Description

Technical Field

[0001] This utility model relates to a bidirectional floating induction triggering device, belonging to the technical field of bidirectional limiting of material conveying. Background Technology

[0002] In industrial production processes, there are often application requirements such as material pushing or pulling. When pushing or pulling materials, a linear drive source is used in conjunction with a picking mechanism.

[0003] Generally, after the material is pushed into or pulled back into position, its positional accuracy needs to be ensured. This is usually achieved using station sensing or hard limit switching. Station sensing typically uses a U-shaped sensor, which triggers control by monitoring the sensing end passing through its U-groove. This triggering control has a certain response time, resulting in some displacement error and failing to guarantee the accuracy of the material's position when it stops. Hard limit switching generally uses a design that combines a stop block and a pushing floating mechanism. When the material is pushed to contact the stop block, a reverse force is generated, which acts on the pushing floating mechanism, causing it to stop.

[0004] However, in traditional industrial production, propulsion or pullback is a selective operation, meaning there is rarely a need for bidirectional propulsion and pullback. When bidirectional operation occurs, it is necessary to ensure the stopping accuracy of the two workstations. Generally, workstation sensors for the two workstations are used. When stopping accuracy needs to be met, a bidirectional power control method is adopted, which requires setting stopping trigger mechanisms at both ends of the bidirectional power. This results in a relatively large and complex structure, high cost, and is not conducive to application. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model.

It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0030] This invention provides a bidirectional floating induction triggering device, such as... Figures 1 to 6 As shown, it includes a linear guide body 1, an active mechanism 2 and a driven mechanism 3 that are slidably connected to the linear guide body 1, and a bidirectional floating trigger mechanism 4 disposed between the active mechanism and the driven mechanism.

[0031] The driven mechanism 3 includes a driven slide 31, and a material picking part 32 is provided on the side of the driven slide 31 away from the driving mechanism.

[0032] The active mechanism 2 includes an active slide 21 and a drive source 22 disposed on the active slide 21 for driving the active slide to linearly reciprocate on the rail body 1.

[0033] The bidirectional floating trigger mechanism 4 includes a floating carrier plate 41 disposed on the driven slide and a controller 42 communicatively connected to the drive source, and at least one slide rod 43 disposed on the active slide and passing through the floating carrier plate. The slide rod 43 is provided with a first elastic body 431 located between the active slide and the floating carrier plate, and a second elastic body 432 located between the floating carrier plate and the free end of the slide rod. The controller 42 has a first trigger end 421 facing the active mechanism and a second trigger end 422 facing the material picking part. The active slide 21 is provided with a first touch body 210 disposed opposite to the first trigger end, and the free end of the slide rod 43 is provided with a second touch body 430 disposed opposite to the second trigger end.

[0034] Detailed implementation process and principle explanation:

[0035] This bidirectional floating induction triggering device can be used in various bidirectional positioning work scenarios, such as bidirectional machining stations, bidirectional assembly stations, and loading / unloading stations.

[0036] During operation, after the material picking unit 32 picks up the material, the drive source 22 drives the active slide 21 to perform linear displacement on the rail body 1.

[0037] The drive is implemented by the active mechanism 2. After the active mechanism 2 moves relative to the driven mechanism 3, it generates a pushing force on the floating carrier plate 41 through the first elastic body 431. When the driven mechanism 3 is blocked and positioned on site, the first elastic body 431 undergoes elastic deformation, and the first touch body 210 abuts against the first trigger end 421. At this time, the controller 42 triggers the stop control of the drive source 22, thus realizing the stop control after positioning.

[0038] After the active mechanism 2 moves away from the driven mechanism 3 and generates a relative displacement, the second elastic body 432 generates a traction force on the driven mechanism 3. When the driven mechanism 3 is blocked and positioned on site, the second elastic body 432 is elastically compressed. At this time, the second trigger end 422 comes into contact with the second touch body 430. At this time, the controller 42 triggers the shutdown control of the drive source 22, thus realizing the shutdown control after positioning.

[0039] This design satisfies the requirement of stopping the driven mechanism 3 after it is driven in both directions, thus ensuring reliable and stable operation and protecting the drive source 22 from hard stopping.

[0040] In one specific embodiment, the active slide 2 is provided with two parallel slide rods 43, the free ends of the two slide rods are connected to a trigger carrier plate 5, and the second touch body is disposed on the trigger carrier plate.

[0041] The design of the double slide bar 43 meets the requirements of elastic guidance and stability, and also meets the requirements of mounting the trigger carrier plate 5. The trigger carrier plate 5 can increase the structural strength and achieve reliable and stable mounting of the second touch body.

[0042] In one specific embodiment, the linear guide body 1 includes a linear guide carrier 11, two parallel slide rails 12 disposed on the linear guide carrier 11, and a toothed rack 13 disposed on the linear guide carrier.

[0043] The drive source 22 includes a rotary power unit 221, which is provided with meshing transmission teeth 222 that mesh with and are engaged with the gear rack.

[0044] That is, the active slide 2 is slidably connected to the rail carrier 11 to achieve linear guiding sliding connection. During linear displacement control, the rotary power unit 221 drives the meshing transmission teeth 222 to rotate on the tooth row 13 to generate relative displacement, thereby driving the displacement of the active slide 2.

[0045] It should be noted that when the controller 42 generates a stop signal, there is a certain interaction force between the meshing transmission gear 222 and the gear row 13, which ensures the stability of the relative position of the active mechanism.

[0046] Of course, the drive source 22 is one embodiment of this case. Linear drive sources such as screw drive, telescopic cylinder, and telescopic hydraulic cylinder can also be used. Any mechanism that can meet the requirements of linear displacement drive and can achieve signal stop is within the protection scope of this case.

[0047] In one specific embodiment, the drive end of the rotary power unit 221 is connected to a gearbox body, and the meshing transmission teeth are arranged on the torque output end of the gearbox body.

[0048] This allows for a certain speed ratio adjustment, meeting the requirements for drive stability and stop position accuracy.

[0049] In one specific embodiment, the material picking unit includes one of a clamping mechanism, a magnetic adsorption mechanism, and a negative pressure adsorption mechanism.

[0050] Any picking mechanism that requires a linear force on the material to be greater than the relative or opposing floating pressure between the driven and driving mechanisms is within the scope of protection of this case.

[0051] This ensures that the material will not detach when subjected to the opposing force of elastic floating.

[0052] In one specific embodiment, the material picking unit 32 has a lifting displacement.

[0053] Specifically, during assembly, processing, cutting, loading and unloading operations, the vertical position of the workstation can be adjusted by the lifting displacement of its material picking unit 32, thus making its application more widespread.

[0054] In addition, in some rail conveying systems, there is also a need for cooperation between the loading and unloading of large materials. The lifting and lowering mechanism can be used to achieve downward avoidance, making its application very flexible.

[0055] As described above, this invention enables bidirectional floating stop after material pickup, achieving shutdown control of the drive source. Both directions are buffered by floating, eliminating the possibility of hard stoppage. The floating trigger mechanism between the driven and driving mechanisms is ingeniously designed, and the transmission coordination structure is compact and sophisticated. It meets various bidirectional stopping scenarios, offering wide applicability and flexibility.

[0057] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
