Specific embodiments

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present utility model.

[0026] As Figures 1 to 5 shown, the present utility model discloses a turret test chamber. Specifically, the turret test chamber includes a test chamber body and a turret, an indexing head mechanism 5 and a profiled steel bracket 10 located inside the test chamber body; feeding small doors 1 and discharging small doors 8 are respectively opened on the side walls of the test chamber body; the indexing head mechanism 5 is connected to the bottom of the turret to drive the turret to rotate; the turret is of an annular structure, and 12 workstations are arranged along the circumferential direction of the turret, and each workstation includes 6 layers of positioning fixtures 6 arranged up and down. The profiled steel bracket 10 is fixed to the inner bottom of the test chamber body and is located inside the turret. The profiled steel bracket 10 is provided with 6 first detection optical fibers 71 at a position facing the feeding small door 1, and the 6 first detection optical fibers 71 are arranged in one-to-one correspondence with the positioning fixtures 6 of the workstation facing the feeding small door 1; the profiled steel bracket 10 is provided with 6 second detection optical fibers 72 at a position corresponding to the discharging small door 8, and the 6 second detection optical fibers 72 are arranged in one-to-one correspondence with the positioning fixtures 6 of the workstation facing the discharging small door 8.

[0027] Specifically, safety light curtains 3 are provided on both the above-mentioned feeding small door 1 and the discharging small door 8. Thus, when the manipulator extends into the feeding small door 1 to place a product on the positioning fixture 6, the feeding small door 1 will not close. When the manipulator extends into the discharging small door 8 to remove the product from the positioning fixture 6, the discharging small door 8 will not close. Air curtains 4 are provided at the tops of the above-mentioned feeding small door 1 and the discharging small door 8, and the air curtain 4 is connected to the safety light curtain 3 of the corresponding small door. Thus, when the opening of the door is sensed through the safety light curtain 3, air is blown to generate a certain air pressure to prevent heat loss caused by the opening of the door. The feeding small door 1 is connected with a first cylinder 21 for controlling the opening and closing of the feeding small door 1, and the first cylinder 21 is respectively connected to the first detection optical fiber 71 and the safety light curtain 3 on the feeding small door 1. Thus, when the first detection optical fiber 71 detects that there is a product on the positioning fixture 6 and the safety light curtain 3 senses that there is no manipulator inside the feeding small door 1, the cylinder 2 is controlled to close the feeding small door 1. The discharging small door 8 is connected with a second cylinder 22 for controlling the opening and closing of the feeding small door 1, and the second cylinder 22 is respectively connected to the second detection optical fiber 72 and the safety light curtain 3 on the discharging small door 8. Thus, when the second detection optical fiber 72 detects that there is a product on the positioning fixture 6 rotated to the discharging small door 8, the second cylinder 22 is controlled to open the feeding small door 1 so that the manipulator can enter the interior of the test chamber to take out the product. And when the second detection optical fiber 72 detects that there is no product on the positioning fixture 6 and the safety light curtain 3 senses that there is no manipulator inside the discharging small door 8, the cylinder 2 is controlled to close the discharging small door 8.

[0028] In a preferred embodiment of the present utility model, the above-mentioned feeding small door 1 and the discharging small door 8 respectively correspond to two adjacent stations of the turret. For example, if the feeding small door 1 corresponds to the eleventh station, then the discharging small door 8 corresponds to the twelfth station, so that the product placed on the positioning fixture 6 can be rotated and heated in the test chamber for a long enough time to meet the production requirements. This design occupies a very small floor area and has high efficiency compared with the traditional assembly line.

[0029] In a preferred embodiment of the present utility model, rollers 9 are provided at the bottom of the above-mentioned test chamber for convenient movement, and a maintenance door is provided on the test chamber for convenient maintenance.

[0030] Specifically, when a product needs to be placed, the first detection optical fiber 71 detects that there is no product on the positioning fixture 6, and then controls the first cylinder 21 to open the feeding small door 1. At this time, a signal is sent to the external manipulator to carry the product into the test chamber through the feeding small door 1. Then, the safety grating 3 senses that the feeding small door 1 is opened and sends a signal to the air curtain 4 at the top of the feeding small door 1. The air curtain 4 blows air with a certain air pressure to prevent heat loss caused by opening the door inside and outside the chamber. Then, the product is placed on the positioning fixture 6 at the station corresponding to the feeding small door 1. At this time, the first detection optical fiber 71 corresponding to the positioning fixture 6 detects that there is a product on the positioning fixture 6, and the safety grating 3 senses that there is no manipulator and transmits a signal to the first cylinder 21 to close the feeding small door 1; the indexing head mechanism 5 is started to rotate. When the station with the product rotates to the position of the discharging small door 8, the second detection optical fiber 72 corresponding to the discharging small door 8 can detect the product, and then transmits a signal to the second cylinder 22 to open the discharging small door 8. After the external manipulator enters the test chamber through the discharging small door 8, the safety grating 3 senses that the discharging small door 8 is opened and sends a signal to the air curtain 4 at the top of the discharging small door 8. The air curtain 4 blows air with a certain air pressure to prevent heat loss caused by opening the door inside and outside the chamber. The manipulator takes out the product on the positioning fixture 6. At this time, the second detection optical fiber 72 detects that there is no product on the positioning fixture 6, and the safety grating 3 senses that there is no manipulator and transmits a signal to the second cylinder 22 to close the discharging small door 8.
