Description

Technical Field

[0001] This utility model relates to the field of film tearing, specifically a PIN pin top film mechanism. Background Technology

[0002] In the PCB manufacturing process, after the dry film of the inner or outer layer circuitry is exposed, the release film on the board surface needs to be peeled off before subsequent etching. Existing film-peeling equipment uses a slanted groove on the base. The PIN assembly slides along the groove, and a cylinder drives a slider within the groove, thus moving the PIN assembly. While this method ensures the stability of the PIN assembly movement, in practical applications, it has been found that because a single top-film mechanism in a factory needs to peel film from tens of thousands of boards per day, the slider needs to reciprocate tens of thousands of times within the groove daily. This excessive frequency causes wear and tear at the end of the groove due to impacts from the slider, leading to jamming at the end of the groove. This results in several defects: firstly, it prevents smooth top-film application; secondly, it necessitates replacing the top-film mechanism, increasing costs.

[0003] Therefore, it is necessary to provide a PIN pin top film mechanism. Utility Model Content

[0004] The present invention provides a PIN pin top film mechanism, which effectively solves the problems of short lifespan of the top film mechanism, easy damage leading to the inability of the top film to operate normally, and increased cost.

[0005] The technical solution adopted in this utility model is:

[0006] A PIN pin top film mechanism includes a base plate, a fixed seat mounted on the base plate, a slide plate slidably mounted on the fixed seat, a template mounted on the slide plate, and a first drive assembly mounted on the base plate for driving the slide plate to slide. It also includes a first guide rail vertically mounted on the slide plate, a lifting frame slidably mounted on the first guide rail, a motor screw module mounted on the slide plate for driving the lifting frame to move up and down, a second guide rail mounted along the X-axis on the lifting frame, a PIN component slidably mounted on the second guide rail, and a second drive assembly mounted on the slide plate for driving the PIN component to slide. The PIN component and the second drive assembly are floatingly connected.

[0007] Furthermore, the second drive assembly includes a mounting base on the slide plate, a second cylinder on the mounting base along the X-axis, and a push block at the output end of the second cylinder. The push block has a vertical slot. The PIN assembly includes a smooth plate slidably mounted on the second guide rail, several mounting blocks on the smooth plate, several PIN pins respectively mounted on the mounting blocks, and a locking block on the smooth plate. The locking block extends into the slot, causing the second cylinder to drive the push block to move and achieve a floating connection between the PIN assembly and the second drive assembly. The template has a clearance hole for the mounting block to avoid misalignment.

[0008] Furthermore, the first drive component includes a first cylinder disposed on the base plate along the X-axis direction, a first inclined slider disposed at the output end of the first cylinder, the first inclined slider being provided with a first inclined surface, and the lower end of the slide plate being provided with a second inclined surface that slides with the first inclined surface.

[0009] Furthermore, the template is provided with several airflow channels, one end of which is an air inlet and the other end of which is an air outlet. The air outlet is used to blow air onto the film that has been pushed open by the PIN assembly.

[0010] Furthermore, the motor lead screw module includes a motor mounted on the slide plate, a lead screw coaxially fixed on the motor shaft, and a nut threadedly connected to the lead screw, wherein the nut is fixedly connected to the lifting frame.

[0011] Furthermore, the base plate is provided with several mounting holes.

[0012] Furthermore, the fixed base is provided with two vertical sliding grooves, and the two sides of the slide plate are slidably connected to the two vertical sliding grooves respectively.

[0013] The beneficial effects of the utility model are as follows: By directly driving the PIN component along the second guide rail through the second drive component, the PIN component can be guided, and the friction of the PIN component during the sliding process can be reduced by the second guide rail. This will prevent the PIN component from sliding and wearing due to repeated film application, thus ensuring the service life of the PIN component, reducing the cost of maintenance and replacement of the mechanism, and ensuring smooth film application even under high-frequency operation.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, the embodiment of this application provides a PIN pin top film mechanism, the structure of which includes a base plate 1, a fixed seat 2 disposed on the base plate 1, a slide plate 3 slidably disposed on the fixed seat 2, a template 4 disposed on the slide plate 3, a first drive assembly 5 disposed on the base plate 1 for driving the slide plate 3 to slide, and also includes a first guide rail 6 vertically disposed on the slide plate 3, a lifting frame 7 slidably disposed on the first guide rail 6, a motor screw module 8 disposed on the slide plate 3 for driving the lifting frame 7 to rise and fall, a second guide rail 9 disposed along the X-axis direction on the lifting frame 7, a PIN component 10 slidably disposed on the second guide rail 9, and a second drive assembly 11 disposed on the slide plate 3 for driving the PIN component 10 to slide, wherein the PIN component 10 and the second drive assembly 11 are floatingly connected.

[0021] In actual use, after the board moves to the predetermined position, the first drive component 5 drives the slide plate 3 to slide vertically so that the template 4 presses the end face of the board. Then, the motor screw module 8 drives the lifting frame 7 to rise and fall to the predetermined height, so that the lifting frame 7 drives the second guide rail 9 and the PIN component 10 to rise and fall synchronously to the predetermined height. At this time, the PIN component 10 is at the height where it can top the film. Then, the second drive component 11 drives the PIN component 10 to slide horizontally along the second guide rail 9 to achieve top film.

[0022] In the above design, the PIN component 10 is directly driven to slide along the second guide rail 9 by the second drive component 11. This not only guides the PIN component 10, but also reduces the friction of the PIN component 10 during the sliding process by the second guide rail 9. This prevents the PIN component 10 from sliding and wearing due to repeated film application, ensuring the service life of the PIN component 10, reducing the cost of maintenance and replacement, and ensuring smooth film application even under high-frequency operation.

