[0032] Please see Figure 1 and Figure 2 This utility model provides a variable-pitch positioning device 100. The variable-pitch positioning device 100 includes a feeding module 30, a temporary storage module 50, and a variable-pitch module 70. The feeding module 30 includes a feeding drive mechanism 32 and a gripping mechanism 34. The gripping mechanism 34 includes a gripping drive mechanism 341 and N gripping elements 343 arranged along a first direction. The gripping drive mechanism 341 is mounted on the feeding drive mechanism 32, and the gripping elements 343 are mounted on the gripping drive mechanism 341. The temporary storage module 50 includes M temporary storage seats 54 arranged along the first direction, where N and M are both natural numbers greater than 1, and N is greater than M. The variable-pitch module 70 includes a variable-pitch drive mechanism 72 and M adjusting seats 74 arranged along the first direction. The variable-pitch drive mechanism 72 is connected to the adjusting seats 74.

[0033] The gripping drive mechanism 341 drives the gripping members 343 to move along a third direction, so that N gripping members 343 respectively grip N materials 201 arranged along a first direction on the first material tray 200. The loading drive mechanism 32 drives the gripping mechanism 34 with N materials 201 to move along a second direction to the temporary storage seat 54. The gripping drive mechanism 341 is also used to drive NM gripping members 343 to release NM materials 201 onto NM temporary storage seats 54. The loading drive mechanism 32 is also used to drive the gripping mechanism 34 with the remaining M materials 201 to move along the second direction to the adjusting seat 74. The gripping drive mechanism 341 is also used to drive the remaining M gripping members 343 to release M materials 201 onto M adjusting seats 74. The pitch-changing drive mechanism 72 drives the M adjusting seats 74 to move to adjust the distance between two adjacent adjusting seats 74.

[0034] In the aforementioned variable-distance positioning device 100, the feeding module 30 can place N materials 201 arranged along the first direction into NM temporary storage seats 54 and M adjustment seats 74 respectively, thereby realizing the conversion of materials 201 with different placement layouts, reducing manual labor intensity, and simplifying the operation process.

[0035] Specifically, the variable distance positioning device 100 is a device that enables the material 201 on the production line to switch between different combinations and distance conversions, so that the material 201 can adapt to the needs of different sized trays 200.

[0036] In related technologies, the production process of electronic devices such as mobile phones often involves stages such as material transfer, packaging material rewinding, and automatic film peeling. The material transfer stage handles the flow of components between different production lines; the packaging material rewinding stage is responsible for transferring biological and cooked materials between different sized packaging containers; and the automatic film peeling stage is responsible for peeling the protective film off precision components such as the back panel and screen of the casing. All three stages involve tray transfer operations for electronic device casings. Especially in the automatic film peeling stage for mobile phone casings, it is necessary to convert 10 pieces (2×5 trays) into 4 pieces (1×4 trays), allowing the existing automatic film peeling machine to continue to be used without manual film peeling by operators.

[0037] However, the current method of combining distance conversion relies heavily on manual operation. Operators need to move 2×5-sized trays filled with shells to the rewinding station, manually grab the shells and adjust their placement angle, and finally load them into 1×4-sized dedicated trays. This manual operation leads to a significant increase in labor intensity, is cumbersome, and results in low production efficiency.

[0038] In this embodiment of the utility model, please refer to Figure 1The second direction, the first direction, and the third direction are perpendicular to each other. The first direction includes the Y+ and Y- directions, the second direction includes the X+ and X- directions, and the third direction includes the Z+ and Z- directions. The variable pitch positioning device 100 includes a support module 10, a feeding module 30, a temporary storage module 50, and a variable pitch module 70. The feeding module 30, the temporary storage module 50, and the variable pitch module 70 are all integrated on the support module 10, which makes the overall structure compact and simple. The feeding module 30 includes a feeding drive mechanism 32 and a gripping mechanism 34. The gripping mechanism 34 can be disposed on the feeding drive mechanism 32, so that the feeding drive mechanism 32 can drive the gripping mechanism 34 to move along the second direction to move back and forth between the material tray 200, the temporary storage module 50, and the variable pitch module 70, thereby performing a combined variable pitch operation.

