Description

Technical Field

[0001] This utility model relates to the field of repair equipment technology, specifically a workbench for mobile phone repair. Background Technology

[0002] With the rapid iteration of smartphone technology, mobile phones have evolved from simple communication tools into intelligent devices integrating high-definition screens, complex motherboards, and precision sensors. As the lifespan of these devices extends and repair costs rise, the mobile phone repair market continues to expand. Repair scenarios such as individual repair shops and brand after-sales service outlets are increasingly demanding professional repair equipment. During the repair process, mobile phones need to be stably fixed to prevent displacement during disassembly, soldering, screen separation, and other operations. At the same time, tools such as screwdrivers, tweezers, and hot air guns need to be conveniently stored to ensure repair efficiency and operational safety. Therefore, a functionally compatible and easy-to-use repair workbench has become a key piece of equipment for improving repair quality.

[0003] Upon inspection, Chinese patent application number CN201821814082.3 was found to disclose a mobile phone repair workbench, including a workbench support, a collection drawer, a column, a storage cabinet, a repair table, a repair equipment table, a shelf, a writing board, and casters. The collection drawer, storage cabinet, and repair table are located on top of the workbench support. The repair table is positioned above the collection drawer and storage cabinet, and a column is located above the repair table. A lighting tube and a writing board are fixedly connected to the upper end of the column. This utility model adds a storage cabinet, a repair equipment table, a rubber insulating pad, and various plug-in panels for repair electrical components. The added rubber insulating pad can protect the mobile phone during repair, preventing scratches. The camera can record video of the repair process, and the lighting tube provides illumination.

[0004] However, this technical solution does not disclose the specific method of fixing the mobile phone, and only relies on the flat support of the workbench. During the repair, the mobile phone is prone to slipping due to external force, resulting in secondary damage such as screen scratches and motherboard solder joint detachment. Especially for irregularly shaped models such as curved screens and foldable screens, there is a lack of adaptable fixing structure, which cannot meet the stable fixing requirements of mobile phones of different shapes. It is necessary to use external equipment, which increases the space occupied by the repair equipment and the cost of use. Therefore, a workbench for mobile phone repair is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a workbench for mobile phone repair, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone repair workbench, including a repair table surface. The repair table surface has multiple sets of suction grooves, and suction cups are provided in the suction grooves for adsorbing and fixing mobile phones. A cylinder is fixedly installed at the bottom of the repair table surface, and an air pipe is fixedly installed at the end of the cylinder near the suction cup. The air pipe and the suction cup are interconnected, and each set of air pipes is connected to two sets of suction cups. A piston block is provided in the cylinder for pumping air out of the cylinder. A piston rod is fixedly connected to the side of the piston block away from the air pipe. The piston rod is L-shaped, and the other end of the piston rod passes through the repair table surface. A sliding block is fixedly connected to its end for moving the piston rod. A fixing ring corresponding to the sliding block is fixedly installed on the repair table surface, and the sliding block is slidably connected to the side wall of the fixing ring. A locking mechanism is provided on the side wall of the fixing ring for limiting the position of the sliding block after movement.

[0007] By adopting the above technical solution, it can flexibly adapt to mobile phones of different sizes. The flexible adsorption of the suction cup avoids the damage to the body caused by traditional clamping. The connection structure between the cylinder and the air tube ensures efficient and stable air extraction and release. The L-shaped piston rod cleverly realizes the conversion of force direction. With the sliding connection between the sliding block and the fixed ring, the air extraction and release operation is more effortless and smooth. The locking mechanism can lock in time after the sliding block is in place to prevent adsorption failure due to accidental contact during maintenance. The overall structure takes into account adaptability, ease of operation and fixed reliability, which greatly improves the stability and efficiency of mobile phone maintenance.

[0008] Furthermore, a metal pressure plate is fixedly installed at the bottom of the maintenance platform by bolts to fix the position of the cylinder.

[0009] By adopting the above technical solution, the cylinder is prevented from shifting due to the vibration caused by the piston block movement during the air extraction and release process, ensuring that the connection and sealing between the air pipe and the suction cup are not affected.

