Description

Write control system

Technical Field

The present invention relates to a writing control system for writing a program to a substrate.

Background

Generally, before an automobile ECU (electronic control unit) product is shipped, the hardware itself needs to be detected, so in the production process flow, a program needs to be written into a substrate ROM, and therefore, during the final high-low temperature inspection, the bottom layer software of the substrate ROM can be matched with a low-high temperature inspection machine to confirm whether the hardware itself has a quality problem.

Conventionally, a substrate writing control apparatus including a writing controller for writing a program to a substrate ROM at one station and a motor for controlling the elevation of a writing station table so that the substrate can enter the writing station is used to write the program to the substrate ROM at one station. In order to meet the demand of increasing the number of customers, it is necessary to add writing stations and substrate writing control devices, for example, the number of substrate writing control devices is increased from one to four, and the number of corresponding writing stations is also increased to four.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved by the utility model

In the above-described detection process, when the number of the write control apparatuses is increased from one to four, it is found that the execution rate of the program written on the substrate ROM is low, and the execution rate is reduced from 95% to about 65% in the case of one apparatus, and the apparatus is in a good-time-bad state. If the execution rate is low, the production efficiency and the number of defective products are directly affected, and if the execution rate of writing to the ROM of the substrate is continuously low (for example, three times), the substrate is scrapped.

The reason why the execution rate is low is that, since all the write controllers are powered by the same power supply system, for example, when one write controller writes a program to the ROM on the substrate of the corresponding one of the write stations and the motors of the other write controllers are activated to control the corresponding other write stations, the motors of the other write controllers instantaneously need a large current to activate, and the operating voltage input to the substrate of the corresponding one of the write stations by the one write controller instantaneously falls outside the operating voltage range.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a write control system capable of preventing an operating voltage for operating a substrate, which is output from a write control device that performs writing on the substrate first, from being instantaneously lowered due to activation of a motor of another write control device, thereby preventing a decrease in the execution rate of writing on the substrate.

In order to solve the above-described problem, a write control system according to the present invention for writing a program on a substrate includes a power supply system for supplying power and a transfer path for sequentially transferring the substrate, and includes: at least two writing stations, each of which is connected to the conveying path and is provided with a connecting jig having a plurality of probes, a conveying rail for conveying the substrate to a designated position corresponding to the connecting jig, and a moving jig for moving the substrate up and down to bring the test point of the substrate into contact with or separate from the probes, from top to bottom; and at least two or more writing control devices respectively corresponding to each of the writing stations for writing a program on the substrate positioned at each of the writing stations, each of the writing control devices including: one end of the motor is connected with the moving jig of each corresponding writing station and controls the moving jig to move up and down; a write controller having a power input terminal connected to the power supply system, a control terminal connected to the other end of the motor and controlling the motor to operate, and a plurality of output terminals including a ground terminal and a voltage output terminal, the plurality of output terminals being connected to the plurality of probes of each of the corresponding write stations, the ground terminal being grounded, the voltage output terminal outputting a voltage for operating the substrate; and the voltage stabilizing and filtering module is configured between the voltage output end and the grounding end.

According to the above-described write control system, since the voltage stabilizing filter module is provided between the voltage output terminal for operating the substrate and the ground terminal, it is possible to prevent the operating voltage for operating the substrate, which is output from the write control device that performs writing on the substrate first, from instantaneously decreasing due to the activation of the motor of the other write control device, and to prevent the execution rate of writing on the substrate from decreasing.

In the writing control system, preferably, when the substrate reaches the predetermined position, the writing controller controls the motor to start, and the motor controls the moving jig of the one writing station to ascend to a position where the plurality of probes are brought into contact with the test points of the one substrate and then stop, so that the writing controller starts writing the program on the substrate.

According to the above-described write control system, it is possible to prevent the operating voltage for operating the substrate, which is output from the write control device, from instantaneously decreasing due to the start of the motor, thereby preventing the execution rate of writing on the substrate from decreasing.

In addition, in the write-in control system, preferably, when the write-in controller finishes writing the program on the substrate, the write-in controller controls the motor to start, the motor controls the moving jig to descend to the position where the substrate returns to the designated position and then stops, and the substrate leaves the write-in station through the conveying track.

