Description

Technical Field

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

[0002] In automated manufacturing, workpieces are transported to various workstations using automated conveyor lines, which work in conjunction with the processing equipment at each workstation to achieve fully automated processing. Typically, to better position and transport the products, carrier trays are installed on the conveyor line. The workpieces to be processed are loaded onto the carrier trays, which then move along a predetermined path, sequentially passing through each workstation, driven by the conveyor line.

[0003] For some electronic products, it is often necessary to assemble various small components onto the main body. For example, in the manufacturing of mobile phones, components such as operation buttons, cameras, and lights need to be assembled onto the main control board. To transport these small components, various clamping devices are required on a carrier tray to hold and secure them. However, in related technologies, these clamping devices perform clamping actions in different directions, typically requiring separate drive mechanisms. This results in a complex structure and poor reliability and stability. Summary of the Invention

The first workpiece hole and the second workpiece hole are arranged opposite to each other in a first direction, and the third workpiece hole and the fourth workpiece hole are arranged opposite to each other in a second direction.

[0026] The single-power multi-directional linkage workpiece clamping carrier of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] Reference Figures 1 to 5As shown, the single-power multi-directional linkage workpiece clamping carrier provided according to an embodiment of the present invention includes a base plate 10, a carrier plate 20, two first elastic clamping assemblies 30, a second elastic clamping assembly 40, a third elastic clamping assembly 50, a linkage frame 60, and a first elastic element 70.

[0028] Specifically, the base plate 10 can be a plate-shaped component. When applied to a conveyor line, the base plate 10 can be transported by the conveyor line, so that the tool clamping carrier can be transported to various workstations.

[0029] A carrier plate 20 is disposed on the base plate 10. The carrier plate 20 has a first workpiece hole H201, a second workpiece hole H202, a third workpiece hole H203, and a fourth workpiece hole H204. The first workpiece hole H201 and the second workpiece hole H202 are arranged opposite each other in a first direction, and the third workpiece hole H203 and the fourth workpiece hole H204 are arranged opposite each other in a second direction. The first direction is perpendicular to the second direction. These workpiece holes are used to load various small-sized workpieces. For example, in the manufacturing of some electronic products, small workpieces such as cameras, buttons, and lights are assembled onto the main control board; these workpiece holes can be used to load such small workpieces.

[0030] Two first elastic clamping components 30 are disposed on the base plate 10 and respectively located in the first workpiece hole H201 and the second workpiece hole H202, and are movable along a first direction. That is, one of the two first elastic clamping components 30 is located in the first workpiece hole H201 for clamping or releasing the workpiece in the first workpiece hole H201. The other of the two first elastic clamping components 30 is located in the second workpiece hole H202 for clamping or releasing the workpiece in the second workpiece hole H202. It can be understood that the first elastic clamping component 30 being located in the first workpiece hole H201 / second workpiece hole H202 can mean that its portion is located within either the first workpiece hole H201 or the second workpiece hole H202.

[0031] The second elastic clamping assembly 40 is disposed on the base plate 10 and located in the third workpiece hole H203, and is movable in the second direction. The second elastic clamping assembly 40 is used to clamp or release the workpiece in the third workpiece hole H203. The third elastic clamping assembly 50 is disposed on the base plate 10 and located in the fourth workpiece hole H204, and is movable in the second direction. The third elastic clamping assembly 50 is used to clamp or release the workpiece in the fourth workpiece hole H204. Similarly, the second elastic clamping assembly 40 being located in the third workpiece hole H203 can mean that its portion is located within the third workpiece hole H203, and the third elastic clamping assembly 50 being located in the fourth workpiece hole H204 can mean that its portion is located within the fourth workpiece hole H204.

[0032] The linkage frame 60 is disposed on the base plate 10 and located between the second elastic clamping assembly 40 and the third elastic clamping assembly 50. The linkage frame 60 is configured to move synchronously with the second elastic clamping assembly 40 and the third elastic clamping assembly 50 from a first position to a second position along the second direction, so that the second elastic clamping assembly 40 and the third elastic clamping assembly 50 release the workpieces in the third workpiece hole H203 and the fourth workpiece hole H204 respectively, and release the workpieces in the first workpiece hole H201 and the second workpiece hole H202 by linking the two first elastic clamping assemblies 30 to move along the first direction through the linkage frame 60.

