Description

Technical Field

[0001] The invention relates to the technical field of automated assembly, and in particular to a rotary table type automated assembly line for assembling reading lamps. Background Art

[0002] With the advancement of science and technology and the increase in labor costs, more and more factories have introduced automated assembly equipment, which can not only effectively reduce labor costs, but also effectively improve assembly quality and efficiency.

[0003] With regard to the existing automatic assembly lines for reading lights, due to structural design issues, although the reading lights can be automatically assembled, they cannot be inspected at the same time. As a result, after the reading lights are assembled and off the line, they must be transported and subjected to a separate inspection process. This not only affects the overall production efficiency, but also requires separate reading light inspection equipment, which takes up space and has a higher cost.

[0004] In addition, after the inspection, the reading lights need to be classified into qualified and defective products and taken offline, and usually the defective products are classified and recycled according to the reasons for the defects. However, due to the structural design problems of the existing equipment, the offline robot must first grab the reading light and send it to the barcode scanning device for scanning to identify whether it is a qualified product. If it is a defective product, the unqualified reading light is transferred to the corresponding defective product collection box according to the read reason for the defect. Therefore, when the offline robot takes off qualified products, the distance from the qualified product offline assembly is constant and the beat is stable; when the offline robot takes off defective products, the time taken varies depending on the distance to the defective product collection box, and the beat is fast or slow, which greatly affects the overall beat.

[0005] Solving the above problems has become a top priority. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a turntable type automatic assembly line for assembling reading lamps.

[0007] The technical solution is as follows:

[0008] A turntable automatic assembly line for assembling reading lights, comprising a base and a turntable mounted on the top of the base, characterized in that: the base is provided with a waiting station, a loading station, a screwing station, a detection and coding station, a flipping station, an electrical inspection station, a visual inspection station and a PIN needle inspection station which are sequentially distributed in a ring shape around the turntable;

[0009] The loading station is provided with a loading mechanism for transferring the reading lamp to be assembled to the turntable and a material detection mechanism for detecting whether there is a reading lamp to be assembled on the loading mechanism;

[0010] The screw driving station is provided with a screw driving mechanism for driving screws into the reading light;

[0011] The detection and coding station is provided with a first PIN pin detection mechanism for detecting whether the PIN pin of the reading light is intact and a coding mechanism for coding the reading light;

[0012] The flipping station is provided with a flipping mechanism for flipping the reading light;

[0013] The electrical inspection station is provided with a first electrical inspection plug-in mechanism for supplying power to and communicating with the reading light and a touch mechanism for touching the reading light button;

[0014] The visual inspection station is provided with a second electrical inspection plug-in mechanism for supplying power to and communicating with the reading lamp, and a visual inspection mechanism for detecting whether the brightness and grayscale of the reading lamp are qualified;

[0015] The PIN pin detection station is provided with a second PIN pin detection mechanism for detecting whether the PIN pin of the reading light is intact;

[0016] The rotary table automatic assembly line for assembling reading lamps also includes a classification offline mechanism, which includes an offline robot, a code scanning device, a qualified product offline component and a defective product recovery component arranged between the visual inspection mechanism and the second PIN needle inspection mechanism, and the offline robot is used to grab the reading lamps inspected by the second PIN needle inspection mechanism to the code scanning device for scanning and identification, and transfer qualified reading lamps to the qualified product offline component and transfer unqualified reading lamps to the defective product recovery component;

[0017] The defective product recovery component includes a defective product channel, a classification transfer module and a classification collection module installed on the base from top to bottom in sequence. The classification collection module includes a plurality of defective product collection boxes installed side by side in the horizontal direction on the base. The classification transfer module is used to transfer the workpieces transported from the defective product channel to the corresponding defective product collection box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The turntable automatic assembly line for assembling reading lights that adopts the above technical solution has a novel structure, ingenious design, and a high degree of automation. It can not only automatically assemble reading lights, but also perform PIN needle detection, touch detection, communication detection, lighting angle detection, and PIN needle detection on reading lights before electrical inspection. Qualified products can be directly taken offline, and unqualified products can be directly recycled, thereby realizing the integration of reading light assembly and detection with a very high degree of integration. It is no longer necessary to perform post-assembly inspection separately, which not only reduces space occupancy but also reduces costs. In addition, by designing a new defective product recovery component, the unqualified reading lights transported from the defective product channel are transferred to the corresponding defective product collection box through the classification and transfer module, so that the offline robot transfers the reading lights to the qualified product offline component or defective product channel at a fixed position when taking off qualified reading lights or unqualified reading lights, and the rhythm is very stable, which not only eliminates the impact on the overall rhythm of the turntable automatic assembly line for assembling reading lights, but also improves the overall efficiency of the turntable automatic assembly line for assembling reading lights by improving the offline efficiency.

Then the visual inspection mechanism 16 detects whether the brightness and grayscale of the reading light A are qualified. After completion, the turntable 2 rotates to transfer the reading light A to be assembled to the PIN needle inspection station. The second PIN needle inspection mechanism 17 detects whether the PIN needle of the reading light A is intact. After completion, the offline robot 3 grabs the reading light A and gives it to the code scanning device 4 for scanning and identification. When the reading light A is read as a qualified product, the qualified reading light A is transferred to the qualified product offline component 5. When the reading light A is read as a defective product, the unqualified reading light A is transferred to the defective product recovery component 6.

