Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic processing equipment, and particularly relates to a high-efficiency sheet separation precision engraving machine. BACKGROUND

[0002] When the sheet materials such as mobile phone cover plates and tempered films are automatically processed, automatic feeding and discharging are needed, and the biggest difficulty in the automatic feeding and discharging process is how to put the sheet materials into the processing equipment one by one for processing. Glass and other raw material sheet materials are stored in a stacked manner, and the sheet materials are closely placed and easy to stick. The processing technology of sheet materials such as glass tempered films and cover plates involves cutting, cutting, polishing, cleaning, tempering, etc. In most processing technologies, the glass sheet will contact various cooling liquids, polishing liquids and cleaning liquids, resulting in sticking between the glass sheet materials. The sheet material from the stacked and closely placed state to the separated state is related to the entire processing process. When the mechanical arm is used for automatic processing, the sheet materials need to be separated, and then the mechanical arm is supplied with the sheet materials.

[0003] In the traditional separation scheme, such as the stacking glass sheet separation positioning device mentioned in the patent No. 201821336633.X made by the applicant before, the air floatation separation method is used, compressed air is used to blow the side wall of the stacked glass sheet, so that the glass is separated and floated, and then the mechanical arm or the material taking mechanism takes the sheet one by one, and supplies the equipment for processing. This scheme is suitable for dry glass sheet materials. When the glass sheet material is wet or soaked, the two sheet materials are adhered and closely placed, and pure reliance on compressed air cannot ensure the success rate of separation. Once it cannot be ensured that only single sheet is separated and taken out each time, it will lead to the failure of processing, the glass sheet material is broken, and if the processing cannot be found in time, it will lead to a large amount of raw material waste, and also affect the service life of the machine.

[0004] Subsequently, in view of the problems existing in the taking and placing of the wet and sticky sheet material, the applicant has made further research and development, and has made a patent application No. 202021348997.7. The technical solution adopts a water tank filled with liquid to immerse the glass in the liquid, and the immersion of the liquid in the water tank makes the liquid adsorption between the sheet materials disappear and the liquid pressure between the sheet materials in the immersed state relatively balanced, so that the adhesion between the sheet materials is further eliminated. Then, the glass sheet material is separated in a completely separated state by using a liquid jet from the four sides of the stacked glass sheet material, and then the mechanical hand is relatively easy and smooth to take out the single sheet. This kind of immersion type separation scheme can better solve the scratch of the sheet material, and better separate the glass sheet material after soaking in water. However, it is found in practice that broken glass is inevitable during the taking and placing of the glass sheet material, especially when processing large sheet materials, which is more likely to produce broken glass. Due to various water spraying devices installed in the water tank, raw material tank and other reasons, the structure is relatively complex, and the broken glass will accumulate in the water tank and is not easy to clean. If the water tank is not cleaned in time, the accumulated broken glass at the bottom of the water tank will hurt people and raw materials. The limited space on the machine tool bed itself makes the cleaning difficulty further increased. SUMMARY

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Embodiment:

[0043] The embodiment of the present application provides a precision carving machine with high-efficiency sheet material separation, which combines the advantages of the prior art and has the advantages of Figs. 1 to 4As shown, it comprises a machine body 100, a mechanical hand 200, a machining spindle 300, a machining table 400 on the machine body, a discharging device (omitted in the figure) and a liquid spraying sheet material separating device. The mechanical hand is used to take out the sheet material to be separated from the liquid spraying sheet material separating device and place it on the worktable, and take off the processed sheet material from the worktable and place it on the discharging device. The machining spindle is used to process the sheet material on the worktable. The machine body 100 is provided with a gantry 101, and the machining spindle is installed on the gantry. The gantry 101 is also provided with a mechanical hand support 102 at the front side, and the mechanical hand 200 is installed on the mechanical hand support 102 and can move in XYZ directions. The machine body 100 has two worktables 400 that can move along the Y axis. The automatic feeding and discharging of the mechanical hand can realize non-stop processing. The front part of the machine body is arranged with the liquid spraying sheet material separating device and the discharging device along the X direction.

