Description

Technical Field

[0001] The utility model relates to the field of transport clamping, in particular to an anti-pressure basket protection device. Background Art

[0002] During the industrial cleaning and drying process, the cleaning basket needs to be transferred from one station to another. In order to improve the degree of automation, a robot is generally used to transfer the cleaning basket. When using a robot to transfer the cleaning basket, it is necessary to prevent the robot from crushing the cleaning basket.

[0003] Currently, a single-arm manipulator anti-basket pressure protection device with the publication number CN206357279U is disclosed on the market. Two linear bearings are arranged on the manipulator cross arm, and a connecting shaft is slidingly arranged in the linear bearing. A fixed plate is arranged between the two connecting shafts, and a sensor is arranged on the manipulator cross arm. The sensor is aligned with the fixed plate, and a hook basket rack is arranged on the connecting shaft. When the hook basket rack is pressed on the cleaning basket, the manipulator cross arm will continue to move downward, and the hook basket rack and the connecting shaft will no longer move downward after being blocked by the cleaning basket. At this time, the sensor on the manipulator cross arm cannot sense the fixed plate, and it can be determined that there is a basket pressure. However, this device has the following defects: First, when one hook basket rack presses the basket and the other hook basket rack does not, since the two connecting shafts are rigidly connected by a fixed plate, the two connecting shafts will interfere with the linear bearings due to pulling, which not only affects the operation of the manipulator, but also easily causes wear between the linear bearings and the connecting shafts. Secondly, since the distance between the two hook basket racks is fixed, it is more likely to press the basket when hoisting the cleaning basket. Utility Model Content

[0004] The utility model aims to provide an anti-basket pressure protection device which can effectively prevent the occurrence of basket pressure and will not cause damage to the linear bearing and the slide rod when the basket is pressed due to operating errors by staff.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an anti-pressure basket protection device, comprising: a mounting plate that can be connected to a manipulator, a slide groove is provided in the mounting plate, a sliding card is provided with two slides in the slide groove, racks are provided on both slides, a machine base is provided on the mounting plate, a self-locking reduction motor is provided on the machine base, a gear is provided on the self-locking reduction motor, the gear extends into the slide groove and meshes with the two racks, the two racks are respectively located on the front and rear sides of the gear, a linear bearing is provided in the slide, a sliding rod is provided on the sliding card in the linear bearing, a hook is provided at the lower end of the slide rod, an induction plate is provided at the upper end of the slide rod, a proximity switch is provided on the slide, and the sensing end of the proximity switch faces the induction plate.

[0015] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0016] like Figures 1 to 3 As shown, the anti-pressure basket protection device of the present invention includes: a mounting plate 1 that can be connected to a manipulator, a slide groove 11 is provided in the mounting plate 1, and guide rails 12 are provided on the front and rear side walls of the slide groove 11. Two slides 2 are provided in the slide groove 11, and the slides 2 rest on the two guide rails 12 at the same time. A rack 21 and a limit plate 22 are provided on the two slides 2. The rack 21 on the slide 2 rests on the guide rail 12 on the corresponding side, and the limit plate 22 on one slide 2 rests on the other slide 2, the top walls of the two limit plates 22 are flush with the top wall of the mounting plate 1, and a motor seat 3 is provided on the top wall of the mounting plate 1. The motor seat 3 is against the two limit plates 22 at the same time. A self-locking reduction motor 31 is provided on the motor seat 3. The motor seat 3 cooperates with the guide rail 12 to limit the stacked racks 21 and the limit plates 22. While improving the stability of the two slides 2, it will not interfere with the slide 2. A gear 32 is provided on the self-locking reduction motor 31, and the gear 32 extends into The slide 11 is meshed with two racks 21, and the two racks 21 are respectively located on the front and rear sides of the gear 32. The upper and lower thicknesses of the gear 32 are greater than the upper and lower thicknesses of the rack 21, thereby ensuring the gear transmission effect of the gear 32 on the two racks 21. The front and rear widths of the limit plate 22 and the guide rail 12 are less than the tooth bottom width of the rack 21 to prevent the gear 32 from interfering with the limit plate 22 and the guide rail 12. A linear bearing 4 is provided in the slide 2, and a slide rod 5 is slidably provided in the linear bearing 4. A boss 5 is provided on the slide rod 5. 1, the boss 51 rests on the linear bearing 4, a lower flat groove is provided on the side wall of the lower end of the slide bar 5, a hook 6 is fixed in the lower flat groove by bolts, the top of the hook 6 rests on the top inner wall of the lower flat groove, thereby improving the connection strength and stability between the hook 6 and the slide bar 5, an upper flat groove is provided on the side wall of the upper end of the slide bar 5, a sensing plate 52 is fixed in the upper flat groove by bolts, a support plate 23 is provided on the slide seat 2, a proximity switch 24 is provided on the support plate 23, and the sensing end of the proximity switch 24 faces the sensing plate 52.

[0017] When in use, the mounting plate 1 is moved to the top of the cleaning basket by the manipulator, and then the self-locking reduction motor 31 drives the gear 32 to rotate. The rotating gear 32 drives the two slides 2 to move in reverse through the gear transmission between the two racks 21, so that the spacing between the two hooks 6 is greater than the width of the cleaning basket to be hoisted. Then the manipulator drives the mounting plate 1 to descend. Since the spacing between the two hooks 6 is greater than the width of the cleaning basket, the hooks 6 will not cause pressure on the cleaning basket during the descending process. Then the self-locking reduction motor 31 is started to drive the gear 32 to rotate in the opposite direction, so that the two slides 2 move in opposite directions until the two hooks 6 respectively rest on the two side walls of the cleaning basket. At this time, the hooks 6 cooperate with the shaft-type lifting ears on the side walls of the cleaning basket, and the manipulator drives the mounting plate 1 to move upward, and the hooks 6 can hook the shaft-type lifting ears on the same side to lift the cleaning basket. This can prevent the hooks 6 from being pressed against the cleaning basket, and the spacing between the two hooks 6 can be adjusted to accommodate cleaning baskets of different specifications.

[0018] When the distance between the hooks 6 is not adjusted properly, resulting in a basket compression between the hooks 6 and the cleaning basket, each hook 6 is detected separately, that is, when a basket compression occurs on a certain hook 6, the slide rod 5 connected to the hook 6 will move upward with the sensing plate 52, and the proximity switch 24 on the slide 2 will not be able to sense the sensing plate 52. The manipulator receives the signal and determines that the basket is compressed and stops the action. There is no connecting part for rigid connection between the slide rods 5. When a certain slide rod 5 rises in the linear bearing 4 due to the basket compression, the other slide rods 5 will not be affected, and there will be no wear between the linear bearing and the connecting shaft due to the rigid connection between the connecting shafts as in the single-arm manipulator anti-basket compression protection device with publication number CN206357279U.