[0039] Optionally, in one embodiment, the feeding drive mechanism 32 includes a linear motor 321, a first slide rail 323 and a first slider 325. The first slider 325 has a groove on the side facing the first slide rail 323 that matches the shape of the first slide rail 323, so that the first slider 325 can move relative to the first slide rail 323 along the length direction of the first slide rail 323, thereby driving the gripping mechanism 34 to move in the second direction.

[0040] Optionally, the loading drive mechanism 32 also includes a cable chain 327, which is used to wrap cables or hoses that will move with the movable block, preventing them from rubbing against other equipment and causing wear. The cable chain 327 is connected to the movable block so that the movable block can drive the cable chain 327 to move together in the second direction.

[0041] Combined pitch control operation is as follows: Please combine Figures 1 to 4 The gripping mechanism 34 includes a gripping drive mechanism 341 and N gripping elements 343 arranged along a first direction. The gripping drive mechanism 341 is mounted on the feeding drive mechanism 32, and the N gripping elements 343 are mounted on the gripping drive mechanism 341. The feeding drive mechanism 32 can drive the gripping drive mechanism 341 to move, thereby causing the gripping elements 343 to move along a second direction. When moving to the material tray 200, the gripping drive mechanism 341 can drive the gripping elements 343 to move along a third direction to grip the N materials 201 on the material tray 200. Optionally, the gripping drive mechanism 341 can be a cylinder.

[0042] Please combine Figure 2 and Figure 5 The temporary storage module 50 includes M temporary storage seats 54 arranged along the first direction. Since the variable pitch module 70 processes only M materials 201 at a time, a temporary storage device is set up to temporarily store the excess NM materials 201, thereby enabling the N materials 201 to be converted into M materials 201 at a fixed pitch, realizing the change in the quantity of materials 201.

[0043] Please combine Figure 2 , Figure 6 and Figure 7 The variable pitch module 70 includes a variable pitch drive mechanism 72 and M adjustment seats 74 arranged along a first direction. The variable pitch drive mechanism 72 is connected to the adjustment seats 74. The feeding drive mechanism 32 drives the gripping mechanism 34 carrying the remaining M materials 201 to move along a second direction to the adjustment seats 74. The gripping drive mechanism 341 drives the remaining M gripping members 343 to release the M materials 201 to the M adjustment seats 74. Then, the variable pitch drive mechanism 72 can drive the gripping members 343 to move along the first direction to adjust the distance between the two adjustment seats 74, thereby adjusting the distance between the M materials 201 to adapt to the material tray 200 specifications required by the subsequent process, realizing the variable pitch conversion from a combination of N materials 201 arranged along the first direction to a combination of M materials 201. Optionally, N and M are both natural numbers greater than 1, and N is greater than M. The specific values ​​of N and M can be specifically limited according to the actual situation, and this utility model does not make a specific limitation in this regard.

[0044] It is understood that in other embodiments, the variable pitch positioning device 100 can also realize the variable pitch conversion from a combination of M materials 201 arranged along the first direction to a combination of N materials 201.

[0045] Therefore, through the coordinated work of the feeding module 30, the temporary storage module 50 and the variable pitch module 70, the conversion of materials 201 with different placement layouts can be achieved efficiently, reducing the intensity of manual labor and simplifying the operation process.

[0046] In one example, please combine Figure 1 The material tray 200 has a specification of 2×5, N is 5, M is 4, that is, the gripping mechanism 34 includes 5 gripping parts 343 arranged along the first direction, the temporary storage module 50 includes 4 temporary storage seats 54 arranged along the first direction, and the variable pitch module 70 includes 4 adjustment seats 74 arranged along the first direction.

