Description

Technical Field

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

[0002] For mass-produced workpieces, after the initial production is completed, it is usually necessary to inspect their appearance and dimensions to ensure that the workpieces can meet the design and usage requirements.

[0003] For example, a ceramic workpiece needs to be produced with a diameter of φ8.1mm~φ8.2mm and a height of 12.2mm~14.8mm. Due to the material properties and usage requirements, the appearance and size of the workpiece are subject to high standards. Therefore, it is necessary to use appearance inspection equipment to inspect each workpiece individually, thereby separating workpieces with problems such as unqualified dimensions, cracks, missing pieces, or bulging cross-sections (collectively referred to as unqualified workpieces) from qualified workpieces.

[0004] In existing equipment for workpiece appearance inspection, a straight feeding line is usually used, which includes a conveying mechanism and workpiece appearance inspection equipment. The conveying mechanism includes a straight feeding belt, and the workpiece appearance inspection equipment includes several sets of inspection components. These inspection components are arranged sequentially along the conveying direction of the feeding belt, and the controller controls the inspection components to work together to complete the workpiece appearance inspection.

[0005] The problem with this type of feeder belt is that the large number of detection components results in a long overall length of the feeder belt, which makes the production site relatively cramped after installation, leaving room for improvement. Utility Model Content

[0006] The purpose of this invention is to facilitate the transport of the workpiece to be inspected to the inspection assembly for inspection, and to quickly unload the workpiece along the inspection assembly after inspection.

[0007] To achieve the above objectives, the present application provides a conveying device for a workpiece appearance inspection equipment, which adopts the following technical solution:

[0008] A conveying device for a workpiece appearance inspection equipment includes a frame and a support plate rotatably supported on the frame. A feeding mechanism, an inspection component, and a discharging mechanism are sequentially arranged on the frame near the support plate. The feeding mechanism includes a conveying component and an adjusting component. The conveying component includes a conveyor frame and a feeding belt rotatably supported on the conveyor frame. The adjusting component includes a main stop bar and an adjusting plate. The main stop bar and the adjusting plate are arranged in the same direction as the feeding belt on the conveyor frame, forming a material passage for workpieces to pass through. The distance between the main stop bar and the adjusting plate is adjustable. The material passage is connected to the support plate. The discharging mechanism includes a discharging frame arranged tangentially to the rotation of the support plate and a discharging belt rotatably supported on the discharging frame. The plane of the discharging belt along the frame is lower than the plane of the support plate along the frame.

[0009] Preferably, a limiting groove is formed on the surface of the bearing plate in the circumferential direction, and the material passage and the feeding belt are both connected to the limiting groove.

[0010] Preferably, the adjustment assembly further includes an adjustment member, one end of which is fixedly connected to the conveyor frame, and the end of the adjustment member away from the connection with the conveyor frame is provided with a first waist-shaped groove. The adjustment plate and the adjustment member are fixedly connected by bolts through the first waist-shaped groove.

[0011] Preferably, the material passage is provided with an arc-shaped transition section near the bearing plate, and the arc-shaped transition section is formed by the main baffle and the adjusting plate bending towards the limiting groove.

[0012] Preferably, the feeding mechanism further includes a limiting component, which includes a first limiting baffle and a second limiting baffle. The first limiting baffle and the second limiting baffle are disposed on the feeding frame along the feeding belt conveying direction, and a feeding channel is formed between the first limiting baffle and the second limiting baffle. An avoidance gap is provided between the end of the first limiting baffle and the second limiting baffle near the bearing plate and the feeding belt, and the bearing plate rotates along the avoidance gap.

[0013] Preferably, the end of the unloading rack closest to the support plate is inclined downwards from the end furthest from the support plate.

[0014] Preferably, the feeding mechanism further includes an auxiliary feeding component, which includes an adjusting frame and a pneumatic pipeline. The adjusting frame is located at the end of the feeding frame away from the support plate, and the pneumatic pipeline is located on the adjusting frame and faces the feeding belt.

