Description

Technical Field

[0001] This invention relates to the field of automated dispensing and visual inspection technology, and in particular to a dispensing inspection device for the bottom shell of electronic devices. Background Technology

[0002] In the manufacturing process of electronic products, smart terminals and wearable devices, the bottom shell usually needs to be coated with an adhesive in designated locations to achieve the purpose of sealing, waterproofing or structural fixation.

[0003] Chinese patent application CN202110036018.7 discloses an automatic dispensing machine, including a machine base. The machine base is equipped with a rotating disc, a feeding mechanism, a dispensing mechanism, a dispensing vision inspection mechanism, an insulating sheet bending and assembly mechanism, a riveting mechanism, a riveting vision inspection mechanism, and a dispensing mechanism. The rotating disc is rotatably connected to the center of the machine base. The feeding mechanism, dispensing mechanism, dispensing vision inspection mechanism, insulating sheet bending and assembly mechanism, riveting mechanism, riveting vision inspection mechanism, and dispensing mechanism are sequentially arranged beside the rotating disc along its rotation direction. This machine can simultaneously dispense adhesive into plastic shell products and bend insulating sheets, ensuring uniform dispensing and precise assembly of the insulating sheets, thus guaranteeing the quality of the plastic shell products.

[0004] Chinese patent application CN202110266803.1 discloses a multi-station automatic dispensing device, including a worktable, a turntable in the middle of the worktable, a cam divider below the turntable, the cam divider driving the turntable to rotate, and multiple fixture seats arranged in a concentric array on the upper surface of the turntable. A mobile phone case feeding mechanism and a bracket dispensing and assembly mechanism are respectively fixedly mounted on the worktable around the turntable and matched with the fixture seats. A bottom detection mechanism is provided on the worktable to the right of the bracket dispensing and assembly mechanism. The dispensing and mounting positions of the camera bracket are precisely positioned by the CCD camera of the dispensing mechanism and the second CCD camera of the bottom detection mechanism, and the bracket position is finely adjusted by a fine-tuning device and a three-axis module.

[0005] The existing automatic dispensing equipment typically employs a rotary multi-station structure, using fixtures to sequentially transport workpieces to the dispensing and inspection stations, thereby achieving automated production.

[0006] However, the fixtures in the aforementioned prior art mostly adopt rigid limiting structures, which have limited adaptability to the dimensional tolerances, warping deformation and placement deviations of the bottom shell. This can easily cause the dispensing trajectory to deviate from the outline of the bottom shell, affecting the consistency of the dispensing line. At the same time, differences in the thickness of the bottom shell or local unevenness can also lead to inconsistent dispensing heights, thereby affecting the accuracy of dispensing quality inspection.

[0007] Therefore, this invention discloses an adhesive dispensing inspection device for the bottom shell of electronic devices to solve the above problems. Summary of the Invention

[0008] Based on this, it is necessary to provide an electronic device bottom shell dispensing and testing device to address the above-mentioned technical problems. The device uses a turntable to rotate intermittently, causing the bottom shell inside the fixture assembly to pass through the dispensing assembly and the testing assembly in sequence, thereby realizing the dispensing and dispensing testing of the bottom shell.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Please refer to Figures 1-7This invention provides an electronic device bottom shell dispensing and testing device, comprising a body 1 with a worktable 11, a turntable 12 on the worktable 11, and a driving device 13 on the lower side of the turntable 12. The turntable 12 rotates intermittently under the action of the driving device 13. The turntable 12 is provided with several fixture components 2. In this embodiment, there are four fixture components 2 arranged circumferentially. When the turntable 12 is stationary, the four fixture components 2 are used sequentially for the bottom shell 9 loading station, dispensing station, testing station, and unloading station, thereby realizing the loading, dispensing, testing, and unloading operations of the bottom shell 9 at the same time. Each fixture component 2 includes a fixture body with a placement groove 21. The upper part of the placement groove 21 is a funnel shape with a larger upper part and a smaller lower part is a rectangular groove, an elliptical groove, or a groove of other shapes. An adaptive positioning component is provided, located at the lower part of the placement slot 21. The adaptive positioning component can adaptively adjust the position and orientation of the bottom shell 9 after it is placed. A dispensing component 3 and a detection component 4 are arranged sequentially on the worktable 11 along the rotation direction of the turntable 12. The dispensing component 3 is used to dispense glue onto the bottom shell 9, and the detection component 4 is used to detect the glue quality of the bottom shell 9 after dispensing. The detection component 4 includes a vision detection unit 41, which is used to detect the position, width and continuity of the glue line. The turntable 12 is in a stopped state during the dispensing and dispensing detection process. A stand 14 is fixed to the rear side of the worktable 11, and a display screen 15 and an operation panel 16 are fixed on the stand 14. With the built-in control system, the operation and real-time monitoring of the entire bottom shell 9 dispensing detection equipment can be realized.

