[0055] Embodiment:

[0056] As shown in Figure 1 and Figure 2 , an equipment for automatic assembly of armature and moving spring includes a plurality of moving forward tool clamps 1, and the plurality of tool clamps 1 form a conveying line; different tool clamps 1 serve as different workstations, wherein the tool clamp 1 includes a table plate 105, and the table plate 105 has two small workstations, namely a front workstation 107 and a rear workstation 108; each workstation only selects one small workstation to work, for example, when rivets are installed, the front workstation 107 is used, and when insulation sheets are installed, the rear workstation 108 is used.

[0057] In the present embodiment, for the convenience of description, as shown in Figure 5 , the workstation corresponding to the feeding assembly 2, namely the front workstation 107, is referred to as workstation A, the workstation corresponding to the rivet installation assembly 3, namely the front workstation 107, is referred to as workstation B, the workstation corresponding to the turnover assembly 4, namely the front workstation 107, is referred to as workstation C, on which workstation, the turnover assembly 4 turns over the product on the front workstation 107 and places it on the rear workstation 108 of the same tool clamp, the workstation corresponding to the insulation sheet installation assembly 5, namely the rear workstation 108, is referred to as workstation D, the workstation corresponding to the armature installation assembly 6, namely the rear workstation 108, is referred to as workstation E, the workstation corresponding to the rivet pressing assembly 7, namely the rear workstation 108, is referred to as workstation F, and the workstation corresponding to the spring sheet cutting assembly 8, namely the rear workstation 108, is referred to as workstation G.

[0058] Further comprising:

[0059] The feeding assembly 2 is used for placing a product (a moving spring sheet) on the starting tool clamp 1 of the conveying line;

[0060] The rivet installation assembly 3 is used for placing a rivet on the moving spring sheet on the tool clamp 1; wherein the moving spring sheet has two rivet holes, and the rivet is placed in the two rivet holes;

[0061] The turnover assembly 4 is used for turning over the moving spring sheet by 180°;

[0062] The insulation sheet installation assembly 5 is used for placing an insulation sheet on the moving spring sheet;

[0063] upper armature assembly 6 for placing the armature on the insulation sheet;

[0064] rivet assembly 7 for riveting the rivet;

[0065] spring cutting assembly 8 for cutting the excess material;

[0066] finished product conveyor 9 for conveying the finished product.

[0067] As shown in the drawings, Figure 2 the feeding assembly 2 includes a feeding line 201, a mechanical hand 202, a starting station 203, and a feeding clamp (not shown). The feeding line 201 conveys the products in a row. The mechanical hand 202 takes the products from the feeding line 201. Since the products on the feeding line are turned over, they need to be turned over when the rivets are installed. Therefore, the mechanical hand is turned over by 180° and placed on the starting station 203, so that the products on the starting station 203 are in the required direction for installing the rivets. After the feeding clamp takes the products on the starting station 203, it moves along the feeding track 204, and then places the products on the station A. After transmission, the products are placed on the station B by the mechanical hand. The feeding track 204 is provided with up-down and left-right functions, so that the feeding clamp can take the products from the starting station 203 downward, and then move rightward to the conveying line and place the products downward.

[0068] As shown in the drawings, Figure 3 the tool clamp 1 includes a base plate 105 and a push rod 102 for pushing the base plate 5 forward. The two ends of the base plate 105 in the forward direction are each fixed with a spacing rod 106. The spacing rods 106 of adjacent two base plates 105 abut each other, and the lengths of the spacing rods 106 are the same. This structure makes the distance between every two base plates 105 the same.

[0069] When the push rod 102 is pushed once, the base plate 105 is pushed forward by a certain distance, which is the total length of one base plate 105 and two spacing rods 106 on both sides. When the station completes receiving the products, the push rod 102 pushes the next base plate 105 to the position of the current station, that is, the position of the current base plate 105, so that the current base plate 105 is pushed to the next station. After the push rod 102 completes the pushing, it automatically retreats to prepare for the next pushing action. In this embodiment, the power of the base plate comes from the push rod 102. One power source of the push rod 102 drives the movement of the entire conveying line. In addition, the setting of the spacing rods 106 ensures the fixed distance between every two base plates 105 and the accuracy of the arrival position of the station, replaces the original conveying belt conveying structure, and avoids the phenomenon of inaccurate positioning.

