[0047] Reference Figures 1 to 4 One embodiment of the present application provides a folding device, which has a folded state and an open state. The folding device includes a fixed seat 10, a flip member 20, a driving mechanism 30, and a lifting mechanism 40. The fixed seat 10 has a first bearing area 101, and the first bearing area 101 is provided with a receiving through hole 11. The flip member 20 has a second bearing area 201 spliced with the first bearing area 101. The first bearing area 101 and the second bearing area 201 are used to support different parts of the workpiece 200 ( Figure 1 The drawings of the workpiece 200 in the natural state and the bent state are shown in FIG. Figure 6 As shown, the bending state of the workpiece 200 is as shown in FIG. Figure 7 As shown, the workpiece 200 may, for example, comprise a circuit board. It is understood that the workpiece may also be other bendable objects. In the open position, the flip member 20 is positioned to one side of the fixed base 10. In the flexed position, the flip member 20 can be flipped relative to the fixed base 10, such that the first support area 101 and the second support area 201 are arranged at an angle or overlap. The flip member 20 and the fixed base 10 are positioned relative to each other to jointly compress the bent workpiece 200. The flip member 20 and the fixed base 10 may be rotatably connected or disconnected.

[0048] In the open state, as viewed along the placement direction of the flip member 20 and the fixing base 10, the driving mechanism 30 is connected to the side end of the flip member 20. The lifting mechanism 40 is reciprocatingly extendable. In the folded state, the lifting mechanism 40 is used to move within the accommodating through-hole 11 toward the flip member 20 to abut the workpiece 200, thereby applying additional abutting force to the bent and bonded workpiece 200, thereby preventing the bent workpiece 200 from bouncing off before the adhesive is fully set.

[0049] During specific use, the folding device is first in the open state, and the workpiece 200 in its natural state is placed between the first supporting area 101 and the second supporting area 201. The driving mechanism 30 then operates to cause the flip member 20 to flip, causing the folding device to transition from the open state to the folded state. At this time, the workpiece 200 transitions from its natural state to the folded state, and the adhesive provided on the workpiece 200 adheres to the bent workpiece. The lifting mechanism 40 then extends upward to apply a resisting force, thereby increasing the opposing resisting force on the bent workpiece 200 to offset the damage to the adhesive caused by the elastic force generated by the workpiece 200. This can solve the problem of the bent workpiece 200 bouncing or peeling off after bonding, and helps to improve the bonding stability of the bent workpiece 200.

[0050] In the present application, the driving mechanism 30 is connected to the flip member 20 by transmission, so that the flip member 20 can flip relative to the fixed seat 10, thereby driving the workpiece placed on the flip member 20 and the fixed seat 10 to bend, so that the adhesive provided on the workpiece 200 can adhere to the bent workpiece 200. In addition, the folding device of the present application is additionally provided with a lifting mechanism 40, and a receiving hole 11 is provided in the bearing area of the fixed seat 10, so that the lifting mechanism 40 can move telescopically within the receiving hole 11, thereby being able to apply additional resistance force to the folded workpiece 200, so that the folding device of the present application can solve the problem of the workpiece 200 bouncing off after being bent and bonded, thereby helping to improve the bonding stability of the bent workpiece 200.

