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] The first aspect of this application provides a waste paint collection facility, comprising:

[0009] Support frame;

[0010] The first paint baffle plate is slidably fitted to the support frame along the first direction. The first paint baffle plate is provided with a battery clearance groove. Paint baffle portions are formed on both sides of the battery clearance groove. One end of the battery clearance groove has an insertion port for inserting the battery to be painted, so that during the painting process, the surface of the battery to be painted is located above the paint baffle portion.

[0011] The second paint baffle includes at least an upper paint baffle portion disposed on the upper side of the first paint baffle, the upper paint baffle portion being configured to be located downstream of the battery to be painted along the painting direction;

[0012] A first driving device is used to drive the first paint baffle to reciprocate along a first direction.

[0013] The waste paint collection mechanism provided in this application is arranged on the side of the battery to be painted, away from the painting equipment, so that when the painting equipment sprays paint onto the battery, some paint mist that is not sprayed onto the battery will be sprayed onto the waste paint collection mechanism, which collects some of the paint mist. When the battery to be painted is conveyed to the painting station by the conveying mechanism, the first driving device drives the first paint baffle to move towards the battery. The first paint baffle of the waste paint collection mechanism has a battery clearance groove, and the two sides of the battery clearance groove are paint blocking parts. As the first paint baffle moves, the battery to be painted gradually extends into the battery clearance groove through the insertion port, so that the paint-to-be-painted surface of the battery is above the paint blocking parts. At the same time, the upper paint blocking part is located downstream of the battery along the painting direction. When the painting equipment is painting, the lower and rear sides of the battery to be painted are respectively provided with paint blocking parts and upper paint blocking parts. Paint mist that is not sprayed onto the battery will be sprayed onto the paint blocking parts and upper paint blocking parts. Waste paint on the paint blocking section and the upper paint blocking section can be cleaned regularly. This allows for the centralized recycling and reuse of waste paint, and also cleans the surfaces of the paint blocking section and the upper paint blocking section, preparing for better collection of waste paint.

Detailed Implementation

[0023] This application discloses a waste paint collection mechanism for collecting insulating paint that has not been sprayed onto the surface to be sprayed.

[0024] 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.

[0025] like Figure 1 and Figure 2 As shown, this application discloses a waste paint collection mechanism 100 and a battery 200 to be painted (e.g., ...). Figure 4 The battery casing (as shown) has multiple surfaces that need to be coated with insulating varnish in a paint booth. Of the four sides of the square battery (the four sides being the four surfaces excluding the cover side and the bottom surface corresponding to the cover), two large surfaces (the two largest surfaces among the four sides) and two small surfaces (the two smallest surfaces among the four sides) also need to be coated with insulating varnish.

[0026] Taking the painting of a small surface of a battery casing as an example, multiple batteries 200 to be painted are transported by a conveying device to the space between the waste paint collection mechanism 100 and the painting equipment in the paint booth. The painting equipment sprays paint in the direction of the batteries 200 to be painted. Some of the paint mist that is not sprayed onto the batteries 200 is intercepted by the waste paint collection mechanism 100, which collects the insulating paint that was not sprayed onto the batteries 200 for easy recycling.

[0027] In this embodiment, the waste paint collection mechanism includes a support frame 110, a first paint baffle 120, a second paint baffle 130, and a first driving device 150. The first paint baffle 120 is slidably fitted onto the support frame 110 along a first direction. The first paint baffle 120 has a battery clearance groove 122, with paint-blocking elements 121 formed on both sides of the battery clearance groove 122. One end of the battery clearance groove 122 has an insertion port for inserting a battery 200 to be painted, so that during painting operations, the surface of the battery 200 to be painted is positioned above the paint-blocking element 121.

[0028] When the battery 200 to be painted is transported to the paint booth for painting, it corresponds precisely to the insertion port of the battery clearance slot 122. As the first paint baffle 120 moves along a first direction towards the battery 200 to be painted, it allows the battery 200 to enter the battery clearance slot 122 through the insertion port. This ensures that the paint baffles 121 on both sides of the battery clearance slot 122 are located on both sides of the battery 200 to be painted and below the surface to be painted, preventing obstruction of the surface. The first paint baffle 120 can also block the space below the sides of the battery 200 to prevent paint mist from contaminating the equipment below the sides of the battery 200, and can also intercept and collect waste paint in this area.

