[0039] See also Figure 1 , Figure 1 A schematic diagram of the structure of a double-station intermittent motion device in an embodiment of the present application is shown. A double-station intermittent motion device provided in an embodiment of the present application includes a driving mechanism 100, a transmission mechanism 200, a first actuator 300 and a second actuator 400, which realizes intermittent feeding and intermittent processing operations on two independent stations through a magnetic drive and an incompletely meshing transmission mechanism.
[0040] Specifically, the driving mechanism 100 includes a magnetic driving member 110, a magnetic follower 120 and a pushing portion 130. The magnetic follower 120 is arranged on one side of the magnetic driving member 110 and has a polarity opposite to that of the magnetic driving member 110. The pushing portion 130 is arranged on the magnetic driving member 110. One end of the transmission mechanism 200 is used for incomplete meshing connection with the magnetic driving member 110 and abutting against the pushing portion 130. The first actuator 300 is arranged on one side of the magnetic driving member 110 and connected to the other end of the transmission mechanism 200. The second actuator 400 is arranged on one side of the magnetic follower 120 and connected to the magnetic follower 120.
[0041] In the specific implementation process, when the magnetic driving member 110 rotates, the pushing part 130 rotates synchronously, pushing the transmission mechanism 200 to perform a small initial rotation. Subsequently, the transmission mechanism 200 and the magnetic driving member 110 are not completely engaged, so that the transmission mechanism 200 rotates at a large angle and transmits power to the first actuator 300, driving it to perform intermittent material feeding operation, thereby realizing the operation of the first station.
[0042] Furthermore, when the magnetic driving member 110 rotates, the distance between the magnetic driving member 110 and the magnetic follower 120 changes. Since the polarities of the two are opposite, the magnetic repulsive force between the two changes, thereby driving the second actuator 400 to perform linear reciprocating motion, realizing intermittent processing operations, and realizing the operation of the second workstation.
[0043] In one embodiment, the magnetic driving member 110 can be made of a strong magnetic material with stable magnetism to ensure the effectiveness of magnetic force transmission. The magnetic driving member 110 is configured as a rotatable component, and a toothed structure for incomplete meshing with the transmission mechanism 200 is provided on its surface.
[0044] In one embodiment, the magnetic follower 120 may also be made of a strong magnetic material, but with a polarity opposite to that of the magnetic driver 110 to achieve magnetic repulsion.
[0045] In one embodiment, the pushing portion 130 is disposed on the magnetic driving member 110 and rotates synchronously with the magnetic driving member 110 to push the transmission mechanism 200 to rotate and partially mesh with the magnetic driving member 110 .
[0046] In one embodiment, the transmission mechanism 200 is used for incomplete meshing connection with the magnetic driving member 110. Specifically, the transmission mechanism 200 is an incomplete gear 220 or a rack, and some teeth of the gear 220 correspond to teeth or tooth grooves on the magnetic driving member 110, so that when the magnetic driving member 110 rotates, the transmission mechanism 200 can be intermittently rotated at a large angle through a small rotation of the pusher 130.
[0047] In one embodiment, the first actuator 300 is disposed on one side of the magnetic driving member 110 and is connected to the magnetic driving member 110 through the transmission mechanism 200. When the transmission mechanism 200 rotates, the first actuator 300 is driven to perform intermittent motion to achieve the function of intermittent material feeding. In this embodiment, the specific form of the first actuator 300 can be replaced according to processing requirements, such as a clamping plate 310, etc.
[0048] In one embodiment, the second actuator 400 is disposed on one side of the magnetic follower 120 and is directly connected to the magnetic follower 120. Since the repulsive force between the magnetic driving member 110 and the magnetic follower 120 changes with the distance between the two, when the magnetic driving member 110 rotates, the magnetic follower 120 is acted upon by the changing repulsive force, thereby achieving linear reciprocating motion. In this embodiment, the specific form of the second actuator 400 can also be changed according to processing requirements.
[0049] As described above, through the cooperation of the driving mechanism 100, the transmission mechanism 200, the first actuator 300 and the second actuator 400, the function of double-station intermittent motion is realized, thereby improving production efficiency. The first actuator 300 and the second actuator 400 are both amorphous structures and can be replaced according to specific processing conditions, so that the device has the ability to work in multiple conditions. In addition, the repulsive effect of magnetic force is used to replace the traditional cam mechanism to avoid frictional contact between the roller and the cam, thereby reducing the problem of reduced motion accuracy caused by friction.
[0050] Combination Figure 1 As shown, Figure 1 Schematic diagram of the structure of a double-station intermittent motion device provided in an embodiment of the present application. In some embodiments, the magnetic drive member 110 is an irregular structure, and the magnetic drive member 110 includes a first portion having a first radius and a second portion having a second radius, the first portion and the second portion are arranged opposite to each other, and the first radius is greater than the second radius.
