Description

Technical Field

[0001] The utility model relates to the technical field of parts processing equipment, in particular to a parts loading and unloading mechanism. Background Art

[0002] All kinds of mechanical equipment are composed of parts. Parts are generally small in size. In order to facilitate placement and transportation, parts are usually placed in an array on pallets. Pallets can be stacked up and down to achieve large-scale transportation of parts. However, when parts are processed, they are processed one by one, which means that parts need to be loaded and unloaded one by one.

[0003] Usually, loading and unloading mechanisms are used to load and unload parts. The loading and unloading mechanisms include a lifting device and a manipulator. The lifting device lifts the tray into the working range of the manipulator, and the manipulator grabs the parts. However, after the parts on the tray are loaded and unloaded, the tray needs to be replaced before the parts on the next tray can be loaded and unloaded. This causes the manipulator to have idle time, reducing the efficiency of loading and unloading. Utility Model Content

[0014] The clamping block is fixedly connected to the clamping drive member and can approach or move away from the material tray along a first direction under the drive of the clamping drive member.

[0015] When the tray needs to be clamped, the clamping drive member drives the clamping block to move toward the tray, and the tray is clamped between the two clamping components. At this time, the tray can be positioned to improve the stability of the tray.

[0016] Furthermore, the positioning device further includes a separation component, the separation component and the clamping component are correspondingly arranged, and the separation component is used to separate the uppermost tray on the placement table from the other trays.

[0035] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0036] See attached Figure 1 As shown, the parts loading and unloading mechanism of the utility model is used for loading and unloading parts, and the parts are placed on the tray 4. The loading and unloading mechanism includes a lifting device, a positioning device 2 and a handling device 3. The lifting device can transport two trays one by one into the working range of the positioning device 2. The positioning device 2 is used for positioning a tray 4, and the handling device 3 is used for handling the parts on the tray 4.

[0037] There are two lifting devices spaced apart along the first direction, each of which includes a lifting table 111 that can be raised and lowered, on which a material tray 4 can be placed, and the placing tables 111 extend from both ends of the material tray 4 along the first direction (X direction). The positioning device 2 is located above the lifting device, and the positioning device 2 includes a positioning table 21, which can reciprocate between the two lifting devices along the first direction, and the positioning table 21 is provided with a positioning hole 211 through which the material tray 4 passes, and the positioning table 21 is fixed with clamping assemblies 23 located on both sides of the positioning hole 211 in the first direction and capable of clamping the material tray 4. The transport device 3 is located above the positioning device 2, and the transport device 3 is used to take and place parts on the material tray 4 after being positioned by the positioning device 2.

[0038] In this embodiment, a placement table 111 of a lifting device is used to place a tray 4 with parts. After the handling device 3 takes away all the parts on the tray 4, another lifting device is used to place an empty tray 4. The handling device 3 can continue to take and place the parts on the tray 4 with parts. The setting of two lifting devices can realize the rapid unloading of the empty tray 4, and the handling device 3 will always be in working state, improving efficiency. At the same time, in this embodiment, a positioning device 2 is added to position a tray 4, which is convenient for the precise handling of the handling device 3.

[0039] The two lifting devices are lifting device 1 11 and lifting device 2 12. Lifting device 1 1 is stacked with material trays 4 in the vertical direction (Z direction), and parts are swung in the material trays 4 on lifting device 1 1. During the lifting process, lifting device 1 1 passes the top material trays 4 through the positioning holes 211 one by one to reach the clamping position of the clamping assembly 23. At this time, the clamping assembly 23 clamps the top material tray 4, and the handling device 3 starts to carry the parts. When the handling device 3 carries the last part, the positioning platform 21 moves to the top of lifting device 2 12, and then the clamping assembly 23 releases the empty material tray 4 and places the empty material tray 4 on lifting device 2 12. Then the positioning platform 21 continues to move to the top of lifting device 1 11 to clamp the next material tray 4.

[0040] See attached Figure 2 As shown, each of the clamping assemblies 23 includes a clamping drive 231 and a clamping block 232. The clamping drive 231 is fixed on the positioning platform 21. The clamping block 232 is fixedly connected to the clamping drive 231 and can approach or move away from the material tray 4 along a first direction under the drive of the clamping drive.

[0041] The clamping drive 231 can be a cylinder, which can drive the clamping block 232 to move back and forth along a straight line. The positioning hole 211 is larger than the tray 4, that is, the tray 4 can be completely embedded in the positioning hole 211. When the tray 4 needs to be clamped, the clamping drive 231 drives the clamping block 232 to move toward the tray 4, and the tray 4 is clamped between the two clamping assemblies 23. At this time, the tray 4 can be positioned to improve the stability of the tray 4.

[0042] See attached Figure 4 As shown, the clamping block 232 includes a fixing portion 232a, which is vertically arranged and fixedly connected to the clamping driving member 231, and the fixing portion 232a can abut against the side of the material tray 4. A horizontal lifting portion 232b extending along the first direction is fixed to the lower end of the fixing portion 232a, and the horizontal lifting portion 232b can extend under the material tray 4 to lift the material tray 4.

