Description

Technical Field

[0001] This utility model relates to the field of riveting technology, and in particular to a multi-hole bracket riveting machine. Background Technology

[0002] In the automotive parts industry, multi-hole brackets are a common type of component. They are mostly long and strip-shaped with multiple holes on a plane and multiple nuts installed at corresponding positions by riveting. They are used for installation and connection with other components, such as car radiator brackets, condenser brackets, and battery brackets.

[0003] Traditional multi-hole bracket riveting processes mainly rely on manual, multiple riveting operations. However, with technological advancements, a riveting device for automotive radiator condenser brackets, patent number CN202321921944.3, has emerged to improve riveting efficiency. This device uses clamping components on a translation assembly to fix the bracket and move it left and right, achieving automated riveting in conjunction with the riveting assembly, thereby effectively reducing the degree of manual intervention.

[0004] However, in practical applications, it has been found that during the processing of multi-hole brackets, a certain range of machining errors is permissible. Furthermore, errors are unavoidable when clamping the brackets. This often results in the holes shifting after the multi-hole brackets are clamped. The translation component moves the bracket to below the riveting component according to pre-set fixed parameters. When hole errors occur, the translation component cannot adjust accordingly, causing the riveting position to not precisely align with the hole, leading to riveting failure and reduced processing quality.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed by the present invention. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit the present invention.

[0020] like Figures 1 to 7 As shown in the figure, a multi-hole bracket riveting machine according to an embodiment of the present invention includes a worktable 100, a clamping assembly 200, a three-coordinate translation stage 300, a vision recognition assembly 400, a riveting assembly 500, and a control assembly 600.

[0021] The clamping assembly 200 is mounted on the workbench 100 and is used to clamp the multi-hole bracket in conjunction with the workbench 100. In fact, the clamping assembly 200 can take various forms such as a clamping cylinder or a bolt cutter. The clamping assembly 200, in conjunction with the workbench 100, can press the upper and lower sides of the multi-hole bracket from above (avoiding the opening positions of the multi-hole bracket), or clamp the front and rear sides of the multi-hole bracket, thereby firmly fixing the multi-hole bracket on the workbench 100, thus preparing for the subsequent riveting operation to be performed on the multi-hole bracket.

[0022] The three-coordinate translation stage 300 is mounted on the worktable 100 and has a connecting frame 310 at its output end. The three-coordinate translation stage 300 can be a multi-axis linkage structure composed of a lead screw and nut pair, a synchronous belt drive mechanism, and a gear and rack pair, which can drive the connecting frame 310 to move in all directions in three-dimensional space, providing conditions for accurately adjusting the front-back, left-right, and up-down positions of the riveting assembly 500.

[0023] The visual recognition component 400 is mounted on the connecting frame 310 and is used to identify the position parameters of the rivet holes on the multi-hole bracket. The visual recognition component 400 typically includes an industrial camera or lens, which can acquire image information of the rivet holes on the multi-hole bracket. Subsequently, the image is analyzed by an image processing algorithm to accurately extract the position parameters of the rivet holes (such as the center coordinates of the holes), providing correction parameters for subsequent adjustment of the movement path of the three-coordinate translation stage 300.

[0024] The riveting assembly 500 is mounted on the connecting frame 310 and used to rivet the riveting holes on the multi-hole bracket. In fact, the riveting assembly 500 can be a riveting gun, mounted on the connecting frame 310 and driven by the three-coordinate translation stage 300 to move back and forth, left and right, and up and down, so as to rivet multiple riveting holes on the multi-hole bracket.

[0025] The control component 600 is communicatively connected to the three-coordinate translation stage 300, the vision recognition component 400, and the riveting component 500. The control component 600 can be a PLC (Programmable Logic Controller), an industrial computer, an embedded controller, etc., and can control the operation of the three-coordinate translation stage 300 and the riveting component 500. It has a built-in processing algorithm to obtain the data recognized by the vision recognition component 400 in order to calculate the deviation of the riveting hole position on the multi-hole bracket.

[0026] The specific working principle of the multi-hole bracket riveting machine of this utility model is as follows: The multi-hole bracket is clamped on the worktable 100 by the clamping component 200, and the working path and action of the three-coordinate translation stage 300 and the riveting component 500 are set on the control component 600; During the process of the three-coordinate translation stage 300 driving the vision recognition component 400 to move, the vision recognition component 400 obtains the position parameters of the riveting holes on the multi-hole bracket and transmits these parameters to the control component 600; The control component 600 analyzes the deviation between the actual position and the ideal position of the riveting hole, and then calculates the corresponding correction parameters. The control component 600 sends the correction path instruction to the three-coordinate translation stage 300, drives the three-coordinate translation stage 300 to drive the riveting component 500 to move to the correction riveting position according to the correction path, so that it accurately reaches the correction hole position and rivets the riveting hole.

