[0041] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the embodiments of the present invention and should not be construed as a limitation of the present invention.

[0042] As Figures 1 to 23 , the embodiment of the present invention provides a linear caliper assembly device, including a frame 100 and a elastic piece mounting assembly 200, a screw locking assembly 300 and a conveyor assembly 400 mounted on the frame 100. The conveyor assembly 400 is used to drive the calipers 50 to be assembled to move and intermittently stay at positions corresponding to the elastic piece mounting assembly 200 and the screw locking assembly 300. The elastic piece mounting assembly 200 includes a clamping member 210 and a top pushing member 220 that can slide relative to the frame 100 in the vertical direction. The clamping member 210 can clamp the arc-shaped elastic piece 530. The clamping member 210 can press on the middle part of the elastic piece 530 to hold the elastic piece 530 on the ruler body of the calipers 500 to be assembled. The top pushing member 220 can press down the tail end of the elastic piece 530 and move towards the ruler head of the calipers 500 to insert the elastic piece 530 into the ruler head 520 of the calipers 500; The screw locking assembly 300 includes a guide post 310 and a push rod 320. The guide post 310 is arranged on the frame 100. The guide post 310 is provided with a central hole 314 extending in the vertical direction. The push rod 320 slides vertically through the central hole 314. The push rod 320 can rotate around its own axis. The push rod 320 is configured to be able to push the screw 540 in the central hole 314 out of the central hole 314 and screw it into the screw mounting hole position 550 on the calipers 520.

[0043] It can be understood that during installation, the conveying component 400 can drive the caliper 500 to be assembled to first move to the elastic piece installation component 200. The clamping piece 210 clamps the arc-shaped elastic piece 530, transfers the elastic piece 530 to the caliper 500 and presses it down on the caliper 500. Then, the pushing piece 220 can press down the tail end of the elastic piece 530. Through the movement of the pushing piece 220, the elastic piece 530 can be inserted into the head 520 of the caliper 500, realizing the automatic assembly of the elastic piece 530. Then, the conveying component 400 can drive the caliper 500 installed with the elastic piece 530 to move to a position corresponding to the screw locking component 300. The push rod 320 on the frame 100 can move and rotate relative to the guide post 310 along the central hole 314, so as to screw the screw 540 in the central hole 314 into the screw installation hole position 550 on the head 520, realizing the automatic assembly of the screw 540. In summary, the present invention can realize the automatic assembly of the elastic piece 530 and the screw 540, save labor costs and improve the assembly efficiency.

[0044] It should be noted that the conveying component 400 can be a chain or a conveyor belt. A number of jigs can be placed on the conveying component 400. The jigs are used to temporarily fix and support the caliper 500. Specifically, the caliper 500 to be assembled can be loaded onto the conveying component 400 by common equipment in the field such as a manipulator or a feeding gripper, and the conveying component 400 drives the caliper 500 to be assembled to move towards the elastic piece installation component 200 and the screw locking component 300. The assembled caliper 500 can be unloaded by another manipulator or a discharging gripper. In addition, it should be noted that in the present application, the screw locking component 300 can be set in one group or multiple groups as needed. For example Figure 1 As shown, three groups of screw locking components 300 are provided in the embodiment of the present invention for locking screws at three different positions on the caliper 500.

[0045] Such as Figure 4 As shown, in one embodiment of the present invention, the guide post 310 is composed of a cylindrical body 311, a clamping block 312 and an elastic rubber sleeve 313. An installation groove 3111 is opened at the bottom of the cylindrical body 311. The clamping block 312 is located at the installation groove 3111 and jointly forms the central hole 314 with the cylindrical body 311. The rubber sleeve 313 is sleeved outside the cylindrical body 311 and simultaneously wraps the cylindrical body 311 and the clamping block 312. By setting the rubber sleeve 313 structure, the present invention can realize the elastic clamping of the screw 540, and while ensuring the clamping stability, it can also adapt to the outer diameter error of the screw 540 within a certain range.

