Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature sensor manufacturing technology, and in particular to a quick connection device for a temperature sensor probe. Background Technology
[0002] A temperature sensor is a device that converts temperature signals into measurable electrical signals. It senses temperature changes through a thermistor and is widely used in industrial control, home appliances, and medical fields to achieve temperature monitoring and regulation.
[0003] During the assembly of the temperature sensor probe, the sensing wire must first be manually and precisely inserted into the designated cavity of the metal or plastic housing to ensure a reliable connection between the wire end and the sensitive element. Next, a two-component epoxy resin adhesive is injected inside the housing. This adhesive is characterized by high temperature resistance, strong insulation, and high mechanical strength after curing, which firmly secures the wire and prevents loosening due to vibration. After injection, the probe is placed in a constant temperature oven at 80-120℃ for 1-2 hours to allow the adhesive to fully cure.
[0004] The shortcomings of the existing technical solutions are as follows: First, the glue application process relies on manual control of the glue amount, which may result in excessive glue overflowing and contaminating the casing, or insufficient glue failing to effectively secure the wires, thus reducing product reliability. Second, manual operation is slow, making it difficult to meet the needs of large-scale production, and prolonged repetitive work can easily lead to operational errors due to fatigue, further increasing the defect rate. Utility Model Content

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0028] like Figures 1 to 6As shown in the figure, a quick connection device for temperature sensor probes provided in this embodiment of the present invention includes a lifting platform 1, on which a support plate 5 for placing multiple sets of temperature sensor probe assemblies 6 is mounted. Each set of temperature sensor probe assemblies 6 includes a housing 601 and a sensing wire 602 on the support plate 5. Multiple sets of housing grooves 501 for supporting the housing 601 and wire grooves 502 for supporting the sensing wire 602 are formed on the top of the support plate 5, and each set of housing grooves 501 corresponds to a corresponding wire groove 502, thereby ensuring that the housing 601 and the sensing wire 602 are placed in an orderly manner on the support plate 5. Simultaneously, a support groove is provided on the lifting platform 1 for positioning the support plate 5 to ensure the accuracy of the placement of the support plate 5.
[0029] A support frame 2 is fixedly installed on the rear side of the lifting platform 1, and a pushing mechanism 4 and an injection molding mechanism 3 are fixedly installed on top of the support frame 2. The pushing mechanism 4 is used to push the sensing wire 602 into the housing 601, and the injection molding mechanism 3 is responsible for injecting glue into the housing 601. During operation, the operator only needs to place multiple sets of housings 601 and multiple sets of sensing wires 602 into the corresponding housing grooves 501 and wire grooves 502 on the support plate 5, and then place the support plate 5 into the support groove of the lifting platform 1 for positioning. Afterwards, the pushing mechanism 4 pushes the multiple sets of sensing wires 602 into the housing 601, and the injection molding mechanism 3 injects glue into the housing 601, thus completing the initial assembly of the temperature sensor probe.
[0030] Specifically, the pushing mechanism 4 includes a third automatic telescopic rod 401 fixedly connected to the support frame 2. A connecting plate 402 is fixedly connected to the extended end of the third automatic telescopic rod 401, and multiple sets of pushing blocks 403 are fixedly connected to the bottom of the connecting plate 402. Each set of sensing wires 602 is fixedly connected to a push block 603 that cooperates with the corresponding pushing block 403. During operation, the third automatic telescopic rod 401 drives the connecting plate 402 to move, which in turn drives the pushing blocks 403 to move. The pushing blocks 403 then drive the push blocks 603 to move, ultimately causing the sensing wires 602 to enter the housing 601 along the wire groove 502. Furthermore, the lower ends of the pushing blocks 403 are provided with sloped surfaces on both sides, a structure that facilitates the insertion of the pushing blocks 403 between the sensing wires 602, making the pushing operation smoother.
[0031] The injection molding mechanism 3 includes a first automatic telescopic rod 301 fixedly mounted on the support frame 2. An injection box 302 is fixedly connected to the extended end of the first automatic telescopic rod 301. The injection box 302 is equipped with an injection assembly for injecting adhesive into the housing 601. The movement position of the injection assembly can be controlled by the first automatic telescopic rod 301, thereby realizing the operation of injecting adhesive into the housing 601.
[0032] The injection assembly includes a second automatic telescopic rod 303 fixedly connected to the injection molding box 302. A push plate 304, which slides within the injection molding box 302, is fixedly connected to the output end of the second automatic telescopic rod 303. Multiple sets of injection cylinders 306 are fixedly arranged inside the injection molding box 302. Each set of injection cylinders 306 has a piston column 305 slidingly fitted inside it, and each piston column 305 is fixedly connected to the push plate 304 at its top. Each set of injection cylinders 306 is connected to an injection tube 308 for injecting adhesive into the outer casing 601. During adhesive injection, the second automatic telescopic rod 303 pushes the push plate 304, which in turn moves the piston column 305, thereby quantitatively extruding adhesive from the injection cylinders 306. The adhesive is then injected into the outer casing 601 through the injection tube 308. During the glue injection process, the first automatic telescopic rod 301 continuously drives the injection box 302 to move, which enables the glue to be injected evenly along the outer shell 601, and prevents the glue from coming off with the injection tube 308 when it comes off the outer shell 601.
