Description

TECHNICAL FIELD

[0001] The utility model relates to the field of defect detection, especially to a carrying device integrated with defect detection function. BACKGROUND

[0002] In ceramic SMT (Surface Mount Technology) production, luminescence detection is an important means to ensure that ceramic light source products function normally, quality is qualified, and performance is consistent. Luminescence detection not only can timely find unqualified products and reduce production loss, but also can improve production efficiency and ensure that products can meet industry standards and customer requirements, thereby obtaining better competitiveness in the market. With the development of automation and intelligent technology, the role of luminescence detection in ceramic SMT production is becoming increasingly important.

[0003] The existing luminescence detection method for ceramic SMT includes manual visual detection and machine visual detection. Manual visual detection relies on the operator to observe the luminescence of the ceramic light source through the eyes to judge whether it meets the specification requirements. Usually, the worker manually places the ceramic light source in the test fixture or uses a handheld stylus to press the product test point during the detection process, and then judges whether it is qualified by observing the lighting condition (such as brightness, luminescence color, etc.) of the LED chip. The advantage of manual detection is that it can be applied to ceramic light sources of different sizes and types, but due to the dependence on eye observation, it is easily affected by factors such as fatigue, environmental light, and vision difference, resulting in missed detection or misjudgment. The existing machine visual detection usually adopts a structure in which a carrying and positioning camera and a detection camera are used separately. The carrying and positioning camera is responsible for accurately capturing the position, posture, and direction of the ceramic light source through image recognition and positioning algorithm. This camera usually works with a robot system to help the robot complete accurate carrying and placement of the product. The defect detection camera is responsible for defect detection of the ceramic light source, mainly checking the appearance of the product, whether the light source is normally lit, whether there are defects on the surface, etc. This part usually relies on high-resolution cameras and image processing algorithms to identify and analyze images through a vision system to judge whether the product is qualified. This machine visual detection structure separates the detection equipment from the carrying system, can replace different detection equipment as needed, makes the system more flexible, and the independent detection camera can focus on the detection task to improve the detection precision and accuracy. However, since carrying and detection are completed by different devices, the whole system needs a more complex coordination mechanism, including the cooperation between the mechanical arm, the robot, and multiple cameras, which increases the complexity of the system, and since multiple cameras and devices are needed to complete different tasks, this system is usually large in size and occupies more space.

[0077] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the invention.

[0078] like Figures 1-3As shown, the utility model provides a kind of integrated defect detection function's handling device, fixed on ceramic light source test table 5, comprising: joint module 1, including first sub joint 11, second sub joint 12 and connecting shaft 13, one end of connecting shaft 13 is connected first sub joint 11, the other end is connected second sub joint 12, first sub joint 11 and second sub joint 12 can connecting shaft 13 as rotating center carry out the rotation movement in plane;Lifting module 2, including lifting shaft 21, lifting shaft 21 is arranged on first sub joint 11, lifting shaft 21 can be lifted relative to first sub joint 11 movement;Clamping module 3, clamping module 3 is fixed on the other end of lifting module 2;Clamping module 3 includes camera assembly 31, adapter assembly 32 and jaw assembly 33;One end of adapter assembly 32 is fixed on the other end of lifting module 2, and the other end is connected with camera assembly 31 and jaw assembly 33 respectively;Base 4, one end of base 4 is fixedly connected with second sub joint 12, and the other end is fixed on ceramic light source test table 5.

[0079] Preferably, fixed sheet metal can be provided on the outer wall of the joint module 1, to fix the required wire and / or air pipe and other lines on clamping module 3. Preferably, the fixed sheet metal is fixed on the outer wall of the joint module 1 by screws.

[0080] Preferably, the lifting shaft 21 is hollow inside and provided with flange seats at both ends, respectively, and an open rubber ring is embedded on each flange seat, for avoiding excessive friction between the wire and / or air pipe and other lines and the flange seat, which can cause line wear.

