Description

Technical Field

[0001] This invention belongs to the field of automation devices and equipment technology, specifically relating to a clamping and flipping device and a transfer device. Background Technology

[0002] Those skilled in the art will know that the product processing may involve several operational steps, often requiring the product to be placed on the assembly line in different postures (e.g., upright, reversed, or sideways) so that machines or humans can perform processing or inspection operations on the corresponding parts.

[0003] In earlier years, the handling and flipping of products on or between assembly lines were all done manually. For example, in the production of air conditioner indoor units, it was necessary to manually flip the air conditioner indoor units or move them across the assembly line. This method was labor-intensive, inefficient, and could not be standardized, which could easily lead to human error.

[0004] In recent years, automated robotic arms have become an important component of the high-end equipment manufacturing industry, with increasingly widespread applications. Consequently, the industry has developed various types of gripping and flipping devices that can simultaneously grip and flip products.

[0005] Existing clamping and flipping devices generally include a support frame, a left clamping and flipping part, a right clamping and flipping part, and a clamping drive assembly. The left and right clamping and flipping parts are movably arranged on the support frame facing each other or in opposite directions. The clamping drive assembly is arranged on the support frame and drives the left and right clamping and flipping parts to move relative to each other. The left and right clamping and flipping parts each include a clamping plate and a clamping and flipping component, and the two clamping and flipping components are respectively arranged on opposite sides of the two clamping plates. One of the left and right clamping and flipping parts is provided with a flipping drive assembly, which drives at least one clamping and flipping component to rotate.

[0006] Existing clamping and flipping devices are mainly classified into the following categories according to their different clamping drive methods: (1) The left clamping and flipping part and the right clamping and flipping part are driven by a cylinder to perform their respective clamping strokes; (2) The left clamping and flipping part and the right clamping and flipping part, one of which does not perform clamping activities, and the other is driven by a cylinder to perform relative clamping activities.

[0007] As can be seen from the above, in the existing clamping and flipping devices, the maximum clamping stroke of each clamping and flipping part is the stroke of a cylinder power arm. This makes the control of the opening stroke and clamping stroke of the clamping and flipping part not flexible enough, and the adjustment of the clamping area that can be covered is not flexible enough. It cannot quickly adapt to objects of different widths and cannot meet a wider range of application needs.

[0008] In addition, existing clamping and flipping devices can only perform clamping and flipping operations in place and cannot transfer products across production lines; while in the existing method, products are transferred between two production lines by hand, which is not only prone to misoperation, but also has a high risk. Summary of the Invention

[0009] The first aspect of this invention aims to provide a clamping and flipping device, with the purpose of improving the flexibility of use of the clamping and flipping device. The first aspect of this invention is achieved by the following technical solution:

[0010] A clamping and flipping device includes a support frame, a first clamping and flipping part, a second clamping and flipping part, and a clamping drive assembly. The first clamping and flipping part is fixedly mounted on the support frame, and the second clamping and flipping part is movably mounted on the support frame relative to the first clamping and flipping part along the X-axis. The clamping drive assembly includes a first cylinder, a second cylinder, and a connecting member. The ends of the power arms of the first cylinder and the second cylinder are arranged facing each other and fixedly connected by the connecting member. The cylinder body of the first cylinder is fixedly mounted on the support frame and located on the same side as the first clamping and flipping part, and the cylinder body of the second cylinder is movably mounted on the support frame along the X-axis and fixedly connected to the second clamping and flipping part.

[0011] As a specific technical solution, a slide rail is provided on the support frame along the X-axis, and the cylinder body of the second cylinder is mounted on the slide rail via a slider.

[0012] As a specific technical solution, the first clamping and flipping part includes a first clamping plate and a first clamping and flipping member, and the second clamping and flipping part includes a second clamping plate and a second clamping and flipping member; the first clamping and flipping member and the second clamping and flipping member are rotatably disposed on opposite sides of the first clamping plate and the second clamping plate respectively; the first clamping and flipping part or the second clamping and flipping part further includes a flipping drive assembly disposed on the first clamping plate or the second clamping plate, and the flipping drive assembly drives the first clamping and flipping member or the second clamping and flipping member to rotate.

