Description

Technical Field

[0001] This invention relates to the field of diaphragm sorting technology, and more particularly to a diaphragm sorting optical inspection and feeding mechanism. Background Technology

[0002] Currently, the mainstream sorting and inspection technologies for materials on top of blue film include two types: machine vision appearance sorting and near-infrared spectroscopy material sorting. When performing optical sorting and inspection of materials, the blue film carrying the material and its frame are positioned by a feeding mechanism. The position information of the material can be identified by a vision recognition device, and the material at the corresponding position can be picked up by a gripping mechanism and sent to the subsequent inspection station to achieve sorting and inspection operations.

[0003] The existing film sorting optical inspection equipment has a fixed inner diameter for the film frame of the feeding mechanism, which is compatible with a single specification of blue film carrier frame. However, in actual production, there are many different sizes and models of blue film frames to be processed. When the equipment performs feeding and positioning operations for blue film frames of different specifications, it can only replace the film frame with one that is completely compatible with the corresponding blue film frame specification to complete the assembly and debugging. Frequent replacement of film frame not only prolongs the production line changeover and debugging time and significantly reduces the overall sorting and inspection efficiency, but also creates assembly gaps due to repeated disassembly and assembly of positioning parts, affecting the feeding and positioning accuracy of the blue film carrier tray. This, in turn, interferes with the detection benchmarks of subsequent film optical imaging and infrared spectroscopy detection, which can easily cause deviations in film sorting and inspection data, resulting in poor practicality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a film sorting optical inspection feeding mechanism, which solves the problem mentioned in the background art that the inner diameter of the film frame of the feeding mechanism of existing film sorting optical inspection equipment is a fixed size, and the compatible blue film support frame has a single specification.

[0007] Furthermore, the positioning block has a frame support plate on its side, and the top surface of the frame support plate and the top surface of the supporting block are in the same plane.

[0008] Furthermore, a drive worm is provided outside the shaft of the drive motor, and a drive worm wheel is provided outside the drive rod, with the drive worm and the drive worm wheel being connected by transmission.

The device is flexible and convenient to use, improving its flexibility, adaptability, and practicality. Attached Figure Description

[0034] Please refer to Figures 1 to 15 Example 1: This invention proposes a film sorting and optical inspection feeding mechanism, comprising: a moving component 1 and a tray assembly 2. The moving component 1 includes a connecting seat 101, an X-axis moving module 102, and a Y-axis moving module 103. The connecting seat 101 is fixedly installed on the film optical inspection worktable, and the X-axis moving module 102 is fixedly installed on the top of the connecting seat 101, and the Y-axis moving module 103 is fixedly installed on the top of the moving seat of the X-axis moving module 102. The tray assembly 2 includes a film holder positioning frame 201, which is fixedly installed on the top of the moving seat of the Y-axis moving module 103.

[0035] The specific usage and function of this embodiment are as follows: When a feeding operation is required, the blue film frame is placed inside the film frame positioning frame 201. After the blue film frame is placed inside the film frame positioning frame 201, it can be supported by the film frame positioning frame 201. After the blue film frame is locked with screws, the subsequent sorting and inspection operation can be carried out. The visual recognition equipment can identify information such as the position of the material on the top of the blue film. The X-axis moving module 102 and the Y-axis moving module 103 can drive the film frame positioning frame 201 to move in the X-axis and Y-axis directions. After the material to be inspected is moved to the appropriate position, the bottom lifting module can lift the material at the corresponding position, and the upper gripping mechanism can adsorb and grab the material at that position through the vacuum suction cup and send it to the subsequent sorting and inspection station. It is convenient and flexible to use.

