Description

Technical Field

[0001] This utility model belongs to the technical field of battery cell manufacturing equipment, and in particular relates to a side tooth alignment mechanism. Background Technology

[0002] During the production of solar cells, there is a process called the cell guiding process, which requires stacking two solar cells back to back in a basket and then placing them into a transfer boat. In the prior art, Chinese Patent Publication CN222146260U discloses a multi-station robotic wafer guiding device for feeding and receiving. The multi-axis robotic handling mechanism transports the battery cells from the basket to the transfer boat. To ensure subsequent stacking and assembly operations, a first alignment mechanism is set up to align the battery cells in the basket before the multi-axis robotic handling mechanism transports the battery cells. Since the first alignment mechanism corresponds to two baskets, and the battery cells in the other basket are placed in the opposite direction, and the two baskets are fed at the same time, the first alignment mechanism is equipped with two alignment fixtures: a main alignment fixture and a secondary alignment fixture. The main alignment fixture and the secondary alignment fixture are connected together by a linkage to achieve linkage, resulting in a complex design structure. Now, the wafer guiding device has been optimized so that the alignment mechanism only corresponds to one basket. If the alignment mechanism continues to use two alignment fixtures, it introduces unnecessary complexity, cost, and potential failure points.

[0003] Therefore, it is necessary to provide a side tooth alignment mechanism to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a side tooth alignment mechanism that reduces the overall height, makes the layout more compact, improves stability, and can quickly adapt to different specifications and quantities of battery cells, thus improving versatility.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a side tooth alignment mechanism, comprising a mounting frame, a first motor and a second motor mounted on the mounting frame, a first transmission belt driven by the first motor for horizontal transmission, a second transmission belt driven by the second motor for horizontal transmission, and a first alignment fixture and a second alignment fixture horizontally slidably mounted on the mounting frame. The first transmission belt and the second transmission belt are arranged side by side, one end of the first alignment fixture is fixed to the first transmission belt, and one end of the second alignment fixture is fixed to the second transmission belt. The first alignment fixture and the second alignment fixture are parallel to each other and cooperate with each other to achieve left and right approach or separation.

[0006] Furthermore, both the first and second straightening fixtures include a first support plate, a straightening plate disposed on the first support plate, a plurality of straightening side teeth arranged at equal intervals along the front-back direction on one side of the straightening plate, and a bottom support plate disposed below the first support plate.

[0007] Furthermore, the alignment plate is detachably mounted on the first support plate via a first fastener.

[0008] Furthermore, the straightening side teeth on the first straightening fixture and the second straightening fixture are arranged opposite each other, and there is a gap between two adjacent straightening side teeth to form a straightening tooth groove for limiting the position of the battery cell. The two adjacent straightening side teeth limit the front and rear position of the battery cell, and the inner surface of the straightening plate constitutes a limiting surface for the left and right sides of the battery cell.

[0009] Furthermore, both the first and second straightening fixtures include a movable frame slidably mounted on the mounting frame. One end of the movable frame of the first straightening fixture is fixed to the first transmission belt by a first belt clip, and one end of the movable frame of the second straightening fixture is fixed to the second transmission belt by a second belt clip. One end of the first support plate is adjustable in vertical position at the end of the movable frame, and the other end extends out of the mounting frame.

[0010] Furthermore, one end of the first support plate is provided with a plurality of oblong holes, and the movable frame is provided with a plurality of positioning holes. The second fastener can be selectively inserted into the positioning holes and the oblong holes to realize the installation of the movable frame and the first support plate.

[0011] Furthermore, limiting members are provided on the inner sides of the two movable frames facing each other, and the two limiting members are arranged opposite each other to each other.

[0012] Furthermore, the mounting frame includes a vertical plate and a horizontal plate, and the horizontal plate is provided with several slide rails along the left and right direction. The movable frame is slidably mounted on the slide rails by a slider.

[0013] Furthermore, sensors are provided at both ends of the horizontal plate, and detection plates for the sensors to sense are correspondingly provided on the movable frame.

[0014] Furthermore, the vertical plate is provided with a first transmission shaft and a second transmission shaft. The first transmission shaft and the second transmission shaft are set at the same height on the left and right, and the length of the first transmission shaft is greater than the length of the second transmission shaft. The first transmission belt is wound around the output shaft end of the first motor and the first transmission shaft to realize rotational transmission. The second transmission belt is wound around the output shaft end of the second motor and the second transmission shaft to realize rotational transmission. The output shaft end of the first motor is located behind the output shaft end of the second motor.

