Description

Technical Field

[0001] This utility model relates to the field of production technology and equipment for sealing caps, and in particular to a movable positioning mechanism for sealing caps. Background Technology

[0002] After the sealing cap is formed, it needs to be visually inspected before packaging. However, in existing technology, after the sealing cap is formed, it is removed from the LSR (liquid silicone) molding machine by a six-axis robot and placed on a positioning plate for positioning. After being positioned by the positioning plate, the sealing cap is then inspected by software recognition using a CCED camera and a standard image of the sealing cap to reject products with poor molding or burrs. However, due to the small size of the sealing cap, it is often difficult to accurately position the sealing cap on the positioning plate by the six-axis robot. This causes detection deviations in the CCED camera during the inspection process, resulting in false detections of defective sealing caps. Therefore, a precise positioning mechanism for the sealing cap is needed to ensure accurate positioning during the visual inspection process and avoid detection deviations in the CCED camera. Summary of the Invention

[0003] Therefore, to address the positioning issue during the appearance inspection of the sealing cover, a precise positioning mechanism needs to be designed. This can be achieved by using a six-axis robot to initially position the sealing cover on the positioning mechanism, and then precisely positioning the sealing cover onto the positioning mechanism. This solves the problem of detection deviation during the inspection process of the CCED camera.

[0004] To achieve the above objectives, this utility model provides a movable positioning mechanism for a sealing cap, comprising a support platform with a table surface and a slide rail on the table surface. A movable seat slides along the slide rail, and the movable seat includes a positioning plate. The positioning plate has multiple sets of positioning blocks for positioning the sealing cap. Each set of positioning blocks includes a fixed positioning block and a pair of opposing and adjustable positioning blocks. The fixed positioning block and the pair of opposing positioning blocks form a preliminary positioning of the three sides of the sealing cap. A movable pressure plate is provided above the positioning plate, and a pair of opposing pressing cylinders are provided on the positioning plate. The telescopic rod end of the pressing cylinder is connected to the movable pressure plate. The movable pressure plate has multiple pressing fingers extending between the multiple sets of positioning blocks. One pressing cylinder telescopically presses the pressing fingers toward the positioning block to press the sealing cap tightly, while the other pressing cylinder telescopically moves the pressing fingers away from the positioning block to release the sealing cap. With the movable pressure plate released, the sealing cap is removed from the LSR (liquid silicone) molding machine by a six-axis robot. The sealing cap is initially positioned on three sides by the positioning blocks. At this initial positioning, the requirements for the six-axis robot to place the sealing cap are low, and the six-axis robot can easily fix the sealing cap between the positioning blocks. After the positioning blocks are positioned, the movable pressure plate presses the sealing cap tightly against the positioning blocks to achieve accurate positioning of the positioning blocks, thereby ensuring the positioning accuracy of the sealing cap in the subsequent appearance inspection process.

[0005] Furthermore, the pressing cylinder has a first connecting plate at the end of its telescopic rod, and the first connecting plate is connected to the bottom of the movable pressure plate. The pressing cylinder connects to the movable pressure plate through the first connecting plate, thereby enabling the pressing cylinder to press or release the movable pressure plate.

[0006] Furthermore, the positioning plate has a pair of support parts located below the movable pressure plate, and a positioning rod is provided between the support parts, with the positioning rod passing through the first connecting plate. When the pressing cylinder pushes the first connecting plate, the first connecting plate is moved and positioned by the positioning rod, ensuring that the movable pressure plate can be pressed or released more smoothly.

[0007] Furthermore, the positioning plate has multiple pairs of adjustment slots for adjusting and fixing the positioning blocks. The positioning blocks, which are arranged opposite each other, are adjusted and positioned through the adjustment slots to ensure that the positioning plate can be fixed according to the sealing caps of different product specifications.

[0008] Furthermore, the movable seat includes a base plate connected to the positioning plate, and a sliding block is provided at the bottom of the base plate. The sliding block is slidably engaged with the slide rail, and the movable seat slides through the sliding engagement between the sliding block and the slide rail.

[0009] Furthermore, a rodless cylinder is connected to the base plate for the movable seat to slide on the slide rail. The rodless cylinder includes a sliding sensing block, and a second connecting plate is provided on the sensing block, which is connected to the base plate. When the movable seat slides, the rodless cylinder pushes the sensing block, and the sensing block realizes the sliding positioning of the movable seat through the second connecting plate. Through the sliding of the movable seat, the sealing caps positioned on the positioning plate can be sequentially inspected for their positioning and appearance by an external CCED camera.

[0010] Furthermore, a pair of limiters are provided at each end of the slide rail, and a limiting part corresponding to the limiters is provided on the base plate. When the moving seat slides by the rodless cylinder, the limiters at both ends of the slide rail are used to elastically limit the two ends of the moving seat, preventing the sealing cover from disengaging from the positioning space due to a sudden stop in movement when the moving seat moves to the two ends of the slide rail.

