Description

Technical Field

[0001] This invention belongs to the field of toothbrush testing technology, and particularly relates to testing equipment and toothbrush production lines. Background Technology

[0002] With rising living standards and increasingly sophisticated personal care needs, the market demand for electric toothbrushes as daily oral hygiene tools continues to grow. The core components of an electric toothbrush typically include a handle and replaceable brush heads. The handle houses the drive motor and control circuitry, while the brush head contains bristles and a transmission mechanism. During the manufacturing process, the assembly precision of the handle and brush head, as well as the final product's performance (such as noise level), directly impact user experience and product quality. Therefore, rigorous functional testing, especially noise testing, is required before electric toothbrushes leave the factory to ensure that the products meet design standards and consumer expectations.

[0003] However, the current industry practice of using a separate workstation model for the assembly and testing of electric toothbrushes: first, the handle and toothbrush head are initially assembled manually or using semi-automatic equipment, and then transferred to a separate testing station for performance testing such as noise and vibration. This model is inefficient, as the separation of assembly and testing leads to long intermediate transfer times, slow production cycles, and multiple handling may cause the workpiece to loosen or be bumped, affecting the accuracy of the tests. Summary of the Invention

[0004] The purpose of this application is to provide a testing device and a toothbrush production line, which aims to solve the problems of how to improve production efficiency and how to improve the consistency of testing.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a testing device is provided, comprising an assembly station and a first testing station along a preset direction. The testing device includes a conveying mechanism, an assembly mechanism located at the assembly station, and a testing mechanism located at the first testing station. The conveying mechanism includes a driving structure, a first loading tray for carrying a first component, and a second loading tray spaced apart from the first loading tray for carrying a second component. The driving structure drives the first loading tray and the second loading tray to slide along the preset direction. The first loading tray and the second loading tray respectively transport the first component and the second component to the assembly station. The assembly mechanism picks up the second component at the second loading tray and drives the second component to move toward the first component to assemble the second component onto the first component and form a target workpiece. The first loading tray transports the target workpiece to the first testing station, and the testing mechanism is used to test the target workpiece.

[0007] In some embodiments, the assembly mechanism includes a first movable structure and a first clamping structure connected to the first movable structure and used to clamp the second component. The first movable structure is used to drive the first clamping structure to move in three-dimensional space. The first clamping structure includes a clamping driver and two slidably disposed clamping members. The clamping members are spaced apart. The clamping driver is used to drive the two clamping members to move towards each other or away from each other.

[0008] In some embodiments, the assembly mechanism further includes a rotary driver connected between the first movable structure and the first clamping structure, the first clamping structure being connected to the output end of the rotary driver, and the rotary driver being used to drive the first clamping structure to rotate about a preset axis.

[0009] In some embodiments, the assembly mechanism further includes a first limiting structure disposed on the moving path of the first material tray. The first limiting structure includes a slidably disposed pressure plate and a lifting driver for driving the pressure plate to rise and fall. When the first material tray moves to below the pressure plate, the pressure plate presses down and contacts the first component to limit the first component.

[0010] In some embodiments, the testing equipment further includes a disassembly station located on the side of the first testing station away from the assembly station along the preset direction. The testing equipment includes a disassembly mechanism disposed at the disassembly station. The driving structure is used to drive the first material tray and the second material tray to move to the disassembly station so that the target workpiece that has passed the test at the first testing station corresponds to the disassembly mechanism. The disassembly mechanism is used to clamp the second component and drive the second component to separate from the first component. The disassembly mechanism is also used to release the second component onto the second material tray.

[0011] In some embodiments, the testing equipment further includes a second testing station located on the side of the disassembly station away from the first testing station along the preset direction. The driving structure drives the first material tray, after disassembly, to move to the second testing station, which is used to test the first component.

