Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0034] During the vehicle production process, since the position for picking up the workpiece is on different sides from the position for installing the workpiece, the workpiece needs to be transferred from one position to another. The operator needs to walk back and forth between multiple workstations to transfer the workpiece, which consumes working hours and increases the physical exertion of the operator. This not only reduces production efficiency, but may also cause operator fatigue and operational errors.

[0035] In order to solve the technical problem, the utility model proposes a workpiece cross-line transportation system and a production line.

[0036] See also Figure 1 and Figure 2In one embodiment of the utility model, the workpiece cross-line transportation system includes a first lifting mechanism 100, a second lifting mechanism 200 and a transverse transportation mechanism 300. The first lifting mechanism 100 forms a pick-up position 101 and a transition position 102 at two ends along the vertical direction, and the transition position 102 is arranged above the pick-up position 101; the second lifting mechanism 200 and the first lifting mechanism 100 are arranged at intervals along the horizontal direction, and the second lifting mechanism 200 forms a receiving position 201 and a placing position 202 at two ends along the vertical direction, and the receiving position 201 is arranged above the placing position 202; the transverse transportation mechanism 300 is arranged between the first lifting mechanism 100 and the second lifting mechanism 200, and the transverse transportation mechanism 300 is arranged between the first lifting mechanism 100 and the second lifting mechanism 200. 00 forms a starting position 301 and an end position 302 at both ends along the horizontal direction, the starting position 301 is set corresponding to the transition position 102, and the end position 302 is set corresponding to the receiving position 201; wherein, the first lifting mechanism 100 includes a picking structure 110, and the picking structure 110 can pick up the workpiece at the picking position 101 and drive the workpiece to rise to the transition position 102; the horizontal transportation mechanism 300 includes a transportation structure 310, and the transportation structure 310 can receive the workpiece at the starting position 301 and drive the workpiece to move to the end position 302; the second lifting mechanism 200 includes a receiving structure 210, and the receiving structure 210 can receive the workpiece at the receiving position 201 and drive the workpiece to descend to the placing position 202.

[0037] It should be noted that the picking structure 110 can not only pick up the workpiece at the picking position 101 and drive the workpiece up to the transition position 102, but also can, after transferring the workpiece to the transport structure 310, descend from the transition position 102 to reset to the picking position 101, and the picking structure 110 can also stay at any position between the picking position 101 and the transition position 102; similarly, the receiving structure 210 can not only pick up the workpiece at the receiving position 201 and drive the workpiece down to the placing position 202, but also can, after taking the workpiece off, The receiving structure 210 rises from the placing position 202 and resets to the receiving position 201, and the receiving structure 210 can also stay at any position between the receiving position 201 and the placing position 202; the transport structure 310 can not only receive the workpiece at the starting position 301 and drive the workpiece to move to the end position 302, but also after transferring the workpiece to the receiving structure 210, it can move horizontally from the end position 302 and reset to the starting position 301, and the transport structure 310 can also stay at any position between the starting position 301 and the end position 302.

[0038] It should be understood that the first lifting mechanism 100 is used to transport the workpiece from the picking position to the transition position 102, the second lifting mechanism 200 is used to transport the workpiece from the transition position 102 to the installation position, and the transverse transport mechanism 300 is used to transport the workpiece transversely between the two lifting mechanisms to achieve cross-line transportation. First, the picking structure 110 picks up the workpiece at the picking position 101 and drives it up to the transition position 102, then the transport structure 310 transports the workpiece transversely from the transition position 102 to the receiving position 201, and finally, the receiving structure 210 receives the workpiece at the receiving position 201 and drives it down to the placing position 202. The entire workpiece transfer does not require the staff to move back and forth, which effectively solves the problem that the position where the workpiece is picked up and the position where the workpiece is installed on the vehicle production line are not on the same side.

