[0022] The following is combined Figures 1-2 This utility model will be described in detail.

[0023] Example

[0024] Depend on Figure 1-2It is known that an ointment swing arm feeding mechanism includes a fixed plate 1, which serves as the mounting base for the entire mechanism. Its bottom is fixedly connected to the production line frame through a fixed seat 8 to ensure the overall stability of the mechanism.

[0025] A first drive assembly 2 is mounted on a fixed plate 1, and a swing arm assembly 3 is mounted on the first drive assembly 2. The first drive assembly 2 includes a first reducer 201 mounted on a reducer fixed plate 202, and a first motor 203 is mounted on the input end of the first reducer 201. The first reducer 201 is fixedly connected to the reducer fixed plate 202 by bolts, and the first motor 203 provides power for the rotation of the swing arm assembly 3. The first reducer 201 is used to reduce the speed and increase the output torque.

[0026] The swing arm assembly 3 includes a rotating shaft 302 installed at the output end of the first reducer 201, and the two can be fixed by a key connection. The end of the rotating shaft 302 is rotatably connected to the bearing housing 304 through a bearing, realizing axial positioning and rotational support.

[0027] A swing arm 303 is fixedly connected to the rotating shaft 302, and the swing arm 303 can be fixed to the rotating shaft 302 by a key connection. The suspended end of the swing arm 303 is rotatably connected to a fixed shaft 308 through a bearing. A vacuum suction assembly 4 is installed at one end of the fixed shaft 308, and a rotating pulley 306 is fixedly connected to the other end through a tensioning sleeve 307.

[0028] The rotating pulley 306 is engaged with the first synchronous belt 305, and the other end of the first synchronous belt 305 is engaged with the fixed pulley 301. The fixed pulley 301 is sleeved on the rotating shaft 302 and fixedly connected to the reducer fixing plate 202.

[0029] The vacuum suction assembly 4 includes a suction head holder 401 mounted on a fixed shaft 308, a suction head 402 mounted on the suction head holder 401, a vacuum suction cup 403 mounted on the suction head 402, and a pressure block 404 mounted on the suction head holder 401 for fixing the suction head holder 401 to the fixed shaft 308.

[0030] The pressure block 404 presses the suction head fixing seat 401 onto the fixed shaft 308 by bolt connection, so that the suction head 402 installed on the suction head fixing seat 401 and the vacuum suction cup 403 at the end of the suction head 402 rotate synchronously with the fixed shaft 308.

[0031] At least one set of vacuum material suction assembly 4 should be installed. Workers can install vacuum material suction assemblies as needed, and are not limited to two sets.

[0032] Two vacuum suction cups 403 are provided on the suction head holder 401. The vacuum suction cups 403 use negative pressure to adsorb ointment materials, achieving flexible gripping. In addition, operators can replace the vacuum suction cups 403 with different sizes according to the specifications of the materials.

[0033] Driven by the first drive assembly 2, the rotating shaft 302 rotates, simultaneously causing the swing arm 303, which is fixedly connected to the rotating shaft 302, to rotate. However, to ensure that the load mounted on the swing arm 303 (i.e., the vacuum suction cup 403 in the vacuum suction assembly 4) always faces downwards towards the material, a fixed pulley 301 is designed. Since the fixed pulley 301 cannot rotate, the first synchronous belt 305 will also not rotate. However, because a fixed shaft 308 is rotatably connected to the swing arm 303 via a bearing, and the fixed shaft 308 is fixedly connected to the rotating pulley 306 via a shrink sleeve 307, the rotating pulley 306 will revolve with the swing arm 303. With the fixed pulley 301 stationary and the first synchronous belt 305 in constant spatial position, if the rotating pulley 306 were to revolve with the swing arm 303, it must roll on the first synchronous belt 305. If it did not roll, it would inevitably skip teeth or become stretched; therefore, it can only roll.

[0034] Under normal circumstances, the rotating pulley 306 would slide on the first synchronous belt 305 as the swing arm 303 revolves in an arc. However, since the fixed pulley 301 and the first synchronous belt 305 cannot rotate, the rotating pulley 306 is forcibly constrained, allowing it to rotate and roll around its own axis to maintain engagement with the first synchronous belt 305. The rotating pulley 306 drives the fixed shaft 308 to rotate around the swing arm 303, thereby driving the vacuum suction assembly 4 mounted on the fixed shaft 308 to rotate.

