[0064] See also Figure 1 , Figure 1 A processing device 100 provided in an embodiment of the present application is shown.

[0065] In an embodiment of the present application, the processing equipment 100 can perform coating processing on sheet materials. The processing equipment 100 may include a coating device 101 and a transfer device 102. The transfer device 102 can grab a material box 200 ( Figure 3 ), and moves the material box 200 to the coating device 101. The transfer device 102 can also grab the material box 200 equipped with multiple sheet materials from the coating device 101, and move the material box 200 out of the coating device 101. The coating device 101 can coat the multiple sheet materials in the material box 200 entering the coating device 101.

[0066] In the embodiments of the present application, the type of the sheet material is not specifically limited. For example, the sheet material may be a silicon sheet, a silicon carbide sheet, or a wafer.

[0067] It is understood that the coating device 101 can use the common principles in the relevant field to achieve coating of the sheet material. In the embodiment of the present application, there is no specific limitation on the type of process performed by the coating device 101. For example, the coating device 101 can perform a passivation process to achieve coating of the sheet material.

[0068] It can be understood that, according to the processing requirements for sheet materials, the processing equipment 100 may also include other devices in addition to the coating device 101 and the transfer device 102. The coating device 101 includes a process furnace for the process, and also includes other structures for receiving the material box 200 from the transfer device 102 and transporting the material box 200 to the process furnace. The embodiments of the present application are not limited to this.

[0069] Please also read Figure 2 , Figure 2A transfer device 102 provided in an embodiment of the present application is shown.

[0070] In an embodiment of the present application, the transfer device 102 may include a moving mechanism 1021 and a clamping mechanism 1022. The clamping mechanism 1022 may clamp and fix the material box 200. The clamping mechanism 1022 may be detachably connected to the moving mechanism 1021. The moving mechanism 1021 may drive the clamping mechanism 1022 to rotate and move linearly in multiple directions, thereby driving the material box 200 equipped with multiple sheet materials to move into or out of the coating device 101.

[0071] In the embodiments of the present application, there is no specific limitation on the type of the moving mechanism 1021. Figure 2 As shown, the moving mechanism 1021 may be a multi-axis robot. For another example, the moving mechanism 1021 may be a mechanism formed by assembling a plurality of linear motors and rotary motors, each of which may drive the clamping mechanism 1022 to move in a linear direction, and the rotary motor may drive the clamping mechanism 1022 to rotate.

[0072] In the embodiments of the present application, the detachable connection method is not specifically limited. For example, the detachable connection method may include, but is not limited to, bolt connection, snap connection, etc.

[0073] Please also read Figure 3 In the embodiment of the present application, an opening is provided on one side of the material box 200 in the width direction, and the opening is connected to the space inside the material box 200. A cover plate 201 can be placed at the opening of the material box 200. The sheet material can enter or move out of the material box 200 through the opening; when the sheet material is installed in the material box 200, the cover plate 201 can cover the opening to block the sheet material and prevent the sheet material from moving out of the material box 200 during the movement of the material box 200. In the cross-section passivation process, the cover plate 201 can prevent gas from entering the material box 200 from the opening, thereby preventing other surfaces of the sheet material from participating in unnecessary passivation processes.

[0074] A positioning hole 202 and a groove 203 are also provided on one side of the height direction of the material box 200. The positioning holes 202 can be provided in two rows, and the two rows of positioning holes 202 can be arranged at intervals in the length direction of the material box 200, and the number of positioning holes 202 in each row is at least one. The positioning holes 202 are all blind holes. The number of grooves 203 is two, and the two grooves 203 are arranged at intervals in the length direction of the material box 200.

[0075] Exemplarily, the positioning holes 202 and the grooves 203 may both be located at the bottom of the material box 200. The bottom of the material box 200 may be fixedly connected with two convex strips 204. The two convex strips 204 are arranged at intervals in the length direction of the material box 200 and extend in the width direction of the material box 200. Two rows of positioning holes 202 are respectively provided on the two convex strips 204. Each groove 203 is partially provided at the bottom of the material box 200 and partially extends into the corresponding convex strip 204 along the length direction of the material box 200.