[0043] The tray 4 includes a placement portion and surrounding extensions, the upper end surface of the extension is lower than the upper end surface of the placement portion, and the lower end surfaces of the two are at the same height, so when the trays 4 are stacked, there will be a gap between the extensions. The horizontal lifting portion 232b will be inserted from the gap to lift the tray 4.

[0044] See attached Figure 4As shown, the clamping block 232 further includes a guide portion 232c, which is arranged on both sides of the fixing portion 232a in the second direction, and the guide portion 232c extends along the first direction, and the two guide portions 232c form a flared structure on one side away from the fixing portion 232a. The guide portion 232c can clamp the side of the material tray 4 on one hand, and on the other hand, the flared structure facilitates the introduction of the material tray 4. The flared structure means that each guide portion 232c is provided with an inclined surface on the side away from the fixing portion 232a, and the inclined surfaces of the two guide portions 232c form a flared structure.

[0045] In one embodiment, see the attached Figure 2 and attached Figure 3 As shown, the positioning device 2 further includes a separation component 24 , and the separation component 24 and the clamping component 23 are correspondingly arranged, and the separation component 24 is used to separate the topmost material tray 4 on the placement table 111 from the other material trays 4 .

[0046] Because the trays 4 are stacked on the lifting device 11, the trays 4 are plugged together at the beginning. The uppermost tray 4 can not be completely separated from the lower tray 4 by only relying on the clamping assembly 23 to clamp the uppermost tray 4. In this way, the positioning plate cannot move along the X direction or may drive the lower tray 4 to move. Therefore, a separation assembly 24 is provided to ensure that the uppermost tray 4 will not adhere to the lower tray 4.

[0047] The separation assembly 24 includes a separation drive member 241 and a separation block 242. The separation drive member 241 is fixed to the fixed portion 232a of the clamping block 232. The separation block 242 is fixedly connected to the separation drive member 241. The separation block 242 can move up and down under the drive of the separation drive member 241. The separation block 242 can extend under one of the material trays 4 and pull the material tray 4 upward to separate the material tray 4 from the other material trays 4. The separation block 242 is located below the fixed portion 232a and can move upward to the top of the horizontal lifting portion 232b.

[0048] Initially, the separation block 242 is at the same height as the upper end surface of the horizontal lifting portion 232b and is inserted synchronously from the gap. Then the separation block 242 moves upward, driving the tray 4 to move upward by a certain distance (1-3 cm). At this time, since the horizontal lifting portion 232b will limit the position of the next tray 4, the uppermost tray 4 moves upward by the moving distance, and the two adjacent trays 4 are separated without adhesion.

[0049] See attached Figure 4As shown, the fixing portion 232a is provided with a clearance groove 2321a for the separation block 242 to move upward. The clearance groove 2321a provides space for the separation block 242 to move upward and limits the upward movement distance of the separation block 242. The clearance groove 2321a is provided in the middle of the fixing portion 232a, that is, the fixing portion 232a is symmetrical with respect to the separation block 242.

[0050] In one embodiment, the positioning device 2 further includes a detection component 25, which is used to detect the material tray 4 at the positioning hole 211. The detection component 25 includes a through-beam sensor, and the transmitting end and the receiving end of the through-beam sensor are respectively fixed on the positioning platform 21. The through-beam sensor is connected to the separation drive 241 and the clamping drive 231. When it is detected that a material tray 4 is in place, the clamping component 23 and the separation component 24 start to work and clamp the uppermost material tray 4. A through-beam light extending along the first direction is formed between the transmitting end and the receiving end. When the through-beam light is blocked, a material tray 4 enters the surface.

[0051] The positioning device 2 and the lifting device also include a horizontal linear module 22 and a vertical linear module 112 corresponding to the positioning platform 21 and the placement platform 111. The positioning platform 21 and the placement platform 111 are connected to the corresponding linear modules. The horizontal linear module 22 drives the positioning platform 21 to make linear reciprocating movements along the X direction, and the vertical linear module 112 drives the placement platform 111 to make linear reciprocating movements along the Z direction. The linear module is a prior art and can be a structure such as a screw rod, a nut seat assembly or a linear cylinder. According to the set direction, the linear movement is driven in different directions.

[0052] See attached Figure 1 As shown, the handling device 3 includes an adsorption component 31, which includes multiple adsorption nozzles. The adsorption component 31 can adsorb multiple parts at the same time. The adsorption component 31 can move horizontally along the second direction (Y direction) and can move up and down under the drive of the horizontal driving member 32. The horizontal driving member 32 drives a slider to move back and forth along the Y direction. A vertical driving member 33 is fixed on the slider. The vertical driving member 33 drives a lifting block to move up and down. The adsorption component 31 is fixed on the lifting block.
