Description

Technical Field

[0001] This application relates to the field of automated processing technology, and in particular, to a variable pitch device. Background Art

[0002] During the process of part processing, it is necessary to screen the postures of the parts, perform appearance inspections, and then perform matrix sorting. Due to the requirements of adapting to the next processing procedure or processing equipment, the spacing positions of these parts need to be adjusted during matrix sorting.

[0003] Since different processing procedures or processing equipment have different requirements for the spacing of parts, in the prior art, parts are usually manually transferred to the matrix for pitch adjustment, and then transferred to the processing equipment for the next processing procedure. Since the spacing needs to rely on manual adjustment, the efficiency is low, thus affecting the overall efficiency of automated part processing. Utility Model Content

[0004] The purpose of this application is to provide a variable pitch device that can improve the efficiency of automated part processing.

[0005] A variable pitch device provided by this application adopts the following technical solutions:

[0006] A variable pitch device includes a frame, a conveying mechanism, a pushing mechanism, and a pitch adjusting mechanism. The conveying mechanism, the pushing mechanism, and the pitch adjusting mechanism are installed on the frame;

[0007] The conveying mechanism includes a conveyor belt and a driving assembly. The driving assembly is used to drive the conveyor belt to run. The pushing mechanism is installed at the end of the conveyor belt running direction, and the pitch adjusting mechanism is installed on one side of the pushing mechanism;

[0008] The conveying mechanism is used to convey a plurality of parts to the pushing mechanism. The pushing mechanism is used to push a plurality of parts to the pitch adjusting mechanism. The pitch adjusting mechanism is used to adjust the spacing of a plurality of parts.

[0009] By adopting the above technical solutions, this application conveys parts through the conveying mechanism, pushes the parts from the conveyor belt to the pitch adjusting mechanism through the pushing mechanism, and then adjusts the spacing of the parts through the pitch adjusting mechanism. The spacing adjustment between parts can be realized without manual operation throughout the process, effectively improving the efficiency of automated part processing.

[0010] Further, the pitch adjusting mechanism includes a first cylinder fixed on the side of the frame and a plurality of adjusting blocks connected to the output shaft of the first cylinder. The plurality of adjusting blocks are slidably connected to each other.

[0011] By adopting the above technical solution, the present application realizes the spacing adjustment through several adjusting blocks that are slidably connected to each other, ensuring the reliability of the part spacing adjustment.

[0012] Further, the adjusting block includes a sliding portion, a clamping portion, a connecting portion, and a placing portion. A clamping groove is formed on the side of the sliding portion away from the first cylinder;

[0013] The connecting portion is used to be inserted into the clamping groove of an adjacent adjusting block, and the clamping portion is used to be clamped with the clamping groove of the adjacent adjusting block so that two adjacent adjusting blocks are slidably connected to each other. The placing portion is used to place the parts pushed by the pushing mechanism to the spacing adjusting mechanism.

[0014] By adopting the above technical solution, the adjusting blocks of the present application are mutually clamped through the clamping portion and the clamping groove, so that two adjacent adjusting blocks are slidably connected to each other, thereby enabling the distance between parts to be adjusted by adjusting the distance between two adjacent adjusting blocks, realizing automatic part spacing adjustment.

[0015] Further, the width of the clamping groove is the same as the width of the clamping portion, and the length of the clamping groove is the same as the sum of the length of the clamping portion and the length of the connecting portion, so that when two adjacent adjusting blocks slide to make the sliding portions closely adhere to each other, the clamping groove completely accommodates the clamping portion and the connecting portion.

[0016] By adopting the above technical solution, the present application leaves a gap in the clamping groove to accommodate the connecting portion, so that the width of the connecting portion serves as the range within which the spacing between the adjusting blocks can be adjusted, ensuring that the range of part spacing adjustment can meet the requirements of different processing procedures or processing equipment.

[0017] Further, the spacing adjusting mechanism further includes a first slide rail and several first sliders. The first slide rail is installed on the side of the frame, and the several adjusting blocks are slidably connected to the first slide rail through the several first sliders, so that the several adjusting blocks slide along a direction parallel to the conveyor belt.

[0018] By adopting the above technical solution, the present application enables the adjusting blocks to slide along a direction parallel to the conveyor belt through the first slide rail and the first sliders, so that the distance between the adjusting blocks can be automatically adjusted, realizing automatic part spacing adjustment.

[0019] Further, the pushing mechanism includes a push plate, a second cylinder fixed at the end of the frame, a second slider connected to the output shaft of the second cylinder, and a second slide rail installed on the top of the second cylinder. The end of the push plate is slidably connected to the second slide rail through the second slider, so that the push plate slides along a direction perpendicular to the conveyor belt.

[0020] By adopting the above technical solution, in the present application, the push plate slides in a direction perpendicular to the conveyor belt to push the parts on the conveyor belt to the pitch adjustment mechanism, so as to realize the automation of the part transfer process and further improve the efficiency of part processing.

[0021] Furthermore, a limiting groove is formed at one end of the push plate away from the second slide rail. When the push plate is in the initial position, the limiting groove is aligned with the conveyor belt. When the push plate is in the pushed position, the limiting groove is aligned with the placement part of the adjustment block.