[0081] Preferably, the base 4 includes electromagnetic valve 41, fixed plate 42 and support column 43, the support column 43 connects two fixed plates 42, the lower fixed plate 42 is installed on the equipment table top, and the upper fixed plate 42 is used for fixing the integrated defect detection function's handling device. The electromagnetic valve 41 is installed on the side surface of the support column 43, for providing air source for the finger air cylinder 331 of clamping module 3.

[0082] When the ceramic light source is detected and transported by the integrated defect detection function of the conveying device, the camera assembly 31 collects and identifies information such as the position, shape and test point position of the ceramic light source, and then the gripper assembly 33 precisely grips the ceramic light source. After the gripper assembly 33 grips the ceramic light source, the lifting shaft 21 lifts the gripper assembly 33, and the first sub-joint 11 and the second sub-joint 12 move relative to the connecting shaft 13 to realize the movement of the gripper assembly 33 in the plane. After moving to the appropriate position, the lifting shaft 21 is lowered to the preset height, and the gripper assembly 33 is released to release the ceramic light source to the appropriate position. Moreover, during the gripping process and when the ceramic light source is lit, the camera assembly 31 collects images of the appearance and lit state of the ceramic light source, thereby detecting and judging the appearance and luminous brightness of the ceramic light source.

[0083] In an embodiment of the first aspect of the present application, the first sub-joint 11 and the second sub-joint 12 can move up and down along the axial direction of the connecting shaft 13.

[0084] Preferably, the first sub-joint 11 and / or the second sub-joint 12 can reciprocate along the axial direction of the connecting shaft 13, that is, the first sub-joint 11 and / or the second sub-joint 12 can move up and down, which provides more degrees of freedom for the operation of the device, enabling it to perform more complex task scenarios, such as large changes in the height of workpieces on the production line, test platforms or operation table surfaces with variable heights, or the need to span the height difference between different workstations. The joint module 1 equipped with the lifting function can adapt to more types of production environments and work requirements, thereby improving the movement flexibility of the joint module 1. Moreover, if the height is adjusted only by relying on the lifting module 2, it may have higher requirements for the structural strength, stroke range and control accuracy, leading to design complexity. Through the lifting function of the first and second sub-joints 12, part of the height adjustment demand can be shared, reducing the design complexity and operating load of the lifting module 2.

[0085] As shown in Figure 7 In an embodiment of the first aspect of the present application, the camera assembly 31 includes a camera body 311 and a plurality of auxiliary light sources 312. Preferably, the auxiliary light source 312 includes a protective rod 312a and a light emitting unit 312b. The protective rod 312a is made of aluminum, which is beneficial for rapid heat dissipation. The protective rod 312a has a through hole inside for passing the power line of the light emitting unit 312b. The lower end surface of the protective rod 312a is provided with a stepped counterbore for pasting the light emitting unit 312b, so that the light emitting unit 312b does not protrude from the lower end surface, thereby protecting the light emitting unit 312b. The lower end surface of the protective rod 312a is also provided with a chamfer, which is beneficial for light dispersion. The upper end surface of the protective rod 312a is provided with a limiting step, thereby ensuring the positional consistency after each disassembly and assembly.

[0086] It should be understood that when image acquisition needs to be performed in the unpowered state of the ceramic light source, since the ceramic light source itself does not emit light, the detection system needs to provide uniform illumination through the external auxiliary light source 312 to clearly capture the surface details of the ceramic light source, such as defects, scratches, cracks, or other appearance problems. Moreover, in some cases, even if the ceramic light source is powered to emit light, the light emission brightness can be uneven, or the brightness of certain areas is insufficient, which can affect the detection effect, and the auxiliary light source 312 can supplement the illumination to optimize the image quality. When in the powered state of the ceramic light source, since the lighting conditions in the factory environment can be complex and unstable (such as mixed light sources of natural light, fluorescent light, LED light, etc.). The auxiliary light source 312 can provide consistent and controllable lighting conditions to avoid unstable image quality due to changes in environmental light. Moreover, the auxiliary light source 312 can adjust the light direction, intensity, or color to make the defects on the surface of the ceramic light source more prominent, thereby facilitating the identification of the image processing algorithm, such as in surface detection, appropriate light sources can enhance the contrast between different materials or surface features (such as the contrast between cracks and normal surfaces), improving the accuracy of defect detection.