[0011] In this invention, the sealing cap is initially positioned on the positioning plate using a positioning block. After the sealing cap is initially positioned, it is pushed by a movable pressure plate and pressed by a pressure finger, so that the sealing cap abuts against the positioning block to achieve accurate positioning of the positioning block. This ensures the positioning accuracy of the sealing cap in the subsequent appearance inspection process and greatly improves the positioning accuracy of the sealing cap. Attached Figure Description

Detailed Implementation

[0018] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0019] A movable positioning mechanism for a sealing cap, as described in the following text. Figures 1-4 The system includes a support platform 1, which has a table surface 11. A slide rail 3 is mounted on the table surface 11, and a movable seat 2 slides along the slide rail 3. The movable seat 2 includes a positioning plate 21 and a base plate 23 connected to the positioning plate 21. A sliding block 29 is located at the bottom of the base plate 23, and the sliding block 29 slides along the slide rail 3. The movable seat 2 slides through the sliding engagement of the sliding block 29 and the slide rail 3. The positioning plate 21 has multiple sets of positioning blocks 22 for positioning the sealing cover 4. Each set of positioning blocks 22 includes a fixed positioning block 22 and a... For the relatively arranged and adjustable positioning blocks 22, the fixed positioning block 22 and a pair of relatively arranged positioning blocks 22 form a preliminary positioning of the three sides of the sealing cover 4. The positioning plate 21 has multiple pairs of adjustment grooves 211 for adjusting and fixing the positioning blocks 22. The relatively arranged positioning blocks 22 are adjusted and positioned through the adjustment grooves 211 to ensure that the positioning plate 21 can be fixed according to the sealing cover 4 of different product specifications. A movable pressure plate 24 is provided above the positioning plate 21, and a pair of relatively arranged pressing cylinders are provided on the positioning plate 21. 25. The telescopic rod end of the pressing cylinder 25 is provided with a first connecting plate 26, which is connected to the bottom of the movable pressure plate 24. The pressing cylinder 25 connects to the movable pressure plate 24 through the first connecting plate 26. The movable pressure plate 24 is provided with multiple pressing fingers 241 extending between multiple sets of positioning blocks 22. One pressing cylinder 25 can telescopically move the pressing fingers 241 toward the positioning blocks 22 to press the sealing cover 4 tightly. Another pressing cylinder 25 can telescopically move the pressing fingers 241 away from the positioning blocks 22 to release the sealing cover 4. 4. In the loosened state, the sealing cap 4 is taken out from the LSR (liquid silicone) molding machine by a six-axis robot. The sealing cap 4 is initially positioned on three sides by the positioning block 22. At this initial positioning, the requirements for the six-axis robot to place the sealing cap 4 are low. The six-axis robot can easily fix the sealing cap 4 between the positioning blocks 22. After the positioning block 22 is positioned, the sealing cap 4 is pressed and abutted against the positioning block 22 by the movable pressure plate 24 to achieve accurate positioning of the positioning block 22, thereby ensuring the positioning accuracy of the sealing cap 4 in the subsequent appearance inspection process.

[0020] In this embodiment, to ensure the smooth sliding of the movable pressure plate 24, refer to Figure 5 The positioning plate 21 has a pair of support parts 28 located below the movable pressure plate 24. A positioning rod 27 is provided between the support parts 28, and the positioning rod 27 passes through the first connecting plate 26. The first connecting plate 26 is moved and positioned by means of the positioning rod 27. When the pressing cylinder 25 pushes the first connecting plate 26, it ensures that the movable pressure plate 24 can be pressed or released more smoothly.

[0021] In this embodiment, to ensure the positioning and movement of the movable seat 2, a rodless cylinder 6 is connected to the base plate 23 of the movable seat 2 for the movable seat 2 to slide on the slide rail 3. The rodless cylinder 6 includes a sliding sensing block 61, and a second connecting plate 62 is provided on the sensing block 61. The second connecting plate 62 is connected to the base plate 23. When the movable seat 2 slides, the rodless cylinder 6 pushes the sensing block 61, and the sensing block 61 realizes the sliding positioning of the movable seat 2 through the second connecting plate 62. Thus, through the sliding of the movable seat 2, the sealing cover 4 positioned on the positioning plate 21 can be sequentially inspected for its positioning appearance by passing under the external CCED camera.

[0022] In this embodiment, in order to improve the stability of the sealing cover 4 after it stops sliding at both ends, a pair of limiters 5 are provided at both ends of the slide rail 3. Correspondingly, a limiting part 231 corresponding to the limiter 5 is provided on the base plate 23. When the moving seat 2 slides through the rodless cylinder 6, the limiters 5 at both ends of the slide rail 3 are used to achieve elastic limiting at both ends of the moving seat 2, which can prevent the sealing cover 4 from disengaging from the positioning blocks 22 due to the sudden stop of movement when the moving seat 2 moves to both ends of the slide rail 3.

[0023] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
