Especially in the fields of chip packaging, micro-electromechanical systems in aerospace, automobiles and high-speed rails, the pitch of welding points is continuously reduced, and the precision and reliability of welding materials are almost strictly required. Environment-friendly lead-free solder has become the mainstream choice for electronic component welding, but its production technology has encountered many difficult problems, especially the serious deficiencies of traditional continuous casting equipment in forming precision and production efficiency, which has become a major obstacle to the development of the industry.

[0003] At present, horizontal continuous casting technology is widely used due to its high efficiency, but the traditional equipment adopts chain or belt transmission for the circulating conveying of the mold body, which is easy to cause unstable operation due to uneven stress, and the equipment is easy to wear out under high temperature environment, affecting the continuous operation efficiency of the equipment. Moreover, the temperature control of the tin material solidification process is mostly single cooling mode, which cannot realize gradient cooling along the continuous casting direction, and is easy to produce shrinkage cavity, crack and other defects due to uneven cooling rate, resulting in the decrease of mechanical properties of tin bar. In addition, the mold body transfer, tin material casting and demolding of the existing equipment have poor coordination and low automation, which not only increases the labor cost, but also is difficult to ensure the production consistency.

[0030] The embodiment of the present application discloses a tin bar horizontal continuous casting equipment based on gradient temperature control.

[0032] In the working process, the driving assembly 200 drives the plurality of mold bodies 104 to seal sliding in the horizontal continuous casting slide 102 and the horizontal recycling slide 103 below, the mold body input assembly 300 transfers the mold bodies 104 in the horizontal recycling slide 103 to the horizontal continuous casting slide 102 one by one, and the mold body output assembly 400 transfers the mold bodies 104 in the horizontal continuous casting slide 102 to the horizontal recycling slide 103 one by one, so that the mold bodies 104 are circulated and slid in the horizontal continuous casting slide 102 and the horizontal recycling slide 103.

[0033] When the mold body 104 moves to the melting assembly 500 along the track, the melting assembly 500 heats the tin material to a liquid state and injects it into the cavity 105 of the mold body 104, and then the mold body 104 moves along the length direction of the mold body 101 with the liquid tin material, at this time, the gradient temperature control assembly 800 controls the temperature of the tin material in the cavity 105 along the length direction of the mold body 101 to make the tin material gradually solidify into a tin strip according to the set temperature gradient.

[0034] When the tin strip moves to the demolding assembly 600 along with the mold body 104, the demolding assembly 600 performs demolding operation on the tin strip, the discharged assembly 700 collects and transports the demolded tin strip out, and the empty mold body 104 returns to the mold body input assembly 300 through the horizontal recycling slide 103, so as to realize continuous casting of the tin strip through the circulation.

[0035] Please refer to Figures 1 to 8 In one specific embodiment of the present application, the driving assembly 200 includes a first driving screw 201 and a second driving screw 202, the top surface of the horizontal continuous casting slide 102 is provided with a first installation cavity 203 penetrating the horizontal continuous casting slide 102 near the positions of the two side surfaces, the bottom surface of the horizontal recycling slide 103 is provided with a second installation cavity 204 penetrating the horizontal recycling slide 103 near the positions of the two side surfaces, the first installation cavity 203 is rotationally connected with the first driving screw 201 inside, the second installation cavity 204 is rotationally connected with the second driving screw 202 inside, the top surface of the mold body 104 is provided with a first driving helical groove 205 near the positions of the two side surfaces corresponding to the first driving screw 201, the bottom surface of the mold body 104 is provided with a second driving helical groove 206 near the positions of the two side surfaces corresponding to the second driving screw 202, and the first driving screw 201 and the second driving screw 202 are transmissionally connected with a driving piece 207 penetrating the outer end of the mold body 101.

