Description

Technical Field

[0001] This utility model relates to the field of smartwatch assembly technology, and in particular to a cable bending and shaping device. Background Technology

[0002] One part of the smartwatch assembly process involves bending and reshaping the FPC cable on the U-shaped motherboard. (See...) Figure 1 Before bending the FPC cable 200, the upper part of the FPC cable 200 is tilted outward, which is not conducive to the subsequent bending operation. Therefore, it is necessary to manually push the FPC cable 200 inward first, so that the FPC cable 200 tilts inward (this process is called "cable pre-shaping"). Then, the FPC cable is bent into the required shape (such as bending into an L shape or Z shape, this process is called "cable bending shaping").

[0003] Currently, the bending and shaping operations are mainly completed manually by workers, which results in high labor costs and poor consistency in bending and shaping of FPC cables for different products.

[0004] Therefore, it is necessary to develop a bending and shaping device to complete the bending and shaping of FPC cables, thereby reducing labor costs and improving shaping consistency.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a cable bending and shaping device that can complete the bending and shaping of FPC cables, thereby reducing labor costs and improving shaping consistency.

[0007] To achieve the above objectives, this utility model provides a ribbon cable bending and shaping device for bending and shaping the FPC ribbon cable on a U-shaped watch motherboard, comprising:

[0008] A pre-shaping fixture for ribbon cables, the fixture being used to push the FPC ribbon cables on the U-shaped watch motherboard inwards, the fixture comprising:

[0009] The fixture body is provided with a slot for placing a U-shaped watch motherboard;

[0010] A plurality of push-in components, each of the push-in components being arranged around the periphery of the placement slot, including a sliding seat slidably connected to the main body of the fixture, and a pre-shaping push plate having one end mounted on the sliding seat;

[0011] When the sliding seat is driven, it causes the pre-shaping push plate to slide toward the placement slot, so that the other end of the pre-shaping push plate pushes the FPC cable inward.

[0012] A limiting component is used to extend into the U-shaped watch motherboard to cooperate with the pre-shaping push plate to pre-shape the FPC cable to an inward tilted state;

[0013] A plurality of bending components are arranged around the periphery of the cable pre-shaping fixture and are used to bend and shape the pre-shaped FPC cable.

[0014] Optionally, the other end of the pre-shaping pusher plate is provided with an inclined push surface corresponding to the position of the FPC cable, and the horizontal distance between the inclined push surface and the placement slot gradually increases from top to bottom.

[0015] Optionally, the number of push-in components is three, wherein the push-in component in the center is a center push-in component, and the two push-in components on either side of the center push-in component are side push-in components.

[0016] Each of the sliding seats of the two side push-in assemblies is provided with a push-up spring on the side away from the placement slot. The two push-up springs are used to drive the three push-in assemblies to slide synchronously toward the placement slot.

[0017] Optionally, the bottom of the centered push-in component has an unlocking push plate protruding downwards.

[0018] When the unlocking push plate is driven away from the placement slot, the sliding seat of the central push assembly pushes outward against the sliding seats of the two side push assemblies, causing each of the pre-shaping push plates to move away from the placement slot.

[0019] Optionally, both ends of the sliding seat of the centering push-in component are provided with inclined guide surfaces;

[0020] The distance between the two inclined guide surfaces gradually increases toward the placement slot.

[0021] Optionally, each of the side push-in components is provided with an inclined push portion extending to the outside of the corresponding inclined guide surface.

[0022] Optionally, it may also include an unlocking drive mechanism for driving the unlocking push plate to move away from the placement slot.

[0023] Optionally, the unlocking drive mechanism includes:

[0024] A connecting plate is provided with a push plate slot for inserting the unlocking push plate; wherein the width of the push plate slot is greater than the thickness of the unlocking push plate, so that the unlocking push plate and the push plate slot are connected with a clearance fit.

[0025] Unlock the transverse linear drive mechanism, the drive end of which is connected to the connecting plate, and is used to drive the connecting plate closer to or further away from the placement slot;

[0026] The longitudinal linear drive mechanism is unlocked, and its drive end is connected to the transverse linear drive mechanism for driving the connecting plate to move up and down.

[0027] Optionally, the limiting component includes a pre-shaping limiting baffle disposed opposite to the inclined pushing surface, and a limiting linear drive mechanism that drives the pre-shaping limiting baffle to move up and down.

[0028] Optionally, the bending assembly includes a shaping block located inside the FPC cable and connected to the drive end of the limiting linear drive mechanism, a shaping push block located outside the FPC cable, and a bending linear drive mechanism that drives the shaping push block to move toward the shaping push block to bend the FPC cable.

