Description

Technical Field

[0001] The utility model relates to the field of grinding machines, in particular to a display glass plane grinding machine. Background Art

[0002] Mobile phone display glass surface grinder is a machine specially used for grinding mobile phone display glass. The main function of this equipment is to make the surface of mobile phone display glass smoother and flatter through grinding, polishing and other processes to improve its light transmittance and display effect. Mobile phone display glass surface grinder is usually composed of grinding disc, grinding liquid supply system, pressure control system, motor and other parts. During the grinding process, the grinding disc will rotate and apply a certain pressure. At the same time, the grinding liquid will be continuously supplied to the grinding disc to play a role of cooling and lubrication. By adjusting parameters such as grinding time, grinding liquid concentration, grinding disc speed, etc., the grinding effect and processing efficiency can be controlled.

[0003] During the use of the current grinder, the upper grinding assembly relies on the top cylinder to control its longitudinal position movement so as to work together with the lower grinding assembly. In the existing matching technology, the upper grinding assembly and the lower grinding assembly are usually matched by the engagement of the keyway and the key block. However, this traditional engagement method requires that the keyway and the key block must be strictly aligned on the same axis for engagement, which brings considerable challenges in actual operation. The operator needs to manually adjust the rotation position of the upper grinding assembly to ensure that the keyway and the key block are correctly aligned, and then use the cylinder as a power source to slowly mate the upper grinding assembly with the lower grinding assembly. This cumbersome alignment step not only affects the ease of use of the grinder, but also significantly reduces the efficiency of glass grinding. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a display glass plane grinding machine to solve the more cumbersome alignment operation in traditional operations, reduce the convenience of using the grinder, and reduce the technical problems of the grinder's efficiency in grinding glass.

[0005] To achieve the above object, the utility model provides the following technical solutions: a display glass plane grinding machine, comprising a device body and a support frame, a lower grinding assembly is arranged on the top of the device body, the lower grinding assembly comprises a retaining ring and a transmission block, a guide mechanism is arranged on the outer side of the transmission block, the guide mechanism comprises a card slot, and guide slots are formed on both sides of the card slot;

[0006] The support frame is provided with a cylinder, the telescopic end of the cylinder is rotatably provided with an upper grinding assembly, the upper grinding assembly comprises a supporting plate and a pressure plate, a through slot is provided at the central axis of the pressure plate, and a guide wheel is provided on the inner wall of the through slot.

[0007] By adopting the above technical solution, the cylinder is used as the power source to accurately control the longitudinal position movement of the upper grinding assembly. During the gradual descent of the upper grinding assembly, the guide wheel located on the inner side of the through groove will contact the guide groove. Thanks to the inclined structural design of the guide groove, it can effectively guide the guide wheel to ensure that it moves smoothly along the predetermined path.

[0008] Furthermore, the guide groove is an inclined structure for providing a movement track of the guide wheel, and the clamping groove and the guide wheel are engaged with each other.

[0009] By adopting the above technical solution, the inclined structural design of the guide groove plays a vital role in the operation of the machine. It not only provides a clear and accurate motion trajectory for the guide wheel, but also ensures that the upper grinding assembly can be stably and smoothly docked with the lower grinding assembly during the descent process. Through the clever guidance of the inclined structure, the guide wheel can move along the optimal path, thereby minimizing possible deviations and frictions, and improving the accuracy and reliability of the overall mechanical operation.

[0010] Furthermore, the clamping slots and guide wheels are provided in plurality and are arranged in an equidistant ring shape along the central axis of the transmission block.

[0011] By adopting the above technical solution, the connection stability and alignment accuracy between the upper grinding assembly and the lower grinding assembly are significantly enhanced. The cooperation of multiple slots and guide wheels means that during the operation of the grinder, there are more contact points to ensure a tight connection between the two components, thereby effectively preventing the problem of falling off or misalignment that may be caused by single-point contact.

[0012] Furthermore, a protective plate is provided between the supporting plate and the pressing plate to block the through groove from external dust.

[0013] By adopting the above technical solution, the protective plate arranged between the support plate and the pressure plate plays an important protective role. It effectively blocks the through groove from external dust and prevents dust and other impurities from entering the through groove, thereby avoiding problems such as jamming or wear of the guide wheel that may be caused by interference from impurities.

[0014] Furthermore, a liquid collecting tank is arranged on the outer side of the supporting plate, and a dust shield is arranged on the outer side of the pressing plate, so as to isolate the grinding machine from external dust.

[0015] By adopting the above technical solution, the liquid collecting tank arranged on the outside of the support plate collects the grinding liquid during the grinding process, effectively preventing the splashing of the grinding liquid, keeping the working area of ​​the grinder clean, avoiding the waste of grinding liquid, and improving resource utilization.

