When the baffle plate is in the blocking position, it can block the corresponding position of the battery cell to be blocked; when the baffle plate is in the idle position, it can avoid the corresponding position of the battery cell to be blocked; and a first driving device for driving the baffle plate to switch between the blocking position and the idle position. During the painting process, the paint mist is blocked by the baffle plate and cannot reach the blocked position, thus creating a blank area. After painting is completed, the baffle plate can be driven to the idle position for maintenance or to scrape off any waste paint adhering to it.

Description

Technical Field

[0001] This application relates to the field of battery processing equipment technology, and more specifically, to a paint-blocking mechanism. Background Technology

[0002] A battery cell generally consists of a battery casing and a battery cell housed inside the casing. The battery cell is the core component of the battery cell and is composed of a positive electrode, a negative electrode, a separator, and an electrolyte. The battery casing is the outermost protective structure of the battery cell, serving to house and protect the internal components.

[0003] To ensure the safe and stable operation of individual battery cells, insulation is typically applied to the outside of the battery casing. During charging and discharging, the electrodes of a battery cell carry a high voltage. Insulation effectively prevents current conduction between the battery casing and external conductors, preventing short circuits and avoiding serious safety issues such as performance degradation, overheating, or even fire and explosion.

[0004] One existing insulation treatment method involves spraying insulating varnish onto the outer surface of the battery casing. However, due to the rounded corners of the battery casing, the insulating varnish cannot be evenly applied at the junction of the outer surface (especially the rounded corners) and the end face where the terminal post is located, which can easily lead to insulation failure. Therefore, the current practice is to leave a blank area of ​​appropriate width (i.e., not sprayed with insulating varnish) near the end face where the terminal post is located during the insulating varnish application. This blank area is then insulated and protected by an insulating film to overcome the defect of uneven coating.

[0005] Then, the current blank area is protected from the spraying of insulating varnish by applying paint-blocking tape. After the insulating varnish is sprayed, the paint-blocking tape is removed, and then an insulating film is applied in the same spot. This method of creating the blank area is inefficient. In addition, in some painting scenarios, battery cells are supported on a carrier for painting, and the sprayed paint mist can easily contaminate the carrier, affecting its positioning accuracy.

[0006] Therefore, how to shield the corresponding positions of the battery to prevent paint mist from being sprayed on those positions is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the purpose of this application is to provide a paint blocking mechanism to block the corresponding position and prevent paint mist from being sprayed on the position.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] The first aspect of this application provides a paint-blocking mechanism, comprising:

[0010] First support structure;

[0011] A shield is movably disposed on the first support body, and includes at least a shielding position and an idle position. When the shield is in the shielding position, it can shield the corresponding position of the battery cell to be shielded. When the shield is in the idle position, it can avoid the corresponding position of the battery cell to be shielded.

[0012] A first driving device is used to drive the shield to switch between the shielded position and the idle position.

[0013] The paint-blocking mechanism provided in this application, when used to cover blank areas, can drive a shielding plate to the blocking position via a first driving device. In this position, the shielding plate can block the corresponding position of the battery cell at the painting station. During the painting process, the paint mist is blocked by the shielding plate and cannot reach the blocked area, thus creating a blank area. After painting is completed, the shielding plate can be driven to an idle position for maintenance or to remove any waste paint. Since the battery cell at the painting station is supported by the carrier below it, the shielding plate also blocks the carrier, preventing paint mist from being sprayed onto it and avoiding the problem of affecting the support accuracy due to waste paint on the carrier.

[0021] This application discloses a paint-blocking mechanism to shield a corresponding position and prevent paint mist from being sprayed onto that position.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] This application discloses a paint-blocking mechanism that can shield corresponding parts. Those skilled in the art can select the placement of the paint-blocking mechanism based on the location of the battery cell that needs to be shielded. Taking the blank area of ​​the battery cell as an example, the blank area is usually placed on the side of the battery cell near the cover plate (i.e., the side where the terminal post is located).