[0029] The second paint baffle 130 includes at least an upper paint baffle portion 131 disposed above the first paint baffle 120. The upper paint baffle portion 131 is configured to be located downstream of the battery 200 to be painted along the painting direction. Since the upper paint baffle portion 131 is located downstream of the battery 200 to be painted, when the painting equipment paints the battery 200 to be painted, the paint passes over the battery 200 and is sprayed onto the upper paint baffle portion 131. This allows the upper paint baffle portion 131 to intercept and collect the insulating paint that is not sprayed onto the battery 200 to be painted, facilitating recycling.

[0030] The first driving device 150 is used to drive the first paint baffle 120 to reciprocate along a first direction. The first driving device 150 can be any driving device capable of outputting linear displacement, such as a cylinder, hydraulic cylinder, or linear motor module. The first driving device 150 can drive the first paint baffle 120 to reciprocate along the first direction. Before the battery 200 to be painted is transported to the painting station in the paint booth on the carrier via the conveying equipment, the first driving device 150 drives the first paint baffle 120 to move away from the battery 200 to prevent interference between the first paint baffle 120 and the battery 200 during transportation. When the battery 200 to be painted is transported to the painting station, the first driving device 150 drives the first paint baffle 120 to move closer to the battery 200, so that the paint baffle 121 moves to both sides of the battery 200, and the battery 200 enters the battery clearance groove 122. Those skilled in the art will understand that the purpose of providing the battery clearance groove 122 on the first paint baffle 120 is to avoid the battery 200 to be painted, so as to ensure that the paint baffle 121 can be distributed on both sides of the battery 200 to be painted, so as to block the lower area on both sides of the battery 200 to be painted.

[0031] In summary, 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 during use, 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, and the waste paint collection mechanism 100 will collect some of the paint mist.

[0032] When the battery 200 to be painted is conveyed to the painting station by the conveying mechanism, the first driving device 150 drives the first paint baffle 120 to move toward the battery 200 to be painted. The first paint baffle 120 of the waste paint collection mechanism 100 is provided with a battery clearance groove 122, and paint blocking elements 121 are on both sides of the battery clearance groove 122. As the first paint baffle 120 moves, the battery 200 to be painted gradually extends into the battery clearance groove 122 through the insertion port, so that the surface of the battery 200 to be painted is above the paint blocking elements 121. At the same time, the upper paint blocking part 131 is located downstream of the battery 200 to be painted along the painting direction.

[0033] During painting, the battery 200 to be painted is equipped with a paint baffle 121 on its lower side and an upper paint baffle 131 on its rear side. Paint mist that is not sprayed onto the battery 200 will be sprayed onto the paint baffle 121 and the upper paint baffle 131. The waste paint on the paint baffle 121 and the upper paint baffle 131 can be cleaned periodically. This allows for the centralized recycling and reuse of waste paint, and also cleans the surfaces of the paint baffle 121 and the upper paint baffle 131 to prepare for better collection of waste paint.

[0034] Typically, multiple batteries 200 to be painted need to be arranged at the spray booth in a paint booth for simultaneous painting to improve painting efficiency. Based on this, in this embodiment, the first paint baffle 120 is provided with multiple battery clearance slots 122. Each battery clearance slot 122 has a paint baffle 121 formed on both sides, and a paint baffle 121 is located between two adjacent battery clearance slots 122. The number of battery clearance slots 122 can be designed by those skilled in the art based on the number of batteries 200 to be painted simultaneously at the spray booth, so that the first paint baffle 120 can avoid all the batteries 200 to be painted.

[0035] Since the batteries 200 to be painted, conveyed by the conveying mechanism, are arranged at equal intervals, in this embodiment, the battery clearance slots 122 are also arranged at equal intervals, meaning that the distance between any two adjacent battery clearance slots 122 is equal. In other words, the dimensions of each paint baffle 121 along the arrangement direction of the battery clearance slots 122 are equal.

[0036] The waste paint collection mechanism disclosed in this embodiment is particularly suitable for collecting waste paint when spraying the small surfaces of a battery (two of the smaller surfaces out of the four sides). The width of the battery clearance groove 122 (i.e., the dimension of the battery clearance groove 122 along the arrangement direction of each battery clearance groove 122) should be slightly larger than the thickness of the battery 200 to be painted (i.e., the distance between the two large surfaces of the battery 200 to be painted) to ensure that the battery 200 to be painted can smoothly enter the battery clearance groove 122. The above distance can be obtained through experiments. Under the premise of ensuring that the battery 200 to be painted can smoothly enter the battery clearance groove 122, the smaller the above distance, the better the interception effect of paint mist, and the less likely the paint mist will enter the gap between the paint baffle 121 and the battery 200 to be painted and enter below the paint baffle 121, thus contaminating the equipment below.

