Description

Technical Field

[0001] This application relates to the field of workpiece appearance inspection technology, and in particular to a cleaning device for workpiece appearance inspection equipment. Background Technology

[0002] After mass production is completed, the appearance of the workpieces needs to be inspected in order to ensure that their appearance meets the design and usage requirements. Workpieces with cracks or defects (unqualified workpieces) are separated from qualified workpieces to ensure that unqualified workpieces cannot flow into the next production process or be put into use.

[0003] For example, if a ceramic workpiece needs to be produced, after the workpiece is produced, an appearance inspection device is used to inspect each workpiece produced in batches. During use, the workpiece is transported to the appearance inspection device by a feeding device, and the working status of the appearance inspection device is controlled by a controller to achieve the inspection of the workpiece.

[0004] However, when inspecting workpieces using a visual inspection device, due to material properties or vibrations, debris or foreign objects (hereinafter referred to as particulate matter) on the workpiece surface will fall off along the workpiece surface, causing the particulate matter to accumulate on the visual inspection device. As the particulate matter continues to accumulate on the visual inspection device, it will affect the normal operation of the visual inspection device and is not conducive to maintaining the inspection accuracy of the visual inspection device, thus leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device for workpiece appearance inspection equipment in order to reduce the amount of particulate matter accumulating on the appearance inspection device.

[0006] To achieve the above objectives, the cleaning device for workpiece appearance inspection equipment provided in this application adopts the following technical solution:

[0007] A cleaning device for a workpiece appearance inspection equipment includes a frame and an appearance inspection device mounted on the frame. A support plate is rotatably supported on the frame for carrying workpieces. An adjustment mechanism is provided on the frame located on one side of the support plate. The adjustment mechanism includes a longitudinal adjustment component, and a cleaning mechanism is movably connected to the longitudinal adjustment component. The cleaning mechanism includes a cleaning component and a protective cover. The cleaning component is rotatably supported within the protective cover. A negative pressure pipeline is connected to the protective cover. The protective cover is located above the support plate, and a rotational gap is provided between the surface of the protective cover facing the support plate and the surface of the support plate facing the protective cover.

[0008] Preferably, the longitudinal adjustment assembly includes a longitudinal adjustment frame, a longitudinal slider, and a first handle bolt. The longitudinal slider slides in cooperation with the longitudinal adjustment frame. The first handle bolt is threaded through the longitudinal slider and abuts against the side wall of the longitudinal adjustment frame. A support plate is provided on the longitudinal slider, and a mounting plate is movably connected to the support plate. The cleaning component is rotatably supported on the mounting plate.

[0009] Preferably, the support plate is provided with a movable shaft, and the mounting plate is provided with a rotating hole, and the movable shaft is rotatably engaged with the rotating hole.

[0010] Preferably, a plurality of adjustment holes are provided in a circular array along the support plate with the axis of the movable shaft as the center, and a plurality of locking holes are provided on the mounting plate with the center of the rotating hole as the base point to the edge of the mounting plate. The distance between the center point of the adjustment hole and the axis of the movable shaft is equal to the distance between the center point of the locking hole and the axis of the movable shaft.

[0011] Preferably, the cleaning mechanism further includes a drive motor, a coupling, and a main shaft. The main shaft is rotatably supported on the mounting plate and is coaxially fixed with the cleaning component. The drive motor is mounted on the mounting plate. The drive shaft of the coupling is coaxially fixed with the output shaft of the drive motor, and the driven shaft of the coupling is coaxially fixed with the main shaft. The drive shaft and the driven shaft of the coupling are locked together.

[0012] Preferably, a limiting groove is formed on the circumferential direction of the bearing plate, so that when the bearing plate rotates along the frame, the workpiece is located in the limiting groove.

[0013] Preferably, the rotation gap is set between 0.25mm and 1.00mm.

