[0002] When performing automated or semi-automated processing on some boards, such as using an edge banding machine to perform edge banding operations on the boards, the boards need to be conveyed first so that the boards move forward in a specified direction. During the conveying process, it is necessary to ensure that the boards cannot shake in the up and down directions to ensure the smooth movement of the boards. Therefore, a pressing device can be installed above the boards. However, the existing pressing device cannot guarantee the amount of force applied to the boards when pressing the boards, and indentations will appear on the boards.

[0030] Below, combined with the attached Figure 1 To the attached Figure 8 As well as specific implementation methods, the present invention is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] like Figures 1-8As shown, a plate auxiliary conveying and pressing device includes a workbench, a plate 2, a conveying device 3 for frictionally engaging with the side of the plate 2 to achieve conveyance, and an auxiliary device 4 for frictionally engaging with the top of the plate 2;

[0032] Specifically, such as Figure 1 and Figure 2 The support plate 2 is fixed to the workbench 11 and the support plate 2 is fixed to the workbench 11. Figure 2As shown, the conveying device 3 of the present device includes a conveying drive, a vertical shaft 31 and a bonding wheel 32. The vertical shaft 31 is rotatably arranged on the support plate 1 through a bearing. The vertical shaft 31 is arranged on the side of the fixed boss 112 away from the straight edge of the support plate 1. The vertical shaft 31 is higher than the fixed boss. The upper end of the vertical shaft 31 is higher than the support plate 1 and the bonding wheel 32 is fixed. The lower end of the vertical shaft 31 is lower than the support plate 1 and is equipped with a first sprocket 311. The first sprocket 311 is rotatably connected and matched with the conveying drive. The conveying drive is generally a motor. The motor drives the first sprocket 311 to rotate through a chain, which is a common knowledge in the art. The vertical shaft 31 is connected to the conveying drive and rotates above the workbench through the conveying drive. The laminating wheel 32 rotates following the vertical shaft 31. When the side of the plate 2 is in close contact with the laminating wheel 32, the side of the plate 2 will be subjected to friction, thereby pushing the plate 2 to move forward. In order to ensure the smooth progress of the plate 2 and prevent the plate 2 from floating up and down or deviating from the direction, the device is also provided with an auxiliary device 4, which includes a lifting device 41, an omnidirectional wheel 42 and a driving device 43 for driving the omnidirectional wheel 42 to rotate. The lifting device 41 is provided with a Above the support area 11, the omnidirectional wheel 42 is set on the lifting device 41. The omnidirectional wheel 42 includes a hub 421 and a plurality of driven wheels 422 evenly arranged along the circumference of the hub 421. The radial direction of the driven wheel 422 is perpendicular to the tangent direction of the outer circumference of the hub 421. The driven wheel 422 rotates along the forward direction of the plate 2. When the lifting device 41 descends, the omnidirectional wheel 42 will fit with the plate 2, and the driving device 43 will drive the omnidirectional wheel 42 to rotate toward the straight edge direction of the support plate 1. As the omnidirectional wheel 42 rotates, the omnidirectional wheel 42 will exert force on the plate 2 toward the support plate 1. The force on the straight edge side is applied, thereby preventing the plate 2 from deflecting. At the same time, when the plate 2 moves forward, in the forward direction of the plate 2, the friction between the omnidirectional wheels 42 and the omnidirectional wheels 42 will become the force driving the driven wheel 422 to roll. In the process of the plate 2 moving forward, the overall rotation of the omnidirectional wheels 42 can provide the necessary radial friction to the plate 2 to ensure stable transportation of the plate 2. At the same time, the driven wheel 422 on the omnidirectional wheels 42 can rotate along with the forward movement of the plate 2, effectively eliminating the axial friction, thereby greatly reducing the wear on the surface of the plate 2, removing the indentation, and making the plate surface more beautiful.

[0033] As a further optimization, the wheel hub 421 rotates toward the fitting wheel 32, and the friction and reaction force formed between the omnidirectional wheel 42 and the plate 2 will be toward the fitting wheel 32. The plate 2 will be closer to the fitting wheel 32, so that the fitting wheel 32 will generate greater friction on the plate 2, thereby providing greater forward power for the plate 2.

