Technical Field

[0001] The invention belongs to the technical field of perfusion equipment, and in particular relates to a dual-channel automatic perfusion device. Background Art

[0002] The glue pouring equipment is an automated device specially used to pour glue into a specific mold or workpiece accurately and efficiently. Under the command of the control system, the vacuum pump extracts the glue from the glue storage tank and transports it to the pouring head through a pipeline. The motion mechanism drives the pouring head to move to the specified position according to the preset path and parameters, and then pours the glue into the mold or workpiece evenly and quantitatively. In the prior art, the overall positioning is achieved by programming and visual positioning to achieve the outlet positioning effect. If the input data is missing or for other reasons, the positioning accuracy may be reduced. Different lighting conditions may cause changes in visual features, which will also affect the accuracy of the positioning effect. In addition, most glue pouring equipment only pours a single component of glue, does not have the function of extracting and mixing different components of glue, and lacks the adjustment of the pouring parameters of different components of glue. Summary of the invention

[0003] The present invention aims to provide a dual-channel automatic perfusion device to solve the deficiencies in the prior art.

During the positioning of the positioning mechanism body, the control system controls the glue supply system and the glue mixing valve body to complete the overall filling action; The main body of the mixing valve includes two dispensing valves, a panel, an input hose, a rubber cavity, a rubber mixing tube, a rubber mixing tube connection port, two connection ports, two cleaning ports and two air inlet ports. The connection ports, cleaning ports and air inlet ports are all connected to the input hose, the bottom of the input hose is connected to the rubber cavity, and a rubber mixing tube is arranged below the rubber cavity; The main body of the positioning mechanism includes an XY axis for controlling the main body of the glue mixing valve to move longitudinally and transversely along the pouring direction, a Z axis for controlling the main body of the glue mixing valve to move vertically, a servo motor, a driving shaft, a bottom plate, a residual glue collection container arranged on the bottom plate, and a positioning mold, wherein the positioning mold is used to fix the workpiece to be poured; The glue supply system comprises a first glue storage barrel, a feeding pipe, a second glue storage barrel and a weight sensor, and the weight sensor is electrically connected to the control system.

[0005] Preferably, the main body of the positioning mechanism also includes a height measuring sensor, a positioning sensor and a product positioning confirmation detection photoelectric. The height measuring sensor is used to measure the filling height of the mixing valve body and feed back to the control system. The positioning sensor is used to detect whether the workpiece to be filled on the positioning mold has reached the specified filling position. The product positioning confirmation detection photoelectric is used to determine whether the rubber output port of the rubber mixing tube has reached the specified filling position.

[0006] Preferably, the rubber mixing tube is a dynamic rubber mixing tube.

[0007] Preferably, the glue mixing valve body further comprises a regulating valve, and the regulating valve is used to adjust the pressure of the air inlet port.

[0008] Preferably, the servo motor is used to provide power drive, and the drive shaft is used for power transmission.

[0009] Preferably, the cleaning port is cleaned by injecting a cleaning solvent, and the discharged residual glue is collected by a residual glue collection container.

[0011] Preferably, the air inlet port is connected to an external air source device.

[0012] Preferably, the dispensing valve is used to control the flow rate and mixing ratio of the glue entering the connecting port.

[0013] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art: 1) Through the setting of the main body of the positioning mechanism, when the workpiece to be poured is placed in the positioning fixture, the positioning sensor recognizes it and detects whether the workpiece is installed in place. When the XY axis moves longitudinally and transversely to reach the specified pouring area, the Z axis controls the vertical movement of the main body of the mixing valve, which mainly adjusts the height. The height sensor determines that the discharge port has reached the pouring position. Through the product positioning confirmation detection photoelectricity ensures that the bottom of the rubber mixing tube can flow down along the side wall of the pouring workpiece, preventing the suspended glue from entering the product and bringing in air, avoiding bubbles during the injection process; 2) Two different adhesives are mixed in proportion, and the dispensing valve and regulating valve are used to adjust the adhesive filling volume and pressure. The filling parameters of each channel can be adjusted individually according to different production needs to ensure the smooth mixing of the subsequent two-component adhesive. The adhesive mixing tube adopts a dynamic mixing tube to ensure that the adhesive is mixed and stirred again after the mixing valve discharges the adhesive to ensure that the two components are mixed evenly; 3) By controlling the air pressure entering the air inlet port through the regulating valve, that is, adjusting the air pressure entering the input hose, the rubber cavity and the rubber mixing tube channel, the residual rubber in the input hose, the rubber cavity and the rubber mixing tube channel can be initially emptied, and the subsequent air pressure pushes the cleaning solvent to effectively clean the position where the rubber flows, and finally discharges it into the residual rubber collection container. The cleaning method of combining air pressure and solvent can remove the residual colloid and ensure the normal operation of the device; 4) According to the different characteristics of the two rubber materials, corresponding rubber material storage barrels are set up to ensure the performance stability of the two rubber materials and avoid performance deviations after subsequent mixing and pouring.

