Description

Technical Field

[0001] This utility model belongs to the field of shelf panel processing technology, and in particular relates to a welding device for forming shelf panels. Background Technology

[0002] In warehousing, logistics, industrial storage, and retail, shelving serves as the core equipment for carrying goods, and its structural stability and load-bearing capacity directly determine the safety and space utilization of stored goods. Shelf shelves, as the core load-bearing components of shelving, must possess sufficient resistance to bending and collapse to accommodate the long-term storage needs of goods of varying weights and sizes. To enhance the structural strength of shelf shelves, the industry commonly employs a process of welding reinforcing ribs to the back of the shelves. This rigid connection between the reinforcing ribs and the shelf panels disperses the localized pressure of the loads on the shelves, preventing deformation or breakage due to long-term stress and extending the overall service life of the shelving.

[0003] Currently, the placement of reinforcing ribs relies on manual judgment or simple marking, which is prone to spacing errors due to hand tremors and visual deviations. This can cause imbalances in the stress on the shelves, with excessively large spacing leading to deformation and insufficient spacing wasting materials and potentially affecting the adaptability of subsequent shelving assembly. Furthermore, manually picking and positioning each reinforcing rib individually is inefficient and cannot meet the needs of large-scale production. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for forming shelf panels, so as to overcome at least one of the above-mentioned defects in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The first conveyor roller group, the second conveyor roller group, and the stand are arranged sequentially from left to right. The conveying direction of the first conveyor roller group is perpendicular to the conveying direction of the second conveyor roller group. A feeding platform is provided in front of the second conveyor roller group, and a clamping assembly is provided below the second conveyor roller group. The clamping end of the clamping assembly... It can pass through the second conveyor roller group and extend above the second conveyor roller group. The top of the upright is fixed with a Y-axis linear module. The moving end of the Y-axis linear module is fixed with a mounting frame. The Z-axis linear module is fixed to the mounting frame. The moving end of the Z-axis linear module is fixed with a pitch-changing module. The pitch-changing module has several moving ends that are spaced apart to the left and right. The bottom end of each moving end is fixed with a first mounting plate. The bottom of the first mounting plate is fixed with a finger cylinder. The top of the first mounting plate is fixed with a telescopic cylinder. The bottom end of the telescopic cylinder passes through the first mounting plate and is fixed with a welding head. The welding head is located in front of the finger cylinder.

[0007] Preferably, the clamping assembly includes a lifting platform, a second mounting plate, a servo motor, a screw, a bearing housing, a guide rail, a slider, a connecting rod, a nut, a third mounting plate, and a clamping plate. The top of the lifting platform is fixed with the second mounting plate. From left to right, the top of the second mounting plate is provided with the bearing housing, the guide rail, and the servo motor. The left end of the servo motor is connected to the screw, and the left end of the screw is inserted into the bearing housing. The screw has two threaded sections with opposite thread directions, and each threaded section is screwed with a nut. The top of the nut is fixed with the third mounting plate, and the top of the third mounting plate is fixed with the clamping plate. The top of the guide rail is slidably connected with two sliders, and the two sliders are respectively connected to two nuts through the connecting rod.

[0008] Preferably, the inner side of the clamp has a pad.

[0009] Preferably, there are several clamping plates, which are distributed at intervals along the length of the third mounting plate.

[0010] Preferably, the second conveying roller group includes several rollers spaced apart front and rear, with clearance space between adjacent rollers, through which the clamping plate can pass.

[0011] Preferably, the top of the feeding platform has a feeding trough, the rear end of the feeding trough has a limiting wall, and the front end of the feeding trough penetrates the front side wall of the feeding platform.

[0012] Preferably, the top of the feeding platform on both the left and right sides of each feeding trough has a clearance groove, which is connected to the feeding trough.

[0013] Preferably, the clearance groove is located in the middle of the discharge trough.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the collaboration of the variable pitch module, Y-axis / Z-axis linear module and clamping components, the precise gripping, variable pitch and welding of reinforcing ribs can be achieved. This not only solves the problems of spacing error and low efficiency of manual operation, but also ensures the quality of the shelf and the stability of the rack, improves the safety of operation, and can adapt to different specifications of shelf, reducing equipment costs and reliance on manual labor.

[0016] 2. The clamping assembly is driven by a servo motor-driven screw, which works with the guide rail slider through the reverse thread section to achieve high-precision synchronous movement of the clamping plate. It can accurately center and stably clamp the shelf to ensure welding accuracy, and can be adapted to different shelf lengths without replacing parts, thus improving the versatility of the device.

[0017] 3. The feeding platform uses the horizontal limit of the feeding groove and the vertical positioning of the limit wall to keep the reinforcing ribs in a uniform posture to improve the accuracy of subsequent welding spacing. The central clearance groove avoids the path of the finger cylinder claw to ensure that the claws stably hold the reinforcing ribs, avoid collisions and falling off, and ensure the stability of feeding.

