Description

Technical Field

[0001] This utility model relates to the field of electronic product testing technology, specifically to a compact cam flipping mechanism. Background Technology

[0002] The flipping mechanism is a key module in automated equipment. When a product needs to be reoriented during production, a flipping mechanism is required to complete the task. Existing flipping mechanisms all use cylinders or motors to rotate independently. The cylinders support the product to complete the rotation, which is complex and takes up a lot of space. Therefore, it is particularly important to develop an effective and stable flipping mechanism.

[0003] In existing technologies, some traditional cylinder tilting mechanisms require an additional cylinder to control the extension and retraction of the upper and lower material trays simultaneously. This results in a complex, bulky, and space-consuming equipment structure, and the tilting mechanism is prone to vibration. In addition, some cylinder tilting mechanisms use mechanical structures such as blocks or bolts for limiting, but mechanical contact usually has a springback problem, resulting in low tilting repeatability and difficulty in meeting the correction requirements of precision components. Furthermore, when the cylinder reaches its end point and relies on mechanical buffering, it still generates a small impact, which may cause micro-cracks and other damage to brittle components. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a compact cam flipping mechanism that effectively solves the problems of traditional cylinder flipping mechanisms in the prior art, which typically require an additional cylinder to control the extension and retraction of the upper and lower material plates simultaneously, and the slight impact that still occurs at the end of the cylinder despite mechanical buffering.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a compact cam flipping mechanism, including a support mechanism, including a fixed frame, a positioning carrier located directly above the fixed frame, a plurality of placement slots penetrating the surface of the positioning carrier and used to accommodate the product to be tested, and a sheet metal cover fixedly connected to the top of the fixed frame.

[0007] The flipping mechanism includes a drive assembly for powering the flipping of the positioning carrier and the placement slot, as well as a shielding assembly and a force-applying assembly that cooperate to prevent the product to be tested from falling out of the placement slot during the flipping process.

[0008] The driving component is located inside the sheet metal cover, and both the shielding component and the force-applying component are located inside the sheet metal cover.

[0009] The shielding component is provided in two sets and is arranged in parallel inside the force-applying component;

[0010] The drive assembly includes a servo motor adapted to be installed on the outside of the fixed frame, a reducer fixedly connected to the outer surface of the fixed frame and used in conjunction with the servo motor, a synchronous belt sleeved on the output end of the reducer via a pulley, and a rotating rod sleeved on the inner surface of the other end of the synchronous belt via a pulley.

[0011] Furthermore, the drive assembly also includes a connecting post fixedly installed on the outer end face of the rotating rod, a limiting groove formed on both sides of the connecting post, a spring fixedly installed on the inner walls of both sides of the limiting groove, and a photoelectric sensor fixedly sleeved on the outer surface of the connecting post.

[0012] Furthermore, the outer end face of the drive assembly is fixedly mounted to the outer surface of the fixing frame via a bearing, and the photoelectric sensor is used to detect the flip position and angle of the connecting column.

[0013] Furthermore, the shielding assembly includes a force-bearing column slidably connected to the inner wall of the limiting groove, and a sliding rod fixedly connected to the outer end face of the force-bearing column.

[0014] Furthermore, the slide rod is slidably connected to the inner wall of the connecting column, and the outer end face of the spring is fixedly connected to the outer end face of the slide rod.

[0015] Furthermore, the shielding assembly also includes a material support plate fixedly installed at the through end of the slide bar and used to prevent the product to be tested from falling off the placement slot, the material support plate being respectively disposed on both sides of the positioning carrier.

[0016] Furthermore, the force-applying component includes a fixed sleeve fixedly installed on the top of the fixed frame, and a force-applying end integrally formed on the outer end face of the fixed sleeve and used in conjunction with the force-bearing column.

[0017] Furthermore, the outer surface of the connecting column slides in contact with the inner wall of the fixing sleeve;

[0018] When the force-bearing column rotates to the position where it contacts the force-applying end, it will be squeezed by the outer contour of the force-applying end, thereby driving the slide bar and the material support plate to move synchronously, so that the material support plate can release the obstruction above the placement groove.

