[0038] Refer to Figure 1, which shows an axial side schematic diagram of a workpiece platform in an embodiment of the present application. The workpiece platform 10 provided in an embodiment of the present application can be opened and closed to adaptively clamp the workpiece 2, thereby reducing the probability of crushing or damaging the workpiece 2 due to excessive squeezing force when clamping the workpiece 2.

[0039] Referring to FIGS. 2 to 4 , a workpiece platform 10 provided in an embodiment of the present application includes a base 100, a clamping assembly 200 and a transmission assembly 300, wherein the transmission assembly 300 is movably disposed on the base 100. The clamping assembly 200 includes a clamping structure 201 and a reset component 202, wherein the clamping structure 201 is movably disposed on the base 100 and can be opened and closed, and the reset component 202 is elastically connected to the clamping structure 201 to drive the clamping structure 201 to elastically close. The transmission assembly 300 includes a rotating member 310 and a pushing member 320, wherein the pushing member 320 is in transmission cooperation with the rotating member 310, and the rotating member 310 is also in transmission cooperation with the clamping structure 201. Among them, when the pushing member 320 is driven, the rotating member 310 is pushed to rotate forward, thereby causing the rotating member 310 to drive the clamping structure 201 to open. The pushing member 320 allows the rotating member 310 to rotate in the opposite direction when the clamping structure 201 is elastically closed.

[0040] In the above-mentioned workpiece platform 10, the pusher 320 and the clamping structure 201 are respectively matched with the rotating member 310 in transmission, so when the pusher 320 is driven, it can push the rotating member 310 to rotate in the forward direction, thereby causing the rotating member 310 to drive the clamping structure 201 to open. In addition, the pusher 320 also allows the rotating member 310 to rotate in the reverse direction, that is, the transmission cooperation between the pusher 320 and the rotating member 310 is a non-self-locking cooperation, so that when the reset member 202 pushes the clamping structure 201 to rotate in the reverse direction, the rotating member 310 and the pusher 320 will hardly hinder the elastic closure of the clamping structure 201. Therefore, when the driving force on the pusher 320 is removed, the reset member 202 can elastically push the clamping structure 201 to close, thereby realizing adaptive clamping and reducing possible damage to the workpiece 2.

[0041] It is easy to understand that, on the first aspect, the reset component 202 has elastic properties. The elastic closure of the above-mentioned clamping structure 201 means that the clamping structure 201 is closed under the action of the elastic driving force of the reset component 202. In the conventional technology, a driving element such as a motor is used to directly drive the workpiece platform 10 to open and close. At this time, if the parameter setting is wrong or the placement of the workpiece 2 is biased, the driving element directly drives the clamping structure 201 to close, which will cause the workpiece 2 to be squeezed and damaged. In contrast, the elastic driving force has an adaptive effect. After the clamping structure 201 is clamped to the physical structure that contacts the workpiece 2 and presses the workpiece 2, it will not be clamped further, thereby reducing the possible damage to the workpiece 2 and improving the versatility of the workpiece platform 10. Furthermore, the size of the elastic driving force of the reset component 202 can be adaptively adjusted so that the clamping structure 201 can take into account both stable clamping of the workpiece 2 and avoiding damage to the workpiece 2. Secondly, the positive and reverse directions of the rotation of the rotating member 310 are only relative. As shown in FIGS. 4 to 8 , the positive direction of the rotation of the rotating member 310 is denoted by O1 , and the reverse direction of the rotation of the rotating member 310 is denoted by O2 .

[0042] Please refer to FIG. 1 again. In one embodiment, the workpiece platform 10 further includes a driver 11. The driver 11 is used to detachably contact the pusher 320 to push the pusher 320 to move. Since the driver 11 and the pusher 320 are detachably in contact, when the driver 11 withdraws the driving force driving the pusher 320, the pusher 320 is no longer driven and does not retreat with the driver 11. At this time, the clamping structure 201 can be elastically closed under the drive of the reset component 202. In addition, the driver 11 only needs to push the pusher 320 to move in one direction, and the driving method is simple.

