DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0043] The present embodiment provides an automatic assembly method of LED ceiling lamp, which comprises a conveying line 1 and a jig 11 located on the conveying line 1. The jig 11 is provided with a lamp cup 12. The jig 11 moves along with the conveying line 1. The jig 11 is provided with two placing grooves, and the lamp cup 12 is placed in the placing grooves with the opening upward. The assembly process of the LED ceiling lamp is as follows:

[0044] S1, lamp pin correction: two sides of the conveying line are symmetrically provided with correction mechanisms 2, the correction mechanisms 2 include shaping fixed ends 21 and driving members for driving the shaping fixed ends to reciprocate, the driving members drive the shaping fixed ends 21 to move towards the direction of approaching the jig 11, and the two shaping fixed ends 21 simultaneously abut against the two sides of the jig 11;

[0045] The two sides of the jig are provided with positioning surfaces 10, and the end surfaces of the two shaping fixed ends 21 abut against the two positioning surfaces 10 to correct the jig 11 in the horizontal direction.

[0046] S2, lamp cup pressing 3: the conveying line is provided with a pressing rod 31, when the jig 11 moves to the lower side of the pressing rod 31, the pressing rod 31 moves downward to abut against the inner wall of the lamp cup 12;

[0047] The bottom of the pressing rod 31 is in shape fit with the bottom of the lamp cup 12, and the pressing rod 31 is pressed downward into the lamp cup 12 to make the lamp cup 12 and the jig 11 fully contact.

[0048] S3, lamp filament installation 4: the lamp filament roll winding the lamp filament is fixed at the top of the lamp filament straightening mechanism, the lamp filament is conveyed from top to bottom through two groups of rollers, and the two ends of the lamp filament are stretched and straightened through the two groups of rollers (the lower roller provides downward tension, and the upper roller provides certain resistance, so that the lamp filament has downward stretching force, and the lamp filament is straightened through the stretching force); the lamp filament enters the lamp filament processing mechanism through the wire feeding mechanism, the lower pushing cylinder drives the lamp filament processing mechanism to move downward, the bottom of the lamp filament is bent through the stamping of the pressing blocks on the two sides (the pressing blocks are two surface-embedded curved blocks, the lamp filament is pressed in the curved surfaces of the two curved blocks through the movement of one of the pressing blocks, so that the lamp filament is bent), the bottom end of the lamp filament is clamped through the two clamping blocks, the cutting block at the top of the lamp filament processing mechanism cuts the lamp filament (the principle of the cutting block is the same as that of a pair of scissors), the lower pushing cylinder drives the lamp filament processing mechanism to move upward and reset; the clamping block moves horizontally to make the cut lamp filament below the conveying micro gripper 42, the micro gripper 42 clamps the lamp filament, the clamping block releases the lamp filament, the micro gripper 42 clamps the lamp filament and takes it down, the micro gripper 42 moves to the inside of the lamp cup 12, the small cylinder at the bottom of the jig 11 lifts the lamp cup 12 by a small distance, but cannot make the lamp cup 12 separate from the placing groove, so that the lamp filament enters the lamp pin 14 at the bottom of the lamp cup 12, the stamping pins 43 and the stamping plate 44 on the two sides stamp the lamp pin 14, so that the lamp pin 14 is deformed, and the lamp filament is pressed in the lamp pin 14, and the lamp filament and the lamp pin 14 are combined into one.

[0049] It is worth noting that two lamp filaments are installed in each lamp cup 12, and two lamp pins 14, the straightening, bending and cutting of the lamp filament are simultaneously performed by two groups of symmetrical lamp filament processing mechanisms 41 to form two lamp filaments; and two lamp cups 12 are installed on one jig 11, so two groups of lamp filament installation 4 are arranged to install the lamp filaments for the two lamp cups 12.

[0050] The filament processing mechanism 41 is a prior art, which is used to straighten the filament by two groups of rollers, and then to press the filament into a required shape by extrusion, and finally to cut the bent filament and deliver it to the micro gripper 42.

