[0003] However, the clamp mounting station of the existing diamond wire cutting machine is arranged in the machine box, and this design causes obvious defects in the clamp feeding and discharging process: before the glass sheet is processed, the operator needs to clamp the glass sheet on the clamp one by one, then carries the clamp with the glass sheet into the machine box of the wire cutting machine, and accurately installs it on the corresponding mounting station; after the processing is completed, the clamp needs to be disassembled from the machine box and taken out one by one. On the one hand, the space in the machine box of the diamond wire cutting machine is small, and is integrated with cutting mechanisms, transmission assemblies and other structural components, when the clamp is installed or disassembled one by one, the hands and tools of the operator are easy to interfere with the internal structural components, not only need to frequently adjust the operation posture to avoid the interference components, which causes the feeding and discharging process to be time-consuming and laborious, and seriously reduces the overall processing efficiency; on the other hand, during the interference process, the clamp may collide with the equipment structural components or the glass sheet may collide with the clamp, which not only causes the glass sheet to be damaged and the clamp to be deformed, but also may cause the hands of the operator to be cut by the structural components, and there is a great safety hazard.

DETAILED DESCRIPTION

[0038] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0039] Embodiment: a clamp feeding and discharging mechanism and a diamond wire cutting machine, like Figure 1 , 3As shown, the diamond wire cutting machine includes a machine body 1 and a clamp feeding and discharging mechanism 4. The machine body 1 is internally provided with a lifting platform 3, and is integrated with a diamond wire cutting mechanism, a cooling system, a control system and other conventional components. The lifting platform 3 is provided with a clamp mounting station at the bottom, and the machine body 1 is provided with a feeding port 2 on one side. The cutting mechanism is used to realize the high-speed movement of the diamond wire and complete the cutting of the glass sheet 5; the cooling system is used to cool the cutting area during the cutting process to prevent the glass sheet 5 from breaking due to high temperature, and to carry away the cutting debris; the control system can realize the automatic control of the whole cutting process, further improving the processing efficiency and operation safety. The diamond wire cutting mechanism, the cooling system, the control system and other conventional components are prior art, so their specific structure and working principle will not be repeated here.

[0040] As shown in Figures 1-6 The clamp feeding and discharging mechanism 4 includes an intermediate plate 42, a lifting assembly 43 and a lifting vehicle 41. The intermediate plate 42 is used as a bearing and transferring core component of the clamp 6, and includes a plate body 421, a plurality of rectangular grooves 423 for bearing the clamp 6 are formed on the plate body 421, the number of the grooves 423 is consistent with the number of the clamp mounting stations in the diamond wire cutting machine, and the positions of the grooves 423 correspond to the mounting stations one by one, so as to ensure that each clamp 6 can be accurately matched to the target mounting station through the groove 423. The lifting assembly 43 is used to drive the intermediate plate 42 and the clamp 6 to realize lifting, and then to complete the accurate butt joint of the clamp 6 and the mounting station. The shape profile of the plate body 421 is consistent with that of the lifting plate 31, and both are rectangular structures. The lifting assembly 43 includes a driving member 431 and a connecting rod 432, the connecting rod 432 is slidably connected with both sides of the plate body 421, so as to make the intermediate plate 42 slide out of or slide into the machine body 1 of the diamond wire cutting machine, and the driving member 431 is used to drive the connecting rod 432 to move up and down, and then to drive the intermediate plate 42 and the clamp 6 thereon to move up and down synchronously.

[0041] In the above technical solution, for the traditional diamond wire cutting machine, the clamp 6 needs to be carried to the machine box interior installation station one by one, and needs to be repeatedly adjusted to adapt to the station, and needs to be operated back and forth multiple times for single feeding and discharging, which is time-consuming. The intermediate plate 42 realizes the batch synchronization of clamp 6 bearing and transfer through the one-to-one corresponding structure design of the multi-slot hole 423: on the one hand, the number and position of the slot hole 423 on the plate body 421 of the intermediate plate 42 are completely matched with the installation station in the diamond wire cutting machine, and the operator can place multiple clamps 6 in the slot hole 423 at one time in the external operation area, without the need to check the station position one by one, thereby shortening the clamping preparation time; on the other hand, the intermediate plate 42 can drive all clamps 6 to be transferred synchronously, replacing the traditional single-clamp 6 single-carrying mode, thereby greatly reducing the transfer times of the clamps 6 between the outside and the inside of the machine box. Therefore, the present application can realize the purpose of simultaneous feeding and discharging of multiple clamps 6 by placing multiple clamps 6 in the corresponding slot hole 423 outside the machine body 1, and then moving the intermediate plate 42 to the inside of the machine body 1 to align the installation station.