[0023] Specifically: such as Figure 3 and Figure 4 As shown, the second drive assembly 11 includes a mounting base 111 mounted on the slide plate 3, a second cylinder 112 mounted on the mounting base 111 along the X-axis, and a push block 113 mounted on the output end of the second cylinder 112. The push block 113 has a vertical slot. The PIN assembly 10 includes a smooth plate 1013 slidably mounted on the second guide rail 9, several mounting blocks 102 mounted on the smooth plate 1013, several PIN pins 103 respectively mounted on the mounting blocks 102, and a locking block 104 mounted on the smooth plate 1013. The locking block 104 extends into the slot, causing the second cylinder 112 to drive the push block 113 to move the locking block 104, thus achieving a floating connection between the PIN assembly 10 and the second drive assembly 11. The template 4 has a clearance hole for the mounting block 102 to avoid misalignment. The push block 113 and the locking block 104 are slidably connected vertically.

[0024] In actual use, when the second drive component 11 needs to drive the PIN component 10, the second cylinder 112 drives the push block 113 to extend, so that the push block 113 pushes the card block 104 through the inner wall of the card slot. This causes the card block 104 to drive the smooth plate 1013, the mounting block 102, and the PIN pin 103 to move synchronously, ultimately moving the PIN pin 103 to the predetermined position to achieve the top film. When the motor screw module 8 drives the lifting frame 7 to change height, the lifting frame 7 drives the PIN component 10 to rise and fall synchronously. During the rising and falling process of the PIN component 10, the card block 104 will rise and fall relative to the card slot but will not disengage from the card slot (the height of the card slot is greater than the stroke of the motor screw module 8), thus achieving a floating connection.

[0025] In the above design, the structural design and specific implementation of the second drive component 11 and the PIN component 10 can ensure that the PIN component 10 can be raised and lowered to different top film heights according to different board thicknesses, while ensuring that the second drive component 11 always cooperates with the PIN component 10 to ensure that the PIN component 10 can be pushed by the second drive component 11.

[0026] Specifically: such as Figure 2 and Figure 3As shown, the first drive assembly 5 includes a first cylinder 51 disposed on the base plate 1 along the X-axis direction, a first inclined slider 52 disposed at the output end of the first cylinder 51, the first inclined slider 52 is provided with a first inclined surface 520, and the lower end of the slide plate 3 is provided with a second inclined surface that slides with the first inclined surface 520.

[0027] In actual use, cylinder 51 drives slider 52 to slide, and the friction between the inclined plane and the second inclined plane compresses the slide plate 3, thereby making the slide plate 3 slide upward relative to the fixed seat 2. When the output end of cylinder 51 retracts, it drives slider 52 to move synchronously, so that the slide plate 3 returns to its original position under the action of gravity.

[0028] In the above design, the structural design and specific implementation of the first drive component 5 and the first slide plate 3 facilitate the lifting and lowering drive of the slide plate 3, thereby enabling the slide plate 3 to drive the template 4 to move stably.

[0029] Specifically: such as Figure 1 As shown, the template 4 is provided with several airflow channels. One end of the airflow channel is an air inlet, and the other end of the airflow channel is an air outlet 400. The air outlet 400 is used to blow air onto the film that is pushed open by the PIN component 10.

[0030] In actual use, when the PIN assembly 10 completes the top film so that the edge of the film is raised relative to the edge of the board, air is supplied to the airflow channel through an external air source, so that the airflow is blown into the gap between the board and the film from the air outlet 400, further separating the film and the board.

[0031] In the above design, the airflow channel design enables air to be blown onto the membrane that has been pushed open by the PIN component 10, thereby achieving further separation of the membrane from the substrate.

[0032] Specifically: such as Figure 1 and Figure 4 As shown, the motor lead screw module 8 includes a motor 81 mounted on the slide plate 3, a lead screw 82 coaxially fixed on the rotating shaft of the motor 81, and a nut 83 threadedly connected to the lead screw 82. The nut 83 is fixedly connected to the lifting frame 7.

[0033] In actual use, the motor 81 drives the lead screw 82 to rotate, and the rotation of the lead screw 82 causes the nut 83 to move along the axial direction of the lead screw 82, which in turn drives the lifting frame 7 to move along the axial direction of the lead screw 82.

[0034] In the above design, the lifting frame 7 is driven to rise and fall by the motor screw module 8. The precision transmission characteristics of the motor 81 can be used to achieve the precision of the adjustment of the lifting frame 7, which makes it easy for the lifting frame 7 to drive the PIN component 10 to make fine adjustments to achieve the predetermined top film height.

[0035] Specifically: such as Figure 1As shown, the base plate 1 is provided with a plurality of mounting holes 100.

[0036] In actual use, the PIN pin top film mechanism of this application is assembled on the external frame by passing bolts through the mounting hole 100.

[0037] In the above design, the structural design and specific implementation of the mounting hole 100 can effectively realize the assembly with the external frame.

[0038] Specifically: the fixed base 2 is provided with two vertical sliding grooves, and the two sides of the sliding plate 3 are slidably connected to the two vertical sliding grooves respectively.

[0039] In actual use, when the first drive component 5 drives the slide plate 3 to rise and fall, the two sides of the slide plate 3 slide within the vertical groove.

[0040] In the above design, the structural design and specific implementation of the two vertical grooves can effectively guide the slide plate 3.

[0041] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
