Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0041] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0042] The embodiment of the utility model provides a pin welding device, which can help improve production efficiency.

[0043] See also Figures 1 to 9 The pin welding equipment includes: a feeding conveyor belt 1, a handling robot 2, a material moving module 3 and a welding module 4.

[0044] The transport robot 2 is used to transport the product on the feeding conveyor belt 1 to the material transfer module 3, and the material transfer module 3 is provided with a carrying fixture 31 for carrying and positioning the workpiece.

[0045] The welding module 4 is straddled on the material transfer module 3 , and includes a soldering module 41 and a detection camera 42 for detecting the position of pins. The soldering module 41 is used to fix the pins of the workpiece on the supporting fixture 31 by soldering.

[0046] Specifically, the workpiece flows in from the loading conveyor belt 1, and is transferred to the carrying fixture 31 of the material transfer module 3 through the handling robot 2. Then the carrying fixture 31 transfers the positioned workpiece to the welding station of the welding module 4, so as to weld and fix the pins installed on the workpiece.

[0047] In this embodiment, the production efficiency of the workpiece is further improved by improving the automation level of the production equipment. Moreover, by positioning the workpiece first and then transferring the workpiece through the carrying fixture 31, there is no need to worry about the position deviation caused by the handling robot 2 during the handling process, which is conducive to maintaining the welding quality of the product.

[0048] Optionally, the handling robot 2 includes a first gantry 21, a slide rail installed on the first gantry 21, a transfer robot 22 slidably installed on the slide rail, and a first driving device 23 for driving the transfer robot 22 to move along the slide rail; the transfer robot 22 includes a clamping jaw assembly 221 and a first CCD detection camera 222 for detecting workpieces, and the first CCD detection camera 222 is electrically connected to the clamping jaw assembly 221.

[0049] Specifically, the first CCD detection camera 222 detects the position of the carrier carrying the workpiece on the loading conveyor belt 1, and then sends the position information to the handling robot 2. The handling robot 2 adjusts the position of the transfer robot 22 so that the transfer robot 22 can accurately grasp the carrier, thereby transferring the carrier and the workpiece at the same time.

[0050] Optionally, the transfer robot 22 is further provided with an adsorption component 223 for sucking and placing the cover plate; the first gantry 21 is also provided with a first height measuring component 24 for detecting the workpiece. The adsorption component 223 can suck away the cover plate pressing the workpiece on the carrier, and the cover plate is generally a plate pressed on the workpiece to protect the parts that do not need to be processed.

[0051] Optionally, the supporting fixture 31 includes a support frame 331 and a supporting plate 332 rotatably mounted on the support frame 331, and a positioning column for positioning the carrier is provided on the supporting plate 332; a clamping assembly 333 for clamping the workpiece and a telescopic device 334 for adjusting the inclination angle of the supporting plate 332 are also installed on the supporting plate 332.

[0052] Specifically, after the clamping assembly 333 clamps the workpiece, the telescopic device 334 controls the tilt angle of the carrier plate 332 by adjusting the extension length of the telescopic shaft, so that the workpiece on the carrier plate 332 is at a suitable welding angle.

[0053] Optionally, the clamping assembly 333 includes a first clamping arm 51 for clamping the battery compartment of the workpiece and a second clamping arm 52 for clamping the circuit board of the workpiece; the clamping arm is also provided with a first lifting device 53 for driving the first clamping arm 51 to rise and fall and a second lifting device 54 for driving the second clamping arm 52 to rise and fall.

[0054] It should be noted that, in the incoming workpiece and after the pins and circuit board are assembled, the material transfer module 3 needs to weld the pins and circuit board to fix the pins. The pins can be charging pins or pins for other purposes.

[0055] Optionally, the welding module 4 also includes a second gantry 43, and the solder module 41 and the detection camera 42 are both installed on the second gantry 43; the solder module 41 includes a ball supply device 411 for supplying solder balls, a second CCD detection camera 42 for detecting the position of the workpiece, and a laser welding module 412 for welding and connecting solder balls and pins.

[0056] Specifically, the ball supply device 411 supplies balls, so that the solder balls are output from the solder outlet tube, and the laser welding module 412 welds the contact position between the pin and the solder ball when the solder ball and the pin are in contact, thereby forming a solder joint.

[0057] It should also be noted that the pin welding equipment also includes a second height measuring device. During the material moving process of the material moving module 3, the second height measuring device detects the height of the workpiece to facilitate subsequent welding.

[0058] Optionally, a solder lifting module 44 for driving the solder assembly to lift in the vertical direction is also provided on the second gantry 43, so as to realize soldering. In addition, the horizontal position of the solder assembly can be adjusted along the second gantry.

[0059] Optionally, the pin welding equipment further comprises a third gantry 61 straddling the material transfer module 3 , a material unloading robot 62 is mounted on the third gantry 61 , and a contour scanner 63 for detecting the outer contour of the workpiece is disposed on one side of the material unloading robot 62 .

[0060] Specifically, the profile scanner 63 detects whether the weld point formed by welding is full and qualified.

[0061] Optionally, the pin welding equipment further includes an NG handling module 71 and an NG discharging conveyor belt 72 , and the NG handling module 71 is provided with a re-inspection CCD module 73 for detecting NG workpieces.

[0062] The re-inspection CCD module 73 re-performs a visual inspection on the solder joint. If the solder joint is still determined to be insufficient, the NG transport module 71 transfers the workpiece to the NG discharge conveyor belt 72 .

[0063] Optionally, the material transfer module 3 includes three linear modules arranged in parallel, and a bearing fixture 31 is installed on each linear module.

[0064] That is, the material transfer module 3 can flexibly feed materials according to the positions of the supporting fixtures 31 on different linear modules, thereby meeting the material feeding needs of the three material transfer modules 3 and greatly improving the production efficiency.

[0065] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
