However, this CCD inspection instrument lacks a continuous workpiece loading function, which makes it impossible to achieve continuous automated inspection of batches of workpieces. Utility Model Content

[0005] To address the problem that existing CCD inspection instruments lack continuous workpiece feeding capabilities, hindering continuous automated inspection of batches of workpieces, this invention provides a CCD appearance inspection feeding machine. By driving a conveyor belt to perform circumferential rotation and intermittent pauses, it achieves continuous automated feeding and inspection of batches of workpieces.

The intermittent feeding system includes: a second rotating shaft, a turntable, a toothed belt, a motor frame, a motor, a third rotating shaft, and a half gear. Two sets of second rotating shafts are rotatably mounted on the front side wall of the worktable, corresponding to each other. Two sets of turntables are fixedly mounted on the two sets of second rotating shafts. The toothed belt is sleeved on the two sets of turntables, and its circumferential rotation is achieved by the circumferential rotation of the turntables. The motor frame is fixedly mounted below the worktable. The motor is mounted inside the motor frame. The third rotating shaft is connected to the output end of the motor. The half gear is fixedly mounted on the third rotating shaft and meshes with the outer wall of the toothed belt.

[0007] In the above technical solution, the second rotating shaft corresponds to and is coaxially arranged with the first rotating shaft, and is fixedly connected to the first rotating shaft.

[0008] The above technical solution also includes a limiting and locking assembly, which includes: a cylinder, a drive rod, a U-shaped limiting seat, and a limiting block. The cylinder is arranged vertically; the drive rod is installed vertically at the output end of the cylinder; the U-shaped limiting seat is fixedly installed on the top end of the drive rod and is configured as a U-shape; the limiting block is fixedly installed on one of the second rotating shafts and its shape is adapted to the U-shaped limiting seat.

[0009] The above technical solution also includes a signal transmission component, which includes: a blocking pin, a first mounting arm, a second mounting arm, a transmitter, and a receiver.

[0010] In the above technical solution, the inner cavity of the workbench is provided with an inclined guide seat, which is inclined towards the end of the workbench, and the highest point of the inclined guide seat is adjacent to the middle of the outer wall of the conveyor belt.

[0011] In the above technical solution, a testing machine is provided at the top center of the workbench, and the testing machine includes at least testing function, control function and display function.

[0012] In the above technical solution, the detection machine is electrically connected to the motor, transmitter, receiver, and cylinder respectively.

[0013] In the above technical solution, the blocking pin is rotatably disposed in the area between the transmitter and the receiver.

