Description

Technical Field

[0001] This invention relates to the field of device assembly equipment technology, and in particular to a device assembly pressure holding device, and an assembly mechanism designed based on the assembly pressure holding device. Background Technology

[0002] During the assembly of various equipment, some components require pressure holding to ensure reliability due to process requirements such as adhesive curing, structural sealing, or interface bonding. Products requiring pressure holding during assembly fall into three categories: 1. Components requiring adhesive curing, including potting compounds, thermally conductive interface materials, and structural adhesive bonding components; 2. Precision mechanically mating components, including connector terminals, waterproof seals, and crimp terminals; 3. Multilayer composite encapsulated components, including sensor packages, multilayer capacitors / inductors, and flexible circuit bonding.

[0003] When assembling speakers, glue is required, so pressure needs to be maintained for 10-20 minutes after assembly. Maintaining pressure (applying continuous and stable pressure to ensure a tight fit between components) is crucial for ensuring sound quality and stability, especially in scenarios involving sealing, vibration damping, and structural robustness. For example, in structures with sealed and fixed enclosures, the speaker unit must be evenly pressurized at the junction with the enclosure to prevent sound leakage or resonance noise.

[0004] Taking the assembly of a speaker into AR glasses as an example, during the speaker assembly process, after the speaker is assembled into the inner cavity of the temple, a certain pressure needs to be applied to the speaker to ensure the airtightness between the speaker and the temple. The time between assembling the speaker and applying the pressure is a crucial factor in ensuring the airtightness between the speaker and the temple. The shorter the time interval, the better the airtightness of the product. Therefore, shortening the time between assembly and pressure holding is an important prerequisite for ensuring the airtightness of the product. Summary of the Invention

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0036] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a device assembly pressure holding device includes a pressure cap mechanism for pressing the device into a target product and holding the pressure. The pressure cap mechanism is connected to a pressure-in driving device. In the pressure holding state, the pressure cap mechanism is fastened to a tooling 1 that fixes the target product. A fastening control device is installed between the pressure-in driving device and the pressure cap mechanism.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, the capping mechanism includes a capping body 21. The capping body 21 has symmetrically mounted grippers on both sides that are engaged with the tooling 1. The engagement control device is connected to the capping body 21 and drives the grippers to open to both sides. The capping body 21 is equipped with an air suction assembly connected to the vacuum circuit for picking up the device. The capping body 21 is also equipped with a pressure head assembly for applying pressure to the device.

[0038] When the capping mechanism presses the device into the target product, the pressure head assembly applies a certain pressure to the device; the fastening control device disengages from the capping body 21, the open grippers reset and fasten with the tooling 1, and the capping mechanism continuously applies pressure to the device to maintain pressure. The device is pressure maintained while being assembled, and the assembly and pressure maintenance are seamlessly connected, which not only improves work efficiency, but also greatly improves the airtightness and fit of the product.

[0039] According to some embodiments of the present invention, such as Figure 1 As shown, the pressing drive device includes a first single-axis robot 32, whose slider is connected to the fastening control device. The first single-axis robot 32 can drive the fastening control device to move, thereby driving the capping mechanism to move, thus pressing the device into the target product through the capping mechanism. The single-axis robot includes a servo motor, a linear track, and a slider. The servo motor drives the slider to move along the linear track. Single-axis robots are mature existing technology, and their structure and working principle will not be described in detail here.

[0040] According to some embodiments of the present invention, such as Figure 2 As shown, the fastening control device includes two parallel clamping plates 41. A drive cylinder is installed between the two clamping plates 41 to control their approach and distance. Each clamping plate 41 includes a clamping part 42 connected to the capping body 21 and an opening drive part 43 that cooperates with the grippers. Further, each clamping plate 41 has two clamping parts 42, located on both sides of the opening drive part 43. The end of each clamping part 42 has a folded edge 44 extending towards the capping body 21, and the capping body 21 has a groove 22 that cooperates with the folded edge 44. The opening drive part 43 includes a clearance area on the clamping plate 41. The structure of the clearance area matches the grippers, so that when the fastening control device is connected to the capping mechanism, the clearance area can precisely drive the grippers to open. The structural design of the clamping plate 41 and the drive cylinder can be referenced from pneumatic fingers.

