[0050] See Figure 1 and Figure 2 This utility model provides a misaligned conveying device, including a fixed-height bearing platform 1, a floating bearing platform 2, a transverse direct drive mechanism 3, and a longitudinal guide mechanism 4.

[0051] The transverse direct drive mechanism 3 is connected to the two bearing platforms respectively, and is used to drive the two bearing platforms to move in opposite directions, so as to drive the two bearing platforms to alternate between the first station and the second station;

[0052] The longitudinal guide mechanism 4 is located below the floating support platform 2 and is used to guide the floating support platform 2 to move upward at the first work station and the second work station to a position level with the fixed height support platform 1, and to move downward between the first work station and the second work station to a position lower than the fixed height support platform 1 in order to avoid the fixed height support platform 1.

[0053] The misaligned conveying device provided in this embodiment operates as follows:

[0054] S10: Initial state: Fixed-height bearing platform 1 is located at the first work station, floating bearing platform 2 is located at the second work station, and the two bearing platforms are at the same horizontal height.

[0055] S20: Workpiece placement: The unloading robot and other similar devices place the workpiece on the fixed-height bearing platform 1 at the first station, while the picking robot and other similar devices remove the workpiece from the floating bearing platform 2 at the second station.

[0056] S30: Lateral movement: Activate the lateral direct drive mechanism 3, causing the fixed-height load-bearing platform 1 and the floating load-bearing platform 2 to move in opposite directions:

[0057] S301: On the one hand, the fixed-height load-bearing platform 1 moves directly from the first workstation to the second workstation;

[0058] S302: On the other hand, the floating support platform 2 moves from the second workstation to the first workstation;

[0059] During this process:

[0060] The longitudinal guide mechanism 4 first guides the floating bearing platform 2 to move downward from the second station to a lower position so that it will not collide with the fixed-height bearing platform 1 when it encounters it later. After reaching the first station, the longitudinal guide mechanism 4 guides the floating bearing platform 2 to move upward from the lower position and reset it to the same height as the fixed-height bearing platform 1.

[0061] S40: Repeated operation: At this time, the floating support platform 2 has reached the first station and the fixed height support platform 1 has reached the second station. The material feeding robot and the material picking robot can continue to place and pick up the workpieces.

[0062] In the above process, the two carrier platforms can carry out transportation operations synchronously without collision, thereby solving the problem that the existing conveying device has only one carrier platform, resulting in low transportation efficiency.

[0063] The longitudinal guide mechanism 4 includes a high first support surface 401 located at the first work station, a high second support surface 402 located at the second work station, and an intermediate low support surface 403 located between the high first support surface 401 and the high second support surface 402.

[0064] The high-position first support surface 401 and the high-position second support surface 402 are flush, and both the high-position first support surface 401 and the high-position second support surface 402 are higher than the middle low-position support surface 403.

[0065] Optionally, both the high-position first support surface 401 and the high-position second support surface 402 are provided with inclined transition surfaces 404 between them and the intermediate low-position support surface 403.

[0066] In step S302 above, the floating bearing platform 2 is first guided downward by the longitudinal guide mechanism 4 at the second station, and moves to the middle low support surface 403 through the inclined transition surface 404. At this time, the height of the floating bearing platform 2 is lower than that of the fixed height bearing platform 1, thus avoiding collision when the two meet.

[0067] When the floating support platform 2 moves laterally to the first working position, it continues to rise to the high-level first support surface 401 through the inclined transition surface 404 under the action of the longitudinal guide mechanism 4, reaching the same horizontal height as the fixed-height support platform 1.

[0068] In this embodiment, the floating support platform 2 includes a fixed-height base 201, a workpiece carrier plate 202, a linear bearing 203, a support plate 204, and rollers 205.

[0069] The fixed-height base 201 is connected to the drive end of the transverse direct drive mechanism 3 and is driven by the transverse direct drive mechanism 3 to reciprocate at a constant horizontal height; the workpiece carrier plate 202 is slidably connected to the fixed-height base 201.

[0070] The linear bearing 203 is mounted on the fixed height base 201, and the bottom of the workpiece carrier plate 202 has a guide rod 2021 that is slidably connected to the linear bearing 203.

[0071] The guide slide rod 2021 is fixed to the top of the support plate 204. The roller 205 is installed on the support plate 204 and is used to roll along the high first support surface 401, the middle low support surface 403, and the high second support surface 402, so that the workpiece carrier plate 202 floats up and down with the height changes of the high first support surface 401, the middle low support surface 403, and the high second support surface 402.

[0072] Optionally, the transverse direct drive mechanism 3 is a motor belt assembly. Specifically, the motor belt assembly includes a first straight belt segment 301 and a second straight belt segment 302 with opposite directions of movement. The fixed-height bearing platform 1 is fixed on the first straight belt segment 301, and the fixed-height base 201 is fixed on the second straight belt segment 302.

[0073] The floating support platform 2 consists of two parts: a fixed-height base 201 and a workpiece carrier plate 202, allowing the workpiece carrier plate 202 to slide up and down on the fixed-height base 201. This design allows the floating support platform 2 to move laterally while also floating up and down under the guidance of the longitudinal guide mechanism 4, thus avoiding collisions when two support platforms meet. Guide rods 2021 are fixed on the support plate 204, and rollers 205 are installed on the support plate 204, allowing the workpiece carrier plate 202 to float up and down as the height of the support surface changes.

[0074] In this embodiment, the first straight belt segment 301 is located above the second straight belt segment 302. Since the floating support platform 2 needs to move downwards to avoid obstacles, fixing the fixed-height base 201 to the lower-positioned second straight belt segment 302 helps reduce the difficulty of the obstacle avoidance design for the floating support platform 2 and improves the structural compactness.

[0075] The misaligned conveying device provided in this embodiment has the following advantages:

[0076] ① Improve transportation efficiency: By adopting a design that alternates between two bearing platforms (fixed height bearing platform 1 and floating bearing platform 2), continuous workpiece placement and removal operations can be realized, which greatly improves the working efficiency of the conveying device and solves the problem of low efficiency of traditional single bearing platform conveying devices.

[0077] ② Collision avoidance: The longitudinal guide mechanism 4 of the floating bearing platform 2 enables it to float up and down during lateral movement, effectively avoiding collisions with the fixed-height bearing platform 1 during the repositioning process, thus improving the safety and reliability of the equipment.

[0078] ③ Precise guidance: By setting linear bearing 203 and guide slide 2021, as well as support plate 204 and roller 205, the precise guidance and stable movement of workpiece carrier plate 202 when floating up and down are ensured, thus guaranteeing the machining accuracy of the workpiece.

[0079] ④ Compact structure: The design of the floating support platform 2 allows it to float longitudinally while moving laterally. This compact structure saves space and is suitable for various production environments.

[0080] ⑤ Easy to maintain: The motor belt assembly, as a transverse direct drive mechanism 3, has the characteristics of simple structure and convenient maintenance, which reduces the maintenance cost of the equipment.

[0081] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
