Waste film collecting device

Abstract

This utility model relates to a waste film collection device, which includes a material strip, an unwinding station for unwinding the material strip, a winding station for winding the material strip, and a film-adhesive station. The material strip includes a base layer and an adhesive layer, and the material strip is unwound and transported from the unwinding station and wound up at the winding station. The film-adhesive station is located on the material strip's transport path and includes a pressure bar positioned opposite the adhesive layer and a driver that drives the pressure bar to move towards or away from the adhesive layer. As a robotic arm transfers waste film onto the adhesive layer at the film-adhesive station, the pressure bar presses the waste film firmly and adheres it to the surface of the adhesive layer. This utility model, on the one hand, abandons the traditional unloading method by using a material strip with an adhesive layer. As the robotic arm places the waste film onto the adhesive layer, the pressure bar presses the waste film firmly and adheres it to the adhesive layer, greatly improving the success rate of waste film transfer. On the other hand, adhering the waste film to the material strip and performing winding effectively prevents waste film from flying away, facilitating centralized collection and processing.

Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment, and specifically relates to a waste film collection device. Background Technology

[0002] In the surface mount technology (SMT) production process, when mounting connectors, because the surface of the connector is uneven and lacks adsorption points, it is usually necessary to attach a film to the surface of the connector to form a flat adsorption surface, so as to facilitate the robot to pick up and place and assist in the mounting of the connector. After the mounting is completed, the film is removed and the removed film is transferred by the robot to the waste tank for collection.

[0003] However, in the actual film removal process, when the robotic arm transfers the removed waste film to the waste tank for unloading, the waste film is easily adsorbed onto the gripper of the robotic arm due to static electricity, making it difficult to remove. This results in the waste film not being collected smoothly and affects the robotic arm's ability to remove subsequent waste films. In addition, due to the small size of the waste film, even a slight airflow during the collection process can easily cause the waste film to fly around, making collection difficult. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a brand-new waste membrane collection device.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A waste film collection device includes a material strip, an unwinding station for unwinding the material strip, a winding station for winding the material strip, and a film-adhesive station. The material strip includes a base layer and an adhesive layer, and the material strip is unwound and transported from the unwinding station and wound up at the winding station. The film-adhesive station is located on the transport path of the material strip and includes a pressure bar disposed opposite to the adhesive layer and a driver for driving the pressure bar to move toward or away from the adhesive layer. As a robot transfers the waste film to the adhesive layer located at the film-adhesive station, the pressure bar presses the waste film and adheres it to the surface of the adhesive layer.

[0007] According to a specific embodiment and preferred aspect of this utility model, the pressure bar includes a bar body and an anti-sticking layer disposed on the side of the bar body near the adhesive layer. As the pressure bar moves towards the adhesive layer, the waste film is pressed between the anti-sticking layer and the adhesive layer. Here, the material strip is prevented from sticking to the pressure bar during film pressing.

[0008] Preferably, the anti-stick layer extends along the width of the strip.

[0009] Specifically, in the orthographic projection on the adhesive layer, the two ends of the anti-adhesive layer protrude outwards from opposite sides of the material strip. This increases the success rate of precise film pressing by the pressure bar.

[0010] According to another specific embodiment and preferred aspect of this utility model, the conveyor belt passes horizontally through the adhesive layer station while maintaining the adhesive layer facing upwards, and the pressure bar is vertically movable above the conveyor belt. This facilitates the waste film falling onto the adhesive layer.

[0011] Preferably, the material strip segment located at the film-adhesive station forms a placement area from one end. The robot transfers waste film into the placement area, and the driver drives the pressure bar to form a clearance position and a pressing position. In the clearance position, the pressure bar is located above the side of the placement area away from the robot. In the pressing position, the pressure bar presses the waste film onto the adhesive layer located in the placement area. Here, a fixed placement area is formed, and based on the switching of the pressure bar between the clearance position and the pressing position, it is convenient for the robot to accurately place the waste film each time and prevent interference.

[0012] Preferably, the driver drives the pressure rod to tilt up and down between the avoidance position and the pressing position. Here, based on a single power-driven tilting motion of the pressure rod, synchronous displacement of the pressure rod in the lateral and vertical directions is achieved, resulting in high pressure rod displacement efficiency, simple structure, and convenient implementation.

