[0005] The adjustment mechanism of the embodiment of the present application cooperates with the slider and the guide rail to make the sliding part slide relative to the base, the base is fixedly connected to the first device, and the sliding part is fixedly connected to the second device, so that the first device and the second device can move away from or close to each other relative to each other along the extension direction of the guide rail, and then the spacing between the first device and the second device can be adjusted quickly and conveniently through the adjustment mechanism, and the spacing between the two groups of devices can be adjusted by sliding, which is convenient for visually measuring the moving distance and improving the accuracy of the adjustment. The adjustment mechanism of the embodiment of the present application is applied to the gluing process of the pole ear in the battery production process, which is convenient for adjusting the distance between the two groups of gluing equipment when switching products, reducing the scratches of the products during the production process, and improving the accuracy of the insulating film coating position. In addition, the spacing debugging operation is convenient, which can shorten the debugging time, which is conducive to improving production capacity and saving manpower.

[0006] In some embodiments, the adjustment mechanism includes a locking structure connected to the sliding member, and the locking structure is used to lock the sliding member on the base to limit the sliding of the sliding member relative to the base.

[0007] In this way, the sliding member is restricted from sliding relative to the base by the locking structure, thereby locking the relative positions of the first device and the second device when the distance between the first device and the second device is accurately adjusted.

[0012] In some embodiments, every two locking holes adjacent to each other along the sliding direction of the sliding member are connected.

[0013] In this way, by connecting adjacent locking holes, the locking holes are arranged more densely along the sliding direction of the sliding member, thereby improving the adjustment accuracy of the adjustment mechanism.

[0015] In this way, by providing locking holes on a plurality of locking plates, the locking holes can be arranged more densely within a limited space on the base.

[0016] In some embodiments, in two adjacent locking plates, the locking holes on one locking plate and the locking holes on the other locking plate are staggered along the sliding direction of the sliding member with a smaller hole diameter than the locking holes.

[0020] In some embodiments, the indicating structure includes a scale mark and a pointer, the scale mark is arranged on the base, and the pointer is arranged on the sliding member.

[0021] In this way, by setting a scale mark on the base and a pointer on the sliding member, the scale pointed to by the pointer on the scale mark can indicate the distance the sliding member slides relative to the base, thereby indicating the distance the sliding member drives the second device to move relative to the first device through the indicating structure.

[0022] In some embodiments, the sliding member is provided with a window, the pointer is arranged at the window, and part of the scale mark is exposed through the window.

[0023] In this way, the scale mark and the pointer are exposed through the window, which facilitates visual estimation of the sliding distance during the sliding process of the sliding member.

[0024] In some embodiments, the adjustment mechanism includes a guide assembly, the guide assembly includes a guide rail and a slider, the guide rail is installed on the base, the slider is slidably disposed on the guide rail, and the sliding member is fixedly connected to the slider.

[0025] In this way, the guide rail cooperates with the slider so that the slider can slide smoothly along a preset direction, so that the adjustment mechanism can adjust the distance between the first device and the second device in the preset direction and improve the stability of the adjustment mechanism.

[0026] In some embodiments, the adjustment mechanism includes a stopper, and the stopper is arranged at an end of the guide rail in the length direction.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0049] At present, judging from the development of the market situation, the application of batteries is becoming more and more extensive. Batteries can not only be used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as mobile communication equipment, smart wearables, aerospace and other fields. With the diversification of usage scenarios and the growth of market demand, the requirements for battery quality and production efficiency are also increasing.

[0050] A battery can be composed of one or more battery cells. A battery cell generally includes a housing, an electrode assembly and a pole. The electrode assembly includes a main body that generates electrical energy and a pole ear that is electrically connected to the main body. The pole is usually set on the housing and connected to the main body through the pole ear to conduct electrical energy. Battery cells can be used in electrical devices that use batteries as power sources or various energy storage systems that use batteries as energy storage elements.