[0036] In Example 2, based on Example 1, a film sorting optical inspection feeding mechanism further includes a control component, which consists of a positioning mechanism 3 and a support mechanism 4. The tray assembly 2 also includes a synchronization disk 202 and a positioning block 203. The synchronization disk 202 is rotatably connected to the outside of the film frame positioning frame 201, and the positioning block 203 is inserted into the inside of the film frame positioning frame 201 along the radial direction of the synchronization disk 202. The positioning mechanism 3 includes a drive motor 301, a drive rod 302, a force-applying block 303, and a connecting block 304. The drive motor 301 is fixedly installed on the top of the membrane frame positioning frame 201, and the drive rod 302 is rotatably connected to the inside of the membrane frame positioning frame 201. The force-applying block 303 is inserted into the inside of the membrane frame positioning frame 201, and the connecting block 304 is inserted into the inside of the membrane frame positioning frame 201, with the force-applying block 303 inserted into the side of the connecting block 304. The supporting mechanism 4 includes an electric push rod 401, a lifting seat 402, and a supporting block 403. The electric push rod 401 is fixedly installed on the bottom of the membrane frame positioning frame 201, and the lifting seat 402 is fixedly installed on the bottom end of the push rod of the electric push rod 401. The supporting block 403 is rotatably connected to the inside of the lifting seat 402.

[0037] The positioning block 203 and the support block 403 are each provided in three parts, and the number is not limited to three. The positioning block 203 and the support block 403 are evenly arranged along the circumference of the synchronous disk 202, and the positioning block 203 and the support block 403 are staggered with each other. The connecting block 304 is fixedly connected to the side of one of the positioning blocks 203. This design can achieve accurate positioning of the blue film frame.

[0038] The positioning block 203 has a frame support plate 2031 on its side, and the top surface of the frame support plate 2031 and the top surface of the support block 403 are in the same plane. This design allows the frame support plate 2031 to support and hold the bottom of the blue film frame when positioning and clamping it.

[0039] The drive motor 301 has a drive worm gear on its outer shaft and a drive worm wheel on its outer side. The drive worm gear and the drive worm wheel are connected by a transmission. The drive rod 302 has a helical drive groove 3021 on its outer side and a drive protrusion 3031 inside the force application block 303. The drive protrusion 3031 is inserted into the drive groove 3021. This design allows the positioning mechanism 3 to change the effective inner diameter of the carrier plate assembly 2, thereby realizing the rapid loading and positioning of blue film frames of different specifications. It is flexible and convenient to use.

[0040] The force-applying block 303 has a distance sensor 3033 on its side, which can monitor the distance between the force-applying block 303 and the connecting block 304. The connecting block 304 has an integral stop bar 3041 on its side, which is inserted into the force-applying block 303. The force-applying block 303 has a force-applying top spring 3032 on its side, with both ends of the top spring 3032 abutting against the sides of the force-applying block 303 and the connecting block 304, respectively. In use, the distance sensor 3033 can monitor the distance between the force-applying block 303 and the connecting block 304. The distance between the force-applying block 303 and the connecting block 304 is monitored in real time. The distance between the force-applying block 303 and the connecting block 304 is the degree of compression of the force-applying top spring 3032, that is, the clamping force of the positioning block 203 on the blue film frame. When the distance sensor 3033 detects that the distance between the force-applying block 303 and the connecting block 304 is at the set value, the drive motor 301 automatically turns off the power and will not continue to drive the force-applying block 303 to move. Thus, the positioning block 203 can maintain the current clamping force to position the blue film frame, and the use is stable.

[0041] The synchronous disk 202 has an arc-shaped synchronous groove 2021 inside, and the bottom of the positioning block 203 has a synchronous rod 2032. The synchronous rod 2032 is inserted into the synchronous groove 2021. This design enables the three positioning blocks 203 to move synchronously, and the positioning is fast and accurate.

[0042] The bottom of the film frame positioning frame 201 is provided with a flip rack 2011, and the outside of the rotating shaft of the support block 403 is provided with a flip gear 4031. The gear teeth of the flip gear 4031 and the flip rack 2011 mesh and drive each other. This design allows the support mechanism 4 to initially support the blue film frame before the carrier plate assembly 2 during material loading, avoiding the phenomenon that the blue film frame will fall off due to the initial inner diameter of the carrier plate assembly 2 being too large. After the carrier plate assembly 2 has positioned the blue film frame, the support block 403 can flip downward to avoid interference with the bottom space of the blue film frame, making it convenient for subsequent lifting operations of the material on top of the blue film from the bottom. It is flexible and convenient to use.

