Description

Technical Field

[0001] The invention relates to the technical field of rosin waste gas purification equipment, in particular to an electrode structure for purifying rosin-containing gas. Background Art

[0002] In the process of chip and semiconductor processing, soldering flux is often used. Rosin, as the main component of soldering flux, is one of the key factors to ensure the stable connection between electronic components and PCBs. The rosin waste gas generated generally needs to be collected and treated before being discharged. In the prior art, there are many types of rosin waste gas recovery and treatment equipment, among which there are those that form an electrostatic field by connecting a high-voltage power supply to adsorb the rosin in the waste gas, thereby collecting it. The existing rosin waste gas collection source is often connected to multiple groups of chip processing equipment at the same time, resulting in changes in the amount of rosin waste gas collected and absorbed per unit time, which in turn causes the flow rate of rosin waste gas flowing into the electrostatic field per unit time to change. When the rosin waste gas flows into the electrostatic field at high speed, the electrostatic field does not have time to fully absorb the rosin in the waste gas, and the waste gas with rosin is discharged from the outlet.

[0003] Therefore, it is necessary to adaptively increase the electric field strength to improve the adsorption effect. However, the existing rosin gas purification equipment can generally only enhance the electric field strength by increasing the voltage, but this will bring about a large electricity cost, and there is a lack of an electrode structure that can adaptively adjust the electric field strength.

DETAILED DESCRIPTION

[0034] In order to make the objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides an electrode structure for purifying rosin-containing gas, which can form an electric field of uniform intensity to achieve the effect of stably removing rosin from waste gas, and includes: a collecting component 100, an electrode component 200 and a heating component 300. The waste gas containing rosin is collected and connected by setting the collecting component 100, and a stable electric field 203 in all directions is formed by arranging the electrode component 200, so that the rosin waste gas in all directions can be uniformly adsorbed, and the heating component 300 is set to increase the temperature, so that the adsorbed rosin is heated and melted, and then collected as rosin liquid for recovery.

[0039] Specifically, the collecting assembly 100 includes a housing 101 connected to an external power source, a collecting bin 102 disposed inside the housing 101, an air inlet 103 disposed at the bottom of the housing 101 and connected to the collecting bin 102, and an air outlet 104 disposed at the top of the housing 101 and connected to the collecting bin 102. The rosin waste gas just collected is generally at a higher temperature, so it moves upward after entering the collecting bin 102 from the lower air inlet 103, and is discharged from the air outlet 104 after the rosin is adsorbed and removed by the electrode assembly 200.

[0040] Furthermore, the electrode assembly 200 is arranged inside the shell 101, including a negative electrode 201 arranged on the inner side of the shell 101, a positive electrode 202 arranged on the inner wall of the shell 101 and spaced apart from the negative electrode 201, and an electric field 203 formed between the negative electrode 201 and the positive electrode 202 after the power is turned on. The negative electrode 201 is spaced apart from the positive electrode 202, and after the external power is connected, the negative charge on one side of the negative electrode 201 will move toward the positive electrode 202, thereby forming the electric field 203, and the rosin waste gas flows through the space between the negative electrode 201 and the positive electrode 202, and the rosin is adsorbed by the electric field 203.

[0041] The heating component 300 is disposed on the side wall of the positive electrode 202. In this embodiment, the heating component 300 is configured as a heating wire, and is separated from the positive electrode 202 by a heat-conducting material. When the heating wire is energized, current will pass through the wire material of the heating wire and generate impedance, converting electrical energy into thermal energy, thereby generating a high temperature in the heating wire, and utilizing the high temperature to heat and melt the rosin adsorbed on the inner wall of the positive electrode 202.

[0042] Preferably, the electric field 203 is located between the air inlet 103 and the air outlet 104, so that the rosin waste gas can fully pass through the electric field 203; the side where the negative electrode 201 and the positive electrode 202 are close to each other is set as an arc surface, and the electric field 203 formed between the arc-shaped electrodes is relatively stable. In this embodiment, the negative electrode 201 and the positive electrode 202 are concentric cylindrical shapes, and the electric field strength of the electric field 203 from the center of the circle to all directions is relatively uniform, so that the rosin waste gas has a balanced adsorption effect at all angles.

