Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a weighing module device. Background Technology

[0002] In pharmaceutical manufacturing and drug testing, the accuracy of drug weighing is crucial, as it is a key factor in ensuring drug quality and dosage accuracy.

[0003] Existing pharmaceutical weighing equipment typically consists of a container and a sensor. First, the medicine is placed on the container, which transmits the weight of the medicine to the sensor. The sensor converts the weight signal into an electrical signal and transmits it to the controller. After processing the electrical signal, the controller displays the weight value on the display screen. However, existing weighing equipment only uses one support point to support the weight of the object being measured. During measurement, when the center of gravity of the object being measured deviates from the center of the support point, the container will deform, affecting the sensor's perception and causing errors in the measurement data.

[0004] In view of this, we provide a weighing module device to solve the above problems. Utility Model Content

[0005] The purpose of this application is to solve the technical problem that when the center of gravity of the object being measured deviates from the center of the support point during measurement, the container will deform, affecting the sensor's perception and causing errors in the measurement data. In order to solve the above technical problem, a weighing module device is provided that the container will not deform when the center of gravity of the object being measured deviates from the center of the support point during measurement, thus not affecting the sensor's perception and ensuring accurate measurement data.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solution: a weighing module device, comprising: a container, a fixing member, and a base, the base being provided with mounting holes; a sensor, the sensor being disposed at the top of the base, with connection holes one and two respectively provided on both sides of the sensor; wherein, a pad, the pad being disposed at the upper end of the sensor, the pad being provided with connection holes three, the connection holes three being axially aligned with the connection holes two; a mounting plate being disposed at the bottom of the container, the mounting plate being used to improve the load-bearing strength of the container, the container and the mounting plate being provided with connection holes four and five respectively, the connection holes four and five being aligned with the connection holes three along the same axis, the fixing member sequentially passing through connection holes four, five, three and two to form a rigid connection between the container, the mounting plate, the pad, and the sensor; the container is used to place the object to be measured, the mounting plate being disposed at the bottom of the container to distribute the weight of the object to be measured, avoiding weight transmission deviation caused by container deformation under force, the pad raising the container and the mounting plate as a whole, isolating the interference of the container's weight deformation on the sensor, thereby ensuring accurate measurement data.

In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0027] Example 1:

[0028] like Figure 1 , 2 As shown, this embodiment provides a weighing module device, including: a container 5, a fixing member 6 and a base 1, the base 1 being provided with mounting holes 11; a sensor 2, the sensor 2 being disposed at the top of the base 1, the sensor 2 being provided with connection hole one and connection hole two 21 on both sides respectively; wherein, a pad 3, the pad 3 being disposed at the upper end of the sensor 2, the pad 3 being provided with connection hole three 31, the connection hole three 31 being axially aligned with connection hole two 21; A mounting plate 4 is provided at the bottom of the container 5. The mounting plate 4 is used to improve the load-bearing strength of the container 5. The container 5 and the mounting plate 4 are respectively provided with connection hole 41 and connection hole 52. Connection hole 41 and connection hole 52 are aligned with connection hole 31 along the same axis. The fastener 6 passes through connection hole 41, connection hole 52, connection hole 31 and connection hole 21 in sequence to form a rigid connection between the container 5, the mounting plate 4, the pad 3 and the sensor 2. The container 5 is used to place the object to be measured. The mounting plate 4 is set at the bottom of the container 5 to distribute the weight of the object to be measured and avoid the weight transmission deviation caused by the deformation of the container 5 under force. The pad 3 raises the container 5 and the mounting plate 4 as a whole and isolates the interference of the container 5 on the sensor 2 due to the weight deformation, so as to ensure the accuracy of the measurement data.

