Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a waste paint collection 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. A painting robot sprays varnish onto one side of the battery casing, but the varnish mist sprayed by the robot extends beyond the battery casing, polluting the environment and wasting the insulating varnish.

[0005] Therefore, how to collect the insulating varnish that has not been sprayed onto the surface to be sprayed is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a waste paint collection mechanism for collecting insulating paint that has not been sprayed on the surface to be sprayed.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A first aspect of this application provides a waste paint collection mechanism for being arranged on the side of a battery to be painted, away from the painting equipment, the waste paint collection mechanism comprising:

[0009] Support frame;

[0010] At least two drive rollers are rotatably arranged on the support frame, and each drive roller is arranged in parallel and spaced apart.

[0011] A collection belt is driven to each of the drive rollers, and at least one of the drive rollers is a drive wheel to drive the collection belt to move. The collection belt is configured to face the battery to be painted at the painting station.

[0012] The waste paint collection mechanism provided in this application is positioned on the side of the battery to be painted at the spray painting station, away from the spray painting equipment. When the spray painting equipment sprays paint onto the battery, some paint mist that is not applied to the battery is sprayed onto the waste paint collection mechanism, which collects this paint mist. The collection belt of the waste paint collection mechanism is used to collect waste paint, specifically the paint mist that is not applied to the battery, which is sprayed onto the side of the collection belt facing the battery. The collection belt is tensioned and driven by various drive rollers. After the side facing the battery is completely covered with waste paint, the rotation of the drive rollers moves the paint-covered portion of the collection belt to the side away from the battery, while the uncovered portion moves back to the side facing the battery, allowing for continued waste paint collection. The waste paint on the surface of the collection belt can be scraped off, which allows for centralized recycling and reuse of the waste paint, and also cleans the surface of the collection belt in preparation for the next waste paint collection.

Detailed Implementation

[0026] This application discloses a waste paint collection mechanism for collecting insulating paint that has not been sprayed onto the surface to be sprayed.

[0027] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0028] like Figures 1-3 As shown in the figure, this application discloses a waste paint collection mechanism 100, which is used to be arranged in the battery 200 to be painted (e.g., Figure 7The side of the battery 200 away from the painting equipment (not shown in the figure). The battery casing of the battery to be painted needs to be coated with insulating varnish in the paint booth. Taking the large-area painting of the battery casing as an example, multiple batteries 200 to be painted are transported by a conveying device to the waste paint collection mechanism 100 and the painting equipment in the paint booth. The painting equipment sprays paint in the direction of the battery 200 to be painted, and some paint mist will pass over the battery 200 to be painted and be sprayed onto the waste paint collection mechanism 100, so that the waste paint collection mechanism 100 can collect the insulating varnish that is not sprayed on the battery 200 to be painted, which is convenient for recycling.

[0029] In this embodiment, the waste paint collection mechanism includes a support frame 110, drive rollers 130, and a collection belt 120. There are at least two drive rollers 130, rotatably arranged on the support frame 110, such that each drive roller 130 can rotate around its axis. The drive rollers 130 are arranged in parallel and at intervals, and the farthest distance between the drive rollers 130 is related to the area of ​​waste paint collected by the collection belt 120.

[0030] For ease of understanding, the following description will use only two drive rollers 130 as an example. Those skilled in the art will understand that there may be more than two drive rollers 130. For example, several other drive rollers 130 may be set between the two drive rollers 130 to improve the transmission effect on the collection belt 120.

[0031] Taking two drive rollers 130 as an example, the greater the distance between the two drive rollers 130, the larger the area of ​​waste paint collected by the collection belt 120; conversely, the smaller the distance between the two drive rollers 130, the smaller the area of ​​waste paint collected by the collection belt 120. Those skilled in the art can select the distance between the two drive rollers 130 based on the number of batteries 200 to be painted simultaneously, ensuring that the collection belt 120 can cover each battery 200 to be painted, guaranteeing that the insulating paint not applied to each battery 200 can be collected by the collection belt 120 during painting.

