Description

Technical Field

[0001] The present invention belongs to the technical field of automatic production line equipment, and in particular relates to a pallet side support assembly, a pallet and a method for using the pallet. Background Art

[0002] AGV pallets are becoming more and more popular in the field of battery workpiece loading and handling. The backpack AGV is a vehicle that places pallets, material racks, material boxes and other goods on the AGV body for transportation, thereby saving development costs and labor costs, and greatly saving the development time of new energy products.

[0003] The AGV tray side support mechanism disclosed in the prior art generally includes a mechanism body, a fixed seat, a slider, a spring, and an abutment structure. The slider slides in the mechanism body and is elastically supported by the spring to buffer the battery workpiece. When the tray is tilted, the side abutment body and the bottom abutment body will provide elastic support force to the workpiece to ensure that the workpiece will not generate a breaking force on the fixing pin. However, the following problems often occur during actual use:

[0004] After the battery workpiece is placed on the support mechanism, the elastic support mechanism cannot move horizontally, causing the battery workpiece to produce intense friction with the slider of the elastic support mechanism during the falling process, which is not only easy to wear the slider, but also easy to scratch the surface of the battery workpiece. In addition, because the side support mechanism of the tray cannot clamp the battery workpiece from the side, when the battery workpiece is tilted and transported, the battery workpiece will shake due to vibration. When it collides with the slider for a long time, it will also wear the slider and the surface of the battery workpiece, affecting the service life of the slider. In serious cases, there is even a risk of the battery workpiece falling off. Summary of the invention

[0005] In view of the technical problems of wear of sliding blocks and battery workpiece surfaces existing in the prior art, the present invention provides a tray side support assembly, a tray and a tray use method to solve the above problems.

[0006] To solve the above problems, the present invention adopts the following technical solutions:

[0007] The present invention provides a pallet side support assembly, including a pallet side support assembly, including a support body fixed on the pallet, the support body having a slide groove, an elastic support mechanism installed in the slide groove, the track of the slide groove extends along a first direction, and the first direction has an inclined angle with the vertical direction, so that when the elastic support mechanism slides along the track of the slide groove, it can generate displacement in the vertical direction and the horizontal direction at the same time.

[0008] Furthermore, the elastic support mechanism includes a slider, which is located in the slide groove; the slider has a sliding part adapted to the track of the slide groove, and when the sliding part slides along the slide groove, it can generate displacement in the vertical and horizontal directions at the same time.

[0009] The elastic support mechanism is used to slow down the descending speed of the battery workpiece during the loading process of the battery workpiece, and reduce the impact force it receives during the loading process. When the battery workpiece is placed on the slider, it presses the slider to slide downward along the slide track, and the elastic member in the elastic support mechanism provides a rebound support force for the slider, reducing the descending speed of the slider and the battery workpiece. In particular, the track of the slide in the present invention extends along a first direction and there is an inclined angle between the first direction and the vertical direction, so that when the slider slides along the slide (first direction), displacements in two directions occur simultaneously. One is a vertical displacement, which acts as a buffer in conjunction with the elastic member, and the other is a horizontal displacement, so that when the slider is squeezed by the side of the battery workpiece, it can move away from the side of the battery workpiece, thereby leaving a gap to accommodate the battery workpiece falling into the elastic support mechanism, while reducing the friction between the slider and the battery workpiece and reducing the wear rate of the slider. When the battery workpiece falls into place (falls onto the elastic support mechanism), the elastic member supports the slider to move upward along the first direction, so that the slider can be displaced horizontally, so that it can press against the side of the battery workpiece from the side, clamp the battery workpiece, prevent the battery workpiece from shaking between the sliders, and avoid bumps between the battery workpiece and the slider.

[0010] Furthermore, the inclination angle ɑ of the first direction to the vertical direction is ≤20°. The inclination angle is used to control the horizontal displacement distance of the slider. When the inclination angle is controlled within this range, the horizontal displacement of the slider will not be too large to cause a gap between the slider and the battery workpiece, nor will it be too small to fail to clamp the battery workpiece.

[0011] Furthermore, the sliding portion includes a horizontal bottom plate and side plates parallel to the bottom wall of the slide groove, and the bottom plate and the side plates are connected end to end.

[0012] Furthermore, the slide block includes a guide component for guiding the battery workpiece to fall into the slide block, and the guide component is fixed to the side plate. After the battery workpiece contacts the guide component, the guide component guides the battery workpiece to be aligned, thereby solving the problem that the battery workpiece is difficult to align during the loading process.

[0013] Furthermore, the elastic supporting mechanism includes an elastic member located at the bottom of the sliding block.