[0014] The CCD appearance inspection feeding machine of this utility model has the following advantages compared with the prior art: I. Addressing the technical pain point of existing CCD inspection instruments lacking continuous workpiece feeding functionality, which prevents the completion of continuous automated inspection of batch workpieces, this utility model achieves continuous automated feeding and inspection of batch workpieces by driving the conveyor belt to perform circumferential rotation and intermittent pause actions. Relying on the same feeding system, it simultaneously realizes the individual feeding and inspection of batch workpieces, accurately adapting to the CCD inspection scenario of batch workpieces, effectively achieving the goal of continuous inspection of batch workpieces, significantly improving inspection efficiency, and integrating conveying and inspection collaborative functions into the same equipment, eliminating the need for additional independent feeding mechanisms and simplifying the overall structure of the equipment; Second, in this utility model, by driving the half gear to rotate continuously in a circumferential direction, the toothed belt can be linked and the conveyor belt can be driven to achieve intermittent circumferential rotation. This transmission method, in conjunction with the inspection machine, can complete the automatic appearance inspection of the workpieces carried on the conveyor belt, and finally achieve a continuous inspection process. Compared with the solution of achieving intermittent rotation by frequently starting and stopping the conveyor belt itself, this design transforms the continuous rotation of the half gear into the intermittent motion of the conveyor belt, avoiding the mechanical impact caused by frequent starting and stopping of the conveyor belt, effectively reducing the wear of core components, and thus extending the overall service life of the equipment. Third, this utility model is additionally equipped with a locking mechanism, which is automatically triggered when the toothed belt stops rotating, and can rigidly lock the conveyor belt. This function can ensure that the conveyor belt remains completely stationary during the pause phase, preventing accidental rotation, so that the workpiece carried on the conveyor belt is precisely located directly below the detection area of ​​the inspection machine and is inspected in a static posture. This method avoids the problem of accidental displacement caused by inertia or slight external disturbances after the conveyor belt is disengaged from the drive, effectively preventing adverse effects such as detection field deviation and measurement data distortion caused by displacement, and ensuring the accuracy and reliability of the detection results. IV. In this utility model, by configuring core components such as a shielding pin, transmitter, and receiver, the displacement direction of the cylinder output end can be automatically adjusted according to the circumferential rotation of the half gear. Based on the change in the displacement direction of the cylinder, the U-shaped limit seat can be further controlled to switch between two adaptation states, namely, limiting or releasing the limit block; this linkage mechanism can achieve precise working condition adaptation: when the half gear and the toothed belt are in meshing state, the U-shaped limit seat releases the limit block, ensuring that the half gear can drive the toothed belt to operate normally; when When the half gear disengages from the toothed belt, the U-shaped limit seat automatically engages with the limit block and forms a limit. This method ensures that after the half gear disengages from the toothed belt, both the toothed belt and the conveyor belt linked to it remain stationary, effectively preventing accidental rotation in a non-drive state and significantly improving the limit stability after the conveyor belt rotates. This method requires no manual intervention or additional power triggering, and relies entirely on mechanical transmission logic to complete the working condition adaptation, greatly improving the automation level of equipment operation and reducing manual operation links and potential risks of misoperation. In summary, this invention utilizes the circumferential rotation and intermittent pauses of the conveyor belt to achieve continuous automated feeding and inspection of batch workpieces using a single feeding system. This significantly improves inspection efficiency, eliminates the need for a separate feeding mechanism, and simplifies the overall equipment structure. The continuous rotation of the half-gear is converted into the intermittent movement of the conveyor belt, replacing the frequent start-stop cycles of the conveyor belt itself. This avoids wear and tear on core components caused by mechanical impact, extending the equipment's lifespan. Simultaneously, it works in conjunction with the inspection machine to complete automatic visual inspection, ensuring continuous operation. When the toothed belt pauses, a locking mechanism is triggered to rigidly lock the conveyor belt, preventing accidental rotation and ensuring the workpiece is precisely positioned within the inspection area. This avoids inspection deviations and data distortion caused by displacement, ensuring accurate and reliable inspection results. Through the linkage of the blocking pin, transmitter, receiver, and half-gear, the U-shaped limit seat automatically controls the limiting state of the limit block, achieving precise adaptation of the working conditions when the half-gear and toothed belt engage or disengage. This improves the stability of the conveyor belt limit, eliminates the need for manual or additional power intervention, increases the automation level of the equipment, reduces the risk of operational errors, and comprehensively optimizes the batch inspection performance and operational reliability of the CCD inspection instrument.

