Description

Technical Field

[0001] This invention relates to the electrical performance testing of connectors, and more particularly to a connector electrical performance testing device. Background Technology

[0002] After connectors are manufactured, they need to be inspected. Currently, there is no effective automated equipment, and all product processes rely on manual inspection. This purely manual method has obvious drawbacks: (1) It is impossible to perform simultaneous and effective inspections of various process sequences of the product, such as continuity, withstand voltage, alignment, opening size, and long and short needle identification. (2) Due to the lack of automated equipment, various process tests are currently being conducted on different series of power connector products, which involves multiple operators, resulting in low efficiency and low pass rate, making it impossible to effectively determine whether a product is NG or OK. (3) The product's alignment is checked by manually passing it through a grid plate. When there are bent pins or missing pins, the grid plate cannot effectively identify them, and the grid plate method is easy to scratch and scrape off the surface treatment layer of the pins. (4) Automatic rejection and classification of NG products cannot be achieved. Summary of the Invention

[0022] like Figure 1As shown, a connector electrical performance testing device includes a connector carrier 10, which includes a rotating disk 1 and a driving mechanism 4 for driving the rotating disk 1. A plurality of mounting seats 21 are mounted on the rotating disk 1, and a plurality of connector clamping mechanisms 2 are mounted on the mounting seats 21. Along the rotation direction of the rotating disk 1, a continuity testing mechanism 100, a withstand voltage testing mechanism 200, a positioning detection mechanism 300, an opening size detection mechanism 400, and a connector unloading mechanism 500 are sequentially arranged on the outer side of the rotating disk 1. In this embodiment, the continuity testing mechanism 100 is located at a continuity testing station, the withstand voltage testing mechanism 200 is located at a withstand voltage testing station, and the positioning detection mechanism 300... The location is the alignment detection station, the opening size detection mechanism 400 is located at the opening size detection station, the connector unloading mechanism 500 is located at the connector unloading station, the drive mechanism 4 drives the rotary disk 1 to rotate, and the rotary disk 1 drives the connector clamping mechanism 2 to sequentially enter the continuity test station, the withstand voltage test station, the alignment detection station, the opening size detection station and the connector unloading station, so that the connector is tested for continuity performance at the continuity test station, withstand voltage at the withstand voltage test station, alignment at the alignment detection station, and the opening size at the opening size detection station. Finally, the connector is removed at the connector unloading station.

[0023] In this embodiment, as Figure 2 As shown, the connector clamping mechanism 2 includes a clamping base 22, on which a clamping groove 224 for placing the connector is formed. An elastic pressing device 24 is installed on one side wall of the clamping groove 224, and a plurality of ventilation holes 223 are formed on the other side wall of the clamping groove 224. Figure 6As shown, the elastic pressing device 24 includes a limiting guide rod 242, a compression spring 243, and a pressing head 244. The pressing head 244 is located in the clamping groove 224, and a stepped through hole 241 is provided on the groove wall of the clamping groove 224 near the pressing head 244. The limiting guide rod 242 is installed in the stepped through hole 241. The pressing head 244 is detachably connected to the limiting guide rod 242. The compression spring 243 is installed in the stepped through hole 241. The compression spring 243 is fitted on the limiting guide rod 242, and the other end of the compression spring 243 abuts against the pressing head 244. During installation, the connector is placed into the clamping groove 224, and the connector applies a pushing force to the pressing head 244, thereby causing the compression spring 243 to compress. After the compression head 244 moves, it makes room for the connector to be placed in the clamping groove 224. After the compression spring 243 is compressed, it generates an elastic restoring force. After the connector is placed in the clamping groove 224, the compression head 244 applies a pushing force to the connector under the action of the elastic restoring force of the compression spring 243, thereby clamping the connector in the clamping groove 224. During the clamping process, the connector is not affected by air resistance due to the vent hole 223. As a result, one side wall of the connector is in close contact with the compression head 244, and the other side wall of the connector is in close contact with the corresponding side wall of the clamping groove 224, thus ensuring the reliability of the connector clamping.

