Technical Field

[0004] Currently, the photovoltaic industry mainly uses perforated transparent tape to seal the edges of double-glass modules. Double-glass modules are sealed using a double-glass edge sealing machine, which fits the upper and lower layers of glass together and then enters a laminator for lamination. After lamination, the edge sealing tape is removed using an edge tearing machine. However, edge sealing with edge sealing tape cannot be recycled and is relatively expensive. At the same time, edge sealing with tape is prone to edge collapse in double-glass modules, and the upper and lower layers of glass cannot be properly bonded and limited, resulting in poor edge sealing of double-glass modules. Secondly, the tape sticks to the double-glass module, and its bonding strength is relatively high, making it difficult to remove the tape later, or the tape may not be removed cleanly. In addition, the torn tape takes up a lot of space and needs to be processed later. The edge sealing machine for double-glass modules needs to seal the four sides of the double-glass module in turn, and its edge sealing efficiency needs to be improved.

DETAILED DESCRIPTION

[0038] The technical solution of the present disclosure is further described in detail below with reference to the accompanying drawings, but the protection scope of the present disclosure is not limited to the following.

[0039] Embodiment 1, as shown in Figures 1 to 4, a new card slot structure for double glass edge sealing, including an elastic card slot strip 1 and a pull rod 2, the elastic card slot strip 1 includes a vertical edge 3 and a side edge 4, the top and bottom of the vertical edge 3 are integrally formed with the side edge 4, the side edge 4 is inclined toward the mid-perpendicular line of the vertical edge 3, the vertical edge 3 and the two side edges 4 form a triangular structure with a clamping opening, the outer side surface of the side edge 4 is provided with a plurality of locking grooves 5 along its own length direction, the elastic card slot strip 1 has a certain elasticity, and its shape is similar to a book clip, and the elastic card slot strip 1 has a certain elasticity. The groove strips 1 have different length types. When sealing the edges, the elastic groove strips 1 of the corresponding length are selected according to the length of each side of the double-glass component for edge sealing. The pull rod 2 includes two elastically connected cross bars 10. The bottom of the cross bar 10 is fixedly connected with a lock hook 6. The four sides of the double-glass component are all clamped with elastic groove strips 1. The pull rod 2 is used to connect the two opposite elastic groove strips 1. Among them, the lock hook 6 is against the side wall of the locking groove 5. The elastic groove strips 1 are pulled up and down, and the elastic groove strips 1 are made to be elastic by using their own elasticity. The clamping mouth is expanded and clamped on the side of the double-glass component, and the elasticity of the elastic card slot strip 1 is used to clamp the double-glass component. The elastic card slot strips 1 are clamped on the four sides of the double-glass component, and then the two parallel elastic card slot strips 1 are connected together through the pull rod 2, so that the locking hooks 6 at both ends of the pull rod 2 are respectively against the locking grooves 5 of the two elastic card slot strips 1. Since the pull rod 2 is formed by two elastically connected cross bars 10, the elasticity of the pull rod 2 is used to make the locking hooks 6 press against the inner side wall of the locking groove 5, and the action of the pull rod 2 is used. Connecting two parallel elastic card slot strips 1 together with force can limit the position of the elastic card slot strips 1, improve the edge sealing stability of the elastic card slot strips 1, and avoid slipping. When the double-glass component is pressed and laminated, remove the pull rod 2 and the elastic card slot strip 1 in turn. The pull rod 2 and the elastic card slot strip 1 can be recycled, which greatly reduces the cost. At the same time, the edge sealing strength is improved by the dual methods of clamping and limiting. During the transportation of the double-glass component, the elastic card slot strip 1 will not slip, thereby improving the edge sealing effect.

