Description

Technical Field

[0001] The invention relates to an automated device, in particular to a patch feeding device for automatically feeding thin and small patches. Background Art

[0002] The internal components of mobile phones are relatively delicate and fragile. In order to reduce the damage caused by the vibration motor of the mobile phone to the internal electrical components of the mobile phone during the vibration process, a frame is usually set outside the vibration motor of the mobile phone to reduce the vibration impact on other components inside the mobile phone. In order to increase the anti-vibration and anti-fall strength of the frame, some frames are also equipped with metal patches on the outside to play a reinforcing role, especially at the bends of the frame.

[0003] At present, there is no processing equipment that can automatically load the patches on this kind of frame. Most of the loading work is done manually. Since the size of the frame and motor set in the mobile phone is very small, and the metal patches are thinner and smaller, manual loading is not easy and cannot be loaded accurately and effectively. In the production context that requires large-scale processing, manual loading efficiency is low and labor costs are high.

[0004] Therefore, there is an urgent need for a chip loading device with high production efficiency, accurate loading and effective cost reduction to overcome the above problems. Summary of the invention

[0010] Preferably, the patch loading device of the present invention also includes a discharge tray and a receiving tray arranged up and down on the front side of the pushing mechanism, and the material strip covered with a base film and rolled into a roll is loaded on the discharge tray, and the receiving tray is used for separating the base film from the material strip and for winding up the base film.

The driving wheel and the driven wheel are coaxially and abutted in the front-to-back direction. The rotation of the driving wheel can drive the driven wheel to rotate, so that the material strip passing between the two is pushed vertically to the cutting assembly.

[0025] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0026] See also Figure 1 The present invention relates to a thin and compact patch 200. In the present application, the patch 200 is a metal sheet, which is mainly arranged on the frame outside the vibration motor of the mobile phone. The frame forms a surrounding frame in the vibration direction around the vibration motor of the mobile phone to reduce the vibration impact on other components inside the mobile phone, and the patch 200 is welded on the frame to increase the anti-vibration and anti-fall strength of the frame. The shape of the patch 200 corresponds to the shape of the reinforced part of the frame, which can be L-shaped, circular or rectangular. Figure 1 As shown, the patch 200 is roughly rectangular. Since the patch 200 is thin and small, in order to facilitate loading, in the present application, a plurality of equidistantly arranged patches 200 can be preliminarily formed on a thin metal strip 300, and each preliminarily formed patch 200 is only partially connected to the strip 300 at the corresponding punching opening 301 on the strip 300, thereby forming a small punching portion 302. Then, the patches 200 can be separated from the strip 300 one by one by simply cutting off the corresponding punching portions 302.

[0027] See also Figures 1 to 3 The present invention provides a patch loading device 100, which can realize automatic loading of a material belt 300, automatic separation of a patch 200 from the material belt 300, efficient pickup and delivery of separated patches 200, and automatic collection of the material belt 300 that has been flushed from the patches 200, thereby realizing automatic loading of the above-mentioned thin and compact patches 200. The patch loading device 100 of the present invention includes a stamping mechanism 10 and a feeding mechanism 20 arranged in an upper and lower manner on a frame 101, and a pushing mechanism 30 and a pulling mechanism 40 arranged on the front and rear sides of the stamping mechanism 10 and the feeding mechanism 20 on the frame 101. The pushing mechanism 30 pushes the material belt 300 so that the patches 200 arranged equidistantly on the material belt 300 pass through the stamping mechanism 10 and the feeding mechanism 20 one by one. The two feeding heads 21 of the feeding mechanism 20 move alternately to the bottom of the stamping mechanism 10, and the discharging end of the stamping mechanism 10 receives the patches 200 punched out of the punching cut of the material belt 300. The two feeding heads 21 also transfer the received patches 200 to the upper material. The pulling mechanism 40 pulls the material belt 300 to collect the material belt 300 after the patches 200 are punched out.

[0028] Among them, the pushing mechanism 30 can cooperate with the pulling mechanism 40 to push the patches 200 on the material strip 300 between the two horizontally and equidistantly, so that the punching mechanism 10 only needs to move vertically up and down to complete the punching and separation operation of the patches 200 on the material strip 300 with equal frequency. Specifically, the pushing mechanism 30 gradually pushes the material strip 300 toward the punching mechanism 10, and its pushing distance corresponds to the spacing between the patches 200 on the material strip 300, so that the patches 200 on the material strip 300 are sequentially positioned at the position of the punching head of the punching mechanism 10, and correspondingly, any material taking head 21 is located below the patch 200 and in a relative position to the punching head to carry the punched patches 200. In addition, during the punching process, the pushing mechanism 30 can also position the material strip 300, thereby effectively preventing the material strip 300 from shifting due to the punching force, thereby effectively improving the accuracy of punching.