[0033] The injection box 302 is equipped with delivery pipes 307 for conveying glue, and each set of delivery pipes 307 is connected to the injection cylinder 306. After the glue inside the injection cylinder 306 is injected, the second automatic telescopic rod 303 pulls the push plate 304, and the push plate 304 drives the piston column 305 to move, drawing a certain amount of glue from the delivery pipes 307 to complete the glue replenishment operation.
[0034] In addition, a guide plate 201 is fixedly installed on the support frame 2, which slides and engages with the injection box 302 and the connecting plate 402. The guide plate 201 can maintain the stability of the injection box 302 and the connecting plate 402, ensuring the smoothness of the entire device during operation. The push block 403 is provided with a sliding hole 404 that slides and engages with the injection tube 308. This design allows the injection tube 308 to be aligned with the middle position of the outer shell 601, facilitating accurate glue output and improving the quality and effect of glue injection.
[0035] Working principle: Operators place the outer shells 601 of the temperature sensor probes one by one into the shell grooves 501 on the support plate 5. The shape and size of the shell grooves 501 match the outer shells 601, providing horizontal restraint and ensuring that the outer shells 601 are fixed in position within the shell grooves 501, preventing them from shaking or shifting. Simultaneously, the sensor wires 602 are placed in their corresponding wire grooves 502, which restrain the direction of the sensor wires 602, ensuring they are neatly arranged. The support plate 5, with the temperature sensor probe assemblies 6 in place, is then smoothly placed into the support grooves on the lifting platform 1. The device is then activated, and the lifting platform 1 begins to rise under the drive of the power system.
[0036] The third automatic telescopic rod 401 in the push mechanism 4 starts to work. Its extension end extends linearly in a predetermined direction under the limiting action of its own structure and the support frame 2. The third automatic telescopic rod 401 drives the connecting plate 402 to move, and the push block 403 at the bottom of the connecting plate 402 is inserted between the sensing wires 602.
[0037] The push block 603 fixed on the sensing wire 602 cooperates with the push block 403. When the connecting plate 402 moves, the push block 403, through contact with the push block 603, pushes the sensing wire 602 along the wire groove 502 into the housing 601. The wire groove 502 limits the movement direction of the sensing wire 602, ensuring that the sensing wire 602 can accurately enter the housing 601, realizing the initial assembly of the wire and the housing 601.
[0038] The first automatic telescopic rod 301 in the injection molding mechanism 3 starts to work. Under the limiting action of its own structure and support frame 2, its extended end drives the injection box 302 to move downward, inserting multiple sets of injection tubes 308 into the corresponding outer shell 601.
[0039] Subsequently, the second automatic telescopic rod 303 inside the injection molding box 302 pushes the push plate 304 to move, and the range of motion of the push plate 304 is limited by the inner wall of the injection molding box 302. The push plate 304 drives the piston column 305 to slide inside the injection barrel 306. When the piston column 305 moves, a metered amount of glue is extruded from the injection barrel 306, and the glue is injected into the outer shell 601 through the injection tube 308.
[0040] During the glue injection process, the first automatic telescopic rod 301 continuously drives the injection box 302 to move slowly, ensuring that the glue can be injected evenly along the outer shell 601. When the glue in the injection cylinder 306 reaches the preset injection volume, the limiting device on the second automatic telescopic rod 303 stops it from pushing, completing one glue injection operation.
[0041] After the glue injection is completed, the first automatic telescopic rod 301 drives the injection box 302 to reset. When the glue inside the injection cylinder 306 is finished and needs to be replenished, the second automatic telescopic rod 303 drives the push plate 304 to move upward. The push plate 304 drives the piston column 305 to slide in the opposite direction inside the injection cylinder 306. The delivery pipe 307 inside the injection box 302 is connected to the injection cylinder 306. Under the negative pressure generated by the reverse sliding of the piston column 305, the glue is drawn from the delivery pipe 307 into the injection cylinder 306, completing the glue replenishment.
[0042] The third automatic telescopic rod 401 drives the connecting plate 402 and the push block 403 to reset, causing the push block 403 to disengage from the sensing wire 602 and return to its initial position, thus completing the reset of the push mechanism 4.
[0043] After the pushing mechanism 4 and the injection molding mechanism 3 have both completed their reset, the lifting platform 1 begins to descend under the drive of the power system. At this time, the workers can remove the assembled temperature sensor probe from the support plate 5, completing the entire assembly process.
[0044] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
