Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component processing, in particular to a glue dispensing and installation device for a junction box. Background Art

[0002] During the processing of photovoltaic modules, after the high-temperature tape on the photovoltaic modules is torn off, in order to install and fix the junction box on the photovoltaic panel, it is usually necessary to use a dispensing device to apply glue on the installation position of the junction box of the photovoltaic module, and then the junction box is buckled on the photovoltaic module board. The junction box needs to be passed through the bus bar led out from the photovoltaic module board to make the bottom of the junction box bonded to the glue-coated part. After bonding, the two bus bars inserted in the junction box are bent and welded to form a current path.

[0003] Previous equipment had the glue dispensing device and the junction box installation device separately set up. Therefore, after the photovoltaic module completed the glue dispensing step, the photovoltaic module had to be transported to the junction box installation device through a conveyor line for installation. This resulted in a long connection time between the glue dispensing step and the junction box installation step, and the process was not smooth.

[0004] Therefore, how to solve the deficiencies of the above-mentioned prior art and provide a dispensing and installation device for a junction box that can improve the working rhythm has become a topic to be studied and solved by the present utility model. Summary of the invention

[0005] The utility model aims to provide a glue dispensing and installation device for a junction box.

[0016] According to a further technical solution, the dispensing module and the mounting module are both slidably disposed on a horizontal guide rail, and are respectively driven to move horizontally in the X-axis direction.

[0017] A further technical solution corresponds to a processing station setting, and the photovoltaic module is driven to move along the Y-axis direction to the processing station;

[0018] The photovoltaic module is provided with processing points, and the glue dispensing module and the installation module are driven and moved to the processing points in sequence to perform glue dispensing and installation operations.

[0019] A further technical solution is that when the camera assembly is only the first camera, the camera assembly further includes a prism, the incident end of the prism is arranged corresponding to the side of the bus bar, and the output end is arranged corresponding to the lens of the first camera. With this design, the second camera can be replaced by the prism, so that the first camera can achieve "one machine with two uses".

[0020] According to a further technical solution, the coil clamp of the wire box picking assembly has a hook-shaped portion for clamping and positioning the coil.

[0022] According to a further technical solution, first paving grooves for giving way to the straightening block are provided on both sides of the middle jaw of the straightening jaw, and second paving grooves for giving way to the horizontal stop block are provided on the sides of the left jaw and the right jaw.

[0023] According to a further technical solution, the installation module further includes a pair of expansion claws, which are arranged corresponding to the middle of the wire box clamp in the horizontal direction, and when two bus bars pass through the wire box taken by the wire box clamp, the pair of expansion claws are located between the two bus bars.

[0055] The terms used in this document generally have the ordinary meaning of each term used in this field, in the context of the case and in the specific context, unless otherwise noted. Certain terms used to describe the present invention will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the present invention.

[0056] See attached Figure 1 , 2As shown, a dispensing and installation device for a junction box includes a dispensing module 1 and an installation module 2. Both modules are slidably arranged on a horizontal guide rail 3 and are driven to move horizontally in the X-axis direction.

[0057] The device of this embodiment is set corresponding to a processing station 4, and the photovoltaic module 5 is driven to move along the Y-axis direction to the processing station 4. The photovoltaic module 5 has a processing point 6, and the dispensing module 1 and the installation module 2 are driven to move to the processing point 6 in turn to perform dispensing and installation operations.

[0058] If there are multiple processing points 6 (three in the figure), the number of dispensing modules 1 and installation modules 2 is the same as the number of processing points 6. During processing, each dispensing module 1 is simultaneously moved to each processing point 6 for dispensing, and is moved away after dispensing is completed, and then each installation module 2 is moved to each processing point 6 for installation.

[0059] It also includes a plurality of material placement trays 20 (three as shown in the figure), which are located on one side of the processing station 4 in the X-axis direction and are used to place the wired junction boxes and wireless junction boxes to be installed.

[0060] like Figure 3 , 4 As shown, the glue dispensing module 1 includes a glue dispensing component 7 and a camera component 8 , both of which are fixed on the same base 9 .

[0061] The glue dispensing assembly 7 includes a glue dispensing head 10, which is arranged downward and driven by a cylinder 11 to move in the Z-axis direction.

[0062] The camera assembly 8 includes a first camera 12 for acquiring an image of the top of the bus bar 0, and also includes a prism 13 (or a reflector), the incident end of the prism 13 is arranged corresponding to the side of the bus bar 0, and the exit end is arranged corresponding to the lens of the first camera 12. The arrangement of the prism 13 facilitates the first camera 12 to acquire the side image of the bus bar 0. In another embodiment, a second camera for acquiring the side image of the bus bar can also be arranged to replace the prism 13 (not shown in the figure), however, compared with the prism 13 scheme of this embodiment, the prism 13 is obviously more advantageous in cost control and simplifies the device composition.

[0063] like Figure 5 , 6 As shown, the installation module 2 includes a wire box picking assembly 14 and a bus bar straightening assembly 15 .

[0064] The wire box picking component 14 includes a wire box clamp 17 for picking up the wire box 16 and a coil clamp 19 for positioning the coil 18. The wire box picking component 14 is driven to move to the material placement tray 20, and the wire box part of the wireless junction box or the wired junction box is picked up by the wire box clamp 17, and the coil part of the wired junction box is positioned by the coil clamp 19 to prevent the coil 18 from shaking, thereby assisting the wire box clamp 17 to stably pick up the wire box 16 and ensure the accurate position of the wire box 16 after placement.

[0065] Preferably, the coil clamp 19 has a hook portion 21 for clamping and positioning the coil 18 .

