[0002] In the manufacturing process, inkjet coding devices are widely used. For example, printing the production date, barcode, QR code, and serial code on the product packaging can be called inkjet coding. Especially before the workpiece is produced, packaged and shipped out of the factory, inkjet coding devices are used to print the factory logo and production date on the surface of the workpiece.

[0003] A patent with the publication number CN112622441B discloses a workpiece automatic coding device and method, which facilitates the transportation of workpieces through a conveyor line unit, and the lifting unit supports and fixes the workpieces during the coding process. Two relatively sliding slides are provided, and an annular guide rail and a gear ring are provided on the slide to facilitate large workpieces to enter and exit the coding unit. The inkjet terminal moves on the annular guide rail through the gear ring, which facilitates the rotation of the inkjet terminal for coding, greatly saving energy and power, making its operation and control more convenient and accurate; by using the first half gear ring and the second half gear ring to enclose the gear ring, the second fan-shaped guide rail and the first fan-shaped guide rail to enclose the annular guide rail, which greatly expands its application range, thereby meeting the coding requirements of workpieces of different specifications, and can be automatically taken out of the coding unit after coding is completed. And the degree of automation is high, which greatly reduces the labor intensity of operators and improves operating efficiency; the use of automated operation ensures the stability and consistency of coding quality.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example

[0023] like Figures 1 to 9 As shown, a coding device based on a circular workpiece according to an embodiment of the present invention comprises a fixed frame 1, a support frame 9 is installed at the bottom of the inner cavity of the fixed frame 1, a rotating roller 13 is rotatably connected to the upper end of the support frame 9, and a rubber anti-skid tooth block is arranged outside the rotating roller 13 for driving the circular workpiece 4 to rotate, and a feeding assembly 7 is rotatably connected to both ends of the rotating roller 13; The feeding assembly 7 includes a type rotating frame 71 installed at both ends of the rotating roller 13, and multiple brackets 72 are fixedly connected to the outside of both ends of the type rotating frame 71, and a slide groove 73 is opened in one end of the multiple brackets 72, and a first spring 74 is fixedly connected to the bottom of the inner cavity of the slide groove 73, and a slide rod 75 is fixedly connected to one end of the first spring 74, and a clamping block 76 is fixedly connected to one end of the slide rod 75, and one end face of the clamping block 76 is arranged in an arc shape, and an anti-skid rubber pad is arranged on the outside of the clamping block 76, which is used to clamp the circular workpiece 4 for conveying and transportation; A lifting rod 2 is installed on one end surface of the fixing frame 1, and an electric push rod 20 is installed on one side of the lifting rod 2 for driving the electric push rod 20 to move up and down. The output shaft end of the electric push rod 20 is fixedly connected to a laser inkjet printer 3.

[0024] Specifically, in the prior art, an operator usually places a circular workpiece under a laser inkjet printer, and uses a fixture to clamp and position the circular workpiece, and then drives the circular workpiece to rotate slowly through a servo motor, and at the same time starts the laser inkjet printer to inkjet the surface of the circular workpiece during the rotation. After the inkjet printing is completed, the operator removes and recycles the circular workpiece in the fixture, and replaces a new circular workpiece for inkjet printing. However, this inkjet printing processing method is not only cumbersome to operate, but also because it is impossible to automatically load and unload the circular workpiece and drive the circular workpiece to rotate for inkjet printing, resulting in low production efficiency of inkjet printing on the surface of the circular workpiece. The present invention installs the fixing frame 1 at the tail end of the conveyor belt for conveying the circular workpiece 4, and then conveys the circular workpiece 4 into the fixing frame 1 through the conveyor belt, and drives the workpiece rotating frame 71 to rotate at the same time, and then the workpiece rotating frame 71 drives the bracket 72 to rotate, and the bracket 72 drives the slide bar 75 to rotate, and then drives the clamping block 76 to rotate synchronously, and one end face of the clamping block 76 is arranged in an arc shape, and the outside of the clamping block 76 is provided with an anti-skid rubber pad, and in the process of driving the clamping block 76 to rotate, the clamping block 76 will clamp and lift the circular workpiece 4 at the tail end of the conveyor belt, and after the clamping block 76 drives the circular workpiece 4 to rotate 160 degrees in a circle, the circular workpiece 4 will be conveyed to the rotating frame. The outside of the roller 13, and then the clamping block 76 continues to rotate, so that the rotating roller 13 is in contact with the circular workpiece 4, and the clamping block 76 is disengaged from the circular workpiece 4, and at the same time, the lifting rod 2 is started to drive the electric push rod 20 to move to adjust the laser inkjet printer 3 for focusing, and then the electric push rod 20 is started to drive the laser inkjet printer 3 to adjust the inkjet position, and at the same time, the rotating roller 13 is driven to rotate, and the outside of the rotating roller 13 is provided with a rubber anti-slip tooth block, and then the rotating roller 13 uses the rubber anti-slip tooth block to drive the circular workpiece 4 to rotate, and at the same time, the laser inkjet printer 3 is started to inkjet the circular workpiece 4, so that the laser inkjet printer 3 inkjet the circular workpiece 4 on the surface of the circular workpiece 4 in a ring shape, thereby solving the above-mentioned problem.

