Detailed Embodiments

[0018] The present utility model will be further described below with reference to the drawings:

[0019] As shown Figures 1 to 3 In the figure, a welding strength detection device for positive and negative electrode lead-out rows includes a frame 01, a workbench 02, a base 03, a mounting bracket 04, a carrier 05, a first pushing cylinder 06, a second pushing cylinder 07, a first pushing block 08 and a second pushing block 09. The workbench 02 is horizontally fixed on the frame 01. The base 03 is fixed above the workbench 02. The mounting bracket 04 is fixed on the upper left side of the base 03. The carrier 05 is fixed on the upper right side of the base 03. A first placement groove is vertically opened above the carrier 05. A through hole is provided on the left side of the carrier 05, and the right end of the through hole communicates with the first placement groove. The first pushing cylinder 06 is fixed on the mounting bracket 04. The second pushing cylinder 07 is fixed on the base 03 and corresponds to the space between the mounting bracket 04 and the carrier 05. The first pushing block 08 is fixed on the power output end of the first pushing cylinder 06 and corresponds to the upper part of the carrier 05. The second pushing block 09 is fixed on the power output end of the second pushing cylinder 07 and corresponds to the inside of the through hole.

[0020] The lead-out row is formed by welding a copper row and an aluminum row, and the copper row and the aluminum row are perpendicular. Therefore, the lead-out row is L-shaped. When the welding strength needs to be detected, the vertical part of the lead-out row is inserted into the first placement groove on the carrier 05, and the horizontal part is placed on the upper end surface of the carrier 05. Then, the second pushing cylinder 07 drives the second pushing block 09 to press the vertical end of the lead-out row to the right in the through hole, and then the first pushing cylinder 06 drives the first pushing block 08 to run to the right, so as to apply a certain pressure to the horizontal part of the lead-out row to the right. If there is no loosening of the horizontal part of the lead-out row, the welding strength is qualified. The advantage of this design is that it can quickly detect the welding strength of the lead-out row, avoid unqualified lead-out rows from being put into subsequent production, and improve product quality.

[0021] In this design, a guiding slide 10 is further included. The left end of the guiding slide 10 is fixed on the mounting bracket 04, and the upper end of the first pushing block 08 is slidably connected to the lower end of the guiding slide 10. By setting the guiding slide 10, the first pushing block 08 can run smoothly to the right, ensuring the accuracy of the pressure applied to the lead-out row.

[0022] In this design, a blanking component 11 is further included. The blanking component 11 includes a pulling cylinder and a pulling plate. The pulling cylinder is fixed above the workbench 02, and the pulling plate is fixed on the power output end of the pulling cylinder. A second placement groove is opened at the upper end of the pulling plate. A blanking hole is provided on the workbench 02. When the pulling cylinder extends, the pulling plate corresponds to the inside of the first placement groove and the second placement groove corresponds to the through hole. When the pulling cylinder retracts, the pulling plate corresponds to the upper part of the blanking hole.

[0023] Before placing the lead-out row to be inspected, the pulling cylinder drives the pulling plate to move forward so that the second placement slot corresponds to the first placement slot, and the second placement slot corresponds to the through hole. When testing the welding strength, the lead-out row is placed in the second placement slot, and the second push block 09 presses the vertical part of the lead-out row. After the inspection is completed, the pulling cylinder drives the pulling plate to move backward and drives the lead-out row backward at the same time. After the lead-out row leaves the first placement slot, it falls into the blanking hole and enters the collection container for collection. By setting the program, it can be set to manually remove qualified products and collect defective products at the blanking hole, or it can be set to manually remove defective products and collect qualified products at the blanking hole.

[0024] In the present design, a protective cover 12 is also included. The protective cover 12 is fixed on the right side of the carrier 05. The left end and the lower end of the protective cover 12 are provided with openings. When the welding strength is unqualified, the horizontal part of the lead-out row will pop out to the right under the pressure of the first push block 08. The protective cover 12 is provided so that the lead-out row entering the protective cover 12 can be discharged from the opening below, thereby avoiding safety hazards caused by the workpiece popping out.

[0025] In the present design, a storage table 13 is also included. The storage table 13 is fixed on the frame 01 and corresponds to the front side of the workbench 02. The storage table 13 can place multiple groups of lead-out rows to be tested for use during testing.

[0026] In the present design, a protective casing 14 is also included. The protective casing 14 is fixed above the workbench 02 and corresponds to the left and right sides and the rear side of the workbench 02, which can prevent the workpiece from falling from the periphery of the equipment during the inspection process.

[0027] In the present design, a control box 15 is also included. The control box 15 is fixed above the mounting bracket 04. The first pushing cylinder 06, the second pushing cylinder 07 and the pulling cylinder are all connected to the control box 15 signal. The control box 15 is used to control the action sequence and timing of the first pushing cylinder 06, the second pushing cylinder 07 and the pulling cylinder.

[0028] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