[0043] The specific usage and function of this embodiment are as follows: In this invention, during the loading operation, the blue film frame is first placed inside the film frame positioning frame 201. The supporting mechanism 4 can provide initial support for the blue film frame before the carrier plate assembly 2, preventing the blue film frame from falling due to the initial inner diameter of the carrier plate assembly 2 being too large. When the electric push rod 401 is in the retracted state, the supporting block 403 is used in a horizontal state, so that the top plane of the supporting block 403 can support and hold the blue film frame, thereby facilitating subsequent positioning, clamping, and other operations of the blue film frame. The positioning mechanism 3 drives the carrier plate assembly 2 to achieve the positioning and loading operation of the blue film frame. When the drive motor 301 rotates, the drive worm can drive the drive rod 302 to rotate through the drive worm wheel. When the drive rod 302 rotates, the drive groove 3021 can drive the force-applying block 303 to move through the drive protrusion 3031. Under the cooperation of the integral stop rod 3041 and the force-applying top spring 3032, the force-applying block 303 and the connecting block 304 are used as a whole. Thus, when the force-applying block 303 moves, it can drive the connecting block 304 to move. When the connecting block 304 moves, it can drive the positioning block 203 connected to it to move. Thus, when the positioning block 203 moves towards the blue film frame, it can perform clamping and positioning operations on the blue film frame. When the connecting block 304 drives the positioning block 203 connected to it to move, the synchronizing rod 2032 of the positioning block 203 can drive the synchronizing disk 202 to rotate through the synchronizing groove 2021. The synchronizing disk 202 rotates in the direction of the blue film frame. During rotation, the remaining synchronous slots 2021 can move synchronously with the positioning blocks 203 via their synchronous rods 2032. This allows the three positioning blocks 203 to move synchronously, enabling the positioning and clamping of the blue film frame. The top surfaces of the frame support plate 2031 and the support block 403 are on the same plane. The frame support plate 2031 also supports and holds the bottom of the blue film frame while positioning and clamping it, ensuring stable operation. The synchronous movement of the three positioning blocks 203 can change the effective inner diameter of the film frame positioning frame 201, thus adapting to the loading and positioning operations of blue film frames of different specifications. The clamping force of the carrier plate assembly 2 on the blue film frame has a limiting function, ensuring that the clamping force is controlled regardless of the size of the blue film frame being loaded. Both mechanisms maintain a constant clamping force, preventing damage or deformation of the blue film frame due to excessive clamping force, ensuring stable operation. When the positioning block 203 abuts against the side of the blue film frame, the positioning block 203 and connecting block 304 are unable to move further due to the resistance of the blue film frame. Subsequently, as the force-applying block 303 moves, it compresses the force-applying top spring 3032, thereby increasing the clamping and positioning force of the positioning block 203 on the blue film frame. At this time, the distance between the force-applying block 303 and the connecting block 304 changes. The distance sensor 3033 can monitor the distance between the force-applying block 303 and the connecting block 304 in real time. The distance between the force-applying block 303 and the connecting block 304 is the degree of compression of the force-applying top spring 3032, i.e., the clamping force of the positioning block 203 on the blue film frame.When the distance sensor 3033 detects that the distance between the force-applying block 303 and the connecting block 304 is at the set value, the drive motor 301 automatically shuts off the power and stops driving the force-applying block 303 to move. This allows the positioning block 203 to maintain its current clamping force to position the blue film frame. After the carrier assembly 2 has positioned the blue film frame, by controlling the extension of the electric push rod 401, the supporting block 403 can be flipped downwards to avoid interference. This ensures that the supporting block 403 does not interfere with the bottom space of the blue film frame, facilitating subsequent bottom-level positioning of the blue film frame. The lifting operation of the material on top of the membrane involves the extension of the electric push rod 401, which drives the lifting seat 402 to move downwards. As the lifting seat 402 moves, it causes the support block 403 to move downwards synchronously. Since the tilting rack 2011 is a fixed design and does not move with the lifting seat 402, the support block 403 tilts downwards under the action of the tilting gear 4031 and the tilting rack 2011. This ensures that the support block 403 does not interfere with the bottom space of the membrane frame, facilitating subsequent inspection and sorting operations.
