Description

Technical Field

[0001] This invention relates to the field of automated processing equipment technology, specifically to an auxiliary material handling device for an automatic foam laminating machine. Background Technology

[0002] Automatic foam laminating machines are widely used in the electronics manufacturing industry to laminate foam materials to the surfaces of products such as screens and back panels. During the lamination process, operators need to manually place the foam material on the material handling station of the laminating machine, and then manually remove the finished product after lamination is complete. Currently, manual material handling is often too slow to match the high-speed operation of the equipment, which limits production efficiency. Furthermore, the positioning accuracy of operators when placing foam relies on personal experience, and positional deviations can lead to bonding misalignment, negatively impacting product quality. In addition, existing equipment generally lacks self-inspection capabilities for foam orientation; when foam is placed incorrectly, the equipment struggles to identify it, potentially resulting in defective products and material waste. To address these issues, some existing technologies employ vision inspection systems to identify foam orientation. However, vision systems typically require industrial cameras, light sources, industrial computers, and image processing algorithms, making them costly and susceptible to interference from ambient light and dust, and requiring complex maintenance. Therefore, we propose an auxiliary material handling device for an automatic foam bonding machine. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides an auxiliary material handling device for an automatic foam laminating machine, comprising a frame disposed on one side of the automatic foam laminating machine. The frame is equipped with a feeding module, a material handling robot, and a control unit. The feeding module temporarily stores and supplies the foam material to be laminated. The material handling robot includes an X-axis linear module, a Y-axis linear module, and a Z-axis lifting module. A gravity pendulum-type anti-foolproof material handling head is installed at the end of the Z-axis lifting module, used to pick up the foam material and simultaneously detect the positive and negative orientation of the foam material. The gravity pendulum-type foolproof material handling head includes a connecting base fixedly connected to the Z-axis lifting module. A pendulum shaft is fixedly installed on the connecting base. A pendulum assembly is arranged below the connecting base. The pendulum assembly includes a swing arm and a suction cup mounting base fixed to the lower end of the swing arm. The upper end of the swing arm is rotatably sleeved on the swing shaft, allowing the pendulum assembly to swing freely around the swing shaft. The suction cup mounting base is provided with at least one vacuum suction cup for picking up foam material. The center of gravity of the pendulum assembly is offset from the axis of the swing shaft in the horizontal direction, forming an eccentric structure. A micro switch is installed on the connecting base. The micro switch has a contact facing the side of the swing arm. The control unit is electrically connected to the feeding module, the picking and placing robot, and the gravity pendulum-type foolproof material handling head, and determines whether the orientation of the foam material is correct based on the electrical state of the micro switch.

[0004] In some embodiments, the feeding module includes a storage box mounted on a frame for stacking foam materials. The storage box has a discharge port and a pushing mechanism, which are located on opposite sides of the storage box for pushing the foam in the storage box out of the discharge port. A material picking transition platform is provided on the opposite side of the discharge port of the storage box for receiving the foam pushed out by the pushing mechanism. The material picking transition platform has a material picking positioning groove, the position of which corresponds to the picking path of the gravity pendulum type foolproof picking head.

[0005] In some embodiments, when the pendulum assembly is not picking up foam material, it naturally hangs down to a preset initial position under the action of gravity. When the pendulum assembly is in the initial position, the side of the swing arm contacts the contact of the micro switch, so that the micro switch is in a first electrical state. When the pendulum assembly deflects around the pendulum axis by more than a preset angle, the side of the swing arm separates from the contact, so that the micro switch switches to a second electrical state. The control unit determines whether the direction of the foam material is correct according to the first or second electrical state of the micro switch, and controls the action of the pushing mechanism or issues an alarm signal according to the determination result.

[0006] In some embodiments, an adjustable limiting baffle is provided at the discharge port of the storage box. The gap between the limiting baffle and the discharge port is matched with the thickness of a single piece of foam, which is used to limit only one piece of foam to pass through at a time.

[0007] In some embodiments, a guide rib is provided on the inner wall of the storage box. The guide rib extends along the height direction of the storage box, and the shape of the guide rib matches the process notch on the foam material to limit the placement direction of the foam material in the storage box.

