Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board processing equipment technology, and in particular to an automatic material handling device and pressing system for a pressing device. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards. They are favored for their excellent characteristics such as light weight, thinness, easy installation, and ability to be freely bent and folded. By embedding circuit designs on flexible, thin plastic sheets, a large number of precision components can be stacked in narrow and limited spaces, thus forming flexible circuits.

[0003] Currently, flexible circuit boards are bonded together with a protective film on both the top and bottom for three purposes: first, to enhance the adhesion between the protective film and the flexible circuit board; second, to prevent abnormalities in the reliability testing of the bonding material; and third, to improve the stability of the electrical testing performance of the flexible circuit board. The bonding process is performed using a bonding device that uses high-temperature sealing to adhere the bonding material—the protective film—to the surface of the flexible circuit board. The internal heating plate of the bonding device is made of silicone and fiberglass cloth, providing excellent sealing and reducing air bubbles and excess adhesive during the process, thus achieving its intended purpose.

[0004] However, the existing pressing process still relies on manual handling of material handling. Manual handling of flexible circuit boards not only increases production costs and reduces efficiency, but also, during the pressing process, the temperature of the pressing device reaches as high as 175°C. This high temperature causes the pressing protective film and the flexible circuit board to adhere tightly to the hot plate surface of the pressing device. Because the pressed flexible circuit board needs to be manually separated and removed, improper manual handling can cause the edges of the flexible circuit board to warp, affecting production yield. Utility Model Content

[0063] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0064] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to fully and completely disclose the present invention and to fully convey its scope to those skilled in the art. The terminology used in the exemplary embodiments illustrated in the drawings is not intended to limit the present invention. In the drawings, the same units / elements are referred to by the same reference numerals.

[0065] Unless otherwise stated, the terms used herein (including technical terms) have their common meaning as understood by one of ordinary skill in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have a meaning consistent with the context of their relevant field, and not to be interpreted as having an idealized or overly formal meaning.

[0066] like Figure 1 As shown, an embodiment of this utility model provides an automatic material handling device for a pressing device 100. The pressing device 100 includes a first hot pressing assembly 101 and a second hot pressing assembly 102 rotatably connected to one side of the first hot pressing assembly 101. The first hot pressing assembly 101 includes a lower cover and a lower hot pressing plate located on the upper surface of the lower cover, the lower hot pressing plate being used to support the flexible circuit board to be pressed; the second hot pressing assembly 102 includes an upper cover and an upper hot pressing plate opposite to the first hot pressing assembly 101. One side of the second hot pressing assembly 102 is rotatably connected to the first hot pressing assembly 101 to open or close the second hot pressing assembly 102 relative to the first hot pressing assembly 101.

[0067] Protective films are provided on the upper and lower surfaces of the flexible circuit board to be pressed. When the second hot pressing assembly 102 is closed with the first hot pressing assembly 101, the flexible circuit board placed inside can be pressed by the upper and lower hot pressing plates, that is, protective films are attached to both surfaces of the flexible circuit board.

[0068] In this embodiment, the automatic material handling device includes:

[0069] First guide rail 1, first guide rail 1 is along the horizontal direction (e.g. Figure 1 (As shown in the x-direction) is positioned above the pressing device 100;

[0070] The first clamping assembly 2 and the second clamping assembly 3 are disposed on the opposite open side of the first hot pressing assembly 101 and the second hot pressing assembly 102 of the pressing device 100 and are movably connected to the first guide rail 1. The first clamping assembly 2 is used to clamp the flexible circuit board that has been pressed, and the second clamping assembly 3 is used to clamp the flexible circuit board to be pressed.

[0071] A first driving mechanism and a second driving mechanism are connected. The first driving mechanism is connected to the first clamping assembly 2, and the second driving mechanism is connected to the second clamping assembly 3. The first driving mechanism and the second driving mechanism respectively drive the first clamping assembly 2 and the second clamping assembly 3 to reciprocate along the first guide rail 1.

