Description

Technical Field

[0001] This utility model relates to the field of mobile phone case processing technology, specifically a general-purpose jig for mobile phone case processing. Background Technology

[0002] A general-purpose jig for mobile phone case processing is a special tool used to assist in the processing of mobile phone cases. Its core function is to ensure processing accuracy, improve production efficiency, and guarantee product quality by fixing, supporting, positioning, or adsorbing mobile phone cases, while adapting to the needs of different models, sizes, and processing techniques.

[0003] Existing universal jigs for mobile phone case processing often have a single, unadjustable positioning structure for the phone case during the processing. When processing irregularly shaped phone cases, it is necessary to adjust the positioning structure multiple times to make it compatible with the original, which can easily lead to positional deviation of the phone case during processing, thus affecting the processing accuracy. In addition, traditional jigs can only produce one product, which also reduces the efficiency of the structure.

[0004] Therefore, those skilled in the art have provided a universal fixture for processing mobile phone cases to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a universal fixture for processing mobile phone cases, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A universal fixture for processing mobile phone cases includes a base plate with multiple slots on its surface. Each slot contains a matching insert block. A bracket is fixedly connected to the top of each insert block. A main fixture is mounted on the top of the bracket. A positioning mechanism is located on the top of the main fixture. The positioning mechanism includes a positioning frame on the top of the main fixture. A positioning threaded hole is formed in the top of the positioning frame. A positioning post is rotatably connected inside the positioning threaded hole. A foolproof post is fixedly connected to one side of the positioning threaded hole. An elastic sleeve is fitted around the foolproof post. The side surface of the foolproof post... The positioning post is equipped with an axial marking line and an annular anti-slip texture on its top. By rotating the positioning post, its height and position can be precisely adjusted, enabling accurate positioning of the phone case. This ensures that the phone case is fixed in position during processing, improving processing accuracy and product quality. The anti-fooling post effectively prevents the phone case from being placed in the wrong orientation, avoiding processing errors and product damage caused by incorrect orientation. The elastic sleeve acts as a buffer when the phone case is placed, reducing collisions and wear. Furthermore, the axial marking line provides a more intuitive way for operators to determine whether the phone case is placed in the correct orientation, further improving the accuracy and convenience of operation.

[0008] As a further embodiment of this utility model: a vacuum plate is fixedly connected to the bottom of the main fixture, and a vacuum interface is provided on the top of the vacuum plate and connected to the bottom of the main fixture through the vacuum interface. A vacuum pipe is provided inside the vacuum plate. When the vacuum equipment is started, a negative pressure is formed in the vacuum pipe, and the phone case is tightly adsorbed onto the surface of the main fixture through the corresponding air passage on the main fixture. This adsorption method can provide uniform and strong adsorption force. Compared with traditional mechanical clamps, it can fix the phone case more firmly. Especially for some complex-shaped, smooth-surfaced or thin-walled phone cases, it can effectively prevent them from shifting or shaking due to cutting forces, vibrations and other factors during processing, and ensure the stability of processing.

[0009] As a further improvement of this utility model: one end of the vacuum pipe is connected to an air inlet, and the other end of the vacuum pipe is fixedly connected to a vacuum pump. A valve is installed on the outside of the vacuum pipe. During the processing, by adjusting the opening of the valve, the vacuum level in the vacuum pipe can be stabilized, ensuring that the phone case is subjected to a stable and appropriate adsorption force. This helps to reduce the movement or vibration of the phone case caused by fluctuations in adsorption force, thereby improving processing accuracy and product quality.

[0010] As a further improvement of this utility model: connecting blocks are fixedly connected to both sides of the vacuum plate, a swing cylinder is fixedly connected to one side of the connecting block, a connecting joint is fixedly connected to one side of the swing cylinder, and a vacuum pipe is fixedly connected to one end of the connecting joint. Since mobile phone cases come in various shapes, some with complex curved surfaces or special structures, traditional fixed adsorption fixtures cannot guarantee comprehensive and stable adsorption. However, by using the swing cylinder, the vacuum plate can be adjusted to the optimal adsorption angle according to the actual shape of the mobile phone case and processing requirements, so that the vacuum adsorption force is evenly applied to the surface of the mobile phone case, which greatly improves the stability and accuracy of adsorption and effectively avoids displacement or shaking of the mobile phone case due to uneven force during processing, thereby ensuring processing accuracy.

[0011] As a further improvement of this utility model: the output end of the swing cylinder is fixedly connected to an installation block, one side of the installation block is fixedly connected to a telescopic pressure claw, and the bottom of the telescopic pressure claw is fixedly connected to a hydraulic support rod. The swing cylinder can drive the installation block to rotate and swing, so that the telescopic pressure claw can approach and press the phone case from different angles. Through the swing design, the telescopic pressure claw can be adjusted to the optimal pressing angle according to the actual shape of the phone case, ensuring that the phone case is firmly and accurately positioned during the processing, reducing processing errors caused by inaccurate positioning.

