Description

Technical Field

[0001] The utility model relates to the technical field of battery welding processing, in particular to an auxiliary standard block for adjusting a welding fixture. Background Art

[0002] When welding prismatic batteries, a welding jig is typically used to secure them. To ensure effective welding, existing welding jigs typically use a dummy battery, or a battery model, placed inside the jig. The spacing between the two clamping plates of the welding jig along the thickness of the battery is adjusted based on the thickness of the battery model, and the spacing between the two clamping plates along the length of the battery is adjusted based on the width of the battery model. After the spacing is adjusted, the dummy battery is removed, and the battery to be welded is then placed within the adjusted accommodation area of ​​the welding jig. Then, welding can begin.

[0003] During actual operation, due to differences in individual operation, the side pressing force of the actually adjusted welding fixture on the battery in the width direction and the side pressing force in the thickness direction of the battery may be quite different, resulting in inconsistent rebound height of the battery after being compressed, so that the upper end face of the battery, i.e. the welding surface, is in a non-horizontal state, and the movement of the welding gun is in the horizontal direction. Therefore, the welding effect of the battery will be affected during welding. Utility Model Content

The second pressure sensor is connected to the display via a second wire passing through the fourth opening. The X direction, the Y direction, and the Z direction are perpendicular to each other.

[0010] As a further solution of the auxiliary standard block for adjusting the welding fixture, the first mounting slot includes a first main slot and a first avoidance slot that are connected to each other, the first avoidance slot being located on a side of the first main slot facing away from the welding fixture along the Z direction, the first pressure sensor being fixed in the first main slot by a bolt, the first wire being located in the first avoidance slot, the first main slot having the first opening, and the first avoidance slot having the second opening;

[0011] The second mounting groove includes a second main groove and a second avoidance groove that are connected to each other. The second avoidance groove is located on the side of the second main groove away from the welding fixture along the Z direction. The second pressure sensor is fixed in the second main groove by bolts. The second wire is located in the second avoidance groove.

[0012] As a further solution of an auxiliary standard block for adjusting a welding fixture, the first avoidance groove has a first opening consistent with the direction of the first opening, the first opening connects the first opening and the second opening, and the second avoidance groove has a second opening consistent with the direction of the third opening, the second opening connects the third opening and the fourth opening.

[0013] As a further solution of the auxiliary standard block for adjusting the welding fixture, both ends of the second main groove along the X direction pass through the battery contoured body.

[0014] As a further solution of the auxiliary standard block for adjusting the welding fixture, the battery contoured body is penetrated by a plurality of through-hole structures along the X direction.

[0015] As a further solution of the auxiliary standard block for adjusting the welding fixture, the through-hole structure includes a plurality of first through-holes and a plurality of second through-holes, the first through-holes and the second through-holes are symmetrical with respect to at least one center line of the battery contoured body, the length of the center line extends along the Y direction or along the Z direction, and the X direction, the Y direction and the Z direction are perpendicular to each other.

[0018] Beneficial effects:

[0019] The utility model arranges pressure sensors on the sides of the battery profiling body respectively. When the welding fixture clamps the auxiliary standard block, the detected pressure value is displayed on the display. By observing whether the pressure values ​​are consistent, the clamping plate of the welding fixture can be adjusted, and finally the pressures on the first side and the second side of the battery profiling body are kept consistent or do not exceed the target value range. After the welding fixture is adjusted, the auxiliary standard block is taken out and the battery to be welded is placed in the welding fixture. At this time, the pressures on the sides of the battery to be welded are consistent, and the amplitude of the battery's rebound after being pressurized is also consistent, which eventually makes the height of the upper reference surface of the battery (the side of the battery facing away from the welding fixture along the Z direction) consistent, so the battery welding quality rate can be effectively improved during welding.

[0020] In the present invention, the first avoidance groove has a second opening and a first opening. When the clamping plate of the welding fixture facing the first side presses the first side, a certain airflow resistance will be generated. By opening the first opening, the airflow can enter the first avoidance groove from the first opening and be led out along the second opening, thereby avoiding the airflow from being trapped between the first side and the corresponding clamping plate and causing the detection data of the corresponding first pressure sensor to be distorted; the second avoidance groove has a fourth opening and a second opening. When the clamping plate of the welding fixture facing the second side presses the second side, a certain airflow resistance will also be generated. By opening the second opening, the airflow can enter the second avoidance groove from the second opening and be led out along the fourth opening, thereby avoiding the airflow from being trapped between the second side and the corresponding clamping plate and causing the detection data of the corresponding second pressure sensor to be distorted.

