[0031] Referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 8 and Figure 10 , Figure 1 is the axonometric drawing of the relay housing assembly device of the first embodiment, Figure 2 is Figure 1Axonometric view of the middle housing device 100 Figure 4 is Figure 1 Axonometric view of the middle housing positioning device 200 Figure 8 is Figure 1 Axonometric view of the middle lifting device 300 Figure 10 is Figure 1 Axonometric view of the middle clamping device 400. The relay housing assembly device of this embodiment includes a housing device 100, a housing positioning device 200, a lifting device 300, a clamping device 400 and a frame 500.

The housing device 100 is arranged on the first fixed seat 510, while the housing positioning device 200, the lifting device 300 and the clamping device 400 are all arranged on the second fixed seat 520. The housing device 100 is used to carry and set the housing. When the housing is assembled with the relay without the housing installed, the housing positioning device 200 can play a role in positioning the housing. The clamping device 400 is arranged at the output end of the lifting device 300. The clamping device 400 is used to clamp and position the relay without the housing installed. The lifting device 300 can move the clamping device 400 along the Y-axis direction, so as to facilitate the clamping device 400 to pick up the relay without the housing installed.

[0032] Refer to Figure 1 , Figure 2 and Figure 3 . Figure 3 is Figure 2 Exploded view. The housing device 100 includes a third driving device, a mounting frame 130 and a material taking head 140. Among them, the third driving device includes a first motion module 110 and a second motion module 120. The first motion module 110 is arranged on the first fixed seat 510. The second motion module 120 is arranged at the output end of the first motion module 110. The mounting frame 130 is fixed at the output end of the second motion module 120. The material taking head 140 is fixed on the mounting frame 130. Driven by the first motion module 110, the second motion module 120 can move along the Z-axis direction, that is, the material taking head 140 can move along the Z-axis direction, so that the material taking head 140 can reciprocate between the feeding place and the installation place to realize continuous feeding of the housing; driven by the second motion module 120, the material taking head 140 can move along the Y-axis direction, so as to set the housing on the relay without the housing installed.

[0033] In this embodiment, the first motion module 110 includes a first cylinder 111 and a first sliding pair 112. The cylinder block of the first cylinder 111 is locked and fixed on the first fixed seat 510. The first sliding pair 112 includes a first slide rail 113 and a first slider 114. The first slide rail 113 is locked and fixed on the first fixed seat 510. The first slider 114 is slidably connected to the first slide rail 113, and the first slider 114 is locked and fixed on the push rod of the first cylinder 111. Thus, under the action of the first cylinder 111, the first slider 114 can reciprocate in the Z-axis direction. Similar to the structure of the first motion module 110, the second motion module 120 includes a second cylinder 121 and a second sliding pair 122. The cylinder block of the second cylinder 121 is locked and fixed on the first slider 114. The second sliding pair 122 includes a second slide rail and a second slider. The second slide rail is locked and fixed on the first slider 114. The second slider is slidably connected to the second slide rail, and the second slider is locked and fixed on the push rod of the second cylinder 121. Under the action of the second cylinder 121, the second slider can reciprocate in the Y-axis direction, and the mounting bracket 130 is locked and fixed on the second slider.

[0034] In another embodiment, both the first motion module 110 and the second motion module 120 can be replaced by a combined device of a motor, a lead screw, and a nut.

[0035] In this embodiment, the material taking head 140 is a vacuum suction nozzle, and the vacuum suction nozzle is communicated with a vacuum air source to adsorb the outer shell on the vacuum suction nozzle.

[0036] In another embodiment, the material taking head 140 also uses a clamping jaw cylinder.

[0037] Referring to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , Figure 5 is Figure 4 an exploded view of Figure 6 is Figure 4 a top view of the positioning block 220 in Figure 7 is Figure 6 a cross-sectional view along the A-A section in Figure 8) The first vertical plate 521 and the second vertical plate 523 are arranged in parallel, and one end of the first vertical plate 521 and one end of the second vertical plate 523 are both locked and fixed to the bottom plate 522 by screws. The cylinder block of the third cylinder is locked and fixed to the side surface of the first vertical plate 521 away from the second vertical plate 523. The first fixing plate 230 is fixed to the push rod of the third cylinder. The positioning block 220 is locked and fixed to one end of the first fixing plate 230 in the positive Y-axis direction.

