Description

Technical Field

[0001] This utility model relates to the field of hot pressing technology, and in particular to a hot pressing mechanism. Background Technology

[0002] The hot-pressing process of the OIS (Optical Image Stabilizer) base coil is the core step to ensure reliable bonding between the coil and the base and to achieve electromagnetic drive performance.

[0003] As the electronics manufacturing industry continues to develop towards higher precision, higher efficiency, and automation, the hot-press bonding process for electronic components has become a crucial step. In electronic devices, the base coil, as a core component, directly affects the electrical performance and lifespan of the product through its reliable bonding to the base fixture. Traditional hot-pressing equipment suffers from the following technical drawbacks: low unloading efficiency, requiring manual assistance for unloading after hot pressing, resulting in low efficiency and potential product damage; and the ability to process only a single workpiece in a single hot-press cycle, failing to meet the demands of mass production.

[0004] Therefore, this application proposes a hot pressing mechanism. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a hot pressing mechanism.

[0006] An embodiment of this utility model provides a hot pressing mechanism, comprising:

[0007] Chassis;

[0008] A hot pressing assembly includes multiple guide columns installed inside a chassis. A movable plate capable of moving up and down is connected to each guide column. A stripping plate is connected to the lower end of the movable plate. Multiple cylinders are provided at the upper end of the stripping plate. A hot pressing head is fixed to the output end of each cylinder. A support platform is installed inside the chassis. A base fixture is fixed on the support platform. A placement slot is provided at the upper end of the base fixture to match the position and number of the hot pressing heads. A base coil is placed in the placement slot.

[0009] Furthermore, a support plate is fixed to the upper end of each of the guide columns, and an electric push rod is mounted on the support plate. The output end of the electric push rod is fixedly connected to the upper end of the movable plate.

[0010] Furthermore, two connecting frames are fixed to the lower end of the movable plate, and the connecting frames are fixedly connected to the upper end of the stripping plate.

[0011] Furthermore, a guide plate is installed on the connecting frame, and the hot press head passes through the guide plate and slides against it.

[0012] Furthermore, when the stripper plate abuts against the base fixture, the stripper plate is opposite to the upper end of the base coil.

[0013] Furthermore, a sliding guide sleeve is fitted onto the guide post, and the movable plate is fixedly connected to the guide sleeve.

[0014] Furthermore, a temperature control structure is installed on the support plate, and the temperature control structure is connected to the hot press head.

[0015] Furthermore, a mounting plate is installed on the connecting frame, and the cylinder is mounted on the mounting plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the hot press head rises, the stripping plate and the base fixture work together to clamp the base coil, preventing the product from moving up with the hot press head, thus achieving non-destructive stripping and reducing manual intervention. The base fixture is equipped with multiple placement slots, which can simultaneously hot press multiple base coils, improving equipment utilization and making it suitable for mass production scenarios.

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown, this utility model embodiment proposes a hot pressing mechanism, including:

[0025] Chassis 1;

[0026] Hot pressing assembly; the hot pressing assembly includes multiple guide columns 2 installed inside the housing 1, with movable plates 7 that can move up and down connected to the guide columns 2, and support plates 5 fixed to the upper ends of the multiple guide columns 2, with electric push rods 3 installed on the support plates 5, and the output end of the electric push rods 3 fixedly connected to the upper end of the movable plates 7; wherein, guide sleeves 6 are slidably fitted on the guide columns 2, and the movable plates 7 are fixedly connected to the guide sleeves 6.

[0027] The lower end of the movable plate 7 is connected to the stripping plate 11. Two connecting frames 10 are fixed to the lower end of the movable plate 7. The connecting frames 10 are fixedly connected to the upper end of the stripping plate 11. Multiple cylinders 12 are provided at the upper end of the stripping plate 11. An mounting plate 16 is installed on the connecting frame 10. The cylinders 12 are installed on the mounting plate 16. A hot press head 13 is fixed to the output end of the cylinder 12. A guide plate 14 is installed on the connecting frame 10. The hot press head 13 passes through the guide plate 14 and slides against it to ensure stable movement of the hot press head 13.

