Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and in particular to a terminal identification device. Background Technology

[0002] Automotive terminal blocks are the vital link in automotive signal transmission, playing a crucial role in various automotive functions. For example, car audio systems and horns rely on signal transmission between connecting wires and modules to achieve audio playback or horn operation. Automotive terminal blocks commonly serve as this transmission link to enable these functions. Before leaving the factory, these terminal blocks undergo quality testing. Currently, for small batches of terminal blocks, inspection is typically done manually, which is labor-intensive and inefficient.

[0003] To address the aforementioned shortcomings, existing technologies, such as Chinese Patent No. CN205749326U, disclose a terminal visual inspection device, including a frame, an inspection device, and a feeding device. Both the inspection device and the feeding device are mounted on the frame. The feeding mechanism includes a feeding plate and an adjusting plate. The feeding plate has a feeding channel and an adjusting groove. The adjusting plate is adjustablely mounted on the feeding plate using screws. The inspection device includes a control system and first and second camera mechanisms. The first and second camera mechanisms are electrically connected to the control system to provide feedback detection signals. The first and second camera mechanisms are adjustablely mounted on the frame and positioned on opposite sides of the feeding plate. The advantages are: the visual inspection system software is simple, facilitating user operation during production; different product models can be freely interchanged for inspection without complex re-setting; and it has a data storage function for easy querying and verification.

[0004] During use, the aforementioned terminal visual inspection equipment maintains a relatively stationary state between the camera mechanism and the terminal, resulting in a limited detection range. Furthermore, when identifying wiring terminals, the equipment is prone to displacement due to external impacts, which affects the accuracy and efficiency of the identification process. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a terminal visual recognition and detection device, which solves the problem that terminal misalignment is easily caused by external collisions during the terminal recognition process in the prior art.

The bracket has a height-adjustable sliding frame, on which a scanner and / or camera are mounted. The base has a rotation-angle-adjustable placement platform, on which a clamping mechanism to prevent displacement is provided. The clamping mechanism includes two symmetrically arranged transverse pushing components. Each transverse pushing component has a clamping plate at its end, and telescopic springs are provided between the clamping plates and the transverse pushing components on both sides. This clamping mechanism can clamp the terminal blocks on the placement platform, effectively preventing displacement due to collision and improving recognition efficiency.

[0007] Further preferably, the lateral pushing assembly includes a mounting base disposed on a placement platform, a horizontally positioned electric push rod on the mounting base, a housing at the telescopic end of the electric push rod, and a clamping plate floatingly connected to the housing. The lateral pushing assembly allows for the rapid clamping of terminals of different specifications.

[0008] Further preferably, the housing is provided with a guide groove, and the rear of the clamping plate is provided with a guide rod, which is located in the guide groove. The end of the guide rod is provided with a positioning plate that cooperates with the guide groove, and a buffer spring is provided between the positioning plate and the bottom of the guide groove. The above structure realizes the floating connection between the clamping plate and the housing, reducing the wear on the surface of the terminal block during the clamping process.

[0009] In a further preferred embodiment, a limiting plate is slidably provided at the front of the guide rod, the limiting plate is located behind the clamping plate, and the telescopic spring is located between the limiting plate and the housing and on both sides of the guide rod; ensuring that the clamping plate stably clamps the wiring terminals.

[0010] Preferably, the bottom of the placement platform is equipped with a drive shaft, which is rotatably connected to the base via bearing components. The drive shaft is also connected to a drive motor housed within the base via a transmission pair. The drive motor drives the drive shaft to rotate via the transmission pair, thereby rotating the placement platform and allowing for adjustment of the platform's rotation angle.

[0011] More preferably, the transmission pair includes a driven pulley disposed on the transmission shaft and a driving pulley disposed on the output shaft of the drive motor, wherein the driven pulley is connected to the driving pulley via a belt.

[0012] More preferably, the transmission pair includes a driven gear disposed on the transmission shaft and a driving gear disposed on the output shaft of the drive motor, wherein the driven gear meshes with the driving gear.

[0013] In a further preferred embodiment, the support is a gantry frame, with vertically arranged guide rails on both sides of the gantry frame and sliders on both sides of the sliding frame, the sliders slidingly engaging with the guide rails; a vertically arranged telescopic rod is provided on the upper part of the gantry frame, and the telescopic end of the telescopic rod is connected to the sliding frame.