[0047] During the operation of the variable-pitch positioning device 100, the feeding drive mechanism 32 first drives the gripping mechanism 34 to move along the second direction to the material tray 200. The gripping drive mechanism 341 then drives five gripping elements 343 to move along the third direction, so that each of the five gripping elements 343 grips a corresponding material 201. Next, the feeding drive mechanism 32 drives the gripping mechanism 34 carrying the five materials 201 to move along the second direction to the temporary storage seat 54. The gripping drive mechanism 341 then drives one of the gripping elements 343 to release the corresponding material 201 onto one of the temporary storage seats 54. Finally, the feeding drive mechanism 32 drives the gripping mechanism 34 carrying the remaining four materials 201 to move along the second direction to the adjustment seat 74. The gripping drive mechanism 341 then drives the remaining four gripping elements 343 to release the corresponding four materials 201 onto the four adjustment seats 74. The variable pitch drive mechanism 72 can drive four adjusting seats 74 to move along a first direction to adjust the distance between two adjacent adjusting seats 74, thereby adjusting the distance of the materials 201 on the four adjusting seats 74 to adapt to the specifications of the material trays 200 required by subsequent processes. Therefore, it is possible to realize the variable pitch conversion from a 2×5 material 201 combination to a 1×4 material 201 combination.

[0048] It is understandable that after the distance adjustment is completed, the material 201 can be manually or automatically unloaded and transferred to the next section for further processing.

[0049] In some embodiments, the N gripping elements 343 include NM first gripping elements 343a and M second gripping elements 343b, and the gripping drive mechanism 341 includes a first gripping drive mechanism 341a and a second gripping drive mechanism 341a. The first gripping drive mechanism 341a is connected to the first gripping elements 343a and is used to drive the first gripping elements 343a to move along a third direction to grip and release NM materials 201. The second gripping drive mechanism 341b is connected to the second gripping elements 343b and is used to drive the second gripping elements 343b to move along a third direction to grip and release M materials 201.

[0050] Thus, through the coordinated operation between the first gripper 343a and the second gripper 343b, the material 201 can be released at different positions.

[0051] Specifically, please combine Figure 1 and Figure 2In one embodiment, when the feeding drive mechanism 32 drives the gripping mechanism 34 to move along the second direction to the material tray 200, the first gripping drive mechanism 341a drives NM first gripping members 343a to move along the third direction to grip NM materials 201, and the second gripping drive mechanism 341b drives M second gripping members 343b to move along the third direction to grip M materials 201, so that the first gripping members 343a and the second gripping members 343b jointly grip N materials 201.

[0052] When the feeding drive mechanism 32 drives the gripping mechanism 34 carrying N materials 201 to move along the second direction to the temporary storage seat 54, the first drive mechanism drives NM first gripping members 343a to move along the third direction to release NM materials 201 to the NM temporary storage seats 54. When the feeding drive mechanism 32 drives the gripping mechanism 34 carrying the remaining M materials 201 to move along the second direction to the adjustment seat 74, the second gripping drive mechanism 341b drives M second gripping members 343b to move along the third direction to release M materials 201 to the M adjustment seats 74.

[0053] Optionally, the first gripping drive mechanism 341a and the second gripping drive mechanism 341b may be cylinders.

[0054] The number of the first gripper 343a and the second gripper 343b can be specifically limited according to the actual situation, and this utility model does not make a specific limitation in this regard. In a comprehensive test, the number of the first gripper 343a is 1, and the number of the second gripper 343b is 4.

[0055] In some embodiments, the second gripper 343b is provided with a plurality of adjustment holes 343c arranged along the first direction, and the second gripping drive mechanism 341b is connected to the M second grippers 343b through the first connector 347. The variable pitch positioning device 100 also includes a fastener (not shown), which passes through the first connector 347 and is connected to the hole wall of a corresponding adjustment hole 343c.

[0056] In this way, the distance between the second gripper 343b can be adjusted.

[0057] Specifically, please combine Figure 4The second gripping drive mechanism 341b is connected to M second gripping members 343b via a first connector 347. The second gripping drive mechanism 341b can drive the first connector 347 to move, thereby moving the M second gripping members 343b along a third direction. Optionally, the first connector 347 is provided with a mating hole 347a. When it is necessary to adjust the distance between the second gripping members 343b, an adjustment hole 343c at a suitable position on the second gripping member 343b and a corresponding mating hole 347a on the first connector 347 can be selected according to the required distance. The adjustment hole 343c is aligned with the mating hole 347a, and a fastener passes through the mating hole 347a and connects with the corresponding adjustment hole 343c. The fasteners include, but are not limited to, screws, bolts, and pins.

