[0032] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0033] like Figure 1 and Figure 2 The capacitor electrode sleeve 1' shown is used to connect two capacitors 2' to be combined together (stacked together), including a sleeve body 11' with an opening at one end, an end plate 12' formed integrally at the other end of the sleeve body 11' (the sleeve body 11' and the end plate 12' are preferably made of insulating materials), two poles 13' installed on the outer surface of the end plate 12' and extending in a direction away from the sleeve body 11' (the two poles 13' are preferably symmetrical about the center of the end plate 12'), and a first electrode sheet 15' installed on the inner surface of the end plate 12' and connected to one pole 13' in the middle (both ends of the first electrode sheet 15' extend along the inner wall of the sleeve body 11' to the sleeve The end plate 12' is provided with two symmetrically arranged avoidance holes 121' to expose the second electrode sheet 14' (mainly exposing the other end of the second electrode sheet 14') and the inserted capacitor 2' (exposing a part of the end surface of the capacitor 2').

[0034] During welding, first place the first capacitor 2' into the capacitor electrode sleeve 1' (the depth of the capacitor electrode sleeve 1' is preferably less than the height of the capacitor 2'), so that the end face of the first capacitor 2' contacts the first electrode sheet 15' and the second electrode sheet 14', bend any end (one of the two ends) of the first electrode sheet 15' to contact the other end face of the first capacitor 2' and weld it; bend the other end of the first electrode sheet 15' to contact the end face of the second capacitor 2' and weld it, stack the second capacitor 2' and the first capacitor 2' together, at this time, the end face of the second capacitor 2' contacts the other end face of the aforementioned first capacitor 2'; bend the outer end of the second electrode sheet 14' to contact the other end face of the second capacitor 2' and weld it. In this way, the two capacitors 2' and the capacitor electrode sleeve 1' are combined together, and the parallel connection of the two capacitors 2' is realized. This is because the power capacitor is composed of multiple capacitors 2' in parallel, and to achieve parallel connection, it is necessary to weld the capacitors 2' together with copper plates (electrode sheets). The welding fixture 1 described below realizes automatic welding of the capacitor 2' and the copper plate by positioning the capacitor 2' and the copper plate.

[0035] At present, in the power capacitor industry, the welding of this product (power capacitor) is almost all done manually. Welding requires very high labor costs and the welding efficiency is very low. The welding fumes are also very harmful to the human body.

[0036] The double-station capacitor soldering machine of the present invention is as follows: Figure 3 As shown, it mainly includes a welding fixture 1, a supporting assembly 2, a fixture moving assembly 3 and a lifting welding assembly 5, etc.

[0037] Among them, the support assembly 2 includes an operating table 21 and a support frame 22 erected on the operating table 21. There are multiple groups of welding fixtures 1 (two groups in this embodiment), which are arranged at intervals. There are also multiple groups of fixture moving assemblies 3 (also two groups in this embodiment), which are installed on the operating table 21; multiple groups of welding fixtures 1 are installed on multiple groups of fixture moving assemblies 3 one by one, so that the fixture moving assemblies 3 drive the corresponding welding fixtures 1 to move back and forth in a straight line; the two groups of fixture moving assemblies 3 work asynchronously to cooperate with manual continuous operation. There are also multiple groups of lifting welding assemblies 5, which are movably installed on the support frame 22 through the corresponding group of welding moving assemblies 6 to cooperate with the welding fixture 1; when the lifting welding assembly 5 is driven by the welding moving assembly 6 to the corresponding welding fixture 1, it performs a descending action to move to a suitable position for welding, and rises and resets after welding is completed. The welding fixture 1 of the present application is installed on the fixture moving component 3, and the manual worker can quickly place the product and the copper plate into the solder fixture 1 for positioning. The solder fixture 1 moves to a fixed position for automatic welding, and the manual worker only needs to continuously clamp and position, and the efficiency is very high.

[0038] In this embodiment, the double-station capacitor soldering machine also includes a plurality of cleaning modules 8 (each cleaning module 8 has an air blowing cleaning unit and a brush cleaning unit) installed on the operating table 21 and corresponding to the welding fixture 1. After the reset, the lifting welding assembly 5 also moves to the cleaning module 8 so that the cleaning module 8 performs air blowing and brush cleaning on it respectively. The double-station capacitor soldering machine also includes a smoking module 4 installed on the support frame 22 and corresponding to the welding fixture 1, and an outer cover (not shown) installed on the operating table 21 for covering other structures. The welding position is at a safe distance from people to prevent the harm of solder smoke to the human body.

[0039] In this embodiment, the fixture moving assembly 3 includes a first linear slide, a first drive motor connected to the first linear slide to drive the first linear slide, and a limit unit installed on the first linear slide for fixing or clamping the welding fixture 1 (the limit unit can be conventional, as long as it can fix or clamp the welding fixture 1, such as including a base plate and a buckle installed on the base plate and matched with the quick-change spring clip 113). The welding moving assembly 6 includes a second linear slide, a second drive motor connected to the second linear slide to drive the first linear slide, and an adapter plate installed on the second linear slide for installing the lifting welding assembly 5.

[0040] Lifting welding assembly 5, such as Figure 4 As shown, it includes a carrier 51 installed on the adapter plate, a lifting mechanism 52 installed on the carrier 51, a base 53 installed at the bottom end of the lifting mechanism 52, and a solder gun 54 installed on the base 53; the lifting mechanism 52 adopts the existing conventional one as long as it can achieve accurate lifting and lowering of the solder gun 54.