[0051] In some embodiments, reference Figure 4 and Figure 5 The lifting mechanism 40 includes a first driving member 41, a connecting seat 42 and a lifting assembly 43. The first driving member 41 is used to provide a reciprocating driving force. Exemplarily, the first driving member 41 can be a motor, a cylinder or a hydraulic cylinder. The connecting seat 42 is connected to the output shaft of the first driving member 41, so that the first driving member 41 can drive the connecting seat 42 to move back and forth. Exemplarily, the connecting seat 42 can be installed by connecting nails or fixing the shaft. The connecting seat 42 is provided on the fixing seat 10 away from the first bearing area 101 (refer to Figure 1) side. The upper top assembly 43 includes a connecting pin 431, an upper top piece 432 and a reset piece 433. The connecting pin 431 can movably pass through the connecting seat 42 relative to the first bearing area 101. One end of the connecting pin 431 is used to limit and abut against the connecting seat 42. The upper top piece 432 is arranged in the accommodating through hole 11 and is connected to the other end opposite to the connecting pin 431. Exemplarily, the upper top piece 432 can be provided with a connecting hole, and the connecting pin 431 can be arranged in the connecting hole to achieve the connection between the two. Exemplarily, the upper top piece 432 can abut against the hole wall of the accommodating through hole 11. The reset piece 433 is arranged circumferentially around the connecting pin 431. One end of the reset piece 433 abuts against the end face of the upper top piece 432 facing away from the first bearing area 101, and the other end of the reset piece 433 abuts against the connecting seat 42. Exemplarily, the reset piece 433 can be a reset spring or an elastic sleeve. During operation, the first driving member 41 pushes the connecting seat 42 upward, compressing the reset member 433. When the first driving member 41 is in the extended state, at least part of the deformation of the reset member 433 is restored, driving the connecting pin 431 and the upper push member 432 to move upward relative to the connecting seat 42, thereby applying additional supporting force to the workpiece 200. The structure of the upper push mechanism 40 facilitates the adjustment of the supporting force as needed, thereby improving the adaptability of the folding device.

[0052] In another embodiment, the lifting mechanism 40 may only include the first driving member 41 and the connecting seat 42 , and the connecting seat 42 may be disposed in the accommodating through hole 11 .

[0053] In some embodiments, the number of the first carrying area 101 and the second carrying area 201 is the same and both are at least two (see Figure 1 and Figure 2 ), in the figure, the number of both the first bearing areas 101 and the second bearing areas 201 are six. The number of upper components 43 is the same as the number of the first bearing areas 101, and the number of the first driving member 41 and the connecting seat 42 are both one. Each upper component 432 is arranged in a receiving hole 11 of a first bearing area 101. For example, the number of receiving holes 11 can be the same as the number of upper components 43. Observing from the end of the flip member 20 connected to the driving mechanism 30, at least two first bearing areas 101 are arranged in a row, and at least two second bearing areas 201 are arranged in a row. Increasing the number of the first bearing areas 101 and the second bearing areas 201 and coordinating with the structure of the upper mechanism 40 is beneficial to improving the bending efficiency while also ensuring that each workpiece 200 is subjected to uniform force.

[0054] In some embodiments, reference Figure 3 and Figure 4The flexing device further includes a guide structure 50, which is disposed beside the connecting seat 42 and oriented along the driving direction of the first driving member 41. The connecting seat 42 is slidably connected to the guide structure 50. In this embodiment, the guide structure 50 may be a guide rail. Accordingly, a guide groove may be provided in the connecting seat 42, and the guide rail may be disposed within the guide groove. In another embodiment, the guide structure 50 may be provided with a guide groove or a guide hole, and the connecting seat 42 may be disposed within the guide groove or the guide hole. The provision of the guide structure 50 helps to improve the directional stability of the connecting seat 42.

[0055] In this embodiment, there are two guide structures 50, which further improves directional stability. The end surface of the connecting base 42 facing away from the fixing base 10 is recessed to form a mounting groove 421. The first driving member 41 is disposed within the mounting groove 421. The edge of the side wall of the mounting groove 421 is slidably connected to the guide structure 50, thereby further reducing the integrated volume of the lifting mechanism 40.

[0056] In some embodiments, reference Figure 1 The end of the flip member 20, which is transmission-connected to the drive mechanism 30, protrudes beyond the adjacent end of the fixed base 10. When in the open position, the flip member 20 and the fixed base 10 together form a clearance space. The protruding configuration of the flip member 20 reduces spatial interference with the fixed base 10, thereby increasing the installation flexibility of the drive mechanism 30 and facilitating its installation.

[0057] In some embodiments, the flexing device further includes a limit seat 60, which is disposed within the avoidance space and is flush with the end surface of the fixing base 10 having the first bearing area 101. The limit seat 60 is used to limit the degree of flipping of the flip member 20. The provision of the limit seat 60 helps prevent the flip member 20 from over-flipping.

