Description

Technical Field

[0001] The utility model belongs to the technical field of silicon rod fetching equipment, and particularly relates to a multi-station fetching device. Background Art

[0002] The multi-station cutting equipment plays an indispensable role in the process of silicon crystal rod production. That is, the multi-station cutting equipment can not only improve the cutting efficiency of silicon crystal rods, but also provide structural support for the staff to cut different sheets at multiple positions of the silicon crystal rod in the subsequent silicon crystal rod quality inspection work, so that the final inspection results can be more authentic with the support of multiple sets of experimental data.

[0003] However, in the actual process of taking slices, it was found that the existing slice taking equipment has certain limitations in the slice taking method and equipment structure. For example, the slice taking and unloading mechanism of the cutting machine disclosed in the Chinese utility model patent with application number 202220356378.5 needs to first adsorb the suction cups on both ends of the silicon crystal rod when cutting the material, and then cut the material downwards. After the cutting is completed, the cut material is taken out by the suction cups. This type of slice taking and unloading device is not only unable to take the slices in the middle, but also can only take one slice at a time, which will seriously affect the overall production efficiency.

[0060] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0061] The most critical concept of the utility model is that: the vacuum material picking component is driven to move in a directional manner by the Y-axis displacement mechanism, so that the vacuum material picking component can be moved between any two adjacent cutting positions; and adsorption ends are respectively provided at both ends of the vacuum material picking component, so that after the vacuum material picking component is moved between the two cutting positions, it has the ability to simultaneously adsorb the sheets on the two cutting positions, thereby improving the overall sheet picking efficiency.

[0062] Please refer to Figures 1 to 8 The multi-station film taking device 1 provided by the utility model comprises a film taking device 1;

[0063] The sheet picking device 1 is provided with a Y-axis displacement mechanism 2 whose moving direction is perpendicular to the axial direction of the bar to be processed;

[0064] A vacuum material taking component 3 is provided on the movable part of the Y-axis displacement mechanism 2;

[0065] In the X-axis direction, both ends of the vacuum material taking component 3 are provided with adsorption ends;

[0066] The suction end can be moved to between two adjacent cutting positions and / or sheets on the bar material to be processed.

[0067] Specifically, the Y-axis displacement mechanism 2 is any commercially available device that can drive an object to move in a straight line, such as a pneumatic guide rail, a linear guide rail, etc. The Y-axis displacement mechanism 2 of the utility model adopts a connection block arranged on the belt of the pulley transmission system, and then the vacuum material taking component 3 is connected to the connection block, so that the vacuum material taking component 3 is synchronously driven to move by the movement of the belt.

[0068] From the above description, it can be seen that the beneficial effects of the utility model are: providing a multi-station film picking device, which drives the vacuum material picking component 3 to move in a directional manner through the Y-axis displacement mechanism 2, so as to provide structural support for the vacuum material picking component 3 to be able to move between any two adjacent cutting positions in the future; and adsorption ends are respectively arranged at both ends of the vacuum material picking component 3, so that after the vacuum material picking component 3 moves between the two cutting positions, it has the ability to simultaneously adsorb the film materials on the two cutting positions; compared with the existing film picking device 1, the existing film picking device 1 can only be arranged at the head and tail ends of the silicon crystal rod due to structural limitations, so it can only intercept the film materials at the head and tail ends of the silicon crystal rod, so that the subsequent detection results cannot truly reflect the quality of the silicon crystal rod; if the existing film picking device 1 is forcibly When it is used for taking slices from the middle of a silicon crystal rod or taking slices from any cutting position, it is necessary to change the corresponding sequence of slice taking operations, that is, after taking slices from the head and tail ends, it is necessary to further take slices from multiple cutting positions in the middle section, and the section material in front of the corresponding cutting position needs to be removed in sequence before the slice material on the cutting position can be taken, which will seriously affect the overall slice taking efficiency; the slice taking device 1 of the present invention adjusts the corresponding slice taking idea, and adjusts the existing "slice taking device 1 looking for slice material" to "sheet material looking for slice taking device 1", which overcomes the defect that the existing slice taking device 1 can only be fixed at the head and tail ends of the silicon crystal rod, so that the slice taking device 1 can be moved between the slices on the two cutting positions to be taken, thereby simultaneously adsorbing the two slices to improve the overall slice taking efficiency.

