Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire cutting, in particular to a clamping mechanism, a swing device, a feeding assembly and a wire cutting machine. BACKGROUND

[0002] The wire cutting machine is a device for cutting a workpiece through the high-speed reciprocating movement of a cutting wire. In a specific example, the diamond wire cutting machine comprises a cutting assembly and a feeding assembly, the feeding assembly being vertically movably installed on the cutting assembly, and the feeding assembly being vertically downwardly moved to realize the cutting of the workpiece installed at the bottom of the feeding assembly.

[0003] At present, the workpiece is usually installed at the bottom of the feeding assembly through a crystal holder, and the crystal holder is usually slidingly connected with a sliding groove arranged at the bottom of the feeding assembly. After the crystal holder is installed, a certain gap is formed between the crystal holder and the sliding groove. Therefore, in order to eliminate the gap, a clamping mechanism is usually arranged at the bottom of the feeding assembly. The clamping mechanism usually adopts a mode that a T-shaped rod at the bottom of a piston is vertically extended and retracted by an oil cylinder / gas cylinder to lock the crystal holder at the bottom of the feeding assembly. Although this arrangement mode can fix the crystal holder, it inevitably causes the following problems: on the one hand, in order to realize the vertical extension and retraction of the T-shaped rod, the oil cylinder / gas cylinder is vertically arranged, which to some extent increases the vertical arrangement space, resulting in the increase of the volume of the feeding assembly and the increase of the manufacturing cost. On the other hand, if a better clamping or loosening effect is required, a larger power and a larger volume of the oil cylinder / gas cylinder are required, which further increases the vertical arrangement space.

[0004] Therefore, there is a need in the art for a new technical solution to solve the above problems. SUMMARY

[0085] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0086] It should be noted that in the description of the present application, the terms of direction or position relationship indicated by the terms of "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like are based on the direction or position relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0087] In addition, it should be further pointed out that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0088] First refer to Figure 1 and Figure 4 , the swing device of the present application is described.

[0089] As Figure 1 and Figure 4 shown, in order to solve the problem of increasing manufacturing cost caused by large volume of the existing clamping mechanism 110, the clamping mechanism 110 of the present application includes a pushing part 1101, a transmission part 1102 and a clamping part 1103, the pushing part 1101 is connected with the transmission part 1102, the transmission part 1102 is connected with the clamping part 1103, the pushing part 1101 can push the transmission part 1102 to act, so that the transmission part 1102 drives the clamping part 1103 to move in a straight line direction, so as to clamp or release the crystal holder 30, the pushing direction of the pushing part 1101 is opposite to or has an angle with the moving direction of the clamping part 1103.

[0090] In one embodiment, the clamping mechanism 110 is arranged on the swing device 10, after the crystal holder 30 is installed to the bottom of the swing device 10, the clamping mechanism 110 works, the pushing part 1101 pushes the transmission part 1102, the transmission part 1102 drives the clamping part 1103 to move upward, the movement of the clamping part 1103 makes the crystal holder 30 move upward and be clamped on the bottom of the swing device 10. When disassembling the crystal holder 30, the clamping mechanism 110 reverses the action, the clamping part 1103 moves downward to release the crystal holder 30 from the bottom of the swing device 10, so that the crystal holder 30 is easily disassembled.

[0091] By arranging the pushing part 1101, the transmission part 1102, and the clamping part 1103 in the clamping mechanism 110, the spatial layout of the clamping mechanism 110 is flexible, improving its structural compactness and reducing production costs. Specifically, the pushing direction of the pushing part 1101 is opposite to or at an angle to the moving direction of the clamping part 1103. This allows the pushing part 1101 and the clamping part 1103 to be connected via the transmission part 1102, rather than being on the same straight line. This achieves the clamping action while reducing space occupation, improving the structural compactness of the clamping mechanism 110, and lowering production costs. Furthermore, since the pushing part 1101 and the clamping part 1103 are not directly connected, multiple pushing parts 1101 connected to the transmission part 1102 simultaneously can achieve better clamping or releasing effects.

[0092] It should be noted that although the clamping mechanism 110 is described in conjunction with the swing device 10 in this application, this is not intended to limit the scope of protection of this application. Those skilled in the art can also apply the clamping mechanism 110 to other application scenarios. For example, the clamping mechanism 110 can also be applied to a wire cutting machine without the swing device 10, and the clamping mechanism 110 is set on the feed assembly to clamp or release the crystal holder 30.

[0093] The following reference Figures 1 to 11 The preferred embodiments of the clamping mechanism 110 of this application will be described in conjunction with the swing device 10.

[0094] First refer to Figure 1 and Figure 2 In a preferred embodiment, the swing device 10 includes a first swing plate 101, a second swing plate 102, a first drive unit 103, a first drive gear 104, a second drive unit 105, a second drive gear 106, a driven gear 107, a guide mechanism 108, a clamping assembly 109, a clamping mechanism 110, and a detection assembly 113.

[0095] The first swing plate 101 and the second swing plate 102 are both rectangular plates, and the second swing plate 102 is located below the first swing plate 101. The first driving part 103 and the second driving part 105 are both arranged on the first swing plate 101, the first driving gear 104 is connected with the first driving part 103, the second driving gear 106 is connected with the second driving part 105, the driven gear part 107 is arranged on the second swing plate 102, and the first driving gear 104 and the second driving gear 106 are both connected with the driven gear part 107. The guide mechanism 108 is arranged between the first swing plate 101 and the second swing plate 102, and the guide mechanism 108 is partially connected with the first swing plate 101 and partially connected with the second swing plate 102. The clamping assembly 109 is arranged on the second swing plate 102 and is used for being connected with the crystal holder 30 to realize the load installation of the crystal holder 30. The clamping mechanism 110 is arranged on the second swing plate 102 and is used for further clamping the crystal holder 30 after the crystal holder 30 is installed on the clamping assembly 109 to realize the locking of the crystal holder 30. The detection assembly 113 is used for detecting the state of the clamping mechanism 110 and / or the swing angle of the swing device 10 to monitor the state of the swing device 10.

