Description

Technical Field

[0001] This invention relates to the field of electronic component manufacturing technology, and more specifically to a dual-station alternating hot-pressing and cooling integrated device. Background Technology

[0002] In the production of electronic components (such as chips, circuit board assemblies, and semiconductor packages), hot pressing and cooling are crucial processes to ensure structural stability and reliable performance. In traditional processes, hot pressing and cooling are typically performed separately on independent equipment or at separate workstations. After hot pressing at one workstation, the component must be manually or robotically transferred to a cooling station for further cooling. This step-by-step approach has several significant drawbacks: first, long process flow times negatively impact overall production efficiency; second, components are prone to positional shifts, collisions, or contamination during transfer, affecting finished product yield; and third, if hot-pressed components are not cooled promptly, residual stress or thermal deformation can occur, affecting product quality. Furthermore, many existing integrated equipment systems employ single-station cyclic operations, making simultaneous hot pressing and cooling impossible and resulting in low equipment utilization. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a rationally designed and easy-to-use dual-station alternating hot pressing and cooling integrated device. Through a drive mechanism, the device achieves alternating linkage between the two stations, enabling the hot pressing and cooling processes to be carried out simultaneously at different stations. This eliminates waiting time during process flow and significantly improves production efficiency. At the same time, the heat exchange mechanism assists in preheating at the hot pressing station and rapidly cools down at the cooling station, effectively improving the hot pressing effect and component shaping quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a mounting base and a hot press, wherein the hot press is suspended on one side above the mounting base, and the support plate of the hot press is fixed to the outer wall of one side of the mounting base; it further includes:

[0005] The first workstation platform abuts against the upper side of the mounting base. A second workstation platform is provided on one side of the first workstation platform, and the second workstation platform is movably configured to cooperate with the interior of the mounting base.

[0006] The drive mechanism is located in the mounting base and is connected to the first station platform and the second station platform.

[0007] The heat exchange mechanism consists of two parts, which are respectively fixed on the inner walls of both sides of the mounting base. The heat exchange mechanism is respectively configured to cooperate with and resist the No. 1 workstation platform and the No. 2 workstation platform.

[0008] Using the above technical solution, electronic components are placed on the first workstation platform. Then, the drive mechanism is activated, which moves the first workstation platform towards one side of the hot press. At the same time, the drive mechanism moves the second workstation platform away from the hot press. When they converge at the center of the mounting base, the second workstation platform moves downward into the mounting base. When the first workstation platform moves to the lower side of the hot press, the second workstation platform is located on the other side of the mounting base, allowing new electronic components to be placed. The hot press then performs a hot pressing operation on the electronic components on the first workstation platform. After the operation is completed, the drive mechanism is activated again, causing the first and second workstation platforms to exchange positions. At this time, the hot and cold exchange mechanism cools the hot-pressed electronic components. During the hot pressing process, the hot and cold exchange mechanism located on one side of the hot press can heat the electronic components to a certain extent.

[0009] As a further improvement of the present invention, the driving mechanism includes:

[0010] The fixed slide is movably mounted in the mounting base. The second workstation platform is connected to the fixed slide via a downward mechanism. The front and rear sides of the fixed slide are slidably mounted in the grooves on the front and rear inner walls of the mounting base.

[0011] Two sliding blocks are fixed symmetrically to the lower side wall of the No. 1 workstation platform. The sliding blocks are slidably disposed in the sliding grooves at the top of the front and rear side walls of the mounting base.

[0012] The conveying reciprocating lead screws consist of four screws, which are respectively threaded into the front and rear sides of two sliding blocks and a fixed slide. The conveying reciprocating lead screws are threaded into the side wall of the mounting base via bearings. The threads of the two corresponding upper and lower conveying reciprocating lead screws are arranged in opposite directions. The upper and lower symmetrical conveying reciprocating lead screws on the front side and the two symmetrical conveying reciprocating lead screws on the front and rear sides are connected by a synchronous pulley transmission assembly.

[0013] The drive motor is embedded and fixed in one side wall of the mounting base, and the output shaft of the drive motor is fixedly connected to one end of one of the conveying reciprocating lead screws.