[0087] In an embodiment of the first aspect of the application, the adapter assembly 32 comprises a first adapter seat 321 and a wire pressing block 322.

[0088] As shown in Figures 4-5 The first adapter seat 321 is provided with a first through hole 321a axially penetrating along the upper and lower end surfaces, and the first adapter seat 321 is fixed to the lifting shaft 21 through the first through hole 321a; the first adapter seat 321 is also provided with a second through hole 321 axially penetrating along the front and rear end surfaces, and a first rectangular slot 321c is opened at the rear end surface to accommodate the wire pressing block 322, and the wire pressing block 322 is provided with a fourth through hole 322a.

[0089] It should be understood that preferably, the fourth through hole 322a is opened at the edge position of the wire pressing block 322, and the fourth through hole 322a is a non-complete circular through hole with a partial notch, which is used to realize the functions of clamping, guiding or limiting the movement range of parts such as power lines, network cables 313. Specifically, the notch design can cooperate with some shaft parts with corresponding protrusions or shape features, and when the parts are inserted or clamped into the opening through rotation, the notch part can play the role of guiding, positioning and fixing, avoiding the free sliding or disengagement of the parts. Preferably, the shape of the notch can be designed to adapt to the corresponding shape of the part, so as to limit the part clamped in the notch and prevent it from rotating or exceeding the set angle range.

[0090] In an embodiment of the first aspect of the present application, the adapter assembly 32 further comprises a cable clamping block 323, which comprises two sub-clamping blocks 323, each of which is provided with a semicircular through hole. When the two sub-clamping blocks 323 are aligned, the through holes on the two sub-clamping blocks 323 just enclose a complete circular third through hole 323a. The cable clamping block 323 is fixed outside the second through hole 321.

[0091] It should be understood that the two sub-clamping blocks 323 form a complete circular third through hole 323a after being aligned, which can tightly wrap around the cable, pipe or similar objects. This structure can achieve firm clamping of the cable or tubular object, preventing it from loosening or slipping due to vibration, external force or other reasons during operation. Moreover, during the operation of the device, the cable may be subjected to tensile or moving stress, and the cable clamping block 323 can effectively absorb and disperse these forces, preventing the cable from falling off or damaging the connection site. In addition, the sub-clamping blocks 323 are designed as a separable modular structure, which facilitates disassembly, replacement or re-adjustment when needed, such as when the diameter of the cable needs to be changed, only the corresponding specification of the cable clamping block 323 needs to be replaced, without the need to change the overall device.

[0092] Preferably, the diameter of the semicircular through hole can be designed as needed, and multiple semicircular through holes with different diameters can be provided on one cable clamping block 323, thereby adapting to cables or tubular objects of different diameters.

[0093] Preferably, in addition to the first through hole 321a and the second through hole 321, the first adapter seat 321 is also provided with a light source wiring hole g, a cable clamping block mounting hole d, a wire pressing block mounting hole e and a second adapter seat mounting hole f. The light source wiring hole g is provided on the four top corners of the upper and lower end faces of the first adapter seat 321, and is a through hole penetrating from both sides, which is used to accommodate the power cord of the auxiliary light source 312. When the installation angle of the auxiliary light source 312 changes, it still does not affect the direction of the power cord.

