Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings and examples. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other technical solutions obtained by a person skilled in the art based on the examples in the present application fall within the scope of protection of the present application.

When the screen bonding is performed on the electronic equipment such as a mobile phone, a tablet and the like, the side edge of the screen can overflow the sizing material, so that the performance and subsequent assembly of the electronic equipment are affected. In the prior art, the spilled stock is typically cleaned manually. Along with the continuous increase of the demands of electronic equipment and the gradual increase of labor cost, the traditional manual glue cleaning mode has low glue cleaning efficiency and poor glue cleaning effect, and can not meet the production demands. Along with the increasing importance of the production speed of electronic products, especially mobile phones, the production speed needs to be increased in each process section, wherein the process section for cleaning the spilled glue on the mobile phone screen also needs to be transited from traditional manual glue cleaning to machine glue cleaning.

Based on the above-mentioned problems, embodiments of the present application provide a screen glue cleaner to at least partially solve the above-mentioned technical problems.

Specific implementations of embodiments of the present application are described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the screen glue cleaner of the embodiment of the present application includes a base 10 and a glue scraping assembly 20. The base 10 includes a table 11 and a truss 12, wherein the truss 12 is mounted to the 1A end of the table 11; the scraping assembly 20 comprises a scraper 21, a moving mechanism, a driving mechanism and a screen bearing table 23, wherein the scraper 21 is arranged on the truss 12, and the length direction of the scraper 21 is perpendicular to the workbench 11; the moving mechanism is installed on the workbench 11, the screen bearing table 23 is installed on the moving mechanism, and the driving mechanism drives the moving mechanism to move in a first plane so as to drive a screen borne by the screen bearing table 23 to rotate around the scraper 21 from a point at the edge of the screen at the scraping position to finish glue cleaning, wherein the first plane is a plane where the workbench 11 is located, and the position of the scraper 21 in the first plane is unchanged.

If the overflow glue on the edge of the screen is cleaned, the scraper and the screen need to move relatively, that is, the scraper moves around the edge of the screen, or the scraper is not moved, and the screen moves around the scraper. If the scraper moves around the edge of the screen, the scraper needs to be controlled to move in the horizontal direction (i.e. the first plane) and the scraper needs to be controlled to move in the vertical direction, so that the structure and the control system of the glue cleaner are complex. Thus, in this application, a control mode is used in which the screen moves around the doctor blade.

The screen glue cleaner of the embodiment can control the mobile phone screen to move around the scraper at the fixed position on the horizontal plane to realize glue scraping, thereby realizing automatic glue scraping, greatly improving the production efficiency and saving the labor cost.

Specifically, as shown in fig. 2, the motion mechanism includes an X-axis assembly 221, a Y-axis assembly 222, and an R-axis assembly 223, the driving mechanism includes an X-axis driver, a Y-axis driver, and an R-axis driver, the Y-axis assembly 222 is fixedly connected with the table 11, the X-axis assembly 221 is movably connected with the Y-axis assembly 222, the R-axis assembly 223 is movably connected with the X-axis assembly 221, and the screen bearing table 23 is rotatably connected with the R-axis assembly 223, wherein the Y-axis driver drives the X-axis assembly 221 to move Y along the Y-axis; the X-axis driver drives the R-axis assembly 223 to move along the X1 axis; the R-axis driver drives the screen bearing table 23 to rotate along the R-axis; the plane where the X axis and the Y axis are located is a first plane, the X axis is perpendicular to the Y axis, and the R axis is a central axis of the screen bearing table perpendicular to the first plane.

To achieve one movement of the screen around the fixed position doctor blade, at least three axes of movement are required to drive the screen stage, namely the horizontal axis of movement X, the horizontal axis of movement Y and the axis of rotation R. Correspondingly, to realize the movement mode, an X-axis component 221, a Y-axis component 222 and an R-axis component 223 are arranged, and a Y-axis actuator drives the X-axis component 221 to move Y301 along the Y-axis; the X-axis driver drives the R-axis assembly 223 to move along the X1 axis; the R-axis driver drives the screen bearing table 23 to rotate along the R-axis, thereby realizing motion control of the screen.

