Description

Technical Field

[0001] This utility model belongs to the field of bottle defect detection technology, specifically, it relates to a bottle rotation positioning structure. Background Technology

[0002] Currently, with the widespread availability of various bottled products, the market demand for various types of bottles is increasing. In order to meet market demand, bottle packaging manufacturers have begun to produce a large number of various types of bottles. Defects may exist in the production of bottles, and these defects can affect the use of the bottles. Therefore, defect detection of bottles is necessary.

[0003] A document with publication number (CN217726281U) discloses a bottle defect detection device. It includes a conveying platform for transporting bottles; one end of the conveying platform is connected to a detection platform to transport the bottles onto the detection platform; the detection platform detects the bottles using visual inspection principles, and along the conveying direction of the bottles are sequentially arranged a verification component for verifying the position of the bottle's detection surface, an adjustment component for rotating the bottle, and a detection component for detecting the bottle's detection surface; simultaneously, two first light source plates are respectively installed on both sides of the connection point between the first conveyor belt and the detection platform to provide detection light for bottles passing between the two first light source plates. A position verification camera is mounted on a quadrangular prism bracket, located above the connection point between the first conveyor belt and the detection platform, to verify the position of the bottle's detection surface passing below the position verification camera. This setup replaces the traditional manual initial screening process for bottle inspection, providing a foundation for subsequent bottle inspection and promotion.

[0004] During use, the bottle moves stably on the production line. The defect detection device can only detect one side of the bottle, which has limited detection effect and limited detection area, resulting in poor defect detection.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the technical problem of bottle defect detection, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A bottle rotation positioning structure includes a base plate with an installation position; a top plate with an installation position, the top plate being movably connected to the base plate; and a rotation positioning assembly disposed between the base plate and the top plate. The rotation positioning assembly is used for rotating, positioning, and transporting the bottle. The rotation positioning assembly includes a mounting base, a placement block, a conveyor belt, and a gear block. The mounting base is fixedly connected to the base plate, the placement block is drivenly connected to the mounting base, the conveyor belt is fixedly connected to the top plate, and the gear block is drivenly connected to the conveyor belt. Corresponding placement blocks and gear blocks are arranged opposite to each other.

[0008] The top plate is symmetrically equipped with transmission rollers, each of which is rotatably connected to the top plate and driven by a motor. Each gear block is rotatably connected to a conveyor belt. Each gear block has a fixed block symmetrically arranged at its bottom, and each fixed block is fixedly connected to the gear block. Each fixed block has a sliding abutment block inside it. Multiple springs are arranged between each fixed block and the abutment block, and the end of each spring is fixedly connected to the corresponding fixed block and the abutment block. Each abutment block is U-shaped, and the end of each abutment block is arc-shaped. The bottom of the top plate is fixedly connected to a mounting frame, and a rack is fixedly connected inside the mounting frame. The corresponding gear block meshes with the rack, and the end of the mounting frame is chamfered.

[0009] In a preferred embodiment of this utility model, a connecting rod is provided between any of the corresponding placement blocks and gear blocks, one end of the connecting rod is fixedly connected to the placement block, and the other end of the connecting rod is fixedly connected to the gear block.

[0010] In a preferred embodiment of this utility model, a transmission belt is slidably connected to the mounting base, and one side of the mounting base protrudes, with each placement block being rotatably connected to the transmission belt.

[0011] In a preferred embodiment of the present invention, the arc end of the mounting base is provided with a sliding groove, and the sliding groove is fixedly connected to the base plate. A cylinder is fixedly connected to the base plate, and the cylinder and the sliding groove are arranged opposite to each other.

[0012] In a preferred embodiment of this utility model, each corner of the base plate is fixedly connected to a hydraulic cylinder, and the output end of each hydraulic cylinder is fixedly connected to the bottom of the top plate.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This bottle rotation positioning structure, by placing a block under the drive of a transmission belt, lifts the bottle to the bottom of the gear block to complete the inspection, and then the cylinder pushes the workpiece to tilt and slide into the chute to achieve directional transportation; the gear block clamps the bottle port through a shaped abutment block and spring cooperation, and drives the bottle to rotate under the meshing drive of the rack, so that its surface is fully exposed for inspection.

[0015] 2. This bottle rotation positioning structure uses a connecting rod to synchronously control the linkage between the placement block and the gear block, ensuring positioning accuracy.

[0016] 3. In this bottle rotation positioning structure, the bottle moves to the corresponding position between the cylinder and the slide. The cylinder pushes the bottom of the bottle through its output end, causing the bottom of the bottle to tilt. The bottom of the bottle aligns with the slide and is placed on the slide. Due to the push from the output end of the cylinder, the bottom structure of the cylinder and the gear block is separated. The bottle slides down in the slide for transportation, and each bottle faces the same direction, reducing the subsequent alignment processing steps for the bottle.

