Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically an automatic material feeding mechanism for a hot press. Background Technology

[0002] Automatic feeding mechanisms can be used for circuit board feeding. The significance of hot pressing circuit boards is that the hot press applies heat and pressure to make the components on the circuit board tightly bonded to the inner circuit board, thereby enhancing the overall mechanical strength and electrical connection reliability of the circuit board. However, existing devices have certain drawbacks. For example, the hot press with automatic feeding described in announcement number CN221818941U includes a base, a connecting frame on the top left side of the base, a motor on the front right side of the connecting frame, a rotating rod on the left side of the inner cavity of the connecting frame, four threaded rods on the top right side of the base, a fixing plate on the four threaded rods, and a first fixing sleeve and a second fixing sleeve threadedly connected to the four threaded rods near the top and bottom of the fixing plate, respectively.

[0003] Although the above-mentioned device can automatically feed materials into the hot press, when used for hot pressing of circuit boards, the circuit boards still need to be placed onto the conveyor belt manually. This still requires continuous manual feeding, which increases the labor intensity of workers and makes the device inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding mechanism for a hot press to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic feeding mechanism for a hot press includes a base, a limit rail fixedly connected to the upper surface of the base, a lifting seat fixedly connected to the inner bottom surface of the base, a second stepper motor fixedly connected to the upper surface of the lifting seat, and a second lead screw fixedly connected to the output end of the second stepper motor.

[0007] The inner surface of the limiting rail is provided with a conveying module. The conveying module includes a sliding plate, a rotating roller and a mounting plate. The sliding plate is slidably connected to the inside of the limiting rail. The mounting plate is embedded and movably connected to the inner surface of the sliding plate. The outer surface of the mounting plate is fixedly connected with a guide post. The rotating roller is rotatably connected to the inner surface of the mounting plate. There are two rotating rollers on a single mounting plate. The outer surface of the rotating roller is connected to a conveyor belt.

[0008] An adsorption module is slidably connected to the outer surface of the lifting seat. The adsorption module includes a connecting plate and a rubber piston. The connecting plate is slidably connected to the rear surface of the lifting seat. A sealing cylinder is fixedly connected to the upper surface of the connecting plate. The rubber piston is movably connected to the inside of the sealing cylinder. A frame is fixedly connected to the upper surface of the rubber piston.

[0009] Furthermore, the upper surface of the base is provided with a mounting hole, and a first electric push rod is fixedly connected to the upper surface of the base. The output end of the first electric push rod is fixedly connected to a connecting frame.

[0010] Furthermore, a first stepper motor is fixedly connected to the outer surface of the mounting plate, and a hexagonal column is fixedly connected to the output end of the first stepper motor. The hexagonal column passes through two rotating rollers, and the connecting frame and the hexagonal column are rotatably connected.

[0011] Furthermore, a limiting groove is formed on the outer surface of the sliding plate, and the limiting groove and the limiting rail are slidably connected.

[0012] Furthermore, a double-ended lead screw is threadedly connected to the lower surface of the sliding plate, and a handwheel is fixedly connected to one end of the double-ended lead screw.

[0013] Furthermore, the upper bottom surface of the lifting seat is provided with a sliding groove, a slider is slidably connected inside the sliding groove, a bolt is threadedly connected to the upper surface of the slider, a groove is provided on the front surface of the lifting seat, and a limit rod is fixedly connected to the inner surface of the lifting seat.

[0014] Furthermore, the adsorption module also includes a sliding plate, a second electric push rod, and a suction cup. The sliding plate is slidably connected to the outer surface of the limiting vertical rod. The sliding plate and the second lead screw are threaded together. The second electric push rod is fixedly connected to the upper surface of the connecting plate and the frame. The suction cup is fixedly connected to the lower end of the sealing cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. For the problem of needing to adjust the spacing between two conveyor belts to adapt to circuit boards of different specifications, the double-ended screw is rotated by handwheel. Under the push of the screw, the two mounting plates move inward or outward. The guide post passes through the sliding plate to guide the sliding of the mounting plates.

