Description

Technical Field

[0001] This invention relates to assembly tools for electronic products, specifically assembly tools for lids. Background Technology

[0002] An assembled watch cover, or an assembled camera lens cover, includes a ring-shaped component that is assembled with other components to form the watch cover / lens cover. During assembly, the ring-shaped component is positioned in a ring-shaped component carrier, while the other components are positioned in other component carriers. The operator needs to remove the ring-shaped component from the ring-shaped component carrier, transfer it to the other component carriers, and assemble the ring-shaped component with the other components by clamping. Summary of the Invention

[0003] The technical problem solved by this invention is: how to conveniently assemble a ring-shaped part with other parts to form a cover for an electronic product.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic pressure holding and manual material clamping mechanism, comprising a cover plate assembly and a gripper module. The cover plate assembly includes a cover plate with a gripper module receiving cavity in the middle, hooks on both sides of the cover plate, and a limiting plate fixed to the top of the cover plate. A limiting edge is provided on the side wall of the gripper module receiving cavity. The gripper module includes a floating pressure block assembly and an inner support gripper assembly disposed on the floating pressure block assembly. The floating pressure block assembly is provided with a limiting step and is movably fitted in the gripper module receiving cavity. A vertical compression spring is provided between the floating pressure block assembly and the limiting plate. Under the action of the vertical compression spring, the limiting step abuts against the limiting edge. The gripper part of the inner support gripper assembly extends downward to the bottom of the cover plate, and the driving part of the inner support gripper assembly protrudes upward from the cover plate.

[0005] The annular part is positioned in an annular part carrier, while other parts (other parts assembled with the annular part to form the cover) are positioned in other part carriers. The operator needs to remove the annular part from the annular part carrier and transfer it to the other part carrier. The operator engages the mechanism with the annular part carrier; specifically, the hooks on both sides of the cover plate engage with the steps on both sides of the annular part carrier, and the gripper portion of the inner support gripper assembly is located within the annular part. Then, the operator actuates the drive portion of the inner support gripper assembly, causing the gripper portion of the inner support gripper assembly to open and tighten against the inner wall of the annular part, thus clamping the annular part. Afterward, the operator disengages the hooks from the annular part carrier, the mechanism disengages from the annular part carrier, and the clamped annular part is moved to the other part carrier. The operator then presses down on the mechanism, pressing it firmly onto the other part carrier, and the hooks engage with the steps on the sides of the other part carrier. Specifically, the cover assembly engages with other parts carriers, while the floating pressure block assembly, under the elastic force of the vertical compression spring, presses against the annular part, clamping it onto the parts in the other parts carriers. This assembly, together with the annular part, forms a cover (watch cover / camera lens cover), and is maintained by the pressure from the floating pressure block assembly. After assembly and pressure maintenance, the operator activates the drive mechanism of the inner support gripper assembly, causing the gripper to reset and releasing the annular part. The operator then disengages the hook from the other parts carriers, detaching the mechanism from the assembled cover, which remains in the other parts carriers.

[0006] This device can assist operators in manually gripping materials, assembling them, and simultaneously maintaining pressure, making the lid assembly convenient and cost-effective.

[0007] The hook is pivotally connected to the hook shaft, which is mounted on the cover plate. A hook spring is provided between the top plate of the hook and the cover plate. The hook spring causes the hook to have a tendency to rotate around the hook shaft, thereby enabling the hook to effectively engage with the step on the side of the annular part carrier or other part carrier.

[0008] The floating pressure block assembly includes a floating pressure block, a cam support fixed to the top of the floating pressure block, and a gripper guide plate fixed to the bottom of the floating pressure block. The driving part of the internal support gripper assembly includes a cam mounted on the cam support and a driving rod movably engaged in the floating pressure block. The top of the driving rod movably engages with the cam, and the bottom of the driving rod movably engages with the gripper portion of the internal support gripper assembly. The gripper portion movably engages in the gripper guide plate. The limiting step is provided on the floating pressure block. The limiting step abuts against the limiting edge to limit the descent of the floating pressure block assembly, while the limiting plate limits the rise of the floating pressure block assembly.

