[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0051] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0052] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "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.
[0053] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or state relationships shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0054] The embodiments provided by this utility model offer a following connection structure, a following trolley including the following connection structure, and a production line including the following trolley or the following connection structure, to improve the ease of assembly and disassembly of the following trolley and its assembly and disassembly efficiency. It should be noted that the X direction refers to the width direction of the following trolley, and the Y direction refers to the length direction of the following trolley. The X and Y directions are perpendicular to each other with respect to the vertical direction. The production line direction refers to the direction from the start point to the end point of the production line. Since the production line direction is not necessarily a straight line, when the following trolley moves, its traveling direction, i.e., the Y direction, will change with the production line direction, causing the X direction to change accordingly.
[0055] like Figure 1 and Figure 2 As shown, the accompanying trolley includes a vehicle body 1, and an accompanying connection structure is installed on the vehicle body 1. The accompanying connection structure includes an accompanying connection unit 2, which includes an accompanying action part 211 and a first accompanying limiting part 212, both of which can extend out of the vehicle body 1 in the X direction. The accompanying action part 211 has an accompanying action surface 216, the facing direction of which is opposite to the production line direction. The first accompanying limiting part 212 has a first accompanying limiting surface 214 facing the vehicle body 1 in the X direction, and the first accompanying limiting part 212 protrudes from the accompanying action surface 216. Exemplarily, the accompanying action surface 216 and the first accompanying limiting surface 214 are connected in an L-shape. As an alternative, the accompanying action surface 216 and the first accompanying limiting surface 214 can also be arranged vertically at intervals.
[0056] The production line also includes a vehicle and a support structure for mounting the vehicle. The support structure is movable along the production line. The support structure includes a following pusher that is able to press against the following action surface 216 along the production line and against the first following limit surface 214 facing the vehicle body 1.
[0057] It should be noted that the production line can be a chassis sub-assembly line, an instrument sub-assembly line, or a door sub-assembly line, etc. Taking the door sub-assembly line as an example, the carrier is used to clamp and fix the basic parts. As the support structure moves along the production line with the carrier, the parts to be assembled are assembled one by one onto the basic parts.
[0058] The various components used in the assembly process are placed on the accompanying trolley, which is positioned on one side of the supporting structure in the X direction. The accompanying connecting unit 2, extending from the trolley body 1 in the X direction, is brought close to the supporting structure. Then, the accompanying trolley is pushed in the opposite direction along the production line, causing the accompanying pushing part to press against the accompanying action surface 216 and the first accompanying limiting surface 214. The production line is then controlled, and the supporting structure, carrying the carrier, moves along the production line. The accompanying pushing part pushes the accompanying connecting unit 2, causing the trolley body 1 to follow the supporting structure along the production line, thus enabling the accompanying trolley to move with the supporting structure. This allows tools and / or parts on the accompanying trolley to be readily available for easy access, thereby improving production line efficiency.
[0059] The accompanying propulsion unit propels the accompanying trolley, eliminating the need for a power source for the trolley, which is less expensive than a power-equipped trolley. Because no power source is required, the accompanying trolley is not limited by power sources and control systems, and is more flexible.
[0060] During the movement of the trolley following the support structure, since the following push part presses against the first following limiting surface 214 and the first following limiting surface 214 is set facing the vehicle body 1 in the X direction, it can prevent the trolley from moving away from the support structure in the X direction during the movement of the trolley, thereby limiting the trolley and preventing the trolley from deviating during the movement, thus improving the walking stability of the trolley.
[0061] When it is necessary to separate the accompanying trolley from the support structure, simply control the accompanying trolley to move relative to the support structure along the production line direction. Once the first accompanying limit surface 214 is completely disengaged from the accompanying push unit, move the accompanying trolley in the X direction, moving it away from the support structure, thus separating the entire accompanying trolley from the support structure. The assembly and disassembly method between the accompanying trolley and the support structure is simple, convenient, and quick. The structure is simple and practical, and only the aforementioned accompanying connection unit 2 needs to be installed on the trolley body 1, without requiring any modifications to the production line. It is highly versatile and low-cost.
