Description

Technical Field

[0001] This application relates to the technical field of material ornaments, and particularly to a material ornament device and an ornament method. Background Art

[0002] The main function of a material ornament device is to place and arrange materials according to certain rules and requirements. It is widely used in multiple industries, which can improve the sorting efficiency of materials and save labor.

[0003] In the prior art, a material ornament device mainly grabs materials through a clamping mechanism (such as a clamping jaw cylinder, etc.) to achieve the transfer of materials, so that the materials can be placed regularly according to the set requirements. However, when placing ornaments for plate-shaped materials, since the thickness of such materials is relatively thin and the clamping surface that can be provided is small, the grabbing effect is not ideal, and there is a situation where the materials accidentally fall off during the transfer process, resulting in poor stability. In addition, for materials with fragile structures, the clamping and grabbing method is also likely to cause clamping damage to the side walls of the materials. Therefore, there is an urgent need for a material ornament device suitable for grabbing plate-shaped materials to improve the stability of material ornamentation and reduce the possibility of accidental falling off of materials during the transfer process. Summary of the Invention

[0004] In order to improve the stability of material ornamentation, this application provides a material ornament device and an ornament method.

[0005] In a first aspect, a material ornament device provided by this application adopts the following technical solution: A material ornament device includes a mounting frame, a transfer seat, a transfer mechanism, and a grabbing mechanism. A storage table and a conveyor belt are respectively arranged at the bottom of the mounting frame; the transfer seat is slidably mounted on the mounting frame, and the transfer mechanism is arranged on the mounting frame to drive the transfer seat to reciprocally slide between the storage table and the conveyor belt; the grabbing mechanism includes a suction head and a supporting component for supporting the material, and the suction head is slidably mounted on the transfer seat to be able to move up and down.

[0006] By adopting the above technical solution, when placing ornaments for materials, the transfer mechanism slides the transfer seat above the storage table, and then drives the suction head to move down so that the suction head can perform negative pressure adsorption on the materials on the storage table to grab the materials, thereby being able to transfer the materials and place them on the conveyor belt for outward output. After the suction head performs negative pressure adsorption on the materials, during the transfer process, the supporting component supports the lower surface of the materials to improve the firmness of grabbing the materials and reduce the possibility of accidental falling off of the materials during the transfer process, thereby improving the stability during the material ornamentation process.

[0007] Optionally, a lifting block is slidably mounted on the side wall of the transfer base, and the suction head is arranged at the bottom of the lifting block; a lifting cylinder is arranged on the transfer base, the cylinder body of the lifting cylinder is connected to the transfer base, and the piston rod of the lifting cylinder is connected to the lifting block.

[0008] By adopting the above technical solution, the lifting of the suction head is realized by controlling the telescopic movement of the piston rod of the lifting cylinder, so as to facilitate the suction and grasping of the material by the suction head.

[0009] Optionally, the supporting assembly includes swing rods and a first spring. There are two swing rods, and the two swing rods are symmetrically distributed on both sides of the lifting block. Each swing rod is hinged to the side wall of the transfer base; a supporting block is connected to the lower end of each swing rod, and the first spring is arranged between the two swing rods. In the normal state, the first spring forces the supporting blocks of the two swing rods to move away from each other; a guide wheel is rotatably connected to the side wall of each swing rod, and the side wall of the lifting block has a guide surface for the guide wheel to abut against. When the lifting block rises, the lifting block forces the supporting blocks of the two swing rods to approach each other through the guide surface to support the lower surface of the material.

[0010] By adopting the above technical solution, after the suction head moves to the upper part of the storage table, the lifting cylinder is driven to drive the lifting block to move downward. During the downward movement of the lifting block, the upper ends of the two swing rods approach each other under the action of the first spring, so that the supporting blocks of the two swing rods move away from each other to avoid the suction head, enabling the suction head to move downward and adsorb the upper surface of the material. After the suction head adsorbs the material, the lifting block is driven to rise. During the rising process of the lifting block, the lower ends of the two swing rods are forced to approach each other through the guide surface, so that the supporting blocks can support the lower surface of the material, improving the grasping stability of the material.