[0027] The multi-hole bracket riveting machine of this utility model, through the cooperation of a worktable 100, a clamping component 200, a three-coordinate translation stage 300, a vision recognition component 400, a riveting component 500, and a control component 600, can correct the movement path and riveting position of the riveting component 500, compensate for the hole position deviation of the riveting hole, reduce the probability of riveting failure, and improve the processing quality.

[0028] It should be noted that the multi-hole bracket riveting machine of this utility model preferably includes a support frame 700 for supporting the multi-hole bracket and placing it on the worktable 100. The support frame 700 is provided with a plurality of limiting grooves 710 for limiting the front and rear sides of the multi-hole bracket. The clamping assembly 200 includes a first clamping mechanism 210 with an output end for pressing the multi-hole bracket. In fact, the distance between the front and rear sides of the limiting grooves 710 matches the distance between the front and rear sides of the multi-hole bracket, which can limit the front and rear position of the multi-hole bracket and play a positioning role. In actual operation, the multi-hole bracket is first placed on the support frame 700, and the limiting grooves 710 are used to complete the initial positioning. Then, the first clamping mechanism 210 in the clamping assembly 200 fixes the multi-hole bracket together with the support frame 700 on the worktable 100, reducing the difficulty of positioning the multi-hole bracket on the worktable 100.

[0029] Specifically, the support frame 700 preferably has a forward-facing triangular insertion block 720, and the worktable 100 has a rearward-facing V-shaped groove 110 that matches the triangular insertion block 720. The cooperation between the triangular insertion block 720 and the V-shaped groove enables rapid positioning. In practice, the specific dimensions of the support frame 700 can be adjusted according to the dimensions of different perforated supports, but the position of the triangular insertion block 720 remains unchanged. This ensures rapid positioning while also allowing for the adaptation to various perforated supports of different sizes within a certain range, greatly improving the versatility and flexibility of the device.

[0030] More specifically, the clamping assembly 200 preferably includes a second clamping mechanism 220 at its output end for clamping the support bracket 700. In practice, the first clamping mechanism 210 and the clamping mechanism can take various forms such as clamping cylinders or vises. The first clamping mechanism 210 is mainly responsible for clamping the perforated bracket, while the second clamping mechanism 220 focuses on clamping the support bracket 700. The two cooperate to fix the perforated bracket and the support bracket 700. Through the cooperation of the first clamping mechanism 210 and the second clamping mechanism 220, not only is the overall stability of the perforated bracket and the support bracket 700 enhanced, but riveting deviations caused by the wobbling of the support bracket 700 are also avoided, thereby improving the riveting quality.

[0031] It should be noted that the riveting assembly 500 preferably includes a riveting frame 510 that is slidably connected to the connecting frame 310, springs 520 whose upper and lower ends are respectively connected to the connecting frame 310 and the riveting frame 510, a riveting gun 530 mounted on the riveting frame 510, and a control cylinder 540 mounted on the riveting frame 510 for controlling the operation of the riveting gun 530. The control cylinder 540 is communicatively connected to the control assembly 600. Figure 4 As shown, the output end of the control cylinder 540 extends below the control button of the riveting gun 530. When the output end of the control cylinder 540 rises to press the control button of the riveting gun 530, the riveting gun 530 operates; when the output end of the control cylinder 540 descends to leave the control button of the riveting gun 530, the riveting gun 530 stops operating. Furthermore, the control cylinder 540 is communicatively connected to the control component 600, enabling precise control of the cylinder's movement and thus improving automation. In practice, the spring 520 connects the riveting bracket 510 and the connecting bracket 310, allowing the riveting gun 530 to float elastically relative to the connecting bracket 310. When the riveting gun 530 moves down to contact the riveting hole, the elastic deformation of the spring 520 absorbs the impact force, preventing rigid collisions during riveting, reducing damage to the riveting gun 530 and the multi-hole bracket, and extending its service life.