[0008] In some embodiments, the pushing mechanism includes a pusher cylinder and a pusher plate, wherein the pusher plate is fixed to the end of the piston rod of the pusher cylinder.

[0009] In some embodiments, the control unit is configured with a feeding timing control module, which controls the pushing mechanism to perform a pushing action after the gravity pendulum-type foolproof picking head moves away from the picking transition platform, and sends a picking signal after the pushing is completed.

[0010] In some embodiments, the pendulum assembly further includes a counterweight block that can be moved and adjusted along the length of the pendulum arm and fixed on the pendulum arm. By adjusting the position of the counterweight block on the pendulum arm, the horizontal eccentricity between the center of gravity of the pendulum assembly and the pendulum axis can be changed, thereby adjusting the detection sensitivity of the pendulum assembly to the directional deviation of the foam material.

[0011] In some embodiments, a vacuum solenoid valve is provided in the air path of the vacuum suction cup, and the vacuum solenoid valve is electrically connected to the control unit.

[0012] In some embodiments, when the control unit determines that the direction of the foam material is incorrect based on the second electrical state of the micro switch, the control unit controls the vacuum solenoid valve to cut off the vacuum supply to the vacuum suction cup, causing the vacuum suction cup to release the foam material, and simultaneously controls the feeding mechanism to suspend feeding and controls the sound and light alarm to issue an alarm signal.

[0013] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an auxiliary material handling device for an automatic foam bonding machine, which has the following beneficial effects: 1. This invention employs a gravity pendulum-type foolproof pick-up head, utilizing the asymmetrical structure of the front and back of the foam material. The eccentric structure of the pendulum assembly responds to differences in the weight distribution of the foam, achieving automatic detection of the foam's orientation. When the foam is correctly oriented, the pendulum remains balanced, and the microswitch is closed. When the foam is reversed, the pendulum deflects, the microswitch opens, and the control unit determines the incorrect orientation and controls the vacuum solenoid valve to cut off the negative pressure supply to the vacuum suction cup, causing the incorrect foam to fall off naturally. Simultaneously, the feeding is paused, and an alarm is issued. This mechanical detection method eliminates the need for industrial cameras, light sources, and image processing algorithms, significantly reducing costs. It is also unaffected by ambient light and dust, simplifying maintenance. Furthermore, the pendulum assembly features an adjustable counterweight; adjusting its position changes the detection sensitivity. The same pick-up head can accommodate foam materials of different specifications and weights, eliminating the need for hardware replacement during model changes and making adjustments convenient.

[0014] 2. This invention achieves automatic foam feeding by setting up a storage box, a pushing mechanism, and a picking transition platform. Operators only need to put the foam into the storage box in batches, and the equipment can automatically complete the single-sheet feeding and push the foam to the designated position for the picking head to pick up. This reduces the manual operation of placing each piece individually, and operators do not need to frequently stand by the equipment, thus improving production efficiency. At the same time, the guide ribs set in the storage box can perform pre-inspection when the operator loads the foam. Only foam with the correct orientation can be put into the storage box, reducing the occurrence of orientation errors from the loading stage. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-6 This invention provides a technical solution: an auxiliary material handling device for an automatic foam bonding machine, comprising a frame 1, which is disposed on one side of the automatic foam bonding machine 21. The frame 1 is equipped with a feeding module 22, a material handling robot 23, and a control unit 2. The feeding module 22 is used to temporarily store and supply the foam material to be bonded. The material handling robot 23 includes an X-axis linear module 10, a Y-axis linear module 9, and a Z-axis lifting module 11. A gravity pendulum-type anti-foolproof material handling head 24 is installed at the end of the Z-axis lifting module 11 for picking up the foam material and simultaneously detecting the positive and negative directions of the foam material. The gravity pendulum-type anti-foolproof material handling head 24 includes a connecting seat 12 fixedly connected to the Z-axis lifting module 11. A pendulum shaft 13 is fixedly installed on the connecting seat 12. A pendulum assembly is disposed below the connecting seat 12, and the pendulum assembly includes a pendulum arm 14 and... A suction cup mounting base 15 is fixed to the lower end of the swing arm 14. The upper end of the swing arm 14 is rotatably sleeved on the swing shaft 13, allowing the pendulum assembly to swing freely around the swing shaft 13. The suction cup mounting base 15 is provided with at least one vacuum suction cup 19 for picking up foam material. The center of gravity of the pendulum assembly is offset from the axis of the swing shaft 13 in the horizontal direction, forming an eccentric structure. A micro switch 17 is installed on the connecting base 12. The micro switch 17 has a contact 18 facing the side of the swing arm 14. The control unit 2 is electrically connected to the feeding module 22, the picking and unloading robot 23, and the gravity pendulum-type foolproof picking head 24, and determines whether the direction of the foam material is correct according to the electrical state of the micro switch 17. When the picking head is working, the Z-axis lifting module 11 drives the picking head to descend, and the vacuum suction cup 19 contacts the foam surface and generates negative pressure to suck up the foam. Because the center of gravity of the pendulum assembly is off-center from the pendulum axis 13, when the foam is in the correct direction, the weight distribution of the foam itself matches the eccentric structure of the pendulum, and the pendulum maintains a balanced state. The side of the swing arm 14 is in contact with the contact 18 of the micro switch 17. When the foam is in the wrong direction, the weight distribution of the foam changes, and after being superimposed with the eccentric structure of the pendulum, a torque is generated, which forces the pendulum to deflect around the pendulum axis 13. The side of the swing arm 14 separates from the contact 18 of the micro switch 17, and the electrical state of the micro switch 17 changes accordingly. The control unit 2 determines whether the foam is in the correct direction based on this change.

