Description

Technical Field

[0001] This utility model relates to the field of vertical line suspended platform manufacturing and testing in the FCBGA industry, specifically to a fixing device for suspended platform welding. Background Technology

[0002] With the rapid development of semiconductor automation, substrate production lines are mostly automated. As one type of automated production line, the suspended platform includes the main body of the suspended platform and the cover plate fixing frame and cover plate set on the main body of the suspended platform. The cover plate fixing frame is used to fix the cover plate, and the cover plate is used to fix the substrate. When the suspended platform is working, the substrate is first placed in the suspended platform, and then the cover plate is automatically placed by the robot arm. Since no human intervention is required in the suspended platform production line, if the position of the cover plate fixing frame is not accurate, the position of the robot arm to place the cover plate will be inaccurate, and thus the cover plate cannot be placed correctly. Therefore, the dimensional accuracy requirements of each component of the suspended platform are more stringent.

[0003] Suspended platforms are generally formed by welding steel pipes and fixed plates. However, during the welding process, external factors can easily lead to instability and weld deviation, which reduces the welding accuracy of the suspended platform. In subsequent automated operations, this can result in inaccurate installation of the platform's cover plate, affecting the products produced and reducing the product qualification rate and production efficiency. Utility Model Content

[0004] In order to overcome the defects in the prior art, this utility model provides a fixing device for welding suspended platforms. By correcting and fixing the parts of the suspended platform with different precision requirements, the welding efficiency and dimensional accuracy of the suspended platform can be improved.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a fixing device for welding suspended platforms, comprising:

[0007] A fixing frame, wherein a fixing plate is provided on the fixing frame, and a fixing slot is provided in the fixing plate for the basket to be welded to pass through;

[0008] And the following are provided on the fixed plate:

[0009] The first positioning element, having at least two elements, is disposed on both sides of the fixed groove along the transverse direction of the fixed groove.

[0010] The second positioning element includes at least one fixing element and at least one movable element, wherein the at least one fixing element and at least one movable element are respectively arranged diagonally opposite each other in the fixing slot;

[0011] The third positioning element, having at least two, is disposed on both sides of the fixed groove along the longitudinal direction of the fixed groove.

[0012] The positioning pins are arranged on both longitudinal sides of the fixed slot and are rotatably connected to the fixed plate. The rotation direction of the positioning pins is approximately perpendicular to the plane of the fixed slot.

[0013] The above technical solution uses a first positioning component to fix both sides of the basket to be welded along its width direction, a second positioning component to fix the diagonals of the basket to be welded, and a third positioning component and positioning pins to fix the cover plate fixing frame of the basket to be welded. Thus, according to different welding precision requirements, different parts of the basket to be welded are corrected and fixed separately using different positioning components, so as to achieve stable welding of the basket and improve the welding efficiency and dimensional accuracy of the basket.

[0014] Furthermore, the fixing frame also includes a base frame and side frames connecting the fixing plate and the base frame. The base frame is formed by a first crossbar arranged along the length direction and a second crossbar arranged along the width direction, and the side frames are formed by a plurality of support rods arranged vertically. The structural design of the fixing frame enables it to remain stable, thereby maintaining stability during the fixing of the suspended platform and welding process, further improving the welding efficiency and dimensional accuracy of the suspended platform.

[0015] Furthermore, a base plate is provided on the base frame, a driving component is provided on the base plate, and a tray is provided on the driving component. The driving component is located at the bottom of the fixing frame and is used to adjust the height of the basket to be welded, so that the basket to be welded reaches the fixing and welding height of the fixing plate.

[0016] Furthermore, the first positioning member includes a first driving member and a first fixing block connected to the first driving member. The first driving member drives the first fixing block to move to contact the basket to be welded, so that the first fixing block is firmly pressed against both sides of the basket to be welded to form a fixation.

[0017] Furthermore, the movable component includes a second driving component and a second fixing block connected to the second driving component. The second driving component drives the second fixing block to move to contact the basket to be welded, so that the second fixing block is firmly pressed against the basket to be welded to form a fixation.