[0015] Compared with the prior art, the present invention provides a conveying device for workpiece appearance inspection equipment, which has the following beneficial effects:

[0016] 1. Because the carrier plate rotates on the frame, and detection components are installed along the frame at the carrier plate, the detection components can detect the workpiece as it rotates along the frame. This design features high integration. The main baffle and adjusting plate work together to limit the path of the workpiece along the feed belt to the carrier plate, ensuring a smooth arrival. The adjustable distance between the adjusting plate and the main baffle allows for adjustment of the width of the material passage between them, accommodating workpieces of different diameters transported along the feed belt to the carrier plate. The carrier tray is highly versatile. When the workpiece reaches the unloading belt after inspection, it separates from the carrier tray along the tangent of the tray's rotation. Since the plane of the unloading belt along the frame is lower than the plane of the carrier tray as it rotates along the frame, the workpiece separated from the carrier tray falls onto the unloading belt by gravity. Through the above process, the entire process of workpiece loading, inspection, and unloading can be realized on the frame. This plays a positive guiding role in the convenience of transporting the workpiece to be inspected to the inspection component for inspection and the rapid unloading of the inspected workpiece along the inspection component.

[0017] 2. By limiting the path of the workpiece along the carrier plate through the limiting groove, the workpieces fed to the carrier plate along the feeding belt can pass through the detection component in an orderly manner for detection, which effectively solves the problem of inaccurate detection results of the detection component caused by the workpiece not being placed in a fixed position along the carrier plate.

[0018] 3. When the workpiece reaches the first and second baffles after the inspection is completed, the bearing plate rotates along the clearance gap. Due to the blocking effect of the first and second baffles, the workpiece is separated from the bearing plate and falls onto the feed belt by the power of the bearing plate rotation.

[0025] First, it should be noted that the detection component 4 described in this embodiment is used to inspect the appearance of the workpiece. It includes an image acquisition module, which acquires images of the workpiece surface and sends the acquired images to the controller. The controller's built-in program determines whether the workpiece is a qualified workpiece. The controller can be a host computer, which consists of hardware, software, and monitoring configuration software. It interacts with the feeding mechanism 3, the detection component 4, and the unloading mechanism 5 through a communication link, realizing a centralized and intelligent system. The specific composition and working principle of the detection component 4 and the controller are not described in detail here.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a conveying device for a workpiece appearance inspection equipment. (Refer to...) Figure 1 , Figure 2 as well as Figure 3A conveying device for a workpiece appearance inspection equipment includes a frame 1 and a support plate 2 rotatably supported on the frame 1. A feeding mechanism 3, an inspection component 4, and a discharging mechanism 5 are sequentially arranged on the frame 1 near the support plate 2. The feeding mechanism 3 includes a conveying component 31 and an adjusting component 32. The conveying component 31 includes a conveyor frame 311 and a feeding belt 312 rotatably supported on the conveyor frame 311. The adjusting component 32 includes a main baffle 321 and an adjusting plate 322. 2 is arranged in the same direction as the feeding belt 312 on the conveyor frame 311. A material passage 6 is formed between the main baffle 321 and the adjusting plate 322, which allows the workpiece to pass through. The distance between the main baffle 321 and the adjusting plate 322 is adjustable. The material passage 6 is connected to the bearing plate 2. The unloading mechanism 5 includes an unloading frame 51 arranged in the tangential direction when the bearing plate 2 rotates and an unloading belt 52 rotatably supported on the unloading frame 51. The plane of the unloading belt 52 along the frame 1 is lower than the plane of the bearing plate 2 when it rotates along the frame 1.

[0028] Specifically, the frame 1 has a pre-set disk mounting position 11, and a first servo motor (not shown in the figure) is installed on the frame 1 at the disk mounting position 11. The output shaft of the first servo motor is fixed coaxially with the bearing disk 2, thereby realizing the purpose of the first servo motor driving the bearing disk 2 to rotate along the frame 1.

