Description

Technical Field

[0001] This application relates to the field of photovoltaic material processing, specifically to a positioning tooling and loading / unloading equipment. Background Technology

[0002] When loading and unloading photovoltaic materials, positioning fixtures are needed to support and position the boat so that the photovoltaic materials inside the boat can be inserted and removed. Traditionally, positioning fixtures of different lengths are required to position the boat for boats of different lengths, which increases costs. Utility Model Content

[0003] In view of this, this application provides a positioning fixture capable of positioning boats of different lengths.

[0004] One embodiment of this application provides a positioning fixture, including a base, a bearing assembly, a first driving member, and a clamping assembly. The base has a first stop. The bearing assembly is disposed on the base and includes a bearing surface, a first positioning member, and a second positioning member. The first and second positioning members are spaced apart on the bearing surface along a first direction. The bearing surface is used to bear a workpiece. The second positioning member is movable relative to the bearing surface and is used to insert the workpiece to position it along a second direction, which is perpendicular to the first direction. The first driving member is disposed on the base, connected to the second positioning member, and used to drive the second positioning member to move relative to the bearing surface along the first direction to insert workpieces of different lengths along the first direction. The clamping assembly includes a second driving member and a clamping member. The second driving member is connected to the clamping member and used to drive the clamping member to move along the first direction to push the workpiece in the bearing surface against the first stop, thereby positioning the workpiece along the first direction.

[0005] In the embodiments of this application, a first driving member drives a second positioning member to move relative to the bearing surface along a first direction, thereby adjusting the distance between the first and second positioning members in the first direction. This allows the first and second positioning members to position a workpiece of a certain length in the first direction onto the bearing surface, preventing the workpiece from moving along the second direction, thus positioning the workpiece along the second direction. The second driving member drives a clamping member to move along the first direction, pushing the workpiece in the bearing surface against a first stop member, thereby clamping and positioning the workpiece along the first direction. Therefore, by positioning the workpiece in two perpendicular directions using the first positioning member, the second positioning member, the first stop member, and the clamping member, the workpiece can be positioned on the bearing surface, enabling the positioning fixture to carry and position workpieces of different lengths.

[0006] In some embodiments of this application, a mounting plate is slidably provided on the bearing surface, and the second positioning member and the second driving member are both provided on the mounting plate. The clamping member can move relative to the mounting plate so as to move relative to the mounting plate along a first direction under the drive of the second driving member. The mounting plate is used to connect to the first driving member so as to drive the second positioning member and the clamping assembly to move along the first direction under the drive of the first driving member.

[0007] In some embodiments of this application, the positioning fixture further includes a third driving member, which is disposed on the base and connected to the bearing assembly. The third driving member is used to drive the bearing assembly to move relative to the base in a first direction, so that the workpiece in the bearing surface contacts the first stop member.

[0008] In some embodiments of this application, the workpiece is provided with two grooves, each groove including a bottom surface and two side surfaces, the two side surfaces being spaced apart along a second direction, the bottom surface being perpendicular to the two side surfaces, a first positioning member and a second positioning member being respectively inserted into one groove and used to support the bottom surface; the base is also provided with a second stop member, and the positioning fixture also includes a fourth driving member, the fourth driving member being used to push the workpiece against the second stop member along the second direction to clamp the opposite sides of the workpiece along the second direction.

[0009] In some embodiments of this application, both the first positioning member and the second positioning member include a support portion and a first roller. The support portion is disposed on the bearing surface, and the first roller is rotatably disposed on the support portion. The first roller extends along a first direction to insert into the workpiece.

[0010] In some embodiments of this application, each first positioning member and each second positioning member includes two or more first rollers, and in the first positioning member or the second positioning member, the two or more first rollers are spaced apart along the second direction.

[0011] In some embodiments of this application, the clamping member includes a connecting plate and at least two rubber blocks. The at least two rubber blocks are spaced apart on the connecting plate along a second direction. The connecting plate is used to connect to a second driving member so that the rubber blocks are driven to move along a first direction under the drive of the second driving member, thereby causing the rubber blocks to push the workpiece against the first stop member.

