[0042] First, it should be noted that the X, Y, and Z directions mentioned in the embodiments of this application are referred to in the appendix. Figures 1-5 The marked directions; wherein the axes in the X direction, Y direction, and Z direction intersect each other.

[0043] like Figure 1 and Figure 2As shown, according to a first aspect of the embodiments of this application, a heat flux density detection mechanism 100 is provided, including an installation component 1, a guide component 2, and a detection component 3; the guide component 2 is disposed on the installation component 1; the detection component 3 includes a bracket 31 and a heat flux sensor 32, the bracket 31 is slidably connected to the guide component 2, the heat flux sensor 32 is disposed on the bracket 31, and the heat flux sensor 32 is arranged at intervals from the installation component 1.

[0044] The heat flux density detection mechanism 100 in this application can be used to detect the heat flux density inside the lamp box 300 in the welding apparatus, and adjust the temperature inside the lamp box 300 by detecting the heat flux density, so as to improve the welding quality of the welding apparatus.

[0045] like Figure 1 and Figure 2 As shown, the heat flux density detection mechanism 100 includes a mounting assembly 1, a guide assembly 2, and a detection assembly 3. The guide assembly 2 is mounted on the mounting assembly 1, which provides mounting and support for the guide assembly 2. The mounting assembly 1 can be a mounting bracket or a mounting plate; in this embodiment, a mounting plate is used. The detection assembly 3 includes a bracket 31 and a heat flux sensor 32. The heat flux sensor 32 is mounted on the bracket 31, which is mounted on the guide assembly 2. The bracket 31 and the guide assembly 2 are slidably connected, so the heat flux sensor 32 can move relative to the guide assembly 2 in a preset direction. The heat flux sensor 32 and the mounting assembly 1 are spaced apart in the Z direction, so there is a space between the heat flux sensor 32 and the mounting assembly 1. The space is used to place the conveying mechanism 200 or the lamp box 300, thereby saving the space occupied by the heat flux density detection mechanism 100 and avoiding the inability to place the heat flux density detection mechanism 100 due to the small space between the lamp box 300 and the conveying mechanism 200. Furthermore, by moving the detection assembly 3 to detect the heat flux density at various points inside the lamp box 300 of the welding device, accurate temperature distribution data inside the lamp box 300 can be obtained.

[0046] To illustrate with a specific embodiment, when the light box 300 to be tested has only one lamp tube 301, and the length direction of the lamp tube 301 is the Y direction; in this case, the guide assembly 2 only includes the second guide member 22, the bracket 31 is slidably connected to the second guide member 22, the bracket 31 can move relative to the second guide member 22 in the Y direction, and the heat flow sensor 32 is set on the bracket 31. When the bracket 31 moves in the Y direction, multiple sampling points G are designed according to the length of the lamp tube 301. The bracket 31 can drive the heat flow sensor 32 to move in the length direction of the lamp tube 301, so that the heat flow density of the lamp tube 301 can be detected at the sampling point G by the heat flow sensor 32, so as to realize the heat flow density detection of the heating area of ​​the lamp tube 301 in the light box 300, thereby obtaining accurate temperature distribution data of the light box 300 during the welding process.

The first guide member 21 is disposed on the mounting assembly 1, the second guide member 22 is slidably connected to the first guide member 21, and the detection assembly 3 is slidably connected to the second guide member 22. The moving direction of the detection assembly 3 is different from the moving direction of the second guide member 22; specifically, the guide assembly 2 includes... The assembly includes a first guide member 21 and a second guide member 22. The first guide member 21 is mounted on the mounting assembly 1, and the second guide member 22 is slidably connected to the first guide member 21. The second guide member 22 can move relative to the first guide member 21 in the X direction. The detection assembly 3 is slidably connected to the second guide member 22 and can move relative to the second guide member 22 in the Y direction. In other words, the heat flow sensor 32 can move in both the X and Y directions to detect the heat flow density of the heating area of ​​each lamp tube 301 in the lamp box 300, thereby obtaining accurate temperature distribution data of the lamp box 300 during the welding process.

[0048] In one optional embodiment, the first guide member 21 includes a first guide rail 211 and a second guide rail 212, the first guide rail 211 and the second guide rail 212 being spaced apart along the Y direction on the mounting assembly 1; the second guide member 22 includes a first slider 222, a second slider 223 and a third guide rail 221, the first slider 222 being slidably connected to the first guide rail 211 along the X direction, the second slider 223 being slidably connected to the second guide rail 212 along the X direction, one end of the third guide rail 221 being connected to the first slider 222, and the other end of the third guide rail 221 being connected to the second slider 223; the detection assembly 3 further includes a third slider 33, the third slider 33 being disposed on the bracket 31, and the third slider 33 being slidably connected to the third guide rail 221 along the Y direction.

