Description

Technical Field

[0001] The invention relates to a test line, in particular to a semi-automatic test line for a printer. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has an impact action on the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on paper, they are divided into serial printers and line printers. According to the technology used, there are cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

[0003] In order to ensure that the printing equipment can maintain working stability during a long period of operation, the printer must undergo various performance tests before leaving the factory to avoid the situation where the printing equipment cannot be used after being sold to the end customer. The current method for testing printers before leaving the factory is to connect the printer to a corresponding test computer and test the various functions of the printer by operating the computer. The prior art generally assembles one printer and then transports the assembled printer to the test department for independent testing. However, as the speed of modern printer assembly is getting faster and faster, this intermittent operation has been difficult to meet the requirements of modern production. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention proposes a semi-automatic printer test line, which can perform continuous testing operations on multiple assembled printers at the same time, with high testing efficiency.

[0005] To realize the above technical scheme, the present invention provides a semi-automatic printer test line, comprising: a double-speed chain conveyor line arranged in a transverse direction, the double-speed chain conveyor line is designed as an upper and lower layer, an input lifting platform is arranged at the front end of the double-speed chain conveyor line, an output lifting platform is arranged at the rear end of the double-speed chain conveyor line, and a tooling pallet is placed on the double-speed chain conveyor line; a ceiling detection mechanism installed above the middle of the double-speed chain conveyor line, the ceiling detection mechanism includes a ceiling platform, and a plurality of test computer groups are installed in the transverse direction along the upper edge of the ceiling platform, each test computer group includes two test computers symmetrically arranged in the longitudinal direction; a plurality of roller conveyors installed side by side along the movement direction of the double-speed chain conveyor line below the double-speed chain conveyor line, the roller conveyors and the double-speed chain conveyor line are distributed in a "cross" shape in the horizontal direction, a lifting baffle is installed between two adjacent roller conveyors, and a corresponding test computer group is arranged above each roller conveyor.

[0006] In the above technical scheme, during actual testing, the input lifting platform lifts the tooling pallet from the lower layer of the double-speed chain conveyor line from bottom to top, and the assembled printer is transported from the previous process to the tooling pallet lifted by the input lifting platform, and then the upper layer of the double-speed chain conveyor line transports the printer from front to back. When the printer is transported to a vacant test position (test computer vacant position) below the ceiling detection mechanism, the lifting baffle moves upward to stop the printer, and then the roller conveyor moves to transport the printer to the vacant test position. The operator only needs to connect the printer to the test computer above the ceiling detection mechanism to conduct the test. Since multiple test positions are set on this test line, continuous and independent testing operations of multiple printers can be achieved. After the test is completed, the operator pushes the tested printer onto the double-speed chain conveyor line and continues to transport it backwards until it is transported to the output lifting platform. The operator then takes out the printer after the test is completed. The output lifting platform drives the tooling pallet to move to the double-speed chain conveyor line on the lower level, and the double-speed chain conveyor line on the lower level transports it from back to front to the input lifting platform, thus realizing the recycling of the tooling pallet.

[0007] Preferably, an input conveyor belt is provided on one side of the input lifting platform, and the input conveyor belt is used to connect to the previous process. The assembled printer is conveyed to the input lifting platform by the input conveyor belt to realize continuous loading of the printer.

[0008] Preferably, an output conveyor belt is provided at the rear of the output lifting platform. After the test is completed, the qualified printer is taken out from the output lifting platform and placed on the output conveyor belt to be transported backward to the next process.

[0009] Preferably, a maintenance workbench is provided on one side of the tail end of the double-speed chain conveyor line. After the test is completed, the unqualified printer is taken out from the output lifting platform and placed on the maintenance workbench for maintenance.

[0010] Preferably, an operating bench is provided on the ceiling platform on one side of the test computer, a computer mouse is placed on the operating bench, a plurality of power strips are arranged horizontally on the top of the ceiling platform, and a warning light is provided on one side of each test computer to facilitate the power supply and independent operation of the test computer. By setting the warning light, when the test computer is working, the warning light lights up, and when the test computer is vacant, the warning light goes out, indicating that there is a vacant seat.

[0011] Preferably, a feeding table is provided on the left and right sides of the middle of the double-speed chain conveyor line, on which several printers to be tested can be stored. Once a fault occurs at the front end of the double-speed chain conveyor line, material can be fed from here to avoid the situation where there is vacant space at the rear end of the double-speed chain conveyor line but material cannot be fed.

[0012] Preferably, a feed counter is installed at the front end of the double-speed chain conveyor line, located in front of the first roller conveyor, for counting the amount of feed to the printer.

[0013] The beneficial effect of a semi-automatic printer test line provided by the present invention is that the semi-automatic printer test line has a high degree of automation and can realize automatic feeding, conveying, allocating test card positions and discharging of the printer. A plurality of test positions are arranged on the test line, and continuous testing operations can be performed on a plurality of assembled printers at the same time, with high testing efficiency.

[0025] Embodiment: A semi-automatic test line for a printer.