[0025] like Figure 3 , Figure 4 and Figure 8 As shown, the rotating roller 13 is fixedly connected to the outside with a first sprocket 14, the first sprocket 14 is externally transmission-connected to a chain 16, one end of the chain 16 is internally transmission-connected to a second sprocket 15, and the second sprocket 15 is rotationally connected to the inner cavity of the support frame 9, a driving motor 17 is installed on one side of the support frame 9, and the output shaft end of the driving motor 17 passes through the support frame 9 and is fixedly connected to the second sprocket 15.

[0026] Specifically, when the circular workpiece 4 is sprayed with code in a ring shape on the surface, the driving motor 17 is started to drive the second sprocket 15 to rotate, and then the second sprocket 15 drives the chain 16 to rotate, and at the same time, the chain 16 drives the first sprocket 14 to rotate. During the rotation of the first sprocket 14, the rotating roller 13 is driven to rotate. Since the rotating roller 13 is provided with a rubber anti-skid tooth block on the outside, the rotating roller 13 drives the circular workpiece 4 to rotate by using the rubber anti-skid tooth block, and at the same time, the laser spray coder 3 is started to spray code on the circular workpiece 4. As a result, during the rotation of the circular workpiece 4, the laser spray coder 3 can spray code on the surface of the circular workpiece 4 in a ring shape, thereby improving the working efficiency of spraying code on the surface of the circular workpiece 4.

[0027] like Figures 2 to 4 and Figure 7 As shown, the workpiece rotating frame 71 is rotatably connected to the inner wall of the fixed frame 1, and a servo motor 10 is installed on one end face of the fixed frame 1. The output shaft end of the servo motor 10 passes through the fixed frame 1 and is fixedly installed on the workpiece rotating frame 71, and is used to drive the workpiece rotating frame 71 to rotate, clamp and convey the circular workpiece 4.

[0028] Specifically, when the circular workpiece 4 is being conveyed and inkjet processed, the servo motor 10 is started to drive the workpiece rotating frame 71 to rotate, and at the same time drive the bracket 72 to rotate, and the bracket 72 drives the slide bar 75 to rotate, and then drives the clamping block 76 to rotate synchronously, and one end face of the clamping block 76 is arranged in an arc shape, and an anti-slip rubber pad is arranged on the outside of the clamping block 76, and then in the process of driving the clamping block 76 to rotate, the clamping block 76 will clamp the circular workpiece 4 at the tail end of the conveyor belt and lift it to the rotating roller 13 for conveying it, thereby realizing the automatic conveying of the circular workpiece 4 for inkjet processing, and improving the production efficiency of the circular workpiece 4 for inkjet processing.

[0029] like Figure 3 , Figure 5 and Figure 6 As shown, an intermittent unloading component 6 is installed on one side of the fixed frame 1, and the intermittent unloading component 6 includes two first mounting plates 61 installed on one side of the fixed frame 1, and the two first mounting plates 61 are fixedly connected with a fixing rod 62 on their surfaces close to each other, a fixing cylinder 63 is fixedly connected to one end of the fixing rod 62, and a cross rotating rod 65 is rotatably connected to the inner cavity of the fixing cylinder 63, a unloading plate 66 is fixedly connected to one end of the cross rotating rod 65, and the unloading plate 66 is used to receive the circular workpiece 4 for storage.