[0043] Working principle: The rosin waste gas generated during the chip processing is collected through a pipeline and passed into the collection chamber 102 from the air inlet 103. The rosin waste gas passes through the electric field 203 between the negative electrode 201 and the positive electrode 202 from bottom to top in the collection chamber 102. The negative charge in the electric field 203 flows from the negative electrode 201 to the positive electrode 202, which pushes the particles in the gas toward the positive electrode 202, thereby adsorbing the rosin particles contained in the waste gas to the positive electrode 202. The inner wall is then energized to heat the heating wire 300 on the side wall of the positive electrode 202. The rosin particles gather on the inner wall of the positive electrode 202 and are heated until the melting point is reached, so that the rosin particles are melted into rosin liquid. The gravity of the gathered rosin liquid is greater than the friction between it and the inner wall of the positive electrode 202, so that it flows down along the inner wall of the positive electrode 202 and gathers at the bottom of the shell 101, which is convenient for the subsequent collection and recovery of the rosin liquid, and the waste gas without the rosin is discharged from the outlet 104.

[0044] Example 2

[0045] Reference Figure 1-Figure 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a regulating component 400, which can adjust the intensity of the electric field 203 according to the change of the exhaust gas volume entering the air inlet 103 per unit time.

[0046] Specifically, it also includes an adjustment component 400 arranged on the inner side of the shell 101 and adapted to the negative electrode 201, and the adjustment component 400 includes a flow rate sensing part 401 arranged on the top of the shell 101 and adapted to the air inlet 103, and an adjustment part 402 arranged on the inner side of the shell 101 and adapted to the negative electrode 201. In this embodiment, the flow rate sensing part 401 is a flow meter installed on one side of the air inlet 103, which can measure the amount of exhaust gas flowing into the air inlet 103 per unit time. According to the amount of exhaust gas entering per unit time, the intensity of the electric field 203 can be adjusted by the adjustment part 402. When too much exhaust gas enters per unit time, the intensity of the electric field 203 is increased, thereby maintaining the adsorption effect of the rosin.

[0047] The strength of the electric field 203 is proportional to the potential difference (i.e., voltage), and inversely proportional to the distance between the negative electrode 201 and the positive electrode 202. Generally, increasing the voltage means greater energy consumption. In this embodiment, the distance between the negative electrode 201 and the positive electrode 202 is adjusted by the amount of exhaust gas flowing per unit time measured by the flow velocity sensing unit 401, and the strength of the electric field 203 is adjusted to maintain the adsorption effect on the rosin.

[0048] Furthermore, the regulating part 402 includes a mounting frame 402a disposed inside the housing 101 and connected to both ends of the electric field 203, and an adjusting member 402b disposed on one side of the mounting frame 402a, and a gap is left between the outer wall of the mounting frame 402a and the inner wall of the housing 101. The adjusting member 402b is set up by setting the mounting frame 402a, and a gap is left between the maximum size of the outer wall of the mounting frame 402a and the positive electrode 202 on the inner wall of the housing 101, so that the melted rosin liquid can flow down and be easily collected. The minimum size of the mounting frame 402a is adapted to the maximum distance that the negative electrode 201 moves, so as to prevent the rosin waste gas from entering the gap between the mounting frame 402a and the negative electrode 201, and make the rosin waste gas always flow between the negative electrode 201 and the positive electrode 202 after passing through the mounting frame 402a.

