Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0028] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The battery cell module stacking device provided by the present invention will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0030] See Figure 1-3 The battery weighing mechanism includes: a windshield mechanism 1, a weighing module 2, and a housing 3; the housing 3 has an opening 31; the weighing module 2 is placed inside the housing 3 for weighing the battery; the windshield mechanism 1 includes: a cover plate 11 and a drive mechanism 12; the surface of the cover plate 11 is located on the side of the opening 31 away from the drive mechanism 12; the drive mechanism 12 is connected to the cover plate 11, and the drive mechanism 12 is used to drive the cover plate 11 to open to expose at least part of the opening 31, or to drive the cover plate 11 to close to cover the opening 31.

[0031] In this embodiment, the battery weighing mechanism includes a windshield mechanism 1, a weighing module 2, and a housing 3. The cover plate 11 of the windshield mechanism 1 is positioned relative to the opening of the housing. The weighing module 2 is placed inside the housing 3. The drive mechanism 12 drives the cover plate 11, allowing it to open or close within a certain range. When the cover plate 11 is closed, the housing 3 and the cover plate 11 form a relatively enclosed environment. This reduces the influence of external airflow when weighing batteries. This is especially important for small objects like button batteries that require high weighing accuracy, as even minor environmental changes can affect the accuracy of the weighing results. The enclosed environment helps improve the accuracy and reliability of the weighing. The area of ​​the cover plate 11 is larger than the area of ​​the opening 31 to ensure that the cover plate 11 completely covers the opening 31 when closed.

[0032] When the cover 11 is opened for battery weighing, the drive mechanism 12 can control the degree to which the cover opens, allowing only a portion of the opening 31 to be exposed. This ensures smooth placement and removal of the battery while minimizing the impact of external airflow on the weighing environment inside the casing. Airflow may generate buoyancy and other forces, interfering with the accurate measurement of battery weight by the weighing module. Properly controlling the opening size effectively reduces this interference. The drive mechanism 12 can also drive the cover 11 to open, facilitating the user to place the battery into the casing 3 for weighing or to remove the battery after weighing. This eliminates the need to disassemble the entire device or perform complex operations, improving convenience and efficiency. Depending on the battery size, shape, and specific weighing requirements, the drive mechanism 12 can control the degree to which the cover 11 opens, revealing an appropriately sized opening 31. For example, for smaller batteries, only a smaller opening can be opened for placement and weighing, while for larger batteries, the opening can be enlarged to ensure operational flexibility and adaptability.

[0033] Optionally, see Figure 1-2 4. The cover plate 11 includes: a first cover plate 111 and a second cover plate 112; the first cover plate 111 and the second cover plate 112 are respectively connected to the drive mechanism 12, and the drive mechanism 12 is used to drive the first cover plate 111 and the second cover plate 112 to open or close in opposite directions.

[0034] In this embodiment, the cover plate 11 includes a first cover plate 111 and a second cover plate 112. The areas of the first cover plate 111 and the second cover plate 112 are basically the same. The first cover plate 111 and the second cover plate 112 are respectively connected to the drive mechanism 12. The drive mechanism 12 drives the first cover plate 111 and the second cover plate 112 to open or close in opposite directions, so that the opening 31 is located in the middle of the housing 3. The process of putting the battery into the housing 3 and taking it out of the housing 3 is more convenient. Moreover, the battery is located in the middle part of the housing, making it easier for the robot arm to position it when grasping, and it is less likely to cause unnecessary collisions with the housing and other components.

[0035] During opening and closing, the drive mechanism applies forces to the first cover plate 111 and the second cover plate 112 respectively, making the overall force on the cover plate 11 more even. This design avoids uneven force caused by an excessively large single cover plate, reduces the risk of deformation due to long-term use, and improves the reliability and stability of the overall structure.