[0027] like Figures 1 to 6As shown, this embodiment provides a welding device for forming shelf panels, including a first conveyor roller group 1, a second conveyor roller group 3, a clamping assembly 4, a stand 2, a Y-axis linear module 5, a mounting frame 6, a Z-axis linear module 7, a variable pitch module 8, a first mounting plate 9, a finger cylinder 10, a telescopic cylinder 11, a welding head 12, and a feeding platform 13. The first conveyor roller group 1, the second conveyor roller group 3, and the stand 2 are arranged sequentially from left to right. The conveying direction of the first conveyor roller group 1 is perpendicular to the conveying direction of the second conveyor roller group 3. A feeding platform 13 is arranged in front of the second conveyor roller group 3, and a clamping assembly 4 is arranged below the second conveyor roller group 3. The clamping assembly 4 clamps... The holding end can pass through the second conveying roller group 3 and extend above the second conveying roller group 3. The top of the upright frame 2 is fixed with a Y-axis linear module 5. The moving end of the Y-axis linear module 5 is fixed with a mounting frame 6. The Z-axis linear module 7 is fixed to the mounting frame 6. The moving end of the Z-axis linear module is fixed with a variable pitch module 8. The variable pitch module 8 has several moving ends that are spaced apart to the left and right. The bottom end of each moving end is fixed with a first mounting plate 9. The bottom of the first mounting plate 9 is fixed with a finger cylinder 10. The top of the first mounting plate 9 is fixed with a telescopic cylinder 11. The bottom end of the telescopic cylinder 11 passes through the first mounting plate 9 and is fixed with a welding head 12. The welding head 12 is located in front of the finger cylinder 10.

[0028] First, the shelf panel is horizontally conveyed to the first conveyor roller group 1. When the shelf panel reaches the welding station, the clamping component 4 located below the second conveyor roller group 3 is activated. Its clamping end extends upward through the gap of the second conveyor roller group 3, firmly fixing the shelf panel and preventing displacement during welding. The operator pre-places the reinforcing ribs on the feeding table 13. Then, the Y-axis linear module 5 drives the mounting frame 6 to move, aligning the finger cylinder 10 below with the reinforcing ribs on the feeding table 13. Next, the Z-axis linear module 7 drives the variable pitch module 8 to descend, and the finger cylinder 10 closes to grasp the reinforcing ribs. After grasping, the variable pitch module 8 adjusts the left and right distances of each moving end according to the preset reinforcing rib spacing to ensure accurate reinforcing rib spacing. After the spacing is adjusted, the Y-axis linear module 5 and the Z-axis linear module 7 move together to transport the reinforcing rib to the preset welding position of the shelf and put it down; then, the telescopic cylinder 11 is activated to push the welding head 12 at its bottom end down to contact the connection between the reinforcing rib and the shelf, and complete the welding operation; finally, the welded shelf is transported out by the second conveyor roller group 3.

[0029] The variable-pitch module 8 precisely adjusts the spacing of the reinforcing ribs, replacing manual judgment and placement. This avoids spacing errors caused by hand tremors and visual deviations, ensuring uniform stress on the shelves. It prevents shelf deformation due to excessive spacing and material waste due to insufficient spacing, while also ensuring the assembly compatibility of the shelves with the uprights and beams, improving the overall structural stability of the rack. The system realizes the entire process of gripping, adjusting the spacing, placing, and welding the reinforcing ribs without manual operation of each rib, resulting in high efficiency and reducing reliance on skilled workers. Operators only need to add reinforcing ribs at the feeding table 13, avoiding close contact with the welding area and preventing harm from welding sparks and high-temperature radiation, thus improving operational safety. By adjusting the spacing parameters of the variable-pitch module 8 and the travel of the Y-axis / Z-axis linear modules, combined with the clamping component 4, it can adapt to rack shelves of different lengths and with different numbers of reinforcing ribs without replacing core components, reducing equipment replacement costs and expanding the applicability of the device.

[0030] The clamping assembly 4 includes a lifting platform 41, a second mounting plate 42, a servo motor 43, a screw 44, a bearing seat 45, a guide rail 46, a slider 47, a connecting rod 48, a nut 49, a third mounting plate 410, and a clamping plate 411. The top of the lifting platform 41 is fixed with the second mounting plate 42. The top of the second mounting plate 42 is provided with the bearing seat 45, the guide rail 46, and the servo motor 43 from left to right. The left end of the servo motor 43 is connected to the screw 44, and the left end of the screw 44 is inserted into the bearing seat 45. The screw 44 has two threaded sections with opposite thread directions, and each threaded section is screwed with a nut 49. The top of the nut 49 is fixed with the third mounting plate 410, and the top of the third mounting plate 410 is fixed with the clamping plate 411. The top of the guide rail 46 is slidably connected with two sliders 47, and the two sliders 47 are respectively connected to the two nuts 49 through the connecting rod 48.