[0013] As a specific technical solution, the flipping drive component is a rotary cylinder or a stepper motor, and is located on the opposite side of the first clamping plate or the second clamping plate.

[0014] As a specific technical solution, it also includes a flipping linkage mechanism, in which the first flipping drive component drives the second clamping flipping component to rotate synchronously with the first clamping flipping component through the flipping linkage mechanism.

[0015] As a specific technical solution, the flipping linkage mechanism includes a first set of synchronous wheels, a second set of synchronous wheels, and a drive shaft; the drive shaft is arranged along the X-axis, with a first end of the drive shaft disposed on the first clamping plate and a second end disposed on the second clamping plate; the flipping drive assembly and the second set of synchronous wheels are disposed on the second clamping plate, the flipping drive assembly directly drives the second clamping flipping component to rotate, and the second set of synchronous wheels respectively drive and cooperate with the second end of the flipping drive assembly and the drive shaft; the first set of synchronous wheels is disposed on the first clamping plate and respectively drive and cooperate with the first end of the first clamping flipping component and the drive shaft.

[0016] In the clamping and flipping device provided by the above solution, the clamping drive assembly adopts a structure with two cylinders and their drive ends connected. Thus, the second clamping and flipping part, as the movable side, has a maximum clamping stroke equal to the stroke of the two cylinder power arms, and this stroke can be adjusted in stages. For example, when the current batch of objects to be clamped is narrow, the power arm of the first cylinder is controlled to remain retracted, while the power arm of the second cylinder is controlled to extend and retract in real time during each clamping operation to complete the clamping operation; or, the power arm of the second cylinder is controlled to remain retracted, while the power arm of the first cylinder is controlled to extend and retract in real time during each clamping operation to complete the clamping operation; as another example, when the current batch of objects to be clamped is wide, the power arm of the first cylinder is controlled to remain extended, while the power arm of the second cylinder is controlled to extend and retract in real time during each clamping operation to complete the clamping operation; as yet another example, when the current batch of objects to be clamped has varying widths, both the power arms of the first and second cylinders are controlled to extend and retract in real time to complete an adaptive clamping operation. As can be seen, the clamping and flipping device provided in this solution offers more flexible control over the opening and clamping strokes of the clamping and flipping part, and the adjustment of the clamping area that can be covered is also more flexible, enabling it to quickly adapt to objects of different widths and meet a wider range of application needs. Furthermore, the cylinder body of the second cylinder, as the component that drives the movement of the second clamping and flipping part, can provide a fixed connection point itself, eliminating the need for additional mechanisms such as connecting blocks for connecting the second clamping and flipping part, as is required in existing technologies where the end of the cylinder power arm is a moving part.

[0017] A second aspect of the present invention aims to provide another clamping and flipping device, also intended to improve the flexibility of use of the clamping and flipping device. The second aspect of the present invention is achieved by the following technical solution:

[0018] A clamping and flipping device includes a support frame, a first clamping and flipping part, a second clamping and flipping part, and a clamping drive assembly. The first and second clamping and flipping parts are movably mounted on the support frame along the X-axis. The clamping drive assembly includes a first cylinder, a second cylinder, and a connecting member. The ends of the power arms of the first and second cylinders are arranged facing each other and fixedly connected by the connecting member. The cylinder bodies of the first and second cylinders are movably mounted on the support frame along the X-axis and fixedly connected to the first and second clamping and flipping parts, respectively. A locking mechanism is provided on the support frame, and the cylinder bodies of the first and second cylinders and the connecting member are selectively locked to the support frame by the locking mechanism.

[0019] As a specific technical solution, a slide rail is provided on the support frame along the X-axis, and the cylinder bodies of the first cylinder and the second cylinder are respectively mounted on the slide rail via sliders.

[0020] As a specific technical solution, the locking mechanism is fixedly installed at both ends and in the middle of the support frame. Under control, the three locking mechanisms can selectively lock the cylinder body of the first cylinder, the cylinder body of the second cylinder, or the connecting piece onto the support frame.

