Description

Technical Field

[0001] This application relates to the field of terminal assembly technology, and in particular to an assembly apparatus for terminals and plastic sheets. Background Technology

[0002] In the production and assembly process of electrical products such as relays, plastic sheets need to be assembled into the terminal slots of the product base through their retaining posts in order to connect with other components.

[0003] Traditional assembly methods generally use linear displacement to drive plastic sheet pins to directly insert into terminal slots. However, some products with special structures (such as certain relay models) have raised obstacle points on their bases. These obstacle points block the linear assembly path of the plastic sheet, preventing the plastic sheet pins from being properly aligned and inserted into the terminal slots. This directly causes the assembly operation to be impossible and severely limits the applicability of traditional assembly devices. Summary of the Invention

[0004] The purpose of this application is to propose an assembly device for terminals and plastic sheets to solve the problem that in traditional linear displacement assembly methods, the protruding obstacles of the special structure product base block the linear assembly path of the plastic sheet, causing the plastic sheet clamping post to be unable to be aligned and inserted into the terminal clamping hole, making the assembly operation impossible, and the application scope of traditional devices is limited.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] An assembly device for terminals and plastic sheets, comprising:

[0007] The bracket is equipped with an adjustment mechanism;

[0008] A connector is installed on the adjusting mechanism, which adjusts the spatial position of subsequent components by driving the connector to move.

[0009] A rotary clamping mechanism is installed on the connector. The rotary clamping mechanism has a clamping part for clamping a plastic sheet, and the clamping part can rotate in both directions around its own axis.

[0010] The adjustment mechanism drives the connector and the rotating clamping mechanism to move, so that the locking post of the plastic sheet moves toward the locking hole of the terminal. The clamping part of the rotating clamping mechanism rotates forward in a tilted state to avoid obstacles on the product base and make the locking post of the plastic sheet pass through the locking hole of the terminal. After the rotating clamping mechanism rotates in the opposite direction, it becomes vertical and the end of the plastic sheet away from the locking post is embedded in the locking slot of the product base.

[0011] The adjustment mechanism includes an adjustment component and a guide component; both the adjustment component and the guide component are mounted on the bracket, and the guide component is connected to the adjustment component, while the adjustment component is also connected to the connector; the guide component is used to guide and support the connector driven by the adjustment component, and its guiding direction is set along the central axis of the terminal's locking hole; the adjustment component is used to drive the connector to move closer to or away from the terminal locking hole in the direction directly opposite to it;

[0012] The adjustment mechanism is an XYZ three-axis linear module, which realizes the position adjustment of the connector in the X, Y and Z directions;

[0013] The XYZ three-axis linear module includes a movable frame, an X-line module, a Y-moving module, a Z-moving module, and a sliding member. The X-line module is mounted on the bracket, and its length direction is parallel to the guiding direction of the guide member. The movable frame is perpendicularly mounted on the X-line module, and the guide member is also connected to the movable frame. The Y-moving module and the Z-moving module are both mounted on the movable frame, and the length direction of the Y-moving module is perpendicular to the length direction of the X-line module and the length direction of the Z-moving module. The Y-moving module is slidably connected to the connecting member, and the direction in which the connecting member slides relative to the Y-moving module is the same as the length direction of the Z-moving module. The end of the connecting member away from the rotating clamping mechanism is slidably connected to the Z-moving module through the sliding member, and the direction in which the connecting member slides relative to the Z-moving module is the same as the length direction of the Y-moving module.

[0014] The rotary clamping mechanism includes an angle adjustment structure, a clamping structure, and a mating part; the angle adjustment structure is disposed on the connector, the clamping part is a clamping structure, the clamping structure is disposed on the angle adjustment structure, the clamping structure has two clamping claws for clamping plastic sheets, the number of mating parts is two and they are respectively disposed on the two clamping claws of the clamping structure, and the opposite sides of the two mating parts are provided with positioning grooves that match the shape of the plastic sheet;

[0015] The clamping structure is provided with an extension portion, and the extension portion is provided with a limiting block extending to the space between the two clamping claws of the clamping structure.