[0094] Preferably, the upper half of the first adapter 321 is provided in a semi-split structure, that is, the upper half of the first adapter 321 is split along the diameter of the first through hole 321a, and the two split parts are cut by a certain width in a direction perpendicular to the split surface, so that the first through hole 321a after reassembling after cutting is shortened in the diameter perpendicular to the cutting surface. And, an adjusting hole h is opened on the two split parts, which passes through the two parts at the same time, and is fixed by screws or other methods that can achieve the same adjustable fixing effect, and the distance between the two split parts is controlled by the screwing in or out of the adjusting screw. When the lifting shaft 21 passes through the first through hole 321a, the fixing strength of the first adapter 321 and the lifting shaft 21 can be adjusted by adjusting the screw. It should be understood that the method of obtaining the structure of the split first adapter 321 and adjusting the fixing strength between the first adapter 321 and the lifting shaft 21 by adjusting the distance between the two split parts falls within the scope of the present application.

[0095] Preferably, threaded holes are provided around the second through hole 321, and the wire clamping block 323 is fixedly connected with the first adapter 321 through the threaded holes.

[0096] As shown in Figure 6 Preferably, the adapter assembly 32 further includes a second adapter 324, which extends the structure of the first adapter 321. The second adapter 324 is provided with a fifth through hole (not shown) for accommodating the camera body 311, and a second rectangular groove is provided on one side of the fifth through hole for positioning the mounting position of the camera body 311, avoiding the rotation of the camera body 311 to any angle, and ensuring the concentricity.

[0097] Preferably, a light source mounting hole B is provided on the second adapter 324. Two tooth holes i are provided on the side and penetrate the light source mounting hole B, and the tooth holes i are used for screwing in the top wire j.

[0098] A plurality of mounting holes are provided on the lower end surface of the first adapter 321 for connecting with the second adapter 324, that is, the adapter 201 and the connecting plate 207 are provided with a plurality of mounting angles for facilitating the on-site angle adjustment by the installation and debugging personnel.

[0099] In an embodiment of the first aspect of the present application, the camera assembly 31 includes a camera body 311 and a network cable 313. The network cable 313 passes through the lifting shaft 21 and the first through hole 321a of the first adapter 321 in sequence, and then passes out from the second through hole 321 of the first adapter 321 and the third through hole 323a of the wire clamping block 323, and then extends into the first rectangular groove 321c through the fourth through hole 322a of the wire pressing block 322.

[0100] It should be understood that, due to the net line 313 sequentially passing through the first through hole 321a of the lifting shaft 21, the second through hole 321 of the first adapter seat 321, the third through hole 323a of the clamping block 323 and the fourth through hole 322a of the pressing block 322, such a multi-point fixing design forms a segmented guiding structure, which limits the movement range of the net line 313 in a stable path, thereby effectively reducing the large swing of the net line 313 due to inertia during high-speed movement of the equipment, and reducing the risk of stretching, twisting or bending stress of the net line 313. In the conventional equipment, the net line 313 is usually frequently bent, stretched or twisted due to movement, which causes the internal conductor and the external insulating layer to age or break. Through the fixing and guiding design, the movement trajectory of the net line 313 is strictly limited within the designed range, which significantly reduces the influence of mechanical fatigue on the service life of the net line 313. Moreover, after reducing the twisting and swinging amplitude, the physical wear of the net line 313 is greatly reduced, thereby prolonging the service life of the net line 313, reducing the downtime maintenance time of the equipment, and improving the production efficiency.

[0101] In an embodiment of the first aspect of the present application, the clamping jaw assembly 33 comprises a finger air cylinder 331, two clamping jaw seats 332, two clamping jaw rods 333 and a plurality of contact rods 334. One end of the finger air cylinder 331 is connected to the other end of the adapter assembly 32, and the other end is fixed with two clamping jaw seats 332. Two clamping jaw rods 333 are fixed on each clamping jaw seat 332. A plurality of contact rods 334 are fixed on the end of each clamping jaw rod 333 away from the clamping jaw seat 332, and a silica gel tube 334a is sleeved on the contact rod 334.

