Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and particularly relates to a flipping mechanism with a preloading function and a flipping conveyor line. Background Art

[0002] In a cylindrical lithium battery production line, there are many workstations where the battery needs to be flipped and held, and then process operations are carried out. Taking inkjet coding as an example, the incoming battery needs to be flipped 90° from the vertical state to the horizontal state, and then horizontally translated at a constant speed through a coding mechanism (for example, a UV inkjet gun / laser engraving code), after the code pattern information is applied, it is flipped back to the original state and enters the next process. Currently, a cam groove is used to directly drive the flipping mechanism to achieve the flipping action, and the flipping angle is controlled by controlling the cam stroke. The existing flipping mechanism has the following problems during operation: high precision requirements for parts, difficult installation and debugging, and after the flipping mechanism operates for a long time and undergoes wear and fatigue deformation, if the flipping effect cannot reach the expected angle, a complete set of parts needs to be replaced. Summary of the Invention The purpose of the present invention is to provide a flipping mechanism with a preloading function and a flipping conveyor line to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0003] The technical solution adopted to solve the above technical problems: The present invention provides a flipping mechanism with a preloading function, including: A flipping base; A carrier, rotatably installed on the flipping base; A preloading swing arm, one end of the preloading swing arm is rotatably arranged on the flipping base, the rotation center of the preloading swing arm is arranged in the same direction as the rotation center of the carrier, and the other end of the preloading swing arm is provided with a follower part; A flipping limit component, including a first limit component arranged on the flipping base, the first limit component is located on the rotation trajectory of the carrier, and the first limit component is used to abut against the side surface of the carrier along the first rotation direction to limit the carrier to a first preset rotation position; A preloading elastic member, acting between the preloading swing arm and the carrier, the preloading elastic member is used to apply an acting elastic force between the preloading swing arm and the carrier, so that the carrier rotates following the preloading swing arm, and the carrier abuts against the first limit component.

[0004] The beneficial effect of the flipping mechanism of the present invention is: During use, it slides and mates with the follower part through an external guiding structure. The follower part drives the preloading swing arm to rotate. Under the elastic force of the preloading elastic part, the carrier follows the preloading swing arm and rotates in the first rotation direction to realize the flipping of the workpiece clamped on the carrier. When the carrier rotates to the first preset rotation position, due to the elastic telescopic characteristic of the preloading elastic part, the preloading swing arm also rotates a certain angle in the first rotation direction to increase the acting elastic force applied by the preloading elastic part between the preloading swing arm and the carrier, so that the side surface of the carrier in the first rotation direction remains in contact with the first limiting part to be limited at the first preset rotation position. The present invention positions the first preset rotation position of the carrier through the first limiting part, so that the flipping effect of the carrier can reach the expected angle. The external guiding structure does not directly drive the carrier to the required angle. First, it drives the preloading swing arm to make the rotation angle of the preloading swing arm exceed the required angle, and then the preloading swing arm drives the carrier to flip through the preloading elastic part. Under the limitation of the first limiting part on the carrier, precise control of the required angle is achieved, without the need for precise driving control of the preloading swing arm, reducing the requirements for part precision and the difficulty of installation and debugging.

[0005] As a further improvement of the above technical solution, the carrier is rigidly connected with a flipping swing arm. The preloading elastic part is connected between the flipping swing arm and the preloading swing arm. The flipping swing arm is provided with a first abutting part arranged in the first rotation direction, and the preloading swing arm is provided with a second abutting part arranged in the second rotation direction. The acting elastic force applied by the preloading elastic part is also used to make the second abutting part and the first abutting part approach and abut against each other.

[0006] As a further improvement of the above technical solution, the rotation center of the preloading swing arm is concentrically arranged with the rotation center of the carrier.

[0007] As a further improvement of the above technical solution, the carrier is connected with a rotating shaft. The carrier is rotationally connected with the flipping base through the rotating shaft. The flipping swing arm is rotationally connected to the rotating shaft, and the preloading swing arm is rotationally connected to the rotating shaft.

