Description

Technical Field

[0001] The present invention relates to the technical field of toy detection, and specifically provides a pressure resistance detection device and method for a doll model toy. Background Art

[0002] A doll model toy is a toy made based on a human figure image, usually having certain collection value, decorative value and entertainment value. With the continuous development of the doll model toy market, consumers' requirements for the quality and safety of toys are increasing day by day. During the production, transportation and children's play of doll model toys, they may suffer various pressures and impacts. For example, during the production process, the toy may be squeezed by assembly equipment; during transportation, it may bear different degrees of pressure due to the stacking of goods, and may also be dropped during handling and loading / unloading. And when children play with the toy, they may accidentally drop the toy or collide it with other objects.

[0003] Existing toy pressure resistance detection devices often have some defects. The fixture structures of some devices are simple and cannot adaptively apply uniform pressure according to the complex shape of the doll model toy, which easily leads to inaccurate test results and cannot truly reflect the pressure resistance performance of the toy in actual use. Moreover, during the pressure detection process, experiments are carried out by extrusion, and due to the irregular shape of the toy, only the material of the toy can be detected, and it is difficult to comprehensively detect the impact resistance performance of the toy. The present invention provides a pressure resistance detection device and method for a doll model toy. Summary of the Invention

[0004] In view of the above deficiencies existing in the prior art, the present invention provides a pressure resistance detection device and method for a doll model toy, which can more accurately, comprehensively and safely and conveniently detect the pressure resistance performance of the doll model toy.

[0005] The present invention provides the following technical solutions: A pressure resistance detection device for a doll model toy, including a base and four guide columns installed on the base, and the four guide columns are connected to a top seat. An A flexible fixture is arranged inside the base, and the flexible fixture adjusts its height through a lifting device so that the ejector pin of the A flexible fixture extends out of the base;

[0006] A slidable positioning frame is arranged on the four guide columns, and a hydraulic cylinder for pushing the positioning frame to slide on the guide columns is installed inside the top seat;

[0007] A slidable movable seat is arranged on the four guide columns. The movable seat includes two support seats sliding on the guide columns, and the middle parts of the two support seats are hinged to a plate seat through an axle core. Positioning members for supporting the plate seat are arranged at both ends of the two support seats. A B flexible fixture and an elastic absorber are respectively installed at the upper and lower ends of the plate seat;

[0008] On both sides of the bottom end of the positioning frame, A electromagnets are embedded, and iron sheets are installed at the top ends of the two support seats. The positioning frame adsorbs the movable seat through the A electromagnets and drives it to adjust the height. When the B flexible fixture faces downward, the A electromagnets are powered off, and the movable seat drops, enabling the B flexible fixture to conduct pressure tests on the doll model toy on the A flexible fixture from different heights.

[0009] A number of groups of elastic accelerators are provided on the positioning frame. The elastic accelerators apply initial kinetic energy to the movable seat. A slidable support frame is provided on the four guide posts. The support frame intercepts the falling movable seat. When the elastic adsorbent faces downward, the elastic adsorbent adsorbs the doll model toy. When the A electromagnets are powered off, the elastic accelerators apply initial kinetic energy to the falling movable seat and the doll model toy. The support frame intercepts the movable seat, enabling the doll model toy to conduct impact experiments under different kinetic energies.

[0010] Preferably, the positioning member includes a rectangular frame installed on the support seat and a number of groups of fixed sleeves installed inside the rectangular frame. A return spring and a pressing plate are provided inside the fixed sleeve. A positioning column extending from the rectangular frame is installed on the pressing plate, and the positioning column is slidably connected to the rectangular frame. All the positioning columns are connected to a U-shaped push plate, and the inner side of the U-shaped push plate is slidably connected to both ends of the rectangular frame. There are gaps at the four corners of the plate seat, and B electromagnets are embedded inside the gaps. When the B electromagnets are powered off, the plate seat can be rotated to adjust the positions of the upper and lower surfaces, and the iron-made U-shaped push plate is adsorbed by the B electromagnets to keep the plate seat stable.

