Description

Technical Field

[0001] The present invention relates to the technical field of automatic opening structures, and more particularly to an automatic opening structure for a chip packaging oven. Background Art

[0002] Chip packaging is an important link in semiconductor manufacturing. It involves placing a chip into a specific packaging structure to protect the chip and enable it to connect with other electronic components. During the packaging process, drying is a common technological step, aiming to remove moisture in the chip or packaging structure and improve the reliability and stability of the product. Drying is usually carried out in an oven. The oven is internally provided with a heater, and the heat energy generated by the heater causes the moisture to evaporate, thereby achieving the drying process of the chip. During the drying process, it is necessary to ensure that parameters such as temperature, humidity, and time in the oven are precisely controlled to ensure the consistency and reliability of the drying effect.

[0003] For the existing automatic opening structure of a chip packaging oven, workers usually need to manually open the oven to take out the packaged chips. However, when workers perform this operation, the high-temperature hot air flow inside the oven will quickly rush out. Since the temperature of these hot air flows is extremely high, they can easily cause serious burns to the skin of workers, not only threatening the safety and health of workers, but also potentially affecting 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 above-mentioned background art.

[0005] To achieve the above object, the present invention provides the following technical solution: An automatic opening structure for a chip packaging oven, including an oven main body. In the middle of the top of the oven main body, there is a double-shaft motor. On one side of the top of the oven main body, there is a piston tube. Inside the oven main body, there is a material placing plate. On one side of the double-shaft motor, there is a first bevel gear fixedly connected. On the other side of the double-shaft motor, there is a second bevel gear fixedly connected. On one side of the second bevel gear, there is a first flat gear. On one side of the first flat gear, there is a threaded rod fixedly connected. Outside the threaded rod, there is a fixed frame. Inside the fixed frame, there is a movable block. On one side of the movable block, there is a connecting seat fixedly connected. At the bottom of the connecting seat, there is a movable rod fixedly connected. Outside the movable rod, there is a guide plate. On one side of the guide plate, there is a box door connecting plate. On one side of the movable rod, there is a clamping block. Inside the box door connecting plate, there is a movable card slot opened. On one side of the piston tube, there is a connecting pipe. At the top of the piston tube, there is an air outlet fixedly connected. Inside the piston tube, there is a piston plate. On one side of the piston plate, there is a telescopic rod fixedly connected. On one side of the telescopic rod, there is a connecting block fixedly connected. On one side of the connecting block, there is a connecting rod fixedly connected. On one side of the connecting rod, there is a second flat gear fixedly connected.

[0006] Further, on one side of the oven main body, there is an oven door. Inside the oven door, there is a transparent observation window fixedly connected. At the bottom of the oven main body, there is a support bottom plate fixedly connected. Around the bottom of the support bottom plate, there are support feet fixedly connected. At the top of one side of the oven main body, there is a control panel fixedly connected. On the other side of the oven main body, there is a pressure relief device fixedly connected. At the top inside the oven main body, there is a temperature detection device fixedly connected. At the bottom of the material placing plate, there is a support plate.

[0007] Further, on one side of the material placing plate, there is a snap ring fixedly connected. On one side of the snap ring, there is a pull ring. On one side of the pull ring, there is a connecting rope fixedly connected. On one side of the connecting rope, there is a locking hook fixedly connected. On one side of the locking hook, there is a fixed base. At the bottom of the fixed base, there is a locking rod.

[0008] Further, the second bevel gear meshes with the first flat gear. Inside the fixed frame, there is an activity slot opened. The movable block moves in the activity slot opened inside the fixed frame through the threaded rod. On both sides of the bottom of the fixed frame, there are activity slots opened. The connecting seat moves in the activity slots opened on both sides of the bottom of the fixed frame. The connecting seat and the movable rod form a fixed connection through a fixed pin.

[0009] Further, the second flat gear meshes with the first bevel gear. The connecting pipe is fixedly connected with the pressure relief device.

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

[0011] Further, 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. The diameter of the pull ring is larger than the diameter inside the snap ring.