[0051] The electrical device may be, but is not limited to, a vehicle, a mobile phone, a portable device, a laptop computer, a ship, a spacecraft, an electric toy, an electric tool, and the like. Among them, the spacecraft may be an airplane, a rocket, a space shuttle, a spacecraft, and the like, the electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, an electric airplane toy, and the like, and the electric tool may include a metal cutting electric tool, a grinding electric tool, an assembly electric tool, and an electric tool for railways, such as an electric drill, an electric grinder, an electric wrench, an electric screwdriver, an electric hammer, an impact drill, a concrete vibrator, and an electric planer, and the like. The embodiments of the present application do not impose any special restrictions on the above-mentioned electrical devices.

[0052] The battery can be a power battery used to provide driving power for new energy vehicles, electric bicycles, electric trains and other means of transportation. The battery can also be an energy storage battery used as a storage battery for renewable energy sources such as solar power generation, wind power generation, and hydropower generation.

[0053] In the production process of power batteries, ultrasonic welding of the pole ear is an important process. Ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the two surfaces of the objects rub against each other to form a fusion between the molecular layers. After a set of electrode assemblies are welded, a special insulating film is usually pasted on the front / back of the pole ear weld mark area to protect the pole ear from cracking, prevent weld mark contamination, and insulate the pole ear from the battery cell diaphragm.

[0054] In the process of applying the insulating film, the welded electrode assembly is placed by the glue sticking equipment, and the electrode assembly is moved to the correct position under the glue sticking assembly for glue sticking. Therefore, the distance between each two sets of glue sticking equipment has an important influence on the accuracy of the glue sticking position.

[0055] However, since the existing glue sticking assembly lacks a servo motor in the Y-axis direction, it is difficult to adjust the glue sticking position of the glue sticking assembly in the Y-axis direction. When changing the product being produced, the glue sticking equipment can only be moved to make the tab position match the glue sticking assembly.

[0056] In order to ensure that the glue sticking equipment can adapt to products of different specifications, a fixed screw can be used to adjust the distance between the two sets of glue sticking equipment. However, the fixed screw is slow to debug, and the moving distance is difficult to visually quantify. It often requires repeated debugging, and the debugging results depend on the subjective judgment of the debugging workers, which is prone to linkage errors, and the probability of product collision and scratching is high, affecting product quality and subsequent processes. For example, if the spacing of the glue sticking equipment is not accurately debugged, the insulating film coating position is offset, resulting in the insulating film covering the injection nozzle and affecting the injection of electrolyte.

[0057] Against the background of increasingly stringent requirements for battery quality and production efficiency, the adjustment mechanism of the implementation mode of the present application is arranged in the interval between the two groups of glue sticking equipment in the Y-axis direction, which can quickly and easily adjust the distance between the two groups of glue sticking equipment along the Y-axis direction, and the adjustment accuracy is relatively high. The debugging process can accurately grasp the debugging distance through the scale marking, thereby ensuring the accuracy of the tab glue sticking position, improving the quality rate of the glue sticking process, and saving equipment debugging time.

[0058] Please refer to Figure 1 For the convenience of explanation, the electric power consumption device of one embodiment of the present application is described as a vehicle 1000.

The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 200 is provided inside the vehicle 1000, and the battery 200 may be provided at the bottom, head or tail of the vehicle 1000. The battery 200 may be used to power the vehicle 1000, for example, the battery 200 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 400 and a motor 300, and the controller 400 is used to control the battery 200 to power the motor 300, for example, for starting, navigating and driving the vehicle 1000.

[0059] In some embodiments of the present application, the battery 200 can not only serve as the operating power source of the vehicle 1000, but also serve as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0060] Please refer to Figure 2 , Figure 2 An exploded view of a battery 200 provided for some embodiments of the present application. The battery 200 includes a box 210 and a battery cell 100, and the battery cell 100 is contained in the box 210. Among them, the box 210 is used to provide a storage space for the battery cell 100, and the box 210 can adopt a variety of structures. In some embodiments, the box 210 may include a first part 211 and a second part 212, and the first part 211 and the second part 212 cover each other, and the first part 211 and the second part 212 jointly define a storage space for accommodating the battery cell 100. The second part 212 may be a hollow structure with one end open, and the first part 211 may be a plate-like structure, and the first part 211 covers the open side of the second part 212, so that the first part 211 and the second part 212 jointly define a storage space; the first part 211 and the second part 212 may also be hollow structures with one side open, and the open side of the first part 211 covers the open side of the second part 212. Of course, the box body 210 formed by the first part 211 and the second part 212 can be in various shapes, such as a cylinder, a cuboid, etc.