[0069] Furthermore, the vacuum material taking component 3 includes a connecting frame 31, an adsorption component 32 and a vacuum generation controller 33;

[0070] The adsorption assembly 32 and the vacuum hole generator are both connected to the movable part of the Y-direction displacement mechanism 2 through the connecting frame 31;

[0071] The adsorption assembly 32 is electrically connected to the vacuum generation controller 33;

[0072] In the X-axis direction, both ends of the adsorption component 32 are provided with adsorption ends.

[0073] From the above description, it can be seen that the design has made specific modifications to the composition structure of the vacuum material picking component 3, integrating the vacuum material picking component 3 and the core structure on the connecting frame 31, and the Y-axis displacement mechanism 2 synchronously drives the adsorption component 32 and the vacuum generation controller 33 to move, which can effectively compress the size of the equipment and avoid the need for additional corresponding space due to the separation of equipment, as well as the difficulty of line layout.

[0074] Further, the adsorption assembly 32 includes a vacuum adjustment chamber 321 and a suction cup group 322;

[0075] In the X-axis direction, suction cup groups 322 are provided at both ends of the vacuum adjustment chamber 321;

[0076] The suction end of the suction cup group 322 is arranged toward the end away from the vacuum adjustment chamber 321;

[0077] The vacuum adjustment chamber 321 is electrically connected to the vacuum generation controller 33 .

[0078] Furthermore, in the X-axis direction, distance sensors are provided at both ends of the vacuum adjustment chamber 321;

[0079] The direction of the sensing end of the distance sensor is consistent with the direction of the adsorption end of the suction cup group 322;

[0080] The distance sensor and the vacuum generation controller 33 are electrically connected.

[0081] As can be seen from the above description, the design further optimizes the composition structure of the adsorption component 32. When in use, the distance sensor will also be connected to the peripheral cutting equipment to ensure that the distance between the intercepted sheet and the suction cup group 322 can be detected in real time when the material is taken, so as to avoid the sheet from generating a large impact force when it contacts the suction cup group 322 due to the inability to sense the distance, thereby causing damage to the sheet and affecting the subsequent detection work; that is, when the distance sensor detects that the sheet is about to approach the suction cup group 322, the peripheral cutting equipment is controlled to reduce the speed of the sheet approaching the suction cup group 322 until the sheet collides with the suction cup group 322, and then the vacuum generation controller 33 starts the vacuum adjustment chamber 321 to perform the sheet adsorption work, so as to ensure the reliability and stability of the sheet adsorption.

[0082] Furthermore, the above-mentioned multi-station film-taking device 1 further includes a Y-direction sensor 4;

[0083] In the Y-axis direction, the Y-direction sensor 4 is arranged at one end of the vacuum regulating chamber 321 close to the bar to be processed.

[0084] Furthermore, the above-mentioned multi-station film-taking device 1 further includes an X-direction sensor 5;

[0085] In the X-axis direction, X-direction sensors 5 are provided at both ends of the connecting frame 31 .

[0086] Specifically, the Y-direction sensor 4 and the X-direction sensor 5 are any commercially available devices capable of detecting whether there is an object in the moving direction, such as an infrared sensor or a laser radar sensor.

[0087] As can be seen from the above description, this design can effectively improve the safety of the vacuum material taking component 3 during use. When in use, the Y-direction sensor 4 and the X-direction sensor 5 are connected to the peripheral control device, so that when the vacuum material taking component 3 moves, if an object is detected, or if a corresponding device is approaching the vacuum material taking component 3, the corresponding deceleration signal can be transmitted to the peripheral control device to reduce the moving speed of the vacuum material taking component 3 or other devices, or directly stop the corresponding device to avoid collision between devices and damage to the device, thereby increasing additional equipment maintenance costs.

[0088] Furthermore, the above-mentioned multi-station film taking device 1 also includes a material receiving device 6;

[0089] The material receiving device 6 comprises a support frame 61 and a material receiving mechanism 62 slidably connected to the support frame 61;

[0090] There is an intersection between the moving direction of the material receiving mechanism 62 and the moving direction of the suction end of the vacuum material taking component 3 .

[0091] From the above description, it can be seen that the design has made specific improvements to the composition structure of the multi-station film picking device 1. By setting the corresponding material receiving mechanism 62 and ensuring that there is an intersection between the moving direction of the material receiving mechanism 62 and the moving direction of the adsorption end of the vacuum material picking component 3, the film adsorbed by the vacuum material picking component 3 can be transferred to the material receiving mechanism 62 at the intersection, thereby realizing the automatic unloading function of the film to save the corresponding manual unloading cost.

