The closed loop transmission device 2 includes a plurality of carrying portions 201 for circulating transmission, each carrying portion 201 is provided with a set of carrier 3, the carrier 3 can be formed by processing cold plates, stainless steel plates or other steel materials and used for carrying sheet bodies (not shown), wherein the sheet bodies can be various sheet-shaped parts known to those skilled in the art, such as conductive sheets on switches, tabs of batteries, and elastic sheets on OIS (optical isolator) driving motors.

The first transmission portion 21 includes a first guiding portion 211 and a first driving portion 212, and the first driving portion 212 can be connected to the carrying portion 201, such as connected to the carrying portion 201 through the carrier 3.

Likewise, the second transmission part 23 includes a second guide part 231 and a second driving part 232, the second driving part 232 may be connected with the carrying part 201, and the carrying part 201 may slide on the second guide part 231.

Here, since the configuration of the first transfer unit 21 and the configuration of the second transfer unit 23 may be the same, the first transfer unit 21 is selected and described.

The first guiding portion 211 may include a first linear sliding rail 211a, and the bearing portion 201 may be a slider 211b sliding on the first linear sliding rail 211 a. Of course, the first guide portion 211 may be a combination of at least two linear guide shafts, and the carrier portion 201 includes at least two linear bearings, each of which slides on the linear guide shaft.

The carrier 3 is provided with a hanging part 301, and the rotating mechanism 252 can drive the rotating member 251 to rotate, so that the plurality of traction members 253 are respectively hooked on the hanging part 301 or separated from the hanging part 301. Specifically, the pulling member 253 may be a bar, and the hanging portion 301 of the carrier 3 may be a notch formed in the carrier 3, and when the rotating mechanism 252 rotates, the bar may be locked to or separated from the notch.

The first driving part 212 further includes a stepping part 26, and the drawing part 25 is connected to the stepping part 26, wherein the stepping part 26 includes a motor-driven single-axis robot, and thus the drawing part 25 is mounted on the single-axis robot, and a driving direction of the single-axis robot is parallel to a guiding direction of the first guiding part 211. The plurality of carriers 201 and the carriers 3 are preferably distributed at the same distance, which is a distance between working areas of respective stations of the process treatment section 4 described below. When the rotating mechanism 252 rotates to clamp the long block to the notch, the stepping portion 26 travels a distance, that is, the single-axis robot drives the drawing portion 25 to travel a distance, so as to pull the carrying portion 201 to slide on the first guide portion 211, and transfer from a previous station to a next station of the process processing portion 4, for example, from a sheet feeding portion 5 (described below) to a sheet punching portion 6 (described below) of the process processing portion 4. Alternatively, one of the carrier parts 201 of the second relay section 24 is pulled from the second relay section 24 to the first transfer section 21, and the other carrier part 201 of the first transfer section 21 is pulled from the first transfer section 21 to the first relay section 22.

The first rotation part 22 includes a third guide part 221 and a third driving part 222, and similarly, the third guide part 221 may include a second linear slide rail 221a, and the third driving part 222 is preferably an air cylinder, such as a rodless air cylinder 222 a. The third guide part 221 is provided with a first relay guide part 223, the first relay guide part 223 includes a third linear slide rail 223a having the same cross section as the first linear slide rail 211a of the first guide part 211, and the guiding direction of the first relay guide part 223 is the same as the guiding direction of the first guide part 211, that is: the guiding direction of the third linear guide 223a is the same as the guiding direction of the first linear guide 211 a.

The third driving part 222 is connected to the first relay guide 223 and can drive the first relay guide 223 to respectively interface with the first guide 211 and the second guide 231, specifically, the first relay guide 223 further includes a relay slider 223b slidable on the second linear slide rail 221a, the third linear slide rail 223a can be mounted on the relay slider 223b through a relay connection plate 223c, and the rodless cylinder 222a is connected to the relay slider 223b through a relay connection plate 223c and drives the relay slider 223b to slide on the second linear slide rail 221 a.

When the middle slider 223b slides to the first end of the second linear slide rail 221a, the third linear slide rail 223a is butted against the first linear slide rail 211 a. When the middle slider 223b slides to the second end of the second linear guide 221a, the third linear guide 223a is butted against the first linear guide 211a of the second transmission part 23. When the third linear slide rail 223a is docked with the first linear slide rail 211a, the carrying part 201 may drive the drawing part 25 through the stepping part 26, thereby being transferred from the first linear slide rail 211a of the first guide part 211 to the third linear slide rail 223a of the first relay guide part 223 and being slidable on the third linear slide rail 223a of the first relay guide part 223.

