Description

Technical Field

[0001] This application relates to the technical field of thermostat processing. Specifically, it relates to an assembly device for the static contact component of a high-current thermostat. Background Art

[0002] A high-current thermostat is a type of thermostat used to control the operation of equipment to achieve an ideal temperature and is widely used in heating equipment such as electric water heaters, electric water faucets, and instant hot water dispensers. The internal structure of some high-current thermostats is as Figure 20 described, including two terminal blocks 1', a static contact component 2', a moving contact component 3', and a push rod 4'. Among them, referring to Figure 21 , the static contact component 2' includes a semi-circular fixed contact piece 90, a mounting post 91 inserted through the fixed contact piece 90, and a sleeve 92 sleeved on the mounting post 91. The sleeve 92 is fixed to the mounting post 91 by multi-press riveting (forming an inwardly concave press riveting point 93 to clamp the mounting post 91). One end of the mounting post 91 is provided with a column cap 94, and the column cap 94 and the sleeve 92 are located on opposite sides of the fixed contact piece 90 to axially limit the mounting post 91.

[0003] In fact, the static contact component 2' is first assembled as a whole and then assembled with other components of the high-current thermostat. Moreover, after the static contact component 2' is assembled, it is necessary to ensure that the mounting post 91 can rotate relative to the fixed contact piece 90. The existing assembly method for the static contact component 2' is generally to manually insert the mounting post 91 into the fixed contact piece 90, manually sleeve the sleeve 92 onto the mounting post 91, and then send it to a riveting device to press-rivet the sleeve 92. After a batch of static contact components 2' are assembled, they are manually sampled to detect whether the mounting post 91 can rotate relative to the fixed contact piece 90. This method has low production efficiency and high labor costs. In addition, the sampling method after batch assembly cannot fully identify defective static contact components 2', and it is easy for defective static contact components 2' to be used in the subsequent assembly of high-current thermostats, resulting in a high defective rate.

[0004] Therefore, the existing technology needs to be improved and enhanced. Summary of the Invention

[0075] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance

[0076] Please refer to Figures 1 - 2 , a large-current thermostat static contact component assembly device in some embodiments of the present application, including a machine table 1, a circular turntable 2 arranged on the top of the machine table 1, a plurality of positioning jigs 3 arranged at equal intervals on the edge of the circular turntable 2, a plurality of assembly mechanisms 4 and a main control device 5. The plurality of assembly mechanisms 4 include a first feeding mechanism 6, a first detection mechanism 7, a second feeding mechanism 8, a second detection mechanism 9, a third feeding mechanism 10, a third detection mechanism 11, a riveting mechanism 12 and a blanking mechanism 13 arranged in sequence around the circular turntable 2

[0077] The circular turntable 2 is used to drive each positioning jig 3 to rotate to align with each assembly mechanism 4 in sequence

[0078] The first feeding mechanism 6 is used to position and place the mounting column 91 in the positioning fixture 3; the first detection mechanism 7 is used to detect whether the mounting column 91 is placed in the positioning fixture 3;

[0079] The second feeding mechanism 8 is used to put the fixed contact 90 into the positioning fixture 3 and sleeve the fixed contact 90 onto the mounting column 91; the second detection mechanism 9 is used to detect whether the fixed contact 90 is placed in the positioning fixture 3;

[0080] The third feeding mechanism 10 is used to put the sleeve 92 into the positioning fixture 3 and sleeve the sleeve 92 onto the mounting column 91; the third detection mechanism 11 is used to detect whether the sleeve 92 is placed in the positioning fixture 3;

[0081] The riveting mechanism 12 is used to perform multi-point riveting on the sleeve 92 so that the sleeve 92 is fixed on the mounting column 91 to obtain the static contact component;

[0082] The blanking mechanism 13 is used to take out the assembled static contact component from the positioning fixture 3, detect the rotatability of the mounting column 91 (i.e., detect whether the mounting column 91 can rotate relative to the fixed contact 90), and then classify and blank the static contact component according to the rotatability detection result;

[0083] The main control device 5 is used to control the circular turntable 2 and each assembly mechanism 4 to work.

[0084] This assembly equipment drives the positioning fixture 3 to align with each assembly mechanism 4 in turn through the circular turntable 2 to gradually complete the assembly of the static contact component. After detecting the rotatability of the mounting column 91 during blanking, the static contact component is classified and blanked according to the rotatability detection result, realizing the automation of the whole process of assembling the static contact component and the on-line detection of each static contact component, improving the assembly efficiency of the static contact component, reducing the labor cost, and reducing the risk of using defective static contact components.

