TECHNICAL FIELD

[0001] The present application relates to the technical field of material conveying, in particular to a conveying device and a detection equipment. BACKGROUND

[0002] With the development of science and technology, various devices gradually develop in the direction of refinement and precision. In the traditional technology, products are usually automatically conveyed by a conveyor belt and the like. However, for products with relatively precise or fragile structures, if the traditional conveying belt and the like are used for conveying, the surface of the workpiece is easy to be damaged, which needs to be improved. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a conveying device and a detection equipment to solve the problem that the traditional conveying device cannot be used to convey precise and fragile products.

[0004] The present application provides a conveying device, which comprises a carrier and a transfer assembly. The carrier is provided with a plurality of supporting positions for placing workpieces, and the supporting positions are arranged in sequence along a first direction. The transfer assembly comprises a clamping structure and a driving structure. The clamping structure comprises a limiting piece, and a plurality of limiting pieces are arranged in groups of at least two to form a plurality of fixing positions. The clamping structure is arranged in the carrier, and the fixing positions are located below the corresponding supporting positions. The driving structure can drive the clamping structure to move along the intersecting first and second directions. When the clamping structure is lifted along the second direction, the fixing positions clamp the workpieces in the corresponding supporting positions to separate the workpieces from the carrier. When the clamping structure moves along the first direction, the fixing positions move synchronously to the positions aligned with the adjacent supporting positions.

[0005] In one embodiment, the clamping structure further comprises a plurality of first connecting plates for supporting the workpieces. The limiting pieces forming one fixing position are arranged on the same first connecting plate, and the positions of the limiting pieces on the first connecting plate are adjustable along the first direction.

[0006] In one embodiment, the driving structure comprises a plurality of lifting drivers corresponding to the plurality of first connecting plates to drive the first connecting plates to lift along the second direction.

[0007] In one of the embodiments, the clamping structure comprises sensors, and the sensors are correspondingly arranged at the fixing positions; each of the limiting members forming the same fixing position comprises a first side and a second side which are away from each other, and the limiting member is provided with a through hole extending from the first side to the second side; the sensor comprises a transmitting part arranged at the first side and a receiving part arranged at the second side, and the transmitting part transmits a conductive medium through the fixing position to the receiving part through the through hole, and the conductive medium is used to trigger the sensor when being shielded.

[0008] In one of the embodiments, the clamping structure further comprises a second connecting plate, the driving structure comprises a transverse driving device, and the first connecting plates are movably arranged on the second connecting plate along the second direction; the transverse driving device is connected with the second connecting plate to drive the second connecting plate to move transversely along the first direction.

[0009] In one of the embodiments, the bracket comprises a first support and a second support which extend along the first direction, the first support and the second support are arranged in parallel and spaced apart, the supporting positions are arranged and distributed on the first support and the second support, and the clamping structure is movably arranged in the space between the first support and the second support.

[0010] In one of the embodiments, the first support and the second support are arranged in parallel and spaced apart along a third direction which is perpendicular to the first direction and the second direction, and one side of the first support away from the second support is provided with a positioning part; the transportation device further comprises a positioning structure arranged on one side of the second support away from the first support, and the positioning structure is used to push the workpiece along the third direction to a position contacting the positioning part.

[0011] In one of the embodiments, the transportation device further comprises a distance changing assembly connected with at least one of the first support and the second support to drive the first support and the second support to move towards each other and move away from each other along the third direction.

[0012] In one of the embodiments, the bracket further comprises a plurality of buffer members, and each of the buffer members is correspondingly arranged at each of the supporting positions, and the buffer members are used to support the workpiece.

[0013] Another aspect of the present application further provides a detection device comprising the transportation device as described above.

[0014] The fixed position is arranged below the supporting position before the clamping structure is jacked up, and the fixed position can support the workpiece in the supporting position after the clamping structure is jacked up. In addition, the at least two limiting members forming the fixed position are arranged at intervals along the first direction, so that when the clamping structure moves along the first direction, the limiting members can support the workpiece on both sides to drive the workpiece to move and reduce the probability of shaking of the workpiece in the first direction during the movement of the workpiece along the first direction with the clamping structure. Further, the clamping structure uses the jacking-up mode to clamp the workpiece in the supporting position, so that the workpiece enters the fixed position. During the jacking-up and transverse movement, the limiting members are mainly supported on both sides of the workpiece, and there is almost no clamping force on the workpiece, so that the risk of clamping and crushing the workpiece can be reduced. It is easy to understand that the clamping structure provided by the application drives the workpiece to move by using the upward jacking force of the clamping structure and the supporting force of the limiting members, rather than using friction force like a conveyor belt, and there is no normal pressure when the clamping jaw clamps and lifts the workpiece, so that the damage that the workpiece may suffer during the conveying process can be greatly reduced, and the workpiece can be fully protected during the conveying process. Therefore, the conveying device can be adapted to convey precise and easily damaged workpieces. BRIEF DESCRIPTION OF DRAWINGS