[0044] The liquid spraying sheet material separating device in the present example comprises a material rack 10 and a liquid spraying mechanism 20. The material rack 10 comprises three material frame units 11, which are used to arrange and place the sheet material 90 to be separated, i.e. a whole stack of closely arranged sheet materials (sheet material to be separated) is placed in the material frame unit before processing.

[0045] The material frame unit 11 comprises front and rear side plates (front side plate 111, rear side plate 112) and connecting rods 113 connected to the left and right sides of the front and rear side plates. Two support rods spaced apart in the left and right directions are connected to the bottom of the front and rear side plates, so that the two sides and the bottom side of the material frame unit are partially hollowed out. In this way, when the sheet material breaks, the fragments will fall outside the material frame unit from the hollow part, and will not accumulate in the material frame unit, which is convenient for cleaning. The two support rods form two-point support for the bottom of the sheet material, which makes the sheet material support more stable and also allows the broken pieces to fall outside the material frame unit from the hollow part between the two support rods. Since the material rack is suspended on the machine body, the fragments will directly fall on the machine body and then be washed away by the processing liquid, so that the machine body can remain clean. One of the two connecting rods of the material frame unit 11 is adjustable in the left and right directions of the front and rear side plates. As an example, the connecting rod on the right side is adjustable. A long hole 114 is provided at the corresponding position of the front and rear side plates, and the connecting rod can be locked at a certain position of the long hole of the front and rear side plates by a bolt assembly, so as to adjust the spacing width between the two connecting rods to store sheet materials of different sizes, thereby improving the applicability of the material frame unit. In order to prevent the sheet material from being scratched during feeding and discharging, a sheet material pad is arranged on the inner side of the front and rear side plates in the material frame unit. The sheet material pad can be made of flexible plate material.

[0046] In other embodiments, the front and rear side plates of the material frame unit can be connected with a support plate to form a hollow on both sides and the bottom of the material frame unit. The support plate has a certain width to ensure stable support of the sheet material.

[0047] The liquid spraying mechanism 20 includes a liquid spraying unit 21 corresponding to the material frame unit 11. The liquid spraying unit 21 has a separation nozzle 211 arranged towards the inside of the material frame unit, so that the separation nozzle 211 can be aligned with the side wall 901 of the arranged sheet material and can spray liquid to the gap between the first arranged sheet material and the adjacent sheet material (second sheet material). Since the soaking of the water tank is eliminated, the sheet material to be separated is in an air environment, and the separation nozzle needs to continuously spray liquid towards the sheet material to be separated. Under the action of hydraulic pressure, the liquid gradually penetrates inward from the gap between the two sheet materials. If the hydraulic pressure continues to act, the liquid continues to penetrate inward until the liquid penetrates through the gap, similar to the liquid forming a channel in the gap. The liquid penetrates from one side to the other side in the gap, or penetrates from both sides to the center until it converges. When the liquid advances in the direction of the hydraulic pressure, it also penetrates to the periphery. Therefore, even if some parts of the gap between the two sheet materials are not fully penetrated by the liquid, the liquid penetration in one part will cause the tension in the gap to separate the other parts. The inventor's discovery also makes it possible to use liquid for separation without immersing the sheet material in the water tank, thereby realizing the transition from immersion separation to liquid spraying separation.

[0048] In the present embodiment, the liquid spraying unit 21 has a group of separation nozzles 211 arranged on the left and right sides of the arranged sheet material in the material frame unit 11, that is, liquid is sprayed from the left and right sides of the sheet material to the center, allowing the liquid to gradually converge from both sides to the center in the gap between the two sheet materials under the action of continuous hydraulic pressure, and finally separating the two sheet materials. Therefore, the group of separation nozzles includes one separation nozzle arranged on each of the left and right sides. If two separation nozzles are arranged on each of the left and right sides, they are also considered as a group of separation nozzles. When the separation nozzles are arranged in pairs on the left and right sides of the sheet material, the best position in the vertical direction is arranged at the position of the upper half of the sheet material, that is, the sheet material is divided into an upper half and a lower half, and the separation nozzles are best arranged on the upper half. The middle line of the upper half is the best position, which allows the liquid to converge to the center while penetrating to the top side of the gap between the sheet materials in the vertical direction, achieving faster separation.