[0051] Specifically, the magnetic driving member 110 includes a first part and a second part with different radii, wherein the first radius is larger than the second radius, forming an asymmetric structure, so that the magnetic driving torque changes, thereby driving the magnetic follower 120 to produce different displacements.
[0052] In a specific implementation process, when the magnetic driver 110 rotates, the first part approaches or the second part moves away from the magnetic follower, resulting in an increase in the repulsive force between the magnetic driver 110 and the magnetic follower 120, thereby increasing the displacement of the magnetic follower 120. The first part moves away from or the second part approaches the magnetic follower 120, resulting in a decrease in the repulsive force between the magnetic driver 110 and the magnetic follower 120, thereby reducing the displacement of the magnetic follower 120, thereby achieving reciprocating motion of the magnetic follower 120 and intermittent motion.
[0053] In one embodiment, the magnetic driving member 110 is composed of a permanent magnet 121, and its shape is set to include a first part with a first radius and a second part with a second radius, forming a non-uniform circular or annular structure, so that when the magnetic driving member 110 rotates, the magnetic force application area and torque of the magnetic driving member 110 on the magnetic follower 120 are different.
[0054] In one embodiment, the magnetic follower 120 is also made of a permanent magnet 121 , but its shape and size must match the magnetic driver 110 to ensure sufficient magnetic coupling between the two.
[0055] Combination Figure 1 As shown, Figure 1 Schematic diagram of the structure of a double-station intermittent motion device provided in an embodiment of the present application. In some embodiments, the transmission mechanism 200 includes an extension portion 210 .
[0056] Specifically, the extension part 210 is arranged horizontally, and the pushing part 130 is arranged longitudinally. The extension part 210 is used to abut against the pushing part 130, so as to push the extension part 210 to drive the transmission mechanism 200 to rotate, and incompletely mesh with the magnetic driving part 110 to achieve intermittent motion.
[0057] In one embodiment, the transmission mechanism 200 includes two extending portions 210 spaced apart from each other, and each time the magnetic driving member 110 rotates one circle, the pushing portion 130 abuts against one of the extending portions 210 .
[0058] Specifically, the extension portion 210 may be a plate-shaped or rod-shaped structure, and two extension portions 210 are disposed laterally and spaced apart on a side surface of the transmission mechanism 200 , and the two extension portions 210 are disposed opposite to each other.
[0059] In the specific implementation process, when the pushing portion 130 rotates the first circle, the pushing portion 130 is used to abut against one of the extension portions 210. At this time, the extension portion 210 is lower than the top of the pushing portion 130; the pushing portion 130 rotates, pushing the extension portion 210 and the transmission mechanism 200 to rotate, and the transmission mechanism 200 gradually engages with the magnetic driving member 110 incompletely. At the same time, the horizontal height of the extension portion 210 gradually increases. After the transmission mechanism 200 engages with the magnetic driving member 110 once, the extension portion 210 is higher than the top of the pushing portion 130.
[0060] Furthermore, when the push part 130 continues to rotate for the second circle, the push part 130 is used to abut against another extension part 210. At this time, the other extension part 210 is still lower than the top of the push part 130. The push part 130 continues to rotate, and pushes the other extension part 210 and the transmission mechanism 200 to rotate again. The transmission mechanism 200 is not fully engaged with the magnetic driving member 110 again. At the same time, the level of the other extension 210 is gradually increased. After the transmission mechanism 200 and the magnetic driving member 110 are engaged again, the other extension part 210 is higher than the top of the push part 130. In this reciprocating manner, each time the push part 130 rotates one circle, the transmission mechanism 200 is pushed to engage with the magnetic driving member 110 once, realizing an intermittent motion process.
[0061] In one embodiment, the transmission mechanism 200 includes a transversely disposed extension portion 210 .
[0062] Specifically, when the magnetic driving member 110 rotates forward, the pushing portion 130 abuts against the extension portion 210, and the extension portion 210 is lower than the top of the pushing portion 130; the pushing portion 130 pushes the extension portion 210 to rotate forward, so that the horizontal height of the extension portion 210 gradually increases, and the first actuator 300 is driven to move forward by engaging with the magnetic driving member 110 through the transmission mechanism 200. Further, when the magnetic driving member 110 rotates reversely, the pushing portion 130 abuts against the extension portion 210, and the extension portion 210 is lower than the top of the pushing portion 130; the pushing portion 130 drives the extension portion 210 to rotate reversely, so that the horizontal height of the extension portion 210 gradually decreases, and the first actuator 300 is driven to move reversely by engaging with the magnetic driving member 110 through the transmission mechanism 200, so that the intermittent motion of the first actuator 300 can be achieved while adjusting the motion direction of the first actuator 300.