[0014] Compared with the prior art, the present invention provides a cleaning device for workpiece appearance inspection equipment, which has the following beneficial effects:

[0015] 1. The workpiece is transported via a carrier plate. The cleaning mechanism is installed on the longitudinal adjustment assembly. As the cleaning component rotates and is carried inside the protective cover, the surface of the carrier plate is cleaned by the cleaning component when the carrier plate rotates along the frame. This causes the particles on the carrier plate to move randomly. The protective cover restricts the particles to move only inside the protective cover. Because the protective cover is connected to a negative pressure pipeline, the inside of the protective cover is in a negative pressure state. The negative pressure is used to extract the particles inside the protective cover, thereby achieving the purpose of cleaning the particles on the surface of the carrier plate. This plays a positive guiding role in reducing the amount of particles accumulating on the appearance inspection device.

[0016] 2. Because the support plate is equipped with a movable shaft and the mounting plate is provided with a rotating hole, the movable shaft and the rotating hole are rotatably engaged, so that the mounting plate can rotate along the movable shaft along the mounting position of the support plate. This achieves the purpose of adjusting the positional relationship between the protective cover and the bearing plate, and facilitates the adjustment of the cleaning path of the cleaning parts to clean the bearing plate.

[0017] 3. The drive motor and the main shaft are connected by a coupling, and the cleaning component is fixed coaxially with the main shaft, realizing the transmission of power from the output shaft of the drive motor to drive the cleaning component to rotate along the mounting plate. It also facilitates the disassembly of the cleaning component along the mounting plate, so as to quickly achieve the purpose of cleaning or replacing the cleaning component. The operation is simple.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a cleaning device for a workpiece appearance inspection equipment. (Refer to...) Figure 1 and Figure 2A cleaning device for workpiece appearance inspection equipment includes a frame 1 and an appearance inspection device 2 mounted on the frame 1. A support plate 3 is rotatably supported on the frame 1. The support plate 3 is used to support workpieces. An adjustment mechanism 4 is provided on the frame 1 located on one side of the support plate 3. The adjustment mechanism 4 includes a longitudinal adjustment component 41. A cleaning mechanism 5 is movably connected to the longitudinal adjustment component 41. The cleaning mechanism 5 includes a cleaning component and a protective cover 52. The cleaning component is rotatably supported inside the protective cover 52. A negative pressure pipeline 6 is connected to the protective cover 52. The protective cover 52 is located above the support plate 3.

[0025] First, it should be noted that a disk mounting position is reserved on the frame 1. A servo motor (not shown in the figure) is installed on the frame 1 at the disk mounting position. The output shaft of the servo motor moves through the frame 1 and is fixed coaxially with the support disk 3. By utilizing the characteristics of the servo motor, such as high-precision closed-loop control capability, rapid response, large output torque and stable operation, the purpose of driving the support disk 3 to rotate stably along the disk mounting position on the frame 1 is achieved.

[0026] Meanwhile, a limiting groove 31 is provided on the circumferential side of the bearing plate 3. When the bearing plate 3 rotates along the frame 1, the workpiece is located in the limiting groove 31. The cross-sectional shape of the limiting groove 31 is V-shaped. The limiting groove 31 is formed by the surface of the bearing plate 3 facing the cleaning part along the thickness direction. The limiting groove 31 supports the workpiece, improves the stability of the workpiece and the bearing plate 3 when the bearing plate 3 carries the workpiece and rotates along the frame 1, and avoids the workpiece from being displaced along the bearing plate 3 when the bearing plate 3 rotates along the frame 1.

[0027] Meanwhile, the appearance inspection device 2 consists of a camera recognition module, which collects images of various parts of the workpiece surface and sends them to the controller. The controller processes the images to determine whether the workpiece is qualified. It is a conventional workpiece appearance inspection component, and its specific composition and working principle will not be described in detail here.

[0028] Specifically, refer to Figure 3 The adjustment mechanism 4 also includes a lateral adjustment component 42, which includes a lateral sliding seat 421, a lateral slider 422, and a second handle bolt 423. The lateral sliding seat 421 is mounted on the frame 1 on one side of the bearing plate 3. The lateral slider 422 slides and engages with the lateral sliding seat 421. Meanwhile, the second handle bolt 423 is threaded through the lateral slider 422 and abuts against the lateral sliding seat 421.