[0052] Therefore, by designing a new defective product recovery component 6, the reading light A transported from the defective product channel is transferred to the corresponding defective product collection box 6c1 through the classification and transfer module 6b, so that the offline robot 3 can transfer the reading light A to a fixed position regardless of whether it is a qualified reading light A or an unqualified reading light A. That is, the qualified reading light A is transferred to the qualified product offline component 5, and the unqualified reading light A is transferred to the defective product channel 6a. The distances are fixed, so the rhythm is very stable, which not only eliminates the impact on the overall rhythm of the turntable automatic assembly line for assembling reading lights, but also improves the overall assembly efficiency of the turntable automatic assembly line for assembling reading lights by improving the offline efficiency.

[0053] The qualified product offline assembly 5 includes a conveyor belt bracket 5a installed on the base 1 and an electric conveyor belt 5b installed on the conveyor belt bracket 5a. The offline assembly 5 is stable, reliable and efficient. In addition, in this embodiment, the feeding end of the electric conveyor belt 5b and the defective product channel 6a are respectively located on both sides of the code scanning device 4, so that the distance between the offline manipulator 3 transferring the qualified reading lamp A and the unqualified reading lamp A can be controlled to be the same, thereby further improving the stability of the beat.

That is: the offline manipulator 3 throws the unqualified reading lamp A into the defective product channel 6a, and the unqualified reading lamp A finally falls out of the first drop hole 1b1 and is caught by the classification and transfer module 6b, and then transferred to the corresponding defective product collection box 6c1 by the classification and transfer module 6b, which is stable, reliable and easy to implement.

[0055] See also Fig.11 and Fig.12 The classification transfer module 6b includes a transfer module upper mounting plate 6b1 fixedly mounted on the lower surface of the equipment mounting platform 1b, a first slide rail 6b2 fixedly mounted on the lower surface of the transfer module upper mounting plate 6b1 along the arrangement direction of each defective product collection box 6c1, a transfer module lower mounting plate 6b3 fixedly mounted on the slide of the first slide rail 6b2, a screw rod 6b4 parallel to the first slide rail 6b2, a screw motor 6b5 for driving the screw rod 6b4 to rotate, and a screw nut 6b6 forming a screw nut kinematic pair with the screw rod 6b4, the screw motor 6b5 is fixedly mounted on the transfer module upper mounting plate 6b1, and the screw nut 6b6 is screwed to the lower surface of the transfer module upper mounting plate 6b1. The female connecting seat 6b7 is fixedly connected to the lower mounting plate 6b3 of the transfer module. A second blanking hole 6b31 is provided on the lower mounting plate 6b3 of the transfer module. A receiving cylinder 6b8 located on the upper part of the second blanking hole 6b31 is vertically installed on the upper surface of the lower mounting plate 6b3 of the transfer module. A blanking hole opening and closing kit 6b9 for opening or covering the second blanking hole 6b31 is installed on the lower surface of the lower mounting plate 6b3 of the transfer module. Through the forward and reverse control of the screw motor 6b5, the receiving cylinder 6b8 can be located directly below the first blanking hole 1b1, and the second blanking hole 6b31 can be moved back and forth above each defective product collection box 6c1.

[0056] The motor shaft of the screw motor 6b5 drives the screw 6b4 to rotate, so that the screw nut 6b6 drives the lower mounting plate 6b3 of the transfer module to translate along the arrangement direction of each defective product collection box 6c1 through the nut connecting seat 6b7 (slides back and forth on the first slide rail 6b2). When in place, the unqualified reading light A can be controlled by the blanking hole opening and closing kit 6b9 to fall from the second blanking hole 6b31 into the corresponding defective product collection box 6c1.

In addition, a limiting bracket 6b71 is installed on one side of the nut connecting seat 6b7, and two maximum displacement limiting seats 6b11 adapted to the limiting bracket 6b71 are installed on the upper mounting plate 6b1 of the transfer module. Through the cooperation of the limiting bracket 6b71 and the two maximum displacement limiting seats 6b11, the maximum displacement of the nut connecting seat 6b7 in two directions can be limited, which is simple and reliable.

[0059] By pulling or pushing the cylinder connecting block 6b94 through the piston rod of the baffle driving cylinder 6b92, the workpiece baffle 6b93 can be driven to slide back and forth on the second slide rail 6b91, so that the workpiece baffle 6b93 can be controlled to open or block the second blanking hole 6b31. When the workpiece baffle 6b93 blocks the second blanking hole 6b31, the unqualified reading light A that falls into the defective product collection box 6c1 is placed on the workpiece baffle 6b93, so that it can be transferred; when the blanking hole opening and closing kit 6b9 moves to the set position, the workpiece baffle 6b93 is opened, and the unqualified reading light A falls from the second blanking hole 6b31 into the corresponding defective product collection box 6c1.

[0060] See also Fig.13 The defective product collection box 6c1 is provided with an openable and closable access door 6c11 on one side of the side plate adjacent to the bottom cabinet 1a, so as to facilitate the access of the defective reading lamp A. In addition, the access door 6c11 is provided with a door opening hole 6c12 for hand picking, so that a door handle does not need to be installed, thus saving costs.