[0012] Technical effects and advantages of the present invention: 1. By providing an opening device, the present invention controls the rotation of the second bevel gear on the other side of the dual-axis motor through the control panel. The output shaft drives the threaded rod to rotate, thereby driving the movable block to slide back and forth horizontally inside the fixed frame. Since the movable block is fixedly connected to the connecting seat, the movable rod slides back and forth horizontally following the movable block, so that the door connecting plate opens outwards, which can effectively solve the technical problems such as inconvenience and low intelligence level caused by the need to manually pull the handle to operate the opening and closing of the box door in the prior art, thus realizing the automatic opening and closing function.

[0013] 2. By providing devices such as the movable rod, after the material processing inside the oven body is completed, the pressure relief device is opened, and at the same time, the control panel controls the dual-axis motor to start, so that the first bevel gear on one side of the dual-axis motor rotates. Thus, when starting to work, the output shaft drives the second flat gear to rotate, moving the connecting block along the axis of the connecting rod, causing the telescopic rod to repeatedly extend and retract, driving the piston plate to move linearly inside the piston tube, and then sucking the hot air flow inside the pressure relief device into the piston tube and discharging it from the air outlet, which can effectively solve the possibility that when opening the box door, the hot air flow at high temperature inside the oven will quickly gush out and scald the workers.

[0014] 3. By providing a self-locking device, when it is necessary to pull out the feeding plate, the pull ring is pulled, and the connecting rope drives the locking hook to flip upwards, 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 unlocking of the self-locking device directly uses the pull ring to drive the connecting rope to pull, without setting other interlocking unlocking structures, and the overall structure design is simple.

[0018] Refer to Figures 1 to 8, the present invention provides an automatic opening structure for a chip packaging oven, including an oven main body 1. In the middle of the top of the oven main body 1, there is a double-shaft motor 2. On one side of the top of the oven main body 1, there is a piston tube 3. Inside the oven main body 1, there is a material placing plate 4. On one side of the double-shaft motor 2, there is a first bevel gear 201 fixedly connected. On the other side of the double-shaft motor 2, there is a second bevel gear 202 fixedly connected. On one side of the second bevel gear 202, there is a first flat gear 203.

On the top of the piston tube 3, there is an air outlet 302 fixedly connected. Inside the piston tube 3, there is a piston plate 303. On one side of the piston plate 303, there is a telescopic rod 304 fixedly connected. On one side of the telescopic rod 304, there is a connecting block 305 fixedly connected. On one side of the connecting block 305, there is a connecting rod 306 fixedly connected. On one side of the connecting rod 306, there is a second flat gear 307 fixedly connected.

[0019] In a preferred embodiment, on one side of the oven main body 1, there is an oven door 101. Inside the oven door 101, there is a transparent observation window 102 fixedly connected. At the bottom of the oven main body 1, there is a support bottom plate 103 fixedly connected. Around the bottom of the support bottom plate 103, there are support feet 104 fixedly connected. On the top of one side of the oven main body 1, there is a control panel 105 fixedly connected. On the other side of the oven main body 1, there is a pressure relief device 106 fixedly connected. On the top inside the oven main body 1, there is a temperature detection device 107 fixedly connected. At the bottom of the material placing plate 4, there is a support plate 108.

[0020] In a preferred embodiment, on one side of the material placing plate 4, there is a snap ring 403 fixedly connected. On one side of the snap ring 403, there is a pull ring 401. On one side of the pull ring 401, there is a connecting rope 402 fixedly connected. On one side of the connecting rope 402, there is a locking hook 406 fixedly connected. On one side of the locking hook 406, there is a fixed base 404 fixedly connected. At the bottom of the fixed base 404, there is a locking rod 405.

[0021] Refer to Figure 5, the dual-axis motor 2 is installed on one side of the fixed frame 204. The output shaft on one side of the dual-axis motor 2 is fixedly connected to the second bevel gear 202. Thus, when the work starts, the output shaft drives the threaded rod 2031 to rotate, and then drives the movable block 205 to slide back and forth horizontally inside the fixed frame 204. Since the movable block 205 is fixedly connected to the connecting seat 206, the movable rod 207 slides back and forth horizontally following the movable block 205, so that the door connecting plate 209 opens outwards.