[0011] Preferably, the elastic adsorbent includes a bottom plate and an electromagnetic chuck installed on the bottom plate. A housing is installed on the bottom plate. A number of groups of slidable movable columns are provided inside the housing, and each movable column extends out of the hole at the top of the housing. A locking structure for position locking is provided on each movable column. A magnet block is installed at the bottom end of each movable column, and a pneumatic suction nozzle is installed on each movable column. When the elastic adsorbent moves downward and contacts the doll model toy, the electromagnetic chuck is powered off. The pneumatic suction nozzles on the movable columns contact the doll model toy first and drive the movable columns to move backward, enabling the doll model toy to be adhesively adsorbed by the pneumatic suction nozzles on a number of groups of movable columns. The position of the movable column is locked by the locking structure to conduct an impact experiment. When the electromagnetic chuck is powered on, the magnetism of the electromagnetic chuck is the same as that of the magnet block to generate a repulsive force, causing the magnet block to drive the movable column to reset.

[0012] Preferably, the locking structure includes several groups of locking sleeves installed inside the outer shell. The several groups of locking sleeves are arranged on each movable column, and the movable column is slidably connected to the inner side of the locking sleeve. The locking sleeve is designed to be hollow. The several groups of locking sleeves are interconnected through pipes, and the several groups of locking sleeves are connected to the positioning cylinder through pipes. A slidable piston is provided inside the positioning cylinder, and the piston is connected through a connecting column. The connecting column extends out of the positioning cylinder and is slidably connected to it. There is liquid in the locking sleeve, the piston and the pipes connecting them. By squeezing the inside of the positioning cylinder with the piston, the liquid pressure increases, causing the inner side of the locking sleeve to expand and deform to clamp the movable column, and the connecting column is driven by an electric cylinder.

[0013] Preferably, the inner side of the locking sleeve is made of flexible metal. When the liquid pressure inside the locking sleeve increases, it will squeeze the inner side of the locking sleeve to deform, thereby clamping the movable column.

[0014] Preferably, the elastic accelerator includes a circular tube passing through the positioning frame. At the upper and lower ends of the circular tube, an A positioning ring and a B positioning ring are respectively installed. A strong spring is provided inside the circular tube. Below the strong spring, there is a slidable A movable block. The bottom end of the A movable block is installed with a movable column, and the bottom end of the movable column passes through the B positioning ring and abuts against the movable seat. Above the strong spring, there is a slidable B movable block. An electric cylinder is installed on the A positioning ring, and the moving end of the electric cylinder is connected to the B movable block through the A positioning ring. By adjusting the position of the B movable block with the electric cylinder, the compression amount of the strong spring is adjusted to control the kinetic energy applied to the movable seat.

[0015] Preferably, a C electromagnet is embedded on the support frame, and a corresponding D electromagnet is embedded at the bottom of the movable seat. And there is a bolt for locking on the support frame. When the support frame is moved to a specified height and the movable seat falls, the C electromagnet and the D electromagnet have the same magnetic poles, so that the movable seat is intercepted under the repulsive force, and the doll model toy continues to fall.

[0016] Preferably, a protective wall is installed at the top end of the base, and the protective wall is made of a transparent material. A window door is hinged on the protective wall.

[0017] A method for detecting the pressure resistance of a doll model toy is as follows:

[0018] S1. During the pressure test, the lifting device inside the base drives the A flexible fixture to rise, so that the ejector pin of the A flexible fixture is exported from the base, and the doll model toy is placed on it. Then, the support frame is moved to the base, and the positioning frame is driven to move by the hydraulic cylinder. And the A electromagnet is powered on, so that the movable seat is adsorbed at the bottom end of the positioning frame. The position of the movable seat is adjusted by the hydraulic cylinder, so that the B flexible fixture on the movable seat moves down and contacts the doll model toy during the process. Under pressure, the doll model toy is fitted with the ejector pins on the A flexible fixture and the B flexible fixture. Then, the ejector pins on the A flexible fixture and the B flexible fixture are locked.

[0019] S2. The hydraulic cylinder drives the movable seat to be released from different heights. After the A electromagnet is powered off, the movable seat falls to conduct a pressure test on the toy on the A flexible fixture. At the same time, the elastic accelerator can provide initial kinetic energy for the falling of the movable seat to strengthen the kinetic energy of the pressure test.