[0036] Optionally, see Figure 1-2, 4. On one side of the first cover plate 111 close to the second cover plate 112, a sealing strip 113 is provided. Alternatively, on one side of the second cover plate 112 close to the first cover plate 111, a sealing strip 113 is provided. The sealing strip 113 is bonded to the side of the cover plate 11 away from the opening 31. The plane where the sealing strip 113 is located is parallel to the plane where the cover plate 11 is located. The length of the sealing strip 113 along the direction perpendicular to the opening direction of the first cover plate 111 and the second cover plate 112 is the same as the length of the first cover plate 111 and the second cover plate 112 in this direction. When the first cover plate 111 and the second cover plate 112 are closed, the sealing strip 113 can cover the gap between the first cover plate 111 and the second cover plate 112, making the internal weighing environment more enclosed and further improving the weighing accuracy.

[0037] Optionally, refer to Figure 1-2 , 4, 5. The driving mechanism 12 includes: a first support component 121, a transmission component 122, and a driving component 123; the transmission component 122 is movably connected to the cover plate 11, and the first support component 121 is movably connected to the transmission component 122; the driving component 123 includes a driving body 1231 and a power output member 1232, and the driving body 1231 is used to drive the power output member 1232 to move; the driving body 1231 is fixedly connected to the first support component 121, and the power output member 1232 is connected to the transmission component 122; when the power output member 1232 moves, it drives the transmission component 122 to move, and the transmission component 122 drives the first cover plate 111 and the second cover plate 112 to open or close in opposite directions.

[0038] In the embodiment of the present application, the driving mechanism is arranged on both sides of the cover plate 11 along the direction perpendicular to the opening direction.

[0039] Among them, the first support component 121 is composed of two parallel horizontal sides and a vertical side. The vertical side is arranged in the middle of the two horizontal sides and fixedly connected to the two horizontal sides, forming a shape similar to the Chinese character "工". This can save materials and space while ensuring good support for the driving mechanism, reduce the weight of the first support component 121, and improve the stability of the entire battery weighing mechanism.

[0040] In addition, two "L"-shaped fixing members are provided at the end of the first support component 121 away from the cover plate. The two fixing members are respectively arranged on both sides of the vertical side, fixing the vertical side and a horizontal side away from the cover plate 11 together, further improving the stability of the driving mechanism 12 and the entire battery weighing mechanism.

[0041] The first support component 121 provides stable support for the windshield mechanism 1, improving the system's reliability and service life. The first support component 121 is movably connected to the transmission component 122, while the drive body 1231 is fixedly connected to the first support component 121. This structure provides stable support throughout the entire movement process. When the power output component 1232 drives the transmission component 122, the first support component 121 ensures the stability of the transmission component 122's movement trajectory, reducing swaying and deviation, and improving the mechanism's reliability and service life. The connection method between the components facilitates the uniform transmission of force. The driving force generated by the drive body 1231 is transmitted to the transmission component 122 through the power output component 1232, and then from the transmission component 122 to the first cover plate 111 and the second cover plate 112. In this process, the first support component 121 plays a role in dispersing and balancing the force, avoiding excessive local stress and making the entire mechanism more stable during opening and closing.

[0042] By driving the power output component 1232 through the drive body 1231, the transmission component 122 is moved, thereby precisely controlling the opening or closing of the first cover plate 111 and the second cover plate 112 in opposite directions. The connection between the transmission component 122 and the first cover plate 111 and the second cover plate 112 allows the two cover plates to move synchronously in opposite directions under the drive of the power output component 1232, ensuring the consistency of the opening and closing actions.

[0043] Optionally, see Figure 1-2 4, 5, The drive body 1231 includes a cylinder 12311, and the power output component 1232 includes a piston rod 12321; one end of the piston rod 12321 is inside the cylinder 12311, and the other end of the piston rod 12321 is connected to the transmission assembly 122; the direction of movement of the piston rod 12321 is different from the direction of movement of the first cover plate 111 and the second cover plate 112.

[0044] In this embodiment, one end of the piston rod 12321 is precisely fitted inside the cylinder 12311, forming a sliding fit between the piston and the inner wall of the cylinder. A high-performance seal is installed on the piston to ensure that gas inside the cylinder does not leak during the reciprocating motion of the piston rod. The other end of the piston rod 12321 extends out of the cylinder and is reliably connected to the transmission assembly, such as via a threaded connection or coupling, to ensure effective power transmission.

