Description

Technical Field

[0001] The technical solution relates to the technical field of feeding devices, and in particular to a multi-station turntable feeding device. Background Art

[0002] A feeding device is a device used to transport and transfer materials in a production automation system.

[0003] For example, Chinese patent CN206253507U discloses a device for continuous die processing with automatic transfer of energy by a manipulator, including a material rack, a manipulator arm, a guide rail, a manipulator arm, a die, a stamping device, a mis-delivery alarm system and a product conveyor belt. The product sheets are stacked on the material rack. After the manipulator sucks (grabs) the sheets, it slides on the guide rail to accurately convey the product sheets to the next station. Then the manipulator arm stops at the set empty position, and the stamping device works to stamp, completing a cycle. Through continuous cycles, the product is conveyed to the next station step by step, so as to realize the complete process of product stamping. The manipulator arm then puts the stamped product on the conveyor belt, and the conveyor belt conveys the product to the material box, completing the entire operation process and realizing fully automatic production. Figure 6 , the existing workpiece 100 is in the shape of a sheet structure.

[0004] The above-mentioned robot automatically transfers the equipment that can continuously punch the die. The existing sheet conveying is carried out by a conveyor belt in cooperation with a robot arm. The sheets are grabbed from the loading station to the conveyor belt in sequence, and the sheets are transported to the next station by the conveyor belt. This process requires multiple conveyor belts to cooperate in transportation. Due to the large overall structure of the conveyor belt, it occupies a large space and needs to be improved. Summary of the invention

[0005] In order to improve the problem of occupying a large space due to feeding with a conveyor belt structure, this technical solution provides a multi-station turntable feeding device.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A multi-station turntable feeding device comprises a machine base, the machine base is provided with a steering seat, the steering seat is rotatably connected to the machine base, the machine base is provided with a rotating drive component, the rotating drive component drives the steering seat to rotate circumferentially around a rotation axis, the steering seat is provided with a loading platform, the loading platform is provided with a clamping assembly, the clamping assembly is used to clamp the workpiece, the loading platform is slidably connected to the steering seat, the sliding direction of the loading platform is parallel to the rotation axis of the steering seat, the steering seat is provided with a sliding drive component, the sliding drive component drives the loading platform to slide downward so that the clamping assembly feeds material.

[0008] Through the above technical scheme, when the multi-station turntable feeding device is in normal use, the rotating drive member of the machine base drives the steering seat to rotate circumferentially around the rotating axis, and the steering seat drives the loading platform to rotate synchronously. Based on the installation of a clamping assembly on the loading platform, when the mobile clamping assembly is aligned with the loading station, a single workpiece is clamped from the loading station by driving the clamping assembly, and the steering seat operates again to drive the workpiece until it is aligned with the designated processing station. The sliding drive member of the steering seat can drive the loading platform to move downward toward the processing station, so that the workpiece of the clamping assembly can be accurately placed on the processing station, thereby realizing the workpiece feeding process, ensuring the accuracy and consistency of the workpiece during the feeding process, and then realizing continuous feeding through cyclic operation in a limited space, saving floor space and optimizing space utilization.

[0009] Preferably, the rotation driving member includes a driving motor and a cam divider arranged on the driving motor, the driving motor drives the steering seat to rotate through the cam divider, and the cam divider is used to control the rotation angle of the steering seat.

[0010] Through the above technical solution, the driving motor in the rotating driving member provides a power source, the cam divider is arranged on the driving motor, and the steering seat achieves high-precision angular positioning and indexing through the cam divider, thereby improving applicability. The cam divider converts the axial rotation of the steering seat into an intermittent rotation mode for feeding according to the preset angle parameters, so that the steering seat maintains a high positioning accuracy and repeatability while operating, thereby improving the accuracy of feeding the workpieces one by one.

[0011] Preferably, the material clamping assembly is provided in plurality, and the plurality of material clamping assemblies are evenly distributed circumferentially around the rotation axis of the steering seat.

