Description

Technical Field

[0001] The invention belongs to the field of automation technology, relates to the automation technology of packaging box assembly, and in particular to an automatic soldering machine for bullet packaging boxes. Background Art

[0002] At present, the production of packaging boxes has been largely automated, but generally only a few processes are used to simplify production, and there are relatively few that can integrate multiple processes. This will increase the floor space of the factory, reduce the efficiency of labor production, and increase the consumption of manpower and material resources. When it comes to the production process of bullet packaging boxes that require tight sealing, most manufacturers will choose manual operation, which increases the production time. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides an automatic soldering machine for bullet packaging boxes, which can realize many functions such as automatic loading of steel plates and baffles, gluing, high-temperature welding, and material translation. The automatic soldering machine is fully automated, and can achieve reliable solder paste welding and high-speed welding.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] An automatic soldering machine for bullet packaging boxes includes a material translation system 1, a steel plate conveying and feeding system 2, a baffle feeding and gluing system 3, a high-temperature welding system 4, an operating box 5, an operating table 6, and an electric control box 7. The material translation system 1 is fixedly installed on the operating table 6, the steel plate conveying and feeding system 2 is on one side of the operating table 6, the baffle feeding and gluing system 3 and the high-temperature welding system 4 are installed on the operating table 6, and the vibration table of the baffle feeding and gluing system is installed on the side of the operating table 6.

[0006] The material translation system 1 includes a translation mechanism 1-1, a steel plate 1-2, and a steel plate positioning assembly 1-3. The bottom of the material translation system 1 is a steel plate positioning assembly 1-3 fixed on the operating table 6. The four cantilever beams in the translation mechanism 1-1 are fixedly connected to the slider of the guide rail. There is a ball screw inside the guide rail. During the operation, the working principle of the ball screw rotation drives the slider to move horizontally, that is, the four cantilever beams fixed on the slider are driven to move horizontally. A cylinder support is fixed to the middle and tail of each cantilever beam, and the support is connected to the cylinder. The cylinder is connected to the long aluminum profile. There are two electromagnets at both ends of the aluminum profile, which play the role of adsorbing the steel plate in the process of transporting the steel plate. The telescopic movement of the cylinder drives the steel plate to move up and down.

[0007] The steel plate handling and feeding system 2 includes a lifting mechanism 2-1, a trolley 2-2, and a steel plate handling mechanism 2-3. The steel plate handling mechanism 2-3 of the steel plate handling and feeding system 2 is fixed on the operating table 6, wherein the cantilever beam mechanism is connected to the guide rail by a slider, and also works on the principle of converting the rotation of the ball screw into the translation of the slider, so that the cantilever beam translates back and forth between the upper part of the trolley and the first station on the right side of the steel plate positioning assembly on the operating table (defined as station 1). The trolley 2-2 of the steel plate handling and feeding system 2 is fixed to one side of the operating table 6 by the trolley clamping mechanism, and the material steel plate is placed on the trolley 2-2. The lifting mechanism 2-1 is at the bottom of the trolley 2-2, dragging the material steel plate in the trolley 2-2, and can support the material steel plate to move up and down.

[0008] The baffle feeding and gluing system 3 includes a gluing mechanism 3-1, a feeding mechanism 3-2, and a vibration table 3-3. The vibration table 3-3 of the baffle feeding and gluing system 3 is fixedly installed on one side of the operating table 6 by components such as a vibration table bracket, and the feeding mechanism 3-2 is connected to the vibration table 3-3 through a material channel. The feeding mechanism 3-2 and the gluing mechanism 3-1 are installed on the operating table 6. The feeding mechanism 3-2 includes components such as a servo motor, a moving device, a sensor, a cylinder, and a suction cup. The gluing mechanism 3-1 includes components such as a servo motor, a moving device, a cylinder, a glue barrel fixture, a glue barrel, and glue (solder paste) in the glue barrel. The gluing mechanism and the feeding mechanism are connected to the slider on the moving device through two cylinder supports. During the working process, the gluing mechanism and the feeding mechanism work without interfering with each other and cooperate with each other.