According to the above-described write control system, it is possible to prevent the operating voltage for operating the substrate, which is output from the write control device that is performing writing on the substrate, from instantaneously decreasing due to the start of the motor.

In the write control system, the voltage stabilizing filter module is preferably formed of a capacitor having a capacitance value of 20 pF.

According to the above writing control system, the execution rate of writing on the substrate can be maintained at 95% or more with a simple configuration.

In the write control system, it is preferable that the voltage stabilizing filter module includes: a first capacitor having one end connected to the voltage output terminal and the other end grounded; an inductor having one end connected to one end of the first capacitor; and a second capacitor having one end connected to the other end of the inductor and the other end grounded.

According to the write control system, the execution rate can be prevented from decreasing with a simple configuration.

In addition, it is preferable that the capacitance values of the first capacitor and the second capacitor are in the range of 10PF to 100PF, and the inductance value of the inductor is in the range of 2.2uH to 10 uH.

According to the above writing control system, the execution rate of writing on the substrate can be maintained at 95% or more.

Preferably, the plurality of output terminals and the plurality of probes are connected by a plurality of intermediate connection harnesses, and the length of the plurality of intermediate connection harnesses is a distance from the write controller to the connection jig.

According to the above-described write control system, the voltage output from the voltage output terminal of the write controller can be made very close to the voltage at the corresponding probe.

Preferably, the voltage regulator circuit is disposed between an intermediate connection harness connected to the voltage output terminal and an intermediate connection harness connected to the ground terminal.

Further, it is preferable that a shield ring is further included, and the shield ring encases the plurality of intermediate connection harnesses.

According to the above write control system, interference from external electromagnetic waves can be suppressed.

Hereinafter, a write control system according to the present invention will be described with reference to the drawings, and the same or corresponding portions will be described with the same reference numerals in the drawings.

The write control system according to the present invention will be described with reference to fig. 1 to 2A and 2B. Fig. 1 is a block diagram showing a configuration of a write control system according to the present invention. Fig. 2A is a plan view showing a structural relationship between the writing station and the transfer flow path in the writing control system according to the present invention. Fig. 2B is a side view showing the structure of a writing station of the writing control system according to the present invention. Note that, for convenience of explanation, the transfer flow path of the write control system is omitted in fig. 1, and is shown in fig. 2A and 2B.

As shown in fig. 1, 2A, and 2B, the write control system 1000 is mainly composed of a power supply system BT, a first system 1000a, a second system 1000B, a transmission path, and a plurality of sensors not shown. The power supply system BT is used to provide the voltage required by the whole write control system, and the power supply input terminals of the first system 1000a and the second system 1000b are respectively connected with the power supply system BT. The transfer path is used for transferring the substrate, and the substrate is sequentially transferred to the writing stations 4a and 4b connected to the transfer path. As shown in fig. 2, the writing stations 4a and 4b are connected to one side of the conveyance path in sequence, but the present invention is not limited thereto, and fig. 2 is merely an example, and may be separated on both sides of the conveyance path.

Next, the configuration of the first system 1000a will be described. The first system 1000a is mainly composed of a write control device 1a and a write station 4a, wherein the write control device 1a mainly includes a write controller 2a, a motor 3a, and a voltage stabilizing filter module 10 a.

One end of the motor 3a is connected to a moving jig 6a described later, and controls the moving jig 6a to move up and down. The other end of the motor 3a is connected to the control terminal CONT of the write controller 2 a.

The write controller 2a has a power supply input terminal BTin connected to the power supply system BT, and the power supply input terminal BTin operates the write controller 2a based on a voltage supplied from the power supply system. The write controller 2a has a control terminal CONT connected to the other end of the motor 3a, and controls the start and stop of the motor. The write controller 2a further includes a plurality of output terminals for writing a program to the board ROM, and the plurality of output terminals include a ground terminal AGND shown in fig. 3 and a voltage output terminal VBATT for operating the board.

The voltage stabilizing filter module 10a is located between the voltage output terminal VBATT of the write controller 2a and the ground terminal AGND, and stabilizes the voltage output from the voltage output terminal VABTT.

