DETAILED DESCRIPTION

[0055] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0056] like Figures 1 to 6 As shown, the present invention provides a production process for a toothbrush head with automatic hair transplantation, comprising the following steps:

[0057] A. Prepare the body 10;

[0058] B. inserting the bristles into the brush holes of the body 10 using a bristle inserting device;

[0059] C. hot-melt the bristles inserted into the brush hole so that the bristles are bonded to the body 10;

[0060] D. Perform TPE injection molding on the main body 10 to form the covering part 107 .

[0061] In the above process, the main body 10 includes a brush body 101 and a brush plate 102 arranged on one side of the brush body 101, the brush hole is arranged on the brush plate 102, and the brush plate 102 and the brush body 101 are integrally formed; the covering part 107 covers one end of the brush plate 102 for bonding the bristles and covers the connection between the brush plate 102 and the brush body 101.

[0062] That is, when the main body 10 is formed, the present invention fixes the brush body 101 and the brush plate 102, ensuring the stability of the posture of the two, and omitting the subsequent alignment and assembly steps. Compared with the prior art, the number of brush plates 102 with bristles inserted at one time in step B of the present application is reduced, but due to the larger volume of the main body 10, the posture of the main body 10 in the carrier 9 is more stable, and the alignment and assembly steps are reduced. After actual measurement, the overall production efficiency of toothbrush heads can be increased by more than 30%, thus achieving a significant improvement compared with the prior art.

[0063] In this embodiment, step B specifically includes:

[0064] B1. Place the body 10 into the hair insertion device;

[0065] B2. Use the bristle insertion device to transfer the bristles to the top of the body 10;

[0066] B3. Send the bristles into the brush holes of the body 10 and adjust the posture of the bristles in the brush holes by vibration.

[0067] In actual use, the present invention also provides a bristle device for executing step B, which includes a conveying mechanism 2, a bristle transfer turntable 3, a turntable driving mechanism, a vibration module 5 and a bristle feeding mechanism 6. The conveying mechanism 2 is used to transfer the carrier 9 loading the main body 10, the bristle transfer turntable 3 is provided with at least one bristle loading station, the bristle feeding mechanism 6 is used to transfer the bristles to the bristle station 7, the turntable driving mechanism is used to drive the bristle turntable to rotate, and the vibration module 5 is used to drive the bristle station 7 to vibrate so that the bristles fall into the brush holes.

[0068] Specifically, the bristles are automatically loaded by the bristle equipment. Since the bristles are relatively thin, after the bristles are inserted into the brush holes, the vibration module 5 is required to straighten them by vibration to ensure that the postures of the bristles in the same brush hole are basically consistent and the density meets the requirements. The vibration module 5 is preferably a conventional module such as a vibration motor arranged on the bristle loading station / conveying mechanism 2.

[0069] Specifically, the bristle station 7 includes a first bristle-loading member 71, a second bristle-loading member 72 and a first driving module 73, all of which are arranged on the bristle-moving turntable 3. The first bristle-loading member 71 is located directly above the second bristle-loading member 72. The first driving module 73 is used to drive the first bristle-loading member 71 to move back and forth. The first bristle-loading member 71 is provided with a first receiving hole for accommodating the first bristles 105, and the second bristle-loading member 72 is provided with a second receiving hole for accommodating the second bristles 106. Step B2 specifically includes:

[0070] B21. The brushing station 7 moves to the brush feeding mechanism 6;

[0071] B22. The first drive module 73 drives the first hair-loading member 71 to move to leave the second hair-loading member 72 directly above;

[0072] B23. The brush feeding mechanism 6 feeds the second brush 106 to the second receiving hole;

[0073] B24. The first drive module 73 drives the first loading member 71 to move to the top of the second loading member 72, and uses the first loading member 71 to cover the top opening of the second container hole;

[0074] B25. The brush feeding mechanism 6 feeds the first brush 105 to the first receiving hole;

[0075] B26. The turntable driving mechanism drives the bristle turntable to rotate so that the bristle station 7 moves to the top of the main body 10.

[0076] In the above process, there is no particular order in which B21 and B22 are executed, and the specifications of the first bristles 105 and the second bristles 106 are different.

[0077] In order to improve the appearance of the toothbrush and the brushing effect, currently a toothbrush head may have bristles of different colors / specifications, and each bristle is located in a different hole. Based on this, the present invention uses different bristle pieces to accommodate different bristles, and then loads the different bristles into different brush holes of the brush plate 102 in sequence, thereby achieving an automatic loading effect.

