Description

Technical Field

[0001] The present invention relates to the technical field of feeding equipment, and specifically to an automatic feeding equipment for a fixing machine. Background Art

[0002] In the production process of solar panels, gluing is a crucial step. The main purpose of gluing is to firmly bond components such as solar cells, backsheets, and glass together to form a stable and efficient solar panel structure. During the gluing process, if there are bubbles in the glue, it will cause serious harm and impact on the gluing quality. Bubbles will occupy the contact area between the glue and the substrate, resulting in a reduction in the bonding area, thereby reducing the bonding strength. After curing, the bubbles will form protrusions or depressions on the surface of the solar panel, affecting the appearance quality of the product. Moreover, the presence of bubbles may reduce the weather resistance, water resistance, and other properties of the solar panel, shortening the service life of the product.

[0003] In the existing gluing equipment for eliminating bubbles in the glue, ultrasonic equipment is usually simply used. However, when facing glue with a large volume and high viscosity, the effect of discharging bubbles by ultrasonic equipment is limited. This is because the propagation and attenuation of the vibration energy of ultrasonic waves in the glue are affected by the volume and viscosity of the glue, resulting in bubbles being difficult to be effectively discharged.

[0004] In view of this, the present application is specifically proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic feeding equipment for a fixing machine to solve the problems raised in the above background art.

[0008] Furthermore, a plurality of telescopic rods distributed in an annular array along the axial direction of the fixed block are fixed on the outer arc wall of the fixed block.

The fixing plate is fixed on the top of the outer ring and the end of the telescopic rod far away from the fixed block. A motor is fixed on the top of the limiting disk. The output end of the motor penetrates through the limiting disk and is fixed on the top of the fixed block.

[0009] Furthermore, at positions corresponding to the four driven gears on the top of the fixed disk, inclined sliding grooves are formed, which penetrate the fixed disk in the vertical direction. A stirring shaft is fixed to the bottom of the driven gear, and the end of the stirring shaft away from the driven gear penetrates the inclined sliding groove and is arranged in the liquid storage cavity. The inner ring of the three-ring bearing is fixed with a fixed shaft, and the stirring shaft is sleeved outside the fixed shaft. The top of the fixed shaft and the top of the telescopic rod are fixed through a switching part.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the cooperation of the driving mechanism and the guidance and restriction of several sliding grooves on the limiting disk, several stirring mechanisms can be driven to stir the axial central area and the outer edge area of the colloid in the first box body. While ensuring the mixing of the glue itself and maintaining the fluidity of the glue to avoid stratification and precipitation, the targeted stirring method can promote the bubbles in the area where bubbles are relatively easy to gather to rise or aggregate with each other along with the stirring, which is convenient for their rupture and discharge. And when the stirring mechanism switches the stirring area in the radial direction, it can also assist in scraping the bubbles on the surface of the colloid.

[0013] 2. Through the vibration mechanism inside the fixed cylinder, the driving force of the driving mechanism drives the stirring blades to vibrate, which can accelerate the rupture of air bubbles. This vibration effect can generate a certain degree of vortex and shear force in the glue, contributing to the rupture and discharge of air bubbles buried deep inside the glue, and further enhancing the uniformity of stirring.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to the attached Figure 10 , the present invention provides an automatic feeding device for a fixing machine: including a conveyor belt 10, a glue application robot assembly 11 and a glue application head 12. A telescopic hose 13 is fixed on the top of the glue application head 12, and one end of the telescopic hose 13 far from the glue application head 12 is connected to the center of the bottom of the box body 14; Among them, the glue application robot assembly 11 is an existing known technology and will not be elaborated here. The conveyor belt 10 is arranged below the glue application robot assembly 11 for transporting solar panels so that the glue application robot assembly 11 drives the glue application head 12 to perform glue application operations. The telescopic hose 13 is used to transport glue to the glue application head 12. A glue pump is arranged in the box body 14, and the glue pump is used to transport the glue in the liquid storage cavity of the box body 14 to the glue application head 12 through the telescopic hose 13 and spray it out. An electric component for controlling the opening and closing of the glue application head 12 is arranged on the glue application robot assembly 11 and will not be elaborated here.

