Description

Technical Field

[0001] This utility model relates to the field of robotic arm equipment technology, and in particular to an automatic adhesive plug removal device for the threaded hole of a mobile phone back panel. Background Technology

[0002] During the manufacturing process of mobile phone back panels, rubber plugs are needed to seal the bolt holes during the anodizing process to prevent blockage. These protective rubber plugs must be removed one by one during final product assembly.

[0003] Currently, the removal of rubber stoppers mostly relies on manual labor or repetitive gripping using simple single-head robotic arms. For workpieces with complex structures and multiple sealing interfaces in different directions, manual removal is inefficient, labor-intensive, and inconsistent. While existing automated single-head robotic arms can replace some manual labor, they require multiple positioning or gripper changes when dealing with multi-directional rubber stoppers, resulting in long cycle times and limited overall efficiency improvement.

[0004] Furthermore, whether done manually or with existing equipment, the collection of rubber stoppers after removal is often not effectively planned. They usually fall directly onto the equipment platform or the ground, requiring subsequent cleaning. This not only may disrupt the cleanliness and safety of the production line, but also adds extra handling procedures.

[0005] Therefore, there is an urgent need in this field for an automated device that can simultaneously and automatically remove rubber plugs from different positions on a workpiece and collect the removed rubber plugs in an orderly manner, so as to completely solve the problems of low efficiency and chaotic on-site management in the existing technology. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic adhesive plug removal device for the threaded holes of a mobile phone back panel, which is an integrated device that can efficiently and synchronously remove multiple adhesive plugs in different positions on a workpiece.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an automatic adhesive plug removal device for the threaded hole of a mobile phone back panel, comprising: Servo electric cylinder; A guide rail, which is arranged in parallel with the servo electric cylinder; A gripper mounting base is fixedly connected to the drive end of the servo electric cylinder and slides with the guide rail. A gripper assembly is disposed on the gripper mounting base. The gripper assembly includes multiple gripper units. Each gripper unit includes a gripper finger cylinder and a pair of pneumatic grippers driven by the gripper finger cylinder. The gripping directions of each pneumatic gripper are different, and they are used to remove and install rubber plugs in different positions on the workpiece to be removed. An air blowing component is disposed on the side of the gripper assembly and is used to blow off the rubber plug held on the pneumatic gripper.

[0008] Furthermore, it also includes a rubber stopper collection mechanism, which is disposed below the gripper assembly for collecting rubber stoppers that are blown off.

[0009] Furthermore, the rubber stopper collection mechanism includes a collection ramp, guide plates disposed on both sides of the collection ramp, and a rubber stopper collection box located at the end of the collection ramp.

[0010] Furthermore, it also includes a material receiving channel, the upper opening of which is located directly below the gripping end of the pneumatic gripper, and the lower end is connected to the inlet of the rubber stopper collection mechanism.

[0011] Furthermore, at least one of the gripper units has a flat gripper, and at least another gripper unit has a V-shaped gripper.

[0012] Furthermore, the air blowing component is an air blowing nozzle, and its air blowing direction is aligned with the clamping end of the pneumatic gripper.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model discloses an automatic adhesive plug removal device for threaded holes on mobile phone back panels. By setting up multiple gripper units with different clamping directions and driving them to move in coordination by a servo electric cylinder, it realizes one-time positioning and synchronous installation and removal of multiple adhesive plugs in different positions on the workpiece, completely avoiding the time waste caused by multiple positioning or tool replacement, and improving production efficiency.

[0014] Furthermore, by adopting a hybrid configuration that includes both flat and V-shaped grippers, it can simultaneously adapt to different clamping requirements and effectively cope with complex spatial layouts and diverse rubber plug shapes on workpieces.

[0015] Furthermore, it integrates air-blowing de-stopping and rubber stopper collection functions. Utilizing directional air blowing, the rubber stopper can be reliably detached from the gripper instantly and without contact. Subsequently, the detached rubber stopper is precisely guided into the collection ramp through the material receiving channel and finally collected into the collection box, realizing the entire process from disassembly and detachment to collection.

[0016] The overall layout of the device is reasonable, saving equipment space, reducing the complexity of the overall structure, and making it easy to deploy and maintain on the production line. Attached Figure Description

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

[0019] See Figures 1 to 3 The automatic plug removal device for the threaded holes on the back panel of the mobile phone includes a servo cylinder 1, a guide rail 2, a gripper mounting base 3, a gripper assembly 4, an air blowing component 5, a plug collection mechanism 6, and a material receiving channel 7. It aims to remove and collect plugs from multiple different positions on the workpiece, thereby improving work efficiency and site cleanliness.