[0012] As a further improvement of this utility model: the top of the main fixture is uniformly provided with vacuum adsorption holes around the positioning frame. The vacuum adsorption holes are connected to the vacuum pipes inside the vacuum plate. The connection surface between the vacuum plate and the main fixture is provided with an annular sealing groove. A rubber sealing ring is provided inside the sealing groove. The uniformly distributed vacuum adsorption holes enable the vacuum adsorption force to act evenly on the surface of the phone case, avoiding displacement or shaking of the phone case during processing due to insufficient local adsorption force. This greatly improves the stability of adsorption. Moreover, the simultaneous operation of multiple vacuum adsorption holes can quickly reduce the air pressure in the adsorption area, forming a strong vacuum adsorption force, so that the phone case is tightly adsorbed in a short time, improving production efficiency.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The height and position of the rotating positioning pin can be precisely adjusted, enabling accurate positioning of the phone case and ensuring its fixed position during processing. This improves processing accuracy and product quality. The anti-misalignment pin effectively prevents incorrect placement of the phone case, avoiding processing errors and product damage caused by misalignment. The elastic sleeve acts as a buffer when the phone case is placed, reducing collisions and wear. Furthermore, the axial marking line provides a more intuitive way for operators to determine if the phone case is placed correctly, further improving the accuracy and convenience of operation.

[0015] 2. When the vacuum equipment is started, a negative pressure is formed in the vacuum pipeline. The phone case is tightly adsorbed onto the surface of the main fixture through the corresponding air passage on the main fixture. This adsorption method can provide uniform and strong adsorption force. Compared with traditional mechanical clamps, it can fix the phone case more firmly. Especially for some complex-shaped, smooth-surfaced or thin-walled phone cases, it can effectively prevent them from shifting or shaking due to cutting forces, vibrations and other factors during processing, and ensure the stability of processing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Reference Figure 1 - Figure 5This embodiment provides a universal fixture for processing mobile phone cases, including a base plate 1. Multiple slots 2 are formed on the surface of the base plate 1, and each slot 2 contains a corresponding insert block 3. A bracket 4 is fixedly connected to the top of the insert block 3. A main fixture 5 is mounted on the top of the bracket 4, and a positioning mechanism 6 is mounted on the top of the main fixture 5. The positioning mechanism 6 includes a positioning frame 601, which is located on the top of the main fixture 5. A positioning threaded hole 602 is formed on the top of the positioning frame 601. A positioning post 603 is rotatably connected inside the positioning threaded hole 602. An anti-foolproof post 604 is fixedly connected to one side of the positioning threaded hole 602. An elastic sleeve 605 is fitted around the anti-foolproof post 604. The side surface of the anti-foolproof post 604 is provided with… An axial marking line 606 is provided. The top of the positioning post 603 is provided with annular anti-slip texture 607. A vacuum plate 7 is fixedly connected to the bottom of the main fixture 5. A vacuum interface 8 is provided on the top of the vacuum plate 7 and is connected to the bottom of the main fixture 5 through the vacuum interface 8. A vacuum pipe 9 is provided inside the vacuum plate 7. One end of the vacuum pipe 9 is connected to an air inlet 10, and the other end of the vacuum pipe 9 is fixedly connected to a vacuum pump 11. A valve 12 is installed on the outside of the vacuum pipe 9. Connecting blocks 13 are fixedly connected to both sides of the vacuum plate 7. A swing cylinder 14 is fixedly connected to one side of the connecting block 13. A connecting connector 15 is fixedly connected to one side of the swing cylinder 14. One end of the connecting connector 15 is fixedly connected to the vacuum pipe 9. The output of the swing cylinder 14... An installation block 16 is fixedly connected to one end of the installation block 16. A telescopic pressure claw 17 is fixedly connected to one side of the installation block 16. A hydraulic support rod 18 is fixedly connected to the bottom of the telescopic pressure claw 17. Before processing the phone case, adjustments need to be made according to the size and hole parameters of the phone case to be processed. By rotating the positioning pin 603, the height of the positioning pin 603 extending out of the positioning frame 601 is adjusted by utilizing its threaded connection with the positioning threaded hole 602, so that the top of the positioning pin 603 matches the depth of the positioning hole of the phone case. At the same time, according to the width of the phone case, the fixing structure between the insert 3 and the slot 2 is loosened, and the position of the insert 3 in the slot 2 is adjusted, thereby changing the position of the bracket 4 and the main fixture 5, ensuring that the fixture as a whole corresponds to the work position of the processing equipment. After the adjustment is completed, Re-fix the insert block 3. For the telescopic pressure claw 17, its extension length can be adjusted via the hydraulic support rod 18 to ensure that the pressure claw can accurately act on the edge of the phone case, meeting the clamping requirements of phone cases of different sizes. During processing, the operator picks up the phone case and observes the axial marking line 606 on the side surface of the anti-misalignment post 604. According to the marking line, the anti-misalignment hole on the phone case is aligned with the anti-misalignment post 604. Since the anti-misalignment post 604 is fitted with an elastic sleeve 605, the elastic sleeve 605 plays a buffering and guiding role during the phone case insertion process, avoiding rigid collision between the phone case and the anti-misalignment post 604, and ensuring that the anti-misalignment hole is accurately fitted into the anti-misalignment post 604, achieving initial error prevention positioning. Subsequently, the positioning hole on the phone case is aligned with the positioning post 603.The annular anti-slip texture 607 on the top of the positioning post 603 increases the friction with the inner wall of the positioning hole, making it less likely for the phone case to slip during insertion. It can slide smoothly along the positioning post 603 until the bottom of the phone case contacts the top of the positioning frame 601, completing the initial positioning of the phone case. At this time, the vacuum pump 11 is started and the valve 12 is opened. The vacuum pump 11 draws air from the air inlet 10 through the vacuum pipe 9, creating a negative pressure inside the vacuum plate 7. The negative pressure is transmitted to the main fixture 5 through the vacuum interface 8, and then acts on the bottom of the phone case, firmly adhering the phone case to the main fixture 5, preventing the phone case from shifting during processing. At the same time, the swing cylinder 14 is connected to the air source through the connecting joint 15 and starts working. The output end of the swing cylinder 14 drives the mounting block 16 and the telescopic pressure claw 17 to swing downward. When the telescopic pressure claw 17 swings above the edge of the phone case, the hydraulic support rod 18 pushes the telescopic pressure claw 17 downward. 7 extends downwards, allowing the bottom of the telescopic pressure claw 17 to contact the surface of the phone case and apply pressure, further pressing the phone case. Under the combined action of vacuum adsorption and the clamping force of the telescopic pressure claw 17, the phone case is stably fixed on the fixture, providing a reliable clamping effect for subsequent processing. After processing, valve 12 and vacuum pump 11 are closed, the negative pressure inside vacuum plate 7 gradually disappears, the vacuum adsorption effect is released, the swing cylinder 14 reverses its operation, driving the telescopic pressure claw 17 to swing upwards and reset, the hydraulic support rod 18 retracts, causing the telescopic pressure claw 17 to move away from the surface of the phone case, and the operator can easily remove the processed phone case, completing one processing cycle. If different specifications of phone cases need to be processed, the quick-change structure of the main fixture 5 allows for easy replacement of the appropriate main fixture 5, and readjustment of components such as the positioning post 603 and the telescopic pressure claw 17 to meet the processing requirements of the new specifications of phone cases.

