Description

Technical Field

[0001] The invention belongs to the technical field of detection of infant silicone products, and in particular relates to a quality detection device for silicone products. Background Art

[0002] Infant silicone pacifiers are baby products made of food-grade silicone material. They do not contain harmful substances such as bisphenol A, are non-toxic and harmless, and can replace traditional latex bottles to ensure the safety of infants and young children. The softness of silicone pacifiers is close to that of breast milk nipples, and the nipples can be stretched to a certain length. When the baby sucks, it can better fit the mouth, reduce discomfort, and enable the baby to suck more smoothly.

[0003] Silicone pacifiers for infants and young children are generally suitable for infants and young children aged 0 to 3 years old. Among them, there are cases where they are bitten by infants and young children aged 2 to 3 years old. In particular, infants and young children whose teeth have grown have a stronger desire to bite, and often bite or tear the silicone pacifiers. Therefore, it is very necessary to test the tension of silicone pacifiers before they leave the factory. Its traditional quality inspection still has some disadvantages: The silicone pacifier has an arc-shaped sucking part and connecting part, both of which are not convenient to lay flat for tension testing. In addition, the curvature of the two is different, so it is difficult to use one inspection tool to complete the inspection work, making quality inspection more cumbersome.

[0004] When infants and young children chew on silicone pacifiers, the connecting part will be tilted and pulled. Traditional testing platforms can hardly simulate the tilted and pulled state, and it is not convenient to detect the tension of the sucking part and the tilted state of the connecting part.

DETAILED DESCRIPTION

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0022] As a food-grade silicone product, pacifiers can be divided into feeding pacifiers and soothing pacifiers according to their uses. Fig.14 A feeding nipple shown in the figure includes an integrally formed sucking part, a connecting part, and an annular seat. The top of the sucking part is provided with a water outlet hole, from which liquid can flow out when the infant holds it in the mouth. Sometimes the nipple is bitten or pulled by the infant, which poses a great challenge to the quality of the nipple. Manufacturers generally choose to sample and conduct tension or pressure tests on nipples before they leave the factory. The tests are only carried out vertically, and the tilting and pulling situations cannot be taken into account. For this reason, the present embodiment adopts the method of alternating tension or pressure tests, which can change the inclination angle of the tension circumferentially and simplify the quality inspection steps of the nipple.

[0023] like Figure 1-Figure 14 As shown, a quality inspection device for silicone products includes a testing platform 1 and a control panel 2 fixed on the surface of the testing platform 1. A specified number of test pieces are extracted from each batch of pacifiers and placed one by one in the testing area of ​​the testing platform 1. A hydraulic system can be configured in the testing platform 1. The control panel 2 controls the hydraulic system to adjust the pressure applied to the test piece. The quality of the pacifier is judged by the integrity of its appearance after being subjected to force. If there is no crack, it is a good product, or if there is a crack, it is a defective product, and the good products and defective products are placed separately.

[0024] Refer to the attached Figure 3 , Figure 4 and Figure 6Before testing, the test piece needs to be fixed on the testing platform 1. For this purpose, the present embodiment also includes a main pressure ring 3, and a secondary pressure ring 301, a support arm 302 and a hydraulic lifting mechanism are vertically arranged outside the main pressure ring 3 in sequence. The two ends of the support arm 302 are respectively connected to the testing platform 1 and the main pressure ring 3. The secondary pressure ring 301 can be used to carry the test piece, and the control panel 2 is operated to start the hydraulic lifting mechanism to lift the secondary pressure ring 301 until it cooperates with the main pressure ring 3 to clamp the test piece, so that the sucking part and the connecting part pass through the main pressure ring 3 to prevent them from being shielded.

[0025] Refer to the attached Figure 2 , Figure 4 and Figure 6 , powered by a configured hydraulic system, the hydraulic lifting mechanism of this embodiment includes a clamping hydraulic cylinder 9 arranged outside the main pressure ring 3. Since the signal of the clamping hydraulic cylinder 9 is connected to the control panel 2, under the control of the control panel 2, the secondary pressure ring 301 can be lifted by the clamping hydraulic cylinder 9, and the cylinder rod of the clamping hydraulic cylinder 9 is extended along the central axis of the main pressure ring 3, and the end of the cylinder rod is fixed with a support fork 10 and a rubber pad 11 fixed in the middle of the support fork 10, wherein the support fork 10 is in the shape of three claws to circumferentially support the secondary pressure ring 301 to prevent it from tilting, and the rubber pad 11 can be dyed red with a front sight to guide the test piece to be centered on the secondary pressure ring 301.