[0018] Furthermore, the second positioning component includes two movable parts, one of which is oriented perpendicular to the longitudinal direction of the fixing slot, and the other is oriented at an angle of 40° to 50° to the longitudinal direction of the fixing slot. The obliquely oriented movable parts can fix the diagonal of the basket to be welded, improving the stability of the fixation and ensuring that the welding error is controlled within 1mm.

[0019] Furthermore, the third positioning component includes a third driving component and a third fixing block connected to the third driving component. The third driving component drives the third fixing block to move to contact the basket to be welded, so that the third fixing block is firmly pressed against the cover plate fixing frame of the basket to be welded to form a fixation.

[0020] Furthermore, a slot is formed on the third fixing block extending from one end toward the fixing groove to the other end away from the fixing groove. The slot can hold the cover plate fixing frame of the basket to be welded, thereby correcting and fixing the position of the cover plate fixing frame.

[0021] Furthermore, the third fixing block has stops on both sides, and the stops are in contact with the third fixing block. The stops are used to restrict the movement direction of the third fixing block and prevent the third fixing block from deviating during movement.

[0022] Furthermore, the positioning pin includes a positioning rod connected to the fixing plate and a positioning plate connected to the positioning rod. Both the first end of the positioning plate and the positioning rod have through holes. The positioning plate is connected to the positioning rod by bolts passing through the through holes. The second end of the positioning plate has a protrusion. The positioning plate can be pulled up or down. When fixed, the protrusion on the positioning plate inserts into a groove on the fixing frame of the suspended basket cover to be welded, thereby correcting and fixing the position of the groove on the fixing frame.

[0023] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0024] This application uses a first positioning component to fix both sides of the basket to be welded along its width direction, a second positioning component to fix the opposite corners of the basket to be welded, and a third positioning component and a positioning pin to fix the cover plate fixing frame of the basket to be welded. Thus, according to different welding precision requirements, different parts of the basket to be welded are corrected and fixed separately using different positioning components, so as to achieve stable welding of the basket and improve the welding efficiency and dimensional accuracy of the basket.

[0035] Reference Figures 1-3 As shown, this application embodiment provides a fixing device for welding suspended platforms, including: a fixing frame 1, which is used to place and fix the suspended platform to be welded; a fixing plate 2 is provided on the fixing frame 1; and a fixing slot 3 is provided in the fixing plate 2 for the suspended platform to be welded to pass through. In use, the suspended platform to be welded is placed in the fixing frame 1 through the fixing slot 3. The fixing plate 2 is provided with a first positioning member, a second positioning member, a third positioning member, and a positioning pin. There are at least two first positioning members, which are arranged laterally on both sides of the fixing slot 3. The second positioning member includes at least one fixing member 8 and at least one movable member. At least one movable component is respectively arranged diagonally opposite each other in the fixed slot 3. There are at least two third positioning components, which are arranged longitudinally along both sides of the fixed slot 3. Positioning pins are arranged longitudinally on both sides of the fixed slot 3, and are rotatably connected to the fixed plate 2. The rotation direction is approximately perpendicular to the plane of the fixed slot 3. Thus, by using the first, second, third, and positioning components and positioning pins arranged at different positions in the fixed slot 3, the parts of the welding basket with different welding precision requirements are respectively corrected and fixed, thereby improving the welding efficiency, welding precision, and dimensional accuracy of the welding basket. The lateral direction of the fixed slot 3 is the width direction, and the longitudinal direction of the fixed slot 3 is the length direction.

[0036] like Figure 4As shown in the figure, this application embodiment provides a structural schematic diagram of a suspended platform. The suspended platform includes a main body and a cover plate fixing frame 18 disposed on the main body. The main body has a rectangular cross-section. The cover plate fixing frame 18 is used to fix the cover plate 19. The cover plate fixing frame 18 is provided with a groove. During welding, the suspended platform is first rough welded (spot welded) to form a frame. Then, the suspended platform is placed in the fixing frame 1 through the fixing slot 3, so that the side of the suspended platform to be welded with the cover plate fixing frame 18 is opposite to the third positioning member and the positioning pin. The first positioning member is used to correct and fix the two sides of the suspended platform along its width direction. The second positioning member is used to correct and fix the two sides of the suspended platform along its length direction. After the cover plate fixing frame 14 is corrected and fixed by the third positioning member and the positioning pin, the suspended platform is then fine welded (full welded). This improves the welding efficiency and dimensional accuracy of the suspended platform, thereby avoiding the impact on the accuracy of the cover plate placement during automated operation.