[0061] In the battery 200, there may be multiple battery cells 100, and the multiple battery cells 100 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 100 are both connected in series and in parallel. The multiple battery cells 100 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 100 is accommodated in the box 210; of course, the battery 200 may also be a battery module formed by connecting multiple battery cells 100 in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in the box 210. The battery 200 may also include other structures, for example, the battery 200 may also include a busbar component for realizing electrical connection between the multiple battery cells 100.

[0062] Each battery cell 100 may be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 100 may be cylindrical, flat, rectangular, or in other shapes.

[0063] See also Figure 3 , Figure 3 This is a schematic diagram of the exploded structure of a battery cell provided in some embodiments of the present application. Figure 3 The battery cell 100 includes a shell 10 and an electrode assembly 20. The shell 10 is a component for accommodating the electrode assembly 20. The shell 10 may be a hollow structure with an opening formed at one end, and the first wall 110 may cover the opening. The shell 10 may be in various shapes, such as a cylinder, a flat body, a rectangular parallelepiped, etc. The shape of the shell 10 may be consistent with the shape of the battery cell 100. The material of the shell 10 may be a hard metal or alloy, such as copper, iron, aluminum, steel, aluminum alloy, etc.

[0064] The battery cell 100 has a positive electrode and a negative electrode, and the electrode assembly 20 is a component in which an electrochemical reaction occurs in the battery cell 100 to form the positive and negative electrodes of the battery cell 100. The electrode assembly 20 is accommodated in the hollow space inside the shell 10. The electrode assembly 20 may include a main body 21 and a pole ear 22, wherein the main body 21 may be a winding structure formed by winding a positive electrode sheet, a separator and a negative electrode sheet, or a stacked structure formed by stacking a positive electrode sheet, a separator and a negative electrode sheet. The pole sheet is usually made of lithium ions and metal materials such as cobalt, nickel, manganese, and aluminum. The pole sheet is used to embed or release ions in the electrolyte to generate electrical energy.

[0065] The tab 22 is a conductor that leads the positive and negative electrodes from the main body 21 and is used to transmit electrical energy. The tab 22 can also serve as a contact point when the battery cell 100 is charged and discharged. The tab 22 can be a metal conductor that is welded to the pole piece separately. The tab 22 can be made of the same metal material as the pole piece. For example, the negative pole tab 22 is connected to the positive pole piece, and the negative pole tab 22 uses nickel (Ni) material.

[0066] The housing 10 can cover the electrode assembly 20, and the tabs 22 are led out from the positive and negative electrodes of the body 21 and connected to the poles. For example, the tabs 22 can be fixedly connected to the sides of the poles by welding. The pole pieces and the circuit outside the battery cell 100 can be connected through the tabs 22 and the poles. The positive tab 22 and the negative tab 22 can be separately arranged at opposite ends of the same side wall of the housing 10 to prevent the electrode assembly 20 from short-circuiting.

[0067] According to some embodiments of the present application, referring to Figure 4 , Figure 4 This is a schematic diagram of the structure of the production equipment provided by some embodiments of the present application, and please refer to Figures 4 to 6 The adjustment mechanism 40 of the embodiment of the present application is arranged between the first device 2100 and the second device 2200 which are opposite and spaced apart, and the adjustment mechanism 40 includes a base 50 and a sliding member 60. The base 50 is fixedly connected to the first device 2100, and the sliding member 60 is slidably arranged on the base 50, and the sliding member 60 is fixedly connected to the second device 2200.

[0068] Specifically, the first device 2100 and the second device 2200 may be devices for placing the battery cell 100 and cooperating with a glue sticking assembly (not shown) to stick an insulating film to the tab 22. Figure 5 As shown, the Y-axis direction in the figure is the direction in which the first device 2100 and the second device 2200 are relative and spaced, and the X-axis direction in the figure is perpendicular to the above-mentioned Y-axis direction. The plane where the X-axis and the Y-axis are located is a horizontal plane, and the first device 2100 and the second device 2200 can form a placement platform roughly along the horizontal plane. The Z-axis direction in the figure is perpendicular to the horizontal plane, and the Z-axis direction is also the vertical direction. During the gluing process, the battery cell 100 can be placed flat on the placement platform, and the placement platform of the same device can accommodate one, two or more battery cells 100. Two or more battery cells 100 can be placed on the first device 2100 or the second device 2200 with one side provided with an end cover opposite to the other.