[0012] In some embodiments, the testing equipment further includes a material unloading station. The second testing station and the material unloading station are arranged sequentially along the preset direction. The material unloading station is equipped with a lifting and lowering transfer structure. The driving structure includes a first conveyor line and a second conveyor line located below the first conveyor line. Both the first conveyor line and the second conveyor line are used to convey the first material tray. The first conveyor line transports the first material tray to the material unloading station to unload the first component that has passed the test at the second testing station. The material transfer structure receives the unloaded first material tray at the first conveyor line and descends to dock with the second conveyor line. The second conveyor line receives the first material tray at the material transfer structure and is used to return the first material tray.

[0013] In some embodiments, the disassembly station is further provided with a defective product conveyor line, which is adjacent to the disassembly mechanism. The disassembly mechanism is also used to transfer the first component that fails the test at the first testing station to the defective product conveyor line.

[0014] In some embodiments, the disassembly mechanism includes a second movable structure, a second clamping structure connected to the second movable structure, and a third clamping structure connected to the second movable structure and spaced apart from the second clamping structure. The second clamping structure and the third clamping structure are respectively used to clamp the second component and the target workpiece. The second movable structure is used to drive the third clamping structure and the second clamping structure to move in three-dimensional space.

[0015] Secondly, a toothbrush production line is provided, including the aforementioned testing equipment.

[0016] The testing equipment provided in this application transports a first component and a second component to an assembly station, respectively. An assembly mechanism picks up the second component from the second component and drives it towards the first component, thereby assembling the second component onto the first component. The target workpiece formed by the assembly of the first and second components remains on the first component. The first component then transports the target workpiece to a first testing station, where a testing mechanism tests the target workpiece. The entire process, through the automatic coordination and operation of the assembly mechanism, testing mechanism, and conveying mechanism, significantly improves automation, reduces manual operation, integrates assembly and testing functions, and greatly enhances production efficiency. Furthermore, the assembly mechanism directly picks up the second component from the second component and assembles it onto the first component, avoiding cumulative errors caused by multiple clamping and transfer. Simultaneously, after assembly, the same component is directly transported to the first testing station from the same component, preventing loosening or offset caused by secondary clamping from affecting the test results and ensuring consistency of the test results.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 9 This application provides a testing device with an assembly station 300 and a first testing station 400 along a preset direction a. The testing device includes a conveying mechanism 10, an assembly mechanism 20 located at the assembly station 300, and a testing mechanism 900 located at the first testing station 400. The conveying mechanism 10 includes a driving structure 13, a first loading tray 11 for carrying a first component 210, and a second loading tray 12 spaced apart from the first loading tray 11 for carrying a second component 220. Both the first loading tray 11 and the second loading tray 12 slide along the preset direction a. The driving structure 13 drives the first loading tray 11 to slide along the preset direction a. The first tray 11 and the second loading tray 12 move to the assembly station 300 or the first testing station 400; the first loading tray 11 and the second loading tray 12 respectively transport the first component 210 and the second component 220 to the assembly station 300; the assembly mechanism 20 picks up the second component 220 at the second loading tray 12 and drives the second component 220 to move toward the first component 210, so as to assemble the second component 220 onto the first component 210 and form the target workpiece 200; the first loading tray 11 transports the target workpiece 200 to the first testing station 400, and the testing mechanism 900 is used to test the target workpiece 200.

[0034] It should be noted that, in this embodiment of the application, the target workpiece 200 is an electric toothbrush. The first component 210 and the second component 220 are the handle and the toothbrush head, respectively. The handle and the toothbrush head are detachably connected. The handle and the toothbrush head are the core components of the electric toothbrush. The handle has a built-in drive motor and control circuit, and the toothbrush head has bristles and a transmission structure. Understandably, the testing mechanism 900 performs noise testing on the electric toothbrush. Before testing the electric toothbrush through the testing mechanism 900, it needs to be assembled by the assembly mechanism 20. The assembly mechanism 20 assembles the handle and the toothbrush head into an electric toothbrush, thus allowing the electric toothbrush to be tested while it is operating normally.