[0017] 2. Driven by the screw thread, the sliding plate and the connecting plate rise or fall. When the suction cup contacts the circuit board, the second electric push rod is activated. The second electric push rod, in conjunction with the frame, drives the rubber piston to rise, causing the suction cup to start working and adsorb the circuit board. After the connecting plate rises, the first electric push rod is activated. Driven by the first electric push rod, the mounting plate moves towards the suction cup position, making it easier for the suction cup to place the circuit board onto the conveyor belt. No manual feeding is required, reducing the labor intensity of workers and facilitating the use of the device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4In this embodiment of the utility model, an automatic feeding mechanism for a hot press includes a base 1, a limit rail 102 fixedly connected to the upper surface of the base 1, a lifting seat 4 fixedly connected to the inner bottom surface of the base 1, a second stepper motor 405 fixedly connected to the upper surface of the lifting seat 4, and a second lead screw 406 fixedly connected to the output end of the second stepper motor 405.

[0025] The inner surface of the limiting rail 102 is provided with a conveying module 2. The conveying module 2 includes a sliding plate 201, a rotating roller 205 and a mounting plate 203. The sliding plate 201 is slidably connected to the inside of the limiting rail 102. The mounting plate 203 is embedded and movably connected to the inner surface of the sliding plate 201. The outer surface of the mounting plate 203 is fixedly connected with a guide post 204. The rotating roller 205 is rotatably connected to the inner surface of the mounting plate 203. There are two rotating rollers 205 on a single mounting plate 203. The outer surface of the rotating roller 205 is connected to a conveyor belt 206.

[0026] An adsorption module 5 is slidably connected to the outer surface of the lifting seat 4. The adsorption module 5 includes a connecting plate 501 and a rubber piston 504. The connecting plate 501 is slidably connected to the rear surface of the lifting seat 4. A sealing cylinder 503 is fixedly connected to the upper surface of the connecting plate 501. The rubber piston 504 is movably connected to the inside of the sealing cylinder 503. A frame 505 is fixedly connected to the upper surface of the rubber piston 504.

[0027] Specifically, to address the issue of adjusting the spacing between the two conveyor belts 206 to accommodate circuit boards of different specifications, the double-ended lead screw 3 is rotated via handwheel 301. Driven by the thread, the two mounting plates 203 move inward or outward. The guide post 204, passing through the sliding plate 201, guides the sliding of the mounting plates 203. The second stepper motor 405 is then activated. The output of the second stepper motor 405 drives the second lead screw 406 to rotate. The second stepper motor 405 is connected to an external reversing switch. Therefore, driven by the thread, the slide plate 502 and the drive... When the connecting plate 501 rises or falls, and the suction cup 507 contacts the circuit board, the second electric push rod 506 is activated. The second electric push rod 506, in conjunction with the frame 505, drives the rubber piston 504 to rise, causing the suction cup 507 to start working and adsorb the circuit board. After the connecting plate 501 rises, the first electric push rod 103 is activated. Under the push of the first electric push rod 103, the mounting plate 203 moves towards the position of the suction cup 507, making it easier for the suction cup 507 to place the circuit board onto the conveyor belt 206. No manual feeding is required, reducing the labor intensity of workers.

[0028] Example 1

[0029] like Figure 1-4As shown, the upper surface of the base 1 has a mounting hole 101. A first electric push rod 103 is fixedly connected to the upper surface of the base 1. A connecting frame 104 is fixedly connected to the output end of the first electric push rod 103. A first stepper motor 207 is fixedly connected to the outer surface of the mounting plate 203. A hexagonal column 208 is fixedly connected to the output end of the first stepper motor 207. The hexagonal column 208 passes through two rotating rollers 205. The connecting frame 104 and the hexagonal column 208 are rotatably connected. A limit groove 202 is opened on the outer surface of the sliding plate 201. The limit groove 202 and the limit rail 102 are slidably connected. A double-ended lead screw 3 is threadedly connected to the lower surface of the sliding plate 201. A handwheel 301 is fixedly connected to one end of the double-ended lead screw 3.