[0070] Further, as shown in the drawings, Figure 4As shown, a connecting rod 104 is fixed to the bottom of the platform 105, and a conveyor track 103 is provided below the platform 105. Under the power of the actuating rod 102, the connecting rod 104 drives the platform 105 to move forward along the conveyor track 103. It is arranged in a ring (only a section is shown in the figure). The connecting rod 104 always moves on the ring-shaped conveyor track 103, forming a cycle that does not occupy space and does not require manual handling. After the entire process is completed, it gradually returns to the starting position using the power of the actuating rod.

[0071] like Figure 4 As shown, the lever 102 includes a lever body 1021, a lever head 1022, and a lever bottom 1023. The lever body 1021 is inclined, and the lever head 1022 is fixed to the upper end of the lever body 1021. The lever head 1022 and the lever body 1021 are connected at an obtuse angle, and the inner side of the lever head 1022 is vertically arranged so that the lever head 1022 can hook onto the platform 105. The lever bottom 1023 is fixed to the lower end of the lever body 1021 and is slidably connected to the lever track 101. The lever bottom 1023 is connected to a driving member to drive the lever 102 to reciprocate along the lever track 101. The bottom 1023 of the lever is equipped with a rotating shaft 1204 and a rotational power source (not shown). When the lever 105 is in position, the rotational power source drives the rotating shaft 1204 to rotate, causing the free end of the bottom 1023 to tilt upwards and the lever head 1022 to rotate downwards. The lever head 1022 is lower than the height of the lever 105, so that the lever 102 will not interfere with the next lever 105 when it moves. That is, the lever head 1022 descends, passes around the next lever 105, and then rises back to its original position before levering the lever 105 again. To ensure the smooth movement of the lever 102, the bottom 1023 can rotate to allow the lever head 1022 to descend, and it can also move back and forth on the lever track 101.

[0072] The lever 102 not only provides power to each worktable 105 during processing, but also provides power to return an empty worktable 105.

[0073] like Figure 6As shown, the upper rivet assembly 3 includes a rivet bin 301 and an upper rivet runner 302. Below the outlet of the upper rivet runner 302, there are a first transfer chuck 303 and a second transfer chuck 304. Among them, the structures of the first transfer chuck 303 and the second transfer chuck 304 are the same. Taking the first transfer chuck 303 as an example, the first transfer chuck 303 includes two identical clamping plates. On the opposite surfaces of the two clamping plates, there is a semi-groove respectively. The two semi-grooves form a clamping groove 305. The two clamping plates are provided with their own power sources, and the power sources drive the two clamping plates to separate or merge. When merged, they clamp the rivet, and when separated, they release the rivet. At the same time, the operating principle of the second transfer chuck 304 is the same as that of the first transfer chuck 303. In addition, the first transfer chuck 303 and the second transfer chuck 304 can be separated from each other. When separated, as Figure 7 shown, the separation action can be realized by structures such as a cylinder, which will not be elaborated here.

[0074] After the first transfer chuck 303 and the second transfer chuck 3 have each clamped a rivet at the outlet of the upper rivet runner 302, they each move a certain displacement, so that the two rivets are separated by a certain gap; that is: after the first transfer chuck 303 and the second transfer chuck 304 clamp the rivets, the second transfer chuck 304 advances ( Figure 7 it is moving right in the figure) a distance, and the first transfer chuck 303 advances b distance, b < a. After stopping, the distance between the two rivets is b - a. The separated distance is as Figure 7 shown in the figure. In this embodiment, two rivets (two rivets are required for one product) are output side by side. The first transfer chuck 303 and the second transfer chuck 304 are used to realize the operations of transfer and separation. The separated distance adapts to the distance between the positions of the two rivets on the product, which can ensure the distance between the two rivets from the source. Then, it can be directly sent to the product without further separation on the product, saving the residence time on the conveyor line and accelerating the working speed.

[0075] The upper rivet assembly 3 further includes two rivet feeding jaws 307. After the rivet feeding jaws 307 pick up the rivets from the first transfer chuck 303 and the second transfer chuck 304, they move to the tooling fixture 1 and place the rivets on the product. As Figure 7 shown, the first transfer chuck 303 and the second transfer chuck 304 separate the two rivets by a certain distance, and the rivet feeding jaws 307 send the rivets to the platen 105. Among them, the two rivet feeding jaws 307 adopt thumb cylinders, and the conveying plate 306 can descend, ascend, and move left and right to transport the rivets to the platen 105, that is, the station B. This is the prior art and will not be elaborated here.

