Description

Technical Field

[0001] The invention relates to the technical field of flexible circuit board processing equipment, and in particular to an automatic material taking and placing device for a crimping device and a crimping system. Background Art

[0002] Flexible Printed Circuit (FPC) is a printed circuit board with high reliability and excellent flexibility. It is highly favored for its excellent characteristics such as light weight, thin thickness, easy installation, and free bending and folding. By embedding circuit design on a bendable and thin plastic sheet, a large number of precision components can be stacked in a narrow and limited space, thus forming a bendable flexible circuit.

[0003] At present, a layer of protective film is attached to the top and bottom of the flexible circuit board for crimping. The purpose of crimping the flexible circuit board is: first, to enhance the adhesion between the protective film and the flexible circuit board; second, to prevent abnormal testing of the reliability of the filler material; third, to facilitate the stability of the electrical performance of the flexible circuit board. The crimping operation is carried out by a crimping device, which mainly uses high-temperature sealing to make the filler material - the crimping protective film, adhere to the surface of the flexible circuit board. The internal hot plate of the crimping device is mainly made of base materials such as silicone and glass fiber cloth, with excellent sealing, which can reduce bubbles and overflowing glue during operation to achieve its function.

[0004] However, the existing crimping process still relies on manual material picking and placing during the production process. Manual picking and placing of flexible circuit boards not only increases production costs and reduces production efficiency, but also the temperature of the crimping device during the crimping process is as high as 175°C. The high temperature causes the crimping protective film and the flexible circuit board to adhere tightly to the hot plate surface of the crimping device. Since the crimped flexible circuit board needs to be manually separated and taken out, if it is not picked up manually, the edge of the flexible circuit board will be warped, affecting the production yield.

[0063] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0064] Now, exemplary embodiments of the present invention are described with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms used in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0065] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0066] like Figure 1 As shown, an embodiment of the present invention provides an automatic material loading and unloading device for a crimping device 100. The crimping 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, and the lower hot pressing plate is used to carry the flexible circuit board to be crimped; 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] The upper and lower surfaces of the flexible circuit board to be pressed are provided with protective films respectively. When the second hot pressing assembly 102 is closed with the first hot pressing assembly 101, the flexible circuit board placed therein can be pressed by the upper hot pressing plate and the lower hot pressing plate, that is, protective films are attached to both surfaces of the flexible circuit board.

[0068] In this embodiment, the automatic material taking and placing device includes:

[0069] The first guide rail 1 is arranged along a horizontal direction (such as Figure 1 (shown in the x direction) is arranged above the crimping device 100;

[0070] The first clamping assembly 2 and the second clamping assembly 3 are arranged on one side of the first hot pressing assembly 101 and the second hot pressing assembly 102 of the crimping device 100 and are movably connected to the first guide rail 1. The first clamping assembly 2 is used to clamp the crimped flexible circuit board, and the second clamping assembly 3 is used to clamp the flexible circuit board to be crimped.

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

[0072] Specifically, the flexible circuit board to be crimped is placed into the crimping device 100 through the second clamping component 3. After the crimping operation of the crimping device 100 is completed, the first clamping component 2 clamps the crimped flexible circuit board and takes it out of the crimping device 100. Therefore, the operation of placing and taking out the flexible circuit board does not need to be completed manually by the operator, which avoids warping and deformation of the edge of the flexible circuit board, improves the production yield, and because it can realize automatic loading and unloading, the operation is more convenient and efficient, which improves production efficiency and reduces production costs.

[0073] In this embodiment, the guide rail mounting plate 11 extends in the horizontal direction and is disposed obliquely above the opening side of the crimping 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 driving 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 crimped into the crimping device 100 and take the crimped flexible circuit board out of the crimping device 100.

[0074] It is worth noting that the crimping device 100 may be one or more. When the crimping device 100 includes more than one, the plurality of crimping devices 100 are placed side by side, and the first guide rail 1 is extended along the direction of the side-by-side placement, so that the material can be automatically taken and put between the plurality of crimping devices 100.

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

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

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

[0078] The second driving mechanism includes a second driving motor 42 and a second gear. The second gear is meshed with the first rack and rotatably fixed to the second clamping assembly 3. The output end of the second driving 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 direction of the first rack, thereby driving the first clamping assembly 2 to reciprocate along the first guide rail 1, and the second drive motor 42 drives the second gear to move along the length direction of the first rack, thereby driving the second clamping assembly 3 to reciprocate along the first guide rail 1, thereby achieving smooth movement of the first clamping assembly 2 and the second clamping assembly 3.

