[0023] Toilet seat production often employs semi-automatic or segmented manual assembly and testing methods. This includes the assembly of multiple components such as the shaft core, metal gasket, end cap, sealing ring, blade, and shaft housing, as well as the performance testing of the assembled product. Due to the large variety of components, high assembly requirements, and complex process connections, manual or low-level automated production methods generally suffer from problems such as low assembly efficiency, poor material transfer between processes, delayed testing, and difficulty in quality grading.

[0024] While existing technologies include assembly equipment that uses automated components such as vibratory feeders and indexing plates, most are still limited to single-station or serial operations, resulting in limited overall cycle time and poor process linkage. In particular, in the integration of multi-component assembly and product performance testing, there is a lack of systematic process integration and efficient handling and sorting design, which makes it difficult to meet the needs of modern high-efficiency manufacturing.

[0025] Therefore, this utility model proposes a toilet seat assembly production line with a clear structure, a coherent assembly process, and integrated testing and sorting, in order to improve assembly efficiency, reduce manual intervention, and improve product consistency and yield.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0027] like Figure 1-3 The toilet seat assembly line shown includes an assembly area 1 and a testing area 2. The assembly area 1 includes an assembly workbench 101, on which are connected a shaft core vibratory feeder feeding mechanism 102, a first indexing plate 104, a metal gasket vibratory feeder feeding mechanism 105, an end cap vibratory feeder feeding mechanism 106, a sealing ring vibratory feeder feeding mechanism 107, a blade vibratory feeder feeding mechanism 108, a transfer mechanism 109, a second indexing plate 110, a pallet handling mechanism 111, a shaft housing loading mechanism 113, welding equipment 114, a vision inspection mechanism 115, and multiple handling mechanisms 103. The multiple handling mechanisms 103 are respectively used to connect the shaft core vibratory feeder feeding mechanism 102 with the first indexing plate 104 and the metal gasket vibratory feeder feeding mechanism 105. 05 and the first indexing plate 104, the end cover vibratory feeder feeding mechanism 106 and the first indexing plate 104, the sealing ring vibratory feeder feeding mechanism 107 and the first indexing plate 104, the blade vibratory feeder feeding mechanism 108 and the transfer mechanism 109, the shaft housing feeding mechanism 113 and the second indexing plate 110, the second indexing plate 110 and the welding equipment 114, the welding equipment 114 and the vision inspection mechanism 115, the test area 2 includes a test workbench 201, the test workbench 201 is connected to a dual motor handling module 202, multiple test mechanisms 203, a material unloading line 204, a material unloading module 205, a transverse movement mechanism 206, and a handling mechanism 103 is set between the vision inspection mechanism 115 and the test workbench 201 to realize structural connection.

[0028] In this embodiment, the solution sets up two major functional modules, assembly area 1 and testing area 2, to realize the integrated production of the entire process from automatic material feeding, step-by-step assembly, welding, and testing of toilet seat components to functional testing and intelligent sorting. In assembly area 1, a multi-station indexing plate coordinates with multiple sets of feeding mechanisms and handling mechanisms 103 to complete the precise assembly of products. Testing area 2 uses a parallel multi-station testing structure to realize rapid testing and graded unloading of assembled products. The overall solution achieves efficient connection between various structural modules through multiple handling mechanisms 103, which significantly improves the assembly cycle time of products, reduces the frequency of manual intervention, and effectively avoids damage and deviation caused by manual transfer, ultimately achieving high-efficiency and high-consistency automated manufacturing of toilet seat components.

[0029] The first indexing plate 104 and the second indexing plate 110 are both eight-position indexing plates. The metal gasket vibratory feeder feeding mechanism 105, the end cover vibratory feeder feeding mechanism 106 and the sealing ring vibratory feeder feeding mechanism 107 are arranged at intervals along the circumference of the first indexing plate 104.