[0012] Through the above technical solution, each clamping assembly corresponds to the feeding operation of processing a workpiece, and multiple clamping assemblies are evenly distributed on the steering seat, so that when the driving motor is controlled to rotate through the cam divider, the rotation angle is adapted to the circumferential distribution angle of the clamping assembly. Each clamping assembly can be aligned with the loading station and the processing station, and the workpiece clamping, feeding or moving processing steps can be performed at the same time, shortening the time required for the entire feeding, thereby improving production efficiency.

[0013] Preferably, the clamping assembly includes two clamping members and a clamping drive member arranged on the steering seat, the two clamping members are slidably connected to the loading platform, and the clamping drive member drives the two clamping members to slide closer to each other for clamping the workpiece.

[0014] Through the above technical solution, the distance between the two clamping members is adapted to the size of the workpiece, and the clamping drive member drives the clamping members on both sides to slide synchronously in relative directions. When the clamping members on both sides move closer, the clamping members on both sides apply clamping force to both sides of the workpiece one by one to ensure that the workpiece is firmly clamped and positioned. At this time, the clamping drive member stops to keep the workpiece in a clamped state.

[0015] When the workpiece is aligned with the processing station and the loading platform slides close to the processing station, the clamping drive drives the clamping members on both sides to slide in the opposite direction to release the workpiece so that it falls onto the processing station to complete the feeding, thereby realizing an efficient and continuous processing flow for the workpiece.

[0016] Preferably, each of the clamping members is provided with a positioning groove, and two positioning grooves are correspondingly provided on opposite end surfaces of the two clamping members, and the positioning grooves on both sides cooperate to allow the workpiece to be embedded and positioned.

[0017] Through the above technical scheme, based on the one-to-one correspondence of the positioning grooves opened on the opposite end faces of the two clamping members, the groove directions of the positioning grooves are opposite, and the groove widths of the positioning grooves are adapted to the thickness of the workpiece, so that when the clamping member slides, the two sides of the workpiece can be embedded in the positioning grooves on both sides one by one to achieve clamping, limiting the workpiece from detaching from the upper and lower sides, maintaining a stable clamping effect, and improving positioning accuracy. By supporting the workpiece with the lower end face of the positioning groove fixed, the clamping force applied by the clamping member to the workpiece is reduced, and the workpiece is prevented from being deformed by force, thereby reducing the loss cost of processing.

[0018] Preferably, the clamping member is provided with a clearance groove, and when the clamping assembly is clamped, the clearance groove is used to provide clearance.

[0019] Through the above technical solution, since the workpiece is in the shape of a layer plate, the size of the contact surface between the clamping member and the workpiece is reduced, so that the clamping member is in partial contact with the workpiece, further avoiding deformation loss to the workpiece.

[0020] Preferably, the clamping member further comprises a guiding portion, and the guiding portion comprises a guiding surface. When the clamping member is clamping, the inclined direction of the guiding surface is used to guide the workpiece to be embedded in the positioning groove.

[0021] Through the above technical solution, the inclination direction and inclination angle of the guide surface are both toward the clamping position of the workpiece, and the inclined surface of the guide surface guides the workpiece to embed into the positioning groove, so that the guide part cooperates to limit the workpiece from escaping from the clamp along the front and rear directions, further improving the accuracy and stability of workpiece positioning.

[0022] Preferably, the clamping member is provided with an extension portion, the extension portion is connected between the clamping member and the clamping driving member, and the clamping driving member drives the clamping member to slide through the extension portion.

[0023] Through the above technical solution, the extension parts are arranged one by one at the relative positions of the clamping members on both sides along the sliding direction, so that the clamping members on both sides are far away from each other and the spacing can be spliced ​​into a shape suitable for the workpiece. The clamping drive member drives the clamping member to slide by connecting with the extension part, thereby improving the sliding stability.