[0013] Preferably, the film-adhesion station further includes a horizontally arranged support base, on the top surface of which the material strip segment located at the film-adhesion station is supported. This provides effective support for the material strip segment passing through the film-adhesion station, preventing deformation of the material strip during film pressing and thus affecting its transport.

[0014] According to another specific embodiment and preferred aspect of this utility model, the unwinding station is located below the support base, and the winding station is located on one side of the support base. The material strip is unwound from the unwinding station and then transported upwards around the support base away from the winding station before proceeding towards the winding station. This design results in a compact structure that saves space.

[0015] Furthermore, an acute angle is formed between the side of the support base furthest from the winding station and the top surface of the support base. The material strip is conveyed by adhering to the side and top surfaces, while the side of the support base closest to the winding station has rounded corners. Here, the acute angle layout on one side of the support base ensures that the passing material strip remains flat to facilitate the adhesion of waste film. At the same time, the rounded corner layout on the other side reduces friction between the material strip and the support, thereby preventing the waste film adhered to the material strip from falling off.

[0016] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] In existing technologies, when a robotic arm transfers the detached waste film to a waste trough for unloading, the waste film is easily adhered to the grippers of the robotic arm due to static electricity, making it difficult to detach and hindering the collection of waste film. This also affects the robotic arm's ability to detach subsequent waste film. Furthermore, due to the small size of the waste film, even a slight airflow during collection can easily cause it to fly around, making collection difficult. This application addresses these shortcomings by comprehensively designing the waste film collection device, cleverly resolving the deficiencies of existing technologies. With this collection device, the unwinding station and the winding station work together to unwind the material strip from the unwinding station, pass through the film-adhesive station, and then wind it up to the winding station. The robotic arm transfers the waste film onto the adhesive layer at the film-adhesive station. Then, a driver moves a pressure bar towards the adhesive layer to press and adhere the waste film to the adhesive layer, transferring it from the robotic arm to the material strip. Finally, the material strip with the waste film attached is wound up to the winding station to complete the waste film collection. Therefore, compared with the prior art, this utility model abandons the traditional unloading method and adopts a material belt with an adhesive layer. As the robot arm places the waste film on the adhesive layer, the pressure bar presses the waste film tightly onto the adhesive layer, which greatly improves the success rate of waste film transfer. On the other hand, the waste film is pasted onto the material belt and rolled up, which effectively avoids the waste film flying and facilitates centralized collection and treatment.

[0031] like Figures 1 to 4 As shown, the waste film collection device of this embodiment includes a material strip 1, an unwinding station 2 for unwinding the material strip 1, a winding station 3 for winding the material strip 1, and a film adhesion station 4.

[0032] Specifically, the material tape 1 includes a base layer 10 and an adhesive layer 11. In this embodiment, the material tape 1 is a conventional sealing tape.

[0033] In this example, the unwinding station 2 includes an unwinding roller 20, a first guide roller 21, and an unwinding power unit (not shown in the figure, but easy to imagine). The strip is mounted on the unwinding roller 20 and rotated for unwinding and transmission. The winding station 3 includes a winding rack 30, a winding power unit 31, and a second guide roller 32. As the winding power unit 31 drives, the strip is wound onto the winding rack 30.

[0034] In this example, the film-adhesive station 4 is located on the conveying path of the material belt 1 and includes a pressure bar 40 disposed opposite to the adhesive layer 11 and a driver 41 that drives the pressure bar 40 to move toward or away from the adhesive layer. As the robot transfers the waste film to the adhesive layer 11 located at the film-adhesive station 4, the pressure bar 40 presses the waste film and adheres it to the surface of the adhesive layer 11.

[0035] In some specific embodiments, the conveyor belt 1 passes horizontally through the adhesive film station 4 while keeping the adhesive layer 11 facing upwards, and the pressure rod 40 is vertically movable above the conveyor belt 1. This facilitates the waste film falling onto the adhesive layer.

