[0043] like Figure 3 and Figure 4 As shown, the present invention discloses an electronic component detection device 20, which includes: a turntable 30, a plurality of fixtures 40, a performance detection device 50, and a position adjustment drive device 60.

[0044] like Figure 3 and Figure 4 As shown, a plurality of jigs 40 are distributed in a circular array on the edge of the turntable 30 , a performance detection device 50 is located at the bottom of the turntable 30 , and a position adjustment drive device 60 is located at the side of the turntable 30 .

[0045] like Figure 3 and Figure 4 As shown, the performance detection device 50 includes a detection cylinder 51 and a test pin 52 provided at the telescopic end of the detection cylinder 51 , and the detection cylinder 51 drives the test pin 52 to move up and down.

[0046] like Figure 3 and Figure 4 As shown, the position adjustment driving device 60 includes an adjustment cylinder 61 and an adjustment rod body 62 provided at the telescopic end of the adjustment cylinder 61 , and the adjustment cylinder 61 drives the adjustment rod body 62 to move in translation.

[0047] Next, the specific structure of the fixture 40 of the present invention is described:

[0048] like Figure 5 As shown, the fixture 40 includes: a base 100, a translation bearing 200, and a position adjustment assembly 300. The base 100 is fixed on the end surface of the turntable 30, the translation bearing 200 is movably arranged on the base 100, and the position adjustment assembly 300 is used to drive the translation bearing 200 to move linearly back and forth along the horizontal plane.

[0049] like Figure 6 , Figure 7 and Figure 8 As shown, specifically, the position adjustment assembly 300 includes: a driving part 310 , a left adjustment part 320 , and a right adjustment part 330 ; the left adjustment part 320 and the right adjustment part 330 are respectively located at two ends of the translation support 200 .

[0050] like Figure 7 As shown, the left adjustment part 320 includes: a left rotating seat 321, a left fixed column 322, and a left movable column 323. The left rotating seat 321 is rotatably arranged on the base 100, the left fixed column 322 is fixed on the left rotating seat 321, the left movable column 323 is movably arranged on the left rotating seat 321, and a left return spring 324 is arranged between the left fixed column 322 and the left movable column 323.

[0051] like Figure 8As shown, the right adjustment part 330 includes: a right rotating seat 331, a right fixed column 332, and a right movable column 333. The right rotating seat 331 is rotatably arranged on the base 100, the right fixed column 332 is fixed on the right rotating seat 331, the right movable column 333 is movably arranged on the right rotating seat 331, and a right return spring 334 is arranged between the right fixed column 332 and the right movable column 333.

[0052] like Fig. 9 As shown, a left limiting groove 210 and a right limiting groove 220 are respectively formed at two ends of the translation bearing member 200 .

[0053] The driving part 310 is used to drive the left adjustment part 320 and the right adjustment part 330 so that: the left fixed column 322 abuts against the left limiting slot 210 and the right movable column 333 abuts against the right limiting slot 220, or the left movable column 323 abuts against the left limiting slot 210 and the right fixed column 332 abuts against the right limiting slot 220.

[0054] like Figure 6 As shown, specifically, the driving part 310 includes: a main touch rod 311, a left swing arm 312, and a right swing arm 313. The main touch rod 311 is movably arranged on the base 100 through an elastic member 314; one end of the left swing arm 312 is rotatably arranged on the base 100 and is gear-engaged with the left rotating seat 321, and the other end of the left swing arm 312 is pivotally connected to the main touch rod 311; one end of the right swing arm 313 is rotatably arranged on the base 100 and is gear-engaged with the right rotating seat 331, and the other end of the right swing arm 313 is pivotally connected to the main touch rod 311.

[0055] The adjusting cylinder 61 drives the adjusting rod 62 to move in translation, so that the adjusting rod 62 abuts against or separates from the main contact rod 311 .

[0056] Next, the working principle of the electronic component detection device 20 described above is described in conjunction with the fixture 40:

[0057] Place the electronic component 10 to be inspected on the translation carrier 200 on the fixture 40;

[0058] The turntable 30 rotates under the drive of the relevant driving motor, thereby driving the fixture 40 and the electronic components 10 thereon to rotate to the designated position for detection;

[0059] When the electronic component 10 reaches the specified position, the detection cylinder 51 drives the test pin 52 to rise, and the test pin 52 passes through the corresponding through holes of the turntable 30 and the fixture 40 to directly reach the bottom pad 11 of the electronic component 10, thereby realizing the detection of the electrical performance parameters of the current electronic component 10, and then sending the detection data to the control center, which analyzes the detection data to determine whether the current electronic component 10 is qualified;

[0060] After the detection is completed, the detection cylinder 51 drives the test pin 52 to descend and reset, and the turntable 30 continues to rotate;

[0061] Whether to enable the position adjustment drive device 60 is determined according to the current model of the electronic component 10; for example, if the pad 11 is set on the left side of the bottom of the electronic component 10, it is the original state. In this original state, there is no need to enable the position adjustment drive device 60 to adjust the position of the electronic component 10, and the detection cylinder 51 can directly drive the test pin 52 for detection; for another example, if the pad 11 is set on the right side of the bottom of the electronic component 10, it is a non-original state. In this non-original state, the position adjustment drive device 60 needs to be enabled to adjust the position of the electronic component 10. After the position of the electronic component 10 is adjusted, the detection cylinder 51 drives the test pin 52 for detection;

[0062] It should be noted that, when testing the electronic components 10, it is preferred to process the electronic components 10 in batches according to different models, with the pads 11 arranged on the left side of the bottom of the electronic components 10 forming one batch, and the pads 11 arranged on the right side of the bottom of the electronic components 10 forming another batch, so that fast and effective testing can be achieved;

[0063] When the inspection is completed, the robot grabs the translational carrier 200 and the electronic components 10 thereon and transfers them to the next workstation, such as for CCD inspection, laser marking and other operations. The translational carrier 200 is used to provide a stable carrying surface for the electronic components 10, which is conducive to the smooth completion of subsequent processes by the electronic components 10.

