DETAILED DESCRIPTION

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 An electrical characteristics detection mechanism, such as Figure 1 As shown, it includes a voltage testing unit 4 and a torque measuring unit 5 that cooperate with each other, wherein the voltage testing unit 4 is used to position the product and ensure that the product pins form a firm contact with the test terminals to realize the detection of 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 to collect and adjust the product rotation torque and angle curve.

[0020] The voltage testing unit 4 is as follows Figure 2 As shown, it includes a measuring platform configured on the ball screw module 40, a fixture base 42 installed on the measuring platform, a product receiving platform 43 placed on the fixture base 42, and a clamping positioning control component and a probe detection control component configured on the front, back, left and right sides of the product receiving platform 43.

[0021] The measuring platform is as follows Figure 2-3As shown, it includes, arranged from bottom to top, a connecting base plate 411, a measuring base plate 414, and a measuring top plate 416. The lower portion of the connecting base plate 411 is fixed to the ball screw module 40, and 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 vertical plates 415 on both sides. A jig base 42 is located in the middle above the measuring top plate 416, and a product receiving platform 43 is mounted on the jig base 42.

[0022] like Figure 3-4 As shown, the clamping positioning control assembly includes a lifting cylinder 441 installed below the measuring top plate 416 through 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 arranged opposite to each other and elastically installed in the product receiving platform 43 through 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 accommodating 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 used to adapt to the bottom of the two elastic push arms 443. When the lifting cylinder 441 drives the push arm opening block 442 to lift up, the push arm opening block 442 will pass through the channel of the fixture base 42 and push the bottom of the two elastic push arms 443 upward at the same time, so that the two elastic push arms 443 are relatively separated. At this time, the accommodating space between the push heads 443a of the two elastic push arms 443 is increased, thereby facilitating the placement of products. When the lifting cylinder 441 is reset, the two elastic push arms 443 move toward each other under the action of the compression springs 444 on both sides, thereby clamping the product in place.

[0023] like Figure 5As shown, the probe inspection control assembly includes a probe measurement plate 455 carrying a probe 456, a cylinder 451 for driving the opening of the probe measurement plate 455, a roller drive plate 453, and a tension spring 457 for ensuring the insertion of the probe. Two probe measurement plates 455 are arranged opposite each other, slidably mounted on guide rails on either side of the product receiving platform 43 above the measurement top plate 416. Two probes 456 are mounted on the two probe measurement plates 455, facing each other, to inspect products on the product receiving platform 43. The opening cylinder 451 is mounted on the measurement base plate 414 of the measurement platform and connected to a roller drive plate 453 via a cylinder push plate 452. The roller drive plate 453 has two outward-extending drive arms, each with a roller 453a mounted at its end. A linear cam 454 is provided on the side of the probe measurement plate 455 that mates with the roller 453a. When the roller drive plate 453 is in motion, the rollers 453a at the ends of the outward-extending drive arms push against the linear cam 454 on the probe measurement plate 455, causing rolling friction therewith, thereby driving the probe measurement plate 455 to slide above the measurement top plate 416. A tension spring 457 has one end fixed to the measurement top plate 416 and the other end fixed to the probe measurement plate 455.

[0024] In the non-detection free state, the tension spring 457 keeps the probe measurement plate 455 in a predetermined clamping position, at which time the two probes 456 are close to each other.

[0025] When a product needs to be placed on the receiving platform for electrical testing, the air cylinder 451 is turned on, first using the cylinder push plate 452 to drive the roller drive plate 453 to move away from the product receiving platform 43. At this point, the rollers 453a on either side of the roller drive plate 453 push the linear cams 454 on the probe measurement plates 455 on either side, causing the two probe measurement plates 455 to slide outward and away from each other, placing the product into the product receiving platform 43. The air cylinder 451 is then turned on, using the cylinder push plate 452 to drive the roller drive plate 453 back to its original clamped position. The two probe measurement plates 455 return to their initial clamped position, and the probes 456 engage the product pins.

[0026] The torque measuring unit 5 is configured 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 configured on the support, a pulley assembly installed above the vertical plate 50, and a counterweight block 51 and a screw-in assembly connected to the left and right sides of the vertical plate 50 by the pulley assembly.

[0027] The lifting assembly includes a motor 511, a cylinder 512 and a push rod 513. The push rod 513 is driven by the motor 511 to move up and down along the cylinder 512, lifts up the screw-in assembly to drive it, and resets downward.

[0028] The pulley assembly includes a pulley frame 521, a pulley block 522, and a steel cable 523, which is arranged above the vertical plate 50. One end of the steel cable 523 is connected to a counterweight 51 located on one side of the vertical 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, pulled-up state, and the screw-in assembly on the other side is in a low state. Slide rails are provided on both sides of the vertical plate 50, and the counterweight 51 and the screw-in assembly are slidably connected to the two sides of the vertical plate 50 via sliders.

[0029] The screw-in assembly includes a push plate 531, a pull frame 532, a rotary motor 533, a connecting block 534, and a rotary head 535. The upper end of the pull frame 532 is connected to the pulley assembly's steel cable 523. The inner side of the pull frame 532 is slidably connected to the vertical plate 50 via a slider guide. The outer side of the pull frame 532 is mounted with a connecting block 534. The rotary motor 533 is mounted above the connecting block 534, and the rotary head 535 driven by the rotary motor 533 is connected below. The push plate 531 is mounted on one side of the pull frame 532 and extends through a window in the vertical plate 50 to the other side of the vertical plate 50 to adapt to the jacking assembly's ejector rod 513. A tension spring is provided between the pull frame 532 and the support.

