Description
Technical Field
[0001] This utility model relates to the field of automated production equipment technology, specifically a vacuum adsorption platform that is easy to position. Background Technology
[0002] Vacuum adsorption platforms are widely used in automated product adsorption. Simply place the product on the platform and vacuum adsorb it, greatly improving factory production efficiency. However, current adsorption platforms on the market are only suitable for products with FPCs at the front end, making them incompatible with products having FPCs at both the front and back. Cameras cannot sequentially acquire front and back images from below the product, requiring positioning and processing at different angles, increasing processing difficulty and reducing production efficiency. Furthermore, the fixed opening design cannot effectively accommodate FPCs of different sizes or irregular shapes, easily causing vibrations during processing and resulting in image distortion. Therefore, we propose a vacuum adsorption platform that facilitates positioning. Utility Model Content
[0003] The purpose of this invention is to provide a vacuum adsorption platform that is easy to position, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A vacuum adsorption platform for easy positioning includes a device body, a positioning platform fixedly connected to the outer surface of the device body, an opening penetrating the outer surface of the positioning platform, and a positioning mechanism for flexibly clamping workpieces disposed inside the positioning platform. The positioning mechanism includes: A positioning plate, the side wall of which is slidably connected to the inner side wall of the opening, a limiting groove is formed on the bottom surface of the opening, one end of a first telescopic rod is fixedly connected to the end of the limiting groove, a lower hinge block is fixedly connected to the other end of the first telescopic rod, a first telescopic spring is sleeved on the outer surface of the first telescopic rod, and a connecting arm is hinged to the upper surface of the lower hinge block. The upper hinge seat is hinged to the end of the connecting arm away from the lower hinge block. The bottom surface of the positioning plate is provided with a sliding groove. A limit rod is fixedly connected to the end of the sliding groove. The outer wall of the limit rod is slidably connected to the inner wall of the upper hinge seat.
[0005] Preferably, there are two sets of connecting arms, and the two sets of connecting arms are distributed in a mirror-symmetrical manner at the upper end of the lower hinge block, and the two sets of connecting arms are connected by a connecting shaft.
[0006] Preferably, the side wall of the lower hinge block is slidably connected to the inner wall of the limiting groove, and two sets of the first telescopic rods are provided, with the two sets of the first telescopic rods being distributed in a mirror-symmetrical manner inside the limiting groove.
[0007] Preferably, the positioning plate is provided with a compensation mechanism for dynamically compensating the outer shell of the irregular workpiece. The compensation mechanism includes a mounting groove, which is opened on the upper surface of the positioning plate. A second telescopic rod is fixedly connected to the bottom surface of the mounting groove. A support block is slidably connected to the inner wall of the mounting groove. A connecting groove is opened on the bottom surface of the support block. The end of the second telescopic rod away from the limiting rod is fixedly connected to the upper surface of the connecting groove.

[0011] Compared with the prior art, this utility model provides a vacuum adsorption platform that is easy to position, and has the following beneficial effects: 1. This easy-to-position vacuum adsorption platform, through the setting of a positioning mechanism, cooperates with the positioning plate to slide inside the opening. Combined with the first telescopic rod and the first telescopic spring in the limiting groove, it can automatically adjust the clamping force to adapt to workpieces of different sizes. The connecting arms are distributed in a mirror symmetry and connected by a connecting shaft, which enhances the stability and synchronization of the structure and ensures that the workpiece will not shift or loosen during the positioning process. At the same time, the upper hinge seat slides and connects with the limiting rod in the slide groove, making the positioning plate more stable when moving, improving the positioning accuracy and efficiency, reducing adjustment time, and making it suitable for high-speed or precision machining scenarios.
[0012] 2. This easy-to-position vacuum adsorption platform, through the setting of a compensation mechanism, combined with the linear array distribution of multiple sets of support blocks and the cooperation of the second telescopic rod and spring, dynamically compensates for the shell of irregular workpieces. Each support block is independently installed in the mounting slot and provides elastic support through the second telescopic spring. When the surface of the workpiece is irregular, the support block can adaptively adjust its height to ensure that the workpiece is in full contact with the adsorption platform.

Detailed Implementation
[0015] like Figures 1-4 As shown, this utility model provides a technical solution: a vacuum adsorption platform that is easy to position, including a device body 1, a positioning platform 3 fixedly connected to the outer surface of the device body 1, an opening 31 through the outer surface of the positioning platform 3, and a positioning mechanism 4 for flexibly clamping workpieces is provided inside the positioning platform 3. The positioning mechanism 4 includes: a positioning plate 41, a limiting groove 42, a first telescopic rod 43, a first telescopic spring 44, a lower hinge block 45, a connecting arm 46, a connecting shaft 47, an upper hinge seat 48, a sliding groove 49, and a limiting rod 410.
