Description

Technical Field

[0001] This application relates to the field of lithium battery production equipment technology, specifically to an inkjet marking device. Background Technology

[0002] In the lithium battery production process, inkjet printing equipment is often used to mark battery electrodes in real time, such as marking defective parts of the film material. Because the ink used in inkjet printing equipment has a short drying time, ink remaining at the ink outlet of the printhead or in the ink supply line can easily come into contact with air and dry during marking intervals or when the equipment is stopped, forming solidified blockages. This can lead to problems such as poor ink flow or even printhead or ink path blockage. Therefore, manual unblocking is often required, but this method affects production progress and efficiency. Utility Model Content

[0003] The main technical problem this application addresses is to provide an inkjet marking device that can automatically seal the ink outlet and reduce the probability of printhead clogging.

[0004] One embodiment provides an inkjet marking device, including a frame and a marking mechanism, wherein the marking mechanism includes a loading component, an inkjet component, a sealing component, a first driving component, a second driving component, and a third driving component; wherein:

[0005] The loading component is connected to the frame; the first driving component is disposed on the loading component and connected to the inkjet component; the first driving component is used to drive the inkjet component to move relative to the loading component along a first path;

[0006] The second driving member is disposed on the loading member, and the third driving member is connected between the second driving member and the sealing member; the second driving member is used to drive the third driving member to move the sealing member relative to the loading member along a second path parallel to the first path; the third driving member is used to drive the sealing member to rotate relative to the inkjet component in a plane perpendicular to the first path, so as to close or open the ink outlet of the inkjet component.

[0007] In one embodiment, the sealing element includes a rotating seat and a sealing gasket, one end of the rotating seat being coupled to the power end of the third driving member; the sealing gasket is disposed at the other end of the rotating seat and is used to abut against the inkjet component to seal and close the ink outlet.

[0008] In one embodiment, the first drive member includes a slide cylinder, and / or the third drive member includes a swing cylinder.

[0009] In one embodiment, the loading component includes a guide plate, a connecting plate, a spacer plate, and a connecting seat. The guide plate and the connecting plate are spaced apart and opposite to each other. The spacer plate is connected between the guide plate and the connecting plate. One of the first driving member and the second driving member is disposed on the side of the connecting plate close to the guide plate, and the other is disposed on the side of the connecting plate away from the guide plate. The connecting seat is disposed on the side of the guide plate away from the connecting plate, and the connecting seat is connected to the frame.

[0010] In one embodiment, the frame includes a support frame and a guide rail, the support frame having two support arms arranged side by side at intervals, the guide rail connecting the two support arms, and the loading component slidably connected to the guide rail.

[0011] In one embodiment, the inkjet marking device further includes an air blowing mechanism, the frame further includes a support arm, two support arms are arranged in parallel and spaced apart in a first direction, the support arm is connected to the support arm, and the support arm and the guide rail are arranged side by side and spaced apart in a second direction, and the air blowing mechanism is disposed on the support arm; wherein, the first direction is perpendicular to the second direction.

[0012] In one embodiment, the inkjet marking device further includes a control component electrically connected to the first drive member, the second drive member, the third drive member, the inkjet element, and the air blowing mechanism.

[0013] In one embodiment, a positioning component is provided between the guide rail and the support arm. The positioning component includes a first positioning seat and a second positioning seat. The first positioning seat is locked to the support arm in a manner that allows it to move along the support arm. The second positioning seat is fixed to the guide rail and is locked to the first positioning seat in a manner that allows it to rotate relative to the first positioning seat.

[0014] In one embodiment, there are multiple marking mechanisms arranged side by side along the guide rail.

[0015] In one embodiment, the inkjet marking device further includes a drive mechanism; the drive mechanism is connected in cooperation with the marking mechanism and is used to drive the marking mechanism to move along the guide rail.