[0049] The adjusting member 402b includes a guide groove 402b-1 disposed on one side of the mounting frame 402a, a slider 402b-2 slidably connected to one side of the guide groove 402b-1, a limit rod 402b-3 disposed on one side of the slider 402b-2, a connecting shaft 402b-4 rotatably connected to one side of the mounting frame 402a, a driving disk 402b-5 disposed on one side of the connecting shaft 402b-4, and an arc groove 402b-6 opened on one side of the driving disk 402b-5 and adapted to the limit rod 402b-3. The negative electrode 201 is disposed on one side of the slider 402b-2, and the negative electrodes 201 are distributed in a circular array and are provided in no less than three groups. The connecting shaft 402b-4 can be manually driven or electrically driven externally, generally driven by a motor, so as to realize precise adjustment of the strength of the internal electric field 203. After being driven, the rotation of the connecting shaft 402b-4 will drive the driving disk 402b-5 to rotate, and the rotation of the driving disk 402b-5 will drive each group of arc grooves 402b-6 to rotate around the connecting shaft 402b-4, and then the arc grooves 402b-6 will squeeze the limit rod 402b-3, so that the limit rod 402b-3 drives the slider 402b-2 to move along the direction of the guide groove 402b-1.

[0050] Preferably, one side of the negative electrode 201 is provided with an arc groove 201a and an arc plate 201b, respectively. The arc plate 201b of any group of negative electrodes 201 is slidably connected with the arc groove 201a of the adjacent group of negative electrodes 201, and the arc plate 201b is made of elastic conductive material. There are multiple groups of negative electrodes 201, and the structure size is the same and they are distributed in a ring array. The electrode plates of adjacent negative electrodes 201 are connected by arc plates 201b made of conductive material. The arc plate 201b has a certain bending elasticity, and is fixedly connected with one group between adjacent negative electrodes 201, and is slidably connected with the other group between adjacent negative electrodes 201, that is, the arc plate 201b and the two adjacent negative electrodes 201 can be conductive.

[0051] The rest of the structure is the same as that of Example 1.

[0052] Working principle: according to the change of the exhaust gas volume entering the air inlet 103 per unit time detected by the flow velocity sensing unit 401, the connecting shaft 402b-4 is driven to rotate, and the rotation of the connecting shaft 402b-4 will drive the driving disk 402b-5 to rotate, and the rotation of the driving disk 402b-5 will drive each group of arc grooves 402b-6 to rotate around the connecting shaft 402b-4, and then the arc grooves 402b-6 will squeeze the limiting rod 402b-3, so that the limiting rod 402b-3 drives the slider 402b-2 to move along the direction of the guide groove 402b-1, and the movement of the slider 402b-2 will drive the electrode plate of the negative electrode 201 to move away from or close to the positive electrode 202;

[0053] In the process of two adjacent negative electrodes 201 moving toward the positive electrode 202, the arc plate 201b is pulled by the fixed side of the negative electrode 201, so that the other side of the arc plate 201b slides and is pulled out along the arc groove 201a connected to the negative electrode 201; and in the process of two adjacent negative electrodes 201 moving away from the positive electrode 202, the arc plate 201b is forced to be reversely retracted into the arc groove 201a, so that each group of negative electrodes 201 is always kept connected as a whole for conductivity, and the strength of the electric field 203 is dynamically adjusted by adjusting the distance between the negative electrode 201 and the positive electrode 202 connected as a whole, so that after a large amount of high-speed rosin waste gas flows into the electric field 203, the strength of the electric field 203 is enhanced to improve the adsorption effect, thereby reducing the impact of the high-speed rosin waste gas being discharged from the outlet 104 without being thoroughly adsorbed, and maintaining the purification effect of the rosin waste gas.

[0054] Example 3

[0055] Reference Figure 6-Figure 9, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment cancels the arc plate 201b connecting adjacent groups of negative electrodes 201, and provides a barrier 402c between adjacent groups of negative electrodes 201, which evenly divides the electric field 203 into multiple groups that do not interfere with each other, and can achieve a uniform and stable adsorption effect in all directions and angles.

[0056] Specifically, a barrier 402c is provided between adjacent negative electrodes 201, and the electric field 203 formed between the negative electrode 201 and the positive electrode 202 is separated into multiple groups by the barrier 402c; the barrier 402c includes an insulating frame 402c-1 provided between the inner wall of the positive electrode 202 and the mounting frame 402a, and a conductive plate 402c-2 provided inside the insulating frame 402c-1. Adjacent negative electrodes 201 are isolated by the barrier 402c, wherein the insulating frame 402c-1 can separate the conductive plate 402c-2 from the electrodes, and the conductive plate 402c-2 can evenly separate the adjacent electric fields 203 without interfering with each other, and the independent electric field 203 formed between each group of negative electrodes 201 and the positive electrode 202 is relatively uniform, so that the effect of each group of electric fields 203 on the rosin waste gas is similar and stable.