Similarly, the structure of the second relay unit 24 may be the same as that of the first relay unit 22, that is, the second relay unit 24 also includes a fourth guide unit 241 and a fourth driving unit 242, the fourth guide unit 241 is provided with a second relay guide unit 243, the guide direction of the second relay guide unit 243 is the same as that of the first guide unit 211, the fourth driving unit 242 is connected with the second relay guide unit 243, the second relay guide unit 243 is respectively abutted with the second guide unit 231 and the first guide unit 211, and similarly, the carrying unit 201 may slide on the second relay guide unit 243 to be transferred from the second transfer unit 23 to the second relay guide unit 243 or from the second relay guide unit 243 to the first transfer unit 21.

When the bearing part 201 is a slider 211b that can slide on the first linear guide 211a or the third linear guide 223a, respectively, since a plurality of balls are usually provided on the slider 211b to improve the smoothness of the slider on the linear guide, the balls may be chain-shaped or non-chain-shaped. In order to prevent the balls from falling off when the bearing part 201 is transferred and transmitted between the guide parts, the distance between the opposite end surfaces of the guide parts is preferably less than 0.5mm when the guide parts are butted, and is between 0mm and 0.5mm, the smaller the distance is, the better the distance is.

That is, when the third guide portion 221 and the first guide portion 211 are butted, a distance between the facing end surfaces of the third guide portion 221 (the third linear guide rail 223a) and the first guide portion 211 (the first linear guide rail 211a) is less than 0.5 mm. When the third guide portion 221 (the third linear guide rail 223a) and the second guide portion 231 are butted, a distance between the facing end surfaces of the third guide portion 221 (the third linear guide rail 223a) and the second guide portion 231 is less than 0.5 mm. When the fourth guide portion 241 and the first guide portion 211 (the first linear guide 211a) are butted, a distance between the opposite end surfaces of the fourth guide portion 241 and the first guide portion 211 (the first linear guide 211a) is less than 0.5 mm.

Therefore, the process processing parts 4 can be mutually and automatically transmitted through the closed-loop transmission device 2, the working efficiency can be greatly improved, in addition, the closed-loop transmission device 2 is annular, the stations can be compactly arranged, and compared with a sheet body forming line which is linearly arranged or a sheet body production line which is arranged in disorder, the installation space required by the production line is reduced, and the production period for sheet body forming can be shortened.

Since the process treatment units 4 of the different sheet forming lines include different processes, only the basic processes of the sheet forming line, that is, the feeding process, the pressing process, and the blanking process will be described. When different processes need to be added, technical personnel in the field can be correspondingly arranged beside the closed-loop transmission device 2, no matter how many processes are added, the arrangement mode of the process treatment part 4 of the utility model is at least more compact than other arrangement modes to a certain extent, the occupied space is smaller, and the production efficiency is higher.

Referring to fig. 1, the sheet feeding section 5 will be described below as an example.

Lamellar body material loading portion 5 includes: the sheet storage 51, the sheet storage 51 may be plate-shaped, and since the sheet is generally thin in thickness, the sheet storage 51 preferably stores sheets in a stacked manner for further space saving, and the sheet storage 51 may include a plurality of places on each of which a plurality of sheets are stacked.

The sheet feeding part 5 may be provided at the edge of the base 1 to facilitate feeding by an operator, and preferably, the sheet feeding part 5 may be rotationally switched between the edge of the base 1 and a position near the closed-loop transfer device 2 by a rotary cylinder. When the materials need to be supplemented, the rotary cylinder rotates the sheet feeding part 5 to the edge of the base platform 1 from a position close to the closed-loop conveying device 2.

Fig. 4 is a perspective view of the sheet punching part (sheet punching device) of fig. 1; fig. 5 is a perspective view of the carrier of fig. 2; FIG. 6 is a bottom perspective view of the first punch assembly of FIG. 4; fig. 7 is a top perspective view of the second punch assembly of fig. 4. The sheet punching unit 6 (also referred to as a sheet punching device 6) will be described in detail below with reference to fig. 4, 5, 6, and 7.

Since the finished sheet is usually small in size and high in accuracy, the sheet punching portion 6 (i.e., the sheet punching device 6) of the present embodiment includes: the reference positioning portion 303, and the reference positioning portion 303 is provided on the carrier 3. Specifically, the carrier 3 is further provided with a sheet placing portion 302 on which the sheet is placed, on the sheet placing portion 302.

