Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting device for a stamping end-collector storage trolley. Background Technology

[0002] The end effector is a customized picking mechanism for stamped parts. To avoid confusion among end effectors, they are classified and fixed by model using a storage trolley. The storage trolley can also directly transport spare end effectors to the stamping machine for quick disassembly and maintenance.

[0003] The storage trolleys are stored in an automated warehouse. The trolleys are first lifted by a lifting device to be level with the conveyor device, which then transports them into the automated warehouse. The existing lifting device has a fixed direction, so the storage trolleys cannot be turned. For different types and orientations of automated warehouses, the installation direction and position need to be adjusted in conjunction with the lifting device, which results in insufficient compatibility. Furthermore, the storage trolleys are prone to swaying and displacement during lifting or turning, posing a risk of tipping over or slipping, resulting in poor stability and affecting the safety of transportation. Summary of the Invention

[0004] This utility model provides a lifting device for a stamping end-capsule storage trolley. The upper lifting platform and the stamping end-capsule storage trolley rotate synchronously in a circumferential direction to achieve the turning operation of the storage trolley. This improves the compatibility of the upper lifting platform with different placement directions of storage trolleys in different automated warehouses. The side positioning frame is adjusted at intervals as the positioning connecting slide moves to achieve compatibility with storage trolleys of different lengths. During the lifting and lowering process of the upper lifting platform, the pulleys of the stamping end-capsule storage trolley fall into the groove formed by the downward movement of the side positioning frame on the positioning connecting slide, thereby limiting the movement of the stamping end-capsule storage trolley and preventing swaying and displacement during the lifting, lowering and turning process of the storage trolley.

[0005] This utility model provides a lifting device for a stamping end-capsulator storage trolley, specifically including an upper lifting platform, side positioning frames, and a scissor lift frame. Side positioning frames are symmetrically arranged on both sides of the upper lifting platform. The lower part of the upper lifting platform is rotatably connected to the scissor lift frame via bearing rings. Slidingly connected positioning connecting slides are symmetrically arranged on both sides of the upper lifting platform. Side support bars are arranged in an array at intervals on both sides of the positioning connecting slides. The side support bars are slidably connected to the slide grooves of the upper lifting platform, forming a grid support surface to meet the movement requirements of the storage trolley's pulleys. Side tightening screws are threadedly connected to the side of the upper lifting platform, and these screws are in tight contact with the positioning connecting slides. The side positioning frames can slide synchronously with the positioning connecting slides.

[0006] Furthermore, a lower support frame is fixedly connected to the lower part of the side positioning frame, and a lower connecting spring is fixedly connected to the first end of the lower support frame.

[0007] Furthermore, the upper end of the lower connecting spring is fixedly connected to the upper lifting platform, the side positioning frame and the positioning connecting slide are slidably connected, and the lower support frame is located below the upper lifting platform. When the scissor lift platform rises, the lower support slide and the lower base separate, and the lower support slide, the lower support frame and the side positioning frame move down synchronously. The pulley of the end effector trolley falls into the groove formed by the downward movement of the side positioning frame in the positioning connecting slide.

[0008] Furthermore, both sides of the scissor lift platform are symmetrically provided with slidingly connected lower support slides. A central drive motor is fixedly connected to the center of the scissor lift platform. The scissor lift platform is located inside the lower base. The lower ends of the scissor frames on both sides of the scissor lift platform are slidably connected to the lower base. The scissor lift platform has the same structure as the existing lifting frame, which achieves lifting and lowering by expanding and retracting the scissor frames on both sides in conjunction with the extension and retraction of the hydraulic telescopic rod.

[0009] Furthermore, the lower support slide is located below the lower support frame, and the rotating shaft of the middle drive motor is fixedly connected to the center of the upper lifting platform. The middle drive motor drives the upper lifting platform to rotate, thereby realizing the horizontal adjustment of the upper lifting platform to match the docking requirements of storage trolleys in different orientations and placement angles.

