[0041] In use, the glue filling cavity 3 of the glue filling tool 2 is aligned with the output nozzle 15 of the mixing barrel 14, then the operators operate the PLC control platform 11 to make the stirring mechanism in the barrel 12 stir the glue in the barrel 12 so as to ensure the uniformity of the glue, then the operators start the metering pump 13 and the first control valve 16 to work, the metering pump 13 draws the preset amount of glue in the corresponding barrel 12 into the mixing barrel 14, wherein the preset amount is the amount of glue input by the operators from the PLC control platform 11 according to the glue proportioning requirement; then the stirring mechanism in the mixing barrel 14 stirs the mixed glue, then the second control valve 17 is started to make the mixed glue enter the glue filling cavity 3 of the glue filling tool 2 from the output nozzle 15, thereby realizing the glue filling work.

By starting the vacuum pump through the PLC control platform 11, the glue barrel 12 can be vacuumized and defoamed after the glue in the glue barrel 12 is stirred, so as to reduce the air bubbles in the glue and further ensure the connection reliability of the cable and the connector 5.

[0044] Referring to Figure 1 And Figure 2 The glue filling device further comprises a glue storage barrel 18 and a glue pumping pump 19, both of which are in one-to-one correspondence with the glue barrels 12. The glue storage barrel 18 is connected with the corresponding glue barrel 12 through the corresponding glue pumping pump 19, and the glue pumping pump 19 is electrically connected with the PLC control platform 11. Specifically, the glue pumping pump 19 can adopt one of a glue pumping screw pump and a glue pumping gear pump. Through the cooperation of the glue pumping pump 19 and the glue storage barrel 18, automatic feeding into the glue barrel 12 can be realized, which is simple and convenient.

[0045] Referring to Figure 1 And Figure 2 The glue filling device further comprises a liquid level sensor (not shown in the figure), which is installed in the glue barrel 12 for detecting the liquid level of the glue in the glue barrel 12, and is wirelessly connected with the PLC control platform 11.

[0046] Referring to Figure 3 And Figure 4 In order to facilitate the fixing of the cable 4 and the connector 5, the glue filling tool 2 comprises two tool bodies 201 which can be detachably spliced with each other. Specifically, the two tool bodies 201 are connected by bolts or screws, so as to facilitate splicing and disassembly. The glue filling groove is formed on the side of each tool body 201, and the glue filling grooves on the two tool bodies 201 are spliced to form the glue filling cavity 3. The glue filling groove penetrates through the upper and lower sides of the tool body 201, so that the glue filling cavity 3 is a through groove. The upper end of the glue filling cavity 3 is used for feeding the glue, and the lower end of the glue filling cavity 3 is used for abutting against the connector 5.

[0047] Referring to Figure 3 And Figure 4The cable half-hole 6 is communicated with the glue pouring groove, two cable half-holes 6 on the two tooling bodies 201 are spliced to form a cable hole, specifically, the length direction of the cable hole is perpendicular to the length direction of the glue pouring cavity 3, and the number of the cable half-holes 6 can be set according to requirements, and in the embodiment of the application, two cable half-holes 6 are symmetrically provided along the vertical axis of the tooling body 201.

[0048] In use, the cable 4 is placed in the cable half-hole 6 between the two tooling bodies 201, and one end of the cable 4 in the glue pouring cavity 3 extends downward, then the connector 5 is connected with the cable 4 and abuts against the bottom wall of the tooling body 201, then the two tooling bodies 201 are abutted, the two tooling bodies 201 are fixed by bolts or screws, then the cable 4 and the connector 5 are fixed on the tooling body 201, at this time, the connector 5 seals the bottom wall of the glue pouring cavity 3, so that the connection part of the cable 4 and the connector 5 is located in the glue pouring cavity 3, so that the glue can be poured from the upper end of the glue pouring cavity 3, so as to pour and seal the connection of the cable 4 and the connector 5.

[0049] Referring to Figure 3 , Figure 4 and Figure 5 , in order to reduce the air bubbles in the glue during pouring, the bubble removing mechanism comprises a bubble removing ring 7, a piston ring 8, an operating member and an isolation assembly 9, wherein the bubble removing ring 7 is annular, the outer diameter of the bubble removing ring 7 is matched with the inner diameter of the glue pouring cavity 3, the inner diameter of the bubble removing ring 7 is matched with the outer diameter of the output nozzle 15, the bubble removing ring 7 is detachably arranged on the two tooling bodies 201, the bubble removing ring 7 is aligned with the glue pouring cavity 3 in the glue pouring tool 2 and is arranged concentrically with the glue pouring cavity 3, the bubble removing ring 7 is of a structure that the lower end is open and the upper end is closed, so that the output nozzle 15 is overlapped on the upper surface of the bubble removing ring 7, and the center of the bubble removing ring 7 is used for the output nozzle 15 of the glue pouring device to pass through, so as to facilitate the glue to enter the glue pouring cavity 3. Specifically, in order to facilitate the disassembly and assembly of the bubble removing ring 7, a plurality of connecting ears 22 are fixed on the outer wall of the bubble removing ring 7, and the connecting ears 22 are detachably connected with the tooling body 201 by bolts or screws.