[0076] After the station B is completed, under the action of the toggling rod 102, the platen 105 at the station B moves to the next station, that is, the station C. At the station C, there is a flipping assembly 4 for flipping the moving reed 18 through 0°. AsFigure 8 As shown, the turnover assembly 4 includes a seat plate 41, a lower supporting plate 42 and an upper clamping plate 43 are arranged on the seat plate 41, and the lower supporting plate 42, the upper clamping plate 43 and the seat plate 41 adopt a slide table air cylinder form. When the air cylinder works, the lower supporting plate 42 and the upper clamping plate 43 are combined to clamp the product. After the product is turned over 180° by using a rotary air cylinder 44 arranged at the rear end, the product is placed on another station of the table plate 105. The end of the upper clamping plate 43 is provided with a folding lug 45, which ensures the stability of clamping the product.

[0077] After the turnover is completed, under the action of the shifting lever 102, the table plate advances to the next station, i.e. station D, and an upper insulating sheet assembly 5 is arranged on the upper insulating sheet. The upper insulating sheet assembly 5 includes an insulating sheet feeding channel 501, an insulating sheet feeding track 503 and an insulating sheet feeding clamp jaw 502. The insulating sheet feeding clamp jaw 502 clamps an insulating sheet on the insulating sheet feeding channel 501, and the insulating sheet feeding clamp jaw 502 moves up, down, left and right on the insulating sheet feeding track 503 to place the insulating sheet on the moving spring sheet. The insulating sheet itself has two holes corresponding to two rivets, and the rivets are in interference fit with the insulating sheet.

[0078] The table plate 105 continues to move to station E, and an upper armature assembly 6 includes an armature feeding channel 601, an armature feeding track 603 and an armature feeding clamp jaw 602. The armature feeding clamp jaw 602 clamps an armature on the armature feeding channel 601, and the armature feeding clamp jaw 602 moves up, down, left and right on the armature feeding track 603 to place the armature on the product. The armature itself has two holes corresponding to two rivets.

[0079] A rivet pressing assembly 7 is arranged at station E, which adopts an air cylinder and a pressing plate to press the rivet. After the rivet is delivered, it is directly pressed to ensure that the insulating sheet and the armature will not be separated from the product.

[0080] The table plate 105 continues to move to station G to perform a cutting operation. A spring sheet cutting assembly 8 includes a first clamp jaw 801 and a second clamp jaw 802 which move synchronously, the first clamp jaw 801 and the second clamp jaw 802 are arranged on an electric cylinder 806 to move synchronously, and the spring sheet cutting assembly 8 further includes a cutting plate 803 and a cutting machine 805. The second clamp jaw 802 takes the product from the work fixture 1 on the conveying line and places it on the cutting plate 803. The cutting plate 803 moves along a cutting guide rail 804 into the cutting machine 805 to perform a cutting operation. After the cutting operation, the cutting plate 803 is reset. The first clamp jaw 801 takes the product from the cutting plate 803 and places it on a finished product conveyor 9.

[0083] 2、Mechanical hand 202 of feeding assembly 2 flips the product on product line 201 by 180° and places it on starting station 203. After the feeding gripper clamps the product on starting station 203, it moves along feeding track 204 to the top of tooling clamp 1, and then places the product on station A;

[0084] 3、After feeding is completed, the next platen 105 is moved to the position of station A by toggle lever 102, and the current platen 105 is pushed to the next station, i.e. the transition station. When the next platen 105 completes feeding and toggle lever moves another platen again, the current platen, i.e. the first platen, is clamped on station B (mechanical hand not shown);

[0085] 4、After first transfer chuck 303 and second transfer chuck 304 on station B each clamps a rivet at the outlet of rivet feeding channel 302, they each move a certain displacement, so that the two rivets are separated by a certain gap. Rivet feeding gripper 307 clamps the rivets from first transfer chuck 303 and second transfer chuck 304, and then moves to tooling clamp 1 to place the rivets on the product.
