Description

Technical Field

[0001] The invention relates to the technical field of manipulators, and in particular to a battery clamp. Background Art

[0002] During the transportation of batteries in the production process, the clamping claws of the batteries generally use servo motors or cylinders as power sources, and are equipped with plate-like structure clamps on both side walls of the battery to clamp the battery. However, the friction between the plate-like structure clamps and the battery is relatively small, and it is easy for the clamps to loosen during the transportation of the battery, causing the battery to fall and be damaged. Summary of the invention

[0003] In view of the above-mentioned technical deficiencies, the technical problem to be solved by the present invention is to provide a battery clamp that can protect the battery when clamping.

[0004] In order to solve the above technical problems, the present invention provides a battery clamp, comprising:

[0005] Fixed seat;

[0006] A driving cylinder, wherein two driving cylinders are provided, and the two driving cylinders are symmetrically arranged on a fixed seat, and both driving cylinders are driven by a lead screw and nut assembly and move horizontally on the fixed seat;

[0007] A clamping jaw seat, the clamping jaw seat is vertically arranged on the piston rod of the driving cylinder, and an opening groove is arranged at one end of the clamping jaw seat away from the driving cylinder;

[0008] An anti-skid bottom drag component, the anti-skid bottom drag component is movably arranged in the open groove;

[0009] A flip bottom bracket assembly, wherein two flip bottom bracket assemblies are provided, and the two flip bottom bracket assemblies are movably arranged on two opposite side walls of the clamping claw seat;

[0010] Among them, the anti-skid bottom drag component includes a driving motor 1 and a driving motor 2 which are embedded in the inner wall of the opening groove from top to bottom in sequence. A rotating roller is coaxially arranged on the output shaft of the driving motor 1, and an arc-shaped extrusion plate is arranged on the outer peripheral wall of the rotating roller. A rotating rod is coaxially arranged on the output shaft of the driving motor 2. The rotating roller and the rotating rod are movably arranged in the opening groove in sequence from top to bottom, an L-shaped bottom support plate is arranged on the outer peripheral wall of the rotating rod, a forward and reverse switch is electrically connected to the driving motor 2, and a switch trigger device is arranged in the opening side wall of the opening groove, and the switch trigger device is in contact with the forward and reverse switch.

[0011] Preferably, the flip base assembly comprises:

[0012] A mounting plate, the mounting plate being connected to the side wall of the clamping jaw seat through a plurality of connecting bolts;

[0013] A flip side plate, wherein a plurality of flip side plates are arranged horizontally and in parallel in sequence, the flip side plate close to the side wall end of the clamping claw seat is arranged on the mounting plate, and two adjacent flip side plates are hingedly connected by a rotating shaft with a torsion spring;

[0014] A bottom bracket groove, which is arranged at the bottom of the flip side plate;

[0015] A spring rod, the spring rod being vertically arranged in the bottom bracket slot;

[0016] A bottom bracket seat, the bottom bracket seat is horizontally connected to the spring rod, and the bottom bracket seat is slidably arranged in the bottom bracket slot;

[0017] The bottom bracket is movably embedded in the side wall of the bottom bracket seat through a telescopic spring. When two side walls of the battery are clamped by two clamping claw seats, it is convenient to extend to the bottom of the battery through the bottom bracket to prevent the battery from loosening and falling off during the clamping process.

[0018] Preferably, the switch triggering device comprises:

[0019] A switch slot, which is embedded in the open end of the opening slot;

[0020] A trigger rod, the trigger rod is movably arranged in the switch slot;

[0021] A trigger pressing block, which is arranged at one end of the trigger rod located in the switch slot, and one end of the trigger rod away from the trigger pressing block penetrates to the outside of the clamping claw seat;

[0022] A return spring, the return spring is sleeved on the outside of the trigger rod, and the two ends of the return spring are respectively fixedly connected to the bottom surface of the switch slot and the trigger pressing block;

[0023] The forward and reverse switch is embedded on the inner wall of the switch slot, and the trigger pressing block contacts the forward and reverse switch, so that the forward and reverse switch can be controlled by squeezing the trigger rod before and after clamping the battery, so that the flipping position of the L-shaped bottom support plate in the open slot can be controlled by driving motor 2.

