The structure of the flipping and opening mechanism provided by the present application will be elaborated in detail below.

[0033] For a clearer description of the technical solution, define the first direction X, the second direction Y, and the third direction Z as shown in Figure 1 , and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other pairwise.

[0034] Please refer to the following Figures 1 to 3 , Figure 2 , which is a schematic diagram of the initial state of the flip-open cover mechanism. Figure 3 , which is a schematic diagram of the structure of the flip-open cover mechanism after flipping. Figure 2 and Figure 3 The working position 10 and the carrier in

[0035] are only for illustration and do not limit the protection scope of this application. The flip-open cover mechanism includes a frame 1, a fixing plate 11, and a flip plate 12. The fixing plate 11 is installed on the frame 1, and the flip plate 12 is rotatably connected to the fixing plate 11. A working position 10 is provided on one side of the frame 1, and the working position 10 is used to place the carrier. The flip-open cover mechanism further includes a driving component 2, the driving component 2 is arranged on the fixing plate 11, the driving component 2 is in transmission connection with the flip plate 12, and the driving component 2 is configured to drive the flip plate 12 to rotate towards or away from the working position 10. The flip-open cover mechanism further includes a clamping component 4, the clamping component 4 is arranged on the flip plate 12, the clamping component 4 includes a plurality of first clamping jaws 41, two adjacent first clamping jaws 41 are spaced apart on the flip plate 12, and the plurality of first clamping jaws 41 are used to clamp the carrier cover. Each first clamping jaw 41 corresponds to a carrier cover, and the clamping component 4 is configured to rotate with the flip plate 12.

[0036] It can be understood that in this embodiment, the carrier is transported to the working position 10 through a conveying device (not shown in the figure). The conveying device can be a conveyor belt or a conveying roller, etc. The conveying device is a prior art and will not be elaborated here. The carrier can also be transported to the working position 10 by a manipulator or manually, which is not limited here.

[0037] Specifically, refer to Figures 2 to 4, in this embodiment, the driving assembly 2 includes a driving member 21, a transmission wheel 22 and a driving wheel 23. A positioning plate 13 is fixed on the fixing plate 11, and the driving member 21 is fixed on the positioning plate 13. The driving member 21 is arranged towards the first direction X. The transmission wheel 22 is drivingly connected to the output shaft of the driving member 21. One end of the driving wheel 23 is fixedly connected to the flipping plate 12, and the driving wheel 23 is drivingly connected to the transmission wheel 22. Avoidance grooves 14 are formed in the fixing plate 11 and the frame 1. One end of the driving wheel 23 away from the flipping plate 12 passes through the avoidance groove 14 and can rotate in the avoidance groove 14. A rotating shaft 24 is arranged on the fixing plate 11. The axis of the rotating shaft 24 extends along the first direction X. The flipping plate 12 is rotationally connected to the fixing plate 11 through the rotating shaft 24. The driving wheel 23 is arc-shaped and coaxially arranged with the rotating shaft 24.

[0038] It is not difficult to understand that in this embodiment, the driving member 21 is specifically a stepping motor, and it can also be a servo motor, etc. The transmission wheel 22 and the driving wheel 23 are both gears in this embodiment. An auxiliary gear 25 can be arranged on the transmission wheel 22. The auxiliary gear 25 is rotatably installed on the positioning plate 13. The auxiliary gear 25 meshes with the transmission wheel 22 and the driving wheel 23 respectively. The number of the auxiliary gears 25 can be one or more, which is not limited herein.

[0039] The driving member 21 drives the transmission wheel 22 to rotate. The transmission wheel 22 drives the auxiliary wheel to rotate. The auxiliary wheel drives the driving wheel 23 to rotate. The driving wheel 23 drives the flipping plate 12 to deflect around the axis of the rotating shaft 24, so as to realize the rotation of the rotating plate and the clamping assembly 4 on the rotating plate, which is convenient for clamping the vehicle cover and is easy to operate. In addition, in this application, by adopting the transmission wheel 22, the auxiliary wheel and the driving wheel 23 to drive the flipping plate 12 to rotate, compared with the existing technologies using synchronous wheels and synchronous belts or cylinders, this application has the advantages of durability and not being easily damaged, which helps to ensure the service life of the flipping and opening mechanism.

