[0036] The invention will now be described in detail with reference to the accompanying drawings.

[0037] Example 1

[0038] An electrical characteristic testing mechanism, such as Figure 1 As shown, the device includes a voltage testing unit 4 and a torque measuring unit 5 that work together. The voltage testing unit 4 is used to position the product and ensure that the product pins and test terminals form a stable contact, so as to detect the electrical characteristics of the product. The torque measuring unit 5 is connected to the product on the voltage testing unit 4 by pressing down and screwing it in, so as to collect and adjust the product's rotation torque and angle curve.

[0039] The voltage testing unit 4 is as follows Figure 2 As shown, it includes a measuring platform configured on a ball screw module 40, a fixture base 42 mounted on the measuring platform, a product receiving platform 43 placed on the fixture base 42, and clamping and positioning control components and probe detection control components configured on the front, back, left and right sides of the product receiving platform 43.

[0040] The measuring platform is as follows Figure 2-3As shown, the assembly includes a connecting base plate 411, a measuring base plate 414, and a measuring top plate 416 arranged sequentially from bottom to top. The connecting base plate 411 is fixed to the ball screw module 40 at its lower part. A pressure sensor is mounted on the upper surface of the connecting base plate 411. The measuring base plate 414 is mounted above the connecting base plate 411 via a guide shaft 412 and a linear bearing 413. The measuring top plate 416 is mounted above the measuring base plate 414 via upright plates 415 on both sides. A fixture base 42 is provided at the center of the upper part of the measuring top plate 416, and a product receiving platform 43 is mounted on the fixture base 42.

[0041] like Figure 3-4 As shown, the clamping and positioning control assembly includes a lifting cylinder 441 mounted below the measuring top plate 416 via a cylinder fixing plate, a push arm opening block 442 driven and connected by the lifting cylinder 441, and a pair of elastic push arms 443 opposite to each other and elastically mounted in the product receiving platform 43 via a compression spring 444. The two elastic push arms 443 have upwardly protruding push heads 443a, and the elastic space between the two push heads 443a constitutes the product receiving space of the product receiving platform 43. The push arm opening block 442 pushes against the bottom of the product receiving platform 43 and is adapted to the bottom of the two elastic push arms 443. When the lifting cylinder 441 drives the push arm opening block 442 to lift upward, the push arm opening block 442 will penetrate the channel of the fixture base 42 and push upward simultaneously against the bottom of the two elastic push arms 443, so that the two elastic push arms 443 are relatively far apart. At this time, the receiving space between the push heads 443a of the two elastic push arms 443 increases, thereby facilitating product placement. After the lifting cylinder 441 is reset, the two elastic push arms 443 move in opposite directions under the action of the compression springs 444 on both sides, thereby fixing the product in place.

[0042] like Figure 5As shown, the probe detection control assembly includes a probe measuring plate 455 carrying probes 456, an opening cylinder 451 and a roller drive plate 453 for driving the probe measuring plate 455, and a tension spring 457 for ensuring probe insertion. Two probe measuring plates 455 are arranged opposite each other, slidably mounted on both sides of the product receiving platform 43 above the measuring top plate 416 via guide rails and sliders. Two probes 456 are respectively mounted facing each other on the two probe measuring plates 455 for detecting the product on the product receiving platform 43. The opening cylinder 451 is mounted on the measuring base plate 414 of the measuring platform. It is connected to the roller drive plate 453 via a cylinder push plate 452. The roller drive plate 453 has two outward drive arms, each with a roller 453a mounted at its end. A linear cam 454 is provided on the side of the probe measuring plate 455 that is adapted to the rollers 453a. When the roller drive plate 453 moves, the rollers 453a at the ends of its outward drive arms push against the linear cam 454 on the probe measuring plate 455 and roll and rub against it, thereby driving the probe measuring plate 455 to slide above the measuring top plate 416. One end of the tension spring 457 is fixed to the measuring top plate 416, and the other end is fixed to the probe measuring plate 455.

[0043] In the non-detection free state, the tension spring 457 keeps the probe measuring plate 455 in a predetermined clamping position, at which point the two probes 456 are close to each other.

[0044] When the product needs to be placed on the receiving platform for electrical testing, opening cylinder 451 first moves roller drive plate 453 away from the product receiving platform 43 via cylinder push plate 452. At this time, the rollers 453a on both sides of roller drive plate 453 push the linear cams 454 on probe measuring plates 455 on both sides, causing the probe measuring plates 455 to slide outwards and move away from each other, thus placing the product into the product receiving platform 43. Then, opening cylinder 451 resets roller drive plate 453 via cylinder push plate 452, and the probe measuring plates 455 return to their initial clamping position. At this time, probe 456 will be connected to the product pins.