[0016] The following are specific implementation cases and appendices. Figures 1 to 7 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0017] A CCD appearance inspection feeding machine includes a frame 1, a worktable 2 fixedly installed at the top of the frame 1, the worktable 2 being configured as a U-shaped trough structure, and also includes a conveying component and an intermittent feeding system. The conveying component is disposed in the inner cavity of the worktable 2 to realize the horizontal conveying of the workpiece; the intermittent feeding system is disposed on the front side of the worktable 2 to drive the conveying component to perform intermittent rotation. The intermittent feeding system includes: a second rotating shaft 8, a turntable 10, a toothed belt 11, a motor frame 12, a motor 13, a third rotating shaft 14, and a half gear 15. Two sets of second rotating shafts 8 are rotatably mounted on the front side wall of the worktable 2, corresponding to each other. Two sets of turntables 10 are fixedly mounted on the two sets of second rotating shafts 8. The toothed belt 11 is fitted onto the two sets of turntables 10, and its circumferential movement is achieved by the circumferential rotation of the turntables 10. In this invention, the rotation of the turntables 10 drives the toothed belt 11 to achieve circumferential movement. The rotation principle is the same as that of a conveyor belt driven by a rotating roller, which is a common power transmission method in the industry. The specific transmission structure can adopt two conventional schemes: First, power transmission is achieved by relying on the friction between the contact surfaces of the turntable 10 and the toothed belt 11, as long as the friction coefficient between the two meets the friction threshold required for driving; Second, meshing transmission is adopted, that is, teeth are set on the outer wall of the turntable 10 and corresponding teeth are set on the inner wall of the toothed belt 11, and power transmission is achieved through the meshing of the teeth. Regardless of the scheme adopted, as long as the core requirement of "stable driving of the toothed belt 11 to rotate synchronously in the circumferential direction when the turntable 10 rotates" is met, it is acceptable. Given that the above transmission principle and structure are existing mature technologies and not innovative improvements of this utility model, further details regarding their specific friction coefficient parameters, tooth specifications, assembly clearances, etc., will not be elaborated or limited here. The motor frame 12 is fixedly installed below the worktable 2. The motor 13 is installed inside the motor frame 12. The motor 13 uses a commercially available stepper motor, which has forward and reverse rotation functions. The output end can flexibly switch between forward and reverse rotation directions according to actual usage requirements to adapt to different driving needs under different working conditions. Given that its performance parameters and functions are existing mature technologies and fully meet the usage requirements of this application, no additional limitations or elaborations will be made regarding its specific power, speed, and other parameters. The third rotating shaft 14 is connected to the output end of the motor 13. The half gear 15 is fixedly installed on the third rotating shaft 14 and meshes with the outer wall of the toothed belt 11. Specifically, the conveying assembly includes: a first rotating shaft 5, rotating rollers 6, and a conveyor belt 7. Two sets of first rotating shafts 5 are arranged correspondingly in the inner cavity of the worktable 2; two sets of rotating rollers 6 are respectively fixedly installed on the two sets of first rotating shafts 5; and the conveyor belt 7 is sleeved on the two sets of rotating rollers 6. A second rotating shaft 8 is arranged coaxially with the first rotating shaft 5 and is fixedly connected to the first rotating shaft 5 to ensure that the rotation of the second rotating shaft 8 drives the first rotating shaft 5 to rotate coaxially, ensuring the accuracy of the driving force transmission. The first rotating shaft 5, rotating rollers 6, and conveyor belt 7 involved in this utility model are all common standard components of belt conveyors currently on the market, and their selection and application conform to industry norms. In terms of working principle, this set of components outputs power through the active rotation of the rotating rollers 6, which can directly drive the conveyor belt 7 to achieve synchronous operation, thereby completing the workpiece conveying function. This power transmission method and operating logic is a mature technology that is widely used in the belt conveyor field on the market, and the relevant technical solutions have stability and universality.Since the first rotating shaft 5, the rotating roller 6, and the conveyor belt 7 are not innovative improvements of this utility model, their specific dimensions, speed, load-bearing capacity, and other specifications are not further limited here, nor are their existing structural details and working principles described in detail.

[0018] The motor 13 drives the third shaft 14 and the half gear 15 to rotate clockwise synchronously. When the teeth on the half gear 15 rotate to mesh with the toothed belt 11, the toothed belt 11 is driven to rotate counterclockwise for a certain distance. During this process, the toothed belt 11 drives the turntable 10 and the second shaft 8 to rotate, which in turn drives the first shaft 5 to rotate through the second shaft 8, so that the roller 6 drives the conveyor belt 7 to rotate, and the conveyor belt 7 transports the workpiece during the rotation.