[0049] like Figure 1 and Figure 2As shown, the first guide member 21 includes a first guide rail 211 and a second guide rail 212. The first guide rail 211 and the second guide rail 212 are spaced apart on the mounting assembly 1 along the Y direction.

The second guide member 22 includes a first slider 222, a second slider 223, and a third guide rail 221. The first slider 222 is slidably connected to the first guide rail 211 and can move relative to the first guide rail 211 along the X direction. The second slider 223 is slidably connected to the second guide rail 212 and can move relative to the second guide rail 212 along the X direction. 2. Moving along the X direction, one end of the third guide rail 221 is set on the first slider 222, and the other end of the third guide rail 221 is set on the second slider 223, thereby improving the stability and balance of the third guide rail 221 when sliding; the length direction of the third guide rail 221 is the same as the Y direction, the third slider 33 is slidably connected to the third guide rail 221, and the third slider 33 can move relative to the third guide rail 221 along the Y direction; the bracket 31 is set on the third slider 33, so the heat flow sensor 32 can move in both the X and Y directions; in this embodiment, the structure of the first guide member 21 and the second guide member 22 is simple and easy to install.

[0050] In an optional embodiment, the heat flux density detection mechanism 100 further includes a first driving component and a second driving component. The driving end of the first driving component is connected to the first slider 222 or the second slider 223, and the driving end of the second driving component is connected to the third slider 33. Specifically, the driving end of the first driving component is connected to the first slider 222 or the second slider 223, and the first driving component can drive the first slider 222 or the second slider 223 to move relative to the first guide rail 211 or the second guide rail 212 in the X direction, thereby driving the third guide rail 221 to move in the X direction. The driving end of the second driving component is connected to the third slider 33, and the second driving component can drive the third slider 33 to move relative to the third guide rail 221 in the Y direction. In this embodiment, the first driving component and the second driving component can realize automatic control of the movement of the detection component 3 in the X and Y directions, which can improve the detection efficiency.

[0051] The first drive component can be a linear motor, a pneumatic cylinder, or a hydraulic cylinder; the second drive component can be a linear motor, a pneumatic cylinder, or a hydraulic cylinder.

[0052] In an optional embodiment, the heat flux density detection mechanism 100 further includes a connecting component 4, a fourth slider 5, and a pull rod 6. The connecting component 4 is disposed on the mounting component 1. The fourth slider 5 is slidably connected to the connecting component 4 in the Y direction. One end of the pull rod 6 is connected to the bracket 31, and the pull rod 6 and the fourth slider 5 are slidably connected in the X direction.

[0053] like Figure 1 and Figure 2 As shown, the heat flux density detection mechanism 100 also includes a connecting component 4, a fourth slider 5, and a pull rod 6. The connecting component 4 is mounted on the mounting component 1. The fourth slider 5 is slidably connected to the connecting component 4 in the Y direction, and the fourth slider 5 can move relative to the connecting component 4 in the Y direction. One end of the pull rod 6 is connected to the bracket 31, and the pull rod 6 is slidably connected to the fourth slider 5. The pull rod 6 can move relative to the fourth slider 5 in the X direction. In this embodiment, the operator moves the pull rod 6 in the X direction, which drives the bracket 31 to move relative to the fourth slider 5 in the X direction, thereby driving the heat flux sensor 32 to move in the X direction. The operator also moves the pull rod 6 in the Y direction, which drives the bracket 31 and the fourth slider 5 to move relative to the connecting component 4 in the Y direction, thereby driving the heat flux sensor 32 to move in the X direction. In this embodiment, the pull rod 6 enables manual operation of the detection component 3 in the X and Y directions. This method is simple to operate and allows for easy changes to the sampling point G as needed, providing greater flexibility.

