Description

Technical Field

[0001] The present application relates to the field of manufacturing technology, and in particular to an assembly device used for assembling integrated components, such as an assembly device for automotive integrated components. Background Art

[0002] Existing assembly equipment, such as assembly production lines, are generally designed and manufactured for a specific product according to specific production capacity requirements. Generally, the production rhythm, that is, the production capacity, of an assembly production line is relatively fixed, that is, the assembly production line is generally dedicated to assembling a specific product, and the production rhythm is relatively fixed. This has the advantages of relatively high production efficiency and strong specialization, but it is relatively difficult to adjust the production rhythm and change the product, and generally cannot be changed. Even if it can be adjusted or modified, the workload is relatively large and the time required is relatively long. For example, the assembly line for assembling automotive integrated components is generally designed based on specific products and specific production capacity. When the product design changes or the product is changed, a new assembly line needs to be replaced or a major modification needs to be made. When the production capacity is increased, a new assembly line needs to be added, which takes a relatively long time. The scrapping of the production line during product replacement leads to waste of resources and relatively increased costs. In addition, automotive components generally require a test adjustment process. In the early development and verification stage, some designs will be changed and some parts will be adjusted. The use of a fixed assembly line requires the manufacture of a new assembly line, which takes a relatively long process. During mass production, the amount of automotive components gradually increases. Therefore, it is necessary to design an assembly equipment that is relatively flexible and has improved versatility, so that it is relatively convenient to replace products or adjust production capacity.

[0034] The following is a description of the specific implementation methods.

[0035] The assembly equipment is suitable for the assembly of various components, such as integrated components for vehicles. The assembly equipment includes a steering mechanism 72, a plurality of universal assembly tables, and a control cabinet 14. The universal assembly tables can be seven, or even more such as ten or more. In addition, a connection device (not shown in the figure) can be selectively configured. The assembly equipment has a control system, and the main control part of the control system can be arranged in the control cabinet 14. Each universal assembly table is provided with an electric cabinet 13, and each universal assembly table can be provided with a control module. The main control part of the control module can be arranged in the electric cabinet 13 of the universal assembly table, or can be partially arranged inside the stand 11. The control cabinet 14 is communicatively connected with the control module of the universal assembly table. A single universal assembly table is generally controlled by its control module. The transmission of the workpiece in the universal assembly table is also transmitted by its conveying mechanism, which is specifically realized by the transmission of the power mechanism 41. The control module is communicatively connected with the action mechanism, operating mechanism, pressing mechanism, etc. of the universal assembly table where it is located. The height of the racks of the universal assembly tables in the assembly equipment is the same, at least the first side 111 or the second side 112 of the universal assembly table that cooperates with other machines is the same as the height of the side of the adjacent universal assembly table that cooperates with it, so as to achieve good transmission and coordination between the two; at least one of the first side 111 and the second side 112 of the universal assembly table cooperates and docks with the adjacent universal assembly table or the connecting device to implement transmission, such as the sixth universal assembly table 206 and the seventh universal assembly table 207 are arranged adjacent to each other, the first side 111 of the sixth universal assembly table 206 cooperates and docks with the second side 112 of the seventh universal assembly table 207, the height of the first side 111 of the sixth universal assembly table is the same as the height of the second side 112 of the seventh universal assembly table, and the position of the first side 111 of the sixth universal assembly table corresponds to the position of the second side 112 of the seventh universal assembly table, so as to achieve the transmission of the workpiece rack between the two universal assembly tables. At least one of the first side 111 and the second side 112 of the universal assembly table can extend out of the rack. For example, the first side 111 and the second side 112 of the sixth assembly table 206 and the first side 111 and the second side 112 of the seventh universal assembly table 207 all extend out of the stand 11. The length of the first side 111 of the sixth assembly table 206 extending out of the stand 11 is relatively short, less than one-third of the workpiece rack 21; the length of the second side of the seventh universal assembly table 207 extending out of the stand 11 is relatively long, close to the length of the workpiece rack. In this article, the operating mechanism is a general term, which can include one or more devices required for a specific operation, and can be configured according to the specific required operation content; the operating mechanism position is a spatial position on the stand that can be used to configure the operating mechanism and install the required operating mechanism, which can also be said to be an operating area, in which the stand is provided with mounting holes, and the mounting holes can be directly matched with the operating mechanism. Here, the mounting holes corresponding to the operating mechanism can have partial cross-overlapping, because different operating mechanisms may be selected during use, some operating mechanisms can be fixed to the stand through connectors, and some other operating mechanisms can be directly fixed to the stand.

[0036] The assembly equipment includes a first universal assembly station 201, a second universal assembly station 202, a third universal assembly station 203, a fourth universal assembly station 204, a fifth universal assembly station 205, a sixth universal assembly station 206, and a seventh universal assembly station 207. The assembly equipment also includes other assembly machines or other machines such as testing machines before the steering mechanism 72, and other assembly machines or other machines such as testing machines after the seventh universal assembly station 207. The assembly equipment also includes a control cabinet 14 and an electric cabinet 13. The steering mechanism 72 of this embodiment is a steering mechanism that rotates and turns after jacking up. Each universal assembly station includes a stand 11 and a conveying mechanism 110. The stand includes a stand seat 113 and a stand plate, and the stand seat 113 is fixed to the stand plate. The stand plate may include two plates, and the fixing member 15 connects the two plates, and / or the fixing member 15 fixes the plate and the stand seat 113. The stand plate may include three plates. The stand seat and plate can be standard settings, the stand seat can have two or three specifications to choose from, and the stand plate matching the stand seat can have two or three specifications to choose from, which is convenient for processing and manufacturing. The universal assembly table can be assembled into a universal assembly table by selecting the stand seat and plate according to the assembly work required.

