Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic loading and unloading equipment, in particular to a self-locking turnover device and loading and unloading device. BACKGROUND

[0002] With the increasing degree of automation, many operations in the production process are replaced by mechanical structures, among which the turnover action is gradually realized by a turnover device, which can accurately turn the workpiece to be turned between two different workstations, so the turnover device is often used in the field of automatic loading and unloading.

[0003] In the prior art, the turnover device is driven by a driving mechanism to realize turnover between at least two workstations, thereby driving the object fixed thereon to switch positions between multiple workstations. However, after the turnover device is turned to the position, force needs to be applied to maintain the position of the turnover device, so that the object thereon can be accurately fixed at the corresponding workstation.

[0004] The existing turnover device generally directly uses the driving mechanism to maintain its position at each different workstation. For example, if the driving mechanism uses a cylinder, it can be continuously supplied with gas. However, on the one hand, when the driving distance of the driving mechanism fluctuates, the turnover device cannot complete the corresponding process at the preset workstation, the stability is poor, and deviation is prone to occur. On the other hand, when the turnover device is applied in automatic loading and unloading equipment, the turnover device needs to participate in the process of loading and unloading goods, so when the driving mechanism supports the turnover device, it not only needs to bear the weight of the turnover device itself, but also needs to bear the weight of the goods to be loaded and unloaded. The driving force required for the driving mechanism is high, the procurement cost of the driving mechanism is increased, and the driving mechanism is continuously working under high load, which is prone to failure.

[0035] In one embodiment, as Figure 1As shown, a turnover device includes a support plate 20, a mounting plate 30, a driving mechanism 40 and a self-locking mechanism 50. The support plate 20 is rotatably connected with the mounting plate 30; the driving mechanism 40 is arranged on the support plate 20, and a driving end of the driving mechanism 40 is drivingly connected with the mounting plate 30 and drives the mounting plate 30 to rotate relative to the support plate 20; the self-locking mechanism 50 is arranged between the support plate 20 and the mounting plate 30, so that the mounting plate 30 is locked in position at least at a work station reached by the turnover.

[0036] Specifically, when the mounting plate 30 and the self-locking mechanism 50 are locked, it is the first work station of the turnover device, and when the mounting plate 30 and the self-locking mechanism 50 are unlocked and counterclockwise turned by ninety degrees, it is the second work station of the turnover device. The self-locking mechanism 50 includes a self-locking rod 51 arranged on the support plate 20. The driving mechanism 40 includes a telescopic cylinder 41 arranged on the support plate 20, and a driving end of the telescopic cylinder 41 is drivingly connected with the mounting plate 30 and drives the mounting plate 30 to turn over, so as to realize the conversion between the two work stations. The mounting plate 30 can be fixedly connected with a jig plate 10, and other mechanisms such as clamping jaws, suction cups and the like can be arranged on the jig plate 10 and complete different processes in different work stations under the driving of the turnover device.

[0037] After the telescopic cylinder 41 drives the mounting plate 30 to turn over to the first work station, the self-locking rod 51 and the mounting plate 30 are locked. The self-locking rod 51 can provide a force to resist the turning over of the mounting plate 30 caused by the gravity of the mounting plate 30 itself, the jig plate 10 and other additional materials, etc., to connect and fix the support plate 20 and the mounting plate 30 and maintain the stability of the turnover device in the current work station. The driving mechanism 40 only needs to provide driving force for turning over, and does not need to continuously provide power to maintain the stability of the work station after turning over, thereby reducing the requirement for driving force of the driving mechanism 40, reducing the failure rate of the driving mechanism 40, improving the safety of the loading and unloading process, saving the production cost of the turnover device, and reducing the additional maintenance and replacement cost.

[0038] The self-locking rod 51 can be rod-shaped, or plate-shaped, block-shaped or the like. In other embodiments, the self-locking rod can also be arranged on the mounting plate. When the telescopic cylinder drives the mounting plate to turn over to the first work station, the self-locking rod and the support plate are locked, and the support plate and the mounting plate are also connected and fixed, thereby maintaining the stability of the turnover device in the current work station.