[0024] Preferably, the loading platform is provided with a guide sleeve, the guide sleeve is fixed to the upper end surface of the loading platform, the steering seat is provided with a guide shaft, and the guide sleeve is sleeved on the guide shaft for guiding the loading platform to slide.

[0025] Through the above technical solution, the through end of the guide sleeve slides freely along the guide shaft, the axis of the guide shaft is parallel to the sliding direction of the loading platform, and the guide sleeve and the guide shaft cooperate to guide the sliding path of the loading platform to avoid large swinging of the loading platform when sliding, enhance the sliding accuracy, and improve the stability of the sliding motion.

[0026] Preferably, the guide shaft is provided with a limiting portion, the limiting portion is located at a side of the guide shaft passing through the guide sleeve, and the guide shaft is provided with an elastic member, the elastic member is pressed between the limiting portion and the guide sleeve for buffering.

[0027] Through the above technical solution, the elastic member is adapted to the guide shaft and is sleeved on the guide shaft, and the two ends of the elastic member are respectively pressed against the corresponding end surfaces between the limit portion and the guide sleeve. When the loading platform slides downward in the vertical direction, the elastic member is compressed to provide a buffering effect, thereby reducing the impact and vibration caused by the direct contact between the guide shaft and the guide sleeve, and playing a protective effect to reduce wear, extend the service life, and maintain the stability of sliding.

[0028] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0029] 1. This technical solution is to provide a clamping assembly for clamping the workpiece on the loading platform, and the rotating driving member drives the steering seat to rotate circumferentially around the rotating axis to realize the movement of the workpiece. When the workpiece position is aligned with the processing station, the sliding driving member drives the loading platform to slide downward, the clamping assembly releases the workpiece to feed, and the loading platform moves up to prepare for the next feeding. The cyclic operation realizes continuous feeding, saves floor space, and optimizes space utilization.

[0030] 2. This technical solution evenly distributes multiple clamping components around the rotation axis of the steering seat, and multiple clamping components work together to shorten the time required for feeding, thereby improving production efficiency;

[0031] 3. This technical solution provides a guide sleeve on the loading platform, and a guide sleeve on the steering seat that is sleeved on the guide shaft for guiding sliding, so as to avoid large swings of the loading platform when sliding, enhance sliding accuracy, and improve the stability of sliding motion.

DETAILED DESCRIPTION

[0040] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0041] Example:

[0042] See also Figure 1 and Figure 2 A multi-station turntable feeding device includes a machine base 1, which is placed on a horizontal plane. A steering seat 2 is provided on the machine base 1, and the steering seat 2 is located above the machine base 1. The steering seat 2 is rotatably connected relative to the machine base 1, and the rotation axis of the steering seat 2 is arranged along the vertical direction. The machine base 1 is provided with a rotating drive member 3, and the rotating drive member 3 includes a driving motor 31 and a cam divider 32. The driving motor 31 is installed on one side of the machine base 1, and the output shaft of the driving motor 31 extends toward the machine base 1. The cam divider 32 is located in the machine base 1, and the steering seat 2 is arranged on the cam divider. The driving motor 31 drives the steering seat 2 to rotate circumferentially around the rotation axis through the cam divider 32. The cam divider 32 can control the rotation angle of the steering seat 2. In this embodiment, the cam divider 32 controls the rotation angle of the steering seat 2 to be a single rotation of 90°.

[0043] The steering seat 2 is provided with a loading platform 4, which is located on the side of the steering seat 2 away from the machine base 1. The loading platform 4 is slidably connected to the steering seat 2, and the sliding direction of the loading platform 4 is parallel to the rotation axis of the steering seat 2. The steering seat 2 is provided with a sliding drive 6, and the sliding drive 6 can be a cylinder or a motor. There are four sliding drives 6, each of which is located on the side of the loading platform 4 away from the steering seat 2. The four sliding drives 6 are evenly distributed on the loading platform 4 along the circumference of the rotation axis of the steering seat 2 and are fixed to the upper end surface of the loading platform 4. This embodiment shows that each sliding drive 6 is provided with a sliding screw, which is connected to the steering seat 2 and passes through the sliding drive 6, and the sliding drive 6 drives the loading platform 4 to slide up and down along the sliding screw.