[0092] Furthermore, a displacement driving mechanism 611 is provided on the support frame 61;

[0093] The material receiving mechanism 62 is connected to the movable end of the displacement driving mechanism 611;

[0094] There is an intersection between the moving direction of the displacement driving mechanism 611 and the moving direction of the adsorption end of the vacuum material taking component 3 .

[0095] Specifically, the displacement drive mechanism 611 is any commercially available device that can drive an object to move in a straight line, such as a linear guide, a pneumatic guide, or a component in which a lead screw is driven by a motor. The displacement drive mechanism 611 in the utility model is preferably a combination of a rack 7 and a motor 8 with a gear at the movable end, that is, a rack 7 whose extension direction intersects with the moving direction of the suction end of the vacuum material taking component 3 is provided on the support frame 61, and then the motor 8 is connected to the movable part of the displacement drive mechanism 611, and the gear on the movable end of the motor 8 is meshed with the rack 7, so that under the action of the gear and the rack 7, the movable part of the displacement drive mechanism 611 is driven to move back and forth along the extension direction of the rack 7.

[0096] Furthermore, the material receiving mechanism 62 includes a material receiving box 621, a support seat 622, a guide frame 623 and a lifting assembly 624;

[0097] The guide frame 623 and the lifting assembly 624 are both connected to the movable part of the displacement driving mechanism 611;

[0098] A guide rail 6231 is provided on the guide frame 623, and the extension direction of the guide rail 6231 is parallel to the movement direction of the lifting assembly 624;

[0099] The receiving box 621 is connected to the movable part of the lifting assembly 624 through the support seat 622;

[0100] The support seat 622 is slidably connected to the guide frame 623 via the guide rail 6231;

[0101] When the suction end of the vacuum material taking component 3 and the material receiving box 621 both reach the intersection, the vertical projection of the suction end of the vacuum material taking component 3 is located in the opening area of ​​the material receiving box 621 .

[0102] As can be seen from the above description, the design has made specific modifications to the component structure of the material receiving mechanism 62. When the adsorption end of the vacuum material picking component 3 and the material receiving box 621 both reach the intersection, the lifting component 624 drives the material receiving box 621 to move toward the vacuum material picking component 3, which can provide structural support for the sheet material to be smoothly transferred to the inside of the material receiving box 621; at the same time, during the lifting process, because the guide frame 623 is provided with a guide rail 6231, the movement stability of the material receiving box 621 can be improved, and the problem of the sheet material in the material receiving box 621 being easily worn due to shaking, which affects the subsequent detection results; and the displacement drive mechanism 611 drives the material receiving box 621 to adjust the material receiving position, so that the sheet material can be arranged in the material receiving box 621 in an orderly manner, thereby improving the overall material receiving efficiency.

[0103] Furthermore, a limiting hole is provided on the outer bottom surface of the receiving box 621;

[0104] The bottom of the support seat 622 is provided with a limiting column 6221 matched with the limiting hole.

[0105] From the above description, it can be seen that after the material receiving box 621 is filled with sheet materials, the displacement driving mechanism 611 needs to further move the material receiving box 621 to the specified position, and at the same time, corresponding limit holes and limit columns 6221 are respectively provided on the material receiving box 621 and the support seat 622, so as to avoid the material receiving box 621 from continuing to move due to inertia when moving to the specified position, thereby easily causing the risk of the material receiving box 621 falling off the support seat 622.

[0106] The multi-station wafer taking device 1 of the utility model can assist in the wafer taking work of silicon crystal rod wafers, and can be applied to a cutting mechanism of a multi-station cutting machine disclosed in the existing Chinese utility model patent with application number 202023080931.7. By changing the equipment action sequence, the support component is used to drive the cut multi-segment silicon rods to move, and drive the adjacent silicon rods toward the adsorption component 32. After the adsorption component 32 is adsorbed on the surface of the silicon rod, the cutting mechanism slices the wafers, thereby completing the wafer taking work of the multi-cutting position wafers.

