Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and in particular to a workbench for assembling switch covers. Background Technology

[0002] Rotary assembly tables are a common type of equipment in the automated production of precision electronic components such as switch covers. These tables typically use a turntable to mount multiple molds, and the rotation of the turntable sequentially feeds the molds to different workstations such as loading, assembly, and unloading, thereby achieving continuous assembly line operation and significantly improving production efficiency.

[0003] In the assembly process described above, the mold, as a key component for supporting and positioning the workpiece, directly affects the efficiency and flexibility of the entire production line due to its installation stability and ease of replacement. Frequent mold replacements are necessary to produce different models of switch covers or to maintain the molds.

[0004] Most existing mold installation methods use bolts or pressure plates for fastening. This method requires operators to loosen or tighten each bolt individually during assembly and disassembly, which is not only cumbersome and time-consuming but also typically requires specialized tools such as wrenches, resulting in low automation of the mold changeover process. Especially in flexible production models that pursue small batches and multiple varieties, this inefficient mold changeover method has become a significant bottleneck restricting the improvement of overall production efficiency.

[0005] Therefore, this utility model proposes a workbench for assembling switch covers to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome and time-consuming mold installation and replacement processes in the existing switch cover assembly workbench, which leads to low production line changeover efficiency, this utility model aims to provide a switch cover assembly workbench with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a workbench for assembling a switch cover, including an operating table, a turntable rotatably mounted on the operating table via a rotating shaft, a mold detachably mounted on the turntable, and a fixing mechanism mounted on the turntable to cooperate with the mold.

[0008] The bottom of the mold is provided with a fixing post that extends downward and has a slot on its outer peripheral wall.

[0009] Furthermore, the fixing mechanism includes a fixing chamber, a semi-circular limiting plate, and a damping column 1 disposed within the turntable. The semi-circular limiting plate is movably disposed on the turntable. One end of the damping column 1 abuts against the inner wall of the fixing chamber, and the other end abuts against and pushes the semi-circular limiting plate so that the semi-circular limiting plate is engaged in the slot of the fixing column.

[0010] Preferably, the fixing mechanism further includes a connecting plate, and the connecting plate is fixedly connected to a plurality of semi-circular limiting plates.

[0011] Preferably, the worktable for assembling the switch cover further includes an auxiliary component, which includes a control ring that can be vertically moved and a push rod that is driven to disengage the semicircular limiting plate from the slot.

[0012] Preferably, the auxiliary component further includes a fixed disk, a connecting rod, a connecting block, and a push block. The control ring is slidably disposed on the fixed disk and is connected to the push rod in sequence through the connecting rod, the connecting block, and the push block.

[0013] Preferably, the auxiliary component further includes a spring, which is disposed on the outer periphery of the connecting rod.

[0014] Preferably, the auxiliary component further includes a first fixing block, a first damping rod, and a second fixing block. The first fixing block is fixed to the fixed chamber, and the second fixing block is fixedly connected to the push rod and slidably sleeved on the first damping rod supported by the first fixing block.

[0015] Preferably, the workbench for assembling the switch cover further includes a support mechanism disposed between the turntable and the operating table. The support mechanism includes a plurality of damping columns arranged in the vertical direction and springs connected in parallel to the damping columns.

[0016] Preferably, the support mechanism further includes a support bar and a rotating wheel, with the bottom ends of the plurality of damping columns connected to the support bar, and the rotating wheel rotatably disposed on the bottom surface of the support bar and rollingly supported on the operating table.

[0017] Preferably, the support mechanism further includes a second damping rod, a first limiting block, and a second limiting block. The first limiting block is fixed to the support bar, the second limiting block is fixed to the bottom surface of the turntable, and the two ends of the second damping rod are rotatably connected to the first limiting block and the second limiting block, respectively.

[0018] Preferably, the operating table is also equipped with a feeding machine and a discharging machine that cooperate with the mold.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model solves the problems of complex mold installation process, tool assistance, and long time consumption in the prior art by setting a fixed column with a slot at the bottom of the mold and setting a semi-circular limiting plate on the turntable that cooperates with it and is pushed by the damping column. It achieves the convenient installation effect of automatic locking when the mold is pressed down, which greatly shortens the mold change time and improves production efficiency.

[0021] 2. This utility model, by setting an auxiliary component driven by a control ring, utilizes the linkage of connecting rods and push rods to make the semi-circular limiting plate quickly disengage from the slot of the fixed column, solving the problems of cumbersome mold disassembly, reliance on tools, and poor production changeover flexibility in the prior art. It achieves the effect of quickly releasing the mold with a simple lifting action, realizing tool-free mold changeover and enhancing the flexibility of the production line.