[0039] In one embodiment, the mounting plate 30 is provided with a limiting protrusion 31 at the end away from the support plate 20, and the self-locking rod 51 is provided with a limiting gap 511 at the end away from the support plate 20. When the limiting protrusion 31 is flipped to the first station closest to the self-locking rod 51, the limiting protrusion 31 is clamped in the limiting gap 511. The locking between the self-locking rod 51 and the mounting plate 30 is achieved through the limiting protrusion 31 and the limiting gap 511, so that the mounting plate 30 is stably kept in the flipped station, without the power support of the driving mechanism 40, the power demand of the driving mechanism 40 is reduced, and the cost is saved. In this embodiment, the limiting protrusion 31 adopts a rotating wheel structure. In other embodiments, the limiting protrusion can be provided on the self-locking rod, and the limiting gap can be provided on the mounting plate. When the limiting protrusion is flipped to the first station closest to the self-locking rod, the limiting protrusion is clamped in the limiting gap, which can also achieve the locking of the mounting plate in the first station.

[0040] In one embodiment, when the mounting plate 30 is provided with a plurality of limiting protrusions 31 at the end away from the support plate 20, and the self-locking rod 51 is provided with a plurality of limiting gaps 511, the mounting plate 30 can be flipped by a plurality of angles under the driving of the telescopic cylinder 41. Different limiting gaps 511 cooperate with different self-locking rods 51 to lock the mounting plate 30 in positions other than the first station, so that the flipping device can increase a plurality of stations, and lock the mounting plate 30 with different flipping angles in different stations.

[0041] In one embodiment, the limiting protrusion 31 can be provided with a limiting groove in the middle, or a through hole to form a limiting ring. The end of the self-locking rod 51 away from the first fixed shaft 21 can be protruded to form a locking rod cooperating with the limiting groove / limiting ring. When the mounting plate 30 is rotated to the first station, the locking rod is inserted into the limiting groove / limiting ring under the driving of the telescopic cylinder 41 to achieve the locking of the mounting plate 30. In other embodiments, the self-locking rod 51 and the mounting plate 30 can be respectively provided with a magnet at the end away from the support plate 20. When the dark turning plate is flipped to the first station, the self-locking rod 51 and the mounting plate 30 can be locked by the magnetic attraction of a pair of magnets. In other embodiments, the self-locking rod 51 and the mounting plate 30 can be respectively provided with a pair of hooks, and the self-locking rod 51 and the mounting plate 30 are locked in the first station by clamping a pair of hooks.

[0042] In one embodiment, the overturning device further comprises an unlocking mechanism, the unlocking mechanism comprising an unlocking rod 60 and an unlocking drive, one end of the unlocking rod 60 being connected with the support plate 20, the other end of the unlocking rod 60 being movable under the drive of the unlocking drive, when the unlocking drive drives the unlocking rod 60 to move to an unlocking position, the unlocking rod 60 drives the self-locking rod 51 provided on the support plate 20 to disengage from the mounting plate 30. Specifically, one end of the unlocking rod 60 is rotationally connected with the support plate 20, the other end of the unlocking rod 60 is provided with an unlocking wheel, when the unlocking drive drives the unlocking rod 60 to rotate to the unlocking position, the unlocking wheel lifts the self-locking rod 51 to disengage from the mounting plate 30. In other embodiments, the unlocking rod 60 can also move downward to disengage from the limiting gap 511 by driving the limiting protrusion 31, so as to achieve the unlocking of the mounting plate 30 and the support plate 20. Wherein, the unlocking drive is the driving mechanism 40, the driving end of the driving mechanism 40 is in transmission connection with the unlocking rod 60.

[0043] In one embodiment, the support plate 20 is provided with a first fixed shaft 21 and a second fixed shaft 22. One end of the self-locking rod 51 is rotationally connected with the first fixed shaft 21, the other end of the self-locking rod 51 is used for locking the mounting plate 30. One end of the mounting plate 30 is rotationally connected with the second fixed shaft 22, the other end of the mounting plate 30 is used for locking with the self-locking rod 51. In use, the telescopic cylinder 41 is started, the self-locking rod 51 is driven to rotate around the first fixed shaft 21 by the unlocking rod 60, the self-locking rod 51 is unlocked from the mounting plate 30; the mounting plate 30 is driven to rotate freely around the second fixed shaft 22, so that the overturning device is overturned and changed between two stations.