[0069] The adjustment mechanism 40 is fixedly connected to the first device 2100 through the base 50, and the sliding member 60 is fixedly connected to the second device 2200, so that when the sliding member 60 slides relative to the base 50, it drives the second device 2200 to move relative to the first device 2100 along the Y-axis direction.

[0070] The base 50 can be horizontally arranged between the first device 2100 and the second device 2200, and the sliding member 60 can be arranged above the base 50. The sliding member 60 can slide in the horizontal plane where the base 50 is located, which helps the first device 2100 and the second device 2200 to remain in the same horizontal plane during the debugging process. The present application does not limit the relative position of the sliding member 60 and the base 50, and the sliding member 60 can also be arranged at the front side, rear side, left side, right side or bottom of the base 50. The base 50 may include a first end 51 fixed to the first device 2100 and a second end 52 overlapped with the second device 2200, and a connecting portion 53 connecting the first end 51 and the second end 52. The connecting portion 53 may be in the shape of a strip, and the number of the connecting portions 53 may be multiple, and the multiple connecting portions 53 may be arranged in parallel along the Y-axis direction. The base 50 may be fixedly connected to the first device 2100 by at least one of welding, bonding, threaded connection, and fixing member connection. Exemplarily, the first end 51 and the first device 2100 are connected by a fixing member, and the first end 51 may be formed with a mounting hole 54. The fixing member may be a bolt and the first end 51 and the first device 2100 are tightened through the mounting hole 54. The first end 51 may extend along the X-axis direction to increase the contact area between the adjustment mechanism 40 and the first device 2100 and improve the connection strength.

[0071] A plurality of connecting parts 53 may be arranged at intervals, and the sliding member 60 may partially extend into the intervals between the connecting parts 53 and contact the second device 2200, so that the connecting part 53 may limit and stabilize the sliding process of the sliding member 60. The sliding member 60 may extend in the X-axis direction above the base 50 in the shape of a long strip, and the sliding member 60 may be at an angle of nearly 90° with the connecting part 53. Such a design is convenient for production and assembly, and is also conducive to limiting the sliding direction of the sliding member 60. The sliding member 60 and the second device 2200 may be connected together by at least one of welding, snap connection, inlaying, and connection with a fixing member. Exemplarily, the part of the sliding member 60 that extends between the connecting parts 53 and contacts the second device 2200 is the clamping part 61, and the sliding member 60 may be fixedly connected to the second device 2200 at the clamping part 61 by fixing members such as screws or bolts.

[0072] In some extended embodiments, the first device 2100 and the second device 2200 may be various types of devices, equipment, and products that require adjustment of the spacing distance in a specific direction.

[0073] The adjustment mechanism 40 of the embodiment of the present application cooperates with the slider 92 and the guide rail 91 to make the slider 60 slide relative to the base 50, the base 50 is fixedly connected to the first device 2100, and the slider 60 is fixedly connected to the second device 2200, so that the first device 2100 and the second device 2200 can move away from or close to each other along the extension direction of the guide rail 91. Then, the adjustment mechanism 40 can quickly and easily adjust the spacing between the first device 2100 and the second device 2200, and at the same time, the spacing between the two groups of devices can be adjusted by sliding, which is convenient for visually measuring the moving distance and improving the accuracy of the adjustment. The adjustment mechanism 40 of the embodiment of the present application is applied to the gluing process of the tab 22 in the battery production process, which is convenient for adjusting the distance between the two groups of gluing equipment when switching products, reducing the scratches of the products during the production process, and improving the accuracy of the insulating film coating position. In addition, the spacing debugging operation is convenient, which can shorten the debugging time, which is conducive to improving production capacity and saving manpower.