[0011] Optionally, a sliding block is slidably mounted on the mounting frame. The transfer mechanism includes a fixed rack, a movable gear, a movable rack and a driving member. The fixed rack is arranged on the side wall of the mounting frame, the movable gear is rotatably connected to the sliding block, the movable rack is slidably mounted on the side wall of the mounting frame and is connected to the transfer base, and meshing transmissions are provided between the fixed rack and the movable gear and between the movable rack and the movable gear; the driving member is arranged on the mounting frame to drive the sliding block to reciprocate along the length direction of the fixed rack.

[0012] By adopting the above technical solution, the driving member is used to drive the sliding block to reciprocate, so that the fixed rack and the moving gear, and the moving rack and the moving gear are engaged to drive the transfer seat to reciprocate between the storage table and the conveyor belt. In cooperation with the lifting of the suction head, the materials on the storage table are transferred and placed on the conveyor belt one by one, improving the operation convenience of the overall structure. The combination of the fixed rack, the moving gear and the moving rack can achieve the effect of "range extension", enabling the transfer seat to reciprocate between the storage table and the conveyor belt.

[0013] Optionally, a rotating shaft is rotatably installed on the side wall of the installation frame. The driving member includes a first connecting rod, a second connecting rod and a driving motor. One end of the first connecting rod is connected to the rotating shaft, one end of the second connecting rod is hinged to the end of the first connecting rod away from the rotating shaft, and the other end is hinged to the sliding block; the driving motor is arranged on the installation frame to drive the rotating shaft to rotate.

[0014] By adopting the above technical solution, the driving motor drives the rotating shaft to rotate. Under the action of the first connecting rod and the second connecting rod, the sliding block can reciprocate along the length direction of the fixed rack, so as to realize the reciprocating sliding of the transfer seat between the storage table and the conveyor belt.

[0015] Optionally, the installation frame has a first interval and a second interval. The storage table is located below the first interval, and the conveyor belt is located below the second interval; a translation seat is slidably installed on the transfer seat, and the translation seat is in the same sliding direction as the transfer seat. The suction head is arranged on the translation seat; a second spring is arranged between the translation seat and the transfer seat. When the transfer seat slides to the first interval, the second spring forces the translation seat to face the storage table; a limit seat for the translation seat to abut against is slidably installed in the second interval, and the installation frame is provided with an adjustment assembly for adjusting the distance between the limit seat and the translation seat.

[0016] By adopting the above technical solution, the distance between the limit seat and the translation seat is adjusted by the adjustment assembly, so as to control the maximum sliding amount when the translation seat slides from the first interval to the second interval, that is, the position where the translation seat enters the second interval each time can be controlled, and then the specific position of the suction head in the second interval can be adjusted, so that the position where the suction head enters the second interval each time can be different, thus realizing the sequential arrangement of multiple materials along the width direction of the conveyor belt according to the design requirements.

[0017] Optionally, a rotating shaft is rotatably installed on the side wall of the installation frame, and a rotating rod is rotatably installed on the side wall of the installation frame. The rotating rod and the rotating shaft are circumferentially linked; the adjusting assembly includes a rotating lead screw and a linkage member. The rotating lead screw is rotatably connected to the side wall of the installation frame, and both ends of the rotating lead screw extend along the sliding direction of the transfer seat. The rotating lead screw passes through the limit seat and is threadedly connected to the limit seat; the linkage member is arranged between the rotating rod and the rotating lead screw to drive the rotating rod and the rotating lead screw to rotate synchronously.

[0018] By adopting the above technical solution, the circumferential linkage between the rotating rod and the rotating shaft enables the rotating shaft to drive the rotating rod to rotate synchronously when the transfer seat slides. Under the action of the linkage member, the rotating lead screw is driven to rotate synchronously, so that the limit seat can approach or move away from the translation seat, thereby changing the maximum sliding amount when the translation seat slides from the first interval to the second interval. The position where the suction head moves into the second interval each time can be different, realizing the arrangement of multiple materials along the width direction of the conveyor belt according to the design requirements, and improving the operation convenience of the overall structure.

