[0002] At present, in the assembly and production process of electronic products, the process of cutting and loading related components is an important part of providing the working efficiency of automated equipment, because the assembly accuracy and process requirements of many electronic components are very high, such as shrapnel.

[0003] At present, the feeding process of shrapnel includes: material loading, feeding, transferring, cutting and lowering of waste belt and other processes, among which the connection between loading and feeding, as well as lowering of waste belt are all manually operated, which not only affects the work efficiency but also has high labor costs; at the same time, since the tail of the material belt has no power to drive the lower waste belt, the material belt between the driving area of ​​the feeding power and the lower waste belt area cannot continue to be transported downward, resulting in the material belt not being fully utilized and wasted; in addition, when the material belt is used up and the material belt reel is replaced, the door is opened and the machine is stopped to remove the tail waste and residual material belt, which greatly reduces the utilization rate of the automation equipment.

[0006] The feeding mechanism, the material transfer and cutting mechanism and the tail material discharge and waste cutting mechanism are all provided with mutually connected material channels, the material channel on the feeding mechanism is at least one more than the material channels on the material transfer and cutting mechanism and the tail material discharge and waste cutting mechanism, and the material feeding path of the feeding mechanism is the same as the number of the material channels on the feeding mechanism and is arranged accordingly;

[0007] The feeding mechanism and the feeding mechanism are both slidably mounted on the machine body, and the sliding directions of the feeding mechanism and the feeding mechanism are perpendicular to the setting direction of the material channel.

[0008] As an improvement, the feeding mechanism includes a sliding seat driven by a power device and slidably mounted on the machine body. A plurality of material channels are provided on the sliding seat, and a first material pushing wheel driven by a first power component is rotatably mounted on the sliding seat at a position corresponding to each material channel.

[0009] As a further improvement, an installation seat that slides vertically and is driven by a first linear driving element is provided on the sliding seat. The first power component and the first material pushing wheel are arranged on the installation seat.

[0010] As an improvement, the feeding mechanism includes a plurality of guide plates provided in one-to-one correspondence with the plurality of material channels on the feeding mechanism. Each guide plate is provided with a guide groove; it also includes a plurality of material trays and a plurality of release paper recovery trays provided on the machine body. The release paper recovery trays are driven by a second power component;

[0011] A sliding table is slidably mounted between all the guide plates and the machine body. The sliding table is driven by a second linear driving element.

[0012] As an improvement, the material transfer and cutting mechanism and the tail material discharging and waste cutting mechanism share the same power mechanism.

[0013] As a further improvement, the material transfer and cutting mechanism includes a support seat provided with the material channel.

When reaching the cutting station, the material tape is cut, and electronic components (such as shrapnel) on it are separated. While the second material pusher wheel is working, the third material pusher wheel on the waste tailstock export mechanism also works synchronously and sends the side waste material tape formed after cutting to the shearing mechanism.

[0021] In summary, by adopting this material supply and cutting device, the full-process automation work from loading to unloading is realized, and there is no need to stop the machine to replace the material tray during the working process, which greatly improves the working efficiency and the equipment operation rate, and effectively reduces the labor cost. At the same time, the feeding power connection between each process is good, which ensures the complete use of the material tape, improves the utilization rate of the material tape, and solves the problem of material tape waste.

Specific embodiments

[0033] Next, embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and therefore are only examples and cannot be used to limit the protection scope of the present invention.

[0034] For the convenience of description, in this embodiment, the elastic strip 6 is taken as an example for elaboration. Process holes 601 are provided on one side and / or both sides of the elastic strip 6 (see Figure 2 ), of course, the present solution is not limited to the feeding, loading and cutting of the elastic strip 6, and can also be applied to the feeding, loading and cutting of other materials.

[0035] As Figure 1As shown, a material supply and cutting device comprises a machine body (not shown in the figure), on which a feeding mechanism 1 is provided, a feeding mechanism 2 is connected to the machine body located upstream of the feeding mechanism 1, a material transfer and cutting mechanism 3 is connected to the machine body located downstream of the feeding mechanism 1, and a tail material discharge and waste cutting mechanism 4 is connected to the machine body located downstream of the material transfer and cutting mechanism 3, and the material transfer and cutting mechanism 3 and the tail material discharge and waste cutting mechanism 4 share the same power mechanism 7; the feeding mechanism 1, the material transfer and cutting mechanism 3 and the tail material discharge and waste cutting mechanism 4 are all provided with material channels 5 that are interconnected, and the The material channel 5 on the feeding mechanism 1 has at least one more material channel 5 than the material channel 5 on the material transfer and cutting mechanism 3 and the tail material discharge and waste cutting mechanism 4. The feeding path of the feeding mechanism 2 is the same as the number of the material channels 5 on the feeding mechanism 1 and is set one by one. At the same time, the feeding mechanism 2 and the feeding mechanism 1 are both slidably mounted on the machine body, and the sliding direction of the feeding mechanism 2 and the feeding mechanism 1 is set in a perpendicular relationship to the setting direction of the material channel 5. The feeding mechanism 1, the material transfer and cutting mechanism 3 and the tail material discharge and waste cutting mechanism 4 located on both sides of the material channel 5 are provided with sensors 8 for detecting the presence or absence of the spring sheet material belt 6. Therefore, through the above-mentioned connected mechanisms, not only the full process automation between loading and unloading is realized, but also there is no need to stop the machine to replace the material tray during the working process, which greatly improves the work efficiency and equipment utilization rate, and effectively reduces the labor cost; at the same time, the feeding power connection between each process is good, which ensures the complete use of the material belt, improves the utilization rate of the material belt, and solves the problem of material belt waste.