[0058] In some embodiments, the flexing device further includes a first bearing seat 70, which is disposed on the side of the flip member 20. The driving mechanism 30 includes a first rotating shaft 31, a first transmission wheel 32, a second driving member 33, and a second transmission wheel 34. The first rotating shaft 31 is rotatably connected to the first bearing seat 70, one end of the first rotating shaft 31 is connected to the flip member 20, and the other opposite end of the first rotating shaft 31 passes through the first bearing seat 70. Exemplarily, the first rotating shaft 31 can be mounted on the protruding end of the flip member 20 by screw fixing, and the first rotating shaft 31 can be mounted on the end surface of the flip member 20 having the second bearing area 201. The first transmission wheel 32 is mounted on the end of the first rotating shaft 31 away from the flip member 20. The output shaft of the second driving member 33 is arranged perpendicular to the first rotating shaft 31. Exemplarily, the second driving member 33 can be a rotary motor. The second transmission wheel 34 is mounted on the output shaft of the second driving member 33. The second transmission wheel 34 engages with the first transmission wheel 32, so that rotation of the second transmission wheel 34 drives the first transmission wheel 32 to rotate synchronously. For example, both the first transmission wheel 32 and the second transmission wheel 34 may be gears. The second driving member 33 is used to drive the second transmission wheel 34 to rotate. The combination of the driving member and the transmission wheel drives the flip member 20, thereby improving flipping stability.

[0059] In some embodiments, the flexing device further includes a second bearing seat 80 and a second rotating shaft 81. The second bearing seat 80 is disposed on the other side of the flip member 20, away from the first bearing seat 70. One end of the second rotating shaft 81 is fixed to the flip member 20, and the other end of the second rotating shaft 81 is rotatably connected to the second bearing seat 80. For example, the other end of the second rotating shaft 81 is rotatably mounted within the second bearing seat 80. The first rotating shaft 31 and the second rotating shaft 81 have the same rotational direction. The coordination of the second bearing seat 80, the second rotating shaft 81, the first bearing seat 70, and the drive mechanism 30 further improves flipping stability.

[0060] In another embodiment, only the second driving member 33 may be used to drive the flipping member 20 to flip.

[0061] In some embodiments, reference Figure 1 and Figure 2 Observing the end of the flip member 20 connected to the drive mechanism 30, positioning posts 21 are provided on opposite sides of the first bearing area 101 and the second bearing area 201. Both the fixed base 10 and the flip member 20 are provided with clearance holes 22. In the folded state, each positioning post 21 is positioned within a clearance hole 22. The positioning posts 21 are used to limit contact with the workpiece 200, thereby improving the positioning accuracy of the folding device and eliminating the need for manual workpiece positioning. Furthermore, the use of positioning posts 21 for limiting position also facilitates workpiece removal.

[0062] When the positioning structure is not provided, manual limiting can be used to prevent the workpiece 200 from moving during the bending process.

[0063] In some embodiments, reference Figure 4 The folding device also includes a heating mechanism 93, which is used to heat the workpiece 200. The heating mechanism 93 is fixed to at least one of the end surface of the fixing seat 10 facing away from the first bearing area 101 and the end surface of the flip member 20 facing away from the second bearing area 201. For example, the heat-curing adhesive can be heated and cured by the heating mechanism 93, or when the temperature is too low to destroy the bonding strength of the adhesive, the heating mechanism 93 can also be used to heat and ensure the bonding strength. The folding device is equipped with a heating mechanism 93 to improve adaptability. For example, the heating mechanism 93 can include a heating tube and a heating plate, and the heating mechanism 93 can be heated by energizing.

[0064] In some embodiments, reference Figure 1 、 Figure 3 and Figure 4 The flexing device further includes a mounting frame 90, which includes a first mounting portion 91 and a second mounting portion 92. The second mounting portion 92 is disposed within the mounting frame 90 and connected to the bottom end of the first mounting portion 91. The fixing seat 10, the driving mechanism 30, the limiting seat 60, the first bearing seat 70, and the second bearing seat 80 are all connected to the top end of the first mounting portion 91. The first driving member 41 and the guide structure 50 are both connected to the second mounting portion 92. The connecting seat 42 is disposed through the first mounting portion 91.

[0065] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