[0037] When the battery 200 to be painted is a prismatic battery, the battery clearance groove 122 includes a bottom wall arranged opposite to the insertion port and two side walls 1222 connected to the bottom wall 1221. The two side walls 1222 of the battery clearance groove 122 are respectively used to correspond to the two large surfaces of the battery 200 to be painted. The distance between the two side walls 1222 is the width of the battery clearance groove 122, and the distance between the two large surfaces of the battery 200 to be painted is the thickness of the battery 200 to be painted.

[0038] In this embodiment, each battery clearance slot 122 is arranged along the second direction, and the first direction is perpendicular to the second direction, that is, the arrangement direction of the battery clearance slots 122 is perpendicular to the moving direction of the first paint baffle 120. The painting direction is parallel to the first direction, and the painting equipment sprays insulating paint towards the direction of the battery 200 to be painted. The surface closest to the painting equipment is the surface of the battery 200 to be painted. However, in addition to adhering to the surface of the battery 200 to be painted, the paint mist will also be sprayed into the part between the batteries 200 to be painted. The part of the paint mist with a lower flow rate will fall on the paint baffle 121 between the batteries 200 to be painted and be intercepted and captured by the paint baffle 121; the part of the paint mist with a higher flow rate will pass over the battery 200 to be painted and be sprayed onto the upper paint baffle 131 and be intercepted and captured by the upper paint baffle 131.

[0039] Since the width of the battery clearance groove 122 is slightly larger than the thickness of the battery 200 to be painted, the movement accuracy of the first paint baffle 120 along the first direction is required to be high. If the movement direction of the first paint baffle 120 deviates, the first paint baffle 120 will move towards the battery 200 after the battery 200 to be painted is transported to the painting station. This will result in the battery clearance groove 122 not corresponding to the battery 200 to be painted, causing the end of the paint baffle 121 to collide with the battery 200 to be painted, and preventing the paint baffle 121 from moving to both sides of the battery 200 to be painted.

[0040] Therefore, it is necessary to improve the movement accuracy of the first paint baffle 120 along the first direction. For example... Figure 2 As shown, the waste paint collection mechanism 100 disclosed in this embodiment may further include a first guide rail assembly 160. The first guide rail assembly 160 includes a first guide rail and a first slider that slides with the first guide rail. The first guide rail is disposed on the support frame 110, and the first slider is fixed on the first paint baffle 120. The first guide rail extends along a first direction. The first guide rail assembly 160 can provide a precise guiding path for the first paint baffle 120. Through the mutual sliding engagement of the first guide rail and the first slider, it strictly restricts the first paint baffle 120 to move only along the extension direction of the first guide rail, reducing offset and swaying during movement. In addition, the first guide rail assembly 160 also has good load-bearing capacity and can provide stable support for the first paint baffle 120. During movement, it can distribute the weight of the first paint baffle 120, making the movement more stable.

[0041] Furthermore, there can be multiple first guide rail assemblies 160, symmetrically arranged on both sides of the first driving device 150, which can further improve the movement accuracy of the first baffle plate 120 along the first direction. For example, there can be two first guide rail assemblies 160, symmetrically arranged along the first driving device 150. Of course, there can also be four first guide rail assemblies 160, as long as the number of first guide rail assemblies 160 is even.

[0042] In one specific embodiment of this application, the support frame 110 includes a support base 112 and a sliding support frame 111 disposed on the support base 112. The sliding support frame 111 is provided with a support groove 1111, and the first paint baffle 120 slides in cooperation with the support groove 1111. The support groove 1111 can support and limit the first paint baffle 120 in the vertical direction, restricting the position of the first paint baffle 120 in the vertical direction and preventing the first paint baffle 120 from moving in the vertical direction, which would cause a change in the painting position of the battery 200 to be painted. In this embodiment, the first paint baffle 120 is simultaneously limited in the vertical direction by the first guide rail assembly 160 and the sliding support frame 111, which improves the stability of the first paint baffle 120 in the vertical direction.