[0009] The high temperature welding system 4 comprises a welding head 4-1, a capillary tube 4-2, and a moving mechanism 4-3. The welding head 4-1 in the high temperature welding system 4 is mounted on the moving mechanism 4-3 and can move up and down with the moving mechanism. There are two capillary tubes 4-2, which are mounted on both sides of the welding head 4-1. Tin flows into the groove of the steel plate to be welded through the capillary tubes. The moving mechanism 4-3 is mounted on the operating table 6 through the solder plate.

[0010] The working process of an automatic soldering machine for bullet packaging boxes is as follows:

[0011] Assume that the length direction of the steel plate on the steel plate positioning assembly 1-3 on the operating table 6 is the x direction, and the width direction is the y direction. The steel plate positioning assembly 1-3 has a total of five workstations for placing steel plates. The first workstation for placing steel plates on the side of the material cart 2-2 of the operating table 6 is assumed to be workstation 1, and along the y direction are workstations 2, 3, 4, and 5 respectively.

[0012] First, the steel plate handling and feeding system 2 works. During the process of handling steel plates, the handling and feeding system is powered by the electric control box 7, the servo motor works, and the lifting mechanism 2-1 works. The material cart filled with materials (steel plates) lifts the material steel plates under the action of the lifting mechanism 2-1. When the top steel plate rises to the point where it is recognized by the sensor in the limiting device, the system detects the steel plate, and the steel plate handling mechanism 2-3 works. The cantilever beam moves. With the cooperation of the cylinder, suction cup and other components, the suction cup sucks the steel plate and lifts the steel plate from the material cart. The movement of the slider causes the steel plate sucked by the suction cup on the cantilever beam to be sent to the workstation 1. Then the baffle feeding and gluing system 3 works to carry out the next step of processing on the steel plate. After the baffle feeding and gluing system 3 works for one cycle, the material translation system 1 works. At this time, the steel plate at workstation 1 that has completed the gluing and baffle feeding processes is transported to workstation 2 under the action of the material translation system 1. At this time, the steel plate handling and feeding system 2 works again, and carries the second steel plate to the work station 1, and repeats the above working process. After carrying the steel plates five times, the lifting mechanism 2-1 of the steel plate handling and feeding system 2 works, and drags the steel plate on the material cart 2-2 to rise by 5mm (the height of five steel plate thicknesses). When the top steel plate is recognized by the sensor on the limit device, the above working process is repeated. During the lifting process, when the lifting mechanism 2-1 drags the steel plate up by 5mm, the sensor in the limit device does not recognize the steel plate, and the system recognizes it as a lack of material state. At this time, the system alarms to remind you to replenish the material.

[0013] Next, the process of gluing the baffle is carried out. During the gluing process, the solder paste is placed in the needle and clamped by the glue barrel clamp. After the steel plate is positioned on station 1 of the steel plate positioning assembly, the servo motor works to control the moving device to use the working principle of converting the rotation of the ball screw into translation, so that the translation device moves horizontally. At the same time, the translation device also translates the cylinder seat through the screw, and uses the optical sensor to position the glue barrel clamp to align with the groove of the steel plate. Then the cylinder works to perform telescopic movement, so that the glue barrel clamp moves down to the gluing distance, and the glue barrel clamped by the glue barrel clamp is glued. The moving device and the translation device make the needle apply glue in a quadrilateral. The side length of the quadrilateral is less than the side length of the baffle. After the gluing is completed, the cylinder shrinks and moves upward to return to its original position.

[0014] Then comes the baffle loading process, the electric control box 7 is powered, and the servo motor works. The vibration table 3-3 vibrates, causing the baffle to vibrate onto the linear feeding channel. When the material in the linear feeding channel moves under the photoelectric switch bracket, the photoelectric switch bracket recognizes the baffle, and the vibration table stops vibrating. The translation device moves, and the moving device drives the cylinder to move horizontally. The suction cup is controlled by the cylinder to suck, and the baffle is lifted and placed on the dipping table for dipping. Then, under the control of the translation device and the moving device, the baffle is placed in the groove of the steel plate that has been coated with glue. At this time, a working cycle of the baffle loading and gluing system 3 is completed.

