Description

Technical Field

[0001] The present application relates to the field of lithium battery production equipment, and specifically to a rotary transport device. Background Art

[0002] During the production process, it is often necessary to transport two workpieces from one station to another by a transport mechanism. In some cases, in addition to transporting the two workpieces at the first station to the second station, it is also necessary to implement the redirection of the two workpieces. For example, Figure 1 As shown, the two workpieces 100 are adjusted from a side-by-side state at the first station A to a co-linear state at the second station B.

[0003] The existing method is to first use a transport mechanism to transport the two workpieces from the first station to the second station, and then use a reversing mechanism located next to the second station to perform the reversing operation on the two workpieces. This processing method requires an additional reversing mechanism to perform the reversing operation on the workpieces, and the transport mechanism and reversing mechanism can only operate sequentially, which not only increases equipment costs but also reduces production efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a rotary transport device, which adopts the following technical solutions:

[0005] A rotary transport device includes a base, a driving portion, a carrying plate, a steering assembly, a first clamping assembly, and a second clamping assembly, wherein:

[0006] The driving part is arranged on the base;

[0007] The carrier plate is connected to a movable component of a driving portion, and the driving portion is configured to drive the carrier plate to rotate relative to the base;

[0008] The steering assembly is at least partially disposed on the bearing plate, and the first clamping assembly and the second clamping assembly are respectively connected to one of the driving ends of the steering assembly;

[0009] The first clamping assembly and the clamping assembly are each configured to clamp a workpiece;

[0010] The steering assembly is configured to drive the first clamping assembly and the second clamping assembly to rotate synchronously relative to the carrier plate, so as to implement synchronous steering of the two clamped workpieces.

[0011] The rotary transport device provided by the present application drives the carrier plate to rotate relative to the base through a driving unit, thereby driving the first clamping assembly and the clamping assembly to synchronously transport the clamped workpiece from the first station to the second station. During the transport process, the steering assembly drives the first clamping assembly and the second clamping assembly to rotate synchronously around their own central axis, thereby completing the synchronous steering of the two workpieces. It can be seen that the rotary transport device provided by the present application realizes the steering operation of the two workpieces during the transport process, thereby improving the transport efficiency and reducing the equipment cost.

[0012] In some embodiments, the steering assembly includes a driving wheel, a synchronous belt, a driven wheel, a first rotating arm, a second rotating arm, a first connecting rod, a second connecting rod and a hinge shaft, wherein: the driving wheel is fixedly connected to the base, and N meshing teeth are provided on the outer circumference of the driving wheel; the driven wheel is rotatably mounted on the supporting plate, and 2N meshing teeth are provided on the outer circumference of the driven wheel; the synchronous belt is wound around the driving wheel and the driven wheel, and the synchronous belt is meshed with the driving wheel and the driven wheel respectively; the middle part of the first rotating arm is connected to the mounting shaft of the driven wheel, the first clamping assembly is rotatably connected to the first end of the first rotating arm, and the second clamping assembly is rotatably connected to the second end of the first rotating arm; the first end of the first connecting rod is fixedly connected to the first clamping assembly, and the first connecting rod is fixedly connected to the first clamping assembly. The second end of the hinge is hinged to the first end of the second rotating arm, and the first end of the second connecting rod is fixedly connected to the second clamping assembly, and the second end of the second connecting rod is hinged to the second end of the second rotating arm, the first connecting rod is parallel to the second connecting rod, and the second rotating arm is parallel to the first rotating arm; the first end of the hinge shaft is rotatably connected to the carrying plate, and the second end of the hinge shaft is fixedly connected to the middle of the second rotating arm; when the driving part drives the carrying plate to rotate relative to the base, the synchronous belt drives the driven wheel to rotate relative to the carrying plate, thereby driving the first rotating arm to rotate horizontally relative to the carrying plate, and the hinge shaft drives the second rotating arm to rotate, and when the second rotating arm rotates, the first clamping assembly and the second clamping assembly are driven to rotate relative to the first rotating arm via the first connecting rod and the second connecting rod.