[0062] In some embodiments, the following surface 216 is provided with a second following limit portion 213, and the second following limit portion 213 and the first following limit portion 212 are arranged at intervals; the second following limit portion 213 has a second following limit surface 215 facing the first following limit portion 212.
[0063] For example, a U-shaped following groove 217 is formed between the second following limit part 213 and the first following limit part 212, and the opening of the following groove 217 faces the same direction as the production line. It should be noted that the second following limit part 213 and the first following limit part 212 can also be arranged vertically at intervals.
[0064] The following pusher is inserted into the following groove 217 along the production line until the following pusher presses against the bottom wall of the following groove 217. The following pusher is clamped between the first following limit surface 214 and the second following limit surface 215 in the X direction. This helps to prevent the following trolley from deviating when following the support structure and improves the walking stability of the following trolley.
[0065] In some embodiments, the accompanying connection structure further includes an accompanying mounting base 3, which is mounted on the vehicle body 1. The accompanying connection unit 2 is movably connected to the accompanying mounting base 3, enabling the accompanying connection unit 2 to switch between a use state and a storage state. When the accompanying connection unit 2 is in the use state, the maximum length of the accompanying connection unit 2 extending out of the vehicle body 1 in the X direction is W1. When the accompanying connection unit 2 is in the storage state, the maximum length of the accompanying connection unit 2 extending out of the vehicle body 1 in the X direction is W2. W1 is greater than W2.
[0066] When the accompanying trolley is not in use, the accompanying connection unit 2 can be switched to the storage state, reducing the maximum length of the accompanying connection unit 2 extending out of the vehicle body 1 in the X direction and reducing the space occupied by the accompanying trolley in the X direction. When the accompanying trolley is in use, the accompanying connection unit 2 is switched to the use state, so that the accompanying connection unit 2 extends out of the vehicle body 1 in the X direction, making it easier to connect the accompanying connection unit 2 to the support structure of the mounting vehicle.
[0067] In some embodiments, when the accompanying connection unit 2 is in a retracted state, it is at least partially retracted inside the vehicle body 1. For example, the accompanying connection unit 2 is located at the top of the vehicle body 1, and is rotatably connected to the accompanying mounting base 3 about a first axis extending along the production line. When the accompanying connection unit 2 is in the retracted state, it is completely located inside the vehicle body 1. After switching the accompanying connection unit 2 to the retracted state, it does not occupy the vehicle body 1 at all.
[0068] As an alternative, the first axis can also extend in a vertical direction. When the accompanying connecting unit 2 is in use, the side of the accompanying connecting unit 2 away from the first axis can be moved closer to or away from the vehicle body 1 by rotating the accompanying connecting unit 2.
[0069] As an alternative, the portion of the accompanying connecting unit 2 extending out of the vehicle body 1 in the X direction is adjustable relative to the vehicle body 1 in the X direction. Specifically, the positions of the accompanying action part 211 and / or the first accompanying limiting part 212 relative to the vehicle body 1 in the X direction are adjustable. For example, the accompanying connecting unit 2 can be a threaded rod extending in the X direction, threadedly connected to the vehicle body 1. By tightening the threaded rod, the relative position between the accompanying connecting unit 2 and the vehicle body 1 can be adjusted in the X direction. Alternatively, a fixed rod can be mounted on the vehicle body 1, forming a telescopic structure that is retractable in the X direction as in the prior art, which will not be described in detail here. Another option is to use a telescopic rod that is retractable in the X direction as the entire accompanying connecting unit 2.
[0070] In some embodiments, the accompanying connection unit 2 further includes a support rod 22, one end of which is rotatably connected to the accompanying mounting base 3, and the other end is connected to the accompanying action part 211; when the accompanying connection unit 2 is in use, the accompanying action part 211 is located above the support rod 22.
[0071] The height of the vehicle body 1 is generally at a height that allows operators to manually pick up and put down parts and tools. The accompanying push unit is generally higher than the vehicle body. When the accompanying connecting unit 2 is in use, the height of the accompanying action part 211 is relatively high through the support rod 22, which facilitates the cooperation between the accompanying connecting unit 2 and the accompanying push unit.