[0037] The first universal assembly table 201 includes a stand 11, and the stand 11 includes a stand seat 113, a stand plate 100, and a fixing member 15. The fixing member 15 is fixedly connected to the first plate 1001, the second plate 1002 and the stand seat. The assembly equipment is fixedly provided with a first action mechanism 31, a second action mechanism 32, a feeding mechanism 60, a vibration feeding mechanism 51, an auxiliary material feeding mechanism 53, two sets of press-fitting mechanisms 71, and a plurality of operating mechanisms on the first universal assembly table 201. The fixing of these mechanisms in this article means that the fixed part of the mechanism is fixed to the stand or the stand plate, while the part used for action and operation can be operated movably. The second side 112 of the first universal assembly table 201 cooperates with the steering mechanism 72 or the connecting device, and the first side 111 of the first universal assembly table 201 cooperates with the second universal assembly table 202 or the connecting device. The height of the first side of the conveying mechanism of the first universal assembly table is the same as the height of the second side of the conveying mechanism of the second universal assembly table, and the conveying mechanism of the first universal assembly table cooperates with the second conveying mechanism for relative transmission. The feeding position of the feeding mechanism 60 is within the action range of the first action mechanism 31. The first action mechanism 31 can deliver the components at the corresponding position of the feeding mechanism 60 to the corresponding position of the workpiece. The actions of the first action mechanism 31 may include scanning codes and transporting, etc.; the actions of the operating mechanism may include one or more of the following operations: inspection of auxiliary materials such as sealing rings, oiling, taking photos, inspection after operation, and transporting. The vibration feeding mechanism 51 realizes the feeding of auxiliary materials by vibration feeding such as a vibration plate, such as sending the retaining ring to the press-fitting sleeve; the second action mechanism can detect or transport the press-fitting sleeve to the workpiece 20 to be assembled; the press-fitting mechanism 71 assembles the workpiece and the corresponding parts, and the press-fitting mechanism 71 can specifically perform crimping or screw connection, such as assembling the parts to the workpiece through screws, retaining rings and other auxiliary materials, and the auxiliary materials can be connected to the corresponding feeding mechanism through a nail feeding tube, and the screws are sent to the press-fitting mechanism through the feeding mechanism; in addition, during assembly or press-fitting, synchronous detection can also be performed by the operating mechanism to detect whether the assembly is in place; in addition, the action mechanism can also include a rotating mechanism, which can rotate the workpiece rack 21 together with the workpiece to a preset angle, such as 90 degrees or 180 degrees, so that the remaining operating mechanisms can operate on the workpiece in another direction. Before some actions are performed, the parts or working conditions can also be confirmed by scanning the code, or by shooting and judging whether the good or bad products are good. The first universal assembly table 201 includes a conveying mechanism 110, and the two ends of the conveying mechanism 110 slightly extend out of the stand 11. The conveying mechanism is at least partially located above the platform, and the workpiece rack is located on the conveying mechanism. The conveying mechanism includes a power mechanism 41, such as a motor, which can drive the chain belt of the conveying mechanism 110 to move forward or backward to realize the transmission of the workpiece rack on the conveying mechanism and the transmission of the workpiece on the workpiece rack. The first universal assembly table 201 also has a relatively independent control module to control the operating mechanism and the action mechanism, etc., so that the universal assembly table can operate automatically.The universal assembly table 201 includes a lifting mechanism 73, which lifts up the workpiece rack and the workpieces carried by it that are transported to the working position to achieve relative fixation during operation, and limits their position to facilitate operation.

[0038] The stand may include a stand seat and a stand plate. When assembling a larger component, the stand plate may include two plates, or the stand 11 may include two stand parts 11a and 11b. The stand part 11a includes a stand seat 113a and a first plate 1001, and the stand part 11b includes a stand seat 113b and a second plate 1002. The stand part is assembled by combining the stand seat and the plate, and the two stand parts are combined with a connecting plate 15, screws, etc. to form a stand. When assembling a general component, the stand plate may be an integral structure.

[0039] The second universal assembly table 202 includes a stand 11 and a conveying mechanism 110. The stand 11 includes a stand seat 113 and a stand plate 100. The stand seat 113 is fixed to the stand plate 100. The stand plate can be integrated or include two plates, such as a first plate 1001 and a second plate 1002. The fixing member 15 connects the two plates and the stand seat or connects the stand plate and the stand seat. The assembly equipment is fixedly provided with a first action mechanism 31, a second action mechanism 32, two groups of feeding mechanisms 60, a first operating mechanism, a second operating mechanism, a lifting mechanism, etc. on the second universal assembly table 202. The feeding positions of the two groups of feeding mechanisms 60 are located in the action range of the first action mechanism 31. The feeding mechanisms 60 cooperate with the first action mechanism 31. The first action mechanism 31 can respectively send the parts on the two groups of feeding mechanisms 60 to the corresponding required positions of the workpiece, which can be the same position or different positions, such as sending the parts on the first feeding mechanism 60 to the first position and sending the parts on the second feeding mechanism 60 to the second position. The second side 112 of the second universal assembly table 202 is matched with the first side 111 of the first universal assembly table 201, and the first side 111 of the second universal assembly table 202 is matched with the second side 112 or the connecting device of the third universal assembly table 203. The conveying mechanism includes a power mechanism 41. The first operating mechanism is fixed to the stand through a connecting piece, and can perform actions such as detection on the parts or auxiliary materials located in the first operating position. After the detection and other actions are completed, the parts or auxiliary materials can be temporarily stored in the waiting position; the remaining operating mechanisms are fixed to the stand, and can perform other actions on the same parts or auxiliary materials or perform actions such as detection on different auxiliary materials. If the universal assembly table also has a second operating position, the assembly equipment can perform operations such as opening on the parts or auxiliary materials such as sealing rings located in the second operating position, and the second action mechanism 32 can grab one of the auxiliary materials and the parts to realize the assembly of the two, and then put the assembled parts into the corresponding position of the workpiece. The assembly equipment can also have a non-good grade on the universal assembly table, and the parts or auxiliary materials located in the non-good grade are sent out and no longer participate in the assembly.

[0040] Universal assembly tables are all equipped with relatively independent conveying mechanisms, which may include chain belts such as mesh belts, or chain plates, double-speed chains, etc., and may also be roller conveying, that is, including multiple rollers that can rotate under control, and the workpiece rack is placed on the rollers to achieve conveyance. The conveying position or action position of the conveying mechanism is relatively close to the ends on both sides. The conveying mechanism is fixed with the stand, or it can be fixed or limited by clamping. The operating mechanism is located on one side of the conveying mechanism, the fixed part of the action mechanism can be located on the same side, and the main body of the pressing mechanism can be located on the other side of the conveying mechanism, that is, the fixed parts of the pressing mechanism and the action mechanism are respectively located on opposite sides of the conveying mechanism, the pressing mechanism position and the first operating mechanism position are respectively located on opposite sides of the conveying mechanism, and the first operating mechanism position, the connecting piece and the first action mechanism position are located on the same side of the conveying mechanism.

[0041] The action mechanism is fixed or limited to the stand, and the fixing method may be screws combined with positioning pins. Here, the action mechanism is fixed or limited to the stand, which means that the part of the action mechanism used for fixed installation, that is, the fixed part, is fixed or limited to the stand, while the other parts that can move can move relative to the stand and perform operations; the operating mechanism is fixed or limited to the stand, which means that the part of the operating mechanism used for fixed installation, that is, the fixed part, is fixed or limited to the stand, including direct and through connecting parts, while the other parts that can move can perform action operations. The conveying mechanism is fixed or limited to the stand, which means that the part of the conveying mechanism used for fixed installation, that is, the fixed part, is fixed or limited to the stand, while the other parts that can move can perform action operations.

[0042] The third universal assembly station 203 and the fourth universal assembly station 204 are similar to the second universal assembly station, and both include a stand 11, and the stand 11 includes a stand seat 113 and a stand plate 100, and the stand seat 113 is fixed to the stand plate. The stand plate can be integrated or include a first plate 1001 and a second plate 1002, and the fixing member 15 connects the two plates, or the fixing member 15 connects the stand plate and the stand seat, or the fixing member 15 fixes the two plates and the stand seat. The assembly equipment is provided with a first action mechanism 31 and a second action mechanism 32 on the third universal assembly station 203, and can also be provided with a third action mechanism, two sets of feeding mechanisms 60, and a first operating mechanism, etc. The first feeding mechanism 60 and the second feeding mechanism 60 cooperate with the first action mechanism 31, and the first action mechanism 31 can deliver the parts at the corresponding positions of the first feeding mechanism 60 and the second feeding mechanism 60 to the required positions; the second side of the third universal assembly station 203 cooperates and docks with the second universal assembly station 202, and the first side of the third universal assembly station 203 cooperates and docks with the fourth universal assembly station 204. The third universal assembly station 203 also includes a conveying mechanism 110, and the conveying mechanism includes a power mechanism 41. The third universal assembly station 203 also has a relatively independent control module to realize the relatively automatic operation of the universal assembly station.