[0045] The cylinder 12311 has an air inlet and a corresponding control valve at the end furthest from the transmission assembly 122. The air inlet is connected to an external air source. When the control system issues a command, the control valve opens, and compressed gas quickly enters the cylinder from the air inlet. The gas entering the cylinder 12311 pushes the piston and the piston rod 12321 connected to it to move linearly, thereby converting the pressure energy of the gas into mechanical energy, providing power to the transmission assembly 122, driving the transmission assembly 122 to run, and then transmitting the power to the first cover plate 111 and the second cover plate 112.

[0046] Optionally, see Figure 1-2 4, 5, The first support component 121 includes a first slide rail 1211 arranged along a first direction X; the first direction X is the direction of movement of the power output component 1232; the transmission component 122 includes: a first slider component 1221, a connecting rod 1222 and a connecting component 1223; the first slider component 1221 is slidably connected to the first slide rail 1211; one end of the connecting rod 1222 is movably connected to the first slider component 1221, and the other end of the connecting rod 1222 is movably connected to the connecting component 1223; the connecting component 1223 is fixedly connected to the cover plate 11; the power output component 1232 is fixedly connected to the first slider component 1221; when the power output component 1232 moves, it drives the first slider component 1221 to move within the first slide rail 1211, the first slider component 1221 drives the connecting rod 1222 to move, and the connecting rod 1222 drives the connecting component 1223 to move, so that the cover plate 11 opens or closes.

[0047] In this embodiment, the power output component 1232 is fixedly connected to the first slider assembly 1221, and the first slider assembly 1221 is slidably connected to the first slide rail 1211. The extension direction of the first slide rail 1211 is the same as the direction of movement of the power output component 1232, which is the first direction X. This configuration provides a stable guiding effect for the movement of the first slider assembly 1221, ensuring that the movement of the power output component 1232 can be transmitted accurately and without error, avoiding deviation and shaking during the movement process, realizing precise control of the movement of the cover plate 11, and improving the stability and reliability of the equipment operation.

[0048] One end of the connecting rod 1222 is movably connected to the first slider assembly 1221, and the other end of the connecting rod 1222 is movably connected to the connecting assembly 1223. The two ends of the connecting rod 1222 are movably connected to the first slider assembly 1221 and the connecting assembly 1223 respectively, so that the transmission assembly 122 has a certain degree of flexibility during movement. The first slider assembly 1221 transmits the power of the power output component 1232 to the connecting assembly 1223 through the connecting rod 1222. Since the connecting assembly 1223 is fixedly connected to the cover plate 11, the connecting assembly 1223 can drive the cover plate to open or close, thus meeting the working requirements of the weighing mechanism.

[0049] Optionally, see Figure 1-2 4, 5, The first support component 121 is provided with a second slide rail 1212 at one end near the cover plate 11; the sliding direction of the second slide rail 1212 is along the second direction Y; the second direction Y is different from the first direction X; the connecting component 1223 includes: a connecting plate 12231 and a second slider component 12232; the second slider component 12232 is slidably connected to the second slide rail 1212; the connecting plate 12231 is fixedly connected to the second slider component 12232 and the cover plate 11 respectively; the connecting plate 12231 is also movably connected to the connecting rod 1222; under the drive of the connecting rod 1222, the connecting plate 12231 drives the second slider component 12232 to move in the second slide rail, and drives the cover plate 11 to open or close.

[0050] In this embodiment of the application, a second slide rail 1212 is provided at one end of the first support component 121 near the cover plate 11; the sliding direction of the second slide rail 1212 is along the second direction Y; the second direction Y is different from the first direction X; the two slide rails in different directions can realize multi-axis linkage control, thereby achieving higher positioning accuracy and motion control accuracy.

[0051] The second slider assembly 12232 is slidably connected to the second slide rail 1212; the extension direction of the second slide rail 1212 is the same as the opening or closing direction of the cover plate 11, which is the second direction Y, so that the transmission assembly can more easily drive the cover plate 11 to move.