[0020] The feeding module 22 includes a storage box 3 mounted on the frame 1 for stacking foam materials. The storage box 3 has a discharge port and a pushing mechanism, which are located on both sides of the storage box 3. The storage box 3 is used to push the foam in the storage box 3 out of the discharge port. A picking transition platform 4 is provided on the opposite side of the discharge port of the storage box 3 to receive the foam pushed out by the pushing mechanism. The picking transition platform 4 has a picking positioning groove. The position of the picking positioning groove corresponds to the picking path of the gravity pendulum type foolproof picking head 24. After the operator puts the stacked foam into the storage box 3, the pushing mechanism is started. The push rod cylinder 8 extends and drives the push plate 7 to push the bottom piece of foam out of the discharge port. The foam is pushed into the picking positioning groove of the picking transition platform 4. The outline of the picking positioning groove matches the shape of the foam, which can limit the foam to a preset position and ensure that the picking head can pick up the foam at the same position every time, avoiding picking failure due to position deviation.

[0021] When the pendulum assembly is not picking up foam material, it naturally hangs down to a preset initial position under the action of gravity. When the pendulum assembly is in the initial position, the side of the swing arm 14 contacts the contact 18 of the micro switch 17, putting the micro switch 17 in a first electrical state. When the pendulum assembly deflects around the pendulum axis 13 beyond a preset angle, the side of the swing arm 14 separates from the contact 18, causing the micro switch 17 to switch to a second electrical state. The control unit 2 determines the foam material based on the first or second electrical state of the micro switch 17. The control unit 2 determines whether the material orientation is correct and controls the feeding mechanism or issues an alarm signal based on the judgment result. When the feeding head is unloaded, the pendulum assembly hangs naturally under its own weight, and the side of the swing arm 14 presses against the contact 18 of the micro switch 17. At this time, the micro switch 17 is in the closed state, i.e., the first electrical state. After the feeding head picks up the foam, if the foam orientation is correct, the pendulum remains near its initial position, the micro switch 17 remains closed, the control unit 2 determines that the orientation is correct, and the robot continues to move the foam to the bonding station. If the foam orientation is incorrect, the pendulum deflects, the side of the swing arm 14 separates from the contact 18, the micro switch 17 switches to the open state, i.e., the second electrical state, the control unit 2 determines that the orientation is incorrect, immediately issues an alarm signal, and controls the feeding mechanism to stop feeding, waiting for the operator to handle the situation.

