Description

Technical Field

[0001] This application relates to the field of tire technology, and more particularly to a pallet positioning device. Background Technology

[0002] In traditional tire tread production, vulcanized electronic tags serve as the unique identifier for tires throughout their circulation process. However, with the continuous advancement of intelligent manufacturing and the increasing automation in the tire industry, RFID (Radio Frequency Identification) electronic tags for tires are poised for widespread application. Before embedding RFID electronic tags into tires, pre-processing is required: the RFID electronic tag is placed inside two layers of specially formulated rubber sheets, pressed and wrapped, then the protective film attached to the rubber sheets is peeled off, followed by cutting, gripping, and label application.

[0003] With the increasing variety of RFID electronic tag packaging styles, pallet-type RFID electronic tag packaging has begun to be introduced by some manufacturers. The original tag positioning and feeding method is no longer compatible with the pallet-type feeding, positioning, and clamping function. Summary of the Invention

When the second pressure plate descends to the third set position, the second pressure plate presses the tray firmly into the receiving cavity.

[0009] In one specific implementation scheme, the first lifting mechanism and the second lifting mechanism may be a drive cylinder, a drive hydraulic cylinder, or a linear motor.

[0010] In one specific implementation, the pushing mechanism includes a pushing block and a telescopic mechanism connected to the pushing block.

[0020] To facilitate understanding of the pallet positioning device provided in this application embodiment, its application scenario is first described. The pallet positioning device provided in this application embodiment is applied in the automated production process of electronic tag production or use. When electronic tags are used or packaged, they need to be carried by a carrier. Currently, the electronic tags are carried by pallets. However, when using pallets to carry electronic tags, there is no suitable device for positioning and clamping the pallet. Therefore, this application embodiment provides a pallet positioning device for positioning the pallet, so as to facilitate its application in the automated production process. The following is a detailed description of the device with reference to the specific drawings and embodiments.

[0021] refer to Figures 1 to 3 As shown, Figure 1 This paper shows a schematic diagram of the structure of the pallet positioning device provided in an embodiment of this application. Figure 2 A side view of the pallet positioning device provided in an embodiment of this application is shown. Figure 3 This diagram illustrates the pallet positioning device provided in an embodiment of this application from another angle. The pallet 10 positioning device provided in this embodiment mainly includes a reference plate 100 and a mechanism disposed on the reference plate 100 for positioning and clamping the pallet 10. Specifically, the reference plate 100 is provided with a receiving cavity 110 for accommodating the pallet 10. In this configuration, the receiving cavity 110 is larger than the outer edge of the pallet 10 to facilitate placement of the pallet 10 into the receiving cavity 110. Furthermore, since the size of the pallet 10 is smaller than the size of the receiving cavity 110, in this embodiment, the pallet 10 is positioned and clamped by the positioning and clamping mechanism to stably fix it within the receiving cavity 110 of the reference plate 100.

[0022] It should be understood that the existing tray 10 for carrying electronic tags is a rectangular tray 10. Therefore, when setting the receiving cavity 110, the receiving cavity 110 is also a rectangular receiving cavity 110 to ensure the compatibility of the two.

[0023] To facilitate the positioning of the tray 10, in this embodiment, the tray 10 is positioned using the two inner edges of the receiving cavity 110. Since the tray 10 used is a rectangular tray 10, in this embodiment, two adjacent inner edges of the receiving cavity 110 are used as positioning edges. For ease of description, the two inner edges are named the first inner edge 111 and the second inner edge 112, respectively. During positioning, the outer edge of the tray 10 is abutted against the first inner edge 111 and the second inner edge 112 to ensure consistent position when fixed. For ease of description, a first direction, a second direction, and a third direction are defined, wherein the first direction, the second direction, and the third direction are mutually perpendicular, and the first direction is perpendicular to the first inner edge 111, the second direction is perpendicular to the second inner edge 112, and the first direction and the second direction are parallel to the bearing surface of the receiving cavity 110 when it supports the tray 10.

[0024] The positioning and clamping mechanism in the positioning device for the tray 10 provided in this application mainly includes a pushing mechanism 600 and two clamping mechanisms. For ease of description, the two clamping mechanisms are respectively named the first clamping mechanism 400 and the second clamping mechanism 500. The pushing mechanism 600 is used to push the tray 10 against the first inner edge 111 of the receiving cavity 110. Exemplarily, when the tray 10 is placed in the receiving cavity 110, the pushing mechanism 600 pushes the tray 10 toward the first inner edge 111, and when the tray 10 abuts against the first inner edge 111, it positions the tray 10 in a first direction.

[0025] The first clamping mechanism 400 serves two purposes: firstly, it cooperates with the second clamping mechanism 500 to clamp and position the pallet 10; secondly, it pushes the pallet 10 against the second inner edge 112 to position the pallet 10 in the second direction. Specifically, in use, the first clamping mechanism 400 first pushes the pallet 10 to move, and when it abuts against the second inner edge 112 of the receiving cavity 110, it positions the pallet 10 in the second direction. Then, the first clamping mechanism 400 clamps the pallet 10, thereby clamping the pallet 10 in the direction perpendicular to the bearing surface (the third direction).

