Description

Technical Field

[0001] The utility model relates to the field of goods picking and placing devices, in particular to a single-motor goods picking and placing mechanism. Background Art

[0002] In the fields of modern industrial production and logistics warehousing, the efficient and accurate picking and placing of goods are key links to achieve automated operations and improve production efficiency. Traditional goods picking and placing operations usually rely on manual labor. However, with the continuous expansion of production scale and the rapid growth of logistics business volume, the manual picking and placing method gradually exposes problems such as low efficiency, high labor intensity, easy errors, and high costs. To improve the efficiency and accuracy of goods picking and placing, automated picking and placing mechanisms have emerged. The early picking and placing mechanisms had relatively simple structures and single functions, such as the common form of a simple robotic arm with a suction cup or a gripper.

[0003] The picking, placing, and moving of coins also belong to the field of goods picking and placing. In the prior art, the picking and placing mechanism can clamp and move the coins through the clamping part. However, sometimes it is necessary to mark both sides of the coins. After marking one side of the coin, it is necessary to flip the whole coin to mark the other side. The flipping process is relatively cumbersome. When there are too many coins to be marked, the flipping workload is large, which greatly slows down the working efficiency. And using a motor to flip the coins will result in more motors being used, leading to an increase in the energy consumption of the picking and placing mechanism. Summary of the Utility Model

[0004] To solve the deficiencies of the prior art, this application discloses a single-motor goods picking and placing mechanism that only uses a single motor and can move and flip coins.

[0005] The present application discloses a single-motor picking and placing mechanism, which includes an object placement member, a driving member, a driving arm, a driving gear, and a guiding member. The object placement member includes a plurality of object placement slots with one side open. The driving member includes a driving motor, a driving slot provided above the driving motor, and a driving disk provided in the driving slot. A driving slot protruding portion protrudes upward around the driving slot. A hollow driving cavity is formed between the driving disk and the driving slot protruding portion. The driving motor is connected to the driving disk. The driving arm is provided above the driving disk. The driving arm includes a driving rod, a driven gear provided on one side of the driving rod, and a clamping portion provided on the other side of the driving rod. The driving motor can drive the driving disk to rotate, thereby driving the driving arm above the driving disk to rotate. The driving gear is provided below the driven gear, and the driven gear meshes with the driving gear. Two corresponding turning portions are provided on one side of the driving gear close to the driving slot. An upward protruding slideway is provided on one side of the driving slot close to the driving disk. The turning portions move on the slideway, and a part of the slideway is recessed downward. The guiding member is provided on one side of the driving slot close to the slideway, and the guiding member is provided above the recessed portion of the slideway. The width of the guiding member gradually increases from the end close to the slideway to the end far from the slideway. The distance between the bottom end of the guiding member and the slideway is greater than or equal to the distance between the two turning portions on the driving gear.

[0006] Further, the side of the guiding member far from the slideway is fixed to the driving slot by a fixing bolt. A through hole penetrating the driving slot is provided on the driving slot. A limiting bolt is provided on the side of the guiding member close to the slideway. One end of the limiting bolt is fixed to the guiding member, and the other end of the limiting bolt passes through the through hole of the driving slot. The width of the through hole of the driving slot is greater than the width of the limiting bolt.

[0007] Further, the shape of the guiding member is an isosceles triangle, and the vertex angle is close to the recessed portion of the slideway. The distance between the guiding member and the slideway is greater than or equal to the length of the width of the turning portion and less than the distance between the two turning portions on the driving gear.

[0008] Further, a pushing portion is provided on one side of the clamping portion close to the driving slot, and a butting portion corresponding to the pushing portion is provided on the side of the driving slot far from the slideway.

[0009] Further, the butting portion is a slidable pulley.

[0010] Further, a plurality of object placement slots surround one side of the driving disk, and the distances between the plurality of object placement slots and the center of the driving disk are the same.

[0011] Further, an adjusting member for adjusting the distance between the object placement slot and the driving disk is provided on the side of the object placement slot far from the driving disk.

