Description

Technical Field

[0001] The present invention relates to the technical field of meteorological sensor detection, and in particular to an automatic terminal cross-section detection and analysis device and a system thereof. Background Art

[0002] The weather station can monitor the meteorological data and environmental data area in real time, so a variety of meteorological sensors will be used, such as temperature sensors, humidity sensors, wind speed and direction sensors, air pressure sensors, etc. These meteorological sensors will perform safety quality inspection and analysis on the internal wiring harness terminals during production, thereby improving the detection accuracy and service life of the meteorological sensors during use. Problems encountered in the crimping process of wiring harness terminals include chip jump-out, fan defects, uneven spacing and other defects. Therefore, terminal cross-section detection and analysis has become a key microscopic detection method to confirm the crimping quality. The terminal cross-section detector based on meteorological sensors is a professional equipment, mainly used for detailed detection and analysis of terminal cross-sections. It has a high-precision image acquisition system that can capture the subtle structure of the terminal cross-section.

[0003] There are many technical defects in the use of existing terminal cross-section detectors. First, the current terminal cross-section detector can only detect one wiring harness terminal at a time. Since each group of wiring harness terminals needs to go through multiple steps such as cutting, grinding, and corrosion during detection, the terminal detection efficiency is low and time-consuming. Second, the current grinding and corrosion steps are handled by two independent mechanisms respectively, resulting in a complex structure, insufficient simplicity, and large size of the existing terminal cross-section detector design. Third, when using a detection light source to illuminate the detection cross-section of the terminal, it is easy for external light to refract and interfere, resulting in a light and dark interface in the displayed image, affecting the imaging quality.

[0004] In summary, considering that the existing facilities cannot meet the work requirements, we propose an automatic terminal cross-section detection and analysis device and system. Summary of the invention

[0027] The present invention provides a terminal cross-section automatic detection and analysis device and system through improvement, which has the following significant improvements and advantages compared with the prior art: Start the servo motor to drive the small gear to rotate, and cause the large gear to rotate through meshing deceleration, driving the rotating column to do circular motion around the connecting seat, so that the terminals in each group of clamping sleeves can be subjected to the steps included in the detection process (cutting, grinding and corrosion) in turn, so as to achieve the purpose of batch detection, and start the servo control motor to drive the sprocket on one group of wheel axles to rotate, and make the whole chain plate structure work counterclockwise through the rotation of the rotating chain plate, and pull the terminal transfer tooling to complete all tasks at one time, replacing the transmission screw or cylinder traction structure, reducing the invalid motion path, and improving the degree of automation of detection.

[0028] Starting the first cylinder causes the first telescopic rod to extend outward, pushing the displacement seat to move linearly, and the pushing block and the inclined sliding surface to slide relative to each other, causing the pushing block and the pressure rod to move radially. The pressure rod drives the pressure piece to act on the terminal wiring in the corresponding clamping sleeve to fully press and fix it.

[0029] Start the second cylinder to retract the second telescopic rod, causing the sliding plate to perform limited linear motion. The four groups of driving teeth interact with the five groups of meshing grooves of the driving wheel in turn, causing the driving wheel to flip 180°, so that the driving wheel flips from one group of locking planes to the other group of locking planes, forming a stable self-locking state, improving the stability of the double-sided flip plate, causing the short axis to move around the positioning bearing, and causing the double-sided flip plate in the middle position to flip 180° counterclockwise, automatically switching between the grinding mode and the corrosion mode, integrating the grinding mechanism and the corrosion coating structure, thereby reducing the complexity of the device, reducing the volume, and making the device more scientific and efficient.

[0030] With the help of the power of the second cylinder, during the flipping of the double-sided flip plate, the positions of the two sets of curved liquid storage grooves in the liquid dipping groove are swapped up and down. During the swapping process, the corrosive liquid in the liquid storage groove will flow downward and pass through the sponge core position. The sponge core will absorb part of the corrosive liquid to ensure that the compressed sponge body is fully moistened, thereby achieving the effect of automatic and timely feeding.

When the tube cover is opened, the corrosive liquid can be injected into the curved liquid storage groove 65. Figure 9-11 shown.