[0043] In one specific embodiment of this application, the waste paint collection mechanism 100 may further include a second driving device. The upper paint blocking part 131 is disposed at the output end of the second driving device to drive the upper paint blocking part 131 to switch between the paint scraping position and the avoidance position. The movement mode of the second driving device driving the upper paint blocking part 131 is not limited; it may be rotation, linear movement, or spatial movement that includes both movement and rotation.

[0044] In this embodiment, the spatial position of the upper paint blocking part 131 can be changed by the movement of the upper paint blocking part 131, so that the upper paint blocking part 131 not only has the function of intercepting and capturing paint mist, but also has the function of scraping off waste paint on the first paint blocking plate 120.

[0045] When the upper paint blocking part 131 is in the paint scraping position, its lower edge is in contact with the first paint blocking plate 120. When the upper paint blocking part 131 is in the paint scraping position, since it is in contact with the first paint blocking plate 120, in addition to intercepting and capturing paint mist, when the first paint blocking plate 120 moves in the first direction, the relative movement between the upper paint blocking part 131 and the first paint blocking plate 120 can also scrape off the waste paint on the upper surface of the first paint blocking plate 120.

[0046] When the upper paint-blocking part 131 is in the avoidance position, there is a gap between the lower edge of the upper paint-blocking part 131 and the first paint-blocking plate 120. When the upper paint-blocking part 131 is in the avoidance position, when the upper paint-blocking part 131 moves in the first direction, there will be no interaction with the upper paint-blocking part 131, so there will be no effect of scraping off the waste paint on the upper surface of the first paint-blocking plate 120.

[0047] In practical use, the following methods can be adopted:

[0048] Before the battery 200 to be painted is conveyed to the painting station in the paint booth on the carrier via the conveying equipment, the first drive device 150 drives the first paint baffle 120 to move away from the battery 200 to prevent the first paint baffle 120 from interfering with the transportation process of the battery 200 to be painted.

[0049] When the battery 200 to be painted is transported to the painting station, the first drive device 150 drives the first paint baffle 120 to move toward the direction of the battery 200 to be painted, so that the paint baffle 121 moves to both sides of the battery 200 to be painted, and the battery 200 to be painted enters the battery clearance groove 122. At this time, the upper paint baffle 131 is in the paint scraping position.

[0050] The painting equipment sprays paint towards the battery 200 to be painted. The lower side and the rear side of the battery 200 to be painted are respectively provided with a paint baffle 121 and an upper paint baffle 131. The paint mist that is not sprayed onto the battery 200 to be painted will be sprayed onto the paint baffle 121 and the upper paint baffle 131.

[0051] Waste paint on the upper paint blocking part 131 can flow downward under the action of gravity and drip onto the paint blocking part 121. When the waste paint on the paint blocking part 121 needs to be cleaned, the upper paint blocking part 131 is first switched to the avoidance position, and then the paint blocking part 121 is driven to move away from the battery 200 to be painted. Then the upper paint blocking part 131 is switched to the paint scraping position, and finally the paint blocking part 121 is driven to move closer to the battery 200 to be painted. Under the action of the relative movement between the upper paint blocking part 131 and the first paint blocking plate 120, the waste paint on the upper surface of the first paint blocking plate 120 is scraped off.

[0052] In this embodiment, as the paint-blocking component 121 moves toward the battery 200 to be painted, paint scraping is achieved. Waste paint on the paint-blocking component 121 can be scraped off from the side of the upper paint-blocking part 131 away from the battery 200 to be painted, preventing contamination of the components on the side near the battery 200 to be painted, thus affecting the subsequent painting effect on the battery 200 to be painted.

[0053] Furthermore, the second driving device includes a first rotating shaft 170, with the upper paint-blocking part 131 fixed to the first rotating shaft 170. The first rotating shaft 170 is driven to cause the upper paint-blocking part 131 to reciprocate, switching between a paint-scraping position and a clearance position. The first rotating shaft 170 is the swing axis of the upper paint-blocking part 131, which rotates along the axis of the first rotating shaft 170. The first rotating shaft 170 is rotatably supported on a support frame 110. The first rotating shaft 170 can be driven to rotate by a drive motor, which can be connected to the first rotating shaft 170 via a reducer to reduce the swing speed of the upper paint-blocking part 131.

