Description

Technical Field

[0001] This invention relates to the field of bending equipment technology, and in particular to a bending mechanism and bending pressing equipment. Background Technology

[0002] In recent years, the laptop industry has shown a good growth momentum, and competition in the laptop market has become increasingly globalized. Currently, the demand for laptops is high, and the requirements for the assembly quality of laptops are more stringent. Therefore, achieving rapid assembly of laptops while ensuring quality is an urgent problem to be solved.

[0003] In the assembly process of laptops, many components require bending and assembling ribbon cables onto the frame. Existing automated bending equipment can only perform single bends, and even if it can perform multiple bends, it can only bend the ribbon cable itself, not assemble the ribbon cable onto the frame. To assemble the ribbon cable onto the frame, a production line and multiple bending machines are often required. However, the ribbon cable is usually already connected to the computer screen, making it inconvenient to move between multiple workstations, which can easily lead to low efficiency, slow assembly progress, and low product yield. Summary of the Invention

The bending blocks in the two sets of single-fold modules have different widths, and the bending rollers in the two sets of double-fold modules also have different widths. An extension support portion is provided on one side of the bending roller with the narrower width.

[0067] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0068] Example 1

[0069] Reference Figure 1As shown, this invention discloses a bending mechanism 1 for bending and assembling ribbon cables on a bracket, comprising: a platform module 11, a first-bend module 12, and a second-bend module 13, wherein: the platform module 11 is used to support the ribbon cable and the bracket, as shown in the figure. Figure 2 and Figure 3 As shown, the platform module 11 is provided with a ribbon cable carrier plate 111. The ribbon cable carrier plate 111 has a ribbon cable support channel, which provides space for the ribbon cable and the bracket. Both the ribbon cable and the bracket are sheet-like structures. The ribbon cable and the bracket are placed sequentially on the ribbon cable support channel. The ribbon cable is a strip-shaped structure, which covers the ribbon cable support channel along its extension direction. The bracket is a long strip-shaped structure, which is perpendicular to the extension direction of the ribbon cable support channel along its length. Both ends of the bracket protrude from the ribbon cable support channel. At this time, the bracket is fitted to the ribbon cable and is positioned above the ribbon cable. A bending through hole 112 is opened below the ribbon cable support channel, penetrating the ribbon cable carrier plate 111. The ribbon cable covers the top of the bending through hole 112, and the bracket is positioned on one side of the bending through hole 112.

[0070] Reference Figure 1 and Figure 4 As shown, the bending module 12 is disposed below the platform module 11, and includes: a first bending drive assembly and a bending block 121 connected to the first bending drive assembly. The cross-sectional shape and size of the bending block 121 are the same as the shape and size of the bending through hole 112. The first bending drive assembly drives the bending block 121 to pass through the bending through hole 112. Because the ribbon cable covers the bending through hole 112, when the bending block 121 passes through the bending through hole 112... When the bending block 121 is in motion, it can press and push the ribbon cable to bend once in its direction of movement. After bending, since the ribbon cable is relatively soft and not easy to shape, the bending block 121 is set to press against the ribbon cable continuously so that the ribbon cable always maintains a bent shape. At the same time, a bending surface 1211 is provided at the end of the bending block 121. The bending surface 1211 just fills the bending through hole 112. The bending surface 1211 and the ribbon cable support channel are spliced ​​together to form a continuous bending channel.

[0071] Reference Figure 1 and Figure 6As shown, the two-fold module 13 is disposed on one side of the platform and includes a second bending drive assembly and a bending roller 131 connected to the second bending drive assembly. Because the two-fold module 13 is disposed on the side of the platform, the bending roller 131 is positioned so that it can fall on the ribbon cable carrier plate 111. The second bending drive assembly drives the bending roller 131 to roll along the bending channel. After one bend, the end of the ribbon cable is lifted by the bending block 121. The ribbon cable is distributed in an "L" shape, including a vertical part and a horizontal part. The bracket is placed above the horizontal part of the ribbon cable. At this time, the bending roller 131 passes through the bending channel and can press and push the vertical part of the ribbon cable to bend a second time in its moving direction. The vertical part of the ribbon cable is pushed to bend horizontally by the bending roller 131, thereby enabling the bracket to be assembled into the ribbon cable, realizing the bending assembly of the ribbon cable outside the bracket.

