Description

TECHNICAL FIELD

[0001] The application relates to the technical field of forklift production, in particular to a spring assembling mechanism of a forklift switch assembling device. BACKGROUND

[0002] The forklift switch includes a forklift light switch and a forklift gear switch, and the forklift gear switch is used for switching gears.

[0003] In the related art, the forklift gear switch is internally provided with a gear operating rod and multiple sets of contact assemblies. Figure 1 As shown in a forklift gear switch, the forklift gear switch comprises a switch seat body 01 and a contact assembly 02. The switch seat body 01 is provided with four installation grooves 011, and one contact assembly 02 is arranged in each installation groove 011. The contact assembly 02 comprises a spring 021, a moving contact piece 022, a static contact piece 023 and a limiting piece 024. A conventional assembling mode is to sequentially embed the spring 021, the moving contact piece 022, the static contact piece 023 and the limiting piece 024 in the installation groove 011 and press them tightly, so that the moving contact piece 022 presses the spring 021 tightly. The groove bottom of the installation groove 011 is provided with two embedding grooves 012, and the two embedding grooves 012 are respectively located at two ends of the installation groove 011. The two springs 021 are respectively embedded in the two embedding grooves 012.

[0004] The existing full-automatic forklift switch assembling device comprises eight stations, i.e., switch seat feeding, spring assembling, moving contact piece assembling, static contact piece assembling, limiting piece assembling, pressing, detection and switch seat discharging. In order to facilitate the switch seat body to enter or leave the spring product station, a gap exists between the lower end of the discharging channel of the spring assembling mechanism of the spring assembling station and the switch seat body. When the spring leaves the spring assembling mechanism and enters the installation groove, the spring may be offset, which affects the assembling precision and production efficiency of the assembling device. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the assembling precision of the spring and the assembling precision and production efficiency of the assembling device, the application provides a spring assembling mechanism of a forklift switch assembling device.

[0006] The spring assembling mechanism of the forklift switch assembling device provided by the application adopts the following technical scheme:

[0007] A spring assembly mechanism for a forklift switch assembly device includes a frame, a spring feeding assembly, and a conveying assembly. The frame has a placement platform connected to its upper end, and the placement platform has a placement slot for placing switch base bodies. The conveying assembly includes a first drive cylinder and a discharge section. The discharge section is slidably connected to the frame, and the sliding direction of the discharge section is vertical. The discharge section has several discharge channels, and the number of discharge channels corresponds one-to-one with the number of slots in the switch base bodies. The first drive cylinder is connected to the frame and is used to drive the discharge section to slide. The spring feeding assembly is connected to the frame, and the discharge port of the spring feeding assembly is connected to the discharge channels via a pipe.

[0008] By adopting the above technical solution, when the switch seat body is embedded below the discharge section, the first drive cylinder drives the discharge section to move downward, which reduces the gap between the end of the discharge channel near the switch seat body and the switch seat body, making it easier for the spring to fall accurately into the groove of the switch seat body. The first drive cylinder drives the discharge section to move upward, which makes it easier to remove the switch seat body and put in the next switch seat body, improving the accuracy of spring assembly and improving the assembly precision and production efficiency of the assembly equipment.

[0009] Preferably, the conveying assembly further includes a feeding section, a connecting hose, a sliding seat, and a drive source. The feeding section is connected to the frame and has feeding channels. The number of feeding channels and connecting hoses is the same as the number of discharging channels and corresponds one-to-one. One end of the connecting hose is connected to the discharging section, and the other end of the connecting hose is connected to the feeding section. The connecting hose connects the discharging channel and the feeding channel. The sliding seat is slidably connected to the feeding section. The sliding direction of the sliding seat is horizontal. The sliding seat has temporary storage channels. There are two temporary storage channels, which are used to communicate with the feeding channels. The drive source is connected to the feeding section and is used to drive the sliding seat to slide.

[0010] By adopting the above technical solution, the drive source drives the sliding seat to slide, so that the two temporary storage channels are connected to the eight feeding channels in sequence. Then, the spring is transported to the discharge channel through the connecting hose to realize the spring assembly. This helps to reduce the number of spring feeding components connected to the temporary storage channels and reduce production costs.

[0011] Preferably, the conveying assembly further includes a first positioning post and a second positioning post. The number of the first positioning post and the second positioning post is the same as the number of temporary storage channels and they correspond one-to-one. A first positioning hole is provided on the inner wall of the temporary storage channel. The first positioning post is slidably embedded in the first positioning hole. The sliding direction of the first positioning post is perpendicular to the axial direction of the temporary storage channel. One end of the first positioning post is used to extend into the temporary storage channel. A second positioning hole is provided on the inner wall of the temporary storage channel. The second positioning hole is located above the first positioning hole. The second positioning post is slidably embedded in the second positioning hole. The sliding direction of the second positioning post is perpendicular to the axial direction of the temporary storage channel. One end of the second positioning post is used to extend into the temporary storage channel.