[0040] Embodiment 2, as shown in Figures 1, 2 and 3, the strength of the connection method in which the lock hook 6 is tightly pressed against the inner wall of the locking groove 5 needs to be further improved, mainly because this method has a high assembly accuracy for the pull rod 2. If the abutting positions of the lock hooks 6 at both ends of the pull hook 2 are not synchronized, the elastic force of the pull rod 2 will be uneven, and the pull rod 2 will slide out of the elastic card slot strip 1, thereby affecting the limit of the elastic card slot strip 1. At the same time, the detached pull rod 2 will also affect the double-glass component and the production of the double-glass component. For this reason, it is necessary to improve the connection strength between the pull rod 2 and the elastic card slot strip 1. Therefore, in embodiment 2, the lock hook 6 at both ends of the pull hook 2 is not synchronized, resulting in uneven elastic force on the pull rod 2. On the basis of one, the locking hook 6 includes a vertical body 7 and a horizontal body 8. One end of the vertical body 7 is connected to the cross bar 10, and the other end is connected to the horizontal body 8. The vertical body 7 and the horizontal body 8 are connected to form an L-shaped lock body. The side 4 is provided with a plurality of card slots 9 on the side wall of the locking groove 5. The plurality of card slots 9 are evenly distributed around the circumference of the locking groove 5. The horizontal body 8 is adapted in one of the card slots 9, and the vertical body 7 is against the inner wall of the locking groove 5. At the same time, the horizontal body 8 is inserted into the card slot 9, which limits the vertical freedom of the pull rod 2, improves the connection strength between the pull rod 2 and the elastic card slot strip 1, and prevents the pull rod 2 from detaching and affecting the production of double-glass components.

[0041] Furthermore, as shown in Figures 3 and 4, the tie rod 2 also includes an eccentrically arranged intermediate connecting rod 11, that is, the intermediate connecting rod 11 is eccentrically connected to the two cross bars 10. Since the four sides of the double-glass component are all clamped with elastic card slots 1, two tie rods 2 are required for reinforcement. The two tie rods 2 are both located above the double-glass component for installation. Therefore, the two tie rods 2 will intersect at the center position of the double-glass component. In order to avoid interference between the two tie rods 2, the intermediate connecting rod 11 is eccentrically connected to the cross bar 10, and the eccentric positions of the intermediate connecting rods 11 on the two tie rods 2 are staggered up and down, so that the intersection position of the two tie rods 2 passes through the middle The upper and lower connecting rods 11 are staggered to avoid each other to ensure that the two pull rods 2 do not interfere with each other. One end of the cross bar 10 is provided with a small diameter slot 12 and a large diameter slot 13 in sequence along its own length direction. The two ends of the middle connecting rod 11 are respectively slidably adapted in the small diameter slots 12 of the two cross bars 10, and a limiting ring 14 is slidingly provided in the large diameter slot 13. The middle connecting rod 11 is fixedly connected to the limiting ring 14. The end of the limiting ring 14 away from the middle connecting rod 11 is connected to a spring 15. The end of the spring 15 away from the limiting ring 14 is fixedly connected to the cross bar 10. Two external limiting rings 55 are fixed on the middle connecting rod 11. When the two cross bars When the rod 10 contacts the two external limit rings 55 respectively, the spring 15 is in a stretched state, and the angle between the horizontal body 8 and the vertical body 7 is an obtuse angle, so that the horizontal body 8 can be smoothly inserted into the card slot 9. When in use, the two horizontal rods 10 are pulled apart to expand the distance between the two locking hooks 6. This process will continue to stretch the spring 15, and then the two locking hooks 6 are respectively placed in the locking grooves 5 of the two elastic card slot strips 1. At this time, under the action of the spring 15, the two horizontal rods 10 are moved closer to each other and reset, so that the vertical body 7 is pressed against the inner side wall of the locking groove 5, and the horizontal body 8 is inserted into the card slot 9, thereby connecting the pull rod 2 to the elastic card slot strip 1. Connecting them together can avoid the situation of separation during production and ensure the stability of the edge sealing of the double-glass component; the setting of the limit ring 14 can ensure that the two cross bars 10 will not separate, which means that the length of the pull rod 2 has a certain range. In actual production, the pull rod 2 has different design lengths. The matching pull rod 2 is selected according to the size of the double-glass component, so that the pull rod 2 can smoothly connect the two elastic card groove strips 1. The setting of the external limit ring 55 prevents the two cross bars 10 from contacting each other, so that the middle part of the pull rod 2 is located on the middle connecting rod 11, thereby avoiding the problem of interference between the two pull rods 2 during assembly.

