[0033] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0034] See also Figures 1 to 7 As shown, an automatic auxiliary material placement device of the present invention includes a first feeding mechanism 1, a second feeding mechanism 2 and a transfer mechanism 3. The first feeding mechanism 1 is used to automatically supply auxiliary materials, the second feeding mechanism 2 is used to automatically supply circuit board components, and the transfer mechanism 3 is used to transfer the auxiliary materials supplied by the first feeding mechanism 1 to the circuit board components supplied by the second feeding mechanism 2.

[0035] The transfer mechanism 3 includes a first bracket 4, a second bracket 5 that moves horizontally back and forth along the first bracket 4, a first driving member for driving the second bracket 5 to reciprocate relative to the first bracket 4, a second driving member installed on the second bracket 5, a third bracket 6 connected to the output end of the second driving member, a fourth bracket 7 rotatably arranged on the third bracket 6, a third driving member for driving the fourth bracket 7 to rotate back and forth relative to the third bracket 6, and a first cylinder clamp 8 installed on the fourth bracket 7. The moving direction of the second bracket 5 is cross-set with the moving direction of the third bracket 6. In this embodiment, the moving direction of the second bracket 5 is perpendicular to the moving direction of the third bracket 6. The second bracket 5 moves back and forth in the horizontal direction, and the third bracket 6 moves back and forth in the vertical direction. The first cylinder clamp 8 is used to clamp the auxiliary materials supplied by the first feeding mechanism 1.

[0036] When the first cylinder clamp 8 is needed to clamp the auxiliary material, the third driving member drives the fourth bracket 7 to rotate according to the position of the auxiliary material. The rotating fourth bracket 7 rotates with the first cylinder clamp 8, thereby changing the relative angle between the first cylinder clamp 8 and the auxiliary material, and then the first cylinder clamp 8 accurately clamps the auxiliary material, ensuring that the auxiliary material can be accurately transferred to the circuit board component supplied by the second feeding mechanism 2.

[0037] During actual use, the first feeding mechanism 1 automatically supplies auxiliary materials, the second feeding mechanism 2 automatically supplies circuit board components, and the transfer mechanism 3 transfers the auxiliary materials supplied by the first feeding mechanism 1 to the circuit board components supplied by the second feeding mechanism 2, thereby realizing automatic placement of auxiliary materials. There is no need for staff to manually place auxiliary materials, thereby improving the placement efficiency and placement yield of auxiliary materials.

[0038] The transfer mechanism 3 also includes a fourth drive member mounted on the second bracket 5 and a suction member 9 connected to the output end of the fourth drive member. Preferably, the suction member 9 is a vacuum nozzle. The first feeding mechanism 1 includes a first feeding unit 11 and a second feeding unit 12, each of which supplies desiccant and a humidity meter. The first cylinder clamp 8 is used to clamp the desiccant, and the suction member 9 is used to absorb the humidity meter. The two feeding units, respectively, supply desiccant and humidity meter, further improve the feeding efficiency of the auxiliary materials and prevent feeding problems caused by different auxiliary materials.

[0039] The first feeding unit 11 includes a fifth bracket 13, a pneumatic scissors 14 installed on the fifth bracket 13, a material tray 15 rotatably set on the fifth bracket 13, and a fifth driving member for driving the material tray 15 to rotate. Multiple desiccants are connected to form a material roll wound around the outside of the material tray 15. The first cylinder clamp 8 is used to clamp the desiccant released by the material tray 15, and the pneumatic scissors 14 is used to cut the connection between the multiple desiccants released by the material tray 15.

[0040] During actual use, the fifth driving member drives the material tray 15 to rotate. After the material tray 15 rotates, the material roll wrapped around the outside of the material tray 15 is automatically released under the action of its own gravity. The pneumatic scissors 14 cuts off the desiccant after the material tray 15 is released. The first cylinder clamp 8 clamps the desiccant cut by the pneumatic scissors 14, and then the transfer mechanism 3 transfers the desiccant clamped by the first cylinder clamp 8 to the circuit board component conveyed by the second feeding mechanism 2.

[0041] The fifth bracket 13 is provided with a guide cylinder 16 and a guide unit 17. The guide cylinder 16 is provided with a through-hole penetrating the guide cylinder 16. The central axis of the through-hole extends in the vertical direction. The material roll released by the material tray 15 enters the through-hole after being guided by the guide unit 17. The guide unit 17 is used to guide the moving direction of the material roll to avoid the material roll released by the material tray 15 from moving improperly and not being able to be used normally.

[0042] The guide unit 17 has two rotating guide wheels 18, the rotation axes of the two guide wheels 18 are arranged in parallel, and the rotation axes of the guide wheels 18 are parallel to the horizontal plane. The material roll released by the material tray 15 is located between the two guide wheels 18. The two guide wheels 18 are used to stop the material roll released by the material tray 15 to ensure that the material roll released by the material tray 15 moves correctly.

[0043] Guide wheel 18 has an annular blind groove 19 recessed into its outer surface. It surrounds the guide wheel's rotational axis and accommodates the two opposing sides of the coil released from tray 15. The inner walls of the annular blind grooves 19 block and limit the coil released from tray 15, preventing it from becoming disengaged from the guide wheel 18 and causing movement problems. The rotation of guide wheel 18 creates rolling friction between the coil released from tray 15 and the guide wheel 18, reducing wear on the coil released from tray 15 by the guide unit 17.

