[0028] Embodiment 1, as Figure 1-Figure 8 As shown, the present embodiment provides a wooden crest protection device for photovoltaic module packaging, comprising a conveying mechanism 1 and a loading mechanism.

[0029] The conveying mechanism 1 is arranged in two groups side by side and can synchronously convey the flat wooden guards. The conveying mechanism 1 includes a conveyor belt and a plurality of positioning blocks 2 equally spaced on the outer side of the conveyor belt. The positioning blocks 2 are L-shaped boss structures that can locate the placement of the wooden guards. The corners of the wooden guards can be aligned with the positioning blocks 2 to facilitate the loading mechanism to take the materials. The conveying roller mechanism 3 is used to convey the photovoltaic module packaging box. The loading mechanism can simultaneously place two wooden guards on both sides of the photovoltaic module packaging box for subsequent packaging with the strapping tape.

[0030] The loading mechanism includes a base 4, two sets of clamping and transferring mechanisms symmetrically distributed about the base 4, and a driving mechanism for driving the clamping and transferring mechanism. The clamping and transferring mechanism includes a swing arm assembly, a cross arm 13, a support rod 21 vertically arranged at the bottom of the cross arm 13, a fifth rotating shaft 22 rotatably arranged at the bottom of the support rod 21, and a clamping assembly arranged on the fifth rotating shaft 22. The swing arm assembly is a parallelogram mechanism and is connected to the fifth rotating shaft 22 by transmission. The driving mechanism is connected to the swing arm assembly by driving. The cross arm 13 is horizontally distributed and connected to the top of the swing arm assembly. The clamping and transferring mechanism has a material picking station, a transfer station, and a loading station. The conveying mechanism 1 can intermittently convey multiple wooden guards to the material picking station, and two conveying mechanisms 1 can simultaneously convey two wooden guards to the material picking station. The conveying roller mechanism 3 can intermittently convey the photovoltaic module packaging box to the loading station. When the swing arm assembly swings back and forth, the clamping assembly reciprocates through the material picking station, the transfer station and the loading station, and the wooden guardrails clamped by the clamping assembly are in a horizontal state, an inclined state and a vertical state respectively. At the material picking station, the clamping assembly can clamp the wooden guardrails placed flat on the conveying mechanism 1. At the loading station, the clamping assembly can press the wooden guardrails against the side of the photovoltaic module packaging box. Within the transfer station range between the material picking station and the loading station, the clamping assembly drives the wooden guardrails to flip 90°, and automatically adjusts the wooden guardrails from a horizontal state to a vertical state during the transfer process.

[0031] The swing arm assembly includes two parallel rotating rods 11 both rotatably arranged on the base 4 and a connecting platform 12 whose two ends are rotatably connected to the top ends of the two rotating rods 11. The connecting platform 12 is horizontally distributed, and a cross arm 13 is arranged on the connecting platform 12. The cross arm 13 always maintains a horizontal state.

[0032] The rotating rod 11 rotates within a 90° fan-shaped range, and the two extreme positions are 45° tilted at the upper left and 45° tilted at the upper right. When the rotating rod 11 rotates to the extreme position, the opposite sides of the two rotating rods 11 abut against each other, which can effectively prevent the rotating rod 11 from rotating beyond the limit value, ensuring that the rotating rod 11 rotates within the 90° range.

[0033] like Figure 5-Figure 7 As shown, the bottom end of the rotating rod 11 is rotatably connected to the base 4 through the first rotating shaft 10, and the top end of the rotating rod 11 is rotatably connected to the connecting platform 12 through the second rotating shaft 111, thereby realizing the movement of the parallelogram mechanism. The four rotating rods 11 are always parallel during movement, and the connecting platform 12 remains horizontal during movement. In order to further improve the bearing capacity of the parallelogram mechanism, multiple sets of reinforcement components can be added, and the reinforcement components include two reinforcement shafts 34 rotatably set on the four rotating rods 11 and two reinforcement platforms 35 connected to the ends of the two reinforcement shafts 34, each reinforcement platform 35 is connected to the same end of the two reinforcement shafts 34, and each reinforcement shaft 34 passes through two opposite rotating rods 11.

