Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a secondary positioning device for the base of an automated LED lamp production line. Background Technology

[0002] The structure of commercially available LED desk lamps typically consists of a base, a vertical pole, and a horizontal bar. The vertical pole and horizontal bar are connected by a hinged joint. The vertical pole is mounted on the base, and the LED light panel is mounted on the horizontal bar. Due to the increasing automation of industrial production, LED desk lamp manufacturers are more inclined to transform traditional equipment into unmanned automated production lines. In the base assembly process of a fully automated production line, a robot needs to remove the base component from the feeding line and place it onto the carrier on the final assembly line to prepare for subsequent assembly processes. The base component consists of a top cover and a bottom box. When these two components enter the final assembly line from their respective feeding lines, if the robot directly picks up the components from the feeding line and clamps them onto the final assembly carrier using a three-axis servo system, the placement of the components on the feeding carrier is relatively spacious with large positional tolerances, while the positional tolerance of the bottom box on the final assembly carrier is very small. This results in a large deviation in the robot's travel path. Therefore, the requirements for the robot are relatively high, and it usually needs to be equipped with a vision recognition system, which increases the overall cost. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a secondary positioning device for the base of an automated LED lamp production line, which assists the robot in moving the base from the feeding line to the final assembly line, reducing the control difficulty of the robot, thereby reducing the total cost of the equipment and overcoming the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A secondary positioning device for the base of an automated LED lamp production line includes a feeding line, a final assembly line, a three-axis servo system, and a gripping robot mounted thereon. The gripping robot transfers base components from the feeding line to a final assembly carrier on the final assembly line. The final assembly line is mounted on a first frame. The device is characterized by a second frame located next to the first frame, on which a first positioning device is mounted. The first positioning device includes a positioning seat and two positioning cylinders. The positioning seat has a right-angle stop. The gripping robot picks up the base component from the feeding line and places it within the first positioning device. The positioning cylinders push the base component against the right-angle stop, and then the gripping robot picks up the base component from the first positioning device and transfers it to the final assembly carrier.

[0006] The feeding line and the final assembly line are arranged perpendicular to each other. A dust removal device is also installed on the second frame. The dust removal device includes a dust collection box, an air duct, and a blower. An air outlet is provided on the side wall of the air duct. Air is blown out from the air outlet of the air duct by the blower to remove dust from the base accessories in the dust collection box.

[0007] The assembly line is equipped with a blocking cylinder mechanism corresponding to the position of the second frame. The blocking cylinder mechanism includes a fixed frame, a baffle, a blocking cylinder, and a sensor. The blocking cylinder drives the baffle to move vertically up and down. When the assembly carrier moves with the assembly line and touches the raised baffle, the sensor sends a signal to the PLC controller of the automated production line. The PLC controller drives the lifting mechanism to raise the assembly carrier, so that the assembly carrier is removed from the assembly line. At the same time, the PLC controller sends a signal to the three-axis servo system and the gripping robot. The gripping robot picks up the base part of the first positioning device, moves it to the dust collection box for a short stay, and then sends the base part to the raised assembly carrier. The base part stays in the dust collection box for 3 to 30 seconds.

[0008] The lifting mechanism includes a lifting plate, a lifting cylinder, and a mounting plate. The lifting cylinder is mounted on the mounting plate, and the shaft end of the output shaft of the lifting cylinder is connected to the lifting plate.

[0009] Guide columns are provided between the lifting plate and the mounting plate.

[0010] There are two air ducts, one on each side of the dust collection box.

[0011] The above technical solution has the following beneficial effects:

[0012] This invention adds a secondary positioning device between the feeding line and the final assembly line. After the lamp base components are taken from the feeding line, they are first initially positioned by the first positioning device to maintain consistency in their initial position. Then, a robot picks them up from the first positioning device and places them onto the carrier on the final assembly line for secondary positioning. This ensures that the LED lamp base components are in a precise processing position before final assembly, facilitating subsequent processing of the lamp base. It also eliminates the need for manual adjustments by workers during later processing, reducing labor intensity, improving production continuity, and increasing efficiency. Furthermore, the addition of the positioning device eliminates the need for a vision recognition device on the robot, reducing the overall cost of the production line. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] See Figures 1-6As shown, this utility model discloses a secondary positioning device for the base of an automated LED lamp production line, including a feeding line 5, a final assembly line 4, a three-axis servo system 3 and a gripping robot on it. The gripping robot moves the base parts from the feeding line to the final assembly carrier on the final assembly line. The final assembly line is mounted on a first frame 100, and a second frame 200 is set next to the first frame 100. A first positioning device 1 is set on the second frame, which includes a positioning seat 11 and two positioning cylinders 12. The gripping robot picks up the base parts from the feeding line and places them in the first positioning device. The cylinders 12 push the base parts against the right-angle stop. Then, the gripping robot picks up the base parts from the first positioning device and moves them to the final assembly carrier 7. The positioning seat 11 is provided with a right-angle stop 111, and the two positioning cylinders correspond to the two stops of the right-angle stop respectively. When the base parts (top cover or bottom box) are placed into the positioning seat, the PLC controller drives the two positioning cylinders to push the base parts against the right-angle stop, thus fixing the position of the base parts.

[0023] The feeding line and the final assembly line are arranged perpendicular to each other. A dust removal device 2 is also provided on the second frame. The dust removal device includes a dust collection box 21, an air duct 22, and a blower 23. An air outlet 221 is provided on the side wall of the air duct. Air is blown out from the air outlet of the air duct by the blower to remove dust from the base accessories in the dust collection box.

[0024] A blocking cylinder mechanism 6 is installed at the position corresponding to the second frame on the final assembly line. This mechanism includes a fixed frame 62, a baffle 61, a blocking cylinder 60, and a sensor. The blocking cylinder drives the baffle to move vertically up and down. When the final assembly carrier moves with the assembly line and touches the raised baffle, the sensor sends a signal to the PLC controller of the automated production line. The PLC controller then drives the lifting mechanism 8 to raise the final assembly carrier, causing it to detach from the assembly line. Simultaneously, the PLC controller sends signals to the three-axis servo system and the gripping robot. The gripping robot picks up the base component from the first positioning device, moves it to the dust collection box for a brief stop, and then places it onto the raised final assembly carrier. The base component stays in the dust collection box for 3 to 30 seconds. Two hydraulic buffers 63 are installed on the baffle. The baffle stops the carrier being transported to this location, while the hydraulic buffers provide stability. A sensor, a magnetic sensor, is mounted on the fixed frame via screws. During the carrier's movement, it encounters the hydraulic buffer on the baffle and stops. At this point, the carrier is positioned precisely at the processing work position. Simultaneously, the magnetic metal sheet on the bottom edge of the carrier contacts the magnetic sensor, which sends a signal to the PLC control center, which then issues a command. To ensure smoother sliding of the baffle, a groove is formed on the side wall of the baffle 61, within which a guide block 64 is installed. The guide block 64 is fixed to the fixed frame 62.

[0025] The lifting mechanism 8 includes a lifting plate 81, a lifting cylinder 83, and a mounting plate 82. The lifting cylinder is mounted on the mounting plate 82, and the output shaft of the lifting cylinder is connected to the lifting plate. A guide post 84 is provided between the lifting plate 81 and the mounting plate 82 to improve guidance and make the lifting plate rise and fall more smoothly.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
