Description

Technical Field

[0001] The utility model relates to the field of automation equipment, in particular to an automatic untying device used for elastic straps. Background Art

[0002] After car seat production is complete, manufacturers need to ship the finished seats, packaging and securing them for subsequent transportation to customers. During this shipping process, shipping pallets are used as carriers. These pallets have cavities for accommodating the car seats and are secured with elastic straps to prevent them from shaking during transport. The elastic straps also provide excellent cushioning, securing the seats without causing impact or damage.

[0003] Currently, the car seat is usually placed on the shipping pallet first, and then an elastic strap with a buckle at the end is used (a corresponding clamping column structure is provided in the shipping pallet). The elastic strap is placed on the car seat, and the buckles at both ends are respectively fastened to the clamping columns at both ends of the pallet to tighten the elastic strap, thereby binding the car seat to the shipping pallet; after arriving at the delivery point, the production staff manually pulls the buckle at one end of the elastic strap from the clamping column, loosening the elastic strap so that the car seat can be taken out.

[0004] To ensure that the seats are well fixed during transportation, the elastic coefficient of the elastic straps used for loading is usually relatively high, which means that greater force is required when untying, which is very labor-intensive for the operator. In addition, the untying efficiency is low. Car seats are usually shipped in batches, and the untying process consumes a lot of time, which is not conducive to production efficiency.

[0011] Furthermore, the Y-axis driving mechanism further includes: a Y-axis cylinder mounting bracket; the Y-axis cylinder is fixedly arranged on the Y-axis cylinder mounting bracket.

[0012] Furthermore, the Y-axis drive mechanism also includes: a Y-axis slide rail and a Y-axis slider; the X-axis cylinder mounting plate is fixedly connected to the Y-axis slider, the Y-axis slider slides relative to the Y-axis slide rail, and the Y-axis slide rail is fixedly connected to the Y-axis cylinder mounting bracket.

[0013] Furthermore, the Z-axis drive mechanism includes: a Z-axis cylinder; the Z-axis cylinder is fixed on the main frame and arranged vertically, and the protruding end of the Z-axis cylinder is fixedly connected to the bottom or top of the Y-axis cylinder mounting frame.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0029] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] The utility model discloses a detent device for elastic straps, which is used to detent the car seat after transportation. Figure 2-Figure 3 During the unloading process, the car seat is placed on the unloading tray 70 and secured with an elastic strap 60. Specifically, a buckle 61 is provided at the end of the elastic strap 60, and correspondingly, a post 71 is provided inside the unloading tray 70. When securing the car seat, the buckle 61 of the elastic strap 60 engages with the post 71 of the unloading tray 70, keeping the car seat secure during transportation. After transportation, the car seat needs to be untied. At this time, the buckle 61 of the elastic strap 60 needs to be disengaged from the post 71 of the unloading tray 70, and finally, the elastic strap 60 is released. The function of this utility model is to achieve the above-mentioned unfastening process.

[0031] See Figure 1 、 Figure 4-Figure 6 The present invention includes: pneumatic fingers 10 for clamping the upper and lower sides of an elastic band 60; an X-axis drive mechanism 20 for driving the pneumatic fingers 10 in a linear motion along the X-axis; a Y-axis drive mechanism 30 for driving the pneumatic fingers 10 in a linear motion along the Y-axis; a Z-axis drive mechanism 40 for driving the pneumatic fingers 10 in a linear motion along the Z-axis; and a main frame 50. The X-axis drive mechanism 20, the Y-axis drive mechanism 30, and the Z-axis drive mechanism 40 together form a three-axis linkage mechanism that can drive the pneumatic fingers 10 to any position on the unloading tray 70.

[0032] Among them, the pneumatic finger 10 is arranged above the car seat unloading tray 70, and the buckle 61 of the elastic strap 60 is connected to the clamping column 71 of the unloading tray 70 to tighten the elastic strap 60; the X-axis drive mechanism 20, the Y-axis drive mechanism 30 and the Z-axis drive mechanism 40 cooperate to drive the pneumatic finger 10 to the position of the elastic strap 60. When the pneumatic finger 10 moves, the two clamps can clamp or loosen the elastic strap 60.

