Description

Technical Field

[0001] The invention relates to the technical field of flexible feeding, in particular to a flexible feeding mechanism. Background Art

[0002] Nowadays, the production of toothbrush heads is generally carried out in a fully automated manner. Toothbrush heads are usually of special-shaped structures (head with bristles + connecting handle), and are mostly made of a combination of plastic and soft bristles. The bristles are easily deformed or scratched due to collision and friction. The feeding operation is generally carried out in a flexible feeding manner.

[0003] The existing flexible feeding method for toothbrush heads is to put the disordered toothbrush heads into a flexible vibration plate through a conveyor, start the flexible vibration plate, and vibrate at a high frequency and a small amplitude, so that the toothbrush heads jump in the vibration plate, thereby achieving dispersion, and then grab them through a robot, adjust their posture, and transport them to the next process;

[0004] However, the flexible vibration plate in the above operation steps usually adopts a hard plastic shell and is used in conjunction with a voice coil motor. The voice coil motor realizes high-frequency vibration of the plastic plate. However, the fixed plastic plate cannot change its plate length according to usage requirements. Although a variety of size requirements can be covered by replacing different models of equipment, this process requires frequent adjustment of the hardware structure (such as vibration plate, guide plate, etc.), resulting in increased production line downtime and high switching costs. It is difficult to meet the rapid response needs of small batch and multi-variety production. At the same time, due to the choice of hard materials, the noise generated during vibration is relatively large. Summary of the invention

[0005] The object of the present invention is to provide a flexible feeding mechanism to solve the problems raised in the background technology.

[0013] When the toothbrush head is vibrated and dispersed, the external visual recognition system is used to cooperate with light source one and light source two to start cantilever one, cantilever two and cantilever three to drive the clamping head to clamp the toothbrush head. Cantilever one, cantilever two and cantilever three are all composed of linear motor modules, which can drive the clamping head to move in three directions, so that the clamping head can clamp the toothbrush head in the vibration belt and place it on the discharge fixture. When the photoelectric sensor detects that there is a toothbrush head on the conveyor belt, the conveyor belt transportation is started, and the toothbrush head is transported to the next process.

[0014] Furthermore, the vibration disk body includes an outer shell, a connecting plate, a second light source, and a voice coil motor. The outer shell is fixedly connected to the inner side of the body and between the feeding conveyor belt and the discharge structure.

[0015] Start the vibration plate body, so that the voice coil motors at the four corners start to vibrate the connection plate with high frequency and micro amplitude, and then the high frequency and micro amplitude vibration is transmitted to the vibration plate structure through the connection plate, thereby realizing high frequency and micro amplitude vibration of the vibration belt, so that the toothbrush heads gathered on the vibration belt are dispersed;

[0016] Furthermore, a rotating roller assembly is arranged on the inner side of the vibration belt, and the rotating roller assembly includes a movable roller 1, a movable roller 2, a fixed roller, and a micro motor 3. Two groups of movable roller 1 are transmission-connected to the inner side of one end of the vibration belt, two groups of movable roller 2 are arranged on the inner side of the middle part of the vibration belt, and three groups of fixed rollers are also transmission-connected to the inner side of the vibration belt. A micro motor 3 is fixedly connected to the inner side of the protective shell, and the output end of the micro motor 3 is fixedly connected to a group of the fixed rollers.

[0017] Furthermore, bearing seats are provided at both ends of the movable roller 1, the movable roller 2 and the fixed roller, and the bearing seats of the fixed roller are fixedly connected to the protective shell.

[0018] Furthermore, an adjustment structure 1 and an adjustment structure 2 are provided between the vibration belt and the protective shell, and the adjustment structure 1 and the adjustment structure 2 are fixedly connected.

[0019] Furthermore, the adjustment structure 1 includes a track plate, a slider, a rack 1, a connecting frame 1, a gear 1, and a micro motor 1. The inner side of the protective shell is fixedly connected to the track plate, the inner side of the track plate is slidably connected to the slider, the side of the slider close to the vibration belt is fixedly connected to the connecting frame 1, the upper side of the slider is fixedly connected to the rack 1, the inner side of the protective shell is fixedly connected to the micro motor 1, the output end of the micro motor 1 is fixedly connected to the gear 1, the gear 1 is meshed with the rack 1, and the connecting frame 1 is fixedly connected to the bearing seat corresponding to the movable roller 1;

[0020] The movable edge is fixedly connected to a connecting frame, and the fixed edge is fixedly connected to a protective shell.

