Description

Technical Field

[0001] This invention relates to the field of welding stud magnetic ring assembly technology, and more specifically, to a welding stud magnetic ring assembly machine. Background Technology

[0002] Welding studs are a type of high-strength, rigid fastener used in steel structures to provide rigid connections between different components. With the widespread use of welding studs in steel structures, the traditional welding process required two people: one to place the magnetic ring at the welding position, and another to hold the welding stud in one hand and assemble it onto the magnetic ring while simultaneously welding with a welding torch. To address the limitations of this traditional two-person operation, bolt welding carriages are now used to automatically weld welding studs and magnetic rings. However, these carriages cannot automatically feed or assemble the welding studs and magnetic rings, thus requiring further improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a welding stud magnetic ring assembly machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A welding stud and magnetic ring assembly machine includes a welding stud pusher, a magnetic ring pusher, and an output channel located between the welding stud pusher and the magnetic ring pusher. The welding stud pusher includes a welding stud flow channel, and the magnetic ring pusher includes a magnetic ring channel. The discharge end of both the welding stud flow channel and the magnetic ring channel is located at the inlet end of the output channel. The machine also includes a clamping assembly assembly for clamping and assembling the welding studs at the discharge end of the welding stud flow channel with the magnetic rings at the discharge end of the magnetic ring channel. A misalignment mechanism is provided at the discharge end of the magnetic ring channel and the inlet end of the output channel for conveying the assembled welding studs and magnetic rings from the discharge end of the magnetic ring channel to the inlet end of the output channel.

[0006] The output channel includes a first output guide rail, a second output guide rail, and a connecting guide rail connecting the first and second output guide rails. The connecting guide rail includes two connecting blocks, one of which has an infrared sensor mounted on its upper part. The infrared sensor is used to detect weld studs on the connecting guide rail. When the infrared sensor detects a weld stud, the weld stud and the magnetic ring are successfully assembled. When the infrared sensor does not detect a weld stud, the weld stud and the magnetic ring are not successfully assembled. A collection box is provided below the connecting guide rail, and a drive mechanism is also included to drive the two connecting blocks to move closer or further apart. When the infrared sensor does not detect a weld stud, the drive mechanism drives the two connecting blocks to move away from each other, causing the weld stud to fall into the collection box.

[0007] Preferably, the weld stud flow channel includes an inclined flow channel and a horizontal flow channel. The lower end of the inclined flow channel is connected to the horizontal flow channel. The horizontal flow channel is the discharge end of the weld stud flow channel, and the end of the horizontal flow channel away from the inclined flow channel is closed.

[0008] Preferably, it also includes a linear vibrator, with the magnetic ring feed channel mounted on the linear vibrator.

[0009] Preferably, the clamping assembly includes a horizontal electric guide rail, a vertical electric guide rail, and an electric clamp. A horizontal electric slider is slidably mounted on the horizontal electric guide rail, and a vertical electric slider is slidably mounted on the vertical electric guide rail. The electric clamp is mounted on the vertical electric slider, and the magnetic ring material channel and the horizontal flow channel are located on the same vertical plane.

[0010] Preferably, the misalignment mechanism includes a lifting plate and a second cylinder for driving the lifting plate to move up and down. The lifting plate is provided with a first groove and a second groove. The height of the first output guide rail is higher than the height of the magnetic ring channel. A push block is provided at the top of the lifting plate away from the first output guide rail. The mechanism also includes a third cylinder for driving the push block to push the welding stud magnetic ring on the lifting plate to the first output guide rail.

[0011] Preferably, a stop block is fixedly connected to the top of the lifting plate on the side away from the magnetic ring material channel.

[0012] Preferably, the drive mechanism includes two first cylinders located on both sides of the connecting guide rail, with the extended ends of the two first cylinders fixedly connected to the two connecting guide blocks respectively.

