Description

Technical Field

[0001] The present invention relates to the technical field of jigs, and particularly to a quick positioning jig for a handle guard plate in the assembly of an intelligent lock. Background Art

[0002] With the wide application of intelligent door locks, their internal structures are becoming increasingly complex, and the requirements for assembly accuracy are constantly increasing. Among them, the handle guard plate, as an important part of the external structure of the intelligent lock, usually includes a base plate, a front panel and a back panel. Its assembly sequence and positioning accuracy have an important impact on the function and appearance of the whole lock. In automated production, it is necessary to first clamp and position the base plate, then place the front panel above the base plate, then rotate the whole by 180 degrees so that the front panel fits below the base plate, and finally place the back panel on the back of the base plate and fix the three together with screws. This process involves the assembly, flipping and alignment operations of multiple components, and the positioning accuracy and operation stability directly affect the assembly efficiency and product consistency.

[0003] Currently, in the assembly process of intelligent locks, the assembly of the handle guard plate mostly relies on manual operation or general-purpose jigs. Manual positioning has low efficiency and large errors, which not only increases the assembly difficulty, but also is difficult to meet the dual requirements of speed and accuracy in mass production. And general jigs have problems such as poor adaptability and frequent repeated adjustment when dealing with changes in the guard plate structure. Especially in the process of flipping and assembling the base plate and the front panel, misalignment or detachment is likely to occur, affecting the subsequent assembly stability. In view of the high-efficiency and precise positioning requirements of such precision components on the automated assembly line, there is still much room for improvement in the existing assembly means and equipment. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, a quick positioning jig for a handle guard plate in the assembly of an intelligent lock is provided. By designing two clamping plates that can move towards each other in a flipping frame and arranging end positioning components that contact the ends of the short sides of the base plate between the two ends of the two clamping plates, after the base plate is placed on the bracket, the sides of the base plate can be quickly and accurately abutted and positioned; at the same time, when the front panel is placed on the handle guard plate, the auxiliary jig installed on the clamping plate can effectively initially fix the front panel, and during the process of flipping the base plate, it can effectively prevent the front panel from falling off the base plate, thus solving the problem that the front panel is likely to fall off when the existing jig assembles the handle guard plate.

[0005] In order to solve the problems of the prior art, the present invention provides a quick positioning fixture for a handle guard plate for assembling an intelligent lock, which is used to fix a panel in the handle guard plate while fixing a substrate in the handle guard plate. It includes a flip frame and a motor for driving the flip frame to rotate, wherein two clamps that can move toward each other are provided in the flip frame, and the same end of the two clamps is provided with an end positioning component that can move along its length direction, and when the two clamps clamp the long side of the substrate toward each other, the end positioning component abuts against the short side of the substrate; a bracket that can move downward is provided at the bottom of the flip frame, and when the flip frame moves downward, the bracket moves downward, and the top and bottom ends of the clamp are provided with auxiliary clamps that can abut against the side of the substrate along the width direction of the clamp; the auxiliary clamp includes a clamp seat connected to the clamp plate and a clamp block elastically connected to the clamp seat, the clamp block having an upper inclined surface and a lower inclined surface at one end facing away from the clamp seat, and after the lower edge of the substrate moves from top to bottom and abuts on the upper inclined surface, the clamp block overcomes the elastic force and moves until the lower inclined surface of the clamp block abuts against the upper edge of the substrate.

[0006] Preferably, the flip frame is provided with two drive plates capable of moving toward each other and a clamping driver for driving the two drive plates to move toward each other, the clamping plate is located between the two drive plates, and an elastic connection component is provided between the drive plate and its adjacent clamping plate.

[0007] Preferably, the elastic connecting assembly includes a connecting rod and a connecting spring, the connecting rods are equidistantly arranged on the side of the clamping plate facing the driving plate, the connecting rods extend along the width direction of the clamping plate and slide through the driving plate, and a limiting ring is provided at one end of the connecting rod passing through the driving plate; the connecting spring is sleeved on the connecting rod, and the connecting spring is located between the driving plate and the clamping plate.