[0029] During weighing measurement, the object to be measured is placed inside container 5. The mounting plate 4 at the bottom of container 5 distributes the weight of the object to prevent deformation of container 5. The pad block 3 raises container 5 and mounting plate 4 as a whole and rigidly connects them to sensor 2, isolating the interference of deformation of container 5 due to weight on sensor 2. Multiple sensors 2 are symmetrically distributed with container 5 on base 1 to ensure uniform force on base 1, ensuring that container 5 and sensor 2 do not shift or shake during measurement. This solves the technical problem that when the center of gravity of the object to be measured deviates from the center of the support point, container 5 will deform, affecting the sensing of sensor 2 and causing measurement data errors. It achieves the technical effect that when the center of gravity of the object to be measured deviates from the center of the support point, container 5 will not deform, will not affect the sensing of sensor 2, and ensures accurate measurement data.

[0030] Example 2:

[0031] like Figure 1 , 2 As shown, several sensors 2 are provided, and each sensor 2 has a pad 3 on its top. The bottom diameter of the pad 3 is the same as the top diameter of the connecting surface of the sensor 2.

[0032] Several sensors 2 are symmetrically arranged in an array on the base 1, and each sensor 2 is equipped with an independent pad 3 on its top. The pad 3 is tightly attached to the top surface of the sensor 2 and is rigidly connected to the container 5 by a fastener 6, forming an independent load-bearing unit. During weighing, the object to be measured is placed in each container 5, and its weight is evenly transferred to each pad 3 through the mounting plate 4 at the bottom of each container 5, and then vertically transmitted to the corresponding sensor 2 by the pad 3. The multiple sensors 2 and pads 3 are symmetrically arranged on the base 1. When the center of gravity of the object to be measured deviates, the eccentric torque is offset by the synchronous force of each load-bearing unit, avoiding local overload of the base 1 and causing tilting. The pads 3 physically isolate the container 5 from the sensor 2, preventing the deformation of the container 5 due to load from interfering with the sensor 2, ensuring that the sensor 2 only senses the effective weight in the vertical direction, without affecting the sensor 2's sensing, thus ensuring accurate measurement data.

[0033] like Figure 1 , 3 As shown, the shape of the mounting plate 4 is the same as the bottom shape of the container 5, and several fixing holes 41 are provided around the mounting plate 4.

[0034] The mounting plate 4 is rigidly connected to the container 5 via peripheral fixing holes 41, enhancing structural stability. The shape of the mounting plate 4 is identical to that of the bottom of the container 5, maximizing the contact area between them. When the object to be measured is placed inside the container 5, the weight can be evenly distributed to the bottom through the mounting plate 4, preventing the container 5 from denting or deforming due to localized stress, thus avoiding measurement errors. The fixing holes 41 on the peripheral side of the mounting plate 4 can be fastened to the corresponding holes on the bottom of the container 5 using screws, bolts, or other fasteners 6, forming an integrated rigid assembly. This enhances the deformation resistance of the bottom of the container 5, ensuring that the weight is stably transmitted vertically to the pad 3 and sensor 2 below, preventing force transmission deviation due to connection gaps. During the weighing process, the weight of the object being measured is transferred from container 5 to mounting plate 4, and then evenly applied to pad 3 and sensor 2 via the bottom surface of mounting plate 4. The elastic body inside sensor 2 undergoes precise deformation due to the force, driving the strain gauge to output a reliable electrical signal. An annular elastic groove is formed around the fixing hole 41, filled with a rubber ring. When container 5 is subjected to impact or vibration, the rubber ring in the annular elastic groove absorbs and buffers the impact force through elastic deformation, preventing the fixing hole 41 from undergoing plastic deformation due to instantaneous overload, and reducing the interference of vibration on sensor measurement. This effectively solves the technical problem that when the center of gravity of the object being measured deviates from the center of the support point during measurement, container 5 deforms, affecting the sensing of sensor 2 and causing measurement data errors. It achieves the technical effect that when the center of gravity of the object being measured deviates from the center of the support point during measurement, container 5 will not deform, thus not affecting the sensing of sensor 2, ensuring accurate measurement data.

[0035] like Figure 1 , 4 As shown, the number of containers 5 is the same as the number of sensors 2, and the thickness of the center of sensor 2 is less than the thickness of the sides of sensor 2. The periphery of container 5 is rounded, and the periphery of the opening of container 5 is provided with an outwardly extending convex ring.

