Description

Technical Field

[0001] This invention relates to the field of elasticity testing device technology, and more specifically to a device for testing the elasticity of hanger teeth. Background Technology

[0002] Hangers are core auxiliary tooling in industrial production processes such as electroplating, spraying, and workpiece suspension. The hanging teeth on the hanger are mainly used to hold and suspend the workpiece, and their elasticity directly determines the stability and reliability of the workpiece suspension. If the elasticity of the hanging teeth is too high, it can easily lead to workpiece deformation during clamping and disassembly, making it difficult to assemble and disassemble. If the elasticity of the hanging teeth is too low, it can cause the workpiece to loosen during suspension and fall off during processing, seriously affecting product processing quality and even causing production safety accidents. Therefore, it is necessary to use an elasticity testing device to test the elasticity of the hanging teeth of the hanger.

[0003] However, the current traditional method of testing the elasticity of hanger teeth is mostly manual sampling, relying on human touch to judge whether the elasticity of the hanger teeth is qualified. The testing accuracy is low and it cannot achieve standardized and quantitative testing. At the same time, there is a lack of supporting shaping, correction, re-inspection and defective product buffering mechanisms. The testing, correction and sorting processes are scattered, with low automation and poor production efficiency, making it difficult to meet the needs of batch and high-precision hanger testing and production. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides a hanger tooth elasticity detection device. By integrating a transfer flow line, barcode scanning and identification, elasticity detection, shaping and correction, secondary re-inspection, transfer and circulation, and defective product buffering mechanism on the top of the inspection machine, it realizes integrated automated operation of hangers from feeding, inspection, correction, re-inspection to good product output and NG product buffering, without manual intervention, greatly improving production efficiency and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hanger tooth elasticity detection device, comprising a detection machine base, wherein the top of the detection machine base is provided with a first hanger transfer streamline, a barcode scanner, a hanger detection module, a hanger shaping and correction module, a hanger re-inspection module, a hanger lifting and transfer module, a second hanger transfer streamline, and an NG hanger buffer module, wherein a main flow line is provided between the first hanger transfer streamline and the second hanger transfer streamline, wherein both the hanger detection module and the hanger re-inspection module include a first straight line module, wherein the bottom of the first straight line module is connected to the top of the detection machine base through two first columns, and the hanger tooth elasticity detection module is fixedly provided at the bottom of the slide of the first straight line module.

[0006] In a preferred embodiment, the toothed elasticity detection module includes a detection frame, an electric push rod is fixedly installed inside the detection frame, a lifting plate is fixedly installed at the bottom end of the piston rod of the electric push rod, and a plurality of pneumatic grippers arranged in a linear array are fixedly installed at the bottom of the lifting plate. A first pressure sensor is fixedly installed on the two gripper plates of each pneumatic gripper, and a second pressure sensor is installed between the two first pressure sensors. The multiple sensors cooperate to achieve multi-point, high-precision elasticity detection.

[0007] In a preferred embodiment, the hanging fixture shaping and correction module includes a second straight module, the bottom of the second straight module is connected to the top of the testing machine through two second columns, and an elastic correction component is fixedly provided at the bottom of the slide of the second straight module.

[0008] In a preferred embodiment, the elasticity correction component includes a fixed plate, and a plurality of equally spaced lead screw modules are fixedly disposed on the bottom of the fixed plate. Each lead screw module has an L-shaped shaping block fixedly disposed on the bottom of its slider. A CCD industrial camera is fixedly disposed on one side of the fixed plate. The CCD industrial camera is used to locate the position of the hanging teeth. The lead screw modules drive the L-shaped shaping blocks to perform lateral or radial correction on the hanging teeth with unqualified elasticity, so as to restore them to the standard elasticity range.

[0009] In a preferred embodiment, a feeding machine and a discharging machine are respectively provided on both sides of the rear end of the testing machine. The front end of the feeding machine and the front end of the discharging machine are each provided with two lifting modules distributed in front and behind, which are used to realize the automatic feeding and receiving of the hanger.

[0010] In a preferred embodiment, the NG hanger buffer module includes a base, and a layered check frame is provided on the top of the base. Multiple check components are fixedly provided on both inner walls of the layered check frame at equal intervals, and the check components on both sides correspond one-to-one. The check component includes a proximity switch, and a reflective photoelectric sensor is fixedly provided on the side of the layered check frame near the mains line.

[0011] In a preferred embodiment, synchronous pulleys are fixedly provided on the inner walls of both the front and rear sides of the layered check frame, and stepper motors are installed on the outer walls of both the front and rear sides of the base to drive the synchronous pulleys to rotate. A lifting electric cylinder module is fixedly provided inside the base to drive the layered check frame to lift.

[0012] In a preferred embodiment, the layered check frame is fixedly provided with a hanging edge on the side away from the reflective photoelectric source, and the base is fixedly provided with a blocking cylinder on the side away from the main flow line.