[0032] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0033] In this application, unless otherwise explicitly specified and limited, if there are terms such as "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited.

The first feature "below", "below" and "below" of the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0036] One embodiment of the present application provides a transport device for transporting a workpiece along a predetermined direction (i.e., a first direction, referred to below). The transport device is less likely to damage the workpiece during transport and is therefore suitable for transporting delicate or delicate workpieces requiring high surface precision, such as battery packs.

[0037] See Figures 1 to 3 In one embodiment, the transport device 10 includes a bracket 100 and a transfer assembly 200. The bracket 100 is provided with a plurality of supporting positions 101 for placing workpieces 20, and the plurality of supporting positions 101 are arranged in sequence along the first direction S1. The transfer assembly 200 includes a clamping structure 210 and a driving structure 220, and the driving structure 220 can drive the clamping structure 210 to move along the intersecting first direction S1 and second direction S2. The clamping structure 210 includes a limiting member 211, and the plurality of limiting members 211 are spaced apart in groups of at least two to form a plurality of fixed positions 210a. The clamping structure 210 is provided through the bracket 100, and the fixed position 210a is correspondingly located below the supporting position 101. When the clamping structure 210 is lifted along the second direction S2, the fixed position 210a is used to clamp the workpiece 20 at the corresponding supporting position 101 to separate the workpiece 20 from the bracket 100. When the clamping structure 210 moves along the first direction S1 , each fixing portion 210 a moves synchronously to a position aligned with another adjacent supporting portion 101 .

[0038] The transport device 10, before the clamping structure 210 is jacked up, the fixed position 210a is correspondingly arranged below the supporting position 101, and after the jacking up, the fixed position 210a can support the workpiece 20 located in the supporting position 101. Moreover, the at least two limit pieces 211 forming the fixed position 210a are arranged at intervals along the first direction S1, so that when the clamping structure 210 moves along the first direction S1, the limit pieces 211 can support on both sides of the workpiece 20 to drive the workpiece to move, and reduce the probability of shaking of the workpiece 20 in the first direction S1 during the movement of the workpiece 20 along the first direction S1 with the clamping structure 210. Further, the clamping structure 210 adopts the jacking-up mode to clamp the workpiece 20 in the supporting position 101, so that the workpiece 20 enters the fixed position 210a. During the jacking-up and transverse movement, the limit pieces 211 mainly support on both sides of the workpiece 20, and almost have no clamping force on the workpiece 20, so as to reduce the risk of clamping and crushing the workpiece 20. It is easy to understand that the clamping structure 210 provided by the present application drives the workpiece 20 to move by using the upward jacking thrust of itself and the supporting force of the limit pieces 211, rather than using friction force like a conveyor belt, and there is no normal pressure when the clamping jaw clamps and lifts the workpiece, so as to greatly reduce the damage that the workpiece 20 may suffer during the conveying of the workpiece 20, and fully protect the workpiece during the transportation. Therefore, the transport device 10 can be adapted to convey precise and easily damaged workpieces 20.

[0039] Further, when the clamping structure 210 is jacked up, each fixed position 210a clamps the workpiece 20 at the corresponding supporting position 101, and when the clamping structure 210 moves along the first direction S1, each fixed position 210a can be switched to a position that is aligned with another adjacent supporting position 101. Therefore, the transverse movement of the clamping structure 210 can transport the workpiece 20 in each supporting position 101 to the next supporting position 101 in the first direction S1, and simultaneously realize the transportation of multiple workpieces 20, with high transportation efficiency. It is easy to understand that the workpiece 20 can be separated from the bracket 100 after the fixed position 210a clamps the workpiece 20 in the supporting position 101, so that the workpiece 20 will not rub against the bracket 100 when the workpiece 20 moves with the clamping structure 210, thereby reducing the probability of damage to the workpiece 20.