DETAILED DESCRIPTION

[0016] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative and are not intended to limit the scope of the present invention.

[0017] As attached Figure 1-4As shown, a dual-channel automatic filling device includes: a glue mixing valve body 100, a positioning mechanism body 200, a glue supply system 300 and a control system 400, wherein the glue mixing valve body 100 is arranged on the positioning mechanism body 200, and the control system 400 is electrically connected with the glue mixing valve body 100, the positioning mechanism body 200 and the glue supply system 300. During the positioning of the positioning mechanism body 200, the control system 400 controls the glue supply system 300 and the glue mixing valve body 100 to complete the overall filling action; The mixing valve body 100 includes two dispensing valves 104, a panel 105, an input hose 106, a rubber cavity 101, a rubber mixing tube 102, a rubber mixing tube connection port 103, two connection ports 107, two cleaning ports 108 and two air inlet ports 109, wherein the connection ports 107, the cleaning ports 108 and the air inlet ports 109 are all connected to the input hose 106, the bottom of the input hose 106 is connected to the rubber cavity 101, a rubber mixing tube 102 is arranged below the rubber cavity 101, a rubber mixing tube connection port 103 is arranged between the bottom of the rubber cavity 101 and the rubber mixing tube 102, and the arrangement of the rubber mixing tube connection port 103 facilitates the replacement and disassembly of the rubber mixing tube 102, wherein the input hose 106 is built inside the panel 105, and the connection port 107, the cleaning port 108 and the air inlet port 109 are all arranged on the panel 105; The positioning mechanism body 200 includes an XY axis 205 for controlling the mixing valve body 100 to move longitudinally and transversely along the pouring direction, a Z axis 208 for controlling the mixing valve body 100 to move vertically, a servo motor 206, a driving shaft 207, a bottom plate 209, a residual glue collection container 210 disposed on the bottom plate 209, and a positioning mold 204. The positioning mold 204 is used to fix the workpiece to be poured, that is, a corresponding card slot can be provided on the positioning mold 204 to facilitate the card connection and fixation of the workpiece to be poured, so as to ensure the stability of the workpiece to be poured; The glue supply system 300 includes a glue storage barrel 1 301, a feeding pipe 302, a glue storage barrel 2 303 and a weight sensor 304. The weight sensor 304 is electrically connected to the control system 400. The glue storage barrel 1 301 and the glue storage barrel 2 303 are respectively connected to corresponding feeding pipes 302. Through the control of the control system 400, the glue in the glue storage barrel 1 301 and the glue storage barrel 2 303 is transmitted to the connection port 107 through the feeding pipe 302. The feeding pipe 302 is an air-driven air pipe, so that the glue can quickly enter the glue mixing valve body 100. The glue supply system 300 is designed separately from the glue mixing valve body 100 and the positioning mechanism body 200, which is convenient for adding and storing glue.

[0018] When the weight sensors 304 at the bottom of the rubber storage barrel 1 301 and the rubber storage barrel 2 303 detect that the weight in the barrel reaches the lower limit, the weight sensors 304 feed back the information to the control system 400, and the control system 400 issues an alarm.

[0019] Specifically, the positioning mechanism body 200 also includes a height sensor 201, a positioning sensor 203 and a product positioning confirmation detection photoelectric 202. The height sensor 201 is used to measure the filling height of the mixing valve body 100 and feed back to the control system 400, so as to better ensure that the bottom of the rubber mixing tube 102 is at the specified filling height. The positioning sensor 203 is used to detect whether the workpiece to be poured on the positioning mold 204 has reached the specified filling position, that is, to detect whether the workpiece to be poured is installed in place. The product positioning confirmation detection photoelectric 202 is used to determine whether the rubber output port of the rubber mixing tube 102 has reached the specified filling position. Through the setting of the product positioning confirmation detection photoelectric 202, it is ensured that the workpiece to be poured is located at the bottom of the rubber mixing tube 102, and the bottom of the rubber mixing tube 102 can flow downward along the wall to prevent the suspended glue from entering the workpiece and bringing in air, thereby avoiding bubbles during the injection process.

[0020] Specifically, the rubber mixing tube 102 is a dynamic rubber mixing tube, which ensures that after the rubber is mixed and discharged through the rubber input tube 106 and the rubber cavity 101, it is mixed and stirred again in the rubber mixing tube 102, i.e., the dynamic rubber mixing tube.

[0021] Specifically, the mixing valve body 100 also includes a regulating valve 110, which is used to adjust the pressure of the air inlet port 109 so as to better control the air pressure entering the air inlet port 109. When the rubber enters the input hose 106, the regulating valve 110 adjusts the air pressure entering the input hose 106, the rubber cavity 101 and the rubber mixing tube 102 channel, thereby adjusting the rubber infusion pressure to better perform the infusion action.

[0022] Specifically, the servo motor 206 is used to provide power drive, and the drive shaft 207 is used for power transmission, that is, a servo motor 206 and a drive shaft 207 are provided at one end of the XY axis 205 and the Z axis 208, and the servo motor 206 and the drive shaft 207 provide power drive for position adjustment of the mixing valve body 100.

