Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component production equipment design, in particular to a position-adjustable battery sheet glue dot printing screen. Background Art

[0002] After the welding ribbon of the main grid-less battery cell is welded to the battery cell, since there is no firm connection point on the surface of the battery cell, a new process is proposed in the relevant technology for printing glue dots on the surface of the battery cell before and after the battery cell is welded to ensure the firm adhesion of the welding ribbon and the battery cell and prevent the welding ribbon from being disconnected from the surface of the battery cell. When printing glue dots on the surface of the battery cell, it is necessary to confirm the position of the battery cell before printing the glue dots. The traditional method is to align the battery cell after detecting the position of the battery cell and then apply glue. However, after the battery cell is welded into a string, it is no longer convenient to align it. Therefore, an adjustment mechanism that can adjust the printing position is required to adapt to the actual position of the battery cell.

[0003] Currently, the main method for adjusting the printing screen on the market is to use the corresponding servo module to control the movement of the screen as a whole. However, in this method, the printing screen drive occupies a large space. The more positions and directions that need to be adjusted, the more complex the corresponding drive becomes, which is not conducive to installation and rapid adjustment. Utility Model Content

[0027] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. In the figures, regions and layer thicknesses are exaggerated for clarity. Identical reference numerals in the figures denote identical or similar structures, and thus detailed descriptions thereof will be omitted.

[0028] The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be employed. In other cases, well-known structures, materials or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0029] The following example describes an embodiment of the present invention's position-adjustable solar cell glue dot printing screen. This example is only a partial embodiment of the present invention, but the scope of protection of the present invention is not limited to this embodiment. All other embodiments obtained by persons of ordinary skill in the art without inventive effort are intended to fall within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 8 According to an embodiment of the present invention, a position-adjustable battery cell glue point printing screen is provided, comprising an outer frame 10 and a first mounting plate 11, a second mounting plate 12 and a third mounting plate 13 arranged in layers from top to bottom, wherein the outer frame 10 and the first mounting plate 11, the first mounting plate 11 and the second mounting plate 12, and the second mounting plate 12 and the third mounting plate 13 are all slidably connected, and the first mounting plate 11 can be driven to move linearly along a first direction, the second mounting plate 12 can be driven to move linearly along a second direction, the second direction is perpendicular to the first direction, the third mounting plate 13 can be driven to rotate in a horizontal plane, and a printing screen 14 is connected to the bottom end surface of the third mounting plate 13. It can be understood that the printing screen 14 is a box structure with an upper opening, and a plurality of mesh holes are formed on the bottom wall of the box structure. When the box structure is filled with glue, it can leak from each through hole to the corresponding position of the battery cell below to form glue spots.

[0031] In this technical solution, the position of the printing screen 14 connected to the bottom end face of the third mounting plate 13 is adjusted on the horizontal plane by arranging the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 in upper and lower layers and then displacing each layer of the plate in different directions of freedom, thereby simplifying the difficulty of controlling the position adjustment of the printing screen 14. Moreover, since each corresponding mounting plate is driven independently, the space occupied by the driving components can be effectively reduced, which facilitates the installation and use of parts.

[0032] The first direction is, for example, an X-axis direction in an XOY plane coordinate system, and the second direction is correspondingly a Y-axis direction. The rotation of the third mounting plate 13 is a rotation around point O.

[0033] In a specific embodiment, a first linear motor 101 is provided between the outer frame 10 and the first mounting plate 11, the stator of the first linear motor 101 is fixed to the outer frame 10, and the mover of the first linear motor 101 is fixedly connected to the first mounting plate 11, so that the first mounting plate 11 can be driven to move linearly along a first direction for a preset distance when the outer frame 10 is stationary. The outer frame 10 and the first mounting plate 11 are also slidably connected by a first slide rail assembly 102 to reliably guide the linear movement of the first mounting plate 11. It can be understood that the aforementioned first slide rail assembly 102 can specifically adopt a commercially available slide rail assembly, which can be configured in multiple groups, and each group of the first slide rail assembly 102 can be respectively provided in the four corner areas of the top surface of the first mounting plate 11.

[0034] In a specific embodiment, a second linear motor 111 is provided between the first mounting plate 11 and the second mounting plate 12, and the stator of the second linear motor 111 is fixedly connected to the first mounting plate 11, and the mover of the second linear motor 111 is fixedly connected to the second mounting plate 12, so that the second mounting plate 12 can be driven to move linearly a preset distance relative to the first mounting plate 11 along a second direction. The first mounting plate 11 and the second mounting plate 12 are slidably connected by a second slide rail assembly 112. The second slide rail assembly 112 can be the same as the first slide rail assembly 102 in structure, except that the installation position and guide direction are different, which will not be elaborated here, but it can be understood that the sliding guide trajectories of the first slide rail assembly 102 and the second slide rail assembly 112 are both straight lines.

