Description

Technical Field

[0001] The invention belongs to the field of filter glue potting packaging. Background Art

[0002] The filter's glue potting and packaging process can effectively provide a more stable electrical environment, effectively reduce electromagnetic noise and signal interference inside the filter, and thus improve the electrical performance of the device; after the glue potting is cured, a protective layer is formed around the filter, which can effectively prevent air, moisture, dust and other external substances from entering the filter, and avoid these substances from corroding and damaging the electronic components inside the filter; the potting glue material has a certain thermal conductivity, which can effectively conduct the heat inside the filter and reduce the temperature of the device;

[0003] However, since there are coil elements in the glue potting chamber inside the filter, and the coil elements are distributed at both ends of the glue potting chamber, and since the potting glue has a certain viscosity, and the two large coil elements in the glue potting slot divide the nearby space into multiple gaps, after the potting glue with a certain viscosity is poured into the glue potting slot, large bubbles are easily formed in the gaps around and below the coil elements in the glue potting slot, and the bubbles are attached to the surrounding and bottom of the coil original in a static state; such large granular bubbles will not only affect heat dissipation, but thermal expansion and contraction will easily lead to problems such as cracking.

[0039] By respectively controlling the first drive motor 2a, the second drive motor 2b, the third drive motor 2c, the fourth drive motor 2d, the first deflection motor 4a, the second deflection motor 4b, the third deflection motor 4c and the fourth deflection motor 4d, the filter glue potting and packaging bubble suppression station 10 can achieve at least the following two states:

[0040] The first state: Figure 6 As shown, the axes of the first drive motor 2a, the second drive motor 2b, the third drive motor 2c and the fourth drive motor 2d are all vertical; the middle section of the first spiral profile surface 5a and the middle section of the second spiral profile surface 5b are both tangent to the left side surface of the filter unit 11 to be glued; the middle section of the third spiral profile surface 5c and the middle section of the fourth spiral profile surface 5d are both tangent to the right side surface of the filter unit 11 to be glued;

[0041] The second state: Figure 7 As shown in the figure below, the axes of the first drive motor 2a, the second drive motor 2b, the third drive motor 2c and the fourth drive motor 2d are all horizontal; the first step surface 6a and the second step surface 6b face upward and contact the left side of the bottom surface of the filter unit 11 to be poured with glue; the fourth step surface 6d and the third step surface 6c face upward and contact the right side of the bottom surface of the filter unit 11 to be poured with glue.

[0042] Working principle:

[0043] Step 1: by means of the cooperation between the manipulator and the annular turntable 9, a plurality of filter units 11 to be glued are placed one by one on the strip filter carrier 14 of a plurality of filter glue-filling and packaging bubble suppression stations 10;

[0044] Step 2, control each filter glue potting and packaging bubble suppression station 10 to enter the "first state". At this time, taking any filter glue potting and packaging bubble suppression station 10 as an example, the axes of the first drive motor 2a, the second drive motor 2b, the third drive motor 2c and the fourth drive motor 2d are all vertical; the middle section of the first spiral contour surface 5a and the middle section of the second spiral contour surface 5b are both tangent to the left side surface of the filter unit 11 to be potted; the middle section of the third spiral contour surface 5c and the middle section of the fourth spiral contour surface 5d are both tangent to the right side surface of the filter unit 11 to be potted; and the front and rear sections of the filter unit 11 to be potted are constrained by two clamping walls 15, so at this time, each filter unit 11 to be potted is completely positioned in the horizontal direction;

[0045] Step 3, control the annular turntable 9 to rotate along the axis, so that the filter units to be poured 11 on the plurality of filter glue filling and packaging bubble suppression stations 10 arrive directly below the glue outlet nozzle 8 one by one; when each filter unit to be poured 11 arrives directly below the glue outlet nozzle 8, the glue outlet nozzle 8 injects a certain amount of potting glue into the potting slot 12 of the filter unit to be poured 11 directly below, and the potting glue is epoxy resin potting glue or polyurethane potting glue; and the coil elements in the potting slot 12 are half submerged by the potting glue. When the coil elements in the potting slots 12 of all the filter units 11 on the annular turntable 9 are half submerged by the potting glue, the first stage of the potting process is completed;

[0046] Since the potting glue has a certain viscosity, and the two large coil elements in the potting notch 12 divide the nearby space into a plurality of small gaps, after the potting glue with a certain viscosity is poured into the potting notch 12, large bubbles are easily formed in the gaps around and below the coil elements in the potting notch 12, and the bubbles are attached to the surrounding and bottom of the coil original in a static state; such large granular bubbles will not affect heat dissipation, and thermal expansion and contraction will easily lead to problems such as cracking;

[0047] Step 4: Figure 6 As shown, based on the "first state", the first drive motor 2a, the second drive motor 2b, the third drive motor 2c and the fourth drive motor 2d are controlled simultaneously;