[0019] Meanwhile, the slide bar on the other side, under the elastic force of the spring, drives the material support plate to move to the position that blocks the placement groove, thereby preventing the product to be processed from falling out of the placement groove.

[0020] Beneficial effects:

[0021] This invention, by setting up a flipping mechanism, can not only automatically prevent the product to be tested from falling off when driving the positioning carrier, the placement slot and the product to be tested to flip without adding an extra cylinder, but also avoids the problems of complex, bulky and space-consuming traditional cylinder flipping mechanisms, as well as the problem of small impacts caused by mechanical buffering at the end of the cylinder. This achieves the effect of ensuring the compactness of the mechanism and the stability of the flipping process, while avoiding damage to brittle components. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example: A compact cam flipping mechanism, see attached figure. Figure 1 - Appendix Figure 7 ,include,

[0034] The support mechanism 100 includes a fixed frame 110, a positioning carrier 120 located directly above the fixed frame 110, a plurality of placement slots 130 penetrating the surface of the positioning carrier 120 and used to accommodate the product to be tested, and a sheet metal cover 140 fixedly connected to the top of the fixed frame 110.

[0035] It should be noted that the fixing bracket 110 is used to fix and install the various components of the flipping mechanism 200 to ensure the stability of the overall structure. The positioning carrier 120 is used to support the product to be tested, and the placement groove 130 on its surface can accommodate the product and limit lateral displacement to ensure the stability of the product position during the flipping process. The sheet metal cover 140 is used to enclose the drive assembly 210, the shielding assembly 220, etc., to provide protection and dust prevention, while reducing external interference.

[0036] The flipping mechanism 200 includes a drive assembly 210 for powering the flipping of the positioning carrier 120 and the placement slot 130, and a shielding assembly 220 and a force application assembly 230 to prevent the product to be tested from falling out of the placement slot 130 during the flipping process.

[0037] The drive assembly 210 is located inside the sheet metal cover 140, and the shielding assembly 220 and the force application assembly 230 are both located inside the sheet metal cover 140.

[0038] Two sets of shielding components 220 are provided and are arranged in parallel inside the force-applying component 230;

[0039] The drive assembly 210 includes a servo motor 211 adapted to be installed on the outside of the fixed frame 110, a reducer 212 fixedly connected to the outer surface of the fixed frame 110 and used in conjunction with the servo motor 211, a synchronous belt 213 sleeved on the output end of the reducer 212 via a pulley, and a rotating rod 214 sleeved on the inner surface of the other end of the synchronous belt 213 via a pulley.

[0040] Specifically, the drive assembly 210 also includes a connecting post 215 fixedly installed on the outer end face of the rotating rod 214, a limiting groove 216 opened on both sides of the connecting post 215, a spring 217 fixedly installed on both sides of the inner wall of the limiting groove 216, and a photoelectric sensor 218 fixedly sleeved on the outer surface of the connecting post 215.

[0041] It should be noted that the servo motor 211 and the reducer 212 work together to output rotational power, which drives the rotating rod 214 to rotate via the synchronous belt 213, providing stable power for the subsequent flipping motion. Compared with traditional cylinder drive, the servo motor 211 and the reducer 212 can achieve high-precision speed and angle control, avoiding mechanical impact. The rotating rod 214 is used to drive the connecting column 215 to rotate synchronously. As the core transmission component of the flipping action, the connecting column 215 can drive the blocking component 220 to move through the limit grooves 216 on both sides. Finally, the force application component 230 drives the material support plate 223 to complete the extension action. The spring 217 is used to push the slide bar 222 to reset and drive the material support plate 223 to extend automatically. The photoelectric sensor 218 is used to detect the flipping position and angle of the connecting column 215 in real time and feed the signal to the control system to ensure that the flipping stops accurately at the 180-degree position, replacing the traditional mechanical limit and eliminating the rebound error.

[0042] Furthermore, the outer end face of the drive assembly 210 is fixedly mounted on the outer surface of the mounting bracket 110 via a bearing, and the photoelectric sensor 218 is used to detect the flip position and angle of the connecting column 215.

