Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fine carving machine technology, and specifically relates to a side-turning feeding and discharging fine carving machine. BACKGROUND

[0002] The technical solution of the prior application 2023102930818 of the applicant proposes a fine carving machine with high-efficiency sheet material separation, in which the raw material (sheet material to be processed) bin uses a liquid spraying method to separate the glass sheet material, and the finished product is inserted into a customized rack. This method arranges the raw material bins at equal intervals according to the spindle pitch, and the multiple suction cups of the material taking mechanical arm are installed on a single shaft at equal intervals with the spindle pitch of the machine tool. Only a 90-degree rotation along the horizontal center axis is required to place the vertically arranged sheet material in the raw material bin on the processing table in a horizontal position. The mechanical structure is relatively simple, and therefore, it is widely used in the industry. However, the problem that is easily overlooked is that the storage of the raw material and the finished product is in the vertical direction (vertical direction) in the raw material frame and the finished product frame. This storage method has a large vertical relative displacement when the raw material is separated and extracted, and the sheet materials are more likely to scratch each other. When the finished product is stored, the long side of the sheet material is vertically placed, which is easy to stick and bend. The subsequent ultrasonic cleaning or tempering process will have a higher rejection rate, and the larger the processing size, the higher the rejection rate, which does not meet the yield requirements of the subsequent process.

[0003] If the long side of the sheet material is placed transversely, the storage space of the loading area on the machine table will be greatly affected. For example, the transverse space of a machine table of a multi-spindle precision carving machine is about 1 meter wide, the left side is a loading area, about 0.5 meters, the short side of the sheet material is 0.1 meters, and the long side is 0.2 meters. According to the above-mentioned manner of placing the short side of the sheet material transversely, the sheet material in the loading area can be placed in 4 columns, but if the long side of the sheet material is placed transversely, only 2 columns can be placed. Moreover, widening the raw material rack and the finished product rack of the original scheme on the basis of the existing scheme requires matching the main shaft spacing of the multi-spindle precision carving machine to be greater than the length of the sheet material. After the addition of multiple spindles and double stations, the width and stroke of the machine tool will be multiplied, which will also cause the manufacturing cost of the equipment to increase substantially. It does not meet the market demand. Content of the utility model

[0035] 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, rather than 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.

[0036] Embodiment:

