[0001] The present application relates to the technical field of fishing gear processing equipment, and in particular to a batch clamp device for automated spraying. Background Art

[0002] Lures are artificial baits that imitate the behavior and appearance of fish. They attract the attention of fish and make them bite the lures by simulating the appearance, swimming style, smell and taste of fish. When processing lures, they often need to be sprayed to achieve a realistic effect. At present, the market mainly adopts the manual spraying operation method, in which operators hold spray guns to spray paint the lures hanging on the assembly line. This method has high labor costs and low efficiency, and the positioning of the lures hanging on the assembly line is inaccurate, which affects the quality of the spraying. Therefore, the automated production of lure spraying is an inevitable development trend.

The following problems exist in the fixture clamping step: on the one hand, how to realize the clamping of lures in batches to improve efficiency; on the other hand, how to ensure that each clamped lure maintains a consistent position in each operation link of the automated production line to prevent deviations in the spraying and reduce the yield rate.

It should also be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense.

For those skilled in the art, the specific meanings of the above terms in this application can be specifically understood.

[0049] like Figure 1 and Figure 2 The batch clamp device for automatic spraying provided by the embodiment of the present application shown in the figure, the y-axis direction in the figure represents the horizontal clamping direction, the x-axis direction represents another horizontal direction perpendicular to the y-axis, and the z-axis represents the vertical direction. It can be seen from the figure that the batch clamp device includes a substrate 11, and a transmission component 12 and a clamping component 13 are provided on the substrate 11. The clamping component 13 is used to fix and clamp the head and tail ends of the lure 9, and the transmission component 12 is used to drive the lure 9 to rotate. The batch clamp device can clamp multiple lures 9 and make multiple lures 9 rotate synchronously to the specified position, so that the subsequent spraying device can perform batch spraying operations on the specified position.

[0050] Specifically, Figure 3 and Figure 4 As shown, the clamping assembly 13 includes a first clamping group 131 and a second clamping group 132 which are oppositely arranged on both sides of the substrate 11 along the y-axis direction (i.e., the clamping direction), the first clamping group 131 and the second clamping group 132 are respectively used to clamp the head and tail ends of the fake bait 9, the first clamping group 131 includes a plurality of clamping units 133 arranged on one side of the substrate 11 along the x-axis direction, the second clamping group 13 includes a plurality of clamping units 133 correspondingly arranged on the other side of the substrate 11, that is, the clamping units 133 in the first clamping group 131 and the clamping units 133 symmetrically arranged in the second clamping group 132 along the y-axis direction together constitute a group of clamping kits, the same group of clamping kits is used to clamp the head and tail ends of a fake bait 9, and a plurality of groups of clamping kits are arranged in the clamping assembly 13 along the x-axis direction.

[0051] The transmission assembly 12 includes a first synchronous transmission group 122, a second synchronous transmission group 123 and a first driving shaft 121. The first synchronous transmission group 122 and the second synchronous transmission group 123 are respectively arranged corresponding to the first clamping group 131 and the second clamping group 132, and are used to drive the first clamping group 131 and the second clamping group 132 to rotate; the first driving shaft 121 is respectively connected to the same end of the first synchronous transmission group 122 and the second synchronous transmission group 123, and one end of the first driving shaft 121 is used to be connected to the motor shaft of the driving motor, and the first synchronous transmission group 122 and the second synchronous transmission group 123 are connected and transmitted through the first driving shaft 121.

[0052] Specifically, the first synchronous transmission group 122 includes a first bracket 1221, and a first driving wheel 1222 and a plurality of driven wheels 1224 arranged in sequence on the first bracket 1221 along the x-axis direction. The first bracket 1221 extends along the x-axis direction and is connected to the side of the first clamping group 131 on the substrate 11 away from the lure 9, and is used to limit the positions of the first driving wheel 1222 and the plurality of driven wheels 1224. The first driving wheel 1222 and the adjacent driven wheel 1224, as well as two adjacent driven wheels 1224, are connected by a transmission connector 1223 to transmit power; each driven wheel 1224 is coaxially connected to the clamping unit 133 corresponding to it for transmission.