[0035] The testing equipment provided in this application transports a first component 210 and a second component 220 to an assembly station 300, respectively, via a first loading tray 11 and a second loading tray 12. An assembly mechanism 20 picks up the second component 220 from the second loading tray 12 and drives it towards the first component 210, thereby assembling the second component 220 onto the first component 210. The target workpiece 200 formed by the assembly of the first component 210 and the second component 220 remains on the first loading tray 11. Then, the first loading tray 11 transports the target workpiece 200 to a first testing station 400, where a testing mechanism 900 performs testing on the target workpiece 200. The entire testing process is automated through the coordinated operation of the assembly mechanism 20, the testing mechanism 900, and the conveying mechanism 10, greatly improving the level of automation, reducing manual operation, integrating assembly and testing functions, and significantly improving production efficiency. Furthermore, the assembly mechanism 20 directly picks up the second component 220 from the second loading tray 12 and assembles it into the first component 210, avoiding the cumulative errors caused by multiple clamping and transfer. At the same time, after assembly, the target workpiece 200 is directly transported to the first testing station 400 from the same loading tray, avoiding the impact of loosening or offset caused by secondary clamping on the test results and ensuring the consistency of the test results.

[0036] Understandably, this application also includes a control system (not shown in the figure). The conveying mechanism 10, the assembly mechanism 20, and the testing mechanism 900 are all communicatively connected to the control system. The control system can control the conveying mechanism 10, the assembly mechanism 20, and the testing mechanism 900 to automatically coordinate and operate, thereby reducing the impact of human factors and improving production efficiency.

[0037] In addition, the testing unit 900 immediately conducts noise testing after the target workpiece 200 is assembled. This effectively simulates the actual working conditions of an electric toothbrush, such as the vibration of the brush head driven by the motor, and accurately captures abnormal noises and high-frequency noises caused by assembly gaps, poor matching of transmission structures, or defects in the components themselves. This not only improves the detection rate of defective products and avoids hidden defects that are difficult to detect in traditional static or separation tests, but also facilitates feedback and adjustment of the assembly process, controlling product quality from the source. Optionally, such as Figure 1 As shown, the first test station 400 is equipped with a loading robot 60. The loading robot 60 loads the target workpiece 200 to the test mechanism 900 for testing, and unloads the target workpiece 200 after testing, and unloads it to the first loading tray 11 for continued forward conveying.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, the assembly mechanism 20 includes a first moving structure 21 and a first clamping structure 22 connected to the first moving structure 21 and used to clamp the second component 220. The first moving structure 21 is used to drive the first clamping structure 22 to move in three-dimensional space. The first clamping structure 22 includes a clamping driver 221 and a slidably arranged clamping member 222. Two clamping members 222 are arranged at intervals. The clamping driver 221 is used to drive the two clamping members 222 to move towards each other or away from each other.

[0039] The first moving structure 21 drives the first clamping structure 22 to move in three-dimensional space, precisely moving the first clamping structure 22 above the second material tray 12 to pick up the second component 220. Then, with the same high precision, the second component 220 is moved to a position perfectly aligned with the first component 210. This three-dimensional flexible motion control ensures that the toothbrush head mates with the handle at the correct angle and position, greatly improving the success rate and accuracy of assembly. Optionally, the first moving structure 21 is a multi-axis robotic arm.

[0040] Furthermore, the first clamping structure 22 employs a scheme where two slidingly arranged clamping members 222 are driven by a clamping driver 221 to move towards or away from each other, thereby clamping and releasing the second component 220. Precise and adjustable control of the clamping force can be achieved through precise control of the output of the clamping driver 221, which helps protect toothbrush heads with delicate surfaces or fragile materials, preventing damage to the second component 220 due to excessive clamping force or detachment due to insufficient force. Moreover, the distance between the two clamping members 222 is variable, thus accommodating second components 220 of different sizes and models, improving the adaptability of the assembly mechanism 20. Optionally, the clamping driver 221 can be a cylinder or a motor.

