[0001] This application is a divisional application of the application with the application date of December 6, 2021, application number 202111480482.1, and title "An Automatic Installation Device for the Torsion Spring of a Razor Head". Technical Field

[0002] The present invention belongs to the field of torsion spring installation devices, and particularly relates to a torsion spring automatic feeding device for an automatic installation device of a torsion spring of a razor head. Background Art

[0003] As is well known, generally, the cutter head of an electric shaver includes a cutter head body, a fixed cutter blade fixed on the cutter head body, a movable cutter blade attached to the fixed cutter blade, a pressing block for pressing the movable cutter blade onto the fixed cutter blade, a torsion spring disposed in the cutter head body and buckling the pressing block on the cutter head body, and a clamping seat fixedly provided on the cutter head body.

[0004] Currently, for the installation of the torsion spring of an existing electric shaver, the main method is manual material taking and manual installation.

[0005] However, in the actual production process, when placing the torsion springs, they are easily disordered. Taking the materials is time-consuming and laborious, and very inconvenient. Moreover, since it is difficult to achieve automatic sorting and automatic feeding of the torsion springs, the production efficiency is low, and it cannot meet the needs of large-scale production and assembly of shavers. Therefore, it is necessary to design an automatic installation device for the torsion spring of a razor head. Summary of the Invention

A positioning area matching the torsion spring is formed on the material taking component. When the flipping seat is in the material taking state, the positioning area is aligned with the outlet of the second channel; when the flipping seat is in the material pushing state, the positioning area is connected to the corresponding installation station.

[0009] Preferably, the pushing component includes a first pushing module, a second pushing module, and a third pushing module, wherein the first pushing module, the second pushing module, and the third pushing module are respectively arranged in the first channel, the second channel, and the third channel.

A plurality of the torsion springs are arranged in the sorting track with the torsion arms in contact, and the torsion springs fed by the feeding unit push against the torsion springs in the sorting track to move forward step by step or feed one by one.

[0011] Preferably, the sorting track includes a track body, wherein the track body extends horizontally from the outlet of the feeding unit.

[0012] Furthermore, a groove is formed on the track body, which is sunken inward from the top, and the monolithic track further comprises a first limit module and a second limit module respectively connected to the track body on both sides of the groove opening, wherein the first limit module and the groove form the first channel groove, the second limit module and the groove form the second channel groove, and the first limit module and the second limit module are spaced apart from each other. This arrangement makes it convenient for workers to observe the state of the torsion spring in the channel groove in real time and make adjustments in time.

[0013] Preferably, the side edge of the first limiting module located above the groove is further formed with an extending portion extending downward, and when the torsion spring enters the first channel groove, the extending portion abuts against the torsion spring body;

[0014] Preferably, a support module is provided in the second channel groove, and the torsion arm is supported on the support module. This arrangement effectively prevents material jamming and ensures stable and orderly transmission of multiple torsion springs.

[0037] As Figure 1 shown, the automatic installation device for the torsion spring of the razor head in this embodiment includes an installation platform 1, a torsion spring automatic feeding device 2, a torsion spring installation device 3, and a station switching device 4.

[0038] In this example, the torsion spring N to be installed in this embodiment includes a torsion spring body N0 and two torsion arms N1 extending in the same direction from both ends of the torsion spring body N0.

[0039] Specifically, the installation platform 1 is horizontally arranged, and there are eight installation stations 10 for razor heads on the installation platform 1. Among them, every two of the eight installation stations 10 are divided into a group, and the four groups of installation stations 10 are circumferentially and arrayed around the center line of the installation platform 1.

[0040] In this example, the torsion spring automatic feeding device 2 includes a feeding unit 20, a sorting unit 21, and a feeding unit 22.

[0041] For the convenience of implementation, there are two sets of the feeding unit 20 and the sorting unit 21 respectively, and they are symmetrically arranged on the left and right sides (only the feeding unit and the sorting unit located on the left side are shown in the figure). Such an arrangement facilitates the feeding of two torsion springs at a time and improves the feeding efficiency.

[0042] Specifically, each set of the feeding unit 20 includes a vibrating bowl 200 and a transmission track 201. The vibrating bowl 200 has a spiral track, and the torsion spring N is transmitted from bottom to top along the spiral track. The transmission track 201 extends horizontally outward from the discharge port of the vibrating bowl 200.

[0043] Each blanking unit 21 is a blanking track communicating with the transfer track 201, where the blanking unit 21 includes a track body 210, a first limiting module 211, and a second limiting module 212.

[0044] Combined Figures 2 to 5 As shown, the track body 210 extends horizontally from the discharge port of the transfer track 201, and a groove c0 recessed inward from the top is formed on the track body 210, where the groove c0 is communicated with the transfer track 201. A plurality of torsion springs N are arranged in the groove c0 in contact with the torsion arms N1, and the torsion springs N fed into the transfer track 201 push the torsion springs N in the groove c0 forward step by step.