Next, the writing station 4a will be explained. As shown in fig. 1, 2A, and 2B, the writing station 4a is located on one side of the conveyance path, and has a pair of support bases 8a connected to one side of the conveyance path, and the pair of support bases 8a are disposed to face each other. The writing station 4a further includes a connecting jig 5a, a moving jig 6a, and a transfer rail 7a from top to bottom. The connection jig 5a is located at the uppermost part of the writing station 4a, and is connected and fixed to the support table 8a by a support rod or the like. A plurality of probes PIN1a-PINna are fixed to the connection jig 5a, and the plurality of probes PIN1a-PINna are passed out of the connection jig 5a through holes or the like, not shown, in the connection jig 5 a. Wherein the number n of the plurality of probes PINna is set to be more than 2.

The transfer rail 7a is a pair of rails disposed inside the pair of support tables so as to face each other, and transfers the substrate transferred from the transfer path to a predetermined position corresponding to the connection jig 5 a. The designated position means that the test points T1a-Tna of the substrate B1 can be in contact with the plurality of probes PIN1a-PINna in a one-to-one correspondence when the substrate B1 is raised after reaching the designated position. The number of the probe points of the substrate is equal to the number of the probes.

The moving jig 6a is normally positioned below the pair of conveying rails 7a and moves up and down by the control of a motor. One or more moving jigs 6a may be provided as long as they can support the substrate to move up and down.

Further, a plurality of output terminals of the write controller 2a and the plurality of probes PIN1a-PINna are connected by a plurality of intermediate connection harnesses. One end of the voltage stabilizing filter module 10a may be connected to an intermediate connection harness connected to a voltage input terminal of the write controller 2a, and the other end may be connected to an intermediate connection harness connected to a ground terminal AGND of the write controller 2 a.

In addition, the above describes the fixed relationship between the connection jig and the supporting platform and the supporting rod, but the connection jig is not limited thereto, and the connection jig can be fixed according to actual requirements as long as the connection jig can be fixed so that the plurality of probes on the connection jig can be in corresponding contact with and conducted with the probe points of the substrate. In addition, although the above description has been made on the case where the transfer rail is located inside the pair of support bases, the transfer rail is not limited to this, and the transfer rail can be flexibly arranged according to the shape of the support bases as long as the substrate transferred from the transfer path can be transferred to the predetermined position corresponding to the connection jig.

In addition, the number of the plurality of probes shown in fig. 1 to 6 is only a schematic representation, and does not represent the number specifically used.

Next, the configuration of the second system 1000b will be described. Like the first system 1000a, the second system 1000b is mainly composed of a write control device 1b and a write station 4b, wherein the write control device 4b mainly includes a write controller 2b, a motor 3b, and a voltage stabilizing filter module 10 b.

One end of the motor 3b is connected to a moving jig 6b described later, and controls the moving jig 6b to move up and down. The other end of the motor 3b is connected to the control terminal CONT of the write controller 2 b.

The write controller 2b has a power supply input terminal BTin connected to the power supply system BT, and the power supply input terminal BTin operates the write controller 2b based on a voltage supplied from the power supply system. The write controller 2b has a control terminal CONT connected to the other end of the motor 3b, and controls the start and stop of the motor. The write controller 2b further includes a plurality of output terminals for writing a program to the board ROM, and the plurality of output terminals include a ground terminal AGND shown in fig. 3 and a voltage output terminal VBATT for operating the board.

The voltage stabilizing filter module 10b is located between the voltage output terminal VBATT of the write controller 2b and the ground terminal AGND, and stabilizes the voltage output from the voltage output terminal VABTT.

Next, the writing station 4b will be explained. As shown in fig. 1 and 2, the writing station 4b is located on one side of the conveyance path, and has a pair of support bases 8b connected to one side of the conveyance path, and the pair of support bases 8b are disposed to face each other. The writing station 4b further includes a connecting jig 5b, a moving jig 6b, and a transfer rail 7b from top to bottom. The connection jig 5b is located at the uppermost part of the writing station 4b, and is connected and fixed to the support table 8b via a support rod or the like. A plurality of probes PIN1b-PINnb are fixed to the connection jig 5b, and the plurality of probes PIN1b-PINnb are passed out of the connection jig 5b through a through hole or the like, not shown, in the connection jig 5 b. Wherein the number n of the plurality of probes PINnb is set to be more than 2. The number of the plurality of probes PINna is equal to that of the plurality of probes PINnb.