[0026] Refer to the attached Figure 2 , Figure 4 and Figure 6 In order to lower the overall center of gravity of the main pressure ring 3 and the auxiliary pressure ring 301, in this embodiment, a lifting channel 12 in a cylindrical shape and fixedly connected to the clamping hydraulic cylinder 9 is fixed inside the detection platform 1. The lifting channel 12 can accommodate the auxiliary pressure ring 301 and the support fork 10, and the cylinder rod of the clamping hydraulic cylinder 9 is passed through the lifting channel 12 and fixedly connected to the middle of the lower surface of the support fork 10. A limit rod 13 fixedly connected to the outer side of the support fork 10 is slidably installed on the inner wall of the lifting channel 12 for straightening, wherein the sliding direction of the limit rod 13 is parallel to the central axis of the main pressure ring 3, so that the clamping hydraulic cylinder 9 only needs to bear the vertical load.

[0027] After the specimen is clamped, pressure testing and tension testing need to be performed separately. This embodiment takes the pressure testing first and then the tension testing as an example, as follows: Pressure detection stage: Refer to the attached Figure 1 , Figure 4 and Figure 7Since the sucking part and the connecting part have a certain roundness, the present embodiment adopts a spherical pressure head 4, and the pressure head 4 is arranged axially along the main pressure ring 3. A coupling rod 401, a pressure sensor 402 connected to the control panel 2, a guide tube 403 and a driving element are sequentially arranged along the axial direction on the side of the pressure head 4 away from the detection platform 1. The driving element is started through the control panel 2, and the coupling rod 401 and the pressure sensor 402 are pushed downward along the guide tube 403. The pressure head 4 is used to press the test piece until the pressure signal of the pressure sensor 402 reaches the specified range, or the test piece is crushed, and the pressure signal of the pressure sensor 402 becomes 0, and the pressure is stopped. At this time, the integrity of the test piece is observed to judge its quality.

[0028] Among them, the coupling rod 401 can be threadedly connected to the pressure head 4 and the pressure sensor 402, which is convenient for disassembly and assembly along the thread. The pressure head 4 of different sizes can be replaced to adapt to different types of test pieces. The pressure sensor 402 can use a U9C model tensile pressure sensor to transmit the pressure signal to the control panel 2 through a signal converter.

[0029] Refer to the attached Figure 3 , Figure 7 and Figure 8 The driving element of this embodiment includes a vertical hydraulic cylinder 14 arranged outside the pressure head 4, and the vertical hydraulic cylinder 14 is connected to the control panel 2 through a relay signal. The cylinder rod of the vertical hydraulic cylinder 14 passes through the guide tube 403 and is threadedly connected to the pressure sensor 402. Starting the vertical hydraulic cylinder 14 can drive the pressure head 4 and the pressure sensor 402 to press down. A door frame 15 fixedly connected to the linear module 504 is fixed at the bottom of the vertical hydraulic cylinder 14 by bolts to realize the suspension of the vertical hydraulic cylinder 14 and leave the space required for tension detection. At the same time, a side support rod 16 is fixed between the surface of the door frame 15 and the outer side of the guide tube 403 by bolts to form a triangular stable structure to straighten the guide tube 403, and the spokes 404 and the first blocking net 405 are both bonded to the side support rod 16, enriching the triangular stable structure and laterally supporting the pressure head 4.

[0030] Refer to the attached Figure 4 , Figure 5 and Fig.12 When the pressure head 4 breaks the test piece, the support arm 302 made of magnetic metal is used for limiting, and the magnetic sheet 303 connected to the outside of the support arm 302, the frame 304 fixedly connected to the magnetic sheet 303, and the second blocking net 305 fixed inside the frame 304 are used for blocking. In this way, the support arm 302 can not only support the secondary pressure ring 301, but also be used to prevent the test piece from flying and injuring people; Furthermore, four frames 304 and four second blocking nets 305 surround the secondary pressure ring 301, and are used to circumferentially block the specimens that are flying in the forward direction to prevent the flying parts from being missed, or the magnetic sheet 303 can be pushed away by hand to separate the frame 304 and the second blocking net 305 from the support arm 302, and the spacing can be opened for taking and placing the specimens, which will not hinder the entry and exit of the specimens and the tension detection.

