Description

Technical Field

[0001] The present invention relates to the technical field of conduction testing, and in particular to a conduction testing device and a conduction testing method for powering on a tablet. Background Art

[0002] In precision electronic processing and manufacturing, optical component production and testing, and consumer electronic product production and testing, it is necessary to detect the conductivity of characteristic positions of products, such as the conductivity between components and the conductivity between connectors. Currently, a multimeter is used to detect the detection position, and two contact pins need to contact the test points respectively. The operation steps are cumbersome, and the test results are not intuitive, and the detection efficiency is low. The method of checking the conduction state in the prior art is relatively complicated. Since the contacts of the terminals are relatively small, the contacts of the terminals need to be connected at the same time. Very careful operation is required to ensure that two or more contacts are contacted at the same time. Such detection efficiency is very low, and the measurement accuracy is not high, which is prone to test errors.

[0003] Chinese patent number CN214473855U discloses a conduction test device, including a top plate, a first mounting plate and a second mounting plate, a second cylinder is mounted below the first mounting plate, and a flat plate is arranged below the second cylinder, a mounting block is fixed above the second mounting plate, and a flat plate and a nylon plate are mounted above the mounting block, and the nylon plate is located on the inner side of the support block, a guide column is mounted below the top plate, and the guide column is located on the outer side of the spring pin, a guide sleeve is arranged inside the bottom plate, a first cylinder is mounted above the second mounting plate, and one end of the first cylinder is connected to the support plate. The conduction test device is provided with a top plate and a spring pin, when the top plate moves down, the spring pin inside the top plate will press on the surface of the workpiece, the probe installed on the top plate contacts the workpiece terminal, and the current is connected, and the current flows through the spring pin on the top plate through the terminal on the workpiece, and then flows out through the copper inlay pin installed inside the bottom plate, completing the product conduction test.

[0004] Since the above technical solution can only be tested on a single product at a time, the overall testing capacity is still limited by the mode of testing one by one. Each product testing process requires waiting, resulting in a long test time interval, which is difficult to meet the rapid testing needs of large-scale production lines. Secondly, when placing the test product into the testing equipment through manual operation, the staff's hands will enter the downward pressure area inside the testing equipment.

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] See also Figures 1 to 10 As shown, a conduction test equipment includes a safe conduction detection device installed inside a shielding cabinet 5, and the safe conduction detection device includes a multi-section lifting platform 4, a stable docking detection seat 1, a positioning flip seat 2 and a flip fixture 3; the multi-section lifting platform 4 is fixedly installed inside the shielding cabinet 5, and the lifting end of the multi-section lifting platform 4 extends vertically upward; there are multiple stable docking detection seats 1, and they are evenly distributed at the lifting ends of the multi-section lifting platform 4, and the detection end of the stable docking detection seat 1 extends vertically upward; the positioning flip seat 2 is installed on the top of the multi-section lifting platform 4, and the movable end of the positioning flip seat 2 is set directly above the stable docking detection seat 1; there are multiple flip fixtures 3, and they are symmetrically installed on the upper and lower sides of the positioning flip seat 2, and a plurality of limit placement grooves 311 are provided on the flip fixture 3, and the limit placement grooves 311 correspond one-to-one to the detection ends of the stable docking detection seat 1, and the limit placement grooves 311 match the shape of the test product.

[0039] The multi-stage lifting platform 4 is fixedly installed inside the shielding cabinet 5, and its lifting end extends vertically upward to support and move the stable docking detection seat 1 to different working heights. The design of the multi-stage lifting platform 4 allows fine height adjustment to accommodate test objects of different sizes and types.

[0040] There are multiple stable docking detection seats 1, which are evenly spaced and distributed on the lifting end of the multi-stage lifting platform 4. The detection end of each stable docking detection seat 1 is vertically upward, and is used to make physical contact and electrical connection with the test object to perform the test. The design of the stable docking detection seat 1 ensures stability and accuracy when docking with the test object.