[0026] When clamping the tray 10, the second clamping mechanism 500 and the first clamping mechanism 400 can be used simultaneously to clamp and fix the tray 10, ensuring the stability of the tray 10 during clamping. Specifically, the second clamping mechanism 500 is disposed on the second inner edge 112 of the receiving cavity 110, that is, the first clamping mechanism 400 and the second clamping mechanism 500 are arranged on both sides of the receiving cavity 110 along the second direction. When the tray 10 abuts against the first inner edge 111 and the second inner edge 112 respectively, the first clamping mechanism 400 and the second clamping mechanism 500 can clamp the tray 10, thereby limiting the tray 10 in the third direction and ensuring the stability of the tray 10 during positioning.

[0027] It should be understood that when positioning and clamping the pallet 10, the pallet 10 needs to be pressed against the first inner edge 111 and the second inner edge 112 by the cooperation of the first clamping mechanism 400 and the pushing mechanism 600, so as to position the pallet 10. Then, the pallet 10 is pressed and fixed in the receiving cavity 110 of the reference plate 100 by the cooperation of the first clamping mechanism 400 and the second clamping mechanism 500.

[0028] As can be seen from the above description, in the technical solution disclosed in this application, by using the first pressing mechanism 400 and the pushing mechanism 600 to cooperate, the tray 10 can be positioned on the first inner edge 111 and the second inner edge 112 of the receiving cavity 110 of the reference tray 10, and the tray 10 is pressed into the reference plate 100 by the cooperation of the first pressing mechanism 400 and the second pressing mechanism 500, thereby fixing the tray 10 in the set position on the reference plate 100, which facilitates the positioning and fixing of the tray 10.

[0029] In one optional embodiment, to ensure accurate positioning of the pallet 10, a first positioning block 200 is provided on the first inner edge 111. There are at least two first positioning blocks 200, and these at least two first positioning blocks 200 are spaced apart along the direction of the first inner edge 111. The pallet 10 abutting against the first inner edge 111 means that the pallet 10 abuts against at least two first positioning blocks 200 on the first inner edge 111, thereby positioning the pallet 10 in a first direction using the two first positioning blocks 200. In one example, there are two first positioning blocks 200, and the pallet 10 is positioned in the first direction using the two first positioning blocks 200.

[0030] In an alternative embodiment, a second positioning block 300 may also be provided along the second inner edge 112. The number of second positioning blocks 300 is at least one, and when there are two or more second positioning blocks 300, the two or more second positioning blocks 300 are spaced apart along the length direction of the second inner edge 112. That is, when there are two or more second positioning blocks 300, the two or more second positioning blocks 300 are spaced apart along the first direction, so that positioning in the second direction is achieved by different second positioning blocks 300 abutting against the tray 10.

[0031] In an optional embodiment, the pushing mechanism 600 provided in this application may also employ an elastic mechanism as the pushing mechanism 600. For example, the elastic mechanism may include a swing block 610 rotatably connected to the reference plate 100, which can be driven by a torsion spring or a compression spring. When the tray 10 is not placed in the receiving cavity 110, the swing block 610 can be inserted into the receiving cavity 110 under the drive of the torsion spring or compression spring. When the tray 10 is placed in the receiving cavity 110, the tray 10 pushes the swing block 610 to swing away from the receiving cavity 110, while the torsion spring or compression spring undergoes elastic deformation. Under the elastic force of the torsion spring or compression spring, the swing block 610 can push the tray 10 against the first inner edge 111.

[0032] Of course, in addition to the pushing mechanism 600 in the example above, the pushing mechanism provided in this application embodiment can also be an active pushing mechanism. For example, the pushing mechanism 600 includes a pushing block and a telescopic mechanism that pushes the pushing block to move. The telescopic mechanism is fixed to the base plate 100 and connected to the pushing block. The telescopic direction of the telescopic mechanism is perpendicular to the length direction of the first inner edge 111, so that the pushing block can achieve reciprocating motion along the first direction when the telescopic mechanism extends and retracts. When the pushing block moves to the fourth set position, the pushing block pushes the tray 10 against the first inner edge 111. When the tray 10 is placed into the receiving cavity 110, the telescopic mechanism retracts, causing the pushing block to avoid the tray 10, so as to ensure that the tray 10 can be easily placed into the receiving cavity 110. When the tray 10 is placed into the receiving cavity 110, and the telescopic mechanism drives the pushing block to move to the fourth set position, it can press the tray 10 against the first inner edge 111. When the first positioning block 200 is provided on the first inner edge 111, the tray 10 presses against the first positioning block 200.

[0033] In a specific example, the telescopic mechanism is a drive cylinder, a drive hydraulic cylinder, or a linear motor. Alternatively, other linear drive mechanisms can be used as the telescopic mechanism.

[0034] In one feasible solution, the number of pushing mechanisms 600 provided in this application embodiment is two, and the two are arranged at intervals along the length direction of the first inner edge 111, so as to ensure that the pallet 10 can be translated when pushing the pallet 10, avoiding the situation of offset when pushing the pallet 10, and ensuring the accuracy of positioning.

