Description

Technical Field

[0001] This utility model relates to the field of battery casing injection molding technology, and in particular to an injection molding robot used in the battery casing injection molding industry. Background Technology

[0002] In the field of battery casing manufacturing, injection molding technology has become the mainstream process for manufacturing battery casings due to its rapid prototyping, high efficiency, and high precision. As an important component of batteries, battery casings not only need to meet shape and size requirements, but also need to have high precision, high strength, and good sealing performance to ensure battery safety and service life. In recent years, with the rapid development of new energy vehicles and energy storage equipment, the demand for battery casings has increased significantly, and the requirements for injection molding processes have become increasingly stringent. Currently, the injection molding industry is developing towards intelligence and automation to improve production efficiency and product quality. For example, injection molding robots have been widely used in production lines, significantly improving the automation level of production lines.

[0003] In existing technologies, battery casings are prone to slipping during clamping, causing them to fall off and interrupting the production process, thus reducing production efficiency. Furthermore, battery casings must be placed in the correct orientation when entering the gripper area; if the initial orientation is incorrect, the entire processing flow will be interrupted. Therefore, this paper proposes an injection molding robot for the battery casing injection molding industry to solve the above-mentioned problems. Utility Model Content

[0004] To address the technical problems in existing technologies, such as battery casings easily slipping during clamping, causing them to fall off and interrupting the production process, and the battery casings needing to be placed in the correct orientation when entering the gripper area, which can lead to the interruption of the entire processing if the initial orientation is incorrect, this application provides an injection molding robot for the battery casing injection molding industry.

[0005] This utility model proposes an injection molding robot for the battery casing injection molding industry, comprising a frame, with a rotating device inside the frame, the rotating device including a detection sensor, the detection sensor determining the placement direction of the battery casing through a high-speed camera and combined with an image processing algorithm.

[0006] The lower surface of the frame is provided with a clamping device, which includes a clamping block. The movement of the clamping block clamps the battery casing.

[0007] Preferably, the rotating device further includes a motor, which is fixedly installed on the inner wall of the frame. The output shaft of the motor is rotatably connected to the inner wall of the frame through a bearing seat, and bolt holes are provided on the upper surface of the frame.

[0008] The above technical solution involves fixing the motor to the frame. The motor's output shaft is rotatably connected to the frame via a bearing housing, ensuring the stability of the motor's output shaft rotation. The frame can be made of aluminum alloy, and the motor can be a servo motor equipped with a driver and encoder. The specific model can be selected according to actual needs. Bolt holes are provided on the frame for mounting a robotic arm. This robotic arm can be mounted on the Z-axis slide of the ZYAM-Y2Z2-1401 gantry motion platform, driving the robotic arm to move along the X, Y, and Z axes. The Z-axis platform of this model is responsible for vertical movement, the X-axis platform assists in horizontal movement, and the Y-axis platform handles complex forward and backward movement. In practical applications, the model of the gantry motion platform can be selected separately according to actual needs.

[0009] Preferably, the output shaft of the motor is fixedly mounted with a rotating frame, the rotating frame is rotatably connected to the groove on the lower surface of the frame via a bearing, and the detection sensor is fixedly mounted on the lower surface of the rotating frame.

[0010] The above technical solution involves fixing the output shaft of a motor to a rotating frame, driving the rotating frame to rotate. The rotating frame is connected to the frame via bearings to ensure its rotational stability. A detection sensor is fixedly installed to the rotating frame for stability. The rotating frame is also made of aluminum alloy. The detection sensor can be an industrial camera, such as the Checker / In-Sight series. The resolution is selected based on the size of the battery case and the required detection accuracy. The frame rate needs to be high enough to capture rapidly changing scenes. A suitable lens and appropriate light source are required to obtain the best image contrast and clarity. At the same time, mature machine vision software libraries such as HALCON are used, and existing image processing programs are configured to identify the orientation of the battery case.

[0011] Preferably, the clamping device further includes an electric push rod, which is fixedly installed on the inner wall of the rotating frame, and a slider is fixedly installed at one end of the telescopic rod of the electric push rod.

[0012] The above technical solution involves fixing the electric push rod to the rotating frame, rotating the frame, and fixing the electric push rod to the slider. The extension and retraction of the electric push rod causes the slider to rise and fall, thereby moving the clamping block that is slidably connected to it.

[0013] Preferably, the clamping block is slidably inserted into the groove on the lower surface of the rotating frame, and the outer side of the slider is slidably connected to the outer side of the clamping block.

[0014] The above technical solution uses a sliding connection between the clamping block and the rotating frame to fix the battery case without affecting its movement. The sliding connection between the slider and the clamping block allows the clamping block to move in the opposite direction as the slider descends, thereby releasing the clamping and fixing of the battery case. Both the clamping block and the slider are made of aluminum alloy and have been lubricated to reduce friction and wear on the contact surfaces, thus extending the service life of the components.

