[0033] 1. In the contactor production line provided by the present invention, the base component assembly line, the intermediate assembly line, and the base component assembly line are arranged on the feeding assembly table along the U-shaped interval contour shape. The contactor product is divided into a base semi-finished component and a base semi-finished component by the base component assembly line and the base component assembly line for synchronous assembly. The base semi-finished component and the base semi-finished component are bidirectionally transported to the intermediate assembly line through the U-shaped flow channel structure, and then the base semi-finished component and the base semi-finished component are assembled to form a contactor finished product through the intermediate assembly line. The advantage of such a design is that the base component assembly line and the base component assembly line independently complete the assembly of their respective parts, and finally the intermediate assembly line completes the assembly, which can reduce the waiting time of the assembly process, improve the overall assembly progress, and shorten the time to complete the assembly of a product.

[0035] 3. In the contactor production line provided by the present invention, when assembling the base and the arc extinguishing parts, the multiple arc extinguishing parts are first sleeved on the raised end of the elastic riveting platform, and then the base is installed on the elastic riveting platform, so that the multiple arc extinguishing grooves of the base are just opposite to the arc extinguishing parts up and down, and the elastic riveting platform is applied with pressure by driving the pressure block downward to press the base. During the downward pressing process of the elastic riveting platform, the push rod passes through the hollow groove to push the arc extinguishing parts, and the multiple arc extinguishing parts are synchronously inserted into the arc extinguishing grooves of the base. After the driving pressure block moves upward, the elastic riveting platform will automatically reset to the initial position elastically, which is convenient for the next riveting operation of the arc extinguishing parts. With this structural arrangement, multiple arc extinguishing parts can be riveted and installed at one time through the riveting arc extinguishing part device. The operation is simple and convenient, and it saves time and effort. The assembly accuracy is high, and there is no collision damage to the base, and the assembly efficiency is high.

[0036] 4. In the contactor production line provided by the present invention, a plurality of contacts are correspondingly assembled into a plurality of contact slots at both ends of the base through a contact assembly device. During assembly, the base is first positioned and installed in the positioning slot of the base platform, and then the driving cylinder drives the two driving blocks to move toward each other and clamp the base. According to the plurality of contact guide slots corresponding to the plurality of contact slots on the base provided on the driving block, the push rod component moves along the contact guide slots toward one side of the base to push the contacts on the contact guide slots into the contact slots of the base accordingly, thereby assembling the contacts onto the base to form a base component assembly. Finally, the base component assembly is removed from the contact assembly device and continues to be conveyed along the flow channel structure to the intermediate assembly line for final assembly, thereby ensuring the connection and coordination between the upper and lower processes. The operation is simple, convenient, time-saving and labor-saving, and a plurality of contacts can be synchronously loaded into the contact slots at both ends of the base in one step, thereby ensuring the synchronization and safety of the pushed contacts, with high assembly accuracy and improved assembly efficiency.

[0037] 5. In the contactor production line provided by the present invention, the two adjusting rods on the limit baffle are rotated to move the adjusting rods closer to or away from the side wall of one side of the base, and the position distance of the base from the left and right sides of the positioning groove can be adjusted by the adjusting rods, that is, when the base is installed into the positioning groove, and the side wall of one side of the base is abutted against the two adjusting rods, the installation position of the base is calibrated at this time, thereby ensuring that the multiple contact grooves on the base correspond to the multiple contact guide grooves on the driving block one by one, which has the effect of positioning and calibrating the base in the positioning groove, and the installation is convenient and quick, and the installation accuracy is high.

[0055] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] Example 1

[0057] The present embodiment is described in detail below with reference to the accompanying drawings:

[0058] This embodiment provides Figure 1-11A contactor production line shown includes:

[0059] The feeding assembly platform 1 is arranged in a U-shaped structure, and a U-shaped section 11 is formed inside thereof;

[0060] The base component assembly line 2 is arranged on one side of the feeding assembly table 1, and is used to manually and / or automatically assemble the armature assembly, the contact component, and the arc extinguishing component onto the base, and assemble them into a semi-finished base component;