[0046] Such as Figures 4 to 7As shown, in one embodiment of the present invention, a first groove 3112 is formed on the cylindrical body 311, and a second groove 3121 is formed on the clamping block 312. The first groove 3112 and the second groove 3121 together form an annular groove 315. At the position corresponding to the annular groove 315 on the inner circle of the rubber sleeve 313, an annular protrusion 3131 that can cooperate with the annular groove 315 is provided. The annular protrusion 3131 can cooperate with the annular groove 315 to fix the position of the rubber sleeve 313 relative to the cylindrical body 311 and the position of the clamping block 312 relative to the rubber sleeve 313, so that the center hole 314 can be stably maintained among the cylindrical body 311, the clamping block 312, and the rubber sleeve 313.

[0047] As Figure 6 and Figure 7 shown, in one embodiment of the present invention, the clamping block 312 is provided with a protruding portion 3122 along its own radial direction, and the cylindrical body 311 is provided with a recessed portion 3113 along its own radial direction. The protruding portion 3122 can cooperate with the recessed portion 3113 to limit the position of the clamping block 312 relative to the cylindrical body 311 in the vertical direction. When the clamping block 312 is fine-tuned in the horizontal direction relative to the cylindrical body 311, the cooperation between the protruding portion 3122 and the recessed portion 3113 can provide guidance for the horizontal movement of the clamping block 312 and limit the movement of the clamping block 312 in the vertical direction.

[0048] As Figures 4 to 6 shown, in one embodiment of the present invention, the outer diameter of the cylindrical body 311 gradually decreases near the installation groove 3111 and forms a tapered inclined surface 3114. The rubber sleeve 313 is provided with a guiding inclined surface 3132 that fits with the tapered inclined surface 3114 at the position corresponding to the tapered inclined surface 3114. The cooperation between the guiding inclined surface 3132 and the tapered inclined surface 3114 can facilitate the installation of the rubber sleeve 313. The rubber sleeve 313 can be made of deformable materials such as silicone. It is often difficult to avoid some errors in the processing dimensions of such deformable materials. By setting the inclined stepped surface, the assembly influence caused by the error in the length of the rubber sleeve 313 can be reduced.

[0049] As Figure 3 shown, in one embodiment of the present invention, the locking assembly 300 further includes a sliding seat 330, and the sliding seat 330 is configured to reciprocate relative to the frame 100 between the screw feeding station 110 and the screw installation station 120. As Figure 3As shown, the locking assembly 300 can slide in the front-rear direction and reciprocate to transfer the screw 540 between the screw loading station 110 and the screw installation station 120. In addition, the guide posts 310 and the push rod 320 are both arranged on the sliding seat 330. The feeding device 340 is docked with the screw vibrating disk 350. The feeding device 340 is used to receive the screws 540 output by the screw vibrating disk 350 and sequentially transfer the screws 540 to the screw loading station 110 of the frame 100. The screw vibrating disk 350 can arrange and output a number of scattered screws 540 in the same orientation. Such a screw vibrating disk 350 is a conventional device in the art, and its structure and principle will not be described in detail here. As Figure 8 and Figure 10 shown, the feeding device 340 includes a pushing cylinder 345. The pushing cylinder 345 is installed at the screw loading station 110 on the frame 100. The pushing cylinder 345 is configured to push the screw 540 located at the screw loading station 110 upward into the central hole 314 of the push rod 320. Specifically, a number of screws 540 can be sequentially transferred to the screw loading station 110. The frame 100 can also be provided with a detection grating at the screw loading station 110 to detect whether a screw 540 has been moved in place at the screw loading station 110.

[0050] As Figure 8 and Figure 9 shown, in one embodiment of the present invention, the feeding device 340 further includes a push plate 341. The push plate 341 is slidably arranged on the frame 100 in the horizontal direction. Specifically, as Figure 8 shown, the push plate 341 can slide in the left-right direction. The frame 100 also has a first receiving position 130 and a second receiving position 140. The push plate 341 is configured to reciprocate between the first receiving position 130 and the second receiving position 140. When the push plate 341 is located at the first receiving position 130, the push plate 341 can receive the screws 540 output by the screw vibrating disk 350. The push plate 341 can synchronously move the screws 540 to the second receiving position 140 when moving to the second receiving position 140, and then transfer the screws 540 at the second receiving position 140 to the screw loading station 110 through other transfer mechanisms. By setting the structure of the push plate 341, a number of screws 540 arranged and output by the screw vibrating disk 350 can be separated and sequentially moved to the second receiving position 140, which is convenient for transferring individual screws 540 in subsequent processes.

