The fixing member 33 is screwed into the through hole from a side surface of the connecting rod 32 facing away from the base plate 11, and is connected to the connecting rod 32. When the relative position of the connecting rod 32 and the bottom plate 11 needs to be fixed, the fixing piece 33 is screwed towards the direction of the lower bottom plate 11, and the fixing piece 33 is abutted with the sliding rail 111 so as to fix the relative position of the connecting rod 32 and the bottom plate 11; when the relative position of the connecting rod 32 and the bottom plate 11 needs to be adjusted, the fixing piece 33 is unscrewed, so that the connecting rod 32 can freely slide on the sliding rail 111.

Specifically, each anti-falling component 3 can be correspondingly provided with a fixing piece 33, so that the structure and the operation steps are simplified, and the cost is reduced.

In the above-mentioned scheme, when the position of the connecting rod 32 needs to be adjusted, the fixing piece 33 can be separated from the sliding rail 111 by rotating the fixing piece 33, so that the connecting rod 32 can freely slide along the sliding rail 111 to change the relative position of the connecting rod 32 and the bottom plate 11; after the relative positions of the connecting rod 32 and the bottom plate 11 are fixed, namely, the position of the anti-falling frame 31 is compatible with the current to-be-clamped piece 10, the fixing piece 33 can be abutted with the sliding rail 111 by screwing the fixing piece 33 so as to fix the relative positions of the connecting rod 32 and the bottom plate 11; the operation is simple and convenient.

Wherein, the two anti-falling assemblies 3 are oppositely arranged at the two side edges or the positions close to the edges of the bottom plate 11 along the second direction X. It will be appreciated that if the fall protection assembly 3 is disposed at a position near the middle of the bottom plate 11, two side edges of the bottom plate 11 along the second direction X may affect the rotation process of the fall protection frame 31, so that the fall protection frame 31 cannot rotate from the second side of the bottom plate 11 to the first side of the bottom plate 11; nor from the first side of the base plate 11 to the second side of the base plate 11.

Above-mentioned scheme, combine fig. 1 and 8, through setting up two anti-falling assemblies 3, can follow to wait to press from both ends of getting a 10 along second direction X and hold respectively and wait to press from both sides and get a 10 to guarantee to press from both sides and get a 10 along second direction X's both ends all atress, even like this clamping jaw subassembly 21 is not hard up can't press from both sides when tightly waiting to press from both sides to get a 10, also accessible two anti-falling assemblies 3's bearing power guarantees to wait to press from both sides and get a 10 not drop, avoid waiting to press from both sides to get a 10 and be damaged or cause the damage to other personnel or devices because of dropping in the transportation. Meanwhile, compared with the anti-falling assembly 3, the probability of falling problem caused by uneven stress of the to-be-clamped piece 10 along the second direction X can be reduced.

In one embodiment, in connection with fig. 4, the clamping mechanism 2 further comprises a drive 24, a first controller 22 and a second controller 23. The driving members 24 are respectively connected with the two clamping jaw assemblies 21; the first controller 22 is electrically connected with the driving piece 24 and controls the driving piece 24 to drive the two clamping jaw assemblies 21 to be close to each other; the second controller 23 is electrically connected to the driving member 24 and controls the driving member 24 to drive the two jaw assemblies 21 away from each other.

Wherein the drive member 24 may be a motor or a pump for driving the jaw assembly 21 in movement. The first controller 22 and the second controller 23 may be MCUs. Approaching each other means that the distance between the two jaw assemblies 21 in the first direction Y gradually decreases. Away from each other means that the distance of the two jaw assemblies 21 in the first direction Y gradually increases.

In the above-mentioned scheme, the relative distance between the two clamping jaw assemblies 21 can be adjusted, so that the clamping jaw assemblies 21 are compatible with the to-be-clamped pieces 10 with different widths.

In one embodiment, the number of the first controllers 22 is at least two, and at least two first controllers 22 are arranged at intervals along any direction parallel to the plane of the bottom plate 11; and/or the number of the second controllers 23 is at least two, and at least two second controllers 23 are arranged at intervals along any direction parallel to the plane of the base plate 11.

