Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a pallet feeding device. Background Technology

[0002] In related technologies, photovoltaic modules are sorted at a grading station. This station typically has a trolley where wooden pallets are placed flat. A robotic arm then places the photovoltaic modules into designated slots according to the grading rules. When wooden pallets arrive, stacking them with the flat surfaces facing upwards occupies a significant amount of overhead space, posing a safety hazard and limiting the number that can be stacked. Therefore, pallet manufacturers use a staggered arrangement, with one pallet facing upwards and another downwards, to reduce the space occupied by the pallet legs, resulting in a safer and higher-volume delivery method. However, manual pallet handling is inconvenient and inefficient. Utility Model Content

[0003] Based on this, a pallet loading device is provided to solve the problem of how to improve pallet loading efficiency.

[0004] This application provides a pallet feeding device, including:

[0005] A support frame includes a fixed base, a first support beam, and a second support beam. The first support beam and the second support beam are spaced apart from each other. Both the first support beam and the second support beam have a fixed end and a suspended end. The fixed end is connected to the fixed base, and the suspended end is suspended relative to the fixed base.

[0006] A moving mechanism, comprising a translation component and a lifting component, wherein the translation component is capable of translating along the first support beam and the second support beam, the lifting component is connected to the translation component, and the translation component is used to drive the lifting component to translate.

[0007] A flipping mechanism is connected to a moving mechanism and is used to flip a tray.

[0008] In one embodiment, the fixing base includes two columns, with the fixed end of the first support beam connected to one of the columns and the fixed end of the second support beam connected to the other column.

[0009] In one embodiment, the translation component includes a first mounting base, a first driving mechanism, and a first moving base. One end of the first mounting base is slidably connected to the first support beam, and the other end is slidably connected to the second support beam. The first driving mechanism is connected to the first mounting base and the first moving base, and is used to drive the first moving base to perform a translational movement relative to the first mounting base.

[0010] In one embodiment, the lifting assembly includes a second mounting base, a second drive mechanism, and a second motion seat. The second mounting base is connected to the first motion seat, and the second drive mechanism is connected to the second mounting base and the second motion seat. The second drive mechanism is used to drive the second motion seat to move up and down relative to the second mounting base.

[0011] In one embodiment, the number of the moving mechanisms is two, and the two moving mechanisms are arranged correspondingly along the length direction of the first support beam.

[0012] In one embodiment, there are two flipping mechanisms, which are correspondingly disposed on the second motion seats of the two moving mechanisms.

[0013] In one embodiment, the flipping mechanism includes a rotary motor, a rotating beam, and a clamping assembly. The rotary motor is mounted on the second motion seat and is used to drive the rotating beam to rotate. The clamping assembly is connected to the rotating beam and is used to clamp a tray.

[0014] In one embodiment, the rotating beam is provided with two sets of clamping assemblies, which are respectively located on both sides of the rotation center of the rotating beam.

[0015] In one embodiment, the clamping assembly includes a linear slide rail, a slider, a motor, a lead screw, a lead screw base, a mounting bracket, a rotary cylinder, a finger cylinder, and grippers. The linear slide rail is mounted on the rotating beam, the slider slides in contact with the linear slide rail, the lead screw base is mounted on the rotating beam, the motor is mounted on the rotating beam, one end of the lead screw is connected to the motor, and the other end is connected to the lead screw base. The mounting bracket is connected to the slider and can move along the linear slide rail under the drive of the lead screw. The rotary cylinder is connected to the mounting bracket, the rotating component of the rotary cylinder is connected to the finger cylinder, and the finger cylinder is connected to the grippers. The finger cylinder is used to drive the grippers to perform a clamping action.

[0016] In one embodiment, the mounting bracket is U-shaped.

[0017] The pallet loading device described above has a fixed end and a suspended end for both the first and second support beams of the support frame. The fixed end is connected to the fixed seat, and the suspended end is suspended relative to the fixed seat. This allows the space formed below the first and second support beams to facilitate the entry and exit of pallets or trolleys. Since the flipping mechanism is connected to the moving mechanism, the moving mechanism can move the flipping mechanism to the position corresponding to the pallet gripping mechanism. The flipping mechanism is used to flip the pallet. Thus, compared to the inconvenience of manually picking up pallets, the pallet loading device of this embodiment improves pallet loading efficiency by handling and flipping the pallets.

