Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to a dispensing device for monitoring the glue volume ratio and a dispensing equipment having the same. Background Technology

[0002] In modern industrial automation, dispensing technology is widely used as an important process in industries such as electronics, semiconductors, and automobiles. Automated dispensing equipment is commonly implemented using pneumatic systems. The core mechanisms of such equipment typically include key components such as cylinders, pistons, glue cartridges, and dispensing valves.

[0003] Its working principle utilizes compressed air as a power source, applying thrust to a piston in the glue cartridge via an air rod within the cylinder. Under air pressure, the piston moves within the glue cartridge, extruding and delivering the glue material to the dispensing valve. The dispensing valve, as the final actuator controlling the glue flow, is responsible for precisely applying the glue to the designated location on the workpiece. In this glue supply system, the control of the glue supply volume primarily relies on two key parameters: air pressure and dispensing time. Operators typically adjust the glue supply volume by setting the desired air pressure value and the dispensing duration through the control system.

[0004] However, this air pressure-based adhesive supply control method has inherent limitations. First, compressed air systems themselves have a certain degree of fluctuation; factors such as the operating status of the air compressor, air pressure loss in the pipeline, and changes in ambient temperature all affect the stability of the air pressure. Second, the physical properties of adhesive materials, such as viscosity and thixotropy, change with temperature and time, requiring the air pressure control system to adapt to these changes. However, in practical applications, simple air pressure control often struggles to respond quickly to these changes. These problems ultimately lead to poor repeatability of adhesive supply, with significant deviations in adhesive volume between applications under the same parameter settings. This is especially true for two adhesives that need to be mixed in a set ratio. If the ratio is not monitored in real time before mixing, large deviations in adhesive volume can easily result in a final mixing ratio outside the set range. This leads to low mixing accuracy, making it impossible to supply adhesive with ideal mixing precision and thus failing to meet the requirements of high-precision dispensing processes.

[0005] In response, the inventor of this patent, drawing on experience, deeply considered the problems encountered in his work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems.

[0074] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a glue-pushing device 1000 for monitoring glue quantity ratio.

[0075] Reference Figures 1 to 6 As shown, the glue dispensing device 1000 for monitoring glue quantity ratio according to an embodiment of the present invention includes:

[0076] Valve body 10; the valve body 10 has a valve cavity arranged vertically; an active piston 101 is provided inside the valve cavity that can slide up and down, the active piston 101 divides the valve cavity into an upper cavity 102 and a lower cavity 103, and the bottom of the active piston 101 has a first slot 1011 and a second slot 1012 arranged side by side upward;

[0077] The first magnetic sensing element 20; the first elastic sensing element is elastically floating in the vertical direction and is snapped into the first slot 1011;

[0078] The second magnetic sensing element 30; the second elastic sensing element is elastically floating in the vertical direction and is snapped into the second slot 1012;

[0079] First piston rod 40 and second piston rod 50; the first piston rod 40 and the second piston rod 50 are arranged side by side, the upper ends of which are located in the lower cavity 103 and extend into the first slot 1011 and the second slot 1012 respectively, so as to be connected to the first magnetic induction element 20 and the second magnetic induction element 30 respectively, and the lower ends of which are located outside the lower part of the valve body 10, so as to push the first adhesive and the second adhesive that need to be mixed in a preset ratio downwards respectively;

[0080] When the first piston rod 40 is subjected to an upward counter-force greater than a preset value, its upper end will push the first magnetic induction element 20 upward, so that the first magnetic induction element 20 will elastically float upward along the first slot 1011; when the second piston rod 50 is subjected to an upward counter-force greater than a preset value, its upper end will push the second magnetic induction element 30 upward, so that the second magnetic induction element 30 will elastically float upward along the second slot 1012.

[0081] A first magnetostrictive displacement sensor 60 and a second magnetostrictive displacement sensor 70 are arranged side by side outside the valve body 10 and extend along the vertical direction of the valve body 10 to detect the vertical displacement of the first magnetic induction element 20 and the vertical displacement of the second magnetic induction element 30.

