Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, in particular to a nail pulling machine. Background Art

[0002] Secondary batteries need to be kept at high temperature after injection and before formation. During this process, temporary glue nails need to be inserted into the injection port to ensure that the battery is in a sealed state and complete the corresponding production process. The injection hole of the battery needs to be connected to the rubber nozzle in the vacuum pipeline of the formation equipment during the formation process to form a gas circuit, so that the gas generated during the formation process can be smoothly discharged from the inside of the battery and the electrolyte will not overflow as much as possible, thereby ensuring the formation quality and reducing the scrap rate of products in the formation stage. Therefore, it is required that all temporary glue nails inserted after the first injection must be pulled out before formation.

[0003] In the prior art, most of the nails on the battery are removed by automatic nail removal equipment. Since the jaws of the automatic nail removal equipment are mostly made of rubber, the electrolyte overflow and corrosion during the nail removal process cause aging and a decrease in the friction coefficient, so that some nails are not pulled out from the battery body. If these nails of the battery body that have not been pulled out enter the formation process together with the battery body, the battery product will inevitably be scrapped. Utility Model Content

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0046] Embodiment 1:

[0047] This embodiment provides a nail pulling machine, including:

[0048] Rack 1;

[0049] A nail removing device, the nail removing device comprises a clamping mechanism 2 and a three-coordinate moving mechanism 3, the three-coordinate moving mechanism 3 is mounted on the frame 1 and is used to drive the clamping mechanism 2 to move along the X direction, the Y direction and the Z direction;

[0050] A feeding device 4, the feeding device 4 is arranged on the frame 1 and is located below the nail removal device, and the feeding device 4 is used to transport the restraint tray 8 with the batteries 9 placed thereon;

[0051] A material collecting device 5, which is arranged on the frame 1 and is used to hold the removed plastic nails 10;

[0052] The detection mechanism 6 is used to detect whether the rubber nail 10 clamped by the clamping mechanism 2 is complete.

[0053] In this technical solution, the restraint tray 8 with the battery 9 is transported to the feeding device 4 on the frame 1, and the feeding device 4 is used to transport the restraint tray 8 to the bottom of the clamping mechanism 2. Then the three-coordinate moving mechanism 3 drives the clamping mechanism 2 to move along the X direction, the Y direction and the Z direction. After the clamping mechanism 2 clamps the glue nail 10, the three-coordinate moving mechanism 3 drives the clamping mechanism 2 to rise along the Z direction to pull the glue nail 10 out of the battery 9.

[0054] After the clamping mechanism 2 pulls out the plastic nail 10, the three-coordinate moving mechanism 3 drives the clamping mechanism 2 to clamp the plastic nail 10 and move it to the detection mechanism 6. The detection mechanism 6 detects the plastic nail 10 clamped by the clamping mechanism 2. If the pulled out plastic nail 10 is complete, the clamping mechanism 2 clamps the plastic nail 10 and transports it to the collection device 5 to collect the plastic nail 10; if the pulled out plastic nail 10 is incomplete, the detection mechanism 6 will alarm and prompt the staff to handle it.

[0055] In summary, the detection mechanism 6 can detect the glue nail 10 pulled out by the clamping mechanism 2 and identify whether the glue nail 10 on the battery 9 is completely pulled out, thereby avoiding broken nails remaining on the liquid filling port of the battery 9 and preventing the subsequent production process of the battery 9 from being affected.

[0056] Embodiment 2:

[0057] This embodiment provides a nail puller, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0058] Furthermore, the clamping mechanism 2 further comprises:

[0059] The mounting bracket 21 is driven by the three-coordinate moving mechanism 3 and moves along the X, Y and Z directions;

[0060] A variable pitch component, the variable pitch component can be mounted on the mounting bracket 21 in a variable pitch adjustable manner;

[0061] A variable pitch drive assembly, wherein the variable pitch drive assembly is used to drive the variable pitch assembly to achieve variable pitch adjustment;

[0062] A plurality of clamping members 22 are arranged and mounted on the distance-changing assembly, and the distance between adjacent clamping members 22 is adjusted by the distance-changing assembly.

[0063] In this technical solution, the three-coordinate moving mechanism 3 drives the mounting bracket 21 to move along the X, Y and Z directions, thereby driving the variable pitch assembly and the variable pitch driving assembly on the mounting bracket 21 to move, and then driving the plurality of clamps 22 on the variable pitch assembly to move.