[0016] The angle between the locking post and the terminal of the plastic sheet in the tilted state is 45°–75°.

[0017] The sliding component includes a guide rail, roller shafts, a sliding plate, a traction rod, and an elastic element. The guide rail is disposed on the Z-movement module, and the length direction of the guide rail is in the same direction as the length direction of the Y-movement module. The sliding plate is slidably mounted on the end of the connector opposite to the rotating clamping mechanism. The end of the connector opposite to the rotating clamping mechanism is higher than the sliding plate and the guide rail, and the sliding direction of the sliding plate is perpendicular to the length direction of the guide rail. There are multiple roller shafts, which are respectively disposed on the sliding plate and the connector. The roller shafts disposed on the sliding plate and the roller shafts disposed on the connector are respectively placed on both sides of the guide rail and slidably connected to the guide rail. There are two traction rods, which are respectively disposed on the sliding plate and the end of the connector higher than the sliding plate, and the two traction rods are elastically connected to each other through the elastic element.

[0018] Optionally, the device also includes a mounting bracket equipped with a clamping locator for clamping and positioning the product to be assembled with plastic sheets.

[0019] Optionally, the mounting bracket and the clamping locator are slidably connected.

[0020] Compared to existing technologies, the beneficial effects of this application are:

[0021] 1. Breaking through the limitations of traditional assembly, the device solves the assembly problem of special products with protruding obstacles by rotating and avoiding obstacles, thus broadening the scope of application of the device.

[0022] 2. Fully automated operation, no need for manual intervention to avoid obstacles, improving assembly efficiency and reducing labor costs and assembly errors.

[0023] 3. The positioning mechanism includes a guide structure and an XYZ three-axis linear module, which enables precise positioning in three-dimensional space, improves the alignment accuracy of the clamping post and the clamping hole, enhances motion stability, and is suitable for multiple scenarios such as material picking, assembly, and obstacle avoidance.

[0024] 4. The elastically adjustable sliding component reduces the impact of friction and clearance, further improving the positioning accuracy of the rotary clamping mechanism and ensuring assembly stability.

[0025] 5. The rotary clamping mechanism precisely clamps the plastic sheet through the matching positioning groove. The 45°–75° tilt angle takes into account both avoidance and assembly requirements. The limit block prevents damage from over-clamping and improves clamping reliability. Attached Figure Description

[0043] In this embodiment, by Figure 1-11 An assembly device for a terminal 93 and a plastic sheet 96 is provided, comprising a bracket 1, a connector 3, and a rotating clamping mechanism 4.

[0044] This application is mainly used for products that require obstacle avoidance during assembly, such as relays 9, and will be used as an example thereafter. In some special relays 9, there is a protrusion, or obstacle point 92, on the base 91 of the relay 9. The traditional assembly method is to use linear displacement to directly assemble the retaining post 961 of the plastic piece 96 into the terminal 93 retaining hole 94 on the base 91. However, in some special relays 9, assembly is not possible due to the presence of obstacle point 92. Therefore, this application uses the method of rotating the plastic piece 96 to avoid obstacle point 92 on the base 91 of the relay 9, and then uses linear displacement to assemble the retaining post 961 of the plastic piece 96 into the terminal 93 retaining hole 94 on the base 91, as detailed below:

[0045] The bracket 1 consists of a base frame and a support plate mounted on the base frame. It mainly supports the main body of the device. The support plate of the bracket 1 is equipped with an adjustment mechanism 2. The adjustment mechanism 2 uses a threaded screw and a slider to adjust the position of the connected parts, such as a linear slide table. Of course, it can also use an electric push rod and a cylinder. Its function is to adjust the connected parts and the plastic sheet 96.

[0046] The connector 3 is installed on the adjustment mechanism 2. Its function is to connect the rotary clamping mechanism 4. This is because there is a certain height difference between the moving end of the adjustment mechanism 2 and the relay 9. When directly connected, the rotary clamping mechanism 4 cannot directly correspond to the base 91 of the relay 9. Therefore, the connector 3 is used. The adjustment mechanism 2 indirectly adjusts the spatial position of the rotary clamping mechanism 4 and the plastic sheet 96 clamped by the rotary clamping mechanism 4 by driving the connector 3 to move.