[0082] Based on the above, it is clear that in specific implementation, this application is mainly used as a glue-pushing device 1000 for monitoring the glue quantity ratio.

[0083] Specifically, when applying this application, when the active piston 101 moves downward along the valve cavity under air pressure, the first piston rod 40 and the second piston rod 50 will move downward accordingly, thereby using their lower ends to push the first and second adhesives in the configured adhesive supply device downward to complete their quantitative output according to a preset ratio for mixing. In this process, since this application is provided with the first magnetic induction element 20, the second magnetic induction element 30, the first magnetostrictive displacement sensor 60 and the second magnetostrictive displacement sensor 70, the first magnetostrictive displacement sensor 60 is used to detect the vertical displacement of the first magnetic induction element 20, and the second magnetostrictive displacement sensor 70 is used to detect the vertical displacement of the second magnetic induction element 30.

[0084] Thus, when the first piston rod 40 is subjected to an upward counter-force greater than a preset value, its upper end will push the first magnetic induction element 20 upward, so that the first magnetic induction element 20 will elastically float upward along the first slot 1011; similarly, when the second piston rod 50 is subjected to an upward counter-force greater than a preset value, its upper end will also push the second magnetic induction element 30 upward, so that the second magnetic induction element 30 will elastically float upward along the second slot 1012.

[0085] Furthermore, each time the active piston 101 is driven to move the first piston rod 40 and the second piston rod 50 downward by a predetermined displacement, so as to use the lower ends of the first piston rod 40 and the second piston rod 50 to push the first and second adhesives in the configured adhesive supply device downward to complete their quantitative output according to a predetermined ratio, it can be clearly understood that:

[0086] On the one hand, if the upward counterforce on the first piston rod 40 is greater than the preset value, its upper end will push the first magnetic induction element 20 upward, so that the first magnetic induction element 20 elastically floats upward along the first slot 1011. When the difference between its total downward displacement and the preset displacement is greater than the set value, it indicates that the amount of the first adhesive pushed downward is less than the set amount. At this time, when the first magnetostrictive displacement sensor 60 converts the detected data of the vertical displacement change of the first magnetic induction element 20 into an electrical signal output, an alarm can be output through the equipped alarm. At this time, the operator can know that the amount of the first adhesive pushed downward is less than the set ratio and needs to stop work to check the reason for the amount of the first adhesive pushed downward. For example, it may be that the viscosity of the adhesive supply device has increased, the state has become dry, or the active piston 101 described in this application has deformed, etc., until the real reason is found, the application can be used again.

[0087] On the other hand, if the upward counterforce on the second piston rod 50 is greater than the preset value, its upper end will push the second magnetic induction element 30 upward, so that the second magnetic induction element 30 elastically floats upward along the second slot 1012. When the difference between its total downward displacement and the preset displacement is greater than the set value, it indicates that the amount of the second adhesive pushed downward is less than the set amount. At this time, when the second magnetostrictive displacement sensor 70 converts the detected vertical displacement change data of the second magnetic induction element 30 into an electrical signal output, an alarm can also be output through the equipped alarm. At this time, the operator can know that the amount of the second adhesive pushed downward is less than the set ratio and needs to stop work to check the reason for the amount of the second adhesive pushed downward. It may be that the viscosity of the adhesive supply device has increased, the state has become dry, or the active piston 101 described in this application has deformed, etc., until the real reason is found, the application can be used again.

[0088] Furthermore, through the aforementioned optimized design, this application is highly practical. It can be used to monitor the proportion of the extruded adhesive in real time. When the proportion of the adhesive is abnormal, the equipped alarm will output an alarm to remind the operator to stop the machine for inspection in time. In this way, this application can ensure the accuracy of the proportion of the extruded adhesive during use, so as to ensure high mixing accuracy in the subsequent process, and ultimately supply adhesive with ideal mixing accuracy to meet the requirements of high-precision dispensing process.