[0013] When the driving part drives the supporting plate to rotate relative to the base and adjusts the first clamping assembly and the second clamping assembly from the first station to the second station, the synchronous belt drives the driven wheel to rotate relative to the supporting plate, thereby driving the first rotating arm to rotate horizontally relative to the supporting plate. At the same time, the hinge shaft drives the second rotating arm to rotate. When the second rotating arm rotates, it drives the first clamping assembly and the second clamping assembly to rotate relative to the first rotating arm through the first connecting rod and the second connecting rod respectively.

[0014] As can be seen, when the driving unit drives the carrier plate to rotate, it can drive the first clamping assembly and the second clamping assembly to transport the two clamped workpieces from the first station to the second station, and can also drive the steering assembly to rotate the first clamping assembly and the second clamping assembly, thereby achieving the steering of the two clamped workpieces. In other words, by providing the steering assembly, the present application only needs to provide a single driving unit to complete the transportation and steering of two workpieces, thereby reducing equipment costs.

[0015] In some embodiments, the first clamping assembly and the second clamping assembly have the same structure, and the first clamping assembly includes a mounting base, a first driving member, a first clamping plate and a second clamping plate, wherein: the mounting base is rotatably connected to the first end of the first rotating arm, and the first end of the first connecting rod is fixedly connected to the mounting base; the first clamping plate and the second clamping plate are slidably connected to the mounting base, and are respectively transmission-connected to the first driving member, and the first driving member is configured to drive the first clamping plate and the second clamping plate to slide closer to the middle or slide apart to both sides to clamp or release the workpiece.

[0016] By setting the first clamping assembly and the second clamping assembly, the first clamping assembly and the second clamping assembly can both quickly clamp and release the workpiece, and the first clamping assembly and the second clamping assembly can both rotate relative to the first rotating arm, thereby turning the clamped workpiece.

[0017] In some embodiments, anti-slip structures are provided on the opposite clamping surfaces of the first clamping plate and the second clamping plate.

[0018] Anti-slip structures are provided on the opposite clamping surfaces of the first clamping plate and the second clamping plate to prevent the clamped workpiece from slipping.

[0019] In some embodiments, the driving portion includes a second driving member and a turntable, wherein: the turntable is rotatably connected to the base, the supporting plate is fixedly connected to the end face of the turntable, the second driving member is installed on the base and is transmission-connected to the turntable; the second driving member is configured to drive the turntable to rotate, so as to drive the supporting plate to rotate relative to the base.

[0020] By arranging the driving part, the driving part can drive the carrying plate to rotate relative to the base, and the connection strength between the carrying plate and the driving part is ensured.

[0021] In some embodiments, a through hole is provided on the turntable and passes through the turntable, and the driving wheel is fixedly mounted on the base via a connecting shaft passing through the through hole.

[0022] By arranging a through hole penetrating the turntable on the turntable, the connecting shaft of the driving wheel is avoided, ensuring that the driving wheel can be fixedly installed on the base.

[0023] In some embodiments, the steering assembly further includes a tensioning wheel, which is adjustably disposed on the carrier plate and configured to press the synchronous belt from the outside.

[0024] By providing a tensioning wheel, the synchronous belt is tensioned to prevent the synchronous belt from slipping and affecting the driving stability of the first rotating arm.

[0025] In some embodiments, the steering assembly further includes a slider, a bolt mounting seat and a bolt, wherein: the slider is slidably connected to the supporting plate, and the tensioning wheel is mounted on the slider; the bolt mounting seat is mounted on the supporting plate and is located on the side of the slider, the bolt is threaded on the bolt mounting seat, and the end of the bolt rests on the slider.

[0026] This allows for flexible adjustment of the tension of the synchronous belt, ensuring that the belt can drive the driven pulley to rotate smoothly. Specifically, if the belt is too loose, the bolt is rotated inward to increase the pressure of the tensioner on the belt. If the belt is too tight, the bolt is rotated outward to reduce the pressure of the tensioner on the belt.

[0027] In some embodiments, the driving portion is configured to drive the carrier plate to rotate 180° relative to the base, and the steering assembly is configured to drive the first clamping assembly and the second clamping assembly to synchronously rotate 90° around their own central axes.

[0028] The two workpieces placed side by side at the first station are turned and adjusted to a collinear state while being transported to the second station.

[0029] In some embodiments, the steering assembly includes a third drive member and a fourth drive member arranged side by side on the supporting plate, the first clamping assembly is connected to the drive end of the third drive member, and the second clamping assembly is connected to the drive end of the fourth drive member; the third drive member and the fourth drive member are configured to synchronously drive the first clamping assembly and the second clamping assembly to rotate around their own central axes.

