Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to an electronic product testing jig. Background Art

[0002] In conventional automated test lines, a handling mechanism (such as a robotic arm or a lead screw module equipped with a fixture) is used to move the products to be tested on the conveyor line one by one to the test fixture for testing. After the test is completed, the handling mechanism is used to move the products from the test fixture back to the conveyor line for delivery. As a result, the efficiency is extremely low when testing large quantities of electronic products. Utility Model Content

[0003] The purpose of the utility model is to provide an electronic product testing jig to solve the technical defects described in the background technology.

[0004] The electronic product testing fixture includes a substrate and a material frame, a support module and a test seat are installed on the substrate, the support module includes a lifting cylinder and a lifting slide located on both sides of the test seat, the lifting cylinder drives a support plate sliding on the lifting slide, the support plate is arranged with a roller group that can be connected to the conveyor line, and an in-position sensor is installed next to the head end of the roller group. The roller group is used to support the two sides of the bottom of the material frame, and a product position for placing the product to be tested is provided in the material frame. The test seat is provided with a conductive sheet. When the lifting cylinder drives the support plate to drive the material frame to descend, the conductive sheet contacts the product to be tested and is energized.

[0005] According to the technical solution, the utility model can achieve the following beneficial effects:

[0006] When the utility model tests the product on the automated test line, the material frame is pushed onto the roller group by utilizing the conveyor line. At this time, the roller group supports the bottom of both sides of the material frame. When the in-position sensor senses that the material frame is pushed to a specific position of the roller group, the lifting cylinder drives the supporting plate to descend, and the supporting plate drives the material frame on the roller group to descend, so that the conductive sheet contacts the product to be tested and is energized for testing. After the test is completed, the lifting cylinder drives the supporting plate to rise and reset to the same level as the conveyor line. At this time, the conductive sheet leaves the product position, and the conveyor line pushes another material frame onto the roller group. The other material frame pushes the original material frame on the roller group to another section of the conveyor line for transportation.

[0007] Therefore, when the conveyor line is conveying a material frame containing a product to be tested, the material frame can complete the inspection by passing through the electronic product inspection jig. There is no need to use a transport mechanism (i.e., a manipulator, a screw module equipped with a fixture) to transport the products to be tested on the conveyor line one by one into the test jig, nor is there a need to use a transport mechanism to transport the tested products back to the conveyor line for delivery. The inspection of the test products on the conveyor line can be completed, thereby improving the inspection efficiency of large quantities of electronic products.

[0008] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0009] In some embodiments, an adjustment port is provided on the side of the material frame, an adjustment screw module is mounted on the support plate, the adjustment screw module drives a shift plate, an insertion cylinder is mounted on the shift plate, and the insertion cylinder drives an inserting plate for inserting into the adjustment port;

[0010] According to the technical solution, after the material frame is pushed onto the roller assembly, the cylinder drive plate is inserted into the adjustment port. After that, the screw module is adjusted to drive the shift plate to move, and the shift plate drives the material frame to move on the roller assembly to adjust the position of the material frame, so that the conductive sheet can be stably aligned with the product to be tested.

[0011] In some embodiments, each support plate is mounted with a fixed cylinder, which drives a clamping plate for clamping and fixing both sides of the material frame;

[0012] According to the technical solution, after the position adjustment of the material frame is completed, the fixed cylinder drives the clamping plate to move closer to the clamping plate on the other support plate to clamp and fix both sides of the material frame, thereby preventing the material frame from shifting when it descends.

[0013] In some embodiments, a product slot is provided at the bottom of the product position, so that when the product to be tested is placed on the product position, a portion of the product to be tested can pass through the product slot and be mounted on the bottom of the material frame to contact the conductive sheet;

[0014] According to the technical solution, after the support plate drives the material frame on the roller assembly to descend, the conductive sheet can be in contact with the contact point or a component of the product to be tested and energized.

[0015] In some embodiments, the test socket is equipped with a support frame and a clamp cylinder, the support frame is provided with a hollow groove, a back plate is installed on the hollow groove to provide support for the product to be tested, the clamp cylinder drives a test clamp, the test clamp passes through the hollow groove and can be close to the back plate to clamp the product to be tested, and the conductive sheet is provided on the test clamp;

[0016] According to the technical solution, after the support plate drives the material frame on the roller group to descend, the back plate supports one side of the product to be tested, and the fixture cylinder drives the test clamp and the back plate to move closer to clamp the product to be tested, so that the conductive sheet can contact the product to be tested more stably and be energized.

[0017] In some embodiments, the conductive sheet is bent and disposed at the end of the test clip, and the conductive sheet is a deformable beryllium copper sheet;

[0018] According to the technical solution, when the test clip and the back plate are brought close together, it is possible to prevent the conductive sheet from exerting excessive pressure on the product and causing damage.

[0019] In some embodiments, a plurality of product positions are provided on the material frame, a fixture slide is installed on the test seat, a driving plate connected to the fixture cylinder slides on the fixture slide, the number of test clamps and back plates corresponds to the number of product positions, and all test clamps are installed on the driving plate;

[0020] According to the technical solution, when the support plate drives each material frame to descend, a large number of products can be inspected at the same time, thereby further improving the inspection efficiency.