[0021] When the clamp of the welding fixture presses the first side surface of the battery contoured body with a relatively large area, the airflow resistance generated is relatively large. The utility model can quickly introduce part of the airflow into the through-hole structure by opening multiple through-hole structures passing through the first side surface, thereby improving the detection accuracy of the pressure sensor.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and the like are used solely for descriptive purposes and do not have any special meaning.

[0037] like Figure 1 and Figure 2 As shown, this embodiment provides an auxiliary standard block for adjusting a welding fixture, comprising a battery shaped body 100, a first pressure sensor 200, a second pressure sensor 300, and a display 400 for displaying pressure values. The length of the battery shaped body 100 extends along the X direction, and the width of the battery shaped body 100 extends along the Y direction. The battery shaped body 100 has two first side surfaces 101 disposed opposite to each other along the X direction, and at least one first pressure sensor 200 is installed on at least one first side surface 101. The battery shaped body 100 has two second side surfaces 102 disposed opposite to each other along the Y direction, and at least one second pressure sensor 300 is installed on at least one second side surface 102. The detection end surface of the first pressure sensor 200 is in the same plane as the corresponding first side surface 101, and the detection end surface of the second pressure sensor 300 is in the same plane as the corresponding second side surface 102. The display 400 is connected to the first pressure sensor 200 and the second pressure sensor 300, respectively. The X direction is perpendicular to the Y direction.

[0038] It can be understood that the shape and size of the battery contour body 100 of this embodiment are consistent with the shape and size of the battery to be welded. The auxiliary standard block is placed in the welding fixture in the open state, and then the welding fixture is clamped. At this time, the first pressure sensor 200 installed on the first side 101 detects the pressure applied to the first side 101, and the second pressure sensor 300 installed on the second side 102 detects the pressure applied to the second side 102. The detected pressure values ​​are displayed on the display 400. By observing whether the pressure values ​​applied to the first side 101 and the second side 102 are consistent or exceed the target value range, the clamping plates of the welding fixture can be adjusted, and ultimately the pressures applied to the first side 101 and the second side 102 of the battery contoured body 100 are consistent or very close. After the welding fixture is adjusted, the auxiliary standard block is removed and the battery to be welded is placed in the welding fixture. At this time, the pressures on all sides of the battery to be welded are consistent, and the amplitude of the battery's rebound after being compressed is also consistent. Ultimately, the height of the upper reference surface of the battery (the side of the battery facing away from the welding fixture along the Z direction, which is also the welding surface of the battery) is consistent, thereby effectively improving the welding quality rate during welding.

[0039] The detection end face of the first pressure sensor 200 and the corresponding first side face 101 are designed as the same plane, and the detection end face of the second pressure sensor 300 and the corresponding second side face 102 are designed as the same plane, so that the pressure received by the first pressure sensor 200 is highly consistent with the pressure received by the first side face 101, and the pressure received by the second pressure sensor 300 is highly consistent with the pressure received by the second side face 102, thereby improving the pressure detection accuracy.

[0040] The first pressure sensor 200 and the second pressure sensor 300 in the embodiment are high-precision pressure sensors, and through the connection with the display 400, the pressure value can be visualized, and the edge adjustment welding fixture can be realized.

[0041] The target value range of the pressure can be determined according to the actual situation, and details are not repeated.

[0042] Further, the first pressure sensor 200 is installed at the center of one of the first side faces 101, and the second pressure sensor 300 is installed at the center of one of the second side faces 102.

[0043] When the clamping plate of the welding fixture is tightly attached to the side face of the battery profiling body 100, the center position of the corresponding side face is more stable under stress, and the pressure value received by the side face can better represent the pressure value of the entire side face. Therefore, the first pressure sensor 200 is installed at the center of the first side face 101, and the second pressure sensor 300 is installed at the center of the second side face 102, which can further improve the pressure detection accuracy and facilitate accurate adjustment of the welding fixture.

[0044] Of course, in other embodiments, with reference to Figure 1 Since the area of the second side face 102 is smaller, the second pressure sensor 300 can also be installed at a position deviating from the center of the second side face 102, which has less effect on the detection accuracy of the second pressure sensor 300.

