Background

The method of delivering electricity using copper materials as a conductive medium is widely used in the electrical field, as is the case in the production of large quantities of consumer goods such as new energy automobiles, household appliances, and the like. In the case of high-current supply locally within the device, bus bars can be used for power supply, as is common in battery-operated circuits. In order to achieve wiring, the wires need to be bent with a specific track to avoid other mechanisms, and therefore, besides good conduction of the wires, certain flexibility or plasticity is required to be set according to a certain track during wiring. The solution is to use copper bars stacked with copper sheets. Because the copper sheets are stacked, the bending of the copper sheets can be realized conveniently, and the damage of the internal structure can not occur under the bending of a large angle. As shown in fig. 1, the copper bar is formed by stacking a plurality of copper sheets, and the copper sheets are generally formed into a whole by using polymer welding at both ends of the copper sheets, are not welded in the middle, and may be preformed into a certain shape to extend along a predetermined track after being mounted and avoid a surrounding structure.

In the welding process of copper sheets, the position between stacked copper sheets needs to be ensured to be accurate, dislocation cannot occur during welding, and particularly, under the condition that one end of the copper sheets is welded well and shaped, the shape of the copper sheets can be bent, and the copper sheets are inconvenient to take and fix. In addition, the scheme of welding the handheld copper sheet cannot be practically used because high temperature is often accompanied in the process of welding the copper sheet.

Detailed Description

The present utility model will be described in detail below with reference to the drawings and the specific embodiments, and in the present specification, the dimensional proportion of the drawings does not represent the actual dimensional proportion, but only represents the relative positional relationship and connection relationship between the components, and the components with the same names or the same reference numerals represent similar or identical structures, and are limited to the schematic purposes.

Fig. 1 is a schematic view of a copper bar W. The copper bar W is formed by accurately stacking a plurality of copper sheets X, and in order to form a compact whole among the copper sheets X, the copper sheets X are formed into a whole at the first end W1 and the second end W2 of the copper bar W through processes such as polymer diffusion welding and the like, so that the two ends of the copper bar W are conveniently fixed with terminals of equipment. Measures are needed in the welding process to ensure that the X edges of the copper sheets can be aligned. The connecting section WB for connecting the first end W1 and the second end W2 may be linear, or may be pre-bent or pre-bent into a specific shape, so as to meet different installation environment requirements. And the bending or bending process is often completed between two welding processes, one end of the copper sheet is fixed, and the alignment problem of the copper sheet X is not needed to be considered in the bending process. On the other hand, in order to ensure that the two ends of the bent copper bar W can still be aligned, the size of the copper sheet X is designed to have slightly different lengths along with the different layers of the copper sheet X. After the bending is completed, the copper bar W does not keep the original plane shape, but has a specific curve or broken line shape, and the problem of how to realize stable clamping and accurate positioning of the copper bar W, thereby ensuring secondary welding is also a problem in the prior art.

The utility model aims to provide a clamp for welding the copper sheet X. Fig. 2 is a schematic structural view of the copper sheet welding fixture, and please refer to a partial schematic view of fig. 3. The fixture 1 comprises a first pressing die 11, and a limiting groove 11W for limiting the copper sheet X is formed in the first pressing die 11. The fixture 1 further comprises a second pressing die 12 which is arranged in a moving manner relative to the first pressing die 11, and a pressing block 121 for pressing the copper sheet X in the limit groove 11W is arranged on the second pressing die 12. The plurality of copper sheets X are aligned in the limiting groove 11W in a limiting way by the limiting groove 11W, the compressing block 121 compresses the copper sheets X from the opening of the limiting groove 11W to ensure that the copper sheets X are stable and free from moving in the limiting groove 11W, so that the stacked layers of copper sheets X can be aligned well when being welded at the first end W1 or the second end W2.

Preferably, the first press die 11 has a first press surface 112 which is shaped to curve the copper bar W, and the second press die 12 has a second press surface 122 which is shaped to curve the copper bar W corresponding to the first press surface 112. Therefore, after the first welding is completed, when the copper bar W has been bent into a preset shape, the connection section WB of the copper bar W may be disposed between the first compression surface 112 and the second compression surface 122, and the copper sheet X may be positioned more accurately and reliably by the first compression surface 112, the second compression surface 122, the limiting groove 11W and the compression block 121. In addition, in a more general case, after one end of the copper bar W has been welded, the unbent copper bar W may be directly placed between the first die 11 and the second die 12, and the copper bar W may be pre-bent into a predetermined shape while the second die 12 is moved and advanced, and at the end, the copper bar W may be naturally press-fastened between the first die 11 and the second die 12 as described above. This is equivalent to the pre-bending process of the copper bar W being completed while the copper bar W is being pressed on the present copper sheet welding jig.

Preferably, a support plate 13 is provided at one side of the first stamper 11 where the copper bar W is exposed, and the support plate 13 is provided below a portion of the copper bar W extending outside the first stamper 11 to support the copper bar W from falling. As shown in fig. 1 or 3, the copper sheet X has a shape with a large end area and a small end area, which may cause the center of gravity of the copper bar W to be located at the end with a large area during welding, and may also be the end of the copper bar W extending out of the first press mold 11, when the support plate 13 is not provided, the copper bar W may be turned over and fall out due to the center of gravity outside the first press mold 11 at the moment when the second press mold 12 is not yet clamped, and the support plate 13 supports the copper bar W. Preferably, the copper bar W is rotatably arranged around one end pivot 131, so that after the copper bar W is clamped, the copper bar W is rotated out of the supporting position, and the clamp 1 can conveniently perform subsequent actions.

The utility model also provides a copper sheet welding feeding and discharging device which is used for welding feeding and discharging of the copper bar W. Fig. 4 is a schematic structural view of a copper sheet welding loading and unloading device. The copper sheet welding feeding and discharging device comprises a rack 2 which is close to the working surface of the welding equipment, a sliding seat 21 is arranged on the rack 2 in a moving mode, a clamp 1 is arranged on the sliding seat 21, then the clamp 1 can be far away from or close to the welding equipment on the rack 2, feeding and discharging operations are convenient to conduct when the clamp is far away from the rack, and when the clamp is close to the rack, copper bars W extend into graphite electrodes of the welding equipment to finish polymer diffusion welding. Preferably, the fixture 1 is slidably arranged on the sliding seat 21, such as the scheme of adjusting the corresponding position of the fixture 1 on the sliding rail of the sliding seat 21 through the hand wheel shown in fig. 4, which is mainly convenient for adjusting the height of the fixture 1, so that the copper bar W is ensured to be highly accurate when entering between graphite electrodes, and the problem that the copper bar W is deformed and scrapped due to collision with the electrodes and is deformed when being welded due to overlarge height difference between the copper bar W and the electrodes after entering between the electrodes is avoided. In addition, the frame 2 is preferably provided with a blanking port 2W along the moving path of the jig 1, and as described above, the copper bar W automatically drops when the jig 1 is not clamped any more due to the gravity center problem. When the welding is completed, the clamp 1 exits from the welding position to reach the position above the blanking port 2W, the second pressing die 12 is loosened, and the copper bar W falls into a cooling groove arranged below from the blanking port 2W, so that automatic material receiving is completed.

The foregoing is merely illustrative of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and various modifications and improvements made by those skilled in the art to which the utility model pertains will fall within the scope of the utility model as defined by the appended claims without departing from the spirit of the utility model.