[0061] A base component assembly line 3 is arranged on the other side of the feeding assembly table 1 opposite to the base component assembly line 2, and is used to manually and / or automatically assemble the yoke assembly and the coil assembly onto the base, and assemble them into a semi-finished base component;

[0062] The intermediate assembly line 4 is connected between the base component assembly line 2 and the base component assembly line 3 and is located on the middle section of the feeding assembly table 1. The intermediate assembly line 4 is used to assemble the base semi-finished parts and the base semi-finished parts into a contactor finished product. A U-shaped flow channel structure 5 is extended between the base component assembly line 2, the intermediate assembly line 4 and the base component assembly line 3. The flow channel structure 5 is used to receive the base semi-finished parts and the base semi-finished parts, and guide the base semi-finished parts and the base semi-finished parts to be transported to the intermediate assembly line 4 to complete the assembly of the contactor finished product.

[0063] In the above embodiment, the base component assembly line 2, the intermediate assembly line 4, and the base component assembly line 3 are arranged on the feeding assembly table along the U-shaped interval contour shape, and the contactor product is divided into a base semi-finished component and a base semi-finished component by the base component assembly line and the base component assembly line for synchronous assembly, and the base semi-finished component and the base semi-finished component are bidirectionally transported to the intermediate assembly line 4 through the U-shaped flow channel structure 5, and then the base semi-finished component and the base semi-finished component are assembled to form a contactor finished product through the intermediate assembly line. The advantage of this design is that the base component assembly line 2 and the base component assembly line 3 independently complete the assembly of their respective parts, and finally the intermediate assembly line completes the assembly, which can reduce the waiting time of the assembly process, improve the overall assembly progress, and shorten the time to complete a product assembly. This U-shaped production line design reduces the work site, provides a combination of manual and mechanical automatic assembly methods, has a reasonable process layout, smooth connection between each process and high assembly efficiency, and significantly reduces the number of workers, reduces labor costs and management difficulties, and improves the competitiveness of contactor products.

[0064] In order to transfer the assembled contactor product to the outside of the feeding assembly table 1, the contactor production line provided in this embodiment also includes a discharge channel 6 connected to the flow channel structure 5 on the intermediate assembly line 4, and the discharge channel 6 extends obliquely along one or both sides of the U-shaped section 1 to the U-shaped mouth end of the feeding assembly table. The flow channel structure 4 guides and feeds the materials of the contactor and the finished assembly parts, which can prevent the materials from being mixed and disordered and affecting the assembly efficiency. The discharge channel 6 is connected to the flow channel structure on the intermediate assembly line. When the contactor finished product is assembled on the intermediate assembly line, the contactor finished product is taken out from the feeding assembly table along the obliquely arranged discharge channel 6 to avoid the accumulation of the contactor finished product on the feeding assembly table without affecting other assembly processes.

[0065] As a specific structural arrangement, the flow channel structure 5 includes two straight channels 51 extending in parallel through the base assembly line 2 and the base assembly line 3, referring to Figure 1-3 The discharge channel 6 is staggered with one of the linear grooves 51 at an angle. The advantage of such a design is that the finished contactor slides out toward the open end of the U-shaped section along the discharge channel in a gradually inclined downward trend, and the finished contactor is not higher than the table surface of the feeding assembly table when passing through the base component assembly line 2 or the base component assembly line 3. Finally, it can be smoothly transferred to the outside of the feeding assembly table 1, reasonably optimizing the space, and will not cause any impact on the assembly process on the base component assembly line 2 or the base component assembly line 3. The design is reasonable and the coordination is reliable.

[0066] Combine the following Figure 1-7 The specific setting method of the base assembly line is explained in detail:

[0067] The base assembly line 2 includes an armature assembly unit 21, an arc extinguishing assembly unit 22 and a contact assembly unit 23 which are arranged in sequence from the outside to the inside. Fig.11The first assembled base assembly A is shown, wherein A1 represents a base equipped with an armature, a contact support, an arc extinguishing member and a contact member, the armature assembly assembly unit 21 is used to assemble the armature, the contact support and the base to form a first base assembly, further, the arc extinguishing member assembly unit 22 is used to assemble a plurality of arc extinguishing members to the base of the first base assembly to form a second base assembly, the second base assembly is further transferred along the flow channel structure 5 to the contact member assembly unit 23, and finally, through the contact member assembly The matching unit 23 installs multiple contact pieces onto the base to form the semi-finished base. The contact pieces include main static contacts and auxiliary static contacts. At least one inclined material pulley structure 24 is provided between the armature assembly unit 21 and the arc extinguishing piece assembly unit 22. The material pulley structure 24 can receive material boxes containing assembly materials such as contacts, arc extinguishing pieces, armatures and bases, and can also push out material boxes containing waste materials, so as to facilitate the staff to take and assemble and ensure the timeliness and orderliness of material delivery.

