[0002] At present, in the automobile industry, rubber tubes play a connecting role in automobile assembly, and the rubber tube 200 has different assembly marks 300 at both ends, which are used to guide the assembly operation. Figure 7 The upper side of the rubber tube is also provided with code spraying, which contains important traceable information such as supplier code, drawing number and batch number, and each rubber tube must have marks and code spraying.

[0003] The prior art adopts pad printing to print marks on both ends of the rubber tube, and adopts a laser device to spray codes on the upper side of the rubber tube. Specifically, one operator first pad prints one end of the rubber tube, then transfers the rubber tube to the next operator for laser code spraying, and finally transfers the rubber tube to the next operator to pad print the other end of the rubber tube. The whole process requires at least three operators to work together, which consumes labor. SUMMARY

[0004] In order to solve the problems of labor consumption and low efficiency in the existing rubber tube processing method, the present application provides a rubber tube pad printing and code spraying device to save labor.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: A rubber tube pad printing and code spraying device comprises a rack, a rotating disc and a motor, a processing seat, a seat lifting mechanism, a first pad printing device, a second pad printing device and a laser device. The rotating disc is horizontally connected to the upper side of the rack, and the motor is installed on the rack and can drive the rotating disc to rotate. The processing seat is provided at least four, and is evenly arranged on the upper side of the rotating disc along the outer periphery. The upper side of the processing seat is provided with a profiling groove matched with the rubber tube to prevent the rubber tube from moving on the processing seat. One end of the processing seat is hinged to the rotating disc. The processing seat has a first state and a second state. When the processing seat is in the first state, the processing seat is placed on the upper side of the rotating disc under the action of gravity, and one end of the rubber tube on the processing seat is horizontal.

The seat lifting mechanism is installed on the rack, and can rotate the processing seat to switch the state of the processing seat. The first pad printing device, the second pad printing device and the laser device are arranged on the upper side of three processing seats respectively. The first pad printing device pad prints the rubber tube on the processing seat in the first state. The laser device sprays codes on the upper side of the rubber tube. The second pad printing device pad prints the rubber tube on the processing seat in the second state.

[0006] Through the above setting, first, the state of the first switchable processing seat can be switched, and the two ends of the rubber tube are convenient to move; second, the motor drives the rotating disc to rotate, and the rubber tube on the processing seat passes through the first transfer printing device, the second transfer printing device and the laser device in turn, and the first transfer printing device, the second transfer printing device and the laser device process the rubber tube, without manual transfer of the rubber tube, saving manual work.

[0010] Further, the lifting mechanism is an electric cylinder installed vertically on the rack, and the output shaft of the electric cylinder is upwardly aligned with the corresponding support plate.

[0011] Through the above setting, the processing seat is driven to rotate by the extension and retraction of the electric cylinder.

[0012] Further, the number of processing seats is four, and the four outlet openings are uniformly arranged along the outer periphery of the rotating disc; the outlet opening is close to the hinged end of the processing seat; the lower side of the support plate is provided with an inclined surface; the lifting mechanism comprises a vertical column and a roller; the vertical column is installed on the upper side of the rack; the roller is rotatably connected to the upper end of the vertical column; when the rotating disc rotates, the roller is in contact with the inclined surface and rolls along the inclined surface; under the action of the inclined surface, the roller drives the processing seat to rotate upward to the second state; after the second transfer printing device completes the transfer printing, the rotating disc continues to rotate, the roller continues to be driven by the inclined surface, and after the roller is separated from the inclined surface, the processing seat rotates to the above of the outlet opening under the action of inertia, so as to pour the rubber tube into the outlet opening.

[0013] Through the above setting, the lifting mechanism does not need to be provided with a power mechanism, saving cost and simplifying the structure; in addition, the lifting mechanism can pour the processed rubber tube out of the outlet by rotating the processing seat, further improving the processing efficiency.