[0044] The loading platform 4 is provided with a guide sleeve 12, and there are four guide sleeves 12. The four guide sleeves 12 are evenly distributed along the circumference of the rotation axis of the steering seat 2, and the distribution positions of the four guide sleeves 12 correspond one by one to the positions of the four sliding drive members 6, and are staggered with each other. The four guide sleeves 12 are all protruded and fixed on the end surface of the side of the loading platform 4 away from the steering seat 2; the steering seat 2 is provided with a guide shaft 13, and the length direction of the guide shaft 13 is parallel to the sliding direction of the loading platform 4. There are four guide shafts 13, and the positions of the four guide shafts 13 correspond one by one to the four guide sleeves 12. The four guide shafts 13 all extend toward the direction of the loading platform 4 and pass through the corresponding guide sleeves 12, and the guide sleeves 12 and the guide shafts 13 are nested and matched to realize the sliding of the guiding loading platform 4.

[0045] Each guide shaft 13 is provided with a limiting portion 14, which is located on the side of the guide shaft 13 passing through the guide sleeve 12, and the limiting portion 14 is fixed to the end face of the guide shaft 13 facing away from the steering seat 2. Each guide shaft 13 is also sleeved with an elastic member 15, and the elastic member 15 can be a reset spring. The two ends of the elastic member 15 are respectively pressed against the relative end faces between the limiting portion 14 and the guide shaft 13. The elastic force of the elastic member 15 makes the loading platform 4 tend to slide away from the limiting portion 14, so that when the sliding drive member 6 drives the loading platform 4 to slide in the direction away from the steering seat 2, the elastic member 15 is compressed so that the elastic force acts on the loading platform 4 to achieve buffering.

[0046] See also Figure 2 and Figure 3, a clamping assembly 5 is provided on the material loading platform 4, and there are multiple clamping assemblies 5. In this embodiment, a situation in which four clamping assemblies 5 are provided is shown. The four clamping assemblies 5 are evenly distributed circumferentially around the rotation axis of the steering seat 2, and each clamping assembly 5 is located on the side of the material loading platform 4 away from the steering seat 2; each clamping assembly 5 includes two clamping members 51 and a clamping drive member 52, the clamping drive member 52 is fixed to the upper end surface of the material loading platform 4, the clamping drive member 52 can adopt a pneumatic finger, the spacing between the two clamping members 51 matches the workpiece 100, the two clamping members 51 slide relative to the material loading platform 4, the sliding directions of the two clamping members 51 are both in the horizontal direction perpendicular to the rotation axis of the steering seat 2, and the clamping drive member 52 drives the two clamping members 51 to slide synchronously and then move closer to or away from each other, in this embodiment, a guide rail is fixed to the end surface of the material loading platform 4 close to the clamping member 51, the clamping member 51 is connected to a guide seat corresponding to the guide rail, and the guide rails are embedded in the guide seats one by one to realize the sliding guide of the clamping member 51.

[0047] See also Figure 4 and Figure 5 Each clamping member 51 is provided with an extension portion 11, which is located on the side of the corresponding clamping member 51 away from the loading platform 4, one end of the extension portion 11 is bolted to the clamping member 51, and the other end of the extension portion 11 is bolted to the clamping drive member 52. The setting of the extension portion 11 makes the clamping members 51 on both sides move away from each other, so that the distance between the two clamping members 51 is adapted to the length dimension of the workpiece 100.