[0102] It should be understood that the finger cylinder 331 is connected to the main body of the device through the adapter assembly 32, which is the interface part of the overall device and the jaw assembly 33, ensuring that the jaw assembly 33 can be flexibly installed and adapted to different working scenarios. The finger cylinder 331 is driven by compressed air to reciprocate the piston, thereby realizing the opening and closing movement of the two jaw seats 332, providing a reliable power source for the clamping function. The cylinder action is stable and responds quickly, suitable for high-frequency grabbing and releasing tasks. The jaw seat 332, as the core connecting component of the jaw assembly 33, is used to fix the jaw rod 333 and transmit the driving force of the finger cylinder 331. The two jaw seats 332 are designed symmetrically and can simultaneously drive the synchronous opening and closing of the two jaw rods 333, ensuring the symmetry and stability of the clamping action. The contact rod 334 is fixed to the end of the jaw rod 333 and is the part that directly contacts the workpiece, responsible for the actual grabbing and clamping operation. The design of multiple contact rods 334 can effectively disperse the grabbing force, avoiding damage to the workpiece caused by single-point force. It is especially suitable for fragile or surface precision workpieces (such as ceramic light sources).

[0103] Preferably, the length and shape of the jaw rod 333 can be customized according to the size or shape requirements of the workpiece to adapt to different types of workpiece grabbing tasks.

[0104] In an embodiment of the first aspect of the present application, a magnetic sensor 335 is provided on the shell of the finger cylinder 331.

[0105] It should be understood that the magnetic sensor 335 usually adopts technologies such as Hall element or magnetic reed switch to realize real-time monitoring of the cylinder action state by sensing the position of the magnet carried by the piston inside the finger cylinder 331. By continuously monitoring the position of the piston during clamping, it can be judged in real time whether the action of the jaw is normal, such as whether the clamping is in place or whether there are abnormalities (such as workpiece falling, insufficient clamping, etc.). The magnetic sensor 335 provides accurate feedback information of the jaw position, and the control system can adjust the cylinder action according to the feedback to ensure that the jaw always moves along the expected trajectory, which is especially suitable for tasks that require high-precision clamping (such as detection or handling of ceramic light sources).

[0106] In an embodiment of the first aspect of the present application, the jaw seat 332 is L-shaped, and a U-shaped groove 332a with the same size and position is provided on the upper end face of each jaw seat 332. When the jaw seat 332 is fixed to the cylinder, the U-shaped groove 332a can limit and align the two jaw seats 332.

[0107] In an embodiment of the first aspect of the application, the jaw seat 332 is provided with a plurality of equidistant sawteeth on the end face in contact with the jaw rod 333, and the jaw rod 333 is also provided with matching sawteeth at the corresponding position of the jaw seat 332, and the jaw seat 332 and the jaw rod 333 are fixed by the engagement of the sawteeth.

[0108] It should be understood that the design of the sawteeth engagement can realize tool-free installation, and in the assembly process, the jaw rod 333 and the sawteeth on the jaw seat 332 are only aligned and engaged to complete the fixation, greatly shortening the installation time of the jaw assembly 33. Moreover, the equidistant design of the sawteeth ensures the accurate alignment of the jaw rod 333 and the jaw seat 332 during assembly, avoiding misalignment or deviation, ensuring the overall assembly quality of the jaw assembly 33, and the matching fixation mode of the sawteeth can avoid installation errors caused by human factors, improving the stability of the equipment operation. In addition, the equidistant structure of the sawteeth allows the jaw rod 333 to be adjusted at a fixed angle during installation, for example, each sawtooth corresponds to a small jaw rotation angle. The refinement of this angle adjustment can meet the clamping needs of different workpieces. In actual application, if it is necessary to change the position or angle of the jaw rod 333, it only needs to adjust the position after loosening the engagement, without the need for additional tools, and the operation is convenient and fast.

[0109] As shown in Figure 8 The carrying device with the integrated defect detection function carries the ceramic light source to the lighting area 53 for lighting detection, and then carries the ceramic light source to the qualified area 51 or the unqualified area 52 according to the detection result, so as to realize efficient automatic production.
