Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component processing, in particular to an adhesive tape clamping mechanism. Background Art

[0002] In the stringing process of photovoltaic modules, a tape clamping mechanism (also called a tape puller) is required to clamp the free end of the tape and then pull it out to a preset length so that it can be cut to form a tape segment of a preset length. The tape clamping mechanism can be controlled to approach or move away from the corresponding cutting and pressing mechanism to complete the clamping and pulling of the tape. In the prior art, the corresponding tape clamping mechanism has an upper clamping jaw and a lower clamping jaw that can approach to form a clamp for the tape. One of the upper and lower clamping jaws is fixed in position, that is, it cannot be controlled to open and close, while the other can be controlled to approach or move away from the fixed clamping jaw to open and close. Since the tape is relatively soft, after the previous cutting process is completed, the free end of the tape will sink under the action of its own weight or warp under the action of its own internal stress. When the tape clamping mechanism approaches the free end of the tape for clamping, the deviation of the position of the free end of the tape makes it unable to enter the clamping area of ​​the upper and lower clamping jaws, which causes the tape clamping mechanism to fail to clamp the end of the tape, thereby reducing the working efficiency.

[0005] In some embodiments, both the upper chuck and the lower chuck are configured with an open slot, the opening width of the open slot is smaller than the width of the free end of the tape to be clamped and is not smaller than the width of the support plate on the bottom surface of the free end of the tape to be clamped.

[0012] In some embodiments, the horizontal plate has a plurality of spacer plates spaced apart along its width direction on one side away from the vertical plate, and a space for the upper and lower clamping jaws to open and close and rotate is formed between two adjacent spacer plates.

[0013] In some embodiments, each of the partition plates is formed with a first through hole extending through its left and right end surfaces on a portion above the top surface of the horizontal plate, and each of the partition plates is formed with a second through hole extending through its left and right ends on a portion below the bottom surface of the horizontal plate, a first connecting rod is rotatably inserted into each of the first through holes and each of the upper clamping jaws is sleeved on the first connecting rod, and a second connecting rod is rotatably inserted into each of the second through holes and each of the lower clamping jaws is sleeved on the second connecting rod.

[0023] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. In the drawings, the thickness of regions and layers are exaggerated for clarity. The same reference numerals in the drawings represent the same or similar structures, and thus their detailed description will be omitted.

[0024] The described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. 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 solution of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be used. In other cases, known structures, materials or operations are not shown or described in detail to avoid blurring the various aspects of the present invention.

[0025] The following example is a tape clamping mechanism of the utility model. This example is only a part of the embodiments of the utility model, but the protection scope of the utility model is not limited to this. All other embodiments obtained by ordinary technicians in this field without creative work should be included in the protection scope of the utility model.

[0026] Please refer to Figures 1 to 5 According to an embodiment of the utility model, a tape clamping mechanism is provided, including an assembly plate 11, wherein the assembly plate 11 has a vertical plate and a horizontal plate 111 located on one side wall of the vertical plate and perpendicular to the vertical plate, that is, objectively, the assembly plate 11 is a T-shaped plate, and a plurality of upper clamps 12 and lower clamps 13 are hingedly connected to the top and bottom surfaces of the horizontal plate 111, respectively, and the first end (that is, the tape clamping end) of each upper clamp 12 has an upper clamp 121, and the first end of each lower clamp 13 has a lower clamp 131, and the upper clamp 12 and the lower clamp 13 can be driven to rotate toward or away from each other around their respective hinge points with the horizontal plate 111 to realize that the upper clamp 121 and the lower clamp 131 are in a clamping state (such as Figure 4 and Figure 5 Switching between the state shown in (shown in FIG) and the unclamped state.

