Description

Technical Field

[0001] This invention relates to the field of machinery, and more particularly to a pallet switching and material flipping mechanism. Background Technology

[0002] In manufacturing production lines, materials flow within pallets, typically encountering the following scenarios: Scenario 1: Often, it's necessary to work on both the front (A) and back (B) of a material simultaneously. That is, after completing work on front A, work on back B is required, and after completion, the material needs to be transferred to the next process with front A. This necessitates flipping, working on, and then flipping again, as seen in the pin height measurement station on the back of a surface-mount circulator in the telecommunications industry. Scenario 2: Materials need to be transferred from pallet C to pallet D, such as in the flatness station of isolators, where isolators in the transfer pallet need to be flipped to the testing pallet.

[0003] To accomplish the above tasks, manual conversion and flipping are generally used, which results in low efficiency (slow speed) and low accuracy (inaccurate alignment between pallet D9 and pallet C8), and poses safety hazards to materials and personnel (materials can easily fall out if not gripped tightly). Summary of the Invention

[0004] The purpose of this invention is to provide a simple, reliable, and safe mechanism for switching work objects between pallets A and B, or for flipping the work objects from side to side, in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a pallet conversion and material flipping mechanism, comprising a mechanism mounting plate, a pallet gripping mechanism, and a power mechanism providing power to the pallet gripping mechanism. The power mechanism is mounted on the mechanism mounting plate. The pallet gripping mechanism includes a clamping mechanism, a top plate mechanism, a pallet gripping mechanism transition block, a pallet C detection switch, a detection switch fixing block, and a pallet positioning seat. The clamping mechanism comprises two sets, both sets of which are fixedly mounted on the pallet positioning seat. The top plate mechanism also comprises two sets, located at the front and rear ends of the pallet positioning seat. The pallet gripping mechanism transition block is located on the side of the pallet gripping mechanism closest to the power mechanism. One end of the transition block is connected to screw hole A via a screw, and the other end is connected to a rotating shaft via a screw, its function being to transmit the rotational power of the rotating shaft to the pallet gripping mechanism. The detection switch fixing block is located on the side of the pallet gripping mechanism furthest from the power mechanism, and the pallet C detection switch is located outside the detection switch fixing block.

[0006] As a preferred technical solution: the power mechanism includes a bearing housing, a motor, a reducer, a gear, and a rotating shaft, wherein the motor, the reducer, and the gear are connected in sequence, the two ends of the rotating shaft are respectively connected to the gear and the gripping mechanism, and the bearing housing is disposed outside the rotating shaft.

[0007] As a preferred technical solution: the buckle mechanism includes hooks and hook guide blocks arranged symmetrically at both ends in sequence. The hook guide block is provided with a square through hole. It also includes a left pull rod and a right pull rod passing through the square through hole. A cylinder A is provided between the left pull rod and the right pull rod.

[0008] As a preferred technical solution: the top plate mechanism includes a top head, a guide sleeve and a cylinder B arranged in sequence.

[0009] As a preferred technical solution: the pallet positioning seat is provided with pallet limiters and limit strips around its perimeter, and is provided with several screw holes.

[0010] The mechanism of this invention can realize pallet switching and material flipping, and can also achieve self-locking in the event of power failure to prevent rotation and protect the safety of materials and personnel.

[0011] Compared with the prior art, the advantages of the present invention are: the structure of the present invention can automatically realize the pallet transfer of the work object or the flipping of the work object, and the structure is simple, low cost, safe and highly reliable.

Implementation

[0022] The invention will now be further described with reference to the accompanying drawings. Example:

[0023] See Figure 1 A pallet transfer and material flipping mechanism includes a mechanism mounting plate 1, a bearing seat 2, a motor 3 with a brake, a reducer 4, a gear 5, a rotating shaft 6, and a pallet gripping mechanism 7, wherein...

[0024] In this embodiment, the structure of the gripping mechanism 7 is as follows: Figure 2 , Figure 3 and Figure 4 As shown, it includes a tray clamping mechanism 7-1, a tray top mechanism 7-2, a tray gripping mechanism transition block 7-3, a tray C detection switch 7-4, a detection switch fixing block 7-5, and a tray positioning seat 7-6;

[0025] The structure of the latching mechanism 7-1 is as follows: Figure 5 As shown, the device includes a hook 7-1-1, a hook guide block 7-1-2, a left pull rod 7-1-3, a circular pivot pin 7-1-4, a cylinder A7-1-5, a square pivot pin 7-1-6, a pivot pin pressure plate 7-1-7, a right pull rod 7-1-8, screws A7-1-9 and B7-1-10, etc. The latching mechanism 7-1 consists of two sets, which are installed in the screw holes C7-6-5 of the tray positioning seat 7-6 by screws A7-1-9.