[0040] It should be noted that in the first aspect, the clamping structure 210 moving along the second direction S2 is not limited to lifting along the second direction S2, and the clamping structure 210 can also be lowered along the first direction S1 to place the workpiece 20 at the corresponding support position 101. Similarly, the clamping structure 210 can be moved along the first direction S1 in the forward direction and the reverse direction to cyclically transport the workpiece 20 at one support position 101 to an adjacent another support position 101. The manner in which the transfer assembly 200 provided by the present application transports the workpiece 20 will be described in detail below in combination with the specific structure of the clamping structure 210 and the driving structure 220. In the second aspect, the plurality of limit members 211 are at least two groups of limit members 211 spaced apart to form a plurality of fixed positions 210a, which means that the number of limit members 211 used to form the fixed position 210a can be two, and the two limit members 211 are spaced apart to form the fixed position 210a for receiving and positioning the workpiece 20; and the number of limit members 211 used to form the fixed position 210a can also be more than two, and at this time, part of the limit members 211 are located on one side, and another part of the limit members 211 are located on the opposite side, and the two parts of the limit members 211 are spaced apart to form the fixed position 210a for receiving and positioning the workpiece 20.

[0041] As Figure 2 , in one embodiment, the limit members 211 forming the same fixed position 210a can be spaced apart in the first direction S1, so that the plurality of fixed positions 210a formed thereby can correspond to the plurality of support positions 101 arranged along the first direction S1. Further, the plurality of limit members 211 can be sequentially and spaced apart in the first direction S1. For ease of understanding, in the following, among the same group of limit members 211, the limit members 211 located on one side in the first direction S1 are referred to as first limit members 211a, and the limit members 211 located on the other side in the first direction S1 are referred to as second limit members 211b, and the first limit members 211a and the second limit members 211b are spaced apart to form the fixed position 210a. It is easy to understand that the same group of first limit members 211a and second limit members 211b are spaced apart to form the fixed position 210a, and the present application does not limit the positional relationship between adjacent different groups of limit members 211, which can be set according to actual needs. For example Figure 2 , adjacent different groups of limit members 211 can be configured to be spaced apart, so that the workpieces 20 have sufficient spacing therebetween. Or as Figure 4a , adjacent different groups of limit members 211 can also be arranged in a back-to-back manner. Whether the first limit members 211a and the second limit members 211b of adjacent different groups of limit members 211 are spaced apart or not, and the size of the spacing, can be adaptively set according to the needs of the workpieces 20 and the arrangement needs of the support positions 101 and other factors. Further, the present application does not limit that one limit member 211 can only be used to form one fixed position 210a. For example, as Figure 4bIn one embodiment, in the first direction S1, one stopper 211 can be arranged apart from the other two stoppers 211 adjacent thereto to form two fixing positions 210a. At this time, the stopper 211 serves as a first stopper 211a of one of the fixing positions 210a, and also serves as a second stopper 211b of the other fixing position 210a. Along the first direction S1, the two fixing positions 210a are respectively located on the two sides of the stopper 211.

[0042] Referring to Figure 2 and Figure 3 In one embodiment, the clamping structure 210 further comprises a plurality of first connecting plates 212 for supporting the workpiece 20. The stopper 211 forming a fixing position 210a is arranged on the same first connecting plate 212, that is, the number of first connecting plates 212 corresponds to the number of fixing positions 210a, and the stoppers 211 are arranged apart on the first connecting plates 212. The first connecting plate 212 can also be part of the fixing position 210a. Thus, the fixing position 210a formed by the first stopper 211a, the second stopper 211b and the first connecting plate 212 has a top-open box structure, and when the clamping structure 210 is lifted, the workpiece 20 in the supporting position 101 can be received into the fixing position 210a from bottom to top, so that the workpiece 20 is fully supported and positioned, and the risk of damage caused by the displacement of the workpiece 20 during conveying relative to the clamping structure 210 is reduced.

[0043] Further, along the first direction S1, the position of the stopper 211 on the first connecting plate 212 is adjustable. Thus, the size of the fixing position 210a can be adjusted to adapt to workpieces 20 of different sizes. Further, the stopper 211 can be configured to be detachably mounted on the first connecting plate 212, and by detaching and adjusting the mounting position of the stopper 211 on the first connecting plate 212, the size of the fixing position 210a can be adjusted. Alternatively, the stopper 211 can be arranged to be slidably arranged on the first connecting plate 212, and the size of the fixing position 210a can be adjusted by driving the stopper 211 to move by a driver.

