Description

Technical Field

[0001] The utility model relates to the technical field of display panel manufacturing equipment, and in particular to a nozzle assembly and spraying equipment for manufacturing a display panel. Background Art

[0002] like Figures 1 to 3 As shown, in the process of manufacturing the display panel, it is necessary to use a spraying device 2' to spray liquid on the substrate 4' to manufacture a film layer on the substrate 4'. Specifically, in the production process, the substrate 4' is transported by the transport mechanism 3' to move relative to the spraying device 2' along the transport direction X'. The spraying device 2' sprays liquid on the substrate 4' through the nozzle assembly 1'. The nozzle assembly 1' includes two nozzle bodies 10' that are detachably connected. The nozzle body 10' is provided with a liquid injection hole 100', a liquid storage tank 101' and a liquid outlet channel 102' that are sequentially connected along a first direction S1'. The liquid storage tank 101' and the liquid outlet channel 102' are both connected to the nozzle body 10' along a second direction S1'. On the same side of the nozzle assembly 1' along the first direction S2', the liquid storage tanks 101' of the two nozzle bodies 10' are connected, and the liquid outlet channels 102' of the two nozzle bodies 10' are connected. The two liquid outlet channels 102' form a liquid outlet opening 10a' on one side of the nozzle assembly 1' along the first direction S1'. The length direction of the liquid outlet opening 10a' is perpendicular to the conveying direction X' of the mechanism conveying, wherein the first direction S1' is perpendicular to the second direction S2', and the length direction of the liquid outlet opening 10a' is perpendicular to the first direction S1' and the second direction S2'. Figure 1 The arrows in FIG. 1 show the conveying direction X'. Figures 1 to 3 The first direction S1' and the second direction S2' are shown in coordinates.

[0003] In order to improve production efficiency and reduce production costs, the related art generally uses a substrate 4' of uniform size, and produces multiple display panels on the same substrate 4' at the same time, so that most of the equipment used in the manufacturing process of the display panel only needs to be suitable for processing the substrate 4' of fixed size, among which, Figure 1 As shown in Figure 1 The dashed lines in the figure exemplarily show the edges of multiple display panels produced simultaneously on the same substrate 4'. The dashed lines are only used to indicate the edge positions of each display panel, and are not used to indicate the existence of a physical edge structure there. Therefore, in the related art, the length dimension of the liquid outlet opening 10a' of the nozzle assembly 1' is usually fixed, and the length dimension of the liquid outlet opening 10a' is greater than or equal to the board surface dimension of the substrate 4' along the direction perpendicular to the conveying direction X', so that when the substrate 4' moves relative to the nozzle assembly 1' along the conveying direction X', the liquid spraying range of the nozzle assembly 1' can cover the entire board surface of the substrate 4'.

[0004] However, when multiple display panels produced simultaneously on the same substrate 4' include display panels of different sizes, since the production requirements of display panels of different sizes are different, when the production of display panels of one size exceeds the demand, while the production of display panels of another size does not meet the demand, in the related technology, it is still necessary to use a spraying device 2' to spray the entire substrate 4' with liquid medicine to produce the complete substrate 4'. After the complete substrate 4' is manufactured, only the display panels of a size that does not meet the production requirement are cut, and the remaining display panels are discarded, resulting in huge waste.

[0045] The advantages and features of the present invention and the methods for achieving them will become apparent with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms. The present embodiments are provided only to complete the disclosure of the present invention and to enable those skilled in the art to fully understand the scope of the present invention, and the present invention is limited only by the scope of the claims. The same reference numerals represent the same constituent elements throughout the specification.