[0013] Preferably, it also includes a timer. The timer, infrared sensor, and first cylinder are all electrically connected to the controller. When the infrared sensor does not detect the welding nail, the controller controls the timer to work. When the timer reaches the set time and the infrared sensor still has not detected the welding nail, the controller controls the first cylinder to move the two connecting guide blocks away from each other so that the welding nail falls into the collection box. When the timer does not reach the set time and the infrared sensor detects the welding nail, the controller controls the timer to be reset to zero and stop working.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] First, the present invention can automatically feed welding studs by setting a welding stud pusher, automatically feed magnetic rings by setting a magnetic ring pusher, and assemble welding studs and magnetic rings by setting a clamping assembly assembly. The three are set together to automatically feed welding studs and magnetic rings and automatically assemble welding studs and magnetic rings.

[0016] Secondly, a misalignment mechanism and an output channel are set up so that after the welding stud and magnetic ring are assembled, the assembled welding stud and magnetic ring can be automatically transported to the output channel, and then the welding operation of the assembled welding stud and magnetic ring can be conveniently performed.

[0017] Finally, the output channel is set up with three parts: the first output guide rail, the second output guide rail, and the connecting guide rail. A collection box is set below the connecting guide rail. When the infrared sensor does not detect the welding nail within the set time, it means that the welding nail and the magnetic ring are not assembled. The drive mechanism can drive the two connecting guide blocks to move away from each other so that the welding nail falls into the collection box. Thus, the unassembled welding nails can be screened and dropped into the collection box. Attached Figure Description

[0037] This invention provides a technical solution:

[0038] Please refer to a welding stud magnetic ring assembly machine. Figures 1-14 It includes a base 1, a welding stud pusher 2, a magnetic ring pusher 3, and an output channel 41 located between the welding stud pusher 2 and the magnetic ring pusher 3; both the welding stud pusher 2 and the magnetic ring pusher 3 are located on the base 1.

[0039] Please see Figure 1 and Figure 4 The stud pusher 2 includes a stud flow channel 25, which is used to convey the studs 7 pushed out by the stud pusher 2. The magnetic ring pusher 3 includes a magnetic ring feed channel 35, which is used to convey the magnetic rings 8 pushed out by the magnetic ring pusher 3. The discharge end of the stud flow channel 25 and the discharge end of the magnetic ring feed channel 35 are both located at the feed end of the output feed channel 41. Except for the stud flow channel 25, the other components of the stud pusher 2 and the magnetic ring pusher 3 are the same and are all existing conventional designs.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 13 , Figure 14 To facilitate understanding of the welding stud pusher 2 and the magnetic ring pusher 3, a brief introduction is provided below. The welding stud pusher 2 includes a first base plate 20 and two parallel first side plates 21. The lower part of the first side plates 21 is fixedly connected to the first base plate 20. Several first support plates 23 are arranged in a stepped manner between the two first side plates 21. The two sides of the first support plates 23 are fixedly connected to the two first side plates 21 respectively. A first gap is provided between two adjacent first support plates 23. A first pusher 24 is movably mounted in the first gap. A welding stud material plate 22 is fixedly connected between the two first side plates 21. The welding stud material plate 22 is located in front of the first support plates 23. The welding stud material plate 22 is inclined (for example, the inclination is greater than 35°). The lower end of the inclined welding stud material plate 22 faces the first support plate 23. A gap with the same first gap as the first gap is also provided between the welding stud material plate 22 and the foremost first support plate 23. A first pusher 24 can also be movably mounted in this gap.

[0041] The front surface of the first support plate 23 is inclined, and the top of the first support plate 23 and the first push plate 24 are both inclined. When the first push plate 24 is raised to the bottom, the top of the first push plate 24 is flush with the top of the first support plate 23 or the top of the first push plate 24 is flush with the welding stud plate 22. When the first push plate 24 is raised to the top, the top of all the first push plates 24 is flush with the top of the first support plate 23.

[0042] A first mounting groove is provided on the first side plate 21, and a weld stud flow channel 25 is fixedly installed in the first mounting groove. The front side wall of the weld stud flow channel 25 abuts against the rear side wall of the last support plate 23. (See reference) Figure 14 It also includes a connecting plate 26, the rear sidewall of each first push plate 24 is fixedly connected to the connecting plate 26, and a driving component for driving the connecting plate 26 to move up and down. The driving component here can be a cylinder, which is mounted on the first base plate 20, and the piston rod end of the cylinder is fixedly connected to the connecting plate 26.

