Description

Technical Field

[0001] The utility model relates to the technical field of solar cells, in particular to a palletizing gripper anti-pressing box mechanism. Background Technique

[0002] In the production of battery wafers, it is necessary to sort them. The sorted battery wafers are usually packed in cartons. In order to facilitate the later transportation and quantity statistics of the battery wafers, the cartons of battery wafers will also be palletized onto pallets and transported and counted in units of pallets. With the development of technology, most factories now use palletizing robots to automatically palletize cartons, and perform full-automatic carton palletizing through preset instructions, which greatly saves manpower.

[0003] Existing palletizing robots generally set palletizing grippers at the working end of a multi-degree-of-freedom robotic arm. The palletizing gripper includes a top plate and clamping plates arranged on the lower end surface of the top plate, and the carton is clamped by reducing the distance between the two clamping plates. Such as Chinese Patent CN202122626112.6, Patent Name: A Mechanical Gripper for Carton-Packaged Products and a Palletizing Robot (see Figure 3 )

[0004] Currently, in the palletizing of battery wafers in cartons, generally, the cartons filled with battery wafers are stacked four layers on the pallet position. When the operator clears the full-load information on the pallet position to empty palletizing information or mistakenly clears it to another pallet position through the control panel, even if there are still a certain number of layers of cartons on the pallet position, the robot will default that the pallet position is empty and continue to run until it reaches the position with materials and stops until it triggers the robot's limit. During this process, the clamped carton descends until it contacts the cartons placed on the pallet position and is blocked from continuing to descend. The downward pressure of the palletizing gripper overcomes the clamping force of its clamping plates on the carton, and the palletizing gripper will continue to press down, resulting in the carton being squeezed by the top plate of the palletizing gripper and causing a pressing box situation. The battery wafers in the carton after being squeezed by the top plate are damaged and fragmented, resulting in defective products. Content of the Utility Model

[0005] The purpose of the utility model is to provide a palletizing gripper anti-pressing box mechanism, which can timely detect and terminate the downward pressure of the palletizing gripper during the continuous palletizing of the palletizing robot when there are a certain number of layers of cartons on the pallet position but the palletizing robot defaults that the pallet position is empty, avoid the top plate squeezing the carton, and reduce the possibility of battery wafer damage and fragmentation.

[0006] To achieve the above object, the technical solution adopted by the utility model is as follows: A palletizing gripper anti-pressing box mechanism, which includes a mounting plate arranged on the top plate of the palletizing gripper. A sliding hole matching with the through hole of the top plate is arranged on the mounting plate. A sliding rod is vertically and slidably connected in the sliding hole. The upper end of the sliding rod is provided with a limiting part whose diameter is larger than the diameter of the sliding hole. Above the top plate, a proximity switch for controlling the emergency stop of the palletizing robot is arranged. After the sliding rod is pushed up from below, the limiting part can trigger the proximity switch.

[0007] A further improvement scheme of the utility model is that the length of the mounting plate is adapted to the width of the top plate. Vertical plates are arranged on both sides of the mounting plate, and the vertical plates are fixed on the top plate by bolts.

[0008] A further improvement scheme of the utility model is that waist holes are arranged on the vertical plates, and the bolts pass through the waist holes to fix the vertical plates to the top plate.

[0009] A further improvement scheme of the utility model is that the proximity switch is arranged on a vertical rod, and the vertical rod is fixed on the top plate.

[0010] A further improvement scheme of the utility model is that the lower end of the sliding rod is provided with a hemispherical head.

[0011] A further improvement scheme of the utility model is that the limiting part is a round tube welded to the upper end of the sliding rod.

[0012] The beneficial effects of the utility model are as follows:

[0013] By arranging the sliding rod, when there are a certain number of layers of cartons on the palletizing position but the palletizing robot defaults that the palletizing position is empty, during the process of the palletizing robot continuing to palletize, the sliding rod moves upward under the action of being pushed and triggers the proximity switch, timely terminating the downward pressure of the palletizing gripper, avoiding the top plate squeezing the cartons, and reducing the possibility of battery chips being damaged or broken.

[0014] By arranging a hemispherical head at the lower end of the sliding rod, the lower end of the sliding rod can be prevented from scratching the cartons during the normal palletizing process.

[0015] By arranging waist holes on the vertical plates and fixing the vertical plates to the top plate with bolts passing through the waist holes, the distance between the mounting plate and the top plate can be adjusted as needed, and further the upward travel required for the limiting part to trigger the proximity switch can be adjusted.

Specific implementation mode

[0020] The present utility model will be further clarified below in conjunction with the accompanying drawings and specific embodiments. Embodiment

[0021] Combined with Figures 1 to 3 As can be seen, a palletizing gripper anti-pressing box mechanism includes a mounting plate 1 provided on the top plate of the palletizing gripper. The mounting plate 1 is provided with a sliding hole 2 that matches the through hole of the top plate. A sliding rod 3 is vertically slidably connected in the sliding hole 2. The upper end of the sliding rod 3 is provided with a limiting part 4 whose diameter is larger than the diameter of the sliding hole 2. Above the top plate, there is a proximity switch 5 for controlling the emergency stop of the palletizing robot. When the sliding rod 3 is pushed upward from below, the limiting part 4 can trigger the proximity switch 5.

[0022] The length of the mounting plate 1 is adapted to the width of the top plate. Vertical plates 6 are provided on both sides of the mounting plate 1, and the vertical plates 6 are fixed to the top plate by bolts 7. Refer to Figure 3 , the clamping plates 12 are located on the left and right sides of the top plate 11. When installing this mechanism, screw holes are provided on the front and rear surfaces of the top plate 11, and the two vertical plates 6 are fixed on the front and rear sides of the top plate 11. The limiting part 4 is slidably connected in the sliding hole 3 of the mounting plate 1 and abuts against the upper end of the mounting plate 1 through the through hole 13 on the top plate 11.

[0023] The diameter of the limiting part 4 is smaller than the diameter of the through hole 13. The limiting part 4 is a circular tube welded to the upper end of the sliding rod 3.

[0024] Waist-shaped holes 8 are provided on the vertical plates 6, and the bolts 7 pass through the waist-shaped holes 8 to fix the vertical plates 6 to the top plate.

[0025] The proximity switch 5 is arranged on the vertical rod 9, and the vertical rod 9 is fixed on the top plate.

[0026] The lower end of the sliding rod 3 is provided with a hemispherical abutting head 10. Preferably, the hemispherical abutting head 10 is an elastic abutting head, preferably made of rubber.

[0027] The working principle of a carton anti-pressing mechanism for a palletizing gripper provided by the utility model is as follows: During use, this mechanism is installed on the top plate of the palletizing gripper. When there are still a certain number of layers of cartons on the palletizing position, but the robot defaults that the palletizing position is empty and continues to operate to a position with materials, after the carton clamped by the palletizing gripper descends to contact the cartons placed on the palletizing position, the clamped carton is blocked from further descending by the lower part, and the downward pressure of the palletizing gripper overcomes the clamping force of its clamping plate on the carton. The palletizing gripper will continue to press down, and relative movement occurs between the carton and the palletizing gripper. The sliding rod 3 on the mounting plate 1 is blocked from further descending by the carton from below and is pushed upward and moves. After moving to a certain extent, it triggers the proximity switch 5, causing the palletizing robot to stop urgently, avoiding the occurrence of the situation where the palletizing gripper further presses down and causes carton pressing.
