[0002] Nowadays, mobile phone frames are all made of metal. The mobile phone frame consists of top and bottom frames and left and right frames. Since the top and bottom frames are irregularly shaped, the existing technology usually uses a clamping method to clamp the left and right sides of the frame. The clamping cylinder clamps the sides of the mobile phone frame, which has poor positioning effect. It is impossible to guarantee that the clamping position of each mobile phone frame is uniform in each processing, which affects the processing accuracy of the product. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a positioning carrier for processing mobile phone parts, which solves the problem that poor positioning accuracy affects the processing accuracy of mobile phone frames.

[0004] The technical solution of this utility model to achieve the above objectives is a positioning carrier for processing mobile phone parts, comprising:

[0005] A reference plate, which is used for reference positioning of the end of the product to be processed;

[0006] At least two positioning pins are used to position the two ends of the same side of the product to be processed;

[0007] A central positioning mechanism includes a sliding plate that can slide horizontally and at least one positioning element disposed on the sliding plate for positioning the middle part of the product to be processed on the side away from the positioning post. The positioning element can move closer to or away from the positioning post under the action of the sliding plate.

[0008] An end positioning mechanism includes a horizontally sliding mounting plate and at least one positioning pin on the mounting plate for positioning the end of the product to be processed away from the reference plate. The sliding direction of the mounting plate is perpendicular to the sliding direction of the sliding plate, and the mounting plate and the sliding plate are in an inclined fit. The mounting plate can approach the reference plate under the action of preload, and the sliding plate can control the mounting plate to move away from the reference plate when sliding.

[0009] Preferably, the positioning vehicle further includes:

[0010] The base plate, the sliding plate and the mounting plate are both slidably connected to the base plate;

[0011] A limiting plate is mounted on the base plate, and a mounting plate is located between the base plate and the limiting plate. The limiting plate has clearance holes to facilitate the movement of the mounting plate.

[0012] A fixing plate is mounted on the base plate on the side away from the limiting plate, and a reference plate is mounted on the fixing plate.

[0013] Furthermore, the base plate has a first guide groove for guiding the sliding plate to move and a second guide groove for guiding the mounting plate to move, and the first guide groove and the second guide groove are connected.

[0014] Furthermore, a baffle is provided on one side of the base plate, and an active space is formed between the baffle, the base plate and the limiting plate to facilitate the sliding of the mounting plate.

[0015] Preferably, the end positioning mechanism further includes a connecting plate connected to the mounting plate and a roller rotatably connected to the connecting plate. The roller can roll relative to the guide ramp on the sliding plate to control the mounting plate away from the reference plate.

[0016] Preferably, the sliding plate has a mounting groove, the positioning member is slidably connected to the slide rail fixed in the mounting groove via a slider, a guide rod is provided on one side of the sliding plate, the positioning member is slidably connected to the guide rod, and an elastic element for applying preload to the positioning member is sleeved on the guide rod.

[0017] Furthermore, a limiting groove is formed on one side of the sliding plate, the guide rod passes through the limiting groove, one end of the elastic member abuts against the positioning member, and the other end abuts against the inner wall of the limiting groove.

[0018] Preferably, a pressure plate and a fixing block are respectively provided on both sides of the base plate, one end of the sliding plate has an inclined surface and the other end is provided with a guide rod, the sliding plate passes through the pressure plate from below, and the guide rod is interlocked with the fixing block.

[0019] Preferably, each of the limiting plate and the fixing plate is provided with a pad to elevate the product to be processed.

[0020] Preferably, one side of the positioning element has a positioning plane, which can contact the plane of the product to be processed.

[0021] Its advantages over existing technologies are:

[0022] In this invention, the reference plate can position the ends of the product. The positioning element in the middle positioning mechanism can cooperate with the two positioning pins to achieve three-point positioning, clamping the two sides of the product. Simultaneously, the positioning pin in the end positioning mechanism can hold the other end of the product against the reference plate, clamping both ends of the product. When the sliding plate slides horizontally, the vertical distance between the positioning element and the positioning pin bracket increases, loosening the two sides of the product. The sliding plate and the mounting plate are in a beveled fit; as the sliding plate slides, it presses against the mounting plate, causing the mounting plate to move away from the reference plate. The positioning pin also moves synchronously, loosening the two ends of the product. After a new product to be processed is placed in, the mounting plate, under the preload, slides towards the reference plate, simultaneously pressing against the sliding plate, causing it to slide in the opposite direction. The positioning element cooperates with the two positioning pins, and the positioning pin cooperates with the reference plate, re-clamping the two sides and two ends of the product to be processed, ensuring uniform front-to-back position and a stronger positioning effect, facilitating subsequent precision machining of the product.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figure 1 and Figure 2 As shown, a preferred embodiment of this utility model proposes a positioning carrier for processing mobile phone parts. The positioning carrier mainly includes components such as a base plate 5, a reference plate 1, a middle positioning mechanism 2, an end positioning mechanism 3, a limiting plate 6, and a fixing plate 7. It positions and clamps the mobile phone frame 13 to be processed through a three-point positioning method so as to perform fine processing on the mobile phone frame 13.