[0085] Specifically, this assembly equipment completes the following assembly process under the control of the main control device 5:

[0086] First, the first feeding mechanism 6 positions and places the mounting column 91 in the positioning fixture 3, and the positioning fixture 3 rotates to the first detection mechanism 7 for detection. If it is detected that the mounting column 91 is not placed in the positioning fixture 3, the positioning fixture 3 will not be processed at each subsequent assembly mechanism 4 until the mounting column 91 is placed again when the positioning fixture 3 is aligned with the first feeding mechanism 6. If it is detected that the mounting column 91 is placed in the positioning fixture 3, when the positioning fixture 3 rotates to the second feeding mechanism 8, the second feeding mechanism 8 places the fixed contact piece 90 into the positioning fixture 3. Then, the positioning fixture 3 rotates to the second detection mechanism 9 for detection. If it is detected that the fixed contact piece 90 is not placed in the positioning fixture 3, the positioning fixture 3 will not be processed at each subsequent assembly mechanism 4 until the fixed contact piece 90 is placed again when the positioning fixture 3 is aligned with the second feeding mechanism 8. If it is detected that the fixed contact piece 90 is placed in the positioning fixture 3, when the positioning fixture 3 rotates to the third feeding mechanism 10, the third feeding mechanism 10 places the sleeve 92 into the positioning fixture 3. Then, the positioning fixture 3 rotates to the third detection mechanism 11 for detection. If it is detected that the sleeve 92 is not placed in the positioning fixture 3, the positioning fixture 3 will not be processed at each subsequent assembly mechanism 4 until the sleeve 92 is placed again when the positioning fixture 3 is aligned with the third feeding mechanism 10. If it is detected that the sleeve 92 is placed in the positioning fixture 3, when the positioning fixture 3 rotates to the riveting mechanism 12, multi-point riveting is performed on the sleeve 92. Then, when the positioning fixture 3 rotates to the unloading mechanism 13, the unloading mechanism 13 takes out the static contact component from the positioning fixture 3. After the unloading mechanism 13 takes out the static contact component, the rotatability of the mounting column 91 is first detected, and then the static contact components are classified and unloaded according to the rotatability detection results.

[0087] In some preferred embodiments, see Figure 17 , Figure 18 , the unloading mechanism 13 includes an unloading two-finger jaw 15, an unloading driving mechanism 16 for driving the movement of the unloading two-finger jaw 15, a classification storage structure 17, a blowing pipe 18, and a photoelectric proximity sensor 19. The unloading two-finger jaw 15 takes out the static contact component from the positioning fixture 3 by clamping the sleeve 92. The photoelectric proximity sensor 19 is connected to the unloading two-finger jaw 15. The unloading driving mechanism 16 can drive the unloading two-finger jaw 15 to move to the blowing station so that the fixed contact piece 90 of the static contact component is aligned with the outlet of the blowing pipe 18 (that is, the position where the unloading two-finger jaw 15 is located when the fixed contact piece 90 is aligned with the outlet of the blowing pipe 18 is the blowing station, as shown in Figure 18 ), and the blowing pipe 18 is used to eject air flow to push the fixed contact piece 90 to rotate so as to trigger the photoelectric proximity sensor 19. The classification storage structure 17 is used to classify and store the static contact components.

[0088] The jet air flow is used to drive the fixed contact piece 90 to rotate, thereby triggering the photoelectric proximity sensor 19. According to the triggering situation of the photoelectric proximity sensor 19, it can be effectively judged whether the mounting column 91 can rotate relative to the fixed contact piece 90, and the detection structure and detection logic are simple and easy to implement.

[0089] Specifically, the initial positions of the photoelectric proximity sensor 19 and the fixed contact piece 90 of the removed static contact component are misaligned with each other, so that the photoelectric proximity sensor 19 will not be triggered when the static contact component is removed. If the mounting column 91 can rotate relative to the fixed contact piece 90, the fixed contact piece 90 will rotate under the drive of the air flow, and then trigger the photoelectric proximity sensor 19. Therefore, the main control device 5 can judge whether the mounting column 91 can rotate relative to the fixed contact piece 90 according to whether the photoelectric proximity sensor 19 is triggered after the static contact component moves to the blowing station, so as to determine whether the static contact component is a good product or a defective product, and control the blanking mechanism 13 to store the good products and defective products separately.

[0090] The traditional method for detecting the rotatability of the mounting column 91 is to transfer it to a dedicated detection station after blanking, use dedicated detection equipment for detection, and then store the static contact components separately according to the detection results. The work continuity is poor, the steps are complicated, the efficiency is low, and dedicated detection stations and detection equipment need to be equipped, resulting in high implementation costs. Here, by simply adding a blow pipe 18 and a photoelectric proximity sensor 19 to the blanking mechanism 13, the rotatability of the mounting column 91 can be reliably detected before blanking, and then classified blanking can be achieved. The work continuity is good, the efficiency is higher, and no dedicated detection stations and detection equipment need to be additionally equipped, resulting in low implementation costs.

[0091] In some possible implementation manners, see Figure 17 、 Figure 18 , the blanking two-finger gripper 15 includes a gripper cylinder 1501 and two L-shaped gripper fingers 1502. The photoelectric proximity sensor 19 is arranged at the bottom of the gripper cylinder 1501 and between the two L-shaped gripper fingers 1502, and the photoelectric proximity sensor 19 is offset along the normal direction of the moving plane of the L-shaped gripper fingers 1502 (i.e., Figure 18 the paper plane). Thus, after the two L-shaped gripper fingers 1502 grip the static contact component, the initial position of the fixed contact piece 90 is misaligned with the photoelectric proximity sensor 19, and when the fixed contact piece 90 rotates, it can rotate to directly below the photoelectric proximity sensor 19, thereby triggering the photoelectric proximity sensor 19. Since the size of the static contact component is small, if the photoelectric proximity sensor 19 is arranged on the side of the gripper cylinder 1501, it is difficult to ensure that the fixed contact piece 90 can rotate to the position where it triggers the photoelectric proximity sensor 19. Therefore, arranging the photoelectric proximity sensor 19 between the two L-shaped gripper fingers 1502 and offsetting it can solve this problem.

