Description

Technical Field

[0001] This invention relates to the field of automatic opening structure technology, and more specifically to an automatic opening structure for a chip packaging oven. Background Technology

[0002] Chip packaging is a crucial step in semiconductor manufacturing. It involves placing chips into specific package structures to protect them and enable them to connect with other electronic components. Drying is a common process step in packaging, aimed at removing moisture from the chip or package structure to improve product reliability and stability. Drying is typically carried out in an oven equipped with a heater. The heat generated by the heater evaporates the moisture, thus drying the chip. During the drying process, it is essential to ensure precise control of parameters such as temperature, humidity, and time within the oven to guarantee consistent and reliable drying results.

[0003] The existing automatic opening structure of chip packaging ovens usually requires workers to manually open the oven to remove the packaged chips. However, when workers perform this operation, hot air from inside the oven rushes out rapidly. Because the temperature of this hot air is extremely high, it can easily cause severe burns to the workers' skin, which not only threatens the safety and health of the workers, but may also affect production efficiency and product quality. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic opening structure for a chip packaging oven to solve the problems existing in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic opening structure for a chip packaging oven, comprising an oven body, a dual-axis motor located at the center of the top of the oven body, a piston tube located on one side of the top of the oven body, a feeding plate located inside the oven body, a first bevel gear fixedly connected to one side of the dual-axis motor, a second bevel gear fixedly connected to the other side of the dual-axis motor, a first planar gear located on one side of the second bevel gear, a threaded rod fixedly connected to one side of the first planar gear, a fixed frame located outside the threaded rod, and a movable block located inside the fixed frame. A connecting seat is fixedly connected to one side, and a movable rod is fixedly connected to the bottom of the connecting seat. A guide plate is provided on the outside of the movable rod, and a door connecting plate is provided on one side of the guide plate. A locking block is fixedly connected to one side of the movable rod, and a movable locking groove is opened inside the door connecting plate. A connecting pipe is provided on one side of the piston tube, and an air outlet is fixedly connected to the top of the piston tube. A piston plate is provided inside the piston tube, and a telescopic rod is fixedly connected to one side of the piston plate. A connecting block is fixedly connected to one side of the telescopic rod, and a connecting rod is fixedly connected to one side of the connecting block. A second planar gear is fixedly connected to one side of the connecting rod.

[0006] Furthermore, an oven door is provided on one side of the oven body, and a transparent observation window is fixedly connected inside the oven door. A support base plate is fixedly connected to the bottom of the oven body, and support feet are fixedly connected around the bottom of the support base plate. A control panel is fixedly connected to the top of one side of the oven body, and a pressure relief device is fixedly connected to the other side of the oven body. A temperature detection device is fixedly connected to the top inside the oven body, and a support plate is provided at the bottom of the feeding plate.

[0007] Furthermore, a retaining ring is fixedly connected to one side of the feeding plate, a pull ring is provided on one side of the retaining ring, a connecting rope is fixedly connected to one side of the pull ring, a locking hook is fixedly connected to one side of the connecting rope, a fixed base is fixedly connected to one side of the locking hook, and a locking rod is provided at the bottom of the fixed base.

[0008] Furthermore, the second bevel gear meshes with the first planar gear, the fixed frame has a movable groove inside, the movable block moves in the movable groove inside the fixed frame through the threaded rod, the fixed frame has movable grooves on both sides of the bottom, the connecting seat moves in the movable grooves on both sides of the bottom of the fixed frame, and the connecting seat is fixedly connected to the movable rod through a fixed pin.

[0009] Furthermore, the second planar gear meshes with the first bevel gear, and the connecting pipe is fixedly connected to the pressure relief device.

[0010] Furthermore, the control panel electrically controls a dual-axis motor, the oven door connecting plate is fixedly connected to the top of the oven door with bolts, the guide plate is fixedly connected to the top of the oven body, and the top of the oven body is provided with a placement groove.