[0074] See also Figure 5 In some embodiments, the adjustment mechanism 40 includes a locking structure 70 connected to the sliding member 60 , and the locking structure 70 is used to lock the sliding member 60 on the base 50 to limit the sliding of the sliding member 60 relative to the base 50 .

[0075] Specifically, the locking structure 70 can be provided on the connecting portion 53, and the locking structure 70 can fix the base 50 and the sliding member 60 when the first device 2100 and the second device 2200 are adjusted in place, so that the sliding member 60 is fixed relative to the base 50. The locking structure 70 can use one or more of the following elements: indexing pins, positioning pins, supporting pins and supporting plates, buckles, and limiting blocks to achieve the limiting function of the sliding member 60.

[0076] In this way, the locking structure 70 limits the sliding of the sliding member 60 relative to the base 50, thereby locking the relative positions of the first device 2100 and the second device 2200 when the distance between the first device 2100 and the second device 2200 is accurately adjusted.

[0077] See also Figure 5 In some embodiments, the locking structure 70 includes a locking column 71 and a locking plate 72. The locking plate 72 is fixed on the base 50 and is provided with a plurality of locking holes 720. The plurality of locking holes 720 are arranged along the sliding direction of the sliding member 60. The locking column 71 is movably provided on the sliding member 60. When the locking column 71 is inserted into the locking hole 720, the sliding member 60 is locked on the base 50.

[0078] Specifically, the locking post 71 can be inserted into the sliding member 60, and can slide along the Y-axis direction with the sliding member 60 relative to the base 50. The locking post 71 can partially move up and down relative to the sliding member 60, and the bottom of the locking post 71 can be inserted into the locking hole 720 when the locking post 71 moves downward relative to the sliding member 60, and disengage from the locking hole 720 when the locking post 71 moves upward relative to the sliding member 60. The locking plate 72 can be arranged on the connecting portion 53, and the locking holes 720 are arranged along the sliding direction of the sliding member 60, that is, the Y-axis direction. The present application does not limit the locking plate 72 and the base 50 to be integrally formed or separately formed. The locking plate 72 and the base 50 can be made of the same material or different materials.

[0079] In some embodiments, the base 50 can be made of a light metal material, such as aluminum and aluminum alloy. The locking plate 72 is made of a material with greater strength than the base 50, such as carbon structural steel, alloy steel, etc. During the use of the adjustment mechanism 40, the locking column 71 needs to be repeatedly inserted into and out of the locking hole 720, and the sliding member 60 and the second device 2200 are fixed relative to the second device 2200 by the locking column 71 and the locking plate 72, and the locking plate 72 is subjected to greater stress. Using a stronger steel material to make the locking plate 72 is conducive to increasing the durability of the locking structure 70, maintaining the accuracy of the distance adjustment and the firmness of the locking. At the same time, the base 50 can be made of a relatively light material to reduce the overall weight of the adjustment mechanism 40.

[0080] In a specific embodiment, the base 50 is made of AL6061 aluminum alloy material, and the locking plate 72 is made of SUS304 stainless steel. The locking plate 72 can be fixed on the base 50 by using an inlay process.

[0081] In this way, the locking plate 72 cooperates with the locking column 71 to control the sliding or locking of the sliding member 60 relative to the base 50, thereby controlling the relative movement of the first device 2100 and the second device 2200. In addition, the locking plate 72 and the base 50 are separately arranged to take into account the strength of the locking structure 70 and the overall lightweight of the adjustment mechanism 40.

[0082] See also Figure 5 In some embodiments, the locking column 71 includes a plunger 711 and a knob 712 connected to the plunger 711. The plunger 711 is movably arranged relative to the sliding member 60. The plunger 711 is inserted into the locking hole 720 or separated from the locking hole 720 when the knob 712 rotates.

[0083] Specifically, the plunger 711 can be inserted into the sliding member 60 in a vertical direction, the knob 712 can be located above the plunger 711, the plunger 711 can be located at the bottom of the locking column 71, and the plunger 711 can move up and down when the knob 712 rotates. The knob 712 rotates in a first direction or a second direction, and the first direction is opposite to the second direction. When the knob 712 rotates in the first direction, the plunger 711 moves downward and the plunger 711 is inserted into the locking hole 720. When the knob 712 moves in the second direction, the plunger 711 moves upward and separates from the locking hole 720.