[0008] As a further improvement of the above technical solution, it further includes a reset elastic part. The reset elastic part is connected between the preloading swing arm and the flipping base. The reset elastic part is used to apply a reset elastic force for the preloading swing arm to reset in the second rotation direction.

[0009] As a further improvement of the above technical solution, the flipping limiting assembly further includes a second limiting part. The second limiting part is located on the rotation trajectory of the carrier. The second limiting part is used to abut against the side surface of the carrier in the second rotation direction to limit the carrier at the second preset rotation position.

[0010] As a further improvement of the above technical solution, the second limiting member is movably adjustable to adjust the rotation angle of the carrier along the second rotation direction.

[0011] As a further improvement of the above technical solution, the first limiting member is movably adjustable to adjust the rotation angle of the carrier along the first rotation direction.

[0012] The present invention also provides a flipping conveyor line, which includes a plurality of the flipping mechanisms as described above, and further includes a conveying mechanism and a guiding mechanism. The conveying mechanism is used to drive the plurality of flipping mechanisms to move along the conveying direction. The guiding mechanism includes a guiding slide rail extending along the conveying direction, and the guiding slide rail is slidably matched with the follower part.

[0013] As a further improvement of the above technical solution, the guiding slide rail includes a flipping section, a holding section and a reset section that are sequentially connected along the conveying direction. The flipping section and the reset section are respectively arc-shaped, and the flipping section and the reset section are mirror images of each other. The holding section is linearly arranged and parallel to the conveying direction.

Detailed implementation mode

[0016] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0017] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up and down is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0018] In the description of the present invention, "a plurality of" refers to more than two. If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence of the indicated technical features.

[0019] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, and connection should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the drawings. Obviously, the following described embodiments are some embodiments of the present invention, not all embodiments.

[0021] In the existing production line, there are many workstations. Some workstations need to flip and hold workpieces and then perform process operations. For example, in the cylindrical lithium battery 600 production line, taking inkjet coding as an example, the incoming battery 600 needs to be flipped 90° from the vertical state to the horizontal state, and then move horizontally at a constant speed through the coding mechanism (for example, UV inkjet gun / laser coding). After the code pattern information is applied, it is flipped back to the original state and enters the next process. The existing mechanism directly drives the flipping mechanism 900 through a cam groove to achieve the flipping action, and controls the flipping angle by controlling the stroke of the cam groove. On the premise that multiple workstations pass through the same cam groove, it is necessary to ensure the consistency of the flipping mechanism 900, which results in high part precision, difficult installation and debugging, and high processing costs. Moreover, after the flipping mechanism 900 runs for a long time and undergoes wear and fatigue deformation, if the flipping effect cannot meet the expectations, a complete set of parts needs to be replaced. Therefore, the present invention proposes a flipping mechanism 900 with a preloading function, which solves the problems of high part precision requirements and difficult installation and debugging. Moreover, after the parts are worn, only simple adjustment is required to restore the production requirements, without the need to replace a complete set of parts, saving processing costs, reducing the installation difficulty, and shortening the maintenance time.

[0022] Referring to Figures 1 to 5 , the flipping mechanism 900 of the present invention includes: a flipping base 100, a carrier 200, a preloading swing arm 300, a flipping limit assembly 400, and a preloading elastic member 500.

[0023] In this embodiment, the flipping base 100 is only used for translation and does not rotate, fixing each rotation center and the mounting bases of various accessories, and driving the operation of a single workstation.

[0024] As Figure 1 shown, the carrier 200 is used for clamping the conveyed workpieces. In this embodiment, the carrier 200 is used for clamping the battery 600. In some other embodiments, other workpieces can be clamped. In this embodiment, the carrier 200 is rotatably mounted on the flipping base 100. Taking the rotation center of the carrier 200 extending in the front-rear direction as an example, in some other embodiments, the rotation center of the carrier 200 can extend in other directions.