[0076] In one embodiment, the clamping mechanism 1022 may include a base 10. The base 10 may be detachably connected to the moving mechanism 1021. The height direction of the base 10 may be defined as a vertical direction, the length direction as a first horizontal direction, and the width direction as a second horizontal direction. Figure 3 and Figure 4 As shown, the vertical direction may be the X direction and its opposite direction, the first horizontal direction may be the Y direction and its opposite direction, and the second horizontal direction may be the Z direction and its opposite direction. The vertical direction, the first horizontal direction, and the second horizontal direction are perpendicular to each other. When the clamping mechanism 1022 clamps the material box 200, the height direction of the material box 200 coincides with the vertical direction, the length direction coincides with the first horizontal direction, and the width direction coincides with the second horizontal direction.

[0077] The clamping mechanism 1022 may further include a positioning assembly 20, a tensioning assembly 30, and a stop assembly 40. The positioning assembly 20 and the tensioning assembly 30 may receive the material box 200 from the bottom. Both sides of the tensioning assembly 30 in the first horizontal direction may abut against the material box 200 to limit the movement of the material box 200. The stop assembly 40 may abut against the opening of the material box 200, thereby limiting the movement of the sheet material in the material box 200.

[0078] It can be understood that in some cases, the material box 200 is covered with a cover plate 201, the cover plate 201 blocks the opening of the material box 200, and the stop assembly 40 can stop against the cover plate 201 to limit the movement of the cover plate 201. In other cases, the material box 200 is not covered with a cover plate 201, and the stop assembly 40 can stop against the sheet material installed in the material box 200 to limit the movement of the sheet material.

[0079] Please also read Figure 5 and Figure 6In some embodiments, the positioning assembly 20 may include a positioning seat 21, an elastic member (not shown) and a positioning column 22. The positioning seat 21 is fixedly connected to the base 10. The positioning seat 21 may be arranged in two rows at intervals in the first horizontal direction, and the number of positioning seats 21 in each row is at least one. A positioning groove 211 is provided on the side of each positioning seat 21 away from the base 10. The number of elastic members and positioning columns 22 may be the same as the number of positioning seats 21, and a plurality of positioning seats 21, a plurality of positioning grooves 211, a plurality of elastic members and a plurality of positioning columns 22 may correspond to each other. An elastic member is accommodated in each positioning groove 211, and the elastic member may be fixedly connected to the bottom wall of the corresponding positioning groove 211. Part of the structure of each positioning column 22 is accommodated in the corresponding positioning groove 211, and each positioning column 22 is fixedly connected to the corresponding elastic member. Each positioning column 22 may be slidably connected to the corresponding positioning groove 211 in the vertical direction. The elastic member may support the corresponding positioning column 22.

[0080] When the positioning post 22 is pressed, the positioning post 22 can move into the positioning slot 211 and press the elastic member to cause the elastic member to deform elastically. When the pressure on the positioning post 22 is released, the elastic member can drive the positioning post 22 to move out of the positioning slot 211 through the elastic force generated by the elastic deformation.

[0081] In the embodiments of the present application, the fixing method of the fixed connection and the fixed installation is not specifically limited. For example, the fixing method may include, but is not limited to, bolt fixing, screw fixing, welding fixing, adhesive fixing, integral molding fixing, etc.

[0082] In the embodiments of the present application, the type of the elastic member is not specifically limited. For example, the elastic member may be, but is not limited to, a spring, a rubber block, etc.

[0083] It can be understood that each positioning seat 21 can abut against the bottom of the material box 200, so as to achieve the acceptance of the material box 200. Each positioning column 22 can enter the corresponding positioning hole 202, and can abut against the inner wall of the positioning hole 202 in the vertical direction. The inner side wall of the positioning hole 202 can abut against the peripheral wall of the positioning column 22, so as to limit the movement of the positioning column 22 in other directions perpendicular to the vertical direction (for example, the first horizontal direction and the second horizontal direction). The base 10 can indirectly achieve the acceptance of the material box 200 through the acceptance of the positioning seat 21 on the material box 200.

[0084] It is understood that the number of positioning holes 202 can be greater than or equal to the number of positioning posts 22. When the number of positioning holes 202 is greater than the number of positioning posts 22, when each positioning seat 21 abuts against the bottom of the magazine 200, some positioning holes 202 accommodate corresponding positioning posts 22, and the remaining positioning holes 202 are empty.