[0044] When the mounting plate 30 is overturned to the station that needs to be self-locked, the self-locking rod 51 can rotate counterclockwise around the first fixed shaft 21 under the action of gravity, and the mounting plate 30 is locked. At this time, the self-locking rod 51 becomes a connecting piece between the support plate 20 and the mounting plate 30, so that the overturning device can stably stay in this station without the power provided by the driving mechanism 40 to maintain the state of the overturning device.

[0045] In one embodiment, the support plate 20 is provided with a third fixed shaft 23, the third fixed shaft 23 and the second fixed shaft 22 have coaxial centers. The unlocking rod 60 is divided into a tail end, a middle part and a head end along the length direction of the unlocking rod 60, the tail end of the unlocking rod 60 is rotationally connected with the third fixed shaft 23, the middle part of the unlocking rod 60 is provided with a fourth fixed shaft 61, the output end of the telescopic cylinder 41 is rotationally connected with the fourth fixed shaft 61, the head end of the unlocking rod 60 abuts against the self-locking rod 51.

[0046] In use, the telescopic cylinder 41 is started to change in length, the output end of the telescopic cylinder 41 transmits driving force to the unlocking rod 60 through the fourth fixed shaft 61, and drives the unlocking rod 60 to rotate around the third fixed shaft 23, so that the head end of the unlocking rod 60 can provide a pushing force for the self-locking rod 51 through the abutting position of the self-locking rod 51, and drives the self-locking rod 51 to rotate counterclockwise around the first fixed shaft 21 and to be unlocked from the mounting plate 30.

[0047] Further, V-shaped protrusions are arranged at the abutting position of the self-locking rod 51 and the unlocking rod 60, which are used to make the self-locking rod 51 push the unlocking rod 60 from both left and right ends, so that the self-locking rod 51 rotates clockwise around the first fixed shaft 21 by a sufficient angle, so that the mounting plate 30 can be freely flipped. The inward design of the two sides of the V-shaped protrusions can leave enough space for the unlocking rod 60, and when the tip of the middle part of the V-shaped protrusion abuts against the unlocking rod 60, the rotation angle of the self-locking rod 51 is the largest. In other embodiments, the abutting position of the self-locking rod 51 and the unlocking rod 60 can also be arranged in other shapes that are convenient for transmitting the pushing force, such as U-shaped protrusions and the like.

[0048] In one embodiment, the mounting plate 30 is provided with a first limiting piece and a second limiting piece, and the second limiting piece is closer to the support plate 20 than the first limiting piece. When the mounting plate 30 is in the first station, the unlocking rod 60 is rotated to the unlocking position, and the unlocking rod 60 abuts against the first limiting piece. Specifically, a through guide groove 24 is formed on the mounting plate 30 perpendicular to the plate surface, the first limiting piece and the second limiting piece are respectively the left side wall and the right side wall of the guide groove 24, and the fourth fixed shaft 61 passes through the guide groove 24 in the axial direction. When the fourth fixed shaft 61 slides in the guide groove 24 away from the support plate 20, the unlocking rod 60 unlocks the self-locking rod 51 and the mounting plate 30. When the fourth fixed shaft 61 slides to the side wall of the guide groove 24 away from the support plate 20, the telescopic air cylinder 41 provides a force to the mounting plate 30 through the side wall of the guide groove 24 to drive the mounting plate 30 to flip.