[0014] Furthermore, the elastic member is a spring, one end of which is inserted into the protrusion at the bottom of the slider, and the other end is located in the hole at the bottom of the slide. The protrusion at the bottom of the slider can just enter the end of the spring to prevent the spring from falling out of the slide during compression.

[0015] Furthermore, the support body includes a base, and the base is detachably connected to the tray. The detachable connection facilitates the replacement of the tray side support assembly, and when the tray side support assembly is damaged, it can be replaced with a new one for continued use.

[0016] Furthermore, the support body includes a workbench fixedly connected to the base, and the workbench has an L-shaped opening for accommodating the edge of the battery workpiece. The L-shaped opening is adapted to the shape of the bottom of the battery workpiece, so that the battery workpiece can be more stably placed on the support body.

[0017] Furthermore, a sealing plate is connected to the L-shaped opening, and the sealing plate is used to limit the moving distance of the slider. When the slider moves upward to a certain distance along the first direction, the slider body will contact the sealing plate, so that the slider cannot continue to move upward. At the same time, it can also prevent the slider from detaching from the slide groove during the sliding process.

[0018] Furthermore, the sealing plate is detachably connected to a cushion block. After the battery workpiece is placed, it falls on the cushion block. Since the cushion block is directly fixed on the supporting body, most of the weight of the battery workpiece is directly borne by the supporting body, which reduces the pressure on the slider caused by the battery workpiece during transportation and increases the service life of the slider.

[0019] A pallet comprises a chassis, wherein the chassis is composed of four cross beams connected end to end, and a plurality of pallet side support assemblies are mounted on the cross beams.

[0020] A method for using the pallet, comprising:

[0021] S1: Use a lifting device to lift the battery workpiece and slowly move it to just above the tray;

[0022] S2: Control the lifting equipment to lower the height of the battery workpiece so that the bottom of the battery workpiece falls onto a plurality of tray side support assemblies on the tray during the falling process;

[0023] S3: the battery workpiece is automatically aligned on the tray side support assembly, and during the alignment process, the elastic support mechanism supports the bottom of the battery workpiece so that it slowly falls onto the pad of the tray side support assembly;

[0024] S4: The slider of the tray side support assembly performs a reset action under the support of its elastic member and presses against the side of the battery workpiece to clamp the battery workpiece to prevent it from loosening.

[0025] During the use of the above-mentioned tray, the battery workpiece can be slowly placed in place without causing impact to the battery workpiece. During the loading process of the battery workpiece, the slider moves in the opposite direction of the battery workpiece to reduce the friction between the slider and the battery workpiece, and avoid mutual damage between the slider and the battery workpiece due to severe friction. After the battery workpiece is placed in place, the slider can clamp the battery workpiece under the push of the elastic member to prevent it from shaking, and avoid bumps and scratches on the battery workpiece during operation due to shaking between the slider and the battery workpiece.

[0039] The following detailed description of exemplary embodiments of the present invention refers to the accompanying drawings, which form a part of the description, and in which exemplary embodiments of the present invention that can be implemented are shown as examples. Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments can be implemented and various changes can be made to the present invention without departing from the spirit and scope of the present invention. The following more detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but is only for the purpose of illustrating and not limiting the description of the characteristics and features of the present invention, so as to propose the best mode for performing the present invention and to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

[0040] In order to solve the above problems, the following is described in conjunction with the accompanying drawings:

[0041] Note: The horizontal direction and vertical direction described in the present invention are as follows Figure 6 As shown, it is set relative to the tray side support assembly.

[0042] Embodiment 1:

[0043] The present invention relates to a pallet side support assembly 1. The pallet 2 is used to transport battery workpieces 3. The pallet 2 is composed of two long beams and two short beams, and the four beams are connected end to end. The middle part of the pallet 2 is hollowed out. Each pallet 2 includes a plurality of pallet side support assemblies 1, and the plurality of pallet side support assemblies 1 are usually symmetrically installed on the long beams or short beams of the pallet 2. When the pallet 2 is needed to transport the battery workpiece 3, the battery workpiece 3 is loaded between the plurality of pallet side support assemblies 1 on the pallet 2, and the plurality of pallet side support assemblies 1 are jointly supported on the bottom 31 of the battery workpiece for transportation.

[0044] like Figure 1-2 As shown, the tray side support assembly 1 includes a support body 11, which is composed of two parts, namely a base 111 and a workbench 112. The base 111 is a rectangular metal block, and two rows of parallel through holes 1111 are drilled near the sides of the base 111. The base 111 is detachably fixed to the tray 2 by passing screws 1112 through the through holes 1111.

