Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fixing devices for optical inspection machines, specifically a fixing fixture for a CCD optical inspection machine. Background Technology
[0002] A CCD optical inspection machine is a precision inspection device based on CCD (Charge-Coupled Device) technology. It uses a CCD camera to photograph the target object, converting optical signals into electrical signals to obtain high-definition images of the object's surface. It is used to detect appearance defects, dimensional accuracy, and pin deformation of electronic components, such as integrated circuit chips, resistors, capacitors, and inductors. It can also inspect printed circuit boards (PCBs), including detecting problems such as short circuits, open circuits, poor soldering, and missing components.
[0003] The main components of the fixture for a CCD optical inspection machine include a base, positioning blocks, clamping devices, fine-tuning mechanisms, and sensors. The base is used for stable fixture mounting; the positioning blocks accurately position the workpiece; the clamping devices ensure the workpiece remains stationary during inspection; the fine-tuning mechanisms allow for minor adjustments to the workpiece position, ensuring inspection accuracy; and the sensors detect whether the workpiece is correctly positioned and clamped. In use, the fixture is first fixed to the inspection machine's worktable, the workpiece is placed using the positioning blocks, secured by the clamping devices, then the workpiece is adjusted to the appropriate position using the fine-tuning mechanisms, and finally, the sensors confirm the workpiece's positioning status to ensure smooth inspection.
[0004] During use, the operator first places the object to be processed on the clamping plate of the fixing device. The clamping structure of the clamping plate initially fixes the material. Then, the fixing device holding the object is pushed or moved to bring it into the detection area of the CCD optical inspection machine. During the movement, if the material has an irregular shape, its center of gravity distribution is often uneven. In addition, the vibration that may be generated by the fixing device sliding on the guide rail and moving the worktable can cause the material to bounce on the clamping plate. This bounce will cause the material to deviate from the initial positioning position, and the relative angle between the surface features and the CCD camera will change, which will lead to blurring and distortion of the acquired image. Utility Model Content
[0005] The purpose of this utility model is to provide a fixing fixture for a CCD optical inspection machine, so as to solve the problem that when using it, the operator first places the object to be processed on the clamping plate of the fixing device, and the material is initially fixed by the clamping structure of the clamping plate. Then, the fixing device holding the object is pushed or moved to make it enter the inspection area of the CCD optical inspection machine. During the movement, if the shape of the material is irregular, its center of gravity distribution is often uneven. In addition, the vibration that may be generated by the fixing device during the sliding of the guide rail and the translation of the worktable will cause the material to bounce on the clamping plate. This bounce will cause the material to deviate from the initial positioning position, and the relative angle between the surface features and the CCD camera will change, which will lead to blurring and distortion of the acquired image.

[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This invention supports the device body via a support rod mounted on the base plate. Two guide plates and a guide rail on the base plate ensure the bearing platform does not shift position during movement, guaranteeing good stability when the material is clamped and moved. When the material to be tested is placed on the device's sliding plate, the pressure generated by the material presses down on the sliding plate. This pressure, via a connecting rod, moves the sliding rod downwards and presses down the airbag. The gas generated by the airbag controls the extension and retraction of the clamping plate through an air supply pipe, ensuring the material surfaces of the clamping plates are in contact. Furthermore, the hanging rod and hook engage to secure the device, preventing positional shift during movement and ensuring the accuracy of the test data. Attached Figure Description

[0028] The fixing unit includes a support platform 2 slidably mounted on a base plate 1, a top plate 21 fixedly mounted on the support platform 2, a carrying plate 3 fixedly mounted on the top plate 21, a housing 31 fixedly mounted on the carrying plate 3, a sliding plate 34 slidably mounted on the housing 31, a positioning plate 32 fixedly mounted on the sliding plate 34, and a clamping plate 33 slidably mounted on the positioning plate 32. The fixing unit is used to position and fix the material to be tested.