[0021] When it is necessary to adapt to the feeding of toothbrush heads of different sizes, the micro motor 1 is started, and the micro motor 1 drives the gear 1 to rotate, so that the gear 1 meshes and drives the rack 1 while rotating, and the rack 1 synchronously drives the slider fixedly connected to it to slide in the track plate, and the slider drives the connecting frame 1 fixedly connected to it to move synchronously, because the connecting frame 1 is fixedly connected to the bearing seat corresponding to the mobile roller 1, and then synchronously drives the mobile roller 1 to move linearly, so as to shorten or extend the vibration belt, and achieve the effect of freely adjusting the length of the vibration belt according to the needs;

[0022] When the connecting frame 1 moves, the connecting frame 1 drives the moving edge fixedly connected thereto to move synchronously, and when the slider moves, it drives the adjusting structure 2 fixedly connected thereto to move synchronously;

The side of the slider close to the second moving roller is fixedly connected to the guide plate, the inner side of the guide plate is slidably connected to the cylindrical rod, the side of the cylindrical rod close to the vibration belt is fixedly connected to the second rack, the side of the second rack close to the vibration belt is fixedly connected to the second connecting frame, the second connecting frame is fixedly connected to the bearing seat corresponding to the second moving roller, the side of the guide plate away from the vibration belt is fixedly connected to the second micro motor, the output end of the second micro motor is fixedly connected to the second gear, the second gear is meshed with the second rack, and a guide groove corresponding to the cylindrical rod is provided on the guide plate;

[0024] The shielding plate is fixedly connected to the second connecting frame, the protective shell is provided with through grooves corresponding to the first movable roller and the second movable roller, and the shielding plate is provided with a through groove corresponding to the first movable roller.

[0025] Since the toothbrush head is generally cylindrical in shape, a cylindrical object is prone to rolling back and forth during high-frequency vibration, which can easily cause adverse effects on its dispersion and posture adjustment. When it is necessary to adjust the inclination of the upper surface of the vibration belt to adapt to the vibration of the toothbrush head and maintain the consistency of the movement direction and posture of the toothbrush head, the micro motor 2 is started, and the micro motor 2 drives the gear 2 to rotate. While the gear 2 rotates, it meshes and drives the rack 2 to move upward along the guide plate through the cylindrical rod, thereby driving the connecting frame 2 and the moving roller 2 to move upward synchronously, so that the moving roller 2 supports the upper vibration belt, so that the vibration belt gradually decreases from the middle to both sides to form a protrusion. The inclination angles on both sides can be freely adjusted according to the number of toothbrush heads. The more the number of toothbrush heads, the larger the inclination angle. By forming a protrusion, when the toothbrush head is vibrated and dispersed, the toothbrush head can be guided to move, the movement direction and posture of the toothbrush head can be controlled, the vibration dispersion effect can be improved, and the subsequent grabbing is convenient.

[0026] Furthermore, the vibration belt is made of polyurethane rubber, and the vibration belt is provided with two areas, one area is provided with evenly distributed rectangular grooves, and the other end area is a smooth surface.

[0027] The vibration belt is provided with two sections, one section has evenly distributed rectangular grooves, and the other end is a smooth surface. By starting micro motor three, micro motor three drives a group of fixed rollers to rotate, and then through the transmission effect of mobile roller one and fixed roller, the section with rectangular grooves and the section with smooth surface can be freely switched to meet the change of friction between the surface of different toothbrush heads and the surface of the vibration belt. When using a section of the vibration belt with rectangular grooves, it is mainly aimed at smoother toothbrush heads, so that during the vibration movement of the toothbrush heads, the rectangular grooves can prevent them from gathering again after vibration. When using a section of the vibration belt with a smooth surface, it is mainly aimed at rougher toothbrush heads, which can prevent gathering according to their own friction.

[0028] Compared with the prior art, the present invention provides a flexible feeding mechanism, which has the following beneficial effects:

[0029] 1. The flexible feeding mechanism achieves the purpose of shortening or extending the vibration belt through the cooperation between the flexible vibration disk, the adjustment structure 1, the adjustment structure 2, and the rotating roller assembly, and achieves the effect of freely adjusting the length of the vibration belt according to the needs, changing the way of covering various size requirements by replacing different models of equipment, and solving the problem that the hardware structure (such as the vibration disk, the guide plate, etc.) needs to be frequently adjusted, resulting in increased downtime of the production line, high switching costs, and difficulty in meeting the rapid response needs of small batch and multi-variety production. At the same time, the inclination of the upper surface of the vibration belt can be adjusted to form a protrusion. The inclination angles on both sides can be freely adjusted according to the number of toothbrush heads. The more the number of toothbrush heads, the larger the inclination angle. By forming a protrusion, when the toothbrush head is vibrated and dispersed, the toothbrush head can be guided to move, the movement direction and posture of the toothbrush head can be controlled, the vibration dispersion effect is improved, and the subsequent grabbing is convenient. The problem that the toothbrush head is generally cylindrical as a whole, but the cylindrical object is prone to rolling back and forth during the high-frequency vibration process, which is easy to disperse and cause adverse effects on posture adjustment is solved.

[0030] 2. The flexible feeding mechanism is made of polyurethane rubber through a vibration belt, and the vibration belt is provided with two sections, one section is provided with evenly distributed rectangular grooves, and the other end section is a smooth surface. The section of the vibration belt with rectangular grooves and the section with a smooth surface can be switched freely, so that toothbrush heads with different smoothness can produce better dispersion effects during vibration dispersion, and the switching is convenient.

