Background technology

Screen printing apparatus is assembled in the production line of printed circuit board (PCB) (Printed Circuit Board, PCB), the substrate moved is implemented to the printing of conductive paste etc., this substrate is passed out to the element fixing apparatus in downstream from upstream side.This screen printing apparatus mostly as disclosed in Patent Document 1, is generally allow a Printing Department in device receive substrate block by block, and implements printing treatment substrate is passed out to element fixing apparatus.

But, develop the device such as disclosed in patent document 2 in recent years, this device possesses Liang Ge Printing Department arranged side by side and two substrate travelling carriages arranged side by side in the below of this Liang Ge Printing Department, and while allow each Printing Department individually receive substrate from upstream side, printing is implemented to substrate and individually passes out to downstream.This structure is based in a table apparatus to be possessed two substrate carrying lines and utilizes the element fixing apparatus of so-called pair of conveyance type to install be achieved to carry out (walking abreast) element on each carrying line simultaneously, its object is to the efficient activity realizing printing and element is installed by linking these screen printing apparatus and element fixing apparatus.In addition, based on same reason, also developed the device disclosed in patent document 3, this device possesses two carrying lines and a half tone template, two printed patterns corresponding with these carrying lines are formed in this half tone template, this device, while individually receive substrate along each carrying line, utilizes the difference based on carrying line and different printed patterns implements printing, afterwards substrate is individually passed out to element fixing apparatus.

In addition, in order to enhance productivity, the production line of printed circuit board (PCB) is configured with various form.Such as, sometimes require the list conveyance type possessing a substrate carrying line device (being called the device of single system) and possess side by side between the element fixing apparatus of two conveyance types of two substrate carrying lines or two element fixing apparatus (being always called the device of dual system) of single conveyance type screen printing apparatus be set, or on the contrary, screen printing apparatus is set between the upstream side device and the element fixing apparatus of single system of dual system.In addition, even if arrange screen printing apparatus thus when forming two substrate carrying lines from upstream side device to the scope of element fixing apparatus between the upstream side device and the element fixing apparatus of dual system of dual system, sometimes also require, after printing treatment implemented by the substrate moved from upstream side device the substrate carrying line along side, the substrate finished printing to be transported the element fixing apparatus to the substrate carrying line belonging to opposite side.

But, disclosed in patent document 1, device is the device premised between the upstream side device being arranged on single conveyance type and the downstream device (element fixing apparatus) of single conveyance type in the past, and therefore this device cannot directly be employed with its structure individually.On the other hand, for device in the past disclosed in patent document 2,3, because these devices to be arranged between the upstream side device of two conveyance type and the downstream device (element fixing apparatus) of pair conveyance type and substrate carrying line is separately formed in device from upstream side device to the scope of downstream device, therefore cannot directly be employed individually with its structure too.

Therefore, in the utilization of reality, when upstream side is the device of single conveyance type, downstream is device (being assumed to be element fixing apparatus) of two conveyance type, such as, when applying the device of patent document 1 as screen printing apparatus, the distributor of the conveyance destination for distributing substrate can be set between screen printing apparatus and element fixing apparatus.In addition, when applying the device of patent document 2,3 under similar circumstances, can upstream side device with same distributor is set between screen printing apparatus.In addition, on the contrary, when upstream side is the device of two conveyance type, downstream is device (being assumed to be element fixing apparatus) of single conveyance type, when applying the screen printing apparatus of patent document 1 as screen printing apparatus, the switching device shifter in the receiving source for switching substrate can be set between upstream side device and screen printing apparatus, in addition, when applying the device of patent document 2,3 under similar circumstances, can same switching device shifter be set between screen printing apparatus with element fixing apparatus.

In addition, between the upstream side device and the element fixing apparatus of dual system of dual system, screen printing apparatus is set, and when the substrate moved along the substrate carrying line of the side in two substrate carrying lines is transported to the element fixing apparatus of the substrate carrying line belonging to opposite side after printing treatment, on the basis of screen printing apparatus of applying patent document 2,3 as screen printing apparatus, above-mentioned same switching device shifter can be set between screen printing apparatus with element fixing apparatus.

In addition, even if when disclosed in patent document 2,3, screen printing apparatus is arranged between the upstream side device of dual system and the downstream device (element fixing apparatus) of dual system, the spacing moving into the carrying line of the substrate of side due to substrate is identical with the spacing that substrate takes out of the carrying line of the substrate of side, if between the line of therefore each substrate carrying line of upstream side device spacing and each substrate carrying line of element fixing apparatus line between spacing different, then this screen printing apparatus cannot be arranged on separately between upstream side device and element fixing apparatus.Therefore, under these circumstances, the relay transported for interposer can be set up between upstream side device and screen printing apparatus or between screen printing apparatus and element fixing apparatus.

But, if adopt except screen printing apparatus also arranges the production line structure of the auxiliary device of distributor or switching device shifter or relay and so on as described above, unsatisfactory in the space saving realizing printed circuit board fabrication equipment and cost degradation, this point remains the leeway of improvement.

In addition, control group of unifying master computer is equipped with the production line of the printed circuit board (PCB) of printing equipment 1, comprise this printing equipment 1, be assembled in the device (loader L1, L2 and element fixing apparatus M etc.) of this production line all with the mode on-line joining process that can intercom mutually with this master computer, described printing performing a programme and various data are provided to each devices such as this printing equipment 1 from this master computer.