[0015] The material translation system 1 works, driving the steel plate to move to the station 2. During this process, the electric control box 7 is powered, the servo motor works, and the principle of the ball screw rotation becoming translation is used to make the moving device do translational motion. The translation mechanism 1-1 translates along the y direction, that is, the four cantilever beams translate along the y direction under the action of the translation mechanism, and the rightmost cantilever beam moves to the top of the station 1. At this time, the cylinders of the four cantilever beams do telescopic motion, the electromagnet moves down, and begins to attract, lifting the four steel plates to a certain height. The translation mechanism does a translational motion and moves to the left to the next station. At this time, the cylinders of the four cantilever beams do telescopic motion, the electromagnet moves down, the electromagnet is released, and the steel plate is repositioned at the next station. The steel plate that has just completed the gluing baffle loading process has now been moved and positioned at station 2, which is the welding station.

[0016] The welding process begins, the electric control box 7 supplies power, the servo motor works, and the moving device is controlled to move downward. The welding head 4-1 stops when it reaches the welding distance. At the same time, the bottom heater and the preheating copper block work to heat, and then the tin flows from the bend pipe and drips on the edge of the baffle in the groove of the steel plate. Since the baffle and the steel plate have been coated with solder paste during the pre-treatment process, the fluidity of the tin is greatly increased, and the baffle is automatically positioned on the steel plate and completely sealed. Then the welding head 4-1 works to weld, and after completion, the welding head 4-1 moves up, and the welding is completed.

[0017] After welding is completed, the material translation system 1 works to transport the steel plate to the workstation 3 for heating treatment. After the heating treatment is completed, the steel plate continues to move to the next workstation for unloading under the operation of the material translation system 1. The above steel plate transport and loading system, material translation system, baffle loading and gluing system, and high-temperature welding system are carried out simultaneously with the cooperation of other auxiliary components, and work in coordination to complete the automatic soldering of steel plates and baffles.

[0018] The automatic soldering machine provided by the present invention has an efficient, safe and fast soldering process, which can improve the production efficiency of products, liberate productivity and reduce the manufacturing cost of enterprises. BRIEF DESCRIPTION OF THE DRAWINGS

The material translation system 1 is fixedly installed on the operating table 6, and the steel plate handling and feeding system 2 is installed on one side of the operating table 6. The cantilever beam and other mechanisms of the system and the four cantilever beams and other mechanisms of the material translation system are connected to two sliders and installed on the same guide rail. They all use the principle of ball screw rotation and movement. There is a ball screw under each slider of the two systems, so the movements do not interfere with each other. The baffle feeding and gluing system 3 and the high-temperature welding system 4 are installed on the operating table 6, and the vibration table of the baffle feeding and gluing system is installed on the side of the operating table 6.

[0027] Figure 2 The figure shows a schematic diagram of the material translation system structure, which mainly includes a translation mechanism 1-1, a steel plate 1-2, and a steel plate positioning assembly 1-3. The bottom of the material translation system 1 is a steel plate positioning assembly 1-3 fixed on the operating table 6. The steel plate positioning assembly 1-3 is composed of aluminum profiles, pads, pads and other components. There are five positions where steel plates can be placed during processing. These five steel plate positions are also five workstations. The four cantilever beams in the translation mechanism 1-1 are fixedly connected to the slider of the guide rail. The spacing of the four cantilever beams is the same as the spacing of the five steel plate positions (workstations). There is a ball screw inside the guide rail. During the working process, the ball screw is rotated to drive the slider to move. The servo motor rotates forward and reversely, and the ball screw is driven to rotate forward and reversely through the coupling, which drives the four cantilever beams on the slider to move in the y direction, and then the steel plate moves in the y direction. The middle and tail parts of each cantilever beam are fixedly connected to a cylinder support respectively, and the cylinder support is connected to the cylinder, and the cylinder is connected to the long aluminum profile. There are two electromagnets at the head and tail ends of the aluminum profile. During the process of transporting the steel plate, the electromagnet works to adsorb the steel plate, and the cylinder's telescopic movement drives the steel plate to move up and down.

