Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a workpiece clamping carrier. Background Technology

[0002] In automated manufacturing, automated conveyor lines transport workpieces to various workstations, coordinating with the processing equipment at each station to achieve fully automated processing. Typically, to better position and transport products, carrier trays are installed on the conveyor line. Workpieces are loaded onto these trays, which then move along a predetermined path, sequentially passing through each workstation, driven by the conveyor line. The carrier trays play a crucial role in workpiece transport, enabling rapid and accurate transfer and positioning of the workpieces, ensuring the smooth progress of the processing.

[0003] The carrier plate in the related technology includes a carrier plate, with positioning members on one side of the carrier plate in the length direction and width direction, and clamping members on the other side of the carrier plate in the length direction and width direction. The clamping members in the two different directions are driven by independent drive mechanisms. With this structure, the clamping members in different directions need independent drive mechanisms, which makes the structure more complex and makes it impossible to achieve linkage clamping. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide a workpiece clamping carrier.

[0005] To achieve the above objectives, a workpiece clamping carrier according to an embodiment of the present invention includes:

[0006] Carrier plate;

[0007] A contouring stage, which is disposed on the carrier plate and is adapted to hold a predetermined workpiece;

[0008] A synchronous clamping mechanism includes two sets of clamping components disposed on the carrier plate. The two sets of clamping components are respectively located on both sides of the contour table along a first direction and can move towards or away from each other to clamp or release the predetermined workpiece in the first direction.

[0009] A linkage pusher plate is disposed on the carrier plate and is slidable between a first position and a second position along a second direction perpendicular to the first direction; the linkage pusher plate is configured to push the two sets of clamping components to move in opposite directions to release the predetermined workpiece when it moves from the first position to the second position.

[0010] A first elastic element is disposed between the carrier plate and the linkage push plate to provide a first elastic force that forces the linkage push plate to remain in the first position.

[0011] A single-sided positioning and clamping mechanism includes a positioning element and a clamping element. The positioning element is disposed on one side of the carrier plate along the second direction for positioning the predetermined workpiece on one side. The clamping element is disposed on the linkage push plate and is located on the other side of the carrier plate along the second direction for clamping or releasing the predetermined workpiece in the second direction as the linkage push plate moves.

This enables two sets of clamping components in the synchronous clamping mechanism to clamp or release a predetermined workpiece in the first direction. Simultaneously, the clamping components in the single-sided positioning clamping mechanism synchronously clamp or release the predetermined workpiece in the second direction. Thus, with an extremely simple structure, linkage clamping and release in different directions are achieved. The structure is simple, the synchronization is high, and the reliability and stability of the clamping are ensured. Furthermore, the positioning clamping method, which uses a positioning component for single-sided positioning in one direction and two sets of clamping components clamping in opposite directions in the other direction, enables the workpiece to be positioned more accurately and stably on the contour table.

[0071] The workpiece clamping carrier of the present invention will now be described in detail with reference to the accompanying drawings.

[0072] Reference Figures 1 to 7 As shown, the workpiece clamping carrier provided according to an embodiment of the present invention includes a carrier plate 10, a contour stage 20, a synchronous clamping mechanism 30, a linkage push plate 40, a first elastic element 50, a single-sided positioning clamping mechanism, and a drive mechanism 70.

[0073] Specifically, the carrier plate 10 can be a plate of a predetermined shape. When applied to a conveyor line, the carrier plate 10 can be transported by the conveyor line so that the tool clamping carrier is transported to each workstation.

[0074] The contouring stage 20 is disposed on the carrier plate 10 and is adapted to hold a predetermined workpiece. The shape of the contouring stage 20 can be adapted to fit the predetermined workpiece so as to accurately place the predetermined workpiece on the contouring stage 20. For example, if the predetermined workpiece is a mobile phone case, the contouring stage 20 can be designed to fit the shape of the mobile phone case.

[0075] The synchronous clamping mechanism 30 includes two sets of clamping components 301 disposed on the carrier plate 10. The two sets of clamping components 301 are located on opposite sides of the contour stage 20 along a first direction and are capable of moving towards or away from each other to clamp or release the predetermined workpiece in the first direction. That is, one set of clamping components 301 is located on one side of the contour stage 20 along the first direction, and the other set is located on the other side. The two sets of clamping components 301 can move towards each other (moving towards each other) to clamp the predetermined workpiece in the first direction, or they can move away from each other (moving in opposite directions) to release the predetermined workpiece in the first direction. By using two sets of clamping components 301 to move synchronously towards or away from each other to clamp or release the predetermined workpiece, it is ensured that the predetermined workpiece maintains a relatively stable position during the clamping and positioning process.

