[0002] During the production process of PCB boards, due to the different production rhythms in different production stages, in order to make the processing flow smoother, it is very necessary to design a cache mechanism for the PCB boards in the processing flow.

[0003] Existing patent CN209582897U, "A Novel Temporary Storage Mechanism," discloses a buffering mechanism for PCB boards. Most prior art, including this patent, utilizes a conveyor line in this mechanism that uses a drive motor to drive a belt or gears, among other connectors, to rotate a conveyor roller to transport the PCB boards. Because the output end of the drive motor and the conveyor roller utilize a contact-driven mechanism, friction exists, inevitably causing some wear on the belts and gears. Belt tension can also cause problems such as excessive friction or breakage.

[0004] In order to solve the above problems, designing a cache mechanism is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0025] The objectives, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

Therefore, they should not be construed as limitations on the present invention.

Furthermore, in the description of the scheme, with the operator as a reference, the direction closer to the operator is referred to as the proximal end, and the direction away from the operator is referred to as the distal end.

[0027] like Figures 1 to 2 As shown, the utility model discloses a buffer mechanism, including a conveyor line 1, the conveyor line 1 including a drive motor 11, a power roller 12 and a conveyor roller 13 arranged at the conveying end of the drive motor 11. The power roller 12 is perpendicular to the conveyor roller 13 and is arranged in a non-contact manner. The power roller 12 drives the conveyor roller 13 to rotate by magnetic force. Figure 2As shown, both ends of the conveying rod 13 are mounted on the conveying frame 10, and a driven magnetic wheel 131 is provided at one end of the conveying rod 13; the power roller 12 is fixed to the conveying frame 10 via a connecting plate, and a set of active magnetic wheels 121 are provided on the power roller 12. The active wheels 121 correspond one-to-one with the driven magnetic wheels 131, and there is no contact between the two. Designing the conveyor line as a magnetic conveyor line, which drives the conveying rod to rotate by magnetic force, reduces friction between components compared to existing contact conveyor lines, avoids component wear, and extends the practical life of the conveyor line and the cache mechanism; at the same time, it reduces the footprint of the cache mechanism.

[0028] Furthermore, the output end of the drive motor 11 is directly or indirectly connected to the power roller 12, and drives the power roller 12 to rotate synchronously therewith. Direct connection means that the output end of the drive motor 11 is connected to the end of the power roller 12, and after the drive motor 11 is started, the power roller 12 rotates synchronously. Indirect connection means that the output end of the drive motor 11 and the power roller 12 can be connected by a speed reduction mechanism disclosed in the known technology such as a speed reduction belt or gear point, and after the drive motor 11 is started, the power roller 12 is driven to rotate synchronously through the speed reduction mechanism.

[0029] A set of damping sleeves are evenly spaced on each of the conveying rollers 13, which can reduce the contact area between the PCB board and the conveying roller 13, thereby reducing friction. Figure 2 As shown, in the present invention, the damping sleeves on two adjacent conveying rollers 13 are preferably arranged alternately.

[0030] like Figures 1 to 2 As shown, guide rollers 14 are vertically positioned at both the input and output ends of the conveyor roller 13, symmetrically arranged on the conveyor roller 13. The spacing between the two guide rollers 14 is adjustable. Adjusting the distance between the guide rollers 14 accommodates PCBs of varying sizes. The guide rollers 14 also position the PCBs during conveyance, ensuring they do not shift or collide with the conveyor frame 10, thus ensuring a high yield. The number of guide rollers 14 can be adjusted as needed and is not a specific requirement here.

[0031] Further, such as Figure 2As shown, a first sensor 151 and a second sensor 152 are also provided on the conveying rod 13. The first sensor 151 is arranged in the vertical direction to detect whether the PCB board exists on the upper surface of the conveying rod 13. The second sensor 152 is arranged below the conveying rod 13 to detect whether there is storage space on the cache group 31 located below the conveyor line 1. That is, when the first sensor 151 detects that there is the PCB board to be processed on the current conveyor line 1, a signal to start the cache box 3 is sent to the drive component 2, and after the second sensor 152 detects that there is storage space on the current cache group, a storage space signal is sent to the drive component 2 until the PCB board is placed on the storage space.

[0032] A cache mechanism further includes a drive assembly 2 and a cache box 3, and the cache box 3 is driven by the drive assembly 2 to rise and fall relative to the conveyor line 1. Figure 1 and Figure 3 As shown, the buffer box 3 includes at least one buffer group 31 spaced apart along the direction of travel of the conveyor line 1, and the buffer group 31 is disposed between two adjacent conveyor rollers 13. Each buffer group 31 forms a storage space for PCB sheets. The buffer groups are spaced apart between the conveyor rollers of the conveyor line and raised and lowered relative to the conveyor rollers, reducing the volume of the buffer mechanism and improving space utilization. This also facilitates the rapid placement of PCB sheets from the conveyor line into the buffer box, reducing PCB sheet accumulation on the conveyor line and streamlining the processing flow.

[0033] Specific as Figure 3 As shown, the cache box 3 includes a frame 30 and a cache group 31 arranged in the frame 30. Figure 4 As shown, the cache group 31 is composed of a group of support rods 311 arranged at intervals, and a group of the support rods 311 is arranged along the moving direction of the cache box 3. A group of the support rods 311 located on the same horizontal line can be used to carry a piece of the PCB board, and form a storage space for storing the PCB board between the group of the support rods 311 located above and below it. The first side wall of the frame 30 is located on the outside of the conveyor line 1, and the second side wall is located on the inside of the conveyor line 1; all the cache groups 31 are connected to the inside of the frame 30 through a fixing plate 32 to increase the overall connection reliability of the cache box. The cache box and the conveyor line are staggered to greatly reduce the overall floor space, which is suitable for various types of processing plants and units.

[0034] like Figure 1As shown, in the present invention, the drive assembly 2 is preferably designed as a servo module. Since the servo module is a known prior art, its specific structure is not described in detail here. The output end of the servo module is connected to the first side wall or the second side wall via the first connecting plate 211, and drives the cache box 3 to rise and fall. The drive assembly cooperates with the cache box to drive the cache box to rise and fall, and in this process, the PCB plates on the conveyor line are moved into the cache box. The overall operation is simple, the process is smooth and efficient, the retention time of the PCB plates on the conveyor line is shortened, and the transfer efficiency is improved.

[0035] Further, combined Figure 1 and Figure 3 As shown, guide rails 22 are provided on both sides of the servo module. The height of the guide rails 22 is greater than that of the conveyor line 1. The first connecting plate 211 and the second connecting plate 212 are slidably connected to the guide rails 22; the second connecting plate 212 is connected to the first side wall or the second side wall. The guide rails 22 enhance the connection reliability between the buffer box 3 and the drive assembly 2, while also sharing the force applied by the drive assembly 2 during movement, making the raising and lowering of the buffer box 3 smoother.

[0036] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