[0092] The unloading drive mechanism 16 may be a robotic arm or a two-axis drive device, but is not limited thereto. Figure 17 In the figure, the unloading drive mechanism 16 is a two-axis drive device, which can drive the two-finger unloading clamp 15 to move back and forth and up and down along the radial direction of the circular turntable 2; the two-axis drive device can be a cylinder-driven two-axis drive device or a screw-driven two-axis drive device, but is not limited to this.

[0093] Among them, the blowing pipe 18 preferably adopts a flexible metal conduit, so that the position and direction of the outlet of the blowing pipe 18 can be adjusted according to actual needs to better adapt to the initial position of the fixed contact piece 90, ensuring that the fixed contact piece 90 can be subjected to greater wind force when entering the blowing station at the initial position.

[0094] Further, see Figure 17 The classification storage structure 17 includes a waste box 1701, a slide 1702 and a slide drive device 1703. The slide drive device 1703 is used to drive the slide 1702 to move to above the waste box 1701 or leave above the waste box 1701, and the two-finger unloading clamp 15 performs unloading above the waste box 1701. The slide 1702 is used to transport the qualified static contact assembly (that is, the static contact assembly whose mounting column 91 can rotate relative to the fixed contact piece 90) dropped from the two-finger unloading clamp 15 to an external transmission device (such as a conveyor belt) when moving to above the waste box 1701. The waste box 1701 is used to store unqualified static contact assemblies (that is, the static contact assemblies whose mounting column 91 cannot rotate relative to the fixed contact piece 90) dropped from the two-finger unloading clamp 15.

[0095] The slide drive device 1703 may be a pneumatic cylinder, a hydraulic cylinder, an electric telescopic rod or a linear motor, but is not limited thereto.

[0096] Specifically, see Figure 4 、 Figure 5 The top of the positioning fixture 3 is provided with a positioning groove 301 adapted to the fixed contact piece 90, and the bottom of the positioning groove 301 is provided with a positioning hole 302 adapted to the column cap 94 of the mounting column 91;

[0097] The first loading mechanism 6 is used to insert the mounting column 91 into the positioning hole 302 with the column cap facing downward;

[0098] The second loading mechanism 8 is used to place the fixed contact piece 90 into the positioning groove 301 and to insert the fixed contact piece 90 into the mounting column 91 .

[0099] The fixed contact piece 90 and the mounting post 91 can be reliably positioned by the positioning groove 301 and the positioning hole 302 so as to be accurately aligned with each assembly mechanism 4, thereby ensuring reliable execution of each assembly step.

[0100] Specifically, see Figure 7, the first detection mechanism 7 includes a first detection seat 701 located above the positioning fixture 3 and a first pair of light sensors 702. The first detection seat 701 is provided with a first through hole 703 through which the mounting column 91 passes when moving with the positioning fixture 3. The emitter and receiver of the first pair of light sensors 702 are relatively arranged on both sides of the first through hole 703. When the mounting column 91 passes through the first through hole 703, it can trigger the first pair of light sensors 702.

[0101] When the mounting column 91 passes through the first through hole 703, it will block the light beam emitted by the emitter of the first pair of light sensors 702, so that the receiver cannot receive this light beam, thus triggering the first pair of light sensors 702; if the mounting column 91 is not placed in the positioning fixture 3, when the positioning fixture 3 moves to the first detection mechanism 7, the first pair of light sensors 702 will not be triggered. Therefore, the main control device 5 can judge whether the mounting column 91 is placed in the positioning fixture 3 according to the triggering situation of the first pair of light sensors 702. The structure of this first detection mechanism 7 is simple and has high reliability.

[0102] Preferably, the height of the first detection seat 701 is adjustable, so that the height of the first detection seat 701 can be adjusted according to actual needs to adapt to mounting columns 91 of different heights and improve applicability. There are various ways to achieve the adjustable height of the first detection seat 701. For example, the first detection seat 701 can be slidably arranged on a vertically extending slide rail and locked by a locking screw, but it is not limited to this.

[0103] In some preferred embodiments, see Figure 4 、 Figure 5 , a detection through hole 303 is further opened at the bottom of the groove of the positioning groove 301. The detection through hole 303 vertically penetrates the upper and lower sides of the positioning fixture 3;

[0104] See Figure 9 , the second detection mechanism 9 includes a second detection seat 901 and a second pair of light sensors 902. The second detection seat 901 is provided with a second through hole 903 through which the positioning fixture 3 passes when moving. The emitter and receiver of the second pair of light sensors 902 are relatively arranged on the upper and lower sides of the second through hole 903. The detection through hole 303 can move with the positioning fixture 3 to a position where it is vertically aligned with the emitter and receiver of the second pair of light sensors 902.