[0084] When the rotation angle of the knob 712 along the first direction is W, the locking structure 70 locks the sliding member 60 on the base 50. When the rotation angle of the knob 712 along the second direction is W, the locking structure 70 can slide synchronously with the sliding member 60. The rotation angle W can be any angle greater than 0°, such as 85°, 90°, 165°, 180°, 200°, etc.

[0085] Exemplarily, the rotation angle W is 180°. The manipulation knob 712 is rotated 180° in the second direction, the knob 712 can move upward while rotating, the plunger 711 is separated from the locking hole 720, and the slider 92 can slide relative to the base 50. When the slider 92 slides to the corresponding locking hole 720 position, the manipulation knob 712 is rotated 180° in the first direction, the knob 712 can move downward while rotating, the plunger 711 is inserted into the locking hole 720, and the slider 60 is locked on the base 50. In this embodiment, the locking column 71 can adopt an indexing pin, and the indexing pin can be a standard part to reduce the manufacturing cost.

[0086] In this way, the plunger 711 is inserted into the locking hole 720 by rotating the knob 712 so that the sliding member 60 is locked on the base 50, or the plunger 711 is separated from the locking hole 720 by rotating the knob 712 so that the sliding member 60 can slide relative to the base 50, thereby quickly adjusting the relative position of the first device 2100 and the second device 2200, and the debugging operation is convenient.

[0087] See also Figure 5 In some embodiments, every two adjacent locking holes 720 along the sliding direction of the sliding member 60 are connected.

[0088] Specifically, the locking hole 720 can be circular, oval, square, diamond, rectangular, polygonal or other irregular shapes with curved and straight edges, and each locking hole 720 has the same shape and size. The cross-sectional shape and size of the bottom of the plunger 711 match the shape and size of the locking hole 720, so that when the plunger 711 is inserted into the locking hole 720, the locking structure 70 can fasten the sliding member 60 to the locking plate 72. Exemplarily, the shape of the locking hole 720 is circular for illustration in this application.

[0089] Along the sliding direction of the sliding member 60, that is, the Y-axis direction, the distance between the centers of each two adjacent locking holes 720 is less than or equal to the diameter of the locking holes 720, and the contours of each two adjacent locking holes 720 intersect or are tangent to each other in the Y-axis direction, and each two adjacent locking holes 720 are connected at the intersection or tangent point. Each two adjacent locking holes 720 are approximately gourd-shaped as a whole.

[0090] In this way, by connecting adjacent locking holes 720 , the locking holes 720 are arranged more densely along the sliding direction of the sliding member 60 , thereby improving the adjustment accuracy of the adjustment mechanism 40 .

[0091] See also Figure 5 In some embodiments, there are multiple locking plates 72 , and the multiple locking plates 72 are arranged at intervals, and each locking plate 72 is provided with a locking hole 720 .

[0092] Specifically, the number of the locking plates 72 may be two, three, four or more. The plurality of locking plates 72 may be arranged at intervals along the X-axis direction. Exemplarily, the number of the locking plates 72 is two, and the two locking plates 72 are arranged at intervals along the X-axis direction on the base 50. The two locking plates 72 may be both disposed on the connecting portion 53 between the two clamping portions 61 to concentrate stress.

[0093] In this way, by providing locking holes 720 on a plurality of locking plates 72 , the locking holes 720 can be arranged more densely within a limited space on the base 50 .

[0094] See also Figure 6 In some embodiments, in two adjacent locking plates 72 , the locking holes 720 on one locking plate 72 and the locking holes 720 on the other locking plate 72 are staggered along the sliding direction of the sliding member 60 with a hole diameter smaller than the locking holes 720 .

[0095] Specifically, the two adjacent locking plates 72 are the first locking plate 721 and the second locking plate 722, and the geometric center of the locking hole 720 on the first locking plate 721 closest to the first device 2100 and the geometric center of the locking hole 720 on the second locking plate 722 closest to the first device 2100 are separated by a certain distance d in the Y-axis direction. The locking holes 720 can be evenly arranged along the Y-axis direction, and the locking holes 720 on the first locking plate 721 and the second locking plate 722 are staggered in sequence with the geometric center interval distance d. The range of the distance d can be smaller than the size of the locking hole 720 in the Y-axis direction.

