Description

Technical Field

[0001] This invention relates to the field of stacker technology, and in particular to a high-efficiency stacking equipment for photovoltaic components. Background Technology

[0002] A stacker crane is a device used for automated storage and retrieval of goods. It achieves automated stacking and retrieval of goods through vertical and horizontal movement within an automated warehouse, significantly improving storage and operational efficiency. Patent CN106915586A discloses a typical stacker crane, which includes a loading platform with a telescopic arm. Extending the telescopic arm and lifting the loading platform allows for the lifting of goods, while retracting the arm completes the retrieval operation. For photovoltaic rods, due to their shape, traditional stacker cranes have poor compatibility with storage racks, resulting in low storage density, requiring large stacker cranes for retrieval, occupying significant space, and exhibiting low retrieval efficiency. Patent CN117284783A discloses a cylindrical material retrieval stacker crane, but it still suffers from complex structure and large size. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a compact and efficient stacking equipment for photovoltaic components.

[0004] Technical solution: To achieve the above objectives, the present invention provides a high-efficiency stacking equipment for photovoltaic components, which is capable of retrieving photovoltaic rods from a storage rack, wherein the photovoltaic rods are circular rods; the storage rack has a loading mechanism for placing the photovoltaic rods; the high-efficiency stacking equipment includes a movable frame and a telescopic loading mechanism, wherein the telescopic loading mechanism is capable of vertical movement relative to the movable frame.

[0005] The loading mechanism includes support bodies arranged symmetrically on the left and right.

[0006] The telescopic picking mechanism includes two rollers arranged symmetrically on the left and right, and also includes an adjustment mechanism for changing the distance between the two rollers;

[0007] The roller body includes an inner cylinder and an outer cylinder that are nested together. A push rod that acts on the outer cylinder is installed inside the inner cylinder, so that the outer cylinder can extend and retract relative to the inner cylinder, and the roller body structure is compact. The sliding direction of the outer cylinder is perpendicular to the moving direction of the inner cylinder.

[0008] During operation, the mobile frame moves horizontally under the driving force, while the telescopic picking mechanism moves vertically relative to the mobile frame, aligning itself with the target loading mechanism. Then, a push rod extends the outer cylinder, positioning it below the photovoltaic rod (with a gap between them). The adjusting mechanism then drives the two rollers closer together, causing the outer cylinder to move towards the center, squeezing the outer wall of the photovoltaic rod and pushing it away from the support. Finally, the push rod retracts the outer cylinder, completing the picking operation for the photovoltaic rod. Throughout this process, the outer cylinder and the support remain staggered and do not contact each other. The reverse process allows the photovoltaic rod to be returned to the loading mechanism.

[0009] Furthermore, the support body is an arc-shaped plate; the loading mechanism also includes two symmetrically installed baffles on the left and right sides, respectively. In this way, the support body conforms to the outer contour of the photovoltaic rod, reducing pressure, while the baffles act as a safety feature, preventing the photovoltaic rod from falling due to vibration of the storage rack. During operation, the telescopic loading mechanism moves between the support body and the baffles on the corresponding sides.

[0010] Furthermore, the adjusting mechanism includes a mechanism base, on which a guide rail is fixed; the inner cylinder of each roller is connected to a slide block, which slides in cooperation with the guide rail, and each slide block is equipped with a threaded sleeve, the two threaded sleeves being a left-handed threaded sleeve and a right-handed threaded sleeve respectively; a bidirectional screw is also rotatably mounted on the mechanism base, the bidirectional screw having a helical portion that cooperates with the two threaded sleeves respectively, the direction of rotation of the helical portion corresponding to the direction of rotation of the threaded sleeve; the bidirectional screw is driven by a first motor.

[0011] Furthermore, the outer cylinder has an adhesive layer on its outer side, and the outer cylinder can rotate relative to the inner cylinder. By providing the adhesive layer, not only can the outer cylinder prevent damage to the photovoltaic rod, but the outer cylinder can also roll relative to the photovoltaic rod when the roller moves relative to it, thus reducing resistance. Correspondingly, the outer cylinder and the push rod are connected by a slip-fitting sleeve. The slip-fitting sleeve includes a fixed part fixed to the outer cylinder and a movable part connecting the push rod. The fixed part has a movable cavity and a lead-out hole. The diameter of the movable cavity is larger than the diameter of the lead-out hole. The movable part has an insertion part placed within the movable cavity and a lead-out part extending from the lead-out hole.

