Description

Technical Field

[0001] This utility model relates to the field of tools for tightening fasteners, and specifically to a receiving module. Background Technology

[0002] In the automotive and other parts assembly industries, automated screw tightening technology is gradually replacing traditional manual tightening methods due to its reliability, efficiency, and traceability, and is gaining increasingly widespread application.

[0003] During the assembly process on the production line, screws are mostly fed from the hopper to the receiving module using air blowing. To improve the machine's cycle time, the air volume during screw feeding is increased, allowing the screw's end speed to reach over 15 m / s. For heavier screws, the screw head is more susceptible to damage from impact when entering the receiving module. This can lead to torque loss during automatic tightening, ultimately causing screw failure. Utility Model Content

[0004] This utility model provides a receiving module that can reduce damage to screws when receiving them.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A receiving module includes a base, a receiving cylinder, a driving mechanism, and a buffer device. The receiving cylinder and the driving mechanism are disposed on the base. The buffer device is slidably disposed within the base relative to the base under the drive of the driving mechanism. The buffer device includes a storage block, a buffer block, and an elastic element. A receiving cavity for accommodating screws is provided in the buffer block. The buffer block is movably disposed within the storage block. The elastic element is disposed between the buffer block and the storage block to buffer the impact force when the screw falls through its own deformation.

[0006] Preferably, there are multiple elastic elements, and the multiple elastic elements are arranged around the axis of the receiving cavity.

[0007] Preferably, the buffer block has an opening that extends vertically through the receiving cavity, and an opening corresponding to the receiving cavity is formed at the bottom of the storage block, and at least a portion of the opening of the receiving cavity is smaller than the size of the screw head.

[0008] Preferably, in a cross-section perpendicular to the axis of the accommodating cavity, the cross-sectional area of ​​the accommodating cavity gradually decreases from top to bottom.

[0009] Preferably, the storage block includes a base block and a pad block, wherein the pad block is detachably disposed within the base block and the buffer block is detachably disposed within the pad block.

[0010] Preferably, an anti-rotation pin is also provided in the buffer device, the anti-rotation pin being connected between the buffer block and the pad block.

[0011] Preferably, an elongated hole is provided on the outer side wall of the buffer block, and an installation hole penetrating the pad is provided on the pad block, wherein the anti-rotation pin passes through the installation hole and extends into the elongated hole.

[0012] Preferably, a receiving groove is formed on the substrate, the buffer device is slidably disposed in the receiving groove, and the receiving cylinder is vertically disposed above the receiving groove.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a receiving module that can reduce damage to screws when receiving them.

[0030] Please refer to Figures 1 to 4The receiving module provided by this utility model includes a base 10, a receiving cylinder 20, a driving mechanism 30, and a buffer device 40. The receiving cylinder 20 and the driving mechanism 30 are disposed on the base 10. The buffer device 40 is slidably disposed within the base 10 relative to the base 10 under the drive of the driving mechanism 30, so that the buffer device 40 forms a first position (see...). Figure 4 ) and the second position (see Figure 3 In the first position, the buffer device 40 corresponds to the position of the receiving cylinder 20 to receive the screw 60; in the second position, the buffer device 40 is offset from the receiving cylinder 20 to expose the screw 60, thereby facilitating the subsequent tightening device to remove the screw.

[0031] In this embodiment, a receiving groove 11 is provided on the substrate 10, and the buffer device 40 is slidably disposed in the receiving groove 11. The receiving cylinder 20 is vertically disposed above the receiving groove 11.

[0032] The drive mechanism 30 includes a cylinder 31 and a push rod 32. The push rod 32 is reciprocally connected to the cylinder 31. The cylinder 31 is located at one end of the receiving groove 11. One end of the push rod 32 is connected to the cylinder 31, and the other end passes through the side wall of the base 10 and extends into the receiving groove 11 and is connected to the buffer device 40 to drive the buffer device 40 to move.

[0033] A connector 321 is formed at the end of the push rod 32 facing the buffer device 40, and a connecting groove 411 is formed on the side wall of the buffer device 40 facing the push rod 32 (see...). Figure 5 The connector 321 extends into the connecting groove 411 to complete the connection between the push rod 32 and the buffer device 40.

[0034] Furthermore, the connecting groove 411 is vertically continuous, so that the connection between the push rod 32 and the buffer device 40 can be completed at the same time as the buffer device 40 is installed in the receiving groove 11.

[0035] A groove 412 is formed on one of the outer side wall of the buffer device 40 and the inner side wall of the receiving groove 11, and a slide rail 111 is formed on the other side wall of the buffer device 40 and the inner side wall of the receiving groove 11. Preferably, the groove 412 is formed on the outer side wall of the buffer device 40, and the slide rail 111 is formed on the inner side wall of the buffer device 40. The cooperation between the groove 412 and the slide rail 111 allows the buffer device 40 to move relatively stably within the receiving groove 11.