[0085] Exemplarily, each positioning seat 21 may abut against a corresponding convex strip 204 to receive the material box 200 .

[0086] In other embodiments, a plurality of positioning grooves 211 may be provided on each row of positioning seats 21 at intervals along the second horizontal direction, and each positioning groove 211 may accommodate an elastic member and a positioning column 22 .

[0087] In some embodiments, the tensioning assembly 30 may include a tensioning driver 31 and two tensioning members 32. The tensioning driver 31 is fixedly mounted on the base 10 and is located between the two positioning seats 21. The tensioning driver 31 is spaced apart from the two positioning seats 21 in the first horizontal direction. The two tensioning members 32 are fixedly mounted on two movers of the tensioning driver 31. The tensioning driver 31 can drive the two tensioning members 32 to move closer to or away from each other in the first horizontal direction.

[0088] It can be understood that a part of the structure of each tensioning member 32 can enter the corresponding groove 203 and can abut against the top wall of the corresponding groove 203 in the vertical direction to receive the material box 200 from the bottom.

[0089] Each tensioning member 32 can also abut against the side wall of the corresponding groove 203 in the first horizontal direction, and the side wall of each groove 203 abutting against the tensioning member 32 is located on the side of each groove 203 away from the other groove 203. In this way, the two tensioning members 32 are away from each other and abut against the side walls of the corresponding grooves 203, and the movement of the material box 200 in the first horizontal direction can be limited by tensioning.

[0090] In the embodiment of the present application, there is no specific limitation on the type of the tensioning driver 31. For example, the tensioning driver 31 may be, but is not limited to, a linear motor, a rodless cylinder, and the like.

[0091] In some embodiments, each tensioning member 32 may include a moving portion 321 and a first abutting portion 322. The moving portion 321 may be fixedly connected to the mover of the tensioning driver 31. The side of the moving portion 321 facing away from the tensioning driver 31 in the vertical direction may enter the groove 203 and abut against the top wall of the groove 203. The abutting portion is fixedly connected to the side of the corresponding moving portion 321 facing away from the other moving portion 321. The side of the first abutting portion 322 facing away from the tensioning driver 31 in the vertical direction may enter the groove 203 and abut against the top wall of the groove 203.

[0092] The first abutting portion 322 may include a first sub-portion 3221 and a second sub-portion 3222. The first sub-portion 3221 is fixedly connected to the corresponding moving portion 321. The side of the first sub-portion 3221 that is away from the tensioning driver 31 in the vertical direction may enter the groove 203 and abut against the top wall of the groove 203. The second sub-portion 3222 may be convexly arranged on the side of the first sub-portion 3221 that is away from the moving portion 321 in the first horizontal direction. The thickness of the second sub-portion 3222 in the vertical direction is less than the thickness of the first sub-portion 3221 in the vertical direction. The side of the second sub-portion 3222 that is away from the tensioning driver 31 in the vertical direction is parallel to the side of the first sub-portion 3221 that is away from the tensioning driver 31 in the vertical direction. The second sub-portion 3222 can enter the groove 203 and abut against the top wall of the groove 203; and the side of the second sub-portion 3222 away from the first sub-portion 3221 can abut against the side wall of the groove 203 in the first horizontal direction to achieve the limiting of the tensioning member 32 on the material box 200.

[0093] Exemplarily, the second sub-portion 3222 can enter the portion of the corresponding groove 203 located in the convex strip 204 , and the side of the first sub-portion 3221 facing away from the moving portion 321 and the side of the corresponding convex strip 204 facing the other convex strip 204 .

[0094] It can be understood that when the two second sub-portions 3222 enter the corresponding portion of the groove 203 located in the ridge 204, the top wall and the bottom wall of the portion of the groove 203 in the ridge 204 in the vertical direction can block the corresponding second sub-portion 3222 to limit the relative movement of the material box 200 and the tensioning member 32 in the vertical direction. In this way, the tensioning member 32 can limit the position of the material box 200 in the vertical direction and the first horizontal direction by abutting against the inner wall of the groove 203.

[0095] Please also read Figure 7 In some embodiments, the tensioning assembly 30 may further include at least one slide rail 33 and at least two sliders 34. The slide rail 33 may be fixedly connected to the base 10 and located on one side of the tensioning driver 31 in the second horizontal direction. The slide rail 33 may be spaced apart from the tensioning driver 31. Two sliders 34 are slidably connected to each slide rail 33 in the first horizontal direction. On one slide rail 33, each slider 34 may be fixedly connected to one tensioning member 32.