[0012] Furthermore, the telescopic picking mechanism also includes an upper stop bar positioned on the vertical bisector of the two rollers; the upper stop bar is positioned higher than the rollers. After the outer cylinder picks up the photovoltaic rod and retracts, the adjusting mechanism causes the two rollers to move closer together, causing the photovoltaic rod to move upwards and abut against the upper stop bar. In this way, the rollers and the upper stop bar form a three-point clamping grip on the photovoltaic rod, effectively preventing it from falling due to accidental impact.

[0013] Furthermore, the upper stop lever can be adjusted vertically relative to the mechanism base. This allows for the adaptation to photovoltaic rods of different sizes. Specifically, the mechanism base is an inverted T-shape, having a horizontal portion and a vertical portion above the horizontal portion. A guide rail is fixed to the vertical portion, and the upper stop lever is fixed to an adjusting seat. The adjusting seat slides against the guide rail and is fixed to the mechanism base with screws. Preferably, the first motor is mounted on the back side of the vertical portion, and the first motor is vertically mounted as a whole. A transition shaft is also mounted on the back of the mechanism base. The transition shaft is connected to the bidirectional screw via a synchronous belt assembly, and the first motor and the transition shaft are connected by a bevel gear assembly. This fully utilizes the installation space and effectively improves the structural compactness.

[0014] Furthermore, guide sleeves are installed on both sides of the back of the mechanism base, a guide shaft is fixed on the movable frame, a second motor is also installed on the movable frame, a winding wheel is installed on the second motor, and a traction rope is connected between the winding wheel and the mechanism base. When the winding wheel rotates, the traction rope is wound and unwound, which realizes the lifting and lowering movement of the mechanism base.

[0015] Beneficial effects: The high-efficiency stacking equipment for photovoltaic components of the present invention has the following beneficial effects:

[0016] (1) The telescopic picking mechanism has a small and compact structure, which cleverly utilizes the characteristics of photovoltaic rods for storage and retrieval. It can quickly retrieve and return photovoltaic rods with high efficiency.

[0017] (2) Reasonable storage of photovoltaic rods can reduce the space occupied by photovoltaic rods, so that photovoltaic rods have a high storage density on the storage rack. Attached Figure Description

Detailed Implementation

[0027] The invention will now be further described with reference to the accompanying drawings.

[0028] like Figure 1 The high-efficiency stacking equipment for photovoltaic components shown can retrieve photovoltaic rods A from storage rack 1. Photovoltaic rods A are circular rods. The storage rack 1 has a placement mechanism for placing the photovoltaic rods A. The high-efficiency stacking equipment includes a movable frame 2 and a telescopic picking mechanism 3, which can move vertically relative to the movable frame 2.

[0029] like Figure 2 As shown, the loading mechanism includes symmetrically arranged support bodies 11 on the left and right sides; the support body 11 is an arc-shaped plate; the loading mechanism also includes two symmetrically installed stop bars 12 on the left and right sides, respectively, which are positioned on the left and right sides of the photovoltaic rod A. Thus, the support body 11 conforms to the outer contour of the photovoltaic rod A, reducing pressure, while the stop bars 12 act as a safety device, preventing the photovoltaic rod A from falling due to vibration of the storage rack 1. During operation, the telescopic loading mechanism 3 moves between the support body 11 and the stop bar 12 on the corresponding side.

[0030] like Figure 3-4 As shown, the telescopic picking mechanism 3 includes two rollers 31 arranged symmetrically on the left and right, and also includes an adjusting mechanism 32 for changing the distance between the two rollers 31; as Figure 5As shown, the roller body 31 includes an inner cylinder 31a and an outer cylinder 31b that are nested together. A push rod 31c that acts on the outer cylinder 31b is installed inside the inner cylinder 31a. In this way, the outer cylinder 31b can extend and retract relative to the inner cylinder 31a, and the roller body 31 has a compact structure. The sliding direction of the outer cylinder 31b is perpendicular to the moving direction of the inner cylinder 31a.

