Description

Technical Field

[0001] This invention relates to the field of CCD inspection technology, specifically to a translational entry and exit inspection device. Background Technology

[0002] In the manufacturing process of new energy battery boxes, product inspection is an essential step. Manual inspection is the most traditional method, simple in style but lacking in clarity and consistency, and it compromises sample quality. Furthermore, manual inspection is extremely labor-intensive. CCD vision inspection technology can overcome these drawbacks. Existing CCD inspection equipment involves transporting the product to the inspection area and using an industrial camera for image analysis. Because the camera's position is fixed, precise transport of the battery box to the inspection station is crucial for comprehensive image analysis. However, current technology requires manual handling of the battery box onto the conveyor table. The battery box's weight makes handling laborious, and placing it on the conveyor table makes precise control of its angle and position impossible, leading to camera errors. Summary of the Invention

[0003] To address the aforementioned issues, it is necessary to provide a translational entry / exit inspection device that addresses the problems of existing technologies.

[0004] To address the existing technical problems, the present invention adopts the following technical solution: a translational in-and-out testing device, comprising a loading cabinet, a testing cabinet, and two parallel conveying tracks extending from the loading cabinet into the testing cabinet. A loading trolley is positioned between the two conveying tracks in the loading cabinet. A mobile platform is slidably mounted on the conveying tracks. A traveling unit is mounted on the mobile platform to drive the mobile platform to move along the conveying tracks. A lifting platform is slidably mounted on the mobile platform, along with a linear drive to drive the lifting platform to move vertically. Several contact rollers and support feet are provided on opposite sides of the two lifting platforms. The contact rollers contact the sides of the battery box on the loading trolley to correct the orientation of the battery box. The support feet are located below the sides of the battery box on the loading trolley.

[0005] Preferably, a rack is fixedly installed on the conveying track, the rack extends along the length of the conveying track, and the traveling unit includes a rotary driver fixedly installed on the moving platform. The rotary driver's rotation shaft is vertically arranged, and a gear is coaxially installed on the working end of the rotary driver. The gear meshes with the rack.

[0006] Preferably, the lifting platform is provided with several vertical mounting frames, which are evenly distributed along the length of the conveying track. The rollers are mounted on the top of the mounting frames, and the rotation axis of the rollers is vertically set.

[0007] Preferably, the mobile platform is provided with a plurality of vertical linear slide rails, on which sliders are slidably mounted. A lifting platform is fixedly mounted on the sliders, and a linear driver is fixedly mounted on the mobile platform. The working end of the linear driver is set to move in the vertical direction and is fixedly connected to the lifting platform.

[0008] Preferably, the feeding cabinet has guide plates on both sides at the end away from the testing cabinet, forming an outwardly expanding opening between the guide plates. Several adjusting rollers are rotatably mounted on the guide plates, and the adjusting rollers are evenly distributed along the length of the guide plates. The axis of the adjusting rollers is parallel to the axis of the contact roller.

[0009] Preferably, a limit baffle is provided at one end of the loading cabinet near the testing cabinet. The limit baffle extends in a horizontal direction perpendicular to the conveying track and is provided with at least two positioning rollers. The height of the positioning rollers is higher than the upper surface of the loading trolley.

[0010] The advantages of this invention compared to the prior art are: Firstly, in this embodiment, the battery box on the loading trolley is automatically lifted and moved into the testing cabinet by the support legs on the lifting platform of the mobile platform. After the testing is completed, it is automatically reset to the loading trolley, eliminating the need for manual handling of the battery box and saving a lot of manpower.

[0011] Secondly, in this embodiment, the initial position of the battery box at the loading cabinet is fixed by positioning rollers, and the direction of the battery box is corrected by the fitting rollers. This ensures that the battery box is in the same position when it reaches the inspection station after each time the moving platform transports the battery box into the inspection cabinet. This ensures that the effect of the vision camera is consistent each time, which is convenient for comparison with the data to judge the inspection results. Attached Figure Description

[0014] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figures 1 to 5 : A translational in-and-out testing device includes a loading cabinet 1, a testing cabinet 2, and two parallel conveying tracks 3 extending from the loading cabinet 1 into the testing cabinet 2. A loading trolley 1a is located between the two conveying tracks 3 in the loading cabinet 1. A mobile platform 4 is slidably mounted on the conveying tracks 3. A walking unit 4a is provided on the mobile platform 4 for driving the mobile platform 4 to move along the conveying tracks 3. A lifting platform 4b is slidably mounted on the mobile platform 4, and a linear drive 4c is provided for driving the lifting platform 4b to move vertically. Several contact rollers 4b1 and support feet 4b2 are provided on opposite sides of the two lifting platforms 4b. The contact rollers 4b1 contact the sides of the battery box on the loading trolley 1a to correct the orientation of the battery box. The support feet 4b2 are located below the sides of the battery box on the loading trolley 1a.

