Description

Technical Field

[0001] This utility model relates to the field of photovoltaic junction box adhesive application, and in particular to a photovoltaic junction box adhesive application device. Background Technology

[0002] A photovoltaic junction box is a connecting device between a solar cell array composed of solar cell modules and a solar charging control device. Its main function is to connect and protect the solar photovoltaic modules, connect the power generated by the solar cells to external lines, and conduct the current generated by the photovoltaic modules.

[0003] During the glue application process, conventional tooling is prone to deformation, causing the junction box to shift and affecting the overall glue application trajectory. Furthermore, different tooling needs to be changed to match the different sizes of the junction boxes, which affects the smoothness of the overall production process and is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic junction box glue application device with an ingenious structure that can be applied to junction boxes of various sizes and ensure the stability of the junction box during the glue application process. It is convenient and practical.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a working platform, on which a driving cylinder is provided, and a movable support slidably mounted on the working platform under the drive of the driving cylinder. A driving motor is fixedly mounted on the movable support, and a movable plate is slidably mounted on the movable support under the drive of the driving motor. A lifting cylinder is fixedly mounted on the movable plate, and a glue-applying bracket is fixedly mounted on the telescopic end of the lifting cylinder. A hydraulic cylinder is fixedly mounted on the glue-applying bracket, and a glue gun for dispensing glue under the drive of the hydraulic cylinder is located at the output end of the hydraulic cylinder. A positioning platform is fixedly installed on the working platform, and the positioning platform has multiple parallel placement slots for placing junction boxes. Each placement slot has a positioning component for positioning the junction box. The positioning component includes multiple adjustment slots arranged on the side of the placement slot and perpendicular to the extension direction of the placement slot, adjustment slide rods slidably mounted in each adjustment slot, and pressure plates connected to each adjustment slide rod. Limiting sliders are provided on both sides of each adjustment slide rod, and limiting sliders are provided on both sides of each adjustment slot. The adjusting groove extends parallel to the limiting slide groove. Each adjusting slide rod is slidably connected to its corresponding adjusting groove through the cooperation of its limiting slider and the limiting slide groove. The bottom of the adjusting groove has multiple positioning holes evenly distributed along its extension direction. Each adjusting slide rod has a slidable positioning rod, and each adjusting slide rod has an inner cavity through which the positioning rod passes. Each inner cavity contains a tension spring, which is sleeved on its corresponding adjusting slide rod. The two ends of the tension spring act on the adjusting slide rod and the inner wall of the inner cavity, respectively. The upper end of the adjusting slide rod is located above the adjusting slide rod, and the lower end of the adjusting slide rod is inserted into the corresponding positioning hole through the continuous force of the tension spring. Each pressure plate presses against the corresponding junction box through the sliding cooperation between each adjusting slide rod and the adjusting groove. After pressing the junction box, each pressure plate is fixed by the insertion cooperation between each positioning rod and the positioning hole. The glue gun applies glue to the positioned junction box through the drive of the hydraulic cylinder, the drive motor to drive the moving bracket, the drive motor to drive the moving plate, and the lifting cylinder to drive the glue application bracket.

[0006] Furthermore, the aforementioned pressure plate includes a first plate, a second plate, and a third plate. One end of the first plate is rotatably connected to one end of the second plate, and the other end of the second plate is rotatably connected to one end of the third plate. Rotary inserts are provided on the first plate near the second plate and on the second plate near the third plate. Rotary slots corresponding to the respective rotary inserts are provided on both the second and third plates. Each rotary insert and rotary slot has a through hole, the axis of which is perpendicular to the placement groove. The through holes on the rotary inserts engage with corresponding rotary inserts. The through holes on the movable slots are coaxially arranged. Each rotating plate and its corresponding rotating slot are rotatably connected by a rotating shaft. The rotating shaft is installed in the coaxial through holes on each rotating plate and rotating slot. Each adjusting slide rod has an arc-shaped slot at the end near the pressure plate. The arc-shaped slot extends from the upper end face of the adjusting slide rod to the lower end face of the adjusting slide rod. The first plate, the second plate, and the third plate are each provided with an arc-shaped insert that matches the arc-shaped slot. The first plate, the second plate, and the third plate are connected to each adjusting slide rod through the cooperation of each arc-shaped insert and its corresponding arc-shaped slot.

