Description

Technical Field

[0001] This utility model relates to the field of battery positioning mold technology, specifically to a trolley positioning device. Background Technology

[0002] With the increasing popularity of new energy vehicles, batteries are being used more frequently. During automotive manufacturing, batteries need to be handled multiple times. Currently, robotic arms are used to replace traditional manual handling to improve efficiency and reduce the risk of accidents. Batteries are typically first moved from the warehouse by forklifts, then the robotic arms transfer them one by one to transport trolleys. The transport trolleys must be securely fixed before receiving batteries to prevent the robotic arms from failing to place the batteries accurately in their designated positions along a pre-set path after the trolley has slid.

[0003] Currently, after the transport trolley reaches the target location, it is usually braked with its foot brake to secure it. However, during the battery receiving process, the transport trolley is prone to slipping relative to the ground under the weight of the battery, causing the robotic arm to be unable to place the battery stably at the target location on the transport trolley according to the preset path. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a trolley positioning device to solve the technical problem that in the prior art, the trolley is usually fixed by its own foot brake, and the trolley is prone to slipping relative to the ground under the gravity of the battery during the battery receiving process, which makes it impossible for the robot arm to place the battery stably in the target position of the trolley according to the preset path.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a trolley positioning device, comprising: Fixture; The lifting assembly is slidably connected to the fixed frame along a first direction, wherein the first direction is the direction of lifting relative to the fixed frame; and The driving assembly includes a driving member and a force-applying member. The force-applying member is slidably connected to the fixed frame along a second direction and has an inclined force-applying surface. The second direction is set at an angle to the first direction. The driving member is disposed on the fixed frame and connected to the force-applying member. The driving member can drive the force-applying member to slide along the second direction, so that the force-applying surface drives the lifting assembly to slide along the first direction.

[0006] In some embodiments, the force-applying member has a first limiting flange located at the lowest point of the force-applying surface, for limiting excessive descent of the lifting assembly.

[0007] In some embodiments, the force-applying member has a horizontal surface and a second limiting flange, one end of the horizontal surface is connected to the highest point of the force-applying surface, and the other end of the horizontal surface is connected to the second limiting flange, which protrudes from the horizontal surface.

[0008] In some embodiments, the driving member includes a driving cylinder, a telescopic rod, and a connecting rod connected in sequence, the connecting rod being connected to the force-applying member.

[0009] In some embodiments, the force-applying member has multiple components, each of which is connected to the driving member. The driving member can drive the multiple force-applying members to press against the lifting assembly along the second direction, thereby driving the lifting assembly to slide along the first direction.

[0010] In some embodiments, the lifting assembly includes a lifting platform and a positioning pin connected together, the positioning pin protruding from the surface of the lifting platform, the lifting platform being slidably connected to the fixed frame along the first direction, and the positioning pin being able to insert a trolley when the lifting platform rises.

[0011] In some embodiments, the lifting assembly further includes a passive roller, which is rotatably disposed on the lifting platform. When the force-applying member slides along the second direction, it can press against the passive roller through the force-applying surface and drive the lifting platform to rise through the passive roller.

[0012] In some embodiments, the lifting assembly further includes a plurality of guide wheels, which are spaced apart and rotatably disposed on the lifting platform along the length extension direction of the fixed frame.

[0013] In some embodiments, the trolley positioning device further includes an auxiliary fixing component disposed on the fixed frame, the auxiliary fixing component being used to clamp and fix the moving trolley lifted by the lifting component.

[0014] In some embodiments, the auxiliary fixing assembly includes an auxiliary cylinder, a first clamp, a second clamp, and a linkage rod. The first clamp and the second clamp are both rotatably connected to the fixing frame. The auxiliary cylinder is disposed on the fixing frame and connected to the first clamp. The two ends of the linkage rod are rotatably connected to the first clamp and the second clamp.

[0015] Compared with the prior art, the trolley positioning device provided by this utility model has a lifting component that slides along a first direction, which can be considered as a vertical direction. The trolley can first travel above the lifting component, and then the driving component drives the force-applying component to slide along a second direction, which can be considered as a horizontal direction. The force-applying component presses against the lifting component through an inclined force-applying surface to drive the lifting component to rise, thereby lifting the trolley to lift it off the ground. The trolley is then fixed, and the robotic arm can place the battery on the trolley without causing it to shift, ensuring stable operation. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the technical problem in existing technologies where transport trolleys are typically fixed by their own foot brakes, causing them to slip relative to the ground under the weight of the batteries during battery reception, thus preventing the robotic arm from smoothly placing the batteries at the target position on the trolley according to the preset path, this invention provides a trolley positioning device. This device can lift and fix the transport trolley, allowing it to detach from the ground and preventing it from shifting during battery reception, thus ensuring stable operation.