[0020] S3. In the impact experiment, first, the ejector pin of the A flexible fixture is retracted at the top of the base, and the support frame is moved to a specified position. The doll model toy is placed on the base. The hydraulic cylinder drives the movable seat to move down, and the elastic adsorber picks up the doll model toy. Then, the hydraulic cylinder drives the movable seat to move up, and the elastic adsorber releases the doll model toy, so that the doll model toy falls from different heights for the impact experiment.

[0021] S4. If the height of the impact experiment is not enough, the A electromagnet is powered off, and the elastic adsorber releases the doll model toy. The elastic accelerator applies initial kinetic energy to the movable seat, so that the movable seat and the doll model toy accelerate to fall. The movable seat is blocked by the support frame, and the doll model toy falls on the base to strengthen the kinetic energy of the impact experiment.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) When the A flexible fixture and the B flexible fixture contact the doll model toy, they can adaptively deform according to its shape. This means that during the pressure test, the fixture can closely fit the toy surface, ensuring uniform pressure application, avoiding damage to the doll model toy caused by excessive local pressure, and thus being able to more accurately detect the pressure resistance performance of the toy under different pressures.

[0024] (2) The height of the movable seat can be adjusted by the hydraulic cylinder, and the rising and releasing operations of the movable seat can be achieved. At the same time, combined with the elastic accelerator, initial kinetic energy can be applied to the movable seat during its falling process to simulate different pressure impact situations, such as simulating different degrees of collision, extrusion, etc. that the toy may suffer during transportation, making the pressure resistance test more comprehensive and realistic.

[0025] (3) In the impact experiment, the dropping height of the doll model toy can be changed by adjusting the stroke of the hydraulic cylinder to simulate different dropping scenarios. Moreover, if the height of the impact experiment is not sufficient, the movable seat and the doll model toy can be given initial kinetic energy by an elastic accelerator, and the repulsive force generated by the C electromagnet on the support frame and the D electromagnet at the bottom of the movable seat can be used to separate the doll model toy from the movable seat, further enhancing the kinetic energy of the impact experiment, so as to more comprehensively detect the impact resistance of the doll model toy under different energy impacts and better simulate various dropping situations that the toy may encounter during actual use or transportation.

[0026] (4) The design of the elastic adsorption component enables the doll model toy to be firmly fixed on the elastic adsorption component when adsorbed. When the elastic adsorption component contacts the doll model toy, the electromagnetic chuck is powered off and the pneumatic suction nozzle works to adsorb the doll model toy. At the same time, the locking structure locks the position of the movable column to ensure that the toy will not accidentally fall off when it is lifted to a certain height for the impact experiment, guaranteeing the safety and accuracy of the experiment.

Detailed implementation manners

[0041] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. To keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and known components are omitted to avoid unnecessarily obscuring the concepts of the present invention.

[0042] Please refer to Figure 1 and Figure 2 , a pressure resistance detection device for a doll model toy. This device mainly includes components such as a base 1, guide posts 2, A flexible fixture 3, positioning frame 4, hydraulic cylinder 5, movable seat 6, elastic accelerator 7, support frame 8, protective wall 9, window door 10, etc.

[0043] The base 1 serves as the basic support structure of the entire device and is made of a strong and stable metal material, providing a stable installation platform for other components. Four guide posts 2 are installed on the base 1. The guide posts 2 are made of high-strength alloy steel material to ensure that they have sufficient rigidity and wear resistance to support components such as the positioning frame 4, movable seat 6, and support frame 8 to slide stably on it. The tops of the four guide posts 2 are firmly connected to the top seat 14, and the top seat 14 is also made of metal material to ensure the structural stability of the entire device.

[0044] Inside the base 1, there is a flexible fixture A 3, which cooperates with the lifting device. The lifting device can adopt common lifting methods such as electric telescopic rods or hydraulic lifting mechanisms. When pressure testing is required, the lifting device is started to drive the flexible fixture A 3 to rise, so that the ejector pin of the flexible fixture A 3 extends out of the base 1, in order to place the doll model toy and perform subsequent pressure testing operations.