[0025] One end of the preloading swing arm 300 of the present invention is rotatably provided on the flipping base 100, and the rotation center of the preloading swing arm 300 is concentric with the rotation center of the carrier 200. The other end of the preloading swing arm 300 is provided with a follower portion 310, and the follower portion 310 is used for sliding cooperation with an external guiding structure. Under the translation of the flipping base 100, it moves along a cam-like trajectory to drive the rotation of the preloading swing arm 300.

[0026] The rotation center of the preloading swing arm 300 in this embodiment is concentric with the rotation center of the carrier 200, which is convenient for the arrangement of other components and makes the structure more compact. In some other embodiments, the rotation center of the preloading swing arm 300 and the rotation center of the carrier 200 can be eccentrically arranged.

[0027] Moreover, the preloading swing arm 300 can be rotatably connected to the carrier 200 to realize the rotation of the preloading swing arm 300 relative to the flipping base 100. Or, the preloading swing arm 300 is rotatably connected to the flipping base 100.

[0028] As Figure 1 shown, the carrier 200 in this embodiment is connected with a rotating shaft 210. The carrier 200 is rotatably connected to the flipping base 100 through the rotating shaft 210, and the preloading swing arm 300 is rotatably connected to the rotating shaft 210.

[0029] As Figure 1 shown, the flipping limiting component 400 of the present invention includes a first limiting component 410 arranged on the flipping base 100. The first limiting component 410 is located on the rotation track of the carrier 200. The first limiting component 410 is used to abut against the side surface of the carrier 200 along the first rotation direction to limit the carrier 200 to the first preset rotation position. It can be understood that, as Figure 3 and 5 shown, when the carrier 200 rotates to the set position along the first rotation direction, the carrier 200 abuts against the first limiting component 410 to block the rotation of the carrier 200 in the first rotation direction. At this time, the position where the carrier 200 is located is the first preset rotation position. When the carrier 200 is in the first preset rotation position, the workpiece is flipped to the set posture. In this embodiment, it is defined that when the carrier 200 is in the first preset rotation position, the workpiece is flipped to the horizontal posture, that is, the carrier 200 is in the horizontal state.

[0030] The preloading elastic member 500 acts between the preloading swing arm 300 and the carrier 200. The preloading elastic member 500 is used to apply an acting elastic force between the preloading swing arm 300 and the carrier 200, so that the carrier 200 rotates following the preloading swing arm 300, and the carrier 200 abuts against the first limiting component 410. It can be understood that when the preloading swing arm 300 rotates, the carrier 200 is driven to rotate together through the preloading elastic member 500. The acting elastic force applied by the preloading elastic member 500 between the preloading swing arm 300 and the carrier 200 is used to realize force transmission. When the carrier 200 abuts against the first limiting component 410, the acting elastic force applied by the preloading elastic member 500 makes the carrier 200 keep abutting against the first limiting component 410 to realize the limit of the carrier 200 along the first rotation direction. At this time, the preloading swing arm 300 can further rotate.

[0031] In use, it is slidably mated with the follower part 310 through an external guiding structure. The follower part 310 drives the preloading swing arm 300 to rotate. Under the elastic force of the preloading elastic member 500, the carrier 200 follows the preloading swing arm 300 to rotate in the first rotation direction, so as to realize the flipping of the workpiece clamped on the carrier 200. As Figure 3 and Figure 5 shown, when the carrier 200 rotates to the first preset rotation position, due to the elastic telescopic characteristic of the preloading elastic member 500, the preloading swing arm 300 also rotates a certain angle in the first rotation direction, so as to increase the acting elastic force applied by the preloading elastic member 500 between the preloading swing arm 300 and the carrier 200, so that the side surface of the carrier 200 in the first rotation direction remains in contact with the first limiting member 410, so as to be limited to the first preset rotation position, so that the workpiece can be accurately flipped to the horizontal posture. In the present invention, the first preset rotation position of the carrier 200 is positioned by the first limiting member 410, so that the flipping effect of the carrier 200 can reach the expected angle. The external guiding structure does not directly drive the carrier 200 to the required angle. First, the preloading swing arm 300 is driven, so that the rotation angle of the preloading swing arm 300 exceeds the required angle, and then the preloading swing arm 300 drives the carrier 200 to flip through the preloading elastic member 500. Under the limitation of the first limiting member 410 on the carrier 200, accurate control of the required angle is achieved, without precise driving control of the preloading swing arm 300, reducing the requirements for part accuracy and the difficulty of installation and debugging.