[0037] The embodiment of the present application provides a side-turning up and down material fine carving machine, which is combined with Figures 1 to 7As shown, including machine 1, machine is the main working area of the machine tool, is the carrier of each part. The machine 1 is provided with a workbench 2, a material taking and placing manipulator 3, a feeding area and two or more machining spindles 4. The machining spindle is also called the machining head. In this embodiment, a double Y-axis workbench is adopted, that is, the two Y-axis moving workbenches correspond to the machining spindles to form alternate non-stop machining, which improves the machining efficiency. In order to facilitate the reader to understand, in this embodiment, the three machining spindles are arranged in the front-to-back direction of the workbench, and the three machining spindles are arranged in the left-to-right direction of the workbench. The three machining spindles are arranged in the front-to-back direction of the workbench, and the three machining spindles are arranged in the left-to-right direction of the workbench. Figure 1 As a reference, define the three-dimensional coordinate system and direction, where the lateral direction is the left-right direction of the machine also called X-axis direction or X direction, the longitudinal direction is the front-back direction of the machine also called Y-axis direction or Y direction, and the vertical direction is the up-down direction of the machine also called Z-axis direction or Z direction. The workbench 2 has three machining positions 21 matched with the three machining spindles, the feeding area is located in front of the longitudinal direction of the workbench 2, and the feeding area is provided with three feeding frames 5 corresponding to the machining positions 21 for arranging and placing the short edge 91 of the sheet material 9 vertically and the long edge 92 longitudinally. The material taking and placing manipulator 3 is provided with three taking and placing parts 31 corresponding to the machining positions. This embodiment is a three-spindle machining tool with three machining positions on the workbench, three taking and placing parts on the manipulator and three feeding frames. Other embodiments can be double-spindle machining tools or four-spindle machining tools or more spindle machining tools. This embodiment takes the three-spindle machining tool as an example for introduction, which is also applicable to other number of spindle machining tools. The taking and placing part can carry the sheet material to flip and change between the vertical direction and the lateral direction along the longitudinal axis. The vertical direction here includes a slight inclination away from the vertical direction. If the sheet material is placed in the feeding frame with a certain inclination angle, the taking and placing part will flip and change between the inclination angle and the lateral direction. The material taking and placing manipulator 3 carries the taking and placing part 31 to move between the feeding area and the machining position for taking out the vertical sheet material in the feeding frame and placing it flat on the machining position so that the sheet material is placed on the workbench with the short edge horizontally and the long edge vertically. It can be seen that in this embodiment, the sheet material is placed vertically in the feeding area with the long edge longitudinally and the short edge vertically, and the taking material manipulator is matched with the side turning taking material, which can realize normal machining. Compared with the prior art, the sheet material is placed flat in the feeding area with the long edge longitudinally and the short edge horizontally, or the sheet material is placed vertically with the long edge vertically and the short edge horizontally, without increasing the width of the machine, more sheet materials can be accommodated, the space structure layout on the machine is more reasonable, and the vertical height of the sheet material is reduced by placing the short edge vertically, avoiding slight deformation of the sheet material under the action of gravity, reducing the vertical stroke of the sheet material taking and placing process, reducing the probability of mutual scratching of the sheet material during the taking and placing process, reducing the separation and extraction time of the sheet material during vertical extraction, and improving the efficiency and quality of the taking and placing process.

[0038] The transversely extending accommodation space of the feeding frame 5 in the embodiment can make the sheet material stand in the accommodation space of the feeding frame and arrange in the transverse direction, and the feeding area is a transverse arrangement area. The three feeding frames 5 are distributed in the transverse direction on a feeding frame 51, and the spacing between adjacent feeding frames corresponds to the spacing between adjacent taking and placing parts. In the prior art, the sheet material is generally laid flat or arranged in the longitudinal direction. The three feeding frames in the embodiment are distributed in the transverse direction on the machine table feeding area, and the sheet material is also arranged in the transverse direction, so as to cooperate with the taking and placing part to take the material by side turning, thereby efficiently solving the problem of taking and placing the sheet material by side standing.

[0039] In order to further optimize the processing procedure, the sheet material in the feeding area is separated by the mechanical hand one by one, and then processed by the processing spindle on the processing position on the workbench. The processed sheet material is placed in the discharging area after processing. Therefore, the machine table is provided with a discharging area in the embodiment, and the discharging area is located in front of the workbench 2 in the longitudinal direction. The discharging area is also provided with three discharging frames 6 corresponding to the processing position 21. The discharging frame 6 has a transversely extending accommodation space. The discharging frame 6 has equidistantly distributed grooves in the transverse direction for arranging the sheet material in the vertical direction and the longitudinal direction, so that the sheet material stands in the accommodation space of the discharging frame and arranges in the transverse direction. The three feeding frames are distributed in the transverse direction on a discharging frame 61, and the spacing between adjacent discharging frames 6 corresponds to the spacing between adjacent taking and placing parts. The sheet material can be arranged in the discharging groove of the discharging area after being taken and processed, and will not be scratched by each other, which is convenient for subsequent processing and production. The layout of the discharging frame corresponding to the feeding frame is consistent, which can better cooperate with the efficient taking and placing action of the taking and placing part under the condition of not increasing the width of the machine tool. The spacing between adjacent parts in the embodiment refers to the distance between the centers of the parts, not the distance between the boundaries of the two parts.

