Description

Technical Field

[0001] The invention relates to the technical field of welding anti-deformation, and in particular to an anti-deformation device for producing and processing electronic weighing instruments. Background Art

[0002] Electronic weighing instruments are weighing instruments that use electronic devices to convert the gravity of the weighed object into an electrical signal for measurement. They are mainly composed of weighing sensors, weighing display instruments, scale bodies, connectors, limit devices, power supplies and other components. The scale body is used to carry the weighed object. It is usually formed by welding panels and assembly beams. When welding the panels and assembly beams, one end of the panel heats up rapidly due to the welding heat source, and the temperature is much higher than the front side. Due to the thermal expansion effect, the material on the other side of the welding surface expands more than the welding surface, resulting in partial bulges and deformation of the panel during welding. Panel deformation will have many adverse effects on weighing accuracy, scale service life and appearance. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figures 1 to 10 :

[0032] An anti-deformation device for production and processing of electronic weighing instruments comprises a workbench 1, and a plurality of positioning clamps 11 installed on the workbench 1, a first sliding frame 2 is slidably installed on the workbench 1, a welding robot 21 is arranged on the first sliding frame 2, the first sliding frame 2 drives the welding robot 21 to move along the length direction of the workbench 1 for welding, a plurality of second sliding frames 3 are arranged on both sides of the workbench 1, a lifting platform 31 is installed on the second sliding frame 3, a horizontal platform 32 extending to the top of the workbench 1 is arranged on the lifting platform 31, a plurality of bonding blocks 33 are arranged on the horizontal platform 32, and the bottom of the bonding block 33 is bonded to the panel to be welded of the workbench 1; the bonding block 33 is connected to the panel to be welded by a plurality of vertical second guide rods 331 (such as Figure 7 The laminating wheel 333 is rotatably mounted on the top seat 332, and a pressing block 34 is slidably mounted on the top of the horizontal platform 32. When the pressing block 34 is fitted to the top of the laminating wheel 333, the top seat 332 is pressed to the upper side of the laminating horizontal platform 32. A sealing box 35 is provided on the laminating block 33, and the sealing box 35 is filled with a constant temperature liquid.

[0033] When the anti-deformation device in the present application is used, the staff places the panel to be welded on the workbench 1, and positions and fixes the panel by the positioning clamp 11 to ensure that the panel is accurately positioned during the welding process. At the same time, according to the size and shape of the panel, the position of the second sliding frame 3 on both sides of the workbench 1 is adjusted so that the horizontal platform 32 on the lifting platform 31 is located in a suitable position, so that the bonding block 33 can contact the panel to be welded on the workbench 1 in a natural state, and the bonding block 33 is inserted on the horizontal platform 32 through the second guide rod 331 and is in a movable state. The first sliding frame 2 drives the welding robot 21 to move along the length direction of the workbench 1 to weld the panel and the assembly beam. During the welding process, due to the effect of the welding heat source, one end of the panel heats up rapidly, which may cause local protrusions and deformation. At this time, the bonding block 33 is tightly attached to the panel, which can apply a certain pressure to the panel and limit the deformation of the panel caused by thermal expansion. The constant temperature liquid filled in the closed box 35 can maintain a certain temperature, which helps to stabilize the temperature of the panel, reduce the generation of thermal stress, and further prevent the deformation of the panel. Even if a certain part of the panel is deformed, the bonding workbench 1 at that position will be deformed and tilted upward, lifting the bonding block 33 at the corresponding position. At this time, the bonding block 33 moves upward, driving the top seat 332 and the bonding wheel 333 to move upward. The pressing block 34 can be translated to the top of the bonding wheel 333, pressing the top seat 332 to the upper side of the bonding platform 32 to reset the bonding block 33, thereby pressing and straightening the deformed part of the panel to ensure the stability of the panel's morphological structure.

[0034] In order to ensure that the pressing block 34 can press all the bonding blocks 33 on a horizontal platform 32, the following features are specifically set:

[0035] The horizontal platform 32 extends along the width direction of the workbench 1, and is provided with a plurality of mounting seats 321 distributed at equal intervals along the length direction of the horizontal platform 32. The mounting seats 321 are provided with guide holes 322 (such as Fig.10 As shown), the second guide rod 331 is inserted into the corresponding guide hole 322; a second slide rail 323 extending along the length direction of the horizontal platform 32 is provided on the top of the horizontal platform 32, and the pressing block 34 is slidably installed in the second slide rail 323.

