Description

Technical Field

[0001] This application relates to the field of substrate punching equipment technology, and in particular to an automatic substrate punching device. Background Technology

[0002] In modern industrial manufacturing, substrates are a crucial basic material for industries such as electronics, semiconductors, and new energy, and the quality of their initial processing and punching has a significant impact on subsequent processes. However, existing substrate punching equipment has obvious technical shortcomings when handling large-sized initial processing substrates.

[0003] In practical use, it was found that most equipment relies on manual operation in the substrate positioning process, requiring operators to manually place the substrate into the punching station. This is not only inefficient but also makes it difficult to guarantee the accuracy of positioning. Due to the lack of automatic positioning function, the equipment cannot automatically adjust the positioning according to different substrate lengths and dimensions, nor can it achieve automated connection from feeding to positioning, resulting in unstable positioning effects for different batches of substrates. Therefore, we propose an automatic substrate punching device to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies, such as the lack of automatic positioning function, the inability of equipment to automatically adjust positioning according to different substrate lengths, and the inability to achieve automated connection from feeding to positioning, resulting in unstable positioning effects for different batches of substrates. Therefore, an automatic substrate punching device is proposed.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: an automatic substrate punching device, including a base box, a protective shell fixedly installed on the top of the base box, an opening on the bottom right side of the protective shell, a support box slidably installed on the top of the base box, a seat hole on the top of the base box, a lead screw seat slidably installed in the seat hole, a transmission mechanism between the lead screw seat and the base box, the top of the lead screw seat being fixedly connected to the bottom of the support box, a movable hole on the lead screw seat, a rotating shaft rotatably installed on the bottom inner wall of the movable hole, the top end of the rotating shaft extending into the support box, a transmission mechanism between the rotating shaft and the base box, an observation window on the right side of the protective shell, the observation window being located above the opening; a bidirectional mechanism is provided inside the support box, baffles are fixedly installed on the front and rear sides of the top of the support box, a positioning mechanism is provided above the support box, a hydraulic cylinder is fixedly installed on the top of the protective shell, the bottom end of the hydraulic cylinder output shaft extends into the protective shell, a lifting plate is fixedly installed on the bottom end of the hydraulic cylinder output shaft, a mounting seat is fixedly installed on the bottom of the lifting plate, a punching mechanism is provided at the bottom of the mounting seat, and a controller is provided on the front side of the base box.

[0006] A further configuration of this application is as follows: the transmission mechanism includes a motor and a lead screw, the motor is fixedly installed on the right side of the base box, the lead screw is fixedly installed on the output shaft of the motor, the left end of the lead screw is rotatably connected to the inner wall of the left side of the base box, the lead screw seat is threaded on the lead screw, the movable hole is located above the lead screw, and the motor is electrically connected to the controller.

[0007] By adopting the above technical solution and by setting up a transmission mechanism, the motor can drive the lead screw to rotate, thereby enabling the lead screw seat to move left and right, and achieving the purpose of precise displacement control of the support box.

[0008] A further configuration of this application is as follows: the transmission mechanism includes a gear and a rack plate, a gear is fixedly sleeved on the rotating shaft, the gear is located in the movable hole, and the same rack plate is fixedly installed on the inner walls of both sides of the bottom box, the rack plate is located above the rear side of the lead screw, and the gear meshes with the rack plate.

[0009] By adopting the above technical solution and by setting up a transmission mechanism, the linear motion of the lead screw seat can be converted into the rotational motion of the shaft through the meshing of the gear and the rack plate when the lead screw seat moves left and right.

[0010] A further configuration of this application is as follows: the bidirectional mechanism includes a bidirectional screw and two screw seats. The same bidirectional screw is rotatably installed on the inner walls of both sides of the support box. Two screw seats are threaded onto the bidirectional screw. Connecting plates are fixedly installed on both sides of the screw seats. The ends of the two connecting plates that are far apart from each other extend to the outside of the support box. A fixing plate is fixedly installed on the top of the connecting plate. The fixing plate is located on the outside of the support box. A driving mechanism is provided between the bidirectional screw and the rotating shaft.

[0011] By adopting the above technical solution and by setting up a bidirectional mechanism, the bidirectional screw can drive the two screw seats to move closer or further apart, thereby driving the two connecting plates to move closer or further apart, and thus achieving the purpose of driving the two fixed plates to move closer or further apart.

