Description

Technical Field

[0001] The utility model relates to the technical field of controllers, in particular to an injection molding machine controller. Background Art

[0002] At present, most controllers used in injection molding machines are general PCB controllers, that is, all wiring terminals are arranged in order of modules and serial numbers, generally divided into strong current area and weak current area. The weak current area can be divided into commonly used functional area and occasionally used analog digital area. The wiring terminals in the functional area can be divided into two types. One type of wiring terminal can be directly connected to the machine, and the other type of wiring terminal needs to be connected to the machine after external components. When using the PCB controller, it is necessary to manually connect the wires one by one according to the circuit diagram. For details, refer to Figure 1 .

[0003] However, this wiring method is generally purely manual operation, and manual wiring has poor consistency and is prone to false connection, wire core breakage, short circuit, etc. In severe cases, there is a risk of misconnection. In addition, in order to achieve a function, all terminal terminals related to the function need to be connected, resulting in numerous and confusing external wiring. In more serious cases, the signal line of a controlled device needs to be connected to different partitions, making the connection more confusing and difficult to troubleshoot when errors occur. Utility Model Content

[0004] The utility model provides an injection molding machine controller in view of the shortcomings of the prior art controller, such as complicated wiring, high labor intensity and low precision.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A controller for an injection molding machine comprises a PCB controller and a plurality of wiring terminals arranged on the PCB controller and electrically connected to the PCB controller. The PCB controller is provided with a wiring regularization area for centrally arranging the wiring terminals of original functional areas to facilitate wiring and simplify external circuits. The wiring regularization area comprises a wiring layer arranged on the PCB controller and a plurality of wiring harness plugs fixedly arranged on the wiring layer and directly connected to the machine. Each wiring harness plug is integrated with a plurality of wiring terminals with the same and / or similar functions. A centralized functional area is provided on the wiring layer, and the centralized functional area is arranged with the remaining wiring terminals in the original functional area that require external components and cannot be integrated in the wiring harness plug.

[0007] With the above scheme, since the connection mode of the high-voltage area is relatively stable, and the analog and digital area is not often used when connected to the machine under normal circumstances, there is no need for frequent wiring; however, since the functional area needs to be adjusted according to the machine model and working conditions, it needs frequent wiring, which will cause the above-mentioned shortcomings caused by manual wiring, so it is necessary to plan the wiring of the functional area to facilitate wiring and simplify external lines. The wiring terminals that can be directly connected to the machine are divided according to the function, and the wiring terminals with the same and / or similar functions are integrated in the same wiring harness plug, that is, there is no need to wire each wiring terminal, only the wiring harness plug and the machine need to be electrically connected. By plugging, the connection steps are simplified, the labor is reduced, and the accuracy of manual wiring is improved, reducing risks; in addition, the external lines are greatly reduced, making the lines simple and clear, which is convenient for subsequent troubleshooting when errors occur. The wiring terminals that need to be connected to external components and then electrically connected to the machine are centrally arranged to form a centralized functional area, which is convenient for the regularization and troubleshooting of the lines.

[0008] Preferably, the centralized functional area includes at least one commonly used function fixed point for centralized arrangement of wiring terminals with commonly used functions and at least one reserved fixed point for centralized arrangement of blank wiring terminals without set functions.

[0009] By adopting the above scheme, the wiring terminals with commonly used functions are arranged together, and the wiring can be selected according to the required function, which is convenient for wiring and troubleshooting; the blank wiring terminals without set functions are arranged together to facilitate the distinction between them and the wiring terminals with functions. At the same time, the wiring is done by reserving points to retain the editability of the PCB controller.

[0010] Preferably, a protection structure for protecting an electrical circuit connected to the wiring terminals in the wiring harness plug and the wiring terminals in the concentrated functional area is provided on the wiring layer.

[0011] By adopting the above solution and setting a protection structure, the safety of the PCB controller when in use is improved.

[0012] Preferably, the protection structure is a fuse integration part arranged on the wiring layer, a plurality of fuses are integrated in the fuse integration part, and each wiring harness plug, common function fixing point and reserved fixing point is electrically connected to at least one fuse.

[0013] By adopting the above scheme, overload, short circuit and other conditions will melt the corresponding fuse, thereby protecting the electrical circuit. In the prior art, the fuse of the electrical circuit is externally connected, which makes the external circuit complicated and difficult to troubleshoot. After the fuse is integrated, the external circuit is further simplified and easy to troubleshoot.

[0014] Preferably, a warning light is provided on one side of each fuse on the wiring layer and is electrically connected to the fuse and lights up when the fuse is blown.

[0015] With the above solution, when the fuse blows, the warning light next to it lights up, making it easy to check for circuit problems.

[0016] Preferably, the PCB controller is provided with a voltage and current signal output terminal, and the voltage and current signal output terminal includes a plurality of voltage signal output terminals and at least one current signal output terminal.

[0017] With the above scheme, there is only a voltage signal output terminal in the prior art, and current output is required under specific working conditions, so an external circuit is required to form a current signal output terminal, which increases the external circuit and operation steps. Therefore, the voltage signal output terminal and the current signal output terminal are directly set on the PCB controller, which can simplify the circuit and operation steps.

[0018] Preferably, any voltage signal output terminal is connected to the amplifier board and the amplifier board is integrated into the PCB controller to form the current signal output terminal.

[0019] By adopting the above scheme, the conversion is performed through an external amplifier board in the prior art, and the external circuits are complicated. After being integrated into the PCB controller, the external circuits are further simplified.