[0028] Figure 3It is a schematic diagram of the structure of the steel plate handling and feeding system, including a lifting mechanism 2-1, a material cart 2-2, and a steel plate handling mechanism 2-3. The steel plate handling mechanism 2-3 of the steel plate handling and feeding system 2 is fixed on the operating table 6, wherein the cantilever beam mechanism is connected to the guide rail by a slider, and also works on the principle of converting the rotation of the ball screw into the movement of the slider, so that the cantilever beam moves back and forth between the upper part of the material cart and the station 1 on the steel plate positioning assembly on the operating table, and the servo motor rotates forward and reversely, and drives the ball screw to rotate forward and reversely through the coupling, driving the cantilever beam on the slider to move in the y direction, and then the steel plate moves in the horizontal direction. The middle and tail parts of the cantilever beam are connected to two cylinder supports, and the cylinder supports are connected to the cylinder, and the cylinder is connected to the long aluminum profile. Two suction cups are connected to the head and tail ends of the aluminum profile, and the suction cups absorb the steel plate, and under the action of the cylinder, cantilever beam and other mechanisms, the steel plate is transported to the position of the station 1. The trolley 2-2 of the steel plate handling and loading system 2 is fixedly installed on one side of the operating table 6 by the trolley clamping mechanism. The material steel plate is placed on the trolley 2-2, and the lifting mechanism 2-1 is at the bottom of the trolley 2-2. The lifting mechanism 2-1 also uses the working principle of the ball screw rotating and changing movement to realize the action of dragging the material steel plate in the trolley 2-2 up and down. The servo motor rotates forward and reverse, and drives the ball screw to rotate forward and reverse through the coupling, thereby driving the lifting mechanism to move up and down, and then the steel plate on the trolley moves up and down.

[0029] Figure 4 It is a structural diagram of a baffle feeding and gluing system, including a gluing mechanism 3-1, a feeding mechanism 3-2, and a vibration table 3-3. The vibration table 3-3 of the baffle feeding and gluing system 3 is fixedly installed on one side of an operating table 6 by components such as a vibration table bracket. When the vibration table works in vibration mode, the baffle moves to the material channel under the action of vibration, and the feeding mechanism 3-2 is connected to the vibration table 3-3 through the material channel. The feeding mechanism 3-2 and the gluing mechanism 3-1 are installed on the operating table 6. The feeding mechanism 3-2 includes a servo motor, a moving device, a sensor, a cylinder, a suction cup and other components. The gluing mechanism 3-1 includes a servo motor, a moving device, a cylinder, a glue barrel fixture, a glue barrel, glue (solder paste) in the glue barrel and other components. The gluing mechanism 3-1 and the feeding mechanism 3-2 are connected to the slider on the moving device through two cylinder supports. The movement of the moving device is realized by using the working principle of the ball screw rotation to move. The servo motor rotates forward and reverse, and drives the ball screw to rotate forward and reverse through the coupling, driving the gluing mechanism and the feeding mechanism to move forward and backward, and then the glue barrel or the suction cup moves forward and backward. During the working process, the gluing mechanism and the feeding mechanism work without interfering with each other and cooperate with each other.

[0030] Figure 5It is a structural diagram of a high-temperature welding system, including a welding head 4-1, a capillary 4-2, and a moving mechanism 4-3. The welding head 4-1 in the high-temperature welding system 4 is installed on the moving mechanism 4-3. The servo motor rotates forward and reversely, and drives the ball screw to rotate forward and reversely through the coupling, driving the moving mechanism to move up and down, and then the welding head to move up and down. There are two capillary tubes 4-2, which are installed on both sides of the welding head 4-1. The tin flows into the groove of the steel plate to be welded through the capillary tubes. The moving mechanism 4-3 is installed on the operating table 6 through the solder plate.

[0031] In addition to the above-mentioned mechanical components, there is also an automatic control system to coordinate the operating logic of the entire equipment.

[0032] The working process of an automatic soldering machine for bullet packaging boxes is as follows:

[0033] The worker fills the material cart with steel plates, loads enough baffles into the vibration table, fills the plastic bucket with solder paste, prepares the raw tin of the welding system, and starts the machine. Assume that the length direction of the steel plate on the steel plate positioning assembly 1-3 on the operating table 6 is the x direction, and the width direction is the y direction. The steel plate positioning assembly 1-3 has a total of five stations for placing steel plates. The first station for placing steel plates on the side of the material cart 2-2 of the operating table 6 is assumed to be station 1, and stations 2, 3, 4, and 5 along the y direction are respectively.