[0058] Optionally, the fitting hole 347a can be gourd-shaped or round.

[0059] The number and position of the adjustment hole 343c and the mating hole 347a can be specifically limited according to the actual situation, and this utility model does not make specific limitations in this regard.

[0060] In some embodiments, the gripper 343 includes a suction cup 346 for sucking up and releasing material 201.

[0061] This prevents damage to the surface of material 201.

[0062] Specifically, please combine Figure 2 and Figure 3 The gripper 343 includes a second fixing member 345 and a suction cup 346. The suction cup 346 is located on the side of the second fixing member 345 facing the material 201 for sucking up and releasing the material 201. Since the material in contact with the surface of the material 201 by the suction cup 346 can be flexible silicone, it can prevent the transmission mechanical grippers from leaving scratches, indentations, or other damage on the surface of the material 201 by squeezing or clamping it. The number of suction cups 346 can be specifically limited according to the actual situation, and this utility model does not make a specific limitation in this regard. In one example, one second fixing member 345 is provided with three suction cups 346.

[0063] Optionally, the variable-pitch positioning device 100 also includes a vacuum generator (not shown), which can be connected to the suction cup 346. The vacuum generator uses compressed air to generate negative pressure, thereby providing suction power for the suction cup 346. When the gripper 343 grips the material 201, the vacuum generator pumps air to create a negative pressure inside the suction cup 346. The suction cup 346 deforms and adheres to the surface of the material 201, expelling internal air to form a seal, thus allowing the suction cup 346 to pick up the material 201. When the gripper 343 releases the material 201, the vacuum generator stops pumping air, causing the negative pressure to gradually decrease, thereby causing the suction cup 346 to detach from the material 201 and release the material 201.

[0064] In some embodiments, the temporary storage module 50 includes a temporary storage drive mechanism 52, which is connected to a temporary storage seat 54. The temporary storage drive mechanism 52 is used to drive M temporary storage seats 54 to move along a first direction so that NM temporary storage seats 54 correspond one-to-one with the NM materials 201 to be released in a third direction.

[0065] In this way, the continuity of the process of the gripper 343 releasing material 201 to the temporary storage seat 54 is guaranteed to a certain extent.

[0066] Specifically, please combine Figure 2 and Figure 5 The temporary storage drive mechanism 52 includes a first drive member 521, a support arm 523, and a third fixing member 525. The third fixing member 525 is connected to the first drive member 521 through the support arm 523. M temporary storage seats 54 are spaced apart on the third fixing member 525. When the feeding drive mechanism 32 drives the gripping mechanism 34 carrying N materials 201 to move along the second direction to the temporary storage seat 54, the first drive member 521 can drive the support arm 523 to move, thereby driving the third fixing member 525 to move along the first direction, thereby driving the M temporary storage seats 54 to move along the first direction, so that the NM temporary storage seats 54 correspond one-to-one with the NM materials 201 to be released in the third direction. The gripping drive mechanism 341 drives the gripping member 343 to move along the third direction to release the NM materials 201 to the NM temporary storage seats 54. Therefore, since NM materials 201 are all released from a specific direction, and the temporary storage seat 54 moves back and forth along the first direction under the drive of the temporary storage drive mechanism 52, the NM temporary storage seats 54 can reach the corresponding positions in sequence to receive the materials 201, which can reduce the position adjustment time of the temporary storage seat 54, and to a certain extent ensure the continuity of the above process, thereby improving production efficiency.

[0067] Optionally, the first drive element 521 may be a cylinder.