[0049] Further, the self-locking mechanism 50 further comprises an elastic reset piece 52, one end of which is fixedly connected to the support plate 20, and the other end is fixedly connected to the self-locking rod 51. The support plate 20 provides an elastic force close to the mounting plate 30 to the self-locking rod 51 through the elastic reset piece 52, the direction of the force exerted by the elastic reset piece 52 on the self-locking rod 51 is opposite to the direction of the force exerted by the unlocking rod 60 on the self-locking rod 51, so that the elastic reset piece 52 keeps the self-locking rod 51 in the fixed position. The elastic reset piece 52 limits the rotation range of the self-locking rod 51, helps the self-locking rod 51 to reset to the position capable of locking the mounting plate 30, and prevents the self-locking rod 51 from over-flipping and losing the locking effect. Among them, the rotation angle of the first fixed shaft 21 is limited, and when the elastic reset piece 52 rotates the self-locking rod 51 to the horizontal position, the first fixed shaft 21 is automatically clamped, so that the elastic reset piece 52 keeps the self-locking rod 51 in the fixed position. In other embodiments, a support protrusion can also be arranged on the support plate 20, so that the self-locking rod 51 is clamped on the support protrusion when it is rotated to the horizontal position, so that the elastic reset piece 52 keeps the self-locking rod 51 in the fixed position.

[0050] When the actual loading and unloading needs to use the second station of the flipping device, the unlocking rod 60 is rotated to the unlocking position, and the telescopic air cylinder 41 is driven to drive the mounting plate 30 to flip to the second station. Figure 2 , 3As shown, the telescopic cylinder 41 starts to work, the output end of the telescopic cylinder 41 is extended, the output end of the telescopic cylinder 41 rotates around the fourth fixed shaft 61, and drives the fourth fixed shaft 61 to slide in the guide groove 24, at the same time, the unlocking lever 60 provided with the fourth fixed shaft 61 rotates around the third fixed shaft 23, the first end of the unlocking lever 60 provides a pushing force for the self-locking lever 51 away from the mounting plate 30 under the drive of the telescopic cylinder 41, drives the self-locking lever 51 to rotate around the first fixed shaft 21, and unlocks the mounting plate 30.

[0051] Then, the telescopic cylinder 41 continues to extend, the fourth fixed shaft 61 abuts against the left inner wall of the guide groove 24, the telescopic cylinder 41 provides a pushing force for the mounting plate 30 through the fourth fixed shaft 61, drives the mounting plate 30 to rotate ninety degrees around the second fixed shaft 22 to the second station, and the unlocking lever 60 also rotates to the left lower end away from the self-locking lever 51 at the same time, the self-locking lever 51 rotates back to the initial position around the first fixed shaft 21 under the pulling force of the elastic reset member 52. At this time, the turnover device is in the second station, and the corresponding loading and unloading process can be completed in this station.

[0052] Subsequently, when the turnover device needs to be turned over to the first station again, as shown in FIG. 5, Figure 4 As shown, the telescopic cylinder 41 only needs to shorten the telescopic end, the unlocking lever 60 rotates to the avoidance position to push the self-locking lever 51 counterclockwise, and the self-locking lever 51 is separated from the fixed position. The output end of the telescopic cylinder 41 rotates around the fourth fixed shaft 61, and drives the fourth fixed shaft 61 to slide to the right in the guide groove 24 and abut against the right inner wall of the guide groove 24, that is, the second limiting member, and the telescopic cylinder 41 drives the mounting plate 30 to rotate to the first station through the second limiting member. At this time, the unlocking lever 60 is rotated to the included angle between the self-locking lever 51 and the supporting plate 20, and there is no interaction force between the unlocking lever 60 and the self-locking lever 51, and the elastic pulling force of the elastic reset member 52 counterclockwise pulls the self-locking lever 51, the limiting protrusion 31 and the limiting notch 511 are clamped, and the mounting plate 30 is locked in the first station by the self-locking lever 51. The elastic reset member 52 is preferably a spring. In other embodiments, the first limiting member and the second limiting member can be a pair of limiting protrusions or limiting cams arranged on the mounting plate 30.

[0053] In one embodiment, the second fixed shaft 22 is a limiting rotation shaft with a rotation angle of ninety degrees, so that the mounting plate 30 will not continue to rotate after rotating around the second fixed shaft 22 from the first station to the second station, avoiding excessive turnover of the mounting plate 30, ensuring the stability of the second station, and improving the safety of the loading and unloading process.