[0072] Specifically, the flexible circuit board to be pressed is placed into the pressing device 100 by the second clamping component 3. After the pressing device 100 completes the pressing operation, the first clamping component 2 clamps the pressed flexible circuit board and removes it from the pressing device 100. Therefore, the insertion and removal of the flexible circuit board does not need to be manually completed by the operator, which avoids the warping and deformation of the edge of the flexible circuit board, improves the production yield, and makes the operation more convenient and efficient due to the ability to automatically feed and remove materials, thereby improving production efficiency and reducing production costs.

[0073] In this embodiment, the guide rail mounting plate 11 extends horizontally and is disposed obliquely above the opening side of the pressing device 100. The first guide rail 1 is disposed on the upper surface of the guide rail mounting plate 11 along its length direction. The first drive mechanism 4 drives the first clamping assembly 2 and the second clamping assembly 3 to reciprocate along the first guide rail 1 to place the flexible circuit board to be pressed into the pressing device 100 and to remove the pressed flexible circuit board from the pressing device 100.

[0074] It is worth noting that the pressing device 100 can be one unit or multiple units. When the pressing device 100 includes multiple units, the multiple pressing devices 100 are placed side by side, and the first guide rail 1 extends along the side by side, thereby enabling automatic material loading and unloading among the multiple pressing devices 100.

[0075] Optionally, in this embodiment, to facilitate the placement of the flexible circuit board being pressed, a placement platform 5 is provided in front of the opening side of the pressing device 100. More preferably, the height of the placement platform 5 is the same as the height of the upper surface of the first hot pressing assembly 101.

[0076] Furthermore, the first guide rail 1 is the first rack;

[0077] The first drive mechanism includes a first drive motor 41 and a first gear. The first gear meshes with a first rack and is rotatably fixed on the first clamping assembly 2. The output end of the first drive motor 41 is connected to the first gear to drive the first gear to rotate.

[0078] The second drive mechanism includes a second drive motor 42 and a second gear. The second gear meshes with the first rack and is rotatably fixed on the second clamping assembly 3. The output end of the second drive motor 42 is connected to the second gear to drive the second gear to rotate.

[0079] The first drive motor 41 drives the first gear to move along the length of the first rack, thereby driving the first clamping assembly 2 to reciprocate along the first guide rail 1. The second drive motor 42 drives the second gear to move along the length of the first rack, thereby driving the second clamping assembly 3 to reciprocate along the first guide rail 1. This enables the smooth movement of the first clamping assembly 2 and the second clamping assembly 3.

[0080] Furthermore, such as Figures 2 to 4 As shown, the first clamping assembly 2 includes:

[0081] The first mounting plate 21 and the first drive motor 41 are mounted on the first mounting plate 21;

[0082] First support 22;

[0083] The third drive mechanism 25 is disposed on the first mounting plate 21 and connected to the first bracket 22 to drive the first bracket 22 in the front-rear direction of the pressing device 100 (e.g., Figure 2 It moves back and forth along the z-direction (as shown in the middle), and the forward and backward direction is perpendicular to the horizontal direction of the extension of the first guide rail 1.

[0084] The first connecting arm 23 is connected to the lower end of the first bracket 22;

[0085] The first clamping mechanism 24 is disposed on the first connecting arm 23 and is used to clamp and press the flexible circuit board.

[0086] like Figure 5 and Figure 6 As shown, the second clamping assembly 3 includes:

[0087] The second mounting plate 31 and the second drive motor 42 are mounted on the second mounting plate 31;

[0088] Second support 32;

[0089] The fourth drive mechanism 35 is disposed on the second mounting plate 31 and connected to the second bracket 32 ​​to drive the second bracket 32 ​​to reciprocate in the front-back direction;

[0090] The second connecting arm 33 is connected to the lower end of the second bracket 32;

[0091] The second clamping mechanism 34 is disposed on the second connecting arm 33 and is used to clamp the flexible circuit board to be pressed.

[0092] Specifically, the first mounting plate 21 is rectangular and is positioned above the first guide rail 1. A first drive motor 41 is fixed to one end of the first mounting plate 21. The drive end of the first drive motor 41 is connected to a first gear, which meshes with a first rack. When the first drive motor 41 drives the first gear to rotate, the first gear moves along the length of the first rack, thereby causing the first mounting plate 21 to reciprocate along the length of the first rack.

