Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sealant injection, and particularly relates to an insulating silica gel sealing system. BACKGROUND

[0002] Insulating sealing silica gel is a kind of liquid silicone rubber. The most common sealing silica gel is electronic potting adhesive, which is commonly used for sealing electronic components and can also be used on the surface of materials such as PC (Poly-carbonate), PP, ABS, PVC and metal materials. The surface resistivity of the electronic potting adhesive can reach 1000 ohms, the tensile strength is greater than 4 MPa, the fracture growth rate is greater than 80%, and the thermal conductivity is 0.1 w / m·K. The electronic potting adhesive can be used at -40 DEG C to 120 DEG C. The electronic potting adhesive has the characteristics of low viscosity, good flowability, easy injection, no heat release after curing, good insulation performance, waterproof and moisture-proof, small shrinkage, no corrosion to electronic components and the like, and can prolong the service life of electronic components.

[0003] During the electronic component injection process of the electronic potting adhesive, the viscosity of the electronic potting adhesive at room temperature is 6000-8000 mPa·s, which causes slow flow and cannot quickly fill the internal electronic components, so that the electronic potting adhesive often cannot be uniformly injected or filled during the injection process, thereby causing bubbles and voids around the electronic components. After the injection is completed, the internal voids and bubbles expose part of the internal components of the electronic components, affect the sealing performance of the electronic components, easily cause the failure of the electronic components, and reduce the service life. During the injection process of the electronic potting adhesive, if the injection is stopped under the condition that the internal electronic potting adhesive is not fully filled, the internal injection will be insufficient, if the injection is continuously performed, the electronic potting adhesive will overflow and be wasted, and the electronic components and the injection device need to be cleaned again. The surface of the electronic potting adhesive needs to be cured for about two hours. In order to ensure sufficient injection, the electronic potting adhesive will overflow the surface to produce excess glue, and the excess glue is still in a liquid flow state at this time. The excess glue is usually treated by wiping, which causes unnecessary cost and resource waste.

[0004] In view of the above problems, the prior art provides certain technical inspiration. The prior art is provided with a swing and uniform injection mechanism, and a bearing plate is arranged in the swing and uniform injection mechanism. The bearing plate can drive the electronic components to swing left and right. After testing, the inventor finds that the above technology still has the problems of uneven injection, poor uniform injection effect and low efficiency when the swing speed and swing amplitude are too small. When the swing speed and swing amplitude are too large, the insulating sealing silica gel will splash during injection, and the insulating sealing silica gel will overflow from the top edge of the electronic components after the electronic components are filled with the insulating sealing silica gel due to the swing, thereby causing the horizontal plane of the insulating sealing silica gel in the electronic components to drop and the top of the electronic components to be exposed again.

[0005] In view of this, the application provides an insulating silica gel sealing system which can fill the silica gel evenly and sufficiently and recycle the excess silica gel. SUMMARY

[0035] As an embodiment of the present application, as shown in Figure 7As shown, the circular protrusions 311 are arranged on the sliding surface of the first slider 32 and the annular guide rail 31, and the circular protrusions 311 on the sliding surface of the first slider 32 and the annular guide rail 31 are matched, so that when the first slider 32 slides on the annular guide rail 31, the first slider 32 will shake, and the first slider 32 will transmit the shaking to the erasing rod 33, and the erasing rod 33 will transmit the shaking to the electronic components through the erasing block 34, so that the electronic components can shake to some extent, so as to accelerate the flow of the insulating and sealing silica gel in the electronic components, and the auxiliary unit 6 can more effectively remove the internal gaps and bubbles.