[0021] In the clamping and flipping device provided by the above solution, the clamping drive assembly adopts a structure with two cylinders and their drive ends connected together. Simultaneously, the cylinder bodies of both cylinders and the two clamping and flipping parts connected to them can move along the X-axis. This allows for selection of one of the cylinder bodies of the first cylinder, the second cylinder, or the connecting parts as a base point for fixing, while the other parts serve as movable sides, making the use more flexible. For example, when the cylinder body of the first cylinder is selected as the fixed base point and fixed to the support frame using a locking mechanism, the cylinder body of the second cylinder and the second clamping and flipping part... The maximum clamping stroke is the stroke of two cylinder power arms, and it can be adjusted in increments; alternatively, when the cylinder body of the second cylinder is selected as the fixed base point and fixed to the support frame using a locking mechanism, the maximum clamping stroke of the cylinder body of the first cylinder and the first clamping tilting part is the stroke of two cylinder power arms, and it can be adjusted in increments; for another example, when the connecting piece is selected as the fixed base point and fixed to the support frame using a locking mechanism, the cylinder body of the first cylinder and the first clamping tilting part, and the cylinder body of the second cylinder and the second clamping tilting part can each perform the clamping operation with the stroke of one cylinder power arm. Similarly, by using the cylinder body as the component that drives the corresponding clamping tilting part, the cylinder body itself can provide a fixed connection position, eliminating the need for additional mechanisms such as connecting blocks for connecting the second clamping tilting part, as is the case in the prior art where the end of the cylinder power arm is a moving component.

[0022] A third aspect of the present invention is to provide a transfer device, which aims to improve the functionality of the transfer device. This third aspect of the present invention is achieved by the following technical solution:

[0023] A transfer device, comprising:

[0024] guide;

[0025] The movable frame is movably mounted on the guide rail;

[0026] The clamping and flipping device described above is mounted on the moving frame.

[0027] As a specific technical solution, the transfer device also includes a linear servo module that drives the moving frame to move along the guide rail.

[0028] As a specific technical solution, the guide rail includes a first guide rail and a second guide rail arranged in parallel, the movable frame includes a first support leg, a second support leg and an assembly plate, the first support leg and the second support leg are respectively movably disposed on the first guide rail and the second guide rail, and the two ends of the assembly plate are respectively disposed on the first support leg and the second support leg; the clamping and flipping device is disposed on the assembly plate.

[0029] As a specific technical solution, the two ends of the assembly plate are respectively mounted on the first support and the second support via lifting and adjusting mechanisms.

[0030] As a specific technical solution, the guide rail is arranged in the left-right direction, the assembly plate is arranged in the front-back direction, and the first clamping and flipping part and the second clamping and flipping part are located on the lower side of the assembly plate.

[0031] The transfer equipment provided by the above technical solution can achieve the functions of clamping, flipping, and transferring items across production lines when the guide rail spans at least two production lines. Compared with current transfer equipment with only a handling function, this solution can also automatically flip the clamped items while transferring, greatly saving manpower and improving production efficiency. In addition, by setting up a lifting and adjusting mechanism, the assembly plate and the clamping and flipping device set on it can be raised and lowered, thereby avoiding some interference during the transfer process and making the transfer operation easier to implement.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0041] Example 1

[0042] Combination Figure 1 As shown, Embodiment 1 of the present invention provides a clamping and flipping device 100, including a first clamping and flipping part 10, a second clamping and flipping part 20, a support frame 30, and a clamping drive assembly 40. The first clamping and flipping part 10 and the second clamping and flipping part 20 refer to components that clamp, release, and flip objects (such as indoor air conditioners) to achieve different orientations of the clamped objects, such as front-facing, back-facing, and side-facing.

[0043] In this embodiment, the first clamping and flipping part 10 is fixedly disposed on the support frame 30, and the second clamping and flipping part 20 is movably disposed on the support frame 30 relative to the first clamping and flipping part 10 along the X-axis. The clamping drive assembly 40 drives the second clamping and flipping part 20 to move relative to the first clamping and flipping part 10 along the X-axis.

[0044] The clamping drive assembly 40 includes a first cylinder 41, a second cylinder 42, and a connecting member 43. The ends of the power arm 412 of the first cylinder 41 and the power arm 422 of the second cylinder 42 are arranged facing each other and are fixedly connected by the connecting member 43, which is equivalent to coaxially connecting the power arms 412 of the first cylinder 41 and the power arms 422 of the second cylinder 42. The cylinder body 411 of the first cylinder 41 is fixedly mounted on the support frame 30 and located on the same side as the first clamping flipping part 10. The cylinder body 421 of the second cylinder 42 is movably mounted on the support frame 30 along the X-axis and is fixedly connected to the second clamping flipping part 20.