The transfer rail 7b is a pair of rails, and is located inside the pair of support bases 8b and arranged to face each other. For transferring the substrate transferred from the transfer path to a designated position corresponding to the connection jig 5 b. The designated position is a position where the test point T1B-Tnb of the substrate B2 can be brought into contact with the plurality of probes PIN1B-PINnb in a one-to-one correspondence when the substrate B2 rises after reaching the designated position.

The moving jig 6b is normally positioned below the pair of conveying rails 7b, and is moved up and down by the control of the motor 3 b. One or more moving jigs 6b may be provided as long as they can support the substrate to move up and down.

Further, a plurality of output terminals of the write controller 2b and the plurality of probes PIN1b-PINnb are connected by a plurality of intermediate connection harnesses. One end of the voltage stabilizing filter module 10b may be connected to an intermediate connection harness connected to a voltage input terminal of the write controller 2a, and the other end may be connected to an intermediate connection harness connected to a ground terminal AGND of the write controller 2 a.

Next, the operation of the first system 1000a and the second system 1000b will be described. First, the first system 1000a will be described as an example.

In the first system 1000a, when the power input terminal BTin of the write controller 2a receives a voltage from the power system BT and starts up, and the substrate B1 enters the write station 4a from the transfer path and is transferred to a predetermined position by the transfer rail 7a, information reaching the predetermined position is notified to the write controller 2a by a position sensor or the like not shown, and the write controller 2a controls the motor 3a to start up, and the motor 3a controls the moving jig 6a of the write station 4a to ascend to a position where the plurality of probes PIN1a-PINna are brought into contact with and conducted to the test point T1a-Tna of the substrate B1, and then stops, and thereafter, the write controller 4a starts a program writing to the ROM of the substrate B1.

When the writing controller 4a finishes writing the program to the ROM of the substrate B1, the writing controller 4a controls the motor 3a to start, the motor 3a controls the moving jig 6a to descend so that the plurality of probes PIN1a-PINna are separated from the test points T1a-Tna of the substrate B1, the motor 3a controls the moving jig 6a to descend to a position where the substrate B1 returns to a predetermined position and then stops, and thereafter, the substrate B1 moves away from the writing station 4a through the transfer rail 7 a.

The operation of the second system 1000b is basically the same as that of the first system 1000a, and therefore, the description thereof is omitted here.

As described above, the write control system 1000 is described by taking as an example a configuration including the first system 1000a including the write control device 1a and the write station 4a and the second system 1000b including the write control device 1b and the write station 4b, but the present invention is not limited thereto, and may be configured by one power supply system BT and a plurality of systems.

With the write control system 1000 of the present invention, substrates are sequentially advanced into the write station via a transport path, for example, when the substrate B1 enters the writing station 4a, the writing controller 2a controls the motor 3a to start, the writing station 4a is thus initially enabled, and the write controller 2a writes to the substrate B1, which, the next substrate B2 enters the writing station 4B, the writing controller 2B controls the motor 3B to start, the writing station 4B is thus started and the writing controller 2B writes to the substrate B2, so that, due to the time difference with which each substrate enters the writing station, the start-up of each writing station is also time-differentiated, and, in addition, since the motor requires a large current at each start-up, therefore, when the write controller 2B controls the motor 3B to start, the voltage output terminal VBATT of the write controller 2a performing writing instantaneously drops the operating voltage output by the substrate B1.

Therefore, by providing the voltage regulator module between the voltage output terminal VBATT of the write controller 2a and the ground terminal AGND, it is possible to prevent the operating voltage for operating the substrate B1, which is output from the write controller 1a that performs writing on the substrate B1 first, from being instantaneously lowered due to the activation of the motor 3B of the write controller 1B, and to improve the execution rate of the ROM write program on the substrate B1.

Similarly, by providing a voltage regulator circuit module between the voltage output terminal VBATT and the ground terminal AGND of each of the write controllers 2a and 2b in each system, it is possible to prevent an instantaneous drop in the operating voltage for operating the substrate, which is output to another write controller due to the start-up of the motor, and to improve the execution rate of the program to be written to the substrate ROM.