[0105] When the positioning fixture 3 moves to the second detection mechanism 9, if the fixed contact piece 90 is not placed in the positioning fixture 3, the detection through hole 303 is unobstructed. At this time, the light beam emitted by the emitter of the second opposed sensor 902 can pass through the detection through hole 303 and be received by the receiver of the second opposed sensor 902. Thus, the second opposed sensor 902 is in an untriggered state; if the fixed contact piece 90 is placed in the positioning fixture 3, the detection through hole 303 is blocked by the fixed contact piece 90, causing the receiver of the second opposed sensor 902 to not receive the light beam. Thus, the second opposed sensor 902 is in a triggered state; therefore, the main control device 5 can determine whether the fixed contact piece 90 is placed in the positioning fixture 3 according to the triggering condition of the second opposed sensor 902. The structure and detection logic of this second detection mechanism 9 are simple and easy to implement.

[0106] Preferably, the height of the second detection seat 901 is adjustable, so that the height of the second detection seat 901 can be adjusted according to actual needs to adapt to the positioning fixture 3 with different installation heights, thereby improving applicability. There are various ways to achieve the adjustable height of the second detection seat 901. For example, the second detection seat 901 can be slidably arranged on a vertically extending slide rail and locked by a locking screw, but it is not limited to this.

[0107] In some preferred embodiments, see Figure 5 , the positioning hole 302 penetrates through the bottom of the positioning fixture 3, and a slide bar 304 is slidably inserted through the positioning hole 302, and the lower end of the slide bar 304 extends out of the bottom of the positioning fixture 3;

[0108] See Figure 12 , the third detection mechanism 11 includes a third detection seat 1101 located above the positioning fixture 3 and capable of moving up and down, a first driving device 1102 for driving the third detection seat 1101 to move up and down, and a proximity switch 1103 arranged on the third detection seat 1101. The proximity switch 1103 has a trigger rod 1104 extending downward. The positioning hole 302 can move with the positioning fixture 3 to a position aligned with the lower end of the trigger rod 1104. The mounting post 91 and the slide bar 304 can be pushed downward by the trigger rod 1104 when the third detection seat 1101 moves downward until the sleeve 92 abuts against the trigger rod 1104 and triggers the proximity switch 1103.

[0109] When the positioning fixture 3 moves to the third detection mechanism 11, the third detection seat 1101 moves downward, and the trigger rod 1104 pushes the mounting column 91 and the sliding rod 304 downward. If a sleeve 92 is placed in the positioning fixture 3, when the mounting column 91 moves downward until its top is flush with the top of the sleeve 92, the trigger rod 1104 abuts against the sleeve 92 and thus cannot move downward further, while the third detection seat 1101 continues to move downward. Therefore, the trigger rod 1104 moves upward relative to the third detection seat 1101 to trigger the proximity switch 1103. If the sleeve 92 is not placed in the positioning fixture 3, the trigger rod 1104 cannot trigger the proximity switch 1103 even when it moves downward to the limit position (this limit position is determined by adjusting the stroke of the first driving device 1102). Therefore, the main control device 5 can determine whether the sleeve 92 is placed in the positioning fixture 3 according to the triggering situation of the proximity switch 1103. The structure of the third detection mechanism 11 is simple and has good reliability.

[0110] Among them, the first driving device 1102 can be a cylinder, a hydraulic cylinder, an electric telescopic rod or a linear motor, etc., but is not limited thereto.

[0111] Specifically, see Figures 13 - 16 , the riveting mechanism 12 includes an upper pushing component 1201, a riveting positioning component 1202 and a riveting actuating component 1203;

[0112] The upper pushing component 1201 is located below the positioning fixture 3 and is used to push the sliding rod 304 upward so that the mounting column 91 moves upward;

[0113] The riveting positioning component 1202 includes a riveting female block 1204 that can move up and down, a second driving device 1205 that drives the riveting female block 1204 to move up and down, a plurality of pressing blocks 1206 slidably arranged at the bottom of the riveting female block 1204, and a positioning pressing rod 1207 that penetrates through the riveting female block 1204 and extends vertically downward from the bottom of the riveting female block 1204; the pressing blocks 1206 are evenly arranged around the positioning pressing rod 1207 and can reciprocate radially along the positioning pressing rod 1207. A pressing needle 1208 is arranged at the first end of the pressing block 1206 close to the positioning pressing rod 1207 and located below the lower end of the positioning pressing rod 1207; the positioning pressing rod 1207 is used to press the sleeve 92 against the fixed contact piece 90;

[0114] The riveting actuating component 1203 is used to drive each pressing block 1206 to move, so as to rivet the sleeve 92 through the pressing needle 1208.

[0115] When the positioning fixture 3 moves to the riveting mechanism 12, the upper pushing component 1201 pushes the sliding rod 304 upward so that the mounting column 91 moves upward (since when detecting in the third detection mechanism 11, the trigger rod 1104 pushes the mounting column 91 downward, therefore, when riveting, the mounting column 91 needs to move upward to the correct position. At this correct position, the upper end of the mounting column 91 extends out of the upper end of the sleeve 92, asFigure 21 As shown), at the same time, the riveting female block 1204 moves downward until the positioning pressure rod 1207 presses the sleeve 92 tightly against the fixed contact piece 90 to prevent the sleeve 92 from shifting during the riveting process and ensure the accurate connection position of the sleeve 92 on the mounting post 91 (thus ensuring that the sleeve 92 and the column cap 94 do not clamp the fixed contact piece 90 and cause the mounting post 91 to be non-rotatable, and also avoiding the distance between the sleeve 92 and the column cap 94 being too large and causing the mounting post 91 to be too loose). Then, the riveting actuating component 1203 drives each pressing block 1206 to move inward, and the pressing needle 1208 presses inwardly recessed riveting points 93 on the sleeve 92, thereby fixing the sleeve 92 on the mounting post 91.