[0009] When retrieving the annular part, the cover assembly of this mechanism engages with the annular part carrier. The gripper portion of the internal support gripper assembly is located within the annular part. The operator activates the cam, which releases the drive rod. The drive rod rises, releasing the gripper portion, causing it to open and clamp against the inner wall of the annular part, holding the part. During assembly, the cover assembly engages with other part carriers. A floating pressure block presses the annular part, held by the gripper portion, against other parts in the other part carriers, maintaining pressure. After pressure maintenance, the operator resets the cam, which drives the drive rod to descend and reset. The drive rod then drives the gripper portion to retract and reset, releasing the annular part. After the operator disengages the hook from the other part carriers, this mechanism detaches from the other part carriers and the assembled cover.

[0010] The cam is pivotally connected to a camshaft, which is mounted on a cam support. The cam has a finger-operated portion with an arc-shaped structure on its top surface and limiting protrusions on both sides. These limiting protrusions abut against the upper surface of the cam support. The operator touches the arc-shaped structure with their finger, driving the cam to rotate forward until one limiting protrusion abuts against the upper surface of the cam support, causing the gripper to clamp the annular part. The cam rotates in the reverse direction until the other limiting protrusion abuts against the upper surface of the cam support, at which point the drive rod descends to its original position, the gripper retracts, and the annular part is released. This design allows for convenient cam operation and controllable cam rotation angle.

[0011] The bottom of the drive rod is provided with a V-shaped drive groove. The gripper part includes a pair of grippers and a gripper spring disposed between the pair of grippers. The grippers have wedge-shaped portions, and the wedge-shaped portions of the pair of grippers move towards each other and engage in the V-shaped drive groove. When the drive rod descends, the V-shaped drive groove drives the pair of grippers to move closer together, releasing the annular part. When the cam no longer presses against the drive rod, driven by the gripper spring, the pair of grippers move away from each other. The wedge-shaped portions of the pair of grippers drive the drive rod to rise, and the pair of grippers, now far apart, open up and clamp against the inner wall of the annular part, holding the annular part. This invention utilizes the elastic force of the gripper spring to open the pair of grippers and clamp the annular part, rather than using the V-shaped drive groove to drive the wedge block to open the pair of grippers. This design facilitates stable clamping of the annular part by the pair of grippers and avoids the free movement of the drive rod during clamping, which could cause the pair of grippers to loosen the annular part.

[0012] The gripper guide plate has a gripper guide groove, and a pair of grippers engage in the gripper guide groove. The end of the gripper away from the wedge-shaped part has a bent chuck. The gripper protrudes laterally from the gripper guide plate and can abut against the outer edge of the gripper guide plate to limit the range of gripper retraction. Attached Figure Description

[0032] Combination Figure 1 , Figure 7 , Figure 12 An automatic pressure-holding and manual material-clamping mechanism includes a cover plate assembly and a gripper module. The cover plate assembly includes a cover plate 10 with a gripper module receiving cavity in the middle, hooks 11 on both sides of the cover plate, and a limiting plate 20 fixed to the top of the cover plate. A limiting edge 12 is provided on the side wall of the gripper module receiving cavity. The gripper module 30 includes a floating pressure block assembly and an inner support gripper assembly provided on the floating pressure block assembly. The floating pressure block assembly is provided with a limiting step 311. The floating pressure block assembly is movably fitted in the gripper module receiving cavity. A vertical compression spring 34 is provided between the floating pressure block assembly and the limiting plate. Under the action of the vertical compression spring, the limiting step 311 abuts against the limiting edge 12. The gripper part of the inner support gripper assembly extends downward to the bottom of the cover plate, and the driving part of the inner support gripper assembly protrudes upward from the cover plate 10.

[0033] The annular part is positioned in an annular part carrier, while other parts constituting the cover are positioned in other part carriers. The operator needs to remove the annular part from the annular part carrier and transfer it to the other part carrier. The operator engages the mechanism with the annular part carrier; specifically, the hooks 11 on both sides of the cover plate 10 engage with the steps on both sides of the annular part carrier, and the gripper portion of the inner support gripper assembly is located within the annular part. Then, the operator actuates the drive portion of the inner support gripper assembly, causing the gripper portion of the inner support gripper assembly to open and tighten against the inner wall of the annular part, thus clamping the annular part. Afterward, the operator disengages the hooks 11 from the annular part carrier, the mechanism disengages from the annular part carrier, and the clamped annular part is moved to the other part carrier. The operator then presses down on the mechanism, pressing it firmly onto the other part carrier, and the hooks 11 engage with the steps on the sides of the other part carriers. Specifically, the cover assembly engages with other parts carriers, while the floating pressure block assembly, under the elastic force of the vertical compression spring 34, presses against the annular part, clamping it onto the parts in the other parts carriers to assemble the cover, and the floating pressure block assembly maintains pressure. After assembly and pressure maintenance, the operator activates the drive part of the inner support gripper assembly to reset the gripper part, releasing the annular part. Then, the operator disengages the hook 11 from the other parts carriers, and the mechanism detaches from the assembled cover, which remains in the other parts carriers.

