Description

Technical Field

[0001] This invention relates to the field of high-viscosity colloid filling technology, and more particularly to a high-viscosity colloid filling device and method. Background Technology

[0002] In various electronic components of pure electric and hybrid vehicles, such as motors, solenoid valves, and controllers, a process of injecting adhesive into the flow channels within the cavity is required. This is done by injecting a high-viscosity adhesive into the cavity to provide insulation, waterproofing, and aesthetics. Specifically, the high-viscosity adhesive refers to a viscous adhesive with a viscosity greater than 50,000 cP.

[0003] In current dispensing processes, a vacuum environment combined with gravity dispensing is commonly used. However, this method is prone to the following two problems: 1) It is difficult for the gas originally dissolved in the high-viscosity colloid to escape, resulting in a high gas content in the high-viscosity colloid. The solidification of gas in the high-viscosity colloid will affect the quality of electronic components such as motors, solenoid valves, and controllers, thereby affecting the performance of these components; 2) When the flow channels inside the cavity are complex and tortuous, it is difficult for the high-viscosity colloid to fill the various bends and turns within the flow channels, thus affecting the full filling and uniformity of the high-viscosity colloid in the complex and tortuous flow channels. Summary of the Invention

[0004] The purpose of this invention is to provide a high-viscosity colloid filling device and method, which can vibrate and expel the gas originally dissolved in the high-viscosity colloid, and can improve the full filling rate and filling uniformity of the high-viscosity colloid in the inner cavity. Moreover, the colloid filling is simple, convenient and low-cost.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0008] A vacuum pump is mounted on the sealing fixture and is used to evacuate the inner cavity of the part to be injected with adhesive so that the vacuum level of the inner cavity is the filling vacuum level.

[0009] A vibrating element, which is slidably connected to the first inner wall of the glue injection space along the Z-axis and can stop at any position;

[0010] The dispensing tube has its inlet end connected to the vibrating element and its outlet end extending downward along the Z-axis into the inner cavity. The vibrating element is used to drive the dispensing tube to vibrate synchronously, so that the high-viscosity colloid in the dispensing tube is vibrated and injected into the inner cavity.

[0011] As an optional solution, the outlet end of the dispensing tube is positioned close to the bottom surface of the inner cavity.

[0012] As an optional solution, the sealing fixture includes:

[0013] The lower fixture is used to position the part to be injected with adhesive on the lower fixture.

[0014] An upper fixture is slidably connected to the second inner wall of the glue injection space along the Z-axis, allowing the upper fixture to move along the Z-axis and stop at any position to seal against or move away from the lower fixture. The part to be glued is confined within the sealed space formed by the sealing fit between the upper and lower fixtures. The outlet end of the glue injection tube passes through the upper fixture downward along the Z-axis and extends into the inner cavity.

[0015] The first sealing ring is provided on the top surface of the lower fixture, and the upper fixture can fit and abut against the first sealing ring so that the upper fixture and the lower fixture are sealed and fitted together.

[0016] As an optional solution, the top surface of the lower fixture is recessed with a positioning groove, and the part to be injected is limited and engaged in the positioning groove.

[0017] As an optional solution, a first guide block is connected to one outer side of the upper fixture, and a first guide rail extending along the Z-axis is provided on the second inner sidewall of the glue injection space, and the first guide block can slide along the Z-axis on the first guide rail.

[0018] As an optional solution, the upper fixture is threaded with a connector, the first interface of the connector is sealed downward along the Z-axis through the upper fixture to extend into the inner cavity, and the length of the first interface extending into the inner cavity can be adjusted by turning the connector, and the second interface of the connector is connected to the vacuum pump through a first hose.

[0019] As an optional solution, the high-viscosity colloid filling device further includes:

[0020] A glue injection pump is provided, and a second hose is connected between the glue injection pump and the glue injection tube. The glue injection pump is used to power pump high-viscosity glue into the glue injection tube.

[0021] The second sealing ring is installed inside the upper fixture, and the glue injection tube slides along the Z-axis and abuts against the second sealing ring.

[0022] As an optional solution, the vibrating element is an ultrasonic vibration generator.

[0023] As an optional solution, a second guide block is connected to one outer side of the vibrating element, and a second guide rail extending along the Z-axis is provided on the first inner sidewall of the glue injection space. The second guide block can slide along the Z-axis on the second guide rail to drive the glue injection tube to move into or out of the inner cavity along the Z-axis.