[0089] Furthermore, in specific implementation, in accordance with... Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, according to one embodiment of the present invention, the first magnetic induction element 20 includes a first connector 201, a first spring 202 and a first permanent magnet 203;

[0090] The first slot 1011 is formed in a cross shape, including a first vertical slot 1011a and a first horizontal slot 1011b that is connected to the middle of the first vertical slot 1011a; the upper end of the first piston rod 40 is movable up and down and is fitted in the lower part of the first vertical slot 1011a with an interference fit, and its top is provided with a first connector 401.

[0091] Based on this, the first connector 201 of this application has a first sleeve hole (not shown) in the middle part, which is sleeved to the lower part of the first connector 401, and the first connector 201 is limited in the first transverse groove 1011b, and can float up and down in the first transverse groove 1011b.

[0092] Based on this, the lower end of the first spring 202 is sleeved on the upper part of the first connector 401 and elastically abuts against the upper end surface of the first connector 201, while its upper end elastically abuts against the top of the first vertical groove 1011a.

[0093] Furthermore, the first permanent magnet 203 of this application is embedded in the first connector 201.

[0094] Therefore, it can be clearly understood that in the initial state, the lower end of the first spring 202 elastically abuts against the upper end surface of the first connector 201, and its upper end elastically abuts against the top of the first vertical groove 1011a, so that the whole is in a compressed state. At this time, the corresponding first connector 201 with the first permanent magnet 203 embedded inside will be in the lowest position of the first horizontal groove 1011b.

[0095] When this application is used to move the active piston 101 downward along the valve cavity under air pressure, the first piston rod 40 and the corresponding first connector 201 with the first permanent magnet 203 embedded inside will move downward accordingly. Thus, the lower end of the first piston rod 40 can be used to push the first adhesive in the configured adhesive supply device downward. When the first piston rod 40 is subjected to an upward counter-force from the first adhesive that is greater than a preset value, its upper end will push the first spring 202 upward, causing the first spring 202 to be further compressed. At this time, the first permanent magnet 203 will float upward along the first slot 1011.

[0096] Furthermore, when the first magnetic induction element 20 of this application includes the first connector 201, the first spring 202, and the first permanent magnet 203 with the structure described above, and is equipped with the first piston rod 40 with the first connector 401, the first permanent magnet 203 of this application can float elastically in the vertical direction in a stable manner, making the first magnetic induction element 20 of this application reliable in use.

[0097] Preferably, in this technical solution, according to an embodiment of the present utility model, the outer wall of the first connector 201 has a first mounting hole 2011 that is horizontally opposite to the first magnetostrictive displacement sensor 60, and the first permanent magnet 203 is embedded in the first mounting hole 2011.

[0098] Based on this, the lower outer wall of the active piston 101 described in this application has a first port 1013 that connects to one end of the first transverse groove 1011b. The first port 1013 is located in the transverse direction between the first magnetostrictive displacement sensor 60 and the first mounting hole 2011.

[0099] Therefore, it can be clearly understood that in the actual application of this application, the first permanent magnet 203 is embedded in the first mounting hole 2011, which makes it well protected and not easily worn by the inner wall of the valve body 10, thus ensuring its magnetic stability. At the same time, it also ensures that the first magnetostrictive displacement sensor 60 and the first permanent magnet 203 are separated only by the valve body 10 and are not blocked by the active piston 101 and the first connecting member 201, thereby improving the accuracy of the first magnetostrictive displacement sensor 60 in detecting the position of the first permanent magnet 203.

[0100] Furthermore, in the specific implementation, we will continue to refer to... Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the second magnetic induction element 30 includes a second connector 301, a second spring 302, and a second permanent magnet 303;

[0101] The second slot 1012 is formed into a cross shape, including a second vertical slot 1012a and a second horizontal slot 1012b that is connected to the middle of the second vertical slot 1012a; the upper end of the second piston rod 50 is movable up and down and is fitted into the lower part of the second vertical slot 1012a with an interference fit, and its top is provided with a second connector 501.

[0102] Based on this, the second connector 301 of this application has a second sleeve hole (not shown) in the middle part, which is sleeved to the lower part of the second connector 501, and the second connector 301 is limited in the second transverse groove 1012b and can float up and down in the second transverse groove 1012b;

[0103] Based on this, the lower end of the second spring 302 is sleeved on the upper part of the second connector 501, and the upper end elastically abuts against the top of the second vertical groove 1012a.

