Abstract
Description
Technical Field
[0001] This utility model relates to the field of riveting inspection, and in particular to an automatic rivet feeding mechanism used in rivet processing. Background Technology
[0002] A rivet is a nail-shaped object used to connect two parts (or components) with through holes and caps at one end. In riveting, the parts are joined by their own deformation or interference fit. For the processing of plate-type housing rivets, manual or robotic loading is still used after riveting. Given the increasing difficulty in recruiting workers and rising costs for enterprises, this paper proposes an automatic in-mold feeding mechanism for rivets to reduce labor or production costs and improve product quality. Utility Model Content

[0006] Preferably, the crossbar is disposed on the upper end of the mounting platform, one end of the slider is disposed inside the groove on one side of the crossbar, and the other end of the slider is disposed inside the groove on one side of the transmission rod.
[0007] Preferably, the mounting platform has an inner top at its upper end, and several first telescopic cylinders are arranged around the upper end of the mounting platform. A first support column is arranged at the upper end of the first telescopic cylinder, and a top plate is arranged at the upper end of the first support column. A hydraulic rod is arranged at the upper end of the top plate, and an upper die punch is arranged at the lower end of the top plate. A downward pressing detection mechanism is arranged at the lower end of the upper die punch. The top plate is compressed by the hydraulic rod at the top, thereby compressing the lower end parts and the upper die punch. The upper die punch and the downward pressing detection mechanism at the lower end are used for corresponding detection.

[0010] Preferably, an organic template is provided at the upper end of the support block, and rivets are evenly provided at the upper end of the organic template.
[0011] Preferably, the mounting platform is provided with several feet at its lower end.
[0012] Preferably, the micro switch is located on one side inside the mounting platform.
[0013] The beneficial effects of this utility model are as follows:
[0014] This utility model provides an automatic feeding mechanism for rivet molds. Four rotary motors are started to drive the turntable, the rotating shaft and the transmission rod to rotate respectively. The transmission rod drives the upper support plate to move. At the same time, the upper mold plate moves to a certain extent to perform the next rivet detection or processing, further improving the automation of feeding.
[0015] This system automatically detects and determines if any rivets are missing by installing a microswitch inside the mounting platform. When the mold closes, the upper die punch and inner ejector compress the rivet, forming a circuit. This compression of the bottom structure triggers the ejector rod, which in turn triggers the microswitch, sending a signal to proceed with the next side's inspection. Therefore, this mold design for rivet missing detection replaces manual visual inspection, reducing operator fatigue, lowering labor costs, and improving product inspection rate and quality. A feeding mechanism is installed at the lower end of the machine template. After inspection is completed... Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4 An automatic rivet feeding mechanism includes a mounting platform 1, with a plurality of mounting slots 10 symmetrically arranged on the upper end of the mounting platform 1. A feeding mechanism 2 is disposed inside the mounting slots 10. (Refer to...) Figures 3-4 The feeding mechanism 2 includes a rotary motor 201, a fixed shaft 202, a driving wheel 203, a driven wheel 204, a turntable 205, a transmission rod 206, a rotating shaft 207, a crossbar 208, a connecting block 209, a support plate 210, and a slider 211. The rotary motor 201 is located on one side of the mounting groove 10, and the driving wheel 203 is located on the same side. The driven wheel 204 is meshed with one side of the driving wheel 203. The fixed shaft 202 is located on one side of the driven wheel 204, and the other end of the fixed shaft 202 is fixedly connected to one side of the mounting groove 10. The other side of the driven wheel 204... A turntable 205 is provided, with a rotating shaft 207 on one side of the turntable 205. A transmission rod 206 is attached to the outer side of one end of the rotating shaft 207, and a connecting block 209 is attached to one side of one end of the transmission rod 206. A support plate 210 is attached to the upper end of the connecting block 209. When the rotary motor 201 is started, it drives the drive wheel 203 to rotate. The drive wheel 203 drives the driven wheel 204 on one side to rotate, and the driven wheel 204 drives the turntable 205 on one side to rotate. The rotating shaft 207 on the outer side of the turntable 205 drives the transmission rod 206 to rotate, and the transmission rod 206 drives the upper support plate 210 to move. That is, when four rotary motors are started, they drive the turntable, rotating shaft, and transmission rod to rotate respectively. The transmission rod drives the upper support plate to move, and at the same time, the upper template is moved to a certain extent for the next rivet inspection or processing, further improving the automation of material feeding.