[0024] Preferably, the two opposite side walls of the two clamping jaw seats are also provided with anti-skid card components, and the anti-skid card components include:

[0025] There are two mounting grooves, and the two mounting grooves are arranged in parallel and spaced apart on the side wall of the clamping jaw seat, the opening of the mounting groove is located on the side wall of the clamping jaw seat, and the opening groove is located between the two mounting grooves;

[0026] Anti-skid card blocks, a plurality of which are provided, and the anti-skid card blocks are movably arranged in the installation groove;

[0027] The convex block is arranged on the side wall of the anti-skid card block near the opening of the installation groove. When two side walls of the battery are clamped by the positions of the anti-skid card components on the two clamping claw seats, the convex blocks at the corresponding positions of the bottom of the battery can automatically support the battery according to the different clamping positions of the battery to prevent the battery from sliding down.

[0028] Preferably, the anti-slip blocks are spaced apart in sequence from top to bottom in the mounting groove, and the anti-slip blocks are movably connected in the mounting groove through multiple compression springs. When two side walls of the battery are clamped by the positions of the anti-slip card assemblies on the two clamping claw seats, the anti-slip blocks at the corresponding positions on the bottom of the battery can pop out of the mounting groove under the action of the compression springs, and then the battery can be supported through the protrusions.

[0029] Preferably, the side wall of the flip side plate close to the bottom bracket is on the same vertical plane as the opening of the mounting slot, so that the flip side plate can be in close contact with the side wall of the battery when the battery is clamped.

[0030] Preferably, the height of the vertical end of the L-shaped bottom support plate is greater than the distance from the outer wall of the rotating rod to the bottom surface of the clamping claw seat, so that when the clamping claw seat clamps and lifts the battery, the L-shaped bottom support plate can be flipped out of the opening groove, thereby facilitating the protection of the bottom of the battery through the horizontal end of the L-shaped bottom support plate to prevent the battery from slipping between the clamping claw seats.

[0031] Preferably, the length direction of the arc extrusion plate is consistent with the length direction of the axis of the rotating roller, so that the arc extrusion plate can be driven to rotate when the rotating roller rotates, so that the side wall of the battery can be squeezed by the arc extrusion plate, which is conducive to firmly clamping the battery between the clamping claw seats.

[0032] The beneficial effects of the present invention are as follows: 1. The anti-slip bottom drag assembly provided in the present invention enables the L-shaped bottom support plate to flip over through a switch trigger device when the clamping claw seat clamps the battery, thereby providing protective support for the bottom of the clamped battery and preventing the battery from falling off between the clamping claw seats.

[0033] 2. After the battery is clamped by the clamping jaw seat, the driving motor can be started to drive the rotating roller to rotate, so that the arc-shaped extrusion plate rotates toward the direction close to the battery until the arc-shaped extrusion plate contacts the outside of the battery, thereby preventing the battery from slipping between the clamping jaw seats.

[0034] 3. When the battery is clamped in the position of the anti-slip card assembly, the anti-slip blocks near the top and bottom of the battery can pop out from the installation slot under the action of the compression spring. At this time, the protrusions can be located at the top and bottom of the battery, thereby improving the limiting and supporting effect on the battery and preventing the battery from falling.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1

[0047] like Figures 1 to 4 , Figure 8 As shown, the present invention provides a battery clamp, comprising a fixing seat 1; two driving cylinders 2 are provided, the two driving cylinders 2 are symmetrically arranged on the fixing seat 1, and the two driving cylinders 2 are driven by a screw nut assembly and move horizontally on the fixing seat 1; a clamping claw seat 3 is vertically arranged on the piston rod of the driving cylinder 2, and an opening groove 31 is arranged at one end of the clamping claw seat 3 away from the driving cylinder 2; an anti-skid bottom drag assembly 4 is movably arranged in the opening groove 31; two flip bottom bracket assemblies 5 are provided, and the two flip bottom bracket assemblies 5 are movably arranged on two opposite side walls of the clamping claw seat 3 respectively;