[0054] In one optional embodiment, the connecting assembly 4 includes a first mounting portion 41, a second mounting portion 42, and a mounting rod 43. One end of the first mounting portion 41 is angularly connected to one end of the second mounting portion 42, and the other end of the first mounting portion 41 is disposed on the mounting assembly 1. The mounting rod 43 is disposed on the other end of the second mounting portion 42, and the fourth slider 5 is slidably connected to the mounting rod 43. Specifically, the first mounting portion 41 and the second mounting portion 42 are angularly connected. Through the first mounting portion 41, the second mounting portion 42 and the mounting assembly 1 are arranged at intervals in the X direction, and the mounting rod 43 is disposed on the second mounting portion 42. The fourth slider 5 is slidably connected to the mounting rod 43, so there is a space for movement between the fourth slider 5 and the mounting assembly 1. The pull rod 6 is slidably connected to the fourth slider 5, and the end of the pull rod 6 away from the detection assembly 3 has a certain space with the mounting assembly 1. The light box 300 is set at the location of the mounting assembly 1, so there is a certain space between the pull rod 6 and the light box 300. When the operator drives the detection assembly 3 to move through the pull rod 6, the operator has a certain distance from the light box 300 to avoid the operator being burned by the temperature of the light box 300. In addition, a second scale is set on the mounting rod 43 so that the movement distance of the detection assembly 3 can be clearly seen through the second scale.

[0055] In one specific implementation, such as Figure 1 As shown, a groove 51 is provided on the fourth slider 5. The groove 51 passes through the fourth slider 5 in the X direction. The pull rod 6 is located in the groove 51 and can move relative to the groove 51 in the X direction. The groove 51 can restrict the pull rod 6 from moving relative to the fourth slider 5 in the Y direction.

[0056] In one alternative embodiment, the first mounting part 41 includes a first connecting plate, the second mounting part 42 includes a second connecting plate, the first connecting plate and the second connecting plate are connected at an angle, and the mounting rod 43 is disposed on the second connecting plate.

[0057] In another alternative embodiment, the first mounting portion 41 includes a first connecting rod 411 and a second connecting rod 412, the first connecting rod 411 and the second connecting rod 412 being arranged at intervals along the Y direction; the second mounting portion 42 includes a third connecting rod 421 and a fourth connecting rod (not shown in the figure, please refer to the appendix). Figure 2 The third connecting rod 421 and the fourth connecting rod are arranged at intervals along the Y direction; one end of the first connecting rod 411 is connected at an angle to one end of the third connecting rod 421, and the other end of the first connecting rod 411 is connected to the mounting assembly 1; one end of the second connecting rod 412 is connected at an angle to one end of the fourth connecting rod, and the other end of the second connecting rod 412 is connected to the mounting assembly 1; the mounting rod 43 is connected to the other ends of the third connecting rod 421 and the fourth connecting rod. In this embodiment, the weight of the connecting assembly 4 can be reduced, and the connection stability of the connecting assembly 4 can be improved by setting the first connecting rod 411, the second connecting rod 412, the third connecting rod 421, and the fourth connecting rod.

[0058] In one optional embodiment, the pull rod 6 is provided with a first scale; specifically, the length direction of the pull rod 6 is the X direction, and the first scale is set along the length direction of the pull rod 6. When the pull rod 6 moves relative to the fourth slider 5 in the X direction, the distance that the pull rod 6 moves in the X direction can be determined according to the first scale, which can accurately determine the moving distance of the heat flux sensor 32, thereby improving the detection accuracy of the heat flux density detection mechanism 100.

[0059] In one optional embodiment, the mounting rod 43 is provided with a second scale; specifically, the length direction of the mounting rod 43 is the Y direction, and the second scale is set along the length direction of the mounting rod 43. When the fourth slider 5 moves relative to the mounting rod 43 in the Y direction, the distance that the pull rod 6 moves in the Y direction can be determined according to the second scale, which can accurately measure the moving distance of the heat flux sensor 32, thereby improving the detection accuracy of the heat flux density detection mechanism 100.

[0060] In one specific embodiment, the heat flux density detection mechanism 100 further includes a first locking member 7, which is capable of restricting the movement of the pull rod 6 relative to the fourth slider 5 in the X direction.

[0061] In another specific embodiment, the heat flux density detection mechanism 100 further includes a second locking member 8, which is capable of restricting the fourth slider 5 from moving relative to the mounting rod 43 in the Y direction.

