[0068] Specifically, Figure 1 , Figure 2 As shown, the battery lower box is formed by splicing a plurality of connecting members 900 into a frame shape and then welding. According to the design size of the battery lower box, the fixed positioning device 210 is installed to one side of the preset position of the connecting member 900 through the mounting hole 101 in cooperation with screws, pins, etc., and the movable positioning device 220 is installed to the other side of the preset position of the connecting member 900, and a spacing distance is reserved between the fixed positioning device 210 and the movable positioning device 220 for the connecting member 900 to be placed from top to bottom. The pressing assembly 300 is installed to the preset position of the connecting member 900 through the mounting hole 101 in cooperation with screws, pins, etc. On the side of the position, the clamping assembly 300 does not interfere with the channel through which the connecting member 900 is inserted from top to bottom. The connecting member 900 is inserted according to the layout of the lower battery box, and the side of the connecting member 900 is abutted against the fixed positioning device 210 for positioning. Then, the other side of the connecting member 900 is pressed against the movable positioning device 220 to complete the horizontal positioning of the connecting member 900. Finally, the connecting member 900 is pressed downward by the clamping member 320, and the connecting member 900 is clamped between the clamping member 320 and the workbench 100, thereby completing the positioning of the connecting member 900 and the lower battery box before welding.

[0071] Specifically, the reference mark can be a hole position, a specific pattern, a raised structure, etc., which can cooperate with a robot to meet the requirements of automatic installation of the horizontal positioning component, the clamping component 300 and the connecting member 900.

[0072] Of course, in the specific implementation process, the horizontal positioning assembly, the clamping assembly 300 and the connecting member 900 can be installed manually, which will not be described in detail here.

[0073] like Figure 3 As shown, in some embodiments of the present invention, the workbench 100 is provided with a plurality of mounting holes 101 distributed in a transverse array and a longitudinal array to meet the installation requirements of the horizontal positioning assembly and the clamping assembly 300 at different positions, so that the present invention can be applicable to battery lower boxes of various specifications.

[0074] It can be understood that in some embodiments of the present invention, the workbench 100 can be provided with a plurality of installation grooves distributed vertically and horizontally, and can also meet the installation requirements of the horizontal positioning assembly and the clamping assembly 300 at different positions in combination with bolt assemblies, pins, etc.

[0075] like Figure 4 As shown, in some embodiments of the present invention, the fixed positioning device 210 includes a fixed positioning seat 211, which can be installed to the workbench 100 through the mounting hole 101 or the mounting groove, and the fixed positioning seat 211 is provided with a pressing portion that can be pressed against the side of the connecting member 900, and the positioning of the side of the connecting member 900 is achieved through the pressing portion.

[0076] like Figure 4 As shown, in some embodiments of the present invention, the fixed positioning seat 211 is provided with an elongated hole for the mounting screw or mounting pin to pass through and connect to the mounting hole 101 , so as to facilitate adjustment of the mounting position of the fixed positioning seat 211 .

[0077] Specifically, the mounting holes 101 are distributed in a vertical and horizontal array, and there must be a gap between adjacent mounting holes 101. The installation position of the fixed positioning device 210 can only be at the set hole position. By configuring the elongated holes, the position of the pressing part can be slidably adjusted to eliminate the influence of the gap between the mounting holes 101.

[0078] like Figure 4 As shown, in some embodiments of the present invention, the fixed positioning seat 211 is L-shaped, wherein the bottom thereof is used to set a long hole, and the vertical portion thereof forms a pressing portion, and the structure is simple and reasonable.

[0079] It can be understood that in some embodiments of the present invention, the fixed positioning seat 211 can also be a square, a right triangle, etc., which will not be described in detail here.

[0080] like Figure 4 As shown, in some embodiments of the present invention, the movable positioning device 220 includes a movable positioning seat 221, and the movable positioning seat 221 can be installed to the workbench 100 through the mounting hole 101 or the mounting groove. The movable positioning seat 221 is provided with a side pressure screw 222 through threaded cooperation, and the side pressure screw 222 is provided with a side pressure piece 223 that can be pressed against the connecting member 900. After the movable positioning seat 221 is fixed to the workbench 100, the position of the side pressure piece 223 can be movably adjusted by rotating the side pressure screw 222 to press the connecting member 900 between the fixed positioning device 210 and the movable positioning device 220.