[0040] The structure and working mode of the material taking and placing manipulator are optimized in the embodiment. The material taking and placing manipulator comprises a moving base 32, three pickup blocks 33 rotatably mounted on the moving base 32 around a longitudinal axis, and a pickup driving mechanism for driving the pickup blocks to rotate. The spacing between adjacent pickup blocks 33 is the same, and the pickup blocks 33 are provided with suction cup assemblies 34 to form taking and placing parts. The moving base is a carrier of the pickup blocks. The moving base is built according to actual conditions. In the embodiment, support frames are arranged on both sides of the machine table, longitudinal rails are arranged on the support frames, longitudinal sliding seats are arranged on the longitudinal rails, transverse rails are arranged on the longitudinal sliding seats, vertical sliding seats are arranged on the transverse rails, and the vertical sliding seats are provided with carrying parts for mounting the taking and placing parts to form the moving base. The moving base can move the taking and placing parts between the feeding area, the processing position, and the discharging area to realize taking, placing, and transferring of the sheet material. In other embodiments, other driving modes in the prior art can be used to drive the movement of the moving base, which will not be described here. In the embodiment, the pickup blocks rotate around a longitudinal axis. The longitudinal axis can be virtual or physical. From the perspective of a worker standing in front of the machine table, the taking and placing working surface of the pickup block presents a side-flipping action, and the rotation axis is longitudinal. This structure can make the pickup block flip by 90 degrees when the sheet material is taken out of the feeding frame, so that the short side is changed from vertical to horizontal and then placed horizontally on the processing position. The structure is optimized and practical, and when cooperating with the feeding frame, the action of the manipulator is simpler and more efficient.

[0041] In order to make the synchronization of the taking and placing parts better, in the embodiment, each pickup block is connected with a linkage rod 38 through a crank 39, that is, a crank is arranged on each pickup block. Here, the crank refers to a swing arm arranged to make the pickup block rotate around the rotation center. The pickup block can be rotated through the swing of the crank. The pickup driving mechanism drives one of the pickup blocks to rotate, thereby driving the other pickup blocks to rotate synchronously through the linkage rod. For example, in the embodiment, the crank is arranged on the middle pickup block of the three pickup blocks. When the middle pickup block is driven to rotate, the linkage rod drives the other two pickup blocks to rotate synchronously. This can ensure that one driving mechanism uniformly and synchronously drives the three pickup blocks, and the side-flipping is smoother and more stable. In another embodiment, one of the cranks is used as a driving point of the pickup driving mechanism, which is equivalent to using the crank as a swing arm. The crank has a dual function, and the structure is simplified. In other embodiments, the pickup driving mechanism can directly drive the linkage rod to swing, thereby driving all the pickup blocks to rotate synchronously. This can reduce the arrangement of components on the pickup blocks, avoid interference with the taking and placing of the sheet material due to the increase of components on the pickup blocks, and optimize the application of driving force of the whole structure, so that the spatial layout is more reasonable, and the cooperation space between structures is smoother.

[0042] Take one of the pickup block (such as the middle pickup block) along its rotation radial extension of a swing arm 30 as an example, the pickup drive mechanism includes driver 35, vertically movable vertical slider 36 and with vertical slider rotation connection connecting rod 37, the other end of the connecting rod 37 is rotatably connected to the swing arm 30, the driver 35 drives the vertical slider 36 sliding, vertical slider 36 through the connecting rod 37 swing pickup block synchronous rotation. The driver can be a motor, cylinder or oil cylinder and other commonly used drive, motor can be matched with screw assembly, cylinder or oil cylinder can be matched with slide rail slider assembly, even with the piston rod end as a slider, the embodiment of the motor is matched with screw assembly, nut seat as a slider is driven by the motor screw and slides. The slider and the connecting rod of the embodiment are rotatably connected to the swing arm, which is more conducive to the realization of synchronous rotation of the pickup block, and the structure is more reasonable and practical. It can better control the cost and is easy to produce.

