Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaic component production, and particularly relates to a transport mechanism for photovoltaic component pallet stacking. [Background technology]

[0002] Photovoltaic modules are placed on pallets and then placed together on the feeding station. After the transport mechanism transports all the photovoltaic modules to the production station, the pallets need to be removed from the feeding position and stacked for subsequent use. As the production line rhythm and production line output increase, multiple feeding stations will be set up, so the number of loading times becomes more frequent, resulting in the number of manual removal of pallets also becoming more frequent. Manual pallet removal is not only labor-intensive, but also the long time of manual pallet removal will lead to longer loading time, which will affect the production rhythm of the production line and lead to low production efficiency. Therefore, a transport mechanism for stacking pallets will be set up. A gantry stacking mechanism disclosed in Chinese Patent Publication No. CN 213770528 U includes a gantry main body mechanism, a horizontal transplanting device, a lifting transplanting device and a clamping device, and the clamping device includes a clamping device body, a second guide rail, a third slider, a handwheel, a cylinder and a clamp.

[0003] Although this technical solution can realize the handling and stacking of aluminum formwork, there are still two problems with this solution:

[0004] (1) The clamps in this solution are arranged vertically symmetrically, that is, the clamp device clamps the aluminum template from above and lifts the aluminum template upward through the lifting and transplanting device. During the lifting process, since the two clamps are controlled by a cylinder with a single stroke, it is easy for the aluminum template to fail to be fully clamped, resulting in the aluminum template shaking and being unstable during transportation, or even falling.

[0005] (2) The main body of the lifting and transplanting device is arranged vertically. When the aluminum templates are stacked vertically, a space needs to be reserved above the stacking area to avoid the main body of the lifting and transplanting device. Therefore, the height of the stacked aluminum templates is limited.

[0006] Therefore, in order to solve the above problems, when stacking photovoltaic module pallets, it is necessary to provide a transport mechanism for photovoltaic module pallet stacking to solve the above technical problems. [Contents of the utility model]

[0007] The main purpose of the utility model is to provide a transport mechanism for photovoltaic component pallet stacking, which has a simple and compact structure, occupies a small space, can stack the pallets to a relatively high height, and can ensure the stability of the pallets during transport.

[0008] The utility model achieves the above-mentioned purpose through the following technical solutions: a transport mechanism for stacking photovoltaic component pallets, which includes a frame, an XZ drive module fixed on the frame, a transport frame driven by the XZ drive module to move in the XZ direction and in a horizontal state, a connecting plate fixed at the end of the transport frame, a rotating drive member fixed on the connecting plate, and a bracket module driven by the rotating drive member to rotate and used to hold up the pallet; the bracket module includes a support plate fixed at the output end of the rotating drive member, a mounting frame fixed at the lower end of the support plate, and at least one pair of pallet assemblies relatively arranged on the mounting frame and used to hold up the opposite sides of the pallet; the pallet assembly includes a first drive member and a pallet driven by the first drive member to move horizontally, the two pallets are arranged back to back and anti-slip members are arranged on the pallets to prevent the pallet from sliding.

[0009] Furthermore, the XZ drive module includes a second driving member fixed on the frame, a mobile frame driven by the second driving member to move in the X direction, a first slide rail arranged on the frame, a first slider arranged on the back of the mobile frame and slidably arranged on the first slide rail, a mobile plate arranged on the front of the mobile frame, a third driving member fixed on the mobile plate and driving the mobile plate to move in the Z direction, a second slide rail arranged on the mobile frame, and a second slider arranged on the mobile plate and slidably arranged on the second slide rail; the transport frame is fixed on the mobile plate.

[0010] Furthermore, the connecting plate includes a first connecting portion fixed to the transport frame at one end and a second connecting portion for fixing the rotating drive member at the other end. The second connecting portion has a square structure at one end connected to the first connecting portion and an arc structure at the other end aligned with the outer edge of the rotating drive member.

[0011] Furthermore, a limiting column for stopping the rotation of the rotary drive member is fixed on the support plate, and after the rotary drive member is rotated to a certain position, the limiting column is restricted on the square structure of the second connecting part.

[0012] Furthermore, the support plate has a "U"-shaped structure, and the openings of the two oppositely arranged support plates are horizontally and reversely arranged.