[0107] The utility model is particularly suitable for a gear train device, which is installed on a peripheral moving mechanism so that the gear train device 10 can move along the axial and vertical directions of the rod material. The gear train device 10 is arranged relative to a transmission wheel frame in a multi-station cutting machine disclosed in the Chinese utility model patent with application number 202023080931.7; when the silicon rod is placed on the transmission wheel frame for cutting, it can be supported by a support assembly in a multi-station cutting machine disclosed in the Chinese utility model patent with application number 202023080931.7; the cutting gear train 10 is provided with two cutting wire saws wound around the driving wheel, the driven wheel and the tensioning wheel for cutting For cutting silicon rods, reference may be made to a silicon rod cutting mechanism disclosed in the Chinese utility model patent with application number 202021635886.4, and the gear train device 10 also includes two symmetrically arranged wafer holding devices 101; the wafer holding device 101 includes a guide rail 102, a locker 103, and a displacement assembly 104 and a clamp 105 connected in sequence; the extension direction of the guide rail 102 is parallel to the cutting direction of the gear train device 10; the displacement assembly 104 is slidably connected to the guide rail 102; the locking portion of the locker 103 is located on the moving path of the displacement assembly 104; the displacement assembly 104 can drive the clamp 105 to reciprocate along the radial direction of the rod to be processed. Specifically, the locker 103 is any commercially available device that can lock an object, and the locker 103 of the utility model is preferably an electromagnetic adsorption device, such as an electromagnet. This design makes specific improvements to the composition structure of the wheel train device 10 and the sheet holding device 101. By arranging a locker 103 in the moving path of the displacement component 104, the sheet holding device 101 can be coupled with the wheel train device 10 for synchronous movement before reaching the specified sheet holding position, and can be decoupled from the wheel train device 10 for relative movement after reaching the sheet holding position. Structural support is provided, thereby completing the clamping work of the sheet material synchronously without interfering with the normal cutting work of the wheel train device 10; and in order to enable the clamp 105 to better fit the outer cylindrical surface of the sheet material, the clamping surface of the clamp 105 can be designed as an arc surface, so that the clamping surfaces of the two relatively arranged clamps 105 can form a virtual circular clamping surface, thereby increasing the effective contact area between the clamp 105 and the sheet material to avoid the problem of overturning during the clamping process.

[0108] Compared with the existing film picking equipment, the existing film picking device, even if combined with the wheel system device 10 provided with the film holding device 101, can only absorb one sheet of material at a time; while the film picking device of the utility model, after being combined with the wheel system device 10 provided with the film holding device 101, can absorb two sheets of material at the same time in one film picking operation, thereby effectively improving the overall film picking efficiency.

[0109] Please refer to Figures 1 to 8 , Embodiment 1 of the present utility model is:

[0110] A multi-station film picking device comprises a film picking device 1, a Y-axis sensor 4, an X-axis sensor 5 and a material receiving device 6; the film picking device 1 is provided with a Y-axis displacement mechanism 2 whose moving direction is perpendicular to the axial direction of a bar material to be processed; a vacuum material picking component 3 is provided on the movable part of the Y-axis displacement mechanism 2; in the X-axis direction, both ends of the vacuum material picking component 3 are provided with suction ends; the suction ends can be moved to two adjacent cutting positions on the bar material to be processed and / or between the sheets.

[0111] The vacuum material picking component 3 includes a connecting frame 31, an adsorption component 32 and a vacuum generating controller 33; the adsorption component 32 and the vacuum generating hole device are connected to the movable part of the Y-axis displacement mechanism 2 through the connecting frame 31; the adsorption component 32 and the vacuum generating controller 33 are electrically connected; in the X-axis direction, both ends of the adsorption component 32 are provided with adsorption ends; the adsorption component 32 includes a vacuum regulating chamber 321 and a suction cup group 322; in the X-axis direction, both ends of the vacuum regulating chamber 321 are provided with suction cup groups 322; the adsorption end of the suction cup group 322 is set toward the end away from the vacuum regulating chamber 321; the vacuum regulating chamber 321 is electrically connected to the vacuum generating controller 33.

[0112] In the X-axis direction, distance sensors are provided at both ends of the vacuum regulating chamber 321 ; the direction of the sensing end of the distance sensor is consistent with the direction of the adsorption end of the suction cup group 322 ; the distance sensor is electrically connected to the vacuum generation controller 33 .

[0113] In the Y-axis direction, the Y-direction sensor 4 is arranged at one end of the vacuum regulating chamber 321 close to the bar to be processed; in the X-axis direction, X-direction sensors 5 are arranged at both ends of the connecting frame 31.

