Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a plate flip buffer conveyor. Background Art

[0002] In the processing and production of circuit boards and other panels, it is often necessary to transport the circuit boards to different workstations for processing. Since the processing time required for different workstations is different, or the circuit board processed by one workstation needs to wait for a preset time before it can be transported to the next workstation for processing, it is necessary to transport the panels through a flip-plate buffer conveyor. The applicant applied for a Chinese patent document with application number 202123220020.4 on December 17, 2021, which discloses a panel flip-plate buffer conveying device, including a machine, a rotating buffer device, a feed conveying mechanism and a discharge conveying mechanism. The rotating buffer device includes an upper transmission sprocket group, a lower transmission sprocket group, a transmission chain connected to the upper transmission sprocket group and the lower transmission sprocket group, a rotating drive mechanism for driving the upper transmission sprocket group or / and the lower transmission sprocket group to rotate, and a plurality of support components respectively installed on the outer side wall of each chain link of the transmission chain, and the upper transmission sprocket group is located above the lower transmission sprocket group. Although the patent document realizes the automatic feeding, buffering, conveying and discharging of plates, the slider and the guide rail on the support assembly are sliding friction, which has large friction resistance and wear. Once a heavy plate is conveyed, the gravity of the heavy plate acts on the support assembly instantly, so the support assembly is prone to falling, which makes the conveying stability of the support assembly for the plate worse. Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a plate flip buffer conveyor.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The conveyor belt conveyor of claim 1, wherein the conveyor belt conveyor is provided with a plurality of guide rails, each guide rail having a plurality of guide rails disposed on the conveyor belt conveyor and a plurality of guide rails connected to the conveyor belt conveyor.

[0006] Furthermore, each set of anti-falling support mechanisms has two anti-falling support modules, and the two anti-falling support modules are respectively located at two ends of the support assembly.

[0007] Furthermore, the anti-fall support module includes a support driver installed on the machine and a support plate installed on the driving end of the support driver. The support plate is provided with a support plug block, which is used to be inserted between two adjacent support components and provide anti-fall support to the bottom surface of the end of the bottom support component in the guide rail.

[0008] Furthermore, the support assembly includes a connecting rod connected to the chain links of the transmission chain, multiple support rods connected to the connecting rod, and a limiting protrusion arranged on the connecting rod, and a fixed plate gap is provided between the limiting protrusion and the multiple support rods; the rolling member is rotatably connected to the end of the connecting rod.

[0009] Furthermore, the feed conveying mechanism and / or the discharge conveying mechanism includes a conveying driver, a transmission assembly and multiple conveying assemblies. The conveying driver is installed on the machine. The conveying driver drives all the conveying assemblies to rotate synchronously via the transmission assembly. Multiple conveying assemblies are arranged and mounted on the machine. Multiple conveying assemblies and multiple support rods are spaced apart. There is a rotating space between two adjacent conveying assemblies for the support rods to rotate.

[0010] Furthermore, the number of upper transmission sprocket groups and the number of lower transmission sprocket groups are both two, the two upper transmission sprocket groups are arranged in parallel, the two lower transmission sprocket groups are arranged in parallel, and the rotation drive mechanism is drivingly connected to one of the lower transmission sprocket groups.

[0011] Further, the distance between the two upper transmission sprocket sets is less than or equal to the distance between the two lower transmission sprocket sets.

[0012] Furthermore, there are two transmission chains, which are arranged in parallel, and both ends of the support assembly are respectively mounted on corresponding chain links of the two transmission chains.

[0013] Furthermore, the machine is provided with a feed port and a discharge port. The feed port is provided corresponding to the feed end of the feed conveying mechanism, and the discharge port is provided corresponding to the discharge end of the discharge conveying mechanism.

[0014] The beneficial effects of the utility model are as follows: in actual application, the rotating drive mechanism drives the upper transmission sprocket group or / and the lower transmission sprocket group to rotate synchronously, the rotating upper transmission sprocket group or / and the lower transmission sprocket group drives the transmission chain to rotate, and the rotating transmission chain drives all the support components to rotate synchronously. At the same time, the feed conveying mechanism orderly conveys the plate to between two adjacent support components of the rotating buffer device. As the transmission chain and all the support components rotate synchronously, the multiple support components on the transmission chain carry, convey and cache the plate conveyed by the feed conveying mechanism. When the plate follows the rotating buffer device to rotate to the discharging conveying mechanism, the discharging conveying mechanism carries the plate and outputs the plate. In the process of the transmission chain driving the multiple support components to move, the rolling elements on the support components in the longitudinal conveying section of the transmission chain roll on the inner wall of the channel of the corresponding guide rail, which not only makes the movement of the support component stable and smooth, but also reduces the friction resistance and wear between the support component and the guide rail. In addition, when the feed conveying mechanism conveys the plate to the support assembly at the bottom end of the guide rail, a group of anti-fall support mechanisms provide anti-fall support for the bottom surface of the support assembly to prevent the support assembly from falling due to the gravity of the plate in an instant, thereby ensuring that the rolling elements on the support assembly can accurately enter the guide rail and enable the support assembly to stably convey the plate. When the rolling elements on the support assembly enter the guide rail and stably convey the plate, the group of anti-fall support mechanisms release the anti-fall support for the support assembly to prevent the anti-fall support mechanisms from interfering with the rotation of the transmission chain. Similarly, when the support assembly conveys the plate to the discharging conveying mechanism, another group of anti-fall support mechanisms provide anti-fall support for the bottom surface of the support assembly to prevent the plate on the support assembly from falling instantly onto the discharging conveying mechanism, thereby preventing the plate from having a hard impact and collision with the discharging conveying mechanism, thereby protecting the plate and the discharging conveying mechanism and improving the stability of the discharging conveying mechanism in conveying the plate. The utility model realizes the automatic feeding, buffer conveying and discharging of plates. The supporting components have low friction resistance, low wear and smooth movement. The feeding and discharging of plates can be supported to prevent them from falling, thereby improving the stability of conveying the plates. The utility model is particularly suitable for conveying heavy plates. BRIEF DESCRIPTION OF THE DRAWINGS
