[0074] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.
[0075] This disclosure provides a dispensing method for a terminal device, such as... Figure 1 As shown, Figure 1 This is a flowchart illustrating a dispensing method for a terminal device according to an exemplary embodiment. Figure 1 The method includes:
[0076] Step S101: Obtain the position information of multiple potting holes within the mid-frame of the terminal device, wherein the multiple potting holes are interconnected.
[0077] Step S102: Based on the position information of the plurality of dispensing holes, control the dispensing head assembly in the dispensing device to inject the first adhesive and the second adhesive into the dispensing holes; wherein, the injection time of the second adhesive and the injection time of the first adhesive are spaced apart by a preset time.
[0078] The dispensing method shown in this embodiment is used to dispense adhesive into multiple potting holes in the dispensing area within the mid-frame of a terminal device. Here, the terminal device can be a smartphone, tablet, laptop, wearable device, or other terminal device that requires adhesive bonding or dispensing processes to bond related components. It should be noted that the bonding between related components of the terminal device can be between the mid-frame and the panel assembly, between the mid-frame and another component, or between other components.
[0079] In step S101, the position information of multiple potting holes on the mid-frame of the terminal device can be obtained by scanning the mid-frame.
[0080] It should be noted that the middle frame is used to support or fix the motherboard, battery and other internal components of the terminal device; and the middle frame is also used to connect with the panel assembly and cover plate of the terminal device to encapsulate and form the complete device.
[0081] The middle frame is disposed between the panel assembly and the cover plate, and the middle frame is provided with multiple glue-filling holes, which are interconnected; glue is applied to the multiple glue-filling holes to bond and fix the middle frame to the panel assembly and the cover plate.
[0082] The mid-frame of the terminal device to be glued can be placed on the operating table of the glue dispensing device. The glue dispensing device can then be used to obtain the position information of multiple glue-filling holes on the mid-frame.
[0083] In step S102, the movement path of the dispensing head assembly of the dispensing device is controlled according to the obtained position information of the plurality of dispensing holes, so as to align the dispensing head assembly with the dispensing holes; and after the dispensing head assembly is aligned with the dispensing holes, the first adhesive and the second adhesive are injected into the dispensing holes using the dispensing head assembly.
[0084] Here, the time interval between the injection time of the first colloid and the injection time of the second colloid is preset; the preset time interval can be set according to actual needs, for example, the preset time interval is 2 seconds.
[0085] In this embodiment of the disclosure, the first colloid and the second colloid are formed using the same colloid, or the first colloid and the second colloid are formed using the same manufacturing process. This embodiment of the disclosure does not limit this.
[0086] It is understandable that after the dispensing head assembly injects the first adhesive into the dispensing hole, a preset time is waited to allow the first adhesive to expel the gas in the dispensing hole before injecting the second adhesive into the dispensing hole.
[0087] It should be noted that in related technologies, when using a dispensing device to dispense glue into the potting holes of the middle frame, glue is usually dispensed only once. In actual production, due to limitations such as the venting performance of the potting holes and the flow properties of the glue, the dispensing effect of each potting hole in the middle frame cannot be guaranteed. If the glue cannot be fully filled into the potting holes, leaving residual gas inside, it will have a significant impact on the airtightness of the terminal equipment.
[0088] This embodiment of the invention injects a first colloid and a second colloid into the potting hole, with a preset time interval between the injection times of the first colloid and the second colloid. On the one hand, during the preset time interval, the first colloid is used to squeeze out some of the gas in the potting hole, and then the second colloid is injected. The second colloid is used to squeeze the first colloid, so that the first colloid can fully fill the space between the bottom and the inner wall of the potting hole, reducing the amount of residual gas in the potting hole and effectively improving the airtightness of the terminal device. On the other hand, by injecting the second colloid, the amount of colloid in the potting hole is increased, which increases the stability of the bonding between the middle frame and other components.
[0089] Optionally, controlling the dispensing head assembly within the dispensing device to inject a first adhesive and a second adhesive into the dispensing holes based on the position information of the plurality of dispensing holes includes:
[0090] Based on the location information of the plurality of glue-drinking holes, the glue-drinking path of the middle frame is determined;
[0091] Based on the dispensing sequence indicated by the dispensing path, the dispensing head assembly is controlled to sequentially inject the first adhesive into a plurality of the dispensing holes;
[0092] After the injection of the first adhesive is completed, the dispensing head assembly is controlled to inject the second adhesive into the plurality of dispensing holes in sequence according to the dispensing sequence indicated by the dispensing path.
[0093] In this embodiment of the disclosure, after obtaining the position information of the plurality of glue-drinking holes, the glue-drinking path of the middle frame can be determined according to the positional distribution of the plurality of glue-drinking holes on the middle frame.
[0094] It is understood that the dispensing path is a linear trajectory, and the linear trajectory covers all the potting holes within the middle frame. The dispensing path can also be a closed shape, such as a square, rectangle, or irregular shape. The dispensing path can be determined according to the distribution of multiple potting holes within the middle frame, and its specific shape and size are not limited in this embodiment.
[0095] In some embodiments, the position coordinates of multiple potting holes on the middle frame can be obtained; the distance information between any two potting holes can be determined according to the position coordinates of the multiple potting holes; the dispensing order of the multiple potting holes can be determined based on the distance information; and the dispensing path can be generated by connecting the position coordinates of the multiple potting holes according to the dispensing order of the multiple potting holes.