[0036] When container 5 transfers weight, the central part of sensor 2 preferentially undergoes elastic deformation, causing a change in resistance in the internal strain gauge, thus accurately converting the weight signal into an electrical signal. The thick-walled structure on both sides restricts unnecessary deformation, avoiding measurement errors caused by lateral forces or bending moments, ensuring that sensor 2 only responds to the effective weight in the vertical direction, thereby improving measurement accuracy.

[0037] Each container 5 corresponds to a sensor 2, forming an independent and symmetrical load-bearing unit. During weighing, the object to be measured is placed inside the container 5, and the weight is directly and vertically transmitted to the sensor 2 below. This avoids uneven force distribution caused by multiple containers 5 sharing the sensor 2. When the center of gravity of the object to be measured shifts, the symmetrically distributed containers 5 and sensors 2 are simultaneously subjected to force. The mutual cancellation of forces balances the off-center load torque, ensuring that the base 1 is subjected to uniform force as a whole. This prevents structural tilting and measurement deviation caused by eccentric force. It achieves the technical effect that when the center of gravity of the object to be measured deviates from the center of the support point during measurement, the container 5 will not deform and will not affect the sensing of the sensor 2, ensuring accurate measurement data.

[0038] like Figure 1 As shown, the first connecting hole and the mounting hole 11 are aligned on the same axis. The sensor 2 is fixedly connected to the base 1 through the fastener 6, which passes through the first connecting hole and the mounting hole 11. The base 1 is rectangular in shape and has several positioning holes arranged in a rectangular array on the base 1.

[0039] The first connecting hole is aligned with the axis of the mounting hole 11, ensuring a precise and error-free connection between the sensor 2 and the base 1. The fastener 6 passes through both holes, forming a robust rigid connection. This ensures that the sensor 2 only undergoes elastic deformation within its design range under stress, preventing lateral forces caused by installation misalignment from interfering with the measurement results. The rectangular base 1 and the rectangular array of positioning holes provide a stable installation reference for the entire weighing module. The positioning holes can cooperate with the positioning pins of external equipment to ensure the positional accuracy of the base 1 during installation, preventing the sensor 2 from being affected by shaking or shifting of the base 1. The array layout of multiple positioning holes can evenly distribute the external forces on the device, maintaining the stability of the base 1 even when the weight of the measured object is uneven. During installation, the base 1 is first precisely positioned and fixed to the external equipment through the positioning holes. Then, the first connecting hole of the sensor 2 is aligned with the mounting hole 11 of the base 1, and the fastener 6 is used for the through connection to complete the sensor 2 installation. During weighing, the weight of the measured object is transmitted to the sensor 2. Due to the precise connection between the sensor 2 and the base 1 and the stable support of the base 1, the sensor 2 can accurately convert the weight into an electrical signal, ensuring accurate measurement data.

[0040] like Figure 1 As shown, the sensor 2 has a hole in the middle, and the fastener 6 passes through several fixing holes 41 to further fix the mounting plate 4 to the container 5.

[0041] The hole in the middle of sensor 2 can effectively guide stress distribution. By adjusting the shape and position of the hole, the concentrated stress can be evenly distributed to the edge area of ​​sensor 2, avoiding local overload that could damage the elastomer and cause measurement deviation. At the same time, the fastener 6 passes through the fixing hole 41 of the mounting plate 4 and the container 5, firmly connecting the two into one, which enhances the overall rigidity. This connection method effectively prevents the relative displacement or shaking of the mounting plate 4 and the container 5 during the weighing process. Even if the center of gravity of the measured object shifts, the weight can still be stably transmitted to sensor 2, avoiding measurement errors caused by structural loosening. This achieves the technical effect that when the center of gravity of the measured object deviates from the center of the support point during measurement, the container 5 will not deform, and the sensor 2's sensing will not be affected, ensuring accurate measurement data.