[0021] In some embodiments, the driving plate is equipped with a stopper that can contact the side of the support frame;

[0022] According to the technical solution, when the fixture cylinder drives the test clamp and the back plate to move closer together until they can clamp the product to be tested, the limit block contacts the side of the support frame to prevent the test clamp and the back plate from continuing to move closer together and causing damage to the product.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with specific implementation methods and with reference to the accompanying drawings.

[0033] like Figures 1 to 6 As shown, this specific embodiment provides an electronic product testing fixture, which includes a material frame 1 and a substrate 2, and a support module 3 and a test socket 4 are installed on the substrate 2.

[0034] The material frame 1 is provided with several product positions 11 for the products to be tested. The bottom end of the product position 11 is provided with a product slot 12 so that when the product to be tested is placed in the product position 11, a part of the product to be tested can pass through the product slot 12 and be mounted on the bottom of the material frame 1. The side of the material frame 1 is provided with an adjustment port 13.

[0035] A support module 3 is mounted on both sides of the test stand 4. The support module 3 includes a lifting cylinder 31 and a lifting rail 32. The lifting cylinder 31 drives a support plate 33 that slides on the lifting rail 32. The support plate 33 is equipped with a roller assembly 34 that can be connected to the conveyor line. The roller assembly 34 is used to support the bottom two sides of the material frame 1. The support plate 33 is mounted with an in-position sensor 35, an adjustment screw module 36, and a fixed cylinder 37. The in-position sensor 35 is located near the head end of the roller assembly 34. The adjustment screw module 36 drives a shift plate 361. The shift plate 361 is mounted with an insertion cylinder 362. The insertion cylinder 362 drives an insert plate 363 for insertion into the adjustment port 13. The fixed cylinder 37 drives a clamping plate 371 that clamps and fixes the two sides of the material frame 1.

[0036] The test base 4 is equipped with a support frame 41, a fixture cylinder 42, and a fixture slide 43. The support frame 41 has a hollow groove 411, on which a back plate 412 is fixedly mounted to provide support for the product under test. The number of back plates 412 corresponds to the number of product positions 11, and the position and distance between two adjacent back plates 412 correspond to the position and distance between two adjacent product positions 11. A driving plate 44 is sliding on the fixture slide rail 43 and is transmission-connected to the fixture cylinder 42, so that the fixture cylinder 42 can drive the driving plate 44 to slide on the fixture slide rail 43. A test clamp 45 and a limit block 46 are installed on the driving plate 44. The number of test clamps 45 corresponds to the number of product positions 11, and the position distance between two adjacent test clamps 45 corresponds to the position distance between two adjacent product positions 11. The test clamp 45 passes through the empty slot 411 and can be close to the back plate 412. A bent conductive sheet 451 is provided at the end of the test clamp 45. The conductive sheet 451 is a deformable beryllium copper sheet. The conductive sheet 451 is used to contact the product to energize it, and the limit block 46 can contact the side of the support frame 41.

[0037] The following is the working process of the electronic product testing fixture:

[0038] When testing products on the automated test line, several products to be tested are placed in the product position 11 in the material frame 1. A part of the product to be tested can pass through the product slot 12 and be mounted on the bottom of the material frame 1. The part of the product to be tested at the bottom of the material frame 1 is the part that needs to be contacted and energized by the conductive sheet 451. The material frame 1 is pushed onto the roller group 34 using the conveyor line of the automated test line. At this time, the roller group 34 supports the bottom of both sides of the material frame 1; thereafter, the cylinder 362 is inserted to drive the insert plate 363 to be inserted into the adjustment port, and the screw module 36 is adjusted to drive the shift plate 361 to move. The shift plate 361 drives the material frame 1 to move on the roller group 34 to adjust the position of the material frame 1. When the in-position sensor 35 senses that the material frame 1 is moved When the roller group 34 reaches a specific position, the conductive sheet 451 and the back plate 412 are aligned with both sides of the product to be tested; thereafter, the fixing cylinder 37 drives the clamping plate 371 to approach the clamping plate 371 on the other supporting module 3 to clamp and fix both sides of the material frame 1; thereafter, the lifting cylinder 31 drives the supporting plate 33 to descend, and the supporting plate 33 drives the material frame 1 on the roller group 34 to descend. At this time, the conductive sheet 451 and the back plate 412 are located on both sides of the product to be tested, and one side of the product to be tested relies on the back plate 412; thereafter, the clamp cylinder 42 drives the driving plate 44 to slide on the clamp slide rail 43, so that the test clamp 45 and the back plate 412 are approached to clamp the product to be tested. At this time, the conductive sheet 451 is in contact with the product to be tested and energized for testing.

[0039] After the product is tested, the fixture cylinder 42 drives the driving plate 44 to slide upward on the fixture slide rail 43, so that the test clamp 45 moves away from the back plate 412. At this time, the conductive sheet 451 is separated from the product to be tested; thereafter, the lifting cylinder 31 drives the support plate 33 to rise and reset, and the insertion cylinder 362 drives the insert plate 363 to move out of the adjustment port; thereafter, the fixed cylinder 37 drives the clamping plate 371 and the clamping plate 371 on the support module 3 to open to stop clamping the two sides of the material frame 1; thereafter, the conveyor line pushes another material frame 1 onto the roller group 34, and the other material frame 1 pushes the original material frame 1 on the roller group 34 to another section of the conveyor line for transportation.