[0116] Among them, the number of the pressing blocks 1206 can be adjusted according to actual needs. For example, it can be 6 - 8, but not limited to this.

[0117] Preferably, as shown in Figure 16 , a positioning notch 1209 adapted to the mounting post 91 is provided at the center of the lower end face of the positioning pressure rod 1207. The positioning notch 1209 is used for the upper end of the mounting post 91 to be inserted therein to cooperate with the upward pushing component 1201 to position the axial position of the mounting post 91, so that there is a gap between the upper surface of the column cap 94 of the mounting post 91 and the lower surface of the fixed contact piece 90.

[0118] There is a gap between the upper surface of the column cap 94 of the mounting post 91 and the lower surface of the fixed contact piece 90, that is, the distance between the lower end of the sleeve 92 and the upper surface of the column cap 94 is greater than the thickness of the fixed contact piece 90, thereby preventing the sleeve 92 and the column cap 94 from clamping the fixed contact piece 90 and causing the mounting post 91 to be non-rotatable.

[0119] Among them, the size of the gap left between the upper surface of the column cap 94 of the mounting post 91 and the lower surface of the fixed contact piece 90 can be set according to actual needs. Actually, it can be achieved by adjusting the depth of the positioning notch 1209. For example, the depth of the positioning notch 1209 can be set to the standard protruding length L of the upper end of the mounting post 91 protruding from the upper end of the sleeve 92 (see Figure 21 , this standard protruding length is the designed length. At this standard protruding length, the distance between the upper surface of the column cap 94 and the lower end of the sleeve 92 is slightly greater than the thickness of the fixed contact piece 90. While ensuring that the mounting post 91 can rotate smoothly, the mounting post 91 will not be too loose); at this time, when the lower end of the positioning pressure rod 1207 presses the sleeve 92 tightly, the upward pushing component 1201 pushes the mounting post 91 upward until the upper end of the mounting post 91 abuts against the top wall of the positioning notch 1209, and then it can be ensured that the actual protruding length of the upper end of the mounting post 91 protruding from the upper end of the sleeve 92 is equal to the standard protruding length L, thereby achieving the accurate positioning of the mounting post 91.

[0120] Preferably, the positioning pressure rod 1207 is detachably connected to the riveting female block 1204, so that different positioning pressure rods 1207 can be replaced as needed to adapt to different sizes of the sleeve 92, different sizes of the mounting post 91, and the length of the mounting post 91 extending above the sleeve 92. For example Figure 16 In Figure 16 , a vertically extending threaded hole is provided in the center of the riveting female block 1204, the positioning pressure rod 1207 is a screw rod adapted to the threaded hole, and the positioning pressure rod 1207 is threadedly connected to the threaded hole, but the detachable connection method is not limited to this.

[0121] Specifically, see Figure 15 , the upper pressing component 1201 includes a top rod 1210 capable of moving up and down and a third driving device 1211 for driving the top rod 1210 to move up and down.

[0122] Among them, the third driving device 1211 can be a cylinder, a hydraulic cylinder, an electric telescopic rod or a linear motor, etc., but is not limited to this.

[0123] Furthermore, a compression spring 1212 can be connected between the top rod 1210 and the third driving device 1211. For example Figure 15 In Figure 15 , the third driving device 1211 is a cylinder, and a compression spring 1212 is coaxially connected between the output shaft of the cylinder and the top rod 1210.

[0124] Through the compression spring 1212, it can be ensured that the mounting post 91 reliably abuts against the top wall of the positioning notch 1209, and the positioning accuracy requirement for the third driving device 1211 can be reduced.

[0125] Specifically, see Figures 13 - 16 , the end of the pressing block 1206 away from the positioning pressure rod 1207 extends radially out of the riveting female block 1204;

[0126] The riveting actuating component 1203 includes a first carriage 1213 capable of moving up and down, a fourth driving device 1214 for driving the first carriage 1213 to move up and down, and a plurality of pushing blocks 1215 provided at the lower end of the first carriage 1213. The number of the pushing blocks 1215 is equal to the number of the pressing blocks 1206, and each pushing block 1215 and each pressing block 1206 correspond to each other in the circumferential position. The end face of the pressing block 1206 away from the positioning pressure rod 1207 is a first guiding inclined surface A that gradually moves away from the positioning pressure rod 1207 from top to bottom. The pushing block 1215 has a second guiding inclined surface B that gradually moves away from the positioning pressure rod 1207 from top to bottom. When the pushing block 1215 moves down with the first carriage 1213, the first guiding inclined surface A is squeezed through the second guiding inclined surface B to make the corresponding pressing block 1206 move inwards.

[0127] During operation, when the positioning pressure rod 1207 presses against the sleeve 92 and the upper lifting assembly 1201 reaches the upper limit, the first carriage 1213 moves downward. Then, the pushing block 1215 pushes the pressing block 1206 inward to complete the riveting. The structure of the riveting actuating assembly 1203 is simple and reliable, and it can effectively achieve the synchronous movement of multiple pressing blocks 1206 to complete the riveting, ensuring the riveting quality.