[0018] Please refer to the attached Figure 1 to the attached Figure 4 , the present invention provides a technical solution: a box body 14, having a cavity. A fixed disk 26 is horizontally arranged in the box body 14, dividing the cavity into an installation cavity and a liquid storage cavity up and down. It also includes, Two arc-shaped tooth rings 24 are horizontally arranged on the upper end surface of the fixed disk 26. The extension connection lines of the inner and outer arc surfaces of the two arc-shaped tooth rings 24 respectively enclose a complete circle. Meshing teeth are arranged on the inner and outer arc surfaces of the arc-shaped tooth ring 24. Avoidance openings are arranged at the ends of the two arc-shaped tooth rings 24 close to each other; A fixed block 21 is rotatably arranged on the fixed disk 26. At least one telescopic rod 22 is horizontally arranged on the fixed block 21. The end of the telescopic rod 22 is rotatably connected to a driven gear 23. The driven gear 23 can be meshed with the meshing teeth on the inner and outer arc surfaces of the arc-shaped tooth ring 24 respectively. A stirring shaft 40 is arranged at the lower end of the driven gear 23, and a switching part 25 is arranged above the end of the telescopic rod 22; The limiting disk 30 is horizontally arranged in the installation cavity. A first guiding groove 31 and a second guiding groove 32 are respectively arranged at the edge and the center of the limiting disk 30. The first guiding groove 31 and the second guiding groove 32 are concentrically arranged. The first guiding groove 31 has an opening and bends and extends along the tangent direction of the opening towards the second guiding groove 32 to form a transition groove 33. The intersection of the transition groove 33 is communicated, and the extending end is communicated with the second guiding groove 32. The communicating position of the second guiding groove 32 and the transition groove 33 is arranged corresponding to the avoidance opening. The switching part 25 is in sliding fit with the first guiding groove 31, the second guiding groove 32 and the transition groove 33. During the rotation of the driven gear 23 along with the fixed block 21, the switching part 25 circulates and switches between the first guiding groove 31, the transition groove 33 and the second guiding groove 32 respectively, driving the stirring shaft 40 to rotate self and move radially in the liquid storage cavity at the same time.

[0019] It should be noted that: the box body 14 has a cavity. The fixed disk 26 is horizontally arranged in the box body 14, dividing the cavity into an installation cavity and a liquid storage cavity up and down, providing an installation space and a stirring place for other components. Two arc-shaped tooth rings 24 are horizontally arranged on the upper end surface of the fixed disk 26 and are meshed with the driven gear 23 through the meshing teeth on their inner and outer arc walls, providing a power source for the self-rotation of the stirring shaft 40. The fixed block 21 is rotatably arranged on the fixed disk 26, and at least one telescopic rod 22 is horizontally arranged thereon. The end of the telescopic rod 22 is rotatably connected to the driven gear 23. The driven gear 23 can be meshed with the meshing teeth of the arc-shaped tooth ring 24, thereby driving the self-rotation of the stirring shaft 40. A switching part 25 is arranged above the end of the telescopic rod 22, which is used to switch between the first guiding groove 31, the transition groove 33 and the second guiding groove 32, driving the telescopic rod 22 to stretch and retract, and can also drive the radial movement of the stirring shaft 40 during the switching. The limiting disk 30 is horizontally arranged in the installation cavity. The first guiding groove 31 and the second guiding groove 32 are respectively arranged at its edge and center. The first guiding groove 31 has an opening and bends and extends along the tangent direction towards the second guiding groove 32 to form a transition groove 33. The communicating position of the transition groove 33 and the second guiding groove 32 corresponds to the avoidance opening of the arc-shaped tooth ring 24. Thus, when the switching part 25 slides in the first guiding groove 31, the driven gear 23 is meshed with the inner side of the arc-shaped tooth ring 24. When the switching part 25 slides in the transition groove 33, the driven gear 23 starts to pass through the arc-shaped tooth ring 24 along the avoidance opening. When the switching part 25 slides from the transition groove 33 into the second guiding groove 32, the driven gear 23 slides from the inner side of the arc-shaped tooth ring 24 to the outer side and starts to be meshed with the outer side of the arc-shaped tooth ring 24. While ensuring full stirring of different regions of the colloid, the radial movement during the switching can assist in scraping the bubbles on the surface of the glue, and can also stir the area where bubbles are likely to accumulate on the inner wall of the box body 14, accelerating the rising or bursting of the bubbles in this area to the surface.

