Description

Technical Field

[0001] The present invention relates to the technical field of display screen detection, in particular to an electric vehicle instrument display screen detection device. Background Art

[0002] After the display screen is produced, it is often necessary to conduct color difference testing on it. At present, in order to ensure the test results, the display screen is generally placed in a suitable position and then covered on all sides to prevent external light from penetrating before starting the test.

[0003] In the prior art, a Chinese patent with the announcement number CN211205708U discloses a display screen inspection device and equipment. Through a vacuum tube and a pneumatic suction cup, the screen surface is contacted and adsorbed. The first electric push rod is retracted to drive the vacuum generator upward, thereby driving the screen upward and moving backward under the action of the longitudinal slide. The first electric push rod and the vacuum generator work together to place unqualified screens in a storage box. When the number of screens in the storage box reaches a certain weight, the second electric push rod is activated to drive the vertical plate and the pin to rotate, and the second support plate is tilted under the action of the rotating shaft, so that the second support plate is docked with the limit plate. Further, the storage box slides down along the second support plate and falls on the limit plate, thereby facilitating the automatic collection of unqualified screens. This patent facilitates rapid inspection of screens, improves inspection efficiency, and automatically collects unqualified screens, thereby reducing the workload of workers, increasing collection efficiency, and avoiding the occurrence of wrong picking.

[0004] In the above technical solution, when collecting the display screens that fail the inspection, the display screens that fail the inspection are adsorbed by a vacuum suction cup and placed inside a storage box. However, there may be flexible cables or connectors under the display screens. If the pressure is transmitted to these components when the suction cup is pressed, poor contact or breakage may be caused. At the same time, the display screens inside the storage box will slide down and be collected after being stacked, causing the display screens inside the storage box to collide with each other, further exacerbating the secondary damage to the display screens, thereby reducing the effect of rejecting unqualified products when inspecting the display screens.

[0005] Based on this, an electric vehicle instrument display screen detection device is proposed. Summary of the Invention

[0013] Preferably, the surfaces of the multiple sliding rods are each sleeved with a spring 2, and the two ends of the multiple springs 2 are respectively fixedly connected to the inner wall of one side of the corresponding multiple sliding grooves and one side of the slider, and the inner wall of one side of the multiple sliding grooves is penetrated by a through hole, and the surfaces of the multiple sliding rods are respectively slidably connected to the inner walls of the corresponding multiple through holes.

[0014] Preferably, a plurality of upper contact plates are fixedly connected to the upper surface of the U-shaped plate, and a plurality of lower contact plates are fixedly connected to the lower surface of the rotating plate.

[0020] Compared with the prior art, the present invention has the following significant advantages:

[0021] First, when unqualified products are detected, the present invention lowers the air cylinder, driving the light-shielding cylinder to lower. The lowering of the light-shielding cylinder can simultaneously squeeze the slide plate 1 and the slide plate 2. The slide plate 1 and the slide plate 2 will follow the lowering under the action of the spring 1 until the bottom of the slide plate 1 and the slide plate 2 fall to the upper surface of the conveyor belt, thereby completing the rejection work. Unqualified products are rejected in a way that does not contact the display screen body, which can avoid the problem of secondary damage to the display screen body due to pressure during rejection.

[0022] Secondly, the present invention continues to descend through the cylinder, and the air pressure inside the circular groove is connected. At this time, the cylinder will drive the telescopic cylinder to descend during the process of continuing to descend. When the telescopic cylinder descends, it will synchronously drive the two T-shaped rods, and the two T-shaped rods will synchronously drive the rotating seat and the ball bearing to descend synchronously. When descending, they will squeeze the trapezoidal plates provided on the slide plate one and the slide plate two, thereby driving the slide plate one and the slide plate two to move in opposite directions, so that the display screen body can slide onto the conveyor belt. The display screen body is unloaded by the slide plate one and the slide plate two, which can reduce the possibility of collision of the display screen body during unloading. At the same time, the bottom of the slide plate one and the slide plate two is in contact with the conveyor belt for unloading, which can avoid the uneven force on the display screen body on the slide plate one and the slide plate two, resulting in different friction. When the slide plate one and the slide plate two are opened, the possibility of the display screen body tilting and falling can be improved, thereby improving the protection effect of the display screen body, and avoiding secondary damage to the unqualified display screen body when it is rejected.