[0029] Of course, in order to protect the material belt 300, a bottom film 400 may also be provided at the bottom of the material belt 300. Then the patch loading device 100 provided by the present invention also needs to separate the material belt 300 from the bottom film 400. Specifically, in this embodiment, the material belt 300 covered with the bottom film 400 can be rolled into a roll for loading, and the patch loading device 100 of the present invention also includes a discharge tray 50 and a receiving tray 60. The discharge tray 50 and the receiving tray 60 are arranged up and down on the front side of the pushing mechanism 30, and the material belt 300 covered with the bottom film 400 and rolled into a roll is loaded on the discharge tray 50, and the free end of the material belt 300 falls from the discharge tray 50 to the pushing mechanism 30, and is connected to the pulling mechanism 40 after passing between the stamping mechanism 10 and the material taking mechanism 20, and the free end of the bottom film 400 is wound on the receiving tray 60.

[0030] Under the action of the receiving drive 61 driving the lower receiving tray 60 to rotate, the unloading drive 51 driving the lower unloading tray 50 to rotate and the pushing force of the pushing mechanism 30, the bottom film 400 is separated from the material belt 300 and the bottom film 400 is wound on the receiving tray 60, and the material belt 300 separated from the bottom film 400 moves toward the direction of the punching mechanism 10 on the pushing mechanism 30. The unloading tray 50 and the receiving tray 60 are arranged in the front side of the pushing mechanism 30 in an up-and-down manner, and the layout is compact, which effectively reduces the volume of the entire device, and the reel automatically unloads and reels the material, which can effectively extend the feeding time, reduce the number of times the material tray is replaced, and is more efficient. Of course, in other embodiments, the material belt 300 can also be in the form of a sheet, so there is no need to set the unloading tray and the receiving tray, and the pushing mechanism 30 directly pushes the material belt 300 horizontally to pass through the punching mechanism 10 and the material taking mechanism 20, and the material belt 300 can also be automatically loaded.

[0031] See also Figure 4The pushing mechanism 30 includes a linear guide groove 31 corresponding to the shape of the material strip 300, a pushing pin 32 and a positioning pin 33 arranged front and back on the upper side of the linear guide groove 31. The material strip 300 moves linearly in the linear guide groove 31, the pushing pin 32 is used to gradually push the material strip 300, and the positioning pin 33 is used to position the material strip 300. Among them, the groove bottom wall of the linear guide groove 31 is flush with the upper end surface of the lower pressing head 11 of the punching mechanism 10, so that the material strip 300 is pushed horizontally into the punching mechanism 10.

[0032] Specifically, the push needle 32 can be driven by the downward drive 321 connected to it to move linearly up and down relative to the linear guide groove 31, so that it can be inserted into the positioning hole 303 on the material strip 300; the push needle 32 can then be driven by the push drive 322 connected to it to move linearly back and forth relative to the linear guide groove 31, and the material strip 300 can be gradually pushed toward the direction of the stamping mechanism 10, so that the patches 200 on the material strip 300 are sequentially aligned with the position of the stamping head of the stamping mechanism 10.

[0033] Among them, the positioning holes 303 are located at the edge of at least one side of the material strip 300. In this embodiment, a plurality of positioning holes 303 are arranged at equal distances on the edges of the left and right sides of the material strip 300. Correspondingly, at least one push pin 32 is provided on each of the left and right sides of the linear guide groove 31, and the push pins 32 on both sides are arranged symmetrically, so that the material strip 300 can be pushed smoothly. Specifically, the number of the push pins 32 is 2, and the two push pins 32 correspond to the positioning holes 303 on the left and right edges of the material strip 300, respectively. The two push pins 32 are connected to the output end of the downward drive 321, and the downward drive 321 is connected to the output end of the push drive 322, so that the two push pins 32 can move downward synchronously and push the material strip 300 synchronously.

[0034] Specifically, the positioning pins 33 can be driven by the positioning driver 331 connected thereto to move linearly up and down relative to the linear guide slot 31, so as to be inserted into the positioning holes 303 at the edge of the material strip 300, thereby strengthening the positioning of the patch 200 when punching and separating on the material strip 300. In this embodiment, the number of the positioning pins 33 is two.

[0035] Continue reading Figure 4 Since the material strip 300 and the base film 400 are separated in the air and then fall onto the pushing mechanism 30, in order to realize the horizontal pushing of the material strip 300, the patch loading device 100 of the present invention also includes a positioning mechanism 70 arranged between the pushing mechanism 30 and the material discharge tray 50. The positioning needle 71 of the positioning mechanism 70 can move up and down relative to the linear guide groove 31 under the drive of the positioning driver 711 until it is inserted into the positioning hole 303 of the material strip 300 to adjust the positioning of the material strip 300, so that the material strip 300 can move linearly in the linear guide groove.