[0072] The bending mechanism 1 of the present invention includes a platform module 11 for arranging and positioning the ribbon cable and the bracket. The platform module 11 and the first bending module 12 cooperate to allow the bending block 121 in the first bending module 12 to act on the ribbon cable, pressing and pushing the ribbon cable to perform the first bend. After the first bend is completed, the first bending module 12 maintains the bending action. The bending block 121 in the first bending module 12 can cooperate with the platform module 11 to form a bending channel for the bending roller 131 of the second bending module 13 to move. The second bending module 13 cooperates with the first bending module 12 so that the bending roller 131 in the second bending module 13 passes through the bending channel, pressing and pushing the ribbon cable to perform the second bend, realizing the multiple bending assembly of the ribbon cable on the bracket. The bending mechanism 1 of the present invention fixes the ribbon cable and the bracket, realizing the bending assembly action of the ribbon cable and the bracket in place, without moving the ribbon cable and the bracket, which can improve assembly efficiency and assembly yield.

[0073] Specifically, during the bending process, since the bending module needs to act directly on the ribbon cable, if the bending module pushes the ribbon cable or bracket to move, the assembly position of the bracket and the ribbon cable will be incorrect compared with the design position. Therefore, in this embodiment, in order to further improve the assembly accuracy, it is also necessary to position the ribbon cable and the bracket on the ribbon cable carrier plate 111.

[0074] Reference Figure 3As shown, in this embodiment, in order to further fix the position of the ribbon cable, a positioning block 113 and a positioning pin 114 are also provided on the ribbon cable carrier plate 111. The positioning block 113 and the positioning pin 114 are respectively provided on both sides of the bending through hole 112. The positioning block 113 is provided on the ribbon cable support channel, and the end of the ribbon cable abuts against the positioning block 113, thereby limiting the bending position of the ribbon cable. The positioning pin 114 is provided on both sides of the ribbon cable support channel, and positioning through holes that cooperate with the positioning pin 114 are opened on both sides of the ribbon cable. The hole-pin cooperation can prevent the ribbon cable from moving during the bending process.

[0075] Specifically, in this embodiment, since both ends of the bracket protrude from the cable support channel, positioning through holes that cooperate with the positioning pins 114 are also provided at both ends of the bracket. After the cable is passed through the positioning pins 114, the bracket is also passed through the positioning pins 114. In this way, the relative position of the cable and the bracket can be fixed by the positioning pins 114, thereby determining the positional relationship of the displacement of the cable and the bracket.

[0076] Specifically, the positioning block 113 has a strip-shaped hole, and the positioning block 113 is locked onto the ribbon cable carrier plate 111 by bolts passing through the strip-shaped hole. The position of the positioning block 113 can be adjusted along the extension direction of the strip-shaped hole, so that different bending positions can be set for different models of ribbon cables.

[0077] Specifically, the positioning pins 114 and 113 can only restrict the position of the ribbon cable and the bracket in the horizontal direction. However, in this embodiment, the bending module 12 is set to press and bend the ribbon cable from below. During this process, the ribbon cable and the bracket may move in the vertical direction along the extension direction of the positioning pin 114, which also affects the bending action of the ribbon cable. There may be a situation where the bending module 12 directly pushes the ribbon cable and the bracket out of the positioning pin 114, which will destroy all subsequent bending actions.

[0078] To prevent the folding module 12 from pushing the ribbon cable out of the positioning pin 114, a vacuum suction hole 119 is also provided on the platform module 11 in this embodiment. The vacuum suction hole 119 provides a vacuum adsorption environment, which can adsorb the ribbon cable onto the platform module 11. On the one hand, it can ensure that the ribbon cable is flat and prevent the ribbon cable itself from wrinkling. On the other hand, the vacuum suction hole 119 can also adsorb and fix the ribbon cable onto the platform module 11, which can prevent the folding module 12 from lifting the ribbon cable as a whole. In this way, even if the folding module 12 is set to press and push the ribbon cable from below, it can only bend the ribbon cable and cannot move the ribbon cable upward.

[0079] To prevent the folding module 12 from pushing the bracket out of the positioning pin 114, this embodiment also provides a cover plate assembly on the platform module 11. The cover plate assembly includes: a cover plate bracket 115, a cover plate 116, a latch 117, and a cover-close detection sensor 118. The cover plate bracket 115 is fixedly mounted on the platform module 11, and is located near the cable carrier plate 111 on one side of the cable carrier plate 111. The end of the cover plate 116 is pivotally connected to the cover plate bracket 115. An external driving force can push the cover plate 116 to rotate around the pivot. During the rotation of the cover plate 116, the cover plate 116 can press against the cable carrier plate 11. On the cover plate 116, a pressing part is provided to press against the bracket. The cover plate 116 is configured to avoid the ribbon cable support channel and can only press against the bracket protruding on both sides of the ribbon cable support channel. When the cover plate 116 is fastened to the ribbon cable carrier plate 111, the pressing part applies force to the bracket from above. In this way, even if a folding module 12 is provided to press and push the ribbon cable from below, the ribbon cable can only be bent and the bracket cannot be moved upward. In addition, in this embodiment, a two-folding module 13 is also provided that needs to pass over the ribbon cable carrier plate 111. In order to provide clearance space for the bending roller 131 in the two-folding module 13, a hollow part is also provided on the cover plate 116 for the bending roller 131 to pass through.