[0128] Among them, the fourth driving device 1214 can be a cylinder, a hydraulic cylinder, an electric telescopic rod, a linear motor, etc., but is not limited thereto.

[0129] Among them, the inclination angles of the first guiding inclined surface A and the second guiding inclined surface B can be set according to the required stroke of the pressing block 1206.

[0130] Preferably, the pushing block 1215 and the first carriage 1213, as well as the pressing block 1206 and the riveting mother block 1204, are all connected in a detachable manner. Thus, the pressing block 1206 with a first guiding inclined surface A of different inclination angles and the pushing block 1215 with a corresponding inclination angle of the second guiding inclined surface B can be replaced according to actual needs to meet the different stroke requirements of the pressing block 1206 and improve the applicability.

[0131] Furthermore, as shown in Figure 14 , the end of the pressing block 1206 away from the positioning pressure rod 1207 is of a T-shaped structure. Two return springs 1216 are connected between each T-shaped structure and the riveting mother block 1204. The return springs 1216 are used to provide a return force for the pressing block 1206 away from the positioning pressure rod 1207.

[0132] Thus, when the first carriage 1213 moves upward, the pressing block 1206 will automatically move outward and reset under the action of the return force of the return spring 1216, avoiding hindering the entry of the next sleeve 92.

[0133] Preferably, as shown in Figure 1 , Figure 19 , the multiple assembly mechanisms 4 further include a cleaning mechanism 14 located between the blanking mechanism 13 and the first feeding mechanism 6. The cleaning mechanism 14 includes an air suction cylinder 1401 and a fifth driving device 1402 for driving the air suction cylinder 1401 to approach or move away from the positioning fixture 3. The air suction cylinder 1401 is connected to an external vacuum adsorption device and is used to suck air and clean the positioning fixture 3.

[0134] [[ID=:27]]When the positioning fixture: 3 completes blanking and moves to the cleaning mechanism 14, the fifth driving device 1402 drives the air suction cylinder 1401 to move towards the positioning fixture 3, and then sucks air through the air suction cylinder 1401 to suck metal debris or other sundries that may exist in the positioning groove 301, positioning hole 302, and detection through hole 303 of the positioning fixture 3, avoiding affecting the positioning accuracy of the positioning fixture 3 for the next static contact component.

[0135] Among them, the fifth driving device 1402 can be a cylinder, a hydraulic cylinder, an electric telescopic rod, a linear motor, etc., but is not limited thereto.

[0136] In this embodiment, as shown in Figure 3 , a turntable driving device 20 is provided in the machine table 1. The turntable driving device 20 is used to drive the circular turntable 2 to rotate step by step, so that the positioning fixture 3 can accurately align with each assembly mechanism 4 in sequence.

[0137] Specifically, the turntable driving device 20 includes a driving motor 2001, a gear reduction box 2002, a belt transmission mechanism 2003, and a rotation positioning sensor 2004. The output shaft of the driving motor 2001 is connected to the input shaft of the gear reduction box 2002 through the belt transmission mechanism 2003. The output shaft of the gear reduction box 2002 is connected to the circular turntable 2. The rotation positioning sensor 2004 is connected to the input shaft or the output shaft of the gear reduction box 2002 (for example Figure 3 in the figure, the rotation positioning sensor 2004 is connected to the input shaft of the gear reduction box 2002). Through the deceleration effect of the gear reduction box 2002 and the angle detection function of the rotation positioning sensor 2004, based on the positioning accuracy of the driving motor 2001 itself, the rotation angle positioning accuracy of the circular turntable 2 can be further improved.

[0138] Among them, the rotation positioning sensor 2004 can be a rotary encoder, a grating sensor, a capacitive positioning sensor, etc., but is not limited thereto.

[0139] For example Figure 3 in the figure, the rotation positioning sensor 2004 includes a connection disk 2005 key-connected to the input shaft of the gear reduction box 2002, a metal detection plate 2006 fixedly connected to the connection disk 2005, and a capacitive sensor 2007 arranged on one radial side of the connection disk 2005. The capacitive sensor 2007 has two capacitor plates. When the metal detection plate 2006 rotates with the connection disk 2005, it can pass between the two capacitor plates.

[0140] When the metal detection plate 2006 reaches between the two capacitor plates, it will reduce the voltage between the two capacitor plates of the capacitive sensor 2007, forming a trigger signal. The input shaft of the gear reduction box 2002 triggers the capacitive sensor 2007 once every rotation. Thus, the main control device 5 can calculate the rotation angle of the circular turntable 2 according to the pulse number of the trigger signal of the capacitive sensor 2007 and the transmission ratio of the gear reduction box 2002, so as to accurately control the rotation angle of the circular turntable 2.

