[0002] Palletizing robots are a product of the organic combination of mechanics and computer programs. They provide higher production efficiency for modern manufacturing and are widely used in the palletizing industry. Palletizing robots greatly save labor and space. They are flexible, precise, fast, efficient, and highly stable, resulting in high operating efficiency. Therefore, limit guide rail devices are frequently used in the operation of palletizing robots.

[0003] During the long-term operation of palletizing robots, dust, material debris and other contaminants easily accumulate on the surface of the limit guide rail. These impurities directly affect the matching accuracy between the guide rail and the slider, resulting in increased motion resistance, increased wear of components, and making it difficult to clean and maintain the guide rail device. Utility Model Content

[0004] The purpose of this utility model is to provide a limiting guide rail device for a palletizing robot, so as to solve the problems mentioned in the background art, where the limiting guide rail of a palletizing robot is prone to accumulating dust, material debris and other contaminants during long-term operation, which affects the fitting accuracy, increases resistance, accelerates wear, and is inconvenient to clean and maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting guide rail device for a palletizing robot, comprising a base plate, a track fixedly provided at the top of the base plate, limiting plates slidably provided on both sides of the track, a lead screw rotatably provided between the two limiting plates, a slider threadedly connected to the surface of the lead screw via a lead screw nut, support boxes provided on both sides of the top of the base plate, a threaded rod threadedly connected to the inside of the support box via a limiting nut, a support block rotatably provided at one end of the threaded rod, an insert plate fixedly provided on one side of the support block for insertion and connection with the limiting plate, an mounting plate fixedly provided at the top of the slider, and mounting components provided on both sides of the top of the mounting plate.

[0007] As a preferred technical solution of this utility model, a forward and reverse motor is fixedly provided on one side of one of the limiting plates, and the output shaft of the forward and reverse motor passes through the limiting plate and is fixedly connected to one end of the lead screw.

[0008] As a preferred technical solution of this utility model, the slider is slidably connected to the track, and two limiting rods are symmetrically slidably provided in the middle of the slider, with both ends of the limiting rods being fixedly connected to the surface of the limiting plate.

[0009] As a preferred embodiment of this utility model, the support block and the support box are slidably connected, and an adjusting cap is fixedly provided at the other end of the threaded rod.

[0010] As a preferred technical solution of this utility model, the installation component includes two limiting blocks, which are symmetrically slidably disposed at the top of the installation plate. A side plate is fixedly provided at the top of the limiting blocks, and four evenly spaced through holes are opened on the surface of the side plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a limiting guide rail device for a palletizing robot, including a base plate 1, a track 2 fixedly mounted on the top of the base plate 1, limiting plates 3 slidably mounted on both sides of the track 2, a lead screw 4 rotatably mounted between the two limiting plates 3, and a slider 5 threadedly connected to the surface of the lead screw 4 via a lead screw nut. Support boxes 6 are provided on both sides of the top of the base plate 1, and threaded rods 7 inside the support boxes 6 are threadedly connected to the limiting nuts. Rotating the threaded rods 7 can push support blocks 8 to move, causing the insert plate 9 on one side of the support block 8 to insert into the limiting plate 3, thereby quickly fixing the position of the limiting plate 3, preventing the limiting plate 3 from shifting during device operation, and improving structural stability. The support boxes 6 have threaded rods 7 threadedly connected to the inside via limiting nuts, and one end of the threaded rod 7 is rotatably mounted with a support block 8. A plug plate 9 is fixedly provided on one side of the support block 8 and is inserted into the limiting plate 3. The rotation of the threaded rod 7 drives the support block 8 inside the support box 6 to move, so that the plug plate 9 at the support block 8 moves at the same time. By separating the plug plate 9 from the limiting plate 3, the limiting plate 3, the lead screw 4 and the slider 5 can be disassembled and separated from the track 2, which facilitates the subsequent cleaning and maintenance of the track 2. A mounting plate 11 is fixedly provided at the top of the slider 5, and mounting components 12 are provided on both sides of the top of the mounting plate 11. The mounting plate 11 and the mounting components 12 at the top provide a convenient installation interface for the palletizing robot base. At the same time, the spacing can be adjusted according to the installation size of the robot base to adapt to the installation of robot bases of different specifications, thereby improving the adaptability of the mounting components 12.