[0019] It should be noted that the trolley positioning device described in this utility model is used for, but not limited to, positioning of transport trolleys. For ease of explanation, this utility model only uses the application of the trolley positioning device to transport trolleys as an example. The principle of the trolley positioning device applied to other types of equipment is essentially the same as that applied to transport trolleys, and will not be described in detail here.

[0020] Please see Figures 1 to 4 , Figure 1This is a schematic diagram of the structure of a trolley positioning device in one embodiment of the present invention. The trolley positioning device 100 includes a fixed frame 1, a lifting assembly 2, and a drive assembly 3. The lifting assembly 2 is slidably connected to the fixed frame 1 along a first direction. The drive assembly 3 includes a driving member 31 and a force-applying member 32. The force-applying member 32 is slidably connected to the fixed frame 1 along a second direction and has an inclined force-applying surface 321. The second direction forms a certain angle with the first direction. The driving member 31 is disposed on the fixed frame 1 and connected to the force-applying member 32, and can drive the force-applying member 32 to slide along the second direction, pressing the lifting assembly 2 against the force-applying surface 321, causing it to slide along the first direction.

[0021] In this embodiment, the first direction can be vertical, the second direction can be horizontal, and the first and second directions can be perpendicular to each other if they form an angle. The sliding of the lifting assembly 2 along the first direction can be understood as lifting relative to the fixed frame 1, and the sliding of the force-applying component 32 along the second direction can be understood as horizontal sliding. The inclination angle of the force-applying surface 321 is not limited, for example... Figure 1 In the illustrated embodiment, the tilt angle is 45°. When the driving member 31 drives the force-applying member 32 to slide horizontally, the force-applying member 32 presses against the lifting assembly 2 through its tilted force-applying surface 321, thereby driving the lifting assembly 2 to rise. The transport trolley 5 can be moved to a preset position in advance so that the side of the transport trolley 5 is directly above the lifting assembly 2. When the lifting assembly 2 rises, it can lift the transport trolley 5 and raise it so that the transport trolley 5 is off the ground. The transport trolley 5 will not deviate when receiving batteries transferred by the robotic arm. The robotic arm can place multiple batteries one by one into the transport trolley 5 according to a preset path.

[0022] Please see Figure 2 The trolley positioning device 100 of this application can be provided in two, with the two trolley positioning devices 100 arranged at intervals, forming a receiving space between them for the transport trolley 5 to enter. When the transport trolley 5 moves into the receiving space, the two sides of the transport trolley 5 are respectively located directly above the two lifting components 2. Then, the two driving components 31 are controlled to simultaneously drive the two lifting components 2 to rise, so that the two lifting components 2 lift the transport trolley 5 together and drive the transport trolley 5 to leave the ground.

[0023] In one embodiment, please refer to Figure 4The lifting assembly 2 includes a lifting platform 21 and a positioning pin seat 22. The positioning pin seat 22 protrudes from the surface of the lifting platform 21 and can be inserted into the side bottom surface of the moving trolley when the lifting platform 21 rises, thereby achieving positioning and fixing of the moving trolley. Slide rails 23 are provided on both sides of the lifting platform 21, arranged along a first direction (vertical direction). The lifting platform 21 is slidably connected to the slide rails 23 via a sliding groove, ensuring stable lifting and lowering of the lifting platform 21. In this embodiment, the positioning pin seat 22 is inserted into the transport trolley 5, further fixing the transport trolley 5 when it is lifted by the lifting platform 21, thus improving the positioning stability of the transport trolley 5.

[0024] In one embodiment, please refer to Figure 4 The lifting assembly 2 also includes a passive roller 24, which is rotatably mounted on the bottom of the lifting platform 21. When the force-applying member 32 slides along the second direction (horizontal direction), its force-applying surface 321 can press against the passive roller 24, driving the lifting platform 21 to rise through the passive roller 24, while the passive roller 24 is also rotating. In this embodiment, the rolling friction of the passive roller 24 reduces the force required for driving, making the rise of the lifting platform 21 smoother.

[0025] In one embodiment, please refer to Figure 4 The force-applying component 32 has a first limiting flange 322, which is located at the lowest point of the force-applying surface 321 and is used to limit the excessive descent of the lifting assembly 2. In this embodiment, by setting the first limiting flange 322, the force-applying component 32 can be limited, preventing it from sliding excessively and deviating from the track. At the same time, the first limiting flange 322 can also play a positioning role; when the passive roller 24 abuts against the first limiting flange 322, the lifting platform 21 is in its lowest position.