[0045] There is a slidable positioning frame 4 sleeved on the four guide posts 2, and the hydraulic cylinder 5 installed in the top seat 14 is connected to the positioning frame 4. The telescopic movement of the piston rod of the hydraulic cylinder 5 can push the positioning frame 4 to slide up and down along the guide posts 2, so as to accurately adjust the position of the lower movable seat 6.

[0046] Refer to Figure 5 、 Figure 6 and Figure 7 As shown in

[0047] The structure of the movable seat 6 is relatively unique. It includes two support seats 61 that slide on the guide posts 2. The middle parts of these two support seats 61 are hinged to the plate seat 62 through an axle core, so that the plate seat 62 can rotate flexibly relative to the support seat 61. Positioning members 63 are provided at both ends of the two support seats 61;

[0048] Refer to Figure 8 As shown in

[0049] The specific structure of the positioning member 63 is as follows:

[0050] Refer toFigure 9 The elastic adsorption component 65 includes a bottom plate 651 and an electromagnetic chuck 652 mounted on the bottom plate 651. The bottom plate 651 is made of a metal material and provides an installation basis for other components. The electromagnetic chuck 652 is connected to a power supply and a control system, and its on and off states are controlled by the control system.

[0051] A housing 653 is mounted on the bottom plate 651. The housing 653 is made of a plastic material and has a light weight and good insulation performance. Inside the housing 653, there are several sets of slidable movable columns 654. The movable columns 654 are made of a metal material, and their surfaces are smooth-treated to reduce the friction with the housing 653. Each movable column 654 extends out from a hole at the top of the housing 653, and a locking structure 655 for position locking is provided on each movable column 654.

[0052] Refer to Figure 10 、 Figure 11 and Figure 12 The locking structure 655 includes several sets of locking sleeves 6551 mounted inside the housing 653. The inner side of the locking sleeve 6551 is made of a flexible metal material, such as copper alloy, etc., which has good wear resistance and deformability. Several sets of locking sleeves 6551 are arranged on each movable column 654, and the movable column 654 is slidably connected to the inner side of the locking sleeve 6551. The locking sleeve 6551 is of a hollow design, and several sets of locking sleeves 6551 are interconnected through pipes, and several sets of locking sleeves 6551 are connected to a positioning cylinder 6552 through pipes. Inside the positioning cylinder 6552, there is a slidable piston 6553, and the piston 6553 is connected by a connecting column 6554. The connecting column 6554 extends out from the positioning cylinder 6552 and is slidably connected to it. There is a liquid, such as hydraulic oil, etc., in the locking sleeve 6551, the piston 6553 and their connected pipes. The piston 6553 is driven by an electric cylinder connected by the connecting column 6554 to slide inside the positioning cylinder 6552, squeezing the liquid inside the positioning cylinder 6552, increasing the liquid pressure, so that the inner side of the locking sleeve 6551 expands and deforms to clamp the movable column 654, realizing the locking of the position of the movable column 654.

[0053] A magnet block 656 is installed at the bottom end of each movable column 654, and a pneumatic suction nozzle 657 is installed on each movable column 654. The pneumatic suction nozzle 657 is connected to an external air source, and the on / off of the air source is controlled by a control system. When the elastic suction attachment 65 moves down to contact the doll model toy, the electromagnetic chuck 652 is powered off. The pneumatic suction nozzle 657 on the movable column 654 contacts the doll model toy first and drives the movable column 654 to move backward, so that the doll model toy is adhered and adsorbed by the pneumatic suction nozzles 657 on several groups of movable columns 654. At the same time, the control system controls the electric cylinder to drive the connecting column 6554, so that the piston 6553 squeezes the liquid, and the locking sleeve 6551 clamps the movable column 654 to fix the position of the movable column 654 for the impact test. When the electromagnetic chuck 652 is powered on, the magnetism of the electromagnetic chuck 652 is the same as that of the magnet block 656 to generate a repulsive force, so that the magnet block 656 drives the movable column 654 to reset and prepare for the next operation.