[0014] In a further preferred embodiment, the guide rail is provided with a dovetail guide groove, and the slider is a dovetail block, with the dovetail block slidingly engaging with the dovetail guide groove; ensuring a stable and smooth connection between the slider and the guide rail.

[0015] Further preferably, the bracket is equipped with a supplementary light corresponding to the placement platform; the light in the scanning area of ​​the scanner is adjusted to ensure the clarity and accuracy of the scan.

[0016] The beneficial effects of this utility model are as follows: (1) This utility model uses a separate telescopic rod to drive the sliding frame to adjust the height of the scanner and / or camera, so that it is at a suitable height, transmits the identified image information to the built-in database, and uses the built-in terminal identification function to identify the scanned terminal. This height adjustment method is quick and easy to operate, and the horizontality of the scanner and / or camera is easy to ensure; and the clamping mechanism set on the placement table is used to clamp the terminal, avoiding the displacement caused by external collision when identifying the terminal.

[0017] (2) The present invention uses a rotating angle adjustable placement platform to drive the transmission shaft to rotate through a drive motor and transmission pair, thereby driving the placement platform to rotate. This makes it easy to adjust the rotation angle of the placement platform relative to the base, change the detection position of the wiring terminal relative to the scanner and / or camera, facilitate multi-angle recognition of the wiring terminal, and improve the recognition efficiency.

[0018] (3) The clamping mechanism of this utility model drives the housing to move through an electric push rod. The housing drives the clamping plate to clamp the terminal block placed on the placement table. In addition, the buffer spring is used to relieve the friction generated by clamping and reduce the wear on the surface of the terminal block. The clamping plate is limited by the limiting plate to prevent the clamping plate from shifting.

[0019] (4) The sliding block is limited by the guide rail between the sliding frame and the support in this utility model to prevent the sliding block from falling off, thereby increasing the stability of the recognition device. The sliding block drives the scanner to move, making it easy to adjust the height of the scanner. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1, such as Figure 1 As shown, a terminal block visual recognition and detection device includes a base 1, which serves as the support structure for the entire device. A bracket 2 is fixedly mounted on the base 1, and a height-adjustable sliding frame 3 is provided on the bracket 2. A scanner 7 and / or a camera are mounted on the sliding frame 3. The scanner can be an infrared scanner. The sliding frame moves up and down relative to the bracket to adjust the height of the scanner, ensuring that the scanner 7 is at a suitable height. The recognized image information is transmitted to a built-in database, and the scanned terminal block is identified using the built-in terminal block recognition function. In this embodiment, the base 1 is provided with a rotation-angle-adjustable placement platform 13, meaning the placement platform can rotate relative to the base, causing the terminal block on the placement platform to rotate, so that the scanner can perform omnidirectional scanning and recognition of the terminal block. The placement platform 13 is provided with a clamping mechanism to prevent displacement; the clamping mechanism is used to clamp the terminal block, preventing displacement caused by external collisions during terminal block recognition.

[0030] The clamping mechanism in this embodiment includes two symmetrically arranged lateral pushing components. Each lateral pushing component has a clamping plate 19 at its end. The two lateral pushing components move relative to each other, pushing the clamping plate to clamp the terminal block and ensure its stability. Telescopic springs 21 are provided between the clamping plate 19 and the corresponding lateral pushing components on both sides. These springs buffer the impact force of the clamping plate on the terminal block and prevent the clamping plate from being biased, further improving the clamping stability of the terminal block.

[0031] Example 2: A visual recognition and detection device for wiring terminals, such as... Figure 2 As shown, this embodiment further optimizes upon embodiment 1. In this embodiment, the lateral pushing component includes a mounting base 14 disposed on the placement platform 13, serving as a support structure for the lateral pushing component. The mounting base 14 is equipped with a horizontally positioned electric push rod 16. The telescopic end of the electric push rod 16 is provided with a housing 17, which is a connector between the clamping plate and the electric push rod. The clamping plate 19 is floatingly connected to the housing 17, buffering the friction generated during clamping and reducing wear on the terminal block surface. The electric push pump drives the electric push rod to move the housing 17, which in turn drives the clamping plate to clamp the terminal blocks placed on the placement platform.