[0036] In this embodiment, the power mechanism 7 is a belt transmission mechanism; the material transfer and cutting mechanism 3 and the tail material discharge and waste cutting mechanism 4 are both provided with a material channel 5 for feeding, the feeding mechanism 1 is provided with two material channels 5 for feeding, and the feeding mechanism 2 is provided with two feeding paths, so that through the sliding of the feeding mechanism 2 and the feeding mechanism 1, one of the feeding paths on the feeding mechanism 2 and one of the material channels 5 on the feeding mechanism 1 are connected and communicated with the material channel 5 on the material transfer and cutting mechanism 3, and switched during continuous work, laying a foundation for improving the equipment utilization rate and non-stop operation. Of course, in order to improve work efficiency, the material transfer and cutting mechanism 3 and the tail material discharge and waste cutting mechanism 4 are both provided with two or n material channels 5, and correspondingly, the feeding mechanism 1 is provided with three or n+1 material channels 5, the feeding mechanism 2 is provided with three or n+1 feeding paths, and the like (n is greater than 2).

[0037] like Figures 2 to 4As shown together, the feeding mechanism 1 includes a slide base 101 driven by a power device 107 and slidably mounted on the machine body. A plurality of parallel material channels 5 are provided on the slide base 101. A first material shifting wheel 102 driven by a first power component 105 (such as a servo motor) is rotatably mounted on the slide base 101 at a position corresponding to each material channel 5. Teeth adapted to the process holes 601 are provided on the outer periphery of the first material shifting wheel 102. The first material shifting wheel 102 is located above the shrapnel tape 6. In this embodiment, the power device 107 is a lead screw and lead screw nut structure driven by a motor. The first power component drives two coaxially arranged first material shifting wheels 102. The two first material shifting wheels 102 are arranged in one-to-one correspondence with the process holes 601 on both sides of the shrapnel tape 6. The first material shifting wheel 102 has teeth adapted to the process holes 601, so as to synchronously drive the shrapnel tape 6 through the two first material shifting wheels 102, ensuring the synchronization of the feeding of both sides of the shrapnel tape 6 and avoiding the deviation of the shrapnel tape 6 in the material channel 5, which may affect the feeding work.

[0038] An installation base 104 is vertically slidably provided on the slide base 101 and driven by a first linear drive element 103 (such as a cylinder, an oil cylinder, etc.). The first power component 105 and the first material shifting wheel 102 are arranged on the installation base 104. Thus, through the vertical sliding of the installation base 104, the first material shifting wheel 102 is driven to move vertically, which is not only conducive to effectively feeding the shrapnel tape 6 to the feeding area of the first material shifting wheel 102, but also convenient for adjustment when the shrapnel tape 6 cannot be normally conveyed. A protective cover 106 covering the first material shifting wheel 102 is also provided on the installation base 104. Since the first material shifting wheel 102 is located above the shrapnel tape 6 and is exposed, the protective cover 106 ensures the safety of the work.

[0039] As Figure 1 As shown, the feeding mechanism 2 includes a plurality of guide plates 201 arranged in one-to-one correspondence with the plurality of material channels 5 on the feeding mechanism 1. A guide groove 202 for restraining, positioning and guiding the shrapnel tape 6 is provided on each guide plate 201. It also includes a plurality of material trays 203 and a plurality of release paper recovery trays 204 arranged on the machine body. The material trays 203 and the release paper recovery trays 204 are arranged outside the machine body to facilitate the replacement of the shrapnel tape 6 on the material trays 203 after it is used up. The release paper recovery tray 204 is driven by a second power component 205 (such as a servo motor). A slide table 206 is slidably mounted between all the guide plates 201 and the machine body. The slide table 206 is driven by a second linear drive element 207 (such as a cylinder, an oil cylinder, etc.).