[0047] The rotary clamping mechanism 4 is installed on the connector 3. The rotary clamping mechanism 4 is the output end of this device. It consists of two structures: a rotary function and a clamping function. Specifically, the rotary clamping mechanism 4 has a clamping part for clamping the plastic sheet 96, and the clamping part can also rotate in both directions around its own axis.

[0048] In this mechanism, the adjusting mechanism 2 drives the connecting piece 3 and the rotating clamping mechanism 4 to move, causing the locking post 961 of the plastic sheet 96 to move closer to the locking hole 94 of the terminal 93. Simultaneously, the clamping part of the rotating clamping mechanism 4 rotates forward and tilts. Figure 2 As shown, the obstruction point 92 on the product base 91 is avoided and the locking post 961 of the plastic sheet 96 is inserted into the locking hole 94 of the terminal 93. After the rotary clamping mechanism 4 is rotated in the opposite direction, it is in a vertical state, as shown. Figure 3 As shown, the end of the plastic sheet 96 away from the locking post 961 is embedded in the locking slot 95 of the product base 91.

[0049] More specifically, the clamping part of the rotary clamping mechanism 4 first clamps the plastic sheet 96, and the adjusting mechanism 2 drives the connector 3 installed on it to move, thereby driving the rotary clamping mechanism 4 connected to the connector 3 to move according to a preset path, so that the locking post 961 of the plastic sheet 96 gradually moves towards the locking hole 94 of the relay terminal 93. During this process, the clamping part of the rotary clamping mechanism 4 rotates synchronously in the forward direction, so that the plastic sheet 96 is tilted to avoid the protruding obstacle point 92 on the product base 91, ensuring that the locking post 961 of the plastic sheet 96 is smoothly inserted into the locking hole 94 of the terminal 93. After the locking post 961 is inserted into place, the clamping part of the rotary clamping mechanism 4 rotates in the reverse direction to return to the vertical state, so that the end of the plastic sheet 96 away from the locking post 961 is accurately embedded in the locking slot 95 of the product base 91, completing the assembly of the plastic sheet 96 and the terminal 93.

[0050] In summary, for special products with protruding obstacle points 92, such as special relays 9, the limitations of traditional linear displacement assembly methods, which cannot be assembled due to obstruction by obstacle points 92, are overcome. By cooperating with the adjusting mechanism 2 and the clamping part that can rotate in both directions, the tilting avoidance and precise assembly of the plastic sheet 96 are achieved. This ensures the smoothness of the assembly process and improves the accuracy of the assembly position. It effectively adapts to the needs of products that require obstacle avoidance during assembly, broadens the application range of the assembly device, and the entire assembly process does not require manual intervention to avoid obstacle points 92, thereby improving assembly efficiency and automation, and reducing manual operation costs and assembly errors.

[0051] In order to improve the assembly accuracy of the plastic sheet 96 and the terminal 93 and ensure that the locking post 961 of the plastic sheet 96 is accurately aligned with the locking hole 94 of the terminal 93, an adjustment mechanism 2 with a guiding structure is adopted.

[0052] Specifically, refer to Figure 5As shown, the adjustment mechanism 2 includes an adjustment component 21 and a guide component 22;

[0053] The adjustment component 21 and the guide component 22 are both mounted on the support plate of the bracket 1, and the guide component 22 is connected to the adjustment component 21. The adjustment component 21 is also connected to the connector 3. The guide component 22 is used to guide and support the connector 3 driven by the adjustment component 21, and its guiding direction is set along the central axis of the locking hole 94 of the terminal 93. The adjustment component 21 is used to drive the connector 3 to move closer to or away from the locking hole 94 of the terminal 93 in the direction directly opposite to the locking hole 94 of the terminal 93.