[0031] Initially, the two clamping plates 411 are open, the lifting platform 41 is in a low position, and the clamping plates 411 are located below the second conveyor roller group 3, without affecting the conveying of the shelf. After the shelf is transported from the first conveyor roller group 1 to the second conveyor roller group, the lifting platform 41 starts and rises, driving the second mounting plate 42 and its upper structure to move upward, so that the clamping plates 411 pass through the gap of the second conveyor roller group 3 until their tops rise above the top of the shelf. The servo motor 43 starts, and its output shaft drives the screw 44 to rotate. Since the screw 44 has two threaded sections with opposite thread directions, and each threaded section is screwed with a nut 49, when the screw 44 rotates, the two nuts 49 will move relative to each other along the screw 44 (moving towards or away from each other simultaneously). During the movement of the nuts 49, they are connected to the slider 47 on the guide rail 46 through the connecting rod 48. The slider 47 slides along the guide rail 46, providing guidance for the movement of the nuts 49 and ensuring that the movement of the two nuts 49 is smooth and synchronous. The third mounting plate 410, which is fixedly connected to the nut 49, moves with the nut 49, thereby driving the top clamping plate 411 to move synchronously, realizing the closing or opening of the two clamping plates 411. When the two clamping plates 411 move towards each other, they gradually approach and clamp the edge of the shelf, firmly fixing the shelf in the center to prevent displacement during welding. After welding is completed, the servo motor 43 reverses, driving the clamping plates 411 to move away from each other to release the shelf. The lifting platform 41 descends, and the clamping plates 411 return to below the second conveying roller group 3, and the shelf is transported out by the second conveying roller group 3.

[0032] The servo motor 43 drives the screw 44 to rotate, and the reverse thread section achieves synchronous movement of the clamping plates 411. Combined with the guiding action of the guide rail 46 and the slider 47, this ensures high moving accuracy and good synchronization of the two clamping plates 411. It can accurately center and stably clamp the shelves, preventing shelf wobbling or shifting during welding, thus providing a fundamental guarantee for precise welding of reinforcing ribs. Furthermore, it can adapt to clamping shelf panels of different lengths without changing clamping components, improving the device's adaptability to different product specifications.

[0033] The inner side of the plywood 411 has a soft pad 412. The soft pad 412 is provided to prevent damage to the shelf panels.

[0034] The device includes several clamping plates 411, which are spaced apart along the length of the third mounting plate 410. The second conveyor roller group 3 includes several rollers 31 spaced back-to-back, with clearance spaces 32 between adjacent rollers 31, through which the clamping plates 411 can pass. The multiple clamping plates 411 clamp the shelf panels, resulting in more stable clamping.

[0035] The top of the feeding platform 13 has a feeding trough 131, the rear end of which has a limiting wall 132, and the front end of the feeding trough 131 penetrates the front side wall of the feeding platform 13. The top of the feeding platform 13 on both the left and right sides of each feeding trough 131 has a clearance groove 133, which communicates with the feeding trough 131. The clearance groove 133 is located in the middle of the feeding trough 131.

[0036] According to production needs, the operator places the cut strip reinforcing ribs one by one into the feeding groove 131 at the top of the feeding platform 13. The width of the feeding groove 131 matches the width of the reinforcing rib, which can limit the reinforcing rib laterally and prevent it from shifting to the left or right. At the same time, the rear end of the reinforcing rib is attached to the limiting wall 132 of the feeding groove 131, which provides longitudinal positioning for the reinforcing rib, ensuring that the rear ends of all reinforcing ribs are aligned and forming a uniform gripping reference. When the finger cylinder 10 moves above the feeding platform 13 to prepare to grip the reinforcing rib, the clearance grooves 133 on the left and right sides of the feeding groove 131 provide clearance space for the grippers of the finger cylinder 10. The two grippers of the finger cylinder 10 can respectively extend into the clearance grooves 133 on both sides and clamp the reinforcing rib from the middle position, avoiding interference between the grippers and the groove wall of the feeding platform 13 and ensuring smooth gripping action. After the finger cylinder 10 clamps the reinforcing rib, it is lifted upward and moved to the welding station; the feeding platform 13 remains in its original position. After the current reinforcing rib is gripped, the operator can continue to add new reinforcing ribs to the feeding trough 131 and enter the next gripping cycle.

[0037] By combining the lateral limiting of the feeding trough 131 with the longitudinal positioning of the limiting wall 132, the reinforcing ribs maintain a uniform posture and position during storage, avoiding skewing or misalignment caused by manual placement. When the finger cylinder 10 grips, it uses the pre-positioned reinforcing rib as a reference, eliminating the need for additional position adjustments and indirectly improving the spacing accuracy of subsequent reinforcing rib welding. The design of the central clearance groove 133 precisely avoids the movement path of the gripper of the finger cylinder 10, allowing the gripper to stably hold the reinforcing rib from the middle, preventing collision damage between the gripper and the feeding table 13, and ensuring that the reinforcing rib is not easily detached during gripping, thus improving the stability of feeding.