[0012] By adopting the above technical solution, after the spring enters the temporary storage channel, the second positioning post limits the spring. The second positioning post slides into the second positioning hole, and the limitation of the spring by the second positioning post disappears. The spring moves down and abuts against the first positioning post. The second positioning post is embedded in the temporary storage channel and limits the next spring. When the first positioning post is embedded in the first positioning hole, only one spring falls into the discharge channel through the connecting hose, which improves the assembly accuracy and reliability of the assembly equipment.

[0013] Preferably, the conveying assembly further includes a connecting seat and a second driving cylinder. The connecting seat is slidably connected to a sliding seat, and the sliding direction of the connecting seat is horizontal. The second driving cylinder is connected to the sliding seat and is used to drive the connecting seat to slide. The first positioning hole is located on the side of the temporary storage channel near the second driving cylinder, and the second positioning hole is located on the side of the temporary storage channel away from the first positioning hole. The sliding direction of the first positioning post and the second positioning post is parallel to the sliding direction of the connecting seat, and the ends of the first positioning post and the second positioning post away from the temporary storage channel are connected to the connecting seat.

[0014] By adopting the above technical solution, the connecting seat is slid by the second drive cylinder, which in turn drives the first positioning post and the second positioning post to slide. This allows the first positioning post to extend into the temporary storage channel when the second positioning post is embedded in the second positioning hole, reducing the possibility of errors caused by manual intervention and improving the automation level of the assembly equipment.

[0015] Preferably, an air blowing hole is provided on the inner wall of the temporary storage channel. The air blowing hole is located below the first positioning hole and is connected to the air outlet of the second drive cylinder through a pipe.

[0016] By adopting the above technical solution, when the second drive cylinder is working, gas is introduced into the temporary storage channel through the air blowing hole, which pushes the spring in the connecting hose into the discharge channel, reducing the possibility of the spring blocking the connecting hose and improving the production efficiency and reliability of the assembly equipment.

[0017] Preferably, the conveying assembly further includes a baffle, a pusher, and a reset member. The baffle is slidably connected to the discharge section, and the sliding direction of the baffle is horizontal. The reset member is connected between the discharge section and the baffle, and the reset member causes the baffle to tend to close the discharge channel. The pusher is slidably connected to the discharge section, and the sliding direction of the pusher is vertical. The lower end of the pusher is used to abut against the placement platform, and the upper end of the pusher is provided with a chamfer, which is used to abut against the baffle.

[0018] By adopting the above technical solution, when the spring assembly mechanism is not working, the baffle closes the discharge channel, reducing the possibility of external impurities entering the connecting hose through the discharge channel and keeping the connecting hose unobstructed. When the first drive cylinder pushes the discharge part down, the push block abuts against the placement table. The push block moves up and the chamfer abuts against the baffle, pushing the baffle to overcome the elasticity of the reset part and slide, so that the discharge channel is connected to the outside, making it easier for the spring to enter the groove of the switch seat body, thus improving the safety and reliability of the assembly equipment.

[0019] Preferably, the conveying assembly further includes sensors and a processor. The number of sensors is the same as the number of temporary storage channels and corresponds one-to-one. The sensors are connected to the sliding seat and are located below the first positioning hole. The sensors are used to detect whether a spring enters the connecting hose and send a signal to the processor. The processor is used to receive the signal and control the drive source to work.

[0020] By adopting the above technical solution, a sensor is set to detect whether a spring enters the connecting hose. If a spring enters the connecting hose in either of the two temporary storage channels, the processor sends a signal to control the drive source to work, causing the sliding seat to slide, so that the temporary storage channel is aligned with the next set of feeding channels, thereby improving the automation level of the assembly equipment.

[0021] Preferably, it further includes a turntable and a first drive motor. The turntable is rotatably connected to the frame, and the rotation axis of the turntable is vertical. The first drive motor is connected to the frame and is used to drive the turntable to rotate. The placement platform is connected to the turntable, and there are several placement platforms, which are circumferentially spaced around the rotation axis of the turntable.

[0022] By adopting the above technical solution, the first drive motor drives the turntable to rotate, and multiple placement platforms are circumferentially distributed around the rotation axis of the turntable, which facilitates the loading of switch base bodies, and the simultaneous assembly of springs and unloading of switch base bodies, thereby improving the production efficiency of the assembly equipment.