[0054] The guide component 22 consists of a slide rail and a slider. The slide rail is directly mounted on the support plate of the bracket 1, and its length direction is set along the central axis of the locking hole 94 of the terminal 93, that is, the direction in which the plastic sheet 96 locking post 961 moves linearly and assembles the locking hole 94 of the terminal 93. The slider is slidably mounted on the slide rail and is also connected to the adjustment component 21.

[0055] The adjustment mechanism 2 provides driving force through the adjustment component 21, driving the connected connector 3 to move closer to or further away from the terminal 93 slot 94 along the direction of the central axis of the terminal 93 slot 94. At the same time, the guide component 22 guides and supports the movement of the connector 3, and the guiding direction is in the same direction as the central axis of the terminal 93 slot 94, ensuring that the connector 3 drives the subsequent rotating clamping mechanism 4 and the plastic sheet 96 to move accurately, so that the plastic sheet 96 slot 961 can be accurately aligned with the terminal 93 slot 94, laying a precise positional foundation for subsequent rotational avoidance assembly.

[0056] The alignment of the plastic sheet 96 pin 961 and the terminal 93 hole 94 is effectively improved by the cooperation of the adjustment component 21 and the guide component 22, avoiding assembly errors caused by movement and offset. The supporting role of the guide component 22 enhances the stability of the adjustment process and reduces the impact of vibration on the assembly accuracy. The structure is simple and the guidance is accurate, which can be adapted to the scenario that requires high-precision assembly, improves the overall assembly quality and efficiency, and reduces the defect rate.

[0057] Reference Figure 5As shown, considering that the rotary clamping mechanism 4 needs to move to a predetermined position for material handling before assembling the plastic sheet 96 onto the terminal 93, the preferred adjustment mechanism 2 is an XYZ three-axis linear module. This is because the XYZ three-axis linear module allows for position adjustment of the connector 3 and the rotary clamping mechanism 4 in the X, Y, and Z directions. The X and Y directions correspond to the length and width of the platform where the relay 9 is placed, respectively, while the Z direction is the height direction perpendicular to the platform. As long as the direction of one axis is aligned with the central axis of the terminal 93's locking hole 94, that is, the direction in which the plastic sheet 96 locking post 961 moves linearly and assembles the terminal 93's locking hole 94. In conjunction with the movement in the other two directions (and the three directions are set perpendicular to each other), the rotary clamping mechanism 4 can be moved to any position in the space. This not only meets the requirement of assembling the plastic sheet 96 onto the terminal 93 by the linear movement of the rotary clamping mechanism 4, but also allows the rotary clamping mechanism 4 to be adjusted to a specific position for material removal. At the same time, considering that this device is only one process in the equipment for producing relays 9, the assembled and semi-finished relays 9 need to be conveyed to the next process. The space cannot obstruct the relays 9. Before the relays 9 with assembled plastic sheets 96 are conveyed to the next process, the rotary clamping mechanism 4 can be controlled to avoid the relays 9 in the height direction.

[0058] Based on the foregoing, the guide member 22 only limits the rotation clamping mechanism 4 in the direction of linear movement of the plastic sheet 96 pin 961 and assembly of the terminal 93 pin hole 94 (direction of the central axis of the pin hole 94), but the rotation clamping mechanism 4 moves and is guided in the other two directions. In order to further improve the accuracy and stability of the rotation clamping mechanism 4 in the other two directions, an XYZ three-axis linear module with guidance in the other two directions is adopted.

[0059] Specifically, refer to Figure 5 As shown, the XYZ three-axis linear module includes a moving frame 211, an X linear module 212, a Y moving module 213, a Z moving module 214, and a sliding member 215.

[0060] The X-axis linear module 212 is mounted on the support plate of the bracket 1. The length direction of the X-axis linear module 212 is parallel to the guiding direction of the guide member 22. Furthermore, the direction in which the X-axis linear module 212 adjusts the position of the rotating clamping mechanism 4 corresponds to the direction in which the plastic sheet 96 pin 961 moves linearly and assembles the terminal 93 slot 94. Figure 5 The direction of the X-axis, i.e., the direction of the central axis of the caliper 94.

