Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to a capacitor assembly welding jig. Background Art

[0002] Existing smart AI cameras usually include circuit boards assembled with large capacitors due to product usage requirements. At present, when assembling large capacitors with circuit boards, a simple jig is generally used to position the circuit board. After inserting the large capacitor, the two pins of the large capacitor are directly welded to the circuit board. After welding, the next step is to dispense glue between the capacitor and the circuit board through an automatic glue dispenser. If the relative position between the capacitor and the circuit board is not fixed, it is easy to cause the needle to bend and the product to be damaged during the operation of the automatic glue dispenser, seriously affecting the glue dispensing operation yield and product quality.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] refer to Figure 1 The capacitor assembly welding jig in the embodiment of the utility model may include a jig base plate 100, a first positioning carrier 200, a second positioning carrier 300 and a positioning cover plate 400, wherein the first positioning carrier 200, the second positioning carrier 300 and the positioning cover plate 400 are all arranged on the jig base plate 100. The first positioning carrier 200 is fixed to the jig base plate 100, the second positioning carrier 300 can be rotatably connected to the side of the first positioning carrier 200 away from the jig base plate 100 relative to the first positioning carrier 200, and the jig cover plate can be rotatably connected to the side of the second positioning carrier 300 away from the first positioning carrier 200 relative to the second positioning carrier 300.

[0029] Specific, combined Figure 1 and Figure 2 , the first positioning carrier 200 can be used to place the circuit board 10 and position the circuit board 10. Exemplarily, a first positioning groove 210 is provided on the side of the first positioning carrier 200 away from the fixture bottom plate 100. The shape of the first positioning groove 210 is adapted to the shape of the circuit board 10. When the circuit board 10 is placed in the first positioning groove 210, the side edges of the circuit board 10 can abut against the side walls of the first positioning groove 210, so that the first positioning groove 210 plays a role in limiting the circuit board 10, ensuring that the circuit board 10 and the first positioning carrier 200 remain relatively fixed.

[0030] Furthermore, a second positioning groove 220 is further provided on the side of the first positioning carrier 200 away from the fixture bottom plate 100. The shape of the second positioning groove 220 is adapted to the shape of the capacitor 20. The capacitor 20 can be placed in the second positioning groove 220. The second positioning groove 220 can pre-position the capacitor 20 so that the capacitor 20 and the first positioning carrier 200 remain relatively fixed. In addition, the bottom surface of the second positioning groove 220 can be an arc surface. When the capacitor 20 is placed in the second positioning groove 220, the bottom of the second positioning groove 220 fits the surface of the capacitor 20, thereby helping to improve the accuracy of the positioning of the capacitor 20.

[0031] For reference Figures 1 to 3 , the second positioning carrier 300 is located on the side of the first positioning carrier 200 away from the fixture bottom plate 100, one end of the second positioning carrier 300 can rotate relative to the first positioning carrier 200, and the other end of the second positioning carrier 300 is provided with a third positioning groove 310 that penetrates along its own thickness direction, and one end of the third positioning groove 310 has an opening. When the second positioning carrier 300 is rotated to fit with the surface of the first positioning carrier 200, the third positioning groove 310 is directly opposite to the second positioning groove 220, and the width of the third positioning groove 310 is greater than the width of the second positioning groove 220. At this time, the capacitor 20 can be placed in the third positioning groove 310, the bottom of the capacitor 20 fits with the bottom surface of the second positioning groove 220, and the side wall of the third positioning groove 310 can abut against the surface of the capacitor 20. Furthermore, the portion of the capacitor 20 with the pin 21 can extend out of the third positioning groove 310 through the opening of the third positioning groove 310 , thereby the third positioning groove 310 cooperates with the second positioning groove 220 to accurately position the capacitor 20 .

