Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and specifically relates to a stamping part anti-scratch transportation device, a stamping part anti-scratch transportation method and a stamping system. Background Art

[0002] The stamping products of punch presses are generally divided into two forms: upper discharge and lower discharge. The upper discharge can usually be carried by a robot, and the lower discharge usually has a conveyor line at the bottom of the discharge end to output the stamped products. For high-speed punch presses, the punching speed is very fast. Before the next product arrives, the previous product must be transported out of the discharge end of the punch press. The conveying schemes currently used can generally be divided into two types: air conveying and belt conveying. However, these two conveying methods cannot prevent the product from directly contacting the conveying device, causing scratches on the product, seriously affecting product quality, and causing scrapping.

[0003] During the stamping process, consider setting up a carrier for loading products for protection. During the stamping process, the stamped products are first placed in the carrier and then transported through the conveying device. Traditional conveyors are mostly driven by independent motors, which can meet the requirements of low-speed transportation. If the conveyor is to be consistent with the timing of the high-speed punch press to achieve intermittent motion and transport the stamped parts processed by the punch press through the conveyor in time, the motor performance of the conveyor is very high, and multiple sensors such as encoders must be added. This type of conveyor line has a high failure rate and poor stability. Utility Model Content

[0048] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0049] If the utility model involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.) when describing, it is necessary to define the directions involved, such as "In order to clearly express the positions and directions described in the utility model, the end close to the operator is the proximal end, and the end far from the operator is the distal end." Or define it with the paper as a reference, with the depth direction of the refrigerator as a reference, etc. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, it does not need to be defined here.

[0050] In the prior art, for high-speed punching machines, the punching speed is very fast. Before the next product arrives, the previous product must be transported outside the discharge end of the punching machine. The currently used conveying solutions are generally divided into two types: air conveying and belt conveying. However, both of these conveying methods cannot prevent the product from directly contacting the conveying device, causing scratches on the product, seriously affecting product quality, and causing it to be scrapped.

[0051] During the stamping process, consider setting up a carrier for loading products for protection. During the stamping process, the stamped products are first placed in the carrier and then transported through the conveying device. Traditional conveyors are mostly driven by independent motors, which can meet the requirements of low-speed transportation. If the conveyor is to be consistent with the timing of the high-speed punch press, realize intermittent motion, and promptly transport the stamped parts processed by the punch press, the motor performance requirements are very high, and multiple sensors such as encoders must be added. This type of conveyor line has a high failure rate and poor stability.

[0052] In order to solve the above problems in the prior art, the utility model provides a stamping part anti-scratch conveying device, such as Figure 1-10 As shown, an anti-scratch transportation device for stamping parts provided by an embodiment of the utility model includes a carrier conveying unit, and the carrier conveying unit includes a slideway assembly 1, a push rod assembly 2, and a power assembly 3.

[0053] The slide assembly 1 includes a slide base plate 11, which is used to carry one or more carriers 6. The carriers 6 are used to accommodate stamping parts 7 and block direct contact between the stamping parts 7 and external objects. A material receiving station is provided on the slide base plate 11, and the material receiving station is arranged directly below the discharge port of the stamping equipment. The carrier at the material receiving station can receive the stamping parts dropped from the discharge port.

[0054] Furthermore, the push rod assembly 2 includes a push rod 21, a linear guide rail 22 and a baffle 23. The push rod 21 is at least partially arranged above the slide base plate and can move back and forth between the first station and the second station along the linear guide rail 22. The baffle 23 is connected to the push rod 21. When the push rod 21 moves from the first station to the second station, the push rod 21 can drive the carrier 6 on the slide base plate 11 to move along the first direction, and at the same time, the baffle 23 can prevent the carrier 6 from moving to the slide base plate 11 along the second direction. When the push rod 21 is located at the first station, the baffle 23 allows the carrier 6 to move to the slide base plate along the second direction, and the first direction intersects with the second direction.

[0055] The power assembly 3 includes a driving wheel 31, a driven wheel 32, a cam 33, a cam follower, and a follower plate 34. The driving wheel 31 is in transmission cooperation with the cam 33 through the driven wheel 32. The cam follower is arranged on the follower plate 34 and is in close contact with the cam 33. The follower plate is in transmission cooperation with the push rod 21. The driving wheel 31 is powered by the main shaft of the stamping equipment 8. When the driving wheel 31 is driven to pivot, it can drive the cam 33 to pivot to drive the follower plate 34 to move, thereby making the push rod 21 move back and forth between the first station and the second station along the linear guide rail 22.