[0016] Furthermore, the material of the protective plate is transparent acrylic, which is used to provide a user with an observation point for the working status at the through slot position.

[0017] By adopting the above technical solution, the user can intuitively observe the working status at the through groove position, providing a convenient observation point. The user can understand the internal operation of the grinder in real time without disassembling or moving other parts, thereby more accurately grasping the grinding progress and effect.

[0018] Furthermore, a liquid guide pipe is provided at the bottom of the liquid collecting tank, and the liquid guide pipe passes through the dust shield through the mounting hole.

[0019] By adopting the above technical solution, the liquid guide pipe arranged at the bottom of the liquid collecting tank can effectively guide and control the grinding liquid to flow from the liquid collecting tank to the grinding working area, ensuring that the grinding liquid can be evenly and continuously supplied to the grinding working area, thereby maintaining stability and consistency during the grinding process.

[0020] Furthermore, an inner gear ring is arranged on the inner side of the retaining ring, and an outer gear ring is arranged on the outer side of the transmission block. A plurality of freewheels are meshed between the inner gear ring and the outer gear ring, and a plurality of grinding tool grooves are arranged on the surface of the freewheel.

[0021] By adopting the above technical solution, multiple free-wheels are meshed between the inner gear ring inside the retaining ring and the outer gear ring outside the transmission block, making the transmission during the grinding process more stable and reliable. Under the joint action of the inner and outer gear rings, the free-wheel can achieve uniform and stable rotational motion, thereby ensuring the uniformity and consistency of the grinding effect.

[0022] Furthermore, a lower grinding disc is arranged at the bottom of the floating wheel, and an upper grinding disc is arranged at the bottom surface of the pressure plate.

[0023] By adopting the above technical solution, the lower grinding disc arranged at the bottom of the center wheel and the upper grinding disc arranged on the bottom surface of the pressure plate cooperate with each other to form an effective grinding area, so that the grinding material can be fully ground and processed between the upper and lower grinding discs, thereby improving the grinding efficiency and quality.

[0024] Furthermore, the lower grinding disc and the upper grinding disc are both in a detachable connection structure.

[0025] By adopting the above technical solutions, it means that they can be easily installed and replaced, which greatly simplifies the maintenance and repair process of the grinder and reduces the related costs.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model uses a guide mechanism. As the upper grinding assembly descends, the guide wheel inside it will contact the guide groove on the lower grinding assembly. The inclined surface structure of the guide groove guides the guide wheel to ensure that the guide wheel can move along the correct path. At the same time, this guiding effect continues until the guide wheel is accurately guided to the slot position and engages with the slot, eliminating the need for manual tedious alignment of the upper grinding assembly and the lower grinding assembly in traditional grinding machines, thereby improving the convenience of the grinding machine and further improving the grinding efficiency of the grinding machine for glass;

[0028] 2. The utility model provides a protective plate and a dust shield, and utilizes the protective plate to protect the through groove, thereby effectively preventing external dust from falling into the matching gap between the through groove and the transmission block, ensuring the cleanliness of the inside of the grinding mechanism, and avoiding the interference of dust on the grinding process, thereby improving the grinding accuracy and stability. At the same time, the provision of the dust shield further enhances the dustproof ability of the grinder, and it effectively blocks external dust or impurities from entering the internal grinding mechanism through the gap between the upper grinding assembly and the lower grinding assembly, providing a cleaner environment for the grinding process, which not only enhances the protectiveness of the grinding mechanism, but also significantly improves the grinding effect on the glass, ensuring the stability and reliability of the grinding quality.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A display glass surface grinding machine, such as Figure 1-Figure 4 As shown, it includes a device body 1 and a support frame 2. A lower grinding assembly 3 is arranged on the top of the device body 1. The lower grinding assembly 3 includes a retaining ring 301 and a transmission block 303. A guide mechanism 6 is arranged on the outer side of the transmission block 303. The guide mechanism 6 includes a card slot 601. Guide slots 602 are formed on both sides of the card slot 601.

[0038] A cylinder 4 is provided on the support frame 2, and an upper grinding assembly 5 is rotatably provided at the telescopic end of the cylinder 4. The upper grinding assembly 5 includes a supporting plate 501 and a pressure plate 503. A through slot 504 is provided at the central axis of the pressure plate 503, and a guide wheel 603 is provided on the inner wall of the through slot 504. The cylinder 4 is used as a power source to accurately control the longitudinal position movement of the upper grinding assembly 5. In the process of gradual descent of the upper grinding assembly 5, the guide wheel 603 located on the inner side of the through slot 504 will contact the guide slot 602. Thanks to the inclined structural design of the guide slot 602, it can effectively guide the guide wheel 603 to ensure that it moves smoothly along a predetermined path. As the upper grinding assembly 5 continues to descend, the guide wheel 603 will eventually be accurately guided to the position of the slot 601, thereby achieving a close engagement with the slot 601, eliminating the cumbersome alignment and matching steps in traditional operations, so that the upper grinding assembly 5 and the lower grinding assembly 3 can be quickly and accurately docked.