[0104] Furthermore, the second permanent magnet 303 of this application is embedded in the second connector 301.

[0105] Therefore, it can be clearly seen that in the initial state, the lower end of the second spring 302 elastically abuts against the upper end surface of the second connector 301, and its upper end elastically abuts against the top of the second vertical groove 1012a, so that the whole is in a compressed state. At this time, the corresponding second connector 301 with the second permanent magnet 303 embedded inside will be in the lowest position of the second horizontal groove 1012b.

[0106] When this application is used to move the active piston 101 downward along the valve cavity under air pressure, the second piston rod 50 and the corresponding second connector 301 with the second permanent magnet 303 embedded inside will move downward accordingly. Thus, the lower end of the second piston rod 50 can be used to push the second adhesive in the configured adhesive supply device downward. When the upward counter-force of the second adhesive on the second piston rod 50 is greater than a preset value, its upper end will push the second spring 302 upward, causing the second spring 302 to be further compressed. At this time, the second permanent magnet 303 will float upward along the second slot 1012.

[0107] Furthermore, when the second magnetic induction element 30 of this application includes the second connector 301, the second spring 302 and the second permanent magnet 303 with the structure described above, and is equipped with the second piston rod 50 with the second connector 501, the second permanent magnet 303 of this application can float elastically in the up and down direction in a stable manner, so that the second magnetic induction element 30 of this application can be used reliably.

[0108] Preferably, in this technical solution, according to an embodiment of the present utility model, the outer wall of the second connector 301 has a second mounting hole 3011 that is horizontally opposite to the second magnetostrictive displacement sensor 70, and the second permanent magnet 303 is embedded in the second mounting hole 3011.

[0109] Based on this, the lower outer wall of the active piston 101 described in this application is also provided with a second port 1014 that connects to one end of the second transverse groove 1012b. The second port 1014 is located in the transverse direction between the second magnetostrictive displacement sensor 70 and the second mounting hole 3011.

[0110] Therefore, it can be clearly understood that in the actual application of this application, the second permanent magnet 303 is embedded in the second mounting hole 3011, which makes it well protected and not easily worn by the inner wall of the valve body 10, thus ensuring its magnetic stability. At the same time, it also ensures that the second magnetostrictive displacement sensor 70 and the second permanent magnet 303 are only separated by the valve body 10 and are not blocked by the active piston 101 and the second connecting member 301, which can improve the accuracy of the second magnetostrictive displacement sensor 70 in detecting the position of the second permanent magnet 303.

[0111] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0112] Furthermore, in specific implementation, in accordance with Figure 1 and Figure 2 As shown, according to an embodiment of the present utility model, the upper end of the valve body 10 is provided with a first air port 104 communicating with the upper part of the upper cavity 102, and the lower end is provided with a second air port 105 communicating with the lower part of the lower cavity 103. The bottom of the valve body 10 is provided with a first passage 106 and a second passage 107 communicating with the lower cavity 103.

[0113] Based on this, in this application, comparison Figure 3 , Figure 5 and Figure 6 As shown, the lower ends of the first piston rod 40 and the second piston rod 50 extend downward from the first through-hole 106 and the second through-hole 107 respectively; a first sealing ring 108 is fixedly provided on the inner wall of the first through-hole 106, which tightly abuts against the outer wall of the first piston rod 40; a second sealing ring 109 is fixedly provided on the inner wall of the second through-hole 107, which tightly abuts against the outer wall of the second piston rod 50.

[0114] Therefore, it can be clearly stated that:

[0115] On the one hand, when compressed air enters the upper cavity 102 through the first air port 104, it will push the active piston 101 downward to push the first adhesive and the second adhesive that need to be mixed in a preset ratio downward, and the mixing ratio between the first adhesive and the second adhesive can be monitored in real time during the pushing process; on the other hand, when compressed air enters the lower cavity 103 through the second air port 105, it will push the active piston 101 upward to reset it to the initial state for easy reuse of this application.