[0043] The fourth universal assembly table 204 includes a stand 11, and the stand includes a stand plate 100 and a stand seat 113. The stand plate 100 can be integrated or include two plates 1001 and 1002. The fixing member 15 connects the two plates and the stand seat. The first side of the fourth universal assembly table 204 is docked with the fifth universal assembly table. The assembly equipment is provided with a first action mechanism 31, a second action mechanism 32, a feeding mechanism 60, a first operating mechanism, a second operating mechanism, etc. on the fourth universal assembly table 204; in addition, a vibration feeding mechanism and an auxiliary material feeding mechanism can also be provided. Other aspects of the third and fourth universal assembly tables can refer to the above-mentioned first and second universal assembly tables, which will not be repeated here.

[0044] The fifth universal assembly station 205 includes a stand 11', and the stand 11' includes a stand seat 113' and a stand plate 110'. In this embodiment, the width L2 of the stand 11' along the workpiece conveying direction of the assembly equipment, the width L0 of the first universal assembly station, the second universal assembly station, the third universal assembly station, and the fourth universal assembly station along the workpiece conveying direction of the assembly equipment is twice or three times L2, and the width of the stand plates of the first universal assembly station, the second universal assembly station, the third universal assembly station, and the fourth universal assembly station are the same. The same in this article means that there may be a certain processing tolerance within the tolerance range of the two. The fifth universal assembly station 205 is provided with a first action mechanism 31, a second action mechanism 32, a feeding mechanism 60, a pressing mechanism 71, and a number of operating mechanisms, and can also have a vibration feeding mechanism and an auxiliary material feeding mechanism. The second side 112 of the fifth universal assembly station 205 cooperates with the fourth universal assembly station 204, and the first side 111 of the fifth universal assembly station 205 can cooperate with other machines or connecting devices. The first action mechanism 31 can deliver the parts corresponding to the position of the feeding mechanism 60 to the required position; the fifth universal assembly station 205 also has a relatively independent control module to realize the automatic operation of the universal assembly station. In this universal assembly station, the operating mechanism can also include a detection device. When the detection device detects a non-conforming product, the parts or auxiliary materials located in the waiting position can participate in the operation, which can reduce the waiting time required due to the detection of non-conforming products. The action mechanism position, the operating mechanism position, and the press-fitting mechanism position set in the fifth universal assembly station are less than those in the other four universal assembly stations. In a specific embodiment, the rack of the fifth universal assembly station is provided with two groups of action mechanism positions, more than one group of operating mechanism positions, and one group of press-fitting mechanism positions. The racks of other universal assembly stations are provided with three to six groups of action mechanism positions, more than three groups of operating mechanism positions, and more than two groups of press-fitting mechanism positions. The fifth universal assembly station is also provided with a relatively independent conveying mechanism 110'. The length of the conveying mechanism 110' in this embodiment is roughly the same as the length of the conveying mechanism 110 of the other four universal assembly stations, so that the replacement of the universal assembly station is relatively convenient in the future. In addition, the length of the conveying mechanism may be approximately half or one third of the length of the conveying mechanism of other general assembly stations.

[0045] The sixth universal assembly station 206 is similar to the first universal assembly station 201, and includes a stand 11 and a conveying mechanism 110. The stand 11 includes a stand seat 113 and a stand plate 100, and the stand seat 113 is fixed to the stand plate. The stand plate can be integrated or include two plates, and the fixing member 15 connects the two plates and the stand seat. The stand plate can also include three plates. The assembly equipment is provided with a first action mechanism 31, a second action mechanism 32, a feeding mechanism 60, a vibration feeding mechanism 51, a pressing mechanism 71, and a plurality of operating mechanisms and a conveying mechanism 110 on the sixth universal assembly station 206. The second side of the sixth universal assembly station 206 cooperates with the fifth universal assembly station or the connecting device, and the first side 111 of the sixth universal assembly station 206 cooperates with the seventh universal assembly station 207 or the connecting device. The height of the first side of the conveying mechanism of the sixth universal assembly station is the same as the height of the conveying mechanism of the adjacent assembly station, or the same as the height of the adjacent docking connection device, and the height of the second side of the sixth universal assembly station is the same as the height of the conveying mechanism of the adjacent assembly station, or the same as the height of the adjacent docking connection device. For example, in this embodiment, the conveying mechanism of the sixth universal assembly station cooperates with the fifth conveying mechanism on the second side for transmission, and the height of the docking parts is substantially the same; the first side of the sixth universal assembly station 206 cooperates with the seventh universal assembly station for docking and transmission, and the height of the docking parts is substantially the same.

[0046] Similarly, the first side of the seventh universal assembly station 207 is docked with other assembly stations of the assembly equipment or with the connecting device, and the second side of the seventh universal assembly station 207 is docked with the first side of the sixth universal assembly station; the height of the conveying mechanism of the seventh universal assembly station on the second side is the same as the height of the conveying mechanism of the sixth universal assembly station adjacent to it. Other aspects of the seventh universal assembly station 207 can refer to the universal assembly stations described above, and will not be repeated here.

[0047] The assembly equipment includes a control cabinet 14, which can realize the overall control of the assembly equipment and the coordination between the universal assembly tables. The control cabinet 14 is connected to the control modules of at least some of the universal assembly tables in communication. The assembly action of a single universal assembly table is generally controlled by its own control module, and adjacent universal assembly tables can also be connected to each other in communication. In the above embodiment, each universal assembly table includes its own control module and conveying mechanism 110, 100', and the transmission of the workpiece on the universal assembly table is also driven by the power mechanism 41 of its conveying mechanism. The workpiece rack is at least partially located above the conveying mechanism and is driven by the chain belt. The control module is connected to the action mechanism, the pressing mechanism and other operating mechanisms in communication. The height of the rack 11 of the universal assembly table in the assembly equipment is basically the same, and at least the side of the universal assembly table that cooperates with other machines is basically the same as the height of the side of the adjacent universal assembly table; at least one of the first side and the second side of the universal assembly table cooperates with a side or a connecting device of the universal assembly table of the assembly equipment adjacent to this side of the universal assembly table. At least part of the universal assembly table is provided with a connecting piece 80, two or more sets of operating mechanisms are fixed or limited with the connecting piece, the connecting piece of the assembled operating mechanism is fixed with the stand, and the operating mechanism is fixed with the connecting piece, which is more convenient than fixing two or more sets of operating mechanisms with the table. The mechanism assembled with two or more sets of operating mechanisms and connecting pieces is defined as an operating mechanism assembly. When replacing different workpieces, the operating mechanism may need to be adjusted. The operating mechanism assembly for different workpieces can be reserved, and the operating mechanism assembly can be directly replaced, which is relatively convenient and fast, and can improve the versatility and flexibility of the assembly equipment, and the adaptability of the assembly equipment is relatively stronger.