[0096] Referring to Figures 1 to 3 , the first driving part 103 is fixedly arranged on the upper side of the first swing plate 101. Specifically, the upper side of the first swing plate 101 is fixedly connected with a first support 111, and the first driving part 103 is fixedly connected with the first support 111. More specifically, the first driving part 103 includes a motor and a speed reducer, the output shaft of the motor is connected with the input shaft of the speed reducer, the speed reducer is fixedly connected with the first support 111, and the output shaft of the speed reducer extends out of the first support 111 and is connected with the first driving gear 104. Similarly, the second driving part 105 is fixedly arranged on the upper side of the first swing plate 101, the upper side of the first swing plate 101 is fixedly connected with a second support 112, and the second driving part 105 is fixedly connected with the second support 112. Specifically, the second driving part 105 also includes a motor and a speed reducer, the output shaft of the motor is connected with the input shaft of the speed reducer, the speed reducer is fixedly connected with the second support 112, and the output shaft of the speed reducer extends through the second support 112 and is connected with the second driving gear 106. The first swing plate 101 is provided with a second through hole 1011, and the first driving gear 104 and the second driving gear 106 are engaged with the driven gear in the second through hole 1011. In this application, the second through hole 1011 is arranged in the middle of the first swing plate 101 and extends along the width direction of the first swing plate 101 (see Figure 1 ), and the first driving part 103 and the second driving part 105 are centrally symmetrically arranged relative to the upper side of the first swing plate 101. The first driving gear 104 and the second driving gear 106 are completely the same in structure and are arranged side by side, and after being arranged, the sum of the widths of the first driving gear 104 and the second driving gear 106 is less than or equal to the width of the driven gear part 107.

[0097] By fixing the first driving part 103 and the second driving part 105 on the upper side of the first swing plate 101, the installation of the first driving part 103 is facilitated, and the structural complexity of the swing device 10 is reduced. By using the first support 111 and the second support 112 to respectively install the first driving part 103 and the second driving part 105, the installation stability of the first driving part 103 can be improved. By centrally and symmetrically arranging the first driving part 103 and the second driving part 105, the vibration during the operation of the swing device 10 can be reduced, and the operation stability of the swing device 10 can be improved. By arranging the first driving gear 104 and the second driving gear 106 side by side, the structure of the swing device 10 is compact, and the operation stability of the swing device 10 is improved. By arranging the first driving gear 104 and the second driving gear 106 with the same structure, the stability of the swing process and the transmission consistency can be improved. By arranging the first driving gear 104 and the second driving gear 106 with a width sum less than the width of the driven tooth part 107, the two driving gears can be in full contact with the driven tooth part 107, and the transmission efficiency can be improved.

[0098] Of course, the first driving part 103, the second driving part 105, the first driving gear 104 and the second driving gear 106 are only a preferred arrangement, and those skilled in the art can adjust the arrangement of the above features without departing from the principles of the application, so that the application is applicable to more specific application scenarios. For example, the first driving gear 104 and the second driving gear 106 can be arranged staggered with each other, as long as they can be engaged with the driven gear part 107 at the same time. For another example, the structures of the first driving gear 104 and the second driving gear 106 can also be different, as long as they can be engaged with the driven gear part 107, and those skilled in the art can adjust the structures of the first driving gear 104 and the second driving gear 106 arbitrarily. For another example, the sum of the widths of the first driving gear 104 and the second driving gear 106 can also be greater than the width of the driven gear part 107, and such a change does not deviate from the principles of the application. For another example, one or all of the first driving part 103 and the second driving part 105 can also be arranged on the lower side or the outer side of the first swing plate 101, as long as the first driving part 103 and the second driving part 105 can be effectively fixed. For another example, the first support 111 and the second support 112 are not necessary, and the first driving part 103 and / or the second driving part 105 can also be directly connected to the first swing plate 101. For another example, the central symmetry arrangement of the first driving part 103 and the second driving part 105 is only a preferred way, and they can also adopt other positional relationships, such as axial symmetry arrangement, asymmetric arrangement, etc. For another example, in addition to gear transmission, the transmission assembly can also be a gear belt assembly, the gears in the gear belt assembly are connected to the driving parts, the transmission belt in the gear belt assembly is engaged with the gears, and the two ends of the transmission belt are fixedly connected to the first swing plate 101. For another example, those skilled in the art can also set only one driving part to cooperate with one driving gear to drive the swing of the second swing plate 102, and such an adjustment does not deviate from the principles of the application.

[0099] Continuing to refer to Figures 1 to 3 In a preferred embodiment, the driven gear part 107 includes an integrally formed body 1071 and a tooth structure 1072, the body 1071 is a plate body, the lower part of the body 1071 is fixedly connected to the upper side of the second swing plate 102, the top of the body 1071 is arc-shaped, and the tooth structure 1072 is formed on the top of the body 1071. After being arranged, the tooth structure 1072 partially extends into the second through hole 1011 and is engaged with the first driving gear 104 and the second driving gear 106.

[0100] By integrally forming the body 1071 and the tooth structure 1072, the integrity of the driven gear part 107 can be improved, the transmission accuracy can be improved, and the failure rate can be reduced.