[0141] Specifically, as shown in Figure 6The first feeding mechanism 6 includes a first spiral vibration disk 601, a first arrangement channel 602, a first feeding two-finger clamp 603 and a first feeding drive mechanism 604; the first spiral vibration disk 601 is used to input the installation columns 91 one by one into the first arrangement channel 602, and the first arrangement channel 602 is used to arrange the installation columns 91 entering therein into a row so as to be transmitted in sequence toward one side of the circular turntable 2, wherein the first arrangement channel 602 has an inverted T-shaped cavity adapted to the installation column 91, and the installation column 91 is transmitted in the inverted T-shaped cavity with the column cap 94 facing downward, so that the first feeding two-finger clamp 603 can grab the installation column 91; the first feeding drive mechanism 604 is used to drive the first feeding two-finger clamp 603 to the output end of the first arrangement channel 602 to grab the front end (that is, the closest to the output end) of the installation column 91 and insert it into the positioning hole 302 of the positioning fixture 3.

[0142] The first feeding drive mechanism 604 may be a robotic arm or a two-axis drive device, but is not limited thereto. Figure 6 In the figure, the first feeding drive mechanism 604 is a two-axis drive device, which can drive the first feeding two-finger clamp 603 to move back and forth and up and down along the radial direction of the circular turntable 2; the two-axis drive device can be a cylinder-driven two-axis drive device or a screw-driven two-axis drive device, but is not limited to this.

[0143] Specifically, see Figure 8 The second feeding mechanism 8 includes a second spiral vibrating disk 801, a second arrangement channel 802, a first transfer mechanism 803, a first stopping mechanism 804, a feeding suction cup 805 and a second feeding driving mechanism 806. The second spiral vibrating disk 801 is used to input the fixed contact pieces 90 one by one into the second arrangement channel 802. The second arrangement channel 802 is used to arrange the fixed contact pieces 90 entering therein into a row so as to be sequentially transferred toward the side of the circular turntable 2; the first transfer mechanism 803 is movably arranged at the output end of the second arrangement channel 802, and is used to receive a fixed contact piece 90 output from the second arrangement channel 802 and transfer the fixed contact piece 90 to the material taking station (the material taking station is located at the output end of the second arrangement channel 802). The first stop mechanism 804 is used to lock the fixed contact piece 90 at the front end (i.e., closest to the output end) in the second arrangement channel 802 after a fixed contact piece 90 is sent into the first transfer mechanism 803 in the second arrangement channel 802 (thereby stopping the transmission of all fixed contact pieces 90 in the second arrangement channel 802) until the fixed contact piece 90 in the first transfer mechanism 803 is taken out and the first transfer mechanism 803 is reset to release the lock; the second loading drive mechanism 806 is used to drive the loading suction cup 805 to take out the fixed contact piece 90 in the first transfer mechanism 803 at the material picking station and put it into the positioning groove 301 of the positioning fixture 3.

[0144] Among them, the second loading driving mechanism 806 can be a robotic arm or a two-axis driving device, but is not limited thereto. For example Figure 8 In Figure 8 , the second loading driving mechanism 806 is a two-axis driving device, which can drive the loading suction cup 805 to reciprocate radially and vertically along the circular turntable 2; the two-axis driving device can be a two-axis driving device driven by a cylinder or a two-axis driving device driven by a screw rod, but is not limited thereto.

[0145] Among them, the first transfer mechanism 803 includes a transfer seat 807 that can approach or move away from the output end of the second arrangement channel 802 and a transfer driving device 808 that drives the transfer seat 807 to reciprocate. A receiving groove 812 adapted to the fixed contact 90 is provided on the top of the transfer seat 807; the second arrangement channel 802 can send the frontmost fixed contact 90 into the receiving groove 812.

[0146] During operation, when the second arrangement channel 802 sends the frontmost fixed contact 90 into the receiving groove 812, the first stopping mechanism 804 locks the fixed contact 90 at the frontmost position in the second arrangement channel 802 at this time. Then, the transfer driving device 808 drives the transfer seat 807 to move to the material taking station. After the loading suction cup 805 takes out the fixed contact 90 on the transfer seat 807, the transfer driving device 808 drives the transfer seat 807 to reset. Then, the first stopping mechanism 804 releases the lock, and the next fixed contact 90 is sent into the receiving groove 812 again, and so on in a cycle.

[0147] Among them, the first stopping mechanism 804 includes a guiding cover plate 809 covering the upper side of the outlet of the second arrangement channel 802, a locking column 810 vertically arranged above the guiding cover plate 809 and capable of moving up and down, and a locking column driving device 811 that drives the locking column 810 to move up and down. An insertion through hole C adapted to the locking column 810 is provided on the guiding cover plate 809. The locking column 810 aligns with the insertion through hole C and can pass through the insertion through hole C to press and lock the frontmost fixed contact 90 in the second arrangement channel 802.

[0148] Preferably, the guiding cover plate 809 extends beyond the second arrangement channel 802 along the transmission direction of the fixed contact 90 in the second arrangement channel 802. When the first transfer mechanism 803 resets (at this time, the receiving groove 812 is aligned with the output end of the second arrangement channel 802), the guiding cover plate 809 is partially located above the receiving groove 812, so as to guide the fixed contact 90 during the process of the fixed contact 90 moving from the second arrangement channel 802 to the receiving groove 812, ensure that the fixed contact 90 accurately falls into the receiving groove 812, and realize accurate positioning of the fixed contact 90 in the receiving groove 812.

[0149] Among them, the locking column driving device 811 can be a cylinder, a hydraulic cylinder, an electric telescopic rod or a linear motor, etc., but is not limited thereto.