As shown in fig. 1, the doctor assembly 20 further includes a positioning device 24, where the positioning device 24 is mounted at a loading position located at the 1B end of the table 11.

As shown in fig. 1, the 1B end of the table 11 is a loading position. The worker or the manipulator places the screen to be cleaned on the screen bearing table at the feeding position, and takes the cleaned screen off the screen bearing table. The doctor blade is located at a doctor position, i.e. the doctor position is close to the 1A end of the table 11. The device and the parts at the end 1A are more, which is unfavorable for feeding operation, so that the feeding position is arranged at the end 1B far away from the end 1A.

In the process of feeding, the screen must be placed at a preset position of the bearing table, the preset position is a positioning reference of the screen, if the screen is not aligned to the preset position, interference between the scraper at the scraping position and the edge of the screen can be caused, or the distance between the scraper at the scraping position and the edge of the screen is larger, so that the scraping effect is affected and even the screen is damaged. And it is difficult to secure the placement position of the screen against the observation of the robot or worker, and therefore, the positioning device 24 is provided at the loading position to secure the screen to be placed at the preset placement position.

Specifically, as shown in fig. 1, the positioning device 24 includes a bracket 241, a fixed jig 242, a first movable jig 243, a second movable jig 244, a first driver, and a second driver. As shown in fig. 1 and 3, the fixing clamp 242 is L-shaped, a first side of the fixing clamp 242 is fixedly connected to the bracket 241, the first movable clamp 243 is slidably connected to the bracket 241, and the second movable clamp 244 is rotatably connected to a free end of a second side of the fixing clamp 242, as shown in fig. 1. The first driver drives the first movable clamp 243 to move in the X2 axis direction (i.e., in a direction approaching the fixed clamp); the second actuator drives the second movable fixture 244 to rotate about the Z1 axis, thereby opening and closing the positioning device 24.

Specifically, the inner side of the first side and the inner side of the second side of the positioning jig serve as positioning reference sides. The positioning device 24 has an open state and a positioning state, and before loading, the positioning device 24 should be in the open state, as shown in fig. 1, that is, the first movable clamp 243 is located away from the fixed clamp 242, and the second movable clamp 244 is in the open state, that is, the second movable clamp 244 is parallel to the second side of the fixed clamp 242. After the manipulator or worker places the screen to be cleaned on the screen carrying table, the first driver drives the first movable clamp 243 to translate in the X2 axis direction (the direction close to the fixed clamp 242), and the second driver drives the second movable clamp 244 to rotate around the free end of the second side of the fixed clamp 242 in the counterclockwise direction until the second side is perpendicular to the first side, and at this time, the positioning clamp is in a positioning state. The screen is tightly attached to the inner side of the first side and the inner side of the second side of the fixing jig 242 by the first and second movable jigs 243 and 244 as shown in the (1) drawing of fig. 3, thereby completing the positioning.

Specifically, in one implementation, the first driver and the second driver are cylinders. The cylinder has simple structure, easy installation and maintenance and low use cost.

In other embodiments, the first driver and the second driver may be driving mechanisms such as a cylinder and a servo motor.

Specifically, the drive mechanism is configured to: the driving movement mechanism moves to drive the screen bearing table to move between the feeding position and the glue scraping position.