[0036] In the working process, the driving member 207 synchronously drives the first driving screw 201 and the second driving screw 202 to rotate. When the first driving screw 201 rotates, the first driving screw groove 205 will be engaged with the thread of the first driving screw 201 to convert the rotary motion into the linear motion of the mold body 104. The mold body 104 in the horizontal continuous casting slide 102 is driven by the first driving screw 201 to move forward, moving the mold body 104 from the mold body input assembly 300 to the mold body output assembly 400; the mold body 104 in the horizontal recycling slide 103 is driven by the second driving screw 202 to move reversely, moving the mold body 104 from the mold body output assembly 400 to the mold body input assembly 300, forming a closed loop circulation.

[0037] Please refer to Figures 1 to 8 In an embodiment of the present application, the driving member 207 is configured as a stepper motor, which is driven by a pulse signal to realize open-loop precise position control, and does not need a feedback system to meet most precise control requirements. At the same time, the stepper motor has a significant low-speed high-torque characteristic, and can stably and reliably drive the first driving screw 201 and the second driving screw 202 to rotate, which is conducive to simplifying the mechanical structure. In addition, the stepper motor has a simple and reliable structure, no brush commutator, and strong anti-interference, which is conducive to improving the environmental adaptability.

[0038] Please refer to Figures 1 to 8 In an embodiment of the present application, the driving member 207 is fixedly installed on the front end cover 106, the output shaft of the driving member 207 penetrates one end of the front end cover 106, and the first driving gear 208 is fixedly installed inside the front end cover 106. The front end cover 106 is rotatably connected with two symmetrically arranged intermediate driven gears 209 corresponding to the first driving gear 208, the intermediate driven gears 209 are in meshing transmission with the first driving gear 208, the first driven gears 210 are installed in the front end cover 106 corresponding to the first driving screw 201 and the second driving screw 202, the first driven gears 210 are in meshing transmission with the intermediate driven gears 209, and the first driven gears 210 are installed on the first driving screw 201 and the second driving screw 202.

[0039] In the working process, after the driving member 207 is powered on, the output shaft drives the first driving gear 208 to rotate. The first driving gear 208 drives the two symmetrically arranged intermediate driven gears 209 to reversely rotate at the same time, forming a double-output transmission path. The intermediate driven gears 209 are in meshing transmission with the first driven gears 210 installed on the first driving screw 201 and the second driving screw 202, synchronously transmitting power to the first driving screw 201 and the second driving screw 202, and the first driving screw 201 and the second driving screw 202 synchronously rotate in the same direction, thereby synchronously driving the mold body 104 in the horizontal continuous casting slide 102 and the horizontal recycling slide 103 to move synchronously.

[0040] Please refer to Figures 1 to 8 In one embodiment of the present application, the helix of the first drive screw 201 and the second drive screw 202 is opposite, so that the mold body 104 in the horizontal continuous casting slide 102 and the horizontal recycling slide 103 can realize synchronous reverse movement.

[0041] Please refer to Figures 1 to 8 In one embodiment of the present application, the mold body input assembly 300 includes a first telescopic piece 301, which is fixedly installed at one end of the bottom surface of the mold main body 101 close to the melting assembly 500. The telescopic end of the first telescopic piece 301 extends through the mold main body 101 to the inside of the horizontal recycling slide 103. The inside of the mold main body 101 is provided with an input channel 302 communicating with the horizontal continuous casting slide 102 and the horizontal recycling slide 103. The telescopic end of the first telescopic piece 301 is fixedly installed with a first supporting plate 303, and the first supporting plate 303 is fixedly installed with a first magnetic plate 304.

[0042] In the working process, the first telescopic piece 301 is first in the retracted state, and the first supporting plate 303 and the first magnetic plate 304 are located in the horizontal recycling slide 103, waiting for the arrival of the empty mold body 104. When the empty mold body 104 moves to above the first supporting plate 303 through the horizontal recycling slide 103, the driving assembly 200 is paused, and the mold body 104 is accurately positioned below the input channel 302. The magnetic force generated by the first magnetic plate 304 will be adsorbed to the bottom surface of the mold body 104, and after the first magnetic plate 304 and the mold body 104 are adsorbed stably, the first telescopic piece 301 is extended, driving the first supporting plate 303 and the mold body 104 to vertically ascend along the input channel 302. When the mold body 104 rises to the height of the horizontal continuous casting slide 102, the first drive helical groove 205 at the top thereof is accurately meshed with the first drive screw 201, and the front end is connected with the front mold body 104. The driving assembly 200 is started, driving the newly added mold body 104 to move along with the horizontal continuous casting slide 102 to below the melting assembly 500, starting a new round of casting, and at the same time, the first telescopic piece 301 is retracted and reset, waiting for the continuous input of the mold body 104. The design realizes the transfer of the mold body between the two horizontal slides through vertical linear motion, which is beneficial to reducing space occupation and avoiding the risk of inclination of the mold body 104 compared with the traditional horizontal pushing or rotating switching mode.

