[0001] This application relates to the technical field of bulb production equipment, and particularly relates to a lamp holder feeding device. Background Art

[0002] During the production process of bulbs, first, the lamp core is installed on the bulb shell, and then the lamp holder is installed on the bulb shell, and one of the filaments of the lamp core passes through the through hole of the lamp holder. In related technologies, regarding the installation method of the lamp holder, generally, a manipulator clamps the lamp holder and moves it above the bulb shell, aligns the through hole of the lamp holder with the filament on the bulb shell, and then the manipulator lowers the lamp holder so that the lamp holder descends and is placed on the bulb shell, and the filament passes through the through hole of the lamp holder. However, when the filament is slightly skewed, the inner wall of the lamp holder may contact the filament during the descent of the lamp holder, resulting in the filament being bent and unable to pass through the through hole of the lamp holder, leading to defective assembled bulbs.

[0042] Referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 According to an embodiment of this application, a lamp holder feeding device includes: a clamping part 110, a clamping driving part 120, a guiding part 210, a guiding driving part 220, a feeding part 310, and a feeding driving part 320.

[0043] The clamping driving part 120 is drivingly connected to the clamping part 110 and is used to make the clamping part 110 clamp or release the filament.

[0044] A guiding channel 211 is formed inside the guiding part 210, and the entrance of the guiding channel 211 faces the clamping part 110.

[0045] The guiding driving part 220 is drivingly connected to the guiding part 210 and is used to make the guiding part 210 approach or move away from the clamping part 110.

[0046] The feeding part 310 is used to clamp the lamp holder.

[0047] The feeding driving part 320 is drivingly connected to the feeding part 310 and is used to drive the feeding part 310 to move between the guiding part 210 and the clamping part 110.

[0048] One operation process of the lamp holder feeding device of this application is as follows:

[0049] The clamping part 110 is located above the fixture 810. A bulb shell 820 with a wick installed is fixed on the fixture 810. The clamping driving part 120 drives the clamping part 110 to clamp one of the filaments of the wick, so as to play a role in guiding the filament. After the clamping part 110 completes the guiding of the filament, the clamping driving part 120 drives the clamping part 110 to release the filament. The guiding part 210 is located above the clamping part 110. The feeding part 310 clamps the lamp head, and the feeding driving part 320 drives the feeding part 310 to move between the guiding part 210 and the clamping part 110, so that the guiding part 210 aligns with the through hole of the lamp head and aligns with the filament. The guiding driving part 220 drives the guiding part 210 to approach the clamping part 110, that is, to move the guiding part 210 downward. The guiding part 210 first passes through the through hole of the lamp head, and then the filament will penetrate into the guiding channel 211 from the entrance of the guiding channel 211 and surround the outside of the filament through the guiding part 210. Then, the feeding driving part 320 drives the feeding part 310 to move downward, or the feeding part 310 releases the lamp head, so that the lamp head moves downward, and the lamp head approaches and lands on the clamping part 110. Since the guiding part 210 passes through the through hole of the lamp head and the filament is located in the guiding channel 211 of the guiding part 210, during the downward movement of the lamp head, it will definitely not contact the filament. After the lamp head lands on the lamp head, the guiding driving part 220 drives the guiding part 210 to move away from the clamping part 110, that is, to move the guiding part 210 upward, so that the guiding part 210 leaves the through hole of the lamp head and exposes the filament, so as to realize that the filament passes through the lamp head and the lamp head lands on the bulb shell 820. Subsequently, the lamp head can be screwed by manual or mechanical hand to realize the assembly of the lamp head and the bulb shell 820.

[0050] In summary, the clamping part 110 cooperates with the clamping driving part 120 to guide the filament on the bulb shell 820. The cooperation of the feeding part 310 and the feeding driving part 320 positions the lamp head between the guiding part 210 and the clamping part 110. The guiding driving part 220 drives the guiding part 210 to pass through the through hole of the lamp head and enables the filament to enter the guiding channel 211 of the guiding part 210. During the downward movement of the lamp head, it is guided by the guiding part 210, and the guiding part 210 plays a role in protecting the filament. Therefore, during the process of the lamp head falling onto the bulb shell 820, the lamp head will not contact the filament, and after the lamp head lands on the bulb shell 820, the guiding part 210 leaves the lamp head and the filament. At this time, the filament has passed through the lamp head, avoiding the problem of product defects caused by the collision between the downward movement of the lamp head and the filament, and improving the yield rate of the produced bulbs.

[0051] In some other embodiments, after the clamping part 110 clamps the filament, it maintains the clamping of the filament, and a part of the filament protrudes from the upper end of the clamping part 110. The protruding filament penetrates into the guiding channel 211. During the downward movement of the lamp head, it will land on the clamping part 110. Subsequently, the clamping driving part 120 drives the clamping part 110 to release the filament, so that the lamp head falls onto the bulb shell 820.

[0052] In some other embodiments, after the clamping part 110 clamps the filament, it maintains the clamping of the filament, and a part of the filament protrudes from the upper end of the clamping part 110. The clamping driving part 120 drives the clamping part 110 to release the filament, and then moves the lamp head downward so that the lamp head falls onto the bulb 820.