[0048] The universal assembly station can be connected to the adjacent universal assembly station by communication, mainly to obtain the transmission or waiting of the workpiece rack, and to transmit and receive the required signals. Generally, each universal assembly station has no less than two operating positions, and the operating position can limit the workpiece rack after it is in place and facilitate the operation of the workpiece on the workpiece rack. The operating position is set in the corresponding space in the conveying mechanism and above. After the workpiece rack reaches the operating position, it can be limited by the action of the limiting mechanism 78, and it can be judged whether it carries the workpiece or whether the workpiece is normal. When it is normal, the workpiece rack is lifted by the lifting mechanism 73 and is relatively fixed. The universal assembly station can perform corresponding operations on the workpiece carried by the workpiece rack. After the operation is completed, the lifting mechanism 73 and the limiting mechanism 78 can be activated by communication or by the control module, and the workpiece rack 21 returns to the conveying mechanism and can continue to circulate with the conveying mechanism. When the operation of the general assembly station below has not been completed, the workpiece rack cannot circulate. At this time, the control can be realized by the information transmission of the control modules of the two. The workpiece rack can first wait at the waiting position and wait for the signal of the next general assembly station to continue. Therefore, a waiting position can be set between two adjacent universal assembly stations, and a limit mechanism 78 can be set. The limit mechanism 78 is generally set at the next universal assembly station of the adjacent universal assembly stations. From the direction of the workpiece rack transmission, the limit mechanism 78 is located in front of the working position, or in front of the lifting mechanism 73. From the top view, the limit mechanism 78 is located in the conveying mechanism, and accordingly, the waiting position is at least partially located in the conveying mechanism, or the waiting position is partially located in the previous universal assembly station, and the other part is located in the next universal assembly station. The limit mechanism can be in the limit state by default, and no longer limit when receiving the control signal, or the action of the limit mechanism is realized by turning on and off the power of the control module. The waiting position can be set in front of the working position of the universal assembly table. In this case, the limiting mechanism of the waiting position is controlled by the control module of the universal assembly table. It can also be set behind the working position of the universal assembly table. In this case, the universal assembly table needs to communicate with the next universal assembly table. It can also be set between two racks, such as a docking position, or between the working positions of two adjacent universal assembly tables. The waiting position is a relatively virtual space, and the workpiece rack can be limited to this space, at least most of it is located above the conveying mechanism.

[0049] The following is an example of an adjacent universal assembly table. Figure 2-Figure 4, the first universal assembly table 101 is adjacent to the second universal assembly table 102, the first universal assembly table 101 is provided with three working positions: 210, 220, 230; the second universal assembly table 102 is provided with three working positions: 210, 220, 230, the two universal assembly tables have a waiting position 240 at the relative matching docking position or before and after, the waiting position 240 can be used to temporarily limit the workpiece rack, the waiting position 240 is located behind the working position of the first universal assembly table, that is, close to the side of the second universal assembly table, or located in front of the working position of the second universal assembly table, that is, close to the side of the first assembly table, or located near the docking position of the two. A limiting mechanism 78 is set at the position corresponding to each working position, so that the workpiece rack is accurately limited to the working position, and the lifting mechanism corresponds to the position of the workpiece rack. When the universal assembly table requires relatively few working positions, the extra working positions can be used as waiting positions or vacant, and the universal assembly table can no longer set a waiting position separately; if the universal assembly table is provided with three working positions, only two of them are needed as working positions, and the other one can be used as a waiting position. The first side 111 of the first universal assembly table 101 is docked with the second side 112 of the second universal assembly table 102, the height of the first side of the first universal assembly table is the same as the height of the second side of the second universal assembly table, the position of the first side of the first universal assembly table corresponds to the position of the second side of the second universal assembly table to realize the transfer of the workpiece rack between the two universal assembly tables, the height of the conveying mechanism of the first universal assembly table is the same as the height of the conveying mechanism of the second universal assembly table, and the conveying mechanism of the first universal assembly table and the conveying mechanism of the second universal assembly table cooperate with each other for conveyance. When a conveying mechanism is configured on the universal assembly table, the length L1 of the conveying mechanism in its conveying direction is greater than or equal to the width L0 of the platform in this direction, the conveying mechanism is flush with the platform 11 on the first side or the conveying mechanism slightly extends from the platform, and the conveying mechanism can be flush with the platform on the second side or the conveying mechanism extends from the platform. Specifically, the first side and the second side of the conveying mechanism can partially extend from the platform 11, so that the adjacent universal assembly tables can be relatively convenient to cooperate and dock; the extended part can be used to set the waiting position or cooperate with the adjacent extended part to set the waiting position, and the extended length can be close to the length of the workpiece rack 21, not exceeding the length of the workpiece rack 21. The first universal assembly table and the second universal assembly table are both provided with a first operating mechanism 75, and can also have a second operating mechanism 76. The first operating mechanism here can be a combination of multiple operating mechanisms, so that it is more convenient to set it through a connecting piece. The first operating mechanism 75 can perform a series of actions such as detection on the parts or auxiliary materials located at the first operating position 501. The first operating mechanism 75 can operate on more than two stations, each station can perform different operations, and can transmit the object of the operation through a smaller conveying mechanism set on the workbench.The waiting position 50 for parts or auxiliary materials can also be set in the working range of the operating mechanism of the universal assembly table. The parts or auxiliary materials after the detection and other actions are completed can be temporarily stored in the waiting position 50. The second operating mechanism 76 can also perform other actions on the same parts or auxiliary materials or detect different auxiliary materials, and can also have a waiting position. The assembly equipment can also have a second operating position 502 or even a third operating position on the universal assembly table. The operating mechanism can perform operations such as opening on the parts or auxiliary materials such as sealing rings located at the second operating position 502. The second operating mechanism 32 can grab one of the auxiliary materials and parts to realize the assembly of the two, such as screw connection. The second operating mechanism 32 then puts the assembled parts into the corresponding position of the workpiece. The press-fitting mechanism 71 can assemble the workpiece and the parts, etc. The press-fitting mechanism 71 specifically performs press-fitting or screw connection operations. The press-fitting mechanism 71 can be connected to the corresponding feeding mechanism through a nail feeding tube, and the screws are sent to the press-fitting mechanism through the feeding mechanism. The assembly equipment may also have a non-conforming position 503 on the universal assembly table, and the action mechanism sends the parts or auxiliary materials located at the non-conforming position 503, such as to the area corresponding to the non-conforming products.

[0050] Operations on the workpiece rack located on the conveying mechanism are generally performed on the workpiece, that is, operations are performed on the workpiece on the workpiece rack located at the working position; operations on the stand located outside the conveying mechanism are generally performed on parts or auxiliary materials, etc., and the universal assembly table can assemble at least one part or auxiliary material.