[0008] Preferably, the clamping drive includes a sliding plate, a swing arm, a linear drive and a driving arm. The sliding plate is slidably arranged on the driving plate along the length direction of the driving plate. There are two swing arms, which are arranged in parallel between the inner side of the flip frame and the sliding plate. The two ends of the swing arm are respectively rotatably connected to the inner side of the flip frame and the sliding plate. The linear drive is arranged in the flip frame and has an output rod. The two ends of the driving arm are respectively rotatably connected to one of the swing arms and the output rod.

[0009] Preferably, the bracket includes a lifting plate elastically arranged at the bottom of the flip frame along the longitudinal direction, and the top of the lifting plate is provided with support plates arranged at equal intervals along the length direction of the clamp, and both sides of the support plates have inclined surfaces, and the top of the support plate abuts against the bottom end of the clamp, and the bottom edge of the flip frame abuts on the inclined surface of the support plate to flip.

[0010] Preferably, the positioning fixture further includes a bottom plate, the flipping frame is rotatably arranged on the top of the bottom plate, a positioning post is arranged at the bottom end of the lifting plate and slides downward through the bottom plate, and an elastic abutting element is sleeved on the positioning post, and the elastic abutting element is located between the bottom plate and the lifting plate.

[0012] Preferably, a pressure seat capable of moving along the length direction of the clamping plate is further arranged at the end of the abutting seat, and an elastic buffer element is arranged between the pressure seat and the abutting seat.

[0013] The beneficial effects of this application compared with the prior art are as follows: In this application, by designing two clamping plates that can move towards each other in the flipping frame and arranging an end positioning assembly with an abutting function between the two ends of the two clamping plates, the end positioning assembly can be in close contact with the short side surface of the substrate, so as to ensure that after the substrate is placed on the bracket, the side surface of the substrate can be accurately abutted and positioned quickly and stably. Specifically, after the substrate is placed on the bracket, the combined action of the two clamping plates and the end positioning assembly enables the substrate to maintain a fixed positioning state. At the same time, when the panel is placed on the handle guard plate, the auxiliary fixture installed on the clamping plate can effectively initially fix the panel and prevent the panel from loosening and slipping. This design not only ensures the stability of the panel during the process of flipping the substrate, but also prevents the panel from detaching from the handle guard plate, thus solving the problem that the panel is prone to falling off during the assembly process of the traditional fixture. Through this optimization, not only the work efficiency is improved, the assembly accuracy is enhanced, but also the reliability and safety of the system are enhanced, and the overall performance of the intelligent lock assembly process is further improved.

Detailed implementation manners

[0025] In order to further understand the features, technical means, and the specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0026] As shown in Figure 1 , Figure 2 , Figure 5 , Figure 8 and Figure 9As shown, a quick positioning fixture for a handle guard plate for assembling a smart lock is used to fix the base plate 81 in the handle guard plate while fixing the panel 82 in the handle guard plate. It includes a flip frame 1 and a motor 2 for driving the flip frame 1 to rotate. The flip frame 1 is provided with two clamps 3 that can move toward each other, and the same end of the two clamps 3 is provided with an end positioning component 4 that can move along its length direction. When the two clamps 3 clamp the long side of the base plate 81 towards each other, the end positioning component 4 abuts against the short side of the base plate 81; the bottom of the flip frame 1 is provided with a bracket 5 that can move downward, and when the flip frame 1 moves downward, the bracket 5 moves downward, and the top and bottom ends of the clamps 3 are provided with auxiliary clamps 6 that can abut against the side of the panel 82 along the width direction of the clamps 3.