[0036] Simultaneously, the material strip segment located at the adhesive film station 4 forms a placement area q from one end. The robot transfers waste film into the placement area q. The driver 41 drives the pressure rod 40 to form a clearance position and a pressing position. In the clearance position, the pressure rod 40 is located above the side of the placement area q away from the robot. In the pressing position, the pressure rod 40 presses the waste film onto the adhesive layer 11 located in the placement area q. Here, a fixed placement area is formed, and based on the switching of the pressure rod between the clearance position and the pressing position, it is convenient for the robot to accurately place the waste film each time and prevent interference.

[0037] For ease of implementation, the pressure bar 40 includes a bar body 400 and an anti-adhesion layer 401 disposed on the side of the bar body 400 near the adhesive layer 11. The anti-adhesion layer 401 can be any conventional anti-adhesion material. As the pressure bar 40 moves toward the adhesive layer 11, the waste film is pressed between the anti-adhesion layer 401 and the adhesive layer 11. This prevents the material strip from sticking to the pressure bar during film pressing.

[0038] In some specific embodiments, the anti-stick layer 401 extends along the width of the strip 1, and in the orthographic projection on the adhesive layer 11, both ends of the anti-stick layer 401 protrude outward from opposite sides of the strip 1. This increases the success rate of precise film pressing by the pressure bar.

[0039] The actuator 41 employs a rodless cylinder to drive the pressure rod to tilt up and down between the avoidance position and the pressing position. Here, based on a single power-driven tilting motion of the pressure rod, synchronous displacement of the pressure rod in the lateral and vertical directions is achieved. The pressure rod displacement efficiency is high, and the structure is simple and easy to implement.

[0040] To further facilitate implementation, the film-adhesion station 4 also includes a horizontally arranged support base 42, on the top surface of which the material strip segment located at the film-adhesion station is supported. This provides effective support for the material strip segment passing through the film-adhesion station, preventing deformation of the material strip during film pressing and thus affecting its transmission.

[0041] In some specific embodiments, the unwinding station 2 is located below the support base 42, and the winding station 3 is located on the side of the support base 42 away from the material placement area q. The material strip 1 is unwound from the unwinding station 2 and passes around the side of the support base 42 near the material placement area q from bottom to top before being conveyed towards the winding station 3. This design is compact and saves equipment space.

[0042] Furthermore, an acute angle is formed between the side of the support 42 closest to the material placement area q and the top surface of the support 42. The material belt 1 is conveyed by adhering to the side and top surface of the support 42, while the side of the support 42 away from the material placement area q has a rounded corner. Here, the acute angle layout on one side of the support ensures that the material belt remains flat to facilitate the adhesion of waste film. At the same time, the rounded corner layout on the other side reduces friction between the material belt and the support, thereby preventing the waste film adhered to the material belt from falling off.

[0043] In summary, by adopting this collection device, the cooperation between the unwinding station and the winding station enables the material strip to be unwound and transported from the unwinding station, then passed through the film-adhesive station and wound up to the winding station. The robot then transfers the waste film to the adhesive layer located at the film-adhesive station. The driver then drives the pressure bar to move closer to the adhesive layer to press and adhere the waste film to the adhesive layer, thus transferring the waste film from the robot to the material strip. Finally, the material strip with the waste film attached is wound up to the winding station to complete the waste film collection. Therefore, compared with the prior art, this utility model, on the one hand, abandons the traditional unloading method and adopts a material strip with an adhesive layer. As the robotic arm places the waste film on the adhesive layer, the pressure bar presses the waste film firmly onto the adhesive layer, greatly improving the success rate of waste film transfer; on the other hand, the waste film is pasted onto the material strip and then wound up, effectively preventing the waste film from flying away and facilitating centralized collection and processing; thirdly, by using an anti-stick layer, the material strip is prevented from sticking to the pressure bar during film pressing; fourthly, a fixed-position material placement area is formed, and based on... The switching between the avoidance position and the clamping position of the pressure bar facilitates accurate placement of waste film by the robot arm each time, preventing interference; fifthly, based on the tilting motion of the pressure bar driven by a single power source, the pressure bar can be moved synchronously in the lateral and vertical directions, resulting in high pressure bar displacement efficiency, simple structure, and convenient implementation; sixthly, the acute angle layout on one side of the support base ensures that the passing material strip remains flat to facilitate the adhesion of waste film, while the rounded corner layout on the other side reduces friction with the material strip, thereby preventing the waste film adhered to the material strip from falling off.

[0044] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