[0096] In the embodiments of the present application, there is no specific limitation on the number of the slide rails 33. Figure 7 As shown, there can be two slide rails 33 , and the two slide rails 33 are respectively located on both sides of the tensioning drive 31 in the second horizontal direction. Each tensioning member 32 is fixedly connected to a slider 34 on each slide rail 33 .

[0097] It can be understood that the slider 34 can be fixedly connected to the moving portion 321 or the first sub-portion 3221 in the corresponding tensioning member 32, and the embodiments of the present application are not limited to this.

[0098] It can be understood that the slider 34 can bear the corresponding tensioning member 32 to reduce the load on the mover of the tensioning driver 31. The movement of the slider 34 on the slide rail 33 can limit the movement track of the tensioning member 32, reduce the shaking of the tensioning member 32 during the movement, and improve the smoothness of the movement of the tensioning member 32, thereby improving the smoothness of the tensioning member 32 moving into the groove 203 and limiting the position of the material box 200.

[0099] In some embodiments, the stop assembly 40 may include a support member 41, a rotating shaft 42, a stop arm 43 and a stop drive member 44. The number of the support members 41 may be two. The two support members 41 may be fixedly mounted on the base 10. The two support members 41 may be located on one side of the tension drive member in the second horizontal direction and spaced apart from the tension drive member. The rotating shaft 42 may extend along the first horizontal direction and be rotationally connected to each support member 41. The stop arm 43 may include two rotating portions 431 and a second abutting portion 432. One end of the two rotating portions 431 may be fixedly connected to the rotating shaft 42, thereby realizing a rotational connection with the support member 41 through the rotating shaft 42. The second abutting portion 432 may be fixedly connected to the other end of the two rotating portions 431, and the two rotating portions 431 are respectively located at the two ends of the second abutting portion 432 in the first horizontal direction. The stop drive member 44 may be fixedly mounted on the base 10 and connected to the stop arm 43. The abutment driving member 44 can drive the abutment arm 43 to rotate, so that the second abutment portion 432 abuts against the cover plate 201 or the sheet material.

[0100] It can be understood that the stop driving member 44 can be directly connected to the stop arm 43, or can be connected to the stop arm 43 through a connecting structure, and the embodiments of the present application are not limited to this.

[0101] It can be understood that when the material box 200 is supported by the positioning assembly 20 and the tensioning assembly 30, the opening and the cover plate 201 are both arranged toward the abutment assembly 40. The abutment arm 43 can abut against the cover plate 201, thereby limiting the relative movement of the cover plate 201 and the material box 200 by pressing the cover plate 201. At the same time, the abutment arm 43 can abut against the sheet material in the material box 200, thereby limiting the movement of the sheet material by directly pressing the sheet material, and both can prevent the sheet material in the material box 200 from accidentally moving out of the material box 200.

[0102] It can be understood that the axial direction of the rotating shaft 42 can coincide with the first horizontal direction, so that the axial direction of the rotating center axis of the stop arm 43 coincides with the first horizontal direction.

[0103] It is understood that the rotational connection can be realized by a rotating member, which is a connection mode that allows two components to rotate relative to each other. In the embodiments of the present application, the type of the rotating member is not specifically limited. For example, the rotating member can be, but is not limited to, a bearing, a hinge, a hinge, a shaft, etc.

[0104] In some embodiments, the stop drive 44 may include a stop drive 441, a connecting column 442 and a linkage arm 443. The mover of the stop drive 441 can move back and forth in the vertical direction. The stator of the stop drive 441 is fixedly mounted on the base 10. The connecting column 442 is provided with the mover of the stop drive 441 in the first horizontal direction. The linkage arm 443 is fixedly connected to the rotating shaft 42, thereby realizing the connection with the stop arm 43. A linkage groove 4431 is provided on the linkage arm 443. The linkage groove 4431 penetrates the linkage arm 443 in the first horizontal direction. The length direction of the linkage arm 443 is perpendicular to the first horizontal direction, and the linkage groove 4431 extends along the length direction of the linkage arm 443. The connecting column 442 can be provided with a linkage groove 4431 along the first horizontal direction, thereby realizing the connection between the linkage arm 443 and the stop drive 441. The connecting column 442 can slide and cooperate with the inner wall of the linkage groove 4431 along the length direction of the linkage arm 443 , and can slide and cooperate with the inner wall of the linkage groove 4431 along the circumferential direction of the connecting column 442 .