[0101] Of course, the specific arrangement of the driven gear portion 107 is not unique. In an alternative embodiment, the driven gear portion 107 includes a body 1071 and an arc-shaped rack, the lower part of the body 1071 is fixedly connected to the second swing plate 102, the top of the body 1071 is arc-shaped, and the arc-shaped rack is fixedly connected to the top of the body 1071 by screwing, pin connection or other means. In another alternative embodiment, the body 1071 can be omitted, i.e., the driven gear portion 107 only includes an arc-shaped rack, which is fixedly connected to the upper side of the second swing plate 102. At this time, the first driving gear 104 and the second driving gear can pass through the second through hole 1011 and engage with the arc-shaped rack.

[0102] With reference to Figure 1 and Figure 2 The guide mechanism 108 is connected between the first swing plate 101 and the second swing plate 102 for guiding when the second swing plate 102 swings. Specifically, the guide mechanism 108 includes an arc-shaped guide rail 1081 and an arc-shaped sliding groove 1082, one of the arc-shaped guide rail 1081 and the arc-shaped sliding groove 1082 is fixedly connected to the lower side of the first swing plate 101, and the other is fixedly connected to the upper side of the second swing plate 102. In this application, the arc-shaped sliding groove 1082 is fixedly connected to the lower side of the first swing plate 101, the arc-shaped guide rail 1081 is fixedly connected to the upper side of the second swing plate 102, and the arc-shaped guide rail 1081 is inserted into the arc-shaped sliding groove 1082. Preferably, two guide mechanisms 108 are provided, which are arranged on both sides of the driven gear portion 107 and are centrally symmetrically arranged relative to the upper side of the second swing plate 102.

[0103] By providing the guide mechanism 108, guidance can be provided during the swinging of the swinging device 10, improving the swinging accuracy and stability of the swinging device 10. By providing two guide mechanisms 108, the stability of the guidance can be improved. By centrally symmetrically arranging the two guide mechanisms 108, the swinging consistency of the swinging device 10 can be improved, thereby improving the working stability of the swinging device 10.

[0104] Of course, the arrangement of the guide mechanism 108 is not fixed, and those skilled in the art can adjust its arrangement. For example, in an alternative embodiment, the guide mechanism 108 includes an arc-shaped guide rail 1081 and a slider. One of the arc-shaped guide rail 1081 and the slider is fixedly connected to the lower side of the first swing plate 101, and the other is fixedly connected to the upper side of the second swing plate 102. Furthermore, the number of guide mechanisms 108 can be one, three, or more, and those skilled in the art can flexibly choose according to the size and layout space of the swing device 10. Moreover, when there are multiple guide mechanisms 108, the multiple guide mechanisms 108 can be arranged on both sides of the driven tooth portion 107, or simultaneously on the same side of the driven tooth portion 107. When multiple guide mechanisms 108 are arranged on both sides of the driven tooth portion 107, they can be centrally symmetrically arranged or asymmetrically arranged.

[0105] Continue to refer to Figures 1 to 3 The clamping assembly 109 is connected to the second swing plate 102 and is used to mate with the crystal tray 30. Specifically, the clamping assembly 109 includes a clamping plate 1091 and a clamping track 1092. The clamping plate 1091 is fixedly connected to the lower side of the second swing plate 102 by means of screwing, welding, riveting, etc. The clamping track 1092 is used to mate with the crystal tray 30 and is disposed at the bottom of the clamping plate 1091. In this application, there are two clamping tracks 1092, which are symmetrically arranged. After being set, the two clamping tracks 1092 and the clamping plate 1091 form an installation space, and the upper part of the crystal tray 30 can be inserted and locked in the installation space. The clamping assembly 109 also includes a limiting plate 1093 and a limiting rod (not shown in the figure). The limiting plate 1093 is disposed at one end of the lower side of the clamping plate 1091 and is used to limit the crystal tray 30 in the length direction during the installation of the crystal tray 30. The limiting rod is disposed on one side of the lower side of the clamping plate 1091 and extends along the length direction of the clamping plate 1091. Correspondingly, a limiting groove is formed on the top surface of the crystal tray 30. During the installation of the crystal tray 30, the limiting groove on the top surface of the crystal tray 30 slides and engages with the limiting rod, thereby limiting the crystal tray 30 in the width direction.

[0106] By setting the limiting plate 1093, the positioning accuracy of the crystal tray 30 can be improved, thereby improving the cutting accuracy. By setting the limiting rod, the positioning accuracy of the crystal tray 30 can be improved, enabling the clamping assembly 109 to have a foolproof function.

[0107] Of course, the specific arrangement of the clamping assembly 109 is not unique, and those skilled in the art can adjust the arrangement of the clamping assembly 109 without departing from the principles of the present application. For example, the clamping assembly 109 can not include the clamping plate 1091, but the clamping rail 1092 is directly fixedly connected to the second swing plate 102. For another example, the setting of the limiting plate 1093 and the limiting rod is not necessary, and those skilled in the art can choose whether to retain according to the actual application scene.

[0108] Next, referring to Figures 4 to 11 , the clamping mechanism 110 will be described in detail.

