Description

Technical Field

[0001] The present invention relates to the technical field of electronic manufacturing, and particularly relates to a carrier speed increasing device for a chain curing furnace. Background Art

[0002] Curing refers to a production process of heating parts, curing resin, and drying in the electronic manufacturing industry to enhance the stress of material bonding. Among them, the container for implementing curing is the curing furnace.

[0003] In production, usually the product carrier is placed on the line body chain, and the line body drives the carrier to pass through the curing furnace to realize this process. However, only the middle section of the line body in most curing furnaces is the working area, and the two ends of the line body are the idle running working sections (as Figure 1 shown). Although it has little impact on production during single-variety and large-batch production, in the multi-variety and variable-batch production mode, for production lines that often change models, the time for products to enter and exit the curing furnace is greatly increased, and then the changeover time of the entire production line is greatly extended, ultimately reducing the production efficiency of the entire production line.

[0004] In addition, due to the requirements of the material properties of some products, the curing process time cannot be shortened, resulting in difficulty in solving the problem by increasing the chain speed. At the same time, although the method of installing differential chains for the curing furnace transformation can also solve the above problems, the cost is large and the required time is long, making it difficult to meet the actual needs.

[0039] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0040] Embodiment:

[0041] As Figures 2 - 3 shown, the embodiments of the present invention provide a carrier speed increasing device for a chain curing furnace, which is integrally and obliquely installed below the front end and / or the rear end of the curing furnace line body through a bracket 11. Since the carrier speed increasing device is installed in the narrow space at the lower part of the idle running section at the front and rear ends of the curing furnace line body, such as a narrow space of 30 mm, it will not interfere with the normal operation of the curing furnace line body. Among them, the carrier speed increasing device located at the front end of the curing furnace line body is used to quickly send the carrier into the baking area; the carrier speed increasing device located at the rear end of the curing furnace line body is used to quickly push the carrier out of the curing furnace line body.

[0042] The vehicle speed increasing device includes a driving component 1, a driven component 2, a chain 3, a chain guide groove 4, a fork 5, a stiffener 6, a first photoelectric sensor 12, a second photoelectric sensor and a PLC.

[0043] The driving component 1 is connected to the driven component 2 through the chain 3, and the chain 3 is arranged in the chain guide groove 4.

[0044] The first photoelectric sensor 12 is installed on one side close to the driving component 1 for monitoring the entry or exit of the vehicle at the front end or the rear end; the second photoelectric sensor is installed on one side close to the driven component 2 for monitoring the entry or exit of the vehicle at the front end or the rear end.

[0045] The fork 5 is installed on the chain 3; as Figure 4 shown, the fork 5 is used to keep the top of it not lower than the vehicle when starting on the raised side following the chain 3; and keep the top of it lower than the vehicle when returning on the lowered side following the chain 3.

[0046] The stiffener 6 is installed on both sides of the chain guide groove 4 for providing additional support for the chain guide groove 4 to avoid the deformation of the guide groove caused by too long speed increasing stroke, and it can be made of aluminum alloy to reduce the weight.

[0047] In an optional embodiment, as Figure 5 shown, the driving component 1 includes a servo motor 7, a speed reducer 8, a driving sprocket 9 and a motor mounting plate 10.

[0048] The output end of the servo motor 7 is connected to the speed reducer 8, the speed reducer 8 is connected to the driving sprocket 9, and the driving sprocket 9 passes through the motor mounting plate 10 and meshes with the chain 3.

[0049] As Figure 6 shown, the driven component 2 includes a driven sprocket 13, a driven wheel seat plate 14, a guide block 15, an adjusting block 16 and a fixing block 17.

[0050] The driven sprocket 13 is installed on the driven wheel seat plate 14 and meshes with the chain 3. There is a transmission path of the chain 3 between the guide block 15 and the driven sprocket 13;

[0051] There is a transmission path of the chain 3 between the guide block 15 and the driven sprocket 13; the adjusting block 16 is used to increase the weight at one end of the driven component 2 to balance both ends of the vehicle speed increasing device; the fixing block 17 is used to install and fix the driven wheel seat plate 14 and the guide block 15 by screws.