[0033] In other words, on the one hand, the linkage frame 60 can slide synchronously along the second direction with the second elastic clamping component 40 and the third elastic clamping component 50, and when it slides from the first position to the second position, the second elastic clamping component 40 and the third elastic clamping component 50 move synchronously to release the workpieces in the third workpiece hole H203 and the fourth workpiece hole H204. On the other hand, during the process of sliding from the first position to the second position, the linkage frame 60 can be linked with the two first elastic clamping components 30. That is, when the linkage frame 60 moves from the second direction to the second position, the linkage frame 60 can push the two first elastic clamping components 30 to move along the first direction, thereby releasing the workpieces in the first workpiece hole H201 and the second workpiece hole H202.

[0034] For example, in order to achieve synchronous movement of the linkage frame 60 with the second elastic clamping component 40 and the third elastic clamping component 50, the linkage frame 60 can be fixed relative to the second elastic clamping component 40 and the third elastic clamping component 50, or the three can be abutted against each other in the second direction, and a thrust can be applied along the second direction to push the three to move synchronously. A linkage structure is usually formed between the linkage frame 60 and the two first elastic clamping components 30, which enables the two first elastic clamping components 30 to move in the first direction when the linkage frame 60 moves.

[0035] The first elastic element 70 is configured to provide a first elastic force that forces the linkage frame 60, the second elastic clamping assembly 40, and the third elastic clamping assembly 50 to return synchronously from the second position to the first position, so that the second elastic clamping assembly 40 and the third elastic clamping assembly 50 clamp the workpieces in the third workpiece hole H203 and the fourth workpiece hole H204 respectively, and the linkage frame 60 links the two first elastic clamping assemblies 30 to reset along the first direction to clamp the workpieces in the first workpiece hole H201 and the second workpiece hole H202.

[0036] In other words, without any external force, the first elastic force provided by the first elastic element 70 keeps the linkage frame 60, the second elastic clamping assembly 40, and the third elastic clamping assembly 50 in the first position. At this time, the second elastic clamping assembly 40 and the third elastic clamping assembly 50 maintain elastic clamping of the workpieces in the third workpiece hole H203 and the fourth workpiece hole H204. Simultaneously, the two first elastic clamping assemblies 30 also maintain elastic clamping of the workpieces in the first workpiece hole H201 and the second workpiece hole H202. However, when a thrust is applied to move the linkage frame 60, the second elastic clamping assembly 40, and the third elastic clamping assembly 50 synchronously from the first position to the second position, the first elastic force of the first elastic element 70 needs to be overcome, at which point the first elastic element 70 is compressed. When the thrust is removed, the first elastic element 70 elastically resets, and the first elastic force pushes the linkage frame 60, the second elastic clamping component 40 and the third elastic clamping component 50 to quickly return from the second position to the first position, thereby restoring the clamping state of the two first elastic clamping components 30, the second elastic clamping component 40 and the third elastic clamping component 50.

[0037] It should be noted that, in specific applications, a drive device can be configured to drive the linkage frame 60 and the second elastic clamping assembly 40 and the third elastic clamping assembly 50 to move synchronously from the first position to the second position. This drive device can be, but is not limited to, a cylinder, an electric actuator, a linear module, etc. For ease of connection, since the second elastic clamping assembly 40 or the third elastic clamping assembly 50 is located on both sides of the base plate 10 in the second direction, the output end of the drive device can be connected to the second elastic clamping assembly 40 or the third elastic clamping assembly 50 to apply thrust, thereby pushing the linkage frame 60 and the second elastic clamping assembly 40 and the third elastic clamping assembly 50 to move synchronously in the second direction.

[0038] When loading workpieces, the drive device first drives the linkage frame 60, the second elastic clamping assembly 40, and the third elastic clamping assembly 50 to move synchronously from the first position to the second position, so that the first workpiece hole H201, the second workpiece hole H202, the third workpiece hole H203, and the fourth workpiece hole H204 are in the open state. Next, each workpiece is placed into the first workpiece hole H201, the second workpiece hole H202, the third workpiece hole H203, and the fourth workpiece hole H204, respectively. Then, the drive device removes the thrust. At this time, the elastic reset action of the first elastic element 70 causes the linkage frame 60, the second elastic clamping assembly 40, and the third elastic clamping assembly 50 to synchronously and quickly reset to the first position. At this point, the two first elastic clamping assemblies 30 can clamp the workpieces in the first workpiece hole H201 and the second workpiece hole H202, while the second elastic clamping assembly and the third elastic clamping assembly 50 can clamp the workpieces in the third workpiece hole H203 and the fourth workpiece hole H204. Finally, the conveyor line transports the workpiece clamping carrier to each processing station in sequence for processing.