[0019] This invention utilizes the circumferential rotation and intermittent pauses of the conveyor belt 7 to achieve continuous automated feeding and inspection of batches of workpieces. The same feeding system synchronously completes the individual feeding and inspection of each workpiece in the batch, precisely matching the CCD inspection scenario for batch workpieces, successfully achieving continuous inspection of batch workpieces and significantly improving inspection efficiency. Furthermore, the equipment integrates the coordinated functions of conveying and inspection, eliminating the need for a separate feeding mechanism and simplifying the overall structure of the equipment.

[0020] In this invention, the continuous circumferential rotation of the half-gear 15 can link with the toothed belt 11, thereby driving the conveyor belt 7 to achieve intermittent circumferential rotation. This transmission method, in conjunction with the inspection machine 3, can automatically perform visual inspection of the workpieces on the conveyor belt 7, forming a continuous inspection process. Compared with the solution of frequently starting and stopping the conveyor belt 7 to achieve intermittent rotation, this design transforms the continuous rotation of the half-gear 15 into the intermittent motion of the conveyor belt 7, avoiding mechanical impact caused by frequent starting and stopping of the conveyor belt 7, reducing wear and tear on core components, and thus extending the overall service life of the equipment.

[0021] This solution also includes a limit locking assembly, which includes: a cylinder 18, a drive rod 19, a U-shaped limit seat 20, and a limit block 9. The cylinder 18 is arranged vertically; the drive rod 19 is installed vertically at the output end of the cylinder 18. The cylinder 18 used in this application is a commonly used self-locking cylinder on the market, whose output end can stop at any position and be locked. It only needs to meet the usage requirements of this application, and will not be described or limited here. The U-shaped limit seat 20 is fixedly installed on the top of the drive rod 19 and is set as a U-shaped structure. The limit block 9 is fixedly installed on one of the second rotating shafts 8 and its shape is adapted to the U-shaped limit seat 20.

[0022] This invention includes an additional locking mechanism that automatically activates when the toothed belt 11 stops rotating, creating a rigid lock on the conveyor belt 7. This design ensures that the conveyor belt 7 remains completely stationary during pauses, completely preventing accidental rotation. This allows the workpiece carried on the conveyor belt 7 to be precisely aligned directly below the inspection area of ​​the inspection machine 3, completing the inspection process in a static state. Fundamentally, this locking mechanism prevents the conveyor belt 7 from accidentally shifting due to its own inertia or slight external interference after disengaging from the drive, effectively preventing adverse consequences such as shifted inspection field of view and inaccurate measurement data caused by displacement, thus providing strong assurance for the accuracy and reliability of the inspection results.

[0023] This solution also includes a signal transmission assembly, which includes: a blocking pin 16, a first mounting arm 17, a second mounting arm 21, a transmitter 22, and a receiver 23. The blocking pin 16 is fixedly mounted on the half gear 15; the first mounting arm 17 is fixedly mounted below the worktable 2, and the cylinder 18 is mounted vertically on the first mounting arm 17; the second mounting arm 21 is fixedly mounted on the side wall of the first mounting arm 17; the transmitter 22 and the receiver 23 are mounted vertically on the rear side of the second mounting arm 21; the blocking pin 16 is rotatably disposed in the area between the transmitter 22 and the receiver 23.

[0024] The blocking pin 16 adopts a commercially available signal blocking pin. Its core function is to trigger signal state switching through position changes: when the blocking pin 16 enters the sensing area between the transmitter 22 and the receiver 23, it can physically block part of the signal between them. This blocking signal is transmitted to the built-in controller of the detection machine 3 for processing. After receiving the signal, the controller drives the output end of the cylinder 18 to move upward, thereby driving the U-shaped limit seat 20 to move upward and engage with the outer wall of the limit block 9, ultimately achieving stable positioning of the second rotating shaft 8, the rotating roller 6, and the conveyor belt 7. Conversely, when the blocking pin 16 leaves the area between the transmitter 22 and the receiver 23, the signal returns to the normal state. This normal signal is also transmitted to the built-in controller of the detection machine 3, which then controls the output end of the cylinder 18 to move downward, causing the U-shaped limit seat 20 to disengage from the limit block 9. This state clears the mechanical obstruction for the subsequent normal rotation of the toothed belt 11 and the conveyor belt 7, ensuring that the transmission system can smoothly enter the operating condition. The components and principles involved in the above signal detection, control logic and execution process are all based on existing mature technologies. Their core function is to achieve precise switching between limit state and operation state through the coordination of mechanical triggering and electronic control response.