[0048] In a top-down perspective, the first spiral drive block 1a is controlled to rotate rapidly clockwise, the second spiral drive block 1b is controlled to rotate rapidly counterclockwise, the third spiral drive block 1c is controlled to rotate rapidly counterclockwise, and the fourth spiral drive block 1d is controlled to rotate rapidly clockwise; thereby, the front portion of the filter unit 11 to be glued is rapidly swung to the left around the adaptive rotating shaft 18 by a certain angle, specifically less than 5°; the rear portion of the filter unit 11 to be glued is rapidly swung to the right around the adaptive rotating shaft 18 by a certain angle; then, the first spiral drive block 1a is immediately controlled to rotate rapidly counterclockwise, the second spiral drive block 1b is controlled to rotate rapidly clockwise, the third spiral drive block 1c is controlled to rotate rapidly clockwise, and the fourth spiral drive block 1d is controlled to rotate rapidly counterclockwise; thereby, the front portion of the filter unit 11 to be glued is rapidly swung to the right around the adaptive rotating shaft 18 by a certain angle, and the rear portion of the filter unit 11 to be glued is rapidly swung to the left around the adaptive rotating shaft 18 by a certain angle;

[0049] This step is repeated n times in a periodic manner. Under the common constraint of the first spiral drive block 1a and the second spiral drive block 1b relative to the fourth spiral drive block 1d and the third spiral drive block 1c, the filter unit 11 to be glued is periodically oscillated back and forth around the adaptive rotating shaft 18, so that the two large coil elements in the glue-filling slot 12 are repeatedly and rapidly oscillated left and right, thereby promoting the separation and floating of large particle bubbles attached to the two large coils in the glue-filling slot 12, but the bubbles under the two large coil elements in the glue-filling slot 12 are still not easy to float;

[0050] Step 5: After Step 4 is completed, return to the first state;

[0051] Step six, "the first state", based on any filter glue potting and packaging bubble suppression station 10 as an example, control the output shafts of the first deflection motor 4a, the second deflection motor 4b, the third deflection motor 4c and the fourth deflection motor 4d to deflect 90°, so that the axes of the first drive motor 2a, the second drive motor 2b, the third drive motor 2c and the fourth drive motor 2d are all changed from vertical to horizontal, and then the first drive motor 2a, the second drive motor 2b, the third drive motor 2c and the fourth drive motor 2d are controlled respectively, so that the first step surface 6a and the second step surface 6b face upward and contact the left side of the bottom surface of the filter unit 11 to be potted; the fourth step surface 6d and the third step surface 6c face upward and contact the right side of the bottom surface of the filter unit 11 to be potted; thereby entering the "second state", such as Figure 8 As shown;

[0052] Step 7, based on the "second state", the first drive motor 2a, the second drive motor 2b, the third drive motor 2c and the fourth drive motor 2d are controlled simultaneously;

[0053] like Figure 8As shown, the first spiral drive block 1a, the second spiral drive block 1b, the third spiral drive block 1c and the fourth spiral drive block 1d are all controlled to rotate slowly clockwise by a certain angle; so that the left part of the filter unit 11 to be glued is slowly swung downward by a certain angle, and the right part is swung upward by a certain angle, and it is ensured that the potting glue in the glue potting slot 12 does not overflow; then the first spiral drive block 1a, the second spiral drive block 1b, the third spiral drive block 1c and the fourth spiral drive block 1d are all controlled to rotate slowly counterclockwise by a certain angle; so that the left part of the filter unit 11 to be glued is slowly swung upward by a certain angle, and the right part is swung downward by a certain angle, and it is ensured that the potting glue in the glue potting slot 12 does not overflow; this step is repeatedly run n times in a periodic manner, so that the left and right sides of the potting glue in the glue potting slot 12 repeatedly fluctuate up and down, so that a periodic swaying undercurrent is formed under the two large coils in the glue potting slot 12, thereby promoting the displacement and floating of large particle bubbles under the two large coils in the glue potting slot 12;

[0054] Step 8: After Step 7, restore to the first state.

[0055] Step nine, controlling the annular turntable 9 to rotate along the axis, and making the filter units 11 to be potted on the plurality of filter potting and packaging bubble suppression stations 10 arrive successively directly below the glue outlet nozzle 8 again; when each filter unit 11 to be potted arrives directly below the glue outlet nozzle 8, the glue outlet nozzle 8 injects a certain amount of potting glue into the potting slot 12 of the filter unit 11 to be potted directly below, and makes the coil elements in the potting slot 12 completely submerged in the potting glue. When the coil elements in the potting slots 12 of all the potted filter units 11 on the annular turntable 9 are submerged in the potting glue, the potting process of suppressing the bubbles around and at the bottom of the coil from floating up and being difficult to be discharged is completed.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
