Description

Technical Field

[0001] The present invention relates to the technical field of display screen production equipment, and in particular to a gluing auxiliary device for display screen production. Background Art

[0002] During the production of the display screen, there is a gluing process, which is used to bond the middle frame and the display panel and form a certain degree of sealing, such as Figure 1 As shown, the middle frame 7 includes a surrounding wall 71 and an inwardly protruding support edge 72. The support edge 72 and the surrounding wall 71 are generally an integrated structure. Double-sided tape or glue (named as the first glue portion 91) is provided on the support edge 72 for bonding the display panel 8. In order to further improve the bonding effect between the display panel 8 and the middle frame 7, some display screens not only bond the support edge 72 to the back of the display panel 8, but also connect the inner wall of the surrounding wall 71 to the peripheral wall of the display panel 8 through glue (named as the second glue portion 92). In actual operation, the glue is directly injected into the gap between the surrounding wall 71 and the display panel 8. Since the back of the display panel 8 is glued to the support edge 72 in advance, the glue injected into the gap will not flow into the interior of the middle frame 7.

[0003] However, as display screens develop towards being thinner and more highly integrated, some display screen products require a window 73 to be opened on the frame 7, and the support edge 72 is disconnected in the area corresponding to the window 73 to form a vacant position. The window 73 can be used to install speakers, lighting components or other components. However, due to the existence of the vacant position on the support edge 72, during the process of applying glue to the gap between the surrounding wall 71 and the display panel 8, the glue will flow down at the position of the gap corresponding to the window 73. An additional process is required to wipe off the glue dripping into the window 73 or to scrape off the glue solidified on the window 73. If the residual glue in the window 73 is left unattended, it will affect the installation of the speaker, lighting components or other components and the appearance of the display screen. To overcome this problem, there are generally two measures in the existing technology. One is not to apply glue to the vacant position of the gap corresponding to the support edge 72, so that the local area of ​​the gap is lacking glue, but this will undoubtedly reduce the stability and sealing of the connection between the display panel 8 and the middle frame 7; the other is to set an additional process to wipe the glue at the window 73 or scrape off the colloid at the window 73 after the gap is glued. This will undoubtedly reduce the production efficiency of the display screen and increase the manufacturing cost of the display screen. Summary of the Invention

[0004] The technical problem solved by the present invention is to provide a gluing auxiliary device for display screen production that can take into account both production efficiency and product quality.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a gluing auxiliary device for display screen production, comprising:

[0006] A table top, wherein a first limiting strip and a second limiting strip are fixedly provided on the table top, wherein the first limiting strip and the second limiting strip are perpendicular to each other;

[0007] a first driving mechanism, the first driving mechanism comprising a first linear driving member and a third limiting bar, the third limiting bar being arranged opposite to the second limiting bar, the first linear driving member connecting the platform and the third limiting bar to drive the third limiting bar toward or away from the second limiting bar;

[0008] a second driving mechanism, the second driving mechanism comprising a second linear driving member and a fourth limiting bar, the fourth limiting bar being arranged opposite to the first limiting bar, the second linear driving member connecting the table and the fourth limiting bar to drive the fourth limiting bar toward or away from the first limiting bar; the first limiting bar, the second limiting bar, the third limiting bar and the fourth limiting bar limiting a placement position for placing the middle frame;

[0009] A collecting block, the collecting block being arranged on the fourth limiting strip and being located on a side of the fourth limiting strip close to the first limiting strip, the collecting block being provided with a flow channel, the flow channel comprising an isosceles trapezoidal segment and a DC segment, the large-diameter end of the isosceles trapezoidal segment being connected to the top surface of the collecting block, the small-diameter end of the isosceles trapezoidal segment being connected to the top of the DC segment, and the bottom end of the DC segment being connected to the bottom surface of the collecting block; the collecting block being further provided with a chute connecting its two ends, the middle area of ​​the chute being connected to the DC segment;

[0010] A partition is slidably disposed in the slide groove, and the partition controls the on-off state of the top end of the DC segment and the bottom end of the DC segment.

[0011] The beneficial effects of the present invention are:

[0012] The gluing auxiliary device for display screen production has a novel structure. The cooperation of the first limit bar, the second limit bar, the third limit bar and the fourth limit bar can accurately position the display hollow, which is beneficial to ensure the gluing accuracy of the gap between the wall of the middle frame and the display panel, and improve the product quality of the display screen.

[0013] When the fourth limit bar contacts the middle frame, the collecting block on the fourth limit bar can pass through the window of the middle frame, and the large diameter end of the isosceles trapezoidal segment is aligned and connected with the area of ​​the aforementioned gap corresponding to the window. Therefore, when glue is injected into the area of ​​the aforementioned gap corresponding to the window, even if the glue drips from the gap, it will only drip into the flow channel of the collecting block, so that it is collected by the flow channel of the collecting block. After the collecting block exits the window, no glue or colloid will remain outside the window. Therefore, there is no need to set up an additional process of wiping the glue / scraping off the colloid, which is beneficial to improving the production efficiency and product quality of the display screen.

[0014] After the glue in the flow channel solidifies or the glue volume reaches a certain level, the direct current section can be changed from a blocked state to a connected state by sliding the partition, so that the glue in the flow channel can flow out from the bottom of the flow channel, or the glue in the flow channel can be poked out with a tool to clean the flow channel.

