Description

Technical Field

[0001] This utility model relates to the technical field of automated equipment, and in particular to an automatic inkjet printing device. Background Technology

[0002] In today's industrial production sector, there is a widespread and stringent demand for inkjet printing on product surfaces. This is particularly true in the battery manufacturing industry, where critical information such as trademarks, specifications, and manufacturer details must be printed on battery surfaces. However, traditional inkjet printing equipment or devices suffer from numerous drawbacks, often resulting in serious errors such as slanted, blurry, and inconsistent information. This not only affects the product's aesthetics and recognizability but can also lead to consumer misunderstandings, ultimately impacting the product's market competitiveness.

[0003] In battery production, inkjet printing on the workpiece surface is a crucial step. However, traditional inkjet printing equipment or devices suffer from the following problems in practical applications: low automation, especially when handling irregularly shaped batteries. Because the equipment cannot accurately identify and position the workpiece's location, orientation, and orientation, the printed information is prone to tilting, blurring, or inconsistency, failing to meet the requirements of high-precision inkjet printing. Furthermore, traditional equipment lacks efficient and accurate automation solutions for workpiece transfer and placement, particularly when handling workpieces of different shapes and sizes, where the equipment's adaptability and flexibility are insufficient.

[0004] With the rapid development of the battery manufacturing industry, the demand for automated and precision equipment is increasing. Traditional inkjet printing equipment cannot meet the requirements of modern production for high efficiency and high precision, especially in the fields of complex workpiece inkjet printing and irregularly shaped battery processing, where existing technology is inadequate. Therefore, developing an automated device that can achieve efficient and accurate workpiece transfer and precise inkjet printing is of significant practical importance.

[0005] In summary, existing inkjet printing equipment has many shortcomings in terms of workpiece positioning, transfer, and inkjet printing accuracy. There is an urgent need for a new type of automatic inkjet printing equipment solution to solve these problems and improve production efficiency and product quality. Utility Model Content

[0009] The feeding assembly, installed at one end of the frame, conveys the workpiece to be inkjet-printed into the equipment.

[0010] The discharge assembly, installed at the other end of the frame, conveys the inkjet-coded workpiece out of the equipment;

[0011] The rotating assembly, mounted on the frame, is equipped with a fixed fixture to fix and rotate the workpiece, allowing the workpiece to pass through the loading station, the coding station and the unloading station in sequence.

[0012] A transfer assembly, mounted on the frame, transfers workpieces from the feeding assembly to the rotating assembly, or transfers workpieces out of the rotating assembly; and

[0013] The inkjet printing assembly is installed on the frame at the position corresponding to the inkjet printing station, and is used to perform inkjet printing operations on the workpiece at the inkjet printing station.

[0014] The displacement end of the material transfer assembly is equipped with a visual inspection device and a gripping mechanism. The visual inspection device is used to perform visual inspection on the workpiece, thereby assisting the gripping mechanism in gripping and placing the workpiece.

[0015] Furthermore: the material transfer assembly is equipped with a first robotic arm, and a first camera and a first suction cup are respectively installed at the wrist joint at the farthest end of the first robotic arm. The first suction cup is used to transfer the workpiece from the feeding assembly to the rotating assembly, and the first camera performs visual inspection on the workpieces on the feeding assembly and the rotating assembly respectively.

[0016] Furthermore, the material transfer assembly is also equipped with a second robotic arm. At the wrist joint at the farthest end of the second robotic arm, there is a second camera and a second suction cup. The second suction cup is used to transfer the workpiece out of the rotating assembly, and the second camera performs visual inspection on the workpiece on the rotating assembly.

[0017] Furthermore: the second suction cup transfers the workpiece from the rotating assembly to the discharge assembly, and the second camera inspects the workpiece on the discharge assembly; or the second suction cup transfers the workpiece from the rotating assembly to the defective product assembly, and the second camera inspects the workpiece on the defective product assembly.

[0018] Furthermore, the coding assembly includes a coding bracket and a coding host. The coding bracket is installed on the frame at the position corresponding to the coding station, and the coding host is installed on the coding bracket, thereby performing coding operations on the workpiece.