[0013] Furthermore, the support plate includes a fixing portion at an upper end and a lifting portion disposed vertically opposite to the fixing portion, and the lifting portion is provided with the anti-slip member.

[0014] Furthermore, a third slide rail is provided on the mounting frame, a third slider disposed on the third slide rail is fixed on the first driving member, and a fourth slider disposed on the third slide rail is fixed on the fixing portion.

[0015] Furthermore, a sensor for sensing the position of the pallet is provided on the mounting frame.

[0016] Compared with the prior art, the utility model has the following beneficial effects in a transport mechanism for stacking photovoltaic module pallets: (1) the bracket module is arranged to hold the pallet horizontally, and when carrying the pallet in the XZ direction, there is no risk of the pallet shaking and falling. The pallet is in a "U"-shaped structure, and the openings of the two relatively arranged pallets are arranged horizontally in opposite directions. The two first driving members drive the pallets to extend in opposite directions, so that the two pallets extend from the inside to the outside to hold the pallet. The arrangement of the pallet assembly in this way can make the entire bracket module be above the pallet, and the size of the bracket module can be smaller than the size of the pallet, so that the size of the entire transport mechanism is smaller and the space occupied is small;

[0017] (2) The lifting part of the pallet is provided with an anti-slip part that contacts the pallet and prevents the pallet from sliding. The anti-slip part can increase the friction between the pallet and the pallet, so that the pallet can stably hold the pallet without shaking, thereby ensuring the stability of the pallet during transportation;

[0018] (3) The transport frame is fixed on the movable plate and has a horizontal structure. When stacking the pallets, the pallets can be stacked to a higher height according to the actual situation. Compared with the vertical lifting and transplanting device body, there is no need to leave an escape space above the stacking area, and the stacking height is relatively high.

[0019] Therefore, the photovoltaic module pallet stacking transport mechanism provided in the present invention has a simple and compact structure, occupies a small space, can stack the pallets to a relatively high height, and can ensure the stability of the pallets during transport.

[0034] Please refer to Figure 1-Figure 6 The present embodiment is a transport mechanism for photovoltaic module pallet stacking. The transport mechanism 100 for photovoltaic module pallet stacking includes a frame 6, an XZ drive module 1 fixed on the frame 6, a transport frame 2 that is driven by the XZ drive module 1 to move in the XZ direction and is in a horizontal state, a connecting plate 3 fixed at the end of the transport frame 2, a rotating drive member 4 fixed on the connecting plate 3, and a bracket module 5 that is driven by the rotating drive member 4 to rotate and can hold up the pallet 200.

[0035] The XZ driving module 1 includes a second driving member 11 fixed on the frame 6, a moving frame 12 driven by the second driving member 11 to move in the X direction, a first slide rail 13 arranged on the frame 6, a first slider 14 arranged on the back of the moving frame 12 and slidably arranged on the first slide rail 13, a moving plate 15 arranged on the front of the moving frame 12, a third driving member 16 fixed on the moving plate 15 and driving the moving plate 15 to move in the Z direction, a second slide rail 17 arranged on the moving frame 12, and a second slider 18 arranged on the moving plate 15 and slidably arranged on the second slide rail 17.

[0036] The transport rack 2 is fixed on the movable plate 15, and the transport rack 2 is a horizontal structure. When the pallets 200 are stacked, the pallets 200 can be stacked to a higher height according to actual conditions. Compared with the vertical lifting and transplanting device body, there is no need to leave an escape space above the stacking area, and the stacking height is relatively high.

[0037] Multiple sets of first sliders 14 and first slide rails 13 are provided between the mobile frame 12 and the frame 6, and multiple sets of second sliders 18 and second slide rails 17 are provided between the mobile plate 15 and the mobile frame 12, which can improve the stability of the XZ drive module 1 during transportation.

[0038] The connecting plate 3 includes a first connecting portion 31 fixed to the transport frame 2 at one end and a second connecting portion 32 for fixing the rotating drive member 4 at the other end. The second connecting portion 32 has a square structure at one end connected to the first connecting portion 31 and an arc structure at the other end aligned with the outer edge of the rotating drive member 4.