[0049] The diameter of the separation nozzle in the embodiment can cover at least 3 thicknesses of the sheet material along the arrangement direction of the sheet material, so that the liquid sprayed by the separation nozzle can impact not only the gap between the first sheet material and the adjacent sheet material, but also the gap between the second sheet material and the third sheet material. When the first sheet material is separated, the second sheet material and the third sheet material are also separated, so that the separation efficiency can meet the continuity of the automatic mechanical hand taking material. In addition, the separation nozzle is inclined relative to the first arranged sheet material in the material frame unit to spray liquid from the rear side of the sheet material. That is, the liquid spray extension line of the separation nozzle is not parallel or coincident with the plane of the first sheet material, but the liquid spray extension line of the separation nozzle passes through the plane of the first sheet material from the rear side of the first sheet material to the front side. Of course, the inclination angle of the separation nozzle cannot be too large, otherwise the liquid will escape from the side and rarely enter the gap between the two sheet materials. Generally, the inclination angle is 1° to 5°. In this way, it can be ensured that the liquid will effectively enter the gap between the two sheet materials, and the forward component force generated by the liquid can also promote faster separation of the sheet materials.

[0050] In other embodiments, the liquid spraying unit has a group of separation nozzles arranged relative to the top side of the arranged sheet material in the material frame unit, that is, the separation nozzle is arranged in the upper position to spray liquid from the top side to the bottom side of the sheet material. Under the action of continuous liquid pressure, the liquid gradually converges from the top side to the bottom side in the gap between the two sheet materials. When the vertical edge length of the sheet material is greater than the horizontal edge length, the liquid has penetrated the gap in the left-right direction before reaching the bottom side of the sheet material, and the separation of the two sheet materials is finally achieved. When a group of separation nozzles are arranged relative to the top side of the arranged sheet material, it is obvious that the group of separation nozzles can have only one separation nozzle, that is, one separation nozzle in the upper position. Of course, the liquid spraying unit can have two, three or more separation nozzles arranged in the upper position along the left-right direction of the sheet material to allow the liquid to penetrate in a larger range.

[0051] It can be seen that the liquid spraying unit and the material frame unit form a one-to-one correspondence relationship, that is, the material rack includes a plurality of material frame units, and the liquid spraying mechanism includes a plurality of liquid spraying units corresponding thereto. In other embodiments, the material rack includes two or more material frame units arranged along the left-right direction of the sheet material, and the liquid spraying mechanism also includes two or more liquid spraying units corresponding to the material frame units. If there is only one material frame unit, the liquid spraying unit can also be provided with one.

[0052] The two pieces of material are separated under the impact of the separation nozzle of the liquid spraying unit, and once the first piece of material is separated, it will have a certain amplitude of movement or swing, but the amplitude of the movement or swing is generally difficult to control, and the robot automatic suction is prone to deviation, resulting in suction failure, so the first piece of material needs to be positioned. If a hard material such as a stopper or a positioning member is used to position the first piece of material after separation, the position of the stopper will be fixed, and as the material frame unit is gradually taken away, the hydraulic pressure remains constant, and the distance of the material impacted apart is different. The first piece of material cannot be positioned by the stopper, and the robot suction will still fail. The present embodiment improves the soft positioning, i.e., the liquid spraying unit 21 has a positioning nozzle 212 arranged towards the front of the material for spraying liquid to the front of the first piece of material in the material frame unit to maintain the stability of the first piece of material. The liquid sprayed by the positioning nozzle enables the first piece of material to always receive a force applied to the rear side of the material arrangement direction. The liquid sprayed by the separation nozzle enables the first piece of material to receive a forward liquid tension, and the liquid sprayed by the positioning nozzle enables the first piece of material to receive a rear water pressure, thereby maintaining the stability of the first piece of material in the front-rear direction, and then being stably sucked by the automatic robot. The reasonable cooperation of the separation nozzle and the positioning nozzle greatly improves the success rate of material separation, and the material is more easily sucked.