[0046] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0047] like Figures 4 to 8As shown, a nozzle assembly 1 for manufacturing a display panel is provided, comprising two nozzle bodies 10 and a gasket 11, the two nozzle bodies 10 are detachably connected, the nozzle body 10 is provided with a liquid injection hole 100 and a liquid storage tank 101 which are sequentially connected along a first direction S1, the liquid storage tank 101 has an opening 102 located on one side of the nozzle body 10 along a second direction S2, the openings 102 of the two nozzle bodies 10 are opposite and connected, the gasket 11 comprises a first part 111 and a second part 112 connected along a third direction S3, that is, the first part 111 is connected to one side of the second part 112 along the third direction S3, and the first part 111 is sandwiched at two opposite sides of the opening 102 between the two nozzle bodies 10 along the first direction S1. And along the first direction S1, the first part 111 covers the two openings 102, and a second part 112 is sandwiched between the two nozzle bodies 10 at a side of the opening 102 close to the injection hole 100 along the first direction S1, and along the first direction S1, the second part 112 does not completely cover the two openings 102. In other words, the second part 112 covers the parts of the two openings 102 close to the injection hole 100, or the second part 112 does not cover the two openings 102, and a liquid outlet channel 12 is formed between the side of the second part 112 away from the injection hole 100 along the first direction S1 and the two nozzle bodies 10, and the liquid outlet channel 12 is connected to the two openings 102, wherein the first direction S1, the second direction S2 and the third direction S3 are perpendicular to each other, such as Figures 4 to 8 As shown, Figure 4 and Figure 6 The coordinates in the figure show the first direction S1, the second direction S2 and the third direction S3. Figure 5 The coordinates in show the second direction S2 and the third direction S3, Figure 7 and Figure 8 The coordinates in show the first direction S1 and the second direction S2.

[0048] The nozzle assembly 1 for manufacturing a display panel of the utility model is provided with a gasket 11 including a first part 111 and a second part 112, so that the first part 111 is sandwiched at two opposite sides of the opening 102 between the two nozzle bodies 10 along the first direction S1, and the first part 111 can cover the two openings 102 along the first direction S1, and at the same time, the second part 112 is sandwiched at one side of the opening 102 between the two nozzle bodies 10 along the first direction S1 close to the injection hole 100, and the second part 112 can only cover the parts of the two openings 102 close to the injection hole 100, or the second part 112 cannot cover the two openings 102, so that the first part 111 is sandwiched between the two nozzle bodies 10 at the opening 102 away from the injection hole 100 along the first direction S1, and a gap is formed at the position of the second part 112 away from the injection hole 100 along the first direction S1, and the gap is formed into a liquid outlet channel 12 connected to the two openings 102.

[0049] It can be understood that when the nozzle assembly 1 is in use, the third direction S3 of the nozzle assembly 1 is perpendicular to the transport direction of the transport mechanism 3 to transport the substrate 4 relative to the nozzle assembly 1. In other words, the spraying range of the nozzle assembly 1 on the substrate 4 is determined by the size of the liquid outlet channel 12 along the third direction S3, and the size of the liquid outlet channel 12 along the third direction S3 is determined by the relative position of the second part 112 and the two openings 102 along the third direction S3. In other words, it is determined by the relative position of the gasket 11 and the two openings 102 along the third direction S3. Therefore, after disassembling the two nozzle bodies 10, the relative position of the gasket 11 and the nozzle body 10 along the third direction S3 can be adjusted, and then the two nozzle bodies 10 can be connected to clamp the gasket 11 between the two nozzle bodies 10 to adjust the spraying range of the nozzle assembly 1, so that the nozzle assembly 1 can spray the liquid only on the area of ​​the substrate 4 that needs to be produced.

[0050] Please combine Fig. 9 As shown, along the third direction S3, the size of the opening 102 is s, and the size of the first part 111 is d1. Since the size d1 of the first part 111 determines the maximum size of the two openings 102 that can be blocked along the third direction S3, in other words, the size d1 of the first part 111 determines the minimum size of the liquid outlet channel 12 along the third direction S3. In actual production, the liquid outlet channel 12 is usually used to spray liquid on a portion of 1 / 2 to 2 / 3 of the substrate 4 along the third direction S3, so as to manufacture a display panel on a minimum portion of 1 / 2 to 2 / 3 of the substrate 4 along the third direction S3. Based on this, optionally, the size s and the size d1 can satisfy: 1 / 3≤d1 / s≤1 / 2, for example, d1 / s can be 1 / 3, 3 / 8, 5 / 12, 11 / 24 or 1 / 2, etc.