[0024] A high-viscosity colloid filling method, wherein the high-viscosity colloid filling method is based on the high-viscosity colloid filling device described above, which fills the inner cavity of the part to be injected with colloid, and the high-viscosity colloid filling method includes the following steps:

[0025] S1: Position the part to be injected into the sealing fixture and use the vacuum pump to evacuate the inner cavity until the vacuum level of the inner cavity is the filling vacuum level; then extend the outlet end of the injection tube downward along the Z-axis into the inner cavity;

[0026] S2: Inject high-viscosity colloid into the inner cavity through the dispensing tube; simultaneously, vibrate the vibrating element to drive the dispensing tube to vibrate synchronously, so that the high-viscosity colloid in the dispensing tube flows and fills the inner cavity.

[0027] S3: When a preset amount of high-viscosity colloid is injected into the inner cavity, the injection is stopped; and the vibrating element continues to vibrate to drive the dispensing tube to vibrate synchronously for a preset time, after which the vibrating element stops vibrating;

[0028] S4: The vibrating element drives the glue injection tube to rise upward along the Z-axis from the inner cavity at a lifting rate. At the same time, the glue injection tube injects high-viscosity glue into the inner cavity at a glue injection rate to fill the gap space after the glue injection tube is lifted and withdrawn from the inner cavity. The vibrating element vibrates to drive the glue injection tube to vibrate synchronously. The lifting rate matches the glue injection rate.

[0029] The beneficial effects of this invention are:

[0030] The high-viscosity colloid filling device of this invention comprises a sealing fixture, a vacuum pump, a vibrating element, and a dispensing tube that work together in a coordinated manner. When high-viscosity colloid needs to be injected into the inner cavity of the part to be dispensed: the part to be dispensed is first positioned in the sealing fixture, which facilitates the subsequent vacuum pump to evacuate the inner cavity, thus achieving the filling vacuum level. Then, the outlet end of the dispensing tube is extended downward along the Z-axis into the inner cavity to begin dispensing. That is, under the filling vacuum level, the gas content in the inner cavity is kept low, thereby ensuring that air bubbles are not easily generated during the subsequent dispensing process in a vacuum environment, ensuring the dispensing effect. At the same time, during the process of dispensing the high-viscosity colloid into the inner cavity, the vibrating element vibrates to drive the dispensing tube to vibrate synchronously, so that the high-viscosity colloid in the dispensing tube flows quickly and evenly into the inner cavity. The above-mentioned method of dispensing while vibrating has the following effects: 1) Due to the dispensing process... Continuous high-frequency vibration can vibrate and expel the gas originally dissolved in the high-viscosity colloid, reducing the gas content in the high-viscosity colloid, thereby ensuring the quality and performance of the part to be injected; 2) When the flow channel in the inner cavity is complex and tortuous, continuous vibration of the high-viscosity colloid can make the flow rate of the high-viscosity colloid faster and have a certain impact force, so that the high-viscosity colloid can directly fill the various bends and turns in the flow channel, thereby ensuring that the high-viscosity colloid is fully filled in various positions in the complex and tortuous flow channel, thereby improving the full filling rate of the high-viscosity colloid in the inner cavity; and, because the high-viscosity colloid is fully filled in the complex and tortuous flow channel, and the vibration can make the flow rate of the high-viscosity colloid more uniform, it can avoid the problem of some positions being overfilled and others being underfilled in the inner cavity, thereby ensuring the uniformity of the high-viscosity colloid filling in the inner cavity.

[0031] The high-viscosity colloid filling method of the present invention, based on the above-mentioned high-viscosity colloid filling device, can ensure the quality and performance of the part to be filled after colloid filling; at the same time, it can improve the full filling rate of high-viscosity colloid in the inner cavity and ensure the uniformity of high-viscosity colloid filling in the inner cavity; and the entire colloid filling operation is simple and convenient, saves time and effort, and has a low colloid filling cost.