[0020] Please refer to the appendix Figure 2 、appendixFigure 4 and the attached Figure 7 , the present invention provides a technical solution: the outer arc wall of the limit disk 30 is fixed to the inner arc wall of the installation cavity, one end of the transition groove 33 far from the guiding groove 31 along its own extending direction is tangent to the inner circle of the guiding groove 32, a limiting groove 34 is opened on the inner side wall of the transition groove 33 far from the fixed disk 26, the width of the limiting groove 34 is smaller than the width of the transition groove 33 and the inner side wall of the transition groove 33 is arranged closer to the fixed disk 26 than the inner side wall of the limiting groove 34, both ends of the limiting groove 34 along the extending direction of the transition groove 33 are respectively communicated with the guiding groove 31 and the guiding groove 32, and wedge-shaped blocks 35 are fixed on the inner side walls of both ends of the limiting groove 34 along the extending direction of the transition groove 33; The switching part 25 includes a fixing plate 251 fixed to the top of the end of the telescopic rod 22 far from the fixed block 21, a first slider 252 is fixed at the center of one side wall of the fixing plate 251 far from the telescopic rod 22, a sliding channel is vertically opened at the center of one side wall of the first slider 252 far from the fixing plate 251, a second slider 253 slides in the sliding channel, a first return spring 254 is fixed at one end of the second slider 253 close to the inner side wall of the sliding channel, the other end of the first return spring 254 is fixed to the bottom inner wall of the sliding channel, the side wall of the second slider 253 far from the first slider 252 is arranged as an inclined surface, the first slider 252 is slidably adapted to the guiding groove 31, the guiding groove 32 and the transition groove 33, and the second slider 253 is slidably adapted to the limiting groove 34.

[0021] It should be noted that: two transition grooves 33 are opened along the tangential direction of the circumferential direction of the guiding groove 31, the two transition grooves 33 are symmetrically arranged with respect to the radial axis of the limit disk 30, the middle parts of the ends of the two transition grooves 33 far from the guiding groove 31 along their extending directions intersect and communicate with each other, the limiting groove 34 is opened in the transition groove 33, and the depth of the limiting groove 34 is deeper and the width is smaller relative to the transition groove 33; The length direction of the fixing plate 251 is the same as the length direction of the telescopic rod 22, one end is fixed to the top of the outer ring of the three-ring bearing, and the other end is fixed to the top of the end of the telescopic rod 22 far from the fixed block 21; Taking the guiding groove 31 as an example, when the first slider 252 slides in the guiding groove 31, the end of the second slider 253 far from the first slider 252 slides and abuts against the inner wall of the guiding groove 31 and cannot pop out of the sliding channel. During this period, the first return spring 254 is continuously compressed. When the fixing plate 251 slides to the connection part of the limiting groove 34 and the guiding groove 31, the second slider 253 can pop out under the action of the first return spring 254 and insert into the limiting groove 34. At this time, a part of the second slider 253 is still located in the sliding channel to ensure its connection strength with the first slider 252; In order to ensure that while the second slider 253 slides into and out of the limit groove 34, the resistance it receives is minimized as much as possible. The inclination angles of the inclined surfaces at the end of the second slider 253 away from the first slider 252 and the inclined surface of the wedge block 35 are complementary. That is, when the second slider 253 slides out of the limit groove 34, the end inclined surface of the second slider 253 abuts against the inclined surface of the wedge block 35, so that the second slider 253 can smoothly retract into the sliding channel.

