Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, and in particular to a dispensing device for sensor processing. Background Technology

[0002] A dispensing device for sensor processing is a specialized piece of equipment used in the sensor manufacturing process for dispensing adhesives. Its function is to precisely apply liquid materials such as glue, conductive adhesive, and sealant to designated locations on the sensor to achieve the functions of encapsulation, fixation, conductivity, and sealing.

[0003] Current sensor processing dispensing devices use a control system to send commands to a motion system that moves the dispensing head to a designated dispensing position to complete the dispensing operation. However, because the dispensing head is too small, the adhesive may solidify and clog the dispensing head and pipes during the dispensing process, resulting in high maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dispensing device for sensor processing, which aims to improve the problem that the dispensing head is easily blocked during the operation of the dispensing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dispensing device for sensor processing, comprising a base plate, a bracket fixedly connected to the top of the base plate, a mover fixedly connected to the front side of the bracket, a connector fixedly connected to the front side of the mover, two heating shells fixedly connected to the front side of the connector, a storage tank fixedly connected inside each of the two heating shells, an ultrasonic vibrator fixedly connected to the top of the inner wall of each storage tank, a mixer fixedly connected to the bottom of the storage tank, a motor fixedly connected to the rear side of the mixer, a viscosity sensor and a discharge controller fixedly connected to the bottom of the mixer, a filter fixedly connected to the inner diameter of the discharge controller, a dispensing head provided at the bottom of the discharge controller, and a quick-release assembly provided at the bottom of the discharge controller.

[0011] Preferably, the top of the dispensing head passes through the electric snap fastener and the sealing ring, and the top of the dispensing head is tightly fitted to the bottom of the discharge controller.

[0012] Preferably, the number of teeth inside the electric buckle corresponds to the number of engagement slots, and the teeth and engagement slots of the electric buckle fit tightly together.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the temperature and vibration frequency of the glue are automatically adjusted by using a heating shell and an ultrasonic vibrator, and the glue is mixed by a mixer.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a dispensing device for sensor processing, comprising a base plate 1, a bracket 2 fixedly connected to the top of the base plate 1, a mover 3 fixedly connected to the front side of the bracket 2, a connector 4 fixedly connected to the front side of the mover 3, two heating shells 6 fixedly connected to the front side of the connector 4, a storage tank 5 fixedly connected inside each of the two heating shells 6, an ultrasonic vibrator 7 fixedly connected to the top of the inner wall of the storage tank 5, a mixer 8 fixedly connected to the bottom of the storage tank 5, a motor 9 fixedly connected to the rear side of the mixer 8, a viscosity sensor 10 and a discharge controller 12 fixedly connected to the bottom of the mixer 8, a filter 11 fixedly connected to the inner diameter of the discharge controller 12, a dispensing head 15 provided at the bottom of the discharge controller 12, and a quick-release assembly provided at the bottom of the discharge controller 12.

[0025] Specifically, when the dispensing device processes the sensor for dispensing, the mover 3 drives the dispensing head 15 to move left and right and up and down for adjustment. Then, the two different types of adhesives in the two storage tanks 5, namely the main adhesive and the curing agent, are automatically adjusted in temperature and oscillation frequency by the heating shell 6 and the ultrasonic oscillator 7. The adhesive then flows into the mixer 8, where it is stirred and mixed by the mixer 8 and the motor 9. During the mixing process, the viscosity sensor 10 detects the viscosity of the adhesive. If the viscosity is too high, the heating shell 6 and the ultrasonic oscillator 7 further heat and vibrate the subsequently added adhesive to ensure that the viscosity of the adhesive is moderate and will not cause blockage in the subsequent process. Finally, the adhesive is extracted from the mixer 8 by the discharge controller 12. When the adhesive flows into the dispensing head 15 through the discharge controller 12, it undergoes triple filtration by the filter 11 to prevent impurities in the adhesive from clogging the dispensing head 15, thus solving the problem of the dispensing head 15 being easily clogged during the operation of the dispensing device.

[0026] Reference Figures 4-5The quick-release assembly includes a magnetic mounting head 13, which is fixedly connected to the discharge controller 12. An electric latch 14 is fixedly connected to the bottom of the magnetic mounting head 13. A sealing ring 17 is fixedly connected to the inner diameter of the magnetic mounting head 13. A magnet 16 is fixedly connected to the top of the dispensing head 15. Four engaging grooves 18 are opened on the outer surface of the dispensing head 15.

[0027] Specifically, by providing a magnet 16 at the junction of the dispensing head 15 and the magnetic mounting head 13, when installing the dispensing head 15, after inserting it into the electric latching device 14 and the magnetic mounting head 13, the magnetic mounting head 13 magnetically attracts the dispensing head 15, thus initially fixing it in place. Then, the electric latching device 14 activates its locking teeth to engage with the engaging groove 18 on the outer surface of the dispensing head 15, thereby fixing the dispensing head 15 onto the dispensing device. During the insertion of the dispensing head 15 into the electric latching device 14, the protrusions on the outer surface of the dispensing head 15 correspond to the grooves on the bottom of the electric latching device 14, preventing incorrect installation angles. When replacing the dispensing head 15, simply close the latch of the electric latch 14 and the magnetic attraction of the magnetic mounting head 13 to remove the fixation and restriction of the dispensing head 15, thus quickly removing it from the dispensing device. This solves the problem of time-consuming disassembly when replacing the dispensing head 15.