[0023] Thirdly, after the unqualified products are unloaded, the rectangular cavity provided on the output end of the cylinder and the movable teeth provided therein come into contact with the gear. Under the action of the coil spring shaft, the movable teeth will not drive the rotation of the gear when the rectangular cavity moves downward. When unloading is completed and reset, the cylinder drives the telescopic cylinder to rise. At this time, the rectangular cavity drives the movable teeth to rise, and then drives the gear to rotate. The rotation of the gear can drive the conveyor belt. The transmission of the conveyor belt can transport the display screen body on the conveyor belt after unloading. Since the vertical rod provided under the trapezoidal plate can contact with the ball bearing, the slide plate one and the slide plate two are continuously limited after opening, which can provide motion compensation for the conveyor belt to transport the display screen body out, avoid accumulation and extrusion when unloading the unqualified display screen body again, and cause secondary damage to the display screen body, thereby further improving the protection effect.

[0037] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] The present invention provides an electric vehicle instrument display screen detection device through improvement. The technical solution of the present invention is:

[0039] like Figure 1-10 As shown, an electric vehicle instrument display screen detection device includes a base 1, a bottom plate 2 is fixedly connected to one side of the base 1, a top plate 4 is provided above the base 1, and further includes:

[0040] Rejection component, the rejection component includes a rejection blanking unit and a blanking protection unit;

[0041] The rejection and blanking unit includes a light-shielding cylinder 11. The light-shielding cylinder 11 can avoid the influence of ambient light on the detection when detecting the display screen body 35, which can improve the accuracy of the detection. An optical detector 15 is provided inside the light-shielding cylinder 11. The optical detector 15 is a prior art and can use a colorimeter for detection. It can quickly detect the color temperature and brightness of the display screen. A circular groove 16 is provided on the upper surface of the light-shielding cylinder 11. The inner wall of the circular groove 16 is slidably connected to the telescopic cylinder 7. The lower surface of the telescopic cylinder 7 is fixedly connected to the adapter ring 18. The surface of the adapter ring 18 is aligned with the inner wall of the circular groove 16. The wall is adapted for sliding connection, and the surface of the adaptor ring 18 can be made of flexible rubber material to improve the airtightness with the inner wall of the circular groove 16, thereby improving the sliding effect of the telescopic cylinder 7 in the circular groove 16. The lower surface of the adaptor ring 18 is fixedly connected with multiple springs 17, and the bottom ends of the multiple springs 17 are respectively fixedly connected to the inner bottom wall of the circular groove 16. There are four springs 17, and the annular array is distributed on the inner bottom wall of the circular groove 16, which can realize the reset and flexible support of the telescopic cylinder 7. The upper surface of the top plate 4 is fixedly installed with a cylinder 6, and the output end of the cylinder 6 is fixedly connected to the upper surface of the telescopic cylinder 7;

[0042] The material removal protection unit includes a rotating plate 5, and a plurality of material removal grooves 26 are provided on the upper surface of the rotating plate 5. The material removal grooves 26 are rectangular in design and are adapted to the sizes of the slide plates 1 31 and the slide plates 2 32 when closed. The inner walls of the plurality of material removal grooves 26 are slidably connected with the slide plates 1 31 and the slide plates 2 32. When the slide plates 1 31 and the slide plates 2 32 are lowered to remove the display screen body 35, the inner walls of the material removal grooves 26 can be used to initially limit the position of the display screen body 35. The upper surfaces of the slide plates 1 31 and the slide plates 2 32 are fixedly connected with two vertical rods 33, and the tops of the plurality of vertical rods 33 are fixedly connected with trapezoidal plates 34. By setting the two vertical rods 33, the trapezoidal plates 34 can be driven by the ball bearings 14 to squeeze the trapezoidal plates 34. When slide 1 31 and slide 2 32 are opened, the vertical rod 33 continuously contacts the ball 14. The distance between the vertical rod 33 can realize that the movable teeth 43 drives the gear 45 to rotate to convey the rejected products, thereby avoiding the interference of the conveyance of unqualified products with the closing of slide 1 31 and slide 2 32 during resetting. The surface of the telescopic cylinder 7 is fixedly connected to two T-shaped rods 12, and both ends of the two T-shaped rods 12 are fixedly connected to the rotating seat 13. The inner walls of multiple rotating seats 13 are movably connected to the balls 14. The balls 14 are movably installed inside the rotating seat 13, which can realize the rotation of the balls 14, thereby reducing the friction when squeezing the trapezoidal plate 34.