[0039] According to the embodiments of the present invention, the single-power multi-directional linkage workpiece clamping carrier has two first elastic clamping components 30 arranged in the first direction, and a second elastic clamping component 40 and a third elastic clamping component 50 arranged in the second direction. A linkage frame 60 is arranged between the second elastic clamping component 40 and the third elastic clamping component 50. The linkage frame 60 is used to realize the linkage clamping or release of the workpiece by the first elastic clamping component 30, the second elastic clamping component 40 and the third elastic clamping component 50, achieving the effect of single-drive multi-directional linkage clamping. This not only makes the structure simpler and the cost lower, but also enables the workpiece clamping carrier to have more reliable and stable clamping and positioning performance, which is beneficial to automated processing and improves production efficiency.

[0040] Reference Figures 1 to 2 As shown, in one embodiment of the present invention, a workpiece adsorption area P20 is provided on the carrier plate 20, and the workpiece adsorption area P20 is provided with negative pressure adsorption holes H20. The first workpiece hole H201 and the second workpiece hole H202 are located on both sides of the workpiece adsorption area along the first direction, and the third workpiece hole H203 and the fourth workpiece hole H204 are located on both sides of the workpiece adsorption area P20 along the second direction.

[0041] In other words, in this embodiment, a workpiece adsorption area P20 is also provided in the middle of the carrier plate 20. This workpiece adsorption area P20 is equipped with negative pressure adsorption holes H20, and the interior of the carrier plate 20 is provided with a negative pressure channel communicating with the negative pressure adsorption holes H20. In application, this negative pressure channel is connected to a negative pressure device. By drawing a vacuum through the negative pressure device, a negative pressure adsorption state is formed between the negative pressure channel and each negative pressure adsorption hole H20. Thus, when a sheet-like workpiece is placed in the workpiece adsorption area P20, the sheet-like workpiece can be adsorbed and fixed in the workpiece adsorption area P20 by utilizing the negative pressure adsorption effect, thereby realizing the loading of the sheet-like workpiece and improving the loading capacity and versatility of the workpiece clamping carrier.

[0042] Reference Figures 2 to 3 As shown, in some embodiments of the present invention, the base plate 10 is provided with a groove, the second elastic clamping assembly 40, the linkage frame 60 and the third elastic clamping assembly 50 are slidably disposed in the groove along the second direction, the carrier plate 20 covers the groove and hides the linkage frame 60 in the base plate 10.

[0043] In this embodiment, a groove is provided on the base plate 10, and the second elastic clamping assembly 40, the linkage frame 60, and the third elastic clamping assembly 50 are embedded in the groove and can slide within it. The carrier plate 20 is located above the base plate 10 and covers the groove. In this way, not only can the overall thickness of the workpiece clamping carrier be reduced, but the switching between the linkage frame 60, the second elastic clamping assembly 40, and the third elastic clamping assembly 50 between the first and second positions can also be made more stable and reliable.

[0044] Reference Figures 2 to 5 As shown, in one embodiment of the present invention, the linkage frame 60 is provided with actuating portions 601 on both sides along the first direction. An inclined pushing surface S60 is formed on each actuating portion 601, and the inclined pushing surface S60 forms an angle with the first direction. The inclined pushing surface S60 is used to push the first elastic clamping assembly 30 to move along the first direction, thereby releasing the workpiece from the first workpiece hole H201 or the second workpiece hole H202.

[0045] The first elastic clamping assembly 30 includes a first clamping member 301 and a second elastic member 302. The first clamping member 301 includes a passive part 3011 and a clamping part 3012 connected together. The passive part 3011 is slidably disposed on the base plate 10 along the first direction and abuts against the inclined pushing surface S60, so as to push the passive part 3011 to slide through the inclined pushing surface S60. For example, the passive part 3011 and the clamping part 3012 are connected to form an L-shaped structure. The clamping part 3012 is located in the first workpiece hole H201 or the second workpiece hole H202, and is used to release the workpiece in the first workpiece hole H201 or the second workpiece hole H202 by following the movement of the passive part 3011.

[0046] The second elastic member 302 is disposed between the base plate 10 and the first clamping member, and is used to provide a second elastic force to force the first clamping member to reset and clamp the workpiece in the first workpiece hole H201 or the second workpiece hole H202.

