[0046] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0047] The following disclosure provides a number of different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are merely examples and the purpose is not to limit the present application. In addition, reference numerals and / or letters can be repeated in different examples of the present application. Such repetition is for the purpose of simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0048] For ease of description, spatial relative terms can be used herein to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" other elements or features will be oriented as "above" or "above" other elements or features. Therefore, the example term "below" can include both upward and downward positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are interpreted accordingly.

[0049] The traditional variable distance mechanism is a cam slot mechanism, a scissor fork linkage mechanism, etc., in order to provide stable clamping force, an additional clamping driving mechanism needs to be additionally provided, when the number of battery cells is large, these mechanisms not only have relatively high cost, but also occupy a large space.

[0050] In order to solve the technical problems of large space occupation and high cost of the traditional variable distance mechanism in the prior art, the present application provides a variable distance positioning device and conveying equipment, which can simultaneously realize the machining positioning of a plurality of workpieces in a first direction and a second direction through a driving member, thereby saving cost and reducing arrangement space.

[0051] Figure 1 A structural schematic diagram of a variable distance positioning device provided for an embodiment of the present application, Figure 2 For Figure 1 A structural schematic diagram of a jig in the variable distance positioning device shown.

[0052] Figure 1 And Figure 2 A variable distance positioning device 1 provided for an embodiment of the present application, comprising a support 11, a first driving mechanism 14, a second driving mechanism 15 and a second cross beam 16.

[0053] At least one first beam 12 is arranged on the support 11 to slide along the first direction X, and the length direction of the first beam 12 is parallel to the second direction Y. It can be understood that the number of the first beam 12 can be one, two, three, and the like, which is not specifically limited here. The first beam 12 is arranged with at least one jig 13 to slide along the second direction Y. It can be understood that the jig 13 can be arranged in one group, two groups, three groups, and the like, which is not specifically limited here.

[0054] The jig 13 includes a support plate 131 fixed on the first beam 12, a first clamping assembly 132 and a second clamping assembly 133 arranged on the support plate 131. The first clamping assembly 132 has a first fixed part 132a and a first moving part 132b arranged oppositely along the first direction X. The second clamping assembly 133 has a second fixed part 133a and a second moving part 133b arranged oppositely along the second direction Y. The first fixed part 132a and the second fixed part 133a are fixedly connected to the support plate 131.

[0055] The first driving mechanism 14 is installed on the support 11, and the first driving mechanism 14 is in transmission connection with one of the first beams 12, for driving the first beam 12 to reciprocate along the first direction X.

[0056] The second driving mechanism 15 is installed on the support 11, and the second driving mechanism 15 is in transmission connection with the second moving part 133b, for driving the second moving part 133b to move relative to the second fixed part 133a.

[0057] The second beam 16 is located between the support plate 131 and the first beam 12, and the number of the second beam 16 corresponds to the number of the support plate 131. The second beam 16 is provided with a follower 17 connected with the first moving part 132b, for driving the first moving part 132b to move relative to the first fixed part 132a.

[0058] For ease of description and understanding, it is assumed that the support 11 is provided with m first cross beams 12, m≥1, and each first cross beam 12 is provided with n jigs 13, n≥1, so that n rows of m columns of jigs 13 can be obtained. For example, in a preferred embodiment, two rows of six columns of jigs 13 are provided. The workpiece to be processed (which can be a battery cell, for example) is placed on the jig 13, and the second driving mechanism 15 can drive the second moving part 133b of the n rows of m columns of jigs 13 to move relative to the second fixed part 133a, so as to adjust the distance between the second moving part 133b and the second fixed part 133a in the second direction Y, and thus achieve accurate positioning of the workpiece to be processed in the second direction Y. Under the drive of the second driving mechanism 15, the follower 17 drives the first moving part 132b of the n rows of m columns of jigs 13 to move relative to the first fixed part 132a, so as to adjust the distance between the first moving part 132b and the first fixed part 132a in the first direction X, and thus achieve accurate positioning of the workpiece to be processed in the first direction X. The first clamping assembly 132 and the second clamping assembly 133 provide stable clamping force for the workpiece to be processed, preventing the workpiece to be processed from shifting during processing, so as to ensure the processing quality of the workpiece to be processed. The first driving mechanism 14 drives the plurality of first cross beams 12 to reciprocate in the first direction X, thereby driving a column of jigs 13 to reciprocate in the first direction X, changing the distance between the column of jigs 13 and another adjacent column of jigs 13, and achieving distance variation between the workpieces to be processed. Compared with the conventional distance variation mechanism which needs to additionally provide positioning mechanisms in the X direction and the Y direction, the distance variation positioning device 1 can achieve processing positioning of the plurality of workpieces to be processed in the first direction X and the second direction Y, and achieve distance variation between the workpieces to be processed, in a limited arrangement space, thereby saving cost and arrangement space, having the advantages of compact structure and high positioning accuracy, and ensuring the processing quality of the workpieces to be processed. All power sources of the distance variation positioning device 1 are driven by air cylinders, which is low in cost and convenient to change.