[0043] like Figure 7 and Figure 8As shown, the upper surface of the rotating plate 5 is fixedly connected to a plurality of U-shaped plates 28, the inner walls of the plurality of U-shaped plates 28 are fixedly connected to fixed blocks 30, the lower surfaces of the plurality of fixed blocks 30 are fixedly connected to spring three 41, and the upper surfaces of the slide plate 1 31 and the slide plate 2 32 are jointly provided with a display screen body 35. The setting of the spring three 41 can realize a flexible connection between the slide plate 1 31 and the slide plate 2 32 and the U-shaped plate 28, thereby realizing the rejection work.

[0044] Two sliding grooves 36 are provided on the upper surfaces of slide plate 1 31 and slide plate 2 32. The inner walls of one side of the multiple sliding grooves 36 are fixedly connected with sliding rods 37. The surfaces of the multiple sliding rods 37 are slidably connected with sliders 38. The surfaces of the multiple sliders 38 are respectively slidably connected to the inner walls of the corresponding multiple sliding grooves 36. The upper surfaces of the multiple sliders 38 are respectively fixedly connected to the bottom ends of the corresponding multiple springs 3 41.

[0045] The surfaces of the multiple slide bars 37 are all sleeved with springs 2 39, and the two ends of the multiple springs 2 39 are respectively fixedly connected to the inner wall of one side of the corresponding multiple slide grooves 36 and one side of the slider 38. The inner wall of one side of the multiple slide grooves 36 is penetrated by through holes 40, and the surfaces of the multiple slide bars 37 are respectively slidably connected to the inner walls of the corresponding multiple through holes 40. Through the set slide grooves 36, sliders 38, springs 2 39, slide bars 37 and through holes 40, it can be achieved that when slide plates 1 31 and slide plates 2 32 are lowered to fit the surface of the conveyor belt 10 after rejecting unqualified products, the sliding of slide plates 1 31 and slide plates 2 32 can be achieved without generating motion interference between springs 1 17, and through the action of springs 2 39 and slide bars 37, the reset effect of slide plates 1 31 and slide plates 2 32 can be achieved, and the setting of the through holes 40 can achieve avoidance of the slide bars 37.

[0046] like Figure 5 and Figure 7 As shown, the upper surface of the U-shaped plate 28 is fixedly connected with a plurality of upper contact plates 29, and the lower surface of the rotating plate 5 is fixedly connected with a plurality of lower contact plates 27. The setting of the lower contact plates 27 can make the protrusions 22 slide inside the conical cylinder 19 when rejecting unqualified products, thereby connecting the air path and realizing the sliding of the telescopic cylinder 7 inside the circular groove 16, thereby realizing the unloading after rejection. The setting of the upper contact plates 29 can realize the complete reset of the telescopic cylinder 7 after the cylinder 6 is reset. After resetting, the lower surface of the light-shielding cylinder 11 is higher than the upper contact plates 29, avoiding motion interference when the rotating plate 5 rotates. The interference area of the upper contact plate 29 adopts a triangular interference, which can realize the interference effect of the right-angle ball rod 23 when it is raised or lowered.

[0047] Two conical cylinders 19 are fixedly connected to the surface of the circular groove 16, and the inner walls of the two conical cylinders 19 are fixedly connected to a fixing frame 20. A sliding hole is opened on one side of the two fixing frames 20, and the inner walls of the two sliding holes are slidably connected to spring rods 21. One end of the two spring rods 21 is fixedly connected to a protrusion 22, and one side of the two protrusions 22 is fixedly connected to a right-angle ball rod 23. Through the setting of the conical cylinder 19, the air path can be connected and closed when the protrusion 22 moves, thereby controlling the air pressure inside the circular groove 16 and realizing the telescopic control of the telescopic cylinder 7.

[0048] like Figure 1 and Figure 5 As shown, a motor 24 is fixedly mounted on the lower surface of the base plate 2, and a rotating shaft 25 is rotatably connected to the upper surface of the base plate 2. The bottom end of the rotating shaft 25 is fixedly connected to the output end of the motor 24, and the top end of the rotating shaft 25 is fixedly connected to the lower surface of the rotating plate 5.

[0049] Support rods 3 are fixedly connected to both sides of the base 1, and the top ends of the two support rods 3 are fixedly connected to the lower surface of the top plate 4 respectively. The surface of one of the support rods 3 is slidably connected to a connecting rod 8, and the bottom end of the connecting rod 8 is fixedly connected to a rectangular cavity 9, and the top end of the connecting rod 8 is fixedly connected to the output end surface of the cylinder 6.

