DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments 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.

[0022] like Figure 1-4As shown, an automatic patch device for flexible PCB boards includes a patch table 1, which is the main structure of the device and provides an operating platform for patch operations. A storage bin 2 is provided at the bottom of the patch table 1, and a discharge port communicating with the storage bin 2 is provided at the top of the patch table 1. A discharge cylinder 3 is provided at the bottom of the storage bin 2. The storage bin 2 is used to store PCB boards 12. The PCB boards 12 can be pushed upward by the discharge cylinder 3. The top PCB board 12 is flush with the top of the patch table 1, thereby facilitating subsequent feeding operations. An anti-retraction angle steel 4 is symmetrically connected to one side of the top of the patch table 1. When the PCB board 12 is pushed out from the storage bin 2, the PCB board 12 is pushed upward by the discharge cylinder 3. When the anti-recession angle steel 4 is in the state of being moved, the anti-recession angle steel 4 can form a good limit for its PCB board 12. The other side of the top of the patch platform 1 is symmetrically connected to the limited angle steel 5. A pad seat 6 is arranged on the top of the patch platform 1. The pad seat 6 is located on one side of the anti-recession angle steel 4. An electric push rod 7 is connected to the top of the pad seat 6. One end of the electric push rod 7 is connected to an L-shaped end seat 8. The L-shaped end seat 8 is located above the anti-recession angle steel 4. An inner cavity 9 is provided at the bottom of the L-shaped end seat 8. A spring 10 is arranged inside the inner cavity 9. A push block 11 matching the inner cavity 9 is connected to the bottom of the spring 10. The outer side of the push block 11 contacts the inner wall of the inner cavity 9. The shape of the push block 11 is The push block 11 is a right-angled trapezoid, and the inclined surface of the push block 11 is away from one side of the anti-recession angle steel 4. The pad seat 6 provides an installation position for the electric push rod 7, which ensures the stability of the electric push rod 7 during work. At the same time, the electric push rod 7 can be lifted to a certain height, which is convenient for driving the L-shaped end seat 8 to push the PCB board 12 for loading. The spring 10 forms an elastic support for the push block 11 set in the inner cavity 9. The inclined surface of the push block 11 will compress the spring 10 after encountering resistance, so that the push block 11 can be recovered into the inner cavity 9. Since the inclined surface of the push block 11 is away from one side of the anti-recession angle steel 4, when the L-shaped end seat 8 moves to one side for loading operation, it is set The push block 11 at the bottom of the L-shaped end seat 8 can push the PCB board 12 from one side to realize loading. When the PCB board 12 is pushed to the patch point, one side of the PCB board 12 is squeezed by the push block 11, and the other side of the PCB board 12 is squeezed by the limiting angle steel 5, thereby realizing the fixation of the PCB board 12. When the patch is completed, the electric push rod 7 drives the L-shaped end seat 8 to be recovered. During the recovery process, since the anti-retraction angle steel 4 forms a limit for a new group of PCB boards 12, the inclined surface of the push block 11 will be squeezed by the new group of PCB boards 12 at this time, thereby recovering it into the inner cavity 9, ensuring the normal recovery of the L-shaped end seat 8.

[0023] In the present embodiment, specifically, a plurality of groups of PCB boards 12 are placed inside the storage bin 2, and limiting strips 13 matching the PCB boards 12 are symmetrically arranged between the anti-recession angle steel 4 and the limiting angle steel 5. During the movement of the PCB boards 12, the limiting strips 13 can limit the two sides of the PCB boards 12 to avoid displacement during the movement, thereby ensuring that the PCB boards 12 can accurately enter the patch area and improving the accuracy of the patch.

[0024] In the present embodiment, specifically, a support frame 14 is connected to the top edge of the patch table 1, a patch cylinder 15 is arranged on the top of the anti-recession angle steel 4, a patch head 16 is connected to the bottom end of the patch cylinder 15, and the patch cylinder 15 drives the patch head 16 to rise and fall so as to realize the patch operation on the PCB board 12.

[0025] In the present embodiment, specifically, a push-pull groove 17 is opened on one side of the storage bin 2, and a sealing plate 18 is slidably connected inside the push-pull groove 17. A limit frame 19 is arranged at the bottom of the patch table 1, and the inner wall of the limit frame 19 is in contact with the outer side of the sealing plate 18. The storage bin 2 can be sealed by the provided sealing plate 18. When the device is not in use, the sealing of the storage bin 2 by the sealing plate 18 can effectively prevent external dust and debris from falling into the storage bin 2.

[0026] The working principle of the utility model is as follows: when the device is in use, the PCB board 12 is stacked into the storage bin 2, the PCB board 12 is pushed to be flush with the top of the patch table 1 by the discharge cylinder 3, and then the electric push rod 7 is started, and the L-shaped end seat 8 is driven by the electric push rod 7 to move to one side to push the PCB board 12 to the limit angle steel 5, and then the patch head 16 is driven by the patch cylinder 15 to lift and patch the PCB board 12. After the patch is completed, the electric push rod 7 drives the L-shaped end seat 8 to be recovered. During the recovery process, the inclined surface of the push block 11 will be squeezed by the PCB board 12 and recovered into the inner cavity 9, thereby ensuring the normal recovery of the L-shaped end seat 8.

[0027] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