[0031] Tension detection stage: The pressure head 4 needs to be lifted up and separated from the test piece first, leaving a large enough space between the test piece and the pressure head 4 for tension testing. The driving element can be translated to stagger the test piece to prevent the tension testing from being hindered.

[0032] Refer to the attached Figure 3 , Fig. 9 and Fig.10 Since the sucking part and the connecting part have a certain curvature, the present embodiment adopts a main tension head 5 and a secondary tension head 501 with a curvature, which are placed inside the test piece from the spacing of the support arm 302. A steel wire 502, a tension sensor 503 connected to the control panel 2, a support wheel 505 and a traction mechanism are sequentially arranged at one end of the main tension head 5. The traction mechanism can be controlled to pull the steel wire 502 and the tension sensor 503 along the support wheel 505 to pull the main tension head 5 and the secondary tension head 501 upward. The tension signal of the tension sensor 503 is transmitted to the control panel 2 through a signal converter. The tension sensor 503 can The LZ-LS3 tension and pressure sensor is selected. Due to the limited elastic modulus of the test piece, the main tension head 5 first applies tension to the sucking part. When the tension reaches a smaller range, the first tension test is completed. The auxiliary tension head 501 starts to stick to the connecting part and then continues to pull. Only the connecting part is subjected to the increased tension. When the tension reaches a larger range, the second tension test is completed, or the test piece is broken, the tension signal becomes 0, and then the pulling is stopped. Since the main tension head 5 and the auxiliary tension head 501 are integrated, the same inspection tool can be used to complete two tension tests in succession, and the steps are relatively simple. Further, a linear module 504 separated from the support arm 302 is disposed outside the detection platform 1, and the linear module 504 moves the support wheel 505 away from the test piece to increase the tilt angle of the tension detection, and vice versa, moves the support wheel 505 close to the test piece to reduce the tilt angle of the tension detection. The tilt angle of this embodiment is set to be within 60° of the central axis of the main pressure ring 3, and the linear module 504 and the traction mechanism are rotated around the central axis of the main pressure ring 3 within a range of 360° through the rotating mechanism disposed on the surface of the detection platform 1, so that the tension can be applied circumferentially, so that the tension detection is more comprehensive; Furthermore, once the specimen is broken, the spokes 404 on the outside of the guide tube 403 and the first barrier net 405 connected to the spokes 404 are used to limit the specimen, and the limiting effect of the support arm 302 can prevent the specimen from flying forward.

[0033] Refer to the attached Figure 1 , Figure 3 and Fig. 9 In order to facilitate the lifting and lowering of the main tension head 5 and the auxiliary tension head 501, the traction mechanism of this embodiment includes a steel cable 19 welded to the tension sensor 503, one end of the steel cable 19 is passed around the support wheel 505 and a winch 18 connected to the control panel 2 is installed. The winch 18 is started to reel in the steel cable 19, which can lift the steel wire 502 along the support wheel 505, or unwind the steel cable 19, which can lower the steel wire 502 along the support wheel 505, and will not hinder the linear module 504 from translating the support wheel 505. A base 17 connected to the rotating mechanism is fixed at the bottom of the winch 18 by bolts, so that the traction mechanism can be rotated by the rotating mechanism to change the orientation of the tension relative to the test piece.

[0034] Refer to the attached Figure 1 , Figure 3 and Fig. 9 In order to maintain the smooth operation of the linear module 504, in this embodiment, a support frame 20 connected to the rotating mechanism, a diagonal brace 21 installed inside the support frame 20, and a material storage trough 22 connected to the surface of the support frame 20 are fixed by bolts at the bottom of the linear module 504, wherein the support frame 20 and the diagonal brace 21 form a honeycomb-like stable structure for support, and the material storage trough 22 is used to place test pieces when waiting for materials, which can be subdivided into a good product area, a defective product area, an inspection area, etc.

[0035] Refer to the attached Figure 1 , Figure 3 and Fig.13 In order to rotate at a lower speed, the rotating mechanism of this embodiment includes a gear ring 23 rotatably mounted on the surface of the detection platform 1 and coaxial with the main pressure ring 3. The gear ring 23 is connected to the base 17 through the support frame 20 to drive the traction mechanism and the driving element to rotate synchronously. The teeth on the outer side of the gear ring 23 are meshed with a driving gear 24, which is driven by a servo motor 25 connected to the control panel 2 through a relay signal fixed by bolts inside the detection platform 1, so that the driving gear 24 and the gear ring 23 with a relatively small number of teeth are transmitted, and the positions of the winch 18, the linear module 504 and the support wheel 505 relative to the test piece are changed at a low speed within a range of 360°. The output end of the servo motor 25 is designed to pass through the detection platform 1 and the output end is welded to the middle of the driving gear 24 to avoid occupying the space above the detection platform 1 and conveniently avoid the support frame 20.