[0093] A third drive mechanism 25 is fixed above the first mounting plate 21. The first bracket 22 is bent and includes a first horizontal portion located above the first mounting plate 21 and a first vertical portion connected to one end of the first horizontal portion. The two are fixedly connected and form a 90-degree angle. The third drive mechanism 25 is connected to the first horizontal portion of the first bracket 22, and a first connecting arm 23 is connected to the lower end of the first vertical portion of the first bracket 22. A first clamping mechanism 24 is provided on the first connecting arm 23. The third drive mechanism 25 drives the first bracket 22 to move in the front-back direction, thereby causing the first connecting arm 23 to move in the front-back direction. This causes the first clamping mechanism 24 to extend between the lower hot press plate of the first hot press assembly 101 and the upper hot press plate of the second hot press assembly 102, clamping the flexible circuit board pressed between them.

[0094] The second mounting plate 31 is rectangular and is positioned above the first guide rail 1. A second drive motor 42 is fixed to one end of the second mounting plate 31. The drive end of the second drive motor 42 is connected to a second gear, which meshes with the first rack. When the second drive motor 42 drives the second gear to rotate, the second gear moves along the length of the first rack, thereby causing the second mounting plate 31 to reciprocate along the length of the first rack.

[0095] A fourth drive mechanism 35 is fixed above the second mounting plate 31. The second bracket 32 ​​is also bent, including a second horizontal portion located above the second mounting plate 31 and a second vertical portion connected to one end of the second horizontal portion, the two being fixedly connected at a 90-degree angle. The fourth drive mechanism 35 is connected to the second horizontal portion of the second bracket 32, and the second connecting arm 33 is connected to the lower end of the second vertical portion of the second bracket 32. The second connecting arm 33 is provided with a second clamping mechanism 34. The fourth drive mechanism 35 drives the second bracket 32 ​​to move in the front-back direction, thereby driving the second connecting arm 33 to move in the front-back direction, so that the second clamping mechanism 34 extends between the lower hot pressing plate of the first hot pressing assembly 101 and the upper hot pressing plate of the second hot pressing assembly 102, placing the flexible circuit board to be pressed between them.

[0096] This avoids the need for operators to manually insert and remove flexible circuit boards, preventing warping and deformation of the edges of the flexible circuit boards, and improving production yield and efficiency.

[0097] Furthermore, the first clamping mechanism 24 includes two, which are spaced apart in the horizontal direction and are respectively located at both ends of the first connecting arm 23;

[0098] The first clamping mechanism 24 includes a first upper clamping plate 241, a first lower clamping plate 242, and a third drive motor 243. The fixed end of the third drive motor 243 is connected to the first connecting arm 23 and the first lower clamping plate 242, and the driving end of the third drive motor 243 is connected to the first upper clamping plate 241, so as to clamp the first upper clamping plate 241 in the vertical direction (e.g., ...). Figure 2 (As shown in the y-direction) The first upper clamping plate 241 is driven to reciprocate.

[0099] Specifically, in order to balance the clamping forces on both sides of the flexible circuit board, two first clamping mechanisms 24 are located near the outer side of the flexible circuit board and are smaller than the length of the flexible circuit board.

[0100] Optionally, in this embodiment, the third drive motor 243 is a stepper motor.

[0101] The first connecting arm 23 is inverted T-shaped, with its two lower ends connected to a first clamping mechanism 24, and its upper end connected to the lower end of the first vertical part of the first bracket 22. Both ends of the first connecting arm 23 are provided with motor mounting plates, on which a third drive motor 243 is fixed. The motor mounting plates have vertically extending grooves on both sides, with sliders mounted on the grooves. The drive end of the third drive motor 243 is connected to the sliders, and the first upper clamping plate 241 is fixed to the sliders. Under the driving action of the third drive motor 243, the sliders reciprocate along the grooves, thereby causing the first upper clamping plate 241 to reciprocate vertically, moving closer to and away from the first lower clamping plate 242.