[0029] Furthermore, a mounting base 12 is installed on the frame 1, and the conveyor frame 311 is installed on the mounting base 12 in a parallel spatial relationship with the surface of the frame 1 facing the bearing plate 2, thereby achieving a stable connection between the conveyor frame 311 and the frame 1.

[0030] Meanwhile, several fixing plates 13 are installed at intervals on the side wall of the conveyor frame 311 along its length. The main baffle 321 is fixedly connected to the end of the fixing plate 13 away from the conveyor frame 311 by bolts. The fixing plate 13 makes the main baffle 321 stand above the feeding belt 312 to avoid sliding friction between the feeding belt 312 and the main baffle 321 when the feeding belt 312 rotates along the conveyor frame 311, so that the feeding belt 312 can rotate stably along the conveyor frame 311.

[0031] Correspondingly, the adjustment assembly 32 also includes an adjustment member 323. One end of the adjustment member 323 is fixedly connected to the conveyor frame 311. The end of the adjustment member 323 away from the conveyor frame 311 is provided with a first waist-shaped groove 3231. The adjustment plate 322 and the adjustment member 323 are fixedly connected by bolts through the first waist-shaped groove 3231.

[0032] Among them, reference Figure 3 , Figure 4 as well as Figure 5Several adjusting components 323 are provided. Several adjusting components 323 are installed at intervals along the length direction of the conveyor frame 311 on the side wall away from the fixed plate 13. Since the shape of several adjusting components 323 and their matching relationship with the conveyor frame 311 are the same, the matching relationship between one adjusting component 323, the conveyor frame 311 and the adjusting plate 322 will be described in detail below.

[0033] Specifically, the cross-sectional shape of the adjusting member 323 is L-shaped and is fixed to the side wall of the conveyor frame 311 by bolts. The first waist-shaped groove 3231 is opened along the width direction of the adjusting member 323. Therefore, when it is necessary to adjust the width of the material passage 6, simply loosen the bolts to adjust the relative position of the adjusting plate 322 along the adjusting member 323 through the first waist-shaped groove 3231. This is to adjust the width of the material passage 6 formed between the adjusting plate 322 and the main baffle 321, so as to enable workpieces of different diameters to move along the material passage 6 through the feeding belt 312 to the bearing plate 2.

[0034] Furthermore, a limiting groove 21 is formed on the circumferential surface of the bearing plate 2, and the material passage 6 and the unloading belt 52 are both connected to the limiting groove 21. The limiting groove 21 is formed by the bearing plate 2 being recessed along the thickness direction, and the cross-sectional profile of the limiting groove 21 is set in a V shape to adapt to the support requirements of workpieces of different diameters. When the workpiece passes through the material passage 6 and reaches the limiting groove 21, the limiting groove 21 supports the workpiece, improving the stability of the bearing plate 2 when supporting the workpiece and rotating along the frame 1, and preventing the workpiece from undergoing secondary displacement when the bearing plate 2 supports the workpiece and rotates along the frame 1 after it reaches the bearing plate 2.

[0035] Meanwhile, an arc-shaped transition section 7 is provided near the bearing plate 2 in the material passage 6, and the arc-shaped transition section 7 is connected to the limiting groove 21. The arc-shaped transition section 7 is formed by the main baffle 321 and the adjusting plate 322 bending towards the limiting groove 21. During the process of transporting the workpiece to the bearing plate 2 along the material passage 6 by the feeding belt 312, the feeding belt 312 carries the workpiece and moves in a straight line along the conveyor frame 311. When the workpiece reaches the arc-shaped transition section 7, the main baffle 321 and the adjusting plate 322 cooperate to make the workpiece move along the feeding belt 312. The movement path changes. At the instant the workpiece separates from the feed belt 312, the workpiece is subjected to the inertia of the feed belt 312 during the conveying process, and the pushing action of another workpiece adjacent to the current workpiece on the feed belt 312, so that the workpiece can smoothly reach the bearing plate 2. Furthermore, because the arc transition section 7 is connected to the limiting groove 21, the workpiece can directly reach the limiting groove 21 after separating from the feed belt 312, so as to avoid the workpiece moving randomly along the bearing plate 2 after separating from the feed belt 312.