[0043] Please refer to FIG. 2 to FIG. 4 . In one embodiment, the clamping structure 201 includes a first clamping member 210 and a second clamping member 220 disposed opposite to each other. At least one of the first clamping member 210 and the second clamping member 220 is movably disposed on the base 100 and is in transmission cooperation with the rotating member 310. The reset member 202 elastically drives the movable one of the first clamping member 210 and the second clamping member 220 to approach the other, so that the clamping assembly 200 is elastically closed. For example, the first clamping member 210 may be movably disposed on the base 100 (that is, the first clamping member 210 is the movable one at this time) and is in transmission cooperation with the rotating member 310. When the rotating member 310 rotates forward, it can drive the first clamping member 210 to move in a direction away from the second clamping member 220, so that the clamping structure 201 is opened. When the driver 11 removes the driving force, the reset member 202 elastically drives the first clamping member 210 to move in a direction close to the second clamping member 220, so that the clamping structure 201 is elastically closed.

[0044] Alternatively, the second clamping member 220 may be movably disposed on the base 100 (i.e., the second clamping member 220 is movable in this case) and is in transmission cooperation with the rotating member 310. When the rotating member 310 rotates in the positive direction, it can drive the second clamping member 220 to move away from the first clamping member 210, so that the clamping structure 201 is opened. When the driver 11 removes the driving force, the reset component 202 elastically drives the second clamping member 220 to move toward the first clamping member 210, so that the clamping structure 201 is elastically closed.

[0045] The first clamping member 210 and the second clamping member 220 may also be movably disposed on the base 100 (i.e., both the first clamping member 210 and the second clamping member 220 are movable), and both are in transmission cooperation with the rotating member 310. When the rotating member 310 rotates in the positive direction, it can simultaneously drive the first clamping member 210 and the second clamping member 220 to move away from each other, so that the clamping structure 201 is opened. When the driver 11 removes the driving force, the reset component 202 elastically drives the first clamping member 210 and the second clamping member 220 to move toward each other, so that the clamping structure 201 is closed.

[0046] Further, the reset component 202 can be connected between the first clamping member 210 and the second clamping member 220 to elastically drive the movable one of the first clamping member 210 and the second clamping member 220 to approach the other. Alternatively, the reset component 202 can be connected between the base 100 and the movable one in the clamping structure 201 to drive the movable one to move.

[0047] Please continue to refer to Figures 2 to 4. In one embodiment, the first clamping member 210 and the second clamping member 220 are both movably arranged on the base 100, and the first clamping member 210 and the second clamping member 220 are both transmission-coordinated with the rotating member 310. The reset component 202 may include a first elastic member 230 and a second elastic member 240, and the first elastic member 230 and the second elastic member 240 both have elastic properties. The first elastic member 230 is connected between the first clamping member 210 and the base 100 to elastically push the first clamping member 210 in a direction close to the second clamping member 220. In this way, the first elastic member 230 can drive the clamping structure 201 to elastically close. The second elastic member 240 is connected between the second clamping member 220 and the base 100 to elastically push the second clamping member 220 in a direction close to the first clamping member 210. In this way, the second elastic member 240 can also drive the clamping structure 201 to elastically close.

[0048] It should be noted that, since both the first clamping member 210 and the second clamping member 220 are in transmission cooperation with the rotating member 310, when the first clamping member 210 moves toward the second clamping member 220, the first clamping member 210 will drive the rotating member 310 to rotate in the opposite direction, thereby driving the second clamping member 220 to move toward the first clamping member 210. In short, only the first elastic member 230 or the second elastic member 240 can be provided to drive the first clamping member 210 and the second clamping member 220 to move toward each other. Of course, the first elastic member 230 and the second elastic member 240 can also be provided at the same time to jointly drive the clamping structure 201 to elastically close, so as to improve the stability of the closing movement of the clamping structure 201 and the clamping response speed.

[0049] In one embodiment, the first elastic member 230 and the second elastic member 240 can be configured as compression springs. Of course, the same is true when the first elastic member 230 and the second elastic member 240 are other elements with elastic properties and capable of providing elastic drive.

