Description

Technical Field

[0001] This invention relates to the field of AGV positioning technology, and more specifically to a deviation correction device. Background Technology

[0002] The correction device is designed to eliminate the impact of AGV positioning and rack installation errors on normal docking and power transmission.

[0003] Chinese Patent No. CN212556587U discloses a correction device for AGV (Automated Guided Vehicle) trolleys. The correction device for AGV trolleys includes a connecting frame, a bracket, a mounting plate, a connecting shaft, and a lifting mechanism. The bracket has drive wheels and drive parts for driving the drive wheels on both sides. The connecting shaft passes through the connecting frame and is slidably connected to the connecting frame. The lower end of the connecting shaft is connected to the bracket, and the upper end of the connecting shaft is fixedly connected to a correction cam.

[0004] However, the correction device used for AGVs requires the cam bearing located at the eccentric part of the cam to rotate along the cam, thereby driving the correction cam to move upward and driving the connecting shaft to slide upward along the connecting frame. This results in a single correction direction and poor effect, which in turn affects the correction effect of the AGV and needs to be improved. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a correction device that solves the problem of poor correction effect of AGV trolley.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A deviation correction device includes a connector for connecting to an AGV (Automated Guided Vehicle) on-board power connector and a connecting rod fixedly connected to the connector. A deviation correction connecting unit is sleeved on the connecting rod. The deviation correction connecting unit is sequentially connected to a lifting deviation correction unit and a lateral deviation correction unit. The lateral deviation correction unit is connected to a floating base plate and only performs lateral movement relative to the floating base plate. The lifting deviation correction unit only performs lifting movement relative to the deviation correction connecting unit. The lifting deviation correction unit includes a lifting reset component for resetting the lifting deviation correction unit to a set height. The lateral deviation correction unit includes a lateral reset component for resetting the lateral deviation correction unit to a set coordinate position.

[0008] By adopting the above technical solution, if an installation error requiring correction occurs when the AGV vehicle-mounted power connector is connected to the connector head, the error will be effectively corrected through the lifting correction unit and the lateral correction unit via the connecting rod. The lifting reset component and the lateral reset component provide support, so that the correction device has the effect of strong displacement compensation capability in all directions, compact structure, and large coaxiality tolerance, and can transmit power normally even when the correction connection unit is offset by 15mm in any direction along the circumference.

[0009] The present invention is further configured such that: both ends of the connector are respectively provided with a mating seat and a plug slot, the mating seat is used to connect with the AGV vehicle-mounted power connector, and one end of the connecting rod is provided with a connecting plug portion that is inserted into and fixed in the plug slot.

[0010] By adopting the above technical solution, the docking seat is connected to the AGV vehicle-mounted power docking head, improving the connection stability and accuracy. The insertion slot and the connecting rod are matched and fixed, thereby effectively improving the connection and fixing stability of the connector and the connecting rod.

[0011] The present invention is further configured such that: the correction connection unit includes a floating seat connecting plate, and the floating seat connecting plate has a cover plate groove and a slider groove respectively provided on both sides; a floating seat cover plate is provided in the cover plate groove; the floating seat cover plate has a cover plate through hole; the connecting rod is sleeved with a deep groove ball bearing that matches the cover plate through hole; and the floating seat connecting plate has a connecting plate through hole corresponding to the position of the cover plate through hole and allowing the connecting rod to pass through; the slider groove is used to install and fix the lifting correction unit.

[0012] By adopting the above technical solution, the cover plate groove and the floating seat cover plate are matched and fixed, which improves the installation and fixing stability of the floating seat cover plate and the cover plate groove. After being sleeved on the connecting rod by a deep groove ball bearing, it is then installed into the through hole of the connecting plate, which improves the connection stability between the connecting rod and the correction connection unit. Thus, the correction device solves the problem of poor correction effect of AGV trolley.

[0013] The present invention is further configured such that: the lifting and correcting unit includes a lifting limit guide rail slider and a lifting limit guide rail that are installed and fixed to the correcting connection unit; the lifting limit guide rail slider is provided with a lifting slider groove on the side away from the correcting connection unit; the lifting slider groove matches the lifting limit guide rail and allows the lifting limit guide rail to be inserted for reciprocating movement.

[0014] By adopting the above technical solution, when an installation error in the height direction that needs to be corrected occurs, the slider of the lifting limit guide rail moves vertically up and down under the limit of the lifting limit guide rail, thereby achieving an effective correction effect.

[0015] The present invention is further configured such that: the lateral correction unit includes a correction connecting plate, the correction connecting plate is inverted T-shaped, and is composed of a fixed upper part at the upper end and a fixed lower part at the lower end; the fixed upper part is provided with a limiting connection vertical groove on the side facing the lifting correction unit, the limiting connection vertical groove is matched and fixed with the lifting limiting guide rail, and the fixed lower part is provided with a limiting connection horizontal groove on the side away from the lifting correction unit.

