Description

Technical Field

[0001] The invention relates to the technical field related to assembly line processing, and in particular to an equidistant rotating transport mechanism. Background Art

[0002] In assembly line processing equipment such as automotive electronics and new energy, when processing materials such as water-cooled plates, batteries, and metal shells, multiple products need to be moved and flipped at the same time.

[0003] Traditional flipping and handling equipment often uses different power controls for flipping and handling. If multiple stations need to be flipped, multiple flipping drive mechanisms need to be added. Although some mechanisms use synchronous belts and pulleys to control multiple flipping stations in parallel, at least two power sources are still required, which increases the cost of the equipment and makes the control complicated. In addition, since the consistency of the control of the two power sources cannot be guaranteed, the order of movement is generated, resulting in the flipping and handling process being not smooth enough, causing bumps to the products and affecting the yield rate.

[0004] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create an equidistant rotating transport mechanism to make it more valuable for industrial use. Summary of the invention

[0016] By means of the above scheme, the present invention has at least the following advantages:

[0028] like Figure 1 to Figure 3 As shown, an equidistant rotating transport mechanism includes a lower support plate 1 and an upper support plate 2 from top to bottom. A transport base plate 5 is installed on the upper support plate 2, and a transport stand 7 is installed at the rear end of the transport base plate 5. The driving end of the linear motor module 3 installed on one side of the lower support plate 1 is connected to the right side of the transport base plate 5 through a linear drive connector 4. A transport guide rail 6 distributed along the left and right direction is installed on the upper support plate 2 below the transport base plate 5, and a transport slider at the bottom of the transport base plate 5 is connected to the transport guide rail 6 below.

[0029] Among them, the linear drive connecting member 4 includes a propulsion plate 18, a cam mounting plate 19, a propulsion cam slot plate 21 and a propulsion connecting plate 23. The propulsion plate 18 is connected to the driving end of the linear motor module 3. The cam mounting plate 19 is installed at the rear end of the propulsion plate 18. The propulsion connecting plate 23 is connected to the transport base plate 5. The propulsion cam slot plate 21 is installed at the front end of the propulsion connecting plate 23. The first cam follower 20 is installed at the rear end of the cam mounting plate 19. The propulsion cam slot plate 21 is provided with a propulsion cam slot 22 which is compatible with the above-mentioned first cam follower 20.

[0030] A clamping unit is installed at the rear end of the transport frame 7, and the clamping unit includes a plurality of fixed clamps 9 and a plurality of rotating clamps 12. The fixed clamps 9 are installed on the transport frame 7 through the fixed clamp mounting seat 8, and the rotating clamps 12 are installed on the rotating clamp mounting seat 11. The rotating clamp mounting seat 11 is connected to the rear end of the clamp rotating shaft 25. The front end of the clamp rotating shaft 25 passes through the transport frame 7 and is connected to the first side of the flip mounting plate 31. A second cam follower 33 is installed on the second side of the flip mounting plate 31. The second cam follower 33 is connected to the rotating cam groove 32 in the rotating cam vertical plate 10 at the front end. The rotating cam vertical plate 10 is installed on the upper support plate 2 at the front end of the transport frame 7.

[0031] Among them, a bearing seat 24 is installed on the transport stand 7 at the front end of the rotating clamp mounting seat 11, a first shaft ring 27 is installed on the outer side of the rear end of the clamp rotating shaft 25, and a second shaft ring 30 is installed on the outer side of the front end of the clamp rotating shaft 25. The rear end of the first shaft ring 27 is connected to the bearing seat 24 through the first bearing 26, and the rear end of the second shaft ring 30 is installed on the transport stand 7 through the second bearing 29 and the bearing end cover 28.

[0032] Several support frames 13 are evenly distributed along the left and right directions on the lower support plate 1, and support guide rails 15 distributed along the vertical direction are installed on the support frames 13. The front end of the upper support plate 2 is connected to the support guide rails 15 through a support slider 16 installed on a support connection block 17. Support reinforcement ribs 14 are installed on the lower support plate 1 on one side of the support frame 13. A lifting module for lifting the upper support plate 2 above is also installed on the lower support plate 1.

[0033] The working process of the present invention is briefly described as follows:

[0034] First, the linear motor module 3 is started, and advances layer by layer through the push plate 18, the cam mounting plate 19, the push cam slot plate 21 and the push connecting plate 23 on the linear drive connector 4, and finally drives the transport base plate 5 to slide left and right on the upper support plate 2.

[0035] The fixed clamping claw 9 that does not need to be turned over moves linearly along with the conveying base plate 5 .

[0036] The rotating clamp 12 that needs to be flipped is connected to the flip mounting plate 31 through the clamp rotating shaft 25. The other end of the flip mounting plate 31 is connected to the second cam follower 33. The cam of the second cam follower 33 is inscribed in the rotating cam groove 32 of the rotating cam vertical plate 10. The rotating cam vertical plate 10 is installed on the upper support plate 2. Therefore, when the transport stand 7 moves, the second cam follower 33 will roll in the rotating cam groove 32 of the rotating cam vertical plate 10 under the action of the system thrust. The rotating cam groove 32 is V-shaped. When the cam of the second cam follower 33 moves to the lower slope of the rotating cam groove 32, a tangential force will be generated to drive the flip mounting plate 31 to rotate, driving the rotating clamp 12 to rotate together. When the cam of the second cam follower 33 moves to the lowest point of the rotating cam groove 32, it is the dead point position of the connecting rod structure, so the flipping The spacing between the two holes of the mounting plate 31 that respectively connect the clamping jaw rotating shaft 25 and the second cam follower 33 should be exactly equal to the height of the cam of the second cam follower 33 moving in the Z direction in the rotating cam groove 32. When it reaches the dead point, the flip mounting plate 31 is exactly in a vertical state, but relying on acceleration and inertia, the cam can continue to roll upward on the slope beyond the dead point, and then it can still drive the rotating clamping jaw 12 to continue rotating in the original direction of rotation through the tangential force until it reaches the horizontal plane. During this whole process, the clamping jaw just flips 180 degrees. The rotating clamping jaw 12 and the clamping jaw rotating shaft 25 also follow the transport stand 7 to make a linear motion in the above action. The superposition of the above two actions realizes the synchronous completion of the flipping action during the lateral movement.

[0037] At this point, the equidistant rotation and handling work is completed.

[0038] Only one power source is used, and a cam-link mechanism is adopted to realize the flipping while the mechanism is being transported, and it is compatible with multiple flipping positions, thus simplifying the structure of the equidistant flipping transport device;

[0039] At the same time, it saves power sources, eliminates the coordination and adjustment process between multiple power sources, improves the efficiency of handling and flipping, reduces the cost of equipment, ensures the stability of the movement process, and improves the yield rate.