[0102] In this embodiment, the first upper clamping plate 241 and the first lower clamping plate 242 are both rectangular plates, and an outwardly extending claw 244 is provided on the outermost side so that it can reach into the gap between the flexible circuit board and the hot press plate.

[0103] Preferably, the length of the claw portion 244 of the first lower clamping plate 242 is greater than the length of the claw portion 244 of the first upper clamping plate 241. Therefore, the first lower clamping plate 242 is more convenient for lifting the flexible circuit board.

[0104] Optionally, the third drive mechanism 25 includes a belt module 251, a first slide rail 252, a first slider 253, and a second slider 254. The belt module 251 includes a belt motor and a toothed belt. The toothed belt extends along the length direction (i.e., the front-to-back direction) of the first mounting plate 21 and is disposed on one side above the first mounting plate 21. The first slide rail 252 is disposed side-by-side with the toothed belt on the other side of the first mounting plate 21. The inner surface of the groove of the first slider 253 is provided with teeth for engaging with the toothed belt. The second slider 254 is slidably connected to the first slide rail 252, providing direction for the sliding of the second slider 254. The first slider 253 is fixedly connected to the upper part of the first horizontal section of the first bracket 22, and the second slider 254 is fixedly connected to the lower part of the first horizontal section of the first bracket 22. Thus, under the drive of the belt motor, the toothed belt and the first slider 253 drive the first horizontal section and the second slider 254 to slide, thereby realizing the reciprocating movement of the first clamping assembly 2 in the front-to-back direction. Therefore, it not only has a simple structure but also achieves high-speed transmission.

[0105] The fourth drive mechanism 35 has the same structure as the third drive mechanism 25, and will not be described in detail here.

[0106] Furthermore, the first mounting plate 21 has a first clearance hole 211 on the side facing the first bracket 22, and the second mounting plate 31 has a second clearance hole 311 on the side facing the second bracket 32, so as to avoid the first bracket 22 and the second bracket 32 ​​when they move. This provides movement space for the first bracket 22 and the second bracket 32 ​​to move back and forth, thereby reducing the size of the device.

[0107] Specifically, the first clearance hole 211 extends in the front-back direction and is disposed on one side of the first horizontal portion of the first mounting plate 21, and the second clearance hole 311 extends in the front-back direction and is disposed on one side of the second horizontal portion of the second mounting plate 31. Thus, when the first bracket 22 and the second bracket 32 ​​slide in the front-back direction, the first vertical portion can pass through the first mounting plate 21 and the second vertical portion can pass through the second mounting plate 31 without affecting the front-back movement of the first bracket 22 and the second bracket 32.

[0108] Furthermore, such as Figure 5 and Figure 7 As shown, the second clamping mechanism 34 includes a horizontally arranged fixed plate 341 and a finger cylinder 342 disposed below the fixed plate 341. One side of the fixed plate 341 is fixedly connected to the second connecting arm 33.

[0109] Specifically, the upper end of the second connecting arm 33 is connected to the second bracket 32, and the lower end of the second connecting arm 33 is fixedly connected to the middle position of one side of the fixing plate 341 and is located on the outside of the pressing device 100.

[0110] Thus, the edge of the flexible circuit board is clamped by the finger cylinder 342 to facilitate the clamping of the flexible circuit board, and the second clamping mechanism 34 will not collide with the hot pressing assembly when it extends between the first hot pressing assembly 101 and the second hot pressing assembly 102.

[0111] Optionally, in this embodiment, the finger cylinders 342 include five, which are respectively disposed at the four corners of the fixing plate 341 and on the side of the fixing plate 341 that is connected to the second connecting arm 33.

[0112] Specifically, five finger cylinders 342 are respectively positioned at the four corners of the fixing plate 341 and on the side connected to the second connecting arm 33. This prevents indentations on the flexible circuit board during handling and transportation, ensuring product quality.

[0113] It is worth noting that in other embodiments, the number and position of the finger cylinders can be set according to specific needs. Furthermore, the structures of each finger cylinder can be the same or different, depending on the specific requirements.