[0045] The base 111 is integrally connected to a workbench 112 in the middle, which is used to install components that support the battery workpiece 3. The end of the workbench 112 connected to the base 111 is the lower end of the workbench 112, and the end away from the base 111 is the upper end of the workbench 112. The upper end of the workbench 112, close to the hollow side of the tray 2, is an L-shaped opening 1121, and the L-shaped opening 1121 is just adapted to the shape of the bottom 31 of the battery workpiece. When the battery workpiece 3 is loaded onto the tray 2, the bottom 31 of the battery workpiece is supported in the L-shaped opening 1121. The workbench 112 has a slide 1122 extending along a first direction in the middle of one side of the L-shaped opening 1121. The track of the slide 1122 extends from top to bottom (from the upper end of the workbench 112 to the lower end of the workbench 112). An elastic support mechanism 4 is installed in the slide 1122, which is used to reduce the impact force on the battery workpiece 3 during the loading process of the battery workpiece 3.

[0046] like Figure 3 As shown, the elastic supporting mechanism 4 includes a sliding block 41 and an elastic member 42 .

[0047] like Figure 4 As shown, the slider 41 includes a sliding portion 411 located in the slide slot 1122, and the sliding portion 411 drives the slider 41 to slide along the track of the slide slot 1122. The sliding portion 411 is divided into a horizontal bottom plate 4111 and a side plate 4112 parallel to the bottom wall of the slide slot 1122. The side plate 4112 and the bottom plate 4111 are fixed together end to end. When the side plate 4112 is subjected to pressure, it will slide along the track of the slide slot 1122 close to the bottom wall of the slide slot 1122.

[0048] like Figure 5As shown, the slider 41 includes a guide component 412, which is detachably connected to the side plate 4112, specifically, it can be connected by bolts or pins. The guide component 412 follows the sliding part 411 to move along the track direction of the slide groove 1122. The guide component 412 includes an inclined contact surface 4121 facing one side of the battery workpiece 3, and the angle β (inclination angle) between the inclined contact surface 4121 and the vertical direction does not exceed 30°, preferably 20°. If the angle β is too large, the bottom 31 of the battery workpiece will be subject to large friction and it will be difficult to slide down along the inclined contact surface 4121. During the falling process of the battery workpiece 3, its bottom first falls on the inclined contact surface 4121, and the inclined contact surface 4121 has a guiding ability, so that the battery workpiece 3 automatically slides along the direction of the inclined contact surface 4121. After the bottom 31 of the battery workpiece slides along the inclined contact surface 4121, the workpiece automatically completes the straightening action. At this time, the four sides of the battery workpiece 3 are parallel to the four beams of the tray 2, and the battery workpiece 3 is located in the middle of the tray 2. The guide component 412 can automatically adjust the falling direction of the battery workpiece 3 during the loading process, and realize automatic alignment with the tray 2, without manual adjustment for a long time, saving time and effort. The guide component 412 is a contact component with the battery workpiece 3, and it has insulation and wear resistance. Its material is high molecular polytetrafluoroethylene. The guide component 412 is in contact with the battery workpiece 3, so the insulated guide component 412 can effectively prevent the risk of leakage conduction of the battery workpiece 3.

[0049] like Figure 6 As shown, the elastic member 42 is located in the slide groove 1122, and a spring is usually used. One end of the elastic member 42 is inserted into the protrusion at the bottom of the bottom plate 4111, and the other end is supported at the bottom of the slide groove 1122. There is a hole at the bottom of the slide groove 1122, and the lower end of the spring is located in the hole. This structure can prevent the spring from falling out of the slide groove 1122 during the compression process. When the slider 41 moves downward along the slide groove 1122, an elastic supporting force F1 is provided to the slider 41, slowing down the movement speed of the slider 41, thereby reducing the impact force on the battery workpiece 3 connected to the slider 41.

[0050] The entire elastic support mechanism 4 is used to provide elastic support to the battery workpiece 3 during the loading process, so as to prevent the battery workpiece 3 from being damaged by a large impact force.

[0051] Embodiment 2:

[0052] Sealing plate 5 and spacer block 6:

[0053] like Figure 1As shown, the sealing plate 5 is fixed in the L-shaped opening 1121 of the supporting body 11. The sealing plate 5 is an L-shaped plate adapted to the L-shaped opening 1121 of the supporting body 11, and its vertical part and horizontal part are detachably fixed to the L-shaped opening 1121 of the supporting body 11 by bolts. The horizontal part of the sealing plate 5 is provided with a notch at the slide slot opening 1123, and the slider 41 passes through the notch, so that the horizontal part does not affect the sliding of the slider 41 in the slide slot 1122. However, the side wall of the notch has a limiting effect on the slider 41, limiting the moving distance of the slider 41 in the first direction and the horizontal direction, and preventing the slider 41 from jumping out of the slide slot 1122 during the sliding process.

