Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to a variable-distance burial device. Background Technology

[0002] The secondary molding of toothbrush handles is mainly used to improve anti-slip performance and structural strength, and is commonly seen in rubber overmolding processes. The specific process principle is as follows: Secondary molding typically involves two steps: base molding and overmolding. Base molding first uses an injection molding machine to create the plastic base layer (such as PP or PE material) for the toothbrush handle, forming the main structure. Overmolding involves placing the base layer into a mold and then using an overmolding injection molding machine to inject rubber or silicone (such as TPR or TPE material) to cover the surface and form an anti-slip layer.

[0003] In the current toothbrush manufacturing industry, mold design typically needs to accommodate the production requirements of both finished and semi-finished brush handles. To achieve this, existing design approaches often ensure that the spacing between the two within the mold remains consistent. However, the drawbacks of this approach are obvious: it not only leads to a significant increase in mold size but also necessitates larger injection molding machines, resulting in high equipment investment costs for companies.

[0004] To effectively reduce costs and improve production efficiency, a compact mold structure design is crucial. However, once a compact design is adopted, it becomes difficult to maintain a consistent gap between the finished and semi-finished brush handles, and the requirements for embedding accuracy become extremely stringent.

[0005] Currently, the production methods for toothbrush handles are mostly complex and cumbersome in design. Companies typically need two sets of automated equipment to complete the entire production process: one set dedicated to removing finished and semi-finished products, and the other responsible for adjusting the pitch and embedding the semi-finished products. This decentralized operation mode not only increases the complexity of the equipment but also extends the overall production cycle.

[0006] More seriously, existing toothbrush handle embedding jigs cannot meet the high-precision embedding requirements of finished and semi-finished toothbrush handles with different spacing within the mold. This deficiency has become a key bottleneck restricting capacity and efficiency improvements, directly leading to a decline in enterprise capacity and a reduction in production efficiency.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] The foregoing and other technical contents, features, and effects of this utility model will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present utility model. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0029] Reference Figure 1 As shown, a variable-pitch re-embedding device includes an installation module 10, an extraction module 20, and a variable-pitch module 30. The installation module 10 is used to integrate and install the extraction module 20 and the variable-pitch module 30, and is installed in conjunction with an extraction robot. The extraction module 20 is used to extract the finished toothbrush handle. The variable-pitch module 30 is used to extract the semi-finished toothbrush handle and re-embedding it into the secondary forming area through variable-pitch re-embedding.

[0030] Among them, combined Figure 2 The mounting module 10 includes a base plate 11, at least one push drive source 15 mounted on the base plate 11, a pressure regulating valve 13 connected to the push drive source 15, and a first hydraulic damper 14 mounted on the base plate 11. The push drive source 15 is a commercially available cylinder. The working end of the first hydraulic damper 14 faces the opposite direction to the working end of the push drive source 15. The first hydraulic damper 14 buffers the push of the push drive source 15. In this embodiment, three push drive sources 15 are provided, which are arranged in a roughly triangular pattern. This arrangement can evenly distribute the force in three directions, avoiding local deformation or damage caused by force concentration. At the same time, it can more accurately control the direction and position of movement. This arrangement can reduce the overall movement error caused by the movement error of a single cylinder.

[0031] Furthermore, the substrate 11 can adopt a hollow design to reduce the overall weight of the fixture. Four first positioning guide posts 12 are mounted on the substrate 11, and the four first positioning guide posts 12 are respectively located at the four corners of the substrate 11. The first positioning guide posts 12 are used to position the variable pitch module 30.

[0032] The mounting module 10 also includes a first mounting plate 16 mounted on the base plate 11 and a lifting ring 17 mounted on the base plate 11. The first mounting plate 16 and the lifting ring 17 are on the same side as the working end of the first hydraulic buffer 14. The first mounting plate 16 is used for mounting the robot. The lifting ring 17 facilitates the installation and removal of the variable pitch retrieval device.

[0033] Combination Figure 3 The extraction module 20 includes a mounting unit 23 mounted on one side of the substrate 11, a second mounting plate 22 disposed on the mounting unit 23, and multiple sets of vacuum suction cup units 21 disposed on the second mounting plate 22.