[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] This embodiment provides a high-viscosity colloid filling device. This device can automatically, quickly, fully, and uniformly inject high-viscosity colloid into the inner cavity of the part to be filled, thereby achieving insulation protection, waterproof protection, and aesthetic functions for the part after filling. Simultaneously, the device can effectively expel gas originally dissolved in the high-viscosity colloid during the filling process through vibration, thus ensuring the quality and performance of the part. Furthermore, the device has a simple and compact structure and low cost. Specifically, the high-viscosity colloid refers to a viscous colloid with a viscosity greater than 50,000 cP; the part to be filled can be a motor, solenoid valve, or controller; and the high-viscosity colloid is injected into the various complex, tortuous channels within the inner cavity.

[0044] Specifically, such as Figure 1 As shown, the high-viscosity colloid filling device includes a sealing fixture 1, a vacuum pump 2, a vibrating element 3, and a dispensing tube 4. The sealing fixture 1 is disposed within the dispensing space 10, and a component 20 to be dispensed is positioned within it. The vacuum pump 2 is mounted on the sealing fixture 1 and is used to evacuate the inner cavity 201 of the component 20 to achieve a filling vacuum level. The vibrating element 3 is slidably connected to the first inner wall 101 of the dispensing space 10 along the Z-axis and can stop at any position. The inlet end 41 of the dispensing tube 4 is connected to the vibrating element 3, and the outlet end 42 of the dispensing tube 4 extends downward along the Z-axis into the inner cavity 201. The vibrating element 3 drives the dispensing tube 4 to vibrate synchronously, causing the high-viscosity colloid within the dispensing tube 4 to vibrate and be injected into the inner cavity 201. The filling vacuum level involved in this embodiment needs to be determined based on the specific filling conditions and actual vacuum requirements, and is not specifically limited here.

[0045] Compared with the prior art, the high-viscosity colloid filling device in this embodiment changes the specific method of filling the high-viscosity colloid into the inner cavity 201. By setting up a mutually cooperating sealing fixture 1, vacuum pump 2, vibrating element 3, and injection tube 4, when it is necessary to inject high-viscosity colloid into the inner cavity 201 of the part to be injected 20: first, the part to be injected 20 is positioned in the sealing fixture 1, which facilitates the subsequent vacuum pump 2 to evacuate the inner cavity 201, so that the vacuum degree of the inner cavity 201 is the filling vacuum degree, and then the injection tube 4... The outlet end 42 extends downward along the Z-axis into the inner cavity 201 to begin glue injection; that is, under the filling vacuum, the gas content in the inner cavity 201 can be kept low, thereby ensuring that air bubbles are not easily generated during the subsequent glue injection process in a vacuum environment, and ensuring the glue injection effect; at the same time, during the process of injecting high-viscosity glue into the inner cavity 201 through the glue injection tube 4, the vibrating element 3 vibrates to drive the glue injection tube 4 to vibrate synchronously, so that the high-viscosity glue in the glue injection tube 4 flows quickly and evenly into the inner cavity 201; the above The method of simultaneous vibration and adhesive injection has the following effects: 1) Due to the continuous high-frequency vibration during the injection process, the gas originally dissolved in the high-viscosity adhesive can be vibrated out, reducing the gas content in the high-viscosity adhesive, thereby ensuring the quality and performance of the part to be injected 20; 2) When the flow channel in the inner cavity 201 is complex and tortuous, the continuous vibration of the high-viscosity adhesive can make the flow rate of the high-viscosity adhesive faster and have a certain impact force, so that the high-viscosity adhesive can directly fill the various bends and turns in the flow channel, thereby ensuring that the high-viscosity adhesive is fully filled at various positions in the complex and tortuous flow channel, thus improving the full filling rate of the high-viscosity adhesive in the inner cavity 201; and, due to the full filling of the high-viscosity adhesive in the complex and tortuous flow channel, and the vibration can make the flow rate of the high-viscosity adhesive more uniform, it can avoid the problem of some positions being overfilled and others being underfilled in the inner cavity 201, thereby ensuring the uniformity of the high-viscosity adhesive filling in the inner cavity 201.

[0046] Furthermore, the high-viscosity colloid filling device in this embodiment mainly includes a sealing fixture 1 with a simple structure and low production cost, a vacuum pump 2, a vibrating element 3, and a glue injection tube 4. This makes the structure of the entire high-viscosity colloid filling device relatively simple and the production cost low. At the same time, it is only necessary to turn on the vibrating element 3 to vibrate, without any other additional operations, thereby ensuring that the entire glue injection filling operation is simple, convenient, time-saving, and labor-saving.