[0030] In this embodiment, both the first indexing plate 104 and the second indexing plate 110 are designed as eight-station structures, which can simultaneously complete the assembly process distribution and cycle management of multiple products. This allows different assembly steps to be carried out collaboratively in a circular arrangement. The metal gasket vibratory feeder feeding mechanism 105, the end cap vibratory feeder feeding mechanism 106, and the sealing ring vibratory feeder feeding mechanism 107 are evenly arranged around the first indexing plate 104, which helps to improve the compactness of the feeding path and the smoothness of assembly. This arrangement reduces the equipment footprint and shortens the movement path of the conveying mechanism 103, so that each assembly action can be completed in the shortest path, thereby improving the overall production cycle.

[0031] The transfer mechanism 109 is located between the first indexing plate 104 and the second indexing plate 110. The blade vibrating plate feeding mechanism 108 is connected to the transfer mechanism 109 through the handling mechanism 103 and is used to assemble the blades onto the product during the transfer process.

[0032] In this embodiment, the transfer mechanism 109 is located between the first indexing plate 104 and the second indexing plate 110 to realize the continuous transfer of products from the first stage assembly station to the second stage deep assembly station. During the transfer process, the blade vibratory feeder mechanism 108 completes the precise assembly of the blades simultaneously with the help of the transport mechanism 103. This linkage design integrates spatial paths, so that blade assembly and product transfer are completed in an integrated process, avoiding the space and time overhead required to set up a separate blade station, optimizing the system's structural compactness and improving assembly efficiency.

[0033] The pallet handling mechanism 111 is provided with a feeding position, a full pallet position and an empty pallet position. The full pallet position and the empty pallet position are respectively connected to a pallet swinging mechanism 112. The feeding position is connected to a shaft housing feeding mechanism 113, which is connected to the second indexing plate 110.

[0034] In this embodiment, the pallet handling mechanism 111 has three state areas: a feeding position, a full pallet position, and an empty pallet position. Together with the tray-swing mechanism 112 set in the full pallet position and the empty pallet position, it can realize the automatic stacking, tray-separation, and transfer functions of the shaft housing pallet. The shaft housing feeding mechanism 113 is set in the feeding position, which can feed the shaft housing coated with lubricating oil into the second indexing plate 110 with high precision, so as to achieve precise matching with the previously assembled components. The above structural design avoids the unstable cycle caused by frequent manual replenishment, while ensuring that the shaft housing components can be quickly and efficiently assembled in the oil film state, improving the sealing performance and mechanical matching accuracy of the finished product.

[0035] The number of testing mechanisms 203 is set to 5. Multiple testing mechanisms 203 are arranged in sequence along the testing workbench 201. The first 4 testing mechanisms are each provided with a discharge port 207. The discharge port 207 is opened on the surface of the testing workbench 201. The discharge line 204 is set below the 5th testing mechanism.

[0036] In this embodiment, there are a total of 5 testing mechanisms 203, which are arranged linearly along the testing workbench 201. They can perform multiple functional tests on each assembled toilet seat component in sequence, including mechanical strength test, opening and closing force test, and rebound test. The first four testing mechanisms 203 are equipped with a discharge port 207, which is used to immediately reject products that fail the test, prevent them from flowing into subsequent processes, and improve the real-time quality control of the entire line. The fifth testing mechanism 203 is connected to a discharge assembly line 204, which is used to export the finally qualified products to the classification and discharge module to realize the automatic closed loop of the entire line.

[0037] The unloading module 205 is connected to the transverse mechanism 206. The unloading end of the unloading line 204 abuts against the unloading module 205. One end of the transverse mechanism 206 is connected to multiple unloading ports 207. The unloading module 205 can move along the transverse mechanism 206 to send qualified products into the corresponding unloading port 207.

[0038] In this embodiment, the unloading module 205 is installed on the transverse mechanism 206, which can be precisely positioned and moved between different unloading ports 207. It also sorts qualified products that have passed the test according to information such as testing level and performance standards. This structure, together with the unloading assembly line 204 and the testing mechanism 203, forms a flexible and efficient finished product sorting system. It can not only realize the classified storage of qualified products, but also has the advantages of strong scalability and flexible sorting path, thereby improving the automation level of subsequent packaging or warehousing.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