[0051] Along the third direction S3, the size of the second part 112 is d2. Since the size d2 of the second part 112 determines the maximum size of the parts of the two openings 102 that can be unobstructed along the third direction S3, in other words, the size d2 of the second part 112 determines the maximum size of the liquid outlet channel 12 along the third direction S3. In actual production, the liquid outlet channel 12 is usually used to spray the liquid on the entire substrate 4 along the third direction S3 to manufacture a display panel on the entire substrate 4. Based on this, optionally, the size s and the size d2 can satisfy: d2 / s≥1, for example, d2 / s can be 1, 1.1, 1.2, 1.3, 1.4 or 1.5, etc.

[0052] Preferably, the dimensions s, d1 and d2 can satisfy: 1 / 3≤d1 / s≤1 / 2, and d2 / s≥1, so that the structure of the gasket 11 is suitable for meeting the spraying range requirements of more types of nozzle assemblies 1 .

[0053] In addition, since the liquid outlet channel 12 is formed by the first part 111, the second part 112 and the two nozzle bodies 10, the size of the liquid outlet channel 12 along the second direction S2 is determined by the thickness of the gasket 11 along the second direction S2. Therefore, optionally, the size of the liquid outlet channel 12 along the second direction S2 can be adjusted by replacing the gasket 11 with different thicknesses, thereby adjusting the spray flow rate of the nozzle assembly 1, which can make the spray effect of the nozzle assembly 1 more flexible.

[0054] Since the flow path of the medicinal liquid from the liquid storage tank 101 to the liquid outlet channel 12 is determined by the area of ​​the partial opening 102 not covered by the second part 112, optionally, the area of ​​the partial opening 102 that can be covered by the second part 112 can be adjusted by adjusting the size of the second part 112 along the first direction S1, so as to adjust the flow path of the medicinal liquid from the liquid storage tank 101 to the liquid outlet channel 12, thereby achieving the effect of adjusting the spray flow rate of the nozzle assembly 1.

[0055] It can be understood that the effect of adjusting the spray flow rate of the nozzle assembly 1 can be achieved by only adjusting the thickness of the gasket 11 along the second direction S2, or only adjusting the size of the second part 112 along the first direction S1, or by simultaneously adjusting the thickness of the gasket 11 along the second direction S2 and the size of the second part 112 along the first direction S1.

[0063] like Figure 6 , Figures 10 to 12 As shown, optionally, the nozzle assembly 1 further includes two adjustment mechanisms 13, the two adjustment mechanisms 13 are respectively arranged on two opposite sides of the two nozzle bodies 10 as a whole along the third direction S3, the adjustment mechanism 13 includes a mechanism body 130 and a rotating shaft 131, the mechanism body 130 is provided with an internal accommodating groove 130a, and the mechanism body 130 is further provided with a connecting groove 130b connected to the accommodating groove 130a and the external space of the mechanism body 130 on one side along the first direction S1, the central axis of the rotating shaft 131 is parallel to the first direction S1, and the rotating shaft The first shaft 1311 and the second shaft 1312 are connected to each other. The first shaft 1311 can be rotatably arranged in the receiving groove 130a. The second shaft 1312 passes through the connecting groove 130b and extends to the outside of the mechanism body 130. The first shafts 1311 of the two adjustment mechanisms 13 are respectively connected to the two opposite ends of the gasket 11 along the third direction S3 by connection methods including but not limited to bonding, clamping, and welding. The rotating shaft 131 can rotate around its own central axis relative to the mechanism body 130 to reel in or unreel the gasket. 11, so that the two opposite ends of the gasket 11 along the third direction S3 (that is, the end of the first part 111 away from the second part 112, and the end of the second part 112 away from the first part 111) can be respectively rolled up or unrolled by the two adjusting mechanisms 13. On the one hand, when the gasket 11 is released from being clamped by the two nozzle bodies 10, the operator can rotate the two second shafts 1312 to adjust the relative posture of the first part 111, the second part 112 and the nozzle body 10 along the third direction S3. On the other hand, after adjusting the relative posture of the first part 111, the second part 112 and the nozzle body 10 along the third direction S3, before connecting the gasket 11 to the two nozzle bodies 10, the posture of the gasket 11 can be restricted to a certain extent by the two adjusting mechanisms 13, so that the gasket 11 can be kept in the adjusted posture more stably, avoiding a large change in the relative posture of the first part 111, the second part 112 and the nozzle body 10 along the third direction S3 after the gasket 11 is connected to the two nozzle bodies 10.