[0105] It can be understood that when the stop driver 441 is working, the mover of the stop driver 441 moves in the vertical direction, which can drive the connecting column 442 to move in the vertical direction. When the connecting column 442 moves, it moves in the linkage groove 4431, and can push the linkage arm 443 and the rotating shaft 42 to rotate, so that the stop arm 43 rotates synchronously. In this way, when the stop driver 441 is working, the linear movement of the mover can drive the rotation of the stop arm 43, so that the stop arm 43 can be close to or away from the material box 200.

[0106] It can be understood that the connecting column 422 can be fixedly connected to the mover of the stop driver 411, or can be rotatably connected to the mover of the stop driver 411, and the embodiments of the present application are not limited to this.

[0107] In the embodiment of the present application, there is no specific limitation on the type of the stop driver 441. For example, the stop driver 441 may be, but is not limited to, a cylinder, a linear motor, etc. Exemplarily, the stop driver 441 may be a cylinder, the mover of the stop driver 441 is a piston rod of the cylinder, and the stator is a cylinder body of the cylinder.

[0108] In the embodiment of the present application, there is no specific limitation on the number of linkage arms 443. For example, a plurality of linkage arms 443 may be arranged at intervals in the first horizontal direction, and the connecting column 442 may be provided with linkage slots 4431 of a plurality of linkage arms 443.

[0109] In the first scenario, when the clamping mechanism 1022 provided in the embodiment of the present application is working, the staff or the robotic arm in the processing equipment 100 can place the material box 200 covered with the cover plate 201 on the tensioning member 32 and the positioning seat 21, so that the positioning column 22 enters the corresponding positioning hole 202, and then the tensioning driver 31 can drive the two tensioning members 32 to move, so that each tensioning member 32 abuts against the side wall in the corresponding groove 203 to limit the material box 200.

[0110] After the tensioning driver 31 works or while the tensioning driver 31 works, the stop driver 441 works to drive the connecting column 442 to move in the vertical direction, so that the linkage arm 443 rotates, thereby driving the stop arm 43 to rotate synchronously. The stop arm 43 can be pressed on the cover plate 201, thereby limiting the movement of the cover plate 201. After the positioning column 22 enters the corresponding positioning hole 202, the tensioning member 32 abuts against the corresponding side wall of the groove 203, and the stop arm 43 presses on the cover plate 201, the moving mechanism 1021 of the transfer device 102 can drive the clamping mechanism 1022 and the material box 200 to move and / or rotate synchronously, so that the material box 200 enters or moves out of the coating device 101.

[0111] In the second scenario, when the clamping mechanism 1022 provided in the embodiment of the present application is working, the cover plate 201 is not provided on the material box 200. After the tensioning assembly 30 and the positioning assembly 20 receive and limit the material box 200, the stop arm 43 can approach the sheet material installed in the material box 200 through the opening on the material box 200 and press on the sheet material, and then the moving mechanism 1021 of the transfer device 102 can drive the clamping mechanism 1022 and the material box 200 to move and / or rotate synchronously, so that the material box 200 enters or moves out of the coating device 101.

[0112] It can be understood that, through the clamping mechanism 1022, the transfer device 102 and the processing equipment 100 provided in the embodiment of the present application, the clamping mechanism 1022 can fix the material box 200, and the transfer device 102 can move the material box 200 after the clamping mechanism 1022 fixes the material box 200. In this way, the movement of the material box 200 can be achieved through an automated device, reducing the workload of the staff in moving the material box 200, improving the convenience of the staff's work and the efficiency of the film coating processing of the sheet material. In addition, the stop arm 43 of the transfer device 102 can press the sheet material in the material box 200 or the cover plate 201 of the material box 200, so as to prevent the sheet material from falling when the transfer device 102 transports the material box 200 loaded with sheet material.

[0113] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, no matter from which point of view, the above embodiments of the present application should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the attached claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.
