Description

[0002] An image sensor is a device that converts optical images into electronic signals. It is widely used in digital cameras and other electro-optical devices. Image sensors need to undergo optical function testing before being shipped.

[0003] An image sensor is placed on a fixture with a circuit pattern. The fixture clamps and secures the sensor and is powered on. The sensor acquires the pattern's content and sends it to a computer for comparison with set values. Products that pass the inspection are sent to the next process for packaging. Products that fail the inspection are placed on the NG line.

[0004] The sensors are small and neatly arranged on trays, which are then stacked on top of each other. A worker removes the top tray from the stack and uses tweezers to place an image sensor from it into a fixture. After testing, the sensor is placed into another tray.

[0005] Besides placing the sensors into and removing them from the fixture, the sorting and stacking of the material trays are all done manually. This is labor-intensive, has low testing efficiency, and the repeated manual conveying and stacking of the material trays can easily cause the sensors inside the trays to spill and cause contamination.

[0056] The invention will now be further described with reference to the accompanying drawings.

[0057] like Figures 1 to 12 As shown, the image sensor testing device of the present invention includes a main frame D, a lighting fixture assembly H, and a test light source assembly B; the lighting fixture assembly H is placed below the test light source assembly B; the lighting fixture assembly H consists of a fixture translation module H1 and a sensor fixture H2 connected to the fixture translation module H1; the sensor fixture H2 is connected to a circuit.

[0058] The main frame D is equipped with a feeding line assembly A, a receiving assembly E, a translation module F, and an NG receiving assembly G; the feeding line assembly A, the lighting fixture assembly H, and the receiving assembly E are arranged sequentially along the movement direction of the translation module F; a sensor feeding robot C is installed on the translation module F;

[0059] The feeding line assembly A is equipped with a tray stacking module for stacking trays, a tray separating module for removing the top tray, and a tray transfer module 2 for transferring the top tray on the tray separating module to the position below the sensor feeding robot C and at the location of the tray stacking module.

[0060] The structure of the receiving component E is the same as that of the feeding line component A. The receiving component E consists of two feeding line components A; the NG receiving component G is a fixture mounted on a straight module for clamping the material tray (X);

[0061] The first step involves stacking the trays X filled with sensors onto the tray separating module using an external robotic arm. The tray separating module then separates the topmost tray X from this position.

[0062] The second step is that the material tray transfer module 2 transports the material tray X separated by the tray separation module to the area directly below the sensor-loading robot C;

[0063] In the third step, the translation module F, in conjunction with the sensor loading robot C, removes the sensor from the material tray X and places it into the sensor fixture H2; the fixture translation module H1 transports the sensor fixture H2 with the sensor to directly below the test light source assembly B; the test light source assembly B lights up and displays a pattern, showing the pattern to the image sensor inside the sensor fixture H2; the sensor fixture H2 connects to the circuit, transmitting the received image to the computer for judgment of whether the sensor is intact.

[0064] Fourthly, the fixture translation module H1 transports the sensor fixture H2, equipped with the sensor, to a position misaligned with the test light source assembly B.

[0065] The translation module F, in conjunction with the sensor loading robot C, removes the inspected sensors from the sensor fixture H2. Qualified products are transported by the sensor loading robot C to the tray of the receiving component E; unqualified products are placed into the tray of the NG receiving component G.

[0066] Fifth step: After all the sensors in the material tray X below the sensor loading robot C are removed, the material tray transfer module 2 transports the material tray X, which has just been filled with sensors, to the material tray stacking module, and stacks the empty material trays through the material tray stacking module.

[0067] In this structure, the image sensor can achieve automatic detection, and the separation and stacking of the trays can be completed by the tray stacking module, the tray separation module, and the tray transfer module 2 working together. This reduces the risk of sensor spillage caused by manual tray transfer, and also reduces labor intensity and improves detection efficiency.

[0068] In a preferred embodiment of the present invention, the feeding line assembly A further includes a tray dividing frame 5; the tray stacking module, the tray dividing module, and the tray transfer module 2 are all disposed inside the tray dividing frame 5; the tray transfer module 2 is disposed between the tray stacking module and the tray dividing module; the tray stacking module includes a stacking lifting module 1 and limiting stop assemblies 6 disposed on the left and right sides of the tray dividing frame 5; two first support bars 9 are connected to the stacking lifting module 1; the tray transfer module 2 can pass through the gap between the two first support bars 9;

