Description

Technical Field

[0001] This application relates to connector processing equipment, and more specifically, to an automatic punching equipment for connector shielding shells. Background Technology

[0002] Electronic connectors are electromechanical components used to achieve electrical / signal connections between circuits or electronic devices. Electronic connectors requiring interference immunity generally have a metal shielding shell. During manufacturing, this metal shielding shell is typically formed on a metal strip through stamping and other processes, with individual shielding shells arranged side-by-side on the strip. The shielding shells are then separated from the strip. Currently, production personnel usually remove the shielding shells one by one from the strip, resulting in relatively low production efficiency and requiring improvement. Utility Model Content

[0003] The purpose of this application is to provide an automatic punching device for connector shielding shells to improve production efficiency.

[0004] To achieve the above objectives, this application provides an automatic punching device for connector shielding shells, which includes a feed channel, a punching assembly, and a pushing assembly. The feed channel is used to place a strip of material with shielding shells arranged at equal intervals. The punching assembly includes an upper punch for pressing down the shielding shells and a lower punch for lifting the shielding shells. The upper and lower punches bend the connection between the shielding shells and the strip vertically. The pushing assembly includes a pushing component for intermittently pushing the strip forward. The pushing component is located above or below the feed channel.

[0005] The technical solution of this application automatically pushes the material belt forward in the material channel with the feeding component, and the punching component automatically separates the shielding shell from the material belt. This realizes the automatic removal of the shielding shell from the material belt, reduces manual intervention, lowers labor intensity, and improves the production efficiency of the shielding shell, which is conducive to increasing production capacity and reducing production costs.

[0006] In an optional configuration, the automatic punching equipment also includes a spool for winding the strip and a clamping roller, which is driven by a motor to rotate and wind up the release paper on the surface of the strip. The feed channel is equipped with a sensor, the position of which corresponds to the bend in the feed channel after the strip is pulled out from the spool; when the sensor detects the strip, the motor stops.

[0007] In the optional scheme, there are corresponding limiting strips on both sides of the material channel, and the limiting strips and the bottom surface of the material channel form a limiting groove for the feeding belt to pass through on both sides respectively.

[0008] In an optional embodiment, the pusher assembly further includes a horizontal cylinder for driving the pusher to reciprocate horizontally and a vertical cylinder for driving the pusher to reciprocate vertically. The pusher is fixedly connected to the output shaft of the vertical cylinder, and the vertical cylinder is fixedly connected to the output shaft of the horizontal cylinder.

[0009] In an optional embodiment, one end of the pusher is provided with at least one protrusion, which is used to insert into the pusher hole of the material strip when the material strip is pushed forward.

[0010] In an optional embodiment, the punching assembly also includes an upper cylinder and a lower cylinder, with the output shaft of the upper cylinder fixedly connected to the upper punch and the output shaft of the lower cylinder fixedly connected to the lower punch.

[0011] In the optional design, the upper punch has two parallel upper punch plates, and the lower punch has two parallel lower punch plates, with the upper and lower punch plates corresponding one to one; the pusher advances one or two shielding shells each time.

[0012] In an optional solution, the automatic punching equipment also includes a pressing assembly, which includes a pressing block and a pressing cylinder. The pressing block is located above the material channel, and the output shaft of the pressing cylinder is fixedly connected to the pressing block. The pressing block is provided with a clearance groove, in which the upper punch moves up and down. The pressing block is used to press the material strip area around the corresponding upper punch.

[0013] In an optional configuration, the bottom surface of the pressure block is provided with at least one positioning pin, and the side of the material strip is provided with several equally spaced positioning holes. When the pressure block presses the material strip, the positioning pin is inserted into the positioning hole.

[0014] In an optional configuration, a cylinder shear is provided at the end of the feed channel. The blade of the cylinder shear corresponds to the port of the feed channel where the material is discharged. The cylinder shear is used to cut the material with the shielded shell cut off.

[0027] An automatic punching device according to one or more embodiments is mainly used to automatically remove the connector shielding shells 91 one by one from the material strip 90. In general, the automatic punching device uses a pushing component 30 to automatically push the material strip 90 forward in the material channel 10, and a punching component 20 to automatically separate the shielding shells 91 from the material strip 90. This achieves automatic removal of the shielding shells 91 from the material strip 90, reduces manual intervention, lowers labor intensity, and improves the production efficiency of the shielding shells 91, which is conducive to increasing production capacity and reducing production costs.

