Description

Technical Field

[0001] This application relates to the field of switch manufacturing technology, and in particular to an assembly device for a switch button and cover plate. Background Technology

[0002] A switch is a simple and widely used control device. In electrical automatic control circuits, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc.

[0003] The switch includes a switch housing, a button, and a cover plate. During assembly, the button, cover plate, and spring are installed onto the switch housing in sequence and then tightened by riveting to complete the assembly of the switch.

[0004] Regarding the aforementioned technologies, the inventors believe that the traditional switch assembly process mainly involves manual material loading and then manual assembly of the components. This manual assembly method is not only labor-intensive but also has low production efficiency. Summary of the Invention

[0005] To replace manual loading and assembly of switches, this application provides an assembly device for switch buttons and covers.

[0006] The assembly equipment for a switch button and a cover plate provided in this application adopts the following technical solution: An assembly device for a switch button and a cover plate includes a base, on which a rotating worktable, a material transfer mechanism, a button feeding mechanism, a spring screening tray, a cover plate screening tray, a first suction component, and a mounting base are arranged. The cover plate screening tray includes a screening tray body, a feeding plate, and a feeding track. The feeding plate is located adjacent to the feeding track, and the first suction component is located above the feeding plate. The mounting base is provided with a transmission mechanism for driving the feeding plate to swing. The transmission mechanism includes a bearing seat, in which a rotating shaft is rotatably connected. A connecting piece is provided between the end of the rotating shaft facing the feeding plate and the feeding plate. A swing block is mounted on the end of the rotating shaft away from the feeding plate. A transmission block is hinged to the swing block. A drive cylinder is connected to the bottom of the transmission block facing the base. The bearing seat is provided with a mounting plate for mounting the drive cylinder.

[0007] By adopting the above technical solution, the feeding plate is tilted towards the screening disc body before the cover plate is placed, which further facilitates the material to be collected after the feeding track transfers the material to the feeding plate. When the cover plate is placed on the feeding plate, the drive cylinder drives the swing block to swing through the transmission block. The swing block further drives the rotating shaft to rotate in the bearing seat, thereby causing the feeding plate connected to the rotating shaft through the connector to flip over until it is parallel to the horizontal end face of the feeding track. This further facilitates the first receiving component above the feeding plate to receive the cover plate on the feeding plate and quickly transfer the cover plate to the next assembly step, greatly improving the production efficiency of switch assembly.

[0008] Optionally, the connector includes a connecting seat disposed on the rotating shaft, a connecting clamp plate integrally formed on the connecting seat, a groove for mounting a feeding plate being formed on the connecting clamp plate, and the feeding plate and the connecting clamp plate being threadedly connected.

[0009] By adopting the above technical solution, the side of the feeding plate near the connecting seat is inserted into the groove of the connecting clamp plate and then fixed by threaded connection. The connection method is simple and the feeding plate is easy to disassemble.

[0010] Optionally, the base is provided with a first mounting bracket, the first mounting bracket is provided with a first guide seat, the first guide seat is provided with a first sliding guide rod, the first sliding seat is slidably provided with a first sliding block, and the first guide seat is provided with a first horizontal driving member that cooperates to drive the first sliding block to slide along the first sliding guide rod. The first sliding block is equipped with a first lifting driving member, and the first suction assembly is provided on the first lifting driving member.

[0011] By adopting the above technical solution, the first horizontal drive unit drives the first sliding seat to slide along the first sliding guide rod until the first lifting drive unit on the first sliding seat moves to above the loading plate. The first lifting drive unit drives the first suction component to descend towards the loading plate. The first suction component sucks up the cover plate of the loading plate. After the suction is completed, the first suction component is reset and continues to drive the first sliding seat to move towards the rotating worktable. Finally, the cover plate is transferred to the rotating worktable to wait for assembly with the switch.

[0012] Optionally, the first suction assembly includes a mounting base disposed on the first lifting drive component, and a first vacuum suction head unit is connected to the bottom of the mounting base facing the material unloading plate.

[0013] By adopting the above technical solution, the first vacuum suction head unit is mounted on the first lifting drive unit through the mounting base. The material suction work of the cover plate is mainly carried out by the first vacuum suction head unit, which further replaces manual feeding, thereby reducing manpower and reducing production costs.

[0014] Optionally, the button feeding mechanism includes a support base, a button feeding plate, and a second suction assembly. The support base is disposed on the end face of the base, and the button feeding plate is placed on the support base.