[0070] A movable support platform 72 can enter and exit the accommodating cavity 75 through a guide rail structure, and a plurality of ejector rods 73 are arranged on the movable support platform 72;

[0071] The elastic riveting platform 74 is elastically connected to the plurality of ejector rods 73, and includes a plurality of protruding ends 741 arranged at intervals, and a hollow groove 742 provided with a plurality of ends of the protruding ends and suitable for the ejector rods 73 to be inserted; the arc extinguishing member is sleeved on the protruding end 741 corresponding to the hollow groove, and corresponds to the arc extinguishing groove of the base installed on the elastic riveting platform 74;

[0072] The driving pressure block is movably arranged in the accommodating cavity 75 along the vertical direction. The driving pressure block is driven by the cylinder to move up and down (the driving pressure block is not shown in the accompanying drawings). During the downward pressing process, it applies pressure to the elastic riveting platform 74 by pressing the base, so that the push rod 73 pushes the arc extinguishing member to be stuck in the arc extinguishing groove.

[0073] Through the above-mentioned structural arrangement, when the base and the arc extinguishing member are assembled into the second base assembly, the multiple arc extinguishing members are first sleeved on the raised end of the elastic riveting platform 74, and then the base is installed on the elastic riveting platform 74, so that the multiple arc extinguishing grooves of the base are just opposite to the arc extinguishing members up and down, and the elastic riveting platform is applied with pressure by the driving pressure block pressing the base downward. During the downward pressing process of the elastic riveting platform, the push rod 73 passes through the hollow groove to push the arc extinguishing member, and the multiple arc extinguishing members are synchronously inserted into the arc extinguishing grooves of the base. After the driving pressure block moves upward, the elastic riveting platform 74 will automatically reset to the initial position elastically, so as to facilitate the next riveting operation of the arc extinguishing member. With this structural arrangement, the riveting installation of multiple arc extinguishing members can be realized at one time through the riveting arc extinguishing member device 7. The operation is simple and convenient, and it saves time and effort. The assembly accuracy is high, and there will be no collision damage to the base. The assembly efficiency is high.

From the above, it can be known that during assembly, the base is first positioned and installed in the positioning groove of the base table 81, and then the two driving blocks 83 are driven by the driving cylinder to move toward each other and clamp the base. According to the multiple contact guide grooves 84 corresponding to the multiple contact grooves on the base, the push rod component 85 is moved along the contact guide groove toward one side of the base, and the contacts on the contact guide groove 84 are pushed into the contact grooves of the base accordingly, so that the contacts are assembled on the base to form a semi-finished base part. Finally, the semi-finished base part is removed from the contact assembly device and continued to be transported along the flow channel structure to the intermediate assembly line for final assembly, ensuring the connection and coordination between the upper and lower processes.

With this structural arrangement, the position distance of the base from the left and right sides of the positioning groove can be adjusted through the adjustment rod, that is, when the base is installed into the positioning groove, and the side wall of one side of the base is abutted against the two adjustment rods, the installation position of the base is calibrated at this time, thereby ensuring that the multiple contact grooves on the base correspond to the multiple contact guide grooves on the drive block one by one, and the base is positioned and calibrated in the positioning groove. The installation is convenient and fast, and the installation accuracy is high.