[0041] The positioning flip seat 2 is installed on the top of the multi-stage lifting platform 4, and its movable end is located directly above the stable docking detection seat 1. The positioning flip seat 2 flips the flip fixture 3 and the test product thereon from the top to the bottom through a rotating action to realize the loading and unloading of continuous test products.

[0042] There are multiple flip fixtures 3, which are symmetrically installed on the upper and lower sides of the positioning flip seat 2. Each fixture is provided with multiple limit placement grooves 311. The limit placement grooves 311 correspond one-to-one to the detection ends of the stable docking detection seat 1, and the shape matches the test object to ensure the positioning and stability of the test object during the test process.

[0043] A discharge port is provided at the top of the shielding cabinet 5, and a transparent shielding cover 51 and a safety sensor are provided at the discharge port. A detection controller 52 is also installed on the shielding cabinet 5. The discharge port is convenient for the staff to place the test product. A transparent shielding cover 51 and a safety sensor are installed at the discharge port. When the transparent shielding cover 51 is closed in place, the safety sensor sends a signal to allow the test equipment to start. This ensures safety during operation and prevents accidental injuries caused by operational errors. The detection controller 52 is used to monitor and control the operating status of the test equipment, including test progress, test results, etc., so that the staff can grasp the test situation in real time.

[0044] The staff opens the transparent shielding cover 51 and places multiple test products in the limiting placement groove 311 of the flip fixture 3 in sequence. After closing the transparent shielding cover 51, the safety sensor confirms that the shielding cover is closed in place, and the staff starts the positioning flip seat 2. The positioning flip seat 2 drives the flip fixture 3 to rotate, and the test product to be tested is turned to the top of the stable docking detection seat 1, and the tested test product is turned to the top to be taken out. The multi-stage lifting platform 4 rises, so that the stable docking detection seat 1 pre-collides with the test product to be tested, and performs position verification. If the position is correct, the lifting platform continues to rise until the detection end is tightly fitted with the test product, and the power is turned on for testing. During this period, the staff can open the transparent shielding cover 51, place a new test product in the top flip fixture 3, or take out the tested test product. Repeat the above steps to achieve continuous cycle testing, reduce the detection interval time, improve work efficiency, and at the same time avoid direct contact between the hands of the staff and the inside of the test equipment, thereby improving production safety.

[0045] See also Figures 2 to 6 As shown, the stable docking detection seat 1 includes a limit mounting seat 11 installed on the multi-stage lifting platform 4, a limit mounting rail is provided inside the limit mounting seat 11, and mounting rails 112 are provided on both sides of the limit mounting rail. A limit card joint 113 is slidably installed inside the mounting rail 112, a first push spring 111 is installed between the limit card joint 113 and the mounting rail 112, and an interference detection seat 12 is slidably installed inside the limit mounting rail.

[0046] The limit mounting rails provided inside the limit mounting seat 11 are used to guide the sliding insertion of the interference detection seat 12 to ensure that the interference detection seat 12 can move along a predetermined track. The mounting rails 112 are provided on both sides of the limit mounting rails, and a limit clamping joint 113 is slidably installed inside the limit mounting rails. A first push spring 111 is installed between the limit clamping joint 113 and the mounting rail 112, and the elastic force of the spring keeps the limit clamping joint 113 in a clamping state, thereby effectively limiting the position of the interference detection seat 12 in the limit mounting rails and preventing the interference detection seat 12 from moving.

[0047] The interference detection seat 12 is used to dock with the test object and perform a test. When the multi-stage lifting platform 4 lifts the stable docking detection seat 1 to a position in contact with the test object, the interference detection seat 12 will dock and interfere with the test object, thereby performing a corresponding test operation.

