Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, specifically a computer testing instrument processing equipment. Background Technology

[0002] Computer testing refers to the process of collecting analog quantities such as temperature, pressure, flow rate, and displacement, converting them into digital quantities, and then storing, processing, displaying, or printing them by a computer. Its main function is to convert analog signals into digital signals and send the conversion results into the computer memory through a communication port. Computer testing systems mainly consist of sensors, signal conditioners, computers, and application software. Therefore, computer testing systems have a higher degree of integration, are easier to maintain and expand, and are also easier to carry out on-site work. During the manufacturing process, the brackets of most computer testing instruments need to be assembled by welding.

[0003] Before welding computer testing instrument brackets, it is necessary to ensure that the surface of the components to be welded is flat and clean. If the surface of the computer testing instrument bracket contains impurities such as dust, rust, and oil, it will cause the weld points to crack, blister, or even fall off. If the welding surface of the computer testing instrument components is uneven during welding, the welding surfaces will not be able to achieve seamless bonding, thereby reducing the welding quality and strength of the weld points. Most traditional seamless welding devices do not have cleaning components and cannot guarantee the flatness and cleanliness of the welding surface of the computer testing instrument during welding, thus failing to guarantee the welding quality. Summary of the Invention

A moving sleeve is threaded onto the lead screw inside the third rail, and the top end of the moving sleeve is fixed to the bottom end of the welding robotic arm.

[0008] Furthermore, auxiliary rollers are fixed at the bottom ends of the two moving rails on both sides of the first moving rail, and the auxiliary rollers are rotatably connected to the top of the support base. The two support rods are both set as inverted "L" shapes. The opposite sides of each set of two fixed clamping blocks are set as recesses to cooperate with the computer testing instrument bracket. The center lines between the first moving rail, the second moving rail, and the two fixed clamping blocks are all located on the same vertical plane. The center line of the pretreatment component and the welding robot arm are located on the same vertical plane, and the two vertical planes are perpendicular to each other.

[0009] Furthermore, each of the moving sleeves has a thread inside that mates with the lead screw, the threads inside the moving sleeves of moving rail one and moving rail two are in opposite directions, and the moving rail one, moving rail two and moving rail three all have a sliding groove inside that mates with the moving sleeve, and the four servo motors are respectively fixedly installed on moving rail one, moving rail two and moving rail three.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, a combined pretreatment structure is used, with a motor driving multiple cleaning components to perform coarse grinding, fine grinding, and wiping combined treatments on the welding surface of the computer testing instrument. This avoids unevenness or impurities on the welding surface. Furthermore, during welding, the cleaning components can be moved to the side without manual control. This solves the problem that existing computer testing instrument processing equipment often results in low-quality, weak welding points due to unevenness or dirt on the welding surface, or even the inability to achieve seamless welding. This improves the welding effect of the welding device.

[0017] 2. In this invention, the combined design of moving rail one, moving rail two, and moving rail three allows for adjustment based on the length of the computer testing instrument bracket or the size of the welding surface. Furthermore, the transmission design between moving rail two and the connecting rod enables the two moving rail two to move relative to each other after pretreatment, pushing the cleaning component to the side to align and fit the pretreated welding surface. This allows the welding robotic arm to be driven by moving rail three for welding, thus improving the practicality of the welding device.

[0018] 3. In this invention, the detachable design between the fixing clamp and the connecting plate allows for the selection of the appropriate fixing clamp based on the shape or thickness of the computer testing instrument bracket during welding. This ensures that the side of the fixing clamp is fully in contact with the computer testing instrument bracket to be welded when clamped, thereby guaranteeing the stability of the bracket during welding. This ensures that the welding surface of the computer testing instrument bracket remains aligned and in contact during welding, preventing misalignment of the welding surface due to unstable bracket clamping, and further improving the welding effect of the welding device.

[0031] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Reference Figures 1 to 6 A computer testing instrument processing device includes a support base 1 and a welding robotic arm 8. A first moving rail 2 is fixed on the support base 1, and a second moving rail 3 is symmetrically arranged on the first moving rail 2. A third moving rail 4 is fixed at the top of the middle side of the support base 1. The bottom end of the welding robotic arm 8 is connected to the third moving rail 4 through a drive assembly. The two second moving rails 3 are connected to the first moving rail 2 through a drive assembly. Each second moving rail 3 is connected to a support rod 10 through a drive assembly, and the top end of the support rod 10 is connected to a fixing clamp 11 through a fixing assembly. A pre-processing assembly is arranged between the two second moving rails 3.

[0033] Specifically, auxiliary rollers 9 are fixed at the bottom of the two moving rails 3 on both sides of the moving rail 1 2, and the auxiliary rollers 9 are rolledly connected to the top of the support base 1. The auxiliary rollers 9 support the moving rail 2 3, making the moving rail 2 3 more stable and less strenuous when moving. The two support rods 10 are both set as inverted "L" shapes. The center lines between the moving rail 1 2, the moving rail 2 3 and the two fixed clamping blocks 11 are all located on the same vertical plane. The center line of the pretreatment component and the welding robot arm 8 are located on the same vertical plane. The two vertical planes are perpendicular to each other, ensuring that the welding robot arm 8 can weld the welding surface after moving during welding, and ensuring that the welding surfaces of the computer testing instrument bracket can be aligned when the two moving rails 2 3 move relative to each other.