[0064] Optionally, the rotating shaft 131 is movably connected to the mechanism body 130 along the first direction S1, a first clamping structure 1311a is provided on the first shaft body 1311, and the mechanism body 130 is further provided with a second clamping structure 130d corresponding to the first clamping structure 1311a, and the second clamping structure 130d can at least be clamped to the first clamping structure 1311a along the first direction S1, so that the operator can drive the first clamping structure 1311a to disengage from the second clamping structure 130d by moving the second shaft body 1312 along the first direction S1, and then the second shaft body 1312 can be rotated. 312, so that the first shaft 1311 can unwind or reel in the gasket 11, thereby adjusting the relative posture of the first part 111, the second part 112 and the nozzle body 10 along the third direction S3. After the adjustment is completed, the operator can move the second shaft 1312 along the first direction S1 to drive the first clamping structure 1311a and the second clamping structure 130d to be clamped together, so that the posture of the rotating shaft 131 in the accommodating groove 130a is more stable, and then the posture of the gasket 11 can be limited, so that the relative posture of the gasket 11 and the two nozzle bodies 10 is easier to maintain stable.

[0065] Among them, the first clamping structure 1311a may include a clamping slot, and the second clamping structure 130d includes a clamping protrusion, or the first clamping structure 1311a may include a clamping protrusion, and the second clamping structure 130d includes a clamping slot, so that the first clamping structure 1311a and the second clamping structure 130d can be clamped along the first direction S1 by cooperating with the clamping slot and the clamping protrusion.

[0066] Further, there may be at least one latching protrusion and multiple latching slots, and multiple latching slots are arranged at intervals around the first shaft 1311, so that the rotating shaft 131 and the receiving slot 130a can be maintained in different relative postures by making the latching protrusion engage with different latching slots among the multiple latching slots. Specifically, when the first latching structure 1311a includes multiple latching slots, and the second latching structure 130d includes at least one latching protrusion, the outer periphery of the first shaft 1311 may be connected to a convex ring 1314, and multiple latching slots are arranged on the convex ring 1314 around the first shaft 1311. When the first latching structure 1311a includes at least one latching protrusion and the second latching structure 130d includes multiple latching slots, the multiple latching slots may be arranged around the first shaft 1311 at intervals on a side wall of the receiving slot 130a along the first direction S1.

[0067] Optionally, the second clamping structure 130d can be clamped to the first clamping structure 1311a along the direction from the connecting groove 130b to the receiving groove 130a, the groove diameter of the connecting groove 130b is smaller than the groove diameter of the receiving groove 130a, and the connecting part of the connecting groove 130b and the receiving groove 130a forms a step surface 130c facing the inside of the receiving groove 130a, the first clamping structure 1311a is located at the end of the first shaft body 1311 away from the second shaft body 1312, and a stop convex 1313 is further connected between the first shaft body 1311 and the second shaft body 1312, and the adjustment mechanism 13 further includes an elastic member 132, and the elastic member 13 The elastic member 132 may include but is not limited to a spring and a spring sheet. The elastic member 132 is connected between the step surface 130c and the stop protrusion 1313. The elastic member 132 can apply an elastic force to the stop protrusion 1313, so that the stop protrusion 1313 always has a tendency to move away from the step surface 130c. Therefore, when the adjustment mechanism 13 is not subjected to an additional external force, the elastic force applied by the elastic member 132 to the stop protrusion 1313 can keep the first clamping structure 1311a in a state of being clamped with the second clamping structure 130d. In other words, the first clamping structure 1311a can maintain a better clamping stability with the second clamping structure 130d.