[0015] By adopting the above technical solution, the support base is located on the adjacent side of the rotating worktable, and the button is placed on the button feeding plate. The button is mainly fed to the rotating worktable by the second suction component, which makes the button feeding more automated and further cooperates with the switch for rapid assembly.

[0016] Optionally, the second suction assembly includes a second mounting bracket, a second guide seat is provided on the second mounting bracket, a second sliding guide rod is provided on the second guide seat, a second sliding seat is slidably provided on the second sliding guide rod, a second horizontal drive member is provided on the second guide seat to drive the second sliding seat to slide along the second sliding guide rod, a second lifting drive member is provided on the second sliding seat, and a second vacuum suction head unit is provided at the bottom of the second lifting drive member toward the button feeding plate.

[0017] By adopting the above technical solution, the second horizontal drive unit drives the second sliding seat to slide along the second sliding guide rod until the second lifting drive unit on the second sliding seat moves to above the button feeding plate. The second lifting drive unit drives the second vacuum suction head unit to descend towards the feeding plate. The second vacuum suction head unit sucks up the button on the button feeding plate, then resets the second vacuum suction head unit and continues to drive the second sliding seat to move towards the rotating worktable. Finally, the second lifting drive unit transfers the button to the rotating table to wait for assembly with the switch. The button's suction and transfer method is the same as that of the cover plate, which is very convenient.

[0018] Optionally, a sliding placement plate is slidably provided on the end face of the support base, and the button feeding plate is placed on the sliding placement plate.

[0019] By adopting the above technical solution, the sliding placement plate is set at the bottom of the button feeding plate facing the support base. The button feeding plate can slide along the support base through the sliding placement plate, and further cooperate with the second vacuum suction head unit to suck up the material, thereby improving the feeding efficiency of the button.

[0020] Optionally, the base end face is provided with a mounting frame, the mounting frame is provided with a rotation drive component, the rotating worktable is provided on the rotation drive component, and the rotating worktable is provided with four material feeding seats with the same structure.

[0021] By adopting the above technical solution, the switch is mainly placed on the feeding seat of the rotating worktable. The rotating worktable rotates by the rotating drive component on the mounting frame. The rotating worktable rotates only 45 degrees at a time. Each rotation first rotates the feeding seat to the position where the second vacuum suction head unit is waiting to unload the material. After placing the button, the worktable rotates another 45 degrees, and the feeding seat with the button placed rotates to the position where the first vacuum suction head unit is waiting to unload the material. It waits for the first vacuum suction head unit to unload the cover plate onto the feeding seat. Then, the button and cover plate are assembled onto the switch. The placement of the switch, the button, and the cover plate are all very orderly, making the switch assembly process smoother.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. After the cover plate is placed on the loading plate, the drive cylinder drives the swing block to swing through the transmission block. The swing block further drives the rotating shaft to rotate in the bearing seat, thereby causing the loading plate connected to the rotating shaft through the connector to flip over until it is parallel to the horizontal end face of the loading track. Then, the cover plate on the loading plate is collected by the first receiving component, and the cover plate is quickly transferred to the next assembly step, which greatly improves the production efficiency of switch assembly.

[0023] 2. The material suction of the cover plate on the feeding plate is mainly carried out by the first suction component. The button is mainly placed on the button feeding plate. The button is mainly suctioned to the rotating worktable by the second suction component, which further replaces manual feeding, thereby reducing manpower and reducing production costs.

[0024] 3. The switch is mainly placed on the feeding seat of the rotating worktable. The rotating worktable rotates by the rotating drive component on the mounting frame. The rotating worktable rotates only 45 degrees at a time. Each rotation first rotates the feeding seat to the position where the second vacuum suction head unit is waiting to unload the material. After placing the button, the worktable rotates another 45 degrees, and the feeding seat with the button placed is rotated to the position where the first vacuum suction head unit is waiting to unload the material. It waits for the first vacuum suction head unit to unload the cover plate onto the feeding seat. Then, the button and cover plate are assembled onto the switch. The placement of the switch, the button, and the cover plate are all very orderly, making the switch assembly process smoother. Attached Figure Description