[0047] Furthermore, such as Figure 1As shown, the outlet end 42 of the dispensing tube 4 is located near the bottom surface 2011 of the inner cavity 201; that is, the dispensing tube 4 extends downward along the Z-axis to near the bottom surface 2011 of the inner cavity 201, so as to ensure that the high-viscosity adhesive is injected into the bottom of the inner cavity 201 when the dispensing tube 4 starts dispensing adhesive; in this embodiment, the dispensing filling method from bottom to top is adopted. Compared with the dispensing filling method from top to bottom, it can better avoid the generation of voids and air bubbles during the injection of high-viscosity adhesive, so as to better ensure that air bubbles are not easily generated during the entire filling process, and thus better ensure the dispensing filling effect.

[0048] Specifically, such as Figure 1 As shown, the sealing fixture 1 includes a lower fixture 11 and an upper fixture 12. The part to be injected with adhesive 20 is positioned on the lower fixture 11. The upper fixture 12 is slidably connected to the second inner wall 102 of the injection space 10 along the Z-axis, allowing the upper fixture 12 to move along the Z-axis, thereby enabling it to seal against or move away from the lower fixture 11. When the upper fixture 12 seals against the lower fixture 11, the part to be injected with adhesive 20 is confined within the sealed space 14 formed by the seal between the upper fixture 12 and the lower fixture 11, and the outlet end 42 of the injection tube 4 passes downwards along the Z-axis through the upper fixture 12 to extend into the inner cavity 201 for adhesive filling. Here, the specific structure of the upper fixture 12 and the lower fixture 11 is not limited, as long as it ensures that the part to be injected with adhesive 20 is confined within the sealed space 14 formed by the seal between the upper fixture 12 and the lower fixture 11. The second inner sidewall 102 is opposite to and spaced apart from the first inner sidewall 101.

[0049] By limiting the part to be injected 20 to be placed in the sealed space 14 formed by the upper fixture 12 and the lower fixture 11, on the one hand, it is easy to accurately position and fix the part to be injected 20, thereby ensuring the stability and reliability of subsequent injection filling; on the other hand, placing the part to be injected 20 in the sealed space 14 makes it easier for the vacuum pump 2 to evacuate the inner cavity 201 in the sealed space 14.

[0050] Furthermore, such as Figure 1 As shown, the sealing fixture 1 also includes a first sealing ring 13, which is circumferentially disposed on the top surface of the lower fixture 11. When the upper fixture 12 is sealed against the lower fixture 11, the upper fixture 12 can abut against the first sealing ring 13, thereby sealing the gap between the upper fixture 12 and the lower fixture 11 through the first sealing ring 13, thus ensuring that the upper fixture 12 and the lower fixture 11 are sealed together to form the aforementioned sealed space 14. In this embodiment, the first sealing ring 13 can specifically be an O-ring.

[0051] Specifically, a positioning groove is recessed on the top surface of the lower fixture 11, and the part to be injected 20 is locked in the positioning groove to ensure accurate positioning of the part to be injected 20 on the lower fixture 11. This prevents the part to be injected 20 from shaking or moving on the lower fixture 11, thereby ensuring the accuracy and stability of the position of the part to be injected 20 on the lower fixture 11. The first sealing ring 13 is spaced at the outer periphery of the positioning groove to avoid interference between the first sealing ring 13 and the positioning groove.

[0052] Specifically, such as Figure 1 As shown, when the upper fixture 12 and the lower fixture 11 are sealed together, the bottom end face of the upper fixture 12 is tightly attached to the top end face of the lower fixture 11, and the first sealing ring 13 is placed between the bottom end face of the upper fixture 12 and the top end face of the lower fixture 11. The inner side of the upper fixture 12 is limited and abuts against the outer side of the part to be injected with glue 20, so that the part to be injected with glue 20 can be limited and surrounded inside by the upper fixture 12, and then the part to be injected with glue 20 can be limited and positioned in the sealed space 14 by the cooperation between the upper fixture 12 and the lower fixture 11.

[0053] Furthermore, such as Figure 1 As shown, a first guide block 121 is connected to one outer side of the upper fixture 12, and a first guide rail 1021 extending along the Z-axis is provided on the second inner sidewall 102 of the glue injection space 10. The first guide block 121 can slide along the Z-axis on the first guide rail 1021. Specifically, the first guide block 121 can be automatically slid on the first guide rail 1021 by being driven by a motor, and the actual sliding speed of the first guide block 121 can be controlled by a controller commonly used in the prior art, that is, the motor and the controller are connected for control.

