Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment, and specifically relates to an automatic film peeling 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 the connector and assist in the mounting of the connector. The film is removed after the mounting is completed.

[0003] However, in the actual film removal process, due to the influence of the film application error on the connector surface, and the fact that the edge of the film exposed on the connector for the robot to grip is easily deformed downward by external force, the edge position of the film cannot be accurately controlled, making positioning difficult. Existing robots cannot accurately position the edge of the film and successfully grip it, resulting in a low overall film removal rate. Manual re-inspection and secondary film removal are required, which is cumbersome and inefficient. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved automatic film peeling device.

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

[0006] An automatic film-removing device is used to remove a diaphragm from the top surface of a connector, wherein the diaphragm protrudes from the connector from one side edge, and the side of the connector corresponding to the direction in which the diaphragm protrudes forms a reference surface. The film-removing device includes a base, a clamping assembly, and a film-removing power unit. The clamping assembly includes an upper clamp and a lower clamp, which are spaced apart on the base to form a clamping area, and a clamping power member that drives the upper clamp and the lower clamp to close or open towards each other. The film-removing power unit is used to drive the base to move closer to or away from the connector so that the upper clamp and the lower clamp form a first position and a second position. Based on the cooperation of the clamping power member and the film-removing power unit, when in the first position, the lower clamp is in contact with the reference surface, and the diaphragm is inserted into the clamping area from the edge and clamped. When in the second position, the upper clamp and the lower clamp drive the diaphragm to be peeled off from the connector synchronously.

[0007] According to a specific embodiment and preferred aspect of this utility model, in the first position, the diaphragm is supported on the lower clamping surface formed by the lower chuck, and the clamping power member drives the upper chuck to move up and down to clamp or release the diaphragm. Here, as the lower chuck contacts the reference surface, the support of the formed lower clamping surface ensures that the edges of the diaphragm are flat and clamped, ensuring the force-bearing surface during clamping and preventing it from falling off during disassembly and transfer.

[0008] Preferably, the lower clamp also has a limiting surface that intersects with the lower clamping surface and forms an angle, wherein the opening of the angle faces the reference surface. In the first position, the diaphragm is confined between the limiting surface and the lower clamping surface from its edge. Here, an abutment limit is formed on the edge of the diaphragm to prevent it from tilting up and detaching from the clamping area.

[0009] Furthermore, the angle formed between the limiting surface and the lower clamping surface is an acute angle.

[0010] Preferably, in the first position, the lower clamping surface formed by the lower clamp is flush with the top surface of the connector, or the lower clamping surface is flush with the top surface of the connector from one side and inclined downward relative to the other side.

[0011] According to another specific embodiment and preferred aspect of this utility model, a slide rail is formed on the base, with its extension direction intersecting the reference plane. The lower clamp is slidably connected to the slide rail. The clamping assembly also includes a sensor fixed on the base. Based on the lower clamp contacting the reference plane, as the base approaches the connector, the lower clamp moves relative to the slide rail and triggers the sensor. Here, based on the sliding arrangement of the lower clamp, during the contact with the reference plane, the lower clamp slides relative to the slide rail and triggers the sensor, achieving accurate detection of the lower clamp's position and ensuring that the lower clamp is precisely in the first position each time the film is removed.

[0012] Preferably, the slide rail is perpendicular to the reference surface; and / or, when the lower clamp triggers the sensor, the upper and lower clamping surfaces formed by the upper and lower clamps are aligned vertically from the center. This ensures accurate clamping of the diaphragm; at the same time, to facilitate continuous diaphragm removal for different connectors, an elastic element can be provided between the lower clamp and the base to achieve automatic reset when it is removed from the reference surface.

[0013] Preferably, the base includes a fixed base, a rotating base rotatably connected to the fixed base about a vertical centerline, and a rotational power component. Multiple sensors are distributed circumferentially around the rotating base on the fixed base. An upper clamp is movably connected to the rotating base and connected to the clamping power component from its upper end. A slide rail is fixedly mounted on the rotating base and rotates with the rotating base to align the lower clamp with a reference surface. When the centers of the upper and lower clamping surfaces are aligned vertically, the lower clamp triggers the corresponding sensor. This design allows for flexible removal of the protective film from connectors with different installation orientations, offering strong practicality.

[0014] Specifically, the rotating power component includes a rotary motor fixed on a fixed base, a power gear mounted on the output shaft of the rotary motor, and a transmission gear mounted on the rotating base and meshing with the power gear. This ensures precise transmission and improves the control accuracy of the rotation angle of the rotating base.