[0023] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] See Figures 1-2A rubber tube pad printing and coding device includes: a frame 3, a turntable 4 and a motor (not shown in the figure), a processing seat 5, a lifting mechanism 6, a first pad printing device 7, a second pad printing device 8, and a laser device 9; the turntable 4 is horizontally rotatably connected to the upper side of the frame 3, and the motor is mounted on the frame 3 and can drive the turntable 4 to rotate; at least four processing seats 5 are provided, and they are evenly arranged on the upper side of the turntable 4 along the outer periphery. The upper side of the processing seat 5 is provided with a contour groove 51 adapted to the rubber tube to prevent the rubber tube from moving on the processing seat 5. One end of the processing seat 5 is hinged to the turntable 4. The processing seat 5 is provided in a first state and a second state. The processing seat 5 is in the first state. When the processing seat 5 rests on the upper side of the turntable 4 under the action of gravity, one end of the rubber tube on the processing seat 5 is horizontal. When the processing seat 5 is in the second state, the processing seat 5 is tilted so that the other end of the rubber tube on the processing seat 5 is horizontal. The lifting mechanism 6 is installed on the frame 3. The lifting mechanism 6 can rotate the processing seat 5 to switch the state of the processing seat 5. The first pad printing device 7, the second pad printing device 8 and the laser device 9 are respectively set on the upper side of three of the processing seats 5. The first pad printing device 7 transfers the rubber tube on the processing seat 5 in the first state, the laser device 9 prints on the upper side of the rubber tube, and the second pad printing device 8 transfers the rubber tube on the processing seat 5 in the second state.

[0025] With the above settings, firstly, the state of the processing seat 5 can be switched to facilitate the printing of both ends of the pad printing tube 200; secondly, the motor drives the turntable 4 to rotate, so that the tube on the processing seat 5 passes through the first pad printing device 7, the second pad printing device 8 and the laser device 9 in sequence. The first pad printing device 7, the second pad printing device 8 and the laser device 9 process the tube without the need for manual transfer of the tube, thus saving labor.

[0026] In this application, the turntable 4 can be circular, and the motor is connected to the center of the turntable 4. The motor can be a servo motor, which has the characteristics of high rotational accuracy, improving processing accuracy, and has an angle feedback function to facilitate control of the rotation angle of the turntable 4 each time. The number of processing seats 5 is specifically set to six. One end of the processing seat 5 can be hinged to the turntable 4. The first pad printing device 7, the second pad printing device 8, and the laser device 9 can refer to existing pad printing devices and laser equipment, without being elaborated. In operation, the rubber tube is manually placed on the contour groove 51 of the processing seat 5. The contour groove 51 fits the surface of the rubber tube to prevent the rubber tube from wobbling on the upper side of the processing seat 5. The processing seat 5 rests on the turntable 4 under the action of gravity. The processing seat 5 is in the first state, with one end of the rubber tube horizontal. The motor drives the turntable 4. The first processing seat 5 moves to the first pad printing device 7, and then the motor stops. The first pad printing device 7 transfers the mark to the horizontal end of the tube. After the transfer printing is completed, the motor continues to drive the turntable 4. The first processing seat 5 moves to the laser device 9, and then the motor stops. The laser device 9 sprays the code onto the upper side of the tube. The motor continues to drive the turntable 4. The tube with the completed coding moves to the second pad printing device 8, and then the motor stops. The lifting mechanism 6 rotates the processing seat 5 upward, and the processing seat 5 tilts so that the other end of the tube is horizontal. The processing seat 5 switches to the second state, and the second pad printing device 8 transfers the mark to the horizontal end of the tube. The motor drives the turntable 4 to continue rotating. After the tube with the completed pad printing and coding is taken out, a new tube is manually placed on the processing seat 5 for a new round of processing.

[0027] As one implementation method, the pad printing and coding device also includes: a robotic arm 10 and a discharge hopper 11; the robotic arm 10 is mounted on the frame 3 and can hold the rubber tube on the processing seat 5; the discharge hopper 11 is installed at an angle on the side of the frame 3, and the robotic arm 10 places the rubber tube on the discharge hopper 11, and the rubber tube slides down the discharge hopper 11 to discharge the material.

[0028] With the above settings, robotic arm 10 can assist in unloading materials, further saving labor costs.

[0029] In this application, the robotic arm 10 can refer to the existing six-axis robotic arm 10. After two pad printing and one inkjet printing, the rubber tube moves to the robotic arm 10. The robotic arm 10 runs, takes out the rubber tube and places it on the discharge hopper 11. The rubber tube slides down the discharge hopper 11 to discharge the material.