[0022] 3. This utility model solves the problem in the prior art where vibration affects placement accuracy and assembly quality when the rotary table is running at high speed or interacting with the robotic arm. It solves the problem by setting a support mechanism composed of damping columns, springs and damping rods between the turntable and the operating table. It achieves the technical effect of effectively absorbing and buffering vibration during operation and ensuring the smooth operation of the turntable, thereby ensuring the accuracy of automated assembly and improving the product qualification rate.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] Example:

[0039] Please refer to Figures 1 to 8 This utility model provides a workbench for assembling switch covers, which aims to solve the problems of cumbersome and time-consuming mold installation and replacement processes in the prior art, as well as the impact of vibration generated during workbench operation on assembly accuracy.

[0040] like Figure 1 and Figure 2 As shown, the workbench for assembling the switch cover includes an operating table 1 and a turntable 3 rotatably mounted on the operating table 1 via a rotating shaft 2. The operating table 1 serves as the mounting base for the entire device, providing a mounting platform for other components. The top of the turntable 3 is used to detachably mount the mold 4. The turntable 3 rotates under the drive of the rotating shaft 2 to achieve the switching of work positions. The operating table 1 is also equipped with a feeding machine 7 and a discharging machine 8 that cooperate with the mold 4 on the turntable 3. The feeding machine 7 is used to place the workpiece to be processed into the mold 4, and the discharging machine 8 is used to remove the finished product from the mold 4.

[0041] One of the core aspects of this embodiment is that it provides a structure for quickly fixing the mold 4. Please refer to... Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8The bottom of the mold 4 is provided with a downwardly extending fixing post 51, and the outer peripheral wall of the fixing post 51 is provided with a locking groove. The turntable 3 is provided with a fixing mechanism 5 that cooperates with the fixing post 51. The fixing mechanism 5 is used to automatically lock the mold 4 during installation. The detailed structure of the fixing mechanism 5 includes a fixing chamber 54 set inside the turntable 3, which provides housing space and support for the internal components. A semi-circular limiting plate 52 is slidably set on the turntable 3. The shape of the semi-circular limiting plate 52 is adapted to the groove of the fixing post 51, and is used to engage or disengage from the groove of the fixing post 51, thereby realizing the fixing. The axial positioning of column 51; one end of damping column 53 abuts against the inner wall of the fixed chamber 54, and the other end abuts against and pushes the semi-circular limiting plate 52, so that the semi-circular limiting plate 52 always tends to move towards the position of being inserted into the slot, thereby automatically locking the fixed column 51 when there is no external force intervention; in order to ensure the consistency of the movement of multiple semi-circular limiting plates 52, the fixing mechanism 5 also includes a connecting plate 55, which is fixedly connected to multiple semi-circular limiting plates 52. When one semi-circular limiting plate 52 moves, the other semi-circular limiting plates 52 can be driven to move synchronously through the transmission action of the connecting plate 55.

[0042] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the workbench for assembling the switch cover also includes an auxiliary component 56 for quickly releasing the mold 4, and the auxiliary component 56 and the aforementioned fixing mechanism 5 form a specific structural fit and transmission connection relationship.

[0043] Please refer to the following carefully. Figure 2 , Figure 5 and Figure 6 The release structure of this core will be explained in detail below:

[0044] Auxiliary component 56 includes a vertically movable control ring 569, which slides through a fixed plate 501 fixed on the turntable 3. The operator initiates the unlocking process by lifting the control ring 569. A connecting rod 567 is fixedly connected to the bottom end of the control ring 569, and the other end of the connecting rod 567 is connected to a connecting block 566. A push block 565 is fixedly connected to the connecting block 566, and the push block 565 is slidably connected to the push rod 564. When the control ring 569 moves upward, it pulls the connecting block 566 upward simultaneously. During the upward movement of the connecting block 566, it pushes the two push rods 564 slidably connected at the top of the connecting block 566 to slide on the inner wall of the turntable 3. The two push rods 564 move towards the opposite side of the two push rods 564 as the connecting block 566 pushes them. This movement of the push rods 564 drives the fixed block 563. The push rod 564 moves synchronously, while multiple fixed blocks 563 are fixedly connected to fixed blocks 561 via damping rods 562 fixed on opposite sides. The adjacent sides of multiple fixed blocks 561 are fixedly connected to the front and rear sides of the two fixed chambers 54. The fixed connection between fixed blocks 561 and fixed chambers 54 provides guidance and support for the movement of the push rod 564, making the movement of the push rod 564 more stable. Since fixed blocks 563 are fixedly connected to connecting plates 55, the connecting plates 55 move synchronously during the movement of the push rod 564. This causes the two connecting plates 55 to move to opposite sides, causing the semi-circular limiting plates 52 fixedly connected to the adjacent sides of the two connecting plates 55 to leave the fixing post 51 and release it. Finally, the semi-circular limiting plates 52 are released from the slots of the fixing post 51, completing the release of the mold 4.

