Description

Technical Field

[0001] The utility model relates to the technical field of gluing tools, in particular to a split-type heating gluing nozzle. Background Art

[0002] One of the important components of automated gluing equipment is the gluing nozzle, which enables the glue in the glue barrel or gluing equipment to flow out and be applied to the parts on the workpiece.

[0003] In the prior art, there are different styles of glue coating nozzles according to different needs, but most of the current glue coating nozzles have no more functions except discharging glue, and are not suitable for the actual complex production environment. Due to the small internal space of the glue coating nozzle, it is easy to get clogged. In cold weather, the glue is easy to flow poorly due to external environmental factors such as low temperature and glue solidification, resulting in interruption of flow and clogging of the glue coating nozzle. Regular replacement or maintenance is required. Therefore, some glue coating nozzles with heating functions have appeared in the prior art. However, the current glue coating nozzles basically adopt an integral structure. Due to different glue coating requirements, the glue coating nozzle is required to discharge glue of different diameters. When adjusting the diameter of the glue discharging from the glue coating nozzle, the entire glue coating nozzle needs to be replaced, which results in the need to prepare many glue coating nozzles, resulting in increased costs. Utility Model Content

[0004] The purpose of the utility model is to provide a split-type heating glue coating nozzle, which solves the problem in the prior art that when adjusting the glue coating diameter, the integrated glue coating nozzle can only be replaced as a whole, resulting in increased replacement costs.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A split-type heated glue coating nozzle comprises an inner tube, one end of which is provided with a connector for connecting to a glue injection pipeline, and the other end is detachably connected to a glue coating nozzle tip, an outer tube is sleeved on the outer wall of the inner tube, and a heating element and a temperature sensor are installed in the outer tube.

[0007] A further technical solution is that one end of the glue coating nozzle tip is provided with a glue outlet, the outer wall of the other end is provided with an external thread, and the inner wall of the inner tube away from the connector end is provided with an internal thread matching the external thread.

[0008] A further technical solution is that a screw ring is provided on the outer wall of the glue coating nozzle tip, and two opposite sides of the screw ring are both provided with planes.

[0009] A further technical solution is that a first mounting hole and a second mounting hole are provided along the length direction of the outer tube at one end of the outer tube facing the connector, the heating element is installed in the first mounting hole, and the temperature sensor is installed in the second mounting hole.

[0010] A further technical solution is that a fixing threaded hole is provided between the first mounting hole and the second mounting hole at one end of the outer tube facing the connector.

[0011] A further technical solution is that a mounting groove is provided at one end of the outer tube facing the connector, the mounting groove is connected to the outer wall of the outer tube, and the first mounting hole, the second mounting hole and the fixing threaded hole are all provided at the bottom of the mounting groove.

[0012] A further technical solution is that the outer tube is provided with reserved holes that pass through both ends.

[0013] A further technical solution is that the outer tube is sleeved on the outer wall of the inner tube through a locking screw, and a locking screw hole is provided on the side wall of the outer tube that passes through the inside and outside. The locking screw thread is matched and installed in the locking screw hole, and the locking screw and the outer wall of the inner tube are connected by top contact.

[0014] A further technical solution is that a guiding slope is provided on the inner wall edge of the outer tube facing the connecting head.

[0015] Compared with the prior art, the present invention has at least one of the following beneficial effects: 1. The gluing nozzle tip and the inner tube are detachably connected, so when the glue discharge diameter needs to be adjusted, the gluing nozzle tip of different specifications can be replaced without replacing the entire gluing nozzle, thereby reducing costs; 2. By providing a heating element, the glue liquid in the inner tube can be heated to prevent the glue liquid from solidifying in the inner tube due to temperature drop, causing blockage of the inner tube; 3. By providing a temperature sensor, the temperature of the inner tube can be monitored, and any abnormality in the heating element can be discovered in time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Figures 1 to 3 Shown is an embodiment of the present utility model.

[0022] Example 1:

[0023] like Figure 1 As shown, a split-type heated glue coating nozzle comprises an inner tube 1, one end of the inner tube 1 is provided with a connector 2 for connecting to a glue injection pipeline, the other end is detachably connected to a glue coating nozzle tip 3, an outer tube 4 is sleeved on the outer wall of the inner tube 1, and a heating element 5 and a temperature sensor 6 are installed in the outer tube 4. The glue coating nozzle tip 3 and the inner tube 1 are detachably connected, so when it is necessary to adjust the glue discharge diameter, it is sufficient to replace the glue coating nozzle tip 3 of different specifications without replacing the entire glue coating nozzle, thereby reducing costs. By providing the heating element 5, the glue liquid in the inner tube 1 can be heated to prevent the glue liquid from solidifying in the inner tube 1 due to the decrease in temperature, causing the inner tube 1 to be blocked. By providing the temperature sensor 6, the temperature of the inner tube 1 can be monitored, and when an abnormality occurs in the heating element 5, it can be discovered in time.

