Description

Technical Field

[0001] This invention relates to the field of photovoltaic tracking system installation technology, specifically to a fully automated mobile photovoltaic tracking system assembly line and assembly method. Background Technology

[0002] With the development of clean energy, photovoltaic (PV) modules are finding increasingly wider applications. As the core component for converting solar energy into electricity, the installation and placement of PV modules are crucial. Since the power generation efficiency of PV is significantly affected by the angle of sunlight, using a PV tracking device to move the PV modules according to the angle of sunlight can effectively improve the photoelectric conversion efficiency.

[0003] A photovoltaic tracking system typically includes a main shaft and multiple purlins fixed to the main shaft. The purlins are perpendicular to the main shaft, and the multiple purlins form the mounting plane for the photovoltaic panels. The entire photovoltaic tracking system rotates around the main shaft to achieve tracking of the sun. To ensure connection strength and facilitate installation, a purlin pad is provided on the side of the purlin away from the main shaft, and a base support is provided on the side of the main shaft away from the purlins. The base support and the purlin pad are connected by bolt assemblies to achieve the connection between the main shaft and the purlins. To improve connection strength, diagonal braces are also connected between the base support and the purlins.

[0004] For example, the invention patent with publication number CN115765596A discloses a tilted single-axis photovoltaic panel bracket and its installation method, which adopts the above-mentioned structure. The assembly of photovoltaic tracking systems is usually carried out manually in the workshop or on-site. Due to the large size, it brings great difficulty to the assembly and the assembly efficiency is low. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a mobile photovoltaic tracking system assembly production line and assembly method.

[0006] This invention is achieved through the following technical solution: a fully automatic mobile photovoltaic tracking system assembly line is provided, including a base; a material handling machine located on both sides of the base and moving back and forth along a material handling machine guide rail; a mobile platform that moves back and forth on the base; multiple purlin positioning fixtures arranged in a front-to-back pattern are fixedly connected to the mobile platform, each purlin positioning fixture having a vertical lifting channel, a slider installed in the lifting channel, and a cylinder for driving the slider to lift and lower on the mobile platform. The upper end face of the slider has a positioning countersunk hole adapted to the bolt head of the main shaft bolt assembly. After the slider descends, the main shaft bolt assembly sinks into the lifting channel.

[0007] As an optimization, the upper end of the lifting channel has a rectangular countersunk hole adapted to the purlin pad. In this solution, the purlin pad is installed inside the purlin and on the side away from the spindle. The spindle bolt assembly passes through the purlin pad and the purlin. By setting the countersunk hole, the purlin pad is placed in the rectangular countersunk hole. When the spindle bolt assembly rises, the bolt holes on the purlin pad guide the spindle bolt assembly.

[0008] As an optimization, the purlin positioning fixture is a laterally extending rod-shaped part, and the purlin is fastened to the purlin positioning fixture. The purlin positioning fixture has a liner groove to accommodate the purlin liner. In this solution, the purlin liner is ultimately installed inside the purlin. The bolts connecting the diagonal brace and the purlin pass through the purlin liner to prevent the purlin from deforming due to tightening force. The purlin is fastened to the purlin positioning fixture, and the purlin liner is placed in the liner groove. Therefore, when the diagonal brace is connected to the purlin, the bolts can pass through the purlin liner.

[0009] As an optimization, a spindle positioning component is fixedly connected to the mobile platform to position the spindle end. In this solution, the spindle positioning component achieves the positioning of the spindle end.

[0010] As an optimization, the mobile platform is equipped with relatively movable purlin positioning clamps on both sides. The ends of the purlins are clamped by the purlin positioning clamps on both sides to achieve fixation.

[0011] As an optimization, fixed supports are provided on both sides of the base, and the purlin positioning clamp moves laterally on the fixed supports. The fixed supports serve to support the ends of the purlins.