[0048] Each clamping member 51 is provided with a positioning groove 7. Two positioning grooves 7 are correspondingly opened on the opposite end faces of the two clamping members 51. The opening direction of the positioning groove 7 is perpendicular to the rotation axis of the steering seat 2 and the sliding direction of the clamping member 51. The notch directions of the positioning grooves 7 on both sides are relatively arranged. The positioning grooves 7 on both sides are used to allow the workpiece 100 to be embedded; each clamping member 51 is also provided with a clearance groove 8. The clearance groove 8 is opened on one side of the clamping member 51 where the positioning groove 7 is provided. The clearance groove 8 makes the part of the clamping member 51 where the positioning groove 7 is provided be in the shape of a rod.

[0049] Both ends of the two positioning grooves 7 that are away from each other have guide parts 9, and the two guide parts 9 are both arranged on the clamping member 51. Each guide part 9 extends in a direction close to the clamping member 51 on the other side, and each guide part 9 has a guide surface 10, and the guide surface 10 is an inclined surface. The guide surfaces 10 between the two guide parts 9 face relative to each other, so that the inclined end surfaces of the guide surfaces 10 on both sides guide the workpiece 100 to be embedded in the two positioning grooves 7 for positioning, and the workpiece 100 rests against the lower groove wall of the positioning groove 7.

[0050] See also Figure 6 and Figure 7Each clamping drive 52 drives the corresponding two clamping members 51 away from each other, and the driving motor 31 drives the steering seat 2 to rotate through the cam divider 32. Based on the cam divider 32, the steering seat 2 is controlled to rotate at an angle so that each rotation angle matches the clamping assembly 5, and the clamping assembly 5 is driven to rotate so that it can be aligned with the loading station and the processing station. When the clamping assembly 5 is aligned with the loading station, the workpiece 100 is placed between the two clamping members 51, and the clamping drive 52 drives the clamping members 51 on both sides to approach each other. The workpiece 100 first contacts the guide surface 10, and the inclined surface of the guide surface 10 pushes the workpiece 100 to move, so that the two ends of the workpiece 100 can be positioned after being embedded in the positioning groove 7 one by one, and abut against the lower end surface of the positioning groove 7. The guide portion 9 and the positioning groove 7 respectively limit the workpiece 100 from escaping in the front-to-back direction and the up-and-down direction. When the clamping assembly 5 is aligned with the processing station, the sliding drive 6 drives the loading platform 4 to slide downward close to the processing station, the clamping assembly 5 releases the workpiece 100 so that the workpiece 100 falls onto the processing station, and the sliding drive 6 drives the loading platform 4 to slide upward and reset. At this time, the steering seat 2 rotates again toward the loading station to prepare for the next clamping.

[0051] Due to the continuous unidirectional rotation of the steering seat 2, some air pipes and conductive wires in the device become entangled and knotted, resulting in air circuit disconnection and electrical connection breakage and operation problems. This embodiment shows the situation where a rotary joint is provided on the loading platform. The rotary joint can adopt a circuit rotary joint and a pneumatic rotary joint. The pneumatic rotary joint can adapt the air pipe to the dynamic rotation system. The circuit rotary joint as a connector allows relative rotation of the conductive wire during connection and use, thereby maintaining the stability of the circuit connection and ensuring reliable signal transmission.

[0052] The specific working process of this program is as follows:

[0053] The technical solution is that a steering seat 2 is provided on the machine base 1, and a rotating drive member 3 drives the steering seat 2 to rotate circumferentially around the rotation axis, and the steering seat 2 drives the loading platform 4 to rotate synchronously. A plurality of clamping components 5 are installed on the loading platform 4, and the movable clamping component 5 is aligned with the loading station. The clamping drive member 52 drives the clamping member 51 to clamp a single workpiece 100, and the steering seat 2 is operated again to drive the workpiece 100 until it is aligned with the designated processing station. The sliding drive member 6 of the steering seat 2 can drive the loading platform 4 to move downward toward the processing station, so that the workpiece 100 can be accurately placed on the processing station, thereby realizing the feeding process of the workpiece 100, ensuring the accuracy and consistency of the workpiece 100 during the feeding process, and then realizing continuous feeding through cyclic operation in a limited space, saving floor space and optimizing space utilization.