[0039] The bracket module 5 includes a support plate 51 fixed to the output end of the rotating drive member 4, a mounting frame 52 fixed to the lower end of the support plate 51, and at least one pair of pallet assemblies 53 relatively arranged on the lower surface of the mounting frame 52 and used to support the pallet 200 on opposite sides; the pallet assembly 53 supports the pallet 200 horizontally, and when transporting in the XZ direction, there is no risk of the pallet 200 shaking and falling.

[0040] In this embodiment, in order to improve the stability of the support, two pairs of support plate assemblies 53 are provided. In other embodiments, they can be set according to actual conditions and are not limited here.

[0041] A limiting column 511 for stopping the rotation of the rotating driving member 4 is fixed on the support plate 51. When the rotating driving member 4 drives the support frame 51 to rotate to a set angle, the limiting column 511 will be blocked by the square structure of the second connecting part 32, thereby limiting the rotation of the bracket module 5. The direction angle of the pallet 200 is precisely controlled during transportation, thereby ensuring the precise positioning of the pallet 200 during stacking and ensuring the stability of stacking.

[0042] The mounting frame 52 is provided with a sensor 521 for sensing the position of the pallet 200 .

[0043] The pallet assembly 53 includes a first driving member 531 and a pallet 532 driven by the first driving member 531 to move horizontally. The pallet 532 is in a "U"-shaped structure. The openings of the two relatively arranged pallets 532 are arranged horizontally in opposite directions. The two first driving members 531 drive the pallets 532 to extend in opposite directions, so that the two pallets 532 extend from the inside to the outside to support the pallet 200. The arrangement of the pallet assembly 53 in this way can make the entire bracket module 5 above the pallet 200, and the size of the bracket module 5 can be smaller than the size of the pallet 200, so that the size of the entire transport mechanism is smaller and the space occupied is smaller.

[0044] A third slide rail 522 is arranged on the mounting frame 52, and a third slider 5311 arranged on the third slide rail 522 is fixed on the first driving member 531. The position of the third slider 5311 on the third slide rail 522 can be adjusted according to different sizes of pallets 200 and then fixed for carrying. Pallets 200 of different sizes can be carried, and the versatility is higher.

[0045] The support plate 532 includes a fixing portion 5321 at the upper end and a lifting portion 5322 arranged opposite to the fixing portion 5321 in the upper and lower directions. A fourth sliding block 5323 slidably arranged on the third sliding rail 522 is fixed to the fixing portion 5321. The fourth sliding block 5323 is slidably arranged on the third sliding rail 522. On the one hand, it can play a guiding role. On the other hand, the support plate 532 is installed on the mounting frame 52 in the vertical direction, which can improve the stability of the support plate 532. The lifting portion 5322 is provided with an anti-slip member 5324 that contacts with the pallet 200 to prevent the pallet 200 from sliding. The anti-slip member 5324 can increase the friction between the pallet 200 and the support plate 532, so that the pallet 532 can stably support the pallet 200 without shaking, thereby maintaining the stability of the support.

[0046] The pallet 200 includes two opposite long sides 201, a plurality of cross beams 202 arranged vertically on the two opposite long sides 201, and a protective structure layer 203 provided on the surface at the intersection of the long sides 201 and the cross beams 202. The provided protective structure layer 203 can, on the one hand, prevent the photovoltaic components from rubbing against the surface of the pallet 200, and on the other hand, can serve as a contact position for carrying when the pallet 200 is carried, which is convenient for the carrying mechanism and can further reduce the size of the carrying mechanism, thereby ensuring the reliability of the carrying and saving space.

[0047] The working principle of the transport mechanism 100 for stacking the photovoltaic module pallet 200 is as follows: when the sensor 521 senses that the pallet 200 is delivered to the position, the XZ drive module 1 drives the transport frame 2 to drive the bracket module 5 to be positioned on the pallet 200, and the first drive member 531 of a pair of relatively arranged bracket assemblies 53 simultaneously drives the two pallets 532 to extend into the gap at the lower end of the pallet 200, and the XZ drive module 1 drives the transport frame 2 to drive the bracket module 5 to rise and move to the designated position. While transporting, the rotating drive member 4 can drive the bracket module 5 to rotate the pallet 200 to the set angle for positioning and stacking.

[0048] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