[0069] The limiting stop assembly 6 includes a U-shaped stop seat 601 fixed to the upper surface of the tray frame 5 and a flip plate 602 rotatably connected inside the U-shaped stop seat 601; one end of the flip plate 602 extends above the inner hole of the tray frame 5; the stacking lifting module 1 is essentially no different from the existing lifting module, so it will not be described in detail; both the tray stacking module and the tray separating module are provided with guide limiting plates 10 for guiding the tray X when it is pushed up, making the stacking more accurate; the bottom of the guide limiting plate 10 is provided with a power The tray X can pass through the slot; without external pushing force, the bottom surface of the flip plate 601 abuts against the inner bottom wall of the U-shaped retainer 601, and one end of the flip plate 602 extends above the inner hole of the tray frame 5; the tray transfer module 2 transports the empty tray X to the two first support bars 9 connected to the stacking lifting module 1; after the tray transfer module 2 releases its grip on the empty tray X, the stacking lifting module 1 drives the first support bars 9 to move upward, and the first support bars 9 transfer the tray. The tray X on module 2 is pushed upwards and stacked on the bottom of the tray X originally placed on the flip plate 602. When the tray X contacts the flip plate 602, the tray X pushes the flip plate 602 upwards until the tray X is completely higher than the top of the flip plate 602. Due to gravity, the flip plate 602 automatically flips and presses against the U-shaped stop 601. The stacking lifting module 1 drives the first support bar 9 to descend, and the tray X on the first support bar 9 is stuck on the top surface of the flip plate 602. In the stacking of material trays, the maximum flipping angle of the flipping plate 602 is not greater than 85 degrees to ensure that the center of the flipping plate 602 does not fall on the axis hinged to the U-shaped stop seat 601, and to ensure that the flipping plate 602 can automatically reset under the action of gravity; an electrostatic eliminator 7 is fixed on the tray frame 5; a limit guide component 8 is provided on the side wall of the tray frame 5; the rollers provided on the limit guide component 8 are used to assist the material tray transfer module 2 in limiting the material tray X.

[0070] In a preferred embodiment of the present invention, the flip plate 602 is provided with a limiting strip 602a; the internal cavity of the U-shaped stop 601 is provided with a limiting protrusion 601a; the limiting protrusion 601a is arranged in the direction of the swing of the limiting strip 602a; the function of the limiting protrusion 601a and the limiting strip 602a is to limit the flip angle of the flip plate 602, prevent the flip plate 602 from flipping more than 90 degrees, and ensure that the flip plate 602 can automatically reset every time it is pushed.

[0071] In a preferred embodiment of the present invention, the tray separating module includes a feeding lifting module 3 and a tray separating movable component 4; the tray separating movable component 4 includes multiple chuck units respectively disposed on both sides of the tray separating frame 5; each chuck unit includes a tray separating guide rail 405 fixed on the tray separating frame 5 and a tray separating clamping plate 403 slidably connected to the tray separating guide rail 405; the tray separating clamping plate 403 on the same side is fixed by a tray separating connecting rod 402; a tray separating drive cylinder 401 is fixed on the bottom plate of the tray separating frame 5; and tray separating connecting rods 404 are hinged to the tray separating connecting rods 402.

[0072] The piston rod ends of the disc drive cylinder 401 are all hinged to the disc connecting rod 404; the loading lifting module 3 is connected to the second support bar 11; the material tray transfer module 2 can pass through the gap between the two second support bars 11; the loading lifting module 3 is not fundamentally different from the existing lifting module, so it will not be described in detail; the material trays X are stacked on the two second support bars 11 of the loading lifting module 3; in the initial state, the disc clamping plate 403 retracts to a position that does not obstruct the material trays X from passing through the second support bars 11; after the bottom surface of the topmost material tray X on the second support bar 11 is just aligned with the disc clamping plate 403, the disc drive cylinder 401 drives the disc connecting rod 404 to move, so that the disc clamping plates 403 on both sides retract inwards simultaneously, and the disc clamping plates 403 on both sides respectively clamp into the bottom of the material tray X to support the material tray X; wait for the material tray transfer module 2 to grab it to the bottom of the sensor loading robot C.

[0073] In a preferred embodiment of the present invention, the tray transfer module 2 includes a clamping claw unit 204 and a clamping claw power unit capable of moving the clamping claw unit 204; the clamping claw unit 204 includes a tray support plate 204d, a rotating disk 204e rotatably connected to the tray support plate 204d, and a first cylinder 204a with one end connected to the tray support plate 204d; the first cylinder 204a is hinged at an eccentric position of the rotating disk 204e;

[0074] Both ends of the tray support plate 204d are hinged with claws 204c, and each end of the claws 204c is hinged with a connecting rod 204b. The ends of the connecting rods 204b are hinged to both sides of the rotating disk 204e. The first cylinder 204a starts and drives the rotating disk 204e to rotate. The rotating disk 204e drives the rotating disk 204e to rotate, so that the two connecting rods 204b move synchronously, clamping the two claws 204c by holding the front and rear ends of the tray X. Since the two connecting rods 204b are connected to the same rotating disk 204e, the swing angle of each claw 204c is consistent when clamping the tray X. This improves the consistency of the tray support plate 204d's positioning of the tray X each time, improves the positional accuracy of the image sensor below the sensor loading robot C, and makes the sensor loading to the sensor fixture H2 more accurate. The contact between the sensor and the circuit on the sensor fixture H2 is more accurate, reducing the risk of good products being reported as NG and improving the actual yield. The gripper power unit includes a translation motor 201 with one end fixed to the tray frame 5, a translation screw 202 rotatably connected to the tray frame 5, and a translation screw nut 203 threadedly connected to the translation screw 202. A long guide rail is fixed to the surface of the tray frame 5. A translation slider 205 that is slidably connected to the long guide rail is fixed to the translation screw nut 203. The other end of the translation motor 201 is fixedly connected to the translation screw 202. The tray support plate 204d is fixed to the translation screw nut 203. After the translation motor 201 is started, it drives the translation screw 202 to rotate, and pushes the translation slider 205 to slide on the long guide rail through the translation screw nut 203, thereby realizing the translation movement of the gripper unit 204.