[0007] Furthermore, the aforementioned placement slot has a first side slot arranged parallel to the extension direction of the placement slot. When the pressure plate is not pressing against the junction box, it is placed in the first side slot, and the outer side of the pressure plate located in the first side slot is coplanar with the side of the placement slot. One end of the placement slot is set on the positioning platform, and the other end of the placement slot extends along the moving direction of the movable bracket to protrude from the positioning platform, forming a feed port on the positioning platform for the junction box to be placed. Each feed port is provided with two opposing first baffle plates and second baffle plates, both of which are rotatably connected in the placement slot. Each placement slot has a second side slot arranged parallel to the first side slot. Both the first baffle plate and the second baffle plate are provided with internal rotating holes. The first side slot... Both the first and second side slots are equipped with positioning shafts, each positioned within a corresponding inner rotating hole. Each positioning shaft is fitted with a torsion spring, with both ends of the torsion spring acting on the inner walls of the positioning shaft and the inner rotating hole, respectively. Both the first and second baffle plates are equipped with limiting steps. When the first baffle plate is not rotating, the limiting step on the first baffle plate presses against the side wall of the first side slot. When the second baffle plate is not rotating, the limiting step on the second baffle plate presses against the side wall of the second side slot. The first and second baffle plates rotate within the placement slot through the rotational cooperation of the positioning shafts and the inner rotating holes, opening the feed inlet. After the junction box enters the placement slot, the first and second baffle plates are reset by the continuous force of each torsion spring, closing the feed inlet of the placement slot.

[0008] Furthermore, each placement slot is also provided with an inner sliding groove, which is connected to the placement slot and is set parallel to the extension direction of the placement slot. An inner sliding rod is slidably installed in each inner sliding groove, and an adjusting baffle is fixed on each inner sliding rod. A return spring is provided between each inner sliding rod and the inner sliding groove. The two ends of the return spring act on the bottom of the inner sliding rod and the inner sliding groove, respectively. Each adjusting baffle limits and presses the junction box by the sliding cooperation of the inner sliding rod and the inner sliding groove, as well as the continuous force of the return spring.

[0009] Furthermore, each positioning rod has a top ring at its upper end.

[0010] This utility model has the following positive effects: (1) This utility model places the junction box by setting multiple placement slots on the positioning platform, and sets a positioning component inside the junction box. Each pressure plate presses the side of the junction box in the corresponding placement slot through the sliding cooperation of each adjusting slide rod and the adjusting slot. At the same time, the stability of the pressure plate after pressing and the stability of pressing the junction box are ensured by the insertion cooperation of the positioning rod and the positioning hole. This effectively solves the problems of the junction box shifting during the glue application process and the poor applicability of the tooling in the prior art. The solution addresses this issue by using the positioning rod and positioning hole, along with the adjusting slide and adjusting groove, to adjust the position of the pressure plate according to different sized junction boxes. This ensures stable and secure pressure on the junction box. After pressure is applied, the glue gun, driven by a hydraulic cylinder, a drive motor driving a moving bracket, a drive motor driving a moving plate, and a lifting cylinder driving a glue application bracket, applies glue to the positioned junction box. This ensures stability during glue application while also guaranteeing efficiency and quality. It is highly adaptable, efficient, and convenient.