[0051] As Figure 9 shown, in one embodiment of the present invention, the push plate 341 has a material transfer groove 342. The material transfer groove 342 is used to receive the screws 540 output by the screw vibrating disk 350. The width and length of the material transfer groove 342 are both equal to the outer diameter of the screw 540, so that only one screw 540 can be accommodated in the material transfer groove 342 each time, which can effectively prevent interference or jamming during the feeding process of the screw 540.

[0052] As Figure 8 shown, in one embodiment of the present invention, the feeding device 340 further includes a turning block 343 that is reversely arranged on the frame 100. The turning block 343 is configured to be able to turn between the second receiving position 140 and the screw feeding station 110. Specifically, the turning block 343 can be driven by a motor to achieve turning. A material transfer hole 344 is provided on the turning block 343. As Figure 10 shown, another pushing cylinder 345 is provided in the area of the frame 100 corresponding to the second receiving position 140. The pushing cylinder 345 is configured to be able to push the screw 540 located at the second receiving position 140 upward into the material transfer hole 344. At this time, the top end of the screw 540 located in the material transfer hole 344 faces downward. After the turning block 343 turns, the screw 540 in the material transfer hole 344 is in a state where the top end faces upward. The pushing cylinder 345 located at the screw feeding station 110 is configured to be able to push the screw 540 located at the screw feeding station 110 upward into the central hole 314.

[0053] As Figures 11 to 23 shown, in one embodiment of the present invention, the frame 100 has a shrapnel feeding position 160 and a caliper mounting position 150. The shrapnel feeding device 250 is used to sequentially convey the bent shrapnel 530 from front to back to the shrapnel feeding position 160. The shrapnel mounting assembly 200 is arranged on the frame 100 and can reciprocate between the shrapnel feeding position 160 and the caliper mounting position 150. The shrapnel mounting assembly 200 has a first state where both the clamping member 210 and the pushing member 220 are on top, a second state where the clamping member 210 is below and the pushing member 220 is on top, a third state where both the clamping member 210 and the pushing member 220 are below, and a fourth state where the clamping member 210 is on top and the pushing member 220 is below. The shrapnel mounting assembly 200 is configured to be able to move to the shrapnel feeding position 160 in the first state and switch to the second state at the shrapnel feeding position 160 so that the clamping member 210 clamps the shrapnel 530; the shrapnel mounting assembly 200 can move back from the shrapnel feeding position 160 to the caliper mounting position 150 after switching back to the first state and switch to the third state at the caliper mounting position 150 to press the shrapnel 530 against the body 510 of the caliper 500. At this time, the clamping member 210 presses on the middle part of the shrapnel 530, and the pushing member 220 presses on the tail end of the shrapnel 530; the shrapnel mounting assembly 200 is configured to be able to move forward in the third state at the caliper mounting position 150 and push the head end of the shrapnel 530 into the head 520 of the caliper 500. When the shrapnel mounting assembly 200 located at the caliper mounting position 150 switches to the fourth state, the shrapnel mounting assembly 200 can move forward to completely push the shrapnel 530 into the head 520 of the caliper 500.

[0054] It can be understood that during installation, first, the shrapnel installation component 200 moves to the shrapnel loading position 160 in the first state; then the shrapnel installation component 200 switches to the second state and clamps the shrapnel 530 at the shrapnel loading position 160, and at this time the shrapnel 530 is in a bent state; then the shrapnel installation component 200 switches back to the first state and moves back to the Figure 14 shown caliper installation position 150; then the shrapnel installation component 200 Figure 15 switches to the third state as shown to press the shrapnel 530 against the body 510 of the caliper 500. At this time, the shrapnel 530 is in a straight state due to being pressed by the clamping member 210 and the pushing member 220. Then the shrapnel installation component 200 moves forward and Figure 16 pushes the leading end of the shrapnel 530 into the head 520 of the caliper 500 as shown; then the shrapnel installation component 200 switches to the fourth state. At this time, since the leading end of the shrapnel 530 is pressed against the head 520 of the caliper 500 and the trailing end is pressed against the pushing member 220, the shrapnel 530 can be kept in a straight state. Then the shrapnel installation component 200 continues to move forward to Figure 19 completely push the shrapnel 530 into the head 520 of the caliper 500 as shown. The device in the present invention can realize the automatic assembly of the bent shrapnel 530 and the caliper 500 by circulating the above steps, which can significantly improve the assembly efficiency and reduce the labor cost.