[0016] Before use, the operator adjusts the distance between the contact rollers 4b1 of the two moving platforms 4 on the conveyor track 3 to be the same as the width of the battery box to be tested. During use, the moving platforms 4 on the conveyor track 3 move to the loading cabinet 1 under the drive of the walking unit 4a. The operator pushes the loading trolley 1a carrying the battery box to the loading cabinet 1, positioning it between the two conveyor tracks 3. At this time, the contact rollers 4b1 on the lifting platform 4b of the moving platform 4 contact the sides of the battery box, automatically adjusting the position of the battery box. The support feet 4b2... Located below the battery box, the linear actuator 4c drives the lifting platform 4b to rise, so that the support feet 4b2 contact the bottom of the battery box and lift the battery box. Then, the traveling unit 4a drives the two moving platforms 4 to move along the conveyor track 3 to move the battery box horizontally into the inspection cabinet 2 for visual inspection. After the inspection is completed, the moving platform 4 moves the battery box back to the loading cabinet 1, and the linear actuator 4c drives the lifting platform 4b to move down so that the battery box is placed on the loading trolley 1a again. The operator pushes the loading trolley 1a out of the loading cabinet 1 to complete one inspection. In this embodiment, the battery box on the loading trolley 1a is automatically lifted and moved into the testing cabinet 2 by the support feet 4b2 on the lifting platform 4b of the mobile platform 4. After testing, it is automatically reset to the loading trolley 1a, eliminating the need for manual handling of the battery box and saving a lot of manpower. In this embodiment, the fitting rollers 4b1 on the mobile platform 4 are matched with the width of the battery box. When the staff pushes the loading trolley 1a into the loading cabinet 1, the fitting rollers 4b1 automatically adjust the direction of the battery box on the loading trolley 1a, ensuring that the support feet 4b2 are located below the battery box and can lift the battery box.

[0017] To enable the mobile platform 4 to move along the conveyor track 3, the following features are specifically designed: A rack 3a is fixedly installed on the conveying track 3. The rack 3a extends along the length of the conveying track 3. The walking unit 4a includes a rotary driver 4a1 fixedly installed on the moving platform 4. The rotation shaft of the rotary driver 4a1 is vertically arranged. A gear 4a2 is coaxially installed at the working end of the rotary driver 4a1. The gear 4a2 meshes with the rack 3a.

[0018] In this embodiment, the rotary driver 4a1 can be a servo motor. The walking unit 4a drives the gear 4a2 to rotate through the rotary driver 4a1. The gear 4a2 meshes with the rack 3a on the conveying track 3. Therefore, the rotation of the gear 4a2 is converted into the horizontal movement of the moving platform 4 along the rack 3a. The rotary drivers 4a1 on the two moving platforms 4 start synchronously, which can realize the translation of the battery box.

[0019] To ensure that the support feet 4b2 are located at the bottom of the battery box when the walking unit 4a is in contact with both sides of the battery box, the following features are specifically designed: The lifting platform 4b is provided with several vertical mounting frames 4b3, which are evenly distributed along the length of the conveying track 3. The fitting rollers 4b1 are rotatably mounted on the top of the mounting frames 4b3, and the rotation axis of the fitting rollers 4b1 is vertically set.

[0020] In this embodiment, the bonding roller 4b1 is rotatably mounted on the mounting frame 4b3, keeping the bonding roller 4b1 on the support foot 4b2. When the walking unit 4a drives the moving platform 4 to move to the loading cabinet 1, the lifting platform 4b is at its lowest position. At this time, the height of the support foot 4b2 is lower than the surface of the loading trolley 1a. Since the distance between the bonding rollers 4b1 is the same as the width of the battery box, after the direction of the battery box is adjusted by the bonding rollers 4b1, the direction of the battery box entering the inspection cabinet 2 is the same each time. Since the straight distance between the support feet 4b2 on both sides of the bonding roller 4b1 is less than the straight distance between the two bonding rollers 4b1, it is ensured that the support foot 4b2 can contact the bottom of the battery box after moving upward.