[0078] Of course, after testing, it was found that when the angle between the outer bristles and the brush plate 102 changes, for example, from the original 90° to 87°, the brushing range and effect of the bristles will be improved. Figure 6 For example, the brush hole perpendicular to the brush plate 102 is the first brush hole 103, and the second brush hole 104 is at an angle of 87-88° to the brush plate 102. When executing steps B21-B26, the inclination of the second receiving hole is substantially the same as that of the second brush hole 104, so the second brush bristles 106 in the second receiving hole slide into the second brush hole 104 along the second receiving hole; and the first brush bristles 105 in the first receiving hole directly fall into the first brush hole 103.

[0079] The above method mainly allows the bristle feeding mechanism 6 to feed the first bristles 105 and the second bristles 106 separately based on the different angles required by the two, so as to ensure that the posture and density of the bristles meet the requirements.

[0080] Specifically, a baffle plate 76 is movably provided at the bottom of the second hair-mounting member 72, and the baffle plate 76 is connected to a linear drive module 77. The baffle plate 76 has a first feed hole and a second feed hole. The first feed hole is corresponding to the first receiving hole, and the second feed hole is corresponding to the second receiving hole. The linear drive module 77 is used to drive the baffle plate 76 to move back and forth.

[0081] The hair removal turntable 3 is also provided with a second driving module 74 and a guide member 75, and the second driving module 74 is used to drive the second hair loading member 72 and the guide member 75 to move back and forth; step B26 specifically includes:

[0082] B261. The brush station 7 is rotated to the conveying mechanism 2 so that the second receiving hole is opposite to the feeding hole;

[0083] B262. The second bristles 106 in the second container hole fall into the body 10 under the action of gravity;

[0084] B263. Vibration of the vibration module 5 to correct the posture of the second bristle 106 in the body 10;

[0085] B264. The second drive module 74 drives the second loading member 72 and the guide member 75 to move simultaneously, so that the guide member 75 moves to the bottom of the first loading member 71, and the first receiving hole is connected to the feed hole through the guide member 75;

[0086] B265. The bristles in the first container hole fall into the body 10 under the action of gravity;

[0087] B266. Vibrate the vibration module 5 to correct the posture of the first bristles 105 in the main body 10.

[0088] In actual use, the second drive module 74 is preferably a cylinder, and the second hair-fitting member 72 and the guide member 75 are connected by a connecting member 78, so that the second drive module 74 can drive the two to move simultaneously. In addition, the linear drive module 77 is preferably a cylinder, which has two states, for example, the cylinder is fully retracted and the cylinder is fully extended. When it is necessary to release the second bristles 106, the piston rod of the cylinder is completely retracted so that the second feed hole is located directly below the second bristle-loading piece 72, allowing the second bristles 106 to enter the brush plate 102 along the second feed hole; and when it is necessary to release the first bristles 105, the piston rod of the cylinder is completely extended so that the first feed hole is located directly below the second bristle-loading piece 72, and the second drive module 74 is used to drive the second bristle-loading piece 72 and the guide piece 75 to move, so that the guide piece 75 is located directly below the first bristle-loading piece 71, allowing the first bristles 105 to fall into the brush plate 102; of course, when it is not necessary to release the bristles, it is only necessary to fully extend the piston rod of the cylinder so that the first feed hole is located directly below the second bristle-loading piece 106, and the material blocking effect is achieved by staggering.

[0089] It should be noted that the present invention only shows the positional relationship between the first hair mounting member 71, the second hair mounting member 72 and the shielding plate 76, but the actual assembly method of the three and the hair removal turntable 3 should be obtained by those skilled in the art after debugging and testing, and will not be repeated here.

[0090] The above structure can achieve the effect of automatic and batch feeding of brush hair. The brushing stations 7 on the brush transfer turntable 3 are preferably two or four, which can be set according to the rhythm of the conveying mechanism 2 and the brush feeding mechanism 6.

[0091] In this embodiment, the conveying mechanism 2 includes a first transmission module 21, a second transmission module 22, a transverse frame 23 and a transverse driving module 24. Both ends of the transverse frame 23 are respectively provided with loading stations for accommodating the carrier 9. The transverse driving module 24 is used to drive the transverse frame 23 to move back and forth. The first transmission module 21 and the second transmission module 22 are respectively used to take and place the main body 10 in the two loading stations.

[0092] The structures of the first transmission module 21 and the second transmission module 22 are basically the same, for example, they can be manipulators. The first transmission module 21 and the second transmission module 22 are respectively used to take and place the main body 10 at the two loading stations, and the carrier 9 on the loading station is preferably fixed to the loading station by screws: for example, when the loading station on one side completes the insertion and hot melting, the transverse drive module 24 drives the transverse frame 23 to move, so that the loading station on this side moves to the first transmission module 21, and the loading station on the other side moves to the insertion device, so that the first transmission module 21 replaces the main body 10 in the carrier 9 on this side, while the insertion device inserts the main body 10 in the carrier 9 on the loading station on the other side, which makes rational use of time and improves efficiency.