[0056] In this configuration, the main shaft of the stamping equipment 8 provides power for the driving wheel 31 and drives the cam 33 to pivot through the driven wheel 32, drives the follower plate 34 to move through the cam 33, and then drives the push rod 21 to move back and forth between the first station and the second station through the transmission cooperation between the follower plate 34 and the push rod 21, driving the carrier 6 on the slide bottom plate 11 to move to the material receiving station along the first direction. The carrier 6 at the material receiving station can receive the stamping parts 7 dropped from the discharge port, and then move to the outside of the slide bottom plate 11 along the first direction. The main shaft of the stamping equipment 8 has the same timing as the cam 33, which can make the timing of the stamping of the lever 21 and the stamping equipment consistent, so that the stamping parts processed by the stamping equipment can be transported away in time, thereby improving the stability of the anti-scratch conveying device for stamping parts.

[0057] refer to Figure 4 As shown, the slide assembly 1 also includes one or more of a carrier in-place sensor 12 , a carrier positioning assembly, and a discharge port sensor 13 .

[0058] Specifically, the carrier in-position sensor 12 is arranged on the slide bottom plate 11, and is used to sense that the empty carrier 6 moves along the second direction to a predetermined position on the slide bottom plate 11. The function of the carrier in-position sensor 12 is mainly to control the number of carriers 6 thrown onto the slide bottom plate 11 from the second direction, and when the carrier 6 is placed at the predetermined position, stop throwing the carrier 6 onto the slide bottom plate 11. Such an arrangement can improve the degree of automation of throwing the empty carrier 6 onto the slide bottom plate 11.

[0059] The carrier positioning assembly includes a carrier front positioning assembly 14 and a carrier rear positioning assembly 15. The carrier front positioning assembly 14 is arranged at the discharge end of the slideway bottom plate 11 where the carrier 6 is output, and the carrier rear positioning assembly 15 is arranged on the slideway bottom plate 11 and is located between the two ends of the slideway bottom plate 11. The carrier front positioning assembly 14 and the carrier rear positioning assembly 15 cooperate to define the position of the carrier 6 located therebetween, thereby preventing the carrier 6 equipped with the stamping part 7 from shaking on the slideway bottom plate 11, causing the stamping part 7 to slip out of the carrier 6 and cause scratches.

[0060] The discharge port sensor 13 is disposed at the material receiving station and is used to sense that the empty carrier 6 has arrived at the material receiving station, so as to control the discharge port to discharge the stamping parts 7 .

[0061] Furthermore, the carrier front positioning assembly 14 includes at least two limit members arranged relatively along the second direction, and a accommodating space is formed between the two limit members. When the push rod moves from the first station to the second station, the push rod 21 moves the multiple carriers 6 on the slide base plate 11, and makes some of the carriers 6 abut against the limit members to adjust the accommodating space to become larger, so that the carrier 6 abutting against the limit members passes through the accommodating space.

[0062] refer to Figure 5-6 As shown, in this embodiment, the two relatively arranged limiting members include a first limiting member 141 and a second limiting member 142, and the first limiting member 141 and the second limiting member 142 are relatively arranged along the second direction. When the push rod 21 moves the multiple carriers 6 on the slideway bottom plate 11, some of the carriers 6 abut against the first limiting member 141 and the second limiting member 142, so that the accommodation space between the first limiting member 141 and the second limiting member 142 becomes larger, so that the carriers 6 abutting against the first limiting member 141 and the second limiting member 142 pass through the accommodation space.

[0063] It can be understood that such a configuration can control the number of carriers passing through the discharge end through the carrier front positioning component 14, and make these carriers 6 pass through the accommodating space in an orderly manner.

[0064] In this embodiment, the carrier front positioning assembly 14 further includes a mounting seat, a plurality of first stoppers 141 and a plurality of second stoppers 142, a first mounting plate, and a second mounting plate. The plurality of first stoppers 141 are arranged on the first mounting plate, the mounting seat has a first support wall 143 and a second support wall 144 arranged opposite to each other along the second direction, and mounting columns are arranged at both ends of the first mounting plate in the second direction, wherein the mounting column at one end is inserted into the first support wall 143 and can slide relative to the first support wall 143 in the second direction; the mounting column at the other end is inserted into the second support wall 144 and can slide relative to the second support wall 144 in the second direction. In the second direction, elastic members 146 are respectively arranged between the first mounting plate and the first support wall 143 and the second support wall 144, and the elastic member can usually be arranged as a compression spring, and the compression spring is sleeved on the mounting column.

