Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment, and in particular relates to a welding component and a strip splicing device. Background Technology

[0002] Plastic steel strapping (also known as packaging strapping or bundling strapping) is a key material for transporting and securing solar cell modules. It is necessary to firmly connect the end of the plastic steel strapping from the exhausted roll to the beginning of the new roll. How to improve the splicing quality of plastic steel strapping is a technical problem that needs to be solved. Utility Model Content

[0003] The main purpose of this utility model is to provide a welding assembly and strip splicing device to improve the welding quality of two strip sections.

[0004] This utility model achieves the above objectives through the following technical solution:

[0005] A welding assembly includes a vertical plate, a pressurizing cylinder, an upper friction head, two connecting rods, a drive arm, and a friction head drive mechanism. The cylinder body of the pressurizing cylinder is connected to the upper part of the vertical plate, and the piston rod of the pressurizing cylinder is connected to a sleeve.

[0006] The top of the upper friction head is connected to the sleeve, and the friction surface of the upper friction head is perpendicular to the piston rod axis of the pressurized cylinder;

[0007] The upper ends of the two connecting rods are hinged to the sleeve, and the lower ends are hinged to the side of the upper friction head. The axial direction of the connecting rod hinge axis is parallel to the friction surface of the upper friction head.

[0008] One end of the drive arm is hinged to the upper friction head, and the hinge axis of the drive arm is aligned with the hinge axis of the connecting rod. The friction head drive mechanism is connected to the other end of the drive arm, and the friction head drive mechanism drives the upper friction head to reciprocate.

[0009] Specifically, the top of the upper friction head is elastically engaged with the piston rod of the pressurized cylinder, and the upper friction head elastically floats along the axial direction of the piston rod.

[0010] Specifically, the welding assembly also includes a limiting block, an upper pin, and a lower pin. The limiting block is fixed to the vertical plate and is located between the piston rod of the pressurized cylinder and the upper friction head. The limiting block has a vertical hole for the sleeve to be accommodated, and waist holes are opened on both sides of the limiting block, which are connected to the vertical hole.

[0011] The upper pin passes through the waist hole, connecting the upper end of the hinged connecting rod and the sleeve. The waist hole of the limiting block restricts the upper pin to move along the length of the waist hole. The lower pin passes through the lower end of the waist hole, the upper friction head, and the drive arm. The axial directions of the lower pin and the upper pin are parallel to the friction surface of the upper friction head.

[0012] Specifically, the outer diameter of the sleeve matches the inner diameter of the vertical hole, allowing the sleeve to move along the length of the vertical hole. During the high-frequency vibration of the upper friction head, the limiting block restricts the radial position of the sleeve, which not only improves the stability of the entire welding assembly but also prevents the pressure cylinder from being subjected to bending moment during the operation of the upper friction head driven by the drive arm, thus extending the service life of the pressure cylinder.

[0013] Specifically, the welding assembly also includes a movable plate and a lower friction head, with a conveying channel provided on the movable plate and located below the upper friction head;

[0014] The lower friction head is located at the bottom of the conveying channel, and the friction surface of the lower friction head is arranged opposite to that of the upper friction head.

[0015] The friction head drive mechanism includes a gearbox and a welding motor. The gearbox is fixed to the moving plate and includes a power input end and a power output end. The power output end is connected to the drive arm.

[0016] The welding motor shaft is connected to the power input end of the gearbox, and the welding motor drives the upper friction head to vibrate through the gearbox and drive arm.

[0017] Specifically, the conveying channel includes a conveying trough, the conveying trough cover is provided with an upper cover, and the welding assembly also includes a limiting member, which is disposed on the upper cover and located on one or both sides of the upper friction head. The limiting member limits the conveying width of the conveying channel.

[0018] Specifically, the limiting component includes limiting plates and limiting posts. One end of the two limiting plates is hinged to the conveying channel, and the upper end of the two limiting posts is fixed to the other end of the limiting plates. The limiting posts are located inside the conveying channel, and the two limiting posts can be adjusted along the width direction of the conveying channel.

[0019] This utility model also provides a strip splicing device, including the aforementioned welding components.

[0020] Compared with the prior art, the present invention has the following technical effects:

[0021] By setting two connecting rods with their ends hinged to the sleeve and the upper friction head respectively, the upper friction head can be reciprocated stably. In addition, the pressure cylinder applies pressure to the upper friction head. The pressure cylinder applies pressure in two working processes: first, during the friction welding process of the upper friction head, and second, after the upper friction head is welded, the pressure is maintained, thereby improving the welding quality of the welded components.