[0036] See also Figure 3 and Figure 5 The punching mechanism 10 includes a lower punch head 11 and an upper punch head 12. A punch head is provided in the upper punch head 12. The upper side end of the lower punch head 11 has a punching hole that matches the punch head and corresponds to the shape of the patch 200. The lower side end of the lower punch head 11 is a discharge end 111. The discharge end 111 has a discharge port connected to the punching hole. The patches 200 on the material strip 300 are pushed to the position corresponding to the punching hole in sequence, that is, the patches 200 are located between the punching hole and the punching head.

[0037] Specifically, in this embodiment, the lower pressure head 11 and the upper pressure head 12 can be both fixed, and the material strip 300 is fixed by the push needle 32, the positioning needle 33 and the pulling mechanism 40 during punching. The punching head moves linearly up and down relative to the lower pressure head 11 under the drive of the punching driver 13 connected thereto, so that the punching head cooperates with the punching hole to punch out the punching portion 302 connecting the patch 200 and the material strip 300, and the patch 200 punched off the material strip 300 falls to the discharge port along the connecting channel between the punching hole and the discharge port, and is carried and transferred by the material taking head 21 located here. The structure of the entire punching mechanism 10 is simple and the layout is reasonable. Of course, in other embodiments, the difference from this embodiment is that the upper press head 12 can move linearly up and down relative to the lower press head 11 under the drive of the downward drive connected thereto, and after cooperating with the lower press head 11 to clamp the material strip 300 between the two, the punching head can then move linearly up and down relative to the lower press head 11 under the drive of the punching drive connected thereto, and the punching portion 302 connecting the patch 200 and the material strip 300 can be punched out through the cooperation of the punching head and the punching hole.

[0038] See also Figures 5 to 7 The two picking heads 21 of the picking mechanism 20 can reciprocate linearly in a direction perpendicular to the pushing direction of the pushing mechanism 30 under the drive of a transposition driver 22 connected to the two, so that the two picking heads 21 can be moved alternately to the bottom of the stamping mechanism 10. The two picking heads 21 can also move linearly up and down relative to the stamping mechanism 10 under the drive of the correspondingly connected lifting driver 23, so that they can be respectively connected to the discharge end 111 of the stamping mechanism 10.

[0039] Specifically, the material taking head 21 includes a columnar member 211 and a positioning member 212. A vacuum suction cup 213 is embedded at the center of the top of the columnar member 211. The top of the columnar member 211 is circumferentially convexly provided with a convex ridge 2111. A bearing area 21a is defined between the circumferential convex ridges 2111. The positioning member 212 is a positioning pin, which is used for the connection between the columnar member 211 and the discharge end 111 of the punching mechanism 10. The suction cup 213 adsorbs the patch 200 flushed out by the punching mechanism 10 into the bearing area 21a. When the material taking head 21 moves upward to take the material, the positioning member 212 and the guide hole of the discharge end 111 are aligned, plugged in and limited, so that the top of the columnar member 211 can extend from the discharge port of the discharge end 111 to a position close to the punching hole. At this time, the vacuum suction cup 213 is ventilated, so as to better receive the patch 200 flushed out by the punching hole.

[0040] See also Figure 8 The pulling mechanism 40 includes a first guide wheel 41, a second guide wheel 42, a guide member 43, a driving wheel 44, a driven wheel 45 and a cutting assembly 46 which are sequentially wound around the feeding belt 300 at the rear side of the punching mechanism 10 from top to bottom. Preferably, at least one tensioning wheel 47 is further provided between the first guide wheel 41 and the second guide wheel 42, so as to strengthen the tension of the material belt 300. The top surface of the first guide wheel 41 is flush with or close to the punching surface of the punching mechanism 10, that is, flush with or slightly lower than the top surface of the lower pressing head 11, so that the material belt 300 is relatively horizontally connected between the upper pressing head 12 and the lower pressing head 11. The driving wheel 44 and the driven wheel 45 are coaxially and abutted in the horizontal direction, and the cutting surface of the second guide wheel 42, the guide surface of the guide member 43, the cutting surface of the cutting assembly 46 and the connecting surface between the driving wheel 44 and the driven wheel 45 are arranged in a straight line in the vertical direction. Specifically, the guide member 43 is in the shape of a square cylinder that is through from top to bottom, and a guide surface corresponding to the shape of the outer contour of the material strip 300 is formed on the inner wall of the rear cylinder 431 of the guide member 43. The cutting assembly 46 includes a cutter 461, a cutting driver 462 connected to the cutter 461, and a positioning block 463 disposed opposite to the cutter 461, and a surface of the positioning block 463 opposite to the cutter 461 forms a cutting surface.