[0029] Furthermore, the longitudinal adjustment assembly 41 includes a longitudinal adjustment frame 411, a longitudinal slider 412, and a first handle bolt 413. The longitudinal slider 412 slides with the longitudinal adjustment frame 411. The longitudinal adjustment frame 411 is mounted on the transverse slider 422, and the spatial position of the longitudinal adjustment frame 411 and the transverse slider 422 are perpendicular to each other. The first handle bolt 413 is threaded through the longitudinal slider 412 and abuts against the side wall of the longitudinal adjustment frame 411. A support plate 8 is provided on the longitudinal slider 412. The support plate 8 and the longitudinal slider 412 can be fixedly connected by bolts. A mounting plate 9 is movably connected to the support plate 8, and the cleaning component is rotated and supported on the mounting plate 9.

[0030] Therefore, when it is necessary to adjust the distance between the longitudinal adjustment frame 411 and the bearing plate 3, the second handle bolt 423 can be loosened along the transverse slider 422, thereby enabling the transverse slider 422 to support the longitudinal adjustment frame 411 to slide along the transverse sliding seat 421, thereby achieving the purpose of adjusting the distance between the longitudinal adjustment frame 411 and the bearing plate 3. After the adjustment is completed, the second handle bolt 423 only needs to be tightened again.

[0031] Correspondingly, if it is necessary to adjust the distance between the cleaning component and the carrier plate 3, the first handle bolt 413 can be loosened along the longitudinal slider 412, so that the longitudinal slider 412 can support the support plate 8 to slide along the longitudinal adjustment frame 411, so as to achieve the purpose of adjusting the distance between the cleaning component and the carrier plate 3.

[0032] Reference Figure 3 and Figure 4 A movable shaft 81 is provided on the support plate 8, and a rotating hole 91 is provided on the mounting plate 9. The movable shaft 81 and the rotating hole 91 are rotatably engaged.

[0033] Specifically, the support plate 8 has a threaded hole extending through it along its thickness direction. The movable shaft 81 is threaded into the threaded hole, allowing the movable shaft 81 to be stably mounted on the support plate 8. Simultaneously, a rotating hole 91 is formed by the mounting plate 9 extending through it along its thickness direction. The diameter of the rotating hole 91 and the diameter of the movable shaft 81 are in a transition fit, allowing the mounting plate 9 to rotate smoothly along the shaft through the rotating hole 91. This achieves the purpose of adjusting the relative position between the cleaning component and the support plate 3.

[0034] Furthermore, with the axis of the movable shaft 81 as the center, a number of adjustment holes 82 are provided in a circular array along the support plate 8. With the center of the rotating hole 91 as the reference, a number of locking holes 92 are provided on the mounting plate 9 to the edge of the mounting plate 9. The distance between the center point of the adjustment hole 82 and the axis of the movable shaft 81 is equal to the distance between the center point of the locking hole 92 and the axis of the movable shaft 81.

[0035] In this context, "several" is used to indicate quantity, rather than to limit the number of adjustment holes 82 and locking holes 92.

[0036] Specifically, there are twelve adjustment holes 82, which are evenly distributed on the support plate 8 with the axis of the movable shaft 81 as the reference. Correspondingly, there are four locking holes 92, which are arranged in a rectangular array about the center of the rotating hole 91 on the mounting plate 9. The diameter of the locking holes 92 is larger than that of the adjustment holes 82, and each adjustment hole 82 is threaded. The mounting plate 9 is fixedly connected to the support plate 8 by bolts and threaded fittings through the locking holes 92.

[0037] Therefore, when it is necessary to adjust the angle between the mounting plate 9 and the support plate 8, the bolts can be loosened along the locking hole 92 and the adjusting hole 82. Then, the mounting plate 9 is driven to rotate along the movable shaft 81 through the rotating hole 91. When the locking hole 92 on the mounting plate 9 and the adjusting hole 82 on the support plate 8 are in the alignment state, the mounting plate 9 can be fixed to the support plate 8 again with bolts, which facilitates the adjustment of the relative position of the cleaning part and the bearing plate 3.

[0038] Reference Figure 2 and Figure 3 The cleaning mechanism 5 also includes a drive motor 53, a coupling 54, and a main shaft 55. The main shaft 55 is rotatably supported on the mounting plate 9. The main shaft 55 is coaxially fixed with the cleaning component. The drive motor 53 is mounted on the mounting plate 9. The drive shaft of the coupling 54 is coaxially fixed with the output shaft of the drive motor 53. The driven shaft of the coupling 54 is coaxially fixed with the main shaft 55. The drive shaft and the driven shaft of the coupling 54 are locked together.