[0053] The liquid spraying unit in the present embodiment has a set of positioning nozzles, which includes two positioning nozzles arranged at positions close to the left and right sides relative to the front of the material. The two positioning nozzles are located at positions relative to the upper body of the material, and the separation nozzle is arranged close to the positioning nozzle in the up-down direction. Thus, corresponding to the separation nozzle, the positioning nozzle can better cooperate with the separation nozzle to achieve material separation. The liquid spraying unit can also be provided with another set of positioning nozzles, which includes at least one positioning nozzle arranged at a position close to the bottom side relative to the front of the material. In the present embodiment, two positioning nozzles are arranged at positions close to the bottom side, which has better stability. In other embodiments, one or three positioning nozzles in the other set of positioning nozzles are also acceptable.

[0054] In other embodiments, the liquid spraying unit can only have one positioning nozzle arranged at a position close to the central region relative to the front of the material. The above statements are all about arranging the positioning nozzle at a position corresponding to the edge side of the material. Here, only one positioning nozzle is arranged at a position corresponding to the central region of the front of the material, which is equivalent to applying a support point to the central region of the material. It can be understood that the central region is a certain area spreading from the center point of the material, so that the hydraulic force of the liquid sprayed by the positioning nozzle is not limited to a center point, but a region can be used as a force point of the liquid sprayed by the positioning nozzle.

[0055] It can be understood that the first piece of material in the material frame unit changes as the piece of material is taken out piece by piece. After the first piece of material is taken out, the second piece of material originally becomes the first piece of material (the first piece of material). In order to ensure that the separation nozzle of the liquid injection unit can always inject liquid into the gap between the first piece of material and its adjacent piece of material in the material frame unit, the separation nozzle needs to move relatively with the material frame unit. Therefore, the piece separation device in the embodiment further includes a driving mechanism for driving the liquid injection unit or for driving the material frame unit to relatively move along the piece arrangement direction between the liquid injection unit and the material frame unit. The driving mechanism has a driving motor assembly, a track laid along the piece arrangement direction, and a slider driven by the driving motor assembly to move on the track, and the liquid injection mechanism or the material rack is integrally linked with the slider. The driving mechanism is installed on the bed and shares the Y-axis track platform 109 with the Y-axis drive of one of the worktables, and the spatial arrangement is more reasonable. The Y-axis drive refers to the related driving components that realize the movement of the worktable in the Y-axis direction, and the track platform is a base structure on which the track is laid.

[0056] The liquid injection mechanism can be implemented by many types of structures. In the embodiment, a relatively simple structure is adopted. The liquid injection mechanism in the embodiment includes a support frame, which includes vertical rods 22 located on both sides of the material rack and a first cross rod 23 spanning between the two vertical rods 22. The vertical rod 22 is a telescopic adjusting rod. In the embodiment, the vertical rod is divided into two ends and is adjusted and locked by a long hole and a screw assembly, so as to be suitable for different sizes of pieces of material and to adjust the height of the first cross rod, thereby adjusting the positions of the separation nozzle and the positioning nozzle, and the use is more flexible. The separation nozzle 211 is installed on the first cross rod 23 through a mounting block 24. The mounting block 24 has a liquid supply connector 25 for connecting an external liquid supply unit, and the separation nozzle 211 communicates with the liquid supply connector 25. The design of the first cross rod spanning makes it possible for each material frame unit to have a separation nozzle corresponding thereto through the transverse installation of the first cross rod in multi-station separation.