[0050] Please refer to FIG. 5 and FIG. 6. In one embodiment, the rotating member 310 is configured as a gear, and the pushing member 320 is configured as a rack, that is, the rotating member 310 and the pushing member 320 can adopt a gear meshing transmission mode. The first clamping member 210 includes a first rack 211, and the second clamping member 220 includes a second rack 221. The first rack 211 and the second rack 221 are meshed on opposite sides of the outer periphery of the rotating member 310. In other words, the first clamping member 210 and the second clamping member 220 can also adopt a gear transmission mode to cooperate with the rotating member 310. Therefore, when the driver 11 drives the pushing member 320 to move, the rotating member 310 can be driven to rotate in the positive direction through the gear transmission. When the rotating member 310 rotates in the positive direction, the gear teeth can push the first rack 211 and the second rack 221 to move in opposite directions, so that the first clamping member 210 and the second clamping member 220 move in the direction away from each other, and the clamping structure 201 is opened.

[0051] Further, as shown in Figure 5, along the axis O of the rotating member 310, the first rack 211 and the second rack 221 are staggered with the pushing member 320 to reduce the transmission movement between the pushing member 320 and the rotating member 310, and the transmission movement between the rotating member 310 and the first rack 211 and the second rack 221 interfere with each other.

[0052] As shown in FIG5 , in one embodiment, the rotating member 310 may be configured as a cylindrical gear, and at this time, along the axis O of the cylindrical gear, the first rack 211 and the second rack 221 are arranged in a staggered manner with the pushing member 320. It should be noted that the rotating member 310 is not limited to being configured as a single gear, for example, the rotating member 310 may be a gear set consisting of a plurality of gears connected in series by a transmission shaft (not shown), and at this time, the pushing member 320 and the first rack 211 may be respectively engaged with gears of different sizes and different numbers of teeth, so as to flexibly adjust the transmission ratio.

[0053] It should be further explained that the transmission cooperation between the rotating member 310 and the clamping structure 201 is not limited to the gear rack transmission. For example, referring to FIG. 7 , in one embodiment, the transmission cooperation between the rotating member 310 and the clamping structure 201 can also be carried out by the crank slider transmission. Further, the rotating member 310 is provided with a first crank 311 and a second crank 312, and the first crank 311 and the second crank 312 rotate synchronously around the axis O. The first clamping member 210 can be connected to the first crank 311 through a first connecting rod 215, and the second clamping member 220 can be connected to the second crank 312 through a second connecting rod 225. When the rotating member 310 rotates forward, it can push the first clamping member 210 and the second clamping member 220 to move in a direction away from each other, and the reset component 202 can elastically drive the first clamping member 210 and / or the second clamping member 220 to move in a direction close to each other, so as to drive the rotating member 310 to rotate in the opposite direction. It is easy to understand that what is shown in FIG. 7 is only a simple schematic diagram of the crank slider transmission model between the rotating member 310 and the clamping structure 201, and it is not used to limit the structure and connection relationship of the various components involved. The specific distribution and connection method can be adaptively adjusted according to actual needs.

[0054] Please refer to FIG8 . In one embodiment, the first clamping member 210 further includes a first bottom plate 212, which is connected to the first rack 211. The second clamping member 220 further includes a second bottom plate 222, which is connected to the second rack 221. The first bottom plate 212 is provided with a first slot 212a, and the second bottom plate 222 is provided with a second slot 222a. The first slot 212a is plugged and matched with the second rack 221, and the second slot 222a is plugged and matched with the first rack 211. Thus, the probability of interference between the first clamping member 210 and the second clamping member 220 when they move in the same direction is reduced, so that the overall structure of the workpiece platform 10 can be more compact.

[0055] Further, the clamping structure 201 can be opened and closed along the first direction S1, that is, the first clamping member 210 and the second clamping member 220 both move along the first direction S1. The first rack 211 and the second rack 221 can both extend along the first direction S1, and in the direction perpendicular to the first direction S1 (that is, the second direction S2 mentioned below), the first rack 211 and the second rack 221 are arranged at intervals. The first rack 211 and the first slot 212a are arranged side by side, so that the extension direction of the first slot 212a coincides with the second rack 221, so that the two are plugged in. Similarly, the second rack 221 and the second slot 222a are arranged side by side, so that the extension direction of the second slot 222a coincides with the first rack 211, so that the two are plugged in.