[0024] Insulating varnish is sprayed onto individual battery cells in a paint booth. Each cell is fixed to a carrier and transported to the painting station via a conveyor mechanism, where the painting equipment sprays the corresponding surfaces of the battery cells. If a blank area is required for the battery cell, the paint-blocking mechanism can be used to shield this area, preventing paint mist from adhering to it. Similarly, if the carrier beneath the battery cell needs to be shielded, the paint-blocking mechanism can be used to shield it. Of course, the shielding location can be other than these; those skilled in the art can determine the appropriate location based on the design requirements of the battery product.

[0025] like Figures 1-3 As shown, the paint blocking mechanism 100 disclosed in this application includes a paint blocking body 130, which includes a first support 131, a shielding plate 132, and a first driving device 133. The first support 131 serves as a support for the shielding plate 132 and the first driving device 133, and at least provides an installation base for the shielding plate 132.

[0026] The baffle 132 is movably mounted on the first support 131. The movement of the baffle 132 is not limited; it can be a moving motion, a rotating motion, or a combined motion that includes both moving and rotating motion.

[0027] The baffle 132 can change its position through its movement. The position of the baffle 132 includes at least a blocking position and an idle position. The baffle 132 can produce different effects when it is in different positions.

[0028] The blocking position of the shielding plate 132 is its working position, meaning that when the shielding plate 132 is in the blocking position, it can block the corresponding position of the battery cell 200 to be blocked. It should be noted that whether the shielding plate 132 can block the required position when it moves to the blocking position also depends on the overall installation position of the paint blocking mechanism 100 at the corresponding workstation.

[0029] When the shield 132 is in the idle position, it avoids obstructing the corresponding position of the battery cell 200 to be shielded. When the shield 132 is in the idle position, other related work can be performed, including but not limited to maintenance of the shield 132 and scraping off any waste paint adhering to its surface. The reason for moving the shield 132 to the idle position before performing maintenance and waste paint removal is that when the shield 132 is in the shielding position, the distance to the battery cell 200 is too close, making maintenance and waste paint removal inconvenient.

[0030] The first driving device 133 is used to drive the baffle 132 to switch between a blocked position and an idle position. Different types of first driving devices 133 can be selected depending on the movement mode of the baffle 132. For example, when the baffle 132 moves linearly, the first driving device 133 can be a linear motor, a cylinder, a hydraulic cylinder, etc.; when the baffle 132 moves rotaryly, the first driving device 133 can be a motor, a rotary motor, etc.

[0031] In summary, the paint-blocking mechanism 100 disclosed in this application, when used to block blank areas, can drive the shielding plate 132 to the blocking position via the first driving device 133. At this time, the shielding plate 132 can block the corresponding position of the battery cell 200 at the painting station. During the painting process, the paint mist is blocked by the shielding plate 132 and cannot reach the blocked position, thus forming a blank area. After painting is completed, the shielding plate 132 can be driven to an idle position for maintenance or to scrape off any waste paint adhering to it. Since the battery cell 200 at the painting station is supported by the carrier below it, the shielding plate 132 can also block the carrier, preventing paint mist from being sprayed onto the carrier and avoiding the problem of waste paint adhering to the carrier, which could affect the support accuracy.

[0032] In one specific embodiment of this application, the shielding plate 132 is rotatably supported on the first support body 131 via a rotating shaft, and the shielding plate 132 can rotate about the axis of the rotating shaft as the center of rotation. The first driving device 133 is connected to the rotating shaft to drive the shielding plate 132 to rotate, so that the shielding plate 132 switches between a shielding position and an idle position.

[0033] Specifically, the first driving device 133 may include a drive motor, and in order to reduce the rotation speed of the baffle 132, the first driving device 133 may also include a reducer. After the drive motor is reduced in speed by the reducer, it drives the rotating shaft to rotate, and then drives the baffle 132 to rotate.

[0034] When the shield 132 rotates to the shielding position, it is located on the side of the rotation axis closer to the battery cell 200, ensuring that the shield 132 is close to the battery cell 200 while maintaining a set distance. This set distance cannot be too large, otherwise the shielding effect cannot be guaranteed. When the shield 132 rotates to the shielding position, the lower part of the shield 132 is blocked, preventing the spraying of paint mist. This creates a blank area on the lower part of the battery cell 200 below the shield 132, and also ensures that the vehicle below the battery cell 200 is not contaminated with waste paint, keeping it clean.