[0022] An adjustable limiting baffle 5 is provided at the discharge port of the storage box 3. The gap between the limiting baffle 5 and the discharge port matches the thickness of a single piece of foam, which is used to limit only one piece of foam to pass through at a time. A guide rib 6 is provided on the inner wall of the storage box 3. The guide rib 6 extends along the height direction of the storage box 3. The shape of the guide rib 6 matches the process notch on the foam material, which is used to limit the insertion direction of the foam material in the storage box 3. The pushing mechanism includes a push rod cylinder 8 and a push plate 7. The push plate 7 is fixed to the end of the piston rod of the push rod cylinder 8. The gap between the limiting baffle 5 and the discharge port is adjusted to be slightly larger than that of a single piece of foam. The thickness is such that when the pushing mechanism is activated, only the bottom foam piece can pass through the gap, while the upper foam pieces are blocked by the baffle, thus preventing multiple foam pieces from sticking together and being pushed out at the same time. The shape of the guide rib 6 corresponds to the process notch on the foam. When the operator loads the material, only foam with the correct orientation can be smoothly placed into the storage box 3 along the rib. If the foam is placed in the wrong orientation, the process notch position will not match, and the foam cannot be placed in. This plays a foolproof role in the loading process. When pushing the material, the push rod cylinder 8 extends and drives the push plate 7 to push the foam out. The push plate 7 has a large contact area with the foam, and the pushing process is relatively stable.

[0023] Example 2: Please refer to Figure 2-6 The control unit 2 is equipped with a feeding timing control module. The feeding timing control module controls the pushing mechanism to perform the pushing action after the gravity pendulum-type foolproof picking head 24 moves away from the picking transition platform 4. After the pushing is completed, the module sends a picking signal. The feeding timing control module is responsible for coordinating the order of feeding and picking actions. Only after the picking head takes the foam off the picking transition platform 4 and moves away will the control module send a command to the pushing mechanism to perform the next pushing action, pushing the new foam to the picking transition platform 4. After the pushing is completed, the control module sends a picking signal to notify the picking head to pick up the material. This staggered timing can avoid collisions when pushing and picking are performed simultaneously.

[0024] The pendulum assembly also includes a counterweight 16, which can be moved and adjusted along the length of the pendulum arm 14 and fixed on the pendulum arm 14. By adjusting the position of the counterweight 16 on the pendulum arm 14, the horizontal eccentricity between the center of gravity of the pendulum assembly and the pendulum axis 13 can be changed, thereby adjusting the detection sensitivity of the pendulum assembly to the directional deviation of the foam material. The position of the counterweight 16 on the pendulum arm 14 can be adjusted. When the counterweight 16 moves upward, the center of gravity of the pendulum assembly is closer to the pendulum axis 13, the eccentricity becomes smaller, and the pendulum is more sensitive to changes in the weight of the foam, which is suitable for detecting lighter foam. When the counterweight 16 moves downward, the eccentricity becomes larger, the torque generated by the pendulum itself is greater, the detection threshold is increased, which is suitable for detecting heavier foam. By adjusting the position of the counterweight 16, the same set of pick-up heads can be adapted to different specifications of foam materials without replacing the hardware.

[0025] A vacuum solenoid valve 20 is installed in the air circuit of the vacuum suction cup 19. The vacuum solenoid valve 20 is electrically connected to the control unit 2. When the control unit 2 determines that the foam material is in the wrong direction based on the second electrical state of the micro switch 17, the control unit 2 controls the vacuum solenoid valve 20 to cut off the vacuum supply to the vacuum suction cup 19, causing the vacuum suction cup 19 to release the foam material. At the same time, the control unit 2 controls the feeding mechanism to stop feeding and controls the audible and visual alarm to issue an alarm signal. The vacuum solenoid valve 20 is connected in series in the air circuit of the vacuum suction cup 19. Under normal circumstances, it is in the open state, and the vacuum suction cup 19 maintains negative pressure to adsorb the foam. When the control unit 2 detects that the micro switch 17 is in the open state, that is, the foam is in the wrong direction, it immediately sends a power-off signal to the vacuum solenoid valve 20. The solenoid valve closes, cuts off the vacuum supply, the vacuum suction cup 19 loses negative pressure, and the wrong foam falls off naturally. At the same time, the control unit 2 will also pause the feeding mechanism to prevent new foam from being pushed out and activate the audible and visual alarm to remind the operator to handle the situation.