[0068] In some embodiments, the feeding drive mechanism 32 is further configured to drive the gripping mechanism 34 to move along the second direction to the temporary storage seats 54 when all M temporary storage seats 54 are filled with materials 201. The gripping drive mechanism 341 is further configured to drive the M gripping members 343 to grip the M materials 201 on the M temporary storage seats 54 respectively. The feeding drive mechanism 32 is further configured to drive the gripping mechanism 34 carrying the M materials 201 to move along the second direction to the adjusting seat 74. The gripping drive mechanism 341 is further configured to drive the M gripping members 343 to release the M materials 201 onto the M adjusting seats 74 respectively.

[0069] This ensures the continuity of the entire combined pitch change process while avoiding material waste.

[0070] Specifically, if redundant material 201 remains in the temporary storage seat 54, as the gripping mechanism 34 continuously grips new material 201, the M temporary storage seats 54 will become full and unable to receive newly gripped material 201, causing the gripping mechanism 34 to stop working. Therefore, transferring the M material 201 to the adjusting seat 74 when all M temporary storage seats 54 are filled with material 201 can free up space for subsequent gripping of material 201 to the temporary storage seats 54, ensuring the continuity of the entire combined pitch change process. At the same time, it can also combine all material 201 for pitch change to a certain extent, avoiding waste of material 201.

[0071] In one embodiment, after the gripping drive mechanism 341 performs M combined pitch-changing operations, all M temporary storage seats 54 are filled with materials 201. The loading drive mechanism 32 drives the gripping mechanism 34 to move along the second direction to the temporary storage seats 54. The gripping drive mechanism 341 drives the M gripping elements 343 to grip the M materials 201 on the M temporary storage seats 54 respectively. Then, the loading drive mechanism 32 drives the gripping mechanism 34 with the M materials 201 to move along the second direction to the adjustment seat 74. The gripping drive mechanism 341 drives the M gripping elements 343 to release the M materials 201 to the M adjustment seats 74 respectively. The pitch-changing drive mechanism 72 drives the M adjustment seats 74 to move to adjust the distance between two adjacent adjustment seats 74, thereby adapting to the specifications of the material tray 200 required by the subsequent process.

[0072] In some embodiments, the pitch module 70 includes a first fixing member 75, a second connecting member 76, and a first adjusting member 78. The pitch drive mechanism 72 is connected to the adjusting seat 74 via the second connecting member 76. The first adjusting member 78 is threadedly connected to the second connecting member 76 and abuts against the first fixing member 75. The first adjusting member 78 is used to adjust the position of the second connecting member 76 relative to the first fixing member 75 during rotation, thereby adjusting the distance between two adjacent adjusting seats 74.

[0073] This ensures that the distance between the adjusting seats 74 is consistent with the distance between the gripping members 343, so that the M materials 201 gripped by the gripping members 343 can be accurately placed in the adjusting seats 74.

[0074] Specifically, please combine Figure 6The first adjusting member 78 passes through and is threadedly connected to the second connecting member 76. Based on the principle of threaded transmission, the rotational movement of the first adjusting member 78 is converted into the linear movement of the second connecting member 76 along the axis of the first adjusting member 78. That is, when the first adjusting member 78 rotates, it can drive the second connecting member 76 to move relative to the first adjusting member 78 in a first direction. Moreover, one end of the first adjusting member 78 is always in contact with the first fixing member 75. When the first adjusting member 78 rotates, it can adjust the position of the second connecting member 76 relative to the first fixing member 75, thereby adjusting the distance between two adjacent adjusting seats 74. This ensures that the distance between the adjusting seats 74 is consistent with the distance between the gripping members 343, so that the M materials 201 gripped by the gripping members 343 can be accurately placed in the adjusting seats 74, making the operation simple.

[0075] Optionally, the first adjusting element 78 may be a screw.

[0076] The variable pitch drive mechanism 72 is connected to the adjusting seat 74 via the second connector 76. When material 201 is placed on the adjusting seat 74, the variable pitch drive mechanism 72 can move the second connector 76 to move the adjusting seat 74 along a first direction, thereby adjusting the distance between two adjacent adjusting seats 74 to accommodate the material tray 200 required in subsequent processes. Optionally, one adjusting seat 74 is connected to one second connector 76.