[0054] The axial direction of the first rotating shaft 170 is parallel to the plane containing the first paint baffle 120, such that when the first rotating shaft 170 drives the upper paint baffle 131 to swing, the distance between the lower edge of the upper paint baffle 131 and the first paint baffle 120 is equal at any position. Preferably, the axial direction of the first rotating shaft 170 can be perpendicular to the first direction. When the upper paint baffle 131 is in the paint scraping position, it can be configured to be perpendicular to the first paint baffle 120. The first paint baffle 120 can be designed to be parallel to the horizontal plane, so that the upper paint baffle 131 is arranged vertically when in the paint scraping position, which can intercept more waste paint within the limited area of ​​the upper paint baffle 131.

[0055] In one specific embodiment of this application, the second paint baffle 130 may further include a lower paint baffle portion 132 disposed below the first paint baffle 120. The lower paint baffle portion 132 is configured to be located downstream of the battery 200 to be painted along the painting direction. Since the lower paint baffle portion 132 is located downstream of the battery 200 to be painted, when the painting equipment paints the battery 200, some of the paint mist that passes over the battery 200 will be sprayed onto the upper paint baffle portion 131 if it is above the first paint baffle 120, and onto the lower paint baffle portion 132 if it is below the first paint baffle 120. This allows the lower paint baffle portion 132 to intercept and collect the paint mist below the first paint baffle 120, improving the recycling efficiency.

[0056] Furthermore, the waste paint collection mechanism 100 may also include a third drive device, with the lower paint blocking part 132 disposed at the output end of the third drive device to drive the lower paint blocking part 132 to switch between the paint scraping position and the avoidance position. The movement of the lower paint blocking part 132 driven by the third drive device is not limited; it can be rotation, linear movement, or spatial movement that includes both movement and rotation.

[0057] In this embodiment, the movement of the lower paint baffle 132 can change the spatial position of the lower paint baffle 132, thereby enabling the lower paint baffle 132 to not only intercept and capture paint mist, but also scrape off waste paint on the first paint baffle 120.

[0058] When the lower paint baffle 132 is in the paint scraping position, its lower edge is in contact with the first paint baffle 120. When the lower paint baffle 132 is in the paint scraping position, since it is in contact with the first paint baffle 120, in addition to intercepting and capturing paint mist, when the first paint baffle 120 moves in the first direction, the lower paint baffle 132 can also scrape off the waste paint on the lower surface of the first paint baffle 120 due to the relative movement between the lower paint baffle 132 and the first paint baffle 120.

[0059] When the lower paint baffle 132 is in the clearance position, there is a gap between the lower edge of the lower paint baffle 132 and the first paint baffle 120. When the lower paint baffle 132 is in the clearance position, it will not interact with the first paint baffle 120 when it moves in the first direction, so it will not scrape off the waste paint on the upper surface of the first paint baffle 120.

[0060] In practical use, the following methods can be adopted:

[0061] Before the battery 200 to be painted is conveyed to the painting station in the paint booth on the carrier via the conveying equipment, the first drive device 150 drives the first paint baffle 120 to move away from the battery 200 to prevent the first paint baffle 120 from interfering with the transportation process of the battery 200 to be painted.

[0062] When the battery 200 to be painted is transported to the painting station, the first drive device 150 drives the first paint baffle 120 to move toward the direction of the battery 200 to be painted, so that the paint baffle 121 moves to both sides of the battery 200 to be painted, and the battery 200 to be painted enters the battery clearance groove 122. At this time, the upper paint baffle 131 and the lower paint baffle 132 are both in the paint scraping position.

[0063] The painting equipment sprays paint towards the battery 200 to be painted. A paint baffle 121 is provided on the lower side of the battery 200 to be painted, and an upper paint baffle 131 and a lower paint baffle 132 are provided on the rear side. Paint mist that is not sprayed onto the battery 200 to be painted will be sprayed onto the paint baffle 121, the upper paint baffle 131 and the lower paint baffle 132.

[0064] Waste paint on the upper paint baffle 131 can flow downwards under the action of gravity and drip onto the paint baffle 121. The lower paint baffle 132 intercepts very little waste paint and can be manually cleaned periodically. When the waste paint on the paint baffle 121 needs to be cleaned, first switch the upper paint baffle 131 and the lower paint baffle 132 to the avoidance position, then drive the paint baffle 121 to move away from the battery 200 to be painted, then switch the upper paint baffle 131 and the lower paint baffle 132 to the scraping position, and finally drive the paint baffle 121 to move closer to the battery 200 to be painted. Under the action of the relative movement between the upper paint baffle 131 and the lower paint baffle 132 and the first paint baffle 120, the waste paint on the upper and lower surfaces of the first paint baffle 120 is scraped off.