[0029] See Figure 1 As shown, one embodiment of this application provides a pallet loading device 100, which is capable of loading a pallet 200, wherein the pallet 200 may be used to load photovoltaic modules. The material of the pallet 200 may be wood or plastic, and is not limited thereto.

[0030] Combination Figure 1 and Figure 2 As shown, the pallet loading device 100 includes a support frame 10, a moving mechanism 20, and a flipping mechanism 30.

[0031] The support frame 10 includes a fixed base 11, a first support beam 12, and a second support beam 13. The first support beam 12 and the second support beam 13 are spaced apart from each other. Both the first support beam 12 and the second support beam 13 have a fixed end 10a and a suspended end 10b. The fixed end 10a is connected to the fixed base 11, and the suspended end 10b is suspended relative to the fixed base 11. In this way, the first support beam 12 and the second support beam 13 are cantilevered relative to the fixed base 11, and the space formed below the first support beam 12 and the second support beam 13 facilitates the entry and exit of the pallet 200 or the turnover cart.

[0032] It should be noted that the external dimensions of the pallet loading device 100 only need to meet the corresponding usage requirements. For example, in some embodiments, the dimensions of the pallet loading device 100 may be: length: 3000mm±200mm, width: 3000mm±200mm, height: 3000±500mm.

[0033] The mounting base 11 may include two columns 111, with the fixed end 10a of the first support beam 12 connected to one of the columns 111 and the fixed end 10a of the second support beam 13 connected to the other column 111.

[0034] In some embodiments, the fixed end 10a of the first support beam 12 may be connected to the fixed base 11 by means of welding or bolting. Correspondingly, the fixed end 10a of the second support beam 13 may be connected to the fixed base 11 by means of welding or bolting. The connection method between the first connecting beam and the fixed base 11, and the connection method between the second connecting beam and the fixed base 11 are not limited here.

[0035] The moving mechanism 20 is arranged across the first support beam 12 and the second support beam 13, and the moving mechanism 20 is capable of moving along the first support beam 12 and the second support beam 13.

[0036] Guide rails are provided on both the first support beam 12 and the second support beam 13. The moving mechanism 20 is slidably connected to the guide rails, so that the moving mechanism 20 can move smoothly along the first support beam 12 and the second support beam 13.

[0037] Combination Figure 1As shown, the moving mechanism 20 includes a translation component 21 and a lifting component 22. The translation component 21 is capable of translating along the first support beam 12 and the second support beam 13. It should be noted that the translation component 21 can translate along the first support beam 12 and the second support beam 13 under the drive of a linear motor (not shown). The lifting component 22 is connected to the translation component 21, and the translation component 21 is used to drive the lifting component 22 to translate. The lifting component 22 is capable of lifting and lowering. Understandably, the lifting and lowering direction of the lifting component 22 is perpendicular to the translation direction of the translation component 21. The translation component 21 is slidably connected to the guide rail, and therefore the direction of translation of the translation component 21 is the length direction of the guide rail.

[0038] The translation component 21 includes a first mounting base 211, a first drive mechanism, and a first motion seat.

[0039] One end of the first mounting base 211 is slidably connected to the first support beam 12, and the other end is slidably connected to the second support beam 13. In embodiments where the first support beam 12 and the second support beam 13 are provided with guide rails, both ends of the first mounting base 211 are slidably connected to the guide rails on the first support beam 12 and the second support beam 13, respectively.

[0040] The first drive mechanism is connected to the first mounting base 211 and the first moving base, and is used to drive the first moving base to perform a translational movement relative to the first mounting base 211. In this embodiment, the lifting component 22 is connected to the first moving base, so that when the first moving base moves relative to the first mounting base 211, the lifting component 22 moves with the first moving base relative to the first mounting base 211.

[0041] Since the translation direction of the translation component 21 and the lifting direction of the lifting component 22 are perpendicular to each other, and the translation component 21 moves along the guide rail, the lifting component 22 moves with the first moving seat in a direction perpendicular to the guide rail.