[0032] The collection belt 120 is driven by various drive rollers 130, forming a belt drive mechanism. At least one of the drive rollers 130 is a driving roller to move the collection belt 120, which is configured to face the battery 200 to be painted. To reduce costs, one of the two drive rollers 130 is a driving roller, and the other is a driven roller. The driving roller can be driven by a drive device such as a drive motor to rotate, thereby moving the collection belt 120, which in turn drives the driven roller to rotate.

[0033] The collecting belt 120 has a ring structure, with its inner side connected to two drive rollers 130. The outer side of the collecting belt 120 is the surface for capturing paint mist. The material of the collecting belt 120 can be metal or non-metal. In this embodiment, the material of the collecting belt 120 is not limited, as long as the outer surface of the collecting belt 120 is smooth and can easily scrape off the captured waste paint.

[0034] For example, the axial direction of the two drive rollers 130 can be arranged perpendicular to the horizontal plane, so that the collection belt 120 moves in a direction parallel to the horizontal plane. The width of the collection belt 120 (i.e., the dimension perpendicular to the arrangement direction of the two drive rollers 130, i.e., the dimension along the height direction) can be designed according to requirements, as long as it can prevent waste paint from crossing the collection belt 120 along the height direction and maximize the collection of waste paint.

[0035] The waste paint collection mechanism 100 disclosed in this application is arranged on the side of the battery 200 to be painted, away from the painting equipment, so that when the painting equipment sprays paint onto the battery 200, some paint mist that is not sprayed onto the battery 200 will be sprayed onto the waste paint collection mechanism 100, which collects some of the paint mist. The collection belt 120 of the waste paint collection mechanism 100 is used to collect waste paint, that is, paint mist that is not sprayed onto the battery 200 will be sprayed onto the surface of the collection belt 120 facing the battery 200. The collection belt 120 is tensioned and driven by two drive rollers 130. After the side of the collection belt facing the battery 200 to be painted is completely covered with waste paint, the rotation of the drive rollers 130 moves the paint-covered portion of the collection belt 120 away from the battery 200, while the uncovered portion moves back to the side facing the battery 200, thus continuing the collection of waste paint. The waste paint on the surface of the collection belt 120 can be scraped off, allowing for centralized recycling and cleaning of the surface in preparation for the next waste paint collection.

[0036] In one specific embodiment of this application, the conveying direction of the collecting belt 120 is parallel to the conveying direction of the batteries 200 to be painted. In other words, the arrangement direction of the two drive rollers 130 is parallel to the arrangement direction of each battery 200 to be painted at the painting station, that is, the conveying direction of the large surface of the collecting belt 120 is parallel to the arrangement direction of each battery 200 to be painted. The large surface of the collecting belt 120 refers to the portion of the collecting belt 120 between the two drive rollers 130. If the large surface of the collecting belt 120 closer to the battery 200 to be painted moves to the left, then the large surface of the collecting belt 120 farther from the battery 200 to be painted moves to the right.

[0037] Along the painting direction, the projection of the battery 200 to be painted onto the plane of the collection belt 120 all fall within the coverage area of ​​the collection belt 120, ensuring that the paint mist passing over the battery 200 to be painted can be captured by the collection belt 120 close to the battery 200 as much as possible.

[0038] In this embodiment, the support frame 110 includes a support frame body and roller support frames 113 disposed at both ends of the support frame body. The roller support frames 113 have support holes that mate with the drive shaft of the drive roller 130. The drive roller 130 is rotatably mounted on the roller support frame 113. The drive roller 130 may include a drive shaft and a roller rotatably sleeved on the drive shaft. The drive shaft of the drive roller 130 is inserted into the support hole of the support frame 110, thus enabling the drive roller 130 to be mounted on the support frame 110.

[0039] As the collection belt 120 is used for an extended period, it will stretch and deform, causing it to lose sufficient friction with the two drive rollers 130, thus affecting its transmission. In one specific embodiment of this application, at least one roller support frame 113 has a support hole that is a first strip-shaped adjustment hole 1131, allowing the drive shaft of the drive roller 130 that mates with the first strip-shaped adjustment hole 1131 to be adjusted as needed within the first strip-shaped adjustment hole 1131. If the collection belt 120 becomes loose, the position of the drive shaft within the first strip-shaped adjustment hole 1131 can be changed, i.e., the distance between the two drive rollers 130 can be increased to maintain the tension of the collection belt 120.