[0024] The upper and lower sidewalls of the connector may not be on the same plane. Therefore, to ensure the reliability of the connector clamping, in this embodiment, as follows: Figure 2 As shown, the clamping base 22 includes an upper clamping block 221 and a lower clamping block 222. The upper clamping block 221 is mounted on the lower clamping block 222, and both the upper clamping block 221 and the lower clamping block 222 are equipped with elastic pressing devices 24. Both the upper clamping block 221 and the lower clamping block 222 are provided with vent holes 223. Therefore, when the connector is clamped in the clamping groove 224, the upper sidewall of the connector is abutted by the pressing block on the upper clamping block 221. The lower sidewall of the connector is abutted by the pressing block on the clamping block, thereby ensuring the reliability of connector clamping. Moreover, both the upper clamping block 221 and the lower clamping block 222 are provided with ventilation holes 223. Therefore, the connector will not be affected by air resistance during clamping. In this embodiment, the upper clamping block 221 and the lower clamping block 222 are connected by locking screws, and the lower clamping block 222 and the mounting base 21 are also connected by locking screws.

[0025] In this embodiment, as Figure 6As shown, the top of the pressure head 244 is provided with an outwardly flared arc surface 246 or wedge-shaped surface. Therefore, when the connector is placed into the clamping groove 224, after the connector contacts the arc surface 246 or wedge-shaped surface, as the connector moves downward, the arc surface 246 or wedge-shaped surface applies an axial thrust to the pressure block, thereby causing the pressure block to move, so that the connector can be smoothly placed into the clamping groove 224.

[0026] In this embodiment, as Figure 6 As shown, the pressing head 244 and the limiting guide rod 242 are connected by connecting screws 245. Furthermore, a limiting block is provided at the end of the limiting guide rod 242 away from the clamping groove 224. The limiting block cannot pass through the stepped through hole 241. A central threaded hole is provided at the end of the limiting guide rod 242 near the clamping groove 224. A settling hole is provided on the pressing head 244. The connecting screw 245 passes through the settling hole and locks with the stepped through hole 241.

[0027] In this embodiment, as Figure 1 As shown, several mounting bases 21 are evenly distributed on the same circumference, and multiple connector clamping mechanisms 2 are equally spaced in the circumferential direction. Preferably, there are eight mounting bases 21. Therefore, there are three mounting bases 21 between the continuity testing station and the connector unloading station. The location of these three mounting bases 21 is the connector loading station. In this embodiment, the connector is manually loaded, and the connector is installed in the clamping groove 224. Furthermore, the mounting base 21 is an arc-shaped plate, the center of which coincides with the center of the rotating disk 1. Three connector clamping mechanisms 2 are installed on the base 21, and the included angle between two adjacent connector clamping mechanisms 2 is °. Furthermore, three radially extending scale lines are opened on the top of the mounting base 21, and the included angle between two adjacent scale lines is °. When the connector clamping mechanism 2 is installed, the center line of the connector clamping mechanism 2 extends radially, and on the projection surface of the rotating disk 1, the center line of the connector clamping mechanism 2 coincides with the corresponding scale line. Thus, after the rotating disk 1 is driven by the drive device, the carrier can switch between different workstations.

[0028] In this embodiment, as Figure 4 and Figure 5 As shown, the mounting base 21 is mounted on the rotating disk 1 via the quick-locking device 23. The quick-locking device 23 is existing technology, and its working principle and installation structure will not be described in detail. Therefore, when it is necessary to remove the mounting base 21 from the rotating disk 1, it is only necessary to separate the quick-locking device 23. And when it is necessary to mount the mounting base 21 on the rotating disk 1, it is only necessary to reassemble the quick-locking device 23.

[0029] In this embodiment, as Figure 4 and Figure 5As shown, the mounting base 21 has a detection hole 25 corresponding to the connector clamping mechanism 2. The detection hole 25 extends downward and passes through the rotating disk 1. A position detection mechanism 3 corresponding to the detection hole 25 is installed below the rotating disk 1. Further, the position detection mechanism 3 includes a support frame 31. A sensor 32 for detecting the position of the connector clamping mechanism 2 is installed on the support frame 31. Preferably, the sensor 32 is a photoelectric sensor 32. When the rotating disk 1 rotates to the designated position, the sensor 32 can detect whether the connector clamping mechanism 2 is in the corresponding work position.