[0061] Furthermore, to facilitate the installation of the Y-moving module 213 and the Z-moving module 214, the moving frame 211 is vertically mounted on the X-linear module 212. The slider on the guide 22 is also connected to the moving frame 211. The guide rail and the slider cooperate with each other to limit the movement of the moving frame 211. At the same time, this makes the direction more accurate when the X-linear module 212 moves the moving frame 211, and also shares the weight of the moving frame 211 and the components connected to the moving frame 211 with the X-linear module 212.

[0062] Both the Y-moving module 213 and the Z-moving module 214 are mounted on the moving frame 211. The length direction of the Y-moving module 213 is perpendicular to the length direction of the X-linear module 212, and the length direction of the Y-moving module 213 is perpendicular to the length direction of the Z-moving module 214. The Y-moving module 213 adjusts the position of the rotating clamping mechanism 4. Figure 5 The Y-axis direction is the direction in which the vertical plastic sheet 96 pin 961 moves linearly and assembles the terminal 93 pin hole 94. Figure 5 (in the X-axis direction), while the Z-movement module 214 adjusts the direction of the position of the rotary clamping mechanism 4 (in the X-axis direction). Figure 5 The Z-axis direction is perpendicular to the direction in which the plastic sheet 96 pins 961 move linearly and assemble the terminal 93 mounting hole 94. Figure 5 The X-axis direction and the Y-axis direction of the moving module 213 adjust the position of the rotating clamping mechanism 4. Figure 5 The plane formed by the Y-axis direction.

[0063] Furthermore, to prevent one of the Y-moving modules 213 and Z-moving modules 214 from being obstructed by the other when adjusting the position of the rotating clamping mechanism 4, the Y-moving module 213 is slidably connected to the connector 3. The direction in which the connector 3 slides relative to the Y-moving module 213 is the same as the length direction of the Z-moving module 214. The end of the connector 3 facing away from the rotating clamping mechanism 4 is slidably connected to the Z-moving module 214 via the slider 215. The direction in which the connector 3 slides relative to the Z-moving module 214 is the same as the length direction of the Y-moving module 213. This ensures that when either the Y-moving module 213 or the Z-moving module 214 moves the rotating clamping mechanism 4 via the connector 3, the connector 3 will be slidably connected to the other module, and the sliding direction will be consistent with the direction of movement, without being obstructed in movement.

[0064] This XYZ three-axis linear module achieves precise positioning and movement of the rotary clamping mechanism 4 in three-dimensional space through the coordinated operation of linear modules in the X, Y, and Z directions. The X linear module 212 follows the guiding direction of the guide member 22 (corresponding to the assembly direction of the plastic sheet 96 and the clamping post 961, i.e....). Figure 5The X-axis direction drives the moving frame 211 to move. The guide rail and slider of the guide member 22 cooperate to limit the movement of the moving frame 211, ensuring accurate movement in the X direction and distributing the weight. The Y moving module 213 and the Z moving module 214 are set perpendicularly to each other on the moving frame 211. Their positions are adjusted along the Y-axis perpendicular to the X-axis and the Z-axis perpendicular to the XY-axis plane, respectively. The Y module is slidably connected to the connecting member 3 along the Z-axis, and the Z module is slidably connected to the connecting member 3 along the Y-axis through the sliding member 215. This ensures that the Y and Z modules do not obstruct each other during adjustment, thereby driving the rotary clamping mechanism 4 to move flexibly and accurately in three-dimensional space to meet assembly requirements.

[0065] In summary, the triaxial orthogonal layout and sliding connection not only compensate for the deficiency of the guide component 22 in limiting only the X direction, but also achieve precise guidance and stable movement in the Y and Z directions, significantly improving the overall positioning accuracy and motion stability of the rotary clamping mechanism 4; the non-interference of the Y and Z modules avoids motion obstruction, ensures the smoothness of the adjustment process, further improves the assembly accuracy and efficiency of the plastic sheet 96 and the terminal 93, and reduces the defect rate.