[0114] Furthermore, the first clamping assembly 2 also includes a fifth driving mechanism 26, which is disposed on the first bracket 22. The driving end of the fifth driving mechanism 26 is connected to the first connecting arm 23 to drive the first connecting arm 23 to reciprocate in the vertical direction.

[0115] The second clamping assembly 3 also includes a sixth driving mechanism 36, which is disposed on the second bracket 32. The driving end of the sixth driving mechanism 36 is connected to the second connecting arm 33 to drive the second connecting arm 33 to reciprocate in the vertical direction.

[0116] This allows the first connecting arm 23 and the second connecting arm 33 to descend to a designated position for picking up and placing the flexible circuit board.

[0117] Optionally, the fifth drive mechanism 26 includes a servo motor and a lead screw transmission unit. The lead screw transmission unit includes a lead screw arranged vertically and a third slider threadedly connected to the lead screw. The servo motor is fixed to the first bracket 22, and its drive end is connected to one end of the lead screw. When the servo motor drives the lead screw to rotate, the third slider can slide up and down along the lead screw in the vertical direction. The third slider is connected to the first connecting arm 23, thereby driving the first connecting arm 23 to reciprocate in the vertical direction, which in turn can lower or raise the first clamping mechanism 24 to a designated position. By controlling the number of rotations of the lead screw, the distance of the first connecting arm 23 lowering and raising is controlled. This technical solution provides smooth transmission and improves the accuracy of moving the first connecting arm 23.

[0118] The sixth drive mechanism 36 has the same structure as the fifth drive mechanism 26, and will not be described in detail here.

[0119] Furthermore, the first bracket 22 is provided with a first photoelectric detection unit (not shown) for detecting whether the second hot-pressing assembly 102 has been opened to a predetermined position.

[0120] Optionally, the predetermined position is that the opening distance between the first hot-pressing assembly 101 and the second hot-pressing assembly 102 is 2cm.

[0121] Specifically, the first photoelectric detection unit is disposed on the first connecting arm 23. When the second hot-pressing assembly 102 rotates relative to the first hot-pressing assembly 101, the second hot-pressing assembly 102 can be opened or closed. The opening distance of the second hot-pressing assembly 102 relative to the first hot-pressing assembly 101 varies depending on the pressing device. Since one edge of the upper hot-pressing plate moves away from the lower hot-pressing plate when the second hot-pressing assembly 102 is opened, if the opening is too large, the position of the flexible circuit board will not be fixed. Therefore, in this embodiment, the opening distance is set to 2cm, which can fix the position of the flexible circuit board. At this time, the flexible circuit board can be accurately located by the second clamping assembly 3, thereby successfully removing the flexible circuit board.

[0122] Specifically, in this embodiment, when the first connecting arm 23 descends to the point where the first photoelectric detection unit detects the edge of the upper cover of the second hot-pressing assembly 102, it descends a predetermined distance according to the thickness of the upper cover. For example, if the thickness of the upper cover is 5cm, the first connecting arm 23 descends 5cm after finding the edge of the upper cover, thereby accurately finding the position of the flexible circuit board.

[0123] Furthermore, the first bracket 22 is also equipped with a vision detection unit (not shown) for detecting whether the first clamping mechanism 24 is clamping and pressing the flexible circuit board.

[0124] Specifically, the visual inspection unit is a CCD camera, mounted on the first support 22. After clamping, it acquires an image below the first clamping assembly 2 to determine whether the first clamping mechanism 24 is holding the flexible circuit board, thus determining whether a flexible circuit board has been clamped out. More specifically, after the first clamping mechanism 24 clamps out the flexible circuit board, it moves backward above the placement platform 5 and places the clamped flexible circuit board on the placement platform 5. At this time, the CCD camera takes a picture of the product on the placement platform 5, and by confirming whether there is a flexible circuit board on the placement platform 5, it determines whether the flexible circuit board has been clamped out.

