DETAILED DESCRIPTION

[0029] The utility model will be described in detail below with reference to the accompanying drawings:

[0030] Example: As shown in the attached Figures 1 to 3As shown, the automatic sealing assembly structure of the electric heating tube includes a positioning cylinder 1, a fixed shelf 2, a first rotary drive cylinder 3, a dispensing valve 4, a flange positioning plate 5, a clamping jaw 6, a first cylinder shaft 7, a first rotating shaft 8, a double-tube forked needle 9, a translation cylinder 10, a horizontal slide rail 11, a second rotary drive cylinder 12, a second cylinder shaft 13, a second rotating shaft 14, a pressing block 15, a clamping cylinder 16, a motor 17, a motor shaft 18, a coupling 19, a driving shaft 20, a dispensing push cylinder 21, a glue barrel cylinder 22, a glue barrel 23, a propulsion cylinder 24, a rotating seat 25, a product 26, a first bearing seat 27, a second bearing seat 28, a clamping jaw seat 29, an equipment platform 30, a sliding plate 31, and a vertical slide rail 32.

[0031] Reference Figure 1 , 2 Four workstations are arranged in sequence along the horizontal direction on the equipment platform 30, namely a loading station, a first glue dispensing station, a second glue dispensing station and an assembly station.

[0032] The clamping jaw 6 is driven by the clamping jaw driving mechanism and is used to clamp the product 26 so that the product 26 passes through the four stations of the equipment platform 30 in sequence. Further, the clamping jaw driving mechanism includes a horizontal slide rail 11 arranged in the horizontal direction of the equipment platform 30, a sliding plate 31 is slidably arranged on the horizontal slide rail 11, and the sliding plate 31 is driven by the translation cylinder 10. A vertical slide rail 32 is arranged on the sliding plate 31 perpendicular to the horizontal slide rail 11, and a clamping jaw seat 29 is slidably arranged on the vertical slide rail 32, and the clamping jaw seat 29 is driven by the propulsion cylinder 24. Further, four clamping jaws 6 (corresponding to four stations) are arranged on the clamping jaw seat 29, and when the clamping jaw seat 29 moves horizontally along the equipment platform 30, the clamping jaw 6 clamps the product 26 and transports it from the previous station to the next station.

[0033] A loading and turning mechanism is provided at the loading station. After the product 26 is placed in the loading station, the loading and turning mechanism drives the product 26 to turn 90° (i.e., perpendicular to the surface of the equipment platform 30). The loading and turning mechanism includes a positioning cylinder 1, a fixed shelf 2, and a first rotary drive cylinder 3. The first rotary drive cylinder 3 drives the first rotating shaft 8 to rotate through a first transmission assembly. A flange positioning plate 5 is provided at the other end of the first rotating shaft 8. After the product 26 is loaded, it is placed on the fixed shelf 2. The positioning cylinder 1 pushes the product 26 to be positioned on the flange positioning plate 5. The flange positioning plate 5 rotates synchronously with the first rotating shaft 8 to achieve a 90° flip of the product 26. The first transmission assembly includes a first cylinder shaft 7 connected to the first rotary drive cylinder 3, and the first rotary shaft 8 is supported on the equipment platform 30 through the first bearing seat 27. Preferably, the other end of the first cylinder shaft 7 is connected to a swing rod, and the other end of the swing rod is hinged to a swing block. The first rotary shaft 8 is fixedly connected to the swing block. When the first cylinder shaft 7 moves in an extension and contraction manner, the swing rod is synchronously driven, and the swing block is then driven to rotate by the swing rod, thereby driving the first rotary shaft 8 to rotate, thereby converting the linear motion of the first cylinder shaft 7 into the rotational motion of the first rotary shaft 8.

[0034] The first dispensing station is provided with a first dispensing mechanism, which can drive the product 26 to rotate and dispense glue to one nozzle of the product 26. The second dispensing station is provided with a second dispensing mechanism, which can drive the product 26 to rotate and dispense glue to another nozzle of the product 26. Figure 3 As shown, the first dispensing mechanism and the second dispensing mechanism both include a dispensing cylinder 21, a dispensing valve 4 and a rotating seat 25. The dispensing cylinder 21 is supported on the equipment platform 30 by a bracket. The dispensing cylinder 21 can drive the dispensing valve 4 to move toward the nozzle of the product 26. Preferably, the dispensing cylinder 21 and the dispensing valve 4 are both arranged obliquely. The clamp 6 places the product 26 on the corresponding rotating seat 25, and the rotating seat 25 can drive the product 26 to rotate around the outlet of the dispensing valve 4 to achieve dispensing. Preferably, as Figure 1 As shown, the rotating seat 25 is driven by the driving shaft 20 , and a motor 17 is installed on the equipment platform 30 below the rotating seat 25 . The motor 17 drives the driving shaft 20 to rotate through the motor shaft 18 and the coupling 19 .

