It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, a welding fixture 100 for a resonant column according to a preferred embodiment of the present invention includes a base 110, a support plate 120 and a pressing plate 130.

Referring to fig. 2, the base 110 serves to support and fix the resonant columns 101 to be welded. The base 110 is generally formed by metal casting. The base 110 has a plurality of fixing grooves 111 formed at intervals on its surface. The resonant column 101 can be held in the fixing groove 111 to fix the resonant column, so the shape and size of the inner wall of the fixing groove 111 should match the outer contour of the resonant column 101. Under the limiting action of the fixing groove 111, the resonant column 101 can be kept stable in the transferring and welding processes.

In the present embodiment, the base 110 has a long bar shape, and the plurality of fixing grooves 111 are spaced apart along the length direction of the base 110. Therefore, the resonant columns 101 are also linearly spaced apart from each other when they are fixed to the base 110, thereby preventing interference between the plurality of resonant columns 101 during welding.

Referring to fig. 3, the support plate 120 is mounted on the base 110 and has a holding surface 121. The support plate 120 is used to cooperate with the pressure plate 130 to hold the wires 102 to be soldered.

The platen 130 has a mating surface (not shown) that is one surface of the platen 130. Furthermore, the pressing plate 130 is detachably mounted on the base 110 and makes the mating surface fit with the holding surface 121. Further, at least one of the mating surface and the holding surface 121 is formed with a plurality of bar-shaped grooves 123, so that a plurality of wire clamp grooves (not shown) are formed between the mating surface and the holding surface 121. The wire clamping groove is a channel structure formed between the support plate 120 and the pressing plate 130, and the matching surface and the clamping surface 121 are inner walls. In the present embodiment, the strip-shaped groove 123 is formed on the support plate 120.

When the lead 102 is fixed, the support plate 120 is separated from the pressing plate 130, the lead 102 is placed in the strip-shaped groove 123, and finally the matching surface and the clamping surface 121 are attached again, so that the lead 102 can be clamped in the wire clamping groove. Under the limiting action of the wire clamping groove, the lead 102 can be kept stable in the transferring and welding processes.

In this embodiment, the brace 120 is removably mounted to the base 110. Therefore, when the lead 102 is installed, the support plate 120 and the pressing plate 130 can be detached from the base 110, and then the lead 102 can be fixed and then installed on the base 110 again. Thus, a space limitation due to the presence of the base 110 is avoided, thereby making the operation more convenient.

Further, in the present embodiment, the support plate 120 includes a plate body 122 and support legs 124 at two ends of the plate body 122. The two ends of the surface of the base 110 are further provided with positioning grooves 113, and the support legs 124 are inserted into the positioning grooves 113 to mount the support plate 120 on the base 110.

Specifically, the support plate 120 can be straddled on the surface of the base 110 by the support legs 124 at the two ends, which is beneficial to improving the overall compactness of the resonant column welding fixture 100. Moreover, the support plate 120 can be quickly disassembled and assembled by pulling and inserting the support legs 124, and the convenience of operation is further improved.

The plurality of wire clamping grooves correspond to the plurality of fixing grooves 111 one to one, and one end of each wire clamping groove points to the corresponding fixing groove 111. As shown, the base 110 has 4 fixing slots 111, so that 4 wire clip slots are formed between the support plate 120 and the pressing plate 130.

Since one end of the clip slot is directed to the corresponding fixing slot 111, the conductive wire 102 in the clip slot can be extended to the surface of the corresponding resonant post 101 by selecting a suitable length. Further, the entire resonance post welding fixture 100 is placed in a reflow oven, so that the lead wires 102 and the corresponding resonance posts 101 are welded. In the transferring and welding processes, the positions of the conducting wire 102 and the resonant column 101 can be kept stable due to the limiting effect of the fixing groove 111 and the wire clamping groove.

Also, there are a plurality of the wire clamp grooves and the fixing grooves 111 in one-to-one correspondence. Therefore, the welding operation of the plurality of groups of conducting wires 102 and the resonant column 101 can be performed simultaneously, and the welding efficiency can be improved.

Referring to fig. 4, in the embodiment, the surface of the base 110 is further provided with a locking groove 115 communicating with the positioning groove 113, and the resonant beam welding fixture 100 further includes a locking assembly 140. The locking assembly 140 includes a slider 141 received in the locking groove 115 and a compression spring 143 interposed between the slider 141 and an inner wall of the locking groove 115. The side of the slider 141 remote from the compression spring 143 is urged against the leg 124 by the compression spring 143.