[0065] Correspondingly, a plurality of second stoppers 142 are arranged on the second mounting plate, and the mounting seat has a third support wall 145 and a fourth support wall (not shown in the figure) arranged opposite to each other along the second direction, and mounting posts are arranged at both ends of the second mounting plate in the second direction, wherein the mounting post at one end is inserted into the third support wall 145 and can slide relative to the third support wall 145 in the second direction; and the mounting post at the other end is inserted into the fourth support wall and can slide relative to the second support wall in the second direction. In the second direction, elastic members are respectively arranged between the second mounting plate and the third support wall 145 and the fourth support wall, and the elastic members can generally be arranged as compression springs, and the compression springs are sleeved on the mounting posts.

[0066] With such a configuration, the abutment between the carrier 6 and the relatively arranged first limit member 141 and the second limit member 142 can enlarge the accommodating space between the first limit member 141 and the second limit member 142, and after the carrier abutting against the first limit member 141 and the second limit member 142 passes through the accommodating space, the accommodating space becomes smaller due to the action of the compression spring.

[0067] In this embodiment, the carrier front positioning assembly 14 includes a plurality of pairs of first limiting members 141 and second limiting members 142 arranged opposite to each other, so that each time the push rod 21 is moved from the first station to the second station, the discharging end can output a plurality of the carriers 6 at the same time.

[0068] In this embodiment, reference Figure 7As shown, the carrier rear positioning assembly 15 includes a pivot rod 152 and a support 151 arranged under the slide base plate. The first end of the pivot rod is pivotally connected to the support 151, and the second end is used to be clamped on the slide base plate 11. When the push rod 21 moves from the first station to the second station, the push rod 21 moves the multiple carriers 6 on the slide base plate 11, and makes some of the carriers 6 abut against the pivot rod 152 to drive the pivot rod 152 to pivot, so that some of the carriers 6 move toward the discharge end and are clamped with the pivot rod 152.

[0069] Specifically, the carrier rear positioning assembly 15 also includes an elastic member 153, one end of the elastic member 153 is connected between the two ends of the pivot rod 152, and the other end is fixedly connected to the bottom of the slide base plate 11. The slide base plate 11 is provided with a clamping groove for clamping the second end of the pivot rod 152. The pivot rod 152 can be clamped in the clamping groove through the elastic member 153, and the second end has a protruding portion protruding out of the clamping groove, and the protruding portion protrudes out of the upper surface of the slide base plate 11 and has a slope surface 1521. When the carrier 6 abuts against the pivot rod 152, the carrier 5 acts on the slope surface 1521 to help the pivot rod 152 to pivot.

[0070] With such arrangement, when the lever 21 moves the plurality of carriers 6 along the first direction, some of the carriers 6 can abut against the slope surface 1521 to pivot the pivot rod 152, thereby allowing the carriers 6 to pass over the pivot rod 152 and move along the first direction toward the discharge end of the slide bottom plate 11.

[0071] Further, refer to Figure 4 As best shown, the slide assembly 1 also includes two side panels 17 arranged opposite to each other along the second direction, and the two side panels 17 are connected to the two sides of the slide base plate 11 in the second direction. When the push rod 21 moves from the first station to the second station, the two side panels 17 prevent the carrier 6 from sliding out of the slide base plate 11 along the second direction.

[0072] In this embodiment, reference Figure 8-9As shown, the anti-scratch transport device for stamping parts also includes a transition transmission unit 4 and a lifting and conveying unit 5. The transition transmission unit 4 is arranged between the carrier conveying unit and the lifting and conveying unit 5, and is used to transport the carrier 6 carrying the stamping parts 7 output by the carrier conveying unit to the lifting and conveying unit 5. The lifting and conveying unit 5 includes two relatively arranged and closed-loop pin chains 51, a frame 52 for installing the pin chains, a sprocket 53 for driving the pin chains and a plurality of pallets 54. An entrance 521 and an exit 522 are formed on the frame 52, and the exit 522 is located above the entrance 521. The pallet 54 is connected between the two pin chains 51, and the pin chain 51 has a vertical section that is cooperatively arranged between the exit 522 and the entrance 521, so that the carrier carrying the stamping parts enters the pallet from the entrance 521 and is output from the pallet from the exit 522.