[0065] In this embodiment, as the paint-blocking component 121 moves toward the battery 200 to be painted, paint scraping is achieved. Waste paint on the paint-blocking component 121 can be scraped off from the side away from the battery 200 by the upper paint-blocking part 131 and the lower paint-blocking part 132, preventing contamination of the components near the battery 200 and affecting the subsequent painting effect on the battery 200.

[0066] Furthermore, the third driving device includes a second rotating shaft 180, with the lower paint-blocking part 132 fixed to the second rotating shaft 180. The second rotating shaft 180 is driven to cause the lower paint-blocking part 132 to reciprocate, switching between a paint-scraping position and a clearance position. The second rotating shaft 180 is the swing axis of the lower paint-blocking part 132, which rotates along the axis of the second rotating shaft 180. The second rotating shaft 180 is rotatably supported on a support frame 110. The second rotating shaft 180 can be driven to rotate by a drive motor, which can be connected to the second rotating shaft 180 via a reducer to reduce the swing speed of the lower paint-blocking part 132.

[0067] The axial direction of the second rotating shaft 180 is parallel to the plane containing the first paint baffle 120. This ensures that when the second rotating shaft 180 drives the lower paint baffle 132 to swing, the distance between the lower edge of the lower paint baffle 132 and the first paint baffle 120 is equal at any position. Preferably, the axial direction of the second rotating shaft 180 can be perpendicular to the first direction, and the first rotating shaft 170 and the second rotating shaft 180 can also be arranged parallel to each other. When the lower paint baffle 132 is in the paint scraping position, it can be configured to be perpendicular to the first paint baffle 120. The first paint baffle 120 can be designed to be parallel to the horizontal plane, so that the lower paint baffle 132 is arranged vertically when in the paint scraping position, which can intercept more waste paint within the limited area of ​​the lower paint baffle 132.

[0068] The first rotating shaft 170 and the second rotating shaft 180 can be driven by different drive motors or by the same drive motor. When driven by the same drive motor, meshing gears can be provided at the same ends of the first rotating shaft 170 and the second rotating shaft 180. The gear mechanism enables the first rotating shaft 170 and the second rotating shaft 180 to be linked together, and the rotation directions are opposite. The drive motor only needs to be connected to one of the first rotating shaft 170 and the second rotating shaft 180 for transmission.

[0069] In a specific embodiment of this application, the upper paint blocking part 131 and the lower paint blocking part 132 located in the paint scraping position are coplanar, that is, the upper paint blocking part 131 and the lower paint blocking part 132 are disposed on the upper and lower sides of the same position of the first paint blocking plate 120, so that the scraping positions of the upper paint blocking part 131 and the lower paint blocking part 132 are the same.

[0070] In one specific embodiment of this application, the upper paint blocking part 131 includes an upper paint blocking part body and a first scraper strip detachably fixed to the upper paint blocking part body. The first scraper strip is used to adhere to the first paint blocking plate 120. In this embodiment, the upper paint blocking part 131 is divided into two parts: the upper paint blocking part body serves as the mounting base for the first scraper strip, and the first scraper strip is used to scrape off waste paint from the upper surface of the first paint blocking plate 120. After the first scraper strip is deformed or worn, only the first scraper strip can be replaced, reducing the cost of use. It should be noted that since the upper paint blocking part 131 is divided into two parts, the upper paint blocking part body and the first scraper strip, the materials of the two components can be designed according to requirements. For example, the upper paint blocking part body can be made of a material with high strength and rigidity, such as metal; while the first scraper strip can be made of a flexible and deformable material, such as rubber or plastic, to prevent wear on the upper surface of the first paint blocking plate 120.

[0071] Correspondingly, the lower paint blocking section 132 includes a lower paint blocking section body and a second scraper strip detachably fixed to the lower paint blocking section body. The second scraper strip is used to adhere to the first paint blocking plate 120. In this embodiment, the lower paint blocking section 132 is divided into two parts. The lower paint blocking section body serves as the mounting base for the second scraper strip, and the second scraper strip is used to scrape off waste paint from the lower surface of the first paint blocking plate 120. After the second scraper strip is deformed or worn, only the second scraper strip can be replaced, reducing usage costs. It should be noted that since the lower paint blocking section 132 is divided into two parts, the lower paint blocking section body and the second scraper strip, the materials of the two components can be designed according to requirements. For example, the lower paint blocking section body can be made of a material with high strength and rigidity, such as metal; while the second scraper strip can be made of a flexible and deformable material, such as rubber or plastic, to prevent wear on the lower surface of the first paint blocking plate 120.

