[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0042] Combine the following Figures 1 to 5 The specific embodiments of the present invention are described in detail.

[0043] The present embodiment provides a synchronous turning mechanism for sheet products, including an original station 100, a transfer station 200 and a waiting transfer station 300, and is provided with a material unloading transfer mechanism 1, a turning mechanism 2, a positioning mechanism 3 and a material loading transfer mechanism 4.

[0044] It should be noted that the original workstation 100 is a workstation that already exists in the original assembly production line. In actual use, a workstation platform should be provided at the original workstation 100. The previous process places the unturned products on the workstation platform, and the next process takes the turned products away from the workstation platform; the transfer station 200 is a workstation added by this mechanism, and its function is to realize the docking of the flipping mechanism 2 with the unloading and transferring mechanism 1. The transfer station 200 does not need to be equipped with a corresponding platform, and the flipping mechanism 2 can be directly docked with the unloading and transferring mechanism 1; the waiting transfer station 300 is also a workstation added by this mechanism, and its function is to realize the docking of the loading and transferring mechanism 4 with the flipping mechanism 2. The positioning mechanism 3 is arranged at the waiting transfer station 300, and it has two purposes: one is to realize the positioning of the product; the other is to serve as a transfer structure to realize the indirect docking of the flipping mechanism 2 with the loading and transferring mechanism 4.

[0045] Among them, the material unloading and transferring mechanism 1 includes a material unloading drive component 11 and a material unloading suction cup 12. The material unloading suction cup 12 is arranged at the output end of the material unloading drive component 11. The adsorption surface of the material unloading suction cup 12 faces downward and is arranged horizontally. The material unloading drive component 11 is used to drive the material unloading suction cup 12 to pick up materials at the original station 100 and discharge materials at the transfer station 200.

[0046] Specifically, the material unloading drive assembly 11 includes a material unloading linear drive pair 111 and a material unloading lifting drive pair 112; the material unloading linear drive pair 111 is used to output the reciprocating motion between the original station 100 and the transfer station 200; the fixed part of the material unloading lifting drive pair 112 is arranged on the moving part of the material unloading linear drive pair 111, and the moving part of the material unloading lifting drive pair 112 is connected to the material unloading suction cup 12. When in motion, the material unloading linear drive pair 111 drives the material unloading lifting drive pair 112 and the material unloading suction cup 12 to reciprocate linearly between the original station 100 and the transfer station 200 as a whole, and the material unloading lifting drive pair 112 drives the material unloading suction cup 12 to rise and fall to complete the material picking action at the original station 100 and complete the material unloading action at the transfer station 200.

[0047] More specifically, the material unloading linear drive pair 111 is a synchronous belt assembly, the material unloading lifting drive pair 112 is a telescopic cylinder, the cylinder body of the telescopic cylinder is fixedly connected to the synchronous belt of the synchronous belt assembly, and the material unloading suction cup 12 is fixedly connected to the piston rod of the telescopic cylinder. In detail, in the specific design, guide rails can be added to improve the motion accuracy of the reciprocating linear motion; sensors can also be added at both ends of the reciprocating linear motion to improve the position accuracy of the reciprocating linear motion at the end points.

[0048] Among them, the flipping mechanism 2 includes a flipping drive component 21 and a flipping suction cup 22. The flipping suction cup 22 is arranged at the output end of the flipping drive component 21. The flipping suction cup 22 has a material-bearing state with the adsorption surface facing upward and arranged horizontally and a material-discharging state with the adsorption surface facing downward and arranged horizontally. The flipping drive component 21 is used to drive the flipping suction cup 22 to pick up materials at the transfer station 200 in the material-bearing state and to discharge materials at the transfer station 300 in the material-discharging state.

[0049] Specifically, the flipping drive assembly 21 includes a flipping linear drive pair 211, a flipping lifting drive pair 212 and a rotating drive pair 213; the flipping linear drive pair 211 is used to output reciprocating motion between the transfer station 200 and the transfer station 300; the fixed part of the flipping lifting drive pair 212 is arranged on the moving part of the flipping linear drive pair 211; the axis of the rotating drive pair 213 is arranged horizontally, and the fixed part of the rotating drive pair 213 is arranged on the moving part of the flipping lifting drive pair 212, and the rotating part of the rotating drive pair 213 is connected to the flip suction cup 22. During operation, the flip linear drive pair 211 drives the flip lifting drive pair 212, the rotation drive pair 213 and the flip suction cup 22 to move back and forth linearly between the transfer station 200 and the transfer station 300. The flip lifting drive pair 212 drives the rotation drive pair 213 and the flip suction cup 22 to lift and lower as a whole to receive the discharge of the unloading suction cup 12 at the transfer station 200 and discharge the material at the transfer station 300. The rotation drive pair 213 drives the flip suction cup 22 to complete the flipping of the product during the horizontal linear motion.