[0030] like Figure 3 , Figure 5 and Figure 6As shown, a torsion spring 64 is fixedly connected to one end of the cross rotating rod 65, and one end of the torsion spring 64 is fixedly connected to the bottom of the inner cavity of the fixed cylinder 63. An L-shaped mounting plate 67 is installed at one end of the blanking plate 66 for receiving the limited circular workpiece 4. Both ends of the L-shaped mounting plate 67 are fixedly connected to toggle blocks 69. The two first mounting plates 61 are fixedly connected to the surfaces close to each other with L-shaped limiting rods 68 for limiting the flipping of the blanking plate 66.

[0031] The cam 76 is pressed against the workpiece 4 and the locking cam 78 is pressed against the workpiece 4, and the locking cam 78 is pressed against the workpiece 4 by the locking cam 78. 65 drives the unloading plate 66 to rotate and reset, thereby making the unloading plate 66 abut against the L-shaped limit rod 68, thereby realizing the quantitative unloading and loading of the circular workpiece 4, and then after the driving slide bar 75 drives the clamping block 76 to rotate ninety degrees, the clamping block 76 will drive the circular workpiece 4 to be transported into between the driven roller 86 and the rotating roller 13 for loading and waiting for coding processing, thereby solving the problem that when the existing coding device based on circular workpieces is coding on the surface of the circular workpiece, the circular workpiece is usually placed under the laser coding device, and then the operator slowly rotates the circular workpiece or uses the motor to drive the clamp alone to drive the circular workpiece to rotate, and at the same time start the laser coding device to run, and code the surface of the circular workpiece during its rotation. However, this coding method is not only cumbersome to operate, but also cannot form an automated form of coding work, resulting in low coding efficiency on the surface of the circular workpiece.

[0032] like Figure 3 , Figure 4 and Figure 6 As shown, two L-shaped fixing blocks 5 are installed on one side of the upper end of the fixing frame 1, and a limiting column 19 is fixedly connected between the two L-shaped fixing blocks 5 for abutting against the circular workpiece 4 and pushing the circular workpiece 4 to slide into the feeding assembly 7.

[0033] Specifically, when the clamp block 76 continues to push the toggle block 69 to drive the blanking plate 66 to move upward, the blanking plate 66 will drive the circular workpiece 4 to abut against the limit column 19, and then the clamp block 76 will disengage from the abutment with the toggle block 69, and then use the arc-shaped surface to slide to the outside of the circular workpiece 4 to clamp it, and the slide rod 75 continues to drive the clamp block 76 to rotate, the clamp block 76 will drive the circular workpiece 4 to rotate synchronously, and the upper surface of the circular workpiece 4 will abut against the limit column 19, and then the limit column 19 is used to push the circular workpiece 4 to slide into the inner cavity of the bracket 72, thereby ensuring that the clamp block 76 clamps the circular workpiece 4 more tightly, and at the same time, the bracket 72 is used to lift the bottom of the circular workpiece 4 to ensure the stability of the circular workpiece 4 in the inner cavity of the bracket 72, further improving the efficiency of automatic conveying and loading of the circular workpiece 4, and at the same time improving the coding production efficiency of the circular workpiece 4. Example

[0034] like Figure 1 , Figure 3 and Figure 8 As shown, a material guide block 11 is installed on one side of the inner cavity of the fixed frame 1, and an L-shaped material return rack 12 is installed on one side of the material guide block 11. The L-shaped material return rack 12 is used to push the circular workpiece 4 to return and collect the material. Control buttons 18 are provided on both walls of the inner cavity of the fixed frame 1 for starting the laser inkjet printer 3 and the drive motor 17 to run simultaneously.

[0035] like Figure 4 , Figure 8 and Fig. 9 As shown, the inner cavity of the fixed frame 1 is provided with a coding auxiliary mechanism 8, and the coding auxiliary mechanism 8 includes a driven roller 86 slidably arranged in the inner cavity of the fixed frame 1, and the driven roller 86 is used to limit the installation of the circular workpiece 4 and cooperate with the driving of the circular workpiece 4 to rotate for coding.

[0036] Specifically, after the bracket 72 cooperates with the clamping block 76 to transport the circular workpiece 4 into between the driven roller 86 and the rotating roller 13, the bracket 72 will drive the slide bar 75 to rotate continuously, and at the same time, the slide bar 75 drives the clamping block 76 to disengage the circular workpiece 4 and slide to the two ends of the driven roller 86. Since four brackets 72 are arranged outside the industrial rotating frame 71 and are arranged in a cross shape, after the clamping block 76 slides to the two ends of the driven roller 86, the clamping block 76 located at the bottom of the inner cavity of the fixed frame 1 will press the control button 18, The control button 18 starts the laser coder 3 and the drive motor 17 at the same time, and the drive motor 17 drives the rotating roller 13, which then drives the circular workpiece 4 to rotate between the driven roller 86 and the rotating roller 13, and then the laser coder 3 sprays the circular workpiece 4 surface in a ring shape during the rotation process, and the control button 18 can be replaced with an infrared sensing button as needed. After the clamp 76 is formed into an infrared sensing probe, the laser coder 3 and the drive motor 17 are automatically started to improve the accuracy of the coding of the circular workpiece 4.