Next, with reference to Figure 11 and Figure 12, the printing action based on the printing equipment 1 of the control of this control device 8 is described.

(a) of Figure 11 is shown schematically in the state of the particular point in time of the printing action carried out continuously in printing equipment 1, specifically, represent the printing of the substrate W supported by second substrate brace table 10B just terminate after state.The state of substrate support pedestal 10A, the 10B of this time point and printing enforcement division 20A, 20B is as follows.

Second substrate brace table 10B is arranged at conveyer belt and accepts position to 12 corresponding with second substrate loading unit En2 second.In this second substrate brace table 10B, grip unit 14 is arranged at printing executing location under the state being clamped with substrate W, and follow-up substrate W substrate position of readiness place is standby.Second printing enforcement division 20B becomes the holding state of specifying that is by shuttering supporting parts 24 being arranged at retreating position thus making template 21 depart from substrate W and scraper plate 42 be arranged at the state of the position of readiness above template one end.

On the other hand, first substrate brace table 10A is arranged at conveyer belt and takes out of described launching position corresponding to portion Ex to 12 with substrate.The substrate W previously printed just is taken out of portion Ex from substrate to take out of to after element fixing apparatus M by this first substrate brace table 10A, and grip unit 14 is in and is arranged at substrate position of readiness and the state being clamped with follow-up substrate W.Herein, the clamping of substrate W is undertaken by operating as follows, that is: after grip unit 14 moves to substrate position of readiness, as shown in Figure 5, by BU platform 150, substrate W is promoted from conveyer belt 12, then by hold assembly described in a pair 160 from Y direction sandwich substrate W.

From the state that (a) of Figure 11 is shown such, first, first substrate brace table 10A accepts position towards second and moves, and namely conveyer belt moves towards the position corresponding with first substrate loading unit En1 12.Now, by the movement of grip unit 14, substrate W is transported to printing executing location from substrate position of readiness, and, in this conveyance midway, by multiple marks of taking with the first described board-recognition camera 50 of printing position corresponding to enforcement division 20A on substrate W, thus image recognition is carried out to the position of the substrate W in grip unit 14.And, multiple marks of the template 21 of the first printing enforcement division 20A are taken by the described board recognition camera 16 being equipped on grip unit 14, thus image recognition is carried out to the relative position of template 21 and grip unit 14, based on these recognition results, the template 21 obtaining printing executing location place offsets with the position of substrate W, and obtain offset corresponding template 21 to this position X-axis, Y-axis and R axle (around Z axis) direction correction value (Δ X, Δ Y, Δ R).Such identifying processing and the computing of correction value are undertaken by the shooting image of above-mentioned control device based on board-recognition camera 50 and board recognition camera 16.

And second substrate brace table 10B is to follow the mode of the movement of this first substrate brace table 10A and to accept position from first and move to launching position.

Thus, as shown in (b) of Figure 11, first substrate brace table 10A is arranged at first and accepts position, and second substrate brace table 10B is arranged at launching position.

When first substrate brace table 10A be arranged at first accept position time, the printing to substrate W is performed by the first printing enforcement division 20A, and, during this period, at first substrate loading unit En1 place, from loader L1 follow-up substrate W received to first substrate brace table 10A and be arranged at substrate position of readiness.Now, the substrate W of printing executing location is being clamped by grip unit 14 by under the state that promotes from conveyer belt 12, therefore can not because of conveyer belt to 12 driving and cause position to offset with the receiving of this subsequent substrate W.

When the first printing printing of enforcement division 20A to substrate W, first, shuttering supporting parts 24 drop to refitting height and position from retreating position, and template 21 is reset in substrate W.Now, by controlling described motor 30,144 based on above-mentioned correction value (Δ X, Δ Y, Δ R), thus revise the relative position of template 21 and substrate W.Specifically, the position correction (correction value Δ X) of the X-direction of substrate W is implemented by the driving of motor 144, implemented position correction (correction value Δ Y) and the axial position correction of R (correction value Δ R) of the Y direction of template 21 by two motors 30, thus template 21 is reset rightly in substrate W.

When the refitting of template 21 couples of substrate W completes, scraper plate 42 is from after retreating position drops to presswork height and position, and squeegee unit 40 entirety comprising scraper plate 42 moves along Y direction, thus implements printing to substrate W.

Like this, during the substrate W of first substrate brace table 10A is printed, in second substrate brace table 10B, remove the clamp position of grip unit 14 couples of substrate W, as shown in (a) of Figure 12, substrate take out of Ex place of portion by printing after substrate W take out of to element fixing apparatus M, and grip unit 14 move to substrate position of readiness to clamp standby in subsequent substrate W.Now, drive conveyer belt to 12 to take out of the substrate W after printing, but at substrate position of readiness place, the subsequent substrate W in standby becomes conveyance halted state by the work of block mechanism 15, thus, the clamping of grip unit 14 to this substrate W becomes possibility.

At the end of the printing of the substrate W on first substrate brace table 10A, the first printing enforcement division 20A is reset as holding state.Namely, by shuttering supporting parts 24 are arranged at retreating position, thus template 21 departs from substrate W, and scraper plate 42 is after template one end of Y direction moving target position of readiness rising is upward mobile, become the state being stopped maintenance, subsequently, first substrate brace table 10A moves to launching position.

