The traditional flip structure is generally to clamp the module and then flip it 180 degrees and put it back to its original position, or add many cylinders to the rotating mechanism to clamp it, and then the cylinder or servo drive flips;

The left clamping jig and the right clamping jig are connected to the flip connecting plate through a first quick-change knob. Flip synchronous wheels are movably installed between two of the first X-guide rails in one group and between two of the second X-guide rails in one group. A flip synchronous belt is sleeved on the periphery of the two flip synchronous wheels. A second connecting block is fixedly connected between the bottom of the first base plate and the second base plate and the flip synchronous belt, and a tensioning block is installed on the outer end of the rotating shaft of one of the flip synchronous wheels.

[0007] As a further solution of the present invention, the end of the linear bearing is connected to the flip connection plate in the second base plate, and the two flip connection plates are fixedly installed with the left clamping fixture and the right clamping fixture respectively.

[0008] As a further solution of the present invention, the left clamping fixture and the corresponding flip connecting plate are fixedly connected to the output shaft of the reducer, and the right clamping fixture and the corresponding flip connecting plate are movably rotatably arranged on the top of the second bottom plate through the flip shaft.

[0009] As a further solution of the present invention, the first base plate and the second base plate are respectively slidably arranged through a group of first X-guide rails and a group of second X-guide rails, and the first base plate and the second base plate are fixedly connected to the flip synchronous belt through a second connecting block.

[0010] As a further solution of the present invention, a clamping assembly is installed between the top of the first base plate and the second base plate, and the clamping assembly includes two groups of first Y-direction guide rails, and the two groups of first Y-direction guide rails are installed between the top of the first base plate and the second base plate, and the third base plate and the fourth base plate are movably installed on the top of the two groups of first Y-direction guide rails, respectively, a front positioning fixture is fixedly installed on the top of the third base plate, and a rear positioning fixture is installed on the inner side of the fourth base plate, and first positioning wheels are movably installed between the two groups of first Y-direction guide rails, and the outer peripheries of the two first positioning wheels are sleeved with the same flipping synchronous belts, and the third connecting block and the first connecting block are respectively connected and installed between the bottom of the third base plate and the fourth base plate and the flipping synchronous belt, and a positioning cylinder is installed on one side of the third base plate and the fourth base plate, and a second buffer is installed at the end of the positioning cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting a flip servo motor, a flip connecting plate, and a flip connecting shaft, the left clamping fixture and the right clamping fixture clamp the product longitudinally. The flip servo motor drives the left clamping fixture and the right clamping fixture to rotate 180 degrees, which can clamp the product longitudinally and laterally, and complete the positioning and flipping of the product;

[0015] By setting the front positioning fixture and the rear positioning fixture, the product will swing slightly after flipping due to the gear gap of the reducer itself, which will have a great impact on screwing, and it is easy to drive the screw off or the screw will be stuck and cannot be driven in. However, the new mechanism adds a clamping device after flipping, which eliminates this swing gap, thereby greatly improving the accuracy after flipping and meeting the needs of precision screwing;

[0016] By setting up the clamping assembly, when the production line produces products of different models, it only needs to open the first quick-change knob and the second quick-change knob on the left clamping jig, the right clamping jig, the front positioning jig and the rear positioning jig, remove the jig plate, and replace the new corresponding jig plate to complete the model change. The model change is convenient and fast, which greatly saves the production line model change time.

[0017] The novel flipping structure of the present invention has a simple structure, occupies little space, and can be quickly changed according to different product jigs, which greatly improves the efficiency of the production line. In addition, the novel flipping mechanism can also expand other similar product assembly equipment that requires flipping assembly, so it has great market prospects.
