Description

Technical Field

[0001] This utility model relates to the field of temperature sensor manufacturing technology, and in particular to a positioning device for a temperature sensor dispensing equipment. Background Technology

[0002] A temperature transducer is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety of types. They can be broadly classified into two categories based on their measurement method: contact and non-contact. Based on the characteristics of their sensor materials and electronic components, they are further divided into resistance temperature detectors (RTDs) and thermocouples.

[0003] In the process of producing temperature sensors, companies inject adhesive into the plastic probe housing using dispensing equipment. Then, they insert the sensor chip and its solder joint with the wires into the probe housing, followed by air drying and curing of the adhesive. This allows the adhesive to effectively fix and seal the sensor chip and its solder joint with the wires. However, in actual production, because the adhesive is often dispensed in batches, cables can easily interfere with the normal dispensing process, increasing the time and effort required for workers and resulting in low efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a positioning device for a temperature sensor dispensing equipment, thereby solving the problems mentioned in the background section.

[0005] A positioning device for a temperature sensor dispensing equipment includes a base and a positioning mechanism mounted on the base. The positioning mechanism includes an angle adjustment component and a clamping component. The angle adjustment component includes a placement platform, an electric cylinder, a guide rail, a toothed plate, a gear, and a swing arm. The placement platform is mounted on the top of the base. The electric cylinder, the guide rail, and the swing arm are all mounted at both ends of the placement platform. There are two sets of guide rails, which are placed opposite each other on both sides of the electric cylinder. There are two sets of swing arms, which are arranged in pairs on the outside of two adjacent guide rails and are rotatably mounted on the placement platform. The bottom side of the toothed plate is fixedly connected to the output end of the electric cylinder and moves up and down along the guide rail. The gear is fixed to the lower end of the swing arm and meshes with the side of the toothed plate for transmission.

[0006] The clamping assembly is mounted on the angle adjustment assembly and includes a clamping part one, a movable frame, and a clamping part two.

[0007] The first clamping part is vertically swinging and fixed to the top of the swinging arm. The movable frame passes through the first clamping part. The second clamping part consists of multiple evenly arranged parts installed on the inner side of one side of the movable frame, and is configured to correspond one-to-one with the multiple clamping slots opened on the first clamping part. The second electric cylinder is installed on the first clamping part, and its output end is fixedly connected to the movable frame.

[0008] By adopting the above technical solution, the device facilitates the placement of the probe housing and wires, constrains the wires to avoid excessive and untidy wires affecting the glue application, and allows for quick and easy removal after glue application.

[0009] When the swing arm is in a vertical position, the clamping part is in a horizontal position, and the clamping groove is set to correspond to the placement groove at the bottom of the placement platform.

[0010] By adopting the above technical solution, after the probe shell and wires are coated with glue, the movable frame is set as a rectangular frame structure and is set parallel to the clamping part.

[0011] The above technical solution facilitates the clamping of the wire.

[0012] The clamping part two is composed of a cylinder and an arc-shaped plate. The arc-shaped plate is fixed to the movable frame by the cylinder, and the width of the clamping part two is adapted to the width of the clamping groove.

[0013] By adopting the above technical solution, the conductor can be stably clamped.

[0014] The central axis of the toothed plate and the guide rails on both sides is on the same vertical section as the central axis of the placement platform.

[0015] By adopting the above technical solution, the swing angle of the swing arm is guaranteed to be consistent.

[0016] The beneficial effects of the positioning device for the temperature sensor dispensing equipment of this utility model are:

[0017] The temperature sensor probe housing is placed in the placement slot. The wire is then passed between the clamping slot and the second clamping part, and vertically placed in the corresponding probe housing. The second electric cylinder pulls the movable frame, clamping the wire in the clamping slot via the second clamping part. Then, the first electric cylinder pulls the gear plate upwards along the guide rail. The gear plate drives the gears on both sides to rotate, which in turn drives the swing arm to swing. The wire will synchronously follow the first clamping part in shifting at a certain angle. This device facilitates the placement of the probe housing and wire, constrains the wire, prevents excessive and uneven wires from affecting glue application, allows adjustment of the wire position for easy glue application, and after glue application, the wire can be returned to its original position to allow the glue to cure. The wire's angle will not change.

