[0027] In this embodiment, the assembly device of the terminal 93 and the plastic sheet 96 is given, which comprises a support 1, a connecting piece 3, and a rotating clamping mechanism 4. Figures 1-11 The assembly device of the terminal 93 and the plastic sheet 96 is given, which comprises a support 1, a connecting piece 3, and a rotating clamping mechanism 4.

[0028] The present application is mainly used for products that need to be avoided assembly, such as relays 9, and the following examples are all based on relays 9. In some special relays 9, there is a protrusion on the base 91 of the relay 9, that is, the obstacle point 92. The traditional assembly method is to directly assemble the clamping column 961 of the plastic sheet 96 in the terminal 93 clamping hole 94 on the base 91, but in some special relays 9, due to the existence of the obstacle point 92, it is impossible to assemble. Therefore, the present application adopts the method of rotating the plastic sheet 96 to avoid the obstacle point 92 on the base 91 of the relay 9, and then uses the linear displacement method to assemble the clamping column 961 of the plastic sheet 96 in the terminal 93 clamping hole 94 on the base 91. The specific method is as follows: The support 1 is composed of a chassis and a support plate mounted on the chassis, mainly bearing the support of the main part of the device, and the support plate of the support 1 is provided with a positioning mechanism 2. The positioning mechanism 2 adopts a screw transmission screw and a sliding block to realize the adjustment of the position of the connected components, such as a linear slide, and of course, it can also adopt an electric push rod and a cylinder structure. Its function is to adjust the space position of the connected parts and the plastic sheet 96.

[0029] The connecting piece 3 is installed on the positioning mechanism 2, which is used to connect the rotating clamping mechanism 4. Because the moving end of the positioning mechanism 2 is away from the relay 9 by a certain height difference, the rotating clamping mechanism 4 cannot be directly connected with the base 91 of the relay 9. Therefore, the connecting piece 3 is adopted, and the positioning mechanism 2 adjusts the space position of the rotating clamping mechanism 4 and the plastic sheet 96 clamped by the rotating clamping mechanism 4 by driving the connecting piece 3 to move.

[0030] The rotating clamping mechanism 4 is installed on the connecting piece 3, and the rotating clamping mechanism 4 is an output end of the device and is composed of two structures of a rotating function and a clamping function. Specifically, the rotating clamping mechanism 4 has a clamping part for clamping the plastic sheet 96, and the clamping part can also rotate in a forward and reverse direction around its own axis.

[0031] The adjusting mechanism 2 drives the connecting piece 3 and the rotating clamping mechanism 4 to move, so that the clamping column 961 of the plastic sheet 96 approaches the clamping hole 94 of the terminal 93, the clamping part of the rotating clamping mechanism 4 is synchronously rotated in a forward direction to an inclined state, as shown in Figure 2 , avoids the obstacle point 92 on the product base 91, and makes the clamping column 961 of the plastic sheet 96 pass through the clamping hole 94 of the terminal 93, and the rotating clamping mechanism 4 is reversely rotated to a vertical state, as shown in Figure 3 , and the end of the plastic sheet 96 away from the clamping column 961 is embedded in the clamping hole 95 of the product base 91.

[0032] More specifically, the clamping part of the rotating clamping mechanism 4 first clamps the plastic sheet 96, the adjusting mechanism 2 drives the connecting piece 3 installed thereon to move, and then drives the rotating clamping mechanism 4 connected with the connecting piece 3 to move along a predetermined path, so that the clamping column 961 of the plastic sheet 96 gradually approaches the clamping hole 94 of the terminal 93 of the relay 9. In this process, the clamping part of the rotating clamping mechanism 4 is synchronously rotated in a forward direction, so that the plastic sheet 96 is in an inclined state to avoid the raised obstacle point 92 on the product base 91, and ensure that the clamping column 961 of the plastic sheet 96 smoothly passes through the clamping hole 94 of the terminal 93. After the clamping column 961 is in place, the clamping part of the rotating clamping mechanism 4 is reversely rotated to restore to a vertical state, drives the end of the plastic sheet 96 away from the clamping column 961 to be accurately embedded in the clamping hole 95 of the product base 91, and completes the assembly of the plastic sheet 96 and the terminal 93.

