, a transmission shaft 132, a bevel gear set 134, and a control assembly 133. Slideways 1211 are opened on both sides inside the channel-shaped hanging bracket 121. Sliders 1221 rotationally connected to both sides of the horizontal positioning carrier plate 122 and slidably matched with the slideways 1211 are provided. A lifting lead screw 131 rotationally connected inside the slideway 1211 and threadedly engaged with the slider 1221 is provided. A transmission shaft 132 is provided at the bottom of the channel-shaped hanging bracket 121, and the transmission shaft 132 is connected to the lifting lead screw 131 through the bevel gear set 134. Two transmission shafts 132 are correspondingly installed at the bottom of one channel-shaped hanging bracket 121. The bevel gear set 134 includes two meshing bevel gears. The control assembly 133 is used to control the rotation of the transmission shaft 132. When the lifting lead screws 131 on the two channel-shaped hanging brackets 121 rotate synchronously and in the same direction, the horizontal positioning carrier plate 122 will be driven to move horizontally up and down as a whole.

[0042] Among them, the preferred structure of the control assembly 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-shaped hanger 121 is rotatably connected to a transmission shaft 132. One end of the transmission shaft 132 is fixedly connected to a transmission pulley 1332. One side of the suspension plate 111 is rotatably connected to a transmission pulley 1332 coaxial with the swing axis of the trough-shaped hanger 121. The transmission pulleys 1332 on the same side are connected by a transmission belt 1331. When the transmission belt 1331 operates, it will drive the transmission shafts 132 at the bottom of the two trough-shaped hangers 121 to rotate synchronously and in the same direction through the transmission pulleys 1332. A control motor 1333 is fixedly connected between two adjacent suspension plates 111 through a support plate. The output shaft of the control motor 1333 is fixedly connected to a driving pulley 13331 that engages with the transmission belt 1331. That is to say, 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 swingably connected back and forth in the frame platform 11. The position where the extraction mechanism 14 is connected to the frame platform 11 is behind the trough-shaped hanger 121. The extraction mechanism 14 has the function of extracting the uppermost tray 2 one by one from the stacked trays 2. The extraction mechanism 14 disassembles and lifts the uppermost tray 2 to the transfer height. At this time, it is convenient for the external XYZ-axis manipulator to pick up the remote control circuit board from the tray 2 held by the extraction mechanism 14 and then place it on the assembly positioning fixture. Specifically, when implementing, a plurality of manipulator mounting platforms can be fixedly connected to the top of the frame platform 11. The manipulator mounting platform is connected to the XYZ-axis manipulator by bolts, and then a fixture for assembly positioning (not shown in the figure) is installed on the top of the frame platform 11.

[0044] Specifically, two supporting blocks 22 are fixedly connected to both sides of the tray 2 respectively. That is to say, two supporting blocks 22 are provided on both sides of one tray 2. 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 backing plate 143 and a drive group 144. One parallel hinge four-bar mechanism 141 is connected to both sides inside the frame platform 11. The bottom of the upper cross beam 1411 on the two parallel hinge four-bar mechanisms 141 is rotatably connected to the backing plate 143 up and down. Specifically, in implementation, ear plates can be welded to the bottom of the upper cross beam 1411 near both ends, and then support shafts rotatably connected to the ear plates are welded to both ends of the backing plate 143. The function of the backing plate 143 is to lift the supporting block 22. The relative side of the backing plate 143 and the adjacent upper cross beam 1411 is hinged and connected by the elastic telescopic pull rod 142. This setting makes the backing plate 143 swing upward when an upward thrust is applied to the bottom of the backing plate 143, and at the same time, the elastic telescopic pull rod 142 will be compressed. The elastic telescopic pull rod 142 adopts a common connecting and telescopic structure with an internal support spring. Thus, when the backing plate 143 moves above the tray 2 and then swings downward and touches the supporting block 22, it will swing upward. When it passes over the supporting block 22, the backing plate 143 will reset to the horizontal state under the push of the elastic telescopic pull rod 142. Then, when controlling the upper swing of the parallel hinge four-bar mechanism 141, the backing plate 143 will lift the entire tray 2 through the supporting block 22 to the working position for the external XYZ-direction manipulator to pick up. In this embodiment, the highest position of the tray 2 is the working position for the XYZ-direction manipulator to pick up and place each circuit board in the placement groove 21. The drive group 144 is used to control the synchronous swing of the two parallel hinge four-bar mechanisms 141.