[0053] It should be understood that the outer diameter of the guiding part 210 is larger than the size of the through hole of the lamp head to ensure that the guiding part 210 can pass through the lamp head, and the inner diameter of the guiding channel 211 is larger than the size of the filament to ensure that the filament can still enter the guiding channel 211 when it is deflected by a certain angle.

[0054] Referring to Figure 1 and Figure 6 , according to some embodiments of the present application, the clamping part 110 includes a first clamping block 111 and a second clamping block 112. The clamping driving part 120 drives and connects one or both of the first clamping block 111 and the second clamping block 112 to make the first clamping block 111 and the second clamping block 112 approach or separate from each other; a guiding groove 1111 extending longitudinally is formed on the first clamping block 111, and a guiding structure 1121 is arranged on the side of the second clamping block 112 facing the first clamping block 111, and the guiding structure 1121 can be clamped into the guiding groove 1111.

[0055] It can be understood that during the process of guiding the filament, the filament is located between the first clamping block 111 and the second clamping block 112. The clamping driving part 120 drives one or both of the first clamping block 111 and the second clamping block 112 to make the first clamping block 111 and the second clamping block 112 approach each other. The guiding structure 1121 cooperates with the guiding groove 1111 to push the filament and straighten the filament. The first clamping block 111 and the second clamping block 112 clamp the filament to limit the filament and keep the filament in a straightened state, avoiding the filament from rebounding or rebounding too much after the first clamping block 111 and the second clamping block 112 release the filament.

[0056] Specifically, the clamping driving part 120 includes a cylinder and drives the first clamping block 111 and the second clamping block 112 at the same time. Specifically, the horizontal cross-section of the guiding structure 1121 is triangular, and the shape of the guiding groove 1111 is adapted to the guiding structure 1121.

[0057] In some embodiments, in order to avoid the first clamping block 111 and the second clamping block 112 from damaging the filament, referring to Figure 6, on one side of the guiding structure 1121 facing the guiding groove 1111, a tip 1122 is formed, and a notch 1112 is formed in the guiding groove 1111 corresponding to the tip 1122. The guiding structure 1121 is fitted into the guiding groove 1111 to push the filament into the notch 1112 of the guiding groove 1111. The tip 1122 of the guiding structure 1121 is inserted into the notch 1112 to cooperate with the notch 1112 to limit the filament, and there is a gap between the outer side of the tip 1122 and the inner wall of the notch 1112 that can accommodate the filament, thereby preventing the first clamping block 111 and the second clamping block 112 from damaging the filament. Specifically, the horizontal cross-section of the notch 1112 is substantially circular.

[0058] Referring to Figure 5 and Figure 6 , according to some embodiments of the present application, a plurality of first inserts 1113 are provided on the first clamping block 111, and a plurality of second inserts 1123 are provided on the second clamping block 112. The plurality of first inserts 1113 and the plurality of second inserts 1123 are both spaced along the height direction. The first inserts 1113 and the second inserts 1123 are staggered in the height direction. The first insert 1113 can be inserted between two adjacent second inserts 1123, and the second insert 1123 can be inserted between two adjacent first inserts 1113.

[0059] It can be understood that during the process of the first clamping block 111 and the second clamping block 112 approaching each other, the first insert 1113 can be inserted between two adjacent second inserts 1123. At the same time, the second insert 1123 is inserted between two adjacent first inserts 1113 to guide the action of the first clamping block 111 and the second clamping block 112 approaching each other, so that the first clamping block 111 and the second clamping block 112 are stably clamped.

[0060] In some embodiments, a guiding groove 1111 is formed on the first insert 1113.

[0061] Referring to Figure 5 and Figure 6 , according to some embodiments of the present application, the first clamping block 111 is provided with a first recess 1114 below the guiding groove 1111, and the second clamping block 112 is provided with a second recess 1124 below the guiding structure 1121. When the first clamping block 111 and the second clamping block 112 are joined, the first recess 1114 and the second recess 1124 form a second limiting channel for restricting the bulb 820.

[0062] It can be understood that after the first clamping block 111 and the second clamping part 110 approach each other and are joined, the first recess 1114 and the second recess 1124 will merge to communicate the second limiting channel. Among them, the upper end of the bulb 820 will be located in the second limiting channel to limit the bulb 820.

[0063] Figure 1 and Figure 2 and Figure 4 , according to some embodiments of the present application, it further includes a loading guide rail 410 for conveying lamp holders, and a loading driving part 320 for driving the loading part 310 to approach the loading guide rail 410 so that the loading part 310 clamps the lamp holder output from the discharge port of the loading guide rail 410.

[0064] It can be understood that the loading guide rail 410 is used to convey lamp holders, and the lamp holders are arranged along the conveying direction of the loading guide rail 410. The lamp holders on the loading guide rail 410 are output one by one from the discharge port of the loading guide rail 410. The loading driving part 320 can drive the loading part 310 to approach the loading guide rail 410 to clamp the lamp holder output from the discharge port of the loading guide rail 410.

