[0035] II. Description of the Technical Problems Key to be Solved by the Embodiment

[0036] Traditional lithium battery pin leveling is a manual operation, which requires experience. Unskilled operators cannot accurately perform leveling operations, and the accuracy of correction cannot be guaranteed. It also requires a lot of manpower and is inefficient. Based on the problems of manual shaping of lithium electronic pins, this application specifically provides a technical solution to the above problems.

[0037] 3. Based on the existing problems in manually shaping the pins of lithium batteries, the technical solution, working principle and technical effects of the present application are described in detail below in conjunction with specific embodiments.

[0038] The utility model records an automatic shaping machine for lithium battery pins, which is used for automatically shaping the lithium battery pins to realize automatic and accurate correction of the lithium battery pins after deformation.

[0039] like Figure 1 , Figure 2 As shown, the automatic shaping machine for lithium battery pins includes a feeding and conveying device 1 and a shaping device 2. When working, the feeding and conveying device 1 and the shaping device 2 cooperate with each other to complete the material transmission, feeding and shaping operations.

[0040] The feeding transmission device 1 feeds the shaping device 2. The feeding transmission device 1 adopts a belt transmission mechanism, which can also be replaced by a chain transmission according to different transmission requirements. The transmission power of the feeding transmission device 1 is provided by a power motor arranged at the end of the belt transmission mechanism. The power motor adopts a servo motor, thereby ensuring the material transmission accuracy.

[0041] In order to facilitate the positioning and placement of materials, positioning blocks 101 are set in the length direction of the transmission belt. The positioning blocks 101 are evenly spaced on the belt, in groups of two, and the materials are placed between the two positioning blocks 101 for transmission. The spacing of the positioning blocks 101 set on the transmission belt is adjustable, which can be used to adjust the transmission spacing of the materials on the belt to adapt to the subsequent shaping device 2 for shaping operations.

[0042] The shaping device 2 is the main part of the whole machine in this embodiment, and its purpose is to realize the correction and leveling of the transferred materials. The shaping mechanism adopts double-station processing, and can correct two materials at the same time.

[0043] like Figure 3 As shown, the shaping device 2 mainly includes two parts: a frame 21 and a correction mechanism 22.

[0044] Among them, a supporting mechanism 3 for supporting materials is set on the frame 21, and the supporting mechanism 3 includes a pressing mechanism 31 and a lifting mechanism 32. The pressing mechanism 31 is set on an upper mounting plate set on the upper part of the frame 21, and the lifting mechanism 32 is installed on the lower mounting plate of the frame 21. The lifting mechanism 32 cooperates with the pressing mechanism 31 to lift and support the materials transmitted to the correction mechanism 22.

[0045] The pressing mechanism 31 includes a pressing drive cylinder 311 and a pressing plate 312. The pressing drive cylinder 311 is a driving cylinder. A pressing block 313 is arranged on the pressing plate 312. The pressing block 313 is installed at the lower part of the pressing plate 312. When working, the driving cylinder drives the pressing plate 312 to move, and the pressing block 313 acts on the material, thereby clamping the material. In order to avoid damage to the material caused by hard contact, a buffer spring is arranged between the pressing block 313 and the pressing plate 312 to buffer the direct impact on the material during the pressing process.

[0046] The lifting mechanism 32 includes a lifting cylinder and a lifting plate 321. The lifting plate 321 is installed on the upper part of the lifting cylinder. The lifting cylinder drives the lifting plate 321 to rise and lift the materials.

[0047] In order to ensure the stability of the lifting mechanism 32 during the material lifting process, lifting guide mechanisms 322 are provided at both ends of the lifting plate 321. The lifting guide mechanisms 322 include inclined guide blocks and guide grooves matched with the guide blocks.

[0048] During operation, when the belt transmission mechanism transmits the material to the shaping device 2, the lifting mechanism 32 lifts the material transmitted thereto, separates it from the transmission belt, and then cooperates with the pressing mechanism 31 to fix the material, in preparation for subsequent shaping correction.

[0049] The correction mechanism 22 is used to correct the deformation of the deformed material. The correction mechanism 22 is set in four groups, two by two, respectively set on both sides of the feeding transmission device 1. One group of correction mechanisms 22 corresponds to one end of the material and is used to correct the two groups of materials transmitted.

[0050] like Figure 4 , Figure 5 As shown, the correction mechanism 22 includes a driving component 221, a linkage component 222, and a correction block 223 connected to the linkage component 222. The driving component 221 uses a servo motor, and the four correction mechanisms 22 are driven by four servo motors. Under the drive of the driving component 221, the linkage component 222 moves and drives the correction block 223 to correct the material.

[0051] In order to achieve precise and small correction of the material, the linkage component 222 connecting the servo motor and the correction block 223 is structurally optimized. The design scheme is to design the linkage component 222 as a combination structure of a group of active teeth 2221 and tooth blocks 2222, the active teeth 2221 are meshed with the tooth blocks 2222, the active teeth 2221 are installed on the driving component 221, and the tooth blocks 2222 are movably installed on the mounting blocks set on the frame 21; the connecting part is connected to the correction block 223.

[0052] The tooth block 2222 includes a meshing portion and a connecting portion. The meshing portion is provided with an arc-shaped rack, and the arc of the arc-shaped rack is 5 to 10 degrees.

[0053] According to the structure of the material itself, in order to facilitate the correction of the material, the correction block 223 is installed vertically, the installation surface is a vertical horizontal plane, and the other plane opposite to the installation surface is an inclined surface. The overall design of the correction block 223 is a wedge-shaped structure that is wide at the top and narrow at the bottom.

[0054] Combined with the detailed introduction of the above structural design, the working principle of the utility model is described below:

[0055] During operation, the material is placed between the positioning blocks 101 provided on the upper part of the belt transmission mechanism by the manipulator, and the transmission belt of the belt transmission mechanism transmits the material to between the lifting mechanism 32 and the pressing mechanism 31 of the shaping device 2. After the photoelectric switch provided here detects the material, the belt transmission mechanism stops, and the lifting mechanism 32 is actuated to lift the material transmitted here, so that the material is separated from the transmission belt. At the same time, the pressing mechanism 31 is actuated, the lower pressing plate 312 moves downward, and the pressure head is pressed on the upper part of the material, thereby achieving the lifting and clamping of the material, and then the correction mechanism 22 is actuated to correct the pins of the lithium battery. First, the four servo motors are started at the same time, driving the active teeth 2221 connected to the power output end of the servo motor to rotate, thereby driving the tooth block 2222 to rotate, and the rotation of the tooth block 2222 drives the correction block 223 to move to correct the pins of the lithium battery. During correction, one side of the upper end surface of the correction block 223 first contacts the lithium battery pin, and then approaches the inclined surface for further correction. The correction process adopts the step-by-step application of force from point to surface, and the force is applied steadily and gradually until it fits with the inclined surface of the correction block 223 to complete the correction of the lithium battery pin. After the correction is completed, the correction mechanism 22 stops working, the lifting mechanism 32 descends to re-place the material between the positioning blocks 101 of the transmission belt, and the lower pressing plate 312 of the lower pressing mechanism 31 rises and resets to prepare for the next cycle process, and the lithium battery pin correction operation is repeated in this way.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0057] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