[0013] The aforementioned NG hanger buffer module can buffer hangers that fail re-inspection in layers. The stepper motor and synchronous pulley work together to achieve horizontal entry and exit of the hangers, the lifting electric cylinder realizes layered lifting and lowering, and the check valve component prevents the hangers from slipping out, thus achieving space-saving automatic buffering.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention integrates a transfer flow line, barcode recognition, elasticity detection, shaping and correction, secondary inspection, transfer and circulation, and defective product buffering mechanism on the top of the inspection machine. This enables the fixture to achieve integrated automated operation from feeding, inspection, correction, and re-inspection to good product output and NG product buffering without manual intervention, thus greatly improving production efficiency. 2. By setting up multiple pressure sensors in conjunction with pneumatic grippers to simulate the workpiece suspension state, the clamping force of the gripping teeth is accurately detected, eliminating the error problem of traditional manual detection. With the addition of a front-mounted barcode scanner, data traceability of a single fixture can be achieved, and the detection data is accurate and can be recorded.

[0015] 3. A dedicated fixture shaping and correction module is set up. The module uses a CCD industrial camera for visual positioning and a lead screw module to drive the L-shaped shaping block to precisely adjust the deformation of the hanging teeth. This allows for precise correction of fixtures with unacceptable elasticity. After correction, the fixtures can be re-inspected by the re-inspection module, which significantly reduces the cost of scrapping fixtures. 4. By setting up an NG fixture buffer module and adopting a layered buffer structure, combined with a check valve component, photoelectric sensor and lifting electric cylinder module, defective fixtures can be buffered in a layered and orderly manner, avoiding the accumulation and chaos of defective products, and adapting to the needs of batch continuous operation on the production line.

[0019] Refer to the instruction manual appendix Figures 1-9 This invention provides a device for detecting the elasticity of hanger teeth, including a testing machine 1.

The cooperation of multiple sensors can collect tooth elasticity data from all directions, accurately determine whether the tooth elasticity is within the qualified range, and realize quantitative detection.

[0021] The fixture shaping and correction module 5 includes a second straight module 51. The bottom of the second straight module 51 is connected to the top of the testing machine 1 through two second columns 52. An elastic correction component 53 is fixedly provided at the bottom of the slide of the second straight module 51.

[0022] like Figure 7 and Figure 8 As shown, the elastic correction component 53 includes a fixed plate 531. Multiple equally spaced lead screw modules 532 are fixedly arranged at the bottom of the fixed plate 531. An L-shaped shaping block 533 is fixedly arranged at the bottom of the slider of each lead screw module 532. A CCD industrial camera 534 is fixedly arranged on one side of the fixed plate 531, which can collect images of the tooth shape and identify the deformation position and deviation of the tooth through visual positioning, providing data basis for the correction stroke of the lead screw module 532 and realizing visual precision correction.

[0023] The mounting bracket lifting and transfer module 7 may include a rotating platform. A Y-axis linear module is fixedly mounted on the top of the rotating platform. A blocking and positioning platform is fixedly mounted on the top of the slider of the Y-axis linear module. This platform can limit and block the mounting bracket, accurately fix the position of the mounting bracket, prevent the mounting bracket from shifting during operation, and ensure the accuracy of detection and correction. Since this is existing technology, it will not be described in detail.

[0024] like Figure 2 As shown, the rear sides of the testing machine 1 are respectively provided with a feeding machine 14 and a discharging machine 15. The front end of the feeding machine 14 and the front end of the discharging machine 15 are each provided with two lifting modules 16 distributed in front and behind, which can be adapted to the docking of production lines of different heights. At the same time, the automatic docking, feeding and unloading of the fixtures are completed through the lifting action, thereby improving the automation adaptability of the equipment.

[0025] like Figure 1 , Figure 2 and Figure 9As shown, the NG hanger buffer module 9 includes a base 91, and a layered check frame 92 is provided on the top of the base 91. Multiple check components 93 are fixedly provided on the inner walls of both sides of the layered check frame 92, and the check components 93 on both sides correspond one to one. Each check component 93 includes a proximity switch 94. A reflective photoelectric sensor 95 is fixedly provided on the side of the layered check frame 92 near the main line 10, which is used to sense the feeding action of the defective hanger and trigger the operation of the buffer mechanism.

[0026] like Figure 9 As shown, synchronous pulleys 96 are fixedly provided on the inner walls of the front and rear sides of the layered check frame 92, and stepper motors 97 are installed on the outer walls of the front and rear sides of the base 91 to drive the synchronous pulleys 96 to rotate.

[0028] In actual use, the device works as follows: First, the operator loads the fixture onto the loading machine 14 using the existing fixture trolley. The lifting module 16 then transports the fixtures from the trolley to the first fixture transfer line 2. The first fixture transfer line 2 then transports the fixtures to the main line 10, where the barcode scanner 3 scans and records the fixture number. The fixtures then move to the area below the fixture detection module 4. The electric push rod 132 in the tooth elasticity detection module 13 drives the lifting plate 133 to move downwards. The lifting plate 133 then moves the pneumatic gripper 134, the first pressure sensor 135, and the second pressure sensor 136 downwards together, completing the tooth elasticity detection. The system tests whether the elasticity is qualified. After testing, the hanger is transferred to the hanger shaping and correction module 5. After visual positioning by the CCD industrial camera 534, the L-shaped shaping block 533 accurately shapes and corrects the abnormal hanger teeth. After correction, the hanger is transferred to the hanger re-inspection module 6 for a second elasticity test. The hanger that passes the re-inspection is transferred to the second hanger transfer line 8 by the lifting and transfer module, and finally discharged by the unloading machine 15. The NG hanger that still fails the re-inspection is transferred to the NG hanger buffer module 9 by the lifting and transfer module. The layered check frame 92 completes the layered orderly buffering and completes the fully automated detection and correction operation.

[0029] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