[0035] In a preferred embodiment, the first linear motor 101 has two groups, and the two groups of the first linear motor 101 are respectively arranged on the side edges of the first mounting plate 11 parallel to the first direction; the second linear motor 111 has two groups, and the two groups of the second linear motor 111 are respectively arranged on the side edges of the second mounting plate 12 parallel to the second direction.

[0036] In this technical solution, two groups of the first linear motor 101 and the second linear motor 111 are provided, which can further reduce the space occupied by the driving components in the device and is conducive to the compact design of the device.

[0037] In some embodiments, a third linear motor 121 is provided between the second mounting plate 12 and the third mounting plate 13, the stator of the third linear motor 121 is fixedly connected to the second mounting plate 12, the mover of the third linear motor 121 is fixedly connected to the third mounting plate 13, and the second mounting plate 12 and the third mounting plate 13 are slidably connected via a third slide rail assembly 122, the sliding guide trajectory of the third slide rail assembly 122 is an arc, and the motion trajectory of the mover of the third linear motor 121 is concentric with the sliding guide trajectory of the third slide rail assembly 122, that is, objectively, the displacement drive trajectory of the third linear motor 121 is an arc, which is an arc-shaped linear motor, which is different from the displacement drive trajectory of the aforementioned first linear motor 101 and the second linear motor 111, which are straight lines. The aforementioned differences can be met by selecting existing linear motors.

[0038] Similar to the arrangement of the first linear motor 101 and the second linear motor 111 , the third linear motor 121 also has two groups, and the two groups of the third linear motor 121 are respectively located at two opposite side edges of the second mounting plate 12 .

[0039] As a preferred embodiment, the printing screen 14 is detachably connected to the third mounting plate 13 to facilitate the use and maintenance of the printing screen 14 .

[0040] See Figure 8As shown, in a specific embodiment, a snap-in groove 131 with parallel intervals on the left and right is formed on the bottom end surface of the third mounting plate 13, and a snap-in slider 141 with parallel intervals on the left and right is provided on the printing screen 14. Each of the snap-in sliders 141 is respectively slidably connected to each of the snap-in grooves 131 and forms a limiting connection in the thickness direction of the third mounting plate 13 and a sliding connection in the horizontal direction (that is, on the horizontal plane in use). In this technical solution, the aforementioned printing screen 14 can be positioned, assembled and disassembled with the third mounting plate 13 by a push-pull method in the horizontal plane (for example, when the mesh holes of the printing screen are blocked and need to be cleaned and maintained), and the operation is very convenient.

[0041] See Figure 6 As shown, the first end of the third mounting plate 13 has a limit block 132, and the limit block 132 is located on the sliding path of the printing screen 14, so as to be able to form a limiting positioning purpose of the sliding position of the printing screen 14 during the assembly process with the third mounting plate 13; further, the second end of the third mounting plate 13 has a locking hook 133, so as to be able to lock the position of the sliding assembled printing screen 14 into place, specifically, one end of the locking hook 133 is threadedly connected to the second end of the third mounting plate 13 through a locking pin 134, and at the same time, a corresponding boss 142 is provided at the corresponding position of the printing screen 14, and the locking hook 133 can be hooked with the boss 142, and the final position of the locking hook 133 is achieved by screwing the locking pin 134 into place.

[0042] In some embodiments, the outer frame 10 is further provided with a plurality of height limiting columns 103, and each of the height limiting columns 103 is arranged at intervals around the outer frame 10 to limit the minimum relative height between the printing screen and the battery cell below, thereby preventing the printing screen 14 from contacting the top surface fascia of the battery cell and preventing the smooth formation of glue points.

[0043] A first grating scale reading mechanism (not shown and not labeled in the figure) is also provided between the outer frame 10 and the first mounting plate 11, and a second grating scale reading mechanism (not shown and not labeled in the figure) is also provided between the first mounting plate 11 and the second mounting plate 12, so as to monitor and feedback-adjust the real-time positions of the first mounting plate 11 and the second mounting plate 12, and detect the offset position distance through the grating scale to ensure the accuracy of the corresponding linear motor position movement.

[0044] As can be understood, the aforementioned printing screen 14 is shaped like a hollow box. The outer frame 10, first mounting plate 11, second mounting plate 12, and third mounting plate 13 have a central hollow opening. The interior of the printing screen 14 is used to hold the glue. The bottom of the printing screen 14 is formed with a plurality of mesh holes (not labeled in the figure) arranged in an array. These holes are used to apply the glue to the surface of the cell when scraped by a squeegee. In a preferred embodiment, a protective cover 16 is provided around the exterior of the aforementioned device.

[0045] When the printing screen of the present invention is in use, the angle and offset position of the battery cell conveyed by the front streamline are first detected, and then its own position is adjusted. After it is adjusted to the position corresponding to the position of the corresponding battery cell, the corresponding scraper mechanism is activated to enable the screen to leak glue and finally achieve the dispensing effect.

[0046] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