[0048] When the interference detection seat 12 fails or needs maintenance, the staff can toggle the limit clamp joint 113 to make it slide and adjust in the installation rail 112, thereby canceling the limit of the interference detection seat 12. Once the limit clamp joint 113 is canceled, the staff can quickly remove the problematic interference detection seat 12 from the limit installation rail and replace or repair it. This not only improves production efficiency, but also ensures the stability and reliability of the test equipment.

[0049] See also Figures 4 to 7 As shown, the interference detection seat 12 includes a limit mounting plate 121, a plurality of limit holes 1211 are provided on the limit mounting plate 121, a pressure detector 124 is installed at the bottom of the limit hole 1211, a plurality of test pins 1212 are also installed on the limit mounting plate 121, a interference tester 122 is installed above the limit mounting plate 121, a sliding guide column is provided at the bottom of the interference tester 122, the sliding guide column is slidably connected to the limit hole 1211, a second push spring 123 is installed between the sliding guide column and the pressure detector 124, and an insertion hole 1221 is also provided on the interference tester 122, and the insertion hole 1221 corresponds one-to-one to the test pin 1212.

[0050] A plurality of limiting holes 1211 are provided on the limiting mounting plate 121, and the bottom of the limiting holes 1211 are equipped with a pressure detector 124 for real-time monitoring of pressure changes. In addition, a plurality of test pins 1212 are fixed on the limiting mounting plate 121 for performing specific test operations. Above the limiting mounting plate 121, a conflict tester 122 is installed, and a sliding guide post is provided at the bottom of the conflict tester 122, and the sliding guide post is slidably connected with the limiting holes 1211, thereby ensuring the stable movement of the conflict tester 122 in the vertical direction. At the same time, a second push spring 123 is installed between the sliding guide post and the pressure detector 124, which provides the conflict tester 122 with appropriate preload and buffering effect. The conflict tester 122 is also provided with a through hole 1221 corresponding to the test pin 1212, which is used to allow the test pin 1212 to pass through during the test.

[0051] During the test, when the multi-stage lifting platform 4 lifts the stable docking test seat 1 to a position in contact with the test product, the interference test tool 122 first interferes with the test product. If the interference test tool 122 can smoothly enter the interior of the test product, it indicates that the test product has been correctly placed in the designated position and subsequent tests can be performed. At this time, the pressure detector 124 monitors the pressure value of the second push spring 123 to ensure that the fit between the interference test tool 122 and the test product is within a normal range.

[0052] If the interference tester 122 is stably fitted with the test object, and the pressure detector 124 does not detect abnormal pressure, the multi-stage lifting platform 4 will continue to drive the interference detection seat 12 to rise. In this process, the second push spring 123 will be compressed, so that the test needle 1212 on the limit mounting plate 121 can smoothly pass through the insertion hole 1221 on the interference tester 122 and directly contact the test object. Subsequently, various performance tests are performed on the test object through the test needle 1212 to complete the entire test process.

[0053] See also Figure 2 , Figure 8 and Fig. 9 As shown, the positioning flip seat 2 includes a fixed mounting frame 21 fixedly mounted inside the shielding cabinet 5, a rotating mounting plate 22 is rotatably mounted on the fixed mounting frame 21, a plurality of positioning docking shafts 23 are provided on the side of the rotating mounting plate 22, a correction positioning device 25 is also installed on the fixed mounting frame 21, and the positioning flip seat 2 also includes a rotating drive 24 for driving the rotating mounting plate 22 to rotate.

[0054] A rotating mounting plate 22 is rotatably mounted on the fixed mounting frame 21, and a plurality of positioning docking shafts 23 are provided on the side of the rotating mounting plate 22. The positioning docking shafts 23 are used to dock with the correction positioning device 25 to ensure stability and accuracy during the flipping process. When the rotating mounting plate 22 is driven by the rotary driver 24 to rotate to a predetermined position, the correction positioning device 25 will immediately intervene to accurately correct and position the positioning docking shafts 23, thereby ensuring the stability and accuracy of the flip fixture 3 during the flipping process.