[0015] Compared with the prior art, the beneficial effects of the side tooth alignment mechanism of this utility model are as follows: (1) The first and second transmission belts are arranged side by side and at the same height, rather than stacked one on top of the other, which reduces the overall height and significantly reduces the space occupied by the straightening mechanism in the vertical direction, making the equipment structure more compact; it can optimize the spatial layout and leave space above the equipment, which is convenient for integrating other automation modules to achieve more complex assembly line operations; it improves stability, as the two transmission belts are located on the same horizontal plane, and the force couple balance of driving the two straightening fixtures is better, which may reduce the torque or vibration caused by asynchrony; (2) The alignment plates of the first alignment fixture and the second alignment fixture are detachably mounted on the first support plate by the first fastener. Different lengths of alignment plates can be replaced as needed, which has strong versatility and flexibility. By replacing the alignment plates (and the side teeth on them) of different lengths, one set of mechanisms can quickly adapt to different specifications and quantities of battery cells without replacing the entire alignment fixture or alignment mechanism, reducing costs and changeover time, and reducing equipment modification costs and production line changeover downtime. (3) The first support plate of the first and second alignment fixtures can be adjusted up and down through the design of waist-shaped holes and multiple positioning holes, so that the alignment plate (and the side teeth on it) can be adjusted up and down to adapt to different battery cell sizes, further expanding the application range of the equipment and improving its versatility. (4) Both the first and second alignment fixtures adopt double slide rail support and widened and thickened moving frame, which can resist deformation, ensure long-term accuracy, effectively overcome the bending moment and sagging risk caused by the cantilever extension of the alignment fixture, ensure that the flatness and straightness of the alignment plate remain unchanged in long-term use, improve the running stability, and the robust structure reduces the vibration generated during high-speed start-stop or reversal, making the movement more stable and helping to improve the repeatability and service life of the alignment action. (5) The first and second straightening fixtures are driven by two independent motors and are used in conjunction with sensors and detection plates for closed-loop position control. Each straightening fixture can move independently, and can not only perform synchronous approach and separation actions, but also move to different work positions in the basket to selectively straighten non-standard or specific battery cells, which is highly flexible. (6) By placing the first motor behind the second motor and cleverly arranging the layout of the first drive shaft and the first drive shaft (long shaft and short shaft), the parallel arrangement of the two belts is realized in a limited space, and a compact transmission system layout is achieved. Two complete transmission systems are efficiently arranged in a limited mounting bracket area, making the overall structure of the correction mechanism more compact. Attached Figure Description

Detailed Implementation

[0017] Please refer to Figure 1-2 This embodiment is a side tooth alignment mechanism 100, which includes a mounting frame 1, a first motor 2 and a second motor 3 mounted on the mounting frame 1, a first transmission belt 4 driven by the first motor 2 for horizontal transmission, a second transmission belt 5 driven by the second motor 3 for horizontal transmission, and a first alignment fixture 6 and a second alignment fixture 7 horizontally slidably mounted on the mounting frame 1. The first transmission belt 4 and the second transmission belt 5 are arranged side by side and at the same height. One end of the first alignment fixture 6 is fixed to the first transmission belt 4, and one end of the second alignment fixture 7 is fixed to the second transmission belt 5. The first alignment fixture 6 and the second alignment fixture 7 are parallel to each other and cooperate with each other to achieve left and right approach or separation.

[0018] The first straightening fixture 6 and the second straightening fixture 7 have the same or similar structure, and both include a first support plate 71, a straightening plate 72 disposed on the first support plate 71, a plurality of straightening side teeth 73 arranged at equal intervals along the front-back direction on one side of the straightening plate 72, and a bottom support plate 74 disposed below the first support plate 71.

[0019] The support plate 64 is positioned below the first support plate 71 via several connecting rods 75 to ensure the connection strength of the support plate 64.

[0020] One side of the alignment plate 72 is covered with alignment teeth. The alignment plate 72 is elongated to allow for alignment of more solar cells. The alignment plate 72 is detachably mounted on the first support plate 71 via a first fastener. If different numbers of solar cells need to be aligned, alignment plates 72 of different lengths can be replaced. This is simple, convenient, adaptable to different application scenarios, and offers good flexibility and versatility.

[0021] The first and second straightening fixtures 6 and 7 have straightening side teeth 73 arranged opposite each other to facilitate the straightening of the left and right sides of the battery cells. A gap is provided between two adjacent straightening side teeth 73 to form straightening grooves that limit the position of the battery cells. The straightening grooves correspond to the number and position of the battery cells in the basket. During straightening, each straightening side tooth 73 is inserted between two battery cells, and each battery cell is simultaneously engaged in a straightening groove. Two adjacent straightening side teeth 73 limit the front and rear positions of the battery cells. The inner surface of the straightening plate 72 forms a limiting surface 76 for the left and right sides of the battery cells. To ensure straightening accuracy, the limiting surface 76 is a precision-machined plane.