[0036] Refer to the attached Fig. 9 , Fig.10 and Fig.11In order to facilitate the rapid disassembly and assembly of one end of the steel wire 502 on the main force head 5, a bent bite hole 6 is opened on the outer surface of the main force head 5 of this embodiment, and a plug block 7 and a key rod 8 that can be plugged into each other are respectively provided at the two openings of the bite hole 6. The end of the key rod 8 away from the main force head 5 is welded to one end of the steel wire 502, and the key rod 8 is first passed through the hole of the sucking part from top to bottom until it is inserted into the main force head 5 along one opening of the bite hole 6, and then the plug block 7 is inserted into the other opening of the bite hole 6 and fixed with a screw, so that the concave plug block 7 locks the key rod 8, completing the connection between the steel wire 502 and the main force head 5. When the screws are unscrewed and the key rod 8 is separated from the plug block 7, the key rod 8 is used to pass through the hole of the specimen, which is convenient for separating the specimen from the steel wire 502 and preparing for the removal of the specimen.

[0037] Refer to the attached Figure 5 and Figure 6 As the main pressure ring 3 and the secondary pressure ring 301 engage with each other, part of the test piece is pressed into a ring-shaped and coaxial groove 306 on the main pressure ring 3. An extrusion ring 308 facing the groove 306 is fixed on the surface of the secondary pressure ring 301. When engaged, the test piece accurately enters the groove 306 through the extrusion part of the extrusion ring 308. When the test is completed, the main pressure ring 3 and the secondary pressure ring 301 are separated, and the inner wall of the groove 306 is integrated with a friction protrusion 307 for biting the test piece, so that the friction protrusion 307 cooperates with the groove 306 to grasp the test piece, so that the test piece is suspended in the air to avoid falling into the lifting channel 12, which is convenient for the staff to take it away by hand.

[0038] The working principle of the present invention is as follows: when working, a specified number of test pieces are firstly extracted and placed one by one in the detection area of ​​the detection platform 1, and the power is provided by the configured hydraulic system to drive the main pressure ring 3 and the auxiliary pressure ring 301 to clamp the edge of the test piece to complete the clamping.

[0039] During pressure testing, the driving unit is started through the control panel 2 to push the coupling rod 401 and the pressure sensor 402, driving the pressure head 4 to press the test piece until the pressure signal of the pressure sensor 402 reaches the specified range, or the test piece is broken and the pressure signal of the pressure sensor 402 becomes 0, then the pressure stops. At this time, the integrity of the test piece is observed to judge its quality.

[0040] When testing the tension, first pass the key rod 8 from top to bottom through the hole of the suction part until it is inserted into the main force head 5 along one opening of the bite hole 6, and then insert the plug block 7 into the other opening of the bite hole 6 and fix it with screws, so that the concave plug block 7 locks the key rod 8, completing the connection between the steel wire 502 and the main force head 5.

[0041] Restarting the winch 18 to reel in the steel cable 19 can lift the steel wire 502 along the support wheel 505, pulling the main force head 5 and the auxiliary tension head 501 upward, so that the main force head 5 first applies tension to the suction part. When the smaller range of the set tension is reached, the first tension test is completed, and the auxiliary tension head 501 begins to stick to the connecting part, and then continues to pull. Only the connecting part is subjected to the increased tension. When the larger range of the set tension is reached, the second tension test is completed, or the test piece is broken, the tension signal becomes 0, and then the traction is stopped.

[0042] At the same time, the linear module 504 moves the support wheel 505 away from the test piece to increase the inclination angle of the tension detection. Conversely, the support wheel 505 is moved closer to the test piece to reduce the inclination angle of the tension detection. The linear module 504 and the traction mechanism are rotated around the central axis of the main pressure ring 3 within a range of 360° through the rotating mechanism arranged on the surface of the detection platform 1, so that tension can be applied circumferentially.

[0043] Once the specimen is broken, the spokes 404 on the outside of the guide tube 403 and the first blocking net 405 connected to the spokes 404 are used to limit the specimen, and the limiting effect of the support arm 302 can prevent the specimen from collapsing in the forward direction.

[0044] The above is only an optional implementation of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
