Description

Technical Field

[0001] This utility model relates to the field of automated machinery, specifically to a centering and positioning unit that can be applied to center and position plate-shaped products in an automated production line. Background Technology

[0002] In automated production, it is often necessary to center and position products. For example, before a product is picked up and processed by a robotic arm, a centering and positioning device is needed to position the product so that the robotic arm can pick it up accurately. Another example is that before plate-shaped products, such as battery covers, are inspected, a centering and positioning device is also needed to position the battery cover so that it accurately enters the inspection area, thereby ensuring the reliability and accuracy of the inspection.

[0003] The existing centering and positioning devices have the following shortcomings:

[0004] On the one hand, two sets of positioning devices are required in the X-axis and Y-axis directions respectively to center and position the product, which is complex in structure and has low space utilization.

[0005] On the other hand, when performing centering and positioning operations, two centering and positioning actions need to be performed separately, resulting in low positioning efficiency.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] The purpose of this invention is to provide a centering and positioning unit for plate-shaped products.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A centering and positioning unit for a plate-shaped product includes a set of paired centering and positioning devices.

[0010] Each of the centering and positioning devices includes a second clamping part and a set of first clamping parts arranged opposite to each other along the X-axis direction, and the two second clamping parts in the pair of centering and positioning devices are arranged opposite to each other along the Y-axis direction.

[0011] Each of the two first clamping parts in the centering and positioning device is driven to move closer or further away from each other along the X-axis direction, and limits the two sides of the product end in the X-axis direction.

[0012] The two second clamping parts of the two centering and positioning devices are driven to move closer or further apart from each other along the Y-axis, and limit the two ends of the product in the Y-axis direction.

[0013] In a further technical solution, each of the first clamping parts is also positioned and connected to an inclined surface, and a rolling part is rolled on the inclined surface of each of the inclined surfaces. The rolling part is driven to move along the Y-axis direction and rolls on the inclined surface of the inclined surface, squeezing the two inclined surfaces and causing the two first clamping parts to move closer to each other in the X-axis direction.

[0014] In a further technical solution, the inclined surfaces of the two inclined surfaces are axially symmetrically distributed along the center line of the centering and positioning device in the Y-axis direction, and the plane containing each inclined surface intersects the center line.

[0015] In a further technical solution, the driving structure drives the mounting base of the rolling part to move along the Y-axis direction, and the outer end of the second clamping part is directly or indirectly connected to the mounting base, thereby driving the second clamping part to move in the Y-axis direction through the Y-axis movement of the mounting base; at the same time, the rolling part drives the first clamping part to move along the X-axis direction through the inclined part, thereby realizing that the first clamping part and the second clamping part are both driven by the same driving structure to simultaneously limit and clamp the plate-shaped product in the X-axis and Y-axis directions.

[0016] In a further technical solution, each centering and positioning device also includes a sliding guide rail, which is arranged along the X-axis, and the first clamping part is slidably disposed on the sliding guide rail.

[0017] A further technical solution also includes a first elastic element, which acts on the first clamping part to keep the two first clamping parts in an opening and closing motion tendency.

[0018] A further technical solution also includes a second elastic member, which acts between the mounting base of the rolling part and the second clamping part, and keeps the mounting base of the rolling part moving away from the second clamping part.

[0025] The working principle and advantages of this utility model are as follows:

[0026] This utility model's centering and positioning device includes a second clamping part for clamping and positioning both ends of a plate-shaped product in the Y-axis direction, and a first clamping part for clamping and positioning both sides of the plate-shaped product in the X-axis direction. The first and second clamping parts can be driven by the same drive structure, simultaneously achieving clamping and positioning of the plate-shaped product in both directions. On the one hand, integrating the clamping parts for positioning in both directions into a single positioning device saves space; on the other hand, during the centering and positioning operation, positioning in both the X and Y axes can be completed with a single drive action by the same drive mechanism, helping to improve the overall cycle time of automated production and thus increase production efficiency.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0035] Please see Figures 1-3 A centering and positioning unit for a plate-shaped product includes a set of centering and positioning devices 5 arranged opposite to each other on both sides of the width direction of the conveying device 23. The centering and positioning devices 5 can solve the problem of resetting the battery cover 6 due to positional shift caused by long-distance transportation, which is beneficial to ensuring the accuracy and reliability of the front and back detection of the battery cover 6. Therefore, the centering and positioning devices 5 can be set at the front end of the front detection area 231 and the front end of the back detection area 232 on the conveying device 23 to correct their own position before passing through the front detection area 231 and the back detection area 232.