[0056] Please refer to FIG. 4 again. In one embodiment, the first clamping member 210 further includes a first vertical plate 213, which is disposed on the first bottom plate 212. The second clamping member 220 further includes a third vertical plate 223, which is disposed on the second bottom plate 222. The first vertical plate 213 and the third vertical plate 223 are disposed opposite to each other to clamp and position the workpiece 2.

[0057] Please refer to FIGS. 2 to 4 . In one embodiment, one end of the reset component 202 is fixedly connected to the base 100, and the other end of the reset component 202 is connected to the clamping structure 201. The position of the connection part of the reset component 202 on the clamping structure 201 in the first direction S1 is adjustable. By adjusting the position of the connection part of the reset component 202 and the clamping structure 201 in the first direction S1, the opening and closing size of the clamping structure 201 can be adjusted. Taking the connection of the first elastic member 230 with the first bottom plate 212 of the first clamping member 210 as an example, the position of the connection part of the first elastic member 230 on the first bottom plate 212 is adjustable in the first direction S1. As shown in FIGS. 3 and 4 , for the convenience of explanation, the following is an example of the first end 231 of the first elastic member 230 being connected to the base 100, the second end 232 of the second elastic member 240 being connected to the first bottom plate 212, and the position of the second end 232 being adjustable. It is easy to understand that, when the first elastic member 230 remains unchanged, the length of the first elastic member 230 in the original state remains basically unchanged, and the maximum distance that the first elastic member 230 can push the first clamping member 210 to move also remains basically unchanged. Therefore, the farther the connection position of the second end 232 of the first elastic member 230 is from the second clamping member 220, the closer the first elastic member 230 can push the first clamping member 210 to the first clamping member 210.

[0058] Similarly, the position of the connection portion of the second elastic member 240 on the second bottom plate 222 in the first direction S1 is adjustable.

[0059] As shown in FIG. 4 and FIG. 8 , in one embodiment, the sandwich structure 201 further includes a plurality of connecting blocks 203, and the first elastic member 230 can be connected to the first bottom plate 212 through one connecting block 203, and the second elastic member 240 can be connected to the second bottom plate 222 through another connecting block 203. The setting position of the connecting block 203 on the first bottom plate 212 and the second bottom plate 222 is adjustable along the first direction S1 to adjust the position of the second end 232. In conjunction with FIG. 9 , the number of the first elastic member 230 can be two, and the two first elastic members 230 are respectively located on both sides of the first bottom plate 212. The number of the second elastic member 240 can also be two, and the two second elastic members 240 are respectively located on both sides of the second bottom plate 222.

[0060] Please refer to FIG. 9 and FIG. 11 . In one embodiment, the workpiece platform 10 can clamp the workpiece 2 in different clamping ways to cope with different types of workpieces 2. The first clamping member 210 includes a plurality of contact surfaces 210a, at least some of which are staggered with other contact surfaces 210a in the first direction S1 and the second direction S2. The second direction S2 is perpendicular to the first direction S1. The contact surface 210a is used to contact the workpiece 2 and cooperate with the second clamping member 220 to clamp the workpiece 2. Since the contact surfaces 210a are staggered in the first direction S1, the distances from different contact surfaces 210a to the second clamping member 220 are different, so the clamping structure 201 can clamp workpieces 2 of different sizes in the first direction S1. Since the second direction S2 is perpendicular to the first direction S1, different contact surfaces 210a are staggered in the second direction S2, so that each contact surface 210a can be used to clamp the workpiece 2 relatively independently.

[0061] Similar to the first clamping member 210, the second clamping member 220 includes a plurality of mating surfaces 220a, at least some of which are arranged in a staggered manner with other mating surfaces 220a in the first direction S1 and the second direction S2. The mating surfaces 220a are used to contact the workpiece 2 and cooperate with the first clamping member 210 to clamp the workpiece. Since the mating surfaces 220a are arranged in a staggered manner in the first direction S1, the distances from different mating surfaces 220a to the first clamping member 210 are different, so the clamping structure 201 can clamp workpieces 2 of different sizes in the first direction S1. The second direction S2 is perpendicular to the first direction S1, so different mating surfaces 220a are arranged in a staggered manner in the second direction, so that each mating surface 220a can be used to clamp the workpiece 2 relatively independently.