[0026] In one embodiment, please refer to Figure 4 The force-applying component 32 has a horizontal surface 323 and a second limiting flange 324. One end of the horizontal surface 323 is connected to the highest point of the force-applying surface 321, and the other end is connected to the second limiting flange 324, which protrudes from the horizontal surface 323. As the force-applying component 32 moves horizontally, the passive roller 24 rolls obliquely upward along the force-applying surface 321. After passing the force-applying surface 321, the passive roller 24 rolls to the horizontal surface 323. At this time, the lifting platform 21 is at its highest point, lifting the transport trolley 5 to its highest position. The horizontal surface 323 mainly provides a stable support for the lifting platform 21 so that the lifting platform 21 can remain stable when lifting the transport trolley 5 to its highest position. The second limiting flange 324 is used to limit the force-applying component 32 to prevent it from sliding excessively and disengaging from the passive roller 24.

[0027] In one embodiment, please refer to Figure 4The driving component 31 includes a driving cylinder 311, a telescopic rod 312, and a connecting rod 313 connected in sequence. The connecting rod 313 is connected to the force-applying component 32. The driving cylinder 311, through the telescopic movement of the telescopic rod 312, can drive the force-applying component 32 to slide along the second direction (horizontal direction). When the force-applying component 32 slides along... Figure 3 When the force-applying component 32 slides to the left, it can drive the lifting platform 21 to rise; when the force-applying component 32 slides along the left, it can drive the lifting platform 21 to rise. Figure 3 When the slide is to the right, the force-applying component 32 can drive the lifting platform 21 to descend. In other embodiments, a servo motor can be used instead of the drive cylinder 311, and a lead screw can be used instead of the telescopic rod. The lead screw is threaded to the force-applying component 32, and the servo motor drives the lead screw to rotate. The lead screw drives the force-applying component 32 to reciprocate through the threaded engagement.

[0028] In one embodiment, please refer to Figure 4 The force-applying component 32 has multiple components, and all of the force-applying components 32 are connected to the drive component 31. The drive component 31 can simultaneously drive multiple force-applying components 32 to slide along the second direction, and press against different positions of the lifting assembly 2 through their respective force-applying surfaces 321, so as to ensure that the lifting platform 21 is evenly stressed and rises stably. Figure 3 In the illustrated embodiment, there are two force-applying components 32, which are arranged at intervals and connected by a connecting rod 313 to achieve synchronous sliding. When sliding, the two force-applying components 32 can simultaneously drive the lifting platform 21 to rise and fall. The two force-applying components 32 act on different parts of the lifting platform 21 to provide stability for the lifting platform 21 during its rise and fall.

[0029] In one embodiment, please refer to Figure 2 The lifting assembly 2 also includes multiple guide wheels 25, which are rotatably disposed on the side of the fixed frame 1 along the length of the lifting platform 21. During the process of the transport trolley 5 entering the receiving space, the side of the transport trolley 5 contacts the guide wheels 25, which guide the transport trolley 5, allowing it to smoothly and quickly enter the receiving space and reach the designated position, thus improving work efficiency. Furthermore, the guide wheels 25 protrude from the side of the fixed frame 1, preventing the transport trolley 5 from colliding with the fixed frame 1.

[0030] In one embodiment, please refer to Figure 2 and Figure 3 The trolley positioning device also includes an auxiliary fixing component 4, which is located on the fixing frame 1 and is used to clamp and fix the moving trolley lifted by the lifting component 2. When the transport trolley 5 is lifted by the lifting platform 21, the auxiliary fixing component 4 starts to work again to clamp the side of the transport trolley 5, thereby further fixing the transport trolley 5 and keeping it fixed when receiving the battery.

[0031] Further, please refer to Figure 3 The auxiliary fixing component 4 includes an auxiliary cylinder 41, a first clamp 42, a second clamp 43, and a linkage rod 44. Both the first clamp 42 and the second clamp 43 are rotatably connected to the fixing frame 1. The auxiliary cylinder 41 is located on the fixing frame 1 and connected to the first clamp 42. The two ends of the linkage rod 44 are rotatably connected to the first clamp 42 and the second clamp 43. When the auxiliary cylinder 41 is activated, it drives the first clamp 42 to rotate. Through the transmission of the linkage rod 44, the first clamp 42 drives the second clamp 43 to rotate, so that the first clamp 42 and the second clamp 43 simultaneously clamp or release the transport trolley 5, providing additional fixing force to the transport trolley 5 and ensuring that the moving trolley remains absolutely fixed during battery reception.

[0032] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: The trolley positioning device provided by this utility model has a lifting component that slides along a first direction, which can be considered as a vertical direction. The trolley can first travel above the lifting component, and then the driving component drives the force-applying component to slide along a second direction, which can be considered as a horizontal direction. The force-applying component presses against the lifting component through an inclined force-applying surface, thereby driving the lifting component to rise. Thus, the lifting component lifts the trolley to lift it off the ground, and the trolley is fixed. The robotic arm places the battery on the trolley without causing the trolley to shift, ensuring stable operation.

Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
