Description

Technical Field

[0001] The utility model relates to the technical field of suction mechanisms, in particular to a scissor-type frame variable-distance suction device. Background Art

[0002] Photovoltaic modules are typically assembled from a photovoltaic substrate and four frames. During the manufacturing process, multiple frames need to be handled, and this may require a suction mechanism with multiple suction cup assemblies arranged side by side. Because the width of the frames varies, the spacing between the suction cup assemblies varies. If the frame is narrow, the initial position on the removal jig will be closer, so the suction cup assemblies should also be closer; conversely, the suction cup assemblies should be farther apart.

[0003] Chinese patent CN214081495U discloses an equally spaced variable-distance adsorption mechanism that utilizes a power mechanism to drive sliding adsorption mounting blocks toward or away from each other, thereby causing the extrusion portion of each sliding adsorption module to move between the first and second stop portions of the corresponding sliding connection block. When all extrusion portions rest against their corresponding first stop portions, the spacing between the adsorption cylinders reaches the same minimum value; when all extrusion portions rest against their corresponding second stop portions, the spacing between the adsorption cylinders reaches the same maximum value. Based on this principle, the variable-distance mechanism only has two stable positions and cannot flexibly adapt to various sizes.

[0004] Therefore, it is necessary to improve the variable distance suction mechanism to solve the above problems. Summary of the Invention

[0025] The present invention will be further described in detail below with reference to specific embodiments.

[0026] Example:

[0027] like Figure 1 As shown, the present invention provides a scissor-type variable-distance frame suction device, comprising a bracket 1 and two scissor-type suction units (a first scissor-type suction unit 2a and a second scissor-type suction unit 2b) symmetrically arranged on the bracket 1 along the XZ plane. Each scissor-type suction unit comprises a pair of guide rods 21 connected to the bracket 1 along the Y direction, a plurality of suction cup holders 22 passed through by the two guide rods 21, a suction cup assembly 23 fixed to the suction cup holders 22, and a scissor-type mechanism 24 for controlling the equal movement of all suction cup holders 22 along the Y direction. The X and Y directions are both located in the horizontal plane and are perpendicular to each other, and the Z direction is the vertical direction.

[0028] like Figures 2 to 4As shown, the scissors-fork mechanism 24 includes a fixed end 241a, a plurality of X-shaped portions 242 and a movable end 241b connected along the Y direction, the X-shaped portion 242 is formed by a pair of long connecting rods 2421 cross-hinged and the hinge point is connected to the middle of a suction cup fixing seat 22, the fixed end 241a and the movable end 241b both include a pair of short connecting rods 2411, the two short connecting rods 2411 each have one end hinged to each other and the hinge point is connected to the middle of a suction cup fixing seat 22, the end of the long connecting rod 2421 is hinged to the end of the adjacent group of long connecting rods 2421 or the end of the short connecting rod 2411, three hinge points are evenly spaced on the long connecting rod 2421, two hinge points are provided at both ends of the short connecting rod 2411, and the spacing distance between the two hinge points on the short connecting rod 2411 is equal to the distance between two adjacent hinge points on the long connecting rod 2421.

[0029] In the scissor mechanism 24, the distances between all hinge points and adjacent hinge points are fixed values, so a number of diamond structures with the same shape will be formed in the scissor mechanism 24, and the middle parts of adjacent suction cup fixing seats 22 are connected to the same diagonal of the same diamond structure, which is along the Y direction. When the outer end point of the movable end 241b moves along the Y direction, these diamond structures will deform synchronously, thereby achieving equal spacing adjustment of the suction cup fixing seat 22. Two suction cup assemblies 23 are provided on each suction cup fixing seat 22, and the positions of the suction cup assemblies 23 on the first scissor suction unit 2a and the second scissor suction unit 2b correspond to each other, so the corresponding suction cup assemblies 23 can jointly adsorb a frame. This scissor-type frame variable distance suction device can use the scissor mechanism 24 to flexibly adjust the spacing of the suction cup assemblies 23 within a certain length range, thereby meeting the suction requirements of frames of various widths.

[0030] like Figure 5 As shown, the suction cup assembly 23 includes a first suction joint 231, a second suction joint 232, a floating suction block 233, a first suction pipe 234, a second suction pipe 235 and a spring 236. The first suction joint 231 and the second suction joint 232 are fixed on the suction cup fixing seat 22. The first suction pipe 234 and the second suction pipe 235 are both connected to the upper part of the floating suction block 233. The floating suction block 233 has two suction cups that are respectively connected to the first suction pipe 234 and the second suction pipe 235. The first suction pipe 234 is floatingly connected to the first suction joint 231, the second suction pipe 235 is floatingly connected to the second suction joint 232, and a spring 236 is clamped between the first suction pipe 234 and the second suction joint 231.

[0031] The floating suction block 233 relies on two suction cups to absorb the frame, with a dense suction point, making the absorption more stable. The spring 236 allows the floating suction block 233 to have floating space, so that the floating suction block 233 can buffer the pressure when it contacts the frame, preventing the frame from being bent.

[0032] like Figure 1 As shown, pneumatic clamps 3 are provided at the four corners of the bracket 1 , and a pneumatic pressing block 4 is provided on each side of the wide side of the bracket 1 .

[0033] The scissor-type frame variable distance suction device can utilize the pneumatic clamping claw 3 to clamp other objects, and then press them tightly through the pneumatic pressing block 4. In this way, the scissor-type frame variable distance suction device can be used for other purposes.

[0034] like Figure 1 As shown, floating pressure heads 5 are provided at the four corners of the bracket 1 , and the floating pressure blocks 5 are provided on one side of the pneumatic clamping jaws 3 .

[0035] The floating pressure head 5 can buffer the pressure of the scissor-type frame variable distance suction device to prevent the clamped object from being crushed.

[0036] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