[0080] Specifically, in this embodiment, when the cover plate 116 is fastened to the cable carrier plate 111, a locking buckle 117 is also provided to lock and fix the cover plate 116. The locking buckle 117 is also fixedly installed on the platform module 11. The locking buckle 117 and the cover plate bracket 115 are correspondingly arranged on the other side of the cable carrier plate 111. The locking buckle 117 is a rotatable right-angle block. One side of the locking buckle 117 protrudes from the rotation path of the cover plate 116. When the cover plate 116 moves towards the cable carrier plate 111 by rotating around the pivot, it pushes the locking buckle 117 to rotate. When the cover plate 116 presses against the cable carrier plate 111 by rotating around the pivot, both sides of the locking buckle 117 abut against the cover plate 116, so that the locking buckle 117 is fastened to the cover plate 116.

[0081] Specifically, in this embodiment, in order to detect whether the cover plate 116 is fastened to the ribbon cable carrier plate 111, a cover plate detection sensor 118 is also provided near the latch 117. The cover plate detection sensor 118 is a photoelectric sensor, and a sensing block is provided on the cover plate 116. When the cover plate 116 is fastened to the ribbon cable carrier plate 111, the sensing block blocks the photoelectric sensor, changing the signal of the photoelectric sensor, proving that the cover plate 116 has been fastened in place and subsequent processes can be carried out.

[0082] Specifically, a protruding handle is provided on the cover plate 116, which can be pushed manually or by automated equipment to rotate the cover plate 116.

[0083] Specifically, in this embodiment, a cover plate 116 support platform is also provided on the other side of the cover plate bracket 115. When the cover plate 116 is opened, the cover plate 116 falls on the cover plate 116 support platform.

[0084] Reference Figure 4 As shown, in this embodiment, in order to ensure that the first bending drive assembly can drive the bending block 121 through the bending through hole 112, the following two conditions need to be met: First, the bending block 121 needs to be moved directly below the bending through hole 112; second, a certain pushing force needs to be provided for the bending block 121. Therefore, the first bending drive assembly includes: a mounting plate 122, which can provide installation space below the bending channel; a horizontal slide 123 and a vertical slide 125 are provided on the mounting plate 122, which can adjust their positions in space; the horizontal slide 123 and the vertical slide 125... The components 25 are connected by an adapter plate 124, which has a connecting part and an assembly part. The connecting part is connected to the horizontal slide table 123, and the vertical slide table 125 is disposed on the assembly part. A sliding slider 126 and a slider 126 drive source are disposed on the vertical slide table 125. One end of the slider 126 is connected to the output end of the slider drive source 127, and the other end of the slider 126 is provided with a bending block 121. The slider drive source 127 drives the slider 126, thereby causing the bending block 121 to be inserted into the bending through hole 112.

[0085] Because the ribbon cable is relatively soft, it remains upright after a single bend. If the support portion of the ribbon cable is too short, i.e., the bending block 121 protrudes too low from the ribbon cable carrier plate 111, the length of the ribbon cable protruding from the bending block 121 will be too long, making it prone to tipping over. Therefore, in this embodiment, the bending block 121 is positioned to abut against the ribbon cable at least half its vertical length to adequately support it. Simultaneously, to form a bending channel, the other end of the bending block 121 needs to be aligned as closely as possible with the ribbon cable carrier plate 111 to ensure the bending roller 131 can pass through. To meet these requirements, refer to... Figure 5 As shown, in order to facilitate the bending roller 131 to roll over the bending surface 1211, both ends of the bending surface 1211 are provided with chamfers 1212. Furthermore, the bending surface 1211 is set as an inclined surface. The bottom of the bending surface 1211 is connected to the ribbon cable carrier plate 111, and the top of the bending surface 1211 is pressed against the ribbon cable. The inclined surface ensures that it can connect with the ribbon cable carrier plate 111 while extending the height of the bending block 121 as much as possible so that the bending block 121 can support the ribbon cable as much as possible.