[0028] like Figures 1-3As shown, furthermore, a feeding mechanism 5 and a discharging mechanism 6 are fixed on the workbench 11. The feeding mechanism 5 and the discharging mechanism 6 adopt the same structure. Specifically, taking the feeding mechanism 5 as an example, it includes a linear guide rail module 51. A lifting structure 52 is slidably provided on the linear guide rail module 51. An adsorption structure 53 is provided on the lifting structure 52. The adsorption structure 53 has two negative pressure heads for adsorbing and fixing the bottom shell 9. Under the drive of the lifting structure 52 and the linear guide rail module 51, the bottom shell 9 is fed or unloaded. A material conveying mechanism 7 and a material discharging mechanism 8 are arranged side by side on one side of the machine body 1, both for conveying the bottom shell 9. A limiting plate 71 is provided on the material conveying mechanism 7 for limiting the bottom shell 9. The limiting plate 71 is provided with The material inlet 72 and the limiting plate 71 allow the bottom shell 9 to be conveyed along a certain path until it reaches the material inlet 72. A vision inspection mechanism 73 is provided above the material inlet 72. The vision inspection mechanism 73 is used to visually inspect the bottom shell 9 to determine whether the bottom shell 9 has been conveyed to the correct position. After the vision inspection mechanism detects the bottom shell 9 from the material inlet 72, the lifting structure 52 drives the adsorption structure 53 to descend and adsorb and fix the bottom shell 9. Driven by the linear guide module 51, the bottom shell 9 is sent to the fixture assembly 2 of the loading station of the turntable 12. The unloading mechanism 6 is located after the detection assembly 4. After the detection assembly 4 inspects the quality of the glued bottom shell 9, the unloading mechanism 6 takes out the bottom shell 9 from the fixture assembly 2 and places it on the discharge conveying mechanism 8 to output the bottom shell 9.