[0036] Reference Figure 3 and Figure 4The feeding mechanism 5 also includes a limiting component 53, which includes a first limiting baffle 531 and a second limiting baffle 532. The first limiting baffle 531 and the second limiting baffle 532 are arranged on the feeding frame 51 along the conveying direction of the feeding belt 52. A feeding channel 8 is formed between the first limiting baffle 531 and the second limiting baffle 532. An avoidance gap 9 is provided between the end of the first limiting baffle 531 and the second limiting baffle 532 near the bearing plate 2 and the feeding belt 52. The bearing plate 2 rotates along the avoidance gap 9.

[0037] Specifically, the unloading rack 51 is installed on the frame 1 near the mounting base 12, and the unloading rack 51 and the conveyor rack 311 are arranged perpendicular to each other in spatial position to improve the space utilization of the frame 1.

[0038] Furthermore, the first limiting baffle 531 and the second limiting baffle 532 are fixed to the unloading frame 51 by bolts. The width of the unloading channel 8 formed by the first limiting baffle 531 and the second limiting baffle 532 is greater than the diameter of the workpiece, and the unloading channel 8 is connected to the limiting groove 21, so that the workpiece after being detected by the detection component 4 can quickly reach the unloading belt 52 along the bearing plate 2.

[0039] In contrast, when the workpiece after inspection is unloaded through the unloading channel 8 formed by the cooperation of the first limiting baffle 531 and the second limiting baffle 532, the workpiece needs to be separated from the carrier plate 2 along the tangential direction of the rotation of the carrier plate 2. Therefore, an clearance gap 9 is provided between the first limiting baffle 531 and the second limiting baffle 532 and the carrier plate 2. The clearance gap 9 is formed by the first limiting baffle 531 and the second limiting baffle 532 being recessed along the thickness direction at one end facing the carrier plate 2.

[0040] Therefore, when the bearing plate 2 rotates along the frame 1, the bearing plate 2 will rotate along the clearance gap 9. When the workpiece reaches the unloading channel 8 formed by the first limit baffle 531 and the second limit baffle 532, the movement path of the workpiece located on the limit groove 21 is forcibly changed by the cooperation of the first limit baffle 531 and the second limit baffle 532, so as to force the workpiece located on the limit groove 21 to separate from the bearing plate 2. The workpiece after being separated along the bearing plate 2 is subjected to inertial force and the thrust applied by the workpiece adjacent to the current workpiece, so that the workpiece quickly reaches the unloading channel 8, reducing the probability of the workpiece being unable to reach the unloading channel 8 due to the excessive gap at the connection between the unloading channel 8 and the bearing plate 2.

[0041] Correspondingly, the end of the unloading rack 51 closest to the support plate 2 is inclined downwards from the end furthest from the support plate 2. The unloading rack 51 is located between the frame 1 and the conveyor frame 311, and the end of the unloading rack 51 furthest from the support plate 2 is inclined towards the surface of the frame 1. Thus, after the workpiece reaches the unloading belt 52, the rotation of the unloading belt 52 drives the workpiece away from the support plate 2 along the unloading belt 52. Simultaneously, because the unloading rack 51 is in an inclined state, the workpiece's own weight is utilized, which helps improve the unloading efficiency of the workpiece.

[0042] In addition, the feeding mechanism 5 also includes an auxiliary feeding component 10, which includes an adjusting frame 101 and a pneumatic pipeline 102. The adjusting frame 101 is located at the end of the feeding frame 51 away from the bearing plate 2, and the pneumatic pipeline 102 is located on the adjusting frame 101 and faces the feeding belt 52.