The mounting base 5 is threadedly connected to the base 34 and has a transmission mechanism threadedly connected to the feeding plate 32. The transmission mechanism includes a bearing seat 6 integrally formed with the mounting base 5. A rotating shaft 7 is rotatably connected inside the bearing seat 6. A connecting piece 8 is threadedly connected between the end of the rotating shaft 7 facing the feeding plate 32 and the feeding plate 32. A swing block 9 is integrally formed on the end of the rotating shaft 7 away from the feeding plate 32. A transmission block 10 is hinged to the swing block 9. A drive block 10 is coaxially connected to the side of the transmission block 10 facing the base 34 and away from the swing block 9. The drive cylinder 11 is threadedly connected to the bearing seat 6, and a mounting plate 12 is used to fix the drive cylinder 11. There is a gap between the feeding plate 32 and the feeding track 33. The size of this gap does not affect the feeding of the cover plate, and further facilitates the flipping of the feeding plate 32. Before the cover plate is placed, the feeding plate 32 is tilted towards the screening disc body 31, which further facilitates the collection of the material after the feeding track 33 transmits the material to the feeding plate 32. When the cover plate is transmitted to the feeding plate 32 through the feeding track 33 on the screening disc body 31, the drive cylinder 11 is opened. The drive cylinder 11 drives the swing block 9 to swing through the transmission block 10. The swing block 9 further drives the rotating shaft 7 to rotate in the bearing seat 6, thereby driving the feeding plate 32, which is connected to the rotating shaft 7 through the connecting piece 8, to flip. The flipped plate is parallel to the horizontal end face of the feeding track 33. Then, the first receiving component collects the cover plate on the feeding plate 32 and quickly transmits the cover plate to the next assembly step, which greatly improves the production efficiency of switch assembly.

In the lifting operation, the first suction assembly 4 includes a mounting base 19 threadedly connected to the first lifting drive 18. The bottom of the mounting base 19 facing the lower plate has an integrally formed first vacuum suction head unit 20. After the screened cover plate is placed on the upper plate 32, the first horizontal drive 17 drives the first sliding seat 16 to slide along the first sliding guide rod 15 until the first lifting drive 18 on the first sliding seat 16 moves above the upper plate 32. The first lifting drive 18 drives the first suction assembly 4 to descend towards the upper plate 32. The first vacuum suction head unit 20 sucks up the cover plate of the upper plate 32. After the sucking is completed, the first suction assembly 4 is reset and the first sliding seat 16 continues to move towards the rotating worktable 1. Finally, the cover plate is transferred to the rotating worktable 1 to wait for assembly with the switch.

There is a second vacuum suction head unit 29. The second lifting drive component 28 in this application is a hydraulic cylinder in the prior art. The second vacuum suction head unit 29 performs lifting and lowering operations through the hydraulic cylinder. The second horizontal drive component 27 drives the second sliding seat 26 to slide along the second sliding guide rod 25 until the second lifting drive component 28 on the second sliding seat 26 moves to above the button feeding plate 22. The second lifting drive component 28 drives the second vacuum suction head unit 29 to descend towards the feeding plate 32. The second vacuum suction head unit 29 sucks up the button on the button feeding plate 22. After the sucking is completed, the second vacuum suction head unit 29 is reset and continues to drive the second sliding seat 26 to move towards the rotating worktable 1. Finally, the button is transferred to the rotating worktable 1 through the second lifting drive component 28 to wait for the cover plate to be placed and the switch to be assembled.

[0036] The support base 21 is threaded onto the end face of the base 34. A sliding placement plate 30 is slidably disposed on the end face of the support base 21.

The first vacuum suction head unit 20 unloads the cover plate onto the material feeding seat 33, and then the button and cover plate are assembled onto the switch. The placement of the switch, button, and cover plate is very orderly, making the switch assembly process smoother.

[0038] The implementation principle of the assembly equipment for a switch button and cover plate in this application embodiment is as follows: First, the switch is placed on the rotating worktable 1, and then the rotating drive 32 is turned on. The rotating worktable 1 rotates 45 degrees through the rotating drive 32 until the material feeding platform on the rotating worktable 1 rotates to the position where the button is to be placed. The second horizontal drive 27 drives the second sliding seat 26, and the second sliding seat 26 moves to the top of the button feeding plate 22. The second lifting drive 28 drives the second vacuum suction head unit 29 to descend towards the feeding plate 32.

The first lifting drive component 18 drives the first suction component 4 to descend towards the loading plate 32. The first vacuum suction head unit 20 sucks the cover plate of the loading plate 32. After the suction is completed, the first suction component 4 is reset and the first sliding seat 16 continues to move towards the rotating worktable 1. Finally, the cover plate is transferred to the rotating worktable 1 to wait for assembly with the switch.