[0033] In summary, for special products with raised obstacle points 92, such as special relays 9, the traditional linear displacement assembly method is broken through due to the limitation that the obstacle point 92 cannot be assembled. Through the cooperation of the adjusting mechanism 2 and the clamping part that can rotate in a forward and reverse direction, the inclined avoidance and accurate assembly of the plastic sheet 96 are realized, which not only ensures the smoothness of the assembly process, but also improves the accuracy of the assembly position, effectively adapts to the product demand that needs to avoid assembly, widens the application range of the assembly device, and at the same time, the entire assembly process does not need manual intervention to avoid the obstacle point 92, improves the assembly efficiency and automation degree, and reduces the labor operation cost and assembly error.

[0034] In order to improve the assembly precision of the plastic sheet 96 and the terminal 93, and ensure that the clamping column 961 of the plastic sheet 96 is accurately aligned with the clamping hole 94 of the terminal 93, the adjusting mechanism 2 with a guide structure is adopted.

[0035] Specifically, referring to Figure 5As shown, the positioning mechanism 2 comprises a positioning assembly 21 and a guide 22; The positioning assembly 21 and the guide 22 are both mounted on the support plate of the support 1, the guide 22 is connected with the positioning assembly 21, the positioning assembly 21 is also connected with the connecting piece 3, the guide 22 is used for guiding and supporting the connecting piece 3 driven by the positioning assembly 21, and the guiding direction is along the center axis direction of the clamping hole 94 of the terminal 93; the positioning assembly 21 is used for driving the connecting piece 3 to move close to or away from the clamping hole 94 of the terminal 93.

[0036] The guide 22 is composed of a sliding rail and a sliding block, the sliding rail is directly mounted on the support plate of the support 1, and the length direction is along the center axis direction of the clamping hole 94 of the terminal 93, that is, the direction of the straight movement and assembly of the clamping column 961 of the plastic sheet 96 to the clamping hole 94 of the terminal 93, and the sliding block is slidingly mounted on the sliding rail and connected with the positioning assembly 21.

[0037] The positioning mechanism 2 provides driving force through the positioning assembly 21, drives the connecting piece 3 connected therewith to move close to or away from the clamping hole 94 along the center axis direction of the clamping hole 94 of the terminal 93, and the guide 22 guides and supports the movement of the connecting piece 3, and the guiding direction is the same as the direction of the center axis of the clamping hole 94 of the terminal 93, which ensures the accurate movement of the connecting piece 3, the subsequent rotary clamping mechanism 4 and the plastic sheet 96, and the clamping column 961 of the plastic sheet 96 can accurately align with the clamping hole 94 of the terminal 93, laying a precise position foundation for the subsequent rotary avoidance assembly.

[0038] Through the cooperation of the positioning assembly 21 and the guide 22, the alignment accuracy of the clamping column 961 of the plastic sheet 96 and the clamping hole 94 of the terminal 93 is effectively improved, the assembly failure caused by movement deviation is avoided, the support effect of the guide 22 enhances the stability of the positioning process, reduces the influence of vibration on the assembly accuracy, and the structure is simple and accurate in guiding, which can adapt to scenes requiring high-precision assembly, improve the overall assembly quality and efficiency, and reduce the defective product rate.

[0039] Reference Figure 5As shown, the rotary clamping mechanism 4 needs to be moved to a predetermined position for picking operation before assembling the plastic sheet 96 to the terminal 93, and the positioning mechanism 2 is preferably an XYZ three-axis linear module, because the XYZ three-axis linear module can realize the position adjustment of the connecting piece 3 and the rotary clamping mechanism 4 in the X direction, the Y direction and the Z direction, wherein the X direction and the Y direction correspond to the length and the width of the table on which the relay 9 is placed, and the Z direction is the height direction perpendicular to the table. As long as the direction of one axis is the same as the direction of the center axis of the clamping hole 94 of the terminal 93, that is, the direction of the linear movement and assembly of the plastic sheet 96 clamping column 961 to the clamping hole 94 of the terminal 93, and the movement in the other two directions (and the three directions are perpendicular to each other), the rotary clamping mechanism 4 can be moved in any position in space. Not only can it meet the demand of linearly moving the rotary clamping mechanism 4 to assemble the plastic sheet 96 to the terminal 93, but also can position the rotary clamping mechanism 4 to a specific position for picking. At the same time, considering that the device is only a certain process in the production of the relay 9, the assembled and semi-finished relay 9 needs to be continuously conveyed to the next process, and the relay 9 with the assembled plastic sheet 96 cannot block the relay 9 in space. Before the relay 9 with the assembled plastic sheet 96 is continuously conveyed to the next process, the rotary clamping mechanism 4 can be controlled to avoid the relay 9 in the height direction.