[0028] like Figure 1 As shown, the automatic punching equipment of one or more embodiments is fixed on a platform 100. The height and level of the platform 100 are achieved by four adjusting feet 101. The automatic punching equipment includes a feed channel 10, a punching assembly 20, and a pushing assembly 30. The horizontal feed channel 10 is used to place a strip 90 with equidistantly arranged shielding shells 91. The feed channel 10 is fixed to the platform 100 by two support columns 102. The punching assembly 20 includes an upper punch 21 for pressing down the shielding shells 91 and a lower punch 22 for lifting the shielding shells 91. The lower punch 22 moves upward to lift the shielding shells 91, while the upper punch 21 moves downward to press down the shielding shells 91. The upper punch 21 and the lower punch 22 bend the connection between the shielding shells 91 and the strip 90, causing the metal at the connection to fatigue and break, allowing the shielding shells 91 to detach from the strip 90. The up-and-down movement of the upper punch 21 and lower punch 22 is achieved through conventional electrical drive mechanisms, such as cylinders, linear motors, ball screw mechanisms, or electric push rods. The feeding assembly 30 includes a feeding component 31 for intermittently pushing the material belt 90 forward. Figure 1 The pusher 31 shown is located below the feed channel 10. In at least one other embodiment, the pusher may be located above the feed channel. The horizontal and vertical movement of the pusher 31 is achieved by a conventional electric drive mechanism, such as a cylinder, linear motor, ball screw mechanism, or electric push rod.

[0029] In some embodiments, such as Figure 1As shown, the automatic punching equipment also includes a tray 81 for winding the strip 90 and a clamping roller 82. The clamping roller 82 is a paper clamping roller with a radial gap in the middle. The clamping roller 82 is driven to rotate by an adjustable motor (not shown) to wind up the release paper 83 on the surface of the strip 90. The motor drives the clamping roller 82 to intermittently pull out and wind up the release paper 83, thereby causing the tray 81 to rotate intermittently. The tray 81 itself does not require any other rotational driving force. Figure 1 As shown, a sensor 84 is provided at the inlet section of the feed channel 10. The sensor 84 is located at the bend 901 of the feed strip 90 after it is pulled out of the feed tray 81 and enters the feed channel 10. The sensor 84 is a metal sensor. As the feed strip 90 in the feed channel 10 is gradually pushed forward, the bend 901 of the feed strip 90 will move relatively away from the sensor 84 (e.g., Figure 1 (As shown by the dashed line on the strip), sensor 84 cannot detect strip 90. At this time, the control motor rotates, driving the clamping roller 82 to rotate. The rotating clamping roller 82 pulls the material tray 81 to rotate through the release paper 83. The rotation of the material tray 81 pulls the strip 90 downward, and the strip 90 then approaches sensor 84 (as shown by the dashed line on the strip). Figure 1 (Showing solid line material strip). When sensor 84 detects material strip 90, it controls the motor to stop, and the clamping roller 82 stops rotating. That is, there is no need to continue pulling the material tray 81 to rotate for material discharge through clamping roller 82 and release paper 83. The release paper 83 is wound up and material strip 90 is discharged intermittently through sensor 84, motor, and clamping roller 82, which simplifies the discharge mechanism. Moreover, the discharge of material strip 90 will not affect other subsequent processing of material strip 90. The bending part 901 of material strip 90 plays a certain buffering role, which helps to maintain the continuous operation stability of the equipment.

[0030] In some embodiments, such as Figure 2 As shown, opposing limiting strips 11 are provided on both sides of the material channel 10. A limiting groove 13 is formed between the limiting strip 11 and the bottom surface 12 of the material channel 10. The limiting groove 13 is used for the material belt 90 to pass through from both sides, that is, the material belt 90 is restricted in the limiting groove 13 from both sides, preventing the material belt 90 from detaching from the material channel 10 in the direction perpendicular to the bottom surface 12 of the material channel 10, thus ensuring the continuous and smooth conveying of the material belt 90. Furthermore, as... Figure 2 As shown, the shielding shell 91 of the material strip 90 is located in the middle of the material strip 90 and the shielding shells 91 are arranged at equal intervals. Positioning holes 92 are arranged at equal intervals on both sides of the material strip 90. Only one edge of the shielding shell 91 is connected to the material strip 90, which helps to reduce the difficulty of removing the shielding shell 91.