[0012] In some embodiments of this application, the bearing surface is provided with a first slide rail, which extends along a first direction and is used to connect the mounting plate to guide the mounting plate to move along the first direction under the drive of the first driving member.

[0013] In some embodiments of this application, the base is provided with a second slide rail that extends along a first direction. The second slide rail is used to connect the support component to guide the support component to move along the first direction under the drive of the third drive member.

[0014] An embodiment of this application also provides a loading and unloading device, including a conveying component and a positioning fixture as in the previous embodiment. The conveying component is connected to the positioning fixture and is used to drive the positioning fixture to move along a first direction.

[0015] In the embodiments of this application, after the workpiece is positioned by the positioning fixture, the conveying component conveys the positioning fixture and the workpiece along the first direction, which can prevent the workpiece from shaking or shifting during the conveying process.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0028] This application provides a positioning fixture, including a base, a support assembly, a first driving member, and a clamping assembly. The base has a first stop. The support assembly is disposed on the base and includes a support surface, a first positioning member, and a second positioning member. The first and second positioning members are spaced apart on the support surface along a first direction. The support surface supports a workpiece, and the second positioning member is movable relative to the support surface. The first and second positioning members are used to insert the workpiece to position it along a second direction, which is perpendicular to the first direction. The first driving member is disposed on the base, connected to the second positioning member, and used to drive the second positioning member to move relative to the support surface along the first direction to insert workpieces of different lengths along the first direction. The clamping assembly includes a second driving member and a clamping member. The second driving member is connected to the clamping member and used to drive the clamping member to move along the first direction to push the workpiece in the support surface against the first stop, thereby positioning the workpiece along the first direction.

[0029] In the embodiments of this application, a first driving member drives a second positioning member to move relative to the bearing surface along a first direction, thereby adjusting the distance between the first and second positioning members in the first direction. This allows the first and second positioning members to position a workpiece of a certain length in the first direction onto the bearing surface, preventing the workpiece from moving along the second direction, thus positioning the workpiece along the second direction. The second driving member drives a clamping member to move along the first direction, pushing the workpiece in the bearing surface against a first stop member, thereby clamping and positioning the workpiece along the first direction. Therefore, by positioning the workpiece in two perpendicular directions using the first positioning member, the second positioning member, the first stop member, and the clamping member, the workpiece can be positioned on the bearing surface, enabling the positioning fixture to carry and position workpieces of different lengths.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please see Figure 1 One embodiment of this application provides a positioning fixture 100 and a loading / unloading device (not shown). The loading / unloading device includes a conveying assembly 210 and a positioning fixture 100. The conveying assembly 210 is connected to the positioning fixture 100 and is used to drive the positioning fixture 100 to move along a first direction X, so as to load or unload the positioning fixture 100.

[0032] In some embodiments, the loading and unloading equipment includes a robotic arm (not shown) and a wafer insertion / removal assembly (not shown). The conveying assembly 210 can drive the positioning fixture 100 to move between a boat placement position and a wafer insertion / removal position. When the conveying assembly 210 drives the positioning fixture 100 to the boat placement position, the robotic arm places the workpiece 300 within the positioning fixture 100. After the positioning fixture 100 positions the workpiece 300, the conveying assembly 210 drives the positioning fixture 100 and the workpiece 300 to the wafer insertion / removal position, where the wafer insertion / removal assembly removes the photovoltaic material from the workpiece 300.

[0033] In some embodiments, workpiece 300 is a boat. The photovoltaic material is a silicon wafer. The boat is used to load multiple stacked silicon wafers.

[0034] The positioning fixture 100 is used to position the workpiece 300 to prevent the workpiece 300 from shaking and causing the insert and pick-up assembly to break during the pick-up process.

[0035] Please combine Figure 2In some embodiments, the conveying assembly 210 includes a power component 2101, a transmission component 2102, and a support guide component 2103. The power component 2101 is connected to the transmission component 2102, which is connected to the bottom of the positioning fixture 100. The support guide component 2103 is connected to the bottom of the positioning fixture 100, and the transmission component 2102 and the support guide component 2103 are spaced apart along a second direction Y. The power component 2101 drives the transmission component 2102 to move the positioning fixture 100 along a first direction X between a boat placement position and a piece insertion position. The support guide component 2103 extends along the first direction X to support the positioning fixture 100 as it moves along the first direction X, preventing the positioning fixture 100 from tilting or wobbling.