[0010] Furthermore, the locking mechanism is slidably mounted on the side wall of the fixed ring away from the cylinder. The locking mechanism includes a spring and a positioning block. One end of the spring is fixedly connected to the inner wall of the fixed ring, and the other end is fixedly connected to the side wall of the positioning block. The positioning block is slidably mounted on the inner wall of the fixed ring, and the side of the positioning block near the cylinder is arc-shaped. When the sliding block moves, the side wall of the sliding block contacts and pushes the positioning block to slide towards the inner wall of the fixed ring.

[0011] By adopting the above technical solution, the locking mechanism can automatically avoid obstacles without the need for additional manual operation of the positioning block, thus improving the ease of operation.

[0012] Furthermore, the sliding block has a positioning groove on its side wall that corresponds to the positioning block, and two sets are symmetrically arranged. When the sliding block moves and drives the piston rod to be in the air extraction state, the positioning block and the positioning groove work together to limit the position of the sliding block.

[0013] By adopting the above technical solution, displacement of the sliding block due to accidental contact or vibration is effectively prevented, ensuring a stable negative pressure state in the cylinder, thereby ensuring that the suction cup's adsorption and fixation effect on the mobile phone is uninterrupted, forming a stable mechanical locking structure that eliminates the need for manual alignment and adjustment, thus simplifying the operation process.

[0014] Furthermore, a pressure block is slidably mounted on the top of the sliding block, and a connecting rod is fixedly connected to the bottom of the pressure block. A transmission block corresponding to the positioning groove is slidably mounted on the bottom of the sliding block, and the end of the transmission block away from the connecting rod is adjacent to the positioning block. The connecting rod has a V-shaped design, and the inclined surface at the bottom of the connecting rod corresponds to the corners of the two sets of transmission blocks, which is used to release the locking of the sliding block and the fixing ring.

[0015] By adopting the above technical solution, the V-shaped structure of the connecting rod can simultaneously convert the vertical downward force of the pressure block into the horizontal outward thrust of the two sets of transmission blocks, realizing the linkage effect of one-button double push. There is no need to operate the two sets of transmission blocks separately. In addition, the inclined surface at the bottom of the connecting rod can reduce the frictional resistance with the corners of the transmission blocks, making the thrust transmission smoother and reducing jamming.

[0016] In summary, the present invention has the following main advantages: This invention utilizes a cylinder to create negative pressure on the suction cup, using atmospheric pressure to drive the flexible suction cup to deform and adhere to the back of the phone. It eliminates the need for traditional mechanical clamps and is compatible with phones of various shapes and thicknesses, including flat, curved, and foldable screens. This effectively avoids uneven force distribution that could cause body deformation and screen damage, reducing the risk of secondary damage. The entire operation is mechanical; simply pushing the sliding block completes the suction and suction, while pressing the block to unlock releases the air. The process is simple, intuitive, and requires no electricity, reducing limitations caused by electronic component failures and lowering maintenance costs, thus improving repair efficiency. The spring and positioning block locking mechanism within the fixing ring automatically engage with the positioning groove when the sliding block reaches the suction position, ensuring continuous negative pressure on the suction cup and preventing accidental phone detachment. Furthermore, unlocking requires actively pressing the block to trigger the transmission structure, further ensuring operational safety. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Example 1 A mobile phone repair workbench, such as Figure 1-6As shown, the device includes a repair workbench 1 with multiple suction slots 2. These slots can flexibly accommodate mobile phones or tablets of different sizes, improving the versatility of the suction area. Each suction slot 2 contains a suction cup 3 for attaching and securing the phone. The flexible contact of the suction cup 3 avoids causing hard damage to the phone's surface. A cylinder 5 is fixedly installed at the bottom of the workbench 1, serving as the power source for air extraction and discharging. The cylinder 5 has a stable structure and uniform output force. An air pipe 31 is fixedly installed at the end of the cylinder 5 near the suction cup 3, connecting to the suction cup 3 to form a complete airflow channel. This allows multiple suction points to work simultaneously, enhancing the stability of the phone's fixation. Each air pipe 31 connects to two suction cups 3, and each air pipe 31 is operated by different sliding blocks 4, allowing for separate operation of the suction areas without affecting each other. A piston block 52 is installed inside the cylinder 5 for extracting and discharging air. The precise fit of the piston block 52 ensures the accuracy of air pressure regulation within the cylinder 5. A piston rod 43 is fixedly connected to the side of the piston block 52 away from the air pipe 31. The piston rod 43 has an L-shaped design, which cleverly changes the direction of force transmission, saving installation space under the worktable. The other end of the piston rod 43 passes through the maintenance worktable 1, and a sliding block 4 is fixedly connected to its end for moving the piston rod 43, achieving linkage between the upper and lower components of the worktable. A fixing ring 42 corresponding to the sliding block 4 is fixedly installed on the maintenance worktable 1. The fixing ring 42 provides a stable guide trajectory for the sliding block 4, ensuring no deviation during movement. The sliding block 4 is slidably connected to the side wall of the fixing ring 42. This sliding engagement makes operation smoother and less strenuous. A locking mechanism is provided on the side wall of the fixing ring 42 to limit the position of the sliding block 4 after movement. The locking mechanism can quickly lock after the sliding block 4 moves into place, preventing accidental movement from affecting the adsorption effect.

