Description

Technical Field

[0001] This utility model relates to the field of smart watch assembly technology, and in particular to a watch assembly fixture. Background Technology

[0002] One of the assembly steps for a smartwatch is installing the circuit board into the watch frame. The watch frame contains several FPC ribbon cables. To prevent the FPC ribbon cables from being pressed down by the circuit board, the FPC ribbon cables are usually pushed to the inner wall of the watch frame before the circuit board is installed.

[0003] Currently, circuit boards are mainly installed into the watch frame manually. Workers first manually guide the FPC cables to the inner wall of the watch frame, and then manually install the circuit boards. This manual installation method is inefficient. While existing robotic arms can install the circuit boards, they cannot guide the FPC cables to the inner wall of the watch frame.

[0004] Therefore, this utility model is dedicated to developing a watch assembly fixture, which provides downstream robotic arms with circuit boards and watch frames with pre-organized FPC cables, so that the downstream robotic arms can place the circuit boards into the watch frames, thereby enabling mechanized smart watch assembly operations, thereby reducing labor costs and improving production efficiency.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To achieve the above objectives, this utility model provides a watch assembly fixture, comprising:

[0008] Jig base plate;

[0009] The watch frame fixture is located at one end of the fixture base plate and has a watch frame placement groove at the top for the watch frame to enter from top to bottom.

[0010] A plurality of folded cable assemblies are arranged along the edge of the watch frame component placement slot and rotatably connected to the watch frame fixture; wherein, the folded cable assembly has an inward turning state in which it rotates inward to press the FPC cable in the watch frame against the inner frame wall of the watch frame, and an outward turning state in which it rotates outward to disengage from the watch frame component placement slot.

[0011] A PCB fixture, located at the other end of the fixture base plate, is used to clamp and fix the circuit board to be installed into the frame.

[0012] Optionally, the folding wire assembly includes a rotating block rotatably connected to the watch frame fixture, and a wire pressing plate with one end connected to the rotating block.

[0017] Optionally, the resilient link clamping assembly includes:

[0018] The first clamping block is located on one side of the PCB placement slot, and the upper part of the first clamping block is rotatably connected to the PCB positioning plate through a horizontal rotating shaft.

[0020] A movable clamping plate, one end of which is hinged to the other end of the rotating connecting rod, and the other end of the movable clamping plate is provided with a second clamping block that protrudes upward to the other side of the PCB placement slot.

[0021] Optionally, the elastic link clamping assembly further includes:

[0022] A clamping spring is located on the side of the second clamping block away from the PCB placement slot, and is used to drive the second clamping block to move toward the first clamping block so as to cooperate with the first clamping block to laterally clamp the circuit board.

[0023] Optionally, the top of the second clamping block is provided with an arc-shaped guide surface for the circuit board to enter the PCB placement slot from top to bottom.

[0024] Optionally, the upper part of the first clamping block is provided with a limiting part that protrudes toward the PCB placement slot to restrict the circuit board from moving upward away from the PCB placement slot.

[0025] Optionally, a pressure plate assembly for pressing the circuit board downwards within the frame is also included.

[0026] Optionally, the pressure plate assembly includes a pressure plate base fixed to the bottom of the fixture, an extension pressure plate with one end hinged to the top of the pressure plate base, and a spring pressure head mounted on the other end of the extension pressure plate for pressing the circuit board downward.

[0027] Optionally, the pressure plate assembly further includes a limiting baffle that is slidably connected to the pressure plate base, and a baffle spring that drives the limiting baffle to slide above the extended pressure plate so that the spring pressure head continuously presses the circuit board inside the frame.

[0048] See Figures 1-3 This utility model provides a watch assembly fixture, including a fixture base plate 1, a watch frame fixture 2, several folded wire assemblies 3, and a PCB fixture 4.

[0049] The watch frame fixture 2 is located at one end of the fixture base plate 1, and has a watch frame placement slot 201 at its top for the watch frame to enter from top to bottom. Each of the folding cable assemblies 3 is arranged along the edge of the watch frame placement slot 201 and is rotatably connected to the watch frame fixture 2; wherein, the folding cable assembly 3 has an inward-turning state where it rotates inward to press the FPC cable inside the watch frame against the inner frame wall of the watch frame, and an outward-turning state where it rotates outward to disengage from the watch frame placement slot 201. The PCB fixture 4 is located at the other end of the fixture base plate 1 and is used to clamp and fix the circuit board to be installed into the watch frame.

[0050] The watch assembly fixture provided in this embodiment first rotates each folded cable assembly 3 outward to an outward-facing state, then places the watch frame into the watch frame placement slot 201. Subsequently, each folded cable assembly 3 rotates inward to an inward-facing state, so that each folded cable assembly 3 presses the FPC cable inside the watch frame tightly against the inner frame wall of the watch frame, thereby obtaining a watch frame with the FPC cable neatly arranged. Next, the circuit board is inserted into the PCB fixture 4, and the watch assembly fixture can be sent to the downstream robot arm. Finally, the downstream robot arm removes the circuit board from the PCB fixture 4 and inserts it into the watch frame with the FPC cable neatly arranged, completing the mechanized assembly of the smartwatch.