[0037] Specifically, such as Figures 1-3 As shown, the fixing frame 1 is rectangular in shape and includes a fixing plate 2 at the top of the fixing frame 1, a bottom frame at the bottom of the fixing frame 1, and a side frame connecting the fixing plate 2 and the bottom frame. The bottom frame is formed by a first horizontal bar 101 arranged along the length direction and a second horizontal bar 102 arranged along the width direction. The side frame is formed by a plurality of support rods 103 arranged along the vertical direction, thereby forming a frame for fixing the hanging basket.

[0038] In one possible embodiment, a foot cup is provided at the bottom of the support rod 103, so that the height of the fixing frame 1 can be adjusted according to the actual situation to accommodate different sizes of the welding basket.

[0039] Furthermore, the base frame is provided with a base plate 10, and the base plate 10 is provided with a driving component 16. The driving component 16 is provided with a tray 17 for supporting the basket to be welded, so that when needed, the height of the basket to be welded can be adjusted by the driving component 16 so that the part of the basket to be fixed reaches the height of the fixing plate 2. Figure 2 As shown, in one possible embodiment, the drive component 16 can be configured as a cylinder, which is fixed to the base frame by the base plate 10. Linear bushings are provided on both sides of the cylinder, and the tray 17 is fixed on the cylinder and moves up and down under the drive of the cylinder.

[0040] like Figure 1 and Figure 2 As shown, the first positioning element includes a first driving element 4 and a first fixing block 5 connected to the first driving element 4. The first driving element 4 drives the first fixing block 5 to move to contact the basket to be welded. In one possible embodiment, the first positioning element 4 is a cylinder, and the first fixing block 5 is fixed on the piston rod of the cylinder. When the cylinder is working, the first fixing block 5 is moved by the extension and retraction of the piston rod, thereby fixing the basket to be welded.

[0041] The movable component includes a second driving component 6 and a second fixing block 7 connected to the second driving component 6. The second driving component 6 drives the second fixing block 7 to move until it contacts the suspended platform to be welded. Since the movable component is used to fix the diagonal of the suspended platform to be welded, in order to prevent the fixed position of the movable component from deviating during fixing, in one possible embodiment, the second driving component 6 is set as a push-pull clamp. The position and force of pushing and operating the push-pull clamp are confirmed by personnel to confirm the fixed position of the push-pull clamp and control the force when fixing the suspended platform, thus ensuring the welding accuracy of the suspended platform during welding. Specifically, the second fixing block 7 is fixed to the outside of the push rod of the push-pull clamp. The operator manually pushes the push-pull clamp, and the push rod in the push-pull clamp extends outward, thereby pushing the second fixing block 7 to contact the suspended platform to be welded. The push-pull clamp is continued to be pushed until the second fixing block 7 is pressed tightly against the suspended platform to be welded, forming a fixation. After welding is completed, the operator manually pushes the push-pull clamp, and the push rod in the push-pull clamp retracts inward.

[0042] To improve the reliability of fixing the welding scaffold, in a preferred embodiment, the second positioning member includes two fixed members 8 and two movable members, such as... Figure 1 As shown, two fixed parts 8 and two movable parts are respectively located on both sides of the fixing slot 3, and are positioned near the diagonal of the fixing slot 3 to form a fixation at the diagonal of the hanging basket to be welded. The fixed parts 8 are located at the diagonal of the fixing slot 3, and their shape can be adjusted according to their position. For example, they can be set as follows: Figure 1 The L-shaped block or square shape shown is not limited to in this application.

[0043] To further improve the reliability of fixing the suspended platform to be welded, one of the two movable parts is oriented perpendicular to the longitudinal direction of the fixing slot 3, and the other is oriented at an angle of 40° to 50° to the longitudinal direction of the fixing slot 3, to ensure welding accuracy during the welding of the suspended platform. Preferably, the fixing effect is best when the angle between the direction of the obliquely oriented movable part and the longitudinal direction of the fixing slot 3 is 45°, which can ensure that the welding accuracy during the welding of the suspended platform is controlled within 1mm. The second fixing block 7 in the movable part abuts against the diagonal of the suspended platform to be welded, and its shape can be adjusted according to the fixing position. For example, when the movable part is obliquely oriented, it can be set to... Figure 1 As shown in the L-shaped block diagram, when the movable part is perpendicular to the longitudinal direction of the fixed slot 3, the second fixed block 7 in the movable part can be set as... Figure 1 The cube shape shown is not limited to any particular shape in this application.