[0062] Regarding the second direction S2, when the workpiece platform 10 is in normal use, the second direction S2 may be parallel to the gravity direction, that is, the second direction S2 may be a vertical direction.

[0063] It should be noted that only the first clamping member 210 may be provided with a contact surface 210a, so that the clamping structure 201 clamps different types of workpieces 2. Alternatively, only the second clamping member 220 may be provided with a mating surface 220a, so that the clamping structure 201 clamps different types of workpieces 2. Alternatively, the first clamping member 210 may be provided with a contact surface 210a, and the second clamping member 220 may be provided with a mating surface 220a, so that the clamping structure 201 clamps different types of workpieces 2. For example, the contact surface 210a and the mating surface 220a may be provided opposite to each other in a one-to-one correspondence, so as to form a clamping group 250, and different clamping groups 250 can clamp different types of workpieces 2. It is easy to understand that the different types of workpieces 2 referred to here mainly refer to having different sizes in the first direction S1.

[0064] Please refer to FIG9 . The clamping group 250 can be divided into a first clamping group 251 and a second clamping group 252. As shown in FIG10 , the first clamping group 251 can be used to clamp a workpiece 2 with a smaller size in the first direction S1. As shown in FIG1 . The second clamping group 252 can be used to clamp a workpiece 2 with a larger size in the first direction S1. When the size of the workpiece 2 in the first direction S1 obviously exceeds the adaptive clamping range of the first clamping group 251, the second clamping group 252 can be used for clamping. Of course, it should be noted that the number of clamping groups 250 is not limited to 2, and the number of clamping groups 250 can also be set to 3, 4, 5 or 6, etc. according to needs.

[0065] Please refer to FIG. 2 , FIG. 11 and FIG. 12 . In one embodiment, the base 100 includes a stand 110 . The stand 110 is recessed along the second direction S2 to form a receiving groove 111 . The bottom wall of the receiving groove 111 and the top surface of the stand 110 are used to support the workpiece 2 . A contact surface 210 a and a matching surface 220 a are disposed opposite to each other and disposed in the receiving groove 111 , so as to cooperate with the bottom wall of the receiving groove 111 to clamp the workpiece 2 . In this embodiment, in the first aspect, the contact surface 210 a and the matching surface 220 a disposed in the receiving groove 111 can be disposed opposite to each other along the first direction S1 , and the two form a first clamping group 251 . Since the receiving groove 111 is provided in the stand 110 , the contact surface 210 a and the matching surface 220 a included in the first clamping group 251 are disposed in the receiving groove 111 , and the distance between the two is relatively small, so that the workpiece 2 with a smaller size in the first direction S1 can be clamped . The contact surface 210a and the matching surface 220a provided outside the stand 110 can be arranged facing each other along the first direction S1, and the two form a second clamping group 252. Since the contact surface 210a and the matching surface 220a included in the second clamping group 252 are provided outside the stand 110, the distance between the two is relatively large, and it can be used to clamp the workpiece 2 with a larger size in the first direction S1. On the second aspect, since the receiving groove 111 is recessed in the stand 110 along the second direction S2, there is a height difference between the bottom wall of the receiving groove 111 and the top surface of the stand 110 in the second direction S2. This embodiment uses different heights of the stand 110 to respectively support the workpiece 2 clamped by different clamping groups 250, so that each clamping group 250 is relatively independent, the probability of mutual interference between different clamping groups 250 is reduced, and the position stability of the workpiece 2 can be improved. Please refer to FIG. 12 , the top surface of the stand 110 is denoted by PL1 , and the bottom wall of the receiving groove 111 is denoted by PL2 . As shown in FIG. 12 , there is a height difference between the top surface of the stand 110 and the bottom wall of the receiving groove 111 in the second direction S2 .