[0032] like Figure 1 As shown, the limiting plate 6 and the fixing plate 7 are respectively installed at both ends of the upper part of the base plate 5. The middle positioning mechanism 2 is located between the limiting plate 6 and the fixing plate 7 and is horizontally slidably connected to the base plate 5. A baffle 8 is installed at the end of the base plate 5 where the limiting plate 6 is located. The baffle 8, the base plate 5, and the limiting plate 6 enclose an active space. The end positioning mechanism 3 is located within this active space and is horizontally slidably connected to the base plate 5.

[0033] The positioning device can simultaneously position multiple mobile phone frame 13 to be processed.

[0034] refer to Figure 4 , Figure 6 The middle positioning mechanism 2 mainly consists of a sliding plate 21, a guide rod 23, and multiple positioning components 22. The end positioning mechanism 3 mainly consists of a mounting plate 31, a connecting plate 34, rollers 33, and multiple positioning pins 32.

[0035] refer to Figures 2-3 A first guide groove 501 and a second guide groove 502 are formed on the base plate 5, and the first guide groove 501 and the second guide groove 502 are connected by a through groove, so that the overall shape of the guide groove is "I". Slide rails are installed in both the first guide groove 501 and the second guide groove 502, and the slide rails in the two guide grooves are perpendicular to each other. The sliding plate 21 is slidably connected to the slide rail in the first guide groove 501 via a slider, and the mounting plate 31 is slidably connected to the slide rail in the second guide groove 502 via a slider. Therefore, the sliding directions of the sliding plate 21 and the mounting plate 31 are perpendicular to each other.

[0036] A baffle 8 is positioned horizontally on one side of the second guide groove 502 to stop the mounting plate 31. A clearance groove is provided on the limiting plate 6, through which the upper end of the mounting plate 31 passes. The clearance groove provides clearance and allows sufficient space for the mounting plate 31 to move. Multiple positioning pins 32 are horizontally fixed sequentially to the upper end of the mounting plate 31, with a certain distance between adjacent positioning pins 32.

[0037] The connecting plate 34 is connected to the middle area of ​​the bottom of the mounting plate 31, and the roller 33 is rotatably connected to the front end of the connecting plate 34, which cooperates with the second guide slope 2141 on the sliding plate 21.

[0038] refer to Figure 1 The reference plate 1 is fixedly mounted on the fixing plate 7, away from the positioning pin 32. The side of the reference plate 1 closest to the positioning pin 32 is a vertical plane, used for aligning and positioning the ends of multiple mobile phone frame frames 13 to be processed. In other words, the reference plate 1 ensures that the ends of multiple mobile phone frame frames 13 to be processed are flush. The positioning pin 32 is used to position the other end of the mobile phone frame frame 13 to be processed. The reference plate 1 and the positioning pin 32 cooperate to clamp both ends of the mobile phone frame frame 13.

[0039] like Figure 6 As shown, each positioning pin 32 has a retractable pin 321 at its front end. The pin 321 is subjected to the preload of the spring inside the positioning pin 32, which allows the pin 321 to hold the end of the phone frame 13 in place. Since the pin 321 is retractable, it can prevent the pin 321 from damaging the phone frame 13.

[0040] like Figure 2 As shown, two guide rods 12 are provided on the baffle 8. The guide rods 12 are interlocked with the mounting plate 31 and serve as guides. A spring (not shown in the figure) is fitted on each guide rod 12. The spring applies a preload to the mounting plate 31, so that the mounting plate 31 always slides in the direction of the reference plate 1.