[0012] Advantages of the present application:

[0013] 1. The single-motor picking and placing mechanism of this application realizes complex cargo picking, placing, and rotating actions through a single driving motor, reducing the number of motors and related driving components. This makes the structure of the entire mechanism more compact, occupies less space, and is convenient for installation and integration into related equipment. Using only one driving motor reduces the cost of the equipment and also reduces problems such as synchronization and coordination that may be brought by multiple motors, lowering the complexity and maintenance cost of the system.

[0014] 2. This application realizes a 180° turn of the clamping part only through the mechanical structure, reducing the participation of electronic control components and complex circuits. This reduces the risk of the turning function failing due to electronic component failures and circuit problems, making the entire turning action more stable and reliable. There is no need to use expensive electronic steering control components, sensors, and related control circuits, reducing the manufacturing cost and maintenance cost of the equipment. Compared with complex electronic control systems, the mechanical structure is relatively simple and intuitive. Maintenance personnel can more easily understand and diagnose problems, and it is easier to determine the fault location and replace or repair components during maintenance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to enable those skilled in the art to better understand the solutions of this utility model, the technical solutions in the specific embodiments of this utility model will be clearly and completely described below.

[0022] This application discloses a single-motor loading and unloading mechanism 100, as Figure 1 shown. The single-motor loading and unloading mechanism 100 includes an object placement member 11, a driving member 12, a driving arm 13, a driving gear 14, and a guiding member 15. The object placement member 11 includes a plurality of object placement grooves 111 with one side open. The object placement member 11 is used for placing goods, and the goods are placed in the object placement grooves 111. The goods can be coins. The driving member 12 includes a driving motor 121, a driving groove 122 provided above the driving motor 121, and a driving disk 123 provided in the driving groove 122. A driving groove protruding portion 1221 protrudes upward around the driving groove 122. A hollow driving cavity is formed between the driving disk 123 and the driving groove protruding portion 1221. The driving motor 121 is connected to the driving disk 123, and the driving motor 121 can drive the driving disk 123 to rotate. The driving arm 13 is provided above the driving disk 123. The driving arm 13 includes a driving rod 131, a driven gear 132 provided on one side of the driving rod 131, and a clamping portion 133 provided on the other side of the driving rod 131. The clamping portion 133 can clamp the goods and coins. The driving rod 131 fixes the goods and coins through the clamping portion 133. The driven gear 132 meshes with the driving gear 14. The driving motor 121 can drive the driving disk 123 to rotate, thereby driving the driving arm 13 above the driving disk 123 to rotate. As Figure 2 and Figure 3As shown in the figure, the driving gear 14 is arranged below the driven gear 132. Two corresponding steering parts 141 are arranged on one side of the driving gear 14 close to the driving groove 122. A sliding track 1222 protruding upward is arranged on one side of the driving groove 122 close to the driving disc 123. The steering parts 141 move on the sliding track 1222, and a part of the sliding track 1222 is recessed downward. When the steering parts 141 move on the sliding track 1222 to the part where the sliding track 1222 is recessed downward, the two steering parts 141 first approach the steering part 141 of the downward recessed sliding track 1222 and move along the downward recessed part of the sliding track 1222, thereby driving the driving gear 14 to rotate. The rotation of the driving gear 14 drives the driven gear 132 to rotate. The rotation of the driven gear 132 drives the driving rod 131 and the clamping part 133 on the other side of the driving rod 131 to rotate. When the steering part 141 reaches the bottom end of the downward recessed part of the sliding track 1222, the other steering part 141 moves from one side of the sliding track 1222 to the other side of the sliding track 1222. When the steering part 141 continues to move, the steering part 141 far from the bottom end of the downward recessed part of the sliding track 1222 moves out of the downward recessed part of the sliding track 1222. At this time, the steering part 141 will also drive the driving gear 14 to continue to rotate, thereby driving the clamping part 133 to rotate until the steering part 141 completely moves out of the downward recessed sliding track 1222. When the steering part 141 moves in the sliding track 1222, when the steering part 141 approaching the downward recessed sliding track 1222 moves downward along the sliding track 1222 until the bottom end of the downward recessed sliding track 1222, at this time the driving gear 14 rotates 45°. When the steering part 141 far from the downward recessed sliding track 1222 moves out of the downward recessed part of the sliding track 1222 until it completely moves out of the downward recessed sliding track 1222, the driving gear 14 rotates 45° again. During the whole movement process of the steering part 141 at the downward recessed sliding track 1222, the driving gear 14 rotates 180°, thereby driving the clamping part 133 to rotate 180°, and finally being able to drive the clamped goods or coins to rotate 180°. As Figure 4 and Figure 5 As shown in the figure, the guiding part 15 is used to limit the steering part 141 to ensure that the steering part 141 can move to the downward recessed part on the sliding track 1222. The guiding part 15 is arranged on one side of the driving groove 122 close to the sliding track 1222. The guiding part 15 is arranged above the recessed part of the sliding track 1222. The width of the guiding part 15 gradually increases from the width at one end close to the sliding track 1222 to the width at the side far from the sliding track 1222. The distance between the bottom end of the guiding part 15 and the sliding track 1222 is greater than or equal to the distance between the two steering parts 141 on the driving gear 14. On the one hand, it can prevent the steering part 141 from getting stuck at the downward recessed part on the sliding track 1222. On the other hand, it can enable the steering part 141 far from the bottom end of the downward recessed part of the sliding track 1222 to move out of the downward recessed part of the sliding track 1222 first.