[0066] In conjunction with FIG. 9 and FIG. 11 , in one embodiment, the first clamping member 210 further includes a second vertical plate 214, the first vertical plate 213 and the second vertical plate 214 are arranged on the first bottom plate 212, and the first vertical plate 213 and the second vertical plate 214 are both provided with a contact surface 210a, which is used to cooperate with the second clamping member 220 to clamp the workpiece 2. The first vertical plate 213 and the second vertical plate 214 can be arranged on the first bottom plate 212 at intervals along the first direction S1. The second clamping member 220 further includes a fourth vertical plate 224, the third vertical plate 223 and the fourth vertical plate 224 are arranged on the second bottom plate 222, and the third vertical plate 223 and the fourth vertical plate 224 are both provided with a matching surface 220a, which is used to cooperate with the first clamping member 210 to clamp the workpiece 2. The third vertical plate 223 and the fourth vertical plate 224 can be arranged on the second bottom plate 222 at intervals along the first direction S1.

[0067] Further, the first vertical plate 213 and the third vertical plate 223 are inserted into the receiving groove 111 for clamping the workpiece 2. Along the first direction S1, the first vertical plate 213 and the third vertical plate 223 are arranged opposite to each other, and the contact surface 210a of the first vertical plate 213 and the matching surface 220a of the third vertical plate 223 can form the above-mentioned first clamping group 251. The second vertical plate 214 and the fourth vertical plate 224 are located outside the stand 110 for clamping the workpiece 2. Along the first direction S1, the second vertical plate 214 and the fourth vertical plate 224 are arranged opposite to each other, and the matching surface 220a of the second vertical plate 214 and the fourth vertical plate 224 can form the above-mentioned second clamping group 252. As mentioned above, the first bottom plate 212 is transmission-coordinated with the rotating member 310 through the first rack 211. Since the first vertical plate 213 and the second vertical plate 214 are both arranged on the first bottom plate 212, the first vertical plate 213 and the second vertical plate 214 can move synchronously. Similarly, the second bottom plate 222 is in transmission cooperation with the rotating member 310 through the second rack 221, and the third vertical plate 223 and the fourth vertical plate 224 are both arranged on the second bottom plate 222, so the third vertical plate 223 and the fourth vertical plate 224 can move synchronously. The first vertical plate 213 and the third vertical plate 223 form a first clamping group 251, and the second vertical plate 214 and the fourth vertical plate 224 form a second clamping group 252, so the rotating member 310 can drive the first clamping group 251 and the second clamping group 252 to open synchronously, and the reset component 202 can drive the first clamping group 251 and the second clamping group 252 to close synchronously, so there is no need to set a driving structure for each clamping group 250, so that the workpiece platform 10 has a simple and compact structure.

[0068] Please refer to FIG. 2 , FIG. 11 and FIG. 12 . In one embodiment, the base 100 further includes a base 120. The stand 110 is mounted on the base 120, so that a part of the stand 110 is spaced from the base 120 to form a layer cavity 101, and the transmission assembly 300 is disposed in the layer cavity 101. The first bottom plate 212 and the second bottom plate 222 are disposed in the layer cavity 101 and are in transmission cooperation with the rotating member 310. Thus, the stand 110 can separate the part of the sandwich structure 201 used for transmission connection from the part of the sandwich structure 201 used for positioning and clamping, thereby reducing the risk of mutual influence.

[0069] In conjunction with FIG. 9 and FIG. 11 , regarding the contact surface 210a, the mating surface 220a and each vertical plate, the contact surface 210a and the mating surface 220a can be partial areas on each vertical plate for clamping. As shown in FIG. 4 , further, the clamping structure 201 also includes a buffer pad 260, and the number of the buffer pads 260 is multiple, and the multiple buffer pads 260 are respectively arranged at each contact surface 210a and / or the mating surface 220a. The buffer pad 260 can be made of a flexible material such as rubber, silicone or sponge to reduce the impact and damage to the workpiece 2.

[0070] Please refer to FIG. 13 . In one embodiment, a communication port 113 is formed on the bottom wall of the receiving groove 111 . The communication port 113 is used to communicate with the layer cavity 101 so as to allow the first vertical plate 213 and the third vertical plate 223 to extend into the receiving groove 111 .