[0030] In this embodiment, as Figure 7 As shown, the continuity testing mechanism 100 includes an X-axis moving component 101, a Y-axis moving component 102, and a Z-axis moving component 103. The Y-axis moving component 102 is mounted on the X-axis moving component 101 and moves along the X-axis of the X-axis moving component 101. The Z-axis moving component 103 is mounted on the Y-axis moving component 102 and moves along the Y-axis moving component 102. A second probe component 105 is mounted on the sliding plate of the Z-axis moving component 103, and the probe of the second probe component 105 extends in the Z-direction. An X-axis sliding component 106 is mounted on the sliding plate of the Y-axis moving component 102, and a first probe component 104 is mounted on the actuating end of the X-axis sliding component 106. The probe of the first probe component 104 extends in the X-direction and contacts the top probe of the connector. The probe of the second probe component 105 contacts the X-direction probe of the connector. When the rotating disk 1 moves the mounting base 21 to the connector continuity testing station... Then, the X-axis moving assembly 101, Y-axis moving assembly 102, and Z-axis moving assembly 103 operate, causing the second probe assembly 105 to be positioned above the connector, while the first probe assembly 104 is positioned on the outer side of the connector in the radial direction. Then, the Z-axis moving assembly 103 drives the second probe assembly 105 downward, and the probe of the second probe assembly 105 contacts the top contact pin of the connector. The X-axis sliding assembly 106 operates, causing the probe of the first probe assembly 104 to contact the contact pin in the radial direction of the connector, thereby forming a conductive loop between the first probe assembly 104, the connector, and the second probe assembly 105. If a conductive loop is not detected between the first probe assembly 104, the connector, and the second probe assembly 105, it indicates that the connector is defective and should be rejected. If a conductive loop is detected between the first probe assembly 104, the connector, and the second probe assembly 105, it indicates that the connector's conductivity test meets the requirements and it can proceed to the next process test.

[0031] In this embodiment, as Figure 8As shown, the X-axis sliding assembly 106 includes a telescopic cylinder 111, a support plate 112, and a first X-axis sliding seat 113. The support plate 112 is mounted on the sliding plate of the Y-axis moving assembly 102. The telescopic cylinder 111 is mounted on the support plate 112, and a slide rail 114 is mounted on the support plate 112. A slider is mounted on the bottom of the first X-axis sliding seat 113, and a groove is provided on the slider to slide and cooperate with the slide rail 114. The piston rod of the telescopic cylinder 111 is connected to the first X-axis sliding seat 113. The first probe assembly 104 is mounted on the first X-axis sliding seat 113. In use, the telescopic cylinder 111 extends, and the first probe assembly 104 moves along the X-axis, so that the probe on the first probe assembly 104 contacts the X-axis contact pin on the connector, thereby performing a continuity test on the connector.

[0032] In this embodiment, after the connector passes the continuity test, it enters the withstand voltage test station for withstand voltage testing. If the connector fails the continuity test, it will not be tested further until it enters the connector unloading station, where the connector unloading mechanism 500 places the NG connector into the defective product area.

[0033] In this embodiment, as Figure 9 As shown, the withstand voltage testing mechanism 200 includes a support base 201, on which a Y-axis linear module 202 is mounted. A Z-axis linear module 203 is mounted on the sliding plate of the Y-axis linear module 202. A spring length detection component 204 is also mounted on the sliding plate of the Y-axis linear module 202. A probe pressure application component 205 is mounted on the sliding plate of the Z-axis linear module 203. The probe pressure application component 205 is located above the connector clamping mechanism 2. The spring length detection component 204 is located on the outer side of the connector clamping mechanism 2 in the X direction. In use, the spring length detection component 204 is aligned with the connector... The spring contacts adapt to varying spring lengths, thus connecting the connector's spring contacts with the spring length detection component 204. The probes of the probe pressure component 205 contact the connector's contact pins, creating a conductive loop between the spring length detection component 204, the probe pressure component 205, and the connector. The probes on the probe pressure component 205 are connected to an electrical testing machine. When AC voltage is applied, the machine determines whether the connector's pins and internal spring contacts withstand the voltage. If the voltage withstand test fails, the electrical testing machine sends a feedback signal, thus identifying the connector as a defective product.