[0014] With the above technical solution, the drive motor is started, which drives the connected reciprocating lead screw to rotate. The reciprocating lead screw, through a matching synchronous wheel transmission group, causes the other three reciprocating lead screws to rotate simultaneously. The upper reciprocating lead screw drives the No. 1 station platform to reciprocate through a sliding block, and the lower reciprocating lead screw drives the No. 2 station platform to reciprocate through a fixed slide. When the No. 2 station platform moves to the middle of the mounting base, it can be moved down through a lowering mechanism, so that the No. 1 station platform and the No. 2 station platform are misaligned, thus not affecting the movement of the two platforms.

[0015] As a further improvement of the present invention, the lowering mechanism includes:

[0016] The lifting plate consists of two plates, which are symmetrically fixed to the second workstation platform. The lifting plates are inserted through the two sides of the fixed slide table. The lifting plates are fitted and abut against the inner wall of the mounting base. Guide grooves are provided on both the front and rear inner walls of the mounting base, and the center of the guide grooves is inclined downward.

[0017] The guide rod consists of two rods, which are respectively fixed to the lower side of the side wall of the lifting plate away from the No. 2 workstation platform. A roller is fixed to the other end of the guide rod, and the guide rod and the roller are slidably arranged in the guide groove.

[0018] With the above technical solution, when the fixed slide table moves, the rollers and guide rods slide in the guide groove. When the guide rod moves to the lower side of the guide groove, the guide rod drives the lifting plate to move downward, which in turn drives the No. 2 station platform to move downward. When the No. 2 station platform moves to the lower side inside the mounting base and then follows the fixed slide table to the other side, it moves upward along the guide groove, so that the No. 2 station platform and the No. 1 station platform are on the same plane.

[0019] As a further improvement of the present invention, abutment wheels are fixed on the inner walls of both sides of the fixed slide, and the abutment wheels are slidably disposed in the grooves on the two inner walls of the lifting plate; this can increase the smoothness of the lifting plate when moving up and down.

[0020] As a further improvement of the present invention, the heat exchange mechanism includes:

[0021] The storage box is fixed on the inner wall of one side of the mounting base. Several heat exchange plates are equidistantly penetrating the top wall of the storage box. The upper side of the heat exchange plates is set to cooperate with and abut against the No. 1 station platform and the No. 2 station platform. Each heat exchange plate is provided with an arc-shaped through groove.

[0022] The diversion box is fixed to one side of the bottom wall inside the storage box. Several conveying pipes are inserted through and fixed on the top wall of the diversion box. The upper end of the conveying pipe is movably inserted into the vertical end of one side of the through groove through a sealing ring.

[0023] The support tubes are of several types and are inserted one-to-one into the cylindrical grooves in the center of the heat exchange plate. The lower end of the support tube passes through the lower side wall of the heat exchange plate and is fixed to the inner bottom wall of the storage box. A push spring is fixed inside the support tube, and the upper end of the push spring is fixed to the inner top wall of the heat exchange plate.

[0024] The pump is embedded and fixed in one side wall of the mounting base. The outlet of the pump is connected to the distribution box through a pipe, and the inlet pipe of the pump is located in the storage box.

[0025] A number of semiconductor cooling chips are equidistantly embedded and fixed on the bottom wall of the storage tank, and the semiconductor cooling chips are located on one side of the pipe at the inlet of the pump.

[0026] With the above technical solution, the heat exchange fluid is loaded into the storage tank. When the No. 1 or No. 2 station platform touches the upper side of the heat exchange plate, the pump is started. The pump draws the heat exchange fluid into the distribution box, and then through the conveying pipe to the through groove of the heat exchange plate. Under the push of the push spring, the heat exchange plate can maintain contact with the No. 1 or No. 2 station platform, which facilitates heat exchange. Then the heat exchange fluid is discharged from the other side of the through groove into the storage tank. The heat exchange fluid in the storage tank near the hot press is heated by the semiconductor cooling chip, while the heat exchange fluid in the storage tank on the other side is cooled by the semiconductor, which facilitates the circulation of the heat exchange fluid.

[0027] As a further improvement of the present invention, several connecting plates are equidistantly arranged on the upper side of the storage box, the connecting plates and the heat exchange plates are staggered, and the connecting plates are fixedly connected to the adjacent heat exchange plates.

[0028] Through the above technical solution, several connecting plates and heat exchange plates can be fixedly connected and spliced ​​into a whole, thereby increasing the heat exchange area.