[0051] S4, lamp plate installation 9: the lamp plate clamp 91 clamps the lamp plate 13, the lamp plate clamp 91 moves to the top of the lamp cup 13, the two filament clamping plates 92 clamp the top end of the filament and play a positioning role on the filament, so that when the lamp plate clamp 91 clamps the lamp plate 13 and moves to the filament clamping plate 92, the filament is just aligned with the downward horn opening 131 on the lamp plate 13, at this time the filament is loosened, the lamp plate 13 is placed on the lamp cup 12, and the filament enters along the horn opening 131;

[0052] The filament clamping plate 92 clamps the filament, which better solves the problem of flexible filament not easy to align and improves the production precision of the LED ceiling lamp.

[0053] S5, lamp plate pressing 5: the lamp plate pressing cylinder pushes the pressing gripper to descend and press the lamp plate 13;

[0054] The lamp plate pressing 5 includes a preliminary lamp plate pressing 51 and a lamp plate pressing in place 52,

[0055] S501, preliminary lamp plate pressing 51: the three first pressing grippers 52 of the same height descend and abut on the lamp plate 13, and the lamp plate 13 is preliminarily pressed;

[0056] S502, lamp plate pressing in place 52: the second pressing grippers 54 press the lamp plate 13, and the lamp plate 13 is pressed and descended on the lamp cup 12;

[0057] In the lamp plate 13 pressing tooling at the S501 station, the lamp plate 13 only preliminarily allows the filament to enter the inside of the lamp plate 13, and since the filament is relatively soft, if it is pressed too hard, the filament will be deformed and twisted, at this time the lamp plate 13 has not yet been attached to the stepped fixed surface in the lamp cup 12, and needs to be completely pressed in place in the lamp plate pressing station S502, the filament is clamped by the pressing plate 55 at this time, and then the lamp plate 13 is pressed, the filament will not be deformed and twisted, and this step is to evenly distribute the pressure on the lamp plate; the filament is clamped by the pressing plate 55, and then the lamp plate 13 is pressed, which overcomes the flexible deformation of the filament.

[0058] S6, filament shearing 6: the thumb air cylinder drives the shearing moving block 61 to move horizontally, and realizes shearing action with the shearing fixed block 62, and the excess filament is sheared; the shearing fixed block 62 is provided with an opening 621, the excess filament is made to pass through the opening 621 by moving the shearing fixed block 62 and the shearing moving block 61 as a whole, the thumb air cylinder drives the shearing moving block 61 to move horizontally, and the filament above the opening 621 is sheared (the openings 621 of the two shearing fixed blocks 62 face away from each other), and the excess filament is retained on the shearing fixed block 62, when the shearing fixed block 62 and the shearing moving block 61 move as a whole to the outside of the lamp cup 12, the sheared excess filament is removed again, so that the filament is prevented from falling into the lamp cup 12 and short-circuiting after being electrified.

[0059] S7, gluing 7: when the lamp cup 12 moves to the bottom of the gluing device, the needle cylinder 71 filled with glue drips glue on the lamp plate 13, the needle cylinder 71 is filled with glue in advance, and the glue is coated on the lamp plate 13 by increasing the pressure.

[0060] S8, installing lampshade 8: a plurality of circumferentially arranged C-shaped grooves 81 are provided with lampshades 14, the lampshades 14 are stacked together and placed, the lampshades 14 are pushed to the predetermined position by the push air cylinder, the lampshades 14 are sucked by the two suction cups 82, the lampshades 14 are sucked by negative pressure, the lampshades 14 are mounted on the lamp cup 13, and the lampshades 14 are pressed to be tightly pressed on the lamp cup 13.

[0061] The application realizes machine instead of human, reduces labor cost, and greatly improves production efficiency, and the time period of each link work is 3-4 seconds, so that high efficiency and high yield are realized.

[0062] It will be obvious to a person skilled in the art that the application is not limited to the details of the above-described exemplary embodiments, but that the application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. Therefore, the embodiments should be considered as exemplary and not limiting in any way, the scope of the application being defined by the claims appended hereto rather than by the above description, and all changes falling within the meaning and range of equivalency of the elements of the claims are therefore intended to be embraced therein.