[0057] Furthermore, two sets of card slots 90 are symmetrically opened at the edge of the end surface of the substrate 1. The card slots 90 are used to install the external protective cover, which plays a role in dust and touch prevention. Figure 1 shown.

[0058] When the present embodiment is in use, the terminal wiring 91 of several groups of terminals 92 are first sequentially placed into several groups of clamping sleeves 28 of the terminal transfer tooling 20 (the outer ends of the terminals 92 and the clamping sleeves 28 are in contact with each other), and then the first cylinder 30 is started, causing the first telescopic rod 31 to extend outward, pushing the displacement seat 32 to move linearly in the linear limit groove, causing the clamping structure 35 in each group of slide grooves 33 to move relative to each other, and the pushing block 351 and the inclined sliding surface 34 to slide relative to each other, causing the pushing block 351 and the pressure rod 353 to move radially (the reset spring 354 is compressed to generate elastic force), and the pressure rod 353 drives the pressing piece 355 to act on the terminal wiring 91 in the corresponding clamping sleeve 28, fully pressing and fixing it, and several groups of pressing pieces 355 act on the terminal wiring 91 of each clamping sleeve 28 at the same time, respectively, to complete the terminal positioning at one time.

[0059] Then the servo control motor 16 is started to drive the sprocket 11 on one set of the wheel axles 10 to rotate, and the rotating motion of the rotating chain plate 12 makes the entire chain plate structure work counterclockwise, pulling the terminal transfer tooling 20 to move from bottom to top to the position of the cutting wheel 42 that is rotating at high speed, and the terminals 92 in a set of clamping sleeves 28 near the top of the rotating column 23 slowly contact the cutting wheel 42 during the linear motion until they are completely cut off to form a detection section, and then the servo motor 27 is started to drive the small gear 26 to rotate, causing the large gear 25 to rotate through meshing deceleration, driving the rotating column 23 to make a circular motion around the connecting seat 21, so that the terminals 92 in other clamping sleeves 28 contact the cutting wheel 42 in turn during the circular motion (each group of terminals 92 will pass through the cutting area of ​​the cutting wheel 42 on the path of the circular motion), and the cutting is completed in turn.

[0060] At this time, the revolving chain plate 12 continues to drive the terminal transfer tooling 20 with the detection cross section to move linearly to the left until a group of clamping sleeves 28 on the top of the rotating column 23 are aligned with the grinding disk 58 area of ​​the double-sided flip plate 57. At this time, the hydraulic adjustment rod 54 in the hydraulic machine 55 is retracted, causing the adjustment seat 52 to move along the guide track seat 50 (the two groups of T-shaped guide blocks 53 move linearly along the limit track 51 respectively) until the grinding disk 58 and the detection cross section of the terminal 92 contact. At this time, the rotating column 23 is again made to make a circular motion around the connecting seat 21, so that the terminals 92 on each group of clamping sleeves 28 make a circular motion (a faster circular motion) for a period of time. During the movement, they take turns to fully contact and rub with the grinding disk 58 to polish and clean the detection cross section.

[0061] Then, the hydraulic adjustment rod 54 in the hydraulic cylinder 55 is extended to drive the adjustment seat 52 to move outward, so that the double-sided flip plate 57 is away from the terminal transfer tooling 20. At this time, the second cylinder 754 is started to retract the second telescopic rod 755, causing the sliding plate 751 to make a limited linear motion in the sliding limit cavity. During the movement of the sliding plate 751, the four groups of driving teeth 74 interact with the five groups of meshing grooves of the driving wheel 72 in turn (engage in turn to generate a force), causing the driving wheel 72 to flip 180°, so that the driving wheel 72 flips from one group of locking planes 73 to another group of locking planes 73, forming a stable self-locking state, causing the short shaft 70 to move around the positioning bearing 71, and causing the double-sided flip plate 57 in the middle position to flip 180° counterclockwise, so that one side with the arc motion groove 60 is aligned with a group of clamping sleeves 28 on the top of the rotating column 23.