[0072] In some embodiments, the accompanying connection unit 2 is connected to a handle 7. Exemplarily, the handle 7 is connected to the accompanying action part 211 and located on the side of the accompanying action part 211 opposite to the accompanying action surface 216. When the accompanying connection unit 2 is in use, its height is relatively high. By placing the handle 7 on the accompanying connection unit 2, the operator can easily grasp the handle 7 and rotate the accompanying connection unit 2 without bending over, making operation convenient. Alternatively, the handle 7 can also be mounted on the support rod 22.
[0073] In some embodiments, one end of the handle 7 extends out of the vehicle body 1 along the Y direction. When the accompanying connection unit 2 is in the retracted state, since one end of the handle 7 extends out of the vehicle body 1 along the Y direction, it is convenient for the operator to hold the handle 7 and switch the accompanying connection unit 2 from the retracted state to the use state.
[0074] In some embodiments, the accompanying connection structure further includes a balancing member 4, which includes a first balancing portion 41 and a second balancing portion 42. The first balancing portion 41 has a first balancing surface 411 with the same facing direction as the accompanying action surface 216. The second balancing portion 42 protrudes from the first balancing surface 411 and has a second balancing surface 421, which faces in the opposite direction to the first accompanying limiting surface 214. Exemplarily, the first balancing surface 411 can press against the accompanying pusher along the production line, and the second balancing surface 421 can press against the accompanying pusher in a direction opposite to the vehicle body 1. The first balancing surface 411 and the second balancing surface 421 are connected in an L-shaped arrangement.
[0075] When the above-mentioned following connection structure is applied to the following vehicle, the balance member 4 can extend at least partly out of the vehicle body 1 in the X direction, so that the part of the balance member 4 extending out of the vehicle body 1 and the part of the following connection unit 2 extending out of the vehicle body 1 are located on the same side of the vehicle body 1.
[0076] When the accompanying push unit is inserted into the accompanying slot 217, the first balancing surface 411 presses against the support structure along the production line, and the second balancing surface 421 presses against the support structure. This achieves the distribution of the passive traction force on the accompanying connecting unit 2 by using the balancing component 4, preventing the accompanying connecting unit 2 from being stressed and deformed due to only the accompanying connecting unit 2 being subjected to force, thus making the accompanying trolley more stable and durable.
[0077] As an alternative, the second balancing surface 421 can be oriented in the same direction as the first accompanying limiting surface 214; two second balancing parts 42 can be protruded from the first balancing surface 411 and spaced apart along the X direction, with each of the two opposite sides of the two second balancing parts 42 forming a second balancing surface 421, and the accompanying pushing part can be inserted between the two second balancing parts 42 along the Y direction and sandwiched between the two second balancing surfaces 421 along the X direction.
[0078] In some embodiments, the accompanying connection structure further includes a balance mounting base 5, which is mounted on the vehicle body 1. The balance component 4 is movably connected to the balance mounting base 5, so that the balance component 4 can switch between a use state and a storage state. When the balance component 4 is in the use state, the maximum length of the balance component 4 extending out of the vehicle body 1 in the X direction is L1. When the balance component 4 is in the storage state, the maximum length of the balance component 4 extending out of the vehicle body 1 in the X direction is L2. L1 is greater than L2.
[0079] When the accompanying trolley is not in use, the balancing component 4 can be switched to the retracted state, reducing the maximum length of the balancing component 4 extending out of the vehicle body 1 in the X direction and reducing the space occupied by the accompanying trolley in the X direction. When the accompanying trolley is in use, the balancing component 4 is switched to the use state, so that the balancing component 4 extends out of the vehicle body 1 at least partially in the X direction, making it easier to connect the balancing component 4 to the support structure of the mounting vehicle.
[0080] Specifically, the balancing component 4 is rotatably connected to the balancing mounting base 5 around the second axis. By rotating the balancing component 4, the end of the balancing component 4 away from the vehicle body 1 is continuously moved closer to the vehicle body 1, thereby switching the balancing component 4 from the use state to the storage state. For example, the second axis extends along the Y direction.