[0096] In a specific embodiment, the locking hole 720 has a diameter of D, and the distance d is half of the diameter of the locking hole 720, that is, d=1 / 2D. The centers of the locking holes 720 on each locking plate 72 are arranged at intervals of distance D, and the locking holes 720 on the first locking plate 721 and the second locking plate 722 are staggered by 1 / 2D in the Y-axis direction. In this embodiment, the adjustment density of the adjustment mechanism 40 for adjusting the spacing is 1 / 2D, and the locking structure 70 can lock the sliding member 60 on the locking plate 72 every time the sliding member 60 slides a distance of 1 / 2D relative to the base 50.

[0097] In this way, by staggering the locking holes 720 on different locking plates 72 along the sliding direction of the sliding member 60 , the locking holes 720 are arranged more densely, further improving the adjustment accuracy.

[0098] See also Figure 6 In some embodiments, the adjustment mechanism 40 is provided with an indication structure 80 , and the indication structure 80 is used to indicate the sliding distance of the sliding member 60 relative to the base 50 .

[0099] Specifically, the position corresponding to the specific sliding distance of the sliding member 60 relative to the base 50 is calculated in advance, and is marked according to the calculation result to form the indication structure 80. The indication structure 80 can be indicated by a mechanical mechanism or an electronic display device.

[0100] In this way, the indicating structure 80 indicates the sliding distance of the sliding member 60 relative to the base 50, so as to facilitate observation of the distance between the first device 2100 and the second device 2200 during the debugging process.

[0101] See also Figure 6 In some embodiments, the indicating structure 80 includes a scale mark 81 and a pointer 82 , the scale mark 81 is disposed on the base 50 , and the pointer 82 is disposed on the sliding member 60 .

[0102] Specifically, the scale mark 81 can be set on the base 50 by silk screen printing, engraving, machining, etching and other processes. The direction of the increase or decrease of the scale on the scale mark 81 is consistent with the sliding direction of the sliding member 60. The pointer 82 slides with the sliding member 60, and the pointer 82 can move in the direction of the increase or decrease of the scale and point to different scales. The scale pointed by the pointer 82 in real time during the sliding process can be the distance between the first device 2100 and the second device 2200 at the same time. The debugging worker can judge whether the first device 2100 and the second device 2200 are debugged in place according to the scale pointed by the pointer 82 and lock the sliding member 60 in time.

[0103] In this way, by setting a scale mark 81 on the base 50 and a pointer 82 on the sliding member 60, the scale pointed to by the pointer 82 on the scale mark 81 can represent the sliding distance of the sliding member 60 relative to the base 50, thereby indicating the real-time distance between the first device 2100 and the second device 2200 through the indicating structure 80, thereby realizing visual debugging.

[0104] See also Figure 6 In some embodiments, the sliding member 60 is provided with a window 62 , the pointer 82 is disposed at the window 62 , and a portion of the scale mark 81 is exposed through the window 62 .

[0105] Specifically, the window 62 can be set above the connecting portion 53 and directly opposite to the scale mark 81. The window 62 can be formed by partially hollowing out the sliding member 60, and the pointer 82 can extend from the window 62. The pointer 82 can have a certain height difference with the scale mark 81 in the vertical direction and point to the scale mark 81 in the horizontal direction. During the sliding of the sliding member 60, part of the scale mark 81 corresponding to the sliding distance of the sliding member 60 is exposed through the window 62, and the window 62 can frame the reading range of the pointer 82 pointing to the scale mark 81.

[0106] In this way, the scale mark 81 and the pointer 82 are exposed through the window 62, so that the sliding distance can be visually measured during the sliding process of the sliding member 60.

[0107] See also Figure 5 In some embodiments, the adjustment mechanism 40 includes a guide assembly 90 , the guide assembly 90 includes a guide rail 91 and a slider 92 , the guide rail 91 is mounted on the base 50 , the slider 92 is slidably disposed on the guide rail 91 , and the sliding member 60 is fixedly connected to the slider 92 .