[0040] Furthermore, a limiting rod 3 is arranged on the fixing plate 11, and a limiting block 31 is arranged on the driving wheel 23. The limiting block 31 penetrates through the driving wheel 23 along the axial direction of the driving wheel 23. The limiting rod 3 has a limiting inclined surface 32 arranged towards the limiting block 31, and the limiting inclined surface 32 can contact with the limiting block 31. After the first clamping jaw 41 clamps the vehicle cover, the first clamping jaw 41 drives the vehicle cover to rotate to realize the opening action. The limiting inclined surface 32 on the limiting rod 3 can limit the flipping plate 12 from continuing to rotate towards the side close to the fixing plate 11 after the flipping plate 12 rotates to a state perpendicular to the fixing plate 11, so as to realize the limiting of the flipping plate 12. That is to say, there is an included angle α between the extending plane of the flipping plate 12 and the extending plane of the fixing plate 11, satisfying 0°≤α≤90°.

[0041] Refer to Figure 5The flip cover opening mechanism also includes a positioning assembly 7, which includes a positioning cylinder 71 and a positioning block 72. The positioning cylinder 71 is installed on the frame 1, and the positioning cylinder 71 is arranged toward the working position 10. The positioning block 72 is fixed on the piston rod of the positioning cylinder 71, and the positioning block 72 is used to position the carrier. Specifically, when the carrier moves to the working position 10, the positioning cylinder 71 pushes the positioning block 72 toward the side of the working position 10, and the positioning block 72 fixes the carrier at the working position 10, so as to avoid the position of the carrier from being offset during the cover opening process as much as possible, so as to ensure a good cover opening effect.

[0042] See also Figure 1 The flip cover opening mechanism also includes a moving assembly 6, which includes a moving cylinder 61 and a moving guide rail 62. The moving cylinder 61 is fixedly mounted on the fixed plate 11, and the moving cylinder 61 is arranged away from the working position 10. A fixed block 63 is installed on the frame 1, and the piston rod of the moving cylinder 61 is fixedly connected to the fixed block 63. The moving guide rail 62 is installed on the frame 1 along the second direction Y. Two moving guide rails 62 are provided and are arranged at intervals along the first direction X. A moving slider 64 is slidably installed on the moving guide rail 62. The fixed plate 11 is installed on the moving slider 64. The fixed plate 11 can move along the second direction Y with the moving slider 64 to approach or move away from the working position 10 under the action of the moving cylinder 61.

[0043] When the carrier moves to the working position 10, the piston rod of the moving cylinder 61 extends, and the moving cylinder 61 drives the fixed plate 11 to move toward the side close to the working position 10, so that after the flip plate 12 is flipped, the first clamp 41 can be located on the side of the carrier away from the fixed plate 11, so that the first clamp 41 can better clamp the carrier cover, and the problem of clamping failure caused by the first clamp 41 not being in place can be avoided as much as possible.

[0044] For further information, see Figure 5 A mounting groove 81 is provided on the side of the fixed plate 11 close to the working position 10, and a limit plate 8 is fixed on the frame 1, and the limit plate 8 is arranged in the limit groove 410. In the initial state, there is a gap between the fixed plate 11 and the limit plate 8. When the moving cylinder 61 drives the fixed plate 11 to move toward the side close to the working position 10, the limit plate 8 can contact the fixed plate 11, and the limit plate 8 limits the fixed plate 11 from continuing to move toward the working position 10, thereby limiting the movement of the fixed plate 11, preventing the fixed plate 11 from being displaced too much, and avoiding the fixed plate 11 from hitting the carrier on the working position 10 as much as possible.

[0045] See below Figures 4 to 7, the clamping assembly 4 further includes a pushing cylinder 42 and a plurality of first slide rails 43, and the first slide rails 43 are arranged at intervals along the first direction X. In this embodiment, there are specifically two first slide rails 43, and a first slider 44 is slidably mounted on each first slide rail 43. In the initial state of the flipping and opening mechanism, the first slider 44 can slide along the third direction Z. A first clamping jaw 41 is mounted on each first slider 44, and the first clamping jaw 41 is detachably connected to the first slider 44. An installation plate 40 is fixed on the first slider 44, and the installation plate 40 can move relative to the flipping plate 12 along the third direction Z with the first slider 44. The pushing cylinder 42 is fixed on the installation plate 40, and a connecting plate 15 is fixed on the flipping plate 12. The piston rod of the pushing cylinder 42 is fixedly connected to the connecting plate 15.