[0096] It is understood that the dispensing path is used at least to indicate the dispensing sequence of the multiple potting holes within the middle frame.
[0097] After determining the dispensing path of multiple potting holes within the middle frame, the potting hole to be dispensed is determined according to the dispensing sequence indicated by the dispensing path; based on the position information of the potting hole to be dispensed, the dispensing head assembly is controlled to move to align with the potting hole to be dispensed, and the first adhesive is injected into the potting hole to be dispensed; during the injection of the first adhesive, the next potting hole to be dispensed is determined.
[0098] After completing the injection of the first adhesive into the current dispensing hole, based on the position information of the next dispensing hole, the dispensing head assembly is controlled to move to align with the next dispensing hole and inject the first adhesive into the next dispensing hole; this process is repeated until the dispensing head assembly completes the injection of the first adhesive into multiple dispensing holes in the middle frame according to the dispensing sequence indicated by the dispensing path.
[0099] After the dispensing head assembly completes the injection of the first adhesive into the multiple dispensing holes in the middle frame, the dispensing head assembly is then controlled to inject the second adhesive into the multiple dispensing holes in sequence according to the dispensing sequence indicated by the dispensing path.
[0100] It is understood that the dispensing trajectory formed by the dispensing head assembly when injecting the first adhesive coincides with the dispensing trajectory formed by the dispensing head assembly when injecting the second adhesive.
[0101] In this embodiment of the disclosure, a first adhesive is injected into multiple potting holes sequentially according to the dispensing sequence indicated by the dispensing path; and after the first adhesive is injected into the multiple potting holes, a second adhesive is injected into the multiple potting holes sequentially again according to the dispensing sequence indicated by the dispensing path.
[0102] On the one hand, it can make full use of the waiting time required after the first glue is injected into the glue hole, and inject the first glue into the next glue hole, effectively shortening the glue dispensing time required for multiple glue holes in the middle frame and improving the glue dispensing efficiency of the middle frame.
[0103] On the other hand, it can ensure that there is a preset time interval between the injection time of the first colloid and the injection time of the second colloid in each dispensing hole; so that within the preset time interval, the first colloid is used to squeeze out some of the gas in the dispensing hole, and then the second colloid is injected. The second colloid is used to squeeze the first colloid, so that the first colloid can fully fill the bottom and inner wall of the dispensing hole, reduce the amount of residual gas in the dispensing hole, and effectively improve the airtightness of the terminal device.
[0104] Optionally, the dispensing head assembly includes: a dispensing needle;
[0105] The step of controlling the dispensing head assembly within the dispensing device to inject a first adhesive and a second adhesive into the dispensing holes based on the position information of the plurality of dispensing holes includes:
[0106] Based on the position information of the plurality of dispensing holes, the dispensing head assembly in the dispensing device is controlled to move toward the direction of the dispensing hole;
[0107] When the dispensing head assembly moves to a predetermined position, the dispensing needle of the dispensing head assembly is controlled to inject the first adhesive and the second adhesive into the dispensing hole.
[0108] In this embodiment of the disclosure, the dispensing head assembly includes: a dispensing needle;
[0109] The movement of the dispensing head assembly toward the direction of the dispensing hole may include: movement along a first direction, movement along a second direction, and / or movement along a third direction.
[0110] Here, the first direction is the projection direction of the dispensing head assembly toward the middle frame; the second direction and the third direction are both perpendicular to the first direction, and the second direction and the third direction are perpendicular. It can be understood that the first direction can be the Z-axis direction, the second direction can be the X-axis direction, and the third direction can be the Y-axis direction; or, the first direction can be the Z-axis direction, the second direction can be the Y-axis direction, and the third direction can be the X-axis direction; this embodiment does not limit the specific direction.
[0111] Based on the position information of the plurality of glue-filling holes on the middle frame, the movement of the glue-dispensing head assembly along the second direction and / or the third direction can be controlled so that the glue-dispensing head assembly is aligned with the glue-filling holes on the middle frame;
[0112] Here, the alignment of the dispensing head assembly with the glue filling hole is such that the projection of the dispensing head assembly toward the middle frame coincides with the glue filling hole;
[0113] After the dispensing head assembly is aligned with the filling hole, the dispensing head assembly is controlled to move along the first direction; when the dispensing head assembly moves to the predetermined position, the dispensing needle of the dispensing head assembly is controlled to inject the first adhesive and the second adhesive into the filling hole.
[0114] Here, the predetermined position can be set according to actual needs, as long as the dispensing needle is at least partially inserted into the dispensing hole when the dispensing head assembly is in the predetermined position.
[0115] For example, the predetermined position can be determined based on the average height difference between the dispensing head assembly and the plurality of dispensing holes when in the initial position, so as to ensure that when dispensing each dispensing hole in the terminal device is performed, the dispensing needle is inserted into the dispensing hole when the dispensing head assembly moves to the predetermined position.
[0116] Optionally, the dispensing head assembly includes: a limiting component;
[0117] When the dispensing head assembly moves to a predetermined position, controlling the dispensing needle of the dispensing head assembly to inject the first adhesive and the second adhesive into the dispensing hole includes:
[0118] When the limiting component of the dispensing head assembly abuts against the middle frame, the dispensing needle of the dispensing head assembly is controlled to inject the first adhesive and the second adhesive into the dispensing hole.