[0040] Based on the foregoing, the guide 22 only limits the movement of the rotary clamping mechanism 4 in the direction of the linear movement and assembly of the plastic sheet 96 clamping column 961 to the clamping hole 94 of the terminal 93 (the direction of the center axis of the clamping hole 94), but the movement of the rotary clamping mechanism 4 in the other two directions is not guided. In order to further improve the accuracy and stability of the rotary clamping mechanism 4 in the other two directions, an XYZ three-axis linear module is adopted which guides in the other two directions.

[0041] Specifically, referring 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.

[0042] The X linear module 212 is arranged on the support plate of the support 1, the length direction of the X linear module 212 is parallel to the guiding direction of the guide 22, and the direction of the X linear module 212 adjusting the position of the rotary clamping mechanism 4 corresponds to the direction of the linear movement and assembly of the plastic sheet 96 clamping column 961 to the clamping hole 94 of the terminal 93 (the direction of the center axis of the clamping hole 94). Figure 5 That is, the X-axis direction in the middle of the X linear module 212, that is, the direction of the center axis of the clamping hole 94).

[0043] And, in order to facilitate the installation of Y moving module 213 and Z moving module 214, the moving frame 211 is vertically arranged on the X linear module 212, the slider on the guide 22 is also connected with the moving frame 211, the slide rail of the guide 22 and the slider cooperate with each other to limit the moving frame 211, at the same time, when the X linear module 212 drives the moving frame 211 to move, the direction is more accurate, and the X linear module 212 also shares the weight of the moving frame 211 and the components connected with the moving frame 211.

[0044] Y moving module 213 and Z moving module 214 are arranged on the moving frame 211, and 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, wherein the direction of the Y moving module 213 adjusting the position of the rotary clamping mechanism 4 is perpendicular to the direction of the plastic sheet 96 clamping column 961 moving linearly and assembling the terminal 93 clamping hole 94 (in the X axis direction), and the direction of the Z moving module 214 adjusting the position of the rotary clamping mechanism 4 is perpendicular to the plane composed of the direction of the plastic sheet 96 clamping column 961 moving linearly and assembling the terminal 93 clamping hole 94 (in the X axis direction) and the direction of the Y moving module 213 adjusting the position of the rotary clamping mechanism 4 (in the Y axis direction). Figure 5 Figure 5 Figure 5 Figure 5 Figure 5

[0045] And, in order to avoid the Y moving module 213 and the Z moving module 214 from being hindered when one of them adjusts the position of the rotary clamping mechanism 4, the Y moving module 213 is slidingly connected with the connecting piece 3, and the sliding direction of the connecting piece 3 relative to the Y moving module 213 is the same as the length direction of the Z moving module 214, one end of the connecting piece 3 away from the rotary clamping mechanism 4 is slidingly connected with the Z moving module 214 through the sliding piece 215, and the sliding direction of the connecting piece 3 relative to the Z moving module 214 is the same as the length direction of the Y moving module 213, which makes that when any one of the Y moving module 213 and the Z moving module 214 drives the rotary clamping mechanism 4 to move through the connecting piece 3, the connecting piece 3 is slidingly connected with the other module, and the sliding direction is consistent with the moving direction, so that the movement is not hindered.

[0046] The XYZ three-axis linear module cooperates with the X, Y and Z linear modules to realize the accurate positioning and movement of the rotary clamping mechanism 4 in the three-dimensional space. The X linear module 212 moves along the guide direction of the guide 22 (corresponding to the assembling direction of the plastic sheet 96 clamping column 961, that is, the X axis direction), Figure 7 ​​​​​The 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.

[0047] 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.

[0048] 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.

[0049] Specifically, refer to Figure 8 and Figure 6 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.

[0050] 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 9 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.

[0051] 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.

[0052] 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.

[0053] Specifically, refer to Figure 10 and Figure 2 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.

[0054] The angle adjustment structure 41 and the clamping structure 42 can be selected as a servo motor and a clamping cylinder, respectively.

[0055] 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.

[0056] 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.

[0057] 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 plays the role of limiting the mating part 43 and preventing the plastic sheet 96 from being excessively clamped and damaged.

[0058] Reference Figure 3 and Figure 11 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Furthermore, referring to ​As 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 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.

[0065] 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.