[0036] As an embodiment of the present application, as shown in Figure 5 and Figure 6 As shown, the glue injection unit 4 includes a communication pipe 41, a discharge pipe 42, an electric control valve 43, a feeding pipe 44, a receiving disc 45 and a glue outlet pipe 46. The communication pipe 41 is arranged in the annular guide rail 31 and along the length direction of the annular guide rail 31. The communication pipe 41 is connected with a glue injection pump (not shown in the figure), which is used to transport the insulating and sealing silica gel in a storage tank (not shown in the figure) to the communication pipe 41. The lower part of the communication pipe 41 is provided with the discharge pipe 42, which is uniformly arranged with four along the length direction of the communication pipe 41, and the lower end of the discharge pipe 42 extends to the lower surface of the annular guide rail 31. The lower part of the discharge pipe 42 is provided with the electric control valve 43. The erasing rod 33 is a hollow structure, and the feeding pipe 44 is arranged in the erasing rod 33. One end of the feeding pipe 44 is connected with the receiving disc 45, and the other end of the feeding pipe 44 is connected with the glue outlet pipe 46. The glue outlet pipe 46 is arranged on the top of the erasing block 34. The glue outlet pipe is used to drive the erasing rod 33 and the erasing block 34 to move and change position when the first slider 32 makes annular sliding on the lower surface of the annular guide rail 31.

[0037] As an embodiment of the present application, as shown in Figure 5As shown, the receiving tray 45 is rectangular in structure, is fixedly installed inside the first sliding block 32, the receiving groove is corresponded to the outlet of the electric control valve 43, and the top of the receiving tray 45 is attached to the bottom of the annular guide rail 31; the bottom of the receiving tray 45 is provided with a discharge port connected with the glue outlet pipe 46; the receiving tray 45 is made of rubber material; the bottom of the annular guide rail 31 is provided with an annular groove, the discharge port of the electric control valve 43 is located at the bottom of the annular groove, and the receiving tray 45 is located in the annular groove and slides; when the first sliding block 32 continuously slides below the annular guide rail 31, the receiving tray 45 made of rubber material can ensure that the sliding surface of the first sliding block 32 and the annular guide rail 31 keeps in contact, and at the same time, due to the circular protrusions 311 arranged on the sliding surface of the first sliding block 32 and the annular guide rail 31, the first sliding block 32 can stably shake when sliding along the annular guide rail 31, thereby ensuring the stability of the first sliding block 32 when shaking.

[0038] As an embodiment of the present application, as shown in the drawings, Figures 2 to 4 As shown, the sliding unit 5 includes a second sliding block 51, a guide rail 52, a fixed base 53, a clamping block 54, a first electric push rod 55 and a second electric push rod 56, the guide rail 52 is arranged below the auxiliary unit 6, the end of the guide rail 52 is welded to the lower surface of the discharge port 12, the discharge port 12 is used for feeding and discharging electronic components by the second sliding block 51, the second sliding block 51 is slidingly connected to the upper surface of the guide rail 52, and the second sliding block 51 is located directly below the erasing unit 3 and the auxiliary unit 6 when glue injection, the fixed base 53 is fixedly arranged on the upper surface of the second sliding block 51, and the fixed base 53 is used for fixing electronic components, thereby facilitating glue injection of the electronic components by the glue injection pipe 46; the clamping block 54 is arranged inside the side wall around the fixed base 53, the top of the clamping block 54 is provided with an inverted trapezoidal groove structure 541, the bottom of the inverted trapezoidal groove structure 541 is arranged in a length direction, the side wall of the clamping block 54 is provided with the second electric push rod 56, the clamping block 54 is used for limiting and fixing the electronic components placed in the fixed base 53, the lowest part of the bottom of the inverted trapezoidal groove structure 541 in the top of the clamping block 54 is communicated with a recovery pipe, the recovery pipe is arranged in four and penetrates through the side wall of the fixed base 53; the second electric push rod 56 is arranged between the clamping block 54 and the fixed base 53, the second electric push rod 56 can adjust the clamping of electronic components, so that different electronic components can be clamped, the second electric push rod 56 is electrically connected with a controller, and the controller is used for controlling the extension and retraction of the second electric push rod 56;

[0039] The inclined bottom of the inverted trapezoidal groove structure 541 can facilitate the circulation of the insulating sealing silica gel in the inverted trapezoidal groove structure 541 to the recovery pipe, which can recycle the residual glue removed by the erasing unit 3. When the residual glue is removed by the erasing block 34 adhering to the top of the electronic component, the residual glue flows into the inverted trapezoidal groove structure 541 under the pushing of the erasing block 34, and quickly circulates in the recovery pipe under the action of the inclined bottom of the inverted trapezoidal groove structure 541. The recovery pipe circulates the insulating sealing silica gel to the storage tank for reuse. The storage tank is used to store the insulating sealing silica gel. At this time, the recycling of the residual glue can be completed, which can effectively reduce the cost and waste of resources.