[0022] By adopting the above technical solution, in the present application, the limiting groove accommodates the parts conveyed by the conveyor belt to the pushing mechanism, and then pushes the parts in the limiting groove to the position adjustment mechanism, so that the parts can be automatically aligned and placed on the adjustment block, further improving the efficiency of part processing.

[0023] Furthermore, the width of the limiting groove is the same as the width of the conveyor belt, and the length of the limiting groove is the same as the length after the sliding parts of the plurality of adjustment blocks are closely attached to each other.

[0024] By adopting the above technical solution, in the present application, the sliding parts are closely attached to each other and then the push plate is slid to push the parts in the limiting groove onto the adjustment block, ensuring that the parts can be automatically aligned and placed on the adjustment block, further improving the efficiency of part processing.

[0025] Furthermore, a plurality of avoidance grooves are evenly formed on both sides inside the limiting groove.

[0026] By adopting the above technical solution, since the parts need to be moved to the next processing operation position by an external manipulator after the part pitch adjustment is completed, it is necessary to set the avoidance grooves to avoid the manipulator, ensuring the reliability of the part processing process.

[0027] Furthermore, the drive assembly includes a motor, a first pulley, a second pulley, a drive wheel and a belt. The motor is fixed on the side of the frame. The first pulley is installed on the output shaft of the motor. The second pulley is connected to the drive wheel. The first pulley and the second pulley are connected by a belt. The drive wheel is used to drive the conveyor belt.

[0028] By adopting the above technical solution, in the present application, the output shaft of the motor is transmitted to the conveyor belt through the combination of the belt pulleys and the belt, so as to drive the conveyor belt to run, ensuring the stability of part conveying.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. This application conveys parts through a conveying mechanism, pushes the parts from the conveyor belt to a spacing adjustment mechanism through a pushing mechanism, and then adjusts the spacing between the parts through the spacing adjustment mechanism.

[0031] 2. The adjusting blocks in this application are mutually clamped through a clamping portion and a clamping groove, enabling two adjacent adjusting blocks to be slidably connected to each other.

Detailed Description of the Specific Embodiment

[0039] The following Figure 1 - Figure 5 , further elaborates on this application in detail.

[0040] Since different processing procedures or processing equipment have different requirements for the part spacing, in the prior art, parts are usually manually transferred to a matrix for distance adjustment and then transferred to processing equipment for the next processing procedure. Since the spacing depends on manual adjustment, the efficiency is low, thus affecting the overall efficiency of automatic part processing. Therefore, the present application provides a variable-spacing device. Referring to Figure 1 , it includes a frame 1, a conveying mechanism 2, a pushing mechanism 3, and a spacing adjustment mechanism 4. The conveying mechanism 2, the pushing mechanism 3, and the spacing adjustment mechanism 4 are installed on the frame 1. The conveying mechanism 2 includes a conveyor belt 21 and a driving assembly 22. The driving assembly 22 is used to drive the conveyor belt 21 to run. The conveyor belt 21 runs in the direction of the arrow under the drive of the driving assembly 22. The pushing mechanism 3 is installed at the end of the running direction of the conveyor belt 21, and the spacing adjustment mechanism 4 is installed on one side of the pushing mechanism 3. Among them, the conveying mechanism 2 is used to convey a plurality of parts to the pushing mechanism 3, the pushing mechanism 3 is used to push a plurality of parts to the spacing adjustment mechanism 4, and the spacing adjustment mechanism 4 is used to adjust the spacing of a plurality of parts.

[0041] The implementation principle of the embodiment of the present application is as follows: Parts are conveyed through the conveying mechanism 2, the parts are pushed from the conveyor belt 21 to the spacing adjustment mechanism 4 through the pushing mechanism 3, and then the spacing of the parts is adjusted through the spacing adjustment mechanism 4. The spacing adjustment between parts can be realized without manual operation throughout the process, effectively improving the efficiency of automatic part processing.

[0042] As Figure 1 shown, the spacing adjustment mechanism 4 of the embodiment of the present application includes a first cylinder 41 fixed to the side of the frame 1 and seven adjustment blocks 42 connected to the output shaft of the first cylinder 41. The seven adjustment blocks 42 are slidably connected to each other. In the specific implementation process, the number of adjustment blocks 42 can be set according to the number of parts that need to be spaced adjusted at one time. One adjustment block 42 corresponds to one part. In the embodiment of the present application, seven adjustment blocks 42 are provided to simultaneously adjust the spacing of seven parts.

[0043] As Figure 2 shown, the spacing adjustment mechanism 4 of the embodiment of the present application further includes a first slide rail 43 and a plurality of first sliders 44. The first slide rail 43 is installed on the side of the frame 1. The plurality of adjustment blocks 42 are slidably connected to the first slide rail 43 through the plurality of first sliders 44, so that the plurality of adjustment blocks 42 slide along a direction parallel to the conveyor belt 21. In the specific implementation process, the number of first sliders 44 corresponds to the number of adjustment blocks 42, and the adjustment blocks 42 are installed on the first sliders 44. Through the first slide rail 43 and the first sliders 44, the adjustment blocks 42 slide along a direction parallel to the conveyor belt 21, so that the distance between the adjustment blocks 42 can be automatically adjusted, realizing automatic part spacing adjustment.

