Description

Technical Field

[0001] The present invention relates to a rotary labeling mechanism and a labeling method for an automatic offline labeling machine, belonging to the field of intelligent equipment. Background Art

[0002] Cables are an important part of aerospace electronic products and are the bridges connecting various instruments within or between systems. The automatic offline labeling machine is an automated production equipment in the cable blank processing process, mainly used in the production of large cable networks, aiming to improve the production efficiency of cable network products, solve the quality problems of cable network products, and comprehensively improve the manufacturing level of aerospace cable networks. In the existing labeling mechanisms, there are the following problems: they are relatively large in size and cannot effectively adsorb and label small labels; the label suction structure is generally a large flat plate structure with insufficient flatness, resulting in gaps after labeling, which are prone to aging and breakage; at the same time, the existing labeling mechanisms are generally semi-automatic devices and require human participation; in addition, the existing labeling mechanisms can only label one label at a time, and after labeling, they need to adsorb the label again to label again, with a large degree of repetition and low efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: overcoming the deficiencies of the prior art, a rotary labeling mechanism that can receive labels twice and simultaneously label wires with different wire diameters is proposed. After receiving the first label at a specified position, through a 180° rotation and appropriate displacement, the label receiving structure that has completed label suction and the label receiving structure that has not completed label suction are interchanged in position to complete the second label suction.

[0004] The technical solution of the present invention is:

[0005] A rotary labeling mechanism for an automatic offline labeling machine includes a label receiving structure, a labeling structure, a rotating structure, and a moving structure;

[0006] Labeling structures are symmetrically installed on two arms of the rotating structure, label receiving structures are installed on both labeling structures, and the two label receiving structures are in mirror positions. The rotating structure is installed on the moving structure; after the first label is received at a specified position, through a 180° rotation and appropriate displacement of the rotating structure, the label receiving structure that has completed label suction and the label receiving structure that has not completed label suction are interchanged in position to complete the second label suction; after the two label receptions are completed, the whole is moved under the wire by the moving structure to complete the labeling work of two labels for wires with different wire diameters at one time.

[0007] Further, after the labeling is completed, during the process of returning to the original position, the rotating structure rotates reversely to reset to the starting label receiving position to prepare for the next label receiving work.

[0008] Further, the label receiving structure includes a lower label receiving plate, an upper left label receiving plate, and an upper right label receiving plate; the lower label receiving plate is sealed with the upper left label receiving plate and the lower right label receiving plate respectively by laser welding to form a cavity inside; bosses are designed on the upper left label receiving plate and the lower right label receiving plate, and small holes of the same size are opened on the bosses for adsorbing labels.

[0009] Further, the labeling structure includes a rotating bottom plate, a sliding rail bottom plate, a guide rail, a mounting beam, a cylinder, an adjusting gasket, a fixing plate, a label receiving structure fixing plate, a pushing shaft, and a rotating shaft;

[0010] The cylinder is arranged below the rotating bottom plate, and the telescopic rod of the cylinder passes through the through hole provided on the rotating bottom plate and is fixedly connected to the mounting beam located above the rotating bottom plate. An adjusting gasket is sleeved on the telescopic rod above the rotating bottom plate; the sliding rail bottom plate is fixed on the rotating bottom plate, and the guide rail is fixed on the sliding rail bottom plate by screws and is in a vertical state. The mounting beam is fixed on the two sliding rails and can move up and down vertically on the sliding rails. The mounting beam is ensured to be horizontal during installation; the fixing plate is fixedly connected to one end of the rotating bottom plate, the rotating shaft is installed at the top of the fixing plate, the label receiving structure fixing plate is connected to the rotating shaft and can rotate around the rotating shaft; the lower end of the pushing shaft is connected to the mounting beam, and the upper end of the pushing shaft is arranged in the chute provided below the label receiving structure fixing plate; the label receiving structure is installed on the label receiving structure fixing plate;

[0011] When the cylinder works, the telescopic rod of the cylinder drives the mounting beam to move upward, and then pushes the label receiving structure fixing plate to rotate upward around the rotating shaft through the pushing shaft; until the two symmetrically arranged label receiving structure fixing plates are closed; after the labeling is completed, the telescopic rod of the cylinder retracts, driving the mounting beam to move downward, and then making the label receiving structure fixing plate rotate downward around the rotating shaft through the pushing shaft until it returns to the original position.