[0053] like Figure 3 and Figure 4 In the preferred embodiment shown, the first driving wheel 1222 and the driven wheel 1224 are both pulleys, and the transmission connecting member 1223 is a belt, and the transmission is achieved by arranging the belt between two adjacent pulleys; in some other optional embodiments, the first driving wheel 1222 and the driven wheel 1224 can also be sprockets, and the corresponding transmission connecting member 1223 is a chain, and the transmission is also achieved by arranging the chain between two adjacent sprockets; in addition, the first driving wheel 1222 and the driven wheel 1224 can also be gears, in which case the transmission connecting member 1223 is a gear, which is arranged between two adjacent driving wheels and driven wheels for transmission.

[0054] The structure of the second synchronous transmission group 123 is similar to that of the first synchronous transmission group 122, and includes a second bracket 1231, a second driving wheel 1232 and a plurality of driven wheels 1224 which are symmetrically arranged with the first synchronous transmission group 122, and each driven wheel 1224 is coaxially connected to the clamping unit 133 arranged corresponding thereto, and the second driving wheel 1232 and the adjacent driven wheel 1224, as well as two adjacent driven wheels 1224, are connected via a transmission connecting member 1223. The specific structure of each component in the second synchronous transmission group 123 and the connection relationship therebetween can refer to the first synchronous transmission group 122, and will not be repeated here.

[0055] The first driving shaft 121 is vertically arranged relative to the first bracket 1221 and the second bracket 1231, and one end of the first driving shaft 121 is used to connect with the motor shaft of the driving motor, and the first driving wheel 1222 and the second driving wheel 1232 are sleeved thereon. When in use, the driving motor drives the first driving shaft 121 to rotate, and then drives the first driving wheel 1222 and the second driving wheel 1232 sleeved thereon to rotate, and then drives each driven wheel 1224 in the two driving wheel groups to rotate synchronously, so as to drive each clamping unit 133 to rotate synchronously, thereby ensuring that the head and tail ends of the lures 9 clamped by each clamping kit rotate synchronously.

[0056] Since the driven wheels 1224 are transmitted through the transmission connector 1223, there will be some mechanical losses when the power is transmitted. Especially when the number of driven wheels 1224 is too large, it may cause the power transmitted to the driven wheel 1224 far away from the first driving shaft 121 to be small, thereby affecting the synchronous rotation of each lure 9. Therefore, in some preferred embodiments, the transmission assembly 12 also includes an auxiliary driven wheel group 124, and the auxiliary driven wheel group 124 includes an auxiliary driving shaft 1241, a first auxiliary driving wheel 1242, a second auxiliary driving wheel 1243, a first auxiliary driven wheel 1244, and a second auxiliary driven wheel 1245;

[0057] The auxiliary drive shaft 1241 is parallel to the first drive shaft 121 and is located on a side of the first synchronous transmission group 122 and the second synchronous transmission group 123 away from the first drive shaft 121, and the auxiliary drive shaft 1241 is connected to the first drive shaft 121 for transmission;

[0058] Furthermore, a first auxiliary driven wheel 1244 and a second auxiliary driven wheel 1245 are sleeved on the auxiliary drive shaft 1241; the first auxiliary driven wheel 1244 and each driven wheel 1224 in the first synchronous transmission group 122 are in the same plane, and the first auxiliary driven wheel 1244 and the driven wheel 1224 in the first synchronous transmission group 122 adjacent thereto are connected via a transmission connecting member 1223; similarly, the second auxiliary driven wheel 1245 and each driven wheel 1224 in the second synchronous transmission group 123 are in the same plane, and are connected to the driven wheel 1224 adjacent thereto via a transmission connecting member 1223.

[0059] Specifically, the first auxiliary driving wheel 1242 and the second auxiliary driving wheel 1243 are respectively arranged on the first driving shaft 121 and the auxiliary driving shaft 1241, the first auxiliary driving wheel 1242 and the second auxiliary driving wheel 1243 are in the same plane, and are both located on the side of the first synchronous transmission group 122 away from the first clamping group 131, and the first auxiliary driving wheel 1242 and the second auxiliary driving wheel 1243 are connected for transmission;

[0060] When the driving motor drives the first driving shaft 121 to rotate, the first driving shaft 121 drives the first auxiliary driving wheel 1242 to rotate, and then drives the second auxiliary driving wheel 1243 to rotate. The rotation of the second auxiliary driving wheel 1243 drives the auxiliary driving shaft 1241 to rotate, and then drives the first auxiliary driven wheel 1244 and the second auxiliary driven wheel 1245 mounted thereon to rotate, thereby supplementing the power of the driven wheel 1224 far away from the end of the first driving shaft 121, so as to ensure the synchronization of the rotation of each driven wheel 1224.