[0025] In this invention, by configuring core components such as the blocking pin 16, transmitter 22, and receiver 23, the displacement direction of the output end of the cylinder 18 can be automatically adjusted according to the circumferential rotation of the half gear 15. This, in turn, controls the U-shaped limiting seat 20 to switch between two adaptive states based on the displacement change of the cylinder 18, thus limiting or releasing the limiting block 9. This linkage mechanism can precisely adapt to different working conditions: when the half gear 15 and the toothed belt 11 are engaged, the U-shaped limiting seat 20 releases the limiting block 9, ensuring normal drive of the toothed belt 11 by the half gear 15; when the half gear 15 disengages from the toothed belt 11, the U-shaped limiting seat 20 automatically engages the limiting block 9 and forms a limit. Ultimately, this mechanism ensures that after the half gear 15 disengages from the toothed belt 11, the toothed belt 11 and the conveyor belt 7 linked to it remain stationary, avoiding accidental rotation in a non-driven state and significantly improving the limiting stability of the conveyor belt 7 after rotation. Moreover, the entire process requires no manual intervention or additional power triggering, relying entirely on mechanical transmission logic to complete the working condition adaptation, effectively improving the automation level of equipment operation and reducing manual operation links and potential risks of misoperation.

[0026] The inner cavity of the workbench 2 is provided with an inclined guide seat 4. The inclined guide seat 4 is inclined towards the end of the workbench 2, and the highest point of the inclined guide seat 4 is adjacent to the middle of the outer wall of the conveyor belt 7. The workpiece after being detected by the conveyor belt 7 is transported to the edge of the conveyor belt 7 and can slide down along the inclined end surface of the inclined guide seat 4 to realize the unloading of the workpiece.

[0027] Specifically, an inspection machine 3 is installed at the top center of the workbench 2. The inspection machine 3 includes at least inspection, control, and display functions. The inspection machine 3 is electrically connected to the motor 13, transmitter 22, receiver 23, and cylinder 18. The inspection machine 3 involved in this utility model is the standard inspection host of an existing CCD inspection instrument, and it has its own controller and display screen structure. The inspection host needs to meet the basic functional requirements, that is, it has the ability to inspect workpiece appearance-related parameters, such as size, defects, and flatness, and it needs to work in conjunction with the matching controller and display screen to realize the setting of inspection parameters, control of the inspection process, and visualization of inspection results. It should be noted that the structural composition, core inspection principle, parameter configuration method of the controller, and display logic of the screen of the inspection machine 3 itself are all within the scope of existing mature technologies, such as using the same inspection host in the BBA-9111JC customized CCD vision inspection equipment on the market. Since it is not an innovative improvement point of this utility model, its specific technical details will not be elaborated here, nor will any additional limitations be made on its existing technical features.

[0028] In addition, in this application, the batch loading operation of workpieces can be achieved in two ways: one is manual placement, and the other is automatic placement using a commercially available gripping and placing robot. Both methods require each workpiece to be precisely placed onto the conveyor belt 7, and then, in conjunction with the circumferential rotation and intermittent pauses of the conveyor belt 7, the batch of workpieces can be transported one by one to the area directly below the inspection machine 3 for inspection. The placement timing of two adjacent workpieces can be matched and set according to the frequency of the intermittent circumferential rotation of the conveyor belt 7. Since the intermittent rotation frequency of the conveyor belt 7 is determined by the circumferential rotation frequency of the half-gear 15, the workpiece placement timing can be further flexibly adjusted according to the rotation frequency of the half-gear 15. All the above parameter settings are completed through the matching controller of the inspection machine 3, and the parameter setting methods and core components involved all adopt existing mature technologies. Their specific structures and operating logic are not further elaborated or limited here.