[0050] Referring to Figure 3 and Figure 5 , the piston ring 8 is slidingly arranged in the bubble removing ring 7, the sliding direction of the piston ring 8 is parallel to the axis direction of the bubble removing ring 7, and the outer wall of the piston ring 8 abuts against the inner wall of the bubble removing ring 7, so as to facilitate the negative pressure suction; the operating member is arranged on the bubble removing ring 7, the operating member is used to drive the piston ring 8 to move, and the isolation assembly 9 is arranged on the bottom wall of the bubble removing ring 7, and the isolation assembly 9 is used for the gas to pass through and block the glue.

[0051] When the cable 4 and the connector 5 are installed in the tool body 201, the debubbling ring 7 is installed on the upper end of the two tool bodies 201 by the cooperation of the connecting lug 22 and the bolt, so that the debubbling ring 7 is concentric with the glue pouring cavity 3. At this time, the piston ring 8 is in an initial state, and the initial state of the piston ring 8 is close to the isolation assembly 9. Then, one-time glue pouring is performed into the glue pouring cavity 3. Since the bubbles generated by the glue input by the output nozzle 15 under the action of gravity are easy to accumulate at the circumferential edge position at the top of the glue pouring cavity 3, that is, the position corresponding to the isolation assembly 9. After the glue pouring is completed, the tool body 201 is vibrated by the vibrator installed on the outer wall of the tool body 201 to sufficiently discharge the bubbles in the glue upward. Then, the piston ring 8 is driven to move away from the isolation assembly 9 by the operating member. Since the piston ring 8 and the debubbling ring 7 are sealed, a negative pressure suction is generated in the glue pouring cavity 3. The bubbles enter the debubbling ring 7 through the isolation assembly 9, and the isolation assembly 9 blocks the glue, thereby reducing the bubbles in the glue and helping to ensure the connection reliability of the cable 4 and the connector 5.

[0052] The gas in the debubbling ring 7 is pushed out of the debubbling ring 7 after the glue solidifies, and the debubbling ring 7 is removed from the two tool bodies 201. The piston ring 8 is driven to move towards the isolation assembly 9 by the operating member, that is, the gas is pushed out of the debubbling ring 7, which is convenient for next use.

[0053] Referring to Figure 3 and Figure 5 In order to conveniently drive the piston ring 8 to move, the operating member includes an operating rod 10. The operating rod 10 is symmetrically distributed along the axis of the debubbling ring 7. Both of the operating rods 10 are slidably arranged on the side wall of the debubbling ring 7. The operating rod 10 is L-shaped, and the side wall of the debubbling ring 7 is provided with a strip-shaped hole 23 for sliding cooperation with the operating rod 10. One end of the operating rod 10 is fixedly connected with the piston ring 8, and the other end extends out of the debubbling ring 7 from the corresponding strip-shaped hole 23.

[0054] When it is necessary to drive the piston ring 8 to move away from the isolation assembly 9 to perform suction in the glue pouring cavity 3, the two operating rods 10 are simultaneously turned upward, so that the operating rod 10 lifts the piston ring 8. Since there is friction between the piston ring 8 and the inner wall of the debubbling ring 7, the piston ring 8 is not easy to move under the action of artificial force.

[0055] Referring to Figure 3 and Figure 5In order to facilitate the gas through the barrier colloid, the isolation assembly 9 comprises a micro-channel grid 91 and a breathable film 92, the micro-channel grid 91 is fixed on the bottom wall of the defoaming ring 7 through screws, the micro-channel grid 91 is located below the piston ring 8, and the micro-channel grid 91 is used for gas passing and blocking colloid; specifically, the gap of the micro-channel grid 91 is 0.1-0.3 mm, the breathable film 92 is arranged on one side of the micro-channel grid 91 close to the piston ring 8, and the breathable film 92 is made of expanded polytetrafluoroethylene film; the micro-channel grid 91 is detachably connected with the defoaming ring 7, so that the breathable film 92 can be conveniently replaced.

[0056] When the piston ring 8 moves in the direction away from the glue filling cavity 3 to perform suction, the cooperation of the micro-channel grid 91 and the breathable film 92 can effectively block the colloid and then extract the bubbles, and the breathable film 92 can be effectively protected.

