Description

Technical Field

[0001] This utility model relates to the field of precision motion control technology, specifically a high-speed XY direction motion handling structure. More particularly, it relates to a high-speed XY dual-degree-of-freedom handling structure with a small turning radius, driven by a single motor, achieved through the joint constraint of two planar cam mechanisms. Background Technology

[0002] In the field of automated equipment, high-speed transport structures are key components for achieving fast and accurate workpiece handling. Traditional transport structures often use motor-driven lead screws or rack and pinion transmissions, combined with guide rails to achieve linear motion. However, to accommodate the high-speed and precision movements such as sorting, handling, and assembly in automated equipment, and considering the current demands for high-speed operation, reduced equipment costs, and smaller turning radii in non-standard equipment, traditional transport structures have some shortcomings:

[0003] 1. Large space occupation: In order to achieve multi-directional movement, multiple motors and transmission mechanisms are usually required, resulting in a complex overall structure and large space occupation, which is not conducive to the miniaturization and compact design of the equipment.

[0004] 2. Large turning radius: In high-speed handling, traditional handling structures often require a large turning radius when making curved movements to avoid impact and vibration, which limits the application of the equipment in confined spaces.

[0005] 3. High cost: Multi-motor drive and complex transmission mechanism increase the manufacturing and maintenance costs of the equipment, as well as the energy consumption of the equipment.

[0006] 4. Simple motion patterns: Traditional handling structures are unable to achieve complex motion patterns, such as sinusoidal or cosine acceleration motion, and cannot meet the needs of some special processes.

[0007] Therefore, there is an urgent need for a new type of material handling structure that can achieve high-speed, complex curve handling in a small space, while having a small turning radius and low cost. Utility Model Content

[0008] The purpose of this utility model is to provide a high-speed XY direction motion handling structure to solve the problems mentioned in the background art, such as large space occupation, large turning radius, high cost, and simple motion law of traditional handling structures when performing high-speed and precise actions such as sorting, handling, and assembly in automated equipment.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a high-speed XY direction moving conveying structure, comprising a support frame and an XY slide table at its top; the support frame includes a horizontally arranged frame base plate with two frame fixing seats on its top surface, and two vertical frame support columns are arranged through the two frame fixing seats. Each frame support column has a frame fixing block at its top. The two frame fixing blocks share a vertical frame mounting plate on the front side of the two frame support columns. A main drive cam groove is horizontally arranged near the top on the front side of the frame mounting plate. A servo motor is arranged near the lower right corner on the rear side of the frame mounting plate, and the servo motor has a drive mechanism on the front side of the frame mounting plate. The gear, along with the drive gear and the main drive cam groove, forms an XY slide. The XY slide includes a vertically arranged bottom slide with a drive rack at its bottom edge that meshes with the drive gear. Near the left end of the front side of the bottom slide, two X-guide rails are arranged horizontally, one above the other. These two X-guide rails are connected by a slider to form an X-axis slide that can slide along its axis. On the front side of the X-axis slide, two Y-guide rails are arranged vertically, one to the left and one to the right. These two Y-guide rails are connected by a slider to form a Y-axis slide that can slide along its axis. A main cam follower, which can be embedded in the main drive cam groove, is located at the top of the Y-axis slide beyond the top edge of the X-axis slide. A gripper mechanism is located at the bottom end of the Y-axis slide.

[0010] Preferably, a horizontal frame middle plate is provided at the middle position of the two frame support columns, and a horizontal frame top plate is provided near the top. A frame support plate is provided between the frame middle plate and the frame bottom plate and between the two frame support columns.

[0011] Preferably, a speed reducer is provided on the rear side of the frame mounting plate near the lower right corner, a servo motor is provided on the rear side of the speed reducer, and a drive gear is provided on the front side of the frame mounting plate.

[0012] Preferably, an auxiliary cam follower is provided at the middle position of the Y-axis slide plate, and a strip-shaped through hole is vertically provided at the corresponding position of the auxiliary cam follower on the Y-axis slide plate. An auxiliary cam groove is provided between the two X-axis guide rails on the bottom slide plate, and the auxiliary cam follower is embedded in the auxiliary cam groove.

[0013] Preferably, the gripper mechanism includes a horizontal gripper mounting plate, and gripper cylinders are arranged opposite each other on the bottom surface of the gripper mounting plate. Clamping claws are arranged in pairs on the gripper cylinders.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model controls the movement speed of the follower by using an auxiliary cam groove, which greatly reduces the turning radius of the motion curve. Compared with the traditional single cam groove drive, this structure can realize the reversing operation in a smaller space, avoiding the waste of equipment space caused by excessive turning radius.

[0016] 2. This utility model employs a servo motor-driven rack and pinion mechanism, combined with an XY bidirectional slide table, to achieve high-speed and high-precision material handling. Furthermore, by optimizing the cam groove curve design, complex motion patterns can be achieved to meet the needs of different processes.

[0017] 3. This structure requires only one servo motor to drive the movement of the entire XY slide, reducing the number of motors and the complexity of the transmission mechanism, thus lowering the manufacturing and maintenance costs of the equipment; at the same time, the simplified structure also makes the assembly and maintenance of the equipment more convenient.