[0063] Combination Figure 2 As shown, Figure 2 Schematic diagram of the structure of the driving mechanism and the first actuator provided in an embodiment of the present application. In some embodiments, the magnetic driving member 110 includes a permanent magnetic cam 111 and an annular rack 112 , and the annular rack 112 is disposed on a surface of one side of the permanent magnetic cam 111 .
[0064] Specifically, the permanent magnetic cam 111 is made of high-performance permanent magnetic material and has stable magnetic field characteristics. Its shape is set to be a non-standard circle or a profile with specific protrusions, so as to generate a changing magnetic field during the rotation process.
[0065] In this embodiment, the driving mechanism 100 includes a motor, and an output end of the motor is connected to the permanent magnet cam 111 to provide power for the rotation of the permanent magnet cam 111 .
[0066] Furthermore, the annular rack 112 is closely attached to one side surface of the permanent magnet cam 111, and the teeth on the rack are partially distributed, so as to realize meshing transmission with the incomplete gear 220 in the transmission mechanism 200. In this embodiment, the number of teeth and the rack area of the annular rack 112, that is, the distribution range of the rack on the circumference can be adjusted according to the intermittent motion parameters.
[0067] Combination Figure 4 As shown, Figure 4 Schematic diagram of the structure of the driving mechanism provided in one embodiment of the present application. In some embodiments, a ring-shaped cam groove 113 is provided on one side surface of the permanent magnetic cam 111, an inner concave hole is provided at the bottom of the ring-shaped rack 112, one end of the stopper 114 is inserted into the inner concave hole, the ring-shaped rack 112 is installed on the cam groove 113, and the other end of the stopper 114 is embedded in the cam groove 113 to achieve fixed installation of the ring-shaped rack 112, and the stopper 114 is used to prevent the relative rotation of the ring-shaped rack 112, thereby ensuring the synchronous rotation of the two.
[0068] In one embodiment, the transmission mechanism 200 includes an incomplete gear 220 , and the incomplete gear 220 is meshed with the annular rack 112 .
[0069] Specifically, the teeth of the incomplete gear 220 are distributed on a portion of the circumference rather than the entire circumference, so that the incomplete gear 220 can only intermittently mesh with the annular rack 112 during rotation, thereby achieving an intermittent transmission effect. In this embodiment, the material of the incomplete gear 220 is usually high-strength alloy steel to ensure wear resistance and reliability for long-term use.
[0070] In this embodiment, the number of teeth of the incomplete gear 220 can be adjusted according to the intermittent motion requirements.
[0071] In one embodiment, the transmission mechanism 200 further includes a transversely arranged gear shaft 230 .
[0072] Specifically, the gear shaft 230 is arranged horizontally, and one end is fixedly connected to the incomplete gear 220, serving as a support and power transmission path for the rotation of the incomplete gear 220. The other end of the gear shaft 230 is used to connect the first actuator 300 to achieve power output and realize the operation of the first station.
[0073] In one embodiment, the pushing portion 130 includes a baffle 131 , and the extending portion 210 includes a cross bar 211 .
[0074] Specifically, the baffle 131 is longitudinally mounted on the surface of the permanent magnet cam 111 on the side close to the annular rack 112. The cross bar 211 is transversely arranged on the side surface of the incomplete gear 220, and abuts against the baffle 131. When the permanent magnet cam 111 rotates, the baffle 131 rotates synchronously and pushes the cross bar 211 to rotate, so that the incomplete gear 220 meshes with the annular rack 112 and rotates, thereby realizing the output of power.
[0075] In one embodiment, the first actuator 300 includes a clamping plate 310, one end of the gear shaft 230 is connected to the incomplete gear 220, and the other end is connected to the clamping plate 310. When the incomplete gear 220 rotates and drives the gear shaft 230 to rotate, the clamping plate 310 performs intermittent linear motion, which is used for operations such as moving materials, and realizes intermittent motion of the first station.
[0076] As described above, by changing the number of teeth of the incomplete gear 220, the number of teeth of the circular rack, and the rack area, the parameters such as the intermittent motion time and number of times can be flexibly adjusted to meet different production requirements. For example, increasing the number of teeth of the incomplete gear 220 or reducing the number of teeth of the annular rack 112 can extend the time of each intermittent movement; or reducing the number of teeth of the incomplete gear 220 or increasing the number of teeth of the annular rack 112 can shorten the interval time; or, adjusting the rack area can affect the number of intermittent movements.