[0042] Example 3. On the basis of Example 2, as shown in Figures 1 and 2, both ends of the elastic card slot strip 1 are provided with a cut surface 16, and the cut surface 16 is inclined at 45 degrees toward the mid-perpendicular line of the elastic card slot strip 1. A number of small holes 17 are opened through the vertical edge 3. Through the setting of the cut surface 16, there will be no interference between the elastic card slot strips 1 on the four side walls of the double-glass component. At the same time, the side edges of the double-glass component can be fully wrapped for edge sealing, further improving the edge sealing effect; since a colloid sealing connection is provided between the upper glass and the lower glass in the double-glass component, the colloid will overflow during the lamination process, and the small holes 17 provide a space for the colloid to overflow, thereby not affecting the lamination operation.

[0043] Embodiment 4: Since the present disclosure provides a new edge sealing method, this method abandons the traditional tape edge sealing method and uses a card clamping method for edge sealing, so that the edge sealing component can be recycled. Traditional edge sealing machines all perform automatic edge sealing on tape. Therefore, traditional edge sealing machines cannot be used directly, that is, the elastic card slot strips cannot be assembled on the double-glass components. Therefore, it is necessary to improve the traditional edge sealing machine according to the edge sealing characteristics of the elastic card slot strips 1. To this end, as shown in Figures 5 to 14, a double-glass edge sealing machine is provided for installing the above-mentioned card slot structure, including a frame, a card slot mounting assembly and a pull rod mounting assembly. The frame includes a hollow machine base 18 and a rectangular frame 45. The rectangular frame 45 is fixed to the top of the hollow machine base 18 Two sets of conveyor belts 19 are arranged in parallel on the hollow machine base 18. A slot mounting assembly and a jacking limit mechanism are respectively arranged above and below the conveyor belt 19. A pull rod mounting assembly is arranged above the slot mounting assembly. An edge sealing station is provided in the middle of the hollow machine base 18. The edge sealing station is a hollow rectangular shape. There are four groups of slot mounting assemblies. The four groups of slot mounting assemblies are arranged around the four sides of the edge sealing station. The four groups of slot mounting assemblies are used to install elastic slot strips 1 on the four sides of the double-glass component respectively. The slot mounting assembly includes two clamping plates 20 arranged opposite to each other in the upper and lower directions. The clamping plate 20 has the freedom to move along the height direction of the hollow machine base 18. A plurality of positioning columns 2 are evenly distributed along the length direction of the clamping plate 20. 1, multiple positioning posts 21 are adapted to multiple locking grooves 5 in a one-to-one correspondence, and the side walls of the positioning posts 21 are slidably penetrated with a snap-in piece 22, which is adapted to one of the slots 9; the double-glass components are loaded on the conveyor belt 19, and the double-glass components are conveyed to the edge sealing station by the conveyor belt 19, so that the four groups of slot installation components are respectively facing the four sides of the double-glass components, and the two clamping plates 20 act on the upper end face and the lower end face of the elastic slot strip 1 respectively, so that the positioning posts 21 are adapted to the locking groove 5 to complete the positioning, and the snap-in piece 22 is adapted to the slot 9 to complete the connection between the clamping plate 20 and the elastic slot strip 1, and then the two clamping plates 20 move in opposite directions, that is, the upper clamping plate 20 moves upward and the lower clamping plate 20 moves downward, thereby The clamping mouth of the elastic card slot strip 1 is pulled open, and the clamping mouth is moved to correspond to the elastic card slot strip 1 of the double-glass component. After the elastic card slot strip 1 corresponds to the side of the double-glass component, the upper clamping plate 20 moves downward, and the lower clamping plate 20 moves upward, so that the elastic card slot strip 1 is reset and clamped on the side of the double-glass component. The four groups of card slot installation components operate synchronously, thereby sealing the four sides of the double-glass component at the same time, improving the edge sealing efficiency. Then, the card connecting piece 22 slides out of the card slot 9 to unlock the connection state between the elastic card slot strip 1 and the clamping plate 20. At this time, the upper clamping plate 20 moves upward, and the lower clamping plate 20 moves downward, so that the card slot installation assembly is separated from the double-glass component, thereby leaving the elastic card slot strip 1 on the double-glass component to complete the edge sealing;It should be noted that the opening of the elastic slot strip 1 is wider than the thickness of the double-glass module. This ensures that the elastic slot strip 1 does not contact the double-glass module during assembly, preventing scratches. The elastic slot strip 1 utilizes a non-contact assembly method, ensuring that the double-glass module is not damaged during the edge sealing process. Furthermore, the elastic slot strip 1 moves directly against the side of the double-glass module for assembly, rather than sliding in from one end. This significantly shortens the movement distance and range of the elastic slot strip 1, reducing space requirements. This also reduces assembly time and improves edge sealing efficiency.