[0029] As a further improvement of the present invention, a partition is fixed inside the side wall of the storage box away from the diversion box. The upper surface of the partition is set in the same plane as the outer top wall of the diversion box. Several liquid outlet pipes are fixed through the partition at equal intervals. The upper end of the liquid outlet pipe is movably inserted into the vertical end of the through groove on the other side. The lower side of the partition abuts against a filter box. The filter box is located below the liquid outlet pipe, and one side of the filter box is sealed through the side wall of the storage box.

[0030] With the above technical solution, the heat exchange liquid discharged through the through-channel is discharged into the filter box through the liquid outlet pipe. After a period of time, the filter box can be pulled out for cleaning to avoid blockage of the pump.

[0031] As a further improvement of the present invention, sealing rings are provided on the outer ring wall of the support pipe, the outer ring wall of the conveying pipe and the outer ring wall of the liquid outlet pipe, respectively. The sealing rings are respectively embedded and fixed on the inner ring wall of the through groove and the inner ring wall of the cylindrical groove.

[0032] Through the above technical solution, the sealing ring on the outer ring wall of the support pipe can seal the cylindrical groove, preventing the heat exchange fluid from affecting the push spring. The sealing ring on the outer ring wall of the conveying pipe can make the conveying pipe abut against the through groove, preventing the heat exchange fluid from leaking out through the gap between the conveying pipe and the inner ring wall of the through groove when conveying the heat exchange fluid, thus improving the efficiency of liquid conveying. The sealing ring on the outer ring wall of the outlet pipe can prevent the heat exchange fluid from being directly discharged into the storage tank.

[0033] As a further improvement of the present invention, a nozzle is suspended above one side of the mounting base. The nozzle is connected to external cooling gas. One end of the nozzle is fixed with a movable block by a support rod. The movable block is slidably disposed in a groove on one side wall of the mounting base. A drive reciprocating screw is threaded onto the movable block. The drive reciprocating screw is screwed into one side wall of the mounting base by a bearing. One end of the drive reciprocating screw is fixed with a drive motor. The drive motor is embedded and fixed in one side wall of the mounting base.

[0034] The above technical solution involves starting the drive motor, which in turn drives the reciprocating screw to rotate. The reciprocating screw then drives the moving block to move back and forth. The moving block, through a support rod, drives the nozzle to move back and forth. The nozzle draws in external cooling gas and sprays it onto the electronic components on the upper part of the first or second workstation platform, thereby achieving cooling from above.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] 1. The drive motor drives the No. 1 station platform and the No. 2 station platform to move synchronously in opposite directions through the conveying reciprocating screw. With the help of the lowering mechanism, the No. 2 station platform automatically sinks at the intersection, realizing the alternating entry and exit of the hot pressing station of the two stations, which significantly improves production efficiency.

[0037] 2. The No. 2 workstation platform is connected to the guide groove through the lifting plate. When it moves to the middle of the mounting base, the roller moves down along the guide groove, driving the platform to move down. After passing the intersection point, it automatically rises. The action is smooth and continuous, and the misalignment avoidance can be completed without additional power.

[0038] 3. The heat exchange liquid in the storage tank is diverted to the through groove of the heat exchange plate by the pump, and it is in close contact with the bottom surface of the platform for heat exchange. The side closer to the hot press is preheated by a semiconductor cooling chip, and the other side is cooled to achieve rapid cooling. The heat exchange plate is always in contact with the platform under the action of the push spring to ensure accurate and efficient temperature control.

[0039] 4. The nozzle moves back and forth under the drive of the reciprocating screw, uniformly spraying air to cool the electronic components from above, forming a three-dimensional cooling system through heat exchange with the bottom. The heat exchange fluid is returned and filtered by the filter box for reuse. It can be periodically extracted and cleaned to prevent blockage and ensure stable system operation.

The sealing rings 12 on the outer ring wall of the outlet pipe 10 can prevent the heat exchange fluid from being directly discharged into the storage tank 6-1.

[0073] Example 5:

[0074] See Figure 1-2 , Figure 8 As shown, based on Embodiment 1, a nozzle 13 is suspended above the right side of the mounting base 1. The nozzle 13 is connected to external cooling gas.