[0024] Please see Figure 1-6 The bottom of the maintenance platform 1 is fixed with a metal pressure plate 51 by bolts to fix the position of the cylinder 5. The metal pressure plate 51 has excellent anti-deformation ability and can form a stable clamp on the cylinder 5, preventing the cylinder 5 from shifting due to vibration caused by the movement of the piston block 52 during the air extraction and release process, and ensuring that the connection and sealing between the air pipe 31 and the suction cup 3 are not affected.

[0025] Please see Figure 1-6The locking mechanism is slidably mounted on the side wall of the fixed ring 42 away from the cylinder 5. This mounting position allows for timely locking after the sliding block 4 completes its suction stroke, preventing the locking action from interfering with the adsorption operation. The locking mechanism includes a spring 421 and a positioning block 422. The spring 421 provides a continuous restoring force, ensuring that the positioning block 422 always has a locking tendency. The positioning block 422 serves as the core locking component, providing a limiting function. One end of the spring 421 is fixedly connected to the inner wall of the fixed ring 42, and the other end is fixedly connected to the side wall of the positioning block 422, allowing the spring force to act directly on the positioning block 422, resulting in high transmission efficiency. The positioning block 422... The positioning block 422 is slidably installed on the inner wall of the fixed ring 42. The sliding fit structure ensures that the positioning block 422 moves smoothly without jamming, avoiding locking failure due to jamming. The side of the positioning block 422 near the cylinder 5 is arc-shaped. The arc surface can convert the lateral thrust of the sliding block 4 into the radial displacement of the positioning block 422, reducing the frictional resistance when the two are in contact. This makes it easier for the sliding block 4 to push the positioning block 422. When the sliding block 4 moves, the side wall of the sliding block 4 contacts and pushes the positioning block 422 to slide towards the inner wall of the fixed ring 42. The locking mechanism can automatically avoid the position without additional manual operation of the positioning block 422, improving the convenience of operation.

[0026] Please see Figure 1-6 The sliding block 4 has a positioning groove 401 on its side wall that corresponds to the positioning block 422. The size of the positioning groove 401 is precisely matched with that of the positioning block 422 to ensure a good fit when they are in contact, and to avoid any loose gaps. Two sets of positioning grooves 401 are symmetrically arranged. The two sets of positioning grooves 401 are located on both sides of the sliding block 4 to achieve precise positioning of the sliding block 4 in its working state. When the sliding block 4 moves and drives the piston rod 43 into the suction state, the positioning block 422 and the positioning groove 401 work together to limit the position of the sliding block 4, effectively preventing the sliding block 4 from being displaced due to accidental contact or vibration, ensuring the stability of the negative pressure state in the cylinder 5, and thus ensuring that the suction cup 3 does not interrupt the adsorption and fixation effect on the mobile phone, forming a stable mechanical locking structure. No manual alignment and adjustment are required, simplifying the operation process.