[0035] When the baffle 132 is rotated to its idle position, it is located on the side of the rotation axis away from the battery cell 200. Therefore, even though the baffle 132 is far from the battery cell 200, it does not function as a barrier to the blank area or the vehicle when in its idle position. This position, being far from the battery cell 200, allows for manual or automatic scraping of any excess paint from the baffle 132. Because of this distance, the excess paint will not be transferred to the battery cell 200 during maintenance or cleaning.

[0036] The blocking position and the idle position of the baffle 132 can be spaced 180° apart. That is, when the baffle 132 is in the blocking position and you want to switch to the idle position, you only need to drive the baffle 132 to rotate 180° (half a turn). When the baffle 132 is in the idle position and you want to switch to the blocking position, you only need to drive the baffle 132 to rotate 180° (half a turn).

[0037] It should be noted that when the blocking plate 132 switches between the blocked position and the idle position by rotating, the width of the blank area is adjusted by adjusting the stopping angle of the blocking plate 132. Figure 3 For example, the blank area shown is the area below the shield 132 where the battery casing is located. To increase the width of the blank area, the shield 132 needs to be rotated upwards, which moves the intersection of the shield 132 and the battery casing upwards, thus increasing the width of the blank area. To decrease the width of the blank area, the shield 132 needs to be rotated downwards, which moves the intersection of the shield 132 and the battery casing downwards, thus decreasing the width of the blank area.

[0038] Furthermore, the thickness of the shield 132 gradually decreases from the rotation axis to the edge of the shield 132. That is, in this embodiment, the edge of the shield 132 is thinner, and the side closer to the rotation axis is thicker. This arrangement allows the rotation axis to connect with the thicker part of the shield 132, improving the reliability of the connection. When the shield 132 is in the shielding position, the thinner edge of the shield 132 points towards the battery cell 200, providing a more precise shielding effect and preventing the situation where the width of the blank area cannot be precisely controlled due to the thicker edge of the shield 132.

[0039] The included angle between the two surfaces of the baffle 132 along its thickness direction can be between 20° and 45°. The included angle between the two surfaces of the baffle 132 along its thickness direction reflects the slope of the thickness change of the baffle 132. In this embodiment, controlling the included angle between 20° and 45° ensures that the maximum thickness of the baffle 132 guarantees the stability of the rotating shaft, and also prevents the width of the baffle 132 from being too large, even when the edge thickness of the baffle 132 is relatively thin, thus minimizing the space occupied by the baffle 132 during rotation.

[0040] For example, the included angle between the two surfaces of the shield 132 along the thickness direction can be 20°, 25°, 30°, 35°, 40°, 45°, etc.

[0041] Furthermore, when the shielding plate 132 is in the shielding position, the upper surface of the shielding plate 132 along the thickness direction is parallel to the horizontal plane. That is, in this embodiment, the upper surface of the shielding plate 132 is horizontal and perpendicular to the surface of the battery cell 200 to be painted. When the painting equipment sprays paint above the shielding plate 132, the upper surface of the shielding plate 132 plays the main role in blocking the paint. Its upper surface is horizontal and perpendicular to the surface of the battery casing to be painted, which can ensure a more accurate width of the blank area. This prevents the problem that the actual blank area width is greater than the set blank area width due to the upper surface of the shielding plate 132 forming an obtuse angle with the surface to be painted; it also prevents the problem that the actual blank area width is less than the set blank area width due to the upper surface of the shielding plate 132 forming an acute angle with the surface to be painted.

[0042] To improve painting efficiency, in one specific embodiment of this application, two masking plates 132 are symmetrically arranged along the rotation axis, i.e., the two masking plates 132 are spaced 180° apart. For ease of understanding, the two masking plates 132 are defined as the first masking plate and the second masking plate, respectively. When the first masking plate is in the masking position, the second masking plate is in the idle position; when the second masking plate is in the masking position, the first masking plate is in the idle position. When the first masking plate is in the masking position, blocking the blank area and / or the waiting area of ​​the vehicle, the second masking plate can be maintained or cleaned with scraped paint in the idle position. After the battery group is painted and the waste paint on the second masking plate is cleaned, the rotation axis can be driven to rotate 180° to switch the positions of the first and second masking plates, so that the second masking plate blocks the blank area and / or the waiting area of ​​the vehicle in the masking position, and the first masking plate cleans up waste paint in the idle position.

