Description

Technical Field

[0001] The utility model relates to the field of detection instruments, and in particular to a high-precision balance housing for weighing solar cells. Background Art

[0002] A balance that uses electromagnetic force to balance the gravity of an object to be weighed is called an electronic balance. It uses an electronic device to complete the adjustment of electromagnetic force compensation, so that the object achieves force balance in the gravity field, or through the adjustment of electromagnetic torque, so that the object achieves torque balance in the gravity field. The structures of common electronic balances are all electromechanical combined types, which are composed of components such as load acceptance and transmission devices, measurement and compensation devices, etc., and can be divided into two categories: top-loading type and bottom-loading type. According to the basic electromagnetic theory, a current-carrying wire will generate electromagnetic force or Ampere force in a magnetic field. The directions of the force, the magnetic field, and the current are perpendicular to each other. When the magnetic field strength remains unchanged, the magnitude of the generated electromagnetic force is proportional to the current intensity flowing through the coil. Its characteristics are accurate and reliable weighing, fast and clear display, and having an automatic detection system, a simple automatic calibration device, and an overload protection device, etc.

[0003] At present, when operators weigh various solar cells, they often need to use a high-precision balance, which is convenient for the accuracy of process control of production line operators. In the actual use of existing high-precision balances, although adding a baffle that can hold solar cells at the bottom can achieve a basic weighing effect, because the bottom baffle will affect the stability of the accuracy, and it is not convenient to take and place solar cells when using a windproof cover with a baffle inside.

[0004] For example, the "High-precision Balance for Weighing Raw Materials" disclosed in the Chinese patent literature, with the publication number CN218211606U, includes a balance body, a placement plate is fixedly installed on the top of the balance body, a positioning block located outside the placement plate is fixedly installed on the top of the balance body, and a windproof cover is movably sleeved on the top of the balance body. The disadvantage of this patent is that when used to weigh solar cells, the presence of the windproof cover makes it inconvenient to take and place solar cells, and it is easy to cause the situation that the solar cells collide with the side wall of the windproof cover and are damaged. Summary of the Utility Model

[0005] The utility model is to overcome the problem that when weighing solar cells with a high-precision balance in the prior art, the presence of the windproof cover makes it inconvenient to take and place solar cells, and it is easy to cause the solar cells to collide with the side wall of the windproof cover and be damaged, and provides a high-precision balance housing for weighing solar cells, which can achieve a protective effect while avoiding affecting the placement and taking of solar cells.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The present utility model relates to a high-precision balance cover for weighing battery wafers, which includes a base and an upper cover installed on the upper side of the balance body. The base is provided with a clamping portion, and the upper cover is adaptively installed in the clamping portion.

[0008] In this application, the base and the upper cover that are closed up and down replace the windproof cover in the prior art. When the upper cover is opened, the process of placing the battery wafer on the base is not blocked, so that situations such as collision damage will not occur. Moreover, by closing the upper cover and the base, it can play a protective effect on the weighing position and avoid affecting the weighing accuracy. The clamping portion enables the upper cover to be limited on the base and is not easy to fall off.

[0009] Preferably, a pushing track is provided on the upper side of the base. The pushing track can facilitate the safe placement of the battery wafer to the middle position of the base.

[0010] Preferably, the upper side of the pushing track is an arc surface. The arc surface can reduce the friction between the battery wafer and the pushing track, making it easier to place the battery wafer.

[0011] Preferably, the upper cover is rotatably connected to the base. By flipping open the upper cover, it is more convenient to operate.

[0012] Preferably, a flipping handle is provided on the front side of the upper cover. The flipping handle facilitates the operator to pull the upper cover.

[0013] Preferably, the upper cover and the base are connected by a hinge, and one of the hinge plates is connected to the upper cover, and the other hinge plate is connected to the base.

[0014] Preferably, a lifting handle is provided on the upper side of the upper cover. The lifting handle facilitates the operator to lift the upper cover that can be separated from the base.

[0015] Preferably, a side flap is also installed on the upper cover. The side flap can play a protective effect by blocking the gap between the side walls of the upper cover and the base.

[0016] Preferably, the side flap is installed on the upper cover by a hinge.

[0017] Therefore, the present utility model has the following beneficial effects: (1) It can protect the weighing position and avoid affecting the weighing accuracy; (2) It can avoid the battery wafer being damaged by collision when putting in and taking out the battery wafer; (3) The battery wafer is easy to place.

[0025] The following further describes the present utility model in conjunction with the drawings and specific implementation manners.

[0026] Embodiment 1, as Figure 1-2 shown, a high-precision balance housing for weighing battery cells includes a base 1 and an upper cover 2 installed on the upper side of the balance body. The base 1 is provided with a clamping part 3, and the lower side of the upper cover 2 is provided with a boss adapted to the clamping part 3. The upper cover 2 is adaptively installed in the clamping part 3 through the boss. The lower side of the upper cover 2 is also provided with a rubber pad. The housing is installed above the balance body, and the base 1 and the upper cover 2 are two separate parts. When weighing is not carried out, the upper cover 2 covers the base 1 to prevent the base 1 from being collided or its accuracy being affected due to sundries falling on the base 1. When weighing, the upper cover 2 is removed from the base 1, then the battery cell is placed on the base 1, and then the upper cover 2 is covered on the battery cell for weighing, so as to ensure the accuracy of weighing. At this time, the upper cover 2 plays a role of pressing and fixing the battery cell. The elastic pad can play a buffering role for the base 1 and the battery cell, prevent damage to the base 1 and the battery cell, and also play a role of increasing friction.