[0076] A linkage pusher 40 is disposed on the carrier plate 10 and is slidable between a first position and a second position along a second direction perpendicular to the first direction. The linkage pusher 40 is configured to, when moving from the first position to the second position, push the two sets of clamping assemblies 301 to move in opposite directions to release the predetermined workpiece. A first elastic member 50 is disposed between the carrier plate 10 and the linkage pusher 40 to provide a first elastic force that forces the linkage pusher 40 to remain in the first position.

[0077] In other words, the linkage push plate 40 and the two sets of clamping components 301 form a linkage structure, which can drive the two sets of clamping components 301 to move synchronously in opposite directions. The first elastic element 50 acts on the linkage push plate 40, and without any other external force, the first elastic force provided by the first elastic element 50 keeps the linkage push plate 40 in the first position. At this time, the two sets of clamping components 301 clamp the two sides of the predetermined workpiece on the contour table 20. When the linkage push plate 40 moves from the first position to the second position, it can push the two sets of clamping components 301 to move in opposite directions, releasing the predetermined workpiece from the contour table 20. Thus, the clamping and release of the predetermined workpiece by the two sets of clamping components 301 in the first direction is achieved. Furthermore, during the process of the linkage push plate 40 moving to the second position, it needs to overcome the elastic force of the first elastic element 50, and the first elastic element 50 is compressed during this process.

[0078] The single-sided positioning and clamping mechanism includes a positioning element 61 and a clamping element 62. The positioning element 61 is disposed on one side of the carrier plate 10 along the second direction for single-sided positioning of the predetermined workpiece. The clamping element 62 is disposed on the linkage push plate 40 and is located on the other side of the carrier plate 10 along the second direction for clamping or releasing the predetermined workpiece in the second direction as the linkage push plate 40 moves.

[0079] The positioning element 61 is a fixing element fixed to the carrier plate 10, which can be a stop or other structural element that can provide a stopping function. The clamping element 62 is arranged opposite to the positioning element 61 in the second direction of the carrier plate 10. Thus, the area defined between the positioning element 61, the clamping element 62, and the two sets of clamping assemblies 301 is the workpiece placement area, where a predetermined workpiece can be placed. Furthermore, since the clamping element 62 is provided on the linkage push plate 40, when the linkage push plate 40 is in the first position, the clamping element 62 clamps the predetermined workpiece in the second direction. When the linkage push plate 40 moves from the first position to the second position, the clamping element 62 can release the predetermined workpiece by moving with the linkage push plate 40. In this process, the two sets of clamping assemblies 301 move in opposite directions to release the predetermined workpiece in the first direction.

[0080] In other words, when the linkage push plate 40 is in the first position, the two clamping components 301 clamp the predetermined workpiece in the first direction, while the clamping component 62 clamps the predetermined workpiece from the second direction toward the positioning component 61, so that the predetermined workpiece abuts against the positioning component 61 to achieve position positioning, and the clamping component 62 and the two sets of clamping components 301 are used to clamp and fix the predetermined workpiece.

[0081] The drive mechanism 70 is connected to the linkage push plate 40 for driving the linkage push plate 40 from the first position to the second position. Through this drive mechanism 70, the linkage push plate 40 can be driven from the first position to the second position, thereby driving the two sets of clamping components 301 and clamping members 62.

[0082] It should be noted that the driving mechanism 70 applies a driving force to drive the linkage push plate 40 to the second position. As mentioned above, during the process of the linkage push plate 40 moving to the second position, it is necessary to overcome the elastic force of the first elastic element 50, which is compressed during this process. Therefore, when it is necessary to clamp the predetermined workpiece, the driving mechanism 70 removes the driving force, and the first elastic element 50 recovers its deformation and pushes the linkage push plate 40 to quickly return from the second position to the first position, thereby causing the clamping member 62 and the two sets of clamping assemblies 301 to clamp together. That is, the clamping member 62 moves towards the side closer to the positioning member 61 along the second direction, and the two sets of clamping assemblies 301 move towards each other in the direction of approaching each other, thereby realizing the clamping of the predetermined workpiece in the second direction and the first direction.

[0083] When loading a predetermined workpiece, the drive mechanism 70 first drives the linkage push plate 40 to move from the first position to the second position. At this time, the clamping member 62 moves with the linkage push plate 40 in the second direction away from the positioning member 61. The two sets of clamping assemblies 301 move in opposite directions under the push of the linkage push plate 40, thereby keeping the workpiece placement area defined between the positioning member 61, the clamping member 62, and the two sets of clamping assemblies 301 open.