[0045] In this embodiment, the first clamping and flipping part 10 is fixedly disposed below one end of the support frame 30 or fixedly connected to the cylinder body 411 of the first cylinder 41; a slide rail 31 is provided on the support frame 30 along the X-axis, and the cylinder body 421 of the second cylinder 42 is disposed on the slide rail 31 by a slider 32; the second clamping and flipping part 20 is fixedly connected to the lower part of the cylinder body 421 of the second cylinder 42, is disposed opposite to the first clamping and flipping part 10, and can move towards or in the same direction relative to the first clamping and flipping part 10.

[0046] See also Figure 1 The first clamping and flipping part 10 includes a first clamping plate 11 and a first clamping and flipping member 12, and the second clamping and flipping part 20 includes a second clamping plate 21 and a second clamping and flipping member 22. The first clamping and flipping member 12 and the second clamping and flipping member 22 are rotatably disposed on opposite sides of the first clamping plate 11 and the second clamping plate 12, respectively. The first clamping and flipping part 10 also includes a flipping drive assembly disposed on the first clamping plate 11, which drives the first clamping and flipping member 12 to rotate; or, the second clamping and flipping part 20 also includes a flipping drive assembly 23 disposed on the second clamping plate 21, which drives the second clamping and flipping member 22 to rotate. In general, a flipping drive assembly is disposed on one side of the clamping and flipping part to drive the clamping and flipping member on that side to rotate, and the clamping and flipping member on the other side rotates synchronously.

[0047] Of course, as an alternative or more optimized implementation, the clamping and flipping device 100 may also include a flipping linkage mechanism (not shown in the figure), through which the flipping drive assembly drives the clamping and flipping member on the other side to rotate synchronously with the clamping and flipping member on that side.

[0048] Specifically, the flipping linkage mechanism includes a first set of synchronous pulleys, a second set of synchronous pulleys, and a drive shaft. The drive shaft is arranged along the X-axis, with its first end mounted on the first clamping plate 11 and its second end mounted on the second clamping plate 21. The flipping drive assembly and the second set of synchronous pulleys are mounted on the second clamping plate 21. The flipping drive assembly directly drives the second clamping flipping member 22 to rotate, and the second set of synchronous pulleys engages with the flipping drive assembly and the second end of the drive shaft, respectively. The first set of synchronous pulleys is mounted on the first clamping plate 11 and engages with the first clamping flipping member 12 and the first end of the drive shaft, respectively. In this way, the driving force of the flipping drive assembly mounted on the second clamping plate 21 can be transmitted to the first clamping flipping member 12 on the first clamping plate 11, causing the first clamping flipping member 12 and the second clamping flipping member 22 to rotate synchronously and actively.

[0049] Alternatively, as an alternative implementation, the flipping linkage mechanism includes a first set of synchronous pulleys, a second set of synchronous pulleys, and a drive shaft. The drive shaft is arranged along the X-axis, with its first end mounted on the first clamping plate 11 and its second end mounted on the second clamping plate 21. The flipping drive assembly and the first set of synchronous pulleys are mounted on the first clamping plate 11. The flipping drive assembly directly drives the first clamping flipping member 12 to rotate, and the first set of synchronous pulleys engages with the first end of the flipping drive assembly and the drive shaft, respectively. The second set of synchronous pulleys is mounted on the second clamping plate 21 and engages with the second clamping flipping member 22 and the second end of the drive shaft, respectively. In this way, the driving force of the flipping drive assembly mounted on the first clamping plate 11 can be transmitted to the second clamping flipping member 22 mounted on the second clamping plate 21, causing the first clamping flipping member 12 and the second clamping flipping member 22 to rotate synchronously and actively.

[0050] In this embodiment, the flipping drive component is a rotary cylinder, disposed on opposite sides of the first clamping plate 11 or the second clamping plate 21. Furthermore, it is understood that the rotary cylinder can be replaced by a stepper motor.

