Description

Technical Field

[0001] This utility model relates to the field of toothbrush production technology, and in particular to an automatic welding laser engraving equipment for toothbrush production. Background Technology

[0002] The toothbrush production process includes welding and laser engraving. Specifically, the separately formed brush head and brush shell are assembled and welded together, and then the back of the brush shell is laser engraved.

[0003] Currently, the welding and laser engraving steps are performed separately, which obviously leads to a decrease in production efficiency. Summary of the Invention

[0004] This utility model addresses the problems of existing technology by providing an automatic welding and laser engraving equipment for toothbrush production, which realizes one-stop assembly and welding of brush head and brush shell, and automatically laser engraves the brush shell after welding.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides an automatic welding and laser engraving equipment for toothbrush production, including a machine body, a turntable mechanism, a positioning mechanism, an ultrasonic welding mechanism, a laser engraving mechanism, and a feeding mechanism, all of which are disposed on the machine body. The turntable mechanism is provided with multiple carriers, and the positioning mechanism, ultrasonic welding mechanism, laser engraving mechanism, and feeding mechanism are arranged along the rotation direction of the turntable mechanism.

[0007] The positioning mechanism is used to position the brush head and brush shell to be welded onto the carrier; the ultrasonic welding mechanism is used to weld the brush head and brush shell to form the product; the laser engraving mechanism is used to flip the product and then perform laser engraving; and the unloading mechanism is used to unload the laser-engraved product.

[0008] Furthermore, the positioning mechanism includes a feeding rack, a pneumatic finger mounted on the feeding rack, and two positioning components respectively mounted on the two output ends of the pneumatic finger. The two positioning components are arranged facing each other. The pneumatic finger is used to drive the two positioning components to move closer or further away from each other. The two positioning components cooperate to clamp and position the brush head and brush shell to be welded on the carrier.

[0009] Furthermore, the positioning element includes a connecting part and a positioning part. The top of the connecting part is mounted on the output end of the pneumatic finger, and the positioning part is located at the bottom of the connecting part near one end of another positioning element. The connecting part and the positioning part are perpendicular to each other.

[0010] Furthermore, the ultrasonic welding mechanism includes an ultrasonic generator and a welding lifting module. The welding lifting module is installed on the machine body, and the ultrasonic generator is located directly above the turntable mechanism. The welding lifting module is used to drive the ultrasonic generator to move up and down.

[0011] Furthermore, the laser engraving mechanism includes a laser emitter, a moving mechanism, and a gripping robot. The laser generator and the moving mechanism are both mounted on the machine body. The moving mechanism is used to drive the gripping robot to move. The gripping robot is used to grip and flip the product. The laser emitter is used to laser engrave the flipped product. The gripping robot is also used to put the laser-engraved product back into the carrier.

[0012] Furthermore, the moving mechanism includes a lifting module and a flipping module. The lifting module is used to drive the gripping robot to lift and lower, and the flipping module is used to drive the gripping robot to flip around a horizontal line as an axis.

[0013] Furthermore, the unloading mechanism includes an unloading slide, a clamping module, and a translation module.

Detailed Implementation

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3As shown, this utility model provides an automatic welding and laser engraving equipment for toothbrush production, including a machine body 1, a turntable mechanism 2, a positioning mechanism 3, an ultrasonic welding mechanism 4, a laser engraving mechanism 5, and a feeding mechanism 6, all disposed on the machine body 1. The turntable mechanism 2 is provided with multiple carriers. The positioning mechanism 3, the ultrasonic welding mechanism 4, the laser engraving mechanism 5, and the feeding mechanism 6 are arranged along the rotation direction of the turntable mechanism 2. The positioning mechanism 3 is used to position the brush head and brush shell to be welded onto the carrier. The ultrasonic welding mechanism 4 is used to weld the brush head and brush shell to form the product. The laser engraving mechanism 5 is used to flip the product and perform laser engraving. The feeding mechanism 6 is used to feed the laser-engraved product.

[0021] In actual use, four carriers are used, arranged in a circular array around the center of the turntable mechanism 2 on top of the turntable mechanism 2. During operation, the positioning mechanism 3 first activates to create a channel directly above the carriers. Then, a worker or robotic arm places the brush shell and brush head into the carriers along the channel. Subsequently, the positioning mechanism 3 resets and the turntable mechanism 2 rotates, causing the brush shell and brush head to rotate to the ultrasonic welding mechanism 4. The ultrasonic welding mechanism 4 then ultrasonically welds the brush shell and brush head to form a single product. Next, the turntable mechanism 2 rotates, causing the product to rotate to the laser engraving mechanism 5. The laser engraving mechanism 5 flips the product so that the brush shell faces upward for laser engraving. Finally, the turntable mechanism 2 rotates, causing the product to move to the unloading mechanism 6, which unloads the product.

[0022] This invention can complete ultrasonic welding and laser engraving of products, and the entire process can be automated, thereby improving efficiency.