[0035] In a specific implementation scheme, the first pressing mechanism 400 provided in this application embodiment can push the tray 10 and press the tray 10. Different mechanisms can be used to implement this. In a specific example, the first pressing mechanism 400 includes a push plate 420, a first lifting mechanism 430 disposed on the push plate 420, and a first pressure plate 410 connected to the first lifting mechanism 430. The push plate 420 is slidably connected to the reference plate 100, and the sliding direction of the push plate 420 is perpendicular to the length direction of the second inner edge 112, that is, the sliding direction of the push plate 420 is parallel to the second direction. When the push plate 420 slides back and forth in the second direction, it can move away from or closer to the tray 10. When the push plate 420 slides to a first set position, the push plate 420 can push the tray 10 against the second inner edge 112, thereby positioning the tray 10 in the second direction. When the push plate 420 slides to the non-working position, the push plate 420 is located outside the receiving cavity 110 of the reference plate 100 to avoid the first pressing mechanism 400 affecting the placement of the tray 10.

[0036] The lifting direction of the first lifting mechanism 430 is along the thickness direction of the reference plate 100, that is, along the third direction, thereby driving the first pressure plate 410 to lift and lower in the third direction. When the first pressure plate 410 descends to the second set position, the first pressure plate 410 can press the tray 10 into the receiving cavity 110, thereby limiting the tray 10 in the third direction.

[0037] In one specific implementation, the push plate 420 can be mounted on the reference plate 100 via a slide rail and driven to reciprocate in a second direction by a drive mechanism 440. For example, the drive mechanism 440 can be a common linear drive mechanism 440 such as a drive cylinder, a drive hydraulic cylinder, or a linear motor.

[0038] When specifically setting the push plate 420, a notch communicating with the receiving cavity 110 can be opened on the base plate 100. When the push plate 420 moves to the first set position, the push plate 420 is inserted into the receiving cavity 110 and abuts against the tray 10. When the push plate 420 moves to the non-working position, the push plate 420 is hidden in the notch.

[0039] In one specific implementation, the first lifting mechanism 430 can be a drive cylinder, a drive hydraulic cylinder, or a linear motor. Of course, in addition to the drive mechanism exemplified above, other lifting mechanisms can also be used to drive the first pressure plate 410.

[0040] In one specific implementation scheme, the second pressing mechanism 500 provided in this application is used to cooperate with the first pressing mechanism 400 to position the tray 10 in a third-dimensional direction. Specifically, the second pressing mechanism 500 includes a second lifting mechanism 520 and a second pressure plate 510 connected to the second lifting mechanism 520. The second lifting mechanism 520 is disposed on the reference plate 100 and is located on both sides of the receiving cavity 110, opposite to the first lifting mechanism 430. The lifting direction of the second lifting mechanism 520 is along the thickness direction of the reference plate 100, i.e., along the third-dimensional direction. When the second pressure plate 510 descends to a third predetermined position, it presses the tray 10 firmly into the receiving cavity 110. The working principle of the second pressure plate 510 and the second lifting mechanism 520 is the same as that of the first pressure plate 410 and the first lifting mechanism 430, and will not be described in detail here.

[0041] In one specific implementation, the second lifting mechanism 520 can be a drive cylinder, a drive hydraulic cylinder, or a linear motor. Of course, in addition to the drive mechanism exemplified above, other lifting mechanisms can also be used to drive the second pressure plate 510.

[0042] In one feasible embodiment, the positioning device for the pallet 10 provided in this application further includes a support base 700, with the reference plate 100 slidably connected to the support base 700. The support base 700 can support the reference plate 100, and when the reference plate 100 slides on the support base 700, it can move the reference plate 100 to different positions, thereby meeting the need for moving the pallet 10.

[0043] As can be seen from the above description, the positioning device for the tray 10 provided in this application embodiment can limit the tray 10 within a reasonable tolerance range through the cooperation of the first pressing mechanism 400, the second pressing mechanism 500, and the pushing mechanism 600, providing a better benchmark for the subsequent label retrieval and positioning. Furthermore, the number and pressing sequence of the pressure plates of the first pressing mechanism 400 and the second pressing mechanism 500 in contact with the tray 10 can effectively eliminate the bending deformation caused by the pressure on the tray 10 during the positioning process. In a specific configuration, in this application embodiment, it is preferable that the first pressure plate 410 has two positions in contact with the tray 10, and the second pressure plate 510 has one position in contact with the tray 10. The first pressure plate 410 has two positions pressing on the center line of the tray 10 and the center of the two rows of grooves on the tray 10, respectively. When the tray 10 has other numbers of grooves, adjustments can be made as needed, with the same principle.

[0044] The positioning device for pallet 10 provided in this application embodiment solves the problem of position tolerance control for double or multi-row electronic tags in pallet 10 packaging, providing a positional reference for subsequent automated processes. It ensures the flatness of the pallet 10 after clamping, providing a height reference for subsequent automated processes.
