Description

Technical Field

[0001] This utility model relates to the field of mechanical structure assembly technology, and in particular to a transport frame and assembly line. Background Technology

[0002] During assembly, various components need to be installed inside the cabinet. Since the distribution box needs to be assembled at several workstations, it must be transported between these workstations. A transport rack is typically used for this transfer. In existing technology, the lifting mechanism of the transport rack generally uses a chain drive structure. This involves connecting the two ends of a chain to the upper and lower ends of the lifting platform, and the lifting drive component drives the chain to rotate, thus raising and lowering the platform. In this structure, the chain needs to bear a significant load, posing a risk of breakage when the chain pulls the platform upwards, potentially causing a safety accident. Utility Model Content

[0016] When the opposite ends of the push-pull sliding plates on both of the lifting frames extend out of the slide groove, the push-pull sliding plates of the two lifting frames are used to support the conveying component.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1-2 As shown, this utility model embodiment provides a transport frame 1, which includes a frame 11, a translation mechanism 12 and a lifting mechanism 13.

[0043] The translation mechanism 12 includes a translation drive 121, a translation frame 122, and a translation transmission assembly. The translation frame 122 is movably mounted on the frame 11 along a first horizontal direction. The translation drive 121 is mounted on the translation frame 122 and drives the translation frame 122 to translate along the first horizontal direction through the translation transmission assembly.

[0044] The lifting mechanism 13 includes a lifting drive component 131, a fixed frame 132, a lifting frame 133, and a lifting drive assembly. The fixed frame 132 is connected to the translation frame 122. The lifting frame 133 is used to carry the conveying component 100 (which can be selected as a power distribution box in this embodiment) to be conveyed. The lifting frame 133 and the fixed frame 132 are movably connected in the vertical direction (a guide rail slider structure can be selected, in which the guide rail is set in one of the fixed frame 132 and the lifting frame 133, and the slider of the guide rail slider structure is set in the other of the fixed frame 132 and the lifting frame 133). The lifting transmission assembly includes a steering box 134, a lifting screw 135, a lifting chain 136, a lifting drive sprocket 137, and a lifting driven sprocket 138. The steering box 134 is set on the fixed frame 132. The steering box 134 includes a vertically distributed input shaft and an output shaft. When the input shaft rotates, it can drive... The output shaft rotates simultaneously (the steering box 134 is existing technology, and its working principle will not be described). The lifting screw 135 is screwed to the lifting frame 133, and the upper end of the lifting screw 135 is connected to the output shaft of the steering box 134, so that the output shaft drives the lifting screw 135 to rotate. The lifting drive sprocket 137 is connected to the output end of the lifting drive component 131, and the lifting driven sprocket 138 is connected to the input shaft of the steering box 134. The lifting drive sprocket 137 and the lifting driven sprocket 138 are connected by a lifting chain 136. The lifting drive component 131 is set on the translation frame 122. The lifting drive component 131 drives the lifting drive sprocket 137 to rotate. The lifting drive sprocket 137 drives the lifting driven sprocket 138 to rotate through the lifting chain 136. The lifting driven sprocket 138 drives the input shaft of the steering box 134 to rotate, ultimately realizing that the output shaft drives the lifting screw 135 to rotate and drives the lifting frame 133 to rise and fall.

[0045] By mounting the fixed frame 132 and the lifting drive component 131 on the translation frame 122, the translation drive component 121 can drive the lifting mechanism 13 to translate simultaneously when it drives the translation frame 122 to translate via the translation transmission assembly. The lifting drive component 131 drives the lifting frame 133 to lift via the lifting transmission assembly, so that when the conveyor 100 is supported on the lifting frame 133, the horizontal and vertical movement of the conveyor 100 can be realized. In addition, the lifting chain 136 in the lifting transmission assembly is only used to realize the transmission function, and the lifting screw 135 is also used to support the weight of the conveyor 100 when driving the lifting frame 133 to lift, thus avoiding the lifting chain 136 bearing the weight of the conveyor 100, improving the lifting stability and load-bearing capacity, and reducing the occurrence of safety accidents.

[0046] Optionally, the upper end of the frame 11 is provided with two spaced guide rail grooves 111 along the second horizontal direction; the translation frame 122 is provided with two sets of spaced rollers 1221 along the second horizontal direction, and the two sets of rollers 1221 are respectively rotatably disposed in the two guide rail grooves 111. By providing guide rail grooves 111 on the frame 11, the translation frame 122 can be rotatably disposed in the guide rail grooves 111 by the rollers 1221, which can effectively prevent the translation frame 122 from falling and reduce wear.