After the loading of the loading position is completed, the first movable clamp 243 is moved in a direction away from the fixed clamp 242, and the second movable clamp 244 is rotated in a clockwise direction, thereby opening the fixing device, as shown in fig. 3 (2). The driving mechanism then drives the screen bearing table 23 to move in the direction of the doctor blade position. It should be noted that, before the screen is completely separated from the fixing device, the screen can only be driven by the Y axis to move (if the screen is not completely separated from the fixing device, the screen is driven by the X axis to move, which causes the screen to collide with the first movable clamp 243), as shown in the (3) diagram in fig. 3. After the screen bearing table 23 is completely separated from the positioning device 24, the X-axis driver and the Y-axis driver synchronously drive the screen bearing table 23 to move towards the doctor position, as shown in a (4) diagram in fig. 3. In other embodiments, the screen stage 23 is driven by the Y-axis to move along the Y-axis direction until the screen stage 23 is aligned with the doctor position, and then the X-axis driver drives the screen stage 23 to move to the doctor position. The position shown in the figure (5) in fig. 3 is the doctor blade position. After the screen bearing table 23 reaches the doctor blade position, the X-axis, Y-axis and R-axis synchronously drive the screen bearing table 23 to rotate around the doctor blade to complete the cleaning of the glue, as shown in the (6) drawing in fig. 3.

Specifically, in an embodiment that can be realized, the screen bearing table 23 is provided with an adsorption device 231, and the adsorption device 231 is used for adsorbing the screen to be cleaned on the screen bearing table 23. The adsorption device can tightly adsorb the screen on the screen bearing table 23, so that the sliding in the moving process is avoided.

As shown in fig. 1, the doctor assembly 20 further includes a hopper 25, the hopper 25 being mounted below the doctor blade. The hopper 25 is used for receiving and storing scraped over glue 81.

Specifically, in one implementation, the scraper has a plurality of scraping positions, and the scraping positions are arranged at intervals along the length direction of the scraper, and the driving mechanism further comprises a Z-axis driver, and the Z-axis driver drives the scraper to move along the length direction of the scraper.

If the same scraping position on the scraper is always used for scraping, the scraping effect is possibly influenced due to the abrasion of the scraper, and the overflow glue cannot be cleaned, so in the embodiment of the application, the scraper is provided with a plurality of scraping positions, and the scraper moves to the next scraping position after working for a preset time or a preset number of times at the current scraping position, thereby effectively avoiding the influence on the scraping effect due to excessive abrasion of the scraper.

Specifically, in order to improve the spreading efficiency, the screen glue cleaner is provided with N groups of spreading assemblies 20, and the spreading assemblies 20 are arranged at intervals along the X3 axis direction, wherein N is greater than or equal to 2. Illustratively, as shown in fig. 1, the screen cleaner of the present embodiment is configured with 2 sets of doctor assemblies 20.

The following describes the working flow of the screen glue cleaner provided in the embodiment of the present application with reference to fig. 4.

As shown in fig. 4, the screen is placed on the screen bearing table manually or by a manipulator, then the start button is pressed, the first driver drives the first sliding clamp to act, the second driver drives the second movable clamp to act, so that the screen is attached to the inner side of the fixed clamp, and meanwhile, the control system automatically generates motion control information of the X axis, the Y axis and the R axis. The X axis and the Y axis respectively perform a tiny positioning and leave the mechanical structure, then the Y axis acts to drive the screen bearing table to move along the Y axis direction, and meanwhile, whether the Y axis enters a safe area or not is judged (namely, whether the screen bearing table is completely separated from the positioning device or not); after the Y axis is judged to enter the safety area, the X axis and the Y axis act to move the screen bearing table to the glue scraping position, if the Y axis is judged not to enter the safety area, the machine is stopped in a fault mode, and the touch screen displays specific fault information. After the screen bearing table reaches the scraping position, the X axis, the Y axis and the R axis synchronously act, and the screen is driven to rotate along the scraper for one circle to finish scraping. After the scraping is finished, the screen bearing table moves to a loading position to wait.

While the utility model has been illustrated and described in detail in the drawings and in the preferred embodiments, the present application is not limited to the disclosed embodiments, and it will be appreciated by those skilled in the art that the code audits of the various embodiments described above may be combined to obtain further embodiments of the present application, which are also within the scope of the utility model.
