Description
Technical Field
[0001] This invention applies to the field of automatic adhesive application and is named an automatic epoxy adhesive application device for junction boxes of solar modules. Background Technology
[0002] The junction box for solar power generation modules is a crucial component installed within these modules. It provides bypass protection for the solar cells and transmits the generated energy. A solar power system connects several modules in series and parallel via the output cables and connectors of the junction box to achieve high-power generation. This power is then supplied to consumers or connected to the grid through energy storage or inversion. Existing production equipment cannot handle the assembly and gluing of solar junction boxes, which requires multiple processing steps. The entire process is cumbersome, and traditionally, the graphite discs holding the internal parts need to be manually arranged one by one, wasting time and manpower. Existing casting machines, such as the automatic casting machine in model 202211387395.6, lack restrictions and adjustments during module placement and do not have a system to monitor the glue level. Workers must constantly monitor the glue content and add more, wasting manpower and potentially leading to insufficient glue and product quality issues.
[0003] Therefore, it is necessary to provide an automatic epoxy glue injection device for junction boxes of solar modules, which can achieve the function of automatic glue injection. Summary of the Invention

[0009] In one embodiment, a rotating shaft is provided below the placement plate, an extension plate is provided behind the rotating shaft, a push plate is provided behind the extension plate, a support bracket is fixedly installed on the front side of the placement plate, a quick-release plate is provided above the support bracket, and a placement platform is provided above the quick-release plate.
[0010] In one embodiment, a storage slot is provided above the placement platform, a push plate is slidably connected inside the storage slot, a sliding column is provided on the inner side of the push plate, a filter screen is slidably connected on the inner side of the sliding column, a second spring is welded to the rear side of the filter screen, the second spring is sleeved on the sliding column, the second spring is welded to the push plate, and a sensor head is provided on the outer side of the filter screen.
[0011] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In this invention, the electric pulley rotates, driving the conveyor block to slide back and forth on the belt, realizing the transportation of components. After the electric pulley reaches the designated position, the friction column falls on the conveyor block and fits against the belt, thereby locking the conveyor block and preventing accidental movement or deviation. Subsequently, the motor starts, which can drive the rolling wheel to rotate. The rolling wheel can drive the belt transmission, causing the conveyor block on the belt to move back and forth, realizing the fine adjustment of the position of the fixing plate. When injecting glue into the component, the drive starts, the connecting bracket first injects the tube into the storage tank, the first cylinder drives the first air rod to slide upward, and when the first air rod pushes upward, it will drive the push column upward through the connecting block, thereby making the injection tube generate suction to draw the raw glue from the front. Then it slides backward on the fourth slide rail, and stops after reaching the parallel position. The third slide rail moves horizontally on the second slide rail. The system moves to the designated glue injection point, and then the fourth slide rail slides downwards on the third slide rail to inject glue into the component. After all the work is completed, the second slide rail slides upwards on the first slide rail to prevent the bottom fixing plate from touching the glue injection component during movement. The cooperation of the first cylinder and the first air rod ensures that the injection volume is fixed and accurate, achieving the effect of automatic glue injection, which is convenient and fast. The clamping block moves downwards to hold the component, thus fixing the component on the placement plate. When the worker places the component on the placement plate, the rotating shaft will rotate along the extension plate to drive the push plate to push the improperly placed components inwards. At the same time, if the component falls off the placement plate due to sudden stop or special circumstances during transportation, the push of the filter screen and the sensor head will remind the worker to add glue material to prevent glue injection failure and insufficient glue volume, which will affect subsequent assembly and serve as a warning.