[0043] When in use, the welding stud 7 is placed on the welding stud material plate 22. The welding stud 7 slides along the inclined surface of the welding stud material plate 22 toward the first support plate 23. The driving component drives the connecting plate 26 to rise and fall, thereby driving the first push plate 24 to rise and fall. Each time the flat welding stud is pushed up, when the welding stud is pushed to the top of the first support plate 23, the welding stud will fall into the welding stud flow channel 25.

[0044] Of course, based on the structure of the welding stud pusher 2, we can know the structure of the magnetic ring pusher 3. The magnetic ring pusher 3 includes a second base plate 30 and two parallel second side plates 31. The lower part of the second side plates 31 is fixedly connected to the second base plate 30. Several second support plates 33 are arranged in a stepped manner between the two second side plates 31. The two sides of the second support plates 33 are fixedly connected to the two second side plates 31 respectively. A second gap is provided between two adjacent second support plates 33. A second pusher 34 is movably mounted in the second gap. A magnetic ring material plate 32 is fixedly connected between the two second side plates 31. The magnetic ring material plate 32 is located in front of the second support plates 33. The magnetic ring material plate 32 is inclined, with the lower end of the inclined magnetic ring material plate 32 facing the second support plate 33. A gap with the same second gap is also provided between the magnetic ring material plate 32 and the foremost second support plate 33. A second pusher 34 can also be movably mounted in this gap.

[0045] The front surface of the second support plate 33 is inclined, and the top of the second support plate 33 and the second push plate 34 are both inclined. When the second push plate 34 is raised to the bottom, the top of the second push plate 34 is flush with the top of the second support plate 33 or the top of the second push plate 34 is flush with the magnetic ring material plate 32. When the second push plate 34 is raised to the top, the top of all the second push plates 34 is flush with the top of the second support plate 33.

[0046] A second mounting groove is provided on the second side plate 31, and the magnetic ring material channel 35 is located in the second mounting groove. The front side wall of the magnetic ring material channel 35 abuts against the rear side wall of the second support plate 33 located at the rearmost end. It also includes a connecting frame. The rear side wall of each second push plate 34 is fixedly connected to the connecting frame. It also includes a driving component for driving the connecting frame to lift. The driving component here can be a cylinder. The cylinder is installed on the second base plate 30, and the piston rod end of the cylinder is fixedly connected to the connecting frame. Of course, the driving component can also be a hydraulic cylinder or a motor plus a reducer cam drive.

[0047] When in use, the magnetic ring is placed on the magnetic ring material plate 32, and the driving component drives the connecting frame to rise and fall, thereby driving the second push plate 34 to rise and fall. Each time the flat magnetic ring is pushed up, when the magnetic ring is pushed to the top of the second support plate 33 at the top, the magnetic ring will fall into the magnetic ring material channel 35.

[0048] Of course, in order to prevent the pushed welding studs from falling from the rear of the welding stud flow channel 25, a first baffle that abuts against the rear side of the welding stud flow channel 25 can be provided on the rear side of the welding stud flow channel 25, and the first baffle is fixedly connected to the first side plate.

[0049] To prevent the pushed magnetic ring from falling off the rear of the magnetic ring feed channel 35, a second baffle that abuts against the rear side of the magnetic ring feed channel 35 can be provided on the rear side of the magnetic ring feed channel 35, and the second baffle is fixedly connected to the second side plate.

[0050] The stud flow channel 25 includes an inclined flow channel and a horizontal flow channel that are interconnected. The lower end of the inclined flow channel is connected to the horizontal flow channel, and the horizontal flow channel is the discharge end of the stud flow channel 25. When the stud falls into the stud flow channel 25, it first slides from the inclined flow channel to the horizontal flow channel under the action of gravity. The end of the horizontal flow channel away from the inclined flow channel is closed (to prevent the stud from sliding out of the horizontal flow channel).

[0051] It also includes a linear vibrator, with a magnetic ring feed channel 35 mounted on it. The rear side of the magnetic ring feed channel 35 can slide relative to the second baffle. When the linear vibrator is working, it can drive the magnetic ring feed channel 35 to vibrate linearly and convey the magnetic rings linearly. This linear conveying method is the same as that of existing linear vibrators and is existing technology, so it will not be described in detail here.

