[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a high-speed conveying roller bed device includes a roller bed conveying base 1, a roller bed conveying pallet 2 and a driving component 3, wherein the roller bed conveying pallet 2 is arranged on the top of the roller bed conveying base 1, and the bottom of the roller bed conveying pallet 2 is in rolling contact with the roller bed conveying base 1, and the driving component 3 is arranged between the roller bed conveying pallet 2 and the roller bed conveying base 1, and is used to provide a driving force for the roller bed conveying pallet 2 to move forward on the roller bed conveying base 1.

[0026] The plate is clamped by the accompanying clamp 21 on the roller bed transport pallet 2 and transported forward on the roller bed transport base 1.

[0027] The roller bed transport base 1 includes a first rail 11, a second rail 12 and load-bearing wheels 13. The first rail 11 and the second rail 12 are arranged in parallel at the axial ends of the top of the roller bed transport base 1. Several of the load-bearing wheels 13 are respectively arranged on the inner sides of the first rail 11 and the second rail 12. The distance between the first rail 11 and the second rail 12 is greater than the width of the roller bed transport pallet 2. Several of the load-bearing wheels 13 are rotatably connected to the first rail 11 and the second rail 12 respectively. The distance between the load-bearing wheels 13 on the first rail 11 and the load-bearing wheels 13 on the second rail 12 is less than the width of the roller bed transport pallet 2. Several of the load-bearing wheels 13 are in rolling contact with the bottom of the roller bed transport pallet 2.

[0028] The length of the side of the roller bed transport pallet 2 parallel to the first track 11 on the roller bed transport base 1 is the length, and the length of the side perpendicular to the first track 11 is the width.

[0029] The width of the roller bed transport pallet 2 is greater than the distance between the load-bearing wheels 13 on the first rail 11 and the load-bearing wheels 13 on the second rail 12, so that the roller bed transport pallet 2 can be placed on the load-bearing wheels 13 on both sides; the width of the roller bed transport pallet 2 is less than the distance between the first rail 11 and the second rail 12, so that the roller bed transport pallet 2 does not contact the first rail 11 and the second rail 12, and during the transportation process, the roller bed transport pallet 2 does not generate friction with the first rail 11 and the second rail 12.

[0030] The driving component 3 includes a linear motor 31 and a magnet 32. The linear motor 31 is axially arranged on the top of the roller bed transport base 1, and the magnet 32 ​​is arranged on the bottom of the roller bed transport pallet 2. The linear motor 31 and the magnet 32 ​​cooperate with each other to provide forward driving force.

[0031] This principle is the same as the principle of the advancement of a maglev train. The linear motor 31 is distributed axially on the roller bed transport base 1. The interaction between the linear motor 31 and the magnet 32 ​​generates a forward thrust, thereby providing a forward driving force for the roller bed transport pallet 2, so that the roller bed transport pallet 2 can continue to move forward on the roller bed transport base 1.

[0032] In order to ensure the balance of the roller bed transport pallet 2 running on the roller bed transport base 1, preferably, the linear motor 31 is arranged at the middle position of the roller bed transport base 1, and the magnet 32 ​​is arranged at the middle position of the bottom of the roller bed transport pallet 2.

[0033] Specifically, when the roller bed transport pallet 2 is working, the magnet 32 ​​at the bottom of the roller bed transport pallet 2 and the linear motor 31 at the top of the roller bed transport base 1 generate a certain repulsive force, so that the distance between the magnet 32 ​​and the linear motor 31 is 6 mm, and it is in a suspended state. The suspended roller bed transport pallet 2 just rolls with the load-bearing wheels 13 on the first track 11 and the second track 12, and the side of the roller bed transport pallet 2 in the length direction is spaced 1 to 2 mm from the guide wheel 14. Therefore, the roller bed transport pallet 2 can achieve high-speed transportation without generating friction with the bottom and sides of the roller bed transport base 1, thereby avoiding noise.

[0034] The roller bed transport base 1 further includes guide wheels 14 , and a plurality of the guide wheels 14 are relatively arranged at the top of the first track 11 and the second track 12 , and the plurality of the guide wheels 14 are rotatably connected to the first track 11 and the second track 12 , respectively.