[0034] As an optimization solution, such as Figure 5 and Figure 6 As shown, the pretreatment assembly includes a motor 19, a support turntable 21, an outer support plate 22, and a cleaning component 24. A moving rail 3 4 is fixed to the top of the support base 1 on the opposite side of the welding robotic arm 8. A limiting roller 15 is slidably sleeved inside the limiting rail 14. A fixing rod 17 is symmetrically fixed to the top of the limiting roller 15. Connecting rods 16 are rotatably connected to both sides of one end of the limiting roller 15 extending outside the limiting rail 14. The other ends of the two connecting rods 16 are rotatably connected to the moving rail 2 3. The tops of the two fixing rods 17 are fixed to the support plate 18, and a support turntable 21 is provided on both sides of the support plate 18. A... A motor 19 is provided on one side, and the output end of the motor 19 is fixed on a rotating rod 20 on one side. The rotating rods 20 on both sides are rotatably connected to the support plate 18 through bearings. The ends of the rotating rods 20 on both sides away from the motor 19 are fixed on the support turntable 21. Several outer support plates 22 are fixed at equal intervals along the outer edge of the support turntable 21. There are four sets of outer support plates 22 on the outer side of each support turntable 21. Each fixed plate 23 is fixed to the rotating rod 25 by bolts, which makes it easy to disassemble the fixed plate 23 and thus easy to replace the cleaning part 24.

[0035] Each outer support plate 22 has a rotating rod 25 rotatably fitted inside. A fixing plate 23 is fixed to the side of each rotating rod 25 closest to the moving rail 23. A cleaning component 24 is fixed to the side of the fixing plate 23 furthest from the supporting turntable 21. The cleaning components 24, arranged clockwise, consist of a coarse grinding roller, a fine grinding roller, a wet wiping cotton roller, and a dry wiping cotton roller. The cleaning components 24 process the surfaces to be welded one by one, grinding them smooth and cleaning them. The output end of the motor 22 is fixed to the rotating rod 25 corresponding to the coarse grinding roller cleaning component 24. A partition plate is rotatably connected to the output end of the motor 22 via a bearing. The two rotating rods are fixed to the outer support plate 22 on the side. Each rotating rod 25 is fixed with a driven wheel 26 on the side near the rotating rod 1 20. The driven wheels 26 on each side are connected by a transmission belt 27. The two rotating rods 25 on both sides are fixedly connected by a linkage rod 2 31. Each rotating rod 1 20 on each side is fixed with a bevel gear 1 28. The bevel gear 1 28 is meshed with a bevel gear 29 on the side. The two bevel gears 29 on both sides are fixedly connected by a linkage rod 30. The outer sides of the two bevel gears 29 are rotatably connected to the support plate 18 through bearings. One rotating rod 25 is fixedly connected to the output end of the motor 2 32.

[0036] Specifically, the limiting rail 14 has a convex groove inside that mates with the limiting roller 15. The top of the limiting rail 14 is flush with the top of the moving rail 1 2. The bottom of the limiting roller 15 is rolledly connected to the bottom of the groove inside the limiting rail 14. The other end of each connecting rod 16 is located on the side of the moving rail 2 3 away from the limiting rail 14. Each connecting rod 16 is located above the moving rail 2, ensuring that the limiting roller 15 can move stably inside the limiting rail 14 while preventing the limiting roller 15 from separating from the limiting rail 14. This also makes it easier for the limiting roller 15 to move. The support plate 18 is U-shaped. The two rotating rods 20 are rotatably connected to both sides of the support plate 18 through bearings, which facilitates the support plate 18 to support the rotating rods 20 and the motor 19. Each driven wheel 26 is hollow in the shape of an "I" shape. The transmission belt 27 on each side is rectangular and mates with the four driven wheels 26, which facilitates the transmission belt 27 to drive the driven wheels 26 to rotate.

[0037] As a further optimization scheme, such as Figure 4As shown, the drive assembly includes a lead screw 5, a moving sleeve 6, and a servo motor 7. Lead screw 5 is rotatably connected to the interior of moving rails 1, 2, 3, and 3 4 via bearings. One end of the lead screw 5 extending to the outside of moving rails 1, 2, 3, or 3 4 is fixed to the output end of the servo motor 7. Moving sleeves 6 are symmetrically threaded onto the lead screw 5 inside moving rails 1 and 2, 3. The top of the moving sleeve 6 inside moving rail 1 is fixed to the bottom of moving rail 2, 3, and 3, respectively, and the top of the moving sleeve 6 inside moving rail 2 is fixed to the bottom of the support rod 10. Moving sleeves 6 are threaded onto the lead screw 5 inside moving rail 3 4, and the top of the moving sleeve 6 is fixed to the bottom of the welding robotic arm 8. The movable design of moving rails 2, 3, the welding robotic arm 8, and the fixed clamp 11 facilitates the raising and lowering and fixing of the computer testing instrument support, improving the applicability of the welding device and the stability during welding.

