[0076] The single-powered multi-point workpiece clamping carrier 1000 of the present invention will now be described in detail with reference to the accompanying drawings.

[0077] Reference Figures 1 to 6 As shown, the single-power multi-point workpiece clamping carrier 1000 provided according to an embodiment of the present invention includes a base plate 10, a workpiece carrier plate 20, a left and right moving component 30 and a plurality of elastic clamps 40 for clamping workpieces.

[0078] The workpiece carrier plates 20 are stacked and fixed on the base plate 10. Multiple slots 201 extending vertically to the bottom surface of the workpiece carrier plate 20 are formed on its upper surface. Multiple sliding cavities 202, corresponding to and communicating with the slots 201, are formed on the right side of the slots 201 in a left-right direction on the bottom surface of the workpiece carrier plate 201. Specifically, referring to… Figure 5 and Figure 6 As shown;

[0079] Furthermore, in comparison Figure 3 and Figure 4 As shown, the upper surface of the base plate 10 has a sliding groove 101 extending downward in the left-right direction; the left-right moving member 30 is movable left-right and locked in the sliding groove 101; multiple elastic clips 40 are fixed on the left-right moving member 30 and are correspondingly limited in multiple sliding cavities 202.

[0080] The multiple slots 201 may be the same or different in size to accommodate workpieces of appropriate size; when the multiple elastic clips 40 are moved to the left by the left and right moving member 30 and move a certain distance along the multiple sliding cavities 202, the multiple elastic clips 40 can elastically abut against the workpiece inserted in the multiple slots 201.

[0081] Based on the above, it is clear that in specific implementation, this application is mainly used as a single-power multi-point workpiece clamping carrier 1000 that can clamp and transport workpieces of the same or different sizes.

[0082] Specifically, in the application, the plurality of elastic clamps 40 are driven by the left-right moving member 30 to move rightward along the plurality of sliding cavities 202, then the lower parts of the workpieces of the same or different sizes are inserted into the plurality of insertion slots 201 corresponding to their sizes, then the plurality of elastic clamps 40 are driven by the left-right moving member 30 to move leftward by a certain distance, and the plurality of elastic clamps 40 can elastically abut against the right side surfaces of the lower parts of the workpieces inserted into the plurality of insertion slots 201. Thus, the plurality of inserted workpieces are clamped and fixed by the application, and finally the application can be transferred to the side of the required automatic equipment by a material conveying belt, and the plurality of clamped workpieces can be picked up by a required mechanical hand and fixed to a product body.

[0083] For the above, it can be clear that:

[0084] Firstly, the plurality of elastic clamps 40 can clamp the workpieces to be transferred by only one left-right moving member 30, which greatly reduces the cost of the application compared with the background art, and effectively saves raw materials.

[0085] Secondly, the application only needs one left-right moving member 30, which also greatly reduces the maintenance cost of the application compared with the background art.

[0086] Thirdly, the plurality of elastic clamps 40 elastically abut against the right side surfaces of the lower parts of the workpieces inserted into the plurality of insertion slots 201, so that they can independently generate a certain elastic pressure to clamp the workpieces in the left-right direction according to the sizes of the workpieces, which not only makes the clamped workpieces not easy to be clamped and damaged, but also makes the clamping force of the workpieces flexible.

[0087] Further, the above optimization design makes the application as a whole adopt a single-power multi-point elastic clamping mode to clamp the plurality of workpieces of the same or different sizes, which greatly reduces the production cost and maintenance cost of the application as a whole, and also makes the application not easy to clamp and damage the workpieces. Therefore, the application as a whole has strong practicability and good use effect.

[0088] Further, in specific implementation, it is still shown in Figure 3 and Figure 4 According to one embodiment of the application, the left-right moving member 30 includes a sliding plate 301 arranged in the left-right direction and a plurality of branch plates 302 vertically connected to the front and rear sides of the sliding plate 301 and in the same plane as the sliding plate 301.

[0089] The sliding plate 301 is clamped in the sliding groove 101 and can move left and right. The bottom support plate 10 has a plurality of accommodation grooves 102 on the upper end surface and on both sides of the sliding groove 101, which can accommodate a plurality of branch plates 302. The left and right widths of the accommodation grooves 102 are greater than the left and right widths of the branch plates 302. The branch plates 302 can move forward and backward along the accommodation grooves 102.

[0090] Therefore, it can be understood that when the left and right moving member 30 is divided into the sliding plate 301 and a plurality of branch plates 302, and the sliding plate 301 is clamped in the sliding groove 101 and can move left and right, and the branch plates 302 can move forward and backward along the accommodation grooves 102, the overall material usage is reduced, and the left and right movement is more stable and reliable.

[0091] Further, in specific implementation, continue to refer to Figure 3 and Figure 4 According to one embodiment of the application, the left and right moving member 30 further comprises a plurality of reset springs 303.