[0077] Combination Figure 3 As shown, Figure 3 Schematic diagram of the structure of the second actuator provided in an embodiment of the present application. In some embodiments, the double-station intermittent motion device further includes a frame 500, and the frame 500 is arranged on one side of the magnetic follower 120. The magnetic follower 120 includes a permanent magnet 121, and the second actuator 400 includes a connecting rod 410, and the connecting rod 410 is movably arranged on the frame 500, and the connecting rod 410 is connected to the permanent magnet 121.
[0078] Specifically, one side of the frame 500 is provided with an area for installing and supporting the magnetic follower 120. The magnetic follower 120 includes a permanent magnet 121, the polarity of the permanent magnet 121 is opposite to the polarity of the permanent magnet cam 111, and the repulsion between the two drives the permanent magnet 121 to move.
[0079] Furthermore, the second actuator 400 includes a connecting rod 410, which is movably disposed on the frame 500, and one end of the connecting rod 410 is connected to the permanent magnet 121 to convert the reciprocating motion of the permanent magnet 121 into the intermittent motion of the connecting rod 410 to perform the operation required by the second workstation.
[0080] In one embodiment, the frame 500 further includes a guide plate 510 and an elastic member 520 .
[0081] Specifically, the guide plate 510 is vertically arranged on the surface of the frame 500 near the permanent magnet 121, and the side wall of the permanent magnet 121 is slidably matched with the side edge of the guide plate 510. The guide plate 510 is used to limit the movement trajectory of the permanent magnet 121, ensuring that the permanent magnet 121 reciprocates along a predetermined path under the action of the magnetic field.
[0082] Further, one end of the elastic member 520 is connected to the frame 500, and the other end is connected to the connecting rod 410. The elastic member 520 can be a spring, an elastic sheet, etc., to provide a reset force for the connecting rod 410, ensuring that the connecting rod 410 can stably return to the initial position during the reciprocating motion of the permanent magnet 121.
[0083] In the specific implementation process, since the contour of the permanent magnet cam 111 is an irregular shape, the gap distance between the permanent magnet 121 and the permanent magnet cam 111 changes, which in turn causes the repulsive force on the permanent magnet 121 to change. As a result, the permanent magnet 121, under the guidance of the guide plate 510, drives the connecting rod 410 to reciprocate along a predetermined path, thereby realizing intermittent motion of the second workstation.
[0084] In one embodiment, the second actuator 400 further includes a support rod 530 , and the support rod 530 is movably disposed on a surface of the frame 500 close to the permanent magnet 121 .
[0085] Specifically, the support rod 530 is set to be slender, and one end of the support rod 530 is movably set on the surface of the frame 500 near the permanent magnet 121, and is connected by a bearing or a hinge, and can swing or rotate freely within a certain range. The connecting rod 410 is set horizontally, one end of the connecting rod 410 is connected to the permanent magnet 121, and the other end is movably connected to the support rod 530. The support rod 530 is used to support the connecting rod 410, provide an installation position for the connecting rod 410, and ensure the mobility of the connecting rod 410.
[0086] In one embodiment, the connecting rod 410 includes a first section 411 and a second section 412 , and the first section 411 and the second section 412 are bent between them.
[0087] Specifically, the connecting rod 410 is composed of a first section 411 and a second section 412, which are bent at the connection to form a non-linear angle, which can effectively optimize the spatial layout and ensure effective force transmission in a limited space. The first section 411 is connected to the permanent magnet 121, and the second section 412 is movably connected to the support rod 530, ensuring that the connecting rod 410 can perform corresponding operations under the drive of the permanent magnet 121 to achieve intermittent motion of the second station.
[0088] In one embodiment, the frame 500 further includes a support base 540 , which is vertically disposed on a surface of the frame 500 close to the permanent magnet 121 , and the first section 411 and the permanent magnet 121 are disposed on the top of the support base 540 .
[0089] Specifically, a support seat 540 is vertically arranged on the surface of the frame 500 near the permanent magnet 121. The top of the support seat 540 is used to install the permanent magnet 121 and the first section 411 of the connecting rod 410. The first section 411 is placed on the top of the support seat 540 and slidably cooperates with the support seat 540. The permanent magnet 121 is installed above the first section 411. Under the action of the magnetic repulsive force, the permanent magnet 121 and the first section 411 are driven to reciprocate to meet the needs of intermittent motion.
[0090] As described above, by setting the bending connecting rod 410 and the supporting rod 530 in cooperation, not only the stability and flexibility of the intermittent motion are improved, but also the motion path is optimized; setting the supporting seat 540 in cooperation with the connecting rod 410 enhances the stability of the movement.
