Detailed Description
In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.
The existing material stirring device is provided with a plurality of motors, the motors synchronously control a plurality of material stirring mechanisms to move up and down so as to stir the lead frame, and the existing material stirring device has the problems that the driving structure is complex, the stirring synchronization degree of the plurality of material stirring mechanisms is difficult to ensure, and therefore the conveying stability of the lead frame is reduced.
In view of the above, the present utility model provides a lead frame stirring device for stirring a lead frame carried on a guide rail so that the lead frame moves along the guide rail. As shown in fig. 1, the lead frame material stirring device in the embodiment of the utility model comprises a bottom plate 1, a translation rod 2, a translation driving mechanism 3, a lifting driving mechanism 4 and a plurality of material stirring components 5, wherein:
the bottom plate 1 is arranged above the guide rail.
The translation rod 2 is arranged on the base plate 1 along the extending direction of the guide rail (such as the X-axis direction in fig. 1), and a plurality of material stirring assemblies 5 are arranged on the translation rod 2.
The lifting driving mechanism 4 is arranged on the bottom plate 1, and the lifting driving mechanism 4 is used for driving the translation rod 2 to lift so as to drive the plurality of stirring assemblies 5 to synchronously lift.
The translation driving mechanism 3 is arranged on the bottom plate 1, and the translation driving mechanism 3 is used for driving the translation rod 2 to translate along the extending direction of the guide rail so as to drive the plurality of stirring assemblies to translate synchronously.
The driving process of the lead frame material stirring device to the lead frame is as follows:
first, the lifting driving mechanism 4 drives the translation rod 2 to descend, so that each material stirring assembly 5 is inserted into the corresponding lead frame.
Then, the translation driving mechanism 3 drives the translation rod 2 to translate, so that each material stirring assembly 5 drives the corresponding lead frame to slide forwards along the guide rail for a preset distance.
After the material stirring operation is completed, the lifting driving mechanism 4 drives the translation rod 2 to ascend and return to the original position, and the translation driving mechanism 3 drives the translation rod 2 to return to the original position.
The above process is repeated, and the lead frame can be driven to move forwards along the guide rail in a stepping mode.
Because all the material shifting components 5 are arranged on the translation rod 2, the lifting driving mechanism 4 and the translation driving mechanism 3 are matched to drive the translation rod 2 to lift and translate, and can drive all the material shifting components 5 to synchronously shift the lead frames on the guide rails forwards. Therefore, the lead frame stirring device can ensure the stirring synchronization degree of a plurality of stirring assemblies 5 and ensure the conveying stability of the lead frame.
As shown in fig. 1, the material stirring assembly 5 comprises a stirring needle mounting plate 51 and a stirring needle 52, wherein the stirring needle mounting plate 51 is connected to the translation rod 2, and the stirring needle 52 is vertically arranged on the stirring needle mounting plate 51. The poking needle 52 is used as a poking end of the poking assembly 5, so that the poking assembly 5 can be ensured to smoothly extend into the lead frame to poke the lead frame.
As shown in fig. 2 to 3, the translational driving mechanism 3 may optionally include a first mounting block 31, a connecting plate 32, a first driving motor (not shown), a first roller 33, a second roller 34, and a push ring 35, wherein: the first installation piece 31 is fixedly connected to the bottom plate 1, a first guide rail 36 parallel to the translation rod 2 is arranged on the first installation piece 31, and the connecting plate 32 is connected to the first guide rail 36 in a sliding mode. The first roller 33 and the second roller 34 are arranged in pairs on the connecting plate 32. The push ring 35 is fixedly mounted on the translation bar 2 and is located between the first roller 33 and the second roller 34, and the first roller 33 and the second roller 34 are configured to be able to approach toward the middle or separate toward both sides to clamp or release the push ring 35. The first driving motor is disposed on the first mounting block 31, and the first driving motor is used for driving the connecting plate 32 to slide along the first guide rail 36, so as to drive the translation rod 2 to translate through the pushing ring 35.
When the first driving motor is required to perform the translational driving of the translational rod 2, the first roller 33 and the second roller 34 are moved closer to each other to perform the clamping and holding of the push ring 35. Then, the first driving motor drives the connecting plate 32 to slide along the first guide rail 36, so that the translation rod 2 is driven to translate by the pushing ring 35.
When the lifting driving mechanism 4 needs to drive the translation rod 2 to lift, the first roller 33 and the second roller 34 are separated to two sides, so that the pushing ring 35 is released, and the translation rod 2 can be lifted smoothly.
Of course, the translation driving mechanism 3 may also adopt a translation driving device of other existing structures, as long as it can drive the translation rod 2 to translate, and does not obstruct the lifting of the translation rod 2.

Since the connection block 44 is slidably coupled to the translation rod 2 and can slide along the translation rod 2. Thus, the elevation drive mechanism 4 does not cause an obstruction to the translation of the translation rod 2. That is, the lift drive mechanism 4 does not interfere with the translational drive of the translational rod 2 by the translational drive mechanism 3.

9. The leadframe flag of claim 8, wherein the hold-down mechanism includes a plurality of hold-down assemblies and a lift drive, wherein:
the plurality of compression assemblies are arranged along the extending direction of the guide rail, each compression assembly comprises a second installation block, a lifting block and a compression rod, the second installation blocks are installed on the bottom plate, the second installation blocks are provided with second guide rails extending along the vertical direction, the lifting blocks are connected to the second guide rails in a sliding mode, and the compression rods are connected to the lifting blocks;
the lifting driving part is in transmission connection with the lifting blocks of the pressing assemblies, and is used for driving the lifting blocks of the pressing assemblies to slide up and down along the corresponding second guide rails so as to drive the pressing rods of the pressing assemblies to synchronously lift, and each pressing rod is used for pressing or releasing at least one lead frame.
10. The leadframe stirring apparatus of claim 9, wherein the elevation drive portion comprises a third drive motor, a rotary drive shaft, a plurality of cams, and a plurality of drive bars, wherein:
the rotary driving shafts are rotatably arranged on the bottom plate, and the cams are fixedly arranged on the rotary driving shafts and correspond to the compression assemblies one by one;
the plurality of transmission rods are in one-to-one correspondence with the compression assemblies, the first ends of the transmission rods are fixedly connected to the lifting blocks of the corresponding compression assemblies, the second ends of the transmission rods are provided with cam followers, and the cam followers are pressed against the corresponding cams;
the third driving motor is arranged on the bottom plate and used for driving the rotary driving shaft to rotate, and the cam and the transmission rod drive the lifting block of the pressing assembly to slide up and down along the corresponding second guide rail when the rotary driving shaft rotates.