On the other hand, second substrate brace table 10B moves to second and accepts position.Now, with the movement of grip unit 14, substrate W is transported to printing executing location from substrate position of readiness, and, in this conveyance midway, by multiple marks of taking with the second board-recognition camera 50 of printing position corresponding to enforcement division 20B on substrate W, and, the mark of the template 21 of the second printing enforcement division 20B is taken by board recognition camera 16, thus, image recognition is carried out to the relative position of template 21 and substrate W, and obtains above-mentioned correction value (Δ X, Δ Y, Δ R) based on these recognition results.

Like this, when such as Figure 12 (b) shown in, first substrate brace table 10A is arranged at launching position, second substrate brace table 10B is arranged at second when accepting position, implement the position correction based on above-mentioned correction value (Δ X, Δ Y, Δ R), template 21 is reset rightly in substrate W, printing is implemented by the second substrate W of printing enforcement division 20B to the printing executing location being arranged at second substrate brace table 10B, and as shown in the drawing, follow-up substrate W is received on this second substrate brace table 10B.On the other hand, for first substrate brace table 10A, remove the clamping of grip unit 14 couples of substrate W, this substrate W after printing is taken out of to the substrate taking out of side end from printing executing location and takes out of portion Ex, then take out of Ex place of portion in substrate and take out of to element fixing apparatus M.

Like this, after, the substrate W moving into first substrate loading unit En1 from loader L1 is received into first substrate brace table 10A, the substrate W moving into second substrate loading unit En2 from loader L2 is received into second substrate brace table 10B, in each printing enforcement division 20A, 20B when the printing of the substrate W that hockets, the substrate W after this printing is taken out of portion Ex from the substrate shared and takes out of to element fixing apparatus M.

As mentioned above, according to this printing equipment 1, utilize the printing process of first substrate brace table 10A (mainly the moving into of past position of readiness of substrate W, clamping substrate, the movement from position of readiness past printing executing location of substrate W, printing, remove substrate clamping, take out of substrate), with utilize the printing process of second substrate brace table 10B (mainly the moving into of past position of readiness of substrate W, clamping substrate, the movement from position of readiness past printing executing location of substrate W, printing, remove substrate clamping, take out of substrate) be implemented concurrently when staggering period, therefore efficiency the printing of substrate W can be carried out well.

And, do not need the auxiliary device such as switching device shifter as the transport path as in the past, printing equipment can be received substrate W from the upstream side device of dual system that is two loaders L1, L2 and implement printing individually, and the element fixing apparatus M of downstream device substrate taken out of to single system that is.Therefore, even if arrange printing equipment 1 between the upstream side device and the downstream device of single system of dual system, also production line can be formed compactly.

And, in this printing equipment 1, as printing enforcement division, possess to the first printing enforcement division 20A printed from the substrate W that loader L1 moves at first substrate loading unit En1 place, with to second substrate loading unit En2 from the substrate W that loader L2 moves into perform print second print enforcement division 20B, therefore, have and can carry out the printing of mutually different pattern to the substrate W sent here respectively from two loaders L1, L2 while substrate to be sent the advantage to element fixing apparatus M.

And, in this printing equipment 1, at each substrate support pedestal 10A, in 10B, grip unit 14 is arranged in the mode being movable to printing executing location and substrate position of readiness, as mentioned above, after printing terminates, remove the clamping of leading substrate W (having implemented the substrate W of printing), taking out of of this substrate W, grip unit 14 move to substrate position of readiness and clamp standby in subsequent substrate W, at substrate support pedestal 10A, from launching position, to accepting position, (first accepts position to 10B, second accepts position) during movement, this substrate W is arranged at printing executing location.That is, after taking out of leading substrate W, be refitted in roughly side by side can perform the period accepting position (first accepts position, second accepts position) with substrate support pedestal 10A, 10B and print enforcement division 20A, the 20B printing to subsequent substrate W.Therefore, after taking out of leading substrate W, the printing of subsequent substrate W can be implemented as soon as possible, thus, for the substrate W sent here respectively from two loaders L1, L2, no matter being when carrying out the printing of same pattern, or when carrying out the printing of mutually different pattern, all having and efficiency can carry out the advantage of the printing of substrate W well.

And, in this printing equipment 1, the conveyer belt variable-width mechanism of substrate support pedestal 10A, 10B as mentioned above as have employed with inside device for benchmark to change conveyer belt to 12 the structure at interval, therefore, especially fasten in the pass with the element fixing apparatus M being arranged at downstream, there is the advantage of the densification of raising and the printing equipment 1 contributing to handling capacity.Below, this point is described.

Usually, also possessing in element fixing apparatus M side for changing the conveyer belt variable-width mechanism of conveyer belt to the interval of CM, changing the interval of conveyer belt to CM according to the size as the substrate W producing object.Therefore, because be the conveyer belt changeable mechanism of element fixing apparatus M side with which side on front side of device or on rear side of device for benchmark is to change the device of conveyer belt to the interval of CM, or the conveyer belt variable-width mechanism of printing equipment 1 side (substrate support pedestal 10A, 10B) with which side in inside device or outside device for benchmark carries out conveyer belt to the device that changes of interval of 12, and likely the handling capacity of printing equipment 1 or apparatus structure to be had an impact.