[0059] The distance variation positioning device 11 provided by the embodiments of the present application will be further described below in combination with the drawings.

[0060] Figure 3 For Figure 1 The structure of the jig and the follower in the distance variation positioning device is shown.

[0061] Optionally, as Figure 3As shown, the support plate 131 and the first cross beam 12 are fixedly connected through the support rod 121, the top of the support rod 121 is fixedly connected to one side of the support plate 131 facing the first cross beam 12, and the bottom of the support rod 121 is fixedly connected to one side of the first cross beam 12 facing the support plate 131. In one jig 13, one, two, three, four, … support rods 121 can be provided. In the embodiment, four support rods 121 are preferably used, which are evenly distributed around the support plate 131 to provide stable support force to the support plate 131.

[0062] In some embodiments, as Figure 1 As shown, the second driving mechanism 15 includes a second cylinder 151 fixedly arranged on the support base 11, the output end of the piston rod of the second cylinder 151 is provided with a first connecting plate 152, and one side of the first connecting plate 152 away from the output end of the piston rod of the second cylinder 151 is provided with a longitudinal beam 153. The extension direction of the piston rod of the second cylinder 151 is parallel to the second direction Y, and the length direction of the longitudinal beam 153 is parallel to the first direction X. Optionally, the cross section of the first connecting plate 152 is in the shape of “Z”, so that the layout of the variable-distance positioning device 11 is more compact, and the top of the first connecting plate 152 can be fixedly connected to the longitudinal beam 153 through bolts. One end of the longitudinal beam 153 away from the first connecting plate 152 is slidingly abutted to the second cross beam 16, and one side of the second cross beam 16 facing the support plate 131 is provided with an elastic transmission mechanism 18 connected with the second moving part 133b.

[0063] It can be understood that when the piston rod of the second cylinder 151 is retracted, the first connecting plate 152 drives the longitudinal beam 153 to move towards the second cross beam 16, so that the longitudinal beam 153 pushes the second cross beam 16 to move along the second direction Y, and under the transmission action of the elastic transmission mechanism 18, the second moving part 133b is away from the second fixed part 133a, thereby adapting to different models and different sizes of workpieces to be processed.

[0064] Optionally, as Figure 3 As shown, one side of the second cross beam 16 away from the support plate 131 is fixedly provided with a first guide rail 161 along the second direction Y, the length direction of the first guide rail 161 is parallel to the second direction Y, and one side of the first cross beam 12 facing the jig 13 is fixedly provided with a first sliding block 162 slidingly connected with the first guide rail 161. Under the sliding cooperation of the first guide rail 161 and the first sliding block 162, the stability of the second cross beam 16 sliding along the second direction Y is improved.

[0065] Optionally, two second cross beams 16 above the same first cross beam 12 can be commonly fixedly provided with a first guide rail 161, so that the second moving parts 133b of the same column of jigs 13 can be simultaneously away from or close to the second fixed parts 133a, thereby reducing the arrangement of driving members and reducing costs.

[0066] Figure 4 ForFigure 1 Structure diagram of the jig, follower and elastic transmission mechanism in the variable-pitch positioning device, Figure 5 As Figure 4 Working principle diagram of the elastic transmission mechanism (wherein the second cylinder piston rod is in the retracted state) Figure 6 As Figure 4 Working principle diagram of the elastic transmission mechanism (wherein the second cylinder piston rod is in the extended state).

