Specific embodiments

[0025] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Attached Figures 1-4 is the assembly conveyor line with a positioning function according to the present utility model, including a machine table 1, a double-row belt conveyor 2 arranged on the machine table 1, a blocking limiter 3 arranged in the double-row belt conveyor 2 for blocking the carrier, and a positioning mechanism 4 arranged in the double-row belt conveyor 2 and cooperating with the blocking limiter 3 to fix the carrier;

[0027] The positioning mechanism 4 includes a linear module 41 placed along the conveying direction of the double-row belt conveyor 2, a lifting cylinder 42 vertically arranged at the driving end of the linear module 41, a clamping head 43 arranged at the driving end of the lifting cylinder 42, and a pressure sensor arranged on the clamping head 43;

[0028] After the vehicle enters the double-row belt conveyor line 2, the double-row belt conveyor line 2 will send the vehicle to the installation station; when the vehicle arrives at the installation station, the blocking limiter 3 will first block and limit the vehicle, and then the lifting cylinder 42 will drive the clamping head 43 to rise. Then, the linear module 41 will drive the lifting cylinder 42 to drive the clamping head 43 to move towards the blocking limiter 3, and cooperate with the blocking limiter 3 to clamp the vehicle to achieve vehicle positioning; a pressure sensor is provided on the clamping head 43, and when the clamping force reaches the set value, the linear module 41 will stop driving and self-lock.

[0029] Further, as Figure 4 shown, a pressure wheel assembly 5 for making the vehicle fully contact with the double-row belt is further provided at the feeding end of the double-row belt conveyor line 2; the pressure wheel assembly 5 includes a support 51, a connecting rod 52 rotatably arranged on the support 51, a pressure wheel 53 arranged at one end of the connecting rod 52 and located above the belt, and a spring 54 arranged at the other end of the connecting rod 52 to make the pressure wheel 53 approach the belt.

[0030] When the vehicle enters the double-row belt conveyor line 2, the vehicle will flow between the pressure wheel 53 and the belt, which can not only play a guiding role to prevent the vehicle from tilting, but also, under the action of the spring 54, the pressure wheel 53 can make the vehicle fully contact with the belt, increasing the friction force and facilitating the conveyance of the vehicle.

[0031] Further, as Figure 4 shown, the width direction position of the support 51 on the double-row belt conveyor line 2 is adjustable, which can not only reduce the machining accuracy of the support 51, but also facilitate installation and debugging.

[0032] Further, as Figure 4 shown, the pressure wheel assembly 5 further includes a bracket 55 and a downward pressure cylinder 56 vertically arranged on the bracket 55 and located above the spring 54 for driving the connecting rod 52 to make the pressure wheel 53 away from the belt.

[0033] When performing maintenance on the assembly conveyor line, such as replacing the belt, the downward pressure cylinder 56 can be used to drive the connecting rod 52 to make the pressure wheel 53 tilt upward, thus moving away from the belt.

[0034] Further, as Figure 4 shown, the height of the downward pressure cylinder 56 on the bracket 55 is adjustable, which can not only reduce the machining accuracy of the bracket 55, but also facilitate installation and debugging.

[0035] Further, as Figure 2 shown, induction components 6 are provided at both the feeding end and the discharging end of the double-row belt conveyor line 2 to facilitate knowing the entry and exit situation of the vehicle.

[0036] Further, as Figure 2As shown, the induction component 6 can be adjusted in the front and rear positions at the feeding end and the discharging end of the double-column belt conveyor line 2, which is convenient for installation and debugging.

[0037] Furthermore, as Figure 2 shown, the blocking and limiting device 3 includes a vertically placed blocking cylinder 31, a blocking head 32 arranged on the driving end of the blocking cylinder 31, and a sensor arranged on the blocking head 32;

[0038] After the double-column belt conveyor line 2 knows that a carrier enters through the induction component 6 at the feeding end, it will drive the blocking head 32 to rise through the blocking cylinder 31 to block and limit the articles conveyed by the conveyor line; when the sensor on the blocking head 32 senses an article, it indicates that the material has reached the working position, which is convenient for the positioning mechanism 4 to subsequently clamp and position the carrier.

[0039] Furthermore, the width of the double-column belt conveyor line 2 is adjustable, which can adapt to carriers and PCB boards of different sizes and has strong compatibility.

[0040] Furthermore, as Figures 1-2 shown, the double-column belt conveyor line 2 includes a fixed belt conveyor line 21 fixedly arranged on the machine table 1, a movable belt conveyor line 22 movably arranged on the machine table 1, and a spacing adjustment mechanism 23 for driving the movable belt conveyor line 22 to approach or move away from the fixed belt conveyor line 21; the linear module 41 is arranged on the movable belt conveyor line 22;

[0041] When the double-column belt conveyor line 2 adjusts the spacing according to different sizes of carriers, since the linear module 41 is arranged on the movable belt conveyor line 22, the position of the positioning mechanism 4 can be adjusted synchronously with the movable belt conveyor line 22.

[0042] Furthermore, the spacing adjustment mechanism 23 is a prior art and can be manually adjusted or driven for adjustment.

[0043] Furthermore, as Figure 3 shown, an extension rod 44 pointing to the feeding end of the double-column belt conveyor line 2 is arranged at the driving end of the lifting cylinder 42; a blocking block 45 placed at the same height as the clamping head 43 is arranged on the extension rod 44;

[0044] By arranging the extension rod 44 and the blocking block 45 in the present utility model, after the carrier in the working position is positioned, it can block and limit the carriers that enter later on the double-column belt conveyor line 2, so that the carriers in the working position and the carriers that enter later can maintain a certain spacing.

[0045] The above are only specific application examples of the present utility model, which do not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection rights of the present utility model.