[0038] Example 1

[0039] Please refer to Figures 2 to 6 Embodiment 1 of the present invention is: a gluing auxiliary device for display screen production, used to assist in gluing the gap between the inner wall of the surrounding wall 71 of the middle frame 7 and the peripheral wall of the display panel 8 to form a second glue portion 92, and the top surface of the supporting edge 72 of the middle frame 7 and the bottom surface of the display panel 8 are connected by the first glue portion 91.

[0040] The gluing auxiliary device for display screen production includes a platen 1, a first driving mechanism, a second driving mechanism, a collecting block 3 and a partition 4. The platen 1 is fixed with a first limiting bar 51 and a second limiting bar 52, and the first limiting bar 51 and the second limiting bar 52 are perpendicular to each other; the first driving mechanism includes a first linear driving member 21 and a third limiting bar 53, the first linear driving member 21 is a cylinder or an electric push rod, the third limiting bar 53 is arranged opposite to the second limiting bar 52, and the first linear driving member 21 connects the platen 1 and the third limiting bar 53 to drive the third limiting bar 53 Close to or away from the second limit bar 52; the second driving mechanism includes a second linear driving member 22 and a fourth limit bar 54, the second linear driving member 22 is a cylinder or an electric push rod, the fourth limit bar 54 is arranged opposite to the first limit bar 51, and the second linear driving member 22 connects the table 1 and the fourth limit bar 54 to drive the fourth limit bar 54 close to or away from the first limit bar 51; the first limit bar 51, the second limit bar 52, the third limit bar 53 and the fourth limit bar 54 limit the placement position for placing the middle frame 7; the collecting block 3 is arranged at the first limit bar 51; On the fourth limit bar 54 and located on the side of the fourth limit bar 54 close to the first limit bar 51, a flow channel 31 is provided on the collection block 3, and the flow channel 31 includes an isosceles trapezoidal section 311 and a DC section 312. The vertical cross-section of the isosceles trapezoidal section 311 is an isosceles trapezoid, and the vertical cross-section of the DC section 312 is a rectangle. The large diameter end of the isosceles trapezoidal section 311 is connected to the top surface of the collection block 3, the small diameter end of the isosceles trapezoidal section 311 is connected to the top of the DC section 312, and the bottom end of the DC section 312 is connected to the bottom surface of the collection block 3; the collection block 3 is also provided with a connection between the two ends thereof. The slide groove 32 at the end, the middle area of ​​the slide groove 32 is connected to the DC section 312; the partition 4 can be slidably arranged in the slide groove 32, and the partition 4 controls the on-off state of the top end of the DC section 312 and the bottom end of the DC section 312. When the partition 4 and the DC section 312 are misaligned, the top and bottom ends of the DC section 312 are in a connected state. At this time, the flow channel 31 can be cleaned. When the partition 4 closes the DC section 312, the upper and lower parts of the DC section 312 are separated by the partition 4. At this time, the residual glue in the flow channel 31 will not flow into the lower part of the DC section 312.

[0041] Specifically, the collecting block 3 has a first position and a second position. When the collecting block 3 is in the first position, the distance between the fourth limit bar 54 and the first limit bar 51 reaches the shortest state. At this time, the middle frame 7 is clamped and limited by the first limit bar 51, the second limit bar 52, the third limit bar 53 and the fourth limit bar 54; when the collecting block 3 is in the second position, the distance between the fourth limit bar 54 and the first limit bar 51 reaches the longest state, and the middle frame 7 can be taken and placed at this time.

[0042] The platen 1 is provided with a leak hole 11, which corresponds to the direct current section 312 on the collecting block 3 in the second position. When viewing the display screen glue-applying auxiliary device from a top-down perspective, the projection of the direct current section 312 lies within the projection of the leak hole 11. When the top and bottom ends of the direct current section 312 are connected, the glue in the flow channel 31 can fall through the leak hole 11, thereby restoring the flow channel 31's ability to store glue. Alternatively, solidified glue in the flow channel 31 can be prodded downward with a tool, causing it to fall through the leak hole 11, thereby restoring the flow channel 31's ability to store glue.

[0043] As a preferred embodiment, the gluing auxiliary device for display screen production also includes a lifting mechanism, which includes a lifting drive 61 and a top block 62. The lifting drive 61 is a cylinder or an electric push rod. The lifting drive 61 is located below the table 1 and is connected to the table 1 through a connecting member. A through hole 12 is provided on the table 1. The top block 62 can be lifted and lowered in the through hole 12. The output end of the lifting drive 61 is connected to the top block 62. The top block 62 is used to push against the front bottom of the collecting block 3 in the second position. In this way, when poking the colloid in the flow channel 31, the front end of the collecting block 3 can be supported by the top block 62, thereby reducing the risk of damage to the second driving mechanism when cleaning the flow channel 31, which is conducive to extending the service life of the second driving mechanism.

[0044] By controlling the size of the collecting block 3, the outline size of the vertical cross section of the collecting block 3 can be made the same as the size of the vertical surface of the window 73, so that the overflowed glue in each area of ​​the gap corresponding to the window 73 can be effectively collected by the collecting block 3. Figure 3 and Figure 4 As shown, the transverse cross-sectional dimension of the flow channel 31 is greater than the width of the gap. When the collecting block 3 is in the first position, at the window 73, the inner wall of the surrounding wall 71 and the peripheral wall of the display panel 8 are both located between the two inner wall surfaces of the flow channel 31, so that the overflowed glue can be better collected. At the same time, when the collecting block 3 moves from the first position to the second position, the edge of the top of the flow channel 31 can also scrape off the overflowed glue at the gap, which is beneficial to further improve the collection effect of the collecting block 3 on the glue liquid.

[0045] The above are only optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
