Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment and relates to a toilet cover detection device used in a production line. Background Art

[0002] In recent years, the use of smart toilets has become increasingly popular. They are favored by consumers because of their diverse functions and user-friendly settings. The toilet cover, as the most important part of a smart toilet, has a large number of parts installed inside. Therefore, after assembly, it needs to undergo multiple tests before being installed on the ceramic body.

[0003] Among these tests, the air tightness test and voltage resistance test of the toilet cover are very important. The detection accuracy directly affects whether the service life of the toilet cover meets the standard. In the prior art, the air tightness test and voltage resistance test of the toilet cover are generally carried out manually. During the test, the worker needs to place the toilet cover on the test table, and then connect the air pipe assembly on the toilet cover through the external air pipe, and connect the power to the circuit board on the toilet cover through the external wire, and then repeatedly control the switch of the external air pipe and the external wire, so as to realize repeated air tightness and voltage resistance tests on the air pipe assembly and the circuit board of the toilet cover. However, in the actual operation process, the production of toilet covers is often carried out in the form of assembly line operation, and the production base is very large. The manual method of transporting and transferring the toilet covers, connecting and disconnecting the pipes and lines is a waste of human resources. At the same time, there is a certain delay in the efficiency of the air tightness test and voltage resistance test of the toilet cover, which leads to limited production efficiency of the toilet cover. Summary of the invention

[0004] The purpose of the utility model is to solve the above problems in the existing technology and to propose a toilet cover detection device for a production line. The technical problem to be solved by the utility model is: how to ensure the testing efficiency of the toilet cover while reducing labor costs.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a toilet cover detection device for a production line, the production line includes a conveyor chain and a tooling plate slidably connected to the conveyor chain, the tooling plate is provided with a fixed joint and a power connection plate, and is characterized in that a positioning mechanism capable of positioning the tooling plate on the conveyor chain is provided inside the conveyor chain, the detection device includes a power supply device for supplying power to the toilet cover and an air supply device for supplying air to the toilet cover, a first driving member with a driving end capable of extending and retracting along the width direction of the conveyor chain is provided outside the conveyor chain, the power supply device is connected to the driving end of the first driving member, a second driving member with a driving end capable of extending and retracting vertically is provided inside the conveyor chain, and the air supply device is connected to the driving end of the second driving member.

[0006] Compared with the prior art, the toilet cover detection device for the production line is innovative in that the tooling plate carrying the toilet cover is mounted on the conveying chain in a sliding connection manner. When the tooling plate slides to the detection area, the positioning mechanism can limit the tooling plate, so that the tooling plate stops on the conveying chain. After that, the driving end of the first driving member drives the power supply device to extend into the conveying chain, so that the wiring board on the tooling plate and located in the toilet cover is energized, and at the same time, the driving end of the second driving member drives the air supply device to be pushed out upward, so that the air supply device is docked with the fixed joint, thereby When the plate is in this stagnant state, the power supply device cooperates with the first driving member, and the air supply device cooperates with the second driving member, so as to realize the air tightness and voltage resistance test of the toilet cover in a mechanical and intelligent way, and by directly cooperating with the conveyor chain, there is no need for workers to spend time and effort in moving tooling plates and toilet covers, and there is no need for workers to frequently connect and disconnect various pipelines, so as to achieve the purpose of reducing labor costs. At the same time, this method is adopted for the coordination of various mechanisms to ensure the highest efficiency of air tightness and voltage resistance tests on toilet covers, thereby ensuring the production efficiency of toilet covers.

[0007] In the toilet lid detection device used in the production line, the conveyor chain includes two rails, a base plate is fixed between the two rails, the positioning mechanism includes a plurality of positioning cylinders fixed on the base plate and with the driving ends arranged vertically upward, and positioning holes are provided on the tooling plate corresponding to the driving ends of each positioning cylinder. This arrangement is used to avoid interference between the positioning mechanism and the conveyor chain and the tooling plate. Specifically, the main body of the positioning cylinder is fixed on the lower side plate of the base plate, and a clearance hole is provided on the base plate corresponding to the driving end of each positioning cylinder for the driving end of the positioning cylinder to extend out. In the process of positioning the tooling plate, each positioning cylinder drives its driving end to pass through the clearance hole and then embed into the positioning hole provided on the tooling plate, thereby achieving the positioning of the tooling plate.

[0008] In the above-mentioned toilet cover detection device for production line, the tooling plate is in the shape of a long strip, the power board is vertically fixed to one end of the tooling plate, the power supply device includes a junction box and a plurality of power posts, one end of each of the power posts is electrically connected to the junction box, and the other end can abut against the power board after the junction box is driven and extended by the first driving member. Through this setting, it is ensured that the power supply device is set more outward to avoid interference with the tooling plate during the transfer of the tooling plate through the conveyor chain, and when the preparation work for the withstand voltage test is carried out, it is only necessary to control the first driving member (specifically a cylinder, or a hydraulic cylinder) to drive its driving end, and the driving end of the first driving member drives the junction box to slide inward along the width direction of the conveyor chain, so that each power post abuts against the conductive copper sheet on the junction board, and the current transmission stability when the toilet cover is subjected to the withstand voltage test by the power supply device can be ensured.