[0093] In this embodiment, the carrier 9 is provided with a plurality of grooves 91 for accommodating the body 10 , a hot melt module 93 is provided at the bottom of the groove 91 , and the carrier 9 is provided with a socket 92 , through which the hot melt module 93 is electrically connected to an external power connection module.

[0094] After the bristles are inserted, an external power module is inserted into the socket 92 and supplies power to the hot melt module 93, so that the hot melt module 93 generates heat after receiving power. Since a portion of the first bristles 105 and the second bristles 106 will inevitably protrude directly below the bottom of the brush plate 102 during the insertion of the bristles, the hot melt module 93 plays a role in hot melting this portion, so that the first bristles 105 and the second bristles 106 are bonded to the brush plate 102 for fixing, ensuring that the first bristles 105 and the second bristles 106 will not separate from the brush plate 102.

[0095] The present invention integrates the hot melt module 93 in the carrier 9, achieving the effect of hot melting immediately after the bristles are inserted, without the need to transfer the carrier 9, ensuring that the bristles will not fall off due to movement before hot melting, thereby ensuring quality and effect.

[0096] Specifically, the hot melt module 93 can be lifted and lowered in the carrier 9, the hot melt module 93 is provided with an electromagnet 94, the carrier 9 is provided with a magnetizable metal part 95, and an elastic part 96 is provided between the hot melt module 93 and the carrier 9; step C specifically includes:

[0097] C1. Use the external power module to insert the jack 92 so that the hot melt module 93 and the electromagnet 94 are energized;

[0098] C2. The hot melt module 93 is energized to heat up, and the electromagnet 94 is energized to generate a magnetic field to magnetically attract the metal member 95 to drive the hot melt module 93 to rise;

[0099] C3. The hot melt module 93 contacts the bottom of the body 10 and hot melts the bristles;

[0100] C4. After a preset time t, the hot melt module 93 and the electromagnet 94 are de-energized, and the elastic member 96 is used to force the hot melt module 93 to separate from the bottom of the body 10 .

[0101] That is, during hot melting, the hot melting module 93 will rise to contact the first bristles 105 and the second bristles 106, and ensure heat transfer to the first bristles 105 and the second bristles 106 by direct contact, so as to achieve the effect of rapid hot melting. After the hot melting is completed, the electromagnet 94 is powered off and loses its magnetism. Under the elastic force of the elastic member 96 (preferably a spring) and the gravity of the hot melting module 93, the hot melting module 93 descends and separates from the melted plastic. At this time, the plastic will not be greatly bonded to the hot melting module 93 due to its high temperature, thereby avoiding the adhesion between the two and affecting the smooth separation of the body 10.

[0102] Of course, after being used several times, the staff is required to clean the hot melt module 93 to remove the plastic adhered to the hot melt module 93 to ensure that step C can be performed smoothly.

[0103] Specifically, in step C2, after the hot melt module 93 is powered, the electromagnet 94 is powered after t' time. This function can be realized by a delay circuit, and the purpose is to allow the hot melt module 93 to reach a certain temperature before contacting the first bristles 105 and the second bristles 106 to ensure the hot melt effect. The hot melt module 93 can be heated by a conventional resistor.

[0104] In this embodiment, step D specifically includes:

[0105] D1. Pick up the body 10 in the carrier 9;

[0106] D2. Place the body 10 into the transition container;

[0107] D3. Visually identify the main body 10 in the transition container to determine whether the main body 10 is qualified;

[0108] D4. Then adjust the posture of the qualified body 10, and remove the unqualified body 10 from the transition container;

[0109] D5. Pick up the qualified body 10 in the transition container and put it into the injection mold;

[0110] D6. Perform TPE injection molding on the qualified main body 10 in the injection mold to form the covering part 107.

[0111] That is, after the hot melt is completed, the body 10 will be transferred to a transition container, the top of which has a visual device, which analyzes the appearance of the body 10, the density of each bristle on the body 10, the posture, etc. according to the image of each body 10, so as to determine whether the body 10 is qualified. If the body 10 has defects in appearance, or the bristle density / posture does not meet the requirements, the body 10 is unqualified and will be taken out by the corresponding robot. After the body 10 is tested, it is taken out by the robot and placed in the injection mold for TPE injection molding, thereby forming a covering 107 that covers one end (i.e., the bottom) of the hot-melt bristles of the brush plate 102 and the connection between the brush plate 102 and the brush body 101, completing the automated production process of the toothbrush head.

[0112] It should be noted that the bristle feeding mechanism 6 of the present application is a conventional structure in the art and will not be described in detail here.