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

[0081] A first mounting plate 21, on which a first driving motor 41 is disposed;

[0082] A first bracket 22;

[0083] The third driving mechanism 25 is disposed on the first mounting plate 21 and connected to the first bracket 22 to drive the first bracket 22 to move in the front-to-back direction (eg Figure 2 The front-to-rear direction is perpendicular to the horizontal direction in which the first guide rail 1 extends;

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

[0085] A first clamping mechanism 24 is provided on the first connecting arm 23 and is used to clamp the pressed flexible circuit board;

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

[0087] A second mounting plate 31, on which a second driving motor 42 is disposed;

[0088] A second bracket 32;

[0089] A fourth driving mechanism 35, which is disposed on the second mounting plate 31 and connected to the second bracket 32, so as to drive the second bracket 32 ​​to reciprocate in the front-rear direction;

[0090] A second connecting arm 33 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 in the shape of a rectangular plate and is disposed above the first guide rail 1. A first drive motor 41 is fixed to one end of the first mounting plate 21, and a drive end of the first drive motor 41 is connected to a first gear, and the first gear is meshed with a first rack. When the first drive motor 41 drives the first gear to rotate, the first gear moves along the length direction of the first rack, thereby driving the first mounting plate 21 to reciprocate along the length direction of the first rack.

[0093] A third driving mechanism 25 is fixed above the first mounting plate 21. The first bracket 22 is bent, including 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 being fixedly connected and forming an angle of 90 degrees. Among them, the third driving mechanism 25 is connected to the first horizontal portion of the first bracket 22, the first connecting arm 23 is connected to the lower end of the first vertical portion of the first bracket 22, and the first connecting arm 23 is provided with a first clamping mechanism 24. The third driving mechanism 25 drives the first bracket 22 to move in the front-to-back direction, thereby driving the first connecting arm 23 to move in the front-to-back direction, so that the first clamping mechanism 24 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, and clamps the pressed flexible circuit board out from between the two.

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

[0095] A fourth driving 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 and forming an angle of 90 degrees. Among them, the fourth driving mechanism 35 is connected to the second horizontal portion of the second bracket 32, the second connecting arm 33 is connected to the lower end of the second vertical portion of the second bracket 32, and the second connecting arm 33 is provided with a second clamping mechanism 34. The fourth driving mechanism 35 drives the second bracket 32 ​​to move in the front-to-back direction, thereby driving the second connecting arm 33 to move in the front-to-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, and the flexible circuit board to be pressed is placed between the two.

[0096] This can avoid the operator manually putting in and taking out the flexible circuit board, prevent the edge of the flexible circuit board from warping and deforming, and improve the production yield and production efficiency.

[0097] Furthermore, the first clamping mechanism 24 includes two, which are arranged at intervals in the horizontal direction and are respectively arranged 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. The driving end of the third drive motor 243 is connected to the first upper clamping plate 241 to adjust the clamping mechanism 24 in the vertical direction (such as Figure 2 The first upper clamping plate 241 is driven to move reciprocally (as shown in the y direction).

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

[0100] Optionally, in this embodiment, the third driving motor 243 is a stepping motor.

[0101] The first connecting arm 23 is in an inverted T-shape, and the two lower ends are respectively connected to the first clamping mechanism 24, and the upper part thereof is used to connect with the lower end of the first vertical portion of the first bracket 22. Motor mounting plates are respectively provided at both ends of the first connecting arm 23, and the third driving motor 243 is fixed to the motor mounting plate. A slide groove extending in the vertical direction is provided on both sides of the motor mounting plate, and a slider is provided on the slide groove. The driving end of the third driving motor 243 is connected to the slider, and the first upper clamping plate 241 is fixed to the slider. Under the driving action of the third driving motor 243, the slider is driven to reciprocate along the slide groove, thereby driving the first upper clamping plate 241 to reciprocate in the vertical direction to approach and move 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 are provided with outwardly extending claws 244 on the outermost sides so as to be able to extend into the gap between the flexible circuit board and the heat pressing 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. Thus, the first lower clamping plate 242 is more convenient to lift the flexible circuit board.