[0028] Reference Figure 2 The motor 9 is fixedly connected to the connector 4, and the mixer 8 is fixedly connected to the connector 4.

[0029] Specifically, the motor 9 that drives the mixer 8 is located on the rear side of the mixer 8 and is fixed to the lower half of the connector 4, just like the mixer 8.

[0030] Reference Figure 3 The filter 11 consists of a nanofiber filter, a magnetic filter, and an electrostatic filter from top to bottom.

[0031] Specifically, nanofiber filters intercept large particles of impurities, magnetic filters adsorb metal debris, and electrostatic filters capture dust, thereby preventing impurities from clogging subsequent components.

[0032] Reference Figure 3 The mixer 8 is equipped with blades inside, and the blades of the mixer 8 are fixedly connected to the output end of the motor 9.

[0033] Specifically, after the colloid is transferred to the mixer 8, the motor 9 drives the blades inside the mixer 8 to fully blend the two colloids.

[0034] Reference Figure 5 The magnet 16 is magnetically connected to the magnetic head on the inner wall of the magnetic mounting head 13, and the sealing ring 17 is tightly fitted to the upper part of the dispensing head 15.

[0035] Specifically, when the dispensing head 15 is inserted into the electric snap fastener 14 and the magnetic mounting head 13, the magnetic head in the magnetic mounting head 13 attracts the magnet 16 on the dispensing head 15, and at the same time, the sealing ring 17 tightly wraps the outer surface of the dispensing head 15, thereby making the upper part of the dispensing head 15 connected stably.

[0036] Reference Figure 5 The top of the dispensing head 15 passes through the electric snap fastener 14 and the sealing ring 17, and the top of the dispensing head 15 is tightly fitted with the bottom of the discharge controller 12.

[0037] Specifically, after the dispensing head 15 is inserted into the electric clip 14 and the magnetic mounting head 13, the top of the dispensing head 15 is connected to the discharge controller 12, so that the adhesive is input into the dispensing head 15 through the discharge controller 12.

[0038] Reference Figures 4-5 The number of internal teeth of the electric buckle 14 corresponds to the number of engagement grooves 18, and the teeth of the electric buckle 14 and the engagement grooves 18 fit tightly together.

[0039] Specifically, when the dispensing head 15 is inserted into the electric latching device 14, the protrusions on the outer surface of the dispensing head 15 fit into the groove at the bottom of the electric latching device 14, limiting the insertion angle of the dispensing head 15, thereby allowing the locking teeth in the electric latching device 14 to engage with the locking groove on the outer surface of the locking groove 18.

[0040] Working principle: During dispensing, the main adhesive and curing agent are stored in dual storage tanks 5 respectively. The heating shell 6 regulates the temperature of the colloid through heat conduction, changing the intermolecular forces to adjust the fluidity. The ultrasonic oscillator 7 generates high-frequency vibration, which makes the colloid particles evenly dispersed and reduces the probability of agglomeration. The mixer 8 adopts a paddle-type structure and is driven by the motor 9 to form a turbulent field, which promotes full contact between different colloid molecules. The viscosity sensor 10 monitors the changes in fluid resistance in real time based on the vibration principle and feeds back the signal to the temperature control and oscillation module to form a closed-loop control system. When the viscosity is detected to deviate from the threshold, the energy input is automatically increased. The viscosity is reduced by increasing the temperature and enhancing the oscillation. The filter 11 adopts a gradient interception design. The nano-sized pore structure physically intercepts large particles of impurities. The magnetic medium uses the ferromagnetic effect to adsorb metal particles. The electrostatic field captures charged dust through Coulomb force. This composite filtration method covers pollutants with different physical properties, ensuring the purity of the colloid and thus avoiding clogging of the dispensing head 15.

[0041] During installation, the fit between the positioning protrusion and the groove ensures the correct installation angle and precise alignment of the colloid channel. The sealing ring 17 is made of elastomeric material and forms a radial sealing force through interference fit to prevent colloid leakage. During disassembly, power is cut off to demagnetize the electromagnetic head in the magnetic mounting head 13, and at the same time, the electric latch 14 reverses to release the latch teeth, allowing the dispensing head 15 to separate axially. The innovation of this design lies in combining two different physical fixing methods, permanent magnet adsorption and electric latch, which solves the problems of time-consuming tightening of traditional threaded connections and aging of sealing rings. This reduces the replacement operation time from several minutes in the traditional method to several seconds, meeting the rapid maintenance needs of automated production lines.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