[0054] By allowing the first guide block 121 to slide along the Z-axis on the first guide rail 1021, on the one hand, the sliding of the first guide block 121 can drive the entire upper fixture 12 to reciprocate along the Z-axis, thereby enabling the upper fixture 12 to move along the Z-axis and stop at any position (if the motor stops working, the first guide block 121 cannot continue to slide on the first guide rail 1021); on the other hand, it can provide guidance for the movement of the upper fixture 12 on the Z-axis, thereby ensuring the guidance and stability of the movement of the upper fixture 12 relative to the lower fixture 11 on the Z-axis.

[0055] Specifically, such as Figure 1As shown, a connector 122 is threadedly connected to the top of the upper fixture 12. The first interface 1221 of the connector 122 passes through the upper fixture 12 and extends into the inner cavity 201 along the Z-axis, thereby facilitating the vacuum pump 2 to evacuate the inner cavity 201. Furthermore, by turning the connector 122, the connector 122 can be screwed in or out of the upper fixture 12, thereby adjusting the specific length of the first interface 1221 extending into the inner cavity 201 (the first interface 1221 extending longer or shorter into the inner cavity 201), thus meeting various vacuuming requirements. The second interface 1222 of the connector 122 is connected to the vacuum pump 2 via a first flexible hose 1223, allowing the first flexible hose 1223 to be used to adjust the thread rotation of the connector 122 relative to the upper fixture 12. The connector 122 can be any commonly used threaded adjustable connector in the prior art.

[0056] Furthermore, by sealing the first interface 1221 of the connector 122 downward along the Z-axis through the upper fixture 12 and extending into the inner cavity 201, a tight seal between the first interface 1221 and the upper fixture 12 can be ensured, thereby better guaranteeing the formation of the aforementioned sealed space 14. An O-ring can be provided between the first interface 1221 and the upper fixture 12 to ensure a tight seal between them.

[0057] Furthermore, such as Figure 1 As shown, the high-viscosity colloid filling device also includes a dispensing pump 5 and a second sealing ring 7. A second flexible hose 6 connects the dispensing pump 5 to the dispensing tube 4. The dispensing pump 5 is used to pump the high-viscosity colloid from the storage tank into the dispensing tube 4. That is, the dispensing pump 5 provides a certain pressure to the high-viscosity colloid in the storage tank, allowing it to be smoothly pressed into the inner cavity 201 through the dispensing tube 4. Furthermore, a second sealing ring 7 is installed inside the upper fixture 12, and the dispensing tube 4 slides along the Z-axis against the second sealing ring 7. This ensures a tight seal between the dispensing tube 4 and the upper fixture 12, thereby better ensuring the formation of the aforementioned sealed space 14. In this embodiment, the second sealing ring 7 can specifically be an O-ring.

[0058] Specifically, the vibrating element 3 is an ultrasonic vibration generator. The ultrasonic vibration generator can utilize the magnetostrictive effect, such as the periodic mechanical stretching vibration of certain ferromagnetic materials (e.g., nickel or cobalt) in an alternating magnetic field, to generate ultrasonic waves. On the one hand, it can ensure that the vibration effect of the vibrating element 3 on the dispensing tube 4 is good, thereby better ensuring that the high-viscosity adhesive strip in the dispensing tube 4 is quickly and evenly filled into various positions of the inner cavity 201. On the other hand, since the ultrasonic vibration amplitude generated by the vibrating element 3 is extremely small, it can ensure that the vibrating element 3 remains stationary (or floats very slightly) in its original position during the vibration process, thereby ensuring the positional stability of the vibrating element 3 during the vibration process.

[0059] Furthermore, such as Figure 1 As shown, a second guide block 31 is connected to one outer side of the vibrating element 3, and a second guide rail 1011 extending along the Z-axis is provided on the first inner sidewall 101 of the glue injection space 10. The second guide block 31 can slide along the Z-axis on the second guide rail 1011 to drive the glue injection tube 4 to move into or out of the inner cavity 201 along the Z-axis. The sliding of the second guide block 31 on the Z-axis is basically similar to the sliding of the first guide block 121 described above. Here, the sliding of the second guide block 31 will not be described in detail.