The basis point situation of each conveyer belt variable-width mechanism of element fixing apparatus M side and printing equipment 1 side (substrate support pedestal 10A, 10B) is represented the required displacement etc. of the first substrate brace table 10A accepted between position and the first launching position by Figure 13 and Figure 14.

Herein, Figure 13 be printing equipment 1 (substrate support pedestal 10A, 10B) conveyer belt variable-width mechanism with inside device for the schematic diagram of (embodiment shown in Fig. 1 ~ Fig. 4) during benchmark, (a) of this Figure 13 represents that the conveyer belt variable-width mechanism of element fixing apparatus M side is with the situation for benchmark on rear side of device, namely, the conveyer belt be positioned on rear side of device is the situation of fixing conveyer belt, and (b) of this Figure 13 represents that the conveyer belt variable-width mechanism of element fixing apparatus M side is with the situation for benchmark on front side of device.And, Figure 14 be printing equipment 1 (substrate support pedestal 10A, 10B) conveyer belt variable-width mechanism with outside device for benchmark time, namely, for first substrate brace table 10A, the conveyer belt be positioned on front side of device is fixing conveyer belt, for second substrate brace table 10B, be positioned at the schematic diagram that the conveyer belt on rear side of device is (structure contrary with the example of the embodiment shown in Fig. 1 ~ Fig. 4) during fixing conveyer belt.And, (a) of this Figure 14 represents that the conveyer belt variable-width mechanism of element fixing apparatus M side is with the situation for benchmark on rear side of device, and (b) of this Figure 14 represents that the conveyer belt variable-width mechanism of element fixing apparatus M side is with the situation for benchmark on front side of device.In addition, in Figure 13 and Figure 14, fixing conveyer belt mark shade is drawn.And, conveyer belt to 12 interval reach minimum time state draw with solid line.

In each example of these Figure 13 and Figure 14, first, in example shown in (a) of Figure 13, regardless of conveyer belt to 12 interval (i.e. the size of substrate W), the launching position of first substrate brace table 10A, that is, the position that can take out of substrate W to element fixing apparatus M is necessarily.Therefore, regardless of the size of substrate W, the displacement D of the first first substrate brace table 10A accepted between position and launching position is always certain.

In example shown in (b) of Figure 13, when conveyer belt to 12 be spaced apart maximum time, the launching position of first substrate brace table 10A is equal to the example of (a) of Figure 13, but along with conveyer belt to 12 interval diminish, the launching position of first substrate brace table 10A becomes and accepts position side close to first.Therefore, the above-mentioned displacement D of first substrate brace table 10A is equal to the example of (a) of Figure 13 when substrate W is full-size, and diminishes and diminish along with the size of substrate W.

In example shown in (a) of Figure 14, when conveyer belt to 12 be spaced apart maximum time, the launching position of first substrate brace table 10A is equal to the situation of the example of (a), (b) of Figure 13, but along with the size of substrate W diminishes, the launching position of first substrate brace table 10A becomes and accepts position away from first.Therefore, the above-mentioned displacement D of first substrate brace table 10A is equal to the example of (a), (b) of Figure 13 when substrate W is full-size, and diminishes and become large along with the size of substrate W.

In addition, in the example shown in (a) of Figure 14, as shown in the drawing, when substrate W is minimum dimension, relative to the conveyer belt of element fixing apparatus M to CM, first substrate brace table 10A is significantly biased on rear side of device.Therefore, the size L of the fore-and-aft direction of printing equipment 1 correspondingly must be strengthened than the example of Figure 13.

In example shown in (b) of Figure 14, regardless of conveyer belt to 12 interval, the launching position of first substrate brace table 10A is necessarily.Therefore, regardless of the size of substrate W, the displacement D of the first first substrate brace table 10A accepted between position and launching position is always certain.But in the case of this example, the relation of second substrate brace table 10B and element fixing apparatus M is equal to the first substrate brace table 10A of (a) of Figure 14 and the relation of element fixing apparatus M.That is, when substrate W is minimum dimension, when second substrate brace table 10B is arranged at launching position, relative to the conveyer belt of element fixing apparatus M to CM, second substrate brace table 10B can be significantly biased on front side of device.Therefore, when the example of (b) of this Figure 14, in the same manner as the example of (a) of Figure 14, the size L of the fore-and-aft direction of printing equipment 1 must be strengthened than the example of Figure 13.Further, correspondingly, for first substrate brace table 10A, its launching position becomes and accepts position away from first, result, and the above-mentioned displacement D of first substrate brace table 10A becomes the example be greater than shown in Figure 13.

As mentioned above, according to making the conveyer belt variable-width mechanism of printing equipment 1 (substrate support pedestal 10A, 10B) side with the structure (example of Figure 13) for benchmark inside device, no matter element fixing apparatus M conveyer belt variable-width mechanism with front and back which for benchmark, all can make the displacement D of substrate support pedestal 10A, 10B relatively (compared with the situation for benchmark outside device) reduction, and, printing equipment 1 maximization in the Y-axis direction can also be suppressed.Therefore, according to making the conveyer belt variable-width mechanism of printing equipment 1 (substrate support pedestal 10A, 10B) side with the above-mentioned printing equipment 1 for benchmark inside device, the raising of handling capacity and the densification of printing equipment 1 can be contributed to.

Next, the second embodiment of screen printing apparatus involved in the present invention is described with reference to Figure 15.