[0026] Reference Figures 1 to 9 As shown, a semi-automatic test line for a printer comprises:

[0027] The double-speed chain conveyor line 2 is arranged in the transverse direction, and the double-speed chain conveyor line 2 is designed as an upper and lower layer. An input lifting platform 9 is provided at the front end of the double-speed chain conveyor line 2, and an output lifting platform 10 is provided at the rear end of the double-speed chain conveyor line 2. A tooling pallet 13 is placed on the double-speed chain conveyor line 2. An input conveyor belt 1 is provided on one side of the input lifting platform 9. The input conveyor belt 1 is used to connect the previous process. The assembled printer 8 is transported to the input lifting platform 9 by the input conveyor belt 1 to realize continuous loading of the printer 8. An output conveyor belt 5 is provided at the tail end of the output lifting platform 10. After the test is completed, the qualified printer 8 is taken out from the output lifting platform 10 and placed on the output conveyor belt 5 to be transported backward to the next process During the actual test, the input lifting platform 9 lifts the tooling pallet 13 from the lower layer of the double-speed chain conveyor line 2 from bottom to top, and the assembled printer 8 is transported from the previous process to the tooling pallet 13 lifted by the input lifting platform 9, and then the upper layer of the double-speed chain conveyor line 2 transports the printer 8 from front to back. After the test is completed, the printer 8 continues to be transported backward through the double-speed chain conveyor line 2 until it is transported to the output lifting platform 10. The operator takes out the printer 8 after the test is completed, and the output lifting platform 10 drives the tooling pallet 13 to move to the lower layer of the double-speed chain conveyor line 2, and the lower layer of the double-speed chain conveyor line 2 is transported from back to front to the input lifting platform 9 again, so as to realize the recycling of the tooling pallet 13;

[0028] A ceiling detection mechanism 7 is installed above the middle of the double-speed chain conveyor line 2, and the ceiling detection mechanism 7 includes a ceiling platform 71. Fifteen test computer groups are installed horizontally on the ceiling platform 71, and each test computer group includes two test computers 72 arranged symmetrically along the longitudinal direction. An operating stand 76 is provided on the ceiling platform 71 on one side of the test computer 72, and a computer mouse 73 is placed on the operating stand 76. A plurality of power plug boards 75 are provided horizontally on the top of the ceiling platform 71, and a warning light 74 is provided on one side of each test computer 72 to facilitate the power supply and independent operation of the test computer 72. By setting the warning light 74, when the test computer 72 is working, the warning light 74 is on, and when the test computer 72 is vacant, the warning light 74 is off, indicating that there is a vacancy here;

[0029] Fifteen roller conveyors 3 are installed side by side along the moving direction of the double-speed chain conveyor line 2 below the double-speed chain conveyor line 2. The roller conveyors 3 and the double-speed chain conveyor line 2 are distributed in a "cross" shape in the horizontal direction. A lifting baffle 11 is installed between two adjacent roller conveyors 3, and a test computer group is correspondingly arranged above each roller conveyor 3. The left and right ends of the roller conveyors 3 located on the double-speed chain conveyor line 2 are both test positions. When the printer 8 is transported to a vacant test position (test computer vacant position) below the ceiling detection mechanism 7, the lifting baffle 11 moves upward to stop the printer 8, and then the roller conveyor 3 is activated to transport the printer 8 to the vacant test position on the left or right side of the double-speed chain conveyor line 2. The operator only needs to connect the printer 8 to the test computer 72 above the ceiling detection mechanism 7 to conduct the test;

[0030] A maintenance workbench 6 is set on one side of the tail end of the double-speed chain conveyor line 2, and a lighting lamp 4 is installed on the top of the maintenance workbench 6. After the test is completed, the unqualified printer 8 is taken out from the output lifting platform 10 and placed on the maintenance workbench 6 for maintenance. A feeding table 14 is set on the left and right sides of the middle of the double-speed chain conveyor line 2. Several printers 8 ready for testing can be stored on the feeding table 14. Once the front end of the double-speed chain conveyor line 2 encounters a fault, material can be fed from here to avoid vacancies at the rear end of the double-speed chain conveyor line 2 but unable to feed and test. A feed counter 12 is installed at the front end of the double-speed chain conveyor line 2 in front of the first roller conveyor 3 for counting the feed quantity of the printer 8.

[0031] In this embodiment, during the actual test, the input lifting platform 9 lifts the tooling pallet 13 from the lower layer of the double-speed chain conveyor line 2 from bottom to top, and the printer 8 assembled in the previous process is transported to the tooling pallet 13 lifted by the input lifting platform 9 through the input conveyor belt 1, and then the upper layer of the double-speed chain conveyor line 2 transports the printer 8 from front to back. When the printer 8 is transported to a vacant test position (vacant position of the test computer 72) below the ceiling detection mechanism 7, the lifting baffle 11 moves upward to stop the printer 8, and then the roller conveyor 3 is activated to transport the printer 8 to the vacant test position. The operator only needs to connect the printer 8 to the test computer 72 above the ceiling detection mechanism 7 to perform the test. Since thirty test positions are set on this test line, continuous and independent testing operations of thirty printers 8 can be achieved. After the test is completed, the operator pushes the tested printer 8 into the double-speed chain conveyor line 2 and continues to convey it backward until it is conveyed to the output lifting platform 10. The operator takes out the tested printer 8 and places it on the output lifting platform 10. The output lifting platform 10 drives the tooling pallet 13 to move to the double-speed chain conveyor line 2 on the lower layer, and the double-speed chain conveyor line 2 on the lower layer transports it from back to front to the input lifting platform 9, thereby realizing the recycling of the tooling pallet 13.

[0032] The semi-automatic test line of this printer has a high degree of automation, and can realize automatic feeding, conveying, allocating test card positions and discharging of the printer. There are multiple test positions on the test line, which can perform continuous testing operations on multiple assembled printers 8 at the same time, with high testing efficiency.