[0072] In one specific embodiment of this application, the waste paint collection mechanism 100 may further include a first paint storage device 140. The first paint storage device 140 is disposed below the upper paint blocking part 131 and the lower paint blocking part 132 located at the paint scraping position, and is used to store the waste paint scraped off by the upper paint blocking part 131 and the lower paint blocking part 132. The first paint storage device 140 may be a tank structure with the opening facing upward, so that the waste paint scraped off by the upper paint blocking part 131 and the lower paint blocking part 132 can fall into the first paint storage device 140 and be collected by the first paint storage device 140.

[0073] The first paint storage device 140 can collect waste paint, preventing it from flowing directly into the environment, reducing damage to the surrounding 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.

[0074] Furthermore, if the waste paint scraped off by the upper and lower paint-blocking sections 131 and 132 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 140 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.

[0075] like Figure 3 and Figure 4 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.

[0076] The waste paint collection system disclosed in this application also includes 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, while some paint mist that does not reach the battery lands on the waste paint collection mechanism 100. 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.

[0077] 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 behind and to the sides of the battery to be painted 200; the paint blocking mechanism 300 can collect the portion of waste paint sprayed in front of the battery to be painted 200 that falls due to gravity. This configuration maximizes the collection of unused paint mist in the paint booth, reducing pollution to the surrounding environment and improving waste paint recycling efficiency.

[0078] 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, a fourth driving device 333, and a paint scraping assembly 320. The first support 331 serves as a support for the baffle plate 332 and the fourth driving device 333, and at least provides a mounting base for the baffle plate 332.

[0079] 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 fourth 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 fourth driving device 333 may include a drive motor. To reduce the rotational speed of the baffle plate 332, the fourth 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.

[0080] 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.

[0081] 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, such as scraping and cleaning waste paint from 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.

[0082] The paint scraping assembly 320 includes a second support 326, a paint scraping part 325, a second driving device, and a second paint storage device 3251. The paint scraping part 325 is slidably fitted onto the second support 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 does not change due to sliding.

[0083] 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 fifth drive 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 fifth drive 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.

[0084] 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.

[0085] The second paint storage device 3251 is disposed on the lower side of the paint scraper trough 3252 and is used to store the waste paint scraped off by the paint scraper trough 3252. The second paint storage device 3251 can be a tank structure with the opening facing upward. The waste paint scraped off by the paint scraper 325 can fall into the second paint storage device 3251 and be collected by the second paint storage device 3251.

[0086] 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.

[0087] 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.

[0088] It should be noted that during the painting process, the masking plate 332 and the first paint baffle 120 can correspond to the same position of the battery 200 to be painted, so that the part of the battery 200 to be painted below the masking plate 332 and the first paint baffle 120 forms a blank area.

[0089] When the paint blocking mechanism 300 is used to block the blank area, the fourth drive device 333 can drive the shielding plate 332 to the blocking position. At this time, the shielding 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 shielding plate 332 and cannot be sprayed to the blocked position, thus forming a blank area. After the painting is completed, the shielding 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 shielding plate 332 can also block the carrier, preventing paint mist from being sprayed onto the carrier and avoiding the problem of waste paint on the carrier affecting the support accuracy.

[0090] 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.

[0091] 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.

[0092] 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).

[0093] 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.

[0094] 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.

[0095] 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.

[0096] Furthermore, in this embodiment, the fifth 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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 second guide rail assembly 340. The second 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.

[0106] 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 fourth driving device 333, and the second protective cover is disposed on the outside of the fifth 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 fourth driving device 333 and the fifth driving device to achieve shielding and protection for them. It should be noted that a third protective cover may also be provided on the outside of the first driving device 150.

[0107] During the painting process, the paint booth is filled with a large amount of paint mist, which easily adheres to the surfaces of the fourth drive unit 333 and the fifth 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 fourth drive unit 333 and the fifth drive unit, affecting their operation. They also prevent the chemical components in the paint mist from corroding and damaging the fourth drive unit 333 and the fifth drive unit, extending the equipment's service life.

Generally, the terms "comprising" and "including" only indicate the inclusion of expressly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.