[0054] like Figure 1 As shown, a pad 6 is detachably connected to the top of the sealing plate 5, and the pad 6 is made of insulating material and has insulating properties. The pad 6 is used to support the bottom 31 of the battery workpiece. When the battery workpiece 3 slides off the guide component 412, it slowly falls on the pad 6, and the weight of the battery workpiece 3 is supported by the pad 6. Since the pad 6 is connected to the supporting body 11, the weight of the entire battery workpiece 3 will be borne by the tray 2. Since the weight of the battery workpiece 3 is not supported by the slider 41, the service life of the slider 41 is increased. At the same time, the elastic supporting force F1 under the slider 41 will not act entirely on the battery workpiece 3, and the battery workpiece 3 will not be overturned and fall off during the flipping process.

[0055] Example 3

[0056] like Figure 6As shown, the angle of inclination between the first direction and the vertical direction is ɑ≤20°, specifically, it is deflected counterclockwise along the vertical direction. The inclination angle ɑ is preferably 5-10°, and the inclination angle is used to control the horizontal displacement distance of the slider 41. When the inclination angle is controlled at an inclination angle ɑ≤20°, preferably 5-10°, the horizontal displacement of the slider 41 will not be too large to cause a gap between the slider 41 and the battery workpiece 3, nor will it be too small to cause the battery workpiece 3 to be clamped. In the sliding part of the corresponding slider 41, the side plate 4112 and the bottom of the track of the chute 1122 are parallel. When the side plate 4112 slides downward along the track of the chute 1122, the slider 41 will produce a horizontal displacement in the direction away from the chute opening 1123. When the battery workpiece 3 falls on the slider 41, the slider 41 is pressed to slide downward along the track of the chute 1122, and the elastic member 42 under the slider 41 provides a rebound support force for the slider 41, reducing the descending speed of the slider 41 and the battery workpiece 3. On the other hand, during the descent of the slider 41, it moves in the horizontal direction away from the chute opening 1123 (away from the battery workpiece 3), reducing the friction between the slider 41 and the battery workpiece 3, and reducing the wear between the slider 41 and the battery workpiece 3. After the battery workpiece 3 is in place, the slider 41 is reset (moved upward) under the elastic support force F1 of the elastic member 42. Since the track of the chute 1122 has an inclined angle ɑ, the slider 41 will produce a horizontal movement facing the side of the battery block, so that the side of the slider 41 can press against the side 32 of the battery workpiece and apply a lateral force F2 to the side 32 of the battery workpiece, thereby clamping the battery workpiece 3. Avoid the battery workpiece 3 from shaking between the sliders 41, and avoid bumps between the battery workpiece 3 and the slider 41.

[0057] A method for loading a battery workpiece 3 using a tray 2:

[0058] S1: Use a lifting device to lift the battery workpiece 3 and slowly move the battery workpiece 3 to just above the tray 2;

[0059] S2: Control the lifting equipment to lower the height of the battery workpiece 3. During the falling process, the bottom of the battery workpiece 3 falls onto the inclined contact surfaces 4121 of the plurality of elastic support mechanisms 4 on the tray 2;

[0060] S3: The battery workpiece 3 is aligned under the guidance of the inclined contact surface 4121, and during the alignment process, it slowly falls onto the cushion block 6. The specific alignment process is that the bottom of the battery workpiece 3 slides along the inclined contact surfaces 4121 under the action of gravity, and the horizontal position of the bottom 31 of the battery workpiece is adjusted (since the multiple inclined contact surfaces 4121 on the same side are located in the same plane, the bottom of the battery workpiece 3 on the same side will automatically align and adjust along the inclined contact surface 4121). While the bottom 31 of the battery workpiece slides and is aligned along the inclined contact surface 4121, the battery workpiece 3 applies a vertical downward force to the slider 41 to drive the slider 41 to slide downward along the slide. During the downward sliding of the slider 41, the elastic member 42 is deformed to provide an elastic support force F1 to the slider 41 to offset the gravity of the battery workpiece 3 itself and reduce the impact force received by the battery workpiece 3 during its rapid fall.

[0061] S4: The bottom 31 of the battery workpiece is placed on the cushion block 6 on the sealing plate 5 , and the cushion block 6 supports the weight of the battery workpiece 3 .

[0062] S5: The slider 41 is reset under the support of the elastic member 42 , pressed against the side surface 32 of the battery workpiece, and clamped the battery workpiece 3 .

[0063] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