[0027] When the two clamps 3 clamp the long side of the substrate 81 towards each other, the end positioning assembly 4 is precisely abutted against the short side of the substrate 81 to ensure the stable positioning of the substrate 81. The bottom of the flip frame 1 is provided with a bracket 5 that can move downward. When the flip frame 1 moves downward, the bracket 5 moves downward synchronously, so that the substrate 81 can be supported when placed between the two clamps 3. At the same time, the top and bottom ends of the clamps 3 are provided with auxiliary clamps 6, which can move along the width direction of the clamps 3 and precisely abut against the side of the panel 82 to effectively fix the panel 82. This design can not only ensure that the panel 82 will not fall off the substrate 81 when the substrate 81 is flipped, but also improve the stability and efficiency of the entire assembly process. Through this structural improvement, the risk of the panel 82 falling off in the traditional assembly process is significantly reduced, the assembly accuracy and operation convenience of the smart lock are improved, and it has higher applicability and reliability.

[0028] like Figure 3 and Figure 4 As shown, the auxiliary clamp 6 includes a clamp seat 61 connected to the clamp plate 3 and a clamp block 62 elastically connected to the clamp seat 61, and the end of the clamp block 62 away from the clamp seat 61 has an upper inclined surface 621 and a lower inclined surface 622. After the lower edge of the panel 82 moves from top to bottom and abuts against the upper inclined surface 621, the clamp block 62 overcomes the elastic force and moves until the lower inclined surface 622 of the clamp block 62 abuts against the upper edge of the panel 82.

[0029] The auxiliary clamp 6 includes a clamp seat 61 connected to the clamp plate 3 and a clamp block 62 elastically connected to the clamp seat 61. The structure of the clamp block 62 is designed to be provided with an upper inclined surface 621 and a lower inclined surface 622 at one end away from the clamp seat 61. When the lower edge of the panel 82 moves from top to bottom, it first contacts the upper inclined surface 621, thereby guiding the accurate positioning of the panel 82. At this time, the clamp block 62 overcomes the external force through its elastic characteristics and moves slowly until the lower inclined surface 622 accurately abuts against the upper edge of the panel 82. As the lower inclined surface 622 of the clamp block 62 contacts the upper edge of the panel 82, the panel 82 is firmly clamped between the clamp plate 3 and the clamp block 62, thereby preventing the panel 82 from sliding or loosening.

[0030] This design optimizes the adaptive ability of the clamp, ensuring that the panel 82 can be smoothly and firmly fixed on the base plate 81 under the action of the clamp. The elastic connection allows the clamp block 62 to be fine-tuned according to the different thicknesses of the panel 82, thereby providing more flexible adaptability and avoiding the problem of loosening of the panel 82 due to improper installation. In addition, the inclined design of the clamp block 62 makes the fixing process of the panel 82 smoother, reduces friction and damage during operation, and improves assembly efficiency and assembly quality.

[0031] like Figure 7 As shown, the clamping plate 3 is provided with threaded holes 31 arranged at equal intervals along its length direction, and the clamping seat 61 is provided with bolts 611 passing through it. The bolts 611 pass through the clamping seat 61 and are threadedly connected with the threaded holes 31.

[0032] By adjusting the screw bolts 611 and threadedly connecting them with the threaded holes 31 at different positions, the position of the clamp seat 61 on the base plate 81 can be precisely adjusted, so that the initial position of the clamp block 62 on the clamp plate 3 can be flexibly adjusted according to the actual assembly requirements. This design provides a high degree of adjustability and adaptability, which can meet the requirements of different assembly tasks and ensure that the clamp always maintains the best working state under a variety of different working conditions.

[0033] Specifically, the threaded holes 31 on the clamp 3 are arranged at equal intervals to ensure that they can provide an accurate and uniform adjustment range during the use of the clamp. Through the connection of the bolts 611 with different threaded holes 31, the operator can quickly adjust the specific position of the clamp seat 61 without disassembling or resetting the clamp. This adjustment method greatly improves the assembly flexibility, allowing the clamp block 62 to be accurately aligned to the predetermined position of the panel 82 or other workpieces according to actual needs. Whether increasing the spacing of the clamp seat 61 to accommodate a thicker panel 82, or reducing the spacing to accommodate a thinner material, the operation process can be completed quickly and efficiently, thereby reducing adjustment time and labor costs.