[0104] Optionally, the third driving mechanism 25 includes a belt module 251, a first slideway 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 is extended along the length direction (i.e., the front-to-back direction) of the first mounting plate 21 and arranged on one side above the first mounting plate 21, and the first slideway 252 and the toothed belt are arranged side by side on the other side of the first mounting plate 21. The inner surface of the slideway 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 slideway 252 to provide a direction for the sliding of the second slider 254. The first slider 253 is fixedly connected to the upper part of the first horizontal part of the first bracket 22, and the second slider 254 is fixedly connected to the lower part of the first horizontal part of the first bracket 22, so that under the driving action of the belt motor, the first horizontal part and the second slider 254 are driven to slide through the toothed belt and the first slider 253, thereby realizing the reciprocating movement of the first clamping assembly 2 in the front-to-back direction. As a result, not only the structure is simple, but also high-speed transmission can be achieved.

[0105] The structure of the fourth driving mechanism 35 is the same as that of the third driving mechanism 25 and will not be described in detail herein.

[0106] Furthermore, the first mounting plate 21 is provided with a first avoidance hole 211 on a side facing the first bracket 22, and the second mounting plate 31 is provided with a second avoidance hole 311 on a side facing the second bracket 32, so as to avoid the first bracket 22 and the second bracket 32 ​​when the first bracket 22 and the second bracket 32 ​​move. Thus, a moving space can be provided for the forward and backward movement of the first bracket 22 and the second bracket 32, thereby reducing the size of the device.

[0107] Specifically, the first avoidance hole 211 extends in the front-to-back direction and is arranged on one side of the first horizontal portion of the first mounting plate 21, and the second avoidance hole 311 extends in the front-to-back direction and is arranged on one side of the second horizontal portion of the second mounting plate 31, so that when the first bracket 22 and the second bracket 32 ​​slide in the front-to-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-to-back movement of the first bracket 22 and the second bracket 32.

[0108] Furthermore, if Figure 5 and Figure 7 As shown, the second clamping mechanism 34 includes a horizontally arranged fixing plate 341 and a finger cylinder 342 arranged below the fixing plate 341 , and one side of the fixing 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 outside relative to the crimping device 100 .

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

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

[0112] Specifically, the five finger cylinders 342 are respectively disposed at the four corners of the fixing plate 341 and at the position of the side connected to the second connecting arm 33. Thus, the flexible circuit board is prevented from being indented during the process of picking up and carrying the flexible circuit board, thereby 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. In addition, the structures of the finger cylinders can be the same or different, and can be set according to specific needs.

[0114] Furthermore, the first material clamping assembly 2 further includes a fifth driving mechanism 26, which is disposed on the first bracket 22, and a 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 material clamping assembly 3 further includes a sixth driving mechanism 36 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] Thus, the first connecting arm 23 and the second connecting arm 33 can be lowered to a designated position to take and place the flexible circuit board.

[0117] Optionally, the fifth driving mechanism 26 includes a servo motor and a screw transmission unit. The screw transmission unit includes a screw arranged in the vertical direction and a third slider threadedly connected to the screw. The servo motor is fixed to the first bracket 22, and its driving end is connected to one end of the screw. When the servo motor drives the screw to rotate, the third slider can slide up and down along the 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, and then the first clamping mechanism 24 can be lowered or raised to a specified position. By controlling the number of turns of the screw, the distance of the first connecting arm 23 to be lowered and raised is controlled. With this technical solution, the transmission is smooth and the accuracy of moving the first connecting arm 23 can be improved.

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

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

[0120] Optionally, the predetermined position is that the opening distance of the first hot pressing assembly 101 relative to the second hot pressing assembly 102 is 2 cm.

[0121] Specifically, the first photoelectric detection unit is arranged 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 will be different for different pressing devices. Since when the second hot pressing assembly 102 is opened, one side edge of the upper hot pressing plate moves away from the lower hot pressing plate, if it is opened too much, the position of the flexible circuit board will not be fixed. Therefore, in this embodiment, the opening distance is set to 2cm, so that the position of the flexible circuit board can be fixed. At this time, the flexible circuit board is clamped by the second clamping assembly 3, and the flexible circuit board that has been pressed can be accurately found, so that the flexible circuit board can be successfully removed.

[0122] Specifically, in this embodiment, the first connecting arm 23 descends until the first photoelectric detection unit detects the edge of the upper cover of the second hot pressing assembly 102, and then descends a predetermined distance according to the thickness of the upper cover. For example, the thickness of the upper cover is 5 cm, that is, after finding the edge of the upper cover, the first connecting arm 23 descends 5 cm, so that the position of the flexible circuit board can be accurately found.

[0123] Furthermore, a visual inspection unit (not shown) is provided on the first bracket 22 for inspecting whether the first clamping mechanism 24 clamps the pressed flexible circuit board.

