Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and in particular to a multi-directional variable-distance material transfer device. Background Technology

[0002] Traditional unloading claws use a fixed margin design or a unidirectional margin design, which can only pick up single pieces of products or single rows of products. The bidirectional variable-pitch structure, through orthogonally nested guide rails and indexing plates, enables simultaneous picking and unloading of entire trays with different margins from the test tray to the shipping tray along both the X and Y axes, thus accelerating the loading and unloading speed.

[0003] Chinese patent CN210175935U discloses a variable-pitch conveying mechanism. This mechanism can handle multiple support parts arranged in an array. The distance between these support parts in two vertical directions can be controlled by a first drive unit and a second drive unit, respectively. However, the second drive unit requires multiple power components, each of which only controls the distance between its two ends of the support parts, preventing all support parts from moving synchronously. Furthermore, the large number of these power components not only increases component costs but also increases the mechanism's weight, raising the risk of sagging and placing higher demands on the precision of motion control.

[0004] Therefore, it is necessary to improve the handling mechanism to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a multi-directional variable-pitch material handling device that can maintain an array arrangement of multiple material handling components during movement with fewer driving components and achieve higher movement accuracy.

[0006] The present invention achieves the above objectives through the following technical solution: a multi-directional variable-distance material transfer device, comprising a base assembly, a drive assembly, a movable assembly, and multiple material picking assemblies;

[0007] The base assembly includes a base plate, a shaft cylinder, four longitudinal guide rails, two guide rail seats, and a transverse stationary guide rail. The shaft cylinder is located at the upper center of the base plate. The four longitudinal guide rails are located at the four corners of the lower part of the base plate and extend in the front-back direction. The two guide rail seats are respectively located on the left and right sides of the lower surface of the base plate. The transverse stationary guide rail connects the two guide rail seats on the left and right sides. The base plate is provided with an array of several guide elongated holes.

Each transverse movable guide rail connects two longitudinal guide blocks that are opposite each other to the left and right. The transverse movable guide rail is parallel to and at the same height as the transverse stationary guide rail.

[0009] Each material handling assembly includes a material handling bracket, an upper roller, and a transverse guide block. The upper roller is located at the top of the material handling bracket and slides within the range of the guide elongated hole. The transverse guide block is fixed to the middle of the material handling bracket and slides in cooperation with the transverse movable guide rail or the transverse stationary guide rail. The material handling bracket of the middle row of material handling assemblies is provided with a longitudinal guide bar, and the material handling bracket of the other rows of material handling assemblies is provided with a lower roller. The longitudinal guide bar is provided with a longitudinal slot that matches the lower roller.

[0010] Specifically, the material handling components are arranged in an array of M rows and N columns, where M and N are both positive integers, M is an odd number, and N ≥ 3.

[0029] The present invention will be further described in detail below with reference to specific embodiments.

[0030] Example:

[0031] like Figure 1 As shown, a multi-directional variable-pitch material transfer device includes a base assembly 1, a movable assembly 2, and multiple material handling assemblies 3.

[0032] The material handling components 3 are arranged in an array of M rows and N columns, where M and N are both positive integers. In this embodiment, the multi-directional variable-pitch material handling device includes three rows and four columns of material handling components 3. The number of rows M is generally odd so that there can be material handling components 3 in the middle row, and the number of columns N ≥ 3.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the base assembly 1 includes a base plate 11, a shaft cylinder 12, four longitudinal guide rails 13, two guide rail seats 14, and a transverse stationary guide rail 15. The shaft cylinder 12 is located at the upper center of the base plate 11. The four longitudinal guide rails 13 are located at the four corners of the lower part of the base plate 11 and extend in the front-back direction. The two guide rail seats 14 are respectively located on the left and right sides of the lower surface of the base plate 11. The transverse stationary guide rail 15 connects the two guide rail seats 14 on the left and right sides. A plurality of elongated guide holes 111 are arranged in an array on the base plate 11. All the elongated guide holes 111 are arranged radially on the base plate 11, and each elongated guide hole 111 has one end pointing to the central axis of the shaft cylinder 12. The base plate 11 also has a plurality of hollow holes 112.

[0034] The substrate 11 serves as the fixed base for all components in the device. The shaft cylinder 12 is the connection point between the substrate 11 and the moving arm, and also the rotation center of the substrate 11. The guide elongated holes 111 are the movement limiting structures for the material picking components 3. Because all material picking components 3 need to maintain an array change, they should be proportionally closer to and further away from the central axis of the shaft cylinder 12. Therefore, all guide elongated holes 111 should be radially and arrayed. The perforated holes 112 do not contribute to the adsorption process itself; they are only used to reduce the weight of the substrate 11 without compromising its strength. They only need to be offset from the guide elongated holes 111.

[0035] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the movable component 2 includes four longitudinal guide sliders 21, two sets of longitudinal drive members 22, and two transverse movable guide rails 23. The four longitudinal guide sliders 21 cooperate with the four longitudinal guide rails 13 one by one. Each set of longitudinal drive members 22 drives two longitudinal guide sliders 21 that are opposite each other to move synchronously in the opposite direction. Each transverse movable guide rail 23 connects two longitudinal guide sliders 21 that are opposite each other to the left and right. The transverse movable guide rails 23 are parallel to and at the same height as the transverse stationary guide rails 15.