[0125] Furthermore, it also includes an alarm device and a control unit, both of which are electrically connected to the control unit. The vision detection unit acquires an image of the area in front of the first clamping mechanism 24 and sends it to the control unit. The control unit determines whether the first clamping mechanism 24 is holding the flexible circuit board based on the acquired image. If it is determined that the flexible circuit board is not being held, the control unit sends an alarm signal to the alarm device to issue an alert. This allows for timely notification to personnel that the first clamping mechanism 24 has failed to retrieve the flexible circuit board.

[0126] In this embodiment, after the pressing operation is completed, the second hot pressing assembly 102 is rotated upward to a position 2cm away from the outer edge of the first hot pressing assembly 101. The first drive motor 41 drives the first gear to move along the first rack, thereby driving the first clamping assembly 2 to reciprocate in the horizontal direction. The fifth drive mechanism 26 drives the first connecting arm 23 to descend. When the first photoelectric detection unit detects the top cover, it continues to descend by 5cm (the thickness of the top cover). The third drive mechanism 25 drives the first bracket 22 to move forward a first predetermined distance, thereby driving the first connecting arm 23 and the first clamping mechanism 24 to move forward to the open position of the first hot pressing assembly 101 and the second hot pressing assembly 102, so that the first clamping mechanism 24 can be inserted between the first hot pressing assembly 101 and the second hot pressing assembly 102. During the insertion of the first clamping mechanism 24, the first lower clamping plate 242 lifts up the flexible circuit board (which is covered with protective film on both the upper and lower layers) from the bottom layer. The first upper clamping plate 241 descends to form a clamping force with the first lower clamping plate 242, thereby clamping the flexible circuit board. After the first upper clamping plate 241 and the first lower clamping plate 242 clamp the flexible circuit board, the third driving mechanism 25 drives the first clamping assembly 2 to move backward a first predetermined distance to above the placement platform 5 on the front side of the pressing device 100. Simultaneously, the second hot-pressing assembly 102 also fully opens to a position where the distance between the second hot-pressing assembly 102 and the outer edge of the first hot-pressing assembly 101 is 25 cm (the fully open position of the second hot-pressing assembly 102 and the first hot-pressing assembly 101). The first upper clamping plate 241 of the first clamping mechanism 24 returns to its initial position to release the flexible circuit board. The fourth driving mechanism 35 drives the first clamping assembly 2 to move upward to its initial height. The visual inspection unit takes a picture of the placement platform 5 below. If the visual inspection unit does not detect the flexible circuit board, the alarm device will sound an alarm. If the visual inspection unit detects the flexible circuit board, the first drive motor 41 drives the first clamping assembly 2 to move along the first guide rail 1 to move away from the pressing device 100 to the waiting position. At the same time, the second drive motor 42 drives the second gear to move along the first rack, thereby driving the second clamping assembly 3 to move horizontally to the pressing device 100. That is, the finger cylinder 342 of the second clamping assembly 3 clamps the flexible circuit board to be pressed from the previous process and moves it along the first guide rail 1 to the top of the placement platform 5. After the sixth drive mechanism 36 drives the second connecting arm 33 to descend a third predetermined distance, the fourth drive mechanism 35 drives the second bracket 32 ​​to move forward a second predetermined distance, thereby driving the second connecting arm 33 and the second clamping mechanism 34 to move forward to above the first hot pressing assembly 101, so as to place the flexible circuit board to be pressed on the first hot pressing assembly 101. Then the fourth drive mechanism 35 drives the second bracket 32 ​​to move backward a second predetermined distance to above the placement platform 5.The second hot-pressing assembly 102 rotates downwards and closes with the first hot-pressing assembly 101 to begin the pressing operation.

[0127] In this embodiment, after the second clamping assembly 3 places the flexible circuit board into the pressing device 100, it moves backward to above the placement platform 5. The sixth drive mechanism 36 drives the second support 32 to move downward a fourth predetermined distance, and the finger cylinder 342 clamps the pressed flexible circuit board placed on the placement platform 5. The sixth drive mechanism 36 drives the second support 32 to move upward to the initial height, and the second drive motor 42 drives the second clamping assembly 3 to move along the first guide rail 1 to the designated device, thereby placing the pressed flexible circuit board in the designated position.