The number of the first controllers 22 may be two, and the two first controllers 22 are distributed at intervals along the second direction X; when the workpiece 10 to be clamped needs to be clamped, a user needs to press down one first controller 22 by left and right hands respectively to control the two clamping jaw assemblies 21 to be close to each other; the probability of erroneous operation can be reduced to some extent compared with the case where one first controller 22, i.e., the jaw assembly 21 is controlled to move by one hand. Similarly, the number of the second controllers 23 may be two, and the two second controllers 23 are distributed at intervals along the second direction X; when the distance between the two clamping jaw assemblies 21 needs to be increased, a user needs to press a second controller 23 by left and right hands respectively to control the two clamping jaw assemblies 21 to be away from each other; the probability of erroneous operation can be reduced to some extent compared with the case where one second controller 23, i.e., the jaw assembly 21 is controlled to move by one hand.

In the above-mentioned scheme, the driving member 24 can be driven to operate only when all the first controllers 22 or the second controllers 23 are turned on, for example, when the first controller 22 or the second controller 23 is simultaneously pressed by the left hand and the right hand, so that misoperation can be prevented.

In one embodiment, with reference to fig. 1 and 3, the carrying body 1 further comprises a support assembly 12, the support assembly 12 being provided on the side of the base plate 11 facing away from the jaw assembly 21; one of the support assembly 12 and the fall protection frame 31 includes a ferromagnetic element 122, and the other is provided with a magnet 34, and when the fall protection frame 31 is configured in the second state, the ferromagnetic element 122 and the magnet 34 are magnetically attracted.

Specifically, the supporting component 12 is disposed on the first surface of the base plate 11 and is perpendicular to the plane of the base plate 11. The ferromagnetic element 122 may be a magnet or an element comprising a ferromagnetic material. Metals that can be attracted by magnets, besides iron, also include cobalt, nickel, gadolinium, etc., which are ferromagnetic substances in which many unpaired electrons exist, which create many magnetic domains due to quantum mechanical effects, and which are magnetized when a magnetic field is applied from the outside, thus being attracted by magnets.

According to the scheme, the anti-falling frame 31 is fixed in the second state through magnetic attraction, so that the anti-falling frame 31 can be prevented from being automatically switched from the second state to the first state, and the condition of clamping the to-be-clamped piece 10 is affected.

In one embodiment, as shown in FIG. 1, the support assembly 12 includes a support post 121 and two ferromagnetic elements 122. The support column 121 is arranged on the surface of one side of the bottom plate 11, which is away from the clamping jaw assembly 21; the two ferromagnetic elements 122 are disposed on two sides of the support column 121 along the second direction X; the magnet 34 is arranged at one end of the falling protection frame 31 away from the bottom plate 11.

Wherein the support column 121 may have a rectangular or circular cross section. The support columns 121 may be metal columns. The ferromagnetic element 122 may be welded or fixed to the support post 121 by screws or the like. When the anti-falling frame 31 is configured to the second state, one end of the anti-falling frame 31, which is away from the bottom plate 11, is abutted against the ferromagnetic element 122; one end of the anti-falling frame 31, which is close to the bottom plate 11, is rotatably connected with a connecting rod 32. A portion of the first controller 22 is disposed on one of the ferromagnetic elements 122 and the remaining portion is disposed on the other ferromagnetic element 122. Similarly, a portion of the second controller 23 is disposed on one of the ferromagnetic elements 122, and the remaining portion is disposed on the other ferromagnetic element 122.

By the scheme, the two anti-falling frames 31 can share one supporting column 121, so that the structure is simple, and the cost is low; meanwhile, the magnet 34 is arranged at one end of the anti-falling frame 31, which is away from the bottom plate 11, so that the magnet 34 and the ferromagnetic element 122 are magnetically attracted, and the magnetic attraction between the anti-falling frame 31 and the supporting component 12 is improved.

In one embodiment, referring to fig. 2 and 7, when the fall arrest frame 31 is configured in the second state, the magnet 34 is located on a side surface of the fall arrest frame 31 facing the ferromagnetic member 122.

Wherein, the magnet can be integrally formed with the anti-falling frame 31; or by other fasteners to fall arrest frame 31.