[0116] On the other hand, by setting the first sealing ring 108 and the second sealing ring 109, the sealing of the lower cavity 103 is maintained, and the first passage 106 and the second passage 107 of the lower cavity 103 have a good air leakage prevention effect.

[0117] Furthermore, in specific implementation, we will continue to refer to... Figure 3 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, this application also includes a glue cartridge 80 for holding the adhesive liquid:

[0118] The glue cylinder 80 has a first glue cavity 801 for storing a first glue liquid with a set amount ratio and a second glue cavity 802 for storing a second glue liquid with a set amount ratio, arranged vertically side by side. The set amount ratio of the first glue liquid and the second glue liquid can be achieved by designing the first glue cavity 801 and the second glue cavity 802 with different inner diameters. A first driven piston 803 is provided inside the first glue cavity 801 that can slide up and down. A second driven piston 804 is provided inside the second glue cavity 802 that can slide up and down.

[0119] Furthermore, the top of the rubber sleeve 80 is detachably connected to the bottom of the valve body 10, and the top of the rubber sleeve 80 has a first piston port 805 facing the first through port 106 and a second piston port 806 facing the second through port 107; the lower end of the first piston rod 40 extends into the first rubber cavity 801 through the first piston port 805 and is connected to the first driven piston 803; the lower end of the second piston rod 50 extends into the second rubber cavity 802 through the second piston port 806 and is connected to the second driven piston 804.

[0120] Furthermore, the bottom of the glue tube 80 has a first glue outlet 807 that connects to the lower part of the first glue cavity 801 and a second glue outlet 808 that connects to the lower part of the second glue cavity 802.

[0121] Therefore, it can be clearly stated that this application is a glue cylinder 80 with its own adhesive container, so that when the first piston rod 40 and the second piston rod 50 are driven to move downward, the lower ends of the piston rods can be used to push the first glue cavity 801 of the glue cylinder 80 and the second glue cavity 802 of the glue cylinder 80 downward to complete the quantitative output according to the preset ratio.

[0122] Furthermore, in specific implementation, it is still necessary to refer to... Figure 3 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, this application also includes a mixing tube 90 for mixing adhesives;

[0123] The upper end of the mixing tube 90 is connected to the first glue outlet 807 and the second glue outlet 808, and the lower end has a glue outlet hole 901.

[0124] Therefore, it can be clearly stated that this application has a built-in mixing tube 90 for mixing adhesives. When the first piston rod 40 and the second piston rod 50 are driven to move downward, their lower ends can be used to push the first adhesive liquid in the first adhesive cavity 801 of the adhesive cylinder 80 and the second adhesive liquid in the second adhesive cavity 802 of the adhesive cylinder 80 downward to complete the quantitative output according to the preset ratio. The adhesive liquid flows into the mixing tube 90 for uniform mixing, so that it is finally discharged from the adhesive outlet 901 at the lower end of the mixing tube 90. At this time, it can be directly used to apply adhesive to the preset dispensing position on the surface of the product that needs to be glued.

[0125] It should be added that, in specific implementation, comparison should be made with... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, this application also includes a locking seat 100;

[0126] The locking seat 100 is closable and can be locked between the top of the rubber sleeve 80 and the bottom of the valve body 10.

[0127] Therefore, opening the locking seat 100 facilitates the disassembly of the valve body 10 and the glue cylinder 80. As for the specific structure of the locking seat 100, it is common in the prior art. For example, the hollow fastener set in the utility model patent "Two-component dispensing device" with patent number "202322981574.9" filed by the patent applicant is basically the same in structure and working principle. Therefore, the specific structure of the locking seat 100 in this patent solution will not be described in detail here.

[0128] Furthermore, it is necessary to add that, in specific implementation, comparison should be made with... Figure 3 , Figure 4 and Figure 5 As shown, according to one embodiment of the present invention, the active piston 101 may include a lower piston and an upper piston that are stacked and fixed together by fasteners such as fastening bolts, so as to provide a first slot 1011 and a second slot 1012 that can be laterally cut in the middle, so as to facilitate the corresponding insertion and placement of the first connector 201 and the second connector 301 therein.