[0043] In one embodiment of the present application, in order to ensure the reliable adsorption between the first magnetic plate 304 and the mold body 104, the first magnetic plate 304 is made of permanent magnetic material, and the corresponding magnetic material is installed on the mold body 104, ensuring the firm connection between the first magnetic plate 304 and the mold body 104.

[0044] Please refer to Figures 1 to 8 In one specific embodiment of the present application, the mold output assembly 400 comprises a second telescopic piece 401, which is fixedly installed at the end of the mold main body 101 away from the melting assembly 500, and the telescopic end of the second telescopic piece 401 extends through the mold main body 101 to the inside of the horizontal recycling slide 103. The inside of the mold main body 101 is provided with an output channel 402 corresponding to the mold body 104, which communicates with the horizontal continuous casting slide 102 and the horizontal recycling slide 103. The telescopic end of the second telescopic piece 401 is fixedly installed with a second supporting plate 403 corresponding to the output channel 402, and the second supporting plate 403 is fixedly installed with a second magnetic plate 404.

[0045] In the working process, the second telescopic piece 401 is first in the extended state, and the second supporting plate 403 and the second magnetic plate 404 are located in the output channel 402. When the empty mold body 104 after casting and demolding moves to above the output channel 402 along the horizontal continuous casting slide 102, the driving assembly 200 is paused, and the mold body 104 is accurately positioned directly above the output channel 402. At this time, the magnetic force generated by the second magnetic plate 404 will firmly attract the mold body 104. The second telescopic piece 401 is retracted, driving the mold body 104 to vertically descend along the output channel 402 to the height of the horizontal recycling slide 103. During the descent of the mold body 104, the first driving helical groove 205 at the top thereof is separated from the first driving screw 201, and the second driving helical groove 206 at the bottom thereof is engaged with the second driving screw 202. The driving assembly 200 is started again, driving the mold body 104 to return to the mold input assembly 300 along the horizontal recycling slide 103, completing the cycle. At the same time, the second telescopic piece 401 is extended again, driving the second supporting plate 403 to rise into the output channel 402, waiting for the output of the mold body 104.

[0046] In one specific embodiment of the present application, in order to ensure the reliable adsorption between the second magnetic plate 404 and the mold body 104, the second magnetic plate 404 is also made of permanent magnetic material, and the second magnetic plate 404 can reliably adsorb the magnetic material installed on the second magnetic plate 404 of the mold body 104, ensuring the firm connection between the second magnetic plate 404 and the mold body 104.

[0047] Please refer to Figures 1 to 8In an embodiment of the present application, the first telescopic member 301 and the second telescopic member 401 are both electric telescopic rods, which can accurately control the telescopic amount, ensure the accurate positioning of the mold body 104 when vertically transferred between the horizontal continuous casting slide 102 and the horizontal recycling slide 103, and ensure the accurate meshing of the spiral groove and the driving screw and the butt joint of the mold body.

[0049] In the working process, the lead-free solder raw material can be put into the smelting kettle 501 through the feeding hopper 518, and the lead-free solder in the smelting kettle 501 is heated to a molten state through the electromagnetic induction heating coil 502. Then the driving shaft 505 is driven to rotate forward by the second driving assembly, and when the driving shaft 505 rotates forward, the limiting pin 508 enters the annular groove 507 located at the upper end of the limiting groove 506 due to the cooperation of the limiting pin 508 and the spiral limiting groove 506, so that the driving shaft 505 moves downward to the limit position, so that the valve ball 509 at the bottom of the driving shaft 505 blocks the discharge port 511. At the same time, the stirring frame 520 on the driving shaft 505 stirs the molten material to ensure uniform composition.