(a) of Figure 15 schematically shows the screen printing apparatus 1A (hereinafter referred to as printing equipment 1A) involved by the second embodiment with top view.This printing equipment 1A involved by the second embodiment is different from the structure of the printing equipment 1 of the first embodiment at following point.

In this printing equipment 1A, on base station 2, be provided with for receiving the conveyer belt of substrate W to Cn1 and for receiving the conveyer belt of substrate W to Cn2 from the second loader L2 from the first loader L1, these conveyer belts are equivalent to described substrate loading unit En1, En2 to the position that Cn1, Cn2 are arranged respectively.And be provided with for substrate W being taken out of conveyer belt to element fixing apparatus M1 to Cx, this conveyer belt is equivalent to described substrate loading unit En to the position set by Cx.Therefore, in this printing equipment 1A, the position that substrate loading unit En1, En2 and substrate on base station 2 take out of portion Ex is fixing, arranges loader L1, L2 and element fixing apparatus M and form hookup wire corresponding to these positions.That is, not as the first embodiment, according to the printing performing a programme etc. provided from master computer, corresponding to the position of loader L1, L2 and the position of element fixing apparatus M, the position of setting substrate loading unit En1, En2 and substrate take out of the position of portion Ex respectively.In addition, described conveyer belt in the same manner as 12, according to the size of substrate W, changes the interval of conveyer belt to the conveyer belt of Cn1, Cn2, Cx and substrate support pedestal 10A, 10B respectively by conveyer belt variable-width mechanism.

And, each substrate support pedestal 10A, 10B do not have the space (substrate position of readiness) for making follow-up substrate W standby, from loader L1, L2 through substrate loading unit En1, En2 be received into substrate support pedestal 10A, 10B substrate W by be directly transported to printing enforcement division 20A, 20B lower position (printing executing location), clamped by grip unit 14 in this position.In addition, grip unit 14 can move along X-direction in the same manner as the first embodiment, and its movable range is defined to the scope of the relative position can revising template 21 and substrate W when template is reset.

And, though the diagram of omission, but board recognition camera 16 and board-recognition camera 50 are linked to the travel mechanism using motor etc. as drive source, can the position between template 21 and substrate W (camera site) be interposed between and moving from the scope between the position (retreating position) of keeping out of the way outside between template 21 and substrate W.Namely, in this printing equipment 1A, after clamping substrate W and before refitting template 21, board recognition camera 16 and board-recognition camera 50 are interposed between template 21 and this substrate W and also take mark respectively, thus the relative position of recognition template 21 and substrate W, and obtain the above-mentioned correction value (Δ X, Δ Y, Δ R) when template is reset based on its recognition result.

According to the printing equipment 1F of the 7th such embodiment, utilize the printing process of first substrate brace table 10A (move into substrate, clamping substrate, printing, releasing substrate clamping, take out of substrate), with utilize the printing process of second substrate brace table 10B (move into substrate, clamp substrate, printing, releasing substrate clamping, take out of substrate) to be that the mutual substrate that staggers takes out of period while implement concurrently, therefore efficiency can carry out the printing of substrate W well.

And, for the substrate W sent respectively from each loader L1, L2, efficiency can be carried out implement well to share or the printing of different pattern to possess two printing enforcement division 20A, 20B such simple structures.And, as mentioned above, first substrate brace table 10A can be made to accept position from first and to move to the second launching position, and second substrate brace table 10B can be made to accept position from second and move to the first launching position, therefore, it is possible to the destination that takes out of of the substrate W after printing treatment is switched to element fixing apparatus M2, M1 respectively simply.

In addition, in the printing equipment 1F of the 7th embodiment, in its structure, except implementing to intersect as above transporting operation, that is while substrate W is received into first substrate brace table 10A from the first loader L1, while implement printing treatment to this substrate W and take out of to the second element fixing apparatus M2, on the other hand, while substrate W is received into second substrate brace table 10B from the second loader L2, while implement printing treatment to this substrate W and take out of to the printing action of the second element fixing apparatus M2, order transporting operation can also be implemented, that is while substrate W is received into first substrate brace table 10A from the first loader L1, while implement printing treatment to this substrate W and take out of to the first element fixing apparatus M1, on the other hand, while substrate W is received into second substrate brace table 10B from the second loader L2, while implement printing treatment and the action taken out of to the second element fixing apparatus M2 to this substrate W.Now, in this printing equipment 1F, the conveyer belt variable-width mechanism of each substrate support pedestal 10A, 10B also use with inside device for benchmark to change conveyer belt to 12 the structure at interval, therefore in the same manner as printing equipment 1 grade of the first embodiment, fasten in the pass with element fixing apparatus M1, M2 of being arranged at downstream, there is the advantage of the densification of raising and the printing equipment 1 contributing to handling capacity.Below, this point is described.

In Figure 21 ~ Figure 24, for printing equipment 1F, the basis point situation of each conveyer belt variable-width mechanism of element fixing apparatus M1, M2 side and printing equipment 1 side (substrate support pedestal 10A, 10B) is represented to the required displacement etc. of the first substrate brace table 10A accepted between position and launching position, Figure 21 and Figure 22 is for the situation of order transporting operation, Figure 23 and Figure 24, for the situation of intersection transporting operation, represents the required displacement etc. of first substrate brace table 10A respectively.