[0015] Furthermore, the film-unwrapping power unit includes a first movable seat that reciprocates laterally along a first horizontal direction, a second movable seat disposed on the first movable seat and reciprocating laterally along a second horizontal direction, and a lifting cylinder disposed on the second movable seat and driving the base to move up and down, wherein the first and second horizontal directions are perpendicular to each other. This not only facilitates control of the lateral and vertical positions of the upper and lower clamps to precisely approach or move away from the connector; but also, based on the displacement in the first and second horizontal directions, it enables the relative positioning of connectors at various locations on the same circuit board, resulting in a simple structure and convenient implementation.

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

[0017] Existing technologies are affected by errors in the film application on the connector surface. Furthermore, the exposed edges of the film on the connector, where it is gripped by a robotic arm, are prone to downward deformation under external forces. Precise control of the film's edge position makes positioning difficult, resulting in low overall film removal rates. This necessitates manual re-inspection and secondary film removal, which is cumbersome and inefficient. This application addresses these shortcomings by redesigning the structure of the automatic film removal device. With this device, when the circuit board is in the film removal station, the film removal motor, through the cooperation of the clamping and film removal components, drives the base to move closer to the connector, moving the upper and lower clamps to a first position. In this first position, the lower clamp is in contact with the reference surface, and the film is inserted into the clamping area from the edge and clamped by the closing of the upper and lower clamps. Then, the film removal motor drives the base away from the connector, moving the upper and lower clamps to a second position, where the film is simultaneously peeled off the connector. Therefore, compared with the prior art, this utility model, based on the cooperation of the clamping power component and the film peeling power device, enables the upper and lower clamps to accurately clamp the film with one side of the connector as a reference and peel it off from the connector as the base moves, effectively improving the success rate of film peeling, reducing the frequency of manual intervention, and significantly improving the film removal efficiency.

[0032] like Figures 1 to 5 As shown, the automatic film-removing device of this embodiment is used to remove the film P on the top surface of the connector Q, and the film-removing device includes a base 1, a clamping assembly 2, and a film-removing power unit 3.

[0033] Specifically, in this embodiment, when the diaphragm P is attached to the top surface of the connector Q, one side edge of the diaphragm P protrudes outward from the connector Q, and the side of the connector Q corresponding to the protruding direction of the diaphragm P forms a reference surface m0.

[0034] In this example, the base 1 includes a fixed base 10, a rotating base 11 rotatably connected to the fixed base 10 about a vertical center line, and a rotational power component 12.

[0035] In some specific embodiments, the fixed base 10 is provided with multiple sensors 100, which are distributed circumferentially around the rotating base 11. In this embodiment, the sensors 100 are soft-touch sensors. A horizontally extending slide rail 110 is fixedly provided at the bottom of the rotating base 11. There are two slide rails 110 arranged side-by-side with intervals. The rotational power component 12 includes a rotary motor 120 fixed on the fixed base 10, a power gear 121 mounted on the output shaft of the rotary motor 120, and a transmission gear 122 fixed on the rotating base 11 and meshing with the power gear 121. With the cooperation of the rotary motor 120, the power gear 121, and the transmission gear 122, the rotating base 11 is driven to rotate around the vertical centerline so that the extension direction of the slide rail 110 intersects with the reference plane m0. Most preferably, the extension direction of the slide rail 110 is perpendicular to the reference plane m0. This ensures precise transmission and improves the control accuracy of the rotation angle of the rotating base.

[0036] In this example, the clamping assembly 2 includes an upper clamp 20 and a lower clamp 21 that are spaced apart on the base 1 to form a clamping area q, and a clamping power member 22 that drives the upper clamp 20 and the lower clamp 21 to close or open towards each other.

[0037] In some specific embodiments, the clamping power member 22 adopts a conventional telescopic power mechanism and is fixedly installed on the fixed base 10; the upper clamp 20 is a vertically extending column, which is movably connected to the rotating base 11 and connected to the telescopic end of the clamping power member 22 from the upper end. That is, a vertically extending channel is formed on the rotating base 11, the upper clamp 20 is inserted into the channel and protrudes from the bottom downward between the two slide rails 110; the lower clamp 21 is slidably connected to the two slide rails 110, and the lower clamp 21... The sensor 100 can be triggered while sliding along the slide rail 110. When the lower chuck 21 triggers the sensor 100, the upper and lower clamping surfaces formed by the upper and lower chucks 20 and 21 are aligned vertically from the center. As the rotating base 11 rotates by a certain angle, the slide rail 110 rotates with the rotating base 11 to drive the lower chuck 21 to align with the reference surface m0. When the upper and lower clamping surfaces formed by the upper and lower chucks 20 and 21 are aligned vertically from the center, the lower chuck 21 triggers the sensor 100 in the corresponding direction. This allows for flexible removal of the protective film from connectors with different installation orientations, making it highly practical.

