[0033] In a circuit board conveying device, the circuit board conveying device generally conveys the circuit board by a double - layer row of rollers. In the prior art, a supporting device is usually used to support the transmission shaft of the row of rollers. Among them, the supporting device is generally fixed on the circuit board conveying device. When it is necessary to perform maintenance on the lower - layer row of rollers, the supporting device needs to be removed before the lower - layer row of rollers can be replaced, which is cumbersome and laborious.

[0034] To solve the above problems, please refer to Figures 1 to 6 , the present utility model proposes a supporting device 100. The supporting device 100 includes a first support seat 110. At least two first fixing grooves 110a are formed on one side of the first support seat 110. The first fixing grooves 110a are arranged at intervals along the first direction. The first fixing groove 110a has a first opening 110b;

[0035] The second support base 120, at least two second fixing grooves 120a are formed on one side of the second support base 120 close to the first support base 110. The second fixing grooves 120a are arranged at intervals along the first direction. The second fixing groove 120a has a second opening 120b. One end of the first support base 110 away from the first opening 110b is detachably mounted on the second support base 120 and covers each second opening 120b. Both the first fixing groove 110a and the second fixing groove 120a are used for installing the transmission shaft of the circuit board conveying device 200; and

[0036] The cover body 130 is detachably mounted on the first support base 110 and covers each first opening 110b.

[0037] In this embodiment, the entire support device 100 adopts a detachable design, including the first support base 110 and the cover body 130, which makes installation, maintenance, and replacement more convenient and fast. For example, when the transmission shaft of the upper row roller needs to be replaced, the cover body 130 and the first support base 110 can be simply opened without having to disassemble the entire support device 100; when the transmission shaft of the lower row roller needs to be replaced, only the first support base 110 needs to be opened, and the transmission shaft can be disassembled from the second fixing groove 120a, avoiding the problem of having to disassemble the entire support device 100 when maintaining and servicing the transmission shaft of the lower row roller. In one embodiment, the support device 100 is a bushing bar assembly.

[0038] It can be understood that the number of the first fixing grooves 110a and the second fixing grooves 120a on the first support base 110 and the second support base 120 can be any number. For example, in one embodiment, the number of the first fixing grooves 110a is two or three or four, and the number of the second fixing grooves 120a is two or three or four, that is, the number of the first fixing grooves 110a and the second fixing grooves 120a does not need to be correspondingly set. It should be noted that when the number of the first fixing grooves 110a is the same as the number of the second fixing grooves 120a, the center of each first fixing groove 110a and the center of a second fixing groove 120a are located on a straight line along the second direction. The setting of multiple first fixing grooves 110a and second fixing grooves 120a allows multiple pairs of row rollers to be taken and placed together during assembly or disassembly, thereby improving the installation efficiency of the transmission shaft.

[0039] In one embodiment, both ends of the transmission shaft of the row roller are respectively located on the first support base 110 or the second support base 120 at both ends thereof, that is, the first support base 110 or the second support base 120 is relatively arranged on both sides of the circuit board conveying device 200 to fix the transmission shaft.

[0040] In the embodiment of the present utility model, please refer to Figure 5, one end of the first support base 110 away from the first opening 110b extends in the second direction and is provided with an expansion tube 112. One end of the expansion tube 112 away from the first support base 110 is axially provided with elongated and spaced expansion segments. One end of the second support base 120 close to the second opening 120b is provided with a first clamping groove 120c. The first clamping groove 120c is located between the second opening 120b along the first direction. The expansion segments are located in the first clamping groove 120c and are in tight contact with the second support base 120, so that the first support base 110 and the second support base 120 are detachably connected.

[0041] In this embodiment, through the design of the expansion tube 112 and the expansion segments, the first support base 110 and the second support base 120 can maintain the structural stability after installation, and when maintenance or replacement is required, the connection between the first support base 110 and the second support base 120 can be easily disassembled. This greatly simplifies the maintenance process and reduces the downtime and maintenance costs.

[0042] In the embodiment of the present utility model, please refer to Figure 5 , the number of the first fixing grooves 110a is three. The three first fixing grooves 110a are spaced along the first direction. The three first fixing grooves 110a form a first opening 110b at one end of the first support base 110 along the second direction. The cover 130 covers the three first openings 110b; the number of the expansion tubes 112 is two. The two expansion tubes 112 are arranged at intervals along the first direction. Each expansion tube 112 is located between two adjacent first openings 110b along the first direction.

[0043] In the embodiment of the present utility model, the number of the second fixing grooves 120a is three. The three second fixing grooves 120a are spaced along the first direction. The three second fixing grooves 120a form a second opening 120b at one end of the second support base 120 along the second direction. The first support base 110 is away from covering the three second openings 120b; the number of the expansion tubes 112 is two. The two expansion tubes 112 are arranged at intervals along the first direction. Each expansion tube 112 is located between two adjacent second openings 120b along the first direction.

[0044] In this embodiment, the two expansion tubes 112 are arranged at intervals along the first direction. Each expansion tube 112 is located between two adjacent first openings 110b. This layout ensures the uniform distribution of the expansion tubes 112 in the support device 100, thereby enhancing the structural stability and load-bearing capacity of the support device 100. Further, the cover 130 can completely cover the three first openings 110b, ensuring that the internal components of the support device 100 are fully protected after installation. This design helps to prevent dust, moisture or other environmental factors from damaging the support device 100, thereby extending its service life.

[0045] In an embodiment of the present utility model, please refer to Figure 3 , on one side of the cover body 130 close to the first support seat 110, a second clamping groove 130a is provided. At one end of the first support seat 110 close to the first opening 110b, a clamping protrusion 113 extending along the first direction is provided. The clamping protrusion 113 is located between two first openings 110b along the first direction, and the clamping protrusion 113 is clamped in the second clamping groove 130a so that the cover body 130 and the first support seat 110 are detachably connected.

[0046] In this embodiment, at one end of the first support seat 110 close to the first opening 110b, a clamping protrusion 113 extending along the first direction is provided, and on one side of the cover body 130 close to the first support seat 110, a second clamping groove 130a is provided. This design allows for a detachable connection between the cover body 130 and the first support seat 110. The advantage of this connection method is that it is convenient for assembly and maintenance, can be quickly disassembled or installed, and is beneficial for the repair and replacement of parts of the device.

[0047] In an embodiment of the present utility model, please refer to Figure 4 and Figure 5 , the opening depth of one first fixing groove 110a along the second direction is greater than the opening depth of the other first fixing groove 110a along the second direction.

[0048] In this embodiment, the fixing grooves with different depths can help to evenly distribute the load. When the support device 100 bears pressure or weight, the fixing groove with a larger depth can better disperse and transmit the force, thereby reducing the risk of local stress concentration and prolonging the service life of the support device 100.

[0049] In an embodiment of the present utility model, both the first fixing groove 110a and the second fixing groove 120a are arc-shaped grooves, and the centers of one first fixing groove 110a and one second fixing groove 120a are collinear along the second direction.