The sheet body punching device 6 further includes: a first punch assembly 62 and a second punch assembly 63, wherein: the first punch assembly 62 is disposed on one side of the carrier 3, and the second punch assembly 63 is disposed on the other side of the carrier 3, opposite to the first punch assembly 62. For example, when the first punching unit 62 and the second punching unit 63 punch the sheet in the up-down direction, the first punching unit 62 is disposed at an upper side of the sheet, and the second punching unit 63 is disposed at a lower side of the sheet. Alternatively, when the first and second punching assemblies 62 and 63 punch the sheet body in the horizontal direction, the first punching assembly 62 may be disposed at the left side of the sheet body, and the second punching assembly 63 may be disposed at the right side of the sheet body.

The first punching member 62 is provided with a first punching positioning portion 621, and the second punching member 63 is provided with a second punching positioning portion 631. Here, the first press positioning portion 621 and the second press positioning portion 631 are positioned and engaged with each other with reference to the reference positioning portion 303. Since the first press positioning portion 621 and the first press positioning portion 621 have the same positioning reference, the pressing accuracy of the sheet body pressing device 6 can be improved.

In addition, the positioning fit herein refers to a fit that can be used as a positioning reference, such as a fit of the pin shaft and the pin hole, a fit of the positioning block and the positioning groove, and a fit between the positioning surface and the positioning surface. For example, the reference positioning portion 303 includes two positioning holes 305 provided on the outer side of the sheet placing portion 302, and the two positioning holes 305 penetrate the carrier 3, respectively, to improve the processing accuracy. In addition, the positioning holes 305 may include three or more than three, if necessary. The first punch positioning portion 621 includes first positioning pins 623, the number of the first positioning pins 623 is the same as the number of the positioning holes 305, such as two, and similarly, the second punch positioning portion 631 includes second positioning pins 633, and the number of the second positioning pins 633 is also the same as the number of the positioning holes 305, such as two.

In order to further improve the positioning fit of the first positioning pin 623 and the second positioning pin 633 with the positioning hole 305, transition fit may be adopted. Here, the transition fitting refers to a fitting manner well known in the mechanical field, for example, the positioning hole 305 is JS7, and the first positioning pin 623 and the second positioning pin 633 are JS6, respectively. In order to prevent the first positioning pin 623 and/or the second positioning pin 633 from being stuck in the positioning hole 305, the first positioning pin 623, the second positioning pin 633, and the positioning hole 305 may be lubricated by lubricating oil or grease.

In addition, as the punching step, the first punching unit 62 is provided with a first punching head 622, and the second punching unit 63 is provided with a second punching head 632. The first punch 622 may be a reference punch (static punch) and the second punch 632 may be a bending punch, a cutting punch, or a shaping punch (dynamic punch). For example, when the sheet body needs to be bent by 90 degrees, the first stamping head 622 firstly attaches to the sheet body, the edge of the first stamping head 622 corresponds to the bent edge of the sheet body, and the second stamping head 632 then stamps the place needing to be bent.

The first punch assembly 62 may include a first mounting plate 625, the first punch 622 may be directly formed on the first mounting plate 625, and the first mounting plate 625 may be provided with a pin hole (not shown) for engaging with the first positioning pin 623.

Similarly, the second punching assembly 63 also includes a second mounting plate 637, and the second punching head 632 may be directly formed during the machining of the second mounting plate 637 or may be directly inserted into the second mounting plate 637 with interference by the second punching head 632. However, since the second punching head 632 needs to be changed in shape according to a specific punching process and the required machining accuracy is very high, both the distance tolerance and the form and position tolerance are required, the second mounting plate 637 is formed together with the second punching head, which causes a sharp increase in cost and also makes it difficult to achieve the machining accuracy. In the case of the interference fit, the form and position tolerance of the fitting position is strict, which also results in a large increase in cost.

Therefore, the second punching head 632 of the present embodiment is locked to the second mounting plate 637, more preferably, by a screw. When the second punch 632 is locked, locking is performed with the first punch 622 as a positioning reference. For example, the press device may further include an auxiliary positioning member 66, the auxiliary positioning member 66 may be provided with an auxiliary reference positioning portion 661 and an auxiliary ram positioning portion 662, the auxiliary reference positioning portion 661 may include an auxiliary positioning hole 661a, during adjustment, the first positioning pin 623 and the second positioning pin 633 are respectively positioned and matched with the auxiliary positioning hole 661a, the auxiliary ram positioning portion 662 is designed to be contoured according to the press shape of the second press head 632, and when the auxiliary reference positioning portion 661 is respectively positioned and matched with the first press positioning portion 621 and the second press positioning portion 631, that is, when the first positioning pin 623 and the second positioning pin 633 are respectively inserted into the auxiliary positioning hole 661a, the second press head 632 is adjusted to fit the second press head 632 with the auxiliary ram positioning portion 662, and then locking is performed.

By setting the second punching head 632 to be adjustable, the processing cost of the second punching head 632 can be greatly reduced, and the risk of processing failure thereof is reduced.