[0036] In some embodiments, the power component 2101 is an electric motor. The transmission component 2102 is a lead screw module, a linear drive module, or a slide cylinder. This application does not limit the choice of which component to be used, and those skilled in the art can make the selection according to the actual situation.

[0037] In some embodiments, the support guide 2103 is a linear guide rail.

[0038] Please see Figure 1 In some embodiments, the positioning fixture 100 includes a base 10, a support assembly 20, a first drive member 30, and a clamping assembly 40. The bottom of the base 10 is used to connect the transmission member 2102 and the support guide member 2103 (see figure). Figure 2 The upper surface of the base 10 is used to mount the bearing assembly 20 and the first drive member 30. The bearing assembly 20 is used to carry the workpiece 300, and the clamping assembly 40 is used to position the workpiece 300 along the first direction X.

[0039] Please see Figure 1 and Figure 3 The support assembly 20 includes a support surface 21, a first positioning member 22, and a second positioning member 23. The support surface 21 is used to support the workpiece 300. The first positioning member 22 and the second positioning member 23 are spaced apart on the support surface 21 along a first direction X. Both the first positioning member 22 and the second positioning member 23 are used to insert the workpiece 300 along the first direction X to position the workpiece 300 along the second direction Y.

[0040] The first positioning member 22 is fixedly disposed on the bearing surface 21, and the second positioning member 23 can move relative to the bearing surface 21 along the first direction X. The first driving member 30 is mounted on the base 10 and connected to the second positioning member 23. When the length of the workpiece 300 along the first direction X changes, the first driving member 30 drives the second positioning member 23 to move relative to the bearing surface 21 along the first direction X, thereby changing the distance between the first positioning member 22 and the second positioning member 23 along the first direction X, so that the first positioning member 22 and the second positioning member 23 can be inserted into workpieces 300 of different lengths.

[0041] The base 10 is provided with a first stop 11. The clamping assembly 40 includes a second drive member 41 and a clamping member 42. The second drive member 41 is connected to the clamping member 42 and is used to drive the clamping member 42 to move along the first direction X, so as to push the workpiece 300 in the bearing surface 21 against the first stop 11, so that the clamping member 42 and the first stop 11 clamp the workpiece 300 on opposite sides along the first direction X, thereby positioning the workpiece 300 on both sides along the first direction X.

[0042] In some embodiments, the second direction Y is perpendicular to the first direction X. The first direction X is the length direction of the base 10. The second direction Y is the width direction of the base 10.

[0043] Along the first direction X, for workpieces 300 of different lengths, the position of the second positioning member 23 is adjusted by the first driving member 30, so that both the first positioning member 22 and the second positioning member 23 can be inserted into the workpiece 300 along the first direction X, thereby positioning the workpiece 300 along the second direction Y. The clamping member 42 is driven by the second driving member 41 to push the workpiece 300 against the first stop member 11, so that the clamping member 42 and the first stop member 11 can clamp the workpiece 300 along the first direction X, thereby positioning the workpiece 300 along the first direction X. Therefore, by positioning the workpiece 300 in two perpendicular directions by the first positioning member 22, the second positioning member 23, the first stop member 11 and the clamping member 42, the workpiece 300 can be positioned on the bearing surface 21, so that the positioning fixture 100 can bear and position workpieces 300 of different lengths.

[0044] In some embodiments, the first stop 11 is fixedly disposed on the base 10. Along the first direction X, the position of the workpiece 300 relative to the base 10 can be positioned by the first stop 11. When the conveying assembly 210 drives the positioning fixture 100 to move, the base 10 drives the workpiece 300 to the wafer insertion position so that the wafer insertion assembly can accurately grasp the silicon wafer.

[0045] Please see Figure 3 and Figure 4 In some embodiments, a mounting plate 24 is slidably provided on the bearing surface 21. The second positioning member 23 is fixedly disposed on the mounting plate 24. The mounting plate 24 is used to connect the first driving member 30 so that, under the drive of the first driving member 30, the second positioning member 23 and the clamping assembly 40 move along the first direction X.