[0031] In some embodiments, such as Figure 3As shown, the pusher assembly 30 also includes a horizontal cylinder 32 for driving the pusher 31 to reciprocate horizontally and a vertical cylinder 33 for driving the pusher 31 to reciprocate vertically. The pusher 31 is fixedly connected to the output shaft of the vertical cylinder 33. When the output shaft of the vertical cylinder 33 extends, it drives the pusher 31 to rise; when the output shaft of the vertical cylinder 33 retracts, it drives the pusher 31 to fall. The vertical cylinder 33 is fixedly connected to the output shaft of the horizontal cylinder 32. When the output shaft of the horizontal cylinder 32 extends, it drives the vertical cylinder 33 and the pusher 31 to move forward horizontally (direction A); when the output shaft of the horizontal cylinder 32 retracts, it drives the vertical cylinder 33 and the pusher 31 to move backward horizontally (direction B). In a specific implementation, two proximity switches 34 are also set to control the maximum distance of the horizontal cylinder 32's output shaft retraction and extension.

[0032] In some embodiments, Figure 3 The pusher component 31 shown is a vertical plate. For example... Figure 3 As shown, the upper end of the pusher 31 is provided with four protrusions 311, and two protrusions 311 are provided on each side. The material strip 90 is provided with push holes 93 at both ends of each shield shell 91. When the material strip 90 is intermittently pushed forward, the output shaft of the horizontal cylinder 32 retracts to the set position, and then the output shaft of the vertical cylinder 33 extends, so that the four protrusions 311 are inserted into the push holes 93 of the material strip 90. At this time, the output shaft of the horizontal cylinder 32 extends, and pushes the material strip 90 forward a set distance through the protrusions 311 of the pusher 31. After the material strip 90 is in place, the output shaft of the vertical cylinder 33 retracts to disengage the protrusions 311 from the material strip 90.

[0033] In some embodiments, such as Figure 4As shown, the punching assembly 20 also includes an upper cylinder 23, a lower cylinder 26, an upper slider 24, a lower slider 27, and a slide rail 25. The upper cylinder 23, lower cylinder 26, and slide rail 25 are fixed to a vertical plate 103. The upper slider 24 and lower slider 27 are slidably connected to the slide rail 25, which extends vertically. The output shaft of the upper cylinder 23 is fixedly connected to the upper slider 24, and the upper punch 21 is fixedly connected to the upper slider 24. When the output shaft of the upper cylinder 23 extends, it drives the upper punch 21 to move downwards. Similarly, the output shaft of the lower cylinder 26 is fixedly connected to the lower slider 27, and the lower punch 22 is fixedly connected to the lower slider 27. When the output shaft of the lower cylinder 26 extends, it drives the lower punch 22 to move upwards. The cooperation between the upper slider 24, lower slider 27, and slide rail 25 helps improve the accuracy of the vertical movement of the upper punch 21 and lower punch 22, preventing the shielding shell 91 from shifting its force position and causing processing failure. When separating the shielding shell 91, the output shaft of the lower cylinder 26 extends to lift the shielding shell 91, the output shaft of the lower cylinder 26 retracts, and then the output shaft of the upper cylinder 23 extends to press the shielding shell 91 down. After one or two cycles of lifting and pressing, the connection between the shielding shell 91 and the material strip 90 will break due to metal fatigue, and the shielding shell 91 will then separate from the material strip 90.

[0034] In addition, such as Figure 4 As shown, an inclined hopper 28 is provided below the lower punch 22, and the inclination angle of the hopper 28 is adjustable. When the connection between the shielding shell 91 and the conveyor belt 90 is fractured due to metal fatigue caused by lifting and pressing, the shielding shell 91 will detach from the conveyor belt 90. Under the action of gravity, the shielding shell 91 falls into the hopper 28 and descends along the hopper 28. The bottom end of the hopper 28 is aligned with the collection bucket (not shown), so the separated shielding shell 91 eventually enters the collection bucket and is taken away by the operator or the next step of automated machinery (such as a robotic arm).

