Description

Technical Field

[0001] The utility model belongs to the technical field of clamping devices, and in particular relates to a positioning fixture for surface treatment of 3C products. Background Art

[0002] The positioning fixture used for 3C product surface treatment is a tooling device specially designed for the precise positioning and stable clamping of 3C products (such as mobile phones, tablets, cameras and other consumer electronic products) during surface treatment processes (such as polishing, spraying, electroplating, etc.). Through precise design and manufacturing, it ensures that 3C products can be accurately positioned in the predetermined position during the treatment process, avoiding uneven treatment caused by deviation or shaking.

[0003] In the existing technology, the original surface treatment positioning fixtures are mostly based on traditional square or rectangular product designs. Their clamping structure and positioning method are relatively fixed, and they are difficult to adapt to 3C products with strange shapes and non-standard sizes. As a result, when processing these new products, the fixtures cannot provide stable and precise positioning and clamping, affecting the quality and efficiency of surface treatment.

[0004] Therefore, a positioning fixture for surface treatment of 3C products is proposed, which has a multi-directional clamping and positioning structure and can clamp and position 3C products by adaptively adjusting the clamping angle, thereby solving the limitations in clamping engineering. Utility Model Content

[0005] In order to overcome the problem that the clamping structure and positioning method of existing positioning clamping tools are relatively fixed and difficult to adapt to 3C products with strange shapes and non-standard sizes.

[0006] The technical solution of the utility model is: a positioning fixture for surface treatment of 3C products, comprising a base plate; a frame is fixedly connected to the upper end of the base plate, screws are rotatably provided on the inner walls of the left and right ends of the frame, two screw sleeves are threadedly installed on the screws, the front and rear outer walls of the screw sleeves are fitted with the front and rear inner walls of the frame, the right end of the screw is fixedly connected to a rocker, a blanking assembly is provided on the screw sleeve, and the blanking assembly comprises a first fixed column and a second fixed column; the upper end of the screw sleeve is fixedly connected to the first fixed column, the upper end of the first fixed column is fixedly connected to the second fixed column, and a clamping assembly is provided on the upper end of the second fixed column.

[0007] Preferably, when it is necessary to clamp irregular 3C products, the rocker is rotated to make the two screw sleeves approach each other on the screw rod, and then the object is placed in the clamping assembly for clamping and rotation. When the surface treatment work is completed, the rocker is rotated to make the two screw sleeves move away from each other, so that the object on the clamping assembly falls into the blanking assembly for collection.

[0008] Preferably, the unloading assembly includes a connecting frame and a unloading net; the connecting frame is fixed to the outside of the first fixed column, and a unloading net is fixed to one end of the two connecting frames close to each other. The unloading net installed on the connecting frame can be used to take over the items that have been processed later.

[0009] Preferably, the clamping assembly includes a first fixed block, a synchronous motor, a rotating column, a second fixed block, an electromagnetic device and a shell; the upper end of the second fixed column is fixedly connected to the first fixed block, the ends of the two first fixed blocks away from each other are fixedly connected to the synchronous motor, the output shafts of the two synchronous motors are both facing the upper center of the base plate, the output shafts of the synchronous motor pass through the first fixed block and are fixedly connected to the rotating column, the ends of the two rotating columns close to each other are fixedly connected to the second fixed block, the ends of the two second fixed blocks close to each other are fixedly connected to the electromagnetic device, and the side outer wall of the electromagnetic device is fixedly connected to the shell, and by turning on the synchronous motor, the output shaft of the synchronous motor can drive the second fixed block on the rotating column to rotate, which is convenient for rotation adjustment and auxiliary surface treatment after clamping.

[0010] Preferably, the rear end of the first fixed block is fixedly connected to the first limit block, and the rear end of the shell is fixedly connected to the second limit block. A correction bar is slidingly provided on the two first limit blocks and the second limit blocks. Since the second fixed block is rotatably provided on the rotating column, when performing the clamping work, it is necessary to ensure that the two shells are on the same horizontal plane. By inserting the correction bar into the two first limit blocks and the second limit blocks, the two shells can be in the same horizontal plane. Then, the object is placed in the close end of the two shells, and then the rocker is rotated to drive the clamping components on the two screw sleeves for clamping, and then the correction bar is taken out from the two first limit blocks and the second limit blocks.

[0011] Preferably, the clamping assembly includes a trough body, a magnetic block, a clamping column and a limit ring; the ends of the two shells that are close to each other are penetrated by a uniformly distributed trough body, and the inner wall of the trough body is movably provided with a magnetic block, and the ends of the magnetic block and the electromagnetic device that are close to each other repel each other, and the ends of the two magnetic blocks that are close to each other are fixedly connected to the clamping column, and the outer wall of the magnetic block is fixedly connected to the limit ring. When it is necessary to perform surface treatment on irregular products, the product is placed in the end of the two shells that are close to each other, and then the rocker is rotated to drive the two screw sleeves close to each other. Since the ends of the magnetic block and the electromagnetic device that are close to each other repel each other, the repulsive force generated causes some of the clamping columns among the multiple clamping columns to be concave according to the shape of the product, so that the clamping columns can clamp the irregular-shaped products.