[0019] Furthermore: the rotating assembly is equipped with an indexing plate, and multiple fixed fixtures are evenly spaced on the indexing plate to carry and transport the workpieces.

[0020] Furthermore: the rotating assembly is also equipped with a rotary joint, and the fixing fixture is equipped with a vacuum suction cup. One end of the rotary joint is connected to an external vacuum generating device, and the other end is connected to the vacuum suction cup.

[0021] Furthermore, the fixing fixture is also equipped with a sponge cushioning pad, which is installed on the adsorption end of the vacuum suction cup.

[0022] Furthermore, the fixture is also equipped with an air pump silencer, which is installed on the vacuum suction cup.

[0023] Furthermore, the rack is also equipped with an air filtration unit to provide clean air to the inside of the equipment.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. Highly Automated Operation: The automatic inkjet printing equipment of this patent application achieves automatic transfer of workpieces during feeding, rotation, and discharging by setting up an automated material transfer component. The first and second robotic arms of the material transfer component have clearly defined roles: the first robotic arm is responsible for transferring the workpiece from the feeding component to the rotating component, and the second robotic arm is responsible for transferring the workpiece from the rotating component to the discharging component or defective product component, which greatly improves production efficiency, reduces manual intervention, and lowers labor costs.

[0026] 2. Precise Visual Inspection Assistance: Simultaneously installing a visual inspection device and a gripping mechanism at the displacement end of the material transfer assembly offers significant advantages. Before the gripping mechanism grasps the workpiece, the visual inspection device performs visual inspection. Utilizing image capture and position detection technology, it calculates the workpiece's placement position, orientation, and posture parameters through visual algorithms and feeds this information back to the central control system, enabling the gripping mechanism to accurately grasp the workpiece. After the workpiece is placed, a second visual inspection is performed to ensure accurate placement, providing a precise positioning basis for subsequent inkjet printing. This effectively avoids inkjet printing errors caused by workpiece placement deviations, significantly improving inkjet printing quality.

[0027] 3. Stable Workpiece Fixing and Conveying: The rotating assembly uses an indexing plate in conjunction with multiple evenly spaced fixing fixtures to stably rotate and convey workpieces. Workpieces sequentially and orderly pass through the loading, coding, and unloading stations, completing the entire coding process. Vacuum suction cups on the fixing fixtures utilize vacuum negative pressure to strongly adhere to the workpieces, combined with a rotary joint to achieve negative pressure airflow for rotational conveying, ensuring the workpieces are firmly fixed throughout the indexing plate's rotation. Furthermore, sponge cushioning pads on the fixing fixtures provide cushioning for the workpieces, reducing adhesion marks on the workpiece surface and improving product quality; the air pump silencer reduces equipment operating noise, prevents backflow, protects the working environment, and enhances equipment operational stability.

[0028] With the above improvements, the equipment of this utility model can achieve rapid and accurate workpiece movement and positioning, integrate intelligent vision inspection solutions, and adapt to workpieces of different shapes and sizes, improving its applicability, flexibility and automation in the inkjet printing process, thereby improving production efficiency and product quality.

Detailed Implementation

[0039] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Please see Figures 1 to 6 In this embodiment of the present invention, an automatic inkjet printing device includes:

[0041] Frame 10 supports and mounts all the components of the entire equipment;

[0042] The feeding assembly 51 is installed at one end of the frame 10 and conveys the workpiece to be inkjet-printed into the equipment.

[0043] The discharge assembly 52 is installed at the other end of the frame 10 and conveys the ink-printed workpiece out of the equipment.

[0044] The rotating component 20 is installed on the frame 10 and is equipped with a fixed fixture 23 to fix and rotate the workpiece, so that the workpiece passes through the loading station 13, the inkjet station 14 and the unloading station 15 in sequence.

[0045] The transfer assembly 30, mounted on the frame 10, transfers workpieces from the feeding assembly 51 to the rotating assembly 20, or transfers workpieces out of the rotating assembly 20; and

[0046] The inkjet printing assembly 40 is installed on the frame 10 at the position corresponding to the inkjet printing station 14, and is used to perform inkjet printing operation on the workpiece at the inkjet printing station 14.