[0046] The first driving component 30 drives the mounting plate 24 to move the second positioning component 23, thereby adjusting the distance between the first positioning component 22 and the second positioning component 23 along the first direction X, so that the first positioning component 22 and the second positioning component 23 can be inserted into the workpiece 300.

[0047] In some embodiments, the second driving member 41 is fixedly disposed on the mounting plate 24, and the clamping member 42 is movable relative to the mounting plate 24 so as to move relative to the mounting plate 24 in the first direction X under the drive of the second driving member 41, thereby pushing the workpiece 300 against the first stop member 11.

[0048] When adjusting the distance between the first positioning member 22 and the second positioning member 23, the clamping assembly 40 moves together with the mounting plate 24, which can initially adjust the position of the clamping member 42 so that the distance between the clamping member 42 and the first stop member 11 can accommodate the workpiece 300. That is, the clamping member 42 is close to the workpiece 300 and located on the side of the workpiece 300 facing away from the first stop member 11. This saves the step of separately adjusting the clamping assembly 40 to make the distance between the clamping member 42 and the first stop member 11 accommodate the workpiece 300, which helps to improve efficiency. Furthermore, since the clamping member 42 moves with the mounting plate 24 to a position close to the workpiece 300, when the second driving member 41 drives the clamping member 42 to move relative to the mounting plate 24, the clamping member 42 can move a shorter distance to abut the side of the workpiece 300 facing away from the first stop member 11, saving the distance that the second driving member 41 needs to drive the clamping member 42 to move.

[0049] In some embodiments, the clamping member 42 includes a connecting plate 421 and two rubber blocks 422. The two rubber blocks 422 are spaced apart along a second direction Y and fixedly disposed on the connecting plate 421. The connecting plate 421 is used to connect to a second driving member 41, so that under the drive of the second driving member 41, the rubber blocks 422 are moved along a first direction X, thereby causing the rubber blocks 422 to push the workpiece 300 against the first stop member 11.

[0050] The rubber blocks 422, being relatively soft, push against the workpiece 300, preventing rigid collisions that could damage the workpiece 300. The two rubber blocks 422 also push against the workpiece 300 at both ends along the second direction Y, preventing the workpiece 300 from tilting during movement along the first direction X.

[0051] Please see Figure 3 and Figure 5 In some embodiments, the first stop 11 includes a fixed plate 111 and two stop posts 112, with the fixed plate 111 fixedly connected to the base 10. The two stop posts 112 are spaced apart along the second direction Y and fixedly disposed on the fixed plate 111. In the first direction X, each rubber block 422 corresponds one-to-one with each stop post 112 to more stably clamp the workpiece 300 on opposite sides along the first direction X.

[0052] In some embodiments, a sensor 14 is provided on the base 10 and mounted on the fixing plate 111. The sensor 14 is used to sense the distance between the workpiece 300 and the fixing plate 111 to determine whether the workpiece 300 is abutting the stop post 112. In the illustrated embodiment, the sensor 14 is a capacitive sensor.

[0053] Please see Figure 3 and Figure 4 In some embodiments, the positioning fixture 100 further includes a third driving member 50. The third driving member 50 is disposed on the base 10. The third driving member 50 is connected to the bearing assembly 20 and is used to drive the bearing assembly 20 to move relative to the base 10 in a first direction X, so that the workpiece 300 in the bearing surface 21 contacts the first stop member 11.

[0054] The third driving member 50 drives the bearing assembly 20 to move along the first direction X, so that the side of the workpiece 300 close to the first positioning member 22 contacts the first stop member 11. This can prevent the workpiece 300 from being too far away from the first stop member 11, making it difficult for the workpiece 300 to be pushed to the first stop member 11 under the drive of the second driving member 41, thus saving the distance that the second driving member 41 needs to drive the clamping member 42 to move.