Herein, Figure 21 and Figure 23 is printing equipment 1 (substrate support pedestal 10A, conveyer belt variable-width mechanism 10B) with inside device for schematic diagram during benchmark, (a) of this Figure 21 and (a) of Figure 23 represents element fixing apparatus M1, the conveyer belt variable-width mechanism of M2 side take inner side as the situation of benchmark, namely, for the first element fixing apparatus M1, conveyer belt on rear side of device is fixing conveyer belt, on the other hand, for the second element fixing apparatus M2, conveyer belt on front side of device is the situation of fixing conveyer belt, (b) of this Figure 21 and (b) of Figure 23 represents element fixing apparatus M1, the conveyer belt variable-width mechanism of M2 take outside as the situation of benchmark, namely, for the first element fixing apparatus M1, conveyer belt on front side of device is fixing conveyer belt, on the other hand, for the second element fixing apparatus M2, conveyer belt on rear side of device is the situation of fixing conveyer belt.

On the other hand, Figure 22 and Figure 24 is that the conveyer belt variable-width mechanism of printing equipment 1 (substrate support pedestal 10A, 10B) is with the situation for benchmark outside device, namely, for first substrate brace table 10A, the conveyer belt be positioned on front side of device is fixing conveyer belt, for second substrate brace table 10B, the schematic diagram when conveyer belt be positioned on rear side of device is fixing conveyer belt.And, (a) of this Figure 22 and (a) of Figure 24 represents that the conveyer belt variable-width mechanism of element fixing apparatus M1, M2 side take inner side as the situation of benchmark, and (b) of this Figure 22 and (b) of Figure 24 represents that the conveyer belt variable-width mechanism of element fixing apparatus M1, M2 side take outside as the situation of benchmark.

In addition, in Figure 21 ~ Figure 24, fixing conveyer belt mark shade is drawn.And, conveyer belt to 12 interval reach minimum time state draw with solid line.

First, based on Figure 21 and Figure 22, displacement needed for first substrate brace table 10A during order transporting operation is investigated.

In example shown in (a) of Figure 21, regardless of conveyer belt to 12 interval (i.e. the size of substrate W), first launching position of first substrate brace table 10A, that is, the position that can take out of substrate W to element fixing apparatus M is necessarily.Therefore, regardless of the size of substrate W, the displacement D of the first first substrate brace table 10A accepted between position and the first launching position is always certain.

In example shown in (b) of Figure 21, when conveyer belt to 12 be spaced apart maximum time, first launching position of first substrate brace table 10A is equal to the example of (a) of Figure 21, but along with conveyer belt to 12 interval diminish, first launching position of first substrate brace table 10A becomes and accepts position side close to first.Therefore, the above-mentioned displacement D of first substrate brace table 10A is equal to the example of (a) of Figure 21 when substrate W is full-size, and diminishes and diminish along with the size of substrate W.

In example shown in (a) of Figure 22, when conveyer belt to 12 be spaced apart maximum time, first launching position of first substrate brace table 10A is equal to the situation of the example of (a), (b) of Figure 21, but along with conveyer belt to 12 interval diminish, first launching position of first substrate brace table 10A becomes and accepts position away from first.Therefore, the above-mentioned displacement D of first substrate brace table 10A is equal to the example of (a), (b) of Figure 21 when substrate W is full-size, and diminishes and become large along with the size of substrate W.

In example shown in (b) of Figure 22, regardless of conveyer belt to 12 interval, first launching position of first substrate brace table 10A is necessarily, and its position is equal to the situation of the example of (a) of Figure 21.Therefore, regardless of the size of substrate W, the above-mentioned displacement D of first substrate brace table 10A is necessarily, and its displacement D is equal to the example of (a) of Figure 21.

Namely, as the example of such as (a), (b) of Figure 21, make the conveyer belt variable-width mechanism of printing equipment 1F (substrate support pedestal 10A, 10B) with the structure for benchmark inside device, no matter the conveyer belt variable-width mechanism of element fixing apparatus M1, M2 side no matter inside and outside device which side as benchmark, all can make the displacement D of the substrate support pedestal 10A relevant to said sequence transporting operation, 10B relatively (compared with making the conveyer belt variable-width mechanism of printing equipment 1F with the situation for benchmark outside device) reduce.

Next, based on Figure 23 and Figure 24, to intersect transporting operation time first substrate brace table 10A needed for displacement investigate.

In example shown in (a) of Figure 23, when conveyer belt to 12 be spaced apart maximum time, second launching position of first substrate brace table 10A, namely, the position that can take out of substrate W from first substrate brace table 10A to the second element fixing apparatus M2 accepts position away from first the most, and along with conveyer belt to 12 interval diminish, second launching position of first substrate brace table 10A becomes and accepts position side close to first.Therefore, the above-mentioned displacement D of first substrate brace table 10A reaches maximum when substrate W is full-size, and diminishes and diminish along with the size of substrate W.

In (b) of Figure 23 and the example shown in (a) of Figure 24, regardless of conveyer belt to 12 interval, second launching position of first substrate brace table 10A is necessarily, its position be equal in the example of (a) of Figure 23 conveyer belt to 12 be spaced apart maximum time second launching position of first substrate brace table 10A.Therefore, regardless of the size of substrate W, the above-mentioned displacement D of first substrate brace table 10A is necessarily, in the example of (a) of Figure 23, when to be equal to substrate W be full-size.