[0077] Combine the following Figure 1-2 The specific setting method of the base assembly line is explained in detail:

[0078] The base assembly line 3 includes a yoke assembly unit 31 and a coil assembly unit 32 which are arranged in sequence from the outside to the inside. Fig.11 The assembled second base component B is shown, wherein B1 represents a base equipped with a yoke, a slide plate, a support, and a coil structure. The yoke component assembly unit 31 and the coil assembly unit 32 are mainly assembled by workers. The yoke component assembly unit 31 is used to install the yoke, the slide plate, the pad, etc. on the base to form a first base component. The first base component assembled by the yoke component assembly unit 31 is transported to the coil assembly unit 32 along the flow channel structure 5. The coil assembly unit 32 is used to assemble the coil structure on the base of the first base component to form a semi-finished base. The discharge channel 6 extends obliquely through the yoke component assembly unit and the coil assembly unit, which will not cause any influence on the assembly process of the yoke component assembly unit 31 and the coil assembly unit 32. The design is reasonable and the coordination is reliable.

[0079] Combine the following Figure 1-2 , Figure 8-9 The specific setting method of the intermediate assembly line is explained in detail:

[0080] The intermediate assembly line 4 includes a final assembly fixture device 9 for assembling the semi-finished base part and the semi-finished base part into a contactor finished product, and the final assembly fixture device 9 includes a limit block assembly 91, a driving structure and an electric tool gun, wherein the limit block assembly 91 is arranged on one side of the arc-shaped bend of the flow channel structure 5, and at least one limit groove area 92 for accommodating the semi-finished base part is provided between the limit block assemblies 91, and the limit groove area 92 is connected to the arc-shaped bend, and one end of the discharge channel 6 is connected to the arc-shaped bend, so that the semi-finished base part and the semi-finished base part can be directly discharged from the flow channel structure 5. The contactor is pushed into the limiting groove area 92 at the arc bend, and after the final assembly to form the contactor product, the finished product can be discharged directly along the discharge channel 6; it is further preferably arranged that the driving structure includes at least one group of pressure rods 93 mounted above the limiting groove area 92 and can perform vertical lifting and lowering movements, and the pressure rods 93 have guide through holes 94 for placing fasteners, and when the pressure rods 93 descend, they are pressed against the base of the semi-finished base part; the electric tool gun penetrates the guide through holes 94 to fix the fasteners between the semi-finished base part and the semi-finished base part, and the fasteners are screws. It can be known from the above structure that the base semi-finished part and the base semi-finished part are placed in the limit groove area 92 in a horizontal position, and the base semi-finished part is limited by the limit groove area, and then the pressure rod 93 is driven down to press against the base of the base semi-finished part, so that the base semi-finished part and the base semi-finished part are squeezed and closed together. The base and the base are respectively provided with threaded holes corresponding to the pressure rod 93, so that the guide through hole inside the pressure rod is connected with the threaded hole, and the electric tool gun is penetrated into the guide through hole of the pressure rod 93 to drive the fastener between the base and the base, so that the base semi-finished part and the base semi-finished part are kept tightly connected and form a contactor finished product. The guide through hole is designed to play a guiding installation role for the fastener, which can prevent the fastener from hitting the edge of the threaded hole of the base and causing damage to the base, avoid material damage, and help improve assembly efficiency and reduce production costs.

[0081] As a preferred embodiment, Fig. 9 As shown, a limited height structure is provided at one end of the limiting groove area 92 facing away from the arc-shaped bend. Since a reaction spring is installed between the base and the pedestal, the semi-finished base part will bounce up to a certain height. The height of the mating connection between the base and the pedestal can be limited within a set distance through the limited height structure, which is convenient for subsequent screw fastening and installation. The limited height structure includes a support plate 95 fixed on the feeding assembly table, and an L-shaped limiting plate 96 arranged on the support plate. The L-shaped limiting plate 96 can be moved and adjusted along the height direction of the support plate 95 by adjusting the bolt structure. The L-shaped limiting plate 96 is pressed against the top of the base to prevent the base from shaking violently or tilting and falling during assembly, and the installation stability is good.

[0082] like Figure 1 As shown, the feeding assembly table 1 includes a mounting bracket arranged around the base assembly line 2, the intermediate assembly line 4 and the base frame assembly line 3, and a multi-layer inclined feeding plate 12 is arranged on the mounting bracket. When there is a shortage of materials and replenishment of materials, the corresponding materials can be directly transported to the corresponding assembly station through the feeding plate to ensure the reliability of the connection of the assembly process.

[0083] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