[0016] By adopting the above technical solution, the correction connecting plate effectively connects the lifting correction unit and the lateral correction unit, thereby further improving the correction effect of the correction device.

[0017] The present invention is further configured such that: the lifting and resetting component includes a vertical spring base installed and fixed on the fixed lower part near the lifting and correcting unit; the upper side of the vertical spring base is provided with a vertical limiting spring groove and a vertical spring socket is connected and fixed thereto; the vertical spring socket is provided with a vertical socket through hole communicating with the vertical limiting spring groove; the upper inner diameter of the vertical socket through hole is smaller than the lower inner diameter, and a vertical spring pin is provided with a lower end matching the lower inner diameter of the vertical socket through hole and an upper end matching the upper inner diameter of the vertical socket through hole; a vertical spring is provided between the vertical spring pin and the vertical spring base; the upper end of the vertical spring pin passes through the upper end of the vertical socket through hole and abuts against the lower end of the correcting connection unit.

[0018] By adopting the above technical solution, when the slider of the lifting limit guide rail moves vertically upward and downward under the limit of the lifting limit guide rail due to the installation error in the height direction that needs to be corrected, the vertical spring pin is always in contact with the lower end of the correction connection unit under the action of the vertical spring. When the lifting limit guide rail rises, the length of the vertical spring is stretched and the spring restoring force gradually decreases, thus reducing the contact force on the lower end of the correction connection unit; when the lifting limit guide rail falls, the length of the vertical spring is compressed and the spring restoring force gradually increases, thus increasing the contact force on the lower end of the correction connection unit.

[0019] The present invention is further configured such that: the lateral shift correction unit further includes a lateral shift limiting guide rail that is matched and fixed with the limiting connection transverse groove and a lateral shift limiting guide rail slider that is matched and connected with the lateral shift limiting guide rail, the lateral shift limiting guide rail slider is provided with a lateral shift slider groove that matches the lateral shift limiting guide rail, and the lateral shift limiting guide rail slider is mounted and fixed on the floating seat base plate.

[0020] By adopting the above technical solution, when a horizontal installation error that needs to be corrected occurs, the slider of the transverse limit guide rail moves horizontally under the limit of the transverse limit guide rail, thereby achieving an effective correction effect.

[0021] The present invention is further configured such that: a floating seat upright plate is provided on the upper side of the floating seat base plate, and the transverse movement limiting guide rail slider and the transverse movement reset component are both installed and fixed on the floating seat upright plate.

[0022] By adopting the above technical solution, the floating seat plate effectively connects the transverse movement limit guide rail slider and the transverse movement reset component, thereby enabling the correction device to achieve structural stability and significantly improve the correction effect.

[0023] The present invention is further configured such that: the transverse resetting member includes a horizontal spring seat that is connected and fixed to the floating seat plate; the horizontal spring seat is provided with a horizontal through hole; a horizontal spring pin is inserted into each end of the horizontal through hole, with one end protruding from the corresponding end of the horizontal through hole and the other end moving within the horizontal through hole; and a horizontal spring is provided between the two horizontal spring pins and located within the horizontal through hole.

[0024] By adopting the above technical solution, when the horizontal spring pin is forced to move into the horizontal spring seat, the horizontal spring is compressed, and the resulting elastic restoring force will push the horizontal spring pin to move outward at the corresponding end, so as to achieve effective reset and correction.

[0025] The present invention is further configured such that: two symmetrical protrusions along the length direction are provided on the lower side of the fixed lower part, and a spacer cavity is formed between the two protrusions; the horizontal spring seat is inserted into the spacer cavity, and the two horizontal spring pins abut against the corresponding protrusions respectively.

[0026] By adopting the above technical solution, when the slider of the transverse limiting guide rail moves horizontally under the limitation of the transverse limiting guide rail due to the horizontal installation error that needs to be corrected, the horizontal spring pin is always in contact with the lower end of the correction connection unit under the action of the horizontal spring. When the transverse limiting guide rail moves to one end, the corresponding horizontal spring pin moves, so that the reaction force generated by the horizontal spring acts on both horizontal spring pins at the same time, thereby achieving effective reset and correction effect.

[0027] In summary, the present invention has the following beneficial effects: after being connected by a connector and a connecting rod, a correction connection unit is sleeved on the connecting rod. When the correction connection unit is connected to the lifting correction unit and the lateral correction unit in sequence, the lifting correction unit and the lateral correction unit can transmit power normally to the correction connection unit even when it is offset by 15mm in any direction along the circumference. This solves the problem of poor correction effect of AGV trolley and has the effects of strong displacement compensation capability in all directions, compact structure, and large coaxiality tolerance.