[0039] In the technical solution provided by the present invention, the workpiece can be transferred across the line from the pickup position 101 to the placement position 202 through the first lifting mechanism 100, the second lifting mechanism 200 and the horizontal transportation mechanism 300. The operator does not need to walk back and forth between multiple workstations to transfer the workpiece, which greatly reduces manpower waste and operation time, reduces the physical exertion of the operator, prevents the operator from easily getting tired and causing operational errors, and improves the production efficiency and quality of the vehicle. In addition, the workpiece cross-line transportation system has a simple structure, is easy to operate, and is convenient to manage and maintain.

[0040] There are many implementation forms of the first lifting mechanism 100. In the embodiment of the present utility model, please refer to Figure 3 The first lifting mechanism 100 also includes a first guide member 120, which extends vertically. The two vertical ends of the first guide member 120 respectively form a pickup position 101 and a transition position 102; the pickup structure 110 is slidably disposed on the first guide member 120 along the vertical direction.

[0041] It should be noted that the first guide member 120 is formed by a guide rail and a bracket in the prior art.

[0042] It should be understood that in the entire workpiece cross-line transportation system, the first lifting mechanism 100 is a mechanism for initially transporting the workpiece, that is, a mechanism for taking the workpiece from the processing mechanism. The first lifting mechanism 100 realizes the function of safely and accurately transporting the workpiece from the pickup position 101 to the transition position 102, thereby providing a smooth relay for lateral transportation. The first guide member 120 plays the role of supporting and guiding the pickup structure 110 to move vertically, ensuring that the rising and falling movements of the pickup structure 110 are smooth and follow a predetermined trajectory. Since the first guide member 120 extends vertically, it itself needs to have sufficient rigidity and strength to withstand the weight of the pickup structure 110 and the stress generated during the movement, which can reduce vibration and deviation during movement and improve the accuracy of workpiece transfer. The vertical ends of the first guide member 120 respectively define a picking position 101 and a transition position 102, which means that the picking structure 110 performs rising and falling movements between these two positions. The picking position 101 is the initial position where the workpiece is picked up, and the transition position 102 is a temporary parking position before the workpiece is transported to the horizontal transport mechanism 300.

[0043] Specifically, in the embodiments of the present invention, please refer to Figure 4 The picking structure 110 includes a picking tray 111, a first adsorption member 112 and a first driving member. The picking tray 111 is slidably arranged on the first guide member 120 along the vertical direction. The first adsorption member 112 is installed at the bottom of the picking tray 111. The first adsorption member 112 is used to adsorb the workpiece. The first driving member is installed on the first guide member 120. The first driving member is connected to the picking tray 111. The first driving member is used to drive the picking tray 111 to drive the first adsorption member 112 to rise and fall between the transition position 102 and the picking position 101.

[0044] It should be noted that, when a plurality of first adsorption members 112 are disposed on the pickup tray 111 , the plurality of first adsorption members 112 are disposed at intervals.

[0045] It should be understood that the entire pickup structure 110 can safely and efficiently extract the workpiece, and ensure that the workpiece is not damaged or offset during the transportation between the pickup position 101 and the transition position 102, thereby improving the continuity of the vehicle production process. The pickup tray 111 is the main part of the pickup structure 110, which is composed of a platform or a bracket. The pickup tray 111 is slidably arranged on the first guide member 120 along the vertical direction to bear the weight of the workpiece. The first adsorption member 112 is installed at the bottom of the pickup tray 111 and is used to adsorb the workpiece. The first adsorption member 112 can be realized by various existing adsorption structures, such as vacuum suction cups, magnetic adsorption, etc., to ensure that the workpiece is firmly fixed during transportation. The first driving member is used to drive the pickup tray 111 to rise and fall between the transition position 102 and the pickup position 101. Existing driving structures such as electric motors, hydraulic devices or pneumatic devices can be used to realize the movement of the pickup structure 110.

[0046] There are many ways to implement the second lifting mechanism 200. In the embodiment of the present utility model, please refer to Figure 5 The second lifting mechanism 200 also includes a second guide member 220, which extends vertically. The two vertical ends of the second guide member 220 respectively form a receiving position 201 and a placing position 202; the connecting structure 210 is slidably arranged on the second guide member 220 along the vertical direction.