[0044] After the above-mentioned elastic slot strips 1 are assembled to the double-glass component, the pull rods 2 need to be assembled next. The pull rods 2 are assembled through the pull rod installation assembly. Since the double-glass component is equipped with four elastic slot strips 1, there are two sets of parallel elastic slot strips 1. Each set requires one or two pull rods 2 for connection. Since the elastic slot strips 1 themselves have strong edge sealing strength, in order to reduce the assembly process and save materials, each set of elastic slot strips 1 uses one pull rod 2 for reinforced positioning, that is, four elastic slot strips 1 need to be connected using two pull rods 2. Specifically, as shown in Figures 9 and 11, the pull rod installation assembly includes a horizontal plate 23, and a left slide 24 and a right slide 25 are slidingly provided on the horizontal plate 23. The left The moving direction of the slide 24 is opposite to that of the right slide 25. Finger cylinders 26 are provided on both the left slide 24 and the right slide 25. The two finger cylinders 26 respectively clamp the two cross bars 10 on the pull rod 2. The left slide 24 and the right slide 25 move synchronously to pull the two cross bars 10 apart, expand the space between the two locking hooks 6, and then the horizontal plate 23 clamps the pull rod 2 and moves close to the double-glass component, so that the two locking hooks 6 are respectively located in the locking grooves 5 of the two elastic card slot strips 1. Then, the left slide 24 and the right slide 25 move back synchronously, so that the locking hooks 6 are pressed against the inner side wall of the locking groove 5 under the reaction force of the spring 15, and the horizontal body 8 is inserted into the card slot 9 to strengthen the connection, thereby completing the entire edge sealing process of the double-glass component.

A limiting chute 30 communicating with the driving cavity 27 is formed in the side wall of the positioning column 21. The clamping piece 22 is slidably fitted in the limiting chute 30. The bottom of the clamping piece 22 is connected to the inner bottom wall of the driving cavity 27 through a tension spring 53. A wedge surface 31 is provided on the side of the clamping piece 22 close to one end of the driving disc 28. The width of the clamping piece 22 at the wedge surface 31 gradually increases in the direction away from the driving disc 28. A convex block 32 is fixed to the side wall of the driving disc 28. The wedge surface 31 is located on the rotation path of the convex block 32. The transmission shaft 29 passes through the clamping plate 20 and is connected to a gear 33. A straight rack 34 is slidably arranged on the clamping plate 20. The gear 33 meshes with the straight rack 34. A first cylinder 35 is horizontally arranged on the clamping plate 20. The telescopic shaft of the first cylinder 35 is connected to the straight rack 34. One end of the clamping plate 20 far from the straight rack 34 is connected to a lifting frame 36. The lifting frame 36 is in a U shape. The lifting frame 36 is hinged to the telescopic shaft of a second cylinder 37. The second cylinder 37 is vertically arranged. The cylinder body of the second cylinder 37 is installed on the slide of a linear driving module 38. The linear driving module 38 is installed on the frame. The slide of the linear driving module 38 moves along the direction perpendicular to the clamping plate 20. The linear driving module 38 located below the double-glass component is installed on the hollow base 18. The linear driving module 38 located above the double-glass component is installed on a rectangular frame 45. The slot installation component further includes two slot storage plates 39 arranged in parallel along the horizontal direction. The slot storage plates 39 are connected to the frame by bolts. The slot storage plates 39 are located between the two clamping plates 20 in the height direction.