[0124] Specifically, the visual inspection unit is a CCD camera, which is arranged on the first bracket 22, and is used to determine whether the first clamping mechanism 24 clamps the flexible circuit board by acquiring the image below the first clamping component 2 after the clamping is completed, so as to judge whether the flexible circuit board is clamped out. More specifically, after the first clamping mechanism 24 clamps out the flexible circuit board, it moves backward to the top of the placement platform 5, and places the pressed flexible circuit board on the placement platform 5. At this time, the CCD camera is used to take 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 is judged whether the flexible circuit board is clamped out.

[0125] Furthermore, it also includes an alarm device and a control unit, and the alarm device and the visual detection unit are both electrically connected to the control unit. The visual detection unit obtains an image in front of the first clamping mechanism 24 and sends it to the control unit, and the control unit determines whether the first clamping mechanism 24 clamps the flexible circuit board based on the obtained image. If it is determined that the flexible circuit board is not clamped, the control unit sends an alarm signal to the alarm device to alarm. In this way, the staff can be reminded in time that the first clamping mechanism 24 has not taken 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 2 cm away from the outer edge of the first hot pressing assembly 101, and 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, and the fifth drive mechanism 26 drives the first connecting arm 23 to descend. When the first photoelectric detection unit detects the upper cover, it continues to descend by 5 cm (the thickness of the upper cover), and 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 as to extend the first clamping mechanism 24 between the first hot pressing assembly 101 and the second hot pressing assembly 102. During the process of the first clamping mechanism 24 extending, the first lower clamping plate 242 picks up the flexible circuit board pressed from the bottom layer (the upper and lower layers of the flexible circuit board pressed are covered with protective films), and the first upper clamping plate 241 descends to form a clamping force with the first lower clamping plate 242 to clamp 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 by a first predetermined distance to above the placement platform 5 on the front side of the pressing device 100. While the first clamping assembly 2 moves backward, the second hot pressing assembly 102 is also synchronously fully opened to a position where the distance between the outer edge of the second hot pressing assembly 102 and the first hot pressing assembly 101 is 25 cm (the position where the second hot pressing assembly 102 and the first hot pressing assembly 101 are fully opened). The first upper clamping plate 241 of the first clamping mechanism 24 returns to the initial position upward to release the flexible circuit board. The fourth driving mechanism 35 drives the first clamping assembly 2 to move upward to the initial height. The visual inspection unit takes a photo of the placement platform 5 below. If the visual inspection unit does not detect the flexible circuit board, the alarm device sounds an alarm; if the visual inspection unit detects a flexible circuit board, the first drive motor 41 drives the first clamping assembly 2 to move along the first guide rail 1 to leave the crimping device 100 here to the waiting position. At the same time, the second drive motor 42 drives the second gear to move along the first rack to drive the second clamping assembly 3 to move horizontally to the crimping device 100, that is, the finger cylinder 342 of the second clamping assembly 3 clamps the flexible circuit board to be crimped taken from the previous process and moves along the first guide rail 1 to the top of the placement platform 5. After the sixth driving mechanism 36 drives the second connecting arm 33 to descend the third predetermined distance, the fourth driving mechanism 35 drives the second bracket 32 ​​to move forward the 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, and then the fourth driving mechanism 35 drives the second bracket 32 ​​to move backward the second predetermined distance to above the placement platform 5.The second hot pressing assembly 102 rotates downward and closes with the first hot pressing assembly 101 to start the pressing operation.

[0127] In addition, in this embodiment, after the second clamping assembly 3 places the flexible circuit board in the crimping device 100, it moves backward to the top of the placement platform 5, and the sixth driving mechanism 36 drives the second bracket 32 ​​to move downward by a fourth predetermined distance, and the finger cylinder 342 clamps the crimped flexible circuit board placed on the placement platform 5. The sixth driving mechanism 36 drives the second bracket 32 ​​to move upward to the initial height, and the second driving motor 42 drives the second clamping assembly 3 to move along the first guide rail 1 to the designated device, thereby placing the crimped flexible circuit board at the designated position.

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

[0133] The separation device 200 is disposed on one side of the crimping device 100 and is used to separate the upper protective film on the crimped flexible circuit board from the flexible circuit board.

[0134] Through the above technical solution, the protective film can be automatically separated from the pressed flexible circuit board, thereby improving the production efficiency.

[0135] Specifically, the crimping system may include a plurality of crimping devices 100 arranged side by side. The separation device 200 may be arranged on one side of the plurality of crimping devices 100, or may be arranged in the middle of the plurality of crimping devices 100. The present invention does not limit this, and may be arranged according to actual production needs. In this embodiment, the separation device 200 is arranged in the middle of the plurality of crimping devices 100 and arranged side by side with the crimping devices 100, and the first guide rail 1 extends above the plurality of crimping devices 100 and the separation device 200.