[0028] When the stripper plate 11 abuts against the base fixture 9, the upper end of the stripper plate 11 is opposite to the base coil 15, ensuring that the hot press head 13 is directly opposite the base coil 15. It should be noted that the hot press head 13 does not completely cover the base coil 15. Its corner part is blocked by the stripper plate 11. That is, when the hot press head 13 moves upward, the stripper plate 11, together with the base fixture 9, will limit the base coil 15 so that it will not move upward with the hot press head 13, thus achieving stripping.

[0029] A temperature control structure 4 is installed on the support plate 5. The temperature control structure 4 is connected to the hot press head 13 and monitors and controls the temperature of the hot press head 13 in real time to ensure that the hot press adhesive cures at the optimal temperature. The temperature control structure 4 adopts a PID control algorithm and supports temperature setting, display and alarm functions. A K-type thermocouple is installed inside the hot press head 13 to realize real-time temperature feedback and adjustment.

[0030] A support platform 8 is installed inside the chassis 1. A base fixture 9 is fixed on the support platform 8. The upper end of the base fixture 9 is provided with a placement slot 17 that matches the position and quantity of the hot press head 13. A base coil 15 is placed in the placement slot 17.

[0031] Place the base coil 15 to be hot-pressed into the placement slot 17 of the base fixture 9, ensuring that the position of the base coil 15 is directly opposite the hot-pressing head 13.

[0032] The output end of the electric push rod 3 pushes the moving plate 7 downward. The moving plate 7 descends smoothly along the guide column 2 through the guide sleeve 6, driving the stripping plate 11, the connecting frame 10 and the cylinder 12 to move down synchronously.

[0033] The cooperation between the guide post 2 and the guide sleeve 6 ensures that the moving plate 7 moves vertically, avoiding deviation or shaking.

[0034] When the stripper plate 11 descends to contact the upper surface of the base fixture 9, the stripper plate 11 is opposite to the upper end of the base coil 15, forming a preliminary positioning. At this time, the hot press head 13 is located directly above the base coil 15 and maintains a certain gap with the base coil 15 (determined by the stroke of the cylinder 12).

[0035] The output end of cylinder 12 extends out, pushing the hot press head 13 to move downward along the guide plate 14. The guide plate 14 ensures that the hot press head 13 moves vertically and avoids deflection.

[0036] The hot pressing head 13 is pressed down to contact the base coil 15 and kept at a constant temperature (e.g., 160℃~180℃) under the control of the temperature control structure 4 to hot press the base coil 15. Since there are multiple placement slots 17, multiple base coils 15 can be hot pressed at the same time, and the base coil 15 is hot pressed at a preset pressure (e.g., 0.6MPa).

[0037] After the hot press head 13 contacts the base coil 15, the hot press adhesive cures at high temperature, achieving a reliable bond between the base coil 15 and the base fixture 9. The hot pressing time is controlled by preset parameters (e.g., 40s to 50s) to ensure that the hot press adhesive is fully cured.

[0038] After the hot pressing time is over, the output end of cylinder 12 retracts, driving the hot pressing head 13 to reset upward along the guide plate 14 and disengage from the base coil 15.

[0039] The output end of the electric push rod 3 retracts, pulling the moving plate 7 upward along the guide column 2, which in turn drives the stripping plate 11, the connecting frame 10 and the cylinder 12 to move upward synchronously and detach from the base fixture 9.

[0040] The operator takes out the hot-pressed base coil 15 from the placement slot 17 of the base fixture 9 and checks the hot-pressing quality (such as bonding strength, appearance defects, etc.).

[0041] Repeat the above steps to place the new base coil 15 into the placement slot 17 and begin the next round of hot pressing.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