[0035] Preferably, a glue barrel 23 is provided on the equipment platform 30, and the glue barrel 23 is connected to the glue dispensing valve 4 of the first glue dispensing mechanism and the second glue dispensing mechanism through a pipeline, and a glue barrel cylinder 22 is installed on the glue barrel 23 to control the glue dispensing of the glue barrel 23. The glue storage capacity of the glue barrel 23 is more than 50 times that of a single glue, which can greatly reduce the frequency of glue replacement and improve production efficiency. Furthermore, a double-tube bifurcated needle 9 is installed at the outlet of the glue dispensing valve 4, and the glue sealing efficiency is higher, and the full-circle glue sealing can be completed by rotating 180°. The glue barrel cylinder 22 and the glue dispensing valve 4 adopt conventional structures available on the market.

[0036] The assembly station is provided with a flipping sealing mechanism, which can drive the product 26 to flip back (i.e., return to a state parallel to the surface of the equipment platform 30), and press the rubber pad pre-installed on the product 26 against the pipe mouth of the product 26. The flipping sealing mechanism includes a second rotary drive cylinder 12 and a pressing cylinder 16. The second rotary drive cylinder 12 drives the second rotary shaft 14 to rotate through the second transmission assembly. A flange positioning plate 5 is provided at the other end of the second rotary shaft 14. The clamp 6 places the product 26 on the flange positioning plate 5, and then drives the flange positioning plate 5 and the product 26 to flip 90 degrees through the second rotary drive cylinder 12. The pressing cylinder 16 can drive the pressing block 15 to press the rubber pad of the product 26 after the product 26 flips. The second transmission assembly includes a second cylinder shaft 13 connected to the second rotary drive cylinder 12, and the second rotary shaft 14 is supported on the equipment platform 30 through a second bearing seat 28. Preferably, the other end of the second cylinder shaft 13 is connected to a swing rod, and the other end of the swing rod is hinged to a swing block, and the second rotary shaft 14 is fixedly connected to the swing block. When the second cylinder shaft 13 telescopes, it synchronously drives the swing rod, and the swing rod drives the swing block to rotate, thereby driving the second rotary shaft 14 to rotate, converting the linear motion of the second cylinder shaft 13 into the rotational motion of the second rotary shaft 14.

[0037] The working process of the utility model is as follows: during operation, the operator places a product 26 to be processed on the fixed shelf 2, the positioning cylinder 1 pushes the product 26 to the flange positioning plate 5, and the first rotary drive cylinder 3 drives the first rotary shaft 8 to rotate through the first cylinder shaft 7, so that the flange positioning plate 5 (product) is flipped 90°. Then the translation cylinder 10 and the propulsion cylinder 24 drive the clamp 6 to clamp the product 26 to the first dispensing station, and the dispensing push cylinder 21 pushes the double-barreled forked needle 9 on the dispensing valve 4 to move to the dispensing position (i.e., the pipe mouth) of the product 26. The motor 17 connects the motor shaft 18 and the drive shaft 20 through the coupling 19 to drive the rotating seat 25 (product 26) to rotate. At the same time, the glue barrel cylinder 22 controls the glue in the glue barrel 23 to flow out from the double-barreled forked needle 9 to complete the dispensing of one pipe mouth. The clamp 6 clamps the product 26 to the second dispensing station, and repeats the previous step to complete the dispensing of another pipe mouth. The product 26 after dispensing is clamped by the clamp 6 to the assembly station, and the second rotary drive cylinder 12 drives the second rotary shaft 14 to rotate through the second cylinder shaft 13 to realize the flange positioning plate 5 (product 26) flipping 90°, and the clamping cylinder 16 pushes the pressing block 15 to assemble the product 26 (press the rubber pad), and after completion, the clamp 6 clamps the product 26 to the product completion area.

[0038] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