[0030] When the driving part drives the supporting plate to rotate relative to the base and adjusts the first clamping assembly and the second clamping assembly from the first station to the second station, the third driving member and the fourth driving member synchronously drive the first clamping assembly and the second clamping assembly to rotate, thereby realizing the transportation and steering of the two workpieces.

[0047] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] like Figures 2 to 8 As shown, the rotary transport device in the embodiment of the present application includes a base 1, a driving part 2, a carrying plate 3, a steering assembly 4, a first clamping assembly 5 and a second clamping assembly 6, wherein:

[0049] The driving unit 2 is provided on the base 1 .

[0050] The supporting plate 3 is connected to a movable component of the driving portion 2 , and the driving portion 2 is configured to drive the supporting plate 3 to rotate relative to the base 1 .

[0051] The steering assembly 4 is at least partially disposed on the carrying plate 3 , and the first clamping assembly 5 and the second clamping assembly 6 are respectively connected to one of the driving ends of the steering assembly 4 .

[0052] The first clamping assembly 4 and the clamping assembly 5 are each configured to clamp a workpiece.

[0053] The steering assembly 4 is configured to drive the first clamping assembly 5 and the second clamping assembly 6 to rotate synchronously around their own central axis, so as to implement synchronous steering of the two clamped workpieces.

[0054] The rotary transport device of the embodiment of the present application drives the supporting plate 3 to rotate relative to the base 1 through the driving part 2, thereby driving the first clamping component 5 and the clamping component 6 to synchronously transport the clamped workpiece from the first station to the second station. During the transportation process, the steering component 4 drives the first clamping component 5 and the clamping component 6 to rotate synchronously around their own central axis, thereby completing the synchronous steering of the two workpieces.

[0055] It can be seen that the rotary transport device of the embodiment of the present application can realize the steering operation of two workpieces during the transport process, thereby improving the transport efficiency and reducing the equipment cost.

[0056] Optionally, the steering assembly 4 includes a driving wheel 41, a synchronous belt 42, a driven wheel 43, a first rotating arm 44, a second rotating arm 45, a first connecting rod 46, a second connecting rod 47 and a hinge shaft 48, wherein:

[0057] A driving pulley 41 is fixedly connected to the base 1 and has N meshing teeth on its outer circumference. A driven pulley 43 is rotatably mounted on the carrier plate 3 and has 2N meshing teeth on its outer circumference. A synchronous belt 42 is wound around the driving pulley 41 and the driven pulley 43, meshing with each of the driving pulleys 41 and the driven pulley 43.

[0058] The middle portion of the first rotating arm 44 is connected to the mounting shaft 431 of the driven wheel 43 . The first clamping assembly 5 is rotatably connected to the first end of the first rotating arm 44 . The second clamping assembly 6 is rotatably connected to the second end of the first rotating arm 44 .

[0059] The first end of the first connecting rod 46 is fixedly connected to the first clamping assembly 5, the second end of the first connecting rod 46 is hinged to the first end of the second rotating arm 45, the first end of the second connecting rod 47 is fixedly connected to the second clamping assembly 6, the second end of the second connecting rod 47 is hinged to the second end of the second rotating arm 45, the first connecting rod 46 is parallel to the second connecting rod 47, and the second rotating arm 45 is parallel to the first rotating arm 44.

[0060] A first end of the hinge shaft 48 is rotatably connected to the supporting plate 3 , and a second end of the hinge shaft 48 is fixedly connected to the middle portion of the second rotating arm 45 .

[0061] When the driving unit 2 drives the supporting plate 3 to rotate relative to the base 1, the synchronous belt 42 drives the driven wheel 43 to rotate relative to the supporting plate 3, thereby driving the first rotating arm 44 to rotate horizontally relative to the supporting plate 3, and the hinge shaft 48 drives the second rotating arm 45 to rotate. When the second rotating arm 45 rotates, it drives the first clamping assembly 5 and the second clamping assembly 6 to rotate relative to the first rotating arm 44 through the first connecting rod 46 and the second connecting rod 47 respectively.