[0042] In addition, for the traditional diamond wire cutting machine, the operator needs to manually lift and adjust the clamp 6 in the narrow machine body 1 to realize the butt joint of the clamp 6 and the installation station, which not only has high labor intensity, but also is difficult to accurately control the height, and is prone to butt joint deviation. The lifting assembly 43 converts the labor-intensive operation into mechanical precise driving: the connecting rod 432 and the plate body 421 of the intermediate plate 42 are slidingly fitted on both sides to enable the intermediate plate 42 to smoothly enter the machine body 1 through the feeding port 2; the driving part 431 can provide stable driving force to drive the connecting rod 432 and the intermediate plate 42 to precisely lift, without the need for manual lifting. The operator only needs to control the driving part 431 to complete the height butt joint of the clamp 6 and the installation station, thereby reducing the labor intensity. The pre-assembly and transfer of the clamp 6 are completed outside the diamond wire cutting machine, and the operator does not need to enter the machine body 1 of the complex diamond wire cutting machine, thereby avoiding the risk of interference with the internal structural parts, effectively preventing the problems of operator injury, glass sheet 5 breakage and clamp deformation, greatly improving the safety, and solving the problems of time-consuming and labor-intensive feeding and discharging of the clamp in the existing diamond wire cutting machine and poor safety.

[0043] Preferably, the connecting rod 432 is provided with two connecting rods 432, and the two connecting rods 432 are respectively located on opposite sides of the plate body 421, and each connecting rod 432 is matched with two driving parts 431 arranged in front and back. In this way, the transverse stress of the plate body 421 can be balanced, and the plate body 421 is prevented from being laterally deviated due to excessive stress on one side; on the other hand, the two driving parts 431 on a single connecting rod 432 act synchronously in front and back, which can ensure that the connecting rod 432 stably lifts in the vertical direction, and prevents the connecting rod 432 from turning over or tilting due to uneven stress in front and back.

[0044] Preferably, the connecting rod 432 and the plate body 421 slide through the cooperation of the sliding groove 422 and the pulley 433.

[0045] Further preferably, in the present embodiment, the plate body 421 is provided with a sliding groove 422 on both sides, the connecting rod 432 and the sliding groove 422 are arranged in parallel and opposite to each other, and one end of the connecting rod 432 is rotatably connected with a pulley 433 for cooperation with the sliding groove 422. The wheel diameter of the pulley 433 is equivalent to the width of the sliding groove 422, ensuring that the pulley 433 can smoothly slide in the sliding groove 422, realizing the sliding cooperation of the intermediate plate 42 and the connecting rod 432. The pulley 433 is arranged at equal intervals along the length direction of the connecting rod 432. In the present design, the pulley 433 is arranged at equal intervals along the length direction of the connecting rod 432, and the wheel diameter of the pulley 433 is equivalent to the width of the sliding groove 422, forming a sliding structure with multiple contact points uniformly supported: multiple pulleys 433 can uniformly disperse the weight of the intermediate plate 42, reducing the stress load of a single pulley 433, and avoiding the pulley 433 from being worn or stuck due to overload; at the same time, the pulleys 433 distributed at equal intervals can ensure that the stress is uniform when the plate body 421 slides, so that the plate body 421 smoothly slides in the direction of the sliding groove 422 without jamming.

[0046] In another specific embodiment, the sliding groove 422 and the pulley 433 are reversed, that is, the sliding groove 422 is arranged on the connecting rod 432, and the pulley 433 is arranged on both sides of the plate body 421, in order to improve the universality of the mechanism.

[0047] Specifically, the end of the sliding groove 422 is provided with a guide flared mouth 425, which is gradually enlarged from inside to outside. When the intermediate plate 42 is inserted from the outside of the machine body 1 through the feeding port 2, the guide flared mouth 425 can guide the pulley 433 on the connecting rod 432 to quickly and accurately enter the sliding groove 422, reducing the difficulty of alignment and improving the operation convenience.

[0048] Preferably, the driving member 431 is one of a gas cylinder, a motor-driven screw nut mechanism or a gear and rack mechanism. When a gas cylinder is selected, the cylinder body of the gas cylinder is fixed on the lifting platform 3 of the machine body 1, the piston rod end is connected with the connecting rod 432, and the quick lifting of the connecting rod 432 is realized through the extension and contraction of the gas cylinder; when a motor-driven screw nut mechanism is selected, the motor is fixed on the lifting platform 3, the screw is connected with the output end of the motor, the nut is sleeved on the screw and fixed with the connecting rod 432, the motor drives the screw to rotate, the nut moves along the axial direction of the screw, and then drives the connecting rod 432 to lift; when a gear and rack mechanism is selected, the motor is fixed on the lifting platform 3, the gear is connected with the output end of the motor, the rack is fixed with the connecting rod 432 and engaged with the gear, the motor drives the gear to rotate, the rack moves in the vertical direction, and the lifting of the connecting rod 432 is realized. No matter which driving member 431 is selected, the lifting height of the intermediate plate 42 can be accurately controlled by controlling the action stroke of the driving member 431, meeting the docking requirements of the clamp 6 and the installation station.