[0041] In some embodiments, the assembly mechanism 20 further includes a rotary driver 23 connected between the first moving structure 21 and the first clamping structure 22. The first clamping structure 22 is connected to the output end of the rotary driver 23, and the rotary driver 23 drives the first clamping structure 22 to rotate around a preset direction b. The rotary driver 23 drives the first clamping structure 22 to rotate around the preset direction b, increasing the rotational degree of freedom of the second component 220. This allows the first clamping structure 22 to accurately adjust the angle and posture of the second component 220 in the horizontal or vertical plane, based on the three-dimensional movement and positioning. This ensures that the toothbrush head can achieve perfect circumferential alignment with the interface on the handle at the moment of final assembly, avoiding improper assembly and improving the quality of assembly.

[0042] In some embodiments, such as Figure 2 and Figure 4 As shown, the assembly mechanism 20 also includes a first limiting structure 24, which is located in the moving path of the first material tray 11. The first limiting structure 24 includes a slidingly disposed pressure plate 242 and a lifting driver 241 for driving the pressure plate 242 to rise and fall. When the first material tray 11 moves to below the pressure plate 242, the pressure plate 242 presses down and contacts the first component 210 to limit the first component 210.

[0043] Understandably, during the assembly process, the first component 210 is supported only by the first loading tray 11 and is in a relatively free state. When the assembly mechanism 20 presses the second component 220 onto the first component 210, a reverse force is generated, which can easily cause the first component 210 to shift or lift on the first loading tray 11, resulting in assembly misalignment. However, by setting the pressure plate 242 to press down directly and contact the first component 210, it provides a reliable positioning reference from above, preventing the first component 210 from shifting during assembly and ensuring that each assembly operation is completed in the same precise position, greatly improving the consistency and success rate of assembly. Optionally, the shape of the contact surface between the pressure plate 242 and the first component 210 is adapted to the outer contour shape of the first component 210. Specifically, the first component 210 is a cylindrical rod, and the contact surface between the pressure plate 242 and the first component 210 is an arc-shaped surface.

[0044] Optionally, such as Figure 4 As shown, the assembly mechanism 20 also includes a blocking structure located on the moving path of the first material tray 11. The blocking structure includes a stop 71 that slides vertically and a moving driver 72 that drives the stop 71 to rise and fall. When the assembly position is reached, the moving driver 72 drives the stop 71 to rise and block the first material tray 11, causing the first material tray 11 to stop moving forward. Then the assembly mechanism 20 starts the assembly operation. By setting the blocking structure, the first material tray 11 can be prevented from moving excessively, thereby improving the consistency of the assembly of the target workpiece 200.

[0045] In some embodiments, such as Figure 5 As shown, the testing equipment also has a disassembly station 500, which is located on the side of the first testing station 400 away from the assembly station 300 along a preset direction a. The testing equipment includes a disassembly mechanism 30 located at the disassembly station 500. The drive structure 13 is used to drive the first material tray 11 and the second material tray 12 to move to the disassembly station 500 so that the target workpiece 200 that has passed the test at the first testing station 400 corresponds to the disassembly mechanism 30. The disassembly mechanism 30 is used to clamp the second component 220 and drive the second component 220 to separate from the first component 210. The disassembly mechanism 30 is also used to release the second component 220 onto the second material tray 12.

[0046] Understandably, the first loading tray 11 and the second loading tray 12 can move sequentially between the assembly station 300, the first testing station 400 and the disassembly station 500 under the drive of the drive structure 13. After the first testing station 400 passes the test, the target workpiece 200 is automatically transported to the disassembly station 500 for separation. The separated first component 210 can flow to the next station, while the second component 220 can be recycled, forming a continuous production cycle, eliminating the need for manual intervention, thereby significantly improving the overall equipment utilization and production efficiency.

[0047] In addition, the disassembly mechanism 30 precisely releases the separated second component 220 back to the second loading tray 12, while the first component 210 remains on the first loading tray 11. This process automatically completes the classification and placement of different components in qualified products, avoiding the risk of confusion between different components and mixing of different models of parts that may be caused by manual operation, and ensuring the rigor of the production process and the traceability of product quality.

