Description

Technical Field

[0001] This invention relates to a container punching and locking device, belonging to the field of container production equipment. Background Technology

[0002] In the container manufacturing industry, one of the processes involves drilling hundreds of through holes in the container's base plate and securing them with screws. To drill hundreds of through holes in a single container base plate, the positions are first marked on the plate, then manually drilled one hole at a time using a handheld drill, and finally, screws are driven in manually. Because drilling so many holes and screws manually is inefficient, it's common to need a dozen or more people drilling inside the same container simultaneously, and then another dozen or so people driving in the screws. This increases labor costs and overall production efficiency. Furthermore, manual drilling and screwing are physically demanding.

[0003] Utility model patent application number CN201710459852.0 discloses an automatic container punching machine, including drilling rigs. Its features include a frame and a controller, with driven wheels at each of the four corners of the frame's bottom. The frame comprises an upper frame and a lower frame, with columns connecting corresponding corners of the upper and lower frames. A movable crossbeam, capable of moving back and forth along the two longitudinal sides of the lower frame, has drilling rigs evenly distributed along its longitudinal direction. Both longitudinal sides of the lower frame extend outwards at the same end, with a fixed crossbeam connecting the two extended ends. Drilling rigs are evenly distributed on the fixed crossbeam, with the number of drilling rigs on the fixed crossbeam equal to and corresponding to the number of drilling rigs on the movable crossbeam. Each drilling rig is connected to the controller via wires. Using this automatic container punching machine can reduce labor, increase production efficiency, and lower production costs. However, in existing technologies, the nailing process still requires manual operation, resulting in low production efficiency and high labor intensity.

[0004] Therefore, there is a need for a container drilling and locking device that can automatically drill and lock nails, thereby improving work efficiency and reducing the labor intensity of workers. Summary of the Invention