[0010] Furthermore, when the scissor lift platform is in its lowest state, the top surface of the upper lifting platform and the top surface of the lower base are flush, and the top of the lower support slide and the bottom of the lower support frame are in contact.

[0011] Furthermore, when the top of the lower support slide and the bottom of the lower support frame are in contact, the top of the side positioning frame and the top of the positioning connecting slide remain flush and locked, and the side positioning frame, the positioning connecting slide, and the upper lifting platform are flush to form a complete and flat bearing plane.

[0012] This utility model provides a lifting device for a stamping end-cap device storage trolley, which has the following advantages: The upper lifting platform and the stamping end pick-up device rotate synchronously in a circumferential direction to enable the storage trolley to turn, improving the compatibility of the upper lifting platform with different storage trolley placement directions in different automated warehouses. The side positioning frame adjusts the interval distance as the positioning connecting slide moves, achieving compatibility with storage trolleys of different lengths. One device can meet the lifting and transfer needs of multiple models of storage trolleys in the workshop, significantly improving the equipment's versatility.

[0013] The side positioning frame and the pulleys of the stamping end-collector storage trolley are aligned. During the lifting and lowering process of the upper lifting platform, the pulleys of the stamping end-collector storage trolley fall into the groove formed by the downward movement of the side positioning frame of the positioning connecting slide, thereby limiting the stamping end-collector storage trolley and preventing swaying and displacement during the lifting, lowering and turning processes, thus improving stability.

[0014] After the upper lifting platform falls to its lowest point, the lower support slide holds against the lower support frame, making the top of the side positioning frame and the positioning connecting slide flush. The planar structure makes it easy for the stamping end pick storage trolley to move in and out of the work along the upper lifting platform without the need for manual lifting or auxiliary pushing, thus improving the ease of operation.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a lifting device for a stamping end effector storage trolley, including an upper lifting platform 1, side positioning frames 2, and a scissor lift frame 3. Side positioning frames 2 are symmetrically arranged on both sides of the upper lifting platform 1. The lower part of the upper lifting platform 1 is rotatably connected to the scissor lift frame 3 via bearing rings. Positioning connecting slides 101 are symmetrically arranged on both sides of the upper lifting platform 1, with side support bars 102 arranged in an array at intervals on both sides of the positioning connecting slides 101. The side support bars 102 are slidably connected to the slide grooves of the upper lifting platform 1, forming a grid support surface to meet the movement requirements of the storage trolley's pulleys. Side tightening screws 103 are threadedly connected to the side of the upper lifting platform 1, and the side tightening screws 103 are in tight contact with the positioning connecting slides 101. The side positioning frames 2 can slide synchronously with the positioning connecting slides 101, achieving continuous adjustment of the positioning spacing to adapt to stamping end effector storage trolleys of different lengths.

[0020] In this embodiment of the present disclosure, a lower support frame 201 is fixedly connected to the lower part of the side positioning frame 2, and a lower connecting spring 202 is fixedly connected to the first end of the lower support frame 201.

[0021] In this embodiment, the upper end of the lower connecting spring 202 is fixedly connected to the upper lifting platform 1, the side positioning frame 2 and the positioning connecting slide 101 are slidably connected in the vertical direction, and the lower support frame 201 is located below the upper lifting platform 1. When the scissor lift platform 3 rises, the lower support slide 301 and the lower base 303 separate, and the lower support slide 301, the lower support frame 201 and the side positioning frame 2 move down synchronously. The pulley of the end effector trolley falls into the groove formed by the downward movement of the side positioning frame 2 in the positioning connecting slide 101, effectively limiting the forward and backward and left and right displacement of the storage trolley during the lifting and turning process.

[0022] In this embodiment, the scissor lift platform 3 has symmetrically arranged lower support slides 301 on both sides, and a central drive motor 302 is fixedly connected to the center of the scissor lift platform 3. The scissor lift platform 3 is located inside the lower base 303, and the lower ends of the scissor frames on both sides of the scissor lift platform 3 are slidably connected to the lower base 303. The scissor lift platform 3 and the existing lifting frame structure are the same, and the lifting operation is achieved by expanding and retracting the scissor frames on both sides in conjunction with the extension and retraction of the hydraulic telescopic rod.