[0022] Both the first alignment fixture 6 and the second alignment fixture 7 include a movable frame 77 slidably mounted on the mounting frame 1. One end of the movable frame 77 of the first alignment fixture 6 is fixed to the first transmission belt 4 via a first belt clip 78, and one end of the movable frame 77 of the second alignment fixture 7 is fixed to the second transmission belt 5 via a second belt clip 79. One end of the first support plate 71 is adjustable in height at the end of the movable frame 77, and the other end protrudes beyond the mounting frame 1. The adjustable height of the first support plate 71 allows for vertical adjustment of the height of the alignment side teeth 73, facilitating the adaptation to different sizes of battery cells and improving versatility. Limiting members 772 are provided on the inner sides of the two movable frames 77, positioned opposite each other to prevent collision between the two movable frames 77, thereby preventing collision between the first alignment fixture 6 and the second alignment fixture 7.

[0023] Specifically, one end of the first support plate 71 is provided with several oblong holes 711, and the movable frame 77 is provided with several positioning holes 771, with the number of positioning holes 771 exceeding the number of oblong holes 711. The second fastener can be selectively inserted into the positioning holes 771 and oblong holes 711 to install the movable frame 77 and the first support plate 71. If it is necessary to adjust the height of the straightening side tooth 73, loosen the second fastener, move the first support plate 71 up and down, and insert the second fastener into the corresponding positioning hole 771 and oblong hole 711 and tighten it to adjust the height of the straightening side tooth 73.

[0024] The first and second fasteners are selected from one of the bolts, screws, and pins, or other fasteners. Their specific structures are not limited here and can be set according to the actual situation.

[0025] The mounting frame 1 includes a vertical plate 11 and a horizontal plate 12. Several slide rails 121 are arranged on the horizontal plate 12 along the left-right direction. The movable frame 77 is slidably mounted on the slide rails 121 via a slider 122. In this embodiment, since the first support plate 71 is cantilevered, to avoid the first support plate 71 becoming weak and bending, which could affect the alignment accuracy of the alignment plate 72 and the alignment side teeth 73, two slide rails 121 are provided on the horizontal plate 12 to achieve double support. Furthermore, the movable frame 77 is widened and thickened to ensure the strength of the first support plate 71, thereby ensuring the alignment accuracy of the alignment plate 72 and the alignment side teeth 73. In other embodiments, the number of slide rails 121 can be increased according to the actual space to further enhance the support for the first support plate 71 and ensure its strength. Therefore, the number of slide rails 121 is not limited here and can be set according to the actual situation.

[0026] Sensors 13 are installed at both ends of the horizontal plate 12. Correspondingly, a detection plate 14 is installed on the movable frame 77 for the sensors 13 to sense. The sensors 13 sense the position of the detection plate 14 and transmit the position signal to the first motor 2 and the second motor 3 to determine the rotation direction of the first motor 2 and the second motor 3. The first motor 2 and the second motor 3 can drive the first straightening fixture 6 and the second straightening fixture 7 to move left and right to perform straightening operations, and can also move the first straightening fixture 6 and the second straightening fixture 7 to different positions in the flower basket, thereby performing straightening operations on the battery cells in different positions in the flower basket, improving flexibility and versatility.

[0027] A first drive shaft 15 and a second drive shaft 16 are provided on the vertical plate 11. Both the first drive shaft 15 and the first drive shaft 16 are provided with drive wheels. The first drive shaft 15 and the second drive shaft are set at the same height on the left and right, and the length of the first drive shaft 15 is greater than the length of the second drive shaft 16. The first drive belt 4 is wound around the output shaft end of the first motor 2 and the first drive shaft 15 to achieve rotational transmission. The second drive belt 5 is wound around the output shaft end of the second motor 3 and the second drive shaft 16 to achieve rotational transmission. The output shaft end of the first motor 2 is located behind the output shaft end of the second motor 3. This design allows the first drive belt 4 and the second drive belt 5 to be arranged side by side. Compared with the prior art Chinese Patent Announcement CN222146260U, which discloses a multi-station material receiving robot guide device, the first straightening mechanism of this solution has two drive belts arranged side by side, which can reduce the height of the vertical plate 11 and leave height space for the operation of other modules.

[0028] When applying the side tooth alignment mechanism 100 provided by this solution, in the initial state, the first alignment fixture 6 and the second alignment fixture 7 are in a semi-separated state. When it is necessary to align the battery cells in the basket, the first motor 2 drives the first alignment fixture and the second motor 3 drives the second alignment fixture 7 to move closer to each other. The alignment plate 72 and the alignment side teeth 73 are used to align the left and right sides and the front and back positions of the battery.

[0029] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