[0055] See also Figures 1 to 10 As shown, the correction positioning device 25 includes a limiting docking frame 251 slidably mounted on the fixed mounting frame 21, and a plurality of docking sockets 2511 are provided on the limiting docking frame 251, and the docking sockets 2511 correspond one-to-one to the positioning docking shafts 23. The correction positioning device 25 also includes a first linear drive 252 for driving the limiting docking frame 251 to telescopically move.

[0056] When the rotating mounting plate 22 completes the flipping action under the drive of the rotating driver 24 and reaches the predetermined position, the positioning docking shaft 23 moves accordingly. At this time, the first linear driver 252 is started, driving the limited docking frame 251 to slide along the fixed mounting frame 21 and move toward the corresponding positioning docking shaft 23. As the limited docking frame 251 approaches, the docking socket 2511 gradually aligns with and contacts the positioning docking shaft 23 until they are completely nested. The tight fit between the docking socket 2511 and the positioning docking shaft 23 effectively ensures the stability and accuracy of the rotating mounting plate 22 after flipping to the predetermined position, thereby ensuring the position accuracy and stability of the entire flip fixture 3 during the flipping process.

[0057] See also Figure 2 , Figure 8 and Fig.10 As shown, the flip fixture 3 includes a limit placement plate 31 installed on the rotating mounting plate 22, and a plurality of limit placement grooves 311 are provided on the limit placement plate 31. The interior of the limit placement groove 311 is provided with a correction guide block 34, an adsorption plate 33 and a fitting sensor 32. Limit slide rails are also provided on both sides of the limit placement groove 311, and a flip clamping mechanism 36 is installed on the limit slide rails. The limit placement plate 31 is also provided with a plurality of detection indicator lights 35, and the detection indicator lights 35 correspond one by one to the limit placement grooves 311.

[0058] First, the test product is placed in the limiting placement groove 311 on the limiting placement plate 31. The correction guide block 34 inside the limiting placement groove 311 is customized according to the shape of the test product, and is used to guide the test product to be correctly placed in the groove, effectively avoiding the situation of misplacement. When the test product is placed in the limiting placement groove 311, the fitting sensor 32 is immediately activated to sense whether the test product has been correctly placed in the specified position. Ensure the accurate docking of the test product with the detection end. At the same time, the adsorption plate 33 also starts working, and adsorbs the test product placed in the specified position by generating suction. This adsorption force not only helps to maintain the stability of the test product during the flipping process, but also prevents the displacement of the test product due to vibration or external interference.

[0059] After the test object is stably placed and adsorbed, the rotating mounting plate 22 starts to rotate under the drive of the rotating driver 24. At this time, the flipping clamping mechanism 36 is triggered, moves along the limit slide rail, and clamps the test object to ensure that the test object will not fall off or shift during the flipping process.

[0060] During the flipping process, the detection prompt light 35 starts to work. The detection prompt light 35 corresponds to the limit placement slot 311 one by one, and is used to display the test status of the test product at the corresponding position. When the test product is being tested, the corresponding detection prompt light 35 will light up a specific color to remind the staff of the current status of the test product.

[0061] See also Figures 8 to 10 As shown, the flip clamping mechanism 36 includes a plurality of telescopic clamping strips 361 installed in the limiting slide rails, a pushing telescopic rod 362 is provided on the side of the telescopic clamping strip 361, the pushing telescopic rod 362 is slidably connected to the limiting placement plate 31, a pressing ball 3621 is provided at the end of the pushing telescopic rod 362 away from the limiting placement plate 31, a third pushing spring 363 is installed between the pushing telescopic rod 362 and the limiting placement plate 31, a synchronous connecting rod 364 is installed between the pushing telescopic rod 362 and the telescopic clamping strip 361, and the flip clamping mechanism 36 also includes a rotating control disk 365 installed on the side of the fixed mounting frame 21, a resistance surface is provided on the side of the rotating control disk 365, and a release plane 3652 and an extrusion convex surface 3651 are provided on the resistance surface.