[0045] The torque measuring unit 5 is positioned on one side of the voltage testing unit 4 and is used in conjunction with the voltage testing unit 4 to achieve torque measurement and adjustment. Figure 6 As shown, its structure includes a support with a vertical plate 50, a lifting assembly disposed on the support, a pulley assembly mounted above the vertical plate 50, and counterweights 51 and screw-in assemblies connected to the left and right sides of the vertical plate 50 by the pulley assembly.

[0046] The lifting assembly includes a motor 511, a cylinder 512, and a push rod 513. The push rod 513 moves up and down along the cylinder 512 under the drive of the motor 511, lifting the screw-in assembly upward to drive it, and resetting downward.

[0047] The pulley assembly includes a pulley frame 521, a pulley block 522, and a steel cable 523 disposed above the upright plate 50. One end of the steel cable 523 is connected to a counterweight 51 located on one side of the upright plate 50, and the other end of the steel cable 523 is connected to a screw-in assembly. The weight of the counterweight 51 is less than the weight of the screw-in assembly on the other side, so that in the initial state, the counterweight 51 is in a high-lifted state, and the screw-in assembly on the other side is in a low-lifted state. Slide rails are provided on both sides of the upright plate 50, and the counterweight 51 and the screw-in assembly are slidably connected to the two sides of the upright plate 50 through sliders.

[0048] The screw-in assembly includes a push plate 531, a pull bracket 532, a rotary motor 533, a connecting block 534, and a rotating head 535. The upper end of the pull bracket 532 is connected to the steel cable 523 of the pulley assembly. The inner side of the pull bracket 532 is slidably connected to the upright plate 50 via a slider guide rail. The connecting block 534 is installed on the outer side of the pull bracket 532. The rotary motor 533 is installed above the connecting block 534, and the rotating head 535, driven by the rotary motor 533, is connected below it. The push plate 531 is installed on one side of the pull bracket 532 and extends through a window in the upright plate 50 to the other side of the upright plate 50 to be adapted to the top rod 513 of the lifting assembly. A tension spring is provided between the pull bracket 532 and the support.

[0049] During operation, the lifting assembly, via motor 511, raises the push rod 513, pushing the push plate 531 of the screw-in assembly. Under the action of the pulley assembly, the screw-in assembly is pulled upwards, while the counterweight 51 on the other side falls. Subsequently, the push rod 513 falls, at which point the counterweight 51 rises, and the screw-in assembly on the other side moves downwards, causing its rotating head 535 to engage with the product and complete torque measurement. During the falling process of the screw-in assembly, a tension spring provides cushioning to reduce the damaging impact on the product. Simultaneously, as the rotating head 535 presses against the product, its downward pressure ultimately causes the measuring base plate 414, under the action of the guide shaft 412 and linear bearing 413, to contact the pressure sensor on the connecting base plate 411, thereby obtaining the screw-in pressure value.

[0050] Example 2

[0051] An automatic detection and adjustment machine, such as Figure 7 As shown, it includes a feeding unit 1, a transfer unit 2, a visual inspection unit 3, an electrical performance testing mechanism, a defective discharge unit 6, and a discharge unit 7. The electrical performance testing mechanism includes a voltage testing unit 4 and a torque measuring unit 5 that work together.

[0052] The structure of each functional unit will be explained in detail below:

[0053] The feeding unit 1 and the discharging unit 7 have the same structure and are symmetrically arranged at the left and right ends of the equipment. This embodiment takes the feeding unit as an example to describe its structural composition in detail:

[0054] like Figure 8-9 As shown, the feeding unit 1 includes a front feeding platform 11 for conveying a material-loaded fixture, a conveying and cross-cutting platform 12 for transporting and transferring the material-loaded fixture, and a return platform 13 for returning an empty fixture. Guide baffles are provided on both sides of the conveyor belts of the front feeding platform 11 and the return platform 13 to ensure the axial positioning accuracy of the fixture. The front feeding platform 11 is equipped with a fixture braking gripper 111 and a photoelectric sensor 112, and its conveyor belt end is connected to the conveying and cross-cutting platform 12. The conveying and cross-cutting platform 12 includes a platform base plate, a first handling component 121 and a cross-cutting component 122 disposed above the platform base plate, and a second handling component 123 and a blocking component 124 disposed below the platform base plate. The return platform 13 is disposed on the other side of the platform base plate and is arranged parallel to the front feeding platform 11.