[0020] The utility model has significant technical effects due to the adoption of the above technical solutions: several wiring terminals with the same and / or similar functions are integrated into a wiring harness plug, and it is not necessary to wire each wiring terminal, and it is only necessary to electrically connect the wiring harness plug and the machine, which greatly reduces the external circuits, making the circuits concise and clear, and convenient for subsequent troubleshooting when errors occur; and by plugging in, the connection steps are simplified, the labor is reduced, and the accuracy of manual wiring is improved, reducing risks. In addition, the wiring terminals that need to be electrically connected to the machine after external components are arranged in a centralized functional area, which is convenient for the regularization of the circuits and subsequent troubleshooting when errors occur, simplifying the external circuits to make them concise and clear, while reducing the risks brought by manual wiring.

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Example

[0027] An injection molding machine controller, referring to Figure 2 and Figure 3 , including a PCB controller 1, on which a plurality of wiring terminals 101 are arranged, and the wiring terminals 101 are all electrically connected to the PCB controller 1. Since the connection mode of the high-voltage area itself is relatively stable, and the analog digital area is not often used when connected to the machine under normal circumstances, there is no need for frequent wiring; however, since the functional area needs to be adjusted according to the machine model and working conditions, frequent wiring is required, which will produce many disadvantages caused by manual wiring, so it is necessary to plan the wiring of the functional area. Therefore, a wiring regularization area is provided on the PCB controller 1, and the wiring regularization area centrally arranges the wiring terminals 101 of the original functional area to facilitate wiring and simplify external lines.

[0028] The wiring regularization area includes a wiring layer 2 set on the PCB controller 1, and a plurality of wiring harness plugs 3 are fixedly set on the wiring layer 2. The wiring harness plugs 3 can be directly connected to the machine, and each wiring harness plug 3 integrates a plurality of wiring terminals 101 with the same and / or similar functions. The remaining wiring terminals 101 in the original functional area that require external components and cannot be integrated into the wiring harness plug 3 are concentratedly arranged on the wiring layer 2 to form a centralized functional area. The wiring terminals 101 in the original functional area are divided into wiring terminals 101 that can be directly connected to the machine and wiring terminals 101 that need to be electrically connected to the machine after external components are connected. The wiring terminals 101 that can be directly connected to the machine are further divided according to their functions, and the wiring terminals 101 with the same and / or similar functions are integrated into the same wiring harness plug 3, that is, when in use, it is not necessary to wire each wiring terminal 101, and it is only necessary to electrically connect the wiring harness plug 3 and the machine. By plugging in, the connection steps are simplified, the labor is reduced, and the accuracy of manual wiring is improved, reducing risks; in addition, a large number of external lines are reduced, making the lines simple and clear, which is convenient for subsequent troubleshooting when errors occur. The wiring terminals 101 that need to be electrically connected to the machine after external components are centrally arranged to form a centralized functional area, which is convenient for the regularization and troubleshooting of the lines.

[0029] The centralized function area includes at least one commonly used function fixed point 4 and at least one reserved fixed point 5. The commonly used function points are centrally arranged with wiring terminals 101 with commonly used functions. Wiring can be selected according to the required function, which is convenient for wiring and troubleshooting; the reserved fixed points 5 are centrally arranged with blank wiring terminals 101 without set functions, which are convenient for distinguishing from wiring terminals 101 with functions. At the same time, wiring is done at the reserved points to retain the editability of the PCB controller 1. In this embodiment, three commonly used function fixed points 4 are set, and one reserved fixed point 5 is set.

[0030] A protection structure is provided on the wiring layer 2 for protecting the electric circuit on the wiring layer 2, mainly for protecting the electric circuit connected to the wiring terminal 101 in the wiring harness plug 3 and the wiring terminal 101 in the concentrated functional area. The protection structure is a fuse integration part 6 provided on the wiring layer 2, and a plurality of fuses 601 are integrated in the fuse integration part 6. Each wiring harness plug 3, common function fixed point 4 and reserved fixed point 5 are electrically connected with at least one fuse 601; according to different requirements, each wiring harness plug 3, common function fixed point 4 and reserved fixed point 5 can also be electrically connected with multiple fuses 601. Overload, short circuit and other conditions will melt the corresponding fuse 601, thereby realizing the protection of the electric circuit. In the prior art, the fuse 601 of the electric circuit is externally connected, resulting in complicated external lines and difficulty in troubleshooting. After the fuse 601 is integrated, the external circuit is further simplified and easy to troubleshoot. On one side of each fuse 601 on the wiring layer 2, a warning light 7 is provided which is electrically connected to the fuse 601 and lights up when the fuse 601 blows. When the fuse 601 blows, the warning light 7 next to it lights up, making it easy to check for line problems.

[0031] The PCB controller 1 is provided with a voltage and current signal output terminal 8, which includes several voltage signal output terminals and at least one current signal output terminal. In the prior art, there is only a voltage signal output terminal, and a current signal output needs to be connected under a specific working condition, so an external circuit is required to form the current signal output terminal, which increases the external circuit and operation steps. Therefore, the voltage signal output terminal and the current signal output terminal are directly provided on the PCB controller 1, which can simplify the circuit and operation steps. Connect any voltage signal output terminal on the amplifier board and integrate the amplifier board into the PCB controller 1 to form the current signal output terminal. In the prior art, the conversion is performed through an external amplifier board, and the external circuit is complicated. After being integrated into the PCB controller 1, the external circuit is further simplified. The amplifier board, the connection method between the amplifier board and the voltage signal output terminal, and the technology of integrating the amplifier board into the PCB controller 1 are all prior art, which are not shown in the figure and will not be repeated here.
