The nut is fixedly connected to the spectrometer 2. The spectrometer 2 achieves precise movement in the X, Y, and Z directions through the first driving assembly 21, the second driving assembly 22, and the third driving assembly 23.

The first connecting plate 41 and the second connecting plate 42 are connected by the cooperation of elongated holes and connecting holes. That is, the first connecting plate 41 has a plurality of first connecting holes 411 arranged along the Z-axis, and the second connecting plate 42 has a first elongated hole 421 arranged along the Z-axis and cooperating with the first connecting holes 411. The first connecting plate 41 and the second connecting plate 42 are connected by bolts. This allows for a significant adjustment of the position of the workpiece plate 31 in the Z-axis direction.

[0030] The fourth drive assembly 3 includes a second drive motor 32 fixedly connected to the second connecting plate 42, a drive pulley driven by the second drive motor 32, a driven pulley connected to the drive pulley via a synchronous belt, a screw threaded to the driven pulley, a slider 34 fixedly connected to the screw, and a slide block 33 slidably connected to the slider 34. The driven pulley is rotatably connected to the second connecting plate 42 via a bearing. The slide block 33 is fixedly connected to the second connecting plate 42 and has a slide rail arranged along the Z-axis. The slider 34 is fixedly connected to the workpiece plate 31. The second drive motor 32 drives the drive pulley to rotate, and the drive pulley drives the driven pulley to rotate via a synchronous belt, thereby driving the slider 34 on the screw to move the workpiece plate 31 up and down along the Z-axis. The workpiece plate 31 can be adjusted significantly by the stroke compensation assembly 4 and finely by the fourth drive assembly 3, making operation convenient and highly accurate.

[0031] like Figure 5 , 6As shown in Figure 7, the stroke compensation component 4 and the fourth drive component 3 are located on one side of the detection station along the X-axis, and the pressure plate 51 and the buffer component 5 are located on the other side of the detection station along the X-axis. The buffer component 5 includes a guide post 52, a bushing 53 sleeved on and slidably connected to the guide post 52, and a first fixing block 55 and a second fixing block 56 respectively located on the upper and lower parts of the bushing 53. The first fixing block 55 and the second fixing block 56 are both fixed to the guide post 52 by bolts. The bushing 53 is located between the first fixing block 55 and the second fixing block 56. Between blocks 56, the bottom of the guide post 52 is fixed to the base 12, and the top of the guide post 52 passes through the second fixing block 56, the bushing 53, and the first fixing block 55 in sequence. A first spring 551 is provided between the first fixing block 55 and the bushing 53. The first spring 551 is sleeved on the guide post 52 and its two ends are respectively connected to the first fixing block 55 and the bushing 53. A second spring 561 is provided between the second fixing block 56 and the bushing 53. The second spring 561 is sleeved on the guide post 52 and its two ends are respectively connected to the second fixing block 56 and the bushing 53. The bushing 53 is fixedly connected to the pressure plate 51 through a connector 54. The pressure plate 51 is arranged above the workpiece plate 31 along the Z-axis direction. To ensure uniform force distribution on the buffer assembly 5, two guide posts 52 are provided on the base 12. These two guide posts 52 are fixed to both sides of the base 12 along the Y-axis. Each guide post 52 corresponds to a pressure plate 51, which is also positioned along the Y-axis on both sides of the workpiece plate 31, ensuring effective fixation of the workpiece 8. The front end of the pressure plate 51 extends towards the workpiece plate 31, and the rear end of the pressure plate 51 has a fifth elongated hole. The connecting member 54 has a third connecting hole that mates with the fifth elongated hole. The pressure plate 51 and the connecting member 54 are connected by bolts, allowing for fine-tuning of the pressure plate 51 in the X-axis direction. When the workpiece 8 is lifted upwards by the workpiece plate 31 and contacts the pressure plate 51, the force on the pressure plate 51 is transmitted through the bushing 53 to the first spring 551 and the second spring 561, providing flexible buffering and reducing rigid contact between the workpiece 8 and the pressure plate 51, thus preventing damage to both due to rigid contact.