[0031] The following is combined with Figures 1 to 9 This utility model will now be described.

[0032] like Figures 1 to 7 As shown, the welding assembly 40 includes a vertical plate 41, a pressurizing cylinder 42, an upper friction head 43, two connecting rods 44, a drive arm 45, and a friction head drive mechanism. The cylinder body of the pressurizing cylinder 42 is connected to the upper part of the vertical plate 41, and the piston rod of the pressurizing cylinder 42 is connected to the sleeve 421.

[0033] The top of the upper friction head 43 is connected to the sleeve 421, and the friction surface of the upper friction head 43 is perpendicular to the piston rod axis of the pressurized cylinder 42.

[0034] The upper ends of the two connecting rods 44 are hinged to the sleeve 421, and the lower ends are hinged to the side of the upper friction head 43. The axial direction of the hinge axis of the connecting rod 44 is parallel to the friction surface of the upper friction head 43.

[0035] One end of the drive arm 45 is hinged to the upper friction head 43, and the hinge axis of the drive arm 45 is aligned with the hinge axis of the connecting rod 44; the friction head drive mechanism is connected to the other end of the drive arm 45, and the friction head drive mechanism drives the upper friction head 43 to reciprocate.

[0036] By setting two connecting rods 44 with their ends hinged to the sleeve 421 and the upper friction head 43 respectively, the upper friction head 43 can reciprocate stably. In addition, the pressure cylinder 42 applies pressure to the upper friction head 43. The pressure cylinder 42 applies pressure in two working processes: first, during the friction welding process of the upper friction head 43, and second, after the upper friction head 43 finishes welding, the pressure is maintained, thereby improving the welding quality of the welding assembly 40.

[0037] The top of the upper friction head 43 is elastically engaged with the piston rod of the pressurized cylinder 42, and the upper friction head 43 elastically floats along the axial direction of the piston rod.

[0038] By setting the upper friction head 43 to the piston rod of the pressurized cylinder 42 in an elastic connection, it is possible not only to adapt to the fluctuation of strip thickness, but also to ensure stable welding pressure.

[0039] like Figure 2 As shown, the welding assembly 40 also includes a bushing 422 and a compression spring 423. The upper end of the bushing 422 is sleeved on the outer periphery of the sleeve 421. The bushing 422 and the sleeve 421 form an axial movement and radial limiting fit. The bottom end of the bushing 422 and the ball groove of the upper friction head 43 are balls (not shown in the figure). The compression spring 423 is located between the bushing 422 and the sleeve 421. One end of the compression spring 423 is pressed on the sleeve 421 and the other end is pressed on the bushing 422.

[0040] During the friction welding process of the upper friction head 43, the drive arm 45 drives the upper friction head 43 to reciprocate along the X direction. The top of the upper friction head 43 has a ball groove, and the length direction of the ball groove is consistent with the movement direction of the drive arm 45. The ball groove at the top of the upper friction head 43 and the bottom of the bushing 422 are balls. The movement direction of the bushing 422 is only the length direction of the piston rod of the pressurizing cylinder 42. The pressurizing cylinder 42 transmits pressure through the bushing 422 and the balls.

[0041] Pressure is transmitted through the connecting rods 44 on both sides of the upper friction head 43 and the balls under the bushing 422, which prevents the upper friction head 43 from rotating too much around the lower hinge axis, ensuring that the pressure of the upper friction head 43 can be evenly distributed and improving the welding quality.

[0042] During the downward pressing of the upper friction head 43, the compression spring 423 between the bushing 422 and the sleeve 421 can provide buffering to prevent the upper friction head 43 from hard impacting and damaging the strip or the lower friction head 22.

[0043] The welding assembly 40 also includes a limiting block 46, an upper pin 47 and a lower pin 48. The limiting block 46 is fixed to the vertical plate 41. The limiting block 46 is located between the piston rod of the pressurizing cylinder 42 and the upper friction head 43. The limiting block 46 has a vertical hole 461 for the sleeve 421 to be accommodated. Waist holes 462 are opened on both sides of the limiting block 46, and the waist holes 462 are connected to the vertical hole 461.