[0042] In the above embodiments, the lifting component 22 can not only move along the guide rail with the translation component 21, but also move in a direction perpendicular to the guide rail under the drive of the first motion seat. Subsequently, the lifting component 22 can move freely in a plane parallel to the first support beam 12 and the second support beam 13.

[0043] The lifting assembly 22 includes a second mounting base, a second drive mechanism, and a second motion seat 221. The second mounting base is connected to the first motion seat, so that the first motion seat can move relative to the first mounting base 211 along with the second mounting base. The second drive mechanism is connected to the second mounting base and the second motion seat 221, and is used to drive the second motion seat 221 to move up and down relative to the second mounting base. The direction of movement of the second motion seat 221 relative to the second mounting base is perpendicular to the first support beam 12, and the direction of movement of the second motion seat 221 relative to the second mounting base is perpendicular to the direction of movement of the first motion seat relative to the first mounting base 211. Understandably, since the first motion seat can translate relative to the first mounting base 211 under the drive of the first drive mechanism, the second motion seat 221 can move up and down relative to the second mounting base. Therefore, the horizontal movement and the vertical movement of the second motion seat 221 can be realized by using the translation assembly 21 and the lifting assembly 22.

[0044] See again Figure 1 As shown, there are two moving mechanisms 20, which are arranged correspondingly along the length of the first support beam 12.

[0045] There are two flipping mechanisms 30, which are correspondingly set on two moving mechanisms 20, so that the two moving mechanisms 20 respectively drive the two flipping mechanisms 30 to translate and lift.

[0046] The flipping mechanism 30 is connected to the second motion seat 221, so that the second motion seat 221 can carry the flipping mechanism 30 to translate and lift.

[0047] Two flipping mechanisms 30 are used to clamp onto both sides of the tray 200 and flip the tray 200.

[0048] Combination Figure 2 and Figure 3 As shown, the flipping mechanism 30 includes a rotary motor 31, a rotating beam 32, and a clamping assembly 33. The rotary motor 31 is mounted on the second motion seat 221 and is used to drive the rotating beam 32 to rotate. In this embodiment, the rotary motor 31 is connected to the rotating beam 32 to achieve the flipping of the entire rotating beam 32, thereby causing other components on the rotating beam 32 to flip together.

[0049] The clamping assembly 33 is used to clamp the pallet 200. The clamping assembly 33 is connected to the rotating beam 32, so that when the rotating beam 32 rotates, the pallet 200 clamped by the clamping assembly 33 rotates together with the rotating beam 32, thereby realizing the flipping of the pallet 200. Compared with the inconvenience of manually picking up the pallet 200, the pallet loading device 100 of this embodiment improves the pallet loading efficiency by handling and flipping the pallet 200.

[0050] In some embodiments, the rotating beam 32 is provided with two sets of clamping components 33, which are respectively located on both sides of the rotation center of the rotating beam 32. In this way, the clamping stability of the tray 200 can be improved by using two sets of clamping components 33, so that the tray 200 is not easy to fall off during the flipping process.

[0051] In some embodiments, the clamping assembly 33 includes a linear slide rail 331, a slider 332, a motor 333, a lead screw 334, a lead screw base 335, a mounting bracket 336, a rotary cylinder 337, a finger cylinder 338, and a gripper 339.

[0052] Linear slide rail 331 is mounted on rotating beam 32, and slider 332 slides in conjunction with linear slide rail 331. One end of lead screw 334 is connected to motor 333, and the other end is connected to lead screw base 335. Lead screw base 335 is mounted on rotating beam 32, and motor 333 is mounted on rotating beam 32 and used to drive lead screw 334 to rotate.

[0053] The mounting bracket 336 is connected to the slider 332 and can move along the linear slide rail 331 under the drive of the lead screw 334.

[0054] A rotary cylinder 337 is connected to a mounting bracket 336, and the rotating part of the rotary cylinder 337 is connected to a finger cylinder 338. The finger cylinder 338 is connected to a gripper 339 and is used to drive the gripper 339 to perform a gripping action.