[0047] Furthermore, each set of rollers 1221 includes at least two rollers 1221 spaced apart along the first horizontal direction; the translation transmission assembly includes a translation chain 123, at least two translation linkage rods 124, a translation driven sprocket 125 disposed on each translation linkage rod 124, and a translation driving sprocket 126 disposed at the output end of the translation drive member 121. The translation driven sprocket 125 and the translation driving sprocket 126 are connected by the translation chain 123. The number of translation linkage rods 124 is equal to the number of rollers 1221 contained in each set of rollers 1221. The two ends of each translation linkage rod 124 are respectively connected to two corresponding rollers 1221 in the two sets of rollers 1221. The translation drive 121 drives the translation drive sprocket 126 to rotate, which in turn drives multiple translation driven sprockets 125 to rotate simultaneously via the translation chain 123. This, in turn, causes multiple translation linkage rods 124 to rotate simultaneously, ultimately causing the translation linkage rods 124 to drive the rollers 1221 at both ends to rotate, thus enabling the translation frame 122 to translate on the frame 11.

[0048] To ensure the stability of the conveyor 100 during transport, a lifting linkage rod 1311 is provided at the output end of the lifting drive 131, enabling the lifting drive 131 to drive the lifting linkage rod 1311 to rotate. Two fixed frames 132, two lifting frames 133, and two lifting transmission components are provided. The two fixed frames 132 are spaced apart on the translation frame 122 along the second horizontal direction. The two lifting frames 133 are movably connected to the two fixed frames 132 respectively. Two turning boxes 134 are respectively set on the two fixed frames 132. Two lifting drive sprockets 137 are spaced apart on the lifting linkage rod 1311. Two lifting driven sprockets 138 are respectively connected to the input shafts of the two turning boxes 134. The two lifting drive sprockets 137 are respectively connected to the two lifting driven sprockets 138 through two lifting chains 136. The upper ends of the two lifting screws 135 are respectively connected to the output shafts of the two turning boxes 134, and the two lifting screws 135 are respectively screwed to the two lifting frames 133. By placing the conveyor 100 between the two lifting frames 133, the overall structure is more stable under stress, making the conveying more stable.

[0049] Furthermore, such as Figure 3 and combined Figure 2As shown, the lifting frame 133 is provided with a slide groove 1331 extending along the second horizontal direction. In this embodiment, the slide groove 1331 is provided on the lifting beam at the lower part of the lifting frame 133, and the slide groove 1331 passes through the lifting beam along the second horizontal direction. A push-pull slide plate 1333 that can slide along the second horizontal direction is provided in the slide groove 1331. The push-pull slide plates 1333 on the two lifting frames 133 can slide closer to each other or slide further away from each other, so that the opposite ends of the push-pull slide plates 1333 on the two lifting frames 133 both extend out of the slide groove 1331 or retract into the slide groove 1331. When the opposite ends of the push-pull slide plates 1333 on the two lifting frames 133 both extend out of the slide groove 1331, the push-pull slide plate 1333 is used to carry the conveyor 100. By providing a sliding slide plate 1333, the slide plate 1333 can be slid out when the conveyor 100 needs to be transferred, to facilitate carrying the conveyor 100. When the conveyor 100 needs to be transferred to a designated position, the slide plate 1333 can be slid back into the chute 1331 to facilitate the placement of the conveyor 100. In this embodiment, the conveyor 100 is supported on the slide plate 1333 by a support plate 101.

[0050] In order to limit the push-pull slide plate 1333 and prevent it from moving out of the slide groove 1331, the upper end face of the lifting beam of the lifting frame 133 is also provided with a limiting groove 1332 that communicates with the slide groove 1331. The limiting groove 1332 passes through the lifting beam in a second horizontal direction. A limiting plate 1334 is provided on the push-pull slide plate 1333. The limiting plate 1334 is perpendicularly connected to the push-pull slide plate 1333. When the push-pull slide plate 1333 is slidably placed in the slide groove 1331, the limiting plate 1334 is slidably limited in the limiting groove 1332 to limit the push-pull slide plate 1333 and prevent it from falling out of the slide groove 1331.

[0051] The push-pull slide plate 1333 and the limiting plate 1334 can be connected by welding or screws. During installation, the push-pull slide plate 1333 needs to be slidably set in the slide groove 1331 first, and then the limiting plate 1334 is connected to the push-pull slide plate 1333.