[0032] like Figure 5 , 6 As shown, the specific structure of the floating connection between the clamping plate 19 and the housing 17 in this embodiment is as follows: the housing 17 is provided with a guide groove 22, and the rear of the clamping plate 19 is provided with a guide rod 23. The guide rod 23 is located in the guide groove 22 and plays a guiding role for the movement of the clamping plate. The end of the guide rod 23 is provided with a positioning plate 24 that cooperates with the guide groove 22. A buffer spring 18 is provided between the positioning plate 24 and the bottom of the guide groove 22. The buffer spring buffers the impact force between the clamping plate and the terminal block, relieves the friction generated by clamping, and reduces the wear on the surface of the terminal block.

[0033] In this embodiment, a limiting plate 20 is slidably provided at the front of the guide rod 23. The limiting plate is movably mounted on the guide rod and is located behind the clamping plate 19. The telescopic spring 21 is located between the limiting plate 20 and the housing 17 and on both sides of the guide rod 23. The limiting plate limits the clamping plate, and the telescopic spring prevents the clamping plate from shifting.

[0034] like Figure 4As shown, in this embodiment, a drive shaft 15 is fixedly installed at the bottom of the placement platform 13. The drive shaft 15 is rotatably connected to the base 1 via bearing components, and the drive shaft 15 is connected to the drive motor 8 installed in the base 1 via a transmission pair; the drive motor can be a stepper motor. The transmission pair includes a driven pulley 12 installed on the drive shaft 15 and a driving pulley 10 installed on the output shaft 9 of the drive motor 8. The driven pulley 12 is connected to the driving pulley 10 via a belt 11. When the stepper motor operates, it drives the output shaft 9 to rotate, which in turn drives the driving pulley 10 to rotate. The driving pulley 10 then drives the belt 11 to rotate, which in turn drives the driven pulley 12 and the drive shaft 15 to rotate. The drive shaft 15 then drives the placement platform 13 to rotate, facilitating the adjustment of the detection and identification position of the terminals on the placement platform 13. This allows the scanner and / or camera installed on the bracket 2 to perform multi-angle identification of the terminals, improving identification efficiency.

[0035] Example 3: A visual recognition and detection device for wiring terminals. This example is a further optimization of Example 1. The difference between this example and Example 2 is as follows: Figure 7 As shown, in this embodiment, the transmission pair includes a driven gear 32 mounted on the transmission shaft 15 and a driving gear 30 mounted on the output shaft 9 of the drive motor 8. The driven gear 32 meshes with the driving gear 30. The drive motor 8 is a stepper motor. The drive motor drives the driven gear to rotate through the driving gear, which in turn drives the transmission shaft 15 to rotate. The transmission shaft 15 then drives the placement platform 13 to rotate, facilitating the adjustment of the detection and identification position of the terminals on the placement platform 13. This allows the scanner and / or camera mounted on the bracket 2 to perform multi-angle identification of the terminals, improving identification efficiency.

[0036] like Figure 3 As shown, in this embodiment, the support 2 is a gantry frame, with vertically arranged guide rails 6 on both sides of the gantry frame, and sliders 5 on both sides of the sliding frame 3. The sliders 5 are slidably engaged with the guide rails 6. A vertically arranged telescopic rod 4 is provided on the upper part of the gantry frame, and the telescopic end of the telescopic rod 4 is connected to the sliding frame 3. The telescopic rod can be a hydraulic telescopic rod or a pneumatic telescopic rod. When the telescopic rod extends downward, it drives the sliding frame to move downward; when the telescopic rod retracts, it drives the sliding frame to move upward. A dovetail guide groove is provided on the guide rail 6, and the slider 5 is a dovetail block. The dovetail block is slidably engaged with the dovetail guide groove. This ensures that the slider block can slide along the guide rail while also limiting the slider block 5 to prevent it from falling off, thus increasing the stability of the identification device.

[0037] In this embodiment, the bracket 2 is equipped with a supplementary light 25 corresponding to the placement platform 13; the supplementary light adjusts the light in the scanning area of ​​the scanner to ensure the clarity and accuracy of the scan.