[0019] Optionally, a switching seat is arranged on the side wall of the installation frame. A first gear and a second gear are respectively rotatably installed in the switching seat. The first gear and the second gear are meshed and driven. The first gear is sleeved on the outer peripheral wall of the rotating shaft, and the second gear is sleeved on the outer peripheral wall of the rotating rod.

[0020] By adopting the above technical solution, the meshing drive between the first gear and the second gear realizes the circumferential linkage between the rotating shaft and the rotating rod, that is, when the rotating shaft rotates, it can drive the rotating rod to rotate synchronously.

[0021] Optionally, the switching seat is slidably installed on the installation frame to be able to slide along the axial direction of the rotating shaft; a plurality of first gears are arranged along the axial direction of the rotating shaft, and the outer diameters of the first gears are different; a plurality of second gears are arranged along the axial direction of the rotating rod, and the outer diameters of the second gears are different; the plurality of first gears and the plurality of second gears are arranged correspondingly, and each first gear and the corresponding second gear are meshed and driven; docking strips are arranged on the inner peripheral walls of the first gear and the second gear, and docking heads are arranged on the end faces of the rotating shaft and the rotating rod. Docking grooves for the docking strips to be inserted into are formed in the docking heads.

[0022] By adopting the above technical solution, a plurality of first gears and second gears are correspondingly arranged. In actual operation, the position of the switching seat can be controlled to embed the first gear and the corresponding second gear into the installation positions (the installation positions refer to: the docking strip of the first gear is embedded into the docking groove of the docking head of the rotating shaft, and the docking strip of the corresponding second gear is embedded into the docking groove of the docking head of the rotating rod), so as to realize the circumferential linkage between the rotating shaft and the rotating rod. By connecting different groups of first gears and second gears to the docking heads, the transmission ratio between the rotating shaft and the rotating rod can be changed, so as to control the rotation amount of the rotating lead screw, that is, control the sliding amount of the limiting seat, so as to change the distance between two adjacent materials in the width direction of the conveyor belt according to actual needs, and improve the flexibility of the overall structure.

[0023] In a second aspect, a material placement method provided by the present application adopts the following technical solution: A material placement method specifically includes the following steps: S1. Feeding: Stacking a certain number of materials on the storage table; S2. Placing: Placing the materials on the conveyor belt according to the set requirements; S3. Discharging.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the settings of the suction head and the supporting component, when placing the materials, the transfer mechanism is used to slide the transfer seat above the storage table, and then the suction head is driven to move downward so that the suction head can perform negative pressure adsorption on the materials on the storage table to grab the materials, so as to transfer and place the materials on the conveyor belt for outward output. After the suction head performs negative pressure adsorption on the materials, during the transfer process, the lower surface of the materials is supported by the supporting component, improving the stability of grabbing the materials and reducing the possibility of accidental dropping of the materials during the transfer process, thereby improving the stability during the material placement process; 2. Through the settings of the fixed rack and the movable rack, the driving member is used to drive the sliding block to reciprocate, so that the fixed rack and the movable gear, and the movable rack and the movable gear are engaged to drive the transfer seat to reciprocate between the storage table and the conveyor belt, and cooperate with the lifting of the suction head to transfer and place the materials on the storage table on the conveyor belt one by one, improving the operation convenience of the overall structure. The combination of the fixed rack, the movable gear and the movable rack can achieve the effect of "increasing the stroke" so that the transfer seat can reciprocate between the storage table and the conveyor belt; 3. By adjusting the settings of the adjustment component, the distance between the limit seat and the translation seat is adjusted through the adjustment component, so as to control the maximum sliding amount when the translation seat slides from the first interval to the second interval. That is, the position of the translation seat when it moves into the second interval each time can be controlled, and then the specific position of the suction head in the second interval can be adjusted, so that the position of the suction head when it moves into the second interval each time can be different, thereby realizing the sequential arrangement of multiple materials along the width direction of the conveyor belt according to the design requirements.

[0027] The following is combined with Figures 1 - 7A further detailed description of the present application is provided.

[0028] Embodiment 1: The embodiment of the present application discloses a material display device.