[0052] Optionally, the translation drive 121 and the lifting drive 131 can be selected as motors.

[0053] Optionally, the lifting frame 133 is also provided with a push-pull drive component for driving the push-pull slide plate 1333 to slide, and the push-pull slide plate 1333 is connected to the output end of the push-pull drive component. By providing a push-pull drive component on each lifting frame 133, the push-pull drive component can drive the push-pull slide plate 1333 to slide, thereby increasing the overall automation level of the structure.

[0054] In this embodiment, each lifting frame 133 has two sliding grooves 1331 spaced apart along the first horizontal direction on its lifting beam. The push-pull drive component on each lifting frame 133 can simultaneously drive the two push-pull slide plates 1333 on each lifting frame 133 to slide.

[0055] To facilitate the simultaneous sliding of the two push-pull slide plates 1333 on each lifting frame 133, a connector 1335 is provided at the rear end of the two push-pull slide plates 1333 away from the conveyor 100. The connector 1335 is connected to both push-pull slide plates 1333 on the lifting frame 133, so that the connector 1335 and the two push-pull slide plates 1333 are integrated. The output end of the push-pull drive can be connected to the connector 1335 to drive the two push-pull slide plates 1333 to slide.

[0056] Alternatively, the push-pull drive can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder.

[0057] Of course, in other embodiments, the push-pull drive component may not be provided, and manual push-pull can also be used.

[0058] like Figure 4 As shown, this embodiment also provides an assembly line for assembling electrical distribution boxes. In this embodiment, the conveyor 100 is the electrical distribution box, and the assembly line realizes the conveying and transfer of the electrical distribution box at various workstations.

[0059] The assembly line includes a conveying module 2, a transport frame 1 set upstream and downstream of the conveying module 2 along a second horizontal direction, and an assembly platform 3 set on one or both sides of the conveying module 2 along a first horizontal direction. The transport frame 1 located upstream is used to transfer the distribution box to be assembled to the conveying module 2. The conveying module 2 is used to drive the distribution box to move on the conveying module 2 and to transfer the transported part 100 to the assembly platform 3. The assembly workers assemble the distribution box on the assembly platform 3.

[0060] This assembly line enables the automatic transfer and transportation of distribution boxes, improving assembly efficiency and ensuring high safety.

[0061] In this embodiment, there are eight assembly platforms 3, which are divided into two groups, and the two groups of assembly platforms 3 are respectively located on both sides of the conveying module 2.

[0062] Furthermore, the conveying module 2 includes a conveying frame 22 and a conveying trolley 21 mounted on the conveying frame 22 for carrying the conveyed component 100. The conveying trolley 21 moves back and forth on the conveying frame 22. The power distribution box is mounted on the conveying trolley 21. The movement of the power distribution box is achieved by moving the conveying trolley 21.

[0063] Furthermore, such as Figure 5As shown, the conveyor trolley 21 is equipped with a first driving component and multiple first rollers 211 spaced apart along a first horizontal direction. The first driving component drives the multiple first rollers 211 to rotate simultaneously. The assembly platform 3 is equipped with a second driving component and multiple second rollers 31 spaced apart along the first horizontal direction. The second driving component drives the multiple second rollers 31 to rotate simultaneously. When the conveyor trolley 21 transports the distribution box to a corresponding assembly platform 3, the first driving component drives the first rollers 211 to rotate, thereby moving the distribution box mounted on the conveyor trolley 21 to the assembly platform 3. When the distribution box is transported to the second rollers 31 of the assembly platform 3, the second driving component can also drive the second rollers 31 to rotate, cooperating with the first rollers 211 to move the distribution box to the assembly platform 3. When the distribution box on the assembly platform 3 needs to be transferred to the conveyor trolley 21, the first rollers 211 and the second rollers 31 rotate in opposite directions to move the assembled distribution box to the conveyor trolley 21. Through the cooperation of the conveyor trolley 21 and the assembly platform 3, human intervention is avoided, and the degree of automation is improved.

[0064] Each first roller 211 is provided with a first driven sprocket at one end, and a first driving sprocket is provided at the output end of the first driving member. Multiple first sprockets are connected to the first driving sprocket via a first chain, so that when the first driving member drives the first driving sprocket to rotate, it can drive multiple first driven sprockets to rotate simultaneously, thereby driving multiple first rollers 211 to rotate. The structure of the second driving member on the assembly platform 3 driving the second roller 31 to rotate is the same as the above structure, and will not be described again here.

[0065] In this embodiment, the first driving element and the second driving element can be selected as motors.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
