[0024] A bolt feed guide hole is provided on one side of the transition cavity. The end of the bolt feed guide hole away from the transition cavity is connected to a guide pipe joint. The guide pipe joint is connected to the bolt feeder through the bolt guide pipe.

[0025] The mounting base is equipped with a clamping cylinder, a pressure plate is connected to the clamping cylinder, and a pressure rod is connected to the pressure plate; when installing bolts, the clamping cylinder drives the pressure rod to move down and presses the T-shaped mounting bracket placed on the tooling downward.

[0026] Preferably, the unloading station is equipped with an unloading conveyor belt and an unloading robot, with the unloading robot located on one side of the unloading conveyor belt and equipped with a third clamping component.

[0027] The automatic assembly method for lamp holders includes the following specific steps:

[0028] Step 1: The turntable rotates, moving the fixture to the bracket connector installation position. The first drive unit drives the moving block to the receiving position. At this time, the bearing groove on the moving block is located below the discharge end of the first feeding guide rail. The bracket connector located at the end of the first feeding guide rail falls into the bearing groove on the moving block. After the bearing groove receives the material, the first drive unit drives the moving block to the discharge position. The first robot arm drives the first clamping component to move above the bearing groove. The first clamping component grabs the bracket connector from the bearing groove, and then the first robot arm puts the grabbed bracket connector into the bracket connector positioning groove on the fixture.

[0029] Step 2: The turntable rotates, moving the fixture to the gasket installation station. The second robotic arm picks up a gasket from the discharge position of the gasket feeder. When picking up the gasket, the lower end of the core rod extends out of the lower end face and inserts into the inner hole of the gasket, with the steel ball pressing against the inner wall of the gasket. Then, the second robotic arm moves the picked-up gasket to above the gasket positioning groove on the fixture and then removes the gasket. When removing the gasket, the second drive unit drives the gripping end of the core rod to move upward and retract into the sleeve, and the gasket falls into the gasket positioning groove on the fixture.

[0030] Step 3: The turntable rotates, moving the fixture to the T-shaped mounting bracket installation position. The T-shaped mounting brackets are stored in the second vibrating plate. The T-shaped mounting brackets are discharged one by one from the second vibrating plate and move along the second feeding guide under the action of the vibration device. The T-shaped mounting brackets located at the end of the second feeding guide enter the T-shaped mounting bracket positioning slot on the material positioning block. The third robot arm drives the second clamping component to move to the position of the material positioning block and grabs the T-shaped mounting bracket from the material positioning block. Then, the third robot arm places the grabbed T-shaped mounting brackets onto the fixture. When the T-shaped mounting brackets are placed on the fixture, the first bracket end of the T-shaped mounting bracket is placed in the first bracket end positioning slot, and the second bracket end of the T-shaped mounting bracket is placed in the second bracket end positioning slot.

[0031] Step 4: The turntable rotates, moving the fixture to the bolt installation position. The clamping cylinder drives the pressure rod downward, pressing the T-shaped mounting bracket placed on the fixture downward. Bolts from the bolt feeder enter the bolt chuck body one by one through the bolt guide tube. After passing through the bolt feed guide hole and transition cavity, the bolts reach the bolt clamping port at the lower end of the bolt clamping arm. The bolt head is clamped between the clamping ends at the lower end of the bolt clamping arm, and the stud on the bolt passes downward through the bolt clamping port. Then, the third drive unit drives the bolt chuck body and the bolt to descend, so that the lower end of the bolt passes through the bolt through hole and washer on the T-shaped mounting bracket.

[0032] Subsequently, the third drive unit drives the motor and screwdriver rod to descend. The screwdriver head at the lower end of the screwdriver rod extends into the groove on the bolt head and pushes the bolt downward. At the same time, the motor drives the screwdriver rod to rotate, which in turn drives the bolt to rotate and screws the bolt into the bolt hole on the bracket connector. After the bolt is tightened, the bolt chuck body and screwdriver rod rise to return to their original positions.

[0033] Step 5: The turntable rotates, moving the fixture to the unloading station, and the assembled lamp bracket is removed from the fixture.

[0034] The beneficial effects of this invention are: this invention enables automated assembly of lamp holders, and the entire assembly process requires no manual intervention, which has the following advantages:

[0035] 1. Effectively reduces labor costs, thereby reducing the production cost of a single lamp holder;

[0036] 2. Automated assembly methods greatly improve assembly efficiency, thereby increasing production capacity;

[0037] 3. Since no manual assembly is required, the cost of training workers is saved;

[0038] 4. The use of mechanized assembly methods ensures the stability of product assembly quality. Attached Figure Description

The bracket connector 11 located at the end of the first feeding guide rail 52 falls into the bearing groove 58 on the moving block 56. After the bearing groove 58 receives the material, the first drive unit 57 drives the moving block 56 to move to the discharge position. The first robot arm 53 drives the first clamping component 59 to move above the bearing groove 58. The first clamping component 59 grabs the bracket connector 11 from the bearing groove 58. Then, the first robot arm 53 puts the grabbed bracket connector 11 into the bracket connector positioning groove 41 on the tooling 4.