[0062] The push telescopic rod 362 is slidably connected to the limit placement plate 31, and a pressing ball 3621 is provided at one end of the push telescopic rod 362 away from the limit placement plate 31 to reduce the friction between the push telescopic rod 362 and the limit placement plate 31. A third push spring 363 is installed between the push telescopic rod 362 and the limit placement plate 31 to provide the necessary reset force. In addition, the push telescopic rod 362 is connected to the telescopic clamping strip 361 through a synchronous connecting rod 364 to ensure the synchronous movement of the two. The flip clamping mechanism 36 also includes a rotating control disk 365 installed on the side of the fixed mounting frame 21, and a contact surface is provided on the side thereof, and a release plane 3652 and an extrusion convex surface 3651 are respectively provided on the contact surface to control the movement state of the push telescopic rod 362.

[0063] In the initial state, when the flip fixture 3 is located above the rotating mounting plate 22, the pressing ball 3621 of the pushing telescopic rod 362 contacts the extrusion convex surface 3651 of the rotating control plate 365, causing the pushing telescopic rod 362 to compress the third pushing spring 363 and maintain the expansion state of the telescopic clamping bar 361 through the synchronous connecting rod 364. At this time, the telescopic clamping bar 361 does not clamp the test product.

[0064] When the test product is correctly placed in the limit placement groove 311 on the limit placement plate 31, and the rotating mounting plate 22 starts to rotate under the drive of the rotating driver 24, the limit placement plate 31 and all components thereon, including the pushing telescopic rod 362, will rotate synchronously. As the pushing telescopic rod 362 is separated from the extrusion convex surface 3651 and rotates to the position of the release plane 3652, the elastic force of the third pushing spring 363 will push the pushing telescopic rod 362 to move toward the rotating control disk 365 until the pressing ball 3621 contacts the release plane 3652. In this process, the movement of the pushing telescopic rod 362 drives the telescopic clamping bar 361 to contract synchronously through the synchronous connecting rod 364, thereby clamping and fixing the test product in the limit placement groove 311. The stability and safety of the test product during the flipping process are ensured, and the displacement of the test product caused by vibration or external force interference is avoided, thereby ensuring the accuracy and reliability of the test.

[0065] See also Figure 2 and Figure 3 As shown, the multi-section lifting platform 4 includes a mounting base plate 41 installed inside the shielding cabinet 5, a plurality of lifting guide columns 42 are installed on the mounting base plate 41, a lifting push plate 43 is installed on the lifting guide columns 42, a second linear drive 44 is also installed on the mounting base plate 41, the output end of the second linear drive 44 is connected to the lifting push plate 43, and a blocking device 45 is installed on the side of the lifting push plate 43.

[0066] A plurality of lifting guide posts 42 are fixed on the mounting base plate 41, and the lifting guide posts 42 provide a stable lifting track for the lifting push plate 43. In addition, a second linear drive 44 is also mounted on the mounting base plate 41, and its output end is directly connected to the lifting push plate 43, and is used to drive the lifting push plate 43 to move vertically accurately along the lifting guide posts 42. In order to ensure the accuracy and stability of the lifting push plate 43 during the movement, a blocking device 45 is also installed on the side of the lifting push plate 43. The blocking device 45 is used to limit the moving range of the lifting push plate 43, ensuring that it can accurately stay at a predetermined position after each lifting operation.

[0067] During operation, when the stable docking test seat 1 needs to be pushed to dock with the test object, the second linear actuator 44 pushes the lifting push plate 43 to rise or fall steadily along the lifting guide column 42. Since there is a fixed connection between the lifting push plate 43 and the stable docking test seat 1, the movement of the lifting push plate 43 directly leads to the synchronous movement of the stable docking test seat 1.