[0035] Since the guide wheels 14 are installed on the top of the first rail 11 and the second rail 12, the roller bed transport pallet 2 does not contact the guide wheels 14. However, when the linear motor 31 interacts with the magnet 32, the roller bed transport pallet 2 may deviate during the forward movement. After the deviation occurs, the guide wheels 14 on both sides have a limiting effect on the roller bed transport pallet 2. Since the guide wheels 14 are rollingly installed, the roller bed transport pallet 2 is in rolling contact with the guide wheels 14, thereby generating less friction on the side of the roller bed transport pallet 2.

[0036] The roller bed device includes a rough guide component 4, and the rough guide component includes a guide groove 41 (such as Figure 2 As shown) and guide protrusion 42 (as shown Figure 3 As shown), the guide groove 41 is arranged on the top of the roller bed transport base 1, and the guide protrusion 42 is arranged on the bottom of the roller bed transport pallet 2, and the guide groove 41 and the guide protrusion 42 cooperate with each other.

[0037] When the plate to be welded on the roller bed transport pallet 2 moves to the position where welding is required, the rough guide component 4 first preliminarily determines and fixes the position of the roller bed transport pallet 2. Specifically, when the roller bed transport pallet 2 is transported to the position to be welded, the guide protrusion 42 arranged at the bottom of the roller bed transport pallet 2 is embedded in the guide groove 41 arranged at the top of the roller bed transport base 1 to prevent the roller bed transport pallet 2 from shifting in position due to the repulsive force during the forward movement, and failing to directly weld the position to be welded, resulting in welding deviation.

[0038] However, the rough guide component 4 can only provide preliminary guidance for the welding position. Since the welding position requires to be more precise and the plate to be welded on the roller bed transport tray 2 needs to be kept fixed and not shaken, the welding position needs to be further accurately and fixed. Therefore, the positioning component 5 is required for positioning.

[0039] like Figure 4 As shown, the rolling bed device includes a positioning component 5, and the positioning component 5 includes a valve island 51, a telescopic positioning cylinder 52 and a positioning groove 53. The valve island 51 is arranged on the top of the rolling bed transport pallet 2, and the telescopic positioning cylinder 52 is controlled to work by a signal. The two telescopic positioning cylinders 52 are respectively axially arranged on both sides of the top of the rolling bed transport base 1, and the two positioning grooves 53 are respectively axially arranged on both sides of the top of the rolling bed transport pallet 2. The telescopic positioning cylinder 52 and the positioning groove 53 cooperate with each other to realize the precise positioning of the welding position of the plate.

[0040] When the welding position is reached, the valve island 51 controls the pin of the telescopic positioning cylinder 52 to extend, and the extended pin just fits into the positioning groove 53. Since the telescopic positioning cylinder 52 is installed on the roller bed transport base 1 and is stationary, when the pin of the telescopic positioning cylinder 52 fits into the positioning groove 53, the roller bed transport pallet 2 is fixed. In order to prevent the roller bed transport pallet 2 from shaking, two sets of telescopic positioning cylinders 52 and positioning grooves 53 are required to be set, which are respectively installed on both sides of the roller bed transport pallet 2.

[0041] At this time, the roller bed transport pallet 2 is not only fixed in position, but also does not shake, which is more conducive to welding. When welding is completed, the valve island 51 controls the pin of the retracting positioning cylinder 52 to retract, and the pin of the retracting positioning cylinder 52 disengages from the positioning groove 53. Under the driving force of the linear motor 31 and the magnet 32, the guide protrusion 42 slides out of the guide groove 41, so that the roller bed transport pallet 2 drives the panel to continue to move forward and enter the next process.

[0042] The roller bed transport pallet 2 includes a traveling clamp 21 , which is disposed on the top of the roller bed transport pallet 2 and is used to grab panels of different sizes.

[0043] The portable clamp 21 can grab panels of different sizes and shapes, and does not need to be replaced according to the size and shape of the panel, which not only improves work efficiency but also saves costs.

[0044] The rolling bed device includes an energy plate 6 , which is arranged on one side of the top of the rolling bed transport base 1 , and the energy plate 6 is electrically connected to the telescopic positioning cylinder 52 .

[0045] The energy board 6 provides electric energy for the operation of the telescopic positioning cylinder 52, so that the operation can be carried out smoothly.

[0046] The roller bed transport pallet 2 is made of an octagonal tube.

[0047] Since the roller bed transport pallet 2 not only needs to bear the weight of the plate, but also needs to move back and forth, the work intensity is relatively high, so it is made of octagonal tubes, which are more solid and durable.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