[0068] Optionally, a handle 1312a is further provided on the outer periphery of the second shaft body 1312 , and the handle 1312a is used for an operator to grasp, so that the operator can rotate or move the second shaft body 1312 by rotating or moving the handle 1312a .

[0069] Optionally, the two adjustment mechanisms 13 are fixedly connected to the same nozzle body 10, so that when adjusting the relative position of the gasket 11 and the nozzle assembly 1, the two nozzle assemblies 1 can be detached first. At this time, the two adjustment mechanisms 13 are separated from the non-fixedly connected nozzle assembly 1, and the relative positions of the two adjustment mechanisms 13 and the fixedly connected nozzle assembly 1 remain unchanged. Then, the operator adjusts the relative posture of the first part 111, the second part 112 and the nozzle body 10 along the third direction S3 by rotating and moving the second shaft 1312. Finally, the two nozzle assemblies 1 are connected to complete the size adjustment operation of the liquid outlet channel 12 along the third direction S3. Since the relative position of the two adjustment mechanisms 13 and one of the nozzle bodies 10 can remain stable during the whole process, the number of unstable parts involved in the adjustment process is relatively small, and it is easy to confirm the relative position of the first part 111, the second part 112 and the opening 102 of one of the nozzle bodies 10, and the operation difficulty of the operator is relatively low.

[0070] Preferably, the adjustment mechanism 13 includes a first mechanism body 1301 and a second mechanism body 1302 which are detachably connected to each other. The first mechanism bodies 1301 of the two adjustment mechanisms 13 are fixedly connected to the same nozzle body 10.

The first mechanism body 1301 and the second mechanism body 1302 can be disassembled and assembled separately so that the operator can inspect the interior of the adjustment mechanism 13 and replace parts.

[0071] Optionally, the first mechanism body 1301 may be fixedly connected to the nozzle body 10 by means including but not limited to welding, threaded connection, and gluing, or the first mechanism body 1301 may be integrally formed with the nozzle body 10 so that the first mechanism body 1301 and the nozzle body 10 are fixedly connected to form a whole.

[0072] Optionally, the first mechanism body 1301 and the second mechanism body 1302 may be detachably connected by means including but not limited to a threaded connection structure, a snap connection, and a magnetic connection.

[0073] Optionally, a side of the nozzle body 10 along the third direction S3 away from the liquid outlet channel 12 may also be provided with an air outlet hole 105 connected to the liquid storage tank 101, and the air outlet hole 105 is used to discharge the gas entering the liquid storage tank 101 to prevent the gas from entering the liquid outlet channel 12 and affecting the uniformity of the liquid spraying of the nozzle assembly 1.

[0074] like Fig.13 As shown, a spraying device 2 for manufacturing a display panel is also provided, comprising a liquid supply mechanism 20 and a nozzle assembly 1 as described in the above technical solution, the liquid supply mechanism 20 is connected to two liquid injection holes 100 of the nozzle assembly 1 (see Figure 4 ), since the spraying range of the nozzle assembly 1 can be adjusted so as to achieve liquid spraying only on the area of ​​the substrate 4 that needs to be produced, the spraying device 2 can reduce the waste of liquid, thereby reducing the production cost of the display panel, wherein, Fig.13 The dashed lines in the figure exemplarily show the edges of multiple display panels produced simultaneously on the same substrate 4.