[0034] Specifically, the vacuum suction cup unit 21 includes at least two vacuum suction cups, one of which is located at the connection between the toothbrush head and the handle, and the other is located at the bottom of the toothbrush handle. In this embodiment, the vacuum suction cup unit 21 preferably includes three vacuum suction cups, located at the connection between the toothbrush head and the handle, the middle of the toothbrush handle, and the bottom of the toothbrush handle, respectively. By placing vacuum suction cups at different positions on the toothbrush, the toothbrush can be made more stable during gripping and handling, reducing the risk of dropping or damage due to weak gripping. The three vacuum suction cups being located at different positions can evenly distribute the gripping force across the toothbrush head, the middle of the handle, and the bottom, avoiding localized deformation or damage caused by concentrated force.

[0035] The mounting unit 23 includes two supports. Each support has a first connecting portion and a second connecting portion. A second mounting plate 22 is fixed to the first connecting portion. The second connecting portion is fixed to one side of the base plate 11.

[0036] Combination Figure 4 The pitch control module 30 includes a third mounting plate 32 slidably connected to the base plate 11, multiple toothbrush-shaped carriers 38 movably mounted on the third mounting plate 32, and a pitch control drive source 31 connected to the toothbrush-shaped carriers 38. The drive source 15 is pushed towards the third mounting plate 32. The pitch control drive source 31 employs a pitch control cylinder, which provides pitch control power. It has a long stroke, a flat structure, and a mounting height approximately 30%-50% lower than a standard cylinder, making it particularly suitable for space-constrained equipment and significantly lighter.

[0037] The toothbrush contour carrier 38 includes a fourth mounting plate 381, a contouring platform 382 fixed to the fourth mounting plate 381, and at least one vacuum suction cup 383 disposed within the contouring platform 382. Two contouring platforms 382 can be fixed simultaneously on the fourth mounting plate 381, which can make full use of the fourth mounting plate 381 and improve its utilization rate.

[0038] Furthermore, the contouring stage 382 is equipped with three vacuum suction cups 383, which are located at the connection between the toothbrush head and the handle, the middle of the toothbrush handle, and the bottom of the toothbrush handle, respectively.

[0039] The variable pitch module 30 also includes an air distribution module 34. The air distribution module 34 is configured to distribute the air supply to the vacuum suction cups 383 of each toothbrush contour carrier 38. The air distribution module 34 is a commercially available air distributor.

[0040] Furthermore, the pitch module 30 also includes a lever 33 that connects multiple toothbrush-shaped carriers 38.

[0041] Furthermore, the pitch module 30 also includes a limiting buffer unit 36 ​​disposed on one side of the third mounting plate 32 and close to the pitch drive source 31. The limiting buffer unit 36 ​​is configured to limit and buffer the toothbrush contour carrier 38. The limiting buffer unit 36 ​​includes a fixed base and a second hydraulic buffer mounted on the fixed base. The actuating end of the second hydraulic buffer faces the toothbrush contour carrier 38.

[0042] Furthermore, the pitch module 30 also includes a detection unit 39 located on one side of the third mounting plate 32 and close to the pitch drive source 31. The detection unit 39 is used to detect the pitch position of the toothbrush contour carrier 38. The detection unit 39 can use a laser rangefinder to determine the position of the toothbrush contour carrier 38.

[0043] A guide unit 37 is provided between the substrate 11 and the third mounting plate 32. The guide unit 37 is configured to guide the third mounting plate 32 to move horizontally on the substrate 11. Specifically, the guide unit 37 includes a guide rail disposed along the length direction of the substrate 11 and a slider that slides along the guide rail. The slider and the third mounting plate 32 are fixedly connected.

[0044] The second mounting plate 22 and the third mounting plate 32 are on the same horizontal plane. This ensures that the components mounted on the second mounting plate 22 and the third mounting plate 32 are on the same reference plane, thereby improving the accuracy and consistency of movement.

[0045] The working principle of this utility model is as follows: First, the robot-controlled variable-pitch embedding device is moved into the mold in the one-time forming area, and then the toothbrush handle semi-finished product is taken out by the vacuum suction cup 383 of the toothbrush contour carrier 38.

[0046] Secondly, the variable-pitch drive source 31 adjusts the spacing between each toothbrush contour carrier 38, thereby changing the spacing of each toothbrush handle semi-finished product to fit the mold in the subsequent secondary forming area, such as... Figure 5 As shown.

[0047] Then, the toothbrush handle semi-finished product is removed by the extraction robot and embedded into the mold in the secondary molding area.

[0048] After the injection molding machine finishes its work, the toothbrush handle will be removed by the extraction robot using the extraction module 20.

[0049] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