[0030] As one implementation, a support plate 12 is provided on the lower side of the processing base 5, and multiple clearance holes 42 are provided on the turntable 4. The support plate 12 passes through the clearance holes 42, and the lifting mechanism 6 is provided on the lower side of the turntable 4. The lifting mechanism 6 drives the processing base 5 to rotate upward through the support plate 12 so that the processing base 5 switches to the second state.

[0031] As one implementation method, the lifting mechanism 6 is an electric cylinder that is vertically mounted on the frame 3, with the output axis of the electric cylinder aligned upwards with the corresponding support plate 12.

[0032] With the above setup, the machining base 5 is rotated by extending and retracting the electric cylinder.

[0033] In this application, the electric cylinder extends, and the output axis of the electric cylinder pushes the support plate 12 and the processing seat 5 upward to rotate upward. The extension amount of the electric cylinder can be controlled by the limit switch. When the processing seat 5 rotates to the second state, the electric cylinder stops, so that the other end of the rubber tube on the processing seat 5 is horizontal, which facilitates the transfer printing of the second pad printing device 8.

[0034] In another embodiment, see Figure 3 There are four processing seats 5, and four discharge ports 41 are evenly arranged along the outer periphery of the turntable 4. The discharge ports 41 are close to the hinge end of the processing seat 5. An inclined surface 121 is provided on the lower side of the support plate 12. See Figures 4-6 The lifting mechanism 6 includes a column 61 and a roller 62. The column 61 is installed on the upper side of the frame 3. The roller 62 is rotatably connected to the upper end of the column 61. The turntable 4 rotates, and the roller 62 contacts the inclined plane 121 and rolls along the inclined plane 121. Under the action of the inclined plane 121, the roller 62 pushes the processing seat 5 to rotate upward to the second state. After the second pad printing device 8 completes the pad printing, the turntable 4 continues to rotate, and the roller 62 continues to push the processing seat 5 to rotate upward under the action of the inclined plane 121. After the roller 62 is disengaged from the inclined plane 121, the processing seat 5 rotates to above the discharge port 41 under the action of inertia, so as to pour the rubber tube into the discharge port 41.

[0035] With the above settings, there is no need to set up a power mechanism for the lifting mechanism 6, which saves costs and simplifies the structure; in addition, the lifting mechanism 6 can tilt the processed hose out by rotating the processing seat 5, which further improves the processing efficiency.

[0036] In this application, the roller 62 reduces the friction between the lifting mechanism 6 and the inclined plane 121. When the processing seat 5 is in the first state, the roller 62 is lower than the upper end of the inclined plane 121 and higher than the lower end of the inclined plane 121. The turntable 4 rotates, causing the inclined plane 121 to move closer to the roller 62. After the roller 62 contacts the inclined plane 121, the roller 62 rolls along the inclined plane 121 and pushes the support plate 12 and the processing seat 5 to rotate upwards. See [reference needed] Figure 5 When the processing seat 5 moves to the second pad printing device 8, the processing seat 5 is just in the second state, see [reference]. Figure 5At this point, roller 62 is still located between the upper and lower ends of inclined plane 121; after the second pad printing device 8 completes the pad printing, turntable 4 continues to rotate, and roller 62 continues to drive processing seat 5 to rotate upward through support plate 12. When roller 62 disengages from inclined plane 121, processing seat 5 continues to rotate upward under inertia until processing seat 5 rotates above discharge port 41 and tilts the rubber tube on processing seat 5 into discharge port 41 for material discharge. See [link to documentation]. Figure 6 Then, the processing seat 5 is manually reset and the new hose is placed in the contour groove 51 for the next round of processing.

[0037] As one implementation method, the pad printing inkjet printer also includes a discharge plate 14, which is inclinedly arranged in the discharge port 41. The rubber tube tilted by the processing seat 5 falls onto the discharge plate 14, and the rubber tube slides down along the discharge plate 14 to discharge the material. The upper end of the discharge plate 14 is hinged to the turntable 4, and a top plate 13 is fixedly connected to the turntable 4. The top plate 13 supports the lower side of the discharge plate 14.

[0038] With the above configuration, the discharge plate 14 can receive the rubber tube tilted from the processing seat 5 and guide the rubber tube to discharge; the discharge plate 14 is hinged to the turntable 4 and can rotate upward to prevent the lifting mechanism 6 from damaging the discharge plate 14.

[0039] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
