Detailed implementation manners

[0038] Embodiment:

[0039] Please refer to Figures 1-9, this embodiment is a full-automatic glue-applying machine 100 for bit heads, which includes a first driving unit 1, a vertically arranged rotating disk 2 driven by the first driving unit 1 to rotate, a plurality of clamping fixtures 3 arranged on the rotating disk 2, a feeding unit 4 for automatically feeding bit heads, a feeding unit 5 for pushing a single bit head at the end of the feeding unit 4 into the clamping fixture 3, a glue-applying and scraping unit 6 and a baking unit 7 arranged around the periphery of the rotating disk 2, a second driving unit 8 arranged corresponding to the position of the glue-applying and scraping unit 6 and realizing the rotation of the clamping fixture 3, and a discharging unit 9 for pushing out the bit head in the clamping fixture 3 to realize discharging.

[0040] The feeding unit 4 includes a feeding bin 42 with an inclined bottom plate 41, a lifting plate 43 arranged on the low-position side of the inclined bottom plate 41 of the feeding bin 42, a first air cylinder 44 for driving the lifting plate 43 to move up and down and only pushing out one product, and a linear vibrator 45 docked with the top end of the lifting plate 43. The upper surface of the lifting plate 43 is an inclined surface, and an inclined guide plate 46 is arranged at its high position for docking, so that the products on the lifting plate 43 can automatically roll onto the inclined guide plate 46 and then enter the linear vibrator 45. The operator can place several bit heads in the feeding bin 42 at one time. Under the guidance of the inclined bottom plate 41, the bit heads roll towards the low position. The first air cylinder 44 drives the lifting plate 43 to lift, pushes out one product, and then enters the linear vibrator 45 under the guiding action of the inclined guide plate 46.

[0041] The first driving unit 1 includes a first driving member 11 and a divider 12 driven by the first driving member 11 to perform rotational output. The rotating disk 2 is fixedly connected to the output main shaft 13 of the divider 12.

[0042] The clamping fixture 3 includes a loading bushing 31 arranged on the rotating disk 2 through a bearing, a first ejector rod 33 arranged in the loading bushing 31 that can rotate synchronously with the loading bushing 31 but can slide axially, and a limit rotation driving block 34 fixed on the loading bushing 31. The first ejector rod 33 is axially abutted against the end far from the loading bushing 31 through a first spring 36. The other end of the loading bushing 31 forms a receiving groove (not marked in the figure) for sleeving the end of the product. The receiving groove is shaped to conform to the outer contour of the end of the bit head and realizes rotational transmission.

[0043] The clamping fixture 3 also includes an anti-rotation unit 35 which is arranged on the rotating disk 2 and cooperates with the limited rotation driving block 34 to stop the loading sleeve 31 from rotating and stop it at a desired angle. The limited rotation driving block 34 axially includes a circular ring portion 341 and a rotation stop portion 342. The outer contour of the rotation stop portion 342 is contoured to the contour of the end of the screwdriver bit and corresponds to the shape of the storage groove 32. The anti-rotation unit 35 includes a support 351 fixed on the rotating disk 2, a rotation stop frame 353 rotatably mounted on the support 351 through a pin 352, and a second spring 354 that pushes one side of the rotation stop frame 353 upward so that it rotates around the pin 352 and presses the limited rotation driving block 34. The anti-rotation frame 353 includes a clamping arm 3531 and an unlocking arm 3533 which are located on both sides of the limited rotation drive block 34 and form a lever structure, and a connecting mounting portion 3532 connecting the clamping arm 3531 and the unlocking arm 3533. The connecting mounting portion 3532 is mounted on the support 351 through the above-mentioned pin shaft 352. The clamping arm 3531 and the unlocking arm 3533 are located on both sides of the pin shaft 352. One end of the second spring 354 abuts against the lower surface of one end of the connecting mounting portion 3532 and the other end abuts against the surface of the rotating disk 2. When there is no need to rotate the clamping jig 3, the clamping arm 3531 radially presses one of the planes of the anti-rotation part 342. Since the anti-rotation part 342 is a polygonal structure, anti-rotation is achieved according to its structural characteristics and the clamping force of the clamping arm 3531. When the clamping jig 3 needs to rotate, the anti-rotation frame 353 is slightly rotated around the pin shaft 352 by squeezing the unlocking arm 3533 on the other side, and the clamping arm 3531 that was originally close to the anti-rotation part 342 releases the clamping force on the anti-rotation part 342, so that the clamping jig 3 has rotational freedom.