[0011] Furthermore, the locking rod is fixedly connected to the inner wall of the oven body, a bearing is provided at the connection between the fixed base and the locking hook, and the diameter of the pull ring is larger than the inner diameter of the retaining ring.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. This invention features an opening device. The control panel controls the rotation of the second bevel gear on the other side of the dual-axis motor. The output shaft of the bevel gear drives the threaded rod to rotate, which in turn causes the movable block to slide back and forth horizontally inside the fixed frame. The movable block is fixedly connected to the connecting seat, allowing the movable rod to slide back and forth horizontally with the movable block, thereby opening the door connecting plate outward. This effectively solves the technical problems of inconvenience and low level of intelligence caused by the need to manually pull a handle to open and close the door in the prior art, thus realizing an automatic opening and closing function.

[0014] 2. This invention, through the inclusion of a movable rod and other devices, allows the pressure relief device to be opened after the materials inside the oven body have been processed. Simultaneously, the dual-axis motor is activated via the control panel, causing the first bevel gear on one side of the motor to rotate. This, in turn, drives the second planar gear to rotate via its output shaft during startup, causing the connecting block to move along the axis of the connecting rod. This results in the telescopic rod repeatedly extending and retracting, causing the piston plate to move linearly inside the piston tube. Consequently, the hot airflow inside the pressure relief device is drawn into the piston tube and discharged from the outlet. This effectively solves the problem of the high-temperature hot airflow inside the oven rushing out rapidly when the oven door is opened, which could burn workers.

[0015] 3. The present invention has a self-locking device. When the feeding plate needs to be pulled out, the pull ring is pulled, and the connecting rope drives the locking hook to flip upward, so that the locking hook disengages from the locking rod. At this time, the feeding plate can be pulled out. At the same time, the self-locking device is unlocked directly by the pull ring driving the connecting rope, without the need for other linkage unlocking structures. The overall structure design is simple. Attached Figure Description

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A connecting rod 306 is fixedly connected to one side of the connecting block 305. A second planar gear 307 is fixedly connected to one side of the connecting rod 306.

[0027] In a preferred embodiment, an oven door 101 is provided on one side of the oven body 1, a transparent observation window 102 is fixedly connected inside the oven door 101, a support base plate 103 is fixedly connected to the bottom of the oven body 1, support feet 104 are fixedly connected around the bottom of the support base plate 103, a control panel 105 is fixedly connected to the top of one side of the oven body 1, a pressure relief device 106 is fixedly connected to the other side of the oven body 1, a temperature detection device 107 is fixedly connected to the top inside the oven body 1, and a support plate 108 is provided at the bottom of the feeding plate 4.

[0028] In a preferred embodiment, a retaining ring 403 is fixedly connected to one side of the feeding plate 4, a pull ring 401 is provided on one side of the retaining ring 403, a connecting rope 402 is fixedly connected to one side of the pull ring 401, a locking hook 406 is fixedly connected to one side of the connecting rope 402, a fixed base 404 is fixedly connected to one side of the locking hook 406, and a locking rod 405 is provided at the bottom of the fixed base 404.

[0029] Reference Figure 5The dual-axis motor 2 is installed on one side of the fixed frame 204. The output shaft of the dual-axis motor 2 is fixedly connected to the second bevel gear 202. When the machine starts, the output shaft drives the threaded rod 2031 to rotate, which in turn drives the movable block 205 to slide back and forth horizontally inside the fixed frame 204. The movable block 205 is fixedly connected to the connecting seat 206, so that the movable rod 207 slides back and forth horizontally with the movable block 205, thereby causing the door connecting plate 209 to open outward.

[0030] In this embodiment, it is necessary to specifically add that: the second bevel gear 202 meshes with the first planar gear 203, the fixed frame 204 has a movable groove inside, the movable block 205 moves in the movable groove inside the fixed frame 204 through the threaded rod 2031, the fixed frame 204 has movable grooves on both sides of the bottom, the connecting seat 206 moves in the movable grooves on both sides of the bottom of the fixed frame 204, and the connecting seat 206 is fixedly connected to the movable rod 207 through the fixing pin.

[0031] Reference Figure 7 The output shaft on the other side of the dual-axis motor 2 is fixedly connected to the first bevel gear 201. When the machine starts working, it drives the second planar gear 307 to rotate through its output shaft, causing the connecting block 305 to move along the axis of the connecting rod 306, so that the telescopic rod 304 repeatedly extends and retracts, driving the piston plate 303 to move in a straight line inside the piston tube 3, thereby drawing the hot airflow inside the pressure relief device 106 into the piston tube 3 and discharging it from the air outlet 302. Opening the door directly under high pressure may cause the oven door 101 to be damaged by excessive pressure. Opening the door after depressurization can protect the integrity of 101.