[0032] It is worth mentioning that the riveting gun 530 preferably has a riveting head 531 for moving the rivets, and the worktable 100 is equipped with a feeding assembly 800 for outputting the rivets one by one and having them attracted by the riveting head 531. In practice, the riveting head 531 can be magnetic or vacuum-adhesive. Magnetic riveting heads 531 rely on magnetic force to attract rivets and are suitable for magnetic rivets; vacuum-adhesive riveting heads 531 attract rivets through negative pressure and are suitable for rivets of various materials. Common types of feeding assemblies 800 include vibratory feeder 810 feeding and track feeding. During operation, the feeding assembly 800 first delivers the rivets one by one to the working range of the riveting head 531. The riveting head 531 attracts the rivets, and then the riveting gun 530 moves the riveting head 531, which holds the rivets, to above the riveting holes of the multi-hole bracket, completing the riveting action. By automatically transferring the rivets into the riveting holes of the multi-hole bracket, the automation level of the riveting process is improved, and manual intervention is reduced.

[0033] Specifically, the feeding assembly 800 preferably includes a vibratory feeder 810 for outputting rivets one by one, a guide rail 820 extending left and right with its inlet connected to the output end of the vibratory feeder 810, a feeding seat 830 connected to the guide rail 820 and installed on the worktable 100, and a pushing device 840 installed on the worktable 100. The feeding seat 830 is provided with a guide channel 831 connected to the outlet of the guide rail 820 and extending front and rear, and a feeding groove 832 connected to the rear end of the guide channel 831. The pushing device 840 includes a pushing cylinder 841 installed on the worktable 100 and located in front of the feeding seat 830, and a push rod 842 installed at the output end of the pushing cylinder 841 for pushing the rivets from the outlet of the guide rail 820 into the guide channel 831 and into the feeding groove 832. The vibratory feeder 810 and the pushing cylinder 841 are both communicatively connected to the control assembly 600. During operation, the vibratory feeder 810 automatically arranges the scattered rivets through vibration and transports them to the guide rail 820. The guide rail 820 guides the rivets to move along a fixed path to the material guide channel 831. Under the command of the control component 600, the pusher cylinder 841 drives the push rod 842 to precisely push the rivets, so that the rivets enter the material guide channel 831 and the feeding trough 832 in sequence, realizing the movement of the rivets one by one to the feeding trough 832 for the rivet head 531 to absorb the rivets. This realizes the automatic and orderly feeding of rivets and ensures that the rivets are accurately delivered to the feeding trough 832.

[0034] Furthermore, the feeding assembly 800 preferably includes a first photoelectric switch 850 mounted on the feeding base 830 for detecting rivets in the feeding slot 832. The first photoelectric switch 850 is communicatively connected to the control assembly 600. During operation, when there are no rivets in the feeding slot 832, the first photoelectric switch 850 transmits a signal to the control assembly 600. The control assembly 600 then activates the pusher cylinder 841 to drive the push rod 842 to push the rivets from the guide rail 820 outlet into the guide channel 831 and into the feeding slot 832. If there are already rivets in the feeding slot 832, the first photoelectric switch 850 sends a feedback signal to the control assembly 600, and the control assembly 600 keeps the pusher cylinder 841 stationary to prevent multiple rivets from appearing in the feeding slot 832.

[0035] Furthermore, the feeding component 800 preferably includes a second photoelectric switch 860 mounted on the guide rail 820 for detecting rivets within the guide rail 820. The second photoelectric switch 860 is communicatively connected to the control component 600. Preferably, the second photoelectric switch 860 is mounted on the guide rail 820 near the vibratory feeder 810. When the second photoelectric switch 860 does not detect any rivets, it indicates that there is still space to place rivets in the section from the guide rail 820 to the feeding seat 830. The control component 600 will then continuously start the vibratory feeder 810 to continue conveying the rivets along the guide rail 820. If the second photoelectric switch 860 detects any rivets, it indicates that a certain amount of rivets has accumulated in the guide rail 820. At this time, the control component 600 will pause the operation of the vibratory feeder 810 to prevent excessive rivets in the guide rail 820 from causing blockage, ensuring a smooth and efficient feeding process.

[0036] Furthermore, the multi-hole bracket riveting machine of this utility model preferably includes an illumination component 900 mounted on the connecting frame 310 and positioned next to the visual recognition component 400. The illumination component 900 is communicatively connected to the control component 600. The illumination component 900 can be an LED ring light, a point light source, etc., and its main function is to provide sufficient light during the riveting process to ensure that the visual recognition component 400 can clearly acquire the image information of the rivet holes on the multi-hole bracket.

[0037] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