[0052] The connecting plate 12231 and the cover plate 11 are fixedly connected. The connecting plate 12231 consists of a side plate and a fixing block. The fixing block and the side plate can be integrally formed or fixedly connected by bolts or adhesive. The fixing block is located on the side of the side plate near the housing 3 and is connected to the cover plate 11. Both the fixing block and the cover plate 11 are provided with through holes, and the fixing block and the cover plate 11 can be tightly fixed together by bolts or other fasteners. The side plate is generally L-shaped, with the length of the side closer to the cover plate 11 being greater than the length of the side farther from the cover plate 11. The length of the side plate closer to the cover plate 11 is the same as the length of the cover plate 11 in the second direction Y. This arrangement ensures the stability of the fixed connection between the connecting plate 12231 and the cover plate 11. Since the length of the side farther from the cover plate 11 is less than the length of the side closer to the cover plate 11, it can save some manufacturing materials, reduce the weight of the windshield mechanism 1, and facilitate cooperation with other structures.

[0053] The side plate has several through holes, which can be used to connect to the fixed block or to the second slider. At the same time, the side plate also has a connecting hole for movably connecting to one end of the connecting rod 1222. This connection does not affect the rotation of the connecting rod 1222 on the side of the connecting plate 12231, and can drive the movement of the cover plate 11 through the connecting plate 12231.

[0054] The connecting plate 12231 and the second slider assembly 12232 are fixedly connected. Therefore, under the drive of the connecting rod 1222, the connecting plate 12231 can drive the second slider assembly 12232 to move in the second slide rail, and at the same time drive the cover plate 11 to open or close.

[0055] In addition, since one end of the connecting rod 1222 is movably connected to the connecting plate 12231 and the other end is connected to the first slider assembly 1221, the range of movement of the first slider assembly 1221 and the connecting plate 12231 is also limited due to the limitation of the length of the connecting rod 1222 itself. Therefore, the connecting rod 1222 can also play a limiting role, further ensuring the stability of the movement of the top cover 11.

[0056] Optionally, see Figure 1-2 4, 5, The connecting plate 12231 includes a first connecting plate 122311 and a second connecting plate 122312; the connecting rod 1222 includes a first connecting rod 12221 and a second connecting rod 12222; the second slider assembly 12232 includes a first sub-slider 122321 and a second sub-slider 122322; the first connecting rod 12221 is movably connected to the first connecting plate 122311, and the first connecting plate 122311 is fixedly connected to the first sub-slider 122321 and the first cover plate 111 respectively; the second connecting rod 12222 is movably connected to the second connecting plate 122312, and the second connecting plate 122312 is fixedly connected to the second sub-slider 122322 and the second cover plate 112 respectively.

[0057] In this embodiment, the first connecting rod 12221 and the second connecting rod 12222 are movably connected to the first connecting plate 122311 and the second connecting plate 122312, respectively, so that the power generated by the power output component 1232 can be transmitted to the first sub-slider 122321, the second sub-slider 122322, the first cover plate 111, and the second cover plate 112. The swing of the first connecting rod 12221 and the second connecting rod 12222 can be converted into linear sliding of the first sub-slider 122321 and the second sub-slider 122322 on the second slide rail 1212, thereby driving the movement of the first cover plate 111 and the second cover plate 112.

[0058] Since the first connecting rod 12221 is movably connected to the first connecting plate 122311, and the second connecting rod 12222 is movably connected to the second connecting plate 122312, parameters such as the length and swing angle of the first connecting rod 12221 and the second connecting rod 12222 can be adjusted according to actual needs, thereby flexibly controlling the movement speed, stroke, and direction of the slider and the cover plate. In some equipment requiring different working modes, these parameters can be adjusted to adapt to different working requirements.

[0059] Optionally, see Figure 1-2 4, 5, The drive mechanism also includes: a second support member 124; the second support member 124 is provided with a sliding groove 1241 on the side facing the cover plate 11, and the end of the first support component 121 near the second support member 124 is slidably connected to the sliding groove 1241.