[0026] The structure of the top plate mechanism 7-2 is as follows: Figure 6 As shown, it includes a top head 7-2-1, a guide sleeve 7-2-2, a screw C7-2-3, a cylinder B7-2-4, and a screw D7-2-5.

[0027] The structure of the tray positioning seat 7-6 is as follows: Figure 7 As shown, it includes a tray limiter 7-6-1, screw hole A7-6-2, screw through hole 7-6-3, screw hole B7-6-4, screw hole C7-6-5, and a limit strip 7-6-6.

[0028] The structure of the tray C8 is as follows Figure 8 As shown, two tray C notches 8-1 are symmetrically arranged on each of the two opposite sides of tray C8; the structure of tray D9 is as follows. Figure 9 As shown, two tray D notches 9-1 are symmetrically arranged on each of the two opposite sides of tray D9.

[0029] The top plate mechanism 7-2 consists of two sets, which are fixed by screws C7-2-3 screwed into screw holes C7-6-5. The front and rear positions of the top plate mechanism 7-2 are precisely limited by the limiting strip 7-6-6. The end of the top head 7-2-1 has a threaded hole that cooperates with the rod end of the cylinder B7-2-4. The inside of the guide sleeve 7-2-2 is a rectangular through hole, which provides guidance and anti-rotation functions. When the cylinder B7-2-4 retracts, it drives the top head 7-2-1 to retract. The top head 7-2-1 releases the tray D notch 9-1. At this time, the tray D9 can be taken out from the normal position under the restriction of the tray limiting 7-6-1. When the cylinder 7-2-7 extends, the top head 7-2-1 inserts into the tray D notch 9-1 and tightly fastens the tray 9 into the tray positioning seat 7-6.

[0030] In this embodiment, the hook guide block 7-1-2 has a rectangular through hole inside, which cooperates with the left pull rod 7-1-3 and the right pull rod 7-1-8 to provide guidance and anti-rotation functions. When the cylinder A7-1-5 extends, it drives the hook 7-1-1 to extend. At this time, the hook 7-1-1 releases the notch tray C8-1 on the tray C8. At this time, the tray C8 can be taken out from the normal position under the restriction of the tray limit 7-6-1. When the cylinder A7-1-5 retracts, the hook 7-1-1 locks the tray C notch 8-1 on the tray C8, and tightly holds the tray C8 and the tray D9 together and sticks them to the tray positioning seat 7-6.

[0031] The gripping mechanism 7 grips and releases trays C8 and D9, specifically as follows:

[0032] The two sets of top heads 7-2-1 cooperate with the tray D notch 9-1 to achieve the gripping and releasing of the tray D9;

[0033] The four sets of hooks 7-1-1 cooperate with the notch 8-1 of tray C to grasp and release tray C8;

[0034] Generally, the materials used in the production line are placed in the tray C8. With the overall flipping of the gripping mechanism 7, the materials in the tray C8 can be transferred to the tray D9.

[0035] In this embodiment, the entire mechanism is fixed by the mechanism mounting plate 1. When the production line pallet C8 flows to this process, the gripping mechanism 7 and the pallet D9 are brought together by the action of the top head 7-2-1. Driven by the motor 3, through the reducer 4, gear 5, and rotating shaft 6, the gripping mechanism 7 and the pallet D9 are rotated downwards, and the entire mechanism is engaged with the pallet C8. At this time, the hook 7-1-1 clamps the pallet C notch 8-1 on the pallet C8, tightly holding the pallet C8 and the pallet D9 together. The motor 3 drives the gripping mechanism 7 to rotate 180° again, transferring the material into the pallet D9 (at this time, the material is also flipped to its front and back). The hook 7-1-1 is released again, the pallet C8 is removed, and subsequent work such as material processing can be performed.

[0036] Because the motor 3 has a built-in brake, this mechanism can hold the motor tightly when the power is off or rotation is not required, thereby preventing the gripping mechanism 7 from rotating or spinning due to external forces, effectively ensuring the safety of materials and personnel. This mechanism can be combined with the CETC brand circulator pin height detection equipment ZZ202206-3-H type automated frame, as well as other automated production lines in various industries that require pallet switching and material flipping, to perfectly realize the automated operation of pallet switching of work objects or the front and back flipping of work objects.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