[0066] Considering the efficiency of generating relay 9, the adjustment of the XYZ three-axis linear module needs to be fast. This process will generate vibration and slight displacement. In order to avoid slip instability caused by vibration or gap, and thus ensure the motion accuracy of the rotary clamping mechanism 4 when adjusting the Y and Z modules, a sliding member 215 with elastic adjustment is adopted.

[0067] Specifically, refer to Figure 7 and Figure 8 As shown, the sliding member 215 includes a guide rail 2151, a roller shaft 2152, a sliding plate 2153, a pulling rod 2154, and an elastic member 2155. The guide rail 2151 is disposed on the Z-moving module 214, and the length direction of the guide rail 2151 is in the same direction as the length direction of the Y-moving module 213. The sliding plate 2153 is slidably mounted on the end of the connecting member 3 away from the rotating clamping mechanism 4. The end of the connecting member 3 away from the rotating clamping mechanism 4 is higher than the sliding plate 2153 and the guide rail 2151, and the sliding direction of the sliding plate 2153 is the same as that of the guide rail 2154. 51 is perpendicular in length direction. There are multiple roller shafts 2152, which are respectively set on the slide plate 2153 and the connector 3. The roller shafts 2152 set on the slide plate 2153 and the roller shafts 2152 set on the connector 3 are respectively placed on both sides of the guide rail 2151 and are slidably connected to the guide rail 2151. There are two pull rods 2154, which are respectively set on the slide plate 2153 and the end of the connector 3 above the slide plate 2153. The two pull rods 2154 are elastically connected to each other through the elastic member 2155.

[0068] More specifically, the slider 215 achieves its sliding function through the cooperation of the guide rail 2151 and the roller shaft 2152. The guide rail 2151 is fixed to the Z-movement module 214 and its length direction is consistent with that of the Y-movement module 213. The slide plate 2153 can slide on the connector 3 along a direction perpendicular to the length of the guide rail 2151 (for example, by means of a slide rail and a slider). Multiple roller shafts 2152 are respectively installed on the slide plate 2153 and the connector 3 and placed on both sides of the guide rail 2151, so that the connector 3 can slide along the length direction of the guide rail 2151 (i.e., ...). Figure 6 The roller shaft 2152 slides smoothly in the Y-axis direction. At the same time, the elastic element 2155 connects the slide plate 2153 and the pull rod 2154 on the connector 3. The elastic force ensures that the roller shaft 2152 is always in close contact with the guide rail 2151, avoiding loosening or displacement during the sliding process.

[0069] The advantage of using the elastically adjustable slider 215 lies in the structure of the roller shaft 2152 cooperating with the guide rail 2151, which greatly reduces the sliding friction resistance, making the movement of the connector 3 in the Y-axis direction smoother and reducing motion loss. At the same time, the setting of the roller shafts 2152 on both sides plays a precise guiding and limiting role in the sliding direction, effectively preventing deviation. The elastic connection design of the elastic component 2155 can automatically compensate for the gap caused by assembly errors and vibrations, ensuring that the roller shaft 2152 and the guide rail 2151 always maintain close contact, improving the stability and accuracy of the sliding process, thereby ensuring the positioning accuracy of the rotary clamping mechanism 4 in spatial movement, which is conducive to improving the overall assembly quality and efficiency.

[0070] Since the plastic sheet 96 is composed of a sheet body and a clamping post 961, in order to fit the shape of the plastic sheet 96 to form precise positioning and stable clamping, and to avoid the plastic sheet 96 from shifting or being damaged during clamping, a rotary clamping mechanism 4 that matches the shape of the plastic sheet 96 is adopted.

[0071] Specifically, refer to Figure 9 and Figure 10 As shown, the rotating clamping mechanism 4 includes an angle adjustment structure 41, a clamping structure 42, and a mating part 43. The angle adjustment structure 41 is disposed on the connector 3, and the clamping part is the clamping structure 42. The clamping structure 42 is disposed on the angle adjustment structure 41. The clamping structure 42 has two clamping claws for clamping the plastic sheet 96. The number of mating parts 43 is two and they are respectively disposed on the two clamping claws of the clamping structure 42. The opposite sides of the two mating parts 43 are provided with positioning grooves 431 that match the shape of the plastic sheet 96.