[0081] like Figure 4 As shown, in some embodiments of the present invention, the movable positioning seat 221 is provided with an elongated hole for the mounting screw or mounting pin to pass through and connect to the mounting hole 101 , so as to facilitate the adjustment of the mounting position of the movable positioning seat 221 .

[0082] Specifically, the mounting holes 101 are distributed in a vertical and horizontal array, and there must be a gap between adjacent mounting holes 101. The installation position of the movable positioning device 220 can only be at the set hole position. By configuring the elongated hole, the position of the side pressure screw 222 can be slidably adjusted to eliminate the influence of the gap between the mounting holes 101.

[0083] like Figure 4 As shown, in some embodiments of the present invention, the movable positioning device 220 is L-shaped, wherein the bottom thereof is used to set a long hole, the side pressure screw 222 is set in the vertical part, a handle is set at one end of the side pressure screw 222, and a side pressure piece 223 is set at the other end.

[0086] Specifically, the mounting holes 101 are distributed in a vertical and horizontal array, and there must be a gap between adjacent mounting holes 101. The installation position of the clamping seat 310 can only be at the set hole position.

The reaction force of the balancing screw 322 on the clamping piece 320 can offset the reaction force on the clamping piece 320 when the pressing end 323 is pressed down, thereby balancing the clamping force of the clamping assembly 300, and the clamping effect is good.

[0088] When working, by rotating the pressing screw 321, the pressing end 323 of the clamping piece 320 is pressed against the upper end surface of the connecting member 900. At this time, the pressing end 323 reacts on the clamping piece 320, so that a lateral pressure or a lateral thrust is formed between the clamping piece 320 and the pressing screw 321. The hole position of the clamping piece 320 or the pressing screw 321 is very easy to deform. At this time, the balancing screw 322 can be rotated to act on the other end of the clamping piece 320, so that the clamping piece 320 can be roughly restored to a horizontal state, so that the reaction force of the clamping piece 320 on the pressing screw 321 is applied to the head of the pressing screw 321, thereby effectively protecting the clamping structure, and enabling the pressing end 323 to roughly vertically press down the upper end surface of the connecting member 900, thereby achieving a better clamping effect.

[0105] In some embodiments of the present invention, the support member 620 is connected to the support seat 610 by threaded fitting, and the support height of the support member 620 can be flexibly adjusted by rotating the support member 620 to meet the support requirements of the bottom of the connecting component 900 at different heights.

[0106] A method for detecting a flexible welding platform of a multifunctional battery lower box according to a second aspect of the present invention;

[0107] Each connecting member 900 is equipped with a group of pressing assemblies 300, a≥2, and the pressing assembly 300 is equipped with a first pressure sensor capable of detecting the pressure acting on the connecting member 900, and the pressing forces of the pressing assembly 300 acting on the connecting member 900 are N1, N2...Na respectively;

[0108] Each connecting member 900 is configured with b groups of bottom support components 600, b≥2, and the bottom support components 600 are configured with a second pressure sensor capable of detecting the pressure when being pressed by the connecting member 900, and the pressing forces of the connecting member 900 acting on the bottom support components 600 are P1, P2...Pb respectively;

[0109] The average pressing force of the bottom support assembly 600 acting on each connecting member 900 is P0, and the gravity of the connecting member 900 is G;

[0110]

[0111] The difference between the pressing force detected by the second pressure sensor and the average pressing force is ΔP k ;

[0112] ΔP k =P k -P0, k = 1, 2, ... b;

[0113] Setting the qualified threshold value of the compression uniformity of the connecting member (900) to Z, Z=0.001 to 0.01;

[0114] like The connecting member 900 meets the welding requirements;

[0115] like The connection member 900 does not meet the welding requirements.