[0048] The anti-skid bottom drag assembly 4 includes a driving motor 1 41 and a driving motor 2 42 which are sequentially embedded in the inner wall of the opening groove 31 from top to bottom. A rotating roller 411 is coaxially arranged on the output shaft of the driving motor 1 41, and an arc-shaped extrusion plate 412 is arranged on the outer peripheral wall of the rotating roller 411. A rotating rod 421 is coaxially arranged on the output shaft of the driving motor 2 42. The rotating roller 411 and the rotating rod 421 are movably arranged in the opening groove 31 from top to bottom in sequence. An L-shaped bottom supporting plate 422 is arranged on the outer peripheral wall of the rotating rod 421. A forward and reverse switch 4235 is electrically connected to the driving motor 2 42. A switch trigger device 423 is arranged in the opening side wall of the opening groove 31, and the switch trigger device 423 is in contact with the forward and reverse switch 4235; the height of the vertical end of the L-shaped bottom supporting plate 422 is greater than the distance from the outer peripheral wall of the rotating rod 421 to the bottom surface of the clamping claw seat 3; the length direction of the arc-shaped extrusion plate 412 is consistent with the length direction of the axis of the rotating roller 411;

[0049] The switch trigger device 423 includes a switch slot 4231, which is embedded in the open end of the opening slot 31; the trigger rod 4232 is movably arranged in the switch slot 4231; the trigger pressing block 4233 is arranged at one end of the trigger rod 4232 located in the switch slot 4231, and the end of the trigger rod 4232 away from the trigger pressing block 4233 passes through the outside of the clamping claw seat 3; the return spring 4234 is sleeved on the outside of the trigger rod 4232, and the two ends of the return spring 4234 are respectively fixedly connected to the bottom surface of the switch slot 4231 and the trigger pressing block 4233; the forward and reverse switch 4235 is embedded on the inner wall of the switch slot 4231, and the trigger pressing block 4233 is in contact with the forward and reverse switch 4235.

[0050] First, according to the outer dimensions of the battery, the two driving cylinders 2 are driven by the screw and nut assembly to move horizontally on the fixed seat 1 to adjust the spacing (two sets of screw and nut assemblies can be provided to drive the two driving cylinders 2 respectively to achieve movement. The screw and nut assembly is a prior art, so it is not described here), and then the position of the clamping claw seat 3 in the height direction is adjusted by the driving cylinder 2 so that the battery is located between the two clamping claw seats 3; then the two driving cylinders 2 and the clamping claw seat 3 are driven by the screw and nut assembly to move simultaneously in the direction close to the battery, so that the battery can be clamped by the two clamping claw seats 3.

[0051] Before clamping the battery, after the battery is clamped by the two clamping claw seats 3, the bottom surface of the clamping claw seats 3 and the placement surface of the battery are in conflict with each other, which can squeeze the trigger rod 4232, so that the trigger rod 4232 moves into the switch slot 4231 and conflicts with the forward and reverse switch 4235 (the forward and reverse switch 4235 has three contacts inside: a common contact, a forward transfer contact and a reverse contact), that is, the trigger pressing block 4233 on the trigger rod 4232 conflicts with the forward transfer contact on the forward and reverse switch 4235. At this time, the driving motor 2 42 can be started to drive the rotating rod 421 and the L-shaped bottom support plate 422 to rotate, so that the horizontal end of the L-shaped bottom support plate 422 flips in the direction away from the battery, that is, the L-shaped bottom support plate 422 will not conflict with the placement surface of the battery; when Start the driving cylinder 2 to drive the clamping jaw seat 3 to move in the vertical direction away from the placement surface of the battery. After the bottom surface of the clamping jaw seat 3 is separated from the placement surface of the battery, the trigger rod 4232 moves to the outside of the switch slot 4231 under the action of the return spring 4234. At the same time, the trigger pressing block 4233 on the trigger rod 4232 conflicts with the reversing contact on the forward and reverse switch 4235. At this time, the driving motor 2 42 can be started to drive the rotating rod 421 and the L-shaped bottom support plate 422 to rotate, so that the horizontal end of the L-shaped bottom support plate 422 flips toward the direction close to the bottom surface of the battery until the horizontal end of the L-shaped bottom support plate 422 contacts the bottom surface of the battery, so that the battery can be protected by the horizontal end of the L-shaped bottom support plate 422 to prevent the battery from slipping between the clamping jaw seat 3.

[0052] After the battery is clamped by the clamping claw seat 3, the driving motor 41 can be started to drive the rotating roller 411, so that the arc extrusion plate 412 rotates toward the direction close to the battery (the rotation direction of the arc extrusion plate 412 is from the bottom direction of the battery toward the top direction of the battery) until the arc extrusion plate 412 conflicts with the outside of the battery, thereby preventing the battery from slipping between the clamping claw seat 3; the arc extrusion plate 412 can be made of rubber material, which is beneficial to increase the friction between the outer wall of the battery and will not cause scratches on the outer wall of the battery.