[0071] Regarding the accommodating groove 111, when the space in the accommodating groove 111 is large enough, the workpiece 2 can be positioned and fixed in the accommodating groove 111. Or please refer to Figure 13. In one embodiment, at least one of the two side groove walls of the accommodating groove 111 in the third direction S3 is provided with a avoidance opening 112, and the avoidance opening 112 connects the accommodating groove 111 with the outside. The first direction S1, the second direction S2 and the third direction S3 are perpendicular to each other. Part of the structure of the workpiece 2 can extend outward through the accommodating groove 111, so that the workpiece 2 is not limited by the size of the accommodating groove 111. Furthermore, the number of the avoidance openings 112 can be 2, and the two avoidance openings 112 are respectively provided on the two side groove walls of the accommodating groove 111 in the third direction S3.

[0072] Please refer to FIG. 13 . In one embodiment, the base 120 is provided with a first slide rail 121 and a second slide rail 122. The first slide rail 121 extends along a first direction S1, and the clamping structure 201 is slidably matched with the first slide rail 121. Further, the first slide rail 121 may include two sections, and the first clamping member 210 and the second clamping member 220 may be slidably matched with the two sections of the first slide rail 121, respectively. The second slide rail 122 extends along a third direction S3, and the pushing member 320 is slidably matched with the second slide rail 122.

[0073] The base 120 is also embedded with a bearing 126 , and the rotating member 310 is inserted into the inner ring of the bearing 126 . The rotating member 310 rotates with the base 120 through the bearing 126 .

[0074] The base 120 includes a first guide rod 124, a second guide rod 125 and two side plates 123 arranged opposite to each other, and the reset component 202 can be connected between the side plates 123 and the clamping structure 201. The first guide rod 124 is arranged on one of the side plates 123, and the second guide rod 125 is arranged on the other side plate 123. The first elastic member 230 can be sleeved on the first guide rod 124, and the first guide rod 124 can support the first elastic member 230, so that the first elastic member 230 can be stably extended and retracted along the first direction S1. Similarly, the second elastic member 240 can be sleeved on the second guide rod 125, and the second guide rod 125 can support the second elastic member 240, so that the second elastic member 240 can be stably extended and retracted along the first direction S1. Further, one end of the first guide rod 124 is connected to one of the side plates 123, and the other end of the first guide rod 124 can be slidably penetrated through one of the connecting blocks 203. The connection block 203 cooperates with the side plate 123 to limit the first elastic member 230 to the first guide rod 124. Similarly, one end of the second guide rod 125 is connected to another side plate 123, and the other end of the second guide rod 125 can slidably pass through another connection block 203. The connection block 203 cooperates with the side plate 123 to limit the second elastic member 240 to the second guide rod 125.

[0075] Regarding the workpiece platform 10 provided in each embodiment, when in use, the pusher 320 can be driven to move so that the clamping structure 201 is opened to a degree slightly larger than the size of the workpiece 2. The workpiece 2 is placed in the open space of the clamping structure 201. Then the driving force is removed, so that the clamping structure 201 clamps the workpiece 2 adaptively.

[0076] Referring to FIG. 14 , an embodiment of the present application further provides a conveying device 1, which includes a track 1a and a plurality of workpiece platforms 10. The workpiece platform 10 is movably arranged on the track 1a to move along the track 1a. Further, since the driver 11 and the pusher 320 adopt a detachable contact driving mode, the structural correlation between the two is low, so the driver 11 does not need to move with the workpiece platform 10. In one embodiment, a plurality of drivers 11 can be fixedly arranged on the side of the track 1a at intervals to reduce the weight of the moving part of the workpiece platform 10 and improve the agility and flexibility of the movement of the workpiece platform 10. The driver 11 is preset at a specific station 1b. When the workpiece platform 10 moves to the station 1b, the driver 11 can drive the workpiece platform 10 to open to transfer the workpiece 2 or adjust the posture of the workpiece 2. Further, taking the conveying device 1 for use in a detection device as an example, since the workpiece platform 10 has a plurality of clamping groups 250, the workpiece platform 10 can clamp workpieces 2 of different sizes in the first direction S1. When the workpiece platform 10 is used to clamp the workpiece 2 and drive the workpiece 2 to move to the inspection station, in combination with Figures 1 and 10, the workpiece platform 10 can also be used to clamp the same workpiece in different postures to facilitate multi-angle inspection of the workpiece 2.

[0077] Of course, in another embodiment, the driver 11 may also be configured to move together with the workpiece platform 10 . For example, the driver 11 may be disposed on the base 100 .

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application.