[0062] like Figure 1 and Figure 2 As shown, in one specific embodiment, the heat flux density detection mechanism 100 further includes a first locking member 7 and a second locking member 8. The first locking member 7 can restrict the movement of the pull rod 6 relative to the fourth slider 5 in the X direction. Specifically, the first locking member 7 is disposed on the fourth slider 5 and is detachably connected to the pull rod 6. When the first locking member 7 is connected to the pull rod 6, it can restrict the movement of the pull rod 6 relative to the fourth slider 5, thereby restricting the movement of the pull rod 6 in the X direction. When the first locking member 7 is not connected to the pull rod 6, it does not restrict the movement of the pull rod 6 relative to the fourth slider 5, and the pull rod 6 can move in the X direction. The second locking member 8 can restrict the movement of the fourth slider 5 relative to the mounting rod 43 in the Y direction. Specifically, the second locking member 8 is disposed on the fourth slider 5 and is detachably connected to the mounting rod 43. When the second locking member 8 is connected to the mounting rod 43, it can restrict the movement of the fourth slider 5 in the Y direction. When the mounting rod 43 moves along the Y direction, the second locking member 8 is not connected to the mounting rod 43, thus not restricting the fourth slider 5 from moving relative to the mounting rod 43 along the Y direction. Taking this embodiment as an example, when the detection component 3 detects any sampling point along the length direction of a lamp tube 301, the first locking member 7 restricts the pull rod 6 from moving relative to the fourth slider 5 along the X direction to prevent the detection component 3 from moving along the X direction to other lamp tubes 301. When the detection component 3 reaches the last sampling point of a lamp tube 301, the second locking member 8 is locked to restrict the fourth slider 5 from moving relative to the mounting rod 43 along the Y direction. The first locking member 7 is released, and the pull rod 6 moves the detection component 3 along the X direction to the next lamp tube 301. The first locking member 7 is locked again, the second locking member 8 is released, and the pull rod 6 continues to drive the detection component 3 to move along the Y direction until the heat flux density measurement of the second lamp tube 301 is completed.

[0063] The first locking element 7 can be locked with screws or with a snap-fit; the second locking element 8 can be locked with screws or with a snap-fit.

[0065] In one alternative implementation, such as Figure 3 As shown, the light box 300 is disposed between the heat flow sensor 32 and the mounting assembly 1, with the heat flow sensor 32 facing the bottom of the light box 300. The conveying mechanism 200 and the heat flow density detection mechanism 100 are spaced apart. Specifically, the light box 300 is disposed between the heat flow sensor 32 and the mounting assembly 1, and a lamp tube 301 is provided inside the light box 300, with the lamp tube 301 facing the bottom of the light box 300, that is, the heat flow sensor 32 faces the lamp tube 301, so as to detect the heat flow density of the lamp tube 301 inside the light box 300. The conveying mechanism 200 and the heat flow density detection mechanism 100 are spaced apart along the Z direction, with the conveying mechanism 200 located below the heat flow density detection mechanism 100 in the Z direction, that is, the conveying mechanism 200 located below the light box 300 in the Z direction, so that the lamp tube 301 in the light box 300 can provide the welding temperature required for the battery cells and welding strips located on the conveying mechanism 200.

[0066] In another alternative implementation, such as Figure 4 As shown, the light box 300 and the heat flux density detection mechanism 100 are spaced apart. The heat flux sensor 32 faces the bottom of the light box 300, and the conveying mechanism 200 is located between the heat flux sensor 32 and the mounting assembly 1. Specifically, the light box 300 and the heat flux density detection mechanism 100 are spaced apart along the Z direction. The light box 300 is located above the heat flux density detection mechanism 100, and the heat flux sensor 32 is located below the light box 300 relative to the mounting assembly 1, so as to detect the heat flux density of the lamp tube 301 inside the light box 300. The conveying mechanism 200 is located between the heat flux sensor 32 and the mounting assembly 1, and the conveying mechanism 200 is located below the light box 300 in the Z direction, so that the lamp tube 301 in the light box 300 can provide the welding temperature required for the battery cells and welding strips located on the conveying mechanism 200.

[0067] In one optional embodiment, the guide component 2 includes a first guide member 21, the size of the first guide member 21 in the X direction being larger than the size of the light box 300 in the X direction. That is, the size of the light box 300 in the X direction is smaller than the size of the first guide rail 211 in the X direction and also smaller than the size of the second guide rail 212 in the X direction. When the welding device is working, the detection component 3 can move out of the area where the light box 300 is located by moving along the first guide member 21 in the X direction, so as to avoid affecting the normal operation of the light box 300.

[0068] In one specific implementation, the heat flux density detection mechanism 100 performs the following detection steps on the light box 300:

[0069] S1, install the heat flow sensor 32 on the bracket 31, connect the heat flow sensor 32 to the cooling water pump and digital display instrument, loosen the first locking member 7 and the second locking member 8, and move the heat flow sensor 32 to the edge position of the first guide member 21 and the second guide member 22 through the pull rod 6.