[0012] As an optimization, a material placement rack is installed on the side of the material handling machine away from the base. In this design, the material placement rack is used to hold raw material parts.

[0013] As an optimization, the mobile platform is provided with a personnel access gap located between adjacent purlin positioning fixtures. This facilitates personnel operation within the personnel access gap.

[0014] As an optimization, it also includes a suspended traveling vehicle that travels on the suspended steel frame, with a gripping robotic arm located above the base.

[0015] A method for assembling a portable photovoltaic tracking system includes the following steps: a. The mobile platform passes through the purlin pad installation station, purlin installation station, main shaft installation station, bottom support installation station and diagonal brace installation station in sequence from front to back. The hanging traveling vehicle moves back and forth between the diagonal brace installation station, photovoltaic panel installation station and finished product placement station. b. When the mobile platform reaches the purlin pad installation position, place the spindle bolt assembly and purlin pad on the slider and position the bolt head in the positioning countersunk hole. After the slider descends, the spindle bolt assembly sinks into the lifting channel and the purlin liner is placed in the liner groove of the purlin positioning fixture. c. When the mobile platform arrives at the purlin installation position, the purlin is fastened to the purlin positioning fixture. The purlin positioning clamps on both sides move relative to each other and clamp the end of the purlin to achieve fixation. The slider rises so that the spindle bolt assembly passes through the bolt hole on the purlin. d. When the mobile platform arrives at the spindle installation position, the purlin positioning clamp clamps the end of the purlin, places the spindle on the purlin and between the two spindle bolt assemblies, and the end of the spindle rests on the spindle positioning piece to achieve axial positioning; e. When the mobile platform arrives at the base support installation position, the purlin positioning clamp clamps the end of the purlin, the base support is placed on the main shaft and the main shaft bolt assembly passes through the base support, and the main shaft bolt assembly is tightened. f. When the mobile platform arrives at the diagonal brace installation position, one end of the diagonal brace is connected to the bottom brace through the bottom brace bolt assembly, and the diagonal brace is fitted with a bottom brace liner sleeved on the bottom brace bolt assembly. The other end of the diagonal brace is connected to the purlin through the purlin bolt assembly. The purlin liner in the liner groove is located inside the purlin, and the purlin bolt assembly passes through the purlin liner. g. Photovoltaic panels are laid horizontally on the photovoltaic panel installation station. The hanging trolley picks up the semi-finished products processed at the diagonal brace installation station and places them on the photovoltaic panels to realize the installation of photovoltaic panels and purlins. h. The overhead crane picks up the finished photovoltaic panels processed at the installation station and places them at the finished product placement station.

[0016] The beneficial effects of this invention are as follows: The fully automated mobile photovoltaic tracking system assembly line and assembly method of this invention utilize automated production lines for purlins, main shafts, and base supports, which reduces manual operation, accelerates production speed, reduces production downtime, and improves production efficiency; it reduces human error and variables, improving product quality; it reduces labor costs and related training and management costs, lowering labor costs; it reduces personnel exposure to hazardous environments and repetitive labor, thereby improving workplace safety. It possesses high flexibility and adaptability, allowing for rapid adjustments and changes based on needs.

[0017] The structure, which adopts an automated production line installation method, can improve production efficiency, product quality, reduce labor costs, enhance safety, and offers high flexibility and adaptability. Furthermore, this modified structure is novel and practical. Attached Figure Description

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0020] like Figures 1-16 As shown, the fully automated mobile photovoltaic tracking system assembly line of the present invention includes a base 7, a material handling machine 13, and a mobile platform 9.

[0021] The material handling machine 13 is located on both sides of the base 7 and moves back and forth along the material handling machine guide rail 12. The material handling machine 13 grabs parts from the material placement rack 14 and places them in the required installation position. The material handling machine can move back and forth along the material handling machine guide rail 12 to place the required materials in a suitable position.