[0119] In this embodiment of the disclosure, the dispensing head assembly further includes: a limiting component;
[0120] It should be noted that during the injection of the first and second colloids, the depth to which the dispensing needle of the dispensing head assembly is inserted into the dispensing hole will affect the dispensing effect of the dispensing hole. It is understood that if the depth to which the dispensing needle is inserted into the dispensing hole when injecting the first colloid is different from the depth to which the dispensing needle is inserted into the dispensing hole when injecting the second colloid, the second colloid may not be able to effectively squeeze the first colloid, resulting in residual gas at the bottom of the dispensing hole or between the first and second colloids, thus leading to poor dispensing effect and poor airtightness of the terminal device.
[0121] To reduce the difference between the dispensing depth when the dispensing needle injects the first adhesive and the dispensing depth when the dispensing needle injects the second adhesive, this embodiment of the present disclosure may provide a limiting component in the dispensing head assembly. When the dispensing head assembly is aligned with the dispensing hole, the dispensing head assembly is controlled to move along a first direction, and when the limiting component abuts against the middle frame, the dispensing needle of the dispensing head assembly is controlled to inject the first adhesive and the second adhesive into the dispensing hole.
[0122] It is understood that when the limiting component abuts against the middle frame, the depth to which the dispensing needle inserts into the glue-filling hole is determined by the distance between the tip of the dispensing needle and the limiting component. Since the distance between the tip of the dispensing needle and the limiting component is a fixed value, during the dispensing process, the dispensing head assembly can be controlled to move towards the glue-filling hole until the limiting component of the dispensing head assembly abuts against the middle frame. After the limiting component abuts against the middle frame, glue is dispensed into the glue-filling hole, thereby ensuring that the depth to which the dispensing needle inserts into the glue-filling hole is the same each time glue is dispensed.
[0123] In this embodiment, after the limiting component of the dispensing head assembly abuts against the middle frame, the dispensing needle of the dispensing head assembly is controlled to inject a first adhesive and a second adhesive into the dispensing hole. This ensures that the dispensing depth when the dispensing needle injects the first adhesive is the same as the dispensing depth when the dispensing needle injects the second adhesive. The second adhesive can effectively compress the first adhesive, allowing the first adhesive to fully fill the space between the bottom and the inner wall of the dispensing hole, reducing the amount of residual gas in the dispensing hole and effectively improving the airtightness of the terminal device.
[0124] Optionally, the dispensing head assembly includes: a ranging module;
[0125] The method includes:
[0126] When the limiting component of the dispensing head assembly abuts against the middle frame, the ranging module is used to detect the first dispensing depth of the dispensing needle of the dispensing head assembly inserted into the dispensing hole;
[0127] Based on the first dispensing depth, determine the maximum amount of movement of the dispensing head assembly along the first direction;
[0128] The control of the dispensing head assembly within the dispensing device to inject the first and second adhesives into the dispensing hole includes:
[0129] The dispensing head assembly is controlled to move toward the dispensing hole and inject the first adhesive and the second adhesive into the dispensing hole; wherein the amount of movement of the dispensing head assembly in the first direction is less than or equal to the maximum amount of movement.
[0130] In this embodiment of the disclosure, the dispensing head assembly includes: a ranging module;
[0131] When the dispensing head assembly moves toward the direction of the dispensing hole and the limiting component of the dispensing head assembly abuts against the middle frame, the first dispensing depth of the dispensing needle inserted into the dispensing hole is detected by the ranging module.
[0132] Here, the first dispensing depth is the maximum dispensing depth into which the dispensing needle is inserted into the dispensing hole; it can be understood that, due to the limiting effect of the limiting component, when the limiting component abuts against the middle frame, the dispensing head component is restricted from continuing to move towards the direction closer to the dispensing hole; at this time, the dispensing depth into the dispensing hole is the maximum dispensing depth into which the dispensing needle can be inserted.
[0133] It should be noted that, since the middle frame is located between the panel assembly and the cover plate assembly, when dispensing glue into the potting hole on the middle frame, if the dispensing needle is inserted too deeply into the potting hole, the dispensing needle may easily poke the panel assembly of the terminal device, thereby damaging the panel assembly and causing display black spots on the panel assembly of the terminal device.
[0134] It is understood that the maximum allowable depth of each potting hole on the middle frame can be determined by the distance between the middle frame and the panel assembly. In order to reduce the damage to the panel assembly by the dispensing needle during the dispensing process, the relative position between the dispensing needle and the limiting component can be adjusted so that when the limiting component abuts against the middle frame, the first potting depth of the dispensing needle inserted into the potting hole is less than or equal to the maximum allowable depth of the potting hole.
[0135] After determining the first dispensing depth, the distance between the dispensing needle and the middle frame can be detected using a ranging component when the dispensing head assembly is at its initial height position. Based on the distance between the dispensing needle and the middle frame and the first dispensing depth, the amount of movement required for the dispensing head assembly to move from the initial height position to the point where the limiting component abuts against the middle frame can be determined. It can be understood that this amount of movement is the maximum amount of movement of the dispensing head assembly along the first direction.
[0136] Since the first direction is the projection direction of the dispensing head assembly toward the middle frame; and during the dispensing process, the movement of the dispensing head assembly toward the direction closer to the dispensing hole may include: movement along the first direction, movement along the second direction, and / or movement along a third direction. Therefore, the amount of movement of the dispensing head assembly may include: the amount of movement along the first direction, the amount of movement along the second direction, and / or the amount of movement along a third direction.
