Description

Technical Field

[0001] This utility model belongs to the field of terminal block testing technology, specifically relating to a precise positioning terminal block testing device. Background Technology

[0002] A precision-positioning terminal block testing device is a precision testing equipment designed for electrical connection terminals. Its core lies in the synergistic effect of mechanical positioning and electrical testing to achieve rapid and accurate testing of terminal blocks. This device typically consists of a positioning mechanism, a drive mechanism, and testing probes. Precision-positioning terminal block testing devices eliminate errors from manual inspection, improving testing efficiency and reliability. They are particularly suitable for batch testing of key parameters such as terminal continuity and crimping quality in wire harness production. This device is widely used in wire harness manufacturing processes in automotive electronics, industrial automation, aerospace, and other fields. It can effectively detect defects such as loose connections, misalignment, and deformation of terminals, ensuring the safe operation of electrical systems. Furthermore, its modular design adapts to different terminal specifications, meeting diverse production needs.

[0003] Existing precision-positioning terminal block inspection devices typically rely on visual inspection modules to accurately measure terminal dimensions and identify surface defects. However, their structural designs generally have limitations. On the one hand, due to the lack of surface pretreatment structures, impurities such as metal dust and oil, common in industrial environments, easily adhere to the terminal surface, interfering with optical imaging during inspection and causing deviations in the identification of defects such as scratches and indentations, even affecting the accuracy of dimensional measurements. On the other hand, in batch inspection scenarios, terminals are prone to obstruction due to stacking or misalignment, especially bottom terminals which may be completely covered by upper layers, preventing the vision system from fully acquiring their image information. These problems not only reduce the reliability of inspection data but also limit the applicability of the equipment in complex production environments, making the practicality of precision-positioning terminal block inspection devices somewhat lacking.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Please see Figure 1-5 This utility model provides a precise positioning terminal detection device, comprising:

[0029] The main body of the detection device 1 and the conveying assembly 2;

[0030] Mounting frame 3 is set on the upper end of conveying component 2. Conveying component 2 passes through the main body 1 of detection device. A drive shaft 4 is rotatably connected inside mounting frame 3.

[0031] Multiple mounting rods 5 are all located on the outside of the drive shaft 4. The multiple mounting rods 5 are arranged in a ring around the central axis of the drive shaft 4. The outer side of the multiple mounting rods 5 is fitted with a matching mounting sleeve 6. Two mounting sleeves 6 located on the same side are provided with the same positioning plate 7.

[0032] Multiple air blowing channels are respectively opened in multiple positioning plates 7, and multiple air exhaust holes 8 are provided through one side of each air blowing channel. An air supply channel is opened in the drive shaft 4.

[0033] Specifically, such as Figure 2 and Figure 5 As shown, multiple mounting rods 5 are all provided with mounting holes that connect to the air supply channel, and multiple mounting sleeves 6 are all provided with air injection holes 9 that connect to the air blowing channel at one end.

[0034] Through its design, the mounting holes in multiple mounting rods 5 and the air injection holes 9 at one end of multiple mounting sleeves 6 allow air in the air supply channel to enter the air blowing channel in the positioning plate 7 and be discharged through multiple exhaust holes 8, which can conveniently and comprehensively clean dust and impurities on the surface of the wiring terminals, ensuring the accuracy of their appearance data inspection.

[0035] Specifically, such as Figure 2 As shown, an air pump 10 is provided on one side of the mounting frame 3. The air pump 10 is existing technology and will not be described in detail here. The air outlet of the air pump 10 is located in the air supply channel and is slidably connected to the inner wall of the air supply channel. It can also introduce air into the air supply channel without affecting the rotation of the drive shaft 4.

[0036] Specifically, such as Figure 2 As shown, a drive motor 11 is provided on one side of the mounting frame 3. The drive motor 11 is existing technology and will not be described in detail here. One end of the drive shaft 4 passes through one side of the mounting frame 3 and is set on the output end of the drive motor 11. The output end of the drive motor 11 will drive the drive shaft 4 to rotate.

[0037] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, a fixed plate 12 is provided between two mounting rods 5 on the same side, and a limiting plate 13 is provided between two mounting sleeves 6 on the same side. Multiple fixed plates 12 and multiple limiting plates 13 enable the two mounting rods 5 and two mounting sleeves 6 on the same side to move synchronously.