[0035] Since the fixed pulley 301 and the rotating pulley 306 have the same number of teeth, the rotation and revolution of the rotating pulley 306 cancel each other out, ensuring that the load on the fixed shaft 308 (i.e., the vacuum suction cup 403 in the vacuum suction assembly 4) is always facing downwards and aligned with the material.

[0036] A limiting component 5 is also installed on the fixed plate 1. The limiting component 5 includes a guide rail fixing plate 501 fixedly connected between the bearing seat 304 and the reducer fixing plate 202. A slider 502 is fixedly connected to the guide rail fixing plate 501. The slider 502 is slidably connected to the guide rail 503. The guide rail 503 is fixedly connected to the fixed plate 1.

[0037] Two sets of limit components 5 are provided, and the two sets of limit components 5 are symmetrically installed on both sides of the bearing housing 304. A second drive component 6 is installed on one set of limit components 5.

[0038] The second drive assembly 6 includes a second motor 606 mounted on a fixed plate 1. A second reducer 601 is mounted on the output end of the second motor 606. A drive pulley 602 is mounted on the output end of the second reducer 601. The drive pulley 602 is connected to a driven pulley 604 via a second synchronous belt 603. The driven pulley 604 is rotatably connected to the fixed plate 1 via bearings. The second synchronous belt 603 is arranged along the direction of the guide rail 503. A clamping plate 605 is mounted on the guide rail fixed plate 501 and clamps the second synchronous belt 603.

[0039] The second motor 606 drives the second reducer 601 to rotate, and the second reducer 601 drives the drive pulley 602 to rotate. Under the drive of the second synchronous belt 603, the driven pulley 604 rotates. At the same time, since the second synchronous belt 603 is also fixedly connected to the clamping plate 605, which is fixed on the guide rail fixing plate 501, when the second synchronous belt 603 is in motion, the slider 502 at the bottom of the guide rail fixing plate 501 slides along the guide rail 503. This ultimately enables the swing arm assembly 3 and the first drive assembly 2 on the guide rail fixing plate 501 to move horizontally and match the corresponding production line operation.

[0040] In another set of limiting components 5, both ends of the guide rail 503 are provided with limiting blocks 9. The limiting blocks 9 are mounted on the fixed plate 1, and buffer blocks 10 are also installed on the limiting blocks 9. The limiting blocks 9 limit the horizontal movement limit of the guide rail fixed plate 501, while the buffer blocks 10 provide buffer protection.

[0041] Two buffer pads 7 are installed on the guide rail fixing plate 501, and the two buffer pads 7 are symmetrically arranged on both sides of the rotating shaft 302. The buffer pads 7 are used to limit the swing limit position of the swing arm 303 and reduce mechanical impact.

[0042] Specifically, when using this ointment swing arm feeding mechanism,

[0043] In the initial state, the swing arm 303 is in the initial position. The second drive component 6 drives the swing arm component 3 to move horizontally along the guide rail 503 to the appropriate position according to the material feeding position requirements.

[0044] When the material is grasped, the first motor 203 starts and drives the rotating shaft 302 to rotate via the first reducer 201, which in turn drives the swing arm 303 to swing to the loading position. The vacuum suction cup 403 is connected to the negative pressure to adsorb the ointment material.

[0045] When transferring materials, the first motor 203 rotates in the opposite direction, and the swing arm 303 carries the materials to the unloading position. During the swing, under the action of the fixed pulley 301, the first synchronous belt 305 and the rotating pulley 306, the vacuum suction assembly 4 always maintains a downward posture to ensure the stability of the materials.

[0046] Release the material, swing arm 303 reaches the unloading position, vacuum suction cup 403 releases negative pressure, and the material falls to the designated position;

[0047] In the reset cycle, the swing arm 303 is reset under the drive of the first drive component 2, while the second drive component 6 can adjust its horizontal position as needed to prepare for the next gripping and transfer cycle.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