[0029] Refer to Figure 1 、 Figure 2 A material display device includes a mounting frame 1, a transfer seat 2, a transfer mechanism 3, and a grasping mechanism 4. The mounting frame 1 is in a long strip shape. Along its own length direction, a first interval 13 and a second interval 14 are successively formed on the mounting frame 1. A storage table 5 and a conveyor belt 6 are respectively installed at the bottom of the mounting frame 1. The storage table 5 is located below the first interval 13 for stacking materials, and the conveyor belt 6 is located below the second interval 14 for receiving materials.

[0030] A first slide rail 17 is fixedly installed on the side wall of the mounting frame 1. The two ends of the first slide rail 17 extend along the length direction of the mounting frame 1. The transfer seat 2 is slidably installed on the first slide rail 17 of the mounting frame 1; the transfer mechanism 3 is arranged on the mounting frame 1 to drive the transfer seat 2 to reciprocally slide between the first interval 13 and the second interval 14 (i.e., between the storage table 5 and the conveyor belt 6).

[0031] Refer to Figure 1 、 Figure 3 A sliding groove 18 is formed on the side wall of the mounting frame 1. The two ends of the sliding groove 18 extend along the length direction of the mounting frame 1. A sliding block 11 is slidably installed in the sliding groove 18. The transfer mechanism 3 includes a fixed rack 31, a movable gear 32, a movable rack 33, and a driving member. The length directions of the fixed rack 31 and the movable rack 33 are both consistent with the length direction of the mounting frame 1. The fixed rack 31 is fixedly installed on the side wall of the mounting frame 1. The movable gear 32 is rotatably connected to the sliding block 11; the movable rack 33 is slidably installed on the side wall of the mounting frame 1. A connecting bar 331 is installed between the movable rack 33 and the transfer seat 2, and the movable rack 33 and the transfer seat 2 are connected through the connecting bar 331. Meshing transmissions are provided between the fixed rack 31 and the movable gear 32, and between the movable rack 33 and the movable gear 32.

[0032] The driving member is arranged on the mounting frame 1 to drive the sliding block 11 to reciprocally slide along the length direction of the fixed rack 31. A rotating shaft 12 is rotatably installed on the side wall of the mounting frame 1; the driving member includes a first connecting rod 34, a second connecting rod 35, and a driving motor 36. One end of the first connecting rod 34 is fixedly connected to the rotating shaft 12. One end of the second connecting rod 35 is hinged to the end of the first connecting rod 34 away from the rotating shaft 12, and the other end is hinged to the sliding block 11; the driving motor 36 is fixedly installed on the mounting frame 1. In this embodiment, the output shaft of the driving motor 36 is coaxially connected to the rotating shaft 12.

[0033] Refer to Figure 1 、Figure 2 , the grasping mechanism 4 is arranged on the transfer seat 2 for grasping materials. The grasping mechanism 4 includes a suction head 41 and a supporting component for supporting the materials. A lifting block 21 is slidably installed on the side wall of the transfer seat 2. The suction head 41 is fixedly installed at the bottom of the lifting block 21. The suction head 41 is slidably installed on the transfer seat 2 through the lifting block 21 to be able to lift. The suction head 41 is connected with a suction pipe (not shown in the figure) for evacuating air. The transfer seat 2 is installed with a lifting cylinder 22. The cylinder body of the lifting cylinder 22 is fixedly connected to the transfer seat 2. The piston rod of the lifting cylinder 22 is connected to the lifting block 21. When the piston rod of the lifting cylinder 22 extends outwards, the lifting block 21 moves downwards.

[0034] Refer to Figure 1 , Figure 2 , in this embodiment, the lifting block 21 includes a guiding part 212 and a connecting part 213. The suction head 41 is installed at the bottom of the connecting part 213. The piston rod of the lifting cylinder 22 is connected to the guiding part 212; a lifting rod 214 is fixedly installed on the top wall of the connecting part 213. A lifting groove 215 for the sliding rod to penetrate is opened on the bottom wall of the guiding part 212. The connecting part 213 is slidably installed on the guiding part 212 through the lifting rod 214. A third spring 216 is installed in the lifting groove 215. One end of the third spring 216 is fixedly connected to the lifting rod 214, and the other end is fixedly connected to the inner wall of the lifting groove 215.