[0092] The plurality of reset springs 303 are arranged in the left and right directions, and the left and right ends thereof correspond to the right side surface of the branch plates 302 and the right inner wall of the accommodation grooves 102.

[0093] Initially, the plurality of elastic clamps 40 correspond to the lower side of the plurality of insertion grooves 201 to correspond to the blocking of the plurality of insertion grooves 201, and initially, the plurality of reset springs 303 are in a natural state.

[0094] Therefore, it can be clearly understood that in the application of the application, the left and right moving member 30 drives the plurality of elastic clamps 40 to move right along the plurality of sliding cavities 202, at this time, the plurality of elastic clamps 40 correspond to the right side of the plurality of insertion grooves 201, then, a plurality of workpieces of the same or different sizes are inserted into the plurality of insertion grooves 201, and subsequently, the left and right moving member 30 is loosened, and the plurality of reset springs 303 are elastically reset to reversely push the left moving member 30, at this time, the left and right moving member 30 drives the plurality of elastic clamps 40 to move left by a certain distance, and the plurality of elastic clamps 40 correspond to the elastic clamping of the right side surface of the lower part of the workpiece inserted in the plurality of insertion grooves 201. In this way, the plurality of inserted workpieces are clamped and fixed by using the application.

[0095] And, the application provides counter-thrust by arranging a plurality of reset springs 303, so that the left and right moving member 30 does not need to be driven by power during use, especially when moving left, so that the use cost is lower.

[0096] Preferably, in specific implementation, according to one embodiment of the application, the right side of each of the plurality of branch plates 302 is provided with a fixing groove A3021 opened to the left; and the right inner wall of each of the plurality of accommodating grooves 102 is provided with a fixing groove B1021 opened to the right.

[0097] Preferably, in specific implementation, according to one embodiment of the application, the right side of each of the plurality of branch plates 302 is provided with a fixing groove A3021 opened to the left; and the right inner wall of each of the plurality of accommodating grooves 102 is provided with a fixing groove B1021 opened to the right.

[0098] Preferably, in specific implementation, according to one embodiment of the application, the right side of each of the plurality of branch plates 302 is provided with a fixing groove A3021 opened to the left; and the right inner wall of each of the plurality of accommodating grooves 102 is provided with a fixing groove B1021 opened to the right.

[0099] Further, in specific implementation, according to one embodiment of the application, the left and right moving member 30 further comprises a pushing device (not shown).

[0100] Preferably, in specific implementation, according to one embodiment of the application, the left side of the bottom support plate 10 is provided with a through opening 103 communicating with the sliding groove 101; and the pushing device (not shown) is installed on the left side of the bottom support plate 10 and / or the left side of the workpiece carrier plate 20, and extends into the sliding groove 101 from the through opening 103 to be fixedly connected with the left end of the sliding plate 301, so as to drive the sliding plate 301 to move left and right along the sliding groove 101.

[0101] Preferably, the pushing device (not shown) of the application adopts a pushing cylinder, so that when in use, the pushing device (not shown) is pushed right by air, and is pushed left by the plurality of reset springs 303 providing leftward thrust, so that the use cost of the pushing device (not shown) of the application is also very low when adopting a pushing cylinder.

[0102] In addition, in specific implementation, according to one embodiment of the application, the application further comprises a fixed sliding rail 50 and a guide block 60.

[0103] Preferably, in specific implementation, according to one embodiment of the application, the left side of the bottom support plate 10 is provided with a through opening 103 communicating with the sliding groove 101; and the pushing device (not shown) is installed on the left side of the bottom support plate 10 and / or the left side of the workpiece carrier plate 20, and extends into the sliding groove 101 from the through opening 103 to be fixedly connected with the left end of the sliding plate 301, so as to drive the sliding plate 301 to move left and right along the sliding groove 101.

[0104] Therefore, the left and right moving member 30 can be guided in the left and right directions by the fixed slide rail 50 and the guide block 60 arranged on the fixed slide rail 50, so that the left and right movement is more stable and reliable.

[0105] In addition, according to an embodiment of the present application, each of the elastic clamps 40 comprises a clamping block 401 and an elastic block 402.

[0106] The clamping blocks 401 are arranged in the vertical direction, and the upper ends of the clamping blocks 401 are correspondingly limited in the sliding cavities 202. The elastic blocks 402 are correspondingly connected to the bottoms of the clamping blocks 401.

[0107] In addition, the left side of each of the branch plates 302 is provided with a movable slot A3022. The elastic blocks 402 are fitted in the movable slots A3022 and can move left and right.

[0108] Therefore, the clamping blocks 401 of the elastic clamps 40 can provide elastic force to the workpieces correspondingly inserted into the insertion slots 201, so that the workpieces are not clamped rigidly.