[0029] Referring to the figure, multiple parallel support rods 11 are fixedly installed on the bottom of the base plate 1, and each support rod 11 is evenly distributed at each corner of the base plate 1. The support rods 11 installed on the base plate 1 provide support for the main body of the device. At the same time, the even distribution of each support rod 11 at the corner of the base plate 1 ensures that each support rod 11 can be subjected to uniform force, avoiding damage to the support rods 11 due to uneven force, and ensuring the safety and stability of the device.
[0030] Reference Figures 1-3 A guide rail 121 is fixedly installed on the guide plate 12, and the top plate 21 is attached to the guide rail 121. The guide rail 121 on the guide plate 12 ensures that the top plate 21 will not shift during movement, thereby ensuring the stability of the device during overall operation.
[0031] Reference Figures 2-4 Multiple parallel brackets 341 are fixedly installed on the bottom of the slide plate 34, and two adjacent brackets 341 are combined to form a limiting component. A connecting rod 342 is rotatably installed on the limiting component. A guide groove is provided on the outer shell 31, and a sliding rod 35 is slidably installed on the guide groove. The sliding rod 35 is rotatably connected to the connecting rod 342. Another set of limiting components is provided on the carrying plate 3. A spring 343 is fixedly installed between the slide plate 34 and the carrying plate 3. Through the slide plate 34 installed on the outer shell 31, when the staff places the material on the slide plate 34 of the device, the clamping plate 33 on the slide plate 34 can clamp and fix the material.
[0032] Reference Figures 2-4 A hook 36 is fixedly installed on the side wall of the outer shell 31, and a hanging rod 38 is slidably installed on the bottom end of the slide plate 34. The hanging rod 38 and the hook 36 are engaged with each other. The hook 36 installed on the outer shell 31 can limit and fix the hanging rod 38, thereby fixing the slide plate 34.
[0033] Reference Figures 2-4 An airbag 7 is fixedly installed on the carrying plate 3. A pressure rod is slidably installed on the airbag 7. The pressure rod is slidably connected to the sliding rod 35. An air supply pipe is fixedly installed on the airbag 7. The other end of the air supply pipe is fixedly connected to the positioning plate 32. When the sliding plate 34 moves, it can press down on the airbag 7. At this time, the gas generated by the airbag 7 can be transported to the positioning plate 32 through the air supply pipe, thereby realizing the control of the extension and retraction of the clamping plate 33 to clamp the material.
[0034] Reference Figures 3-4A housing 37 is fixedly installed on the bottom of the slide plate 34. A telescopic plate is slidably installed inside the housing 37. The other end of the telescopic plate is fixedly connected to the hanging rod 38. A second spring 39 is fixedly installed between the telescopic plate and the housing 37. Through the housing 37 installed on the slide plate 34, the elastic force generated by the second spring 39 in the natural state is guaranteed to ensure that the hanging rod 38 will not detach from the hook 36.
[0035] Reference Figure 4 Anti-slip sleeves 381 are fixedly installed on both ends of the hanging rod 38. The diameter of the anti-slip sleeves 381 is not less than the diameter of the hook 36. The anti-slip sleeves 381 installed on the hanging rod 38 prevent the hanging rod 38 from slipping off during use.
[0036] The specific solution is as follows: When in use, the staff first places the device in the predetermined position for fixation. The support rod 11 set on the base plate 1 provides support for the device body. The two guide plates 12 and the guide rail 121 on the base plate 1 can ensure that the bearing platform 2 will not shift during movement, ensuring good stability when the material moves after being clamped. When the material to be tested is placed on the slide plate 34 of the device, the pressure generated by the material can press down the slide plate 34. The pressed slide plate 34 can drive the slide rod 35 to move down through the connecting rod 342. During the movement of the slide plate 34, it can press down the air bag 7. At this time, the gas generated by the air bag 7 can be transported to the positioning plate 32 through the air supply pipe, thereby realizing the control of the extension and retraction of the clamping plate 33 to clamp the material. The sleeve 37 set on the slide plate 34 ensures that the elastic force generated by the spring 39 in the natural state can ensure that the hanging rod 38 will not disengage from the hook 36, ensuring the stability of the device clamping.