[0031] To make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figure 1 As shown, a deviation correction device includes a connector 1 for connecting to an AGV (Automated Guided Vehicle) on-board power connector and a connecting rod 2 fixedly connected to the connector 1. The connecting rod 2 is sleeved with a deviation correction connecting unit 3, which is sequentially connected to a lifting deviation correction unit 4 and a lateral deviation correction unit 5, enabling the lifting deviation correction unit 4 and the lateral deviation correction unit 5 to achieve effective deviation correction.

[0033] It should be noted that, as Figure 1 , Figure 2As shown, the lateral correction unit 5 is connected to the floating base plate 6 and only moves laterally relative to the floating base plate 6. The lifting correction unit 4 only moves vertically relative to the correction connection unit 3. Simultaneously, the lifting correction unit 4 includes a lifting reset component, which is used to reset the lifting correction unit 4 to a set height. The lateral correction unit 5 includes a lateral reset component, which is used to reset the lateral correction unit 5 to a set coordinate position. Therefore, if an installation error requiring correction occurs when the AGV vehicle-mounted power connector is connected to the connector 1, the error will be effectively corrected through the lifting correction unit 4 and the lateral correction unit 5 via the connecting rod 2. The lifting reset component and the lateral reset component provide support, enabling the correction device to have strong all-directional displacement compensation capability, compact structure, and large coaxiality tolerance, and to achieve normal power transmission even when the correction connection unit 3 is offset by 15mm in any circumferential direction.

[0034] like Figure 2 As shown, a docking seat 11 and a plug-in slot 12 are respectively provided at both ends of the connector 1. The docking seat 11 is used to connect with the AGV vehicle-mounted power connector. One end of the connecting rod 2 is provided with a connecting plug 21 that is inserted into and fixed in the plug-in slot 12. This improves the connection stability and accuracy when the docking seat 11 is connected to the AGV vehicle-mounted power connector. When the plug-in slot 12 and the connecting plug 21 of the connecting rod 2 are matched and fixed, the connection and fixing stability between the connector 1 and the connecting rod 2 is effectively improved.

[0035] It should be noted that the correction connection unit 3 includes a floating seat connecting plate 31. The floating seat connecting plate 31 has staggered cover plate grooves 311 and slider grooves 312 on both sides. A floating seat cover plate 32 is installed within the cover plate groove 311, and the floating seat cover plate 32 has a cover plate through hole 321. Correspondingly, the connecting rod 2 is sleeved with a deep groove ball bearing 33 that matches the cover plate through hole 321, and the floating seat connecting plate 31 has a connecting plate through hole 313 corresponding to the position of the cover plate through hole 321, allowing the connecting rod 2 to pass through. The slider groove 312 is used to install and fix the lifting correction unit 4. Therefore, by matching and fixing the cover plate groove 311 with the floating seat cover plate 32, the installation and fixing stability of the floating seat cover plate 32 with the cover plate groove 311 is improved. After the deep groove ball bearing 33 is sleeved on the connecting rod 2, it is then installed into the connecting plate through hole 313, thereby improving the connection stability between the connecting rod 2 and the correction connection unit 3. This allows the correction device to solve the problem of poor correction effect of the AGV trolley.

[0036] The lifting and correction unit 4 includes a lifting limit guide rail slider 41 and a lifting limit guide rail 42, which are fixedly installed with the correction connection unit 3. The lifting limit guide rail slider 41 has a lifting slider groove 411 on the side away from the correction connection unit 3, and the lifting slider groove 411 matches the lifting limit guide rail 42, allowing the lifting limit guide rail 42 to insert and reciprocate. Therefore, when a height-direction installation error requiring correction occurs, the lifting limit guide rail slider 41 moves vertically upwards and downwards under the limitation of the lifting limit guide rail 42, thereby achieving an effective correction effect.

[0037] The lateral correction unit 5 includes a correction connecting plate 51, a lateral correction guide rail 52 that is fixed to and matched with a limiting connecting transverse groove 5121, and a lateral correction guide rail slider 56 that is fixed to and matched with the lateral correction guide rail 52. The correction connecting plate 51 is inverted T-shaped and consists of a fixed upper part 511 at the upper end and a fixed lower part 512 at the lower end. The fixed upper part 511 has a limiting connecting vertical groove 5111 on the side facing the lifting correction unit 4, and the limiting connecting vertical groove 5111 is fixed to and matched with the lifting correction guide rail 42. The fixed lower part 512 has a limiting connecting transverse groove 5121 on the side facing away from the lifting correction unit 4, so that the correction connecting plate 51 can effectively connect the lifting correction unit 4 and the lateral correction unit 5, thereby further improving the correction effect of the correction device. The transverse limit guide slider 56 is provided with a transverse slider groove 561 that matches the transverse limit guide rail 52, and the transverse limit guide slider 56 is installed and fixed on the floating seat base plate 6. Thus, when a horizontal installation error that needs to be corrected occurs, the transverse limit guide slider 56 moves horizontally in the horizontal direction under the limit of the transverse limit guide rail 52, thereby achieving an effective correction effect.