[0022] In this embodiment, it should be specifically supplemented that: the second bevel gear 202 meshes with the first flat gear 203. An activity slot is opened inside the fixed frame 204. The movable block 205 moves in the activity slot opened inside the fixed frame 204 through the threaded rod 2031. Activity slots are opened on both sides of the bottom of the fixed frame 204. The connecting seat 206 moves in the activity slots opened on both sides of the bottom of the fixed frame 204. The connecting seat 206 and the movable rod 207 form a fixed connection through a fixing pin.

[0023] Refer to 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 work starts, the output shaft drives the second flat gear 307 to rotate, moves the connecting block 305 along the axis of the connecting rod 306, makes the telescopic rod 304 extend and retract repeatedly, drives the piston plate 303 to move linearly inside the piston tube 3, and then inhales the hot air flow inside the pressure relief device 106 into the piston tube 3 and discharges it from the air outlet 302. Opening the door directly under high pressure may cause the oven door 101 to be damaged due to excessive pressure. Opening the door after pressure relief can protect the integrity of 101.

[0024] In this embodiment, it should be specifically supplemented that: the second flat gear 307 meshes with the first bevel gear 201. The connecting pipe 301 is fixedly connected to the pressure relief device 106. A sealing sleeve ring is provided at the connection between the piston tube 3 and the piston plate 303 to ensure that the gas inside the piston tube 3 does not leak.

[0025] Refer to Figure 4 , the temperature detection device 107 can monitor the temperature inside the oven in real time and feedback the data 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 relieve pressure and dissipate heat inside the oven main body 1, so as to ensure the working environment inside the oven main body 1.

[0026] In this embodiment, it should be specifically supplemented 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 both the left and right sides of the dual-axis motor 2. The door connecting plate 209 is fixedly connected to the top of the oven door 101 through bolts. The guide plate 208 is fixedly connected to the top of the oven body 1. A placement groove is provided at the top of the oven body 1. A sealing kit is provided at the contact between the oven body 1 and the oven door 101. Protective patterns are provided on the top of the support plate 108.

[0027] Referring to Figure 8 , the locking hook 406 is arranged parallel to the side wall of the material placing plate 4. The lower end has a notch for accommodating the locking rod 405, and 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 snap ring 403.

[0028] In this embodiment, it should be specifically supplemented that: the locking rod 405 is fixedly connected to the inner wall of the oven body 1. A bearing is provided at the connection between the fixed base 404 and the locking hook 406. The diameter of the pull ring 401 is larger than the inner diameter of the snap ring 403.

[0029] The working principle of the present invention: When using this device, after the materials inside the oven body 1 are processed, the pressure relief device 106 is opened, and at the same time, the control panel 105 controls the dual-axis motor 2 to start, so that the first bevel gear 201 on one side of the dual-axis motor 2 rotates. Thus, at the start of work, the output shaft drives the second planar gear 307 to rotate, moves the connecting block 305 along the axis of the connecting rod 306, makes the telescopic rod 304 repeatedly expand and contract, drives the piston plate 303 to move linearly inside the piston tube 3, and then inhales the hot air flow inside the pressure relief device 106 into the piston tube 3 and discharges it from the air outlet 302. When the hot air flow inside the oven body 1 is discharged to a certain extent, the control panel 105 controls the second bevel gear 202 on the other side of the dual-axis motor 2 to rotate, drives the threaded rod 2031 to rotate through its output shaft, and then drives the movable block 205 to slide back and forth horizontally inside the fixed frame 204. Since the movable block 205 is fixedly connected to the connecting seat 206, the movable rod 207 follows the movable block 205 to slide back and forth horizontally, so that the door connecting plate 209 is opened outwards. 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 set value of the control system, the control panel 105 controls the first bevel gear 201 on one side of the dual-axis motor 2 to relieve pressure and dissipate heat inside the oven body 1, so as to ensure the working environment inside the oven body 1.

[0030] When it is necessary to pull out the feeding plate 4, pull the pull ring 401, and the connecting rope 402 drives 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 end of the locking hook 406 is in an inclined triangular shape, the end of the locking hook 406 will flip upward when it touches the locking rod 405. After continuing to push inward, at this time the locking hook 406 flips downward, and the locking hook 406 and the locking rod 405 are engaged with each other, and the feeding plate 4 realizes self-locking.