[0137] When the dispensing head assembly moves toward the direction close to the dispensing hole, the movement of the dispensing head assembly in the first direction is controlled according to the maximum movement of the dispensing head assembly in the first direction, so that the movement of the dispensing head assembly in the first direction is less than or equal to the maximum movement, thereby reducing the situation where the limiting component and the middle frame are excessively abutted, and reducing the damage of the limiting component to the middle frame and the components fixed in the middle frame.
[0138] Optionally, the method includes:
[0139] When the dispensing needle of the dispensing head assembly injects the first adhesive into the filling hole, the ranging module detects the second filling depth of the dispensing needle inserted into the filling hole; the second filling depth is less than or equal to the first filling depth.
[0140] The control of the dispensing head assembly to inject the second adhesive into the plurality of dispensing holes includes:
[0141] Based on the second dispensing depth corresponding to the dispensing hole, the target height position corresponding to the dispensing hole is determined; wherein, when the dispensing head assembly is at the target height position, the third dispensing depth of the dispensing needle inserted into the dispensing hole is the same as the second dispensing depth;
[0142] The dispensing head assembly is controlled to move to the target height position corresponding to the dispensing hole, and the second adhesive is injected into the dispensing hole using the dispensing needle.
[0143] In this embodiment of the disclosure, when the dispensing needle injects the first adhesive into the dispensing hole, the ranging module in the dispensing head assembly is used to detect the second dispensing depth of the dispensing needle inserted into the dispensing hole.
[0144] It is understood that, since the dispensing head assembly is equipped with a limiting component, the second dispensing depth of the dispensing needle inserted into the dispensing hole is less than or equal to the maximum dispensing depth (i.e., the first dispensing depth) that the dispensing needle can insert into the dispensing hole.
[0145] To reduce the difference between the dispensing depth when injecting the first adhesive and the dispensing depth when injecting the second adhesive, the target height position corresponding to the dispensing hole can be determined based on the second dispensing depth before injecting the second adhesive into the dispensing hole.
[0146] It is understood that when the dispensing head assembly is at the target height position, the third dispensing depth into the dispensing hole is the same as the second dispensing depth.
[0147] Before injecting the second adhesive into the dispensing hole using the dispensing needle, the target height position of the dispensing needle can be determined based on the second dispensing depth corresponding to the dispensing hole.
[0148] During the process of injecting the second adhesive into the dispensing hole, the dispensing head assembly is controlled to move to the target height position; after the dispensing head assembly is at the target height position, the second adhesive is injected into the dispensing hole using the dispensing needle.
[0149] This embodiment of the disclosure uses a ranging module to detect the second dispensing depth when the dispensing needle injects the first adhesive into the dispensing hole, and determines the target height position of the dispensing head assembly corresponding to the second dispensing depth. During the injection of the second adhesive, the dispensing head assembly is controlled to move to the target height position before the second adhesive is injected into the dispensing hole, so that the dispensing depth when the dispensing needle injects the first adhesive is the same as the dispensing depth when the dispensing needle injects the second adhesive. This allows the second adhesive to effectively compress the first adhesive, ensuring that the first adhesive fully fills the space between the bottom and the inner wall of the dispensing hole, reducing the amount of residual gas in the dispensing hole and effectively improving the airtightness of the terminal device. It also reduces the possibility of excessive contact between the limiting component and the middle frame, reducing damage to the middle frame and the components fixed inside the middle frame caused by the limiting component.
[0150] Optionally, controlling the dispensing head assembly within the dispensing device to inject a first adhesive and a second adhesive into the dispensing holes based on the position information of the plurality of dispensing holes includes:
[0151] Based on the position information of the plurality of dispensing holes, the dispensing head assembly is controlled to inject the first adhesive and the second adhesive into the first dispensing hole to be dispensed;
[0152] Negative pressure adsorption is applied to the second dispensing hole and / or the exhaust channel of the terminal device; wherein, the second dispensing hole is a dispensing hole in which the first colloid and / or the second colloid has not been injected.
[0153] In this embodiment, a first and a second dispensing hole are identified from among a plurality of dispensing holes. Based on the position information of the first dispensing hole, the movement path of the dispensing head assembly of the dispensing device is determined to facilitate alignment between the dispensing head assembly and the dispensing hole. After the dispensing head assembly is aligned with the dispensing hole, a first and a second colloid are injected into the first dispensing hole using the dispensing head assembly. A negative pressure device is used to perform negative pressure adsorption on the second dispensing hole and / or the exhaust channel.
[0154] Here, the terminal device is provided with an exhaust channel, which is interconnected with the plurality of glue-filling holes.
[0155] The negative pressure device has a negative pressure tube, which can be inserted into the second glue-filling hole and / or the exhaust channel. The negative pressure tube is used to draw out the residual gas in the first glue-filling hole, so that the first glue and the second glue can fully fill the first glue-filling hole, thereby improving the airtightness of the terminal device.
[0156] This disclosure provides a dispensing device, such as... Figure 2 As shown, Figure 2 This is a schematic diagram of a dispensing apparatus according to an exemplary embodiment; the dispensing apparatus 10 includes:
[0157] 11 plastic bottles;
[0158] Dispensing head assembly 12 includes:
[0159] The dispensing needle 121 is connected to the glue bottle 11 and is used to inject the first glue and the second glue into multiple glue filling holes in the middle frame of the terminal device.