[0128] The automatic material handling device provided by this utility model can replace the existing manual material handling operation, and can quickly and accurately carry out material handling operations, realizing the automation of production. It not only saves manpower and improves production efficiency, but also ensures the quality of the produced products.

[0129] like Figure 1 As shown, an embodiment of this utility model also provides a pressing system, comprising:

[0130] The pressing device 100 includes a first hot pressing assembly 101 and a second hot pressing assembly 102 rotatably connected to one side of the first hot pressing assembly 101.

[0131] The automatic loading and unloading device described above is used to place the flexible circuit board to be pressed into the pressing device 100 and to remove the pressed flexible circuit board from the pressing device 100.

[0132] Furthermore, in this embodiment, it also includes:

[0133] Separation device 200, located on one side of pressing device 100, is used to separate the upper protective film on the pressed flexible circuit board from the flexible circuit board.

[0134] The above technical solution enables the automatic separation of the protective film from the flexible circuit board being pressed, thereby improving production efficiency.

[0135] Specifically, the pressing system may include multiple pressing devices 100 arranged side by side. The separating device 200 may be located on one side of the multiple pressing devices 100 or in the middle of the multiple pressing devices 100. This utility model does not impose any restrictions on this and can be set according to actual production needs. In this embodiment, the separating device 200 is located in the middle of the multiple pressing devices 100 and is arranged side by side with the pressing devices 100, and the first guide rail 1 extends above the multiple pressing devices 100 and the separating device 200.

[0136] Furthermore, such as Figure 8 and Figure 9 As shown, the separation device 200 includes:

[0137] Separation platform 201 is used to place the flexible circuit board that is pressed against the plate;

[0138] The suction arm assembly includes:

[0139] The third mounting plate 202 is provided with a second guide rail 203, which extends in the front-back direction and is perpendicular to the extension direction of the first guide rail 1.

[0140] The third bracket 204, one end of which is movably connected to the second guide rail 203;

[0141] The seventh drive mechanism 205 is mounted on the third mounting plate 202 and connected to the third bracket 204 to drive the third bracket 204 to reciprocate along the second guide rail 203.

[0142] The third connecting arm 206 is movably connected to the other end of the third bracket 204, and a suction cup 207 is provided below the third connecting arm 206.

[0143] Specifically, the separation platform 201 is disposed beside the pressing device 100 and located next to its first hot pressing assembly 101. Optionally, the height of the separation platform 201 is the same as the height of the upper surface of the first hot pressing assembly 101.

[0144] The third mounting plate 202 is horizontally positioned below the first guide rail 1. A second guide rail 203 is positioned below the third mounting plate 202, extending in a front-back direction perpendicular to the first guide rail 1.

[0145] The seventh drive mechanism 205 includes a belt module, a fourth slider, and a fifth slider. The belt module includes a belt motor and a toothed belt. The toothed belt extends along the length of the third mounting plate 202 and is positioned at the middle of the third mounting plate 202. Two second guide rails 203 are arranged side-by-side with the toothed belt on both sides of the third mounting plate 202. The inner surface of the groove of the fourth slider is toothed for engaging with the toothed belt. The third support 204 includes a third horizontal section and a third vertical section connected to one end of the third horizontal section. The two sections are fixedly connected and form a 90-degree angle. The third vertical section is located at the distal end opposite to the first clamping assembly 2 or the second clamping assembly 3. The third horizontal section connects the fourth slider and the fifth slider. The fifth slider is slidably connected to the second guide rail 203, providing direction for the movement of the third support 204. Driven by the belt motor, the toothed belt drives the fourth slider, the fifth slider, and the second horizontal section to slide in the front-back direction, thereby realizing the reciprocating movement of the suction arm assembly in the front-back direction. This not only results in a simple structure but also enables high-speed transmission.

[0146] Furthermore, in this embodiment, the second clamping assembly 3 is also used to transport the pressed flexible circuit board to the separation platform 201.

[0147] Specifically, after the first clamping assembly 2 places the flexible circuit board on the placement platform 5, the second clamping assembly 3 clamps and presses the flexible circuit board and moves it along the first guide rail 1 to the separation device 200, so that the upper protective film of the flexible circuit board can be separated by the separation device 200.