[0041] More specifically, the positioning block 463 includes a positioning guide portion 4631 and a limiting portion 4632. The positioning guide portion 4631 is generally in the shape of a vertical "J". The side of the positioning guide portion 4631 opposite to the cutter 461 forms a cutting surface, and the limiting portion 4632 is rectangular. The limiting portion 4632 is connected to the protruding position of the positioning guide portion 4631, so that a connection groove 463a for the feed belt 300 to vertically connect is formed between the two. Furthermore, the bottom end surface of the limiting portion 4632 is higher than the bottom end surface of the positioning guide portion 4631, and the bottom end surface of the limiting portion 4632 is slightly higher than the top end surface of the cutter 461, that is, the bottom end surface of the limiting portion 4632 and the top end surface of the cutter 461 can be loosely matched, thereby forming a punching groove 463b for the cutter 461 to move back and forth laterally between the bottom end surface of the limiting portion 4632, the cutting surface and the bottom end surface of the positioning guide portion 4631.

[0042] When the driving wheel 44 rotates under the drive of the rotating driver 441 connected to it, so as to drive the driven wheel 45 abutting therewith to rotate, so that the material belt 300 passing through the driving wheel 44 and the driven wheel 45 is pushed vertically toward the direction of the cutting component 46, then the cutter 461 of the cutting component 46 only needs to move back and forth linearly relative to the material belt 300 under the drive of the cutting driver 462 connected thereto, so that the material belt 300 is abutted between the cutter 461 and the positioning block 463, and the material belt 300 can be cut off. After being cut, the material belt 300 that has been separated from the patch 200 is collected in the material receiving box under the guidance of the inclined guide groove 464.

[0043] It should be noted that the patch loading device 100 of the present invention further includes a control system (not shown in the figure), which is electrically connected to the above-mentioned mechanism and is used to control the coordinated actions between the various structures. Among them, the control system is an existing control system, and its structure and control principle are well known in the art, so it will not be described in detail here.

[0044] The following combination Figures 1 to 8 , the working principle of the patch loading device 100 of the present invention is described:

[0045] When the rolled material strip 300 is placed on the material discharging tray 50 and the free end of the bottom film 400 is correspondingly connected with the free end of the material strip 300, the device is started, and the alignment needle 71 moves down to the positioning hole 303 inserted in the material strip 300 to adjust the alignment of the material strip 300, thereby ensuring the flatness of the material strip 300 hanging from a high place at the front end of the linear guide groove 301; then, after the pushing needle 32 moves down and is inserted into the positioning hole 303 of the material strip 300, the alignment needle 71 is reset in the reverse direction, and the pushing needle 32 moves backward to push the material strip 300, so that a patch 200 on the material strip 300 is located between the punching head and the punching hole; then, the positioning needle 33 moves down to fix the material strip 300, and at the same time, a material taking The head 21 moves up to its columnar member 211 inserted into the discharge end 111 and inserted to the position close to the punching hole, and the vacuum suction cup 213 is ventilated; the punching head of the upper pressure head 12 moves down to cooperate with the punching hole, and the patch 200 is punched off the material belt 300, then the material head 21 absorbs and fixes the patch 200 through the vacuum suction cup 213 and moves down with the patch 200 to transfer the material; and the material belt that has been punched off the patch 200 is moved down to the position of the cutting component 46 under the cooperation of the driving wheel 44 and the driven wheel 45; the cutter 461 moves back and forth in a straight line to cut the material belt 300, and the material belt 300 that has been punched off the patch 200 after cutting is collected in the material receiving box under the guidance of the inclined guide groove 464. Repeating the above operation continuously can complete the separation and delivery of the patches 200 on the rolled material belt 300 one by one.

[0046] Compared with the prior art, the stamping mechanism 10 and the picking mechanism 20 of the patch feeding device 100 of the present invention are arranged in an upper and lower manner, and the front and rear sides of the two are respectively provided with a pushing mechanism 30 and a pulling mechanism 40, and the material belt 300 is pushed by the pushing mechanism 30, so that the patches 200 arranged equidistantly on the material belt 300 pass through between the stamping mechanism 10 and the picking mechanism 20 one by one, so that the stamping mechanism 10 separates the patches 200 from the material belt 300 one by one; combined with the picking mechanism 20 The two material taking heads 21 are moved alternately to the bottom of the punching mechanism 10, so that the two material taking heads 21 alternately receive the patches 200 punched out of the punching cutout of the material belt 300 from the material discharging end 111 of the punching mechanism 10, and then transfer the received patches 200 to the upper material. The arrangement of the two material taking heads 21 corresponding to one punching mechanism 10 can effectively improve the efficiency of material taking and feeding; and the pulling mechanism 40 can pull the material belt 300, so as to collect the material belt 300 after the patches 200 are punched out. The patch loading device 100 of the present invention has a reasonable layout, a simple structure, effectively reduces the occupied space, has a high degree of automation and high efficiency, effectively improves the accuracy of loading, and correspondingly reduces the labor cost.

[0047] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