[0045] To ensure the stability and reset of the auxiliary component 56, its internal structure is further optimized. The auxiliary component 56 also includes a spring 568, which is sleeved on the outer periphery of the connecting rod 567. Its two ends abut against the fixed plate 501 and the connecting block 566, respectively, to provide a downward reset force for the control ring 569 and related actuators after the external force is released. At the same time, to provide guidance and buffer for the lateral movement of the push rod 564, the auxiliary component 56 also includes a fixed block 561, a damping rod 562, and a fixed block 563. The fixed block 561 is fixed to the fixed chamber 54, one end of the damping rod 562 is fixed to the fixed block 561, and the fixed block 563 is fixedly connected to the push rod 564 and slides on the damping rod 562. This guide rail slider structure ensures the smoothness and accuracy of the push rod 564 during movement.

[0046] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0047] In a preferred embodiment, in order to further improve the stability of the workbench during high-speed operation and effectively absorb vibration, a support mechanism 6 is also provided between the turntable 3 and the operating table 1. The support mechanism 6 includes multiple damping columns 61 arranged in the vertical direction and springs 67 connected in parallel with them. The top of the damping column 61 is connected to the bottom surface of the turntable 3. The damping column 61 and the spring 67 together provide vertical buffering and support for the turntable 3.

[0048] Based on the aforementioned support mechanism 6, the mechanism may further include a support bar 62 and a rotating wheel 63; the bottom ends of multiple damping columns 61 are uniformly connected to the top surface of the support bar 62, while a rotating wheel 63 is rotatably arranged on the bottom surface of the support bar 62. The rotating wheel 63 is rolled and supported on the operating table 1, providing low-friction rolling support for the rotation of the turntable 3; to enhance lateral stability, the support mechanism 6 may further include a damping rod 65, a limiting block 64, and a limiting block 66. The limiting block 64 is fixed to the support bar 62, the limiting block 66 is fixed to the bottom surface of the turntable 3, and the two ends of the damping rod 65 are rotatably connected to the limiting block 64 and the limiting block 66 respectively, for synergistic absorption of lateral impacts and vibrations.

[0049] The working principle is as follows:

[0050] First, there is the process of installing and fixing the mold 4. When the mold 4 is placed on the top of the turntable 3, the weight of the mold 4 itself or the applied downward pressure will cause the fixing column 51 at its bottom to move downward. When the fixing column 51 moves to the predetermined position, the slot opened on its outer peripheral wall aligns with the semi-circular limiting plate 52. At this time, the damping column 53, which always provides support in the fixing chamber 54, will push the semi-circular limiting plate 52 to move horizontally, so that it is locked into the slot of the fixing column 51, thereby achieving axial locking of the fixing column 51, and thus quickly and firmly fixing the entire mold 4 on the turntable 3. During this process, the connecting plate 55 ensures that the multiple semi-circular limiting plates 52 that cooperate with the multiple fixing columns 51 can move synchronously, avoiding fixing failure caused by inconsistent movements.

[0051] Secondly, there is the process of releasing and replacing mold 4. When mold 4 needs to be replaced, pull up the control ring 569. The control ring 569 drives the push rod 564 to expand to both sides through the transmission chain composed of the connecting rod 567, the connecting block 566, and the push block 565. The expansion movement of the push rod 564 will directly push the connecting plate 55, causing all the semi-circular limit plates 52 to overcome the thrust of the damping column 53 and simultaneously disengage from the slot of the fixed column 51. At this time, the locking of the fixed column 51 is released, and the mold 4 can be easily removed upwards. During the entire release action, the fixed block 563 slides along the damping rod 562 supported by the fixed block 561, providing stable guidance and buffer for the movement of the push rod 564, while the spring 568 ensures that the entire auxiliary component 56 can automatically reset after the control ring 569 is released.

[0052] Finally, there is the stable operation and vibration reduction process of the worktable. When the turntable 3 rotates under the drive of the rotating shaft 2 or interacts with external equipment such as the loading machine 7 and unloading machine 8, the resulting vibrations are transmitted to the support mechanism 6. Vertical vibrations are mainly absorbed and buffered by the damping column 61 and the spring 67, while horizontal or more complex vibrations are buffered by the damping rod 65 connected between the turntable 3 and the support bar 62. At the same time, the roller 63 at the bottom of the support bar 62 rolls smoothly on the operating table 1, providing low-friction support for the rotation of the turntable 3. Through this combination of multiple vibration reduction and stable support, the stability of the worktable operation is effectively guaranteed, ensuring the accuracy of the assembly process.