[0043] If the direct drive connecting rod is used, the connecting rod has a swing connection point, and the other end of the connecting rod is rotatably connected to the swing connection point. The connecting rod drives the connecting rod to swing to make the pickup block synchronous rotation. This way reduces the use of parts, optimizes the structure, and the connection point is located on the connecting rod, which does not affect the sheet material taking and placing for various angle turning of the pickup block. Moreover, the stress point is closer to the driver, the stress is more balanced, and the driving performance is more stable.

[0044] The structure of the moving seat is also optimized in the embodiment. The moving seat 32 has a vertical plate 321, and a horizontal rod 322 is fixed to the lower side of the vertical plate to form an inverted T-shaped moving seat. Simplifying the moving seat is conducive to flexible movement of the moving seat. The shape is also conducive to the horizontal arrangement and installation of the pickup block. The horizontal rod 322 has two or more than two support shafts 311 extending in the longitudinal direction. The distance between adjacent support shafts 311 corresponds to the distance between processing positions. Adjacent two support shafts are open on the side away from the horizontal rod. The moving seat and the support shafts in the embodiment form a shape similar to a rake, which is conducive to the flexible extension of the taking and placing part into the feeding frame or the discharging frame from the longitudinal or vertical direction. The structure design is more reasonable, simple and practical, and convenient for installation and debugging of the pickup block.

[0045] The vertical plate 321 of the moving seat 32 is provided with a vertical opening 320 in this embodiment. The driver is arranged on the side of the vertical plate away from the taking and placing part. The vertical slider 36 extends from the side of the vertical plate away from the taking and placing part to the side of the vertical plate close to the taking and placing part through the vertical opening 320. The vertical opening provides a through space for the vertical slider and also plays a guiding role on the vertical slider, thereby ensuring the smooth sliding of the vertical slider and reducing the shaking. The connecting rod 37 is rotatably connected to the end of the vertical slider close to the taking and placing part. In this way, the driver is arranged on one side of the vertical plate, and the connecting rod and the taking and placing part are arranged on the other side of the vertical plate. The overall balance of the components on the moving seat is maintained, the gravity on both sides of the vertical plate is relatively balanced, and the stability of the moving seat during movement is improved.

[0046] In order to make the support shaft extending longitudinally on the moving seat more stable during the rotation of the pickup block, a sleeve is introduced in this embodiment. That is, the sleeve 313 is sleeved on each support shaft 311 through the bearing 312. Each pickup block 33 is installed on the sleeve 313. The crank 39 is arranged on the sleeve 313 to drive the sleeve to rotate relative to the support shaft. The cooperation between the sleeve and the bearing can prevent the pickup block from tilting during rotation. The two ends of the sleeve 313 are sleeved on the support shaft 311 through the bearing 312, which can maintain a more balanced stress. The space between the two bearings is left empty, and no other components are filled in the middle of the support shaft, thereby saving costs. The two ends of the sleeve are closed, and a cover 316 can be arranged on the end of the sleeve that is open to the outside. The other end is closed by the bearing or the installed carrier. This structure can not only protect the components in the sleeve, but also better prevent the sleeve from tilting. Further, an open clamping ring 314 is arranged on the outside of the sleeve 313. The openings of the open clamping ring 314 extend out corresponding clamping blocks 315 along the radial direction of the sleeve as cranks. The corresponding clamping blocks 315 are provided with locking mechanisms for clamping the corresponding clamping blocks to tightly hold the sleeve. The locking mechanism can be a bolt and a threaded hole on the clamping block, or a belt locking mechanism, a clamping locking mechanism, etc. The opening of the open clamping ring can be adjusted to facilitate the sleeving of the sleeve, and the angle of the crank on the sleeve can be finely adjusted for precise synchronization.

[0047] As shown in the drawings of this embodiment, a swing arm 30 is radially extended on the open clamping ring corresponding to the pickup block in the middle. The swing arm 30 is longitudinally aligned with the crank 39 but circumferentially offset. The pickup driving mechanism drives the swing arm 30 to swing to rotate the pickup block. This is a structural design of offsetting the crank and the swing arm on the open clamping ring. From the perspective of stress, it can share the excessive wear of the crank. In other embodiments, the crank corresponding to the middle pickup block can be directly used as a swing arm, that is, the connecting rod is rotatably connected to the crank. No additional swing arm is designed, which reduces the number of components, is conducive to production, reduces costs, and also reduces the interference of too many components on the open clamping ring to the sheet taking and placing.