[0081] As an alternative, the second axis can also be extended vertically or along the X direction.
[0082] As an alternative, the portion of the balancing component 4 extending out of the vehicle body 1 along the X direction can be adjusted relative to the vehicle body 1 along the X direction. Specifically, the positions of the first balancing part 41 and / or the second balancing part 42 relative to the vehicle body 1 along the X direction are adjustable. For example, the balancing component 4 can be a threaded rod extending along the X direction, threadedly connected to the vehicle body 1. By tightening the threaded rod, the relative position between the balancing component 4 and the vehicle body 1 can be adjusted along the X direction. Alternatively, a balancing fixing rod can be installed on the vehicle body 1. The balancing component 4 and the fixing rod constitute a telescopic structure that is retractable along the X direction in the prior art, which will not be described in detail here. Another option is that the entire balancing component 4 can be a telescopic rod that is retractable along the X direction in the prior art.
[0083] In some embodiments, the accompanying connection unit 2 is movably connected to the accompanying mounting base 3, and the balancing component 4 is movably connected to the balancing mounting base 5. The accompanying connection structure also includes a linkage component 6, through which the accompanying connection unit 2 is connected to the balancing component 4. The linkage component 6 is configured to enable the accompanying connection unit 2 and the balancing component 4 to move synchronously, so that the accompanying connection unit 2 and the balancing component 4 can be selectively both in use or both in storage.
[0084] The linkage 6 enables the accompanying connection unit 2 and the balancing component 4 to move synchronously, so that when the accompanying connection unit 2 is in use, the balancing component 4 is also in use, and when the accompanying connection unit 2 is in storage, the balancing component 4 is also in storage.
[0085] For example, the accompanying connection unit 2 is rotatably connected to the accompanying mounting base 3 about a first axis, the balancing member 4 is rotatably connected to the balancing mounting base 5 about a second axis, the linkage member 6 is rotatably connected to the accompanying connection unit 2 about a third axis, and the linkage member 6 is rotatably connected to the balancing member 4 about a fourth axis. The first, second, third, and fourth axes extend in the same direction. In other words, the first, second, third, and fourth axes are arranged in parallel.
[0086] Taking a scenario where the first axis, second axis, third axis, and fourth axis all extend along the Y direction, the balancing component 4 is located below the accompanying connecting unit 2, the balancing component 4 is located on one side of the vehicle body 1 in the X direction, and the accompanying connecting unit 2 is located on the top of the vehicle body 1, by rotating the accompanying connecting unit 2, the end of the accompanying connecting unit 2 away from the first axis continuously approaches the top of the vehicle body 1. The accompanying connecting unit 2 pulls the linkage 6 to drive the balancing component 4 to rotate upward around the second axis, so that the end of the balancing component 4 away from the second axis continuously approaches the vehicle body 1. During this process, the rotation directions of the accompanying connecting unit 2 and the balancing component 4 are the same.
[0087] As an alternative, the first, second, third, and fourth axes can all be aligned vertically. Whether using the accompanying trolley or storing the accompanying connecting unit 2 and the balancing component 4, the accompanying connecting unit 2 and the balancing component 4 are always located on the same side of the vehicle body 1. It should be noted that when the accompanying trolley moves along the production line, the part of the trolley in front is the front of the vehicle, and the part behind is the rear of the vehicle. When switching the accompanying connecting unit 2 and the balancing component 4 from the used state to the stored state, both the accompanying connecting unit 2 and the balancing component 4 rotate backward, causing the ends of the accompanying connecting unit 2 and the balancing component 4 that are away from their own rotation axes to continuously move closer to the rear of the vehicle.
[0088] In some embodiments, such as Figures 1 to 4 As shown, the accompanying mounting base 3 has a first limiting support portion 311 and a second limiting support portion 312. When the accompanying connecting unit 2 is in use, along the rotation direction of the accompanying connecting unit 2 from the storage state to the use state, the accompanying connecting unit 2 is supported by the first limiting support portion 311; when the accompanying connecting unit 2 is in the storage state, along the rotation direction of the accompanying connecting unit 2 from the use state to the storage state, the accompanying connecting unit 2 is supported by the second limiting support portion 312. For example, the accompanying mounting base 3 is mounted on the top of the vehicle body 1.