[0036] In this embodiment, the mounting seats 321 and guide holes 322 are evenly spaced along the length direction of the horizontal table 32, which can accurately position each bonding block 33. The pressing block 34 moves along the arrangement direction of the bonding blocks 33 with the help of the second slide rail 323, so that all the bonding blocks 33 can be pressed one by one, ensuring that the entire welding area can obtain stable and uniform pressure, so that the deformation of various parts of the panel during welding can be effectively suppressed, thereby improving the anti-deformation effect.

[0037] In order to ensure that the pressing block 34 can press down the laminating wheel 333 raised to any position when translating, the following features are specifically provided:

[0038] The pressing block 34 is provided with an inclined surface 341 at one end facing the center of the workbench 1. Figure 7 As shown in the figure, the pressing block 34 extends obliquely from the bottom of the pressing block 34 toward the center of the workbench 1.

[0039] In this embodiment, when the bonding block 33 needs to be pressed to better fix the panel to be welded, the pressing block 34 slides in the second slide rail 323 along the length direction of the horizontal table 32. As the pressing block 34 slides, its inclined surface 341 gradually approaches and contacts the bonding wheel 333. Since the inclined surface 341 extends obliquely from the bottom of the pressing block 34 toward the center of the workbench 1, the bonding wheel 333 will roll downward along the inclined surface 341 after contacting the inclined surface 341, and at the same time push the top seat 332 to move downward, thereby driving the bonding block 33 to move downward, so that the bonding block 33 fits the panel to be welded more closely. In this embodiment, a slope 341 is provided at one end of the pressing block 34. No matter to which position the bonding wheel 333 is raised following the upward movement of the bonding block 33, the slope 341 can contact the bonding wheel 333 and press it downward, thereby ensuring that the pressing block 34 can effectively press all the bonding blocks 33 on a horizontal platform 32, ensuring that the part of the panel to be welded under the horizontal platform 32 can be fixed evenly and tightly, and kept straight, to avoid deformation of the panel during welding due to the part not being pressed.

[0040] In order to achieve the purpose of enabling the pressing block 34 to move horizontally along the second slide rail 323, the following features are specifically provided:

[0041] Press block 34 (such as Figure 8 An extension plate 342 is provided at one end away from the inclined surface 341, and the extension plate 342 is fixedly connected to the working end of a linear driver 343 fixedly installed on the outer side of the horizontal platform 32. The working end of the linear driver 343 moves horizontally along the length direction of the horizontal platform 32.

[0042] In this embodiment, when the laminating block 33 needs to be pressed and fixed, the linear driver 343 is started, and its working end moves horizontally along the length direction of the horizontal table 32, pushing the extension plate 342, thereby driving the pressing block 34 to slide in the second slide rail 323. The linear driver 343 can be a cylinder, an oil cylinder or an electric push rod.

[0043] In order to automatically start the linear drive 343 on the second sliding frame 3 to which a bonding block 33 belongs when the bonding block 33 is lifted by the deformed panel, so that the pressing block 34 moves to press and reset the bonding block 33, the following features are specifically set:

[0044] The bottom of the pressing block 34 is provided with a slot 344 extending along the length direction of the pressing block 34, and the pressing block 34 is provided with a sensing unit 345 at one end of the slot 344 away from the inclined surface 341. The working end of the sensing unit 345 is horizontally arranged and is flush with the top of the bonding wheel 333 when the top seat 332 is bonded to the upper side of the horizontal platform 32; the sensing unit 345 is connected to the linear driver 343 through the controller signal.

[0045] In this embodiment, before the welding work begins, the second guide rod 331 of the bonding block 33 is inserted into the guide hole 322 of the horizontal table 32, the bonding block 33 is bonded to the upper side of the panel, the bonding wheels 333 are at the same height, and the pressing block 34 is in the initial position in the second slide rail 323 and is not in contact with the bonding wheel 333. The working end of the sensing unit 345 in the slot 344 at the bottom of the pressing block 34 is flush with the top of the bonding wheel 333. At this time, the sensing units 345 on both sides of the workbench 1 are aligned. The sensing unit 345 can be a laser sensor, etc. When the two sensing units 345 are aligned and the signal is not blocked, the sensing unit 345 does not trigger the signal, and the linear drive 343 is in a stationary state. During the welding process, if the panel undergoes local convex deformation due to thermal expansion, the bonding block 33 bonded thereto will be lifted upward, and the bonding block 33 drives the top seat 332 and the bonding wheel 333 to rise together through the second guide rod 331. When the bonding wheel 333 rises above a certain height, that is, higher than the working end of the sensing unit 345, the sensing unit 345 detects this change and transmits a signal to the controller. After receiving the signal from the sensing unit 345, the controller issues a command to start the linear driver 343, and the working end of the linear driver 343 moves horizontally along the length direction of the horizontal table 32, pushing the pressing block 34 to move toward one end of the inclined surface 341 in the second slide rail 323. During the movement of the pressing block 34, its inclined surface 341 gradually contacts the bonding wheel 333 and presses downward, so that the bonding wheel 333, the top seat 332 and the bonding block 33 are gradually reset until the top seat 332 is again bonded to the upper side of the horizontal table 32. At this time, the sensing units 345 located on both sides of the workbench 1 can detect each other again, the signal can be stopped, the linear driver 343 stops working, and the pressing block 34 stops moving, completing a pressing and resetting process of the bonding block 33 raised due to panel deformation. This embodiment can monitor the position change of the bonding block 33 in real time. When the panel is deformed and the bonding block 33 is lifted, the linear drive 343 and the pressing block 34 are automatically started to press and reset without human intervention, ensuring that the pressure on the panel is always effective, correcting the deformation trend of the panel in time, and ensuring the flatness of the panel during the welding process. There is no need for humans to pay attention to the deformation of the panel and make manual adjustments at all times.