[0040] To facilitate tensioning of the collection belt 120, the waste paint collection mechanism 100 disclosed in this embodiment also includes a tensioning device. The tensioning device is connected to the transmission roller 130 that cooperates with the first strip-shaped adjustment hole 1131 to push the transmission roller 130 to move away from the other transmission roller 130.

[0041] Furthermore, the extending direction of the first strip-shaped adjustment hole 1131 is parallel to the conveying direction of the collecting belt 120 (the conveying direction of the large surface of the collecting belt 120). It should be noted that there is a certain angle between the extending direction of the first strip-shaped adjustment hole 1131 and the conveying direction of the collecting belt 120 (i.e., the arrangement direction of the two drive rollers 130), as long as the angle between the two is not 90°.

[0042] For ease of understanding, in this embodiment, the transmission roller 130 that cooperates with the first strip-shaped adjustment hole 1131 is defined as the adjustment roller. In this embodiment, the support hole on one roller support frame 113 is the first strip-shaped adjustment hole 1131, and the support hole on the other roller support frame 113 is a round hole. That is, the position of one transmission roller 130 is adjustable, while the position of the other transmission roller 130 is fixed and cannot be adjusted.

[0043] In this embodiment, the tensioning device can be a reset elastic element, one end of which is fixed to the support frame 110, and the other end abuts against the drive shaft of the adjusting roller. The reset elastic element can be a spring or an assembly including a spring, as long as the elastic force of the reset elastic element can act on the drive shaft of the adjusting roller, pushing the adjusting roller to move away from the other drive roller 130. The elastic force of the reset elastic element needs to be sufficient to tension the collecting belt 120.

[0044] The tensioning device can also be a threaded component. A threaded hole is provided on the support frame 110, and the threaded component is threaded into the threaded hole. The end of the threaded component abuts against the drive shaft of the adjusting roller. After the collecting belt 120 slips, the threaded component can be rotated, causing the threaded component to push the adjusting roller away from the other drive roller 130, so as to tension the collecting belt 120.

[0045] The threaded component can also be threaded into the drive shaft, i.e., a threaded hole for the threaded component is provided on the drive shaft, and an axial limiting hole for the threaded component is provided on the roller support frame 113. The threaded component rotates within the axial limiting hole, and the axial limiting hole restricts the axial movement of the threaded component. When the threaded component rotates, its axial displacement is limited by the axial limiting hole, so it can only rotate. Furthermore, because the threaded component is threaded into the threaded hole on the drive shaft, its rotation can drive the drive shaft to move axially along the threaded component. In this embodiment, rotating the threaded component pulls the adjusting roller away from the other drive roller 130 to tension the collecting belt 120.

[0046] In one specific embodiment of this application, the main body of the support frame includes an upper support 111, a lower support 114, and an intermediate support 112. The upper support 111 and the lower support 114 can be plate structures and are arranged in parallel. Of course, the upper support 111 and the lower support 114 can also be profile structures, rod structures, etc., and this embodiment does not limit the structure of the upper support 111 and the lower support 114.

[0047] There are multiple intermediate supports 112, which are connected at intervals between the upper support 111 and the lower support 114. The upper support 111, the lower support 114, and the intermediate supports 112 form a frame structure. The number of intermediate supports 112 is not limited. Two intermediate supports 112 can be selected and arranged at the ends of the upper support 111 and the lower support 114 to ensure the end strength of the upper support 111 and the lower support 114.

[0048] The roller support frame 113 includes an upper support and a lower support arranged in parallel. The upper support is fixed to the upper support body 111, and the lower support is fixed to the lower support body 114. The drive roller 130 is rotatably supported between the upper and lower supports. The upper support extends beyond the upper support body 111, and the lower support extends beyond the lower support body 114, making the upper and lower supports a cantilever beam structure to provide space for installing the drive roller 130. The drive roller 130 is confined between the upper and lower supports. During installation, first insert the drive shafts extending from both ends of the drive roller 130 into the support holes of the upper and lower supports, respectively. Then, fix the upper support to the upper support body 111 with fasteners, and fix the lower support to the lower support body 114 with fasteners. This ensures that the drive roller 130 is constrained between the upper and lower supports and cannot fall off. When the drive roller 130 is damaged and needs replacement or maintenance, simply disassemble one of the upper or lower supports to remove the drive roller 130.