[0045] The first limiting module 211 and the second limiting module 212 are connected side by side on the track body 210, and the first limiting module 211 and the second limiting module 212 extend along the length direction of the track body 210 respectively.

[0046] Specifically, the first limiting module 211 is fixedly connected to the top of the track body 210 on the left side of the opening of the groove c0, the first limiting module 211 extends rightward from the connection point above the opening of the groove c0, and a first channel groove c1 for positioning and cooperating with the torsion spring body N0 is formed between the first limiting module 211 and the groove c0.

[0047] At the same time, an extension part m extending downward is formed on the right side of the first limiting module 211. When the torsion spring body N0 enters the first channel groove c1, the extension part m abuts against the torsion spring body N0. This setting effectively prevents material jamming and ensures the stable and orderly transfer of a plurality of torsion springs.

[0048] Specifically, the cross section of the extension part m is a trapezoid gradually narrowing from top to bottom, and the extension part m abuts against the torsion spring body N0 from the left inclined surface.

[0049] Specifically, the second limiting module 212 is fixedly connected to the top of the track body 210 on the right side of the opening of the groove c0, the second limiting module 212 extends leftward from the connection point above the opening of the groove c0, and a second channel groove c2 for positioning and cooperating with the torsion arm N1 is formed between the second limiting module 212 and the groove c0.

[0050] At the same time, a support module n is arranged in the second channel groove c2, and the torsion arm N1 is supported on the support module n. This setting provides support for the torsion arm, avoids deformation, and ensures product quality.

[0051] Specifically, the support module n extends upward from the bottom of the second channel groove c2, and the top of the support module n is inclined along the length direction of the torsion arm N1.

[0052] For convenience of implementation, the first limiting module 211 and the second limiting module 212 are arranged at intervals. Such an arrangement facilitates workers to observe the state of the torsion spring in the channel groove in real time and make adjustments in a timely manner.

[0053] In this example, the feed port of the first channel groove c1 is arranged to protrude from the feed port of the second channel groove c2, and the discharge port of the second channel groove c2 is arranged to protrude from the discharge port of the first channel groove c1. With such an arrangement, after the torsion spring enters the first channel groove from the torsion spring body for positioning, the torsion arm then enters the second channel groove. In this way, the positioning accuracy of the torsion spring is effectively improved, facilitating orderly feeding.

[0054] Meanwhile, the material sorting unit 21 further includes a third limiting module 213 and a fourth limiting module 214 respectively arranged at the discharge ports of the first channel groove c1 and the second channel groove c2. The third limiting module 213 passes downward through the first limiting module 211 and extends above one end of the torsion arm N1 of the corresponding torsion spring N, and the fourth limiting module 214 is fixedly connected to the second limiting module 212 and extends downward above the other end of the torsion arm N1 of the corresponding torsion spring N. With such an arrangement, it is ensured that the torsion spring stably enters the feeding unit.

[0055] In this example, the feeding unit 22 includes a pushing structure 220 for the torsion spring and a transfer structure 221 arranged between the pushing structure 220 and the mounting platform 1.

[0056] Specifically, there are two groups of pushing structures 220, which correspond to the two groups of material sorting units 21 one by one. Each group of pushing structures 220 includes a pushing channel a0 communicating with the corresponding material sorting unit 21, a pushing component a1, and a driving component a2.

[0057] Combined Figure 6 As shown, the pushing channel a0 includes a first channel a01, a second channel a02, and a third channel a03 communicating the first channel a01 and the second channel a02.

[0058] Specifically, the first channel a01 is arranged perpendicular to the feeding direction of the corresponding material sorting unit 21. With such an arrangement, it is convenient for the torsion spring to enter the first channel from the material sorting unit, ensuring stable movement of the torsion spring.

[0059] The second channel a02 is arranged parallel to the right side of the first channel a01.

[0060] The third channel a03 extends from the front end of the first channel a01 in a direction perpendicular to the first channel a01 to the second channel a02.

[0061] In this example, the pushing component a1 includes a first pushing module a11, a second pushing module a12, and a third pushing module a13. The first pushing module a11, the second pushing module a12, and the third pushing module a13 are respectively slidably arranged in a first channel a01, a second channel a02, and a third channel a03.

[0062] Specifically, the pushing ends of the first pushing module a11 and the second pushing module a12 are both in a fork shape matching the torsion spring. When pushing, the two tips of the fork-shaped end of the first pushing module a11 respectively abut against the inner sides of the torsion arms of the torsion spring.

[0063] The pushing end of the third pushing module a13 is a flat end. When pushing, the third pushing module a13 pushes on the torsion arm of the torsion spring from the pushing end.

[0064] In this example, the driving component a2 includes a first pushing power member a21, a second pushing power member a22, and a third pushing power member a23 which are respectively connected to the first pushing module a11, the second pushing module a12, and the third pushing module a13 in one-to-one correspondence.

[0065] For the convenience of implementation, the second pushing power member a22 is synchronously connected to the second pushing module a12 located in each second channel a02. With this setting, synchronous feeding of two torsion springs is achieved.