[0062] The following will be based on the background technology part Figure 1 The working process of the rotary transport device in the embodiment of the present application is described exemplarily by taking the transport scenario in FIG. That is, two workpieces 100 need to be transported from a first workstation A to a second workstation B, and the two workpieces 100 need to be adjusted from a side-by-side state to a collinear state.

[0063] like Figure 3 As shown, first, the first clamping assembly 5 and the clamping assembly 6 are adjusted to a side-by-side state, and the first clamping assembly 5 and the second clamping assembly 6 are controlled to respectively clamp a workpiece 100 from the first workstation A.

[0064] Subsequently, the driving unit 2 drives the carrying plate 3 to rotate 180° relative to the base 1 , so as to rotate and transport the two workpieces 100 to the second workstation B.

[0065] like Figure 4 As shown, since the driving wheel 41 is fixedly connected to the base 1, the driven wheel 43 is rotatably installed on the supporting plate 3, and the number of meshing teeth of the driven wheel 43 is twice that of the driving wheel 41, during the rotation of the supporting plate 3 relative to the base 1, the synchronous belt 42 rotates relative to the driving wheel 41, thereby driving the driven wheel 43 to rotate 90° relative to the supporting plate 3, and the first rotating arm 44 rotates horizontally 90° relative to the supporting plate 3 under the drive of the driven wheel 43.

[0066] At the same time, if Figures 4 to 8As shown, since the first end (such as the upper end) of the hinge shaft 48 is rotatably connected to the supporting plate 3, and the second end (such as the lower end) of the hinge shaft 48 is fixedly connected to the second rotating arm 45, during the process of the first rotating arm 44 rotating horizontally 90° relative to the supporting plate 3, the hinge shaft 48 pushes the second rotating arm 45 to rotate, and when the second rotating arm 45 rotates, it drives the first clamping assembly 5 and the second clamping assembly 6 to rotate relative to the first rotating arm 44 through the first connecting rod 46 and the second connecting rod 47, and finally makes the first clamping assembly 5 and the second clamping assembly 6 rotate 90° around their respective center axes, so that the first clamping assembly 5 and the second clamping assembly 6 are switched from the initial side-by-side state to the collinear state, that is, the two workpieces 100 clamped by the first clamping assembly 5 and the second clamping assembly 6 are also adjusted and switched to the collinear state.

[0067] Finally, if Figure 4 As shown, the first clamping assembly 5 and the second clamping assembly 6 are controlled to release the two workpieces 100 to the second workstation B.

[0068] It can be seen that the driving part 2 drives the carrying plate 3 to rotate, driving the first clamping component 5 and the second clamping component 6 to transport the two clamped workpieces 100 from the first station A to the second station B, and can also drive the steering component 4 to rotationally drive the first clamping component 5 and the second clamping component 6, thereby realizing the steering of the two clamped workpieces 100.

[0069] That is to say, by performing the above-mentioned configuration on the steering assembly 4 , the present application only needs to configure one driving unit 2 to complete the transportation and steering of two workpieces 100 , thereby reducing equipment costs.

[0070] Of course, in other embodiments, a steering assembly independent of the drive unit 2 may be provided to steer the first and second clamping assemblies 5, 6. For example, the rotation assembly may include a third and fourth driving members disposed side by side on the carrier plate 3, with the first clamping assembly 5 connected to the driving end of the third driving member 6, and the second clamping assembly 6 connected to the driving end of the fourth driving member. The third and fourth driving members are configured to synchronously drive the first and second clamping assemblies 5, 6 to rotate about their respective central axes, thereby steering the first and second clamping assemblies 5, 6.

[0071] Optionally, the first clamping assembly 5 and the second clamping assembly 6 have the same structure. Figures 3 to 8As shown, taking the first clamping assembly 5 as an example, it includes a mounting base 51, a first driving member 52, a first clamping plate 53, and a second clamping plate 54. The mounting base 51 is rotatably connected to the first end of the first rotating arm 44, and the first end of the first connecting rod 46 is fixedly connected to the mounting base 51. The first clamping plate 53 and the second clamping plate 54 are slidably connected to the mounting base 51 and are respectively in transmission connection with the first driving member 52. The first driving member 52 is configured to drive the first clamping plate 53 and the second clamping plate 54 to slide toward the center or slide toward the sides to separate to clamp or release the workpiece.