[0054] On both sides of the bottom end of the positioning frame 4, A electromagnets 13 are embedded, and iron sheets are installed at the top ends of the two support seats 61 at corresponding positions. During the pressure test, the A electromagnets 13 are powered on and can adsorb the movable seat 6. The positioning frame 4 is driven to move by the hydraulic cylinder 5, so as to adjust the height of the movable seat 6, so that the B flexible fixture 64 can accurately contact the doll model toy and apply pressure. When pressure tests at different heights are required, the A electromagnets 13 are powered off, and the movable seat 6 drops, so that the B flexible fixture 64 performs pressure tests on the doll model toy on the A flexible fixture 3 from different heights. At the same time, several groups of elastic accelerators 7 provided on the positioning frame 4 can apply initial kinetic energy to the movable seat 6 to enhance the effect of the pressure test.

[0055] Several groups of elastic accelerators 7 are provided on the positioning frame 4. The elastic accelerators 7 are used to apply initial kinetic energy to the movable seat 6 to enhance the effects of the pressure test and the impact test.

[0056] Refer to Figure 13 , the elastic accelerator 7 includes a circular tube 71 penetrating the positioning frame 4. The circular tube 71 is made of a high-strength steel pipe and has good rigidity and wear resistance. An A positioning ring 72 and a B positioning ring 73 are respectively installed at the upper and lower ends of the circular tube 71. The A positioning ring 72 and the B positioning ring 73 are used to fix the position of the circular tube 71 and play a limiting role on the internal components. A strong spring 74 is provided inside the circular tube 71. An A movable block 75 that can slide is provided below the strong spring 74. An activity column 76 is installed at the bottom end of the A movable block 75, and the bottom end of the activity column 76 passes through the B positioning ring 73 and abuts against the movable seat ⑥. A B movable block 77 that can slide is provided above the strong spring 74. An electric cylinder 78 is installed on the A positioning ring 72, and the moving end of the electric cylinder 78 is connected to the B movable block 77 through the A positioning ring 72.

[0057] During the working process, the telescopic movement of the electric cylinder 78 is controlled by the control system to adjust the position of the B movable block 77, thereby adjusting the compression amount of the strong spring 74. When kinetic energy needs to be applied to the movable seat 6, the control system controls the electric cylinder 78 to contract, causing the strong spring 74 to compress and store elastic potential energy. When the movable seat 6 falls, the A electromagnet 13 is powered off, and the strong spring 74 releases elastic potential energy, pushing the A movable block 75 and the movable column 76 downward to apply initial kinetic energy to the movable seat 6, causing the movable seat 6 to accelerate downward, thereby strengthening the kinetic energy of the pressure test or the impact test.

[0058] The support frame 8 is arranged on the four guide columns 2 and is slidable. The support frame 8 is embedded with a C electromagnet 81, and the corresponding D electromagnet 82 is embedded at the bottom position of the movable seat 6. A bolt 83 for locking is also installed on the support frame 8. During the impact test, the support frame 8 is moved to a specified height and locked by the bolt 83. When the movable seat 6 is falling, the C electromagnet 81 and the D electromagnet 82 have the same magnetic poles, generating a repulsive force, causing the movable seat 6 to be intercepted under the action of the repulsive force, while the doll model toy continues to fall, thereby realizing the impact test of the doll model toy at different heights. At the same time, the initial kinetic energy can also be applied to the falling movable seat 6 and the doll model toy through the elastic accelerator 7 to further strengthen the kinetic energy of the impact test and more comprehensively detect the impact resistance of the doll model toy.

[0059] A protective wall 9 is installed at the top end of the base 1. The protective wall 9 is made of a high-strength transparent material, such as an acrylic board, etc., which can prevent the doll model toy from accidentally popping out and causing harm to the operator during the test. At the same time, a window door 10 is hinged on the protective wall 9, which is convenient for the operator to place and take out the doll model toy and observe and maintain the interior of the device.

[0060] A method for detecting the pressure resistance of a doll model toy is as follows:

[0061] When performing the pressure test: (Refer to Figure 3 and Figure 4 );

[0062] S1. The lifting device inside the base 1 drives the A flexible fixture 3 to rise, so that the ejector pin of the A flexible fixture 3 is led out of the base 1, and the doll model toy is placed on the ejector pin of the A flexible fixture 3 to ensure that the doll model toy is placed stably.