[0051] In the working process, the second driving assembly realizes the combined action of rotation and axial movement of the main shaft 505 through spline transmission. The second motor 517 drives the second driving gear 519 to rotate, which drives the second driven gear 516 and the transmission sleeve 513 fixed thereto to rotate. The spline groove 514 in the transmission sleeve 513 cooperates with the spline teeth 515 on the main shaft 505, so that the rotary motion of the transmission sleeve 513 is transmitted to the main shaft 505. At the same time, the helical limiting groove 506 on the main shaft 505 interacts with the limiting pin 508 on the limiting sleeve 504, converting the rotary motion of the main shaft 505 into axial reciprocating motion. This combined motion enables the valve ball 509 at the bottom of the main shaft 505 to both rotate and stir the molten material, and reliably open and close the discharge port 511, realizing the quantitative delivery and uniform stirring of the molten solder.

When the mold body 104 moves to the corresponding position of the discharge assembly 700, the driving assembly 200 is paused, and at the same time, the jacking assembly in the mold main body 101 generates an upward thrust to push the magnetic block 604 to move upward against the elastic force of the reset spring 606.

After demolding is completed, the jacking assembly resets, the reset spring 606 pushes the magnetic block 604 and the push block 601 to fall back to the initial position, the mold cavity 105 returns to the original state, and is ready for the next casting. The driving assembly 200 is started again, and the mold body 104 continues to move away from the jacking assembly.

[0055] In the working process, the jacking assembly realizes stable jacking action through screw drive and multi-rod linkage. When the third motor 620 drives the screw drive shaft 607 to rotate in the sliding groove 612, the first screw drive groove 6071, the second screw drive groove 6072, the third screw drive groove 6073, and the fourth screw drive groove 6074 on the shaft respectively drive the corresponding first sliding block 608, the second sliding block 609, the third sliding block 610, and the fourth sliding block 611 to slide along the sliding groove 612.

[0056] Since the first helical driving groove 6071 is symmetrically arranged with the second helical driving groove 6072, the second helical driving groove 6072 is symmetrically arranged with the third helical driving groove 6073, and the third helical driving groove 6073 is symmetrically arranged with the fourth helical driving groove 6074, when the helical driving shaft 607 rotates forward, the first slider 608 and the second slider 609 move close to each other, the third slider 610 and the fourth slider 611 move close to each other, and the first inclined strut 616 and the second inclined strut 617 and the third inclined strut 618 and the fourth inclined strut 619 are respectively folded around the hinge points, and the first hinge seat 614 and the second hinge seat 615 lift the lifting pallet 613; when the helical driving shaft 607 rotates reversely, the first slider 608 and the second slider 609 move away from each other, the third slider 610 and the fourth slider 611 move away from each other, and the first inclined strut 616 and the second inclined strut 617 and the third inclined strut 618 and the fourth inclined strut 619 are respectively unfolded around the hinge points, and the first hinge seat 614 and the second hinge seat 615 drive the lifting pallet 613 to descend and reset. The whole process realizes the stable lifting of the lifting pallet 613 through the linkage of the symmetrically arranged sliders and the inclined struts.

[0057] Please refer to Figures 1 to 8 In an embodiment of the present application, the discharge assembly 700 comprises a discharge groove 701, which is arranged at the top surface of the mold body 101 corresponding to the demolding assembly 600, and two installation grooves 702 are arranged on the opposite sides of the discharge groove 701. The two installation grooves 702 are symmetrically and slidingly connected with damping blocks 703 inside, and damping springs 704 are fixedly installed inside the installation grooves 702 and abut on the damping blocks 703. A smooth transition inclined surface 705 is arranged on the damping block 703 corresponding to the opening of the cavity 105.