[0012] Further, it also includes an adjusting column, a hexagonal nut, a retaining piece, and a sensor; an adjusting column is provided below the mounting beam. When the telescopic rod of the cylinder retracts and drives the mounting beam to move downward, the adjusting column is used to achieve limit and ensure that the label receiving structure installed on the label receiving structure fixing plate is in a horizontal state; the position of the adjusting column is locked by a hexagonal nut;

[0013] A sensor is also installed on the rotating bottom plate, and a retaining piece is installed on the mounting beam. The sensor cooperates with the retaining piece. When the mounting beam moves downward in place, the retaining piece triggers the sensor, and the sensor outputs a signal indicating that the cylinder has retracted in place.

[0014] Further, it also includes an elastic block, which is embedded in the vertically-oriented groove at the top of the fixed plate. A rotating shaft is fixed at the top of the groove, and the height of the elastic block is slightly lower than the center connection line of the two rotating shafts. During the labeling process, the wire is placed on the elastic block in the groove. For wires with different diameters, the relative distance between the wire and the label receiving structure does not need to be adjusted to achieve the fitting with the label. The elastic block is made of silicone with a hardness of 40° - 70°.

[0015] Further, the rotating structure includes an adapter plate, a swing table, and a rotating plate. The swing table is fixed to the adapter plate by screws, the rotating plate is fixed to the swing table by screws, and the adapter plate is fixed to the moving structure. Two symmetrical fixing positions are provided on the rotating plate, and a set of label receiving structures are respectively installed through the rotating bottom plates.

[0016] After the label receiving structure completes the first label receiving, the swing table rotates 180°, swapping the positions of the label receiving structure that has completed label suction and the label receiving structure that has not completed label suction, and preparing for the second label suction.

[0017] Further, the moving structure includes a motor, a motor mounting plate, a coupling, and a single-axis component. The motor is connected to the coupling through the motor mounting plate, thereby driving the single-axis component to move axially. The rotating structure is fixed to the single-axis component through the adapter plate. After the swing table completes rotation, the single-axis component moves an appropriate distance to cooperate with the label receiving structure to complete the second label receiving.

[0018] Further, the two sets of label receiving structures are fixed to the rotating plate by screws and are horizontally arranged along the movement direction of the single-axis component. Each set of label receiving structures is connected to a set of label receiving structures. After connection, the two sets of label receiving structures are in a mirror image position on the label receiving structure.

[0019] Further, when the air cylinder is in a contracted state, the label receiving structure is in a horizontal state. After the label receiving structure completes two label receptions, the air cylinder extends to complete the fitting of the label.

[0020] Further, the present invention also proposes a labeling method, which includes the following steps:

[0021] Step 1: At a specified position, the label receiving structure completes the first label receiving action.

[0022] Step 2: After the first label receiving, the rotating structure rotates 180°, and the moving structure makes an appropriate displacement so that the label receiving structure at the mirror image position moves to the specified position for the second label receiving action.

[0023] Step 3: After the two label receiving actions are completed, the moving structure moves the label receiving structure under the wire. After the wire presses on the elastic block, the label receiving structure simultaneously labels the wire with two labels.

[0024] Step 4: After the labeling is completed, the labeling structure resets. Driven by the moving structure, it returns to the designated position to prepare for the next cyclic action. During the process of returning to the original position, the rotating structure rotates and resets simultaneously.

[0025] The beneficial effects of the present invention are as follows:

[0026] (1) The present invention enables two groups of label receiving structures to complete two label receptions at a designated position through rotation and appropriate displacement.

[0027] (2) The present invention can simultaneously complete the labeling work of two labels on the wire.

[0028] (3) The present invention can complete the labeling work on wires with different wire diameters without adjusting the relative distance between the wire and the label receiving structure.

[0029] (4) The rotating labeling mechanism of the present invention can complete two label receptions at a designated position through a 180° rotation and appropriate displacement during the automatic offline process, and complete the labeling work of two labels on the wire at one time, shortening the offline duration and improving the equipment efficiency.

