[0044] The vacuum glue pouring mechanism and glue pouring equipment according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Reference Figures 1 to 3 As shown, the vacuum glue pouring mechanism provided in the embodiment of the present invention is used for pouring glue into the glue pouring product 40, the glue pouring product 40 has a glue inlet hole 401 and a glue outlet hole 402, the glue inlet hole 401 and the glue outlet hole 402 are connected to each other via a cavity 403 in the glue pouring product 40, the vacuum glue pouring mechanism includes a floating plate 10, a glue pouring assembly 20 and a glue extraction assembly 30, the floating plate 10 can move in a vertical direction when driven; the glue pouring assembly 20 is arranged on the floating plate 10, and is used to extend into the glue inlet hole 401 to pour the glue into the cavity 403; the glue extraction assembly 30 is arranged on the floating plate 10 and is adjacent to the glue pouring assembly 20, and is used to extend into the glue outlet hole 402 to vacuum the cavity 403, so that the glue flows out from the glue outlet hole 402.

[0046] Among them, the glue-filled product 40 can be a CG glass cover plate, an aluminum alloy cover plate, a ceramic cover plate, etc. The glue inlet hole 401 and the glue outlet hole 402 of the glue-filled product 40 can be used to bond parts respectively. A plurality of overflow holes are respectively provided at the positions of the glue inlet hole 401 and the glue outlet hole 402. When the colloid is poured into the glue inlet hole 401, since the cavity 403 is vacuumed, the colloid can enter the cavity 403, and after the cavity 403 is filled, it overflows from the overflow hole, and then the parts are bonded at the positions of the glue inlet hole 401 and the glue outlet hole 402 in the subsequent assembly process. It can be understood that the colloid can overflow from the overflow hole when the cavity 403 is filled, so that the glue filling rate is faster and the glue filling effect is better.

[0047] The vacuum glue pouring mechanism provided by the present invention can drive the glue pouring component 20 to extend into the glue inlet hole 401 and pour glue into the cavity 403 when the floating plate 10 is driven. At the same time, the glue extraction component 30 extends into the glue outlet hole 402 to vacuum the cavity 403, so that the glue can be completely filled in the cavity 403 and flow out from the glue outlet hole 402, so that the glue flow rate is faster, the glue pouring rate is faster, and the production capacity is effectively improved.

[0048] Reference Figure 4 As shown, the glue extraction assembly 30 includes a first adjustment plate 31, a second adjustment plate 32 and a third adjustment plate 33. The first adjustment plate 31 has a vertical end and a horizontal end. The vertical end is movably connected to the floating plate 10 along the vertical direction; one end of the second adjustment plate 32 is movably connected to the horizontal end; the third adjustment plate 33 is movably connected to the other end of the second adjustment plate 32.

[0049] Furthermore, the vertical end has a first strip hole 311 extending in the vertical direction, and the first strip hole 311 is connected to the floating plate 10; the horizontal end has a second strip hole 312 extending in the horizontal direction, and the third adjustment plate 33 is provided with a third strip hole 331 extending in the horizontal direction, the second strip hole 312 and the third strip hole 331 are perpendicular to each other, and the connecting holes 321 provided at both ends of the second adjustment plate 32 are respectively connected to the second strip hole 312 and the third strip hole 331.

[0050] In this embodiment, the connecting seat 34 is connected to the third adjustment plate 33, and the glue extraction head 35 is arranged at the lower end of the connecting seat 34. The first strip hole 311 and the floating plate 10 can be fixed by bolts. When adjusting the vertical height of the glue extraction head 35, the first adjustment plate 31 is moved and adjusted in the vertical direction, so that the height of the connecting seat 34 and the glue extraction head 35 can be adjusted in the vertical direction along with the first adjustment plate 31; and the connecting holes 321 at both ends of the second adjustment plate 32 can be fixed with the second strip hole 312 and the third strip hole 331 by bolts. When adjusting the horizontal position of the glue extraction head 35, In order to align it with the glue outlet hole 402, the relative positions of the second adjustment plate 32 and the first adjustment plate 31 can be adjusted, as well as the relative positions of the third adjustment plate 33 and the second adjustment plate 32, so that the horizontal position of the glue extraction head 35 is adjusted to align with the glue outlet hole 402; it can be understood that the three-axis directions of the glue extraction head 35 can be moved and adjusted through the first adjustment plate 31, the second adjustment plate 32 and the third adjustment plate 33, the adjustment operation is simpler, and the spacing between the glue extraction head 35 and the glue-filled product 40 and the accuracy of the glue outlet hole 402 can be ensured to be more accurate.