[0023] Reference Figures 3-4A crossbar 208 is set on the upper end of the mounting platform 1. One end of the slider 211 is set inside the groove on one side of the crossbar 208, and the other end of the slider 211 is set inside the groove on one side of the transmission rod 206. When moving, the slider 211 inside the crossbar 208 and the transmission rod 206 will move. The transmission rod 206 remains vertical. When the support plate 210 is about to reach the highest point, it will lift the upper end of the machine template 9 and move it in a direction with the support plate 210. With the movement of the support plate 210, it will be placed on the support block 8, so as to achieve the purpose of the machine template 9 moving on the support block 8. A second cylinder 7 is set on the upper end of the mounting platform 1. A second pillar 6 is set on the upper end of the second cylinder 7. A support block 8 is set on the upper end of the second pillar 6. The support block 8 is used to support the machine template 9. The machine template 9 is set on the upper end of the support block 8. Rivets 13 are evenly arranged on the upper end of the machine template 9. The rivets 13 in the middle are set between the upper die punch 14 and the inner top 15.
[0024] In addition, a rivet missing detection is set in the mold. An inner top 15 is set at the upper end of the mounting platform 1. Four first telescopic cylinders 5 are also set around the upper end of the mounting platform 1. A first support column 4 is set at the upper end of the first telescopic cylinder 5. A top plate 11 is set at the upper end of the first support column 4. A hydraulic rod 12 is set at the upper end of the top plate 11. An upper mold punch 14 is set at the lower end of the top plate 11. A downward pressing detection mechanism is set at the lower end of the upper mold punch 14. The top plate 11 is compressed by the top hydraulic rod 12, which in turn compresses the lower end parts and the upper mold punch 14. The upper mold punch 14 and the lower downward pressing detection mechanism are used for corresponding detection.
[0025] Reference Figure 2 The detection mechanism includes a partition 16, which is located at the lower end of the inner top 15. A spring 17 is installed at the lower end of the partition 16, and a push rod 18 is installed at the lower end of the partition 16. A micro switch 19 is installed at the lower end of the push rod 18. When the inner top 15 presses the partition 16 downward, the partition 16 compresses the spring 17 downward, and the partition 16 moves downward. The push rod 18 installed at the lower end of the partition 16 touches the micro switch 19, completing the closed circuit. The micro switch 19 is electrically connected to the rotary motor 201 and the hydraulic rod 12. Several feet 3 are provided at the lower end of the mounting platform 1 to fix the mounting platform 1. The micro switch 19 is located on one side inside the mounting platform 1.
[0026] The detection principle is as follows: When the mold is closed, the upper mold punch 14 presses the rivet 13 onto the machine template 9. The rivet 13 presses the inner ejector 15 down, the partition 16 compresses the spring 17, and the partition 16 drives the ejector rod 18 to contact the micro switch 19. The micro switch 19 sends a signal to the hydraulic rod 12. If there is a rivet 13, it is considered OK. The hydraulic rod 12 retracts, the spring 17 returns to its original position, the feeding mechanism 2 rotates, and the support plate 210 moves the machine template to detect the next rivet 13. If a rivet 13 is missing when the mold is closed, the inner ejector 15 does not compress the spring 17, so the ejector rod 18 does not contact the micro switch 19, and no signal is sent to the hydraulic rod 12. The rivet 13 is considered NG, the hydraulic rod 12 stops running, and the rivet 13 missing inspection is completed.
[0027] The circuit switching and signal transmission control principles described above are existing technologies and will not be elaborated upon here.
[0028] The aforementioned device is also a rivet device with functions of missing rivet detection and automatic feeding.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
