[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] It is understandable that, referring to Figures 1 to 6The capacitor solder positioning device of the present invention comprises a first positioning mechanism 100, a second positioning mechanism 200 and a locking mechanism 300. The first positioning mechanism 100 comprises a bottom plate 110 and a cover plate 120. The cover plate 120 is rotatably connected to the bottom plate 110. The bottom plate 110 is provided with a plurality of first positioning components 130. The first positioning components 130 comprise a first positioning block 131 and a first positioning pin 132. The first positioning pin 132 can be penetrated in the positioning portion of the electrode plate. The upper end surface of the first positioning block 131 is provided with a first positioning groove 133. The first positioning groove 133 can clamp the positioning portion of the electrode plate. The cover plate 120 is provided with a plurality of first positioning components 130. The second positioning component 140 corresponds to the first positioning component 130 one by one. The second positioning component 140 includes a sleeve 141 and a second positioning pin 142. The sleeve 141 can be sleeved on the first positioning pin 132 so that the sleeve 141 abuts against the positioning portion of the electrode plate, and the second positioning pin 142 can pass through the positioning portion of the electrode plate; the second positioning mechanism 200 includes a slider 210, the slider 210 is slidably connected to the base plate 110, and the slider 210 can move in a direction close to the first positioning block 131 to abut against the positioning capacitor element; the locking mechanism 300 is used to lock the cover plate 120 on the base plate 110.

[0023] The capacitor is placed on the bottom plate 110, so that the electrode plate below abuts against the bottom plate 110, and the multiple positioning parts of the electrode plate are respectively clamped in the first positioning groove 133 and sleeved on the first positioning pin 132. The first positioning groove 133 and the first positioning pin 132 are used to pre-position the position of the electrode plate. A set of first positioning components 130 can pre-position one electrode plate, and then the slider 210 is moved in the direction close to the first positioning block 131 to abut and position the capacitor element, which can reduce the possibility of position deviation caused by the capacitor element moving between the two electrode plates. Then, the cover plate 120 is rotated to cover the bottom plate 110, so that the sleeve 1 41 is sleeved on the first positioning pin 132 so that the sleeve 141 abuts the positioning part of the electrode plate, thereby cooperating with the first positioning pin 132 to clamp and position the positioning part of the electrode plate, and at the same time, the second positioning pin 142 is inserted into the positioning part in the first positioning groove 133. The position of the electrode plate can be positioned by cooperating with the first positioning pin 132 and the second positioning pin 142, which can replace manual tightening of bolts for positioning, thereby improving positioning efficiency and positioning accuracy. Finally, the cover plate 120 is locked on the base plate 110 through the locking mechanism 300, so that the cover plate 120 abuts against the upper electrode plate, and cooperates with the base plate 110 to clamp and fix the capacitor, which can improve the stability of positioning.

[0024] It should be noted that the capacitor has at least two electrode plates, each electrode plate has at least two positioning parts, the positioning parts have through holes, and the positioning parts can be inserted into the first positioning pin 132 or the second positioning pin 142 through the through holes. At least one positioning part of each electrode plate is inserted into the first positioning pin 132, and at least one positioning part is clamped in the first positioning groove 133 and inserted into the second positioning pin 142, so that the position of the electrode plate can be positioned.

[0025] The sleeve 141 corresponds to the first positioning pin 132 one by one, and the position of the positioning part is pre-positioned by the first positioning pin 132, so that the sleeve 141 can abut against the positioning part to position the positioning part. The second positioning pin 142 corresponds to the first positioning block 131 one by one, and the position of the positioning part is pre-positioned by clamping the positioning part through the first positioning groove 133, so that the second positioning pin 142 can be aligned with the through hole of the insertion positioning part, so that it can cooperate with the first positioning pin 132 to position the electrode plate.

[0026] The slider 210 and the first positioning block 131 are respectively arranged on opposite sides of the base plate 110. The shape of the first positioning groove 133 matches the shape of the positioning portion. The side wall of the first positioning groove 133 abuts the positioning portion, which can limit the electrode plate from moving or rotating in a direction away from the slider 210, thereby positioning the electrode plate. The electrode plate has an abutting portion, which can abut the capacitor element to limit the capacitor element from moving in a direction close to the first positioning block 131. Therefore, the slider 210 can cooperate with the abutting portion to clamp and position the capacitor element.

[0027] After the slider 210 moves to a preset position to position the positioning portion, the position of the slider 210 can be fixed by fasteners such as latches or bolts.