[0032] Continue to refer Figure 1 and Figure 3The positioning cover plate 400 is located at one side of the second positioning carrier 300. One end of the positioning cover plate 400 can be rotatably connected to the second positioning carrier 300 relative to the second positioning carrier 300, and the other end is provided with a positioning block 410. The positioning block 410 protrudes from the side of the positioning cover plate 400 facing the second positioning carrier 300 along the thickness direction of the positioning cover plate 400. When the positioning cover plate 400 is rotated to fit the second positioning carrier 300, the positioning block 410 can abut against the surface of the circuit board 10, and the positioning block 410 is located between the two pins 21, and the two pins 21 abut against the positioning block 410 respectively. Therefore, the capacitor 20 can maintain its position and relative fixity with respect to the circuit board 10 under the multiple limiting conditions of the second positioning groove 220, the third positioning groove 310 and the positioning cover 400, and the two pins 21 of the capacitor 20 are separated by the positioning block 410. When the two pins 21 are respectively soldered to the circuit board 10, a short circuit between the two pins 21 can be prevented, thereby ensuring the precise welding position between the capacitor 20 and the circuit board 10. When the capacitor 20 is subsequently glued, the glue dispensing quality can be guaranteed, thereby ensuring the product quality.

[0033] It should be noted that the thickness direction mentioned in this embodiment can be understood as the arrangement direction between the jig base plate 100 and the positioning cover plate 400 when the jig base plate 100, the first positioning carrier 200, the second positioning carrier 300 and the positioning cover plate 400 are stacked in sequence.

[0034] refer to Figures 1 to 4 , a side of the positioning cover plate 400 facing the second positioning carrier 300 is provided with an avoidance groove 420 at a position corresponding to the third positioning groove 310. The avoidance groove 420 can be used to avoid the capacitor 20 when the positioning cover plate 400 is attached to the second positioning carrier 300, so as to prevent the positioning cover plate 400 from squeezing the capacitor 20 and causing damage to the capacitor 20. In addition, the bottom surface of the avoidance groove 420 is an arc surface. When the positioning cover plate 400 is attached to the second positioning carrier 300, the surface of the capacitor 20 can be attached to the bottom surface of the avoidance groove 420. In this embodiment, the second positioning groove 220 and the avoidance groove 420 cooperate to prevent the capacitor 20 from moving up and down, the second positioning groove 220 can also prevent the capacitor 20 from moving forward and backward, and the third positioning groove 310 can prevent the capacitor 20 from moving left and right, thereby achieving accurate positioning of the capacitor 20.

[0035] refer to Figures 2 to 4To ensure that after the second positioning carrier 300 is rotated to fit against the first positioning carrier 200, the first positioning carrier 200 and the second positioning carrier 300 can be accurately positioned and kept relatively fixed, and to ensure that after the positioning cover plate 400 is rotated to fit against the second positioning carrier 300, the positioning cover plate 400 and the second positioning carrier 300 can be accurately positioned and kept relatively fixed, a first positioning component and a first magnetic attraction component 500 are provided between the first positioning carrier 200 and the second carrier, and a second positioning component and a second magnetic attraction component 600 are provided between the second positioning carrier 300 and the positioning cover plate 400.

[0036] Specifically, the first positioning assembly includes a plurality of first positioning pins 230 disposed on the side of the first positioning carrier 200 facing the second positioning carrier 300 and a plurality of first positioning holes 320 disposed on the second positioning carrier 300. The plurality of first positioning holes 320 are disposed in a one-to-one correspondence with the plurality of first positioning pins 230. When the second positioning carrier 300 is rotated to fit the first positioning carrier 200, each first positioning pin 230 is located in the corresponding first positioning hole 320. The second positioning assembly includes a plurality of second positioning pins 330 disposed on the side of the second positioning carrier 300 facing the positioning cover plate 400 and a plurality of second positioning holes 430 disposed on the positioning cover plate 400. The plurality of second positioning holes 430 are disposed in a one-to-one correspondence with the plurality of second positioning pins 330. When the positioning cover plate 400 is rotated to fit the second positioning carrier 300, each second positioning pin 330 is located in the corresponding second positioning hole 430. In this way, it can be ensured that when the first positioning carrier 200 , the second positioning carrier 300 and the positioning cover plate 400 are in a stacked state, the three can be accurately positioned, thereby ensuring accurate positioning between the capacitor 20 and the circuit board 10 .

[0037] Furthermore, the first magnetic attraction component 500 may include a magnet disposed on the side of the first positioning carrier 200 facing the second positioning carrier 300 and a magnet disposed on the side of the second positioning carrier 300 facing the first positioning carrier 200. When the second positioning carrier 300 is attached to the first positioning carrier 200, the two can be relatively fixed by the magnetic attraction of the magnets on both sides. The second magnetic attraction component 600 may include a magnet disposed on the side of the second positioning carrier 300 facing the positioning cover plate 400 and a magnet disposed on the side of the positioning cover plate 400 facing the second positioning carrier 300. When the positioning cover plate 400 is attached to the second positioning carrier 300, the two can also be relatively fixed by the magnetic attraction of the magnets on both sides.