[0022] The material handling machine 13 is equipped with a material placement rack 14 on the side away from the base 7. The material placement rack 14 can store purlins, main shafts, base supports, diagonal supports, standard parts, etc., to facilitate automatic or manual feeding of the material handling machine 13.

[0023] The base 7 is provided with fixed brackets 11 on both sides. The fixed brackets 11 are fixedly installed between the base 7 and the material machine guide rail 12, and play a supporting role for the material.

[0024] The mobile platform 9 is equipped with purlin positioning clamps 1 on both sides, which move relative to each other. In this embodiment, the purlin positioning clamps 1 move laterally on the fixed bracket 11. After the purlins are loaded, they are clamped and fixed by the purlin positioning clamps 1.

[0025] The base 7 extends forward and backward and is equipped with guide rails, which allows the mobile platform 9 to move forward and backward on the base 7; the mobile platform can be raised and lowered in the vertical direction to realize the lifting operation during the installation process.

[0026] like Figure 2 As shown, multiple purlin positioning fixtures 16 arranged in a front-to-back pattern are fixed on the mobile platform 9. The spacing between the fixtures is determined according to the customer's requirements. Each purlin positioning fixture 16 is a horizontally extending rod. Purlins 2 are fastened to the purlin positioning fixtures 16. The cross-section of the purlins 2 is a U-shaped structure. The bottom of the U-shaped structure is bolted to the main shaft. Both ends of the U-shaped structure are turned outwards and the turned-out edges are bolted to the photovoltaic panels.

[0027] like Figure 6 As shown, the purlin positioning fixture 16 has a liner groove for accommodating the purlin liner 20. The purlin liner 20 is finally installed inside the purlin. The bolts connecting the diagonal brace and the purlin pass through the purlin liner. To prevent the purlin from deforming due to tightening force, the purlin is fastened to the purlin positioning fixture, and the purlin liner is placed in the liner groove. Therefore, when the diagonal brace is connected to the purlin, the bolts can pass through the purlin liner, thereby fixing the purlin liner 20 inside the purlin 2.

[0028] like Figure 10 As shown, a spindle positioning component 6 is fixedly connected to the mobile platform 9 to position the end of the spindle 8. The spindle 8 is positioned by the spindle positioning component 6 when it is placed.

[0029] The mobile platform 9 is provided with a personnel operation gap located between adjacent purlin positioning fixtures 16. This facilitates personnel operation within the personnel operation gap.

[0030] like Figure 3-5 As shown, the purlin positioning fixture 16 has a vertical lifting channel that extends into the interior of the moving platform 9. The lifting channel is equipped with a slider 17, the shape of which is the same as the cross-section of the lifting channel, thereby enabling its horizontal lifting. The mobile platform 9 is equipped with a cylinder 15 that drives the slider 17 to lift, and the cylinder 15 is fixed inside the mobile platform 9.

[0031] Since the spindle is connected to the purlin 2 via spindle bolt assemblies 18 on both sides, The upper surface of the slider 17 has a countersunk hole that matches the bolt head of the spindle bolt assembly 18. In this embodiment, the countersunk hole is hexagonal, allowing the bolt to be placed vertically within it. After the slider 17 descends, the spindle bolt assembly 18 sinks into the lifting channel, as... Figure 5 The state shown facilitates the purlin being fastened onto the purlin positioning fixture 16, while the bolt holes on the purlin are aligned with the spindle bolt assembly 18.

[0032] The upper end of the lifting channel has a rectangular countersunk hole adapted to the purlin pad 19. The purlin pad 19 is a component of the photovoltaic tracking system. Since the purlin pad 19 is installed inside the purlin and on the side away from the main shaft, the main shaft bolt assembly passes through the purlin pad and the purlin. By providing the countersunk hole, the purlin pad is placed within the rectangular countersunk hole. When the main shaft bolt assembly rises, the bolt holes on the purlin pad guide the main shaft bolt assembly. After the main shaft bolt assembly 18 rises, the bolt heads press the purlin pad 19 tightly into the purlin.