[0041] According to some embodiments of the present invention, such as Figure 3 and Figure 5As shown, the gripper includes a gripper shaft 23 hinged to the cap body 21. One end of the gripper shaft 23 extends towards the side of the fastening control device and is equipped with a rotating wheel 24. The other end of the gripper shaft 23 extends away from the fastening control device and is provided with a pressure-holding locking block 25. A torsion spring (not shown in the figure) is installed between the gripper shaft 23 and the cap body 21. Specifically, the middle part of the gripper shaft 23 is hinged to the cap body 21, and the torsion spring is installed between the gripper shaft 23 and the cap body 21 near the hinge point. When the fastening control device releases the gripper, the torsion spring provides a resetting torque for the gripper. The pressure-holding locking block 25 is at a certain angle to the gripper shaft 23, and the pressure-holding locking blocks 25 of the two grippers extend towards each other.

[0042] When the fastening control device is working, the drive cylinder drives the two clamping plates 41 to open. The two clamping plates 41 move to both sides of the capping mechanism, and the clamping plates 41 close. The folded edge 44 of the clamping part 42 of the clamping plate 41 fastens into the groove 22 of the capping body 21. During this process, the opening drive part 43 of the clamping plate 41 contacts the rotating wheel 24 of the gripper and pushes the end of the rotating wheel 24 and the gripper shaft 23 to swing inward, and the other end of the gripper opens. The design of the rotating wheel 24 can reduce the frictional resistance during the pushing process and reduce the wear of the components.

[0043] According to some embodiments of the present invention, such as Figure 4 As shown, the pressure head assembly includes a central pressure head 51 floatingly mounted on the pressure cap body 21 and side pressure heads 52 distributed around the central pressure head 51. A first pressure-holding spring 53 is installed between the central pressure head 51 and the pressure cap body 21, and a second pressure-holding spring 54 is installed between the side pressure heads 52 and the pressure cap body 21. During device installation, the central pressure head 51 and the side pressure heads 52 pre-compress the first pressure-holding spring 53 and the second pressure-holding spring 54. After installation, under the action of the first pressure-holding spring 53 and the second pressure-holding spring 54, the central pressure head 51 and the side pressure heads 52 apply a certain pressure-holding pressure to the device. The clamping plate 41 of the fastening control device releases the pressure cap mechanism, and the clamp returns to its original position under the action of the torsion spring. The clamp engages with the tooling 1 of the target product with the cooperation of the pressure-holding locking block 25. After assembly, the pressure-holding pressure continues to be provided to the device. During the switching between assembly and pressure holding, the pressure cap mechanism never releases the pressure on the device, greatly improving the airtightness of the product. Since the pressure holding of the device requires a large pressure holding force, taking the assembly of a loudspeaker as an example, let's introduce a technical parameter setting for the pressure holding spring. Under the premise of limited space, the pressure holding spring is pre-compressed. The elastic coefficient of the second pressure holding spring 54 is 2N / mm, the initial pre-compression is 2.2mm and the spring force is 4.4N. The elastic coefficient of the first pressure holding spring 53 is 2.9N / mm, the initial pre-compression is 2.1mm and the spring force is 6.1N. The compression during pressure holding is preferably 1mm.

[0044] According to some embodiments of the present invention, the air suction assembly includes a venting rod 61 slidably mounted within the pressure cap body 21. One end of the venting rod 61 is connected to the vacuum passage, and the other end is connected to the central pressure head 51. The central pressure head 51 is provided with a plurality of vent holes 62 communicating with the inner cavity of the venting rod 61. A first pressure-holding spring 53 is ringed around the venting rod 61, that is, the first pressure-holding spring 53 is fitted onto the venting rod 61, and the venting rod 61 is connected to the pressure cap body 21 through the first pressure-holding spring 53 ring. During operation, the vacuum passage forms a negative pressure zone in the central pressure head 51 through the venting rod 61 and the vent holes 62, relying on the negative pressure to adsorb the device, thereby completing the device pick-up.

[0045] According to some embodiments of the present invention, a vent pipe 63 communicating with a vacuum circuit is installed on the pressing drive device. One end of the vent pipe 63 is connected to the vacuum circuit, and the other end of the vent pipe 63 extends toward the capping mechanism. When the fastening control device is connected to the capping mechanism, the vent pipe 63 mates with the vent rod 61, at which time the vent rod 61 communicates with the vacuum circuit through the vent pipe 63. Of course, the vent pipe 63 can also be set on the fastening control device, and the specific installation position can be determined according to needs.