[0041] like Figures 5 and 6 The capacitor welding fixture 1 shown (the welding fixture 1 has a wide range of applicability and is suitable for almost all circular capacitor welding) is used to accommodate and place the capacitor electrode sleeve 1' and the capacitor 2', and press the first electrode sheet 15' and the second electrode sheet 14' onto the corresponding end faces of the capacitor 2'. It includes a supporting mechanism 11, a first pressing mechanism 12, a side-lying mechanism 13, a second pressing mechanism 14 and a third pressing mechanism 15, etc.

[0042] The bearing mechanism 11 at least comprises a bearing plate 111 and a first limiting unit and a second limiting unit arranged on a surface of the bearing plate 111 (any surface can be selected, and other mechanisms are also installed on the surface); the first limiting unit at least comprises a first base 114 arranged on a surface of the bearing plate 111 and a first limiting seat 115 arranged on the first base 114; the second limiting unit at least comprises a second base 116 arranged on a surface of the bearing plate 111 and located on one side of the first base 114 and a second limiting seat 117 arranged on the second base 116. When in use, first (manually) place a capacitor 2' into the capacitor electrode sleeve 1', and then place their combination (defined as the first combination) into the (manual) first limiting seat 115.

[0043] The first pressing mechanism 12 is mounted on a surface of the carrier plate 111 and cooperates with the first limiting seat 115 to press one end of the first electrode sheet 15 ′ onto the other end surface of the first capacitor 2 ′ (to cooperate with a welding machine for welding).

[0044] The side-lying mechanism 13 is installed on a surface of the carrier plate 111 and cooperates with the second limit seat 117. The second pressing mechanism 14 is also installed on a surface of the carrier plate 111 and cooperates with the second limit seat 117. The first assembly (after welding) is transferred to the side-lying mechanism 13 (manually), the second capacitor 2' is placed in the second limit seat 117, the second pressing mechanism 14 is operated to press the other end of the first electrode sheet 15' on the end face of the second capacitor 2' (to cooperate with the welding machine for welding), and then the first capacitor 2' is stacked on the second capacitor 2' (at this time, the second assembly is obtained).

[0045] The third pressing mechanism 15 is installed on a surface of the carrier plate 111 and cooperates with the first limiting seat 115. (Manually) flip the second assembly (combining two capacitors 2') 180° so that the second capacitor 2' is on the top; operate the third pressing mechanism 15 to press the outer end of the second electrode sheet 14' on the other end surface of the second capacitor 2'. It can be seen that this can achieve the limiting and clamping of capacitors 2' in different states, thereby cooperating with the welding machine to achieve the electrode connection of the two capacitors 2', and improve the welding efficiency.

[0046] In this embodiment, the supporting mechanism 11 also includes two handles 112 and two quick-change spring clips 113 installed on a surface of the supporting plate 111 and located on both sides of the first limiting unit and the second limiting unit; that is, the first limiting unit and the second limiting unit are located between the two handles 112 and also between the two quick-change spring clips 113; the first limiting seat 115 is provided with a pair of notches 1151 extending inwardly from its outer end surface, and the second limiting seat 117 is provided with at least one notch 1171 extending inwardly from its outer end surface; this can facilitate the operation of workers and improve efficiency.

[0047] The first limiting seat 115 also has a first through hole 1152 opened at the center of its inner bottom surface, a first limiting hole 1153 set on its inner bottom surface and located on both sides of the first through hole 1152, and a first limiting protrusion 1154 set on its inner bottom surface and located on both sides of the first through hole 1152 (the two first limiting holes 1153 and the two first limiting protrusions 1154 are symmetrical about the first through hole 1152); the second limiting seat 117 also has a second through hole 1172 opened at the center of its inner bottom surface. In this way, the capacitor electrode sleeve 1' can be positioned to prevent it from rotating relative to the electrode sleeve during welding.

[0048] The side-lying mechanism 13 includes a plurality of supporting members 131 erected on a surface of the bearing plate 111 and located on one side of the second limiting unit, a side-lying seat 132 installed on the top of the plurality of supporting members 131 and provided with a limiting groove 134, and a limiting baffle 133 fixed on the side of the side-lying seat 132 and matched with the limiting groove 134, so that the limiting of the aforementioned first combination can be achieved, thereby improving the precision of the matching. The side-lying mechanism 13 also includes an arc groove 135 provided in the side-lying seat 132 and communicating with the limiting groove 134 to reduce friction and facilitate operation.

[0049] In addition, the first pressing mechanism 12 and the second pressing mechanism 14 can adopt existing conventional structures as long as they can achieve the above functions. For example, the first pressing mechanism 12 includes a first support rod 121 and a first clamp 122 installed on the top of the first support rod 121, and the second pressing mechanism 14 includes a second support rod 141 and a second clamp 142 installed on the top of the second support rod 141.

The third short swing arm is pivotally connected to the seat 1522 and is spaced apart from the third long swing arm 1523, and the lever 1527 is pivotally connected to the third long swing arm 1523 and the third short swing arm (the end of the lever 1527 is pivotally connected to the third long swing arm 1523, and the relatively inner side of the end is pivotally connected to the third short swing arm, and the pivot connection between the third long swing arm 1523 and the lever 1527 and the pivot connection between the third long swing arm 1523 and the third mounting seat 1522 are arranged front and back, as shown in FIG.