[0060] By sliding the second guide block 31 along the Z-axis on the second guide rail 1011, on the one hand, the sliding of the second guide block 31 can drive the vibrating element 3 and the glue injection tube 4 to reciprocate along the Z-axis, thereby enabling the vibrating element 3 to move along the Z-axis and stop at any position (same as the stopping operation of the first guide block 121 mentioned above); on the other hand, it can provide guidance for the movement of the vibrating element 3 on the Z-axis, thereby ensuring the guidance and stability of the movement of the vibrating element 3 and the glue injection tube 4 on the Z-axis.

[0061] In this embodiment, the high-viscosity colloid filling device places the part to be injected 20 within a sealed space 14 formed by the upper fixture 12 and the lower fixture 11, which facilitates the vacuum pump 2 to evacuate the inner cavity 201. Furthermore, by directing the injection tube 4 downward along the Z-axis to the bottom surface 2011 of the inner cavity 201, voids and air bubbles can be avoided during the injection of high-viscosity colloid, thus ensuring the filling effect. At the same time, by evacuating the inner cavity 201 to a filling vacuum level, air bubbles are less likely to be generated during the subsequent injection process in a vacuum environment, ensuring the filling effect.

[0062] In this embodiment, the high-viscosity colloid filling device connects a vibrating element 3 to the dispensing tube 4. Simultaneously, the vibrating element 3 vibrates the dispensing tube 4 to synchronously vibrate the high-viscosity colloid within it, thereby dislodging the gas originally dissolved in the high-viscosity colloid. At the same time, it improves the flow state of the high-viscosity colloid within the dispensing tube 4, allowing it to quickly and evenly fill all bends and turns within the flow channel. This ensures sufficient and uniform filling of the high-viscosity colloid at various locations within the complex and winding flow channel.

[0063] Example 2

[0064] This embodiment provides a high-viscosity colloid filling method, which automatically, quickly and uniformly fills the high-viscosity colloid into the desired locations within the inner cavity 201 of the part to be filled with colloid based on the high-viscosity colloid filling device described in Embodiment 1 above.

[0065] Specifically, such as Figure 2 As shown, the high-viscosity colloid filling method includes the following steps: S1: Position the part to be injected 20 inside the sealing fixture 1, and use the vacuum pump 2 to evacuate the inner cavity 201 until the vacuum degree of the inner cavity 201 is the filling vacuum degree; then extend the outlet end 42 of the injection tube 4 downward along the Z-axis into the inner cavity 201; S2: Inject the high-viscosity colloid into the inner cavity 201 through the injection tube 4; at the same time, vibrate the vibrating element 3 to drive the injection tube 4 to vibrate synchronously, so that the high-viscosity colloid in the injection tube 4 flows and fills the inner cavity 201; S3: When injecting into the inner cavity 201, the high-viscosity colloid is injected into the inner cavity 201 through the injection tube 4. When a preset amount of high-viscosity colloid is injected into the inner cavity 201, the injection stops; and the vibrating element 3 continues to vibrate to drive the dispensing tube 4 to vibrate synchronously for a preset time, after which the vibrating element 3 stops vibrating; S4: The vibrating element 3 drives the dispensing tube 4 to rise upward along the Z-axis from the inner cavity 201 at a lifting rate. At the same time, the dispensing tube 4 injects high-viscosity colloid into the inner cavity 201 at a dispensing rate to fill the gap space after the dispensing tube 4 is lifted and withdrawn from the inner cavity 201, and the vibrating element 3 vibrates to drive the dispensing tube 4 to vibrate synchronously, with the lifting rate matching the dispensing rate. The preset amount and preset time involved in this embodiment need to be determined according to the actual filling conditions, and are not specifically limited here.

[0066] By employing the above-described filling steps, on the one hand, when injecting high-viscosity colloid into the inner cavity 201 through the injection tube 4, the gas in the high-viscosity colloid can be expelled by vibration, ensuring sufficient and uniform filling. On the other hand, when the injection tube 4 is lifted upward after the filling is completed, a method of vibrating while injecting colloid and lifting is adopted, and the lifting rate is matched with the injection rate, thereby ensuring that no air bubbles are generated during the entire lifting process, thus better ensuring the overall filling effect. At the same time, it ensures that after the filling is completed and the injection tube 4 is lifted and withdrawn along the Z-axis, the gap space left by the lifting and withdrawal of the injection tube 4 continues to be filled, thereby ensuring the integrity and effect of the filling in the inner cavity 201.