[0017] 4. In this bottle rotation positioning structure, the hydraulic cylinder changes the position of the top plate through the output end, thereby changing the distance between the top plate and the bottom plate and adjusting the distance between the top plate and the bottom plate to a suitable bottle size.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] Please see Figures 1-5A bottle rotation positioning structure includes a base plate 1 with an installation position; a top plate 2 with an installation position, and the top plate 2 is movably connected to the base plate 1; and a rotation positioning assembly disposed between the base plate 1 and the top plate 2. The rotation positioning assembly is used for rotating, positioning, and transporting the bottle. The rotation positioning assembly includes a mounting base 11, a placement block 13, a conveyor belt 21, and a gear block 3. The mounting base 11 is fixedly connected to the base plate 1, the placement block 13 is drively connected to the mounting base 11, and the conveyor belt 21 is fixedly connected to the top plate 2. Gear block 3 is connected to conveyor belt 21 for transmission. The corresponding placement block 13 is set opposite to gear block 3. The bottle is lifted to the bottom of gear block 3 by placement block 13 under the drive of transmission belt 12 to complete the inspection. Then, cylinder 5 pushes the workpiece to tilt and slide into slide groove 51 to achieve directional transportation. Gear block 3 clamps the bottle port through the cooperation of shaped abutment block 42 and spring 41. Under the meshing drive of rack 32, it drives the bottle to rotate so that its surface is fully exposed for inspection. Connecting rod 6 synchronously controls the linkage between placement block 13 and gear block 3 to ensure positioning accuracy.

[0028] The top plate 2 is symmetrically equipped with drive rollers 22, each of which is rotatably connected to the top plate 2 and driven by a motor. Each gear block 3 is rotatably connected to the conveyor belt 21. A fixing block 4 is symmetrically arranged at the bottom of each gear block 3, and each fixing block 4 is fixedly connected to the gear block 3. An abutment block 42 is slidably connected within each fixing block 4. Multiple springs 41 are arranged between each fixing block 4 and the abutment block 42, and the end of each spring 41 is fixedly connected to the corresponding fixing block 4 and abutment block 42. Each abutment block 42 is U-shaped. The end of the bottle is arc-shaped. The motor drives the transmission roller 22 to rotate, which in turn drives the conveyor belt 21 to rotate. The conveyor belt 21 drives the gear block 3 to move. After the gear block 3 moves to the appropriate position, the abutment block 42 at the bottom of the gear block 3 abuts against the top of the bottle. Due to the U-shaped shape of the abutment block 42, the arc shape of the abutment block 42 pushes the abutment block 42 to both sides during the contact with the end of the bottle. The abutment block 42 compresses the spring 41, which deforms and applies the deformation force to the abutment block 42. The abutment block 42 abuts tightly against the end of the bottle, fixing the end of the bottle and restricting the position of the bottle.

[0029] The top plate 2 has a mounting bracket 31 fixedly connected to its bottom. A rack 32 is fixedly connected inside the mounting bracket 31, and a corresponding gear block 3 meshes with the rack 32. The end of the mounting bracket 31 has a chamfer. A connecting rod 6 is provided between any corresponding placement block 13 and the gear block 3. One end of the connecting rod 6 is fixedly connected to the placement block 13, and the other end is fixedly connected to the gear block 3. After the gear block 3 moves to the position of the mounting bracket 31, the chamfer at the end of the mounting bracket 31 guides the sliding position of the gear block 3, sending it into the mounting bracket 31. During the movement of the gear block 3... Engaging with rack 32, gear block 3 rotates during movement, causing the bottle to rotate during movement. This exposes the bottle's wall surface to the inspection body during movement, allowing for more thorough inspection and preventing inadequate defect detection. As gear block 3 moves, it drives the corresponding placement block 13 via connecting rod 6. Placement block 13 then drives transmission belt 12 to slide within mounting base 11. Through the cooperation between placement block 13, gear block 3, connecting rod 6, and other components, synchronization is achieved between the up and down transmissions within the device, preventing asynchronous movement between placement block 13 and gear block 3 and ensuring effective bottle positioning.

[0030] It is worth noting that connecting rod 6 is a telescopic rod. Since telescopic rods are a mature technology, they have not been fully disclosed in this article and will not be elaborated on here.