[0116] Since the connecting member 900 is a long member, the clamping assembly 300 needs to be configured in multiple groups and distributed at intervals, so that the clamping force acting on the connecting member 900 is distributed at intervals. The bottom of the connecting member 900 is also not a flat surface. When supported by the bottom support assembly 600, it is difficult to ensure the straightness of the connecting member 900. In the above detection method, by calculating the theoretical average clamping force P0 of each bottom support assembly 600 and the actual clamping force P k The difference ΔP k , and the difference ΔP k The ratio of the theoretical average clamping force P0 of each bottom support assembly 600 is compared with the qualified threshold value Z to determine whether the compression condition of the connecting member 900 meets the straightness requirement and whether it reaches the weldable standard, so as to facilitate the operator to perform welding processing.

[0117] Specifically, the sum of the clamping forces of all clamping assemblies 300 plus the gravity of the connecting member 900 itself is the total pressure acting on all bottom support assemblies 600. The total pressure is then divided by the number b of the bottom support assemblies 600 to obtain the theoretical average clamping force P0 of each bottom support assembly 600.

[0118] In some embodiments of the present invention, Z=0.005. Of course, in the specific implementation process, Z can be set to 0.001, 0.002, 0.003, 0.003, 0.004, 0.006, 0.007, 0.008, 0.009, 0.01, etc. according to actual processing requirements, which will not be described in detail here.

[0119] In some embodiments of the present invention, the multifunctional battery lower box flexible welding platform is equipped with a control system and a display module. The control system is connected to each pressure sensor and compares the detection results, and displays the results on the display module to facilitate the operator's operation.

[0120] like Fig.12 , Fig.13 As shown, in some embodiments of the present invention, the projections of the clamping assembly 300 and the bottom support assembly 600 acting on the same connecting member 900 on the workbench 100 are staggered, that is, the clamping assembly 300 and the bottom support assembly 600 are not on the same vertical line, so as to avoid direct alignment and offset of the clamping forces, which would affect the straightness determination of the connecting member 900.

[0121] In some embodiments of the present invention, the multifunctional battery lower box flexible welding platform is equipped with a control system and a display module. The control system is connected to each pressure sensor and displays the pressure detection result on the display module. When the connecting member 900 does not meet the welding requirements, the user can adjust the pressing force of the pressing assembly 300 at the corresponding position according to the pressure detection result on the display module, so as to facilitate the operator to level the connecting member 900.

[0122] Specifically, when the clamping force of the bottom support assembly 600 at the set position is too small, the clamping force of the clamping assembly 300 on both sides of the bottom support assembly 600 is increased by a corresponding adjustment. When the clamping force of the bottom support assembly 600 at the set position is too large, the clamping force of the clamping assembly 300 on both sides of the bottom support assembly 600 is reduced by a corresponding adjustment.

[0123] like Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments of the present invention, the clamping piece 320 is an elongated piece, the middle part of the clamping piece 320 is connected to the clamping seat 310 by a pressing screw 321, one end of the clamping piece 320 is a pressing end 323, the first pressure sensor is arranged at the pressing end 323, and the other end of the clamping piece 320 is provided with a balancing screw 322 through threaded cooperation, the balancing screw 322 is pressed to the clamping seat 310, and the reaction force of the balancing screw 322 on the clamping piece 320 can offset the reaction force on the clamping piece 320 when the pressing end 323 is pressed down, thereby balancing the clamping force of the clamping assembly 300, achieving a good clamping effect, and ensuring the accuracy of the pressure detection result of the first pressure sensor.

[0124] When working, by rotating the pressing screw 321, the pressing end 323 of the clamping piece 320 is pressed against the upper end surface of the connecting member 900. At this time, the pressing end 323 reacts on the clamping piece 320, so that a lateral pressure or a lateral thrust is formed between the clamping piece 320 and the pressing screw 321. The hole position of the clamping piece 320 or the pressing screw 321 is very easy to deform. At this time, the balancing screw 322 can be rotated to act on the other end of the clamping piece 320 so that the clamping piece 320 can be roughly restored to a horizontal state, so that the reaction force of the clamping piece 320 on the pressing screw 321 is applied to the head of the pressing screw 321, thereby effectively protecting the clamping structure and enabling the pressing end 323 to roughly vertically press down the upper end surface of the connecting member 900, thereby ensuring the accuracy of the pressure detection result of the first pressure sensor.

[0125] In some embodiments of the present invention, the pressing member 320 is provided with a level detection module to facilitate the user to refer to and adjust the balance screw 322 .

[0126] Of course, the invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
