AI Technical Summary
Traditional positioning fixtures have poor product positioning flexibility, especially when changing models, the position of the clamping blocks needs to be adjusted, resulting in long changeover times, complex structures, and high costs.
Four fixed side baffles are used in conjunction with the first and second positioning clamps to form an L-shaped placement position. The clamps are driven by the first and second side push cylinders to move the product, so as to achieve horizontal or vertical positioning and simplify the product changeover process.
It improves positioning flexibility, shortens changeover time, reduces costs, and expands the applicability of the equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated positioning technology, specifically a universal mobile phone mid-frame positioning mechanism. Background Technology
[0002] With the development of the times and technology, automated production is becoming more and more widespread. Automation refers to the use of various control systems, mechanical equipment, computers and information technology in the production and service industries to reduce or eliminate manual operation and realize the automatic operation of the production process. Automation technology can improve production efficiency, quality, safety and repeatability, while reducing costs and human error. When automating material picking, positioning fixtures are usually used to facilitate material picking in place.
[0003] However, most traditional positioning fixtures currently only position products horizontally or vertically, which is not very flexible. In addition, the center position of the positioning fixture is relatively fixed. When changing the model of different products, the position of the clamping block needs to be adjusted, which results in a long changeover time. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a universal mobile phone mid-frame positioning mechanism, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a universal mobile phone mid-frame positioning mechanism, including a mounting base plate, a placement plate being provided on the surface of the mounting base plate via a support plate, a first side-push cylinder and a second side-push cylinder being provided at the bottom of the placement plate, a first positioning clamping block and a second positioning clamping block being provided at the driving ends of the first side-push cylinder and the second side-push cylinder respectively, and four fixed side baffles being provided on the surface of the placement plate.
[0006] Optionally, the bottom of the mounting base plate is provided with a connecting side plate for connecting the equipment.
[0007] Optionally, a reinforcing rib is also provided between the mounting base plate and the connecting side plate.
[0008] Optionally, the four fixed side baffles are arranged in pairs at an angle on the placement plate.
[0009] Optionally, the first positioning clamp and the second positioning clamp are also positioned at an angle to each other at the edge of the placement plate.
[0010] Optionally, the surface of the support plate is provided with mounting elongated holes for adjustment.
[0011] This utility model provides a universal mobile phone mid-frame positioning mechanism, which has the following beneficial effects:
[0012] This universal mobile phone frame positioning mechanism uses four fixed side baffles combined with a first positioning clamp and a second positioning clamp to form an L-shaped placement position. It can simultaneously accommodate horizontal or vertical product positioning, expanding the scope of application of the mechanism and improving positioning flexibility. At the same time, the first and second side push cylinders work together to drive the corresponding first and second positioning clamps to push the product to the side for positioning. No adjustment of the clamp positions is required when changing models, which has the advantage of short changeover time. Moreover, the structure is relatively simple and the cost is low.

Second positioning clamp; 9. Connecting side plate; 10. Reinforcing rib; 11. Mounting elongated hole. Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Please see Figure 1 This utility model provides a technical solution: a universal mobile phone mid-frame positioning mechanism, including a mounting base plate 1, a connecting side plate 9 for connecting the device is provided at the bottom of the mounting base plate 1, and a reinforcing rib 10 is provided between the mounting base plate 1 and the connecting side plate 9. The mechanism can be fixed to the side of the device through the connecting side plate 9, and a positioning platform is formed, which effectively saves the device installation area.
[0017] The surface of the mounting base plate 1 is provided with a placement plate 3 via a support plate 2. The surface of the support plate 2 is provided with an adjustment mounting elongated hole 11. The bottom of the placement plate 3 is provided with a first side-push cylinder 4 and a second side-push cylinder 7. The driving ends of the first side-push cylinder 4 and the second side-push cylinder 7 are respectively provided with a first positioning clamp 5 and a second positioning clamp 8. The first positioning clamp 5 and the second positioning clamp 8 are also positioned at a 90-degree angle at the edge of the placement plate 3. When the product is placed on the placement plate 3 by the robotic arm, depending on whether the product is placed horizontally or vertically, the first side-push cylinder 4 and the second side-push cylinder 7 work together to drive the corresponding first positioning clamp 5 and the second positioning clamp 8 to push the product inward. The product is positioned relative to the four fixed side baffles 6 and their edges, allowing it to be reshaped. There is no need to adjust the position of the clamps; only the driving distance of the first side-push cylinder 4 and the second side-push cylinder 7 needs to be adjusted. This achieves a short-time reshaping, and the structure is relatively simple and the cost is low.
[0018] The surface of the placement plate 3 is provided with four fixed side baffles 6. The four fixed side baffles 6 are arranged in pairs at a 90-degree angle on the placement plate 3. The four fixed side baffles 6, together with the first positioning clamp 5 and the second positioning clamp 8, form an L-shaped placement position on the placement plate 3. This allows the mechanism to be compatible with both horizontal and vertical products, expanding the scope of application of the mechanism and improving the positioning flexibility of the mechanism.
[0019] In this invention, the working steps of the device are as follows:
[0020] The mechanism can be fixed to the side of the equipment by connecting the side plate 9, and then automatically pick up the material with the help of the robotic arm, placing the product horizontally or vertically on the placement position on the placement plate 3.
[0021] Then, the first side-push cylinder 4 drives the first positioning clamp 5 to push the product inward, and then the second side-push cylinder 7 similarly drives the second positioning clamp 8 to push the product inward, so as to position it against the edge of the fixed side baffle 6, and then take it to the next station with the help of the material picking device.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