[0025] The slider 5 is slidably connected to the track 2. Two limiting rods 14 are symmetrically slidably provided in the middle of the slider 5. Both ends of the limiting rods 14 are fixedly connected to the surface of the limiting plate 3. The sliding connection between the slider 5 and the track 2 allows the slider 5 to slide without restriction. The two limiting rods 14 symmetrically slidably provided in the middle of the slider 5 can strictly limit the sliding range of the slider 5, prevent the slider 5 from slipping off the track 2 due to excessive sliding, avoid the slider 5 from shaking, and ensure the smooth operation of the palletizing robot.

[0026] One of the limiting plates 3 is fixedly equipped with a forward and reverse motor 10. The output shaft of the forward and reverse motor 10 passes through the limiting plate 3 and is fixedly connected to one end of the lead screw 4. The forward and reverse motor 10 provides a power source for the rotation of the lead screw 4, realizing the automated control of the movement of the slider 5. The forward and reverse motor 10 can realize forward and reverse rotation, thereby driving the lead screw 4 to rotate in the forward and reverse directions, so that the slider 5 can realize reciprocating linear motion, meeting the material handling needs of the palletizing robot between different workstations.

[0027] Mounting assembly 12 includes two limiting blocks 1201, which are symmetrically slidably disposed at the top of mounting plate 11. A side plate 1202 is fixedly disposed at the top of each limiting block 1201. Four evenly spaced through holes 1205 are formed on the surface of the side plate 1202, and a protective pad is fixedly disposed on the surface of the side plate 1202. Two mounting blocks 1203 are symmetrically fixedly disposed at the bottom of one side of the side plate 1202. A bolt 1204 is threadedly connected to the center of each mounting block 1203. Several screw holes 1204 are threadedly connected to the bolts 1204 at the top of the mounting plate 11. A limiting groove 13, which moves and engages with the limiting blocks 1201, is formed at the center of the top of the mounting plate 11. The spacing between the two symmetrically slidably disposed limiting blocks 1201 at the top of the mounting plate 11 in mounting assembly 12 can be adjusted according to the installation dimensions of the robot base to adapt to different sizes. The installation of robot bases of different specifications improves the adaptability of the mounting component 12; four evenly spaced through holes 1205 on the surface of the side plate 1202 at the top of the limiting block 1201 facilitate further fixing of the robot base with bolts and other connectors, enhancing the stability of the robot after installation; the protective pad on the surface of the side plate 1202 can protect the robot base when it comes into contact with the side plate 1202, preventing wear caused by rigid contact between the robot and the side plate 1202; two mounting blocks 1203 symmetrically fixed at the bottom of one side of the side plate 1202 can quickly lock the position of the limiting block 1201 by engaging with the screw hole at the top of the mounting plate 11 through the central threaded bolt 1204; the limiting groove 13 at the top center of the mounting plate 11, which moves and engages with the limiting block 1201, provides guidance for the sliding of the limiting block 1201.

[0028] The support block 8 and the support box 6 are slidably connected, and the other end of the threaded rod 7 is fixedly provided with an adjusting cap 15. The sliding connection between the support block 8 and the support box 6 makes the support block 8 play a limiting role, ensuring that the support block 8 can move in a straight line under the push of the threaded rod 7, so that the insert plate 9 can be accurately inserted into the limiting plate 3. The adjusting cap 15 fixed at the other end of the threaded rod 7 increases the contact area between the hand and the threaded rod 7, making it easier for the operator to manually rotate the threaded rod 7.

[0029] The base plate 1 has several evenly spaced mounting holes 19 on its surface. The track 2 has several evenly spaced reinforcing plates 18 fixed on both sides, with the bottom end of the reinforcing plates 18 fixedly connected to the top end of the base plate 1. The several evenly spaced mounting holes 19 on the surface of the base plate 1 facilitate fixing the entire limiting guide rail device to the ground via connectors, improving the stability and convenience of the device installation. The several evenly spaced reinforcing plates 18 fixed on both sides of the track 2, with their bottom ends fixedly connected to the top end of the base plate 1, can enhance the connection strength between the track 2 and the base plate 1, preventing the track 2 from deforming or loosening under long-term load of the slider 5 and the robot's weight, extending the service life of the track 2, and ensuring the overall stability of the device operation.