[0073] Such an arrangement allows the carrier 6 to move in the up-down direction, which helps to fully utilize the space during the layout of the plant and helps to reduce the space occupied by the stamping parts anti-scratch transportation device.

[0074] In this embodiment, the lifting and conveying unit 5 further includes a power output device 55 , and the power output device 55 is in transmission cooperation with the sprocket 53 via a pin chain 51 .

[0075] Furthermore, if Fig. 9 As shown, the transition transmission unit 4 includes a belt conveyor line 41, and the carrier conveying unit includes a buffer conveyor belt 16 for connecting the discharge end of the slide assembly 1 and one end of the belt conveyor line 41, and the other end of the belt conveyor line 41 is used to transport the carrier 6 carrying the stamping part 7 to the entrance 521.

[0076] Further, refer to Figure 3 As best shown, the power assembly 3 includes a first synchronous belt 35 and a driving shaft 36 for driving the cam 33, the driving wheel 31 and the driven wheel 32 are connected by the first synchronous belt 35, and the driven wheel 32 and the cam 33 are sleeved on the driving shaft 36.

[0077] The follower plate 34 is also connected to a belt clamp 37, and the power assembly also includes a first synchronous mechanism 38 and a second synchronous mechanism 38. The first synchronous mechanism includes a first synchronous wheel 381, a second synchronous wheel 382 and a second synchronous belt 383. The second synchronous belt 383 connects the first synchronous wheel 381 and the second synchronous wheel 382. The second synchronous mechanism 39 includes a third synchronous wheel 391, a fourth synchronous wheel 392 and a third synchronous belt 393. The first synchronous wheel 381 is coaxially arranged with the third synchronous wheel 391. The belt clamp 37 is clamped on the second synchronous belt 383. The third synchronous belt is provided with a mounting seat 3931 for mounting the shifting rod 21.

[0078] The reduction ratio of the first synchronous pulley 381 and the second synchronous pulley 391 can be set to 1:3. Therefore, the horizontal movement stroke of the third synchronous belt 393 is three times the stroke of the cam 33, which plays a role in amplifying the stroke and reducing the size of the cam 33.

[0079] An embodiment of the utility model further provides a method for transporting stamping parts with an anti-scratch function. The method for transporting stamping parts with an anti-scratch function is implemented based on the stamping parts anti-scratch transport device as described above, and the method includes:

[0080] The stamping device is turned on to allow the push rod 21 to reciprocate between the first station and the second station along the first direction on the linear slide rail 22;

[0081] When the push rod 21 is located at the first working position, the empty carrier 6 is input onto the slideway bottom plate 11 along the second direction;

[0082] When the empty carrier 6 reaches the receiving station, the stamping equipment is controlled to discharge the stamped parts 7 from the discharge port, so that the carrier 6 at the receiving station can receive the stamped parts 7 dropped from the discharge port;

[0083] The push rod is kept moving back and forth between the first station and the second station along the first direction.

[0084] An embodiment of the present invention further provides a stamping system, including a stamping device 8 and the stamping parts anti-scratch conveying device as described above.

[0085] In summary, the stamping system provided in this embodiment brings the following technical effects:

[0086] The main shaft of the stamping equipment 8 provides power for the driving wheel 31 and drives the cam 33 to pivot through the driven wheel 32, drives the follower plate 34 to move through the cam 33, and then drives the push rod 21 to move back and forth between the first station and the second station through the transmission cooperation between the follower plate 34 and the push rod 21, driving the carrier 6 on the slide bottom plate 11 to move to the material receiving station along the first direction. The carrier 6 at the material receiving station can receive the stamping part 7 dropped from the discharge port, and then move to the outside of the slide bottom plate 11 along the first direction. The main shaft of the stamping equipment 8 has the same timing as the cam 33, which can make the timing of the stamping of the lever 21 and the stamping equipment consistent, and can timely transport the stamping parts processed along the first direction through the lever, so that the stability of the anti-scratch transportation device of the stamping parts is improved.

[0087] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