[0047] It should be noted that the second guide member 220 is formed by a guide rail and a bracket in the prior art.

[0048] It should be understood that the second guide member 220 provides a smooth and straight guide track in the vertical direction for the connecting structure 210, and plays a guiding and supporting role for the connecting structure 210. The vertical ends of the second guide member 220 correspond to the connecting position 201 and the placing position 202. The connecting structure 210 receives the workpiece brought by the horizontal transport mechanism 300 at the connecting position 201, and can move downward along the guide member to the placing position 202, so as to facilitate the operator to collect the workpiece and prepare for subsequent vehicle assembly or processing work.

[0049] Specifically, in an embodiment of the utility model, the receiving structure 210 includes a receiving tray 211, a second adsorption component 212 and a second driving component. The receiving tray 211 is slidably arranged on the second guide component 220 in the vertical direction. The second adsorption component 212 is installed on the top of the receiving tray 211. The second adsorption component 212 is used to adsorb the workpiece. The second driving component is installed on the second guide component 220. The second driving component is connected to the receiving tray 211. The second driving component is used to drive the receiving tray 211 to drive the second adsorption component 212 to rise and fall between the receiving position 201 and the placing position 202.

[0050] It should be noted that when a plurality of second adsorbents 212 are provided on the receiving tray 211, the plurality of second adsorbents 212 are arranged at intervals. The second adsorbent 212 can be implemented by various existing adsorption structures, such as vacuum suction cups, magnetic adsorption, etc. The second driving member can adopt existing driving structures such as motors, hydraulic devices or pneumatic devices.

[0051] It should be understood that the receiving tray 211 is slidably disposed on the second guide member 220 in the vertical direction, so that the workpiece can stably move up and down between the receiving position 201 and the placing position 202, thereby ensuring the transportation stability of the workpiece. The second adsorption member 212 is installed on the top of the receiving tray 211, and the second adsorption member 212 ensures the stability and safety of the workpiece during transportation. The workpiece will not slide or fall off when moving with the receiving structure 210, thereby ensuring the continuity and stability of the production line.

[0052] There are many forms of implementing the transverse transport mechanism 300. In the embodiment of the present utility model, please refer to Figure 6 The transverse transport mechanism 300 also includes a third guide member 320, which extends in the transverse direction. The two transverse ends of the third guide member 320 respectively form a starting position 301 and an end position 302; the transport structure 310 is slidably arranged on the third guide member 320 in the transverse direction.

[0053] It should be noted that the third guide member 320 is formed by a guide rail and a bracket in the prior art.

[0054] It should be understood that the third guide member 320 extends in the lateral direction to form a starting position 301 and an end position 302, providing a track and support for the operation of the lateral transport mechanism 300. The third guide member 320 ensures the lateral movement stability of the transport structure 310, avoiding the problem of offset or derailment that may occur during the transportation process, thereby making the operation of the entire system more reliable. The transport structure 310 always maintains connection with the third guide member 320 during the sliding process to ensure the stability and accuracy of the workpiece transportation process, thereby avoiding the problems of tilting and falling of the workpiece during the transportation process. The starting position 301 corresponds to the transition position 102 of the first lifting mechanism 100, and the end position 302 corresponds to the connection position 201 of the second lifting mechanism 200, ensuring that the lateral transport mechanism 300 forms a complete workpiece cross-line movement path between the first lifting mechanism 100 and the second lifting mechanism 200, so that the workpiece can accurately perform the next lifting operation after the lateral movement, thereby achieving the continuity of the production line.

[0055] Specifically, in an embodiment of the utility model, the transport structure 310 includes a hanging basket assembly 311, an adsorption assembly 312 and a third driving member. The hanging basket assembly 311 is slidably arranged on the third guide member 320 in the transverse direction. The adsorption assembly 312 is installed in the hanging basket assembly 311. The adsorption assembly 312 is used to adsorb the workpiece. The third driving member is connected to the hanging basket assembly 311. The third driving member is used to drive the hanging basket assembly 311 to drive the adsorption assembly 312 to move between the starting position 301 and the end position 302.