[0012] A further feature of this application is that the driving mechanism includes two conical wheels, and conical wheels are fixedly sleeved on both the bidirectional screw and the top of the rotating shaft. The conical wheels are located between the two screw seats, and the two conical wheels mesh with each other.

[0013] By adopting the above technical solution and by setting up a drive mechanism, the rotating shaft can drive the bidirectional screw to rotate synchronously.

[0014] A further feature of this application is that the positioning mechanism includes two positioning seats and two positioning pads. Positioning seats are provided on the inner sides of both fixed plates, and positioning pads are provided on the adjacent sides of the two positioning seats. A buffer mechanism is provided between the positioning seats and the fixed plates.

[0015] By adopting the above technical solution and by setting up a positioning mechanism, when the two positioning seats are close to each other, they can contact the substrate through the positioning pad, thereby achieving the purpose of clamping and positioning the substrate.

[0016] A further feature of this application is that the buffer mechanism includes a slide rod and a spring.

A spring is sleeved on the slide rod, and both ends of the spring are fixedly connected to the inside of the fixed plate and the outside of the positioning seat, respectively.

[0017] By adopting the above technical solution and setting a buffer mechanism, when the positioning pad contacts the substrate, the slide rod slides along the fixed plate and compresses the spring. The spring force makes the positioning pad fit tightly against both sides of the substrate, which can achieve adaptive clamping and positioning of substrates of different lengths. The buffering effect avoids rigid contact damage to the edge of the substrate and ensures the positional stability of the substrate during punching.

[0018] A further provision of this application is that the punching mechanism includes a mounting plate and a punching die, the mounting plate is fixedly mounted on the bottom of the mounting base through a detachable structure, and the punching die is fixedly mounted on the bottom of the mounting plate.

[0019] By adopting the above technical solution and by setting up a punching mechanism, the hydraulic cylinder output shaft drives the lifting plate, mounting base and punching die to move down quickly with stable pressure, so as to achieve the purpose of punching the substrate by cooperating with the top of the support box.

[0020] The beneficial effects of this application are:

[0021] (1) Through the cooperation of motor, lead screw, lead screw seat and support box, the motor can drive the support box to move left and right, which can ensure that the substrate can be accurately delivered to the punching station and avoid punching scrap due to position deviation. At the same time, it can facilitate the operator to take out the punched finished product and waste from the top of the support box, thereby greatly improving production efficiency.

[0022] (2) Through the cooperation of the rotating shaft, gear, rack plate, conical wheel, double screw, screw seat, connecting plate, fixed plate, slide rod, spring, positioning seat and positioning pad, the linear motion of the screw seat can be converted into the rotational motion of the rotating shaft, which can drive the double screw to rotate, drive the positioning seat to move closer to the substrate, and make contact with the substrate through the positioning pad on the inner side of the positioning seat. The slide rod slides along the fixed plate and compresses the spring. The elastic force of the spring makes the positioning pad tightly fit the two sides of the substrate, which can realize the adaptive clamping and positioning of substrates of different lengths. It also avoids damage to the edge of the substrate by rigid contact through the buffering effect, and ensures the positional stability of the substrate during punching. Attached Figure Description

The gear 402 and the rack plate 403 mesh with each other.

[0033] Specifically, the bidirectional mechanism includes a bidirectional screw 302 and two screw seats 303. The same bidirectional screw 302 is rotatably installed on the inner walls of both sides of the support box 3. Two screw seats 303 are threaded on the bidirectional screw 302. Connecting plates 304 are fixedly installed on both sides of the screw seats 303. The ends of the two connecting plates 304 that are far apart from each other extend to the outside of the support box 3. A fixing plate 5 is fixedly installed on the top of the connecting plate 304. The fixing plate 5 is located on the outside of the support box 3. A drive mechanism is provided between the bidirectional screw 302 and the rotating shaft 401.

[0034] Specifically, the drive mechanism includes two conical wheels 9. Conical wheels 9 are fixedly sleeved on both the bidirectional screw 302 and the top of the rotating shaft 401. The conical wheels 9 are located between the two screw seats 303, and the two conical wheels 9 mesh with each other.