[0050] More specifically, the flip linear drive pair 211 is a linear module, the flip lifting drive pair 212 is a telescopic cylinder, the rotation drive pair 213 is a rotary cylinder, the slider of the linear module is fixedly connected to the cylinder body of the telescopic cylinder, the piston rod of the telescopic cylinder is fixedly connected to the cylinder body of the rotary cylinder, and the rotary shaft of the rotary cylinder is fixedly connected to the flip suction cup 22. In detail, in the specific design, sensors can be added at both ends of the reciprocating linear motion to improve the position accuracy of the reciprocating linear motion at the end points.

[0051] The positioning mechanism 3 is disposed at the waiting position 300 and is used to carry and position the product.

[0052] It should be noted that since the adsorption surface of the flip suction cup 22 faces downward after the product is turned over, and the adsorption surface of the loading suction cup 42 also faces downward, the positioning mechanism 3 is required as a transfer structure to temporarily carry the product, and then dock the flip suction cup 22 and the loading suction cup 42 respectively, so as to achieve indirect docking of the flip suction cup 22 and the loading suction cup 42.

[0053] Specifically, the positioning mechanism 3 includes a positioning platform 31 and a clamping assembly 32; the clamping assembly 32 is provided with at least two pairs and both are located at the edge of the positioning platform 31, each pair of clamping assemblies 32 is symmetrically arranged on the opposite side of the positioning platform 31, and all pairs of clamping assemblies 32 cooperate to clamp and position the product. When in action, the flipping suction cup 22 places the flipped product on the positioning platform 31, and all pairs of clamping assemblies 32 are simultaneously activated to clamp and position the product and then release it, waiting for the loading suction cup 42 to pick up the positioned product.

[0054] More specifically, in this embodiment, the product is rectangular, so the positioning platform 31 is designed to be rectangular, and two pairs of clamping components 32 are provided and are respectively located at two opposite sides of the rectangle. Of course, if the length and width of the rectangle are relatively large, two pairs of clamping components 32 can be provided corresponding to the long sides of the rectangle; if the product is a pentagon or other shape, the positioning platform 31 can be designed to match the product, and the number and position of the clamping components 32 can be determined according to the adaptability of the product shape.

[0055] More specifically, the clamping assembly 32 includes a clamping cylinder 321 and a positioning block 322 . The positioning block 322 is disposed at the output end of the clamping cylinder 321 . The cylinder body of the clamping cylinder 321 is fixed relative to the positioning platform 31 . The piston rod of the clamping cylinder 321 is fixedly connected to the positioning block 322 .

[0056] Among them, the loading and transferring mechanism 4 includes a loading drive component 41 and a loading suction cup 42. The loading suction cup 42 is arranged at the output end of the loading drive component 41. The adsorption surface of the loading suction cup 42 faces downward and is arranged horizontally. The loading drive component 41 is used to drive the loading suction cup 42 to pick up materials on the positioning mechanism 3 of the transfer station 300 and put the materials at the original station 100.

[0057] Specifically, the feeding drive assembly 41 includes a feeding linear driving pair 411 and a feeding lifting driving pair 412; the feeding linear driving pair 411 is used to output the reciprocating motion between the original station 100 and the waiting station 300; the fixed part of the feeding lifting driving pair 412 is arranged on the moving part of the feeding linear driving pair 411, and the moving part of the feeding lifting driving pair 412 is connected to the feeding suction cup 42. When in motion, the feeding linear driving pair 411 drives the feeding lifting driving pair 412 and the feeding suction cup 42 to reciprocate linearly between the waiting station 300 and the original station 100, and the feeding lifting driving pair 412 drives the feeding suction cup 42 to rise and fall to complete the material picking action at the waiting station 300 and complete the material placing action at the original station 100.

[0058] More specifically, the feeding linear drive pair 411 is a synchronous belt assembly, the feeding lifting drive pair 412 is a telescopic cylinder, the cylinder body of the telescopic cylinder is fixedly connected to the synchronous belt of the synchronous belt assembly, and the feeding suction cup 42 is fixedly connected to the piston rod of the telescopic cylinder. In detail, in the specific design, guide rails can be added to improve the motion accuracy of the reciprocating linear motion; sensors can also be added at both ends of the reciprocating linear motion to improve the position accuracy of the reciprocating linear motion at the end points.

[0059] Furthermore, the unloading linear drive pair 111 and the loading linear drive pair 411 of this embodiment are both synchronous belt assemblies, the first ends of the two sets of synchronous belt assemblies are wound on the same pulley and the lengths of the two sets of synchronous belt assemblies are equal, the second end of one set of synchronous belt assemblies is connected to a driving member 5, the flip mechanism 2 is located between the second ends of the two sets of synchronous belt assemblies, and the original station 100, the transfer station 200 and the station to be transferred 300 are all located in the isosceles triangle area surrounded by the two sets of synchronous belts and the flip mechanism 2. This improved structure has two advantages: first, the unloading linear drive pair 111 and the loading linear drive pair 411 share the same driving member 5, the structural cost is lower, and the synchronization of the two synchronous belt assemblies is easier to ensure; second, the two sets of synchronous belts and the flip mechanism 2 surround an isosceles triangle area, and the original station 100, the transfer station 200 and the station to be transferred 300 are all arranged in the isosceles triangle area, the spatial layout is more reasonable, and the overall structure occupies less space.