[0034] like Figure 7 Hook 11 is pivotally connected to hook shaft 112, which is mounted on cover plate 10. Hook spring 113 is provided between hook top plate 111 and cover plate. Hook spring 113 causes hook 11 to have a tendency to rotate around hook shaft 112, thereby enabling hook 11 to be effectively engaged on the step on the side of the annular part carrier or other part carrier.

[0035] like Figure 12 The floating pressure block assembly includes a floating pressure block 31, a cam support 32 fixed to the top of the floating pressure block, and a gripper guide plate 33 fixed to the bottom of the floating pressure block. The driving part of the internal support gripper assembly includes a cam 40 mounted on the cam support and a driving rod 41 movably engaged in the floating pressure block. The top of the driving rod movably engages with the cam, and the bottom of the driving rod movably engages with the gripper part of the internal support gripper assembly. The gripper part movably engages in the gripper guide plate. The limiting step 311 is provided on the floating pressure block 31. The limiting step 311 abuts against the limiting edge 12 to limit the descent of the floating pressure block assembly, while the limiting plate 20 limits the rise of the floating pressure block assembly.

[0036] When acquiring the annular part, the cover assembly of this mechanism engages with the annular part carrier. The gripper portion of the internal support gripper assembly is located within the annular part. The operator activates cam 40, releasing drive rod 41. The drive rod rises, releasing the gripper portion, causing it to open and clamp against the inner wall of the annular part, holding the part. During assembly, the cover assembly engages with other part carriers. Floating pressure block 31 presses the annular part held by the gripper portion against other parts in other part carriers, maintaining pressure. After pressure maintenance, the operator resets cam 40, driving drive rod 41 to descend and reset. The drive rod then retracts the gripper portion, releasing the annular part. After the operator detaches hook 11 from other part carriers, this mechanism disengages from other part carriers and the assembled cover.

[0037] like Figure 12 , Figure 13 The cam 40 is pivotally connected to the camshaft, which is mounted on the support 321 of the cam support 32. The cam has a finger operating part 401, with an arc-shaped structure on its top surface and limiting protrusions 402 on both sides. The limiting protrusions can abut against the upper surface of the cam support. When the operator touches the arc-shaped structure with their finger, the cam 40 is driven to rotate forward until one of the limiting protrusions 402 abuts against the upper surface of the cam support 32, driving the gripper to clamp the annular part. The cam 40 rotates in the opposite direction until the other limiting protrusion 402 abuts against the upper surface of the cam support 32, at which point the drive rod 41 descends to reset, the gripper closes, and the annular part is released.

[0038] The bottom of the drive rod 41 is provided with a V-shaped drive groove 411. The gripper portion includes a pair of grippers 42 and a gripper spring 43 disposed between the pair of grippers. The grippers are provided with wedge-shaped portions 421. The wedge-shaped portions of the pair of grippers approach each other and engage in the V-shaped drive groove. When the drive rod 41 descends, the V-shaped drive groove 411 drives the pair of grippers 42 to approach each other, releasing the annular part. When the cam 40 no longer presses the drive rod 41, under the drive of the gripper spring 43, the pair of grippers move away from each other. The wedge-shaped portions 421 of the pair of grippers drive the drive rod 41 to rise, and the pair of grippers 42, which are moving away from each other, open up and clamp against the inner wall of the annular part, holding the annular part. This invention utilizes the elastic force of the gripper spring 43 to open the pair of grippers 42 to hold the annular part, instead of using the V-shaped drive groove 411 to drive the wedge-shaped portions 421 to open the pair of grippers 42.

[0039] The gripper guide plate 33 has a gripper guide groove 331, and a pair of grippers 42 are engaged in the gripper guide groove. The end of the gripper away from the wedge-shaped part 421 is provided with a bent chuck 422. The gripper protrudes laterally from the gripper guide plate and can abut against the outer edge of the gripper guide plate to limit the range of the gripper 42 closing.

[0040] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