[0043] In this embodiment, the two baffles 132 are symmetrically arranged along the rotation axis, ensuring high positioning accuracy of the two baffles 132 with each rotation switch. Since the two baffles 132 are 180° symmetrical, it is only necessary to control the rotation angle of the rotation axis to be consistent each time, which can ensure that the area to be left blank is accurately covered during the flipping process, ensuring the consistency and regularity of the blank space, avoiding the situation where paint covers areas that should not be painted, thereby improving the painting quality of the product.

[0044] The cyclical design of the two masking plates 132 saves waiting time when the masking plates 132 are scraping paint. Simply rotating the shaft 180° switches the cleaned masking plate 132 to the paint-blocking position, allowing masking work to continue. This greatly improves the continuity and efficiency of the painting operation, making it especially suitable for large-volume, repetitive painting jobs. In other words, while one masking plate 132 is masking and painting, the other masking plate 132 can be scraping paint, achieving synchronous operation. This parallel operation method effectively utilizes time, reduces overall working time, and increases painting output per unit time.

[0045] The two baffles 132 can be a single integrated structure or a detachable connection structure. This embodiment does not limit the connection relationship between the two baffles 132. There are two rotating shafts, each located at one end of a baffle 132, and they are integral with the baffles 132. The rotating shafts can be made of the same material as the baffles 132 or different materials. This embodiment does not limit the materials of the baffles 132 and the rotating shafts.

[0046] In one specific embodiment of this application, the paint-blocking mechanism may further include a paint-scraping component 120, which is used to scrape off waste paint from the masking plate 132 when it is in an idle position. In this embodiment, by scraping off the residual waste paint on the masking plate 132 in a timely manner by the paint-scraping component 120, the interference of paint mist during the painting process can be effectively reduced. If the residual waste paint is not cleaned, paint mist may rebound when painting continues, affecting the uniformity and smoothness of the paint spraying. By scraping and cleaning, the surface of the masking plate 132 can be kept relatively clean, reducing paint mist interference and making the painted surface smoother and more delicate. The waste paint will not cause the blank area to widen due to the increased thickness of the masking plate 132.

[0047] In one specific embodiment of this application, the paint scraping assembly 120 includes a second support body 126, a paint scraping part 125, and a second driving device. The paint scraping part 125 is slidably fitted onto the second support body 126, and the sliding direction of the paint scraping part 125 is parallel to the extending direction of the baffle plate 132. This ensures that no matter where the paint scraping part 125 slides, it maintains the same positional relationship with the baffle plate 132 when it is in an idle position, and the distance between them will not change due to sliding.

[0048] The paint scraping unit 125 has a paint scraping groove 1252. When the masking plate 132 is in the paint scraping mode, it extends into the paint scraping groove 1252. The second driving device is used to drive the paint scraping unit 125 to reciprocate. During the paint scraping process, the masking plate 132 needs to extend into the paint scraping groove 1252 so that the inner wall of the paint scraping groove 1252 can be in contact with the surface of the masking plate 132 with waste paint. During the paint scraping process, the second driving device drives the paint scraping unit 125 to move from one end of the masking plate 132 to the other end, completing one scraping of the masking plate 132. Depending on the needs of paint scraping, the masking plate 132 in the idle position can be scraped only once, or the paint scraping unit 125 can be moved back and forth to perform two paint scraping processes. Of course, as needed, the paint scraping unit 125 can be driven to move back and forth multiple times to perform more paint scraping processes. In this embodiment, the number of paint scraping processes is not limited.