[0033] The mobile platform 9 passes sequentially from front to back through the purlin pad installation station, purlin installation station, main shaft installation station, base support installation station, and diagonal brace installation station. It also includes a suspended traveling vehicle 23 that travels along the suspended steel frame 22, with a gripping robotic arm 24 mounted on the suspended traveling vehicle 23 above the base 7. The suspended traveling vehicle 23 reciprocates between the diagonal brace installation station, the photovoltaic panel installation station, and the finished product placement station.

[0034] A method for assembling a portable photovoltaic tracking system includes the following steps: a. The mobile platform 9 passes through the purlin pad installation station, purlin installation station, main shaft installation station, bottom support installation station and diagonal brace installation station in sequence from front to back. The hanging traveling vehicle 23 moves back and forth between the diagonal brace installation station, photovoltaic panel installation station and finished product placement station.

[0035] b, such as Figure 2 As shown, when the moving platform 9 reaches the purlin pad installation position, the cylinder 15 is raised to its maximum stroke, and the spindle bolt assembly 18 and the purlin pad are placed on the slider 17 with the bolt head in the positioning countersunk hole. Specifically, the purlin pad 19 is inserted into the corresponding bolt hole of the spindle bolt assembly 18 and placed on the rectangular countersunk hole. After the slider 17 descends, the spindle bolt assembly 18 sinks into the lifting channel, and the purlin pad 19 is slightly lower than the upper surface of the purlin positioning fixture 16.

[0036] like Figure 6 As shown, a purlin liner 20 is placed in the liner groove of the purlin positioning fixture 16 to prepare for purlin installation.

[0037] c. For example Figure 7 As shown, when the moving platform 9 reaches the purlin installation station, the purlin 2 is secured to the purlin positioning fixture 16 by the material and 13. The purlin positioning clamps 1, which move relative to each other on both sides, clamp the ends of the purlin 2 to achieve fixation. The slider 17 rises, causing the spindle bolt assembly 18 to pass through the bolt holes on the purlin 2, as shown. Figure 8 The state shown.

[0038] d. For example Figure 9 As shown, when the moving platform 9 reaches the spindle installation position, the purlin positioning clamp 1 clamps the end of the purlin 2. The spindle 8 is placed on the purlin 2 and positioned between the two spindle bolt assemblies 18 using the material and 13. The spindle is perpendicular to the purlin, and the end of the spindle 8 rests against the spindle positioning component 6 to achieve axial positioning. Figure 10 As shown.

[0039] e. For example Figure 11 As shown, when the mobile platform 9 reaches the base support installation position, the purlin positioning clamp 1 clamps the end of the purlin 2, and the base support 5 is placed on the main shaft 8 through the material and 13, so that the main shaft bolt assembly 18 passes through the base support 5. The main shaft bolt assembly 18 is then tightened. Figure 12 As shown.

[0040] f. For example Figure 13 As shown, when the mobile platform 9 reaches the diagonal brace installation position, one end of the diagonal brace 4 is inserted into the base support 5, and is connected to the base support 5 through the base support bolt assembly 10. The diagonal brace 4 contains a base support bushing 21 fitted onto the base support bolt assembly 10. Figure 14 As shown.

[0041] The other end of the diagonal brace 4 is connected to the purlin 2 via the purlin bolt assembly 3. The purlin liner 20 in the liner groove is located inside the purlin 2, and the purlin bolt assembly 3 passes through the purlin liner 20. Figure 15 As shown.

[0042] g. Photovoltaic panels are laid horizontally on the photovoltaic panel installation station. The hanging trolley 23 picks up the semi-finished products processed at the diagonal brace installation station and places them on the photovoltaic panels to realize the installation of photovoltaic panels and purlins.

[0043] h. The overhead crane 23 picks up the finished products processed at the photovoltaic panel installation station and places them at the finished product placement station.