[0114] The material receiving device 6 includes a support frame 61, and a material receiving mechanism 62 and a displacement driving mechanism 611 slidably connected to the support frame 61; the material receiving mechanism 62 is connected to the movable end of the displacement driving mechanism 611; the moving direction of the displacement driving mechanism 611 and the moving direction of the suction end of the vacuum material taking component 3 have an intersection; the material receiving mechanism 62 includes a material receiving box 621, a support seat 622, a guide frame 623 and a lifting component 624; the guide frame 623 and the lifting component 624 are both connected to the movable part of the displacement driving mechanism 611; a guide rail 6231 is provided on the guide frame 623 , and the extension direction of the guide rail 6231 is parallel to the moving direction of the lifting assembly 624; the material receiving box 621 is connected to the moving part of the lifting assembly 624 through the support seat 622; the support seat 622 is slidably connected to the guide frame 623 through the guide rail 6231; when the adsorption end of the vacuum material picking assembly 3 and the material receiving box 621 both reach the intersection, the vertical projection of the adsorption end of the vacuum material picking assembly 3 is located in the opening area of ​​the material receiving box 621; a limiting hole is provided on the outer bottom surface of the material receiving box 621; a limiting column 6221 adapted to the limiting hole is provided at the bottom of the support seat 622.

[0115] The working principle of the utility model is as follows: when the peripheral cutting device cuts off the silicon crystal rod at the corresponding cutting position and cuts out the sheet material and resets it, the cut sheet material is taken out at the same time; at this time, the Y-axis displacement mechanism 2 drives the vacuum material taking component 3 to move between the two cutting devices until the suction end of the suction cup group 322 is facing the sheet material; then, the peripheral cutting device drives the sheet material to move to the suction end of the corresponding suction cup group 322, and the distance sensor monitors the distance between the sheet material and the suction cup group 322 in real time. When the sheet material is about to approach the suction cup group 322, the peripheral device is lowered. The moving speed of the cutting equipment is increased until the sheet lightly rests on the adsorption end of the suction cup group 322; at this time, the vacuum adjustment chamber 321 is started by the vacuum generating controller 33 to adsorb two sheets at the same time; then, the Y-axis displacement mechanism 2 drives the sheet to move to the receiving box 621. When the sheet reaches the specified position, the lifting component 624 is started to make the receiving box 621 rise to the specified position, and the vacuum generating controller 33 is turned off. At this time, the sheet falls into the receiving box 621 under the action of gravity; finally, the receiving box 621 is reset to complete the sheet removal work.

[0116] In summary, the utility model provides a multi-station film picking device, which drives the vacuum material picking component to move in a directional manner through the Y-axis displacement mechanism, so as to provide structural support for the vacuum material picking component to be able to move between any two adjacent cutting positions in the future; and adsorption ends are respectively arranged at both ends of the vacuum material picking component, so that after the vacuum material picking component is moved between the two cutting positions, it has the ability to simultaneously adsorb the films on the two cutting positions; compared with the existing film picking device, the existing film picking device can only be arranged at the head and tail ends of the silicon crystal rod due to structural limitations, so it can only intercept the films at the head and tail ends of the silicon crystal rod, so that the subsequent detection results cannot truly reflect the quality of the silicon crystal rod; if the existing film picking device is forcibly used for film picking in the middle of the silicon crystal rod or in any cutting position film picking scenario, it is necessary to change the corresponding film picking operation sequence, that is, after taking the films at the head and tail ends, it is necessary to further adjust the middle section. When taking slices at multiple cutting positions, it is necessary to take down the sections of material in front of the corresponding cutting position in turn before taking the slices at the cutting position, which will seriously affect the overall taking efficiency. The slice taking device of the utility model adjusts the corresponding taking idea, and adjusts the existing "slice taking device looking for slice material" to "slice material looking for slice taking device", that is, it overcomes the defect that the existing slice taking device can only be fixed at the head and tail ends of the silicon crystal rod, so that the slice taking device can be moved between the slices on the two cutting positions to be taken, thereby simultaneously adsorbing the two slices to improve the overall taking efficiency. At the same time, by setting a corresponding material receiving mechanism and ensuring that there is an intersection between the moving direction of the material receiving mechanism and the moving direction of the adsorption end of the vacuum material taking component, the slice adsorbed by the vacuum material taking component can be transferred to the material receiving mechanism at the intersection, thereby realizing the automatic unloading function of the slice material to save the corresponding manual unloading cost.