[0045] Further, the first side face 101 corresponding to the first pressure sensor 200 is provided with a first installation slot 110, the first installation slot 110 has a first opening facing the X direction and a second opening facing the Z direction, the first pressure sensor 200 is installed in the first installation slot 110, the detection end face of the first pressure sensor 200 faces the first opening, and the first pressure sensor 200 is connected with the display 400 through the first lead wire passing through the second opening;

[0046] A second mounting groove 120 is defined on the second side surface 102 corresponding to the second pressure sensor 300. The second mounting groove 120 has a third opening facing the Y direction and a fourth opening facing the Z direction. The second pressure sensor 300 is mounted in the second mounting groove 120, with the detection end face of the second pressure sensor 300 facing the third opening. The second pressure sensor 300 is connected to the display 400 via a second wire passing through the fourth opening. The X direction, Y direction, and Z direction are perpendicular to each other.

[0047] In this embodiment, the first wire connected to the first pressure sensor 200 can be led out from the second opening and connected to the display 400, and the second wire connected to the second pressure sensor 300 can be led out from the fourth opening and connected to the display 400. This structural design facilitates the layout of the corresponding wires.

[0048] Furthermore, if Figures 1 to 3 As shown, the first mounting groove 110 includes a first main groove 111 and a first avoidance groove 112 that are connected to each other. The first avoidance groove 112 is located on a side of the first main groove 111 that is away from the welding fixture along the Z direction. The first pressure sensor 200 is fixed in the first main groove 111 by bolts. The first wire is located in the first avoidance groove 112. The first main groove 111 has a first opening, and the first avoidance groove 112 has a second opening.

[0049] like Figure 1 、 Figure 2 and Figure 4 As shown, the second mounting groove 120 includes a second main groove 121 and a second avoidance groove 122 that are connected to each other. The second avoidance groove 122 is located on the side of the second main groove 121 away from the welding fixture along the Z direction. The second pressure sensor 300 is fixed in the second main groove 121 by bolts. The second wire is located in the second avoidance groove 122. The second main groove 121 has a third opening, and the first avoidance groove 112 has a fourth opening.

[0050] Among them, the length of the first main groove 111 and the length of the second main groove 121 extend along the Z direction respectively, which is convenient for arranging the first wire and the second wire, avoiding the protrusion of the wire affecting the pressing of the welding fixture on the battery contour 100, and at the same time making the length of the first main groove 111 and the second main groove 121 shorter, saving wires, and improving the processing efficiency of the auxiliary standard block.

[0051] For example, the first pressure sensor 200 and the second pressure sensor 300 are both cylindrical structures. Therefore, in this embodiment, the first main groove 111 is designed to have a corresponding circular structure, that is, the shape of the first pressure sensor 200 and the first main groove 111 match each other. The bottom of the first main groove 111 is provided with four threaded holes that penetrate the battery shaped body 100 along the X direction. The first pressure sensor 200 is also provided with connecting holes corresponding to the threaded holes. Bolts pass through the connecting holes and are screwed and fixed to the threaded holes, thereby fixing the first pressure sensor 200 in the first main groove 111. Of course, the pressure sensor is not limited to being fixed directly in the corresponding main groove by screws. Figure 1 and Figure 2 As shown, the second pressure sensor 300 is fixed to the backing plate 500 by bolts, and the backing plate 500 is fixedly connected to the second main groove 121 by bolts, which can also achieve the installation and fixation of the second pressure sensor 300.

[0052] Furthermore, the first avoidance groove 112 has a first opening in the same direction as the first opening, the first opening communicating with the first opening and the second opening, and the second avoidance groove 122 has a second opening in the same direction as the third opening, the second opening communicating with the third opening and the fourth opening.

[0053] When the clamping plate of the welding fixture facing the first side 101 presses against the first side 101, a certain amount of airflow resistance is generated. By providing the first opening, the airflow can enter the first avoidance groove 112 through the first opening and be directed out through the second opening, thereby preventing the airflow from being trapped between the first side 101 and the corresponding clamping plate, which could cause distortion in the detection data of the corresponding first pressure sensor 200. Similarly, when the clamping plate of the welding fixture facing the second side 102 presses against the second side 102, a certain amount of airflow resistance is also generated. By providing the second opening, the airflow can enter the second avoidance groove 122 through the second opening and be directed out through the fourth opening, thereby preventing the airflow from being trapped between the second side 102 and the corresponding clamping plate, which could cause distortion in the detection data of the corresponding second pressure sensor 300.

[0054] Furthermore, the second main groove 121 extends through the battery contour 100 at both ends along the X-direction. Because the second side surface 102 is relatively narrow along the X-direction, this embodiment designates the second main groove 121 to extend through the battery contour 100 at both ends along the X-direction to facilitate machining of the battery contour 100. Furthermore, the airflow generated when the welding fixture compresses the second side surface 102 can be quickly discharged through the second main groove 121 at both ends along the X-direction.