[0021] To improve the stability of the lifting platform 4b when raising the battery box, the following features are specifically designed: The mobile platform 4 is provided with several vertical linear slide rails 4d, and a slider 4d1 is slidably installed on the linear slide rails 4d. The lifting platform 4b is fixedly installed on the slider 4d1, and the linear driver 4c is fixedly installed on the mobile platform 4. The working end of the linear driver 4c is set to move in the vertical direction, and the working end of the linear driver 4c is fixedly connected to the lifting platform 4b.

[0022] In this embodiment, the linear actuator 4c can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc. When the linear actuator 4c pushes the lifting platform 4b to move in the vertical direction, the slider 4d1 connected to the lifting platform 4b moves along the linear slide rail 4d to guide the movement path of the lifting platform 4b, avoid the working end of the linear actuator 4c from bearing radial pressure, and ensure the stability of the lifting platform 4b when lifting the battery box.

[0023] In order to adjust the direction of the battery box on the loading trolley 1a entering the loading cabinet 1, the following features are specifically set: The feeding cabinet 1 is provided with guide plates 1b on both sides of the end away from the detection cabinet 2. The guide plates 1b form an outwardly expanding opening. Several adjusting rollers 1b1 are rotatably installed on the guide plates 1b. The adjusting rollers 1b1 are evenly distributed along the length direction of the guide plates 1b. The axis of the adjusting rollers 1b1 is parallel to the axis of the mating rollers 4b1.

[0024] In this embodiment, when the loading trolley 1a carrying the battery box enters the loading cabinet 1, if the battery box on the loading trolley 1a is biased to one side of the loading trolley 1a, the two sides will first contact the adjusting rollers 1b1 on the guide plate 1b. As the loading trolley 1a moves into the loading cabinet 1, the distance between the adjusting rollers 1b1 gradually decreases. Therefore, the adjusting rollers 1b1 can push the battery box to move to the center of the loading trolley 1a, ensuring that when the loading trolley 1a is fully inside the loading cabinet 1, the contact rollers 4b1 are in contact with both sides of the battery box on the loading trolley 1a.

[0025] To ensure the accuracy of the battery box delivered by the mobile platform 4 and positioned precisely at the inspection location after entering the inspection cabinet 2, the following features were specifically designed: A limit baffle 1c is provided at one end of the loading cabinet 1 near the inspection cabinet 2. The limit baffle 1c extends in a horizontal direction perpendicular to the conveying track 3. At least two positioning rollers 1c1 are provided on the limit baffle 1c. The height of the positioning rollers 1c1 is higher than the upper surface of the loading trolley 1a.

[0026] In this embodiment, the loading trolley 1a moves into the loading cabinet 1 until the battery box on the loading trolley 1a is aligned with the positioning roller 1c1 on the limiting baffle 1c. The positioning roller 1c1 fixes the initial position of the battery box at the loading cabinet 1. Each time the lifting platform 4b on the moving platform 4 lifts the battery box, the battery box can enter the inspection cabinet 2 through the limiting baffle 1c. The battery box is always in the same position on the moving platform 4. With the alignment roller 4b1 correcting the direction of the battery box, it is ensured that the battery box is always in the same position when it reaches the inspection station after the moving platform 4 delivers the battery box into the inspection cabinet 2. This ensures that the effect of the vision camera is consistent each time, which is convenient for comparison with the data to judge the inspection results.

[0027] Working principle: Before use, the operator adjusts the distance between the contact rollers 4b1 of the two moving platforms 4 on the conveyor track 3 to be the same as the width of the battery box to be tested. During use, the moving platforms 4 on the conveyor track 3 move to the loading cabinet 1 under the drive of the walking unit 4a. The operator pushes the loading trolley 1a carrying the battery box to the loading cabinet 1 and positions it between the two conveyor tracks 3. At this time, the contact rollers 4b1 on the lifting platform 4b of the moving platform 4 contact the two sides of the battery box, automatically adjusting the position of the battery box. At this time, the support feet 4b... 2 is located below the battery box. Then, the linear actuator 4c drives the lifting platform 4b to rise, so that the support foot 4b2 contacts the bottom of the battery box and lifts the battery box. Then, the traveling unit 4a drives the two moving platforms 4 to move along the conveyor track 3 to move the battery box into the inspection cabinet 2 for visual inspection. After the inspection is completed, the moving platform 4 drives the battery box to return to the loading cabinet 1. The linear actuator 4c drives the lifting platform 4b to move down so that the battery box is placed on the loading trolley 1a again. The staff pushes the loading trolley 1a out of the loading cabinet 1 to complete one inspection.