[0067] In some embodiments, as Figure 4 shown, the elastic transmission mechanism 18 includes a second connecting plate 181, a first guide sleeve 182, a first guide shaft 183 and a first spring 184 sleeved on the first guide shaft 183. The first guide sleeve 182 is arranged on the side of the support plate 131 facing the second cross beam 16. The first guide shaft 183 is arranged through the first guide sleeve 182 along the second direction Y, and one end of the first guide shaft 183 is fixedly connected with the second moving part 133b, and the other end is fixedly connected with a limiting plate 185. One end of the first spring 184 is fixedly connected with the limiting plate 185, and the other end is fixedly connected with the first guide sleeve 182. The second connecting plate 181 has an “L” shape in cross section, the horizontal segment of the second connecting plate 181 is fixedly arranged on the side of the second cross beam 16 away from the first cross beam 12, and the vertical segment of the second connecting plate 181 abuts against the limiting plate 185 movably.

[0068] It can be understood that, as Figure 5 shown, when the piston rod of the second cylinder 151 is retracted, the longitudinal beam 153 pushes the second cross beam 16 to move along the second direction Y, the second connecting plate 181 moves along the second direction Y with the second cross beam 16, directly abuts against the limiting plate 185 to apply a pushing force to the limiting plate 185, so that the limiting plate drives the first guide shaft 183 to slide on the first guide sleeve 182, thereby driving the second moving part 133b to move away from the second fixed part 133a, and at the same time the first spring 184 is extruded. As Figure 6 shown, when the piston rod of the second cylinder 151 is extended, the first connecting plate 152 drives the longitudinal beam 153 to move away from the second cross beam 16, and under the action of the restoring force of the first spring 184, the second moving part 133b approaches the second fixed part 133a, thereby providing clamping force to the workpiece to be processed, and at the same time completing the positioning of the workpiece to be processed along the second direction Y.

[0069] In some embodiments, as Figure 4As shown, the follower 17 includes a cam 171 and a wedge block 172, the cam 171 is rotationally arranged on the side of the first moving part 132b facing the first beam 12. Optionally, the cam 171 can adopt a rolling bearing, which is fixedly connected with the bottom of the first moving part 132b by bolts. The wedge block 172 is arranged on the second beam 16, and the side of the wedge block 172 facing the cam 171 is arranged as a wedge surface and abuts against the peripheral surface of the cam 171. It can be understood that the thickness of the wedge block 172 in the first direction X gradually decreases along the second direction Y. The side of the first moving part 132b facing the first fixed part 132a is fixedly provided with a third connecting plate 173, and the side of the support plate 131 facing the first beam 12 is provided with a second guide sleeve 174, the second guide sleeve 174 is provided with a second guide shaft 175 penetrating along the first direction X, one end of the second guide shaft 175 is fixedly connected with the third connecting plate 173, the other end is provided with a limiting ring 176, and the second guide shaft 175 is sleeved with a second spring 177, one end of the second spring 177 abuts against the limiting ring 176, and the other end abuts against the second guide sleeve 174.

[0070] Figure 7 For Figure 4 the working principle of the follower is shown.

[0071] As Figure 7 shown, when the piston rod of the second cylinder 151 is retracted, the longitudinal beam 153 pushes the second beam 16 and the wedge block 172 to move along the second direction Y, and under the cooperation of the peripheral surface of the cam 171 and the wedge surface of the wedge block 172, the cam 171 moves along the first direction X, driving the first clamping part to move away from the first fixed part 132a, so as to adapt to different models and different sizes of workpieces to be processed, and at the same time, the first clamping part drives the second guide shaft 175 to move, and the second spring 177 is extruded; when the piston rod of the second cylinder 151 is extended, the first connecting plate 152 drives the longitudinal beam 153 to move away from the second beam 16, and under the restoring force of the second spring 177, the first moving part 132b approaches the first fixed part 132a, so as to provide clamping force to the workpiece to be processed, and at the same time, the positioning of the workpiece to be processed in the first direction X is completed.

[0072] Optionally, as Figure 4 shown, the side of the support plate 131 facing the first beam 12 is fixedly provided with a second guide rail 134 along the first direction X, and the side of the third connecting plate 173 facing the support plate 131 is provided with a second sliding block 135 in sliding connection with the second guide rail 134. Under the sliding cooperation of the second guide rail 134 and the second sliding block 135, the stability of the second moving part 133b beam sliding along the first direction X is improved, and at the same time, the guiding accuracy of the second sliding block 135 is high and will not appear jamming.