[0055] Furthermore, the battery-shaped body 100 is penetrated by a plurality of through-hole structures 130 along the X-direction. Because the first side 101 has a larger area, the airflow resistance generated when the clamping plate presses against the first side 101 is perpendicular to the first side 101 (along the X-direction). Therefore, by providing a plurality of through-hole structures 130 penetrating the battery-shaped body 100, a portion of the airflow can be quickly introduced into the through-hole structures 130.

[0056] Furthermore, the through-hole structure 130 includes a plurality of first through-holes 131 and a plurality of second through-holes 132. The first through-holes 131 and the second through-holes 132 are symmetrical with respect to at least one centerline of the battery shaped body 100. The length of the centerline extends along the Y direction or along the Z direction, and the X direction, Y direction, and Z direction are perpendicular to each other. By symmetrically arranging the first through-holes 131 and the second through-holes 132, the airflow on both sides of the centerline can be synchronously introduced into the corresponding through-hole structure 130, thereby preventing the battery shaped body 100 from tilting when the clamping plate of the welding fixture along the X direction is pressed against the battery shaped body 100, thereby preventing the detection accuracy of the first pressure sensor 200 from being affected. For example, as Figure 3 As shown, the first through hole 131 and the second through hole 132 are symmetrical with respect to two center lines, wherein the length of one center line extends along the Y direction, and the length of the other center line extends along the Z direction.

[0057] Furthermore, in order to more intuitively observe the pressure value detected by each pressure sensor, this embodiment provides a display 400 for each pressure sensor. The display 400 includes a first display 410 connected to the first pressure sensor 200 and a second display 420 connected to the second pressure sensor 300. The first display 410 and the second display 420 are mounted on a side of the battery contour body 100 facing away from the welding fixture along the Z direction. The first display 410 and the second display 420 are spaced apart along the Y direction, with the first display 410 adjacent to the first pressure sensor 200 and the second display 420 adjacent to the second pressure sensor 300.

[0058] In this embodiment, the auxiliary standard block for adjusting the welding fixture further includes a mounting bracket 600, such as Figure 1 、 Figure 2 and Figure 5 As shown, the mounting bracket 600 is fixed to one side of the battery contoured body 100 away from the welding fixture along the Z direction, the first display 410 and the second display 420 are mounted on the mounting bracket 600, and the mounting bracket 600 has a first avoidance opening 601 for the first wire connecting the first display 410 and the first pressure sensor 200 to pass through, and a second avoidance opening 602 for the second wire connecting the second display 420 and the second pressure sensor 300 to pass through.

[0059] Because the display 400 is relatively tall, this embodiment employs a box-shaped mounting frame 600, with the first and second displays 410, 420 embedded within the mounting frame 600. The display screens of the first and second displays 410, 420 are exposed outside the mounting frame 600, facilitating observation of test data. The first and second escape openings 601, 602 facilitate the routing of wires, minimizing their length.

[0060] Illustratively, the mounting frame 600 includes a mounting frame body 610 in a box structure and two ear plates 620 . The two ear plates 620 are respectively connected to both sides of the mounting frame body 610 along the Y direction, and the two ear plates 620 are respectively fixed to the battery contour body 100 by screws. Specifically, a first mounting hole 603 and a second mounting hole 604 are provided at intervals on one side of the mounting frame body 610 facing the battery shaped body 100. The first display 410 is installed in the first mounting hole 603 adjacent to the first pressure sensor 200, and the second display 420 is installed in the second mounting hole 604 adjacent to the second pressure sensor 300. The first avoidance opening 601 is the opening portion of the mounting frame body 610 of the box structure. The first avoidance opening 601 covers the second opening. Therefore, the first wire can directly pass through the second opening and extend into the mounting frame body 610 to connect with the first display 410; a second avoidance opening 602 is provided on the side of the mounting frame body 610 close to the second pressure sensor 300 along the Y direction. The second wire connected to the second pressure sensor 300 passes through the fourth opening and the second avoidance opening 602 in sequence to connect with the corresponding second display 420.

[0061] like Figure 6 As shown, the existing welding fixture 1 has two welding positions, which means that two batteries 2 can be welded simultaneously at a time. Accordingly, when adjusting the dimensions of the two welding positions, two auxiliary standard blocks are required to assist in adjusting the welding fixture 1. After adjustment, the two batteries 2 can be placed in each welding position.