[0048] In some embodiments, such as Figure 8 As shown, the testing equipment also includes a second testing station 600, located on the side of the disassembly station 500 away from the first testing station 400 along a preset direction a. The drive structure 13 drives the disassembled first loading tray 11 to move to the second testing station 600. The second testing station 600 is used to test the first component 210. Specifically, the second testing station 600 is equipped with a loading robot 60 and an airtightness testing device (not shown). The loading robot 60 loads the first component 210 onto the airtightness testing device and unloads the tested first component 210 onto the first loading tray 11 for further forward transport. The airtightness testing device is used to test the airtightness of the first component 210. Airtightness defects are a fatal flaw in electric toothbrush products, leading to internal circuit corrosion, functional failure, and even safety hazards. Therefore, airtightness testing reduces the failure rate and safety risks during product use.

[0049] In this embodiment, the handle first undergoes a functional performance test at the first testing station 400, assembled with the toothbrush head, to verify its working status. After separation, it undergoes a body airtightness test at the second testing station 600. This ensures that only handles that pass both tests are recycled and reused, greatly improving the reliability of the manufactured products. Furthermore, integrating the airtightness test into the automated production line as part of the cycle achieves seamless connection of the testing process. The handle can be automatically tested after disassembly without going off-line or re-clamping, improving the detection coverage while ensuring production cycle time.

[0050] In some embodiments, such as Figure 6 As shown, the disassembly station 500 is also equipped with a defective product conveyor line 50, which is adjacent to the disassembly mechanism 30. The disassembly mechanism 30 is also used to transfer the first component 210 that failed the test at the first test station 400 to the defective product conveyor line 50. Understandably, when the test mechanism 900 identifies a defective product, the disassembly mechanism 30 moves the first component 210 obtained from disassembling the defective target workpiece 200 to the defective product conveyor line 50, achieving rigid isolation between qualified and unqualified products on the production line, fundamentally eliminating the risk of defective products being mistakenly judged as qualified products and allowed to flow out or continue processing.

[0051] In some embodiments, such as Figure 6 and Figure 7 As shown, the disassembly mechanism 30 includes a second moving structure 31, a second clamping structure 32 connected to the second moving structure 31, and a third clamping structure 33 connected to the second moving structure 31 and spaced apart from the second clamping structure 32. The second clamping structure 32 and the third clamping structure 33 are used to clamp the first component 210 and the second component 220, respectively. The second moving structure 31 is used to drive the third clamping structure 33 and the second clamping structure 32 to move in three-dimensional space. Optionally, the second moving structure 31 is a multi-axis robotic arm. The specific structures of the second clamping structure 32 and the third clamping structure 33 are similar to those of the first clamping structure 22, and their specific structures will not be described in detail here.

[0052] Understandably, the second clamping structure 32 and the third clamping structure 33 are arranged in parallel and driven by the same second moving structure 31, allowing the second moving structure 31 to simultaneously complete two operations during a single movement, greatly shortening the workstation operation time. Furthermore, integrating two sets of clamping structures with different functions onto the same moving module achieves a high degree of functional integration, saves equipment space, optimizes the workstation layout, and makes the overall structure more compact.

[0053] In some embodiments, the disassembly mechanism 30 includes a second limiting structure 34. The second limiting structure 34 is similar in principle and specific structure to the first limiting structure 24. The second limiting structure 34 is located on the moving path of the first loading tray 11. During the disassembly of the target workpiece 200, the second limiting structure 34 presses down directly through the pressure plate and contacts the first component 210, which is equivalent to providing a reliable positioning reference from above. This avoids displacement of the first component 210 when the second component 220 separates from the first component 210, greatly improving the consistency and success rate of disassembly.

[0054] In some embodiments, the disassembly mechanism 30 further includes a lifting structure 35, two of which are spaced apart and respectively located on the moving paths of the first material tray 11 and the second material tray 12. Understandably, the lifting structure 35 includes a vertically slidable support plate, which is liftable to raise either the first material tray 11 or the second material tray 12 to a preset height. This facilitates docking of the first material tray 11 and the second material tray 12 with the third clamping structure 33 and the second clamping structure 32, respectively, improving the convenience of the second clamping structure 32 clamping the second component 220 and the third clamping structure 33 clamping the target workpiece 200.

