[0002] The PET film on existing circuit boards needs to be perforated on both sides, but the existing laser cutting equipment can only perforate one side.

The processing efficiency is low. In addition, the feeding mechanism of the existing laser cutting machine for perforating PET film is generally more complex, and the products need to be fed one by one in sequence, which results in low feeding efficiency and poor continuity.

If "first" or "second" is mentioned, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0019] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0020] like Figures 1 to 13 As shown, this invention discloses a laser perforation device for PET film, including a feeding mechanism 1, a first laser cutting mechanism 3, a connecting and flipping mechanism 2, and a second laser cutting mechanism 4. The feeding mechanism 1 includes a feeding bracket, a feeding transfer and positioning component, and a feeding translation component. The connecting and flipping mechanism 2 includes a connecting bracket, a connecting transfer and positioning component, a connecting and flipping component, and a connecting translation component. The first laser cutting mechanism 3 includes a support platform 301, a processing platform 302 disposed on the upper end of the support platform 301, and a dual laser head 303 disposed above the processing platform 302. An X-axis translation module 304 and a Y-axis translation module 305 disposed on the lower end of the X-axis translation module 304 are provided between the processing platform 302 and the support platform 301 to drive the processing platform 302 to perform X-axis and Y-axis translation, so as to facilitate synchronous cutting by the dual laser head 303. The second laser cutting mechanism 4 has the same structure as the first laser cutting mechanism 3.

[0021] In this invention, the feeding bracket 101 includes a lower accommodating space and an upper accommodating space. The lower accommodating space of the feeding bracket 101 is provided with a feeding lifting assembly 102. The feeding transfer positioning assembly includes a feeding transfer platform 103 located at the lower end of the upper accommodating space and a feeding transfer translation mechanism 104 that drives the feeding transfer platform 103 to translate. The feeding translation assembly includes a first feeding suction cup 105, a second feeding suction cup 106 located in the upper accommodating space, and a feeding translation module 107 that drives the first feeding suction cup 105 and the second feeding suction cup 106 to translate. The upper ends of the first feeding suction cup 105 and the second feeding suction cup 106 are respectively provided with a first feeding suction cup lifting mechanism 108 and a second feeding suction cup lifting mechanism 109. Both the first feeding suction cup lifting mechanism 108 and the second feeding suction cup lifting mechanism 109 are driven by lifting cylinders for lifting.

[0022] During operation, the loading and lifting assembly 102 lifts the product to be processed upwards, and then the first loading suction cup 105 descends to pick up the first product. After picking it up, the first loading suction cup 105 rises, and then the loading transfer and translation mechanism 104 moves the loading transfer platform 103 to below the first loading suction cup 105. The first loading suction cup 105 places the product on the loading transfer platform 103 for positioning. Then the loading transfer platform 103 is translated to the other end, and the second loading suction cup 106 picks up the first product on the loading transfer platform 103. Then the first loading suction cup 105 picks up the second product and places it on the loading transfer platform 103 for positioning. Then the first loading suction cup 105 picks up the second product. At this time, both the first loading suction cup 105 and the second loading suction cup 106 have products adsorbed. They can then be moved to the processing platform 302 of the first laser cutting mechanism 3 by the loading transfer module 107 for laser drilling on the first side.

[0023] The feeding mechanism 1 of the present invention can feed two products at the same time, and its feeding continuity and feeding efficiency are higher.

[0024] In this invention, the loading and lifting assembly 102 includes a receiving arm 116 disposed in the lower accommodating space and a loading and lifting module 117 that drives the receiving arm 116 to rise and fall. The receiving arm 116 includes at least two parallel inserts for stably lifting the product.

[0025] In this invention, the feeding mechanism 1 further includes a feeding trolley. The lower end of the feeding support 101 has a feeding port adapted to the feeding trolley on one side of its accommodating space. The feeding trolley includes a body 118 and a trolley handle 119 on one side of the body 118. The upper end of the body 118 has a feeding support arm and a feeding tray 120 detachably connected to the feeding support arm. Multiple product positioning posts 121 are provided around the upper periphery of the feeding tray 120. The feeding tray 120 is used to support and limit the movement of multi-layer products. When the feeding trolley enters the lower accommodating space of the feeding support 101, the feeding lifting module 117 moves the insert plate upwards, thereby lifting the entire feeding tray 120 to facilitate the suction cup picking up the products. Feeding via the feeding trolley makes operation more convenient and labor-saving.

[0026] In this invention, the loading transfer and translation mechanism 104 includes two parallel loading transfer and translation beams 111, two loading transfer synchronous belts 112 respectively mounted on the two loading transfer and translation beams 111, and a loading transfer drive motor 113 that drives the two loading transfer synchronous belts 112 to rotate. The loading transfer platform 103 is slidably connected to the two loading transfer and translation beams 111 at both ends, and is also fixedly connected to the two loading transfer synchronous belts 112 at both ends. The loading transfer drive motor 113 drives the loading transfer synchronous belts 112 to rotate, thereby driving the loading transfer platform 103 to translate. Its structure is simple and easy to control.