[0032] like Figure 8 and Figure 9As shown, the workpiece plate 31 is provided with a through hole 311 for calibration. The calibration assembly 6 includes a calibration plate 61 disposed at the through hole 311 of the workpiece plate 31, a mounting plate 63 fixed on the base 12, a light source 62, a third connecting plate 64 disposed on the mounting plate 63, and a camera 65 fixed on the third connecting plate 64. The mounting plate 63 is provided with a second elongated hole disposed along the Z-axis direction. The third connecting plate 64 is provided with a second connecting hole that mates with the second elongated hole. The third connecting plate 64 is connected to the mounting plate 63 by bolts, thereby allowing manual adjustment of the position of the camera 65 in the Z-axis direction. The light source 62 is disposed between the workpiece plate 31 and the camera 65. Before inspecting workpiece 8, turn on the light source 62, adjust the position of workpiece plate 31 in the Z-axis direction through the stroke compensation component 4 and the fourth drive component 3, manually adjust the position of camera 65 in the Z-axis direction through the cooperation of the second elongated hole and the second connecting hole, and adjust the position of spectrometer 2 in the X, Y and Z directions through the first drive component 21, the second drive component 22 and the third drive component 23 for calibration. After calibration, remove calibration plate 61 from workpiece plate 31 and proceed with the film thickness inspection process of workpiece 8.

[0033] like Figure 1 , 10 As shown in Figure 11, the guide assembly 7 is arranged on both sides of the inspection station along the Y-axis. The guide assembly 7 includes two guide plates 71 arranged along the X-axis, a first roller 72 and a second roller 73 disposed between the two guide plates 71. The lower part of one side of the guide plate 71 is provided with a third elongated hole 711 for installing the first roller 72, and the upper part of the other side of the guide plate 71 is provided with a fourth elongated hole 712 for installing the second roller 73. The third elongated hole 711 and the fourth elongated hole 712 are both arranged along the Z-axis, and they are also arranged vertically along the Z-axis. That is, there is a gap between the first roller 72 and the second roller 73 in the Z-axis direction. The gap between them forms a guide channel for the workpiece 8 to pass through. The frame 1 has openings 13 on both sides for workpieces 8 to pass through. The openings 13 correspond to the guide channels, and the two openings 13 correspond one-to-one with the guide components 7 on both sides. The workpiece 8 passes through one of the openings 13 and the guide channel corresponding to that opening 13 in sequence along the Y-axis direction to enter the inspection station for inspection. After inspection, it passes through the other guide channel and the other opening 13. The frame 1 is also provided with a third roller 14 at the opening 13 for limiting and guiding the workpiece 8. The third roller 14 is located on one side of the opening 13 along the X-axis direction.

[0034] This invention achieves automatic adjustment of the spectrometer 2 in the X, Y, and Z directions through the first, second, and third drive components, enabling rapid and accurate alignment of the test points at different locations. It is suitable for online testing of various terminal connectors, with a high degree of overall automation, effectively improving testing efficiency. The fourth drive component 3 drives the workpiece plate 31 to automatically rise and fall along the Z-axis, realizing automatic clamping and loosening of the workpiece 8. With the stroke compensation component 4, it can compensate for the processing and assembly errors of the parts, flexibly adjust the reference stroke of the workpiece plate 31, and facilitate equipment debugging. By setting a buffer component 5, it can provide flexible buffering when the workpiece plate 31 is lifted and clamped, reducing the rigid contact between the pressure plate 51 and the workpiece 8, avoiding damage to the precision terminal workpiece 8 and extending the service life of the equipment. The calibration component 6 achieves calibration, significantly improving the accuracy of film thickness detection. The guide component 7 guides the workpiece 8 to enter the testing station smoothly and accurately, ensuring the stability of online testing.