[0023] The single-motor loading and unloading mechanism 100 of the present application first places goods such as coins in the placement groove 111 of the placement member 11, then clamps the goods through the clamping portion 133, and the driving motor 121 drives the driving disk 123 to rotate, thereby driving the driving arm 13 and the clamping portion 133 above the driving disk 123 to rotate. When the driving arm 13 moves, the two steering portions 141 on the driving gear 14 move on the slideway 1222 of the driving groove 122. When moving to the downwardly concave part of the upper part of the slideway 1222, the steering portion 141 closest to the downwardly concave slideway 1222 moves along the downwardly concave part of the slideway 1222, driving the driving gear 14 to rotate. When the steering portion 141 reaches the bottom end of the downwardly concave part of the slideway 1222, the other steering portion 141 moves from one side of the slideway 1222 to the other side. Continuing to move the steering portion 141, the steering portion 141 away from the bottom end of the downwardly concave part of the slideway 1222 moves out of the downwardly concave part of the slideway 1222, driving the driving gear 14 to continue rotating. The rotation of the driving gear 14 drives the rotation of the driven gear 132, thereby causing the driving rod 131 and the clamping portion 133 on the other side of the driving rod 131 to rotate. During the entire movement of the steering portion 141 at the downwardly concave slideway 1222, the driving gear 14 rotates 180°, driving the clamping portion 133 to rotate 180°, causing the clamped goods or coins to rotate 180°. The guiding member 15 plays a limiting role on the steering portion 141, ensuring that the steering portion 141 can move at the downwardly concave part of the slideway 1222, preventing the steering portion 141 from getting stuck, and causing the steering portion 141 away from the bottom end of the downwardly concave part of the slideway 1222 to move out of the downwardly concave part of the slideway 1222 first. The single-motor loading and unloading mechanism 100 of the present application realizes complex goods loading and unloading and rotation actions through a single driving motor 121, reduces the number of motors and related driving components, makes the structure of the entire mechanism more compact, occupies less space, and is convenient for installation and integration into related equipment. Only using one driving motor 121 reduces the cost of the equipment, and reduces problems such as synchronization and coordination that may be brought by multiple motors, reducing the complexity and maintenance cost of the system. The present application realizes a 180° rotation of the clamping portion 133 only through a mechanical structure, reduces the participation of electronic control components and complex circuits, reduces the risk of steering function failure caused by electronic component failures and circuit problems, and makes the entire steering action more stable and reliable. There is no need to use expensive electronic steering control components, sensors and related control circuits, reducing the manufacturing cost and maintenance cost of the equipment. Compared with complex electronic control systems, the mechanical structure is relatively simple and intuitive, and maintenance personnel are easier to understand and diagnose problems, and it is easier to determine the fault location and replace or repair components during maintenance. Through the above settings, it is convenient for the clamping portion 133 to clamp coins for flipping during marking, so as to mark both sides of the coins.