[0148] Furthermore, in this embodiment, it also includes:

[0149] The eighth drive mechanism (not shown) is connected to the separation platform 201 to drive the separation platform 201 to reciprocate vertically; and / or,

[0150] The ninth drive mechanism is mounted on the third bracket 204. The drive end of the ninth drive mechanism 209 is connected to the third connecting arm 206 to drive the third connecting arm 206 to reciprocate in the vertical direction.

[0151] The separation platform 201 is driven to reciprocate vertically by the eighth drive mechanism, thereby allowing multiple flexible circuit boards with pressing plates to be stored on the separation platform 201. Specifically, each time a flexible circuit board with pressing plates is placed on the separation platform 201, the separation platform 201 will descend a predetermined distance to ensure that the height of the top layer of flexible circuit boards remains consistent.

[0152] Specifically, the eighth drive mechanism includes a cylinder, the drive end of which is connected to the middle of the separation platform 201.

[0153] The third connecting arm 206 is lowered a seventh predetermined distance by the ninth drive mechanism 209, so that the suction cup 207 contacts the uppermost protective film and removes it. In this embodiment, the seventh predetermined distance is 100mm. Of course, the seventh distance can be set according to actual needs.

[0154] Optionally, the ninth drive mechanism 209 includes a motor, a vertically arranged lead screw, and a sixth slider. The drive end of the motor is connected to one end of the lead screw, and the sixth slider is threadedly connected to the lead screw and fixedly connected to the third connecting arm 206. When the motor drives the lead screw to rotate, the sixth slider reciprocates along the length of the lead screw, thereby driving the third connecting arm 206 and the suction cup 207 below to reciprocate in the vertical direction.

[0155] Optionally, a second photoelectric detection unit is provided at a position above the separation platform 201 at the same height as the upper surface of the first hot-pressing assembly 101 to ensure that the height of the top flexible circuit board remains consistent.

[0156] Furthermore, the suction cup 207 is equipped with a metal detection unit 208, which is used to detect whether the protective film is separated from the flexible circuit board.

[0157] In this embodiment, a metal detection unit 208 is provided on each side of the suction cup 207. The detection results of the two detection units are used to make a judgment, which can ensure accurate detection.

[0158] Specifically, since the protective film is usually made of metal, a metal detection unit 208 is provided on the suction cup 207. This unit can be used to detect whether the object on the suction cup 207 is a flexible circuit board or a protective film, thereby determining whether the protective film has separated from the flexible circuit board. For example, if the metal detection unit 208 detects a signal, it indicates that the protective film has separated from the flexible circuit board; otherwise, if no signal is detected, it means that the protective film has not separated from the flexible circuit board.

[0159] In this embodiment, after the second clamping assembly 3 clamps the flexible circuit board pressed against the placement platform 5, the second clamping assembly 3 moves along the first guide rail 1 to the separation device 200, and the third drive mechanism 35 drives the second support 32 to move forward above the separation platform 201. The finger cylinder 342 releases the flexible circuit board, and the flexible circuit board is placed on the separation platform 201. The separation platform 201 descends a sixth predetermined distance, and the second clamping assembly 3 moves backward. At the same time, the seventh drive mechanism 205 drives the third support 204 to move forward a fifth predetermined distance, and the suction cup 207 is positioned above the flexible circuit board. The ninth drive mechanism 209 drives the third connecting arm 206 to move downward a seventh predetermined distance, thereby causing the suction cup 207 to suck up the protective film on the flexible circuit board. The ninth drive mechanism 209 drives the third connecting arm 206 to move upward a seventh predetermined distance, thereby separating the protective film from the flexible circuit board. In addition, two metal detection units 208 provided on the suction cup 207 are used to detect whether there is a protective film on the product on the suction cup 207, thereby determining whether the protective film has been separated from the flexible circuit board.

[0160] The pressing system provided by this utility model replaces manual operation, realizes automatic separation of protective film and flexible circuit board, and improves production efficiency.

[0161] Furthermore, the above embodiments of this utility model are merely illustrative of the principles and effects of this utility model, and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