[0032] Furthermore, as Figure 1 shown, the carrier 200 of this embodiment is rigidly connected with a flipping swing arm 700. The preloading elastic member 500 is connected between the flipping swing arm 700 and the preloading swing arm 300. The preloading swing arm 300 drives the flipping swing arm 700 to flip through the preloading elastic member 500, so as to drive the carrier 200 to flip. The carrier 200 flips by the same number of degrees as the flipping swing arm 700 flips.

[0033] Moreover, the flipping swing arm 700 of this embodiment is connected to the rotating shaft 210 to form an existing flipping mechanism 900. In this embodiment, on the basis of the existing flipping mechanism 900, an additional preloading swing arm 300 and a preloading elastic member 500 can be added. The preloading elastic member 500 of this embodiment adopts a spring structure. In some other embodiments, the preloading elastic member 500 can adopt other elastic structures.

[0034] As Figure 5As shown, the flipping swing arm 700 of this embodiment is provided with a first abutting portion 710 arranged in the first rotation direction, and the preloading swing arm 300 is provided with a second abutting portion 320 arranged in the second rotation direction, wherein the first rotation direction and the second rotation direction are arranged in opposite directions. The acting elastic force applied by the preloading elastic member 500 is also used to make the second abutting portion 320 and the first abutting portion 710 approach and abut against each other. On the one hand, the preloading elastic member 500 can provide a preloading limiting elastic force for the carrier 200, and on the other hand, it can also provide a reset elastic force for the flipping swing arm 700. When the carrier 200 does not abut against the first limiting member 410, the second abutting portion 320 remains in close contact with the first abutting portion 710. At the initial stage of the flipping of the preloading swing arm 300, the flipping swing arm 700 rotates synchronously with the preloading swing arm 300, and when the preloading swing arm 300 flips and resets along the second rotation direction, the flipping swing arm 700 is driven to flip and reset along the second rotation direction by the abutting of the second abutting portion 320 and the first abutting portion 710, so as to drive the carrier 200 to flip and reset.

[0035] As Figure 5 shown, the second abutting portion 320 of this embodiment is an inclined step, and the first abutting portion 710 is the side wall of the flipping swing arm 700. In some other embodiments, the second abutting portion 320 and the first abutting portion 710 can be other structures, as long as they can play the roles of contact, limiting, and restricting the one-way phase difference.

[0036] Furthermore, as Figure 1 shown, it further includes a reset elastic member 800. The reset elastic member 800 is connected between the preloading swing arm 300 and the flipping base 100. The reset elastic member 800 is used to apply a reset elastic force for the preloading swing arm 300 to reset along the second rotation direction, and the preloading swing arm 300 is urged to reset along the second rotation direction through the reset elastic member 800 to achieve auxiliary reset.

[0037] The reset elastic member 800 of this embodiment adopts a spring structure. In some other embodiments, the preloading elastic member 500 can adopt other elastic structures.