[0086] Reference Figure 6 As shown, the second bending drive assembly includes: a mounting bracket 132, which provides installation space for the second bending drive assembly; a roller drive slide 133 is provided on the mounting bracket 132; the roller drive slide 133 is a lead screw slide, including a drive motor, a lead screw, and a slide base; the drive motor drives the lead screw to rotate, causing the slide base to reciprocate along the extension direction of the lead screw; a connecting plate 134 is provided on the roller drive slide 133, which is driven to reciprocate by the roller drive slide 133; and a support 13 is provided on the connecting plate 134. 5. The support 135 is a fulcrum. A push rod 136 is connected to the support 135 via a rotating shaft. The push rod 136 is equivalent to a lever. A bending roller 131 is provided at one end of the push rod 136, and a push rod drive source 137 is provided at the other end of the push rod 136. When the two-fold module 13 of this embodiment is used to bend the ribbon cable for the second time, the roller drive slide 133 drives the bending roller 131 to pass over the ribbon cable. The push rod drive source 137 provides bending pressure to the bending roller 131 against the ribbon cable.

[0087] Specifically, an elastic connector and a pressure sensor are provided between the push rod drive source 137 and the push rod 136. The elastic connector connects the push rod drive source 137 and the push rod 136 to transmit the thrust between them. The pressure sensor detects the pressure between the push rod drive source 137 and the push rod 136 and controls the pressure applied by the push rod 136 to ensure that the bending roller 131 can press against and bend the cable while preventing excessive pressure from damaging the cable.

[0088] Specifically, in this embodiment, there are two ribbon cables to be bent. Therefore, in order to bend each ribbon cable independently, the bending mechanism 1 includes two sets of mirror-arranged single-fold modules 12 and two sets of mirror-arranged double-fold modules 13. The widths of the bending blocks and bending rollers are set according to the width of the ribbon cables. Since the widths of the two ribbon cables are different, the widths of the bending blocks 121 in the two sets of single-fold modules 12 are set to be different, and the widths of the bending rollers 131 in the two sets of double-fold modules 13 are also set to be different.

[0089] Reference Figure 7 As shown, in this embodiment, since the second bending drive assembly provides pressure applied to the bending roller 131 through a lever structure, in order to ensure that the pressure applied by the two sets of two-fold modules 13 is the same, the pressure detected by the two sets of pressure sensors is set to be the same. However, since the width of the bending roller at the end of the push rod 136 is different, it is easy to cause the applied pressure to deviate for the narrower bending roller. Therefore, in this embodiment, an extension support 1311 is provided on one side of the narrower bending roller 131. The extension support 1311 is equivalent to an extension supplement to the narrower bending roller 131. When the pressure applied by the push rod drive source 137 is the same, it is ensured that the pressure acting on the bending roller 131 is also the same.

[0090] Example 2

[0091] Reference Figure 8 As shown, the present invention also provides a bending and pressing device, including the bending mechanism 1 described in Embodiment 1, and further including: a pressure holding mechanism 2. The pressure holding mechanism 2 is used to hold and fix the bent ribbon cable and bracket. In this embodiment, in order to fix the ribbon cable and bracket together, glue is applied to the bracket before bending with the bending mechanism 1. After bending and assembling the ribbon cable and bracket with the bending mechanism 1, it is necessary to apply moving pressure to make the glue fully between the ribbon cable and the bracket, and to cool and fix the glue. The bending roller 131 in the two-fold module 13 is pressed by the pressure holding component, and the bending roller 131 is pressed to make it elastically deform and press against the ribbon cable, so that the ribbon cable and the bracket can fully contact and combine, and the assembly position of the ribbon cable and the bracket is held and fixed by pressure.

[0092] Reference Figure 9 As shown, the pressure holding mechanism 2 includes: a gantry frame 21, which is disposed above the bending mechanism 1. The gantry frame 21 provides installation space for the pressure holding mechanism 2. A horizontal transfer assembly 22 is disposed on the crossbeam of the gantry frame 21. A lifting assembly 23 is disposed at the execution end of the horizontal transfer assembly 22. A pressure holding assembly 24 is disposed on the lifting assembly 23. The pressure holding assembly 24 is moved in space by the horizontal transfer assembly 22 and the lifting assembly 23, so that the pressure holding assembly 24 can be moved to directly above the bending mechanism 1.