[0035] The present invention provides a rotating labeling mechanism for an automatic offline labeling machine, which can complete a second label reception through a 180° rotation and appropriate displacement after completing a first label reception at a designated position. After the two label receptions are completed, the whole moves under the wire and can complete the labeling work of two labels on wires with different wire diameters at one time. After the labeling is completed, during the process of returning to the original position, it rotates reversely and resets to return to the starting label reception position to prepare for the next label reception work.

[0036] As Figure 1 shown, this mechanism mainly includes a label receiving structure 1, a labeling structure 2, a rotating structure 3 and a moving structure 4, which jointly realize the fitting of two labels on the wire at one time.

[0037] On the two support arms of the rotating structure 3, the labeling structures 2 are symmetrically installed. On both of the two labeling structures 2, the label receiving structures 1 are installed, and the two label receiving structures 1 are in mirror positions. The rotating structure 3 is installed on the moving structure 4; after the first label receiving is completed at the specified position, through the rotation of the rotating structure 3 by 180° and appropriate displacement, the label receiving structure that has completed label suction and the label receiving structure that has not completed label suction are interchanged in position, and the second label suction is carried out; after the two label receiving operations are completed, the whole is moved to below the wire through the moving structure 4, and the labeling of two labels is completed at one time for wires with different wire diameters. After the labeling is completed, during the process of returning to the original position, the rotating structure 3 rotates reversely to reset and returns to the starting label receiving position to prepare for the next label receiving operation.

[0038] As Figure 2 shown, the label receiving structure 1 includes a lower suction plate 11, an upper left suction plate 12, and an upper right suction plate 13. The lower suction plate 11 is sealed with the upper left suction plate 12 and the lower right suction plate 13 respectively by means of a laser welding machine, and a cavity is formed inside. The upper left suction plate 12 and the lower right suction plate 13 are designed with bosses, and small holes of the same size are opened on the bosses for adsorbing labels.

[0039] The above-mentioned boss design of the present invention can further reduce the label suction area, making it more precise, and can accurately adsorb small-sized labels, such as labels of 0.3mm * 0.3mm. Existing general labeling mechanisms cannot perform high-precision, high-accuracy, and high-success-rate labeling on such small-sized labels.

[0040] As Figure 3 shown, the labeling structure 2 includes a rotating bottom plate 202, a slide rail bottom plate 211, a guide rail 210, a mounting beam 207, a cylinder 201, an adjusting gasket 204, a fixing plate 206, a label receiving structure fixing plate 212, a push shaft 213, and a rotating shaft 214;

[0041] The air cylinder 201 is arranged below the rotating base plate 202. The telescopic rod of the air cylinder 201 passes through the through hole provided on the rotating base plate 202 and is fixedly connected to the mounting beam 207 located above the rotating base plate 202. An adjusting gasket 204 is sleeved on the telescopic rod above the rotating base plate 202; the slide rail base plate 211 is fixed on the rotating base plate 202, and the guide rail 210 is fixed on the slide rail base plate 211 by screws and is in a vertical state. The mounting beam 207 is fixed on the two slide rails 210 and can move up and down along the vertical direction on the slide rails 210. The mounting beam 207 is ensured to be horizontal during installation; the fixing plate 206 is fixedly connected to one end of the rotating base plate 202. The rotating shaft 214 is installed at the top of the fixing plate 206. The label receiving structure fixing plate 212 is connected to the rotating shaft 214 and can rotate around the rotating shaft 214; the lower end of the push shaft 213 is connected to the mounting beam 207, and the upper end of the push shaft 213 is arranged in the chute provided below the label receiving structure fixing plate 212; the label receiving structure 1 is installed on the label receiving structure fixing plate 212;

[0042] When the air cylinder 201 works, the telescopic rod of the air cylinder 201 drives the mounting beam 207 to move upward, and then pushes the label receiving structure fixing plate 212 to rotate upward around the rotating shaft 214 through the push shaft 213; until the two symmetrically arranged label receiving structure fixing plates 212 are closed; after the labeling is completed, the telescopic rod of the air cylinder 201 retracts, drives the mounting beam 207 to move downward, and then makes the label receiving structure fixing plate 212 rotate downward around the rotating shaft 214 through the push shaft 213 until it returns to the original position.

