The process of producing a button is basically: placing the parts to be pressed together - pressing with a hand wheel machine - producing the finished product. This method has low production efficiency and low yield rate.

[0003] Based on the problem of manual production, there are some button assembly machines in the prior art, which use mechanical devices to replace manual production to improve production efficiency. The current button assembly machine generally includes two groups of feeding devices, one for conveying the upper workpiece of the button, and the other for conveying the lower workpiece of the button. The upper and lower workpieces of the button are conveyed to a mold seat, and a punching device is used to punch to form a button product. The problem of the existing button machine is that: since the upper workpiece is to be placed on the lower workpiece, there must be a time difference between the upper and lower workpieces being sent to the mold seat, that is, the upper workpiece must wait for a period of time to allow the lower workpiece to be placed in the mold seat first when feeding. At the same time, the punching device must wait for the upper workpiece to be placed on the lower workpiece before punching. This results in that the time consumed by the button assembly machine for feeding and punching is actually not long during production, and most of the time is consumed in waiting for the workpiece to be in place, resulting in the overall processing speed of the existing button assembly machine not being able to be improved, and the production efficiency is still limited.

DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] This embodiment discloses a high-speed button assembly machine. Figure 1-7 As shown, it includes a frame 1, a punch assembly 2, a workbench 3 located below the punch assembly 2, and a first feeding device 4 and a second feeding device 42 for conveying workpieces to the workbench 3, wherein the first feeding device 4 conveys the upper workpiece of the button, and the second feeding device 42 conveys the lower workpiece of the button, and both convey the workpiece to the workbench 3, and then the punch assembly 2 is used to punch the button to form a finished product. In this embodiment, the first feeding device 4 includes a feeding platform 5 and a movable feeding platform 6, and the feeding platform 6 has a first station and a second station. Figure 7 At the first workstation, the feeding platform 6 cooperates with the feeding platform 5, that is, the feeding platform 6 is opposite to the outlet of the feeding platform 5, and is used to receive the workpiece on the feeding platform 5; wherein, the feeding platform 5 is connected to an external vibration plate, and the vibration plate continuously transports the upper workpiece of the button to the feeding platform 5, and the feeding platform 5 then transports the upper workpiece to the feeding platform 6.

[0029] For further reference Figure 3-4At the second station, the feeding platform 6 moves to the bottom of the punch assembly 2. The punch assembly 2 moves downward to pick up the workpiece onto the punch assembly 2. Therefore, at the second station, the feeding platform 6 is used to transfer the workpiece to the punch assembly 2. At the same time, a travel plate 7 is provided on the feeding platform 6, and a travel wheel 8 is provided on the punch assembly 2. When the punch assembly 2 punches downward, the travel wheel 8 abuts against the travel plate 7 and drives the feeding platform 6 to move from the second station to the first station. It should be noted that the upper half of the stroke of the stroke plate 7 is a straight line, and the lower half of the stroke is an inclined surface. Therefore, when the punch assembly 2 just starts to move downward, the feeding platform 6 will not move, so that the upper workpiece can just be received by the punch assembly 2. After the upper workpiece is inserted into the punch assembly 2, the punch assembly 2 continues to move downward. At this time, the lower half of the stroke takes effect, so that the feeding platform 6 is pushed to one side, so that the punch assembly 2 can carry the upper workpiece together with the lower workpiece in the workbench 3 for stamping. The execution action of the entire mechanism is ingenious, and the placement of the upper workpiece and the stamping action are basically performed simultaneously, which greatly shortens the processing time and improves production efficiency.

[0030] For further information, please refer to Figure 7-9 , a material blocking mechanism 9 is arranged on the frame 1, and the material blocking mechanism 9 includes a sliding table 901, and a first blocking piece 10 and a second blocking piece 11 are arranged on the sliding table 901, and the first blocking piece 10 and the second blocking piece 11 are extended and arranged on the feeding channel of the feeding platform 5, and the first blocking piece 10 and the second blocking piece 11 are arranged in a staggered manner, and a gap 12 for a workpiece to enter is left between the two. At the same time, the sliding table 901 has a material blocking station A and a material blocking station B, and a guide rail 13 is arranged on the feeding platform 6. A guide wheel 1301 that abuts against the guide rail 13 is arranged on the sliding table 901, and the sliding table 901 can be driven to slide back and forth between the material blocking station A and the material blocking station B through the cooperation of the guide rail 13 and the guide wheel 1301. Through the above structure, when the feeding platform 6 is at the first station, the sliding table 901 is at the blocking station A. At this time, the first baffle 10 blocks the subsequent workpiece, and the second baffle 11 moves away, so that the workpiece in the gap 12 can move to the feeding platform 6. When the feeding platform 6 receives the workpiece and moves to the second station, due to the cooperation of the guide rail 13 and the guide wheel 1301, the sliding table 901 moves to the blocking station B. At this time, the first baffle 10 moves away, and the second baffle 11 blocks the channel, so that the workpiece smoothly enters the gap to prepare for subsequent feeding. In short, at the blocking station A, the first baffle 10 blocks the workpiece on the feeding platform 5, and at the blocking station B, the second baffle 11 blocks the workpiece on the feeding platform 5.