[0061] Since the clamp device in the present embodiment can clamp the head and tail ends of a batch of fake baits 9 and rotate synchronously, so that different surfaces of the clamped multiple fake baits 9 can be sprayed at the same time during the subsequent automated spraying operation, and in order to ensure the consistency of the spraying, on the one hand, the positions and angles of the clamped fake baits 9 are required to be consistent, and on the other hand, stable clamping is required to prevent the fake baits 9 from shaking due to the torque during rotation or the impact force during spraying, thereby affecting the spraying effect; for this reason, the structure of the clamping assembly 13 is further optimized, one end of the fake bait 9 is fixedly clamped, and the other end is retractably clamped, and the fixed clamping of one end ensures that one end of each fake bait 9 is on the same clamping reference plane, and the retractable clamping of the other end provides an elastic clamping space for the fake bait 9, which is convenient for the clamping operation and can ensure the stability of the clamping;

[0062] Specifically, Figure 4-Figure 7 As shown, the clamping assembly 13 further includes a telescopic assembly 134, which is arranged on the outer side of the second synchronous transmission group 123 and cooperates with the driven wheel 1224 located on the same side thereof; the clamping unit 133 is connected to the driven wheel 1224 through the telescopic assembly 134, so that the clamping unit 133 can be fixed relative to the driven wheel 1224 in the circumferential direction, and the clamping unit 133 can be displaced relative to the driven wheel 1224 along the clamping direction (i.e., the y-axis direction), that is, there is an elastic clamping space between the two clamping units 133 of the same clamping kit;

[0063] The telescopic assembly 134 includes a first connecting rod 1341, a second blocking portion 1342 and a spring 1343. The second blocking portion 1342, the first connecting rod 1341, the driven wheel 1224 and the clamping unit 133 are all coaxially arranged. One end of the first connecting rod 1341 passes through the fixed connection between the driven wheel 1224 and the clamping unit 133, and the other end of the first connecting rod 1341 is connected to the second blocking portion 1342. The diameter of the second blocking portion 1342 is larger than the diameter of the first connecting rod 1341. The spring 1343 is sleeved on the first connecting rod 1341, and its two ends are respectively connected to the driven wheel 1224 and the second blocking portion 1342. When clamping, the spring 1343 is compressed or stretched to drive the clamping unit 133 to move along the y-axis direction, which is conducive to more convenient clamping.

[0064] Furthermore, the first connecting rod 1341 is connected to the driven wheel 1224 by respectively providing matching key and pin structures so that the two are circumferentially fixed to transmit torque;

[0065] Furthermore, the first connecting rod 1341 is further provided with a positioning groove 13411, which cooperates with the positioning piece 135 sleeved on the first connecting rod 1341 to locate the position of the clamping unit 133 on the first connecting rod 1341, which can ensure the consistency of the positions of the clamping units 133 on the one hand, and ensure accurate positioning when the clamping units 133 are disassembled and replaced on the other hand;

[0066] In some preferred embodiments, the spring 1343 is in a compressed state and is sleeved on the first connecting rod 1341. When clamping is completed, the elastic force generated by the recovery of the spring provides sufficient tension for the clamped lure 9 to prevent the lure 9 from shaking and maintain the clamping stability of the lure 9.