[0109] As shown in Figure 1 and Figure 4 , the clamping mechanism 110 is arranged on the second swing plate 102, and the clamping mechanism 110 is used to clamp the wafer carrier 30. Specifically, two clamping mechanisms 110 are arranged, and the two clamping mechanisms 110 are arranged on both sides of the driven tooth part 107 and are centrally symmetrically arranged relative to the upper side of the second swing plate 102. Each clamping mechanism 110 includes a pushing part 1101, a transmission part 1102, a clamping part 1103, a base 1104, and a limiting assembly 1105, the base 1104 is arranged on the upper side of the second swing plate 102 and connected with the second swing plate 102, and the pushing part 1101, the transmission part 1102, the clamping part 1103 and the limiting assembly 1105 are all arranged on the base 1104. The pushing part 1101 is connected with the transmission part 1102, the transmission part 1102 is connected with the clamping part 1103, the pushing part 1101 can push the transmission part 1102 to act, so that the transmission part 1102 drives the clamping part 1103 to move in a straight line direction, so as to clamp or release the wafer carrier 30, and the pushing direction of the pushing part 1101 and the moving direction of the clamping part 1103 have an included angle, in the present application, the pushing direction of the pushing part 1101 is horizontal direction, and the moving direction of the clamping part 1103 is vertical direction, that is, the included angle between them is right angle. The transmission part 1102 can convert the horizontal thrust of the pushing part 1101 into vertical thrust to push the clamping part 1103 to move.

[0110] Specifically, referring to Figure 4 , Figure 5 and Figure 7The pushing part 1101 comprises a piston 11011, a push rod 11012 and a sealing ring 11013. The piston 11011 is movably arranged in the base 1104, the first end of the piston 11011 is connected with the power source, and the second end is connected with the transmission part 1102. Specifically, the first side surface of the base 1104 is provided with a mounting hole 11041, and the piston 11011 is movably arranged in the mounting hole 11041. The bottom of the mounting hole 11041 is closed, the outer circumferential side of the piston 11011 is sleeved with the sealing ring 11013, and the piston 11011 is sealingly and slidably installed in the mounting hole 11041 through the sealing ring 11013. The base 1104 is also provided with a first through hole 11042 in communication with the closed end of the mounting hole 11041, and the closed end of the mounting hole 11041 communicates with the power source through the first through hole 11042. Preferably, the power source is an air pump, which communicates with the first through hole 11042 through an air pipe. When the air pump is started and operated, the piston 11011 is pushed and slides along the mounting hole 11041 under the action of air pressure. The two ends of the push rod 11012 are respectively connected with the transmission part 1102 and the piston 11011. Specifically, the piston 11011 is provided with a first counterbore 11014, and the transmission part 1102 is provided with a second counterbore 11024. The two ends of the push rod 11012 abut against the hole bottoms of the first counterbore 11014 and the second counterbore 11024 respectively. When the piston 11011 is pushed, the piston 11011 drives the push rod 11012 to move, and the push rod 11012 pushes the transmission part 1102 to act. Preferably, two pushing parts 1101 are provided, and the two pushing parts 1101 are arranged side by side on the same side surface of the base 1104, and the pistons 11011 of the two pushing parts 1101 are connected with the transmission part 1102 at the same time.

[0111] The pushing part 1101, the transmission part 1102 and the clamping part 1103 are arranged by the clamping mechanism 110, which is beneficial to the flexible layout of the space of the clamping mechanism 110, improves the compactness of the structure of the clamping mechanism 110, and reduces the production cost. Specifically, the pushing part 1101 and the clamping part 1103 can not be arranged on the same straight line by the setting mode that the pushing direction of the pushing part 1101 and the moving direction of the clamping part 1103 have an included angle, but are driven and connected by the transmission part 1102, so as to realize the clamping action, reduce the occupation of space, improve the compactness of the structure of the clamping mechanism 110, and reduce the production cost. By arranging two pushing parts 1101, the transmission part 1102 can be pushed by the two pushing parts 1101 at the same time to achieve better clamping or loosening effect, while reducing the overall space occupation of the pushing part 1101.

[0112] By setting the pushing part 1101, the transmission part 1102 and the clamping part 1103 on the base 1104 at the same time, it is beneficial to realize the effective fixation of the above-mentioned parts, and it is beneficial to the clamping mechanism 110 to form a product independently and to be installed as a whole. By setting the piston 11011, the movement of the piston 11011 relative to the base 1104 can be used to push the transmission part 1102, realizing the movement of the clamping part 1103. By setting two clamping mechanisms 110, the clamping effect on the crystal holder 30 can be improved. By setting the two clamping mechanisms 110 centrally symmetrically, the clamping consistency of the swing device 10 can be improved, thereby improving the working stability of the swing device 10. By movably setting the piston 11011 in the mounting hole 11041, the installation and action of the piston 11011 can be realized at the same time. By directly sealingly slidingly installing the piston 11011 in the mounting hole 11041, the mounting hole 11041 can be used as the cavity of the piston 11011, which can greatly reduce the structural complexity of the clamping mechanism 110. By setting the power source as a gas source or a hydraulic pump, the effective movement of the piston 11011 can be realized by using gas pressure. By setting the push rod 11012, it is beneficial to realize the power transmission between the piston 11011 and the transmission part 1102. By abutting the two ends of the push rod 11012 at the hole bottom of the first counterbore 11014 and the hole bottom of the second counterbore 11024, the structural compactness of the clamping mechanism 110 can be improved, and the volume of the clamping mechanism 110 can be reduced.

[0113] Referring to Figure 4 , Figure 5 and Figure 8 , the transmission part 1102 includes a connecting rod, the connecting rod is pivotally arranged on the base 1104, the first end of the connecting rod is connected with the second end of the piston 11011, and the second end of the connecting rod is connected with the clamping part 1103. Specifically, the connecting rod includes a first rod segment 11021, a second rod segment 11022 and a third rod segment 11023 connected in sequence, the first end of the first rod segment 11021 is connected with the third rod segment 11023, the second end of the first rod segment 11021 is connected with the first end of the second rod segment 11022, and the second end of the second rod segment 11022 is connected with the clamping part 1103. The two pushing parts 1101 are located on both sides of the first rod segment 11021, the third rod segment 11023 is arranged in the direction of the connecting line of the two pushing parts 1101, and the third rod segment 11023 is formed by the first end of the first rod segment 11021 extending to both sides of the first rod segment 11021. Each third rod segment 11023 is provided with a second counterbore 11024 at an end away from the first rod segment 11021, and the second counterbore 11024 is connected with one end of the push rod 11012.