[0049] Specifically, in this embodiment, the driving member 431 is a cylinder.

[0050] like Figures 4-10 As shown, the fixture 6 and the installation station are positioned together by magnetic attraction. Specifically, an electromagnet 11 is provided on the fixture installation station, and a material that can be attracted by the electromagnet 11 is provided on the fixture 6. The lifting platform 3 is composed of multiple lifting plates 31 stacked up and down, wherein the bottom lifting plate 31 is provided with an installation station, each installation station is provided with a positioning pin hole 10, and the multiple lifting plates 31 are internally provided with an electromagnet 11 corresponding to each installation station. Correspondingly, each fixture 6 is provided with a positioning pin 7 for inserting and cooperating with the positioning pin hole 10, and the material of the fixture 6 is a material that can be attracted by the electromagnet 11, preferably iron cobalt nickel. In order to improve the positioning accuracy, multiple positioning pin holes 10 and positioning pins 7 can be provided, and the positioning pin holes 10 and positioning pins 7 correspond one to one.

[0051] In the above technical solution, this design realizes the precise positioning of the fixture 6 through the dual positioning mechanism of magnetic attraction and mechanical limit:

[0052] Magnetic positioning provides active guidance: The internal electromagnets 11 located at each installation station within the lifting plate 31 generate a strong magnetic force when energized, creating a uniform and stable attraction force on the fixture 6. When the lifting assembly 43 moves the fixture 6 toward the installation station, the magnetic force actively guides the fixture 6 toward the electromagnets 11, automatically correcting any slight deviations, allowing the fixture 6 to quickly approach the center of the installation station and achieve initial, precise alignment.

[0053] Mechanical positioning achieves precise locking: The bottom lift plate 31 is fitted with a locating pin hole 10 at the installation station, and a corresponding locating pin 7 is located on the fixture 6. Based on magnetic attraction, the locating pin 7 precisely inserts into the locating pin hole 10 under the combined action of magnetism and gravity, forming a rigid mechanical limit. This completely eliminates the horizontal displacement space of the fixture 6, allowing for high-precision cutting of hard materials such as glass sheets 5. This effectively prevents dimensional deviations caused by fixture 6 offset, significantly improving the processing yield rate.

[0054] Preferably, the clamp 6 includes a clamp seat, and the clamp seat is provided with at least two clamping grooves, the clamping grooves are used to install the glass sheet 5, and limiting grooves 9 are provided between adjacent clamping grooves.

[0055] Further preferably, two clamping grooves are formed on the clamp seat, each clamping groove corresponding to one electromagnet 11 to ensure magnetic attraction effect. Each slot hole 423 is provided with a blocking beam 424, the two ends of the blocking beam 424 being fixed on the inner wall of the slot hole 423, and the blocking beam 424 being used in cooperation with the limiting groove 9 to prevent the clamp 6 from falling off. When the clamp 6 is placed in the slot hole 423, the blocking beam 424 is embedded in the limiting groove 9, which can effectively limit the transverse and longitudinal displacement of the clamp 6 on the plate body 421, preventing the clamp 6 from falling off from the middle plate 42 during transfer or lifting, and ensuring the safety of the glass sheet 5 and the clamp 6.

[0056] Further preferably, the positioning pin 7 is arranged at the top of the clamp seat, and the clamp seat is made of a material that can be attracted by the electromagnet 11. To improve the stability of the installation of the clamp 6, specifically, a positioning groove 426 is formed on the side wall of the slot hole 423, and the side of the clamp seat is provided with a positioning column 8 matched with the positioning groove 426. When the clamp 6 is placed in the slot hole 423, the positioning column 8 is just in the positioning groove 426, so as to limit the shaking of the clamp 6.