[0062] At this time, the hydraulic adjustment rod 54 in the hydraulic machine 55 is retracted again until the terminal 92 in the clamping sleeve 28 extends into the circular motion groove 60, and the rotating column 23 is again made to make a circular motion around the connecting seat 21, so that each group of terminals 92 on the clamping sleeve 28 makes a circular motion and enters the circular motion groove 60 in turn, and contacts and squeezes the several groups of compressed sponges 62 in the circular motion groove 60, so that the compressed sponges 62 produce corrosive liquid on the surface, and the corrosive liquid is fully contaminated on the detection section of the terminal 92, so as to achieve the purpose of corrosion; wherein, during the flipping of the double-sided flip plate 57, the positions of the two groups of curved liquid storage grooves 65 in the liquid dipping groove 63 are interchanged up and down, and the corrosive liquid in the liquid storage groove will flow downward during the interchange process, and pass through the position of the sponge core 64, and the sponge core 64 will absorb part of the corrosive liquid to ensure that the compressed sponge 62 is fully wetted.

[0063] Then, the revolving chain plate 12 continues to pull the terminal transfer tooling 20 with the detection cross section downward, stops at the position of the detection light source 6, and then uses the high-definition imaging device 3 to image the terminals 92 in a group of clamping sleeves 28 on the top of the rotating column 23, and transmits it to the computer display to form a high-definition picture, and then detects and analyzes it, and uses the morphological algorithm to count the number and distribution of defects, and then allows the rotating column 23 to make a circular motion around the connecting seat 21, so that the terminals 92 on each group of clamping sleeves 28 move to this position in turn for imaging, and the detection of the terminals 92 is completed in batches. Embodiment 2

[0064] On the basis of the first embodiment, when the detection light source 6 is used to illuminate the detection cross section of the terminal 92, it is easy to cause the displayed image to have a light and dark interface due to external light refraction and interference, affecting the imaging quality. In order to solve the above problems, we have the following design, such as Figure 13-15 shown.

[0065] Specifically, two sets of rotating shafts 80 are symmetrically arranged on the outer side of the detection light source 6, and the rotating shafts 80 are fixed by connecting the bearings and the outer shell of the detection light source 6. A mounting bracket 81 is welded to one end of each set of rotating shafts 80 away from the detection light source 6, and a light shield 82 acting on the terminal 92 is connected to the lower end of the two sets of mounting brackets 81. Fig.13 and 14 shown.

[0066] In this embodiment, an adjustment handle 83 is welded to the end of one of the mounting frames 81, and a strip rolling groove 84 is provided on the inner side of the adjustment handle 83. An adjustment hydraulic cylinder 85 is provided obliquely on the side of the light source seat 5. A hydraulic drive rod 87 is provided inside the adjustment hydraulic cylinder 85 and extends downwardly obliquely. A rolling wheel 88 is installed at the lower end of the hydraulic drive rod 87. The rolling wheel 88 is limited to extend into the strip rolling groove 84. The two ends of the strip rolling groove 84 are the starting and ending points of the movement. Fig.14 and 15 shown.

[0067] Furthermore, the upper end of the adjusting hydraulic cylinder 85 is connected to the side of the light source holder 5 via the mounting seat 86 (the connection modes include movable and fixed types, which are designed according to actual conditions).

[0068] When this embodiment is in use, when a group of terminals 92 moves to the top position of the rotating column 23, the adjusting hydraulic cylinder 85 is started, and the hydraulic driving rod 87 is retracted upward, so that the rolling wheel 88 rolls along the strip rolling groove 84 and acts on the adjusting handle 83, pulling the two groups of rotating shafts 80 to rotate around the outside of the detection light source 6, so that the light shielding cover 82 originally on the outside of the terminal 92 rotates to the bottom of the detection light source 6, surrounds the entire terminal 92, and cooperates with the illumination of the detection light source 6 to form a more uniform and concentrated illumination on the detection cross section, thereby improving the imaging quality. Then the hydraulic driving rod 87 is extended downward, and after a series of transmissions, the light shielding cover 82 is rotated back and forth to the outside of the terminal 92 (in an inclined state), so as not to interfere with the circular motion of the terminal 92 on the clamping sleeve 28.
