Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, specifically a camera device for detecting the concentricity of a flexible interface. Background Technology

[0002] Existing flexible interface concentricity testing equipment generally employs visual inspection. The platform holding the flexible interface is usually rigidly connected to the moving mechanism, with all weight directly acting on the slide rails and lead screws. Long-term operation can easily lead to bending and deformation of the threaded shafts and slide rails, affecting accuracy and lifespan. Furthermore, the camera can only photograph a single row of interfaces; when inspecting multiple rows, a moving joint must be installed on the camera to achieve multi-row inspection, resulting in low efficiency. Therefore, there is an urgent need for a flexible interface concentricity testing device with reasonable force distribution, a detachable platform, and integrated camera translation for continuous visual inspection of multiple rows of interfaces. This would solve the problems of inconvenient loading and unloading, unreasonable load-bearing capacity, and low inspection efficiency inherent in existing technologies. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a camera device for detecting the concentricity of a flexible interface, which can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: A camera device for detecting the concentricity of flexible interfaces, comprising a platform plate, brackets fixed on the top left and right sides of the platform plate, a side plate fixed on the upper side of the left bracket, slide rails fixed on the side plate and the right bracket, a slider slidably disposed on the slide rail, a locking block fixed on the top of the slider, and a crossbeam fixed between the locking blocks. The crossbeam is characterized in that a camera assembly is fixed on the front side of the crossbeam, a threaded rod assembly is disposed on the side plate to move the locking block and the crossbeam back and forth as a whole, a placement plate is disposed above the platform plate, multiple flexible interfaces are mounted on the placement plate, a feeding assembly is disposed at the bottom of the platform plate to drive the placement plate to move back and forth to achieve the feeding function, a left and right track is disposed on the top of the platform plate, a left and right protrusion is fixed in the track, a bottom block is fixed at the bottom of the placement plate, the bottom block is slidably connected to the protrusion, and the bottom block is limited by the track and slides back and forth.

[0005] In a further technical solution, a plurality of limiting discs are fixed on the top of the placement plate, and the limiting discs are used to engage the flexible interface.

[0006] A further technical solution includes a mounting bracket, on the bottom of which multiple camera modules are fixedly connected.

[0007] A further technical solution includes a threaded rod assembly comprising a motor mounting plate fixed to the upper side of the side plate, with one motor mounting plate at the front and one at the rear. A vertical plate is also fixed to the upper surface of the side plate. A lead screw is rotatably mounted between the vertical plate and the front motor mounting plate, the lead screw rotatably passing through the vertical plate. A lead screw motor is fixed to the rear side of the motor mounting plate, the output shaft of the lead screw motor rotatably passing through the motor mounting plate. The motor mounting plate is poweredly connected to the lead screw via a coupling. An internal threaded sleeve is fixedly mounted inside the retaining block, the lead screw passes through the internal threaded sleeve, and the lead screw and the internal threaded sleeve are threadedly connected.

[0008] A further technical solution includes a feeding assembly comprising a movable frame, wherein a plurality of plug-in blocks are fixedly disposed on the top of the movable frame, and a slot is disposed in the bottom block, wherein the plug-in blocks are inserted into the slots to engage with the bottom block, and a movable structure is disposed at the bottom of the platform plate to drive the plug-in blocks to slide back and forth between the protrusions.

[0009] A further technical solution includes a connecting plate fixed to the bottom of the moving frame, a fixed frame and an end plate fixed to the bottom of the platform plate, a sliding rod fixed between the fixed frame and the end plate, the sliding rod sliding through the connecting plate, a motor fixed on the fixed frame, a threaded shaft poweredly connected to one side of the motor, the threaded shaft rotatably connected to the end plate, the output shaft of the motor poweredly connected to the threaded shaft, and the threaded shaft threadedly connected to the connecting plate.

[0010] The beneficial effects of this utility model are as follows: First, compared with the prior art, the overall solution of this equipment has the advantage that personnel can move the placement plate and flexible interface onto the moving frame and plug-in block, and can also remove them from it, which is convenient for loading and unloading. The placement plate can be moved backward by the moving frame, and the camera module can visually inspect the rows of flexible interfaces. It can also visually inspect other rows of flexible interfaces as the crossbeam, connecting seat and mounting bracket move forward. After the inspection is completed, the placement plate can be moved forward by the moving frame, and personnel can take out the flexible interfaces that do not meet the specifications. Then the entire placement plate can be moved away, so that personnel can continuously send the placement plate and flexible interface into the equipment for inspection.