[0027] Please see Figure 1-6A pressure block 41 is slidably mounted on the top of the sliding block 4, and a connecting rod 411 is fixedly connected to the bottom of the pressure block 41. The connecting rod 411 and the pressure block 41 are integrally injection molded, with high structural strength and not easy to break, ensuring stable transmission of the pressing action. A transmission block 402 corresponding to the positioning groove 401 is slidably mounted on the bottom of the sliding block 4, and the end of the transmission block 402 away from the connecting rod 411 is adjacent to the positioning block 422, shortening the transmission path and making the unlocking action more responsive and avoiding delay. The connecting rod 411 has a V-shaped design, and the V-shaped structure of the connecting rod 411 can synchronously convert the vertical downward force of the pressure block 41 into two sets of transmission blocks 402. The horizontal outward pushing force achieves a one-button double-push linkage effect, eliminating the need to operate the two sets of transmission blocks 402 separately. The bottom slope of the connecting rod 411 reduces the frictional resistance with the corners of the transmission blocks 402, making the force transmission smoother and reducing jamming. The bottom slope of the connecting rod 411 corresponds to the corners of the two sets of transmission blocks 402, which is used to release the lock of the sliding block 4 and the fixing ring 42. The slope angle is precisely matched with the corners of the transmission blocks 402, ensuring that the force can be efficiently transmitted to the transmission blocks 402. The entire unlocking process can be completed by simply pressing the pressure block 41. The operation is simple and convenient, without the need for additional tools, greatly improving the flexibility of maintenance operations.

[0028] The working principle of this utility model is as follows: When it is necessary to fix the mobile phone, the mobile phone is placed on the suction cup 3 position on the repair table 1, and the sliding block 4 is pushed to move away from the suction cup 3 along the side wall of the fixing ring 42. The L-shaped piston rod 43 moves synchronously with the sliding block 4, which drives the piston block 52 in the cylinder 5 to move synchronously away from the suction cup 3, so that a negative pressure is formed inside the cylinder 5. The cylinder 5 is fixed in position by the metal pressure plate 51, and the air in the suction cup 3 is extracted through the air pipe 31. The suction cup 3 deforms under the action of external atmospheric pressure and tightly adheres to the back of the mobile phone, thereby achieving the adsorption and fixation of the mobile phone. As the sliding block 4 moves to the end of the fixed ring 42 away from the suction cup 3, the side wall of the sliding block 4 first contacts the arc-shaped surface of the positioning block 422 and generates a pushing force on it, causing the positioning block 422 to slide towards the inner wall of the fixed ring 42. At the same time, the spring 421 is compressed and deformed and stores energy. When the sliding block 4 moves to the end of the fixed ring 42, the positioning groove 401 of the sliding block 4 aligns with the positioning block 422 in the fixed ring 42. Under the elastic force of the spring 421, the positioning block 422 is stuck into the positioning groove 401, restricting the movement of the sliding block 4 and ensuring that the suction cup 3 continues to maintain a negative pressure adsorption state. To remove the phone, press the pressure block 41 on top of the sliding block 4. The pressure block 41 moves the connecting rod 411 downward. The inclined surface at the bottom of the connecting rod 411 pushes the two sets of transmission blocks 402 to slide outward. The transmission block 402 squeezes the positioning block 422, causing it to compress the spring 421 and exit the positioning groove 401, thus releasing the locked state. Then, push the sliding block 4 to move closer to the suction cup 3. The piston rod 43 drives the piston block 52 to move closer to the suction cup 3 in sync. The air pressure in the cylinder 5 is restored, and outside air enters the suction cup 3 through the air pipe 31. The suction cup 3 elastically rebounds to its initial state, the suction force disappears, and the phone can be removed.