[0057] As shown in Figures 1-3 The lifting vehicle 41 is arranged outside the diamond wire cutting machine, and is used to carry and transport the middle plate 42, so as to realize the transfer between the middle plate 42 and the diamond wire cutting machine body 1 in the external operation area. The lifting vehicle 41 includes a vehicle body 414, a telescopic rod 411 and a sliding frame 412 installed on the vehicle body 414, and wheels 415 installed at the bottom of the vehicle body 414 to facilitate transportation and transfer of the lifting vehicle 41. The telescopic rod 411 is vertically arranged and fixed at the lower end of the vehicle body 414. The telescopic rod 411 is a hydraulic cylinder and is used to drive the sliding frame 412 to move up and down, so as to adjust the height of the sliding frame 412 through the telescopic rod 411, and facilitate the adaptation to the height of the feeding port 2 of the wire diamond wire cutting machine. The sliding frame 412 is installed on the telescopic rod 411, and a roller set 413 for supporting the middle plate 42 and guiding the middle plate 42 to slide out of or into the diamond wire cutting machine body 1 is installed on the sliding frame 412. The roller set 413 includes two rows of roller units, which are respectively arranged on the two sides of the bottom of the plate body 421. The roller unit is composed of a plurality of independent rollers, and the plurality of independent rollers are arranged at equal intervals along the sliding direction of the middle plate 42. When the middle plate 42 is placed on the sliding frame 412, the roller set 413 can reduce the friction when the middle plate 42 slides, so that the operator can easily push the middle plate 42 to transfer between the sliding frame 412 and the lifting platform 3, and reduce the operation strength.

[0058] The working process is as follows:

[0059] I. Install the glass sheet 5 on the plurality of clamps 6, and then install the plurality of clamps 6 on the middle plate 42;

[0060] II. The intermediate plate 42 is placed on the slide 412 of the lifting vehicle 41 together with the clamp 6, the lifting vehicle 41 is moved to the vicinity of the diamond wire cutting machine, the slide 412 is lifted upward, the slide 412 is aligned with the feeding port 2, and the intermediate plate 42 is aligned with the lifting assembly 43, at this time, the sliding groove 422 is aligned with the roller of the connecting rod 432.

[0061] III. The intermediate plate 42 is driven to slide forward along the slide 412, the sliding groove 422 is moved forward along the roller of the connecting rod 432, after the movement is completed, the lifting assembly 43 starts to work, under the driving of the driving part 431, the connecting rod 432 is lifted upward by a preset distance, so that the distance between the clamp seat and the electromagnet 11 is close enough to enable the electromagnet 11 to firmly adsorb each clamp 6, and the positioning pin 7 is aligned and inserted into the positioning pin hole 10.

[0062] IV. Thereafter, the subsequent cutting work can be started.

[0063] V. After the cutting is completed, the electromagnet 11 is powered off, and the lifting assembly 43 works in reverse: after the electromagnet 11 is powered off, the clamp 6 automatically falls into the groove hole 423, the driving part 431 drives the connecting rod 432 to move downward, so that the connecting rod 432 and the intermediate plate 42 are lowered to the height of the slide 412 of the lifting vehicle 41; thereafter, the intermediate plate 42 is pushed to slide along the pulley 433 and the roller group 413 of the slide 412 to the direction of the lifting vehicle 41, until the intermediate plate 42 is completely transferred to the slide 412.

[0064] In summary, the present application realizes the synchronous bearing and transfer of multiple clamps 6 through the intermediate plate 42, cooperates with the rapid lifting of the lifting assembly 43, does not need to install or disassemble the clamps 6 one by one, significantly improves the overall processing efficiency, and is especially suitable for batch processing scenes. The pre-installation and transfer of the clamps 6 are completed outside the diamond wire cutting machine, the operator does not need to enter the complex machine body 1, avoids the risk of interference with the internal structural parts, effectively prevents the problems of injury of the operator, breakage of the glass sheet 5 and deformation of the clamp 6, and greatly improves the safety. In addition, through the strong adsorption of the electromagnet 11 and the precise cooperation of the positioning pin 7 and the positioning pin hole 10, the present application realizes the double positioning of the clamp 6 on the installation station, ensures the stability of the clamp 6 in the cutting process, effectively avoids the cutting error caused by the deviation of the clamp 6, protects the cutting quality of the glass sheet 5 and other workpieces, and meets the high-precision processing demand. The lifting vehicle 41 serves as an external special transport carrier of the intermediate plate 42 and the clamp 6, undertakes the key transfer function, reduces the operation strength, and improves the convenience.

[0065] The number and position of the slot holes 423 of the intermediate plate 42 can be adjusted according to the specifications of the diamond wire cutting machine mounting station, the type of the driving member 431 can be flexibly selected, and the height of the slide 412 of the lifting vehicle 41 can be adjusted, so that the feeding and discharging mechanism is suitable for different models and different specifications of diamond wire cutting machines, and can be adapted to cutting and processing of various hard materials such as glass, ceramic, monocrystalline silicon, has a wide range of applications, and has strong popularization value.