[0035] Specifically, the positioning mechanism includes two positioning seats 6 and two positioning pads. Positioning seats 6 are provided on the inner side of both fixing plates 5, and positioning pads are provided on the adjacent side of the two positioning seats 6. A buffer mechanism is provided between the positioning seats 6 and the fixing plates 5.

[0036] Specifically, the buffer mechanism includes a slide rod 501 and a spring 502. The slide rod 501 is slidably mounted on the fixed plate 5. One end of the slide rod 501 extends to the outside of the fixed plate 5, and the other end of the slide rod 501 is fixedly connected to the outside of the corresponding positioning seat 6. The spring 502 is sleeved on the slide rod 501, and both ends of the spring 502 are fixedly connected to the inside of the fixed plate 5 and the outside of the positioning seat 6, respectively.

[0037] Specifically, the punching mechanism includes a mounting plate 703 and a punching die 704. The mounting plate 703 is fixedly mounted on the bottom of the mounting base 702 through a detachable structure, and the punching die 704 is fixedly mounted on the bottom of the mounting plate 703.

[0038] In this application, when punching a substrate of a standard size (300mm in length and 150mm in width), the operator first places the substrate between two baffles 301 on the top of the support box 3. The baffles 301 initially limit the substrate in the front-back direction to prevent it from sliding back and forth during the movement of the support box 3, laying the foundation for subsequent precise positioning. Then, the punching parameters are set by the controller 8, and the controller 8 sends a command to start the motor 101. The output shaft of the motor 101 drives the lead screw 103 to rotate. Since the lead screw seat 104 is threadedly connected to the lead screw 103 and is limited by the seat hole 102, the lead screw seat 104 moves horizontally along the lead screw 103, thereby driving the support box 3 to move smoothly into the protective shell 2. This enables precise displacement control of the support box 3, ensuring that the substrate can be accurately delivered to the punching station and avoiding the purpose of punching scrap due to positional deviation.

[0039] During the movement of the support box 3, the rotating shaft 401 moves synchronously with the lead screw seat 104. The gear 402 fixed on it meshes with the fixed rack plate 403 to generate rotation, which can convert the linear motion of the lead screw seat 104 into the rotational motion of the rotating shaft 401. The conical wheel 9 at the top of the rotating shaft 401 meshes with the conical wheel 9 on the bidirectional screw 302 to realize the vertical conversion of the motion direction, which can drive the bidirectional screw 302 to rotate. The positive and negative threads of the bidirectional screw 302 drive the two screw seats 303 to approach each other. Through the connecting plate 304, the fixed plate 5 and the positioning seat 6 are pulled closer to the substrate. The positioning pad inside the positioning seat 6 can contact the substrate. The slide bar 501 slides along the fixed plate 5 and compresses the spring 502. The elastic force of the spring 502 makes the positioning pad tightly fit the two sides of the substrate, which can realize the adaptive clamping and positioning of substrates of different lengths. It also avoids damage to the edge of the substrate by rigid contact through the buffering effect, and ensures the positional stability of the substrate during punching.

[0040] When the support box 3 carries the substrate fully into the protective shell 2 and reaches the punching station, the controller 8 receives the position sensor signal and controls the motor 101 to pause. At the same time, the hydraulic cylinder 7 is started. The output shaft of the hydraulic cylinder 7 drives the lifting plate 701, the mounting seat 702 and the punching die 704 to descend quickly with stable pressure. This enables the punching die 704 to cooperate with the top of the support box 3 to complete the substrate punching operation. During the punching process, the protective shell 2 can effectively block the flying debris, and the observation window 202 facilitates real-time monitoring of the punching status. After the punching is completed, the output shaft of the hydraulic cylinder 7 retracts and resets, and the motor 101 reverses to drive the support box 3 to return along the original path. At this time, the gear 402 rotates in the opposite direction, causing the bidirectional screw 302 to drive the positioning seat 6 to release the substrate. This allows the operator to easily remove the punched finished product and waste from the top of the support box 3, thereby greatly improving production efficiency. Furthermore, the detachable mounting plate 703 allows for quick replacement of punching dies 704 of different specifications to meet the punching needs of various substrates and enhance the equipment's versatility.