[0024] As an implementation manner, one side of the guide member 15 away from the slideway 1222 is fixed to the driving groove 122 by a fixing bolt 151. A through hole penetrating the driving groove 122 is provided on the driving groove 122. A limiting bolt 152 is provided on one side of the guide member 15 close to the slideway 1222. One end of the limiting bolt 152 is fixed to the guide member 15, and the other end of the limiting bolt 152 passes through the through hole of the driving groove 122. The width of the through hole of the driving groove 122 is greater than the width of the limiting bolt 152. Fixing the guide member 15 to the driving groove 122 by the fixing bolt 151 facilitates the installation and disassembly of the guide member 15. One end of the limiting bolt 152 is fixed to the guide member 15, and the other end passes through the through hole of the driving groove 122. The width of the through hole of the driving groove 122 is greater than the width of the limiting bolt 152. With such a setting, there can be a certain buffer displacement space when the steering part 141 passes through the bottom end of the guide member 15, ensuring that the movement of the steering part 141 is unobstructed and enabling the steering action to proceed smoothly and smoothly. The limiting bolt 152 plays a buffering role for the guide member 15, being able to buffer and limit the guide member 15 at the same time, reducing the hard collision and friction between the steering part 141 and the guide member 15, and reducing the risk of wear and damage of the components.

[0025] As an implementation manner, a pushing part 1331 is provided on one side of the clamping part 133 close to the driving groove 122, and an abutting part 1223 corresponding to the pushing part 1331 is provided on one side of the driving groove 122 away from the slideway 1222. The pushing part 1331 is used to push the goods, and the abutting part 1223 is used to abut against the pushing part 1331 to push the goods, so that the goods fall off the clamping part 133. Through the cooperation of the provided abutting part 1223 and the pushing part 1331 in this application, the goods can be pushed to fall off when the clamping part 133 rotates and moves to a position where the abutting part 1223 can abut against and push the pushing part 1331.

[0026] As an implementation manner, the abutting part 1223 is a slidable pulley. When the pushing part 1331 and the abutting part 1223 abut against each other to push the goods to make them fall off the clamping part 133, the sliding characteristic of the pulley can effectively reduce the friction between the pushing part 1331 and the abutting part 1223. The lower friction coefficient can reduce the wear speed of the components and extend the service life of the pushing part 1331 and the abutting part 1223. The sliding of the pulley can make the contact between the abutting part 1223 and the pushing part 1331 smoother, reducing the resistance during the pushing process and making the action of pushing the goods to fall off more rapid and efficient. Compared with a fixed rigid abutting part 1223, the friction noise generated by the sliding pulley during the contact and pushing with the pushing part 1331 will be greatly reduced, reducing the noise pollution during the operation of the equipment and providing a quieter condition for the working environment.

[0027] As an implementation manner, a plurality of storage grooves 111 are enclosed on one side of the driving disk 123, and the distances from the plurality of storage grooves 111 to the center of the driving disk 123 are the same. The fixed grooves have the same distance from the center of the driving disk 123, which is convenient for the clamping portion 133 to clamp the goods.

[0028] As an implementation manner, an adjusting member 1111 for adjusting the distance between the storage groove 111 and the driving disk 123 is provided on the side of the storage groove 111 away from the driving disk 123. The adjusting member 1111 can adjust the distance between the storage groove 111 and the driving disk 123, so that the storage groove 111 can install goods of various sizes, increasing the applicability of the single-motor goods picking and placing mechanism 100.