[0150] Specifically, see Figure 10 、 Figure 11 The third feeding mechanism 10 includes a third spiral vibration disk 1001, a third arrangement channel 1002, a second stopping mechanism 1003, a second feeding two-finger clamp 1004 and a third feeding drive mechanism 1005. The third spiral vibration disk 1001 is used to input the sleeves 92 one by one into the third arrangement channel 1002. The third arrangement channel 1002 is used to arrange the sleeves 92 entering therein in a row so as to be transmitted toward one side of the circular turntable 2 in sequence; the third feeding drive mechanism 1005 is used to drive the second feeding two-finger clamp 1004 from the third arrangement channel The front end sleeve 92 is taken out from the output end of the channel 1002 and placed in the positioning fixture 3 (inserted into the mounting column 91 in the positioning fixture 3); the second stopping mechanism 1003 is used to lock the sleeve 92 located at the front end of the third arrangement channel 1002 after the second loading two-finger clamp 1004 takes out the sleeve 92 (thereby stopping the transmission of all sleeves 92 in the third arrangement channel 1002), until the second loading two-finger clamp 1004 moves to the output end of the third arrangement channel 1002 again to clamp the sleeve 92 and contact lock it.

[0151] The third feeding drive mechanism 1005 may be a robotic arm or a two-axis drive device, but is not limited thereto. Figure 10 In the figure, the third feeding drive mechanism 1005 includes a rotating shaft 1006, a rotating motor 1007 for driving the rotating shaft 1006 to rotate back and forth, and a two-axis driving device for driving the rotating shaft 1006 and the rotating motor 1007 to move (the two-axis driving device can be a two-axis driving device driven by a cylinder or a two-axis driving device driven by a screw, but not limited to this). The second feeding two-finger clamp 1004 is fixedly connected to the rotating shaft 1006, and the rotating shaft 1006 is used to drive the second feeding two-finger clamp 1004 to swing up and down; the sleeve 92 is transmitted horizontally along the axial direction in the third arrangement channel 1002. When the second feeding two-finger clamp 1004 clamps the sleeve 92 from the output end of the third arrangement channel 1002, it first swings to a horizontal state, and then swings to a vertical downward state after clamping the sleeve 92, so as to facilitate the sleeve 92 to be inserted into the mounting column 91.

[0152] Among them, see Figure 11, the second stopping mechanism 1003 includes an upper cover plate 1008 covering the upper side of the output end of the third arranging channel 1002, an extending convex block 1009 protruding from the lower side of the output end of the third arranging channel 1002 along the transmission direction of the sleeve 92 in the third arranging channel 1002, a stopping column 1010 capable of moving up and down to extend out of the upper surface of the extending convex block 1009 or retract into the extending convex block 1009, and a stopping column driving device 1011 for driving the stopping column 1010 to move up and down; the upper surface of the extending convex block 1009 is an arc-shaped surface adapted to the circumferential surface of the sleeve 92, and a vertically extending sliding hole is opened at one end of the upper surface of the extending convex block 1009 away from the third arranging channel 1002, the stopping column 1010 slides through the sliding hole, and the diameter of the stopping column 1010 and the width of the extending convex block 1009 are both smaller than the diameter (referring to the outer diameter) of the sleeve 92.

[0153] During operation, the stopping column 1010 extends out of the upper surface of the extending convex block 1009, thereby blocking the sleeve 92 entering the extending convex block 1009, achieving the positioning of the sleeve 92 (and stopping the conveyance of all the sleeves 92 in the third arranging channel 1002). When the second feeding two-finger gripper 1004 horizontally clamps the sleeve 92 entering the extending convex block 1009, the stopping column 1010 retracts into the extending convex block 1009 (since the width of the extending convex block 1009 is smaller than the diameter of the sleeve 92, the second feeding two-finger gripper 1004 can clamp the sleeve 92; and since the diameter of the stopping column 1010 is smaller than the diameter of the sleeve, the second feeding two-finger gripper 1004 clamping the sleeve 92 does not affect the expansion and contraction of the stopping column 1010), thereby the second feeding two-finger gripper 1004 extracts the sleeve 92 on the extending convex block 1009. Before the next sleeve 92 moves to the position where the stopping column 1010 is located, the stopping column 1010 extends out of the upper surface of the extending convex block 1009 again, so that the next sleeve 92 is blocked by the stopping column 1010 after entering the extending convex block 1009, and so on in a cycle.

[0154] Among them, the lower surface of the upper cover plate 1008 is an arc-shaped surface adapted to the circumferential surface of the sleeve 92, and the upper cover plate 1008 partially extends above the extending convex block 1009, and the width of the part of the upper cover plate 1008 extending above the extending convex block 1009 is smaller than the diameter of the sleeve (referring to the outer diameter); thus, the upper cover plate 1008 can cooperate with the extending convex block 1009 to clamp the sleeve 92 entering the extending convex block 1009 from above and below, preventing the sleeve 92 from falling laterally (i.e., in the direction perpendicular to the axial direction).

[0155] Among them, the stopping column driving device 1011 can be selected from a cylinder, a hydraulic cylinder, an electric telescopic rod or a linear motor, etc., but is not limited thereto.