[0160] The limiting component 122 is fixedly connected to the dispensing needle 121;
[0161] The limiting component 122 cooperates with the middle frame to limit the dispensing depth of the dispensing needle 121 into the dispensing hole to be less than or equal to the maximum depth that the dispensing hole can tolerate.
[0162] The dispensing device shown in this embodiment can be used to dispense adhesive into multiple dispensing holes in the dispensing area within the middle frame of a terminal device; here, the terminal device can be a smartphone, tablet computer, laptop computer, wearable device, or other terminal device that requires adhesive bonding or dispensing process to bond related components.
[0163] In this embodiment of the disclosure, the dispensing device includes: a glue bottle and a dispensing head assembly;
[0164] The bottle opening is connected to the dispensing head assembly, through which the glue from the bottle is dispensed.
[0165] In some embodiments, the dispensing apparatus includes: a receiving component;
[0166] The receiving assembly has a receiving cavity for placing the glue bottle;
[0167] The receiving component has a dispensing port at one end facing the dispensing head assembly, and the glue bottle is connected to the dispensing head assembly through the dispensing port;
[0168] An airbag is provided inside the accommodating component;
[0169] The adhesive bottle is squeezed by the expansion of the air bladder, forcing the adhesive inside the bottle into the dispensing head assembly.
[0170] In this embodiment of the disclosure, the dispensing head assembly includes: a dispensing needle;
[0171] The dispensing needle is connected to the glue bottle through the dispensing port of the glue bottle, and the dispensing needle can be inserted into the glue filling hole to inject the first glue and the second glue into the glue filling hole.
[0172] Here, the time interval between the injection time of the first colloid and the injection time of the second colloid is preset.
[0173] It should be noted that the first and second colloids are formed using the same colloid (i.e., the colloid stored in the glue bottle). After the dispensing needle of the dispensing head assembly injects the first colloid into the glue filling hole, a preset time is waited to allow the first colloid to expel the gas in the glue filling hole before the second colloid is injected into the glue filling hole.
[0174] Understandably, by injecting a first colloid and a second colloid into the potting hole, with a preset time interval between the injection of the first colloid and the injection of the second colloid, on the one hand, during the preset time interval, the first colloid is used to squeeze out some of the gas in the potting hole, and then the second colloid is injected, using the second colloid to squeeze the first colloid, so that the first colloid can fully fill the space between the bottom and the inner wall of the potting hole, reducing the amount of residual gas in the potting hole and effectively improving the airtightness of the terminal device; on the other hand, by injecting the second colloid, the amount of colloid in the potting hole is increased, increasing the stability of the bonding between the middle frame and other components.
[0175] The dispensing head assembly includes: a limiting component;
[0176] The limiting component can be fixedly mounted on the dispensing needle; it is understood that the limiting component can be formed with a through hole through the limiting component, so that the dispensing needle can be inserted into the limiting component through the through hole.
[0177] The length of the portion of the dispensing needle that extends beyond the limiting component is the maximum dispensing depth to which the dispensing needle can be inserted into the dispensing hole.
[0178] It should be noted that the depth to which the dispensing needle is inserted into the dispensing hole will affect the dispensing effect of the dispensing hole. It is understood that if the dispensing needle is inserted into the dispensing hole to a greater depth, the dispensing needle may easily poke the panel component of the terminal device, thereby damaging the panel component and causing black spots on the display of the terminal device's panel component.
[0179] To reduce damage to the panel components of the terminal device when using a dispensing device, embodiments of this disclosure can adjust the length of the portion of the dispensing needle that extends beyond the limiting component, such that when the limiting component abuts against the middle frame, the dispensing depth (i.e., the maximum dispensing depth) of the dispensing needle inserted into the dispensing hole is less than or equal to the maximum depth that the dispensing hole can tolerate.
[0180] This embodiment of the invention provides a limiting component on the dispensing needle. During the dispensing process using the dispensing needle to dispense glue into the glue hole, the limiting component abuts against the mid-frame assembly, limiting the maximum glue depth into which the dispensing needle inserts into the glue hole. This ensures that the maximum glue depth into which the dispensing needle inserts into the glue hole is less than or equal to the maximum allowable depth of the glue hole, thereby reducing damage to the panel assembly of the terminal device caused by the dispensing needle.
[0181] It should be noted that the dispensing depth when the dispensing needle injects the first adhesive into the dispensing hole and the dispensing depth when injecting the second adhesive can also be limited by the limiting component and the middle frame, so that the dispensing depth when injecting the first adhesive and the dispensing depth when injecting the second adhesive are the same, thereby reducing the difference between the dispensing depth when the dispensing needle injects the first adhesive and the dispensing depth when injecting the second adhesive.
[0182] It is understandable that if the depth to which the dispensing needle is inserted into the dispensing hole when injecting the first colloid is different from the depth to which the dispensing needle is inserted into the dispensing hole when injecting the second colloid, the second colloid may not be able to effectively squeeze the first colloid, resulting in residual gas at the bottom of the dispensing hole or between the first and second colloids, thus leading to poor dispensing effect and poor airtightness of the terminal device.