[0038] Among them, to improve the load-bearing capacity of the first fixing plate 230 and at the same time limit the movement direction of the first fixing plate 230, a third sliding pair 240 is provided. The third sliding pair 240 includes a third slide rail and a third slider. The third slide rail is locked and fixed to the first vertical plate 521. The third slider is slidably connected to the third slide rail, and the third slider is locked and fixed to the first fixing plate 230. Thus, the first fixing plate 230 is slidably connected to the second fixing seat 520, and the first fixing plate 230 can move relative to the second fixing seat 520 along the Y-axis direction.

[0039] A positioning hole 221 is provided at one end of the positioning block 220 away from the first fixing plate 230. The positioning hole 221 is in clearance fit with the housing. Thus, the housing can enter the positioning hole 221. At the same time, the positioning hole 221 can limit the housing. Under the action of the third cylinder, the positioning block 220 can move along the Y-axis direction (the Y-axis direction is the first direction). A tapered opening is also provided at one end of the positioning hole 221 in the positive Y-axis direction. The tapered opening is beneficial for the housing to enter the positioning hole 221.

[0040] In another embodiment, similar to the first motion module 110 and the second motion module 120, the second driving device 210 can also be replaced by a combination device of a motor, a lead screw, and a nut.

[0041] Refer to Figure 1 、 Figure 8 and Figure 9 , Figure 9 is Figure 8 an exploded view of. The lifting device 300 includes a fourth driving device 310, a fourth sliding pair 320, and a second fixing plate 330. In this embodiment, the fourth driving device 310 is a fourth cylinder, and there are two pairs of the fourth sliding pair 320 and the second fixing plate 330. One second fixing plate 330 is slidably connected to the first vertical plate 521 through the fourth sliding pair 320, and the other second fixing plate 330 is slidably connected to the second vertical plate 523 through the fourth sliding pair 320. And both second fixing plates 330 are located between the first vertical plate 521 and the second vertical plate 523. Both ends of the mounting plate 490 are locked and fixed to the two second fixing plates 330. The cylinder block of the fourth cylinder is locked and fixed to the second vertical plate 523. The push rod of the fourth cylinder is fixedly connected to the mounting plate 490. Under the drive of the fourth cylinder, the mounting plate 490 can move along the Y-axis direction.

[0042] Refer to Figure 1 、 Figure 10 、 Figure 11 and Figure 12 , Figure 11 is Figure 10 an exploded view of Figure 12 is Figure 1 an axonometric view of the first clamping block in

[0043] The mounting plate 490 is provided with a first chute 491, a second chute 492 and a third chute 493. The third chute 493 is arranged along the X-axis direction, and the first chute 491 and the second chute 492 are both arranged along the Z-axis direction, and the first chute 491 and the second chute 492 are respectively located on both sides of the third chute 493. The first clamping block 470 is placed in the first chute 491, and the second clamping block 480 is placed in the second chute 492. Thus, both the first clamping block 470 and the second clamping block 480 can move relative to the mounting plate 490 along the Z-axis direction, and one end of the first clamping block 470 and one end of the second clamping block 480 are aligned. The third clamping block 450 is placed in the third chute 493. Thus, the third clamping block 450 can move relative to the mounting plate 490 along the X-axis direction.

[0044] The first end of the first ejector rod 430 (the end of the first ejector rod 430 in the positive Y-axis direction is its first end) is provided with a first inclined surface 431 and a second inclined surface 432. After the first ejector rod 430 passes through the mounting plate 490 in the positive Y-axis direction (the mounting plate 490 is provided with a through hole along the Y-axis direction), the first inclined surface 431 abuts against the first clamping block 470, and the second inclined surface 432 abuts against the second clamping block 480. Thus, when the first ejector rod 430 moves in the positive Y-axis direction, under the action of the first inclined surface 431, the first clamping block 470 will move in the positive Z-axis direction. At the same time, under the action of the second inclined surface 432, the second clamping block 480 will move in the negative Z-axis direction, that is, the first clamping block 470 and the second clamping block 480 will move away from each other.

[0045] To reduce the sliding friction between the first inclined surface 431 and one end of the first clamping block 470, an arc surface 473 is provided at one end of the first clamping block 470 in the negative Z-axis direction. The insertion of the arc surface 473 and the first inclined surface 431 is a line insertion, and compared with point contact, the friction force is smaller. The second clamping block 480 is the same in this regard.