[0037] like Figure 4 , Figure 8 and Fig. 9 As shown, the driven roller 86 is externally rotatably connected to the annular support frame 83, a receiving groove 84 is opened in the lower end of the annular support frame 83, a second mounting block 81 is installed at the bottom of the inner cavity of the fixed frame 1, and a T-shaped fixing rod 82 is fixed to the upper end of the second mounting block 81, and the T-shaped fixing rod 82 is externally slidably connected in the inner cavity of the receiving groove 84.

[0038] like Figure 4 , Figure 8 and Fig. 9 As shown, a second spring 85 is fixedly connected to the upper end of the T-shaped fixing rod 82 , and one end of the second spring 85 is fixedly connected to the upper wall of the inner cavity of the receiving groove 84 . Round blocks 87 are provided at both ends of the driven roller 86 , and the round blocks 87 abut against the clamping block 76 .

[0039] Specifically, after the coding of the circular workpiece 4 is completed, the bracket 72 is continuously driven to rotate, and the bracket 72 drives the sliding rod 75 to rotate, and at the same time drives the clamping block 76 to rotate, so that the clamping block 76 abuts against the round block 87, and then pushes the round block 87 to move downward, and then the round block 87 drives the driven roller 86 to move downward, and at the same time the driven roller 86 drives the annular support frame 83 to move downward, and makes the annular support frame 83 slide outside the T-shaped fixed rod 82, and after the driven roller 86 moves downward and abuts against the bottom of the inner cavity of the L-shaped stripping frame 12, the L-shaped stripping frame 12 will be inserted between the rotating roller 13 and the driven roller 86, and at the same time push the circular workpiece 4 after coding between the rotating roller 13 and the driven roller 86, so that the circular workpiece 4 can be more easily attached to the surface of the driven roller 86 and roll onto the guide block 11, and one side of the fixed frame 1 is installed with the conveyor belt, and then the guide block 11 is used to transport the coded circular workpiece 4 to the conveyor belt, and the conveyor belt is used to transport it to the subsequent printing The clamping block 76 is pressed against the upper surface of the workpiece 83, and the clamping block 76 is pressed against the lower surface of the workpiece 83, and the first spring 74 is pressed against the lower surface of the workpiece 83, so that the clamping block 76 is released from the contact with the workpiece 83, and the second spring 74 is pressed against the upper surface of the workpiece 83, so that the clamping block 76 is released from the contact with the workpiece 83, and the second spring 74 is pressed against the lower surface of the workpiece 83, so that the second spring 74 is pressed against the lower surface of the workpiece