[0030] The surface of the support box 6 is provided with four evenly spaced fixing plates 16. The middle of the fixing plate 16 is threaded with a bolt 17. The top of the base plate 1 is provided with a screw hole 2 that is threaded to the bolt 17. The four evenly spaced fixing plates 16 on the top of the surface of the support box 6 can be firmly fixed to the base plate 1 by the bolt 17 threaded in the middle and the screw hole 2 at the top of the base plate 1, so as to prevent the support box 6 from being displaced during the rotation of the threaded rod 7 or the operation of the device.

[0031] When using it, first select a flat installation area (such as the ground or a frame platform) required for the palletizing robot operation, place the base plate 1 flat in the installation position, and align the several evenly spaced mounting holes 19 on the surface of the base plate 1 with the preset holes on the installation base. Then, use bolts, expansion screws and other compatible connectors to firmly fix the base plate 1 to the installation base through the mounting holes 19, ensuring that the base plate 1 is not loose or offset, and providing a stable foundation for the subsequent installation of components.

[0032] Next, the two limiting plates 3 are slidably installed on both sides of the track 2, so that the lead screw 4 and the slider 5 are installed at the track 2. Then, hold the adjusting cap 15 and rotate the threaded rod 7 clockwise. Since the threaded rod 7 is threadedly connected to the limiting nut inside the support box 6, the threaded rod 7 will push the support block 8 to slide along the inside of the support box 6 during the rotation until the insert plate 9 on one side of the support block 8 is fully inserted into the corresponding slot of the limiting plate 3, so as to quickly fix the limiting plate 3 and prevent the limiting plate 3 from shifting when the device is running. Then, turn on the power of the forward and reverse motor 10 and test the forward and reverse functions of the motor through the motor controller: when the motor rotates forward, it drives the lead screw 4 to rotate clockwise, and the slider 5 on the surface of the lead screw 4 (threadedly connected to the lead screw 4 through the lead screw nut) moves along the track 2 towards the limiting plate 3; when the motor rotates in reverse, the slider 5 should move towards the other limiting plate 3 to ensure that the transmission between the lead screw 4 and the slider 5 is smooth and without jamming.

[0033] According to the size specifications of the palletizing robot base, push the two limiting blocks 1201 at the top of the mounting plate 11 to slide along the limiting groove 13 in the middle of the mounting plate 11 until the side plates 1202 at the top of the two limiting blocks 1201 are in contact with the two sides of the robot base. Pass the bolt 1204 through the threaded hole in the middle of the mounting block 1203 at the bottom of the side plate 1202, align it with the corresponding threaded hole at the top of the mounting plate 11 and tighten it to lock the position of the limiting blocks 1201. Then, through the four evenly spaced through holes 1205 on the surface of the side plate 1202, use additional bolts to further fix the robot base to the side plate 1202 to enhance the stability of the robot base after installation and prevent the base from shaking during operation. Then, the device can be tested under no-load conditions.

[0034] When dust, material debris, and other contaminants accumulate on the surface of track 2, affecting the sliding accuracy of slider 5, cleaning and maintenance are required: Hold the adjusting cap 15 and rotate the threaded rod 7 counterclockwise, causing the threaded rod 7 to drive the support block 8 to slide in the opposite direction, and the insert plate 9 to separate from the slot of the limiting plate 3; then slide the two limiting plates 3 along track 2 to remove them, and at the same time disassemble the connection between the limiting rod 14 and the limiting plate 3, so that the lead screw 4, slider 5 and track 2 can be separated. Use a brush or neutral detergent to thoroughly clean the contaminants on the surface of track 2; at the same time, check the wear of the lead screw nut inside slider 5 and the surface of the limiting rod 14. If there is excessive wear, it needs to be replaced in time; after cleaning, reassemble the components in reverse order to ensure that all connections are stable, and then conduct a no-load test run to confirm that the device has returned to normal operation.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