[0060] In this embodiment, the second support member 124 can be connected to other structures, facilitating the connection of the battery weighing mechanism with other structures.

[0061] The second support member 124 is provided with a groove 1241 on the side facing the cover plate 11. The first support component 121 has a protrusion at one end near the second support member 124 that is adapted to the groove 1241. The second support member 124 is slidably connected to the groove 1241 through the protrusion.

[0062] This configuration makes it easier to position and adjust the position of the windshield mechanism 1 during assembly. The first support component 121 can more accurately cover the opening 31 of the housing 3 by sliding on the slide groove 1241.

[0063] Furthermore, when the first support assembly 121 is subjected to external force, the sliding of the second support member 124 within the slide groove 1241 can absorb and buffer the impact force to a certain extent. During equipment maintenance, if the first support assembly 121 or the slide groove 1241 is damaged, it is easy to disassemble and replace them because they are relatively independent sliding connections. Workers can easily remove the damaged parts from the slide groove 1241 for repair or replacement without significantly affecting the overall structure of the equipment, thus shortening maintenance time and improving equipment availability.

[0064] Optionally, see Figure 1-2 It also includes: a first support platform assembly 4; the first support platform assembly 4 includes: a first support column 41 and a first base 42; one end of the first support column 41 is fixedly connected to the housing 3 and the other end is fixedly connected to the first base 42; the second support member 124 is fixedly connected to the first base 42.

[0065] In this embodiment, the first support column 41 connects the housing 3 and the first base 42, forming a stable support frame. The first support columns 41 are distributed at the four corners of the first base 42, and the second support members 124 are fixedly connected to the first base 42. The relative distance between the two second support members 124 is greater than the distance between the two oppositely arranged first support columns 41 in a direction perpendicular to the opening direction of the cover plate. Furthermore, the distance between the first support column 41 and the side of the first base 42 is slightly greater than the width of the second support member 124, so that the second support member 124 can be completely placed on the first base 42.

[0066] The first base 42 provides a reliable mounting foundation for the second support member 124 fixed thereon. This ensures that the second support member 124 will not shift or wobble during operation, guaranteeing that it can accurately perform its function of supporting or connecting other components.

[0067] The height of the first support column 41 and the shape and size of the first base 42 can be flexibly adjusted according to the actual situation.

[0068] Optionally, see Figure 1-2 It also includes: a second support platform assembly 5; the second support platform assembly 5 includes: a second support column 51, a second base 52 and a foot pad assembly 53; one end of the second support column 51 is fixedly connected to the first base 42 and the other end is fixedly connected to the second base 52; the foot pad assembly 53 is disposed at the bottom of the second base 52 and is used to adjust the height of the second base 52.

[0069] In this embodiment, the second support column 51 connects the first base 42 and the second base 52 to form a multi-level support structure. This effectively disperses the weight of the battery weighing mechanism and the external forces generated during operation, enhancing overall stability and preventing the battery weighing mechanism from tipping over due to unstable center of gravity or uneven force.

[0070] The foot pad assembly 53 is located at the four corners of the second base 52, which allows the weight of the battery weighing mechanism to be evenly distributed across the foot pads, avoiding excessive localized stress and ensuring balance and stability during placement. The foot pad assembly 53 includes the foot pad body, bolts, and adjusting screws. The foot pad body is circular and made of a material with a certain degree of elasticity and wear resistance, such as rubber or polyurethane. It provides good anti-slip performance, ensuring the equipment remains stable on the ground, while also serving as a shock absorber and cushioning agent.

[0071] The adjusting screw passes through the second base 52 and is fixed above the foot pad body, and is secured with bolts. Changing the position of the bolts on the adjusting screw changes the height of the second base 52. Furthermore, when the equipment is installed on an uneven ground, adjusting each foot pad assembly 53 individually or in combination can keep the second base 52 level, ensuring that the weighing mechanism 2 is in a horizontal state and preventing performance and working accuracy from being affected by tilt.