[0029] The working principle of a CCD appearance inspection feeding machine in this embodiment is as follows: Using manual operation or a robotic arm for material handling, workpieces are placed in batches and at equal intervals on the running conveyor belt 7. A motor 13 drives the third shaft 14 and half-gear 15 to rotate synchronously clockwise. When the teeth on the half-gear 15 mesh with the toothed belt 11, the toothed belt 11 rotates counterclockwise a certain distance. During this process, the toothed belt 11 drives the turntable 10 and the second shaft 8 to rotate, which in turn drives the first shaft 5 to rotate, thus enabling the roller 6 to rotate the conveyor belt 7. The conveyor belt 7 transports the workpiece during rotation until the half gear 15 rotates until its teeth disengage from the toothed belt 11. At this time, the blocking pin 16 on the half gear 15 follows the rotation of the half gear 15 and enters between the receiver 23 and the transmitter 22. The transmitter 22 and the receiver 23 transmit the blocking signal information of the blocking pin 16 to the detection machine 3 for processing. The controller of the detection machine 3 controls the output end of the cylinder 18 to move upward, driving the drive rod 19 and the U-shaped limit seat 20 upward. The U-shaped limit seat 20 is inserted into the limit block. The outer side of the limit block 9 is engaged to limit its rotation, preventing it from rotating. This stabilizes the second rotating shaft 8, turntable 10, and toothed belt 11, thereby stabilizing the first rotating shaft 5, roller 6, and conveyor belt 7. During this pause in the conveyor belt 7's rotation, the workpiece on the conveyor belt 7 and below the inspection machine 3 is visually inspected. After inspection, the half-gear 15 drives the blocking pin 16 to continue rotating until the blocking pin 16 disengages from the area between the transmitter 22 and receiver 23. The signal is then transmitted to the inspection unit. Machine 3 controls the downward movement of the output end of cylinder 18, causing the U-shaped limit seat 20 to disengage from the limit block 9; at the same time, the half gear 15 accurately and re-engages on the toothed belt 11, and with the continued rotation of the half gear 15, the toothed belt 11 rotates for the next cycle, so that the inspected workpiece leaves the inspection machine 3 and the next workpiece to be inspected enters the inspection machine 3, realizing the automated inspection of batch workpieces; if there is a defective workpiece, the display of the inspection machine 3 will show it, and the workpiece can be manually sorted out.

[0030] This invention utilizes the circumferential rotation and intermittent pauses of the conveyor belt 7 to achieve continuous automated feeding and inspection of batch workpieces using a single feeding system. This significantly improves inspection efficiency and eliminates the need for a separate feeding mechanism, simplifying the overall equipment structure. The continuous rotation of the half-gear 15 is converted into the intermittent motion of the conveyor belt 7, replacing the frequent start-stop of the conveyor belt 7 itself. This avoids wear and tear on core components caused by mechanical impact, extending the equipment's service life. Simultaneously, it works in conjunction with the inspection machine 3 to complete automatic visual inspection, ensuring continuous operation. When the toothed belt 11 pauses, it triggers a locking mechanism to lock the conveyor belt 7. The system features a locking mechanism to prevent accidental rotation, ensuring the workpiece is precisely positioned within the detection area. This avoids detection deviations and data distortions caused by displacement, guaranteeing accurate and reliable detection results. Through the linkage of the blocking pin 16, transmitter 22, receiver 23, and half gear 15, the system automatically controls the limiting state of the U-shaped limit seat 20 on the limit block 9. This achieves precise adaptation of the working conditions when the half gear 15 engages or disengages from the toothed belt 11, improving the limiting stability of the conveyor belt 7. It also eliminates the need for manual or additional power intervention, increasing the automation level of the equipment, reducing the risk of operational errors, and comprehensively optimizing the batch detection performance and operational reliability of the CCD detector.