[0044] Referring to Figure 3 and Figure 5In one embodiment, the driving structure 220 comprises a lifting driver 221, and a plurality of the lifting drivers 221 are correspondingly connected with the plurality of the first connecting plates 212 to drive the first connecting plates 212 to lift along the second direction S2. Since the same group of the limiting members 211 are arranged on the first connecting plates 212, driving the first connecting plates 212 to lift is equivalent to driving the fixing positions 210a to lift. It can be understood that the clamping structure 210 extends along the first direction S1 as a whole, and the clamping structure 210 has a larger structural size and a larger spatial span in the first direction S1 than in other directions. Therefore, arranging a plurality of lifting drivers 221 to respectively drive a plurality of first connecting plates 212 to move can improve the reliability of the lifting movement of the fixing positions 210a. Of course, all the first connecting plates 212 can also be connected with each other or connected through an intermediate connecting member, and at this time, only one lifting driver 221 can be arranged to drive a plurality of first connecting plates 212 to synchronously lift.

[0045] In one embodiment, the lifting driver 221 can be configured as a linear driver, such as a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0046] Please refer to Figure 5 In one embodiment, the clamping structure 210 further comprises a second connecting plate 213. The driving structure 220 comprises a transverse driving driver 222, and the plurality of the first connecting plates 212 are movably arranged on the second connecting plate 213 along the second direction S2. As described above, the first connecting plates 212 can be driven by the lifting driver 221 to move on the second connecting plate 213. The lifting driver 221 can also be arranged on the second connecting plate 213. The transverse driving driver 222 is connected with the second connecting plate 213 to drive the second connecting plate 213 to move along the first direction S1. In this way, the plurality of the fixing positions 210a can be synchronously moved along the first direction S1 by the transverse driving driver 222, so that each fixing position 210a is synchronously switched from a position aligned with one of the supporting positions 101 to a position aligned with another adjacent supporting position 101, thereby realizing efficient conveying of the workpiece 20. The transverse driving driver 222 can be configured as a linear driver, such as a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0047] As Figure 1 The first connecting plates 212, the second connecting plate 213, and the lifting driver 221 can be arranged through the bracket 100, and the transverse driving driver 222 can be arranged outside the bracket 100 and pass through the bracket 100 to be connected with the second connecting plate 213. In combination Figure 6 Further, the conveying device 10 further comprises a support 300, and the transverse driving driver 222 can be arranged on the support 300. The support 300 is further provided with a sliding rail 310 extending along the first direction S1, and the first connecting plates 212 are in sliding fit with the sliding rail 310 to improve the stability of the transverse movement of the clamping structure 210 along the first direction S1.

[0048] Regarding the clamping structure 210 provided in each embodiment, the combination of Figure 7 For example, the carrier 100 is provided with a first supporting position 102, a second supporting position 103 and a third supporting position 104 arranged in sequence along the first direction S1, and the clamping structure 210 is provided with a first fixing position 210b and a second fixing position 210c arranged in sequence along the first direction S1. Initially, the first fixing position 210b is located below the first supporting position 102 and is aligned with the first supporting position 102, and the second fixing position 210c is located below the second supporting position 103 and is aligned with the second supporting position 103. During transportation, the lifting driver 221 drives the first connecting plate 212 to rise along the second direction S2, so that the first fixing position 210b clamps the workpiece 20 located in the first supporting position 102, and the second fixing position 210c clamps the workpiece 20 located in the second supporting position 103. After clamping is completed, the horizontal movement driver 222 drives the second connecting plate 213 to move horizontally along the first direction S1, so that the first fixing position 210b carries the workpiece 20 to move to a position aligned with the second supporting position 103, and synchronously, the second fixing position 210c carries the workpiece 20 to move to a position aligned with the third supporting position 104. After alignment, the lifting driver 221 drives the first connecting plate 212 to descend, and the first fixing position 210b places the workpiece 20 in the second supporting position 103, and the second fixing position 210c places the workpiece 20 in the third supporting position 104, thereby achieving single transportation of the workpiece 20. Subsequently, the horizontal movement driver 222 drives the second connecting plate 213 to retreat along the first direction S1, so that the first fixing position 210b returns to a position aligned with the first supporting position 102, and the second fixing position 210c returns to a position aligned with the second supporting position 103, so as to transport the workpieces 20 in the first supporting position 102 and the second supporting position 103 again. In this way, a single cycle movement of the transfer assembly 200 is completed. The transfer assembly 200 repeats the above-mentioned single cycle movement, and can continuously transport the workpieces 20 along the first direction S1, thereby achieving continuous transportation of the workpieces 20. It is easy to understand that after the fixing position 210a clamps the workpiece 20 in the supporting position 101, the lifting driver 221 can further drive the fixing position 210a to rise, so that the workpiece 20 is separated from the carrier 100, thereby reducing friction and wear. Similarly, after the fixing position 210a places the workpiece 20 in the supporting position 101, the lifting driver 221 can further drive the fixing position 210a to descend, so that the workpiece 20 completely exits the fixing position 210a, thereby reducing the probability that the workpiece 20 is accidentally touched and shaken or falls when the clamping structure 210 retreats.

