Abstract
Description
Technical Field
[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) trolley parts technology, and more specifically, it relates to a pallet positioning detection device. Background Technology
[0002] When an AGV (Automated Guided Vehicle) picks up a pallet and places it onto the AGV, it may fail to accurately identify the pallet's position on the AGV. This can lead to over-picking, causing the pallet to collide with the AGV and resulting in wear, or under-picking, causing the pallet to separate from the AGV during transport and resulting in personal injury or property damage. Traditional AGVs use electronic detection mechanisms for judgment and estimation, but in practice, this requires modifying the existing AGV structure to accommodate the detection mechanism, leading to a significant increase in cost and low adaptability. To address this, a pallet positioning detection device is proposed. This device has a simple structure, strong installation adaptability, and can be added to existing AGVs, making it highly adaptable to various scenarios. Utility Model Content

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] This utility model provides a pallet positioning detection device, such as... Figure 1 As shown, the device includes: a device body 1; the device body 1 is provided with: a trigger component 2 for contacting a tray and generating a stroke change, a detection component 3 for detecting the stroke change of the trigger component 2 and issuing a detection signal, and a reset component 4 for resetting the stroke of the trigger component 2; the trigger component 2 is rotatably connected to the device body 1; the detection component 3 is detachably connected to the device body 1, and the detection end of the detection component 3 is on the same horizontal line as the trigger component 2; one end of the reset component 4 is detachably connected to the device body 1, and the other end of the reset component 4 can abut against the trigger component 2.
[0024] Specifically, in practical applications, the device body 1 can be installed at the pallet fork position of the AGV trolley 5, such as... Figure 5 As shown, the preferred embodiment is inside the end of the fork arm placement slot; when the AGV trolley 5 picks up the pallet, when the pallet approaches the appropriate position, it will contact the trigger component 2, causing the trigger component 2 to start to change its stroke. The detection component 3 detects the stroke change of the trigger component 2, thereby determining whether the pallet is in the correct position; after one detection process is completed, the reset component 4 will reset the trigger component 2 to facilitate the next detection process.
[0025] Furthermore, the triggering component 2 includes: two adapters 21 and a trigger flap 22; one of the adapters 21 is rotatably disposed on one end of the device body 1, and the other adapter 21 is rotatably disposed on the other end of the device body 1; one end of the trigger flap 22 is rotatably connected to one of the adapters 21, and the other end of the trigger flap 22 is rotatably connected to the other adapter 21.
[0026] In Example 1, as Figure 1 As shown, in the initial state, the trigger flap 22 is at a certain angle deviation from the device body 1. When the tray comes into contact with the trigger flap, it will drive the trigger flap 22 to rotate toward the device body 1 with the adapters 21 on both sides as the center. This part of the rotation distance is the stroke change of the trigger flap 22.
[0027] Specifically, the adapter 21 is a rotating shaft composed of stepped bolts, which allows the trigger flipper to rotate at a certain angle.
[0028] Furthermore, the reset assembly 4 includes: a plurality of spring reset members 41; one end of the spring reset member 41 is detachably connected to the device body 1, and the other end can abut against the trigger flap 22.
[0029] In Example 2, as Figure 2-3 As shown, after one detection process is completed, the tray separates from the trigger flap 22. Several spring reset pieces 41 set on the device body 1 use their own elasticity to reset the trigger flap 22 to the initial state, so as to facilitate the next detection process.
[0030] Further, the spring reset component 41 includes: a reset cylinder 411, a reset spring 412, and a reset pin 413; the reset cylinder 411 is detachably connected to the device body 1; a spring groove 414 is provided inside the reset cylinder 411; a through hole 415 is provided at one end of the reset cylinder 411 away from the device body 1; the through hole 415 communicates with the spring groove 414; the reset spring 412 is housed in the spring groove 414; one end of the reset pin 413 passes through the through hole 415 and abuts against the reset spring 412; one end of the reset pin 413 located in the spring groove 414 can slide within the spring groove 414; the other end of the reset pin 413 can abut against the trigger flap 22.
[0031] In Example 3, as Figure 4 As shown, the tray triggers the trigger flap 22, which in turn triggers the reset pin 413. This causes the reset pin 413 to press the reset spring 412 toward the inside of the spring groove 414, so that the reset spring 412 is in a compressed state. When the tray separates from the trigger flap 22, the reset spring 412 in the spring groove 414 releases the compressed elastic force, causing the reset pin 413 to move toward the through hole 415, thereby driving the trigger flap 22 to reset to the initial state.
[0032] Furthermore, a first locking block 416 is provided on one end of the spring groove 414 near the through hole 415; a second locking block 417 is provided on one end of the reset pin 413 placed in the spring groove 414 to cooperate with the first locking block 416 to prevent the reset pin 413 from disengaging from the reset cylinder 411; the first locking block 416 and the second locking block 417 can abut against each other.
[0033] In Example 4, as Figure 3-4 As shown, the snap-fit structure of the second snap-fit block 417 on the reset pin 413 and the first snap-fit block 416 in the spring groove 414 prevents the reset spring 412 from squeezing the reset pin 413 out of the spring groove 414 in the initial state, thus preventing it from working properly.
[0034] Furthermore, the detection component 3 includes: a mounting plate 31 and a travel detection switch 32 for detecting changes in the travel of the trigger component 2; the mounting plate 31 is detachably connected to the device body 1, and the travel detection switch 32 is detachably connected to the mounting plate 31; the detection end of the travel detection switch 32 is at the same horizontal line as the trigger flap 22.
[0035] In Example 5, as Figure 1-2 As shown, the travel detection switch 32 is mounted on the device body 1 via the mounting plate 31. The detection end of the travel detection switch 32 faces the trigger flap 22 to detect the travel change of the trigger flap 22, thereby obtaining a signal as to whether the pallet has been forked into place.
[0036] Furthermore, the device body 1 includes: a fixing plate 11 and a support frame 12; the fixing plate 11 and the support frame 12 are detachably connected; the triggering component 2, the reset component 4 and the detection component 3 are all disposed on the support frame 12.
[0037] In Example 6, as Figure 1 and Figure 5 As shown, the support frame 12 can be quickly installed on the original AGV trolley 5 through the mounting plate 31, avoiding major modifications to the structure of the AGV trolley 5, and also enabling the original AGV trolley 5 to have the function of pallet positioning detection.
[0038] This utility model discloses a pallet positioning detection device. The device body 1 is small and easy to install. It can be installed on an existing AGV trolley 5 that lacks a pallet detection mechanism. By triggering the pallet and the trigger component 2, the detection component 3 detects the change in stroke after the trigger component 2 contacts the pallet, thereby detecting whether the pallet has been picked up by the forklift. The structure is simple and the recognition effect is accurate.
[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