In example shown in (b) of Figure 24, when conveyer belt to 12 be spaced apart maximum time, second launching position of first substrate brace table 10A is equal to the situation of example of (b) of Figure 23, (a) of 24, but along with conveyer belt to 12 interval diminish, second launching position of first substrate brace table 10A becomes and accepts position away from first.Therefore, the above-mentioned displacement D of first substrate brace table 10A is equal to the example of (b) of Figure 23, (a) of Figure 24 when substrate W is full-size, and diminishes and become large along with the size of substrate W.And in the example shown in (b) of this Figure 24, as shown in the drawing, when substrate W is minimum dimension, relative to the conveyer belt of the second element fixing apparatus M2 to CM2, first substrate brace table 10A is significantly biased on rear side of device.Therefore, the size L of the fore-and-aft direction of printing equipment 1F correspondingly must be strengthened than the example of (a), (b) of Figure 23 and (a) of Figure 24.

Namely, according to (a) of such as Figure 23, printing equipment 1F (substrate support pedestal 10A is made as the example of (b), conveyer belt variable-width mechanism 10B) is with the structure for benchmark inside device, no matter element fixing apparatus M1, the conveyer belt variable-width mechanism of M2 side with which side inside and outside device for benchmark, all can make and the above-mentioned relevant substrate support pedestal 10A of transporting operation that intersects, the displacement D of 10B relatively (compared with the conveyer belt variable-width mechanism of printing equipment 1F with the situation for benchmark outside device) reduces, and, also printing equipment 1F maximization in the Y-axis direction can be suppressed.

Therefore, according to making the conveyer belt variable-width mechanism of substrate support pedestal 10A, 10B with the structure for benchmark inside device, order transporting operation and intersect transporting operation arbitrary situation under, all can the displacement D of substrate support pedestal 10A, 10B be suppressed relatively little, and, printing equipment 1 maximization in the Y-axis direction can be suppressed.Therefore, according to making the conveyer belt variable-width mechanism of printing equipment 1F (substrate support pedestal 10A, 10B) with the above-mentioned printing equipment 1 for benchmark inside device, the raising of handling capacity and the densification of printing equipment 1 can be contributed to.

This printing enforcement division 20 is supported by the device frame outside the figure be arranged on base station 2, as main inscape, comprise template fixed part 22, two squeegee unit 40A, 40B (being called the first squeegee unit 40A, the second squeegee unit 40B) and shooting unit 60 etc.

Template 21 keeps with the state being flatly located at specified altitude assignment position by the template fixed part 22 of this printing equipment 1G regularly.In addition, template 21 used in this printing equipment 1G is formed with mutually different two kinds of printed patterns 211,212 (being called the first pattern 211, second pattern 212) in a slice template, and the mode that template 21 arranges along Y direction with these printed patterns 211,212 is held in described template fixed part 22.Specifically, template 21 is kept to form the following mode arranged, that is, two printed patterns 211,212 take out of portion Ex relative to substrate and equally distribute along Y direction.Further, with first substrate loading unit En1 relative to the first pattern 211 along the arrangement of roughly X-direction, and second substrate loading unit En2 relative to the second pattern 212 along the mode of roughly X-direction arrangement, be provided with this substrate loading unit En1, En2.

The first squeegee unit 40A in squeegee unit 40A, 40B is arranged at the top of the first printed patterns 211 in the described template 21 kept by template fixed part 22, and the second squeegee unit 40B is arranged at the top of the second printed patterns 211 kept by template fixed part 22.That is, when utilizing the first printed patterns 211 in template 21 to print, utilizing the first squeegee unit 40A, when utilizing the second pattern 212 to print, utilizing the second squeegee unit 40B.

These squeegee unit 40A, 40B, respectively as shown in the solid line of Figure 27 and dotted line, can be supported on the device frame outside above-mentioned figure along the mode of X-direction movement, and are individually driven by driving mechanisms such as the screw feed mechanisms that take motor as drive source.

And each squeegee unit 40A, 40B comprise respectively along the elongated single scraper plate 42 of Y direction, for changing scraper plate 42 relative to the blade angle changeable mechanism outside the incline direction of template 21 and the figure at angle of inclination (with reference to Figure 27) and make scraper plate 42 be slidably connected to the scraping plate elevating mechanism etc. outside the figure that is elevated between the retreating position above the presswork height and position of template 21 and this position at it.

Namely, when utilizing the first printed patterns 211 in described template 21 to print, the scraper plate 42 of the first squeegee unit 40A is arranged at presswork position with being set as specified angle relative to the surface (horizontal plane) of substrate W, in this case, the first squeegee unit 40A is driven along X-direction.On the other hand, when utilizing the second printed patterns 212 in described template 21 to print, the scraper plate 42 of the second squeegee unit 40B relative to the surface set of substrate W be specified angle be arranged at presswork position, in this case, the second squeegee unit 40B is driven along X-direction.

Shooting unit 60, for carrying out image recognition to the relative position relation of template 21 and substrate W, possesses and invests the board recognition camera 60a of multiple marks such as the mark of template 21 lower surface or mark from downside shooting and take the board-recognition camera 60b of multiple marks such as the mark of the substrate W supported by baseplate support device 10 or mark from upside.This shooting unit 60 can be arranged in the horizontal direction by the X-Y robot be linked to outside figure two-dimensional movement, based on the control of aftermentioned control device to X-Y robot, be situated between the template 21 of (template refitting before) before printing and substrate W to take above-mentioned each mark.