[0114] The connecting position of the first rod segment 11021 and the second rod segment 11022 is provided with a first pivoting structure, the base 1104 is provided with a second pivoting structure, and the first pivoting structure is pivotally connected with the second pivoting structure. Specifically, a groove 11043 is arranged in the middle of the top surface of the base 1104, the two side walls of the groove 11043 extend outward to form two lugs 11044, and the lugs 11044 are provided with the second pivoting structure. Preferably, the first pivoting structure is a first pivoting hole, the second pivoting structure is a second pivoting hole, and the first pivoting hole and the second pivoting hole are connected through a pivoting shaft. When the piston 11011 pushes the third rod segment 11023, the connecting rod pivots around the pivoting shaft, the first rod segment 11021 and the third rod segment 11023 pivot upward, and the second rod segment 11022 is driven to pivot downward.

[0115] The second end of the second rod segment 11022 is also provided with a pressing piece 11025, and the connecting rod is connected with the clamping part 1103 through the pressing piece 11025. Specifically, the pressing piece 11025 is a roller, the roller is provided with a first connecting structure, the second end of the connecting rod is provided with a mounting position, the mounting position is provided with a second connecting structure, the first connecting structure is connected with the second connecting structure, and the roller is rotatably connected to the second end of the connecting rod. Preferably, the mounting position is a through groove, the first connecting structure is a first shaft hole, the second connecting structure is a second shaft hole, and the first shaft hole and the second shaft hole are connected through a rotating shaft, so that the roller is rotatably embedded in the through groove.

[0116] The transmission part 1102 is arranged as a connecting rod, the power transmission can be realized by pivoting of the connecting rod, so as to realize the movement of the clamping part 1103. By arranging the first rod segment 11021 and the second rod segment 11022, the compactness of the clamping mechanism 110 is improved. By arranging the pressing piece 11025 at the second end of the connecting rod, the pressing piece 11025 can be used to press the clamping part 1103, and the working stability of the clamping mechanism 110 is improved. By arranging the pressing piece 11025 as a roller, the friction between the pressing piece 11025 and the clamping part 1103 during pressing can be reduced, and the stability of the pressing process is improved. By arranging the third rod segment 11023, the connection stability of the two pushing parts 1101 and the connecting rod is improved. By arranging the pushing part 1101 on both sides of the first rod segment 11021, the stress of the connecting rod during pushing is uniform, and the working stability of the clamping device is improved.

[0117] Referring to Figure 4 and Figure 8The limiting assembly 1105 is arranged on the base 1104 and is used to limit the pivoting angle of the connecting rod. Specifically, the limiting assembly 1105 includes a limiting block 11051 and a through fastener 11052. The limiting block 11051 is fixedly connected to the base 1104, and a threaded hole is formed in the limiting block 11051. The through fastener 11052 is screwed into the threaded hole and is arranged opposite to the first end of the first rod segment 11021. In this application, the through fastener 11052 is a hexagonal plug, which is screwed into the threaded hole in the limiting block 11051. After installation, the limiting block 11051 has a certain distance from the base 1104, and the part of the first end of the first rod segment 11021 that extends downward relative to the third rod segment 11023 can move in the space. By adjusting the length of the hexagonal plug extending into the threaded hole, the movement distance of the first rod segment 11021 during pivoting can be adjusted.

[0118] By arranging the limiting assembly 1105, the pivoting angle of the connecting rod can be limited by the limiting assembly 1105 to control the degree to which the connecting rod presses downward against the clamping part 1103, thereby achieving adjustment of the clamping force.

[0119] Referring to Figure 4 , Figure 6 , Figure 8 and Figure 9 , the clamping part 1103 includes a clamping cylinder base 11031, a clamping cylinder rod 11032, an elastic member 11033, a positioning member 11034, a guide sleeve 11035, and a nut 11036. Specifically, the clamping cylinder base 11031 is fixedly connected to the base 1104. More specifically, the second swing plate 102 is provided with a through hole at a position corresponding to the clamping part 1103, and the clamping cylinder base 11031, the base 1104, and the clamping plate 1091 are connected together by fasteners. As shown in Figure 9 , a countersunk hole is formed in the clamping plate 1091, a through hole is formed in the bottom of the clamping cylinder base 11031, and a threaded hole is formed in the bottom of the base 1104. A hexagonal bolt passes through the clamping plate 1091 and the clamping cylinder base 11031 and is screwed into the threaded hole in the bottom of the base 1104, thereby achieving fixed connection of the clamping cylinder base 11031, the base 1104, and the clamping plate 1091.