[0038] In this embodiment, the second positioning carrier 300 can be connected to the first positioning carrier 200 through a stainless steel hinge, which can not only ensure the flipping accuracy, but also enable the second positioning carrier 300 to hover when flipped to be perpendicular to the first positioning carrier 200, so as to facilitate the placement of the capacitor 20. Similarly, the positioning cover 400 can also be connected to the second positioning carrier 300 through a stainless steel hinge, which can facilitate the placement of the capacitor 20 while ensuring the flipping accuracy.

[0039] In some embodiments, reference Figure 4 The positioning cover plate 400 includes a fixed cover plate 440 and a movable cover plate 450. One end of the fixed cover plate 440 can be rotatably connected to the second positioning carrier 300 relative to the second positioning carrier 300, and the other end of the fixed cover plate 440 is connected to the movable cover plate 450. The positioning block 410 is disposed at one end of the movable cover plate 450 away from the fixed cover plate 440. In this embodiment, when the positioning cover plate 400 is attached to the second positioning carrier 300, one side of the fixed cover plate 440 connected to the movable cover plate 450 is at least flush with the side of the second positioning carrier 300, or exceeds the side of the second positioning carrier 300. That is to say, when the positioning cover plate 400 is flipped to fit the second positioning carrier 300, the second positioning carrier 300 and the fixed cover plate 440 are relatively fixed, and the movable cover plate 450 does not contact the second positioning carrier 300.

[0040] The movable cover plate 450 can move relative to the fixed cover plate 440 along the arrangement direction of the two pins 21 of the capacitor 20, thereby changing the contact position of the positioning block 410 with the circuit board 10, and further adjusting the positions of the two pins 21. Specifically, the movable cover plate 450 is provided with strip holes 451 on both sides of the positioning block 410, each strip hole 451 penetrates the movable cover plate 450 along the mine clearance direction of the movable cover plate 450 and the fixed cover plate 440, and two positioning posts (not shown in the figure) corresponding to the two strip holes 451 are provided on one side of the fixed cover plate 440 facing the movable cover plate 450, and each positioning post is fixedly connected to the fixed cover plate 440.

[0041] Each fixed column can be extended into the corresponding strip hole 451, and the positioning column and the strip hole 451 are interference fit along the thickness direction of the positioning cover plate 400. Thus, the movable cover plate 450 and the fixed cover plate 440 can be relatively fixed to ensure that the movable cover plate 450 will not fall off the fixed cover plate 440 during the flipping process of the positioning cover plate 400. Along the arrangement direction of the two pins 21 of the capacitor 20, the size of the strip hole 451 is larger than the size of the positioning column. When the movable cover plate 450 is pushed from the left and right sides of the movable cover plate 450 by external force, the relative position between the positioning column and the strip hole 451 can change, that is, the relative position between the movable cover plate 450 and the fixed cover plate 440 changes, and the position of the positioning block 410 is offset. Through the connection design of the movable cover plate 450 and the fixed cover plate 440, the left and right positions of the positioning block 410 can be appropriately adjusted, so as to facilitate the adjustment of the welding position between the pins 21 and the circuit board 10.

[0042] Combined with the introduction of the capacitor assembly welding jig in the above embodiment, the capacitor assembly welding jig in this embodiment can refer to the following steps when welding the capacitor 20 to the circuit board 10:

[0043] Step 1: Flip the second positioning carrier 300 and the positioning cover plate 400 to a position away from the first positioning carrier 200;

[0044] Step 2: Place the circuit board 10 in the first positioning groove 210 of the first positioning carrier 200, and flip the second positioning carrier 300 to fit the surface of the first positioning carrier 200;

[0045] Step 3: placing the capacitor 20 in the third positioning groove 310;

[0046] Step 4: Flip the positioning cover plate 400 to fit with the second positioning carrier 300;

[0047] Step 5: Solder the two pins 21 of the capacitor 20 to the circuit board 10 respectively;

[0048] Step 6: Flip the second positioning carrier 300 and the positioning cover plate 400 again to a position away from the first positioning carrier 200, and take out the welded product.

[0049] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