[0052] See Figures 7-8 The output channel 41 includes a first output guide rail 410, a second output guide rail 411, and a connecting guide rail connecting the first output guide rail 410 and the second output guide rail 411. Both the first output guide rail 410 and the second output guide rail 411 include two symmetrical L-shaped guide blocks, and a conveying channel is formed between the two symmetrical L-shaped guide blocks.

[0053] The connecting guide rail includes two connecting guide blocks 412, which are arranged symmetrically in an L-shape. The front and rear ends of the connecting guide rail abut against the first output guide rail 410 and the second output guide rail 411, respectively.

[0054] It also includes a support platform 40, with several support columns fixedly connected to the bottom of the support platform 40. The bottom ends of the support columns are fixedly connected to the base 1. In use, support rods are fixedly connected to the bottom of the first output rail 410 and the second output rail 411. The bottom ends of the support rods are fixedly connected to the support platform 40, which is used to support the first output rail 410 and the second output rail 411 above the support platform 40.

[0055] It also includes a clamping assembly assembly, which is used to clamp the weld studs at the discharge end of the weld stud flow channel 25 and assemble them with the magnetic rings at the discharge end of the magnetic ring material channel 35. Assembly means inserting the weld studs into the magnetic rings.

[0056] For details, please refer to Figures 4-5 The clamping assembly includes a horizontal electric guide rail 51, a vertical electric guide rail 53, and an electric clamp 55. It also includes a support frame 50, the bottom of which is fixedly connected to the base 1, and the support frame 50 is fixedly connected to the support platform 40. The horizontal electric guide rail 51 is mounted on the support frame 50, and a horizontal electric slider 52 slides on the horizontal electric guide rail 51. The vertical electric guide rail 53 is mounted on the horizontal electric slider 52, and a vertical electric slider 54 slides on the vertical electric guide rail 53. The electric clamp 55 is mounted on the vertical electric slider 54. The magnetic ring channel 35 and the horizontal flow channel are located in the same... On a vertical plane, the electric clamp 55 is located above the magnetic ring material channel 35 and the horizontal flow channel; the horizontal electric slider 52 moves on the horizontal electric guide rail 51 to adjust the electric clamp 55 to move horizontally above the welding stud flow channel 25 or the magnetic ring material channel 35. After the electric clamp 55 moves above the welding stud flow channel 25, the vertical electric slider 54 is adjusted to move on the vertical electric guide rail 53 to adjust the distance between the electric clamp 55 and the welding stud, so as to facilitate the clamping of the welding stud; after the electric clamp 55 clamps the welding stud, it moves horizontally to above the discharge end of the magnetic ring material channel 35, and then moves the welding stud downward to assemble the welding stud with the magnetic ring.

[0057] It should be added that the horizontal electric guide rail 51, the horizontal electric slider 52, the vertical electric guide rail 53, the vertical electric slider 54, and the electric clamp 55 are all existing conventional technologies. The cooperation between the electric slider and the electric guide rail is also a mature technology with a large number of published documents, so it will not be elaborated on here.

[0058] See Figure 4 The discharge end of the magnetic ring material channel 35 and the inlet end of the output material channel 41 are provided with a misalignment mechanism 6. The misalignment mechanism 6 is used to transport the welded stud magnetic ring assembled at the discharge end of the magnetic ring material channel 35 to the inlet end of the output material channel 41.

[0059] For details, please refer to Figures 9-12The misalignment mechanism 6 includes a lifting plate 60 and a second cylinder 64 for driving the lifting plate 60 to rise and fall. The second cylinder 64 is fixedly mounted on the support platform 40 by bolts. The lifting plate 60 is provided with a first groove 61 and a second groove 62. The first groove 61 is arranged along the length direction of the magnetic ring material channel 35, and the second groove 62 is arranged along the length direction of the first output guide rail 410. When the lifting plate 60 rises and falls to be aligned with the first output guide rail 410, the second groove 62 is aligned with the conveying channel of the first output guide rail 410, which allows the welding studs to be aligned. The first output guide rail 410 is entered from the second groove 62; the height of the first output guide rail 410 is higher than the height of the magnetic ring channel 35. A push block 66 is provided at the top of the lifting plate 60 away from the first output guide rail 410. The third cylinder 67 is mounted on the support frame 50 by bolts. The piston rod end of the third cylinder 67 is fixedly connected to the push block 66. The height of the push block 66 is the same as the height of the first output guide rail 410.