[0044] Since an ordinary single-phase asynchronous motor has a random stopping position when driving the clamping fixture 3 to rotate and has no directional stopping capability, this embodiment adopts the shape design of the stop portion 342 of the limited rotation drive block 34, the corresponding shape design of the storage groove 32, and the structural design of the clamping arm 3531 in the stop frame 353. The clamping arm 3531 presses one of the planes of the stop portion 342. Regardless of where the second drive member 81 stops, the loading sleeve 31 can stop at the required angle, thereby ensuring that the product can be smoothly pushed into the clamping fixture 3 at the loading station.

[0045] The second driving unit 8 includes a second driving member 81, a driving wheel 82 that is driven by the second driving member 81 to rotate and simultaneously drives the limit rotation driving block 34 to rotate, and an unlocking block 83 that unlocks the anti-rotation unit 35 in the clamping fixture 3 so that the clamping fixture 3 has a rotational freedom. The driving wheel 82 abuts against and adheres to the circular ring portion 341 of the limit rotation driving block 34 to achieve rotational transmission. When the clamping fixture 3 rotates to the position of the second driving unit 8, first, the unlocking block 83 presses the unlocking arm 3533 on one side of the rotation stopping frame 353, so that the clamping fixture 3 has a rotational freedom. Then, the driving wheel 82 rotates to drive the limit rotation driving block 34 to rotate synchronously, thereby driving the entire clamping fixture 3 and the product to rotate together.

[0046] The loading unit 5 includes a transfer groove (not marked in the figure) that is docked with the output end of the feeding unit 4, a second ejecting rod 51 that ejects the product in the transfer groove into the clamping fixture 3, and a third driving unit 52 that drives the second ejecting rod 51 to perform a horizontal linear motion.

[0047] The third driving unit 52 includes a third spring 521 that pulls the second ejecting rod 51 along the product ejection direction, and a pulling rod 522 that pulls the second ejecting rod 51 in the reverse direction of the product ejection direction.

[0048] In this embodiment, the ejecting force for ejecting the product into the clamping fixture 3 adopts elastic ejection, effectively avoiding the occurrence of product damage caused by rigid ejection of the product.

[0049] The second ejecting rod 51 is fixed on a connecting block 53. The connecting block 53 is arranged in a sliding hole through a guide rod to limit and guide the movement track of the connecting block 53. A roller 54 is arranged on the connecting block 53. The third driving unit 52 further includes a cam 523 fixedly arranged on the input shaft 14 of the indexing device 12, and a transmission unit that cooperates with the cam 523 to drive the pulling rod 522 to move. The transmission unit includes a swing rod 525 that is driven by the cam 523 to swing around a rotating shaft 524, a transmission rod 526 that is hinged to the end of the swing rod 525, and a swing plate 528 that is hinged to the end of the transmission rod 526 and is driven by it to rotate around another rotating shaft 527. The pulling rod 522 is fixed on the swing plate 528 and is arranged to abut against the roller 54.

[0050] The blanking unit 9 includes a connecting rod 91 with one end hinged to the swing rod 525, and a blanking block 92 hinged to the other end of the connecting rod 91 and sliding in a chute. The blanking block 92 is correspondingly arranged with the first blanking rod 33 in the clamping fixture 3. By the swing of the swing rod 525, the blanking block 92 is driven to perform a horizontal linear motion at the same time, and then the first blanking rod 33 is driven to eject the product in the clamping fixture 3 to realize blanking. At the same time, by the swing of the swing rod 525, the transmission rod 526 and the swing plate 528 are driven to move, and then the horizontal linear motion of the second blanking rod 51 is realized by using the pulling rod 522 and the third spring 521 to realize the feeding of the product, so as to realize the synchronous connection of feeding and blanking, and use the same driving source as the rotating disk, which greatly saves costs while improving the action synchronism.