[0084] Next, the predetermined workpiece is placed on the contour stage 20. At this time, the predetermined workpiece is located in the workpiece placement area defined by the positioning member 61, the clamping member 62 and the two sets of clamping components 301. That is, the positioning member 61 and the clamping member 62 are located on both sides of the predetermined workpiece along the second direction, while the two sets of clamping components 301 are located on both sides of the predetermined workpiece along the first direction.

[0085] Finally, the drive mechanism 70 cancels the driving force, and the linkage push plate 40, under the first elastic force provided by the first elastic element 50, quickly returns from the second position to the first position. This causes the clamping element 62 to move along the linkage push plate 40 towards the side closer to the positioning element 61 in the second direction, holding the predetermined workpiece against the positioning element 61 and clamping the predetermined workpiece in the second direction. At the same time, the two sets of clamping assemblies 301 move towards each other under the push of the linkage push plate 40, clamping the predetermined workpiece in the first direction. Thus, the predetermined workpiece can be positioned and clamped simultaneously in the first and second directions.

[0086] In practical applications, after the predetermined workpiece is loaded into the workpiece clamping carrier, the workpiece clamping carrier can be transported sequentially to each processing station using a conveyor line. Then, the processing equipment at the processing station can be used to process the predetermined workpiece, thereby realizing fully automated processing operations.

[0087] According to the workpiece clamping carrier provided in the embodiments of the present invention, a driving mechanism 70 drives the linkage push plate 40 to move between a first position and a second position, realizing that the two sets of clamping components 301 in the synchronous clamping mechanism 30 clamp or release the predetermined workpiece in the first direction. At the same time, the clamping member 62 in the single-sided positioning clamping mechanism simultaneously clamps or releases the predetermined workpiece in the second direction. Thus, with an extremely simple structure, linkage clamping and release in different directions are achieved. The structure is simple, the synchronization is high, and the reliability and stability of clamping are ensured. In addition, the positioning clamping method, which uses the positioning member 61 for single-sided positioning in one direction and the two sets of clamping components 301 clamping in opposite directions in the other direction, can make the position of the workpiece after positioning on the contour table 20 more accurate and stable.

[0088] Reference Figures 2 to 4 and Figure 6 As shown, in one embodiment of the present invention, the linkage push plate 40 forms at least one inclined push surface S40 on each of its two sides along the first direction. The inclined push surface S40 forms an angle with the first direction. The inclined push surface S40 is used to push the clamping assembly 301 to move outward of the workpiece placement area, thereby releasing the predetermined workpiece in the workpiece placement area.

[0089] Each set of clamping components 301 includes at least one clamping component 301, and at least one clamping component 301 corresponds one-to-one with at least one inclined pushing surface S40. Figure 1 In the example, each set of clamping components 301 includes two clamping components 301. Correspondingly, the number of inclined pushing surfaces S40 configured on each side of the linkage push plate 40 in the first direction is also two. The two clamping components 301 are arranged at intervals in the second direction. The predetermined workpiece is clamped by the two clamping components 301 on each side of the first direction. The two clamping components 301 correspond to two clamping points, thereby making the clamping more stable and reliable. It can be understood that the number of clamping components 301 included in each set of clamping components 301 is configured as needed to ensure stable clamping of the predetermined workpiece.

[0090] The clamping assembly 301 includes a clamping member and a second elastic member 302. The clamping member includes a passive portion 3011 and a clamping portion 3012 connected together. Exemplarily, the passive portion 3011 and the clamping portion 3012 are connected to form an L-shaped structure. The passive portion 3011 is slidably disposed on the carrier plate 10 along the first direction and abuts against the inclined pushing surface S40, so as to push the passive portion 3011 to slide outward of the contouring stage 20 through the inclined pushing surface S40. The clamping portion 3012 is located on the outside of the contouring stage 20 and is used to release the predetermined workpiece by following the movement of the passive portion 3011.

[0091] The second elastic element 302 is disposed between the carrier plate 10 and the clamping member, and is used to provide a second elastic force that forces the clamping member to reset towards the inside of the contour stage 20 and clamp the predetermined workpiece.