[0049] like Figure 4 and Figure 5 As shown, in a specific embodiment of this application, the waste paint collection mechanism 100 may further include a main mounting body 150, and the support frame 110 may further include a bottom connecting frame 115. The bottom connecting frame 115 is connected to the bottom of the support frame body and is mounted on the main mounting body 150 by a first fastener. That is, in this embodiment, the support frame 110 is fixed to the main mounting body 150 by utilizing the bottom connecting frame 115 at its bottom. In this embodiment, by setting the main mounting body 150, all other components of the waste paint collection mechanism 100 except for the main mounting body 150 are directly or indirectly mounted on the main mounting body 150. With this configuration, when installing the waste paint collection mechanism 100 in the paint booth, the main mounting body 150 can be installed at the corresponding position in the paint booth, thus realizing the installation of the waste paint collection mechanism 100 in the paint booth. Similarly, when it is necessary to remove the waste paint collection mechanism 100, only the main mounting body 150 can be removed to completely remove the waste paint collection mechanism 100.

[0050] The bottom connecting bracket 115 is provided with a second strip-shaped adjustment hole 1151 for the first fastener to pass through, and the second strip-shaped adjustment hole 1151 extends in the direction close to and away from the battery 200 to be painted. In this embodiment, when the support bracket 110 is installed onto the main mounting body 150, the first fastener passes through the second strip-shaped adjustment hole 1151 and is screwed into the threaded hole of the main mounting body 150, thus completing the fixation of the support bracket 110 on the main mounting body 150.

[0051] Because the fastening hole on the bottom connecting frame 115 that mates with the first fastener is a strip-shaped hole (i.e., the second strip-shaped adjustment hole 1151), the position of the support frame 110 is adjustable. Furthermore, because the collecting belt 120 is mounted on the support frame 110, its position is also adjustable. Those skilled in the art can adjust the distance between the collecting belt 120 and the battery 200 to be painted based on the effect of the collecting belt 120 in intercepting paint mist. During adjustment, simply loosen the first fastener, move the support frame 110, and tighten the first fastener when the collecting belt 120 is in the appropriate position.

[0052] In one specific embodiment of this application, along the painting direction, the distance between the collecting belt 120 and the battery 200 to be painted at the painting station is 20mm to 200mm. For example, the above distance can be 20mm, 40mm, 60mm, 80mm, 100mm, 120mm, 140mm, 160mm, 180mm, 200mm, etc. Those skilled in the art can select the specific distance value based on their needs.

[0053] like Figure 5 and Figure 6 As shown in a specific embodiment of this application, the waste paint collection mechanism 100 may further include a first paint scraping assembly 140, which can be fixed to the main mounting body 150. The first paint scraping assembly 140 includes a scraper 142, which is in contact with the collection belt 120. When the collection belt 120 is in operation, since the scraper 142 is in contact with the collection belt 120, the two will generate relative movement. As the collection belt 120 is in operation, the scraper 142 can scrape off the waste paint attached to the surface of the collection belt 120.

[0054] In this embodiment, the first paint scraping component 140 can promptly scrape away residual waste paint on the collection belt 120, keeping the surface of the collection belt 120 relatively clean and preventing excessive amounts of waste paint from dripping down and contaminating other components below the waste paint collection mechanism 100. This embodiment also uses the first paint scraping component 140 to periodically clean the waste paint from the surface of the collection belt 120, maintaining its cleanliness in preparation for continued paint mist interception. Furthermore, periodic cleaning of the waste paint facilitates its recycling.

[0055] Specifically, the first paint scraping assembly 140 may also include a scraper mounting bracket 141, with a scraper 142 mounted on the scraper mounting bracket 141. The scraper 142 can completely cover the collection belt 120 along the direction of movement perpendicular to the collection belt 120, so that any position at the height of the collection belt 120 can be scraped by the scraper 142, avoiding the existence of cleaning blind spots.