[0058] In the working process, the discharge assembly 700 realizes the stable discharge of the casting through damping buffering and inclined surface guiding. When the demolding assembly 600 lifts the casting to the position of the discharge groove 701, the two sides of the casting first contact the inclined surface 705 of the damping block 703. The smooth transition inclined surface 705 guides the casting to slide along the inclined surface into the discharge groove 701, and the damping block 703 slides into the installation groove 702 under the pushing force of the casting, compressing the damping spring 704.

[0059] The elastic force of the damping spring 704 provides a reverse resistance to slow down the sliding speed of the casting, avoiding the collision of the casting with the edge of the discharge groove 701 or the bouncing due to the excessive demolding impact force. The whole process realizes the smooth transition of the casting from the cavity 105 to the discharge groove 701 through the guidance of the inclined surface 705 and the buffering of the damping spring 704.

[0060] Please refer to Figures 1 to 8In an embodiment of the present application, the gradient temperature control assembly 800 comprises a refrigerator 801, which has a cooling medium inside, and a cooling medium input main pipe 802 and a delivery pump 803 fixedly connected to the refrigerator 801, and a cooling medium output main pipe 804 fixedly installed on the delivery pump 803. The mold body 104 is provided with symmetrically arranged cooling cavities 805 corresponding to the cavities 105 inside the mold body 104, and the two ends of the mold body 104 are sealingly and slidably connected to the two side surfaces of the horizontal continuous casting slide 102 and the horizontal recovery slide 103. The two ends of the cooling cavities 805 penetrate the two ends of the mold body 104, and the mold body 101 is provided with a plurality of cooling medium delivery ports 806 penetrating the horizontal continuous casting slide 102 corresponding to the two ends of the cooling cavities 805, and the cooling medium delivery ports 806 are connected between the cooling medium input main pipe 802 and the cooling medium output main pipe 804.

[0061] In the working process, the gradient temperature control assembly 800 realizes accurate control of the mold temperature through a closed-loop cooling system. After the cooling medium is cooled by the refrigerator 801, it is delivered to the gradient temperature control pipeline system through the cooling medium input main pipe 802 by the delivery pump 803. The pipeline system distributes the cooling medium to the cooling cavities 805 at the corresponding positions through the cooling medium delivery ports 806 according to the position of the mold body 104.

[0062] When the mold body 104 slides in the horizontal continuous casting slide 102, the cooling medium delivery ports 806 will intermittently sealingly communicate with the cooling cavities 805. The cooling medium flows intermittently in the cooling cavities 805, absorbs the heat around the cavities 105, thereby reducing the temperature of the mold body 104. The cooled cooling medium will flow into the gradient temperature control pipeline system through the cooling medium delivery ports 806 on the other side, and then be delivered to the cooling medium output main pipe 804 by the gradient temperature control pipeline system, and then be returned to the refrigerator 801 for recooling, forming a closed-loop circulation.

[0063] Please refer to Figures 1 to 8 In an embodiment of the present application, the gradient temperature control pipeline system comprises a plurality of branch input pipes 807 sealingly connected in parallel to the cooling medium output main pipe 804, the ends of the branch input pipes 807 away from the cooling medium output main pipe 804 are sealingly connected in parallel to at least three cooling medium delivery ports 806 located on the same side of the mold body 101, and a flow control valve 808 is installed between the branch input pipes 807 and the cooling medium output main pipe 804; a plurality of branch output pipes 809 are sealingly connected in parallel to the cooling medium input main pipe 802 corresponding to the branch input pipes 807, and the ends of the branch output pipes 809 away from the cooling medium input main pipe 802 are sealingly connected corresponding to the cooling medium delivery ports 806 located on the side of the mold body 101 away from the branch input pipes 807; and a temperature sensor 810 is installed on the mold body 101 corresponding to each group of branch input pipes 807 and branch output pipes 809.

[0064] In the working process, the gradient temperature control pipeline system realizes the gradient adjustment of the mold temperature through group control and closed-loop feedback. The cooling medium provided by the refrigerator 801 is distributed to each branch input pipe 807 through the cooling medium input main pipe 802, and the cooling medium is sent into the cooling cavity 805 of the mold body 104 through the corresponding position of the plurality of cooling medium conveying ports 806. The cooling medium after absorbing heat flows into the branch output pipe 809 from the cooling medium conveying port 806 on the other side, and finally flows back to the refrigerator 801 through the cooling medium output main pipe 804, forming a cycle.