[0072] By setting the first clamping assembly 5 and the second clamping assembly 6, the first clamping assembly 5 and the second clamping assembly 6 can both quickly clamp and release the workpiece, and the first clamping assembly 5 and the second clamping assembly 6 can rotate relative to the first rotating arm 44 under the drive of the first connecting rod 46 and the second connecting rod 47, thereby implementing the steering of the clamped workpiece.

[0073] The first driving member 52 can be, for example, a double-headed cylinder, and the first clamping plate 53 and the second clamping plate 54 are respectively connected to one driving end of the double-headed cylinder. When the double-headed cylinder drives the first clamping plate 53 and the second clamping plate 54 to slide toward the middle, the tooling is clamped, and when the double-headed cylinder drives the first clamping plate 53 and the second clamping plate 54 to slide apart to both sides, the tooling is released.

[0074] In order to prevent the clamped workpiece from slipping, optionally, anti-slip structures are provided on the opposite clamping surfaces of the first clamping plate 53 and the second clamping plate 54. The anti-slip structures may be, for example, a plurality of anti-slip grooves arranged side by side.

[0075] like Figures 2 to 4 As shown, the driving unit 2 optionally includes a second driving member 21 and a turntable 22, wherein the turntable 22 is rotatably connected to the base 1, the supporting plate 3 is fixedly connected to the end surface of the turntable 22, and the second driving member 21 is mounted on the base 1 and is in driving connection with the turntable 22. The second driving member 21 is configured to drive the turntable 22 to rotate, thereby driving the supporting plate 3 to rotate relative to the base.

[0076] To avoid the driving wheel 41 and ensure that it is securely mounted to the base 1, the turntable 22 is optionally provided with a through-hole extending therethrough, and the driving wheel 41 is securely mounted to the base 1 via a connecting shaft passing through the through-hole. In this manner, when the second driving member 21 drives the turntable 22 to rotate, it does not affect the driving wheel 41, and the driving wheel 41 does not rotate with the turntable 22.

[0077] like Figure 5As shown, the steering assembly 4 optionally further includes a tensioning wheel 49, which is adjustably positioned on the carrier plate 3 and configured to press the timing belt 42 from the outside. The provision of the tensioning wheel 49 allows the timing belt 42 to be tensioned, preventing the timing belt 42 from slipping and affecting the driving stability of the first rotating arm 44.

[0078] Optionally, the steering assembly 4 further includes a slider 410, a bolt mounting seat 411, and a bolt 412, wherein the slider 410 is slidably connected to the carrier plate 3, and the tensioning pulley 49 is mounted on the slider 410. The bolt mounting seat 411 is mounted on the carrier plate 3 and is located on the side of the slider 410. The bolt 412 is screwed onto the bolt mounting seat 411, and the end of the bolt 412 abuts against the slider 410. When the synchronous belt 42 is too loose, the bolt 412 is rotated inward, pushing the slider 410 toward the synchronous belt 42, thereby increasing the pressure of the tensioning pulley 49 on the synchronous belt 42. When the synchronous belt 42 is too tight, the bolt 412 is rotated outward, thereby reducing the pressure of the tensioning pulley 49 on the synchronous belt 42. Ultimately, the synchronous belt 42 is ensured to be properly tight and connected to the driving pulley 41 and the driven pulley 43.

[0079] As described in the previous embodiment, the drive unit 2 can optionally be configured to drive the carrier plate 3 to rotate 180° relative to the base, and the steering assembly 4 can be configured to drive the first clamping assembly 5 and the clamping assembly 6 to rotate 90° about their respective central axes. In this manner, it is possible to transport two workpieces 100 from the first workstation A to the second workstation B, and to adjust the two workpieces 100 from a side-by-side position to a collinear position during the transport process.

[0080] Of course, in other embodiments, according to the relative position of the second workstation and the first workstation, and the specific requirements for steering, the driving unit 2 can also be configured to drive the supporting plate 3 to rotate relative to the base at an angle other than 180°, and the steering assembly 4 can also be configured to drive the first clamping assembly 5 and the clamping assembly 6 to rotate synchronously relative to the base at an angle other than 90°.

[0081] The above description of the present application is sufficiently detailed and has certain particularities. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and that all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the above description in the embodiments. Furthermore, the embodiments mentioned in the present application are not limited to being implemented individually, and some embodiments can also be implemented in combination.