[0040] As Figures 5 to 7As shown together, the material shifting and cutting mechanism 3 includes a support seat 301 provided with a material channel 5, on which two coaxially arranged second material shifting wheels 302 (specifically installed on the power output shaft of the belt transmission mechanism) driven by a power mechanism 7 are rotatably installed, and the second material shifting wheels 302 are located below the spring sheet material belt 6 and have the same structure as the first material shifting wheel 102; a cutting station is provided at the end of the support seat 301, and the cutting station is provided with a fixed knife body fixedly installed on the support seat 301, and the fixed knife body is located above the spring sheet material belt 6, and a movable knife body is provided on the support seat 301 corresponding to the position of the fixed knife body and located below the spring sheet material belt 6, and the movable knife body is driven by a cylinder 304, and the related structures of the fixed knife body and the movable knife body are conventional structures in this field, so they are not shown in detail in the accompanying drawings.

[0041] like Figure 8 and Figure 9 As shown together, the tail material discharge and waste cutting mechanism 4 includes a discharge seat 401, on which two coaxially arranged third material paddle wheels 402 (specifically installed on the power output shaft of the belt transmission mechanism) driven by the power mechanism 7 are rotatably installed, and the third material paddle wheels 402 are located below the spring sheet material belt 6 and have the same structure as the first material paddle wheels 102; a waste channel 403 is provided on the discharge seat 401, and a shearing mechanism is provided on the discharge seat 401 at the end of the waste channel 403. The shearing mechanism includes a fixed knife 404 arranged on the discharge seat 401 and arranged on one side of the waste channel 403, and a knife seat 405 driven by a third linear driving element 409 (such as: cylinder, oil cylinder, etc.) is provided on the discharge seat 401 at a position corresponding to the fixed knife 404, and a movable knife 406 is provided on the knife seat 405, and the movable knife 406 is arranged staggered with the fixed knife 404.

[0042] The tail material lead-out and waste cutting mechanism 4 and the material transfer and cutting mechanism 3 driven synchronously by the above-mentioned power mechanism 7 not only ensure the orderly transportation of the spring sheet material strip 6 between the two, but also ensure that the end part of the spring sheet material strip 6 is effectively driven to the tail material lead-out and waste cutting mechanism 4. Compared with the waste at the end of the traditional spring sheet material strip 6, there is no situation where the tail material strip cannot be utilized, thereby reducing the production cost (material strip cost); at the same time, there is no need to manually disassemble the spring sheet material strip 6 after cutting.

[0043] In this embodiment, both the tool holder 405 and the discharge seat 401 are provided with waste discharge belt holes 407 that communicate with each other. A discharge pipe 408 is also communicated with the position corresponding to the waste discharge belt holes 407, and the discharge pipe 408 is arranged on the discharge seat 401. A guiding and limiting plate 303 is installed on the support seat 301, and the guiding and limiting plate 303 extends into the waste channel 403, and the waste belt (i.e., the edge of the elastic sheet strip 6 with the process holes 601) is located on both sides of the guiding and limiting plate 303. There are two arc-shaped plates on the discharge seat 401, and there is a spacing between the two arc-shaped plates. The guiding and limiting plate 303 extends into this spacing, and there is also a gap between the two arc-shaped plates and the discharge seat 401, and this gap forms the waste channel 403 through which the actual waste belt passes. Thus, through the guiding and limiting plate 303, the waste belts formed on both sides after cutting are orderly conveyed in the waste channel 403 to ensure the normal operation of the subsequent shearing mechanism.

[0044] To facilitate the understanding of this solution, the working principle of a material supply and cutting device provided by the present utility model is as follows:

[0045] First, install multiple material trays 203 in place. Then, introduce one end of the elastic sheet strip 6 on one of the material trays 203 into the material channel 5 on the feeding mechanism 1 and determine the feeding origin at the position of the first feeding wheel 102. Then, the release paper recovery tray 204 is driven to recover the release paper on the elastic sheet strip 6, and at the same time, drive the material tray 203 to rotate and gradually release the strip into the guide groove 202. During the above process, the first feeding wheel 102 drives the elastic sheet strip 6 (the elastic sheet strip 6 after peeling off the release paper) to be conveyed towards the material transfer and cutting mechanism 3. Then, the second feeding wheel 302 drives the elastic sheet strip 6 to continue to be conveyed downstream. When reaching the cutting station, cut the elastic sheet strip 6 and separate the elastic sheets thereon. While the second feeding wheel 302 is working, the third feeding wheel 402 on the tail material export and waste cutting mechanism 4 also works synchronously and conveys the side waste belt formed after cutting to the shearing mechanism. Then, the shearing mechanism cuts the side waste belt and discharges it through the waste discharge belt holes 407 and the discharge pipe 408 for recycling. During the above work, when a feeding failure occurs, the mounting seat 104 driven by the first linear driving element 103 and the first feeding wheel 102 move upward for subsequent processing; the sensor 8 also synchronously detects the elastic sheet strip 6. If the elastic sheet strip 6 on the material tray 203 is used up, the feeding mechanism 2 and the feeding mechanism 1 slide, and connect another material tray 203, the guide groove 202 and the material channel 5 on the feeding mechanism 1 with the material channel 5 on the material transfer and cutting mechanism 3. Then, replace the material tray 203 with the elastic sheet strip 6 and perform continuous flow operation according to the above process.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