[0056] It should be noted that the third driving member may adopt an existing driving structure such as an electric motor, a hydraulic device or a pneumatic device.

[0057] It should be understood that the hanging basket assembly 311 is slidably arranged on the third guide member 320 in the transverse direction, forming the main frame of the transport structure 310. The hanging basket assembly 311 slides smoothly on the third guide member 320, ensuring the stability and controllability of the workpiece during the entire transportation process. The adsorption assembly 312 is installed inside the hanging basket assembly 311, and is used to firmly grasp the workpiece through the adsorption mechanism. The use of the adsorption assembly 312 is to ensure that the workpiece will not be displaced or dropped due to vibration or acceleration changes during transportation, thereby improving the safety and reliability of the workpiece during transportation. In addition, the adsorption assembly 312 is particularly suitable for processing workpieces with complex shapes or difficult to fix with conventional clamping methods, thereby improving the applicability of the present workpiece cross-line transportation system.

[0058] More specifically, in an embodiment of the utility model, the hanging basket assembly 311 includes a first frame 313, a second frame 314 and a connecting rod 315. The first frame 313 and the second frame 314 are longitudinally spaced to form a transfer gap. The first frame 313 and the second frame 314 form a loading space for carrying workpieces. The first frame 313 and the second frame 314 are slidably installed on the third guide member 320 along the transverse direction through the connecting rod 315, and the third driving member is connected to the connecting rod 315.

[0059] It should be understood that the first frame 313 and the second frame 314 are arranged at intervals in the longitudinal direction to form a transfer gap, allowing the workpiece to be stably placed between the first frame 313 and the second frame 314. The loading space surrounded by the first frame 313 and the second frame 314 is used to carry the workpiece, ensuring the safety and stability of the workpiece during the horizontal transportation process, and ensuring that the workpiece will not be displaced or tipped due to vibration or movement during transportation. The first frame 313 is connected to the second frame 314 by a connecting rod 315, which not only serves as a stabilizing element of the structure, but also provides the necessary mechanical strength and flexibility, so that the entire hanging basket assembly 311 can move smoothly on the third guide member 320, while maintaining an appropriate distance between the frames to accommodate workpieces of different sizes.

[0060] In an embodiment of the present utility model, the adsorption assembly 312 includes a third adsorption component 316 and a fourth adsorption component 317, both of which are used to adsorb workpieces. The third adsorption component 316 and the fourth adsorption component 317 are both arranged in the cargo space, the third adsorption component 316 is installed on the first frame 313, and the fourth adsorption component 317 is installed on the second frame 314.

[0061] It should be noted that when the first frame 313 is provided with a plurality of third adsorbents 316, the plurality of third adsorbents 316 are arranged at intervals. When the second frame 314 is provided with a plurality of fourth adsorbents 317, the plurality of fourth adsorbents 317 are arranged at intervals. The third adsorbents 316 and the fourth adsorbents 317 can be realized by various existing adsorption structures, such as vacuum suction cups, magnetic adsorption, etc.

[0062] It should be understood that the third adsorption member 316 is installed on the first frame 313, providing the ability to fix and adsorb a part of the workpiece in the cargo space, ensuring that one side of the workpiece can be firmly held in the hanging basket assembly 311. At the same time, the fourth adsorption member 317 is installed on the second frame 314, providing the ability to adsorb and fix the other side of the workpiece, so that both sides of the workpiece in the hanging basket assembly 311 can be firmly adsorbed, ensuring that the entire workpiece remains balanced and stable in the cargo space. The synergistic effect of the third adsorption member 316 and the fourth adsorption member 317 not only effectively solves the problem of fixing large or complex-shaped workpieces, so that the workpiece cross-line transportation system can handle workpieces of different specifications and sizes, and has good adaptability, but the third adsorption member 316 and the fourth adsorption member 317 also jointly ensure that the workpiece can remain stable during transportation, avoiding the problem of the workpiece sliding, tilting or falling.