[0048] In order to facilitate the installation of the pickup block on the sleeve, the pickup block 33 is a rectangular plate structure in this embodiment. One side of the rear part of the pickup block 33 is provided as a mounting surface, and the sleeve is provided with a mounting surface that is matched with the mounting surface. The other side 331 of the rear part of the pickup block is provided with two or more mounting structures in the longitudinal direction at the position corresponding to the mounting surface, for detachably mounting the pickup block on the sleeve. Thus, the pickup block can be replaced and adjusted for different sizes of the sheet material, or repaired after the pickup block is damaged. The mounting structure can be a screw and screw hole type mounting structure. The longitudinally arranged mounting structure can enable the pickup block to be more stably mounted on the sleeve.

[0049] The embodiment also optimizes the separation of the sheet material in the loading frame, including a separation mechanism 7 for separating the sheet material 9 arranged in the loading frame 5 at the first sheet position. The separation mechanism 7 includes a separation driving mechanism, a separation bracket 71, and a nozzle 72 arranged on the separation bracket 71 to blow liquid or gas towards the loading frame. The separation driving mechanism drives the separation bracket 71 to move transversely relative to the loading frame so that the nozzle 72 is directed towards the first sheet position and the second sheet position of the sheet material in the loading frame. The adhered sheet material is effectively separated by gas or liquid. The separation driving mechanism can adopt a mechanism in which a motor cooperates with a screw rod assembly. The screw rod nut seat drives the bracket to move, and the stability is further guaranteed, and the driving force is relatively small.

[0050] The separation bracket 71 includes longitudinal two-side vertical rods 711 corresponding to the loading frame, and a longitudinal rod 712 connected to the longitudinal two-side vertical rods 711. The longitudinal rod 712 is sleeved on the longitudinal two-side vertical rods 711 through a sliding sleeve 713. The nozzle 72 is arranged on the longitudinal rod and can move up and down to adjust the position through the sliding sleeve, so that when the loading frame carries sheet materials of different sizes, the position of the longitudinal rod and the position of the nozzle can be adjusted through the sliding sleeve, so that the separation effect is optimal. The sliding sleeve is a sleeve structure matched with the two-side vertical rods 711, which is simple and practical.

[0051] The nozzle 72 is a rectangular block, and one side of the rectangular block facing the inside of the feeding frame is provided with a spray hole. The nozzle structure of the rectangular block is simple and practical, and the design can be more beneficial to installation. Meanwhile, the inside of the rectangular block is smooth, which can also play a certain effect of limiting the side edges of the sheet material. The nozzle 72 is provided with a building block 73, which has a limiting strip 731 extending longitudinally towards the inside of the feeding frame for limiting the lateral position of the sheet material separated from the first sheet. The root of the building block limiting strip has a vertically extending mounting strip 732, which is provided with a stepped surface. The mounting strip is mounted on the nozzle by the stepped surface and the outer contour of the nozzle rectangular block. Thus, the limiting strip can be quickly and accurately installed based on the rectangular block nozzle as the installation reference, which is convenient for combination and replacement. Compared with the conventional nozzle, the structure is optimized and has better practicality. In order to protect the sheet material, one side of the limiting strip 731 facing the first sheet material is provided with a mounting hole 733. In the embodiment, the mounting hole 733 is a through hole, and in other embodiments, a blind hole can be used. A soft pad for protecting and buffering the sheet material is mounted in the mounting hole. The soft pad can be selected from a silica gel pad or a rubber pad. The soft pad mounted in the mounting hole can be easily replaced, and the structure is simple and practical.

The above embodiment description is only used to help understand the core idea of the present application.