[0044] As Figure 3As shown, the adjusting block 42 of the embodiment of the present application includes a sliding portion 421, a clamping portion 422, a connecting portion 423, and a placing portion 424. A clamping groove 425 is formed on the side of the sliding portion 421 away from the first cylinder 41. The connecting portion 423 is used to be inserted into the clamping groove 425 of an adjacent adjusting block 42, and the clamping portion 422 is used to be clamped with the clamping groove 425 of the adjacent adjusting block 42 so that two adjacent adjusting blocks 42 are slidably connected to each other. The placing portion 424 is used to place the parts pushed by the pushing mechanism 3 to the spacing adjusting mechanism 4. By inserting and clamping the connecting portion 423 and the clamping portion 422 of the latter adjusting block 42 in two adjacent adjusting blocks 42 into the clamping groove 425 of the former adjusting block 42, two adjacent adjusting blocks 42 are slidably connected to each other. The length of the clamping groove 425 is the same as the sum of the length of the clamping portion 422 and the length of the connecting portion 423, so that when two adjacent adjusting blocks 42 slide to make the sliding portions 421 closely contact each other, the clamping groove 425 completely accommodates the clamping portion 422 and the connecting portion 423. In a specific implementation process, the parts are placed on the placing portion 424 of the adjusting block 42, and then the length of the connecting portion 423 of the latter adjusting block 42 inserted into the clamping groove 425 in two adjacent adjusting blocks 42 is adjusted by the cooperation of the first cylinder 41, the first slide rail 43, and the first slider 44, so as to adjust the distance between the parts placed on the placing portions 424 of the two adjusting blocks 42.

[0045] As Figure 4As shown in the figure, the pushing mechanism 3 of the embodiment of the present application includes a push plate 31, a second cylinder 32 fixed to the end of the frame 1, a second slider 34 connected to the output shaft of the second cylinder 32, and a second slide rail 33 installed on the top of the second cylinder 32. The end of the push plate 31 is slidably connected to the second slide rail 33 through the second slider 34, so that the push plate 31 slides in a direction perpendicular to the conveyor belt 21. One end of the push plate 31 away from the second slide rail 33 is provided with a limit groove 311. The limit groove 311 is aligned with the conveyor belt 21 when the push plate 31 is in the initial position, and the limit groove 311 is aligned with the placement portion 424 of the adjustment block 42 when the push plate 31 is in the pushed position. The width of the limit groove 311 is the same as the width of the conveyor belt 21, and the length of the limit groove 311 is the same as the length after the sliding portions 421 of several adjustment blocks 42 are closely attached to each other. In the specific implementation process, the conveyor belt 21 conveys the parts to the pushing mechanism 3. The parts conveyed by the conveyor belt 21 to the pushing mechanism 3 are accommodated through the limit groove 311. All the sliding portions 421 are closely attached to each other through the first cylinder 41, the first slide rail 43, and the first slider 44. When the number of parts accommodated in the limit groove 311 reaches the same as the number of adjustment blocks 42, the push plate 31 is moved in the direction close to the pitch adjustment mechanism 4 through the second cylinder 32, the second slide rail 33, and the second slider 34, so that the parts in the limit groove 311 are moved in the direction close to the pitch adjustment mechanism 4, so that the parts can be automatically aligned and placed on the placement portion 424 of the adjustment block 42. Then, the length of the connecting portion 423 of the latter adjustment block 42 inserted into the clamping groove 425 in two adjacent adjustment blocks 42 is adjusted through the first cylinder 41, the first slide rail 43, and the first slider 44, so as to adjust the distance between the parts placed on the placement portions 424 of the two adjustment blocks 42.

[0046] When the part pitch adjustment is completed, it is necessary to move it to the next processing step through an external manipulator. Therefore, a plurality of avoidance grooves 312 are evenly opened on both sides inside the limit groove 311 of the embodiment of the present application. The positions of the avoidance grooves 312 correspond to the positions where the manipulator grabs the parts, and the avoidance grooves 312 are provided to avoid the manipulator.

[0047] Such as Figure 5As shown in the figure, the drive assembly 22 of the embodiment of the present application includes a motor 221, a first pulley 222, a second pulley 223, a drive wheel 224, and a belt 225. The motor 221 is fixed to the side of the frame 1. The first pulley 222 is mounted on the output shaft of the motor 221. The second pulley 223 is connected to the drive wheel 224. The first pulley 222 and the second pulley 223 are connected by the belt 225. The drive wheel 224 is used to drive the conveyor belt 21. In the embodiment of the present application, the motor 221 is arranged below the frame 1, which can effectively save the overall occupied space of the device. The output shaft of the motor 221 is transmitted to the conveyor belt 21 through the combination of the pulley and the belt 225, so as to drive the conveyor belt 21 to run and ensure the stability of part conveying.