[0011] (2) This utility model sets the pressure plate as a connection of a first plate, a second plate and a third plate, and connects the first plate, the second plate and the third plate through the connection of a rotating insert and a rotating slot, and the rotating shaft between the rotating insert and the rotating slot. At the same time, the first plate, the second plate and the third plate and the adjusting slide rod are connected by the insertion and engagement of an arc-shaped insert and an arc-shaped slot. On the one hand, the pressure plate is set as a segmented connection, which is more suitable for junction boxes of different sizes and shapes. On the other hand, the cooperation of the arc-shaped insert and the arc-shaped slot realizes the detachable fixed connection between the pressure plate and each adjusting slide rod. At the same time, it can also realize the quick installation and disassembly of the first plate, the second plate and the third plate, so as to facilitate the replacement of the first plate, the second plate and the third plate with different shapes. This further improves the stability and adaptability of the pressure plate for junction boxes of different shapes, making it convenient and practical.

[0012] (3) By setting a first baffle plate and a second baffle plate, when the junction box enters, the junction box overcomes the torsion springs on the first baffle plate and the second baffle plate and continuously enters the placement groove. At the same time, a limiting step is set on the first baffle plate and the second baffle plate. By pressing the limiting step against the side wall of the first side groove and the limiting step against the side wall of the second side groove, the first baffle plate and the second baffle plate can only rotate within the range of the placement groove. Through the cooperation of the first baffle plate and the second baffle plate, the junction box can be effectively prevented from falling out of the placement groove during the glue application process. This further ensures that the junction box is stable during the glue application process and will not deviate, thereby further improving the glue application efficiency and glue application quality.

[0013] (4) By setting adjustment baffles in each placement slot, the adjustment baffles can press the side of the junction box by the continuous force of the reset spring and the sliding cooperation of the inner slide rod and the inner slide groove, which can further adapt to junction boxes of different lengths. In addition, the junction box can be pressed further, thereby improving the stability of the junction box in the placement slot, which is efficient and convenient.

[0014] (5) This utility model provides a top ring at the upper end of the positioning rod, which makes it convenient for operators to pull the positioning rod out of the positioning hole and adjust the adjusting slide rod, making it convenient and practical. Attached Figure Description

As each junction box is placed into the placement slot 41, it pushes open the first baffle plate 44 and the second baffle plate 45. During the opening process, the junction box overcomes the continuous force of the torsion spring 49 and pushes the first baffle plate 44 into the first side slot 42 and the second baffle plate 45 into the second side slot 43. At the same time, as the junction box enters the placement slot 41, each junction box begins to press against the adjusting baffle plate 414. After the junction box overcomes the continuous force of the reset spring 412, each junction box is fully inserted into the placement slot 41. Meanwhile, each adjusting baffle plate 414 limits and presses the junction box through the sliding cooperation of the inner slide rod 413 and the inner slide groove 411, as well as the continuous force of the reset spring 412. The first baffle plate 44 and the second baffle plate 45 are reset under the continuous force of the torsion spring 49, thereby preventing the junction boxes from falling out.

[0032] Then, the operator can rotatably connect the first plate 57, the second plate 58, and the third plate 59 through the rotating insert 513 and the rotating slot 514, and insert the rotating shaft into the corresponding through holes. Then, the first plate 57, the second plate 58, and the third plate 59 are connected to the adjusting slide rods 52 through the cooperation of the arc-shaped inserts 510 and the corresponding arc-shaped slots 521. After the connection is completed, the operator pulls out the positioning insert 55 through the corresponding positioning hole 511 through the top ring 56, and then through the sliding cooperation of the adjusting slide rods 52 and the adjusting grooves 51, The limit slides 512 and limit sliders 53 work together to press against the corresponding junction boxes. After pressing, the positioning rods 55 are reset by the continuous force of the tension spring 523 and inserted into the corresponding positioning holes 511, thereby achieving a tight and firm press against each junction box. After each junction box is positioned, the glue gun 34 applies glue to the positioned junction box by the drive of the hydraulic cylinder 33, the drive motor 21 to drive the moving bracket 2, the drive motor 21 to drive the moving plate 3, and the lifting cylinder 31 to drive the glue application bracket 32.

[0033] This invention effectively solves the problem of junction boxes shifting during the glue application process in existing technologies. By positioning and pressing the junction boxes at various locations, it effectively ensures the stability of each junction box during the glue application process. The structure is ingenious, stable, and practical.