[0023] In this embodiment, the lower support slide 301 is located below the lower support frame 201, and the rotating shaft of the middle drive motor 302 is fixedly connected to the center of the upper lifting platform 1. The middle drive motor 302 drives the upper lifting platform 1 to rotate, thereby realizing the horizontal adjustment of the upper lifting platform 1 to match the docking requirements of storage trolleys with different orientations and placement angles.

[0024] In this embodiment, when the scissor lift platform 3 is in its lowest state, the top surface of the upper lifting platform 1 and the top surface of the lower base 303 are flush, and the top of the lower support slide 301 and the bottom of the lower support frame 201 are in contact.

[0025] In this embodiment, when the top of the lower support slide 301 and the bottom of the lower support frame 201 are in contact, the top of the side positioning frame 2 and the top of the positioning connecting slide 101 remain flush and locked. The side positioning frame 2, the positioning connecting slide 101, and the upper lifting platform 1 are flush to form a complete and flat bearing plane. This plane can achieve seamless docking between the storage trolley and the lifting platform. The storage trolley can smoothly enter and exit the lifting platform along the plane without steps or jamming, and without the need for manual lifting or auxiliary pushing.

[0026] In this second embodiment, based on the first embodiment, the scissor lift platform 3 controls a locking bar via an electromagnet. The electromagnet extends the supporting locking bar and engages with the upper lifting platform 1 to achieve the limiting function of the upper lifting platform 1, thereby improving the stability of the storage trolley during movement. When the upper lifting platform 1 rotates, the electromagnet shortens the supporting locking bar and separates from the upper lifting platform 1.

[0027] The working principle of this embodiment is as follows: When the scissor lift platform 3 and the upper lifting platform 1 descend to the lowest working position, the lower support slide 301 first moves into contact with the top of the lower base 303, and the lower support slide 301 cannot continue to move down. When the scissor lift platform 3, the side positioning frame 2, and the upper lifting platform 1 continue to move down, the lower support slide 301 will block the lower support frame 201 and cannot move down. The stationary lower support frame 201 moves up relative to the side positioning frame 2 which continues to descend. The lower support frame 201 and the side positioning frame 2 rise synchronously until they are completely flush with the top of the positioning connecting slide 101, so that the side positioning frame 2, the positioning connecting slide 101, and the upper lifting platform 1 are flush and form a complete and flat bearing plane, and form a locked state. This plane can realize the seamless docking of the storage trolley and the lifting platform. The storage trolley can smoothly enter and exit the lifting platform along the plane without steps or jamming. The entry and exit process does not require manual lifting or auxiliary pushing, which significantly improves the convenience of operation and shortens the docking time of a single storage trolley. The positioning structure of the side positioning frame 2 is aligned with the pulley of the stamping end-effector storage trolley. When the scissor lift platform 3 rises, the lower support slide 301 and the lower base 303 separate. The lower support slide 301, the lower support frame 201 and the side positioning frame 2 move down synchronously. The pulley of the end-effector trolley falls into the groove formed by the downward movement of the side positioning frame 2 in the positioning connecting slide 101. This effectively restricts the forward and backward and left and right displacement of the storage trolley during lifting and turning, and improves the stability and safety of the transfer. The upper lifting platform 1 and the stamping end-collector storage trolley rotate synchronously in a circumferential direction to match the docking requirements of storage trolleys with different orientations and placement angles. There is no need for manual pushing of the storage trolley to adjust its direction, which improves the adaptability of the device to multiple layout scenarios of the automated warehouse and enhances compatibility. The side positioning frame 2 can slide synchronously with the positioning connecting slide 101 to achieve continuous adjustment of the positioning distance. It can adapt to stamping end-collector storage trolleys of different lengths and specifications. There is no need to replace parts. One device can meet the lifting and transfer needs of multiple models of storage trolleys in the workshop, which significantly improves the equipment's versatility.