[0009] In the toilet lid detection device for the production line, the outer end of each of the power poles is connected to an anti-lag wheel. This arrangement ensures that the friction coefficient between the power pole and the power board is smaller during power connection and power disconnection, reduces the degree of wear of the power pole, and ensures its service life. In addition, as a further technical solution, the power pole is detachably connected to the power box in a hinged manner, and a torsion spring is arranged between each power pole and the junction box to drive the power pole to tilt outward, thereby ensuring that the anti-lag wheel can be firmly pressed against the power board under the elastic action of the torsion spring, ensuring a more stable current supply.

[0010] In the toilet lid detection device for the production line, the power supply device also includes an L-shaped strip plate arranged along the width direction of the conveyor chain, one end of the strip plate is an assembly part, and the other end is a connection part. The junction box is fixed on a side plate surface of the assembly part, and a connection plate arranged vertically is fixed on the outer wall of one of the tracks. The first driving member is fixed on a side plate surface of the connection plate and the driving end is fixedly connected to the connection part. This arrangement ensures the stability of the assembly of the junction box, and one of the slide rails of the conveyor chain is used as a carrier to ensure the overall assembly stability of the power supply device. When the strip plate is driven by the first driving member, the junction box can move with the strip plate to achieve the purpose of rapid power connection or power off.

[0011] In the toilet lid detection device for the production line, a guide rod is fixedly provided on the other side plate of the assembly part along the width direction of the conveyor chain, and a guide sleeve is fixedly provided on the other side plate of the connection plate, and the guide rod is inserted into the guide sleeve. Through this arrangement, the movement direction of the strip plate and the junction box fixed on the strip plate can be guided, and the two can always slide along the width direction of the conveyor chain, and each power connection post can fully contact the junction board, so as to ensure the stability of current transmission.

[0012] In the toilet lid detection device for the production line, a mounting frame is fixed between the two rails, the second driving member is fixed on the mounting frame, the air supply device includes a movable joint and a mounting plate having a mounting channel and connected to the mounting frame in a vertical sliding manner, the movable joint is connected to the mounting plate and positioned in the mounting channel, and the driving end of the second driving member is fixedly connected to the mounting plate. Through this arrangement, under the premise of ensuring the stable installation of each component, the driving end of the second driving member (specifically a cylinder, or a hydraulic cylinder) drives the mounting plate to slide vertically on the mounting frame, and in this process, the movable joint connected to the mounting channel can move synchronously with the mounting plate, can be connected to the fixed joint when extending upward, and can be separated from the fixed joint when retracting downward, and as a further technical solution, a square opening structure is opened on the bottom plate, so that when the second driving member drives the water supply device to lift up, the movable joint is prevented from being blocked by the bottom plate.

[0013] In the toilet lid detection device for the production line, the mounting frame includes a vertically arranged plate-shaped guide portion, a T-shaped guide groove is vertically provided on the inner side plate surface of the guide portion, the mounting plate is in the shape of a long strip and bent at both ends, and both sides of the middle of the mounting plate have plug-in portions protruding outward, and the plug-in portions are slidably connected in the guide groove. Through this arrangement, the sliding direction of the mounting plate on the mounting frame can be guided, so as to avoid the direction deviation causing the movable joint connected to the mounting channel to be unable to dock with the fixed joint normally after moving upward.

[0014] In the toilet lid detection device for the production line, a connecting column is integrally formed on the upper end plate surface of the mounting plate, the mounting channel is opened in the connecting column, and the driving end of the second driving member is fixedly connected to the lower end of the mounting plate. As a specific solution, the two ends of the mounting plate are bent so that the mounting plate is C-shaped as a whole, the driving end of the driving member is fixedly connected to the lower end of the mounting plate, and an installation channel for the movable joint is opened in the connecting column at the upper end of the mounting plate, thereby ensuring that the movable joint and the fixed joint are connected and disconnected when the mounting plate is driven up and down by the driving member.

[0015] In the toilet lid detection device for the production line, the mounting frame further includes a mounting portion that is arranged horizontally and in the shape of a plate, and a limiting frame that is arranged vertically on the mounting portion and in the shape of a frame. A clearance hole is provided on the top of the limiting frame, and the movable joint is L-shaped and one end is inserted into the clearance hole. Through this partial structure, when the driving member pushes the mounting plate, so that the mounting plate drives the movable joint to move upward, the lower end of the joint can be limited by the inner wall of the top of the limiting frame, thereby avoiding excessive upward movement of the mounting plate to cause excessive interference between the movable joint and the fixed joint.

[0016] Compared with the prior art, the toilet cover detection device used in the production line has the following advantages: the tooling plate carrying the toilet cover is positioned on the conveyor chain through the positioning structure, the power supply device is driven to move and combine with the power board on the tooling plate by the first driving member, and the air supply device is driven to move and connect with the fixed joint on the tooling plate by the second driving member, so that the air tightness and voltage resistance of the toilet cover can be tested while the tooling plate carrying the toilet cover is transferred, and the various mechanisms cooperate to realize mechanical automation testing, thereby reducing labor costs and improving detection effects.