[0067] The specific filling process of the high-viscosity colloid filling method in this embodiment is as follows:

[0068] First, the part to be injected with adhesive 20 is locked in the positioning groove of the lower fixture 11, and the first guide block 121 slides down along the Z-axis on the first guide rail 1021, simultaneously driving the upper fixture 12 to move down along the Z-axis to seal and fit the lower fixture 11, so as to limit the part to be injected with adhesive 20 in the sealed space 14.

[0069] Next, vacuum pump 2 is used to evacuate the inner cavity 201 to achieve the required vacuum level for filling. Then, the second guide block 31 slides downward along the Z-axis on the second guide rail 1011, simultaneously driving the vibrating element 3 and the dispensing tube 4 to move downward along the Z-axis until the outlet end 42 of the dispensing tube 4 passes through the upper fixture 12 and reaches near the bottom surface 2011 of the inner cavity 201. Throughout the entire dispensing process, vacuum pump 2 remains on to evacuate the inner cavity 201, ensuring that the vacuum level inside the inner cavity 201 is always at the required filling vacuum level.

[0070] Then, the dispensing pump 5 pumps the high-viscosity adhesive from the storage tank into the dispensing tube 4, so that the high-viscosity adhesive in the dispensing tube 4 is injected and filled from the bottom of the inner cavity 201. At the same time, the vibrating element 3 starts to vibrate, so as to drive the dispensing tube 4 and the high-viscosity adhesive inside it to vibrate synchronously, improve the flow state of the high-viscosity adhesive in the dispensing tube 4, so that the high-viscosity adhesive in the dispensing tube 4 flows quickly and evenly to fill the flow channels of the inner cavity 201, thereby effectively helping to fully fill the narrow flow channels and various bends and turns, and effectively squeezing out the gas originally dissolved in the high-viscosity adhesive.

[0071] Then, when a preset amount of high-viscosity colloid is injected into the inner cavity 201, the dispensing pump 5 stops dispensing; then, the vibrating element 3 continues to vibrate to drive the dispensing tube 4 to vibrate synchronously for a preset time, and then the vibrating element 3 stops vibrating, so as to ensure the complete discharge of the gas originally dissolved in the high-viscosity colloid, and to vibrate and fill all the high-viscosity colloid remaining in the dispensing tube 4 into the inner cavity 201.

[0072] Then, the second guide block 31 slides upward along the Z-axis on the second guide rail 1011 to synchronously drive the vibrating element 3 and the glue injection tube 4 to move upward along the Z-axis, so that the glue injection tube 4 is lifted upward along the Z-axis from the inner cavity 201 at a lifting rate; at the same time, the glue injection pump 5 pumps the high-viscosity glue in the storage tank into the glue injection tube 4, so that the high-viscosity glue in the glue injection tube 4 is injected and filled into the gap space after the glue injection tube 4 is lifted and withdrawn from the inner cavity 201 at the glue injection rate; at the same time, the vibrating element 3 vibrates to drive the glue injection tube 4 and the high-viscosity glue inside to vibrate synchronously, so as to achieve effective air venting, full filling and uniform filling during the process of simultaneous glue injection, lifting and withdrawal and vibration.

[0073] Then, when the dispensing tube 4 is completely removed from the inner cavity 201, the dispensing pump 5 is turned off, and the high-viscosity adhesive fills the gap space after the dispensing tube 4 is lifted and removed from the inner cavity 201. The vacuum pump 2 is then turned off after a set delay time to ensure the vacuum effect in the inner cavity 201.

[0074] Finally, the second guide block 31 slides upward along the Z-axis on the second guide rail 1011 to synchronously drive the vibrating element 3 and the glue injection tube 4 to move upward along the Z-axis until the glue injection tube 4 disengages from the upper fixture 12 along the Z-axis and returns to its initial position; and the first guide block 121 slides upward along the Z-axis on the first guide rail 1021 to synchronously drive the upper fixture 12 to move upward along the Z-axis until it disengages from the lower fixture 11, and then the glue-filled part 20 can be directly removed from the lower fixture 11; thus completing the entire glue filling process of the part 20 to be glued.