[0038] Meanwhile, the upper chuck 20 forms an upper clamping surface m1 from its lower end face, and the lower chuck 21 extends downward from the slide rail 110 and bends to one side at the bottom to form a lower clamping surface m2 located below the upper chuck 20. The upper chuck 20 is driven up and down by the clamping power member 22 to clamp or release the diaphragm. A limiting surface m3 is also formed on the lower chuck 21, which intersects with the lower clamping surface m2 and forms an angle, wherein the angle opening faces the reference surface m0 and is an acute angle.

[0039] To facilitate continuous film removal for different connectors, a fixing module k0 is fixedly provided at one end of the slide rail 110. The lower clamp 21 is slidably connected to the two slide rails 110 via a slider k1 (the slider k1 can trigger the sensor 100). The slider k1 and the fixing module k0 are provided with elastic elements to drive the lower clamp 21 to maintain a tendency to move towards the other end of the slide rail 110, thereby realizing the automatic reset of the lower clamp 21.

[0040] In this example, the film-removing power unit 3 drives the base 1 to move closer to or further away from the connector Q, thereby causing the upper clamp 20 and the lower clamp 21 to form a first position and a second position. Based on the cooperation of the clamping power unit 22 and the film-removing power unit 3, in the first position, the lower clamp 21 is in contact with the reference surface m0, and the diaphragm P is inserted from the edge into the clamping area q and clamped. In the second position, the upper clamp 20 and the lower clamp 21 drive the diaphragm P to be simultaneously removed from the connector Q. It should be noted that this application does not limit the specific location of the second position, as long as it satisfies the requirement of removing the diaphragm P from the connector Q.

[0041] In other words, based on the lower chuck 21 abutting against the reference surface m0, as the base 1 approaches the connector Q, the lower chuck 21 moves relative to the slide rail 110 to the first position and triggers the sensor 100 to indicate that the lower chuck 21 has moved into place. When in the first position, the lower clamping surface m2 formed by the lower chuck 21 is flush with the top surface of the connector on one side and inclined downward relative to the other side. The diaphragm is supported on the lower clamping surface m2 and is limited from the edge between the limiting surface m3 and the lower clamping surface m2. The upper chuck 20 clamps the diaphragm downward.

[0042] Furthermore, the film-removing power unit 3 includes a first movable seat 31 driven by a conventional power screw mechanism to reciprocate laterally along a first horizontal direction, a second movable seat 32 driven by a power screw mechanism mounted on the first movable seat 31 to reciprocate laterally along a second horizontal direction, and a lifting cylinder 33 mounted on the second movable seat 32 and driving the base 1 to move up and down, wherein the first and second horizontal directions are perpendicular to each other. This not only facilitates the control of the lateral and vertical positions of the upper and lower clamps to precisely approach or move away from the connector; but also, based on the displacement in the first and second horizontal directions, it enables the relative positioning of connectors at various locations on the same circuit board, resulting in a simple structure and convenient implementation.

[0043] In summary, when the circuit board is in the film removal station, based on the cooperation of the clamping power unit and the film removal power unit, the film removal power unit drives the base to move closer to the connector, thereby driving the upper and lower clamps to move to the first position. At the first position, the lower clamp is in contact with the reference surface, and the film is inserted into the clamping area from the edge and clamped by the upper and lower clamps closing towards each other. Then, the film removal power unit drives the base to move away from the connector, thereby driving the upper and lower clamps to move to the second position, and the film is simultaneously peeled off from the connector. Therefore, compared with the prior art, this utility model, on the one hand, is based on the cooperation of the clamping power component and the film-removing power component, so that the upper and lower clamps can accurately clamp the film with one side of the connector as a reference and peel it off from the connector, effectively improving the success rate of film removal, reducing the frequency of manual intervention, and significantly improving the film removal efficiency. On the other hand, as the lower clamp is in contact with the reference surface, the support of the formed lower clamping surface ensures that the edge of the film is flat and clamped tightly, ensuring the force surface during clamping and preventing it from falling off during removal and transfer. On the third hand, based on the sliding setting of the lower clamp, during the process of contacting the reference surface, the lower clamp slides relative to the slide rail and triggers the sensing component to achieve accurate detection of the position of the lower clamp, ensuring that the lower clamp is accurately in the first position every time the film is removed. On the fourth hand, it can flexibly remove the film from connectors with different installation directions, which is highly practical. On the fifth hand, it not only facilitates the control of the horizontal and vertical positions of the upper and lower clamps to accurately approach or move away from the connector; at the same time, based on the displacement in the first and second horizontal directions, it can relative position the connectors at various positions on the same circuit board, with a simple structure and convenient implementation.

[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.