[0043] Preferably, the shielding assembly 220 includes a force-bearing column 221 slidably connected to the inner wall of the limiting groove 216, and a slide rod 222 fixedly connected to the outer end face of the force-bearing column 221.

[0044] It should be noted that the slide rod 222 is slidably connected to the inner wall of the connecting column 215, and the outer end face of the spring 217 is fixedly connected to the outer end face of the slide rod 222.

[0045] Furthermore, the shielding assembly 220 also includes a material support plate 223 fixedly installed at the through end of the slide bar 222 and used to prevent the product to be tested from falling off the placement slot 130. The material support plate 223 is respectively provided on both sides of the positioning carrier 120.

[0046] Specifically, the force-applying component 230 includes a fixed sleeve 231 fixedly installed on the top of the fixed frame 110, and a force-applying end 232 integrally formed on the outer end face of the fixed sleeve 231 and used in conjunction with the force-bearing column 221.

[0047] It should also be noted that the fixed sleeve 231 is used to provide rotational support for the connecting column 215. The force-applying end 232 is convex at the top and concave at the bottom. When the connecting column 215 drives the force-receiving column 221 to rotate until it contacts the protrusion of the force-applying end 232, the force-applying end 232 will squeeze the force-receiving column 221, forcing the slide rod 222 and the material support plate 223 to retract synchronously. When the connecting column 215 drives the force-receiving column 221 to rotate until it disengages from the protrusion of the force-applying end 232, the reaction force of the spring 217 will drive the slide rod 222 and the material support plate 223 to extend synchronously.

[0048] Preferably, the outer surface of the connecting post 215 slides in contact with the inner wall of the fixing sleeve 231;

[0049] When the force-bearing column 221 rotates to the position where it contacts the force-applying end 232, it will press the outer contour of the force-applying end 232, thereby driving the slide bar 222 and the material support plate 223 to move synchronously, so that the material support plate 223 can release the obstruction above the placement groove 130.

[0050] Meanwhile, the slide bar 222 on the other side, under the elastic force of the spring 217, drives the material support plate 223 to move to the position of blocking the placement groove 130, thereby preventing the product to be processed from falling out of the placement groove 130.

[0051] When using,

[0052] The product to be tested is placed in the placement slot 130 of the positioning carrier 120 in the bearing mechanism 100, and the product to be tested is supported by the material support plate 223 to prevent it from falling off.

[0053] Then the servo motor 211 is started to output rotational power. After the rotational power is reduced by the reducer 212, it drives the rotating rod 214 to rotate through the synchronous belt 213, and then drives the connecting column 215 to rotate synchronously through the rotating rod 214.

[0054] When the connecting column 215 rotates: the photoelectric sensor 218 on its outer surface detects the flip position and angle in real time and feeds it back to the control system to ensure accurate flipping of 180 degrees. At the same time, through the cooperation of the connecting column 215 and the limiting groove 216, the force-bearing column 221 is driven to perform circular motion.

[0055] When the force-bearing column 221 rotates to the position where it contacts the protrusion of the force-applying end 232: the force-applying end 232 is squeezed by the outer contour of the force-applying end 232, which drives the slide bar 222 and the material support plate 223 to move synchronously, thereby removing the obstruction of the placement groove 130. At the same time, the slide bar 222 on the other side, under the elastic force of the spring 217, drives the material support plate 223 to move to the position that obstructs the placement groove 130, preventing the product from falling off.

[0056] After the flipping is completed, the product remains stably in the flipped position thanks to the coordinated action of all components, which facilitates subsequent inspection or processing operations.

[0057] In summary, by setting up the flipping mechanism 200, not only can the product to be tested be automatically prevented from falling off when driving the positioning carrier 120, the placement slot 130 and the product to be tested to flip without adding an extra cylinder, but it can also avoid the problems of complex, bulky and space-consuming traditional cylinder flipping mechanisms, as well as the problem of small impacts generated by mechanical buffering at the end of the cylinder. This achieves the effect of ensuring the compactness of the mechanism and the stability of the flipping process while avoiding damage to brittle components.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