[0051] The gluing and scraping unit 6 includes a second air cylinder 61, a glue gun assembly 62 driven by the second air cylinder 61 to approach or move away from the product on the clamping fixture 3, a third air cylinder 63, and a scraping film 64 driven by the third air cylinder 63 to approach or move away from the product on the clamping fixture 3. Since there is a gap between the clamping fixture 3 and the hexagon bit, if the gap is too small, it is easy to get stuck during loading and unloading. Therefore, the gap will be designed appropriately. When the clamping fixture 3 rotates, the bit will be eccentric, resulting in uneven thickness on both sides of the scraping. However, the scraping film 64 in this embodiment adopts an elastic floating thin sheet structure, which can effectively make up for the eccentricity of the bit and improve the scraping effect.

[0052] At the gluing station, in order to prevent the product from falling out when rotating with the clamping fixture 3, a holding rotating sleeve (not marked in the figure) that holds the free end of the product and rotates synchronously with it, and a fourth air cylinder (not marked in the figure) that drives the holding rotating sleeve to approach or move away from the product in the clamping fixture 3 are also provided in this embodiment at the gluing station.

[0053] This embodiment further includes a blanking output unit 10 located at the blanking station.

[0054] The baking unit 7 includes an oven housing 71 and a plurality of heating sources arranged in the oven housing 71. The heating sources include but are not limited to UV lamps, heating rods, or hot air inlet pipes, etc. The oven housing 71 covers a plurality of clamping fixtures 3, so that the glue on the product can be baked for a sufficient time, ensuring the baking time and reducing the beat, and improving the production efficiency.

[0055] The working principle of this embodiment of a full-automatic hexagon bit gluing machine 100 is as follows:

[0056] 1) Put a number of hexagon bits into the feeding bin 42 at one time, and then one product is ejected by the lifting plate 43 at a time and slides into the linear vibrating mechanism 45, and then is vibrated to the end and enters the transfer groove;

[0057] 2) The second ejector rod 51 in the loading unit 5 ejects the product into the loading bushing 31 of the clamping fixture 3 under the elastic force of the third spring 521;

[0058] 3) The product rotates with the rotating disk 2 in the clamping fixture 3 to the gluing station. The unlocking block 83 unlocks the anti-rotation unit 35. The fourth cylinder extends. The holding rotating sleeve holds the free end of the bit. The second cylinder 61 extends. The glue outlet of the glue gun assembly 62 is aligned with the gluing position. The third cylinder 63 extends. The scraping film 64 is aligned with the product gluing position. The second driving member 81 drives the clamping fixture 3 to rotate, and at the same time drives the product to rotate synchronously to complete gluing and scraping;

[0059] 4) The product rotates with the rotating disk 2 in the clamping fixture 3 through the baking unit 7, and after baking, it rotates to the unloading station;

[0060] 5) Under the ejection action of the ejector block 92 and the transmission action of the first ejector rod 33, the product is ejected from the clamping fixture 3 and falls onto the unloading output unit 10 to realize unloading output.

[0061] The beneficial effects of this embodiment of a fully automatic bit gluing machine 100 are as follows: A cam structure is arranged on the input shaft of the indexer, and a transmission structure is designed to realize the linkage synchronization of loading and unloading and the rotating disk, greatly reducing the manufacturing cost; By cleverly designing the clamping fixture structure and cooperating with the anti-rotation unit to realize the directional function of the clamping fixture, no matter when the driving motor drives the clamping fixture to stop at any point, the clamping fixture can self-adjust to the required angle to ensure the smooth loading of the next product; The scraping film with elastic floating function is adopted to effectively compensate for the eccentric movement of the bit and improve the scraping effect; It realizes the fully automatic operation integrating loading, gluing, scraping, baking and unloading, greatly improving the production efficiency, and has a compact structure and small equipment space occupation.

[0062] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