[0077] In some embodiments, the pitch drive mechanism 72 includes a first pitch drive mechanism 72a, which is connected to a second connector 76 and is used to drive the second connector 76 to move the adjusting seat 74.

[0078] In this way, the distance between two adjacent adjustment seats 74 can be adjusted to fit the material tray 200 specification required for subsequent processes.

[0079] Specifically, please combine Figure 7 The first variable-pitch drive mechanism 72a also includes a second drive member 721, a second slide rail 723, and a second slider 725. The second slider 725 has a groove on the side facing the second slide rail 723 that matches the shape of the second slide rail 723, so that the second slider 725 can move relative to the second slide rail 723 along the length direction of the second slide rail 723. The second slide rail 723 is located on the side of the first fixing member 75 away from the adjusting seat 74. The second drive member 721 is connected to the second connecting member 76 through the second slider 725, so that the second drive member 721 can drive the second slider 725 to move, thereby driving the second connecting member 76 to move along the first direction, and driving the adjusting seat 74 to move along the first direction to adjust the distance between two adjacent adjusting seats 74, adapting to the material tray 200 specification required by the subsequent process.

[0080] Optionally, the second driving element 721 can be a pen-shaped cylinder. The number of first variable-pitch driving mechanisms 72a can be specifically limited according to actual conditions, and this utility model does not make a specific limitation in this regard. In one example, please refer to... Figure 7 The number of the first variable pitch drive mechanism 72a is 2.

[0081] In some embodiments, the pitch module 70 includes a first fixing member 75, a third connecting member 77, and a second adjusting member 79. The pitch driving mechanism 72 is connected to the adjusting seat 74 through the third connecting member 77. The second adjusting member 79 is connected to the first fixing member 75. The second adjusting member 79 is clamped between two third connecting members 77 connected to two adjacent adjusting seats 74. The size of the second adjusting member 79 can adjust the distance between the two third connecting members 77 connected to the two adjacent adjusting seats 74, thereby adjusting the distance between the two adjacent adjusting seats 74.

[0082] This ensures that the distance between the adjusting seats 74 is consistent with the distance between the gripping members 343, so that the M materials 201 gripped by the gripping members 343 can be accurately placed in the adjusting seats 74.

[0083] Specifically, please combine Figure 2 and Figure 6 Each pair of adjacent adjusting seats 74 is connected to a corresponding third connecting member 77. When adjusting the distance between the two adjacent adjusting seats 74, the second adjusting member 79 is placed on the first fixing member 75, and the second adjusting member 79 is clamped between the two third connecting members 77 connected to the two adjacent adjusting seats 74. By replacing the second adjusting member 79 with a different size, that is, adjusting the length of the second adjusting member 79 parallel to the first direction, the distance between the two adjacent third connecting members 77 can be changed, thereby adjusting the distance between the two adjacent adjusting seats 74, so that the distance between the adjusting seats 74 is consistent with the distance between the gripping members 343, so that the M materials 201 gripped by the gripping members 343 can be accurately placed in the adjusting seats 74, which is simple to operate.

[0084] The size of the second adjustment member 79 can be specifically limited according to the actual situation, but this utility model does not make a specific limitation in this regard.

[0085] The variable pitch drive mechanism 72 is connected to the adjusting seat 74 via a third connector 77. When material 201 is placed on the adjusting seat 74, the variable pitch drive mechanism 72 can move the adjusting seat 74 along a first direction by driving the third connector 77 to adjust the distance between two adjacent adjusting seats 74 to accommodate the material tray 200 required in subsequent processes. Optionally, one adjusting seat 74 is connected to one third connector 77.

[0086] In some embodiments, the pitch drive mechanism 72 includes a second pitch drive mechanism 72b, which is connected to a third connector 77 and is used to drive the third connector 77 to move the adjusting seat 74.

[0087] In this way, the distance between two adjacent adjustment seats 74 can be adjusted to fit the material tray 200 specification required for subsequent processes.