[0072] Optionally, see Figure 1-2 The housing 3 includes a side plate 33 and a quick-release plate 32; the quick-release plate 32 includes a fixing plate 321, a flip connecting plate 322, and a first magnetic element 323; one end of the flip connecting plate 322 is flipped and connected to the fixing plate 321; the first magnetic element 323 is provided on the flip connecting plate 322 near the cover plate 11; the second magnetic element 331 is provided on the side plate 33 near the quick-release plate 32 and the cover plate 11; when the flip connecting plate 322 is closed, the first magnetic element 323 and the second magnetic element 331 attract each other.

[0073] In this embodiment, one end of the flip-connecting plate 322 is flipped and connected to the fixed plate 321, which makes it convenient for operators to open or close the flip-connecting plate 322 as needed to perform maintenance and other work on the weighing mechanism 2 placed inside the housing 3.

[0074] A first magnetic element 323 is provided on the flip-up connecting plate 322 near the cover plate 11, and a second magnetic element 331 is provided on the side plate 33 near the quick-release plate 32 and the cover plate 11. When the flip-up connecting plate 322 is closed, the first magnetic element 323 and the second magnetic element 331 attract each other, enabling the flip-up connecting plate 322 to be accurately positioned in the closed position. Each time the flip-up connecting plate 322 is closed, the magnetic force guides it to the correct position, facilitating operation and improving the stability of the overall structure. Due to the attraction between the first magnetic element 323 and the second magnetic element 331, the operator does not need additional tools or complicated operations to fix the flip-up connecting plate 322 when closing it; the flip-up closing action can be completed with one hand, using magnetic force to fix it in place, improving the convenience and efficiency of operation.

[0075] Optionally, see Figure 3 The fixed plate 321 and the flip-connecting plate 322 are connected by a hinge. The hinge connection makes the flip-connecting plate 322 and the fixed plate 321 relatively compact with almost no gaps. This ensures convenient maintenance and other operations while preventing excessive gaps between the flip-connecting plate 322 and the fixed plate 321 from allowing air to enter the housing and affect the weighing results.

[0076] Optionally, see Figure 3 The flip-up connecting plate 322 is also equipped with a handle, making it easier to open and close the quick-release plate 32.

[0077] The handle further enhances the ease of opening or closing the flip-up connecting plate 322. Optionally, at least one pre-drilled hole 332 is provided on one of the opposite side plates 33 of the quick-release plate 32 to allow wires to pass through the side plate 33.

[0078] A reserved hole 332 is provided on the side plate 33, which allows the wires of the electronic scale to pass through the reserved hole 332 and exit the housing 3, ensuring the normal operation of the weighing mechanism.

[0079] In practical applications, the size of the reserved hole 332 can be adjusted as needed.

[0080] Optionally, the cover plate 11, side plate 33 and quick-release plate 32 are all transparent acrylic sheets.

[0081] The cover plate 11, side plate 33 and quick-release plate 32 are made of transparent acrylic sheet, which allows for real-time observation of the battery's status inside the weighing module.

[0082] Optionally, see Figure 7 The weighing module 2 includes: at least two electronic scales 21, at least two electronic scale fixtures 22, and an electronic scale mounting plate 23; the electronic scale fixtures 22 are disposed above the electronic scales 21; the electronic scales 21 are disposed above the electronic scale mounting plate 23; adjacent electronic scale fixtures 22 are arranged and installed in a complementary manner by embedding them in pairs.

[0083] The weighing module 2 is equipped with multiple electronic scales, which can weigh multiple batteries simultaneously, thus improving weighing efficiency. Meanwhile, adjacent electronic scale fixtures 22 are arranged in a complementary, interlocking manner, resulting in smaller gaps between them and effectively improving space utilization.

[0084] Optionally, the electronic scale mounting plate 23 is a marble slab.

[0085] Marble is hard and highly flat, which allows the scale sensors placed on the marble mounting plate to be evenly stressed. This ensures that the scale can accurately sense the weight of the object during measurement, reducing measurement errors caused by uneven mounting plate surfaces and thus improving the scale's measurement accuracy.