[0034] First, the steel plate handling and loading system 2 works. During the process of transporting steel plates, the electrical control box 7 supplies power to the lifting mechanism 2-1, and the servo motor in the lifting mechanism 2-1 rotates, which drives the ball screw to rotate through the coupling, thereby driving the lifting mechanism to move upward, thereby lifting the material steel plates in the material cart full of materials (steel plates) until the top layer of steel plates is recognized by the sensor in the limit device. The servo motor stops rotating and the system detects the steel plates. The steel plate handling mechanism 2-3 works, the servo motor in the steel plate handling mechanism 2-3 rotates, drives the ball screw to rotate through the coupling, drives the cantilever beam to move horizontally in the y direction, and the cantilever beam moves to the top of the steel plate on the material cart. Under the cooperation of the cylinder, suction cup and other components, the cylinder extends, the suction cup sucks the steel plate, the cylinder contracts, and the steel plate is lifted from the material cart. The servo motor in the steel plate handling mechanism 2-3 rotates in the opposite direction, drives the ball screw to rotate in the opposite direction through the coupling, drives the cantilever beam to move horizontally in the y direction, and the cantilever beam connected to the slider moves from the top of the steel plate on the material cart to the top of the station 1, the cylinder extends, the suction cup releases the steel plate, and the steel plate is placed in the station 1. Then the baffle feeding and gluing system 3 works to process the steel plate in the next step. After the baffle feeding and gluing system 3 works for one cycle, the material translation system 1 works. At this time, the steel plate that has completed the gluing and baffle feeding processes on the station 1 is transported to the station 2 under the action of the material translation system 1. At this time, the steel plate handling and feeding system 2 works again, and carries the second steel plate to the work station 1, and repeats the above working process. After carrying the steel plates five times, the lifting mechanism 2-1 of the steel plate handling and feeding system 2 works, and drags the steel plates on the material cart 2-2 up by 5mm (the height of five steel plate thicknesses). When the top steel plate is recognized by the sensor on the limit device, the above working process is repeated. During the lifting process, when the lifting mechanism 2-1 drags the steel plate up by 5mm, the sensor in the limit device does not recognize the steel plate, and the system recognizes it as a lack of material state. At this time, the system alarms to remind the worker to add material. At this time, the worker opens the door of the material cart and fills it with steel plates.

[0035] Next is the process of gluing the baffle. During the gluing process, the solder paste is placed in a syringe and clamped by a syringe clamp. After the steel plate is positioned on station 1 of the steel plate positioning assembly, the servo motor rotates, drives the ball screw to rotate through the coupling, drives the slider to move in the x direction, and then the cylinder seat connected to the slider, the cylinder connected to the cylinder seat, and the glue barrel clamp connected to the cylinder move the glue barrel in the x direction. The optical sensor is used to position the glue barrel clamp to align with the groove of the steel plate, and then the cylinder works to extend, so that the glue barrel clamp moves down to the gluing distance, and the glue barrel clamped by the glue barrel clamp is glued. The moving device and the translation device drive the glue barrel to make the glue barrel apply glue in a quadrilateral on the groove of the steel plate. The side length of the quadrilateral is less than the side length of the baffle. After the gluing is completed, the cylinder shrinks, and the glue barrel moves up and returns to its original position.

[0036] Then comes the baffle loading process. The electric control box 7 is powered, the servo motor rotates, and the ball screw is driven to rotate through the coupling, driving the slider to move in the x direction, and then the cylinder seat connected to the slider, the cylinder connected to the cylinder seat, and the suction cup connected to the cylinder move in the x direction, and are positioned by the sensor to move to the material taking position of the material channel. At the same time, the vibration table 3-3 vibrates, so that the baffle vibrates to the linear feeding channel. When the material in the linear feeding channel moves under the photoelectric switch bracket, the photoelectric switch bracket recognizes the baffle, and the vibration table stops vibrating. The cylinder extends, the suction cup absorbs the baffle, the cylinder contracts, the servo motor reverses, the ball screw reverses, and then the absorbed baffle moves in the opposite direction, moves to the dipping table for dipping, and then continues to move to the top of the groove of the steel plate on the station 1. The cylinder extends, the suction cup is released, and the baffle is placed in the groove of the steel plate that has been glued. At this time, a working cycle of the baffle loading and gluing system 3 is completed.