[0038] Regarding the limiting of the reset state of the carrier 200, as Figure 1 shown, the flipping limiting assembly 400 of this embodiment further includes a second limiting member 420. The second limiting member 420 is located on the rotation trajectory of the carrier 200, as Figure 1 、 Figure 2 and Figure 4As shown, the second limiting component 420 is used to abut against the side surface of the carrier 200 along the second rotation direction to limit the carrier 200 to the second preset rotation position. It can be understood that when the carrier 200 rotates to the set position along the second rotation direction, the carrier 200 abuts against the second limiting component 420 to block the rotation of the carrier 200 in the second rotation direction. At this time, the position where the carrier 200 is located is the second preset rotation position. When the carrier 200 is in the second preset rotation position, the workpiece is reset and flipped to the set posture. In this embodiment, it is defined that when the carrier 200 is in the second preset rotation position, the workpiece is flipped to the vertical posture, that is, the carrier 200 is in the vertical state.

[0039] As Figure 4 shown, when the carrier 200 is in the vertical state, the preloading elastic member 500 maintains the initial stretched length, causing the second abutting portion 320 to abut against the first abutting portion 710, and the reset elastic member 800 maintains the initial stretched length, causing the second abutting portion 320 to abut against the first abutting portion 710. The carrier 200 abuts tightly against the second limiting component 420, causing the carrier 200 to maintain the vertical state.

[0040] As Figure 5 shown, when the carrier 200 is in the horizontal state, the second abutting portion 320 is separated from the first abutting portion 710. At this time, the carrier 200 is always in close contact with the first limiting component 410, and both the reset elastic member 800 and the preloading elastic member 500 are stretched.

[0041] The second limiting component 420 of this embodiment is movably and adjustably arranged to adjust the rotation angle of the carrier 200 along the second rotation direction. It can be understood that during installation and debugging, according to the installation error between components, the vertical state angle of the carrier 200 can be limited by adjusting the second limiting component 420.

[0042] In addition, the first limiting component 410 is movably and adjustably arranged to adjust the rotation angle of the carrier 200 along the first rotation direction. It can be understood that during installation and debugging, according to the installation error between components, the horizontal state angle of the carrier 200 can be limited by adjusting the first limiting component 410. The first limiting component 410 in this embodiment becomes the adjustment for the termination of the flipping movement of the carrier 200 along the first rotation direction, rather than being limited by the cam groove track of the original mechanism, realizing the adjustable horizontal state, and thus realizing the fine adjustment of the required angle to adjust the flipping angle of the carrier 200.

[0043] The first limiting component 410 and the second limiting component 420 of this embodiment adopt limiting screws. Among them, the first limiting component 410 is adjustable along the vertical direction, while the second limiting component 420 is adjustable along the horizontal direction.

[0044] In the original flipping mechanism 900, the flipping swing arm 700 in it presses the follower part 310 against the cam groove by means of a spring, requiring a large amount of spring stretch. Under the same specifications, the larger the allowable spring stretch, the longer the original length, the larger the space span, the lower the stiffness, the weaker the ability to resist vibrations, jitters and other interferences, and the shorter the service life. Parts often need to be replaced. In the flipping mechanism 900 of this embodiment, the preloading swing arm 300 moving along with the cam groove is applied with force jointly by the reset elastic member 800 and the preloading elastic member 500.

[0045] Among them, the reset elastic member 800 acts throughout the flipping process, playing a role in assisting the swing arm to return to its position and damping vibration. Since a large amount of stretch is required but not a large restoring force, a spring with a small stiffness and a large allowable stretch is selected, which increases the service life and reduces the space span.

[0046] The preloading elastic member 500 only acts on the final required angle to provide sufficient pressure to press against the cam groove. Since the required stretching length is small and only sufficient elastic force is provided, a spring with a high stiffness and a small stretch is selected, which saves space, increases the stability of the mechanism and the anti-interference ability, and extends the service life.

[0047] After parts are worn and fatigued and deformed, maintenance time can still be reduced by replacing springs and adjusting.

[0048] As Figure 6 shown, the present invention also proposes a flipping conveyor line, which includes a plurality of flipping mechanisms 900, and also includes a conveying mechanism 1000 and a guiding mechanism 2000. Among them, the conveying mechanism 1000 is used to drive the plurality of flipping mechanisms 900 to move along the conveying direction, and the guiding mechanism 2000 includes a guiding slide rail 2100 extending along the conveying direction. The guiding slide rail 2100 is slidably matched with the follower part 310. The guiding slide rail 2100 of this embodiment is of a cam groove structure.