[0051] The first universal assembly table 101 includes two rack parts 11a and 11b, which are fixedly connected by fixing parts 15, etc. The frames of the two rack parts are the same, and the various mechanism positions thereon are symmetrically arranged with the matching positions of the two as the central axis. For example, the rack part 11a has a first action mechanism position 310 arranged at a position relatively far away from the rack part 11b and close to the conveying mechanism 110, and the rack part 11b has a first action mechanism position 310 arranged at a position relatively far away from the rack part 11a and close to the conveying mechanism 110. The specific settings of these two action mechanism positions are the same but not symmetrical. The symmetrical setting here is not completely symmetrical, but symmetrical in terms of the approximate center of each mechanism position, and the mounting holes of the mechanism positions are asymmetrical. In addition, the action mechanism position can also be arranged at the position where the two rack parts are connected, and part of the mounting holes of the action mechanism position are located in the rack part 11a, and the other part is located in the rack part 11b. The second universal assembly table includes two rack parts, which are fixedly connected by fixing parts 15, etc. The frame structures of the rack parts are the same, and the arrangement of the mechanism positions is roughly symmetrical. Each rack part is at least provided with a first action mechanism position 310, a second action mechanism position 320, two operation mechanism positions 760, 750, and one to two press-fitting mechanism positions 710. In this way, the rack part is arranged as a universal rack structure, which is relatively convenient for manufacturing and assembly. In addition, the structures of the two rack parts can be made the same, and the universal assembly table can select the same rack part. A single universal assembly table can include one rack part, two rack parts, or three rack parts.

[0052] The above-mentioned universal assembly table is configured with a conveying mechanism for each universal assembly table, or each rack part can be configured with a conveying mechanism, so that the conveying mechanism and the rack part can be assembled first, and then the two rack parts can be assembled, or even assembled at the last time when the assembly equipment is assembled. The universal assembly table can also be configured with a vibration feeding mechanism 51 and an auxiliary material feeding mechanism 53. There can also be a feeding pipe (not shown in the figure) between the auxiliary material feeding mechanism 53 and the action mechanism to deliver auxiliary materials such as nails used for assembly to the corresponding position of the workpiece or the action mechanism.

[0053] The conveying mechanism 110 includes a chain belt 1100, and the two exposed parts on the front and back sides of the chain belt are defined as a first part 1101 and a second part 1102, which are also the two parts where the chain belt and the workpiece rack can act. The first part 1101 where the chain belt of the first universal assembly station can cooperate with the workpiece rack is relatively close to the end 1111 on this side of the conveying mechanism, and the second part 1102 where the chain belt of the second universal assembly station can cooperate with the transmitted workpiece rack is relatively close to the end 1112 on the corresponding side of its conveying mechanism. In order to ensure the smooth transmission of the workpiece rack, a roller 822 can be set at the end position of the universal assembly station near the conveying mechanism, and the top of the roller 822 is roughly flush with the top height of the chain belt 1100. The roller 822 can be set on both sides of the conveying mechanism; the roller 822 can be set on one side of the transmission direction of the universal assembly station, or on both sides. The first part of the chain belt of the first universal assembly station is relatively close to the second part of the chain belt of the second universal assembly station, and the distance between the two is less than one-half of the transmitted workpiece rack along this direction, or even one-third. The two rollers 822 located on the first side of the universal assembly table are respectively located between the end 1111 of the first side and the first part 1101 of the chain belt. The chain belt will be driven to move. The first part here is also a relative position that the chain belt can reach, and the second part is the same; the roller 822 located on the second side of the stand is located between the end 1112 of the second side of the stand and the second part 1102 where the chain belt is close to the end. The inner side 821 of the universal assembly table on the first side is lower than the top of the chain belt 1100, so that the workpiece rack 21 placed on the top of the chain belt 1100 will not be blocked. The universal assembly table has a limiting portion 823 on the outer side of the first side, and the limiting portion 823 is higher than the top of the chain belt 1100. This can play a role in relative limiting the workpiece rack 21 placed on the top of the chain belt 1100, thereby ensuring reliable transportation of the workpiece rack during the transportation process; in order to ensure reliable transportation, the universal assembly table even sets a plurality of limiting portions in sections on the outer side of the chain belt, and the limiting portions are higher than the top of the chain belt 1100, and the conveying mechanism is lower than the top of the chain belt 1100 on the inner side of the chain belt and close to the chain belt.

[0054] When the universal assembly table has two rack parts, each rack part is provided with a first action mechanism position 310, a second action mechanism position 320, a first operating mechanism position 750, a second operating mechanism position 760, and a press-fitting mechanism position. The first action mechanism position 310 has a mounting hole 3101 for mounting with the first action mechanism, and the second action mechanism position 320 has a mounting hole 3201 for mounting with the second action mechanism. The action mechanism position can be used for the mounting of the action mechanism, such as the action mechanism being fixedly mounted relative to the rack by screws, specifically, the part of the action mechanism used for mounting is fixed to the rack, and the action mechanism must have a part to perform the operation, and this part is movable, such as it can grab and move the parts to be assembled from the feeding mechanism to the workpiece. The universal assembly table can have three groups of first action mechanism positions 310, one of which can be set in the relatively middle area of ​​the two rack parts, that is, the mating and docking position of the two rack parts. The first operating mechanism position 750 has a mounting hole 7501 for mounting with the first operating mechanism, and the second operating mechanism position 760 has a mounting hole 7601 for mounting with the second operating mechanism; the first action mechanism position 310 is used for mounting and fixing the first action mechanism, the second action mechanism position 320 is used for mounting and fixing the second action mechanism, the first operation mechanism position 750 is used for mounting and fixing the first operation mechanism, and the first operation mechanism can be an operation mechanism assembly, including a connecting piece and more than two operation mechanisms. The second operation mechanism position 760 is used for mounting and fixing the second operation mechanism. The first operation mechanism position 310 generally does not overlap with the second operation mechanism position 320 and the two operation mechanism positions, and the first operation mechanism position 750 generally does not overlap with the action mechanism position and the second operation mechanism position 760, that is, they are staggered. When the general assembly table requires fewer mechanisms to be operated and worked, the general assembly table can select only one bench section and configure the relatively required action mechanisms and operating mechanisms to meet the needs. When the assembly requires relatively more mechanisms to be operated, two or even three bench sections can be selected. In this way, relatively more action mechanisms and operating mechanisms can be set up, and the bench sections can be relatively standardized. When the production capacity demand changes, adjustments can also be made in this way. In this way, the assembly equipment is relatively flexible and the adjustments can be completed quickly.

[0055] When the universal assembly table has two rack parts, the two rack parts are respectively provided with a plurality of mounting holes. The two rack parts are respectively provided with an action mechanism position 310, a second action mechanism position 320, a first operating mechanism position 750, a second operating mechanism position 760, and two groups of press-fitting mechanism positions 710, and each mechanism position has a corresponding mounting hole for matching installation. The universal assembly table can also have a third group of first action mechanism positions 310, one group of which is respectively provided in the two rack parts, and another group can be provided in the relatively middle position of the two rack parts. The universal assembly table has a conveying mechanism 110, and the conveying mechanism 110 is fixed to the rack part by fixing parts 16 and the like.