[0038] Specifically, the movable sleeve 6 has a thread inside that mates with the lead screw 5. The threads inside the two movable sleeves 6, movable rail 1 2 and movable rail 2 3, are in opposite directions. Movable rail 1 2, movable rail 2 3 and movable rail 3 4 all have sliding grooves inside that mate with the movable sleeve 6. Four servo motors 7 are fixedly installed on movable rail 1 2, movable rail 2 3 and movable rail 3 4 respectively. When the servo motors 7 on movable rail 1 2 and movable rail 2 3 are running, they can drive the two movable sleeves 6 to move relative to each other or in opposite directions. This can drive the two movable rails 2 3 to move relative to each other so that the welding surfaces fit together, or the fixed clamping block 11 can move relative to each other to clamp the computer testing instrument bracket.

[0039] As a further optimization scheme, such as Figure 7 As shown, the fixing assembly includes a connecting plate 12 and a fixing screw 13. Each support rod 10 is fixed to one end of the fixing clamp 11 near the fixing block 11. Each fixing clamp 11 is symmetrically fixed to one side of the connecting plate 12. Each fixing screw 13 is threaded with a nut at one end extending to the outside of the connecting plate 12. Each connecting plate 12 has symmetrical fixing holes that mate with the fixing screw 13. Each pair of fixing clamps 11 has a recess on opposite sides to mate with the computer testing instrument bracket. Through the detachable design of the fixing clamps 11, the fixing clamps 11 with corresponding matching grooves can be selected according to the shape of the computer testing instrument bracket, thereby ensuring the firmness of the fixing clamps 11 during clamping and thus ensuring the stability of the computer testing instrument bracket during welding.

[0040] Working principle: When welding the computer test instrument bracket, first select the corresponding fixing block 11 according to the shape of the computer test instrument bracket. Pass the fixing screw 13 of the fixing block 11 through the connecting plate 12 and fix it with a nut. Then place the computer test instrument bracket component with welding between the two fixing blocks 11. Turn on the servo motor 7 on the second moving rail 3, causing the servo motor 7 to drive the lead screw 5 to rotate. This will cause the two moving sleeves 6 inside the second moving rail 3 to move relative to each other, thereby causing the fixing blocks 11 on both sides to move relative to each other and clamp the computer test instrument bracket, thus fixing the computer test instrument bracket. During fixing, the welding end of the computer test instrument bracket should be placed against the connecting plate 12. Clean one side of part 24, then turn on motor 2 32, causing motor 2 32 to run and drive its fixed rotating rod 25 to rotate. The rotation of rotating rod 25 drives the outer fixed driven wheel 26 to rotate, which in turn drives the other driven wheels 26 on the same side to rotate via transmission belt 27, thereby driving the other rotating rods 25 on the same side to rotate. When rotating rod 25 rotates, it drives the rotating rod 25 on the other side to rotate via linkage rod 2 31, thus driving all rotating rods 25 on the other side to rotate via driven wheels 26 and transmission belt 27. When the rotating rods 25 on both sides rotate, they drive all the cleaning parts 24 on both sides to rotate, pre-treating the surface to be welded. After one cleaning part 24 is processed, turn on motor 1 19. This causes motor 19 to run, driving rotating rod 20 to rotate. When rotating rod 20 rotates, it drives another support turntable 21 to rotate via bevel gear 28, bevel gear 29, and linkage rod 30. The two support turntables 21 rotate clockwise, aligning another cleaning component 24 with the surface to be welded. The cleaning component 24 then continues to process the surface to be welded. After the cleaning component 24 has finished processing and the surface to be welded is clean and tidy, the servo motor 7 at the upper end of moving rail 2 is activated. This servo motor 7 drives the internal lead screw 5 of moving rail 2 to rotate, which in turn drives the two moving rails 2 3 to move relative to each other via two moving sleeves 6. During movement, the connecting rod 16 pushes the limiting roller 15, causing the limiting roller... Move wheel 15 outward to move cleaning part 24 to be aligned with the welding surface. Turn on servo motor 7 on moving rail 3 4 to rotate lead screw 5 inside it. This will move welding robotic arm 8 via moving sleeve block 6. After welding robotic arm 8 moves close to the computer test instrument bracket, turn on welding robotic arm 8 to weld the connection of the computer test instrument bracket. After welding is completed, servo motor 7 will move welding robotic arm 8 away from the computer test instrument bracket. Then turn on servo motor 7 on moving rail 2 3 to release the clamping blocks 11 on both sides from the computer test instrument bracket. Then remove the computer test instrument bracket.