[0012] Preferably, the ends of the two limiting rings that are close to each other are fitted with the ends of the two shell inner walls that are close to each other. The outer diameter of the limiting ring is 1 cm longer than the radius of the groove body. The limiting ring serves as a limiting structure to prevent the magnetic block and the electromagnetic device from repelling each other, causing the magnetic block to slip out of the groove body due to the lack of an intercepting block.

[0013] Preferably, the blanking net is made of a flexible material with a certain degree of ductility, and the tension of the blanking net surface can be adjusted by following the movement of the two screw sleeves.

[0014] Beneficial effects of the utility model:

[0015] 1. By placing the product on one end of the two shells close to each other, and then rotating the rocker to drive the two screw sleeves closer to each other, the magnetic block and the electromagnetic device repel each other. The repulsive force generated causes some of the multiple clamping columns to be concave according to the shape of the product, so that the clamping columns can clamp irregularly shaped products, solving the problem of inconvenience in clamping irregular 3C products.

[0016] 2. The blanking net installed on the connecting frame can be used to receive items that have been processed later. The blanking net is made of flexible material and has a certain degree of ductility. The tension of the blanking net surface can be adjusted by following the movement of the two screw sleeves.

[0017] 3. By inserting the correction bar into the two first limit blocks and the second limit blocks, the two shells can be placed in the same horizontal plane. Then put the object into the end close to the two shells, and then rotate the rocker to drive the clamping components on the two screw sleeves to clamp. Then remove the correction bar from the two first limit blocks and the second limit blocks, so that the two shells can be leveled. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-Figure 3 In this embodiment, the blanking assembly includes a connecting frame 103 and a blanking net 104; the connecting frame 103 is fixed to the outside of the first fixed column 101, and a blanking net 104 is fixed to one end of the two connecting frames 103 close to each other, and the blanking net 104 is made of flexible material.

[0026] See also Figure 4In this embodiment, the clamping assembly includes a first fixed block 201, a synchronous motor 202, a rotating column 203, a second fixed block 204, an electromagnetic device 205 and a shell 206; the upper end of the second fixed column 102 is fixedly connected to the first fixed block 201, and the ends of the two first fixed blocks 201 that are away from each other are fixedly connected to the synchronous motor 202. The output shafts of the two synchronous motors 202 are both directed to the upper center of the bottom plate 1. The output shafts of the synchronous motors 202 pass through the first fixed block 201 and are fixedly connected to the rotating column 203. The ends of the two rotating columns 203 that are close to each other are fixedly connected to the second fixed block 204. The ends of the two second fixed blocks 204 that are close to each other are fixedly connected to the electromagnetic device 205. The side outer wall of the electromagnetic device 205 is fixedly connected to the shell 206. The rear end of the first fixed block 201 is fixedly connected to the first The limiting block 6 and the rear end of the shell 206 are fixedly connected to the second limiting block 7, and the two first limiting blocks 6 and the second limiting blocks 7 are slidingly provided with a correction strip 8, and the clamping assembly includes a groove body 207, a magnetic block 208, a clamping column 209 and a limiting ring 210; the ends of the two shells 206 that are close to each other are penetrated by evenly distributed grooves 207, and the inner walls of the groove bodies 207 are movably provided with magnetic blocks 208, and the magnetic blocks 208 and the ends of the electromagnets 205 that are close to each other repel each other, and the ends of the two magnetic blocks 208 that are close to each other are fixed with the clamping column 209, and the outer walls of the magnetic blocks 208 are fixed with the limiting ring 210, and the ends of the two limiting rings 210 that are close to each other are fitted with the ends of the inner walls of the two shells 206 that are close to each other, and the outer diameter of the limiting ring 210 is 1 cm longer than the radius of the groove body 207.

[0027] During operation, the rocker 5 is rotated to move the two screw sleeves 4 closer to each other on the screw rod 3, thereby moving the two first fixing columns 101 and the second fixing columns 102 closer to each other;

[0028] When performing the clamping operation, it is necessary to ensure that the two shells 206 are on the same horizontal plane.

Then, the correction bar 8 is removed from the two first limit blocks 6 and the second limit block 7.

[0030] Through the above steps, when it is necessary to clamp irregular 3C products, the two screw sleeves 4 are moved closer to each other on the screw rod 3 by rotating the rocker 5, and then the items are placed in the clamping assembly for clamping and rotation. When the surface treatment is completed, the two screw sleeves 4 are moved away from each other by rotating the rocker 5, so that the objects on the clamping assembly fall into the blanking assembly for collection. The clamping assembly solves the problem that the clamping structure and positioning method of the existing positioning clamping tools are relatively fixed, and are difficult to adapt to 3C products with odd shapes and non-standard sizes.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