The slider 141 is slidably installed in the locking groove 115, and one end thereof can be inserted into the positioning groove 113, and the compression spring 143 provides a preload to the slider 141. Specifically, the slider 141 is T-shaped, and has a sidewall with an accommodating hole for accommodating the compression spring 143, so as to mount the compression spring 143.

Due to assembly tolerances, when the leg 124 is inserted into the detent 113, there may be a slight gap between the leg and the detent, resulting in slight wobble of the plate 120. The sliding block 141 can be abutted against the supporting leg 124 under the action of the compression spring 143, so that the supporting leg 120 is clamped between the inner wall of the positioning groove 113 and the sliding block 141 to prevent the support plate 120 from sliding, thereby further ensuring that the positions of the lead 102 and the resonant column 101 are kept stable in the welding process.

Further, in the present embodiment, the locking assembly 140 further includes a limiting plate 145, and the limiting plate 145 is installed at an edge of the locking groove 115 and covers the locking groove 115. Specifically, the stopper 145 may be fixed to the surface of the base 110 by a screw, and the stopper 145 is used to close the opening of the locking groove 115, so as to prevent the slider 141 and the compression spring 143 from falling off from the locking groove 115.

Referring to fig. 3 again, in the present embodiment, a magnet 150 is embedded in at least one of the support plate 120 and the pressing plate 130, and the support plate 120 and the pressing plate 130 are attracted by the magnet 150.

Specifically, the support plate 120 and the pressing plate 130 are detachably connected by the attraction of the magnet 150, and the clamping force is generated by the attraction of the magnet 150. Wherein, when a force larger than the attraction force of the magnet 150 is applied, the support plate 120 can be separated from the pressing plate 130; when the two are close to each other, the two can be matched again. Thus, installation of the lead 102 can be made more convenient.

Further, in the present embodiment, the magnet 150 is also located on the support plate 120, and the magnet 150 is disposed between two adjacent bar-shaped grooves 123.

At this time, the plurality of magnets 150 are alternately arranged with the bar-shaped grooves 123 on the platen 120. When the support plate 120 and the pressing plate 130 are attached by the magnets 150, the magnets 150 on both sides of each wire clamp groove provide clamping force, so that the wires 102 in the wire clamp grooves can be clamped more tightly.

In this embodiment, one end of the strip-shaped groove 123 far away from the fixing groove 111 is bent, so that the strip-shaped groove 123 is L-shaped. Therefore, the shape of the lead 102 is adjusted to be L-shaped by placing the lead in the bar-shaped groove 123. At this time, the L-shaped strip groove 123 is matched with the wire 102 to limit the wire 102 along the axial direction of the wire clamping groove, so that the wire 102 is prevented from being drawn in the wire clamping groove, and the position stability of the wire 102 is further ensured.

In this embodiment, the support plate 120 and the pressing plate 130 are respectively provided with an operating window 160 penetrating through the support plate 120 and the pressing plate 130 at a position corresponding to the plurality of wire clipping slots, and each wire clipping slot penetrates through the corresponding operating window 160.

Specifically, the operation window 160 is formed by a through hole opened at a position corresponding to the stay 120 and the pressing plate 130. As each wire clip slot passes through a corresponding operating window 160, the wire 102 within each wire clip slot also passes through the corresponding operating window 160. Before welding, if the position of the lead 102 does not meet the welding requirement, the lead can be directly finely adjusted through the operation window 160, so that the support plate 120 and the pressing plate 130 are prevented from being disassembled and assembled, and the convenience of operation is further improved.

The resonance column welding fixture 100 can fix the resonance column 101 in the fixing groove 111. Further, the pressing plate 130 is separated from the support plate 120, the lead 102 is placed in the strip-shaped groove 123, and the matching surface and the clamping surface 121 are attached again, so that the lead 102 can be fixed. Since one end of the clip slot is directed to the corresponding fixing slot 111, the conductive wire 102 in the clip slot can be extended to the surface of the corresponding resonant post 101 by selecting a suitable length of the conductive wire. The resonant post soldering fixture 100 with the fixed wire 102 and the resonant post 101 is placed in a reflow oven, so that the wire 102 and the corresponding resonant post 101 are soldered. In the welding process, the resonant column 101 and the conductive wire 102 are respectively fixed in position under the limiting action of the fixing groove 111 and the wire clamp groove, so that the phenomena of displacement, blurring and the like of welding spots caused by position deviation are avoided. Therefore, the welding fixture 100 for the resonant post can effectively improve the welding effect of the resonant post.