[0092] When the linkage push plate 40 is in the first position, the passive part 3011 is opposite to the low point of the inclined push surface S40, and under the second elastic force provided by the second elastic member 302, the passive part 3011 elastically abuts against the low point of the inclined push surface S40. At this time, the clamping part 3012 is close to the workpiece placement area, and the workpiece placement area is closed. When the drive mechanism 70 drives the linkage push plate 40 from the first position to the second position, the inclined push surface S40 moves along the second direction, and the inclined push surface S40 gradually moves from the low point to the high point to abut against the passive part 3011. At this time, the inclined push surface S40 generates a pushing force on the passive part 3011, causing the passive part 3011 to move outward of the workpiece placement area along the first direction. In this way, the clamping part 3012 moves synchronously with the passive part 3011 to open the workpiece placement area. Subsequently, when it is necessary to load a workpiece, the predetermined workpiece is placed into the workpiece placement area. Then the driving force of the drive mechanism 70 is removed. At this time, under the first elastic force of the first elastic member 50, the linkage push plate 40 quickly returns to the first position. Then the inclined push surface S40 gradually moves to the low point and is opposite to the passive part 3011. Under the second elastic force provided by the second elastic member 302, the passive part 3011 moves closer to the workpiece placement area, and the clamping part 3012 can clamp the predetermined workpiece.

[0093] In this embodiment, the inclined push surface S40 cooperates with the passive part 3011 on the clamping component 301, and with the help of the second elastic force provided by the second elastic element 302, the clamping component 301 can move synchronously in the first direction in a stable and reliable manner when the linkage push plate 40 switches between the first position and the second position. This realizes the synchronous clamping and release of the two sets of clamping components 301. The structure is simple, the drive is stable and reliable, and the synchronization degree of the two sets of clamping components 301 is high.

[0094] It is understandable that the linkage structure between the linkage push plate 40 and the clamping assembly 301 can also be implemented in other ways. For example, an inclined slide groove can be provided on the linkage push plate 40, and a sliding member that slides with the inclined slide groove can be provided on the passive part 3011. The linkage can also be achieved by utilizing the sliding cooperation between the sliding member and the inclined slide groove. Of course, other linkage structures in the prior art that can convert movement in one direction into movement in another direction perpendicular to it can also be used.

[0095] Reference Figure 3 As shown, in some embodiments of the present invention, the carrier plate 10 is provided with a receiving groove H10, the linkage push plate 40 is slidably disposed in the receiving groove H10 along the second direction, the contour stage 20 covers the receiving groove H10 and hides the linkage push plate 40 in the carrier plate 10.

[0096] In this embodiment, a receiving groove H10 is provided on the carrier plate 10, and the linkage push plate 40 is embedded in the receiving groove H10 and can slide along the second direction. The contouring stage 20 can be provided above the carrier plate 10 and cover the receiving groove H10. In this way, not only can the overall thickness of the workpiece clamping carrier be reduced, but the switching of the linkage push plate 40 between the first position and the second position can also be more reliable and stable.

[0097] Reference Figures 4 to 7 As shown, in one embodiment of the present invention, the passive part 3011 is formed as a strip extending along the first direction, and the end of the passive part 3011 is provided with a first roller 303, the wheel surface of the first roller 303 abuts against the inclined push surface S40 and forms rolling friction.

[0098] In this embodiment, the wheel surface of the first roller 303 abuts against the inclined push surface S40. Since the first roller 303 can rotate around its own axis, when the linkage push plate 40 moves between the first position and the second position along the second direction, the first roller 303 rotates around its own axis on the inclined push surface S40 during the movement. That is, rolling occurs between the inclined push surface S40 and the first roller 303. In this way, the rolling friction reduces the resistance between the two, so that the inclined push surface S40 can push the clamping member to move along the first direction more smoothly and reliably during the movement, ensuring the reliability and stability of the inclined push surface S40 driving the clamping member.

[0099] Reference Figures 4 to 5 As shown, in one embodiment of the present invention, the passive part 3011 is provided with a strip groove H301 extending along the first direction, and a limiting pin 102 is provided on the carrier plate 10, the limiting pin 102 slidingly engaging with the strip groove H301.

[0100] The second elastic element 302 is disposed in the strip groove H301, and one end of the second elastic element 302 abuts against the limiting pin 102, and the other end of the second elastic element 302 abuts against the end wall of the strip groove H301 near the linkage push plate 40.

[0101] In this embodiment, the sliding engagement between the limiting pin 102 and the strip groove H301 allows the limiting pin 102 and the strip groove H301 to slide relative to each other when the clamping member moves along the first direction. This engagement restricts the sliding stroke of the clamping member in the first direction, thus ensuring the reliability of clamping and releasing. Furthermore, the second elastic member 302, located in the strip groove H301, ensures stable and reliable installation, providing a reliable and stable second elastic force to the clamping member, enabling reliable clamping. The second elastic force also provides elastic cushioning, preventing damage to the intended workpiece.

