[0030] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] The embodiment of the utility model provides a turntable mechanism, which enables the camera to detect the workpiece even if it is arranged on one side of the bottom of the turntable body 1.

[0034] See also Figures 1 to 5 The turntable mechanism includes a turntable body 1, a rotation driving device 2 for driving the turntable body 1 to rotate, and a supporting fixture 3 installed on the turntable body 1. In this embodiment, the turntable body 1 and the supporting fixture 3 can be a combined structure; the turntable body 1 and the supporting fixture 3 can also be an integrated structure, that is, the side of the turntable body 1 extends out of the supporting fixture 3.

[0035] The carrying jig 3 includes a jig body 31, which is provided with a carrying area for placing the workpiece and at least three detection holes 32 opened in the carrying area; the detection holes 32 penetrate the jig body 31 to detect the position of the corners of the workpiece, and a transparent plate 33 is installed in the detection hole 32, and the top surface of the transparent plate 33 is flush with the carrying surface of the carrying area.

[0036] In this embodiment, by providing a detection hole 32 and a transparent plate 33, the detection camera 4 can be installed at the bottom to detect the corners of the workpiece, so that the position of the workpiece is located by at least three corners of the workpiece. It should be noted here that positioning the workpiece by visually detecting the corners of the workpiece belongs to the prior art, so it will not be repeated.

[0037] It should also be noted that the top surface of the transparent plate 33 is flush with the bearing surface of the bearing area, which can avoid the workpiece from being partially lifted or sunken, thereby affecting the actual detection and reducing the positioning detection accuracy. In addition, the top surface of the transparent plate 33 is flush with the bearing surface of the bearing area, which is also conducive to exposing the workpiece. The structure in this embodiment belongs to the field of battery cell preparation. The scheme for preparing circuits on battery cells includes two parts: graphic electroplating and post-processing: graphicization is to coat a photosensitive curing adhesive layer on the surface of the substrate, photocuring part of the photosensitive curing adhesive layer, washing away the photosensitive curing adhesive layer of the unexposed part, and retaining the pattern of the exposed part. Electroplating and post-processing are copper plating in an electroplating device, and an electrochemical reduction reaction occurs on the surface without a photosensitive curing adhesive layer to grow copper; finally, the remaining photosensitive curing adhesive layer is washed away to prepare a graphic circuit. The workpiece in this embodiment is a substrate coated with a photosensitive curing adhesive layer.

[0038] Preferably, the transparent plate 33 is optical glass. The setting of the transparent plate 33 is equivalent to constant light transmittance, which is conducive to improving the detection accuracy. It should be noted here that if the longer length of the detection hole 32 is air, the air is likely to cause the light transmittance to change under the influence of temperature, thereby affecting the actual detection accuracy, and the setting of the transparent plate 33 can effectively reduce the variation range of light transmittance, thereby improving the detection accuracy.

[0039] Optionally, the bearing area is provided with four detection holes 32, and the four detection holes 32 are distributed in a rectangular shape. Specifically, the four detection holes 32 correspond to the four corners of the detection workpiece, so as to better confirm the position of the workpiece. Generally, the workpiece is rectangular.

[0040] Optionally, the bearing fixture 3 is provided with a groove 301 for mounting a transparent plate 33, and the transparent plate 33 is detachably mounted in the groove 301; the detection hole 32 penetrates to the bottom of the groove 301. The cross section of the groove 301 is larger than the detection hole 32, so that the bottom surface of the groove 301 can support the bottom surface of the transparent plate 33, and the top surface of the transparent plate 33 is flush with the bearing surface of the bearing area.

[0041] Optionally, the cross-sectional shape of the detection hole 32 is a circular hole, a rectangular hole, a triangular hole, an elliptical hole or a fan-shaped hole; the shape of the transparent plate 33 matches the shape of the detection hole 32. In this embodiment, the shape of the detection hole 32 is not important, as long as the detection hole 32 can transmit light so that the detection camera 4 at the bottom can detect the corners of the workpiece.

[0042] Optionally, two bearing areas are provided on a fixture body 31; at least one detection hole 32 is located between the two bearing areas, and a portion of the detection hole 32 extends to one bearing area, and another portion of the detection hole 32 extends to the other bearing area. That is, one detection camera can detect the positions of the respective corners of two workpieces at the same time, so that the number of cameras can be reduced, which is conducive to cost saving.

[0043] Optionally, a fixing through hole 331 is provided on the transparent plate 33, and a threaded hole is provided at the bottom of the groove 301; the bearing fixture 3 further includes a threaded fastener, which passes through the fixing through hole 331 and is screwed into the threaded hole to fix the transparent plate 33 in the groove 301. Specifically, the transparent plate 33 is fixed by the threaded fastener, and after the transparent plate 33 is scratched or damaged, the threaded fastener can be removed and a new transparent plate 33 can be replaced.

[0044] Optionally, through holes corresponding to the detection holes 32 are provided on the turntable body 1. Specifically, at this time, the fixture body 31 does not need to be fully extended into the side of the turntable body 1, so that the installation of the fixture body 31 can be simpler and more stable.

[0045] Optionally, the turntable mechanism further includes a detection camera 4; the detection camera 4 is arranged at one side of the bottom of the turntable body 1 to detect the corners of the workpiece through the detection hole 32 and the transparent plate 33. The detection camera 4 is arranged at a specific position, and when the turntable body 1 rotates to a suitable angle, the detection camera 4 faces the detection hole 32, thereby detecting the corner position of the workpiece, and then the industrial control computer can determine the position of the workpiece according to the corner position of the workpiece, thereby improving the subsequent processing accuracy.

[0046] Optionally, the support fixture 3 is provided with a plurality of vacuum adsorption holes 302, which are distributed in an array in the support area. The vacuum adsorption holes 302 adsorb and fix the workpiece to prevent the workpiece from shifting relative to the support fixture 3 during the rotation of the turntable body 1.