[0047] The displacement end of the material transfer assembly 30 is equipped with a vision inspection device 31 and a gripping mechanism 32. The vision inspection device 31 is used to perform vision inspection on the workpiece, thereby assisting the gripping mechanism 32 in gripping and placing the workpiece.

[0048] Specifically, after the battery workpiece is manufactured, it is usually marked with information such as trademarks, parameters, and manufacturers on its surface. Traditional marking equipment or devices have a low degree of automation, and they cannot complete the marking work well, especially for some irregularly shaped batteries, resulting in errors such as tilting, blurring, and inconsistency in the marked information.

[0049] By setting up an automated material transfer component 30, and simultaneously installing a vision inspection device 31 and a gripping mechanism 32 at its displacement end, the vision inspection device 31 can perform visual inspection before or after gripping the workpiece to confirm its accurate placement. This allows the gripping mechanism 32 to determine the workpiece's position before gripping, enabling it to perform the gripping operation accurately. Furthermore, after moving the workpiece to the required placement position, a second visual inspection can be performed to ensure that its placement is not misaligned, allowing for more precise subsequent coding operations.

[0050] Secondly, the visual inspection operation includes image capture and position detection. The captured image is used to detect the position parameters of the workpiece. For example, visual algorithms are used to calculate the placement position, orientation, posture and other parameters of the workpiece, which can assist the gripping mechanism 32 in operating the workpiece.

[0051] Furthermore, the gripping mechanism 32 is configured as a vacuum nozzle, connected to an external vacuum generating device, thereby using vacuum negative pressure to grip the workpiece.

[0052] like Figure 2 and Figure 3 As shown, preferably, the material transfer assembly 30 is provided with a first robotic arm 33. The wrist joint at the farthest end of the first robotic arm 33 is provided with a first camera 34 and a first suction cup 35. The first suction cup 35 is used to transfer the workpiece from the feeding assembly 51 to the rotating assembly 20. The first camera 34 performs visual inspection on the workpieces on the feeding assembly 51 and the rotating assembly 20 respectively.

[0053] Specifically, to achieve efficient and accurate transfer of workpieces between the feeding assembly 51, the rotating assembly 20, and the discharging assembly 52 or the defective product assembly 53, the transfer assembly 30 is equipped with a first robotic arm 33 and a second robotic arm 36, each undertaking different stages of workpiece transfer and inspection tasks. The specific structure and operation of the first robotic arm 33 are described in detail below:

[0054] The first robotic arm 33, through the rotation and bending movements of its wrist joint, can adjust the posture of the first camera 34 and the first suction cup 35 to accurately perform visual inspection and grasp objects. The first camera 34 first performs visual inspection on the workpiece on the feeding assembly 51 to calculate the specific position parameters of the workpiece to be grasped, and then feeds them back to the central control system of the equipment (not shown in the figure). The central control system then drives the first robotic arm 33 according to the corresponding position parameters, and after adjusting the angle, the first suction cup 35 can accurately grasp the workpiece on the feeding assembly 51.

[0055] Then, the first robotic arm 33 is driven to operate, placing the gripped workpiece onto the corresponding fixed fixture 23 at the loading station 13. The robotic arm places the workpiece into the fixed fixture 23, which has an adsorption function. The adsorption function of the fixed fixture 23 can be used in conjunction with the robotic arm to adsorb and flatten the workpiece according to the preset position parameters.

[0056] Secondly, after placement, the first camera 34 can be used again to perform a second visual inspection on the workpiece placed on the fixed fixture 23 of the rotating component 20, thereby calculating whether the placement parameters of the workpiece are correct and whether there is any deviation. If there is a deviation, it can be fed back to the central control system in a timely manner, so that it drives the first robotic arm 33 to operate and uses the first suction cup 35 to readjust the placement of the workpiece to ensure that it is accurately placed in the preset position and the placement parameters are correct.