[0102] For example, to facilitate the assembly between the clamping assembly 301 and the carrier plate 10, a fixing block 101 is disposed on the carrier plate 10. A sliding hole H101 extending along a first direction is provided on the fixing block 101, through which the passive part 3011 slides. Simultaneously, a limiting pin 102 is disposed on the fixing block 101 and engages with the strip groove H301 on the passive part 3011. During installation, the clamping component, the second elastic element 302, and the limiting pin 102 can be assembled with the fixing block 101 first, and then the fixing block 101 can be fixed to the carrier plate 10 using screws or other fasteners.

[0103] Reference Figures 3 to 4 and Figure 6 As shown, in some embodiments of the present invention, the drive mechanism 70 includes a lever 701 and a drive block 702. The lever 701 is pivotally mounted on the carrier plate 10, and the drive block 702 is slidably mounted on the carrier plate 10 to push the lever 701 to rotate in a predetermined direction. The lever 701 is configured to push the linkage push plate 40 from the first position to the second position when rotating in the predetermined direction.

[0104] In other words, lever 701 can rotate about an axis on carrier plate 10, while drive block 702 can slide on carrier plate 10, thereby pushing lever 701 to rotate. For example, the middle part of lever 701 is pivotally connected to carrier plate 10 via a pivot, one end of lever 701 is adjacent to or abuts against one end of linkage carrier plate 10, and drive block 702 is adjacent to or abuts against the other end of lever 701. In specific applications, a driver can be configured to push drive block 702 to slide. The driver can be, but is not limited to, a cylinder, linear module, etc. When the driver pushes drive block 702 to move closer to the other end of lever 701, drive block 702 applies a thrust to the other end of lever 701, which causes lever 701 to rotate, and then one end of lever 701 can push linkage push plate 40 to slide from the first position to the second position.

[0105] In this embodiment, the drive mechanism 70, which uses the lever 701 and drive block 702 in combination, can achieve short-stroke drive and ensure reliable drive of the linkage push plate 40 by the lever 701. In addition, its structure is simple and its operation is stable and reliable.

[0106] Reference Figure 6 As shown, in one embodiment of the present invention, a second roller 704 is provided at one end of the lever 701, the second roller 704 abuts against one end of the linkage push plate 40 and forms rolling friction, and a third roller 703 is provided at the other end of the lever 701, the third roller 703 abuts against the drive block 702 and forms rolling friction.

[0107] In this embodiment, one end of the lever 701 forms a rolling friction engagement with one end of the linkage push plate 40 through the second roller 704, and the other end of the lever 701 forms a rolling friction engagement with the drive block 702 through the third roller 703. In this way, the drive block 702 drives the lever 701, and the lever 701 drives the linkage push plate 40 more stably and reliably, preventing possible jamming and other unstable factors.

[0108] It is understandable that the first roller 303, the second roller 704 and the third roller 703 mentioned above can be ordinary rollers or rolling bearings, as long as they can achieve rolling friction with the inclined push surface S40.

[0109] Reference Figure 2 As shown, in one embodiment of the present invention, the contour stage 20 includes a substrate 201 and a workpiece stage 202. The workpiece stage 202 is formed in the center of the substrate 201 and protrudes upward for placing the predetermined workpiece. A reflective lens 203 is provided on the substrate 201 surrounding the peripheral area of ​​the workpiece stage 202.

[0110] In other words, an upwardly protruding workpiece stage 202 is formed on the substrate 201, and the surface of the workpiece stage 202 is the workpiece placement area. The protruding workpiece stage 202 is more conducive to the placement of the workpiece. By setting a reflective lens 203 around the workpiece placement area, the vision camera can take pictures of the predetermined workpiece during subsequent processing. When acquiring the workpiece image, the light emitted by the reflective lens 203 can be used to improve the clarity of the image, thereby improving the quality of subsequent processing.

[0111] In some embodiments of the present invention, the carrier plate 10 is provided with an electronic tag for tracking the position of the workpiece clamping carrier. The electronic tag may contain information such as the number of the workpiece clamping carrier. Thus, throughout the entire automated machining process, the information of the electronic tag can be read by a card reader at different machining stations, thereby enabling tracking and monitoring of the entire machining process and facilitating the orderly management of the machining process.

[0112] Reference Figure 2 As shown, in some embodiments of the present invention, the bottom of the carrier plate 10 is provided with a guide rail 103 for cooperating with the conveyor line to transport the workpiece clamping carrier via the conveyor line. In specific applications, the conveyor line has a guiding structure that cooperates with the guide rail 103, such as guide wheels, guide grooves, etc., so that the carrier plate 10 can move stably and reliably. Thus, when the workpiece clamping carrier is applied to automated processing production, it can be automatically transported with the conveyor line, and the workpiece clamping carrier can be sequentially transported to each workstation to complete orderly processing with the processing equipment, thereby improving production efficiency.