[0045] Specifically, the drive group 144 includes a rack 1441, a drive motor 1442 and a transmission gear 1443. Two positioning plates 112 are fixedly connected to positions near both sides at the bottom of the frame platform 11. The free ends of the two support arms 1412 on the parallel hinge four-bar mechanism 141 are fixedly connected to a positioning shaft 14121 rotatably connected to the positioning plate 112. One end of the positioning shaft 14121 is fixedly connected to the transmission gear 1443. A horizontally distributed rack 1441 meshing with the transmission gear 1443 is slidably connected to one side of the adjacent two positioning plates 112. A drive motor 1442 is fixedly connected to positions near both sides at the bottom of the frame platform 11. The output shaft of the drive motor 1442 is fixedly connected to a driving gear 14421 meshing with the adjacent rack 1441. When the drive 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 to say, after the remote control circuit board in the current tray 2 is completely extracted, the extraction mechanism 14 can release the current empty tray 2, thereby improving the separation efficiency of the stacked trays 2 and further greatly improving the subsequent assembly efficiency of the remote control circuit board.

[0047] Specifically, positioning notches 14111 are provided on one side of the upper cross beam 1411 near both ends. The positioning notches 14111 are used in cooperation with the supporting blocks 22. A gate plate 1431 is slidably connected to the bottom of the backing plate 143. That is to say, when the backing plate 143 holds up the supporting block 22, the supporting block 22 will enter the positioning notch 14111, and the gate plate 1431 can prevent the supporting block 22 from leaking out of the positioning notch 14111. This setting has the advantages of improving the lifting accuracy and stability of the tray 2. A release notch 14311 is provided on one side of the gate plate 1431 near the positioning notch 14111. When the release notch 14311 coincides with the positioning notch 14111 when the gate plate 1431 slides, the supporting block 22 will directly disengage from the positioning notch 14111. At this time, the entire tray 2 will fall by its own weight. Thus, the extraction mechanism 14 can continue to lift the next tray 2 located at the top.

[0048] In this embodiment, support plates 1432 are fixedly connected to the bottom of the backing plate 143 near both ends. Guide shafts 14312 passing through the support plates 1432 are fixedly connected to both ends of the gate plate 1431. A return spring 1433 is sleeved on the guide shaft 14312 near the lifting mechanism 13 and is located between the backing plate 143 and the adjacent support plate 1432. Under the action of the return spring 1433, the positioning notch 14111 is in a state blocked by the gate plate 1431. Trigger plates 113 used in cooperation with the guide shafts 14312 are fixedly connected to both sides inside the frame platform 11. When the parallel hinge four-bar mechanism 141 swings towards the direction away from 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 coincides with the positioning notch 14111, the current tray 2 will be separated, which has the advantage of more convenient and faster control of releasing the tray 2.

[0049] Working principle: When in use, first control the telescopic rod 15 to contract, and the trough-shaped hanging bracket 121 swings upward to a position at one end of the frame platform 11. At this time, the operator can place a stack of trays 2 on the horizontal positioning carrier plate 122. Then control the telescopic rod 15 to reset to the position where the horizontal positioning carrier plate 122 is at the lowest. Start the control motor 1333, and the driving pulley 13331 drives the transmission belt 1331 to operate. At this time, all the transmission belt pulleys 1332 rotate synchronously in the same direction. Driven by the bevel gear set 134, the lifting lead screw 131 rotates to drive the horizontal positioning carrier plate 122 to rise horizontally. When the tray 2 at the highest position approaches the frame platform 11, control the driving motor 1442 to start. The driving gear 14421 drives the rack 1441 to slide. Driven by the transmission gear 1443, the entire parallel hinge four-bar mechanism 141 swings towards the tray 2. When the cushion plate 143 swings downward and touches the support block 22, it will swing upward. After it passes over the support block 22, under the push of the elastic telescopic pull rod 142, the cushion plate 143 will reset to the horizontal state. Then when controlling the parallel hinge four-bar mechanism 141 to swing upward, the cushion plate 143 will lift the entire tray 2 through the support block 22 to the working position for the external XYZ-direction manipulator to pick up. During this process, the support block 22 will enter the positioning notch 14111 and be limited by the gate plate 1431. Then start the XYZ-direction manipulator to pick up 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 picked up, control the parallel hinge four-bar mechanism 141 to continue swinging. When the parallel hinge four-bar mechanism 141 swings towards the 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, the current tray 2 will be separated, realizing the rapid release of the empty tray 2. Then control the parallel hinge four-bar mechanism 141 to reset and continue to pick up the next tray 2 at the highest position.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