FIG. 3 is a specific circuit diagram of a voltage regulator circuit module according to an embodiment of the present invention. In general, basic conditions for writing a program in the substrate ROM are: for the write controller, there are 30 output terminals in total, and only 17 ports are used, wherein the length of the intermediate connection harness to which the write controller is connected to the plurality of probes is about 1m, and the conditions for the respective output terminals are set as follows: AVCCD: 3.3V, TRES: 5V, ATMS: 5V, ATDO: 5V, ATDI: 5V, JCOMP: 5V, VBATT: 12V-14V, AGND: 0V. In addition, the AVCCD terminal, the TRES terminal, the ATMS terminal, the ATDO terminal, the ATDI terminal, the JCOMP terminal, the VBATT terminal and the AGND terminal are connected with a plurality of probes on the connecting jig through intermediate connecting wiring harnesses, and the other output terminals except the AVCCD terminal, the TRES terminal, the ATMS terminal, the ATDO terminal, the ATDI terminal, the JCOMP terminal, the VBATT terminal and the AGND terminal are grounded. The number of the plurality of probes is determined according to the number of outputs of the write controller actually connected thereto. Since the voltage stabilizing filter module is located between the voltage output terminal VBATT of the write controller and the ground terminal AGND, the voltage output from the voltage output terminal VABTT can be stabilized.

Fig. 4 is a circuit diagram showing an example of a voltage regulator circuit module according to an embodiment of the present invention. As shown in FIG. 4, the voltage regulator circuit module is formed by a capacitor. The explanation is based on actual measurement. When the capacitor C is added between the VBATT terminal of the write controller 2a and the ground terminal AGND to 20pF, it can be measured that when the motor 3b in the second write control system 1000b is started, the voltage output from the VBATT terminal of the write controller 2a performing writing is hardly decreased, that is, only decreased from 13.6V to 13.2V, the duration of the instantaneous voltage drop is about 0.04S, and the execution rate of the program for writing to the substrate ROM is increased from 75% to 98% (that is, the execution rate is 95% or more) compared with the case where the voltage output from the VBATT terminal of the write controller 2a is decreased from 13.6V to 10.8V and the duration of the instantaneous voltage drop is about 0.1S when the capacitor C is not added. In addition, in consideration of the operating frequency of the substrate, the capacitance value of the capacitor C is preferably in the range of 10PF to 00 PF.

FIG. 5 is a circuit diagram illustrating another embodiment of a voltage regulator circuit module according to an embodiment of the present invention. The voltage regulation filter block shown in fig. 5 includes capacitors C1, C2, and an inductor L. Capacitor C1 has one end connected to the voltage output terminal of write controllers 1a and 1b, and the other end connected to ground terminal AGND. One end of the inductor L is connected to one end of the capacitor C1, and the other end is connected to one end of the capacitor C2. One end of the capacitor C2 is connected to the other end of the inductor L, and the other end of the capacitor C2 is connected to the ground terminal AGND. Based on the basic conditions for writing to the substrate ROM, when the regulator circuit module shown in fig. 5 is added, the execution rate of writing to the substrate ROM can be 95% or more. In view of the operating frequency of the substrate, C1 ═ C2 is preferable, and in the range of 10PF to 100PF, L is in the range of 2.2uH to 10 uH.

The length of the intermediate connection harness is set to be just the length of connection between the write controllers 2a and 2b and the plurality of probes of the connection jigs 5a and 5b, that is, to be reduced from 1 meter to 0.4 meter, based on R ═ ρ (I/S) where ρ represents the conductor resistivity, I represents the conductor length, and S represents the conductor cross-sectional area, so that the in-line resistance value can be reduced to 60% of the original value. The voltage output by the voltage output of the write controller 2a, 2b can be made very close to the voltage at the corresponding probe.

Further, the voltage regulator circuit module may be disposed between an intermediate connection harness connected to the voltage output terminal VBATT and an intermediate connection harness connected to the ground terminal AGND.

FIG. 6 is a circuit diagram showing another example of a voltage regulator circuit module according to an embodiment of the present invention. As shown in fig. 6, in order to prevent electromagnetic interference between systems, a shield ring may be added to the intermediate connection harness so as to cover the intermediate connection harness. The shield ring may use, for example, a magnetic ring.

Furthermore, while various exemplary embodiments and examples have been described herein, the various features, approaches, and functions described in one or more embodiments are not limited in their application to a particular embodiment, but may be applied to embodiments alone or in various combinations. For example, it is assumed that the present invention includes a case where at least one of the components is modified, added, or omitted, and a case where at least one of the components is extracted and combined with the components of the other embodiments.