[0063] S2. The support frame 8 is moved to a suitable position on the base 1 through the adjusting bolt 83 and fixed.

[0064] S3. The hydraulic cylinder 5 is started through the control system. The hydraulic cylinder 5 drives the positioning frame 4 to move downward along the guide column 2. At the same time, the A electromagnet 13 is powered on to generate a strong magnetic field, adsorbing the movable seat 6 at the bottom end of the positioning frame 4, so that the movable seat 6 moves downward together with the positioning frame 4.

[0065] S3. When the B flexible fixture 64 on the movable seat 6 moves downward and contacts the doll model toy, under the action of pressure, the doll model toy is closely fitted with the ejector pins on the A flexible fixture 3 and the B flexible fixture 64. At this time, the ejector pins on the A flexible fixture 3 and the B flexible fixture 64 are locked through the control system, for example, by using an electromagnetic lock or a mechanical lock, etc., to ensure the relative position between the ejector pins and the doll model toy is fixed, so as to perform an accurate pressure test.

[0066] S4. The hydraulic cylinder 5 drives the movable seat 6 to rise to a certain height and then releases. After the A electromagnet 13 is powered off, the movable seat 6 falls under the action of gravity to perform a pressure test on the toy on the A flexible fixture 3. At the same time, during the falling process of the movable seat 6, the electric cylinder 78 of the elastic accelerator 7 is controlled through the control system, so that the strong spring 74 applies initial kinetic energy to the movable seat 6 to strengthen the kinetic energy of the pressure test and simulate different pressure impact situations to detect the pressure resistance performance of the doll model toy under different pressures.

[0067] S5. During the pressure test process, the magnitude of the pressure between the A flexible fixture 3 and the B flexible fixture 64 and the doll model toy can be monitored in real time through a pressure sensor (not shown in the figure) installed on the device, and the data is transmitted to the control system. The operator can adjust and optimize the test process according to the test requirements and the pressure data.

[0068] When performing the impact experiment: (refer to Figure 1 and Figure 2 );

[0069] S1. First, the ejector pin of the A flexible fixture 3 is retracted to the top of the base 1 through the control system to ensure that the ejector pin will not interfere with the impact experiment.

[0070] S2. Move the support frame 8 to the specified position and fix it through the bolt 83.

[0071] S3. Place the doll model toy at a suitable position on the base 1, and then start the hydraulic cylinder 5 through the control system. The hydraulic cylinder 5 drives the movable seat 6 to move downward. When the elastic adsorbent 65 on the movable seat 6 contacts the doll model toy, the electromagnetic chuck 652 is powered off and the pneumatic suction nozzle 657 works, so that the doll model toy is adsorbed by the elastic adsorbent 65. At the same time, the locking structure 655 locks the position of the movable column 654 to ensure that the doll model toy is firmly adsorbed on the elastic adsorbent 65.

[0072] S4. The hydraulic cylinder 5 drives the movable seat 6 to move upward to a certain height and then releases it, causing the doll model toy to fall from different heights for impact experiments. During the impact experiment, the falling height of the doll model toy can be changed by adjusting the stroke of the hydraulic cylinder 5 to simulate different falling scenarios and detect the impact resistance performance of the doll model toy under impact conditions.

[0073] S5. If the height of the impact experiment is insufficient and cannot meet the test requirements, the A electromagnet 13 can be powered off through the control system. At the same time, the elastic attachment 65 releases the doll model toy. At this time, the elastic accelerator 7 applies initial kinetic energy to the movable seat 6, causing the movable seat 6 and the doll model toy to accelerate downward. When the movable seat 6 falls to the position of the support frame 8, the C electromagnet 81 and the D electromagnet 82 generate repulsive forces, and the movable seat 6 is blocked by the support frame 8. However, the doll model toy continues to fall on the base 1 due to inertia, thereby strengthening the kinetic energy of the impact experiment and further detecting the performance of the doll model toy under higher-energy impacts.

[0074] S6. During the impact experiment, the impact process and state of the doll model toy can be recorded by a high-speed camera (not shown in the figure) installed around the base 1 for subsequent analysis and evaluation of the test results.

[0075] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