[0055] As Figures 14 to 19 shown, in one embodiment of the present invention, the pushing member 220 includes a base 221, a first top block 222, a second top block 223 and an elastic member 224. The first top block 222 and the second top block 223 are both horizontally slidably arranged in the base 221. The two ends of the elastic member 224 are respectively connected to the first top block 222 and the second top block 223. When the elastic member 224 is in the Figures 14 to 18 natural state as shown, the front end face of the first top block 222 is in front of the front end face of the second top block 223. At this time, there is a certain gap between the first top block 222 and the second top block 223 in the front-rear direction, and this gap can provide space for the sliding of the first top block 222 relative to the second top block 223; when the elastic member 224 is in the Figure 19 compressed state as shown, the front end face of the first top block 222 is behind the front end face of the second top block 223; the position of the rear end of the shrapnel 530 clamped by the clamping member 210 corresponds to the position of the front end face of the second top block 223 in the horizontal direction, so that the second top block 223 can Figure 11 be inserted into the head 520 of the caliper 500 as shown to completely insert the shrapnel 530 into the head 520 and prevent the trailing end of the shrapnel 530 from being exposed outside the head 520.

[0056] As Figures 14 to 19As shown, in one embodiment of the present invention, a driving cylinder 225 is provided on the base 221, and the driving cylinder 225 is configured to push and pull the second top block 223 back and forth in the front and rear directions to achieve the sliding of the second top block 223, and push the first top block 222 to slide through the second top block 223 and the elastic member 224, wherein the elastic member 224 can be a compression spring. It should be noted that Figure 14 and Figure 15 The driving cylinder 225 in the embodiment is in a contracted state. Figures 16 to 19 In addition, the displacement of the first top block 222 relative to the second top block 223 can be achieved by moving the spring sheet mounting assembly 200 as a whole in the front-to-back direction. Specifically, when the spring sheet mounting assembly 200 is in the Figure 18 When the spring sheet installation assembly 200 moves forward for a short distance, the front end surface of the first top block 222 is located in front of the front end surface of the second top block 223. At this time, the elastic member 224 is not compressed. When the spring sheet installation assembly 200 continues to move forward for a short distance, the spring sheet installation assembly is in Figure 19 At this time, the front end surface of the first top block 222 is as shown in FIG. Figure 20 As shown, it is located behind the front end surface of the second top block 223, and the elastic member 224 is in a compressed state at this time.

[0057] like Figure 21 As shown, in one embodiment of the present invention, the clamping member 210 includes a base 211 extending in the front-to-back direction and two clamping plates 212 located on the left and right sides of the base 211 and arranged parallel to each other, a tension spring (not shown in the figure) is arranged between the two clamping plates 212, the bottom surfaces of the two clamping plates 212 are located below the bottom surface of the base 211, and the spacing between the two clamping plates 212 is adapted to the width of the spring sheet 530. When the clamping member 210 clamps the spring sheet 530, the two clamping plates 212 are stretched apart and the spacing becomes larger, and the tension spring is in a stretched state at this time. The above structure of the clamping member 210 can be applied to clamping the bent spring sheet 530, that is, clamping the spring sheet 530 from the width direction of the spring sheet 530, so that the clamping transfer action can be achieved regardless of any changes in the bending degree of the spring sheet 530.

[0058] like Figure 22As shown, in one embodiment of the present invention, the shrapnel feeding device 250 includes a shrapnel vibrating disk 251 and a rotating block 252 both disposed on the frame 100. The shrapnel vibrating disk 251 is used to sequentially output shrapnel 530. The shrapnel 530 in the shrapnel vibrating disk 251 are all in a straight state. The shrapnel vibrating disk 251 can straighten a number of scattered strip-shaped shrapnel 530 and sequentially convey them to the output end of the shrapnel vibrating disk 251. The specific structure and principle of the shrapnel vibrating disk 251 for conveying strip-shaped parts are conventional technical means in the art and will not be elaborated here. The shrapnel 530 is conveyed backward along the inclined plane to the rotating block 252 at the output end of the shrapnel vibrating disk 251. By setting the inclined plane to convey the shrapnel 530, the shrapnel 530 can automatically slide downward along the inclined plane and be flush with the lower edge of the inclined plane, realizing the automatic alignment of a number of shrapnel 530 at the output end of the shrapnel vibrating disk 251. In addition, the rotating block 252 can rotate relative to the frame 100 around a rotation axis arranged in the front-back direction to flip the shrapnel 530 to a horizontal state, facilitating the subsequent clamping and transfer of the shrapnel 530 by the clamping jaw 256.