[0016] According to the inkjet marking device of the above embodiment, the anti-clogging structure is formed by the cooperation of the second driving member, the third driving member, and the seal. The seal can automatically close or open the ink outlet of the inkjet unit, effectively reducing the probability of clogging at the ink outlet or ink path. It also significantly improves the automation level of the inkjet marking device, helping to reduce the cost of manual wiping, cleaning, and maintenance, and improving the utilization rate and production efficiency of the device. For example, on the one hand, during marking intervals or downtime, closing the ink outlet of the inkjet unit with the seal can automatically isolate residual ink from the external air, thereby effectively reducing the probability of clogging due to ink drying upon contact with air. On the other hand, the second driving member drives the seal to move, which not only avoids structural interference between the seal and the inkjet unit and the marked object during the process of closing or opening the ink outlet, reducing the accuracy requirements for seal installation and positioning, but also works with the first driving member to ensure the seal tightly abuts against the inkjet unit, enhancing the sealing effect of the ink outlet.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] Please see Figures 1 to 7 This application provides an inkjet marking device that can be used in lithium battery production lines to mark film materials such as battery electrodes. For example, by coordinating with a detection device, it can inkjet mark defective areas of the electrode detected by the detection device, so that the defective areas can be removed in subsequent processes. The inkjet marking device includes a frame 100, a marking mechanism 200, an air blowing mechanism 300, a control component 400, and other functional components as needed.

[0032] Please see Figure 1 and Figure 2 The frame 100 primarily serves as a mounting platform for other components of the inkjet marking device, such as the marking mechanism 200 and the air blowing mechanism 300. The frame 100 allows the entire inkjet marking device to be arranged within the lithium battery production line. For example, the marking mechanism 200 is mounted on the frame 100 and positioned above the object to be marked (e.g., film materials such as battery electrode sheets) to complete inkjet marking as the object passes through it on the conveyor belt. The air blowing mechanism 300 is mounted on the frame 100 and positioned downstream of the marking mechanism 200 in the conveyor belt direction of the object to be marked, so that the ink at the marking location dries quickly by blowing air onto the object.

[0033] Please combine Figure 7 The control component 400 is electrically connected to the marking mechanism 200 and the air blowing mechanism 300. The control component 400 can be understood as a collection of related devices that implement some or all of the functions of the inkjet marking device. For example, the control component 400 may include a PLC controller with a pre-stored control program. The control component 400 can be used to achieve linkage between the marking mechanism 200 and the air blowing mechanism 300, as well as linkage between the inkjet marking device and other functional devices on the lithium battery production line. For example, the control component 400 can control the marking mechanism 200 to start or stop the marking operation. When marking is detected by the marking mechanism 200 (e.g., at the end of a single marking cycle), the control component 400 controls the air blowing mechanism 300 to blow air, ensuring that the ink sprayed on the marked object dries within a preset time (e.g., 0.8 seconds).

[0034] In some embodiments, please refer to Figures 3 to 5 The marking mechanism 200 includes an inkjet assembly, an anti-clogging assembly, and a loading component 210. The inkjet assembly is mainly used to spray ink onto the object to be marked for marking. The anti-clogging assembly is mainly used to seal the ink outlet of the inkjet assembly during marking intervals or downtime to prevent ink remaining in the ink outlet or ink path from contacting the outside air. The inkjet assembly and the anti-clogging assembly are mounted on the loading component 210, which is connected to the frame 100, thus mounting the marking mechanism 200 as a whole on the frame 100. The details are described below.

[0035] Please see Figure 4 and Figure 5The inkjet assembly includes a first drive unit 220 and an inkjet unit 230. The inkjet unit 230 can be understood as a collection of printheads, ink cartridges, and related components. The inkjet unit 230 is electrically connected to the control component 400 to start and stop inkjet printing under the control of the control component 400. The first drive unit 220 is a power device or power mechanism capable of outputting linear motion. The first drive unit 220 is disposed on the loading member 210 and connected to the inkjet unit 230 (specifically, the printhead). For example, the first drive unit 220 is electrically connected to the control component, and the power end of the first drive unit 220 is coupled to the inkjet unit 230.

