[0004] In the above patent, the common mode filter is clamped and fixed by pulling two clamping plates by two springs. Since the shape and position of the clamping plates are almost fixed, the device can only perform glue dispensing operations on common mode filters of one specification, which reduces the scope of application of the device.

DETAILED DESCRIPTION

[0022] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The utility model provides a technical solution: Figure 1-5 The utility model discloses a glue dispensing device for common mode filter production, including a base plate 1 for mounting the glue dispensing device body, a positioning assembly 2 is provided on the base plate 1, the positioning assembly 2 includes two clamping plates 21, the two clamping plates 21 are relatively arranged at the middle position of the top side of the base plate 1, and elastic mechanisms 22 are provided on the left and right sides of the two clamping plates 21, and an adjustment mechanism 3 is provided on the elastic mechanism 22.

[0024] In this embodiment, when the improved common-mode filter dispensing device is used, the operator can adjust the spacing between the two clamping plates 21 by the mutual cooperation of the adjustment mechanism 3 and the elastic mechanism 22, and at the same time, the elastic mechanism 22 automatically and synchronously performs adaptive adjustment of the thrust of the clamping plate 21, so that the clamping force of the clamping plate 21 on the common-mode filter remains almost unchanged, and then the operator directly holds the common-mode filter and inserts the common-mode filter between the two clamping plates 21. At this time, the elastic mechanism 22 drives the two clamping plates 21 to automatically clamp the common-mode filter on both sides of the common-mode filter and fix it on the base plate 1, and then the operator can perform the dispensing processing operation of the common-mode filter according to the patent shown in the above background technology.

[0025] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the clamping plate 21 includes a limiting strip 211, the top side of the limiting strip 211 is arranged in an inclined shape, and the bottom side of the limiting strip 211 is clearance-matched with the bottom plate 1;

[0026] In this embodiment, during the above operation of inserting the common mode filter between the two clamping plates 21, due to the mutual interference between the common mode filter and the top side inclined surface of the limiting strip 211, the limiting strip 211 is pushed toward both sides along the inclined surface of the limiting strip 211, and the distance between the two limiting strips 211 is further adjusted, so that the common mode filter can be smoothly inserted between the two limiting strips 211, and the clamping and fixing operation of the common mode filter is simple.

[0027] In a further preferred embodiment of the present invention, Figure 1 - Figure 3 As shown, a plurality of rollers 212 are relatively rotatably mounted in the limit strip 211, and the spacing between two adjacent rollers 212 is equal. A guide groove 213 is provided at the top side of the bottom plate 1 at the position corresponding to the roller 212, and the bottom end of the roller 212 is inserted into the corresponding guide groove 213 and contacts the inner bottom wall of the corresponding guide groove 213;

[0028] In this embodiment, when the limit bar 211 moves on the base plate 1, due to the mutual interference between the roller 212 and the inner wall of the guide groove 213, the limit bar 211 moves on the base plate 1 in a left-right linear trajectory, and the rotation of the roller 212 can greatly offset the friction between the limit bar 211 and the base plate 1, so that when the common mode filter and the inclined surface of the limit bar 211 interfere with each other, the limit bar 211 can be easily pushed to slide to both sides.

[0029] In a further preferred embodiment of the present invention, Figure 1 and Figure 4As shown, the elastic mechanism 22 includes a square tube 221, and the two square tubes 221 are relatively arranged on the left and right sides of the two limit strips 211, and the bottom side of each square tube 221 is fixedly connected to the bottom plate 1, and a piston rod 222 is slidably installed in the square tube 221, and one end of the piston rod 222 close to the limit strip 211 is fixedly connected to the corresponding limit strip 211, and the square tube 221 is filled with air;

[0030] In this embodiment, the gas in the piston cylinder pushes the piston rod 222 to drive the two clamping plates 21 to clamp and fix the common mode filter. There are no elastic parts inside, and the reciprocating movement of the clamping plates 21 will not cause metal fatigue of the internal elastic parts to affect the use of the device, thereby reducing the maintenance cost of the device.