[0059] As Figure 23 shown, in one embodiment of the present invention, the shrapnel feeding device 250 further includes a trough 253, a clamping jaw 256 and a material pushing member 257.

The trough 253 has a first position 254, a second position 255 and a shrapnel feeding position 160. The clamping jaw 256 is configured to transfer the shrapnel 530 on the rotating block 252 to the first position 254 of the trough 253. The material pushing member 257 is configured to move relative to the frame 100 in the vertical, front-back and left-right directions to sequentially move the shrapnel 530 from the first position 254 to the second position 255 and the shrapnel feeding position 160. The frame 100 is provided with a first pressing block 230 at the second position 255. The first pressing block 230 is used to press down and bend the shrapnel 530 located at the second position 255 to press the straight shrapnel 530 into a bent shrapnel 530. The first pressing block 230 can be arranged above the trough 253 and move from top to bottom to achieve the pressing-down action. The frame 100 is provided with a second pressing block 240 at the shrapnel feeding position 160. The second pressing block 240 can be arranged below the trough 253. The second pressing block 240 is used to move upward and press the shrapnel 530 located at the shrapnel feeding position 160 into the space between two clamping plates 212 of the clamping member 210.

[0060] As Figure 23As shown, in one embodiment of the present invention, there are four material pushing members 257, which are arranged in two groups. The two material pushing members 257 in the same group can be respectively inserted into the positions in front of and behind the elastic sheet 530 in the groove body 253 and push the elastic sheet 530 backward, and the four material pushing members 257 can move synchronously. Specifically, the four material pushing members 257 can move upward synchronously, then move rightward synchronously, and then move downward synchronously to be inserted into the groove body 253. Then, the four material pushing members 257 can move backward synchronously to move the elastic sheet at the first position 254 to the second position 255, and move the elastic sheet 530 at the second position 255 to the elastic sheet loading position 160.

[0061] As Figure 23 shown, in one embodiment of the present invention, an avoidance block 260 is provided on the groove body 253. The avoidance block 260 and the groove body 253 are connected to each other by a compression spring. The clamping jaw 256 can downwardly press the avoidance block 260 when placing the elastic sheet 530, so that the clamping jaw 256 can smoothly place the elastic sheet 530 into the groove body 253. After the clamping jaw 256 leaves, the avoidance block 260 can be reset under the action of the compression spring. The reset avoidance block 260 can provide guidance for the forward and backward movement of the elastic sheet 530. Specifically, the avoidance block 260 can be set as a U-shaped structure. The two ends of the U-shaped structure can be downwardly pressed by the two ends of the clamping jaw 256, and the middle of the U-shaped structure can be used to support the elastic sheet 530 and provide guidance for the movement of the elastic sheet 530.

[0062] As Figure 22 shown, in one embodiment of the present invention, another avoidance block 260 is provided on the rotating block 252. The clamping jaw 256 can downwardly press the avoidance block 260 on the rotating block 252 when clamping the elastic sheet 530, so that the clamping jaw 256 can smoothly clamp the elastic sheet 530. After the clamping jaw 256 leaves, the avoidance block 260 can be reset under the action of the compression spring. The reset avoidance block 260 can provide guidance for the forward and backward movement of the elastic sheet 530. Specifically, the avoidance block 260 can be set as a U-shaped structure. The two ends of the U-shaped structure can be downwardly pressed by the two ends of the clamping jaw 256, and the middle of the U-shaped structure can be used to support the elastic sheet 530 and provide guidance for the movement of the elastic sheet 530.

[0063] As Figure 23 shown, in one embodiment of the present invention, the material pushing member 257 is in an L shape with the short side vertical.