[0120] The first end of the clamping cylinder rod 11032 is provided with a clamping structure, the second end of the clamping cylinder rod 11032 is connected with the transmission part 1102, the clamping cylinder rod 11032 is slidably arranged in the clamping cylinder seat 11031, and the clamping structure extends out of the clamping cylinder seat 11031. Specifically, the clamping structure is a reverse T-shaped rod, a sliding hole 11045 is formed in the base 1104, the clamping cylinder seat 11031 is fixedly connected to one end of the sliding hole 11045, and the second end of the clamping cylinder rod 11032 extends into the sliding hole 11045. The positioning piece 11034 is fixedly connected to the clamping cylinder rod 11032, and the two ends of the elastic piece 11033 abut against the positioning piece 11034 and the clamping cylinder seat 11031 respectively. When the transmission part 1102 drives the clamping part 1103 to move in a straight line direction, the elastic piece 11033 stores elastic potential energy. Preferably, the second end of the clamping cylinder rod 11032 is provided with a shaft shoulder, the positioning piece 11034 is a gasket, the gasket abuts against the shaft shoulder and is locked on the clamping cylinder rod 11032 by being screwed to the second end of the clamping cylinder rod 11032 through the nut 11036. Preferably, the elastic piece 11033 is a disc spring, and a plurality of disc springs are sleeved on the clamping cylinder rod 11032, and after being sleeved, the disc springs are located between the positioning piece 11034 and the clamping cylinder seat 11031.

[0121] The guide sleeve 11035 is fixedly sleeved on the second end of the clamping cylinder rod 11032, and the outer wall of the guide sleeve 11035 matches the inner wall of the sliding hole 11045. Preferably, the guide sleeve 11035 is penetrated on the second end of the clamping cylinder rod 11032 and covers part of the nut 11036, and after being penetrated, the second end of the clamping cylinder rod 11032 clamps the guide sleeve 11035 by using an elastic snap ring. Referring to Figure 8 In the set case, the bottom of the roller abuts against the top end of the clamping cylinder rod 11032.

[0122] By arranging the elastic piece 11033, the elastic piece 11033 can be used to realize the automatic return of the clamping part 1103. Especially when the pushing part 1101 is used to exit the clamping cylinder rod 11032, the elastic potential energy of the elastic piece 11033 can be used to realize the automatic return of the clamping part 1103 to clamp the wafer holder 30, without the need to additionally introduce a power mechanism to clamp the wafer holder 30, and the setting mode is simple and practical. By fixing the clamping cylinder seat 11031 at one end of the sliding hole 11045, the fixation of the clamping part 1103 is facilitated. By arranging the guide sleeve 11035, the clamping cylinder rod 11032 can be guided, and the movement stability of the clamping cylinder rod 11032 is improved.

[0123] The action principle of the clamping mechanism 110 will be briefly introduced below. Figure 4 , Figure 8 , Figure 10 and Figure 11 .

[0124] When the crystal holder 30 needs to be installed, the air pump is controlled to start running, and the air pressure enters the installation hole 11041 through the first through hole 11042 and pushes the piston 11011 to move outward. The piston 11011 pushes the third rod segment 11023 through the push rod 11012, and then the third rod segment 11023 is pivoted upward, and the second rod segment 11022 is pivoted downward. In the process of the second rod segment 11022 being pivoted downward, the roller presses downward on the top of the clamping cylinder rod 11032, the clamping cylinder rod 11032 moves downward under the guidance of the guide sleeve 11035, the inverted T-shaped rod moves downward, and the disc spring is compressed to be elastically deformed. At this time, the crystal holder 30 can be slidably clamped to the clamping plate 1091 through the cooperation of the inverted T-shaped groove on the crystal holder 30 and the inverted T-shaped rod, and with the guidance of the clamping rail 1092 and the limiting rod. After the crystal holder 30 is installed in place, the controller pump stops running, the disc spring releases the elastic potential energy to drive the clamping cylinder rod 11032 to move upward, the inverted T-shaped rod drives the crystal holder 30 to move upward together, and finally the crystal holder 30 is clamped to the bottom surface of the clamping plate 1091.

[0125] Of course, the above-mentioned clamping mechanism 110 is only a preferred technical solution, and those skilled in the art can understand that the implementation of the clamping mechanism 110 is not unique, and as long as the mechanism can effectively clamp the crystal holder 30, the above-mentioned clamping mechanism 110 can be replaced.

[0126] For example, although the above-mentioned clamping mechanism 110 is introduced in combination with the pushing part 1101, the transmission part 1102, the clamping part 1103, the base 1104 and the limiting assembly 1105, the structure of the clamping mechanism 110 is not limited to this, and those skilled in the art can replace it, as long as the replaced clamping mechanism 110 can clamp the crystal holder 30. For example, the clamping mechanism 110 only includes the pushing part 1101 and the clamping part 1103, and more specifically, the clamping mechanism 110 is a pneumatic cylinder or a hydraulic cylinder. For another example, the clamping mechanism 110 can only include the pushing part 1101, the transmission part 1102 and the clamping part 1103, and each of them is fixed on the first swing plate 101 or the second swing plate 102, so that the setting of the base 1104 is omitted. For another example, the number of clamping mechanisms 110 is not unique, and one, three or more clamping mechanisms 110 can also be provided.

[0127] For example, the pushing part 1101 is introduced in combination with the piston 11011, the pushing rod 11012 and the sealing ring 11013, but the structure and arrangement mode are not unique. For example, the pushing part 1101 can also include a cylinder and a piston 11011, and the cylinder is fixedly embedded in the mounting hole 11041. For example, the pushing rod 11012 can also be omitted. For example, one or all of the first counterbore 11014 and the second counterbore 11024 can be omitted. For example, although the above-mentioned power source is described in combination with the air pump, the power source is not limited, and those skilled in the art can also replace it, such as replacing it with a hydraulic pump. For example, although the pushing part 1101 is introduced in combination with two, the number is not unique, and the number can also be one, three or more.