[0034] The top of the rotating rod 11 is connected to a connecting frame 14, and a third bevel gear 15 coaxially distributed with the second rotating shaft 111 is arranged on the connecting frame 14, and the position of the third bevel gear 15 on the connecting frame 14 is fixed, and a third rotating shaft 17 and a fourth rotating shaft 19 are rotatably arranged on the cross arm 13, and a fourth bevel gear 16 meshing with the third bevel gear 15 is coaxially arranged on the third rotating shaft 17. When the rotating rod 11 rotates, the connecting frame 14 is driven to rotate, the connecting frame 14 drives the third bevel gear 15 to rotate, and the third bevel gear 15 drives the fourth bevel gear 16 to rotate.

[0035] The third bevel gear 15 has the same specifications as the fourth bevel gear 16. The third rotating shaft 17 and the fourth rotating shaft 19, as well as the fourth rotating shaft 19 and the fifth rotating shaft 22, are connected by a belt transmission mechanism. The fourth bevel gear 16 can drive the third rotating shaft 17 to rotate. The third rotating shaft 17 drives the clamping assembly to rotate through the fourth rotating shaft 19 and the fifth rotating shaft 22, and the clamping assembly is rotated 90°. A first pulley is arranged on the third rotating shaft 17, a second pulley and a third pulley are coaxially arranged on the fourth rotating shaft 19, and a fourth pulley is arranged on the fifth rotating shaft 22. The first belt 18 is mounted on the first belt pulley and the second belt pulley, and the second belt 20 is mounted on the third belt pulley and the fourth belt pulley. The first pulley, the second pulley, the third pulley and the fourth pulley have the same specifications, so that when the rotating rod 11 rotates 90°, the fifth rotating shaft 22 also rotates 90°, and the transmission ratio is 1:1.

[0036] like Figure 8 As shown, the driving mechanism includes a base 4, a first motor 6 and a reducer 7 arranged on the base 4, a first bevel gear 8 connected to the output end of the reducer 7, and a second bevel gear 9 arranged on a first rotating shaft 10 and meshingly connected to the first bevel gear 8. The output end of the first motor 6 can be forward and reversed, and the output end of the first motor 6 is connected to the input end of the reducer 7. The first motor 6 can transmit power to the first bevel gear 8 through the reducer 7, drive the first bevel gear 8 to rotate, the first bevel gear 8 drives the second bevel gear 9 to rotate, the second bevel gear 9 drives the first rotating shaft 10 to rotate, and the first rotating shaft 10 drives the rotating rod 11 to rotate, so as to realize the movement of the parallelogram mechanism.

[0037] This embodiment uses a loading mechanism to simultaneously pick up, transfer and load two wooden guards, which is low in cost and simple in operation and maintenance. Two groups of conveying mechanisms 1 simultaneously convey the two wooden guards to their positions, and two groups of clamping assemblies clamp the two wooden guards. In the process of transferring the wooden guards from the conveying mechanism 1 to the side of the photovoltaic module packaging box on the conveying roller mechanism 3, the two wooden guards are automatically adjusted from a horizontal state to a vertical state. Both groups of clamping and transferring mechanisms flip the clamped wooden guards inward, and finally the two wooden guards are effectively pressed against the horizontal sides of the photovoltaic module packaging box, and then multiple strips of strapping are applied horizontally by a strapping machine (not shown) to fix the wooden guards on the photovoltaic module packaging box. Then, the clamping assembly is removed from here, and a new wooden guard is clamped from the conveying mechanism 1 again, and then the new wooden guard is placed on both sides of the next packaging box conveyed by the conveying roller mechanism 3, realizing continuous wooden guard loading processing with high loading efficiency.