A triangular limiting groove 40 is formed in the top surface of the slot storage plate 39 along its own length direction. The cross section of the triangular limiting groove 40 is an isosceles right triangle shape. The two ends of the elastic slot strip 1 are respectively fitted in the triangular limiting grooves 40 of the two slot storage plates 39. An operation space for the slot installation component is left between the two slot storage plates 39. The elastic slot strip 1 is stored on the slot storage plate 39, so that the two ends of the elastic slot strip 1 are fitted in the triangular limiting grooves 40, and the clamping opening of the elastic slot strip 1 faces the side of the double-glass component, completing the positioning of the elastic slot strip 1. Thus, it is not necessary to adjust the position of the elastic slot strip 1 along the length direction of the side of the double-glass component. Only need to pull open the elastic slot strip 1 and then move the elastic slot strip 1 towards the double-glass component for assembly, making the assembly of the elastic slot strip 1 simpler and faster;The specific process of assembling the elastic card slot strip 1 through the card slot installation assembly is as follows: the linear drive module 38 drives the clamping plate 20 to move close to or away from the double-glass component, first making the clamping plate 20 correspond to the elastic card slot strip 1 on the card slot storage plate 39 closest to the double-glass component, and then the second cylinder 37 extends to drive the clamping plate 20 to move close to the elastic card slot strip 1, so that the clamping plate 20 contacts the elastic card slot strip 1, due to the hinge of the lifting frame 36, the clamping plate 20 will adapt to the corresponding deflection of the oblique surface of the elastic card slot strip 1, until the clamping plate 20 completely contacts the elastic card slot strip 1, the positioning column 21 is located in the locking groove 5, and then the two clamping plates 20 move up at the same time to remove the elastic card slot strip 1 from the triangular limit groove 40. At this time, the elastic card slot strip 1 is facing the side of the double-glass component, and then the first cylinder 35 starts to drive the spur rack 34 to move, and the spur rack 34 is synchronously The gears 33 are driven to rotate, which in turn drive the transmission shaft 29, which in turn drives the drive disc 28. The drive disc 28 drives the protrusion 32 to rotate close to the wedge surface 31. The protrusion 32 presses the wedge surface 31 of the clamping piece 22, thereby pushing the clamping piece 22 to stretch the tension spring 53 and move it out of the limiting slot 30, allowing the clamping piece 22 to insert into the clamping slot 9, completing the connection between the clamping plate 20 and the elastic clamping strip 1. The first cylinder 35 stops operating, thereby locking the position of the spur rack 34 and the clamping piece 22. The second cylinder 37 is then activated, driving the clamping plate 20 to move away from the clamping slot storage plate 39, thereby opening the clamping opening of the elastic clamping strip 1. The linear drive module 38 then drives the elastic clamping strip 1 to move close to the side of the double-glass assembly, thereby assembling the elastic clamping strip 1 on the side of the double-glass assembly.

[0046] Embodiment 6. On the basis of embodiment 5, as shown in Figures 9 to 13, the pull rod installation assembly also includes a transverse linear drive module 43, a longitudinal linear drive module 56, two storage plates 57 arranged in parallel in the horizontal direction, and two pull rod storage plates 41 arranged in parallel in the horizontal direction. The storage plates 57 are perpendicular to the pull rod storage plates 41. The structure of the storage plates 57 is the same as that of the pull rod storage plates 41. The transverse linear drive module 43 is installed on the rectangular frame 45, and the longitudinal linear drive module 56 is installed on the slide of the transverse linear drive module 43.