[0056] The installation positions and racks of the various mechanisms of the universal assembly table can be found in Figure 5-Figure 8 , Figure 5 It is a three-dimensional schematic diagram of the frame and conveying mechanism of a universal assembly table, and the universal assembly table is not provided with an action mechanism; Figure 6 yes Figure 5 A schematic top view of a universal assembly station is shown, Figure 7 This is a rear view diagram. Figure 8 It is a partial enlarged schematic diagram. In order to make the universal assembly table easy to move, flexible to replace and assemble, and the assembly equipment can be adjusted conveniently and quickly when replacing the assembled workpiece or adjusting the output, the universal assembly table is provided with a height adjustment member 12, a wheel, and a fixed reinforcement part 18. The wheel can be a Foma wheel 17. The height of the height adjustment member and the fixed reinforcement part 18 can be adjusted within a certain range, and the fixed reinforcement part 18 can also have a screw hole or a mounting hole, which is convenient for fixing to the ground through bolts, etc. In this way, when the universal assembly table needs to be moved, the height adjustment member 12 and the fixed reinforcement part 18 are adjusted to make the Foma wheel contact with the ground, which is convenient for movement; after moving into place, the relative position can be limited, and then the height adjustment member 12 and the fixed reinforcement part 18 are adjusted to make the height adjustment member and the fixed reinforcement part 18 contact with the ground or a fixed part, and the fixed reinforcement part 18 can be further fixed to the ground through bolts, etc., and the height adjustment member and the fixed reinforcement part 18 can make the height of the universal assembly table finely adjusted, which is convenient for docking with adjacent stands, etc. The conveying mechanism 110 may also have a height adjustment member 12a, the height of which can be adjusted within a certain range, and two or four height adjustment members 12a may be provided. The height adjustment member 12, the height adjustment member 12a, and the fixed reinforcement member 18 have a certain height adjustment range, including the position where the wheel contacts the ground, that is, the height adjustment member 12, the height adjustment member 12a, and the fixed reinforcement member 18 are higher than the position where the wheel contacts the ground when they are at their highest, and the lowest adjustable position of the height adjustment member 12, the height adjustment member 12a, and the fixed reinforcement member 18 is lower than the contact position of the wheel 17, even if there is a gap between the wheel and the ground, or in other words, the height of the height adjustment member and the fixed reinforcement member can be adjusted within a certain range, and the height adjustment range of the height adjustment member and the fixed reinforcement member includes the lowest position of the wheel. The fixed reinforcement member 18 has a bending portion 181, which is fixedly reinforced with the ground, and can be achieved by bolts. Generally, each universal assembly table can be provided with 6 height adjustment members 12. When 6 members are provided, one is provided at each corresponding position of the four corners of the bottom and one is provided at each of the two sides of the middle. If the universal assembly table has only one platform, 4 height adjustment members 12 can be provided, one is provided at each corresponding position of the four corners of the platform. 4 Foma wheels can be provided, which are respectively provided at the relatively inner positions of the four corners of the bottom of the universal assembly table. 8 height adjustment members can also be provided as shown in the figure, with 3 at the bottom of each side.

[0057] Ginseng Figure 6The universal assembly table is provided with three working positions, and a lifting mechanism 73 can be provided at least two of the three working positions. When used as a waiting position, a lifting mechanism may not be provided, and a lifting mechanism is provided when used as a working position. The universal assembly table is also provided with a limiting mechanism 78 for each working position. The limiting mechanism 78 is provided behind the working position so that the workpiece rack can be relatively accurately limited when it comes over. After the workpiece rack is in place, the lifting mechanism 73 can be lifted up according to the control and the operation can be performed. A proximity sensing element 79 can also be provided at or before the working position. The proximity sensing element can be a proximity switch, a proximity sensor, an infrared receiving sensor, etc. When the workpiece rack is delivered, the control module can receive the signal of the proximity sensing element 79 to facilitate automatic control. The front and back here refer to the delivery direction of the workpiece rack. The platform plate is also provided with a plurality of holes 36 for the wire harness and the air pipe to pass through. The wire harness for communication or control of the operating mechanism, the action mechanism, the sensing element, etc. can pass through the hole. In addition, the air pipe of the control element can also pass through the hole into the platform.

[0058] The conveying mechanism 110 is fixed to the frame, specifically fixed by fixing parts 16 and screws. At least most of the chain belt 1100 of the conveying mechanism 110 is located above the frame and exposed. The workpiece rack can be limited to be located above the chain belt. When the chain belt is in motion, it drives the workpiece processing and the workpiece on the workpiece rack to be transmitted together.

[0059] The universal assembly table can be equipped with a set of conveying mechanisms, or a set of conveying mechanisms can be equipped with a platform part. Fig. 9 , Fig. 9It is a schematic diagram of another embodiment of a universal assembly table of an assembly device. The main difference between this embodiment and the above-mentioned embodiment is the setting of the conveying mechanism. The universal assembly table includes a table seat and a table plate 100, the table plate 100 includes a first plate 1001 and a second plate 1002, the table includes a first table part 11a and a second table part 11b, the first table part 11a is equipped with a conveying mechanism 110a, and the second table part 11b is equipped with a conveying mechanism 110b, and the conveying mechanism 110a and the conveying mechanism 110b have a power mechanism 41 and a chain belt. On the first side 111 of the universal assembly table, the conveying mechanism 110b partially extends out of the second table part 11b, and the other side 1103 of the conveying mechanism 110b is basically aligned with the second table part; on the second side 112 of the universal assembly table, the conveying mechanism 110a partially extends out of the first table part 11a, and the other side 1104 of the conveying mechanism 110a is basically aligned with the first table part 11a. In addition, the conveying mechanism 110b can also be roughly aligned with the platform part 1102 on the first side, and the conveying mechanism 110a can also be roughly aligned with the platform part 1101 on the second side. The length L4 of the conveying mechanism 110a along the conveying direction is greater than or equal to the width L2 of the first platform part 1101 along the conveying direction, and the length L4 of the conveying mechanism 110b along the conveying direction is greater than or equal to the width L2 of the second platform part 1102 along the conveying direction. The advantage of this arrangement is that the platform part is relatively independent, the coordinated assembly of the platform part and the conveying mechanism can be completed first, and the assembly between the two platform parts can be carried out together at the end, that is, it is relatively convenient to assemble the assembly equipment, and the assembly equipment can be adjusted more conveniently and quickly when replacing the assembled workpiece or adjusting the output. The assembly equipment can select one platform part or two platforms to assemble into a universal assembly table, and other structures of the universal assembly table can refer to the above embodiment. The universal assembly table is provided with three working positions 210, 220, 230 and a waiting position 240. The corresponding positions of the working position and the waiting position are provided with corresponding limiting mechanisms 78, and the limiting mechanism 78 is electrically connected or communicated with the control module. One form of the limiting mechanism 78 may include a cylinder and a control valve, and the cylinder is activated by controlling the on and off of the control valve to achieve limiting and releasing. In addition, a proximity sensing element 79 may be provided on the other side of the working position or the waiting position, and the proximity sensing element 79 is electrically connected or communicated with the control module. The limiting mechanism may also be directly controlled electrically or by electromagnetic control.