[0088] Specifically, please combine Figure 7 The second pitch drive mechanism 72b can be connected to the adjustment seat 74 via the third connector 77. Thus, the second pitch drive mechanism 72b can drive the adjustment seat 74 to move along the first direction by driving the third connector 77 to move. This allows the distance between two adjacent adjustment seats 74 to be adjusted to fit the material tray 200 specification required by the subsequent process.

[0089] Optionally, the second pitch drive mechanism 72b may include a cylinder.

[0090] In some embodiments, both the temporary storage seat 54 and the adjustment seat 74 include a positioning module 90, which is used to position the material 201.

[0091] This reduces the adjustment time caused by improper positioning of material 201.

[0092] Specifically, taking the adjustment seat 74 as an example, in Figure 8 In this embodiment, the positioning module 90 includes a base 92 and support columns 94. Both the base 92 and the adjusting seat 74 include an adapter plate 20, with the base 92 positioned above and fixedly connected to the adapter plate 20. Multiple support columns 94 are disposed on the base 92, providing multiple support points for the material 201, which can reduce the contact area between the material 201 and the positioning module 90 to a certain extent, facilitating the gripping of the material 201. Optionally, the support columns 94 are positioned on the base 92 at locations corresponding to and avoiding the sandblasted, easily damaged parts of the material 201, reducing the risk of the material 201 being bumped or scratched. The number of support columns 94 can be specifically limited according to actual conditions; this utility model does not impose a specific limitation in this regard. In one example, please refer to... Figure 8 There are 4 support columns (94).

[0093] The positioning module 90 also includes a guide member 96. The shape and size of the guide member 96 are adapted to the shape and size of the through hole opened in the material 201 itself. The guide member 96 is used to pass through the material 201 to guide the direction of the material 201 placement base 92 and adjusting seat 74 and to determine the position of the material 201. The number and shape of the guide members 96 can be specifically limited according to the actual situation, and this utility model does not make a specific limitation in this regard. In one example, please refer to... Figure 8The guide member 96 includes a first guide member 961 and a second guide member 963. The first guide member 961 is cyclone-shaped and is used to pass through the circular through hole corresponding to the material 201. The second guide member 963 is square-pyramidal and is used to pass through the rectangular through hole corresponding to the material 201. Therefore, through the cooperation between the first guide member 961, the second guide member 963 and the material 201, the accurate position of the material 201 on the temporary storage seat 54 and the adjustment seat 74 can be determined, thereby reducing the adjustment time caused by improper positioning of the material 201 and thus improving the overall production efficiency to a certain extent.

[0094] In some embodiments, the temporary storage base 54 is provided with a first sensor 41, which outputs a first signal when the material 201 is not placed on the temporary storage base 54, outputs a second signal when a single material 201 is placed on the temporary storage base 54, and outputs a third signal when stacked materials 201 are placed on the temporary storage base 54.

[0095] The adjustment seat 74 is provided with a second sensor 43, which is used to output a fourth signal when the material 201 is not placed on the adjustment seat 74, output a fifth signal when a single material 201 is placed on the adjustment seat 74, and output a sixth signal when stacked materials 201 are placed on the adjustment seat 74.

[0096] This can be used to prevent situations where no material 201 is placed or where material 201 is stacked during the process of the gripper 343 releasing material 201 to the temporary storage seat 54 and the adjustment seat 74.

[0097] Specifically, please combine Figure 5 , Figure 6 and Figure 8 The first sensor 41 and the second sensor 43 are each disposed on the base 92 of the positioning module 90 corresponding to the temporary storage seat 54 and the adjustment seat 74. When the material 201 is placed on the temporary storage seat 54 or the adjustment seat 74, the material 201 is supported by the support column 94 and spaced apart from the sensor 40. In some embodiments, the first sensor 41 can detect whether the temporary storage seat 54 and the adjustment seat 74 have material 201 placed on them and whether there is a stack of material 201 based on the eddy current effect, thereby outputting a corresponding signal. The variable pitch positioning device 100 can perform corresponding operations according to the output signal. Optionally, the sensor 40 includes, but is not limited to, an inductive proximity switch, an eddy current sensor, etc.