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0027] A support plate 30 is provided below the connecting bracket 29, and a first cylinder 31 is provided on the rear side of the support plate 30. Please refer to [link / reference]. Figure 1-11This invention provides a technical solution: an automatic epoxy glue injection device for a junction box of a solar module, comprising a base 1, a track 2 fixedly installed on the inner side of the base 1, a motor 3 arranged on the outer side of the track 2, a rolling wheel 5 arranged on the power shaft of the motor 3, a belt 4 wound around the outer side of the rolling wheel 5, a conveyor block 9 slidably connected to the inner side of the track 2, electric pulleys 7 connected to the two sides of the conveyor block 9, a friction column 8 slidably connected above the conveyor block 9, a fixing plate 6 arranged on the inner side of the conveyor block 9, a first slide rail 25 fixedly installed above the base 1, a second slide rail 26 slidably connected to the inner side of the first slide rail 25, a third slide rail 27 slidably connected above the second slide rail 26, a fourth slide rail 28 slidably connected to the front side of the third slide rail 27, and a connecting bracket 29 slidably connected below the fourth slide rail 28. The electric pulleys 7 rotate, driving the conveyor block 9 to slide back and forth on the belt 4, realizing the transportation of the module. 7. After reaching the designated position, the friction column 8 falls on the conveyor block 9 and abuts against the belt 4, thereby locking the conveyor block 9 to prevent accidental movement or deviation. Then, the motor 3 starts, which drives the rolling wheel 5 to rotate. The rolling wheel 5 drives the belt 4 to move the conveyor block 9 on the belt 4 back and forth, realizing the fine adjustment of the position of the fixing plate 6. When injecting glue into the component, the drive starts, and the connecting bracket 29 first uses the glue injection component to pick up the raw glue from the front, and then slides backward on the fourth slide rail 28. After reaching the parallel position, it stops. The third slide rail 27 moves horizontally on the second slide rail 26 to reach above the designated glue injection point. Finally, the fourth slide rail 28 slides downward on the third slide rail 27 to inject glue into the component. After all the work is completed, the second slide rail 26 slides upward on the first slide rail 25 to prevent the bottom fixing plate 6 from touching the glue injection component when moving, realizing the effect of automatic glue injection, which is convenient and fast.
[0028] A support plate 30 is provided below the connecting bracket 29. A first cylinder 31 is provided at the rear of the support plate 30. A first air rod 32 is slidably connected above the first cylinder 31. A connecting block 33 is fixedly installed above the first air rod 32. A push column 34 is provided below the connecting block 33. An injection tube 35 is fixedly installed at the front of the support plate 30. The push column 34 is slidably connected to the injection tube 35 and to the connecting bracket 29. When it is necessary to draw up the injection material, the injection tube 35 enters the storage tank 37. The first cylinder 31 drives the first air rod 32 to slide upward. When the first air rod 32 pushes upward, it will drive the push column 34 upward through the connecting block 33. This causes the injection tube 35 to generate suction. When the first cylinder 31 drives the first air rod 32 downward, it will similarly drive the push column 34 downward, thereby squeezing out the glue material and completing the glue injection. By utilizing the cooperation of the first cylinder 31 and the first air rod 32, the injection volume during glue injection is fixed and accurate, achieving the effect of automatic glue injection and improving production efficiency. Because this device requires two glue injection devices to cooperate with each other to dispense a certain proportion of glue, the step angle can also be controlled by a servo motor to accurately position the stroke and realize glue injection. Furthermore, the step angle of the servo motor can be used to control two different pumps to cooperate with each other to dispense a certain proportion of glue, which can also achieve the same effect.
[0029] A support base 10 is fixedly installed on the top of the base 1, and a second cylinder 11 is fixedly installed on the top of the support base 10. A second air rod 12 is slidably connected inside the second cylinder 11, and a control head 13 is provided on the outside of the second cylinder 11. When the fixed plate 6 reaches the designated position, the placement plate 14 is slidably connected to the inside of the fixed plate 6. At this time, the control head 13 controls the second air rod 12 to slide upward inside the second cylinder 11, thereby lifting the placement plate 14 upward. This indicates that the placement plate 14 is ready to proceed to the next step of glue injection, thereby ensuring sufficient space above the components during front and rear transportation, and shortening the distance between the components and the injection tube 35 during glue injection, achieving the effect of safety protection.
