Description
Technical Field
[0001] This utility model relates to the field of notebook riveting equipment, and in particular to a notebook frame positioning mechanism and an automatic riveting device having the same. Background Technology
[0002] In the production of laptops, there are generally two parts: the laptop frame and the display shell. The display shell is pivotally mounted to the laptop frame, and the two are mainly connected by a hinge axis (i.e., a pivot column).
[0003] The existing shafts mainly include two types:
[0004] 1. The advantage of CNC-machined pivots on the main unit casing is their superior integration, but the corresponding production cost is high, and the CNC machining time for pivots is long, resulting in slower efficiency. This hinge riveting method uses a tight interference fit between the hole and the pivot. However, current production methods have significant limitations. For example, the coaxiality requirements between the pivot and the pivot hole in the laptop casing are very high, typically within 0.05mm. The distance the pivot is pressed into the laptop casing is also crucial, requiring very high precision control, with tolerances typically within ±0.05mm. Furthermore, controlling the pressing force is also very important, making the manufacturing process quite difficult.
[0005] 2. A common method for connecting the laptop's display casing to the main body is using screws for double-sided fastening. This method is easy to manufacture and has a low cost, but the size is relatively large, which is not conducive to optimizing the laptop's structure. The hinge has many connection points, resulting in lower precision and impacting its lifespan. Another method involves riveting the hinge posts, but current production methods have significant limitations. The spacing during hinge loading and riveting is greatly affected (the distance between the hinge hole and the hinge post in the laptop frame is small, for example, 3mm ± 0.5mm). Therefore, high precision control is required (excessive or insufficient pressure, or excessive or insufficient precision control, can easily damage the riveting holes), resulting in a higher defect rate.
[0006] One factor is that because the processing spacing of the laptop frame is small, the positioning requirements are also high. Therefore, how to achieve the positioning of the laptop frame is also a key factor. Summary of the Invention
[0007] The main objective of this invention is to provide a positioning mechanism for a notebook frame and an automatic riveting device having the same, in order to solve the aforementioned problems.
[0008] To achieve the above objectives, this utility model proposes a positioning mechanism for a notebook frame, comprising:
[0009] A rack, wherein the rack is provided with a base for placing a laptop frame, and the front end of the base is provided with a baffle;
[0010] A pusher seat is disposed opposite to a baffle plate and is connected to a first driving device. The first driving device is used to drive the pusher seat to move between a position close to or far from the baffle plate.
[0011] The abutment is located on the upper wall of the base. Two sets of abutments are provided, positioned on both sides of the inner wall of the base. The abutments are also located on both sides of the pusher.
[0012] The bottom wall of the base is provided with a second driving mechanism that drives the two abutments to move toward positions that are far apart or close together.
[0013] In the actual design, the laptop frame is placed downwards. Therefore, the front frame of the laptop frame is located on the outer wall of the rivet hole and fits against the baffle, thereby achieving the positioning of the outer wall of the rivet hole. At the same time, when the two abutments move away from each other, they abut against the inner side of the laptop frame located in the shaft hole. Therefore, when the riveting device is working, the pressure head abuts against the abutment, thereby riveting the shaft into the rivet hole (that is, it achieves the limitation of the outer peripheral wall and outer side wall of the rivet hole, thereby achieving precise positioning of the smaller machining position and ensuring the balance of force). Its structure is simple and stable, while ensuring the stable positioning of the laptop frame and avoiding the problem of the existing laptop frame being affected by the small spacing, which affects the riveting stability.
[0014] An automatic riveting device for laptop frames includes,
[0015] The aforementioned positioning mechanism for the notebook frame;
[0016] The feeding and riveting device has two sets located on both sides of the notebook frame positioning mechanism. The feeding and riveting device has a fixture and a pressure head. The fixture is used to place the rivet post, and the pressure head is used to rivet the rivet post into the rivet hole.
[0017] A visual inspection device is provided, comprising two sets, which are located between the notebook frame positioning mechanism and the feeding and riveting device. The visual inspection device is used to detect the axis of the rivet post and the axis of the rivet hole.
[0018] In practical design, the relative positions of the rivet post and rivet hole can be accurately obtained through the setting of a vision inspection device, thereby reducing riveting errors, improving riveting stability, and improving riveting accuracy. The feeding riveting device is equipped with an adjustment platform, which can be adjusted according to the error between the two to improve alignment. At the same time, the adjustment platform can be adapted to different products to improve the applicability of the equipment. Attached Figure Description