[0036] The first driving component 220 can drive the inkjet component 230 to move linearly relative to the loading component 210, so as to adjust the relative position between the ink outlet of the inkjet component 230 and the object to be marked. On the one hand, it maintains a preset marking distance between the ink outlet and the object to be marked during the marking process, and on the other hand, it cooperates with the anti-clogging component to seal the ink outlet during the marking gap or after the marking is completed.

[0037] For example, the first driving component 220 includes a slide cylinder. Utilizing the characteristics of low and controllable pneumatic pressure, short stroke, and high precision, the slide cylinder not only enables precise control of the movement stroke and dwell position of the inkjet unit 230, but also helps to reduce the size of the inkjet assembly and enhance its structural compactness. Of course, depending on actual needs, the first driving component 220 can also employ other suitable devices, such as electric cylinders or linear motors, which will not be elaborated upon here.

[0038] Please see Figure 4 and Figure 5 The anti-blocking assembly includes a second drive member 240, a third drive member 250, and a seal member 260. The second drive member 240 employs a power device or mechanism capable of outputting linear motion, such as a cylinder, electric cylinder, or linear motor electrically connected to the control assembly. The third drive member 250 employs a power device or mechanism capable of outputting rotary motion, such as a swing cylinder or motor electrically connected to the control assembly. The second drive member 240 is disposed on the loading member 210, and the third drive member 250 is connected between the second drive member 240 and the seal member 260. For example, the power end of the second drive member 240 is coupled to the body of the third drive member 250, and the power end of the third drive member 250 is coupled to the seal member 260.

[0039] The second drive member 240 can drive the third drive member 250 to move the seal 260 linearly relative to the loading member 210. The movement paths of the third drive member 250 and the seal 260 are set to be parallel to the movement path of the inkjet component 230. For easier distinction and description, please refer to [link to relevant documentation]. Figure 4The movement path of the inkjet component 230 is defined as the first path L1, and the movement paths of the third drive component 250 and the seal component 260 are defined as the second path L2.

[0040] The third drive member 250 can drive the seal 260 to rotate relative to the inkjet component 230 in a plane perpendicular to the first path L1 and the second path L2, so that the seal 260 can close or open the inkjet nozzle of the inkjet component 230. For example, the third drive member 250 includes a swing cylinder, which drives the seal 260 to reciprocate within a 90-degree angular stroke.

[0041] Using the object to be marked as a reference, during the marking operation, the second drive member 240 drives the third drive member 250 to move the seal member 260 upward along the second path L2 to a position relatively far away from the object to be marked; the first drive member 220 drives the inkjet member 230 downward along the first path L1 to a position relatively close to the object to be marked; so that the position of the ink outlet of the inkjet member 230 is lower than the position of the seal member 260 (i.e., the ink outlet is closer to the object to be marked), and then the inkjet member 230 can perform the inkjet marking operation.

[0042] After the marking operation is completed (e.g., after a single marking cycle or during shutdown), the second drive component 240 drives the third drive component 250 to move the seal 260 downward along the second path L2, and the first drive component 220 drives the inkjet component 230 to move upward along the first path L1, so that the seal 260 is positioned lower than the ink outlet of the inkjet component 230. Subsequently, the third drive component 250 drives the seal 260 to rotate below the ink outlet (i.e., the seal 260 covers the ink outlet on the first path L1). Finally, the first drive component 220 drives the inkjet component 230 to move slightly downward, or the second drive component 240 drives the seal 260 to move slightly upward, so that the seal 260 tightly abuts against the inkjet component 230, thereby sealing the ink outlet. It can be understood that executing the reverse motion process will open the ink outlet with the seal 260.

[0043] Firstly, the anti-clogging component formed by the second drive component 240, the third drive component 250, and the seal 260 can automatically seal the ink outlet of the inkjet unit 230 during marking intervals or downtime. This isolates residual ink in the ink outlet or ink path of the inkjet unit 230 from the outside air, preventing the residual ink from drying and solidifying due to air contact, thus reducing the probability of clogging or poor ink flow. This eliminates the need for frequent manual wiping and cleaning of the inkjet unit 230, effectively improving the automation level of the inkjet marking device. This not only significantly reduces manual maintenance costs but also increases the utilization rate of the device, supporting improved production efficiency.