[0128] For example, the structure of the connecting rod is not unique, and it can only include the first rod segment 11021 or only include the first rod segment 11021 and the second rod segment 11022. The first pivot structure can be arranged on the first rod segment 11021 and the second rod segment 11022 in addition to the connecting part. In addition, the first pivot structure and the second pivot structure are not unique. For example, the first pivot structure can also be a pivot hole, and the second pivot structure is a pivot shaft. The pivot hole is sleeved on the pivot shaft. Or the first pivot structure is a pivot shaft, and the second pivot structure is a pivot hole. The pivot shaft is inserted into the pivot hole. For example, the pushing direction of the pushing part 1101 and the moving direction of the clamping part 1103 are not only perpendicular, but also any angle, or the moving directions of the two are opposite. For example, the connecting rod is arranged horizontally, the pushing part 1101 pushes one end of the connecting rod upward, and the other end of the connecting rod is pivoted downward and presses the clamping part 1103. For example, although the second end of the second rod segment 11022 is provided with the pressing part 11025, the pressing part 11025 is not necessary, and the structure is not limited to a roller. For example, the pressing part 11025 can also be a pressing block, a ball, etc. For example, the forms of the first connecting structure and the second connecting structure are not unique, and they can be adjusted. For example, the first connecting structure is a shaft hole, and the second connecting structure is a pivot shaft. The shaft hole is sleeved on the pivot shaft. Or the first connecting structure is a pivot shaft, and the second connecting structure is a shaft hole. The pivot shaft is inserted into the shaft hole. For example, the mounting position can also be a protruding structure or a stepped surface in addition to the through groove.

[0129] For example, the limiting assembly 1105 can not be arranged, or the arrangement mode can be adjusted. For example, the arrangement position of the limiting block 11051 can be adjusted, and the through fastener 11052 can also be a bolt in addition to the internal hexagonal plug.

[0130] For example, the clamping portion 1103 is not the only way to set, as long as it can meet the effective connection with the crystal holder 30, the skilled in the art can adjust its setting. For example, the clamping mechanism 110 can be a trapezoidal rod instead of the inverted T-shaped rod. For example, as long as the clamping portion 1103 includes the clamping cylinder rod 11032, other components can be selectively omitted. For example, the clamping portion 1103 can only include the clamping cylinder rod 11032, and the clamping cylinder rod 11032 can be in transmission connection with the second end of the connecting rod, so that the pivoting movement of the connecting rod can drive the clamping cylinder rod 11032 to rise and fall, and when it rises, it clamps the crystal holder 30, and when it falls, it loosens the crystal holder 30. For example, the elastic member 11033 can be a compression spring in addition to a plurality of disc springs, and the two ends of the compression spring are respectively in abutment with the positioning member 11034 and the clamping cylinder seat 11031. In addition to being fixed together with the base 1104 and the clamping plate 1091, the clamping cylinder seat 11031 can also be fixed separately with the base 1104. For example, in an alternative embodiment, the guide sleeve 11035 can also be combined with the nut 11036.

[0131] Referring to Figure 2 and Figure 3 , the detection assembly 113 is arranged on the second swing plate 102, and is used to detect the swing angle of the swing device 10 and / or the state of the clamping mechanism 110. Specifically, the detection assembly 113 includes a position sensor 1131 and an angle sensor 1132, the position sensor 1131 is arranged on the second swing plate 102 and is used to detect the state of the clamping mechanism 110, and the angle sensor 1132 is arranged on the second swing plate 102 and is used to detect the swing angle of the swing device 10.

[0132] The position sensor 1131 detects the state of the clamping mechanism 110 by detecting the position of the transmission part 1102. Preferably, the position sensor 1131 is arranged on the upper side of the second swing plate 102 and at one end of the second swing plate 102 along the length direction thereof, the third rod segment 11023 of the clamping mechanism 110 is directed outward, and the position sensor 1131 is arranged corresponding to the end of the third rod segment 11023. The upper side of the second swing plate 102 is provided with a first mounting bracket 114, and the position sensor 1131 is fixed to the first mounting bracket 114. The first mounting bracket 114 is an L-shaped plate, the horizontal plate of the L-shaped plate is fixed to the upper side of the second swing plate 102 by means of bolts, welding or riveting, and the position sensor 1131 is fixed to the vertical plate of the L-shaped plate by means of screwing, clamping or the like. In this application, the detection assembly 113 includes two position sensors 1131, which are arranged at both ends of the second swing plate 102 along the length direction thereof, and each position sensor 1131 is arranged corresponding to the end of a third rod segment 11023. Preferably, the position sensor 1131 is a proximity sensor, and when the third rod segment 11023 is pivoted upward under the push of the piston 11011, the third rod segment 11023 approaches the position sensor 1131, so as to be detected by the position sensor 1131.

[0133] By arranging the detection assembly 113, the swing angle of the swing device 10 and the state of the clamping mechanism 110 can be detected, the safety of the swing device 10 is improved, and the safety risk in the working process of the swing device 10 is reduced. By arranging the position sensor 1131, the state of the clamping mechanism 110 can be detected, the safety of the swing device 10 is improved, and the safety risk is reduced. By detecting the position of the transmission part 1102 through the position sensor 1131, the state of the clamping mechanism 110 can be detected, and the detection difficulty is reduced. By arranging the position sensor 1131 corresponding to the pivot end, the position sensor 1131 can be used to detect the state of the clamping mechanism 110 by taking advantage of the large position change amplitude of the connecting rod during pivoting, and the detection accuracy is improved. By arranging the position sensor 1131 on the upper side of the second swing plate 102, the installation is facilitated, and interference with the components connected to the lower side of the second swing plate 102 is avoided. By arranging the position sensor 1131 at one end of the second swing plate 102 along the length direction thereof, the installation and maintenance of the position sensor 1131 are facilitated. By using the first mounting bracket 114 to fix the position sensor 1131, the position sensor 1131 can be simply installed, and the installation position of the position sensor 1131 can be adjusted to make the position sensor 1131 applicable to more different types of swing devices 10. By arranging one position sensor 1131 corresponding to each of the two clamping mechanisms 110, the two clamping mechanisms 110 can be detected simultaneously, the detection accuracy is improved, and the safety risk is further reduced.