[0035] The supporting component includes swing rods 42 and a first spring 43. The number of swing rods 42 is two. The two swing rods 42 are symmetrically distributed on both sides of the lifting block 21. Each swing rod 42 is hinged to the side wall of the transfer seat 2; a supporting block 421 is fixedly installed at the lower end of each swing rod 42. The supporting block 421 is made of rubber material. The two ends of the first spring 43 are respectively fixedly installed at the upper ends of the two swing rods 42. In the normal state, the first spring 43 forces the upper ends of the two swing rods 42 to approach each other (that is, forces the supporting blocks 421 of the two swing rods 42 to move away from each other).

[0036] A guiding wheel 422 is rotatably connected to the side wall of each swing rod 42. Both sides of the guiding part 212 have guiding surfaces 211. The two guiding surfaces 211 are correspondingly arranged with the guiding wheels 422 of the two swing rods 42. The first spring 43 forces the outer peripheral walls of the guiding wheels 422 of the two swing rods 42 to abut against the corresponding guiding surfaces 211 of the guiding part 212. When the lifting block 21 is lifted, the guiding part 212 forces the supporting blocks 421 of the two swing rods 42 to approach each other through the guiding surfaces 211 to support the lower surface of the material.

[0037] Refer to Figure 1 , Figure 2, a first blocking block 217 is fixedly installed on the side wall of the connecting portion 213, and a second blocking block 24 is fixedly installed on the side wall of the transfer seat 2. When the guiding portion 212 is lifted and the guiding surface 211 of the guiding portion 212 abuts against the guiding wheel 422 of the swing rod 42, the second blocking block 24 abuts against the first blocking block 217 to form a block for the connecting portion 213; when the guiding portion 212 is continuously driven to lift, the supporting block 421 of the swing rod 42 supports the lower surface of the material.

[0038] The implementation principle of Embodiment 1 of the present application is as follows: When placing the material, the rotating shaft 12 is driven to rotate. Under the action of the first connecting rod 34, the second connecting rod 35, the fixed rack 31, the movable gear 32, and the movable rack 33, the transfer seat 2 can reciprocally slide between the first interval 13 and the second interval 14.

[0039] When the transfer seat 2 slides above the storage table 5, the suction head 41 is driven to move downward so that the suction head 41 can perform negative pressure adsorption on the material on the storage table 5 to grab the material. After the suction head 41 grabs the material, the lifting block 21 is driven to lift. During the lifting process of the guiding portion 212 of the lifting block 21, the lower ends of the two swing rods 42 are forced to approach each other through the guiding surface 211, so that the supporting block 421 can support the lower surface of the material, improving the grasping stability of the material and reducing the possibility of accidental dropping of the material during the transfer process, thereby improving the stability during the material placement process.

[0040] Embodiment 2: The present application embodiment discloses a material placement device.

[0041] The difference between the material placement device disclosed in the present application embodiment and Embodiment 1 is as follows: Referring to Figure 4 , in this embodiment, the transfer seat 2 is arranged in a long strip shape, the length direction of the transfer seat 2 is consistent with the length direction of the installation frame 1, a second slide rail 25 is fixedly installed on the side wall of the transfer seat 2, both ends of the second slide rail 25 extend along the length direction of the transfer seat 2, and a translation seat 23 is slidably installed on the second slide rail 25. In this embodiment, the suction head 41 is installed on the translation seat 23 (that is, related structures such as the lifting cylinder 22, the lifting block 21, and the swing rod 42 are all arranged on the translation seat 23).

[0042] A second spring 231 is installed between the translation seat 23 and the transfer seat 2. One end of the second spring 231 is fixedly connected to the translation seat 23, and the other end is fixedly connected to the transfer seat 2. When the transfer seat 2 slides to the first interval 13, the second spring 231 forces the suction head 41 of the translation seat 23 to be directly opposite to the storage table 5; a limit seat 15 for the translation seat 23 to abut against is slidably installed in the second interval 14, and the installation frame 1 is provided with an adjustment assembly 7 for adjusting the distance between the limit seat 15 and the translation seat 23.