[0057] A pair of mounting blocks 24 extending downward are mounted on the first horizontal rod 23 at positions corresponding to the left and right sides of each frame unit. In a pair of mounting blocks corresponding to the same frame unit, one mounting block is fixed at the top end of the first horizontal rod, and the other mounting block is mounted on the first horizontal rod in a manner that its position can be adjusted in the axial direction of the first horizontal rod. The mounting position of the first horizontal rod 23 corresponding to the other mounting block is a long hole 231 formed in the axial direction of the first horizontal rod. The mounting block 24 is mounted on the first horizontal rod 23 at a position corresponding to the long hole 231 by a bolt assembly. For example, the top end of the mounting block has a threaded hole, and a screw can pass through the long hole to lock the top end of the mounting block at a certain position of the long hole of the first horizontal rod. When the position needs to be adjusted, the bolt is loosened, the mounting block is moved left and right in the long hole, and then the bolt is tightened. Alternatively, an upward extending screw is fixed at the top end of the mounting block, the screw passes through the long hole 231, and then a nut is used to lock it. This combination of long hole and screw assembly has the simplest structure and the lowest cost, and can achieve the effect of adjusting the position. Once the position is adjusted, the mounting block is also fixed in position.

[0058] A pair of mounting blocks 24 extending downward are mounted on the first horizontal rod 23 at positions corresponding to the left and right sides of each frame unit. In a pair of mounting blocks corresponding to the same frame unit, one mounting block is fixed at the top end of the first horizontal rod, and the other mounting block is mounted on the first horizontal rod in a manner that its position can be adjusted in the axial direction of the first horizontal rod. The mounting position of the first horizontal rod 23 corresponding to the other mounting block is a long hole 231 formed in the axial direction of the first horizontal rod. The mounting block 24 is mounted on the first horizontal rod 23 at a position corresponding to the long hole 231 by a bolt assembly. For example, the top end of the mounting block has a threaded hole, and a screw can pass through the long hole to lock the top end of the mounting block at a certain position of the long hole of the first horizontal rod. When the position needs to be adjusted, the bolt is loosened, the mounting block is moved left and right in the long hole, and then the bolt is tightened. Alternatively, an upward extending screw is fixed at the top end of the mounting block, the screw passes through the long hole 231, and then a nut is used to lock it. This combination of long hole and screw assembly has the simplest structure and the lowest cost, and can achieve the effect of adjusting the position. Once the position is adjusted, the mounting block is also fixed in position.

[0059] In other embodiments, the separation nozzle can be a separate nozzle structure that is then mounted to the mounting block. In this embodiment, in order to further simplify the structure and reduce space occupation, two interconnected pipe openings are provided on the mounting block body, one of which is used as a separation nozzle, and the other is used to install a liquid supply connector. That is, the separation nozzle and the pipeline are integrated on the mounting block, without the need for additional materials and additional space occupation, reducing the possibility of scratching the sheet material.

[0060] In this embodiment, the mounting block is a strip-shaped body, which has a relatively regular structure and is convenient to combine or mount with other objects. The extension block is mounted on the lower end of the mounting block in a detachable manner. The lower end of the mounting block is provided with an inner recessed step surface, and the extension block is mounted on the inner recessed step surface to form a match. This can further reduce space occupation and make the mounting of the extension block and the mounting block more stable. In other embodiments, the mounting block can also be a rod-shaped body, which is also simple and convenient to assemble and mount.

[0061] The front and back width of the lower end of the mounting block 24 is larger than the front and back width of the block body, forming a mounting portion of the mounting block, so that the mounting block is similar to an L-shaped mounting structure, and the separation nozzle is formed on the inner side of the mounting portion, so that the separation nozzle has more space on the mounting portion when a larger caliber is required, and the mounting of the mounting block and the liquid supply connector is also facilitated, and the mounting of the extension block is also facilitated.

