Description

Technical Field

[0001] This utility model relates to the field of pressing machine technology, specifically to a testing mechanism for a pressing machine carrier plate fixture. Background Technology

[0002] In modern industrial production, pressing machines are a common type of equipment used to press and assemble different parts. They are widely used in many fields such as electronics, machinery, and automobiles. As an important component of pressing machines, carrier plate fixtures are used to support the workpieces to be pressed and to ensure the positional accuracy and stability of the workpieces during the pressing process. To improve their buffering, anti-slip, and insulation properties, some carrier plate fixtures are coated with a layer of silicone.

[0003] As the silicone layer on the carrier plate fixture increases with use, the silicone layer on the surface of the fixture will wear down and deform due to friction, compression, and other reasons. Currently, the detection of the wear degree of the carrier plate fixture mainly adopts two methods: manual inspection and simple physical measurement. Manual inspection relies on workers' experience and visual observation, judging the wear condition of the fixture by touching and comparing, which has extremely low detection efficiency and cannot meet the needs of large-scale production. Simple physical measurement uses tools such as calipers or micrometers to measure parameters such as the thickness change of the silicone layer of the fixture. However, this method can only obtain local and discrete measurement data, which is difficult to comprehensively reflect the overall wear condition of the fixture, and the measurement process is cumbersome. Therefore, a detection mechanism for the carrier plate fixture of the pressing machine is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the aforementioned technical problems, this invention provides a detection mechanism for a press plate fixture. This solution addresses the issue mentioned in the background section where the silicone layer on the surface of the fixture, due to friction and compression, experiences wear and deformation as usage time increases. Currently, the detection of the wear level of the fixture mainly employs two methods: manual inspection and simple physical measurement. Manual inspection relies on workers' experience and visual observation, judging the fixture's wear condition through touch and comparison, resulting in extremely low efficiency and difficulty meeting the needs of large-scale production. Simple physical measurement uses tools such as calipers and micrometers to measure parameters such as the thickness change of the silicone layer, but this method only obtains localized, discrete measurement data, making it difficult to comprehensively reflect the overall wear condition of the fixture, and the measurement process is cumbersome.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A testing mechanism for a pressing machine plate fixture includes a frame base plate. Support beams are fixedly connected to the four corners of the upper end of the frame base plate. A frame top plate is fixedly connected to the upper end of the support beams. Frame side plates are fixedly connected between the front and rear frame top plates. A frame platform is fixedly connected to the upper end of the support beams via a column. A vision inspection component is provided on the upper end of the frame platform.

A camera mounting base and a prism mounting base are fixedly connected to the left end of the second sliding seat. A visual inspection camera is fixedly connected to the inner side of the camera mounting base. A reflector is fixedly connected to the inner side of the prism mounting base. The reflector is directly opposite the lens of the visual inspection camera.

[0008] Preferably, the upper end of the mounting platform has a through slot, and the upper end of the frame platform is fixedly connected to multiple track supports on the front side of the mounting platform. The other end of the track supports is fixedly connected to a fixed linear track. The upper end of the mounting platform away from the fixed linear track has two symmetrically distributed second adjusting slide rails fixedly connected. The outer surface of the second adjusting slide rails is slidably connected to a movable linear track. The upper end of the frame platform away from the fixed linear track has a first ball screw fixedly installed. The outer surface of the nut of the first ball screw is fixedly connected to a first adjusting seat. The upper end of the mounting platform has a second ball screw fixedly installed.

By setting up a vision camera to detect the wear degree of the carrier plate fixture, and comparing the wear degree of the carrier plate fixture after different processing times based on the vision detection data, the wear degree of the carrier plate fixture can be automatically evaluated, improving the detection efficiency. At the same time, by changing the camera optical path through a reflector, it is possible to install the camera in a non-working area, which can avoid interfering with the normal operation of the pressing machine.

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] Reference Figures 1-4 As shown, a testing mechanism for a pressing machine plate fixture includes a frame base plate 1. Support beams 2 are fixedly connected to the four corners of the upper end of the frame base plate 1. A frame top plate 3 is fixedly connected to the upper end of the support beams 2. Frame side plates 10 are fixedly connected between the front frame top plate 3 and the rear frame top plate 3. A frame platform 4 is fixedly connected to the upper end of the support beams 2 through a column. A vision inspection component 24 is provided on the upper end of the frame platform 4. Two symmetrically distributed first adjusting slide rails 5 are fixedly connected to the upper end of the frame platform 4 in front of the vision inspection component 24. Two slide blocks 6 are slidably connected to the outer surface of the first adjusting slide rails 5. A mounting platform 7 is fixedly connected to the upper end of the four slide blocks 6.

[0030] The visual inspection component 24 includes a support frame 2401 fixedly connected to the upper end of the frame platform 4 via a pillar. A first electric linear guide rail 2402 is fixedly connected to the lower end of the support frame 2401. A first sliding seat 2403 is slidably connected to the first electric linear guide rail 2402. A track mounting plate 2404 is fixedly connected to the lower end of the first sliding seat 2403. A second electric linear guide rail 2405 is fixedly connected to the left end of the track mounting plate 2404. A second sliding seat 2406 is slidably connected to the second electric linear guide rail 2405. A camera mounting base 2407 and a prism mounting base 2409 are fixedly connected to the left end of the second sliding seat 2406. A visual inspection camera 2408 is fixedly connected to the inner side of the camera mounting base 2407. A reflector 2410 is fixedly connected to the inner side of the prism mounting base 2409. The reflector 2410 is directly opposite the lens of the visual inspection camera 2408.