[0046] In order to adjust the initial position of the bonding block 33 according to panels of different thicknesses, so that it can fully bond to the panel surface before welding begins and keep the bonding wheel 333 at the top at the same height, the following features are specifically set:

[0047] A limiting sleeve 311 (such as Figure 6 As shown), and a plurality of vertically extending first guide rods 312 (as shown Fig.10 As shown), the first guide rod 312 is inserted into the second sliding frame 3, and the second sliding frame 3 is provided with a threaded hole 36 which is in the same straight line as the limiting sleeve 311. An adjusting screw 361 is spirally installed in the threaded hole 36, and the top limit of the adjusting screw 361 is installed in the limiting sleeve 311.

[0048] In this embodiment, the staff can adjust the height position of the lifting platform 31 by rotating the adjusting screw 361. Since the adjusting screw 361 is screw-matched with the threaded hole 36 on the second sliding frame 3, and the top limit of the adjusting screw 361 is installed in the limit sleeve 311 at the bottom of the lifting platform 31, as the adjusting screw 361 rotates, it will move up and down in the threaded hole 36 and raise or lower the lifting platform 31 accordingly, so that the initial position of the bonding block 33 can be adjusted according to panels of different thicknesses, so that it can be fully bonded to the panel surface before welding begins and keep the bonding wheel 333 at the top at the same height. In this embodiment, the height of the bonding block 33 can be adjusted by simply rotating the adjusting screw 361. The operation process is convenient and quick, and does not require complicated operation procedures and professional skills, which reduces the difficulty and labor intensity of the operator's work and improves work efficiency.

[0049] In order to realize the purpose that when the first sliding frame 2 drives the welding robot 21 to move to the next position of the panel and the assembly beam for welding, the second sliding frame 3 can move to both sides of the workbench 1 to release the welding position, the following features are specifically set:

[0050] The bottom of the second sliding frame 3 is provided with a rack 37 extending horizontally toward the center of the workbench 1. A plurality of central gears 12 are rotatably mounted at the bottom of the workbench 1. The axis of the central gear 12 is vertically arranged (e.g. Figure 4 As shown), the racks 37 of the two second sliding frames 3 located on both sides of the workbench 1 are respectively located on both sides of the central gear 12 and meshed with the central gear 12; a rotation driver 121 for driving the central gear 12 to rotate around its own axis is fixedly installed on one side of each central gear 12.

[0051] The welding robot 21 in this embodiment is driven by the first sliding frame 2 to weld the panel and the assembly beam along the length direction of the workbench 1. When a welding position is completed and needs to be moved to the next position to continue welding, the rotary driver 121 is started to drive the central gear 12 connected thereto to rotate around its own vertical axis. Since the racks 37 of the two second sliding frames 3 located on both sides of the workbench 1 are respectively located on both sides of the central gear 12 and meshed with it, the rotation of the central gear 12 will drive the racks 37 on both sides to move toward or away from each other, thereby driving the second sliding frames 3 to move to both sides of the workbench 1. In this process, the horizontal table 32 and the bonding block 33 gradually move away from the welding position, releasing the space above to avoid interference with the subsequent welding operation of the welding robot 21. The rotary driver 121 can be a servo motor.

[0052] In order to guide the movement of the second sliding frame 3, the following features are specifically provided:

[0053] A plurality of guide sleeves 13 are arranged on both sides of the workbench 1 , and the guide sleeves 13 are sleeved on the outside of the rack 37 .