[0022] Please refer to the attached Figure 3 、the attached Figure 5 Refer to the attached drawings. The present invention provides a technical solution: A plurality of telescopic rods 22 are fixed on the outer arc wall of the fixed block 21 and are distributed in an annular array about the axis of the fixed block 21. The length direction of the telescopic rod 22 is parallel to the radial direction of the fixed block 21 and the telescopic rod 22 can freely expand and contract along its own length direction. A three-ring bearing is fixed at the end of the telescopic rod 22 away from the fixed block 21. The end of the telescopic rod 22 is fixed on the outer arc wall of the outer ring of the three-ring bearing. The driven gear 23 is fixed at the bottom of the middle ring of the three-ring bearing. The fixing plate 251 is fixed on the top of the outer ring and the end of the telescopic rod 22 away from the fixed block 21. A motor 20 is fixed on the top of the limit disc 30. The output end of the motor 20 penetrates through the limit disc 30 and is fixed on the top of the fixed block 21; At the positions corresponding to the four driven gears 23 on the top of the fixed disc 26, inclined chutes are opened. The inclined chutes penetrate through the fixed disc 26 in the vertical direction. A stirring shaft 40 is fixed at the bottom of the driven gear 23. The end of the stirring shaft 40 away from the driven gear 23 penetrates through the inclined chute and is arranged in the liquid storage cavity. A fixed shaft 41 is fixed to the inner ring of the three-ring bearing. The stirring shaft 40 is sleeved outside the fixed shaft 41.

[0023] It should be noted that: The telescopic rod 22 is used to support the driven gear 23, and its own telescopic function is used to adapt to the displacement generated in the radial direction when the driven gear 23 switches the meshing position under the guidance of the switching part 25. While the three-ring bearing ensures the rotation of the driven gear 23, the other components can remain relatively stationary. On the fixed disc 26, the inclined chute on the one hand allows the stirring shaft 40 to penetrate through, and at the same time, when the fixed disc 26 rotates on the inner wall of the box body 14, the driven gear 23 will not be hindered by the fixed disc 26 during its revolution. The orientation of the inclined chute is used to adapt to the synchronous radial movement of the stirring shaft 40 when the driven gear 23 switches.

[0024] Please refer to the attached Figure 5 、the attached Figure 6 、the attached Figure 8 and the attached Figure 9, the present invention provides a technical solution: the top of the fixed shaft 41 is fixed to the top of the telescopic rod 22 through a switching part 25. One end of the outer arc wall of the stirring shaft 40 close to the fixed disk 26 is provided with a rotating groove. The length direction of the rotating groove is consistent with the axial direction of the stirring shaft 40. A rotating plate 42 is rotated in the rotating groove. The length direction of the rotating plate 42 is consistent with the radial direction of the stirring shaft 40. A torsion spring is provided at the rotating connection between the rotating plate 42 and the stirring shaft 40. Sharp bumps are provided on the side wall of the rotating plate 42 along its length direction; Two fixed cylinders 43 distributed in an annular array about the axial direction of the stirring shaft 40 are fixed to one end of the outer arc wall of the stirring shaft 40 far from the fixed disk 26. The axial direction of the fixed cylinder 43 is consistent with the radial direction of the stirring shaft 40. An annular gear disk 45 is fixed at the position corresponding to the fixed cylinder 43 on the outer arc wall of the fixed shaft 41. A bevel gear 46 is meshed and connected at the position corresponding to the fixed cylinder 43 on the top of the annular gear disk 45. A transmission shaft one is fixed on the side wall of the bevel gear 46 far from the annular gear disk 45. A vibration mechanism is fixed at the end of the transmission shaft one far from the annular gear disk 45. The vibration mechanism slides in the fixed cylinder 43; The vibration mechanism arranged in the fixed cylinder 43 includes a housing 50 slidably connected to the side of the inner arc wall of the fixed cylinder 43 far from the bevel gear 46. A second return spring 51 is fixed on the side wall of the housing 50 close to the bevel gear 46. A piston plate 54 is fixed on the side of the second return spring 51 far from the housing 50. The piston plate 54 is rotatably arranged outside the transmission shaft one. The end of the transmission shaft one far from the bevel gear 46 extends into the housing 50. A transmission shaft two is fixed on the side wall of the housing 50 far from the bevel gear 46. A stirring blade 44 is fixed at the end of the transmission shaft two far from the housing 50; Two limiting plates 52 distributed in an annular array about the axial direction of the transmission shaft are fixed on the outer arc wall of the end of the transmission shaft fixed on the bevel gear 46 extending into the housing 50. The limiting plates 52 are integrally spiral and coaxial with the transmission shaft. Two limiting columns 53 distributed in an annular array about the axial direction of the housing 50 are fixed on the inner side wall of the housing 50. The axial direction of the limiting columns 53 is consistent with the radial direction of the housing 50, and the limiting columns 53 are in contact with the limiting plates 52;