[0044] The upper pin 47 passes through the waist hole 462 and hinges the upper end of the connecting rod 44 to the sleeve 421. The waist hole 462 of the limiting block 46 limits the movement of the upper pin 47 along the length of the waist hole 462. The lower pin 48 passes through the waist hole 462 and hinges the lower end of the connecting rod 44, the upper friction head 43 and the drive arm 45. The axial directions of the lower pin 48 and the upper pin 47 are parallel to the friction surface of the upper friction head 43.

[0045] By setting a limiting block 46 to fix the vertical plate 41, and a vertical hole 461 starting in the middle of the limiting block 46, on the one hand, it serves to guide the sleeve 421, ensuring vertical movement accuracy, reducing uneven wear, and improving welding consistency; on the other hand, the waist holes 462 opened on both sides of the limiting block 46 can restrict the movement path of the upper pin 47, ensuring the precise movement trajectory of the connecting rod 44 and improving welding stability.

[0046] The outer diameter of the sleeve 421 matches the inner diameter of the vertical hole 461, allowing the sleeve 421 to move along the length of the vertical hole 461. During the high-frequency vibration of the upper friction head 43, the limiting block 46 restricts the radial position of the sleeve 421, which not only improves the stability of the entire welding assembly 40 but also prevents the piston rod of the pressurizing cylinder 42 from being subjected to bending moment during the operation of the upper friction head 43 driven by the drive arm 45, thus improving the service life of the pressurizing cylinder 42.

[0047] The welding assembly 40 also includes a movable plate 20 and a lower friction head 22. The movable plate 20 is provided with a conveying channel 21, which is located below the upper friction head 43.

[0048] The lower friction head 22 is located at the bottom of the conveying channel 21, and the friction surface of the lower friction head 22 is arranged opposite to the upper friction head 43.

[0049] The friction head drive mechanism includes a reduction gearbox 491 and a welding motor 492. The reduction gearbox 491 is fixed to the moving plate 20. The reduction gearbox 491 includes a power input end and a power output end. The power output end is connected to the drive arm 45.

[0050] The shaft of the welding motor 492 is connected to the power input end of the gearbox 491. The welding motor 492 drives the upper friction head 43 to vibrate through the gearbox 491 and the drive arm 45.

[0051] The materials to be welded can be an upper and lower strip stacked together. The friction surfaces of the upper friction head 43 and the lower friction head 22 are provided with protrusions. The protrusions of the upper friction head 43 and the lower friction head 22 can penetrate the stacked upper and lower strips respectively. In this way, the relative position of the upper friction head 43 and the upper strip is determined, and the relative position of the lower friction head 22 and the lower strip is fixed. The upper and lower strips rub against each other at high frequency to ensure the welding quality of friction welding.

[0052] like Figure 8 and Figure 9 As shown, the conveying channel 21 includes a conveying trough 211, and a top cover 212 is provided on the conveying trough 211. The welding assembly 40 also includes a limiting member 80, which is disposed on the top cover 212. The limiting member 80 is located on one or both sides of the upper friction head 43, and the limiting member 80 limits the conveying width of the conveying channel 21.

[0053] The conveying trough 211 and the upper cover 212 enclose each other to form a conveying channel 21 for the strip, and the limiting member 80 is provided on the upper cover 212.

[0054] The limiting component 80 can constrain the position of the strip, prevent the first and second strips from misaligning during welding, and improve welding quality.

[0055] The limiting component 80 includes limiting plates 81 and limiting posts 82. One end of the two limiting plates 81 is hinged to the upper cover 212, and the upper end of the two limiting posts 82 is fixed to the other end of the limiting plates 81. The limiting posts 82 are located in the conveying channel 21, and the two limiting posts 82 can be adjusted along the width of the groove of the conveying channel 21.

[0056] The adjustable spacing between the two limit posts 82 can accommodate strips of different widths, making the welding assembly 40 more versatile.

[0057] like Figure 8 As shown, the strip splicing device includes the aforementioned welding assembly 40.

[0058] The conveying channel 21 has an inlet 21a and an outlet 21b at its two ends. The strip splicing device also includes a cutting assembly 30, a welding assembly 40, a limiting member 80, a side milling assembly 50, a limiting member 80, a vertical milling assembly 60, and a conveying assembly 70 arranged sequentially along the conveying direction on the conveying channel 21. The conveying assembly 70 includes a conveying motor 71 and a conveying pressure roller 72.

[0059] The above descriptions are merely some embodiments of this utility model.