[0075] When using this invention, the electronic components are placed on the first workstation platform 3, and the drive motor 5-5 is started. The drive motor 5-5 drives the connected reciprocating lead screw 5-4 to rotate. The reciprocating lead screw 5-4, through a matching synchronous pulley transmission group, causes the other three reciprocating lead screws 5-4 to rotate simultaneously. The upper reciprocating lead screw 5-4 drives the first workstation platform 3 to reciprocate through the sliding block 5-3, and the lower reciprocating lead screw 5-4 drives the second workstation platform 4 to reciprocate through the fixed slide table 5-1. When the fixed slide table 5-1 moves, the roller 5-2-2 and the guide rod 5-2-3 slide in the guide groove 1-1. When the guide rod 5-2-3 moves to the lower side of the guide groove 1-1... When in position, guide rod 5-2-3 drives lifting plate 5-2-1 to move downward, thereby driving the second station platform 4 to move downward, so that the second station platform 4 moves to the lower side inside the mounting base 1 and then moves to the other side with fixed slide table 5-1, moving upward along guide groove 1-1, so that the second station platform 4 and the first station platform 3 are on the same plane. When the first station platform 3 moves to the lower side of hot press 2, the second station platform 4 is located on the other side of mounting base 1, so that new electronic components can be placed. At this time, the hot press 2 performs hot pressing operation on the electronic components on the first station platform 3. After the operation is completed, drive mechanism 5 is driven again, so that the first station platform 3 and the second station platform 4 are on the same plane. When the positions of the carrier platform 4 and 6 are changed, the heat exchange fluid is loaded into the storage tank 6-1. When the carrier platform 3 at station 1 or the carrier platform 4 at station 2 is in contact with the upper side of the heat exchange plate 6-2, the pumping pump 6-7 is started. The pumping pump 6-7 pumps the heat exchange fluid into the distribution box 6-3, and then through the conveying pipe 6-4 to the through groove 6-2-1 of the heat exchange plate 6-2. Under the push of the push spring 6-6, the heat exchange plate 6-2 can maintain contact with the carrier platform 3 at station 1 or the carrier platform 4 at station 2, thus facilitating heat exchange. Then, the heat exchange fluid is discharged from the other side of the through groove 6-2-1 into the storage tank 6-1. The heat exchange fluid entering the storage tank 6-1 near the hot press 2 is heated by the semiconductor cooling chip 6-8. The heat exchange liquid in the storage tank 6-1 on one side is cooled by a semiconductor, which facilitates the circulation of the heat exchange liquid. At the same time as cooling, the drive motor 16 is started. The drive motor 16 drives the drive reciprocating screw 15 to rotate. The drive reciprocating screw 15 drives the moving block 14 to move back and forth. The moving block 14 drives the nozzle 13 to move back and forth through the support rod. The nozzle 13 draws in the external cooling gas and sprays it onto the electronic components on the upper side of the first station platform 3 or the second station platform 4, so that the temperature can be cooled from above. The heat exchange liquid discharged through the through groove 6-2-1 is discharged into the filter box 11 through the liquid outlet pipe 10. After a period of time, the filter box 11 can be pulled out for cleaning to avoid the pump 6-7 from becoming blocked.

[0076] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0077] 1. The drive motor 5-5 is precisely linked with the conveyor reciprocating screw 5-4, so that the No. 1 station platform 3 and the No. 2 station platform 4 move synchronously in opposite directions and automatically misalign themselves, realizing the parallel and continuous operation of hot pressing and loading / unloading preparation, which greatly shortens the cycle time and significantly improves the overall production efficiency.

[0078] 2. The No. 2 station platform 4 moves precisely along the guide groove 1-1 via rollers 5-2-2, and automatically descends into the mounting base 1 at the intersection point, forming a three-dimensional misalignment with the No. 1 station platform 3, ensuring that the two platforms do not interfere with each other when exchanging positions. The entire movement process is smooth, stable and highly reliable.

[0079] 3. The heat exchange plate 6-2 is always in close contact with the platform under the action of the push spring 6-6. The pump 6-7 drives the heat exchange fluid to circulate in the closed loop. Combined with the precise temperature control of the semiconductor cooling chip 6-8, it provides efficient and uniform heating or cooling treatment for the hot-pressed electronic components.

[0080] 4. In addition to the heat exchange at the bottom, the reciprocating nozzle 13 continuously sprays cooling gas onto the electronic components from above, achieving uniform cooling in a three-dimensional manner, which significantly improves cooling efficiency and the stability of hot pressing quality.

[0081] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