[0060] The universal assembly table can be equipped with multiple operating mechanisms. Figure 10-12 , Fig.10 is a partial schematic diagram of another embodiment of a universal assembly station for assembling equipment, Fig.11 is a three-dimensional schematic diagram of the frame of the universal assembly table, Fig.12It is a schematic top view of the stand of the universal assembly table. The universal assembly table includes two stand parts, and the stand has a stand seat 113 and a stand plate 100. The first stand part 11a is equipped with a conveying mechanism 110a, and the second stand part 11b is equipped with a conveying mechanism 110b. On the first side 111 and the second side 112 of the universal assembly table, the conveying mechanism partially extends out of the stand, and in the middle of the universal assembly table, the conveying mechanism is basically aligned with the corresponding stand part; on the second side 112 of the universal assembly table, the conveying mechanism 110a partially extends out of the first stand part 11a, and the other side 1104 of the conveying mechanism 110a is basically aligned with the first stand part 11a. The conveying mechanism can also be roughly aligned with the stand part on the first side or the second side. The universal assembly table can be provided with multiple operating mechanism positions on the stand. On the two rack parts, there are respectively a first action mechanism position 310, a second action mechanism position 320, a first operating mechanism position 750, a second operating mechanism position 760, and a press-fitting mechanism position 710, and may also include a plurality of third operating mechanism positions 770; in the middle of the two rack parts, i.e., the docking position, there is a first action mechanism position 310 and a press-fitting mechanism position 710, part of the mounting holes of the first action mechanism position 310 are in the first rack part 11a, and the other part of the mounting holes are in the second rack part 11b; part of the mounting holes of the press-fitting mechanism position 710 are in the first rack part 11a, and the other part of the mounting holes are in the second rack part 11b. The press-fitting mechanism can be selected between three positions, which is more flexible and can meet the assembly requirements of different parts and accessories. In the corresponding area of ​​the conveying mechanism, there are two or more lifting mechanism positions 737, and the lifting mechanism positions 737 are set corresponding to the working positions. The lifting mechanism position 737 has a hole on the table plate and a corresponding space in the table for the installation of the lifting mechanism 73. Most of the lifting mechanism 73 is located below the table plate, but when lifting, at least a part of it can be located above the table plate and higher than the chain belt, and can cooperate with the workpiece rack for lifting.

[0061] If the first action mechanism is a material-taking manipulator or robot, when one first action mechanism can meet the requirements, the first action mechanism can be set at the action mechanism position in the middle. When the production capacity is met, only one can be set. If there are more feeding mechanisms, such as four, and they cannot be taken or the production capacity is insufficient, they can be increased to two, one for each of the two racks. The second action mechanism can operate on parts, such as assembling seals or acting as a tightening robot on auxiliary materials and parts. The first operating mechanism position is the main operating mechanism position, which can include multiple operating contents, and also contains different operating devices or mechanisms. The connecting member 80 is used to connect the operating device or mechanism to the connecting member, and then the operating mechanism assembly is fixed to the rack, that is, it is connected through a connecting member such as a mounting plate. This arrangement is relatively compact, and it is more convenient to connect and replace. It is suitable for when there are relatively more operating devices or mechanisms, and replacement can be completed faster, reducing replacement time. In actual use, the device or mechanism used for the operation can be assembled with the connecting parts. When replacing the workpiece or adjusting the assembly equipment, the corresponding operating mechanism components equipped with the device or mechanism can be directly replaced, that is, different operating mechanism components can be configured for standby according to the needs of different workpieces, so that the assembly equipment is more adaptable and the replacement efficiency is higher. The second operating mechanism is used for inspection, deviation correction, flipping, etc. The third operating mechanism can be adjusted according to the specific needs of the operation to operate on different parts or auxiliary materials and assemble them with the workpiece. The operating mechanism and the operation content here are only used as examples and should not be regarded as limitations on the invention of this scheme.

[0063] The assembly device may also have a connection device, see Fig.13 , Fig.13 FIG. 1 is a partial schematic diagram of another embodiment of the assembly equipment, mainly showing three universal assembly tables and connection devices. Figure 1 The main difference between the embodiments shown is that the assembly equipment has a connection device 43, which can be used to connect parts that need auxiliary connection, realize the matching transmission docking, and make the assembly equipment more flexible in increasing or decreasing the universal assembly table or changing it. For example, when the production capacity can be reduced, the functions of some universal assembly tables can be increased to reduce the beat, and the redundant universal assembly tables can be adjusted for other assembly equipment, and the original position is connected and matched with the connection device. If the assembly equipment is provided with a connection device, when the production capacity needs to be increased, the universal assembly table can be configured at the original position of the connection device, which can relatively reduce the work content of the universal assembly table of the production capacity bottleneck or increase the number of universal assembly tables of the production capacity bottleneck, thereby improving the beat.

[0064] The assembly equipment includes a first universal assembly table 301, a second universal assembly table 302, a third universal assembly table 303 and a connecting device 43. The first universal assembly table 301 includes a stand 11, specifically including two stand parts, the two stand parts are assembled and fixed by a fixing member 15, and the stand part includes a stand seat and a stand plate. The first side 111 of the first universal assembly table 301 is docked with the second universal assembly table 302. The assembly equipment is provided with a first action mechanism, a second action mechanism, a feeding mechanism 60, and a plurality of operating mechanisms on the first universal assembly table 301. Other aspects of the first universal assembly table 301 can refer to the above-mentioned universal assembly table, and will not be repeated here.

[0065] The second universal assembly table 302 includes a stand 11', which has a stand portion 11a and a conveying mechanism 110'.

[0066] The second universal assembly station 302 can be provided with a first action mechanism 31, a second action mechanism 32, a feeding mechanism 60, a pressing mechanism 71, and several operating mechanisms (not shown in the figure), and can also be equipped with a vibration feeding mechanism, an auxiliary material feeding mechanism, etc. The second side 112 of the second universal assembly station 302 cooperates with the first universal assembly station 301, and the first side 111 of the second universal assembly station 302 can cooperate with a universal assembly station, other machines or connecting devices, such as the connecting device 43. The first action mechanism 31 can deliver the parts corresponding to the position of the feeding mechanism 60 to the required position; the second universal assembly station 302 has a relatively independent control module to realize the control operation of the universal assembly station. In this universal assembly station, the operating mechanism may include a camera, a detection, a conveying device, etc. When the detection device detects a non-conforming product, the parts or auxiliary materials located in the waiting position can participate in the operation, which can reduce the waiting time required due to the detection of non-conforming products. The second universal assembly station is provided with fewer action mechanism positions, operating mechanism positions, and press-fitting mechanism positions than the first or third universal assembly station. In a specific embodiment, the second universal assembly station is provided with two groups of action mechanism positions, one or more operating mechanism positions, and one group of press-fitting mechanism positions. The first universal assembly station is provided with more than two groups of action mechanism positions, more than two groups of operating mechanism positions, and more than two groups of press-fitting mechanism positions, specifically, three to six groups of action mechanism positions, two to six groups of operating mechanism positions, and more than two groups of press-fitting mechanism positions.