[0025] It should be noted that: the rotating plate 42 is mainly used to scrape the bubbles on the surface of the glue. Its rotating connection with the stirring shaft 40 is used for adaptive avoidance when collisions occur between multiple rotating plates 42; Due to the relative fixation of the fixed shaft 41, when the stirring shaft 40 rotates, the bevel gear 46 will rotate around the annular gear disk 45. And due to the meshing of the annular gear disk 45 and the bevel gear 46, the bevel gear 46 rotates self, thereby triggering the vibration mechanism; When the bevel gear 46 rotates, the bevel gear 46 drives the first transmission shaft to rotate. The first transmission shaft drives the limiting plate 52 on its outer arc wall to rotate and pushes the limiting column 53 in the direction away from the bevel gear 46. When the limiting column 53 no longer abuts against the limiting plate 52, the housing 50 will pop out under the action of the second reset spring 51, so that the stirring blade 44 reciprocates in the radial direction of the stirring shaft 40 to achieve a vibrating effect. The piston plate 54 is fixed on the inner arc wall of the fixed cylinder 43.

[0026] Working principle: When the equipment is working, the output end of the motor 20 drives the fixed block 21 to rotate. A plurality of telescopic rods 22 are horizontally arranged on the fixed block 21. The end of the telescopic rod 22 is rotatably connected to the driven gear 23. The driven gear 23 is connected to the stirring shaft 40 below. The stirring shaft 40 penetrates through the inclined chute on the fixed disk 26 into the liquid storage cavity. Two arc-shaped toothed rings 24 are horizontally arranged on the upper end surface of the fixed disk 26. There are meshing teeth on their inner and outer arc surfaces. Avoidance openings are arranged at the ends where the two arc-shaped toothed rings 24 are close to each other. A switching part 25 is arranged above the end of the telescopic rod 22, including a fixing plate 251, a first slider 252, a second slider 253, etc. The limiting disk 30 is horizontally arranged in the installation cavity. A first guiding groove 31 and a second guiding groove 32 are respectively arranged at the edge and the center of the limiting disk 30. The two are concentric. The first guiding groove 31 has an opening and bends and extends along the tangential direction to form a transition groove 33. The connection between the transition groove 33 and the second guiding groove 32 corresponds to the avoidance opening. A limiting groove 34 and a wedge-shaped block 35 are arranged on the inner side wall of the transition groove 33. The switching part 25 circulates and switches between the first guiding groove 31, the transition groove 33, and the second guiding groove 32, driving the driven gear 23 to mesh with different positions of the arc-shaped toothed ring 24, so that the stirring shaft 40 rotates and moves radially at the same time, fully stirring the glue, and can assist in scraping the bubbles on the surface of the glue, stirring the area where bubbles are likely to gather on the inner wall of the box body 14, accelerating the rise or rupture of the bubbles. A rotating plate 42 is arranged on the outer arc wall of the stirring shaft 40 near one end of the fixed disk 26 for scraping the bubbles on the surface of the glue; a fixed cylinder 43 is fixed at the end away from the fixed disk 26. An annular toothed disk 45 is arranged on the outer arc wall of the fixed shaft 41 and meshes with the bevel gear 46. The rotation of the bevel gear 46 drives the first transmission shaft and the limiting plate 52 to rotate, pushing the limiting column 53, so that the housing 50 pops out under the action of the second reset spring 51, driving the stirring blade 44 to reciprocate in the radial direction of the stirring shaft 40 to generate vibration, enhancing the stirring effect, improving the quality of the glue, and ensuring the smooth progress of the glue coating operation.