[0041] like Figure 4 , Figure 5 As shown, a mounting groove 212 is provided in the middle area of ​​the upper part of the sliding plate 21. A slide rail is installed in the mounting groove 212, and multiple positioning elements 22 are slidably connected to the slide rail by sliders. Multiple limiting grooves 213 are provided on one side of the sliding plate 21, and the limiting grooves 213 correspond one-to-one with the positioning elements 22. The guide rod 23 passes through the multiple limiting grooves 213 in sequence, and both ends of the guide rod 23 are fixed to the sliding plate 21. One side of the positioning element 22 is slidably connected to the guide rod 23. A small spring 24 is provided in each limiting groove 213. The small spring 24 is sleeved on the guide rod 23, and both ends of the small spring 24 abut against the inner wall of the positioning element 22 and the limiting groove 213, respectively. The small spring 24 plays a buffering role to prevent the positioning element 22 from damaging the product.

[0042] refer to Figure 4 The positioning part 22 has a vertically upward protrusion on one side of the upper part of the positioning part 22 to form a positioning part 221. One side of the positioning part 221 has a positioning plane 2211. When the positioning part 22 clamps the product, the positioning plane 2211 contacts the plane on the product and plays a positioning role when clamping the product.

[0043] refer to Figure 5 There is a notch 214 on the side of the sliding plate 21 away from the guide rod 23. The notch 214 has a second guide slope 2141. The roller 33 at the front end of the connecting plate 34 can roll relative to the second guide slope 2141.

[0044] like Figure 2 As shown, a pressure plate 10 and a fixing block 9 are respectively provided at both ends of the first guide groove 501. The pressure plate 10 and the fixing block 9 are both fixedly installed on the limiting plate 6 and the fixing plate 7 by screws. Two guide rods 12 are provided at one end of the sliding plate 21. These two guide rods 12 are inserted and connected to the limiting plate 6 to guide the sliding of the sliding plate 21.

[0045] like Figure 1 As shown, a row of positioning pins 4 is provided on both the limiting plate 6 and the fixing plate 7. The spacing between any two adjacent positioning pins 4 is equal, and the positioning pins 4 on the limiting plate 6 correspond one-to-one with the positioning pins 4 on the fixing plate 7. The positioning pins 4 and the positioning pins 32 are staggered left and right. The positioning pins 4 are used to position the two ends of the same side of the product, and the positioning pins 22 position the other side of the product. The three together form a three-point positioning system.

[0046] like Figure 4 As shown, at the other end of the sliding plate 21 (i.e. the end away from the guide rod 12), there is a first guide slope 211, which in this embodiment extends downward at an angle.

[0047] When the pressing mechanism presses upward against the first guide slope 211, the sliding plate 21 can slide along the first guide groove 501 towards the fixed block 9 under the action of the first guide slope 211. The pressure plate 10 acts as a downward pressure to prevent the sliding plate 21 from tilting upward.

[0048] Because the pressure is applied from bottom to top, space can be saved on the left and right sides. In other technical solutions, the first guide slope 211 can also extend from left to right or from right to left, so that horizontal pressure on the slope can also control the sliding plate 21 to slide.

[0049] Under the action of the spring, the roller 33 is always in contact with the second guide slope 2141 on one side of the sliding plate 21. When the sliding plate 21 slides in the direction of the fixed block 9, the second guide slope 2141 will squeeze the roller 33. This causes the mounting plate 31 to slide away from the reference plate 1. At this time, the vertical distance between the positioning member 22 and the corresponding two positioning posts 4 increases, so that the mobile phone frame 13 to be processed can be placed on the positioning member 22.

[0050] After the phone frame 13 is placed on the positioning member 22, the pressing mechanism disengages from the sliding plate 21. The mounting plate 31 moves towards the reference plate 1 under the action of the spring. Simultaneously, the roller 33 presses against the second guide slope 2141 on the sliding plate 21, causing the sliding plate 21 to move away from the fixing block 9. The vertical distance between the positioning member 22 and the corresponding two positioning pins 4 decreases, and the two positioning pins 4 cooperate with the positioning member 22 to clamp the two sides of the phone frame 13. At the same time, as the positioning pin 32 moves towards the reference plate 1, it presses against the end of the phone frame 13, aligning the other end of the phone frame 13 under the action of the reference plate 1. In this way, multiple phone frames 13 can be positioned and clamped using this fixture, and the positional accuracy of all phone frames 13 is consistent, facilitating subsequent precision machining.

[0051] When the sliding plate 21 slides in the direction of the fixed block 9, the positioning piece 22 and the positioning pin 32 move synchronously, releasing the phone frame 13, and the phone frame 13 can be removed.

[0052] To ensure the balance of both ends of the phone frame 13, a pad 11 is installed on both the limiting plate 6 and the fixing plate 7. The upper surface of the pad 11 is flush with the upper surface of the positioning component 22 body to ensure that the front and rear ends of the phone frame 13 are at the same height and achieve balance.

[0053] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