[0064] Next, the method of using the jig 40 is described:

[0065] like Fig.11 As shown, in the original state, the translation bearing member 200 is limited between the left adjustment portion 320 and the right adjustment portion 330. In the original state, the left movable column 323 abuts against the left limiting groove 210 and the right fixed column 332 abuts against the right limiting groove 220;

[0066] In the non-original state, the adjustment cylinder 61 drives the adjustment rod body 62 to translate, and the adjustment rod body 62 further drives the main touch rod 311 to move, and the main touch rod 311 drives the left swing arm 312 and the right swing arm 313 to swing, and one end of the left swing arm 312 drives the left rotating seat 321 to rotate through gear meshing, and one end of the right swing arm 313 drives the right rotating seat 331 to rotate through gear meshing;

[0067] The left rotating seat 321 drives the left fixed column 322 and the left movable column 323 thereon to rotate, and the left fixed column 322 and the left movable column 323 exchange positions, so that the left fixed column 322 abuts against the left limiting groove 210, and the left movable column 323 no longer abuts against the left limiting groove 210;

[0068] At the same time, the right rotating seat 331 drives the right fixed column 332 and the right movable column 333 thereon to rotate, and the right fixed column 332 and the right movable column 333 exchange positions, so that the right movable column 333 abuts against the right limiting groove 220, while the right fixed column 332 no longer abuts against the right limiting groove 220;

[0069] It can be seen that the left fixed column 322 and the right fixed column 332 are rigid driving components, while the left movable column 323 and the right movable column 333 are flexible buffer components. Under the drive of the left fixed column 322 of the rigid driving component, the translation bearing component 200 translates to the right, while the right movable column 333 of the flexible buffer component provides a movable space for the translation bearing component 200 to translate to the right.

[0070] When the adjustment cylinder 61 drives the adjustment rod body 62 to reset, the adjustment rod body 62 is separated from the main touch rod 311, and the main touch rod 311 is reset under the elastic force of the elastic member 314, and the main touch rod 311 drives the left swing arm 312 and the right swing arm 313 to reset, and the left swing arm 312 and the right swing arm 313 respectively drive the left rotating seat 321 and the right rotating seat 331 to rotate and reset, so that under the drive of the right fixed column 332 of the rigid driving member, the translation bearing member 200 is translated to the left and reset, and the left movable column 323 of the flexible buffer member provides a movable space for the translation bearing member 200 to translate and reset to the left;

[0071] It can be seen that the left fixed column 322 and the right fixed column 332 are rigid driving parts, which provide a stable and accurate driving force for the translation bearing member 200 to move left and right; and the left movable column 323 and the right movable column 333 are flexible buffer parts, which provide an effective clamping force for the translation bearing member 200 after movement;

[0072] The present invention realizes the translation of the translation carrier 200 and adjusts the position of the electronic component 10 without moving the base 100 by making an effective and low-cost transformation of the fixture 40. At the same time, the structure of the performance detection device 50 does not need to be adjusted. The detection cylinder 51 only needs to simply drive the test pin 52 straight up and down to achieve the purpose of detection. There is no need to set up a complicated manipulator. The simpler the action, the more accurate the contact between the test pin and the pad can be guaranteed.

[0073] like Fig. 9 and Fig.10As shown, in the present invention, the base 100 is provided with a guide limit column 110, and the translation bearing 200 is provided with a guide limit groove 201 that cooperates with the guide limit column 110. In this way, the translation bearing 200 can stably move linearly on the base 100.

[0074] like Fig. 9 As shown, in the present invention, a positioning column 202 is provided on the translation bearing 200. A corresponding through hole is provided on the board surface of the electronic component 10, and the electronic component 10 is fixed on the positioning column 202 through the through hole without shaking.

[0075] It should be noted that in the present invention, the electronic component 10 is arranged on the base 100 through the translation carrier 200. The base 100 is made of wear-resistant steel, while the translation carrier 200 is made of a softer acrylic material, which can better protect the electronic component 10. On the other hand, in the present invention, the position of the electronic component 10 is indirectly adjusted by adjusting the position of the translation carrier 200, which also better protects the electronic component 10 from wear and tear, and can achieve more precise positioning. On the other hand, when the detection is completed, the robot grabs the translation carrier 200 and transfers it together with the electronic component 10 thereon to the next station, such as performing CCD detection, laser marking and other operations. The translation carrier 200 is used to provide a stable bearing surface for the electronic component 10, which is conducive to the electronic component 10 to successfully complete the subsequent processes.

[0076] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, 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 patent of the present invention shall be subject to the attached claims.