[0143] Specifically, the separation platform 201 is disposed beside the pressing device 100 and is located beside the first hot pressing assembly 101. Optionally, the height of the separation platform 201 is consistent with the height of the upper surface of the first hot pressing assembly 101.

The inner surface of the slide groove of the fourth slider is provided with teeth for engaging with the toothed belt. The third bracket 204 includes a third horizontal portion and a third vertical portion connected to one end of the third horizontal portion, the two are fixedly connected and form an angle of 90 degrees, and the third vertical portion is arranged at the far end opposite to the first clamping assembly 2 or the second clamping assembly 3. The third horizontal portion connects the fourth slider and the fifth slider, and the fifth slider is slidably connected to the second guide rail 203 to provide a direction for the movement of the third bracket 204. Under the driving action of the belt motor, the toothed belt drives the fourth slider, the fifth slider and the second horizontal portion to slide in the front-to-back direction, thereby realizing the reciprocating movement of the suction arm assembly in the front-to-back direction. As a result, not only the structure is simple, but also high-speed transmission can be achieved.

[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 the pressed flexible circuit board and moves along the first guide rail 1 and moves to the separation device 200, so that the separation device 200 can be used to separate the upper protective film of the flexible circuit board.

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

[0149] an eighth driving mechanism (not shown), the eighth driving mechanism being connected to the separation platform 201 to drive the separation platform 201 to reciprocate in the vertical direction; and / or,

[0150] The ninth driving mechanism is disposed on the third bracket 204 . The driving end of the ninth driving 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 move back and forth in the vertical direction by the eighth driving mechanism, so that a plurality of pressed flexible circuit boards can be stored on the separation platform 201. That is, each time a pressed flexible circuit board is placed on the separation platform 201, the separation platform 201 will be lowered by a sixth predetermined distance to ensure that the height of the topmost layer of flexible circuit boards is always kept consistent.

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

[0153] The third connecting arm 206 is driven to descend by the ninth driving mechanism 209 to make the suction cup 207 contact the topmost protective film and suck it away. In this embodiment, the seventh predetermined distance is 100 mm. Of course, the seventh distance can be set according to actual needs.

[0154] Optionally, the ninth driving mechanism 209 includes a motor, a vertically arranged screw and a sixth slider, wherein the driving end of the motor is connected to one end of the screw, the sixth slider is threadedly connected to the screw and fixedly connected to the third connecting arm 206, and when the motor drives the screw to rotate, the sixth slider reciprocates along the length direction of the 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 above the separation platform 201 at a position consistent with the height of the upper surface of the first hot pressing assembly 101 to ensure that the height of the uppermost layer of the flexible circuit board always remains consistent.

[0156] Furthermore, a metal detection unit 208 is provided on the suction cup 207 for detecting 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, and judgment is made based on the detection results of the two detection units to 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 to detect whether the flexible circuit board or the protective film is on the suction cup 207, so as to determine whether the protective film is separated from the flexible circuit board. For example, if the metal detection unit 208 detects a signal, it means that the protective film is separated from the flexible circuit board; otherwise, if no signal is detected, the protective film is not separated from the flexible circuit board.

[0159] In this embodiment, after the second clamping assembly 3 clamps the pressed flexible circuit board on the placement platform 5, the second clamping assembly 3 moves along the first guide rail 1 to the separation device 200, and the third driving mechanism 35 drives the second bracket 32 ​​to move forward to the top of 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 drops the sixth predetermined distance, and the second clamping assembly 3 moves backward. At the same time, after the seventh driving mechanism 205 drives the third bracket 204 to move forward the fifth predetermined distance, the suction cup 207 is located above the flexible circuit board. The ninth driving mechanism 209 drives the third connecting arm 206 to move downward the seventh predetermined distance, so that the suction cup 207 sucks away the protective film on the flexible circuit board, and the ninth driving mechanism 209 drives the third connecting arm 206 to move upward the seventh predetermined distance, so as to separate the protective film from the flexible circuit board. In addition, the two metal detection units 208 arranged on the suction cup 207 are used to detect whether the product on the suction cup 207 has a protective film, so as to determine whether the protective film is separated from the flexible circuit board.

[0160] The crimping system provided by the present invention replaces manual work, realizes automatic separation of the protective film from the flexible circuit board, and improves production efficiency.