[0030] In this embodiment, the base 1 is connected to the ground through the mounting hole 101 and the threaded assembly, and the limiting rail 102 overlaps with the hot press body 6. When the first electric push rod 103 is activated, the output end of the first electric push rod 103 retracts and engages with the connecting frame 104 to drive the hexagonal column 208 to move, so that the sliding plate 201 slides with the limiting groove 202 and the matching limiting rail 102. When the sliding plate 201 approaches the hot press body 6, the first stepper motor 207 is activated. The output end of the first stepper motor 207 engages with the hexagonal column 208 to drive the rotating roller 205 to rotate, so that the conveyor belt 206 transports the circuit board to the hot press body 6. At the same time, without the obstruction of the conveyor belt 206, it is easy for the connecting plate 501 to descend so that the suction cup 507 and the circuit boards stacked on the lifting seat 4 can contact each other, which is convenient for automatic feeding later.

[0031] To address the issue of adjusting the spacing between the two conveyor belts 206 to accommodate circuit boards of different specifications, the double-ended lead screw 3 is rotated via the handwheel 301. Under the push of the thread, the two mounting plates 203 move inward or outward, and the guide post 204 guides the sliding of the mounting plates 203 through the sliding plate 201.

[0032] Example 2

[0033] Based on Example 1, in order to overcome the problem that it is inconvenient to automatically feed the conveyor belt 206 in Example 1.

[0034] like Figure 1-4 As shown, the upper bottom surface of the lifting seat 4 is provided with a sliding groove 401, the sliding groove 401 is slidably connected to a slider 402, the upper surface of the slider 402 is threadedly connected to a bolt 403, the front surface of the lifting seat 4 is provided with a groove 404, and the inner surface of the lifting seat 4 is fixedly connected to a limit rod 407.

[0035] In this embodiment, the bolt 403 is manually rotated so that one end of the bolt 403 is separated from the lifting seat 4 by the push of the thread. Then, the slider 402 can be manually slid along the slide groove 401 so that the slider 402 limits the stacked circuit boards. The groove 404 is used for the connecting plate 501 to pass through the lifting seat 4 and connect with the slide plate 502. The limiting vertical rod 407 limits the lifting of the slide plate 502.

[0036] like Figure 1-4 As shown, the adsorption module 5 also includes a slide plate 502, a second electric push rod 506, and a suction cup 507. The slide plate 502 is slidably connected to the outer surface of the limiting vertical rod 407. The slide plate 502 is threadedly connected to the second lead screw 406. The second electric push rod 506 is fixedly connected to the upper surface of the connecting plate 501. The second electric push rod 506 is fixedly connected to the frame 505. The suction cup 507 is fixedly connected to the lower end of the sealing cylinder 503.

[0037] In this embodiment, the second stepper motor 405 is started, and the output end of the second stepper motor 405 drives the second lead screw 406 to rotate. The second stepper motor 405 is connected to an external reversing switch. Therefore, under the push of the screw, the slide plate 502 and the connecting plate 501 rise or fall. When the suction cup 507 contacts the circuit board, the second electric push rod 506 is started. The second electric push rod 506, together with the frame 505, drives the rubber piston 504 to rise, so that the suction cup 507 starts to work and adsorbs the circuit board. After the connecting plate 501 rises, the first electric push rod 103 is started. Under the push of the first electric push rod 103, the mounting plate 203 moves towards the position of the suction cup 507, so that the suction cup 507 can place the circuit board onto the conveyor belt 206 without manual loading, reducing the labor intensity of workers.