[0055] In some embodiments, such as Figure 8 and Figure 9 As shown, the testing equipment also includes a material unloading station 800, a second testing station 600, and a material unloading station 800 arranged sequentially along a preset direction a. The material unloading station 800 is equipped with a lifting and lowering material transfer structure 41. The drive structure 13 includes a first conveyor line 131 and a second conveyor line 132 located below the first conveyor line 131. Both the first conveyor line 131 and the second conveyor line 132 are used to transport the first material tray 11. The first conveyor line 131 transports the first material tray 11 to the material unloading station 800 to unload the first component 210 that has passed the test at the second testing station 600. The material transfer structure 41 receives the unloaded first material tray 11 at the first conveyor line 131 and descends to dock with the second conveyor line 132. The second conveyor line 132 receives the first material tray 11 at the material transfer structure 41 and is used to return the first material tray 11. Optionally, the material transfer structure 41 is connected to the lifting cylinder 42, which is used to drive the material transfer structure 41 to move up and down.

[0056] In the embodiments of this application, such as Figure 5As shown, for the second loading tray 12, referring to the conveying method of the first loading tray 11, the drive structure 13 is also provided with upper and lower conveyor lines and a material transfer structure 41. The upper conveyor line transports the second loading tray 12 to the disassembly station 500. The disassembly mechanism 30 accurately releases the separated second component 220 back to the second loading tray 12. The material transfer structure 41 rises to the upper conveyor line to receive the second loading tray 12, and then descends to dock with the lower conveyor line. The lower conveyor line receives the second loading tray 12 at the material transfer structure 41. The lower conveyor line is used to return the second loading tray 12, thereby forming a continuous production cycle.

[0057] Understandably, such as Figure 5 As shown, the testing equipment also includes a loading station 700. The loading station 700, assembly station 300, first testing station 400, disassembly station 500, second testing station 600, and unloading station 800 are arranged sequentially along a preset direction a. The loading station 700 is used to load the first component 210 and the second component 220. After the first loading tray 11 unloads the first component 210 that has passed the test at the second testing station 600 at the unloading station 800, the transfer structure 41 receives the unloaded first loading tray 11 at the first conveyor line 131 and descends to dock with the second conveyor line 132. The second conveyor line 132 receives the first loading tray 11 at the transfer structure 41 and transports the first component 210 from the unloading station 800 to the loading station 700, thereby realizing the return of the first component 210. Optionally, the material transfer structure 41 is a conveyor line. By reversing the conveyor line motor, the conveyor line can transport in the same direction as the first conveyor line 131, thereby conveying the first component 210 to the second conveyor line 132.

[0058] The present invention also proposes a toothbrush production line, which includes testing equipment. The specific structure of the testing equipment is as described in the above embodiments. Since this toothbrush production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0059] In summary, the testing equipment provided in this application transports the first component 210 and the second component 220 to the assembly station 300, respectively, using the first loading tray 11 and the second loading tray 12. The assembly mechanism 20 picks up the second component 220 from the second loading tray 12 and drives the second component 220 toward the first component 210, thereby assembling the second component 220 onto the first component 210. The target workpiece 200 formed by the assembly of the first component 210 and the second component 220 remains on the first loading tray 11. Then, the first loading tray 11 transports the target workpiece 200 to the first testing station 400, where the testing mechanism 900 is used to test the target workpiece 200. The entire testing process is automated through the coordinated operation of the assembly mechanism 20, the testing mechanism 900, and the conveying mechanism 10, greatly improving the level of automation, reducing manual operation, integrating assembly and testing functions, and significantly improving production efficiency. Furthermore, the assembly mechanism 20 directly picks up the second component 220 from the second loading tray 12 and assembles it into the first component 210, avoiding the cumulative errors caused by multiple clamping and transfer. After assembly, the target workpiece 200 is directly transported to the first testing station 400 from the same loading tray, avoiding the impact of loosening or offset caused by secondary clamping on the test results and ensuring the consistency of the test results.

[0060] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