[0067] The third universal assembly station 303 is similar to the first universal assembly station 301, and includes a stand 11. The stand 11 includes two stand parts and a fixing member 15 connecting the two stand parts. The stand 11 may also include three stand parts; the stand parts respectively have a stand seat and a stand plate. The assembly equipment may be provided with a first action mechanism, a second action mechanism, a feeding mechanism 60, and several operating mechanisms (not shown in the figure) on the third universal assembly station 303. On the stand 11, there are provided with more than two groups of action mechanism positions, more than two groups of operating mechanism positions, and more than two groups of press-fitting mechanism positions, specifically more than three groups of action mechanism positions, two to six groups of operating mechanism positions, and more than two groups of press-fitting mechanism positions (not shown in the figure). The second side 112 of the third universal assembly station 303 cooperates with the connecting device 43, and the first side 111 of the third universal assembly station 303 cooperates with other universal assembly stations or other machines or connecting devices.

[0068] The width L2 of the second universal assembly table 302 is half of the width of the first universal assembly table 301 and the third universal assembly table 303, and the length L4 of the conveying mechanism of the second universal assembly table 302 is half of the length L1 of the conveying mechanism of the first universal assembly table 301 and the third universal assembly table 303. The length L3 of the connecting device 43 can be the same as the length L4 of the conveying mechanism of the second universal assembly table 302, and can also be roughly the same as the length L1 of the conveying mechanism of the first universal assembly table 301 and the third universal assembly table 303. In addition, the universal assembly table can also include other forms, such as the first universal assembly table includes three rack parts, the second universal assembly table includes two rack parts, the width of the second universal assembly table is two-thirds of the width of the first universal assembly table, and the conveying mechanism can also be the same.

[0069] Such assembly equipment is more flexible in adjustment and application. When the production capacity requirement is low, such as when the mass production of automotive integrated components begins, more assembly steps can be set on a single universal assembly station, the number of universal assembly stations can be reduced, and connecting devices 43 can be set locally in the assembly equipment. When the production requirement increases, the universal assembly stations with relatively slow production rhythms can be adjusted, such as adding universal assembly stations at the connection device positions, reducing or splitting the actions or work contents of these universal assembly stations, and adjusting the assembly methods. This can reduce the action time of the bottleneck universal assembly stations and increase the output of the fixed time of the assembly equipment, that is, adding universal assembly stations at the connection device 43 positions between the universal assembly stations in the assembly equipment. The universal assembly stations are provided with wheels, which are relatively convenient to move and adjust. In addition, a locking mechanism can be added, such as a fixed reinforcement portion 18 is provided to fix it to the ground, so that it is convenient to move during adjustment, and after adjustment, it can still ensure smooth and reliable operation. The bench or bench part of the universal assembly bench is basically set up in accordance with standards to facilitate adjustment. The assembly equipment is relatively flexible, and the production capacity rhythm is adjustable and fast. It can be used for the assembly of different similar integrated components. It is more convenient than conventional assembly equipment and can adapt to the needs of business adjustments. When adjusting the production line, it can reduce waste, realize replacement and adjustment more quickly, improve production efficiency and reduce waste of resources.

[0070] Set a waiting position and limit mechanism in front of the working position of the universal assembly table. Fig.16 , Fig.16It is a partial schematic diagram of the docking position of two universal assembly tables in one embodiment of an assembly device. The assembly device includes a first universal assembly table 401 and a second universal assembly table 402. The second universal assembly table 402 is provided with a proximity sensing element 79 on the first universal assembly table 401, and the proximity sensing element 79 is connected to its control module through a wiring harness. In front of the first working position 210, a limiting mechanism 78 is also provided to cooperate with the limiting of the workpiece rack in the waiting position, and another proximity sensing element 79 is provided to sense the situation of the workpiece rack to the working position. In the working position 210, there is a proximity sensing element 79 and a limiting mechanism 78 (not shown in the figure) that cooperate with the working position 210. In front of the proximity sensing element 79, a waiting position 240 is also provided, and has a proximity sensing element 79 and a limiting mechanism 78. The proximity sensing element 79 can respond to the workpiece rack coming from the first universal assembly table, and send a signal to the control module, or enable the control module to obtain corresponding sensing information. When there is a workpiece rack 21 at the working position 210, the limiting mechanism 78 corresponding to the waiting position is protruded to block the workpiece rack from being transferred to the working position, and wait at the waiting position 240; until the workpiece operation on the workpiece rack of the working position 210 is completed and transferred, the limiting mechanism 78 of the waiting position is actuated, and no longer blocks the workpiece rack 21, so that the workpiece rack together with the workpiece thereon reaches the working position 210, and the limiting mechanism 78 corresponding to the working position blocks the workpiece rack, and lifts and fixes it through the lifting mechanism 73 to carry out the operation content of the working position. That is, the universal assembly table is provided with a proximity sensing element 79 and a limiting mechanism 78 in front of its first working position. The proximity sensing element 79 can be located near the position of the previous universal assembly table or behind the last working position of the previous universal assembly table. The proximity sensing element 79 is connected to the control module for communication. The limiting mechanism 78 is arranged in front of the working position of the universal assembly table, or can be arranged behind the working position of the previous universal assembly table of the universal assembly table. The front and back here refer to the conveying direction of the workpiece rack. The limiting mechanism can be in the limiting state by default, and will no longer limit when receiving the control signal, or the action of the limiting mechanism can be realized by turning on and off the power of the control module. The waiting position can be set in front of the working position of the universal assembly table, and the limiting mechanism of the waiting position is controlled by the control module of the universal assembly table. It can also be set behind the working position of the universal assembly table, and the universal assembly table needs to be connected to the next universal assembly table for communication. It can also be set between two racks, such as matching the docking position.

[0071] The action mechanism can be a robotic arm that can perform operations such as grasping, moving, and detecting. The operating mechanism can complete actions including pressing, tightening, locking, detecting, and oiling. Specifically, it may include more than two workstations, and certain operations are performed at each workstation. The workstations can be configured in multiple ways for selection, and it may also include transmission between workstations.

[0072] A connecting plate 83 can be provided between two adjacent universal assembly tables or between a universal assembly table and an adjacent conveying mechanism on the basis of being connected. The connecting plate can be provided between the racks of adjacent universal assembly tables or between two adjacent conveying mechanisms.

[0073] Each universal assembly table is provided with a control module, and the assembly equipment has a control system. The control system is communicatively connected with the control module of the universal assembly table. The control module of the universal assembly table can exchange information with the control system, and the control module of the universal assembly table can also exchange information with adjacent control modules. The operation of the action mechanism and the operating mechanism arranged on the universal assembly table can be controlled by the control module, thereby reducing the difficulty of debugging the control system.