[0056] The scraper mounting bracket 141 is mounted on the main mounting body 150 by a second fastener, and the scraper mounting bracket 141 is provided with a third strip-shaped adjustment hole 1141 through which the second fastener passes, and the third strip-shaped adjustment hole 1141 extends in the direction of approaching and away from the collection belt 120.

[0057] Because the fastening hole on the scraper mounting bracket 141 that mates with the second fastener is a strip-shaped hole (i.e., the third strip-shaped adjustment hole 1141), the position of the scraper mounting bracket 141 is adjustable. Furthermore, because the scraper 142 is mounted on the scraper mounting bracket 141, the position of the scraper 142 is also adjustable. Those skilled in the art can adjust the adhesion between the scraper 142 and the collection belt 120 based on the waste paint removal effect of the scraper 142. During adjustment, simply loosen the second fastener, then move the scraper mounting bracket 141, and when the adhesion between the scraper 142 and the collection belt 120 is adjusted to a suitable position, tighten the second fastener.

[0058] Furthermore, to facilitate the collection of scraped waste paint, the first paint scraping assembly 140 may also include a first paint storage device 143. The first paint storage device 143 is disposed below the scraper 142 and is used to store the waste paint scraped by the scraper 142. The first paint storage device 143 can be an upward-opening tank structure, allowing the waste paint scraped by the scraper 142 to fall into and be collected by the first paint storage device 143.

[0059] The first paint storage device 143 can collect waste paint, preventing it from flowing directly 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.

[0060] Furthermore, if the waste paint scraped off by the scraper 142 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 first paint storage device 143 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.

[0061] In one specific embodiment of this application, the collection belt 120 is divided by the various drive rollers 130 into a first collection belt portion 121 closer to the battery 200 to be painted, and a second collection belt portion 122 farther away from the battery 200 to be painted. That is, in addition to the portion that is in contact with the two drive rollers 130, the collection belt 120 also includes the first collection belt portion 121 and the second collection belt portion 122. The first collection belt portion 121 and the second collection belt portion 122 are arranged in parallel, and the distance between the first collection belt portion 121 and the second collection belt portion 122 is the diameter of the drive rollers 130.

[0062] The scraper 142 may be provided only in one of the first collection belt section 121 and the second collection belt section 122; or the scraper 142 may be provided in both the first collection belt section 121 and the second collection belt section 122. It should be noted that when there are multiple scrapers 142, they may originate from one first paint scraping assembly 140 or from multiple first paint scraping assemblies 140.

[0063] The dimension of the collecting belt 120 along the axial direction of the drive roller 130 is larger than the dimension of the battery 200 to be painted at the painting station along the axial direction of the drive roller 130. Taking the large surface of the collecting belt 120 as perpendicular to the horizontal plane as an example, the dimension of the collecting belt 120 along the height direction is larger than the height of the battery 200 to be painted, so that the collecting belt 120 can cover the height range of the battery 200 to be painted.

[0064] like Figure 7 and Figure 8 As shown in the embodiments, this application also discloses a waste paint collection system, which includes a waste paint collection mechanism 100, which is the waste paint collection mechanism disclosed in the above embodiments. Since it has the above-described waste paint collection mechanism, it possesses all the technical effects of the aforementioned waste paint collection mechanism, and will not be elaborated further here.

[0065] The waste paint collection system disclosed in this application may further include a paint-blocking mechanism 300, which is located on the side of the battery 200 to be painted that is closer to the painting equipment. When the painting equipment sprays paint onto the battery 200, some paint mist is sprayed onto the surface of the battery's casing, and some passes over the battery and lands on the collection belt 120. A portion of the paint mist falls due to gravity before reaching the battery, and this portion is intercepted by the paint-blocking mechanism 300.

[0066] The waste paint collection system disclosed in this embodiment includes a waste paint collection mechanism 100 and a paint blocking mechanism 300, capable of collecting waste paint from different locations. The waste paint collection mechanism 100 can collect waste paint sprayed behind the battery 200 to be painted; the paint blocking mechanism 300 can collect waste paint sprayed in front of the battery 200 to be painted and falling due to gravity. This configuration maximizes the collection of unused paint mist in the paint booth, reduces pollution to the surrounding environment, and also improves the recycling efficiency of waste paint.