[0068] During the process of the lifting push plate 43 rising, when the lifting push plate 43 reaches a predetermined height, the blocking device 45 limits the further movement of the lifting push plate 43. At this time, the interference tester 122 on the stable docking detection seat 1 will make a preliminary interference with the test product. This is to verify whether the test product has been correctly placed in the designated position. If the interference tester 122 can smoothly enter the interior of the test product, it means that the position of the test product is correct and subsequent test operations can be performed.

[0069] In order to ensure that the fit between the interference tester 122 and the test product is within a normal range, the pressure value of the second push spring 123 is monitored by the pressure detector 124. If the interference tester 122 and the test product are stably fitted, and the pressure detector 124 does not detect abnormal pressure, the blocking device 45 will release the limit on the lifting push plate 43, allowing it to continue to rise. In the process of the lifting push plate 43 continuing to rise, the second push spring 123 will be gradually compressed, thereby pushing the test needle 1212 on the limit mounting plate 121 through the insertion hole 1221 on the interference tester 122 to achieve direct contact with the test product. Multi-stage pressing of the test product is achieved, ensuring good contact between the test needle 1212 and the test product, thereby improving the accuracy and reliability of the test.

[0070] See also Figure 2 and Figure 3 As shown, the blocking device 45 includes a mounting bracket 451 installed inside the shielding cabinet 5, a telescopic blocking frame 452 is slidably mounted on the mounting bracket 451, a third linear drive 453 is also mounted on the mounting bracket 451, and the output of the third linear drive 453 is connected to the telescopic blocking frame 452.

[0071] In the working process, the third linear actuator 453 is responsible for driving the telescopic blocking frame 452 to perform precise telescopic movement. When the lifting push plate 43 moves to a predetermined height along the lifting guide column 42, the third linear actuator 453 is activated to drive the telescopic blocking frame 452 to extend to block the further movement of the lifting push plate 43. This operation ensures that the lifting push plate 43 and the stable docking detection seat 1 connected thereto can accurately stay at the predetermined position, thereby achieving a preliminary interference test.

[0072] During the interference test, if the interference tester 122 is stably attached to the test object and the pressure detector 124 does not detect abnormal pressure, the third linear actuator 453 is activated again to drive the telescopic blocking frame 452 to retract and release the limit on the lifting push plate 43. At this time, the lifting push plate 43 can continue to move along the lifting guide column 42 to perform subsequent testing operations.

[0073] A conduction test method for a tablet powered on using a conduction test device comprises the following steps:

[0074] S1. Place a plurality of tablets 6 to be tested into the limiting placement slots 311 of the flip fixture 3 accurately in a predetermined order, ensuring that each tablet 6 is stably and accurately positioned at a predetermined position.

[0075] S2. Subsequently, the positioning flip seat 2 is started to drive the flip fixture 3 to perform precise rotation.

[0076] S3. By rotating the flip fixture 3, the tablet 6 to be tested is accurately turned to the top of the stable docking detection seat 1 to ensure that the relative position between the tablet 6 and the stable docking detection seat 1 is accurate. At the same time, the tablet 6 that has completed the test is turned to the top position of the flip fixture 3 to facilitate subsequent removal.

[0077] S4, control the multi-stage lifting platform 4 to rise, so that the stable docking detection seat 1 approaches and pre-contacts the flat plate 6 to be tested, and performs position verification. If the verification result shows that the position of the flat plate 6 is correct, continue to control the lifting platform to rise until the detection end is tightly fitted with the flat plate 6, and then start the power-on test program.

[0078] S5. While the power-on test is in progress, the staff can continue to place a new panel 6 to be tested at the top of the flip fixture 3, or take out the panel 6 that has completed the test. After the panel 6 is replaced, steps S1 to S4 are repeated to achieve a continuous cycle of the test process to improve the test efficiency.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