[0072] The angle adjustment structure 41 and the clamping structure 42 can be selected as a servo motor and a clamping cylinder, respectively.

[0073] More specifically, the rotary clamping mechanism 4 is mounted on the connector 3 via the angle adjustment structure 41. The two clamping jaws of the clamping structure 42 can rotate in both directions around their own axis under the drive of the angle adjustment structure 41. At the same time, the mating parts 43 on the two clamping jaws achieve precise positioning by fitting the plastic sheet 96 with the positioning grooves 431 of the opposite side of the plastic sheet 96 and the clamping post 961 structure. Then the clamping jaws close to form a stable clamping of the plastic sheet 96. The angle adjustment structure 41 drives the clamped plastic sheet 96 to rotate in the forward direction and tilt to avoid the obstacle point 92 of the product base 91. After the clamping post 961 of the plastic sheet 96 passes through the terminal 93's locking hole 94, the angle adjustment structure 41 rotates in the reverse direction to restore the plastic sheet 96 to a vertical state, completing the clamping and angle adjustment actions in the assembly process.

[0074] The effect of the rotating clamping mechanism 4 is as follows: by precisely matching the shape of the positioning groove 431 with the plastic sheet 96, point-to-point positioning and clamping of the plastic sheet 96 is achieved, effectively avoiding offset and damage during clamping, and ensuring the alignment accuracy of the plastic sheet 96 clamping post 961 and the terminal 93 clamping hole 94; the angle adjustment structure 41 can flexibly realize forward and reverse rotation, perfectly adapting to the assembly requirements of avoiding obstacle point 92. At the same time, the symmetrical clamping design of the two clamping claws further improves the clamping stability. The overall structure takes into account the core requirements of precise positioning, stable clamping and angle adjustment, which not only adapts to the special structure of the plastic sheet 96, but also improves the reliability and accuracy of the assembly process and reduces the assembly defect rate.

[0075] Furthermore, in order to prevent the mating part 43 from excessively clamping the plastic sheet 96, an extension part 7 is provided on the clamping structure 42. A limiting block 8 is provided on the extension part 7, extending to the space between the two clamping claws of the clamping structure 42. The width of the limiting block 8 is consistent with the distance between the two ends of the plastic sheet 96 being clamped. Therefore, it serves to limit the mating part 43 and prevent the plastic sheet 96 from being excessively clamped and damaged.

[0076] Reference Figure 2 and Figure 3 As shown, in order to ensure that the plastic sheet 96 avoids the obstacle point 92 of the product base 91 after tilting, and to ensure that the locking post 961 is smoothly aligned and inserted into the terminal 93 locking hole 94, when the clamping part of the rotating clamping mechanism 4 rotates the plastic sheet 96 to a tilted state, the angle between the locking post 961 of the plastic sheet 96 and the terminal 93 in the tilted state is 45°–75°. This angle range can be flexibly adjusted according to the height, size and position of the obstacle point 92 on the product base 91. A 55° angle is preferred to achieve the best avoidance effect and assembly convenience. Furthermore, when the terminal 93, plastic sheet 96 and obstacle point 92 are different (such as model), the angle range between the locking post 961 of the plastic sheet 96 and the terminal 93 in the tilted state is also different.

[0077] To ensure that the plastic sheet 96 can avoid the obstacle point 92 of the product base 91 after tilting, and to ensure that the locking post 961 is accurately aligned and inserted into the terminal 93 locking hole 94, when the clamping part of the rotating clamping mechanism 4 rotates the plastic sheet 96 to the tilted state, the angle between the locking post 961 of the plastic sheet 96 and the terminal 93 is limited to 45°–75°. This angle can be flexibly adjusted according to the height, size and position of the obstacle point 92 on the product base 91. 55° is preferred to balance the best avoidance effect and ease of assembly.