[0089] Specifically, the accompanying connection unit 2 also includes a linkage connector 23 connected to the support rod 22. The linkage connector 23 is connected to the end of the support rod 22 away from the accompanying action part 211. The connection part of the linkage connector 23 and the support rod 22 is rotatably connected to the accompanying mounting base 3 around the first axis. The linkage connector 23 is rotatably connected to the linkage member 6 around the third axis.
[0090] For example, the accompanying mounting base 3 includes a first mounting body 31, one end of which is fixed to the vehicle body 1 and the other end extends out of the vehicle body 1 in the X direction. The upper surface of the first mounting body 31 is provided with accompanying mounting ears 32 arranged at intervals in the Y direction. The connecting part of the linkage connector 23 and the support rod 22 is placed between the two accompanying mounting ears 32 and is rotatably connected to the two accompanying mounting ears 32 around the first axis.
[0091] For example, along the X direction, the first mounting bodies 31 on both sides of the first axis form a first limiting support portion 311 and a second limiting support portion 312 respectively. Along the X direction, the second limiting support portion 312 is closer to the center of the vehicle body 1 than the first limiting support portion 311.
[0092] When the accompanying connection unit 2 is in use, the linkage connector 23 presses downward against the first limiting support part 311, and the first limiting support part 311 supports the accompanying connection unit 2. When switching the accompanying connection unit 2 from the use state to the storage state, the accompanying connection unit 2 is rotated, so that the end of the accompanying connection unit 2 away from the second mounting base 51 moves closer to the top of the vehicle body 1 until the support rod 22 presses downward against the second limiting support part 312, and the second limiting support part 312 supports the accompanying connection unit 2.
[0093] When the accompanying connection unit 2 is in use, the first limiting support 311 limits the accompanying connection unit 2 to ensure that the accompanying connection unit 2 is stably maintained in the use state, and also serves to remind the operator that the accompanying connection unit 2 has been switched to the use state. When the accompanying connection unit 2 is in the storage state, the second limiting support 312 limits the accompanying connection unit 2 to ensure that the accompanying connection unit 2 is stably maintained in the storage state, and also serves to remind the operator that the accompanying connection unit 2 has been switched to the storage state.
[0094] As an alternative, when the accompanying connection unit 2 adopts a telescopic rod that can extend and retract along the X direction, and the balance member 4 also adopts a telescopic rod that can extend and retract along the X direction, one end of the linkage member 6 is connected to the accompanying connection unit 2 and the other end is connected to the balance member 4. By pushing and pulling the linkage member 6, the accompanying connection unit 2 and the balance member 4 can extend and retract synchronously along the X direction.
[0095] In some embodiments, when the balancer 4 is in use, it is supported by the balancer mounting base 5. The balancer mounting base 5 not only serves to mount the balancer 4, but also to support the balancer 4 when it is in use.
[0096] Taking the balancing component 4 rotatably connected to the balancing mounting base 5 as an example, the balancing mounting base 5 includes a second mounting body 51. One end of the second mounting body 51 is fixed to the vehicle body 1, and the other end extends out of the vehicle body 1 along the X direction. Two balancing mounting ears 52 are fixed on the upper surface of the second mounting body 51 and are spaced apart along the Y direction. One end of the first balancing part 41 is placed between the two balancing mounting ears 52 and rotatably connected to the two balancing mounting ears 52. The second balancing part 42 is connected to the part of the first balancing part 41 that extends out of the two balancing mounting ears 52. When the balancing component 4 is in use, the first balancing part 41 is pressed downward against the second mounting body 51. When switching the balancing component 4 from the use state to the storage state, the balancing component 4 is rotated upward, so that the end of the balancing component 4 away from the second mounting body 51 continuously approaches the vehicle body 1.
[0097] In some embodiments, the linkage 6 is a U-shaped rod with a gradually widening opening. When both the accompanying connecting unit 2 and the balancing member 4 are in use, the linkage 6 and the balancing member 4 are located on the same side of the vehicle body 1, and the opening of the U-shaped rod faces the vehicle body 1 along the X direction. With the above arrangement, when the accompanying connecting unit 2 and the balancing member 4 are operated synchronously using the linkage 6, interference between the U-shaped rod and the vehicle body 1 can be avoided.