[0050] like Figure 9 and Figure 10 As shown, a plurality of coil spring shafts 42 are fixedly mounted on the inner wall of the rectangular cavity 9. The coil spring shafts 42 are prior art and are mainly used for storing or transmitting torque. They are often used in mechanical devices that require elastic reset or energy storage. Movable teeth 43 are fixedly mounted on the surface of the plurality of coil spring shafts 42, and the bottom of the movable teeth 43 is arranged in an arc shape.

[0051] The inner wall of the base 1 is rotatably connected to a transmission roller 44 , and the surfaces of the two transmission rollers 44 are covered with the same conveyor belt 10 . One end of one of the transmission rollers 44 passes through one side of the base 1 and is fixedly connected to a gear 45 .

[0052] The specific working method is as follows: when in use, the display screen body 35 to be inspected is first placed above the slide plate 1 31 and the slide plate 2 32, then the motor 24 is started, and the rotating plate 5 is driven by the motor 24 to rotate, so that the display screen to be inspected can be transferred to the bottom of the light shielding tube 11. The motor 24 stops rotating. At this time, the cylinder 6 drives the telescopic tube 7 and the light shielding tube 11 to descend synchronously. When the light shielding tube 11 descends to the point where the bottom surface is in contact with the upper surface of the slide plate 1 31 and the slide plate 2 32, the optical detector 15 inside the light shielding tube 11 begins to detect;

[0053] When a defective product with light leakage is detected on the screen, the cylinder 6 continues to descend. At this time, the light-shielding cylinder 11 will squeeze the slide plate 1 31 and the slide plate 2 32 at the same time. When the slide plates 1 31 and 32 fall to the bottom and fit the upper surface of the conveyor belt 10, the right-angled ball rod 23 provided on the light-shielding cylinder 11 will conflict with the lower contact plate 27 provided below the rotating plate 5, so that the right-angled ball rod 23 can drive the protrusion 22 to slide toward the inside of the conical cylinder 19, leaving space between the protrusion 22 and the conical cylinder 19. At this time, the cylinder 6 continues to descend, and the air pressure inside the circular groove 16 is connected. At this time, the cylinder 6 continues to descend. The telescopic cylinder 7 will be driven to descend. When the telescopic cylinder 7 descends, it will synchronously drive the two T-shaped rods 12. The two T-shaped rods 12 will synchronously drive the rotating seat 13 and the ball bearing 14 to descend. When descending, they will squeeze the trapezoidal plates 34 provided on the slide plate 1 31 and the slide plate 2 32, thereby driving the slide plate 1 31 and the slide plate 2 32 to move in opposite directions, so that the display screen body 35 can be slid onto the conveyor belt 10. The display screen body 35 is unloaded by descending the slide plate 1 31 and the slide plate 2 32, which can improve the protection effect of the display screen body 35 and avoid secondary damage to the display screen body 35 when rejecting unqualified display screen bodies 35.

[0054] After the unqualified product is unloaded, the rectangular cavity 9 provided on the output end of the cylinder 6 and the movable teeth 43 provided therein come into contact with the gear 45. Under the action of the coil spring shaft 42, the movable teeth 43 will not drive the rotation of the gear 45 when the rectangular cavity 9 moves downward. When the unloading is completed and reset, the cylinder 6 drives the telescopic cylinder 7 to rise. At this time, the rectangular cavity 9 drives the movable teeth 43 to rise, thereby driving the gear 45 to rotate. The rotation of the gear 45 can drive the conveyor belt 10. The transmission of the conveyor belt 10 can transport the display screen body 35 on the conveyor belt 10 after unloading. Since the vertical rod 33 provided under the trapezoidal plate 34 can contact the ball 14, the slide plate 1 31 and the slide plate 2 32 are continuously limited after opening, so that the conveyor belt 10 can transport the display screen body 35 out, provide motion compensation, avoid accumulation and extrusion when unqualified display screen body 35 is unloaded again, and cause secondary damage to the display screen body 35, further improving the protection effect;

[0055] During resetting, after the right-angle ball rod 23 disengages from the lower contact plate 27, the air pressure is blocked, thereby preventing the telescopic cylinder 7 from sliding inside the circular groove 16, until the cylinder 6 drives the telescopic cylinder 7 to reset to the right-angle ball rod 23 and contacts the upper contact plate 29 again. At this time, the air pressure is connected again, which can ensure that the telescopic cylinder 7 is completely reset, providing a guarantee for the next unloading. After the reset is completed, the motor 24 drives the rotating plate 5 to rotate again, which can realize continuous detection and continuous unloading of unqualified products, thereby improving detection efficiency.

[0056] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