[0055] Please see Figure 6 In some embodiments, the bottom of the workpiece 300 is provided with two grooves 310. Each groove 310 includes a bottom surface 310a and two side surfaces 310b. The two side surfaces 310b are spaced apart along the second direction Y, and the bottom surface 310a is perpendicular to the two side surfaces 310b. The first positioning member 22 and the second positioning member 23 are respectively inserted into one groove 310 and are used to support the bottom surface 310a.

[0056] Understandably, when the bearing surface 21 bears the workpiece 300, the first positioning element 22 and the second positioning element 23 are respectively located in a groove 310. The first positioning element 22 is located between the two sides 310b of one groove 310, and the second positioning element 23 is located between the two sides 310b of the other groove 310. The first positioning element 22 and the second positioning element 23 support the bottom surface 310a. For ease of description, only the connection between the first positioning element 22 and the groove 310 will be described below. The connection method between the second positioning element 23 and the groove 310 is the same as that of the first positioning element 22, and will not be elaborated here.

[0057] When the size of the workpiece 300 is small, the groove 310 is adapted to the size of the first positioning member 22, and the two sides 310b restrict the movement of the workpiece 300 along the second direction Y to position the workpiece 300 along the second direction Y.

[0058] When the size of the workpiece 300 is large, the groove 310 is larger than the size of the first positioning member 22, and the workpiece 300 can move relative to the first positioning member 22 along the second direction Y.

[0059] Please see Figure 1 and Figure 3 In some embodiments, the base 10 is fixedly provided with a second stop 12. The positioning fixture 100 also includes a fourth drive member 60. When the size of the workpiece 300 is large, the fourth drive member 60 is used to push the workpiece 300 against the second stop 12 along the second direction Y, so that the second stop 12 and the fourth drive member 60 jointly clamp the workpiece 300 on opposite sides along the second direction Y, so as to position the workpiece 300 along the second direction Y.

[0060] When the workpiece 300 has a large dimension along the second direction Y, it can be positioned along the second direction Y by the fourth driving member 60 and the second stop member 12. Therefore, by using the first stop member 11 and the clamping member 42, and the second stop member 12 and the fourth driving member 60, workpieces 300 of different sizes can be positioned and clamped along two perpendicular directions, making the positioning fixture 100 applicable to workpieces 300 of different sizes, with good versatility.

[0061] Please see Figures 3 to 5 In some embodiments, there are two fourth drive members 60. One fourth drive member 60 is disposed on the support assembly 20 and close to the first stop member 11 to push against one end of the workpiece 300 along the second direction Y. The other fourth drive member 60 is disposed on the mounting plate 24 to move with the mounting plate 24 to the other side of the workpiece 300 and push against the other end of the workpiece 300 along the second direction Y. By having two fourth drive members 60 push against the opposite ends of the workpiece 300 along the first direction X, tilting of the workpiece 300 can be prevented during movement along the second direction Y.

[0062] In some embodiments, each fourth drive member 60 is connected to a push block 61. The push block 61 contacts and pushes against the workpiece 300 under the drive of the fourth drive member 60. Compared with the fourth drive member 60 directly pushing against the workpiece 300, the contact area with the workpiece 300 is increased, and the workpiece 300 can be pushed against more stably.

[0063] In some embodiments, the first drive member 30, the second drive member 41, the third drive member 50, and the fourth drive member 60 are all cylinders.

[0064] Please see Figures 3 to 5In some embodiments, both the first positioning member 22 and the second positioning member 23 include a support portion 221 (231) and a first roller 222 (232). In the first positioning member 22, the support portion 221 is fixedly disposed on the bearing surface 21. In the second positioning member 23, the support portion 231 is fixedly disposed on the mounting plate 24. The first roller 222 (232) extends along the first direction X to insert into the groove 310 and support the bottom surface 310a. The first roller 222 (232) is rotatably disposed on a support portion 221 (231), and the axis of rotation of the first ball is parallel to the first direction X. When the fourth driving member 60 pushes the workpiece 300 along the second direction Y, the first roller 222 (232) rotates relative to the support portion 221 (231) and drives the workpiece 300 to move along the second direction Y until the workpiece 300 is pushed against the second stop member 12 (see reference). Figure 6 ).

[0065] Therefore, there is less relative friction between the first roller 222 (232) and the workpiece 300, and the workpiece 300 can be pushed to the second stop 12 more easily.