[0029] The beneficial effects of this utility model are as follows: It provides a cable bending and shaping device. When it is necessary to pre-shape the FPC cable on the U-shaped watch motherboard, first push each of the inner push components outward so that the other end of the pre-shaping push plate moves away from the area directly above the placement slot; then, place the U-shaped watch motherboard into the placement slot (at this time, the FPC cable is tilted outward); then, push each of the inner push components inward so that each of the pre-shaping push plates slides toward the placement slot and pushes the corresponding FPC cable inward. Since the inner side of the FPC cable is provided with a limiting component, the FPC cable cannot tilt inward continuously. Finally, the FPC cable will be clamped by the pre-shaping push plate and the limiting component and maintain a preset inward tilt angle, thereby completing the cable pre-shaping operation.

[0030] Next, the bending component operates to bend and shape the pre-shaped FPC cable, shaping it into a preset shape.

[0031] Therefore, the cable bending and shaping device provided by this utility model can complete the bending and shaping operation of FPC cables, thereby reducing labor costs and improving shaping consistency. Attached Figure Description

[0060] See Figures 2-4 This utility model provides a cable bending and shaping device for bending cables. Figure 1 The FPC cable 200 on the U-shaped watch motherboard 100 shown is bent and shaped, including the cable pre-shaping fixture 300, the limiting component 400, and several bending components 500.

[0061] See Figures 5-7 The pre-shaping fixture 300 is used to push the FPC cable 200 on the U-shaped watch motherboard 100 inward, and includes fixture body 1 and several push-in components.

[0062] The fixture body 1 is provided with a placement slot 101 for placing the U-shaped watch motherboard 100. Each of the inner pushing components is arranged around the periphery of the placement slot 101, including a sliding seat 201 slidably connected to the fixture body 1, and a pre-shaping push plate 202 with one end mounted on the sliding seat 201.

[0063] When the sliding seat 201 is driven, it causes the pre-shaping push plate 202 to slide toward the placement slot 101, so that the other end of the pre-shaping push plate 202 pushes the FPC cable 200 inward.

[0064] The limiting component 400 is used to extend into the U-shaped watch motherboard 100 to cooperate with the pre-shaping push plate 202 to pre-shape the FPC cable 200 to an inwardly inclined state; each of the bending components 500 is arranged around the periphery of the cable pre-shaping fixture 300 and is used to bend and shape the pre-shaped FPC cable 200.

[0065] The cable bending and shaping device provided in this embodiment, when it is necessary to pre-shape the FPC cable 200 on the U-shaped watch motherboard 100, first pushes each of the inner push components outward, so that the other end of the pre-shaping push plate 202 moves away from the area directly above the placement slot 101; then, the U-shaped watch motherboard 100 is placed into the placement slot 101 (at this time, the FPC cable 200 is tilted outward); then, pushes each of the inner push components inward, so that each of the pre-shaping push plates 202 slides toward the placement slot 101 and pushes the corresponding FPC cable 200 inward. Since the inner side of the FPC cable 200 is provided with a limiting component 400, the FPC cable 200 cannot tilt inward continuously. Finally, the FPC cable 200 will be clamped by the pre-shaping push plate 202 and the limiting component 400 and maintain a preset inward tilt angle, thereby completing the cable pre-shaping operation;

[0066] Next, the bending component 500 operates to bend and shape the pre-shaped FPC cable 200, shaping it into a preset shape.

[0067] Therefore, the cable bending and shaping device provided by this utility model can complete the bending and shaping operation of FPC cables 200, thereby reducing labor costs and improving shaping consistency.

[0068] In this embodiment, the other end of the pre-shaping push plate 202 is provided with an inclined push surface 2021 corresponding to the position of the FPC cable 200. The horizontal distance from the inclined push surface 2021 to the placement slot 101 gradually increases from top to bottom. When the push spring 3 drives each of the pre-shaping push plates 202 to push the corresponding FPC cable 200 inward, the inclined push surface 2021 is inclined inward, thus forcing the FPC cable 200 to tilt inward.

[0069] Optionally, the number of push-in components is three, wherein the central push-in component is the central push-in component 2a, and the two push-in components on either side of the central push-in component 2a are the side push-in components 2b.

[0070] Each of the sliding seats 201 of the two side push-in assemblies 2b is provided with a push spring 3 on the side away from the placement slot 101. The two push springs 3 are used to drive the three push-in assemblies to slide synchronously toward the placement slot 101.