[0039] Specifically, the outer contour of the protective cover 52 is cylindrical and is fixedly connected to the mounting plate 9. The interior of the protective cover 52 is hollow to form a space for the cleaning component to rotate along the protective cover 52.

[0040] Meanwhile, the cleaning component can be a cleaning brush or a silicone soft brush to facilitate cleaning the surface of the support.

[0041] Furthermore, a bearing (not shown in the figure) is installed on the mounting base, the main shaft 55 is rotatably connected to the bearing, and the end of the main shaft 55 away from the driven shaft connected to the coupling 54 moves through the protective cover 52 and is fixedly connected to the cleaning component.

[0042] During installation, first fix the cleaning component coaxially with the main shaft 55. Then, insert the main shaft 55 with the cleaning component installed into the protective cover 52 and fix it coaxially with the bearing. The end of the main shaft 55 away from the cleaning component is fixed coaxially with the driven shaft of the coupling 54. This makes it easy to disassemble the cleaning component along the mounting plate 9 or install the cleaning component on the mounting plate 9.

[0043] Therefore, when the drive motor 53 is activated, the output shaft of the drive motor 53 drives the drive shaft of the coupling 54 to rotate synchronously with the output shaft of the drive motor 53, so as to drive the driven bearing main shaft 55, which is locked with the drive shaft of the coupling 54, to rotate along the mounting plate 9. At this time, the cleaning component and the bearing plate 3 are in abutting state, so as to achieve the purpose of cleaning the surface of the bearing plate 3.

[0044] Correspondingly, a rotation gap 7 is provided between the surface of the protective cover 52 facing the bearing plate 3 and the surface of the bearing plate 3 facing the protective cover 52, so as to avoid friction between the protective cover 52 and the bearing plate 3 when the bearing plate 3 rotates along the frame 1.

[0045] Meanwhile, the rotation gap 7 is set between 0.25mm and 1.00mm (SI units, millimeters). A negative pressure pipeline 6 is connected to the protective cover 52. In this embodiment, the negative pressure pipeline 6 is connected to a negative pressure generator. When the cleaning component cleans the surface of the carrier plate 3, the protective cover 52 is in a negative pressure state. The negative pressure is used to extract the particles located in the protective cover 52, thereby achieving the purpose of cleaning the particles on the surface of the carrier plate 3. Since the rotation gap 7 is between 0.25mm and 1.00mm, it helps to reduce the probability of secondary pollution of the carrier plate 3 caused by the particles being released to the outside of the protective cover 52 along the rotation gap 7 when the cleaning component cleans the carrier plate 3 due to the large distance between the protective cover 52 and the carrier plate 3. This plays a positive guiding role in reducing the amount of particles accumulating on the appearance inspection device 2.

[0046] The implementation principle of a cleaning device for workpiece appearance inspection equipment according to an embodiment of this application is as follows: The workpiece is placed in the limiting groove 31 of the bearing plate 3. The bearing plate 3 is driven by a servo motor to rotate along the frame 1, carrying the workpiece. The appearance inspection device 2 inspects the workpiece. At the same time, the drive motor 53 and the cleaning part are coaxially fixed by the main shaft 55 through the coupling 54. When the output shaft of the drive motor 53 rotates, it will drive the cleaning part to rotate along the surface of the bearing plate 3, thereby achieving the purpose of cleaning the surface of the bearing plate 3. After cleaning, the particles move randomly along the inside of the protective cover 52. The negative pressure pipe 6 makes the inside of the protective cover 52 negative pressure. The particles are drawn out along the negative pressure pipe 6 under the negative pressure, thereby achieving the purpose of cleaning the particles on the surface of the bearing plate 3. At the same time, a rotation gap 7 is preset between the protective cover 52 and the bearing plate 3 to avoid friction between the bearing plate 3 and the protective cover 52. It can also effectively solve the problem of particles in the protective cover 52 leaking out of the protective cover 52 to the bearing plate 3.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