In addition, this printing equipment 1G possesses the control device being equal to described control device 8, by the unified a series of printing treatment action controlled by described baseplate support device 10, squeegee unit 40A, 40B and shooting unit 60 etc. of this control device, that is, the substrate W accepting to move into from substrate loading unit En1, En2, from substrate portion Ex takes out of to the printing of substrate W and substrate W take out of this series of action.

Next, reference Figure 25 and Figure 28 Benq is in the printing action of the printing equipment 1G of the control of this control device.

Figure 25 is shown schematically in the state of the particular point in time of the printing action carried out continuously in printing equipment 1G, specifically, represent utilize the substrate W of the second pattern 212 in two of template 21 printed patterns 211,212 just implemented print after state.

From as shown in Figure 25 state, first, baseplate support device 10 moves towards launching position, and namely conveyer belt takes out of position corresponding to portion Ex to 12 towards with substrate.And, after removing the clamp position of substrate W, conveyer belt by conveyer belt to 12, on base station 2 to and the driving of conveyer belt CM, while send the substrate W after printing from baseplate support device 10, take out of portion Ex from substrate and take out of to element fixing apparatus M ((a) of Figure 28).

When having taken out of of substrate W, in order to accept follow-up substrate W, baseplate support device 10 has moved to first or second and has accepted position, and namely conveyer belt moves to the position corresponding with first substrate loading unit En1 or second substrate loading unit En2 to 12.Thus, the conveyer belt substrate W moved into from first substrate loading unit En1 or second substrate loading unit En2 being received into baseplate support device 10 is on 12.Such as, shown in (b) of Figure 28, the substrate W moved into is received into conveyer belt on 12, and is set to clamp position at assigned address from first substrate loading unit En1.

When the clamping of substrate W completes, substrate W, as shown in (c) of Figure 28, is arranged at the position below the printed patterns that should print in two printed patterns 211,212 of above-mentioned template 21.Substrate W can be arranged at the lower position of arbitrary printed patterns 211,212 of template 21 by the moving of Y direction of baseplate support device 10, in illustrated example, be arranged at the lower position of the first pattern 211.

Further, before printing, shooting unit 60 first proceeds between substrate W and template 21 from the retreating position of specifying (position shown in Figure 27), after each mark of shooting substrate W and template 21, moves to above-mentioned retreating position.Thus, image recognition is carried out to each position of substrate W and template 21, and obtain template 21 based on these recognition results and offset with the position of substrate W, and obtain and offset the axial correction value of corresponding X-axis, Y-axis and R (Δ X, Δ Y, Δ R) to this position.Such identifying processing and the computing of correction value are carried out based on the image taken by each camera 60a, 60b by above-mentioned control device.

When the end of identification of substrate W etc., substrate W is reset in template 21.Now, based on above-mentioned correction value (Δ X, Δ Y, Δ R), along Y direction drived control baseplate support device 10, by conveyer belt to 12 described travel mechanism, along X-axis and this conveyer belt of R direction of principal axis drived control to 12, thus, template 21 is reset rightly relative to substrate W.

Further, when substrate W completes to the refitting of template 21, in two squeegee unit 40A, 40B with the printed patterns 211 that should print, 212 corresponding squeegee unit work, thus printing is implemented to substrate W.When the example of (c) of Figure 28, the scraper plate 42 of the first squeegee unit 40A is from after avoidance height position declines and moves to presswork height and position, squeegee unit 40 entirety comprising scraper plate 42 moves along X-direction, thus implements printing to substrate W.

At the end of printing, conveyer belt is refitted in the original position of specifying to 12.Namely, by conveyer belt to 12 the driving of above-mentioned travel mechanism, conveyer belt moves along all directions of X-axis, Y-axis and R axle 12, thus, the substrate W clamped by grip unit 14 departs from template 21, and the clamping of grip unit 14 is removed, by the decline of supporting mechanism, substrate W is placed in conveyer belt on 12, and, this conveyer belt to 12 at above-mentioned each conveyer belt to being arranged at the position that can join substrate W between CL1, CL2 and CM.

Like this, when being completed for printing of substrate W, baseplate support device 10 moves to launching position, by conveyer belt to the driving of 12, sends the substrate W after printing from baseplate support device 10, takes out of to element fixing apparatus M while take out of portion Ex from substrate.And, then, while the substrate W moved into from first substrate loading unit En1 or second substrate loading unit En2 is received into baseplate support device 10, any one utilizing in two of template 21 printed patterns 211,212 is printed, and takes out of portion Ex from substrate and take out of to element fixing apparatus M.

According to printing equipment 1G described above, a slice template 21 comprising two printed patterns 211,212 can be utilized to implement printing, in addition, printing equipment 1G can individually while receive plate W from loader L1, L2 of dual system, while implement printing, and take out of the element fixing apparatus M to single system.Therefore, even if arrange printing equipment 1G between the upstream side device (loader L1, L2) and the downstream device (element fixing apparatus M) of single system of dual system, the auxiliary device (switching device shifter) in the past as device is not needed yet, thereby, it is possible to form production line compactly.

In addition, in this printing equipment 1A, the template being formed with mutually different two kinds of printed patterns 211,212 to application is illustrated as the example of template 21, but printed patterns 211,212 also can be congener pattern (the 9th ~ the 13 following embodiment is like this too).