[0028] It is understandable that, referring to Figure 1 , Figure 2 , Figure 5 and Figure 6The second positioning mechanism 200 further includes a stopper 220 and a first spring 230. The stopper 220 is rotatably connected to the bottom plate 110. A slot 221 is provided at the upper end of the stopper 220. Two ends of the first spring 230 are respectively connected to the bottom plate 110 and the stopper 220. The first spring 230 can drive the stopper 220 to rotate in a direction close to the slider 210 so that the slider 210 can be inserted into the slot 221. The stopper 220 is driven to rotate in a direction close to the slider 210 by the first spring 230, so that the stopper 220 abuts against the slider 210. When the slider 210 moves to a preset position in a direction close to the first positioning block 131, the slider 210 slides along the upper end surface of the stopper 220 to the slot 221, so that the slider 210 is inserted into the slot 221, thereby positioning the slider 210 to improve the positioning stability. During disassembly, the stop block 220 is rotated away from the slider 210 to disengage the slider 210 from the slot 221 , thereby moving the slider 210 away from the first positioning block 131 to release the positioning of the capacitor element and facilitate disassembly of the capacitor.

[0029] It should be noted that the side wall of the slot 221 abuts against the slider 210 to limit the slider 210 from moving in a direction away from the first positioning block 131 .

[0030] A pull rod 222 may be provided on a side of the stop block 220 away from the slider 210 , and the stop block 220 may be driven to rotate by the pull rod 222 , so that an operator can apply force to rotate the stop block 220 .

[0031] Specifically, refer to Figure 1 and Figure 2 The bottom plate 110 is provided with a guide rod 240, which is arranged in a horizontal direction close to the first positioning block 131, and the slider 210 is slidably connected to the guide rod 240. Since the guide rod 240 is arranged in a horizontal direction close to the first positioning block 131, the slider 210 is guided by the guide rod 240 to move in a horizontal direction close to the first positioning block 131, which can reduce the shaking and deviation of the slider 210, thereby improving the stability of the movement of the slider 210, thereby improving the accuracy of the positioning position.

[0032] Specifically, refer to Figure 1 and Figure 2 The guide rod 240 is sleeved with a second spring 250, and the two ends of the second spring 250 are respectively connected to the bottom plate 110 and the slider 210, and the second spring 250 can drive the slider 210 to move away from the first positioning block 131. When the stop block 220 rotates in the direction away from the slider 210, the slider 210 is disengaged from the slot 221, and the slider 210 is driven by the second spring 250 to move in the direction away from the first positioning block 131, so that the slider 210 can be quickly reset, thereby facilitating the removal of the capacitor.

[0033] It is understandable that, referring to Figure 1 and Figure 6 The slider 210 is provided with a limit block 211, which can abut against the electrode plate to locate the position of the electrode plate. The limit block 211 abuts against the electrode plate to locate the position of the electrode plate, thereby improving the stability of the electrode plate positioning. In addition, the limit block 211 presses the insulating paper on the electrode plate to reduce the possibility of the insulating paper contacting the capacitor element due to warping.

[0034] It is understandable that, referring to Figure 2 and Figure 6 A plurality of second positioning blocks 212 are provided on one side of the slider 210 close to the first positioning block 131. The plurality of second positioning blocks 212 are arranged at intervals in the horizontal direction, and a second positioning groove 213 is formed between two adjacent second positioning blocks 212. The side wall of the second positioning groove 213 can abut against the side wall of the capacitor element. The position of the capacitor element is positioned by abutting the side wall of the second positioning groove 213 against the side wall of the capacitor element, which can reduce the possibility of the capacitor element shaking in the horizontal direction, thereby improving the stability of positioning.

[0035] It should be noted that the shape of the second positioning groove 213 matches the shape of the side wall of the capacitor element, which can increase the contact area between the side wall of the second positioning groove 213 and the capacitor element, thereby dispersing the force to improve the stability of the positioning of the capacitor element.

[0036] The capacitor may include a plurality of capacitor elements. By individually positioning each capacitor element through a plurality of second positioning grooves 213 , mutual influence between the capacitor elements can be reduced, thereby improving the position stability of the capacitor elements.

