Description

Technical Field

[0001] This utility model relates to the field of chip substrate adhesive removal technology, and in particular to a material gripping device for an adhesive removal machine. Background Technology

[0002] In the modern electronics manufacturing industry, chip substrates are key carrier components. When using a de-adhesive machine to remove the adhesive strips from the chip substrates, a gripping device is needed to grab the chip substrates conveyed by the feeding device and move them to the de-adhesive table of the de-adhesive machine, where the adhesive is removed by cylinder pressing.

[0003] Currently, most common material gripping devices use clamping structures made of metal or rigid plastic to directly grip the material. While this structure offers high clamping force and structural strength, the lack of an effective buffering mechanism makes it prone to stress concentration at the edges of the chip substrate due to rigid contact during gripping. This can lead to quality problems such as cracks, chipping, and even breakage, severely impacting product yield and reliability. Furthermore, traditional clamping structures are not quick enough when releasing material, affecting overall operational efficiency. Utility Model Content

[0006] Preferably, cylinders are installed on both sides of the gripping seat, the piston ends of the cylinders are connected to both sides of the movable seat, a double-headed cylinder is installed on the lower side of the movable seat, and gripping plates are connected to the piston ends of both ends of the double-headed cylinder.

[0007] Preferably, a conveyor belt is installed on the underside of the top plate, and one end of the conveyor belt is connected to the material gripper.

[0008] Preferably, the protective component includes a rubber strip that is snapped into an installation groove in the material gripper plate.

[0009] Preferably, a plurality of springs are installed in the mounting groove, and one side of the rubber strip is in contact with the springs.

[0010] Preferably, both sides of the gripping plate are provided with protrusions, and the protrusions are slidably connected to the openings on both sides of the rubber strip.

[0013] Preferably, a spring three is installed in a groove on one side of the strip plate, and one end of the spring three is connected to the push plate.

[0014] This utility model provides a material gripping device for a degumming machine, which, compared with the prior art, offers the following advantages:

[0015] 1. This utility model, by installing rubber strips on both sides of the gripping plate, ensures that the rubber strips contact the edges of the chip substrate, effectively preventing potential damage to the chip substrate during clamping. Specifically, when clamping force is applied to the rubber strips, the rubber strips compress the spring inward, thus providing a buffering effect and avoiding stress concentration and substrate breakage that may be caused by direct hard contact. Furthermore, the rubber strips are fixed in a specially designed mounting groove by a limiting plate, ensuring stability during operation and facilitating quick replacement, thereby improving maintenance efficiency and equipment flexibility.

[0016] 2. This utility model achieves a more efficient and gentler material gripping and releasing process by installing a support rod and a push plate between two sets of gripping plates. Specifically, during the gripping operation, the push plate contacts the upper side of the material and causes the spring three to contract inward, thereby ensuring that the material is gripped quickly and stably. When the gripping plate needs to release the material, the elastic restoring force of the spring three causes the push plate to rebound quickly, allowing the material to quickly detach from the gripping device and achieve efficient release.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1-8 This utility model provides a material gripping device for a de-adhesive machine, including a machine body 1, a de-adhesive table 2 at the upper end of the machine body 1, a support 3 at the feeding end of the machine body 1, a top plate 4 at the upper end of the support 3, and a material gripping mechanism installed on the top plate 4. The material gripping mechanism grips the chip substrate in the feeding mechanism and moves the chip substrate to the de-adhesive table 2 for de-adhesive removal.

[0030] The material gripping mechanism includes a top plate 4, on which a pair of drive wheels 6 are rotatably mounted. The two sets of drive wheels 6 are connected by a drive belt 7 and run synchronously. At least one of the drive wheels 6 is driven by a motor 5, preferably a servo motor with forward and reverse rotation function, to realize the reciprocating motion control of the drive belt 7. A connector 8 is fixedly installed on the drive belt 7, and the lower end of the connector 8 is fixedly connected to one side of the material gripping seat 10, thereby driving the material gripping seat 10 to reciprocate in the horizontal direction, realizing automatic feeding and positioning of the material gripping action.

[0031] Furthermore, a conveyor belt 9 is provided on the lower surface of the top plate 4. One end of the conveyor belt 9 is connected to the material gripper 10. When the material gripper 10 moves with the transmission belt 7, the conveyor belt 9 can move synchronously, playing an auxiliary support and guiding role, improving the stability of the material gripper 10 during movement, and preventing displacement deviation caused by vibration or eccentric load.