[0034] As a specific description of the omnidirectional wheel 42, the hub 421 includes an intermediate wheel 423 and two circular side plates 424 provided on both sides of the intermediate wheel 423, the driven wheels 422 are rotatably provided on the circular side plates 424, and the driven wheels 422 on the two circular side plates 424 are staggered. Specifically, Figure 7 and Figure 8 As shown, the driven wheel 422 includes a central axis 4223 and a rubber rotating wheel 4224, and the circular side plate 424 includes an intermediate plate 425 and a clamping plate 426. The intermediate plate 425 and the clamping plate 426 are circular flat plates of the same shape, and the intermediate plate 425 and the clamping plate 426 are respectively arrayed with a first trapezoidal groove 427 and a second trapezoidal groove 428 for rotating the driven wheel 422. A positioning notch 429 for inserting the central axis 4223 is provided on the side wall of the first trapezoidal groove 427. The first trapezoidal groove 427 and the second trapezoidal groove 428 are staggered on the circular side plates 424 on both sides of the intermediate wheel 423. In this way, when the omnidirectional wheel 42 rotates, it can be ensured that the rubber rotating wheel is in contact with the plate 2 at any angle.

[0035] As a specific description of the lifting device 41, Figure 3 As shown, the lifting device 41 includes a frame 411, a movable plate 412 and a telescopic device 413.

The rear end of the cross bar 4111 is fixedly connected to the upper end of the support bar 4113, and the lower end of the support bar 4113 is fixed to the support plate 1. The upper end of the vertical shaft 4112 is fixed to the middle of the cross bar 4111, and the lower end of the vertical shaft 4112 is fixed to the support plate 1. The front end of the cross bar 4111 is fixedly connected to a fixed plate 4114, which is a vertical plate. The movable plate 412 is relatively slidably arranged with the fixed plate 4114. The sliding arrangement structure has multiple In this embodiment, two fixed blocks 4115 are fixed on the fixed plate 4114, and two parallel sliding grooves are provided on the two fixed blocks 4115. Two guide rails 4121 are fixed on the movable plate 412, and the two guide rails 4121 slide in cooperation with the two sliding grooves to realize the interactive setting of the movable plate 412 and the fixed plate 4114. One end of the telescopic device 413 is connected to the fixed plate 4114, and the other end of the telescopic device 413 is connected to the movable plate 412. The movable plate 412 is lifted and lowered by the extension and retraction of the telescopic device 413.

[0036] As a specific description of the telescopic device 413, the telescopic device 413 has various types, such as an electric telescopic rod, a hydraulic bar light, and in this embodiment, Figure 5As shown, the telescopic device 413 is a telescopic cylinder, the fixed plate 4114 is a vertical long plate, and an inverted L-shaped suspension plate 4116 is fixed to the upper end of the fixed plate 4114. The cylinder barrel of the telescopic cylinder is fixed on the movable plate 412, and the piston rod of the telescopic cylinder is fixedly connected to the suspension plate 4116 through a connecting rod. The height of the movable plate 412 is controlled by the extension and contraction of the telescopic cylinder, thereby controlling the height of the omnidirectional wheel 42. The electric telescopic cylinder is not only simple to install, but also more precisely positioned, which can accurately control the pressure of the omnidirectional wheel 42 on the plate 2 to avoid large indentations.

[0037] Furthermore, the omnidirectional wheel 42 is rotatably mounted on the lower end of the movable plate 412, and the driving device 43 includes a driving motor 431 and a transmission mechanism 432. The driving motor 431 is fixed to the movable plate 412 and is rotatably connected to the omnidirectional wheel 42 via the transmission mechanism 432. Figure 6 As shown, the movable plate 412 is a vertical long plate, and an electric cylinder fixing plate 4122 for fixing the telescopic cylinder is provided in the middle of the movable plate 412, and a motor fixing plate 4123 for installing the drive motor 431 is protruded on one side of the middle of the movable plate 412. The omnidirectional wheel 42 rotates at the lower end of the movable plate 412, and a second sprocket 4322 is installed on the rotating shaft of the drive motor 431. A third sprocket 4323 is installed on the rotating shaft of the omnidirectional wheel 42. The second sprocket 4322 and the third sprocket 4323 are connected by a chain, and a tensioner 4321 is installed on one side of the chain. This design is compact, occupies less space, and ensures the smooth rotation of the omnidirectional wheel 42.

[0038] As an optimization, the conveying device 3 also includes a guide bearing assembly 5, which includes a fixed shaft 51 and a plurality of guide rotating parts rotating on the fixed shaft 51, and the guide rotating parts are slidingly matched with the plate 2.
