[0030] Combine the following Figures 1 to 5 The utility model describes a current collecting plate positioning support cup assembly and a current collecting plate feeding device.

[0031] The cup 1 needs to be moved several times during the loading process of the collecting plate. To prevent the position and angle of the collecting plate in the cup 1 from changing during the conveying process, the utility model proposes a collecting plate positioning cup assembly.

[0032] The collecting plate positioning cup assembly provided in this embodiment includes: a cup 1 and a positioning member 2, the cup 1 is used to accommodate the collecting plate, the positioning member 2 includes a main body 22 and a right-angle portion 21, the cup 1 is arranged on the main body 22, and a limiting groove is provided on the step conveyor belt 5, the main body matches the limiting groove, and the right-angle portion 21 is arranged on one side of the main body 22, which is used to limit the position of the cup to prevent the cup 1 from changing its position and angle during the conveying process, resulting in changes in the position and angle of the collecting plate, thereby ensuring that the collecting plate is at the same angle and position for loading, thereby improving the accuracy and efficiency of subsequent production.

[0033] refer to Figure 2 and Figure 3 The right-angle portion 21 is a rectangular structure, and the body 22 is a semicircular structure. The semicircular structure is arranged on one side of the width direction of the rectangular structure, and the diameter of the semicircular structure is the same as the width of the rectangular structure.

[0034] When the collecting plate positioning cup assembly is conveyed on the conveyor belt 5, a limiting groove is provided on the conveyor belt 5, and the limiting groove is arranged along the extension direction of the conveyor belt 5. The limiting groove is used to cooperate with the rectangular structure to guide the collecting plate positioning cup assembly to be conveyed along the extension direction of the conveyor belt 5; the diameter of the semicircular structure is slightly smaller than the width of the limiting groove, and the width direction of the limiting groove is consistent with the width direction of the conveyor belt 5; the rectangular structure has a first side wall and a second side wall arranged opposite to each other, the first side wall is consistent with the extension direction of the conveyor belt 5, the second side wall is consistent with the width direction of the conveyor belt 5, and the length of the second side wall is slightly smaller than the width of the limiting groove. When the collecting plate positioning cup assembly is conveyed on the conveyor belt 5, the collecting plate positioning cup assembly is prevented from rotating and moving on the conveyor belt 5. On the one hand, the angles of the collecting plates in each cup 1 on the conveyor belt 5 are made consistent, and on the other hand, the positions between adjacent cups 1 are made relatively fixed, that is, the positions of adjacent collecting plates are relatively fixed.

[0035] The current collecting plate positioning cup assembly on the step conveyor belt 5 is transferred to the turntable 4, and the turntable 4 drives the current collecting plate positioning cup assembly to transfer it to the next station. Figure 4 The outer edge of the turntable 4 is provided with a notch 41, and the right-angled side of the rectangular structure matches the notch 41, that is, the right-angled side of the rectangular structure can be clamped at the notch 41, wherein the notch 41 includes a right-angled notch and an arc-shaped notch. During the rotation of the turntable 4, the current collecting disc positioning support cup assembly at the notch 41 is driven to move to realize the transmission; during the process of the turntable 4 driving the current collecting disc positioning support cup assembly to be transmitted, the right-angled side of the rectangular structure is clamped at the notch 41 to limit the self-rotation of the current collecting disc positioning support cup assembly, that is, to prevent the angle and position of the current collecting disc in the support cup 1 from changing, thereby ensuring that the current collecting disc is at the same angle and position for loading, and improving the subsequent welding accuracy and production efficiency.

[0036] When the collecting plate positioning cup assembly in this embodiment is conveyed on the conveyor belt 5, the right-angle portion 21 of the positioning member 2 can prevent the collecting plate positioning cup assembly from rotating on the conveyor belt 5, i.e., prevent the position and angle of the collecting plate in the cup 1 from changing; when the collecting plate cup assembly on the conveyor belt 5 is conveyed to the turntable 4, the right-angle portion 21 is clamped in the notch 41 on the outer edge of the turntable 4, and the turntable 4 rotates, driving the collecting plate positioning cup assembly to be conveyed to prevent it from rotating; thereby ensuring that the position and angle of the collecting plate positioning cup assembly remain unchanged during the conveyance process, so that the collecting plate in the cup 1 is kept at the same angle and position for loading, thereby improving the subsequent welding accuracy and production efficiency.

[0037] On the basis of the above embodiments, in order to achieve precise positioning and movement, the positioning member 2 is made of magnetic material with high magnetic permeability and stable magnetic properties, and can provide a strong magnetic field and stable magnetic force, which is used to match the permanent magnet at the notch 41 on the turntable 4, and utilizes magnetic force to assist the current collecting plate positioning cup assembly to leave the step conveyor belt 5 and enter the notch 41 on the turntable 4, and make the current collecting plate positioning cup assembly enter the notch 41 on the turntable 4 at a preset angle and preset position, so that the current collecting plate in the cup 1 maintains the same angle and position for loading, thereby improving subsequent welding accuracy and production efficiency.

[0038] The collecting plate positioning support cup assembly in the utility model further comprises a limiter 3 , which is arranged between the support cup 1 and the positioning member 2 .

The permanent magnet cooperates with the magnetic material part to assist the collector plate positioning cup assembly to leave the step conveyor belt 5 and enter the notch 41 of the turntable 4. This embodiment uses the principle of the clamping connection between the right-angle portion 21 and the notch 41 and the magnetic adsorption to limit the position of the collector plate positioning cup assembly and prevent it from rotating during the conveying process, thereby ensuring that the position and angle of the collector plate in the cup 1 remain unchanged.

[0040] The top surface of the limit member 3 is connected to the bottom surface of the support cup 1, and the bottom surface of the limit member 3 is connected to the positioning member 2.

[0041] Furthermore, the diameter of the limit member 3 is smaller than the diameter of the support cup 1, so that the limit member 3 can be clamped at the loading station. For example, when the step conveyor 5 conveys the collecting plate positioning support cup assembly to the turntable 4, the collecting plate positioning support cup assembly can be clamped at the notch 41 of the turntable 4 through the limit member 3.

The integrally formed part is made of magnetic material, and when the collector plate positioning cup assembly is transferred from the step conveyor belt 5 to the turntable 4, it matches with the permanent magnet at the notch 41 on the turntable 4, so that the collector plate positioning cup assembly enters the notch 41 on the turntable 4 at a preset angle and preset position.

The first through hole 12 is connected to the second through hole 23 and serves as an air intake channel for negative pressure dust removal inside the support cup 1.

[0047] When performing negative pressure dust removal operation, the external airflow enters the interior of the cup 1 through the air inlet channel formed by the second through hole 23 and the first through hole 12, providing an airflow path for the external airflow, ensuring the air pressure balance in the cup 1 during the negative pressure dust removal process, improving the dust removal effect, and also preventing the cup 1 from being sucked during the negative pressure dust removal process.

[0048] In addition, when the collecting plate positioning support cup assembly moves to the collecting plate loading station, the collecting plate in the support cup 1 can be quickly sucked to prevent the support cup 1 from being sucked during the sucking process.