[0053] Embodiment 2

[0054] Based on the first embodiment, Figure 1 and Figure 5 As shown, the flip base support assembly 5 includes a mounting plate 51, which is connected to the side wall of the clamping jaw seat 3 by a plurality of connecting bolts; a plurality of flip side plates 52 are horizontally arranged in parallel in sequence, and the flip side plate 52 close to the side wall end of the clamping jaw seat 3 is arranged on the mounting plate 51, and two adjacent flip side plates 52 are hinged by a rotating shaft 53 with a torsion spring; a base support groove 54 is arranged at the bottom of the flip side plate 52; a spring rod 55 is vertically arranged in the base support groove 54; a base support seat 56 is horizontally connected to the spring rod 55, and the base support seat 56 is slidably arranged in the base support groove 54; a base support 57 is movably embedded in the side wall of the base support seat 56 through a telescopic spring.

[0055] After two side walls of the battery are clamped by the two clamping claw seats 3 (when the two clamping claw seats 3 move toward the battery for clamping, the bottom surfaces of the two clamping claw seats 3 first conflict with the placement surface of the battery, and at the same time the placement surface of the battery presses the bottom bracket seat 56, so that the bottom bracket seat 56 squeezes the spring rod 55 and retracts it into the bottom bracket slot 54; when the two clamping claw seats 3 gradually approach the battery for clamping, the bottom bracket 57 gradually conflicts with the side wall of the battery, thereby compressing the telescopic spring, so that the bottom bracket 57 retracts into the side wall of the bottom bracket seat 56), and when the size of the battery is large, flip it over. The side walls of the side plate 52 close to the bottom bracket groove 54 can rotate around the rotating shaft 53 with the torsion spring, and are in contact with the other two side walls of the battery; the bottom of the bottom bracket seat 56 pops out to the outside of the bottom bracket groove 54 under the action of the spring rod 55 (at this time, at least half of the height of the bottom bracket seat 56 is still located in the bottom bracket groove 54), and the bottom bracket 57 in the side wall of the bottom bracket seat 56 can be located at the outer side of the bottom surface of the battery. Under the action of the telescopic spring, the bottom bracket 57 pops out from the side wall of the bottom bracket seat 56 to below the bottom surface of the battery, thereby preventing the battery from suddenly loosening and falling during the clamping process.

[0056] Embodiment 3

[0057] Based on the first embodiment, Figure 1 , Figures 5 to 7 As shown, anti-skid card assemblies 6 are also provided on the opposite side walls of the two clamping jaw seats 3, and the anti-skid card assemblies 6 include mounting grooves 61, two mounting grooves 61 are provided, and the two mounting grooves 61 are arranged in parallel and spaced on the side walls of the clamping jaw seat 3, the opening of the mounting groove 61 is located on the side wall of the clamping jaw seat 3, and the opening groove 31 is located between the two mounting grooves 61; a plurality of anti-skid card blocks 62 are provided, and the anti-skid card blocks 62 are movably arranged in the mounting groove 61; the protrusions 63 are arranged on the side walls of the anti-skid card blocks 62 close to the openings of the mounting grooves 61; the anti-skid card blocks 62 are spaced in sequence from top to bottom in the mounting groove 61, and the anti-skid card blocks 62 are movably connected in the mounting groove 61 through a plurality of compression springs 621.

[0058] When the anti-skid card assembly 6 on the two clamping claw seats 3 is positioned to clamp two side walls of the battery (at this time, the bottom of the battery is not on the same plane as the bottom surface of the clamping claw seat 3, and the bottom of the battery corresponds to the position of the mounting groove 61), the anti-skid card block 62 close to the top and bottom of the battery can pop out from the mounting groove 61 under the action of the compression spring 621. At this time, the protrusion 63 can be located at the top and bottom of the battery, thereby limiting and supporting the battery to prevent the battery from moving; at the same time, the anti-skid card block 62 located at the side wall of the battery can compress the compression spring 621 under the squeezing of the side wall of the battery and enter the mounting groove 61.

[0059] The side wall of the flip side plate 52 close to the base 57 and the opening of the mounting groove 61 are on the same vertical plane, so that when the clamping claw seat 3 is used to clamp the battery, the side walls of each flip side plate 52 close to the base 57 and the side walls of the clamping claw seat 3 can be in close contact with the side walls of the battery.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
