Description

Technical Field

[0001] The utility model relates to the technical field of transport clamps, in particular to a mattress clamp. Background Art

[0002] Mattresses include spring mattresses and soft mattresses without springs, such as sponge mattresses, silicone mattresses, and polyester fiber mattresses. Conventional mattress clamps typically use two grippers on either side to simultaneously clamp the mattress. This clamping method is somewhat effective for spring mattresses, but when clamping easily deformed or thin mattresses, the center of the mattress bottom tends to sag due to the soft material. Consequently, conventional mattress clamps can easily cause the mattress to fall off during handling, resulting in unreliable clamping. Utility Model Content

[0028] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0029] The embodiment of the present utility model provides a mattress clamp 100.

[0030] As Figure 1 , Figure 2 and Figure 3 shown, the mattress clamp 100 includes a mounting frame 110, a mounting base 120, a plurality of first insertion and clamping modules 130, and at least one second insertion and clamping module 130b;

[0031] A mounting base 120 is provided in the middle of one end face of the mounting frame 110, and the plurality of first insertion and clamping modules 130 and at least one of the second insertion and clamping modules 130b are disposed on the side of the mounting frame 110 facing away from the mounting base 120;

[0032] A plurality of the first clamping modules 130 are close to the edge of the mounting frame 110 and are arranged along the edge of the mattress to be carried;

[0033] At least one of the second clamping modules 130b is arranged away from the edge of the mounting frame 110;

[0034] Both the first clamping module 130 and the second clamping module 130b include: a first air cylinder 131, a first insertion pin 132, a second air cylinder 133 symmetrically arranged with the first air cylinder 131, a second insertion pin 134 symmetrically arranged with the first insertion pin 132, and a fixing plate 135 horizontally arranged relative to the mounting frame 110; the fixing plate 135 is connected to the mounting frame 110; the first air cylinder 131 and the second air cylinder 133 are fixed on one side of the fixing plate 135 close to the mounting frame 110, the piston of the first air cylinder 131 is connected to the first insertion pin 132, and the piston of the second air cylinder 133 is connected to the second insertion pin 134; the moving directions of the first insertion pin 132 and the second insertion pin 134 are arranged at an angle with the fixing plate 135; the first insertion pin 132 and the second insertion pin 134 can penetrate through one side of the fixing plate 135 facing away from the mounting frame 110 and extend out from the fixing plate 135.

[0035] It can be understood that the technical solution of the present utility model is to set a plurality of first clamping modules 130 and at least one second clamping module 130b. Specifically, both the first clamping module 130 and the second clamping module 130b include: a first air cylinder 131, a first insertion pin 132, a second air cylinder 133 symmetrically arranged with the first air cylinder 131, a second insertion pin 134 symmetrically arranged with the first insertion pin 132, and a fixing plate 135 horizontally arranged relative to the mounting frame 110; the fixing plate 135 is connected to the mounting frame 110; the first air cylinder 131 and the second air cylinder 133 are fixed on one side of the fixing plate 135 close to the mounting frame 110, the piston of the first air cylinder 131 is connected to the first insertion pin 132, and the piston of the second air cylinder 133 is connected to the second insertion pin 134; the moving directions of the first insertion pin 132 and the second insertion pin 134 are arranged at an angle with the fixing plate 135; the first insertion pin 132 and the second insertion pin 134 can penetrate through one side of the fixing plate 135 facing away from the mounting frame 110 and extend out from the fixing plate 135. The technical solution of the present utility model inserts the first insertion pin 132 and the second insertion pin 134 into the mattress to be carried respectively. The first insertion pin 132 and the second insertion pin 134 cooperate with each other, and rely on the friction between the first insertion pin 132 and the second insertion pin 134 and the mattress, and rely on the self-weight of the mattress to help the mattress maintain balance in the suspended state, improving the reliability of the mattress clamp 100 for clamping the soft mattress.

[0036] Optionally, the second cylinder 133 is symmetrically arranged with the first cylinder 131, which can be mirror symmetry or central symmetry.

[0037] Optionally, the second pin 134 is symmetrically arranged with the first pin 132, which can be mirror symmetry or central symmetry.

[0038] It should be noted that when the second cylinder 133 and the first cylinder 131 are centrally symmetrically arranged, the first cylinder 131 is arranged close to the second cylinder 133 to reduce the imbalance caused by the self-weight of the mattress and reduce the probability of the mattress accidentally falling from the first pin 132 and the second pin 134.

[0039] It should also be noted that the mounting seat 120 is used to connect the robotic arm, and the mattress is carried under the action of the robotic arm. Optionally, the robotic arm can be a gantry crane or a four-axis handling robotic arm. Those skilled in the art can select different types of robotic arms according to actual needs, so the specific type of the robotic arm is not limited.