[0054] In other embodiments, a blocking block 32 can be formed on the end of the mounting plate 30 close to the second fixed shaft 22, as shown in FIG. 6. Figure 3As shown, when the mounting plate 30 is rotated from the first station to the second station around the second fixed shaft 22, the blocking block 32 and the supporting plate 20 abut to prevent the mounting plate 30 from being excessively flipped counterclockwise, and the blocking block 32 provides a supporting force for the mounting plate 30 to be kept in the second station, so that the telescopic cylinder 41 does not need to provide a continuous driving force for the mounting plate 30 to be kept in the second station, the requirement for the driving force of the telescopic cylinder 41 is reduced, and the failure rate of the telescopic cylinder 41 is reduced. At this time, since the self-locking rod 51 can provide a self-locking force for the mounting plate in the first station, and the blocking block 32 can provide an abutting action for the mounting plate in the second station. The telescopic cylinder 41 only needs to provide a force for switching the mounting plate between different stations, and does not need to bear a force for keeping the position of the mounting plate unchanged, which greatly reduces the stress load of the telescopic cylinder.

[0055] In an embodiment, the fifth fixed shaft 27 is arranged on the connecting rod 26, the fixed end of the telescopic cylinder 41 is rotationally connected to the fifth fixed shaft 27, and the telescopic end is rotationally connected to the fourth fixed shaft 61. When the telescopic cylinder 41 works, its output end is elongated and rotates around the fourth fixed shaft 61, and its cylinder end rotates around the fifth fixed shaft 27, so that the telescopic cylinder 41 drives the unlocking rod 60 and the mounting plate 30 to rotate, thereby completing the unlocking and flipping of the device. In other embodiments, the driving mechanism 40 can also be a linear motor, a lead screw drive, or the like.

[0056] In an embodiment, a loading and unloading device includes a moving mechanism, a jig plate 10, a taking and placing mechanism, and a flipping device in any of the above embodiments. The moving mechanism is used to move the flipping device, and can be a transport vehicle, a truck, or the like, which is not limited in the present embodiment. The jig plate 10 is arranged on the mounting plate 30, and the taking and placing mechanism is arranged on the jig plate 10. The taking and placing mechanism is used to take and place materials, and can be a suction cup or a gripper. In use, the moving mechanism moves the flipping device to the goods to be loaded and unloaded, the flipping mechanism flips the jig plate 10 to a suitable station, the taking and placing mechanism picks up the goods, and the moving mechanism moves the flipping device, the taking and placing mechanism, and the goods thereon to a unloading area, thereby completing the loading and unloading of the goods.

[0057] In an embodiment, as shown in Figure 5 The loading and unloading device includes a connecting rod 26 and a pair of flipping devices in any of the above embodiments. The pair of supporting plates 20 of the pair of flipping devices are fixedly connected through the connecting rod 26, and the pair of supporting plates 20 cooperate with the connecting rod 26 to provide a stable support for the loading and unloading device. The jig plate 10 is arranged between the adjacent plate surfaces of the pair of mounting plates 30. Compared with arranging the jig plate 10 on one mounting plate 30, the jig plate 10 in the present embodiment is supported by the pair of mounting plates 30, and the flipping of the jig plate 10 with the taking and placing mechanism is more stable and is less likely to slip and fall.

[0058] In one embodiment, another connecting rod 26 is also used to connect the adjacent surfaces of the pair of mounting plates 30. The connecting rod 26 between the mounting plates 30 can strengthen the integrity of the pair of mounting plates 30, drive the pair of mounting plates 30 to move synchronously, avoid the out-of-synchronization between the mounting plates 30 to cause the jig plate 10 to be deformed or even damaged, and reduce the additional cost. In other embodiments, the loading and unloading device can include multiple turnover devices, and the multiple turnover devices can collectively perform the turnover operation on one jig plate 10. The turnover process of the jig plate 10 is more stable, the jig plate 10 can be more accurately turned to the work station, and the loading and unloading of the cargo can be more safely and reliably completed.

[0059] The above description of the embodiments is to facilitate the understanding and application of the technology by those of ordinary skill in the art.