[0043] The adjusting frame 101 has an L-shaped outline and is fixed to the side wall of the unloading frame 51 by bolts. A second waist-shaped groove 1011 is provided at the connection between the adjusting frame 101 and the unloading frame 51. The second waist-shaped groove 1011 is opened along the height direction of the adjusting frame 101. Thus, the adjusting frame 101 can be fastened to the unloading frame 51 by bolts through the second waist-shaped groove 1011, and the angle between the adjusting frame 101 and the unloading frame 51 and the height between the adjusting frame 101 and the unloading frame 51 can be adjusted.

[0044] Furthermore, a transverse adjustment groove 1012 is provided at the end of the adjustment frame 101 away from the end connected to the unloading frame 51. An installation block 10121 is installed in the transverse adjustment groove 1012. The pneumatic pipeline 102 is installed in the installation block 10121 by bolts. At the same time, the installation block 10121 is fixed in the transverse adjustment groove 1012 by bolts. The purpose of adjusting the installation block 10121 along the transverse position of the adjustment frame 101 can be achieved through the transverse adjustment groove 1012.

[0045] Correspondingly, the pneumatic pipeline 102 is connected to an external air source (such as an air compressor), and the air outlet of the pneumatic pipeline 102 is directed toward the end of the feed belt 52 away from the bearing plate 2.

[0046] Therefore, when the workpiece reaches the adjusting frame 101 along the feeding belt 52, the pneumatic pipeline 102 blows air onto the workpiece located on the feeding belt 52, which can quickly separate the workpiece from the feeding belt 52. At the same time, it can also clean the surface of the workpiece after inspection. Furthermore, for some workpieces that fall from the bearing plate 2 onto the feeding belt 52 and are in an upright position, after reaching the pneumatic pipeline 102, the air blown out by the pneumatic pipeline 102 can blow the workpiece down, thereby making the workpiece lie flat on the feeding belt 52.

[0047] Furthermore, it should be noted that in this embodiment, the feeding belt 312 and the unloading belt 52 are driven by servo motor drive modules, so that the feeding belt 312 can rotate smoothly along the conveyor frame 311 and the unloading belt 52 can rotate smoothly along the unloading frame 51. The servo motor drive module is a conventional drive component in the mechanical field, and its specific composition and working principle will not be described in detail here.

[0048] The implementation principle of a conveying device for a workpiece appearance inspection equipment according to an embodiment of this application is as follows: the conveying channel 6 formed between the main baffle 321 and the adjusting plate 322 limits the conveying path of the workpiece along the feeding belt 312, and the width of the conveying channel 6 can be adjusted by the adjusting member 323 to adapt to the conveying requirements of workpieces with different diameters. When the workpiece reaches the arc-shaped transition section 7, the arc-shaped transition section 7 forces the workpiece to change its movement path. Because the arc-shaped transition section 7 is connected to the limiting groove 21, the workpiece can smoothly reach the bearing plate 2. After the workpiece reaches the bearing plate 2, the bearing plate 2 carries the workpiece and rotates along the frame 1. When the workpiece reaches the detection component 4, the detection component 4 acquires an image of the workpiece and sends it to the controller to achieve the purpose of inspecting the appearance of the workpiece. After the inspection is completed, the workpiece continues to... As the workpiece on the support plate 2 moves, when it reaches the unloading channel 8, the workpiece in the limiting groove 21 is forced to separate from the support plate 2 by the first limiting baffle 531 and the second limiting baffle 532. As the support plate 2 rotates along the clearance gap 9, the workpiece on the support plate 2 falls directly onto the unloading belt 52 when it reaches the unloading channel 8. Since the unloading belt 52 is inclined, the workpiece moves quickly along the unloading belt 52 by the power of the unloading belt 52 itself and the gravity of the workpiece. When the workpiece reaches the adjusting frame 101, it is pushed by the pneumatic pipe 102 and falls quickly along the unloading belt 52. This plays a positive guiding role in the convenience of lifting and transporting the workpiece to be inspected to the inspection component 4 for inspection, and in the convenience of quickly unloading the inspected workpiece along the inspection component 4.

[0049] 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.