[0057] Further, the flow velocity sensing unit 401 includes a gas collecting chamber 401a disposed inside the mounting frame 402a at the bottom and connected to the air inlet 103, a wind impeller 401b rotatably connected inside the gas collecting chamber 401a, a vent 401c disposed on one side of the mounting frame 402a and connected to the gas collecting chamber 401a, and a sensing member 401d disposed inside the mounting frame 402a and connected to the connecting shaft 402b-4. In this embodiment, the vents 401c are distributed in a circular array with the central axis of the positive electrode 202 as the center, so that the rosin waste gas discharged from the vents 401c can enter each group of electric fields 203 separated by the conductive plate 402c-2 relatively evenly.

[0058] Among them, the induction component 401d includes an adjusting motor 401d-1 installed inside the mounting frame 402a, a magnetic induction switch 401d-2 arranged inside the mounting frame 402a and adapted to the adjusting motor 401d-1, a limiting slide rail 401d-3 arranged on one side of the wind impeller 401b, a magnetic component 401d-4 slidably connected to the limiting slide rail 401d-3, and an elastic element 401d-5 connected between the magnetic component 401d-4 and the rotation center of the wind impeller 401b.

[0059] The magnetic part 401d-4 is made of magnetic material, and a metal spring is installed in the magnetic induction switch 401d-2. The metal spring is deformed due to the magnetic attraction of the magnetic part 401d-4, and the degree of deformation can be displayed by an external displacement sensor. The closer the distance between the magnetic part 401d-4 and the metal spring is, the greater the magnetic force on the metal spring is. Then, the adjustment motor 401d-1 can be controlled accordingly according to the degree of deformation of the metal spring to adjust the distance between the negative electrode 201 and the positive electrode 202.

[0060] A rotating shaft 401b-1 is provided at the rotation center of the impeller 401b, and a limiting slide rail 401d-3 is provided on the rotating shaft 401b-1. In this embodiment, the elastic element 401d-5 is a spring, and the magnetic part 401d-4 will stretch the spring displacement under the centrifugal force. The greater the spring displacement distance, the greater the elastic force. When the centrifugal force of the magnetic part 401d-4 is equal to the spring elastic force, the force will be balanced and the position will reach a relatively fixed state.

[0061] Preferably, the output end of the regulating motor 401d-1 is connected to the connecting shaft 402b-4, the magnetic induction switch 401d-2 is arc-shaped and takes the rotation center of the wind impeller 401b as the center of the circle, the limiting slide rails 401d-3 and the magnetic member 401d-4 are arranged in a circular array with no less than two groups, and the angle C1 between the two adjacent groups of limiting slide rails 401d-3 is not greater than the center angle C2 of the magnetic induction switch 401d-2, so that the limiting slide rail 401d-3 is rotated. During the movement, there is always at least one group of magnetic parts 401d-4 close to the magnetic induction switch 401d-2. When this group of magnetic parts 401d-4 gradually deviates from the magnetic induction switch 401d-2, another group of magnetic parts 401d-4 will gradually approach the magnetic induction switch 401d-2, thereby giving the magnetic induction switch 401d-2 a relatively stable magnetic induction. The magnetic induction switch 401d-2 is set to an arc shape, with the rotation center of the magnetic part 401d-4 as the center of the circle.