[0043] Referring toFigure 4 On the side wall of the installation rack 1, a rotating rod 16 is rotatably installed. The rotating rod 16 is located below the rotating shaft 12 (the rotating shaft 12 is not shown in the figure of this embodiment). The rotating rod 16 and the rotating shaft 12 can be connected in series in the form of a belt (not shown in the figure) so that the rotating rod 16 and the rotating shaft 12 are circumferentially linked (that is, when the rotating shaft 12 rotates, it can drive the rotating rod 16 to rotate synchronously).

[0044] The adjusting assembly 7 includes a rotating lead screw 71 and a linkage member. An installation groove 19 is formed in the side wall of the installation rack 1. The two ends of the installation groove 19 extend along the length direction of the installation rack 1. The rotating lead screw 71 is rotatably installed in the installation groove 19 of the installation rack 1. The length direction of the rotating lead screw 71 is consistent with the length direction of the installation rack 1. The rotating lead screw 71 passes through the limit seat 15 and is threadedly connected to the limit seat 15 (the thread of the rotating lead screw 71 is not shown in the figure).

[0045] One end of the rotating rod 16 extends into the installation groove 19. The linkage member is arranged between the rotating rod 16 and the rotating lead screw 71 to drive the rotating rod 16 and the rotating lead screw 71 to rotate synchronously. The linkage member includes a first bevel gear 72 and a second bevel gear 73. The first bevel gear 72 is coaxially fixed to one end of the rotating rod 16, and the second bevel gear 73 is coaxially fixed to one end of the rotating lead screw 71. The first bevel gear 72 and the second bevel gear 73 are meshed. It should be noted that in this embodiment, the driving motor 36 is a servo motor (that is, the rotating shaft 12 can rotate "forward" and "backward").

[0046] The implementation principle of Embodiment 2 of this application is as follows: When the rotating shaft 12 rotates and drives the transfer seat 2 to transfer between the storage table 5 and the conveyor belt 6, under the action of the rotating rod 16, the rotating lead screw 71 can rotate synchronously to drive the limit seat 15 to slide. Every time the rotating shaft 12 rotates one circle (that is, the transfer seat 2 completes one material placement), the limit seat 15 can slide a certain distance along the length direction of the installation rack 1, so as to control the translation seat 23 to slide to the position of the second interval 14, so that the position where the translation seat 23 moves into the second interval 14 each time can be different, and then multiple materials can be sequentially placed along the width direction of the conveyor belt 6 as required.

[0047] When the limit seat 15 gradually moves from above one side of the width direction of the conveyor belt 6 to above the other side of the width direction of the conveyor belt 6, driving the rotating shaft 12 to rotate in the reverse direction can adjust the sliding direction of the limit seat 15, and cooperate with the conveying of the conveyor belt 6 to evenly place multiple materials on the surface of the conveyor belt 6, greatly improving the operation convenience of the overall structure.

[0048] Embodiment 3: This application embodiment discloses a material placement device.

The first gear 81 and the second gear 82 are meshed and driven with each other. The first gear 81 is sleeved on the outer peripheral wall of the rotating shaft 12, and the second gear 82 is sleeved on the outer peripheral wall of the rotating rod 16. The rotating shaft 12 and the rotating rod 16 are circumferentially linked through the meshing drive of the first gear 81 and the second gear 82; a through hole 87 for the rotating shaft 12 and the rotating rod 16 to penetrate is formed in the side wall of the switching seat 8.

[0050] An installation rod 9 is installed on the side wall of the installation rack 1. The axial direction of the installation rod 9 is the same as the axial direction of the rotating shaft 12. An installation ear 86 is fixedly installed on the side wall of the switching seat 8. The installation rod 9 penetrates through the installation ear 86. A locking nut 91 (the thread of the installation rod 9 is not shown in the figure) is threadedly sleeved on the outer peripheral wall of the installation rod 9. The number of the locking nuts 91 on the outer peripheral wall of the installation rod 9 is set to two. The two locking nuts 91 jointly clamp the installation ear 86 of the switching seat 8. The switching seat 8 is detachably installed on the installation rack 1 through the installation rod 9 and the locking nut 91 so as to be able to adjust the position along the length direction of the installation rod 9.