[0067] The paint blocking mechanism 300 disclosed in this application includes a paint blocking body 330, which includes a first support 331, a baffle plate 332, and a first driving device 333. The first support 331 is a support device for the baffle plate 332 and the first driving device 333, and is at least used to provide an installation base for the baffle plate 332.

[0068] The baffle plate 332 is rotatably mounted on the first support 331 via a rotating shaft. The baffle plate 332 can change its position through its movement, and its position includes at least a blocked position and an idle position. Different positions of the baffle plate 332 produce different effects. The first driving device 333 can be a motor, etc., used to drive the baffle plate 332 to rotate, switching between the blocked and idle positions. For example, the first driving device 333 may include a drive motor. To reduce the rotational speed of the baffle plate 332, the first driving device 333 may also include a speed reducer. After the drive motor is reduced in speed by the speed reducer, it drives the rotating shaft to rotate, which in turn drives the baffle plate 332 to rotate.

[0069] The blocking position of the shielding plate 332 is its working position, meaning that when the shielding plate 332 is in the blocking position, it can block the corresponding position of the battery 200 to be painted. It should be noted that whether the shielding plate 332 can block the required position when it moves to the blocking position also depends on the overall installation position of the paint blocking mechanism 300 at the corresponding workstation.

[0070] When the shield 332 is in the idle position, it avoids obstructing the corresponding position of the battery 200 to be painted. When the shield 332 is in the idle position, other related work can be performed, including but not limited to maintenance of the shield 332 and scraping off any waste paint adhering to its surface. The reason for moving the shield 332 to the idle position before performing maintenance and waste paint removal is that when the shield 332 is in the shielding position, the distance to the battery 200 to be painted is too close, making maintenance and waste paint removal inconvenient.

[0071] The paint-blocking mechanism 300 disclosed in this application embodiment can be used to shield blank areas. Batteries 200 to be painted are coated with insulating varnish in a paint booth. Each battery 200 is fixed on a carrier and transported to the painting station via a conveying mechanism, where the painting equipment paints the corresponding surfaces of the batteries 200. If blank areas (i.e., parts that do not need to be painted) are required on the batteries 200, the paint-blocking mechanism can be used to shield these areas, preventing paint mist from adhering to them (simply by placing a shielding plate 332 on top of the blank areas). If it is necessary to shield the carrier below the battery cells, the paint-blocking mechanism 300 can shield the carrier below the batteries 200. Of course, the shielding location can also be other; those skilled in the art can determine the appropriate location based on the design requirements of the battery product by placing the paint-blocking mechanism 300 in the corresponding position.

[0072] When the paint blocking mechanism 300 is used to block the blank area, the first driving device 333 can drive the blocking plate 332 to the blocking position. At this time, the blocking plate 332 can block the corresponding position of the battery 200 to be painted at the painting station. During the painting process, the paint mist is blocked by the blocking plate 332 and cannot be sprayed to the blocked position, thus forming a blank area. After the painting is completed, the blocking plate 332 can be driven to an idle position for maintenance or scraping off the waste paint. Since the battery 200 to be painted at the painting station is supported by the carrier below it, the blocking plate 332 can also block the carrier, preventing paint mist from being sprayed on the carrier and avoiding the problem of waste paint on the carrier affecting the support accuracy.

[0073] When the shielding plate 332 rotates to the shielding position, it is located on the side of the rotating shaft closer to the battery 200 to be painted. This ensures that the shielding plate 332 is close to the battery 200 while maintaining a set distance. This set distance cannot be too large, otherwise the shielding effect cannot be guaranteed. When the shielding plate 332 rotates to the shielding position, the lower part of the shielding plate 332 is blocked, preventing the spraying of paint mist. This creates a blank area on the lower part of the battery 200 below the shielding plate 332, and also ensures that the carrier below the battery 200 is not contaminated with waste paint, keeping it clean.