[0055] The platform base plate has a long through groove located on the extension line of the conveyor belt of the forward delivery platform 11. A fixture baffle is disposed on each side of the long through groove to form a fixture channel for the platform base plate. The blocking assembly 124 is installed below the platform base plate and has a blocking cylinder and a blocking tongue 124a controlled by the cylinder. The blocking tongue 124a corresponds to the position of the long through groove, and when it extends upward, it can block the fixture channel, thereby preventing the current material-carrying fixture from continuing to move forward. The first conveying assembly 121 is used to convey the material-carrying fixture entering the platform base plate. It includes a lifting cylinder mounted on the transverse module and a conveying gripper driven and controlled by the lifting cylinder. The second transport assembly 123 is used to transport the fixture baffle to the cross-cutting station. It includes a lifting cylinder mounted on the transverse module and an ejector pin 123a driven and controlled by the lifting cylinder. The ejector pin 123a is adapted to fit into a slot at the bottom of the fixture to achieve positioning and connection of the fixture. The cross-cutting assembly 122 includes a cross-cutting cylinder and a cross-cutting push plate connected to its output.

[0056] The material-carrying fixture moves along the conveyor belt on the forward delivery platform 11. When the material-carrying fixture enters the conveying and cross-cutting platform 12 from the forward delivery platform 11, the first handling component 121 moves above it and clamps and positions the material-carrying fixture downwards through its handling jaws, and drags it forward to a predetermined position. At the predetermined position, the lifting cylinder of the second handling component 123 drives its ejector pin 123a to pass through the long through groove of the platform bottom plate and insert into and position itself in the slot at the bottom of the material-carrying fixture. Then, the material-carrying fixture is further transported to the picking station. At the station, the products in the material-carrying fixture will be picked up one by one until it is empty. At this time, the cross-cutting component 122 pushes the empty fixture to the return platform 13 for return through its cross-cutting push plate.

[0057] The above process involves two blocking controls. One is on the forward delivery platform 11. When the photoelectric sensor 112 detects that the material-carrying fixture is passing the fixture brake gripper 111, it controls the fixture brake gripper 111 to clamp the material-carrying fixture, preventing it from continuing to move forward and avoiding interference or collision with the preceding fixture. The fixture is released only after it enters the conveying cross-cutting platform 12. The other is the blocking assembly 124 below the conveying cross-cutting platform 12. Its function is to prevent subsequent material-carrying fixtures entering the platform base plate from continuing to move forward. The fixture is released only after it enters the cross-cutting station.

[0058] The transfer unit 2 is as follows Figure 10 As shown, the device includes a transfer plate 21 driven and controlled by a drive module. The transfer plate 21 is equipped with a pneumatic gripper 22 and three vacuum suction cups 23 at predetermined intervals. The pneumatic gripper 22 is used to grip the product from the product fixture and transfer it to the visual inspection station for visual inspection. The vacuum suction cups 23 are used to complete the subsequent suction operation of the product.

[0059] The visual detection unit 3, as shown in Figure 11 As shown, the device includes a flipping assembly 31, an industrial camera 32, and an image processing unit. The flipping assembly 31 is used to perform multi-angle rotation and positioning of the product, and the industrial camera 32 is used to perform visual inspection of the product. The flipping assembly 31 includes a flipping cylinder 311 and a flipping gripper 312 driven and controlled by it. An observation platform 313 controlled by the cylinder is disposed below the flipping gripper 312. The industrial camera is equipped with a ring-shaped auxiliary light source.

[0060] The electrical performance testing mechanism 5 adopts the structure described in Embodiment 1, and will not be repeated here.

[0061] The defective discharge unit 6, as shown in Figure 12As shown, the system includes a pneumatic gripper 61 for defective products, a defective product discharge channel 62, and a slidably mounted defective product box 63. Multiple defective product boxes 63 are provided according to the type of product defect. The pneumatic gripper 61 receives defective products from the moving unit 2 and inserts them into the defective product discharge channel 62 below, ultimately placing them into the corresponding defective product box 63.

[0062] This invention is not limited to the embodiments discussed above. The above description of specific embodiments is intended to describe and illustrate the technical solutions involved in this invention. Obvious modifications, substitutions, or combinations based on the teachings of this invention should also be considered to fall within the protection scope of this invention.