[0040] The working principle is that the fixed frame 1 is installed at the tail end of the conveyor belt for conveying the circular workpiece 4, and then the circular workpiece 4 is conveyed into the fixed frame 1 through the conveyor belt, and the workpiece rotating frame 71 is driven to rotate, and then the workpiece rotating frame 71 drives the bracket 72 to rotate, and the bracket 72 drives the slide bar 75 to rotate, and then drives the clamping block 76 to rotate synchronously, and one end face of the clamping block 76 is arranged in an arc shape, and the outside of the clamping block 76 is provided with an anti-slip rubber pad, and in the process of driving the clamping block 76 to rotate, the clamping block 76 will The circular workpiece 4 at the tail end of the conveyor belt is clamped and lifted up, and after the clamp block 76 drives the circular workpiece 4 to rotate 160 degrees in a circular shape, the circular workpiece 4 will be conveyed to the outside of the rotating roller 13, and then the clamp block 76 continues to rotate, so that the rotating roller 13 abuts against the circular workpiece 4, and the clamp block 76 and the circular workpiece 4 are disengaged, and at the same time, the lifting rod 2 is started to drive the electric push rod 20 to move and adjust the laser inkjet printer 3 to focus, and then the electric push rod 20 is started to drive the laser inkjet printer 3 to adjust the inkjet position; When the circular workpiece 4 is loaded and stenciled, the sliding rod 75 is driven to drive the clamping block 76 to rotate. At the same time, the clamping block 76 pushes the toggle block 69 to move upward during the rotation process, and the toggle block 69 drives the L-shaped mounting plate 67 to move upward, so that the L-shaped mounting plate 67 drives the blanking plate 66 to flip, and then the circular workpiece 4 slides into the inner cavity of the L-shaped mounting plate 67 through the blanking plate 66, and then the clamping block 76 is continuously driven to rotate, and the blanking plate 66 drives the cross-rotating rod 65 to rotate in the inner cavity of the fixed cylinder 63, and at the same time, the cross-rotating rod 65 twists the torsion spring 64 to twist, and the blanking plate 66 cannot After the flipping, the clamp block 76 will be disengaged from the abutment with the toggle block 69, and at the same time slide to the outside of the circular workpiece 4 to clamp it. After the clamp block 76 is disengaged from the abutment with the toggle block 69, the torsion spring 64 twists the cross-rotating rod 65 to rotate, and the cross-rotating rod 65 drives the blanking plate 66 to rotate and reset, thereby making the blanking plate 66 abut against the L-shaped limit rod 68, thereby realizing the quantitative unloading and loading of the circular workpiece 4. Then, after the driving slide rod 75 drives the clamp block 76 to rotate ninety degrees, the clamp block 76 drives the circular workpiece 4 to be transported between the driven roller 86 and the rotating roller 13 for loading and waiting for coding processing; After the circular workpiece 4 is conveyed between the driven roller 86 and the rotating roller 13 by the bracket 72 and the clamping block 76, the bracket 72 will drive the slide bar 75 to rotate continuously, and at the same time, the slide bar 75 drives the clamping block 76 to disengage the circular workpiece 4 and slide to the two ends of the driven roller 86. Since there are four brackets 72 outside the industrial rotating frame 71 and they are arranged in a cross shape, after the clamping block 76 slides to the two ends of the driven roller 86, the clamping block 76 located at the bottom of the inner cavity of the fixed frame 1 will press the control button 18 and make The control button 18 starts the laser coder 3 and the drive motor 17 at the same time, and the drive motor 17 drives the rotating roller 13, which then drives the circular workpiece 4 to rotate between the driven roller 86 and the rotating roller 13, and then the laser coder 3 sprays the circular workpiece 4 in a ring shape during the rotation process. The control button 18 can be replaced with an infrared sensing button as needed. After the clamp block 76 forms an infrared sensing probe, the laser coder 3 and the drive motor 17 are automatically started to improve the accuracy of the coding of the circular workpiece 4. After the coding of the circular workpiece 4 is completed, the bracket 72 is continuously driven to rotate, and the bracket 72 drives the sliding rod 75 to rotate, and at the same time drives the clamping block 76 to rotate, so that the clamping block 76 abuts against the round block 87, and then pushes the round block 87 to move downward, and then the round block 87 drives the driven roller 86 to move downward, and at the same time the driven roller 86 drives the annular support frame 83 to move downward, and the annular support frame 83 slides outside the T-shaped fixed rod 82, and after the driven roller 86 moves downward and abuts against the bottom of the inner cavity of the L-shaped unloading rack 12, the L-shaped unloading rack 12 will be inserted between the rotating roller 13 and the driven roller 86, and at the same time push the circular workpiece 4 after coding is completed between the rotating roller 13 and the driven roller 86, so that the circular workpiece 4 can fit more easily on the surface of the driven roller 86 The surface rolls onto the guide block 11, and one side of the fixed frame 1 is installed with the conveyor belt, and then the guide block 11 is used to transport the coded circular workpiece 4 to the conveyor belt, and the conveyor belt is used to transport it to the subsequent packaging station. After the clamping block 76 pushes the driven roller 86 to the bottom of the inner cavity of the L-shaped unloading frame 12, the clamping block 76 continues to rotate, and the clamping block 76 will slide along the surface of the round block 87, and then the clamping block 76 pushes the slide bar 75 to squeeze the first spring 74 to slide into the inner cavity of the slide groove 73, so that the clamping block 76 and the round block 87 are disengaged, and then the second spring 85 rebounds to push the annular support frame 83 to move upward, and at the same time the annular support frame 83 drives the driven roller 86 to move upward and reset, and the first spring 74 rebounds to push the slide bar 75 to drive the clamping block 76 to reset.