[0031] The mounting base 11 is slidably connected to a transmission belt 12, and one side of the mounting base 11 is raised. Each placement block 13 is rotatably connected to the transmission belt 12. The arc end of the mounting base 11 is provided with a sliding groove 51, and the sliding groove 51 is fixedly connected to the base plate 1. A cylinder 5 is fixedly connected to the base plate 1, and the cylinder 5 is positioned opposite to the sliding groove 51. When the bottle is placed on the placement block 13, after the transmission belt 12 moves to the raised position of the mounting base 11, the placement block 13 drives the bottle upward. The bottle is driven to make close contact with the structure at the bottom of the gear block 3. After the test is completed, the placement block 13 is removed. The raised position is opened, and the placement block 13 is separated from the bottom of the bottle. The gear block 3 continuously drives the bottle to move, completing the continuous conveying and continuous detection of the bottle. The bottle moves to the corresponding position between the cylinder 5 and the slide 51. The cylinder 5 pushes the bottom of the bottle through the output end, and the bottom of the bottle tilts. The bottom of the bottle is aligned with the slide 51 and placed on the slide 51. Due to the push of the output end of the cylinder 5, the port of the bottle separates the bottom structure of the cylinder 5 from the gear block 3. The bottle slides down in the slide 51 for transportation, and each bottle faces the same direction, reducing the subsequent processing steps of aligning the bottle's orientation.

[0032] Each corner of the base plate 1 is fixedly connected to a hydraulic cylinder 52, and the output end of each hydraulic cylinder 52 is fixedly connected to the bottom of the top plate 2. The hydraulic cylinder 52 changes the position of the top plate 2 through the output end, thereby changing the distance between the top plate 2 and the base plate 1 and adjusting the distance between the top plate 2 and the base plate 1 to a suitable bottle size.

[0033] A 360° defect detection device includes a detection body, which is fixedly connected to the middle of a base plate 1. The detection head of the detection body is opposite to the protrusion of the mounting base 11. The bottle is lifted to the bottom of the gear block 3 by the placement block 13 driven by the transmission belt 12 to complete the detection. Then, the workpiece is pushed by the cylinder 5 to tilt and slide into the slide groove 51 to achieve directional transportation. The gear block 3 clamps the bottle port through the cooperation of the shaped abutment block 42 and the spring 41. Under the meshing drive of the rack 32, the bottle rotates so that its surface is fully exposed for detection. The connecting rod 6 synchronously controls the linkage between the placement block 13 and the gear block 3 to ensure positioning accuracy.

[0034] It is worth noting that the detection body includes a detection table and an air compressor, baffles, blocking electric push rods, mounting plates, universal metal hoses, connecting frames, and a detection camera, which facilitates the simultaneous detection of the internal and external conditions of the bottle. The detection body has already been disclosed in a 360° bottle cap external defect detection device CN220781354U in the prior art, and will not be described in detail here.

[0035] Working principle: The bottle is placed on the placement block 13. After the transmission belt 12 moves to the protruding position of the mounting base 11, the placement block 13 drives the bottle upward. The bottle is driven to make close contact with the structure at the bottom of the gear block 3. After the test is completed, the placement block 13 moves away from the protruding position and separates from the bottom of the bottle. The gear block 3 continues to drive the bottle to move, completing the continuous conveying and continuous testing of the bottle. The bottle moves to the corresponding position between the cylinder 5 and the slide 51. The cylinder 5 pushes the bottom of the bottle through the output end, tilting the bottom of the bottle. The bottom of the bottle aligns with the slide 51 and is placed on the slide 51. The port of the bottle is pushed by the output end of cylinder 5, separating cylinder 5 from the bottom structure of gear block 3. The bottle slides down in the chute 51 for transportation, and each bottle faces the same direction, reducing the subsequent alignment processing steps. The motor drives the transmission roller 22 to rotate, which in turn drives the conveyor belt 21 to rotate. The conveyor belt 21 drives the gear block 3 to move. After the gear block 3 moves to the appropriate position, the abutment block 42 at the bottom of the gear block 3 abuts against the top of the bottle. Due to the U-shape of the abutment block 42, the arc shape of the abutment block 42 pushes the abutment block 42 to both sides during the contact with the port of the bottle. 2. The spring 41 is compressed, and the spring 41 deforms and applies the deformation force to the abutment block 42. The abutment block 42 abuts tightly against the end of the bottle, fixing the end of the bottle and restricting its position. After the gear block 3 moves to the position of the mounting bracket 31, the chamfer at the end of the mounting bracket 31 guides the sliding position of the gear block 3, sending the gear block 3 into the mounting bracket 31. During the movement, the gear block 3 meshes with the rack 32 and rotates. The gear block 3 drives the bottle to rotate during the movement, exposing the bottle wall to the inspection body during the movement, making the inspection of the bottle more accurate. To ensure adequate detection of bottle defects, the gear block 3 moves, driving the corresponding placement block 13 to move via the connecting rod 6. The placement block 13 then drives the transmission belt 12 to slide within the mounting base 11. Through the cooperation between the placement block 13, gear block 3, connecting rod 6, and other components, synchronization is achieved between the upper and lower transmissions within the device, preventing asynchronous movement between the placement block 13 and gear block 3 that could lead to loss of bottle positioning. The hydraulic cylinder 52 changes the position of the top plate 2 via its output end, altering the distance between the top plate 2 and the bottom plate 1, thus adjusting the distance between the top plate 2 and the bottom plate 1 to a suitable bottle size.