[0023] Preferably, it further includes a clamping assembly, which includes a slider and a third drive cylinder. The slider is slidably connected to the frame, and the sliding direction of the slider is perpendicular to the rotation axis of the turntable. The slider is used to abut against the side wall of the switch seat. The third drive cylinder is connected to the frame and is used to drive the slider to slide.

[0024] By adopting the above technical solution, the third drive cylinder drives the slider to slide and slide against the side wall of the switch seat body, reducing the possibility of the switch seat body moving horizontally during spring assembly, improving the accuracy of spring assembly, and improving the assembly precision and production efficiency of the assembly equipment.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When the switch seat body is embedded below the discharge section, the first drive cylinder drives the discharge section to move downward, which reduces the gap between the end of the discharge channel near the switch seat body and the switch seat body, making it easier for the spring to fall accurately into the groove of the switch seat body. The first drive cylinder drives the discharge section to move upward, which makes it easier to remove the switch seat body and put in the next switch seat body, improving the accuracy of spring assembly and improving the assembly precision and production efficiency of the assembly equipment.

[0027] 2. After the spring enters the temporary storage channel, the second positioning post limits the spring. The second positioning post slides into the second positioning hole. The limitation of the spring by the second positioning post disappears. The spring moves down and abuts against the first positioning post. The second positioning post is embedded in the temporary storage channel and limits the next spring. When the first positioning post is embedded in the first positioning hole, only one spring falls into the discharge channel through the connecting hose, which improves the assembly accuracy and reliability of the assembly equipment.

[0028] 3. When the spring assembly mechanism is not working, the baffle closes the discharge channel, reducing the possibility of external impurities entering the connecting hose through the discharge channel and keeping the connecting hose unobstructed. When the first drive cylinder pushes the discharge part down, the push block abuts against the placement table. The push block moves up and the chamfer abuts against the baffle, pushing the baffle to overcome the elasticity of the reset part and slide, so that the discharge channel is connected to the outside, making it easier for the spring to enter the groove of the switch seat body, thus improving the safety and reliability of the assembly equipment.

The processor is used to receive the signal and control the second drive motor 261 to work.

[0054] The implementation principle of the spring assembly mechanism of the forklift switch assembly equipment in this application embodiment is as follows: the first drive motor 14 drives the turntable 13 to rotate through the pulley 15 and the belt body 16, which drives the placement platform 12 with the switch seat body embedded to rotate to below the discharge section 22. The piston rod of the third drive cylinder 32 extends out, driving the slider 31 to slide through the connecting groove 122 and then abut against the switch seat body.

[0055] The temporary storage channel 2511 is connected to two feeding channels 231. The spring feeding assembly transports the spring to the temporary storage channel 2511 through a pipe. The second positioning post 210 is embedded in the temporary storage channel 2511, blocking the spring. The piston rod of the second drive cylinder 29 extends, causing the first positioning post 28 to slide into the temporary storage channel 2511, and the second positioning post 210 to slide into the second positioning hole 253. The spring falls and abuts against the first positioning post 28. The piston rod of the second drive cylinder 29 retracts, causing the second positioning post 210 to embed into the temporary storage channel 2511, thereby limiting the second spring above the first positioning post 28. The first positioning post 28 slides into the first positioning hole 252. The spring enters the connecting hose 24 from the upper connecting pipe 232, and then enters the discharge channel 221 through the lower connecting pipe 226. The baffle 211 closes the discharge channel 221, and the spring is located above the baffle 211. The second drive motor 261 operates, driving the drive disc 262 to rotate. This, via the connecting rod 263, causes the sliding seat 25 to slide, connecting the temporary storage channel 2511 to the other two feeding channels 231. The second drive cylinder 29 operates, conveying the next spring through the connecting hose 24 to the corresponding discharge channel 221. After conveying all eight springs, the first drive cylinder 21 operates, causing the discharge section 22 to move downwards, which in turn causes the push block 212 to move downwards. The push block 212 abuts against the upper end of the placement platform 12, pushing it upwards. The chamfer 2121 abuts against the baffle 211, pushing the baffle 211 to slide, connecting the connecting hole 2111 to the discharge channel 221. The discharge pipe 222 aligns with the groove in the switch seat body, and the spring is correspondingly embedded in the groove.

[0056] The piston rod of the first drive cylinder 21 retracts, causing the discharge section 22 to move upward. The reset component 213 pushes the baffle 211 to reset, so that the baffle 211 closes the discharge channel 221. The baffle 211 abuts against the chamfer 2121, pushing the push block 212 to move downward.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