[0073] Figure 8 For Figure 1A side view of the variable distance positioning device.

[0074] In some embodiments, as shown in Figure 8 The first driving mechanism 14 includes a first cylinder 141 fixed on the support 11. One of the first cross beams 12 is provided with a fourth connecting plate 142 on the side facing the support 11, and the piston rod output end of the first cylinder 141 is fixedly connected with the fourth connecting plate 142. The piston rod of the first cylinder 141 extends or retracts in parallel with the first direction X.

[0075] By extending or retracting the piston rod of the first cylinder 141, the fourth connecting plate 142 is pushed to reciprocate along the first direction X, thereby driving the jig 13 on the first cross beam 12 to reciprocate along the first direction X, so as to change the position of the workpiece along the first direction X and realize the variable distance between the adjacent two workpieces.

[0076] Figure 9 To Figure 1 A structural schematic view of the variable distance positioning device (part of the structure of the support is hidden).

[0077] In some embodiments, as shown in Figure 9 The support 11 is provided with a recess 111 on the side facing the first cross beam 12, and the first cross beam 12 is provided with a third guide sleeve 122 on the side facing the recess 111. A third guide shaft 123 is arranged between the adjacent two third guide sleeves 122 along the first direction X, one end of the third guide shaft 123 is fixedly connected with one of the third guide sleeves 122, and the other end is slidably connected with the other third guide sleeve 122.

[0078] When the piston rod of the first cylinder 141 retracts, the first cross beam 12 drives the third guide sleeve 122 fixedly connected therewith to move until the third guide sleeve 122 moves to the adjacent other third guide sleeve 122, thereby driving the adjacent other third guide sleeve 122 to move, so that the adjacent column of jigs 13 moves synchronously, thereby sequentially changing the position of the other column of jigs 13 along the first direction X.

[0079] Optionally, when a plurality of columns of jigs 13 are arranged, the middle part of the support 11 can be provided with a boss 112, and one end of the two third guide shafts 123 located in the middle can be fixedly connected with the boss 112.

[0080] In some embodiments, as shown in Figure 9 The adjacent two third guide shafts 123 are arranged in a staggered manner, thereby saving arrangement space and preventing the adjacent two third guide shafts 123 from interfering with each other.

[0081] In a preferred embodiment, two first cylinders 141 are provided, and the two first cylinders 141 are arranged on opposite sides of the support 11, and the piston rods of the two first cylinders 141 are arranged to face opposite directions and are fixedly connected to the outermost first cross beams 12 respectively. Through the above arrangement, one side cylinder controls 2 / m rows of carriers respectively, thereby saving arrangement space.

[0082] Figure 10 For Figure 9 The structure schematic view of the variable-distance positioning device in another direction (in which part of the structure of the support is hidden). In some embodiments, as shown in Figure 10 The side of the first cross beam 12 facing the groove 111 is provided with a position indicating plate 124, and the side wall of the groove 111 is provided with a first position sensor 113 corresponding to the position indicating plate 124, and the sensing direction of the first position sensor 113 faces the position indicating plate 124. Adjacent two first position sensors 113 are arranged in a staggered manner.

[0083] Through the first position sensor 113, the displacement of the position indicating plate 124 in the first direction X can be read, and the distance between adjacent two jigs 13 in the first direction X can be detected, so as to judge whether the X-direction distance of the workpiece to be processed matches the X-direction positioning of the processing equipment.

[0084] Figure 11 For Figure 1 The top view of the variable-distance positioning device is shown. In some embodiments, as shown in Figure 11 The side of the first cross beam 12 facing the adjacent another first cross beam 12 is provided with a limiting block 125. In actual production process, the stroke of the two first cylinders 141 on the opposite side can be changed, or the limiting block 125 can be added to meet various variable-distance requirements.

[0085] In some embodiments, as shown in Figure 8 The support 11 is provided with a bracket 114, and the side of the bracket 114 facing the jig 13 is provided with a second position sensor 115. The second position sensor 115 is used to detect whether the workpiece to be processed is placed on the jig 13, and to determine whether the variable-distance positioning mechanism needs to be fed or unloaded.

[0086] Optionally, the first position sensor 113 and the second position sensor 115 can adopt various types of second position sensors 115 in the prior art, such as potential position sensors, capacitive position sensors, inductive position sensors, optical position sensors, etc.