[0065] The temperature sensor 810 monitors the temperature of the mold area corresponding to each group of branch input pipes 807 and branch output pipes 809 in real time, and transmits the data to the controller. When the monitored temperature deviates from the preset gradient, the controller adjusts the flow control valve 808 on the branch input pipe 807 to change the flow of the cooling medium: when the temperature is too high, the flow is increased to enhance the cooling effect; when the temperature is too low, the flow is reduced to reduce the cooling intensity. Through the independent control of multiple groups of branch pipes, the temperature gradient of different areas of the mold is accurately controlled.

[0066] The implementation principle of the tin bar horizontal continuous casting equipment based on gradient temperature control according to the embodiment of the application is as follows: The rack 100 is taken as the support basis, the horizontal continuous casting slide 102 and the horizontal recovery slide 103 inside the mold main body 101 form a closed-loop track, and a plurality of mold bodies 104 connected end to end move along the track under the driving of the driving assembly 200. In the driving assembly 200, the first driving screw 201 and the second driving screw 202 rotate synchronously under the action of the driving piece 207 and the gear transmission structure, and drive the mold bodies 104 in the horizontal continuous casting slide 102 and the horizontal recovery slide 103 to move reversely respectively through the meshing with the spiral grooves on the mold bodies 104, so that the stable closed-loop circulation is realized.

[0067] The mold body input assembly 300 and the mold body output assembly 400 drive the magnetic suction plates through the electric telescopic rods, respectively complete the lifting and transfer of the mold bodies 104 from the horizontal recovery slide 103 to the horizontal continuous casting slide 102 and the reverse downward transfer, ensure the seamless connection of the mold bodies 104 between the two slides, and ensure the precise meshing of the spiral grooves and the screws through the permanent magnetic adsorption and precise positioning.

[0068] When the mold body 104 moves to the melting assembly 500, the electromagnetic induction heating coil 502 in the melting kettle 501 melts the tin material into a liquid state, the second driving assembly drives the driving shaft 505 to rotate, the lifting of the valve ball 509 is realized through the cooperation of the spiral limiting groove and the limiting pin, the molten tin material is injected into the cavity 105 through the flow guide seat 510, and the stirring frame 520 stirs the molten material to ensure uniform composition.

[0069] When the mold body 104 moves along the horizontal continuous casting slide 102 with the liquid tin material, the gradient temperature control assembly 800 starts to work: the cooling medium provided by the refrigerator 801 is intermittently introduced into the cooling cavity 805 of the mold body 104 through the gradient temperature control pipeline system and the cooling medium delivery port 806, the temperature sensor 810 monitors the temperature of each region in real time, and the controller changes the flow of the cooling medium in different regions by adjusting the flow control valve 808, so as to form a temperature gradient along the continuous casting direction, and make the tin material gradually solidify and form at a set rate.

[0070] When the solidified tin bar moves to the demolding assembly 600 along with the mold body 104, the third motor 620 drives the screw drive shaft 607 to rotate, drives the lifting support plate 613 to rise through the linkage of the sliding block and the inclined support rod, pushes the magnetic block 604 to overcome the elastic force of the return spring 606, and makes the push block 601 push out the tin bar; the demolded tin bar enters the discharging assembly 700, is stably dropped into the discharging chute 701 and is discharged out through the slope guidance of the damping block 703 and the buffering action of the damping spring 704.

[0071] The empty mold body 104 is transferred to the horizontal recycling slide 103 through the mold body output assembly 400, returns to the mold body input assembly 300 along the track, and enters the next cycle. The whole process realizes the continuous and automatic production of the tin bar through the cooperation of each assembly, guarantees the quality of the tin bar through the gradient temperature control, improves the production efficiency through the closed loop circulation, and reduces the energy consumption and maintenance cost at the same time.

[0072] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