[0038] like Figure 2As shown, the lifting and resetting component includes a vertical spring base 43 installed and fixed on the side of the fixed lower part 512 near the lifting and correcting unit 4. A vertical limiting spring groove 431 is provided on the upper side of the vertical spring base 43, and a vertical spring socket 45 is connected and fixed thereto. A vertical socket through hole 451 communicating with the vertical limiting spring groove 431 is provided inside the vertical spring socket 45. The upper inner diameter of the vertical socket through hole 451 is smaller than the lower inner diameter, and a vertical spring pin 46 is provided with its lower end matching the lower inner diameter of the vertical socket through hole 451 and its upper end matching the upper inner diameter of the vertical socket through hole 451. The upper end of the vertical spring pin 46 protrudes from the upper end of the vertical socket through hole 451 and abuts against the lower end of the correcting connection unit 3, so that the upper end of the vertical spring pin 46 protrudes from the vertical socket through hole 451 and abuts against the lower end of the correcting connection unit 3, while the lower end is inserted into the vertical socket through hole 451 and moves within it. Meanwhile, a vertical spring 44 is provided between the vertical spring pin 46 and the vertical spring base 43. Therefore, when the lifting limit guide rail slider 41 moves vertically under the limit of the lifting limit guide rail 42 due to the installation error in the height direction that needs to be corrected, the vertical spring pin 46 is always in contact with the lower end of the correction connection unit 3 under the action of the vertical spring 44. When the lifting limit guide rail 42 rises, the length of the vertical spring 44 is stretched, and the spring restoring force gradually decreases, thus reducing the contact force on the lower end of the correction connection unit 3. When the lifting limit guide rail 42 falls, the length of the vertical spring 44 is compressed, and the spring restoring force gradually increases, thus increasing the contact force on the lower end of the correction connection unit 3.

[0039] like Figure 1 , Figure 2As shown, a floating seat upright plate 61 is provided on the upper side of the floating seat base plate 6. The transverse movement limiting guide slider 56 and the transverse movement reset component are both mounted and fixed on the floating seat upright plate 61, thereby enabling the floating seat upright plate 61 to effectively connect the transverse movement limiting guide slider 56 and the transverse movement reset component, thus ensuring the structural stability of the correction device and significantly improving the correction effect. It should be noted that the transverse movement reset component includes a horizontal spring seat 53 connected and fixed to the floating seat upright plate 61. The horizontal spring seat 53 is provided with a horizontal through hole 531, and a horizontal spring pin 54 is inserted into both ends of the horizontal through hole 531, with one end protruding from the corresponding end of the horizontal through hole 531 and the other end moving within the horizontal through hole 531. A horizontal spring 55 is disposed between the two horizontal spring pins 54 and located within the horizontal through hole 531. When the horizontal spring pin 54 is subjected to force and moves into the horizontal spring seat 53, the horizontal spring 55 is compressed, and the resulting elastic restoring force pushes the horizontal spring pin 54 to move outward at the corresponding end, thereby achieving effective reset and correction. At the same time, two symmetrical protrusions 5122 are provided on the lower side of the fixed lower part 512, and a spacer cavity 5123 is formed between the two protrusions 5122. The horizontal spring seat 53 is inserted into the spacer cavity 5123, and the two horizontal spring pins 54 abut against the corresponding protrusions 5122 respectively. Therefore, when the slider 56 of the transverse limiting guide rail moves horizontally under the limitation of the transverse limiting guide rail 52 due to the horizontal installation error that needs to be corrected, the horizontal spring pin 54 is always in contact with the lower end of the correction connection unit 3 under the action of the horizontal spring 55. When the transverse limiting guide rail 52 moves to one end, the corresponding horizontal spring pin 54 moves, so that the reaction force generated by the horizontal spring 55 acts on both horizontal spring pins 54 at the same time, thereby achieving effective reset and correction effect.

[0040] In summary, this application connects the connector 1 and the connecting rod 2, then attaches the correction connection unit 3 to the connecting rod 2. When the correction connection unit 3 is connected to the lifting correction unit 4 and the lateral correction unit 5 in sequence, the lifting correction unit 4 and the lateral correction unit 5 can transmit power normally to the correction connection unit 3 even when it is offset by 15mm in any direction along the circumference. This solves the problem of poor correction effect of the AGV trolley and has the effects of strong displacement compensation capability in all directions, compact structure, and large coaxiality tolerance.