[0060] After the magnetic rings on the magnetic ring feed channel 35 are conveyed to the lifting plate 60, the clamping assembly assembly assembles the welding studs at the discharge end of the welding stud flow channel 25 with the magnetic rings conveyed to the lifting plate 60. After the welding studs and magnetic rings are assembled, the second cylinder 64 pushes the lifting plate 60 to the height of the first output guide rail 410. Then, the third cylinder 67 pushes the push block 66, causing the push block 66 to push the magnetic rings and welding studs to move onto the first output guide rail 410. After the magnetic rings and welding studs move onto the first output guide rail 410, the second cylinder 64 drives the lifting plate 60 to descend to the height of the magnetic ring feed channel 35. Then, the linear vibrator continues to drive the magnetic ring feed channel 35 to vibrate, so that the magnetic rings on the magnetic ring feed channel 35 are conveyed to the lifting plate 60. Then, the above steps are repeated.

[0061] It should be added that, starting from when the first magnetic ring is conveyed to the lifting plate 60, the next magnetic ring will not be conveyed until the welding stud and the magnetic ring are assembled and then conveyed to the first output guide rail 410, and the lifting plate 60 descends to the height position of the magnetic ring material channel 35. In addition, each time the welding stud and magnetic ring after the next assembly are conveyed to the first output guide rail 410, it will push the welding stud and magnetic ring conveyed to the first output guide rail 410 forward.

[0062] To prevent the magnetic rings conveyed from the magnetic ring feed channel 35 to the lifting plate 60 from falling off, a stop block 63 is fixedly connected to the top of the lifting plate 60 on the side away from the magnetic ring feed channel 35; the stop block 63 can effectively block the magnetic rings and prevent them from falling off.

[0063] See Figure 7An infrared sensor 43 is fixedly mounted on the upper part of one of the connecting guide blocks 412. The infrared sensor 43 is used to detect the welding studs on the connecting guide rail, specifically detecting the height of the welding studs on the connecting guide rail. When the infrared sensor 43 detects the welding stud, the welding stud and the magnetic ring are successfully assembled. Because the height of the welding stud increases after the welding stud and the magnetic ring are combined, the infrared sensor 43 can detect the welding stud when it passes the position of the welding stud. When the infrared sensor 43 does not detect the welding stud, the welding stud and the magnetic ring are not successfully assembled. If the welding stud and the magnetic ring are not successfully assembled, the height of the welding stud on the connecting guide rail will not reach the height of the infrared sensor 43. In this case, the welding stud cannot be detected when it reaches the connecting guide rail. In this way, the welding stud can be detected effectively, so as to know whether the welding stud and the magnetic ring are properly assembled.

[0064] See Figure 4 , Figure 6 , Figure 7 , Figure 8 A collection box 44 is provided below the connecting guide rail. The collection box 44 is placed on the support platform 40. It also includes a drive mechanism that drives two connecting guide blocks 412 to move closer or further apart. When the infrared sensor 43 does not detect the welding nail, the drive mechanism drives the two connecting guide blocks 412 to move further apart so that the welding nail falls into the collection box 44. When the infrared sensor 43 does not detect the welding nail, it means that the welding nail and the magnetic ring are not assembled, so that the unassembled welding nail can be screened and dropped into the collection box 44.

[0065] Specifically, the drive mechanism includes two first cylinders 42 located on both sides of the connecting guide rail. The extended ends of the two first cylinders 42 are fixedly connected to two connecting guide blocks 412 respectively. The two first cylinders 42 can be installed on the first side plate and the second side plate respectively according to actual needs.