[0045] like Figures 1 to 10 As shown, a positioning mechanism for a notebook frame includes,
[0046] The rack has a base 9 for placing a laptop frame, and a baffle 91 is provided at the front end of the base 9.
[0047] Push seat 92, which is disposed opposite to baffle 91, and is connected to first driving device 92c. The first driving device is used to drive push seat 92 to move between a position close to or far from baffle 91.
[0048] Abutment 93 is provided on the upper wall of base 9. Two sets of abutment 93 are provided on both sides of the inner wall of base 9. Abutment 93 is also provided on both sides of push base 92.
[0049] The bottom wall of the base 9 is provided with a second drive mechanism 93d that drives the two abutments 93 to positions that are far apart or close together.
[0050] In the actual design, the laptop frame is placed downwards. Therefore, the front frame of the laptop frame is located on the outer wall of the rivet hole and fits against the baffle 91, thereby achieving the positioning of the outer wall of the rivet hole. At the same time, when the two abutments 93 move to a position away from each other, they abut against the inner side of the laptop frame located in the shaft hole. Therefore, when the riveting device is working, the pressure head abuts against the abutment 93, thereby riveting the shaft into the rivet hole (that is, the outer peripheral wall and outer side wall of the rivet hole are limited, thereby achieving precise positioning of the smaller machining position and ensuring the balance of force). Its structure is simple and stable, while ensuring the stable positioning of the laptop frame and avoiding the problem of the existing laptop frame being affected by the small spacing, which affects the riveting stability.
[0051] Specifically, the push base 92 has support arms 92a on both sides, and the front end of the support arm 92a has a groove 92b.

The pressing seat 93 extends towards the shaft hole after passing through the through hole 93a. By setting the through hole 93a, multi-position positioning of the rivet hole can be achieved in a small area, thereby ensuring the stability of the processing.
[0053] Specifically, the second driving mechanism 93d is connected to a driving block 93e. The driving block 93e has first inclined surfaces 93f on both sides, and the lower end of the abutment 93 has a second inclined surface 93g that cooperates with the first inclined surfaces 93f. The abutment 93 is equipped with a top spring to keep it away from the rivet holes. The first inclined surfaces 93f and the second inclined surfaces 93g can drive the abutment 93 to cooperate with both rivet holes simultaneously, thereby achieving the positioning of the notebook frame.
[0054] Specifically, the first driving device 92c and the second driving mechanism 93d are telescopic motors, telescopic cylinders, or linear lead screw pairs.

The feeding riveting device is equipped with an adjustment platform, which can be adjusted according to the error between the two to improve alignment. At the same time, the adjustment platform can be adapted to different products to improve the applicability of the equipment.

[0066] In the actual design, the hinge is placed on the fixture 3, and then the position of the shaft 100 is adjusted (e.g., in the X, Y, and Z directions, with the width direction as the X-axis) by adjusting the platform 7 according to the relative position between the rivet hole and the shaft 100, thereby ensuring the riveting accuracy.
[0067] During processing, the load-bearing transmission device 43 drives the load-bearing slider 42 to move, and the pressure head 61 abuts against the rear end of the adjusting fixture 3, driving the first base 21 to move until the shaft 100 extends into the riveting hole. The pressure head 61 applies a predetermined pressure to the shaft 100, thereby realizing the installation of the hinge. The first drive device 4 and the auxiliary drive device are used to realize the movement of a large stroke, and the adjustment platform 7 is used to adjust the small stroke of the shaft 100, thereby ensuring the accuracy and stability of riveting and improving the processing qualification rate.
[0068] Specifically, the adjustment platform 7 includes a Z-axis precision moving platform 71, an X-axis precision moving platform 72, and / or a Y-axis precision moving platform 72, all mounted on the first base 21. In a preferred embodiment, precise adjustment is possible in the X, Y, and Z directions, thereby enabling adaptability to different products and achieving processing versatility.

[0072] The copying seat 31 is provided with a copying groove 31a, and the clamp 32 is provided with a copying surface 31b that cooperates with the copying groove. The first telescopic motor 33 is used to drive the copying surface to move between a position close to the copying groove and a position far away from the copying groove, thereby achieving stable clamping of the hinge and causing the shaft 100 to extend out between the copying seat 31 and the clamp 32.
[0073] Specifically, the pressure head 61 abuts against the side wall of the profile seat 31, and the pressure head 61 is gradually reduced in diameter from back to front, thereby concentrating the force on a localized area and improving the stability of the force.
[0074] Specifically, the second positioning plate 52 is provided with a rotating device, which is connected to the pressure head 61 and can drive it to rotate, thereby realizing its spin-pressing function.

The pressure sensor 63 can be used independently or integrated into the rotating device. The above description is merely a preferred embodiment of this utility model and does not limit the patent scope of this utility model.