[0098] Optionally, both the first sensor 41 and the second sensor 43 are equipped with coils, which generate an alternating electromagnetic field when energized. Please refer to... Figure 5The temporary storage seat 54 is equipped with a first sensor 41. In one embodiment, when the gripper 343 releases material 201 into the temporary storage seat 54, if no material 201 is placed on the temporary storage seat 54, the electromagnetic field is uniformly distributed and the coil inductance is stable, and the first sensor 41 can output a first signal. The variable-pitch positioning device 100 can issue a prompt based on the first signal, such as issuing a prompt signal including but not limited to sound or light, or sending the prompt signal to the display screen of the variable-pitch positioning device 100 for display, thereby promptly reminding the operator that there is no material 201 placed on the temporary storage seat 54, so that the operator can perform timely maintenance on the device.

[0099] In one embodiment, when the gripper 343 releases material 201 to the temporary storage seat 54, if a single piece of material 201 is placed on the temporary storage seat 54, the material 201 enters the electromagnetic field, and the conductivity or permeability of the material 201 changes the distribution of the electromagnetic field, generating eddy currents, consuming electromagnetic field energy, resulting in a decrease in coil inductance and an increase in impedance. The first sensor 41 can then output a second signal. The variable-pitch positioning device 100 can perform a next operation based on the second signal, including but not limited to controlling the feeding drive mechanism 32 to drive the gripper mechanism 34 to move along the second direction to the adjustment seat 74, etc.

[0100] In one embodiment, when the gripper 343 releases material 201 to the temporary storage seat 54, if there is a stack of material 201 on the temporary storage seat 54, the increased thickness of the material 201 will enhance the eddy current effect, and the first sensor 41 can output a third signal. The variable-pitch positioning device 100 can issue a prompt based on the third signal, thereby promptly reminding the operator that there is a stack of material 201 on the temporary storage seat 54, so that the operator can perform timely maintenance on the device.

[0101] Please combine Figure 6 and Figure 8 The adjusting seat 74 is equipped with a second sensor 43. In one embodiment, when the gripper 343 releases material 201 onto the adjusting seat 74, if no material 201 is placed on the adjusting seat 74, the electromagnetic field is uniformly distributed and the coil inductance is stable, and the second sensor 43 can output a fourth signal. The variable-pitch positioning device 100 can issue a prompt based on the fourth signal, such as issuing a prompt signal including but not limited to sound or light, or sending the prompt signal to the display screen of the variable-pitch positioning device 100 for display, thereby promptly reminding the operator that there is no material 201 placed on the adjusting seat 74, and thus the operator can promptly inspect and maintain the device.

[0102] In one embodiment, when the gripper 343 releases material 201 onto the adjusting seat 74, if a single piece of material 201 is placed on the adjusting seat 74, the material 201 enters the electromagnetic field, and its conductivity or permeability alters the distribution of the electromagnetic field, generating eddy currents and consuming electromagnetic field energy. This results in a decrease in coil inductance and an increase in impedance, and the second sensor 43 can output a fifth signal. The variable pitch positioning device 100 can then perform a next operation based on the fifth signal, including but not limited to controlling the variable pitch drive mechanism 72 to drive the adjusting seat 74 to move and adjust the distance between two adjacent adjusting seats 74.

[0103] In one embodiment, when the gripper 343 releases material 201 onto the adjusting seat 74, if there is a stack of material 201 on the adjusting seat 74, the increased thickness of the material 201 will enhance the eddy current effect, and the second sensor 43 can output a sixth signal. The variable-pitch positioning device 100 can issue a prompt based on the sixth signal, thereby promptly reminding the operator that there is a stack of material 201 on the adjusting seat 74, and allowing the operator to perform timely maintenance on the device.

[0104] The number of the first sensor 41 and the second sensor 43 can be specifically limited according to the actual situation, and this utility model does not make a specific limitation in this regard. In one example, a first sensor 41 is provided on a temporary storage seat 54, and a second sensor 43 is provided on an adjustment seat 74.