[0065] Figures 2 to 5 , according to some embodiments of the present application, it further includes a limiting part 510, a pusher part 610 and a pusher driving part 620. The limiting part 510 is located on the moving path of the loading part 310. The limiting part 510 is provided with a limiting groove 511 which communicates with the output port of the loading guide rail 410. A pusher hole 512 is opened at the bottom of the limiting groove 511. The pusher part 610 is located below the limiting part 510 and corresponds to the pusher hole 512. The pusher driving part 620 is drivingly connected to the pusher part 610 for lifting to enable the pusher part 610 to pass through the pusher hole 512.

[0066] It can be understood that the lamp holder output from the discharge port of the loading guide rail 410 will enter the limiting groove 511 of the limiting part 510. In this embodiment, the limiting groove 511 only accommodates one lamp holder. After one lamp holder is accommodated in the limiting groove 511, the pusher driving part 620 drives the pusher part 610 to rise. The pusher part 610 passes through the pusher hole 512 and contacts the lamp holder in the limiting groove 511 to lift the lamp holder in the limiting groove 511. The loading driving part 320 drives the loading part 310 to approach the limiting part 510 to clamp the lamp holder lifted by the pusher part 610, so as to separate the first lamp holder and the second lamp holder, which is beneficial for the loading part 310 to clamp the lamp holder and avoid misclamping the second lamp holder.

[0067] In other embodiments, the limiting groove 511 can also accommodate multiple lamp holders, the pusher part 610 pushes multiple lamp holders at the same time, and the loading part 310 clamps multiple lamp holders at a time.

[0068] Figures 2 to 5 , according to some embodiments of the present application, it further includes a material separating part 710 and a material separating driving part 720. The material separating driving part 720 is drivingly connected to the material separating part 710 for enabling the material separating part 710 to enter or leave the loading guide rail 410.

[0069] It can be understood that after a lamp holder is accommodated in the limiting groove 511 of the limiting part 510, the material distributing driving part 720 drives the material distributing part 710 into the feeding guide rail 410. The material distributing part 710 abuts against the second lamp holder or blocks in front of the second lamp holder to limit the further forward movement of the second lamp holder, further separating the first lamp holder and the second lamp holder, and making the process of the ejecting part 610 ejecting materials stable. It should be understood that if the first lamp holder and the second lamp holder are in contact, when the ejecting part 610 lifts the first lamp holder, due to the frictional force between the first lamp holder and the second lamp holder, the second lamp holder also has an upward tendency. By abutting the material distributing part 710 against the second lamp holder, the upward movement of the second lamp holder is restricted, thereby avoiding the first lamp holder driving the second lamp holder to move upward, resulting in the second lamp holder flipping and dropping.

[0070] According to some embodiments of the present application, it further includes a vibrating disk (not shown in the figure), and the vibrating disk is communicated with the feeding port of the feeding guide rail 410.

[0071] It can be understood that a plurality of lamp holders placed disorderly are stored in the vibrating disk, and the vibrating disk outputs the disorderly lamp holders to the feeding guide rail 410 one by one.

[0072] Referring to Figure 2 and Figure 3 , according to some embodiments of the present application, a retaining rod 420 is arranged above the feeding guide rail 410, and the retaining rod 420 extends above the discharging port of the feeding guide rail 410.

[0073] It can be understood that the retaining rod 420 is located above the feeding guide rail 410 to limit the movement of the lamp holder and prevent the lamp holder from turning over and falling from the feeding guide rail 410. Moreover, the retaining rod 420 extends above the discharging port of the guide rail to limit the upward movement of the second lamp holder. Thus, even when the first lamp holder and the second lamp holder are in contact, when the first lamp holder is lifted by the ejecting part 610, the frictional force between the first lamp holder and the second lamp holder will make the second lamp holder have an upward tendency. Under the limiting effect of the retaining rod 420, the second lamp holder will not move upward with the first lamp holder, thereby further preventing the second lamp holder from flipping or dropping.

[0074] Referring to Figure 2 and Figure 4 , according to some embodiments of the present application, the feeding driving part 320 includes a translation driving assembly 321 and a lifting driving assembly 322. The feeding part 310 is arranged at the driving end of the translation driving assembly 321, and the translation driving assembly 321 is arranged at the driving end of the lifting driving assembly 322.

[0075] It can be understood that the limiting part 510 and the clamping part 110 are distributed in the horizontal direction. The translation driving assembly 321 drives the feeding part 310 to move above the limiting part 510, and then the lifting driving assembly 322 drives the feeding part 310 to descend so that the feeding part 310 can clamp the lamp holder lifted at the limiting part 510. Subsequently, the lifting driving assembly 322 drives the feeding part 310 to rise to a certain height, aligning the lamp holder grasped by the feeding part 310 between the guiding part 210 and the clamping part 110, and the translation driving assembly 321 drives the feeding part 310 to translate between the guiding part 210 and the clamping part 110.

[0076] Specifically, the feeding part 310 is a two-finger gripper.

[0077] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present application within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