[0072] The vibration belt 621 is provided with two sections, one section has evenly distributed rectangular grooves, and the other end is a smooth surface. By starting the micro motor 3 94, the micro motor 3 94 drives a group of fixed rollers 93 to rotate, and then through the transmission effect of the mobile roller 1 91 and the fixed roller 93, the section with the rectangular groove and the section with the smooth surface can be freely switched to meet the change of friction between the surface of different toothbrush heads and the surface of the vibration belt 621. When using the vibration belt 621 with a rectangular groove, it is mainly aimed at smoother toothbrush heads, so that during the vibration movement of the toothbrush heads, the rectangular grooves can prevent them from gathering again after vibration. When using the vibration belt 621 with a smooth surface, it is mainly aimed at rougher toothbrush heads, which can prevent gathering according to their own friction.

[0073] The specific usage and function of this embodiment are as follows:

[0074] When in use, firstly, batches of toothbrush heads are put into the feeding conveyor belt 2 through an external transport mechanism, and the feeding conveyor belt 2 is started. The feeding conveyor belt 2 is an upwardly inclined transmission mechanism, and then the batches of toothbrush heads are put into the vibration disk structure 62;

[0075] By starting the vibration plate body 61, the voice coil motors 614 at the four corners start to vibrate the connection plate 612 with high frequency and small amplitude, and then the high frequency and small amplitude vibration is transmitted to the vibration plate structure 62 through the connection plate 612, thereby achieving high frequency and small amplitude vibration of the vibration belt 621, so that the toothbrush heads gathered on the vibration belt 621 are dispersed;

[0076] When it is necessary to load toothbrush heads of different sizes, the micro motor 76 is started, and the micro motor 76 drives the gear 75 to rotate, so that the gear 75 meshes and drives the rack 73 while rotating, and the rack 73 synchronously drives the slider 72 fixedly connected thereto to slide in the track plate 71, and the slider 72 drives the connecting frame 74 fixedly connected thereto to move synchronously, and since the connecting frame 74 is fixedly connected to the bearing seat corresponding to the mobile roller 91, the mobile roller 91 is synchronously driven to move linearly, so as to shorten or extend the vibration belt 621, and achieve the effect of freely adjusting the length of the vibration belt 621 according to the demand;

[0077] When the connecting frame 1 74 moves, the connecting frame 1 74 drives the moving edge 624 fixedly connected thereto to move synchronously, and when the slider 72 moves, it drives the adjusting structure 2 8 fixedly connected thereto to move synchronously;

[0078] Since the toothbrush head is generally cylindrical in shape, a cylindrical object is prone to rolling back and forth during high-frequency vibration, which may cause adverse effects on its dispersion and posture adjustment. When it is necessary to adjust the inclination of the upper surface of the vibration belt 621 to adapt to the vibration of the toothbrush head and maintain the consistency of the movement direction and posture of the toothbrush head, the micro motor 85 is started, and the micro motor 85 drives the gear 86 to rotate. The gear 86 meshes and drives the rack 83 to move along the guide plate 81 through the cylindrical rod 84 while rotating. The second connecting frame 82 and the second moving roller 92 move upward synchronously, so that the second moving roller 92 supports the vibration belt 621 on the upper side, so that the vibration belt 621 gradually decreases from the middle to both sides to form a protrusion. The inclination angles on both sides can be freely adjusted according to the number of toothbrush heads. The more the number of toothbrush heads, the greater the inclination angle. By forming a protrusion, when the toothbrush heads are vibrated and dispersed, the toothbrush heads can be guided to move, the movement direction and posture of the toothbrush heads can be controlled, the vibration dispersion effect can be improved, and the subsequent grabbing is convenient.

[0079] The vibration belt 621 is provided with two sections, one section is provided with evenly distributed rectangular grooves, and the other end section is a smooth surface. By starting the micro motor 3 94, the micro motor 3 94 drives a group of fixed rollers 93 to rotate, and then the transmission effect of the mobile roller 1 91 and the fixed roller 93 is used to freely switch the section with the rectangular groove and the section with the smooth surface to meet the change of friction between the surfaces of different toothbrush heads and the surface of the vibration belt 621. When using a section of the vibration belt 621 with rectangular grooves, it is mainly aimed at relatively smooth toothbrush heads, so that during the vibration movement of the toothbrush heads, the rectangular grooves can prevent them from gathering again after vibration. When using a section of the vibration belt 621 with a smooth surface, it is mainly aimed at relatively rough toothbrush heads, which can prevent gathering according to their own friction.

[0080] After the vibration dispersion of the toothbrush head is achieved, cantilever 1 52, cantilever 2 53, and cantilever 3 54 are started to drive the clamping head 55 to clamp the toothbrush head. Cantilever 1 52, cantilever 2 53, and cantilever 3 54 are all composed of linear motor modules, which can drive the clamping head 55 to move in three directions, so that the clamping head 55 clamps the toothbrush head in the vibration belt 621 and places it on the discharge fixture 34. When the photoelectric sensor 33 detects that there is a toothbrush head on the conveyor belt 32, the conveyor belt 32 is started to transport the toothbrush head to the next process.

[0081] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