[0034] In this embodiment, as Figure 10 and Figure 11As shown, the reed length detection assembly 204 includes a mounting plate 211. An X-axis cylinder 212 is mounted at the rear end of the mounting plate 211, and a second X-axis sliding seat 214 is slidably mounted at the front end of the mounting plate 211. The extension rod of the X-axis cylinder 212 is connected to the second X-axis sliding seat 214. A mounting block is mounted on the second X-axis sliding seat 214. Multiple elastic contact heads are slidably mounted within the mounting block, with the front ends of the elastic contact heads protruding from the mounting block. A return spring 234, which applies a forward thrust, is fitted onto the elastic contact head and is located within the mounting block. The rear end of the elastic contact head protrudes from the mounting block, and a limit shaft 232 is provided on the rear end of the elastic contact head protruding from the mounting block. In use, the X-axis cylinder 212 pushes the second X-axis sliding seat 214 to move in the X direction. When the elastic contact head contacts the reed, since the reed's position is not fixed, if the second X-axis sliding seat 214 continues to... Moving forward, the elastic contact head stops moving forward, and the return spring 234 is compressed. In this embodiment, there are two elastic contact heads, namely the first elastic contact head 217 and the second elastic contact head 218. The springs on the connector have different lengths, and the lengths of the springs are not consistent for different models of connectors. Therefore, during use, when one of the elastic contact heads contacts the longer spring first, the second X-axis slide seat 214 continues to move forward until the other elastic contact head contacts the shorter spring and compresses the corresponding return spring 234. Then, the second X-axis slide seat 214 stops moving. At this time, under the action of the return spring 234, the elastic contact head always has a forward pushing force on the corresponding spring, thereby ensuring the reliability of the contact between the elastic contact head and the spring. Moreover, the spring length detection component 204 has a simple structure, is easy to manufacture, and has low manufacturing cost.

[0035] In this embodiment, as Figure 10 and Figure 11As shown, the mounting block includes an upper pressure plate 215, a lower pressure plate 216, and a rear cover plate 231. The lower pressure plate 216 has a lower stepped groove at its top, and the upper pressure plate 215 has an upper stepped groove at its bottom. The front width of the stepped groove is smaller than the rear width. Therefore, the lower and upper stepped grooves form a mounting cavity that is larger at the rear and smaller at the front. The upper pressure plate 215 is mounted on the lower pressure plate 216 with locking screws, and the lower pressure plate 216 is mounted on the mounting plate 211 with locking screws. The rear ends of both the upper and lower pressure plates 215 and 216 are mounted on the rear cover plate 231 with locking screws. The elastic contact head includes a contact head at the front end, a spring sleeve shaft in the middle, and a limiting shaft 232 at the rear end. A return spring 234 is mounted on the spring sleeve shaft, with its front end abutting against the contact head and its rear end abutting against the rear cover plate 231. Furthermore, the contact head has a rectangular structure, and the width and / or height of the contact head... The diameter of the limiting shaft 232 is greater than that of the spring sleeve shaft. The limiting shaft 232 is cylindrical and its diameter is larger than that of the spring sleeve shaft. The limiting shaft 232 and the spring sleeve shaft are connected by threads. During installation, the return spring 234 is installed on the spring sleeve shaft, and the two spring sleeve shafts are placed at the rear end of the lower stepped groove. The contact head is located at the front end of the lower stepped groove. Since the contact head is a rectangular structure, and the width of the front end of the stepped groove matches the sum of the widths of the two contact heads, the two contact heads cannot rotate in the stepped groove. The rear cover plate 231 has a through hole, through which the spring sleeve shaft passes. Then the limiting shaft 232 is threadedly connected to the spring sleeve shaft. By adjusting the depth of the threaded insertion of the limiting shaft 232 and the spring sleeve shaft, the initial deformation of the return spring 234 and the length of the protruding mounting block of the contact head can be adjusted, so that it can contact the springs of various types of connectors.

[0036] In this embodiment, as Figure 10 and Figure 11 As shown, an X-axis slide rail 213 is mounted on the mounting plate 211, and a slider is provided at the bottom of the second X-axis sliding seat 214. The slider has a groove that slides and engages with the X-axis slide rail 213. The engagement of the X-axis slide rail 213 and the groove ensures the straightness of the movement of the mounting plate 211. Furthermore, a fixing seat 219 is also mounted on the mounting plate 211. The fixing seat 219 has a guide hole 233, and the limiting shaft 232 slides and engages within the guide hole 233. The fixing seat 219 is located behind the rear cover plate 231. The engagement of the limiting shaft 232 and the guide hole 233 ensures the straightness of the movement of the elastic contact head. Moreover, when the rear cover plate 231 contacts the fixing seat 219, the mounting plate 211 cannot move backward, thus the fixing seat 219 also has the function of limiting the position of the mounting block.