[0044] Secondly, by driving the seal 260 to move up and down along the second path L2 through the second driving component 240, not only can structural interference between the seal 260 and the inkjet component 230 and the object being marked be avoided during the process of the seal 260 closing or opening the ink outlet, but it can also compensate for the movement error of the seal 260 or the inkjet component 230, thereby reducing the precision requirements for the installation and movement of the seal 230 and the inkjet component 230.

[0045] For example, during the marking process, the second drive component 240 drives the seal 260 to move upward and stop above the ink outlet, which provides ample space for the inkjet component 230 to perform inkjet marking action, and avoids the seal 260 from affecting the marking operation and marking effect.

[0046] For example, during the process of opening or closing the ink outlet, the second driving member 240 drives the seal 260 to move, which can compensate for the movement error of the seal 260 or the inkjet component 230, so as to position the relative position between the seal 260 and the inkjet component 230 (specifically the ink outlet). This ensures that the seal 260 is firmly against the inkjet component 230 to seal the ink outlet, and also promotes the formation of a suitable separation distance between the seal 260 and the inkjet component 230, so as to support the smooth rotation of the seal 260.

[0047] In some embodiments, please refer to Figure 5 The sealing element 260 includes a rotating seat 261 and a sealing gasket 262. The rotating seat 261 may be a strip structure, and its length dimension is greater than the distance between the first path L1 and the second path L2. One end of the rotating seat 261 in the length direction is coupled to the power end of the second driving element 250, for example, one end of the rotating seat 260 is fixed to the power end of the swing cylinder. The sealing gasket 262 may be made of a soft material such as rubber or a material with a certain elasticity. The sealing gasket 262 is disposed at the other end of the rotating seat 260 in the length direction, for example, the sealing gasket 262 is locked on the surface of the rotating seat 261 facing the ink outlet.

[0048] Thus, by driving the rotating seat 261 to rotate via the third driving member 250, the sealing gasket 262 can be transferred onto the first path L1, so that the sealing gasket 262 and the ink outlet face each other along the first path L1. Then, by driving the sealing gasket 262 and the inkjet component 230 to move closer together along the first path L1 via the second driving member 240 or the first driving member 220, the sealing gasket 262 and the ink outlet end face of the inkjet component 230 can be tightly fitted (it can also be understood that the sealing gasket 262 is essentially clamped between the rotating seat 261 and the inkjet component 230), thereby achieving a seal for the ink outlet. Based on the material properties of the sealing gasket 262, the sealing effect on the ink outlet can be effectively enhanced.

[0049] In some embodiments, please refer to Figures 1 to 3 and Figure 6 The frame 100 includes a support frame 110, a guide rail 120, and a load-bearing arm 130. The support frame 110 is a rectangular frame structure. For ease of distinction and description, the two frame arms of the support frame 110 arranged side by side in the first direction are defined as support arms 111, and the two frame arms of the support frame 110 arranged side by side in the third direction are defined as crossbeam arms 112. The guide rail 120 is parallel to the crossbeam arms 112 and connected between the two support arms 111. The load-bearing arm 130 is arranged side by side with the guide rail 120 in the second direction, and the two opposite ends of the load-bearing arm 130 in the first direction are respectively connected to the corresponding support arms 111.

[0050] It should be noted that the first, second, and third directions in this article are three mutually perpendicular directions defined based on the structural form of the rack 100, in order to describe the inkjet marking device more clearly and in detail; in some scenarios, such as Figure 1 , Figure 2 and Figure 6 The inkjet marking device shown can be categorized as follows: the first direction can refer to the left-right direction of the inkjet marking device; the second direction can refer to the front-back direction of the inkjet marking device or the direction of the tape travel of the object being marked (such as film materials like battery electrodes); and the third direction can refer to the up-down direction or the vertical direction of the inkjet marking device.

