It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0051] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0053] Figure 1 This is a schematic diagram of the structure of a positioning system 100 according to one embodiment of the present disclosure. Figure 2 This is a structural schematic diagram of a positioning system 100 according to one embodiment of the present disclosure from another angle. Figure 3 This is a structural schematic diagram of a portion of the structure of a positioning system 100 according to one embodiment of the present disclosure.

[0054] like Figures 1 to 3As shown, the positioning system 100 disclosed herein may include components such as a base plate 110, a first guide rail assembly 120, a front sliding member 130, a rear sliding member 140, a front positioning member 150, a rear positioning member 160, an upper support plate 170, a second guide rail assembly 180, a left positioning assembly 190, and a right positioning assembly 200.

[0055] exist Figure 1 In the specific implementation shown, the base plate 110 can be fixed to the base by means of a bracket or other components. At this time, the base can be fixed near the automated production line, so that the positioned workpiece can be conveniently transported to the automated production line.

[0056] In this disclosure, the base plate 110 is generally rectangular in shape and may include a first direction and a second direction. In one specific embodiment, the first direction may be the width direction of the base plate 110, and the second direction may be the length direction of the base plate 110.

[0057] The first guide rail assembly 120 is disposed on the base plate 110 and is disposed along the first direction; the front slider 130 and the rear slider 140 are slidably disposed on the first guide rail assembly 120, wherein the front slider 130 and the rear slider 140 can be driven to approach or move away from each other.

[0058] Specifically, the first guide rail assembly 120 of this disclosure may include two first guide rail components, which are respectively disposed at both ends of the base plate 110 in the length direction. Correspondingly, the lengths of the front slider 130 and the rear slider 140 are approximately the same as the length of the base plate 110. In this case, the two ends of the front slider 130 can be slidably disposed on the two first guide rail components by two sliders, and the two ends of the rear slider 140 can also be slidably disposed on the two first guide rail components by two sliders.

[0059] In a preferred embodiment, each first guide rail component can be formed by a single guide rail. In another embodiment, each first guide rail component can be formed by two guide rails, both of which are arranged along the width direction of the base plate 110 and are aligned on the same straight line. Those skilled in the art will understand that even if the two guide rails are not aligned on the same straight line, it is sufficient as long as they are both arranged along the width direction of the base plate 110. In other words, this arrangement enables guidance of the front slider 130 and the rear slider 140.

[0060] The front positioning member 150 is disposed on the front sliding member 130, and the rear positioning member 160 is disposed on the rear sliding member 140. The front positioning member 150 and the rear positioning member 160 are used to position the workpiece in the first direction.

[0061] In other words, when the front sliding member 130 and the rear sliding member 140 slide along the width direction, they can drive the front positioning member 150 and the rear positioning member 160 to move in the first direction, thereby positioning the workpiece in the first direction.

[0062] In one embodiment of this disclosure, the workpiece can be placed on a carrier, which can be positioned by a front positioning member 150 and a rear positioning member 160, thereby enabling the workpiece to be positioned by the front positioning member 150 and the rear positioning member 160. In another embodiment, the workpiece can also be placed directly on a support plate and positioned by the front positioning member 150 and the rear positioning member 160.

[0063] In one specific embodiment, a front positioning member 150 and a rear positioning member 160 can form a front-to-back positioning assembly. In this disclosure, multiple sets of front-to-back positioning assemblies can be configured, thereby enabling the positioning system 100 of this disclosure to position multiple workpieces simultaneously.

[0064] like Figure 1 As shown, the positioning components in the front-to-back direction of this disclosure may include five groups, and the positioning components in the front-to-back direction can be evenly distributed along the second direction, thereby enabling the positioning of five workpieces at equal intervals.

[0065] In this disclosure, the position of the front positioning member 150 relative to the front sliding member 130 in the first direction is adjustable; and / or, the position of the rear positioning member 160 relative to the rear sliding member 140 in the first direction is adjustable. Thus, during the debugging process of the positioning system 100, the positions of the front positioning member 150 and the rear positioning member 160 can be adjusted so that the front positioning member 150 and the rear positioning member 160 at different positions can stably and accurately position the workpiece at that position.

[0066] In a preferred embodiment, the front positioning member 150 can be disposed on the front sliding member 130 via the front connecting block 210, and similarly, the rear positioning member 160 can be disposed on the rear sliding member 140 via the rear connecting block 220. Specifically, the front connecting block 210 and the rear connecting block 220 of this disclosure have the same structure. The front sliding member 130 is provided with a first toothed portion, and the front connecting block 210 can be formed with a toothed structure that mates with the first toothed portion. The rear sliding member 140 is provided with a second toothed portion, and the rear connecting block 220 is formed with a toothed structure that mates with the second toothed portion. Accordingly, after the positions of the front positioning member 150 and the rear positioning member 160 are adjusted, the front connecting block 210 can be fixed to the front sliding member 130, and the rear connecting block 220 can be fixed to the rear sliding member 140. At this time, by setting the mate toothed structure, it is possible to prevent the front connecting block 210 from displacing relative to the front sliding member 130 in the first direction, and to prevent the rear connecting block 220 from displacing relative to the rear sliding member 140 in the first direction. Thus, the positioning system of this disclosure can have higher positioning accuracy in the first direction.