[0067] In some other preferred embodiments, the clamping unit 133 is a detachable structure, so as to facilitate the replacement / cleaning of each component, and to achieve the goal of firmly fitting each component together so that no position deviation occurs under the action of external force. Fig.10 As shown, the clamping unit 133 includes a positioning pin 1333 and a hook assembly, an elastic body 1334, and a clamping base 1335 connected in the same axial direction; specifically, the end of the hook assembly is connected with a positioning pin 1333 extending radially outward, the end of the hook assembly is detachably connected to the front end of the clamping base 1335, and the end of the positioning pin 1333 passes through the side wall of the clamping base 1335;

[0068] The end side wall of the front end of the clamping base 1335 is provided with a limiting connecting groove 13351 that cooperates with the positioning pin 1333, and the limiting connecting groove 13351 is at least arranged to extend along three different directions of the clamping base 1335, and the end is a blind end, and the at least three different directions are axial, circumferential, and axial respectively; the clamping base 1335 is an internally hollow cylindrical structure, and the rear end of the clamping base 1335 is closed, the elastomer 1334 is accommodated in the interior of the clamping base 1335, and is elastically deformed under the compression of the hook assembly, and the elastic force of the elastomer 1334 transmits the axial force of the groove wall at the end of the limiting connecting groove 13351 to the positioning pin 1333.

[0069] Furthermore, the hook assembly includes a detachably connected positioning connector 1330, a limiting hook 1331 and a connecting base 1332, the outer surface of the connecting base 1332 facing away from the positioning pin 1333 is provided with a limiting groove, one end of the limiting hook 1331 is coaxially connected to the limiting groove of the connecting base 1332, and its axial and radial displacements are limited by the inner wall of the limiting groove, the other end of the limiting hook 1331 extends outward along its axial direction in a hook shape, and is used to hook the circular hanging ring 9a of the lure 9.

[0070] Furthermore, the present application further optimizes the structure of the limit hook 1331 to achieve precise positioning of the lure 9 and ensure accurate position during clamping, so as to avoid omissions, overlaps or position deviations during spraying due to inaccurate initial position of the lure 9, resulting in different spraying effects of each lure.

[0071] Specifically, Figure 12-Figure 15 As shown, the limiting hook 1331 is an integrated plate structure extending along the y-axis direction and having a thickness along the z-axis direction, and includes a handle 13312 and a hook portion 13313 which are sequentially connected along the y-axis direction, the handle 13312 is a long, wide-surface plate structure, and its wide surface can be used as a positioning reference surface when the limiting hook 1331 is installed in the clamp device, one end of the hook portion 13313 is connected to the handle 13312, and the other end is bent into a hook shape along the wide surface of the handle 13312 toward its side, that is, the hook portion 13313 is in a U-shape on the xy plane, so as to be matched with the circular hanging rings 9a at both ends of the lure 9.

[0072] Further, the inner wall of the hooking portion 13313 has a limiting connection surface, which includes a vertical surface 13313-1a, an inner curved surface 13313-2a and an inclined surface 13313-3a, wherein the two sides of the inner curved surface 13313-2a are tangent to the vertical surface 13313-1a and the inclined surface 13313-3a respectively, and the vertical surface 13313-1a is parallel to the yz plane, and is used to orient the hook and assist in limiting when connected to the circular hook 9a; the inclined surface 13313-3a extends in a direction inclined at an angle α to the negative y-axis, preferably, the angle α is in the range of 30-50°, on the one hand, maintaining a sufficiently large angle to facilitate hooking with the hook, and on the other hand, preventing the hook from slipping out of the limiting hook 1331 when the lure 9 rotates due to an excessively large angle; In one step, when the inner curved surface 13313-2a is observed in the positive direction of the y-axis, the inner curved surface 13313-2a is an arc-shaped curved surface structure. Specifically, the arc-shaped curved surface structure specifically refers to a structure in which the intersection line A1 of the inner curved surface 13313-2a and the xy plane is an arc and the intersection line A2 of the inner curved surface 13313-2a and the yz plane is a straight line. Preferably, the intersection line A1 has the same curvature as the cross-sectional circle of the circular hanging ring 9a. When the circular hanging ring 9a is connected to the limit hook described in the present application, the circular hanging ring 9a is inserted by the tip 13313-3, and firstly, the clamping direction thereof is limited so that the circular hanging ring 9a moves along the extension direction of the vertical surface 13313-1a, and then is clamped into the inner curved surface 13313-2 matched therewith, so as to achieve precise positioning during clamping;