[0034] like Figure 6As shown, two driving plates 11 capable of moving towards each other and a clamping driver for driving the two driving plates 11 to move towards each other are provided in the flipping frame 1. The clamping plate 3 is located between the two driving plates 11, and an elastic connection assembly is provided between the driving plate 11 and the adjacent clamping plate 3.

[0035] In the flipping frame 1, two driving plates 11 capable of moving towards each other are designed, and a clamping driver dedicated to driving these two driving plates 11 to move towards each other is equipped. This driver drives the two driving plates 11 to move synchronously or independently along a specific track or direction, thereby adjusting the position of the clamping plate 3. The clamping plate 3 is located between the two driving plates 11 to ensure a stable and uniform clamping effect during the operation of the flipping frame 1.

[0036] To improve the adaptability and operation accuracy of the system, an elastic connection assembly is provided between the driving plate 11 and the adjacent clamping plate 3. These elastic components can be springs, airbags or other types of elastic materials, which can automatically adjust the stress state and position of the clamping plate 3 during the movement of the driving plate 11. This elastic connection assembly provides a necessary buffering effect between the clamping plate 3 and the driving plate 11, preventing damage to the clamping plate 3 or the driving plate 11 caused by the impact of excessive force. Especially in the case of high-speed operation or large load fluctuations, it can effectively reduce the wear of the system and improve the service life.

[0037] Specifically, the elastic connection assembly not only ensures that the relative movement between the driving plate 11 and the clamping plate 3 is smoother and more stable, but also enables the clamping plate 3 to fit more precisely to the surface of the target workpiece during the flipping process, providing a uniform clamping force. In addition, the presence of the elastic components enables the system to maintain a stable clamping effect in the face of small changes in the size or shape of the workpiece, further enhancing the tolerance adaptation ability during the assembly process.

[0038] As Figure 6 shown, the elastic connection assembly includes a connecting rod 131 and a connecting spring 132. The connecting rods 131 are equidistantly arranged on the side of the clamping plate 3 facing the driving plate 11. The connecting rods 131 extend along the width direction of the clamping plate 3 and slide through the driving plate 11. A limit ring 133 is provided at one end of the connecting rod 131 passing through the driving plate 11; the connecting spring 132 is sleeved on the connecting rod 131, and the connecting spring 132 is located between the driving plate 11 and the clamping plate 3.

[0039] The connecting rods 131 are equidistantly arranged on the side of the clamping plate 3 facing the driving plate 11. These connecting rods 131 extend along the width direction of the clamping plate 3 and slide through the driving plate 11.

[0040] A limiting ring 133 is provided at one end of each connecting rod 131 passing through the driving plate 11. The function of the limiting ring 133 is to prevent the connecting rod 131 from falling off or shifting during the sliding process, ensuring that the connecting rod 131 always maintains a stable positioning state. Through mechanical clamping or elastic fitting, the limiting ring 133 can effectively limit the movement range of the connecting rod 131 and prevent it from exceeding the predetermined sliding interval.

[0041] The connecting spring 132 is sleeved on the connecting rod 131 and is located between the driving plate 11 and the clamping plate 3. The main function of the connecting spring 132 is to provide an elastic restoring force. When the clamping plate 3 and the driving plate 11 undergo relative displacement, the connecting spring 132 adjusts its elastic force by compression or stretching to ensure that the clamping plate 3 can quickly return to the optimal clamping position after the driving plate 11 moves. This elastic connection not only provides the necessary buffering effect and reduces the damage to the system caused by external impact forces, but also enables precise cooperation between the clamping plate 3 and the driving plate 11 through the elastic adjustment of the spring.