[0074] When the baffle 332 is rotated to the idle position, it is located on the side of the rotation axis away from the battery 200 to be painted. Therefore, even though the baffle 332 is far from the battery 200, it does not function as a barrier to the blank area or the vehicle. This position allows for manual or automatic scraping of waste paint from the baffle 332, preventing waste paint from getting onto the battery 200 during maintenance or cleaning.

[0075] The blocking and idle positions of the baffle 332 can be spaced 180° apart. That is, when the baffle 332 is in the blocking position and you want to switch to the idle position, you only need to drive the baffle 332 to rotate 180° (half a turn). When the baffle 332 is in the idle position and you want to switch to the blocking position, you only need to drive the baffle 332 to rotate 180° (half a turn).

[0076] To improve painting efficiency, in one specific embodiment of this application, two masking plates 332 are symmetrically arranged along the rotation axis, i.e., the two masking plates 332 are spaced 180° apart. For ease of understanding, the two masking plates 332 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 pack 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.

[0077] In this embodiment, the two baffles 332 are symmetrically arranged along the rotation axis, ensuring high positioning accuracy of the two baffles 332 with each rotation switch. Since the two baffles 332 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.

[0078] The cyclical design of the two masking plates 332 saves waiting time when the masking plates 332 are scraping paint. Simply rotating the shaft 180° switches the cleaned masking plate 332 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 high-volume, repetitive painting jobs. In other words, while one masking plate 332 is masking and painting, the other masking plate 332 can be scraping paint, achieving synchronous operation. This parallel operation method effectively utilizes time, reduces overall working time, and increases paint output per unit time.

[0079] In one specific embodiment of this application, the paint-blocking mechanism may further include a second paint-scraping component 320, which is used to scrape off waste paint from the masking plate 332 in an idle position. In this embodiment, by promptly scraping off the residual waste paint on the masking plate 332 by the second paint-scraping component 320, 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 332 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 332.

[0080] In one specific embodiment of this application, the second paint scraping assembly 320 includes a second support body 326, a paint scraping part 325, and a second driving device. The paint scraping part 325 is slidably fitted onto the second support body 326, and the sliding direction of the paint scraping part 325 is parallel to the extending direction of the baffle plate 332. This ensures that no matter where the paint scraping part 325 slides, it maintains the same positional relationship with the baffle plate 332 when it is in an idle position, and the distance between them will not change due to sliding.

[0081] The paint scraping unit 325 has a paint scraping groove 3252. When the baffle plate 332 is in the paint scraping mode, it extends into the paint scraping groove 3252. The second driving device is used to drive the paint scraping unit 325 to reciprocate. During the paint scraping process, the baffle plate 332 needs to extend into the paint scraping groove 3252 so that the inner wall of the paint scraping groove 3252 can be in contact with the surface of the baffle plate 332 with waste paint. During the paint scraping process, the second driving device drives the paint scraping unit 325 to move from one end of the baffle plate 332 to the other end, completing one scraping of the baffle plate 332. Depending on the needs of paint scraping, the baffle plate 332 in the idle position can be scraped only once, or the paint scraping unit 325 can be moved back and forth to perform two scraping processes. Of course, as needed, the paint scraping unit 325 can be driven to move back and forth multiple times to perform more scraping processes. This embodiment does not limit the number of scraping processes.

[0082] The shape formed by the upper and lower sidewalls of the paint scraper groove 3252 is adapted to the cross-sectional shape of the baffle plate 332 to ensure that the upper and lower sidewalls of the paint scraper groove 3252 can effectively fit against the upper and lower surfaces of the baffle plate 332, respectively. In this embodiment, the inner wall of the paint scraper groove 3252 fits against the baffle plate 332, ensuring a large contact area with the waste paint on the surface of the baffle plate 332 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 332 with waste paint can be cleaned, leaving no dead corners and ensuring the integrity of the paint scraping effect.

[0083] In this embodiment, the paint scraping section 325 also has a second paint storage device 3251, which is disposed on the lower side of the paint scraping groove 3252 and is used to store the waste paint scraped off by the paint scraping groove 3252. The second paint storage device 3251 can be a tank structure with the opening facing upward, so that the waste paint scraped off by the paint scraping section 325 can fall into the second paint storage device 3251 and be collected by the second paint storage device 3251.