[0035] In some embodiments, such as Figure 4 As shown, the upper punch 21 has two parallel upper punch plates 211, and the lower punch 22 has two parallel lower punch plates 221. The upper punch plates 211 and lower punch plates 221 correspond one-to-one, so both shielding shells 91 can be lifted and pressed down simultaneously each time. If the pusher 31 ( Figure 3 Each time a shielding shell 91 is advanced (that is, the advancing distance is the width of the shielding shell 91 plus the distance between adjacent shielding shells 91), all shielding shells 91 except the first shielding shell 91 at the end of the material strip 90 will undergo two lifting-pressing cycles. This is suitable for situations where two lifting-pressing cycles are required to separate the shielding shells 91. If the pusher 31 ( Figure 3Each time two shielding shells 91 are advanced (that is, the advancing distance is twice the sum of the width of the shielding shell 91 and the distance between adjacent shielding shells 91), all shielding shells 91 of the material belt 90 undergo a lifting-pressing cycle, which is suitable for situations where the shielding shells 91 can be separated in one lifting-pressing cycle, resulting in higher production efficiency.

[0036] In some embodiments, such as Figure 5 As shown, the automatic punching equipment also includes a pressing assembly 40. The pressing assembly 40 is used to press the material strip 90 area around the upper punch 21 during the operation of the punching assembly 20. Only the shielding shell 91 can move relatively, ensuring better processing results. Specifically, the pressing assembly 40 includes a pressing block 42 and a pressing cylinder 41. The pressing block 42 is located above the material channel 10, and the output shaft of the pressing cylinder 41 is fixedly connected to the pressing block 42. The pressing cylinder 41 is used to push the pressing block 42 downwards, and a proximity switch 44 is provided on its outer side to control the maximum downward stroke of the pressing block 42. The pressing block 42 has a clearance groove 421, in which the upper punch 21 moves up and down. The pressing block 42 surrounds the upper punch 21, thus the pressing block 42 can be used to press the material strip 90 area around the upper punch 21. Furthermore, the material channel 10 has a clearance opening 14 corresponding to the pressing block 42, allowing the pressing block 42 to move downwards and press the material strip 90 together with the bottom surface of the material channel 10.

[0037] In some embodiments, such as Figure 5 As shown, the bottom surface of the pressure block 42 is provided with two parallel downward-facing positioning pins 43, and the side of the strip 90 is provided with several equally spaced positioning holes 92. When the pressure block 42 presses the strip 90, the positioning pins 43 are simultaneously inserted into the positioning holes 92. The strip 90 is first pressed by the pressing assembly 40, and then the punching assembly 20 performs its work. On the one hand, pressing the strip 90 ensures that it will not deform or shift during processing by the punching assembly 20, thus guaranteeing processing quality. On the other hand, the cooperation between the positioning pins 43 and the positioning holes 92 can check whether the shielding shell 91 of the strip 90 is accurately positioned. For example, if the pressure block 42 cannot press down, it may be because the positioning pins 43 cannot be inserted into the positioning holes 92. The reason may be that the shielding shell 91 is not in the correct position. In this case, the position of the strip 90 needs to be adjusted before processing can continue to ensure accurate processing and improve product yield. When pushing the material belt 90 forward, the pressure block 42 will not press the material belt 90 tightly, and the positioning pin 43 will also disengage from the positioning hole 92, so as to avoid the situation where the material belt 90 cannot move forward.

[0038] In some embodiments, such as Figure 6As shown, two opposing pneumatic shears 50 are provided at the end of the feed channel 10, with the cutting edge 51 of the pneumatic shears 50 corresponding to the port of the feed channel 10 that discharges the material strip 90. After the material strip 90 with the cut shield shell 91 is discharged from the feed channel 10 to a predetermined length, the pneumatic shears 50 cut off this section of the material strip 90 with the cut shield shell 91, preventing the useless material strip 90 from being too long and affecting the smooth progress of processing. The cut material strip 90 falls from the hopper 55 into the waste bin (not shown) for collection.