[0051] In the clamping and flipping device provided in the first embodiment above, the clamping drive assembly 40 adopts a structure with two cylinders and the driving ends of the two cylinders connected together; thus, the second clamping and flipping part 20, which is the movable side, has a maximum clamping stroke of the two cylinder power arms, and can be adjusted in stages, which will be described by example below.

[0052] For example, when the current batch of objects to be clamped is narrow, the power arm 412 of the first cylinder 41 is kept retracted for a long time, and the power arm 422 of the second cylinder 42 is extended and retracted in real time each time clamping is performed to complete the clamping operation; or, the power arm 422 of the second cylinder 42 is kept retracted for a long time, and the power arm 412 of the first cylinder 41 is extended and retracted in real time each time clamping is performed to complete the clamping operation.

[0053] For example, when the current batch of objects to be clamped is relatively wide, the power arm 412 of the first cylinder 41 is kept extended for a long time, and the power arm 422 of the second cylinder 42 is extended and retracted in real time each time clamping is performed to complete the clamping operation.

[0054] For example, when the objects to be clamped in the current batch are of varying widths, the power arms of the first cylinder 41 and the second cylinder 42 are controlled to extend and retract in real time to complete an adaptive clamping operation.

[0055] As can be seen from the above, in the clamping and flipping device 100 provided in this embodiment, the control of the opening stroke and clamping stroke of the clamping and flipping part is more flexible, and the adjustment of the clamping area that can be covered is also more flexible, which can quickly adapt to clamped objects of different widths and adapt to a wider range of application needs.

[0056] In addition, in the clamping and flipping device provided in the first embodiment above, the cylinder body of the second cylinder serves as the component that drives the second clamping and flipping part to move. The cylinder body itself can provide a fixed connection position, so there is no need to provide additional mechanisms such as connecting blocks for connecting the second clamping and flipping part as the end of the cylinder power arm in the prior art.

[0057] Furthermore, the clamping and flipping device provided in Embodiment 1 is particularly suitable for the following application scenarios: when the clamped object is conveyed and positioned at a station on an assembly line, it is often detected by a sensor whether a certain end of the product (e.g., the front end in the conveying direction) has reached the sensor's sensing position. If it has reached the sensing position, the position of the product on the assembly line is also positioned based on that positioning end. During clamping, one of the rotating clamping parts (e.g., the first rotating clamping part 10 in this embodiment) can accurately fit into the aforementioned positioning end of the clamped object; then, a rotating clamping part (e.g., the second rotating clamping part 20 in this embodiment) is used to clamp the object in a manner that adapts to the width of the clamped object.

[0058] Example 2

[0059] refer to Figure 1 As shown, Embodiment 2 provides another clamping and flipping device, which also includes a support frame 30, a first clamping and flipping part 10, a second clamping and flipping part 20, and a clamping drive assembly 40. The clamping drive assembly 40 also includes a first cylinder 41, a second cylinder 42, and a connector 43. The ends of the power arms of the first cylinder 41 and the second cylinder 42 are also arranged facing each other and fixedly connected by the connector 43.

[0060] The difference between the clamping and flipping device provided in Embodiment 2 and Embodiment 1 is that: both the first clamping and flipping part 10 and the second clamping and flipping part 20 are movably disposed on the support frame 30 along the X-axis; the support frame 30 is provided with a locking mechanism. Figure 1 (Not shown in the image), the cylinder body 411 of the first cylinder 41, the cylinder body 421 of the second cylinder 42, and the connecting member 43 are selectively locked onto the support frame 30 by the locking mechanism.

[0061] The support frame 30 is provided with a slide rail along the X-axis. The slide rail can be a whole section of slide rail that runs through both ends of the support frame, or it can be two sections of slide rail that guide the first cylinder 41 and the second cylinder 42 respectively. The cylinder body 411 of the first cylinder 41 and the cylinder body 421 of the second cylinder 42 are respectively set on the slide rail by sliders.

[0062] In addition, as a preferred embodiment, the locking mechanism is fixedly installed at both ends and the middle part of the support frame 30, and the three locking mechanisms can be controlled to lock the cylinder body 411 of the first cylinder 41, the cylinder body 421 of the second cylinder 42, or the connecting piece 43 onto the support frame 30.