[0039] See also Figure 2 , Figure 4 The guide groove 602 is an inclined structure, which is used to provide a motion trajectory for the guide wheel 603. The slot 601 and the guide wheel 603 are engaged with each other. The inclined structure design of the guide groove 602 plays a vital role in the operation of the machine. It not only provides a clear and accurate motion trajectory for the guide wheel 603, but also ensures that the upper grinding assembly 5 can be stably and smoothly docked with the lower grinding assembly 3 during the descent process. Through the clever guidance of the inclined structure, the guide wheel 603 can move along the optimal path, thereby minimizing possible deviations and frictions, and improving the accuracy and reliability of the overall mechanical operation. At the same time, the engagement mechanism between the slot 601 and the guide wheel 603 not only enhances the connection stability between the upper grinding assembly 5 and the lower grinding assembly 3, but also effectively prevents accidental falling off or dislocation during the grinding process.

[0040] See also Figure 2 , Figure 4 There are multiple slots 601 and guide wheels 603, which are arranged in an equidistant ring along the central axis of the transmission block 303, which significantly enhances the connection stability and alignment accuracy between the upper grinding assembly 5 and the lower grinding assembly 3. The cooperation of multiple slots 601 and guide wheels 603 means that during the operation of the grinding machine, there are more contact points to ensure the tight connection between the two components, thereby effectively preventing the problem of falling off or misalignment caused by single-point contact. At the same time, the equidistant ring arrangement not only ensures the uniform distribution of the contact points, but also facilitates the smooth rotation of the upper grinding assembly 5 and the lower grinding assembly 3.

[0041] Embodiment 2:

[0042] See also Figure 1 , Figure 2 A protective plate 7 is provided between the support plate 501 and the pressure plate 503 for isolating the through slot 504 from external dust.

It effectively isolates the through slot 504 from external dust, and prevents dust and other impurities from entering the through slot 504, thereby avoiding problems such as jamming or wear of the guide wheel 603 caused by interference from impurities. At the same time, the provision of the protective plate 7 also improves the overall cleanliness and service life of the grinder. By reducing the erosion of dust on internal parts, the protective plate 7 helps to maintain the grinder in good working condition and reduces the extra cost and time consumption caused by cleaning and maintenance.

[0043] See also Figure 1 , Figure 2 A liquid collecting tank 502 is arranged on the outer side of the supporting plate 501, and a dust shield 506 is arranged on the outer side of the pressure plate 503, which are used to isolate the grinder from external dust. The liquid collecting tank 502 arranged on the outer side of the supporting plate 501 collects the grinding liquid during the grinding process, effectively preventing the splashing of the grinding liquid, keeping the working area of ​​the grinder clean, and also avoiding the waste of grinding liquid, thereby improving resource utilization. At the same time, the dust shield 506 on the outer side of the pressure plate 503 plays a key role in preventing external dust from entering the interior of the grinder. Through the setting of this barrier, the working environment inside the grinder can be kept clean, thereby reducing the influence of dust on the grinding effect and machine parts.

[0044] See also Figure 1 , Figure 2The material of the protective plate 7 is transparent acrylic, which is used to provide the user with an observation point for the working status at the position of the through slot 504, so that the user can intuitively observe the working status at the position of the through slot 504, providing a convenient observation point. The user can understand the internal operation of the grinder in real time without disassembling or moving other parts, so as to more accurately grasp the grinding progress and effect. At the same time, the transparent acrylic material also has good durability and impact resistance, which can ensure that the protective plate 7 remains clear and transparent during long-term use and is not easily damaged or deformed. This not only extends the service life of the protective plate 7, but also reduces the maintenance cost caused by frequent replacement.

[0045] See also Figure 1 , Figure 2 A liquid guide tube 508 is provided at the bottom of the liquid collecting tank 502, and the liquid guide tube 508 passes through the dust shield 506 through the mounting hole 507.

Under the joint action of the inner and outer gear rings 304, the freewheel 306 can realize uniform and stable rotational motion, thereby ensuring the uniformity and consistency of the grinding effect. At the same time, the plurality of grinding tool grooves 307 provided on the surface of the freewheel 306 further improve the grinding efficiency. These grinding tool grooves 307 not only increase the contact area between the freewheel 306 and the grinding material, but also can effectively bring the grinding material into the grinding area during the rotation process, thereby accelerating the grinding process.