[0085] Step 2: The turntable 3 rotates, driving the tooling 4 to move to the gasket installation station. The second robotic arm 62 grabs a gasket 12 from the discharge position on the gasket feeder 61. When grabbing the gasket 12, the lower end of the core rod 67 extends out of the lower end face 68 and inserts into the inner hole of the gasket 12. The steel ball 610 presses against the inner wall of the gasket 12. Then, the second robotic arm 62 moves the grabbed gasket 12 to above the gasket positioning groove 44 on the tooling 4, and then removes the gasket 12. When removing the gasket 12, the second driving member 65 drives the gripping end of the core rod 67 to move upward and retract into the sleeve 66, and the gasket 12 falls into the gasket positioning groove 44 on the tooling 4.

[0086] Step 3: The turntable 3 rotates, driving the tooling 4 to move to the T-shaped mounting bracket installation position. The T-shaped mounting bracket 13 is stored in the second vibrating plate 71. The T-shaped mounting bracket 13 is discharged one by one from the second vibrating plate 71 and moves along the second feeding guide rail 72 under the action of the vibration device 75. The T-shaped mounting bracket 13 located at the end of the second feeding guide rail 72 enters the T-shaped mounting bracket 13 positioning groove on the material positioning block 73. The third robot arm 76 drives the second clamping component 77 to move to the position of the material positioning block 73 and grabs the T-shaped mounting bracket 13 from the material positioning block 73. Then, the third robot arm 76 places the grabbed T-shaped mounting bracket 13 onto the tooling 4. When the T-shaped mounting bracket 13 is placed on the tooling 4, the first bracket end 15 of the T-shaped mounting bracket 13 is placed in the first bracket end positioning groove 42, and the second bracket end 17 of the T-shaped mounting bracket 13 is placed in the second bracket end positioning groove 43.

[0087] Step 4: The turntable 3 rotates, driving the fixture 4 to move to the bolt installation position. The clamping cylinder 814 drives the pressure rod 816 to move down and press the T-shaped mounting bracket 13 placed on the fixture 4 downward. The bolts 14 in the bolt feeder 81 enter the bolt 14 chuck body one by one through the bolt 14 guide tube. The bolts 14 pass through the bolt feed guide hole 823 and the transition cavity 822 in sequence and reach the bolt 14 clamping port at the lower end of the bolt clamping arm 817. The bolt head on the bolt 14 is clamped between the clamping end 818 at the lower end of the bolt clamping arm 817. The stud on the bolt 14 passes downward through the bolt 14 clamping port. Then the third driving component 85 drives the bolt 14 chuck body and the bolt 14 to descend, so that the lower end of the bolt 14 passes through the bolt through hole 16 and the washer 12 on the T-shaped mounting bracket 13.

[0088] Subsequently, the third drive unit 85 drives the motor 89 and the screwdriver rod 810 to descend. The screwdriver head at the lower end of the screwdriver rod 810 extends into the groove on the bolt head and pushes the bolt 14 downward. At the same time, the motor 89 drives the screwdriver rod 810 to rotate, and the screwdriver rod 810 drives the bolt 14 to rotate, screwing the bolt 14 into the bolt hole 18 on the bracket connector 11. After the bolt 14 is tightened, the bolt 14 chuck body and the screwdriver rod 810 rise and return to their original positions.

[0089] Step 5: The turntable 3 rotates and drives the tooling 4 to the unloading station. The unloading robot 91 removes the assembled lamp bracket 1 from the tooling 4. The removed lamp bracket 1 is placed on the unloading conveyor belt 93, and the unloading conveyor belt 93 realizes the output of the lamp bracket 1.

[0090] This invention enables automated assembly of the lamp holder 1, eliminating the need for manual intervention throughout the assembly process, and offers the following advantages:

[0091] 1. Effectively reduces labor costs, thereby reducing the production cost of a single lamp holder 1;

[0092] 2. Automated assembly methods greatly improve assembly efficiency, thereby increasing production capacity;

[0093] 3. Since no manual assembly is required, the cost of training workers is saved;

[0094] 4. The use of mechanized assembly methods ensures the stability of product assembly quality.

[0095] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