[0027] In this technical solution, the upper jaw 12 and the lower jaw 13 can be driven to rotate around their respective hinge points with the horizontal plate 111. When the upper jaw 12 and the lower jaw 13 are driven to rotate in opposite directions, the upper clamp 121 and the lower clamp 131 open to form a trumpet shape. Compared with the structure in the prior art in which one clamp is fixed and the other clamp is rotated to open, a larger tape alignment space can be provided. Since the tape alignment space is widened up and down, even if the free end of the tape is bent downward or upward, the free end of the tape can be smoothly located in the tape alignment space of the tape clamping mechanism. This enables the tape clamping mechanism to clamp the free end of the tape more smoothly, thereby improving the success rate of tape clamping. Of course, it can also prevent the occurrence of tape bending caused by the upper clamp 121 or the lower clamp 131 colliding with the free end of the tape due to poor alignment.

[0028] In some embodiments, both the upper clamp 121 and the lower clamp 131 are constructed with an open groove 14, and the opening width of the open groove 14 is smaller than the width of the free end of the tape to be clamped and is not smaller than the width of the support plate (not shown in the figure) on the bottom surface of the free end of the tape to be clamped, and the aforementioned support plate is constructed at the tape lead-out channel position of the corresponding tape cutting and holding mechanism.

[0029] In this technical solution, by respectively providing the opening groove 14 on the upper clamp 121 and the lower clamp 131, when clamping the free end of the tape extending from the tape cutting and pressing mechanism, the opening groove 14 can avoid the support plate provided at the corresponding free end of the tape and realize reliable clamping of the edges on both sides of the width of the free end of the tape. It can be understood that the aforementioned support plate can prevent the free end of the tape from bending and keep it in a straight state.

[0030] In order to ensure reliable clamping of the adhesive tape, in a specific embodiment, anti-slip horizontal stripes are formed on the clamping surface of at least one of the upper clamp 121 and the lower clamp 131 .

[0031] In some embodiments, the top surface and bottom surface of the horizontal plate 111 are respectively sealed and connected with a top surface rubber film 151 and a bottom surface rubber film 152, an upper air cavity (not labeled in the figure) is formed between the top surface rubber film 151 and the top surface of the horizontal plate 111, and a lower air cavity (not labeled in the figure) is formed between the bottom surface rubber film 152 and the bottom surface of the horizontal plate 111, the second end (i.e., the driving end) of the upper clamping jaw 12 is stopped on the top surface of the top surface rubber film 151, the second end of the lower clamping jaw 13 is stopped on the bottom surface of the bottom surface rubber film 152, and an elastic member 16 ( Figure 4 and Figure 5 Only one is schematically shown in the figure, but in fact, an elastic member 16 is respectively arranged between the first ends of each pair of upper clamping jaws 12 and lower clamping jaws 13. The elastic member 16 can be a coil spring. The external pressure gas is controllably introduced into the upper air cavity and the lower air cavity, so that the clamping action of each upper clamping jaw 12 and the lower clamping jaw 13 can be controlled by the deformation protrusions of the top rubber film 151 and the bottom rubber film 152. When the pressure gas introduced into the upper air cavity and the lower air cavity is disconnected, the upper clamping jaw 12 and the lower clamping jaw 13 are opened under the elastic restoring force of the elastic member 16, thereby releasing the clamping of the tape. In the installation of this technology, the corresponding top rubber film 151 and the bottom rubber film 152 are respectively sealed and connected on the top and bottom surfaces of the horizontal plate 111, and the clamping control of each upper clamping jaw 12 and the lower clamping jaw 13 is realized by the deformation of the above-mentioned rubber film. The structure and control are simple.

[0032] In some embodiments, the upper air cavity is connected to the lower air cavity, so that the pressure of the gas in the upper air cavity is equal to that in the lower air cavity. In this case, in a specific embodiment, an air inlet cavity (not shown in the figure, for reference) is constructed in the width end region of the assembly plate 11, and the air inlet cavity is connected to the upper air cavity and / or the lower air cavity, and the air inlet cavity is connected to an air circuit connector 2, and the air circuit connector 2 is controllably connected to an external pressure source. In this technical solution, the gas pressure in the upper air cavity and the lower air cavity can be conveniently controlled by a stream of pressure air, and the structure is more compact.