[0051] Therefore, the watch assembly fixture provided by this utility model can provide the downstream robot with circuit boards and watch frames with pre-organized FPC cables, so that the downstream robot can put the circuit boards into the watch frames, thereby realizing mechanized smart watch assembly operations, thereby reducing labor costs and improving production efficiency.

[0052] Optionally, the folding wire assembly 3 includes a rotating block 301 rotatably connected to the watch frame fixture 2, and a wire pressing plate 302 with one end connected to the rotating block 301.

[0053] The other end of the pressure plate 302 is used to rotate into the frame to press the corresponding FPC cable.

[0054] The PCB fixture 4 includes a PCB positioning plate 401 and an elastic linkage clamping assembly 402. The PCB positioning plate 401 is provided with a PCB placement slot 4011 for placing the circuit board. The elastic linkage clamping assembly 402 is located on both sides of the PCB placement slot 4011 and is used to clamp the circuit board.

[0055] The elastic link clamping assembly 402 includes a first clamping block 4021, a rotating link 4022, a movable clamping plate 4023, and a clamping spring 4024.

[0056] The first clamping block 4021 is located on one side of the PCB placement slot 4011, and the upper part of the first clamping block 4021 is rotatably connected to the PCB positioning plate 401 via a horizontal pivot. One end of the rotating connecting rod 4022 is hinged to the lower end of the first clamping block 4021. One end of the movable clamping plate 4023 is hinged to the other end of the rotating connecting rod 4022, and the other end of the movable clamping plate 4023 is provided with a second clamping block 4023a that protrudes upward to the other side of the PCB placement slot 4011. The clamping spring 4024 is located on the side of the second clamping block 4023a away from the PCB placement slot 4011, and is used to drive the second clamping block 4023a to move toward the first clamping block 4021, so as to cooperate with the first clamping block 4021 to laterally clamp the circuit board.

[0057] The second clamping block 4023a has an arc-shaped guide surface 4023b on its top for the circuit board to enter the PCB placement slot 4011 from top to bottom.

[0058] Furthermore, the upper part of the first clamping block 4021 is provided with a limiting part 4021a that protrudes toward the PCB placement slot 4011 to restrict the circuit board from moving upward away from the PCB placement slot 4011.

[0059] In this embodiment, the working process of PCB fixture 4 is as follows:

[0060] (1) Insert one end of the circuit board into the lower part of the limiting part 4021a at an angle downwards;

[0061] (2) Place one end of the circuit board on the arc-shaped guide surface 4023b;

[0062] (3) Press the circuit board down, and push the first clamping block 4021 and the second clamping block 4023a outward respectively at both ends of the circuit board. Finally, under the action of the clamping spring 4024, the first clamping block 4021 and the second clamping block 4023a clamp the circuit board laterally.

[0063] When the circuit board needs to be removed later, simply lift the end of the circuit board closest to the second clamp 4023a upwards.

[0064] Optionally, the watch assembly fixture also includes a pressure plate assembly 5 for pressing the circuit board downwards within the watch frame.

[0065] Furthermore, the pressure plate assembly 5 includes a pressure plate base 501 fixed on the bottom of the fixture, an extension pressure plate 502 with one end hinged to the top of the pressure plate base 501, a spring pressure head 503 installed on the other end of the extension pressure plate 502 and used to press the circuit board downward, a limiting baffle 504 slidably connected to the pressure plate base 501, and a baffle spring 505 that drives the limiting baffle 504 to slide above the extension pressure plate 502 so that the spring pressure head 503 continuously presses the circuit board in the frame.

[0066] After the downstream robotic arm loads the circuit board into the watch frame, it rotates the extension pressure plate 502 inward, causing the spring pressure head 503 to press down on the circuit board inside the watch frame. At this time, under the driving action of the baffle spring 505, the limit baffle 504 automatically slides outward above the extension pressure plate 502, restricting the extension pressure plate 502 from rotating outward, thereby maintaining the pressure on the circuit board so that the watch assembly fixture can be transported to the next station, preventing the circuit board from detaching from the watch frame during the transportation process.

[0067] In summary, the watch assembly fixture provided in this embodiment has the following advantages:

[0068] ① Reduce labor costs: By using the folding cable assembly 3 and PCB fixture 4, the watch assembly fixture can automatically organize the FPC cables and fix the circuit boards, reducing manual intervention and improving the automation level of the production line.

[0069] ② Improve production efficiency: Traditional manual assembly process is time-consuming, while this fixture can quickly organize FPC cables and fix circuit boards, making the assembly process faster and thus improving production efficiency.

[0070] ③ Easy to operate: The fixture is designed with ease of operation in mind. The circuit board can be fixed and the FPC cable can be arranged by simple actions such as rotation and clamping.

[0071] ④ Reduce assembly errors: The limiting part 4021a and the arc-shaped guide surface 4023b in the fixture can ensure that the circuit board is correctly placed and fixed.

[0072] ⑤ Maintaining a compressed state: The design of the pressure plate assembly 5 ensures that the circuit board remains compressed within the frame and will not come off even during transportation, thus guaranteeing the stability of the assembly.

[0073] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