[0033] When the elastic strap 60 needs to be unfastened, the X-axis drive mechanism 20 drives the pneumatic finger 10 to move linearly along the horizontal X-axis direction, the Y-axis drive mechanism 30 drives the pneumatic finger 10 to move linearly along the horizontal Y-axis direction, and the Z-axis drive mechanism 40 drives the pneumatic finger 10 to move linearly along the vertical Z-axis direction. Through the coordinated movement of the three axes, the pneumatic finger 10 reaches the elastic band 60. The two clamping jaws are located on the upper and lower sides of the elastic band 60, respectively. The pneumatic finger 10 actuates, clamping the elastic band 60 with its two clamping jaws. Then, the Y-axis drive mechanism 30 actuates, driving the pneumatic finger 10 along the Y-axis. The pneumatic finger 10 clamps the elastic band 60, disengaging the buckle 61 on the elastic band 60 from the latch 71 on the outbound tray 70, thereby freeing one end of the elastic band 60 from the outbound tray 70. Since the elastic band 60 is already in a tensioned state, the pneumatic finger 10 releases, causing the elastic band 60 to elastically return to its original position and release the car seat from the outbound tray 70, completing the unfastening of the elastic band 60. The three-axis drive mechanism resets, waiting for the next unfastening action, and the cycle repeats.

[0034] The present invention realizes the unbuckling of the elastic strap 60 in an automated form. The pneumatic fingers 10 and the drive mechanism can ensure that the torque output during unbuckling is sufficient, and there is no need to consume a lot of physical strength of the operator as in the previous manual method. Moreover, the mechanism runs fast and has a high unbuckling efficiency, which is conducive to quickly unbuckling a large number of car seats, reducing the man-hours of manual unbuckling in the past, and is beneficial to production efficiency.

The X-axis cylinder 21 is fixed, the pneumatic finger connection block 22 is fixed to the extended end of the X-axis cylinder 21, and the pneumatic finger 10 is fixedly connected to the pneumatic finger connection block 22. When the X-axis cylinder 21 is output, the pneumatic finger connection block 22 drives the pneumatic finger 10 to move linearly along the X-axis direction.

[0036] More specifically, the X-axis driving mechanism 20 includes an X-axis cylinder mounting plate 23 for providing a mounting support position for the X-axis cylinder 21 ; the X-axis cylinder 21 is fixed on the X-axis cylinder mounting plate 23 .

[0037] Specifically, the Y-axis drive mechanism 30 includes a Y-axis cylinder 31 and a Y-axis cylinder adapter plate 32.

The output direction of the Y-axis cylinder 31 is perpendicular to the output direction of the X-axis cylinder 21 on a horizontal plane. When the Y-axis cylinder 31 is output, the Y-axis cylinder adapter plate 32 drives the X-axis cylinder mounting plate 23 to move along the Y-axis, thereby simultaneously driving the X-axis cylinder 21 and the pneumatic finger 10 along the Y-axis.

[0038] More specifically, the Y-axis driving mechanism 30 further includes a Y-axis cylinder mounting bracket 33 for providing a mounting support position for the Y-axis cylinder 31 ; the Y-axis cylinder 31 is fixedly mounted on the Y-axis cylinder mounting bracket 33 .

[0039] To enhance the guiding effect of sliding in the Y-axis direction, the Y-axis drive mechanism 30 preferably further includes a Y-axis slide rail 34 and a Y-axis slider 35. The X-axis cylinder mounting plate 23 is fixedly connected to the Y-axis slider 35. The Y-axis slider 35 and the Y-axis slide rail 34 are slidable relative to each other, and the Y-axis slide rail 34 is fixedly connected to the Y-axis cylinder mounting bracket 33. When the Y-axis cylinder 31 is output, the X-axis cylinder mounting plate 23 follows the Y-axis slider 35 and slides along the Y-axis slide rail 34.

[0040] Specifically, the Z-axis drive mechanism 40 includes a Z-axis cylinder 41, which is fixed to the main frame 50 and arranged vertically. The extended end of the Z-axis cylinder 41 is fixedly connected to the bottom or top of the Y-axis cylinder mounting bracket 33. When the Z-axis cylinder 41 is output, it drives the Y-axis cylinder mounting bracket 33 to move up and down along the Z-axis, thereby driving the Y-axis drive mechanism 30, the X-axis drive mechanism 20, and the pneumatic finger 10 to move up and down synchronously.

[0041] Preferably, the present invention can be equipped with two unbinding stations to achieve higher efficiency. Two Y-axis cylinders 31 with opposite output directions are arranged on the Y-axis cylinder mounting frame 33. The two Y-axis cylinders 31 are each connected to an X-axis drive mechanism 20. The two X-axis drive mechanisms 20 are located on either side of the Y-axis cylinder mounting frame 33.

[0042] In order to make the overall structure of the mechanism more compact, preferably, a Z-axis cylinder connecting plate 51 for installing the Z-axis cylinder 41 is provided on the top of the main frame 50, and the Y-axis cylinder mounting frame 33 is a hollow rectangular skeleton, and the Z-axis cylinder connecting plate 51 is placed inside the rectangular skeleton.