[0016] In one embodiment of this utility model, the sidewall of the positioning plate 41 is slidably connected to the inner sidewall of the opening 31. A limiting groove 42 is formed on the bottom surface of the opening 31. One end of the first telescopic rod 43 is fixedly connected to the end of the limiting groove 42. The other end of the first telescopic rod 43 is fixedly connected to the lower hinge block 45. A first telescopic spring 44 is sleeved on the outer surface of the first telescopic rod 43. A connecting arm 46 is hinged to the upper surface of the lower hinge block 45. An upper hinge seat 48 is hinged to the end of the connecting arm 46 away from the lower hinge block 45. A sliding groove 49 is formed on the bottom surface of the positioning plate 41. A limiting rod 410 is fixedly connected to the end of the sliding groove 49. The outer wall of the limiting rod 410 is slidably connected to the inner wall of the upper hinge seat 48. Two sets of connecting arms 46 are provided, and the two sets of connecting arms 46 are distributed in a mirror symmetrical manner on the upper end of the lower hinge block 45. The two sets of connecting arms 46 are connected by a connecting shaft 47. The sidewall of the lower hinge block 45 is connected to the limiting rod 46. The inner wall of the positioning groove 42 is slidably connected. There are two sets of first telescopic rods 43. The two sets of first telescopic rods 43 are distributed in a mirror symmetrical manner inside the positioning groove 42. The positioning plate 41 can slide in the opening 31. Under the combined action of the first telescopic rods 43 and the first telescopic spring 44, the sliding positioning plate 41, in conjunction with the connecting arm 46 and the connecting shaft 47, can provide space for the positioning plate 41 to move up and down. When the positioning plate 41 moves downward, the upper hinge seat 48 set at the lower end of the positioning plate 41 will slide on the outer surface of the limiting rod 410 under the restriction of the slide groove 49. The upper hinge seat 48 slides towards both ends of the slide groove 49, which will simultaneously drive the connecting arm 46 to open around the connecting shaft 47, and simultaneously drive the lower hinge block 45 to slide towards both ends of the positioning groove 42, which will squeeze the first telescopic spring 44. The reaction force formed by squeezing the first telescopic spring 44 provides support for the positioning plate 41.
[0017] In addition, the positioning plate 41 is internally equipped with a compensation mechanism 5 for dynamic compensation of the irregular workpiece shell. The compensation mechanism 5 includes a mounting groove 51, which is formed on the upper surface of the positioning plate 41. A second telescopic rod 52 is fixedly connected to the bottom surface of the mounting groove 51. A support block 55 is slidably connected to the inner wall of the mounting groove 51. A connecting groove 54 is formed on the bottom surface of the support block 55. The end of the second telescopic rod 52 away from the limiting rod 410 is fixedly connected to the upper surface of the connecting groove 54. A second telescopic spring 53 is sleeved on the outer surface of the second telescopic rod 52. The number of blocks 55 is set in multiple sets, and the multiple sets of support blocks 55 are distributed in a linear array inside the mounting groove 51. The side walls of the support blocks 55 located on the side of the mounting groove 51 are provided with rounded corners. The arrangement of multiple sets of support blocks 55 can dynamically compensate for the shell of irregularly shaped products. With the cooperation of the second telescopic spring 53 and the second telescopic rod 52, the multiple sets of support blocks 55 distributed in a linear array can independently clamp the shell of the product. When the outer surface of the product is irregular, the height can be adaptively adjusted to further ensure the contact between the product and the positioning platform 3.
[0018] In this embodiment of the utility model, the side wall of the positioning platform 3 is provided with a vacuum hole 32, the outer wall of the positioning platform 3 is provided with a vacuum adsorption port 33, the outer surface of the positioning platform 3 is detachably connected with a fixing screw 34, and the lower surface of the device body 1 is fixedly connected with a camera 2. The camera 2 is set on the back side of the positioning platform 3. The positioning platform 3 can be vacuumed through the vacuum hole 32, and the product can be adsorbed in conjunction with the vacuum adsorption port 33. Furthermore, the positioning platform 3 can be flexibly installed and disassembled through the fixing screw 34, which is convenient for staff to perform maintenance and repair. The camera 2 can provide a clear image of the product.
[0019] In this invention, during use, the workpiece presses down on the positioning plate 41, causing it to slide along the side wall of the opening 31. The sliding groove 49 on the bottom surface of the positioning plate 41 pushes the upper hinge seat 48 to move along the limiting rod 410. Then, through the connecting arm 46, the lower hinge block 45 is pushed to compress the first telescopic spring 44 and the first telescopic rod 43 in the limiting groove 42. The restoring force of the hinge telescopic structure is used to achieve flexible clamping and positioning of the workpiece. At the same time, for irregularly shaped workpieces, the multiple sets of support blocks 55 of the compensation mechanism 5 can slide independently in the mounting groove 51, and dynamically adjust their height by compressing their respective second telescopic springs 53 and second telescopic rods 52 to fit the bottom surface of the workpiece. Finally, the vacuum acts on the lower surface of the workpiece through the vacuum suction port 33 and the vacuum hole 32. Combined with the auxiliary locking of the fixing screw 34 and the back-side monitoring of the camera 2, the stable adsorption and positioning of the workpiece is completed.
[0020] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