[0183] When the limiting component abuts against the middle frame, the dispensing depth of the dispensing needle inserted into the dispensing hole is determined by the distance between the tip of the dispensing needle and the limiting component; and the distance between the tip of the dispensing needle and the limiting component is a fixed value; therefore, during the dispensing process, after the limiting component of the dispensing head assembly abuts against the middle frame, the dispensing needle can be used to inject the first adhesive and the second adhesive into the dispensing hole, so that the dispensing depth when injecting the first adhesive and the dispensing depth when injecting the second adhesive are the same, and the second adhesive can be used to effectively squeeze the first adhesive, so that the first adhesive can fully fill the bottom and inner wall of the dispensing hole, reduce the amount of residual gas in the dispensing hole, and effectively improve the airtightness of the terminal device.
[0184] In some embodiments, the dispensing device includes:
[0185] An operating table for placing the terminal device;
[0186] A drive component, connected to the dispensing head assembly, is used to drive the dispensing head assembly to move.
[0187] It should be noted that the drive assembly is provided with a fixing seat for fixing the glue bottle and connecting it to the dispensing head assembly through the glue bottle;
[0188] The dispensing head assembly is driven by a drive component to move along a second direction and / or a third direction, so that the dispensing head assembly is aligned with the glue-filling hole in the middle frame of the terminal device on the operating table; after the dispensing head assembly is aligned with the glue-filling hole, the dispensing head assembly is driven by a drive component to move along a first direction, so that the dispensing needle of the dispensing head assembly is inserted into the glue-filling hole.
[0189] Optionally, such as Figure 3 As shown, Figure 3 This is a schematic diagram illustrating the structure of a dispensing head assembly according to an exemplary embodiment. The limiting component 122 includes:
[0190] A sleeve body 1221, wherein an accommodating cavity is formed inside the sleeve body 1221 for partially accommodating the dispensing needle 121;
[0191] The sleeve body 1221 is provided with a limiting part 1221a at the first end near the glue-filling hole; wherein, the area of the contact surface between the limiting part 1221a and the middle frame is larger than the opening area of the glue-filling hole.
[0192] In this embodiment of the disclosure, the limiting component includes: a sleeve body;
[0193] A receiving cavity is formed inside the sleeve body, a part of the dispensing needle is received in the receiving cavity, and another part of the dispensing needle is located outside the sleeve body; it can be understood that the length of the part of the dispensing needle located outside the sleeve body can be determined by the maximum depth that the dispensing hole can allow.
[0194] The sleeve body is provided with a limiting part at the first end near the glue-filling hole; it can be understood that the sleeve body abuts against the middle frame through the limiting part.
[0195] In order to limit the depth of dispensing needle insertion into the dispensing hole by using the sleeve body, in this embodiment of the present disclosure, the area of the contact surface between the limiting part and the middle frame is larger than the opening area of the dispensing hole.
[0196] Because the contact area between the limiting part and the middle frame is larger than the opening area of the glue-filling hole, when the sleeve body abuts against the middle frame, the limiting part of the sleeve body cannot be inserted into the glue-filling hole, thereby limiting the glue-filling depth of the glue-filling needle inserted into the glue-filling hole.
[0197] Optionally, the dispensing needle includes a needle tip and a syringe tube, and the needle tip is connected to the output end of the syringe tube;
[0198] The first end of the sleeve body is provided with a through hole penetrating the limiting part, for the needle to extend out of the sleeve body through the through hole;
[0199] The second end of the sleeve body is provided with an installation opening that communicates with the receiving cavity, for the needle to be installed into the receiving cavity through the installation opening.
[0200] In this embodiment of the disclosure, the dispensing needle includes: a needle tip and a syringe tube;
[0201] The syringe has an input end and an output end. The input end of the syringe is connected to the dispensing port of the glue bottle, and the output end of the syringe is connected to the needle tip, so that the glue in the glue bottle flows through the syringe to the needle tip and is output from the needle tip.
[0202] The first end of the sleeve body is provided with a through hole, which penetrates the limiting part. The tip of the dispensing needle passes through the through hole and extends out of the sleeve body.
[0203] The second end of the sleeve body is provided with an installation opening, which communicates with the receiving cavity inside the sleeve body. The needle tube of the dispensing needle is installed in the receiving cavity of the sleeve body through the installation opening.
[0204] In some embodiments, a mounting portion is formed at the mounting opening of the sleeve body, the mounting portion being used for mounting the glue bottle onto the sleeve body.
[0205] In this embodiment of the disclosure, the glue bottle can be mounted to the mounting opening of the sleeve body via a mounting part on the sleeve body; it is understood that the dispensing port of the glue bottle is mounted at the mounting opening and is connected to the input end of the needle.
[0206] In this embodiment, the glue bottle is mounted on the sleeve body through the mounting portion formed at the mounting opening of the sleeve body, thereby connecting the glue bottle and the dispensing head assembly.
[0207] Optionally, the dispensing device includes:
[0208] A ranging module is disposed on the dispensing head assembly and is used to detect the dispensing depth of the dispensing needle of the dispensing head assembly inserted into the dispensing hole.
[0209] In this embodiment of the disclosure, the dispensing device includes: a ranging module;
[0210] Here, the ranging module may be a laser ranging module or a radar ranging module, and this embodiment does not limit the specific type of ranging module.
[0211] The ranging module can be installed on the dispensing head assembly to detect the dispensing depth of the dispensing needle of the dispensing head assembly inserted into the dispensing hole.
[0212] It should be noted that the maximum allowable depth of each glue-filling hole on the middle frame can be determined by the distance between the middle frame and the panel assembly. In order to reduce the damage to the panel assembly by the glue-filling needle during the glue-filling process, a limiting component is provided in the glue-filling head assembly, so that when the limiting component abuts against the middle frame, the glue-filling depth of the glue-filling needle inserted into the glue-filling hole is less than or equal to the maximum allowable depth of the glue-filling hole.