[0064] It is worth mentioning that the spacing between each glue nail 10 on the incoming battery 9 is equal, but since each incoming material may be a different type of restraint tray 8 and battery 9, the spacing between the glue nails 10 on each incoming battery 9 is not fixed. A number of clamps 22 are installed on the variable distance component in an equidistant arrangement along the Y direction, and the variable distance drive component is used to drive the variable distance component to work, so as to adjust the distance between adjacent clamps 22 to meet the different spacing sizes of the incoming glue nails 10.

[0065] Furthermore, the variable pitch assembly includes:

[0066] A plurality of slides, wherein the plurality of slides are arranged and mounted on the mounting bracket 21 so as to be movable along the Y direction, and one of the slides is fixedly mounted on the mounting bracket 21;

[0067] A variable pitch connecting rod 25, wherein the variable pitch connecting rod 25 is used for connecting a plurality of the slides;

[0068] Each of the clamping members 22 is correspondingly mounted on each of the slides, and the variable pitch drive assembly is used to drive the movable slide to adjust the variable pitch on the mounting bracket 21 .

[0069] In the present technical solution, a slide rail structure is provided on the mounting bracket 21, one of the slides among the plurality of slides is a fixed slide 24 installed and fixed on the slide rail of the mounting bracket 21, and the remaining slides are movable slides 23 which can be slidably arranged on the slide rail on the mounting bracket 21 along the Y direction, a clamping member 22 is provided below the movable slide 23 and the fixed slide 24, a variable distance connecting rod 25 is provided above the movable slide 23 and the fixed slide 24, and each slide is connected together by the variable distance connecting rod 25.

[0070] Pitch connecting rod 25 Figure 3 As shown, it is composed of a number of long strips and four short strips. The long strips are grouped in pairs, and the two long strips are cross-arranged and hinged together. Then each group of long strips is hinged together; one end of the two short strips is hinged together, and the other end is hinged to the end of the long strip, thereby forming a diamond hinge telescopic mechanism.

[0071] The hinge between the two short strips is connected with a slide, and the cross hinge of each set of long strips is also connected with a slide. The fixed slide 24 remains stationary, and when the movable slide 23 slides, it will drive the diamond hinge telescopic mechanism to telescope, and the telescopic dimensions of each diamond structure are the same, so as to ensure that the spacing between each slide is the same, and then the spacing between each clamping member 22 remains the same, so as to achieve equal distance adjustment between adjacent clamping members 22.

[0072] Furthermore, the variable pitch drive assembly comprises:

[0073] Screw module 26;

[0074] A connecting member 27, wherein the connecting member 27 is mounted on the screw module 26 and driven by the screw module 26 to achieve Y-direction movement;

[0075] The connecting member 27 is also connected to one of the movable slides.

[0076] In the present technical solution, the variable pitch drive assembly is composed of a connecting member 27 and a driving member. One end of the connecting member 27 is connected to one of the movable slides 23, and the other end is connected to the driving end of the driving member. The driving member can be a cylinder, an electric cylinder, or a screw module 26, which can drive the movable slide 23 to slide a certain distance. Preferably, the screw module 26 is used to achieve high-precision transmission, so that the moving distance of the slide can be accurately controlled, thereby making the spacing adjustment between the clamping members 22 more accurate; at the same time, the screw is quiet and stable, which effectively reduces the noise generated when the nail puller is working, and is highly practical.

[0077] Embodiment 3:

[0078] This embodiment provides a nail puller, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0079] Furthermore, the material collecting device 5 is a nail collecting box, and the detection mechanism 6 is installed on the opening of the nail collecting box.

[0080] In this technical solution, the three-coordinate moving mechanism 3 controls the clamping mechanism 2 to clamp the plastic nail 10 and move it to the detection mechanism 6 for detection. After the detection is completed, the clamping mechanism 2 directly releases the plastic nail 10 and allows the plastic nail 10 to fall into the nail collection box for collection.

[0081] Furthermore, the detection mechanism 6 is a photoelectric detector. There are several groups of photoelectric detectors, and the number is consistent with the number of clamping members 22. The spacing between each group of photoelectric detectors is the same as the spacing between each clamping member 22. When the photoelectric detector is working, each group of photoelectric detectors reflects light, and then the clamping member 22 clamps the glue nail 10 and is controlled by the three-coordinate moving mechanism 3 to move to a specified position. If the end of the glue nail 10 blocks the reflected light, it means that the glue nail is completely removed. If the reflected light of the photoelectric detector is not blocked, it means that the glue nail 10 is not completely removed or has not been removed, so an alarm is issued to prompt the staff to handle it.

After the recognition mechanism 7 takes a photo and calculates the spacing of the glue nails 10, the variable pitch drive assembly then controls the slide to move to the required spacing, completes the spacing adjustment between the clamps 22, and finally uses the clamps 22 to remove the glue nails 10.