[0108] Specifically, the guide rail 91 can extend from the first end 51 to the second end 52 of the base 50, and the guide rail 91 can be laid on the connection portion 53 along the Y-axis direction. In other words, the guide rail 91 extends from the first device 2100 to the second device 2200 along the Y-axis direction. The slider 92 is fixedly connected to the sliding member 60, and the sliding member 60 is fixedly installed on the second device 2200. The slider 92 and the sliding member 60 can be fixedly connected by at least one of welding, bonding, fitting, threaded connection, and fixing member connection. Figure 5 In the illustrated embodiment, the sliding member 60 is disposed above the sliding block 92 . The sliding member 60 and the sliding block 92 may be provided with overlapping screw holes 63 . The sliding block 92 may be fixedly connected to the sliding member 60 by screwing screws into the screw holes 63 .

[0109] The guide rails 91 and the sliders 92 correspond to each other one by one, and the number of the guide rails 91 and the sliders 92 can be one group, two groups, or more than two groups. Figure 5In the illustrated embodiment, there are two groups of guide rails 91 and sliders 92, and the two groups of guide assemblies 90 are respectively arranged at both ends of the base 50 along the X-axis direction. The plurality of guide rails 91 can be arranged in parallel along the X-axis direction, so as to ensure that the relative position offset between the first device 2100 and the second device 2200 is as small as possible when the slider 92 and the sliding member 60 drive the first device 2100 to slide, and the first device 2100 and the second device 2200 are kept approximately parallel to each other when the spacing is adjusted.

[0110] The sliding member 60 and the slider 92 can slide from the second end 52 of the base 50 to the first end 51 on the guide rail 91, driving the second device 2200 to approach the first device 2100 along the Y-axis direction. The sliding member 60 and the slider 92 can slide toward the second end 52 on the guide rail 91, driving the second device 2200 to move away from the first device 2100 along the Y-axis direction.

[0111] In this way, by cooperating with the guide rail 91 and the slider 92, the sliding member 60 can slide smoothly along the preset direction, so that the adjustment mechanism 40 can adjust the distance between the first device 2100 and the second device 2200 in the preset direction and improve the stability of the adjustment mechanism 40.

[0112] See also Figure 5 In some embodiments, the adjustment mechanism 40 includes a stopper 93 , which is disposed at an end of the guide rail 91 in the length direction.

[0113] Specifically, the stopper 93 can be arranged at the end of each guide rail 91 along the Y-axis direction, that is, the length direction of the guide rail 91. The stopper 93 can be fixed on the base 50 and protrude upward, slightly higher than a certain distance from the horizontal plane where the guide rail 91 is located, so that when the slider 92 slides to the end of the guide rail 91, it can be blocked by the stopper 93 and will not leave the guide rail 91. The stopper 93 can be in the form of a sheet and can fit the side of the base 50, thereby saving installation space.

[0114] In this way, by providing the stopper 93 in the longitudinal direction of the guide rail 91 , the slider 92 is prevented from coming out.

[0115] In addition, the guide rail 91 can be a ball guide rail 91, and the stopper 93 can also prevent the balls from falling out.

[0116] Please refer again Figure 4 The present application provides a production device 2000, which includes a first device 2100, a second device 2200 spaced apart from the first device 2100, and an adjustment mechanism 40 of any of the above-mentioned embodiments.

[0117] Specifically, the adjustment mechanism 40 can adjust the distance between the first device 2100 and the second device 2200 to adapt to different product specifications. The production equipment 2000 can be used to glue the battery cell assembly after welding. The welded battery cell 100 can be placed on the first device 2100 and the second device 2200, and then the insulating film is pasted on the welding point of the pole ear 22 through the glue sticking assembly (not shown). The same set of production equipment 2000 can be used to produce different battery cells 100. The distance between the first device 2100 and the second device 2200 is adjusted according to product specification data such as the size of the battery cell 100, the size of the pole ear 22, and the spacing between the positive and negative pole ears 22 to ensure the accuracy of the glue sticking position and improve the product yield.

[0118] The production equipment 2000 provided in the present application can quickly and conveniently adjust the distance between the first device 2100 and the second device 2200 through the adjustment mechanism 40, thereby helping to improve production efficiency and enhance product quality.