[0063] In the clamping and flipping device 100 provided in the above embodiment 2, the clamping drive assembly 40 adopts a structure with two cylinders and the driving ends of the two cylinders connected together; at the same time, the cylinder bodies of the two cylinders and the two clamping and flipping parts connected thereto can move along the X-axis; in this way, according to the actual application scenario, one of the cylinder bodies of the first cylinder, the cylinder bodies of the second cylinder, and the connecting parts can be selected as the base point for fixing, and the other parts can be used as the movable side, making the use more flexible. An example is given below.

[0064] For example, when the cylinder body 411 of the first cylinder 41 is selected as the fixed base point and fixed to the support frame 30 using the locking mechanism, the maximum clamping stroke of the cylinder body 421 of the second cylinder 42 and the second clamping and flipping part 20 is the stroke of two cylinder power arms, and can be adjusted in stages; or, when the cylinder body 421 of the second cylinder 42 is selected as the fixed base point and fixed to the support frame 30 using the locking mechanism, the maximum clamping stroke of the cylinder body 411 of the first cylinder 41 and the first clamping and flipping part 10 is the stroke of two cylinder power arms, and can be adjusted in stages.

[0065] For example, when the connector 43 is selected as the fixed base point and fixed to the support frame 30 by the locking mechanism, the cylinder body 411 and the first clamping and flipping part 10 of the first cylinder 41, and the cylinder body 421 and the second clamping and flipping part 20 of the second cylinder 42 can each perform the clamping operation with the stroke of one cylinder power arm.

[0066] Similarly, in the clamping and flipping device 100 provided in the above embodiment 2, the cylinder body is used as the component that drives the corresponding clamping and flipping part to move. The cylinder body itself can provide a fixed connection position, and there is no need to provide additional mechanisms such as a connecting block for connecting the second clamping and flipping part as the end of the cylinder power arm in the prior art.

[0067] Example 3

[0068] like Figure 2 As shown, Embodiment 3 provides a transfer device, including a guide rail 50, a moving frame 60, and a clamping and flipping device 100 as described in Embodiment 1 or Embodiment 2 (in combination with...). Figure 1 The movable frame 60 is movably mounted on the guide rail 50, and the clamping and flipping device 100 is mounted on the movable frame 60. In addition, the transfer device provided in Embodiment 3 also includes a linear servo module 70 that drives the movable frame 60 to move along the guide rail 50.

[0069] Combination Figure 3As shown, in this embodiment, the guide rail 50 includes a first guide rail 51 and a second guide rail 52 arranged in parallel. The movable frame 60 includes a first support leg 61, a second support leg 62, and an assembly plate 63. The first support leg 61 and the second support leg 62 are movably disposed on the first guide rail 51 and the second guide rail 52, respectively. The two ends of the assembly plate 63 are respectively disposed on the first support leg 61 and the second support leg 62. The clamping and flipping device 100 is disposed on the assembly plate 63. The guide rail 50 is arranged in the left-right direction, and the assembly plate 63 is arranged in the front-back direction. The first clamping and flipping part 10 and the second clamping and flipping part 20 are located on the lower side of the assembly plate 63.

[0070] The transfer device provided in Embodiment 3 can realize the functions of clamping, flipping and transferring items across production lines when the guide rail 50 spans at least two production lines. Compared with the current transfer devices with only handling functions, the transfer device provided in Embodiment 3 can also realize the automatic flipping of the clamped items while transferring, which greatly saves manpower and improves production efficiency.

[0071] In addition, the mobile frame 60 also includes a first lifting adjustment mechanism 64 and a second lowering adjustment mechanism 65. The two ends of the assembly plate 63 are respectively mounted on the first support leg 61 and the second support leg 62 via the first lifting adjustment mechanism 64 and the second lowering adjustment mechanism 65. By setting up the lifting adjustment mechanism, the assembly plate 63 and the clamping and flipping device 100 mounted on it can be adjusted up and down, thereby avoiding some interference during the transfer process and making the transfer operation easier.

[0072] The above embodiments are merely a full disclosure and not a limitation of the present invention. Any substitution of equivalent technical features based on the creative intent of the present invention without creative effort should be considered as within the scope of this application.