[0213] However, considering that there are many components on the middle frame, the limiting component may cause damage to the middle frame and the components fixed on the middle frame when it comes into contact with the middle frame. Therefore, in this embodiment, a ranging module can be set in the dispensing device. When dispensing the middle frame, the ranging module is used to detect the first dispensing depth of the dispensing needle inserted into the dispensing hole when the limiting component comes into contact with the middle frame.
[0214] This allows the dispensing device to determine the maximum movement of the dispensing head assembly along the first direction based on the first dispensing depth; and to control the movement of the dispensing head assembly in the first direction based on the maximum movement of the dispensing head assembly in the first direction, so that the movement of the dispensing head assembly in the first direction is less than or equal to the maximum movement, thereby reducing the situation where the limiting component and the middle frame excessively abut against each other, and reducing the damage of the limiting component to the middle frame and the components fixed inside the middle frame.
[0215] In addition, when the dispensing needle injects the first adhesive into the filling hole, a ranging module is used to detect the second filling depth of the dispensing needle into the filling hole; so that the dispensing device can determine the target height position corresponding to the filling hole based on the second filling depth; during the process of injecting the second adhesive into the filling hole, the dispensing head assembly is controlled to move to the target height position; after the dispensing head assembly is at the target height position, the dispensing needle is used to inject the second adhesive into the filling hole, so that the filling depth when the dispensing needle injects the first adhesive is the same as the filling depth when the dispensing needle injects the second adhesive.
[0216] This disclosure provides a terminal device, such as... Figure 4 As shown, Figure 4 This is a schematic diagram illustrating the structure of a mid-frame (partial) of a terminal device according to an exemplary embodiment. The terminal device includes:
[0217] Mid-frame 20 includes:
[0218] Adhesive backing area 21;
[0219] The glue dispensing area 22 is located on the outer periphery of the adhesive backing area 21, and an exhaust channel 23 is provided between the glue dispensing area 22 and the adhesive backing area 21.
[0220] Multiple dispensing holes 221 are located within the dispensing area 22, and the multiple dispensing holes 221 are connected to the venting channel 23;
[0221] When the dispensing head assembly of the dispensing device injects the first and second adhesives into the plurality of dispensing holes, the gas in the plurality of dispensing holes 221 is compressed by the first and second adhesives and discharged from the exhaust channel 23.
[0222] The terminal devices shown in the embodiments of this disclosure can be smartphones, tablets, laptops, wearable devices, and other terminal devices that require adhesive bonding or dispensing processes to bond related components.
[0223] The terminal device includes: a mid-frame;
[0224] It should be noted that the middle frame is used to support or fix the internal components of the terminal device, such as the motherboard and battery.
[0225] The terminal device further includes: a panel assembly and a cover plate;
[0226] The mid-frame is also used to connect with the panel assembly and cover plate of the terminal device for encapsulation to form a complete device.
[0227] It is understood that the middle frame is disposed between the panel assembly and the cover plate, and the middle frame is provided with multiple glue-dip holes. Glue is applied to the multiple glue-dip holes to bond and fix the middle frame to the panel assembly and the cover plate.
[0228] The middle frame includes: an adhesive backing area and an adhesive dispensing area;
[0229] The adhesive backing area can be used to apply adhesive backing, and the dispensing area is provided with multiple dispensing holes.
[0230] The dispensing area is located on the outer periphery of the adhesive backing area.
[0231] It should be noted that the adhesive dispensing area is usually close to the edge area of the middle frame; the adhesive backing area is located inside the adhesive dispensing area, away from the edge area of the middle frame, that is, the adhesive dispensing area surrounds the adhesive backing area.
[0232] To facilitate venting of the dispensing holes during the dispensing process, an venting channel can be provided between the dispensing area and the adhesive backing area, and the venting channel is connected to multiple dispensing holes within the dispensing area.
[0233] When the dispensing head assembly injects the first and second adhesives into the dispensing hole, the gas inside the dispensing hole is compressed by the first and second adhesives and discharged from the connected exhaust channel, reducing the amount of residual gas in the dispensing hole and improving the airtightness of the terminal device.
[0234] In actual production, due to limitations such as the venting performance of the glue-filling holes and the flow properties of the glue, it is impossible to guarantee the glue-filling effect of each glue-filling hole in the middle frame. If the glue cannot be filled properly in the glue-filling hole, leaving residual gas in the glue-filling hole, it will have a significant impact on the airtightness of the terminal equipment.
[0235] By injecting a first adhesive and a second adhesive into the glue-filling hole, with a preset time interval between the injection times of the first and second adhesives, on the one hand, during the preset time interval, the first adhesive is used to compress some of the gas in the glue-filling hole, causing some of the gas to be discharged from the exhaust channel. Then, the second adhesive is injected, and the second adhesive is used to compress the first adhesive, so that the first adhesive can fully fill the space between the bottom and the inner wall of the glue-filling hole, reducing the amount of residual gas in the glue-filling hole and effectively improving the airtightness of the terminal device. On the other hand, by injecting the second adhesive, the amount of adhesive in the glue-filling hole is increased, which increases the stability of the bonding between the middle frame and other components.
[0236] Optionally, the venting channel is the venting gap formed between the dispensing area and the adhesive backing area.