[0027] In this invention, the loading transfer platform 103 is provided with a loading transfer positioning mechanism. The loading transfer positioning mechanism includes a translation plate 114 disposed at the upper end of the loading transfer platform 103 and two abutting mechanisms respectively disposed on adjacent sides of the loading transfer platform 103. The abutting mechanism includes an abutting slide fixed to the lower end surface of the loading transfer platform 103, a plurality of abutting posts 115 connected to one end of the abutting slide and extending upward toward the side of the loading transfer platform 103, and an abutting cylinder for driving the abutting slide to translate. The lower middle part of the loading transfer platform 103 is also provided with a translation cylinder that can drive the translation plate 114 to move toward the two abutting mechanisms. The translation plate 114 and the corresponding positions of the loading transfer platform 103 and the abutting posts 115 are respectively provided with clearance grooves. When the first feeding suction cup 105 places the product on the feeding transfer platform 103, the translation cylinder will drive the translation plate 114 to move to the two sides where the abutment column 115 is located. The abutment cylinder will also drive the abutment column 115 to move in the opposite direction, so that the abutment columns 115 on both sides abut against the two sides of the product, thereby achieving product positioning and ensuring that the product position adsorbed by the first feeding suction cup 105 and the second feeding disk remains consistent.

[0028] In this invention, the loading translation assembly further includes a loading translation beam 110 connected to the loading translation module 107. The first loading suction cup lifting mechanism 108 and the second loading suction cup lifting mechanism 109 are fixed side by side on one side of the loading translation beam 110. The first loading suction cup 105 and the second loading suction cup 106 move synchronously, which is simple in structure and easy to control.

[0029] In this invention, both the loading translation module 107 and the loading lifting module 117 are lead screw modules, which have higher control precision.

[0030] In this invention, the second feeding suction cup 106 is also equipped with a CCD component, which can identify the code on the product and provide a processing program for subsequent laser cutting of different product models.

The connecting flipping component 203 includes a flipping lifting module disposed on one side of the lower accommodating space, a rotary drive mechanism connected to the flipping lifting module and a flipping suction cup connected to the rotary drive mechanism.

[0033] During operation, the first connecting suction cup 214 and the second connecting suction cup 215 simultaneously pick up two products with one side processed from the processing platform 302 of the first laser cutting mechanism 3. Then, the second connecting suction cup 215 places the product on the connecting transfer platform 205 for positioning. At this time, the flip suction cup flips downward and moves upward through the flip lifting module. Then, the connecting transfer platform 205 moves to the lower end of the flip suction cup, and the flip suction cup picks up the product. The connecting transfer platform 205 moves to the other end, and at this time, the flip suction cup flips the product upward. After flipping, the fourth connecting suction cup 217 moves above the product and picks it up. Then, the first connecting suction cup 214 places the product on the connecting transfer platform 205 for positioning. The same flip suction cup picks up and flips the product again. Then, the third connecting suction cup 216 picks up the product. Finally, the third connecting suction cup 216 and the fourth connecting suction cup 217 simultaneously move the two flipped products to the processing platform 302 of the second laser cutting mechanism 4 for laser drilling on the other side.

[0034] The connecting and flipping mechanism 2 can pick up and flip a product that has been processed on one side and directly transport it to the next processing area, which greatly improves the efficiency of double-sided processing.

[0035] In this invention, the connecting transfer translation mechanism includes two parallel connecting transfer translation beams 206, two connecting transfer synchronous belts 207 respectively mounted on the two connecting transfer translation beams 206, and a connecting transfer drive motor 208 that drives the two connecting transfer synchronous belts 207 to rotate. The two ends of the connecting transfer platform 205 are slidably connected to the two connecting transfer translation beams 206, and the two ends of the connecting transfer platform 205 are also fixedly connected to the two connecting transfer synchronous belts 207. The connecting transfer drive motor 208 drives the two connecting transfer synchronous belts 207 to rotate, thereby driving the connecting transfer platform 205 to translate. Its structure is simple and easy to control.

[0036] In this invention, the connecting transfer platform 205 is provided with a connecting transfer positioning mechanism. The connecting transfer positioning mechanism has the same structure as the loading transfer positioning mechanism and is also used to realize the positioning of the product and ensure the consistency of the product position after flipping.

The third connecting suction cup 216 and the fourth connecting suction cup 217 are respectively connected to the third connecting suction cup lifting mechanism 220 and the fourth connecting suction cup lifting mechanism 221. The structure is simple and easy to control.

[0039] In this invention, both the docking translation module 211 and the docking lifting module 222 are lead screw modules, which have higher control precision.

[0040] In this invention, the laser perforation device for the PET film also includes a feeding mechanism 5, which has the same structure as the feeding mechanism 1, but the feeding sequence is the reverse of the feeding sequence.

[0041] In this invention, by setting up a connecting flipping component 203, a connecting transfer positioning component 202, and multiple connecting robots to cooperate, the product transfer flipping and conveying to the next process can be directly completed, realizing double-sided processing of PET, which greatly improves the processing continuity and processing efficiency. In addition, the feeding mechanism 1 is simpler. Feeding is made more convenient and labor-saving by feeding through a feeding trolley. Feeding is made through two feeding suction cups, which makes the feeding continuity and feeding efficiency higher.