[0031] Furthermore, the visual inspection camera 2408 is used to visually inspect the carrier fixture and feed the data back to the external control equipment. The first electric linear guide 2402 and the second electric linear guide 2405 enable the visual inspection camera 2408 to move horizontally in two dimensions. The reflector 2410 is an inclined mirror used to change the shooting direction of the visual inspection camera 2408, so that the camera can be installed on the non-pressing working area on the machine table 4, avoiding the lens from being directly aimed at the pressing working area above the carrier fixture, eliminating the interference of the inspection equipment on the normal operation of the pressing machine. With the movement of the dual electric linear guides, more comprehensive fixture image information can be obtained. By comparing the wear degree of the silicone-coated carrier fixture after different processing times, it is determined whether the carrier fixture is excessively worn. When the carrier fixture is excessively worn, the external control equipment detects abnormal data and triggers an alarm to notify the staff to replace the fixture.

[0032] Furthermore, both the first electric linear guide 2402 and the second electric linear guide 2405 adopt a drive structure combining a lead screw and a motor. The motor is installed on one side of the rail and its output end is fixedly connected to one end of the lead screw. The lead screw is rotatably installed on the inner side of the rail, and the sliding seat is threadedly connected to the outer surface of the lead screw. By driving the lead screw to rotate through the motor, the sliding seat can be moved.

[0033] Reference Figures 1-9As shown, a through groove 701 is provided through the upper end of the mounting plate 7. Multiple track supports 12 are fixedly connected to the upper end of the frame plate 4, which is located in front of the mounting plate 7. A fixed linear track 13 is fixedly connected to the other end of the track supports 12. Two symmetrically distributed second adjusting slide rails 14 are fixedly connected to the upper end of the mounting plate 7 away from the fixed linear track 13. A movable linear track 15 is slidably connected to the outer surface of the second adjusting slide rail 14. A first ball screw 16 is fixedly installed on the upper end of the frame plate 4 away from the fixed linear track 13. A first adjusting seat 17 is fixedly connected to the outer surface of the nut of the first ball screw 16. A second ball screw 18 is fixedly installed on the upper end of the mounting plate 7. A second adjusting seat 19 is fixedly connected to the outer surface of the nut of the second ball screw 18.

[0034] Furthermore, the front end of the first adjusting seat 17 is fixedly connected to the rear end of the mounting plate 7, and the front end of the second adjusting seat 19 is fixedly connected to the rear end of the movable linear track 15.

[0035] Furthermore, by driving the first adjusting seat 17 to slide along the outer surface of the first adjusting slide rail 5 via the first ball screw 16, the mounting plate 7 can be moved closer to or away from the fixed linear track 13, thereby adjusting the distance between the fixed linear track 13 and the movable linear track 15. During the adjustment process, the second ball screw 18 will simultaneously drive the second adjusting seat 19 to slide along the outer surface of the second adjusting slide rail 14, adjusting the position of the movable linear track 15, so that the movable linear track 15 and the fixed linear track 13 are always symmetrically distributed on both sides of the through groove 701. Both the first ball screw 16 and the second ball screw 18 are driven by external motors.

[0036] Furthermore, the track support 12 is L-shaped. The L-shaped structure of the track support 12 leaves a certain distance between its vertical part and the mounting platform 7, which facilitates the position adjustment of the mounting platform 7. The vertical height of the fixed linear track 13 and the movable linear track 15 are consistent.

[0037] Furthermore, platform support guide posts 8 are fixedly connected to the four corners of the upper end of the mounting platform 7, and an upper platform 9 is fixedly connected to the upper end of the platform support guide posts 8.

[0038] Furthermore, a second proximity sensor 23 is provided on one side of the first adjusting slide rail 5, a second positioning block 22 is fixedly connected to the side of the first adjusting seat 17 near the second proximity sensor 23, a first proximity sensor 21 is provided on one side of the second adjusting slide rail 14, and a first positioning block 20 is fixedly connected to the side of the second adjusting seat 19 near the first proximity sensor 21.

[0039] Furthermore, the second proximity sensor 23 is used to monitor the distance between itself and the first positioning block 20, and the second proximity sensor 23 is used to monitor the distance between itself and the second positioning block 22. Both the second proximity sensor 23 and the first proximity sensor 21 are electrically connected to the external control device. By measuring the distance in real time through the second proximity sensor 23 and the first proximity sensor 21 and feeding the data back to the external control device, the accuracy of track adjustment can be ensured.

[0040] Furthermore, a connecting seat is provided on the opposite side of both the fixed linear track 13 and the movable linear track 15 for connecting with the carrier plate fixture. The drive structure for the linear movement of the connecting seat can be any existing linear track drive structure.

[0041] Furthermore, a feed inlet 11 is provided through the right end of both side plates 10 of the frame.

[0042] Working principle: During use, the position of the mounting plate 7 is adjusted by the first ball screw 16, and the movable linear track 15 is adjusted synchronously by the second ball screw 18 to ensure that the distance between the two tracks matches the width of the fixture. Then, the carrier plate fixture covered with silicone is fixed between the fixed linear track 13 and the movable linear track 15 through the connecting seat. During the processing, the vision inspection camera 2408 can move along two axial directions under the drive of the first electric linear guide 2402 and the second electric linear guide 2405 to scan the surface of the fixture, clearly capture the wear details of the silicone layer at the edge of the fixture, and feed the data back to the external control equipment. The control equipment compares the current image with the initial reference image and calculates the change in the thickness of the silicone layer. When the thickness of a certain area decreases by more than 10%, it is determined to be excessive wear, and an alarm is triggered to notify the staff to replace the fixture.