[0036] like Figure 1 As shown, the centering and positioning device 5 includes a second clamping part 52 and a set of first clamping parts 51 arranged opposite each other along the X-axis direction, and the two second clamping parts 52 in the paired centering and positioning devices 5 are arranged opposite each other along the Y-axis direction; the two first clamping parts 51 in each centering and positioning device 5 are driven to move closer or further away from each other along the X-axis direction, and limit the two sides of the end of the battery cover plate 6 in the X-axis direction; the two second clamping parts 52 of the two centering and positioning devices 5 are respectively driven to move closer or further away from each other along the Y-axis direction, and limit the two ends of the battery cover plate 6 in the Y-axis direction.

[0037] Optionally, both the first clamping part 51 and the second clamping part 52 include a POM (polyoxymethylene) cylindrical bushing, and the POM (polyoxymethylene) cylindrical bushing is used to contact the battery cover plate 6. POM (polyoxymethylene) has the characteristic of good wear resistance. The cylindrical bushing has a small contact area with the battery cover plate 6, which further reduces the risk of damage to the battery cover plate 6, and can be adapted to more models of battery cover plate 6.

[0038] Please continue reading Figure 1 Each of the first clamping parts 51 is also positioned and connected to an inclined part 53. A rolling part 54 is rolled on the inclined surface of each of the inclined parts 53. The rolling part 54 is driven to move along the Y-axis direction and rolls on the inclined surface of the inclined part 53 at the same time, squeezing the two inclined parts 53 and driving the two first clamping parts 51 to move closer to each other in the X-axis direction until the two first clamping parts 51 contact the battery cover plate 6.

[0039] Furthermore, the inclined surfaces of the two inclined surfaces 53 are symmetrically distributed along the center line 1 of the centering and positioning device 5 in the Y-axis direction, and the plane containing each inclined surface intersects the center line 1.

[0040] In this embodiment, as Figure 1 As shown, when the inclined surfaces of the two inclined surfaces 53 are in a "figure-eight" shape, the rolling part 54 moves closer to the conveying device 23 along the Y-axis direction, thereby squeezing the inclined surface 53 and driving the two first clamping parts 51 to move closer to each other along the X-axis direction. Conversely, the rolling part 54 moves away from the conveying device 23, and the two first clamping parts 51 can move away from each other along the X-axis direction through the action of the elastic element.

[0041] Optionally, the beveled surface 53 is a wedge.

[0042] In this embodiment, the driving structure (not shown in the figure, but may be a cylinder or a motor) drives the mounting base of the rolling part 54 to move along the Y-axis direction. The outer end of the second clamping part 52 is directly or indirectly connected to the mounting base. Therefore, the second clamping part 52 can be driven to move in the Y-axis direction by the Y-axis movement of the mounting base. At the same time, the rolling part 54 drives the first clamping part 51 to move along the X-axis direction through the inclined part 53, so as to ensure that the first clamping part 51 and the second clamping part 52 can both achieve the limit clamping of the battery cover plate 6 in the X-axis direction and the Y-axis direction through the same driving structure.

[0043] Furthermore, each centering and positioning device 5 also includes a sliding guide rail 56, which is arranged along the X-axis, and the first clamping part 51 is slidably disposed on the sliding guide rail 56.

[0044] In this embodiment, a first elastic element (not shown in the figure) is also included. This first elastic element acts on the first clamping part 51, causing the two first clamping parts 51 to maintain an opening motion tendency. A second elastic element 55 is also included. This second elastic element 55 acts between the mounting base of the rolling part 54 and the second clamping part 52, and causes the mounting base of the rolling part 54 to maintain a motion tendency away from the second clamping part 52. When the driving structure (such as a cylinder) drives the rolling part 54 to move along the Y-axis, it first overcomes the tension of the second elastic element 55, and at the same time generates a thrust on the second clamping part 52 in the Y-axis. This thrust, supported by the tension of the second elastic element 55, ensures stable positioning of the battery cover 6 in the Y-axis direction. When the rolling part 54 moves along the Y-axis, it acts on the inclined part 53, causing the first clamping part 51 to overcome the tension of the first elastic element and move in the X-axis direction, thereby achieving clamping and positioning of the battery cover 6 in the X-axis direction. In this way, the positioning of the battery cover 6 in both the X-axis and Y-axis directions can be achieved using the same driving structure.

[0045] Optionally, the first elastic element is a spring, and the second elastic element 55 is a spring.

[0046] like Figure 3 As shown, the centering and positioning device 5 is at least located at the rear end of the flipping devices 24a and 24b on the conveying device 23.

[0047] By setting up the centering and positioning device 5, on the one hand, the clamping part used to position the battery cover 6 in the X-axis and Y-axis directions is integrated into a positioning device, which can save equipment space; on the other hand, when performing the centering and positioning action, the positioning in both the X-axis and Y-axis directions can be completed by performing a single driving action through the same driving mechanism, which helps to improve the overall cycle time of automated production and thus improve production efficiency.

[0048] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