[0031] Furthermore, a blowing hole 1001 is provided on the first baffle 10, and the blowing direction of the blowing hole 1001 is arranged toward the second baffle 11. On the basis of the above structure, in order to smoothly load the workpiece from the feeding platform Figure 5Move to the feeding platform 6 , a blowing hole 1001 is provided on the first baffle 10 , and the blowing hole 1001 is connected to an external air source, which blows the workpiece in the gap 12 onto the feeding platform 6 by blowing air.

[0032] Furthermore, a limit swing rod 14 is hingedly provided on the feeding platform 6, and a torsion spring is provided on the limit swing rod 14. The limit swing rod 14 is used to limit the workpiece on the feeding platform 6. Figure 6 , Figure 6 The hinged end 14a and the free end 14b of the limit swing rod 14 are marked, and the free end 14b of the swing rod extends from the back of the travel plate 7 to the front of the feeding platform 6; Figure 8 When the feeding platform 6 is at the first station, the limit swing rod 14 blocks the outlet of the feeding platform 6. When the upper workpiece is blown into the feeding platform 6, the limit swing rod 14 can just block the upper workpiece to prevent the upper workpiece from falling out. Figure 6 When the feeding platform 6 moves from the second station to the first station, since the upper workpiece has been stuck in the punch assembly 2 at this time, the upper workpiece will push the limit swing rod 14 to one side, so that the upper workpiece can be smoothly moved out of the feeding platform 6, and the feeding platform 6 returns to the first station to prepare for the next material reception.

[0033] Furthermore, a driving cylinder 15 is provided on the frame 1, and the output rod of the driving cylinder 15 is connected to the feeding platform 6 and drives the feeding platform 6 to slide, and the driving cylinder 15 is connected to the external air source through the electromagnetic valve. Preferably, the present embodiment uses a cylinder to control the movement of the feeding platform 6; since the running speed of the whole combined machine is relatively fast, and the punch assembly 2 has a relatively large punching force, and the punch assembly 2 in the present mechanism will drive the feeding platform 6 to move through the cooperation of the travel wheel 8 and the travel plate 7 during the punching, this results in the movement of the feeding platform 6 being substantially controlled by two mechanisms (travel plate and travel wheel, driving cylinder), and the fast running speed makes it difficult to ensure that the two mechanisms are completely synchronized in the movement of the feeding platform 6, and there may be interference, and the advantage of using pneumatic drive is that the gas is highly compressible, even if the action of the driving cylinder 15 is partially delayed compared with the travel wheel 8 and the travel plate 7, it can be buffered due to the self-compression of the gas, and will not cause damage to the device.

[0034] For further information, please refer to Figure 3-4The punch assembly 2 includes a retractable punch rod 201, and the end of the punch rod 201 is provided with a receiving hole 202 (dashed line part in the figure), and the receiving hole 202 is plugged with the workpiece. Through the above structure, when the feeding platform 6 is in the second station, the punch assembly 2 is pressed down, so that the workpiece is inserted into the receiving hole 202 of the punch rod 201, and then the punch rod 201 continues to descend. At this time, the travel wheel 8 just reaches the lower half of the travel plate 7. In order not to damage the feeding platform 6, the punch rod 201 will shrink inward until the feeding platform 6 is removed. The punch rod 201 enters the workbench 3, and the workbench 3 just has the lower workpiece of the button delivered by the second feeding device 42, so that the combination of the upper and lower workpieces of the button is completed. And the upper workpiece is delivered to the workbench and the stamping is basically completed synchronously, with high speed and high efficiency.

[0035] Further, see Figure 4 The feeding platform 5 includes a bottom plate 501 and an adjustable upper plate 502. A feeding channel for the workpiece to pass through is reserved between the bottom plate 501 and the upper plate 502. A guide slit is provided on the upper plate 502, and the workpiece moves along the guide slit. The upper plate 502 is connected to the bottom plate 501 by bolts. When adjustment is required, only a gasket needs to be added between the bottom plate 501 and the upper plate 502. In this way, it can be adapted according to the thickness of different upper workpieces of different buttons, thereby increasing versatility. At the same time, since there is a protrusion on the upper workpiece, a guide slit is provided for the protrusion to enter, thereby ensuring smooth transportation of the workpiece.

[0036] Further, see Figure 5 A detection mechanism 16 is arranged on the feeding platform 6, and the detection mechanism 16 includes a controller and a detection module 1601. The detection module 1601 is arranged on both sides, and the workpiece is located in the middle position. The detection module 1601 can use an infrared detection module. The detection mechanism 16 is used to detect the workpiece on the feeding platform 6, and send instructions to the driving cylinder or an external alarm through the controller. After the workpiece is received at the first workstation, the driving cylinder 15 moves the feeding platform normally; when the workpiece is not detected, an alarm can be issued through the controller to remind nearby operators to check in time to prevent empty processing.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