[0073] In some preferred embodiments, when the inner curved surface 13313-2a is observed in the positive direction of the y-axis, the inner curved surface 13313-2a presents a saddle surface-like structure, that is, a parabola opening upward is constructed on the xy plane, and then a parabola opening downward is constructed on the yz plane, the tops of the two parabolas coincide at one point, and then the first parabola is allowed to slide on the other parabola to form a saddle surface; preferably, the intersection A1 of the inner curved surface 13313-2a and the xy plane presents an arc line consistent with the cross-sectional circular curvature of the circular hanging ring 9a, and the intersection A2 of the inner curved surface 13313-2a and the yz plane presents an arc line consistent with the inner circular curvature of the circular hanging ring 9a; the inner curved surface 13313-2a of the saddle surface-like structure forms a surface contact with the circular hanging ring 9a, which further improves the connection stability between the two compared with the line contact between the arc-shaped curved surface structure and the circular hanging ring 9a.

[0074] In some preferred embodiments, the first synchronous transmission group 122 is fixedly connected to the base plate 11, and the second synchronous transmission group 123 is movably connected relative to the base plate 11 along the y-axis direction to adapt to clamping lures 9 of different lengths;

[0075] In some specific embodiments, Figure 8 As shown, the clamp device includes a limit adjustment mechanism 15, and the second bracket 1231 is movably connected to the substrate 11 through the limit adjustment mechanism 15. The limit adjustment mechanism 15 includes a plurality of limit holes 151 arranged on the substrate along the y-axis direction (clamping direction), and a limit pin 152 cooperating with the limit hole 151. A through hole cooperating with the limit pin 152 is correspondingly provided on one side of the second bracket 1231. When in use, the limit pin 152 passes through the through hole on the second bracket 1231 and is connected to the corresponding limit hole 151. By adjusting the position of the second bracket 1231 on the substrate 11, the relative distance between the second bracket 1231 and the first bracket 1221 can be adjusted to adapt to the clamping of baits 9 of different lengths; preferably, the limit adjustment mechanism 15 includes two groups, which are respectively arranged on both sides of the substrate 11 to improve the connection stability.

[0076] Optionally, the above-mentioned limit adjustment mechanism 15 can also be realized by key connection, threaded connection, etc., that is, as long as the second synchronous transmission group 123 can be movably connected relative to the base plate 11 along the y-axis direction.

[0077] In some preferred embodiments, in order to make the clamp device of the present application better adaptable to automated production line production, the transmission assembly 12 also includes a clutch 125, which is arranged at the end of the first drive shaft 121, and is used to connect with the motor shaft of the drive motor at a designated station, thereby driving the transmission assembly 12 to drive the clamped lure 9 to rotate to a specific angle for spraying operation. Furthermore, the outer end surface of the clutch 125 is provided with a clutch connection hole 1251 that matches the output end of the motor shaft of the drive motor. In the prior art, the structure of the clutch connection hole 1251 is mostly hexagonal. However, the alignment of this structure is poor. For this reason, in some preferred embodiments, the structure of the clutch connection hole 1251 is further optimized. Specifically, as Fig. 9 As shown, the outer end surface of the clutch 125 is provided with a plurality of clutch connection holes 1251 uniformly distributed circumferentially around its axis. Preferably, the clutch connection holes 1251 are circular structures for engaging with the two eccentric shafts at the output end of the drive motor and transmitting power to achieve fast and accurate docking between the motor shaft of the drive motor and the clutch 125.

[0078] In some preferred embodiments, the clamp device further includes a cover body 14, as shown in Figure 3, which is detachably connected to the base plate 11 to prevent the transmission component 12 from falling paint during the spraying operation, thereby affecting its cleaning and use effect.

[0079] In some preferred embodiments, the substrate 11 is provided with a first cavity 111, which is adapted to a clamping station formed by each clamping unit 133 in the first clamping group 131 and the second clamping group 132, so as to avoid excessive paint accumulation on the substrate 11 during the spraying operation; in a preferred embodiment, the substrate 11 is also provided with a second cavity 112, so as to further reduce the weight of the substrate and save materials.

[0080] In some preferred embodiments, the clamp device further comprises a rotation positioning sensor 16, which is coaxially arranged with the driven wheel 1224 and is used to determine the rotation angle of the clamped lure 9.

[0081] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications may be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
