Technical Field

[0001] The invention relates to the field of automatic production of storage batteries, and in particular to an online automatic short-circuit detection device for storage batteries. Background Art

[0002] Lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. In the discharge state of lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main components of the positive and negative electrodes are both lead sulfate. Lead-acid battery needs to be short-circuited during the preparation process, and the battery terminals are connected to the power supply for short-circuit test. The prior art CN113884921A discloses a multi-channel short-circuit test device for batteries. After multiple batteries are arranged on a transport roller, they are transported. When they are transported to the insertion cavity, multiple batteries contact the detection pieces of the corresponding detection heads to detect short circuits. This patent is a separate short-circuit detection device, and the subsequent production of batteries is currently carried out in the form of an automated conveyor belt. Multiple batteries need to be limited and placed together for unified power connection testing, and the batteries need to be transferred out after the limit detection is completed. Therefore, a limit mechanism is needed to facilitate the transfer of batteries to adapt to automated production. Therefore, it is urgent to solve this problem. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an online automatic short-circuit detection device for a battery, comprising a workbench, a lifting connection block is arranged above the front of the workbench, a connection head is distributed at the bottom of the connection block to contact the battery terminal, and the connection head is connected to a short-circuit tester to perform a short-circuit test, and a sliding seat that slides forward and backward is arranged on the workbench, and a limited edge is arranged on the top of the sliding seat except the right end for limiting the placement of multiple batteries; a retaining edge is arranged at the bottom of the right end of the connection block, and the sliding seat slides to the bottom of the connection block, and the connection block descends, and the retaining edge and the limiting edge together limit the lower part of the battery placed on the sliding seat;

[0004] A material unloading platform is arranged on the right side of the workbench, and a material unloading conveyor belt is arranged on the rear side of the material unloading platform.

[0005] A further improvement is that the unloading platform is provided with a right pulling mechanism to pull the battery on the sliding seat to the unloading platform, and the unloading platform is also provided with a rear pulling mechanism to pull the battery on the unloading platform to the unloading conveyor belt.

[0006] A further improvement is that a table plate flush with the height of the sliding seat is provided on the top of the unloading table, and the left end of the table plate extends to be close to the sliding seat; the right pulling mechanism includes a right pulling cylinder provided on the front side of the top of the table plate, the left piston rod of the right pulling cylinder is located on the front side of the sliding seat, the left piston rod of the right pulling cylinder is connected to the right pulling plate, and the right pulling plate is initially located above the limiting edge on the left side of the sliding seat.

[0008] A further improvement is that there are two front and rear linear rails on the top of the workbench, the sliding seat is located on the two front and rear linear rails and slides back and forth, the rear side of the sliding seat is connected to the front and rear push-pull cylinders, and the front and rear push-pull cylinders are arranged at the rear end of the workbench.

[0009] A further improvement is that a limit block is provided at the front end of the top of the workbench between the two front and rear linear rails. When the sliding seat is pushed forward by the front and rear push-pull cylinders and contacts the limit block, the power connection head of the power connection block corresponds one by one to the terminals of the battery on the sliding seat.

[0010] A further improvement is that a gantry frame 2 is arranged above the front of the workbench, a push-down cylinder is arranged on the top of the gantry frame 2, and a piston rod at the bottom of the push-down cylinder passes through the gantry frame 2 and is connected to the power connection block.

[0011] Beneficial effects of the present invention: The present invention places multiple batteries by setting a sliding seat that slides forward and backward. The sliding seat limits the three sides of the battery through three limiting edges. The power connection block moves downward so that the retaining edge acts as the fourth limiting edge to stably limit the battery. When the power connection block moves downward to limit, the power connection head connects to the battery terminal for testing. After the test is completed, there is a notch on the right side of the top of the sliding seat, which can smoothly transfer the battery to the unloading table and then to the unloading conveyor belt for unloading, which well meets the needs of automated transfer without the need for additional mechanisms. And only when the retaining edge is completely moved downward to block the battery can it be connected to electricity, thus achieving the effect of error prevention.

[0012] The top of the unloading table of the present invention is provided with a table plate that is flush with the height of the sliding seat. In this way, after the detection is completed, the power block moves back upward, and the right pulling cylinder of the right pulling mechanism is started to drive the right pulling plate to pull all the batteries on the sliding seat through the notch on the right side of the top of the sliding seat to the table plate located on the rear side of the rear pulling plate. This is very smooth and there is no interference in the transfer process; the rear pulling mechanism is set through the gantry, so that the rear pulling cylinder of the rear pulling mechanism is started to drive the rear pulling block of the rear pulling plate to pass through the gantry to load and unload the batteries to the unloading conveyor belt. The ingenious design meets the needs of automated transfer.

[0013] The sliding seat of the present invention is located on two front and rear linear rails and slides through the front and rear push-pull cylinders. In this way, the sliding seat slides to the rear end to place the battery. When it slides to the front end and contacts the limit block, the push-down cylinder is started to make the connection head of the connection block contact the terminal of the battery to perform a short-circuit test. In this way, one end is loaded and the other end is working, which does not interfere with the work and ensures safe operation. BRIEF DESCRIPTION OF THE DRAWINGS