[0020] Specifically, the guide rail 2 and the servo cylinder 1 are arranged in parallel. The gripper mounting base 3 is in sliding engagement with the guide rail 2 and is connected to the drive end of the servo cylinder 1. In this way, the servo cylinder 1 can precisely drive the gripper mounting base 3 to perform stable reciprocating lifting and lowering motion along the guide rail 2.

[0021] The gripper assembly 4 is bolted to the gripper mounting base 3. In this example, the gripper assembly 4 comprises multiple gripper units. Each gripper unit consists of a gripper finger cylinder 40 and a pair of pneumatic grippers 41 directly driven by it. The gripper units are spatially differentiated, so that the gripping directions of each pneumatic gripper 41 are different, thereby enabling them to approach and grip the rubber plug on the workpiece from different directions. In particular, as shown... Figure 2 As shown, the gripper unit is located in Figure 1 On the far right, the gripper finger cylinder 40 is connected to the output end of the horizontal drive cylinder 42. The horizontal drive cylinder 42 enables the overall horizontal advancement and reset of the gripper unit, thereby completing the removal of the rubber plug in the horizontal direction.

[0022] To further optimize the clamping effect, at least one clamping unit is equipped with a flat clamping jaw for clamping rubber plugs with flat end faces; while at least another clamping unit is equipped with a V-shaped clamping jaw for stabilizing the clamping of irregularly shaped rubber plugs.

[0023] The air blowing component 5 specifically employs an air blowing nozzle 50, which is fixed to the side of the gripper mounting base 3 via a mounting bracket (not shown in the figure). The outlet direction of the air blowing nozzle 50 is precisely positioned to align with the gripping end of the pneumatic gripper 41. After the pneumatic gripper 41 has finished gripping the rubber stopper, it will return to its original position and move downwards, stopping at a preset dislodging position near the air blowing nozzle 50. The air blowing nozzle 50 is connected to an external air source via a pipeline and is used to blow off the rubber stopper adhering to the gripper after dislodging.

[0024] Furthermore, in this example, the clamping unit, consisting of a servo cylinder 1, guide rail 2, gripper mounting base 3, gripper assembly 4, and air blowing component 5, is configured in multiple sets within the overall adhesive plug removal assembly. The specific number of sets can be flexibly adjusted according to actual needs. In this example, three sets are provided, each used to clamp adhesive plugs in different areas of the workpiece (such as the mid-frame of a mobile phone). By having the three sets of clamping units work sequentially or collaboratively, all target adhesive plugs on the workpiece can be removed in stages, thereby achieving complete and efficient cleaning of the entire workpiece (such as the mid-frame of a mobile phone).

[0025] The rubber stopper collection mechanism 6 is located below the gripper assembly 4 and is used to collect the rubber stoppers that are blown off. The mechanism includes a collection ramp 60, guide plates 61 installed on both sides of the collection ramp 60, and a rubber stopper collection box 62 that can be pulled out and installed at the end of the collection ramp 60.

[0026] The material receiving channel 7 is located between the pneumatic gripper 41 and the collecting inclined plate 60. Its upper opening is precisely positioned directly below the gripping position of the pneumatic gripper 41 to receive the blown-off rubber plugs; its lower outlet is connected to the inlet of the collecting inclined plate 60 to form a complete rubber plug guide path.

[0027] The work process is as follows: 1. Advancement and gripping: The servo electric cylinder 1 drives the gripper assembly 4 to move towards the workpiece to be disassembled until each pneumatic gripper 41 reaches its corresponding rubber plug position (aligning with the rubber plug at the corresponding workstation). Subsequently, all gripper finger cylinders 40 operate simultaneously, driving the pneumatic grippers 41 to close, thereby clamping all target rubber plugs.

[0028] 2. Pulling out and resetting: After confirming that all rubber plugs have been firmly gripped, the servo electric cylinder 1 drives the gripper assembly 4 to carry the pulled-out rubber plugs and move away from the workpiece (i.e., return to the initial position of the gripper).

[0029] 3. De-corkation and Collection: After the gripper assembly carries the removed rubber stopper to the preset de-corkation position, the gripper finger cylinder 40 drives the pneumatic gripper 41 to open; subsequently, the air nozzle 50 opens, using directional compressed airflow to completely blow off the rubber stopper attached to the gripper. The blown-off rubber stopper falls into the material receiving channel 7 directly below under the influence of gravity and airflow, and then slides into the rubber stopper collection mechanism 6 after being guided by it, finally collecting in the rubber stopper collection box 62.

[0030] 4. Standby: After the rubber plug collection is completed, the entire component returns to a state where it can be triggered to start again, waiting for the next working cycle.

[0031] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