[0071] The bottom of the centering push component 2a has an unlocking push plate 2013 protruding downward. When the unlocking push plate 2013 is driven away from the placement slot 101, the sliding seat 201 of the centering push component 2a pushes the sliding seats 201 of the two side push components 2b outward, so that each of the pre-shaping push plates 202 moves away from the placement slot 101.

[0072] Both ends of the sliding seat 201 of the central push-in assembly 2a are provided with inclined guide surfaces 2011; wherein the distance between the two inclined guide surfaces 2011 gradually increases towards the placement slot 101. Correspondingly, each side push-in assembly 2b is provided with an inclined abutment portion 2012 extending to the outside of the corresponding inclined guide surface 2011.

[0073] Release the unlocking push plate 2013, and the push spring 3 drives the side push component 2b to slide towards the placement slot 101. Simultaneously, the inclined push part 2012 pushes the inclined guide surface 2011 inward, thereby causing the central push component 2a to also slide towards the placement slot 101. At this time, the pre-shaping push plates 202 of the three push components can simultaneously push the corresponding FPC cable 200 inward, thereby completing the pre-shaping operation.

[0074] As the unlocking push plate 2013 is pushed outward, the centrally located inner push component 2a slides outward, and the inclined guide surface 2011 pushes the inclined push part 2012 outward, thereby causing the side inner push component 2b to overcome the elastic force of the push spring 3 and slide away from the placement slot 101. At this time, the pre-shaping push plates 202 of the three inner push components can move away from the placement slot 101 simultaneously to carry out loading and unloading operations.

[0075] In this embodiment, the pre-shaping push plate 202 is detachably connected to the corresponding sliding seat 201 by fasteners, so that different pre-shaping push plates 202 can be replaced for different products.

[0076] Optionally, a guide rail slider assembly is provided between the sliding seat 201 and the fixture body 1 to improve sliding smoothness and reduce sliding resistance.

[0077] The cable bending and shaping device further includes an unlocking drive mechanism 600 for driving the unlocking push plate 2013 to move away from the placement slot 101. The unlocking drive mechanism 600 includes a connecting plate 4, an unlocking transverse linear drive mechanism 5, and an unlocking longitudinal linear drive mechanism 6.

[0078] The connecting plate 4 is provided with a push plate slot 401 for the unlocking push plate 2013 to be inserted into; wherein the width of the push plate slot 401 is greater than the thickness of the unlocking push plate 2013, so that the unlocking push plate 2013 and the push plate slot 401 are connected with a clearance fit. The driving end of the unlocking transverse linear drive mechanism 5 is connected to the connecting plate 4, and is used to drive the connecting plate 4 to move closer to or further away from the placement slot 101. The driving end of the unlocking longitudinal linear drive mechanism 6 is connected to the unlocking transverse linear drive mechanism 5, and is used to drive the connecting plate 4 to move up and down.

[0079] When pre-shaping is required, the unlocking horizontal linear drive mechanism 5 drives the connecting plate 4 to move towards the placement slot 101. When the pre-shaping push plate 202 contacts the FPC cable 200, the unlocking horizontal linear drive mechanism 5 stops operating. Since the unlocking push plate 2013 and the push plate slot 401 are connected with a clearance fit, the pre-shaping push plate 202 does not need to rely on the driving force of the unlocking horizontal linear drive mechanism 5 to press the FPC cable 200. Instead, it relies on the elastic force of the push spring 3 to press the FPC cable 200. The clearance fit structure design is to avoid the linear drive mechanism affecting the elastic pressing operation of the push spring 3.

[0080] The limiting component 400 includes a pre-shaping limiting baffle 7 disposed opposite to the inclined push surface 2021, and a limiting linear drive mechanism 8 for driving the pre-shaping limiting baffle 7 to move up and down. The limiting linear drive mechanism 8 is used to drive the pre-shaping limiting baffle 7 to move up and down so that the top corner of the pre-shaping limiting baffle 7 is aligned with the inclined push surface 2021. At this time, the inclined push surface 2021 pushes the FPC cable 200 toward the top corner of the pre-shaping limiting baffle 7, so that the FPC cable 200 tilts inward along the tilt angle of the inclined push surface 2021.

[0081] The bending assembly 500 includes a shaping block 9 located inside the FPC cable 200 and connected to the drive end of the limiting linear drive mechanism 8, a shaping push block 10 located outside the FPC cable 200, and a bending linear drive mechanism 11 that drives the shaping push block 10 to move toward the shaping push block 10 to bend the FPC cable 200.

[0082] The shaping pusher 10 can be set in the required position and at the required angle according to design requirements; this utility model does not limit this.

[0083] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