In the above-described configuration, the magnet 34 and the ferromagnetic member 122 can be brought into direct contact and magnetically attracted, and the fall prevention frame 31 can be stably fixed to the support member 12, and the second state can be maintained.

In one embodiment, as shown in FIG. 1, the ferromagnetic element 122 and/or the fall arrest frame 31 are hollow frame structures.

The hollow frame body structure refers to a corresponding structure which is in a frame body shape, such as a rectangular frame or a U-shaped frame; the structure is mainly formed by sequentially connecting and enclosing strip-shaped structures or is directly formed by bending a strip-shaped structure. In combination with fig. 1 and fig. 4, the anti-falling frame 31 may be directly bent into a frame structure with a notch by a strip, and two ends of the strip are provided with circular rings, which are sleeved at the end of the connecting rod 32 and are rotatably connected with the connecting rod 32. The size of the notch of the anti-falling frame 31 along the first direction Y is greater than the size of the bottom plate 11 along the first direction Y, so that the ring of the anti-falling frame 31 can avoid the connection between the bottom plate 11 and the connecting rod 32 and can be freely configured to a first state or a second state. Specifically, the linear distance between the two sides of the anti-falling frame 31 along the first direction Y is greater than the size of the notch of the anti-falling frame 31 along the first direction Y, so as to meet the requirements of the to-be-clamped pieces 10 with different widths as far as possible. Specifically, referring to fig. 1, a minimum linear distance L1 between one end of the anti-falling frame 31 away from the bottom plate 11 and the connecting rod 32 is greater than a maximum linear distance L2 between the connecting rod 32 and the corresponding side edge of the bottom plate 11 along the second direction X; to ensure that the bottom plate 11 does not obstruct the rotation of the drop frame 31.

The ferromagnetic element 122 may be a semi-enclosed frame structure, and two sides of the ferromagnetic element 122 are respectively fixed on the supporting columns 121; a mounting plate is arranged on one side edge of the ferromagnetic element 122 opposite to the support column 121; the first controller 22 and the second controller 23 are provided on the mount, respectively.

In the above scheme, the anti-falling frame 31 with the hollow frame body structure can imitate the peripheral outline of the to-be-clamped piece 10, and is convenient to be sleeved on the periphery of the to-be-clamped piece 10 so as to support the to-be-clamped piece 10 from the bottom of the to-be-clamped piece 10. The ferromagnetic element 122 of the hollow frame structure can simplify the structure, reduce the weight of the product, and facilitate transportation.

In one embodiment, as shown in FIG. 4, jaw assembly 21 includes clamping plate 211 and anti-slip pad 212, with anti-slip pad 212 being provided on a side surface of clamping plate 211 facing the other jaw assembly 21.

The number of the clamping plates 211 may be one or more, and the plurality of clamping plates 211 are sequentially distributed along the second direction X. Preferably, the number of the clamping plates 211 is one, so that the manufacturing is easy, and the condition that two adjacent clamping plates 211 interfere with each other does not occur. Specifically, the clamping plate 211 has a plate shape and extends in the second direction X. The anti-slip pad 212 is used for increasing friction between the clamping jaw assembly 21 and the to-be-clamped workpiece 10, so as to ensure that the to-be-clamped workpiece 10 cannot fall off in the transferring process. The cleat 212 may be a rubber cleat, or a PVC cleat, or TPR cleat, or the like.

By the above scheme, the friction force between the to-be-clamped workpiece 10 and the clamping plate 211 can be improved, and the falling risk of the to-be-clamped workpiece 10 is reduced.

In one embodiment, the anti-slip pad 212 is removably coupled to the clamping plate 211.

Wherein the anti-slip pad 212 and the clamping plate 211 may be connected by a fixing structure such as a bolt, a screw, or the like. By detachably connecting the anti-skid pad 212 with the clamping plate 211, the anti-skid pad 212 can be more slid at regular time, and the anti-skid pad 212 is prevented from being aged and failed.

In one embodiment, the fall arrest frame 31 is further configured to be retractable in its length direction and/or width direction.