[0037] In this embodiment, as Figure 9As shown, the probe pressure assembly 205 includes a Z-axis cylinder 206, which is mounted on a sliding plate of the Z-axis linear module 203. A Z-axis sliding seat 207 is also slidably mounted on the sliding plate. A probe seat 208 is mounted on the Z-axis sliding seat 207. The probe seat 208 and the Z-axis sliding seat 207 are connected by screws. The probe seat 208 is existing technology. Therefore, the installation method of the contact needle in the probe seat 208 will not be described in detail.

[0038] The connector rotates to the withstand voltage test station. Then, the Y-axis linear module 202 and the Z-axis linear template operate, moving the probe holder 208 above the connector and positioning the spring length detection component 204 outside the connector. Then, the X-axis cylinder 212 operates, causing the X-axis sliding seat to move forward along the X-axis. The elastic contact head contacts the spring. Because the elastic contact head retracts after contacting the spring, it adapts to the spring length. Furthermore, the elastic contact head is constantly pushed forward along the X-axis by the return spring 234, ensuring reliable contact between the elastic contact head and the spring. Simultaneously, the Z-axis cylinder 206 operates, causing the Z-axis sliding seat 208 to move forward along the X-axis. The probe moves downwards, causing the probe holder 208 to approach the connector, eventually making the probe on the probe holder 208 contact the contact head on the connector. At this time, a conductive circuit is formed between the spring length detection component 204, the probe pressure component 205, and the connector. The probe on the probe pressure component 205 is connected to the electrical testing machine. After applying AC voltage, it is determined whether the connector pins and internal springs can withstand the voltage. If the withstand voltage test fails, the electrical testing machine will send a signal back, thus determining that the connector is a defective product. Defective products will not be further tested until they enter the connector unloading station, where the connector unloading mechanism 500 places the NG connector into the defective product area.

[0039] In this embodiment, after the connector passes the withstand voltage test, the connector enters the alignment detection station. At this time, the alignment detection mechanism 300 detects the alignment of the connector, mainly detecting whether the connector probe is bent or deformed. The alignment detection mechanism 300 includes a Z-axis sliding module and a CCD component mounted on the Z-axis sliding module. Both the Z-axis sliding module and the CCD component are existing technologies, and the mounting of the CCD component on the Z-axis sliding module is also existing technology. Therefore, the structure and working principle of the alignment detection mechanism 300 will not be described in detail.

[0040] In this embodiment, when a connector fails the alignment test, the defective connector will not undergo further testing until it enters the connector unloading station. The connector unloading mechanism 500 places the NG connector into the defective product area. After the connector passes the alignment test, it enters the opening size detection station for opening size detection. The opening size detection mechanism 400 includes an X-axis sliding module and a CCD component mounted on the X-axis sliding module. Both the X-axis sliding module and the CCD component are existing technologies, and mounting the CCD component on the X-axis sliding module is also existing technology. Therefore, the structure and working principle of the opening size detection mechanism 400 will not be described in detail.

[0041] In this embodiment, as Figure 12 As shown, the connector unloading device includes an X / Y / Z three-axis moving frame 501. A Z-axis linear sliding assembly is mounted on the Z-axis moving frame. A clamping robot 502 is mounted on the sliding plate of the Z-axis linear sliding assembly 504. Preferably, the clamping robot 502 is a double-headed clamping cylinder. An air blowing assembly 503 is mounted on the double-headed clamping cylinder. The air blowing assembly 503 faces the connector and blows air onto the connector, thereby achieving air blowing cleaning of the connector. Furthermore, a defective product placement area 505 is installed on one side of the X / Y / Z three-axis moving frame 501, and a good product conveyor line is set on the other side of the X / Y / Z three-axis moving frame 501. 02 After clamping the connector, if the connector is a good product, it is placed on the good product conveyor line; if the connector is a defective product, it is placed in the defective product placement area 505. Furthermore, four areas are set on the defective product placement area 505: one area for products with NG conductivity, one area for products with NG withstand voltage, one area for products with NG alignment, and the last area for products with NG opening size. In this embodiment, the X / Y / Z three-axis moving frame 501, the Z-axis linear sliding assembly 504, the double-headed clamping cylinder, and the air blowing assembly 503 are all existing technologies. Therefore, their specific structures and working principles will not be described in detail.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