[0049] Please refer to Figure 8In one embodiment, the clamping structure 210 further comprises a sensor 214, and a plurality of sensors 214 are correspondingly arranged at the plurality of fixing positions 210a. The sensor 214 is configured to detect whether there is a workpiece 20 at the corresponding fixing position 210a, so as to obtain whether the clamping structure 210 clamps the workpiece 20 and whether the workpiece 20 is out of the fixing position 210a.

[0050] For further understanding Figure 8 , further, the two limit members 211 forming the same fixing position 210a respectively comprise a first side surface 211c and a second side surface 211d which are away from each other. The limit member 211 is provided with a through hole 211e extending through the first side surface 211c to the second side surface 211d. The sensor 214 comprises a transmitting portion 214a arranged at the first side surface 211c and a receiving portion 214b arranged at the second side surface 211d. The transmitting portion 214a transmits a conductive medium 214c through the fixing position 210a to the receiving portion 214b through the through hole 211e. The conductive medium 214c is configured to trigger the sensor 214 when being blocked. Thus, when the fixing position 210a clamps the workpiece 20, the workpiece 20 will block the conductive medium 214c, and the sensor 214 will be triggered to send a signal. When the workpiece 20 is out of the fixing position 210a, the workpiece 20 will no longer block the conductive medium 214c, and the sensor 214 will be switched from the triggered state to the untriggered state to send a signal. It is easy to understand that the above-mentioned signal is used to indicate whether there is a workpiece 20 at the fixing position 210a. In the embodiment, the first side surface 211c and the second side surface 211d are respectively located in the regions of the two limit members 211 away from each other, and the two limit members 211 are spaced apart to clamp the workpiece 20, i.e., the transmitting portion 214a and the receiving portion 214b are both located in the positions of the fixing position 210a which are not used to clamp the workpiece 20, so as not to block the clamping structure 210 from clamping the workpiece 20. In the embodiment, the limit member 211 is not only used to form the structure for clamping and supporting the workpiece 20, but also provides a mounting space for the sensor 214, so as to obtain whether there is a workpiece 20 at the fixing position 210a.

[0051] For further understanding Figure 9 and Figure 10 In one embodiment, the bracket 100 comprises a first support 110 and a second support 120 which are both extended along the first direction S1, and the first support 110 and the second support 120 are arranged side by side and spaced apart. The supporting positions 101 are extended and distributed on the first support 110 and the second support 120, i.e., the first support 110 and the second support 120 are both used to support the workpiece 20.

[0052] As to the support position 101 and the first support 110 and the second support 120, the support position 101 does not need to drive the workpiece 20 to move, and the support position 101 only needs to meet the requirement of supporting the workpiece 20. The first support 110 and the second support 120 arranged at intervals can support the workpiece 20 from two places, and the support position 101 can be formed by a simple structure. In addition, the first support 110 and the second support 120 arranged at intervals can also provide a space for the clamping structure 210 to pass through. In the embodiment, the clamping structure 210 can pass through the space between the first support 110 and the second support 120 movably, so that the fixed position 210a can clamp the workpiece 20 and drive the workpiece 20 to move horizontally.