[0046] When the driving assembly 2 drives the flipping plate 12 to rotate to a state parallel to the fixing plate 11, the pushing cylinder 42 acts. The pushing cylinder 42 pushes the connecting block 47, causing itself, the installation plate 40, the first slider 44, and the first clamping jaw 41 to move toward the side close to the fixing plate 11, and the first clamping jaw 41 is clamped into the carrier cover to achieve clamping of the carrier cover.

[0047] In one embodiment, refer to Figure 1 , Figure 4 and Figure 5 , the clamping assembly 4 further includes a second slide rail 45 and a plurality of second clamping jaws 46. Preferably, the number of the second clamping jaws 46 is specifically two. The second slide rail 45 is installed on the flipping plate 12, and a plurality of connecting blocks 47 are installed on the second slide rail 45. Preferably, the number of the connecting blocks 47 is two. The connecting blocks 47 are slidably mounted on the second slide rail 45 along the first direction X, and the second clamping jaws 46 are installed on the connecting blocks 47. Two limiting grooves 410 are formed in the installation plate 40, and the limiting grooves 410 are inclined. The distance between the two limiting grooves 410 increases from the side far from the fixing plate 11 to the side close to the fixing plate 11. A limiting member 48 is arranged on each connecting block 47, and the limiting member 48 passes through the limiting groove 410. Two adjacent second clamping jaws 46 are configured to approach or separate from each other along the first direction X with the movement of the pushing cylinder 42.

[0048] Specifically, when the pushing cylinder 42 drives the installation plate 40 to move, by driving the limiting member 48 to move in the limiting groove 410, two adjacent connecting blocks 47 approach or separate from each other along the first direction X on the second slide rail 45, so as to realize the approach or separation between the two second clamping jaws 46. The two second clamping jaws 46 are also used to clamp the carrier cover. Thus, by providing two first clamping jaws 41 and two second clamping jaws 46, the two second clamping jaws 46 are respectively used to clamp the carrier covers of two carriers, and the two second clamping jaws 46 cooperate to clamp one carrier cover. Under the action of one pushing cylinder 42, the first clamping jaws 41 and the second clamping jaws 46 can simultaneously clamp the carrier covers of three carriers, thereby improving the opening efficiency.

[0049] Further, in some embodiments, the first clamping jaw 41 includes a connecting portion 413, a first clamping portion 411, and a second clamping portion 412. The connecting portion 413 is mounted on the first slider 44. The first clamping portion 411 and the second clamping portion 412 are provided at one end of the connecting portion 413 away from the first slider 44. Both the first clamping portion 411 and the second clamping portion 412 are oriented towards the working position 10. A clamping groove 414 is provided between the first clamping portion 411 and the second clamping portion 412, and the carrier cover is adapted to be snapped into the clamping groove 414. On the side of the first clamping portion 411 and the second clamping portion 412 close to the clamping groove 414, inclined surfaces 415 are provided, which can facilitate the carrier cover to be snapped into the clamping groove 414 and facilitate clamping of the carrier cover.

[0050] In this embodiment, the connection between the first clamping jaw 41 and the first slider 44 is detachable, which can be by bolt connection or other connection methods such as snap connection, and is not limited herein. Since the connection between the first clamping jaw 41 and the first slider 44 is detachable, a first clamping jaw 41 with a suitable size can be selected according to the sizes of the carrier and the carrier cover, so as to improve the adaptability of the flipping and opening mechanism. In addition, the connection between the second clamping jaw 46 and the connecting block 47 is detachable, and a second clamping jaw 46 with a suitable size can also be selected according to the sizes of the carrier and the carrier cover, further improving the adaptability of the flipping and opening mechanism.

[0051] The working process of the flipping and opening mechanism provided by this application is as follows: The carrier moves from the previous process to the working position 10. The moving cylinder 61 pushes the fixing plate 11 towards the side close to the working position 10, and the driving assembly 2 drives the flipping plate 12 to flip towards the side close to the working position 10. Then, under the action of the pushing cylinder 42, the first clamping jaw 41 and the second clamping jaw 46 simultaneously clamp a plurality of carrier covers. Subsequently, the driving assembly 2 drives the flipping plate 12 to move in the reverse direction, thereby driving the carrier cover to rotate 90°, realizing the opening operation.

[0052] As described above, only some embodiments of the embodiments of this application are provided, and there is no limitation in any form to this application. The protection scope of the embodiments of this application is not limited thereto.