[0046] To enable the first ejector rod 430 to move in the negative Y-axis direction, the first clamping block 470 and the second clamping block 480 can approach each other. A first elastic element is provided, and the first elastic element gives the first clamping block 470 an elastic force to move in the negative Z-axis direction. In this embodiment, the first elastic element is a first compression spring. One end of the first compression spring abuts against the mounting plate 490, and the other end of the first compression spring abuts against the first clamping block 470. In the initial state, the first compression spring is in a compressed state. Thus, under the action of the first compression spring, the first clamping block 470 can move in the negative Z-axis direction. Similarly, the second clamping block 480 also realizes its movement in the positive Z-axis direction by setting a second elastic element.

[0047] In another embodiment, the first elastic element can also be selected as a corrugated tube. The setting of the corrugated tube is the same as that of the first compression spring, and the second elastic element is also selected as a second compression spring or a compression spring.

[0048] A first abutting surface 471 and a third abutting surface 472 are provided on the first clamping block 470 (refer to Figure 12 ), correspondingly, a second abutting surface 481 is provided on the second clamping block 480. The second abutting surface 481 is disposed opposite to the first abutting surface 471 (i.e., face to face). When the first clamping block 470 and the second clamping block 480 approach each other, the relay without an installed housing can be clamped through the first abutting surface 471 and the second abutting surface 481.

[0049] To realize the positioning of the relay without an installed housing, a third clamping block 450 and a second ejector rod 440 are further provided. The principle that the second ejector rod 440 drives the third clamping block 450 to move in the positive X-axis direction is the same as the principle that the first ejector rod 430 drives the first clamping block 470 to move in the positive Z-axis direction. A third inclined surface 441 is provided on the second ejector rod 440. After the second ejector rod 440 passes through the mounting plate 490 at one end in the positive Y-axis direction, the third inclined surface 441 abuts against the shaft 610 fixed on the third clamping block 450 (the shaft 610 is inserted into the waist-shaped hole on the mounting plate 490). Under the action of the third inclined surface 441, the third clamping block 450 moves in the positive X-axis direction.

[0050] To enable the third clamping block 450 to move in the negative X-axis direction, a third elastic element 460 is provided. The third elastic element 460 gives the third clamping block 450 an elastic force to move in the negative X-axis direction. The third elastic element 460 is similar to the first elastic element and can also be selected as the second compression spring or the compression spring.

[0051] A fourth abutting surface 451 is provided on the third clamping block 450. The fourth abutting surface 451 is disposed opposite to the third abutting surface 472. Since the second ejector rod 440 is locked and fixed to the first ejector rod 430, under the action of the fifth cylinder, the second ejector rod 440 and the first ejector rod 430 move synchronously. Thus, the four sides of the relay without the installed housing are respectively abutted against the first abutting surface 471, the second abutting surface 481, the third abutting surface 472, and the fourth abutting surface 451, thereby realizing the positioning of the relay without the installed housing.

[0052] In summary, the working process of the relay housing assembly device of this embodiment is as follows. Driven by the lifting device 300, the clamping device 400 moves in the positive Y-axis direction. The first clamping block 470, the second clamping block 480, and the third clamping block 450 respectively move to the periphery of the relay without the installed housing. The first ejector rod 430 and the second ejector rod 440 move in the negative Y-axis direction under the action of the fifth cylinder. The first clamping block 470 and the second clamping block 480 approach each other under the action of the elastic force. At the same time, the third clamping block 450 also approaches the relay without the installed housing under the action of the elastic force. Finally, the first clamping block 470, the second clamping block 480, and the third clamping block 450 clamp and position the relay without the installed housing. At this time, the positioning block 220 moves in the negative Y-axis direction under the action of the third cylinder, so as to approach the relay without the installed housing. After the housing sleeve device 100 obtains the housing through the vacuum suction nozzle, it moves in the positive Z-axis direction, so that the housing is aligned with the positioning hole 221. Under the action of the second cylinder, the vacuum suction nozzle drives the housing to move in the negative Y-axis direction, and the housing is installed on the relay without the installed housing through the positioning hole 221, thereby realizing the installation of the housing.

[0053] In this embodiment, to improve the working efficiency, four groups are provided for the first clamping block 470, the second clamping block 480, the third clamping block 450, the positioning block 220, and the material taking head 140. The four groups of material taking heads can obtain four housings at one time and complete the assembly of four relays.

[0054] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