[0098] In some embodiments, the vehicle body 1 includes a frame 11 and a partition 12 mounted on the frame 11, wherein at least two partitions 12 are arranged vertically at intervals. Exemplarily, three partitions 12 are provided to facilitate the placement of smaller parts or tools on the partitions 12. It should be noted that the number of partitions 12 can be arranged according to actual needs.
[0099] In some embodiments, at least three casters 13 are mounted on the bottom of the frame 11, and the at least three casters 13 are arranged at circumferential intervals along the frame 11. Exemplarily, four casters 13 are provided, the frame 11 is a rectangular frame made of aluminum alloy profile, and the four casters 13 are respectively arranged at the four corners of the frame 11. By employing casters 13, the smoothness of the accompanying vehicle's movement can be improved.
[0100] The installation process between the accompanying trolley and the supporting structure provided by this utility model is as follows:
[0101] Place the trolley on one side of the support structure in the X direction, and switch both the trolley connecting unit 2 and the balancer 4 to the working state; align the opening of the trolley groove 217 with the trolley pushing part, and then push the trolley from the bottom wall of the trolley groove 217 to the opening of the trolley groove 217 until it can no longer be pushed, indicating that the trolley pushing part is pressing against the trolley action surface 216 along the production line; at this time, the trolley pushing part is sandwiched between the first trolley limiting surface 214 and the second trolley limiting surface 215 in the X direction, and the trolley pushing part is pressing against the first balance surface 411 along the production line, and the trolley pushing part is pressing against the second balance surface 421 in the direction facing the vehicle body 1, thus completing the installation between the trolley and the support structure.
[0102] The disassembly process between the accompanying trolley and the supporting structure is as follows:
[0103] The traveling trolley is pushed along the direction from the opening of the traveling groove 217 to the bottom wall of the groove, so that the traveling push unit exits the traveling groove 217. At this time, the traveling push unit separates from the second balance surface 421 along the production line. Then the traveling trolley is pushed to move in the X direction, so that the traveling trolley moves away from the support structure until the traveling trolley has completely moved to one side of the support structure, thus completing the disassembly between the traveling trolley and the support structure.
[0104] The process of switching from the usage state to the storage state for the accompanying connection unit 2 and the balancing component 4 is as follows:
[0105] Hold the handle 7 and push the handle 7 so that the end of the following connection unit 2 away from the first axis approaches the top of the vehicle body 1. The following connection unit 2 drives the balance member 4 to rotate upward around the second axis through the linkage member 6, so that the end of the balance member 4 away from the second axis continuously approaches the vehicle body 1 until the support rod 22 presses down against the second limit support part 312, that is, both the following connection unit 2 and the balance member 4 are switched to the storage state.
[0106] The process of switching from the storage state to the usage state of the accompanying connection unit 2 and the balancing component 4 is as follows:
[0107] Hold the handle 7 and push the handle 7, so that the end of the following connection unit 2 away from the first axis continuously moves away from the top of the vehicle body 1. The following connection unit 2 pushes the balance member 4 to rotate downward around the second axis through the linkage member 6, so that the end of the balance member 4 away from the second axis continuously moves away from the vehicle body 1 until the linkage connection member 23 presses down onto the first limit support part 311. At this time, the first balance part 41 presses down onto the first mounting base 31, that is, both the following connection unit 2 and the balance member 4 are switched to the use state.
[0108] Taking a 45JPH production line as an example, the accompanying trolley provided in this embodiment of the invention follows the support structure, making it convenient and quick for operators to pick up and put down parts and tools. This not only improves operational efficiency, saving 8 seconds of material handling time per operation cycle, but also reduces the operator's workload. Compared with existing technologies, the operator's walking distance can be shortened by 50%. JPH is an abbreviation for Jobs Per Hour, representing the hourly or unit-time workload, reflecting the theoretical production capacity of a single process equipment, process unit, or production line.