[0025] Example 2

[0026] Reference Figure 1 - Figure 5This embodiment is based on the previous embodiment, but differs in that vacuum adsorption holes 19 are evenly distributed around the positioning frame 601 on the top of the main fixture 5. These vacuum adsorption holes 19 are connected to the vacuum pipes 9 inside the vacuum plate 7. An annular sealing groove 20 is formed on the connection surface between the vacuum plate 7 and the main fixture 5. A rubber sealing ring 21 is installed inside the sealing groove 20. When the phone case completes its initial positioning, i.e., its bottom contacts the top of the positioning frame 601, the vacuum pump 11 is started and the valve 12 is opened. The vacuum pump 11 draws air through the vacuum pipes 9, creating a negative pressure inside the vacuum plate 7. At this time, the negative pressure inside the vacuum plate 7 is transmitted to the top of the main fixture 5 through the connected vacuum adsorption holes 19. Because the vacuum adsorption holes 19 are evenly distributed around the positioning frame 601, adsorption force can be applied from multiple points on the bottom of the phone case, making the force on the bottom of the phone case more even and preventing the edges of the phone case from lifting due to insufficient local adsorption force. Simultaneously, a rubber sealing ring 21 is installed inside the annular sealing groove 20 on the connection surface between the vacuum plate 7 and the main fixture 5. The rubber sealing ring 21 undergoes elastic deformation under the compression of both, filling the gap between the sealing groove 20 and the connecting surface to form a reliable sealing barrier. This sealing structure effectively prevents external air from seeping in through the connection gap between the vacuum plate 7 and the main fixture 5, ensuring that the negative pressure inside the vacuum plate 7 will not decrease due to leakage, allowing the vacuum adsorption holes 19 to maintain sufficient adsorption force to firmly fix the phone case on the main fixture 5. During processing, the continuous sealing effect of the rubber sealing ring 21 ensures the stability of the vacuum environment. Even if the processing equipment vibrates, it can prevent air leakage from affecting the adsorption effect. The evenly distributed vacuum adsorption holes 19 can cope with the small deformation of the phone case caused by the processing force. By balancing the stress through multi-point adsorption, it prevents the phone case from shifting or deforming during processing, further ensuring processing accuracy. After processing is completed, the valve 12 and the vacuum pump 11 are closed, the negative pressure inside the vacuum plate 7 gradually disappears, and the adsorption force of the vacuum adsorption holes 19 weakens simultaneously until it is completely released.