The size of the retractable anti-falling frame 31 along the length direction (i.e., the first direction Y) or the width direction is adjustable. Taking the size of the anti-falling frame 31 in the length direction as an example, and defining the side edge of the anti-falling frame 31 along the length direction as a long edge, the long edge of the anti-falling frame 31 can comprise a first rod body and a second rod body, the first rod body and the second rod body are mutually sleeved, and the first rod body and the second rod body can relatively slide along the axial direction of the first rod body so as to adjust the relative distance between the first rod body and the second rod body, thereby changing the length size of the anti-falling frame 31. Of course, the size of the anti-falling frame 31 along the length direction or the width direction can be adjusted, and the connection mode of the umbrella rod of the telescopic umbrella can be similar; or a similar telescopic self-timer stick implementation.

By the above scheme, the anti-falling frame 31 can be adapted to the to-be-clamped pieces 10 with different lengths or widths, and the problem of compatibility of clamping components for clamping the to-be-clamped pieces 10 with different lengths and different widths can be solved in an auxiliary mode.

The specific use of the gripping assembly will be described below using two fall arrest assemblies 3 as an example. As shown in fig. 1, the fixing member 33 is unscrewed, then the position of the connecting rod 32 on the sliding rail 111 is adjusted, and the fixing member 33 is screwed again to fix the position of the connecting rod 32 on the sliding rail 111, so that the position of the anti-falling frame 31 can be compatible with the to-be-clamped member 10. Then, as shown in fig. 2, the two drop frames 31 are retracted upward, and the magnets on the drop frames 31 are automatically attracted to the ferromagnetic elements 122 to be arranged from the first state to the second state and held. Then, as shown in fig. 6, the first controllers 22 on both sides of the support column 121 are pressed simultaneously, and the driving member 24 drives the two clamping plates 211 to move relatively to clamp the member 10 to be clamped. After the clamping member 10 is clamped, the clamping assembly is lifted to a certain height, and then the falling preventing frame 31 is put down as shown in fig. 8, namely, the falling preventing frame 31 is configured from the second state to the first state, and then the movement and the transfer are continued. Before entering the box or before clamping the piece to be clamped from the box, as shown in fig. 6, the anti-falling frame 31 is folded upwards in advance, and the clamping plate 211 only clamps the upper part of the piece to be clamped 10 and cannot interfere with pearl wool wrapping the lower part of the piece to be clamped 10 in the box. Then, the second controllers 23 on both sides of the support column 121 are simultaneously pressed, and the driving member 24 drives the two clamping plates 211 to move oppositely so as to release the member 10 to be clamped.

In this embodiment, there is also provided a gripping device including a gripping assembly and a robotic arm. The clamping component is the clamping component, and the specific structure and the function of the clamping component can be seen from the above. The mechanical arm is connected with the clamping component and is used for driving the clamping component to lift and move. The robot arm may be specifically connected to an end of the support column 121 facing away from the base plate 11.

According to the scheme, the clamping jaw assemblies 21 are located on the same side of the bottom plate 11 and extend towards the same direction, the clamping jaw assemblies 21 can clamp the workpiece 10 to be clamped from two sides of the workpiece 10 to be clamped, so that when the workpiece 10 to be clamped is clamped on a tray or the like or in a box body with the lower part of the workpiece 10 to be clamped wrapped by pearl wool, whether a gap exists at the bottom of the workpiece 10 to be clamped or not, and the placing platform of the workpiece 10 to be clamped is not required, the problem of compatibility of the use scene of the clamping assembly is solved, the workpiece 10 to be clamped, such as the use scene of turning over and entering a box of a battery module, is improved, the degree of automation is improved, time and manpower are saved, and the cost is reduced. Meanwhile, by arranging the anti-falling frame 31, the anti-falling frame 31 can be configured to be in a first state and arranged on the same side with the clamping jaw assembly 21, so that after the to-be-clamped piece 10 is clamped, the anti-falling frame 31 can be wound on the bottom of the to-be-clamped piece 10, the to-be-clamped piece 10 is prevented from falling in the transferring process, and the safe operation is ensured; or the anti-falling frame 31 can be configured to be in the second state so as to be arranged at the opposite side of the clamping jaw assembly 21, so that the anti-falling frame 31 can avoid the clamping path of the clamping jaw assembly 21, and the anti-falling frame 31 is prevented from influencing the process of clamping the clamping jaw assembly 21 to clamp the workpiece 10.