[0018] 4. This utility model effectively reduces the space occupied by the equipment by converting the lateral movement into a bidirectional XY movement mode; the compact structural design allows the equipment to better adapt to application scenarios in narrow spaces and improves space utilization.

[0019] 5. This invention, by modifying the cam groove curve, can achieve various complex follower motion laws, such as sinusoidal acceleration motion or cosine acceleration motion. This flexibility allows the equipment to adapt to different handling needs, improving its versatility and adaptability.

[0020] In summary, the high-speed XY direction motion transport structure of this utility model patent, through innovative cam groove design and XY slide structure, realizes transport of materials with small turning radius, high speed, and complex curves. It has the advantages of simple structure, low cost, high space utilization, flexible motion law and high stability, and has great economic value and application prospects.

Detailed Implementation

[0030] This utility model provides a high-speed XY direction motion handling structure, which is particularly suitable for non-standard automated equipment such as material sorting, handling, and assembly that require high-speed planar trajectory motion; it includes a support frame 1, and an XY slide table 2 is provided at the top of the support frame 1.

[0031] The supporting frame 1 includes a horizontally arranged frame base plate 101. Two frame fixing seats 102 are provided on the top surface of the frame base plate 101. Two vertical frame support columns 103 are provided through the two frame fixing seats 102. A horizontal frame middle plate 104 is provided at the middle position of the two frame support columns 103, and a horizontal frame top plate 105 is provided near the top. A frame support plate 106 is provided between the frame middle plate 104 and the frame base plate 101, between the two frame support columns 103. A frame is provided at the top of each frame support column 103. The frame fixing block 107 has two frame fixing blocks 107, and two vertical frame mounting plates 108 are jointly provided on the front side of the two frame support columns 103. The front side of the frame mounting plate 108 has a main drive cam groove 109 horizontally provided near the top. The rear side of the frame mounting plate 108 has a reducer 110 near the lower right corner. The rear side of the reducer 110 has a servo motor 111, and the front side of the reducer 110 has a drive gear 112. The XY slide table 2 is jointly provided by the drive gear 112 and the main drive cam groove 109.

[0032] The XY slide table 2 includes a vertically arranged bottom slide plate 201. A drive rack 202, meshing with the drive gear 112, is located at the bottom edge of the bottom slide plate 201. Two horizontally arranged X-axis guide rails 203 are positioned side-by-side on the front side of the bottom slide plate 201, and an X-axis slide plate 204, which can slide along its axial direction, is connected to the two X-axis guide rails 203 via a slider. Two horizontally arranged Y-axis guide rails 205 are vertically arranged on the front side of the X-axis slide plate 204, and a Y-axis slide plate 206, which can slide along its axial direction, is connected to the two Y-axis guide rails 205 via a slider. A main cam follower 207 is located at the top of the Y-axis slide plate 206, extending beyond the top edge of the X-axis slide plate 204. The main cam follower 207 is embedded in the main drive cam groove 109 and extends along its axial direction. Its axial sliding; an auxiliary cam follower 208 is provided at the middle position of the Y-axis slide plate 206, and a strip-shaped through hole is vertically provided at the corresponding position of the auxiliary cam follower 208 on the Y-axis slide plate 206. An auxiliary cam groove 209 is provided between the two X-axis guide rails 203 on the bottom slide plate 201. The auxiliary cam follower 208 is embedded in the auxiliary cam groove 209 and assists the Y-axis slide plate 206 to move axially along the Y-axis guide rail 205. A gripper mounting plate 210 is horizontally provided at the bottom end of the Y-axis slide plate 206. A gripper cylinder 211 is provided opposite to each other on the bottom surface of the gripper mounting plate 210. A pair of clamping claws 212 are provided on the gripper cylinder 211. The workpiece is clamped and assisted in transportation by the cooperative use of the clamping claws 212.

[0033] When in use, when the main cam follower 207 moves horizontally along the main drive cam groove 109, the auxiliary cam groove 209 cannot drive the Y-axis slide plate 206 to move vertically, so it can only move horizontally under the combined action of the two. At this time, the positional relationship of the XY slide is relatively fixed.

[0034] When the main cam follower 207 converts to a vertical motion pattern along the main drive cam groove 109, the auxiliary cam groove 209 will drive the Y-axis slide plate 206 to move in the same direction as the main drive cam groove 109. At this time, the main drive cam groove 109 controls the motion curve of the Y-axis slide plate 206, and the auxiliary cam groove 209 controls the motion speed of the Y-axis slide plate 206. The two work together to achieve vertical motion.

[0035] Because the auxiliary cam groove 209 is introduced to control the Y-axis movement speed of the follower, the turning radius of the motion curve can be greatly reduced, and at the same time, the motion action perpendicular to the direction of the main drive rack can be realized.

[0036] Although embodiments of the present invention have been shown and described, it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, it will be understood by those skilled in the art that all other embodiments obtained by making various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention and without creative effort are within the scope of protection of the present invention.