[0052] The PLC is used to receive the entry information of the vehicle at the front end or the rear end, and start the servo motor 7 to drive the fork 5 to start; and is used to receive the departure information of the vehicle at the front end or the rear end, and start the servo motor 7 to drive the fork 5 to return.

[0053] In an alternative embodiment, as Figure 7 shown, the fork 5 includes a loop 18 and a mounting hole 19; the loop 18 is used to push the vehicle to slide on the curing furnace line body, and the mounting hole 19 is fixedly connected to the chain 3.

[0054] In an alternative embodiment, as Figure 8 shown, the bracket 11 is connected to the curing furnace line body through screws at the bottom mounting hole 23 and the side mounting hole 20, and is connected to the driving assembly 1 through screws at the front mounting hole 22 and the opening chute 21, where the opening chute 21 is used to adjust the overall inclination angle of the vehicle speed increasing device, so as to prevent the fork from touching the vehicle during the return journey.

[0055] To prevent the vehicle speed increasing device from colliding with the vehicles that have already completed speed increasing when entering the baking area or being pushed out of the curing furnace line body. In an alternative embodiment, in fact, the distance between adjacent vehicles can be set to be greater than the sum of the length of a single vehicle and the diameter of the driving sprocket. Taking the vehicle speed increasing device installed at the front end of the curing furnace line body as an example, the distance is adjusted by separately setting the vehicle conveying interval time for the upstream branch line body of the curing furnace, that is, the length obtained by multiplying the vehicle interval time by the chain speed of the curing furnace line body, which is at least slightly greater than the sum of the vehicle length and the driving sprocket diameter.

[0056] To better help understand the working principle of the vehicle speed increasing device provided by the embodiments of the present invention, the following is introduced in different cases:

[0057] (1) When installed at the front end of the curing furnace line body, when the vehicle enters the curing furnace line body from the upstream branch line body of the curing furnace, the first photoelectric sensor is triggered, and the PLC receives the sensor signal, drives the servo motor to work to rotate the chain, thereby driving the fork from the starting point to contact the end of the vehicle, and pushing the vehicle to slide on the curing furnace line body, finally realizing the vehicle to quickly pass through the empty running section at the entrance of the curing furnace line body; when the vehicle passes through the driven end of the speed increasing device and enters the baking area line body of the curing furnace, the second photoelectric sensor is triggered. At this time, after receiving the signal, the PLC increases the rotation speed of the servo motor to realize the quick return of the fork until the fork reaches the starting point, and stops the motor movement to wait for the next vehicle.

[0058] (2) When installed at the rear end of the curing furnace line body, when the carrier enters the idle running section line body from the baking area of the curing furnace, the first photoelectric sensor is triggered. The PLC receives the sensor signal and drives the servo motor to operate to rotate the chain, thereby driving the fork from the starting point to contact the end of the carrier, and then pushing the carrier to slide on the curing furnace line body, finally realizing the rapid passage of the carrier through the idle running section at the outlet of the curing furnace line body. When the carrier passes through the driving end of the speed increasing device and enters the downstream branch line body of the curing furnace, the second photoelectric sensor is triggered. At this time, after receiving the signal, the PLC increases the rotation speed of the servo motor to realize the rapid return of the fork until the fork reaches the starting point, and stops the motor movement to wait for the next carrier.

[0059] In summary, compared with the prior art, the following beneficial effects are achieved:

[0060] In the embodiment of the present invention, the carrier speed increasing device is integrally and obliquely installed under the front end and / or the rear end of the curing furnace line body through a bracket, and includes a driving component, a driven component, a chain, a chain guide groove, a fork, a first photoelectric sensor and a second photoelectric sensor. After the carrier triggers the first photoelectric sensor, the driving motor drives the fork to start through the chain, and pushes the carrier to slide on the curing furnace line body, so as to quickly pass through the idle running section; after the carrier triggers the second photoelectric sensor, the driving motor drives the fork to return to its original position through the chain, preparing to push the next carrier. Without increasing the chain speed of the curing furnace, the conveying time of the product in the curing furnace is greatly reduced, which is especially suitable for the automated production of multi-variety and variable-batch products, reduces the changeover production time, improves the production efficiency, and has the advantages of simple installation and low cost.