[0067] In a preferred embodiment, the teeth of the first toothed portion and the second toothed portion extend in a direction substantially perpendicular to the first direction, thereby enabling the front positioning member 150 and the front sliding member 130 to be securely fixed together, and similarly, enabling the rear positioning member 160 and the rear sliding member 140 to be securely fixed together.

[0068] In this disclosure, taking the front connecting block 210 as an example, the front connecting block 210 has an elongated groove. The length direction of the elongated groove is the same as the first direction. The screw can pass through the elongated groove and fix the front connecting block 210 to the front sliding member 130. Thus, when the screw is located at different positions in the elongated groove, the position between the front positioning member 150 and the front sliding member 130 can be adjusted. Since the connection method between the rear connecting block 220 and the rear sliding member 140 is the same as the connection method between the front connecting block 210 and the front sliding member 130, this disclosure will not elaborate further.

[0069] The second guide rail component 180 is disposed on the base plate 110 and is arranged along the second direction; in this disclosure, the second guide rail component 180 can be configured as one. Those skilled in the art should know that the second guide rail component 180 can also be configured as two, and the two second guide rail components 180 are arranged in parallel.

[0070] Both the left positioning component 190 and the right positioning component 200 are slidably disposed on the second guide rail component 180. The left positioning component 190 and the right positioning component 200 can be driven to approach or move away from each other, and the workpiece is positioned in the second direction by the left positioning component 190 and the right positioning component 200.

[0071] In this disclosure, the second guide rail component 180 is provided with a first sliding member 230 and a second sliding member 240, wherein the left positioning component 190 is mounted on the first sliding member 230 and the right positioning component 200 is mounted on the second sliding member 240, thereby the left positioning component 190 and the right positioning component 200 of this disclosure can be driven and moved independently.

[0072] In one specific embodiment, the second guide rail component 180 is located above the base plate 110; thus, in the positioning system 100 of this disclosure, movement along the first direction and movement along the second direction can be independent of each other.

[0073] The second guide rail component 180 is provided with a first slider and a second slider. The first slider 230 is fixed to the first slider, and the second slider 240 is fixed to the second slider. Thus, the first slider 230 of this disclosure can slide relative to the second guide rail component 180, and the second slider 240 can also slide relative to the second guide rail component 180. Furthermore, the left positioning component 190 and the right positioning component 200 can approach or move away from each other.

[0074] At least a portion of the second slider 240 is located inside the first slider 230. In one specific embodiment, the first slider 230 has an opening groove, at least a portion of the second slider 240 is located within the opening groove, and the first slider 230 and the second slider 240 are capable of relative movement. At this time, the second slider 240 can be positioned directly above the second guide rail component 180, and the first slider 230 can be positioned slightly above the side of the second guide rail component 180, and both the first slider 230 and the second slider 240 can operate stably on the second guide rail component 180.

[0075] In a preferred embodiment, the first slider 230 is driven by a first driving device, wherein the first driving device is a cylinder; and / or, the second slider 240 is driven by a second driving device, wherein the second driving device is a cylinder. That is, the first slider 230 and the second slider 240 of this disclosure are driven independently, thereby facilitating the control of the positioning system during the workpiece positioning process.

[0076] In this disclosure, the left positioning component 190 includes two positioning posts; and / or, the right positioning component 200 includes two positioning posts; correspondingly, the left positioning component 190 can be located on the left side of the workpiece, and the right positioning component 200 can be located on the right side of the workpiece. Moreover, the two positioning posts of the left positioning component 190 are arranged along a first direction, and the two positioning posts of the right positioning component 200 are also arranged along a first direction.

[0077] Furthermore, the front slider 130 and the rear slider 140 of this disclosure are driven by a finger-clamping cylinder. Specifically, the front slider 130 and the rear slider 140 are respectively fixed to the two fingers clamped by the finger-clamping cylinder, so that when the finger-clamping cylinder moves, the front slider 130 and the rear slider 140 can move synchronously in opposite directions.

[0078] In a preferred embodiment, an upper support plate 170 is disposed on a base plate 110; wherein the upper support plate 170 is used to support a workpiece or a carrier for placing a workpiece. Specifically, the carrier or workpiece to be positioned can be placed on the support plate 170 and can slide relative to the support plate 170. In addition, at least a portion of the front positioning member 150, the rear positioning member 160, the left positioning assembly 190, and the right positioning assembly 200 can be located above the support plate 170, so that the front positioning member 150, the rear positioning member 160, the left positioning assembly 190, and the right positioning assembly 200 can operate on the carrier or workpiece and position the carrier or workpiece.
