Description

Technical Field

[0001] The utility model relates to the field of lithium battery manufacturing, in particular to a square lithium battery jaw device. Background Art

[0002] At present, the country vigorously promotes new energy, and the lithium battery industry has also developed greatly. In this context, the requirements for the production efficiency and quality of lithium batteries are increasing day by day, especially in the process of packaging and detecting square lithium batteries. In the automated battery production process, battery jaws are often used to grab and transport batteries. Some lithium batteries are very heavy by themselves, and the friction required for the jaws to grab the batteries is relatively high. In order to ensure the stability during grabbing and the integrity of battery packaging, high requirements are imposed on the jaw mechanism for grabbing batteries. At present, a large number of jaw mechanisms in the industry rely on jaw cylinders to apply high pressure to the batteries through two jaws to generate friction to bear the weight of the batteries. This solution is suitable for batteries with relatively small weights. When the battery quality is large, this solution will seriously affect the service life of the jaw cylinders, and the risk of falling off during the process of grabbing and moving the batteries will also increase accordingly, and the risk of production accidents will also increase accordingly.

[0004] The square lithium battery jaw device includes a jaw fixing plate. Define the extending direction of the jaw fixing plate as the left-right direction, and the direction perpendicular to the left-right direction horizontally as the front-back direction. The top of the jaw fixing plate is connected to an external robotic arm. The lower surfaces of the left and right ends of the jaw fixing plate are respectively connected with a lifting guide rail bottom plate. Define the side of the two lifting guide rail bottom plates close to each other as the inner side, and the side far from each other as the outer side. An elevating guide rail is provided on the inner side of each of the lifting guide rail bottom plates. A slidable slider connecting plate is provided on each of the elevating guide rails. The middle part of the jaw fixing plate is connected to the lower cylinder mounting plate through two vertical guide shafts, and the cylinder mounting plate is connected to the slider connecting plates on the left and right sides. A linearly extending linear guide rail is respectively connected to the bottom of the slider connecting plates, and a jaw sub-rail is respectively connected to the bottom of the linear guide rails. Compression springs are sleeved on the guide shafts. A jaw cylinder is connected to the bottom of the cylinder mounting plate, and a connecting block is respectively provided on the left and right sides of the bottom of the jaw cylinder. The bottom of the left connecting block is connected to the left jaw sub-rail, and the bottom of the right connecting block is connected to the right jaw sub-rail. A jaw slider is provided at the bottom of each of the jaw sub-rails. A buffer pressing block is provided on the inner side of the jaw slider, and a vertical battery jaw is provided on the outer side. A sensor mounting sheet metal is connected to the right lifting guide rail bottom plate, and a laser sensor is provided on the sensor mounting sheet metal. A photoelectric sensor is provided on the left lifting guide rail bottom plate, and the photoelectric sensor is connected to the bottom of the slider connecting plate through an overpressure sensing piece.

[0005] More specifically, a sensor mounting sheet metal is connected to the bottom of the jaw cylinder, and a diffuse reflection sensor is provided at the bottom of the sensor mounting sheet metal for detecting whether the external battery is dislocated during the clamping and handling process.

[0006] More specifically, an air pipe joint is provided on the right side of the jaw cylinder.

[0008] More specifically, a layer of rubber pads is provided on the inner sides of the battery jaws.

[0009] The working steps of the present utility model include:

[0010] 1. The external robotic arm moves the battery jaws to the top of the external battery tray by pulling the jaw fixing plate, and the laser sensor detects whether there is a battery at the grasping position.

[0011] 2. After detecting that there is a battery at the grasping position, the jaw cylinder opens to separate the left and right battery jaws, and the external mechanical part pulls the battery jaws down.

[0012] 3. The buffer pressing block contacts the upper end of the battery as the battery jaws descend. If the descent is excessive, the slider connecting plate is pushed by the buffer pressing block to slide upward significantly along the lifting guide rail; the overpressure sensing piece is pressed and rises, so that the photoelectric inductor receives a signal, the system alarms, and the downward movement of the battery jaws stops.

[0013] 4. After the battery jaws descend to the preset height, the jaw cylinder closes to drive the battery jaws to clamp the battery; the battery jaws rise under the traction of the external robotic arm to remove the battery from the battery tray; during the clamping process, if the diffuse reflection sensor does not detect the battery, it means that the battery is dislocated during the clamping and handling process, the system alarms, and the action stops.

[0014] 5. The battery jaws release and drop the battery on the designated station conveyor line, and the action is completed.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: relying on the jaw sub-rail and the linear guide rail to disperse the force generated by the battery on the battery jaws, effectively reducing the wear on the battery jaws and the jaw cylinder itself, and improving the service life of the mechanism; at the same time, the combination of the jaw slider and the jaw sub-rail applies force to the battery more difficult to be excessive, and can better protect the battery.