[0078] The angle between the plastic sheet 96 and the locking post 961 and the terminal 93 is limited to 45°–75°. This ensures that the plastic sheet 96 avoids the obstacle point 92 of the product base 91 when tilted, while also ensuring that the locking post 961 can be smoothly aligned and inserted into the locking hole 94 of the terminal 93. If the angle is too small, the avoidance effect will be insufficient; if the angle is too large, it will easily cause misalignment between the locking post 961 and the locking hole 94, making assembly difficult. This range balances the reliability of avoidance and the convenience of assembly, and is suitable for the obstacle point 92 size and assembly requirements of most special relays 9 and other products.

[0079] At the same time, refer to Figure 11 As shown, considering that the plastic sheet 96 cannot move when it is assembled with the terminal 93 on the product base 91, in order to avoid assembly errors, and considering that the equipment installed in this application (the complete set of equipment for producing relays 9) is usually equipped with a conveying structure for conveying relays 9, such as a slide and push structure, or a belt conveyor mechanism, the above technical solution also includes a mounting frame 5. The mounting frame 5 is provided with a clamping positioner 6. The clamping positioner 6 can be a clamping cylinder. The clamping positioner 6 is used to clamp and position the product to be assembled, the plastic sheet 96.

[0080] Before the plastic sheet 96 is assembled with the terminal 93 of the product base 91, the clamping and positioning device 6 on the mounting bracket 5 clamps and fixes the product to be assembled. By precisely positioning, it limits the displacement of the product during the assembly process, ensuring that the product remains stable throughout the entire process of the rotating clamping mechanism 4 driving the plastic sheet 96 to rotate and avoid the obstacle point 92, and the adjusting mechanism 2 driving the plastic sheet 96 locking post 961 to align and enter the locking hole 94 of the terminal 93. This provides a fixed reference for precise assembly, effectively avoiding the alignment deviation between the plastic sheet 96 locking post 961 and the terminal 93 locking hole 94 caused by the movement of the product during the assembly process, reducing assembly errors, and further improving assembly accuracy and product qualification rate.

[0081] Meanwhile, when the relay 9 is transported using the carrier 10, the carrier 10 can be directly clamped to indirectly clamp and fix the relay 9.

[0082] Furthermore, referring to Figure 11As shown, considering that after the plastic sheet 96 and terminal 93 are assembled, in order to avoid the relay 9 and allow the relay 9 to continue to be conveyed to the next process, the mounting bracket 5 and the clamping positioner 6 are connected by a sliding connection. Of course, in actual use, a linear drive (such as a cylinder) is needed to control the position of the clamping positioner 6 to achieve the effect of avoiding the relay 9.

[0083] In summary, this device, designed for special products with protruding obstacle points 92 (such as special relays 9), overcomes the limitations of traditional assembly. Through the coordination of the adjustment mechanism 2 and the rotatable clamping part, it achieves tilting and precise assembly of the plastic sheet 96, adapting to obstacle avoidance assembly requirements, broadening its applicability, and providing full automation without manual intervention, thus improving assembly efficiency and reducing costs and errors. The adjustment mechanism 2 includes a guide structure and an XYZ three-axis linear module, ensuring precise positioning and movement in three-dimensional space, improving the alignment accuracy of the clamping post 961 and the clamping hole 94, enhancing motion stability, and adapting to various scenarios such as material handling, assembly, and obstacle avoidance. The elastically adjustable sliding component 215 reduces the impact of friction and gaps, further improving positioning accuracy. The rotary clamping mechanism 4 achieves precise and stable clamping of the plastic sheet 96 through the matching positioning groove 431, avoiding displacement and damage. The tilt angle of 45°–75° (preferably 55°) takes into account both avoidance and assembly requirements. The limit block 8 prevents over-clamping. The clamping positioner 6 fixes the product, avoids assembly displacement that causes deviation, and improves the pass rate. Its sliding connection design can avoid the relay 9, adapt to process connection, and significantly improves the overall assembly quality and efficiency, and reduces the defect rate.