[0084] The second paint storage device 3251 can collect waste paint, preventing it from flowing directly 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 painting operations or other related fields, improving the utilization rate of insulating paint, reducing resource waste, and lowering production costs.

[0085] Furthermore, in this embodiment, the second driving device may include a drive motor 321 and a transmission belt mechanism. The transmission belt mechanism includes a driving pulley 322, a driven pulley 324, and a transmission belt 323. The driving pulley 322 and the driven pulley 324 are both supported on the second support body 326. The transmission belt 323 is drivenly connected to the driving pulley 322 and the driven pulley 324. The paint scraping part 325 is fixed to the transmission belt 323. The drive motor 321 is drivenly connected to the driving pulley 322.

[0086] The drive motor 321 may be equipped with a reducer to lower its output speed. The drive motor 321 drives the drive pulley 322 to rotate, thereby causing the transmission belt mechanism to operate. Since the paint scraper 325 is fixed on the transmission belt 323, it can be moved. The direction of movement of the paint scraper 325 varies depending on the rotation direction of the drive pulley 322.

[0087] Belt drives have buffering and vibration-absorbing properties, thus enabling the paint scraping unit 325 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 332 caused by shaking during the paint scraping process.

[0088] When a sudden overload occurs during the paint scraping process (such as a localized protrusion or foreign object obstructing the scraping process on the surface of the baffle 332), 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.

[0089] In one specific embodiment of this application, the paint blocking mechanism 300 may further include a support device 310 and a displacement driving device. At least one of the first support body 331 and the second support body 326 is driven by the displacement driving device to slide along the support device 310, and the sliding direction is the arrangement direction of the first support body 331 and the second support body 326. In this embodiment, by designing at least one of the first support body 331 and the second support body 326 as movable, the paint scraping part 325 and the shielding plate 332 can be controlled to move closer to each other and further away from each other as needed, so as to adjust the distance between them. This ensures that the paint scraping part 325 does not interfere with the movement of the shielding plate 332, while also allowing the paint scraping part 325 to approach the shielding plate 332 and scrape off the waste paint on the shielding plate 332.

[0090] In this embodiment, the first support 331 and the second support 326 can both slide on the support device 310. Two displacement driving devices can be used to drive the first support 331 and the second support 326 to reciprocate, respectively, and the directions of movement of the first support 331 and the second support 326 are parallel.

[0091] For ease of understanding, the displacement driving device that drives the first support 331 to move is defined as the first displacement driving device, and the displacement driving device that drives the second support 326 to move is defined as the second displacement driving device.

[0092] The first displacement driving device can drive the first support 331 to move the baffle 332, thereby adjusting the distance between the baffle 332 and the battery 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 332 and the battery 200 to be painted being too large or too small.

[0093] The second displacement drive device can drive the second support 326 to move the paint scraper 325, thereby adjusting the distance between the paint scraper 325 and the baffle 332. For example, before the paint scraper 325 rotates, the paint scraper 325 needs to move away from the baffle 332 to ensure that the paint scraper 325 does not interfere with the rotation of the baffle 332; when paint scraping is required, the paint scraper 325 needs to move closer to the baffle 332 so that the paint scraper 325 can fit against the baffle 332 and scrape off the waste paint on the baffle 332.

[0094] To ensure that the movement directions of the first support 331 and the second support 326 do not deviate, in this embodiment, the paint-blocking mechanism 300 may further include a guide rail assembly 340. The guide rail assembly 340 includes a guide rail and a slider that slides with the guide rail. The guide rail is disposed on the support device 310, and sliders are disposed on both the first support 331 and the second support 326. In this embodiment, the movement directions of the first support 331 and the second support 326 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 331 and the second support 326 move in the corresponding direction.

[0095] In one specific embodiment of this application, the paint-blocking mechanism 300 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 333, 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.

[0096] During the painting process, the paint booth is filled with a large amount of paint mist, which easily adheres to the surfaces of the first drive unit 333 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 service life of the equipment.