[0023] Specifically, the cleaning port 108 is cleaned by injecting a cleaning solvent, and after the cleaning solvent sequentially passes through the rubber input hose 106 , the rubber cavity 101 and the rubber mixing tube 102 to achieve a cleaning effect, the residual rubber discharged is collected by the residual rubber collection container 210 .

[0024] Specifically, the first rubber storage barrel 301 and the second rubber storage barrel 303 are connected to the connection port 107 of the rubber mixing valve body 100 through the feeding pipe 302. The first rubber storage barrel 301 can be used to store the rubber component I, and the second rubber storage barrel 303 can be used to store the rubber component P, so as to ensure that the two rubbers will not deteriorate in the storage barrels and cause performance deviation after mixing and pouring. In addition, according to the different characteristics of the two rubbers, for example, the protection of the I component is achieved by filling with nitrogen, and the protection of the P component is achieved by drying the air with a drying core, so as to ensure the performance stability of the two rubbers.

[0025] Specifically, the air inlet port 109 is connected to an external air source device, which provides a high-pressure air source. When the cleaning solvent is not introduced, the air pressure input by the air inlet port 109 can preliminarily clean and empty the residual rubber in the input hose 106, the rubber cavity 101 and the rubber mixing tube 102. When the cleaning solvent passes through the input hose 106, the rubber cavity 101 and the rubber mixing tube 102 in turn, it can cooperate with the cleaning solvent, that is, the cleaning solvent is pushed by the air pressure to effectively clean the position where the residual rubber is still flowing, and finally discharged into the residual rubber collection container 210.

[0026] Specifically, the dispensing valve 104 is used to control the flow rate and mixing ratio of the rubber entering the connection port 107. Through the setting of the dispensing valve 104, two rubbers can be extracted at the same time to ensure that the amount of rubber injected for each product is accurate and consistent. The injection parameters of each channel can also be adjusted separately according to different production requirements. The valve core inside the dispensing valve 104 is used to control the flow rate and mixing ratio of the fluid, so that the subsequent dynamic mixing of the two-component rubber can proceed smoothly. The sealing member inside the dispensing valve 104 ensures that the rubber entering the connection port 107 does not leak.

[0027] The specific working principle of the present invention is: Before starting the injection, the control system 400 will perform initialization settings, including checking parameters such as the status of each component and ensuring that the supply of rubber is sufficient. The workpiece to be injected is clamped and fixed in the positioning mold 204. When the injection operation is started, the main body 100 of the mixing valve is driven by the main body 200 of the positioning mechanism, and the rubber mixing tube 102 is accurately moved to the specified injection area. This movement process uses the servo motor 206 to provide power drive, the drive shaft 207 is responsible for power transmission, and the XY axis 205 is controlled to achieve precise positioning.

[0028] The filling height of the mixing valve body 100 is measured by the height measuring sensor 201 and fed back to the control system 400 to better ensure that the bottom of the rubber mixing tube 102 is at the specified filling height. The positioning sensor 203 then detects whether the workpiece to be poured on the positioning mold 204 reaches the specified filling position, that is, whether the workpiece to be poured is installed in place.

[0029] When the rubber mixing tube 102 reaches the designated area, the rubber mixing valve body 100 is driven by the Z-axis 208 to start moving downward, gradually approaching a distance above the workpiece to be poured, and the product positioning confirmation detection photoelectric 202 determines whether the rubber output port of the rubber mixing tube 102 has reached the designated pouring position, ensuring that the workpiece to be poured is located at the bottom of the rubber mixing tube 102, and the bottom of the rubber mixing tube 102 can flow downward along the wall to prevent glue from being discharged in the air, thereby avoiding affecting the quality of the subsequent poured workpiece.

[0030] Then, according to the preset injection speed, injection volume and pressure, the dispensing valve 104 and the regulating valve 110 are adjusted, and the control system 400 starts the injection action. The rubber material is fully mixed through the input hose 106, the rubber cavity 101 and the rubber mixing tube 102 in turn, and then stably injected into the injection target area.

[0031] After completing a single injection, the main body 100 of the mixing valve is driven by the Z axis 208 to move upward, leaving the current injection position, and moving to the next designated injection target area. After completing the staged injection task, the control system 400 starts the self-cleaning function, that is, the air pressure input from the air inlet port 109 can preliminarily clean and empty the residual rubber in the input hose 106, the rubber cavity 101 and the rubber mixing tube 102, and then inject the cleaning solvent through the cleaning port 108. When the cleaning solvent passes through the input hose 106, the rubber cavity 101 and the rubber mixing tube 102 in turn, it cooperates with the air pressure input from the air inlet port 109 again, that is, the cleaning solvent is pushed by the air pressure to effectively clean the position where the residual rubber is still flowing, and finally discharged into the residual rubber collection container 210, to ensure that the rubber pipeline is clean and unblocked during subsequent injection.

[0032] The above description is only a preferred implementation manner of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention should be included in the protection scope of the present invention.