[0029] like Figure 6 , Figure 7As shown, the adaptive positioning component further includes an elastic limiting structure 22, which includes an elastic limiting member and a positioning reference surface 23 that cooperates with it. The elastic limiting member is in a restricted elastic deformation state after the bottom shell 9 is placed, and the elastic limiting structure 22 is disposed on at least one or more sides of the bottom shell 9 for positioning the bottom shell 9 in the horizontal direction. In this embodiment, the elastic limiting structure 22 is disposed on one side of the long side of the placement groove 21, while the positioning reference surface 23 is disposed on the opposite side of the elastic limiting structure 22. Specifically, the elastic limiting member is a sliding telescopic column with a built-in compression spring, and a pin head is provided at the end of the telescopic column. The pin head is a round head or a roller head. The elastic limiting member provides elastic thrust to the bottom shell 9 in the horizontal direction. The elastic limiting structure 22 can be installed horizontally on the side wall of the placement slot 21, or it can be arranged slightly downward. The elastic limiting structure 22 can also adopt a spring sheet or elastic column structure, which can realize the lateral pushing of the bottom shell 9. The elastic limiting component drives the limiting strip to squeeze the side of the bottom shell 9, so that the other side of the bottom shell 9 is in contact with the positioning reference surface 23 to achieve reference positioning. The elastic limiting component is mainly used to limit the position of the bottom shell 9 in the horizontal direction. It does not support the bottom shell 9 in the vertical direction, so as not to affect the contact between the bottom surface of the bottom shell 9 and the floating reference plate 24. The design direction of the elastic limiting component is mainly lateral positioning. It has room for clearance or elastic deformation in the vertical direction and does not constitute vertical support for the bottom shell 9, so as to avoid affecting the contact between the bottom shell 9 and the floating reference plate 24 under its own weight.Furthermore, the adaptive positioning component also includes a floating reference structure, which is located at the bottom of the placement slot 21. The floating reference structure includes a floating reference plate 24 and an elastic support member 25 disposed below it. Under the restriction of the elastic support member 25, the floating reference plate 24 is only allowed to move in the height direction. The elastic support member 25 adopts a two-stage sliding telescopic column structure with built-in springs, and the built-in springs are pre-compressed, so that the floating reference plate 24 can move within a certain range and can undergo slight deformation under the weight of the bottom shell 9 itself. At the same time, the limiting strip in the elastic limiting structure 22 will contact the side of the bottom shell 9. There is slight friction and contact angle at the contact point, which will generate a small downward component force, which will also drive the bottom shell 9 to move downward. Combined with the weight of the bottom shell 9 itself, it triggers the height compensation of the floating reference plate 24. Under the weight of the bottom shell 9 and the pre-compression of the elastic support member 25, the floating reference plate 24 automatically fits the bottom surface of the bottom shell 9. Height compensation is achieved under pressure, and the floating reference plate 24 does not rely on external clamping force, but rather on the weight of the bottom shell 9 and the pre-pressure of the elastic support member 25 to perform micro-height compensation. This compensation is quasi-static leveling and will not cause swaying or instability. Furthermore, the floating reference plate 24 is supported by at least three non-collinearly distributed elastic support members 25, each of which has elastic displacement capability. The connection between the elastic support member 25 and the floating reference plate 24 is restricted, allowing only micro-angle adjustment to compensate for unevenness of the bottom surface of the bottom shell 9. This adjustment is quasi-static leveling and does not affect the stability of the dispensing. Specifically, the top of the elastic support member 25 has a ball head, and a shallow ball socket matching the ball head is provided at the bottom of the floating reference plate 24. The top of the elastic support member 25 and the floating reference plate 24 adopt a spherical contact structure, so that the floating reference plate 24 can produce a slight tilt when subjected to uneven force, thereby achieving adaptive attitude adjustment. Of course, the elastic support 25 can also be made of a flexible material with elastic deformation capability, such as a rubber column, so that the floating reference plate 24 can produce small posture changes when subjected to force at different support points. Under the action of the elastic support 25, the floating reference plate 24 forms a stable support plane. The bottom shell 9 fits with the floating reference plate 24 under its own weight and limiting action, so that the top surface of the bottom shell 9 maintains a consistent posture reference with respect to the dispensing assembly 3. The floating reference plate 24 is used to establish a relative reference plane required for the dispensing process, rather than for absolute level correction. When there is unevenness or thickness difference at the bottom of the bottom shell 9, the floating reference plate 24 forms a stable reference plane under the action of three elastic support points to achieve posture adaptive compensation.

[0030] like Figure 4As shown, the dispensing assembly 3 further includes a three-axis moving module and a dispensing valve 34. The three-axis moving module includes an X-axis linear moving module 31, a Y-axis linear moving module 32, and a Z-axis linear moving module 33. The dispensing valve 34 is located on the Z-axis linear moving module 33. The three-axis moving module enables the dispensing valve 34 to move in the X, Y, and Z axis directions, thereby moving the dispensing valve 34 to the required dispensing position on the bottom shell 9. A lifting cylinder 35 is provided on the worktable 11. A strip plate 36 is fixedly connected to the output end of the lifting cylinder 35. At least one proximity switch 37 is installed on the strip plate 36. The proximity switch 37 is located close to the dispensing valve 34. After the fixture assembly on the turntable 12 rotates to the proximity switch 37, it stops rotating, thereby realizing static dispensing of the bottom shell 9.

[0031] The working principle of the electronic device bottom shell dispensing inspection equipment provided by this invention is as follows: The feeding mechanism 5 uses negative pressure to adsorb the bottom shell 9 and places the bottom shell 9 into the placement slot 21 of the fixture assembly 2. The rotation of the fixture assembly 2, which contains the bottom shell 9, moves it to the dispensing station. After the proximity switch 37 senses the bottom shell 9, the turntable 12 stops rotating. The three-axis moving module moves the dispensing valve 34 to the bottom shell 9 to perform the dispensing operation. Then, the turntable 12 continues to rotate, moving the dispensed bottom shell 9 to the inspection station. The vision inspection unit 41 on the inspection mechanism inspects the dispensing quality on the bottom shell 9. After the inspection is qualified, the turntable 12 moves the bottom shell 9 to the unloading station. The unloading mechanism 6 removes the bottom shell 9 from the fixture assembly 2. The entire operation process is carried out synchronously. The adaptive positioning component can adaptively position the bottom shell 9 to absorb the dimensional tolerance and placement error of the bottom shell 9, improve the positioning consistency of the bottom shell 9, ensure the stability of the dispensing height and posture of the bottom shell 9 in subsequent processes, and improve the consistency of dispensing quality and the reliability of the inspection results.