[0032] In this embodiment, it is necessary to add that: the second planar gear 307 meshes with the first bevel gear 201, the connecting pipe 301 is fixedly connected to the pressure relief device 106, and a sealing collar is provided at the connection between the piston tube 3 and the piston plate 303 to ensure that the gas in the piston tube 3 will not leak.

[0033] Reference Figure 4 The temperature detection device 107 can monitor the temperature inside the oven in real time and feed the data back to the control panel 105. When the temperature is higher than the setting of the control system, the control panel 105 controls the first bevel gear 201 on one side of the dual-axis motor 2 to release pressure and dissipate heat inside the oven body 1, thereby ensuring the working environment inside the oven body 1.

[0034] In this embodiment, it is necessary to specifically add that: the control panel 105 electrically controls the dual-axis motor 2, and the control panel 105 can independently control the start, stop and speed of the output shafts on the left and right sides of the dual-axis motor 2; the oven door connecting plate 209 is fixedly connected to the top of the oven door 101 by bolts; the guide plate 208 is fixedly connected to the top of the oven body 1; the top of the oven body 1 is provided with a placement groove; a sealing kit is provided at the contact point between the oven body 1 and the oven door 101; and the top of the support plate 108 is provided with protective texture.

[0035] Reference Figure 8 The locking hook 406 is set parallel to the side wall of the feeding plate 4, and has a notch at the lower end to accommodate the locking rod 405. The end is in an inclined triangular shape. A connecting rope 402 is fixedly connected between the pull ring 401 and the locking hook 406, and the connecting rope 402 passes through the retaining ring 403.

[0036] In this embodiment, it is necessary to specifically add that: the locking rod 405 is fixedly connected to the inner wall of the oven body 1, the connection between the fixed base 404 and the locking hook 406 is provided with a bearing, and the diameter of the pull ring 401 is larger than the inner diameter of the retaining ring 403.

[0037] The working principle of this invention is as follows: When using this equipment, after the material inside the oven body 1 has been processed, the pressure relief device 106 is opened, and the dual-axis motor 2 is turned on via the control panel 105. This causes the first bevel gear 201 on one side of the dual-axis motor 2 to rotate, thereby driving the second planar gear 307 to rotate via its output shaft during startup. This causes the connecting block 305 to move along the axis of the connecting rod 306, causing the telescopic rod 304 to repeatedly extend and retract. This drives the piston plate 303 to move linearly inside the piston tube 3, thereby drawing the hot airflow inside the pressure relief device 106 into the piston tube 3 and discharging it from the outlet 302. When the hot airflow inside the oven body 1 has been discharged to a certain extent, the dual-axis motor 2 is turned on via the control panel 105. The second bevel gear 202 on the other side of the machine 2 rotates, driving the threaded rod 2031 to rotate through its output shaft, which in turn drives the movable block 205 to slide back and forth horizontally inside the fixed frame 204. The movable block 205 is fixedly connected to the connecting seat 206, so that the movable rod 207 slides back and forth horizontally with the movable block 205, thereby causing the oven door connecting plate 209 to open outward. The temperature detection device 107 can monitor the temperature inside the oven body 1 in real time and feed the data back to the control panel 105. When the temperature is higher than the setting of the control system, the control panel 105 controls the first bevel gear 201 on one side of the dual-axis motor 2 to release pressure and dissipate heat inside the oven body 1, thereby ensuring the working environment inside the oven body 1.

[0038] When the feeding plate 4 needs to be pulled out, pull the ring 401, and the connecting rope 402 will cause the locking hook 406 to flip upward, so that the locking hook 406 disengages from the locking rod 405. At this time, the feeding plate 4 can be pulled out, and then the material on the top of the feeding plate 4 can be taken out. When the feeding plate 4 is pushed inward, since the lower end of the locking hook 406 is inclined triangular, the end of the locking hook 406 will flip upward when it touches the locking rod 405. After continuing to push inward, the locking hook 406 will flip downward, and the locking hook 406 and the locking rod 405 will lock together, and the feeding plate 4 will achieve self-locking.