[0060] Specifically, the driving member 5 includes a servo motor, and an output shaft of the servo motor is connected to a driving pulley of the synchronous belt assembly.

[0061] Specifically, the original workstation 100 is set corresponding to the vertex of the isosceles triangle area, the transfer station 200 and the to-be-transferred station 300 are respectively set corresponding to the two waists of the isosceles triangle area, and the distance between the to-be-transferred station 300 and the corresponding waist is greater than the distance between the transfer station 200 and the corresponding waist. The loading drive assembly 41 also includes a compensating linear drive pair 413, and the fixed part of the compensating linear drive pair 413 is arranged on the moving part of the loading lifting drive pair 412, and the moving part of the compensating linear drive pair 413 is connected to the loading suction cup 42. Since the waiting transfer station 300 is provided with a positioning mechanism 3, and the transfer station 200 does not need to be provided with a platform, the waiting transfer station 300 requires a larger installation space, and the original station 100 is provided at the vertex of the isosceles triangle area. If the turned product is translated to the original station 100 only by the feeding linear drive pair 411, the original station 100 also needs to maintain a large distance from the waist of the isosceles triangle area, which makes it impossible for the original station 100 to be located in the vertex area of ​​the isosceles triangle area, resulting in a larger space area occupied by the overall structure. This embodiment can compensate for the defect of the large distance between the waiting transfer station 300 and the corresponding waist by adding a compensating linear drive pair 413 to the feeding drive assembly 41, so that the original station 100 can be located in the vertex area of ​​the isosceles triangle area, thereby making the overall structure occupy a smaller space area.

[0062] The working process of the synchronous turning mechanism of the sheet product of this embodiment is as follows:

[0063] S1. The previous process places the product to be turned over on the original station platform 100;

[0064] S2. The unloading linear drive pair 111 moves the unloading suction cup 12 to the top of the original station 100, the unloading lifting drive pair 112 moves the unloading suction cup 12 down to contact the product, the unloading suction cup 12 picks up the product, and then the unloading lifting drive pair 112 moves the unloading suction cup 12 up, then the unloading linear drive pair 111 moves the unloading suction cup 12 to the transfer station 200, when the unloading suction cup 12 moves to the transfer station 200, the flip suction cup 22 has arrived at the transfer station 200, and finally the unloading lifting drive pair 112 moves the unloading suction cup 12 down and places the product on the transfer suction cup;

[0065] S3. The flip linear drive pair 211 moves to make the flip suction cup 22 move linearly toward the transfer station 300. During the movement, the rotation drive pair 213 moves to complete the flipping of the product. When the flip suction cup 22 reaches the top of the positioning platform 31 of the transfer station 300, the flip lifting drive pair 212 moves to make the flip suction cup 22 descend and place the flipped product on the positioning platform 31.

[0066] S4. The clamping assembly 32 moves to clamp the product and release it. At this time, the loading suction cup 42 has reached the transfer station 300;

[0067] S5. The loading lifting drive pair 412 moves to make the loading suction cup 42 descend to contact the turned-over product, and the loading suction cup 42 picks up the turned-over product. Then the loading lifting drive pair 412 moves to make the loading suction cup 42 rise. Then the loading linear drive pair 411 moves to make the loading suction cup 42 move to the original station 100. Finally, the loading lifting drive pair 412 moves to make the loading suction cup 42 descend and place the turned-over product on the station platform of the original station 100.

[0068] S6. The next process robot picks up the turned product from the workstation platform of the original workstation 100 and transfers it to the next process.

[0069] It should be noted that the unloading transfer mechanism 1, the flipping mechanism 2 and the loading transfer mechanism act synchronously during actual operation, that is, when the unloading suction cup 12 moves from the original station 100 to the transfer station 200, the flipping suction cup 22 returns from the waiting station 300 to the transfer station 200, and the loading suction cup 42 moves from the waiting station 300 to the original station 100; when the unloading suction cup 12 arrives at the transfer station 200, the flipping suction cup 22 also arrives at the transfer station 200. When the unloading suction cup 12 returns from the transfer station 200 to the original station 100, the flip suction cup 22 moves from the transfer station 200 to the waiting station 300, and the loading suction cup 42 returns from the original station 100 to the waiting station 300; when the unloading suction cup 12 arrives at the original station 100, the flip suction cup 22 arrives at the waiting station 300, and the loading suction cup 42 arrives at the waiting station 300. Although the unloading suction cup 12, the loading suction cup 42 and the flip suction cup 22 act synchronously, they do not interfere with each other.

[0070] The above is only a specific implementation of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