[0040] The first electric push rod 55 is arranged at the upper end of the guide rail 52 and is welded to the side wall of the shell 1. The rod of the first electric push rod 55 is connected to the second sliding block 51 by bolts. The first electric push rod 55 is electrically connected to the controller, which is used to control the extension and retraction of the first electric push rod 55. The first electric push rod 55 is used to make the second sliding block 51 reciprocate on the upper surface of the guide rail 52. When injecting glue, the first electric push rod 55 can drive the second sliding block 51 to slide slightly on the upper surface of the guide rail 52, which can further accelerate the flow of the insulating sealing silica gel in the electronic component, avoid the formation of gaps and bubbles in the electronic component, and further improve the efficiency.

[0041] As an embodiment of the present application, as shown in Figures 2 to 4 The auxiliary unit 6 includes a fan 61 arranged at the top of the shell 1 and located at the center of the annular guide rail 31. During the glue injection process, the fan 61 is located directly above the fixed base 53. The fan 61 can rotate to form air pressure, and air can exert downward pressure on the insulating sealing silica gel in the electronic component, thereby accelerating the flow of the insulating sealing silica gel in the electronic component. At the same time, the gas blown by the fan 61 can accelerate the solidification of the insulating sealing silica gel in the electronic component. In the case of reducing the flow time of the insulating sealing silica gel in the electronic component, the glue injection efficiency of the insulating sealing silica gel is further improved. The airflow generated by the fan 61 can be discharged from the discharge port 12, which can make the air pressure generated by the fan 61 more stable, and the air pressure can make the insulating sealing silica gel in the electronic component more uniform.

[0042] As an embodiment of the present application, as shown in Figure 5As shown, the lower surface of the annular guide rail 31 is provided with an impact first switch 431, and the inside of the first slider 32 is provided with an impact second switch 321 corresponding to the impact first switch 431. The moment of the impact second switch 321 is greater than that of the impact first switch 431. The first slider 32 stops when it slides in the annular guide rail 31 to the position directly below the discharge pipe 42. The impact second switch 321 collides with the impact first switch 431 to cause displacement. At this time, since the moment of the impact second switch 321 is greater than that of the impact first switch 431, the impact first switch 431 is triggered. At this time, the impact first switch 431 controls the electric control valve 43 to open and the glue injection pump to inject glue. The insulating sealing silica gel can flow in the discharge pipe 42 to the receiving disc 45, and then through the conveying pipe 44 to the glue outlet pipe 46 for glue injection. After a period of time, the first slider 32 slides away from the position directly below the discharge pipe 42. At this time, the impact first switch 431 returns to the original position. At this time, the electric control valve 43 and the glue injection pump are closed at the same time, and the insulating sealing silica gel is cut off in the discharge pipe 42.

[0043] The glue outlet pipe 46 is provided with a flow sensor 47 fixedly arranged at the end of the erasing rod 33 close to the glue outlet pipe 46. The flow sensor 47 is electrically connected with the controller, and the controller is electrically connected with the impact first switch 431. The controller is used to control the impact first switch 431 to be locked or unlocked according to the amount of glue injection detected by the flow sensor 47. It should be understood that the locking of the impact first switch 431 means that the impact first switch 431 cannot control the electric control valve 43 and the glue injection pump to work, while the unlocking of the impact first switch 431 means that the impact first switch 431 can control the electric control valve 43 and the glue injection pump to work.