[0033] In order to avoid the local pressure of the upper clamping jaw 12 being greater than the pressure of the lower clamping jaw 13, thereby causing the upper clamping jaw 12 to drive the lower clamping jaw 13 to deflect downward and form an unstable clamping position, in some embodiments, the contact surface between the second end of the upper clamping jaw 12 and the top surface adhesive film 151 is the first force-bearing surface, and the contact surface between the second end of the lower clamping jaw 13 and the bottom surface adhesive film 152 is the second force-bearing surface. The area of ​​the first force-bearing surface is smaller than the area of ​​the second force-bearing surface. It can be understood that since the gas pressure in the upper air cavity is equal to that in the lower air cavity, under the same pressure, the larger the area of ​​the force-bearing surface, the greater the corresponding driving force applied, that is, the driving force borne by the second end of the upper clamping jaw 12 is smaller than the driving force borne by the second end of the lower clamping jaw 13. According to the principle of lever, the downward clamping force applied by the upper clamp 121 will be smaller than the upward clamping force applied by the lower clamp 131. In this way, even if there is a fluctuation range in the force on the upper clamping jaw 12, the stability of the position of the lower clamping jaw 13 can be well ensured, thereby maintaining the position of the tape. Specifically, in a specific embodiment, the width of the second end of the upper jaw 12 is smaller than the width of the second end of the lower jaw 13, that is, the second end of the upper jaw 12 is a narrow surface, and the second end of the lower jaw 13 is a wide surface.

[0034] In a specific embodiment, the bottom surface and top surface of the horizontal plate 111 are respectively connected to a first positioning bar 171 and a second positioning bar (not marked in the figure), and the first positioning bar 171 and the second positioning bar respectively clamp the bottom rubber film 152 and the top rubber film 151 with the horizontal plate 111 to form a lower air cavity and an upper air cavity with reliable sealing, respectively. The first positioning bar 171 and the horizontal plate 111 clamp the bottom rubber film 152, and a horizontal positioning structure is formed between the first positioning bar 171 and the second end (i.e., the driving end) of the lower clamp 13. For details, see Figure 5As shown, the aforementioned horizontal positioning structure specifically includes an upper groove respectively constructed on the second end of the lower clamp 13 and a lower groove on the first positioning strip 171, the bottom wall of the upper groove matches the bottom wall of the lower groove, and the bottom wall of the lower groove is a horizontal plane to achieve horizontal interference between the two, so that the lower clamp 13 can clamp the tape in a horizontal state through the matching between the bottom wall of the upper groove and the bottom wall of the lower groove, thereby ensuring the flatness of the end of the tape group formed by cutting and preventing the end of the tape group from warping.

[0035] See Figure 1 As shown, in some embodiments, the side of the horizontal plate 111 away from the vertical plate has a plurality of spacer plates 112 spaced apart along its width direction, and an opening and closing rotation space (not marked in the figure) for the upper clamping jaw 12 and the lower clamping jaw 13 is formed between two adjacent spacer plates 112, which can effectively prevent the upper clamping jaw 12 and the lower clamping jaw 13 from shaking left and right during the rotation opening and closing process, thereby ensuring the stable clamping of the tape.

[0036] See Figure 5 As shown, in some embodiments, each of the partition plates 112 is formed with a first through hole penetrating the left and right end surfaces on the portion above the top surface of the horizontal plate 111, and each of the partition plates 112 is formed with a second through hole penetrating the left and right ends on the portion below the bottom surface of the horizontal plate 111, the first connecting rod 31 is rotatably inserted into each of the first through holes and each of the upper clamping jaws 12 is sleeved on the first connecting rod 31, the second connecting rod 32 is rotatably inserted into each of the second through holes and each of the lower clamping jaws 13 is sleeved on the second connecting rod 32, thereby greatly reducing the difficulty of assembly between each clamping jaw and the assembly plate 11 and simplifying the assembly structure.

[0037] 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.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