[0051] Reference Figure 3 and Figure 4As shown, the glue extraction assembly 30 includes a connecting seat 34, a glue extraction head 35, an elastic member 36 and a vacuum joint 37. The upper end of the connecting seat 34 is connected to the third adjustment plate 33; the glue extraction head 35 is sleeved on the lower end of the connecting seat 34; the elastic member 36 is sleeved on the connecting seat 34 and abuts against the glue extraction head 35; the vacuum joint 37 is provided on the glue extraction head 35, and is used to connect to a vacuum device to vacuum the glue extraction head 35.

[0052] In this embodiment, the vacuum equipment can be connected to the vacuum joint 37 through an air pipe. During the glue pouring and vacuuming process, the glue pouring component 20 follows the floating plate 10 to align with the glue inlet hole 401 and presses down to pour glue, and the glue extraction head 35 follows the floating plate 10 to align with the glue outlet hole 402, so that glue pouring and vacuuming can be carried out at the same time, thereby improving the glue pouring rate; and when the glue extraction head 35 is pressed down on the glue outlet hole 402, the elastic member 36 can elastically buffer the glue extraction head 35 to prevent the glue extraction head 35 from crushing the glue-filled product 40, thereby improving the yield rate of the glue-filled product 40.

[0053] Specifically, a detection sensor 38 is disposed on the top of the connection seat 34 , and the detection sensor 38 is used to detect the glue in the glue hole 402 to control the glue filling component 20 to start or stop.

[0054] In this embodiment, the detection sensor 38 can be electrically connected to the main controller to realize signal transmission control, and the connecting seat 34 is connected to the glue extraction head 35. The detection sensor 38 can monitor whether the glue outlet hole 402 is discharging glue through the connecting seat 34 and the glue extraction head 35. When the glue outlet hole 402 is discharging glue, a signal is sent to enable the main controller to control the glue filling component 20 to stop filling glue; when the glue outlet hole 402 is not discharging glue, a signal is sent to enable the main controller to control the glue filling component 20 to start filling glue, so that its monitoring is more accurate and the glue filling effect is better.

[0055] Reference Figure 6 As shown, a vacuum valve 50 is also included, and the vacuum valve 50 is connected to the vacuum joint 37 to adjust the vacuum pressure of the glue extraction head 35. The vacuum device can be connected to the vacuum valve 50 through an air pipe, and the vacuum valve 50 is connected to the vacuum joint 37 through the air pipe. When adjusting the vacuum pressure of the glue extraction head 35, the vacuum pressure of the glue extraction head 35 can be adjusted through the vacuum valve 50, so that the glue extraction pressure of the glue extraction head 35 is controllable and the control is more accurate, avoiding the situation that the colloid is not extracted.

[0056] Reference Figure 5 As shown, the glue pouring assembly 20 includes a connecting plate 21 , two glue cylinders 22 and a glue pouring head 23 . The connecting plate 21 is arranged on the floating plate 10 ; the two glue cylinders 22 are arranged on the connecting plate 21 ; the glue pouring head 23 is arranged on the connecting plate 21 and is connected to the two glue cylinders 22 .

[0057] In this embodiment, the colloid can be AB glue. The two glue cylinders 22 can contain AB glue and mix the AB glue. After mixing, the mixture is injected into the glue pouring head 23, so that the glue pouring head 23 can be pressed down on the glue pouring product 40 for glue pouring; a spring is provided on the glue pouring head 23 to provide elastic buffering, so that when the glue pouring head 23 is pressed down for glue pouring, the buffering effect is better, and damage to the glue pouring head 23 or the glue pouring product 40 is avoided, and the safety is higher; it can be understood by those skilled in the art that since AB glue is in a colloid state close to a solid state and has a slow flow rate, the glue pouring rate is faster when the glue is poured through the glue pumping head 35.

[0058] Reference Figure 5 As shown, the floating plate 10 has a base plate 60 on the side facing away from the glue filling assembly 20, and the floating plate 10 is slidably connected to the base plate 60, and a cylinder 70 is provided on the base plate 60, and the cylinder 70 is used to drive the floating plate 10 to slide on the base plate 60 in the vertical direction. The piston rod of the cylinder 70 is connected to the floating plate 10, and when the piston rod of the cylinder 70 is extended, the floating plate 10 is driven by the cylinder 70 to move downward; when the piston rod of the cylinder 70 is retracted, the floating plate 10 is driven by the cylinder 70 to move upward, so that the glue filling head 23 and the glue extraction head 35 can be pressed down on the glue filling product 40 synchronously and leave the glue filling product 40 synchronously, which is more convenient and simple to use.

[0059] Furthermore, a tension spring 80 is included, one end of the tension spring 80 is connected to the base plate 60 , and the other end of the tension spring 80 is connected to the floating plate 10 .

[0060] In this embodiment, the tension spring 80 can overcome the gravity of the floating plate 10 and the glue potting assembly 20, so that the floating plate 10 has a better buffering effect during the rising or falling process, and can avoid damage to the glue potting product 40 caused by the gravity of the floating plate 10 and the glue potting assembly 20, and has better stability.