[0038] Embodiment 2: This embodiment proposes a photovoltaic module packaging wooden rib device. Compared with embodiment 1, in this embodiment, Figure 8 As shown, a mounting cover 5 is provided on the base 4, and the mounting cover 5 shields and protects the first motor 6, the reducer 7, the first bevel gear 8 and the second bevel gear 9 on the inner side. A through hole is provided on the mounting cover 5, and a filter 40 is provided at the through hole to ventilate and dissipate heat for the operation of the first motor 6. A bracket 39 is provided inside the mounting cover 5, and a mounting shaft is rotatably provided on the bracket 39, and a sixth bevel gear 37 and a fan blade structure 38 facing the filter 40 are provided on the mounting shaft, and a fifth bevel gear 36 meshingly connected with the sixth bevel gear 37 is provided on another first rotating shaft 10. When the first rotating shaft 10 rotates, it can drive the fifth bevel gear 36 to rotate, and the fifth bevel gear 36 drives the sixth bevel gear 37 to rotate, and the sixth bevel gear 37 drives the fan blade structure 38 to rotate through the mounting shaft, and the fan blade structure 38 fans the air, accelerates the air circulation at the first motor 6, and is beneficial to the heat dissipation of the first motor 6 during operation.

[0039] Embodiment 3: This embodiment proposes a wooden rib guard device for photovoltaic module packaging. Compared with Embodiment 1, in this embodiment, Figure 7 As shown, the clamping assembly includes a rotating frame 23 arranged on the fifth rotating shaft 22, a mobile frame 24 arranged side by side with the rotating frame 23, a telescopic mechanism 25 arranged on the rotating frame 23 and driving the mobile frame 24 to move in a straight line, a slide bar 27 slidably arranged on the rotating frame 23 and the mobile frame 24, a mounting seat 26 connected to the outer end of the slide bar 27, a spring 33 connected between the mobile frame 24 and the mounting seat 26, two symmetrically distributed clamping plates 32, and a driving assembly for driving the two clamping plates 32 to move toward or away from each other. The telescopic mechanism 25 adopts an electric push rod or a cylinder. The clamping plate 32 is an L-shaped plate structure, and the outer end is inclined outward.

[0040] The fifth rotating shaft 22 can drive the rotating frame 23 to rotate, and the rotating frame 23 drives the moving frame 24 to rotate through the telescopic mechanism 25. The moving frame 24 drives the mounting seat 26 to rotate through the slide bar 27, and the mounting seat 26 drives the two clamping plates 32 to rotate through the driving assembly, thereby realizing the flipping of the wood guard between the two clamping plates 32. The spring 33 has a certain telescopic range. When clamping the wood guard, the telescopic mechanism 25 pushes the moving frame 24 to move downward, and the inner top surfaces of the two clamping plates 32 are against the top of the wood guard. The two clamping plates 32 are driven to move toward each other through the driving assembly to clamp the wood guard, and then the telescopic mechanism 25 drives the moving frame 24 to move upward to lift the wood guard upward, and the spring 33 is in a compressed state, and then the first motor 6 is operated to transfer the wood guard.

[0041] When the wood fencing is loaded onto the side of the photovoltaic module packaging box, the telescopic mechanism 25 pushes the moving frame 24 to move horizontally, and the wood fencing is stuck on the side of the packaging box. After the strapping machine horizontally straps multiple strips, the driving assembly drives the two clamping plates 32 to move apart, and the telescopic mechanism 25 contracts to pull the moving frame 24 inward, and then the first motor 6 runs, and the clamping assembly returns to the top of the conveying mechanism 1 to clamp the wood fencing again. Before the first motor 6 runs, the telescopic mechanism 25 is in a contracted state to prevent interference between the components and the packaging box and between the components and the wood fencing.

[0042] The driving assembly includes a bidirectional screw 29 rotatably arranged on the mounting seat 26, a guide rod 30 arranged on the mounting seat 26 and parallel to the bidirectional screw 29, two moving platforms 31 slidably arranged on the guide rod 30 and threadedly connected to the bidirectional screw 29, and a second motor 28 arranged on the mounting seat 26 and drivingly connected to the bidirectional screw 29. The moving platforms 31 are connected to the clamping plate 32, and the two moving platforms 31 are symmetrically distributed. The output end of the second motor 28 can be forward and reverse, and the second motor 28 drives the bidirectional screw 29 to rotate. The bidirectional screw 29 has a first threaded portion and a second threaded portion with opposite thread rotation directions. The two moving platforms 31 are threadedly connected to the first threaded portion and the second threaded portion respectively. The bidirectional screw 29 can drive the two moving platforms 31 to move toward or away from each other. The guide rod 30 plays a guiding role. The two moving platforms 31 drive the two clamping plates 32 to move toward or away from each other.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