[0053] Please refer to Figure 9 and Figure 10 In one embodiment, the first support 110 and the second support 120 are arranged at intervals along a third direction S3, and the third direction S3 is perpendicular to the first direction S1 and the second direction S2. The side of the first support 110 away from the second support 120 is provided with a positioning portion 130. The transport device 10 further comprises a positioning structure 400 arranged on the side of the second support 120 away from the first support 110. The positioning structure 400 is used to push the workpiece 20 along the third direction S3 to a position contacting the positioning portion 130. In the embodiment, the workpiece 20 is pushed by the positioning structure 400 to the position contacting the positioning portion 130 based on the positioning portion 130, so that the workpiece 20 can be positioned to improve the position accuracy of the workpiece 20 during conveying.

[0054] Please refer to Figure 9 and Figure 10 Along the first direction S1, the bracket 100 comprises an upstream end 105 and a downstream end 106, and the workpiece 20 is carried by the transfer assembly 200 from the upstream end 105 to the downstream end 106.

[0055] The positioning portion 130 can be arranged at the support position 101 located at the upstream end 105, and the positioning structure 400 is correspondingly arranged at the upstream end 105. Therefore, the positioning structure 400 in combination with the positioning portion 130 can position the workpiece 20 located at the upstream end 105. Since the third direction S3 is perpendicular to the first direction S1 and the second direction S2, the workpiece 20 will hardly move in the third direction S3 when the workpiece 20 is transported by the transfer assembly 200. Therefore, after the workpiece 20 located at the upstream end 105 is positioned by the positioning structure 400 in combination with the positioning portion 130, the workpiece 20 has a determined position in the third direction S3 during the whole conveying process.

[0056] Please refer to Figure 1 and Figure 10In one embodiment, the positioning structure 400 comprises a stand 410 and a positioning driver 420, the positioning driver 420 is arranged on the stand 410, the stand 410 is used to support the positioning driver 420, so that the positioning driver 420 is substantially at the same height position as the support position 101 along the second direction S2. The positioning driver 420 can be configured as a linear driver, such as a pneumatic cylinder, a hydraulic cylinder or an electric push rod, etc.

[0057] Further, the second direction S2 can be perpendicular to the first direction S1, that is, the first direction S1, the second direction S2 and the third direction S3 are perpendicular to each other.

[0058] Please refer to Figure 11 and Figure 12 In one embodiment, the conveying device 10 further comprises a variable distance assembly (not shown, the same below). The variable distance assembly is connected with at least one of the first support 110 and the second support 120, to drive the first support 110 and the second support 120 to move towards each other and away from each other along the third direction S3. Thus, the first support 110 and the second support 120 are driven by the variable distance assembly to vary the distance in the third direction S3, to adapt to workpieces 20 of different sizes in the third direction S3. Further, the bracket 100 comprises a guide rail 150, and the first support 110 and the second support 120 are respectively in sliding fit with the guide rail 150. The guide rail 150 can guide and limit the variable distance movement of the first support 110 and the second support 120, to improve the stability of the variable distance movement.

[0059] In one embodiment, when the number of the first limiting members 211a and / or the second limiting members 211b is two or more, the plurality of first limiting members 211a and / or the plurality of second limiting members 211b can be arranged in sequence along the third direction S3.

[0060] Please refer to Figure 1 and Figure 9 In one embodiment, the bracket 100 further comprises a plurality of buffer members 140, each buffer member 140 is correspondingly arranged at each support position 101, and the buffer member 140 is used to support the workpiece 20. It is easy to understand that when the fixing member 210a places the workpiece 20 at the support position 101, the buffer member 140 can provide support for the workpiece 20, to reduce the risk of damage to the workpiece 20 by impact. The buffer member 140 can be made of a polymer material with flexibility, such as a silica gel material, a rubber material or a plastic material, etc. Of course, the buffer member 140 can also be made of other materials with flexible support effect, which are not limited here.

[0061] In combination with Figure 1 Further, in one embodiment, at least two buffer members 140 can be arranged at one support position 101, and the at least two buffer members 140 can be respectively arranged at the first support 110 and the second support 120.

[0062] The embodiment of the present application also provides a detection device, which comprises the conveying device 10 as described in each embodiment.

[0063] Since the conveying device 10 has a relatively large structural size in the first direction S1 as a whole, the conveying device 10 is arranged in the first direction S1. Figure 13 In one embodiment, the detection device comprises at least two conveying devices 10 arranged side by side. In this way, the space can be fully utilized and the efficiency of conveying the workpiece 20 can be improved.

[0064] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.