[0030] During operation, the jacking assembly uses the motor 511 to move the push rod 513 upward, pushing the push plate 531 of the screw-in assembly. Under the action of the pulley assembly, the screw-in assembly is pulled upward, and the counterweight 51 on the other side falls. The push rod 513 then falls, and the counterweight 51 immediately rises. The screw-in assembly on the other side moves downward, allowing its rotating head 535 to connect with the product and complete the torque measurement. During the screw-in assembly's fall, the tension spring provides a buffering function to reduce the damage caused by the falling impact on the product. At the same time, when the rotating head 535 presses onto the top of 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.

[0031] Example 2 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 inspection mechanism, a defective discharge unit 6 and a discharge unit 7. The electrical performance inspection mechanism includes a voltage test unit 4 and a torque measurement unit 5 that cooperate with each other.

[0032] The following is a detailed description of the structure of each functional unit: 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 introduce its structural composition in detail: like Figure 8-9 As shown, the feeding unit 1 includes a forward feeding platform 11 for conveying the loading jig, a conveying cross-cutting platform 12 for transporting and transferring the loading jig, and a return platform 13 for returning the empty jig; wherein, guide baffles are provided on both sides of the conveyor belts of the forward feeding platform 11 and the return platform 13 to ensure the axial positioning accuracy of the jig, and the forward feeding platform 11 is provided with a jig braking clamp 111 and a photoelectric sensor 112, and the end of its conveyor belt is connected to the conveying cross-cutting platform 12; the conveying cross-cutting platform 12 includes a platform bottom plate, a first conveying component 121 and a cross-cutting component 122 arranged above the platform bottom plate, and a second conveying component 123 and a blocking component 124 arranged below the platform bottom plate; the return platform 13 is arranged on the other side of the platform bottom plate and is arranged parallel to the forward feeding platform 11.

[0033] The platform base plate is provided with a long through-slot, which is located on the extension line of the conveyor belt of the forward platform 11. A jig baffle is provided on each side of the long through-slot to form a jig channel for the platform base plate. The blocking assembly 124 is installed below the platform base plate and comprises a blocking cylinder and a blocking tongue 124a controlled by the blocking cylinder. The blocking tongue 124a corresponds to the position of the long through-slot and, when extended upward, can block the jig channel, thereby preventing the current loading jig from continuing to move forward. The first transport assembly 121 is used to transport the loading jig that enters the platform base plate. It comprises a lifting cylinder installed on the transverse module and a transport clamp driven and controlled by the lifting cylinder. The second transport assembly 123 is used to transport the jig baffle to the cross-cutting station. It includes a lifting cylinder mounted on the transverse module and a pin 123a driven by the lifting cylinder. The pin 123a is adapted to fit into the slot at the bottom of the jig to achieve positioning and connection of the jig. The cross-cutting assembly 122 includes a cross-cutting cylinder and a cross-cutting push plate connected to its output.

[0034] The loading jig is on the forward delivery platform 11 and moves driven by the conveyor belt. When the loading jig enters the conveying cross-cutting platform 12 from the forward delivery platform 11, the first conveying component 121 moves above it, clamps the loading jig downward with its conveying claws, and drags it forward to the predetermined position. At this predetermined position, the lifting cylinder of the second conveying component 123 drives its ejector pin 123a to pass through the long through slot of the platform bottom plate and insert and position it into the slot hole at the bottom of the loading jig. The loading jig is then further conveyed to the material picking station. At this station, the products in the loading jig will be taken one by one until it is empty. At this time, the cross-cutting component 122 pushes the empty jig to the return platform 13 for return through its cross-cutting push plate.

[0035] The above process involves two blocking controls. One is on the forward platform 11. When the photoelectric sensor 112 senses that the carrier jig is passing the jig brake clamp 111, the jig brake clamp 111 is controlled to clamp the carrier jig, preventing it from moving forward to avoid interference with the jig in front. The jig in front is released after it enters the conveying and cross-cutting platform 12. The other is the blocking component 124 below the conveying and cross-cutting platform 12. Its function is to prevent the subsequent carrier jigs entering the platform floor from moving forward and to release them after the carrier jig in front enters the cross-cutting station.

[0036] The transfer unit 2 is as follows Figure 11 As shown, it includes a transfer plate 21 driven and controlled by a drive module, and a pneumatic clamp 22 and three vacuum suction cups 23 are respectively arranged on the transfer plate 21 at predetermined intervals. The pneumatic clamp 22 is used to clamp the product from the product fixture and transfer it to the visual inspection station for visual inspection, and the vacuum suction cup 23 is used to complete the subsequent suction operation of the product.

[0037] The visual detection unit 3 is as follows Figure 11 As shown, the system comprises a flip assembly 31, an industrial camera 32, and an image processing unit. The flip assembly 31 is used to rotate and position the product at multiple angles, and the industrial camera 32 is used to visually inspect the product. The flip assembly 31 includes a flip cylinder 311 and a flip gripper 312 driven and controlled by the flip cylinder. An observation platform 313, also controlled by the cylinder, is located below the flip gripper 312. The industrial camera is equipped with a ring-shaped auxiliary light source.

[0038] The electrical performance detection mechanism 5 adopts the structure described in the first embodiment, which will not be repeated here.

[0039] The defective discharge unit 6 is as follows Figure 12As shown, the system includes a defective pneumatic gripper 61, a defective discharge channel 62, and a slidably mounted defective product box 63. Multiple defective product boxes 63 are provided depending on the type of defective product. The defective pneumatic gripper 61 receives defective products from the mobile unit 2 and drops them into the defective discharge channel 62 below, where they eventually fall into the corresponding defective product box 63.