[0066] In some embodiments, each first positioning member 22 and each second positioning member 23 includes two or more first rollers 222 (232). When the size of the workpiece 300 is small, each first roller 222 (232) contacts one side 310b. When the size of the workpiece 300 is large, the two first rollers 222 (232) are located between the two side 310b.

[0067] In the first positioning member 22 or the second positioning member 23, two or more first rollers 222 (232) are spaced apart along the second direction Y to more stably support the bottom surface 310a of the groove 310. When the fourth driving member 60 pushes against the workpiece 300 along the second direction Y, the two or more first rollers 222 (232) can smoothly drive the workpiece 300 to move along the second direction Y.

[0068] Please see Figures 3 to 5 In some embodiments, the second stop 12 includes a bracket 121 and a second roller 122. The bracket 121 is fixedly mounted on the base 10. The second roller 122 is rotatably mounted on the bracket 121, and the axis of rotation of the second roller 122 is parallel to the first direction X. The second roller 122 is used to abut against the workpiece 300 when the fourth drive member 60 pushes against the workpiece 300 along the second direction Y, thereby clamping the workpiece 300 with the second roller 122 and the fourth drive member 60 along the second direction Y, at which time the first roller 222 (232) stops rotating.

[0069] In some embodiments, the base 10 is provided with a plurality of second stop members 12, which are spaced apart along the first direction X, so as to more stably stop the workpiece 300 when the fourth drive member 60 pushes against the workpiece 300 along the second direction Y.

[0070] Please see Figure 3 and Figure 4 In some embodiments, the bearing surface 21 is fixedly provided with a first slide rail 211. The first slide rail 211 extends along a first direction X. The first slide rail 211 is used to connect the mounting plate 24 to guide the mounting plate 24 to move along the first direction X under the drive of the first driving member 30.

[0071] The first slide rail 211 guides the movement of the mounting plate 24, which can prevent the mounting plate 24 from shifting relative to the first direction X during the movement.

[0072] Please see Figure 7 In some embodiments, the base 10 is provided with a second slide rail 13, which extends along a first direction X. The second slide rail 13 is used to connect the support component 20 to guide the support component 20 to move along the first direction X under the drive of the third drive member 50.

[0073] The second slide rail 13 guides the movement of the mounting plate 24, preventing the load-bearing component 20 from shifting relative to the first direction X during movement.

[0074] In some embodiments, there are two first slide rails 211 and two second slide rails 13. The two first slide rails 211 are spaced apart along the second direction Y to guide the mounting plate 24 to move more smoothly along the first direction X; the two second slide rails 13 are spaced apart along the second direction Y to guide the support assembly 20 to move more smoothly along the first direction X. Connecting the mounting plate 24 via the first slide rails 211 and the support assembly 20 via the second slide rails 13 prevents the mounting plate 24 and the support assembly 20 from tilting relative to the first direction X.

[0075] In some embodiments, the support component 20 is flat to facilitate mounting the support component 20 on the second slide rail 13, and also to facilitate the placement of the first slide rail 211 on the support surface 21 and the connection of the mounting plate 24 to the first slide rail 211.

[0076] Please see Figure 1In use, based on the dimensions of the workpiece 300, the first driving member 30 drives the mounting plate 24 to move away from the first stop member 11 to adjust the distance between the first positioning member 22 and the second positioning member 23, placing the workpiece 300 on the bearing surface 21, with the first positioning member 22 and the second positioning member 23 each bearing the bottom surface 310a of a groove 310. Then, the third driving member 50 drives the bearing assembly 20 to move relative to the base 10 until the workpiece 300 contacts the first stop member 11, initially positioning the workpiece 300. Finally, the second driving member 41 drives the clamping member 42 to move relative to the mounting plate 24 until the clamping member 42 abuts against the workpiece 300, thereby positioning and clamping the workpiece 300 along the first direction X with the clamping member 42 and the first stop member 11. The fourth driving member 60 pushes the workpiece 300 against the second stop member 12 along the second direction Y, thereby positioning and clamping the workpiece 300 along the second direction Y with the fourth driving member 60 and the second stop member 12.