[0047] When the drive device drives the linkage frame 60, the second elastic clamping assembly 40, and the third elastic clamping assembly 50 from the first position to the second position, the inclined push surface S60 moves along the second direction, generating a pushing force on the passive part 3011, causing the passive part 3011 to move along the first direction. Thus, the clamping part 3012 moves synchronously with the passive part 3011, releasing the workpieces in the third workpiece hole H203 and the fourth workpiece hole H204. When it is necessary to clamp the workpiece, the drive device removes the pushing force. Under the first elastic force of the first elastic element 70, the linkage frame 60, the second elastic clamping assembly 40, and the third elastic clamping assembly 50 quickly return to the first position. Then, the inclined push surface S60 moves in the opposite direction, and under the second elastic force provided by the second elastic element 302, the passive part 3011 resets, and the clamping part 3012 clamps the workpiece.

[0048] In this embodiment, the inclined push surface S60 cooperates with the passive part 3011 on the first elastic clamping component 30, and with the help of the second elastic force provided by the second elastic element 302, the linkage frame 60 can be linked with the first elastic clamping component 30 when switching between the first position and the second position, so that the first elastic clamping component 30 can move synchronously and reliably along the first direction, realizing the clamping and releasing of the first elastic clamping component 30. Its structure is simple, the drive is stable and reliable, and the synchronization of the first elastic clamping component 30 is high.

[0049] It is understandable that the linkage structure between the linkage frame 60 and the first elastic clamping assembly 30 can also be implemented in other ways. For example, an inclined slide groove can be provided on the linkage frame 60, 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.

[0050] Reference Figure 3 As shown, in one embodiment of the present invention, the actuating portions 601 of the linkage frame 60 are symmetrically arranged on both sides of the first direction, so that the linkage frame 60 pushes the two first elastic clamping components to move toward or in opposite directions in the first direction.

[0051] In this embodiment, the actuating parts 601 on both sides of the linkage frame 60 are symmetrically arranged. Correspondingly, the inclined pushing surfaces S60 on the two opposing actuating parts 601 are also symmetrically arranged. Thus, during the movement of the linkage frame 60 to the second position, the two first elastic clamping components 30 move synchronously in opposite directions, thereby releasing the workpieces in the first workpiece hole H201 and the second workpiece hole H202. This synchronous reverse movement method can meet the requirement of the symmetrical arrangement of the first workpiece hole H201 and the second workpiece hole H202, and at the same time, it can also achieve higher synchronization and achieve a stable and reliable synchronous clamping effect.

[0052] Reference Figures 3 to 4 As shown, in one embodiment of the present invention, the passive part 3011 is formed as a strip extending along the first direction, and a roller 303 is provided at the end of the passive part 3011. The wheel surface of the roller 303 abuts against the inclined pushing surface S60 and forms rolling friction.

[0053] In this embodiment, the roller 303 abuts against the inclined push surface S60. Since the roller 303 can rotate around its own axis, when the linkage frame 60 moves between the first position and the second position along the second direction, the roller 303 rotates around its own axis on the inclined push surface S60 during the movement. That is, rolling occurs between the inclined push surface S60 and the roller 303. This rolling friction reduces the resistance between the two, allowing the inclined push surface S60 to push the first clamping member 301 to move along the first direction more smoothly and reliably during the movement, ensuring the reliability and stability of the inclined push surface S60's drive on the first clamping member 301.

[0054] Reference Figure 3 As shown, in one embodiment of the present invention, the groove includes a first clamping groove H101, a second clamping groove H102, and a support groove H103 connected between the first clamping groove H101 and the second clamping groove H102. Exemplarily, the support groove H103 is connected to form an "I"-shaped groove between the first clamping groove H101 and the second clamping groove H102.

[0055] The second elastic clamping assembly 40 includes a first sliding seat 401, a second clamping member 402, and a third elastic member. The first sliding seat 401 is slidably disposed in the first clamping groove H101 along the second direction. The second clamping member 402 is slidably disposed on the first sliding seat 401 along the second direction and is partially located in the third workpiece hole H203. The third elastic member is disposed between the first sliding seat 401 and the second clamping member 402 to provide a third elastic force that forces the second clamping member 402 to clamp the workpiece in the third workpiece hole H203.