[0027] In this embodiment, the number of clamping parts 3 is four, which are distributed at the four corners of the base 1. The shape of the clamping part 3 is L-shaped, and its right-angled part is used to limit the upper cover 2. The upper cover 2 also has four bosses, which correspond to the clamping parts 3 one by one. The bosses also include two mutually perpendicular clamping edges, so as to form a clamping connection with the base 1.

[0028] A handle 5 is provided on the upper side of the upper cover 2. An opening facilitating the insertion of a hand is formed between the handle 5 and the upper cover 2, so that an operator can easily lift the handle 5 upward.

[0029] A pushing track 4 is provided on the upper side of the base 1. The upper side of the pushing track 4 is an arc surface. There are two pushing tracks 4, and the two pushing tracks 4 are parallel to each other. The direction of the pushing track 4 is the front-back direction. The reference for the front-back direction is that the side where the control panel of the balance is located is the front side. Through the setting of the pushing track 4, it can be ensured that when preventing the battery wafers, the possibility of damaging the battery wafers is minimized to the greatest extent, and the rejection rate is reduced. The upper end of the pushing track 4 should be higher than the upper end position of the clamping portion 3, so as to avoid the possibility of the battery wafers colliding with the clamping portion 3 during the pushing process.

[0030] When weighing the battery wafers, first tare and zero the balance, and then lift and remove the upper cover 2 upward through the handle 5. Then, place the rear part of the battery wafer on the pushing track 4 and push the battery wafer from front to back. After the battery wafer moves to the central position of the base 1, place the upper cover 2 on the battery wafer to tightly fix the battery wafer. Weighing is carried out. After the weighing is completed, remove the battery wafer, and then cover the upper cover 2 back on the base 1 to protect the base 1. During the process of covering the upper cover 2 back, its convex platform is fitted into the base 1 to form a limit for the upper cover 2.

[0031] Embodiment 2, as Figure 3-4 shown, a high-precision balance outer cover for weighing battery wafers includes a base 1 and an upper cover 2 installed on the upper side of the balance body. A clamping portion 3 is provided on the base 1, and a convex platform adapted to the clamping portion 3 is provided on the lower side of the upper cover 2. The upper cover 2 is adaptively installed in the clamping portion 3 through the convex platform. An elastic pad is provided on the lower side of the upper cover 2. The upper cover 2 and the base 1 are rotatably connected. The specific form of the rotatable connection is that the upper cover 2 and the base 1 are connected by a hinge 7. One of the leaf plates of the hinge 7 is connected to the upper cover 2, and the other leaf plate is connected to the base 1. When not weighing, the upper cover 2 covers the base 1 to prevent the base 1 from being collided or its accuracy being affected due to sundries falling on the base 1. When weighing, turn the upper cover 2 up from the base 1, then place the battery wafer on the base 1, and then cover the upper cover 2 on the battery wafer for weighing, so as to ensure the accuracy of weighing. At this time, the upper cover 2 plays a role in tightly fixing the battery wafer. The elastic pad can play a buffering role for the base 1 and the battery wafer, prevent damage to the base 1 and the battery wafer, and also play a role in increasing friction. A limit bolt 8 is installed at the rear side of the upper cover 2. When the upper cover 2 is turned up, the limit bolt 8 will rotate together with the upper cover 2 and be limited by the balance body. In this way, the problem of the upper cover 2 turning over too much and causing imbalance can be avoided.

[0032] In this embodiment, there are two clamping portions 3, which are distributed at two of the front corner portions of the base 1.

[0034] A pushing track 4 is provided on the upper side surface of the base 1. The upper side surface of the pushing track 4 is an arc surface. There are two pushing tracks 4, and the two pushing tracks 4 are parallel to each other. The direction of the pushing track 4 is the front-back direction. The reference of the front-back direction is that the side where the control panel of the balance is located is the front side. Through the setting of the pushing track 4, it can be ensured that when preventing the battery sheet, the possibility of damaging the battery sheet is minimized to the greatest extent, and the rejection rate is reduced. The upper end of the pushing track 4 should be higher than the upper end position of the clamping portion 3, so as to avoid the possibility of the battery sheet colliding with the clamping portion 3 during the pushing process.

[0035] When it is necessary to weigh the battery sheet, first turn up the upper cover 2 through the flip handle 6, so that the balance is opened. After taring and zeroing the balance, then place the rear part of the battery sheet on the pushing track 4 and push the battery sheet from front to back. After the battery sheet moves to the central position of the base 1, then close the upper cover 2 to tightly fix the battery sheet. Weigh it. After the weighing is completed, remove the battery sheet and cover the upper cover 2 back on the base 1 to protect the base 1.