[0036] During operation, firstly, the drive mechanism 30 can move the buffer device 40 to the first position (e.g., Figure 4The position of the buffer device 40 is shown, and the position of the buffer device 40 corresponds to the position of the receiving cylinder 20; the screw 60 can fall from the receiving cylinder 20 into the buffer device 40 by its own weight; then, the drive mechanism 30 can move the buffer device 40 to a second position (such as...). Figure 3 The location of the buffer device 40 shown is so that the tightening device can grip the screw 60.

[0037] Please continue to refer to Figures 5 to 9 ( Figure 6 The exploded structural diagram (omitting screw 60) in this embodiment shows that the buffer device 40 includes a storage block 41, a buffer block 42, and an elastic element 43. The buffer block 42 has a receiving cavity 421 for accommodating the screw 60. The buffer block 42 is movably positioned within the storage block 41. The elastic element 43 is positioned between the buffer block 42 and the storage block 41 to absorb the impact force of the screw 60 when it falls into the buffer block 42 through its own deformation. More specifically, the elastic element 43 is positioned between the bottom plate of the storage block 41 and the lower end face of the buffer block 42. When the buffer device 40 is in the first position, the receiving cavity 421 on the buffer block 42 corresponds to the position of the port of the receiving cylinder 20.

[0038] When screw 60 is dislodged from the receiving cylinder 20, it falls into the receiving cavity 421 of the buffer block 42. Due to its high speed at this point, screw 60 possesses kinetic energy. This energy causes the buffer block 42 to move downwards relative to the storage block 41, thereby deforming the elastic element 43. The deformation of the elastic element 43 buffers the kinetic energy of screw 60, preventing damage when it contacts the buffer block 42.

[0039] Furthermore, in this embodiment, there may be multiple elastic elements 43, which are arranged around the axis of the receiving cavity 421 to ensure the smooth movement of the buffer block 42.

[0040] Further reading is available upon request. Figure 8 and Figure 9 In this embodiment, the buffer block 42 has an opening extending vertically through the receiving cavity 421, and a corresponding opening is also formed at the bottom of the storage block 41. At least a portion of the openings in the receiving cavity 421 is smaller than the size of the screw head 60. With this arrangement, the screw head 60 can be supported within the receiving cavity 421 to facilitate the transmission of impact force. The screw shank 60 can pass through the receiving cavity 421 and the bottom of the storage block 41, extending beyond the storage block 41, so that the buffer device 40 is not affected by the length of the screw 60.

[0041] In this embodiment, the receiving cavity 421 can be funnel-shaped, that is, on a cross section perpendicular to the axis of the receiving cavity 421, from near the receiving cylinder 20 to far away from the receiving cylinder 20 (i.e., Figure 8 From top to bottom, the cross-sectional area of ​​the receiving cavity 421 gradually decreases. This facilitates the adjustment of the screw 60's position when it falls, and also allows the same receiving cavity 421 to be used for more screws 60.

[0042] Further, in this embodiment, the storage block 41 includes a base block 413 and a pad block 414. The pad block 414 is detachably disposed within the base block 413, and the buffer block 42 is detachably disposed within the pad block 414. That is, the pad block 414 is fitted over the buffer block 42, and the base block 413 is fitted over the pad block 414, with the pad block 414 located between the buffer block 42 and the base block 413. An elastic member 43 is formed between the bottom surface of the base block 413 and the lower end surface of the buffer block 42. The aforementioned connecting groove 411 and sliding groove 412 are both formed on the outer side wall of the base block 413.

[0043] With the above settings, different pads 414 and buffer blocks 42 can be replaced according to different screw models 60, so that the buffer device 40 can be used for more screws 60.

[0044] Please continue to refer to Figure 6 , Figure 9 and Figure 10 An anti-rotation pin 45 is also provided in the buffer device 40. The anti-rotation pin 45 is connected between the buffer block 42 and the pad block 414 to prevent the buffer block 42 and the pad block 414 from rotating.

[0045] More specifically, an elongated hole 422 is provided on the outer wall of the buffer block 42, and a mounting hole 4141 penetrating the pad 414 is provided on the pad 414. The anti-rotation pin 45 passes through the mounting hole 4141 and extends into the elongated hole 422 to complete the connection between the buffer block 42 and the pad 414. The elongated hole 422 also facilitates the up-and-down movement of the buffer block 42 relative to the pad 414.

[0046] In summary, in this invention, the buffer device 40 allows the screw 60 to fall into the buffer device 40, causing the buffer block 42 to move downwards, which in turn causes the elastic element 43 to deform. The deformation of the elastic element 43 can offset the impact of the screw 60 on the buffer block 42, thereby reducing damage to the screw 60.

[0047] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