Detailed Implementation

[0019] like Figure 1-16 As shown, a container punching and locking device in this embodiment includes a frame 1, a control panel 5 on the frame 1, a displacement mechanism 2 at the bottom of the frame 1 for driving the frame 1 to move, guide mechanisms 4 on both the front and rear sides of the frame 1 for positioning the frame 1 within the container along the width direction, and multiple sets of actuators 3 on the frame 1 distributed along the left and right directions for automatic punching and locking. The displacement mechanism 2 includes a drive wheel set 21 and a driven wheel set 22. Both the drive wheel set 21 and the driven wheel set 22 are located at the bottom of the frame 1. The drive wheel set 21 is driven by a displacement motor 23. When the displacement motor 23 is started, the drive wheel set 21 rotates, thereby moving the frame 1 into the container. During the movement of the frame 1, the driven wheel set 22 rotates. In actual operation, the drive wheel set 21 and the driven wheel set 22 can be connected by a chain to increase the friction between the drive wheel set 21 and the ground and the friction between the driven wheel set 22 and the ground when the frame 1 stops moving. This is to prevent the frame 1 from sliding due to inertia when it stops moving, which could lead to inaccurate positioning. The guiding mechanism 4 includes a guide seat 41, on which a plurality of guide wheels 42 are provided. The plurality of guide wheels 42 are evenly distributed from left to right. A guide cylinder 43 is connected to the guide seat 41. The guide cylinder 43 drives the guide seat 41 to move back and forth. After the frame 1 moves into the container, the guide cylinder 43 is activated, causing the front guide seat 41 to move forward and the rear guide seat 41 to move backward. In this way, the guide wheels 42 on the front guide seat 41 abut against the inner wall of the front side of the container, and the guide wheels 42 on the rear guide seat 41 abut against the inner wall of the rear side of the container. In this way, the frame 1 is positioned in the back and forth direction, which achieves the effect of guiding the movement of the frame 1. The actuator 3 includes a movable frame 31, which is slidably connected to the frame 1. Two movable components 32 are provided on the movable frame 31, which are arranged front to back. The movable components 32 drive the movable frame 31 to move left and right on the frame 1. The movable frame 31 is provided with an adjustment component 33 and multiple connecting frames 34, which are evenly distributed from front to back. The connecting frames 34 are slidably connected to the movable frame 31. The adjustment component 33 drives the connecting frames 34 to move back and forth on the movable frame 31, thereby adjusting the distance between two adjacent actuators. The connecting frame 34 is provided with an upper nail component 35, a drilling component 36, and a lower nail component 37. The moving component 32 includes a rotating shaft 32.1, two first gears 32.2, and two first racks 32.3. The two first racks 32.3 are distributed vertically and are parallel to the left-right direction. The first racks 32.3 are fixedly mounted on the frame 1. The rotating shaft 32.1 is vertically arranged and rotatably connected to the frame 1 through a bearing 32.4. The two first gears 32.2 are respectively mounted at both ends of the rotating shaft 32.1 and mesh with the two first racks 32.3 respectively. The rotating shaft 32.1 is driven by a moving motor 32.5. When the moving motor 32.5 is started, the rotating shaft 32.1 rotates, which drives the first gears 32.2 to rotate on the first racks 32.3, thereby driving the moving frame 31 to move left or right on the frame 1, thereby adjusting the distance between two adjacent moving frames 31, that is, adjusting the drilling spacing in the left-right direction. The nail-attaching assembly 35 includes a hopper 35.1, a nail-dropping pipe 35.2, a conveying track 35.3, a nail-grabbing unit 35.4, and a pushing unit 35.5. The nail-dropping pipe 35.2 is vertically arranged. The nail-dropping pipe 35.2, the hopper 35.1, and the conveying track 35.3 are all fixedly connected to the connecting frame 34. The top of the hopper 35.1 is open. The conveying track 35.3 is inserted from one side of the hopper 35.1. The top of the conveying track 35.3 is provided with a groove 35.6, which extends to both ends of the conveying track 35.3. The outer end of the conveying track 35.3 is hinged with an opening and closing plate. 35.7 The opening and closing plate 35.7 is elastically connected to the conveying track 35.3. The pushing unit 35.5 is located at the bottom of the hopper 35.1. The pushing unit 35.5 is used to push the screws in the hopper 35.1 into the slide groove 35.6. A direct vibration feeder 35.8 is provided below the conveying track 35.3. The direct vibration feeder 35.8 is located on the side of the hopper 35.1 near the conveying track 35.3. The nail grabbing unit 35.4 is located at the outer end of the conveying track 35.3. The nail grabbing unit 35.4 is used to grab the screws at the opening and closing plate 35.7 and put them into the nail dropping tube 35.2. The nail-grabbing unit 35.4 includes a gripper 35.41, which is driven by a clamping cylinder 35.42. The clamping cylinder 35.42 moves horizontally via an upper nail cylinder 35.43. The pushing unit 35.5 includes a pushing cylinder 35.51, which is