[0037] Specifically, refer to Figure 2 and Figure 6 The second positioning block 212 is provided with a partition 214, which can extend into the gap between two adjacent capacitor elements, and the two side walls of the partition 214 can respectively abut the two adjacent capacitor elements. By extending the partition 214 into the gap between two adjacent capacitor elements, and the two side walls of the partition 214 respectively abutting the two adjacent capacitor elements, the two adjacent capacitor elements can be separated, reducing the possibility of abutment and collision between the capacitor elements, so as to reduce the mutual influence between the capacitor elements after solder positioning.

[0038] It is understandable that, referring to Figure 2 and Figure 4The bottom wall of the first positioning groove 133 is provided with a first positioning hole 134, and the second positioning pin 142 can be inserted into the first positioning hole 134. By inserting the second positioning pin 142 into the first positioning hole 134, the position of the second positioning pin 142 can be positioned, thereby positioning the position of the positioning portion sleeved on the second positioning pin 142, so as to reduce the possibility of the positioning portion shaking and deviating, improve the stability of the electrode plate positioning, and reduce the possibility of the positioning portion slipping off the second positioning pin 142.

[0039] It should be noted that a second positioning hole 121 can be opened in the cover plate 120, and a third positioning pin 111 can be provided on the base plate 110. The third positioning pin 111 can be inserted into the second positioning hole 121. The relative position between the cover plate 120 and the base plate 110 is positioned by the cooperation of the third positioning pin 111 and the second positioning hole 121, thereby improving the docking accuracy between the sleeve 141 and the first positioning pin 132, and between the first positioning hole 134 and the second positioning pin 142, and can be quickly docked together to improve the positioning efficiency of the capacitor.

[0040] It is understandable that, referring to Figures 2 to 4 The locking mechanism 300 includes a hook 310 and a locking member 320. The hook 310 is disposed on one side of the cover plate 120, and the locking member 320 is disposed on one side of the bottom plate 110. The locking member 320 can be engaged with the hook 310. When the cover plate 120 is covered on the bottom plate 110, the locking member 320 is engaged with the hook 310 to limit the rotation of the cover plate 120, so that the cover plate 120 can be locked on the bottom plate 110, so that the capacitor can be quickly positioned between the cover plate 120 and the bottom plate 110, which can improve the positioning efficiency.

[0041] It should be noted that a hook 310 can be set on each of the opposite sides of the cover plate 120, and a locking piece 320 can be set on each of the opposite sides of the base plate 110. The hook 310 corresponds to the locking piece 320 one by one, and the cover plate 120 can be locked from the opposite sides of the base plate 110, thereby improving the locking stability.

[0042] Specifically, refer to Figures 2 to 4The locking member 320 includes a fixed plate 321, a rotating block 322, a hanging rod 323, a third spring 324 and two connecting rods 325. The fixed plate 321 is set on the bottom plate 110, the rotating block 322 is rotatably connected to the fixed plate 321, and the two connecting rods 325 are arranged facing each other along the length direction. One connecting rod 325 is hinged to the rotating block 322, and the other connecting rod 325 is connected to the hanging rod 323. Both connecting rods 325 are provided with a limiting portion 326. The third spring 324 is set between the two limiting portions 326, and the two ends of the third spring 324 can respectively abut the two limiting portions 326, and the hanging rod 323 can be clamped with the hook 310. When locked, the hanging rod 323 is connected to the hook 310, and then the rotating block 322 is rotated in the direction close to the fixed plate 321, so that the hinge point of the rotating block 322 and the connecting rod 325 moves in the direction away from the hook 310, and drives the connecting rod 325 hinged to the rotating block 322 to move in the direction away from the hook 310. Since one of the connecting rods 325 is hinged to the rotating block 322 and the other connecting rod 325 is connected to the hanging rod 323, both connecting rods 325 are provided with a limiting portion 326. The third spring 324 is arranged between the two limiting parts 326. When the connecting rod 325 hinged to the rotating block 322 moves, the connecting rod 325 connected to the hanging rod 323 does not move, so that the two limiting parts 326 move closer to each other, thereby compressing the third spring 324. The hanging rod 323 can be stabilized in the hook 310 through the third spring 324, reducing the possibility of the hanging rod 323 detaching from the hook 310, so as to improve the position stability between the cover plate 120 and the bottom plate 110, thereby improving the stability of the capacitor positioning. When unlocking, by rotating the rotating block 322 in the direction away from the fixed plate 321, the two connecting rods 325 move closer to each other, and at the same time, the third spring 324 elastically recovers, which facilitates the hanging rod 323 to detach from the hook 310, thereby improving the locking and unlocking efficiency.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