[0018] It affects the connection between the wires and the probe housing, while also allowing for quick and easy removal. Attached Figure Description

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Referring to Figures 1-2, a positioning device for a temperature sensor dispensing equipment includes a base 1 and a positioning mechanism mounted on the base 1. The positioning mechanism includes an angle adjustment component and a clamping component. The angle adjustment component includes a placement platform 2, an electric cylinder 3, a guide rail 4, a toothed plate 5, a gear 6, and a swing arm 7. The placement platform 2 is mounted on the top of the base 1. The electric cylinder 3, the guide rail 4, and the swing arm 7 are all mounted at both ends of the placement platform 2. There are two sets of guide rails 4, which are placed opposite each other on both sides of the electric cylinder 3. There are two sets of swing arms 7, which are arranged on the outside of two adjacent guide rails 4 and are rotatably mounted on the placement platform 2. The bottom side of the toothed plate 5 is fixedly connected to the output end of the electric cylinder 3 and moves up and down along the guide rail 4. The gear 6 is fixed to the lower end of the swing arm 7 and meshes with the side of the toothed plate 5 for transmission.

[0024] The clamping assembly is mounted on the angle adjustment assembly and includes a clamping part 8, a movable frame 9, a clamping part 2 10, and an electric cylinder 2 11. The clamping part 8 is set vertically to the swing arm 7 and is fixed to the top of the swing arm 7. The movable frame 9 is set through the clamping part 8. The clamping part 2 10 consists of multiple clamping parts evenly arranged on the inner side of one side of the movable frame 9 and is set one-to-one with the multiple clamping slots 801 opened on the clamping part 8. The electric cylinder 2 11 is mounted on the clamping part 8 and its output end is fixedly connected to the movable frame 9.

[0025] The clamping part 2 10 is composed of a cylinder and an arc-shaped plate. The arc-shaped plate is fixed to the movable frame 9 by the cylinder, and the width of the clamping part 2 10 is adapted to the width of the clamping groove 801. The temperature sensor probe housing is placed in the placement groove 201, and then the wire is passed between the clamping groove 801 and the clamping part 2 10 and placed vertically in the corresponding probe housing. Then, the electric cylinder 2 11 is driven to pull the movable frame 9, so that the wire is clamped in the clamping groove 801 by the clamping part 2 10. Then, the electric cylinder 1 3 is driven to pull the toothed plate 5 to move upward along the guide rail 4. The toothed plate 5 drives the gears 6 on both sides to rotate, and then the gears 6 drive the swing arm 7 to swing. At this time, the wire will synchronously follow the clamping part 1 8 to offset a certain angle (it should be noted that the swing angle of the swing arm 7 can be controlled as needed, preferably controlled at 40 degrees). This allows the external dispensing equipment to control the placement table 2. After the probe housing is filled with glue, drive the electric cylinder 3 in reverse to return the clamping part 8 to its original position. (During this time, check if any wires have come out of the probe housing or if the probe housing is not in the correct position. Adjust it manually if necessary.) Wait for the glue to solidify. (Ultraviolet curing UV glue can be used to speed up the solidification process.) Then drive the electric cylinder 11 in reverse to release the wires from the clamping slot 801. The temperature sensor can then be removed.

[0026] This device facilitates the placement of the probe housing and wires, constrains the wires to prevent them from being too numerous and untidy, which could affect the glue application, and allows for quick and easy removal after glue application.

[0027] When the swing arm 7 is in the vertical position, the clamping part 8 is in the horizontal position. At this time, the clamping groove 801 is set to correspond to the placement groove 201 at the bottom of the placement platform 2. This is so that after the glue is applied, the wire can be restored to the vertical position, ensuring that the wire and the probe housing are stably connected by the glue through curing.

[0028] The movable frame 9 is a rectangular frame structure and is set parallel to the clamping part 8. The movable frame 9 is set as a rectangular frame structure and always remains parallel to the clamping part 8 when driven by the electric cylinder 11, so as to facilitate the adjustment of the clamping part 10 to clamp the wire in the clamping groove 801.

[0029] The central axis of the toothed plate 5 and the guide rails 4 on both sides is on the same vertical section as the central axis of the placement platform 2; the electric cylinder 3 is also located on this vertical section. When the electric cylinder 3 is driven, it can move the toothed plate 5 up and down.

[0030] The gears 6 on both sides rotate, which in turn drives the swing arm 7 to swing at an angle, so that the subsequent dispensing equipment can inject adhesive.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