[0023] In this embodiment, the positioning mechanism 3 includes a feeding rack 31, a pneumatic finger 32 mounted on the feeding rack 31, and two positioning components 33 respectively mounted on the two output ends of the pneumatic finger 32. The two positioning components 33 are arranged facing each other. The pneumatic finger 32 is used to drive the two positioning components 33 to move closer or further away from each other. The two positioning components 33 cooperate to clamp and position the brush head and brush shell to be welded on the carrier.

[0024] This utility model forms a channel through the cooperation of two positioning parts 33, so that workers or external robotic arms can place the brush head and brush shell into the carrier along the channel, achieving a positioning effect and ensuring that the brush head and brush shell are assembled in the carrier in one go, so as to facilitate subsequent welding.

[0025] Specifically, the positioning component 33 includes a connecting portion 34 and a positioning portion 35. The top of the connecting portion 34 is mounted on the output end of the pneumatic finger 32, and the positioning portion 35 is located at the bottom of the connecting portion 34 near one end of the other positioning component 33. The connecting portion 34 and the positioning portion 35 are perpendicular to each other. That is, the connecting portion 34 and the positioning portion 35 form an "L" structure to ensure that the distance between the two positioning portions 35 is small, so that a channel with a width that just meets the requirements can be formed under the drive of the pneumatic finger 32.

[0026] In this embodiment, the ultrasonic welding mechanism 4 includes an ultrasonic generator 41 and a welding lifting module 42. The welding lifting module 42 is installed on the machine body 1, and the ultrasonic generator 41 is located directly above the turntable mechanism 2. The welding lifting module 42 is used to drive the ultrasonic generator 41 to move up and down.

[0027] Specifically, the welding lifting module 42 is preferably a conventional linear module with a cylinder or motor as the power source. During operation, the welding lifting module 42 drives the ultrasonic generator 41 to descend. The ultrasonic generator 41 contacts the position to be welded on the brush head (mainly the outer periphery of the bristles) and applies continuous pressure to achieve a secondary assembly effect between the brush head and the brush shell. When the ultrasonic generator 41 descends to the preset height, the ultrasonic generator 41 works and uses ultrasonic waves to weld the plastic brush head and the brush shell, thereby ensuring that the brush head and the brush shell will not separate.

[0028] In this embodiment, the laser engraving mechanism 5 includes a laser emitter 51, a moving mechanism 52, and a gripping robot 53. The laser emitter 51 and the moving mechanism 52 are both mounted on the machine body 1. The moving mechanism 52 is used to drive the gripping robot 53 to move. The gripping robot 53 is used to grip and flip the product. The laser emitter 51 is used to laser engrave the flipped product. The gripping robot 53 is also used to put the laser-engraved product back into the carrier.

[0029] In actual use, the moving mechanism 52 includes a lifting module 55 and a flipping module 56. The lifting module 55 is used to drive the gripping robot 53 to lift and lower, and the flipping module 56 is used to drive the gripping robot 53 to flip around the horizontal line as an axis.

[0030] The lifting module 55 is preferably a conventional linear drive module, while the flipping module 56 can be a motor, rotary cylinder, etc. The flipping module 56 is installed at the output end of the lifting module 55, and the gripping robot 53 is installed at the output end of the flipping module 56. Since laser engraving is performed on the back of the brush shell, this utility model uses the lifting module 55 and the flipping module 56 in combination. Specifically, the lifting module 55 controls the gripping robot to descend to both sides of the product located in the carrier. Then, the gripping robot 53 grips the product and rises a certain distance under the drive of the lifting module 55. The gripping robot 53 then flips the product. After that, the laser emitter 51 laser engraves the product gripped by the gripping robot 53. Finally, the gripping robot 53 puts the laser-engraved product back into the carrier. The entire process is automated, improving efficiency.

[0031] In this embodiment, the unloading mechanism 6 includes an unloading slide 61, a clamping module 62, and a translation module 63. The translation module 63 is used to drive the clamping module 62 to move back and forth. The clamping module 62 is used to pick up the laser-engraved product on the carrier and transfer the product to the unloading slide 61. The unloading slide 61 is used to guide the product to slide into an external container.

[0032] The clamping module 62 is preferably powered by a finger cylinder, while the translation module 63 is a conventional linear drive module. The translation module 63 drives the clamping module 62 to move to the carrier, where the clamping module 62 picks up the product and moves it to the unloading slide 61 under the drive of the translation module 63. The clamping module 62 puts the product into the unloading slide 61, allowing the product to move along the unloading slide 61 under gravity to an external container for storage.

[0033] Of course, in order to minimize interference between actions, the unloading mechanism 6 may also include a module (not shown in the figure) for driving the clamping module 62 to rise and fall.

[0034] It should be noted that although the specific shape and position of the vehicle are not shown in the drawings, the vehicle is a conventional structure in the art, and those skilled in the art can clearly understand how it is set up under the description of this embodiment. Therefore, it is not necessary to show it in the drawings, nor will it prevent those skilled in the art from implementing this invention.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