[0038] Specifically, such as Figure 2 and Figure 3 As shown, multiple fixing plates 12 are each provided with threaded rods 14, and multiple limiting plates 13 are each provided with threaded holes that are adapted to the threaded rods 14. The multiple threaded rods 14 pass through the multiple threaded holes and are threadedly connected to the side walls of the threaded holes. By rotating the threaded rods 14, the multiple limiting plates 13 can be moved, thereby moving the multiple mounting sleeves 6 and the multiple positioning plates 7. This allows the multiple positioning plates 7 to adapt to terminals of different sizes, specifications and thicknesses, and can effectively flatten and remove dust from them.

[0039] Example 2:

[0040] Please see Figure 1-5 This utility model provides a precise positioning terminal detection device, comprising:

[0041] The main body of the detection device 1 and the conveying assembly 2;

[0042] Mounting frame 3 is set on the upper end of conveying component 2. Conveying component 2 passes through the main body 1 of detection device. A drive shaft 4 is rotatably connected inside mounting frame 3.

[0043] Multiple mounting rods 5 are all located on the outside of the drive shaft 4. The multiple mounting rods 5 are arranged in a ring around the central axis of the drive shaft 4. The outer side of the multiple mounting rods 5 is fitted with a matching mounting sleeve 6. Two mounting sleeves 6 located on the same side are provided with the same positioning plate 7.

[0044] Multiple air blowing channels are respectively opened in multiple positioning plates 7, and multiple air exhaust holes 8 are provided through one side of each air blowing channel. An air supply channel is opened in the drive shaft 4.

[0045] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, two guide plates 15 are rotatably connected to one side of the mounting frame 3. Both guide plates 15 are inclined. The two inclined guide plates 15 can effectively limit the position of the wiring terminals, ensuring the accuracy of the conveying assembly 2 in conveying them, so that they can be effectively detected by the detection device.

[0046] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, the upper end of the mounting frame 3 is provided with an electric push rod 16. The electric push rod 16 is existing technology and will not be described in detail here. The output end of the electric push rod 16 is provided with a drive plate 17. The bottom ends of the drive plate 17 are provided with guide shafts 18 on both sides. The upper ends of the two guide plates 15 are provided with guide grooves that are adapted to the guide shafts 18. The two guide shafts 18 are located in the two guide grooves respectively and are slidably connected to the side wall of the guide groove.

[0047] With its design, when the electric push rod 16 is started, its output end will drive the drive plate 17 and the two guide shafts 18 to move. With the help of the two guide grooves, the two guide plates 15 can be adjusted to different angles to adapt to the conveying trajectory of different specifications of terminal blocks, so that the precise positioning terminal block detection device can be more efficient and compatible with diverse production scenarios.

[0048] See Figure 1-5 When using the precise positioning terminal block testing device, the terminal block is first placed on the conveying assembly 2. The conveying assembly 2 will move the terminal block into the main body 1 of the testing device. Then, according to the size specifications of the terminal block, multiple threaded rods 14 are rotated. The multiple threaded rods 14 will drive multiple limit plates 13 to move respectively, thereby adjusting the positions of multiple mounting sleeves 6 and multiple positioning plates 7. Then, the air pump 10 and drive motor 11 are started. The air pump 10 will draw outside air into the air delivery channel in the drive shaft 4, and through the mounting holes in the multiple mounting rods 5 and the air injection holes 9 at one end of the multiple mounting sleeves 6, the air is introduced into the multiple positioning plates 7. In the air blowing channel inside, when air enters the air blowing channel, it will be discharged through multiple exhaust holes 8, which can thoroughly and effectively clean the dust and impurities on the surface of the terminal block. When the drive motor 11 starts, its output end will drive the drive shaft 4 to rotate. The drive shaft 4 will drive multiple positioning plates 7 to rotate through multiple mounting rods 5 and multiple mounting sleeves 6. This not only flattens the stacked terminal blocks, ensuring that the main body 1 of the detection device can completely detect each terminal block, but also increases the range of air blowing, improving the cleaning effect of dust and impurities on the surface of the terminal block, thereby ensuring the reliability of the detection data of the accurately positioned terminal block detection device.