[0057] Reference Figure 3 and Figure 5 In order to facilitate the sealing between the defoaming ring 7 and the tool body 201, the sealing ring 24 is fixedly sleeved on the outer wall of the defoaming ring 7 in the circumferential direction, and the sealing ring 24 is used for abutting against the inner wall of the glue filling cavity 3.

[0058] The implementation principle of the embodiment of the application is as follows: in use, the cable 4 is placed in the cable half-hole 6 between the two tool bodies 201 and extends downward at one end of the glue filling cavity 3, then the connector 5 is connected with the cable 4 and abuts against the bottom wall of the tool body 201, then the two tool bodies 201 are abutted tightly, the two tool bodies 201 are fixed through bolts or screws, then the positions of the cable 4 and the connector 5 are fixed, at this time, the connector 5 seals the bottom wall of the glue filling cavity 3, and the connection position of the cable 4 and the connector 5 is located in the glue filling cavity 3.

[0059] Then the defoaming ring 7 is installed on the upper ends of the two tool bodies 201 through the cooperation of the connecting ears 22 and the bolts, so that the defoaming ring 7 is concentric with the glue filling cavity 3, at this time, the piston ring 8 is in the initial state, and the initial state of the piston ring 8 is abutting against the breathable film 92.

[0060] Then the glue filling tool 2 is placed on the tool placing table 21, so that the center of the defoaming ring 7 is aligned with the output nozzle 15, then the driving member drives the tool placing table 21 to move upward, so that the output nozzle 15 extends into the defoaming ring 7 and overlaps the defoaming ring 7, then the PLC control platform 11 is operated, so that the stirring mechanism in the material barrel 12 stirs the glue in the material barrel 12, to ensure the uniformity of the glue, then the vacuum pump is started, to remove the bubbles in the glue in the material barrel 12, then the metering pump 13 and the first control valve 16 are started to work, the metering pump 13 draws the preset amount of glue in the material barrel 12 into the mixing barrel 14; then the mixing glue is stirred through the stirring mechanism in the mixing barrel 14, then the second control valve 17 is started, so that the mixed colloid enters the glue filling cavity 3 from the output nozzle 15, thereby realizing the glue filling operation.

[0061] The bubbles generated by the glue inputted into the output nozzle 15 under the action of gravity mainly accumulate at the circumferential edge position of the top of the glue filling cavity 3, that is, the position corresponding to the microchannel grid 91. After the glue filling is completed, the vibrator is installed on the outer wall of the tool body 201, and the tool body 201 is vibrated to fully discharge the bubbles in the glue upward. Then, the two operating levers 10 are moved upward to drive the piston ring 8 to move away from the microchannel grid 91. Since the piston ring 8 is sealed with the bubble removing ring 7, a negative pressure suction is generated in the glue filling cavity 3. The bubbles enter the bubble removing ring 7 through the isolation assembly 9, and the microchannel grid 91 and the air permeable film 92 block the glue, thereby helping to reduce the bubbles in the glue in the glue filling cavity 3.

[0062] After the glue solidifies, the bubble removing ring 7 is removed from the two tool bodies 201. The piston ring 8 is driven by the operating member to move towards the isolation assembly 9, so that the gas in the bubble removing ring 7 is pushed out of the bubble removing ring 7, facilitating the next use. Then, the two tool bodies 201 are separated, the glued joint 5 and the connecting cable 4 are taken out, the solidified glue is processed into the required shape, and then a shielding tape is wound outside the glue filling. Then, plastic packaging is performed, so that the cable 4 and the joint 5 are filled and connected, which helps to ensure the connection reliability between the cable 4 and the joint 5.

[0063] The embodiment of the application also discloses a pinhole cable filling and sealing method of a motor train brake control system. The pinhole cable filling and sealing method uses the glue filling device, and further includes the following steps.

[0064] Step 1: The cable 4 and the joint 5 are installed and fixed between the two tool bodies 201, the cable 4 and the joint 5 are kept connected, and the connection position of the cable 4 and the joint 5 is located in the glue filling cavity 3.

[0065] Step 2: The glue filling tool 2 is placed on the tool placing table 21, and the output nozzle 15 of the mixing barrel 14 is inserted into the center of the bubble removing ring 7 and aligned with the glue filling cavity 3 of the glue filling tool 2 by driving the tool placing table 21 to rise.

[0066] Step 3: The glue in the material barrel 12 is stirred by the stirring mechanism in the material barrel 12, and then the glue in the material barrel 12 is degassed by starting the vacuum pump. The preset amount of glue in the material barrel 12 is pumped into the mixing barrel 14 by starting the metering pump 13 and the first control valve 16, wherein the preset amount is the amount of glue input by the operating personnel through the PLC control platform 11.