[0057] like Figure 2 and Figure 3 As shown, preferably, the transfer assembly 30 also includes a second robotic arm 36. A second camera 37 and a second suction cup 38 are respectively located at the wrist joint at the farthest end of the second robotic arm 36. The second suction cup 38 is used to transfer the workpiece out of the rotating assembly 20, and the second camera 37 performs visual inspection of the workpiece on the rotating assembly 20. Alternatively, the second suction cup 38 transfers the workpiece from the rotating assembly 20 to the discharge assembly 52, and the second camera 37 inspects the workpiece on the discharge assembly 52; or the second suction cup 38 transfers the workpiece from the rotating assembly 20 to the defective product assembly 53, and the second camera 37 inspects the workpiece on the defective product assembly 53.

[0058] Specifically, the structure and operation of the second robotic arm 36 are described in detail below. The second robotic arm 36, through the rotation and bending movements of its wrist joints, can adjust the posture of the second camera 37 and the second suction cup 38 to accurately perform visual inspection and object grasping operations. The second camera 37 first captures and detects the inkjet printing status on the workpiece. If the printing is correct, a good product signal is fed back, thereby driving the second robotic arm 36 to grasp the workpiece and place it in the unloading assembly 52. ​​If the printing is incorrect, a defective product signal is fed back, thereby driving the second robotic arm 36 to grasp the workpiece and place it in the defective product assembly 53.

[0059] Secondly, visual inspection is performed on the workpiece on the fixed fixture 23 of the rotating component 20 to calculate the specific position parameters of the workpiece waiting to be grasped. This information is then fed back to the central control system of the equipment, which drives the second robotic arm 36 according to the corresponding position parameters, enabling the second suction cup 38 to accurately grasp the workpiece on the fixed fixture 23. The second robotic arm 36 is then driven to place the grasped workpiece into the discharge component 52 or the defective product component 53.

[0060] Furthermore, after placement, the second camera 37 can be used again to perform a second visual inspection on the workpiece placed on the discharge assembly 52 or defective product assembly 53, thereby calculating whether the placement parameters of the workpiece are correct and whether there is any deviation. If there is a deviation, it can also be fed back to the central control system in a timely manner, so that it drives the second robotic arm 36 to operate and uses the second suction cup 38 to readjust the placement of the workpiece to ensure that it is accurately placed in the preset position and the placement parameters are correct.

[0061] like Figure 4 and Figure 5 As shown, preferably, the inkjet printing assembly 40 is provided with an inkjet printing bracket 42 and an inkjet printing host 41. The inkjet printing bracket 42 is installed on the frame 10 at the position corresponding to the inkjet printing station 14, and the inkjet printing host 41 is installed on the inkjet printing bracket 42, so as to perform inkjet printing operation on the workpiece placed on the fixed fixture 23 at the inkjet printing station 14.

[0062] Specifically, the inkjet printer bracket 42 is also provided with an adjusting shaft 43 and a mounting base 44. The inkjet printer host 41 is mounted on the mounting base 44 and is slidably connected to the inkjet printer bracket 42 through the mounting base 44. The adjusting shaft 43 is set as a threaded shaft and cooperates with the threaded hole (not shown in the figure) of the mounting base 44 to form a threaded transmission connection. Thus, the rotation of the adjusting shaft 43 can adjust the relative position relationship between the mounting base 44 and the inkjet printer bracket 42, thereby adjusting the interval size between the inkjet printer host 41 and the fixed fixture 23 to accommodate workpieces of different thicknesses to be inkjet printed.

[0063] Secondly, the printhead of the inkjet printer 41 can also be configured to rotate left and right for a certain amount of fine movement, thereby making a certain amount of fine adjustment according to the placement position of the workpiece on the fixed fixture 23, so as to make the printing position and content more accurate. If the placement parameters of the workpiece on the fixed fixture 23 exceed the preset fine movement range of the inkjet printer 41, the inkjet printer 41 will not work and will feed back defective product information to the central processing system, so that the second robotic arm 36 will put it into the defective product assembly 53, waiting to enter the defective product processing flow. By adjusting the distance between the inkjet printer 41 and the fixed fixture 23 through the adjusting shaft 43 and the mounting base 44, in conjunction with the fine adjustment function of the printhead, it can be ensured that workpieces of different thicknesses can obtain accurate printing effects.