[0044] The flow sensor 47 is used to detect the insulating sealing silica gel flowing in the glue outlet pipe 46, so that the glue outlet pipe 46 can quantitatively inject glue to the electronic component, thereby avoiding waste of the insulating sealing silica gel caused by excessive injection of glue, and avoiding glue pollution caused by overflow of the insulating sealing silica gel. When the controller detects, through the flow sensor 47, that the insulating sealing silica gel filled in the glue outlet pipe 46 does not reach the set value, the controller does not control the impact first switch 431, and at this time, the impact first switch 431 is in an unlocked state; when the controller detects, through the flow sensor 47, that the insulating sealing silica gel filled in the glue outlet pipe 46 reaches the set value, the controller controls the impact first switch 431 to be self-locked, and when the first sliding block 32 slides to be directly below the discharge pipe 42, at this time, since the impact first switch 431 is in a self-locked state, the first switch 431 cannot be triggered, the impact second switch 321 is triggered, the impact first switch 431 can smoothly pass through the trigger point, the first sliding block 32 can normally slide on the lower surface of the annular guide rail 31, but no glue is injected, and the first sliding block 32 can drive the erasing rod 33 and the erasing block 34 to continuously erase residual glue on the top surface of the electronic component when the first sliding block 32 slides.

[0045] As an embodiment of the present application, the fan 61 is electrically connected with the controller, the controller controls the rotating speed of the fan 61 according to the amount of injected glue detected by the flow sensor 47, and the rotating speed of the fan 61 is inversely proportional to the amount of injected glue. When the amount of injected glue is small and the wind force is large, the insulating sealing silica gel at the bottom of the electronic component can flow more quickly, and gaps and bubbles caused by splashing of the insulating sealing silica gel cannot be caused; when the amount of injected glue is large and the wind force is small, the insulating sealing silica gel at the top of the electronic component cannot overflow and the horizontal plane cannot be uneven when the electronic component is filled with the insulating sealing silica gel.

[0046] In work, the second sliding block 51 and the fixed base 53 are located at the discharge port 12 of the shell 1, at this time, the operator places the electronic component in the fixed base 53, the controller controls the second electric push rod 56 to extend, the second electric push rod 56 pushes the clamping block 54 to clamp the electronic component; then, the controller controls the first electric push rod 55 to retract, and moves the second sliding block 51, the fixed base 53 and the electronic component to be directly below the fan 61; then, the controller controls the fan 61 to rotate, and at the same time, the controller controls the motor 35 to work, the motor 35 cooperates with the friction wheel 36 to drive the first sliding block 32 to slide along the annular guide rail 31; in the process of sliding, the impact first switch 431 collides with the impact second switch 321, the impact first switch 431 is triggered, and the impact first switch 431 controls the electric control valve 43 and the glue injection pump to work at the same time, the glue injection pump delivers the glue in the glue storage tank to the communication pipe 41, then the glue passes through the discharge pipe 42, the electric control valve 43, the glue receiving disc 45 and the glue conveying pipe 44, and is discharged to the surface of the electronic component through the glue outlet pipe 46.

[0047] During the glue dispensing process, the flow sensor 47 detects the flow rate of the glue discharged from the glue dispensing tube 46, and the controller controls the impact-type first switch 431 and the fan 61 to work based on the result detected by the flow sensor 47. Specifically, when the controller detects through the flow sensor 47 that the amount of insulating and sealing silicone injected into the dispensing tube 46 has not reached the set value, the controller does not control the impact-type first switch 431, and the impact-type first switch 431 is in the unlocked state. When the controller detects through the flow sensor 47 that the amount of insulating and sealing silicone injected into the dispensing tube 46 has reached the set value, the controller controls the impact-type first switch 431 to self-lock. When the first slider 32 slides directly below the dispensing tube 42, the first switch 431 will not be triggered because it is in the self-locked state, while the impact-type second switch 321 will be triggered, allowing the impact-type first switch 431 to pass the trigger point smoothly. This ensures that the first slider 32 slides normally on the lower surface of the annular guide rail 31, but no glue is dispensed. This allows the first slider 32 to drive the wiping rod 33 and the wiping block 34 to continuously wipe away the residual glue on the top surface of the electronic components when it slides. When the flow sensor 47 detects that the amount of insulating and sealing silicone injected into the dispensing tube 46 is gradually increasing, the controller controls the fan 61 to gradually reduce its speed. When the controller detects through the flow sensor 47 that the amount of insulating and sealing silicone injected into the dispensing tube 46 has reached a set value, the controller controls the fan 61 to stop rotating.

[0048] The remaining adhesive falls into the inverted trapezoidal groove structure 541 at the top of the clamping block 54 under the push of the wiping block 34. The inverted trapezoidal groove structure 541 is connected to the recycling pipe.