[0054] In this embodiment, the rack 37 on the second sliding frame 3 is slidably installed in the guide sleeve 13, so as to ensure the stability of the meshing connection state between the rack 37 and the central gear 12, and also guide the moving direction of the second sliding frame 3.

[0055] In order to achieve the purpose of maintaining the constant temperature liquid in the closed box 35 at the same temperature, the following features are specifically provided:

[0056] The two adjacent closed boxes 35 on each second sliding frame 3 are connected via a water inlet pipe 351 and a water outlet pipe 352 (such as Figure 3 As shown), the water inlet pipe 351 on the closed box 35 near one end of the lifting platform 31 is connected to the output end of the constant temperature liquid delivery device, and the water outlet pipe 352 on the closed box 35 near one end of the lifting platform 31 is connected to the input end of the constant temperature liquid recovery device.

[0057] In this embodiment, after the welding work starts, the constant temperature liquid delivery device is started, and the constant temperature liquid of the set temperature is delivered to the closed box 35 near one end of the lifting platform 31 through the water inlet pipe 351. The constant temperature liquid entering the closed box 35 flows in each closed box 35 in turn through the water inlet pipe 351 and the water outlet pipe 352 between adjacent closed boxes 35, realizing heat exchange, so that the temperature of the constant temperature liquid in each closed box 35 tends to be consistent. The constant temperature liquid that has circulated through all the closed boxes 35 flows out from the water outlet pipe 352 on the closed box 35 near one end of the lifting platform 31 and is delivered to the constant temperature liquid recovery device. The constant temperature liquid recovery device detects and adjusts the temperature of the recovered constant temperature liquid, and after it reaches the set temperature, it is delivered to the closed box 35 again through the constant temperature liquid delivery device, and this cycle is repeated to keep the constant temperature liquid in the closed box 35 always at the same temperature. This embodiment ensures that the temperature of the constant temperature liquid in each closed box 35 is consistent, so that the temperature of the parts in contact with the constant temperature liquid such as the bonding block 33 is uniform. When the panel is subjected to anti-deformation treatment, a stable and uniform temperature environment can be provided, effectively avoiding uneven local deformation of the panel caused by temperature differences.

[0058] In order to ensure that the second sliding frame 3 does not affect the movement of the first sliding frame 2, the following features are specifically set:

[0059] The workbench 1 is provided with first slide rails 14 (such as Figure 2 As shown), the first slide rail 14 extends along the length direction of the workbench 1, and both ends of the first sliding frame 2 are slidably installed on the first slide rail 14; a sinking beam 15 is provided at the bottom of the workbench 1, and the guide sleeve 13 is provided at the bottom of the sinking beam 15.

[0060] The first slide rail 14 in this embodiment provides an exclusive moving track for the first sliding frame 2, clarifies its moving path, and cooperates with the reasonable layout of the sinking beam 15 at the bottom of the workbench 1 and the guide sleeve 13 for related components to prevent the occurrence of physical interference such as collision and friction between the second sliding frame 3 and the first sliding frame 2, thereby ensuring that the welding action of the welding robot 21 is not hindered and maintaining stable welding efficiency.

[0061] Working principle: When in use, the staff places the panel to be welded on the workbench 1, and uses the positioning clamp 11 to position and fix the panel to ensure that the panel is accurately positioned during the welding process. At the same time, according to the size and shape of the panel, adjust the position of the second sliding frame 3 on both sides of the workbench 1 so that the horizontal platform 32 on the lifting platform 31 is located in a suitable position, so that the bonding block 33 can contact the panel to be welded on the workbench 1 in a natural state. The first sliding frame 2 drives the welding robot 21 to move along the length direction of the workbench 1 to weld the panel and the assembly beam. During the welding process, due to the action of the welding heat source, one end of the panel heats up rapidly, which may cause local protrusions and deformation. At this time, the bonding block 33 fits tightly on the panel and can exert a certain pressure on the panel to limit the deformation of the panel due to thermal expansion. The constant temperature liquid filled in the pressing block 34 can maintain a certain temperature and reduce the generation of thermal stress. When a certain part of the panel is deformed, the bonding workbench 1 at that position will be deformed and tilted upward, lifting the bonding block 33 at the corresponding position. At this time, the bonding block 33 moves upward to drive the top seat 332 and the bonding wheel 333 to move upward. The pressing block 34 can be translated to the top of the bonding wheel 333, pressing the top seat 332 to the upper side of the bonding platform 32 to achieve the reset of the bonding block 33, thereby pressing and straightening the deformed part of the panel.

[0062] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