[0030] A placement plate 14 is slidably connected to the inner side of the fixed plate 6. A first spring 46 is welded to the top of the placement plate 14 and is welded to the inside of the fixed plate 6. A fixed chamber 15 is fixedly installed on the front side of the placement plate 14. A first connecting piece 17 is connected to the internal bearing of the fixed chamber 15. A second connecting piece 18 is connected to the internal bearing of the fixed chamber 15 and is connected to the bearing of the fixed chamber 15. A third connecting piece 44 is connected to the lower bearing of the first connecting piece 18. A threaded rod 43 is connected to the internal bearing of the fixed chamber 15. A sliding connecting rod 45 is threaded onto the outer side of the threaded rod 43. The third connecting piece 44 is connected to the bearing of the sliding connecting rod 45. A clamping block 19 is connected to the left bearing of the first connecting piece 17 and is connected to the bearing of the second connecting piece 17. A rotating mechanism 16 is provided on the outer side of the fixed chamber 15. The power shaft of the rotating mechanism 16 is fixedly connected to the threaded rod 43. When the component is on the placement plate 14, in order to prevent the component from accidentally moving, the rotating mechanism 16 rotates, which drives the threaded rod 43 to rotate. Due to the positional relationship of the first connecting piece 17, the second connecting piece 18, and the third connecting piece 44, when the threaded rod 43 rotates, the sliding connecting rod 45 can only move back and forth on the threaded rod 43. When the sliding connecting rod 45 moves backward, it drives the third connecting piece 44 to pull backward. Since the first connecting piece 17 is connected to the fixed bearing of the fixed chamber 15, and the end bearing is connected to the clamping block 19 and is limited by the second connecting piece 18, the first connecting piece 17 rotates counterclockwise, which drives the clamping block 19 to move downward, thereby clamping the component and achieving the effect of fixing the component on the placement plate 14. At the same time, the first spring 46 will spring the placement plate 14 back to its original position during the transportation process and after the second air rod 12 slides down to release the placement plate 14, achieving the effect of returning to the original position and improving safety.
[0031] A rotating shaft 22 is provided below the placement plate 14, an extension plate 21 is provided behind the rotating shaft 22, a push plate 20 is provided behind the extension plate 21, a support bracket 23 is fixedly installed on the front side of the placement plate 14, a quick-release plate 24 is provided above the support bracket 23, and a placement platform 36 is provided above the quick-release plate 24. When the worker places the component on the placement plate 14, the rotating shaft 22 will rotate along the extension plate 21 to drive the push plate 20 to push the improperly placed component inward. At the same time, during transportation, the component may fall off the placement plate 14 due to sudden stop or special circumstances, thus improving safety.
[0032] A storage slot 37 is provided above the placement platform 36. A push plate 38 is slidably connected inside the storage slot 37. A sliding column 39 is provided on the inner side of the push plate 38. A filter screen 40 is slidably connected on the inner side of the sliding column 39. A second spring 41 is welded to the rear side of the filter screen 40. The second spring 41 is sleeved on the sliding column 39 and welded to the push plate 38. A sensor head 42 is provided on the outer side of the filter screen 40. The storage slot 37 stores the glue injection material. Before glue injection, the push plate 38 will push to the left in the storage slot 37 to detect the material. The filter screen 40 can filter dust and impurities in the raw materials. When the push plate 38 is pushed to the left, the density resistance of the raw materials will cause the filter screen 40 to slide to the right within the sliding column 39. After completion, the second spring 41 will push the filter screen 40 back to its original position. However, if the filter screen 40 does not slide to the right during the push process and is pushed in the opposite direction by the second spring 41 to touch the sensor head 42, it means that the raw materials are insufficient. It is necessary to remind the workers to add glue material in time to prevent glue injection failure and insufficient glue injection, which will affect the subsequent assembly and achieve the warning function.