[0036] Both the transverse movable guide rail 23 and the transverse stationary guide rail 15 are left and right guiding components of the material handling assembly 3, and both can keep the left and right sides of the same row of material handling assemblies 3 collinear. The longitudinal drive component 22 is used to drive the longitudinal guide slider 21 to move along the longitudinal guide rail 13. The two longitudinal guide sliders 21 connected by the transverse movable guide rail 23 move synchronously, so the transverse movable guide rail 23 itself has the freedom of forward and backward movement. In this embodiment, each set of longitudinal drive components 22 consists of two cylinders installed back to back. In practical applications, linear drive components that can achieve reverse movement on both sides, such as bidirectional cylinders or double reverse screw motors, can be used instead.

[0037] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, each of the front and rear sides of the guide rail base 14 is provided with a limiting bolt 16 facing the longitudinal guide slider 21, and the lower surface edge of the substrate 11 is also provided with several blocks 17 that restrict the outermost movement position of the material picking component 3.

[0038] The depth of the limiting bolt 16 on the guide rail seat 14 is adjustable, thus controlling the closest distance between the longitudinal guide slider 21 and the guide rail seat 14. The stop block 17 blocks the outermost row of material-picking components 3. When the material-picking component 3 contacts the stop block 17, the multi-directional variable-pitch material transfer device is in its first working state. When all the material-picking components 3 approach each other, the longitudinal guide slider 21 approaches the end of the limiting bolt 16 until they contact, at which point the multi-directional variable-pitch material transfer device is in its second working state. Control of these two working states is not limited to these two methods; for example, blocking elements can be installed at both ends of the transverse movable guide rail 23, the transverse stationary guide rail 15, or the longitudinal guide rail 13.

[0039] like Figures 3 to 5 As shown, each material handling assembly 3 includes a material handling bracket 31, an upper roller 32, a transverse guide slider 33, a lifting cylinder 34, and a suction block 35. The upper roller 32 is located at the top of the material handling bracket 31 and slides within the range of the guide elongated hole 111. The transverse guide slider 33 is fixed to the middle of the material handling bracket 31 and slides in cooperation with the transverse movable guide rail 23 or the transverse stationary guide rail 15. The lifting cylinder 34 is fixed to the lower part of the material handling bracket 31 and drives the suction block 35 to rise and fall. The bottom of the suction block 35 is provided with several suction nozzles 351. The material handling bracket 31 of the middle row of material handling assemblies 3 is provided with a longitudinal guide bar 37, and the material handling bracket 31 of the other rows of material handling assemblies 3 is provided with a lower roller 36. The longitudinal guide bar 37 is provided with a longitudinal waist hole 371 that matches the lower roller 36. Each material handling bracket 31 is provided with a clearance hole 311 through which the longitudinal guide bar 37 passes.

[0040] In this embodiment, the material is picked up by suction, so the suction block 35 adsorbs the moving object through the suction nozzle 351. In practical applications, the suction block 35 can be replaced by a clamping material picking mechanism. The lifting cylinder 34 is used to control the distance between the suction nozzle 351 and the moving object. The cooperation between the longitudinal waist hole 371 and the longitudinal guide bar 37 keeps the picking components 3 in the same column collinear. The clearance hole 311 can also limit the movement of the longitudinal guide bar 37. The guide elongated hole 111 restricts the upper roller 32, ensuring that the movement of the picking component 3 in the front-back direction and the movement in the left-right direction must be completed simultaneously. This reduces the number of driving components and saves on parts input.

[0041] The working principle of the multi-directional variable-distance material transfer device is as follows:

[0042] 1. First, adjust the spacing between the material handling components 3: If a larger spacing is required, the longitudinal drive component 22 drives the longitudinal guide slider 21 to move outward until the outermost row of material handling brackets 31 contacts the stop block 17. At this time, the multi-directional variable distance material handling device is in the first working state. If a smaller spacing is required, the longitudinal drive component 22 drives the longitudinal guide slider 21 to move inward until the longitudinal guide slider 21 contacts the end of the limit bolt 16. At this time, the multi-directional variable distance material handling device is in the second working state.

[0043] 2. The moving arm adjusts the horizontal position and rotation angle of the multi-directional variable distance material transfer device from the shaft cylinder 12, so that the suction block 35 approaches the moving object and the suction nozzle 351 reaches a position slightly above the moving object.

[0044] 3. The lifting cylinder 34 drives the suction block 35 to descend, causing the lower end of the suction nozzle 351 to attach to the moving object, thereby sucking up multiple moving objects.

[0045] 4. The moving arm then drives the multi-directional variable-pitch material transfer device to the target area, and the suction nozzle 351 stops suctioning, allowing the moving objects to fall to their respective target positions.

[0046] This multi-directional variable-pitch material handling device can maintain the array arrangement of multiple material handling components 3 during movement with fewer driving components, which not only saves on parts costs but also improves movement accuracy.

[0047] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