[0049] The shape formed by the upper and lower sidewalls of the paint scraper groove 1252 is adapted to the cross-sectional shape of the baffle plate 132 to ensure that the upper and lower sidewalls of the paint scraper groove 1252 can effectively fit against the upper and lower surfaces of the baffle plate 132, respectively. In this embodiment, the inner wall of the paint scraper groove 1252 fits against the baffle plate 132, ensuring a large contact area with the waste paint on the surface of the baffle plate 132 during the paint scraping process, thereby efficiently removing the waste paint. Compared with some partial contact paint scraping methods, this comprehensive fitting method ensures that the entire surface of the baffle plate 132 with waste paint can be cleaned, leaving no dead corners and ensuring the integrity of the paint scraping effect.

[0050] The paint scraping method, in which the paint scraper groove 1252 moves in contact with the baffle plate 132, ensures that the scraping force applied to all parts of the baffle plate 132 surface is relatively uniform. The shape and size of the inner wall of the paint scraper groove 1252 are relatively fixed, resulting in stable pressure applied to the baffle plate 132 during movement. This helps to ensure a uniform degree of paint scraping on the surface of the baffle plate 132, avoiding localized over- or under-scraping, thus guaranteeing the consistency of the surface condition of the baffle plate 132 during subsequent use.

[0051] Waste paint generated during spray painting operations, if discharged arbitrarily, can cause serious pollution to soil and water bodies. In this embodiment, the paint scraper 125 also has a paint storage device 1251, which is located below the paint scraper groove 1252 and is used to store the waste paint scraped off by the paint scraper groove 1252. The paint storage device 1251 can be a tank structure with its opening facing upwards, so that the waste paint scraped off by the paint scraper 125 can fall into the paint storage device 1251 and be collected by it.

[0052] The paint storage device 1251 can collect waste paint, preventing it from directly flowing into the environment, reducing damage to the surrounding ecological environment, helping to protect the environment, and complying with environmental protection regulations. The collected waste paint can be further processed and recycled. After specific processing, some waste paint can be reused in spray painting operations or other related fields, improving the utilization rate of insulating paint, reducing resource waste, and lowering production costs.

[0053] Furthermore, if the waste paint scraped off by the paint scraper 125 is not collected in time, it will scatter and drip onto the work area, affecting the normal operation of related equipment and increasing the risk of equipment failure. The paint storage device 1251 can effectively collect the scraped waste paint, keep the work area clean, and help improve production efficiency and product quality. Moreover, it avoids the corrosion of equipment by waste paint, reduces equipment maintenance costs, and extends the service life of the equipment.

[0054] Furthermore, in this embodiment, the second driving device may include a drive motor 121 and a transmission belt mechanism. The transmission belt mechanism includes a driving pulley 122, a driven pulley 124, and a transmission belt 123. The driving pulley 122 and the driven pulley 124 are both supported on the second support body 126. The transmission belt 123 is drivenly connected to the driving pulley 122 and the driven pulley 124. The paint scraping part 125 is fixed to the transmission belt 123. The drive motor 121 is drivenly connected to the driving pulley 122.

[0055] The drive motor 121 may be equipped with a reducer to reduce its output speed. The drive motor 121 drives the drive pulley 122 to rotate, thereby causing the transmission belt mechanism to operate. Since the paint scraper 125 is fixed on the transmission belt 123, it can be moved. The direction of movement of the paint scraper 125 varies depending on the rotation direction of the drive pulley 122.

[0056] Belt drives have buffering and vibration-absorbing properties, thus enabling the paint scraping unit 125 to operate more smoothly during reciprocating movement. This helps to avoid affecting the paint scraping effect due to vibration and impact during transmission, ensuring the uniformity and stability of the paint scraping, and preventing problems such as uneven scratches or damage to the surface of the masking plate 132 caused by shaking during the paint scraping process.

[0057] When a sudden overload occurs during the paint scraping process (such as a localized protrusion or foreign object obstructing the scraping), the belt drive will slip. This slippage actually serves as overload protection, preventing damage to components in the transmission system due to overload, protecting the entire equipment, and extending its service life.

[0058] The drive belts used in belt drive mechanisms are generally inexpensive and have a relatively long service life, resulting in low replacement costs. Compared to some high-end transmission components (such as high-precision gears), they effectively reduce equipment operating costs. Furthermore, due to their simple structure, maintenance and repair costs are also relatively low.