[0062] In this embodiment, the regulating motor 401d-1 can be automatically controlled by a built-in program, and the displacement distance of the metal spring of the magnetic induction switch 401d-2 is transmitted to the regulating motor 401d-1 through the displacement sensor. When the displacement of the metal spring of the magnetic induction switch 401d-2 increases, that is, the speed of the wind impeller 401b increases, the magnetic component 401d-4 approaches the magnetic induction switch 401d-2, and the regulating motor 401d-1 drives the connecting shaft 402b-4 to rotate in the positive direction, so that the distance between the negative electrode 201 and the positive electrode 202 is reduced, and the intensity of the electric field 203 is increased; when the displacement of the metal spring of the magnetic induction switch 401d-2 decreases, that is, the speed of the wind impeller 401b decreases, the magnetic component 401d-4 moves away from the magnetic induction switch 401d-2, and the regulating motor 401d-1 drives the connecting shaft 402b-4 to rotate in the opposite direction, so that the distance between the negative electrode 201 and the positive electrode 202 is increased, and the intensity of the electric field 203 is reduced.

[0063] When the intake volume of rosin waste gas is stable, the magnetic force of the magnetic part 401d-4 on the magnetic induction switch 401d-2 is relatively stable, but there may still be a certain amplitude of oscillation, and thus the distance between the negative electrode 201 and the positive electrode 202 will maintain a certain amplitude of oscillation change state, which can achieve mixed oscillation of the rosin waste gas in the electric field 203, further enhance the contact between the rosin waste gas and the inner wall of the electrode, thereby enhancing the purification and adsorption effect of the rosin.

[0064] The remaining structures are the same as those in Example 2.

[0065] Working principle: After entering the air inlet 103, the rosin waste gas will enter the air collecting chamber 401a. The rosin waste gas that continuously enters the air collecting chamber 401a will drive the impeller 401b to rotate. The greater the amount of rosin waste gas entering the air collecting chamber 401a per unit time, the faster the impeller 401b rotates. The rotation of the impeller 401b will discharge the rosin waste gas relatively evenly from the upper air vent 401c into the multiple groups of electric fields 203 separated by the barrier 402c. The rotation of the impeller 401b will drive each group of limit slide rails 401d-3 and the magnetic member 401 d-4 rotates around the rotation center of the wind impeller 401b, so that the magnetic part 401d-4 in the limiting slide rail 401d-3 slides outward along the limiting slide rail 401d-3 under the action of centrifugal force. While sliding in the limiting slide rail 401d-3, the magnetic part 401d-4 will stretch the elastic element 401d-5. The longer the stretching distance of the elastic element 401d-5 is, the greater the pulling force is. When the pulling force of the elastic element 401d-5 on the magnetic part 401d-4 is balanced with the centrifugal force, the position of the magnetic part 401d-4 will be relatively balanced.

[0066] Since the shapes and sizes of the limiting slide rails 401d-3 and the magnetic parts 401d-4 are the same, the distances of the magnetic parts 401d-4 from the initial state after rotation are the same, and the magnetic induction switch 401d-2 can be affected by the magnetic parts.

[0067] 401d-4 senses attraction. The closer the magnetic part 401d-4 is to the magnetic induction switch 401d-2, the greater the magnetic force sensed by the magnetic induction switch 401d-2. The magnetic induction switch 401d-2 is electrically connected to the regulating motor 401d-1. The change of the magnetic force sensed by the magnetic induction switch 401d-2 can control the driving and adjustment of the regulating motor 401d-1. The output end of the regulating motor 401d-1 is connected to the connecting shaft 402b-4. By controlling the forward or reverse rotation of the connecting shaft 402b-4, the slider 402b-2 and the electrode plate of the negative electrode 201 can be driven. Move in the direction away from or close to the positive electrode 202, thereby adjusting the distance between the negative electrode 201 and the positive electrode 202, and realizing dynamic adjustment of the intensity of the electric field 203; adjacent negative electrodes 201 are isolated by the barrier 402c, wherein the insulating frame 402c-1 can separate the conductive plate 402c-2 from the electrodes, and the conductive plate 402c-2 can evenly separate the adjacent electric fields 203 without interfering with each other, and the independent electric field 203 formed between each group of negative electrodes 201 and the positive electrode 202 is relatively uniform, so that the effect of each group of electric fields 203 on the rosin waste gas is similar and stable.