[0064] like Figures 2 to 4 As shown, preferably, the rotating assembly 20 is provided with an indexing plate 21, and a plurality of fixed fixtures 23 are evenly spaced on the indexing plate 21, so that the workpiece is rotated and transported under the drive of the indexing plate 21.

[0065] Specifically, for example, four fixed fixtures 23 can be set up to carry and transport the workpieces, so that the workpieces pass through the loading station 13, the inkjet printing station 14, and the unloading station 15 in sequence to complete the entire inkjet printing operation process. In addition, a debugging station 16 can be set up to facilitate manual loading and unloading debugging operations during the debugging phase.

[0066] like Figure 3 As shown, preferably, the rotating assembly 20 is further provided with a rotating joint 22, and the fixing fixture 23 is provided with a vacuum suction cup 24. One end of the rotating joint 22 is connected to an external vacuum generating device, and the other end is connected to the vacuum suction cup 24.

[0067] Specifically, to achieve stable fixation of the workpiece, a vacuum suction cup 24 is installed on the fixing fixture 23. The strong adsorption capacity of the vacuum suction cup 24 is used to firmly adsorb the workpiece onto the fixing fixture 23. In order to ensure the normal operation of the vacuum suction cup 24 and the stability of the equipment, a rotary joint 22, a sponge buffer pad 25 and an air pump silencer 26 can also be installed.

[0068] Since the indexing plate 21 needs to be rotatable, a pneumatic rotary joint 22 can be installed at the position of the rotation axis of the indexing plate 21. The rotary joint 22 can be used to realize the rotational delivery of negative pressure airflow, thereby driving the rotating vacuum suction cup 24 on the indexing plate 21. The air source generated by the external vacuum generating equipment is preferably 0.5-0.7MPa compressed air.

[0069] like Figure 6 As shown, preferably, the fixing fixture 23 is further provided with a sponge buffer pad 25, which is installed on the adsorption end of the vacuum suction cup 24.

[0070] Specifically, the sponge cushioning pad 25 can provide cushioning assistance to the workpiece, while also reducing adsorption marks on the workpiece surface and improving the final quality of the product.

[0071] like Figure 6 As shown, preferably, the fixing fixture 23 is further provided with an air pump silencer 26, which is installed on the vacuum suction cup 24.

[0072] Specifically, the air pump silencer 26 is typically composed of sound-absorbing materials such as sound-absorbing cotton and sound-absorbing panels. These materials effectively absorb and disperse noise waves, thereby reducing noise interference to the surrounding environment and personnel. They can be installed at the inlet and outlet of the air pump or vacuum suction cup 24, effectively reducing the instantaneous burst sound during gas flow, thus lowering the noise level of the air pump or vacuum suction cup 24 during operation. It also prevents backflow from the air pump or vacuum suction cup 24, avoiding operational instability or equipment damage caused by backflow. The air pump silencer 26 also prevents harmful substances such as asbestos dust from being discharged from the air pump or vacuum suction cup 24, protecting the working environment and ensuring that the cleanliness of the equipment's interior meets the required standards.

[0073] like Figure 1 As shown, preferably, an air filtration unit 12 is also installed above the frame 10 to provide clean air to the inside of the equipment.

[0074] Specifically, the air filtration unit 12 can adopt the existing FFU fan filter unit, whose fan can draw in air from the top of the frame 10, and after filtration, form clean air that is discharged into the equipment, so that the cleanliness of the equipment reaches the Class 1000 requirement, and optimize the operation of the equipment and the effect of coding.

[0075] The frame 10 is also equipped with an operation panel 11 for controlling the operating parameters of the automatic inkjet printer and viewing the current working data of the equipment. The feeding component 51, the discharging component 52, and the defective product component 53 can be loaded and unloaded manually, or they can be automated using external cooperating devices according to process requirements, and all operations are controlled by a central control system.

[0076] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