[0051] Among them, the support frame 110 serves as the support carrier for the inkjet marking device, and the inkjet marking device can be fixedly installed in a preset position in the lithium battery production line through the support frame 110; for example, a support seat 113 can be set on the crossbeam arm 112 located below in the third direction, and the inkjet marking device can be fixed in the preset position by the support seat 113; the marking mechanism 200 (specifically the loading component 210) is connected to the guide rail 120 so that the marking mechanism 200 can be suspended and installed on the support frame 110 through the guide rail 120; and the air blowing mechanism 300 is set on the support arm 130. For example, the air blowing mechanism 300 includes an air source and an air nozzle connected by an air passage, and the air nozzle is set on the support arm 130.

[0052] Thus, the object to be marked can be positioned below the marking mechanism 200 and the air blowing mechanism 300 in the third direction, and travel along the second direction through the inkjet marking device. During the travel of the object, the inkjet assembly performs inkjet marking on the object located below it, and the air blowing mechanism 300 blows air onto the object to allow the ink sprayed on the object to dry quickly, thereby improving the efficiency of the inkjet marking operation. Furthermore, the frame 100, constructed by combining the support frame 110, guide rail 120, and load-bearing arm 130, effectively reduces the overall structural complexity of the inkjet marking device, improving the flexibility of its assembly, disassembly, and application. Additionally, components such as the support arm 111, crossbeam arm 112, guide rail 120, and load-bearing arm 130 can be made of aluminum alloy profiles to ensure that the frame 100 has sufficient structural rigidity and load-bearing capacity.

[0053] In other embodiments, the frame 100 may also adopt other suitable structural forms. For example, the support frame 110 may be a U-shaped frame or gantry structure composed of two support arms 111 and a crossbeam arm 112; or the support frame 110 may be a U-shaped frame or gantry structure composed of two support arms 111 and a guide rail 120; or the load-bearing arm 130 and the air blowing mechanism 300 may be omitted. All of these are acceptable as long as they provide the necessary assembly space for the marking mechanism 200 and meet the marking operation requirements, and will not be elaborated further here.

[0054] In some embodiments, please refer to Figures 3 to 5 The loading component 210 includes a guide plate 211, a connecting plate 212, a spacer plate 213, and a connecting seat 214; wherein the guide plate 211 and the connecting plate 212 are arranged opposite each other at a distance, for example, they are opposite each other at a distance in a second direction; the spacer plate 213 is connected between the guide plate 211 and the connecting plate 212, for example, the spacer plate 213 has a preset length in the second direction so that the guide plate 211 and the connecting plate 212 maintain a stable distance.

[0055] The first driving member 220 and the second driving member 240 are disposed on opposite sides of the connecting plate 212. For example, the first driving member 220 is disposed on the side of the connecting plate 212 away from the guide plate 211 in the second direction, and the second driving member 240 is disposed on the side of the connecting plate 212 closer to the guide plate 211 in the second direction. The connecting plate 212 allows the inkjet assembly and the anti-clogging assembly to be assembled together, while also creating a stable gap between them to prevent structural interference during their movement. For example, the first path L1 and the second path L2 are located on opposite sides of the connecting plate 212, and their direction or extension direction can be a third direction (i.e., the vertical direction).

[0056] The connecting seat 214 is located on the side of the guide plate 211 away from the connecting plate 212 in the second direction. For example, the connecting seat 214 is fixed to the top of the guide plate 211 in the third direction. The connecting seat 214 is connected to the frame 100 (specifically, the guide rail 120), thereby mounting the marking mechanism 200 on the frame 100 in an approximately suspended manner.

[0057] Therefore, by designing the structure of the loading component 210, the structural space of the loading component 210 can be fully utilized, effectively enhancing the structural compactness of the marking mechanism 200. At the same time, the loading component 210 can create a certain gap between the inkjet assembly (along with the anti-clogging assembly) and the frame 100 (specifically the guide rail 120), which helps to reduce the difficulty of disassembling and assembling the marking mechanism 200.