[0109] In addition, the movable slots A3022 are arranged on the left side of each of the branch plates 302, and the elastic blocks 402 are fitted in the movable slots A3022 and can move left and right. The main purpose is that the elastic blocks 402 are limited in the circumferential direction, so that they can only move left and right, so that the stability of movement can be better maintained. In addition, the elastic blocks 402 are not arranged on the upper surface of the branch plates 302, so that the thickness of the branch plates 302 can be effectively reduced, and the height of the elastic clamps 40 can be reduced, so that the overall structure can be thin, the weight of the application can be greatly reduced, and the raw materials can be saved.

[0110] It should be noted that, in specific implementation, according to an embodiment of the present application, each of the elastic clamps 40 further comprises a locking rod 403.

[0111] The right side of each of the elastic blocks 402 is provided with a pressing slot 4021, and a pressing spring 4022 is arranged in the pressing slot 4021 and can move left and right. The upper end of the pressing spring 4022 is provided with a movable slot B4023, and the width of the movable slot B4023 is greater than the outer diameter of the locking rod 403.

[0112] And, the upper end face of the plurality of branch plates 302 is respectively provided with a plurality of insertion holes 3023 corresponding to the plurality of movable grooves A3022; a plurality of locking rods 403 are inserted into the plurality of insertion holes 3023, and the lower ends of the plurality of locking rods 403 pass through the plurality of movable grooves B4023 and extend into the plurality of elastic grooves 4021; the right end of the top pressing spring 4022 installed in the elastic groove 4021 of each elastic block 402 corresponds to the left wall of the locking rod 403 at the corresponding position; and the plurality of movable grooves A3022 pass through the right side of the plurality of branch plates 302.

[0113] Initially, the plurality of top pressing springs 4022 are in a natural state or a compressed state, so that the right wall of the lower end of the plurality of locking rods 403 corresponds to the right inner wall of the plurality of movable grooves B4023.

[0114] From the above, it can be summarized that:

[0115] On the one hand, each elastic clamp 40 including the locking rod 403, in actual use, based on the plurality of elastic blocks 402 being clamped in the plurality of movable grooves A3022 in a left-right movable interference fit, since the right end of the top pressing spring 4022 installed in the elastic groove 4021 of each elastic block 402 corresponds to the left wall of the locking rod 403 at the corresponding position, the top pressing spring 4022 is also good in clamping stability and is not easy to move circumferentially, so that each elastic clamp 40 is very stable in use, and has a long service life.

[0116] On the other hand, when the plurality of locking rods 403 are inserted into the plurality of insertion holes 3023, and the lower ends of the plurality of locking rods 403 pass through the plurality of movable grooves B4023 and extend into the plurality of elastic grooves 4021, the plurality of elastic clamps 40 of the present application are fixed well and are not easy to fall off, and when the left-right width of the plurality of movable grooves B4023 is limited, the left-right stroke of the plurality of clamping blocks 401 is limited, so that the left-right stroke of the plurality of clamping blocks 401 can be well controlled when the plurality of clamping blocks 401 move left and right, so that the workpiece is not easy to be clamped and damaged due to excessive left stroke.

[0117] In addition, when a certain top pressing spring 4022 needs to be replaced due to reduced elasticity after long-term use, the locking rod 403 is directly taken out from the corresponding position of the insertion hole 3023, and at this time, the top pressing spring 4022 to be replaced is taken out from the corresponding position of the elastic groove 4021, so that the plurality of elastic clamps 40 of the present application are convenient to disassemble and maintain.

[0118] Therefore, the overall use effect of the present application can be effectively improved.

[0119] It should be further supplemented that, in specific implementation, according to one embodiment of the present application, the workpiece carrier plate 20 is internally provided with a negative pressure suction channel 203 connected to an external negative pressure suction device, and the upper end surface of the workpiece carrier plate 20 is internally provided with at least one negative pressure suction hole 204 corresponding to the negative pressure suction channel 203 and used for negative pressure adsorption of the workpiece beside each of the plurality of insertion slots 201.

[0120] As can be clearly seen from the above, in specific implementation, due to the provision of the negative pressure suction channel 203 and the plurality of negative pressure suction holes 204, on the basis of the use of the plurality of elastic clamps 40 of the present application to correspondingly clamp a plurality of workpieces of the same or different sizes, the present application further provides a negative pressure suction force through an external negative pressure suction device to drive the plurality of negative pressure suction holes 204 to correspondingly negative pressure adsorb the workpiece, so that the workpiece to be clamped and transported is more fixed and stable, is less likely to shake during transportation, and can be better kept in the initial clamped state, so that the subsequent mechanical hand used can more stably pick it up in a suitable orientation and angle.

[0121] Furthermore, the above optimization design enables the overall use effect of the present application to be optimal.