[0062] In order to further ensure that the positioning effect of the first sheet material is more stable, a second cross rod 27 is arranged on the vertical rod 22, and a positioning nozzle for setting towards the front surface of the sheet material and spraying liquid to the front surface of the first arranged sheet material in the sheet material rack to maintain the stability of the first arranged sheet material is arranged at the front end position corresponding to each material frame unit on the second cross rod 27. The position of the second cross rod in the up and down direction on the vertical rod corresponds to the lower part of the sheet material. In other embodiments, the position of the second cross rod in the up and down direction on the vertical rod corresponds to the middle part of the sheet material; or the second cross rod is adjustably mounted on the vertical rod in the up and down direction. The adjustable mounting method of the second cross rod can refer to the structure of the adjustable mounting position of the mounting block. According to the different sizes of the sheet material, the position of the second cross rod can be selected, and the universality is stronger.

[0063] The extension block is detachably mounted on the second cross rod, and the extension block 26 is provided with two mutually communicating pipe openings, one of which is used as a positioning nozzle, and the other of which is used for mounting a liquid supply connector 25. The nozzle and the interface are integrated through the block structure, which simplifies the structure, reduces the cost, and reduces the space occupation, and the structure is more stable.

[0064] In other embodiments, the second cross rod is internally hollow to form a liquid supply pipeline, and the side wall on the side of the second cross rod facing the sheet material is provided with a port hole communicating with the liquid supply pipeline for the positioning nozzle. Such a second cross rod has no other excess space and lower cost, and the structure is simplified to the extreme.

[0065] The two vertical rods 22 of the liquid spraying mechanism support frame are mounted on a moving base 28, and the driving mechanism drives the moving base 28 to move in the sheet material arrangement direction. The moving base is actually moved together with the slider of the driving mechanism. The moving base can move the liquid spraying mechanism on it more stably. In other embodiments, the sheet material rack can be mounted on the moving base, and the liquid spraying mechanism remains stationary, which can also achieve the effect of moving the separation nozzle relative to the material frame unit.

[0066] In other embodiments, the separation nozzle is mounted on the vertical rod through the mounting block. For example, when there is only one material frame unit or only two material frame units, the separation nozzles on the two vertical rods spray liquid in the central direction. Although the structure is easier to realize, it cannot be expanded to more material frame units like the first cross rod.

[0067] Therefore, in other embodiments, the support frame can also include vertical rods on both sides of the material frame unit, liquid pipes for connecting external liquid supply units are arranged in the vertical rods on both sides, and water outlets are arranged on the opposite inner sides of the vertical rods as separation nozzles. That is, vertical rods are arranged on both sides of each material frame unit, so that the material frame unit can expand more separation nozzles in the up-down direction on both sides, and the horizontal rods can be omitted. Further, the vertical rods have protruding blocks extending to the front side of the sheet material arrangement direction and bent to the inside of the material rack, and the protruding blocks have positioning nozzles arranged towards the front side of the sheet material for front-side liquid injection to the sheet material arranged in the material rack to maintain the stability of the first sheet arrangement. That is, the vertical rods themselves can also expand the structure of the positioning nozzles.

[0068] During processing, the separation nozzles spray the sheet material in the material frame unit for a certain period of time, for example, at least 30 seconds, after the first sheet material and the connected sheet material are separated by liquid impact, the manipulator takes out the sheet material from the material frame unit and places it on the workbench, and the processing spindle processes it. After processing, the processing spindle avoids, the manipulator takes and places the processed sheet material to the discharging device, and then continues to take the material from the liquid injection type sheet material separation device, and so on, until the sheet material in the material frame unit is processed.

[0069] The above describes in detail a liquid injection type sheet material separation device provided by an embodiment of the present application, and the principles and implementation manners of the present application are described by applying specific examples. The above embodiment description is only used to help understand the core idea of the present application; at the same time, for those skilled in the art, according to the idea and method of the present application, the specific implementation manner and application range will be changed, and the above description should not be understood as a limitation of the present application.