[0237] In this embodiment of the disclosure, an venting gap can be reserved directly between the dispensing area and the adhesive backing area. The venting gap is connected to multiple potting holes in the dispensing area. During the injection of the first and second colloids into the potting holes, the residual gas in the potting holes is discharged using the venting gap.
[0238] In some embodiments, the gap width of the exhaust gap is 0.15 mm.
[0239] This embodiment of the invention reserves an venting gap between the dispensing area and the adhesive backing area. On the one hand, when the first and second adhesives are injected into the dispensing hole, the gas in the dispensing hole is discharged through the venting gap, reducing the amount of residual gas in the dispensing hole and effectively improving the airtightness of the terminal device. On the other hand, the venting gap reserved between the dispensing area and the adhesive backing area is directly used as the venting channel of the dispensing hole, reducing the impact of the venting channel on the components set on the middle frame and reducing the impact of the venting channel on the thickness of the terminal device.
[0240] This disclosure also provides the following embodiments:
[0241] Figure 5This is a flowchart illustrating a dispensing method for a terminal device according to an exemplary embodiment. Figure 2 The method includes:
[0242] Step S201: Obtain the position information of multiple potting holes within the mid-frame of the terminal device; determine the dispensing path of the mid-frame based on the position information of the multiple potting holes;
[0243] In this example, the terminal device to be dispensed can be placed in the positioning fixture of the dispensing device's operating table, and the start button of the dispensing device can be pressed to initiate dispensing. Figure 6-7 As shown, Figure 6 This is a schematic diagram of the operating table of a dispensing device according to an exemplary embodiment; Figure 7 This is a schematic diagram of the operation panel of a dispensing device according to an exemplary embodiment.
[0244] The dispensing device scans the position information of multiple glue-filling holes within the mid-frame of the terminal equipment, and determines the dispensing path of the mid-frame based on the position information of the multiple glue-filling holes. For example... Figure 8 As shown, Figure 8 This is a schematic diagram illustrating a plurality of glue-filling holes within a middle frame according to an exemplary embodiment. The middle frame is provided with a first glue-filling hole 221a and a second glue-filling hole 221b; the glue-filling path of the middle frame is from the first glue-filling hole 221a to the second glue-filling hole 221b.
[0245] Step S202: Based on the dispensing sequence indicated by the dispensing path, control the dispensing head assembly of the dispensing device to sequentially inject the first adhesive into the plurality of dispensing holes;
[0246] In this example, according to the dispensing sequence indicated by the dispensing path, the dispensing head assembly is controlled to move sequentially to align with the plurality of potting holes, and moves along a first direction so that the dispensing needle is inserted into the potting hole. Figure 9 As shown, Figure 9 This is a schematic diagram of a dispensing device according to an exemplary embodiment.
[0247] The ranging module in the dispensing device can be used to detect the second dispensing depth of the dispensing needle inserted into the dispensing hole when the first adhesive is injected; the second dispensing depth is used to determine the target height position of the dispensing head assembly when the second adhesive is injected.
[0248] In some embodiments, in order to reduce damage to the display screen of the terminal device during the dispensing process, a limiting sleeve can be provided on the dispensing needle. The limiting sleeve restricts the dispensing needle from being inserted into the dispensing hole to a depth less than or equal to the maximum depth that the dispensing hole can tolerate.
[0249] Step S203: After the injection of the first adhesive is completed, the dispensing head assembly is controlled to inject the second adhesive into the plurality of dispensing holes based on the dispensing sequence indicated by the dispensing path.
[0250] In this example, after the first adhesive is injected into the multiple potting holes on the center frame, the dispensing head assembly is controlled to move sequentially to align with the multiple potting holes according to the dispensing sequence indicated by the dispensing path, and then moves along the first direction to inject the second adhesive into the multiple potting holes.
[0251] It is understood that there is a preset time interval between the injection time of the first colloid and the injection time of the second colloid.
[0252] It should be noted that a cyclical dispensing method can be used for multiple glue holes within the middle frame, such as... Figure 8 As shown, the middle frame has two glue-drinking holes (first glue-drinking hole 221a and second glue-drinking hole 221b), and the glue-drinking sequence is: 221a-221b-221a-221b. That is, each glue-drinking hole in the middle frame is glued twice.
[0253] When injecting the second adhesive into the dispensing hole, the dispensing head assembly can be controlled to move to a target height position determined by the second dispensing depth; and when the dispensing head assembly is at the target height position, the second adhesive is injected into the dispensing hole using the dispensing needle.
[0254] Understandably, during the two dispensing processes into the dispensing hole, the dispensing needle maintains the same dispensing depth within the hole, thereby effectively expelling residual gas and ensuring that the adhesive fills the hole, thus guaranteeing good airtightness of the terminal equipment.
[0255] like Figure 10 As shown, Figure 10 This is a schematic flowchart illustrating a dispensing method according to an exemplary embodiment. After injecting the second adhesive into multiple dispensing holes, the dispensing terminal device is removed. The dispensing effect of the terminal device can be visually inspected. Once it is determined that the dispensing effect of the terminal device meets the requirements, the terminal device is moved to the next workstation for subsequent processing. Figure 11-12 As shown, Figure 11 This is a schematic diagram illustrating the dispensing effect of a dispensing device displaying a dispensing orifice according to an exemplary embodiment; Figure 12 This is a comparative schematic diagram showing the dispensing of adhesive into a potting hole before and after, according to an exemplary embodiment.