[0011] Second, by using the protrusion to abut against the base block, the protrusion supports the base block, the placement plate, and the flexible interface, avoiding the mobile frame from bearing too much weight. This allows the mobile frame and the plug-in block to only overcome the friction between the base block and the protrusion, resulting in better stress distribution and preventing the connecting plate and the mobile frame from bearing too much weight, which could cause the threaded shaft and the slide rod to bend.

Detailed Implementation

[0023] like Figures 1-9 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1The projection relationship is consistent in all directions (up, down, left, right, front, back). This utility model discloses a flexible interface concentricity detection camera device, including a platform plate 15. Supports 18 are fixed to the top left and right sides of the platform plate 15. A side plate 14 is fixed to the upper side of the left support 18. A slide rail 19 is fixed to the side plate 14 and the right support 18. A slider 21 is slidably mounted on the slide rail 19. A locking block 22 is fixed to the top of the slider 21. A crossbeam 35 is fixed between the locking blocks 22. A camera assembly is fixed to the front of the crossbeam 35. The side plate 14 is equipped with a mechanism to move the locking blocks 22 and the crossbeam 35 back and forth as a whole. The moving threaded rod assembly has a platform plate 15 with a placement plate 17 on top. The placement plate 17 is equipped with multiple flexible interfaces 16. The bottom of the platform plate 15 is equipped with a feeding assembly that moves the placement plate 17 back and forth to achieve the feeding function. The top of the platform plate 15 is also equipped with a left and right track 42. The left and right protrusions 43 are fixed in the track 42. The bottom of the placement plate 17 is fixed with a bottom block 41. When the placement plate 17 and the bottom block 41 are placed in the track 42, the bottom block 41 slides and engages on the protrusions 43, and the bottom block 41 is limited by the track 42 and slides back and forth.

[0024] Beneficially, the flexible interface 16 is made of rubber material and is formed by one-piece molding of rubber. The flexible interface is hollow and has flanges at the top and bottom for connecting other components. After the flanges are installed on its body, its concentricity determines whether there is a large internal stress in its structure after installation. Although the rubber structure has the ability to deform flexibly, when it is connected to other components, if the other components require a high degree of concentricity, the flexible interface 16 with poor concentricity will be twisted and deformed after connection and installation, resulting in a large internal stress and affecting the connection and use effect.

[0025] Advantageously, a plurality of limiting discs 71 are fixed on the top of the placement plate 17, and the limiting discs 71 are used to snap the flexible interface 16.

[0026] Advantageously, the camera assembly includes a mounting bracket 36, with multiple camera modules 37 fixedly connected to the bottom of the mounting bracket 36. The mounting bracket 36 has a cavity through which the camera body of the camera module 37 passes. Connecting seats 34 are fixed on the left and right sides of the mounting bracket 36 and are fixedly connected to the crossbeam 35. When the flexible interface 16 on the placement plate 17 is located below the camera module 37, the camera body in the camera module 37 is opposite to the flexible interface 16, enabling multiple camera modules 37 to perform simultaneous visual recognition of the row of flexible interfaces 16.

[0027] Advantageously, the camera module 37 has a camera body fixedly installed in the middle, and light panels are fixed on the left and right sides of the bottom of the camera module 37. The camera body needs to be connected to a PC in the external space and also needs to be connected to a power source to realize the function of real-time transmission of image data.

[0028] Advantageously, the threaded rod assembly includes a motor mounting plate 12 fixed to the upper side of the side plate 14, with one motor mounting plate 12 at the front and one at the rear. A vertical plate 13 is also fixed to the upper surface of the side plate 14. A lead screw 23 is rotatably mounted between the vertical plate 13 and the front motor mounting plate 12. The lead screw 23 rotatably passes through the vertical plate 13. A lead screw motor 11 is fixed to the rear side of the motor mounting plate 12. The output shaft of the lead screw motor 11 rotatably passes through the motor mounting plate 12. The motor mounting plate 12 is poweredly connected to the lead screw 23 through a coupling. The coupling is sleeved on the outer surface of the lead screw 23 and the output shaft of the lead screw motor 11 and is connected and fixed. An internal threaded sleeve 33 is fixedly mounted inside the locking block 22. The lead screw 23 passes through the internal threaded sleeve 33, and the lead screw 23 and the internal threaded sleeve 33 are threadedly connected.