[0055] In some embodiments, the mounting bracket 336 may be U-shaped to facilitate a stable connection with the slider 332 while accommodating the need for stable support of the rotary cylinder 337.

[0056] Combination Figure 2 and Figure 3 As shown, in some embodiments, the rotating beam 32 has grooves 321 on both sides corresponding to the rotation center. The grooves 321 are used to install the linear slide rail 331 to facilitate the miniaturization of the flipping mechanism 30. The depth of the grooves 321 can be 1000mm~1200mm, for example, the depth of the grooves 321 is 1000mm, 1100mm, 1150mm or 1200mm, and the specific depth is not limited here.

[0057] It should be noted that the gripper 339 is used to grip the flat surface of the pallet 200 and to hold the feet of the pallet 200 when it needs to be flipped. In some embodiments, the gripper 339 has a closed jaw when gripping to facilitate stable gripping of the flat surface and feet of the pallet 200.

[0058] The function of the finger cylinder 338 is to use compressed air to drive the opening and closing of the fingers in order to grasp, clamp or release objects.

[0059] The function of the rotary cylinder 337 is to convert the pressure energy of compressed air into mechanical energy, thereby realizing the rotational movement of the actuator. This allows for the adjustment of the positions of the finger cylinder 338 and the gripper 339 to facilitate the clamping of the tray 200.

[0060] It should be noted that the rotary motor 31 can be equipped with a reduction gear 34 so as to reduce the high speed of the rotary motor 31 to the required low speed through the reduction gear 34, while increasing the output torque.

[0061] Regarding the control of the pallet loading device 100, it is sufficient to adapt to the various mechanisms in the pallet loading device 100 to perform actions such as clamping, handling, or flipping.

[0062] In some implementations, the control system of the pallet loading device 100 adopts a hierarchical architecture. The top layer is the monitoring and management system, responsible for monitoring the overall operating status of the equipment, task scheduling, and data management. The middle layer is the core control unit, including a programmable logic controller (PLC) or industrial computer (IPC), which receives instructions from the upper layer and converts them into specific control signals for the lower-level actuators. The bottom layer is the drive control of various actuators, such as motor 333 drivers, solenoid valve controllers, etc.

[0063] In some embodiments, the working principle of the pallet loading device 100 for loading the pallet 200 can be as follows: after the pallet 200 receives the material, the entire pallet 200 is transported to the area below the first support beam 12 and the second support beam 13. The pallet 200 is located on one side of the fixed base 11, and the specific position can be determined according to the actual situation of equipment debugging, and is not limited here.

[0064] When photovoltaic modules require pallets 200 for tiered packaging, the trolley is pushed under the pallet loading device 100. The pallet loading device 100 is then activated, and the moving mechanism 20 moves the flipping mechanism 30 to the position of the pallet 200. The pallet 200 is clamped by the clamping component 33 of the flipping mechanism 30. Then, the rotary motor 31 drives the rotating beam 32 to rotate, thereby causing the pallet 200 clamped by the clamping component 33 to flip.

[0065] It should be noted that the rotation control of the rotary motor 31 can be configured according to the actual needs of flipping the pallet 200. For example, in some embodiments, the pallet loading device 100 is also equipped with a vision module, which is used to identify the front and back of the pallet 200. In this way, the front and back of the pallet 200 can be determined by the vision module. If it is the front, the vertical travel track will lower the flipping mechanism 30 to the center position of the pallet 200, and the lead screw 334 will rotate under the drive of the corresponding motor 333, so that each gripper 339 is distributed in a balanced manner on both sides of the short side of the pallet 200. At this time, the grippers 339 are in an upright position and remain open. After being moved by the moving mechanism 20, the four grippers 339 can maintain symmetrical gripping of the pallet 200, and then transport it to the turnover cart. If the back of the pallet 200 is facing up, the finger cylinder 338 and the gripper 339 are horizontal and remain open. Then, the four corner feet of the pallet 200 are moved, and the gripper 339 provides support to the foot feet and the tray located under the foot feet. Under the action of the rotary motor 31, the pallet 200 is flipped to complete a series of actions to face up, and then it is moved to the turnover cart.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