located below the hopper 35.1. The piston end of the pushing cylinder 35.51 is fixedly connected to two symmetrically arranged pushing plates 35.52. The pushing cylinder 35.51 drives the pushing plates 35.52 to rise and fall. The pushing plates 35.52 are inserted from the bottom of the hopper 35.1. The conveying track 35.3 is located between the two pushing plates 35.52. The top of the pushing plates 35.52 is a slope, and the two slopes form an inverted V-shape. After the screw is placed into the hopper 35.1, the two pusher plates 35.52 are driven to reciprocate up and down by the pusher cylinder 35.51. When the pusher plate 35.52 rises, it pushes the screw up. When the inclined plane is higher than the conveyor track 35.3, the screw at the inclined plane slides into the groove 35.6 of the conveyor track 35.3. In fact, the width of the groove 35.6 is smaller than the diameter of the screw head, and the width of the groove 35.6 is larger than the diameter of the screw thread section, so that the screw thread section is inserted into the groove 35.6, while the screw head abuts against the top of the conveyor track 35.3. At the same time, the direct vibration feeder 35.8 is activated, causing the screw in the groove 35.6 to move to the outer end of the conveyor track 35.3 and abut against the opening and closing plate 35.7. Then, the clamping cylinder 35.42 causes the jaws 35.41 to clamp the screw, and the clamping cylinder 35.42 is driven by the upper nail cylinder 35.43. The movement of the clamping cylinder 35.42 drives the screw to move via the gripper 35.41, which in turn pushes the opening and closing plate 35.7 to open. In fact, the opening and closing plate 35.7 is connected to the conveying track 35.3 via a torsion spring. At this time, the torsion spring deforms under force. When the screw held by the gripper 35.41 separates from the opening and closing plate 35.7, the elastic action of the torsion spring causes the opening and closing plate 35.7 to close. The next screw on the conveying track 35.3 is then conveyed to the opening and closing plate 35.7. The movement of the clamping cylinder 35.42 at any time moves the screw on the gripper 35.41 to the top of the nail drop tube 35.2. Then, the gripper 35.41 is released, allowing the screw to fall into the nail drop tube 35.2 and be conveyed downward to the nail lowering assembly 37 for nailing. Afterward, the nail uppering cylinder 35.43 drives the clamping cylinder 35.42 to move in the opposite direction to achieve a reset. In this way, the automatic feeding of screws is realized. The drilling assembly 36 includes a drilling motor 36.1 and a drill bit 36.2 distributed vertically. The drilling motor 36.1 is connected to the drill bit 36.2 through a first power head 36.3, which is vertically arranged. A positioning sleeve 36.4 is fitted onto the drill bit 36.2. The positioning sleeve 36.4 is connected to the first power head 36.3. A gap is provided between the positioning sleeve 36.4 and the drill bit 36.2. During drilling, the drilling motor 36.1 starts and drives the drill bit 36.2 to rotate synchronously. The first power head 36.3 moves the drill bit 36.2 downward to drill the bottom plate. After drilling is completed, the first power head 36.3 can be raised. In addition, the positioning sleeve 36.4 can not only press down the bottom plate of the container to prevent the bottom plate from warping and affecting the drilling effect, but also determine the drilling depth and play a positioning role. The screw-down assembly 37 includes a second power head 37.1, a screwdriver bit 37.2, and a screw-receiving unit 37.3. The second power head 37.1 and the screwdriver bit 37.2 are arranged vertically, and both are vertically positioned. The screwdriver bit 37.2 is located at the bottom end of the second power head 37.1. The screw-receiving unit 37.3 is located below the screw-down tube 35.2 and is used to move the screw inside the screw-down tube 35.2 into the drilled hole. The nail-attaching unit 37.3 includes a nail-attaching frame 37.31, a nail-locking clamp 37.32, a nail-attaching tube 37.33, a sliding nail track 37.34, and a lifting frame 37.35. The nail-attaching tube 37.33 is coaxially and fixedly mounted at the bottom end of the nail-attaching tube 35.2. The nail-locking clamp 37.32 is located directly below the bit 37.2. The nail-attaching frame 37.31 is fixedly mounted on one side of the nail-locking clamp 37.32. The sliding nail track 37.34 is inclinedly mounted on the other side of the nail-locking clamp 37.32. Both the nail-locking clamp 37.32 and the sliding nail track 37.34 are located below the nail-attaching tube 37.33. The lifting frame... 