[0058] In some embodiments, please refer to Figures 3 to 5 The connecting seat 214 can be a sliding structure, and the loading component 210 is slidably connected to the guide rail 120 through the connecting seat 214. In this way, taking advantage of the structural feature that the marking mechanism 200 can slide along the guide rail 120, the position of the marking mechanism 200 on the guide rail 120 can be adjusted according to the marking needs; for example, before the marking operation, the marking mechanism 200 can be adjusted to the corresponding position and locked according to the position of the part to be marked.

[0059] In some embodiments, the inkjet marking device also includes a drive mechanism, which is mainly used to drive the marking mechanism 200 to reciprocate along the guide rail 120 within a preset stroke, so as to automatically adjust the position of the marking mechanism 200 on the guide rail 120 according to the position of the marking part, thereby reducing manual intervention and improving the automation level of the inkjet marking device.

[0060] For example, the drive mechanism includes a drive motor, a transmission rack, and a transmission gear; wherein the transmission rack is disposed parallel to the guide rail 120 on the support frame 110, the drive motor is disposed on the loading component 210 (e.g., guide plate 212) and electrically connected to the control component, and the transmission gear is fixed to and meshes with the power end of the drive motor and the transmission rack. Thus, based on the sliding connection between the connecting seat 214 and the guide rail 120 and the meshing relationship between the transmission gear and the transmission rack, the entire marking mechanism can be driven to reciprocate along the guide rail 120 by means of the drive motor, thereby realizing the automatic adjustment of the position of the marking mechanism 200.

[0061] In some embodiments, please refer to Figure 2 and Figure 6The marking mechanism 200 is configured to be multiple, arranged side-by-side along the guide rail 120. For example, two marking mechanisms 200 are spaced apart on the front side of the guide rail 120 in the second direction, and two marking mechanisms 200 are spaced apart on the rear side of the guide rail 120 in the second direction. By setting multiple marking mechanisms 200, the working range of inkjet marking can be effectively increased, and the marking efficiency can be improved.

[0062] Specifically, multiple marking mechanisms 200 can be set up independently. For example, before the marking operation, each marking mechanism 200 can be locked in its corresponding position on the guide rail 120. Multiple marking mechanisms 200 can also be set up in conjunction. For example, each of the multiple marking mechanisms 200 has a corresponding drive mechanism, which drives the marking mechanism 200 to reciprocate along the guide rail 120 within its respective travel range.

[0063] In some embodiments, please refer to Figure 2 and Figure 3 The frame 100 also includes a positioning assembly 140, which is connected between the guide rail 120 and the support arm 111. Specifically, the positioning assembly 140 includes a first positioning seat 141 and a second positioning seat 142. The first positioning seat 141 is locked to the support arm 111 in a way that allows it to move upward along the support arm 111 in a third direction. For example, the first positioning seat 141 is slidably connected to the support arm 111 and locked to the support arm 111 by fasteners such as screws. The second positioning seat 142 is fixedly connected to the guide rail 120 and is locked to the first positioning seat 141 in a way that allows it to rotate relative to the first positioning seat 141. For example, the second positioning seat 142 is stacked on top of the first positioning seat 141. The second positioning seat 142 is provided with an arc-shaped groove through it. Fasteners such as screws pass through the arc-shaped groove through the second positioning seat 142 and connect to the first positioning seat 141, thereby locking the first positioning seat 141 and the first positioning seat 141.

[0064] Based on the first positioning seat 141, the combined structure of the positioning component 140, the guide rail 120 and the marking mechanism 200 can move along the support arm 111 to adjust and fix the height position of the marking mechanism 200 in the third direction. For example, before the marking operation, the marking mechanism 200 can be adjusted to the corresponding height position according to the height position of the object being marked, so that the inkjet nozzle is as close as possible to the object being marked, which can effectively reduce the travel distance of the inkjet component 230 on the first path L1.

[0065] Please see Figure 3Based on the second positioning seat 142, the combined structure of the second positioning seat 142, the guide rail 120 and the marking mechanism 200 can rotate around the rotation axis L3 in the first direction, thereby realizing the adjustment and fixation of the spray angle of the inkjet component 230; for example, by adjusting the spray angle of the inkjet component 230, it can adapt to different belt travel angles of the marked object.

[0066] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