[0031] During operation, the mobile frame 2 moves horizontally under the driving force, and the telescopic picking mechanism 3 moves vertically relative to the mobile frame 2 under the driving force, so that the telescopic picking mechanism 3 is directly facing the target loading mechanism; then the push rod 31c pushes the outer cylinder 31b to extend, so that the outer cylinder 31b is placed under the photovoltaic rod A (at this time, there is a gap between the outer cylinder 31b and the photovoltaic rod A, such as...). Figure 6 (As shown), then the adjusting mechanism 32 drives the two rollers 31 to move closer to each other, causing the outer cylinder 31b to move towards the center, squeezing the outer wall of the photovoltaic rod A and pushing the photovoltaic rod A away from the support body 11 (as shown). Figure 7 (As shown), then, push rod 31c drives outer cylinder 31b to retract, enabling the picking operation of photovoltaic rod A. During the above operation, outer cylinder 31b and support body 11 are always staggered and will not come into contact with each other. By using the reverse process, photovoltaic rod A can be placed back into the loading mechanism.

[0032] With the above structure, the telescopic picking mechanism 3 is small and compact, and cleverly utilizes the characteristics of photovoltaic rod A for storage and retrieval. It can quickly retrieve and return photovoltaic rod A, with high efficiency.

[0033] Specifically, the adjusting mechanism 32 includes a mechanism base 32a, on which a guide rail 32b is fixed; the inner cylinder 31a of each roller 31 is connected to a slide block 32c, which slides in slidably with the guide rail 32b, and each slide block 32c is equipped with a threaded sleeve 32d, the two threaded sleeves 32d being a left-handed threaded sleeve and a right-handed threaded sleeve respectively; a bidirectional screw 32e is also rotatably mounted on the mechanism base 32a, the bidirectional screw 32e having a helical part that respectively engages with the two threaded sleeves 32d, the direction of rotation of the helical part corresponding to the direction of rotation of the threaded sleeves 32d; the bidirectional screw 32e is driven by a first motor 32f.

[0034] The outer cylinder 31b has an adhesive layer on its outer side, and the outer cylinder 31b can rotate relative to the inner cylinder 31a. By providing the adhesive layer, not only can the outer cylinder 31b prevent damage to the photovoltaic rod A, but it also allows the outer cylinder 31b to roll relative to the photovoltaic rod A when the roller 31 moves relative to the photovoltaic rod A, thereby reducing resistance. Correspondingly, the outer cylinder 31b and the push rod 31c are connected by a loose sleeve. The loose sleeve includes a fixed part 31d fixed to the outer cylinder 31b and a movable part 31e connected to the push rod 31c. The fixed part 31d has a movable cavity and an outlet hole. The diameter of the movable cavity is larger than the diameter of the outlet hole. The movable part 31e has an insertion part placed in the movable cavity and an outlet part led out from the outlet hole.

[0035] The telescopic picking mechanism 3 also includes an upper stop bar 33 positioned on the vertical bisector of the two rollers 31; the upper stop bar 33 is higher than the rollers 31. When the outer cylinder 31b picks up the photovoltaic rod A and retracts, the adjusting mechanism 32 causes the two rollers 31 to continue moving closer, causing the photovoltaic rod A to move upwards and abut against the upper stop bar 33. Figure 8 As shown. In this way, the roller 31 and the upper stop bar 33 form a three-point clamping of the photovoltaic rod A, effectively preventing the photovoltaic rod A from falling due to accidental impact.

[0036] The upper stop lever 33 can be adjusted vertically relative to the mechanism base 32a. This allows for the adaptation to photovoltaic rods A of different sizes. Specifically, the mechanism base 32a is an inverted T-shape, having a horizontal portion and a vertical portion above the horizontal portion. A guide rail 34 is fixed to the vertical portion. The upper stop lever 33 is fixed to an adjusting seat 35, which slides with the guide rail 34. The adjusting seat 35 can be fixed relative to the mechanism base 32a by screws 39. The mechanism base 32a has a slotted hole through which the screws 39 pass. Preferably, as shown... Figure 4 As shown, the first motor 32f is mounted on the back side of the vertical part, and the first motor 32f is mounted vertically as a whole. A transition shaft 36 is also mounted on the back of the mechanism base 32a. The transition shaft 36 is connected to the bidirectional screw 32e through a synchronous belt assembly 37, and the first motor 32f and the transition shaft 36 are connected by a bevel gear assembly 38. This makes full use of the installation space and effectively improves the structural compactness.

[0037] Guide sleeves 41 are installed on both sides of the back of the mechanism base 32a. A guide shaft 42 is fixed on the movable frame 2. A second motor 43 is also installed on the movable frame 2. A winding wheel 44 is installed on the second motor 43. A traction rope 45 is connected between the winding wheel 44 and the mechanism base 32a. When the winding wheel 44 rotates, it winds and unwinds the traction rope 45, which enables the lifting and lowering movement of the mechanism base 32a.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