[0015] Preferably, a stainless steel spring is fixedly installed on one side of the clamping block, the stainless steel spring is fixedly installed on the inner side wall of the rotating frame, and a silicone layer is fixedly adhered to the outer side of the clamping block.

[0016] With the above technical solution, stainless steel springs are fixedly installed to the clamping blocks and the rotating frame respectively. When the slider rises, the compressed stainless steel springs cause the clamping blocks to return to their original position, thereby causing the two clamping blocks to move relative to each other and clamp the battery case. The clamping blocks are fixedly bonded to the silicone layer, which not only fixes the battery case but also facilitates replacement. The silicone layer contacts the battery case, which increases the clamping force while avoiding damage to the surface of the battery case.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By setting up a rotating device, the placement direction of the battery case is determined. Bolt holes are opened on the frame to allow the robot arm to be installed. The motor drives the rotating frame to rotate. The detection sensor needs to be used with a suitable lens and a suitable light source to obtain the best image contrast and clarity. At the same time, mature machine vision software libraries such as HALCON are used to configure the existing image processing program to identify the orientation of the battery case. This solves the technical problem in the prior art that the battery case must be placed in the correct orientation when entering the robot arm's gripping area. If the initial placement orientation is incorrect, the entire processing flow will be interrupted.

[0019] 2. By setting up a clamping device, the battery casing is clamped. The extension and retraction of the electric push rod drives the slider to rise and fall. When the slider rises, the compressed stainless steel spring resets the clamping blocks, thereby causing the two clamping blocks to move relative to each other and clamp the battery casing. The clamping blocks are fixedly bonded to the silicone layer, and the silicone layer contacts the battery casing, which increases the clamping force while avoiding damage to the surface of the battery casing. When the slider falls, it drives the clamping blocks to move in the opposite direction, thereby releasing the clamping fixation of the battery casing. This solves the technical problem in the prior art where the battery casing is easy to slip during clamping, causing it to fall off during the clamping process, thus interrupting the production process and reducing production efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A robotic arm for use in the battery casing injection molding industry includes a frame 1 with a rotating device inside. The rotating device includes a detection sensor 31, which uses a high-speed camera and an image processing algorithm to determine the placement direction of the battery casing.

[0028] To ensure the stability of the output shaft rotation of motor 2, the rotating device also includes motor 2. Motor 2 is fixedly installed on the inner wall of frame 1. The output shaft of motor 2 is rotatably connected to the inner wall of frame 1 through a bearing seat. Bolt holes 21 are provided on the upper surface of frame 1. Motor 2 is fixedly installed to frame 1, and the output shaft of motor 2 is rotatably connected to frame 1 through a bearing seat to ensure the stability of the output shaft rotation of motor 2. The material of frame 1 can be aluminum alloy. Motor 2 can be a servo motor 2 equipped with a driver and encoder. The specific model can be selected according to actual needs. Bolt holes 21 are provided on frame 1 to install a robot arm. The robot arm can be installed on the Z-axis slide of the gantry motion platform of model ZYAM-Y2Z2-1401 of Zhongyan Yingchuang, driving the robot arm to move in three axes of X, Y and Z. The Z-axis platform of this model is responsible for vertical movement, the X-axis platform assists in horizontal movement, and the Y-axis platform is responsible for complex forward and backward movement. In actual applications, the model of gantry motion platform can be selected separately according to actual needs.

[0029] To identify the orientation of the battery case, a rotating frame 3 is fixedly mounted on the output shaft of motor 2. The rotating frame 3 is rotatably connected to the groove on the lower surface of frame 1 via a bearing. A detection sensor 31 is fixedly mounted on the lower surface of the rotating frame 3, and is also fixedly mounted to the rotating frame 3 via the output shaft of motor 2, driving the rotating frame 3 to rotate. The rotating frame 3 is rotatably connected to frame 1 via a bearing to ensure its rotational stability. The detection sensor 31 is fixedly mounted to the rotating frame 3 for fixation. The rotating frame 3 is also made of aluminum alloy. The detection sensor 31 can be an industrial camera, such as the Checker / In-Sight series. The resolution is selected according to the size of the battery case and the detection accuracy requirements. The frame rate needs to be high enough to capture rapidly changing scenes. It needs to be paired with a suitable lens and equipped with a suitable light source to obtain the best image contrast and clarity. At the same time, mature machine vision software libraries such as HALCON are used, and existing image processing programs are configured to identify the orientation of the battery case.

[0030] By setting up a rotating device to determine the placement direction of the battery case, bolt holes 21 are provided on the frame 1 to allow the robot arm to be installed via bolts. The motor 2 drives the rotating frame 3 to rotate. The detection sensor 31 needs to be paired with a suitable lens and equipped with a suitable light source to obtain the best image contrast and clarity. At the same time, mature machine vision software libraries such as HALCON are used to configure existing image processing programs to identify the orientation of the battery case. This solves the technical problem in the prior art that the battery case must be placed in the correct orientation when entering the gripping area of ​​the robot arm. If the initial placement orientation is incorrect, it will cause the entire processing flow to be interrupted.

