[0002] At present, most of the flipping mechanisms on the market use cylinders to drive connecting rods to achieve a 90° flip of the mechanism. Although this mechanism is relatively simple, it is necessary to flip the fixed components (carriers, clamps, etc.) together with the product during the flipping process, which requires a high stroke length of the cylinder's ejection force, which increases costs and takes up a lot of space, and is prone to pinching and damaging products. In addition, it takes a long time to complete a whole rotation action, which cannot adapt to the current production of ultra-high-speed and high-precision parts. Utility Model Content

[0008] The buffer is arranged on the slide groove and is used for contacting with the 90° buffer block.

[0009] Furthermore, the product fixing mechanism includes: an air pipe joint, a product carrier, a material pressing block, a spring, a slide cylinder, a spring pressure plate, a material pressing fixing plate and a cylinder fixing plate;

[0015] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0016] (1) The utility model proposes a 90° simultaneous flipping mechanism for multiple products to solve the shortcomings of the existing flipping mechanism, such as low space utilization, long action cycle, inability to flip multiple products at the same time, and low work efficiency. The utility model uses a gear rack transmission to replace the traditional connecting rod mechanism. Compared with the traditional cylinder connecting rod mechanism, the gear rack transmission has a large transmission power and a constant transmission ratio, which ensures precision and has stable and reliable operation. It drives the rotating shaft to rotate while flipping, which greatly saves the working space and reduces the time and space costs.

Among them, the product carrier 6 uses the air pipe joint 1 to connect the vacuum generator to the outside to adsorb the product, and the limit block 2 is used to limit the position of the stopper 16.

[0023] The limit block 2, the bearing seat assembly 4, the cylinder fixing plate 12 and the slide groove 18 are all fixed on the mounting plate 3. Specifically, the bearing seat assembly 4 arranged in pairs is arranged at the upper end of the mounting plate 3, the cylinder fixing plate 12 is arranged at the lower end of the mounting plate 3, the limit block 2 is arranged in pairs at the upper end of the mounting plate 3 and is located on the inner side of the bearing seat assembly 4; the slide groove 18 is arranged at the upper end of the mounting plate 3 and is located on the outer side of a bearing seat assembly 4.

One end of the rotating shaft 5 passes through a bearing seat assembly 4 and then extends outward to pass through a circular ring 24, a fixing ring 23, a gear 22 and a 90° buffer block 15 in sequence, that is, the circular ring 24, the fixing ring 23, the gear 22 and the 90° buffer block 15 are all fixed on the rotating shaft 5 in sequence.

[0025] A plurality of press blocks 7 are provided on the press fixing plate 11, which is fixed on the slide cylinder 9. The end of each press block 7 is connected to the upper surface of the spring press plate 10 through the spring 8, and the spring press plate 10 is fixed on the lower surface of the press fixing plate 11. The slide cylinder 9 is fixed on the mounting plate 3 through the cylinder fixing plate 12.

[0026] The rack 17 is arranged on the slider 14, and the slider 14 is located in the slide slot 18. The rack 17 cooperates with the gear 22.

The 90° buffer block 15 of this embodiment includes a buffer block body, a first buffer block arranged on the buffer block body, and a second buffer block arranged at 90° with the first buffer block.

Compared with the traditional cylinder connecting rod mechanism, it has a large transmission power, a constant transmission ratio, and a stable and high reliability. The product carrier 6 can be replaced in advance according to the required products. The vacuum suction method is adopted to avoid direct contact with the product and prevent damage to the product.