[0043] Further, the labeling structure 2 further includes an adjusting column 208, a hexagon nut 209, a retaining piece 205 and a sensor 203; an adjusting column 208 is provided below the mounting beam 207. When the telescopic rod of the air cylinder 201 retracts and drives the mounting beam 207 to move downward, the adjusting column 208 is used to achieve limit and ensure that the label receiving structure 1 installed on the label receiving structure fixing plate 212 is in a horizontal state; the position of the adjusting column 208 is locked by the hexagon nut 209;

[0044] A sensor 203 is also installed on the rotating base plate 202, and a retaining piece 205 is installed on the mounting beam 207. The sensor 203 cooperates with the retaining piece 205. When the mounting beam 207 moves downward in place, the retaining piece 205 triggers the sensor 203, and the sensor 203 outputs a signal indicating that the air cylinder has retracted in place.

[0045] Further, the labeling structure 2 further includes an elastic block 215, which is embedded in a vertically-oriented groove at the top of the fixed plate 206. A rotating shaft 214 is fixed at the top of the groove. The height of the elastic block 215 is slightly lower than the center line connecting the two rotating shafts 214. During the labeling process, the wire is placed on the elastic block 215 in the groove. For wires with different diameters, the relative distance between the wire and the label receiving structure 1 does not need to be adjusted, and the fitting with the label can be achieved. The elastic block 215 is made of silicone with a hardness of 40°-70°.

[0046] Two groups of labeling structures 2 are fixed on the rotating plate 33 by screws and are horizontally arranged along the moving direction of the single-axis assembly 44. Each group of labeling structures 2 is connected to a group of label receiving structures 1. After connection, the two groups of label receiving structures 1 are in mirror positions on the labeling structure 2.

[0047] When the air cylinder 201 is in a contracted state, the label receiving structure 1 is in a horizontal state. When the label receiving structure 1 has completed two label receptions, the air cylinder 201 extends to complete the fitting of the label.

[0048] As Figure 4 shown, the rotating structure 3 includes an adapter plate 31, a swing table 32, and a rotating plate 33. The swing table 32 is fixed on the adapter plate 31 by screws, and the rotating plate 33 is fixed on the swing table 32 by screws. The adapter plate 31 is fixed on the moving structure 4. Two symmetric fixed positions are provided on the rotating plate 33, and a set of labeling structures 2 are respectively installed through the rotating bottom plate 202.

[0049] After the label receiving structure 1 has completed the first label reception, the swing table 32 rotates 180°, swapping the positions of the label receiving structure 1 that has completed label suction and the label receiving structure 1 that has not completed label suction, and preparing for the second label suction.

[0050] As Figure 5 shown, the moving structure 4 includes a motor 41, a motor mounting plate 42, a coupling 43, and a single-axis assembly 44. The motor 41 is connected to the coupling 43 through the motor mounting plate 42, thereby driving the single-axis assembly 44 to move axially. The rotating structure 3 is fixed on the single-axis assembly 44 through the adapter plate 31. After the swing table 32 has completed rotation, the single-axis assembly 44 moves an appropriate distance to cooperate with the label receiving structure 1 to complete the second label reception. After two label receptions are completed, under the action of this structure, the whole moves below the wire to prepare for labeling.

[0051] The present invention also proposes a labeling method, including the following steps:

[0052] Step 1: At a specified position, the label receiving structure completes the first label reception action.

[0053] Step 2: After the first label reception, the rotating structure rotates 180°, and the moving structure makes an appropriate displacement, so that the label receiving structure at the mirror position moves to the specified position to perform the second label reception action.

[0054] Step 3: After the two label receiving actions are completed, the moving structure moves the labeling structure under the wire. After the wire presses on the elastic block, the labeling structure simultaneously applies two labels to the wire.

[0055] Step 4: After labeling is completed, the labeling structure resets. Driven by the moving structure, it returns to the designated position to prepare for the next cyclic action. During the process of returning to the original position, the rotating structure simultaneously rotates and resets.

[0056] The rotary labeling mechanism of the present invention can complete two label receptions at a specified position through a 180° rotation and an appropriate displacement during the automatic offline process, and apply two labels to the wire at one time.

Step 4: After the labeling is completed, the labeling structure is reset. Driven by the moving structure, it returns to the designated position to prepare for the next cyclic action. During the process of returning to the original position, the rotating structure rotates and resets simultaneously.