The bottom of the rotating machine base 58 is rotatably connected to a switching shaft 59. The switching The shaft 59 is fixedly connected to the horizontal plate 23, and the rotating machine base 58 has a built-in switching motor. The output shaft of the switching motor is connected to the switching shaft 59. The top surface of the pull rod storage plate 41 is evenly provided with multiple storage grooves 42 along its own length direction. The two ends of the pull rod 2 are respectively adapted in the storage grooves 42 of the two pull rod storage plates 41. The horizontal plate 23 is provided with a screw groove 46 along its own length direction. A bidirectional threaded screw 47 is rotatably connected in the screw groove 46. The left slide 24 and the right slide 25 are respectively threadedly mounted on the two threaded segments of the bidirectional threaded screw 47 with opposite rotation directions. A motor 54 is provided at one end of the horizontal plate 23. The output shaft of the motor 54 is connected to one end of the bidirectional threaded screw 47 through the horizontal linear drive module 43 and the longitudinal linear drive module 56. The horizontal plate 23 is made to have linear movement freedom in the X and Y directions in the horizontal direction, so that the pull rod 2 on the pull rod storage plate 41 can be assembled on the elastic card slot strip 1, and the pull rod 2 is limited by the storage slot 42, and then the two pull rods 2 are installed in sequence. It should be noted that the pull rod on the pull rod storage plate 41 or the pull rod on the storage plate 57 can be installed first. Specifically, the switching motor drives the switching shaft 59 to rotate, and the switching shaft 59 drives the horizontal plate 23 to rotate, so that the horizontal plate 23 is perpendicular to the storage plate 57 to install the pull 2 ​​thereon, and then the horizontal plate 23 is perpendicular to the pull rod storage plate 41 to install the pull rod 2 thereon, so that the horizontal plate can assemble the storage plate 57 and the pull rod on the pull rod storage plate 41 to the double-glass component in turn, driven by the horizontal linear drive module. The cooperation between 43 and the longitudinal linear drive module 56 enables the horizontal plate 23 to correspond to the pull rod 2 at different positions, and then the height position of the horizontal plate 23 is adjusted by the extension and contraction of the third cylinder 44, so that the two finger cylinders 26 respectively clamp the two cross bars 10 of the pull rod 2, and then the motor 54 is started, and the motor 54 drives the bidirectional threaded screw 47 to rotate. Since the thread rotation direction of the left slide 24 is opposite to that of the right slide 25, the movement directions of the left slide 24 and the right slide 25 are opposite, and then the two cross bars 10 on the pull rod 2 are synchronously driven to move to adjust the distance between the two locking hooks 6, and then the locking hook 6 on the horizontal plate 23 is driven by the third cylinder 44 to move into the locking groove 5, and then the motor 54 is reversed to make the left slide 24 and the right slide 25 reset and move.This causes the lock hook 6 to move closer to the inner wall of the locking groove 5, and then the transverse body 8 is inserted into the card groove 9. Finally, the finger cylinder 26 releases the cross bar 10 to complete the assembly of the pull rod 2. After the assembly is completed, the pull rod installation assembly is reset.

When the double-glass component is transported to the edge sealing position by the conveyor belt 19, the jacking cylinder 51 extends to drive the jacking plate 48 to rise, and the jacking plate 48 pushes the double-glass component to move close to the upper limit column 49, so that the double-glass component contacts the upper limit column 49, so that the double-glass component The component rises to the top of the card slot storage plate 39, and at the same time, the four sides of the double-glass component are completely exposed, so that the four elastic card slot strips 1 can be assembled on the four side edges of the double-glass component at the same time, and the lifting plate 48 and the upper limit column 49 respectively abut against the lower end surface and the upper end surface of the double-glass component, thereby limiting the double-glass component and ensuring that there is no offset between the upper glass and the lower glass during the edge sealing process. When the edge sealing is completed, the lifting cylinder 51 contracts and drives the double-glass component to reset downward, so that the double-glass component acts on the conveyor belt 19, and the double-glass component with completed edge sealing is sent out by the conveyor belt 19, and then the above process is repeated to continue edge sealing the next double-glass component, completing the automated edge sealing operation of the double-glass component.

[0048] In summary, the present invention abandons the traditional tape edge sealing method and adopts reusable elastic card slot strips 1 for edge sealing.

Industrial Applicability

When the double-glass component is pressed and laminated, the pull rod and the elastic slot strip are removed in turn, and the pull rod and the elastic slot strip can be recycled, which greatly reduces the cost. At the same time, the edge sealing strength is improved by the dual methods of clamping and limiting. During the transportation of the double-glass component, the elastic slot strip will not slip, thereby improving the edge sealing effect.

Then the two clamping plates move in opposite directions, thereby opening the clamping mouth of the elastic card slot strip, and moving the elastic card slot strip with the clamping mouth corresponding to the double-glass component, so that the elastic card slot strip is clamped on the side of the double-glass component. The four groups of card slot installation components operate synchronously, thereby sealing the four sides of the double-glass component at the same time, thereby improving the edge sealing efficiency.