[0042] As Figure 8 and Figure 9 shown, the clamping driver includes a sliding plate 121, a swing arm 122, a linear driver 123, and a driving arm 124. The sliding plate 121 is slidably arranged on the driving plate 11 along the length direction of the driving plate 11. There are two swing arms 122, and the two swing arms 122 are arranged in parallel between the inner side of the flipping frame 1 and the sliding plate 121. The two ends of the swing arm 122 are respectively rotatably connected to the inner side of the flipping frame 1 and the sliding plate 121. The linear driver 123 is arranged in the flipping frame 1 and has an output rod. The two ends of the driving arm 124 are respectively rotatably connected to one of the swing arms 122 and the output rod.

[0043] When the linear driver 123 is started, its output rod drives one end of the swing arm 122 to slide through the driving arm 124, thereby causing the swing arm 122 to swing inside the flipping frame 1 around its rotation connection point. This movement is transmitted to the driving plate 11 through the sliding plate 121 connected to the swing arm 122, causing the sliding plate 121 to slide smoothly along the length direction of the driving plate 11. The sliding plate 121 moves freely in the flipping frame 1, thereby driving the clamping plate 3 to precisely clamp the substrate 81 and realizing an efficient and stable clamping operation. To ensure the smoothness of the sliding process, a sliding connection structure is adopted between the sliding plate 121 and the driving plate 11 to reduce friction and movement errors.

[0044] The design of the clamping drive consists of a sliding plate 121, a swing arm 122, a linear drive 123 and a driving arm 124, and the system has high flexibility and precision. The two swing arms 122 are arranged in parallel between the inner side of the flip frame 1 and the sliding plate 121, and are rotatably connected to the inner side of the flip frame 1 and the sliding plate 121 respectively. The linear drive 123 is connected to the driving arm 124 through an output rod, and the two ends of the driving arm 124 are rotatably connected to the swing arm 122 and the output rod respectively, ensuring a smooth and efficient driving process. This design not only realizes precise clamping adjustment, but also can adjust the clamping force and position according to actual needs, thereby improving the flexibility and efficiency of the automated production line.

[0045] like Figure 3 As shown, the bracket 5 includes a lifting plate 51 elastically arranged at the bottom of the flip frame 1 along the longitudinal direction, and the top of the lifting plate 51 is provided with a support plate 52 arranged at equal intervals along the length direction of the clamp plate 3, and both sides of the support plate 52 have inclined surfaces. The top of the support plate 52 abuts against the bottom end of the clamp plate 3, and the bottom edge of the flip frame 1 abuts on the inclined surface of the support plate 52 to flip.

[0046] The bracket 5 includes a lifting plate 51 elastically arranged at the bottom of the flip frame 1 in the longitudinal direction. A plurality of support plates 52 are evenly arranged at the top of the lifting plate 51, and these support plates 52 are arranged at equal intervals along the length direction of the clamping plate 3 to ensure that the clamping plate 3 can be firmly supported and clamped. Each support plate 52 is provided with inclined surfaces on both sides, and these inclined surfaces play a role of guidance and support. When the top of the support plate 52 is in close contact with the bottom end of the clamping plate 3, a stable supporting force is provided to ensure that the clamping plate 3 maintains accurate positioning during the flipping process. When the flip frame 1 is flipped, after the edge of the bottom end of the flip frame 1 contacts the inclined surface of the support plate 52, the support plate 52 overcomes the elastic force and moves downward through appropriate force transmission, and after the flip frame 1 is flipped 180 degrees, the support plate 52 is re-contacted at the bottom end of the flip frame 1 under the action of the elastic force to prevent the fixed substrate 81 from escaping from the clamping of the clamping plate 3.