[0044] A second cylinder clamp 21 is provided on the fifth bracket 13. The second cylinder clamp 21 and the pneumatic scissors 14 are located on the upper and lower sides of the guide unit 17. The second cylinder clamp 21 is located above the guide unit 17, and the pneumatic scissors 14 are located below the guide unit 17. The pneumatic scissors 14 are located between the guide unit 17 and the guide cylinder 16. The guide cylinder 16 is located below the pneumatic scissors 14, and the guide unit 17 is located between the second cylinder clamp 21 and the guide cylinder 16. The second cylinder clamp 21 is used to clamp the material roll released by the material tray 15.

[0045] After the material tray 15 releases the required material rolls, the second cylinder clamp 21 clamps the material roll released by the material tray 15 to prevent the material roll from being released continuously. Then the pneumatic scissors 14 cuts off the material roll clamped by the second cylinder clamp 21. Then the first cylinder clamp 8 clamps the desiccant of the material roll cut by the pneumatic scissors 14. The transfer mechanism 3 then moves the desiccant clamped by the first cylinder clamp 8 to the circuit board component supplied by the second feeding mechanism 2.

[0046] The pneumatic scissors 14 are slidably mounted on the fifth bracket 13. The fifth bracket 13 is provided with a sixth driving member for driving the pneumatic scissors 14. The sixth driving member drives the pneumatic scissors 14 to move between the guide unit 17 and the guide cylinder 16. In actual use, the sixth driving member drives the pneumatic scissors 14 to move up and down according to the length of the material roll to be cut, thereby changing the position of the pneumatic scissors 14 relative to the material roll released by the material tray 15, thereby allowing the material rolls to meet various length specifications.

[0047] The fifth bracket 13 is provided with a first clamping plate 22 and a seventh driving member. The output end of the seventh driving member is connected to the second clamping plate 23. The seventh driving member drives the second clamping plate 23 to move closer to or away from the first clamping plate 22. The two clamping plates are used to clamp the desiccant. The guide tube 16 is located between the pneumatic scissors 14 and the clamping plates. The first cylinder clamp 8 is used to clamp the desiccant clamped by the two clamping plates.

[0048] During actual use, the second cylinder clamp 21 clamps the upper part of the material roll released by the material tray 15, and the two clamps clamp the lower part of the material roll released by the material tray 15. The pneumatic scissors 14 cuts the material roll released by the material tray 15 between the second cylinder clamp 21 and the clamps. Then the first cylinder clamp 8 clamps the material roll released by the material tray 15 clamped by the two clamps, and then the two clamps release the material roll. Then the transfer mechanism 3 moves the material roll clamped by the first cylinder clamp 8 to the circuit board component supplied by the second feeding mechanism 2.

[0049] The second feeding unit 12 includes a sixth bracket 24, a material containing barrel 25 installed on the sixth bracket 24, a top plate 26 lifted and lowered on the sixth bracket 24, an eighth driving member for driving the top plate 26 to move up and down, a ninth driving member installed on the sixth bracket 24, and a cover plate connected to the output end of the ninth driving member. The material containing barrel 25 is provided with a material containing chamber passing through the material containing barrel 25, and the material containing chamber extends in the vertical direction. The top plate 26 is located in the material containing chamber and is used to support the stacked humidity cards in the material containing chamber. The ninth driving member drives the cover plate to cover the opening of the material containing chamber. The suction member 9 is used to absorb the humidity cards in the material containing chamber through the opening of the material containing chamber.

[0050] In actual use, after the suction member 9 of the transfer mechanism 3 removes the topmost humidity card from the storage barrel 25, the eighth drive member drives the top plate 26 to raise the remaining stacked humidity cards in the storage chamber by the height of one humidity card, ensuring that the suction member 9 can continuously remove humidity cards from the predetermined position. When the auxiliary material automatic placement device is shut down, the ninth drive member drives the cover plate to cover the opening of the storage chamber, thereby enclosing the stacked humidity cards in the storage barrel 25 and preventing humidity changes in the humidity cards that could cause them to malfunction.

[0051] The second feeding mechanism 2 includes a seventh bracket 27, an annular belt 28 rotatably arranged on the seventh bracket 27, and a tenth driving member for driving the annular belt 28 to rotate. There are two annular belts 28, and the two annular belts 28 are used to support the two ends of the circuit board component away from each other; a plurality of internal teeth are provided on the annular belt 28, and the internal teeth are protruding from the inner surface of the annular belt 28, and the plurality of internal teeth extend along the length direction of the annular belt 28; the seventh bracket 27 is provided with a plurality of rotating gears 29, and the annular belt 28 is sleeved on the outside of the gear 29, and the gear 29 is engaged with the internal teeth.

[0052] In actual use, the ends of the circuit board components are respectively pressed against the two endless belts 28. The tenth driving member drives at least one gear 29 to rotate. The rotating gear 29 drives the endless belt 28 to rotate, and the rotating endless belt 28 drives the carried circuit board components to automatically move. The meshing of the gears 29 and the internal teeth of the endless belt 28 reduces the chance of the endless belt 28 slipping, ensuring that the endless belt 28 can stably transport the circuit board components.

[0053] The second feeding mechanism 2 is also equipped with a carrier 31 for carrying circuit boards. Specifically, the circuit boards are held against the carrier 31 under the action of gravity. The carrier 31 has a blind receiving groove 32 and a plurality of supporting protrusions 33 located within the blind receiving groove 32. The blind receiving groove 32 is recessed from the top surface of the carrier 31, and the circuit boards are held against the plurality of supporting protrusions 33. The structural design of the blind receiving groove 32 and the supporting protrusions 33 reduces the contact area between the circuit boards and the carrier 31, preventing the circuit boards from becoming stuck to the carrier 31 and becoming immovable.

[0054] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