[0066] like Figures 7-9 As shown, the busbar straightening assembly 15 includes a straightening clamp 22, and also includes a driving mechanism for driving the straightening clamp 22 to move in the Z-axis direction and at least to move horizontally in the X-axis. The driving mechanism for driving the straightening clamp 22 to move in the Z-axis direction is a first cylinder 23, and the driving mechanism for driving the straightening clamp 22 to move horizontally in the X-axis is a second cylinder 24.

[0067] The straightening jaw 22 includes a left and right jaw arranged in pairs and a middle jaw 27 located between the left and right jaws, and also includes a driving mechanism for driving the left and right jaws to open and close and move horizontally along the X axis. The driving mechanism for driving the left and right jaws to move horizontally along the X axis is a third cylinder 28, and the driving mechanism for driving the left and right jaws to open and close is a fourth cylinder 29.

[0068] The inner sides of the left and right clamps are both provided with a straightening block 30 protruding toward the middle clamp 27, and the two sides of the middle clamp 27 are respectively provided with a horizontal stopper 31 protruding toward the left clamp 25 and the right clamp 26, and the two straightening blocks 30 are both located at the front end of the horizontal stopper 31. When the left and right clamps are closed, the left and right clamps are both close to the middle clamp 27, forming a straightening position 32 of a bus bar on each side, and each straightening position 32 is defined by the side of the middle clamp 27, the inner side of the left clamp 25 or the right clamp 26, the front end of the horizontal stopper 31 and the rear end of the straightening block 30.

[0069] Preferably, both sides of the middle clamping jaw 27 are provided with first making way grooves 33 for making way for the straightening block 30 , and the sides of the left clamping jaw 25 and the right clamping jaw 26 are provided with second making way grooves 34 for making way for the horizontal stopper 31 .

[0070] Preferably, the installation module 2 further includes a pair of expansion claws 35, which are arranged in the middle of the horizontal direction of the wire box clamping claws 17, and when the two bus bars 0 are passed through the wire box 16 taken by the wire box clamping claws 17, the pair of expansion claws 35 are located between the two bus bars 0. The two bus bars 0 are bent at the same time by opening the pair of expansion claws 35. The previous expansion device is an independent module, so when the wire box is passed through the bus bar, the wire box taking component 14 needs to be moved away, and then the expansion device needs to be moved in to perform the expansion action. In this embodiment, the expansion claws 35 are integrated with the wire box taking component 14, which not only saves time cost but also optimizes the work rhythm.

[0071] The working principle of the utility model is described as follows:

[0072] First, the photovoltaic component 5 is transported to the processing station 4 by the photovoltaic component transportation device. At this time, the glue dispensing component 7 in the glue dispensing module 1 is at the bus bar 0 position on the photovoltaic component 5 (that is, the processing point 6, which is the installation position of the junction box on the photovoltaic component 5). At this time, the wire box picking component 14 of the installation module 2 picks up the wire box 16 on the placing tray 20.

[0073] Then, the glue dispensing component 7 in the glue dispensing module 1 performs the glue application action. After the glue application action is completed, the glue dispensing module 1 moves backwards and moves the camera component 8 to the processing point 6 of the photovoltaic module 5. The first camera 12 of the camera component 8 takes pictures to check whether the shape and height of the bus bar 0 in the processing point 6 meet the installation requirements of the junction box. If it does not meet the installation requirements, the photovoltaic module 5 needs to be moved away, so that the next photovoltaic module 5 can be transported in, and then the previous work can be performed; if it meets the installation requirements, the glue dispensing module 1 moves as a whole to avoid, and then the wire box picking component 14 in the installation module 2 holding the wire box 16 moves to the processing point 6 of the photovoltaic module 5.

[0074] At this time, the first cylinder 23 drives the busbar straightening assembly 15 to move downward, and the straightening jaw 22 on the busbar straightening assembly 15 is just 4 to 5 mm above the root of the busbar 0. Then the second cylinder 24 drives the straightening jaw 22 to move toward the direction of the wire box taking assembly 14. With the movement of the straightening jaw 22, the two busbars 0 are just inserted into the straightening jaw 22 until the front side of the horizontal stopper 31 abuts against the rear side of the busbar 0, and the second cylinder 24 stops moving (see Fig.10 , 11 Then, the fourth cylinder 29 drives the left clamping jaw 25 and the right clamping jaw 26 to close to the position close to the middle clamping jaw 27 (see Fig.12 , 13 Then, the third cylinder 28 drives the left clamping jaw 25 and the right clamping jaw 26 to move simultaneously in a direction away from the wire box taking assembly 14 (see Fig.14 ,15 In this process, the rear end of the straightening block 30, the front end of the horizontal stopper 31, the inner side surfaces of the left clamp 25 and the right clamp 26, and the left and right side surfaces of the middle clamp 27 together form the straightening position 32 to straighten the busbar 0 tilted outward, and make the distance between the two busbars 0 in the straightening clamp 22 meet the installation requirements of the junction box.

[0075] The front side surface of the straightening block 30 and both sides of the front end of the middle clamping jaw 27 are provided with guiding inclined surfaces 36 for guiding the bus bar 0.

[0076] Then, the wire box picking assembly 14 moves downward, and the two bus bars 0 are inserted into the junction box. Then, the straightening clamp 22 is driven away from the wire box picking assembly 14, and the wire box picking assembly 14 is driven to continue to move downward, so that the upper end of the bus bar 0 protrudes from the surface of the junction box. Figures 16 to 19 As shown, the expansion claws 35 in the wire box picking assembly 14 are driven to open to both sides, so that the bus bar 0 is bent to both sides. Finally, the wire box picking assembly 14 is driven to move downward, so that the expansion claws 35 press down the bent bus bar 0, so that the bus bar 0 contacts the welding part of the junction box, which is convenient for the subsequent welding process.

[0077] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