[0044] The third positioning component includes a third driving component 9 and a third fixing block 10 connected to the third driving component 9. The third fixing block 10 is located on the side of the positioning rod 12 near the fixing slot 3. The third driving component 9 drives the third fixing block 10 to move until it contacts the basket to be welded. To make the third fixing block 10 more securely fix the cover plate fixing frame 18, a slot is formed on the third fixing block 10 extending from one end facing the fixing slot 3 to the other end away from the fixing slot 3. The slot can lock the cover plate fixing frame 18 to correct the position of the cover plate fixing frame 18 and facilitate welding.

[0045] Because the welding precision requirements for the cover plate fixing frame 18 are relatively high compared to other parts of the suspended platform, in one possible embodiment, the third driving component 9 is a push-pull clamp. By having personnel confirm the position and force of the push-pull clamp during pushing and operation, the accuracy of the third fixing block 10 being engaged on the cover plate fixing frame 18 is ensured, and the force applied by the third fixing block 10 when fixing the cover plate fixing frame 18 is controlled, thus guaranteeing the welding precision of the suspended platform to be welded. Specifically, the worker manually pushes the push-pull clamp, causing the push rod in the clamp to extend outwards, thereby pushing the third fixing block 10 to move into the slot and engage the cover plate fixing frame 18. The push rod in the push-pull clamp then forms a fixed connection. After welding is completed, the worker manually pushes the push-pull clamp, causing the push rod in the clamp to retract inwards.

[0046] In one possible embodiment, the third fixing block 10 is provided with stop blocks 11 on both sides. The stop blocks 11 are arranged along the longitudinal direction of the fixing groove 3 and fit with the third fixing block 10, thereby limiting the position of the third fixing block and further improving the welding accuracy of the hanging basket.

[0047] like Figure 1 and Figure 2 As shown, the positioning pin includes a positioning rod 12 connected to the fixing plate 2 and a positioning plate 13 connected to the positioning rod 12. The positioning plate 13 is located on the top of the positioning rod 12. Both the first end of the positioning plate 13 and the positioning rod 12 have through holes. The positioning plate 13 is connected to the positioning rod 12 by bolts passing through the through holes. The second end of the positioning plate 13 has a protrusion 14. When fixing the basket to be welded, the positioning plate 13 is pressed down onto the cover plate fixing frame 18 by the operator, so that the protrusion 14 is inserted into the groove on the cover plate fixing frame 18 of the basket to be welded, thereby correcting and fixing the position of the groove on the cover plate fixing frame 18.

[0048] It should be noted that the number of positioning pins and the number of slots on the third fixing block 10 are set according to the number of cover plate fixing brackets 18 on the basket to be welded. In this embodiment, two positioning pins are provided on one side of the fixing slot 3, and two slots are provided on one third fixing block 10. In other possible embodiments, more positioning pins and slots can be provided, which are not limited here.

[0049] The order in which the first positioning member, the second positioning member, the third positioning member, and the positioning pin fix the basket to be welded in the above embodiments can be set according to the actual situation. As a preferred embodiment, the order in which the fixing device for basket welding fixes the basket to be welded is as follows: the basket to be welded is placed in the fixing slot 3, the drive member 16 is turned on, the basket to be welded is raised to the preset fixed height, the first positioning member is turned on, and the basket to be welded is fixed on both sides along the width direction. The drive member 16 is turned off and the oblique movable member is pushed to fix one opposite corner of the basket to be welded. Then the movable member that is perpendicular to the longitudinal direction of the fixing slot 3 is pushed to fix the other opposite corner of the basket to be welded. The positioning pin is rotated so that the protrusion 14 of the positioning plate 13 is inserted into the groove of the cover plate fixing frame 18. The third drive member 9 is pushed so that the third fixing block 10 is stuck in the cover plate fixing frame 18 and welding begins.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