[0031] In a further preferred embodiment of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the adjustment mechanism 3 includes a piston plate 31, which is arranged in the corresponding piston cylinder, and the outer peripheral wall of the piston plate 31 contacts the inner wall of the corresponding square cylinder 221, a rectangular hole 32 is opened at the center position of the inner wall of one end of the square cylinder 221 away from the limit strip 211, and the interior of the rectangular hole 32 is communicated with the interior of the corresponding square cylinder 221, a square rod 33 is slidably installed in the rectangular hole 32, and one end of the square rod 33 is fixedly connected to the corresponding piston plate 31, a sealing ring 34 is fixedly installed in the cylinder wall of the open end of the square cylinder 221, and the inner ring wall of the sealing ring 34 contacts the outer peripheral wall of the corresponding piston rod 222;

[0032] In this embodiment, due to the mutual interference between the square rod 33 and the inner wall of the square hole, the moving trajectory of the piston plate 31 can be limited and constrained, so that the piston plate 31 moves in a left and right linear trajectory in the square cylinder 221.

[0033] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, a threaded hole 35 is formed at the other end of the square rod 33, a threaded rod 36 is provided in the square tube 221, and one end of the threaded rod 36 is inserted into the corresponding threaded hole 35 and threadedly connected with the inner wall of the corresponding threaded hole 35, and the other end of the threaded rod 36 extends to the outside of the square tube 221 and is rotatably connected with the tube wall of the corresponding square tube 221, and a knob 37 is fixedly mounted at the other end of the threaded rod 36;

[0034] In this embodiment, when adjusting the spacing between the two clamping plates 21, the operator rotates the threaded rod 36 through the knob 37 to push the piston plate 31 to move in a left and right linear trajectory in the square tube, thereby adjusting the spacing between the piston rod 222 plug plate and the piston plate 31, and synchronously adjusting the air pressure between the piston plate 31 and the piston plate 31. Due to the push of the gas between the piston plate 31 and the piston rod 222 on the piston rod 222, the piston rod 222 of the corresponding length is pushed out from the square tube 221. At the same time, as the piston rod 222 moves, the air pressure between the piston rod 222 plug plate and the inner wall of the piston tube opening increases synchronously due to the movement of the piston rod 222 until it is equal to the pressure between the piston plate 31 and the piston rod 222. Finally, the spacing between the two limit strips 211 can be adjusted to an appropriate length as needed.

[0035] Working principle: When the improved common mode filter dispensing device is used, the operator first rotates the threaded rod 36 through the knob 37. Due to the mutual interference between the square rod 33 and the inner wall of the square hole, the rotating threaded rod 36 pushes the piston plate 31 to move in a left and right linear trajectory in the square hole, thereby adjusting the distance between the piston rod 222 plug plate and the piston plate 31, and then adjusting the air pressure between the piston plate 31 and the piston plate 31. Due to the push of the gas between the piston plate 31 and the piston rod 222 on the piston rod 222, the piston rod 222 of the corresponding length is pushed out from the square tube 221. At the same time, as the piston rod 222 moves, the air pressure between the piston rod 222 plug plate and the inner wall of the piston tube opening increases synchronously due to the movement of the piston rod 222 until it is equal to the pressure between the piston plate 31 and the piston rod 222. Finally, the distance between the two limit strips 211 can be adjusted to a suitable length as needed;

[0036] It should be noted that the piston rod 222 can move synchronously with the limit bar 211 during its movement, and due to the mutual interference between the roller 212 and the inner wall of the guide groove 213, the limit bar 211 moves in a linear track in the left and right directions;

[0037] After the spacing adjustment of the above-mentioned limit strip 211 bracket is completed, the operator holds the common-mode filter and inserts the common-mode filter between the two limit strips 211. Due to the mutual interference between the common-mode filter and the top side inclined surface of the limit strip 211, the limit strip 211 is pushed toward both sides along the inclined surface of the limit strip 211, thereby applying a thrust to the piston rod 222 to further compress the gas in the square cylinder 221, providing power for the limit strip 211 to clamp the common-mode filter. At the same time, the spacing between the two limit strips 211 is further adjusted, so that the common-mode filter can be smoothly inserted between the two limit strips 211. After the common-mode filter is inserted between the two limit strips 211, due to the push of the piston rod 222 by the gas in the square cylinder 221, the two limit strips 211 clamp and limit the common-mode filter with a specific force from both sides of the common-mode filter, so that the common-mode filter is placed more stably on the bottom plate 1, and the clamping and fixing of the common-mode filter is completed. The operator can perform glue dispensing processing on the common-mode filter according to the patent shown in the above-mentioned background technology.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