[0049] The conveying mechanism 1000 is in transmission connection with the flipping base 100 to drive the flipping base 100 to move along the conveying direction.

[0050] The guiding slide rail 2100 of this embodiment includes a flipping section 2110, a holding section 2120 and a reset section 2130 connected in sequence along the conveying direction. The flipping section 2110 and the reset section 2130 are respectively arranged in an arc shape, and the flipping section 2110 and the reset section 2130 are mirror images of each other. The holding section 2120 is arranged in a straight line and parallel to the conveying direction. When the flipping mechanism 900 passes through the flipping section 2110, the carrier 200 is flipped from the vertical state to the horizontal state. When the flipping mechanism 900 passes through the holding section 2120, the carrier 200 maintains the horizontal state and moves horizontally. When the flipping mechanism 900 passes through the reset section 2130, the carrier 200 is flipped from the horizontal state to the vertical state.

[0051] As Figure 6As shown in the figure, the principle of action change during the movement of the flipping mechanism 900 along the guiding slide rail 2100 is as follows: Before the follower part 310 enters the flipping section 2110, the preloading elastic member 500 maintains its initial stretched length, causing the second abutting part 320 to abut against the first abutting part 710, and the reset elastic member 800 also maintains its initial stretched length, causing the second abutting part 320 to abut against the first abutting part 710. The carrier 200 abuts tightly against the second limiting member 420, keeping the carrier 200 in a vertical state; During the process when the follower part 310 passes through the flipping section 2110, the preloading swing arm 300 rotates in the first rotation direction, and the carrier 200 enters the overturned state. At this time, the second abutting part 320 and the first abutting part 710 always abut tightly against each other until the carrier 200 flips to the horizontal limit position. The reset elastic member 800 is gradually stretched from its initial length, and the restoring force gradually increases, while the preloading elastic member 500 always maintains its initial telescopic length. The preloading swing arm 300 drives the flipping swing arm 700 to flip through the preloading elastic member 500 to drive the carrier 200 to flip; When the follower part 310 passes through the end section of the flipping section 2110, that is, it enters the preloading and stretching state. At this time, the carrier 200 abuts against the first limiting member 410. The preloading swing arm 300 continues to rotate in the first rotation direction, and the second abutting part 320 separates from the first abutting part 710. The reset elastic member 800 is still gradually stretched, with a relatively small amount of stretching, while the preloading elastic member 500 begins to be gradually stretched until the flipping section 2110 drives the follower part 310 to the lowest limit position. At this time, the preloading elastic member 500 is stretched to the longest and maintains this length throughout the horizontal state; During the process when the follower part 310 passes through the holding section 2120, the carrier 200 is conveyed while maintaining a horizontal state.

[0052] When the follower part 310 passes through the beginning section of the reset section 2130, that is, it enters the preloading and retracting state. The preloading swing arm 300 rotates in the second rotation direction, and the second abutting part 320 remains separated from the first abutting part 710. At this time, the carrier 200 still always abuts against the first limiting member 410. The reset elastic member 800 retracts slightly, while the preloading elastic member 500 gradually retracts until the second abutting part 320 abuts tightly against the first abutting part 710. At this time, the preloading elastic member 500 returns to its initial extended state.

[0053] After the follower part 310 passes through the beginning section of the reset section 2130, it enters the flipping-back state. The preloading swing arm 300 rotates in the second rotation direction, and the second abutting part 320 and the first abutting part 710 always abut tightly against each other during this process. The carrier 200 separates from the first limiting member 410 until the carrier 200 abuts tightly against the second limiting member 420 and returns to the vertical state. The reset elastic member 800 retracts a large amount to its initial stretched length, while the preloading elastic member 500 maintains its initial telescopic length.