[0075] In a preferred embodiment of the present invention, there are two tray transfer modules 2; one tray transfer module 2 is used for tray conveying between the tray stacking module and the sensor loading robot C; the other tray transfer module 2 is used for tray conveying between the tray splitting module and the sensor loading robot C; by having the two tray transfer modules 2 respectively responsible for different conveying ranges, the conveying time of tray X is reduced, the conveying efficiency of tray X is improved, the waiting time is reduced, and the conveying efficiency of tray X is improved.

[0076] In a preferred embodiment of the present invention, the test light source assembly B includes a gantry B1, a light source lifting module connected to the gantry B1, and a light source lifting plate B2 slidably connected to the gantry B1; multiple light source lifting cylinders B4 are connected to the light source lifting plate B2; each of the light source lifting cylinders B4 is equipped with a light source B5; the light source lifting module is connected to the light source lifting plate B2; when the light source B5 is lit, the imaging plate on the front surface of the light source B5 produces a bright image; the light source lifting module drives the light source lifting plate B2 to move, adjusting the reference height of the light source B5; the light source lifting cylinders B4 drive the light source B5 and the imaging plate down to a set height, so that the image sensor in the sensor fixture H2 below can acquire the best image.

[0077] In a preferred embodiment of the present invention, the light source lifting module includes a light source lifting motor B3, a belt B9, and two parallel lifting screws B6; the two lifting screws B6 are rotatably connected to both sides of the gantry frame B1; a synchronous pulley B8 is fixed on each of the two lifting screws B6; the belt B9 is tensioned between the two synchronous pulleys B8; one end of the light source lifting motor B3 is fixed to the gantry frame B1; the other end of the light source lifting motor B3 is fixed to one of the lifting screws B6; a lifting nut B7 is threaded onto each of the lifting screws B6; the lifting nut B7 is fixed to the light source lifting plate B2;

[0078] The light source lifting motor B3 starts and drives the lifting screw B6 to rotate. The synchronous pulley B8 and belt B9 make the lifting screw B6 rotate synchronously; this drives the light source lifting plate B2 to move up and down, ensuring that the lifting amount on both sides of the light source lifting plate B2 is consistent, and the imaging effect is more stable.

[0079] In a preferred embodiment of the present invention, the sensor loading robot C includes a camera vision inspection system C2 and multiple sensor loading nozzles C1. The camera vision inspection system C2 and the sensor loading nozzles C1 are essentially no different from existing technologies, and therefore will not be described in detail. A lifting structure is connected to each sensor loading nozzle C1 to drive its lifting movement. After the sensor is adsorbed and fixed by the sensor loading nozzle C1, it is transferred to the camera vision inspection system C2 for appearance inspection. The sensor loading nozzle C1 is used to adsorb and fix the sensor.

[0080] In using this invention, the first step involves stacking trays filled with sensors onto the tray-separating module using an external robotic arm. Once the bottom surface of the top tray on the second support bar is aligned with the tray-separating clamping plate, the tray-separating drive cylinder moves the tray-separating connecting rod, causing the tray-separating clamping plates on both sides to retract inwards synchronously and engage with the bottom of the tray to support it. The tray transfer module then picks it up and places it below the sensor loading robotic arm. The second step involves starting the first cylinder, which rotates the rotating disk. This rotation causes the two connecting rods to move synchronously, and the two claws pass through the front and rear ends of the tray. Clamping; After the translation motor starts, it drives the translation screw to rotate, which pushes the translation slider to slide on the long guide rail through the translation screw nut, conveying the material tray to directly below the sensor loading robot; In the third step, the translation module, in conjunction with the sensor loading robot, takes the sensor out of the material tray and puts it into the sensor fixture; The fixture translation module conveys the sensor fixture with the sensor to directly below the test light source assembly; The test light source assembly lights up and displays a pattern, and shows the pattern to the image sensor inside the sensor fixture; The sensor fixture connects to the circuit and transmits the received image to the computer to determine whether the sensor is intact;

[0081] The fourth step involves the fixture translation module transporting the sensor fixture with the sensor to a position misaligned with the test light source assembly.

[0082] The translation module, in conjunction with the sensor loading robot, removes the inspected sensors from the sensor fixture. Qualified products are transported to the receiving assembly's tray by the sensor loading robot; unqualified products are placed into the receiving assembly's tray.

[0083] Fifth step: After all the sensors in the tray below the sensor loading robot are removed, the tray transfer module transports the tray with the removed sensors to the tray stacking module, which then stacks the empty trays.

[0084] In this structure, the image sensor can achieve automatic detection, and the separation and stacking of the trays can be completed by the tray stacking module, the tray separation module, and the tray transfer module working together. This reduces the risk of sensor spillage caused by manual tray transfer, and also reduces labor intensity and improves detection efficiency.

[0085] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