[0031] In order to clamp the battery case, a clamping device is provided on the lower surface of the frame 1. The clamping device includes a clamping block 5, and the movement of the clamping block 5 clamps the battery case.

[0032] In order to move the clamping block 5, the clamping device also includes an electric push rod 4. The electric push rod 4 is fixedly installed on the inner wall of the rotating frame 3. A slider 41 is fixedly installed at one end of the telescopic rod of the electric push rod 4. The electric push rod 4 is fixedly installed with the rotating frame 3 and is fixed thereto. The rotating frame 3 drives the rotating block 5 to rotate. The telescopic rod of the electric push rod 4 is fixedly installed with the slider 41. The extension and retraction of the telescopic rod drives the slider 41 to rise and fall, thereby driving the clamping block 5, which is slidably connected to it, to move.

[0033] To release the clamping and fixing of the battery case, the clamping block 5 is slidably inserted into the groove on the lower surface of the rotating frame 3. The outer side of the slider 41 is slidably connected to the outer side of the clamping block 5. By sliding the clamping block 5 into the rotating frame 3, it is fixed without affecting its movement. By sliding the slider 41 into the clamping block 5, the descent of the slider 41 can drive the clamping block 5 to move in the opposite direction, thereby releasing the clamping and fixing of the battery case. The clamping block 5 and the slider 41 are both made of aluminum alloy and are lubricated on the surface to reduce friction and effectively reduce wear on the contact surfaces, thereby extending the service life of the components.

[0034] To avoid damage to the battery casing surface, a stainless steel spring 6 is fixedly installed on one side of the clamping block 5. The stainless steel spring 6 is fixedly installed on the inner wall of the rotating frame 3, and a silicone layer 61 is fixedly bonded to the outer side of the clamping block 5. The stainless steel spring 6 is fixedly installed to the clamping block 5 and the rotating frame 3 respectively. When the slider 41 rises, the compressed stainless steel spring 6 causes the clamping block 5 to return to its original position, thereby causing the two clamping blocks 5 to move relative to each other and clamp the battery casing. The clamping block 5 is fixedly bonded to the silicone layer 61, which not only fixes it but also facilitates replacement. The silicone layer 61 contacts the battery casing, which improves the clamping force while avoiding damage to the surface of the battery casing.

[0035] By setting up a clamping device, the battery casing is clamped. The extension and retraction of the telescopic rod of the electric push rod 4 drives the slider 41 to rise and fall. When the slider 41 rises, the compressed stainless steel spring 6 resets the clamping block 5, thereby causing the two clamping blocks 5 to move relative to each other and clamp the battery casing. The clamping block 5 is fixedly bonded to the silicone layer 61, and the silicone layer 61 contacts the battery casing, which improves the clamping force while avoiding damage to the surface of the battery casing. The descent of the slider 41 drives the clamping block 5 to move in the opposite direction, thereby releasing the clamping and fixing of the battery casing. This solves the technical problem in the prior art that the battery casing is easy to slip during clamping, causing it to fall off during the clamping process, thereby interrupting the production process and reducing production efficiency.

[0036] Working principle: When the injection molding robot is needed, the operator installs the frame 1 on the Z-axis slide of the ZYAM-Y2Z2-1401 platform through the bolt holes 21 on the frame 1. The controller of the gantry platform communicates with the controller of the frame 1 through Ethernet. The movement of the frame 1 is controlled by the coordinated movement of the X, Y and Z axes of the gantry platform.

[0037] When it is necessary to adjust the gripping direction of the battery case, the detection sensor 31 captures an image of the battery case, and through visual algorithm processing, determines the directional deviation of the battery case. The directional information is then sent to the controller of the frame 1. Based on the visual information, the controller controls the motor 2 to drive the rotating frame 3 to rotate by a specified angle through the program. Subsequently, the controller of the gantry platform controls the Z-axis slide to descend through the program.

[0038] When the clamping block 5 approaches the battery case, the controller of frame 1 controls the telescopic rod of the electric push rod 4 inside the rotating frame 3 to retract, causing the slider 41 to rise. At this time, under the restoring force of the stainless steel spring 6, the clamping blocks 5 slidably inserted on the rotating frame 3 move towards each other to clamp the battery case. The silicone layer 61 on the clamping block 5 contacts the battery case, increasing the clamping force while avoiding damage to the surface of the battery case. After the battery case is clamped, the frame 1 holding the battery case is moved to the next station by the coordinated movement of the X, Y, and Z axes of the gantry platform. The controller of frame 1 controls the telescopic rod of the electric push rod 4 to extend, causing the slider 41 to descend and squeeze the clamping block 5, causing it to move in the opposite direction, thereby releasing the battery case. Then, the frame 1 is controlled to return to the starting position or the next standby position to prepare to grab the next battery case.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