[0040] Please continue to refer to Figure 1 and Figure 3 , in a specific embodiment, both the first clamping module 130 and the second clamping module 130b include a connecting rod 138 and an elastic member 139. One end of the connecting rod 138 is connected to the mounting bracket 110, and the other end is connected to the elastic member 139; the fixing plate 135 is mounted on the elastic member 139. It can be understood that the elastic member 139 can generate a shrinking elastic deformation. When the fixing plate 135 contacts the mattress and the first pin 132 and the second pin 134 are inserted into the mattress, the elastic member 139 absorbs a part of the reverse force and reduces the damage probability of the first pin 132 and the second pin 134. Optionally, in order to ensure a certain rigidity and connection reliability, the elastic member 139 is a compression spring made of metal material.

[0041] Please refer to Figure 2 , in a preferred embodiment, the first clamping module 130 further includes a first driving member 136 and a clamping jaw 137. The first driving member 136 is fixed to the fixing plate 135, the clamping jaw 137 is connected to the first driving member 136, and the clamping jaw 137 is located on one side of the fixing plate 135 close to the edge of the mounting bracket 110; the clamping jaw 137 and the surface of the fixing plate 135 facing away from the mounting bracket 110 cooperate with each other to grasp the edge of the mattress.

[0042] It can be understood that the jaw 137 and the side of the fixed plate 135 facing away from the mounting frame 110 cooperate with each other to grip the edge of the mattress, which can improve the stability of the mattress clamp 100 and prevent the mattress from accidentally falling.

[0043] Further, as Figure 1 shown, the mattress clamp 100 further includes a plurality of first linear modules 140 connected to the mounting frame 110; the first linear modules 140 are used to drive the first plug-in clamping modules 130 to move away from the center of the mounting frame 110 respectively.

[0044] It can be understood that after the jaw 137 and the side of the fixed plate 135 facing away from the mounting frame 110 cooperate to grip the edge of the mattress, the first linear motor modules drive different first plug-in clamping modules 130 to move away from the center of the mounting frame 110 respectively, which can straighten the mattress and improve the reliability of the first pin 132 and the second pin 134 to pick up the mattress in the above solution.

[0045] Optionally, as Figure 2 shown, in order to increase the friction when the jaw 137 clamps the edge of the mattress, the jaw 137 is provided with a protrusion 1371, and the protrusion 1371 contacts the mattress for clamping and fixing the mattress.

[0046] Further, as Figure 1 and Figure 4 shown, the mattress clamp 100 further includes a second linear module 150; the second linear module 150 is connected to the mounting frame 110, and part of the first linear modules 140 are connected to the mounting frame 110 through the second linear module 150, and the second linear module 150 drives the first plug-in clamping modules 130 to move in a direction perpendicular to the movement direction of the first linear modules 140 through the first linear modules 140.

[0047] It can be understood that the setting of the first linear modules 140 is mainly to make the first plug-in clamping modules 130 move away from or close to the center of the mounting frame 110. By setting the second linear module 150, the second linear module 150 drives part of the first linear modules 140 to drive the first plug-in clamping modules 130 to move in a direction perpendicular to the movement direction of the first linear modules 140. So that the first plug-in module can move along the first linear module 140 and can also move along the second linear module 150. Thus, part of the first plug-in modules can not only straighten the mattress but also adapt to mattresses of different sizes. It can also be understood that the setting of the second linear module 150 is mainly to adapt to different mattress sizes.

[0048] Specifically, after the above-mentioned mattress clamp 100 transports a 1.8-meter-wide mattress, it needs to be converted to transport a 1.5-meter-wide mattress. The second linear module 150 operates to drive part of the first linear module 140 to adjust the position along the width direction of the 1.5-meter-wide mattress towards the center of the mattress width. Thereby improving the applicability of the mattress clamp 100.

[0049] Optionally, the first linear module 140 and the second linear module 150 are magnetic induction linear modules, and can also be screw motor linear modules.

[0050] In one embodiment, to better conform to the application scenario, the first linear module 140 is a screw motor linear module.

[0051] It can be understood that the screw motor linear module is mainly composed of components such as a driving motor, reduction gears, a screw, a nut, a guide sleeve, a push rod, a sliding seat, a spring, a housing, a turbine, and a micro motion control switch. And the screw motor linear module has the advantages of high automation and precise control. The screw motor linear module is a well-known technology to those skilled in the art, so the specific connection method thereof will not be explained one by one.

[0052] Optionally, the first driving member 136 can be a servo motor or a rotary cylinder.

[0053] In one embodiment, the first driving member 136 is a rotary cylinder. It can be understood that the first driving member 136 is mainly used to drive the jaw 137 to rotate within a certain range, and it usually has two working positions. Therefore, the rotary cylinder is relatively simple to control compared with the servo motor and the cost is also lower.

[0054] As Figure 2 shown, in a specific embodiment, the included angle between the first pin 132 and the fixed plate 135 is α, where 20° ≤ α ≤ 60°. It can be understood that if the included angle α is too large, the grasping ability will be insufficient, resulting in the mattress being easily accidentally dropped; if the included angle α is too small, the first pin 132 or the second pin 134 may not be effectively inserted into the mattress. Optionally, the included angle α can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°.

[0055] The above is the case. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