[0037] The material translation system 1 works, driving the steel plate to move to the workstation 2. During this process, the electric control box 7 is powered, the servo motor rotates, and the ball screw is driven to rotate through the coupling, driving the cantilever beam of the mechanism 1-1 to move in the y direction, that is, the four cantilever beams move in the y direction under the action of the translation mechanism, and the rightmost cantilever beam moves to the top of the workstation 1. At this time, the cylinders of the four cantilever beams extend, the electromagnet moves down, and the steel plate is attracted. The cylinder contracts and the four steel plates are lifted to a certain height. The servo motor rotates, and the ball screw is driven to rotate through the coupling, driving the cantilever beam of the translation mechanism 1-1 to move in the y direction, that is, the four cantilever beams move in the y direction under the action of the translation mechanism, and then the steel plate attracted by the electromagnet moves in the y direction, and each steel plate moves to the next workstation, that is, the steel plate at workstation 1 moves to workstation 2. At this time, the cylinders of the four cantilever beams work, the electromagnet moves down, the electromagnet is released, and the steel plate is repositioned at the next workstation. The steel plate that has just completed the glue-coated baffle loading process has now been moved and positioned on station 2, which is the welding station.

[0038] When the welding process starts, the electric control box 7 is powered, the servo motor rotates, and the ball screw is driven to rotate through the coupling, which drives the moving mechanism 4-3 to move up and down, and then drives the welding head 4-1 to move up and down. The welding head 4-1 stops when it reaches the welding distance. At the same time, the bottom heater and the preheating copper block work to heat, and then the tin flows from the bend pipe and drips on the edge of the baffle in the groove of the steel plate. Since the baffle and the steel plate have been coated with solder paste during the pre-treatment process, the fluidity of the tin is greatly increased, and the baffle is automatically positioned on the steel plate and completely sealed. Then the welding head 4-1 works to weld, and after completion, the welding head 4-1 moves up, and the welding is completed.

[0039] After welding is completed, the material translation system 1 works to transport the steel plate to the workstation 3 for heating treatment. After the heating treatment is completed, the steel plate continues to move to the next workstation for unloading under the operation of the material translation system 1. The above steel plate transport and loading system, material translation system, baffle loading and gluing system, and high-temperature welding system are carried out simultaneously with the cooperation of other auxiliary components, and work in coordination to complete the automatic soldering of steel plates and baffles.

[0040] The above-described embodiments merely express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.