[0066] Because small gaps inevitably exist between adjacent assembled weld studs and magnetic rings when they are conveyed on the output channel 41, when the infrared sensor 43 illuminates the gap between two assembled weld studs and magnetic rings, there may be a brief period when no weld stud is detected. This does not mean that the weld stud and magnetic ring are not assembled. To solve this technical problem, the following technical solution is proposed:

[0067] It also includes a timer. The timer, infrared sensor 43 and first cylinder 42 are all electrically connected to the controller. When the infrared sensor 43 does not detect the welding nail, the controller controls the timer to work. When the timer reaches the set value, the infrared sensor 43 still has not detected the welding nail. At this time, it means that the welding nail connected to the connecting guide rail has not been assembled with the magnetic ring. The controller controls the first cylinder 42 to drive the two connecting guide blocks 412 away from each other so that the welding nail falls into the collection box 44.

[0068] When the infrared sensor 43 does not detect the welding nail, the controller controls the timer to work. When the timer counts for less than the set time, the infrared sensor 43 detects the welding nail, which means that there is a small gap between two adjacent assembled welding nails and magnetic rings. At this time, the welding nail and magnetic ring are assembled. The controller controls the timer to reset to zero and stop working. The controller will control the timer to work again when the infrared sensor 43 does not detect the welding nail again.

[0069] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.

It also includes a clamping assembly assembly, which is used to clamp the welding studs at the discharge end of the welding stud flow channel (25) and assemble them with the magnetic rings at the discharge end of the magnetic ring material channel (35). The discharge end of the magnetic ring material channel (35) and the inlet end of the output material channel (41) are provided with a misalignment mechanism (6). The misalignment mechanism (6) is used to transport the assembled welding stud magnetic rings at the discharge end of the magnetic ring material channel (35) to the inlet end of the output material channel (41). The misalignment mechanism (6) includes a lifting plate (60) and a second cylinder (64) for driving the lifting plate (60) to rise and fall. The second cylinder (64) is fixedly mounted on the support platform (40) by bolts. The lifting plate (60) is provided with a first groove (61) and a second groove (62). The first groove (61) is arranged along the length direction of the magnetic ring material channel (35), and the second groove (62) is arranged along the length direction of the first output guide rail (410). When the lifting plate (60) rises and falls to be aligned with the first output guide rail (410), the second groove (62) is aligned with the conveying channel of the first output guide rail (410), which allows the welding studs to be aligned. The first output guide rail (410) is entered from the second groove (62); the height of the first output guide rail (410) is higher than the height of the magnetic ring channel (35); a push block (66) is provided at the top of the lifting plate (60) away from the first output guide rail (410); the third cylinder (67) of the first output guide rail (410) is also included, which drives the push block (66) to push the welded magnetic ring on the lifting plate (60) to the third cylinder (67) of the first output guide rail (410); the third cylinder (67) is installed on the support frame (50) by bolts; the piston rod end of the third cylinder (67) is fixedly connected to the push block (66); the height of the push block (66) is the same as the height of the first output guide rail (410); The misalignment mechanism (6) is configured such that: after the magnetic ring on the magnetic ring channel (35) is conveyed to the lifting plate (60), the clamping assembly assembly assembles the welding nail at the discharge end of the welding nail channel (25) with the magnetic ring conveyed to the lifting plate (60). After the welding nail and the magnetic ring are assembled, the second cylinder (64) pushes the lifting plate (60) to rise to the height of the first output guide rail (410), and then the third cylinder (67) pushes the push block (66) so that the push block (66) pushes the magnetic ring and the welding nail to move to the first output guide rail (410). After the magnetic ring and the welding nail move to the first output guide rail (410), the second cylinder (64) drives the lifting plate (60) to fall to the height of the magnetic ring channel (35). The output channel (41) includes a first output guide rail (410), a second output guide rail (411), and a connecting guide rail connecting the first output guide rail (410) and the second output guide rail (411). The connecting guide rail includes two connecting guide blocks (412), one of which is equipped with an infrared sensor (43). The infrared sensor (43) is used to detect the welding studs on the connecting guide rail. When the infrared sensor (43) detects the welding studs, the welding studs and magnetic rings are successfully assembled. When the infrared sensor (43) does not detect the welding studs, the welding studs and magnetic rings are not successfully assembled. A collection box (44) is provided below the connecting guide rail. It also includes a driving mechanism that drives the two connecting guide blocks (412) to move closer or further away from each other. When the infrared sensor (43) does not detect the welding studs, the driving mechanism drives the two connecting guide blocks (412) to move further away from each other, causing the welding studs to fall into the collection box (44).