[0059] The maintenance of the drive belt mechanism is relatively simple. Routine maintenance mainly includes checking the tension and wear of the drive belt 123, and cleaning debris from the surfaces of the driving pulley 122 and driven pulley 124. These maintenance tasks do not require specialized technicians or complex tools; operators can perform them after simple training, enabling them to promptly identify and resolve potential problems and ensure the normal operation of the equipment.

[0060] In one specific embodiment of this application, the paint blocking mechanism 100 may further include a support device 110 and a displacement driving device. At least one of the first support body 131 and the second support body 126 is driven by the displacement driving device to slide along the support device 110, and the sliding direction is the arrangement direction of the first support body 131 and the second support body 126. In this embodiment, by designing at least one of the first support body 131 and the second support body 126 as movable, the paint scraping part 125 and the baffle plate 132 can be controlled to move closer to each other and further away from each other as needed to adjust the distance between them. This ensures that the paint scraping part 125 does not interfere with the movement of the baffle plate 132, while also allowing the paint scraping part 125 to approach the baffle plate 132 and scrape off the waste paint on the baffle plate 132.

[0061] In this embodiment, the first support 131 and the second support 126 can both slide on the support device 110. There can be two displacement driving devices, which are used to drive the first support 131 and the second support 126 to reciprocate, respectively, and the movement directions of the first support 131 and the second support 126 are parallel.

[0062] For ease of understanding, the displacement driving device that drives the first support 131 to move is defined as the first displacement driving device, and the displacement driving device that drives the second support 126 to move is defined as the second displacement driving device.

[0063] The first displacement driving device can drive the first support body 131 to move the baffle plate 132, thereby adjusting the distance between it and the battery cell 200 to be painted, so as to ensure the accuracy of the blank area width and avoid the problem that the blank area width is greater than or less than the designed blank area width due to the distance between the baffle plate 132 and the battery cell 200 to be painted being too large or too small.

[0064] The second displacement drive device can drive the second support body 126 to move the paint scraper 125, thereby adjusting the distance between the paint scraper 125 and the baffle plate 132. For example, before the paint scraper 125 rotates, the paint scraper 125 needs to move away from the baffle plate 132 to ensure that the paint scraper 125 does not interfere with the rotation of the baffle plate 132; when paint scraping is required, the paint scraper 125 needs to move closer to the baffle plate 132 so that the paint scraper 125 can fit against the baffle plate 132 and scrape off the waste paint on the baffle plate 132.

[0065] To ensure that the movement directions of the first support 131 and the second support 126 do not deviate, in this embodiment, the paint-blocking mechanism 100 may further include a guide rail assembly 140. The guide rail assembly 140 includes a guide rail and a slider that slides with the guide rail. The guide rail is disposed on the support device 110, and sliders are disposed on both the first support 131 and the second support 126. In this embodiment, the movement directions of the first support 131 and the second support 126 are constrained by the sliding engagement of the slider and the guide rail. The movement directions of the two are related to the extension direction of the guide rail. Those skilled in the art can set the extension direction of the guide rail according to requirements so that the first support 131 and the second support 126 move in the corresponding direction.

[0066] In one specific embodiment of this application, the paint-blocking mechanism 100 may further include a first protective cover and a second protective cover. The first protective cover is disposed on the outside of the first driving device 133, and the second protective cover is disposed on the outside of the second driving device. The shape and structure of the first and second protective covers are not limited; there may be only one, or multiple covers may be provided according to the structural characteristics of the first and second driving devices to achieve shielding and protection for both devices.

[0067] During the painting process, a large amount of paint mist fills the paint booth, which easily adheres to the surfaces of the first drive unit 133 and the second drive unit. The first and second protective covers act as a barrier, preventing the paint mist from directly contacting the equipment and thus preventing it from adhering to the first and second drive units and affecting their operation. They also prevent the chemical components in the paint mist from corroding and damaging the first and second drive units, extending the equipment's service life.

[0068] With the first and second protective covers installed, cleaning becomes much easier. Workers only need to clean the exterior of the first and second protective covers, eliminating the need for complex internal cleaning, significantly reducing the workload and time required.

[0069] Unless the context explicitly indicates an exception, words such as "a," "an," "a kind," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list; a method or apparatus may also include other steps or elements.