[0134] Continuing to refer to Figure 2and Figure 3 The angle sensor 1132 is arranged on the upper side of the second swing plate 102 and at the middle of one end of the second swing plate 102 along the length direction thereof. The second swing plate 102 is provided with a second mounting bracket 115 at the middle of the end, and the angle sensor 1132 is fixed to the second mounting bracket 115. Preferably, the mounting bracket is a H-shaped plate, two lower horizontal plates of the H-shaped plate are fixedly connected to the top surface of the second swing plate 102 by screwing, welding or riveting, and the angle sensor 1132 is fixed to the upper horizontal plate of the H-shaped plate by screwing, riveting or the like. The specific form of the angle sensor 1132 is not limited, and any sensor capable of detecting the swing angle can be applied to the present application. During the swing of the second swing plate 102 relative to the first swing plate 101, the angle sensor 1132 can detect the swing angle of the second swing plate 102, so that the wire cutting machine can judge the swing condition of the second swing plate 102 based on the angle.

[0135] By arranging the angle sensor 1132 to detect the swing angle of the swing device 10, the swing of the swing device 10 can be judged by the detection of the swing angle whether it is within the preset range, so as to avoid the swing exceeding the preset range to cause safety accidents, improve the safety of the swing device 10, and reduce the safety risk. By arranging the angle sensor 1132 on the upper side of the second swing plate 102, the installation is facilitated, and interference with the components connected to the lower side of the second swing plate 102 is avoided. By arranging the angle sensor 1132 at one end of the second swing plate 102 along the length direction thereof, the installation and maintenance of the angle sensor 1132 are facilitated. By using the second mounting bracket 115 to install the angle sensor 1132, it is beneficial to realize the simple installation of the angle sensor 1132, and it is beneficial to adjust the installation position of the angle sensor 1132, so that the angle sensor 1132 is suitable for more different models of swing devices 10.

[0136] Of course, the specific arrangement of the above-mentioned detection assembly 113 is not fixed, and those skilled in the art can adjust it so that the adjusted technical solution is suitable for more specific application scenarios.

[0137] For example, although the detection assembly 113 is introduced in combination with the position sensor 1131 and the angle sensor 1132, the detection assembly 113 can only include one of the two. For another example, although the position sensor 1131 is introduced in combination with being arranged corresponding to one end of the third rod segment 11023, the specific arrangement position is not fixed, and it can also be arranged at other positions as long as the action of the connecting rod can be detected. For example, the position sensor 1131 can also be arranged at the lower side of the first swing plate 101 and corresponding to the second rod segment 11022 to detect the pivoting of the second rod segment 11022. For another example, the position sensor 1131 can also be arranged corresponding to the middle part of the first rod segment 11021 or the third rod segment 11023. For another example, although the position sensor 1131 is introduced in combination with the proximity sensor, the specific form can be replaced, such as an infrared sensor, a laser sensor, etc. For another example, in addition to being fixed by the L-shaped bracket, the position sensor 1131 can also be fixed and connected by other shaped mounting racks. For another example, the number of the position sensor 1131 is not limited, and it can also be one, three or more, and the number does not have to correspond to the number of the clamping assembly.

[0138] For another example, the arrangement position of the angle sensor 1132 is not unique, and it can be fixed on the second swing plate 102 or the component connected with the second swing plate 102 as long as the pivoting angle of the second swing plate 102 can be detected. For another example, the specific form of the second mounting rack 115 is not unique, and those skilled in the art can adjust the structure as long as the angle sensor 1132 can be effectively fixed.

[0139] Of course, in other embodiments, the detection assembly 113 can also be omitted as a whole.

[0140] Of course, the replaceable embodiments and the preferred embodiments can also be cross-used, so as to combine new embodiments to be applied to more specific application scenarios.

[0141] The feeding assembly of the present application will be described below with reference to Figure 12 and Figure 13 The feeding assembly of the present application will be described below with reference to

[0142] As Figure 12 and 13 shown, the present application also provides a feeding assembly, which comprises a slide plate box 20 and the swing device 10 described above, and the swing device 10 is arranged on the slide plate box 20. Specifically, the bottom of the slide plate box 20 is formed with a containing cavity, and the first swing plate 101 is connected to the bottom of the slide plate box 20 and the first driving part 103 and the second driving part 105 are located in the containing cavity.

[0143] By setting the clamping mechanism 110 or the swing device 10 on the feeding assembly, the volume of the feeding assembly can be reduced, the structural compactness of the feeding assembly can be improved, and the production cost can be reduced. By forming the accommodating cavity at the bottom of the slide plate box 20 and accommodating the first driving part 103 and the second driving part 105 in the accommodating cavity, the volume of the feeding assembly can be reduced, the structural compactness of the feeding assembly can be realized, and the production cost can be reduced.

[0144] Of course, the setting mode of the feeding assembly is not limited to this, and those skilled in the art can adjust it. For example, the bottom of the slide plate box 20 can not form the accommodating cavity, and the first swing plate 101 can be directly connected to the bottom of the slide plate box 20.

[0145] In addition, the application also provides a wire cutting machine, which comprises the clamping mechanism 110, the swing device 10 or the feeding assembly.

[0146] By setting the clamping mechanism 110, the swing device 10 or the feeding assembly on the wire cutting machine, the structural compactness of the wire cutting machine can be improved, and the production cost of the whole machine can be reduced.