[0066] In this example, the transfer structure 221 includes a flipping seat b0 having a material-taking state and a material-pushing state, a material-taking component b1 installed on the flipping seat b0, and a flipping power member b2 for driving the flipping seat b0 to flip between the material-taking state and the material-pushing state. With this setting, the material transfer stroke is short and the efficiency is high; at the same time, space is saved.

[0067] Combined Figure 7 As shown, the flipping seat b0 is in the material-pushing state, and an inclined plane is formed on the flipping seat b0 that slopes downward from left to right. The flipping power member d2 drives the flipping seat b0 to flip back and forth around the center line of the output shaft.

[0068] Specifically, the material-taking component b1 includes two clamping plates b10 fixedly connected to the bottom of the flipping seat b0. The two clamping plates b10 are parallel and fixedly connected. When the flipping seat b0 is in the material-pushing state, the two clamping plates b10 are horizontally arranged. With this setting, the structure is simple and it is convenient for installation and implementation.

[0069] Meanwhile, two positioning areas q arranged side by side are formed on the sides of the two clamping plates b10 away from the flipping seat b0. When the flipping seat b0 is in the material taking state, each positioning area q is aligned with the corresponding second channel a02; when the flipping seat b0 is in the material pushing state, the positioning area q is connected to the corresponding installation station 10. With such a setting, the positioning area can ensure that the torsion spring does not shake or fall off during the material transfer process, facilitating the installation of the torsion spring onto the razor head during material pushing.

[0070] In this example, the torsion spring installation device 3 includes a material pushing part 30 arranged on the flipping seat b0 and a material discharging part 31 corresponding to the installation station 10 one by one and capable of extending into or withdrawing from the installation station 10. The material pushing part 30 pushes the torsion spring N to the corresponding installation station 10, and the torsion arm N1 of the torsion spring N is buckled on the corresponding material discharging part 31.

[0071] Specifically, the material pushing part 30 includes a sliding seat 300, a top push rod 301 fixedly connected to the sliding seat 300, and a material pushing power part 302. The material pushing power part 302 drives the sliding seat 300 to move towards or away from the positioning area q, and the top push rod 301 accordingly extends into or disengages from the positioning area q.

[0072] The material pushing power part 302 is fixedly connected to the inclined surface of the flipping seat b0. The sliding seat 300 is slidably arranged on the material pushing power part 302 and connected to the output shaft of the material pushing power part 302. The material pushing power part 302 drives the sliding seat 300 to reciprocally slide along the inclined surface.

[0073] The top push rod 301 is divided into two groups, and each group includes three top push rods 301.

[0074] Specifically, there are four material discharging parts 31, which are slidably connected to the installation platform 1. Each material discharging part 31 corresponds to two installation stations 10. During installation, the top push rod 301 pushes and buckles the torsion arm N1 of the torsion spring N on the corresponding material discharging part 31, and the torsion spring body N0 abuts against the card seat of the razor head in the corresponding installation station 10.

[0075] In addition, the station switching device 4 includes a switching power part 40 and a switching shaft 41 connected to the installation platform 1. The switching power part 40 drives the switching shaft 41 to rotate, and the installation platform 1 rotates accordingly to switch the installation station 10.

[0076] Therefore, the implementation process of this embodiment is as follows:

[0077] 1. The sorting unit 2 sorts multiple torsion springs N, enabling them to gradually migrate and enter the material pushing channel a0. Under the pushing of the first top push module a11 and the third top push module a13, the torsion springs N sequentially move along the first channel a01 and the third channel a03, and finally enter the second channel a02, where the second top push module a12 pushes the two torsion springs N on the left and right synchronously for feeding.

[0078] 2. The transfer structure 221 drives the torsion spring N at the outlet of the second channel a02 to flip through the positioning area q and aligns it with the corresponding installation station 10. Then, the ejector rod 301 pushes the torsion spring N into the corresponding installation station 10, so that the torsion arm N1 of the torsion spring N is buckled on the corresponding material discharging part 31, and the torsion spring body N0 abuts against the holder of the razor head in the corresponding installation station 10. Finally, the material discharging part 31 automatically withdraws, and the torsion arm N1 is buckled on the razor head, completing the installation of the torsion spring N.

[0079] 3. The station switching device 4 rotates the installation platform 1 to switch the installation station 10, and repeats the above steps.

[0080] Therefore, this embodiment has the following advantages:

[0081] 1. It can realize automatic feeding, sorting, and feeding of the torsion spring, effectively improving the feeding efficiency of the torsion spring and reducing the labor intensity.

[0082] 2. After the torsion spring is loaded, it can be automatically installed and the station can be automatically switched, effectively improving the production efficiency and meeting the needs of large-scale production and assembly of razors.

[0083] 3. It can realize synchronous feeding and synchronous installation of two torsion springs at one time, with high installation efficiency and cost savings.

[0084] 4. The structure is simple and reliable, and the cost is low.

[0085] The above has made a detailed description of the present invention, aiming to enable those skilled in this field to understand the content of the present invention and implement it. However, it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
