DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Figures 1 to 5 A specific embodiment of the 180-degree flipping mechanism of the utility model is shown, which includes a mounting seat 1, a motor 2, an air gripper 3, a sliding seat 4 and a slide rail 5. The motor 2 and the slide rail 5 are both located on the mounting seat 1, and the motor 2 is located below the slide rail 5. The slide rail 5 is an arc-shaped track with an opening downward, such as a U-shaped slide rail or a semicircular arc-shaped slide rail. The air gripper 3 is slidably arranged on the slide rail 5 through the slide seat 4. The motor 2 is connected to the slide seat 4 through a rotating connecting rod 6 to drive the slide seat 4 to move along the slide rail 5. The 180-degree flipping mechanism of this embodiment uses the air gripper 3 to clamp the product to be flipped, and the motor 2 drives the slide seat 4 to move along the slide rail 5 with the air gripper 3 and the clamped product. Since the slide rail 5 is an arc-shaped track, when the product rises, moves, and descends from one end of the slide rail 5 along the arc-shaped track to the other end, a 180-degree flip is achieved. The flipping mechanism only needs one air gripper 3 and one motor 2 to flip and translate the product 180 degrees. The structure is simple and practical, and relatively few standard parts and machined parts are used, thus achieving the design goals of economy, effectiveness and practicality.

[0025] The specific working process of the 180-degree flip mechanism of this embodiment is as follows:

[0026] Taking the U-shaped slide rail with the opening downward as an example, the vertical direction is defined as the Z axis and the horizontal direction as the X axis. After the end air gripper 3 is used to clamp the product, the motor 2 drives the sliding seat 4 to move along the Z axis track. After reaching a certain height, the Z axis track changes to the X axis track, and the sliding seat 4 drives the product to flip 90 degrees. The end of the X axis track switches back to the Z axis track, and the sliding seat 4 drives the product to flip 90 degrees again, and then descends to the specified position, thereby achieving the purpose of 180-degree flipping and translation.

[0027] Furthermore, in this embodiment, the sliding seat 4 includes a connecting plate 41 and two follower bearings 42 fixed on the connecting plate 41, and the air claw 3 is fixed on the connecting plate 41. The use of two follower bearings 42 as sliding components of the sliding seat 4 can effectively reduce sliding friction and make the flipping process smoother. Of course, in other embodiments, a slider (as long as it is not circular and cannot rotate) can be used to replace the sliding seat 4 and cooperate with the slide rail 5, but the friction will be significantly increased.

[0028] Furthermore, in this embodiment, the gripping end 31 of the air gripper 3 faces downward, a suspension beam 32 is fixed to the back of the air gripper 3, a bearing such as a seat bearing 63 is provided at one end of the rotating connecting rod 6, one end of the suspension beam 32 passes through the seat bearing 63 and is fixedly connected to the connecting plate 41, and the connection between the suspension beam 32 and the connecting plate 41 is located between the two follower bearings 42. The gripping end 31 of the air gripper 3 faces downward, which facilitates the air gripper 3 to quickly clamp the product from above the product. The air gripper 3 is installed by using the suspension beam 32, so that a certain distance can be kept between the air gripper 3 and the mounting seat 1 to avoid hindering the rotation of the rotating connecting rod 6, reduce the space restriction on the product to be flipped, and is applicable to a wider range of product sizes.

[0029] Furthermore, in this embodiment, the arc track is a U-shaped track, and the rotating link 6 is a retractable link. The U-shaped track is used to facilitate the design of the translation distance of the product according to actual needs such as the limitation of the assembly site, and the rotating link 6 is designed as a retractable link to better solve the problem of unequal rotation radius. Of course, if a semicircular arc slide rail is used, the rotating link 6 does not need to be set to be retractable.

[0030] Furthermore, in this embodiment, the telescopic connecting rod includes a sliding rod 61 and a first sliding groove 62 that cooperate with each other, the sliding rod 61 is connected to the sliding seat 4, and the first sliding groove 62 is connected to the motor 2. Of course, in other embodiments, the telescopic connecting rod may also include a connecting rod and a sliding block, the back of the connecting rod is provided with a second sliding groove that cooperates with the sliding block, and the sliding block is connected to the motor 2.

[0031] Furthermore, in this embodiment, it also includes a transmission shaft 7, a transmission belt 71, a first transmission wheel 72 and a second transmission wheel 73. The first transmission wheel 72 is located at the output end 21 of the motor 2 such as a servo motor. The first end of the transmission shaft 7 is fixedly connected to the second transmission wheel 73, and the second end is vertically connected to the first slide groove 62 or the slider. The first transmission wheel 72 and the second transmission wheel 73 are connected through the transmission belt 71. The motor 2, the synchronous wheel (i.e., the second transmission wheel 73) and the transmission belt 71 are used to drive the sliding seat 4, the air claw 3 and the product to rise, translate and descend along the slide rail 5 to achieve flipping, with good stability and high reliability. Because the transmission belt 71 has good elasticity, the transmission is stable during operation, and it can buffer and absorb vibration; if it encounters overload during operation, the transmission belt 71 will slip, which can prevent weak parts from being damaged and can play a role in safety protection; in addition, the length of the transmission belt 71 is optional, which is conducive to reducing the installation requirements for the position of the motor 2.

[0032] Further, in this embodiment, the mounting seat 1 includes a support frame 11 and a mounting plate 12 fixed to the top of the support frame 11, the slide rail 5 is located on the mounting plate 12, the motor 2 is installed on the upper part of the support frame 11, and the output end 21 of the motor 2 is located behind the support frame 11, the second transmission wheel 73 is located behind the mounting plate 12, and the second end of the transmission shaft 7 passes through the mounting plate 12 and is connected to the first slide groove 62 or the slider. This installation method makes reasonable use of space and will not interfere with the movement in front of the mounting plate 12.

[0033] Furthermore, in this embodiment, the second end of the transmission shaft 7 is vertically connected to a fixing plate 74, the fixing plate 74 is fitted with the mounting plate 12, and the first slide groove 62 or the slider is mounted on the fixing plate. Compared with directly connecting with the second end of the transmission shaft 7, using the fixing plate 74 to mount the first slide groove 62 or the slider is conducive to improving the overall strength.

[0034] Furthermore, in this embodiment, a connecting bracket 8 is provided on the back of the mounting plate 12, and the connecting bracket 8 includes a bottom frame 81 and two side frames 82. The bottom frame 81 is vertically connected to the bottom edge of the mounting plate 12, and the two side frames 82 are respectively fixed at the angles formed by the back of the mounting plate 12 and the two sides of the bottom frame 81. An axis bracket 83 is also provided on the bottom frame 81, and the axis bracket 83 is used to support the transmission shaft 7, thereby making the support of the transmission shaft 7 more stable.

[0035] Furthermore, in this embodiment, limit sensors 9 such as photoelectric sensors are respectively provided at both ends of the slide rail 5 to facilitate automatic control of the flipping mechanism.

Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