[0056] The third elastic clamping assembly 50 includes a second sliding seat 501, a third clamping member 502, and a fourth elastic member. The second sliding seat 501 is slidably disposed in the second clamping groove H102 along the second direction. The third clamping member 502 is slidably disposed on the second sliding seat 501 along the second direction and is partially located in the fourth workpiece hole H204. The fourth elastic member is disposed between the second sliding seat 501 and the third clamping member 502 to provide a fourth elastic force that forces the third clamping member 502 to clamp the workpiece in the fourth workpiece hole H204.

[0057] The linkage frame 60 is slidably disposed in the bracket groove H103, and one end of the linkage frame 60 abuts against the first sliding seat 401, and the other end of the linkage frame 60 abuts against the second sliding seat 501.

[0058] In other words, the first sliding seat 401 is slidable in the first clamping groove H101, while the second clamping member 402 is mounted on and slidable on the first sliding seat 401. The first elastic member 70 provides a third elastic force to the second clamping member 402, enabling the second clamping member 402 to elastically clamp the workpiece in the third workpiece hole H203. Correspondingly, the second sliding seat 501 is slidable in the second clamping groove H102, while the third clamping member 502 is mounted on and slidable on the second sliding seat 501. The second elastic member 302 provides a fourth elastic force to the third clamping member 502, enabling the third clamping member 502 to elastically clamp the workpiece in the fourth workpiece hole H204. Thus, the elastic clamping action provided by the second clamping member 402 and the third clamping member 502 can protect the clamped workpiece, preventing clamping damage. At the same time, this elastic clamping also improves the reliability of workpiece clamping.

[0059] Furthermore, both ends of the linkage frame 60 abut against the first sliding seat 401 and the second sliding seat 501, respectively. In specific applications, the output end of the drive device can be connected to either the first sliding seat 401 or the second sliding seat 501. When the drive device applies a thrust, the first sliding seat 401 or the second sliding seat 501 slides. Since both ends of the linkage frame 60 abut against the first sliding seat 401 and the second sliding seat 501, the thrust can be transmitted between the linkage frame 60, the first sliding seat 401, and the second sliding seat 501, thereby enabling the linkage frame 60, the first elastic clamping assembly 30, and the second elastic clamping assembly 40 to slide synchronously in the first direction. This abutting arrangement ensures that the linkage frame 60, the first sliding seat 401, and the second sliding seat 501 can move reliably and synchronously. In addition, the components are independent of each other, facilitating manufacturing and assembly.

[0060] Advantageously, the first elastic element 70 is disposed between the base plate 10 and the first sliding seat 401 or the second sliding seat 501. In this way, the first elastic element 70 can provide a reliable and stable first elastic force, thereby ensuring the ability of the linkage frame 60, the second elastic clamping assembly 40 and the third elastic clamping assembly 50 to reset to the first position.

[0061] Reference Figure 5 As shown, in one embodiment of the present invention, a fixed seat 101 is provided on the base plate 10, and a sliding groove is provided on the fixed seat 101, and the passive part 3011 slides in cooperation with the sliding groove.

[0062] The passive part 3011 has a strip-shaped groove extending along the first direction, and a limiting pin 102 is provided on the fixed base 101. The limiting pin 102 is slidably engaged with the strip-shaped groove. The second elastic member 302 is disposed in the strip-shaped groove and abuts against the limiting pin 102 and the inner wall of the strip-shaped groove.

[0063] In this embodiment, the sliding engagement between the limiting pin 102 and the strip groove allows the limiting pin 102 and the strip groove to slide relative to each other when the first clamping member 301 moves along the first direction. This engagement between the strip groove and the limiting pin 102 restricts the sliding stroke of the first clamping member 301 in the first direction, thus ensuring the reliability of clamping and releasing. Furthermore, the second elastic member 302, located in the strip groove, ensures stable and reliable installation, providing a reliable and stable second elastic force to the first clamping member 301. This allows it to maintain reliable clamping and elastic buffering, preventing damage to the workpiece.

[0064] It is understandable that the second elastic clamping assembly 40 and the third elastic clamping assembly 50 can adopt a similar structure to the first elastic clamping assembly 30 to install the third elastic element and the fourth elastic element, that is, to adopt a groove and pin mating structure with the third elastic element / fourth elastic element, which will not be elaborated here.

[0065] Preferably, the second clamping member 402 and the third clamping member 502 are configured with different clamping structures to clamp different types of workpieces, thus meeting the loading needs of various workpieces in different product processing.