[0029] Advantageously, the feeding assembly includes a movable frame 44, with multiple plug-in blocks 45 fixedly installed on the top of the movable frame 44, and a slot 61 provided in the bottom block 41. The plug-in blocks 45 are inserted into the slot 61, so that the plug-in blocks 45 are engaged with the bottom block 41. The bottom of the platform plate 15 is provided with a movable structure that drives the plug-in blocks 45 to slide back and forth between the protrusions 43.

[0030] Advantageously, the movable structure includes a connecting plate 54 fixed to the bottom of the movable frame 44, a fixed frame 52 and an end plate 57 fixed to the bottom of the platform plate 15, a slide rod 55 fixed between the fixed frame 52 and the end plate 57, the slide rod 55 slidingly passing through the connecting plate 54, a motor 51 fixed on the fixed frame 52, a threaded shaft 53 poweredly connected to one side of the motor 51, the threaded shaft 53 being rotatably connected to the end plate 57, the output shaft of the motor 51 being poweredly connected to the threaded shaft 53 through a coupling, the threaded shaft 53 passing through the connecting plate 54, and the threaded shaft 53 being threadedly connected to the connecting plate 54.

[0031] Advantageously, after the movable frame 44 moves forward, the front half of the movable frame 44 passes through the through slot 56, so that the plug block 45 on the upper side of the movable frame 44 can move the placement plate 17 to a more forward position.

[0032] In the initial state of the device, such as Figure 6 and 7 As shown, the placement plate 17 and the moving frame 44 are located in front of the platform plate 15. At this time, the placement plate 17, which is loaded with the flexible interface 16, has been connected to the top of the moving frame 44 through the cooperation of the bottom block 41 and the plug block 45. The flexible interface 16 can be placed on the top of the moving frame 44 and connected manually.

[0033] When the device is in operation, the motor 51 drives the threaded shaft 53 to rotate. The threaded shaft 53 is threadedly connected to the connecting plate 54, and the slide rod 55 is slidably connected to the connecting plate 54. After the threaded shaft 53 rotates, it can drive the connecting plate 54 and the moving frame 44 to move backward. A baffle 75 is fixed on the platform plate 15. A limit switch is set on the front side of the baffle 75. When the moving frame 44 drives the placement plate 17 to move backward, the placement plate 17 touches the limit switch on the front side of the baffle 75, causing the motor 51 to stop working. The specific control process also requires the setting of a controller. The controller is electrically connected to the motor 51, and the limit switch is electrically connected to the controller to transmit electronic signals.

[0034] At this time, the camera module 37 is directly opposite the flexible interface 16 in the first row on the top rear side of the placement plate 17. After the camera module 37 starts working, it begins to collect information. The camera of the camera module 37 takes pictures from bottom to top. When the concentricity of the flanges at the top and bottom of the flexible interface 16 is not high, double images will be formed. By judging whether there is a double image or the size of the double image area, it is determined whether the concentricity is poor. The images that do not meet the requirements are marked on the PC. Based on the feedback marking information, the personnel remove the flexible interface 16 that does not meet the requirements to improve the yield rate when leaving the factory.

[0035] When inspecting the flexible interfaces 16 of other rows, the lead screw motor 11 drives the lead screw 23 to rotate. After the lead screw 23 is threadedly connected to the internal threaded sleeve 33, the locking block 22 is slidably connected to the slide rail 19 through the slider 21. This causes the locking block 22 to move the crossbeam 35, the connecting seat 34, the mounting bracket 36, and the camera module 37 forward. The distance moved is exactly the center line distance between the front and rear flexible interfaces 16, so that the camera module 37 is located above the more forward flexible interface 16, so that the camera module 37 can inspect the flexible interfaces 16 of the front row in sequence.

[0036] After inspection, the lead screw motor 11 operates, indirectly resetting the mounting bracket 36 and camera module 37 to their rearward positions. Then, the motor 51 operates, driving the threaded shaft 53 to rotate, causing the connecting plate 54 and the moving frame 44 to move the placement plate 17 and flexible interface 16 forward to their initial front positions. Personnel then manually remove the defective products based on the defective product location information displayed on the PC screen. Finally, the conforming placement plate 17 is moved to the good product area.

[0037] Afterwards, the personnel place the other placement plates 17 and flexible interfaces 16 on the upper side of the mobile frame 44. When the bottom block 41 is placed on the protrusion 43, the protrusion 43 is supported by the bottom block 41, allowing the bottom block 41 to slide on the upper surface of the protrusion 43. The plug-in block 45 is engaged with the bottom block 41, reducing the load on the bottom block 41 and the placement plate 17 by the mobile frame 44 and the plug-in block 45, while providing more forward and backward driving force.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
