[0029] Please refer toFigure 1 、 4 , it is a structure schematic view of a turnover mechanism 100 provided by an embodiment of the utility model.

[0030] The turnover mechanism 100 includes: a mounting seat 10, a load connecting block 20 rotationally connected to the mounting seat 10 and a driving assembly 30 rotationally connected to the mounting seat 10; the load connecting block 20 is used to be connected to external load and drive the load to rotate, the driving assembly 30 is used to drive the load connecting block 20 to rotate, and the load connecting block 20 and the driving assembly 30 are both rotationally installed on the mounting seat 10.

[0031] In actual application scenarios, the turnover mechanism 100 is mainly used to drive small load to rotate, and the small load is relatively light in weight, and the requirements for driving force and anti-buffering are relatively low, mainly considering that the turnover mechanism 100 needs to minimize the space occupation. Therefore, for the overall turnover mechanism 100, the posture and motion trajectory during the turnover action need to be considered in the scenario of small space occupation to avoid interference when the tooling and the product or the tooling matched therewith interact.

[0032] In one embodiment, the load connecting block 20 has a first connecting part 21 and a second connecting part 22, the first connecting part 21 is rotationally installed on the mounting seat 10 through a first rotating shaft 41, and the second connecting part 22 is rotationally connected to a driving rod 33 of the driving assembly 30. Figures 2-3 , 5-6 the driving assembly 30 includes a cylinder 31 and a telescopic rod 32, the driving rod 33 is connected to the telescopic rod 32, the telescopic rod 32 does linear motion while driving the driving rod 33 to do linear motion, and the driving rod 33 is rotationally connected to the load connecting block 20 to convert the linear motion of the driving assembly 30 into rotary motion.

[0033] The turnover mechanism 100 has a first state, the driving rod 33 has a first position, the turnover mechanism 100 has a second state, the driving rod 33 has a second position, and the first rotating shaft 41 is located on the perpendicular bisector of the line connecting the first position and the second position. Specifically, the first state is the state when the load connecting block 20 is clamped and combined with the mounting seat 10, and the second state is the state when the load connecting block 20 is opened relative to the mounting seat 10.

[0034] It can be understood that the mounting seat 10 is relatively fixed, the first connecting part 21 of the load connecting block 20 is rotationally connected to the mounting seat 10 through the first rotation shaft 41, which is equivalent to that the second connecting part 22 of the load connecting block 20 rotates around the first rotation shaft 41. It can be understood that the first rotation shaft 41 is the center of a circle, and the second connecting part 22 forms an arc track during rotation. The center of the circle must be located on the perpendicular bisector of the line connecting the two endpoints of the arc track of the second connecting part 22. Therefore, when the second connecting part 22 is directly connected to the driving rod 33, in other words, the first rotation shaft 41 is located on the perpendicular bisector of the line connecting the two endpoints of the movement track of the driving rod 33.

[0035] The driving rod 33 is a Y-shaped connecting rod, and the second connecting part 22 is connected to the Y-shaped connecting rod through the second rotation shaft 42, and the second rotation shaft 42 passes through the second connecting part 22 and the driving rod 33. The driving rod 33 has a first position, which means the position of the second rotation shaft 42 in the first state. The driving rod 33 has a second position, which means the position of the second rotation shaft 42 in the second state.

[0036] By optimizing the positions and structures of the first rotation shaft 41 and the second rotation shaft 42, smooth and efficient overturning of the overall overturning structure 100 is achieved. Through scientific rotation point layout, the stability of the structure and the fluency of the movement during overturning are ensured. More specifically, placing the first rotation shaft 41 on the perpendicular bisector of the line connecting the two endpoint positions of the driving rod 33 in motion can keep the overall structure balanced during overturning and avoid movement deviation or vibration problems caused by improper rotation point position.

[0037] In one embodiment, the driving assembly 30 includes a thin air cylinder, the stroke of the thin air cylinder is less than 50 mm, and the overturning angle of the load connecting block 20 from the first state to the second state is less than 70 degrees. It can be understood that the application of the thin air cylinder is mainly used to drive small load overturning, and the overturning angle is small, mainly considering reducing the space occupation.

[0038] By adopting the thin air cylinder and the matching load connecting block 20 design, the extension and retraction functions of the air cylinder extension rod are used to realize the clamping or opening operation of the load connecting block 20, which saves the space occupation of the tooling and significantly reduces the weight requirement of the tooling. Optimizing the structural design of the tooling improves the flexibility of the overturning mechanism 100 installation and use, and provides a more efficient and compact solution for the design and application of tooling.

[0039] In theory, the thin cylinder applied to small load overturning currently has four cylinder diameters of 32 / 40 / 50 / 63mm, the 32 / 40mm cylinder diameter is generally used in the place where the weight is limited or the space is small or the required pressure is general, and is generally directly connected with a load connecting block 20; for the 63mm cylinder diameter, it is generally used in all places where the pressure is large or the distance between two or three load connecting blocks 20 can be connected by adding the load connecting block 20, that is, a driving rod 33 drives multiple load connecting blocks 20 to move.

[0040] In practice, the stroke of the thin cylinder adopted by the small overturning mechanism 100 currently is divided into two kinds of 25 / 50mm, and the stroke of 25mm retains a stroke allowance of 5mm; for the 32 / 40 / 50 / 63mm cylinder diameter, the load connecting block 20 can be overturned by 32° / 28° / 25° / 21° respectively; for the stroke of 50mm, a stroke allowance of 5mm is retained; for the 32 / 40 / 50 / 63mm cylinder diameter, the load connecting block 20 can be overturned by 65° / 59° / 53° / 46° respectively. It can be understood that the overturning angle shown in the drawing does not completely represent the actual overturning angle.

[0041] In another embodiment, the driving assembly 30 includes a standard cylinder, the stroke of the standard cylinder is greater than 100mm; the overturning angle of the load connecting block 20 from the first state to the second state is not less than 80° and not greater than 90°.

[0042] It can be understood that the utility model is mainly used in the application scene of small load overturning, but it does not mean that it cannot be applied to large load with slightly larger weight at all, and it can be adjusted according to the actual situation, so that the utility model can also use a standard cylinder to be applicable to the scene where the driving force requirement is a little higher, in combination with Figures 9-10 As shown in the figure, the overturning mechanism 100 includes a mounting seat 10, a load connecting block 20 and a driving assembly 30, and the driving assembly 30 includes a standard cylinder, since it is applied to the application scene of large load overturning, the overturning mechanism 100 can be further provided with a limiting assembly 70, a buffer assembly 80 and the like, and other specific structures will not be described in detail herein.

It can be understood that the first rotating shaft 41 penetrates through the mounting walls 11 and the first connecting part 21, in the first state, the first abutting surface 211 of the first connecting part 21 abuts against the bottom surface supported in the receiving space 110, and in the second state, the second abutting surface 212 of the first connecting part 21 abuts against the bottom surface supported in the receiving space 110.