37.35 is fixedly mounted on the sliding nail track 37.34. The nail receiving tube 37.33 passes through the lifting frame 37.35 and is connected to the lifting frame 37.35 via a first spring 37.36. Guide rods 37.37 are vertically fixed on both the front and rear sides of the nail receiving frame 37.31. The guide rods 37.37 pass through the connecting frame 34 and are elastically connected to the connecting frame 34 via a second spring 37.38. A pushing component 37.39 is provided at the bottom of the second power head 37.1, and the pushing component 37.39 is located above the nail receiving frame 37.31. The pushing component 37.39 includes a lifting ring 37.391 and a pushing ring 37.392. The lifting ring 37.391 is fixedly sleeved on the bottom end of the second power head 37.1. The pushing ring 37.392 is located below the lifting ring 37.391. A plurality of connecting rods 37.393 are vertically fixedly arranged on the top of the pushing ring 37.392. The plurality of connecting rods 37.393 are evenly distributed circumferentially around the bit 37.2. A third spring 37.394 is sleeved on the connecting rod 37.393. The third spring 37.394 is located between the pushing ring 37.392 and the lifting ring 37.391. The two ends of the third spring 37.394 are respectively fixedly arranged on the pushing ring 37.392 and the lifting ring 37.391. After drilling is completed, the moving frame 31 moves the screwdriver bit 37.2 to directly above the drilled hole. At this time, the screw in the screw drop tube 35.2 is discharged from the bottom and conveyed to the screw receiving tube 37.33. The screw in the screw receiving tube 37.33 is discharged from the bottom and falls into the sliding screw track 37.34. The screw on the sliding screw track 37.34 then slides into the locking clip 37.32, which secures the screw. The second power head 37.1... The top of the screwdriver bit 37.2 is connected to a drive source, which rotates the bit 37.2. Simultaneously, the second power head 37.1 drives the bit 37.2 and the lifting ring 37.391 to descend. The descent of the lifting ring 37.391, via the third spring 37.394, drives the push ring 37.392 to descend synchronously. When the push ring 37.392 abuts against the top of the nail holder 37.31, the first spring 37.36 and the two second springs 37.38... The sum of the elastic strengths is less than the sum of the elastic strengths of the multiple third springs 37.394. Therefore, when the push ring 37.392 continues to descend, it drives the nail receiving frame 37.31, the nail locking clamp 37.32, the sliding nail track 37.34, and the lifting frame 37.35 to descend synchronously, causing the first spring 37.36 and the second spring 37.38 to deform. When the screw on the nail locking clamp 37.32 is inserted into the drilled hole and cannot move further downward, the descent of the push ring 37.392 cannot drive the push ring 37.392 to descend. This causes relative movement between the lifting ring 37.391 and the connecting rod 37.393, reducing the distance between the lifting ring 37.391 and the push ring 37.392, and causing the third spring 37.394 to deform. When the bit 37.2 is inserted into the screw hole, the rotation of the bit 37.2 drives the screw to rotate synchronously, thus screwing the screw into the drilled hole and achieving automatic nailing. After nailing is completed, the second power head 37.1 drives the bit 37.2 to rise and reset. The elastic action of the first spring 37.36 and the second spring 37.38 resets the nail receiving frame 37.31, the nail locking clamp 37.32, the sliding nail track 37.34 and the lifting frame 37.35. The elastic action of the third spring 37.394 causes the lifting ring 37.391 and the connecting rod 37.393 to move in opposite directions, and increases the distance between the lifting ring 37.391 and the pushing ring 37.392. Here, the drive source connected to the second power head 37.1 can be a separate motor, or it can be a synchronous belt. The drilling motor 36.1 is connected to the second power head 37.1 through the synchronous belt. During the start-up of the drilling motor 36.1, the second power head 37.1 drives the bit 37.2 to rotate through the synchronous belt. In this way, the number of motors used is reduced and the cost is reduced. The adjustment assembly 33 includes a second rack 33.1 and multiple adjustment motors 33.2. The second rack 33.1 is parallel to the front-back direction and is fixedly mounted on the movable frame 31. The multiple adjustment motors 33.2 correspond one-to-one with multiple connecting frames 34. The housing of the adjustment motor 33.2 is fixedly mounted on the connecting frame 34. A second gear 33.3 is mounted on the adjustment motor 33.2. The second gear 33.3 meshes with the second rack 33.1. When the adjustment motor 33.2 is started, it drives the second gear 33.3 to rotate on the second rack 33.1, thereby driving the connecting frame 34 to move back and forth on the movable frame 31, thus realizing the adjustment of two adjacent perforation positions in the front-back direction, which is convenient for containers of different specifications. In addition, each cylinder and each motor is electrically connected to the PLC, and automation is achieved through PLC control; Among them, the number of actuators 3 is 2 to 15, and the number of connecting frames 34 on the same actuator 3 is 2 to 8; In summary, this invention achieves automatic drilling and nailing, improving work efficiency and reducing worker labor intensity. By adjusting the positions of two adjacent drill bits 36.2 in the front-back and left-right directions, it achieves row spacing compatibility and is suitable for containers of different specifications. Furthermore, by abutting the guide wheels 42 against the sides inside the container, it achieves automatic width and front-back positioning after entering the container, thereby improving drilling and nailing accuracy. In addition, by raising and lowering the second power head 37.1, it simultaneously controls the asynchronous raising and lowering of the bit 37.2 and the nail clamp 37.32, reducing nailing time and improving automatic nailing efficiency. In addition to the above embodiments, the present invention also includes other embodiments. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