[0093] Reference Figure 10 As shown, the pressure-holding assembly 24 includes: a pressure-holding slide rail 241, a pressure-holding slider 242 disposed on the pressure-holding slide rail 241, buffer blocks 243 and pressure-holding heads 244 disposed at both ends of the pressure-holding slider 242 along the sliding direction of the pressure-holding slider 242, a buffer spring 245 and a pressure-holding sensor 246 disposed between the buffer blocks 243 and the pressure-holding slider 242, and slider limiting pins 247 disposed on both sides of the pressure-holding slider 242; the lifting assembly 23 drives the entire pressure-holding assembly 24 to move downward, so that the pressure-holding head 244 presses against the bending roller 131, the sliding direction of the pressure-holding slider 242 is restricted by the slider limiting pins 247, the pressure-holding slider 242 elastically abuts against the buffer blocks 243 by the buffer spring 245, and the pressure sensor 246 detects the pressure applied to the bending roller 131 by the pressure-holding head 244 to meet the preset pressure-holding conditions.

[0094] Specifically, due to assembly errors, the position of the pressure holding head 244 relative to the bending roller 131 may have a slight deviation. In order for the pressure holding head 244 to accurately press against the bending roller 131, the pressure holding head 244 is movably connected to the pressure holding slider 242 via a rotating pin 248 and a floating block 249 sleeved on the rotating pin 248. Even if there is a deviation in the relative position between the pressure holding head 244 and the bending roller 131, automatic alignment can be achieved by the floating pressure holding head 244. Furthermore, the end of the pressure holding head 244 is provided with an arc-shaped pressure holding groove 2441 that cooperates with the bending roller 131, which facilitates the docking of the pressure holding head 244 with the bending roller 131.

[0095] Specifically, a bending roller 131 is used to press the ribbon cable and the bracket together. Since the bending roller 131 has a cylindrical structure, the contact surface between the bending roller 131 and the ribbon cable is only a straight line. However, the surface between the bracket and the ribbon cable base is a sheet structure. In order to increase the contact area between the bending roller 131 and the ribbon cable, in this embodiment, the bending roller 131 is made of an elastic material. The bending roller 131 can elastically deform. After the bending roller 131 contacts the ribbon cable, the bending roller 131 deforms under force, changing the line contact with the ribbon cable into a surface contact, thereby expanding the area of ​​pressure applied to the ribbon cable and enabling the bracket and the ribbon cable to be fully pressed together.

[0096] To ensure the bending quality meets requirements, the ends of the cable must be flush after bending. Therefore, refer to... Figure 8 and Figure 11 As shown, in this embodiment, a detection mechanism 3 is also provided. The detection mechanism 3 is disposed on the horizontal transfer assembly 22. The detection mechanism 3 is used to perform visual inspection on the bent and pressure-held ribbon cable and bracket. Specifically, the detection mechanism 3 includes: a camera mounting bracket 31, a detection camera 32, a detection light source 33, and a light source mounting bracket 34.

[0097] Specifically, the ribbon cable is generally already connected to an electronic device. For example, in this embodiment, one end of the ribbon cable is already connected to a display device. Only after the position of the display device is accurately fixed can the accuracy of the relative position of the ribbon cable be guaranteed. Therefore, referring to... Figure 8 and Figure 12 As shown, in this embodiment, a positioning mechanism 4 is also provided. The positioning mechanism 4 is used to support and position the device connected to the ribbon cable. Specifically, the positioning mechanism 4 includes: a device carrier plate 41, which is used to carry the electronic device. In order to fix the device on the device carrier plate 41, two fixing methods are adopted in this embodiment: one is to provide a suction cup 42 on the device carrier plate 41 to adsorb the device; the other is to provide a positioning block on the device carrier plate 41 and a secondary clamping device 45 corresponding to the positioning block, so that the device can be clamped and fixed by the cooperation of the secondary clamping device 45 and the positioning block.

[0098] Specifically, depending on the actual application scenario, the equipment has various different models, and the sizes of different models are also different. In order to enable the positioning mechanism 4 of this embodiment to clamp and position different models of equipment, the positioning blocks are provided, including: a first positioning block 43 and a second positioning block 44. The first positioning block 43 is fixedly set on the equipment carrier plate 41, and multiple first positioning blocks 43 together form a first equipment accommodating space on the equipment carrier plate 41. The second positioning block 44 is driven by a cylinder to lift and lower on the equipment carrier plate 41, and can protrude from the equipment carrier plate 41 or retract into the equipment carrier plate 41. Multiple second positioning blocks 44 together form a second equipment accommodating space on the equipment carrier plate 41. Controlling the lifting and lowering of the second positioning block 44 can form different accommodating spaces, thereby realizing the fixing of different models of equipment. The secondary clamping device 45 is set at the corner of the equipment carrier plate 41 and cooperates with the first positioning block 43 or the first positioning block 43 to clamp the equipment.

[0099] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