[0032] Cylinders 11 are provided on both sides of the gripping seat 10. The piston rod ends of the cylinders 11 are connected to both sides of the moving seat 12 to drive the moving seat 12 to move up and down. When the gripping seat 10 moves to directly above the material to be gripped, the cylinders 11 are activated, pushing the moving seat 12 downward to approach the material surface.

[0033] A double-headed cylinder 13 is provided at the bottom of the movable seat 12. The two piston rods of the double-headed cylinder 13 are respectively connected to two gripping plates 14. When the movable seat 12 descends to the position, the double-headed cylinder 13 drives the two gripping plates 14 to extend to both sides, so that they are located at the outer edges of the material on both sides; then the double-headed cylinder 13 retracts in the opposite direction, driving the two gripping plates 14 to move towards the middle, clamping the two sides of the material, and completing the gripping action.

[0034] The clamping part of the material gripping mechanism is equipped with a protective component to improve the safety and reliability of the clamping process and prevent damage to the material during the clamping process. Specifically, the protective component includes a rubber strip 147, which is snapped into the mounting groove 141 opened in the material gripping plate 14 and forms a detachable connection structure with the mounting groove 141, which is convenient for subsequent replacement and maintenance.

[0035] Furthermore, multiple springs 142 are provided inside the mounting groove 141, and one side of the rubber strip 147 contacts and is supported by the springs 142. When the gripping plate 14 clamps the material, the rubber strip 147 first contacts the material surface and is squeezed, thereby compressing the springs 142 inward. By utilizing the elastic deformation of the rubber strip 147 itself and the buffering effect of the springs 142, flexible clamping of the chip substrate edge is achieved, effectively avoiding stress concentration or physical damage caused by rigid contact.

[0036] To further improve the stability of the rubber strip 147 in the mounting groove 141, protrusions 143 are provided on both sides of the gripping plate 14. The protrusions 143 slide with the openings at both ends of the rubber strip 147 to limit and guide, preventing the rubber strip 147 from shifting or falling off during use.

[0037] In addition, symmetrical grooves 144 are provided on one side of the gripping plate 14, and a limiting plate 145 is slidably disposed within the grooves 144. The lower end of the limiting plate 145 is connected to the bottom of the groove 144 via a second spring 146. When the rubber strip 147 is inserted into the mounting groove 141, the limiting plate 145 can restrict the rubber strip 147 under the elastic force of the second spring 146, thereby further enhancing the stability and fit of the rubber strip 147 during the gripping process and ensuring that it is always in an effective clamping position.

[0038] To further optimize the material handling effect, support rods 15 are symmetrically arranged on the movable seat 12. A strip plate is fixedly connected to the top of the support rod 15, and a push plate 152 is provided on the upper side of the strip plate. A groove is opened on one side of the strip plate, and a spring 151 is installed in the groove. One end of the push plate 152 is connected to the spring 151 and can float up and down relative to the strip plate under the action of the spring 151.

[0039] During the actual material handling process, when the material handling plate 14 descends above the chip substrate, the push plate 152 first contacts the upper surface of the chip substrate and is subjected to pressure as the material handling action continues, thereby compressing the spring 151 and causing deformation. At this time, the push plate 152 applies a certain pre-pressure to the material, which helps the material handling plate 14 to quickly and accurately clamp both sides of the material, improving material handling efficiency and stability.

[0040] When the material is picked up and needs to be released, the double-headed cylinder 13 drives the picking plate 14 to open outward, and the push plate 152 quickly rebounds upward under the reset force of the spring 151, pushing the material away from the picking area and allowing it to fall smoothly into the degumming table 2, thereby achieving efficient and stable material transfer operation.

[0041] In summary, the working principle of the material gripping device for a degumming machine according to this utility model embodiment is as follows: the motor 5 drives the transmission belt 7 to move the material gripping seat 10, the cylinder 11 controls the moving seat 12 up and down, the double-headed cylinder 13 drives the material gripping plate 14 to clamp the two sides of the material, the rubber strip 147 and the spring 142 buffer and protect the chip substrate, and the push plate 152 assists in gripping the material and quickly releases the material to the degumming table 2, so as to realize automatic, efficient and safe material gripping.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