2. A method for operating the automatic sealing machine for galvanized iron box of bullets as claimed in claim 1, It is characterized by the following steps: In the first step, the length direction of the steel plate (1-2) on the steel plate positioning assembly (1-3) on the operating table (6) is the x direction, and the width direction is the y direction. The steel plate positioning assembly (1-3) has a total of five workstations for placing the steel plate (1-2). The first workstation for placing the steel plate (1-2) on the side of the operating table (6) with the material cart (2-2) is assumed to be workstation 1, and along the y direction are workstations 2, 3, 4, and 5 respectively; Step 2: Steel plate handling and loading system (2) works In the process of transporting the steel plates (1-2), the transporting and loading system is powered by the electric control box (7), the servo motor is operated, the material lifting mechanism (2-1) is operated, and the material cart full of steel plates (1-2) lifts the material steel plates (1-2) under the action of the material lifting mechanism (2-1). When the uppermost steel plates (1-2) rise to the point where they are recognized by the sensor in the limit device, the system detects the steel plates (1-2), the steel plate transporting mechanism (2-3) is operated, the cantilever beam moves, the suction cup sucks the steel plates (1-2) and lifts the steel plates (1-2) from the material cart, and the slider moves so that the steel plates sucked by the suction cups on the cantilever beam are sent to the workstation 1; Step 3: The baffle feeding and gluing system (3) works The steel plate is processed in the next step; after the baffle loading and gluing system (3) works for one cycle, the material translation system (1) works, and at this time, the steel plate (1-2) that has completed the gluing and baffle loading processes at station 1 is transported to station 2 under the action of the material translation system (1); at this time, the steel plate transporting and loading system (2) works again to transport the second steel plate to station 1, and repeats the above working process. After transporting five steel plates, the lifting mechanism (2-1) of the steel plate transporting and loading system (2) works to drag the steel plate on the material car (2-2) to a height of five steel plate thicknesses. When the uppermost steel plate is recognized by the sensor on the limit device, the above working process is repeated; during the lifting process, when the lifting mechanism (2-1) drags the steel plate to a height of five steel plate thicknesses, the sensor in the limit device does not recognize the steel plate, and the system recognizes it as a material shortage state. At this time, the system alarms to remind you to replenish the material; The fourth step is to load and glue the baffle During the glue coating process, the solder paste is placed in a syringe and clamped by a glue barrel fixture; After the steel plate is positioned on the station 1 of the steel plate positioning assembly, the servo motor works to control the movement to make the translation device move horizontally. At the same time, the translation device works through the lead screw to make the cylinder seat move horizontally. The optical sensor is used to position the glue barrel fixture to align with the groove of the steel plate. The cylinder works to make a telescopic movement to move the glue barrel fixture down to the glue coating distance. The glue barrel clamped by the glue barrel fixture is glued. The moving device and the translation device make the needle tube glue in a quadrilateral. The side length of the quadrilateral is less than the side length of the baffle. After the glue coating is completed, the cylinder shrinks and moves upward to return to its original position. Step 5: Load the baffle The electric control box (7) supplies power and the servo motor starts working; the vibration table (3-3) vibrates, causing the baffle to vibrate onto the linear feeding path. When the material in the linear feeding path moves under the photoelectric switch bracket, the photoelectric switch bracket recognizes the baffle, and the vibration table stops vibrating; the translation device moves, and the moving device drives the cylinder to move horizontally. The suction cup is controlled by the cylinder to suck, and the baffle is lifted and placed on the dipping table for dipping. Under the control of the translation device and the moving device, the baffle is placed in the groove of the steel plate that has been coated with glue. At this time, a working cycle of the baffle feeding and gluing system (3) is completed; In the sixth step, the material translation system (1) drives the steel plate to move to the workstation 2. During this process, the electric control box (7) is powered, the servo motor works, and the moving device performs translational motion. The translation mechanism (1-1) translates along the y direction. The four cantilever beams translate along the y direction under the action of the translation mechanism. The rightmost cantilever beam moves to the top of the workstation 1. At this time, the cylinders of the four cantilever beams perform telescopic motion, the electromagnets move downward, and begin to attract, lifting the four steel plates to a certain height. The translation mechanism performs translational motion and moves to the left to the next workstation. At this time, the cylinders of the four cantilever beams perform telescopic motion, the electromagnets move downward, the electromagnets are released, and the steel plates are repositioned at the next workstation. The steel plate that has just completed the gluing baffle loading process has now been moved and positioned at workstation 2, that is, the welding workstation. Step 7: Start the welding process The electric control box (7) supplies power, the servo motor starts to work, and the moving device is controlled to move downward. The welding head (4-1) stops when it reaches the welding distance. At the same time, the bottom heater and the preheating copper block start to heat. Tin flows in from the bent pipe and drips onto the edge of the baffle in the groove of the steel plate, thereby achieving automatic positioning and complete sealing of the baffle on the steel plate. The welding head (4-1) starts to weld, and after completion, the welding head (4-1) moves upward, and the welding is completed. In the eighth step, after welding is completed, the material translation system (1) works to transport the steel plate to the work station 3 for heating treatment. After the heating treatment is completed, the steel plate continues to move to the next work station for unloading under the operation of the material translation system (1); the above steel plate transport and loading system (2), material translation system, baffle loading and gluing system, and high-temperature welding system, with the cooperation of other auxiliary components, work simultaneously and coordinately to complete the automatic soldering and sealing work of the steel plate and the baffle.