[0047] like Figure 3 As shown, the positioning fixture also includes a base plate 7, the flip frame 1 is rotatably set on the top of the base plate 7, and the bottom end of the lifting plate 51 is provided with a positioning column 53 that slides downward and penetrates the base plate 7. The positioning column 53 is sleeved with an elastic abutment element 54, and the elastic abutment element 54 is located between the base plate 7 and the lifting plate 51.

[0048] The positioning fixture further includes a base plate 7. The flipping frame 1 is arranged on the top of the base plate 7 in a rotatable connection manner, allowing the flipping frame 1 to maintain smooth movement during rotation. The bottom end of the lifting plate 51 is equipped with a positioning post 53 that slides downward and penetrates the base plate 7. The positioning post 53 provides effective guidance and support between the lifting plate 51 and the base plate 7. An elastic abutting element 54 sleeved on the positioning post 53 further enhances the stability of the fixture. These elastic elements ensure the precise adjustment of the lifting plate 51 during operation and provide additional buffering force when the flipping frame 1 rotates, avoiding the impact caused by violent movement. At the same time, during the rotation of the flipping frame 1, it is ensured that the supporting plate 52 always keeps in close contact with the bottom end of the flipping frame 1, thereby stably supporting the substrate 81. After the flipping frame 1 rotates to 180 degrees, the supporting plate 52 can accurately re-lift the substrate 81, preventing the substrate 81 from detaching due to the flipping action. The stability and safety during this process are greatly guaranteed, ensuring that the substrate 81 is always in a reliable clamping state and avoiding potential misoperation or damage risks.

[0049] As Figure 6 shown, the end positioning assembly 4 includes an abutting seat 41 and a transmission connecting rod 42. The abutting seat 41 is slidably arranged between the two clamping plates 3 along the length direction of the clamping plate 3. There are two transmission connecting rods 42, and the end parts of the two transmission connecting rods 42 are respectively rotatably connected to the end part of the clamping plate 3 and the abutting seat 41.

[0050] When the two substrates 81 move towards each other, the transmission connecting rod 42 ensures that the abutting seat 41 can stably and accurately contact the short side surface of the substrate 81, thereby realizing the precise positioning of the substrate 81. Through the transmission connecting rod 42 rotatably connected to the substrate 81, the movement can be effectively transmitted to the abutting seat 41, ensuring the stability and accuracy of the substrate 81 during the clamping process.

[0051] The abutting seat 41 slides along the length direction of the clamping plate 3 and is arranged between the two clamping plates 3, ensuring that it can freely adjust following the movement change of the clamping plate 3. There are two transmission connecting rods 42, which are respectively connected to the end part of the clamping plate 3 and the abutting seat 41 through rotational connections. This structural design enables the transmission connecting rod 42 to act on the abutting seat 41 synchronously when the clamping plate 3 moves, precisely controlling its movement trajectory and ensuring that each clamping operation can accurately position the substrate 81.

[0052] As Figure 6 shown, a pressure seat 43 capable of moving along the length direction of the clamping plate 3 is further arranged at the end part of the abutting seat 41, and an elastic buffer element 44 is arranged between the pressure seat 43 and the abutting seat 41.

[0053] In order to ensure that the rigid force does not scratch or deform the base plate 81 during operation, the end of the abutment seat 41 is equipped with a pressure seat 43 that can move along the length direction of the clamping plate 3. The pressure seat 43 and the abutment seat 41 are connected by an elastic buffer element 44, so that the pressure seat 43 can accurately abut the short side of the base plate 81 in an elastic manner to avoid damage caused by hard contact.

[0054] The role of the elastic buffer element 44 is not only to absorb and reduce the impact of external forces, but also to make appropriate adjustments according to the slight position changes of the substrate 81, ensuring that the pressure seat 43 does not apply too much or too little force when contacting the substrate 81. The elastic design provides a flexible abutment method for the pressure seat 43, thereby avoiding the problems that may be caused by rigid connection, such as scratches or deformation of the surface of the substrate 81. Especially when handling delicate or fragile substrates 81, this elastic design provides additional protection.

[0055] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