[0024] Example 2:

[0025] like Figure 3 As shown, based on Example 1, one end of the gluing nozzle tip 3 is provided with a glue outlet 7, and the outer wall of the other end is provided with an external thread 8. The inner wall of the inner tube 1 at the end away from the connector 2 is provided with an internal thread 9 that matches the external thread 8. The connection between the external thread 8 and the internal thread 9 allows the gluing nozzle tip 3 to be stably mounted on one end of the inner tube 1, and the external thread 8 and the internal thread 9 provide a good sealing effect, and facilitate disassembly and installation. It is only necessary to prepare multiple gluing nozzle tips 3 with different glue outlet 7 diameters.

[0026] A screw ring 10 is provided on the outer wall of the gluing nozzle tip 3, and two opposite sides of the screw ring 10 are provided with flat surfaces 11. With the help of the flat surfaces 11, the screw ring 10 can be clamped with an external tool, and then the screw ring 10 is rotated to drive the gluing nozzle tip 3 to rotate as a whole, thereby screwing the external thread 8 into the inner tube 1.

[0027] Example 3:

[0028] like Figure 1 、 2As shown, based on the previous embodiment, a first mounting hole 12 and a second mounting hole 13 are provided along the length of the outer tube 4 at one end of the outer tube 4 facing the connector 2. The heater 5 is mounted in the first mounting hole 12, and the temperature sensor 6 is mounted in the second mounting hole 13. The provision of the first mounting hole 12 and the second mounting hole 13 allows the heater 5 and the temperature sensor 6 to be stably fixed in the outer tube 4. The heater 5 can be an electric heating rod. The heat generated by the electric heating rod is transferred to the glue liquid in the inner tube 1 by heat conduction between the outer tube 4 and the inner tube 1, thereby maintaining the glue liquid at a designed temperature, such as 35°C or 40°C.

[0029] A threaded fixing hole 14 is provided at the end of the outer tube 4 facing the connector 2, between the first mounting hole 12 and the second mounting hole 13. The threaded fixing hole 14 allows for the installation of a number of fixtures. After the heater 5 and temperature sensor 6 are installed in the first mounting hole 12 and the second mounting hole 13, their respective wires will pass through the openings. To prevent the wires of the heater 5 and temperature sensor 6 from becoming disjointed, the wires are secured together by a fixture, or fixed to the wall of the outer tube 4, thereby organizing the wires. The fixture can be any conventional method as required.

[0030] The outer tube 4 is provided with a recessed mounting groove 15 at one end thereof facing the connector 2. The mounting groove 15 is connected to the outer wall of the outer tube 4. The first mounting hole 12, the second mounting hole 13 and the fixing threaded hole 14 are all provided at the bottom of the mounting groove 15. By providing the mounting groove 15, as Figure 1 As shown, the openings of the first mounting hole 12 and the second mounting hole 13 will not be located at the end of the outer tube 4, so they will not be blocked by the connector 2, and the wires can pass through the openings normally.

[0031] The outer tube 4 is provided with a reserved hole 16 running through both ends. By providing the reserved hole 16, other sensors or tools can be installed in the reserved hole 16, such as a visual sensor or a distance sensor, and the entire gluing nozzle can be installed on a robotic arm for use to achieve automated gluing.

[0032] The outer tube 4 is fitted onto the outer wall of the inner tube 1 via locking screws 17. A locking screw hole 18 is provided on the sidewall of the outer tube 4, extending through both the inner and outer sides. Locking screws 17 are threadedly mounted within locking screw holes 18, and the locking screws 17 and the outer wall of the inner tube 1 are in contact with each other. The provision of locking screws 17 and locking screw holes 18 ensures a stable attachment of the outer tube 4 to the outer wall of the inner tube 1. For secure installation, two locking screws 17 and locking screw holes 18 are typically provided.

[0033] The inner wall edge of the outer tube 4 facing the connector 2 is provided with a guide bevel 19. By providing the guide bevel 19, when the outer tube 4 is installed on the inner and outer outer walls, the end of the inner tube 1 away from the connector 2 is inserted into the outer tube 4 from the position of the guide bevel 19. The guide bevel 19 can guide the inner tube 1 to be smoothly inserted into the outer tube 4.

[0034] Although the present invention has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and implementations may be devised by those skilled in the art that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the present disclosure, the drawings, and the claims, various variations and modifications may be made to the components and / or layout of the subject combination arrangement.