[0046] like Figure 8 , Figure 9 and Figure 10 As shown, a device assembly mechanism includes a device loading device, a precision positioning device 7, and an assembly pressure holding device as described above. The precision positioning device 7 includes a loading station and a unloading station that cooperate with the device loading device and the assembly pressure holding device. The precision positioning device 7 includes a precision positioning table 71 that slides between the loading station and the unloading station. A precision positioning component is provided on the precision positioning table 71.

[0047] The various devices described above work together to complete the assembly of the components. Upon completion of assembly, the device switches to a pressure-holding state, ensuring a seamless transition between assembly and pressure holding. This not only improves work efficiency but also significantly enhances the airtightness of the product and improves product quality.

[0048] According to some embodiments of the present invention, such as Figure 11 and Figure 12 As shown, the precision positioning component includes a positioning chamber 72 disposed on the precision positioning stage 71 and matched with the device. A push block 73 is provided on one side of the positioning chamber 72 to push the device into position. The push block 73 is connected to a push cylinder 74. After the device is placed into the positioning chamber 72, the push cylinder 74 actuates, using the push block 73 to push the device into position, achieving precise positioning of the device and providing a basic guarantee for subsequent device unloading processes.

[0049] According to some embodiments of the present invention, such as Figure 8 , Figure 9 and Figure 10 As shown, the device loading device includes a second transfer mechanism and a second picking mechanism. The second transfer mechanism includes a second linear motor 81 and a second single-axis robot 82. The second picking mechanism includes a ventilation shaft (not shown) connected to the second single-axis robot 82, and the ventilation shaft is connected to the vacuum circuit. The second picking mechanism transfers the device to the precision positioning device 7. Under the control of the vision guidance system, the device loading device is used to transport the device in the tray to the precision positioning device 7. During operation, the second single-axis robot 82 moves along the second linear motor 81 to above the tray. The second single-axis robot 82 works, driving the second picking mechanism to move downward. The negative pressure area at the end of the ventilation shaft aligns with the device and picks the device from the tray. The second picking mechanism moves upward under the control of the second single-axis robot 82. The second single-axis robot 82 moves along the second linear motor 81 to above the precision positioning device 7. When the device is aligned with the positioning chamber 72, the second single-axis robot 82 controls the second picking mechanism to move downward and place the device into the positioning chamber 72. Then the push cylinder 74 is activated, and the push block 73 pushes the device into place.

[0050] According to some embodiments of the present invention, a first transfer mechanism is also included, on which the assembly pressure holding device is mounted. The first transfer mechanism includes a first linear motor 31. The assembly pressure holding device moves along the first linear motor 31 to above the precision positioning device 7. When the air suction component of the capping mechanism corresponds to the device position, the first single-axis robot 32 of the assembly pressure holding device moves, driving the capping mechanism to move downward. The air suction component is adsorbed and connected to the device. The push cylinder 74 of the precision positioning device 7 moves, the push block 73 retracts, releasing the push force on the device. The first single-axis robot 32 moves, driving the capping mechanism and the device to move upward. Then, the first single-axis robot 32 transports the device to the assembly station along the first linear motor 31.

[0051] Let's take the assembly of a loudspeaker as an example to illustrate the workflow of the above-mentioned component assembly mechanism:

[0052] 1. The second transplanting mechanism drives the second material picking mechanism to pick up the speaker from the material tray through air suction and place it into the precision positioning device 7 at the loading station, guided by vision.

[0053] 2. In the precision positioning device 7, the side-push cylinder pushes the speaker and positions it, and then the precision positioning device 7 moves to the unloading station;

[0054] 3. The first transfer mechanism drives the assembly and pressure holding device to pick up the capping mechanism from the return conveyor belt using the fastening control device, and then moves it to the unloading station of the precision positioning device 7. The air suction component on the capping mechanism picks up the speaker and then transports the picked-up speaker to the fixture 1 where the target product is fixed. The capping mechanism moves down and presses the speaker into the target product. After assembly, it is pressed down by 0.8 to 1.2 mm (preferably 1 mm). The jaws of the capping mechanism are fastened together with the fixture 1 that fixes the target product. The pressure head component of the capping mechanism provides continuous pressure for the speaker. Then the fastening control device disengages from the capping mechanism. The capping mechanism is fastened to the fixture 1 and moves to the subsequent station. When the pressure holding time ends, the capping mechanism is removed from the fixture 1 and recycled.

[0055] The target product for speaker assembly can be the temple of AR glasses or other electronic devices that require speaker mounting. Different fixtures are designed according to the different structures of the target products.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
