Description

Technical Field

[0001] The utility model belongs to the technical field of welding aids and relates to a capacitor welding jig. Background Technique

[0002] A capacitor (i.e., a condenser) generally consists of two conductors close to each other with a layer of non-conductive insulating medium in between. When a voltage is applied between the two plates of the capacitor, the capacitor will store electric charges. The capacitance of the capacitor is numerically equal to the ratio of the electric charge quantity on one conductive plate to the voltage between the two plates. Capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering.

[0003] For capacitors, after spraying a conductive layer on the capacitor, conductive electrodes need to be welded to both poles. Currently, the work of welding conductive electrodes usually relies on manual operation: workers hold the capacitor by hand and then position the conductive electrode at the conductive end of the capacitor; this results in difficult positioning, great welding difficulty, and is prone to causing injuries to workers.

[0004] The Chinese utility model patent with the application number 201820192204.3 discloses a welding jig for thin-film capacitor copper electrodes, which includes a first base, a vertical rod, and a second base; the second base includes a second vertical bottom plate and two third vertical plates respectively connected to the left and right ends of the second vertical bottom plate, and the openings of the first base and the second base do not cross; the bottom end of the vertical rod is connected to the outer side wall of the first vertical plate, and the top end is connected to the inner bottom surface of the second vertical bottom plate; at least two limiting shafts pass through the vertical rod and are respectively connected to the inner walls of the two third vertical plates. This welding jig for thin-film capacitor copper electrodes is provided with a first base for limiting the thin-film capacitor core and a second base for limiting the copper electrodes, so that the end of the copper electrode just contacts the electrode position of the thin-film capacitor core. During welding, there is no need to hold the thin-film capacitor core and the copper electrode by hand, the electrode positioning is accurate, the welding is easy, the welding efficiency is improved, and the injury rate caused by welding is reduced. However, the structure of this welding jig is relatively simple and the function is single, and it cannot be used in cooperation with automated equipment. Summary of the Invention

Similar elements in different embodiments are denoted by related similar element numbers.

[0026] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean that they are essential components and / or sequences.

[0027] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described, and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0028] Such as Figure 1 and Figure 2The shown capacitor electrode sleeve 1' is used to connect two capacitors 2' together (stacked together), and includes a sleeve body 11' with one end open, an end plate 12' integrally formed 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 pole columns 13' installed on the outer surface of the end plate 12' and extending in a direction away from the sleeve body 11' (the two pole columns 13' are preferably centrosymmetric about the center of the end plate 12'), a first electrode sheet 15' installed on the inner surface of the end plate 12' and connected to one pole column 13' in the middle (both ends of the first electrode sheet 15' extend along the inner wall of the sleeve body 11' to the outside of the opening of the sleeve body 11'), and a second electrode sheet 14' installed on the inner surface of the end plate 12' and connected to the other pole column 13' at the end (only one end (defined as the outer end) of the second electrode sheet 14' extends along the inner wall of the sleeve body 11' to the outside of the opening of the sleeve body 11', but the length of this end extending out of the sleeve body 11' is greater than the length of any end of the aforementioned first electrode sheet 15' extending out of the sleeve body 11'). Two avoidance holes 121' are symmetrically arranged on the end plate 12' to expose the second electrode sheet 14' (mainly expose the other end of the second electrode sheet 14') and the placed capacitor 2' (expose a partial area of the end face of the capacitor 2').

[0029] 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 one end (one of the two ends) of the first electrode sheet 15' so that it contacts and is welded and fixed to the other end face of the first capacitor 2'; bend the other end of the first electrode sheet 15' so that it contacts and is welded and fixed to the end face of the second capacitor 2'. 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' so that it contacts and is welded and fixed to the other end face of the second capacitor 2'. In this way, the two capacitors 2' and the capacitor electrode sleeve 1' are combined together, realizing the parallel connection of the two capacitors 2'.

[0030] As Figures 3 to 6 The shown capacitor welding fixture 1 is almost applicable to the welding of all circular capacitors (with wide applicability), and 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' on the corresponding end faces of the capacitor 2'. It includes a bearing mechanism 11, a first pressing mechanism 12, a side-lying mechanism 13, a second pressing mechanism 14, a third pressing mechanism 15, etc.

[0031] Among them, the carrying mechanism 11 at least includes a carrying plate 111 and a first limiting unit and a second limiting unit arranged on one surface of the carrying plate 111 (either surface can be selected, and other mechanisms are also installed on this surface); the first limiting unit at least includes a first base 114 arranged on one surface of the carrying plate 111 and a first limiting seat 115 arranged on the first base 114; the second limiting unit at least includes a second base 116 arranged on one surface of the carrying plate 111 and on one side of the first base 114 and a second limiting seat 117 arranged on the second base 116. During 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 first limiting seat 115 (manually).

[0032] The first pressing mechanism 12 is installed on one surface of the carrying plate 111 and cooperates with the first limiting seat 115 to press one end of the aforementioned first electrode piece 15' against the other end surface of the first capacitor 2' (to cooperate with the welding machine for welding).

[0033] The side-lying mechanism 13 is installed on one surface of the carrying plate 111 and cooperates with the second limiting seat 117. The second pressing mechanism 14 is also installed on one surface of the carrying plate 111 and cooperates with the second limiting seat 117. (Manually) transfer the first combination (after welding) to the side-lying mechanism 13, place a second capacitor 2' into the second limiting seat 117, operate the second pressing mechanism 14 to press the other end of the first electrode piece 15' against the end surface of the second capacitor 2' (to cooperate with the welding machine for welding), and then (manually) stack the first capacitor 2' on the second capacitor 2' (at this time, the second combination is obtained).

[0034] The third pressing mechanism 15 is installed on one surface of the carrying plate 111 and cooperates with the first limiting seat 115. (Manually) flip the second combination (combining two capacitors 2') by 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 piece 14' against the other end surface of the second capacitor 2'. It can be seen that in this way, the limiting and clamping of capacitors 2' in different states can be realized, so as to cooperate with the welding machine to realize the electrode connection of two capacitors 2', improving the welding efficiency.

[0035] In this embodiment, the carrying mechanism 11 further includes two handles 112 and two quick-change spring clips 113 installed on one surface of the carrying plate 111 and 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 inward from its outer end face, and the second limiting seat 117 is provided with at least one notch 1171 extending inward from its outer end face; this can facilitate the operation of workers and improve efficiency.

[0036] The first limiting seat 115 further has a first through hole 1152 opened at the center of its inner bottom surface, first limiting holes 1153 arranged on its inner bottom surface and on both sides of the first through hole 1152, and first limiting protrusions 1154 arranged on its inner bottom surface and 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 further has a second through hole 1172 opened at the center of its inner bottom surface. This can achieve the positioning of the capacitor electrode sleeve 1', and avoid relative rotation during welding.

[0037] The side-lying mechanism 13 includes a plurality of support members 131 erected on one surface of the carrier plate 111 and on one side of the second limiting unit, a side-lying seat 132 installed on the tops of the plurality of support members 131 and provided with a limiting trough 134, and a limiting baffle 133 fixed on the side surface of the side-lying seat 132 and cooperating with the limiting trough 134. This can achieve the limiting of the aforementioned first combination, thereby improving the precision of the cooperation. The side-lying mechanism 13 further includes an arc-shaped groove 135 opened in the side-lying seat 132 and communicating with the limiting trough 134 to reduce friction and facilitate operation.

[0038] 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 aforementioned functions. For example, the first pressing mechanism 12 includes a first support rod 121 and a first chuck 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 chuck 142 installed on the top of the second support rod 141.
